New Biologic Tulisokibart Beats Placebo in Ulcerative Colitis Trial
In one cohort of 135 patients, the primary endpoint of clinical remission occurred in 26% of those given the novel antibody to tumor necrosis factor–like cytokine 1A (TL1A) vs 1% given placebo (95% CI, 14-37, P < .001). In a smaller cohort of 43 patients genetically pretested for likely response to the new biologic, remission after treatment was only slightly higher at 32% vs 11% (95% CI, 2-38, P = .02).
The incidence of adverse events was similar in both arms, and most events were mild.
The 12-week induction trial, conducted in 14 countries by the ARTEMIS-UC Study Group and led by Bruce E. Sands, MD, MS, AGAF, a professor of medicine at Icahn School of Medicine at Mount Sinai and system chief in the Division of Gastroenterology at Mount Sinai Health System in New York City, was published in The New England Journal of Medicine.
“Our results suggest that important clinical benefit may be achieved through TL1A blockade in patients with UC,” Dr. Sands said in an interview, adding that this is the first rigorous study of a drug class with an entirely new mechanism of action that may be beneficial in other immune-mediated and fibrotic diseases.
“And it is also the first prospective randomized controlled trial in IBD to incorporate a precision-medicine approach using a predictive biomarker for response in a drug development program,” he added.
Dr. Sands stressed the urgent need for new therapies since, despite the approval of multiple new classes of agents, both small molecules and biologics, “there is still a plateau of efficacy in that less than 50% of patients achieve remission at a year.”
He added that UC may progress over time owing to fibrosis of the bowel, a condition not directly or safely addressed by any existing therapies. “Identifying novel targets such as TL1A may allow us to address a different subpopulation of patients who may not respond to the targets addressed by existing therapies,” he said.
In agreement is Jason K. Hou, MD, MS, AGAF, an associate professor of medicine at Baylor College of Medicine and section chief of gastroenterology at Michael E. DeBakey VA Medical Center, both in Houston, Texas. “Although it’s a very exciting time with more options in the last few years for treating UC, even inhibitors with new agents such as JAK inhibitors and interleukin 23 antagonists, many patients have no or only a partial response,” he said in an interview. “Targeting molecules, which has been studied for decades, may offer more than a shot in the dark.”
Why Target TL1A?
Genome-wide studies have shown elevated TL1A, a member of the tumor necrosis factor superfamily, in patients with inflammatory bowel disease (IBD).
“The interaction of TL1A and its ligand, death domain receptor 3, contributes to the immune-mediated inflammation and fibrosis seen in IBD through the downstream production of proinflammatory cytokines by multiple different immune cells, and the elaboration of collagen by fibroblasts,” Dr. Sands explained.
With the intention of targeting TL1A, his group randomly assigned patients with moderate to severe active UC who were glucocorticoid dependent or had not responded to conventional or advanced therapies, with disease extending a minimum of 15 cm from the anal verge. Across arms, the age of the mainly White, non-Hispanic participants ranged from about 37 to about 42, 35%-53% were female, and disease duration was approximately 6-8 years.
The arms received either placebo or intravenous tulisokibart at 1000 mg on day 1 and 500 mg at weeks 2, 6, and 10. Cohort 1 included patients regardless of biomarker status for likelihood of response. Cohort 2 included only patients with a positive test for likelihood of response.
Dr. Hou was surprised that response to tulisokibart vs placebo was not greater in test-identified probable responders. “The biomarker didn’t make a huge difference, just a numerical one,” he said. “It may be that more genes are involved than the test could identify, and response is more complicated. Or perhaps the placebo response was particularly high in this small group. We need a deeper dive into why.”
Earlier Application?
“This was a phase 2 study, so it’s too soon to say if tulisokibart could be used as early therapy or in severe disease,” Sands said. “However, the excellent safety profile and efficacy suggest that these populations should be explored in later studies.
Further work is needed to validate the test to predict higher likelihood of response, he added, and recruiting for a phase 3 study is now underway.
The study was supported by Prometheus Biosciences, a subsidiary of Merck. Dr. Sands disclosed multiple ties to private companies, including research support, consulting, data safety monitoring, travel, a gift, and a stock option. Several coauthors reported, variously, research support from and/or consulting for multiple private companies. Others reported employment, variously, with Prometheus and/or Merck, Spyre Therapeutics, and Mirador Therapeutics, or patent holding for IBD drugs. Dr. Hou had no relevant competing interests to disclose but will participate in the phase 3 trial.

Environmental Pollutants Play a Growing Role in IBD
The culprit environmental substances include heavy and transition metals, air pollutants, pesticides, and industrial contaminants. The latter encompass synthetic chemicals such as perfluoroalkyls and polyfluoroalkyls (PFAs), which are present in many common household products.
In contrast, zinc exposure may have a protective, anti-inflammatory effect, according to a research group led by Maria Manuela Estevinho, MD, of the Department of Gastroenterology of the Unidade Local de Saúde Gaia e Espinho in Vila Nova de Gaia, Portugal.
Published in Gut , the review also found limited data suggesting adverse IBD outcomes such as hospitalizations are more prevalent with increased exposure to air contaminants in particular.
“These data carry relevance toward counseling patients and family members,” coauthor Manasi Agrawal, MD, assistant professor of medicine at the Icahn School of Medicine, Mount Sinai, and a gastroenterologist at Mount Sinai Hospital in New York City, said in an interview. “At the individual level, we can try to decrease our exposure to chemicals; for example, to minimize use of pesticides and products containing in our homes. However, at the broader community level, health policy changes are needed to help with mitigation strategies and curb production.”
The physiological mechanisms by which pollutants raise IBD risk include an exaggerated immune response leading to systemic inflammation, loss of tight junction proteins leading to increased gut permeability, and dysbiosis of the intestinal microbiota.
The review found the following effects for various pollutants:
- Heavy and transition metals such as copper, lead, and cadmium were associated with gut dysbiosis, overgrowth of undesirable species of microorganisms, and loss of tight junction proteins leading to leaky gut. In all studies, individuals with IBD showed higher concentrations of such metals than healthy control individuals. While the specific profile of heavy metals varied across studies, lead, copper, and iron, were linked to IBD risk in more than one study.
- The particulate matter present in air pollution — including agricultural and wood dust as well as volcanic ash and hydrocarbon dioxin — was linked to dysbiosis and tight junction protein loss. Air pollution has also been linked to increased incidence of irritable bowel syndrome.
- Industrial and organic pollutants such as perfluoroalkyl and polyfluoroalkyl compounds, triclocarban, and polychlorinated biphenyls were also associated with gut permeability and/or reduced microbial diversity.
- Pesticides such as PFAs, organochloride and organophosphate compounds, and pyrethroids were associated with loss of tight junction proteins.
- Zinc was linked to an increase in tight junction proteins.
Commenting on the review but not involved in it, Ashwin N. Ananthakrishnan, MBBS, MD, MPH, AGAF, director of the Crohn’s and Colitis Center at Massachusetts General Hospital, and associate professor at Harvard Medical School in Boston, called it a very important study that expands our understanding of the role of environment in IBD.
“While traditionally studies have focused on dietary and other exposures related to personal behavior and lifestyle such as smoking, this expands consideration to exposures at the environmental level, where an individual may have less control,” he said in an interview.
“This shift could be critically important from a policy standpoint as modifying these risk factors may require more societal than individual efforts,” he added. He did offer a caveat, however. “While the review highlights several plausible associations, all of which merit further study, importantly, one should also avoid overinterpreting the results as there are very few high-quality studies that provide robust evidence of an association. So more work is needed.”
Recent research has suggested that environmental exposures affect IBD risk more than genetic predisposition.
As background to this review, the growing industrialization and consumerism of the developing world has seen the global number of IBD cases rise from 3.3 million in 1990 to an estimated 4.9 million in 2019, a jump of 47.5%. In the United States, IBD accounts for more than $25 billion in direct healthcare costs.
In terms of the near future, Dr. Agrawal said, “Next steps would be to measure various chemicals in pre-disease biological samples for objective assessment of the impact of chemicals on IBD risk, and such studies are already underway.”
That would mean using exposure biomarkers with high temporal resolution in preclinical samples, as well as advanced measurement techniques and machine-based composite data analysis to explain the IBD-pollutant relationship. “This approach may also provide insight into the role of different environmental insults in different stages of life and clarify whether the timing of exposure may be more critical than the duration,” the authors wrote.
Dr. Agrawal was supported by the National Institute of Diabetes and Digestive and Kidney Diseases, the International Organization For the Study of Inflammatory Bowel Disease, and the Crohn’s and Colitis Foundation. She reported consulting for Douglas Pharmaceuticals. Other authors reported lecture/consulting fees from multiple pharmaceutical/biomedical companies. Dr. Ananthakrishnan had no relevant conflicts of interest.

Doulas Support Moms-to-Be and Try to Fit Into the Obstetric Care Team
It’s well known that the United States enjoys the dubious distinction of having the worst maternal morbidity and mortality rates among industrialized nations. Maternal mortality in this country increased by 14% from 2018 to 2020, according to the Centers for Disease Control and Prevention’s National Center for Health Statistics.
But a current trend of engaging birth doulas — nonmedical guides offering continuous one-on-one physical and psychological support in the pre-, peri,- and postnatal periods — may be poised to brighten that dismal statistical landscape.
Recent research has shown that mothers matched with a doula are less likely to have a low birth weight baby, less likely to experience a birth complication, and significantly more likely to initiate breastfeeding.
Doula services — even delivered digitally — are seen to lower healthcare costs, reduce cesarean sections, decrease maternal anxiety and depression, and improve communication between healthcare providers and low-income, racially/ethnically diverse pregnant women. Doulas can be especially helpful for mothers dealing with the psychological fallout of miscarriage or stillbirth. They can guide patients in the postpartum period, when problems can arise and when some mothers are lost to medical follow-up, and provide an ongoing source of patient information for the ob.gyn.
“Research has shown that in addition to better outcomes, doula care can shorten labor time and increase patient satisfaction,” said ob.gyn. Layan Alrahmani, MD, in an interview. A maternal-fetal medicine specialist with a focus on high-risk pregnancies among low-income women at Loyola Medicine in Maywood, Illinois, Dr. Alrahmani welcomes doulas to her patients’ antenatal visits.
“Many of my patients who are looking to avoid an epidural will work with a labor doula, in order to stay home as long as possible and to have one-on-one coaching through the pain as things progress,” said Susan Rothenberg, MD, an assistant professor of obstetrics, gynecology, and reproductive science at the Icahn School of Medicine at Mount Sinai and an ob/gyn at Mount Sinai Downtown Union Square in New York City. She added, “When a woman’s partner is squeamish or potentially unavailable, a labor doula can be a great option.”
Another ob.gyn. who enthusiastically embraces doula care is L. Joy Baker, MD, who practices in LaGrange, Georgia, and is affiliated with Wellstar West Georgia Medical Center. “I love it when my patients have a doula. A doula answers a patient’s questions throughout the pregnancy and amplifies the mother’s voice in the medical system and the clinical setting,” Dr. Baker told this news organization.
“They provide important details on patients’ food, housing, and transportation status when the mothers themselves would not bring those up in a short appointment with their doctors,” she said. Dr. Baker called for more recognition of their merit, especially for first-time and high-risk moms.
Efua B. Leke, MD, MPH, an assistant professor at Baylor College of Medicine and chief of obstetrics at Ben Taub Hospital in Houston, Texas, also believes a major benefit of doulas is improved flow of information. “We know that having doulas participate in maternal care can ease communication between pregnant and parturient mothers and their clinical team,” Dr. Leke said. “This is especially important for under-resourced pregnant women for whom morbidity tends to be disparately higher.”
Doulas can also take pressure off embattled ob.gyn. clinical staff. “Our volume of patients is huge, so we have to keep appointments brief,” Dr. Baker said. “The US is currently 8000 ob.gyn.s short, and to make matters worse, we’re seeing more and more obstetrical care deserts.”
Still largely underutilized, doula care is seen by its proponents as important in light of the drastic shortage of ob.gyn.s and the shrinking presence of maternity care in many US counties.
According to a recent March of Dimes report, access to maternity care is waning, with more than 35% of US counties offering no community obstetrical care and 52% providing no maternity care in local hospitals. That translates to long distances and extended travel time for mothers seeking care.
Growth Remains Slow
Although many believe doulas could become part of the solution to the lack of access to maternity care, their acceptance seems to be slow growing. In a 2012 national survey by Declercq and associates, about 6% of mothers used a doula during childbirth, up from 3% in a 2006 national survey. Of those who were familiar with but lacking doula care, just 27% would have chosen to have this service.
“I’d estimate that doulas are still involved in only about 6%-8% of births,” said Shaconna Haley, MA, a certified holistic doula and doula trainer in Atlanta, Georgia.
And are there enough practicing doulas in the United States to put a dent in the current shortfall in pregnancy care? Although no reliable estimate of their numbers exists, a centralized online doula registration service listed 9000 registered practitioners in 2018. Contrast that with the approximately 3.6 million live births in 2023.
Potential for Friction?
Although generally seen as benign and helpful, the presence of a doula can add another layer of people for hard-pressed medical staff to deal with. Can their attendance occasionally lead to an adversarial encounter? Yes, said Dr. Baker, especially in the case of assertive questioning or suggestions directed at medical staff. “There can be some mistrust on the part of clinicians when nonmedical persons start raising concerns and asking questions. Staff can get a little prickly at this.”
In the view of Melissa A. Simon, MD, MPH, a professor of obstetrics and gynecology, preventive medicine, and medical social sciences at Northwestern University Feinberg School of Medicine in Chicago, Illinois, simple, preventable communication breakdown is often the cause of occasional antagonism. “As in all team care approaches, it’s helpful to have upfront conversations with the birthing person, the doula, and any care team members or support people who will be present in the birthing room. These conversations should be about expectations.”
According to Ms. Haley, “As long as the focus stays firmly on the client/patient and not on the other team members, there should be no friction. Medical staff should be aware there will be a doula in attendance and ideally there should be a collaborative team and plan in place before the birth.”
In Dr. Leke’s experience, doulas do not hinder the medical team as long as clinical roles are well clarified and the patient is engaged in her care plan. “Friction can occur when doulas are functioning outside of their scope of practice, such as speaking to the healthcare team on behalf of the mother instead empowering the mother to speak up herself,” she said. “Or, when the healthcare team doesn’t understand the doula’s scope of practice or recognize the doula as a member of the team.”
Added Dr. Rothenberg, “I’ve occasionally run into doulas who imagine I have an ulterior motive when making recommendations to patients when that’s completely untrue. It’s common for women to decide to become doulas because they didn’t feel listened to during their own birthing experience, and for a few of them, it’s hard to not project that onto their clients’ labor situations, creating conflict where it doesn’t need to exist.”
Barriers and Challenges
Unfortunately, the barriers of cost and access remain high for pregnant and birthing mothers from lower socioeconomic echelons who have no or limited insurance. “There also are very few multilingual doulas or doulas from diverse racial-ethnic backgrounds and identities,” Dr. Simon pointed out.
Yet by all indications, Medicaid members who receive doula services experience positive maternal outcomes, even those at higher risk for pregnancy complications.
As for Medicaid coverage of doula services, in a recent Centers for Medicare & Medicaid Services report, just 11 state Medicaid programs were reimbursing doula services, whereas an additional five were in the process of implementing reimbursement.
Doula care is not covered by all private insurance plans either, Dr. Simon said. “Although there are maternity care bundles with payment models that help integrate doula care, and there are ways to use your flexible spending account to cover it.”
Some hospitals may undertake independent initiatives. Dr. Baker’s center is offering antenatal and peripartum doula support for under-resourced mothers thanks to a Health Resources and Services Administration grant.*
But for now, doula services are largely limited to middle- and high-income women able to afford the associated out-of-pocket costs. These mothers are disproportionately White, and the doulas serving them tend to be of the same race and socioeconomic class.
The Future
Dr. Simon foresees an optimal scenario in which a team of doulas works with all birthing persons on a hospital labor floor as well as with a team of clinicians. “It takes a true team approach to ensure an optimal birthing experience and optimal birth outcomes,” she said.
Despite the many challenges ahead, doulas will probably become a permanent fixture in pregnancy, birth, and postpartum care, said Dr. Baker. “Doula care is going to be a game changer, and obstetricians welcome doulas to the obstetrical care team.”
Dr. Alrahmani, Dr. Baker, Ms. Haley, Dr. Leke, Dr. Rothenberg, and Dr. Simon declared no conflicts of interest relevant to their comments.

It’s well known that the United States enjoys the dubious distinction of having the worst maternal morbidity and mortality rates among industrialized nations. Maternal mortality in this country increased by 14% from 2018 to 2020, according to the Centers for Disease Control and Prevention’s National Center for Health Statistics.
But a current trend of engaging birth doulas — nonmedical guides offering continuous one-on-one physical and psychological support in the pre-, peri,- and postnatal periods — may be poised to brighten that dismal statistical landscape.
Recent research has shown that mothers matched with a doula are less likely to have a low birth weight baby, less likely to experience a birth complication, and significantly more likely to initiate breastfeeding.
Doula services — even delivered digitally — are seen to lower healthcare costs, reduce cesarean sections, decrease maternal anxiety and depression, and improve communication between healthcare providers and low-income, racially/ethnically diverse pregnant women. Doulas can be especially helpful for mothers dealing with the psychological fallout of miscarriage or stillbirth. They can guide patients in the postpartum period, when problems can arise and when some mothers are lost to medical follow-up, and provide an ongoing source of patient information for the ob.gyn.
“Research has shown that in addition to better outcomes, doula care can shorten labor time and increase patient satisfaction,” said ob.gyn. Layan Alrahmani, MD, in an interview. A maternal-fetal medicine specialist with a focus on high-risk pregnancies among low-income women at Loyola Medicine in Maywood, Illinois, Dr. Alrahmani welcomes doulas to her patients’ antenatal visits.
“Many of my patients who are looking to avoid an epidural will work with a labor doula, in order to stay home as long as possible and to have one-on-one coaching through the pain as things progress,” said Susan Rothenberg, MD, an assistant professor of obstetrics, gynecology, and reproductive science at the Icahn School of Medicine at Mount Sinai and an ob/gyn at Mount Sinai Downtown Union Square in New York City. She added, “When a woman’s partner is squeamish or potentially unavailable, a labor doula can be a great option.”
Another ob.gyn. who enthusiastically embraces doula care is L. Joy Baker, MD, who practices in LaGrange, Georgia, and is affiliated with Wellstar West Georgia Medical Center. “I love it when my patients have a doula. A doula answers a patient’s questions throughout the pregnancy and amplifies the mother’s voice in the medical system and the clinical setting,” Dr. Baker told this news organization.
“They provide important details on patients’ food, housing, and transportation status when the mothers themselves would not bring those up in a short appointment with their doctors,” she said. Dr. Baker called for more recognition of their merit, especially for first-time and high-risk moms.
Efua B. Leke, MD, MPH, an assistant professor at Baylor College of Medicine and chief of obstetrics at Ben Taub Hospital in Houston, Texas, also believes a major benefit of doulas is improved flow of information. “We know that having doulas participate in maternal care can ease communication between pregnant and parturient mothers and their clinical team,” Dr. Leke said. “This is especially important for under-resourced pregnant women for whom morbidity tends to be disparately higher.”
Doulas can also take pressure off embattled ob.gyn. clinical staff. “Our volume of patients is huge, so we have to keep appointments brief,” Dr. Baker said. “The US is currently 8000 ob.gyn.s short, and to make matters worse, we’re seeing more and more obstetrical care deserts.”
Still largely underutilized, doula care is seen by its proponents as important in light of the drastic shortage of ob.gyn.s and the shrinking presence of maternity care in many US counties.
According to a recent March of Dimes report, access to maternity care is waning, with more than 35% of US counties offering no community obstetrical care and 52% providing no maternity care in local hospitals. That translates to long distances and extended travel time for mothers seeking care.
Growth Remains Slow
Although many believe doulas could become part of the solution to the lack of access to maternity care, their acceptance seems to be slow growing. In a 2012 national survey by Declercq and associates, about 6% of mothers used a doula during childbirth, up from 3% in a 2006 national survey. Of those who were familiar with but lacking doula care, just 27% would have chosen to have this service.
“I’d estimate that doulas are still involved in only about 6%-8% of births,” said Shaconna Haley, MA, a certified holistic doula and doula trainer in Atlanta, Georgia.
And are there enough practicing doulas in the United States to put a dent in the current shortfall in pregnancy care? Although no reliable estimate of their numbers exists, a centralized online doula registration service listed 9000 registered practitioners in 2018. Contrast that with the approximately 3.6 million live births in 2023.
Potential for Friction?
Although generally seen as benign and helpful, the presence of a doula can add another layer of people for hard-pressed medical staff to deal with. Can their attendance occasionally lead to an adversarial encounter? Yes, said Dr. Baker, especially in the case of assertive questioning or suggestions directed at medical staff. “There can be some mistrust on the part of clinicians when nonmedical persons start raising concerns and asking questions. Staff can get a little prickly at this.”
In the view of Melissa A. Simon, MD, MPH, a professor of obstetrics and gynecology, preventive medicine, and medical social sciences at Northwestern University Feinberg School of Medicine in Chicago, Illinois, simple, preventable communication breakdown is often the cause of occasional antagonism. “As in all team care approaches, it’s helpful to have upfront conversations with the birthing person, the doula, and any care team members or support people who will be present in the birthing room.

Genitourinary Symptoms in Men: Canaries in the Coal Mine for Underlying Chronic Disease
At age 57, a senior scientific researcher in Santa Barbara, California, complained of chronic erectile dysfunction (ED) in what had been a sexually active marriage. “I just couldn’t get an erection, let alone sustain one. Apart from that, I maybe felt a bit tired but generally okay,” he said. Though seemingly well otherwise, 18 months later he was dead of a hereditary right-sided colon cancer.
While not all cases of ED are associated with a dire outcome, the genitourinary signals of ED and lower urinary tract symptoms (LUTS), especially nocturia, serve as sentinel indicators of the presence of, or risk factors for, serious chronic conditions. These commonly include cardiovascular disease (CVD), diabetes, and metabolic syndrome and are associated with obesity, depression, and obstructive sleep apnea.
Sometimes these serious conditions may stay under the radar until men seek help for ED or LUTS.
“We know that among men who had a heart attack, 50% had some degree of ED within 3 years of their cardiac event,” Sam Tafari, MBBS, of the Endocrine and Metabolic Unit at Royal Adelaide Hospital in Adelaide, South Australia, said in an interview.
That’s the bad news. The good news is that these two problems may specifically incentivize men to seek timely care for serious conditions they might otherwise not get, according to Dr. Tafari. And primary care doctors are ideally positioned to get men early multifaceted care. He recently coauthored a call to action on this issue in a review appearing in the Journal of Men’s Health.
In Dr. Tafari’s experience, most patients seeking urological care are unaware of the multiple conditions linked to ED and LUTS. “Many consider these to be due to issues like low testosterone, which actually make up a very small proportion of cases of ED,” he said. Aging, obesity, inactivity, smoking, alcohol abuse, and prescription and street drugs can also contribute to the development of ED.
In most affected men, ED is of vascular etiology, with endothelial dysfunction of the inner lining of blood vessels and smooth muscle the common denominator.
This dysfunction causes inadequate blood supply to both the coronary and the penile arteries, so ED and CVD are considered different manifestations of the same systemic disorder. Because the tumescence-controlling cavernosal vessels of the penis are considerably smaller, the same level of arteriopathy causes a more severe reduction in blood in the erectile tissue. As a result, ED often precedes CVD and presents an early opportunity to screen men for CVD.
As to the mechanisms behind LUTS, Peter N. Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
Ask Early, Ask Often
Jeffrey P. Weiss, MD, PhD, chair of the Department of Urology at SUNY Downstate Health Sciences University in Brooklyn, New York, has done research that uncovered a relationship between structural cardiac disease and nocturia. “So if you had to ask a patient a single question that would point to a global health issue, it would be ‘Do you have frequent nighttime urination,’ ” he said.
It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.
Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:
- Are you having trouble with erections or having sex?
- Are you getting up at night to pass urine more than once?
“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”
Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”
Addressing the Issue
Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.
Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”
“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.
Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.
Dr. Tafari received funding from the Hospital Research Foundation and Freemasons Centre for Male Health and Wellbeing in Adelaide, South Australia. Dr. Tafari, Dr. Tsambarlis, Dr. Weiss, and Dr. Richards had no relevant conflicts of interest to declare.

“We know that among men who had a heart attack, 50% had some degree of ED within 3 years of their cardiac event,” Sam Tafari, MBBS, of the Endocrine and Metabolic Unit at Royal Adelaide Hospital in Adelaide, South Australia, said in an interview.
That’s the bad news. The good news is that these two problems may specifically incentivize men to seek timely care for serious conditions they might otherwise not get, according to Dr. Tafari. And primary care doctors are ideally positioned to get men early multifaceted care. He recently coauthored a call to action on this issue in a review appearing in the Journal of Men’s Health.
In Dr. Tafari’s experience, most patients seeking urological care are unaware of the multiple conditions linked to ED and LUTS. “Many consider these to be due to issues like low testosterone, which actually make up a very small proportion of cases of ED,” he said. Aging, obesity, inactivity, smoking, alcohol abuse, and prescription and street drugs can also contribute to the development of ED.
In most affected men, ED is of vascular etiology, with endothelial dysfunction of the inner lining of blood vessels and smooth muscle the common denominator.
This dysfunction causes inadequate blood supply to both the coronary and the penile arteries, so ED and CVD are considered different manifestations of the same systemic disorder. Because the tumescence-controlling cavernosal vessels of the penis are considerably smaller, the same level of arteriopathy causes a more severe reduction in blood in the erectile tissue. As a result, ED often precedes CVD and presents an early opportunity to screen men for CVD.
As to the mechanisms behind LUTS, Peter N. Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
Ask Early, Ask Often
Jeffrey P. Weiss, MD, PhD, chair of the Department of Urology at SUNY Downstate Health Sciences University in Brooklyn, New York, has done research that uncovered a relationship between structural cardiac disease and nocturia. “So if you had to ask a patient a single question that would point to a global health issue, it would be ‘Do you have frequent nighttime urination,’ ” he said.
It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.
Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:
- Are you having trouble with erections or having sex?
- Are you getting up at night to pass urine more than once?
“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”
Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”
Addressing the Issue
Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.
Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”
“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.
Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.
Dr. Tafari received funding from the Hospital Research Foundation and Freemasons Centre for Male Health and Wellbeing in Adelaide, South Australia. Dr. Tafari, Dr. Tsambarlis, Dr. Weiss, and Dr. Richards had no relevant conflicts of interest to declare.

Time-Restricted Eating Fails for Weight Loss and Glucose Homeostasis
, a small randomized controlled trial found.
The results suggested that any effects of TRE on weight observed in prior studies may be due to reductions in caloric intake and not timing, according to Nisa M. Maruthur, MD, MHS, of the Division of General Internal Medicine at the Johns Hopkins School of Medicine in Baltimore, and colleagues.
Published in Annals of Internal Medicine, the 12-week trial randomly assigned 41 adults aged 18-69 years with obesity and prediabetes or diet-controlled diabetes 1:1 as follows: To TRE, involving a 10-hour eating window with 80% of calories consumed before 1 PM, or to UEP, involving a ≤ 16-hour window, with at least 50% of calories consumed after 5 PM. The regimen in each group was based on the OmniHeart unsaturated fat diet and the SPICE study.
“The diet was similar to the DASH [Dietary Approaches to Stop Hypertension] diet for hypertension and maybe a bit higher in unsaturated fat and micronutrients,” said study co-author Scott J. Pilla, MD, MHS, an assistant professor of medicine at the Johns Hopkins Bloomberg School of Public Health, Baltimore, in an interview. For each participant, macro- and micronutrient content remained constant throughout the study period, with total calories individually determined at baseline and ranging from 1600 to 3500 kcal/d. “That differs from some TRE studies in which calories were adjusted according to whether participants lost or gained weight,” he said. “This was a purely mechanistic study to determine the impact of time of eating alone with no change in calories.”
Although the current findings revealed no weight loss advantage, some evidence suggests that limiting the food consumption window to 4-10 hours naturally reduces energy intake by approximately 200-550 calories per day and can result in a loss of 3%-5% of baseline body weight for 2-12 months. In addition, TRE has been shown to improve metabolic risk factors, such as insulin resistance, blood pressure, and triglyceride concentrations — but not in this study.
The Cohort
The mean age was 59 years, 93% of patients were women, and 93% were Black. The mean body mass index was 36, and the mean baseline weight was 96.2 kg — 95.6 kg in the TRE group and 103.7 kg in the UEP group.
At 12 weeks, weight decreased comparably by 2.3 kg (95% CI, 1.0-3.5) in the TRE group and by 2.6 kg (95% CI, 1.5-3.7) in the UEP group. Change in glycemic measures did not differ between the two groups.
Interestingly, self-reporting questionnaires revealed a slight reduction in physical activity in the TRE group, an effect that requires further study. “We don’t know why but anecdotally, some TRE participants said they tended to go to bed earlier,” Dr. Pilla said. Earlier bedtimes may put an end sooner to the daily eating pattern.
Subanalyses of the data are ongoing and will be published later.
“In the context of several clinical trials that suggest a benefit of TRE, our findings suggest that if or when TRE interventions induce weight loss, it is likely in part due to a reduction in energy intake, and therefore, clinicians can counsel patients that TRE may help them lose weight by decreasing their caloric intake,” the authors wrote.
In an accompanying editorial, Krista A. Varady, PhD, and Vanessa M. Oddo, PhD, of the Department of Kinesiology and Nutrition at the University of Illinois–Chicago, said the study results have important clinical implications. “Many patients stop following standard-care diets (such as daily calorie restriction) because they become frustrated with having to monitor food intake vigilantly each day,” they wrote.
Although TRE is no more effective than other diet interventions for weight reduction, it offers a simplified approach to treat obesity by omitting the need for calorie counting. “TRE bypasses this requirement simply by allowing participants to ‘watch the clock’ instead of monitoring calories, while still producing weight loss,” they wrote.
The straightforward nature of this diet makes it well suited for remote delivery, which can reduce the scheduling and financial barriers associated with inpatient visits, they added. “Moreover, TRE does not require the purchase of expensive food products and allows a person to continue consuming familiar foods, making it a high accessible diet for lower-resource populations.”
Gastroenterologists and Obesity
Of late, support has grown for gastroenterologists to become actively involved in obesity treatment — even to “take ownership” of this field.
In a 2023 article in Gut, Michael Camilleri, MD, AGAF, a gastroenterologist at the Mayo Clinic in Rochester, Minnesota, made the case for the natural fit between gastrointestinal (GI) specialists and obesity management. He noted that obesity is a significant risk factor for GI, pancreatic, and liver diseases. It can even affect inflammatory bowel disease.
“Treating obesity starting when patients present in gastroenterology and hepatology clinics has potential to impact serious consequences of obesity such as cardiovascular risks,” he wrote.
Gastroenterologists already treat GI conditions with pharmacologic and surgical interventions that can also be used to treat obesity and improve glycemic control. These include pancreatic lipase inhibitors and incretin, bariatric endoscopy and surgery, and combination therapies targeting metabolic problems.

Cold Snare Resection Safe for Large Nonpedunculated Colorectal Polyps
In findings from Germany’s randomized controlled CHRONICLE trial, published in Gastroenterology , the cold technique almost eliminated major adverse events (AEs) — but at the cost of higher rates of recurrence and residual adenoma at first follow-up.
“The exact definition of the ideal lesions requires further research,” wrote investigators led by Ingo Steinbrück, MD, of the Department of Medicine and Gastroenterology at the Academic Teaching Hospital of the University of Freiburg, Freiburg im Breisgau, Germany. “Further studies have to confirm to what extent polyp size and histology can determine an individualized approach.”
The researchers noted that while hot snare resection is the gold standard for larger nonpedunculated polyps of ≥ 2 cm, previous research has found the cold technique, which resects without cutting and cauterizing current, to be superior for small polyps .
“Our study suggests that sessile serrated lesions larger than 2 cm should be resected with the cold snare. Selected cases of lateral spreading tumors may also be good candidates for cold snare resection when safety concerns are paramount,” Dr. Steinbrück said in an interview. “Cold snare resection is standard of care in our center in these cases, but our data show no superiority over hot snare in terms of resection speed.”
Despite recommendations for its use, the cold snare method appears to be underused in the United States.
The Study
From June 2021 to July 2023, the 19-center intention-to-treat analysis enrolled 363 patients (48.2% women) with a total of 396 polyps and randomly assigned those with polyps of ≥ 20 mm to cold (n = 193) or hot EMR (n = 203). The primary outcome was major AEs such as perforation or post-endoscopic bleeding.
Major AEs occurred in 1.0% of the cold group and in 7.9% of the hot group (P = .001, odds ratio [OR], 0.12; 95% CI, 0.03-0.54).
Rates for perforation and post-endoscopic bleeding were significantly lower in the cold group, with 0 vs 8 (0% vs 3.9%, P = .007) perforations in the two groups, respectively, as well as 1.0% vs 4.4% (P = .040) for postprocedural bleeding.
Somewhat surprisingly, intraprocedural bleeding was also less common in the cold EMR group at 14% vs 23%.
Residual adenoma, however, was found more frequently in the cold group at 23.7% vs 13.8% (OR, 1.94; 95% CI,1.12-3.38; P = .020).
Commenting on the study but not involved in it, Seth Crockett, MD, MPH, AGAF, a professor of medicine in the Division of Gastroenterology and Hepatology at Oregon Health & Science University in Portland, Oregon, called the CHRONICLE findings very important.
“Interestingly, near identical results were found in a recent report from a multicenter US trial presented at DDW earlier this year by Pohl et al., which adds credence to their findings,” he said. “While this study helps move the needle toward using cold EMR for large polyps, it also highlights an Achilles heel of this approach, a higher risk of residual polyps during follow-up.”
In other study findings, postpolypectomy syndrome occurred with similar frequency in both groups (3.1% vs 4.4%, P = .490).
As to the size factor, multivariable analysis revealed that a lesion diameter of at least 4 cm was an independent predictor of major AEs (OR, 3.37), residual adenoma (OR, 2.47), and high-grade dysplasia/cancer for residual adenoma (OR, 2.92).
In the case of suspected sessile serrated lesions, the rate of residual neoplasia was 8.3% (n = 4 of 48; 95% CI, 3.3-19.5) in the cold group and 4.8% (n = 2 of 42; 95% CI, 1.3-15.8) in the hot group (P = .681).
As for laterally spreading tumors (LSTs), Dr. Steinbrück said, “The higher recurrence rate after cold snare resection of LST nodular mixed types is unacceptable, and therefore, hot snare EMR with margin coagulation should be the treatment of choice.
“For LST granular type homogeneous and LST nongranular type without suspicion of malignancy, cold snare EMR with additional measures such as margin coagulation may be an option in selected cases — for example, when the risk of delayed bleeding is high,” he said.
Implications
This study has several implications, Dr. Crockett said. First, more research and innovation are needed to develop techniques to maximize complete resection during cold EMR and minimize residual polyp rates. “Ideally, this would involve other cold techniques so as not to offset the safety benefits of cold EMR,” he noted.
Second, patient selection is important, as cold EMR is likely more suitable for those with serrated lesions and for those in whom follow-up can be assured, he added. “For patients who have the largest polyps, particularly lesions of the laterally spreading tumor, nodular mixed type, and those who do not wish to participate in surveillance, hot EMR may be preferable, at least at this point.”
The authors agreed that new technical development that improves the outcomes and cost-effectiveness of cold snare polypectomy and combines its demonstrated safety with recurrence reduction is necessary, as are studies to identify optimal candidate lesions.
“The next step is to evaluate whether cold snare EMR with additional measures leads to a recurrence rate comparable to hot snare EMR with margin coagulation,” Dr. Steinbrück said. “If this is the case, cold snare resection may be the future treatment of choice for all large nonpedunculated polyps without suspected malignancy in the colorectum.”
This work was supported by the Gastroenterology Foundation, Küsnacht, Switzerland. Dr. Steinbrück reported lecture fees and travel grants from Olympus Medical, a polypectomy device maker, and Falk Pharma. Numerous coauthors disclosed financial relationships with pharmaceutical and medical device companies, including Olympus Medical. Dr. Crockett disclosed no competing interests relevant to his comments.

The researchers noted that while hot snare resection is the gold standard for larger nonpedunculated polyps of ≥ 2 cm, previous research has found the cold technique, which resects without cutting and cauterizing current, to be superior for small polyps .
“Our study suggests that sessile serrated lesions larger than 2 cm should be resected with the cold snare. Selected cases of lateral spreading tumors may also be good candidates for cold snare resection when safety concerns are paramount,” Dr. Steinbrück said in an interview. “Cold snare resection is standard of care in our center in these cases, but our data show no superiority over hot snare in terms of resection speed.”
Despite recommendations for its use, the cold snare method appears to be underused in the United States.
The Study
From June 2021 to July 2023, the 19-center intention-to-treat analysis enrolled 363 patients (48.2% women) with a total of 396 polyps and randomly assigned those with polyps of ≥ 20 mm to cold (n = 193) or hot EMR (n = 203). The primary outcome was major AEs such as perforation or post-endoscopic bleeding.
Major AEs occurred in 1.0% of the cold group and in 7.9% of the hot group (P = .001, odds ratio [OR], 0.12; 95% CI, 0.03-0.54).
Rates for perforation and post-endoscopic bleeding were significantly lower in the cold group, with 0 vs 8 (0% vs 3.9%, P = .007) perforations in the two groups, respectively, as well as 1.0% vs 4.4% (P = .040) for postprocedural bleeding.
Somewhat surprisingly, intraprocedural bleeding was also less common in the cold EMR group at 14% vs 23%.
Residual adenoma, however, was found more frequently in the cold group at 23.7% vs 13.8% (OR, 1.94; 95% CI,1.12-3.38; P = .020).
Commenting on the study but not involved in it, Seth Crockett, MD, MPH, AGAF, a professor of medicine in the Division of Gastroenterology and Hepatology at Oregon Health & Science University in Portland, Oregon, called the CHRONICLE findings very important.
“Interestingly, near identical results were found in a recent report from a multicenter US trial presented at DDW earlier this year by Pohl et al., which adds credence to their findings,” he said. “While this study helps move the needle toward using cold EMR for large polyps, it also highlights an Achilles heel of this approach, a higher risk of residual polyps during follow-up.”
In other study findings, postpolypectomy syndrome occurred with similar frequency in both groups (3.1% vs 4.4%, P = .490).
As to the size factor, multivariable analysis revealed that a lesion diameter of at least 4 cm was an independent predictor of major AEs (OR, 3.37), residual adenoma (OR, 2.47), and high-grade dysplasia/cancer for residual adenoma (OR, 2.92).
In the case of suspected sessile serrated lesions, the rate of residual neoplasia was 8.3% (n = 4 of 48; 95% CI, 3.3-19.5) in the cold group and 4.8% (n = 2 of 42; 95% CI, 1.3-15.8) in the hot group (P = .681).
As for laterally spreading tumors (LSTs), Dr. Steinbrück said, “The higher recurrence rate after cold snare resection of LST nodular mixed types is unacceptable, and therefore, hot snare EMR with margin coagulation should be the treatment of choice.
“For LST granular type homogeneous and LST nongranular type without suspicion of malignancy, cold snare EMR with additional measures such as margin coagulation may be an option in selected cases — for example, when the risk of delayed bleeding is high,” he said.
Implications
This study has several implications, Dr. Crockett said. First, more research and innovation are needed to develop techniques to maximize complete resection during cold EMR and minimize residual polyp rates. “Ideally, this would involve other cold techniques so as not to offset the safety benefits of cold EMR,” he noted.
Second, patient selection is important, as cold EMR is likely more suitable for those with serrated lesions and for those in whom follow-up can be assured, he added. “For patients who have the largest polyps, particularly lesions of the laterally spreading tumor, nodular mixed type, and those who do not wish to participate in surveillance, hot EMR may be preferable, at least at this point.”
The authors agreed that new technical development that improves the outcomes and cost-effectiveness of cold snare polypectomy and combines its demonstrated safety with recurrence reduction is necessary, as are studies to identify optimal candidate lesions.
“The next step is to evaluate whether cold snare EMR with additional measures leads to a recurrence rate comparable to hot snare EMR with margin coagulation,” Dr. Steinbrück said. “If this is the case, cold snare resection may be the future treatment of choice for all large nonpedunculated polyps without suspected malignancy in the colorectum.”

Type 2 Diabetes Fracture Risk Likely Due to Impaired Physical Function
, according to a Swedish prospective observational study in JAMA Network Open.
The study was conducted in more than 3000 Swedish women by Mattias Lorentzon, MD, a professor of geriatric medicine at Gothenburg University, and chief physician at the Osteoporosis Clinic at Sahlgrenska University Hospital in Mölndal, and colleagues.
Older women with T2D had higher BMD, better bone microarchitecture, and a similar bone material strength index (BMSi) but poorer physical performance and higher fracture risk than women without diabetes.
Women with T2D had 9.1% higher body weight, a 9.5% higher body mass index (BMI), and 6.3% higher appendicular lean mass index (lean mass divided by height squared) than controls.
The T2D group also had a lower prevalence of reported osteoporosis medication use vs controls: 3.4% vs 7.5%, respectively.
Prolonged diabetes treatment and insulin use were associated with higher fracture risk and poorer physical performance despite better bone characteristics.
“Our results demonstrate that checking and monitoring physical function is important to identify diabetes patients with a high risk of fractures and suggest that improving physical function may be important to reduce the risk of fractures in these patients,” Dr. Lorentzon told this news organization.
He speculated that the better bone microarchitecture in women with T2D could be due to both higher body weight and adiposity as well as to hormonal differences such as higher estradiol levels.
Study Details
A fractures study was performed in the Gothenburg area from March 2013 to May 2016 with follow-up of incident fracture data completed in March 2023. Data were collected from questionnaires and through examination of anthropometrics, physical function, and bone measurements using dual-energy x-ray absorptiometry and high-resolution peripheral computed tomography. A subsample underwent bone microindentation to assess BMSi.
Among the cohort’s 3008 women, ages 75-80 (mean, 77.8), 294 patients with T2D were compared with 2714 same-age unaffected women.
During a median follow-up of 7.3 years, 1071 incident fractures, 853 major osteoporotic fractures, and 232 hip fractures occurred. In models adjusted for age, BMI, clinical risk factors, and femoral neck BMD, T2D was associated with an increased risk of any fracture: hazard ratio (HR), 1.26; (95% CI, 1.04-1.54), and major osteoporotic fracture (HR, 1.25; 95% CI, 1.00-1.56).
Most fractures were due to falls, with the most common affected sites being the forearm, upper arm, spine, and hip, Dr. Lorentzon said.
Among the findings:
- In bone microarchitecture, women with T2D had higher BMD at all sites: total hip, 4.4% higher; femoral neck, 4.9% higher; and lumbar spine, 5.2% higher.
- At the tibia, the T2D group had 7.4% greater cortical area and 1.3% greater density, as well as 8.7% higher trabecular bone volume fraction.
“Our findings regarding BMD are consistent with previous publications showing higher BMD in individuals with T2D compared with those without diabetes,” Dr. Lorentzon said. A 2012 meta-analysis, for example, showed higher BMD levels in T2D patients. “Some smaller studies, however, have found worse bone microstructure and lower bone material strength in contrast to the results from our study,” Dr. Lorentzon said.
- There was no difference in BMSi, with a mean of 78 in both groups.
- The T2D group had lower performance on all physical function tests: a 9.7% lower grip strength, 9.9% slower gait speed, and 13.9% slower timed up-and-go time than women without diabetes.
“We found all parameters regarding physical function, such as muscle strength, balance, and performance, were much worse in women with diabetes than in those without,” Dr. Lorentzon said. “Dizziness could also be a contributor to the increased risk of falls, but this factor was not investigated in our study.”
Commenting on the study but not involved in it, Anthony J. Pick, MD, an endocrinologist at Northwestern Medicine Lake Forest Hospital in Lake Forest, Illinois, said sarcopenia is a common and often under-recognized problem in older adults and is especially prevalent in T2D, obesity, and heart failure. “I believe that ‘exercise is medicine’ is a key concept for metabolic and osteoporosis patients — and wellness and longevity in general — and I certainly hope studies like this drive awareness of the importance of engaging in strengthening exercises.”
Dr. Pick noted some nuances in this study suggesting there may be some impairments in bone quality beyond the strength and fall risk issue, “so this is likely a complex area.”

More Access to Perinatal Mental Healthcare Needed
Despite federal legislation improving healthcare access, concerted efforts are still needed to increase evidence-based treatment for maternal perinatal mental health issues, a large study of commercially insured mothers suggested. It found that federal legislation had variable and suboptimal effect on mental health services use by delivering mothers.
In the cross-sectional study, published in JAMA Network Open, psychotherapy receipt increased somewhat during 2007-2019 among all mothers and among those diagnosed with perinatal mood and anxiety disorders (PMADs). The timeline encompassed periods before and after passage of the Mental Health Parity and Addiction Equity Act (MHPAEA) of 2008 and the Patient Protection and Affordable Care Act (ACA) of 2010.
The investigators, led by Kara Zivin, PhD, MS, MFA, a professor of psychiatry in the University of Michigan’s School of Public Health at Ann Arbor, found the results varied by policy and between the overall delivering population and the PMAD population. “We did not find a statistically significant immediate change associated with the MHPAEA or ACA in the overall delivering population, except for a steady increase in delivering women who received any psychotherapy after ACA,” Dr. Zivin and colleagues wrote.
The researchers looked at private insurance data for 837,316 deliveries among 716,052 women (64.2% White), ages 15-44 (mean 31.2), to assess changes in psychotherapy visits in the year before and after delivery. They also estimated per-visit out-of-pocket costs for the ACA in 2014 and the MHPAEA in 2010.
In the PMAD population, the MHPAEA was associated with an immediate increase in psychotherapy receipt of 0.72% (95% CI, 0.26%-1.18%; P = .002), followed by a sustained decrease of 0.05% (95% CI, 0.09%-0.02%; P = .001).
In both populations, the ACA was associated with immediate and sustained monthly increases in use of 0.77% (95% CI, 0.26%-1.27%; P = .003) and 0.07% (95% CI, 0.02%-0.12%; P = .005), respectively.
Post MHPAEA, both populations experienced a slight decrease in per-visit monthly out-of-pocket costs, while after the ACA they saw an immediate and steady monthly increase in these.
Although both policies expanded access to any psychotherapy, the greater number of people receiving visits coincided with fewer visits per person, the authors noted. “One hypothesis suggests that the number of available mental health clinicians may not have increased enough to meet the new demand; future research should better characterize this trend,” they wrote.
In addition, a lower standard cost per visit may have dampened the incentive to increase the number of mental health clinicians, they conjectured. These factors could explain why the PMAD group appeared to experience a decrease in the proportion receiving any psychotherapy after the MHPAEA’s implementation.
The findings should be reviewed in the context of the current mental health burden, the authors wrote, in which the shortage of mental health professionals means that less than 30% of mental healthcare needs are being met.
They called for more measures to mitigate the excess burden of PMADs.

Environment More Than Genes Affects Age of IBD Diagnosis
a large study of IBD patients reported.
Published in Clinical Gastroenterology and Hepatology , the study found that environment influences the onset of both ulcerative colitis (UC) and Crohn’s disease (CD), and exposures typical in Western society lower the age of diagnosis. These factors include birth in a developed nation, delivery by C-section, and more bathrooms in the home, according to Oriana M. Damas, MD, MSCTI, an associate professor of clinical medicine at the University of Miami Miller School of Medicine in Florida and colleagues.
Environmental factors explained 21% of the variance in age of CD diagnosis and 39% of the variance in age of UC diagnosis. In models incorporating both genetic and environmental risk scores, the environment was the only significant factor associated with younger age of IBD diagnosis in all groups.
Several epidemiologic studies have examined environmental culprits in IBD, and others have examined genetic risk factors, Dr. Damas said in an interview. “But we had not seen any studies that examined the influence of both [of] these on age of IBD development.” Her group’s working hypothesis that environment would have a greater effect than genetics was borne out.
“Additionally, very few studies have examined the contribution of genetics or environmental factors in Hispanic individuals, and our study examined the contribution of these factors in this understudied population,” she added.
According to Dr. Damas, the findings’ most immediate clinical relevance is for counseling people with a family history of IBD. “I think it’s important for concerned patients to know that IBD is not solely genetic and that several environmental factors can shape disease risk to a greater extent than genetic predisposition,” she said
Westernization is increasingly considered a contributor to the global increase in IBD, which has been diagnosed in an estimated 2.39 million Americans . In genetically predisposed individuals, environmental culprits in developed countries are thought to negatively shape the intestinal microbiome’s composition into a less tolerant and more proinflammatory state, the authors noted.
According to the “hygiene hypothesis,” the oversanitization of life in the developed world is partly to blame. “A cleaner environment at home, part of the hygiene hypothesis, has been postulated as a theory to help explain the rise of autoimmune diseases in the 21st century and may play an important part in explaining our study findings,” the authors wrote.
Population-based studies have also pointed to antibiotics, nonsteroidal anti-inflammatory drugs, smoking, cesarean delivery, lack of breastfeeding, and nonexposure to farm animals as other risk factors for IBD.
Study Details
To compare the effect of environmental vs genetic risk factors, the questionnaire-based study surveyed 2952 IBD patients from a tertiary care referral center — 58.9% with CD, 45.83% of Hispanic background, and 53.18% of non-Hispanic White (NHW) ethnicity. There were too few available Black and Asian patients to be included in the cohort. Data were collected from 2017 to 2022.
The mean age of patients was 39.71 years, and 34.14% were defined as born outside of the US mainland. Foreign-born patients were further characterized as from developed nations vs developing nations; 81.3% in this subgroup came from the latter. A detailed questionnaire probed 13 potential environmental factors from type of birth to domestic living conditions, medications, and smoking across several different age groups. Blood was drawn to genotype participants and to create a genetic risk score.
Early plastic water bottle use — which has been linked to inflammatory microplastics in the intestines — and residing in homes with more than one bathroom (and presumably less exposure to infections) were also associated with younger age at diagnosis. Susceptibility to environmental exposures was similar in Hispanic and NHW patients.
“It was interesting to find an association between reported plastic water bottle use and younger age of IBD diagnosis,” said Dr. Damas. “Because this is a self-reported intake, we need more studies to confirm this. However, this finding falls in line with other recent studies showing a potential association between microplastics and disease states, including IBD. The next step is to measure for traces of environmental contaminants in human samples of patients with IBD.”
Unlike previous studies, this analysis did not find parasitic infections, pets, and antibiotics to be associated with age of IBD diagnosis. 
“This is an interesting and important study,” commented Ashwin Ananthakrishnan, MBBS, MPH, AGAF, director of the Crohn’s and Colitis Center at Massachusetts General Hospital in Boston, who was not involved in the study. “There are few environmental risk factor studies looking at non-White populations and to that end, this is a very large and well-done analysis looking at environmental factors among Hispanic patients with IBD.”
He added that, while most studies have just compared factors between cases and controls, “this is an interesting examination of the impact of such factors on age of onset.”
Dr. Ananthakrishnan stressed, however, that further work is needed to expand on these findings.” The addition of a control group would help determine how these factors actually modify disease risk. It is also intriguing that environmental factors more strongly predict age of onset than genetic risk. That only highlights the fact that IBD is in large part an environmentally influenced disease, suggesting there is exciting opportunity for environmental modification to address disease onset.”
Offering another outsider’s perspective, Manasi Agrawal, MD, MS, an assistant professor of medicine at Icahn School of Medicine at Mount Sinai in New York City and not a participant in the study, agreed that the findings highlight the contribution of early life and childhood environmental factors to IBD risk relative to genetic variants. “The relative importance of the environment compared to genetic risk toward IBD, timing of exposure, and impact on age at IBD diagnosis is a novel and important finding. These data will help contextualize how we communicate disease risk and potential prevention approaches.”
She added that future research should measure various exposures, such as pollutants in preclinical biological samples. “Mechanistic data on their downstream effects are needed to understand IBD pathogenesis and develop prevention efforts.”
According to the authors, theirs is the first study of its kind to examine the contribution of cumulative environmental factors, age-dependent exposures, and genetic predisposition to age of IBD diagnosis in a diverse IBD cohort.
The authors listed no specific funding for this study and had no conflicts of interest to declare. Dr. Ananthakrishnan and Dr. Agrawal had no relevant competing interests.

a large study of IBD patients reported.
Published in Clinical Gastroenterology and Hepatology , the study found that environment influences the onset of both ulcerative colitis (UC) and Crohn’s disease (CD), and exposures typical in Western society lower the age of diagnosis. These factors include birth in a developed nation, delivery by C-section, and more bathrooms in the home, according to Oriana M. Damas, MD, MSCTI, an associate professor of clinical medicine at the University of Miami Miller School of Medicine in Florida and colleagues.
Environmental factors explained 21% of the variance in age of CD diagnosis and 39% of the variance in age of UC diagnosis. In models incorporating both genetic and environmental risk scores, the environment was the only significant factor associated with younger age of IBD diagnosis in all groups.
Several epidemiologic studies have examined environmental culprits in IBD, and others have examined genetic risk factors, Dr. Damas said in an interview. “But we had not seen any studies that examined the influence of both [of] these on age of IBD development.” Her group’s working hypothesis that environment would have a greater effect than genetics was borne out.
“Additionally, very few studies have examined the contribution of genetics or environmental factors in Hispanic individuals, and our study examined the contribution of these factors in this understudied population,” she added.
According to Dr. Damas, the findings’ most immediate clinical relevance is for counseling people with a family history of IBD. “I think it’s important for concerned patients to know that IBD is not solely genetic and that several environmental factors can shape disease risk to a greater extent than genetic predisposition,” she said
Westernization is increasingly considered a contributor to the global increase in IBD, which has been diagnosed in an estimated 2.39 million Americans .

FROM CLINICAL GASTROENTEROLOGY AND HEPATOLOGY
Screen for Urinary Incontinence and Manage It in Primary Care
An estimated 25 million adult Americans experience temporary or chronic urinary incontinence.
Although urinary incontinence can occur in both women and men at any age, it is more common in women over age 50. According to Rise for Health, a national survey-based research study on bladder health, up to 40% of girls and women experience urinary problems and it may be as high as 50% or 60%.
“The main known predictors of urinary incontinence are age, obesity, diabetes, and pregnancy and childbirth,” said internist Joan M. Neuner MD, MPH, a professor of women’s health at Medical College of Wisconsin, Milwaukee.
Other causes are urinary tract infections, pelvic surgery, and in men, of course, prostate problems. Medications such as antihypertensives and antidepressants can promote urinary incontinence. Inexplicably, smokers seem to be at higher risk. Childbearing is a prime reason women are at greater risk. “While C-section can be protective against many pelvic floor issues, vaginal delivery, particularly forceps assisted, increases the risk for urinary incontinence,” said Sarah Friedman, MD, director of the Division of Urogynecology at Staten Island University Hospital, New York City.
Urinary incontinence is underrecognized and undertreated in primary care and may not get enough emphasis in medical schools. Dr. Neuner recently coauthored a small pilot study on developing a primary care pathway to manage urinary incontinence. It suggested that a streamlined paradigm from identification and patient self-care through basic medical care and specialty referral might assist primary care providers as first-line providers in urinary incontinence.
Urinary incontinence’s impact on quality of life should not be underestimated. “It depends on severity, but people may limit their physical activities and social activities, including work, going out with friends, and sexual activity, which can in turn increase loneliness and depression,” Dr. Neuner said in an interview. “Incontinence products like pads and adult diapers are costly and often not covered by insurance.”
In fact, urinary incontinence costs US men and women more than $20 billion per year, mostly for management supplies such as pads and laundry.
Primary Care
While primary care practitioners are well positioned to manage urinary incontinence, the majority of patients remain untreated.
The current stepwise approach should start with a knowledge of basic micturition physiology to identify the incontinence type before selecting treatment, said Khaled A. Imam, MD, CMD, a geriatrician at Corewell Health William Beaumont University Hospital in Royal Oak, Michigan. “More important, this working knowledge can prevent the prescription of an inappropriate treatment or drug, thus preventing many adverse effects,”
According to Dr. Imam, urinary incontinence occurs “because the outlet is open when it should be closed, the outlet is closed when it should be open, the detrusor fails to contract, or the detrusor contracts when it should not.”
There are five main types of incontinence: transient, detrusor overactivity (urge), stress, overflow, and functional. The primary care evaluation of urinary incontinence should include history taking, physical examination, post-voiding residual volume measurement, urinalysis, and urine culture, according to Dr. Imam. “The physical examination should include a urine stress test, abdominal examination, pelvic examination in female patients, rectal examination, and neurologic evaluation.”
Screening
“I am always careful before recommending additional screening that hasn’t been backed by a large screening study. Incontinence has not,” said Dr. Neuner. “However, at most preventive visits, PC [primary care] doctors do a review of systems that includes common symptoms. And so if a PC is currently asking a more generic question like ‘any problems with urine?’ I recommend they replace it with the more specific ‘during the last 3 months, have you leaked any urine, even a small amount?’ ”
Added Kathryn E. Flynn, PhD, a professor of medicine at Medical College of Wisconsin and Dr. Neuner’s coauthor on the primary care pilot study: “Routine screening for urinary incontinence in primary care makes a lot of sense because most older women visit a primary care provider regularly, but they often don’t want to bring the topic up to their provider. When providers routinely screen, it can reduce that barrier to disclosure.“
Treatment
For many women, DIY measures such as losing weight, restricting badder irritants such as caffeine or alcohol, scheduled or double voiding, and at-home Kegel exercises are not enough. Fortunately, treatment options are expanding.
“Nonpharmacologic interventions such as pelvic physical therapy can strengthen the pelvic floor muscles and improve incontinence as long as the muscle strength is maintained,” said Dr. Friedman. “Some procedural or surgical effects last long term and some are shorter acting and need to be repeated over time, but a medication’s effect on bladder function lasts only as long as you take it.”
Strengthening pelvic floor muscles. Solutions for stress incontinence – leakage during coughing, sneezing, lifting, or jumping – aim to hold the urethra closed in the face of increased pressure. “Strengthening the pelvic floor muscles can help hold the urethra closed, but many of us do not know how to contract our pelvic floor muscles correctly,” said Heidi Brown, MD, MAS, a clinician researcher at Kaiser Permanente Southern California and a urogynecologist at Kaiser Permanente San Diego Medical Center. “Working with a pelvic floor therapist is not an option for many busy people, so devices that can be used at home to help women confirm they’re contracting their muscles correctly and remind them to do their exercises are becoming more popular.”
These trainers include external thigh exercisers and vaginal Kegel balls or weights. Kegel chairs that electromagnetically stimulate pelvic muscle contractions are another option, if more expensive. Some deliver pelvic therapy in clinic sessions, but there are several portable versions for home use available online.
According to Dr. Neuner, “pelvic exercises can reduce incontinence by 50% or more. “Some women stay completely dry with them but many women will need help to do these and I usually recommend a referral to a pelvic floor physical therapist or someone with extensive experience.”
Drugs. Overactive bladder, or urge urinary incontinence, leads to leakage because the bladder muscle contracts strongly at inappropriate times. Anticholinergics/antimuscarinics such as oxybutynin (Oxytrol, Ditropan) have been used for decades to control these spasms by relaxing the bladder muscle. Because of recent concerns about their association with cognitive impairment after long-term use, these agents are now being used more cautiously, said Dr. Brown. “A newer class of medication, the beta-3-adrenergic agonists, has not been shown to have that association with cognitive impairment and this class is now being used more frequently to treat overactive bladder.”
This class includes the beta-3-adrenergic agonists vibegron (Gemtesa) and mirabegron (Myrbetriq), which a recent Japanese crossover study found to be comparably effective in women with overactive bladder.
“While they have fewer safety concerns, these newer agents can be costly or may require lots of insurance paperwork, and while I hope that will improve soon, it hasn’t yet,” said Dr. Neuner.
Another pharmacologic option is botulinum A toxin (Botox). Injected into the bladder, this neurotoxin can ease urgency and frequency by relaxing the bladder muscle, added Dr. Friedman.
In some cases combination pharmacotherapy may be advisable.
Surgery. Mid-urethral slings are still considered the preferred option for stress urinary incontinence because they are minimally invasive, safe, and very effective, said Dr. Brown. “Single-incisions slings are an emerging treatment for stress incontinence, because they require one incision instead of three, but their effectiveness has not been proven as robustly as that of the traditional mid-urethral slings,” Dr. Brown said.
Urethral bulking. Bulking can reduce incontinence caused by straining as in defecation by thickening the wall of the urethra. This procedure uses a needle to inject a filler material such as collagen. “These injections are gaining more popularity as research uncovers filler materials that are more durable and with fewer potential complications,” Dr. Brown said.
Neuromodulation. This technique works to reprogram communication between the nerves and the bladder. While conventional therapy worked by relaxing the bladder muscle itself, newer approaches target the nerve that controls the muscle. This can be done at home with gentle, acupuncture-like electric stimulation of the S3 sacral nerve.
“Traditional methods of stimulating the S3 nerve involved placing a needle in the ankle and delivering electrical stimulation via that needle in the doctor’s office, or placing a wire in the nerve near the spine and implanting a pacemaker to deliver electrical stimulation,” Dr. Brown explained. “There are now emerging therapies that implant a device in the ankle to allow electrical stimulation of the S3 nerve in the home, providing a minimally invasive option that does not require weekly trips to the office.”
InterStim is a neural pacemaker that is inserted into the fat of the buttocks and patient controlled by a small handheld external device.
Biofeedback is a technique works for some. A patch applied to the skin over the bladder and urethra area and connected to an external monitor allows patients to see the bladder muscle contracting and teaches them to control spasms and prevent leaks.
Dr. Neuner advises primary care doctors to connect with a local incontinence expert and refer patients to a specialist early on if their condition isn’t improving. “There are both surgical and nonsurgical treatments that only those specialists can give and that can be more effective if given before incontinence is severe — or before the patient has been so frustrated with other treatments that she doesn’t want to try anything else.”
When discussing potential outcomes with patients, Dr. Friedman’s advice is to explain that each management option has different success rates. “Patients need to know that urinary incontinence is a very common condition, but it is not a condition you need to live with. There are many treatments available, all with the goal of improving quality of life.”
The primary care pathway pilot study was supported by the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health. Study authors Dr. Neuner and Dr. Flynn disclosed no relevant conflicts of interest. Dr. Friedman, Dr. Imam, and Dr. Brown disclosed no relevant conflicts of interest.

An estimated 25 million adult Americans experience temporary or chronic urinary incontinence.
Although urinary incontinence can occur in both women and men at any age, it is more common in women over age 50. According to Rise for Health, a national survey-based research study on bladder health, up to 40% of girls and women experience urinary problems and it may be as high as 50% or 60%.
“The main known predictors of urinary incontinence are age, obesity, diabetes, and pregnancy and childbirth,” said internist Joan M. Neuner MD, MPH, a professor of women’s health at Medical College of Wisconsin, Milwaukee.
Other causes are urinary tract infections, pelvic surgery, and in men, of course, prostate problems. Medications such as antihypertensives and antidepressants can promote urinary incontinence. Inexplicably, smokers seem to be at higher risk. Childbearing is a prime reason women are at greater risk. “While C-section can be protective against many pelvic floor issues, vaginal delivery, particularly forceps assisted, increases the risk for urinary incontinence,” said Sarah Friedman, MD, director of the Division of Urogynecology at Staten Island University Hospital, New York City.
Urinary incontinence is underrecognized and undertreated in primary care and may not get enough emphasis in medical schools. Dr. Neuner recently coauthored a small pilot study on developing a primary care pathway to manage urinary incontinence. It suggested that a streamlined paradigm from identification and patient self-care through basic medical care and specialty referral might assist primary care providers as first-line providers in urinary incontinence.
Urinary incontinence’s impact on quality of life should not be underestimated. “It depends on severity, but people may limit their physical activities and social activities, including work, going out with friends, and sexual activity, which can in turn increase loneliness and depression,” Dr. Neuner said in an interview. “Incontinence products like pads and adult diapers are costly and often not covered by insurance.”
In fact, urinary incontinence costs US men and women more than $20 billion per year, mostly for management supplies such as pads and laundry.
Primary Care
While primary care practitioners are well positioned to manage urinary incontinence, the majority of patients remain untreated.
The current stepwise approach should start with a knowledge of basic micturition physiology to identify the incontinence type before selecting treatment, said Khaled A. Imam, MD, CMD, a geriatrician at Corewell Health William Beaumont University Hospital in Royal Oak, Michigan. “More important, this working knowledge can prevent the prescription of an inappropriate treatment or drug, thus preventing many adverse effects,”
According to Dr. Imam, urinary incontinence occurs “because the outlet is open when it should be closed, the outlet is closed when it should be open, the detrusor fails to contract, or the detrusor contracts when it should not.”
There are five main types of incontinence: transient, detrusor overactivity (urge), stress, overflow, and functional. The primary care evaluation of urinary incontinence should include history taking, physical examination, post-voiding residual volume measurement, urinalysis, and urine culture, according to Dr. Imam. “The physical examination should include a urine stress test, abdominal examination, pelvic examination in female patients, rectal examination, and neurologic evaluation.”
Screening
“I am always careful before recommending additional screening that hasn’t been backed by a large screening study. Incontinence has not,” said Dr. Neuner. “However, at most preventive visits, PC [primary care] doctors do a review of systems that includes common symptoms. And so if a PC is currently asking a more generic question like ‘any problems with urine?’ I recommend they replace it with the more specific ‘during the last 3 months, have you leaked any urine, even a small amount?’ ”
Added Kathryn E. Flynn, PhD, a professor of medicine at Medical College of Wisconsin and Dr. Neuner’s coauthor on the primary care pilot study: “Routine screening for urinary incontinence in primary care makes a lot of sense because most older women visit a primary care provider regularly, but they often don’t want to bring the topic up to their provider. When providers routinely screen, it can reduce that barrier to disclosure.“
Treatment
For many women, DIY measures such as losing weight, restricting badder irritants such as caffeine or alcohol, scheduled or double voiding, and at-home Kegel exercises are not enough. Fortunately, treatment options are expanding.
“Nonpharmacologic interventions such as pelvic physical therapy can strengthen the pelvic floor muscles and improve incontinence as long as the muscle strength is maintained,” said Dr. Friedman. “Some procedural or surgical effects last long term and some are shorter acting and need to be repeated over time, but a medication’s effect on bladder function lasts only as long as you take it.”
Strengthening pelvic floor muscles. Solutions for stress incontinence – leakage during coughing, sneezing, lifting, or jumping – aim to hold the urethra closed in the face of increased pressure. “Strengthening the pelvic floor muscles can help hold the urethra closed, but many of us do not know how to contract our pelvic floor muscles correctly,” said Heidi Brown, MD, MAS, a clinician researcher at Kaiser Permanente Southern California and a urogynecologist at Kaiser Permanente San Diego Medical Center. “Working with a pelvic floor therapist is not an option for many busy people, so devices that can be used at home to help women confirm they’re contracting their muscles correctly and remind them to do their exercises are becoming more popular.”
These trainers include external thigh exercisers and vaginal Kegel balls or weights. Kegel chairs that electromagnetically stimulate pelvic muscle contractions are another option, if more expensive. Some deliver pelvic therapy in clinic sessions, but there are several portable versions for home use available online.
According to Dr. Neuner, “pelvic exercises can reduce incontinence by 50% or more. “Some women stay completely dry with them but many women will need help to do these and I usually recommend a referral to a pelvic floor physical therapist or someone with extensive experience.”
Drugs. Overactive bladder, or urge urinary incontinence, leads to leakage because the bladder muscle contracts strongly at inappropriate times. Anticholinergics/antimuscarinics such as oxybutynin (Oxytrol, Ditropan) have been used for decades to control these spasms by relaxing the bladder muscle. Because of recent concerns about their association with cognitive impairment after long-term use, these agents are now being used more cautiously, said Dr. Brown. “A newer class of medication, the beta-3-adrenergic agonists, has not been shown to have that association with cognitive impairment and this class is now being used more frequently to treat overactive bladder.”
This class includes the beta-3-adrenergic agonists vibegron (Gemtesa) and mirabegron (Myrbetriq), which a recent Japanese crossover study found to be comparably effective in women with overactive bladder.
“While they have fewer safety concerns, these newer agents can be costly or may require lots of insurance paperwork, and while I hope that will improve soon, it hasn’t yet,” said Dr. Neuner.
Another pharmacologic option is botulinum A toxin (Botox). Injected into the bladder, this neurotoxin can ease urgency and frequency by relaxing the bladder muscle, added Dr. Friedman.
In some cases combination pharmacotherapy may be advisable.
Surgery. Mid-urethral slings are still considered the preferred option for stress urinary incontinence because they are minimally invasive, safe, and very effective, said Dr. Brown. “Single-incisions slings are an emerging treatment for stress incontinence, because they require one incision instead of three, but their effectiveness has not been proven as robustly as that of the traditional mid-urethral slings,” Dr. Brown said.
Urethral bulking. Bulking can reduce incontinence caused by straining as in defecation by thickening the wall of the urethra. This procedure uses a needle to inject a filler material such as collagen. “These injections are gaining more popularity as research uncovers filler materials that are more durable and with fewer potential complications,” Dr. Brown said.
Neuromodulation. This technique works to reprogram communication between the nerves and the bladder. While conventional therapy worked by relaxing the bladder muscle itself, newer approaches target the nerve that controls the muscle. This can be done at home with gentle, acupuncture-like electric stimulation of the S3 sacral nerve.
“Traditional methods of stimulating the S3 nerve involved placing a needle in the ankle and delivering electrical stimulation via that needle in the doctor’s office, or placing a wire in the nerve near the spine and implanting a pacemaker to deliver electrical stimulation,” Dr. Brown explained. “There are now emerging therapies that implant a device in the ankle to allow electrical stimulation of the S3 nerve in the home, providing a minimally invasive option that does not require weekly trips to the office.”
InterStim is a neural pacemaker that is inserted into the fat of the buttocks and patient controlled by a small handheld external device.
Biofeedback is a technique works for some. A patch applied to the skin over the bladder and urethra area and connected to an external monitor allows patients to see the bladder muscle contracting and teaches them to control spasms and prevent leaks.
Dr. Neuner advises primary care doctors to connect with a local incontinence expert and refer patients to a specialist early on if their condition isn’t improving. “There are both surgical and nonsurgical treatments that only those specialists can give and that can be more effective if given before incontinence is severe — or before the patient has been so frustrated with other treatments that she doesn’t want to try anything else.”
