Less CPAP time linked to exacerbation in COPD/OSA overlap syndrome
and all‐cause mortality, according to a retrospective cohort study.
“These factors should be taken into account when considering the management and prognosis of these patients,” the researchers said in the Clinical Respiratory Journal.
Prior studies have found that patients with COPD and OSA – that is, with overlap syndrome – “have a substantially greater risk of morbidity and mortality, compared to those with either COPD or OSA alone,” said Philippe E. Jaoude, MD, and Ali A. El Solh, MD, both of the Veterans Affairs Western New York Healthcare System in Buffalo and the University at Buffalo.
To identify factors associated with COPD exacerbation and all‐cause mortality in patients with overlap syndrome, Dr. Jaoude and Dr. El Solh reviewed the electronic health records of patients with simultaneous COPD and OSA. They compared patients with overlap syndrome who had an acute exacerbation of COPD during a 42-month period with a control group of patients with overlap syndrome who did not have exacerbations during that time. Patients with exacerbations and controls were matched 1:1 by age and body mass index.
Eligible patients were aged 42-90 years, had objectively confirmed COPD, and had documented OSA by in-laboratory polysomnography (that is, at least five obstructive apneas and hypopneas per hour). The investigators defined a COPD exacerbation as a sustained worsening of a patient’s respiratory condition that warranted additional treatment.
Of 225 eligible patients, 92 had at least one COPD exacerbation between March 2014 and September 2017. Patients with COPD exacerbation and controls had a mean age of about 68 years. The group of patients with exacerbation had a higher percentage of active smokers (21% vs. 9%) and had poorer lung function (mean forced expiratory volume in 1 second percent predicted: 55.2% vs. 64.5%).
“Although the rate of CPAP adherence between the two groups was not significantly different, the average time of CPAP use was significantly higher in patients with no recorded exacerbation,” the researchers reported – 285.4 min/night versus 238.2 min/night.
In all, 146 patients (79.4%) survived, and 38 patients (20.6%) died during the study period. The crude mortality rate was significantly higher in the group with COPD exacerbations (14% vs. 7%).
“Multivariate logistic regression analysis identified the independent risk factors associated with COPD exacerbations as active smoking, worse airflow limitation, and lower CPAP utilization,” they said. “As for all-cause mortality, a higher burden of comorbidities, worse airflow limitation, and lower time of CPAP use were independently associated with poor outcome.”
The researchers noted that they cannot rule out the possibility that patients who were adherent to CPAP were systematically different from those who were not.
The authors had no conflicts of interest.

New study confirms rise in U.S. suicide rates, particularly in rural areas
County-by-county analysis cites links to higher density of gun shops, other factors
Suicide rates in the United States climbed from 1999 to 2016, a new cross-sectional study found, and the increases were highest in rural areas.
“These findings are consistent with previous studies demonstrating higher and more rapidly increasing suicide rates in rural areas and are of considerable interest in light of the work by [Anne] Case and [Angus] Deaton,” wrote Danielle L. Steelesmith, PhD, and associates. “While increasing rates of suicide are well documented, little is known about contextual factors associated with county-level suicide rates.” The findings appear in JAMA Network Open.
To examine those contextual factors, Dr. Steelesmith, of the department of psychiatry and behavioral health at the Ohio State University, Columbus, and associates analyzed county-by-county suicide statistics from 1999 to 2016 for adults aged 25-64 years, noting that they “focused on this age range because most studies on mortality trends have focused on this age range.”
The researchers developed 3-year suicide averages for counties for rate “stabilization” purposes. They placed the counties into four categories (large metropolitan, small metropolitan, micropolitan, and rural), and used various data sources to gather various types of statistics about the communities.
Most of those who died by suicide were men (77%), and most (51%) were aged 45-64 years. The median suicide rate per county rose from 15 per 100,000 (1999-2001) to 21 per 100,000 (2014-2016), reported Dr. Steelesmith and associates.
Rural counties only made up 2% of the suicides, compared with 81% in large and small metropolitan counties, but suicide rates were “increasing most rapidly in rural areas, although all county types saw increases during the period studied,” Dr. Steelesmith and associates wrote.
They added that “counties with the highest excess risk of suicide tended to be in Western states (e.g., Colorado, New Mexico, Utah, and Wyoming), Appalachia (e.g., Kentucky, Virginia, and West Virginia), and the Ozarks (e.g., Arkansas and Missouri).”
In addition to the connections between increasing suicide rates, living in a rural area, and a higher density of gun shops, the researchers cited other contextual factors. Among those factors were higher median age and higher percentages of non-Hispanic whites, numbers of residents without health insurance, and veterans. They also found links between higher suicide rates and worse numbers on indexes designed to measure social capital; social fragmentation; and deprivation, a measure encompassing lower education, employment levels, and income.
“Long-term and persistent poverty appears to be more entrenched and economic opportunities more constrained in rural areas,” Dr. Steelesmith and associates wrote. “Greater social isolation, challenges related to transportation and interpersonal communication, and associated difficulties accessing health and mental health services likely contribute to the disproportionate association of deprivation with suicide in rural counties.”
Dr. Steelesmith and associates cited several limitations. One key limitation is that, because the study looked only at adults aged 25-64 years, the results might not be generalizable to youth or elderly adults.
No study funding was reported. One study author reported serving on the scientific advisory board of Clarigent Health and receiving grant support from the National Institute of Mental Health outside of the submitted work. No other disclosures were reported.

Guideline: Blood CO2 can be used to screen for OHS
A blood test for elevated carbon dioxide may be used in screening adults for obesity hypoventilation syndrome, according to new guidelines.
Obese adults with sleep-disordered breathing and increased blood carbon dioxide levels during the day are likely to have obesity hypoventilation syndrome (OHS), a result of shallow or slow breathing that can lead to respiratory failure, heart failure, pulmonary hypertension, and death. Pulmonologists and sleep specialists may be the first to see and diagnose patients with OHS in the outpatient setting, while other cases are diagnosed in the hospital when patients present with hypercapnic respiratory failure.
Screening for OHS usually involves measuring arterial blood gases, which is not standard practice in outpatient clinics. Patients often remain undiagnosed and untreated until late in the course of the disease, according to the American Thoracic Society, which in August published a new diagnosis and management guideline aiming to boost early diagnosis and reduce variability in treatment (Am J Respir Crit Care Med. 2019;200:3,e6–e24).
The guideline authors, led by Babak Mokhlesi, MD, of the University of Chicago, recommend a simpler screening method – measuring serum bicarbonate only – to rule out OHS in obese patients with nighttime breathing problems.
Serum bicarbonate should be measured in obese patients with sleep-disordered breathing and a low likelihood of OHS, Dr. Mokhlesi and colleagues recommend in the guideline. If serum bicarbonate is below 27 mmol/L, it is not necessary to conduct further testing as the patient is unlikely to have OHS.
In patients whose serum bicarbonate is higher than 27 mmol/L, or who are strongly suspected of having OHS at presentation because of severe obesity or other symptoms, arterial blood gases should be measured and a sleep study conducted. The guideline authors said that there is insufficient evidence to recommend that pulse oximetry be used in the diagnostic pathway for OHS.
First-line treatment for stable, ambulatory patients with OHS should be positive airway pressure during sleep, rather than noninvasive ventilation, Dr. Mokhlesi and colleagues concluded. For patients with comorbid obstructive sleep apnea – as many as 70% of OHS patients also have OSA – the first-line treatment should be continuous positive airway pressure (CPAP) at night, the guideline states.
Patients hospitalized with respiratory failure and suspected of having OHS should be discharged with noninvasive ventilation until diagnostic procedures can be performed, along with PAP titration in a sleep lab.
In patients initially treated with CPAP who remain symptomatic or whose blood carbon dioxide does not improve, noninvasive ventilation can be tried, the guidelines say. Finally, patients diagnosed with OHS should be guided to weight loss interventions with the aim of reducing body weight by 25%-30%. This can include referral for bariatric surgery in patients without contraindications.
Dr. Mokhlesi and colleagues acknowledged that all of the recommendations contained in the guideline are classed as “conditional,” based on the quality of evidence assessed.
The American Thoracic Society funded the study. Dr. Mokhlesi and 7 coauthors disclosed financial conflicts of interest, while an additional 13 coauthors had none. Disclosures can be found on the AJRCCM website.

Vape lung disease cases exceed 400, 3 dead
Vitamin E acetate is one possible culprit in the mysterious vaping-associated lung disease that has killed three patients, sickened 450, and baffled clinicians and investigators all summer.
Another death may be linked to the disorder, officials said during a joint press briefing held by the Centers for Disease Control and Prevention and the Food and Drug Administration. In all, 450 potential cases have been reported and e-cigarette use confirmed in 215. Cases have occurred in 33 states and one territory. A total of 84% of the patients reported having used tetrahydrocannabinol (THC) products in e-cigarette devices.
A preliminary report on the situation by Jennifer Layden, MD, of the department of public health in Illinois and colleagues – including a preliminary case definition – was simultaneously released in the New England Journal of Medicine (2019 Sep 6. doi: 10.1056/NEJMoa1911614).
No single device or substance was common to all the cases, leading officials to issue a blanket warning against e-cigarettes, especially those containing THC.
“We believe a chemical exposure is likely related, but more information is needed to determine what substances. Some labs have identified vitamin E acetate in some samples,” said Dana Meaney-Delman, MD, MPH, incident manager, CDC 2019 Lung Injury Response. “Continued investigation is needed to identify the risk associated with a specific product or substance.”
Besides vitamin E acetate, federal labs are looking at other cannabinoids, cutting agents, diluting agents, pesticides, opioids, and toxins.
Officials also issued a general warning about the products. Youths, young people, and pregnant women should never use e-cigarettes, they cautioned, and no one should buy them from a noncertified source, a street vendor, or a social contact. Even cartridges originally obtained from a certified source should never have been altered in any way.
Dr. Layden and colleagues reported that bilateral lung infiltrates was characterized in 98% of the 53 patients hospitalized with the recently reported e-cigarette–induced lung injury. Nonspecific constitutional symptoms, including fever, chills, weight loss, and fatigue, were present in all of the patients.
Patients may show some symptoms days or even weeks before acute respiratory failure develops, and many had sought medical help before that. All presented with bilateral lung infiltrates, part of an evolving case definition. Many complained of nonspecific constitutional symptoms, including fever, chills, gastrointestinal symptoms, and weight loss. Of the patients who underwent bronchoscopy, many were diagnosed as having lipoid pneumonia, a rare condition characterized by lipid-laden macrophages.
“We don’t know the significance of the lipid-containing macrophages, and we don’t know if the lipids are endogenous or exogenous,” Dr. Meaney-Delman said.
The incidence of such cases appears to be rising rapidly, Dr. Layden noted. An epidemiologic review of cases in Illinois found that the mean monthly rate of visits related to severe respiratory illness in June-August was twice that observed during the same months last year.

The incidence of such cases appears to be rising rapidly, Dr. Layden noted. An epidemiologic review of cases in Illinois found that the mean monthly rate of visits related to severe respiratory illness in June-August was twice that observed during the same months last year.

Vitamin E acetate is one possible culprit in the mysterious vaping-associated lung disease that has killed three patients, sickened 450, and baffled clinicians and investigators all summer.
Another death may be linked to the disorder, officials said during a joint press briefing held by the Centers for Disease Control and Prevention and the Food and Drug Administration. In all, 450 potential cases have been reported and e-cigarette use confirmed in 215. Cases have occurred in 33 states and one territory. A total of 84% of the patients reported having used tetrahydrocannabinol (THC) products in e-cigarette devices.
A preliminary report on the situation by Jennifer Layden, MD, of the department of public health in Illinois and colleagues – including a preliminary case definition – was simultaneously released in the New England Journal of Medicine (2019 Sep 6. doi: 10.1056/NEJMoa1911614).
No single device or substance was common to all the cases, leading officials to issue a blanket warning against e-cigarettes, especially those containing THC.
“We believe a chemical exposure is likely related, but more information is needed to determine what substances. Some labs have identified vitamin E acetate in some samples,” said Dana Meaney-Delman, MD, MPH, incident manager, CDC 2019 Lung Injury Response. “Continued investigation is needed to identify the risk associated with a specific product or substance.”
Besides vitamin E acetate, federal labs are looking at other cannabinoids, cutting agents, diluting agents, pesticides, opioids, and toxins.
Officials also issued a general warning about the products. Youths, young people, and pregnant women should never use e-cigarettes, they cautioned, and no one should buy them from a noncertified source, a street vendor, or a social contact. Even cartridges originally obtained from a certified source should never have been altered in any way.
Dr. Layden and colleagues reported that bilateral lung infiltrates was characterized in 98% of the 53 patients hospitalized with the recently reported e-cigarette–induced lung injury. Nonspecific constitutional symptoms, including fever, chills, weight loss, and fatigue, were present in all of the patients.
Patients may show some symptoms days or even weeks before acute respiratory failure develops, and many had sought medical help before that. All presented with bilateral lung infiltrates, part of an evolving case definition. Many complained of nonspecific constitutional symptoms, including fever, chills, gastrointestinal symptoms, and weight loss. Of the patients who underwent bronchoscopy, many were diagnosed as having lipoid pneumonia, a rare condition characterized by lipid-laden macrophages.
“We don’t know the significance of the lipid-containing macrophages, and we don’t know if the lipids are endogenous or exogenous,” Dr. Meaney-Delman said.

NICE issues recommendation for dapagliflozin-insulin therapy in type 1 diabetes
The inadequately controlled by insulin alone.
In a review of clinical trials, NICE found that dapagliflozin plus insulin conferred small benefits in hemoglobin A1c, weight loss, and quality of life, compared with insulin alone. These benefits translated to a reduced risk of long-term complications over the lifetime of the patient.
In the new NICE guideline, dual treatment with dapagliflozin and insulin in adults with type 1 diabetes and a body mass index greater than 27 kg/m2 is recommended only when they are receiving insulin doses of more than 0.5 units/kg per day; have undergone an evidence-based, quality-assured education program; and are supervised by a physician specializing in endocrinology and diabetes.
Hemoglobin A1c levels should be assessed after 6 months and at regular intervals after that; if glycemic control is not improved, dapagliflozin should be stopped, as there is an increased risk of diabetic ketoacidosis.

Battling hospitalist burnout
Higher salaries are not sufficient
Hospitalist Rahul C. Borsadia, MD, had been working with Orlando Health Inpatient Medicine Group since the year of its founding in 2011.
The salaries of the practice’s physicians back then were based on relative value units (RVU) – the more patients that physicians saw, the higher their salaries. But a problem arose, Dr. Borsadia said. Physicians were trying to squeeze in two dozen or more patients a day “in a practice that is modeled for quality.”
“By the time the end of the day comes, it’s 9 or 10 p.m. and you are leaving but coming back at 6:30 the next morning. So, lack of sleep, more patients, striving to earn that higher salary,” he said. “The desire to perform quality work with that kind of patient load was not fulfilled and that lead to dissatisfaction and stress, which lead to irritation and exodus from the group.”
Three years ago, the practice transitioned to a throughput process with a census limit of 18 patients or less, without an RVU system, but with salary incentives based on patient satisfaction, billing, and documentation.
“We’ve not had anybody leave the hospital because of burnout or dissatisfaction” since the new system was put into place, Dr. Borsadia said. “Less burnout means more people are happy.”
Although symptoms of burnout still seem to be rampant across hospital medicine, hospitalists are putting potential solutions into place. And – sometimes – they are making progress, through tweaks in schedules and responsibilities, incentives suited to different goals, and better communication.
Scheduling problems
The need for continuing efforts to improve the work experience for hospitalists is apparent, said Henry Michtalik, MD, MPH, MHS, assistant professor of general internal medicine at Johns Hopkins, Baltimore, who led a workshop on the topic at the 2019 Annual Conference of the Society of Hospital Medicine (HM19).
A 2016 survey of academic general internal medicine clinicians – including about 600 hospitalists and outpatient physicians – found that 67% reported high stress, 38% said they were “burned out,” 50% said they felt they had “low control” over their work, and 60% said they felt high documentation pressures. Still, 68% said they were satisfied with the values of their departments.
Hospitalists surveyed were actually less likely to say they were burned out, compared with outpatient internists – 52%, compared with 55% – but they were more likely to score low on a scale measuring personal accomplishments, compared with the outpatient clinicians – 20% to 10%. The survey found no significant difference between the two groups in depression or suicidality. But with 40% reporting depression and 10% reporting thoughts of suicide, the numbers virtually cry out for solutions.
Hospitalists in the HM19 workshop, as in other sessions at the Annual Conference, questioned whether the standard 7-days-on, 7-days-off work schedule – seven 12-hour shifts followed by 7 days off – allows hospitalists to pair their works lives with their personal lives in a sustainable way. They described the way that the stress and fatigue of such an intense work period bleeds into the days off that follow after it.
“By the end of seven 12’s, they’re bleary eyed, they’re upset, they go home (for) 2 days of washout before they even start to enjoy whatever life they have left,” said Jonathan Martin, MD, director of medicine at Cumberland Medical Center in Crossville, Tenn. “It’s hard to get hospitalists to buy in, which increases their dissatisfaction.”
Dr. Michtalik had a similar perspective.
“You just shut the rest of your life down completely for those 7 days and then, on your 7 days off, you’ve scheduled your life,” he said. “But that last off day – day number 7 – you feel that pit in your stomach, that the streak is coming.” He joked that the feeling was similar to the dread inspired by the phrase “winter is coming” in the popular HBO series “Game of Thrones.”
Systematic reviews of the literature have found that it’s mostly changes at the organization level – rather than changes that an individual physician makes on his or her own – that tend to make significant differences. Changes to structure, communication, and scheduling tend to work better than working on mindfulness, education, or trying to improve resilience, Dr. Michtalik said.
In one study discussed at the HM19 workshop, researchers compared a schedule in which an intensivist works in-house for 7 days, with home call at night, to a schedule in which the intensivist is completely off at night, with an in-house intensivist covering the night shift. The schedule in which the intensivist was truly off for the night significantly reduced reports of burnout, while not affecting length of stay or patient-experience outcomes.
Dr. Michtalik said that another study compared 4-week rotations to 2-week rotations for attending physicians. Researchers found that the 2-week version resulted in lower reports of burnout, with readmissions and patient experience unaffected, although they noted that residents tended to prefer 4-week schedules because they felt it resulted in better relationships with the attending physician.
Perhaps the dominant factor in job satisfaction that’s been identified in surveys is how physicians, patients, and administrators relate to one another, Dr. Michtalik said.
“The important concept here is that relationships were really important in driving job satisfaction, whether that be with our colleagues, our patients, or with the staff that you’re working with,” he said. “It’s always easier to decline a consultation or have a bad interaction with someone over the phone than it is if you actually know them or you are communicating face to face. That’s why it’s important to develop these kinds of relationships, which also put a face to what’s going on.”
Beyond salary adjustments
Hospitalists attending the HM19 workshop said they thought that participating in administration committees at their own institutions helps keep hospitalists involved in hospital matters, limiting the effects of burnout and improving workplace satisfaction.
Kevin McAninch, DO, a hospitalist with Central Ohio Primary Care in Westerville, said a shift in work responsibilities has made an improvement at his hospital. There is now an “inpatient support center” – which has a physician and a nurse in an office taking calls from 6 p.m. to 7 a.m., so that rounders can stop taking floor calls during that time.
The system “takes the pressure off our admitters at night and our nurses because they’re not getting floor calls anymore, so they’re just taking care of the admissions from the ER,” he said.
A recurring theme of the discussion was that salary alone seems universally incapable of eradicating feelings of burnout. One hospitalist said that in surveys, higher-paid physicians insist that monetary compensation is their main driver, but still often complain of burnout because they must work extra shifts to earn that higher level of pay.
Instead, burnout and satisfaction indicators tend to have more do to with time, control, and support, Dr. Michtalik noted.
Mangla Gulati, MD, SFHM, chief quality officer at the University of Maryland Medical Center in Baltimore, said that there’s no big secret about what hospitalists want from their places of employment. They want things like getting patients to service faster so they can make diagnoses, making sure patients get the care they need, fixing the problems associated with electronic medical records, and having a work-life “integration.”
“The questions is – how do we get there?” Dr. Gulati wondered. She suggested that hospitalists have to be more assertive and explanatory in their interactions with members of the hospital C-suite.
“I think it’s really important for you to understand or ask your C-suite, ‘Where are you in this whole journey? What is your perception of wellness? Tell me some of the measures of staff wellness,’ ” she said.
If the C-suite says “we have no money” to make improvements, hospitalists must be willing to say, ‘Well, you’re going to have to invest a little bit.’ ” Dr. Gulati said. “What is the ROI (return on investment) on the turnover of a physician? Because when you turn a physician over, you have to recruit and hire new staff.”
Dr. Gulati said that hospitalists should provide C-suite leaders with a detailed walk-through of their actual workflows – what their workdays look like – because “it’s not something they’re familiar with.”
Aside from improving relations with hospital administration, Dr. Gulati suggested creating CME programs for wellness, offering time and funding for physician support meetings, supporting flexibility in work hours, and creating programs specifically to help clinicians with burnout symptoms.
She also touted the benefits of “Schwartz Rounds,” in which several medical disciplines gather to talk about a case that was particularly challenging, clinically complex, and emotionally draining for everyone involved.
At Cumberland Medical Center, Dr. Martin said he has two meetings a month with executives in the hospital’s C-suite. One is with his hospitalist group, TeamHealth, and one is more direct, between himself and hospital administrators. It’s just 2 hours a month, but these conversations have undoubtedly helped, he said, although he cautioned that “the meetings themselves don’t have as much meaning if you aren’t communicating effectively,” meaning hospitalists must understand how the C-suite thinks and learn to speak in terms they understand.
“When I go to the administration now and I say ‘Hey, this is a problem that we’re having. I need your help in solving it,’ the executives are much more likely to respond to me than if they’d never seen me, or only see me rarely,” Dr. Martin said.
As a result, a collaborative approach to such conversations tends to be more effective.
“If you go to the C-suite and say, ‘Here’s our issue, how can you help us?’ – as opposed to telling the administration, ‘This is what I need’ – they are more likely to work with you to generate a solution.”

It’s just 2 hours a month, but these conversations have undoubtedly helped, he said, although he cautioned that “the meetings themselves don’t have as much meaning if you aren’t communicating effectively,” meaning hospitalists must understand how the C-suite thinks and learn to speak in terms they understand.
“When I go to the administration now and I say ‘Hey, this is a problem that we’re having. I need your help in solving it,’ the executives are much more likely to respond to me than if they’d never seen me, or only see me rarely,” Dr. Martin said.
As a result, a collaborative approach to such conversations tends to be more effective.
“If you go to the C-suite and say, ‘Here’s our issue, how can you help us?’ – as opposed to telling the administration, ‘This is what I need’ – they are more likely to work with you to generate a solution.”
Migraines linked to higher risk of dementia
, according to research published online Sept. 4 in the International Journal of Geriatric Psychiatry.
In the Manitoba Study of Health and Aging, a population-based, prospective cohort study, 679 community-dwelling adults with a mean age of 75.9 years were followed for 5 years. Participants screened as cognitively intact at baseline had complete data on migraine history and all covariates at baseline and were assessed for cognitive outcomes 5 years later.
The study showed that a history of migraines was associated with a 2.97-fold greater likelihood of dementia, after adjustment for age, education, and a history of stroke, compared with individuals without a history of migraine. Individuals with Alzheimer’s disease were more than four times more likely to have a history of migraines (odds ratio 4.22).
However, researchers found no significant association between vascular dementia and a history of migraines, either before or after adjusting for confounders but particularly after incorporating a history of stroke into the model.
Lead investigator Suzanne L. Tyas, PhD, associate professor in the School of Public Health and Health Systems at the University of Waterloo, Ont., and coauthors suggested that the association between migraine and dementia was largely driven by the strong association between migraines and Alzheimer’s disease.
“This interpretation is supported by the weaker association for dementia than for Alzheimer’s disease, reflecting a dilution of the association with migraines across all types of dementia including vascular dementia, where a significant association was not found,” the researchers wrote.
The study population was 61.9% female, and no men reporting a history of migraine were diagnosed with dementia. While the study reflected a strong association between migraine and dementia in women, the researchers said they were unable to assess potential gender differences in this association.
Commenting on possible mechanisms behind the association, the authors wrote that there were overlaps underlying the biological mechanisms of migraine and dementia. Vascular risk factors such as diabetes, hypertension, heart attack, and stroke are associated with the development of dementia, and a relationship of these risk factors and migraine also has been seen.
“Many of the mechanisms involved in migraine neurophysiology, such as inflammation and reduced cerebral blood flow, are also underlying causes of dementia,” they wrote. “Repeated activation of these pathways in chronic migraineurs has been shown to cause permanent neurological and vascular damage.”
They also observed that the association could be influenced by genetic factors, as individuals with presenilin-1 mutations, which predispose them to Alzheimer’s disease, are more likely to experience migraines or recurrent headaches.
They suggested their findings could inform preventive strategies and treatments for Alzheimer’s disease, as well as interventions such as earlier screening for cognitive decline in individuals who experience migraines.
The study was funded by Manitoba Health and the National Health Research and Development Program of Health Canada. No conflicts of interest were declared.

Thread lifts making a comeback, but long-term effects remain unclear
SAN DIEGO – The use of threads to improve skin laxity is making a comeback, thanks largely to advances in absorbable sutures.
“Thread lifts were popularized in the 1990s, but I think they were misrepresented as an alternative to a surgical face-lift, which remains the gold standard,” Arisa E. Ortiz, MD, said at the annual Masters of Aesthetics Symposium. “A thread lift is certainly not like a traditional face-lift; it’s much more subtle.”
In the 1990s, clinicians used nonabsorbable sutures for thread lifts, including polypropylene-barbed threads, which caused adverse events ranging from extrusion and migration to thread expulsion, dimpling, granuloma formation, and prolonged pain. As a result, the Food and Drug Administration withdrew its approval of contour thread aesthetic procedures in 2009. Since then, the development of absorbable threads made from polydioxanone (PDO) and poly-
“There are some nice benefits to thread lifts,” said Dr. Ortiz, who is director of laser and cosmetic dermatology at the University of California, San Diego. “You get immediate results, which is always nice for patients, but with tissue tightening using energy-based devices, results are unpredictable and it can take 6 months to see the results. With resorbable sutures, we’re seeing fewer complications, and the amount of lifting is more predictable because you’re physically lifting the tissue. In some cases, threads are able to lift tissue more than energy-based devices. There is minimal recovery, it requires local anesthesia, and it’s less expensive than a surgical face-lift, which can run $10,000-$15,000 or more.”
For skin lifting, clinicians implant threads subcutaneously. When tugged in the opposite direction, the barbs anchor in adipose tissue, increasing tensile strength while suspended in the dermis and overlying tissue. This produces a fibrous adhesion capsule that helps to solidify anchorage of the suture long term. Fibrosis has been shown to increase local collagen production. PDO and PLLA are known collagen stimulants and are postulated to stimulate a long-term benefit in rejuvenation, Dr. Ortiz said, but overall evidence regarding their use in thread lifts is weak.
“Existing studies have a very short follow-up period and there is really no standardized protocol, so we don’t know really know a lot about them yet,” she said. Lana Tong, MD, and Evan A. Rieder, MD, of New York University recently published a systematic review of the literature on the topic (Dermatol Surg. 2019 45[7]:931-40).
PDO is biodegradable by hydrolysis over 4-8 months and is used as absorbable suture material for prolonged tension–bearing areas. “It causes neocollagenesis with a foreign-body reaction,” Dr. Ortiz said. Meanwhile, PLLA is a collagen stimulator used for prolonged volume restoration. “It’s used an aesthetic filler, but a known complication with PLLA injections is the formation of subcutaneous nodules and late onset granulomas,” she said.
Early in 2019, Korean researchers published results of a study that set out to evaluate the collagen-producing effects of powdered PDO injection, compared with PLLA injection, in a murine model (J Cosmet Dermatol. 2019 Feb 27. doi: 10.1111/jocd.12894). “It showed both PDO and PLLA induced granulomatous reactions and collagen formation, but this decreased at 12 weeks,” said Dr. Ortiz, who was not involved with the work. “PDO had slightly more collagen formation than PLLA.”
Indications for thread lifts, she continued, are for jawline lift, cheek enhancement, brow lift, wrinkle reduction, body contouring, acne scarring, and texturing. “Choose patients with good skin quality: not too thick/heavy, and not too thin. Patients with moderate skin sagging are going to better candidates than those with severe skin sagging.”
One type of absorbable suspension suture, the Silhouette InstaLift, is made of polyglycolide/
In terms of adverse events following thread lift procedures, patients usually feel tender for about a week or 2. “They can have some bruising, mostly from the anesthesia,” she said.
To prevent temporary dimpling, Dr. Ortiz undermines with an 18-gauge needle and inserts perpendicular to the skin surface. “Extrusions can still occur,” she said. To prevent this, she pulls on the end and makes sure it’s buried subcutaneously.
Dr. Ortiz reported having financial relationships with numerous pharmaceutical and device companies, though none related to the content of her presentation. She is also cochair of the Masters of Aesthetics symposium.

EXPERT ANALYSIS FROM MOA 2019
#Dermlife and the Burned-out Resident
Dermatologist Dr. Jeffrey Benabio quipped, “The phrase ‘dermatologist burnout’ may seem as oxymoronic as jumbo shrimp, yet both are real.”1 Indeed, dermatologists often self-report as among the happiest specialists both at work and home, according to the annual Medscape Physician Lifestyle and Happiness Report.2 Similarly, others in the medical field may perceive dermatologists as low-stress providers—well-groomed, well-rested rays of sunshine, getting out of work every day at 5:00
Burnout in Dermatology Residents
Burnout is a syndrome of emotional exhaustion, depersonalization, and a sense of reduced personal accomplishment that affects residents of all specialties3; however, there is a paucity of literature on burnout as it relates to dermatology. Although long work hours and schedule volatility have captured the focus of resident burnout conversations, a less discussed set of factors may contribute to dermatology resident burnout, such as increasing patient load, intensifying regulations, and an unrelenting pace of clinic. A recent survey study by Shoimer et al3 found that 61% of 116 participating Canadian dermatology residents cited examinations (including the board certifying examination) as their top stressor, followed by work (27%). Other stressors included family, relationships, finances, pressure from staff, research, and moving. More than 50% of dermatology residents surveyed experienced high levels of emotional exhaustion and depersonalization, while 40% demonstrated a low sense of personal accomplishment, all of which are determinants of the burnout syndrome.3
Comparison to Residents in Other Specialties
Although dermatology residents experience lower burnout rates than colleagues in other specialties, the absolute prevalence warrants attention. A recent study published in the Journal of the American Medical Association of 3588 second-year medical residents in the United States found that rates of burnout symptoms across clinical specialties ranged from 29.6% to 63.8%. The highest rates of burnout were found in urology (63.8%), neurology (61.6%), and ophthalmology (55.8%), but the lowest reported rate of burnout was demonstrated in dermatology (29.6%).4 Although dermatology ranked the lowest, that is still nearly a whopping 1 in 3 dermatology residents with burnout symptoms. The absolute prevalence should not be obscured by the ranking among other specialties.
Preventing Burnout
Several burnout prevention and coping strategies across specialties have been suggested.
Mindfulness and Self-awareness
A study by Chaukos et al5 found that mindfulness and self-awareness are resilience factors associated with resident burnout. Counseling is one strategy demonstrated to increase self-awareness. Mindfulness may be practiced through meditation or yoga. Regular meditation has been shown to improve mood and emotional stress.6 Similarly, yoga has been shown to yield physical, emotional, and psychological benefits to resdients.7
Work Factors
A supportive clinical faculty and receiving constructive monthly performance feedback have been negatively correlated with dermatology resident burnout.3 Other workplace interventions demonstrating utility in decreasing resident burnout include increasing staff awareness about burnout, increasing support for health professionals treating challenging populations, and ensuring a reasonable workload.6
Sleep
It has been demonstrated that sleeping less than 7 hours per night also is associated with resident burnout,7 yet it has been reported that 72% of dermatology residents fall into this category.3 Poor sleep quality has been shown to be a predictor of lower academic performance. It has been proposed that to minimize sleep deprivation and poor sleep quality, institutions should focus on programs that promote regular exercise, sleep hygiene, mindfulness, and time-out activities such as meditation.7
Social Support
Focusing on peers may foster the inner strength to endure suffering.1 Venting, laughing, and discussing care with colleagues has been demonstrated to decrease anxiety.6 Work-related social networks may be strengthened through attendance at conferences, lectures, and professional organizations.7 Additionally, social supports and spending quality time with family have been demonstrated as negative predictors of dermatology resident burnout.3
Physical Exercise
Exercise has been demonstrated to improve mood, anxiety, and depression, thereby decreasing resident burnout.6
Final Thoughts
Burnout among dermatology residents warrants awareness, as it does in other medical specialties. Awareness may facilitate identification and prevention, the latter of which is perhaps best summarized by the words of psychologist Dr. Christina Maslach: “If all of the knowledge and advice about how to beat burnout could be summed up in 1 word, that word would be balance—balance between giving and getting, balance between stress and calm, balance between work and home.”8

A recent study published in the Journal of the American Medical Association of 3588 second-year medical residents in the United States found that rates of burnout symptoms across clinical specialties ranged from 29.6% to 63.8%. The highest rates of burnout were found in urology (63.8%), neurology (61.6%), and ophthalmology (55.8%), but the lowest reported rate of burnout was demonstrated in dermatology (29.6%).4 Although dermatology ranked the lowest, that is still nearly a whopping 1 in 3 dermatology residents with burnout symptoms. The absolute prevalence should not be obscured by the ranking among other specialties.
Preventing Burnout
Several burnout prevention and coping strategies across specialties have been suggested.
Mindfulness and Self-awareness
A study by Chaukos et al5 found that mindfulness and self-awareness are resilience factors associated with resident burnout. Counseling is one strategy demonstrated to increase self-awareness. Mindfulness may be practiced through meditation or yoga. Regular meditation has been shown to improve mood and emotional stress.6 Similarly, yoga has been shown to yield physical, emotional, and psychological benefits to resdients.7
Work Factors
A supportive clinical faculty and receiving constructive monthly performance feedback have been negatively correlated with dermatology resident burnout.3 Other workplace interventions demonstrating utility in decreasing resident burnout include increasing staff awareness about burnout, increasing support for health professionals treating challenging populations, and ensuring a reasonable workload.6
Sleep
It has been demonstrated that sleeping less than 7 hours per night also is associated with resident burnout,7 yet it has been reported that 72% of dermatology residents fall into this category.3 Poor sleep quality has been shown to be a predictor of lower academic performance. It has been proposed that to minimize sleep deprivation and poor sleep quality, institutions should focus on programs that promote regular exercise, sleep hygiene, mindfulness, and time-out activities such as meditation.7
Social Support
Focusing on peers may foster the inner strength to endure suffering.1 Venting, laughing, and discussing care with colleagues has been demonstrated to decrease anxiety.6 Work-related social networks may be strengthened through attendance at conferences, lectures, and professional organizations.7 Additionally, social supports and spending quality time with family have been demonstrated as negative predictors of dermatology resident burnout.3
Physical Exercise
Exercise has been demonstrated to improve mood, anxiety, and depression, thereby decreasing resident burnout.6
Final Thoughts
Burnout among dermatology residents warrants awareness, as it does in other medical specialties. Awareness may facilitate identification and prevention, the latter of which is perhaps best summarized by the words of psychologist Dr. Christina Maslach: “If all of the knowledge and advice about how to beat burnout could be summed up in 1 word, that word would be balance—balance between giving and getting, balance between stress and calm, balance between work and home.”8

How does diet affect the risk of IBD?
CHICAGO – , according to a lecture delivered at Freston Conference 2019, sponsored by the American Gastroenterological Association.
Although the literature is highly consistent, it contains discordant findings, and many questions remain unanswered. “We need more rigorous studies, and particularly more interventions, to truly understand the role diet may play in patients with IBD,” said Ashwin N. Ananthakrishnan, MD, MPH, associate professor of medicine at Massachusetts General Hospital in Boston.
Food can cause symptoms in IBD
Many patients with IBD are convinced that their diet caused their disease. A relevant point for physicians to consider is that these patients are at least as likely as is the general population to have intolerance or sensitivity to food components such as lactose and gluten. In a prospective questionnaire of 400 consecutive patients with IBD in the United Kingdom, 48% expressed the belief that diet could initiate IBD, and 57% said that diet could trigger a flare-up. In addition, 60% of respondents reported worsening of symptoms after eating certain foods, and about two-thirds deprived themselves of their favorite foods to prevent relapses (Inflamm Bowel Dis. 2016;22[1]:164-70). A French study found similar results. “Clearly there’s something there,” said Dr. Ananthakrishnan. Patients’ beliefs about the relationship between food and their symptoms are not simply misconceptions, he added.
A Canadian study published in 2016 found that almost one-third of patients with IBD avoid many food groups. “But there is significant heterogeneity in the foods that are avoided, and sometimes we mistake this heterogeneity for a lack of association between diet and symptoms in IBD,” said Dr. Ananthakrishnan. A larger number of patients avoid certain foods during periods of active disease, which suggests that food exacerbates their symptoms, he added. The same study showed that patients with IBD have more restrictive diets than do community controls. Patients eat fewer fruits and vegetables and generally consume less iron-rich food and less protein-rich food than healthy controls. GI intolerance, rather than professional advice, is the most common reason that patients with IBD restrict their diets (JPEN J Parenter Enteral Nutr. 2016;40[3]:405-11.).
A cross-sectional survey of 130 patients with IBD and 70 controls yielded similar results. Among patients, GI symptoms that resulted from consuming foods were not related to disease activity, disease location, or prior surgery. Patients with IBD tended to have greater frequency of GI intolerance to foods than did controls (Scand J Gastroenterol. 1997;32[6]:569-71.).
Diet may cause intestinal inflammation
International research has recorded increases in the consumption of sugar and fat (particularly saturated fat) and concomitant decreases in fiber consumption during the past several decades. The incidence of IBD has increased in parallel with these dietary changes with a remarkably similar trajectory, said Dr. Ananthakrishnan. The correlation between dietary changes and IBD incidence “holds true even more strikingly in countries that are now experiencing Westernization,” he added. These countries have undergone more rapid dietary changes, and their IBD incidence has doubled or tripled. The transition to “less traditional diets” appears to promote intestinal inflammation, said Dr. Ananthakrishnan.
An analysis of data from the European Prospective Investigation into Cancer (EPIC) study found an association between high consumption of sugar and soft drinks, together with low consumption of vegetables, and risk of ulcerative colitis (Inflamm Bowel Dis. 2016;22[2]:345-54.). A subsequent analysis of data from two prospective Swedish cohorts, however, found no association between consumption of sugary beverages and risk of Crohn’s disease or ulcerative colitis (Clin Gastroenterol Hepatol. 2019;17[1]:123-9.).
Although the data on sugar are mixed, data on the association between other macronutrient groups and risk of IBD are more consistent. When Dr. Ananthakrishnan and colleagues examined data from the Nurses’ Health Study, they found that the highest quintile of dietary fiber intake was associated with a 40% reduction in risk of Crohn’s disease, compared with the lowest quintile. The observed reduction of risk seemed to be greatest for fiber derived from fruits. Fiber from cereals, whole grains, or legumes, however, did not affect risk of Crohn’s disease (Gastroenterology. 2013;145[5]:970-7.).
A separate analysis of the Nurses’ Health Study suggested that high intake of n-3 polyunsaturated fatty acids (PUFAs) and low intake of n-6 PUFAs was associated with a 31% reduction in risk of ulcerative colitis and a 15% reduction in the risk of Crohn’s disease. These data were consistent with a previous analysis of EPIC data that found that high intake of n-6 PUFAs was associated with increased risk of ulcerative colitis (Gut. 2009;58[12]:1606-11.). Other analyses indicate that genetic polymorphisms likely modify the association between PUFAs and risk of ulcerative colitis, said Dr. Ananthakrishnan. “There may be an additional layer of complexity beyond just measuring your dietary intake.”
In addition to macronutrients, micronutrients can modify a patient’s risk of ulcerative colitis or Crohn’s disease. When Dr. Ananthakrishnan and colleagues examined the Nurses’ Health Study, they found an inverse association between vitamin D intake and risk of Crohn’s disease (Gastroenterology. 2012;142[3]:482-9.). In a separate study, they found that a zinc intake greater than 16 mg/day was associated with reduced risk of Crohn’s disease (Int J Epidemiol. 2015;44[6]:1995-2005.).
Patients aged older than 40 years and patients of European ancestry tend to be overrepresented in cohort studies, which reduces the generalizability of their conclusions, said Dr. Ananthakrishnan. Furthermore, cohort studies have not produced consistent findings regarding the relationship between various dietary components and risk of IBD. Nevertheless, the data suggest that dietary patterns may be associated with incident Crohn’s disease or ulcerative colitis.
An influence of diet on IBD risk is plausible
One mechanism through which diet may exercise a causal influence on the risk of IBD is by affecting the microbiome. In 2011, investigators studied 98 healthy volunteers who answered questionnaires about their diet. The researchers also used 16s rDNA sequencing to characterize the population’s stool samples. A diet high in animal protein, amino acids, and saturated fats was associated with large populations of Bacteroides. A diet low in fat and in animal protein, but high in carbohydrates and simple sugars was associated with large populations of Prevotella. When the investigators conducted a controlled-feeding study of 10 patients, microbiome composition changed within 1 day of initiating a high-fat-and-low-fiber or a low-fat-and-high-fiber diet (Science. 2011;334[6052]:105-8.). A more recent study showed that the diversity of the microbiome increased with the adoption of an animal-based diet (Nature. 2014;505[7484]:559-63.).
Diet also may exert a causal influence on IBD risk by altering the intestinal barrier. In an experimental model, 5-mg/mL concentrations of fiber from plantain and broccoli significantly reduced the translocation of Escherichia coli through a human intestinal epithelial barrier (Gut. 2010;59[10]:1331-9.). Increased fiber intake may thus result in reduced intestinal inflammation, said Dr. Ananthakrishnan.
Observational and experimental evidence thus support an effect of diet on the risk of IBD, and experimental evidence indicates that this effect is biologically plausible. Nevertheless, “there are many missing links,” and further study will clarify the role of diet in IBD incidence, said Dr. Ananthakrishnan.
