A study published last spring suggesting that hearing aids may help reduce dementia risk has been retracted due to a coding error identified by the authors. 

The study was published April 13 in The Lancet Public Health and reported at that time. It was retracted by the journal on December 12.

According to the retraction notice, the journal editors in late November were informed by the authors of the paper that an error was introduced in the output format setting of their SAS codes, which led to data for people with hearing loss using hearing aids and those with hearing loss without using hearing aids being switched. 

This led to errors in their analysis, “which render their findings and conclusions false and misleading,” the retraction notice states. 

These errors were identified by the researchers following an exchange with scientists seeking to reproduce the authors’ findings.In a statement, The Lancet Group said it “takes issues relating to research integrity extremely seriously” and follows best-practice guidance from the Committee on Publication Ethics (COPE) and the International Committee of Medical Journal Editors (ICMJE). 

“Retractions are a rare but important part of the publishing process, and we are grateful to the scientists who prompted the re-examination of the data,” the statement reads. 

Despite the retraction, other studies have suggested a link between hearing and dementia. 

One study of US Medicare beneficiaries found a 61% higher dementia prevalence in those with moderate to severe hearing loss compared to those with normal hearing.

In this research, even mild hearing loss was associated with increased dementia risk, although it was not statistically significant, and use of hearing aids was tied to a 32% decrease in dementia prevalence. 

In addition, a large meta-analysis showed that hearing aids significantly reduce the risk for cognitive decline and dementia and even improve short-term cognitive function in individuals with hearing loss.

TOPLINE:

Pregnancy weight gain is lower in women with a history of gastric bypass or sleeve gastrectomy than in those without such a history, especially when the interval between surgery and conception is shorter, new data suggest.

METHODOLOGY:

• Using Swedish national registers, researchers investigated the association of pregnancy weight gain with  history in 12,776 pregnancies — 6388 in women with a history of bariatric surgery and 6388 in women without such a history.
• Pregnancies were propensity score matched to patients’ early-pregnancy body mass index (BMI), prepregnancy diabetes, , smoking status, education, height, country of birth, and delivery year.
• Post-gastric bypass pregnancies were matched to post-sleeve gastrectomy pregnancies using the same matching strategy.
• Time from surgery to conception was also assessed.

TAKEAWAY:

• Across all early-pregnancy BMI strata, women with a history of bariatric surgery had lower pregnancy weight gain than matched controls.
• The magnitude of difference was largest for women with normal weight or overweight early-pregnancy BMI status (adjusted mean difference in z score, −0.33), which then decreased stepwise within the  subclasses (−0.21, −0.16, and −0.08 for obesity classes I, II, and III, respectively).
• Pregnancy weight gain did not differ by surgery type, but lower pregnancy weight gain was associated with a shorter surgery-to-conception interval (particularly within 1 year) or lower surgery-to-conception weight loss.

IN PRACTICE:

“The highest proportion of weight gain below the recommendations was found among women with a normal weight status. Hence, clinical attention to women with history of bariatric surgery and a normal weight status in early pregnancy might be warranted,” the authors advised.

SOURCE:

The study, with the first author Huiling Xu, MD, MSc, Karolinska Institutet, Stockholm, Sweden, was published online in JAMA Network Open.

LIMITATIONS:

Despite rigorous matching, residual confounding was possible. The sample size was limited for some subgroups, possibly affecting statistical power. Although the study provides an overview of pregnancy outcomes within surgery-to-conception interval and pregnancy weight gain z scores, a more in-depth investigation is needed to understand the associations among bariatric surgery, pregnancy weight gain, and pregnancy outcomes.

DISCLOSURES:

Research for this study was supported by the Swedish Research Council for Health, Working Life and Welfare, and the Swedish Research Council. The authors have no relevant disclosures.

TOPLINE:

Light therapy leads to significant improvement in several sleep measures and helps alleviate depression and agitation in patients with Alzheimer’s disease (AD), a meta-analysis of 15 high-quality trials shows.

METHODOLOGY:

• This meta-analysis included 15 randomized controlled trials involving 598 patients with mild to moderate AD.
• The included trials were written in English, published between 2005 and 2022, and performed in seven countries. A fixed-effects model was used for data analysis.

TAKEAWAY:

• Light therapy significantly improved sleep efficiency (mean difference [MD], −2.42; P < .00001), increased interdaily stability (MD, −0.04; P < .00001), and reduced intradaily variability (MD, −0.04; P < .00001), indicating better sleep quality.
• Light therapy reduced agitation (MD, −3.97; P < .00001), depression (MD, −2.55; P < .00001), and caregiver burden (MD, −3.57; P < .00001).
• Light therapy also had a significant advantage over usual care in reducing the severity of psychobehavioral symptoms as assessed by the Neuropsychiatric Inventory (MD, −3.07; P < .00001).
• Light therapy had no statistically significant effect on improving cognitive function as measured by the Mini-Mental State Examination.

IN PRACTICE:

“These findings, combined with its low side-effects, suggest the role of light therapy as a promising treatment for AD. Although light therapy has fewer side effects than pharmacological treatment, adverse behavioral outcomes in patients due to bright light exposure should be considered,” the authors wrote.

SOURCE:

The study by Lili Zang and colleagues from Weifang Medical University School of Nursing, Shandong Province, China, was published online on December 6, 2023, in PLOS One.

LIMITATIONS:

The types and degrees of dementia in the included studies were inconsistent, potentially affecting the outcome indicators. Some articles did not clearly describe their randomization and allocation concealment methods, indicating possible bias in these studies.

DISCLOSURES:

The study was supported by the Natural Science Foundation of Shandong Province, China. The authors declared no competing interests.

Megan Brooks has disclosed no relevant financial relationships.

Depression, constipation, cystitis/urinary tract infections (UTIs), and sexual dysfunction may be early warning signs of multiple sclerosis (MS) 5 years prior to diagnosis, new research shows.

However, these prodromal symptoms are also more likely to occur in people with two other autoimmune diseases — lupus and Crohn’s disease — and therefore, will not help earlier diagnosis, study investigator, Céline Louapre, professor of neurology, Sorbonne University and Paris Brain Institute, Paris, France, said in an interview.

“On the other hand, in certain patients who may be at particular risk of developing MS, such as in certain familial forms or in patients with incidental inflammatory lesions discovered on MRI, the presence of these symptoms could suggest an already active process, prior to the first typical symptoms of the disease,” she noted.
 

Retracing MS Origins

The case-control study, published online in Neurology, included 20,174 people with newly diagnosed MS who were matched to 54,790 without MS, as well as 30,477 with Crohn’s disease and 7337 with lupus.

Using International Classification of Diseases, 10th revision (ICD-10) codes in electronic health records, the researchers assessed the associations between 113 diseases and symptoms in the 5 years before and after an MS diagnosis.

Twelve ICD-10 codes were significantly positively associated with the risk for MS compared with controls without MS.

After considering ICD-10 codes suggestive of neurologic symptoms as the first diagnosis of MS, the following five ICD-10 codes remained significantly associated with MS:

• Depression (odds ratio [OR], 1.22; 95% CI, 1.11-1.34)
• Sexual dysfunction (OR, 1.47; 95% CI, 1.11-1.95)
• Constipation (OR, 1.5; 95% CI, 1.27-1.78)
• Cystitis (OR, 1.21; 95% CI, 1.05-1.39)
• UTIs of unspecified site (OR, 1.38; 95% CI, 1.18-1.61)

However, none of these conditions was selectively associated with MS in comparison with both lupus and Crohn’s disease. All five ICD-10 codes identified were still associated with MS during the 5 years after diagnosis.

“The importance of investigating prodromal signs in MS is that it allows us to retrace the origins of the disease,” said Dr. Louapre.

“The main contribution of the data on prodromes in MS is to clarify that the disease and its mechanisms are frequently underway well before the first typical neurological symptoms, and that the causes of MS are probably present many years before diagnosis,” she added.

A limitation of the study was that data were not available for other factors that could influence people’s risk of developing MS, such as education level, ethnicity, body mass index, socioeconomic status, or genetic information.

It also remains unclear whether the conditions linked to MS are risk factors for the disease or nonspecific early MS symptoms.
 

Preventing Disease Evolution

In a linked editorial, Ruth Ann Marrie, MD, PhD, with the University of Manitoba, Manitoba, Canada, and Raffaele Palladino, MD, PhD, with the University of Naples Federico II, Naples, Italy, note these findings highlight the challenges of accurately identifying the prodromal stage of a specific disease.

“Commonalities of prodromal features are recognized across neurodegenerative diseases; this is also true for immune-mediated diseases, and it is not surprising, given shared etiologic factors and pathobiological mechanisms,” they point out.

“This suggests that we should be trying to link prodromal features to specific underlying pathobiological changes rather than specific diseases. This approach would require use of different study designs, including broad, deeply phenotyped cohorts, but would allow us to develop and test interventions targeted at those mechanisms, and could ultimately achieve the goal of preventing disease evolution,” they add.

The study was supported by the French National Research Agency. Dr. Louapre has received consulting or travel fees from Biogen, Novartis, Roche, Sanofi, Teva, and Merck Serono, unrelated to this study. Dr. Marrie is a coinvestigator on studies receiving funding from Biogen Idec and Roche Canada; receives research funding from CIHR, Research Manitoba, Multiple Sclerosis Society of Canada, Multiple Sclerosis Scientific Foundation, Crohn’s and Colitis Canada, National Multiple Sclerosis Society, CMSC, the Arthritis Society and the US Department of Defense; and serves on the editorial board of Neurology. Dr. Palladino has taken part in advisory boards/consultancy for MSD and Sanofi and has received support from the UK MS Society.

SAN ANTONIO — Fertility preservation and/or assisted reproductive technologies do not increase the risk for short-term cancer recurrence in young women with early hormone receptor (HR)-positive breast cancer who pause endocrine therapy to conceive, according to new data from the POSITIVE trial.

“We believe these data are of vital importance for the oncofertility counseling of young breast cancer patients,” Hatem A. Azim Jr., MD, PhD, adjunct professor, School of Medicine and Breast Cancer Center, Monterrey Institute of Technology, Mexico, said in a presentation at the San Antonio Breast Cancer Symposium.

As reported previously by this news organization, the primary results of the POSITIVE trial showed that interrupting endocrine therapy to allow pregnancy does not increase the risk of recurrence at 41 months follow-up. 

Yet, there is concern that use of fertility preservation or assisted reproductive technology methods — especially those that entail the use of hormones — could have harmful effects on patients with HR-positive breast cancers, Dr. Azim explained. 

To investigate, Dr. Azim and colleagues did a secondary analysis of outcomes from the POSITIVE trial, focusing on resumption of menstruation and use of fertility preservation and assisted reproductive technologies. 

Among 516 women evaluated for the menstruation analysis, two thirds were aged 35 and older and a little more than half (53%) reported amenorrhea at enrollment, “which is not surprising,” Dr. Azim said. 

“What is encouraging,” he said, is that 85% of women recovered menses within 6 months and 94% within 12 months of pausing endocrine therapy.

Among 497 evaluable participants who paused endocrine therapy to attempt pregnancy, 368 (74%) became pregnant.

Looking at time to pregnancy, there was a clear association between younger age at enrollment and shorter time to pregnancy. The cumulative incidence of pregnancy at 12 months was 64% in women younger than age 35 years, 54% in those aged 35-39, and 38% in those age 40-42. In a multivariable model, age < 35 was the only factor independently associated with a shorter time to pregnancy. 
 

No Harmful Impact on Breast Cancer Outcomes

Turning to fertility preservation and use of assisted reproductive technologies, roughly half of the women (51%) underwent some form of fertility preservation at breast cancer diagnosis and before trial enrollment, most commonly ovarian stimulation for embryo or oocyte cryopreservation.

After enrollment, 43% of women underwent some form of assisted reproductive technology to attempt pregnancy, most commonly ovarian stimulation for in vitro fertilization (IVF) and cryopreserved embryo transfer.

In the multivariable model, cryopreserved embryo transfer was the only assisted reproductive technology significantly associated with a greater chance of becoming pregnant, more than doubling patients’ odds (odds ratio, 2.4).

“This means that at breast cancer diagnosis, we should consider cryopreservation of embryos for future use if desired,” Dr. Azim said. 

Again, age mattered. Women younger than 35 undergoing assisted reproductive technologies had a 50% higher chance of becoming pregnant compared with peers aged 35-39, and an 84% higher chance than women aged 40-42. 

Importantly, there was no apparent short-term detrimental impact of fertility preservation and/or assisted reproductive technologies on breast cancer outcomes, Dr. Azim reported. At 3 years, the breast cancer-free interval was almost identical between women who underwent ovarian stimulation for cryopreservation and those who did not (9.7% vs 8.7%).

“POSITIVE showed positive results that emphasize the importance of active oncofertility counseling with the patient starting at diagnosis,” said Hee Jeong Kim, MD, PhD, professor, Division of Breast Surgery, Asan Medical Center, Seoul, Republic of Korea, and discussant for the study. 

“These data are reassuring for our young patients with a diagnosis of breast cancer and shows that assisted reproductive technology is an option and is probably safe to do with the caveat that it needs longer follow-up,” added SABCS codirector Carlos Arteaga, MD, director, Simmons Comprehensive Cancer Center, UT Southwestern Medical Center, Dallas.

SAN ANTONIO — Fertility preservation and/or assisted reproductive technologies do not increase the risk for short-term cancer recurrence in young women with early hormone receptor (HR)-positive breast cancer who pause endocrine therapy to conceive, according to new data from the POSITIVE trial.

SAN ANTONIO — Guideline-concordant care is associated with improved overall survival in patients with inflammatory breast cancer. Yet, a retrospective study of patients with inflammatory breast carcinoma shows that the majority of patients don’t receive it. 

The study also showed that overall survival was lowest for Black women who didn’t receive guideline-concordant care, said Brian Diskin, MD, with the Division of Breast Surgery, Memorial Sloan Kettering Cancer Center, New York City, here at the San Antonio Breast Cancer Symposium.

The results highlight the importance of adhering to guidelines in inflammatory breast carcinoma and suggest that improving the rates among Black patients “may help to mitigate racial disparities and survival,” Dr.Diskin told the conference. 

Inflammatory breast carcinoma is an aggressive form of breast cancer associated with worse survival outcomes compared with other subtypes of breast cancer. Yet, it’s unclear how often and consistently guideline-concordant care — defined as treatment with neoadjuvant chemotherapy followed by modified radical mastectomy without immediate reconstruction, and postmastectomy radiotherapy — is received and what factors play a role in receiving recommended care. 

To investigate, Dr. Diskin and colleagues identified 6945 women from the National Cancer Database with nonmetastatic inflammatory breast cancer treated from 2010-2018. Guideline-concordant care was defined as trimodality treatment administered in the correct sequence, with neoadjuvant chemotherapy started within 60 days of diagnosis. 

Most patients (88%) did not start neoadjuvant chemotherapy within 60 days of diagnosis. 

Black and Asian patients were less likely than were White patients to start chemotherapy within 60 days (odds ratio [OR] 0.54 and 0.51, respectively; P < .001), while patients with Medicare or private insurance were more likely to receive chemotherapy within 60 days of diagnosis than uninsured patients (OR 1.37 and 1.87, respectively; P < .001).

Roughly half of all patients didn’t receive appropriate surgical treatment (modified radical mastectomy without immediate reconstruction and postmastectomy radiotherapy). 

Overall, only about one third of the cohort received guideline-concordant treatment, Dr. Diskin reported. 

Patients aged 60-69 were more likely than were patients aged 40-49 to receive guideline-concordant treatment (odds ratio [OR], 1.24; P < .001), as were patients with a higher clinical nodal burden (OR, 1.34 for N1; OR, 1.28 for N2; OR, 1.15 for N3 vs N0; P < .001 for N1 and N2). 

Patients treated between 2014 and 2018 were less likely to receive guideline-concordant treatment than patients treated between 2010 and 2013 (OR, 0.63; P <.001). 

Receiving guideline-concordant care and being privately insured were both positively associated with improved overall survival (OR, 0.75 and 0.62, respectively; P < .001). Conversely, triple-negative subtype and Black race were associated with worse overall survival (HR, 1.6 and 1.4, respectively; P < .001). 

However, timely receipt of guideline-concordant care for Black patients with triple-negative disease did lead to improved overall survival. Among recipients of guideline-based care with triple-negative disease, there was no racial disparity in overall survival. 

Study discussant Kathryn Hudson, MD, director of survivorship and medical oncologist at Texas Oncology, Austin, said it’s important to note that Black women have a 4% lower incidence of breast cancer than do White women but a 40% higher breast cancer death rate. 

“This study is important because it confirms that those who receive guideline-based care have better outcomes and that Black women have worse survival in [inflammatory breast cancer],” Dr. Hudson said. 

The finding that Black and Asian women in the study were less likely to have timely neoadjuvant chemotherapy, “likely reflects worse access to care, and this may play a role in why Black women had worse outcomes,” she added. 

Dr. Hudson said she found it “surprising” that only about one third of patients received guideline-concordant care.

In her view, “the take-home message is that improving guideline-concordant will improve outcomes for all patients with inflammatory breast cancer. And it’s really important, as a next step, to examine the barriers to guideline-concordant care in inflammatory breast cancer and continue to understand the reasons for worse [rates of] survival of Black women.”

SAN ANTONIO — Living in food deserts and food swamps — areas with no access to healthy food, and areas with a plethora of unhealthy food options — may raise the risk of dying from postmenopausal breast cancer, a novel ecological study has found. 

“Food deserts and food swamps are both bad, but it’s worse in food swamps,” Malcolm Bevel, PhD, MSPH, with Augusta University in Georgia, said in an interview. 

He presented his research at the San Antonio Breast Cancer Symposium. 

Breast cancer is the fourth leading cause of cancer death in the United States and is one of 13 obesity-related cancers. Healthy food consumption is a protective factor shown to decrease obesity risk and postmenopausal breast cancer mortality.

However, residing in food deserts or food swamps reduces access to healthy foods and has been severely understudied regarding postmenopausal breast cancer mortality, Dr. Bevel explained. 

To investigate, Dr. Bevel and colleagues did a cross-sectional, ecological analysis where they merged 2010 to 2020 postmenopausal breast cancer mortality data from the Centers for Disease Control and Prevention (CDC) with aggregated 2012 to 2020 data from the US Department of Agriculture Food Environment Atlas.

A food swamp score was calculated as the ratio of fast-food and convenience stores to grocery stores and farmer’s markets. 

A food desert score was calculated as the proportion of residents living more than 1 mile (urban) or 10 miles (rural) from a grocery store and household income ≤ 200% of the federal poverty threshold. 

The researchers categorized food deserts and food swamps as low, moderate, or high, with higher scores denoting counties with fewer resources for healthy food. 

Counties with high postmenopausal breast cancer mortality rates had a higher percentage of non-Hispanic Black population (5.8% vs. 2.1%), poverty rates (17.2% vs 14.2%), and adult obesity (32.5% vs 32%) and diabetes rates (11.8% vs 10.5%), compared with counties with low postmenopausal breast cancer mortality rates, Dr. Bevel reported. 

The age-adjusted odds of counties having high postmenopausal breast cancer mortality was 53% higher in counties with high food desert scores (adjusted odds ratio [aOR] 1.53; 95% CI, 1.26 - 1.88), and over twofold higher in those with high food swamp scores (aOR, 2.09; 95% CI: 1.69 - 2.58).

In fully adjusted models, the likelihood of counties having moderate postmenopausal breast cancer mortality rates was 32% higher in those with moderate food swamp scores (aOR, 1.32; 95% CI, 1.03 - 1.70).

 

Growing Epidemic Requires System Change

These findings are in line with another study by Dr. Bevel and his colleagues published earlier this year in JAMA Oncology. 

In that study, communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, as reported by this news organization. 

There is a “growing epidemic” of food deserts and food swamps in the US, which could be due to systemic issues such as gentrification/redlining and lack of investment with chain grocery stores that provide healthy food options, said Dr. Bevel. 

Local policymakers and community stakeholders could implement culturally tailored, sustainable interventions for obesity and obesity-related cancer prevention, including postmenopausal breast cancer. These could include creating more walkable neighborhoods and community vegetable gardens, he suggested. 

“This is an important study demonstrating how the environment impacts outcomes in postmenopausal women diagnosed with breast cancer,” said Lia Scott, PhD, MPH, discussant for the study.

“Most of the literature is primarily focused on food deserts to characterize the food environment. However, these authors looked at both food deserts and food swamps. And even after adjusting for various factors and age, counties with high food swamp scores at greater odds of having higher postmenopausal breast cancer mortality rates,” said Dr. Scott, who is from Georgia State University School of Public Health in Atlanta.

“There is a clear need for systems change. With ecological studies like this one, we could potentially drive policy by providing actionable data,” she added. 

The study had no specific funding. Dr. Bevel and Dr. Scott report no relevant financial relationships.

“This is an important study demonstrating how the environment impacts outcomes in postmenopausal women diagnosed with breast cancer,” said Lia Scott, PhD, MPH, discussant for the study.

“Most of the literature is primarily focused on food deserts to characterize the food environment. However, these authors looked at both food deserts and food swamps. And even after adjusting for various factors and age, counties with high food swamp scores at greater odds of having higher postmenopausal breast cancer mortality rates,” said Dr. Scott, who is from Georgia State University School of Public Health in Atlanta.

“There is a clear need for systems change. With ecological studies like this one, we could potentially drive policy by providing actionable data,” she added. 

The study had no specific funding. Dr. Bevel and Dr. Scott report no relevant financial relationships.

SAN ANTONIO — Living in food deserts and food swamps — areas with no access to healthy food, and areas with a plethora of unhealthy food options — may raise the risk of dying from postmenopausal breast cancer, a novel ecological study has found. 

“Food deserts and food swamps are both bad, but it’s worse in food swamps,” Malcolm Bevel, PhD, MSPH, with Augusta University in Georgia, said in an interview. 

He presented his research at the San Antonio Breast Cancer Symposium. 

Breast cancer is the fourth leading cause of cancer death in the United States and is one of 13 obesity-related cancers. Healthy food consumption is a protective factor shown to decrease obesity risk and postmenopausal breast cancer mortality.

However, residing in food deserts or food swamps reduces access to healthy foods and has been severely understudied regarding postmenopausal breast cancer mortality, Dr. Bevel explained. 

To investigate, Dr. Bevel and colleagues did a cross-sectional, ecological analysis where they merged 2010 to 2020 postmenopausal breast cancer mortality data from the Centers for Disease Control and Prevention (CDC) with aggregated 2012 to 2020 data from the US Department of Agriculture Food Environment Atlas.

A food swamp score was calculated as the ratio of fast-food and convenience stores to grocery stores and farmer’s markets. 

A food desert score was calculated as the proportion of residents living more than 1 mile (urban) or 10 miles (rural) from a grocery store and household income ≤ 200% of the federal poverty threshold. 

The researchers categorized food deserts and food swamps as low, moderate, or high, with higher scores denoting counties with fewer resources for healthy food. 

Counties with high postmenopausal breast cancer mortality rates had a higher percentage of non-Hispanic Black population (5.8% vs. 2.1%), poverty rates (17.2% vs 14.2%), and adult obesity (32.5% vs 32%) and diabetes rates (11.8% vs 10.5%), compared with counties with low postmenopausal breast cancer mortality rates, Dr. Bevel reported. 

The age-adjusted odds of counties having high postmenopausal breast cancer mortality was 53% higher in counties with high food desert scores (adjusted odds ratio [aOR] 1.53; 95% CI, 1.26 - 1.88), and over twofold higher in those with high food swamp scores (aOR, 2.09; 95% CI: 1.69 - 2.58).

In fully adjusted models, the likelihood of counties having moderate postmenopausal breast cancer mortality rates was 32% higher in those with moderate food swamp scores (aOR, 1.32; 95% CI, 1.03 - 1.70).

 

Growing Epidemic Requires System Change

These findings are in line with another study by Dr. Bevel and his colleagues published earlier this year in JAMA Oncology. 

In that study, communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, as reported by this news organization. 

There is a “growing epidemic” of food deserts and food swamps in the US, which could be due to systemic issues such as gentrification/redlining and lack of investment with chain grocery stores that provide healthy food options, said Dr. Bevel. 

Local policymakers and community stakeholders could implement culturally tailored, sustainable interventions for obesity and obesity-related cancer prevention, including postmenopausal breast cancer. These could include creating more walkable neighborhoods and community vegetable gardens, he suggested. 

“This is an important study demonstrating how the environment impacts outcomes in postmenopausal women diagnosed with breast cancer,” said Lia Scott, PhD, MPH, discussant for the study.

TOPLINE:

People who are extroverted and conscientious and have a positive outlook may be at lower dementia risk, whereas those who score highly for neuroticism and have a negative outlook may be at increased risk, new research suggests. 

METHODOLOGY: 

• Researchers examined the link between the “big five” personality traits (conscientiousness, extraversion, openness to experience, neuroticism, and agreeableness) and subjective well-being (positive and negative affect and life satisfaction) and clinical symptoms of dementia (cognitive test performance) and neuropathology at autopsy. 
• Data for the meta-analysis came from eight longitudinal studies with 44,531 adults (aged 49-81 years at baseline; 26%-61% women) followed for up to 21 years, during which 1703 incident cases of dementia occurred. 
• Bayesian multilevel models tested whether personality traits and subjective well-being differentially predicted neuropsychological and neuropathologic characteristics of dementia. 

TAKEAWAY:

• High neuroticism, negative affect, and low conscientiousness were risk factors for dementia, whereas conscientiousness, extraversion, and positive affect were protective.
• Across all analyses, there was directional consistency in estimates across samples, which is noteworthy given between-study differences in sociodemographic and design characteristics. 
• No consistent associations were found between psychological factors and neuropathology. 
• However, individuals higher in conscientiousness who did not receive a clinical diagnosis tended to have a lower Braak stage at autopsy, suggesting the possibility that conscientiousness is related to cognitive resilience. 

IN PRACTICE:

“These results replicate and extend evidence that personality traits may assist in early identification and dementia-care planning strategies, as well as risk stratification for dementia diagnosis. Moreover, our findings provide further support for recommendations to incorporate psychological trait measures into clinical screening or diagnosis criteria,” the authors write. SOURCE:

The study, with first author Emorie Beck, PhD, Department of Psychology, University of California, Davis, was published online on November 29, 2023, in Alzheimer’s & Dementia.

 LIMITATIONS:

Access to autopsy data was limited. The findings may not generalize across racial groups. The analysis did not examine dynamic associations between changing personality and cognition and neuropathology over time.

DISCLOSURES:

The study was supported by grants from the National Institute on Aging. The authors have declared no conflicts of interest.

Blood-based liquid biopsy tests for colorectal cancer (CRC) are in development and may soon hit the market, expanding potential options for patients who refuse traditional colonoscopy. But would they be a cost-effective screening tool?

Not according to an economic analysis by researchers at Columbia University Irving Medical Center in New York.

There is “intense research and patient and public interest” in blood-based cancer tests.

“However, liquid biopsy tests may not have sufficient performance and cost too much for them to be a viable strategy at this time,” corresponding author Chin Hur, MD, MPH, told this news organization.

The study was published online on November 16, 2023 in JAMA Network Open..
 

Better, Cheaper Liquid Biopsies Needed

The researchers developed a Markov model to compare the cost effectiveness of no screening and five CRC screening strategies: colonoscopy, liquid biopsy, liquid biopsy after nonadherence to colonoscopy, stool DNA, and fecal immunochemical test (FIT).

The model simulated a hypothetical cohort of unscreened adults at average risk for CRC with screening starting at age 45 years, in line with current US Preventive Services Task Force advice.

A strategy was considered cost-effective if it had an incremental cost-effectiveness ratio (ICER) below the US willingness-to-pay threshold of $100,000 per life-year gained.

According to their model, colonoscopy was the preferred (most cost-effective) strategy with an ICER of $28,071 per life-year gained.

Offering liquid biopsy screening to adults who refuse colonoscopy was the most effective strategy in terms of number of life-years gained, but it greatly exceeded the accepted threshold of $100,000 per life-year gained coming in at $377,538 per life-year gained. The cost of liquid biopsy would have to drop by 66% for this approach to become a cost-effective option, the researchers write.

Compared with no screening, the cost of liquid biopsy would have to fall by 94% for its ICER to drop below the willingness-to-pay threshold of $100,000 per life-year gained. When compared with stool-based tests, the cost of liquid biopsy would have to drop by 43%-80% to be cost-effective.

Liquid biopsy and the liquid biopsy after refusal of colonoscopy strategies had more life-years gained when polyp detection was introduced, but they did not achieve cost-effectiveness at liquid biopsy’s current price even with perfect performance.

“With current estimate of performance and cost,” liquid biopsy for CRC screening is not cost-effective, Dr. Hur told this news organization.

Liquid biopsy tests for CRC screening may become cost-effective in the future if they are significantly less expensive or if polyp detection is introduced along with a decrease in cost, Dr. Hur said.

Making blood-based CRC screening more effective and cost-effective “is more likely to depend on the ability to detect precancerous polyps than on the detection of CRC itself,” writes John Inadomi, MD, with University of Utah School of Medicine, Salt Lake City, in an invited commentary, also published online in JAMA Network Open. 

The sensitivity of FIT for detecting advanced polyps is roughly 20%, whereas stool multitarget tests for blood and DNA or RNA detect 40%-45% of advanced polyps, Dr. Inadomi notes.

Blood-based tests, on the other hand, have been reported to detect 12%-16% of advanced polyps, “which is close to probability of a false-positive test,” he writes. “Because of their high cost, blood-based CRC screening will not be cost-effective unless they detect a greater proportion of advanced polyps than FIT.”

The need for follow-up colonoscopy in the case of a positive noncolonoscopy CRC screening test result is “an important concept that is not emphasized enough in clinical practice,” Dr. Inadomi adds. “Unfortunately, only 40% to 80% of people with positive noncolonoscopy screening test results follow-up with the requisite colonoscopy. Clinicians need to emphasize the necessity of the follow-up colonoscopy when discussing CRC screening options and adherence.”

TOPLINE:

For relief of acute migraine, triptans, ergots, and antiemetics are two to five times more effective than ibuprofen, and acetaminophen is the least effective medication, new results from large, real-world analysis of self-reported patient data show. 

METHODOLOGY: 

• Researchers analyzed nearly 11 million migraine attack records extracted from Migraine Buddy, an e-diary smartphone app, over a 6-year period. 
• They evaluated self-reported treatment effectiveness for 25 acute migraine medications among seven classes: acetaminophen, NSAIDs, triptans, combination analgesics, ergots, antiemetics, and opioids. 
• A two-level nested multivariate logistic regression model adjusted for within-subject dependency and for concomitant medications taken within each analyzed migraine attack. 
• The final analysis included nearly 5 million medication-outcome pairs from 3.1 million migraine attacks in 278,000 medication users. 

TAKEAWAY:

• Using ibuprofen as the reference, triptans, ergots, and antiemetics were the top three medication classes with the highest effectiveness (mean odds ratios [OR] 4.80, 3.02, and 2.67, respectively). 
• The next most effective medication classes were opioids (OR, 2.49), NSAIDs other than ibuprofen (OR, 1.94), combination analgesics acetaminophen/acetylsalicylic acid/caffeine (OR, 1.69), and others (OR, 1.49).
• Acetaminophen (OR, 0.83) was considered to be the least effective.
• The most effective individual medications were eletriptan (Relpax) (OR, 6.1); zolmitriptan (Zomig) (OR, 5.7); and sumatriptan (Imitrex) (OR, 5.2).

IN PRACTICE:

“Our findings that triptans, ergots, and antiemetics are the most effective classes of medications align with the guideline recommendations and offer generalizable insights to complement clinical practice,” the authors wrote.
