Alcohol consumption is known to have a dose-dependent association with the risk of new-onset atrial fibrillation (AFib), but the mechanism underlying this association was not clear, according to Yun Gi Kim, MD, from the Seoul National University (South Korea), and coauthors.

They analyzed data from the Korean National Health Insurance Service database for 9,776,956 individuals without atrial fibrillation at baseline, including health survey information about their alcohol consumption.

Overall, 51.3% of the study population were classified as nondrinkers, 32.1% were mild drinkers – defined as up to 105 g of alcohol consumed per week ­– 9.7% were moderate drinkers consuming 105-210 g/week, and 6.9% were heavy drinkers consuming 210 g or more per week.

The analysis revealed that heavy drinkers had the highest risk for new-onset AFib – 21.5% higher than mild drinkers – while nondrinkers had an 8.6% higher risk and moderate drinkers had a 7.7% higher risk, compared with mild drinkers.

It also showed an association between the number of drinking sessions per week and the development of new-onset atrial fibrillation. Individuals who only drank once per week had the lowest risk of AFib while those who drank every day had the highest.

“Although weekly alcohol intake was associated with the risk of new-onset [AFib], such association was lost when drinking frequency was included in the multivariate model,” the authors wrote.

They found a significant inverse relationship between the amount of alcohol consumed per drinking session, and the risk of new-onset AFib, such that individuals who consumed low amounts of alcohol per session had a higher risk, and the risk decreased as higher amounts were consumed.

“Regardless of whether weekly alcohol intake exceeded 210 g, the frequency of drinking was significantly associated with risk of new-onset [AFib],” they reported. “Patients who drink everyday represented the highest-risk group and those who drink once per week were the lowest-risk group for new-onset [AFib] in this investigation, respectively.”

The authors speculated that if alcohol consumption can trigger AFib, then multiple drinking episodes per week, regardless of amount, might trigger more episodes of AFib and potentially lead to the development of overt, new-onset disease. They also suggested that frequent drinking could lead to regular sleep disturbance, which might also contribute to the link with atrial fibrillation.

The study was supported by Korea University, Korea University Anam Hospital, Republic of Korea, the National Research Foundation of Korea, the Ministry of Education and the Ministry of Science, ICT, and Future Planning. No conflicts of interest were declared.

A new study has found that beta-blocker treatment did not prevent exacerbations in patients with moderate or severe chronic obstructive pulmonary disease (COPD).

decade3d/Thinkstock

“These results differ from previously reported findings from observational studies suggesting that beta-blockers reduce the risks of exacerbation and death from any cause in patients with COPD,” wrote Mark T. Dransfield, MD, of the University of Alabama at Birmingham and coauthors. Their findings were presented at the annual meeting of the American College of Chest Physicians and also were published simultaneously in the New England Journal of Medicine.

To determine the value of beta-blockers as a potential treatment for COPD, the researchers launched a prospective randomized trial called BLOCK COPD, consisting of 532 patients with moderate or severe COPD. They were assigned to two groups: those receiving extended-release metoprolol (n = 268) and those receiving placebo (n = 264). The mean age of all patients was 65 years.

The groups saw no significant difference in median time until the first exacerbation, which was 202 days (95% confidence interval, 162-282) in the metoprolol group and 222 days (95% CI, 189-295) in the placebo group (hazard ratio, 1.05; 95% CI, 0.84-1.32; P = .66). Metoprolol was associated with a higher risk of severe or very severe exacerbations leading to hospitalization (HR, 1.91; 95% CI, 1.29-2.83). During treatment, there were 11 deaths in the metoprolol group and 5 deaths in the placebo group.

Though there was no evidence of increases in patient-reported adverse events related to metoprolol, more discontinuations did occur in the metoprolol group compared with placebo (11.2% vs. 6.1%).

The authors acknowledged their study’s limitations, chiefly including the fact that the trial was ended early “on the basis of the conditional power analyses and concern about safety.” In addition, the reduction of heart rate and blood pressure in the metoprolol group made it impossible to fully blind the study. Finally, many patients in the trial had already suffered the effects of moderate to severe COPD, including previous hospitalization and the need for supplemental oxygen, leading to uncertainty as to “whether our results would apply to patients with mild airflow obstruction or a lower exacerbation risk.”

The study was supported by a grant from the Department of Defense. The authors reported numerous potential conflicts of interest, including receiving grants, personal fees and research funds from various pharmaceutical companies and government entities.

AUSTIN, TEX. – Patients with peripheral neuropathy may benefit from genetic testing to determine of the cause of their neuropathy even if they do not have a family history of the condition, according to new research.

The same research identified more than 80 genetic variants in patients with neuropathy who lacked any other known genetic mutations, potentially representing not-yet-identified pathogenic mutations.

Sasa Zivkovic, MD, PhD, of the University of Pittsburgh Medical Center (UPMC), and associates shared a poster of their findings at the annual meeting of the American Association for Neuromuscular and Electrodiagnostic Medicine.

The researchers conducted next-generation sequencing (NGS) on 85 adult patients with peripheral neuropathy at the UPMC Neuromuscular Clinic during May 2017–Feb. 2019. The targeted NGS panel included 70 genes. The patients, aged 60 years on average, were primarily from Allegheny County, Pa., and had neuropathy either suspected to be hereditary or of unknown etiology.

Among the 19% of patients (n = 16) who tested positive for a known pathogenic mutation, half had Charcot-Marie-Tooth disease type 1A (CMT1A). Two patients – 13% of those with pathogenic variants – had hereditary neuropathy with liability to pressure palsies, and two had CMT1X. The remaining four patients had CMT1B, CMT2B1, CMT2E, and hereditary sensory and autonomic neuropathy mutations.

Another 4% of the overall patient sample (n = 3) had likely pathogenic mutations in genes associated with CMT2S, CMT4C and CMT4F. A third of the patients (32%) tested negative for the full NGS panel, and, comprising the largest proportion of patients, 46% had variants of unknown significance.

“The high occurrence of variants of unknown significance has uncertain significance but some variations may represent unrecognized pathogenic mutations,” the authors noted.

They identified 81 of these variants, with the DST, PLEKHG5, and SPG11 genes most commonly affected, each found in six patients. Four patients had a variant in the next most commonly affected gene, SBF2. The following variants occurred in three people each: BICD2, NEFL3, PRX, SCN11A, SCN9A, SLC52A2, and WNK1.

Among the 73 patients who underwent electrodiagnostic testing, 44 had sporadic axonal neuropathy, 17 had sporadic demyelinating neuropathy, and 11 had mixed neuropathies; the 1 remaining patient was not accounted for. Positive genetic testing occurred in a third (32%) of those with familial neuropathy (n = 28) and in 12% of those with sporadic neuropathy (n = 57).

No external funding was noted, and the authors had no disclosures.

Lung function appears to continue to decline even decades after smoking cessation, according to new data from the National Heart, Lung, and Blood Institute Pooled Cohort Study. Compared with never-smokers, former smokers had a decline in forced expiratory volume in 1 second (FEV₁) about 20% as severe as current smokers, but nevertheless higher than never-smokers. Low-intensity smokers also fared worse than never-smokers, suggesting that no amount of smoke exposure should be considered safe.

The increased decline occurred even decades after smoking cessation, according to the study published in Lancet Respiratory Medicine, which was led by Elizabeth Oelsner, MD, MPH, of Columbia University, New York. Smoking prevalence has decreased from 42% to 16% in the past 50 years, and many smokers report that they smoke fewer cigarettes per day, from an average of 21 to 14, according to the authors. Despite those trends, the prevalence of chronic obstructive pulmonary disease has continued to increase, and is now the third-leading cause of death worldwide.

A meta-analysis of 47 studies and 88,887 adults found no association between smoking and FEV₁ decline, but many of the studies were small or focused on nonrepresentative populations, and they used variably standardized spirometry.

The study pooled data from nine individual U.S. cohorts, with 25,352 participants recruited during 1983-2016. Subjects included those who underwent at least two prebronchodilator spirometry tests following American Thoracic Society standards. After adjustment, former smokers had increased FEV₁ decline of 1.82 mL/year (P less than .0001), compared with never-smokers. Current smokers had an increased decline of 9.21 mL/year (P less than .0001).

Even after decades of abstinence, the effects of smoking appeared to linger: 20-30 years later, FEV₁ loss was accelerated by 2.50 mL/year (P less than .0001), and by 0.93 mL/year (P = .0104) after 30 years, compared with never-smokers.

Even low-intensity smokers (cumulative less than 10 pack-years) had an significantly accelerated FEV₁ decline (0.87 mL; P = .0153).

The researchers also found a relationship between FEV₁ decline and intensity of current smoking: Those smoking fewer than 5 cigarettes per day had a lower decline than those smoking 30 or more (7.65 mL; 95% confidence interval, 6.21-9.09 vs. 11.24 mL; 95% CI, 9.86-12.62).

The study is limited by the fact that smoking status and daily tobacco reporting were self-reported, which could result in information bias.

The study was funded by the National Institutes of Health, National Heart Lung and Blood Institute, and U.S. Environmental Protection Agency. The authors report personal fees, consultancy fees, or grants from a wide variety of pharmaceutical companies.

The study was funded by the National Institutes of Health, National Heart Lung and Blood Institute, and U.S. Environmental Protection Agency. The authors report personal fees, consultancy fees, or grants from a wide variety of pharmaceutical companies.

Type 2 diabetes patients with binge-eating psychopathology had worse glycemic control than did type 2 diabetes patients without eating disorders, but weight may be a modifying factor, according to a study of 70 outpatients with type 2 diabetes.

“Although the comorbidity of an ED [eating disorder] and T2DM [type 2 diabetes mellitus] has been observed across studies, the impact of this association on the clinical control of diabetes has been less consistent,” wrote Marcello Papelbaum, MD, of the State Institute of Diabetes and Endocrinology, Rio de Janeiro and colleagues.

In an exploratory study published in the Journal of Eating Disorders, the researchers assessed consecutive diabetes patients at a single center. The patients were aged 18-65 years, 77% were women, and 50% were obese. Glycemic control of diabetes was assessed measuring the levels of fasting blood glucose (FBG) and hemoglobin A_1c. A total of 14 patients had an eating disorder, and 7 of them had binge eating disorder (BED). The BED patients were combined with three bulimic patients and four patients with subclinical BED and classified as binge-eating related ED.

Although FBG and HbA_1c were significantly worse in patients with an eating disorder, compared with patients with normal eating patterns, the significance disappeared when body mass index (BMI) was added to the regression model. “Specifically, normal-BMI individuals exhibited a rate of ED of 8%, contrasted with a 26% prevalence of ED in obese patients,” the authors stated.

The findings were limited by the exploratory study design, small sample size, and lack of controlling for multiple variables, the researchers noted.

However, “although the objective negative clinical impact of an ED on type 2 diabetes control is yet to be confirmed, is possible to speculate that the remission of binge episodes could play a major role in diabetes treatment,” they said.

The researchers had no financial conflicts to disclose.

Drizalma Sprinkle (duloxetine delayed-release capsule) has launched for the treatment of various neuropsychiatric and pain disorders in patients with difficulty swallowing, according to a release from Sun Pharma. It can be swallowed whole, sprinkled on applesauce, or administered via nasogastric tube.

Difficulty swallowing affects approximately 30%-35% of long-term care residents, but the main alternative – crushing tablets – introduces risks of its own to the administration process.

This sprinkle is indicated for the treatment of major depressive disorder in adults, generalized anxiety disorder in patients aged 7 years and older, diabetic peripheral neuropathic pain in adults, and chronic musculoskeletal pain in adults. It was approved by the Food and Drug Administration for these indications July 19, 2019.

It carries a boxed warning for suicidal thoughts and behaviors. The most common adverse reactions (5% or more of treated participants and twice the incidence with placebo) were nausea, dry mouth, somnolence, constipation, decreased appetite, and hyperhidrosis. The full prescribing information can be found on the FDA website.

Symptoms of binge eating disorder can be assessed with a modified version of the Yale-Brown Obsessive Compulsive Scale, based on data from an analysis of three phase III studies.

The Yale-Brown Obsessive Compulsive Scale Modified for Binge Eating (Y-BOCS-BE) is designed to assess symptoms of binge eating disorder (BED), including binge eating thoughts and compulsiveness. “Psychometric testing and analysis of the Y-BOCS-BE is being conducted as a multistage process to optimize the characterization of BED,” wrote Karen Yee, PhD, of Shire (now part of Takeda), Boston, and colleagues.

In a study published in Quality of Life Research, investigators examined the validity of the Y-BOCS-BE in terms of dimensionality, internal consistency, convergent validity, test-retest reliability, and determination of clinically meaningful improvement. The Y-BOCS-BE is a 10-item clinician-rated scale with total scores from 0 to 4 on which 0 equals no symptoms and 4 equals extreme symptoms.

Overall, the Y-BOCS-BE’s internal consistency and convergent validity were maximized at 12 weeks, and test-retest reliability was maximized in an 8-week retest interval, minimal clinically important improvement could not be assessed in the two short-term efficacy studies, but “estimates in score reductions of 12-17 points were taken to represent the best estimates of clinically meaningful improvement,” the researchers said.

The findings were limited by several factors including the use of a study population of BED patients without psychiatric comorbidities, and the inclusion only of those who did not relapse the researchers noted. However, the results “set the stage for normalizing the Y-BOCS-BE and increasing the understanding of the clinical significance of Y-BOCS-BE scores and score changes to be useful both for clinical practice and clinical research,” they said.

Dr. Yee disclosed being employed by Shire and owning stock in Takeda. The studies were funded by Shire.

Approximately half of college-aged women exhibit binge eating symptoms, and these women scored significantly higher on measures of depression, stress, and anxiety than do non–binge eaters, based on data from 154 women at a Palestine Polytechnic University in Hebron.

Previous studies show that binge eating disorder is multifactorial and associated with depression and anxiety, however, “To our knowledge, no study has yet assessed the prevalence of binge eating symptoms among female university students,” wrote Manal M. Badrasawi, PhD, of An-Najah National University, Tulkarm, Palestine, and colleagues.

In a cross-sectional study published in the Journal of Eating Disorders, the researchers interviewed 154 female college students in Palestine using the using BEDS-7 (Binge Eating Disorder Screener-7). The average age of the participants was 20 years.

Overall, 50% of the students showed positive binge eating symptoms, and these individuals had significantly higher scores on measures of depression, stress, and anxiety compared to individuals without binge eating symptoms.

Binge eating also was significantly associated with greater frequency of eating between meals and increased snacking, but no significant association was noted between binge eating and sociodemographic variables, including place of residence, marital status, and years of study. Binge eating was not significantly associated with weight status.

The researchers had no financial conflicts to disclose.

WASHINGTON – A single dose of a novel monoclonal antibody against a respiratory syncytial virus surface protein safely protected preterm infants against severe infections for 150 days during their first winter season in a randomized trial with more than 1,400 children.

copyright DesignPics/Thinkstock

One intramuscular injection of nirsevimab (also known as MEDI8897) administered to infants born at 29-35 weeks’ gestation at the start of the local respiratory syncytial virus (RSV) season (November in the Northern hemisphere) led to a 70% relative reduction in the rate of medically attended lower respiratory tract infections with RSV during the subsequent 150 days, compared with placebo, the study’s primary efficacy outcome, M. Pamela Griffin, MD, said at an annual scientific meeting on infectious diseases.

In a secondary efficacy measure, the rate of hospitalizations for RSV-caused lower respiratory tract infections, a single injection of nirsevimab dropped the incidence by 78%, relative to placebo. Both effects were statistically significant. The rate of total adverse events and serious adverse events was similar in the two treatment arms, reported Dr. Griffin, a clinical development lead with AstraZeneca.

These positive results for a single intramuscular injection of nirsevimab are the first findings from a series of studies aimed at getting the monoclonal antibody onto the U.S. market as a superior alternative to palivizumab (Synagis), which acts in a similar way to block RSV infection (albeit by targeting a different viral surface protein) but which requires administration every 30 days. This need for serial dosing of palivizumab in children younger than 1 year old for complete seasonal protection against RSV is probably a reason why the American Academy of Pediatrics, as well as other medical societies, have targeted using palivizumab only on certain types of high-risk infants: those born before 29 weeks’ gestational age, with chronic lung disease of prematurity, or with hemodynamically significant congenital heart disease (Pediatrics. 2014 Aug;134[2]:415-20). “It’s not feasible for most infants to come for five treatments during RSV season,” Dr. Griffin noted. A tweak in the structure of nirsevimab gives it a much longer blood half-life than palivizumab and allows a single dose to maintain efficacy for 5 months, the duration of RSV season.

“The big advantage of nirsevimab is one dose instead of five,” she said in an interview.

The study randomized 969 preterm infants to nirsevimab and 484 to placebo when the children averaged 3 months old and 4.5 kg. The incidence of the primary endpoint was 2.6% in the nirsevimab-treated infants and 9.5% in those who received placebo. The incidence of hospitalizations associated with an RSV lower respiratory tract infection was 0.8% in the nirsevimab group and 4.1% on placebo. Nirsevimab was equally effective regardless of RSV subtype, infant age, or sex. The rate of hypersensitivity reactions was low, less than 1%, and similar in the two treatment arms, as was the rate of detection of antidrug antibody, 3.8% with placebo and 5.6% with nirsevimab.

Two other large trials are underway to document the performance of nirsevimab in other types of infants. One study is examining the drug’s performance compared with placebo in term infants with a gestational age of at least 36 weeks, while another is comparing nirsevimab against a five-dose regimen of palivizumab in high-risk infants who are recommended to receive palivizumab by local medical societies. In the United States, this would be infants born at less than 29 weeks’ gestation, and those with either hemodynamically significant congenital heart disease or chronic lung disease of prematurity. In these studies, the researchers also will assess the cost effectiveness of nirsevimab relative to the costs for medical care needed by infants who receive comparator treatments, Dr. Griffin said.

The study was funded by AstraZeneca, the company developing nirsevimab. Dr. Griffin is an employee of and shareholder in AstraZeneca.

Despite improvement, more work needs to be done in the National Institutes of Health’s work in overseeing financial conflicts of interest in extramural research, the Department of Health & Human Services’ Office of Inspector General reported.

In highlighting the improvement in a September 2019 report, “NIH has made strides in reviewing financial conflicts of interest in extramural research, but could do more,” the OIG noted that, in the past 10 years, “NIH has strengthened its reporting requirements and developed an online system for collecting, reviewing, and storing financial conflicts of interest (FCOIs) that institutions report. These changes resulted in improvements in how NIH tracks and reviews FCOIs that institutions report.”

That being said, OIG also highlighted some ongoing issues with NIH’s FCOI oversight.

“Across the three NIH Institutes and Centers (ICs) that we reviewed, staff differed in the level of scrutiny they applied to their review of FCOIs,” the report states.

For example, the report notes that 15 of the 25 ICs have written procedures related to FCOI reviews and the documentation shared by the three ICs showed different levels of detail and instruction.

“Only one of the three guidance documents provided IC staff with specific criteria aimed at standardizing the review of FCOIs,” the report stated. Two of the three ICs also reported using external resources to aid in the review.

Review times also varied significantly, with two of the three ICs reporting that they spend generally 5-30 minutes per review, while the third said staff spends several hours on reviews.

The OIG also reported that “NIH lacks quality assurance procedures in its review process. Specifically, NIH central management and the three ICs that we reviewed do not perform any systematic analyses or even ad hoc checks to determine whether staff accurately and consistently review reported FCOIs, and OIG found a small number of inconsistencies in the FCOI data that institutions reported, which might highlight the need for more oversight of the review process.”

The report notes that there is a process in place to provide oversight of ICs’ review of reported FCOIs, but there is no longer sufficient staff to continue this oversight.

The “OER [Office of Extramural Research] now relies on IC staff to seek guidance when needed and does not conduct regular oversight of the ICs. Similarly, none of the three ICs we reviewed perform quality checks to ensure the thoroughness or consistency of review by program officials. Staff members from one IC stated that while they do not conduct quality checks, the IC provides new program officials more guidance during their first few reviews.”

The HHS watchdog also noted that NIH cannot identify whether FCOIs involve foreign entities even though investigators must disclose financial interests from foreign investments.

“The HHS regulations on FCOI do not require institutions to designate whether FCOIs involve foreign entities, and NIH reported that it has no plans to expand these regulations to include such a requirement,” the OIG reported.

The OIG recommended that NIH perform periodic quality assurance reviews of FCOI information to ensure adequacy of oversight and suggested it use “information regarding foreign affiliations and support that it collects during the pre-award process to decide whether to revise its FCOI review process to address concerns regarding foreign influence.”

Despite improvement, more work needs to be done in the National Institutes of Health’s work in overseeing financial conflicts of interest in extramural research, the Department of Health & Human Services’ Office of Inspector General reported.

In highlighting the improvement in a September 2019 report, “NIH has made strides in reviewing financial conflicts of interest in extramural research, but could do more,” the OIG noted that, in the past 10 years, “NIH has strengthened its reporting requirements and developed an online system for collecting, reviewing, and storing financial conflicts of interest (FCOIs) that institutions report. These changes resulted in improvements in how NIH tracks and reviews FCOIs that institutions report.”

That being said, OIG also highlighted some ongoing issues with NIH’s FCOI oversight.

“Across the three NIH Institutes and Centers (ICs) that we reviewed, staff differed in the level of scrutiny they applied to their review of FCOIs,” the report states.

For example, the report notes that 15 of the 25 ICs have written procedures related to FCOI reviews and the documentation shared by the three ICs showed different levels of detail and instruction.

“Only one of the three guidance documents provided IC staff with specific criteria aimed at standardizing the review of FCOIs,” the report stated. Two of the three ICs also reported using external resources to aid in the review.

Review times also varied significantly, with two of the three ICs reporting that they spend generally 5-30 minutes per review, while the third said staff spends several hours on reviews.

The OIG also reported that “NIH lacks quality assurance procedures in its review process.
