High school seniors who used e-cigarettes may have otherwise been cigarette smokers: Evidence from Monitoring the Future (United States, 2009-2018).

Nicotine Tob Res 2021 May 15. Epub 2021 May 15.

FXB Center for Health and Human Rights, Harvard University, Boston, MA.

Introduction: Studies have indicated that youth who use e-cigarettes are more likely to progress to cigarette smoking; however, the likelihood that these youth would have used tobacco products in the pre-vaping era is unclear. This study sought to determine whether youth who used e-cigarettes in 2014-2018 would have likely been smokers in the period preceding e-cigarette availability.

Methods: Analyzing Monitoring the Future 12 th grade data (USA, 2009-2018), we forecasted the prevalence of current smoking with logistic regression-derived propensity scores. Read More

Low LDL-C levels are associated with risk of mortality in a Chinese cohort study.

Endocrine 2021 May 14. Epub 2021 May 14.

Department of Epidemiology and Biostatistics, Zhejiang University School of Public Health, Zhejiang, 310058, Hangzhou, China.

Background And Aims: Although low-density lipoprotein cholesterol (LDL-C) has been considered as a risk factor of atherosclerotic cardiovascular disease, limited studies can be available to evaluate the association of LDL-C with risk of mortality in the general population. This study aimed to examine the association of LDL-C level with risk of mortality using a propensity-score weighting method in a Chinese population, based on the health examination data.

Methods: We performed a retrospective cohort study with 65,517 participants aged 40 years or older in Ningbo city, Zhejiang. Read More

Duration of Untreated Psychosis in First-Episode Psychosis is not Associated With Common Genetic Variants for Major Psychiatric Conditions: Results From the Multi-Center EU-GEI Study.

Schizophr Bull 2021 May 8. Epub 2021 May 8.

Department of Experimental Biomedicine and Clinical Neuroscience, University of Palermo, Palermo, Italy.

Duration of untreated psychosis (DUP) is associated with clinical outcomes in people with a diagnosis of first-episode psychosis (FEP), but factors associated with length of DUP are still poorly understood. Aiming to obtain insights into the possible biological impact on DUP, we report genetic analyses of a large multi-center phenotypically well-defined sample encompassing individuals with a diagnosis of FEP recruited from 6 countries spanning 17 research sites, as part of the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. Genetic propensity was measured using polygenic scores for schizophrenia (SZ-PGS), bipolar disorder (BD-PGS), major depressive disorder (MDD-PGS), and intelligence (IQ-PGS), which were calculated based on the results from the most recent genome-wide association meta-analyses.

Human convalescent plasma protects K18-hACE2 mice against severe respiratory disease.

J Gen Virol 2021 05;102(5)

Virology Division, United States Army Medical Research Institute of Infectious Diseases, Fort Detrick, MD 21702, USA.

SARS-CoV-2 is the causative agent of COVID-19 and human infections have resulted in a global health emergency. Small animal models that reproduce key elements of SARS-CoV-2 human infections are needed to rigorously screen candidate drugs to mitigate severe disease and prevent the spread of SARS-CoV-2. We and others have reported that transgenic mice expressing the human angiotensin-converting enzyme 2 (hACE2) viral receptor under the control of the Keratin 18 (K18) promoter develop severe and lethal respiratory disease subsequent to SARS-CoV-2 intranasal challenge.

Proposal for the binding mode of the 23-mer inhibitory peptide to myostatin.

Bioorg Med Chem 2021 Apr 29;40:116181. Epub 2021 Apr 29.

Department of Medicinal Chemistry, Tokyo University of Pharmacy and Life Sciences, Hachioji, Tokyo 192-0392, Japan. Electronic address:

Inhibition of myostatin is a promising strategy for the treatment of amyotrophic disorders. Previously, we identified a minimum 23-mer peptide spanning positions 21-43 of a mouse myostatin precursor-derived prodomain and identified the nine key residues for effective myostatin inhibition through Ala scanning. We also reported the 23-mer peptides that show the propensity to form an α-helical structure around positions 32-36. Read More

Generally rare but occasionally severe weight gain after switching to an integrase inhibitor in virally suppressed AGEhIV cohort participants.

PLoS One 2021 5;16(5):e0251205. Epub 2021 May 5.

Department of Internal Medicine, Amsterdam Infection and Immunity Institute and Amsterdam Public Health Research Institute, Amsterdam UMC, University of Amsterdam, Amsterdam, The Netherlands.

Size matters in atrial fibrillation: the underestimated importance of reduction of contiguous electrical mass underlying the effectiveness of catheter ablation.

Europace 2021 May 5. Epub 2021 May 5.

Division of Cardiology, University of British Columbia, 740 Hillside Ave, Vancouver, BC V8T 1Z4, Canada.

Evidence has accumulated over the last century of the importance of a critical electrical mass in sustaining atrial fibrillation (AF). AF ablation certainly reduces electrically contiguous atrial mass, but this is not widely accepted to be an important part of its mechanism of action. In this article, we review data showing that atrial size is correlated in many settings with AF propensity. Read More
