Associations Between Physical Activity and Incident Hypertension Across Strata of Body Mass Index: A Prospective Investigation in a Large Cohort of French Women.

Background High body mass index (BMI) and low physical activity are associated with increased risk of hypertension. Few studies have assessed their joint impact or the relation of physical activity and hypertension among individuals within a healthy BMI range. The objective of this study was to investigate the associations between physical activity and hypertension across strata of BMI.

Novel genetic variants of and of the endosome-related pathway predict cutaneous melanoma-specific survival.

Endosomes regulate cell polarity, adhesion, signaling, immunity, and tumor progression, which may influence cancer outcomes. Here we evaluated associations between 36,068 genetic variants of 228 endosome-related pathway genes and cutaneous melanoma disease-specific survival (CMSS) using genotyping data from two previously published genome-wide association studies. The discovery dataset included 858 CM patients with 95 deaths from The University of Texas MD Anderson Cancer Center, and the replication dataset included 409 CM patients with 48 deaths from the Nurses' Health Study (NHS) and the Health Professionals Follow-up Study (HPFS).

Periprocedural Hydrogen Sulfide Therapy Improves Vascular Remodeling and Attenuates Vein Graft Disease.

Background Failure rates after revascularization surgery remain high, both in vein grafts (VG) and arterial interventions. One promising approach to improve outcomes is endogenous upregulation of the gaseous transmitter-molecule hydrogen sulfide, via short-term dietary restriction. However, strict patient compliance stands as a potential translational barrier in the vascular surgery patient population.

Sensitivity analysis for publication bias in meta-analyses.

We propose sensitivity analyses for publication bias in meta-analyses. We consider a publication process such that 'statistically significant' results are more likely to be published than negative or "non-significant" results by an unknown ratio, . Our proposed methods also accommodate some plausible forms of selection based on a study's standard error.

Treatment of opioid use disorder during COVID-19: Experiences of clinicians transitioning to telemedicine.

Objective: The COVID-19 pandemic has transformed care delivery for patients with opioid use disorder (OUD); however, little is known about the experiences of front-line clinicians in the transition to telemedicine. This study described how, in the context of the early stages of the pandemic, clinicians used telemedicine for OUD in conjunction with in-person care, barriers encountered, and implications for quality of care.

Methods: In April 2020, we conducted semistructured interviews with clinicians waivered to prescribe buprenorphine.

Healthy Lifestyle for Prevention of Premature Death Among Users and Nonusers of Common Preventive Medications: A Prospective Study in 2 US Cohorts.

Background It remains unknown whether individuals who regularly use preventive medications receive the same benefit from healthy lifestyle as those who do not use medications. We aimed to examine the associations of healthy lifestyle with mortality according to use of major preventive medications, including aspirin, antihypertensives, and lipid-lowering medications. Methods and Results Among 79 043 women in the Nurses' Health Study (1988-2014) and 39 544 men in the Health Professionals Follow-up Study (1986-2014), we defined a healthy lifestyle score based on body mass index, smoking, physical activity, diet, and alcohol intake.

Breast cancer and the black swan.

Most current research in cancer is attempting to find ways of preventing patients from dying after metastatic relapse. Driven by data and analysis, this project is an approach to solve the problem upstream, i.e.

Risk of COVID-19 among frontline healthcare workers and the general community: a prospective cohort study.

Background: Data for frontline healthcare workers (HCWs) and risk of SARS-CoV-2 infection are limited and whether personal protective equipment (PPE) mitigates this risk is unknown. We evaluated risk for COVID-19 among frontline HCWs compared to the general community and the influence of PPE.

Methods: We performed a prospective cohort study of the general community, including frontline HCWs, who reported information through the COVID Symptom Study smartphone application beginning on March 24 (United Kingdom, U.

Mental Health Burden After Injury: It's About More than Just Posttraumatic Stress Disorder.

Objective: Assess the prevalence of anxiety, depression, and posttraumatic stress disorder (PTSD) after injury and their association with long-term functional outcomes.

Background: Mental health disorders (MHD) after injury have been associated with worse long-term outcomes. However, prior studies almost exclusively focused on PTSD.

Pharmacokinetics and Safety of a Raltegravir-Containing Regimen in Children Aged 4 Weeks to 2 Years Living With Human Immunodeficiency Virus and Receiving Rifampin for Tuberculosis.

Unlabelled: Pharmacological interactions limit treatment options for children living with human immunodeficiency virus (HIV) and tuberculosis (TB). We found that 12 mg/kg twice daily raltegravir chewable tablets (administered after crushing) safely achieved pharmacokinetic targets in children living with HIV aged 4 weeks to <2 years receiving concurrent rifampin to treat TB.

Combined Effects of Physical Activity and Air Pollution on Cardiovascular Disease: A Population-Based Study.

Background Physical activity (PA), particularly outdoor PA, may have dual effects on cardiovascular disease (CVD) risk: health benefits of exercise and potential harmful effects attributable to increased exposure to air pollution. We examined the combined effects of PA and air pollution on CVD. Methods and Results Sampling from a nationwide cohort study of the Korean National Health Insurance Service, we examined 189 771 adults aged ≥40 years who underwent health examination between 2009 and 2010.

Evaluation of Mexico's low cancer mortality using two national death registries.

Objective: To compare cancer mortality rates in Mexico from two national death registries that independently code and attribute cause of death.

Materials And Methods: We compared 5-year age-standardized total cancer and sitespecific cancer mortality rates (2010-2014) from Mexico's official death registry with a death registry from a disease surveillance system. We obtained age-adjusted mortality rates and 95% confidence intervals using the direct method and World Population Prospects 2010 as a standard.
