Lack of Association Between Recent Cannabis Use and Advanced Liver Fibrosis Among HIV-positive Heavy Drinkers.

Aim: This study aimed to analyze the association between any past-month cannabis use and advanced liver fibrosis.

Background: Cannabinoid receptors play a role in acute and chronic liver injury, but human studies addressing the impact of cannabis use on liver fibrosis have shown mixed results.

Objective: The objective of this study was to explore and estimate the association between pastmonth cannabis use and advanced liver fibrosis (ALF) in a cohort of Russian HIV-positive individuals with heavy alcohol use and a high prevalence of hepatitis C virus (HCV) coinfection.

Deep-Learning-Driven Quantification of Interstitial Fibrosis in Digitized Kidney Biopsies.

Interstitial fibrosis and tubular atrophy (IFTA) on a renal biopsy are strong indicators of disease chronicity and prognosis. Techniques that are typically used for IFTA grading remain manual, leading to variability among pathologists. Accurate IFTA estimation using computational techniques can reduce this variability and provide quantitative assessment.

Impact of a Multilevel Quality Improvement Intervention Using National Partnerships on Human Papillomavirus Vaccination Rates.

Objective: To evaluate the effectiveness of a multilevel intervention using national partnerships on human papillomavirus (HPV) vaccination rates.

Methods: The American Cancer Society's Vaccinate Adolescents against Cancer program is a multilevel intervention focusing on systems and providers. The 2017 cohort introduced national partnerships to deliver intervention elements and Maintenance of Certification and continuing medical education credits for physicians.

Competing risks of women and men who use fentanyl: "The number one thing I worry about would be my safety and number two would be overdose".

Background: Standard public health approaches to risk communication do not address the gendered dynamics of drug use. The aim of this study was to explore perceptions of fentanyl-related risks among women and men to inform future risk communication approaches.

Methods: We conducted a qualitative study, purposively sampling English-speaking women and men, aged 18-25 or 35+ years, with past 12-month illicitly manufactured fentanyl use.

Sex Differences in the Associations of Visceral Adipose Tissue and Cardiometabolic and Cardiovascular Disease Risk: The Framingham Heart Study.

Background Men and women are labeled as obese on the basis of a body mass index (BMI) using the same criterion despite known differences in their fat distributions. Subcutaneous adipose tissue and visceral adipose tissue (VAT), as measured by computed tomography, are advanced measures of obesity that closely correlate with cardiometabolic risk independent of BMI. However, it remains unknown whether prognostic significance of anthropometric measures of adiposity versus VAT varies in men versus women.

Opioid use disorder treatment for people experiencing homelessness: A scoping review.

Background: The opioid-related overdose epidemic remains a persistent public health problem in the United States and has been accelerated by the 2019 coronavirus disease pandemic. Existing, evidence-based treatment options for opioid use disorder (OUD) are broadly underutilized, particularly by people experiencing homelessness (PEH). PEH are also more likely to misuse and overdose on opioids.

False negative point-of-care urine pregnancy tests in an urban academic emergency department: a retrospective cohort study.

Study Objective: To determine the prevalence of false negative point-of-care (POC) urine pregnancy tests among emergency department (ED) patients and among those with abdominal pain or vaginal bleeding.

Methods: We identified all female patients, ages 14-50 years without prior hysterectomy who had a negative POC urine pregnancy test (beta subunit of human chorionic gonadotropin [β-hCG]) performed by trained clinical staff in the ED between September 1, 2017 and December 31, 2018, as well as a subgroup we defined a priori as "high risk" for early pregnancy complications based on a triage chief complaint (text) of abdominal pain or vaginal bleeding. We identified those with a positive urine β-hCG, serum β-hCG >5 mIU/mL, or a diagnosis of pregnancy within 3 months of the initial ED visit (index visit).

Seroprevalence of SARS-CoV-2 IgG antibodies and risk factors in health care workers at an academic medical center in Boston, Massachusetts.

Healthcare workers (HCWs) are at an increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel virus that causes Coronavirus Disease (COVID-19). We aim to assess the seroprevalence of SARS-CoV-2 IgG among healthcare workers and compare risk-factors between seropositive and seronegative HCWs. In this observational study, serum samples were collected from HCWs between July 13th to 26th, 2020 at Boston Medical Center (BMC).

Cytokine Levels in Human Vitreous in Proliferative Diabetic Retinopathy.

In this study, we compare the vitreous cytokine profile in patients with proliferative diabetic retinopathy (PDR) to that of patients without PDR. The identification of novel cytokines involved in the pathogenesis of PDR provides candidate therapeutic targets that may stand alone or work synergistically with current therapies in the management of diabetic retinopathy. Undiluted vitreous humor specimens were collected from 74 patients undergoing vitrectomy for various vitreoretinal disorders.

Best Practices in Global Mental Health: An Exploratory Study of Recommendations for Psychologists.

Recommendations for best practice are useful in guiding the ethical and effective practice of psychology. Global mental health (GMH), which works to improve mental health treatment and access on a worldwide scale, is a growing field with many opportunities for psychologists, though such best practice recommendations have not been articulated. Using a grounded theory approach, this qualitative study recruited and interviewed psychologists identified as leaders in the field.

Epidemiology of Heart Failure Stages in Middle-Aged Black People in the Community: Prevalence and Prognosis in the Atherosclerosis Risk in Communities Study.

Background Black individuals have a higher burden of risk factors for heart failure (HF) and subclinical left ventricular remodeling. Methods and Results We evaluated 1871 Black participants in the Atherosclerosis Risk in Communities Study cohort who attended a routine examination (1993-1996, median age 58 years) when they underwent echocardiography. We estimated the prevalences of 4 HF stages: (1) : no risk factors; (2) : presence of HF risk factors (hypertension, diabetes mellitus, obesity, smoking, dyslipidemia, coronary artery disease without clinical myocardial infarction), no cardiac structural/functional abnormality; (3) : presence of prior myocardial infarction, systolic dysfunction, left ventricular hypertrophy, regional wall motion abnormality, or left ventricular enlargement; and (4) : prevalent HF.

Blood biomarkers for dementia in Hispanic and non-Hispanic White adults.

Introduction: The study evaluated if blood markers reflecting diverse biological pathways differentiate clinical diagnostic groups among Hispanic and non-Hispanic White adults.

Methods: Within Hispanic (n = 1193) and non-Hispanic White (n = 650) participants, serum total tau (t-tau), neurofilament light (NfL), ubiquitin carboxyl-terminal hydrolase LI, glial fibrillary acidic protein (GFAP), soluble cluster of differentiation-14, and chitinase-3-like protein 1 (YKL-40) were quantified. Mixed-effects partial proportional odds ordinal logistic regression and linear mixed-effects models were used to evaluate the association of biomarkers with diagnostic group and cognition, adjusting for age, sex, ethnicity, apolipoprotein E ε4, education, and site.

Global Health Training in U.S. Emergency Medicine Residency Programs.

Objectives: Formal education in global health (GH) and short-term experiences in GH (STEGH) are offered by many emergency medicine (EM) residency programs in the United States. In an increasingly connected world, training in GH and STEGH can provide essential knowledge and practical skills to trainees, particularly at the graduate medical education level. The current core programmatic components and the essential competencies and curricula that support ethical and effective STEGH, however, still vary widely.

Conjoint Associations of Adherence to Physical Activity and Dietary Guidelines With Cardiometabolic Health: The Framingham Heart Study.

Background The conjoint associations of adherence to the recent physical activity and dietary guidelines with the metabolic syndrome (MetS) are incompletely understood. Methods and Results We evaluated 2379 FHS (Framingham Heart Study) Third Generation participants (mean age, 47 years; 54.4% women) attending examination cycle 2.

Association of Blood Pressure and Heart Rate Responses to Submaximal Exercise With Incident Heart Failure: The Framingham Heart Study.

Background Exercise stress tests are conventionally performed to assess risk of coronary artery disease. Using the FHS (Framingham Heart Study) Offspring cohort, we related blood pressure (BP) and heart rate responses during and after submaximal exercise to the incidence of heart failure (HF). Methods and Results We evaluated Framingham Offspring Study participants (n=2066; mean age, 58 years; 53% women) who completed 2 stages of an exercise test (Bruce protocol) at their seventh examination (1998-2002).

Cigarette Smoking, Incident Coronary Heart Disease, and Coronary Artery Calcification in Black Adults: The Jackson Heart Study.

Background Although Black adults are more likely to die from coronary heart disease (CHD) compared with White adults, few studies have examined the relationship between cigarette smoking and CHD risk among Black adults. We evaluated the relationship between cigarette smoking, incident CHD, and coronary artery calcification in the JHS (Jackson Heart Study). Methods and Results We classified JHS participants without a history of CHD (n=4432) by self-reported baseline smoking status into current, former (smoked at least 400 cigarettes/life) or never smokers at baseline (2000-2004).

The Hepatitis C Continuum of Care Among HIV-Positive Persons with Heavy Alcohol Use in St. Petersburg, Russia.

This study describes the self-reported prevalence of hepatitis C virus (HCV) coinfection and the HCV care continuum among persons enrolled in the St PETER HIV Study, a randomized controlled trial of medications for smoking and alcohol cessation in HIV-positive heavy drinkers and smokers in St. Petersburg, Russia. Baseline health questionnaire data were used to calculate proportions and 95% confidence intervals for self-reported steps along the HCV continuum of care.
