Naturalistic substance use before/during MTurk research participation is associated with increased substance demand and craving.

Although crowdsourcing platforms are widely used in substance-use research, it is unclear what percentage of participants use substances at the time of participation and how this might affect data quality, behavioral outcomes, or decision making. We conducted a secondary analysis of data collected on MTurk for a two-session, within-subject experiment recruiting individuals who regularly use alcohol, cannabis, cigarettes, or opioids. We analyzed 527 observations collected across two sessions (Session 1: = 303, Session 2: = 224) on measures of substance use before (within 3 hr)/during participation, data quality, demand in hypothetical purchase tasks, delay discounting, and craving.

The v-safe after vaccination health checker: Active vaccine safety monitoring during CDC's COVID-19 pandemic response.

The Centers for Disease Control and Prevention (CDC) developed and implemented the v-safe after vaccination health checker (v-safe) to monitor COVID-19 vaccine safety and as an active surveillance supplement to existing CDC vaccine safety monitoring programs. V-safe allows persons who received COVID-19 vaccines to report on post-vaccination experiences and how symptoms affected their health at daily, weekly, and monthly timepoints after vaccination. Text message reminders are sent linking to Internet-based health check-in surveys.

Spectrum of Kidney Injury Following COVID-19 Disease: Renal Biopsy Findings in a Single Italian Pathology Service.

The onset of coronavirus disease (COVID-19) as a pandemic infection, has led to increasing insights on its pathophysiology and clinical features being revealed, such as a noticeable kidney involvement. In this study, we describe the histopathological, immunofluorescence, and ultrastructural features of biopsy-proven kidney injury observed in a series of SARS-CoV-2 positive cases in our institution from April 2020 to November 2021. We retrieved and retrospectively reviewed nine cases (two pediatric and seven adults) that experienced nephrotic syndrome (six cases), acute kidney injury (two cases), and a clinically silent microhematuria and leukocyturia.
