The COVID-19 pandemic has disproportionately affected socially vulnerable communities. Some individuals experience persistent symptoms and conditions of illness known as long COVID. As little research examined how social vulnerability is related to COVID, we studied this topic using Minority Health Social Vulnerability Index (MHSVI), specifically created for the in U.S. We merged county-level MHSVI data with population-based Michigan adults PCR-confirmed SARS-CoV-2 infection between March...

Abstract Purpose To (1) assess whether residential rurality/urbanicity was associated with the prevalence of 30‐ or 90‐day long COVID, and (2) evaluate differences in COVID risk factors might explain this potential disparity. Methods We used data from Michigan COVID‐19 Recovery Surveillance Study, a population‐based probability sample adults (n = 4,937). measured using dichotomized Rural‐Urban Commuting Area codes (metropolitan, nonmetropolitan). considered outcomes 30‐day (illness duration...

Although meningioma is a benign tumour, it may cause significant morbidity. Obesity and diabetes are positively associated with meningioma. To evaluate the potential effects of obesity-related prediagnostic glucose, triglycerides cholesterol on these biomarkers, we conducted cohort study.We identified 41 355 individuals in Apolipoprotein MOrtality RISk values for biomarkers within 15 years before diagnosis, death, migration or end follow-up. We then estimated hazard ratios (HRs) their...

The objective was to determine the nasal carriage prevalence of methicillin-resistant Staphylococcus aureus (MRSA) among emergency medical service (EMS) personnel and associated risk factors. A cross-sectional study conducted Ohio EMS randomly sampled from 84 urban rural agencies. Surveys assessing demographics, occupational history, health, cohabitation status, hygiene practice were collected with swabs those who enrolled. Survey weight adjusted analysis performed (1) estimate MRSA...

Abstract Background Growing evidence suggests that severe acute COVID-19 illness increases the risk of long COVID (also known as post–COVID-19 condition ). However, few studies have examined associations between symptoms and onset. Objective This study aimed to examine symptom profiles prevalence using a population-based sample. Methods We used dual mode (phone web-based) probability survey adults with polymerase chain reaction–confirmed SARS-CoV-2 June 2020 May 2022 in Michigan Disease...

Growing evidence suggests that individuals with COVID-19 face stigmatization, which is associated poor health outcomes and behaviors. However, very few population-based studies have examined risk factors for experiencing stigma. This study prevalence predictors of perceived stigma using a probability sample adults COVID-19.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) can be found in emergency medical services (EMS) ambulances. This poses an occupational risk and patient safety hazard. Screening for environmental contamination is often not performed due to limited resources logistical challenges. study’s objective was compare traditional screening of individual surfaces versus “pooled sampling” efficiently identify contamination.
 Methods: A cross-sectional study, conducted among 145 Ohio...
