The passage discusses how health inequities in the US have worsened the impact of COVID-19 on marginalized and under-resourced communities. These communities, including those in jails and prisons, immigrants and the undocumented, people with disabilities, and the homeless, face structural risks such as limited access to preventive services and inability to comply with physical distancing recommendations. Underlying health disparities and intersecting stigmas, particularly affecting racial and

This study aimed to understand the chest imaging findings of suspected COVID-19 patients in the emergency department and their relationship with demographics and RT-PCR testing results. The analysis included 227 patients, with 173 (90.1%) of the COVID-19 RT-PCR (+) cases showing abnormal imaging (85.7% on CXR and 100% on CT). The most common imaging findings were mixed

A cross-sectional social media survey was conducted from March 14-April 1, 2020, to examine the impact of shelter-in-place orders on social distancing, difficulties with daily activities, and concern regarding COVID-19 in the San Francisco Bay Area and the US. The results showed an increase in social distancing behavior (9.2% in the Bay Area and 3.4% elsewhere) and difficulties obtaining food, hand sanit

In the United States from 1999 to 2005, motor vehicle-related deaths remained relatively stable at around 15.2-15.7 per 100,000 population. However, significant variations were observed among states, regions, sexes, races, and age groups. For instance, the rate in Massachusetts was 7.9 per 100,000, while it was 31.9 in Mississippi

A study compiled data on potential explanatory variables for COVID-19 deaths in the USA through early May 2020, using statistical and machine learning approaches to identify the most significant and important variables. The findings suggest that population-weighted density, some "stay at home" metrics, monthly temperature and precipitation, race/ethnicity, and chronic low respiratory death rate were all statistically significant, with population-weighted density and mobility metrics having the greatest impact

This study provides estimates on the number of COVID-19 cases and deaths in Africa by the end of June 2020 using a co-variate-based instrumental variable regression model and adjusting for differences in age-structure, health service quality, and living standards. By the end of June, it is forecasted that 16.3 million people will contract COVID-19 with Northern Africa having the highest cumulative cases (5.4 million) and Eastern Africa

In a cohort study of COVID-19 patients in south metropolitan Chicago, predominantly African-American (AA) patients had higher rates of hospitalization and comorbidities, including diabetes mellitus, insulin use, hypertension, chronic kidney disease, coronary artery disease, and atrial fibrillation. Older age, tobacco use, CAD, and AF were associated with greater risk of in-hospital mortality. Cardiac

A retrospective study analyzed 300 patients with advanced chronic venous insufficiency who underwent radiofrequency ablation between 2009 and 2011. The study aimed to determine racial disparities in presentation and response to intervention. The patient base was predominantly female (85%) with a mean age of 53 years and a mean body mass index of 30.2. Racial distribution included Asians (3.3%

The essay discusses the disproportionate impact of Covid-19 and police violence on African American communities, highlighting the historical issues of racial health disparities and lack of autonomy in healthcare decision-making. The essay argues that systemic injustice should be considered more in clinical ethics, specifically in palliative and end-of-life care for African Americans. The essay criticizes the denial of decision-making power to African American patients and the priorit

The essay discusses the disproportionate impact of Covid-19 and systemic racism on African American communities, focusing on the implications for palliative and end-of-life care. The author argues that racial health disparities, rooted in systemic injustice, deserve greater attention in clinical ethics. African American patients have historically been denied autonomy in medical decision-making, and during the pandemic, they have been disproportionately denied access to
