Local gun violence, mental health, and sleep: A neighborhood analysis in one hundred US Cities.

Rationale: Community gun violence significantly shapes public health and collective well-being. Understanding how gun violence is associated with community health outcomes like mental health and sleep is crucial for developing interventions to mitigate disparities exacerbated by violence exposure.

Objective: This study examines the associations between community gun violence , insufficient sleep, and poor mental health across neighborhoods in the United States.

PRAME immunohistochemistry compared to traditional FISH testing in spitzoid neoplasms and other difficult to diagnose melanocytic neoplasms.

PRAME (PReferentially expressed Antigen in Melanoma) is a gene first identified in melanoma. It has been proposed as a useful marker to differentiate melanoma from benign melanocytic neoplasms. Recently genomic testing using fluorescence hybridization has been used to aid in the diagnosis of difficult melanocytic neoplasms.

Firearm availability and police shootings of citizens: a city level analysis of fatal and injurious shootings in California and Florida.

Background: A growing body of research has found a link between firearm availability and police shootings of citizens across place. The problem, however, is that the previous studies on the topic tend to suffer from several limitations: a near exclusive focus on citizen fatalities, units of analysis at the state or county levels, and a variety of proxy measures tapping into community-level firearm access. The current study set out to address these issues by examining the relationship between different forms of firearm availability and both fatal and nonfatal injurious police shootings of citizens at the city level.
