Alternatively spliced forms of fibronectin, called oncofetal fibronectin, are aberrantly expressed in cancer, with little to no expression in normal tissue, making them attractive biomarkers to exploit for tumor-targeted therapeutics and diagnostics. While prior studies have explored oncofetal fibronectin expression in limited cancer types and limited sample sizes, no studies have performed a large-scale pan-cancer analysis in the context of clinical diagnostics and prognostics to posit the utility of these biomarkers across multiple cancer types. In this study, RNA-Seq data sourced from the UCSC Toil Recompute project were extracted and analyzed to determine the correlation between the expression of oncofetal fibronectin, including extradomain A and extradomain B fibronectin, and patient diagnosis and prognosis.

An often underappreciated and hard-to-treat condition in correctional institutions is attention-deficit/hyperactivity disorder (ADHD). Although there are many effective psychopharmacologic treatments for ADHD, such as various formulations of amphetamines, many physicians are hesitant to prescribe controlled stimulants in correctional settings because of concerns about abuse and safety. Although nonstimulant alternatives are available, they are generally seen as less effective than stimulants.

Recent evolving trends in the United States legal system regarding how policies and laws are applied to pregnant women include concerns over the use of restraints or shackles in pregnant inmates and forced treatment or commitment of pregnant women for substance abuse. These topics raise many questions, such as: how violent are women, particularly pregnant women; what are the informed consent and treatment implications; and who is at risk of harm? In addition, questions have been raised regarding maternal versus fetal rights, especially when the mother uses substances during a pregnancy. We review legal decisions and organizational position statements and highlight ethics-related concerns.

There is less research about homicidal women than about their male counterparts. Women are often considered the gentler sex, and their risk of perpetrating violent acts is underestimated. In attempts to understand violence by women with mental illness, female homicide offenders found not guilty by reason of insanity (NGRI) are an important subpopulation.

Since the recent shootings in Tucson, Arizona; Aurora, Colorado; and Newtown, Connecticut, there has been an ever-increasing state and national debate regarding gun control. All 3 shootings involved an alleged shooter who attended college, and in hindsight, evidence of a mental illness was potentially present in these individuals while in school. What appears to be different about the current round of debate is that both pro-gun control and anti-gun control advocates are focusing on mentally ill individuals, early detection of mental illness during school years, and the interactions of such individuals with physicians and the mental health system as a way to solve gun violence.
