Gain-of-function, focal segmental glomerulosclerosis Trpc6 mutation minimally affects susceptibility to renal injury in several mouse models.

Mutations in TRPC6 are a cause of autosomal dominant focal segmental glomerulosclerosis in humans. Many of these mutations are known to have a gain-of-function effect on the non-specific cation channel function of TRPC6. In vitro studies have suggested these mutations affect several signaling pathways, but in vivo studies have largely compared wild-type and Trpc6-deficient rodents.

Trpc6 gain-of-function disease mutation enhances phosphatidylserine exposure in murine platelets.

Platelets enhance coagulation by exposing phosphatidylserine (PS) on their cell surface in response to strong agonist activation. Transient receptor potential channels, including TRPC6, have been implicated in the calcium influx central to this process. Here, we characterize the effect of a Trpc6 gain-of-function (GOF) disease-associated, and a dominant negative (DN), mutation on murine platelet activation.

Interpersonal Trauma and Posttraumatic Stress Disorder among Black Women: Does Racial Discrimination Matter?

There is evidence that the more frequent, severe, and chronic posttraumatic stress disorder (PTSD) symptomatology experienced by Black compared to White individuals cannot be explained by disparities in socioeconomic status or trauma exposure. One factor that may be important to consider is racial discrimination, which is associated with numerous negative mental health outcomes yet has not been studied in the context of interpersonal traumas for Black women. This study aims to fill this gap by examining the independent and interactive roles of racial discrimination and interpersonal trauma in predicting PTSD symptoms in a community sample of trauma-exposed, Black women ( = 292).

Emergency medicine physicians' ability to predict hospital admission at the time of triage.

Background: We seek to determine if experienced emergency medicine physicians can accurately predict the likelihood of admission for patients at the time of triage. Such predictions, if proven to be accurate, could decrease the time spent in the ED for patients who will ultimately be admitted by hastening downstream workflow.

Methods: This is a prospective cohort study of experienced physicians at a large urban hospital.

Sleep disturbances and post-traumatic stress disorder in women.

Sleep disturbances are found in a majority of individuals diagnosed with posttraumatic stress disorder (PTSD). The purpose of this literature review is to provide information about PTSD, in addition to assessing sleep quality. Current research observes that the lifetime prevalence of PTSD diagnosis in women is increasing.
