MedicalResearch.com: What is the background for this study?
Response: Individuals affected by psychiatric disorders can demonstrate morphological brain abnormalities when compared to healthy controls. Although both genetic and environmental factors can account for these brain abnormalities, we expect that genetic susceptibility for psychiatric disorders has the greatest influence on the development of the brain.
Genetic susceptibility for psychiatric disorders can be estimated at the individual level by generating polygenic risk scores. Using this methodology, genetic susceptibility to psychiatric disorders and cognition has been associated with behavior problems in childhood. These findings suggest that heritable neurobiological mechanisms are at play in very early in the course of the illnesses.

MedicalResearch.com: What is the background for this study?
Response: Understanding the role of care transitions after hospitalization in reducing avoidable readmissions, the Camden Coalition launched the 7-Day Pledge in 2014 in partnership with primary care practices in Camden, NJ to address patient and provider barriers to timely post-discharge primary care follow-up. To evaluate whether our program was associated with lower hospital readmissions, we used all-payer hospital claims data from five regional health systems. We compared readmissions for patients who had a primary care follow-up within seven days with similar patients who had a later or no follow-up using propensity score matching.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: For many individuals with nonfatal firearm injuries, their only point of contact with the healthcare system may be the emergency department. Both hospital-based violence intervention programs and counseling and safe firearm storage have shown promise in reducing the burden of firearm injury.
In this study, one third of individuals with firearm injuries presented to non-trauma centers. Only 1 out of 5 firearm injuries were assault injuries that led to admission to trauma centers, the population most likely to receive interventions to reduce re-injury.

MedicalResearch.com: What is the background for this study?
Response: There is accumulating evidence that spaceflight impacts the human brain: the brain is shifted higher within the skull and there are some regions of gray matter increases and decreases.
To date, no studies have looked at the impact of spaceflight on human brain white matter pathways. Rodents flown in space show decreased myelination of white matter pathways. Here, we analyzed brain MRI scans pre and post spaceflight to quantify fluid shifts and white matter changes.
