Is pre-hospital haemoglobin an efficient marker of the need for transfusion and haemorrhagic shock in severe trauma patients? A retrospective observational study.

Background: Haemorrhagic shock is the leading cause of preventable death among trauma patients. Early detection of severe haemorrhage is essential for initiating timely resuscitation and mobilizing resources for massive transfusion (MT) protocols and damage control procedures. This study aimed to assess the predictive value of prehospital haemoglobin (Hb) levels for the need for transfusion at admission, the presence of haemorrhagic shock (HS), and the necessity for MT or haemostatic surgery.

Egg Size Scales Negatively With System Size in a Periodic Fish Species.

Optimal egg size theory implies that female organisms balance between fecundity and individual offspring investment according to their environment. Past interspecific studies suggest that fishes in large marine systems generally produce smaller eggs than those in small freshwater systems. We tested whether intraspecific egg size variation reflected a similar pattern by comparing egg size among yellow perch () populations inhabiting a range of system sizes.

Hospital design for inpatient psychiatry: A realistic umbrella review.

The evaluation of the effects of architecture and design in psychiatric hospitals primarily focuses on final outcomes, such as disease progression, and is made from the perspective of evidence-based medicine. Meanwhile, the evidence-informed, realist approach addresses how the intervention works. Understanding the underlying action mechanisms of the intervention is needed to facilitate its scaling-up and adaptation in new environments.

"It would Never have Happened Without the Pandemic": Understanding the Lived Experience of Individuals who Increased Their Online Gambling Participation.

The gambling landscape was profoundly impacted by the COVID-19 pandemic, leading to an increase in online gambling participation. This growth raises concerns about the potential harms associated with online gambling. This qualitative study aims to understand the lived experiences of gamblers whose participation in online gambling increased due to the pandemic.

Exploring the Relationship Between Anticipated Stigma and Community Shared Concerns about HIV on Defaulting from HIV Care in Rural South Africa.

Unlabelled: Although stigma has been associated with people living with HIV defaulting from care, there is a gap in understanding the specific impact of individual stigma and community-level concern about HIV on defaulting.

Methods: This is a secondary analysis of a unique dataset that links health facility-based medical records to a population-representative community survey conducted in 2018 in rural Mpumalanga province, South Africa. We used the parametric g-formula to estimate associations among individual anticipated stigma, low perceived community and local leader concern about HIV, and defaulting from care in the prior year.
