Traumatic Encephalopathy Syndrome: Head Impact Exposure and Blood Biomarkers in Professional Combat Athletes.

Objective: This study aimed to (1) determine whether there was an association between a diagnosis of traumatic encephalopathy syndrome (TES) and changes in three specific serum biomarkers, and (2) determine head impact exposure thresholds among both TES+ and TES- groups.

Setting: Data were collected from Cleveland Clinic's Professional Athletes Brain Health Study (PABHS).

Participants: This study included 192 professional combat athletes, 35 years of age and older.

A Rare Case of Gastric Outlet Obstruction Caused by a Duodenal Carcinoid.

In this case report, we discuss a very rare presentation of a duodenal carcinoid tumor causing a gastric outlet obstruction that was initially misdiagnosed as gastroparesis due to uncontrolled diabetes. This tumor did not present with the usual symptoms or as carcinoid syndrome, as it was negative for all tumor markers and metanephrines. Treatment typically includes preoperative administration of somatostatin analogs, however, these were not used as the tumor showed no evidence of hormone secretion.

Temporal variations in and predictive values of ABG results prior to in-hospital cardiac arrest.

In-hospital cardiac arrest (IHCA) has been understudied relative to out-of-hospital cardiac arrest. Further, studies of IHCA have mainly focused on a limited number of pre-arrest patient characteristics (e.g.

Extreme migratory connectivity and apparent mirroring of non-breeding grounds conditions in a severely declining breeding population of an Afro-Palearctic migratory bird.

Understanding the distribution of breeding populations of migratory animals in the non-breeding period (migratory connectivity) is important for understanding their response to environmental change. High connectivity (low non-breeding population dispersion) may lower resilience to climate change and increase vulnerability to habitat loss within their range. Very high levels of connectivity are reportedly rare, but this conclusion may be limited by methodology.

Dynamic neurocognitive adaptation in aging: Development and validation of a new scale.

Introduction: Forty-five percent of Alzheimer's disease (AD) cases may have been preventable through protective factors. Reserve, resilience, and resistance share common neurocognitive adaptive processes, acting through protective mechanisms. In this article we propose the development and validation of a new scale, called dynamic Neurocognitive Adaptation, developed in this direction.
