Perioperative Near Infrared Spectroscopy Measurements of Cerebral Regional Oxygen Desaturations Are Not Associated With Delirium After Cardiac Surgery.

Objective: Postoperative delirium remains a common complication after cardiac surgery in high-risk patients and has been associated with prolonged intensive care unit length of stay, overall morbidity, and mortality. It has been proposed that cerebral hypoperfusion is an important etiological component. In the present study, we retrospectively queried intraoperative near-infrared spectroscopy measurements of regional cerebral oxygen saturations (rSO) during adult cardiac surgical procedures to examine the association between rSO desaturations and postoperative delirium.

Health Care Professional Adherence to Breast Cancer Management Guidelines in Nigeria.

Importance: In Nigeria, 80% of breast cancer is diagnosed at an advanced stage, when clinical management is complex and necessitates multidisciplinary collaboration. The Nigerian Federal Ministry of Health promotes multidisciplinary tumor board (MDT) discussions and endorses the National Comprehensive Cancer Network Harmonized Guidelines for Sub-Saharan Africa (Harmonized Guidelines) to standardize breast cancer care, but the extent of their clinical utilization is not well understood.

Objective: To identify barriers to and facilitators of the standardization of breast cancer care in Nigeria as reflected by awareness and consultation of resource-adapted guidelines.

Genomics yields biological and phenotypic insights into bipolar disorder.

Bipolar disorder is a leading contributor to the global burden of disease. Despite high heritability (60-80%), the majority of the underlying genetic determinants remain unknown. We analysed data from participants of European, East Asian, African American and Latino ancestries (n = 158,036 cases with bipolar disorder, 2.

Ablation of satellite cell-specific clock gene, Bmal1, alters force production, muscle damage, and repair following contractile-induced injury.

Following injury, skeletal muscle undergoes repair via satellite cell (SC)-mediated myogenic progression. In SCs, the circadian molecular clock gene, Bmal1, is necessary for appropriate myogenic progression and repair with evidence that muscle molecular clocks can also affect force production. Utilizing a mouse model allowing for inducible depletion of Bmal1 within SCs, we determined contractile function, SC myogenic progression and muscle damage and repair following eccentric contractile-induced injury.
