Association of Gut Microbiota With Fatigue in Black Women With Polycystic Ovary Syndrome.

Background: Fatigue is a highly prevalent symptom for individuals with polycystic ovary syndrome (PCOS); however, characterization of fatigue and investigation into the gut microbiome-a pathway that may contribute to fatigue-remains inadequately explored in Black women with PCOS.

Objectives: The purpose of this cross-sectional study was to examine fatigue and its relationship to the gut microbiome in adult Black women with PCOS.

Methods: Adult Black women with a diagnosis of PCOS were recruited for this cross-sectional study.

Intravenous administration of quinidine and metoprolol for treatment of atrial fibrillation in 2 neonatal foals.

Atrial fibrillation (AF) is a rarely reported arrhythmia in otherwise healthy newborn foals, with a single case of cardioversion using procainamide administration described in the literature. Two neonatal Thoroughbred colts were presented to an equine hospital because of an irregularly irregular tachyarrhythmia and poor latching when trying to nurse. History, physical examination, and initial diagnostic testing including ECG and echocardiography confirmed AF without structural heart disease.

The mediating effect of maternal gut microbiota between prenatal psychological distress and neurodevelopment of infants.

Background: Prenatal psychological distress and maternal inflammation can increase the risk of neurodevelopmental delay in offspring; recently, the gut microbiota has been shown to may be a potential mechanism behind this association and not fully elucidated in population study.

Methods: Seventy-two maternal-infant pairs who completed the assessments of prenatal psychological distress during the third trimester and neurodevelopment of infants at age 6-8 months of age were included in this study. The gut microbiota and its short-chain fatty acids (SCFAs) of maternal-infant were determined by 16S rRNA sequencing and liquid chromatography-mass spectrometry analysis.

Ultrasound-guided caudal cervical articular process arthrocentesis is accurate in live horses with and without arthropathy.

Background: Cervical articular process joint (CAPJ) therapy is advocated for horses with neck disorders. Several ultrasound-guided CAPJ techniques have been described in cadaver studies with 72%-89% intra-articular injection accuracy; however, the CAPJ injection accuracy in clinical equine practice has not been extensively reported.

Objectives: To describe a modified cranial approach for ultrasound-guided caudal CAPJ injections, to investigate the accuracy of this CAPJ injection technique in live horses, and to assess the effect of CAPJ injection location, laterality, operator, and radiographic CAPJ enlargement on injection accuracy.
