Purpose: Although it has been generally believed that parturients have delayed gastric emptying during anesthesia, the most recent reports suggest that gastric emptying is not delayed during pregnancy except during labor. Electrical slow waves in the stomach determine the frequency and the peristaltic nature of gastric contractions. In this study we performed electrogastrography during and after elective cesarean section (CS) in an attempt to evaluate gastric motility.
Methods: Sixteen American Society of Anesthesiologists physical status I or II term parturients undergoing elective CS were enrolled. Combined spinal-epidural anesthesia was initiated with 10 mg of bupivacaine plus 10 microg of fentanyl. Four-channel electrogastrography was obtained for 10 min prior to venous catheter insertion (baseline), 10 min following spinal injection of bupivacaine and fentanyl (Sp-1), 10 to 20 min following spinal injection (Sp-2), 10 min prior to the end of operation (end), and finally 10 min on the seventh postoperative day (POD 7).
Results: The mean +/- SD values for dominant frequency of electrogastrography (DF) were determined as: 1.57 +/- 0.36 cpm (baseline), 1.81 +/- 0.32 cpm (Sp-1), 2.08 +/- 0.36 cpm (Sp-2), 1.96 +/- 0.36 cpm (end), and 3.02 +/- 0.28 cpm (POD 7). The DF of Sp-1, Sp-2, and end were significantly higher than that of baseline (P < 0.05). The DF of POD 7 was significantly higher than that of baseline, Sp-1, Sp-2, and end (P < 0.01).
Conclusion: Electrogastrography analysis suggests that the frequency of gastric contractions during CS was less than that in the postpartum period.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous entity including patients with different phenotypes of near normal, normal, and supernormal left ventricular (LV) function.
Objectives: To assess the value of resting LV elastance (also known as force) with transthoracic echocardiography (TTE) to identify HFpEF phenotypes.
Methods: In a prospective, observational, multicenter study, 2380 HFpEF patients were recruited from July 2016 to May 2024.
Saffron has been traditionally used for various health benefits, but its effects on biomarkers of liver function, kidney function, and blood pressure in diabetes are not well understood. This meta-analysis aims to evaluate the impact of saffron supplementation on systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), liver enzymes (ALT, AST), and kidney function markers (BUN, creatinine) in patients with diabetes and prediabetes. A comprehensive search was conducted across multiple databases to identify randomized controlled trials (RCTs) assessing saffron/crocin supplementation on glycemic control, hepatic and renal function, and blood pressure regulation in patients with diabetes and prediabetes.

The presence of trace metals (TMs) in river systems at certain levels can cause toxicity and pose significant risks to human health. In this study, nine TMs (Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were determined by inductively coupled plasma optical emission spectrometry (ICP-OES) in water samples collected from six major rivers from southwestern Nigeria during both dry and wet seasons. Across both seasons, the mean concentrations (mg/L) ranged from 0.

Faecal cortisol metabolites (FCMs) are increasingly used to index physiological stress in wildlife. Cortisol and other stress hormones act to mobilize glucose, providing energy for the organism to respond to environmental perturbations. Cortisol, the predominant glucocorticoid (GC) in most mammals, is metabolized by the liver and excreted as FCMs.
