Objective: To study the effect of a 50 mg caffeine coffee consumption on bowel function recovery after cesarean delivery. Materials and Methods: A randomized controlled trial was conducted. One hundred sixty-two post-cesarean delivery patients were enrolled and allocated to one of the two groups, Group 1, which included 81 volunteers, with a cup of 50 mg caffeine coffee and Group 2, which also included 81 volunteers, with a cup of warm water at postpartum ward, two hours after the operation. The primary outcome was to compare the time to first flatus after surgery between patients of each group. The secondary outcome was to compare the time to first defecation, time to tolerate a solid diet, and the incidence of postoperative ileus between groups. Results: The mean time to first flatus and standard deviation was 28.93±20.20 and 30.52±16.27 hours, time to first defecation was 62.45±28.00 and 63.45±25.53 hours, and the incidence of postoperative ileus was 17.28% and 19.75%. All results in both groups were not significantly different in the 50 mg caffeine coffee group and the warm water group. Conclusion: Drinking coffee with a cup of 50 mg caffeine coffee after cesarean delivery did not significantly improve the bowel function recovery. The higher dosage of caffeine coffee needs further studies. [ABSTRACT FROM AUTHOR]

Objective: To study the incidence and factors associated with inadequate endometrial tissue for pathological evaluation from uterine curettage in patients with abnormal uterine bleeding (AUB) at Udon Thani Hospital. Materials and Methods: The electronic medical records of women aged 35 years and older with AUB that underwent endometrial curettage in a regional hospital between October 2018 and November 2019 were retrospectively reviewed. The incidence of inadequate endometrial tissue for pathological evaluation was studied. Multiple logistic regression analysis was performed to determine the factors associated with inadequate curettage. Results: Three hundred fifty-two patients with AUB that underwent endometrial tissue curettage and had complete medical records were included in the present study. The mean age was 48.09±8.01 years. The incidence of inadequate endometrial tissue for pathological evaluation was 23.30% (95% CI 18.98 to 28.07). Postmenopausal status (adjusted OR 3.80, 95% CI 1.93 to 7.50), the low experience of the clinician (adjusted OR 2.20, 95% CI 1.15 to 3.87), and the uterine cavity length measured by uterine sound (adjusted OR 0.66 for each 1 cm increment, 95% CI 0.54 to 0.80) were significant factors associated with inadequate tissue for pathological evaluation. Conclusion: The incidence of inadequate endometrial tissue for pathological evaluation from endometrial curettage was one-quarter of all cases. The associated factors of inadequate endometrial tissue included postmenopausal status, inexperience operators, and shorter uterine length. [ABSTRACT FROM AUTHOR]
