RESUMO

OBJECTIVES: Since 2020, with the entire world in crisis over the coronavirus pandemic (COVID-19), medical students have adapted to hybrid and distance learning. This study aims to compare the learning outcomes of students learning the procedure of fractional curettage in an online video-assisted teaching program to those of students learning the procedure in a traditional class. METHODS: A quasi-experimental study was conducted among fourth-year medical students who rotated to Obstetrics and Gynecology courses between April 2021 and October 2021. Participants in the first two rotations were enrolled in traditional classes, and the online video-assisted teaching program was introduced in the subsequent two rotations. Both study groups took OSCEs (objective structured clinical examinations), a pre-test and post-test with MCQs (multiple choice questions), and a confidence and satisfaction level questionnaire. RESULTS: A total of 106 fourth-year medical students, 54 in the traditional group and 52 in the online video-assisted teaching program, were recruited. The online video-assisted group showed a statistically better mean OSCE score (85.67 ± 11.29 vs. 73.87 ± 13.01, p < 0.001) and mean post-test MCQ score than the traditional group (4.21 ± 0.87 vs. 3.80 ± 0.98, p = 0.0232). Moreover, the mean difference between the two groups' pre and post-test MCQ scores was significantly different (0.96 ± 1.37 vs. 1.79 ± 1.50 in traditional and online video-assisted teaching program groups, respectively, P = 0.0038). The participants in the experimental group reported significantly greater confidence (P < 0.001) in performing the fractional curettage procedure. However, the mean satisfaction score was significantly higher in the control group (p = 0.0053). CONCLUSION: The online video-assisted teaching program on the fractional curettage procedure, a necessary and skill-demanding procedure, is an effective and advantageous education tool that improves skills, knowledge, and confidence in fourth-year medical students. We recommend that the video-assisted teaching program is another effectively procedural teaching method for medical students.

RESUMO

The objective of this study was to investigate the incidence of gastrointestinal injuries during gynaecologic operations, the management of such injuries and associated risk factors. This case-control study (1:4) examined patients who received gynaecologic operations from 2007 to 2016 in Ramathibodi Hospital. The study cases comprised patients who had gastrointestinal injuries, while the control cases comprised patients who had gynaecologic surgeries in the same period with matching the types of procedures. The 10-year incidence was 0.38% (104 cases of gastrointestinal injuries among a total of 27,520 cases). The most common injury site was the small bowel (43.3%). There were 102 cases (98%) of gastrointestinal injuries which were diagnosed intraoperatively and which were immediately repaired with successful outcomes. Logistic regression indicated that a pelvic adhesion, previous pelvic surgery and previous abdominal surgery were predictive risk factors associated with the injuries (odds ratios: 9.45, 3.20 and 11.84, respectively). An immediate consultation with a surgeon and surgical repair of the injury resulted in excellent outcomes. Impact statement What is already known about this subject? Gastrointestinal injury is a rare, but fatal complication of gynaecologic operations. The previous small study identified some risk factors such as surgical approach and pelvic surgery associated with the injury. What do the results of this study contribute? Our study identified the associated risk factors for gastrointestinal injury, including previous abdominal injury, pelvic adhesion and previous pelvic surgery. A previous abdominal surgery was the most associated risk factor. Patients with the history of abdominal surgery had an almost 4-fold higher odds ratio than the ones with previous pelvic surgery. Other factors, including endometriosis, ovarian cancer and subsequent oncological procedures, and surgical staging were less related to the gastrointestinal injury. What are the implications of these findings for clinical practice and/or further research? The knowledge is useful for pre-operative evaluation and preparation. Bowel preparation and consultation with surgeon are necessary for patients with these risk factors prior to their surgeries. Moreover, an immediate intra-operative surgical correction of the injury results in excellent outcomes.

RESUMO

Polycystic ovarian syndrome (PCOS) is a common and complex condition characterized by endocrine features and influenced by genetic and environmental factors. In Southeast Asia and Thailand, the prevalence of PCOS is unknown. The aim of this study was to estimate the prevalence of and determine factors associated with PCOS in Thai adolescents. We administered a validated questionnaire to 600 university female participants aged 17-19 years from Mahidol University in Bangkok. Of these, 548 (91.33%) responded and agreed to participate. Two-hundred and seventy-nine girls (50.91%) were identified as likely having PCOS and defined as 'probable cases'. Of those 279 participants, 248 (88.88%) were evaluated further for PCOS using the Rotterdam criteria. A complete history was taken, and a physical examination including trans-abdominal ultrasound was performed. Blood chemistry tests were performed to exclude similar conditions and to investigate potential co-morbidities. The prevalence of PCOS in Thai adolescents was found to be 5.29%. After multivariate analyses, moderate acne was the strongest risk factor for PCOS. The odd ratios (95% confidence interval) for the presence of mild acne, moderate acne, and oligo- or amenorrhea in participants with PCOS were 2.83 (1.01-7.90; p = .47), 31.69 (10.07-99.67; p < .001), and 5.89 (2.42-14.37; p < .001), respectively.

RESUMO

Probiotics have been found to have beneficial effects on bone metabolism. In this randomized, double-blind, placebo-controlled trial, the effects of multispecies probiotic supplementation on bone turnover markers were evaluated after 12 weeks. Forty postmenopausal women with osteopenia were included and randomly divided into two groups. The intervention group received multispecies probiotics, while the control group received identical placebo sachets daily. The baseline characteristics of both groups were similar. Still, the median serum bone resorption marker C-terminal telopeptide of type I collagen (CTX) was slightly higher in the multispecies probiotic group than in the placebo group (0.35 (0.12, 0.53) vs. 0.16 (0.06, 0.75); p-value = 0.004). After 12 weeks, the mean difference in serum CTX at baseline versus 12 weeks was significantly different between the multispecies probiotic and placebo groups (-0.06 (-0.29, 0.05) vs. 0.04 (-0.45, 0.67); p-value < 0.001). The multispecies probiotic group showed a significant decrease in serum CTX at 12 weeks compared with baseline (p-value 0.026). However, the placebo group showed no significant change in serum CTX (p-value 0.18). In conclusion, multispecies probiotics may have a preventive effect on bone through their antiresorptive effect in osteopenic postmenopausal women.

RESUMO

The Thai Menopause Society is an academic organization consisting of healthcare professionals engaged in menopause medicine. The position statement was first issued in 1994 and updated in 2003 and 2023. Herein, we reviewed the important updates of the 2023 position statement on menopausal hormone therapy (MHT) as an international reference for healthcare professionals in Thailand. An advisory panel of clinicians and research experts in the field of menopause reviewed the recommendation of published International Consensus Statements and updated the evidence using the MEDLINE database through PubMed. The evidence-based information and relevant publications were assessed, and a consensus on recommendations was subsequently achieved using the level of evidence to determine the recommendation strength and evidence quality. MHT remains the most effective treatment for vasomotor symptoms and genitourinary syndromes of menopause even after 20 years. Additionally, it is effective in preventing bone loss and fractures in postmenopausal women. The cardiovascular risk of MHT increased in women who initiated MHT after 60 years of age. Hormone therapy should be individualized following the hormone type, dose, administration route, use duration, and progestogen inclusion. The necessary pretreatment evaluation and appropriate follow-up recommendations were added for improved MHT standard care. The updated 2023 Clinical Practice Guideline on MHT is useful for gynecologists, general physicians, endocrinologists, and other healthcare professionals in treating menopausal women receiving hormone therapy in Thailand.

RESUMO

Chronic insomnia disorder is one of the most common problems in postmenopausal women, exacerbated by underdiagnosis and improper treatment. This double-blinded, randomized, placebo-controlled trial was conducted to evaluate the potential of vitamin E to treat chronic insomnia as an alternative to sedative drugs and hormonal therapy. The study enrolled 160 postmenopausal women with chronic insomnia disorder, divided randomly into two groups. The vitamin E group received 400 units of mixed tocopherol daily, while the placebo group received an identical oral capsule. The primary outcome of this study was sleep quality assessed by the Pittsburgh Sleep Quality Index (PSQI), a self-evaluated and standardized questionnaire. The secondary outcome was the percentage of participants using sedative drugs. There were no significant differences in baseline characteristics between the study groups. However, the median PSQI score at baseline was slightly higher in the vitamin E group compared with the placebo (13 (6, 20) vs. 11 (6, 20); p-value 0.019). After one month of intervention, the PSQI score was significantly lower (indicating better sleep quality) in the vitamin E group compared with the placebo (6 (1, 18) vs. 9 (1, 19); p-value 0.012). Moreover, the improvement score was significantly higher in the vitamin E group compared with the placebo (5 (-6, 14) vs. 1 (-5,13); p-value < 0.001). In addition, there was a significant reduction in the percentage of patients using sedative drugs in the vitamin E group (15%; p-value 0.009), while this reduction was not statistically significant in the placebo group (7.5%; p-value 0.077). This study demonstrates vitamin E's potential as an excellent alternative treatment for chronic insomnia disorder that improves sleep quality and reduces sedative drug use.

RESUMO

Vitamin E is a strong anti-oxidative stress agent that affects the bone remodeling process. This study evaluates the effect of mixed-tocopherol supplements on bone remodeling in postmenopausal osteopenic women. A double-blinded, randomized, placebo-controlled trial study was designed to measure the effect of mixed-tocopherol on the bone turnover marker after 12 weeks of supplementation. All 52 osteopenic postmenopausal women were enrolled and allocated into two groups. The intervention group received mixed-tocopherol 400 IU/day, while the control group received placebo tablets. Fifty-two participants completed 12 weeks of follow-up. Under an intention-to-treat analysis, vitamin E produced a significant difference in the mean bone resorption marker (serum C-terminal telopeptide of type I collagen (CTX)) compared with the placebo group (-0.003 ± 0.09 and 0.121 ± 0.15, respectively (p < 0.001)). In the placebo group, the CTX had increased by 35.3% at 12 weeks of supplementation versus baseline (p < 0.001), while, in the vitamin E group, there was no significant change of bone resorption marker (p < 0.898). In conclusion, vitamin E (mixed-tocopherol) supplementation in postmenopausal osteopenic women may have a preventive effect on bone loss through anti-resorptive activity.

RESUMO

BACKGROUND: Strategies to preserve ovarian function after ovarian endometriotic cyst removal have been reported in many studies; however, no study has evaluated tranexamic acid administration during surgery. OBJECTIVE: To evaluate feasibility of conducting a definitive trial and assessing the potential efficacy of tranexamic acid on ovarian reserve and intra-operative blood loss by comparing mean differences in anti-Müllerian hormone (AMH) levels following laparoscopic ovarian cystectomy between tranexamic acid and control groups. MATERIALS AND METHODS: A parallel two-arm pilot trial was conducted with 40 participants with endometriotic cysts who underwent laparoscopic ovarian cystectomy. They were randomized 1:1 to either 1 g tranexamic acid (TXA) or no TXA (n = 20 per group). TXA was administered to the participants immediately after induction of general anesthesia and intubation. The primary outcome was the feasibility of conducting a definitive trial in terms of design and procedures (such as recruitment rate, retention, safety of intravenous 1 gm of TXA, sample size verification) and assess the efficacy of TXA on the ovarian reserve and intra-operative blood loss by comparing mean difference of AMH levels between TXA and control groups at pre- and 3 months post-surgery. RESULTS: The recruitment and successful completion rates were 95% and 100%. Baseline characteristics were similar in the two groups. The mean difference of serum AMH levels (pre- and 3 months post-surgery) between the TXA and control groups was not significantly different. When performing a subgroup analysis, the mean difference of AMH levels (pre- and 3 months post-surgery) seemed to be higher in the bilateral than in the unilateral ovarian cyst group but not significantly different. Operating time was significantly longer in bilateral than in unilateral cysts. No post-operative complications or adverse effects were found. CONCLUSION: The full randomized controlled trial for evaluating effects of TXA administration during laparoscopic cystectomy for endometrioma on ovarian reserve was shown to be feasible. Several modifications should be added for improving feasibility, for example, increasing the TXA dose, modifying TXA administration, focusing on either patients with unilateral or bilateral ovarian cysts, and exploring other outcome measures, e.g., surgeons' satisfaction.

RESUMO

The effects of oral vitamin D supplements on vaginal health in postmenopausal women with vulvovaginal atrophy (VVA) was evaluated. A double-blinded, randomized placebo-controlled trial was conducted for 12 weeks to investigate changes on vaginal maturation index (VMI), vaginal pH, and the visual analog scale (VAS) of VVA symptoms. The vitamin D group received oral ergocalciferol, at 40,000 IU per week, while the placebo group received an identical placebo capsule. Eighty postmenopausal women were enrolled. There were no significant differences in baseline characteristics between both groups. In an intention-to-treat analysis, VMI, vaginal pH, and VAS of VVA symptoms showed no significant differences between both groups at the six and 12 weeks. However, the mean difference of VMI in the vitamin D group between baseline and at six weeks showed significant improvement (5.5 + 16.27, p <0.05). Moreover, the mean vaginal pH and VAS of VVA patients in the vitamin D group were significantly improved at both six and 12 weeks compared to baseline. The oral vitamin D supplementation for 12 weeks potentially improves vaginal health outcomes in postmenopausal women with VVA symptoms, demonstrated by the improved mean VMI, vaginal pH, and VAS at six and 12 weeks between baseline, however, no significant differences were observed from the placebo treatment.

RESUMO

Polycystic ovary syndrome (PCOS) and nonalcoholic fatty liver (NAFLD) share similar clinical presentations including obesity, insulin resistance (IR), and metabolic abnormality. The predictive factors of NAFLD in women with PCOS and specifically in Asian women are not well established. Associated factors for NAFLD assessed by ultrasound (US) among a group of PCOS and healthy women were determined and diagnostic accuracy between US and transient elastography (TE) for NAFLD was compared and correlated. Sixty-three women with ages ranging from 20 to 40 years participated in the present cross-sectional study. Forty-two women with PCOS as diagnosed by the Rotterdam criteria and 21 healthy women were recruited into the study. Women with underlying hepatic diseases and history of alcohol consumption >20 g/day were excluded. Biochemical and hormonal testing, anthropometrics, liver US, and TE were assessed. Waist circumference (WC) greater than 80 cm was the only predictive factor for NAFLD as assessed by US in the whole group (adjusted odds ratio [aOR] 5.49, 95% confidence interval [CI]: 1.85-16.26, p <0.001). The value of the TE-based controlled attenuation parameter (CAP) was significantly correlated with stage of steatosis as assessed by US (correlation coefficient = 0.696, p <0.001). The diagnostic accuracies of dichotomized CAP ≥236 dB/m assessed for NAFLD using US as the gold standard were 84% and 78% sensitivity and specificity, respectively, with the area under the curve at 0.81 (p <0.001). Abdominal obesity, rather than the presence of PCOS, was shown to be the independently associated factor for NAFLD. WC could be used as the primary screening tool before performing complicated intervention for detection of steatosis. TE is an alternative noninvasive detection tool in women with PCOS for NAFLD and hepatic fibrosis identification.

RESUMO

Vitamin D supplementation effects with or without calcium in pregnancy for reducing risk of preeclampsia and gestational or pregnancy induced hypertension are controversial. Literature was systematically searched in Medline, Scopus and Cochrane databases from inception to July 2017. Only randomized controlled trials (RCTs) in English were selected if they had any pair of interventions (calcium, vitamin D, both, or placebo). Systematic review with two-step network-meta-analysis was used to indirectly estimate supplementary effects. Twenty-seven RCTs with 28,000 women were eligible. A direct meta-analysis suggested that calcium, vitamin D, and calcium plus vitamin D could lower risk of preeclampsia when compared to placebo with the pooled risk ratios (RRs) of 0.54 (0.41, 0.70), 0.47 (0.24, 0.89) and 0.50 (0.32, 0.78), respectively. Results of network meta-analysis were similar with the corresponding RRs of 0.49 (0.35, 0.69), 0.43 (0.17, 1.11), and 0.57 (0.30, 1.10), respectively. None of the controls were significant. Efficacy of supplementation, which was ranked by surface under cumulative ranking probabilities, were: vitamin D (47.4%), calcium (31.6%) and calcium plus vitamin D (19.6%), respectively. Calcium supplementation may be used for prevention for preeclampsia. Vitamin D might also worked well but further large scale RCTs are warranted to confirm our findings.
