The effect of alpha-lipoic acid supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in individuals with polycystic ovary syndrome: a systematic review and meta-analysis of randomized clinical trials.

This systematic review and meta-analysis aimed to examine the effect of the antioxidant alpha-lipoic acid (ALA) on various cardiometabolic risk factors and hormonal parameters in patients with polycystic ovary syndrome (PCOS). We searched PubMed, EMBASE, SCOPUS, Cochrane Library, and Web of Science databases without language restrictions until May 2023 to find randomized controlled trials (RCTs) that assessed the impact of ALA supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in women with PCOS. Outcomes were summarized using the standardized mean difference (SMD) and 95% confidence interval (CI) in a random-effects model. An I2 statistic of >60% established significant between-study heterogeneity. The overall certainty of the evidence for each outcome was determined using the grading of recommendations, assessment, development, and evaluations system. Seven RCTs met the inclusion criteria. The ALA group had significant reductions in fasting blood sugar (fasting blood sugar (FBS), n=7 RCTs, SMD, -0.60; 95% CI, -1.10 to -0.10; I2=63.54%, moderate certainty of evidence) and homeostatic model assessment for insulin resistance (homeostatic model assessment of insulin resistance (HOMA-IR), n=4 RCTs, SMD, -2.03; 95% CI, -3.85 to -0.20; I2=96.32%, low certainty of evidence) compared with the control group. However, significant differences were observed between the groups in body mass index, insulin, estrogen, follicle-stimulating hormone, luteinizing hormone, testosterone, low-density lipoprotein, highdensity lipoprotein, triglyceride, total cholesterol, malondialdehyde, or total antioxidant capacity profiles. ALA supplementation improves FBS and HOMA-IR levels in women with PCOS. ALA consumption is an effective complementary therapy for the management of women with PCOS.

Intraoperative local injection of uterosacral ligaments with ropivacaine during uterine surgery: A systematic review and meta-analysis of randomized controlled trials.

AIM: To perform a systematic review and meta-analysis of all randomized controlled trials that examined the efficacy of intraoperative local injection of the uterosacral ligaments with ropivacaine on postoperative pain and opioids consumption in patients undergoing uterine surgery for hysterectomy/myomectomy. METHODS: PubMed, Scopus, Web of Science and Cochrane Library databases were screened from inception to September 5th, 2020. We appraised the risk of bias using the Cochrane's risk of bias tool. Resting postoperative pain scores and cumulative consumption of postoperative opioids were regarded as continuous data, analyzed using the inverse variance method and reported as standardized mean difference (SMD) and weighted mean difference (MD), respectively, with 95 % confidence intervals (95 % CIs). RESULTS: Five studies met the inclusion criteria comprising 230 patients (117 and 113 patients received ropivacaine and placebo, respectively). The studies had an overall low risk of bias. Resting postoperative pain scores were not significantly different between both groups at 2 h (SMD = -0.30, 95 % CI [-0.70, 0.11], p = 0.15), 12 h (SMD = 0.04, 95 % CI [-0.26, 0.37], p = 0.81) and 24 h (SMD = -0.06, 95 % CI [-0.32, 0.20], p = 0.68). However, the ropivacaine group had significantly reduced cumulative opioid consumption during the first 24 h postoperatively (MD = -9.07, 95 % CI [-14.47, -3.66], p = 0.001). CONCLUSION: Intraoperative local infiltration of uterosacral ligaments with ropivacaine is technically feasible and significantly reduces postoperative opioid consumption in women undergoing gynecologic surgery of the uterus.

Ropivacaine versus lidocaine infiltration for postpartum perineal pain: A systematic review and meta-analysis.

AIM: To systematically and meta-analytically examine the efficacy of ropivacaine versus lidocaine infiltration for controlling postpartum perineal pain secondary to spontaneous tear or selective episiotomy. METHODS: We searched four databases from inception to 20-September-2020. We included all relevant randomized and nonrandomized studies and assessed their risk of bias. We pooled data as standardized mean difference (SMD), weighted mean difference (WMD), or odds ratio (OR) with 95 % confidence intervals (95 % CIs). RESULTS: Four studies met the inclusion criteria (one and three studies were nonrandomized and randomized, respectively). There were 405 patients; 205 and 200 patients received lidocaine and ropivacaine, respectively. There was no significant difference between ropivacaine and lidocaine groups with regard to visual analogue scale (VAS) pain scores at suturing (WMD = -0.04, 95 % CI [-0.41, 0.32], P = 0.82), 2 h (SMD = -1.50, 95 % CI [-3.50, 0.50], P = 0.14), and 24 h (SMD = -0.40, 95 % CI [-1.15, 0.34], P = 0.29) post repair of perineal trauma. Proportion of patients with mild VAS pain score ≤3 at 24 h was significantly higher in the ropivacaine group (OR = 4.34, 95 % CI [2.03, 9.29], P < 0.001). Proportion of patients who did not require additional analgesia during the first 24 h post perineal repair did not significantly differ between both groups (OR = 2.44, 95 % CI [0.09, 68.21], P = 0.60). Ropivacaine group achieved higher maternal satisfaction (OR = 7.13, 95 % CI [3.63, 13.99], P < 0.001). CONCLUSIONS: During repair of postpartum perineal trauma, pain efficacy is relatively longer with ropivacaine but safety is not well investigated. High-quality and large-sized studies are needed to consolidate these findings.
