RESUMEN
OBJECTIVE: This study aimed to systematically examine the relationship between polycystic ovary syndrome and ovarian, endometrial, and cervical cancers using the National Inpatient Sample (NIS) database. METHODS: We utilized the International Classification of Diseases (ICD-10) system to identify relevant codes from the NIS database (2016-2019). Univariate and multivariable regression analyses (adjusted age, race, hospital region, hospital teaching status, income Zip score, smoking, alcohol use, and hormonal replacement therapy) were conducted to evaluate association between PCOS and gynecologic cancers. Results were summarized as odds ratio (OR) with 95% confidence intervals (CI). RESULTS: Overall, 15,024,965 patients were analyzed, of whom 56,183 and 14,968,782 patients were diagnosed with and without PCOS, respectively. Among the patients diagnosed with gynecologic cancers (n = 91,599), there were 286 with PCOS and 91,313 without PCOS. Univariate analysis revealed that PCOS was significantly associated with higher risk of endometrial cancer (OR = 1.39, 95 % CI [1.18-1.63], p < 0.0001), but lower risk of ovarian cancer (OR = 0.55, 95 % CI [0.45-0.67], p < 0.0001) and cervical cancer (OR = 0.68, 95 % CI [0.51-0.91], p = 0.009). In contrast, after Bonferroni correction, multivariable analysis depicted that PCOS remained significantly associated with higher risk of endometrial cancer (OR = 3.90, 95 % CI [4.32-4.59], p < 0.0001). There was no significant correlation between PCOS and risk of ovarian cancer (OR = 1.09, 95 % CI [0.89-1.34], p = 0.409) and cervical cancer (OR = 0.83, 95 % CI [0.62-1.11], p = 0.218). CONCLUSION: This first-ever NIS analysis showed that patients with PCOS exhibited unique gynecologic cancer risk profiles, with higher risk for endometrial cancer, and no significant risk for ovarian or cervical cancers.

OBJECTIVE: We investigated the potential relationship between endometriosis and risk of ovarian, endometrial, cervical, and breast cancers using the National Inpatient Sample (NIS) database. METHODS: We utilized the International Classification of Diseases (ICD-10) system to identify relevant codes from the NIS database (2016-2019). Univariate and multivariate regression analyses (adjusted for age, race, hospital region, hospital teaching status, income Zip score, smoking, alcohol use, and hormonal replacement therapy) were conducted to evaluate the association between endometriosis and gynecologic cancers and summarized as odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: In the examined dataset, there were 1164 and 225,323 gynecologic cancer patients with and without endometriosis, respectively. Univariate analysis showed endometriosis was significantly associated with a higher risk of ovarian (OR = 3.42, 95% CI: 3.05-3.84, p < 0.001) and endometrial (OR = 3.35, 95% CI: 2.97-3.79, p < 0.001) cancers. There was no significant association between endometriosis and cervical cancer (OR = 1.05, 95% CI: 0.85-1.28, p = 0.663). Interestingly, endometriosis was significantly associated with a low risk of breast cancer (OR = 0.12, 95% CI: 0.10-0.17, p < 0.001). Multivariate analysis after Bonferroni correction (p < 0.006) showed that endometriosis was significantly associated with a high risk of ovarian (adjusted OR = 3.34, 95% CI: 2.97-3.75, p < 0.001) and endometrial (adjusted OR = 3.61, 95% CI: 3.12-4.08, p < 0.001) cancers. Conversely, there was no significant association between endometriosis and cervical cancer (OR = 0.80, 95% CI: 0.65-0.99, p = 0.036). CONCLUSIONS: Patients with endometriosis exhibited unique gynecologic cancer risk profiles, with higher risks for ovarian and endometrial cancers, and no significant risk for cervical cancer. The observed connection between endometriosis and a reduced risk of breast cancer remains a perplexing phenomenon, which cannot be put into context to date.

AIM: To conduct the first-ever systematic review and meta-analysis of randomized controlled trials (RCTs) on the antihemorrhagic utility and safety of tranexamic acid (TXA) versus misoprostol for management (prevention and/or treatment) of postpartum hemorrhage (PPH). METHODS: Six databases were screened from inception until May 2023 and updated in September 2023. The RCTs were assessed for quality according to the Cochrane's risk of bias tool. The endpoints were summarized as mean difference (MD) or risk ratio (RR) with 95% confidence interval (CI) in a random-effects model. RESULTS: Ten RCTs with 2121 patients (TXA = 1061 and misoprostol = 1060) were analyzed. There was no significant difference between TXA and misoprostol groups regarding the mean intraoperative blood loss (n = 9 RCTs, MD = 17.32 ml, 95% CI [-40.43, 75.07], p = 0.56), mean change in hemoglobin (n = 6 RCTs, MD = 0.11 mg/dl, 95% CI [-0.1, 0.31], p = 0.30), mean hospital stay (n = 2 RCTs, MD = -0.3 day, 95% CI [-0.61, 0.01], p = 0.06), blood transfusion rate (n = 4 RCTs, RR = 0.49, 95% CI [0.16, 1.47], p = 0.2), and rate of additional uterotonic agents (n = 4 RCTs, RR = 1.05, 95% CI [0.72, 1.53], p = 0.81). Leave-one-out sensitivity analysis showed robustness of the results, and there was no evidence of publication bias. Regarding safety endpoints, there was no significant difference between both groups regarding the rates of minor side effects, such as diarrhea, fever, nausea, and vomiting. No patient developed thromboembolic events in the TXA group. CONCLUSION: There was no significant antihemorrhagic efficacy between adjunct TXA and misoprostol for the management of PPH. The safety profile was comparable between both agents.

Background and Objectives: Abdominal hysterectomy is a major surgery that is often associated with pronounced postsurgical pain. The objective of this research is to conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) and nonrandomized comparative trials (NCTs) that have surveyed the analgesic benefits and morbidity of intraoperative superior hypogastric plexus (SHP) block (intervention) compared with no SHP block (control) during abdominal hysterectomy. Materials and Methods: The Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar, Web of Science, PubMed, Scopus, and Embase were searched from inception until 8 May 2022. The Cochrane Collaboration tool and Newcastle-Ottawa Scale were used to evaluate the risk of bias of RCTs and NCTs, respectively. In a random effects mode, the data were pooled as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). Results: Five studies (four RCTs and one NCT) comprising 210 patients (SHP block = 107 and control = 103) were analyzed. The overall postsurgical pain score (n = 5 studies, MD = -1.08, 95% CI [-1.41, -0.75], p < 0.001), postsurgical opioid consumption (n = 4 studies, MD = -18.90 morphine milligram equivalent, 95% CI, [-22.19, -15.61], p < 0.001), and mean time to mobilization (n = 2 studies, MD = -1.33 h, 95% CI [-1.98, -0.68], p < 0.001) were significantly decreased in the SHP block group contrasted with the control arm. Nevertheless, there was no significant variance between both arms regarding operation time, intraoperative blood loss, postsurgical NSAID consumption, and hospital stay. There were no major side effects or sympathetic block-related aftermaths in both groups. Conclusions: During abdominal hysterectomy and receiving perioperative multimodal analgesia, the administration of intraoperative SHP block is largely safe and exhibits better analgesic effects compared to cases without administration of SHP block.

INTRODUCTION: Immunogenicity has emerged as a challenge in the development of vaccines against coronavirus disease of 2019 (COVID-19). Immunogenicity is a determinant of the efficacy and safety of vaccines. This systematic review and associated meta-analysis summarized and characterized the immunogenicity of COVID-19 vaccines in randomized controlled trials (RCTs). METHODS: Relevant RCTs were systematically sourced from different medical databases in August 2021. The risk ratios and mean differences with 95% confidence intervals were calculated. RESULTS: Of 2,310 papers, 16 RCTs were eligible for review. These RCTs involved a total of 26,698 participants (15,292 males and 11,231 females). The pooled results showed a significant difference in the geometric mean titer between the vaccinated and control groups in favor of the vaccine group after 1 and 2 months of follow-up, for the young age group (18 - < 55y), and with different doses (P < 0.001). The difference in the older age group (>55y) was insignificant (P = 0.24). The seroconversion rate of spike neutralizing antibodies favored the vaccine groups 1 or 2 months after vaccination (P < 0.001). The seroconversion rate of the vaccine group was significantly different (P < 0.001) from that of the control group. CONCLUSIONS: Vaccination elicits immunogenicity in the follow-up period for all age groups and at low and large doses. Therefore, people should be encouraged to receive vaccines currently being offered. A boost dose has been asserted for the elderly.

RESUMEN
OBJECTIVE: To collate evidence from randomized controlled trials (RCTs) and nonrandomized controlled trials (NCTs) on the efficacy and safety of vasopressin versus passive control (placebo/no treatment) during myomectomy. METHODS: Six information sources were screened until 25-June-2022. The Cochrane Collaboration tool and Newcastle-Ottawa Scale were used to evaluate the risk of bias. Data were summarized as mean difference or risk ratio with 95% confidence interval in a random-effects model. RESULTS: Eleven studies, comprising 1067 patients (vasopressin=567 and control=500) were analyzed. For RCTs (n = 8), the overall quality included 'high risk' (n = 4), 'low risk' (n = 2), and 'some concerns' (n = 2). For NCTs (n = 3), the overall quality included 'good' (n = 2) and 'fair' (n = 1). The mean intraoperative blood loss, mean difference in hemoglobin level, mean difference in hematocrit level, rate of perioperative blood transfusion, and mean operative time were significantly reduced in favor of the vasopressin group compared with the control group. However, there was no significant difference between both groups regarding the mean hospital stay. Pertaining to safety endpoints, after omission of an outlier study, the rate of drug-related cardiovascular adverse events did not significantly differ between both groups. There was no quantitative evidence of publication bias for the endpoint of intraoperative blood loss. CONCLUSION: Among patients undergoing myomectomy, prophylactic administration of vasopressin was largely safe and correlated with significant reductions in intraoperative blood loss and associated morbidities compared with a passive control intervention. Nonetheless, the conclusions should be cautiously interpreted owing to the low-evidence quality and the used doses varied greatly between studies.

PURPOSE: We aimed to investigate the impact of anastrozole administration on the traditional components of the lipid profile (ie, total cholesterol [TC], LDL-C, HDL-C, and triglycerides [TGs]) by means of a systematic review and meta-analysis of randomized controlled trials. METHODS: We searched the PubMed/Medline, Scopus, Embase, and Web of Science databases for relevant randomized controlled trials published in the English language until January 18, 2022. The weighted mean difference (WMD) and 95% CIs were calculated using a random-effects model (DerSimonian and Laird methods). FINDINGS: Anastrozole administration significantly lowered TC concentrations when the treatment duration was ≤3 months (WMD = -2.73 mg/dL; 95% CI, -5.09 to -0.38 mg/dL; P = 0.02) and when the baseline TC concentration was ≥200 mg/dL (WMD = -3.64 mg/dL; 95% CI, -6.30 to -0.98 mg/dL; P = 0.007). HDL-C levels decreased after anastrozole administration when the treatment duration was >3 months (WMD = -1.67 mg/dL; 95% CI, -3.24 to -0.10 mg/dL; P = 0.03). Anastrozole administration had no impact on TG or LDL-C values. IMPLICATIONS: Anastrozole administration in humans can decrease TC and HDL-C levels but has no effect on LDL-C or TG concentrations.

To perform a systematic review and meta-analysis of all randomized controlled trials (RCTs) that evaluated the efficacy and safety of prophylactic tranexamic acid (TXA) versus a control (placebo or no treatment) during hysterectomy for benign conditions. Six databases were screened from inception to January 23, 2022. Eligible studies were assessed for risk of bias. Outcomes were summarized as weighted mean differences and risk ratios with 95% confidence intervals in a random-effects model. Five studies, comprising six arms and 911 patients were included in the study. Two and three studies had an overall unclear and low risk of bias, respectively. Estimated intraoperative blood loss, requirement for postoperative blood transfusion, and requirement for intraoperative topical hemostatic agents were significantly reduced in a prophylactic TXA group when compared with a control group. Moreover, postoperative hemoglobin level was significantly higher in the prophylactic TXA group than in the control group. Conversely, the frequency of self-limiting nausea and vomiting was significantly higher in the prophylactic TXA group than in the control group. There were no significant differences between the groups in terms of surgery duration, hospital stay, and diarrhea rate. All the RCTs reported no incidence of major adverse events in either group, such as mortality, thromboembolic events, visual disturbances, or seizures. There was no publication bias for any outcome, and leave-one-out sensitivity analyses demonstrated stability of the findings. Among patients who underwent hysterectomy for benign conditions, prophylactic TXA appeared largely safe and correlated with substantial reductions in estimated intraoperative blood loss and related morbidities.
RESUMEN
BACKGROUND AND AIM: The impact of 17ß-estradiol plus norethisterone acetate administration on serum lipids in women is controversial as previously published studies have produced conflicting results. Thus, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the effects of 17ß-estradiol plus norethisterone acetate therapy on total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) in females. METHODS: We searched the PubMed/MEDLINE, Scopus, Embase, and Web of Science databases for relevant trials published in English until 15 July 2021. The weighted mean difference (WMD) and 95% confidence intervals (CIs) were calculated using a random-effects model (the DerSimonian and Laird methods). RESULTS: A total of 32 RCTs were included in the final analysis. Treatment with 17ß-estradiol plus norethisterone acetate significantly decreased LDL-C (WMD: -13.49â¯mg/dL, 95% CI: -16.46 to -10.52; Pâ¯<â¯0.001), HDL-C (WMD: -3.57â¯mg/dL, 95% CI: -5.56 to -1.58; Pâ¯<â¯0.001), TC (WMD: -19.33â¯mg/dL, 95% CI: -24.14 to -14.52; Pâ¯<â¯0.001), and TG (WMD: -10.86â¯mg/dL, 95% CI: -16.06 to -5.13; Pâ¯<â¯0.001) levels in females. The non-linear dose-response meta-analysis revealed a negative correlation between HDL-C levels and increased treatment periods (Pâ¯Ëâ¯0.001). CONCLUSION: Evidence to date suggests that the administration of 17ß-estradiol plus norethisterone acetate in females reduces LDL-C, HDL-C, TC, and TG concentrations. Future investigations should clarify whether the reduction in HDL-C following the administration of 17ß-estradiol plus norethisterone acetate is clinically significant and poses any risks to the subjects who receive this treatment.

OBJECTIVE: To conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) that inspected the efficacy and safety of prophylactic TXA compared with control (placebo/no treatment) among women undergoing vaginal delivery on reducing postpartum blood loss and related morbidities. METHODS: Six databases were screened from inception until 06-December-2021. The pooled data were summarized as mean difference or risk ratio, respectively, with 95% confidence interval in a fixed- or random-effects model. RESULTS: Sixteen studies comprising 17 RCT treatment arms were included. There were 7122 patients; 3611 and 3511 patients were allocated to prophylactic TXA and control groups, respectively. Overall, the included RCTs had a low risk of bias. Prophylactic TXA correlated with a significant decrease in mean postpartum blood loss and mean change in hemoglobin/hematocrit. Moreover, prophylactic TXA was linked to decreased incidence rates of postpartum hemorrhage, need for blood transfusion, and need for additional uterotonic agents. Nevertheless, prophylactic TXA culminated in significantly higher incidence rates of nausea, vomiting, and diarrhea, all of which were well-tolerated. There was no increased risk of thromboembolic events. Leave-one-out sensitivity analysis confirmed the robustness of efficacy endpoints. There was no publication bias for the endpoint of mean postpartum blood loss. CONCLUSION: Among patients undergoing vaginal delivery, prophylactic TXA during active management of third stage of labor (AMTSL) appeared largely safe and correlated with a significant decrease in postpartum blood loss and related morbidities compared with control intervention. Prophylactic TXA should be integrated as a "formal" component of AMTSL among women undergoing vaginal delivery.

We aimed to perform a systematic review and meta-analysis of all randomized placebo-controlled trials (RCTs) that examined the analgesic benefits of preemptive pregabalin among patients undergoing minimally invasive hysterectomy. Five major databases were systematically screened from inception until August 29, 2021 Relevant studies were evaluated for risk of bias. Endpoints were analyzed using the random-effects model and pooled as the mean difference or risk ratio with a 95% confidence interval. Four studies with seven treatment arms met the inclusion criteria. The total sample size was 304 patients: 193 and 111 patients were allocated to the pregabalin and placebo groups, respectively. Overall, the included studies revealed a low risk of bias. The summary results revealed that the mean postoperative pain scores at rest were significantly lower in the pregabalin group than in the control group at 0, 2, 4, 6, 12, and 24 hours. Moreover, the mean postoperative pain scores on movement/coughing were significantly lower in the pregabalin group than in the control group at 12 and 24 hours. The rate of patients who were opioid-free postoperatively was significantly higher in the pregabalin group than in the control group. There was no significant difference between the groups in terms of the mean postoperative time to first rescue analgesic and the rates of adverse events. Compared with placebo, preemptive pregabalin was largely safe, and was correlated with superior analgesic effects in terms of lower postoperative pain scores and higher opioid-sparing effects. Additional RCTs are needed to confirm these findings.
RESUMEN
OBJECTIVE: Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are two increasing important problems among children. This study aims to explore the link between maternal polycystic ovary syndrome (PCOS) and the risk of ASD and ADHD in the offspring. METHOD: The MOOSE guidelines were followed in the conduct of this meta-analysis. A literature search was done in PubMed/MEDLINE, Scopus, and Web of Science from inception until January 2021. The DerSimonian and Laird random-effects model was used to estimate the combined risk ratios (RR) and 95% confidence intervals (CI). Sensitivity analysis was also used to investigate the effect of each study on the combined results. RESULTS: Seven studies, with 1,358,696 participants, comprising 7,334 ADHD cases and 3,920 ASD cases, were included in this study. Children born to mothers with maternal PCOS had higher risks of developing ASD (RR = 1.46, 95% CI: 1.26-1.69, I2 = 64%) and ADHD (RR = 1.43, 95% CI: 1.35-1.41, I2 = 0%) when compared with children born to mothers without maternal PCOS. CONCLUSION: This study showed that there might be a link between maternal PCOS and the risk of developing ASD and ADHD in the offspring. This important issue must be considered in PCOS women during and after pregnancy.

We systematically investigated the efficacy and safety of EMLA (5% lidocaine-prilocaine cream) versus placebo for pain relief among infertile patients undergoing hysterosalpingography (HSG). We screened four databases from inception until 25 November 2020. We included only randomised placebo-controlled trials (RCTs) and assessed their risk of bias. The main efficacy outcomes included safety and pain scores during the different stages of HSG. The pooled outcomes were summarised as mean difference (MD) with 95% confidence interval (CI). Three RCTs were included, comprising 258 patients (131 and 127 patients received EMLA and placebo, respectively). All RCTs revealed an overall low risk of bias. EMLA significantly reduced pain perception during cervical instrumentation of tenaculum and cannula (MD = -1.53, 95% CI [-2.59, -0.47], p = 0.005) and at 24 h after completion of HSG (MD = -1.30, 95% CI [-2.57, -0.03], p = 0.04). Despite EMLA decreased pain perception during the other procedural stages of HSG, the differences were not statistically significant compared with placebo. EMLA was safe and free of local and systemic adverse reactions. This meta-analysis advocates that topical application of 5% EMLA cream is safe and correlates with decreased pain perception during HSG, particularly during the cervical instrumentation step and at 24 h after HSG completion.
RESUMEN
PURPOSE: BRCA gene mutations (BRCAm) have an impact on patients' characteristics and clinical outcomes of ovarian cancer (OC). The frequency and patterns of BRCAm vary among countries and ethnicities. There are limited data from Saudi Arabia (SA); thus, this study aims to determine the frequency, pattern, and impact on patient characteristics and outcomes of BRCAm OC compared to wild-type BRCA (BRCAw) in Saudi women. METHODS: This retrospective study evaluated women diagnosed with non-mucinous OC, fallopian tube, or peritoneal carcinoma who had BRCA status tested in an accredited lab between January 2016 and December 2017. The associations between various parameters and BRCAm were estimated using logistic regression. Statistical analysis performed with SPSS (Version 27). RESULT: Sixty-one women with a median age of 52 at diagnosis were analyzed. Germline BRCA mutations were found in 41% of cases (25/61). The most common deleterious germline BRCA1 mutation was c.1140dupG (39%). Most women (72%) had no family history of cancers and 82% had advanced stage. Regardless of BRCA mutations, an optimal overall response rate (ORR) to first-line treatment has been achieved although most cases relapsed (84%) and the majority were platinum-sensitive relapse (85%). Higher ORR to subsequent lines and better survival were obtained in women with BRCA-mutation. CONCLUSION: The prevalence of BRCAm of OC was higher in Saudi women compared to regional and most of the international figures. The better clinical outcomes of BRCAm women agreed with the reported evidence. Further studies on BRCA mutations of OC and genetic counseling are highly recommended. TRIAL REGISTRATION: Trial approved by the Institutional Review Board of King Faisal Specialist Hospital and Research Center (RAC # 2171137) and conducted at King Faisal Specialist Hospital and Research Center, PO Box 3354, Riyadh 11,211, Saudi Arabia.

BACKGROUND AND AIM: The effect of tamoxifen administration on serum lipids in females remains unclear. The studies which have explored this topic have produced conflicting results, probably due to discrepancies in the length of the intervention, differences in baseline variables or other factors. To answer this research question, we decided to conduct this systematic review and meta-analysis to assess the effects of tamoxifen on the lipid profile in women. METHODS: A comprehensive search was conducted in Web of Science, Scopus, PubMed/Medline and Embase, from the inception of these databases up to June 2021. We used a random effects meta-analysis to generate the combined results. RESULTS: The overall findings were generated from 18 eligible trials. As compared to placebo, tamoxifen led to a notable reduction of the total cholesterol (TC) (WMD: -23.03 mg/dL, 95% CI: -25.94 to -20.12, PË0.001), and the low-density lipoprotein-cholesterol (LDL-C) (WMD: -18.68 mg/dL, 95% CI: -24.31 to -13.04, PË0.001). However, tamoxifen did not alter triglycerides (TG) concentrations (WMD: +1.06 mg/dL, 95% CI: -11.08 to 13.20, P = 0.864) significantly. A pronounced reduction of the high-density lipoprotein-cholesterol (HDLC) was noted in the RCTs with a duration of ≤52 weeks (WMD: -2.06 mg/dL) and when tamoxifen was administered in participants with a BMI ≥25 kg/m2 (WMD: -1.42 mg/dL). Notable reductions in TC (WMD: -23.57 mg/dL) and LDL-C (WMD: -19.21 mg/dL) was detected when the dose of tamoxifen was ≥20 mg/day. Moreover, a significant reduction of TC (WMD: -20.23 mg/dL) and LDL-C (WMD: -24.13 mg/dL) was observed in the RCTs with a duration of ≤52 weeks. CONCLUSION: Tamoxifen can alter the lipid profile in females, particularly by decreasing TC, LDL-C and HDLC. Tamoxifen can further reduce TC and LDL-C if the dose of administration is ≥20 mg/day, the treatment duration is ≤52 weeks and if it prescribed in subjects with dyslipidemia.

Cardiovascular disease (CVD) is the greatest cause of premature death and disability globally. Numerous therapeutic strategies have been developed to improve and prevent the adverse cardiovascular events, including nutritional approaches. This systematic review and meta-analysis summarized the evidence on orange juice consumption on CVD risk factors. Four databases were searched up to September 2020. Ten randomized controlled trials were included in the final analysis. Pooled results demonstrated a significant effect of orange juice on glucose (WMD: -2.92 mg/dl, 95% CI: -5.327, -0.530, p = 0.017), insulin (WMD: -1.229 µU/ml, 95% CI: -2.083, -0.374, p = 0.005), HOMA-IR (WMD: -0.464, 95% CI: -0.747, -0.181, p = 0.001), total cholesterol (WMD: -9.84 mg/dl, 95% CI: -15.43, -4.24, p = 0.001), LDL-C (WMD: -9.14 mg/dl, 95% CI: -15.79, -2.49, p = 0.007), and CRP (WMD: -0.467 mg/l, 95% CI: -0.815, -0.120, p = 0.008) compared to control group. However, the effect of orange juice on body composition factors and other CVD risk factors was not significant compared to control group. These lowering effects of glucose, HOMA-IR, total cholesterol, and LDL-C were robust in subgroups with orange juice consumption ≥500 ml/day. This meta-analysis suggests that orange juice may be beneficial in improving several CVD risk factors.

BACKGROUND: Inconsistencies exist with regard to the influence of omega-3 supplementation on 25-hydroxyvitamin D (25(OH)D) levels, which could be attributed to many factors, such as the duration and dose of omega-3 supplementation, and individuals' baseline 25(OH)D levels. Therefore, to address the inconsistencies, we conducted a systematic review and dose-response meta-analysis to accurately determine the effect of omega-3 supplementation on 25(OH)D levels in humans. METHODS: We performed a comprehensive literature search in Web of Science, PubMed/Medline, Scopus, and Embase databases from inception up to January 2020. We included only randomized controlled trials (RCTs). We used weighted mean difference (WMD) with 95% confidence interval (CI) to assess the influence of omega-3 supplementation on serum 25(OH)D levels using the random-effects model. RESULTS: Our pooled results of 10 RCTs demonstrated an overall significant increase in 25(OH)D levels following omega-3 intake (WMD = 3.77 ng/ml, 95% CI: 1.29, 6.25). In addition, 25(OH)D levels were significantly increased when the intervention duration lasted >8 weeks and when the baseline serum 25(OH)D level was Ë20 ng/ml. Moreover, omega-3 intake ≤1000 mg/day resulted in higher 25(OH)D levels compared to omega-3 intake >1000 mg/day. CONCLUSION: In conclusion, omega-3 supplementation increased 25(OH)D concentrations, particularly with dosages ≤1000 mg/day and intervention durations >8 weeks.

AIM: To perform a systematic review and meta-analysis of all randomized placebo-controlled trials (RCTs) that inspected the analgesic benefits of intraperitoneal lidocaine instillation among patients undergoing abdominal hysterectomy. METHODS: Five electronic databases were inspected from till August 5, 2021. The eligible RCTs were evaluated for risk of bias. The pooled endpoints were summarized as mean difference (MD) or risk ratio (RR) with 95% confidence interval (CI). RESULTS: Five RCTs met the inclusion criteria comprising 263 patients (119 and 117 patients were allocated to lidocaine and control group, respectively). The included RCTs demonstrated a low risk of bias. The postoperative pain score at rest was significantly lower in favor of the lidocaine group (MD=-1.01, 95% CI [-1.20, -0.81], p<0.001), and subgroup analysis demonstrated the same at 2, 4, 8, 12, 24, and 48 h postoperatively. Moreover, the postoperative pain score at moving was significantly lower in favor of the lidocaine group (MD=-0.67, 95% CI [-1.01, -0.33], p<0.001), and subgroup analysis demonstrated the same at 2 and 48 h postoperatively. The postoperative morphine consumption during 0-24 h was significantly lower in favor of the lidocaine group (n = 5 RCTs, MD=-7.29 mg, 95% CI [-13.22, -1.37], p = 0.02). The rate of postoperative vomiting was significantly lower in favor of the lidocaine group (n = 4 RCTs, RR=0.54, 95% CI [0.31, 0.95], p = 0.03). CONCLUSION: Among patients undergoing abdominal hysterectomy, intraperitoneal lidocaine instillation is feasible, cheap, safe, and associates with effective analgesia in terms of reduced postoperative pain score and morphine consumption.

AIM: To meta-analytically examine the frequency and prognostic impact of preoperative leukocytosis in endometrial carcinoma (EC). METHODS: Five major databases were searched till 01-February-2021. Studies that evaluated the frequency of preoperative leukocytosis or its correlation with pathological and survival outcomes in EC patients were included. Data were pooled as mean differences (MD), odds ratios (OR), or hazard ratios (HR) with 95% confidence intervals. RESULTS: Nine retrospective studies, with low risk of bias, were included. The pooled prevalence of preoperative leukocytosis was 11.2% (95% CI: 8.2-14.3). There was a significant correlation between preoperative leukocytosis and FIGO stage III-IV (OR = 2.10, 95% CI: 1.60-2.75), ≥50% myometrial invasion (OR = 1.32, 95% CI: 1.02-1.72), lymph node involvement (OR = 1.83, 95% CI: 1.29-2.59), cervical involvement (OR = 2.29, 95% CI: 1.68-3.13), adnexal involvement (OR = 2.17, 95% CI: 1.42-3.31), and tumor size (MD = 1.10 cm, 95% CI: 0.63-1.58). However, preoperative leukocytosis did not significantly correlate with tumor grade II-III, non-endometrioid histology, peritoneal cytology, and lympho-vascular space involvement (p > 0.05). Additionally, preoperative leukocytosis correlated with higher rates of death (OR = 2.85, 95% CI: 2.03-4.00), tumor recurrence (OR = 2.36, 95% CI: 1.21-4.61), and worse overall survival at univariate and multivariate analyses (HR = 2.90, 95% CI: 2.24-3.75 and HR = 2.16, 95% CI: 1.59-2.94, respectively). As for disease-free survival, preoperative leukocytosis emerged as an independent prognostic factor on univariate (HR = 1.27, 95% CI: 1.16-1.39) but not multivariate (HR = 1.08, 95% CI: 1.00-1.18) analyses. CONCLUSIONS: Preoperative leukocytosis is common and correlates with poor pathological and survival outcomes in EC patients.
