First and second-generation endometrial ablation devices: A network meta-analysis.

OBJECTIVE: First-generation and second-generation endometrial ablation (EA) techniques, along with medical treatment and invasive surgery, are considered successful lines of management for abnormal uterine bleeding (AUB). We set out to determine the efficacy of first and second-generation ablation techniques compared with medical treatment, invasive surgery and different modalities of the EA techniques themselves. DESIGN: Systematic review and network meta-analysis using a frequentist network. DATA SOURCES: We searched Medline (Ovid), PubMed, ClinicalTrials.gov, Cochrane CENTRAL, Web of Science, EBSCO and Scopus for all published studies up to 1 March 2021 using relevant keywords. ELIGIBILITY CRITERIA: We included all randomised controlled trials (RCTs) that compared premenopausal women with AUB receiving the intervention of second-generation EA techniques. DATA EXTRACTION AND SYNTHESIS: 49 high-quality RCTs with 8038 women were included. We extracted and pooled the data and then analysed to estimate the network meta-analysis models within a frequentist framework. We used the random-effects model of the netmeta package in R (V.3.6.1) and the 'Meta-Insight' website. RESULTS: Our network meta-analysis showed many varying results according to specific outcomes. The uterine balloon ablation had significantly higher amenorrhoea rates than other techniques in both short (hydrothermal ablation (risk ratio (RR)=0.51, 95% CI 0.37; 0.72), microwave ablation (RR=0.43, 95% CI 0.31; 0.59), first-generation techniques (RR=0.44, 95% CI 0.33; 0.59), endometrial laser intrauterine therapy (RR=0.18, 95% CI 0.10; 0.32) and bipolar radio frequency treatments (RR=0.22, 95% CI 0.15; 0.31)) and long-term follow-up (microwave ablation (RR=0.11, 95% CI 0.01; 0.86), bipolar radio frequency ablation (RR=0.12, 95% CI 0.02; 0.90), first generation (RR=0.12, 95% CI 0.02; 0.90) and endometrial laser intrauterine thermal therapy (RR=0.04, 95% CI 0.01; 0.36)). When calculating efficacy based only on calculated bleeding scores, the highest scores were achieved by cryoablation systems (p-score=0.98). CONCLUSION: Most second-generation EA systems were superior to first-generation systems, and statistical superiority between devices depended on which characteristic was measured (secondary amenorrhoea rate, treatment of AUB, patient satisfaction or treatment of dysmenorrhoea). Although our study was limited by a paucity of data comparing large numbers of devices, we conclude that there is no evidence at this time that any one of the examined second-generation systems is clearly superior to all others.

Maternal and neonatal outcomes of COVID-19 vaccination during pregnancy, a systematic review and meta-analysis.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is associated with increased pregnancy complications. Despite effective vaccination strategies for the general population, the evidence on the safety and efficacy of Coronavirus disease 2019 (COVID-19) vaccinations in pregnancy is limited due to a lack of well-powered studies. The present study compares the maternal, neonatal, and immunological outcomes between vaccinated pregnant and unvaccinated pregnant women using a systematic review and meta-analysis approach. We included 37 studies with a total of 141,107 pregnant women (36.8% vaccinated) spread across all outcomes. Our evidence indicates a higher rate of cesarean section in the 1898 vaccinated pregnant women compared to the 6180 women who did not receive vaccination (OR = 1.20, CI = (1.05, 1.38), P = 0.007, I2 = 45%). Regarding immunological outcomes, the risk of SARS-CoV-2 infection during pregnancy or postpartum was significantly reduced in 6820 vaccinated pregnant women compared to 17,010 unvaccinated pregnant women (OR = 0.25, CI = 0.13-0.48, P < 0.0001, I2 = 61%), as evident from qualitative assessment indicating significantly higher postpartum antibody titers compared to that observed in both unvaccinated mothers and mothers who have recently recovered from a SARS-CoV-2 infection. Our analysis represents high quality evidence showing that COVID-19 vaccination effectively raises antibody titers against SARS-CoV-2. This may confer protection against infection during pregnancy and the postpartum period. In addition to being protective against SARS-CoV-2, the vaccine was associated with decreased odds of preterm delivery. Furthermore, COVID-19 vaccination may also be associated with higher odds of cesarean section.

Meta-analysis of laparoscopic radical hysterectomy, excluding robotic assisted versus open radical hysterectomy for early stage cervical cancer.

Recent evidence has shown an increase in recurrence and a decrease in overall survival in patients treated with laparoscopic radical hysterectomy (LRH) and robotic assisted radical hysterectomy (RRH) open techniques (ORH). In addition, several high quality trials were recently published regarding the laparoscopic treatment of early stage cervical cancer. We sought out to reassess the recurrence rates, overall survival, complications and outcomes associated with laparoscopic radical hysterectomy (LRH) techniques against open techniques (ORH) when robotic assisted techniques were excluded. We searched PubMed, Medline, Cochrane CENTRAL, SCOPUS, ClinicalTrials.Gov and Web of Science for relevant clinical trials and observational studies. We included all studies that compared with early stage cervical cancer receiving LRH compared with ORH. We included randomized clinical trials, prospective cohort, and retrospective cohort trials. We included studies that included LRH and RRH as long as data was available to separate the two arms. We excluded studies that combined LRH and RRH without supplying data to differentiate. Of 1244 total studies, we used a manual three step screening process. Sixty studies ultimately met our criteria. We performed this review in accordance with PRISMA guidelines. We analyzed continuous data using mean difference (MD) and a 95% confidence interval (CI), while dichotomous data were analyzed using odds ratio (OR) and a 95% CI. Review Manager and Endnote software were utilized in the synthesis. We found that when excluding RRH, the was no significant difference regarding 5-year overall Survival (OR = 1.24 [0.94, 1.64], (P = 0.12), disease free survival (OR = 1.00 [0.80, 1.26], (P = 0.98), recurrence (OR = 1.01 [0.81, 1.25], (P = 0.95), or intraoperative complications (OR = 1.38 [0.94, 2.04], (P = 0.10). LRH was statistically better than ORH in terms of estimated blood loss (MD = - 325.55 [- 386.16, - 264.94] (P < 0.001), blood transfusion rate (OR = 0.28 [0.14, 0.55], (P = 0.002), postoperative complication rate (OR = 0.70 [0.55, 0.90], (P = 0.005), and length of hospital stay (MD = - 3.64[- 4.27, - 3.01], (P < 0.001). ORH was superior in terms of operating time (MD = 20.48 [8.62, 32.35], (P = 0.007) and number of resected lymph nodes (MD = - 2.80 [- 4.35, - 1.24], (P = 0.004). The previously seen increase recurrence and decrease in survival is not seen in LRH when robotic assisted techniques are included and all new high quality is considered. LRH is also associated with a significantly shorter hospital stay, less blood loss and lower complication rate.Prospero Prospective Registration Number: CRD42022267138.

Systematic Review and Meta-analysis of laparoscopic radical hysterectomy vs. Robotic assisted radical hysterectomy for early stage cervical cancer.

OBJECTIVE: Following compelling evidence that open techniques may be related to better survival and disease free survival rates, many gynecologic oncologists in the US have turned away from performing laparoscopic radical hysterectomy (LRH) and robotic radical hysterectomy (RRH) for the treatment of early-stage cervical cancer. While this may be warranted as a safety concern, there is little high-quality data on the head-to-head comparison of LRH and RRH and therefore little evidence to answer the question of where this decrease in patient survival is originating from. In our systematic review, we aimed to compare the complications and outcomes of LRH against those of RRH. DATA SOURCES: We searched PubMed, Cochrane CENTRAL, Medline, ClinicalTrials.Gov, SCOPUS, and Web of Science from database inception until February 1st, 2022. METHODS OF STUDY SELECTION: A total of 676 studies were identified and screened through a manual three-step process. Ultimately 33 studies were included in our final analysis. We included all studies that compared LRH and RRH and included at least one of our selected outcomes. We included retrospective cohorts, prospective cohorts, case-control, and randomized clinical trials. TABULATION, INTEGRATION, AND RESULTS: Data was independently extracted manually by multiple observers and the analysis was performed using Review Manager Software. PRISMA guidelines were followed. We analyzed homogenous data using a fixed-effects model, while a random-effects model was used for heterogeneous outcomes. We found that following RRH, women had a decreased hospital stay (MD = 0.80[0.38,1.21],(P < 0.002). We found no differences in estimated blood loss (MD = 35.24[-0.40,70.89],(P = 0.05), blood transfusion rate ((OR = 1.32[0.86,2.02],(P = 0.20), rate of post-operative complications (OR = 0.84[0.60,1.17],(P = 0.30), the operative time (MD = 6.01[-4.64,16.66],(P = 0.27), number of resected lymph node (MD = -1.22[-3.28,0.84],(P = 0.25) intraoperative complications (OR = 0.78[0.51,1.19],(P = 0.25), five-year overall survival (OR = 1.37[0.51,3.69],(P = 0.53), lifetime disease free survival (OR = 0.89[0.59,1.32],(P = 0.55), intraoperative and postoperative mortality (within 30 days) (OR = 1.30[0.66,2.54],(P = 0.44), and recurrence (OR = 1.14[0.79,1.64],(P = 0.50). CONCLUSIONS: RRH seems to result in the patient leaving the hospital sooner after surgery. We were unable to find any differences in our ten other outcomes related to complications or efficacy. These findings suggest that the decreased survival seen in minimally invasive RH in previous studies could be due to factors inherent to both LRH and RRH.

Prognostic value of left atrial expansion index and exercise-induced change in atrial natriuretic peptide as long-term predictors of atrial fibrillation recurrence.

AIMS: We propose to assess the value of exercise-induced change in N-terminal-pro atrial natriuretic peptide (NT-proANP) and left atrial expansion index (LAEI) in predicting AFR after cardioversion and their effect on AF-free survival. METHODS AND RESULTS: Fifty-five patients with persistent AF of <18 months duration needing cardioversion were recruited for the study. Fifty-four patients were successfully cardioverted. At 3 months 28/54 (51%) were in SR and at 12 months 21/53 (39%). On multivariate analysis, only exercise-induced change in NT-proANP and LAEI were found to be predictive of AFR up to 12 months post-cardioversion and had an effect on AF-free survival. N-terminal-pro brain natriuretic peptide was elevated in all persistent AF patients but did not predict recurrent AF. CONCLUSIONS: Left atrial expansion index and exercise-induced atrial natriuretic peptide change show promise as predictors of AFR after cardioversion. These predictors may identify patients at an early stage in their disease with intact neurohumoral feedback systems and less advanced atrial remodelling. Further studies are required to confirm these findings.

Specificity of elevated intercostal space ECG recording for the type 1 Brugada ECG pattern.

BACKGROUND: Right precordial (V1-3) elevated electrode placement ECG (EEP-ECG) is often used in the diagnosis of Brugada syndrome (BrS). However, the specificity of this has only been studied in smaller studies in Asian populations. We aimed to study this in a larger European population. METHODS: Two different populations consisting of healthy subjects were used. A total of 340 subjects were included, 80% were men, the median age was 43 year (interquartile range: 31-51) and all were of European ethnicity. RESULTS: No type 1 ECG patterns were identified but 16 (4.7%) subjects with a type 2 ECG and 32 (9.4%) subjects with a type 3 ECG were identified in any lead placement. In total 43 (13%) subjects had any BrS ECG pattern in any lead placement. The specificity was 100% (one-sided 97.5% CI: 99%) for the use of EEP-ECG to uncover type 1 pattern. For type 2 pattern the specificity was 95% (95% CI: 92-97%) and for type 3 pattern 91% (95% CI: 88-94%). CONCLUSIONS: Elevated electrode placement ECG in the diagnosis of BrS seems to have a very high specificity with regards to the finding of a type 1 ECG pattern in a European population; conversely a finding of a type 2 or 3 pattern is of a significantly lower specificity and should perhaps be disregarded.

Treatment of Cesarean Scar Ectopic Pregnancy in China with Uterine Artery Embolization-A Systematic Review and Meta-Analysis.

Cesarean scar ectopic pregnancy (CSP) is a rare form of ectopic pregnancy, and treatment of CSP with uterine artery embolization (UAE) is a novel approach. With increasing numbers of cesarean sections being performed annually, the incidence of this condition is likely to increase. The authors became aware of an unusually high number of published studies originating in mainland China regarding this unusual treatment and sought to perform a meta-analysis to provide comprehensive evidence on this novel practice. METHODS: We performed a thorough search and included all forms of quality studies on this topic that reported UAE as a part of first-line management of CSP. We included only studies originating in China. Ultimately, 37 studies were included for qualitative and quantitative synthesis of evidence. After screening retrieved records and extracting data from eligible studies, we pooled continuous data as a mean estimate and 95% confidence interval (CI), and dichotomous data as proportion and 95% CI. RESULTS: CSP patients treated with protocols including UAE had a mean time of 30 days for serum ß-hCG normalization, 95% CI [26.816, 33.881]. They had a mean estimated intraprocedural blood loss of 4.19 ± 3.76 mL, a mean hospital stay of nine days, 95%CI [7.914, 9.876], and a success rate of 93.4%, 95%CI [0.918, 0.951]. The severe complication rate was 1.2%, 95%CI [0.008, 0.017]. CONCLUSION: UAE, in combination with other procedures is being used effectively for the treatment of CSP in China. Protocols including UAE have a success rate of approximately 93.4%, and a severe complication rate of approximately 1.2%. This data's utility is limited by vast differences in the studied protocols and questionable feasibility outside of China.

Systematic review and meta-analysis of Veress needle entry versus direct trocar entry in gynecologic surgery.

Objective: Although many studies have been performed, no consensus exists as to the ideal entry for laparoscopic gynecologic surgery. We sought out to compare the safety of direct trocar insertion with that of the Veress needle entry technique in gynecologic laparoscopic surgery. Design: Systematic review with meta-analysis. Setting: We searched Medline, ClinicalTrials.Gov, PubMed, Cochrane CENTRAL, SCOPUS, and Web of Science from their inception through 31 July 2021 for relevant studies. We included only controlled trials and ultimately seven trials were included in our meta-analysis. Participants: Inclusion criteria included women undergoing gynecological laparoscopic surgery. Intervention: The intervention of direct trocar insertion technique compared with Veress needle entry technique. Main outcome measures: We compared five different outcomes associated with the efficacy and complications of laparoscopic entry. Results: The pooled analysis showed that Veress needle entry was associated with a significant increase in the incidences of extraperitoneal insufflation (RR=0.177, 95% Cl (0.094 to 0.333), p<0.001), omental injury (RR=0.418, 95% Cl (0.195 to 0.896), p<0.001), failed entry (RR=0.173, 95% Cl (0.102 to 0.292), p<0.001), and trocar site infection (RR=0.404, 95% Cl (0.180 to 0.909), p<0.029). There was no significant difference between the two groups regarding the visceral injury (RR=0.562, 95% Cl (0.047 to 6.676), p<0.648). Conclusions: When excluding all data apart from gynecologic surgery, the Veress needle entry technique may have an increased incidence of some, but not all complications of laparoscopic entry. It may also have a higher incidence of failed entry compared with direct entry techniques. Care should be taken in extrapolating these general results to specific surgeon experience levels.

Efficacy of laparoscopic and trans-abdominal cerclage (TAC) in patients with cervical insufficiency: A systematic review and meta-analysis.

BACKGROUND: Cervical insufficiency (CI) may result in preterm delivery. We sought out to perform this review and analysis to compare the efficacy of laparoscopic and open transabdominal cerclage (TAC) in patients suffering with CI. METHODS: Our search included PubMed, Scopus, MEDLINE, ClinicalTrials.Gov, Cochrane and Web of Science. We analyzed the data with Open Meta-Analyst Software as well as Review Manager Software. We included observational and randomized controlled trials that included patients with CI that underwent laparoscopic cerclage or TAC. RESULTS: We included a total of 43 studies. Laparoscopic and TAC had a positive effect by increasing gestational age (GA); for the laparoscopic group (mean deviation (MD)) = 14.86 weeks (W), 95% CI [10.67, 19.05], P < 0.001) and TAC (MD = 12.79 W, 95% CI [10.97, 14.61], P < 0.001). Furthermore, improvements in all outcomes assessed (total fetal survival rate, neonatal weight, and prevention of delivery at a gestational age of<24 weeks) were all significant with the exception of the prevention of all preterm deliveries<37 weeks; for both laparoscopic at (RR = 0.116, 95% CI [-0.006, 0.238], P = 0.063) and TAC at (MD = 1, 95% CI [0.45, 2.24], P = 1), and for prevention of deliveries<34 weeks for the laparoscopic group (RR = 0.446, 95% CI [-0.323, 1.215], P = 0.256) only. CONCLUSIONS: Although limited data prevented pregnancy and prepregnancy subgroups as well as a head-to-head comparison, we still found that in patients suffering from CI, both TAC and laparoscopic approaches to cerclage revealed a positive effect in preserving the pregnancy.

Systematic review and meta-analysis of the efficacy of gabapentin in chronic female pelvic pain without another diagnosis.

Background: While widely used for the treatment of chronic pelvic pain, limited data exists on efficacy of gabapentin, especially in the subgroup of women suffering from chronic pelvic pain without a known diagnosis, such as endometriosis. Objective: This study aimed to assess the efficacy of gabapentin when administered to women with chronic pelvic pain without another diagnosis. Study Design: We performed a Systematic Review and Meta Analysis including all controlled clinical trials addressing the use of gabapentin for the treatment of chronic pelvic pain without another diagnosis. We searched PubMed, Scopus, Web of Science, ClinicalTrials.Gov, MEDLINE, and The Cochrane Library from inception of each database to April 30, 2021. We included all the studies that fulfilled the following criteria: (1) population: women suffering from chronic pelvic pain without another identified diagnosis (such as endometriosis); (2) intervention: gabapentin (regardless of the dosage); (3) comparator:placebo; (4) outcomes: pain score (visual analog scale) after 3 months and pain score (visual analog scale) after 6 months as primary outcomes; and (5) study design: we only included randomized or controlled clinical trials. Our exclusion criteria included (1) uncontrolled clinical trials, (2) studies that did not report data or measures for any of our selected outcomes, (3) studies that included patients with surgically or clinically diagnosed endometriosis, or (4) studies with no full-text manuscript available. Risk of bias assessment was performed using the Cochrane risk of bias tool. We analyzed dichotomous outcomes as percentages and totals, whereas continuous outcomes were analyzed using mean difference, standard deviations, and relative 95% confidence intervals using the inverse variance method. Results: We included 4 placebo-controlled randomized controlled trials. Analysis was hindered because half of the studies (n=2) used the visual analog scale pain score and the other half (n=2) used the numerical rating scale. The analysis showed that when compared with the placebo, gabapentin significantly lowered the visual analog scale pain score at 3 months (mean difference, 0.79; 1.23 to 0.35; P=.005) and 6 months (mean difference, 1.68; 2.30 to 1.05; P=.001) and the numerical rating scale pain score at 3 months (mean difference, 0.20; 0.25 to 0.15; P=.001). However, in terms of the numerical rating scale pain score after 6 months, the 2 groups showed no significant difference (mean difference, 0.27; 0.80 to 0.26; P=.32). CONCLUSION: Gabapentin may hold benefit for the management of chronic pelvic pain, with significant improvement in pain seen in both scales at 3 months when compared with the placebo, but only in the visual analog scale group at 6 months of usage. Secondary to the differences in the nature of the 2 scales, a further weighted combined analysis was not possible.

Birth Outcomes of Neonates Exposed to Marijuana in Utero: A Systematic Review and Meta-analysis.

Importance: While some studies have found an association between marijuana use and adverse neonatal outcomes, results have not been consistent across all trials. Objective: To assess available data on neonatal outcomes in marijuana-exposed pregnancies. Data Sources: PubMed, Medline, ClinicalTrials.gov, Cochrane, Scopus, and Web of Science were searched from each database's inception until August 16, 2021. Study Selection: All interventional and observational studies that included pregnant women who were exposed to marijuana compared with pregnant women who were not exposed to marijuana and that reported neonatal outcomes were included. Data Extraction and Synthesis: Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline. Data were extracted by 2 authors for all outcomes, which were pooled using a random-effects model as mean difference or risk ratio (RR) and 95% CI. Data were analyzed from August through September 2021. Main Outcomes and Measures: All outcomes were formulated prior to data collection. Outcomes included incidence of birth weight less than 2500 g, small for gestational age (defined as less than the fifth percentile fetal weight for gestational age), rate of preterm delivery (defined as before 37 weeks' gestation), gestational age at time of delivery, birth weight, incidence of neonatal intensive care unit (NICU) admission, Apgar score at 1 minute, Apgar score at 5 minutes, incidence of an Apgar score less than 7 at 5 minutes, fetal head circumference, and fetal length. Results: Among 16 studies including 59 138 patients, there were significant increases in 7 adverse neonatal outcomes among women who were exposed to marijuana during pregnancy vs those who were not exposed during pregnancy. These included increased risk of birth weight less than 2500 g (RR, 2.06 [95% CI, 1.25 to 3.42]; P = .005), small for gestational age (RR, 1.61 [95% CI, 1.44 to 1.79]; P < .001), preterm delivery (RR, 1.28 [95% CI, 1.16 to 1.42]; P < .001), and NICU admission (RR, 1.38 [95% CI, 1.18 to 1.62]; P < .001), along with decreased mean birth weight (mean difference, -112.30 [95% CI, -167.19 to -57.41] g; P < .001), Apgar score at 1 minute (mean difference, -0.26 [95% CI, -0.43 to -0.09]; P = .002), and infant head circumference (mean difference, -0.34 [95% CI, -0.63 to -0.06] cm; P = .02). Conclusions and Relevance: This study found that women exposed to marijuana in pregnancy were at a significantly increased risk of some adverse neonatal outcomes. These findings suggest that increasing awareness about these risks may be associated with improved outcomes.

Salpingectomy, tubal ligation and hysteroscopic occlusion for sterilization.

INTRODUCTION: Sterilization of females is considered one of the most prevalent contraceptive techniques among women in the United States. There are many surgical sterilization procedures including salpingectomy, tubal ligation, and hysteroscopic occlusion of the fallopian tubes. We provide an overview of these methods from the clinical data and latest studies available on this topic. EVIDENCE ACQUISITION: In order to review the latest literature on the topic, we searched electronic databases including PubMed, Web of Science, Scopus, and Cochrane library for all eligible studies from May 1st 2018 until May 1st 2022 using the following strategy: ("fallopian tube removal" OR Salpingectomy OR "fallopian tube excision" OR "tubal sterilization") AND ("tubal ligation" OR "bipolar coagulation" OR "tubal clip" OR "tubal ring" OR fimbriectomy). We reviewed every study that met our criteria and subjectively considered their results and methodology into this narrative review. EVIDENCE SYNTHESIS: In addition to reviewing major guidelines in the United States, 19 recent studies met our eligibility criteria and were included in this review. We grouped the findings under the following headings: anatomical and physiological considerations, sterilization, salpingectomy, tubal ligation, and hysteroscopic tubal occlusion. CONCLUSIONS: Bilateral salpingectomy and techniques of tubal ligation or occlusion continue to be effective procedures with good safety profiles. All techniques have similar surgical outcomes and long-term success rates. As salpingectomy has the advantage of reducing the risk of occurrence of ovarian cancer, this is preferential when feasible. Hysteroscopic occlusion techniques may be more minimally invasive but have the disadvantages of delayed efficacy, the need for a second invasive diagnostic procedure, and limited availability.

Assessment of aortic stiffness in marfan syndrome using two-dimensional and Doppler echocardiography.

BACKGROUND: Extracellular matrix remodeling in the aortic wall results in increased aortic stiffness (AoS) in Marfan syndrome (MFS). Pulsed-wave velocity (PWV) constitutes the best indirect AoS measurement. We aimed to assess PWV in MFS patients using two-dimensional (2D) and Doppler echocardiography. METHODS: Thirty-one MFS patients, (mean age 31 ± 14 years, 16 men) and 31 controls were examined. Blood flow was recorded in the aorta near the aortic valve and immediately after in the descending aorta with simultaneous electrocardiography. PWV was calculated by dividing the distance between the two sample volume positions (D) by the time difference (TD) between the intervals from the QRS start to the ascending and descending aortic flow onsets. B-stiffness was also measured. RESULTS: TD (described in "Methods" section) and, aortic arch length were significantly increased in MFS patients, P < 0.001. Thus, PWV values were significantly higher in patients when compared with controls, 7.20 m/s (5.12, 9.43) versus 4.64 m/s (3.37, 6.24), P < 0.001. B-stiffness was also significantly increased in MFS patients; 5.15 (3.69, 7.65) versus 2.44 (1.82, 3.66), P < 0.001. Multiple regression analysis showed a positive association with MFS diagnosis and age, (P = 0.002 and 0.009, respectively). Reproducibility of PWV measurements was <5%. CONCLUSIONS: AoS was significantly higher in MFS patients as expected. Our data demonstrated that PWV measurements can be performed, in the absence of serious musculoskeletal abnormalities in MFS adults, as part of a cardiac ultrasound scan. This technique can be helpful in diagnosis and management in MFS.

Impaired biventricular deformation in Marfan syndrome: a strain and strain rate study in adult unoperated patients.

OBJECTIVE: To investigate the presence of any regional myocardial deformation abnormalities in Marfan syndrome (MFS) and determine the benefits of using advanced echocardiography compared to conventional techniques. BACKGROUND: Myocardial dysfunction in MFS may be caused by extracellular matrix remodeling thus, resulting in uniform reduced functionality. However, increased aortic stiffness may cause segmental ventricular abnormalities. Strain rate imaging (SRI) constitutes a validated technique to assess regional deformation in various clinical conditions. With this in mind, we aimed to investigate biventricular function in MFS using SRI. METHODS: Forty-four MFS patients (mean age 30 ± 12 years, 26 men) and 49 controls without valvular disease were examined using SRI. Ejection fraction (EF) was calculated by the Simpson's biplane method. Biventricular deformation was assessed by measuring strain/strain rate. Strain values were divided by left ventricular (LV) end-diastolic volume to adjust LV deformation for geometry changes providing a strain index (SI). Aortic stiffness was evaluated using the ß-stiffness index. RESULTS: EF (%) was reduced in MFS patients (59 ± 5 vs 72 ± 4, P < 0.001), whereas ß-stiffness was increased (P < 0.001). LV radial and LV and right ventricular (RV) long-axis strain values (%) were reduced in the patient group (70 ± 17 vs 93 ± 10; 19 ± 2 vs 25 ± 2; 30 ± 9 vs 36 ± 8, respectively, P < 0.001). Strain rate measurements were also reduced (P < 0.001). In a multiple regression analysis, MFS diagnosis was negatively associated with LV SI (-0.262 [-0.306, -0.219], P < 0.001). ß-Stiffness was negatively associated with SI obtained from the septum, inferior and anterior walls. ROC analyses demonstrated that SRI, when compared with conventional echocardiography, had higher sensitivity and specificity in predicting biventricular dysfunction in MFS. CONCLUSIONS: Our study showed a uniform reduction in biventricular deformation in MFS. These findings suggest that assessment of myocardial function using advanced echocardiographic techniques could be more accurate in MFS patient evaluation than conventional echocardiography alone.

Complications and objective outcomes of uterine preserving surgeries for the repair of pelvic organ prolapse versus procedures removing the Uterus, a systematic review.

BACKGROUND: Several authors have recently compared the outcomes and complications of surgical procedures that preserve or remove the uterus in the treatment of pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Following the publication of several high quality randomized control trials on this topic we performed a new systematic review and meta analysis of this data. METHODS: We performed a systematic literature search in ClinicalTrials.gov, PubMed, Scopus, Ovid, EBSCO host, Science Direct, Web of Science, and Cochrane CENTRAL for randomized controlled and cohort trials of uterine sparing prolapse repair (hysteropexy) versus hysterectomy with suspension. A total of 1285 patients from 14 studies were included in our systematic review and meta-analysis. RESULTS: Uterine sparing procedures (hysteropexy) were comparable to hysterectomy with suspension for recurrence rates (RR = 0.908, 95% CI [0.385, 2.143]), reoperation rates (RR = 1.517, 95% CI [0.802, 2.868]), length of hospital stay, (SMD =  - 0.159 days, 95% CI [-0.375, 0.057]), voiding dysfunction (RR = 1.089, 95% CI [0.695, 1.706]), and intraoperative blood loss (SMD =  - 0.339, 95% CI [-0.631, 0.047]). However, hysteropexy had shorter operative time than hysterectomy with suspension (SMD =  - 1.191 h, 95% CI [-1.836, -0.545]), and fewer visceral injuries (RR = 0.421, 95% CI [0.244, 0.725]). CONCLUSION: We found no significant differences in the outcomes or major complications of uterine preserving surgical procedures versus those which include hysterectomy in the treatment of POP. Hysteropexy procedures may be associated with a shorter operative time and fewer visceral injuries. This is consistent with older analyses.

Systematic review and meta-analysis of all randomized controlled trials comparing gynecologic laparoscopic procedures with and without robotic assistance.

OBJECTIVE: Following the publication of several high quality randomized controlled trials regarding the comparison of similar laparoscopic gynecologic procedures being performed with or without robotic assistance, we aimed to perform a systematic review to identify any differences in patient safety and expected incidence of complications in these procedures. DATA SOURCES: Articles on ClinicalTrials.Gov, Embase, MEDLINE, PubMed, Scopus, and Web of Science databases were retrieved and screened for eligibility up to April 1st 2021. METHODS OF STUDY SELECTION: In addition to meeting our screening algorithm, we included studies that met all the following: randomized control trials (RCT), enrolling patients for indicated laparoscopic gynecologic procedures, and comparing Robotic Surgery (RS) with Laparoscopic Surgery (LS) in terms of safety or complications. TABULATION, INTEGRATION, AND RESULTS: Data was pooled as mean difference (MD) or risk ratio (RR) with a 95% confidence interval (CI). Ultimately, six studies were included in this meta-analysis. Pooled data revealed that RS and LS have similar risk for intraoperative complications (RR = 0.87; 95% CI [0.23, 3.36], P = 0.84), postoperative complications (RR = 1.07; 95% CI [0.57, 2.01], P = 0.83), significant intraoperative hemorrhage (RR = 1.40; 95% CI [0.59, 3.34], P = 0.44), postoperative hemorrhage (RR = 0.43; 95% CI [0.15, 1.22], P = 0.11), vaginal cuff dehiscence (RR = 1.13; 95% CI [0.24, 5.41], P = 0.88), postoperative wound infection, urinary tract infection, and urinary bladder or ureteral injury. RS had "surgeon declared" lower estimated blood loss (MD = 85.27; 95% CI [46.45, 124.09], P < 0.00001) and shorter postoperative hospital stay (MD = 1.20; 95% CI [0.38, 2.01], P = 0.004). CONCLUSION: There was a statistically significant decrease in hospital stay and "surgeon declared" blood loss seen in the RS group. There was no statistically significant increase in risk of developing other postoperative complications between the LS and R groups.

A Systematic Review and Meta-Analysis of Intraperitoneal Bupivacaine in Laparoscopic Gynecologic Surgery.

OBJECTIVE: We set out to evaluate whether the instillation of bupivacaine versus a saline solution into the peritoneal cavity at time of laparoscopic gynecologic surgery will reduce postoperative pain and postoperative opioid consumption. DATA SOURCES: We searched six databases: Web of Science, SCOPUS, Cochrane CENTRAL, ClinicalTrials.Gov, MEDLINE and PubMed. Our search strategy had no restriction on time or languages and included all studies that met our search algorithm up to March of 2021. METHODS OF STUDY SELECTION: We included only randomized trials that met our search strategy for the outcomes of 1) pain intensity 24 hours after surgery, 2) pain intensity 6 hours after surgery, and 3) length of hospital stay. TABULATION INTEGRATION AND RESULTS: We analyzed continuous data using mean difference (MD) with relative 95% confidence interval (CI). We included 8 randomized clinical trials. We found that intraperitoneal bupivacaine showed significant difference from the saline group regarding pain intensity 24 hours after surgery (MD= -0.73 [-1.10, -0.36]) (P = 0.01) and pain intensity 6 hours after surgery (MD= -1.12 [-2.22, -0.02]) (P = 0.05). Overall, patients allocated to the placebo group seemed to need other analgesics earlier than patients allocated to the bupivacaine group (MD=145.08 [51.37, 238.79] (P = 0.02)). There was no significant difference regarding the length of hospital stay (MD= -0.44 [-1.44, 0.56]) (P = 0.39). CONCLUSION: Bupivacaine significantly reduced the visual analog pain score for pain compared with that of the placebo at 6 and 24 hours postoperatively. There was no significant difference in hospital stay. PROSPERO REGISTRATION: CRD42021254268.

A rare connection: fasciculoventricular pathway in PRKAG2 disease.

Mutations in the PRKAG2 gene that regulates the gamma 2 subunit of the AMP-dependent protein kinase A have been associated with the development of AV accessory pathways, cardiac hypertrophy, and conduction system abnormalities. The accessory pathways described in PRKAG2 disease have mostly been AV bypass tracts, as mutations in the PRKAG2 gene disrupt the normal AV junction development. There have also been a few reports of nodoventricular tracts associated with PRKAG2 mutations, as these tracts also involve the AV junction. We describe a case of a fasciculoventricular pathway with PRKAG2 mutation suggesting a more widespread involvement of the PRKAG2 gene in the development of the cardiac conduction system.

Brugada-like changes in the peripheral leads during diagnostic ajmaline test in patients with suspected Brugada syndrome.

BACKGROUND: Although cases of Brugada-type electrocardiographic (ECG) pattern in peripheral (limb) leads have been reported ("atypical" Brugada syndrome [BS]), their incidence in patients investigated for BS is unknown. METHODS: We retrospectively analyzed an ECG database collected during ajmaline test in 143 patients (89 men) with suspected BS. In 42 patients, 12-lead ECGs were recorded, whereas in 101 patients, leads V1-V3 from the third intercostal space were also recorded. The presence of types 1, 2, and 3 Brugada pattern in each limb and precordial lead was noted and the PR, QRS, and QTc intervals were calculated. RESULTS: There were 114 (79.7%) negative and 29 (20.3%) positive tests. Type 1 pattern developed in >or=1 limb lead in six patients (4.2%) (3/29 with positive tests, 10.3%); all of them were male, symptomatic, and/or with family history of BS or sudden cardiac death. Their pre- and posttest QRS were significantly longer compared with the rest with positive (n = 26) or negative (n = 111) test (pretest: 129 +/- 31 ms vs 101 +/- 11 ms and 97 +/- 12 ms, P < 0.001; posttest: 175 +/- 44 ms vs 134 +/- 14 ms and 131 +/- 19 ms, P < 0.001). The posttest QTc was longer in patients with peripheral changes compared with the rest (507 +/- 47 ms vs 453 +/- 22 ms and 447 +/- 24 ms, P < 0.001). The pretest QTc and pre- and posttest heart rate and PR intervals were not significantly different between the three groups. CONCLUSIONS: Type 1 Brugada pattern in the peripheral leads was observed in 4.2% of patients during ajmaline test (10.3% of positive tests) and was associated with longer QRS and greater QTc prolongation compared with the rest of the patients.

The place of hybrid therapies with drugs to supplement nonpharmacological therapies in atrial fibrillation.

Atrial fibrillation (AF) is one of the most common cardiac arrhythmias, and its prevalence continues to rise as the aged population increases. Comparative studies of rhythm control and rate control have been equivocal; however, the benefits of rhythm control may have been offset by the limitations of antiarrhythmic drugs. More recently, nonpharmacological therapies have emerged that provide hope of more effective rhythm control. Catheter ablation techniques have gained favour with high success rates in specialized centers, although these techniques are not without complications and require considerable expertise. Pacing therapies designed to reduce harmful right ventricular pacing and increase physiological pacing have shown benefit in AF patients with bradycardia. Despite this progress, no single modality confers benefit for all patients. Strategies to combine these treatment modalities in a hybrid approach has shown increasing promise for subgroups of AF patients.
