Comparative Study Review
OBJECTIVES
A variety of operative techniques have been described as under the term 'Bristow-Latarjet' procedure. This review aims to define the original procedure, and compare the variation in techniques described in the literature, assessing any effect on clinical outcomes.
MATERIALS AND METHODS
A systematic review of 24 studies was performed to compare specific steps of the technique (coracoid osteotomy site, subscapularis approach, orientation and position of coracoid graft fixation and fixation method, additional labral and capsular repair) and detect any effect this variability had on outcomes.
RESULTS
Overall recurrence rate was 5.36% (2.94% to 43%). Half of the studies performed the procedure for recurrent shoulder instability, with only five studies documenting glenoid bone loss as an indication: 12 studies used the procedure as the primary surgical intervention for recurrent instability. No change in outcome was noted when examining variation in the coracoid osteotomy site, the fixation site on the scapular neck, the fixation method or whether a capsular repair was also performed. Performing a horizontal split in subscapularis may preserve external rotation compared with performing a tenotomy.
CONCLUSIONS
This is the first review to examine various operative techniques of the Bristow-Latarjet procedure, and their effect on outcome. We found that other than the approach through subscapularis, outcome was independent of the surgical technique, and depended more on patient selection. We would commend future publications on this procedure to provide a detailed description of the surgical technique, and as a minimum present rates of recurrence as an outcome measure.

PURPOSE OF REVIEW
Since its first description in 2003, the endometrial scratching procedure has been the topic of over 1000 studies. This procedure, used to improve endometrial receptivity for assisted reproduction, is accessible - any gynecologist can easily perform it - and has been adapted into clinical routine by some reproductive units. However, the available data are controversial, and no biological plausibility exists to support the use of this intervention. This study aims to critically review the existing data, focusing on the last 2 years, regarding the efficiency of endometrial scratching.
RECENT FINDINGS
A total of five randomized controlled studies, one meta-analysis, and a systematic review related to endometrial scratching/injury were published in 2014 and 2015. Considerable heterogeneity exists among these studies regarding the selected population, type of treatment, and even timing and devices used to perform the endometrial injury. Importantly, none of these studies reported improved reproductive outcomes in terms of live birth rates following endometrial scratching.
SUMMARY
Overall, data from properly designed and powered randomized controlled studies demonstrate no beneficial effect of this intervention that is based on unknown biological effects. Endometrial scratching produces pain, costs money, and the side-effects of systematic scratching in the production of Asherman syndrome remain to be seen. Think before scratching.

Meta-Analysis
BACKGROUND
Unintended pregnancy is popular all over the world, accounting for 40% to 50% of all pregnancies. The condition not only exerts pressure on the relationship of couples and severely impacts the quality of life, but also imposes a heavy burden on the health of women and child. Recently, more than 220 million couples have chosen to be sterilized to obtain contraception, 47.3% of married couples select sterilization, of which vasectomy accounts for 17.1%. Vasectomy is currently the most convenient and effective method of male contraception. We will perform the systematic review and meta-analysis to assess the correlation between vasectomy and male sex dysfunction and provide evidence-based evidence for the couple METHODS:: The electronic databases of MEDLINE, PubMed, Web of Science, EMBASE, Clinicaltrials.org., China National Knowledge Infrastructure Database (CNKI), Wan fang Database, China Biology Medicine Database (CBM), VIP Science Technology Periodical Database, Chinese Clinical Trial Registry, and Cochrane Library will be retrieved before November 20, 2021. We will search English literature and Chinese literature with proper Medical Subject Heading or text key words. RevMan 5.3 and Stata 14.0 will be used for Systematic review and Meta-analysis. This protocol reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement, and we will report the systematic review by following the PRISMA statement.
CONCLUSION AND DISSEMINATION
The aim of this study was to evaluate the effect of vasectomy on the sexual function of patients after operation. The results will be published in a public issue journal to provide evidence-based medical evidence for urologists and andrologists to make clinical decisions.

UNLABELLED
As more new drugs are discovered, traditional designs come at their limits. Ten years after the adoption of the European Paediatric Regulation, we performed a systematic review on the US National Library of Medicine and Excerpta Medica database of sequential trials involving newborns. Out of 326 identified scientific reports, 21 trials were included. They enrolled 2832 patients, of whom 2099 were analyzed: the median number of neonates included per trial was 48 (IQR 22-87), median gestational age was 28.7 (IQR 27.9-30.9) weeks. Eighteen trials used sequential techniques to determine sample size, while 3 used continual reassessment methods for dose-finding. In 16 studies reporting sufficient data, the sequential design allowed to non-significantly reduce the number of enrolled neonates by a median of 24 (31%) patients (IQR - 4.75 to 136.5, p = 0.0674) with respect to a traditional trial. When the number of neonates finally included in the analysis was considered, the difference became significant: 35 (57%) patients (IQR 10 to 136.5, p = 0.0033).
CONCLUSION
Sequential trial designs have not been frequently used in Neonatology. They might potentially be able to reduce the number of patients in drug trials, although this is not always the case. What is known: • In evaluating rare diseases in fragile populations, traditional designs come at their limits. About 20% of pediatric trials are discontinued, mainly because of recruitment problems. What is new: • Sequential trials involving newborns were infrequently used and only a few (n = 21) are available for analysis. • The sequential design allowed to non-significantly reduce the number of enrolled neonates by a median of 24 (31%) patients (IQR - 4.75 to 136.5, p = 0.0674).

Review
With the advancement of spatial analysis approaches, methodological research addressing the technical and statistical issues related to joint spatial and spatiotemporal models has increased. Despite the benefits of spatial modelling of several interrelated outcomes simultaneously, there has been no published systematic review on this topic, specifically when such models would be useful. This systematic review therefore aimed at reviewing health research published using joint spatial and spatiotemporal models. A systematic search of published studies that applied joint spatial and spatiotemporal models was performed using six electronic databases without geographic restriction. A search with the developed search terms yielded 4077 studies, from which 43 studies were included for the systematic review, including 15 studies focused on infectious diseases and 11 on cancer. Most of the studies (81.40%) were performed based on the Bayesian framework. Different joint spatial and spatiotemporal models were applied based on the nature of the data, population size, the incidence of outcomes, and assumptions. This review found that when the outcome is rare or the population is small, joint spatial and spatiotemporal models provide better performance by borrowing strength from related health outcomes which have a higher prevalence. A framework for the design, analysis, and reporting of such studies is also needed.

Meta-Analysis Review
OBJECTIVES
Nonvariceal gastrointestinal bleeding (NVGIB) is a common medical condition with significant mortality and morbidity. Several types of hemostatic modalities are currently available in clinical setting. This systematic review and network meta-analysis aimed to assess the efficacy of these modalities in treating NVGIB.
METHODS
PubMed, EMBASE, and the Cochrane Library databases were searched for studies that compared the efficacy of different hemostatic techniques (over-the-scope clip [OTSC], hemostatic powder [HP] and conventional endoscopic treatment [CET]) for NVGIB published up to June 2022. The 30-day rebleeding rate was regarded as the primary outcome. We performed pairwise and network meta-analyses for all treatments. The heterogeneity and transitivity were evaluated.
RESULTS
Twenty-two studies were included. Regarding the 30-day rebleeding rate, OTSC and HP plus CET showed superior efficacy in treating NVGIB compared with CET (OTSC vs CET: relative risk [RR] 0.42, 95% confidence interval [CI] 0.28-0.60; HP plus CET vs CET: RR 0.40, 95% CI 0.17-0.87), while OTSC and HP plus CET had comparable efficacy (RR 0.95, 95% CI 0.38-2.31). HP plus CET ranked the highest in the network ranking estimate. The sensitivity analysis showed that it was not robust that OTSC was superior to CET regarding the short-term rebleeding rate and the initial hemostasis rate. While all-cause mortality, bleeding-related mortality and necessity of surgical or angiographic salvage therapy showed no statistically significant difference.
CONCLUSION
OTSC and HP plus CET significantly reduced 30-day rebleeding rate compared to CET and had comparable efficacy in the treatment of NVGIB.

Meta-Analysis Review
Pharmacological agents for procedural sedation and analgesia in the emergency department and intensive care unit: a systematic review and network meta-analysis of randomised trials.
BACKGROUND
We aimed to evaluate the comparative effectiveness and safety of various i.v. pharmacologic agents used for procedural sedation and analgesia (PSA) in the emergency department (ED) and ICU. We performed a systematic review and network meta-analysis to enable direct and indirect comparisons between available medications.
METHODS
We searched Medline, EMBASE, Cochrane, and PubMed from inception to 2 March 2023 for RCTs comparing two or more procedural sedation and analgesia medications in all patients (adults and children >30 days of age) requiring emergent procedures in the ED or ICU. We focused on the outcomes of sedation recovery time, patient satisfaction, and adverse events (AEs). We performed frequentist random-effects model network meta-analysis and used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to rate certainty in estimates.
RESULTS
We included 82 RCTs (8105 patients, 78 conducted in the ED and four in the ICU) of which 52 studies included adults, 23 included children, and seven included both. Compared with midazolam-opioids, recovery time was shorter with propofol (mean difference 16.3 min, 95% confidence interval [CI] 8.4-24.3 fewer minutes; high certainty), and patient satisfaction was better with ketamine-propofol (mean difference 1.5 points, 95% CI 0.3-2.6 points, high certainty). Regarding AEs, compared with midazolam-opioids, respiratory AEs were less frequent with ketamine (relative risk [RR] 0.55, 95% CI 0.32-0.96; high certainty), gastrointestinal AEs were more common with ketamine-midazolam (RR 3.08, 95% CI 1.15-8.27; high certainty), and neurological AEs were more common with ketamine-propofol (RR 3.68, 95% CI 1.08-12.53; high certainty).
CONCLUSION
When considering procedural sedation and analgesia in the ED and ICU, compared with midazolam-opioids, sedation recovery time is shorter with propofol, patient satisfaction is better with ketamine-propofol, and respiratory adverse events are less common with ketamine.

Review
Dissolving microneedles (MN) with enhanced physiochemical properties are generating considerable interest as antibacterial delivery devices, which minimize hazardous sharp wastes, injuries, and transmission of blood-borne pathogens. This systematic review demonstrates and analyzes the current state of dissolvable antibacterial MN to establish their efficacy, and the effect of biomaterials selection on their final properties. A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three electronic databases Pubmed, Google scholar, and Scopus were explored for peer-reviewed articles. A total of 551 results with 176 citations and 915 references of resulted articles were reviewed and analyzed. No publication date restrictions were imposed. Last search was placed on 9th of June, 2021. The literature search in electronic databases according to the inclusion criteria was funneled down to 20 papers that were related to antibacterial effects of dissolving microneedles. In conclusion, all included dissolving MN studies presented an enhanced or at least an equal antibacterial activity against common bacterial species when compared to conventional treatments. In addition, composition modifications can enhance their activity and performance. Other factors such as the size and geometry of the produced MN can be tailored to conform to the infected site's characteristics.

Review
The methodological rigour of original studies on a diagnostic or prognostic research topic, and systematic reviews of these primary studies, varies; improving overall quality is warranted. This paper, the second of the series, outlines key concepts and essential steps required to conduct a high-quality systematic review on diagnostic topics. It is comprised of six aspects: clarifying the project objectives; generating an appropriate research question; searching the literature and selecting study criteria; assessing risk of bias of eligible studies, reporting and analyzing data, and interpreting data and making conclusions. This review emphasizes clarifying the role of the index test(s), including the "PIRO" components in a diagnostic research question, setting a hypothesis and threshold for an accurate test if needed, searching for existing systematic reviews, assessing the risk of bias for individual studies using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool, considering methodological heterogeneity before performing a meta-analysis, managing uninterpretable or inconclusive data, and assessing the overall quality of the aggregate evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. We believe clinicians and health researchers would benefit from this methodological training.

Meta-Analysis
AIMS
Resistant hypertension is associated with a high risk of cardiovascular disease, chronic kidney disease, and mortality. Yet, its management is challenging. This study aims to establish the comparative effectiveness of pharmacologic and interventional treatments by conducting a network meta-analysis.
METHODS AND RESULTS
MEDLINE, Cochrane Register of Controlled Trials, and Web of Science Core Collection were systematically searched in March 2022. Randomized controlled trials comparing treatment options for management of resistant hypertension were included. Outcomes were blood pressure (BP) changes, measured in the office and in 24 h ambulatory BP measurement. We applied a frequentist random effects model to perform a network meta-analysis combining placebo medication and sham procedure as the reference comparator. From 4771 records, 24 studies met the inclusion criteria with 3458 included patients in total. Twelve active treatment alternatives [spironolactone, doxazosin, β-blocker, clonidine, darusentan, guanfacine, various types of renal sympathetic denervation, lifestyle intervention, continuous positive airway pressure, and baroreflex activation therapy (BAT)] were analysed. Among all comparators, spironolactone had the highest ranking probability and was considered the most effective treatment to reduce office systolic blood pressure (sBP) [-13.30 mmHg (-17.89; -8.72); P < 0.0001] and 24 h sBP [-8.46 mmHg (-12.54; -4.38); P < 0.0001] in patients with resistant hypertension. Lifestyle interventions were the most effective non-pharmacological treatment, lowering office sBP by -7.26 mmHg (-13.73; -0.8), whereas BAT lowered office sBP by -7.0 (-18.59; 4.59). Renal denervation lowered office sBP by -5.64 mmHg (-12.95; 1.66) and -3.79 mmHg (-11.39; 3.8) depending on the type of the procedure.
CONCLUSION
Among all pharmacologic and interventional treatments, spironolactone is the most effective treatment in reducing BP in patients with resistant hypertension. More comparative trials and especially trials with long-term follow-up are needed. In the meanwhile, we have to conclude that a combination of spironolactone and lifestyle modification are the most effective treatments in resistant hypertension.
