Optical Coherence Tomography Angiography Changes in Patients Diagnosed With Acute Coronary Syndrome: A Systematic Review and Meta-Analysis.

We conducted a systematic review and meta-analysis to assess the association between optical coherence tomography angiography (OCTA) parameters and acute coronary syndrome (ACS). Two independent reviewers searched the electronic databases (MEDLINE (Medical Literature Analysis and Retrieval System Online), Scopus, Embase (Excerpta Medica Database), Cochrane Library, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform) from inception until April 2023. According to the inclusion criteria of this review, eligible were observational studies, randomized control trials, and registry/database studies that included the eyes of adult ACS patients and assessed OCTA parameters within the macula. The pooled standardized mean differences (SMD) between patients diagnosed with ACS and healthy controls with a confidence interval (CI) of 95% were calculated using the Hartung-Knapp-Sidik-Jonkman random-effects method. The heterogeneity was assessed by I2 and the Cochran Q and a random effects model was applied. Seven studies were eligible and included in our systematic review (n = 898), of which three were included in the meta-analysis (n = 341). The pooled SMD in the superficial vascular plexus (SVP), deep vascular plexus (DVP), and foveal avascular zone (FAZ) were -0.46 (95% CI: -0.94 to 0.01, p = 0.05, I2 = 0%, three studies), -0.10 (95% CI: -3.20 to 3.00, p = 0.75, I2 = 67%, two studies), and 0.43 (95% CI: -1.22 to 2.09, p = 0.38, I2 = 92%, three studies), respectively. Our findings suggest that there are no differences in OCTA metrics between ACS patients and healthy individuals.

UGH Syndrome Resolution after IOL Explantation and Concomitant Carlevale IOL Implantation.

OBJECTIVE: To examine the use of Carlevale IOL placement in patients with UGH, and to evaluate surgical outcomes. DESIGN: In this retrospective study, 28 patients with UGH syndrome that were subjected to IOL explantation and concomitant Carlevale IOL implantation were included in the study. METHODS: Information about VA, IOP, number of glaucoma medication, need for glaucoma surgery, presence of hemorrhage and inflammation were recorded up to 6 months after the procedure. RESULTS: We found a statistically significant increase in mean visual acuity and complete resolution of uveitis in all patients. Mean IOP and the mean number of glaucoma medications were significantly decreased postoperatively, while 14% of patients required additional glaucoma surgery. CONCLUSIONS: IOL explantation and concomitant Carlevale IOL implantation may provide a viable solution for UGH syndrome resolution, increases visual acuity, and decreases the need for glaucoma medication.

Health worker education during the COVID-19 pandemic: global disruption, responses and lessons for the future-a systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis identified early evidence quantifying the disruption to the education of health workers by the COVID-19 pandemic, ensuing policy responses and their outcomes. METHODS: Following a pre-registered protocol and PRISMA/AMSTAR-2 guidelines, we systematically screened MEDLINE, EMBASE, Web of Science, CENTRAL, clinicaltrials.gov and Google Scholar from January 2020 to July 2022. We pooled proportion estimates via random-effects meta-analyses and explored subgroup differences by gender, occupational group, training stage, WHO regions/continents, and study end-year. We assessed risk of bias (Newcastle-Ottawa scale for observational studies, RοB2 for randomized controlled trials [RCT]) and rated evidence certainty using GRADE. RESULTS: Of the 171 489 publications screened, 2 249 were eligible, incorporating 2 212 observational studies and 37 RCTs, representing feedback from 1 109 818 learners and 22 204 faculty. The sample mostly consisted of undergraduates, medical doctors, and studies from institutions in Asia. Perceived training disruption was estimated at 71.1% (95% confidence interval 67.9-74.2) and learner redeployment at 29.2% (25.3-33.2). About one in three learners screened positive for anxiety (32.3%, 28.5-36.2), depression (32.0%, 27.9-36.2), burnout (38.8%, 33.4-44.3) or insomnia (30.9%, 20.8-41.9). Policy responses included shifting to online learning, innovations in assessment, COVID-19-specific courses, volunteerism, and measures for learner safety. For outcomes of policy responses, most of the literature related to perceptions and preferences. More than two-thirds of learners (75.9%, 74.2-77.7) were satisfied with online learning (postgraduates more than undergraduates), while faculty satisfaction rate was slightly lower (71.8%, 66.7-76.7). Learners preferred an in-person component: blended learning 56.0% (51.2-60.7), face-to-face 48.8% (45.4-52.1), and online-only 32.0% (29.3-34.8). They supported continuation of the virtual format as part of a blended system (68.1%, 64.6-71.5). Subgroup differences provided valuable insights despite not resolving the considerable heterogeneity. All outcomes were assessed as very-low-certainty evidence. CONCLUSION: The COVID-19 pandemic has severely disrupted health worker education, inflicting a substantial mental health burden on learners. Its impacts on career choices, volunteerism, pedagogical approaches and mental health of learners have implications for educational design, measures to protect and support learners, faculty and health workers, and workforce planning. Online learning may achieve learner satisfaction as part of a short-term solution or integrated into a blended model in the post-pandemic future.

Current Approaches to the Management of Patients with Endometrial Cancer.

The incidence of endometrial cancer (EC) is rising and healthcare professionals need to be informed about the latest data on the constant developments in the field of its management. With particular interest in the classification and management of EC, we surveyed current literature, national and international data, and guidelines, as well as the latest studies to present the most recent data regarding the management of EC. It became evident that despite the consensus on low-risk EC, there are still controversies surrounding the management of high-risk EC, especially regarding the role of sentinel lymph node biopsy (SLNB). Our aim is to present the old and new perspectives in the management of EC, the different available surgical routes, the possible desire for fertility preservation, the role of adjuvant therapies and the focus on the advantages and the limitations of the implementation of SLNB in therapeutic strategies. It became evident throughout our search and based on literature data that minimally invasive surgery (MIS) leads to satisfying outcomes, thus becoming gradually the preferred route of surgery, while SLNB could provide essential information and guidance about the overall management needed in cases of both low-risk and high-risk EC.

A Review on Pathogens and Necessary Diagnostic Work for Bleb-Related Infections (BRIs).

At the present time, as newer techniques and minimally invasive procedures gain popularity among anterior segment surgeons for regulating intraocular pressure, trabeculectomy still has a leading role in glaucoma surgery. Trabeculectomy retains a highly successful and safe profile; however, one of the major complications includes bleb-related infections (BRIs). To date, the most common pathogens remain Gram-positive cocci, but the list of pathogens that have been identified in the literature includes more than 100 microorganisms. Because antibiotic use is more widespread than ever before and our ability to identify pathogens has improved, the pathogen spectrum will broaden in the future and more pathogens causing BRIs will be described as atypical presentations. The scope of this review was to identify all pathogens that have been described to cause bleb-related infections to date, as well as focus on the risk factors, clinical presentation, and various available diagnostic tools used for an appropriate diagnostic workup.

Cephalad-caudad versus transverse blunt expansion of the low transverse hysterotomy during cesarean delivery decreases maternal morbidity: a meta-analysis.

OBJECTIVE: Cesarean delivery is the most prevalent surgical procedure worldwide, reaching approximately 29.7 million cases in 2015. It is directly associated with an increased risk of maternal and neonatal morbidity rates in the absence of malpresentation. Several techniques have been investigated, and there is evidence that cephalad-caudad expansion of the uterine incision might be associated with improved maternal outcomes compared with traditional transverse blunt expansion. The purpose of this meta-analysis was to evaluate the impact of cephalad-caudad expansion on adverse maternal outcomes, including intraoperative blood loss, risk of uterine vessel injury, and tearing of the lower uterine segment. DATA SOURCES: We searched Medline, Scopus, the Cochrane Central Register of Controlled Trials, Google Scholar, and Clinicaltrials.gov databases from inception to January 2021. STUDY ELIGIBILITY CRITERIA: Randomized controlled trials that assessed the impact of the cephalad-caudad blunt expansion of the low transverse uterine incision during cesarean delivery rather than those of transverse blunt expansion were selected for inclusion. METHODS: Effect sizes were calculated with the Hartung-Knapp-Sidik-Jonkman random-effects model in R. Trial sequential analysis was performed to evaluate the adequacy of sample sizes. RESULTS: Cephalad-caudad blunt expansion of the uterine incision was associated with a lower prevalence of unintended incision extension (relative risk, 0.62; 95% confidence interval, 0.45-0.86) and uterine vessel injury (relative risk, 0.55; 95% confidence interval 0.41-0.73). However, these complications were not accompanied by the increased need for additional suture placement (relative risk, 0.62; 95% confidence interval, 0.31-4.12) or transfusion rates (relative risk, 0.75; 95% confidence interval, 0.28-2.03). Similarly, the intraoperative duration was comparable with cases treated with transverse blunt expansion (mean difference = -0.45 minutes; 95% confidence interval -2.12 to 1.21) and the risk of intentional incision extension in the form of an inverted T (relative risk, 0.38; 95% confidence interval, 0.09-1.52). Trial sequential analysis revealed that the required sample size was reached in the unintended incision extension and uterine vessel injury outcomes. CONCLUSION: The findings of our study suggested that cephalad-caudad blunt expansion of the uterine incision is superior to transverse expansion in terms of reducing unintended incision extension and uterine vessel injury.

Gender dysphoria in the field of obstetrics and gynecology.

Obstetrics/gynecology (OB/GYN) clinicians often manage gender dysphoric patients but frequently lack the necessary training. These individuals comprise a vastly heterogeneous group and gender clinics, staffed by multi-disciplinary teams, should become the standard of care, promoting a holistic approach. All OB/GYN clinicians need to be aware of basic aspects of gender dysphoria.

An arm-based network meta-analysis on treatments for vulvar lichen sclerosus and a call for development of core outcome sets.

OBJECTIVE: The purpose of the present systematic review is to evaluate the available medical treatments for vulvar lichen sclerosus, using an arm-based network meta-analysis protocol. DATA SOURCES: We searched Medline (1966-2019), Scopus (2004-2019), Cochrane Central Register of Controlled Trials CENTRAL (1999-2019), Clinicaltrials.gov (2008-2019) databases, and Google Scholar (2004-2019) database along with the reference list of all included studies. STUDY ELIGIBILITY CRITERIA: All observational, randomized, and single-arm studies that evaluated medical treatments for vulvar lichen sclerosus were considered eligible for inclusion in the present systematic review. STUDY APPRAISAL: A network meta-analysis was carried out in R 3.4.3 using the pcnetmeta package, which uses a Bayesian hierarchical model (based in Markov chain Monte Carlo convergence simulation). RESULTS: Sixteen studies were included in this present meta-analysis, which recruited 954 women with vulvar lichen sclerosus. Their quality was evaluated with the JADAD, Cochrane risk of bias, and risk of bias in nonrandomised studies of interventions-I tools. Clobetasol treatment ranked as the best treatment for disease remission after evaluating rank probabilities (40% chance of ranking first compared with tacrolimus [38%]). However, the density plot revealed partial overlapping with tacrolimus. The lowest probability of experiencing a relapse was observed with pimecrolimus (15% [2-48%]); however, the density plot revealed significant overlapping with mometasone furoate, testosterone, and clobetasol. CONCLUSION: Robust evidence concerning the superiority of potent steroids at least over calcineurin inhibitors is still lacking in the field of vulvar lichen sclerosus. On the other hand, the gross heterogeneity in terms of selected population, duration of treatment, administered regimen, outcome reporting, and selection of outcome measures leaves several fields unanswered.

Experimental hypogonadism: insulin resistance, biochemical changes and effect of testosterone substitution.

Background We sought to clarify the role of testosterone substitution in terms of insulin resistance and metabolic profile dysregulation in hypogonadism. Methods Twenty-nine male Wistar rats aged 11-12 weeks were divided in three groups: control (C, n = 10), sham operation; orchiectomy (ORX, n = 9); and orchiectomy + testosterone substitution (ORX+T, n = 10). Blood samples were obtained at day 1 (operation), after 10 days (intramuscular T injection 100 µg/100 g b.w.), 25 days (second T injection) and 40 days (sacrifice). Results Hormonal replacement significantly attenuated the negative effect of orchiectomy on insulin resistance as indicated by the successive changes in both insulin levels (1.44 ± 2.94 vs. 4.10 ± 2.47 vs. 1.78 ± 0.68 ng/mL, for D1, D10 and D40, respectively; p = 0.028 and p = 0.022, respectively) and HOMA-IR index (1.36 ± 2.75 vs. 3.68 ± 1.87 vs. 1.74 ± 0.69 ng/mL, for D1, D10 and D40, respectively; p = 0.024 and p = 0.026, respectively) in the ORX+T group. Irisin levels peaked at the 10th postoperative day and were decreased at the end of the experiment (0.27 ± 0.11 vs. 0.85 ± 0.54 vs. 0.02 ± 0.07 ng/mL for D1, D10 and D40, respectively; p = 0.028 in both cases), whereas resistin levels did not differ. Experimental hypogonadism results in an unfavorable lipid profile and insulin resistance, which is not observed when the ORX animals are substituted for T.

Defining the Optimal Dietary Approach for Safe, Effective and Sustainable Weight Loss in Overweight and Obese Adults.

Various dietary approaches with different caloric content and macronutrient composition have been recommended to treat obesity in adults. Although their safety and efficacy profile has been assessed in numerous randomized clinical trials, reviews and meta-analyses, the characteristics of the optimal dietary weight loss strategy remain controversial. This mini-review will provide general principles and practical recommendations for the dietary management of obesity and will further explore the components of the optimal dietary intervention. To this end, various dietary plans are critically discussed, including low-fat diets, low-carbohydrate diets, high-protein diets, very low-calorie diets with meal replacements, Mediterranean diet, and diets with intermittent energy restriction. As a general principle, the optimal diet to treat obesity should be safe, efficacious, healthy and nutritionally adequate, culturally acceptable and economically affordable, and should ensure long-term compliance and maintenance of weight loss. Setting realistic goals for weight loss and pursuing a balanced dietary plan tailored to individual needs, preferences, and medical conditions, are the key principles to facilitate weight loss in obese patients and most importantly reduce their overall cardiometabolic risk and other obesity-related comorbidities.
