Perioperative intravenous lidocaine infusion improves postoperative analgesia after hysterectomy: A systematic review and meta-analysis of randomized controlled trials.

The effectiveness of intravenous lidocaine in reducing acute pain after hysterectomy remains uncertain. We conducted a meta-analysis of randomized controlled trials (RCTs) to investigate the impact of intravenous lidocaine on post-hysterectomy recovery. This study was completed based on the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. A systematic search was conducted in PubMed/MEDLINE, the Cochrane Controlled Trials Register (CENTRAL), and Embase up to July 27, 2023. We identified randomized controlled trials (RCTs) involving hysterectomy patients comparing lidocaine to a placebo. Outcome measures included postoperative pain scores at rest and during movement, opioid consumption, postoperative nausea and vomiting (PONV), improvements in functional gastrointestinal recovery, and Quality of Recovery (QoR) scores. Nine RCTs were included in the meta-analysis, comprising 352 patients who received intravenous lidocaine and 354 controls. The analysis revealed that intravenous lidocaine significantly reduced postoperative pain scores at rest at 2, 6, 8, and 24 hours following hysterectomy, as well as postoperative opioid consumption within 24 hours and PONV rates. Furthermore, no observed benefit was noted in shortening the time to first flatus with intravenous lidocaine administration post-hysterectomy. Intravenous lidocaine administration effectively reduces acute postoperative pain, opioid consumption, and PONV rates following hysterectomy. Lidocaine serves as an opioid-sparing agent, reducing the morphine equivalent dose while maintaining a similar degree of postoperative pain.

P-405 Effects of intrauterine perfusion of autologous platelet-rich plasma on recurrent implantation failure in frozen-thawed embryo transfer: a meta-analysis of randomized controlled trials

Abstract Study question We aimed to evaluate the effect of the platelet-rich plasma （PRP) on pregnancy outcomes in patients with RIF undergoing frozen-thawed embryo transfer (FET). Summary answer Intrauterine infusion of PRP might have more beneficial effects on pregnancy outcomes in RIF patients undergoing FET. What is known already Immunological therapies are of great interest to specialists in reproductive medicine. The immune therapies use intrauterine infusion (i.e., PRP, PBMC, G-CSF, and hCG) for endometrial immunomodulation. Despite the limited number of publications available, the results are encouraging. In the network meta-analysis, PRP, PBMC, C-GCSF, and hCG administration all significantly increased embryo implantation and clinical pregnancy compared to controls. Additionally, PRP administration resulted in a higher live birth rate than the control. This year, more research has focused on PRP as an innovative method to treat RIF. Study design, size, duration Medline, Embase, and Cochrane Controlled Register of Trials (CENTRAL) were searched from inception to July 29, 2023. The randomized controlled trials (RCTs) reporting on pregnancy outcomes of women with RIF who were administered PRP undergoing FET were included. We conducted a meta-analysis where possible using a fixed effects model. The Cochrane Handbook was used to assess the risk of bias for RCTs. Binary outcomes were pooled using risk ratio (RR) with 95% confidence intervals (CIs). Participants/materials, setting, methods Seven RCTs were included with 1,014 RIF women. The final number of women analyzed was 508 with intrauterine infusion PRP and 506 without it. Main results and the role of chance Meta-analysis showed that compared to the controls, the women who received PRP had a significantly higher embryo implantation rate (n = 2, risk ratio (RR) 2.34, 95% CI 1.65 to 3.32; P < 0.00001, I2 = 0%), biochemical pregnancy rate (n = 5, RR 1.94, 95% CI 1.60 to 2.36; P < 0.00001, I2 = 0%), clinical pregnancy rate (n = 7, RR 2.31, 95% CI 1.89 to 2.82; P < 0.00001, I2 = 0%), ongoing pregnancy rate (n = 3, RR 2.70, 95% CI 1.79 to 4.05, P = 0.0004, I2 = 31%), and multiple pregnancy rate (n = 3, RR 2.67, 95% CI 1.07 to 6.68, P = 0.04, I2 = 0%). However, PRP was not attributable to reduce the miscarriage rate (n = 3, RR 1.15, 95% CI 0.40 to 3.35; P = 0.80, I2 = 0%). Limitations, reasons for caution The proportion of small-sample studies included has to some extent affected the validity of the results. There were some variations regarding the PRP preparation process, which may result in a variable composition and concentrations of its different contents. Wider implications of the findings Intrauterine infusion PRP in patients with RIF who underwent FET may improve the pregnancy outcomes assessed in RCTs, including clinical pregnancy and ongoing pregnancy. Therefore, we suggest that PRP be included in endometrial preparation protocols. Trial registration number not applicable

37 Evaluation of Prophylactic Negative Pressure Wound Therapy Versus Standard Surgical Dressings on Wound Outcomes in Posterior Spinal Surgery Patients: A Systematic Review and Meta-Analysis

Abstract Aim Negative pressure wound therapy has frequently been used in a variety of surgical specialities, yet its effectiveness as a prophylactic therapy in spinal surgery remains unclear. A comprehensive systematic review and meta-analysis was performed, incorporating the most recent evidence, addressing this paucity in the literature. Method A systematic search of the literature from inception to June 2023 was conducted using the following databases: Ovid Medline, EMBASE, Cochrane Register of Controlled Trials (CENTRAL) and Web of Science. All included studies assessed primary wound closure for posterior spinal surgical incisions. Evidence was quality assessed and outcomes of interest were meta-analysed using odds ratios, comparing negative pressure wound therapy and standard dressing groups. Results Seven studies (n = 1319, mean age = 59.9 years, 55.8% male) were included. Patients with negative pressure dressings had a reduced risk of surgical site infection (odds ratio = 0.45, 95% CI 0.29 to 0.72, p < 0.001). Wound dehiscence approached significance favouring negative pressure dressings (odds ratio = 0.53, 95% CI 0.26 to 1.06, p = 0.07). Patients requiring a return to theatre for wound related complications showed no significant difference between groups (odds ratio = 0.66, 95% CI 0.37 to 1.18, p = 0.16). Conclusions Negative pressure wound therapy reduces the risk of surgical site infection in posterior spinal surgery patients. Given that surgical site infection in spine surgery is associated with significant morbidity and financial costs, implementation of prophylactic negative pressure wound therapy for this patient demographic may be beneficial.

Association of Polycystic Ovarian Syndrome (PCOS) With Vaginal Microbiome Dysbiosis: A Scoping Review.

The aim of this scoping review was to explore the potential relationship between vaginal microbiome dysbiosis and polycystic ovarian syndrome (PCOS). Four databases were utilized to identify primary literature based on a pre-determined exclusion and inclusion criteria. The electronic databases searched include MEDLINE, Embase, Cochrane Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science. After an initial double-blind screening and removal of duplicates, 81 articles remained. Articles were included based on preselected inclusion and exclusion criteria, type of study, and date of publishing. Specifically, primary literature that focused on subjects that were diagnosed with PCOS and that discussed PCOS in relation to the vaginal microbiome was included. Literature reviews, studies with animal subjects, and studies that did not discuss PCOS and the vaginal microbiome were excluded. Current data from the five articles included in this review suggests that there is a relationship between PCOS and vaginal microbiome dysbiosis. Specifically, dysbiosis of the vaginal flora may be due to vaginal pH alterations secondary to decreased vaginal Lactobacillus species and elevated pathogenic species including Streptococcus, Actinomyces, Prevotella, Gardnerella, and Mycoplasma species. The manifestation of this vaginal microbiome dysbiosis is often bacterial and fungal vaginitis.Therefore, more studies are needed to explore the possibility of treating PCOS with probiotics designed to reestablish a healthy Lactobacillus-dominant vaginal microbiome. In addition, further studies on the microbial composition of the vaginal microbiota in PCOS patients could identify microbial biomarkers for diagnosing PCOS.

Stress reduction through taiji: a systematic review and meta-analysis

PurposeIn light of the mounting prevalence of stress in contemporary society and the growing interest in stress reduction methods, this review investigates the potential of taiji as a viable strategy for alleviating stress.MethodsMEDLINE, EMBASE, the Cochrane Controlled Trials Register (CENTRAL), PsycINFO, and Web of Science were searched up to April 2023 to identify randomized controlled trials of taiji. Studies in both patients and healthy populations were considered. They had to provide a measure of perceived stress and include a no treatment or placebo control group. Data were extracted by two reviewers. Pooled standardized mean differences (SMD) were calculated for perceived stress, biological stress markers, anxiety, depression, and quality of life (QoL). Meta-regression analyses were performed to identify sources of heterogeneity.ResultsEleven trials with a total of 1323 patients comparing taiji to no intervention met the inclusion criteria. The included studies varied strongly with regard to patient characteristics, taiji intervention, and methodological quality. The overall SMD for perceived stress was significant at -0.41 (95% confidence interval, CI, -0.63 to -0.19; I2 = 63%). Exclusion of studies with less than 100 participants yielded a diminished SMD at -0.26 (95% CI, -0.45 to -0.06). The SMD for perceived stress at follow-up was significant (-0.25, 95% CI -0.46 to -0.05). Secondary outcomes highlighted improvements in anxiety and physical QoL, while depression, mental QoL, and biological stress markers remained unchanged.ConclusionsResults underscore taiji's potential in mitigating perceived stress in both patients and healthy populations, paralleled by enhancements in depressive symptoms, anxiety levels, and physical QoL.

Primary prevention of atrial fibrillation with pharmacological therapy

Abstract Background Primary prevention of atrial fibrillation (AF) is important given its rising incidence, associated disease burden, and cost (1-3). The effect of pharmacological therapies on incidence of new-onset AF is uncertain, (1) leading to an absence of clear guideline recommendations for prevention of AF (3). Purpose To perform a meta-analysis of the effect of pharmacological therapies on new-onset AF as reported in published randomised clinical trials (RCTs), and investigate for changes by individual agents and clinically relevant subgroups. Methods We performed a systematic review of RCTs that evaluated the relationship between a pharmacological therapy and the development of new-onset AF in a non-hospitalised patient cohort, using Medline, Embase and Cochrane-controlled Trials Register from inception through 19 July 2023. Results of the AF outcome are expressed as relative ratio (RR) with 95% confidence interval (CI) between the intervention and control group for each study. A fixed-effect model was used to combine results from studies when I2<50% and random-effect model when I2>50%. Risk of bias was assessed using the Cochrane RoB2 tool. Meta-regression was performed by mean age of study participants, percentage of men, follow-up duration, indication (e.g. heart failure) and each agent. Results From 11872 unique records we included 101 RCTs with 794775 patients. Overall, risk of bias was considerable (48% high, 35% medium); driven by outcome measurement (67% high/medium) as AF was not the primary outcome of studies. Of pharmacological therapies, patients treated with angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) demonstrated a lower risk of AF compared with controls (RR 0.87, 95% CI 0.78-0.98), and patients treated with omega-3 fatty acids demonstrated a higher risk of AF (RR 1.26, 95% CI 1.11-1.42) (Figure 1). Analysis by indication demonstrated that the reduction in AF risk with treatment with ACEIs/ARBs was only for patients with heart failure with reduced ejection fraction (HFrEF) (RR 0.57, 95% CI 0.34-0.94). Amongst individual ACEIs/ARBs, only treatment with valsartan (RR 0.79, 95% CI 0.66-0.95) and olmesartan (RR 0.87, 95% CI 0.45-0.99) led to a lower risk of AF. On meta-regression each year of increased age increased AF risk when treated with ACE-I/ARB therapy (RR 1.08, 95% CI 1.04-1.13). Whilst no reduction in AF was observed for other pharmacological classes overall, treatment with Semaglutide demonstrated a 40% lower risk of AF compared with controls (RR 0.60, 95% CI 0.45-0.80) (Figure 2). Conclusions ACEIs and ARBs appear to be effective in the primary prevention of AF, but this benefit may be limited to patients with HFrEF, especially younger patients. Effect on AF occurrence varies within pharmacological classes, and Semaglutide specifically may be an effective in preventing new-onset AF. Appropriately powered RCTs with new-onset AF as the primary outcome are required.Figure 1:Forest plot by pharmacotherapyFigure 2:Forest plot by GLP-1RA agent

Evaluation of quality and quantity of randomized controlled trials in hepatobiliary surgery: A scoping/mapping review.

To evaluate the quantity and quality of randomized controlled trials (RCTs) in hepatobiliary surgery and for identifying gaps in current evidences. A systematic search was conducted in MEDLINE (via PubMed), Web of Science, and Cochrane Controlled Register of Trials (CENTRAL) for RCTs of hepatobiliary surgery published from inception until the end of 2023. The quality of each study was assessed using the Cochrane risk-of-bias (RoB) tool. The associations between risk of bias and the region and publication date were also assessed. Evidence mapping was performed to identify research gaps in the field. The study included 1187 records. The number and proportion of published randomized controlled trials (RCTs) in hepatobiliary surgery increased over time, from 13 RCTs (.0005% of publications) in 1970-1979 to 201 RCTs (.003% of publications) in 2020-2023. There was a significant increase in the number of studies with a low risk of bias in RoB domains (p < .01). The proportion of RCTs with low risk of bias improved significantly after the introduction of CONSORT guidelines (p < .001). The evidence mapping revealed a significant research focus on major and minor hepatectomy and cholecystectomy. However, gaps were identified in liver cyst surgery and hepatobiliary vascular surgery. Additionally, there are gaps in the field of perioperative management and nutrition intervention. The quantity and quality of RCTs in hepatobiliary surgery have increased over time, but there is still room for improvement. We have identified gaps in current research that can be addressed in future studies.

Which Portion of Physiotherapy Treatments' Effect Is Not Attributable to the Specific Effects in People With Musculoskeletal Pain? A Meta-Analysis of Randomized Placebo-Controlled Trials.

OBJECTIVE: We aimed to quantify the proportion not attributable to the specific effects (PCE) of physical therapy interventions for musculoskeletal pain. DESIGN: Intervention systematic review with meta-analysis. LITERATURE SEARCH: We searched Ovid, MEDLINE, EMBASE, CINAHL, Scopus, PEDro, Cochrane Controlled Trials Registry, and SPORTDiscus databases from inception to April 2023. STUDY SELECTION CRITERIA: Randomized placebo-controlled trials evaluating the effect of physical therapy interventions on musculoskeletal pain. DATA SYNTHESIS: Risk of bias was evaluated using the Cochrane risk-of-bias tool for randomized trials (RoB 2). The proportion of physical therapy interventions effect that was not explained by the specific effect of the intervention was calculated, using the proportion not attributable to the specific effects (PCE) metric, and a quantitative summary of the data from the studies was conducted using the random-effects inverse-variance model (Hartung-Knapp-Sidik-Jonkman method). RESULTS: Sixty-eight studies were included in the systematic review (participants: n = 5238), and 54 placebo-controlled trials informed our meta-analysis (participants: n = 3793). Physical therapy interventions included soft tissue techniques, mobilization, manipulation, taping, exercise therapy, and dry needling. Placebo interventions included manual, nonmanual interventions, or both. The proportion not attributable to the specific effects of mobilization accounted for 88% of the immediate overall treatment effect for pain intensity (PCE = 0.88, 95% confidence interval [CI]: 0.57, 1.20). In exercise therapy, this proportion accounted for 46% of the overall treatment effect for pain intensity (PCE = 0.46, 95% CI: 0.41, 0.52). The PCE in manipulation excelled in short-term pain relief (PCE = 0.81, 95% CI: 0.62, 1.01) and in mobilization in long-term effects (PCE = 0.86, 95% CI: 0.76, 0.96). In taping, the PCE accounted for 64% of disability improvement (PCE = 0.64, 95% CI: 0.48, 0.80). CONCLUSION: The outcomes of physical therapy interventions for musculoskeletal pain were significantly influenced by factors not attributable to the specific effects of the interventions. Boosting these factors consciously to enhance therapeutic outcomes represents an ethical opportunity that could benefit patients. J Orthop Sports Phys Ther 2024;54(6):391-399.

Silver Diamine Fluoride (SDF) in the management of root caries in elders: a systematic review and meta-analysis.

This systematic review was undertaken to address the PICO question: Is silver diamine fluoride (SDF) effective in preventing and arresting root caries lesions in (RCLs) elders? Systematic literature searches were conducted of electronic databases [PubMed, Embase, and CENTRAL (Cochrane Controlled Register of Trials)] and hand searches were performed to identify studies reporting on the use of SDF in elders to prevent and arrest root caries. Prospective clinical studies were included. Two independent investigators performed the literature search and data extraction. A total of 277 studies were identified; of those 3 randomized controlled clinical trials were included for data extraction and analysis. A meta-analysis, using a fixed-effects model, was performed on the mean active RCLs present after SDF intervention compared to controls at 24 months (3 studies), and 30-36 months (2 studies) post-intervention. The fixed-effects model revealed a significant decrease in the mean new active RCLs post intervention with SDF compared to controls at both 24 months (95%CI: 0.265 - 0.638; I2=0.0%; Overall: Z=4.749, p<0.001), and at 30-36 months (95%CI: 0.329 - 0.812; I2=0.0%; Overall: Z=4.629, p<0.001). A funnel plot ruled out any publication bias and the risk of bias was judged to be low. This systematic review and meta-analysis provides evidence that the application of silver diamine fluoride prevents and arrests root caries in elders.

The Efficacy of Metformin as a Therapeutic Agent in the Treatment of Acne Vulgaris: A Systematic Review.

A large portion of the world's population is affected by acne vulgaris (AV), with many of these individuals being adolescents. The underlying mechanism of AV is hyperkeratinization and Cutibacterium acnes infection of the pilosebaceous follicle secondary to excessive stimulation of sebaceous glands by androgens. Metformin is a biguanide medication primarily used in efforts to lower patients' sugar levels in the management of type 2 diabetes. It has been proven to reduce levels of circulating androgens in patients with insulin resistance, indicating its potential for treating AV. A search strategy was developed and performed using the databases Ovid Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Controlled Register of Trials (CENTRAL), and Web of Science. The keywords "metformin" and "acne" were searched, along with related Medical Subject Headings (MeSH) and other subject headings. Studies that met the inclusion criteria were controlled trials, published after 2010, and in the English language. Participants with and without comorbidities such as polycystic ovary syndrome (PCOS) were considered. Two independent reviewers screened studies based on predefined criteria and extracted data from each study, which were quantitatively combined. A total of 15 studies were included in this systematic review. Across the 15 studies, there were 1,046 participants, with 13 studies looking exclusively at women with PCOS. Of the remaining two studies, one examined males with altered metabolic profiles, while the other included men and women with moderate AV. Notable risks of bias included studies that did not exclusively state the blindness of the study. Of the studies that were examined, 13 showed that metformin reduces AV, with seven studies showing statistical significance. Acne vulgaris is an inflammatory condition that has plagued patients for years due to the limited treatment options available. The hyperglycemic medication metformin, used in the management of type 2 diabetes, is being explored as a novel therapeutic that can possibly be repurposed for the treatment of AV. The use of metformin in AV is hypothesized to disrupt the proposed linkage between insulin resistance and AV proliferation. This proposed research could offer physicians a new option for the treatment of AV as well as render an alternative AV treatment for patients.

Pharmacotherapy to Improve Cognitive Functioning After Acquired Brain Injury: AMeta-Analysis and Meta-Regression.

Cognitive impairments, common sequelae of acquired brain injury (ABI), significantly affect rehabilitation and quality of life. Currently, there is no solid evidence-base for pharmacotherapy to improve cognitive functioning after ABI, nevertheless off-label use is widely applied in clinical practice. This meta-analysis and meta-regression aims to quantitatively aggregate the available evidence for the effects of pharmacological agents used in the treatment of cognitive impairments following ABI. We conducted a comprehensive search of Embase, Medline Ovid, and Cochrane Controlled Trials Register databases for randomized controlled and crossover trials. Meta-analytic effects were calculated for each pharmaceutical agent and targeted neuromodulator system. Cognitive outcome measures were aggregated across cognitive domains. Of 8,216 articles, 41 studies (4,434 patients) were included. The noradrenergic agent methylphenidate showed a small, significant positive effect on cognitive functioning in patients with traumatic brain injury (TBI; k = 14, d = 0.34, 95% confidence interval: 0.12-0.56, P = 0.003). Specifically, methylphenidate was found to improve cognitive functions related to executive memory, baseline speed, inhibitory control, and variability in responding. The cholinergic drug donepezil demonstrated a large effect size, albeit based on a limited number of studies (k = 3, d = 1.68, P = 0.03). No significant effects were observed for other agents. Additionally, meta-regression analysis did not identify significant sources of heterogeneity in treatment response. Our meta-analysis supports the use of methylphenidate for enhancing cognitive functioning in patients with TBI. Although donepezil shows potential, it warrants further research. These results could guide clinical decision making, inform practice guidelines, and direct future pharmacotherapeutic research in ABI.

Auto-hematopoietic stem cell transplantation or chemotherapy? Meta-analysis of clinical choice for AML.

For patients with acute myeloid leukemia (AML) who are not candidates for allogeneic stem cell transplantation (SCT) or do not have a human leukocyte antigen (HLA)-matched donor, it is unclear whether autologous SCT (ASCT) has a better prognosis after the first complete response (CR1) compared to further chemotherapy treatment. A meta-analysis evaluating ASCT compared to further chemotherapy for AML patients in CR1 was performed. The Medline, Embase, Cochrane Controlled Trials Registry, Cochrane Library, Web of Science, and National Knowledge Infrastructure of China databases were searched for relevant literature as of May 26, 2023. Eligible studies included prospectively enrolled adults with AML and randomized first-time respondent patients who did not have a matched sibling donor. Fourteen randomized controlled trials were identified and included 4281 participants, of which 1499 patients received ASCT and 2782 underwent chemotherapy and continued follow-up. In patients with AML in CR1, a lower relapse rate was associated with ASCT compared to chemotherapy [odds ratio (OR) = 0.49, 95% confidence interval (CI) = 0.41-0.57]. Significant disease-free survival (DFS; OR = 1.37, 95% CI = 1.02-1.84) and relapse-free survival (RFS; OR = 2.78, 95% CI = 1.28-6.02) ASCT benefits were documented, and there was no difference in the overall survival (OS) when the studies were pooled (OR = 1.12, 95% CI = 0.85-1.48). The study results indicated that after the first remission, AML patients receiving autologous stem cell transplantation had higher DFS and RFS, similar OS, and lower relapse compared to patients undergoing chemotherapy treatment. This indicated that autologous stem cell transplantation may have a better prognosis.

Teaching Strategies for Developing Clinical Reasoning Skills in Nursing Students: A Systematic Review of Randomised Controlled Trials.

Clinical reasoning (CR) is a holistic and recursive cognitive process. It allows nursing students to accurately perceive patients' situations and choose the best course of action among the available alternatives. This study aimed to identify the randomised controlled trials studies in the literature that concern clinical reasoning in the context of nursing students. A comprehensive search of PubMed, Scopus, Embase, and the Cochrane Controlled Register of Trials (CENTRAL) was performed to identify relevant studies published up to October 2023. The following inclusion criteria were examined: (a) clinical reasoning, clinical judgment, and critical thinking in nursing students as a primary study aim; (b) articles published for the last eleven years; (c) research conducted between January 2012 and September 2023; (d) articles published only in English and Spanish; and (e) Randomised Clinical Trials. The Critical Appraisal Skills Programme tool was utilised to appraise all included studies. Fifteen papers were analysed. Based on the teaching strategies used in the articles, two groups have been identified: simulation methods and learning programs. The studies focus on comparing different teaching methodologies. This systematic review has detected different approaches to help nursing students improve their reasoning and decision-making skills. The use of mobile apps, digital simulations, and learning games has a positive impact on the clinical reasoning abilities of nursing students and their motivation. Incorporating new technologies into problem-solving-based learning and decision-making can also enhance nursing students' reasoning skills. Nursing schools should evaluate their current methods and consider integrating or modifying new technologies and methodologies that can help enhance students' learning and improve their clinical reasoning and cognitive skills.

The effect of intraoperative fluoroscopy on acetabular component positioning and patient anatomy restoration during posterior or posterolateral approach total hip arthroplasty: a meta-analysis.

Positioning implant components and restoring patient anatomy during total hip arthroplasty (THA) are essential for joint stability, polyethylene liner wear, and range of motion. Previous studies comparing intraoperative fluoroscopy with no fluoroscopy during the posterior or posterolateral approach have reported conflicting results. This meta-analysis evaluated if intraoperative fluoroscopy improves component positioning and femoral component position compared to no fluoroscopy during posterior or posterolateral approach total hip arthroplasty. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards were followed when conducting the systematic review. We searched Web of Science, Embase, PubMed, Cochrane Controlled Trials Register, Cochrane Library, Highwire, CBM, CNKI, VIP, and Wanfang database in May 2023 to identify studies involving Intraoperative fluoroscopy versus no fluoroscopy during posterior or posterolateral approach total hip arthroplasty. Finally, we identified 1133 patients (1145 hips) assessed in seven studies. There were no significant differences in terms of acetabular cup inclination angle (ACIA, P = 0.43), ACIA within safe zone rate (P = 0.58), acetabular cup anteversion angle (ACAA, P = 0.46); ACAA within safe zone rate (P = 0.72), Combined safe zone rate (P = 0.28), dislocation rate (P = 0.64) and infection rate (P = 0.94) between two groups. Compared with the no fluoroscopy group, the intraoperative fluoroscopy group had more operation time (P < 0.00001), less femoral component offset difference (FCOD, P = 0.03), and less LLD (P < 0.00001). Even though intraoperative fluoroscopy was not related to an improvement in cup location or dislocation incidence. Our findings demonstrate that the restoration of leg lengths and femoral offset can be significantly improved by using intraoperative fluoroscopy to supplement good surgical skills in THA. The advantages of intraoperative fluoroscopy might become more apparent for surgeons with less experience. To ascertain whether intraoperative fluoroscopy for posterior or posterolateral approach total hip arthroplasty will have clinical benefits and improve the survival of prostheses, more well-powered and well-designed long-term follow-up studies were necessary.

PP130 The Effectiveness Of Extracorporeal Shock Wave Therapy For Plantar Fasciitis: A Systematic Review And Meta-analysis

IntroductionExtracorporeal shock wave therapy (ESWT) has been used since the 1990s to treat various musculoskeletal disorders, but there is considerable controversy regarding the effectiveness of ESWT. Our aim was to conduct a systematic review of randomized controlled trials (RCT) to investigate the effectiveness of ESWT for plantar fasciitis.MethodsA comprehensive search was conducted via electronic databases including MEDLINE, Embase, the Cochrane Controlled trials register, and 5 Korean databases from inception date to April 2022. Two review authors independently assessed studies for inclusion and risk of bias, and extracted study data. Major outcomes were pain relief, function, and quality of life.ResultsWe identified a total of 48 RCTs comparing ESWT with corticosteroid injection (n=14), conventional therapies (n=19), and sham control (n=21). Most studies included participants with chronic heel pain diagnosed as plantar fasciitis. All trials were susceptible to bias. In terms of pain results, ESWT showed no significant difference when compared with the steroid injection group and the conventional therapy group, and significant pain relief was confirmed only compared to the sham control group (Mean Difference -1.71; 95% confidence interval [CI] -2.44,-0.98; I2=70%;). Functional outcomes were significantly improved in the ESWT group compared to the steroid injection group (standardized mean difference 0.45; 95% CI 0.27,0.63; I2=0%) and the sham control group (SMD 0.84, 95% CI 0.23,1.45; I2=91%), but no significant difference was found when compared to the conventional therapy group.ConclusionsBased upon the currently available low certainty evidence because of wide clinical diversity and varying treatment protocols of included trials, ESWT is associated with improved function and may be associated with pain reduction in plantar fasciitis. Further evidence is needed from well-designed studies with a standard dose and treatment protocol.

A Meta-Analysis of Short-Term Outcomes of TAVR versus SAVR in Bicuspid Aortic Valve Stenosis and TAVR Results in Different Bicuspid Valve Anatomies

Background: To provide a comprehensive analysis of the current literature comparing the outcomes of surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic stenosis (BAS), with particular attention to BAV morphology in patients undergoing TAVR. Methods: Following PRISMA guidelines, all relevant articles with no design restrictions from PubMed, CCTR (Cochrane Controlled Trials Register), and Google Scholar were screened for inclusion. Studies were included if they reported clinical endpoints for SAVR and TAVR or, in BAS treated with TAVR, for type 1 and non-type 1 morphology. Odds ratio and Cohen’s D were considered as effect size measurements for qualitative and quantitative variables, respectively. Results: A total of eight studies comparing short-term outcomes between SAVR and TAVR and nine studies with outcomes data between type 1 and non-type 1 BAS treated with TAVR were considered for the final analysis. No statistically significant difference was found for what concerns the rates of death, stroke, and acute kidney injury between SAVR and TAVR. In comparison to patients undergoing SAVR, the incidence of PPI (permanent pacemaker implantation) was greater in the TAVR group (OR 0.35, 95% CI 0.15–0.79, p = 0.01), and the frequency of bleeding events was found to be higher among patients undergoing SAVR (OR 4.3, 95% CI 2.9–6.4, p &lt; 0.001). The probabilities of 30-day mortality, stroke, and any bleeding were not significantly affected by bicuspid valve morphology in TAVR patients. PPI or development of new conduction anomalies was found to be more frequent in type 1 anatomies (OR 0.46, 95% CI 0.30–0.70, p &lt;0.001). Mildly lower post-procedural transprothesic gradients were found in patients with type 1 morphology. Conclusions: In BAS patients, TAVR has comparable short-term outcomes rates with SAVR, but higher PPI rates and lower incidence of bleeding events. In patients undergoing TAVR, type 1 BAS is associated with lower postoperative transvalvular gradients but higher PPI rates and conduction abnormalities

Reference standards for stress radiography measurements in knee ligament injury and instability: a systematic review

AbstractPurposeStress radiographs are an easily accessible, cost‐effective tool in the evaluation of acute and chronic ligament knee injuries. Stress radiographs provide an objective, quantifiable, and functional assessment of the injured ligament and can be a useful adjunct when planning surgical management and to objectively assess postoperative outcomes. This study aimed to review the literature reporting on stress radiographic techniques in evaluating knee ligament injury and instability and propose thresholds for interpreting stress radiography techniques.MethodsThe following three databases, OVID MEDLINE, the EMBASE library, and the Cochrane Controlled Trials Register, were systematically searched on January 23, 2023, for studies published from January 1970 to January 2023. The search extended to the reference lists of all relevant studies and orthopedic journals. Included studies were those that described a stress technique for the diagnosis of knee ligament injury; studies that reported a description or comparison of the accuracy and/or reliability of one or several stress radiography techniques, or studies that reported a comparison with alternative diagnostic modalities.ResultsSixteen stress radiography techniques were reported for assessing the ACL with stress applied in the anterior plane, 10 techniques for assessing the PCL with stress applied in the posterior plane, 3 techniques for valgus stress, and 4 techniques for varus stress. The Telos device was the most commonly used stress device in the ACL and PCL studies. There was no consensus on the accuracy and reliability of stress radiography techniques for the diagnosis of any knee ligament injury. Stress radiography techniques were compared with alternative diagnostic techniques including instrumented arthrometry, MRI, and physical examination in 18 studies, with variability in the advantages and disadvantages of stress radiography techniques and alternatives. Analysis of results pooled from different studies demonstrated average delta gapping in knees with a completely injured ligament compared to the normal contralateral knee as per the following: for the ACL 4.9 ± 1.4 mm; PCL 8.1 ± 2.5 mm; MCL 2.3 ± 0.05 mm; and the FCL 3.4 ± 0.2 mm.ConclusionDespite heterogeneity in the available literature with regard to stress examination techniques and device utilization, the data support that stress radiography techniques were accurate and reliable when compared to numerous alternatives in the diagnosis of acute and chronic knee ligament injuries. The present study also provides average increased ipsilateral compartment gapping/translation for specific knee ligament injuries based on the best available data. These values provide a reference standard for the interpretation of stress radiography techniques, help to guide surgical decision‐making, and provide benchmark values for future investigations.Level of evidenceIII.

Role and efficacy of capecitabine in the anthracycline-free regimen in breast cancer patients: a systematic review and meta-analysis.

Capecitabine has extensive utilization in the treatment of diverse solid tumors, and its efficacy has been substantiated. Its oral administration and minimal toxicity in clinical practice render it advantageous. Nevertheless, uncertainty remains regarding whether capecitabine can substitute anthracycline drugs in chemotherapy regimens to achieve a lower risk of anthracycline-induced degradation. Consequently, we conducted a meta-analysis of randomized controlled trials (RCTs) to assess the potential of capecitabine as a replacement for anthracycline drugs in chemotherapy regimens for breast cancer. We systematically searched PubMed, Embase, Web of Science, and the Cochrane Controlled Trials Register (CENTRAL) to retrieve eligible studies published before July 18, 2023. Two independent reviewers extracted relevant data from the included studies using a pre-established data extraction form. The primary endpoints of interest encompassed overall survival (OS) and progression-free survival (PFS)for postoperative adjuvant therapy, as well as pathological complete response (PCR) following neoadjuvant therapy. Adverse events were considered as secondary outcomes. The statistical analysis was performed using Revman 5.4.1. A total of six studies involving 2348 breast cancer patients were deemed eligible according to the selection criteria. The pooled meta-analysis revealed that there were no statistically significant differences observed in the primary outcomes of overall survival (OS) (HR 1.06, 95% CI 0.88-1.28) and progression-free survival (PFS) (HR 1.10, 95% CI 0.90-1.34) across the four postoperative adjuvant chemotherapy trials, as well as in the two neoadjuvant chemotherapy trials with respect to the primary outcome of pathological complete response (PCR) (OR 1.65, 95% CI 0.93-2.95) when comparing regimens containing anthracycline drugs to those without. In terms of adverse events, the probability of experiencing diarrhea (OR 3.94, P = 0.004) and hand-foot syndrome (OR 10.89, P = 0.004) was significantly higher in the capecitabine group, attributable to the drug characteristics. Conversely, the likelihood of developing neutropenia (OR 0.50, P = 0.03) was higher in the anthracycline group. According to the current evidence, there was no statistically significant difference in the primary outcomes when capecitabine was substituted for anthracycline drugs. Thus, capecitabine can be regarded as a feasible alternative in the subset of patients who necessitate the exclusion of anthracyclines.

Effect of Yoga on Endothelial Function: A Systematic Review and Meta-Analysis.

Introduction: Endothelial dysfunction is the initial step in the pathogenesis of atherosclerosis; and it plays a central role in the development of cardiovascular diseases and many types of human diseases (diabetes, kidney failure, cancer, and viral infections). Strategies that are effective in protecting vascular endothelial function and retard or reversing endothelial dysfunction in the early stage appear to be potential in the prevention of vascular, cardiac, and many human diseases. Several studies have been carried out on the effects of yoga on endothelial function, but the results of these studies have not been synthesized. This study aimed at conducting a systematic review and meta-analysis to determine the effectiveness of yoga on endothelial function. Methods: A systematic review and meta-analysis of studies that assessed the effect of yoga practice on vascular endothelial function was done as per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The PubMed, Scopus, Google Scholar, and Cochrane controlled register of trials (CENTRAL) were searched from inception to August 2022. The search strategy was constructed around yoga-based techniques and endothelial function. All the yoga-based interventional studies on endothelial function or dysfunction were included in this review. A narrative synthesis and descriptive analysis were done due to the diverse methodology of selected studies. We carried out a formal meta-analysis of controlled trials that assessed the effect of yoga on flow-mediated dilatation (FMD), a measure of endothelial function. Results: A total of 18 studies were included for review involving 1043 participants. Yoga training showed improved endothelial function in 12 studies, whereas 6 studies did not find any statistically robust effect. Meta-analysis (n = 395 participants, 6-studies, 7 comparisons) showed an increase in brachial FMD by yoga practice (mean difference = -1.23%; 95% confidence interval -2.23 to -0.23; p = 0.02). The heterogeneity between the studies was 43% (Tau2 = 0.70, χ2 = 10.49). The risk of bias was low to moderate in these studies. No adverse effects were reported. Conclusions: Yoga practice improved endothelial function. Yoga could be a safe and potential integrative medicine to improve endothelial function. However, as the statistical heterogeneity, that is, variation in the FMD among the studies was moderate, large clinical trials are necessary for its clinical recommendations.
