Different Uses of Conscious Sedation for Managing Dental Anxiety During Third-Molar Extraction: Clinical Evidence and State of the Art.

Dental anxiety, linked to avoiding dental treatment and heightened medical and surgical risks, prompted this systematic review. The objective is to synthesize existing evidence on conscious sedation techniques employed for managing dental anxiety in patients scheduled for third molar extraction surgery, aiming to identify optimal approaches and address knowledge gaps. This systematic review followed the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" checklist and the population, investigation, comparation, outcome framework. The protocol still needs to be registered. A thorough search was conducted, incorporating MEDLINE/PubMed, EMBASE, SCOPUS, clinicaltrials.gov, and the Cochrane Database of Systematic Reviews until February 2024. Only randomized controlled trials were considered, following "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines. The risk of bias was evaluated following the Cochrane Handbook for Systematic Reviews of Interventions. Eighteen randomized controlled trials involving 2081 patients were included. Certain factors limited the feasibility of a meaningful meta-analysis, leading to a narrative synthesis. Conscious sedation with virtual reality showed an association with improved dental anxiety in 4 studies. One study reported reduced cortisol levels with midazolam compared with a placebo, whereas another noted significant variations in perioperative renin levels with remifentanil versus placebo. This review reveals inconclusive and conflicting findings regarding the role of conscious sedation in managing dental anxiety during third molar extraction surgery. Persistent uncertainties arise due to a need for consistent, standardized outcome measures. Addressing these limitations in study design is crucial for future research.

Mirabegron 50 mg once daily, long-term treatment maximizes benefit in middle-aged and older people with overactive bladder syndrome: a systematic review and meta-analysis of nine phase II/III, randomized, double-blind, parallel-design, placebo-controlled, multicenter, and multinational trials.

The prevalence and severity of overactive bladder increase with age, and mirabegron is an approved treatment for this condition. This meta-analysis systematically evaluated the efficacy and safety of mirabegron compared with placebo for overactive bladder treatment. We searched PubMed and the Cochrane Library (30 October 2023) for relevant articles (source: MEDLINE, EMBASE, ClinicalTrials.gov, ICTRP, CINAHL). We included randomized controlled trials involving adults with overactive bladder syndrome that compared mirabegron with placebo treatment. Data were analyzed according to the Cochrane Handbook for Systematic Reviews of Interventions [Review Manager (computer program) Version 5.4]. Nine parallel-group trials (10 articles) were included. The evaluation included a total of 8,527 adults, including 6,445 women and 2,082 men, of whom 5,726 were White, 2,462 were Asian, and 161 were Black. The mean age of the participants ranged from 53.4 to 60.3 years. This evaluation involved three specifications of mirabegron: 25 mg, 50 mg, and 100 mg. In all trials, patients were enrolled in a 12-week double-blind treatment period, and the dose was once daily. The review of trials found that on average, people taking mirabegron had about 13 ml more volume voided per micturition, five fewer micturitions, and four fewer incontinence episodes every week, with moderate improvements in quality of life. About one in five people taking the drug reported TRAEs. Mirabegron treatment is well tolerated, with the risk of adverse events similar to that of a placebo. For best results, a dose of 50 mg once daily is recommended for long-term use. It is unclear whether any benefits are sustained after treatment discontinuation.

Evaluation of ocular and systemic endpoints after radiation of posterior uveal melanoma – A systematic review and meta-analysis

BackgroundDue to the large number of radiotherapeutic options for treatment of posterior uveal melanoma (UM), advantages of each option regarding important clinical endpoints have yet to be determined. Therefore, objective of this systematic review was to analyze the numerous pro- and retrospective cohort studies focusing on the efficacy of different radiotherapeutic options for UM in adults, considering local tumor control, overall survival, visual acuity, eye preservation, metastasis, radiation side effects and dose rates. MethodsThe Review was performed based on the Cochrane Handbook of Systematic Reviews. The PubMed database was searched for studies published from January 1st, 2000, up to December 31st, 2021. Research, study selection and critical appraisal was performed by two reviewers. The risk of bias assessment was performed through the revised Cochrane risk of bias tools RoB 2 and ROBINS-I. A meta-analysis of proportions was performed using R (R version 4.1.3, library: meta, procedure: metaprop). This systematic review was registered with Prospero (ID CRD42022311758). ResultsOf 4886 studies identified in the database, a total of 20 studies with 4979 participants were included in the qualitative synthesis. Through critical appraisal with ROBINS-I and RoB 2, studies received a ‘moderate’, ‘serious’ or ‘some concerns’ overall risk of bias. Heterogeneity analysis allowed for meta-analysis of proportion of 3 outcome-therapy combinations: local tumor control with I-125 Brachytherapy (proportion: 0.94, CI 95 %: 0.91–0.98), local tumor control with proton therapy (proportion: 0.96, CI 95 %: 0.92–1.00) and eye preservation with I-125 brachytherapy (proportion: 0.91, CI 95 %: 0.88–0.93). This shows local tumor control to be at 94 % with I-125 brachytherapy and at 96 % with proton therapy, as well as an eye preservation rate of 91 % with I-125 brachytherapy. DiscussionThe evaluation of outcomes of radiotherapy in UM is limited because of missing data on radiation doses as well as great heterogeneity of study protocols. Radiation therapy outcomes are so far not comparable. Therefore, we recommend for upcoming studies on this topic to provide the biological effective dose (BED) or the equivalent dose in 2 Gy fractions (EQD2) per eye structure, thereby enabling a comparison of outcomes of different forms of radiation therapy.

Immune Checkpoint Inhibitor–Induced Cardiotoxicity

Immune checkpoint inhibitors (ICIs) improve outcomes in a wide range of cancers; however, serious adverse effects, including cardiovascular adverse effects (CVAEs), can occur. To determine the incidence of CVAEs and analyze data on the management of myocarditis in patients exposed to ICIs. PubMed, Embase, and Cochrane Central Register of Controlled Trials from inception were searched on April 4, 2023. Two separate studies were performed. Key inclusion criteria for study 1 were phases 1 to 4 trials involving adults with malignant neoplasms treated with an ICI and toxicity data; for study 2, publications (case reports and retrospective analyses) on clinical manifestations and treatment of patients with ICI-induced CVAEs. Studies with dose escalation or fewer than 11 patients in each group and all case reports, retrospective analyses, letters, reviews, and editorials were excluded from study 1. Studies not published in English were excluded from study 2. The PRISMA guidelines and Cochrane Handbook for Systematic Reviews were followed. Data were extracted independently by 2 researchers. A meta-analysis of the incidence of CVAEs in clinical trials and a systematic review of the evidence for the management of myocarditis were performed. Data were pooled using a random-effects model. In study 1, the primary outcome was incidence CVAEs in clinical trials with ICIs and ICI combination therapies. Study 2 examined evidence supporting specific management strategies that may decrease the mortality rate of myocarditis. The primary outcomes were planned before data collection began. In study 1, a total of 83 315 unique participants in 589 unique trials were included in the meta-analysis. Incidence of CVAEs induced by anti-programmed cell death 1 and/or programmed cell death ligand 1 was 0.80% (95% CI, 0%-1.66%) in clinical trials, with no differences between the compounds, except for cemiplimab, which was associated with a higher risk of CVAEs. Incidence of CVAEs following ipilimumab treatment was 1.07% (95% CI, 0%-2.58%). The incidence of myocarditis was significantly higher following treatment with dual ICIs. However, CVAE incidence was not higher with dual ICIs, ICI combination with chemotherapy, or tyrosine kinase inhibitors. Evidence from randomized clinical trials on recommended monitoring and treatment strategies for ICI-induced myocarditis was lacking. Study 2 showed that myocarditis-associated mortality occurred in 83 of 220 patients (37.7%). Prospective data from 40 patients with myocarditis indicated that systematic screening for respiratory muscle involvement, coupled with active ventilation, prompt use of abatacept, and the addition of ruxolitinib, may decrease the mortality rate. Immune checkpoint inhibitor-induced CVAEs and/or myocarditis were recorded in 1.07% of patients in clinical trials. The CVAE mortality risk remains high, justifying the need for monitoring and management strategies for which evidence from randomized clinical trials is absent. Early recognition, ICI therapy cessation, prompt initiation of corticosteroid therapy, and escalation of therapy are all crucial elements for achieving optimal outcomes. Prospective clinical trials or at least prospective registration of treatments and outcomes are highly warranted.

Effect of low-intensity pulsed ultrasound on postoperative rehabilitation of rotator cuff tears: Protocol for a systematic review and meta-analysis.

Rotator cuff tears are a common shoulder injury that significantly impacts patients' daily lives and work abilities. Although surgical treatment methods for rotator cuff tears have been continuously improved with advances in medical technology, postoperative rehabilitation remains challenging. Therefore, finding effective rehabilitation treatments is crucial for improving patient prognosis and enhancing quality of life. This study will aim to systematically evaluate the impact of low-intensity pulsed ultrasound (LIPUS) on postoperative rehabilitation of rotator cuff tears, comprehensively assessing the efficacy and safety of LIPUS in postoperative recovery. This protocol will search multiple databases including PubMed/MEDLINE, Embase, Cochrane Library, CNKI, Scopus, and Web of Science to identify randomized controlled trials related to LIPUS for postoperative rehabilitation of rotator cuff tears. The search will encompass literature published from the inception of the databases up to April 2024. Methodological quality assessment and data extraction will be conducted using the Cochrane Handbook for Systematic Reviews of Interventions and PRISMA guidelines. Meta-analysis will be performed on appropriate studies using either random-effects or fixed-effects models, and subgroup analyses will be conducted to explore potential heterogeneity. Studies meeting the inclusion criteria will be included in the analysis. All analyses will be performed using Stata version 16.0. The incidence of rotator cuff tear rates will be assessed by imaging techniques such as MRI or ultrasound. Pain intensity will be scored using standardized pain assessment scales, such as the Visual Analog Scale (VAS). Improved range of motion (ROM) in shoulder flexion, abduction, and rotation. Functional outcomes will be evaluated using effective measures such as Constant-Murley scores (CMS) and shoulder joint scores by American Shoulder and Elbow Surgeons (ASES). Adverse events associated with LIPUS therapy, including skin irritation, increased pain, or any other complications. Subgroup analysis will also be carried out if possible. Following the meta-analysis, we will assess the overall effect of LIPUS on postoperative rehabilitation of rotator cuff tears, and further explore its impact on aspects such as pain relief, functional improvement, and postoperative complications. It is anticipated that this study will provide comprehensive evidence regarding the role of LIPUS in postoperative rehabilitation of rotator cuff tears, guiding clinical practice and future research. The resultant manuscript will be submitted for publication in a peer-reviewed journal. CRD42024530798.

Engagement With Conversational Agent-Enabled Interventions in Cardiometabolic Disease Management: Protocol for a Systematic Review.

Cardiometabolic diseases (CMDs) are a group of interrelated conditions, including heart failure and diabetes, that increase the risk of cardiovascular and metabolic complications. The rising number of Australians with CMDs has necessitated new strategies for those managing these conditions, such as digital health interventions. The effectiveness of digital health interventions in supporting people with CMDs is dependent on the extent to which users engage with the tools. Augmenting digital health interventions with conversational agents, technologies that interact with people using natural language, may enhance engagement because of their human-like attributes. To date, no systematic review has compiled evidence on how design features influence the engagement of conversational agent-enabled interventions supporting people with CMDs. This review seeks to address this gap, thereby guiding developers in creating more engaging and effective tools for CMD management. The aim of this systematic review is to synthesize evidence pertaining to conversational agent-enabled intervention design features and their impacts on the engagement of people managing CMD. The review is conducted in accordance with the Cochrane Handbook for Systematic Reviews of Interventions and reported in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Searches will be conducted in the Ovid (Medline), Web of Science, and Scopus databases, which will be run again prior to manuscript submission. Inclusion criteria will consist of primary research studies reporting on conversational agent-enabled interventions, including measures of engagement, in adults with CMD. Data extraction will seek to capture the perspectives of people with CMD on the use of conversational agent-enabled interventions. Joanna Briggs Institute critical appraisal tools will be used to evaluate the overall quality of evidence collected. This review was initiated in May 2023 and was registered with the International Prospective Register of Systematic Reviews (PROSPERO) in June 2023, prior to title and abstract screening. Full-text screening of articles was completed in July 2023 and data extraction began August 2023. Final searches were conducted in April 2024 prior to finalizing the review and the manuscript was submitted for peer review in July 2024. This review will synthesize diverse observations pertaining to conversational agent-enabled intervention design features and their impacts on engagement among people with CMDs. These observations can be used to guide the development of more engaging conversational agent-enabled interventions, thereby increasing the likelihood of regular intervention use and improved CMD health outcomes. Additionally, this review will identify gaps in the literature in terms of how engagement is reported, thereby highlighting areas for future exploration and supporting researchers in advancing the understanding of conversational agent-enabled interventions.

The effectiveness of different attentional foci on the acquisition of sport-specific motor skills in healthy adults: a systematic review with network meta-analysis.

The acquisition of motor skills is a key element in many sports. A motor learning principle, which is frequently used to support skill acquisition is the application of different attentional foci. The effectiveness of different attentional foci on performance and the learning of motor skills has been investigated in various sports using randomised controlled trials. The aim of the present study was to investigate the effectiveness of different attentional foci (such as external (EFA) and internal attentional foci (IFA), but also holistic and switching foci) on the performance and learning of a sport-specific motor task in healthy individuals. This study was a systematic review with network meta-analysis. We followed the Prisma reporting guideline and the Cochrane handbook for systematic reviews. Cinahl, Embase, Medline and Cochrane Central were searched for eligible studies. Network meta-analyses were performed for the post-acquisition, retention and transfer test endpoints. Twelve studies were included in the review. At post-acquisition an EFA was the most effective intervention compared to the control intervention (SMD: 0.9855; 95% CI [0.4-1.57]; p: 0.001). At the retention and transfer test endpoints, a holistic focus of attention had the highest effectiveness compared to an IFA (SMD 0.75; 95% CI [-0.1 to 1.6]; p: 0.09) and (SMD 1.16; 95% CI [0.47-1.86]; p: 0.001). For all three endpoints, we analysed a greater effectiveness of an EFA and holistic focus compared to an IFA. Several promising different attentional focus interventions were identified. The largest effects were analysed for a holistic focus. However, only one study used this intervention and therefore there remains uncertainty about the effectiveness. With regard to the inconsistency observed, the analysis at post-acquisition should be interpreted with caution. Modified versions of the EFA were the imagined and the dynamic EFA. Both were only explored in single studies and should therefore be investigated in further follow-up studies that directly compare them.

Recombinant erythropoietin for the treatment of iron deficiency anemia in pregnancy: A systematic review.

Treatment options for severe, refractory iron deficiency anemia are limited in pregnancy. To review the available literature on the use of recombinant erythropoietin in the treatment of iron deficiency anemia in pregnancy. An electronic search of seven databases from inception to March 2022 was performed using a combination of keywords. We included all randomized controlled or observational studies of pregnant patients with iron deficiency anemia who received recombinant erythropoietin or control. The primary outcome was a change in hematologic parameters (hemoglobin or hematocrit) after treatment. Studies were appraised using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. Data were summarized using narrative synthesis and descriptive statistics as appropriate. This study was registered with PROSPERO, CRD42022313328. Of 234 studies screened, five studies met the inclusion criteria and had sufficient data for analysis (n = 103 recombinant erythropoietin and n = 104 controls). All patients in the intervention group received iron supplementation (intravenous or oral) in addition to recombinant erythropoietin. All patients in the control group received iron supplementation (intravenous or oral) alone. As the result of variance between studies in inclusion criteria, the timing of repeat blood draws, and data reporting, a meta-analysis could not be performed. Three studies found that serial recombinant erythropoietin combined with iron supplementation was more effective at raising hematologic laboratory parameters (hemoglobin or hematocrit) than iron alone. One study reported no difference in hemoglobin or hematocrit levels between groups at day 28. However, patients in this study only received one dose of recombinant erythropoietin, whereas those in the other studies received serial doses. Another study also found no difference in hemoglobin levels by day 28, but patients in the recombinant erythropoietin group had lower hemoglobin levels at baseline and a more rapid rise in hemoglobin than iron alone. This is demonstrated by a more significant rise in hemoglobin at day 11 in the recombinant erythropoietin group than in the control group. Serial recombinant erythropoietin administration and iron supplementation may be more effective at treating refractory iron deficiency anemia in pregnancy than iron supplementation alone.

Do Adductor Tenotomies Prevent Progressive Migration in Children with Cerebral Palsy?: A Systematic Review.

Up to one-third of children with cerebral palsy (CP) develop migration of the hip, and the risk increases with a higher Gross Motor Function Classification System (GMFCS). In progressive hip migration in young children, adductor tenotomy is an accepted treatment option to delay or prevent progressive hip migration. However, there is quite a large variability in reported results. This systematic review aims to determine the effectiveness of a soft-tissue release in the prevention of progressive hip migration in children with CP. This systematic review was performed in accordance with the guidelines of the Cochrane Handbook for Systematic Reviews and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statements. Our inclusion criteria were studies describing pediatric, skeletally immature patients with CP and a "hip at risk" of progressive hip migration. Exclusion criteria were simultaneous bony reconstructions, case reports, technical notes, published abstracts, or studies with a follow-up under 1 year postoperatively. The primary outcomes were defined as failure rate (progressive hip migration and/or need for bony surgery, as defined by each paper) and change in migration percentage (MP) at final follow-up. As secondary analyses, we evaluated the outcome after specific subtypes of surgeries and assessed whether performing lengthening of iliopsoas, neurectomy of the anterior branch of the obturator nerve, age at the time of surgery, GMFCS level, and postoperative management impact the outcome. Our literature search identified 380 titles. Eighty-four articles underwent full-text review, of which 27 met our inclusion/exclusion criteria and were subsequently selected for quantitative analysis. A prevalence meta-analysis was performed including 17 studies (2,213 hips). Mean follow-up ranged from 12 to 148.8 months. The mean preoperative MP was 33.4% (2,740 hips) and 29.9% at follow-up. The overall reported failure rate was 39% (95% confidence interval, 26%-52%). Performing a release of only adductor longus had a failure rate of 87%, whereas more extensive soft-tissue releases showed significantly better results with failure rates ranging from 0 to 44% (p < 0.001). Lengthening of the iliopsoas had no significant impact on failure rate (p = 0.48), nor did performing an obturator neurectomy (p = 0.92). The failure rate of adductor tenotomies to prevent progressive hip migration appears to be as high as 39% in studies with a varying follow-up. The failure rates are significantly higher when isolated release of the adductor longus is performed. This systematic review supports clinical decision making in children with CP and early hip migration. Level IIA. See Instructions for Authors for a complete description of levels of evidence.

Effects of the combination of red yeast rice-containing commercial Chinese polyherbal preparation with statins for dyslipidemia: a systematic review and meta-analysis.

Significant challenges are associated with the pharmacological management of dyslipidemia, an important risk factor for cardiovascular disease. Limited reliable evidence exists regarding the efficacy of red yeast rice (RYR)-containing commercial Chinese polyherbal preparation (CCPP), despite their widespread use in China. We aimed to investigate the efficacy of RYR-containing CCPPs combined with statins in treating dyslipidemia. Eight databases were searched for relevant randomized controlled trials (RCTs) from database inception date to November 2023. Outcome measures, including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglyceride (TG), clinical efficacy, and adverse reactions, were assessed. The Cochrane Handbook for Systematic Reviews of Interventions was used for quality evaluation, and the meta-analysis was conducted using RevMan 5.3 and Stata 15.1. Thirty-three studies involving 4,098 participants were included. The combination of RYR-containing CCPP, such as Xuezhikang (XZK), Zhibitai (ZBTAI), or Zhibituo (ZBTUO) with statins had a significant effect on the increase in clinical efficacy [RR:1.16, 95%CI (1.13, 1.19), p < 0.00001]. In addition, they also improved blood lipid profile parameters by increasing HDL-C levels [MD:0.21, 95%CI(0.17, 0.25), p < 0.00001], and decreasing TC [MD: 0.60, 95%CI(-0.76, -0.45), p < 0.00001], TG [MD: 0.33, 95%CI(-0.39, -0.26), p < 0.00001] and LDL-C levels [MD: 0.45, 95%CI(-0.54, -0.36), p < 0.00001]. No significant adverse reactions was observed in the RYR-containing CCPPs. Notably, ZBTAI and XZK significantly reduced the incidence of gastrointestinal disturbances and muscular adverse reactions. However, subgroup analyses suggested that the type of CCPPs, dose, and treatment duration might affect the efficacy of RYR-containing CCPPs. RYR-containing CCPPs combined with statins appears to improve lipid profiles and clinical efficacy in patients with dyslipidemia. However, due to the poor quality of the included studies, and some studied showing negative findings was unpublished. The results should be interpreted with caution until further confirmation by well-designed RCTs. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=487402, identifier CRD42023487402.

A rapid review of the barriers and facilitators of mental health service access among Veterans and their families.

Transitioning to civilian life after military service can be challenging for both Veterans and their families. Accessible mental health services are crucial during this period to provide support. The objective of this review was to conduct a rapid review to capture the barriers and identify facilitators that influence access to mental health services for Veterans and their families during the post-service transition period. This review was conducted using the Cochrane Handbook for Systematic Reviews of Interventions as a methodological framework and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Rapid Review (PRISMA-RR). A total of 60 articles and 67 independent samples were included in the final data analyses. Across the included articles, this review identified 23 barriers and 14 facilitator themes. Issues navigating the mental health care system was identified as the main challenge among Veterans and their families, and those who received support navigating the system identified this as a significant facilitator. Applying the Theoretical Domains Framework, most of the identified barriers and facilitators were categorized into environmental context and resources domain. The heterogeneity in Veterans' and Veteran families' experiences with mental health care-seeking may suggest that access to mental health care for Veterans and Veteran families cannot be solved by addressing one type of barrier alone. Instead, coordinated efforts to address prioritized systemic, logistical, social, and inter-/intrapersonal obstacles are essential for improving access and optimizing mental health care outcomes. These insights underscore the complexity of considerations for Veterans and families accessing mental health care.

Hamstring autografts demonstrate either similar or inferior outcomes to quadriceps or bone-patellar tendon-bone autografts in revision anterior cruciate ligament reconstruction: A systematic review of comparative studies.

To evaluate the clinical outcomes in patients undergoing revision anterior cruciate ligament reconstruction (r-ACLR) using hamstring tendon (HT) autografts with those using either quadriceps tendon (QT) or bone-patellar tendon-bone (BPTB) autografts or allografts. Three databases were searched on 8 August 2023. The authors adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Revised Assessment of Multiple Systematic Reviews (R-AMSTAR) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, surgical details, patient-reported outcome measures (PROMs), rates of instability, failure and return to sport (RTS) were extracted. Eleven studies comprising 859 patients were included in this review. Five studies compared HT and QT autografts. One study each reported greater IKDC scores (p = 0.04) and Tegner scores (p = 0.04) in the QT group, while one study each reported higher anterior translation (p = 0.04), rates of positive pivot shift (p = 0.03) and rates of failure (p = 0.03) in the HT group. Six studies compared HT and BPTB autografts with one study each reporting greater Lysholm scores (p = 0.02) and less side-to-side anterior laxity (p < 0.01) in the BPTB group. Two studies compared HT autografts with allografts with only one study reporting a faster time to RTS in the HT group than the allograft group (p < 0.001). All other comparisons were not significant. HT autografts result in either similar or inferior outcomes in r-ACLR when compared to QT or BPTB autograft options. Allografts resulted in similar outcomes to HT autografts apart from greater time to RTS for r-ACLR. Level III.

Evidence for Intermittent Theta Burst Transcranial Magnetic Stimulation for Dysphagia after Stroke: A Systematic Review and Meta-analysis.

Dysphagia is the most common serious complication after stroke, with an incidence of about 37-78%, which seriously affects the independence of patients in daily life and clinical recovery. Repetitive transcranial magnetic stimulation (rTMS), as a non-invasive neuromodulation technique, is an emerging option for post-stroke dysphagia. Theta burst stimulation (TBS) is a new mode of transcranial magnetic stimulation that simulates the frequency of pulses released in the hippocampus.Intermittent theta burst stimulation (iTBS) has been shown to increase cortical excitability and improve swallowing function in patients. Our study sought to summarize existing clinical randomized controlled trials to provide evidence-based medical evidence for the clinical use of iTBS. A computer search was conducted on 4 Chinese (Chinese Biomedical Literature Database, VIP Information Resource System, CNKI, and Wanfang Medical Science) and 4 English (including Cochrane Library, Embase, PubMed, Web of Science) databases to retrieve all randomized controlled trials in Chinese and English that explored the effects of Intermittent Theta Burst Stimulation for post-stroke dysphagia. The retrieval years are from database construction to 23 November 2023. The primary outcome measure was a change in Penetration/Aspiration Scale (PAS), Standardized Swallowing Assessment (SSA) and Functional Oral Intake Scale (FOIS), Secondary outcomes included Fiberoptic Endoscopic Dysphagia Severity Scale (FEDSS), water-swallowing test (WST) etc. A meta-analysis by Standardized Mean Difference (SMD) and 95% confidence interval (CI) was performed with RevMan 5.3. we appraise risk of bias(RoB) of each study with the Cochrane RoB tool. Detailed instructions for using the Cochrane RoB tool are provided in the Cochrane Handbook for Systematic Reviews of Interventions (The Cochrane Handbook). Nine studies were obtained from eight databases after screening by inclusion and exclusion criteria, 567 patients from 9 studies were included in the meta-analysis, and one study was included in the qualitative analysis due to different control groups. Two of the nine studies had an unclear risk of bias, and four studies were at low risk. The results showed that iTBS significantly improved SSA, PAS, FOIS, and PAS scores in stroke patients compared to the control group(P < 0.05), and promoted swallowing function recovery. Our systematic review provides the first evidence of the efficacy of iTBS in improving dysphagia in stroke patients. However, the number of available studies limits the persuasiveness of the evidence and further validation by additional randomized controlled trials is needed.

The effect of telemedicine interventions on patients with diabetic foot ulcers: A systematic review and meta-analysis of randomized controlled trials.

The meta-analysis was performed to evaluate the effectiveness of telemedicine interventions on patients with diabetic foot ulcers(DFU). The authors conducted a comprehensive search across eight databases. The aim was to identify randomized controlled trials examining the effectiveness of telemedicine for patients with DFU. Methodological qualities of included studies were assessed using Cochrane Handbook for Systematic Reviews of Intervention.. Subsequently, a meta-analysis was conducted using RevMan 5.3 to synthesize the findings. Ten studies involving 1678 patients with DFU were included in the meta-analysis. In comparison to the face-to-face intervention group, telemedicine interventions significantly reduced the amputation rate (risk ratio (RR) = 0.64, 95% confidence interval (CI) = 0.44－0.92, p = 0.02), decreased costs (mean difference (MD) = -4158.51, 95% CI = -7304.69－-1012.34, p = 0.01), better controlled fasting blood glucose( FPG)(MD = -0.89, 95% CI = -1.43－-0.36, p = 0.001), achieved superior glycated hemoglobin(HbA1c) control (MD = -0.71, 95% CI = -1.01－-0.41, p ˂ 0.00001). No significant differences were observed between the telemedicine group and the face-to-face group in terms of healing rate, mortality, and healing time. Innovations: Our study suggests that telemedicine is a viable strategy for managing DFU. The meta-analysis indicates that telemedicine interventions have a positive effect on DFU. Nevertheless, more well-designed and high-quality studies are needed to reach a conclusion with greater confidence.

Complications following surgical treatment of patella fractures - a systematic review and proportional meta-analysis.

The aim of this systematic review and proportional meta-analysis was to identify complications of surgical treatment of patella fractures and to estimate their incidence. We extended existing knowledge on this topic by including several more recent and large-scale studies. This systematic review and meta-analysis were performed in accordance with the Cochrane Handbook for systematic reviews of interventions. After searching in PubMed, MEDLINE, EMBASE, Cochrane Library, and OpenGrey, all studies after 2000, with study populations > 100 patients, including only patients > 18 years and follow-up > 30 days, were included. Two independent authors assessed the literature search and extracted the data. The risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Scale. The meta-analysis was performed on complications pooled in infections, nonunion, symptomatic implant removal, and fixation failure. The data on complications were available from 14 studies, including a pool of 5659 patients. The most common complication was symptomatic implant removal, affecting. Surgically, treatment of patella fractures was associated with a high risk of complications. The most common complication was symptomatic implant removal, affecting 29.6% of patients. Other complications stated were fixation failure 5.2%, infections 3.1% and nonunion 1.7%.

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.

Effect of Corona Virus on Olfactory &amp; Gustatory Functions (Systematic Review Study)

Abstract Background Because of the rapid spreading of severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) infection, the Coronavirus disease 2019 (COVID-19) outbreak was characterized as a pandemic by the WHO on March 11, 2020. Materials and Methods Following the PRISMA statement guidelines, we conducted this systematic review and meta-analysis according to the Cochrane handbook of systematic reviews of intervention. We searched PubMed, Scopus, Cochrane, and Web of Science, Embase, and Science Direct till December 2021 with relevant keywords. We included the whole clinical studies assessing olfactory and/or gustatory dysfunctions (OGD) in patients with COVID-19, studies including patients with a confirmed diagnosis of COVID-19 by a positive result of RT-PCR were included, studies that assessed the OGD by either subjective evaluation were also included, studies written in English languages only, all of the studies must have been written in English as a full-text manuscript, double or single-arm designs. Results A total of 12 studies were finally included for the final qualitative and quantitative analysis illustrating the association and the relationship between COVID-19 infection and olfactory and gustatory functions. The mean age of the participants was 49.12 years. The pooled analysis of the included studies showed a significant association of positive results between OGD and COVID-19 infection. Also, the analysis showed a significant association of positive results between either isolated olfactory or gustatory dysfunction and COVID-19 infection. Regarding the association between gustatory dysfunction in COVID-19 patients versus (Acute respiratory infection) ARI patients with no detectable virus, the analysis showed a significant difference between COVID-19 patients and ARI patients with no detectable virus regarding the gustatory dysfunction meaning there is a high association between gustatory dysfunction and COVID-19 patients other than ARI patients with no detectable virus. Finally, the pooled analysis of the included studies showed a significant difference between COVID-19 patients and ARI patients with other respiratory viruses (ORV) in terms of OGD. Conclusion Based on the available evidence, there are regional and chronological differences in the prevalence rates of olfactory and gustatory dysfunction. Future studies, particularly those that document the temporal relationship in the onset of these 2 symptoms, are needed.

Use of Drains in Spine Surgery Systematic Review &amp; Meta-Analysis

Abstract Background Wound suction drains have been used to decrease the rate of postoperative hematoma formation and thus wound infections for many years throughout all surgical subspecialties. Although the use of surgical drains dates back to the years of Hippocrates, in the orthopedic literature these drains have not been shown to be beneficial in decreasing the rates of these complications, especially in orthopedic procedures including fracture fixation or arthroplasty surgeries. However, these drains are still commonly used throughout the orthopedic community, including spine surgery. Aim of the Work This study aims to review the use of closed suction drains in spine surgery. It aims to perform a systematic review and meta-analysis of the outcome of use of drains, their method and provide intervention recommendation by the best available evidence. Material and Methods We followed the PRISMA statement guideline during this systematic review and meta-analysis preparation and performed all steps according to the Cochrane handbook of systematic reviews of intervention. We searched PubMed, Scopus, Cochrane Central Register of Controlled Trials, Web of Science, Embase, and Science Direct till September 2021 relevant keywords. We used the following search strategy for searching different databases. “Wound drain” OR “Suction drainage” OR “Drain” OR “Spine Surgery” OR “Spine” OR “SSI” OR “Surgical Site Infection” OR “Hematoma”) AND (“Vertebral Column” OR “Column, Vertebral” OR “Columns, Vertebral” OR “Vertebral Columns” OR “Spinal Column” OR “Column, Spinal” OR “Columns, Spinal” OR “Spinal Columns” OR Vertebra OR Vertebrae). All the references of the included studies were searched for relevant studies. Results In contrast to other spine procedures, posterior spinal fusion as a surgical treatment for adolescent idiopathic scoliosis necessitates big skin incisions, a lengthy operating duration, and a higher rate of blood transfusion. This meta-analysis comprised four studies. Surprisingly, drains had no effect on total blood loss, the rate of post-surgical infection, the rate of post-operation hematoma, or hospital stay. The drain group required greater blood transfusion than the non-drain group, according to. A drain could also result in a post-durotomy fistula. Drain use is not required after intra-dural spinal cord tumor surgery. Regarding the difference in hemoglobin between preoperative and day 3 postoperative 3 studies, no difference was found between the drain group and the no drain group in all spine surgeries. Conclusion The routine use of a drain in post-operative spine surgery appears to have no effect on the likelihood of post-operative surgical site infections or post-operative epidural hematoma, according to this study. It does, however, increase total estimated blood loss without lowering hemoglobin levels, and has no effect on hospital stay length. To further strengthen any meta- analysis in the future, high-quality studies addressing their use in the spine are require.

Incidence of Recurrence Post Hemi Thyroidectomy in Thyroid Papillary Carcinoma: A Meta-Analysis

Abstract Background Papillary thyroid carcinoma (PTC) is the most common subtype of thyroid carcinoma. It has an excellent prognosis, with a 10-year survival rate of more than 95 per cent, although outcome is poorer for aggressive subtypes. Aim of the Work Our work in this study shows that the incidence of recurrence post hemi thyroidectomy is significantly higher compared to post total thyroidectomy and in case of multifocal and insular carcinoma with hemi thyroidectomy it increases the incidence of recurrence and drastically affecting the 10-year survival rate and the quality of life. Material and Methods We followed the PRISMA statement guideline during this systematic review and meta-analysis preparation and performed all steps according to the Cochrane handbook of systematic reviews of intervention. We searched PubMed, Scopus, Cochrane Central Register of Controlled Trials, Web of Science, Embase, and Science Direct till November 2021 relevant keywords. We used the following search strategy for searching different databases: (“Papillary Thyroid Cancer” OR “Papillary Thyroid Cancers” OR “Papillary Thyroid Carcinomas” OR “Papillary Carcinoma Of Thyroid” OR “Papillary Thyroid Carcinoma” OR “Familial Non medullary Thyroid Cancer” OR “Non medullary Thyroid Carcinoma” OR “Non medullary Thyroid Carcinomas” OR “Thyroid Carcinoma, Non medullary” OR “Thyroid Carcinomas, Non medullary”) AND (Hemithyroidectomy OR Thyroidectomy OR Thyroidectomies OR thyroid removal). All the references of the included studies were searched for relevant studies. Results Multifocality and insular carcinoma and bilaterality increase the incidence of recurrence drastically so it is recommended for total thyroidectomy. Gender plays a role in the aggressiveness of the tumor but not in the incidence of recurrence as this is determined by the selection criteria of the candidate and the surgical technique. We studied 7 risk factors through this meta-analysis and it is recommended for application of LNR as a post op prognostic tool for recurrence and to apply hemi thyroidectomy for tumor size &amp;lt;2 cm instead of &amp;lt; 4 also meticulous pre-operative workup, accurate risk assessment, stratification and staging this is to customize a road map for every patient through a multi-disciplinary team. Conclusion In this meta-analysis we found that in low grade differentiated papillary thyroid carcinoma the recurrence is higher with hemithyroidectomy than in total thyroidectomy after applying the ATA guidelines for 10 years retrospectively but in case of 10 year survival it showed no significant difference.

The Lateral Sinus Tarsi Approach in Fixation of Displaced Intra-Articular Calcaneal Fracture. A Systematic Review &amp; Meta Analysis

Abstract Background Minimally invasive reduction and fixation techniques via a sinus tarsi approach (STA) have been developed in an attempt to avoid the potential complications associated with an extensile lateral approach (ELA) and to be less invasive. Objective Minimally invasive approach including sinus tarsi approach (STA) in displaced intra articular calcaneal fracture displaced intra-articular calcaneal fractures (DIACF) with reference to: Change from baseline in calcaneal height, change from baseline in calcaneal width, change from baseline in calcaneal length, change from baseline in Bohler angle, change from baseline in Gissane angle. Methodology This meta-analysis was carried out in accordance with the Cochrane Handbook of Systematic Reviews of Intervention and Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to answer the question of minimal invasive of lateral sinus tarsi in displaced intra articular calcaneal fracture. The study protocol was registered into the International Prospective Register of Systematic Reviews on September 09, 2020 with a registration number (PROSPERO: CRD42022359197). Results Running our search strategy on PubMed 69 studies, and the Cochrane library resulting in 221 studies and trials. We discarded 12 studies after screening the title and Abstract. Then we screened 18 studies to assess their eligibility for inclusion; and in last 10 years. The total sample size for this meta-analysis was 12 participants. 484 patients who completed STA surgery and 514 patients completed ELA surgery. Data Sources Medline databases (PubMed, cochrane) and all materials available in the Internet till 2023. Conclusion In conclusion, using the minimally invasive sinus tarsi approach (STA) is associated with a significant change in calcaneal height and Gissane angle when compared to extended lateral approach (ELA) when used to manage the displaced intra-articular calcaneal fractures (DIACF).
