Effectiveness of glutamine for the treatment of radiodermatitis in cancer patients: a meta-analysis of randomized controlled trials.

BACKGROUND: After receiving radiation therapy, 60%-95% of patients with cancer develop radiodermatitis, which causes pain, wound infection, and poor quality of life. Glutamine is a popular nutritional supplement for patients with cancer. Several studies examined the usefulness of glutamine for reducing radiodermatitis. However, there is still no consolidated evidence for clinical use. METHODS: We searched PubMed, Embase, Cochrane Library, CINAHL PLUS, and the China Knowledge Resource Integrated Database for the relevant literature published up to March 2023, without language restrictions. Two reviewers screened, filtered, and appraised these articles independently, and their data were pooled using a random-effects model. RESULTS: Five randomized controlled trials (RCTs) with 218 participants were analyzed. The incidence of radiodermatitis in the glutamine group (89/110) was significantly lower than in the placebo group (99/108; risk ratio [RR], 0.90; 95% CI, 0.81-1.00; p = 0.05; I2 = 7%). The incidence of moderate to severe radiodermatitis was significantly lower in the glutamine group than in the placebo group (RR, 0.49; 95% CI, 0.32-0.76; p = 0.001; I2 = 52%). Moreover, subgroup analysis demonstrated heterogeneity (I2 = 52%) for moderate to severe radiodermatitis, the risk of which might be significantly reduced by a glutamine dose of 20-30 g/day (RR, 0.60; 95% CI, 0.41-0.87; I2 = 0%). CONCLUSION: The meta-analysis indicate that glutamine might lead to a lower incidence of radiodermatitis, and that a glutamine dose of 20-30 g/day might decrease the incidence of moderate to severe dermatitis. Thus, the serious impact of radiodermatitis on treatment follow-up makes the clinical use of glutamine even more important. PROSPERO number: CRD42021254394.

Perioperative Dexmedetomidine Infusion Improves Perioperative Care of Bariatric-Metabolic Surgery: A Single Center Experience with Meta-Analysis.

PURPOSE: This study aims to determine the effects of perioperative dexmedetomidine infusion (PDI) on Asian patients undergoing bariatric-metabolic surgery (BMS), focusing on the need for pain medications and management of postoperative nausea and vomiting (PONV), and to investigate the association with these variables, including patients' characteristics and BMS data. MATERIALS AND METHODS: A retrospective review of prospectively collected data was conducted in an Asian weight management center from August 2016 to October 2021. A total of 147 native patients with severe obesity were enrolled. All patients were informed of the full support of perioperative pain medications for BMS. The pain numeric rating scale scores, events of PONV, needs for pain medications, and the associated patients' characteristics were analyzed. A p-value of < 0.05 was considered statistically significant. Furthermore, to verify the effects of perioperative usage of dexmedetomidine for BMS, a systematic review with meta-analysis of currently available randomized control trials was performed. RESULTS: Among the 147 enrolled patients, 107 underwent laparoscopic sleeve gastrectomy and 40 underwent laparoscopic Roux-en-Y gastric bypass. PDI has been used as an adjunct multimodal analgesia for BMS in our institution since June 2017 (group D; n = 114). In comparison with those not administered with perioperative dexmedetomidine (group C; n = 33), lower pain numeric rating scale scores (2.52 ± 2.46 vs. 4.27 ± 2.95, p = 0.007) in the postanesthesia care unit, fewer PONV (32.46% vs. 51.52%; p = 0.046), and infrequent needs of additional pain medications (19.47% vs. 45.45%; p = 0.003) were observed in group D. Multivariable analysis demonstrated that type II diabetes mellitus was correlated with the decreased need of pain medications other than PDI (p = 0.035). Moreover, dexmedetomidine seemed to have a better analgesic effect for patients with longer surgical time based on our meta-analysis. CONCLUSION: Based on our limited experience, PDI could be a practical solution to alleviate pain and PONV in Asian patients undergoing BMS. Moreover, it might reduce the need for rescue painkillers with better postoperative pain management for patients with type II diabetes mellitus or longer surgical time.

Maintenance therapy for chronic lymphocytic leukaemia.

BACKGROUND: Chronic lymphocytic leukaemia (CLL) is the most common lymphoproliferative disease in adults and currently remains incurable. As the progression-free period shortens after each successive treatment, strategies such as maintenance therapy are needed to improve the degree and duration of response to previous therapies. Monoclonal antibodies, immunomodulatory agents, and targeted therapies are among the available options for maintenance therapy. People with CLL who achieve remission after previous therapy may choose to undergo medical observation or maintenance therapy to deepen the response. Even though there is widespread use of therapeutic maintenance agents, the benefits and harms of these treatments are still uncertain. OBJECTIVES: To assess the effects and safety of maintenance therapy, including anti-CD20 monoclonal antibody, immunomodulatory drug therapy, anti-CD52 monoclonal antibody, Bruton tyrosine kinase inhibitor, and B-cell lymphoma-2 tyrosine kinase inhibitor, for individuals with CLL. SEARCH METHODS: We conducted a comprehensive literature search for randomised controlled trials (RCTs) with no language or publication status restrictions. We searched CENTRAL, MEDLINE, Embase, and three trials registers in January 2022 together with reference checking, citation searching, and contact with study authors to identify additional studies. SELECTION CRITERIA: We included RCTs with prospective identification of participants. We excluded cluster-randomised trials, cross-over trial designs, and non-randomised studies. We included studies comparing maintenance therapies with placebo/observation or head-to-head comparisons. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures. We assessed risk of bias in the included studies using Cochrane's RoB 1 tool for RCTs. We rated the certainty of evidence for the following outcomes using the GRADE approach: overall survival (OS), health-related quality of life (HRQoL), grade 3 and 4 adverse events (AEs), progression-free survival (PFS), treatment-related mortality (TRM), treatment discontinuation (TD), and all adverse events (AEs). MAIN RESULTS: We identified 11 RCTs (2393 participants) that met the inclusion criteria, including seven trials comparing anti-CD20 monoclonal antibodies (mAbs) (rituximab or ofatumumab) with observation in 1679 participants; three trials comparing immunomodulatory drug (lenalidomide) with placebo/observation in 693 participants; and one trial comparing anti-CD 52 mAbs (alemtuzumab) with observation in 21 participants. No comparisons of novel small molecular inhibitors were found. The median age of participants was 54.1 to 71.7 years; 59.5% were males. The type of previous induction treatment, severity of disease, and baseline stage varied among the studies. Five trials included early-stage symptomatic patients, and three trials included advanced-stage patients (Rai stage III/IV or Binet stage B/C). Six trials reported a frequent occurrence of cytogenic aberrations at baseline (69.7% to 80.1%). The median follow-up duration was 12.4 to 73 months. The risk of selection bias in the included studies was unclear. We assessed overall risk of performance bias and detection bias as low risk for objective outcomes and high risk for subjective outcomes. Overall risk of attrition bias, reporting bias, and other bias was low. Anti-CD20 monoclonal antibodies (mAbs): rituximab or ofatumumab maintenance versus observation Anti-CD20 mAbs maintenance likely results in little to no difference in OS (hazard ratio (HR) 0.94, 95% confidence interval (CI) 0.73 to 1.20; 1152 participants; 3 studies; moderate-certainty evidence) and likely increases PFS significantly (HR 0.61, 95% CI 0.50 to 0.73; 1255 participants; 5 studies; moderate-certainty evidence) compared to observation alone. Anti-CD20 mAbs may result in: an increase in grade 3/4 AEs (rate ratio 1.34, 95% CI 1.06 to 1.71; 1284 participants; 5 studies; low-certainty evidence); little to no difference in TRM (risk ratio 0.82, 95% CI 0.39 to 1.71; 1189 participants; 4 studies; low-certainty evidence); a slight reduction to no difference in TD (risk ratio 0.93, 95% CI 0.72 to 1.20; 1321 participants; 6 studies; low-certainty evidence); and an increase in all AEs (rate ratio 1.23, 95% CI 1.03 to 1.47; 1321 participants; 6 studies; low-certainty evidence) compared to the observation group. One RCT reported that there may be no difference in HRQoL between the anti-CD20 mAbs (ofatumumab) maintenance and the observation group (mean difference -1.70, 95% CI -8.59 to 5.19; 480 participants; 1 study; low-certainty evidence). Immunomodulatory drug (IMiD): lenalidomide maintenance versus placebo/observation IMiD maintenance therapy likely results in little to no difference in OS (HR 0.91, 95% CI 0.61 to 1.35; 461 participants; 3 studies; moderate-certainty evidence) and likely results in a large increase in PFS (HR 0.37, 95% CI 0.19 to 0.73; 461 participants; 3 studies; moderate-certainty evidence) compared to placebo/observation. Regarding harms, IMiD maintenance therapy may result in an increase in grade 3/4 AEs (rate ratio 1.82, 95% CI 1.38 to 2.38; 400 participants; 2 studies; low-certainty evidence) and may result in a slight increase in TRM (risk ratio 1.22, 95% CI 0.35 to 4.29; 458 participants; 3 studies; low-certainty evidence) compared to placebo/observation. The evidence for the effect on TD compared to placebo is very uncertain (risk ratio 0.71, 95% CI 0.47 to 1.05; 400 participants; 2 studies; very low-certainty evidence). IMiD maintenance therapy probably increases all AEs slightly (rate ratio 1.41, 95% CI 1.28 to 1.54; 458 participants; 3 studies; moderate-certainty evidence) compared to placebo/observation. No studies assessed HRQoL. Anti-CD52 monoclonal antibodies (mAbs): alemtuzumab maintenance versus observation Maintenance with alemtuzumab may have little to no effect on PFS, but the evidence is very uncertain (HR 0.55, 95% CI 0.32 to 0.95; 21 participants; 1 study; very low-certainty evidence). We did not identify any study reporting the outcomes OS, HRQoL, grade 3/4 AEs, TRM, TD, or all AEs. AUTHORS' CONCLUSIONS: There is currently moderate- to very low-certainty evidence available regarding the benefits and harms of maintenance therapy in people with CLL. Anti-CD20 mAbs maintenance improved PFS, but also increased grade 3/4 AEs and all AEs. IMiD maintenance had a large effect on PFS, but also increased grade 3/4 AEs. However, none of the above-mentioned maintenance interventions show differences in OS between the maintenance and control groups. The effects of alemtuzumab maintenance are uncertain, coupled with a warning for drug-related infectious toxicity. We found no studies evaluating other novel maintenance interventions, such as B-cell receptor inhibitors, B-cell leukaemia-2/lymphoma-2 inhibitors, or obinutuzumab.

Endovascular thrombectomy for basilar-artery occlusion: A meta-analysis with trial sequential analysis.

Background and purpose: Basilar-artery occlusion (BAO) usually accounts for devastating neurologic sequelae, poor prognosis, and even death. While endovascular thrombectomy (EVT) is the most successful treatment for anterior circulation stroke with large vessel occlusion, its effectiveness in treating acute BAO is still debatable. Our aim is to compare the efficacy and safety between EVT and conservative medical treatment (CMT) in BAO. Methods: Up until May 2022, relevant literature was gathered using searches in Embase, PubMed, and the Cochrane Library. The primary outcomes were defined as good functional outcome (modified Rankin Scale 0-2) and favorable functional outcome (modified Rankin Scale 0-3) at 3 months between EVT and CMT groups. The secondary outcomes included mortality at 3 months, symptomatic intracerebral hemorrhage (ICH), and any ICH. Results: Eight studies involving 3733 patients with BAO were enrolled 2573 individuals underwent EVT, and the remaining 1160 patients received CMT. Compared with CMT, EVT achieved more favorable functional outcome (odds ratio (OR) 1.26, 95% CI 1.03-1.55, I2 = 54%, p = 0.05) in BAO. The good functional outcome showed a similar tendency (OR 1.23, 95% CI 0.97-1.57, I2 = 63%, p = 0.02) as well. EVT decreased mortality at 3 months (OR 0.81, 95% CI 0.70-0.93, I2 = 31 %, p = 0.19), although having a tendency to cause symptomatic ICH (OR 2.91, 95% CI 1.38-6.18, I2 = 22 %, p = 0.27). Conclusions: EVT in BAO provides superior functional outcomes and less mortality compared with CMT. Even though EVT has the propensity to cause symptomatic ICH, EVT nevertheless improved posterior circulation stroke.

Progression-Free Survival Efficacy in Refractory/Relapsed Multiple Myeloma among Elderly Patients: A Systematic Review.

BACKGROUND: Over the last decade, many studies have assessed the efficacy of treatments for refractory/relapsed multiple myeloma (R/R MM). While combination therapies show greater efficacy than traditional methods, limited research has targeted elderly patients who might be less resilient to treatments. Our study aimed to evaluate treatment efficacy for these elderly patients. METHODS: We carried out a comprehensive review of the literature using a systematic approach. Initially, 4966 citations were retrieved and subsequently narrowed down to 13 eligible randomized controlled trials (RCTs) through our systematic review process from databases like Embase, PubMed, and Cochrane Library from 1 January 2000 to 31 December 2022. Evidence was collated through a frequentist network meta-analysis, using the hazard ratio (HR) for evaluation. RESULTS: Combined therapy of daratumumab, lenalidomide, and dexamethasone (DaraLenDex) was the preferred treatment for R/R MM elderly patients. Its strengths included an HR for progression-free survival (0.15; 95% CI: 0.09-0.25) and a 96% P-score. CONCLUSIONS: Our analysis suggests that, pending more comprehensive RCTs, DaraLenDex is the treatment with the highest efficacy for R/R MM in elderly patients.

Comparative Evaluation of Tissue Adhesives and Sutures in the Management of Facial Laceration Wounds in Children.

BACKGROUND: This study evaluated tissue adhesives in comparison to sutures for treating facial lacerations in children. METHODS: We retrospectively analyzed data from September 2017 to August 2022 involving pediatric facial lacerations managed with either tissue adhesives or sutures. RESULTS: Among 50 children, 20 received tissue adhesives, and 30 received sutures. Both methods showed comparable outcomes in terms of wound complications such as dehiscence (adjusted odds ratio = 1.56, 95% CI = 0.08-31.25) and infection (adjusted odds ratio = 2.17, 95% CI = 0.08-58.80). The cosmetic outcomes, assessed using the Hollander Wound Evaluation Score, were also consistent between groups (adjusted beta = -0.55, 95% CI = -1.15-0.05). Notably, those treated with tissue adhesives reported greater satisfaction (adjusted beta = 1.13, 95% CI = 0.63 -1.63) and experienced significantly less pain (adjusted beta = -3.03, 95% CI = -4.15--1.90). CONCLUSIONS: Both techniques displayed similar rates of infection, dehiscence, and cosmetic outcomes. However, tissue adhesives were associated with increased patient comfort, especially in terms of reduced pain and greater satisfaction.

Profiling of miRNAs and their interfering targets in peripheral blood mononuclear cells from patients with chronic myeloid leukaemia.

Introduction: MicroRNAs may be implicated in the acquisition of drug resistance in chronic myeloid leukemia as they regulate the expression of not only BCR-ABL1 but also genes associated with the activation of drug transfer proteins or essential signaling pathways. Methods: To understand the impact of specifically expressed miRNAs in chronic myeloid leukemia and their target genes, we collected peripheral blood mononuclear cells (PBMC) from patients diagnosed with chronic myeloid leukemia (CML) and healthy donors to determine whole miRNA expression by small RNA sequencing and screened out 31 differentially expressed microRNAs (DE-miRNAs) with high expression. With the utilization of miRNA set enrichment analysis tools, we present here a comprehensive analysis of the relevance of DE-miRNAs to disease and biological function. Furthermore, the literature-based miRNA-target gene database was used to analyze the overall target genes of the DE-miRNAs and to define their associated biological responses. We further integrated DE-miRNA target genes to identify CML miRNA targeted gene signature singscore (CMTGSS) and used gene-set enrichment analysis (GSEA) to analyze the correlation between CMTGSS and Hallmark gene-sets in PBMC samples from clinical CML patients. Finally, the association of CMTGSS stratification with multiple CML cell lineage gene sets was validated in PBMC samples from CML patients using GSEA. Results: Although individual miRNAs have been reported to have varying degrees of impact on CML, overall, our results show that abnormally upregulated miRNAs are associated with apoptosis and aberrantly downregulated miRNAs are associated with cell cycle. The clinical database shows that our defined DE-miRNAs are associated with the prognosis of CML patients. CMTGSS-based stratification analysis presented a tendency for miRNAs to affect cell differentiation in the blood microenvironment. Conclusion: Collectively, this study defined differentially expressed miRNAs by miRNA sequencing from clinical samples and comprehensively analyzed the biological functions of the differential miRNAs in association with the target genes. The analysis of the enrichment of specific myeloid differentiated cells and immune cells also suggests the magnitude and potential targets of differentially expressed miRNAs in the clinical setting. It helps us to make links between the different results obtained from the multi-faceted studies to provide more potential research directions.

Negative pressure wound management in perineal wound status post abdominoperineal resection and extralevator abdominoperineal excision: a meta-analysis and trial sequential analysis.

PURPOSE: Recent evidence-based publications disclosed that negative pressure wound therapy (NPWT) may reduce the incidence rate of surgical site infection (SSI) and length of stay (LOS) compared with conventional drainage in patient status post abdominoperineal resection (APR) and extralevator abdominoperineal excision (ELAPE). METHODS: Data sources: Eligible randomized controlled trials and retrospective and prospective studies published before January 2023 were retrieved from databases (Cochrane Library, PubMed, and Embase). STUDY SELECTION: (a) The study involved patients undergoing ELAPE or APR with postoperative NPWT; (b) the study compared NWPT with conventional drainage and reported at least one outcome of interest (i.e., SSI); and (c) the study provided adequate information to calculate the effect estimated for meta-analysis. INTERVENTIONS: We calculated the odds ratio (ORs) and mean differences (MDs) with 95% confidence intervals (CIs). MAIN OUTCOME MEASURES: The measure outcomes included surgical site infection(SSI) and length of stay (LOS). RESULTS: Eight articles, involving 547 patients, met the selection criteria. Compared to conventional drainage, NPWT was associated with a significantly lower SSI rate (fixed effect, OR 0.29; 95% CI 0.18-0.45; I2 = 0%) in eight studies and 547 patients. Besides, NPWT was associated with a shorter LOS (fixed effect, MD - 2.00; CI - 2.60 to - 1.39; I2 = 0%) than conventional drainage in three studies and 305 patients. In a trial sequential analysis, the cumulative number of patients in the analyses of both outcomes exceeded the required information size and surpassed the significance boundary in favor of NPWT, suggesting conclusive results. CONCLUSION: NPWT is superior to conventional drainage in both SSI rate and LOS, and the statistical power of SSI and LOS are confirmed by trial sequential analysis.

Timing and Dose of Constraint-Induced Movement Therapy after Stroke: A Systematic Review and Meta-Regression.

The aim of this study is to investigate the effects of constraint-induced movement therapy on stroke patients who had intact cognition and some voluntary finger extension and to identify optimal protocols to apply this therapy method. We searched PubMed, Cochrane Library, and Embase for randomized controlled trials conducted prior to January 2022. The outcomes included the Motor Activity Log, Fugl-Meyer Assessment, and Wolf Motor Function Test. The inverse variance method fixed-effect model as well as the DerSimonian and Laird estimator random-effects model were applied, and the mean difference was calculated with 95% confidence interval to measure continuous outcomes. Six randomized controlled trials involving a total of 169 patients with stroke were enrolled. Compared with conventional rehabilitation methods, there was no significant effect of constraint-induced movement therapy when evaluated by the Motor Activity Log, including the amount of use (random-effect, standardized mean difference 0.65; 95%, confidence interval: -0.23-1.52) and quality of movement (random-effect, standardized mean difference 0.60; 95% confidence interval: -0.19-1.39). However, among patients with chronic stroke symptoms, meta-regression analyses showed better performance with a constraint time of at least 6 h per day and 6 h training per week when assessing the amount of use (p = 0.0035) and quality of movement (p = 0.0031). Daily intervention time did not lead to a significant difference in functional upper limb performance. An efficient protocol of constraint-induced movement therapy designed as 6 h of training per week with 6 h constraint per day could bring significant stroke symptom improvement to patients with chronic stroke.

Is Thrombocytopenia an In-Hospital Mortality Risk Factor among Patients with Acute Ischemic Stroke? A Propensity Score-Matched Analysis from the MIMIC-IV Database.

(1) Background: We aimed to evaluate the aspect of thrombocytopenia in patients with acute ischemic stroke (AIS); (2) Methods: Patients with AIS were recruited in the Medical Information Mart for Intensive Care IV database from 2008 to 2019. The thrombocytopenia was defined as a platelet blood count of less than 150 K/µL. We compared the patient characteristics and clinical outcomes using propensity score matching (PSM); (3) Results: Thrombocytopenia affected 151 out of the 1236 patients (12.2%). Patients with thrombocytopenia were older (70.5 ± 12.8 vs. 68.4 ± 14.4; SMD = 0.154) and had a higher Charlson comorbidity index (7.3 ± 2.5 vs. 6.7 ± 2.7; SMD = 0.228) and acute physiology score III (44.8 ± 21.0 vs. 38.2 ± 19.1; SMD = 0.328) than those without thrombocytopenia. The risk of in-hospital mortality did not increase linearly or nonlinearly with a lower platelet count (overall p value = 0.794; nonlinear p value = 0.646). After PSM, 147 pairs remained. Thrombocytopenia was not linked with in-hospital mortality (HR: 1.06, 95% CIs: 0.60-1.88); (4) Conclusions: We described the clinical characteristics of patients admitted for thrombocytopenia and AIS who did not receive reperfusion therapy; additionally, we found that thrombocytopenia was not an independent short-term risk factor of in-hospital mortality.

Incentive spirometry is an effective strategy to improve the quality of postoperative care in patients.

Postoperative pulmonary complications (PPCs) most commonly occur after thoracic surgery. Not only prolonged hospital stay and increased financial expenses but also morbidity and even mortality may be troublesome for those with PPCs. Herein, we aimed to conduct a comprehensive systematic review and meta-analysis of available data to examine the effectiveness of incentive spirometry (IS) to reduce PPCs and shorten hospital stay. This systematic review and meta-analysis included 5 randomized controlled trials (RCT) and 3 retrospective cohort study (10,322 patients in total) in PubMed, Embase and Cochrane Library until September 31, 2021. We assessed the clinical efficacy of IS using length of hospital stay, PPCs, postoperative pneumonia, and postoperative atelectasis with meta-analysis, meta-regression and trial sequential analysis (TSA). With this meta-analysis, the length of hospital stay in patients undergoing IS was significantly shorter (1.8 days) than that in patients not receiving IS (MD = -1.80, 95% CI = -2.95 to -0.65). Patients undergoing IS also had reduced risk of PPCs (32%) and postoperative pneumonia (17.9%) with statistical significance than patients not undergoing IS (PPC: OR = 0.68, 95% CI = 0.51-0.90) (Pneumonia: OR = 0.821, 95% CI = 0.677-0.995).In meta-regression, the benefits of undergoing IS in patients with preoperative predicted FEV1 of <80% in a linear fashion with decreasing PPCs. IS is an effective modality to improve the quality of postoperative care for patients after pulmonary resection, compared with the control group without using IS; and applying IS has favorable outcomes of shorter length of hospital stay (1.8 days) and lower occurrence of PPCs (32% of risk reduction), which are conclusive and robust based on our validation via TSA. Moreover, the IS device is more beneficial for patients with preoperative predicted FEV1 of <80% than that in others.

Intravitreal injection versus systematic treatment in patients with uveitis undergoing cataract surgery: a systematic review and meta-analysis.

PURPOSE: Cataract surgery in patients with uveitis is challenging, and postoperative inflammation control is crucial for successful outcomes. No consensus exists regarding the optimal method of controlling postoperative inflammation. In this systematic review and meta-analysis, we compared the outcome of intravitreal injection (IVI), including steroid (triamcinolone acetonide) or steroid implant (dexamethasone), with systemic anti-inflammatory therapy (ST), such as systemic steroids with or without immunomodulatory therapy, in patients with uveitis undergoing cataract surgery. METHODS: We searched PubMed, EMBASE, and Cochrane Library databases for randomized controlled trials (RCTs), comparative cohort studies, and case-control studies published through May 2021 that compared intraoperative IVI of triamcinolone acetonide or steroid implant with ST with or without immunomodulatory therapy. The following outcomes were evaluated: preoperative best-corrected visual acuity, intraocular pressure, laser flare photometry, central macular thickness and cystoid macular edema rate. RESULTS: Five studies were selected. Our analysis indicated that compared with ST, IVI treatment may be associated with less anterior chamber inflammation and a lower cystoid macular edema rate, but the difference in best-corrected visual acuity, intraocular pressure, or central macular thickness was not significant. CONCLUSIONS: IVI of steroid or steroid implants might be beneficial in controlling postoperative inflammation for uveitis cataract, especially in patients who cannot tolerate ST. To the best of our knowledge, this is the first meta-analysis to compare the efficacy of intraoperative IVI of steroids with standard-of-care treatment as a prophylaxis for uveitis cataract. However, large-scale RCTs are warranted to compare the IVI of steroid implants and steroids.

Endovascular therapy for acute ischemic stroke in patients with active malignancy: a meta-analysis with trial sequential analysis.

BACKGROUND: Active malignancy has a poorer prognosis and more deaths in patients with acute ischemic stroke (AIS). The outcomes of endovascular therapy (EVT) remain controversial in patients with AIS and active malignancy. METHODS: We searched PubMed, Cochrane, and Embase for articles published up to June 1, 2022. The primary outcome was good functional outcome at 3 months and successful reperfusion between patients with cancer and AIS and control patients. The secondary and safety outcomes included mortality at 3 months, in-hospital mortality, symptomatic intracerebral hemorrhage (sICH), any ICH, and subarachnoid hemorrhage (SAH). RESULTS: Twelve studies involving 5944 patients with AIS secondary to EVT were included (389 patients having active malignancy). The OR of good functional outcome at 3 months was 0.53 (95% CI 0.41 to 0.67) between the two groups. The OR of successful reperfusion between the two groups was 0.90 (95% CI 0.63 to 1.30). Compared with patients without cancers, those with cancers had a higher risk of mortality at 3 months (OR 3.64; 95% CI 2.35 to 6.27) and in-hospital mortality (OR 3.46; 95% CI 1.71 to 7.01). Despite a higher point estimate regarding any ICH (OR 1.41; 95% CI 1.01 to 1.96) and SAH (OR 2.53; 95% CI 1.10 to 5.81), sICH (OR 0.85; 95% CI 0.51 to 1.42) was not significant. CONCLUSION: Although a quarter of patients with active malignancy and AIS regained functional independence, physicians and patients should consider whether to apply EVT in patients with active malignancy.

Effect and Optimal Timing of Extracorporeal Shock-Wave Intervention to Patients With Spasticity After Stroke: A Systematic Review and Meta-analysis.

OBJECTIVE: This study investigated the efficacy of extracorporeal shock wave therapy as well as the optimal intervention timing for extracorporeal shock wave therapy for patients with spasticity after stroke. DESIGN: A search of randomized controlled trials was conducted in different electronic databases. We performed a meta-analysis to measure the effect of extracorporeal shock wave therapy versus sham interventions on spasticity and limb functionality. The meta-regression analysis was performed to determine the adequate intervention timing of extracorporeal shock wave therapy. The follow-up period of the outcomes was divided into the short (<2 wks), mid (>2 wks and ≤4 wks), and long (>4 wks and ≤3 mos) terms. RESULTS: Thirteen studies with 677 participants were evaluated. Spasticity significantly improved throughout the follow-up duration. Limb functionality significantly improved in the short-term follow-up period. The meta-regression analysis showed that patients with stroke duration less than 45 mos may be benefited from extracorporeal shock wave therapy in improving limb function in all follow-up periods. CONCLUSIONS: Extracorporeal shock wave therapy is an effective method for reducing spasticity in patients with stroke, and the effect could be maintained for up to 3 mos. Its effects on limb functionality could persist for at least 2 wks. Patients who had stroke for less than 45 mos may have significant benefit from extracorporeal shock wave therapy in all follow-up periods.

Effectiveness of different root-end filling materials in modern surgical endodontic treatment: A systematic review and network meta-analysis.

Background/purpose: There is controversial evidence on the best choice for root-end filling materials in follow-up periods and treatment protocols. The purpose of this study was to evaluate the effectiveness of different root-end filling materials in modern surgical endodontic treatment. Materials and methods: A total of 16 studies with a minimum follow-up of 12-months were qualified to be reviewed, involving randomized control trials and observational studies in PubMed, Cochrane library and Scopus until September 1, 2021. The outcome of modern surgical endodontic treatment was assessed based on clinical and radiographic success. Direct comparisons were combined to estimate indirect comparisons, and the estimated effect size was analyzed using the odds ratio (OR). The comparative effectiveness of all materials for target outcomes were shown as P-score. Results: Within this network meta-analysis, mineral trioxide aggregate (MTA) had superior effects among all root-end filling materials at 12-months follow-up. (MTA: OR, 2.03; 95% CI, 0.84-4.91; P-score, 0.86; reference material, gutta-percha). In further sensitivity analyses, MTA, calcium silicate-based root repair material (RRM) and super EBA cement (Super EBA) were associated with significantly higher success rates at 12-months follow-up. (MTA: OR, 5.62; 95% CI, 1.58-19.99; P-score, 0.88; RRM: OR, 5.23; 95% CI, 1.05-25.98; P-score, 0.74; Super EBA: OR, 3.99; 95% CI, 1.06-15.04; P-score, 0.54; reference material, gutta-percha). Conclusion: MTA remains the best choice for root-end filling materials of modern surgical endodontic treatment at the 12-month follow-up. Comparative randomized clinical trials in the long-term follow-up are warranted in future investigations.

The Role of Nondiabetic Hyperglycemia in Critically Ill Patients with Acute Ischemic Stroke.

In this study, we aim to elucidate the association between nondiabetic hyperglycemia and the short-term prognosis of critically ill patients with acute ischemic stroke. We extracted data using the Medical Information Mart for Intensive Care IV from 2008 to 2019. The primary outcomes were set as intensive care units (ICU) and in-hospital mortality. We developed a Cox proportional hazards model to determine the nonlinear association between serum glucose levels and primary outcomes. Of the 1086 patients included, 236 patients had hyperglycemia. Patients with hyperglycemia were associated with higher ages, female gender, higher Charlson Comorbidity Index scores, and higher Acute Physiology Score III scores. After propensity score matching, 222 pairs remained. The hyperglycemia group had a significantly higher ICU mortality (17.6% vs. 10.8%; p = 0.041). Meanwhile, no significant differences in ICU length of stay (5.2 vs. 5.2; p = 0.910), in-hospital mortality (26.6% vs. 18.9%, p = 0.054), and hospital length of stay (10.0 vs. 9.1; p = 0.404) were observed between the two groups. The Kaplan-Meier curves for ICU and in-hospital survival before matching suggested significant differences; however, after matching, they failed to prove any disparity. Non-diabetic patients with acute ischemic stroke have poor clinical characteristic while encountering hyperglycemic events; therefore, careful monitoring in the acute phase is still required.

Effect of Lenalidomide Maintenance in Chronic Lymphocytic Leukemia: A Meta-Analysis and Trial-Sequential Analysis.

Chronic lymphocytic leukemia (CLL) is the most common lymphoproliferative disease in adults. Despite durable responses and sustained remission rates to frontline therapy, CLL is still incurable within standard therapy and eventually relapses. Maintenance therapies aim to achieve deep remission. However, the efficacy and safety of lenalidomide maintenance are still debated. Randomized controlled trials published before March 2022 were retrieved from databases. Primary outcomes were progression-free survival (PFS) and overall survival (OS). Trial sequential analysis examined analytical power in primary outcomes. Secondary outcomes were Grade 3-4 neutropenia, treatment discontinuation (TD), serious adverse events (SAE), and fatal adverse events (FAE). Hazard (HR) and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Four articles (733 patients) met the selection criteria. Lenalidomide maintenance was associated with a statistically significant effect in prolonging PFS (HR, 0.43; 95% CI, 0.28-0.68; I2 = 57%) and higher proportion of SAE (OR 4.64; 95% CI 2.96-7.26; I2 = 0%) and exhibited no difference in OS (HR, 0.62; 95% CI, 0.29-1.30; I2 = 52%) observation/placebo. It showed no significant difference compared with observation/placebo regarding Grade 3-4 neutropenia (OR 2.30; 95% CI 0.84-6.28; I2 = 81%), TD (OR 0.76; 95% CI 0.29-1.99; I2 = 84%), and FAE (OR 0.86; 95% CI 0.28-2.63; I2 = 0%). Lenalidomide maintenance can prolong PFS in CLL. Further studies should verify its effect on OS.
