The Incidence of Suicide Following Metabolic and Bariatric Surgery: A Prognosis Systematic Review and Meta-Analysis of Longitudinal Studies.

BACKGROUND: Metabolic and bariatric surgery (MBS) effectively manages severe obesity but may lead to psychological complications such as completed suicides and suicide attempts. This review aimed to analyze suicide and self-harm incidence post-MBS. METHODS: We searched MEDLINE, EMBASE, PsycINFO, and the Cochrane Library databases on August 16, 2022, for longitudinal studies with incidence data on suicide following MBS. We performed a single proportion meta-analysis on the incidence of outcomes and assessed the certainty of evidence using the GRADE approach. The review was registered with PROSPERO (CRD42022352137). RESULTS: Eighty-four studies were included. The meta-analysis showed an incidence of 230.64 suicides per 100,000 participants (95% CI: 167.51 to 317.49) in pooled individual-level data and an incidence of 43.02 suicides per 100,000 person-years (95% CI: 32.49 to 56.97) in pooled person-year data. Evidence was low certainty or very low certainty. CONCLUSIONS: The average suicide incidence (231 per 100,000 people) in people with obesity who underwent MBS significantly exceeded the 2019 WHO global estimate for the general population (nine per 100,000 people). These findings underscore the need to incorporate structured psychological screening and follow-up into the perioperative management process of MBS, as patient mental health may play a pivotal role in postoperative adherence and long-term outcomes.

Ultrasound-Guided Microwave Ablation Versus Open Surgery for Benign Breast Disease: Impact on Postoperative Lactation.

BACKGROUND: Benign breast disease (BBD) is common in adult women. While ultrasound-guided microwave ablation (MWA) is an established minimally invasive treatment, its comparative impact on postoperative lactation, particularly mastitis, remains understudied. This study aimed to evaluate mastitis outcomes following MWA versus open surgery for BBD. METHODS: In this retrospective study, 79 patients (105 nodules) treated between January 2018 and August 2023 were included 41 patients (62 nodules) underwent MWA and 38 patients (43 nodules) underwent open surgery. All patients lactated within 5 years post-procedure. The primary outcome was the incidence of lactational mastitis without systemic symptoms (MWoSS) and mastitis with systemic symptoms (MSS). Patient satisfaction was also assessed. RESULTS: The incidence of MWoSS was significantly lower in the MWA group (19.5%) than in the open surgery group (50.0%). Similarly, MSS occurred in 4.9% of the MWA group versus 34.2% of the open surgery group. Multivariate analysis identified open surgery as an independent risk factor, associated with a 4.13-fold increased risk of MWoSS (OR = 4.125, 95% CI: 1.517-11.218) and a 10.14-fold increased risk of MSS (OR = 10.140, 95% CI: 2.107-48.793). Patient satisfaction was significantly higher in the MWA group (9.29 &#xb1; 0.72 vs. 8.15 &#xb1; 1.13, p < 0.001). CONCLUSION: Compared to open surgery, ultrasound-guided MWA for BBD is associated with a significantly lower risk of postoperative mastitis and higher patient satisfaction, supporting its use for women of reproductive age, particularly when future breastfeeding is planned.

Stapled versus hand-sewn intestinal anastomosis in pediatric surgery: A systematic review and meta-analysis.

BACKGROUND: Intestinal anastomosis is a core procedure in pediatric gastrointestinal surgery, performed for conditions such as necrotizing enterocolitis, intestinal atresia, Hirschsprung's disease, and inflammatory bowel disease. Although stapled anastomosis (SA) may improve operative efficiency, its safety and effectiveness compared with hand-sewn anastomosis (HA) in children remain uncertain. This meta-analysis compared clinical outcomes of SA and HA in pediatric patients. METHODS: The study followed PRISMA guidelines and was prospectively registered in PROSPERO (CRD420251177257). A systematic search of PubMed, Dimensions, and the Cochrane Library was conducted through June 2025. Studies including children under 7 years undergoing intestinal SA or HA were eligible. Two reviewers independently performed study selection, data extraction, and risk-of-bias assessment using ROB 2 and ROBINS-I tools. Statistical analysis was conducted using Comprehensive Meta-Analysis software (v3) with a random-effects model. RESULTS: Eleven studies involving 903 patients met inclusion criteria, including two randomized controlled trials. Of these, 333 patients underwent SA and 570 underwent HA. SA was associated with significantly shorter operative time (mean difference [MD] = -19.26 min; 95% CI: -24.24 to -14.28; p < 0.001) and earlier initiation of oral feeding (MD = -2.32 days; 95% CI: -3.78 to -0.86; p = 0.002). No significant differences were found in anastomotic leakage, stricture formation, reoperation rate, or length of hospital stay. CONCLUSIONS: Stapled anastomosis appears as safe as hand-sewn techniques in pediatric intestinal surgery while offering shorter operative duration and faster postoperative feeding recovery. Selective use of stapled techniques is supported when anatomically feasible, though further multicenter randomized trials are needed.

Comparison of ultrasound-guided two-point block of the rhomboid intercostal vs. thoracic paravertebral for postoperative analgesia in patients undergoing three-port thoracoscopic surgery: a prospective, randomized, non-inferiority study.

BACKGROUND: The anesthetic characteristics of ultrasound-guided two-point rhomboid intercostal block (RIB) have not been fully established. This study compared the analgesic efficacy of ultrasound-guided two-point RIB with that of two-point thoracic paravertebral block (TPVB) for postoperative pain control and recovery in patients undergoing three-port thoracoscopic surgery. METHODS: Seventy patients aged 18-80&#x2009;years scheduled for three-port thoracoscopic pulmonary resection were block-randomized in a 1:1 ratio to receive either TPVB or RIB. Both techniques were performed using 10&#x2009;mL of 0.5% ropivacaine at each injection site. The primary outcome was the numerical rating scale (NRS) pain score at rest 24&#x2009;h after surgery, with a predefined non-inferiority margin of &#x394;&#x2009;=&#x2009;1. Secondary outcomes included NRS at rest and during coughing at 0.5, 2, 4, 12, 18, 24, and 48&#x2009;h postoperatively, as well as the 24h postoperative Quality of Recovery-40 (QoR-40) score. RESULTS: The final analysis included 34 patients in the TPVB group and 34 in the RIB group. The mean difference in resting NRS scores at 24&#x2009;h between the two groups was 0.088 (95% CI, -0.377 to 0.553), confirming the non-inferiority of RIB. However, the need for rescue analgesia was numerically greater in the RIB group than in the TPVB group (p&#x2009;=&#x2009;0.045). The 24-h postoperative QoR-40 scores and cumulative sufentanil consumption within 48&#x2009;h after surgery were comparable between the groups (both p&#x2009;>&#x2009;0.05). CONCLUSION: Ultrasound-guided two-point RIB provided postoperative analgesia that was non-inferior to TPVB in patients undergoing three-port thoracoscopic surgery.

Complication rates of 16- and 18-gauge needles for native kidney biopsies: a systematic review and proportional meta-analysis.

This systematic review and meta-analysis evaluated complication rates and diagnostic yield reported in studies of adult native kidney biopsy using 16-gauge (16&#x2009;G) or 18-gauge (18&#x2009;G) needles. We included randomized trials and cohort studies of real-time ultrasound-guided biopsies, including case series. MEDLINE, Embase, and CENTRAL were searched through October 2024. Two reviewers independently performed study selection, data extraction, and risk of bias assessment using Joanna Briggs Institute tools. Random-effects meta-analyses estimated pooled proportions with 95% confidence intervals (CI), and univariable random-effects meta-regression explored study-level associations with major complications, transfusion, or gross hematuria. We screened 4,499 titles and abstracts and reviewed 319 full-text articles; 62 studies comprising 68 biopsy series were included. The pooled major complication rate in studies using 16&#x2009;G needles was 1.83% (95% CI: 1.20-2.79) and 1.29% (95% CI: 0.78-2.13) in studies using 18&#x2009;G needles, with no statistically significant difference. Mean glomerular yield was 18.8 with 16&#x2009;G and 17.5 with 18&#x2009;G needles. In study-level meta-regression, studies with higher prevalence of acute kidney injury, lower mean estimated glomerular filtration rate, or lower mean hemoglobin reported higher pooled complication rates. Most studies were single-arm cohorts; between-needle differences therefore reflect indirect study-level contrasts. Interpretation is limited by retrospective design and heterogeneity across studies. Overall, studies using both needle sizes reported low complication rates and similar diagnostic yield, although definitions and reporting varied. Direct comparative studies are needed to determine whether meaningful differences exist.

Intravenous thrombolysis for ischemic stroke in extended time window selected with CT perfusion: a systematic review and meta-analysis.

PURPOSE: Recent randomized controlled trials (RCTs) have provided new evidence regarding the efficacy and safety of intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS) presenting within the extended time window (ETW). We performed a systematic review and meta-analysis to evaluate the efficacy and safety of IVT, in patients treated within the ETW and selected with perfusion imaging criteria, predominantly computed tomography perfusion (CTP). METHODS: A systematic review and meta-analysis, registered in PROSPERO, was conducted including all available RCTs comparing IVT with best medical treatment (BMT) in patients with AIS within the ETW, selected using advanced perfusion imaging criteria. The predefined efficacy outcomes were excellent functional outcome and good functional outcome at 3 months. The safety endpoints included symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days. RESULTS: Six RCTs, including 1182 patients treated with IVT and 1176 patients receiving BMT, were included. IVT was associated with a higher likelihood of achieving excellent and good functional outcomes at 3 months. Exploratory subgroup analyses by treatment timing suggested consistent findings up to 24 hours. No significant difference in 90-day mortality was observed between groups, whereas IVT was associated with an increased risk of sICH. CONCLUSION: Treatment with IVT in the ETW (4.5-24 h) in patients selected using advanced perfusion imaging, predominantly CTP, may be associated with improved functional outcomes in patients with AIS. Although IVT was associated with an increased risk of sICH, no significant increase in 90-day mortality was observed. PROSPERO REGISTRATION: CRD420261304314.

Virtual surgical planning-assisted versus free-hand head and neck reconstruction: Systematic review, meta-analysis, and a novel classification.

Virtual surgical planning (VSP)-assisted reconstruction is increasingly used as an alternative to conventional free-hand (FH) techniques in mandibular and maxillary free-flap reconstruction. This systematic review and meta-analysis compared clinical outcomes and proposed a Reconstruction Complexity-Completeness classification. PubMed/MEDLINE, Scopus, Web of Science, Google Scholar, and reference lists were searched from inception to 20 June 2026. Comparative studies were eligible. Risk of bias was assessed using RoB 2 or the Newcastle-Ottawa Scale. Random-effects meta-analyses used restricted maximum likelihood estimation and Hartung-Knapp adjustment. Forty-two studies included 2763 patients (1204 VSP; 1559 FH). VSP significantly reduced operative time (33 studies; MD -64.75&#x202f;min, 95% CI -83.51 to -46.00), ischemia time (15 studies; MD -37.40&#x202f;min, 95% CI -48.97 to -25.82), and hospital stay (16 studies; MD -1.75 days, 95% CI -3.43 to -0.08). VSP was associated with significantly lower odds of bony non-union (OR 0.31, 95% CI 0.16-0.59) and malocclusion (OR 0.14, 95% CI 0.03-0.64), whereas flap loss, surgical site infection, and plate exposure did not differ significantly. VSP-assisted reconstruction was associated with improved operative efficiency, shorter hospitalization, and lower odds of bony non-union and malocclusion, while no statistically significant differences were detected in flap loss, surgical site infection, or plate exposure. The proposed classification may support complexity-adjusted reporting and comparison.

Clinical Efficacy and Learning Curve of Far-Lateral Approach (FLA) in Uni-Portal Non-Coaxial Spinal Endoscopic Surgery (UNSES) in the Treatment of Lumbar Degenerative Diseases: A Prospective Study.

BACKGROUND: Uniportal non-coaxial spinal endoscopic surgery (UNSES) via far-lateral approach (FLA) is an innovative minimally invasive procedure for lumbar degenerative diseases, particularly far-lateral disc herniation and foraminal stenosis. However, complex lateral lumbar anatomy and strict endoscope-instrument coordination create a distinct learning curve that may compromise early surgical efficiency and safety. This study aimed to evaluate the efficacy and safety, quantify the learning curve, and to provide clinical guidance for the standardized promotion and application of this technology. METHODS: A total of 40 consecutive patients with lumbar degenerative diseases who underwent UNSES via FLA by a single surgeon between January 2025 and December 2025 were included. All data were analyzed using SPSS 26.0 statistical software (IBM, USA). Primary outcomes included operation time, blood loss, fluoroscopy frequency, and intraoperative complication rate. Secondary outcomes were VAS, ODI, and modified Macnab criteria at 1, 3, and 6&#x2009;months postoperatively. The learning curve and the inflection point of the learning curve was determined using cumulative sum (CUSUM) analysis. The differences in clinical indicators between early and proficient stage were compared. RESULT: Operation time, blood loss, and fluoroscopy times decreased significantly with case accumulation (p&#x2009;<&#x2009;0.05). CUSUM identified an inflection point at the 16th case, after which operation time stabilized at (55.3&#x2009;&#xb1;&#x2009;8.6) min, much shorter than the early phase (89.5&#x2009;&#xb1;&#x2009;10.3) min (p&#x2009;<&#x2009;0.001). Before the 16th case, the curve was in an upward trend; after the 16th case, the curve tended to be flat, indicating the proficiency stage. Postoperative VAS and ODI improved significantly than those before surgery at each follow-up time (p&#x2009;<&#x2009;0.05). There was no significant difference in postoperative VAS score and ODI between the two groups at each follow-up time point (p&#x2009;>&#x2009;0.05). The total complication rate was 12.5% (5/40), were cured by conservative treatment. The total excellent-good rate was 90.0% (36/40). L5/S1 and Bertolotti's syndrome were independent factors affecting the learning curve. CONCLUSION: UNSES via FLA is a safe and effective minimally invasive technique for treating complex lumbar degenerative diseases. It has a certain learning curve, and the inflection point is about the 16th case. After mastering the key techniques such as anatomical positioning, endoscopic manipulation and hemostasis, the surgeon can gradually reach the proficiency stage, with significantly improved surgical efficiency and clinical efficacy, and controllable complications. This study provides a theoretical basis for the clinical training and technology promotion of UNSES via FLA.

Early mobilization within 24 to 48&#xa0;h improves postoperative clinical outcomes in older adults with hip fracture: A systematic review and meta-analysis.

BACKGROUND: Hip fracture is a major public health concern among older adults, often resulting in prolonged disability, institutionalization, and increased healthcare burden. Early mobilization has been widely recommended to enhance postoperative recovery; however, there is a lack of consolidated evidence quantifying its impact on clinical and functional outcomes. This study aimed to synthesize and evaluate the impact of early mobilization following hip fracture surgery in older adults and to explore potential sources of heterogeneity to better inform clinical and nursing practice. METHODS: A comprehensive literature search was conducted across seven databases (PubMed, Embase, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, and Emcare) from inception to June 15, 2025. Eligible studies included randomized controlled trials and observational cohort studies comparing early mobilization (defined as ambulation within 24 to 48&#xa0;h postoperatively) to delayed or usual mobilization in patients undergoing hip fracture surgery. Primary outcomes included mortality, discharge destination, and length of hospital stay. Secondary outcomes included postoperative complications, functional recovery, and readmission. Risk of bias was assessed using funnel plots and Egger's test. RESULTS: Twenty-six studies involving 297,435 patients were included. Compared with delayed mobilization, early mobilization significantly reduced 30-day mortality (relative risk&#xa0;=&#xa0;0.40, 95% confidence interval: 0.25-0.64) and 1-year mortality (relative risk&#xa0;=&#xa0;0.57, 95% confidence interval: 0.40-0.80) (both p&#xa0;<&#xa0;0.05). In regional analyses of pooled mortality, similar reductions were observed across Asia-Pacific, North America, and Europe. Patients receiving early mobilization were more likely to be discharged home and had shorter hospital stays. Early mobilization also resulted in a reduced risk of postoperative complications (relative risk&#xa0;=&#xa0;0.79, 95% confidence interval: 0.74-0.84, p&#xa0;<&#xa0;0.05), with specific improvements in pneumonia and thromboembolism rates. Functional independence was significantly improved, as shown by higher Barthel Index scores and increased odds of achieving Functional Independence Measure &#x2265;5 at discharge. No significant difference was observed in readmission rates. CONCLUSIONS: lization within 24 to 48&#xa0;h following hip fracture surgery was associated with favorable outcomes, including reduced mortality, improved functional independence, higher rates of discharge to home, shorter hospital length of stay, and fewer postoperative complications. Although heterogeneity across studies and the predominance of observational evidence warrant cautious interpretation, these findings support current recommendations for early mobilization and highight the potential value of structured and standardized mobilization protocols in routine postoperative hip fracture care.

Minimally invasive versus open surgery for gallbladder cancer: A systematic review and meta-analysis.

INTRODUCTION: Minimally invasive surgery (MIS) is increasingly being used in gallbladder cancer (GBC) for radical tumour extirpation. However, there are conflicting results on the morbidity outcomes following MIS. The aim of this meta-analysis was to compare the post-operative morbidity and mortality in patients undergoing radical surgery for GBC between MIS and open surgery. MATERIAL AND METHODS: Studies comparing MIS (laparoscopic, robotic or both techniques) to open surgery were included. The databases of MEDLINE, Cochrane and EMBASE were searched from 2001 till March 2025. The primary end point was post-operative morbidity and mortality. The secondary end points were hospital stay, blood loss, operative time and R1 resection rates. Random effect models were used for analysis. The risk of bias was assessed using the Newcastle-Ottawa scale. RESULTS: Thirty-two studies (laparoscopic [n&#x202f;=&#x202f;19], robotic [n&#x202f;=&#x202f;6] or both [n&#x202f;=&#x202f;7]) involving 8568 (MIS&#x202f;=&#x202f;3287 and open&#x202f;=&#x202f;5281) patients were included. For overall and major morbidity (Clavian-Dindo >/&#x202f;=&#x202f;III), the odds ratio (OR) of 0.60 (95% CI: 0.46-0.78) and 0.72 (95% CI: 0.52-1.0) respectively was obtained, favouring the MIS approach. Similarly, MIS showed lower odds for mortality [OR:0.62 (95% CI: 0.40-0.95)] compared to open surgery. MIS was associated with shorter hospital stay (less by mean of 3 days) and lesser blood loss (less by mean of 115&#x202f;ml) but longer operative time (higher by mean of 5.8&#x202f;min) and higher R1 resection rates (OR: 1.34; 95% CI: 1.05-1.71). Oncological outcomes, however, were comparable. The certainty of evidence was very low to low across the studies. CONCLUSION: MIS for GBC was associated with relatively lower post operative morbidity and mortality with similar oncological outcomes but with a small but heightened risk of margin positive (R1) resection, especially in primary GBC. The certainty of evidence was very low to low across the included studies. Future prospective studies are needed to overcome the clinical heterogeneity and possible selection bias.

Effects of single-injection vs. continuous brachial plexus blocks for shoulder surgeries on patient-reported outcomes: a systematic review and meta-analysis with trial sequential analysis of randomised controlled trials.

INTRODUCTION: Single-injection and continuous brachial plexus block techniques are used widely for postoperative analgesia in patients undergoing shoulder surgery. Although patient-reported outcomes are described in individual studies, their effects have not been synthesised comprehensively using a patient-centred framework. We sought to compare the effects of single-injection vs. continuous brachial plexus block techniques on patient-reported outcomes in adult patients following elective shoulder surgery. METHODS: Databases were searched from inception to October 2025 and randomised controlled trials reporting patient-reported outcomes were included. Co-primary outcomes were postoperative patient-reported pain intensity at rest and during movement at 12&#x2009;h, 24&#x2009;h and 48&#x2009;h post-surgery. Secondary outcomes included nausea and vomiting; sleep quality; patient satisfaction; opioid requests; and functional scores. Random-effects meta-analysis and trial sequential analysis were performed, with risk of bias and quality of patient-reported outcome reporting assessed. RESULTS: Twenty randomised controlled trials that included 1198 patients were analysed. Continuous brachial plexus blocks were associated with lower pain at rest at 12&#x2009;h, 24&#x2009;h and 48&#x2009;h, with mean differences (MD) of -1.96 (95%CI -2.81 to -1.11, p&#x2009;<&#x2009;0.001), -1.66 (95%CI -2.27 to -1.05, p&#x2009;<&#x2009;0.001) and&#x2009;-&#x2009;1.18 (95%CI -1.84 to -0.53, p&#x2009;<&#x2009;0.001), respectively. Pain on movement could only be pooled at 24&#x2009;h and 48&#x2009;h and showed MD -2.04 (95%CI -4.26-0.19, p&#x2009;=&#x2009;0.07) and&#x2009;-&#x2009;1.30 (95%CI -3.67-1.07, p&#x2009;=&#x2009;0.28) respectively. The co-primary outcomes approached or exceeded the predefined minimal clinically important difference for pain scores after shoulder surgery, in favour of continuous techniques. DISCUSSION: Continuous brachial plexus blocks are associated with better pain at rest and other patient-centred outcomes following shoulder surgery, while effects on dynamic pain and long-term functional recovery remain uncertain.

Impact of oliceridine versus sufentanil on postoperative nausea and vomiting in patients undergoing thyroid surgery: a prospective, double-blind, randomized controlled trial.

PURPOSE: Postoperative nausea and vomiting (PONV) is a common complication following thyroid surgery, often exacerbated by opioid use. Oliceridine, a novel G protein-biased &#x3bc;-opioid receptor agonist, may reduce opioid-related adverse events. This study aimed to compare the impact of oliceridine versus sufentanil on the incidence and severity of PONV in patients undergoing thyroid surgery. PATIENTS AND METHODS: In this prospective, double-blind, randomised controlled trial conducted between May 2025 and February 2026, 232 patients scheduled for thyroid surgery were randomly assigned to receive either oliceridine or sufentanil for intraoperative analgesia. The primary outcome was the incidence of PONV during the first 48&#x2009;h postoperatively. Secondary outcomes included PONV severity, need for rescue anti-emetics, postoperative pain scores, recovery quality, and other adverse events. RESULTS: The incidence of PONV within 48&#x2009;h postoperatively was significantly lower in the oliceridine group [13/107 (12%)] compared with the sufentanil group [31/110 (28%)] (OR = 0.35, 95% CI: 0.17-0.72, p&#x2009;=&#x2009;0.006). Postoperative pain scores, rescue analgesia requirements, and Quality of Recovery-15 scores were comparable between the two groups (p&#x2009;>&#x2009;0.05). Besides, exploratory unadjusted analyses revealed fewer rescue anti-emetics: O group 8/107 (8%) vs S group 25/110 (23%) (OR = 0.27, 95% CI: 0.12-0.64, p&#x2009;=&#x2009;0.002); and less abdominal distension: O group 4/107 (4%) vs S group 19/110 (17%) (OR = 0.19, 95% CI: 0.06-0.57, p&#x2009;=&#x2009;0.001). CONCLUSION: For young ASA I-II patients undergoing thyroid surgery, oliceridine yields adequate postoperative analgesia and lower PONV rates versus sufentanil. Additional trials involving high-intensity surgical procedures are needed to confirm consistent equivalence.

Waterborne norovirus outbreaks in China, 2000-2022: a systematic review.

In China, waterborne transmission is a relatively rare route for norovirus outbreaks; however, once it occurs, the outbreaks tend to be large in scale, prolonged in duration, and difficult to control. This systematic review characterizes the epidemiological features of such outbreaks in China. We searched the WANFANG, CNKI, PubMed, and Web of Science databases for literature on waterborne norovirus outbreaks published up to November 2023. From 2000 to 2022, a total of 112 outbreaks were reported in China among the 97 articles included. These outbreaks involved approximately 19,796 cases and 565,485 exposures, median of 98 cases per outbreak, with a median attack rate of 6.09&#x202f;%. Most outbreaks occurred in southern regions, particularly in coastal provinces, with schools (59, 52.68&#x202f;%) and towns or villages (25, 22.52&#x202f;%) being the most common settings. The highest number of outbreaks was reported in February and the lowest in July, with an average of 8.25 outbreaks per month. Higher attack rates were associated with outbreaks occurring in winter, in primary schools, and in southern regions of the Qinling-Huaihe line. Contamination of barreled water and self-provided wells was the primary risk factor for waterborne norovirus outbreaks. Although waterborne transmission is a relatively rare route for norovirus outbreaks in China, it can cause large-scale outbreaks in a short period. Consequently, it is still necessary to enhance protection of water sources, rigorous water quality monitoring, and public health education on water sanitation.

Prothrombin complex concentrate (PCC) vs. non-PCC strategies for warfarin reversal in left ventricular assist device recipients: A systematic review and meta-analysis.

BACKGROUND: Left ventricular assist devices (LVADs) prolong survival in end-stage heart failure, and warfarin thromboprophylaxis is recommended to prevent device thrombosis and thromboembolic complications. When bleeding occurs or emergency surgery is required, rapid anticoagulation reversal is critical. Prothrombin complex concentrate (PCC) provides rapid reversal; however, its risk-benefit profile in LVAD recipients remains unclear. We conducted a systematic review and meta-analysis comparing PCC with non-PCC strategies for warfarin reversal in LVAD recipients. METHODS: MEDLINE, Embase, and Scopus were searched through June 2025 for studies of PCC versus non-PCC strategies for warfarin reversal in LVAD recipients. Two reviewers independently extracted data. Random-effects models were used to pool arm-level estimates and to pool head-to-head comparisons using mean differences or risk ratios (RRs). RESULTS: Eighteen studies involving 779 patients were included. Arm-level pooled estimates for PCC versus non-PCC comparators were 24.0% versus 15.8% for mortality, 16.5% versus 12.1% for thrombotic events, and 3.1 versus 5.7 for FFP units. Arm-level time to INR correction was longer with PCC overall (16.5 versus 13.6&#xa0;h), driven by one elective cohort, but faster within the ICH subgroup (6.0 versus 13.7&#xa0;h). In head-to-head comparisons, PCC achieved faster INR correction than non-PCC comparators (mean difference&#xa0;-&#xa0;7.6&#xa0;h; p&#xa0;=&#xa0;0.001) and required fewer FFP units (-2.6&#xa0;units; p&#xa0;=&#xa0;0.019), with no significant difference in all-cause mortality (RR 1.14; p&#xa0;=&#xa0;0.490) or thrombotic events (RR 1.43; p&#xa0;=&#xa0;0.176). CONCLUSIONS: In head-to-head studies, PCC was associated with faster INR correction and lower FFP requirements than non-PCC strategies, whereas mortality and thrombotic events did not differ significantly. Given the observational evidence, wide confidence intervals, and heterogeneity, equivalent safety cannot be established, and prospective studies are needed to define the relative safety and effectiveness of the two approaches. IMPLICATIONS FOR CLINICAL PRACTICE: PCC-based strategies may be considered for urgent warfarin reversal in LVAD recipients, particularly when rapid INR reduction or avoidance of large-volume plasma transfusion is clinically important. Treatment decisions should account for the indication, bleeding severity, and underlying thrombotic risk. TRIAL REGISTRATION: CRD42024573925.

Comparative efficacy and safety of bi-flanged metal stents versus lumen-apposing metal stents for endoscopic drainage of pancreatic fluid collections: a systematic review and meta-analysis.

INTRODUCTION: Pancreatic fluid collections (PFCs), particularly walled-off necrosis, are common complications of acute pancreatitis that often require endoscopic drainage. Bi-flanged metal stents (BFMS; NAGI; Taewoong Medical, Gyenoggi-do, Korea) and electrocautery-enhanced lumen-apposing metal stents (LAMS; AXIOS, Boston Scientific Corporation, Marlborough, Massachusetts, USA) are frequently used, but comparative data remain limited. This study aims to compare the efficacy and safety of BFMS and LAMS in the endoscopic drainage of PFCs. METHODS: This meta-analysis followed the Cochrane Handbook for Systematic Reviews of Interventions and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Comprehensive database searches were conducted through November 2024 to identify studies comparing BFMS and LAMS for endoscopic ultrasound-guided drainage of PFCs. Outcomes were pooled using a random-effects model with RevMan Web, and statistical significance was defined as a P value less than 0.05. RESULTS: Three studies ( n &#x2005;=&#x2005;627; 329 BFMS and 298 LAMS) met inclusion criteria. No significant differences were observed between BFMS and LAMS for technical success [odds ratio (OR): 1.16; 95% confidence interval (CI): 0.55-2.43] or clinical success (OR: 0.97; 95% CI: 0.51-1.87). Similarly, there were no differences in walled-off necrosis recurrence (OR: 2.01; 95% CI: 0.17-24.02), number of direct endoscopic necrosectomy sessions (OR: 0.52; 95% CI: 0.05-5.12), or mean number of endoscopic procedures (mean difference: 0.18, 95% CI: 2.08-2.45). Adverse events were also comparable between groups, including bleeding (OR: 0.64), infection (OR: 1.18), stent migration (OR: 1.83), and stent occlusion/dysfunction (OR: 1.71). CONCLUSION: BFMS and LAMS provide equivalent efficacy and safety in the endoscopic ultrasound-guided drainage of PFCs. Either stent type represents a viable therapeutic option. Further large-scale prospective studies are warranted to refine stent selection strategies.

The use of diode laser and scalpel blade in stage-two dental implant surgery: a comparative study.

OBJECTIVE: The use of lasers in dental implant procedures raises questions regarding the preservation of keratinized tissues and implant outcomes. This study aimed to compare the clinical effects (pain and impression time) and soft tissue healing (keratinization, peri-implant probing, bleeding, and healing) of diode lasers and scalpels used during stage-two dental implant surgery. METHOD AND MATERIALS: A prospective randomized clinical trial with a 1:1 allocation ratio was conducted. The study included 30 patients, each with a single, fully osseointegrated implant. Patients were categorized into two groups. The study group underwent stage-two implant surgery using a 970-nm diode laser. In the control group, implants were exposed using a conventional surgical blade. A comparison between the diode laser and conventional scalpel groups was made based on clinical outcomes (pain and impression time) and soft tissue healing (keratinization, peri-implant probing, bleeding, and healing). Data were analyzed using a paired t test. RESULTS: Pain intensity significantly decreased from immediate postoperative to 7 days in both scalpel (49.87 &#xb1; 6.78, t = 28.48, df = 14, P .001) and diode laser (7.67 &#xb1; 7.58, t = 3.91, df = 14, P = .002) groups. Immediately after surgery, pain scores were significantly higher in the scalpel group compared with the diode laser group (94.53 &#xb1; 4.45 vs 46.93 &#xb1; 5.85, t = 25.076, df = 26.151, P .001). Although pain decreased in both groups by day 7, the scalpel group continued to exhibit significantly greater pain (44.67 &#xb1; 5.96 vs 39.27 &#xb1; 3.73, t = 2.974, df = 23.513, P = .007). Impression time (P = .231) and gingival keratinized tissue (P = .736) did not differ significantly between the scalpel and diode laser approaches. At week 6, the scalpel group exhibited a significantly higher mean peri-implant bleeding index (2.60 &#xb1; 0.507) compared with the laser group (0.07 &#xb1; 0.258, P .001). However, after 12 weeks, no significant difference was observed (1.58 &#xb1; 0.19 vs 1.55 &#xb1; 0.21, P = .748). Laser surgery produced significantly better early wound healing at all intervals (P .001), while intraoperative bleeding was more common with the scalpel technique than with the diode laser (100.0% vs 66.7%, P = .042). CONCLUSION: Compared with the scalpel method, the diode laser method resulted in a significant reduction in pain intensity, improved wound healing, and less peri-implant bleeding during the stage-two dental implant surgery.

Thoracic paravertebral block with different doses of liposomal bupivacaine versus ropivacaine for postoperative analgesia in single-port thoracoscopic lung surgery: a randomized clinical trial.

OBJECTIVE: To evaluate the analgesic efficacy of thoracic paravertebral block (TPVB) with different doses of liposomal bupivacaine (LB) or ropivacaine in patients undergoing single-port thoracoscopic lung surgery. METHODS: A total of 105 patients scheduled for video-assisted single-port thoracoscopic lung surgery were randomized in a 1:1:1 ratio into three groups: low-dose LB group (group LL), high-dose LB group (group HL), or ropivacaine group (group R). All received ultrasound-guided TPVB at the T5/6 level preoperatively. The primary outcome was the area under the curve (AUC) of NRS of pain at activity (AUC-aNRS) from 1 to 72&#x2009;h postoperatively. Secondary outcomes included the AUC of NRS of pain at rest (AUC-rNRS) from 1 to 72&#x2009;h postoperatively, NRS of pain at rest and at activity at 1, 6, 24, 48, and 72&#x2009;h postoperatively, and the cumulative opioid consumption at 24, 48, and 72&#x2009;h postoperatively. Additionally, postoperative recovery and adverse events were assessed. RESULTS: AUC-aNRS differed significantly among groups (p = 0.0092), with high-dose LB lower than low-dose LB (p = 0.0071), but not versus ropivacaine. No significant difference was found in AUC-rNRS (p&#x2009;>&#x2009;0.05). The group-by-time interactions for NRS of pain at rest and at activity were not significant (p&#x2009;>&#x2009;0.05). Cumulative opioid consumption at 24, 48, and 72&#x202f;h was lower in group HL versus group LL (all p < 0.017), but not versus ropivacaine. Postoperative recovery and adverse events showed no differences (p&#x2009;>&#x2009;0.05). CONCLUSION: LB combined with TPVB is not superior to ropivacaine for postoperative analgesia in single-port thoracoscopic lung resection.
