Electrocautery vs. Stapler in Comparing Safety for Segmentectomy of Lung Cancer: A Meta-Analysis

Background: Electrocautery and staplers are regarded as the two most common surgical instruments for dissecting the intersegmental plane in segmentectomy. We performed a meta-analysis to compare electrocautery and staplers in terms of their safety and effects.Methods: A systematic search strategy was performed using PubMed, and the retrieval time was up to April 1, 2020. Odds ratio (OR) and mean differences (MDs) with 95% CI were applied to determine the effectiveness of dichotomous or continuous variables, respectively.Results: Six studies including 385 patients were included. The electrocautery had a higher incidence rate of postoperative complication [OR= 1.92, 95% CI (1.12, 3.28), P = 0.02)] and air leak [OR: 3.91, 95% CI (1.64, 9.35), P = 0.002)]. No significant difference was found in the comparison of surgery time, blood loss, and duration of tube days or hospitality days.Conclusions: Our study indicated that patients under segmentectomy were associated with better safety by using stapler than electrocautery in the reduction of postoperative complications.

: Breast cancer is the most common neoplasm, comprising 16% of all women's cancers worldwide. Research of Copper (Cu) concentrations in various body specimens have suggested an association between Cu levels and breast cancer risks. This systematic review and meta-analysis summarize the results of published studies and examine this association. We searched the databases PubMed, Scopus, Web of Science, and Google Scholar and the reference lists of relevant publications. The Standardized Mean Differences (SMDs) between Cu levels in cancer cases and controls and corresponding Confidence Intervals (CIs), as well as I2 statistics, were calculated to examine heterogeneity. Following the specimens used in the original studies, the Cu concentrations were examined in three subgroups: serum or plasma, breast tissue, and scalp hair. We identified 1711 relevant studies published from 1984 to 2017. There was no statistically significant difference between breast cancer cases and controls for Cu levels assayed in any studied specimen; the SMD (95% CI) was -0.01 (-1.06 - 1.03; P = 0.98) for blood or serum, 0.51 (-0.70 - 1.73; P = 0.41) for breast tissue, and -0.88 (-3.42 - 1.65; P = 0.50) for hair samples. However, the heterogeneity between studies was very high (P < 0.001) in all subgroups. We did not find evidence for publication bias (P = 0.91). The results of this meta-analysis do not support an association between Cu levels and breast cancer. However, due to high heterogeneity in the results of original studies, this conclusion needs to be confirmed by well-designed prospective studies.

Abstract Objective To perform a meta-analysis comparing the structural progression and clinical symptom outcomes as well as adverse events experienced from intra-articular injections of sprifermin compared to a placebo treatment for patients with knee osteoarthritis (KOA). Method We systematically searched the literature for studies that compared long-term outcomes between sprifermin and placebo injections for KOA treatment. Meta-analysis was performed with RevMan5.3 using an inverse variance approach with fixed or random effects models. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated. Results Eight studies were included. Overall, there was significantly less improvement of WOMAC total scores in patients receiving sprifermin, compared with the placebo (mean difference (MD) = 3.23, 95% CI 0.76–5.69; I2 = 0%; P = 0.01). Further, sprifermin injection patients gained more, and lost less, cartilage thickness and volume in total femorotibial joint (cartilage thickness: standardized mean differences (SMD) = 0.55, 95% CI 0.26–0.84; I2 = 78%; P = 0.0002; cartilage volume: SMD = 0.39, 95% CI 0.20–0.58; I2 = 49%; P < 0.0001). Changes in the cartilage surface morphology of the medial tibio-femoral joint (MD = −0.30, 95% CI −0.44 to −0.16; I2 = 0%; P < 0.0001) and patello-femoral joint (MD = −0.22; 95% CI −0.37 to −0.07; I2 = 0%; P = 0.004) showed a significant difference between the sprifermin and placebo injections. Moreover, there were no significant differences between sprifermin and the placebo in the risk of treatment-emergent adverse events (OR = 1.05; 95% CI 0.52–2.14; I2 = 48%; P = 0.89). Conclusion The data from the included studies provide strong evidence to determine the effect of intra-articular sprifermin on joint structure in individuals with KOA and show no specific adverse effects. Nevertheless, intra-articular sprifermin did not likely have any positive effect on symptom alleviation.

Due to overcrowding, personnel shortages, or problematic intravenous (IV) cannulation, acute pain management is often sub-optimal in emergency departments (EDs). The objective of this systematic review and meta-analysis was to evaluate the efficacy and safety of intranasal (IN) ketamine for adult acute pain in the emergency setting. We searched and identified studies up to 21 May 2021 via PubMed, Scopus, Web of Science, Cochrane Database, and Google Scholar. The random-effects model with 95% confidence intervals (CIs) was used to estimate mean differences (MDs) and odds ratios (ORs). The I2 statistic and Cochran’s Q test were used to determine heterogeneity. The protocol was registered in PROSPERO (CRD42020213391). Seven randomised controlled trials were included with a total of 1760 patients. There was no significant difference in pain scores comparing IN ketamine with IV analgesics or placebo at 5 (MD 0.94, p = 0.26), 15 (MD 0.15, p = 0.74), 25 (MD 0.24, p = 0.62), 30 (MD −0.05, p = 0.87), and 60 (MD −0.42, p = 0.53) minutes. There was also no significant difference in the need for rescue analgesics between IN ketamine and IV analgesics (OR 1.66, 95% CI: 0.57−4.86, p = 0.35, I2 = 70%). Only mild adverse effects were observed in patients who received IN ketamine. Our results suggest that IN ketamine is non-inferior to IV analgesics and may have a role in acute pain management among adults in the ED.

Objective: To evaluate the efficacy and safety of short-wave therapy with sham or no intervention for the management of patients with knee osteoarthritis. Methods: We searched the following databases from their inception up to 26 October 2016: MEDLINE, CENTRAL, EMBASE, Physiotherapy Evidence Database, CINAHL and OpenGrey. Studies included randomized controlled trials compared with a sham or no intervention in patients with knee osteoarthritis. The results were calculated via standardized mean difference (SMD) and risk ratio for continuous variables outcomes as well as dichotomous variables, respectively. Heterogeneity was explored by the I2 test and inverse-variance random effects analysis was applied to all studies. Results: Eight trials (542 patients) met the inclusion criteria. The effect of short-wave therapy on pain was found positive (SMD, −0.53; 95% CI, −0.84 to −0.21). The pain subgroup showed that patients received pulse modality achieved clinical improvement (SMD, –0.83; 95% CI, –1.14 to −0.52) and the pain scale in female patients decreased (SMD, −0.53; 95% CI, −0.98 to −0.08). In terms of extensor strength, short-wave therapy was superior to the control group ( p < 0.05, I2 = 0%). There was no significant difference in the physical function (SMD, −0.16; 95% CI, −0.36 to 0.05). For adverse effects, there was no significant difference between the treatment and control group. Conclusion: Short-wave therapy is beneficial for relieving pain caused by knee osteoarthritis (the pulse modality seems superior to the continuous modality), and knee extensor muscle combining with isokinetic strength. Function is not improved.

Abstract Objective To evaluate the effectiveness and safety of the biodegradable collagen matrix (Ologen) implant in trabeculectomy. Research design and methods We searched Pubmed, Cochrane library, Embase and Web of Science databases to find studies that met our pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. The search was finished by February 2019. Study selection, data extraction, quality assessment, and data analyses were performed according to the Cochrane standards. Either a fixed or a random-effects model was used to calculate the overall combined risk estimates. The efficacy measures were the weighted mean differences (WMDs) for the intraocular pressure reduction (IOPR) and the glaucoma medications reduction, the odds ratio (OR) for the success rate and adverse events. Results Fifteen randomized controlled trials involved 682 eyes were included in the meta-analysis. There were no statistically differences between two groups in the IOPR at any time postoperatively. The MD of the IOPR was [MD= -0.45,95% Confidence Interval (CI), (-2.36,1.46), P=0.65] at one day, [MD= -0.82,95% CI, (-1.97, 0.33), P=0.16] at one week, [MD= -1.33, 95% CI,(-3.12, 0.47), P=0.15] at one month, [MD= 0.11,95% CI, (-1.87, 2.08), P=0.92] at three months, [MD= -0.60,95% CI, (-2.27, 1.06), P=0.48] at six months, [MD= -0.33,95% CI, (-1.99, 1.32), P=0.69] at one year, [MD= -0.13,95% CI, (-1.90, 1.65), P=0.89] at two years, [MD= 2.54,95% CI, (-2.83, 7.90), P=0.35] at three years, [MD= 3.04,95% CI, (-3.95, 10.03), P=0.39] at five years. There was no statistically significant difference between the Ologen groups and MMC groups concerned the complete success rate [OR=1.19, 95%CI, (0.83, 1.71), P=0.35]. With regard to the adverse events, no obvirously significance was observed. Seven studies reported the change of antiglaucoma medications. We found that the change of antiglaucoma medications is higher in MMC groups than that in Ologen groups [MD=-0.18, 95%CI, (-0.33, -0.03), P=0.02]. There is no significant difference in complications between the two groups. Conclusions From the current evidence, Ologen may be an alternative choice for trabeculectomy when considering the efficacy and safety. However, MMC might be the preferred choice concerned cost-effectiveness.

Abstract Objectives Elbow flexion loss is a debilitating upper extremity injury. Surgical treatment options include nonfree muscle transfers (tendon transfers, nerve transfers, Steindler procedure, Oberlin transfers, and pedicled muscle transfers) or free muscle transfers. We sought to determine if free muscle transfers and nonfree muscle transfers have similar outcomes for elbow flexion reanimation. Materials and Methods A literature search for studies evaluating free and nonfree muscle transfers for elbow flexion reanimation was performed. Included studies reported on transfer failure (strength <M3, unable to flex arm against gravity), strength, range of motion (ROM), or Disabilities of the Arm, Shoulder, and Hand (DASH) score. Pooled odds ratios were used to calculate failure rate, and pooled mean differences were used to calculate differences in strength, ROM, and DASH scores. Results Six studies were included (n = 331 patients). Free muscle patients experienced lower failure rates than nonfree muscle patients. There was no significant difference in ROM. A nonsignificant trend toward better mean strength and DASH scores among free muscle patients was observed. Conclusion Free muscle transfers may be superior to nonfree muscle transfers for elbow flexion reanimation, given their lower failure rates. Well-powered future studies may reveal differences in strength and DASH scores between free and nonfree muscle transfers.

Background/Aims: The aim of this study was to assess the association between circulating cell-derived microparticles (MPs) and type 2 diabetes mellitus (T2DM). Methods: A literature search was performed systematically in PubMed and Embase to identify available case-control or cross-sectional studies that compared different types of cell-derived MPs in patients with T2DM and non-diabetic controls. Pooled standardized mean differences (SMDs) of each MP type were pooled using meta-analysis. Results: Forty-eight studies involving 2,460 patients with T2DM and 1,880 non-diabetic controls were included for systematic review and 34 of which were included for quantitative study by meta-analysis. In the overall analysis, the levels of circulating total MPs (TMPs), platelet-derived MPs (PMPs), monocyte-derived MPs (MMPs) and endothelium-derived MPs (EMPs) were significantly higher in T2DM patients than those in controls (TMPs: SMD, 0.64; 95%CI, 0.12∼1.15; P=0.02; PMPs: SMD, 1.19; 95%CI, 0.88∼1.50; P <0.00001; MMPs: SMD, 0.92; 95%CI, 0.66∼1.17; P <0.00001; EMPs: SMD, 0.73; 95%CI, 0.50∼0.96; P <0.00001). Meanwhile, no significant difference was shown in leukocyte-derived MPs (LMPs) level between diabetic and non-diabetic groups (SMD, 0.37; 95%CI, -0.15∼0.89; P=0.17). Conclusions: The counts of TMPs, PMPs, MMPs and EMPs elevated in patients with T2DM. And cell-derived MPs may play a role in the pathogenesis of T2DM.

Abstract Background and aims: Increased epicardial adipose tissue (EAT) has been proposed as a risk factor for essential hypertension (EH). The aim of this study was to investigate the association of EAT with EH.Methods and results: PubMed, EMBASE, and Cochrane databases were systematically reviewed to identify relevant studies assessing the association of EAT thickness (EAT-t) and volume (EAT-v) with EH. There were 39 observational studies and 8,983 subjects included in the meta-analysis. The analysis indicated that hypertensive patients had a higher mean of EAT-t (SMD=0.64, 95% CI: 0.44-0.83, p<0.001) and EAT-v (SMD: 0.69, 95% CI:0.34-0.1.05, p<0.001) than normotensive individuals. Accordingly, we calculated pooled odds ratio (OR) and 95% confidence intervals (CI) for the association of EAT with EH, and the results showed that EAT-t (OR: 1.59, 95% CI: 1.09–2.33, P<0.001) and EAT-v (OR: 1.82, 95% CI: 1.33–2.19, P<0.001) were associated with essential hypertension. Additionally, higher mean of EAT-t (SMD=0.85, 95% CI=0.49-0.1.21, p<0.001) and EAT-v (SMD=0.83, 95% CI=0.31-1.34, p=0.002) were found in non-dipper hypertensive patients than those in dipper patients, but we didn’t find significant difference in EAT-t among patients with different grades of hypertension. We also investigated the association of EAT with complications in hypertensive patients, and the results showed that EAT was increased in patients with arteriosclerotic cardiovascular disease (ASCVD) or cardiac hypertrophy and dysfunction than those without. Conclusions: The increase in EAT was associated with the occurrence and complications of EH. The findings provide new information regarding the occurrence and complications of EH.

Lisfranc Injuries

Aims This systematic review and meta-analysis was conducted to compare open reduction and internal fixation (ORIF) with primary arthrodesis (PA) in the treatment of Lisfranc injuries, regarding patient-reported outcome measures (PROMs), and risk of secondary surgery. The aim was to conclusively determine the best available treatment based on the most complete and recent evidence available. Methods A systematic search was conducted in PubMed, Cochrane Controlled Register of Trials (CENTRAL), EMBASE, CINAHL, PEDro, and SPORTDiscus. Additionally, ongoing trial registers and reference lists of included articles were screened. Risk of bias (RoB) and level of evidence were assessed using the Cochrane risk of bias tools and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The random and fixed-effect models were used for the statistical analysis. Results A total of 20 studies were selected for this review, of which 12 were comparative studies fit for meta-analysis, including three randomized controlled trials (RCTs). This resulted in a total analyzed population of 392 patients treated with ORIF and 249 patients treated with PA. The mean differences between the two groups in American Orthopedic Foot and Ankle Society (AOFAS), VAS, and SF-36 scores were -7.41 (95% confidence interval (CI) -13.31 to -1.51), 0.77 (95% CI -0.85 to 2.39), and -1.20 (95% CI -3.86 to 1.46), respectively. Conclusion This is the first study to find a statistically significant difference in PROMs, as measured by the AOFAS score, in favour of PA for the treatment of Lisfranc injuries. However, this difference may not be clinically relevant, and therefore drawing a definitive conclusion requires confirmation by a large prospective high-quality RCT. Such a study should also assess cost-effectiveness, as cost considerations might be decisive in decision-making. Level of Evidence: I Cite this article: Bone Jt Open 2021;2(10):842–849.

This meta-analysis was performed to resolve the inconsistencies regarding resistin and follistatin levels in women with polycystic ovary syndrome (PCOS) by pooling the available evidence. A systematic literature search using PubMed and Scopus was carried out through November 2020 to obtain all pertinent studies. Weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs) were calculated to evaluate the strength of the association between the levels of resistin and follistatin with PCOS in the overall and stratified analysis by obesity status. A total of 47 publications, 38 for resistin (2424 cases; 1906 controls) and 9 studies for follistatin (815 cases; 328 controls), were included in the meta-analysis. Resistin levels were significantly higher in PCOS women compared with non-PCOS controls (WMD = 1.96 ng/ml; 95%CI = 1.25–2.67, P≤0.001) as well as in obese PCOS women vs. obese controls, and in non-obese PCOS women compared with non-obese controls, but not in obese PCOS vs. non-obese PCOS patients,. A significantly increased circulating follistatin was found in PCOS patients compared with the controls (WMD = 0.44 ng/ml; 95%CI = 0.30–0.58, P≤0.001) and in non-obese PCOS women compared with non-obese controls and in obese PCOS women vs. obese controls, but, no significant difference in follistatin level was observed in obese PCOS compared with non-obese PCOS women. Significant heterogeneity and publication bias was evident for some analyses. Circulating levels of resistin and follistatin, independent of obesity status, are higher in women with PCOS compared with controls, showing that these adipokines may contribute to the pathology of PCOS.
