The aim of this meta-analysis was to compare the superiority of stump closure between stump invagination (SI) and simple ligation (SL) during open appendicectomy (OA). The literature searching was conducted in MEDLINE, EMBASE, the Cochrane Library, and http://scholar.google.com. Available data was extracted by 3 independent reviewers. The clinical outcomes were analyzed by meta-analytic software to compare the difference between 2 methods during OA. The pooled odds ratios (ORs) and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were obtained by using fixed effect model. Eleven randomized controlled trials (RCTs) were finally included in this study involving 2634 patients. Postoperative pyrexia and infections were similar between SL and SI groups, respectively, but the former group had a shorter operative time (WMD: 8.72; 95% CI: 6.87–10.56; P < 0.00001); less incidence of postoperative ileus (WMD: 2.02; 95% CI: 1.36–3.01; P = 0.0005); and quicker postoperative recovery (WMD: 0.30; 95% CI: 0.11–0.48; P = 0.002). The above results were based on 5, 11, 4, 11, and 9 articles, respectively. The clinical results revealed that SL was significantly superior to SI. SL should be suggested during OA.

Patients who undergo surgery of femur fracture suffer the excruciating pain. Dexmedetomidine (DEX) is a unique α2-adrenergic receptor agonist with sedative and analgesic properties, whose efficacy and safety are still unclear for surgery of femur fracture. Randomized controlled trials comparing the effects of addition of DEX to general or local anesthesia in surgery of femur fracture were searched from MEDLINE, EMBASE, and the Cochrane Library database. Patients who received DEX infusion had a significant longer time to rescue analgesia compared with those without DEX coadministration. DEX treatment seemed to reduce the visual analog score; however, the significance did not reach any statistical difference. DEX as an analgesic adjuvant did not reduce the onset of sensory block time, shorten the time to achieve maximum sensory block level, and provide a longer duration of sensory block. The difference in mean sedation scores between 2 groups was not statistically significant. As for adverse effects, DEX therapy significantly increased the rate of hypotension. In conclusion, dexmedetomidine as a local anesthetic adjuvant in femur fracture surgery had a longer duration of rescue analgesia. However, the incidence of hypotension was markedly increased in these patients. It was worth noting that the evidence was of low to moderate quality.

Objective To determine the association between serum visfatin levels and psoriasis and to evaluate the correlation between serum visfatin levels and the severity of psoriasis. Methods The electronic databases PubMed®, Embase® and the Cochrane Library were searched for articles published from inception to 1 May 2020. Data were extracted and then standard mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for pooled estimates. Results A total of 11 studies met the inclusion criteria and were included (448 patients diagnosed with psoriasis and 377 controls). This meta-analysis demonstrated that patients with psoriasis had significantly higher levels of visfatin than the controls (SMD = 0.90, 95% CI 0.52, 1.28). Subgroup analyses showed that differences in serum visfatin levels between the patient group and the control group were associated with ethnicity, Psoriasis Area and Severity Index (PASI) and body mass index. Additionally, a meta-analysis of correlations showed that visfatin levels in patients with psoriasis were positively correlated with PASI ( r = 0.51, 95% CI 0.14, 0.75). Conclusions This meta-analysis showed that serum visfatin levels in patients with psoriasis were significantly higher than those in the controls and a positive correlation between serum visfatin levels and psoriasis severity was observed.

Purpose. A meta-analysis was performed to compare the efficacy of an anterior chamber injection of moxifloxacin in the prevention of endophthalmitis after cataract surgery. Methods. A computer-based search of PubMed, Embase, the Cochrane Library, and the Clinical Trial database for articles related to anterior intraventricular injection of moxifloxacin for the prevention of endophthalmitis after cataract surgery was performed through April 2019. Study selection, data exclusion, and quality assessment were performed by two independent observers. Statistical analysis for the meta-analysis was performed by RevMan5.3 software. Results. Eight studies were included, with a total of 123,819 eyes. The meta-analysis showed that an anterior chamber injection of moxifloxacin can prevent the incidence of endophthalmitis after cataract surgery (OR = 0.29, 95% CI (0.15, 0.56), P=0.0002), and the difference was statistically significant. There were no significant differences between the moxifloxacin injection and nonmoxifloxacin injection groups in regard to UCVA (log MAR) (SMD = −0.13, 95% CI (−0.62, 0.35), P=0.60), BCVA (log MAR) (SMD = −0.27, 95% CI (−1.28, 0.74), P=0.60), IOP (SMD = −0.04, 95% CI (−0.02, 0.01), P=0.22), corneal edema (OR = 1.03, 95% CI (0.23, 4.69), P=0.97), CCT (SMD = −0.01, 95% CI (−0.07, 0.05), P=0.77), or ECD (SMD = 0.00, 95% CI (−0.06, 0.07), P=0.94). Conclusion. An anterior chamber injection of moxifloxacin can effectively prevent the incidence of endophthalmitis after cataract surgery, while the moxifloxacin injection and nonmoxifloxacin injection groups had similar results in regard to UCVA (log MAR), BCVA (log MAR), IOP, corneal edema, CCT, and ECD.

Background. Physical activity (PA) reduces incidence of colorectal cancer (CRC). Its influence on cancer-specific (CSS) and overall survival (OS) is controversial.Methods. We performed a literature-based meta-analysis (MA) of observational studies, using keywords “colorectal cancer, physical activity, and survival” in PubMed and EMBASE. No dedicated MA was found in the Cochrane Library. References were cross-checked. Pre- and postdiagnosis PA levels were assessed by MET. Usually, “high” PA was higher than 17 MET hour/week. Hazard ratios (HRs) for OS and CSS were calculated, with their 95% confidence interval. We used more conservative adjusted HRs, since variables of adjustment were similar between studies. When higher PA was associated with improved survival, HRs for detrimental events were set to <1. We used EasyMA software and fixed effect model whenever possible.Results. Seven studies (8056 participants) were included, representing 3762 men and 4256 women, 5210 colon and 1745 rectum cancers. Mean age was 67 years. HR CSS for postdiagnosis PA (higher PA versus lower) was 0.61 (0.44–0.86). The corresponding HR OS was 0.62 (0.54–0.71). HR CSS for prediagnosis PA was 0.75 (0.62–0.91). The corresponding HR OS was 0.74 (0.62–0.89).Conclusion. Higher PA predicted a better CSS. Sustained PA should be advised for CRC. OS also improved (reduced cardiovascular risk).

Abstract Background: To evaluate and compare corneal biomechanics after treatment of myopia using small-incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK). Methods: We performed a meta-analysis and searched for reports concerning corneal biomechanics after SMILE and FS-LASIK using MEDLINE, EMbase, CNKI and the Cochrane Library. The analysis included corneal hysteresis (CH) and corneal resistance factor (CRF) before and 3 months after the surgery. The quality of the reports was evaluated using the Newcastle-Ottawa scale (NOS). Statistical analysis was performed using RevMan5. Results: Only six studies with a total of 771 eyes were ultimately included in this meta-analysis, and the random effects model was adopted. The preoperative and three-month postoperative CH and CRF of SMILE and FS-LASIK were compared by the meta-analysis. No statistically significant difference was found in CH or CRF between the SMILE group and the FS-LASIK group before the surgery (WMD，-0.12; 95% CI，-0.31～0.06; P，0.19; WMD，-0.05; 95% CI，-0.29～0.19; P，0.69). There was no statistically significant difference in CH between the two surgical methods 3 months after the operation in the foreign group (WMD，0.19; 95% CI，-1.02～1.41; P，0.75) or in the Chinese group (WMD，0.13; 95% CI，-0.16～0.41; P，0.75). Likewise, no statistically significant difference was found in CRF between the two surgical methods in the foreign group 3 months after the operation (WMD，-0.11; 95% CI，-2.53～-2.31; P，0.93). Nevertheless, the difference in CRF between the two surgical methods was statistically significant in the Chinese group (WMD，0.26; 95% CI，0.06～0.47; P，0.01). Concusion: This meta-analysis indicated that SMILE showed no significant postoperative advantage in CH in comparison with FS-LASIK. For CRF, SMILE exhibited no obvious postoperative advantage in comparison with FS-LASIK in the foreign group, whereas SMILE was superior to FS-LASIK in the Chinese group.

Abstract ObjectiveThe pros and cons of the head-up position (HUP) in cardiopulmonary resuscitation (CPR) have been controversial in previous studies. This study aims to clarify the effect of HUP CPR compared to supine position (SUP) CPR.MethodThree databases were comprehensively searched (PubMed, EMBASE and the Cochrane Library) for articles published from database inception to 10 May 2021. The primary outcome was cerebral perfusion pressure (CerPP). The secondary outcomes were mean intracranial pressure (ICP), mean artery pressure (MAP), coronary artery perfusion pressure (CoPP) and the return of spontaneous circulation (ROSC) rate.ResultA total of 7 studies including 138 animals were included. We found that CerPP (SMD, 1.58; 95% CI, 0.98–2.19; p < 0.01; I2 = 51%) and ICP (SMD, -3.59; 95% CI, -5.16– -2.02; p < 0.01; I2 = 87%) were decreased significantly in the HUP group. HUP had a similar MAP (SMD, -0.54; 95% CI, -1.75–0.66; p = 0.38; I2 = 87%) and ROSC rate (RR, 0.9; 95% CI, 0.31–2.60; p = 0.84; I2 = 65%) to SUP. In addition, there was an increased CoPP trend in HUP, but the difference was not statistically significant (SMD, 0.92; 95% CI, -0.24–2.08; p = 0.12; I2 = 84%)ConclusionThe HUP 30° in active compression-decompression CPR (ACD-CPR) with an impedance threshold device (ITD) can increase CerPP by significantly lowering ICP and maintaining MAP compared to SUP, and the effect is immediate and lasts the whole CPR duration. In addition, CoPP might also be increased compared to that with SUP.

Abstract Background: Diabetes mellitus (DM) causes excess risk of fracture at varied sites. Whereas, the difference between the roles of types 1 DM (T1DM) and 2 DM (T2DM) diabetes in the risk of fractures remains limited and inconclusive. We, therefore, conducted a meta-analysis to assess the differences for the associations of T1DM and T2DM with the risk of fractures.Methods: We systematically searched PubMed, Embase, and the Cochrane library for eligible studies until May 2021. The odds ratios (ORs) with 95% confidence intervals (CIs) were used to calculate the pooled effect estimates for the associations of T1DM and T2DM with the risk of fractures using the random-effects model. An indirect comparison results for the ratio of OR (ROR) with 95% CI were also applied to assess the difference between T1DM and T2DM with the risk of fractures.Results: Twenty-two cohort studies involving a total of 6,484,851 individuals were selected for meta-analysis. We noted that T1DM was associated with an increased risk of all fractures (OR: 1.72; 95% CI: 1.36–2.19; P < 0.001), and fractures at the hip (OR: 4.01; 95% CI: 2.90–5.54; P < 0.001), upper arm (OR: 2.20; 95% CI: 1.61–3.00; P < 0.001), ankle (OR: 1.97; 95% CI: 1.24–3.14; P = 0.004), and vertebrae (OR: 2.18; 95% CI: 1.85–2.57; P < 0.001). Moreover, T2DM induced excess risk to all fractures (OR: 1.19; 95% CI: 1.09–1.31; P < 0.001), including fractures at the hip (OR: 1.25; 95% CI: 1.15–1.35; P < 0.001), upper arm (OR: 1.42; 95% CI: 1.20–1.67; P < 0.001), and ankle (OR: 1.15; 95% CI: 1.01–1.31; P = 0.029). Furthermore, we noted that T1DM versus T2DM was associated with greater risk to all fractures (ROR: 1.45; 95% CI: 1.12–1.87; P = 0.005), including fractures at the hip (ROR: 3.21; 95% CI: 2.30–4.48; P < 0.001), upper arm (ROR: 1.55; 95% CI: 1.09–2.20; P = 0.015), and ankle (ROR: 1.71; 95% CI: 1.06–2.78; P = 0.029).Conclusions: This study found that T1DM caused an excess risk to all fractures, including fractures at the hip, upper arm, and ankle than T2DM. Further studies should therefore be conducted to directly compare the differences between T1DM and T2DM with the risk of fractures at various sites.

Background: Aflibercept has been widely used in treating diabetic macular edema (DME). However, the effect of aflibercept in treating DME refractory to bevacizumab or ranibizumab has not been well established. Objective: To assess the therapeutic effect of switching from bevacizumab or ranibizumab to aflibercept in the treatment of refractory DME. Methods: Relevant studies were searched from 3 databases: the Cochrane Library, PubMed, and Web of Science. Data on changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and adverse events within the follow-up period were collected and pooled using weighted mean differences (WMDs) with corresponding 95% CIs in a random effects model. The between-study heterogeneity was tested using the χ2 test and the I2 statistic, and funnel plots were used to evaluate the publication bias. Results: A total of 11 nonrandomized trials met the inclusion criteria and were included in the meta-analysis. Our studies showed significant improvements in the BCVA (WMD = 100.55; 95% CI = 68.46 to 132.63; P < 0.01) and reduction in CMT (WMD = 0.09; 95% CI = 0.03 to 0.14; P < 0.01) after switching to aflibercept. Although a large amount of heterogeneity was detected in the CMT results among these studies, the sensitivity analyses showed the reliability and stability of our results. Conclusion and Relevance: There were significant improvements in both visual and anatomical outcomes after switching from bevacizumab or ranibizumab to aflibercept, without risk of adverse events. Thus, switching therapy may be a safe and effective treatment for patients with refractory DME.

Introduction: The surgical treatment of hallux valgus presents several techniques described in the literature. Recently, the percutaneous technique has appeared as a less invasive option in the correction of the deformity and is increasingly used by surgeons.  Methods: A meta-analysis was performed using studies discovered by the systematic review of articles included in electronic databases (Medline, Scopus, Embase and the Cochrane Library) until June 2018 (Systematic Review Registry PROSPERO: CRD42018096613). A pooling analysis was synthesized from clinical outcomes such as the visual analogue scale of pain (VAS) and AOFAS score, radiographic outcomes and evaluation of complications.  Results: Two studies, including 137 feet with a hallux valgus diagnosis were added to the analysis, comparing open surgery using the Scarf and Akin (SA) technique versus percutaneous Chevron and Akin (PECA). In the synthesis of the results, pain in the perioperative period was lower in the PECA group, with a reduction of 1.68 points in the fixed effect model (95% CI = -2.09 a -1.27, p < 0.01, i2 = 87%, t2 = 0.60). There were no differences between techniques in the radiographic results or in the risk of complications. The PECA technique demonstrated a longer radioscopy time compared with SA. Conclusion: Use of the PECA method to correct hallux valgus compared with the open SA technique demonstrated less pain in the perioperative period, a similar potential for radiographic correction and an equal risk of complications, with a longer radioscopy time.

ObjectiveTo perform a systematic review and meta-analysis of randomized controlled trials (RCTs) examining the effectiveness of continuous positive airway pressure (CPAP) in stroke patients with sleep disordered breathing (SDB).MethodsIn a systematic literature search of electronic databases (MEDLINE, Embase, and the Cochrane Library) from 1980 to November 2016, we identified RCTs that assessed CPAP compared to standard care or sham CPAP in adult patients with stroke or TIA with SDB. Mean CPAP use, odds ratios (ORs), and standardized mean differences (SMDs) were calculated. The prespecified outcomes were adherence to CPAP, neurologic improvement, adverse events, new vascular events, and death.ResultsTen RCTs (564 participants) with CPAP as intervention were included. Two studies compared CPAP with sham CPAP; 8 compared CPAP with usual care. Mean CPAP use across the trials was 4.53 hours per night (95% confidence interval [CI] 3.97–5.08). The OR of dropping out with CPAP was 1.83 (95% CI 1.05–3.21, p = 0.033). The combined analysis of the neurofunctional scales (NIH Stroke Scale and Canadian Neurological Scale) showed an overall neurofunctional improvement with CPAP (SMD 0.5406, 95% CI 0.0263–1.0548) but with a considerable heterogeneity (I2 = 78.9%, p = 0.0394) across the studies. Long-term survival was improved with CPAP in 1 trial.ConclusionCPAP use after stroke is acceptable once the treatment is tolerated. The data indicate that CPAP might be beneficial for neurologic recovery, which justifies larger RCTs.
