ObjectiveEvaluating the clinical efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) for osteoporotic vertebral compressive fracture (OVCF). MethodsPatients with OVCF were retrospectively analyzed from Feb. 2008 to Feb. 2013 in Department of Orthopaedics, Tianjin Medical University General Hospital. Patients were divided into the PVP group and the PKP group. The VAS, vertebral kyphosis angle, vertebral height and bone cement leakage of both groups were compared, and the SPSS13.0 software was used for data analysis. ResultsA total of 55 patients were included. Of which, 25 patients were in the PVP group and 30 patients were in the PKP group. All patients were followed up from 5 to 20 months, with an average time of 15.5 months. The VAS scores in both groups were all improved after the operation (P<0.05), but no significant difference was found between both groups. The vertebral kyphosis angle in both groups were improved after the operation (P<0.05), and the PKP group was better than the PVP group. Six patients in the PVP group occurred the leakage of bone cement, and 4 patients in the PKP group. Five patients in the PVP groups occurred vertebral fracture again, while 7 patients in the PKP group. ConclusionUsing PVP and PKP for the treatment of OVCF can quickly relieve pain and increase the stability of the vertebral body. PKP can restore vertebral body height better and reduce the incidence of cement leakage.
ObjectivesTo systematically review the association between body mass index (BMI) and mortality of chronic obstructive pulmonary disease (COPD).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect cohort studies on the association between BMI and mortality of COPD from inception to February, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 14 cohort studies involving 494 060 COPD patients were included. The results of meta-analysis showed that, compared with patients having a normal weight, underweight individuals were associated with higher mortality (RR=1.40, 95%CI 1.15 to 1.71, P=0.000 8), whereas overweight (RR=0.65, 95%CI 0.54 to 0.79, P<0.000 1) and obese (RR=0.37, 95%CI 0.20 to 0.67, P=0.001) patients were associated with lower mortality.ConclusionsCurrent evidence shows that underweight is associated with a higher risk of all-cause mortality among patients with COPD, whereas overweight and obese are associated with lower risk of all-cause mortality in these patients. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To systematically review the efficacy of robotic, laparoscopic-assisted, and open total mesorectal excision (TME) for the treatment of rectal cancer. Methods The PubMed, EMbase, The Cochrane Library, and ClinicalTrials.gov databases were electronically searched to identify cohort studies on robotic, laparoscopic-assisted, and open TME for rectal cancer published from January 2016 to January 2022. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Subsequently, network meta-analysis was performed using RevMan 5.4 software and R software. Results A total of 24 studies involving 12 348 patients were included. The results indicated that among the three types of surgical procedures, robotic TME showed the best outcomes by shortening the length of hospital stay, reducing the incidence of postoperative anastomotic fistula and intestinal obstruction, and lowering the overall postoperative complication rate. However, differences in the number of dissected peritumoural lymph nodes were not statistically significant. Conclusion Robotic TME shows better outcomes in terms of the radicality of excision and postoperative short-term outcomes in the treatment of rectal cancer. However, clinicians should consider the patients’ actual condition for the selection of surgical methods to achieve individualised treatment for patients with rectal cancer.
ObjectiveTo systematically review the short term and long term efficacy of early surgery for infective endocarditis (IE) patients. MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases for cohort studies concerning the efficacy of early surgery for IE patients from inception to October 2014. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsSixteen cohort studies including 8 141 patients were included. The results of meta-analysis showed that early surgery could reduce the short term mortality (OR=0.57, 95%CI 0.42 to 0.77, P=0.000 4) and long term mortality (OR=0.57, 95%CI 0.43 to 0.77, P=0.000 7) in IE patients. Subgroup analysis showed that early surgery could significantly reduce the short term mortality and long term mortality in patients with native valve endocarditis (NVE). ConclusionEarly surgery can reduce IE patients' short term mortality and long term mortality. Due to the limited quality and quantity of the included studies, more large-scale high-quality studies are needed to verify the above conclusion.
Objectives To systematically review the efficacy of conservative treatment and open reduction with internal fixation for multiple rib fractures. Methods We searched WanFang Data, CNKI, VIP, PubMed, EMbase, The Cochrane Library and Web of Science from inception to December 2017 to collect studies on conservative treatment and open reduction with internal fixation for multiple rib fractures. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. RevMan 5.3 software was used for meta-analysis. Results A total of 16 studies were included, involving 1 374 patients, 723 patients in the surgical group and 651 patients in the conservative group. The meta-analysis showed that the length of stay in the ICU (MD=–3.41, 95%CI –4.92 to –2.43, P<0.000 01), total length of stay (MD=–7.60, 95 %CI–10.67 to–4.53,P<0.000 01), incidence of pulmonary arylene (RR=0.40, 95%CI 0.29 to 0.54,P<0.000 01), incidence of lung infections (RR=0.43, 95%CI 0.30 to 0.61,P<0.000 01), and incidence of chest wall malformation (RR=0.05, 95%CI 0.03 to 0.11,P<0. 0.000 01) in the surgical group were superior to the conservative group. Conclusions Compared with conservative treatment, open reduction with internal fixation can significantly improve the recovery time of patients with multiple rib fractures, reduce hospitalization time, the incidence of perioperative complications, and significantly enhance the prognosis of patients, which is more conducive to the rehabilitation of patients.
Objective To systematically evaluate the correlation between coffee and risk of endometrial cancer. Methods Such databases as CBM, CNKI, WanFang data, PubMed, EMbase and The Cochrane Library (Issue 5, 2012) were searched to collect the prospective cohort studies about correlation between coffee and endometrial cancer. The retrieval time was by the end of May 2012, and the references of the included literature were also retrieved. Two evaluators independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the statistical analysis was conducted by using Stata 12.0 software. Results A total of 10 cohort studies involving 4 484 patients with endometrial cancer were included. The results of meta-analysis showed that, compared with the women who didn’t drink coffee or drank in the lowest dose, the women who drank coffee in the highest dose had a decreased risk of endometrial cancer (RR=0.69, 95%CI 0.62 to 0.78), same as the women who drank coffee frequently (RR=0.83, 95%CI 0.77 to 0.89). The results of dose-response analysis revealed that, when there was an increase of 2 more cups of coffee per day, there was the risk of endometrial cancer decreased by 12%. Conclusion Drinking coffee frequently (more than 2 cups per day) can decrease the risk of endometrial cancer which can be significantly decreased when drinking in a big dose (more than 5 cups per day).
Objectives To systematically review the influence of positive margin on outcome after partial nephrectomy (PN). Methods CCRCT, PubMed, EMbase, Sinomed, WanFang Data and CNKI databases were electronically searched to collect clinical studies on influence of positive margin on outcome after PN from inception to December 31st, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.4 software. Results A total of 22 cohort studies involving 20 822 patients were included. The results of meta-analysis showed that positive margin after PN could increase the rate of postoperative local recurrence (OR=4.18, 95%CI 2.88 to 6.05, P<0.000 01), distant metastasis (OR=5.28, 95%CI 2.84 to 9.81,P<0.000 01) and total mortality (OR=1.54, 95%CI 1.19 to 1.99,P=0.0010). However, there were no differences on overall survival (OR=0.64, 95% CI 0.34 to 1.19, P=0.16), distant metastasis free survival (OR=0.70, 95%CI 0.26 to 1.84, P=0.46), cancer specific survival (OR=0.43, 95% CI 0.06 to 3.01, P=0.40) and disease-free survival (OR=0.81, 95%CI 0.35 to 1.85, P=0.61) between two groups. Conclusions Current evidence suggests that positive margin after PN may be associated with tumor progression, however, it may not affect patient survival. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo systematically review the prognostic efficacy and safety of patients with ovarian cancer treated with systemic lymphadenectomy (SL). MethodsPubMed, The Cochrane Library, Web of Science, CNKI, WanFang Data, and CBM databases were electronically searched to collect randomized controlled trials (RCTs) and cohort studies on the prognostic outcomes of patients with ovarian cancer treated with SL from inception to December 16th, 2020. Six reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.4 software. ResultsA total of 5 RCTs and 23 cohort studies involving 6 166 patients were included. The results of meta-analysis showed that there were no significant differences in the 3-year survival rate, 5-year survival rate, 3-year progression-free survival rate, and 5-year progression-free survival rate between SL group and the no systemic lymphadenectomy (NSL) group. The results of the subgroup analysis showed that pelvic and para-aortic lymph node dissection combined with large omentum resection had a better prognosis for patients. ConclusionsCurrent evidence shows that SL has no significant efficacy on survival and progression-free survival in patients with ovarian cancer. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
ObjectiveTo systematically review the association between acid suppressive drug use and fracture risk in children and adolescents. MethodsThe PubMed, Web of Science, EMbase, Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect observational studies on the association between acid suppressive drug use and fracture risk in children and adolescents from inception to October 1, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using R4.1.2 software. ResultsA total of 6 studies involving 1 886 423 children and adolescents were included. Meta-analysis results showed that the use of proton pump inhibitors (PPIs) increased the risk of fracture (RR=1.19, 95%CI 1.10 to 1.29, P<0.01), whereas the use of histamine H2 receptor antagonists (H2RAs) did not increase the risk of fracture (P>0.05). Subgroup analysis showed that PPIs use increased risk of fracture in the lower limb and other sites (P<0.05). ConclusionCurrent evidence shows that PPIs can increase fracture risk in children and adolescents, but no association has been found between the use of H2RAs and increased fracture risk in this group. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
