The efficacy and safety of glucokinase activators for the treatment of type-2 diabetes mellitus: A protocol for systematic review and meta-analysis

Background:Glucokinase activators are a novel family of glucose-lowering agents used for the treatment of type-2 diabetes mellitus (T2DM). Glucokinase activators blind to GK activate the enzyme allosterically. Treatment with different GKAs has been shown to reduce fasting and postprandial glucose in patients with type 2 diabetes. We compared the efficacy/safety of glucokinase activators in T2DM patients through a meta-analysis.Methods:We searched PubMed, Excerpt Medica Database, and Cochrane Central Register of Controlled Trials databases for articles published before December 30, 2020. Two independent reviewers extracted the information from article. The quality of articles were assessed by 2 independent reviewers using the 5 items of scale proposed by Jadad. We computed the weighted mean difference and 95% confidence interval (CI) for a change from baseline to the study endpoint for glucokinase activators vs placebo. Egger test and Begg test were used to assess the possible publication bias caused by the tendency of published studies to be positive.Results:The present meta-analysis will compare the efficacy and safety of glucokinase activators and placebo for the treatment of T2DM.Conclusions:This meta-analysis will provide advanced evidence on the efficacy and safety of glucokinase activators for the treatment of T2DM.Ethics and dissemination:Ethical approval and patient consent are not required because this study is a literature-based study. This systematic review and meta-analysis will be published in a peer-reviewed journalPROSPERO registration number:CRD42021220364.     

The necessity or not of the addition of fusion to decompression for lumbar degenerative spondylolisthesis patients: A PRISMA compliant meta-analysis

Background:The new emerging application of decompression combined with fusion comes with a concern of cost performance, however, it is a lack of big data support. We aimed to evaluate the necessity or not of the addition of fusion for decompression in patients with lumbar degenerative spondylolisthesis.Methods:Potential studies were selected from PubMed, Web of Science, and Cochrane Library, and gray relevant studies were manually searched. We set the searching time spanning from the creating date of electronic engines to August 2020. STATA version 11.0 was exerted to process the pooled data.Results:Six RCTs were included in this study. A total of 650 patients were divided into 275 in the decompression group and 375 in the fusion group. No statistic differences were found in the visual analog scales (VAS) score for low back pain (weighted mean difference [WMD], –0.045; 95% confidence interval [CI], –1.259–1.169; P = .942) and leg pain (WMD, 0.075; 95% CI, –1.201–1.35; P = .908), Oswestry Disability Index (ODI) score (WMD, 1.489; 95% CI, –7.232–10.211; P = .738), European Quality of Life-5 Dimensions (EQ-5D) score (WMD, 0.03; 95% CI, –0.05–0.12; P = .43), Odom classification (OR, 0.353; 95% CI 0.113–1.099; P = .072), postoperative complications (OR, 0.437; 95% CI, 0.065–2.949; P = .395), secondary operation (OR, 2.541; 95% CI 0.897–7.198; P = .079), and postoperative degenerative spondylolisthesis (OR = 8.59, P = .27). Subgroup analysis of VAS score on low back pain (OR = 0.77, 95% CI, 0.36–1.65; P = .50) was demonstrated as no significant difference as well.Conclusion:The overall efficacy of the decompression combined with fusion is not revealed to be superior to decompression alone. At the same time, more evidence-based performance is needed to supplement this opinion.     

Differences in clinical characteristics and liver injury between suspected and confirmed COVID-19 patients in Jingzhou,Hubei Province of China

To evaluate the clinical characteristics and liver injury in coronavirus disease 2019 (COVID-19) patients, and analyze the differences between suspected and confirmed COVID-19 patients, this retrospective study was performed on 157 COVID-19 patients and 93 suspected patients who were ultimately excluded from COVID-19 (control patients). Differences in clinical characteristics and liver injury between suspected and confirmed COVID-19 patients were analyzed. Age, male sex, fever, chest tightness and dyspnea were related to the severity of COVID-19. C-reactive protein (CRP) and D-dimer may be predictors of the severity of COVID-19. Computed tomography (CT) played an important role in the screening of COVID-19 and the evaluation of disease severity. Multiple factors may cause liver injury in COVID-19 patients. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be more likely to cause liver injury than common respiratory infectious diseases. Age, temperature (T), white blood cell (WBC), lymphocytes (LY), hematocrit (HCT), CRP, and finger pulse oxygen saturation (SpO₂₎ may correlate with liver function impairment and may predict the occurrence and severity of liver function impairment. Some therapeutic drugs (like glucocorticoid) may be involved in the liver function impairment of COVID-19 patients. Most liver function indices improved significantly after active treatment. Although COVID-19 and other common respiratory infectious diseases share some clinical characteristics, COVID-19 has its own characteristics.     

The effect of remote peer support on stigma in patients after breast cancer surgery during the COVID-19 pandemic: A protocol for systematic review and meta-analysis

Background:Patients after breast cancer surgery have a high sense of stigma due to the formation of surgical scars, loss of breast shape or other reasons, leading to anxiety, depression, and other adverse mental health problems, thus reducing their quality of life. Remote peer support intervention based on telephone, internet or email is low-cost and easy to spread, and protects patients’ privacy, solves the barriers to access that many patients face when attending face-to-face programs. Therefore, remote peer support may be an effective way to reduce stigma and improve mental health in patients after breast cancer surgery during the coronavirus disease 2019 (COVID-19) pandemic.Methods:Eight databases (PubMed, Embase, Cochrane Library, CNKI, PsycNET, MEDLINE, Psychology & Behavioral Sciences Collection and Web of Science) will be used to select eligible studies that were published from inception to May, 2021. The eligible studies will be screened, extracted and then the methodological quality will be evaluated independently by 2 reviewers. Review manager software version 5.3 software and Stata version 14.0 software will be used for meta-analysis.Results:The results of this study will show the effect of remote peer support on stigma, depression and anxiety in patients after breast cancer surgery during the COVID-19 pandemic and will be submitted to a peer-reviewed journal for publication.Conclusion:The results of this study will provide evidence for the effectiveness of remote peer support in patients after breast cancer surgery during the COVID-19 pandemic.PROSPERO registration number:CRD42021255971.     

Porcine germline genome engineering

Germline editing, the process by which the genome of an individual is edited in such a way that the change is heritable, has been applied to a wide variety of animals [D. A. Sorrell, A. F. Kolb, Biotechnol. Adv. 23, 431–469 (2005); D. Baltimore et al., Science 348, 36–38 (2015)]. Because of its relevancy in agricultural and biomedical research, the pig genome has been extensively modified using a multitude of technologies [K. Lee, K. Farrell, K. Uh, Reprod. Fertil. Dev. 32, 40–49 (2019); C. Proudfoot, S. Lillico, C. Tait-Burkard, Anim. Front. 9, 6–12 (2019)]. In this perspective, we will focus on using pigs as the model system to review the current methodologies, applications, and challenges of mammalian germline genome editing. We will also discuss the broad implications of animal germline editing and its clinical potential.

Regular arrangement of collecting venules under endoscopy for predicting a Helicobacter pylori-negative stomach: A systematic review and meta-analysis

Background and aimsThe regular arrangement of collecting venules (RAC) refers to the appearance of multiple regular tiny veins in the body of the stomach and is considered to be very effective for identifying gastric mucosa with non-Helicobacter pylori infection. This meta-analysis was conducted to systematically evaluate the value of the sign in predicting a Helicobacter pylori-negative stomach and the relevant factors that may affect the performance of this prediction.MethodsTwo biomedical databases (PubMed and EMBASE) were systematically searched through April 20, 2020. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) and area under the SROC curve (AUC) were calculated.ResultsFourteen articles with 4070 patients were included. The pooled sensitivity, specificity, PLR, NLR, DOR and AUC for the RAC in predicting non-Hp infection were 0.80 (0.67–0.89), 0.97 (0.93–0.98), 24.8 (12.2–50.8), 0.21 (0.12–0.36), 120 (47–301) and 0.97 (0.19–1.00), respectively.ConclusionsThe RAC is a valuable endoscopic feature for the prediction of patients without Hp infection.
