RESUMEN

Objective To investigate the prognostic value of the platelet-lymphocyte ratio (PLR) in non-small cell lung cancer patients treated with PD-1/PD-L1 inhibitors. Methods PubMed, EMBASE, Web of Science, Medline, Cochrane Library, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, VIP, WanFang and other databases were searched online for eligible studies about evaluating the relation between PLR and the prognosis of NSCLC patients treated with PD-1/PD-L1 inhibitors from the establishment of database to April 2020. The relevant data of literatures that met the inclusion criteria were extracted. Pooled estimates of HR and 95%CI were calculated using Stata 15.0. Results We included six studies involving 551 patients. Elevated PLR was associated with worse OS and PFS of NSCLC patients treated with PD-1/PD-L1 inhibitors. The subgroup analysis of OS showed the prognostic value of high PLR in Caucasian race, cutoff value ≤169.05, PLR cutoff value determination according to previous literature and multi-center retrospective study (P < 0.05). Subgroup analysis of PFS showed the prognostic value of high PLR in East Asian race, cutoff value ≤169.05, PLR cutoff value determination according to previous literature and single-center retrospective study (P < 0.05). Conclusion Among NSCLC patients treated with PD-1/PD-L1 inhibitors, elevated blood PLR is associated with shorter OS and PFS, indicating that it may be a potential biomarker for PD-1/PD-L1 treatment on NSCLC patients.

RESUMEN

ObjectiveTo systematically evaluate the association between vitamin D level and nonalcoholic fatty liver disease (NAFLD) in children and adolescents. MethodsRelated English and Chinese databases, including PubMed, Cochrane Library, Embase, CNKI, CBM, Wanfang Data, and VIP, were searched for studies on the association between vitamin D level and NAFLD in children and adolescents published up to August 2020. Newcastle-Ottawa Scale (NOS) was used to evaluate quality of studies, and RevMan 5.3 software was used for data analysis. ResultsA total of 10 articles were included in the meta-analysis, with 622 patients in the NAFLD group and 1608 in the healthy control group. All 10 articles had an NOS score of ≥6. A pooled analysis of the 10 articles was performed using a random effects model (I2=97%, P<0.05). The NAFLD group had a significantly lower serum 25(OH) D level than the healthy control group (standardized mean difference=-1.40, 95% confidence interval: -2.07 to -0.72). ConclusionThere is a significant reduction in serum vitamin D level in children and adolescents with NAFLD, which may be associated with the progression and severity of NAFLD.
