OBJECTIVEPredicting neurological recovery following traumatic spinal cord injury (TSCI) is a complex task considering the heterogeneous nature of injury and the inconsistency of individual studies. This study aims to summarize the current evidence on neurological recovery following TSCI by use of a meta-analytical approach, and to identify injury, treatment, and study variables with prognostic significance.METHODSA literature search in MEDLINE and EMBASE was performed, and studies reporting follow-up changes in American Spinal Injury Association (ASIA) Impairment Scale (AIS) or Frankel or ASIA motor score (AMS) scales were included in the meta-analysis...

Surgical resection is the most effective treatment for early stage lung adenocarcinoma. However, the rate of 5-year postoperative recurrence reaches 30%, Spread Through Air Spaces(STAS) is a recently described novel invasive pattern of lung cancer, According to the 2015 WHO classification. STAS is defined as"micropapillary clusters, solid nests, or single cells spreading within air spaces beyond the edge of the main tumor, However, the prognostic role of STAS in lung cancer is not known, The aim of the current study is to evaluate the association between STAS and clinical outcome of lung cancer patients after surgical resection through a meta-analysis...

Objective: Epidermal growth factor receptor (EGFR) activation was reported to upregulate programmed death-ligand 1 (PD-L1) expression in lung cancer cells and subsequently contribute to immune escape, indicating its critical role in EGFR-driven lung tumors. This study characterized PD-L1 expression in patients with surgically resected EGFR-mutant non-small cell lung cancer (NSCLC). The effect of PD-L1 expression on clinical outcomes was also investigated in advanced EGFR-mutant NSCLC treated with EGFR-tyrosine kinase inhibitors (TKIs)...

Objective Ras association domain family 1A (RASSF1A) has been regarded as a biomarker predicting the prognosis of non-small cell lung cancer (NSCLC), but previous findings are inconsistent. This meta-analysis of prospective studies aimed to assess the value of RASSF1A methylation in predicting the prognosis of NSCLC patients. Methods Studies were searched in PubMed and Web of Science. The estimates of the effects and the corresponding 95% confidence intervals (95% CIs) were used for the analyses. The overall effects of RASSF1A methylation on overall survival (OS) were estimated, after which subgroup analysis based on regions was conducted...

BACKGROUND: The predictors of outcome in patients with de novo diagnosis of heart failure (HF) with reduced ejection fraction (HFrEF) are poorly known. METHODS AND RESULTS: All consecutive HFrEF patients admitted between October 2012 and November 2017 with their first episode of HF were scheduled for an outpatient follow-up. After 3 months, patients with confirmed HFrEF underwent Iodine-123 Meta-Iodobenzylguanidine imaging. We defined three study endpoints: HF rehospitalization, cardiac death and all-cause death...

Eyes absent homolog 2 (EYA2), a transcriptional activator, is pivotal for organ development, but aberrant regulation of EYA2 has been reported in multiple human tumors. However, the role of EYA2 in breast cancer is still lack of full understanding. To explore the biological significance of EYA2 in breast cancer, we conducted data analysis on public breast cancer datasets, and performed immunohistochemistry (IHC) analysis, colony-forming unit assays, EdU assay, western blotting, and immunofluorescence (IF). Meta-analysis showed that EYA2 mRNA expression was correlated with tumor grade, the status of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2)...

Cyclooxygenase-2 (COX-2), a key enzyme in arachidonic acid metabolism, is involved in several cancers, including osteosarcoma. The prognostic significance of COX-2 in osteosarcoma remains controversial. This study was to analyze the potential clinical and prognostic effects of COX-2 protein expression in patients with osteosarcoma. Eligible articles were searched via online databases. The combined odds ratios (ORs) or hazard ratios (HRs) with their 95% confidence intervals (95% CIs) were calculated using the random-effects model...

BACKGROUND: High-throughput non-invasive prenatal testing (NIPT) for fetal Rhesus D (RhD) status could avoid unnecessary treatment with anti-D immunoglobulin for RhD-negative women found to be carrying an RhD-negative fetus. We aimed to assess the diagnostic accuracy of high-throughput NIPT for fetal RhD status in RhD-negative women not known to be sensitized to the RhD antigen, by performing a systematic review and meta-analysis. METHODS: Prospective cohort studies of high-throughput NIPT used to determine fetal RhD status were included...

BACKGROUND: To date, little is known about the characteristics of highly cited studies in hand surgery compared with other orthopaedic subspecialties. We aimed to assess the position of hand surgery within the orthopedic surgery literature. METHODS: We conducted a bibliographic analysis using the Web of Science database to review 1,568 articles published between January 2012 and December 2012 in 4 relevant general orthopedic and 2 hand surgery journals. We used the number of citations within 3 years of publication to measure the impact of each paper...

The aim of this meta-analysis is to evaluate myeloblastosis (MYB) as a prognostic marker for patients with adenoid cystic carcinoma (ACC) with respect to MYB gene fusion, MYB protein expression, and tumor sites. We comprehensively searched PubMed, Embase, Web of Science, and Cochrane libraries. Ten studies concerning the prognostic comparisons between MYB positivity and negativity were included. The combined positive rates of MYB gene fusion and protein expression were 57.2% and 62.3%, respectively. Overall, no significant prognostic differences were observed between MYB-positive and MYB-negative ACCs...
