The clinical course and prognostic factors of severe COVID-19 in Wuhan,China: A retrospective case-control study

With the surge of newly diagnosed and severe cases of coronavirus disease 2019 (COVID-19), the death toll is mounting, this study is aimed to explore the prognostic factors of severe COVID-19. This retrospective study included 122 inpatients diagnosed with COVID-19 from January 13 to February 25, 2020. Univariate and multivariate analysis were used to identity the risk factors, receiver operating characteristics curve (ROC) analysis was used for risk stratification. The baseline neutrophil-to-lymphocyte ratio (NLR) (OR = 1.171, 95%CI = 1.049–1.306, P = .005) and Lactate dehydrogenase (LDH) (OR = 1.007, 95%CI = 1.002–1.011, P = .004) were identified as the independent risk factors for severe COVID-19 conditions, and the NLR-LDH grading system was developed to perform risk stratification. The baseline C-reactive protein (CRP) (OR = 1.019, 95%CI = 1.004–1.306, P = .016) and B-type natriuretic peptide (BNP) (OR = 1.018, 95%CI = 1.004–1.035, P = .007) were identified as the independent predictors for disease progression of severe patients. Accordingly, The NLR-LDH grading system was a useful prognostic tool for the early detection of severe COVID-19. And in the severe patients, CRP and BNP seemed to be helpful for predicting the disease progression or death.     

Predictors of prolonged mechanical ventilation identified at an emergency visit for elderly people: A retrospective cohort study

The aim of this study was to determine the factors that are associated with prolonged mechanical ventilation in elderly patients.Retrospective cohort studySingle tertiary hospital in JapanWe retrospectively identified 228 patients aged 75 years or older who were admitted to a single tertiary care center in Japan between January 1, 2014 and December 31, 2017 because of endogenous diseases and underwent mechanical ventilation.The primary outcome was extubation difficulty, which was defined as the need for mechanical ventilation for more than 14 days after intubation, reintubation within 72 hours after extubation, tracheotomy or extubation, or death within 14 days after intubation.A multivariate analysis showed that age (odds ratio [OR] = 0.95; 95% confidence interval [CI] = 0.66–1.38; P = .80), gender (OR = 0.56; 95%CI = 0.27–1.17; P = .13), body mass index (BMI) (OR = 1.05; 95%CI = 0.98–1.14; P = .16), smoking history (OR = 0.64; 95%CI = 0.29–1.41; P = .27), Activities of daily living (ADL) (OR = 0.95; 95%CI = 0.49–1.83; P = .87), and modified acute physiology and chronic health evaluation (APACHE) II score (OR = 1.02; 95%CI = 0.95–1.09; P = .61) were not statistically significantly different. However, there were statistically significant differences in extubation difficulty between patients with diabetes mellitus (OR = 2.3; 95%CI = 1.01–5.12; P = .04) and those with cardiovascular disease diagnosis on admission (OR = 0.31; 95%CI = 0.1–0.97; P = .04).Diabetes mellitus and cardiovascular disease diagnosis on admission were factors that were associated with prolonged mechanical ventilation in the elderly. The results of this study may help to support shared decision making with patients or surrogate decision makers at the start of intensive care in the elderly.     

No evidence of tocilizumab treatment efficacy for severe to critical SARS-CoV2 infected patients: Results from a retrospective controlled multicenter study

To assess tocilizumab (TCZ) efficacy associated to standard of care (SOC) compared to SOC alone in severe coronavirus associated disease 2019 (COVID-19) patients. In a matched case-control study from 3 French Hospital COVID-19 Departments, 27 patients with severe COVID-19 treated with TCZ and SOC were matched for baseline epidemiological and clinical features and compared to 27 severe COVID-19 patients treated with SOC alone. Baseline characteristics of the study population were comparable between groups. Eleven patients (20%) died. TCZ was not associated with clinical improvement as compared to SOC regarding oxygen-free status (44% vs 63%) and death (18.5% vs 22%), despite a higher decrease of the C-reactive protein at Day 7 (10.7 vs 52 mg/L; P < 10⁻³). Compared to the 43 patients alive at the end-of follow-up, patients who died were older (78 vs 64 years; P < 10⁻³), with 82% of them older than 72 years vs only 23% of live patients (P < 10⁻³). Age (OR = 1.15; 95%CI = 1.04–1.3; P = .008) and age over 72 years (OR) = 14.85; 95%CI = 2.7–80; P = .002) were independently associated with mortality. TCZ in addition to SOC for severe COVID-19 patients did not reduce mortality, subsequent need for invasive mechanical ventilation nor did it shorten the time of oxygen support, despite better control of the inflammatory response. More powerful and randomized controlled trials are warranted to determine if TCZ is effective in the management of COVID-19.     

Correlation between lncRNA SNHG16 gene polymorphism and its interaction with environmental factors and susceptibility to colorectal cancer

Objective:To study the relationship between long-chain non-coding RNA small nucleolar RNA host gene 16 (lncRNA SNHG16) polymorphisms and its interaction with environmental factors and susceptibility to colorectal cancer (CRC).Methods:Sanger sequencing was used to analyze genotypes of lncRNA SNHG16 gene rs7353, rs8038, and rs15278 sites. Multifactor dimensionality reduction was used to analyze interactions between lncRNA SNHG16 gene rs7353, rs8038, rs15278 sites, and environmental factors. Haploview 4.1 software was used to analyze linkage disequilibrium of lncRNA SNHG16 gene rs7353, rs8038, and rs15278 sites. Quantitative real-time polymerase chain reaction was used to analyze plasma lncRNA SNHG16 levels of CRC patients and control subjects.Results:Variation of the lncRNA SNHG16 gene rs7353 site A>G variation was associated with decreased CRC susceptibility (Odds ratio [OR] = 0.50, 95% confidence interval [CI]: 0.40–0.62, P < .01). The rs8038 site G>A and rs15278 site A>G variation were associated with increased CRC susceptibility (OR = 1.87, 95% CI: 1.47–2.36, P < .01). The rs15278 site G>A variation was associated with increased CRC susceptibility (OR = 2.24, 95% CI: 1.61–3.11, P < .01). Interaction combinations featuring age, rs7353, rs8038, and rs15278 single nucleotide polymorphism are 13.53 times more susceptible to CRC than other interactions (95% CI: 9.43–19.41, P < .01). The rs15278, rs8038, and rs7353 site AGA haplotypes were significantly associated with a decreased CRC risk (OR = 0.65, 95% CI: 0.48–0.88, P = .01), AAG haplotypes were significantly associated with an increased CRC risk (OR = 2.00, 95% CI: 1.27–3.17, P < .01). High lncRNA SNHG16 expression was associated with tumor progression in CRC patients (χ² = 8.85, P = .03). The rs7353 site A>G variation caused a significant decrease in plasma lncRNA SNHG16 level (P < .01), while the rs8038 site G>A variation and rs15278 site A>G variation resulted in increased plasma lncRNA SNHG16 levels.Conclusion:Polymorphisms of lncRNA SNHG16 gene rs7353, rs8038, rs15278 loci and their interaction with age are significantly associated with CRC susceptibility.     

The Role of TP53 Gene Codon 72 Polymorphism in Leukemia: A PRISMA-Compliant Systematic Review and Meta-Analysis

The purpose of this meta-analysis was aimed to evaluate the association of tumor protein p53 (TP53) gene codon 72 polymorphism with leukemia susceptibility.We searched PubMed to identify relevant studies, and 16 case-control studies from 14 published articles were identified as eligible studies, including 2062 leukemia patients and 5826 controls. After extracting data, odds ratio (OR) with the corresponding 95% confidence interval (95%CI) was applied to assess the association between TP53 codon 72 polymorphism and leukemia susceptibility. The meta-analysis was performed with the Comprehensive Meta-Analysis software, version 2.2.Overall, no significant association between TP53 codon 72 polymorphism and leukemia susceptibility was found in this meta-analysis (Pro vs Arg: OR = 1.05, 95%CI = 0.90–1.21; Pro/Pro vs Arg/Arg: OR = 1.13, 95%CI = 0.84–1.52; Arg/Pro vs Arg/Arg: OR = 0.94, 95%CI = 0.76–1.15; [Pro/Pro + Arg/Pro] vs Arg/Arg: OR = 0.99, 95%CI = 0.80–1.21; Pro/Pro vs [Arg/Arg + Arg/Pro]: OR = 1.19, 95%CI = 0.93–1.51). Similar results were also found in subgroup analysis by ethnicity, source of controls, and types of leukemia (either acute myeloid leukemia or acute lymphocytic leukemia).Our meta-analysis demonstrates that TP53 codon 72 polymorphism may not be a risk factor for acute leukemia; however, due to the limitations of this study, it should be verified in future studies.     

Genetic association between bone mineral density and the fracture of distal radius: A case-control study

Low bone mineral density (BMD) was significantly related to the fracture of distal radius. Serum brain-derived neurotrophic factor (BDNF) level was closely related to BMD in spine and osteoporotic fractures. In this study, we aimed to explore the association of BDNF polymorphisms (rs6265 and rs7124442) with BMD and the fracture of distal radius.This retrospective study included 152 patients with distal radius fractures and 148 healthy controls. BDNF polymorphisms were detected via TaqMan allelic discrimination assay. BMD was evaluated through X-ray. Difference in features between cases and controls were compared adopting Chi-square test or t test. The associations of BDNF polymorphisms with fracture risk of distal radius and BMD were assessed employing χ² test and expressed by odd ratios (ORs) with 95% confidence intervals (95% CIs).BMD was significantly decreased in patients with the fracture of distal radius than in healthy controls. The polymorphism rs6265 significantly increased the risk of distal radius fracture (adjustment: GA: OR = 1.724, 95%CI = 1.003 –2.951, P = .049; GG: OR = 2.415, 95%CI = 1.0219 –3.674, P = .005). Moreover, rs6265 genotypes GA (OR = 4.326, 95%CI = 1.725 –11.896, P = .003) and GG (OR = 13.285, 95%CI = 3.659 –51.072, P = .001) significantly increased BMD reduction. However, BDNF polymorphism rs7124442 had no obvious correlation with BMD or fracture risk.BMD was associated with BDNF rs6265 polymorphism. BDNF polymorphism rs6265 could elevate the risk of osteoporosis and distal radius fracture.     

Prevalence and risk factors of hypertension among Hui population in China: A systematic review and meta-analysis based on 30,565 study participants

Background:Hypertension (HTN) has been considered as a health concern in developing countries. And Hui is a minority group with a large population in China. Its genetic background, inadequate access to health services, eating habits, religious belief, ethnic customs, and other factors differ from that of other ethnic groups, which may influence the prevalence of HTN. However, there is no current meta-analysis on the prevalence and risk factors of HTN among Hui population. Thus we conducted a systematic review aiming to estimate the pooled prevalence and risk factors of HTN among Hui population.Methods:PubMed, The Cochrane library, Web of science, CINAHL Complete, Weipu Database (VIP), China Knowledge Resource Integrated Database (CNKI), Wanfang Database, and SinoMed were systematically searched from inception to February 28, 2020 with publication language restricted to English and Chinese. We included cross-sectional, case–control, or cohort studies that focused on prevalence and risk factors of HTN among Hui population. Two investigators independently assessed the risk of bias of the studies included in the review using tools developed by JBI. Meta-analysis was conducted using Stata 12.0 software package.Results:Twenty-three studies were identified with a total of 30,565 study participants. The overall pooled prevalence of HTN was 28% (95% confidence interval [CI]: 24%–32%, I² = 98.8%, P < .001). Stratified by gender, the pooled prevalence of HTN in Hui was 26% (95%CI: 20%–33%, I² = 97.6%, P < .001) for males and 30% (95%CI: 23%–37%, I² = 98.3%, P < .001) for females. Pooled prevalence of HTN in Hui was 2% (95%CI: 2%–6%, I² = 70.6%, P = .065), 10% (95%CI: 3%–17%, I² = 83.7%, P < .001), 22% (95%CI: 12%–32%, I² = 87.9%, P < .001), 37% (95%CI: 20%–53%, I² = 94.0%, P < .001), 39% (95%CI: 24%–54%, I² = 97.7%, P < .001) and 42% (95%CI: 29%–56%, I² = 95.6%, P < .001) for those aged 18 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, and ≥70 years, respectively. Pooled prevalence of HTN in Hui was 22% (95%CI: 14%–29%, I² = 97.9%, P < .001) in urban areas and 23% (95%CI: 16%–30%, I² = 95.8%, P < .001) in rural areas. Daily salt intake (odd ratio [OR] = 3.94, 95%CI: 3.03–5.13, I² = 90.2%, P < 001), family history (OR = 3.50, 95%CI: 2.60–4.71, I² = 95.3%, P < .001), smoking (OR = 1.84, 95%CI: 1.61–2.09, I² = 59.6%, P < .001), drinking (OR = 1.74, 95%CI: 1.26–2.39, I² = 95.3%, P = .001), weekly meat intake (OR = 1.92, 95%CI: 1.04–3.54, I² = 96.5%, P = .036), body mass index (OR = 2.20, 95%CI: 1.81–2.66, I² = 91.3%, P < .001), and areas (OR = 1.29, 95%CI: 1.10–1.51, I² = 81.5%, P = .001) were risk factors of HTN in Hui, while physical exercise (OR = 0.76, 95%CI: 0.66–0.88, I² = 62.7%, P < .001) was protective factor.Conclusions:The pooled prevalence of HTN among Hui people was 28%, daily salt intake, family history, drinking, smoking, weekly meat intake, body mass index, areas, and physical exercise were all risk factors for HTN among Hui population. Early screening and treatment of HTN among Hui population should be given due attention.     

Development and validation of a prediction model for malignant pulmonary nodules: A cohort study

This study is to develop and validate a preoperative prediction model for malignancy of solitary pulmonary nodules. Data from 409 patients who underwent solitary pulmonary nodule resection at the First Affiliated Hospital of Nanjing Medical University, China between June 2018 and December 2020 were retrospectively collected. Then, the patients were nonrandomly split into a training cohort and a validation cohort. Clinical features, imaging parameters and laboratory data were then collected. Logistic regression analysis was used to develop a prediction model to identify variables significantly associated with malignant pulmonary nodules (MPNs) that were then included in the nomogram. We evaluated the discrimination and calibration ability of the nomogram by concordance index and calibration plot, respectively. MPNs were confirmed in 215 (52.6%) patients by a pathological examination. Multivariate logistic regression analysis identified 6 risk factors independently associated with MPN: gender (female, odds ratio [OR] = 2.487; 95% confidence interval [CI]: 1.313–4.711; P = .005), location of nodule (upper lobe of lung, OR = 1.126; 95%CI: 1.054–1.204; P < .001), density of nodule (pure ground glass, OR = 4.899; 95%CI: 2.572–9.716; P < .001; part-solid nodules, OR = 6.096; 95%CI: 3.153–14.186; P < .001), nodule size (OR = 1.193; 95%CI: 1.107–1.290; P < .001), GAGE7 (OR = 1.954; 95%CI: 1.054–3.624; P = .033), and GBU4–5 (OR = 2.576; 95%CI: 1.380–4.806; P = .003). The concordance index was 0.86 (95%CI: 0.83–0.91) and 0.88 (95%CI: 0.84–0.94) in the training and validation cohorts, respectively. The calibration curves showed good agreement between the predicted risk by the nomogram and real outcomes. We have developed and validated a preoperative prediction model for MPNs. The model could aid physicians in clinical treatment decision making.     

Clinicopathological and prognostic significance of NM23 expression in patients with non-small cell lung cancer: A systematic review and meta-analysis

Background:There is a heated debate on the clinicopathological features and prognostic significance with non-metastasis 23 (NM23) expression in patients with non-small cell lung cancer (NSCLC). Thus, we conducted this meta-analysis to evaluate the clinicopathological features and prognostic significance of NM23 for NSCLC patients.Methods:Pubmed, Embase, and Web of Science were exhaustively searched to identify relevant studies published prior to March, 2020. Odds radios (ORs) and hazard radios with 95% confidence intervals (CIs) were calculated to summarize the statistics of clinicopathological and prognostic assessments. Q-test and I²-statistic were utilized to assess heterogeneity across the included studies. We also performed subgroup analyses and meta-regression analyses to identify the source of heterogeneity. Publication bias was detected by Begg and Egger tests. Sensitivity analysis was used to value the stability of our results. All the data were analyzed using statistical packages implemented in R version 4.0.5.Results:Data from a total of 3170 patients from 36 studies were extracted. The meta-analysis revealed that low expression of NM23 was correlated with higher risk of NSCLC (OR = 4.35; 95% CI: 2.76–6.85; P < .01), poorer tumor node metastasis (TNM) staging (OR = 1.39; 95% CI: 1.01–1.90; P = .04), poorer differentiation degree (OR = 1.37; 95% CI: 1.01–1.86; P = .04), positive lymph node metastasis (OR = 1.83; 95% CI: 1.22–2.74; P < .01), lung adenocarcinoma (OR = 1.45; 95% CI: 1.20–1.75; P < .01), and poorer 5-year overall survival (OS) rate (hazard radio = 2.33; 95%CI: 1.32–4.11; P < .01). The subgroup analyses and meta-regression analyses suggested that the “Publication year”, “Country”, “Sample size”, and “Cutoff value” might be the source of heterogeneity in TNM staging, differentiation degree, and lymph node metastasis. Both Begg test and Egger test verified that there were publication bias in 5-year OS rate. Sensitivity analysis supported the credibility of the results.Conclusion:The reduced NM23 expression is strongly associated with higher risk of NSCLC, higher TNM staging, poorer differentiation degree, positive lymph node metastasis, lung adenocarcinoma, and poorer 5-year OS rate in NSCLC patients, which indicated that NM23 could serve as a biomarker predicating the clinicopathological and prognostic significance of NSCLC.     

Association between plasminogen activator inhibitor-1 (PAI-1) 4G/5G polymorphism and risk of Alzheimer's disease,metabolic syndrome,and female infertility: A meta-analysis

Background:Plasminogen activator inhibitor-1 (PAI-1) is considered to be involved in the physiopathological mechanisms of Alzheimer''s disease (AD), metabolic syndrome (MetS), and female infertility. Previous studies investigating the association between PAI-14G/5G (rs1799889) gene polymorphism and the risk of AD, MetS, and female infertility have reported inconsistent results. The aim of the present study was to investigate possible associations.Methods:Eligible studies were retrieved through PubMed, Medline, EMBASE, CNKI, and WANFANG databases. The odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the associations. Subgroup analyses by ethnicity and mean age, sensitivity analyses, and publication bias were performed.Results:Five studies (four articles) for AD, six studies (six articles) for MetS, and four studies (four articles) for female infertility were included in this meta-analysis. Our results showed no significant associations between the PAI-14G/5G polymorphism and the risk of AD and female infertility in five genetic models. For the risk of MetS, the PAI-1 4G/5G (rs1799889) polymorphism may be associated with the risk of MetS (4G vs 5G, OR = 1.31, 95%CI = 1.04–1.64, P = .021), especially in Asians (4G/4G vs 4G/5G+5G/5G, OR = 1.38, 95%CI = 1.01–1.87, P = .041) and patients with mean age > 50 years old (4G/4G vs 4G/5G+5G/5G, OR = 1.36, 95%CI = 1.03–1.78, P = .029).Conclusion:The present meta-analysis suggested that the PAI-1 4G/5G polymorphism might be associated with the risk of MetS, but no evidence was detected for AD and female infertility.     

Prognostic and clinicopathological significance of miR-638 in cancer patients: A meta-analysis

Introduction:MiR-638 is believed to be involved in human cancers. However, the prognostic value of miR-638 in human carcinomas is controversial and inconclusive. Therefore, we conducted this meta-analysis to investigate the association between miR-638 expression and clinical outcomes in the patients with various cancers.Methods:We searched Pubmed, Embase, Wanfang, and the China National Knowledge Infrastructure (CNKI) up to September 1, 2020 to identify relevant studies. Hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were used to correlate expression of miR-638 with prognosis and clinicopathological features.Results:A total of 18 studies involving 1886 patients were included in the meta-analysis. The results revealed that low miR-638 expression was significantly correlated with poor overall survival (OS) (HR = 2.09, 95% CI: 1.46–2.98, P < .001), but not with disease-free survival (DFS) (HR = 1.71, 95% CI: 0.31–9.56, P = .540). Subgroup analysis found that low miR-638 expression was associated with worse OS in patients with digestive system cancer (HR = 2.47, 95% CI: 1.85–3.30, P < .001), the reported directly from articles group (HR = 2.12, 95% CI: 1.34–3.33, P < .001), survival curves group (HR = 2.02, 95% CI: 1.07–3.80, P = .029), in studies with sample size ≥100 (HR = 2.12, 95% CI: 1.34–3.35, P = .001), and in studies with sample size <100 (HR = 2.02, 95%CI: 1.09–3.75, P = .025). Moreover, cancer patients with low miR-638 expression were prone to tumor size (OR = 1.47, 95% CI: 1.03–2.09, P = .035), earlier lymph node metastasis (present vs absent, OR = 2.26, 95% CI: 1.63–3.14, P < .001), earlier distant metastasis (present vs absent, OR = 2.60, 95% CI: 1.45–4.67, P < .001), TNM stage (III-IV vs I-II, OR = 2.01, 95% CI: 1.35–2.99, P = .001), and portal vein invasion (present vs absent, OR = 4.39, 95% CI:2.23–8.64, P < .001), but not associated with age, gender, tumor differentiation, and vascular invasion.Conclusions:MiR-638 may serve as a promising indicator in the prediction of prognosis and clinicopathological features in patients with different kinds of cancers.     

A meta-analysis of the influence of body mass index on the clinicopathologic progression of papillary thyroid carcinoma

Background:Papillary thyroid carcinoma (PTC) incidence has been increasing worldwide. Obesity, that is, having a high body mass index, is associated with the incidence of several cancers including colon, breast, esophageal, and kidney cancer. However, the association between obesity and the clinical features of PTC is still unknown. This study aimed to determine the impact of obesity on the clinical features of PTC.Method:A database search was conducted for articles published up to 2020 on obesity and clinical features of PTC. Data were extracted from articles that met the meta-analysis inclusion criteria.Results:A total of 11 retrospective cohorts and 11,729 patients were included. Obesity was associated with the following variables in PTC patients: older age (difference in means = 1.95, 95% confidence interval [CI] 0.16–3.74, P = .03), male sex (odds ratio [OR] = 3.13, 95%CI 2.24–4.38, P < .00001), tumor size ≥1 cm (OR = 1.34, 95%CI 1.11–1.61, P < .002), multifocality (OR = 1.54, 95%CI 1.27–1.88, P < .0001), extrathyroidal extension (OR = 1.78, 95%CI 1.22–2.59, P = .003) and advanced tumor, node, metastasis stage (OR = 1.68, 95%CI 1.44–1.96, P < .00001). Preoperative serum thyroid-stimulating hormone level (difference in means  = 0.09, 95%CI 0.35–0.52, P = .70), Vascular invasion (OR = 0.84, 95%CI 0.56–1.26, P = .41), lymph node metastasis (OR = 1.07, 95%CI 0.87–1.32, P = .50), distant metastasis (OR = 1.14, 95%CI 0.64–2.04, P = .66), and recurrence (OR = 1.45, 95%CI 0.97–2.15, P = .07) were not associated with obesity.Conclusion:Obesity was associated with several poor clinicopathologic prognostic features: older age, male gender, tumor size ≥1 cm, extrathyroidal extension, multifocality, and advanced tumor/node/metastasis stage. However, thyroid-stimulating hormone level, vascular invasion, lymph node metastasis, distant metastasis, and recurrence were not associated with obesity in PTC.     

Cross-sectional study of diabetes kidney disease in the Eastern Cape,South Africa

Diabetes mellitus (DM) is an independent risk factor for the development of kidney disease. This study assesses the prevalence and determinants of asymptomatic kidney disease in individuals with DM attending health facilities in OR Tambo district, Eastern Cape, South Africa.In this cross-sectional analysis, medical data of 327 individuals receiving care for DM in primary health care centers in OR Tambo district, Eastern Cape between June and November 2013 were reviewed. Significant kidney disease was defined as estimated glomerular filtration rate less than 60 mL/min/1.73 m² in accordance with the guidelines of the Society of Endocrinology, Metabolism and Diabetes of South Africa (2017).One-quarter of the 327 participants (n = 80) had significant kidney disease. Female sex [odds ratio (OR) = 5.2; 95% confidence interval (95% CI) 1.2–23.5], never used alcohol (OR = 13.4; 95% CI 2.5–72.1), hypertension (OR = 16.2; 95% CI 2.0–130.0), triglyceride (TG)/high-density lipoprotein (HDL) ratio (OR = 1.2; 95% CI 1.0–1.5), current smoker (OR = 1127.9; 95% CI 162.9–7808.9), former smoker (OR = 13.3; 95% CI 4.1–41.4), and longer duration of diabetes (OR = 4.6; 95% CI 1.6–13.0) were the independent determinants of significant kidney disease among the participants. A significant dose--effect relationship exists between renal disease and smoking status (P < .0001), duration of DM (P < .001), glycemic status (P = .025), and body mass index (P = .003).There is a high rate of undiagnosed kidney disease in this setting, which was independently associated with female sex and presence of other cardiovascular risk factors. Strategic interventions targeting screening and monitoring of renal functions in individuals with DM are urgently needed in this region.     

Anlotinib,a novel TKI,as a third-line or further-line treatment in patients with advanced non-small cell lung cancer in China: A systemic review and meta-analysis of its efficacy and safety

Purpose:In this meta-analysis and systemic review, we focused on the effectiveness and safety of anlotinib in patients with advanced non-small cell lung cancer(NSCLC).Methods:The databases of PubMed, EMBASE, Cochrane Library, CNKI, Wanfang, and CBM were searched by 2 investigators up to April 2020. Titles and abstracts of all records were screened and eligible publications were retrieved in full. Review Manager (version 5.2, Cochrane Library) was used for data analysis. The outcomes of interest were disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse event (TRAE). Data was pooled for quantitative analysis and the effect size was reported as hazard ratio for survival outcomes and odds ratio (OR) for safety outcomes, both with a random-effects model.Results:A sum of 1480 patients were included in 11 trials ranging from 2018 to 2020. Substantial improvements of PFS, OS, and DCR were observed in patients treated with anlotinib alone or in combination with other conventional treatment. Accompanied TRAE included statistically significant higher risk for hypertension (OR = 11.05, 95% confidence interval [CI] = 7.85–15.55, P < .001), hepatic dysfunction (OR = 1.96, 95% CI = 1.29–2.68, P < .001), diarrhea (OR = 2.20, 95% CI = 1.17–4.16, P < .05), and hemoptysis (OR = 2.59, 95% CI = 1.71–3.93, P < .01).Conclusions:Our study suggested that anlotinib as maintenance therapy for advanced NSCLC patients is associated with prolonged PFS and OS as well as DCR improvement, but it was accompanied by increased risk of TRAE, such as hypertension, hepatic dysfunction, diarrhea and hemoptysis. Although much effort has been made to clinical trials of anlotinib, further studies are warranted to provide more convincing evidence.     

Prognostic significance of the expression of metastasis-associated in colon cancer-1 in gynecologic cancers and breast cancer: A protocol for systematic review and meta-analysis

Background:The prognostic role of the expression of metastasis-associated in colon cancer-1 (MACC1) in gynecologic cancers and breast cancer remains unclear. The aim of this systematic review and meta-analysis was to determine the prognostic significance of MACC1 expression in gynecologic cancers and breast cancer.Materials and methods:PubMed, Web of Science and Embase were comprehensively searched up to February 9, 2020. Studies focusing on the relationship between the expression of MACC1 and prognosis in gynecologic cancers and breast cancer were included into the analysis. Pooled hazard ratio (HR) or odd ratio with 95% confidence interval (CI) was used to estimate the prognostic value of the expression of MACC1.Results:A total of 1,811patients with gynecologic cancers or breast cancer were included into the analysis. Patients with high expression of MACC1 tended to suffer a shorter overall survival (HR = 2.76, 95%CI = 2.12–3.59, P < .01) and recurrence-free survival (HR = 2.37, 95%CI = 1.44–3.90, P < .01) compared to those with low expression of MACC1. High expression of MACC1 was significantly associated with worse tumor differentiation (P = .04), more advanced FIGO stage (P < .01) and earlier lymph node metastasis (P < .01) compared to low expression of MACC1.Conclusion:Compared to low expression of MACC1, high expression of MACC1 predicts a worse prognosis of gynecologic cancers and breast cancer. The expression of MACC1 can serve as a prognostic indicator of gynecologic cancers and breast cancer.     

Association between Alpha B-crystallin expression and prognosis in patients with solid tumors: A protocol for systematic review and meta-analysis

Background:Alpha B-crystallin (CRYAB), as a small heat shock protein, may play critical roles in the tumorigenesis and progression of several kinds of human cancers. However, the prognostic value of CRYAB in solid malignancies remains controversial. The aim of the present study was to investigate the association between CRYAB expression and clinicopathology and prognosis of solid tumor patients.Methods:PubMed, Web of Science, EMBASE, Chinese National Knowledge Infrastructure, and WanFang databases were systematically searched to retrieve studies that investigated the prognostic value of CRYAB expression in various solid tumors. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to determine the strength of association between CRYAB expression and survival in patients with solid tumors. Odds ratios (ORs) with 95% CIs were pooled to assess the correlation between CRYAB expression and clinicopathological characteristics of patients with solid tumors.Results:A total of 17 studies, including 18 cohorts with 6000 patients, were included in this meta-analysis. Our results showed that increased CRYAB expression could predict poor overall survival (HR = 1.81, 95% CI: 1.50–2.19, P < .001), disease-free survival (HR = 1.47, 95% CI: 1.16–1.86, P = .001), and disease-specific survival (HR = 1.40, 95% CI: 1.19–1.63, P < .001) in patients with cancer. Furthermore, the high expression level of CRYAB was associated with certain phenotypes of tumor aggressiveness, such as lymph node metastasis (OR = 2.46, 95% CI: 1.48–4.11, P = .001), distant metastasis (OR = 3.34, 95% CI: 1.96–5.70, P < .001), advanced clinical stage (OR = 2.24, 95% CI: 1.24–4.08, P = .008), low OS rate (OR = 4.81, 95% CI: 2.82–8.19, P < .001), and high recurrence rate (OR = 1.38, 95% CI: 1.11–1.72, P = .004).Conclusions:CRYAB may serve as a valuable prognostic biomarker and therapeutic target in human solid tumors.     

Correlation between single nucleotide polymorphisms in the 3 primer untranslated region of PTX3 and the risk of essential hypertension: A case–control study

The aim of this study was to investigate the correlation between single-nucleotide polymorphisms (SNPs) in the 3 primer of untranslated region (3’UTR) of the Pentraxin 3 (PTX3) gene and the risk of essential hypertension (EHT).PTX3 genotypes, rs2614, rs111451363, and rs73158510 locus, were found in 260 patients with EHT and 260 healthy controls. Quantitative real-time polymerase chain reaction was used to detect plasma hsa-miR-4766-5p levels. Enzyme-linked immunosorbent assay was used to detect plasma PTX3 levels. The dual-luciferase reporter assay was used to identify the binding site of hsa-miR-4766-5p to the PTX3.PTX3 rs2614 locus T allele was a high risk factor for EHT (odds ratio [OR] = 2.76, 95% confidence interval [CI]: 1.86–4.09, P < .01). Sex and diabetes history affected the correlation between PTX3 gene rs2614 locus SNP and EHT risk. The CCG haplotype was a protective factor for EHT (OR = 0.40, 95% CI: 0.28–0.57, P < .01), whereas the TCG haplotype was a risk factor for EHT (OR = 2.35, 95% CI: 1.51–3.66, P < .01). The plasma PTX3 level of patients with EHT was significantly higher than that of the control group, and the difference was statistically significant (P < .01). The area under the curve for EHT diagnosis in plasma PTX3 levels was 0.62 (95% CI: 0.57–0.66, P < .01). The plasma hsa-miR-4766-5p level in patients with EHT was significantly lower than that in the control group (P < .01). The area under the curve for the diagnosis of EHT according to the plasma hsa-miR-4766-5p level was 0.88 (95% CI: 0.85–0.91, P < .01). Plasma PTX3 levels were significantly negatively correlated with hsa-miR-4766-5p levels in patients with EHT and the control group (r = −0.87, −0.85, P < .01, P < .01). The PTX3 gene rs2614 locus C allele was the target gene of hsa-miR-4766-5p.The PTX3 rs2614 locus SNP is significantly associated with EHT risk.     

Association between CASC16 rs4784227 polymorphism and breast cancer susceptibility: A meta-analysis

Objective:To explore whether rs4784227 polymorphism of CASC16 is correlated with risk of breast cancer.Methods:Relevant studies up to December 24, 2020 were searched in PubMed, Embase, Web of Science, CNKI, VIP, and WANFANG databases. Data were analyzed by using Stata 12.0. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated, and country-based subgroup analyses were conducted. Sensitivity analysis was conducted to assess the stability of the results. Publication bias was assessed by using the Egger regression asymmetry test and visualization of funnel plots.Results:Seven case-control studies enrolling 4055 breast cancer cases and 4229 controls were included. rs4784227 was found significantly associated with increased risk of breast cancer in a dominant (OR = 1.301, 95% CI = 1.190–1.423, P < .001), a recessive (OR = 1.431, 95% CI = 1.216–1.685, P < .001), and an allele model (OR = 1.257, 95% CI = 1.172–1.348, P < .001), while an over-dominant model showed that rs4784227 was correlated with decreased breast cancer risk (OR = 0.852, 95% CI = 0.778–0.933, P = .001).Conclusion:The rs4784227 polymorphism of CASC16 gene is correlated with breast cancer susceptibility.
