For each 25 cm2 higher visceral fat at baseline, the odds of fibrosis progression increased by 37% (OR 1.37, 95% CI 1.03, 2.07). There was no difference in baseline NAS score between fibrosis progressors and non-progressors, though NAS score rose over time in the progressor group (1.1±0.8 vs. -0.5±0.6, P less then 0.0001). CONCLUSIONS In this longitudinal study of HIV-associated NAFLD, high rates of hepatic fibrosis and progression were observed. Visceral adiposity was identified as a novel clinical predictor of worsening fibrosis. In contrast, baseline histologic characteristics were not found to relate to fibrosis changes over time. Further studies are needed to identify additional biomarkers of accelerated disease. © The Author(s) 2020. Published by Oxford University Press for the Infectious Diseases Society of America.

It is also associated with injection drug use, a behavior that has increased in recent years along with the U.S. opioid crisis. METHODS We conducted a retrospective cohort analysis of commercial and Medicaid health insurance databases to estimate incident cases of IE in the United States in 2017, stratified by HIV, HCV infection and opioid use disorder (OUD). We also estimated annual percentage changes (EAPCs) in IE from 2007-2017 among persons with commercial insurance. RESULTS The weighted incidence rate of IE was 13.8 cases per 100,000 persons among persons with commercial insurance, and 78.7 among those with Medicaid. The incidence rate of IE among commercially insured persons increased slightly from 2007-2017 (EAPC 1.0%). It decreased among commercially insured persons with HIV from 148.0 in 2007 to 112.1 in 2017 (EAPC -4.3%) and increased among those with HCV infection from 172.4 to 238.6 in 2017 (EAPC 3.2%). Among persons aged 18-29 years with HCV infection, IE increased from 337.6 in 2007 to 1028.7 in 2017 (EAPC 15.3%), and among those with OUD it increased from 156.4 in 2007 to 642.9 in 2017 (EAPC 13.8%). CONCLUSIONS The incidence rate of IE increased markedly among young persons with HCV infection or OUD. This increase appears to parallel the ongoing national opioid crisis. Harm reduction with syringe services programs, medications for opioid use disorder, and safe injection practices can prevent HIV, HCV, and IE.

METHODS The present study included data of 152 patients admitted to the Department of Radiochemotherapy, Tangshan People’s Hospital, who developed ARP (91 patients) or infectious pneumonia (IP; 61 patients) after radiotherapy. The radiophysical parameters, imaging characteristics, serological indicators, and other data were collected as independent variables, and ARP was considered as a dependent variable. Logistics univariate analysis and Spearman correlation analysis were used for selecting independent variables. Logistics multivariate analysis was used to fit the variables into the regression model to predict ARP. RESULTS The univariate analysis showed that the positional relation between lesions and V20 area (PRLV), procalcitonin (PCT), C-reactive protein (CRP), mean lung dose (MLD), and lung volume receiving ≥20 Gy (V20) correlated with ARP while the planning target volume (PTV) dose marginally correlated with ARP. The multivariate analysis showed that the PRLV, PCT, white blood cell (WBC), and MLD were independent diagnostic factors. The nomogram was drawn on the basis of the logistics regression model. check details The area under the curve (AUC) of the model was 0.849, which was significantly better than that of a single indicator and the sensitivity and specificity of the model were high (82.4 and 82.0%, respectively). These results predicted by the model were highly consistent with the actual diagnostic results. The decision curve analysis (DCA) demonstrated a satisfactory positive net benefit of the model. CONCLUSION The diagnosis model constructed in the present study is of certain value for the differential diagnosis of ARP and IP. © 2020 The Author(s).Expression of proinflammatory cytokines, such as interleukin (IL)-6 (IL-6) and metalloproteases, are elevated in patients with rotator cuff tear (RCT). In order to investigate the role of IL-6 gene polymorphisms on RCT risk, we genotyped two SNPs on IL-6 gene (rs1800795 and rs1800797) in 138 RCT patients and 137 healthy controls using polymerase chain reaction (PCR) and Sanger sequencing. The IL-6 expression in shoulder joint synovial fluid was determined by using enzyme-linked immunosorbent assay (ELISA) method. The constant score and visual analog scale (VAS) were used to evaluate the clinical outcome of two s (surgicsal vs. conservative) for RCT patients. For rs1800795, individuals with the GG genotype or G allele had significantly higher risk of RCT. Elevated risk of tear size was associated with the GG genotype of the rs1800795 polymorphism. The IL-6 rs1800797 polymorphism was also associated with an increased risk of RCT, especially among female, drinkers, and individuals with B(MI) less then 25 kg/m2. The elevated levels of IL-6 gene were observed among the mutant genotype of rs1800795/rs1800797 polymorphism. Surgical group is significantly better than conservative treatment from the perspective of constant score and VAS. Furthermore, CG genotype of rs1800795 polymorphism increased the constant score at 6 months in comparison with CC genotype. In conclusion, our study supports a role of IL-6 rs1800795/rs1800797 polymorphisms on increased RCT risk. The RCT patients with CG genotype of rs1800795 polymorphism have more obvious surgical treatment effects by influencing the IL-6 expression. © 2020 The Author(s).
