Abstract Uric acid (UA) is associated with non-alcoholic fatty liver disease (NAFLD). However, it is unclear whether UA plays a predictive role in NAFLD prognosis. This study aimed to explore the relationship between UA levels and mortality in NAFLD patients without severe renal disease. Data were obtained from the Third National Health and Nutrition Examination Survey (NHANES). Time-dependent Cox regression was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for mortality. Overall, 2493 individuals with NAFLD and estimated glomerular filtration rate (eGFR) > 60 mL/min/1.73 m2 were included in this study. The median follow-up period was 26.58 years. Patients were divided into high and low-UA groups according to UA levels. Time-independent Cox regression showed that UA level was not an independent risk factor for mortality in NAFLD patients without decreased eGFR (P > 0.05). After matching for age and sex using the propensity score matching method, UA remained not independently associated with death in NAFLD patients (P > 0.05). Similar results were found for cardiovascular-related and cancer-related deaths. Although UA is closely related to NAFLD, UA levels are not independently associated with the long-term survival of patients with NAFLD without decreased eGFR.

Abstract Background and objectives Dietary control and increased physical activity (PA) are recommended for patients with metabolic (dysfunction-) associated fatty liver disease (MAFLD). However, not all patients can sustain both exercise and a healthy diet. This study explored the interaction between dietary quality, PA levels, and mortality in MAFLD patients. Methods The Third National Health and Nutrition Examination Survey and linked mortality data were used in this study. Diet quality was assessed with the Healthy Eating Index (HEI). PA level was calculated by multiply self-reported exercise frequency and its Metabolic Equivalent A high-quality diet was associated. A Cox proportional hazard model was used to explore risk factors for mortality in MAFLD patients. Results In total, 3709 participants with MAFLD were included in the final analysis. The median follow-up time was 26.2 (interquartile range 19.3–28.1) years and 1549 (41.8%) deaths were recorded over follow-up. Cox multivariate regression was used to adjust for potential confounders of mortality. The results showed both HEI score and PA level were inversely correlated with all-cause mortality (P

Abstract Syphilis is a global public health concern. This study aimed to assess the global and regional burden of syphilis from 1990 to 2019. Disease burden was evaluated using disability-adjusted life-years (DALYs) and prevalence. Data were extracted from the 2019 global burden of disease Study, an open database available for download. Age-standardized rates (ASR) and estimated annual percentage changes (EAPC) were calculated to evaluate the syphilis burden over time. In 2019, the total number of prevalent cases of syphilis was 49.71 million worldwide. The ASR of prevalence was stable from 1990 to 2019 with an EAPC of 0.00 (95% CI − 0.10–0.11). The number of DALYs caused by syphilis was 7.36 million in 2019, reflecting a reduction of 16.38% compared with that in 1990 (8.80 million). The ASR of DALYs exhibited a decreasing trend from 1990 to 2019 (EAPC = − 1.01; 95% CI − 1.19 to − 0.84), with the highest rates observed in the younger age group (

Abstract High body mass index (BMI) has been associated with better survival in patients with end‐stage kidney disease. Individuals with fatty liver disease (FLD) have a higher risk of chronic kidney disease. It remains unclear whether the survival benefit of high BMI in patients with chronic kidney disease is present when there is concomitant FLD. This study used the data set from the Third American National Health and Nutrition Examination Survey and the corresponding survival data. The Cox proportional hazards model was used to evaluate the effect of BMI on mortality. A total of 12,445 participants were included. The prevalence of FLD was 39.8%. The median follow‐up time (with interquartile range) was 22.8 (20.8–24.8) years. During this period, 3749 (30.1%, 14.4 of 1000 person‐year) deaths were observed. Among these, 1169 (31.2%) died within the first 10 years. The Cox regression analysis showed that the BMI level was not associated with 25‐year mortality in patients with decreased glomerular filtration rate (GFR

High-sensitive C-reactive protein (hs-CRP) is one of the diagnostic components for metabolic (-dysfunction) associated fatty liver disease (MAFLD). This study aimed to explore the relationship between hs-CRP level and 25-year mortality in patients with MAFLD. The study data were from the Third National Health and Nutrition Examination Survey 1988–1994. All participants were followed up until December 2015 and the outcome of each participant was ascertained from National Death Index records. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence interval (CI) of all-cause mortality, cardiovascular-related mortality, and malignancy-related mortality. A total of 4,145 participants with MAFLD were included in final analysis. The median follow-up period was 22.3 years (interquartile range 16.9–24.2). There were 1,610 (38.8%) all-cause deaths. The leading cause of death was malignant neoplasms (365/1,610, 22.7%), followed by cardiovascular diseases (342/1,610, 21.2%). Of the 4,145 patients with MAFLD, 1,293 (31.2%) had an hs-CRP level greater than 0.5 mg/dl. Those with hs-CRP > 0.5 mg/dl were older, more likely to be female and had greater derangements of metabolic profiles than those with lower hs-CRP. The results of Cox regression analysis showed that hs-CRP ≥ 0.5 mg/dl was an independent risk factor for all-cause mortality (HR = 1.394, 95% CI 1.253–1.551), cardiovascular mortality (HR = 1.497, 95% CI 1.190–1.885) and malignant neoplasms related mortality (HR = 1.290, 95% CI 1.030–1.615) after adjusting for risk factors. This study confirms that hs-CRP is an independent predictive factor of poor prognosis in patients with MAFLD.

Objectives: Coronavirus Disease 2019 (COVID-19) is a new respiratory and systemic disease which needs quick identification of potential critical patients. This meta-analysis aimed to explore the relationship between lymphocyte count and the severity of COVID-19. Methods: A comprehensive systematic literature search was carried out to find studies published from December 2019 to 22 March 2020 from five databases. The language of literatures included English and Chinese. Mean difference (MD) of lymphocyte count in COVID-19 patients with or without severe disease and odds ratio (OR) of lymphopenia for severe form of COVID-19 was evaluated with this meta-analysis. Results: Overall 13 case-series with a total of 2282 cases were included in the study. The pooled analysis showed that lymphocyte count was significantly lower in severe COVID-19 patients (MD -0.31 × 109/L; 95%CI: -0.42 to -0.19 × 109/L). The presence of lymphopenia was associated with nearly threefold increased risk of severe COVID-19 (Random effects model, OR = 2.99, 95% CI: 1.31-6.82). Conclusions: Lymphopenia is a prominent part of severe COVID-19 and a lymphocyte count of less than 1.5 × 109/L may be useful in predicting the severity clinical outcomes.

Vitamin D deficiency is associated with high susceptibility to infections. The present study aimed at exploring the relationship between vitamin D levels and Toxoplasma gondii ( T. gondii ) infection, on the basis of a nationally representative database. The study data came from the National Health and Nutrition Examination Surveys (NHANES) 2001–2004. Participants underwent both Toxoplasma IgG antibody testing and serum vitamin D testing. Vitamin D deficiency was defined by a serum 25-hydroxyvitamin D level
