Hearing impairment prevalence and risk factors among adults in rural China: a population-based cross-sectional study.
Objective: Over the past few decades, the prevalence of hearing impairment (HI) has rapidly increased, making HI one of the most common causes of disability, globally. The burden of HI is particularly heavy in low socioeconomic status populations. Despite extensive research into the range of HI prevalence in low socioeconomic status populations, worldwide, population-based studies have been rare. ⋯ Compared with the 45-54-year-old group, the risk of HI in individuals in the 55-64-year-old, 65-74-year-old, and ≥75-year-old groups were 25.8%, 109.9%, and 373.7% higher, respectively. Moreover, increased with each 1-mmHg SBP, the risk of HI increase 0.7% (95%CI: 1.001-1.013; P = 0.017); while increased with each 1-mmHg DBP, the risk of HI decrease 1.7% (95%CI: 0.973-0.993; P = 0.001)Conclusions: The burden of HI in rural northern China is heavy, especially among elderly men and people with elevated systolic blood pressure (SBP). Addressing HI prevention is critical for reducing the HI burden and improving quality of life.

Similar clinical outcome of AMA immunoblot-M2-negative compared to immunoblot-positive subjects over six years of follow-up.
Background: The detection of anti-mitochondrial antibodies (AMA) is considered a hallmark in diagnosing primary biliary cholangitis (PBC). The most important AMA-subtype is AMA-M2 directed against the E2-subunit of pyruvate dehydrogenase. It is common clinical interpretation that lack of M2 due to immunoblotting (IB) indicates absence of specific auto-reactivity. ⋯ According to the clinical course by the time of FU, subjects were allocated to one of four groups: a) 34 patients had known PBC with n = 16 having an adequate and 18 an inadequate treatment response, b) 1 de novo PBC was detected, c) 13 were AMA-positive without biochemical evidence of PBC and d) 9 subjects were tested AMA-negative at FU. These numbers were comparable to M2-positive subjects with similar long-term clinical outcome. Conclusion: Our data suggest that the clinical value of confirmatory M2 immunoblotting in the diagnostic routine of PBC is overestimated as the clinical course appears not to be related to the test result.

Background and aim: The diagnosis of Crohn's disease (CD) is challenging. Ongoing search for biomarkers to facilitate the diagnosis is a worthwhile endeavor. The aim of this study was to explore the role of serological markers in the diagnosis of CD at an inflammatory bowel disease (IBD) referral center. ⋯ However, a decreased proportion of AYMA+ CD patients was found in those who received surgery compared with their non-surgical counterparts (p = 0.0488). Conclusions: ASCA was found to be the most accurate serological marker for the differential diagnosis of CD. Combinations of ASCA, AYMA, AYCA, and FI2Y improved diagnostic accuracy of CD.

Usefulness of Atherogenic index of plasma for estimating Reduced eGFR risk: Insights from the National Health and Nutrition Examination Survey 2009-2016.
Previous studies have identified Atherogenic index of plasma (AIP) as a simple measure of atherosclerosis. Because atherosclerosis plays a role in the development of renal damage, our study aims to evaluate the effect of AIP on the risk of reduced eGFR and assess its usefulness to refine the risk stratification of reduced estimated glomerular filtration rate (eGFR). ⋯ The present work suggested a linear association between AIP and reduced eGFR. Furthermore, the results showed that the association was stronger in black race and people aged less than 50 years old. Most importantly, our work implicated the usefulness of AIP to refine the risk stratification of reduced eGFR.

The relevance of practical laboratory markers in predicting gastrointestinal and renal involvement in children with Henoch-Schönlein Purpura.
Henoch-Schönlein Purpura (HSP) is the most common self-limiting vasculitis of childhood. Both serious gastrointestinal and renal complications may be observed during the disease course. The aim of this study was to evaluate the role of hematological markers in predicting the likely complications of the disease. ⋯ This study had shown that platelet counts, neutrophil counts, NLR, and PLR were increasing and lymphocyte counts, MPV, and MPR were decreasing when the patients had GIS involvement. However, these parameters were not relevant in distinguishing severe and mild GIS involvement. When patients had renal involvement NLR was the unique elevated parameter.
