Elderly individuals who ambulate have a 30.08% chance of not being considered sarcopenic. In addition, biochemical and anthropometric indicators demonstrated a relationship of sarcopenia with malnutrition.

Sarcopenia is associated with a loss of body mass, not only selective muscle mass, and greater physical inability to ambulate.

Damage to the vascular endothelium is strongly implicated in the pathogenesis of idiopathic inflammatory myopathies (IIM). Normally, high-density lipoprotein (HDL) protectsthe vascular endothelium from damage from oxidized phospholipids, which accumulate under conditions of oxidative stress. The current work evaluated the antioxidant function of HDL in IIM patients.

HDL's antioxidant function was measured in IIM patients using a cell-free assay, which assesses the ability of isolated patient HDL to inhibit oxidation of low-density lipoproteins and is reported as the HDL inflammatory index (HII). Cholesterol profiles were measured for all patients, and subgroup analysis included assessment of oxidized fatty acids in HDL and plasma MPO activity. A subgroup of IIM patients was compared with healthy controls.

The antioxidant function of HDL was significantly worse in patients with IIM (n = 95) compared with healthy controls (n = 41) [mean (S.d.) HII 1.12 (0.61) vs 0.82 (0.13), P < 0.0001]. Higher HII associated with higher plasma MPO activity [mean (S.d.) 13.2 (9.1) vs 9.1 (4.6), P = 0.0006] and higher oxidized fatty acids in HDL. Higher 5-hydroxyeicosatetraenoic acid in HDL correlated with worse diffusion capacity in patients with interstitial lung disease (r = -0.58, P = 0.02), and HDL's antioxidant function was most impaired in patients with autoantibodies against melanoma differentiation-associatedprotein 5 (MDA5) or anti-synthetase antibodies. In multivariate analysis including 182 IIM patients, higher HII was associated with higher disease activity and DM diagnosis.

The antioxidant function of HDL is abnormal in IIM patients and may warrant further investigation for its role in propagating microvascular inflammation and damage in this patient population.

Analysis of circulating tumor DNA (ctDNA) allows the noninvasive molecular profiling of tumor, and such analysis has gained popularity for the detection of mutations with therapeutic implications. A value-based assessment would be useful for an objective evaluation of the benefits of ctDNA testing.

The value proposition approach was used to evaluate the benefits of implementing ctDNA testing to inform treatment decisions of targeted therapy. The ctDNA testing was shown to complement tumor biopsy testing for the detection of mutations that are predictive of treatment response. It might be particularly useful for tracking resistance mechanisms among patients who experience disease progression despite treatment.

Patients, clinicians, and laboratory medicine specialists would benefit from the implementation of appropriate ctDNA testing in routine clinical care.

There are scarce data about SARS-CoV-2 infection in patients with inflammatory bowel disease (IBD). Our aim was to analyze the incidence, clinical presentation, and severity of SARS-CoV-2 infection in patients with IBD.

This is a cross-sectional, observational study. We contacted all the patients being treated at our IBD unit to identify those patients with suspected or confirmed SARS-CoV-2 infection, following the World Health Organization case definition. Data were obtained by patient electronical medical records and by phone interview.

Eighty-two of 805 patients with IBD (10.2%; 95% confidence interval [CI], 8.3-12.5) were diagnosed as having confirmed (28 patients, 3.5%; 95% CI, 2.4-5.0) or suspected (54 patients, 6.7%) infection. Patient age was 46 ± 14 years, 44 patients were female (53.7%), 17.3% were smokers, 51.2% had Crohn disease (CD), and 39.0% had comorbidities. Digestive symptoms were reported in 41 patients (50.0%), with diarrhea as the most common (42.7%). One patient (1.2%) was diagnose COVID-19, and SARS-CoV-2 infections do not appear to be related to IBD flare-ups.COVID-19 is caused by the SARS-CoV-2 virus, which has infected more than 4 million people with 278 892 deaths worldwide as of 11 May 2020. This disease, which can manifest as a severe respiratory infection, has been declared as a public health emergency of international concern and is being treated with a variety of antivirals, antibiotics and antifungals. selleck chemicals llc This article highlights the administration of antimicrobials in COVID-19 patients worldwide, during the 2019-20 pandemic. It is imperative to be aware of the unreported amounts of antibiotics that have been administered worldwide in just a few months and a marked increase in antimicrobial resistance should therefore be expected. Due to the lack of data about antimicrobial use during this pandemic, the global impact on the emergence of new antimicrobial resistance is as yet unknown. This issue must be at the forefront of public health policymaking and planning in order that we are prepared for the potentially severe consequences for human and animal health and the environment.
Protein-energy wasting, muscle mass (MM) loss and sarcopenia are highly prevalent and associated with poor outcome in haemodialysis (HD) patients. Monitoring of MM and/or muscle metabolism in HD patients is of paramount importance for timely detection of muscle loss and to intervene adequately. In this study we assessed the reliability and reproducibility of a simplified creatinine index (SCI) as a surrogate marker of MM and explored its predictive value on outcome.

We included all in-centre HD patients from 16 European countries with at least one SCI. The baseline period was defined as 30 days before and after the first multifrequency bioimpedance spectroscopy measurement; the subsequent 7 years constituted the follow-up. SCI was calculated by the Canaud equation. Multivariate Cox proportional hazards models were applied to assess the association of SCI with all-cause mortality. Using backward analysis, we explored the trends of SCI before death. Bland-Altman analysis was performed to analyse the agreement between estimated and measured MM.
