Selenium (Se) is an essential element to human health that can be obtained in nature through several sources. In the human body, it is incorporated into selenocysteine, an amino acid used to synthesize several selenoproteins, which have an active center usually dependent on the presence of Se. Although Se shows several beneficial properties in human health, it has also a narrow therapeutic window, and therefore the excessive intake of inorganic and organic Se-based compounds often leads to toxicity. Nanoparticles based on Se (SeNPs) are less toxic than inorganic and organic Se. find protocol They are both biocompatible and capable of effectively delivering combinations of payloads to specific cells following their functionalization with active targeting ligands. Herein, the main origin of Se intake, its role on the human body, and its primary biomedical applications are revised. Particular focus will be given to the main therapeutic targets that are explored for SeNPs in cancer therapies, discussing the different functionalization methodologies used to improve SeNPs stability, while enabling the extensive delivery of drug-loaded SeNP to tumor sites, thus avoiding off-target effects.
A low skeletal muscle mass (SMM) has been associated with increased toxicity and shorter survival in cancer patients treated with capecitabine, an oral prodrug of 5-fluorouracil (5-FU). Capecitabine and its metabolites are highly water-soluble and, therefore, more likely to distribute to lean tissues. The pharmacokinetics (PK) in patients with a low SMM could be changed, for example, by reaching higher maximum plasma concentrations. In this study, we aimed to examine whether the association between a low SMM and increased toxicity and shorter survival could be explained by altered PK of capecitabine and its metabolites.

Previously, a population PK model of capecitabine and metabolites in patients with solid tumors was developed. In our analysis, we included patients from this previous analysis for which evaluable abdominal computed tomography (CT)-scans were available. SMM was measured on CT-scans, by single slice evaluation at the third lumbar vertebra, using the Slice-o-Matic software. The previously delite 5-FU were observed in patients with a low SMM. Therefore, the previously identified increased toxicity and shorter survival in patients with a low SMM, could not be explained by changes in pharmacokinetic characteristics of capecitabine and metabolites.
African-American (AA) and Hispanic/Latina (HL) females have higher obesity prevalence than do non-Hispanic Whites (NHW); this may be due to AA and HL consuming more energy-dense foods in response to stressors.

This study examined racial/ethnic differences in dietary intake under controlled conditions (relaxation and stress) in a diverse sample of adolescent females.

Participants included 120 adolescent females (30% AA, 37% HL and 33% NHW) who participated in a laboratory food intake study. Using a randomized cross-over design, ad libitum food consumption was measured following control/relaxation and social-evaluative stress conditions. Food intake was indexed as consumed calories, added sugars and solid fats.

The effect of laboratory conditions on food intake varied by race/ethnicity, such that AA consumed more energy following relaxation than following stress. For NHW and HL, food intake did not differ between conditions.

To the best of our knowledge, these findings are the first to directly observe racial/ethnic differences in food intake in response to acute stress, which may contribute to obesity-related health disparities.

Patients with heart failure (HF) suffer from reduced quality-of-life (QoL). We aimed to compare QoL, depression, and anxiety scores among outpatients with preserved (HFpEF) and reduced (HFrEF) ejection fraction and non-HF controls and its relationship to coordination capacity.

Fifty-five participants were recruited prospectively at the University Hospital Jena, Germany (17 HFpEF, 18 HFrEF, and 20 non-HF controls). All participants underwent echocardiography, cardiopulmonary exercise testing (CPET), 10m walking test (10-MWT), isokinetic muscle function and coordination tests, and QoL assessments using the short form of health survey (SF-36), and hospital anxiety and depression scale (HADS). Furthermore, inflammatory biomarkers such as growth differentiation factor-15 (GDF-15) were assessed. Patients with HFpEF showed compared with HFrEF and non-HF controls reduced QoL [mental component score (MCS) 43.6±7.1 vs. 50.2±10.0 vs. 50.5±5.0, P=0.03), vitality (VT) 47.5±8.4 vs. 53.6±8.6 vs. 57.1±5.2, P=0.004), and controls. Depression is associated with reduced QoL and is an independent predictor for reduced coordination capacity.
Patients with inflammatory arthritis (IA) have a high risk of sleep disturbances and disorders. The objective was to evaluate the evidence of non-pharmacological interventions targeting sleep disturbances or disorders in patients with IA.

A systematic search was undertaken from inception to September 8
, 2020. We included randomized trials concerning non-pharmacological interventions applied in adults with IA and concomitant sleep disturbances or disorders. Primary outcome was the sleep domain while secondary outcomes were core outcome domains for IA trials and harms. The Cochrane Risk of Bias tool was applied, and the overall quality of the evidence was assessed using GRADE. Effect sizes for continuous outcomes were based on the standardized mean difference, combined using random-effects meta-analysis.

Six trials (308 patients) were included in the quantitative synthesis; three of these reported improvement in sleep in favor of the non-pharmacological intervention(s). The meta-analysis of the sleep domains indicated a large clinical effect of -0.80 (95% CI, -1.33 to -0.28) in favor of non-pharmacological interventions targeting sleep disturbances or disorders. The estimate was rated down twice for risk of bias, and unexplained inconsistency; this was assessed as corresponding to low quality evidence. None of the secondary core outcomes used in contemporary IA trials indicated clinical benefit in favor of non-pharmacological interventions targeting sleep.

Non-pharmacological interventions targeting sleep disturbances/disorders in patients with IA indicated a promising effect on sleep outcomes, but not yet with convincing evidence.
