Background Vitamin D supplementation lowers exacerbation frequency in severe vitamin D-deficient patients with COPD. Data regarding the effect of vitamin D on elastin degradation are lacking. Based on the vitamin's anti-inflammatory properties, we hypothesised that vitamin D supplementation reduces elastin degradation, particularly in vitamin D-deficient COPD patients. We assessed the effect of vitamin D status and supplementation on elastin degradation by measuring plasma desmosine, a biomarker of elastin degradation. Methods Desmosine was measured every 4 months in plasma of 142 vitamin D-na

The present study aimed to determine if the use of NTTP‐contaminated sitagliptin, in comparison with other dipeptidyl peptidase‐4 (DPP‐4) inhibitors, is associated with an increased cancer risk.

Abstract Background Limited evidence exists on the role of glucose-lowering drugs in patients with COVID-19. Our main objective was to examine the association between in-hospital death and each routine at-home glucose-lowering drug both individually and in combination with metformin in patients with type 2 diabetes mellitus admitted for COVID-19. We also evaluated their association with the composite outcome of the need for ICU admission, invasive and non-invasive mechanical ventilation, or in-hospital death as well as on the development of in-hospital complications and a long-time hospital st

Objective: To detect common chromosomal aneuploidy variations in embryos from couples undergoing assisted reproductive technology and preimplantation genetic screening and their possible associations with embryo quality. Methods: In this study, 359 embryos from 62 couples were screened for chromosomes 13, 21, 18, X, and Y by fluorescence insitu hybridization. For biopsy of blastomere, a laser was used to remove a significantly smaller portion of the zona pellucida. One blastomere was gently biopsied by an aspiration pipette through the hole.

Whether the access-site of preprocedural coronary angiography (CAG) affects TAVR-related complications is not known. The aim of this study was to evaluate the impact of transradial (TRA) versus transfemoral access (TFA) for preprocedural CAG on outcomes in patients undergoing subsequent TAVR. Methods: The study cohort included 1002 patients undergoing transfemoral TAVR, of whom 39.4% (395/1002) had undergone radial and 60.6% (607/1002) femoral access for pre-TAVR CAG. The

Abstract Background Central nervous system depressant medications (CNSDs) such as opioid analgesics and sedative-hypnotics are commonly prescribed to older patients for the treatment of chronic pain, anxiety and insomnia. Yet, while many studies reported potential harms, it remains unknown whether persistent use of these medications is beneficial for older patients’ self-reported health-related quality of life (HRQoL). The present study clarified this knowledge gap through comparing HRQoL of hospitalized older patients with versus without using CNSD drugs for ≥4 weeks. Moreover, we explored th
