Introduction: Dysphagia is a prevalent condition (20%), and occurs more frequently in women and in older people. It negatively impacts innumerous aspects of patient's personal and professional lives. Patient-reported outcomes allow patients to directly quantify their experience regarding dysphagia and evaluate its true impact on quality of life.

To keep faith with homoskedasticity or to go back to heteroskedasticity? The case of FATANG stocks.

Did the pattern of US stock market volatility change due to COVID-19 or have the US stock markets been less volatile despite the pandemic shock? And as for tech stocks, are they even less volatile than the market overall? In this paper, we provide evidence in favor of a "quietness" in the stock markets, interrupted by COVID-19, by analyzing dispersion, skewness and kurtosis characteristics of the empirical distribution of nine returns series that include individual FATANG stocks (FAANG: Facebook, Amazon, Apple, Netflix and Google; plus Tesla) and US indices (S&P 500, DJIA and NASDAQ). In comparison with the years before, the daily average return after COVID-19 was 6.48, 2.

Ankle--brachial index, vascular calcifications and mortality in dialysis patients.

Background: The ankle-brachial index (ABI) is a noninvasive method to evaluate peripheral artery disease (PAD). ABI <0.9 diagnoses PAD; ABI >1.

Low bone volume--a risk factor for coronary calcifications in hemodialysis patients.

Background And Objectives: There is increasing evidence that altered bone metabolism is associated with cardiovascular calcifications in patients with stage 5 chronic kidney disease on hemodialysis (HD). This study was conducted to evaluate the association between bone volume, turnover, and coronary calcifications in HD patients.

Design, Setting, Participants, & Measurements: In a cross-sectional study, bone biopsies and multislice computed tomography were performed in 38 HD patients.

Bone mineral density, vascular calcifications, and arterial stiffness in peritoneal dialysis patients.

The objective of this study was to evaluate the correlation of bone mineral density (BMD), evaluated by DXA, with vascular calcifications, arterial stiffness, and vascular disease in patients on peritoneal dialysis. Vascular calcifications were evaluated by vascular calcification score on plain x ray, and arterial stiffness was measured by pulse wave velocity using the Complior device (Artech Medical, Pantin, France). Adjusting for multiple factors, lower BMD at the femoral neck, but not at the lumbar spine, was associated with higher pulse wave velocity (p = 0.

A plain X-ray vascular calcification score is associated with arterial stiffness and mortality in dialysis patients.

Background: Vascular calcifications are highly prevalent in dialysis patients and are associated with arterial stiffness and mortality. The use of simple and inexpensive methods to evaluate arterial stiffness and vascular calcifications is desired. The objective of this study was to evaluate the relationship of a simple vascular calcification score (SVCS) with pulse wave velocity (PWV) and pulse pressure (PP) and to evaluate their association with all-cause mortality.
