Vitamin D levels and mortality with SARS-COV-2 infection: a retrospective two-centre cohort study.

Background: The role of vitamin D in increased mortality with SARS-COV-2 virus, namely, COVID-19, remains uncertain. We analysed all the patients who were treated as COVID-19-positive with or without a positive swab and were tested for vitamin D levels.

Methods: This was a retrospective, study involving 1226 patients swabbed for SARS-CoV-2 between the 10 February 2020 and 1 May 2020 at two hospitals of East Sussex Healthcare NHS Trust.

A Retrospective Observational Study: Is Absolute Lymphocyte Count a Prognostic Marker in COVID-19?

Aim Our study aimed to find a correlation between low absolute lymphocyte count and COVID-19-related mortality. Methods This study followed a retrospective observational cohort design to analyze the data of patients who presented with symptoms and signs of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), at the Conquest Hospital and Eastbourne District General Hospital in East Sussex, United Kingdom, between February 10, 2020 and May 1, 2020, retrospectively. Survival and mortality for the first 30 days and comorbidities were analyzed for all patients who were tested for COVID-19 irrespective of swab results and had blood lymphocyte levels taken at the time of their visit to the ED and their data were analyzed for statistical significance.

Effect of Pre-Heating Prior to Low Temperature 0.1 µm-Microfiltration of Milk on Casein-Whey Protein Fractionation.

During skim milk microfiltration (nominal pore size of 0.1 µm) at 10 °C, the whey protein purity in the permeate is reduced by an enhanced serum casein permeation, primarily of β-casein. To decrease casein permeation, the possibility of a pre-heating step under pasteurization conditions before the filtration step was investigated, so as to shift the equilibrium from soluble serum casein monomers to impermeable micellar casein.

Culturally appropriate vegetables and economic development. A contextual analysis.

This paper examines the implications of the demand for ethno-cultural vegetables (ECV) by South-Asians, the largest cultural group in the Greater Toronto Area (GTA), on their potential for Ontario agricultural economic development and significant consumer health benefits. A conceptual framework is presented to explain the relationship among factors such as change in demographics, demand for locally produced ECV and both the potential agricultural and health benefits. Analysis of cross-sectional data collected in 2009 also indicates that the respondents have certain characteristics that are pertinent to understanding why they shop in particular stores and their perceptions about what constitutes quality.
