Book Description
Cette étude visait à évaluer les relations entre le statut et la supplémentation en vitamine D (VitD) et la gravité de la maladie COVID-19 chez les personnes âgées (âge moyen de 78 ans) hospitalisées pour COVID-19. Nous avons mené une étude de cohorte rétrospective observationnelle auprès de 228 patients âgés hospitalisés pendant la première vague de la pandémie de la COVID-19. Les résultats étaient la mortalité à l'hôpital secondaire à la COVID-19 ou une forme sévère de la maladie. Une analyse de régression logistique a été réalisée pour vérifier si la supplémentation en vitamine D avant l'hospitalisation était indépendamment associée à la gravité. Dans cette étude, 46% des patients ont développé une forme sévère et la mortalité globale à l'hôpital était de 15%. Soixante-six (29 %) patients ont reçu un supplément de vitamine D au cours des trois mois précédant le début de l'infection. De plus, la supplémentation en vitamine D était associée à un nombre moindre de formes graves de la COVID-19 (OR = 0,426, p = 0,0135) et d'admissions en unité de soins intensifs (OR = 0,341, p = 0,0076). Comme prévu, l'âge >70 ans, le sexe masculin et l'IMC ≥ 35 kg/m2 étaient des facteurs de risque indépendants pour les formes sévères de la COVID-19. Aucune relation entre les taux sériques de 25(OH)D et la sévérité de la COVID-19 n'a été identifiée. Une supplémentation en Vitamine D prise au cours des 3 mois précédant le début de l'infection pourrait avoir un effet protecteur sur le développement des formes sévères de la maladie chez les personnes âgées.

Book Description
Bachelor Thesis from the year 2021 in the subject Medicine - Internal Medicine, grade: 1,5, , language: English, abstract: In recent years, the popularity of vitamin D has risen in the alternative medicine spectrum as a “universal” substance for all sorts of diseases. Although many of the claims cannot be backed by scientific evidence, strong evidence still demonstrates the beneficial effects of vitamin D for treating various conditions that are not directly related to hypovitaminosis. Currently, there is evidence that demonstrates that the supplementation of vitamin D can prevent or relieve upper respiratory infections and endemic influenza. Additionally, herpesviruses are responsive to treatments that incorporate vitamin D, and antibody titers seem to be higher in individuals with higher vitamin D levels. For viral hepatitis, viral DNA load and seasonal fluctuating vitamin D levels seem to correlate with each other. Regarding Covid-19, there is a clear correlation between the disease’s course and duration and vitamin D serum levels. However, it remains unclear whether low vitamin D levels can increase an individual’s susceptibility to Covid-19 or whether Covid-19 causes low vitamin D levels. Furthermore, it is unclear whether a part of Covid-19’s typical symptoms could be caused by a vitamin D deficiency. To uncover high-quality evidence regarding this topic, the author proposed a clinical trial to evaluate the effects of vitamin D supplementation on Covid-19 hospitalisation rates.

Book Description
Nutrigenetics: Applying the Science of Personal Nutrition provides a fully referenced, readable guide to understanding the rationale and importance of nutrigenetic applications and explains why single nutrition recommendations will not fit everybody or even a majority of modern humans. This books explains how genetic variation shapes individual nutrition requirements and sensitivities, presents questions to ask about reported gene-nutrient interactions, and what needs to be done before putting nutrigenetic tests to practical use. This book blends key concepts from the fields of genetics, biochemistry, epidemiology, public health, and clinical medicine to give a rich perspective on the genetically diverse nutritional needs and sensitivities of individuals in health and disease. A steadily increasing number of people order genetic tests to find out what they should eat for better health, well being and performance, and an even greater number asks their healthcare providers about such tests. Most of the currently offered tests are not grounded in current knowledge, often absurdly so, but few professionals can explain why they are misguided. On the other hand, there are more evidence-supported genetic variants that can guide nutrition decisions, but again most healthcare providers know little about them, much less use them in their daily practice. There is a great need for a solidly evidence-based yet accessible book that explains the science of nutrigenetics and provides the tools to evaluate new nutrigenetic tests. - Comprehensive coverage of the emerging science of nutritional genetics and its promise for individually tailored nutrition guidance - Presents practical examples to enhance comprehension and spur additional research - Offers a logical progression from what nutrigenetics is, to its possibilities in enhancing health

Book Description
At the time of this study India had the third highest COVID-19 infection rate in the world after the US and Brazil, but that statistic was in flux due to rapidly changing variables and, therefore, it seemed an appropriate setting for a supplementation study. Following a successful first trial of vitamin C, D and zinc supplementation in 2020 with the staff at a small medical clinic in India, a second opportunity arose to continue the trial from January-March 22nd due to an urban coronavirus outbreak during the beginning of March 2021. It resulted in nearly a doubling of COVID-19 cases within the country in two weeks (March 8th - March 22nd) possibly due to the new, highly infectious, Indian Delta variant with multiple mutations and/or other international variants like the UK Alpha variant that were also present in the population by this time. As a result, a nighttime curfew and other restrictions were imposed for the whole month. An outbreak also occurred locally in a nearby city where the incidence of coronavirus cases increased and this happened prior to vaccination of the medical staff as part of the country,Äôs universal inoculation campaign for healthcare workers, which began in January 2021 (one clinic clerk who travelled to the district civil hospital to receive the vaccine during the course of this second study was disqualified; all other clinic staff were inoculated after March 22nd). Although the clinic had closed during the first lockdown between March and mid-June 2020, it remained open to the public for this second wave in March 2021. During this period, the medical & non-medical staff continued following the same supplementation regimen as they had in July-December 2020 for Part I of this trial with positive results. Once again, in Part II of the trial, there were no COVID-19 cases recorded among any of the staff members at the clinic, which is situated in a rural community. It was concluded that targeted vitamin/mineral supplementation may be a useful addition to the anti-COVID-19 arsenal for health professionals at higher than average risk of infection.

Book Description
Dyslipidemia, and particularly hypercholesterolemia, remains a main cardiovascular disease risk factor, partly reversible with the improvement of life-style, including dietary, habits. Even when a pharmacological treatment is begun, dietary support to lipid-lowering is always desired. This book will provide a selection of new evidence on the possible lipid-lowering effects of some dietary and medicinal plant components, reporting some interesting reviews, experimental data and results from clinical trials. The book is adapted for experts in nutrition but also for all scientists involved in cardiovascular disease prevention.
