Роль питания и кишечного микробиома в развитии множественной миеломы и ее болезней-прекурсоров.

Множественная миелома (ММ) — вторая по распространенности гематологическая гелингология, характеризующаяся нерегулируемым моноклонным распространением в костном мозге. Моноклональная гаммопатия неопределённого значения (MMUS) и мрачная миелома (SMM) являются предмалярными условиями, которые могут развиваться до MM. Определение факторов этиологического риска для ММ и его болезней-прекурсоров имеет решающее значение для профилактики. Ожирение, питание, уровень витамина D и изменение кишечного микробиота были определены в качестве факторов образа жизни, влияющих на риск MM и MGUS. При возникновен

Факторы, связанные с содержанием витамина D у монгольских пациентов с множественным склерозом.

ЦЕЛЬ: Множественный склероз (МС) вызывается генетическими и экологическими факторами. Витамин D был определен в качестве фактора экологического риска, причем в широтах, расположенных дальше от экватора, отмечается более высокий уровень его распространенности. В Монголии при температуре 45°N воздействие солнечного света ограничено, что повышает риск для населения в связи с дефицитом витамина D. ЦЕЛИ: Сопоставление уровней содержания витамина D среди лиц с НР (ПМК) и лиц, не имеющих НР, и выявление факторов, связанных с низким содержанием витамина D. Мы изучили связи с уровнями витамина D, испол

Association of Vitamin D Receptor Gene Polymorphisms and Hypovitaminosis D with Reduced Bone Mineral Density in Survivors of Childhood Leukemia: A Study in Algerian Patients.

Survivors of childhood leukemia are at increased risk of long-term skeletal complications, including reduced bone mineral density (BMD). Vitamin D deficiency and genetic variations in the vitamin D receptor (VDR) gene are important factors influencing bone health, yet their combined effects remain insufficiently studied, particularly in North African populations. This case-control study included 130 survivors of childhood acute lymphoblastic leukemia (ALL) in remission (age range: 5-26 years) and 110 age- and sex-matched healthy controls recruited from Beni Messous Hospital. BMD was assessed a

Prevalence of potential underlying aetiology of macrocytic anaemia in Dutch general practice.

BACKGROUND: Macrocytic anaemia (MCV ≥ 100 fL) is a relatively common finding in general practice. However, literature on the prevalence of the different causes in this population is limited. The prevalence of macrocytic anaemia and its underlying aetiology were analysed in a general practice population. The potential effect of the different aetiology on survival was also evaluated. METHODS: Between the 1st of February 2007 and the 1st of February 2015, patients aged 50 years or older and presenting to their general practitioner with a newly diagnosed anaemia, were included in the study. Anaem

High-Dose Vitamin C in Advanced-Stage Cancer Patients.

High-dose intravenously administered vitamin C (IVC) is widely used in cancer patients by complementary and alternative medicine practitioners. The most frequent indications for IVC therapy result from the belief in its effectiveness as a potent anti-cancer agent which additionally enhances chemosensitivity of cancer cells and reduces chemotherapy-related toxicities and fatigue intensity. In this narrative review, we decided to deal with this issue, trying to answer the question whether there is any scientific evidence supporting the rationale for application of high-dose IVC therapy in advanc

Trying to Solve the Puzzle of the Interaction of Ascorbic Acid and Iron: Redox, Chelation and Therapeutic Implications.

Role of Vitamin D Replacement on Health Related Quality of Life in Hospitalized Patients with "Acute Exacerbation of Chronic Obstructive Pulmonary Disease".

Burden of Chronic Obstructive Pulmonary Disease (COPD) is substantial and increasing in the world. There are controversial reports regarding vitamin D supplementation in COPD. We investigated relationship between vitamin D3 (Cholecalciferol) supplementation with Health Related Quality of Life (HRQOL) and symptom recovery in AECOPD patients with concurrent Vitamin D Deficiency (VDD). A placebo-controlled randomized clinical trial was designed. AECOPD patients with VDD were randomly allocated to receive either vitamin D 300,000 IU (n = 35) or placebo (n = 35) by intramuscular injection. Primary

The Interplay between Immune System and Microbiota in Osteoporosis.

Osteoporosis is a disease characterized by low bone mass and alterations of bone microarchitecture, with an increased risk of fractures. It is a multifactorial disorder that is more frequent in postmenopausal women but can be associated to other diseases (inflammatory and metabolic diseases). At present, several options are available to treat osteoporosis trying to block bone reabsorption and reduce the risk of fracture. Anyway, these drugs have safety and tolerance problems in long-term treatment. Recently, gut microbiota has been highlighted to have strong influence on bone metabolism, becom
