BACKGROUND The association between serum selenium levels and type 2 diabetes mellitus (T2DM) is controversial. We performed a systematic review and non-linear dose-response meta-analysis of observational studies to investigate the association in the present study. METHODS A comprehensive literature search was conducted using MEDLINE and EMBASE databases. A pooled odds ratio (OR) and related 9...
association of serum zinc and selenium concentration in the etiology of miscarriage in iranian women
background: adequate serum level of zinc and selenium is required for normal metabolic performance and successful fertility. the present study was conducted to evaluate the association of serum zinc and selenium in early stage of gestation with the incidence of miscarriage in iranian women. materials and methods: one hundred two females were studied in three matched groups. group 1 consisted of...
background: gastric cancer (gc) is the most common gastrointestinal cancer in iran. helicobacter pylori (h. pylori) accounts as one of the main risk factors for gastric non-cardia cancer (gncc). it is suggested that high serum selenium level may have a protective role in gncc. in this cross-sectional study, we determined the serum se level and the status of h. pylori infection in two population...
Introduction & Objective : In recent studies on cardiovascular diseases, selenium has received increasing attention. It is argued that selenium can protect the cells by inhibiting peroxidation of lipids and tissue damage and can increase the immunological mechanisms by inhibiting mutagenic processes. The aim of this study was to determine the serum selenium level and its relation to myocardial ...
BACKGROUND Selenium, an essential trace element involved in defense against oxidative stress, may prevent cancer and cardiovascular disease. We evaluated the association between selenium levels and all-cause and cause-specific mortality in a representative sample of US adults. METHODS Serum selenium levels were measured in 13,887 adult participants in the Third National Health and Nutrition E...
Serum selenium has been implicated as a risk factor for lung cancer, but the issue remains unsettled. In a cohort of 3,333 males aged 53-74 yrs, we tested the hypothesis that a low serum selenium concentration would be associated with an increased risk of lung cancer mortality. Over 16 yrs, 167 (5.1%) subjects died of lung cancer: 48 (5.0%) out of 965 with low serum selenium (0.4-1.0 μmol · L(-...
background: pemphigus vulgaris is a life threatening, blistering skin disease. it is an autoimmune abnormality. due to involvement of oral cavity and pharynx, patients are at risk of nutrients deficiency. the aim of this study was to evaluate the status of selenium, copper, and zinc in these patients. methods: in a case-control study, 43 newly diagnosed pemphigus vulgaris patients were compared...
Low selenium status draws much attention because of the possible involvement in the etiology of cardiovascular disease (CVD). Hyperlipidmia or dyslipidemia, a very important risk factor for CVD, occurs frequently in middle-aged Koreans. While selenium deficiency is supposed to aggravate blood lipid profiles, it has been shown that selenium status diminishes with advanced age. However, little is...
BACKGROUND Low serum selenium has been associated with lower CD4 counts and greater mortality among HIV-1-seropositive individuals, but most studies have not controlled for serum albumin and the presence of an acute phase response. METHODS A cross-sectional study was conducted to evaluate relationships between serum selenium concentrations and CD4 count, plasma viral load, serum albumin, and ...
A case-cohort study, within a multi-country trial of antiretroviral therapy (ART) efficacy (Prospective Evaluation of Antiretrovirals in Resource Limited Settings (PEARLS)), was conducted to determine if pre-ART serum selenium deficiency is independently associated with human immunodeficiency virus (HIV) disease progression after ART initiation. Cases were HIV-1 infected adults with either clin...
