Acest document oferă o recomandare comună a Federației Europene de Chimie Clinică și Medicină de Laborator (EFLM), Grupului de lucru pentru faza preanalitică (WG-PRE) și Grupului de lucru din America Latină pentru Faza preanalitică (WG-PRE-LATAM) al Confederației Americii Latine de Biochimie Clinică (COLABIOCLI) pentru recoltarea sângelui venos. Documentul oferă îndrumări asupra cerințelor pentru asigurarea fap...

The pro-proliferative effect of insulin in human breast epithelial DMBA-transfo...

Type 2 diabetes mellitus (T2DM) is linked to an increased risk of breast cancer. We aimed to investigate how T2DM-associated characteristics (high levels of glucose, insulin, leptin, inflammatory mediators and oxidative stress) influence breast cancer carcinogenesis, in DMBA-treated (MCF-12ADMBA) and non-treated breast epithelial (MCF-12A) cell lines. Insulin (50 nM) promotes cell proliferation, 3H-DG uptake an...

Unveiling the Metabolic Effects of Glycomacropeptide

For many years, the main nitrogen source for patients with phenylketonuria (PKU) was phenylalanine-free amino acid supplements. Recently, casein glycomacropeptide (GMP) supplements have been prescribed due to its functional and sensorial properties. Nevertheless, many doubts still persist about the metabolic effects of GMP compared to free amino acids (fAA) and intact proteins such as casein (CAS). We endeavour...

Clinicians' and laboratory medicine specialists' views on laboratory demand man...

Background: Laboratory tests are an essential aspect of current medical practice and their use has grown exponentially. Several studies however have demonstrated inappropriate use of laboratory testing. This inappropriateness can lead to delayed or wrong diagnosis, negatively impacting patient safety and an increase in health care expenditure. The aim of the present small-scale survey was to obtain information ...

Time-dependence of cardiac biomarker levels in newborns with congenital heart d...

Urinary fibrogenic cytokines ET-1 and TGF-beta 1 are associated with urinary an...

BACKGROUND:Fibrogenic cytokines are recognized as putative drivers of disease activity and histopathological deterioration in various kidney diseases. We compared urinary transforming growth factor β1 (U-TGF-β1) and endothelin 1 (U-ET-1) levels across body mass index classes and assessed their association with the level of urinary angiotensinogen (U-AGT), a biomarker of intrarenal renin-angiotensin-aldosterone ...

Vitamin D levels and cardiometabolic risk factors in Portuguese adolescents

BACKGROUND: Growing evidence suggests a possible association between low vitamin D levels and increased cardiovascular risk. However, research regarding the period of adolescence is scarce. We aimed to evaluate the association of vitamin D, intake and serum 25(OH)D levels, with cardiometabolic risk factors in 13-year-old adolescents. METHODS: We conducted a cross-sectional analysis of 1033 adolescents evaluated...

Normalization of glomerular filtration rate in obese children

BACKGROUND:Glomerular filtration rate (GFR) is conventionally indexed to body surface area (BSA), but this may lead to biased results when applied to subjects of abnormal body size. The aim of our study was to examine the impact of normalization to the BSA and alternative body size descriptors on measured and estimated GFR in overweight and obese children. METHODS:This was a cross-sectional study of 313 childre...

Prevalence, incidence and risk factors for Helicobacter pylori infection in a c...

Background: Helicobacter pylori infection is acquired mainly during childhood, but it may occur throughout life. Understanding the determinants of infection at different ages is essential to clarify dynamics of H. pylori related diseases and to design preventive strategies. Aim: To estimate the prevalence of H. pylori infection at the age of 13 and the incidence after a 3-year follow-up and to identify risk fac...

Characterization of rat heart alkaline phosphatase isoenzymes and modulation of...

Alkaline phosphatase (ALP) is important in calcification and its expression seems to be associated with the inflammatory process. We investigated the in vitro acute effects of compounds used for the prevention or treatment of cardiovascular diseases on total ALP activity from male Wistar rat heart homogenate. ALP activity was determined by quantifying, at 410 nm, the p-nitrophenol released from p-nitrophenylpho...
