In addition to oxidative stress due to the increase of free radicals, estrogen deficiency is associated with changes in enzymatic activity, glutathione redox ratio (GSH/GSSG), and the content of oxidative markers such as malondialdehyde. Tibolone, a synthetic steroid, has been used as an elective treatment for the relief of menopausal symptoms. However, the acute effects of hormonal therapy with tibolone on metabolic parameters and oxidative stress markers associated with the first stages of estrogen deficiency are still unknown...

Background: Dairy fat consumed as cheese has different effects on blood lipids than that consumed as butter. It is unknown whether the effect is specific to fat interaction with other cheese nutrients (calcium, casein proteins), or to the cheese matrix itself. Objective: We aimed to test the effect of 6 wk daily consumption of ∼40 g dairy fat, eaten within macronutrient-matched food matrices, on markers of metabolic health, in overweight adults aged ≥50 y. Design: The study was a 6-wk randomized parallel intervention; 164 volunteers (75 men) received ∼40 g of dairy fat/d, in 1 of 4 treatments: (A) 120 g full-fat Irish cheddar cheese (FFCC) (n = 46); (B) 120 g reduced-fat Irish cheddar cheese + butter (21 g) (RFC + B) (n = 45); (C) butter (49 g), calcium caseinate powder (30 g), and Ca supplement (CaCO3) (500 mg) (BCC) (n = 42); or (D) 120 g FFCC, for 6 wk (as per A) (n = 31)...

The bioavailability of ivermectin is modulated by lipid-based formulations and membrane efflux transporters such as Breast Cancer Resistance Protein and P-glycoprotein (BCRP and P-gp). We have investigated the effect of oleic acid on the uptake of ivermectin in vitro using Caco-2 cells and in vivo in the intestines of wild-type mice. Complex micelles (M) with oleic acid induced a significant increase (e. g. for M3 was 7-fold, p≤0.001) in the uptake of the drug in a time-dependent manner with no involvement of cholesterol in the mechanism...

Aims: Evidence suggests an excess risk of non-thromboembolic major adverse cardiac events (MACE) associated with atrial fibrillation (AF), particularly in individuals free of overt coronary artery disease (CAD). Metabolic syndrome (MetS) increases cardiovascular risk in the general population, but less is known how it influences outcomes in AF patients. We aimed to assess whether MetS affects the risk of MACE in AF patients without overt CAD. Methods and results: This prospective, observational study enrolled 843 AF patients (mean-age, 62...

Anthropomorphic measures among type 1 diabetic patients are changing as the obesity epidemic continues. Excess fat mass may impact bone density and ultimately fracture risk. We studied the interaction between bone and adipose tissue in type 1 diabetes subjects submitted to two different clinical managements: (I) conventional insulin therapy or (II) autologous nonmyeloablative hematopoietic stem-cell transplantation (AHST). The study comprised 3 groups matched by age, gender, height and weight: control (C = 24), type 1 diabetes (T1D = 23) and type 1 diabetes treated with AHST (T1D-AHST = 9)...

With statins, the reported rate of adverse events differs widely between randomized clinical trials (RCTs) and observations in clinical practice, the rates being 1-2% in RCTs versus 10-20% in the so-called real world. One possible explanation is the claim that RCTs mostly use a run-in period with a statin. This would exclude intolerant patients from being included into RCTs and therefore favor a bias towards lower rates of intolerance.We here review data from RCTs with more than 1000 participants with and without a run-in period, which were included in the Cholesterol Treatment Trialists collaboration (CTTC)...

At the time of diagnosis, 20% of patients with colorectal cancer (CRC) present with metastasis. Among individuals with primary lesions, 50% of them will develop distant tumors with time. Therefore, early diagnosis and prediction of aggressiveness is crucial for therapy design and disease prognosis. Tumoral cells must undergo significant changes in energy metabolism to meet increased structural and energetic demands for cell proliferation, and metabolic alterations are considered to be a hallmark of cancer. Here, we present ABCA1, a regulator of cholesterol transport, as a new marker for invasion and colorectal cancer survival...

INTRODUCTION AND OBJECTIVES: To develop a predictive function of lifetime cardiovascular risk, including morbidity and mortality, in a healthy working population in Spain. METHODS: Retrospective cohort study. We selected healthy workers, aged 18 to 65 years, with no history of cardiovascular disease, who underwent a health assessment between 2004 and 2007. We used 70% of the cohort to develop the risk equation, and the remaining 30% to validate the equation. Four Cox proportional hazards models were constructed using cardiovascular events and competing events as dependent variables...
