The use of counterfeit or substandard medicines can have an important health impact, resulting in therapeutic failure, be toxic or even cause death. Anabolic steroids are a frequent target for counterfeiters worldwide, being the second most frequent counterfeited class in Brazil. The aims of this work were to optimize and validate a GC-MS method for the quantitative determination of anabolic steroids in tablet, aqueous suspension and oil solution forms, and to analyze pharmaceutical products sent to Brazilian Federal Police (BFP) for forensic analysis...

Melamine toxicity has recently attracted worldwide attention as it causes renal failure and the death of humans and animals. Therefore, developing a simple, fast and sensitive method for the routine detection of melamine is the need of the hour. Herein, we have developed a selective colorimetric method for the detection of melamine in milk samples based upon in-situ formation of silver nanoparticles (AgNPs) via tannic acid. The AgNPs thus formed were characterized by UV-Visible spectrophotometer, transmission electron microscope (TEM), zetasizer and dynamic light scattering (DLS)...

BACKGROUND: The spacing of pregnancies has a positive impact on maternal and newborn health. The progestin contraceptive implant, which is a long-acting, reversible method of contraception, has a well-established low failure rate that is compatible with tubal sterilization. The standard provision of contraceptive methods on the first postpartum visit may put some women at risk of unintended pregnancy, either due to loss to follow-up or having sexual intercourse prior to receiving contraception...

AIMS: Heart failure (HF) is frequent in type 2 diabetes (T2D) and several glucose-lowering medications may increase HF risk. In the SAVOR-TIMI trial, patients on Saxagliptin experienced a 27% higher risk of hospitalisation for HF (HHF). In a retrospective study on 127,555 patients, we showed that DPP-4i therapy was associated with a lower HHF risk than sulphonylurea (SU) therapy. We herein re-analyzed such data to evaluate intraclass differences among DPP-4i and SU. MATERIALS AND METHODS: We included T2D patients initiating DPP-4i or SU alone or in combination with metformin...

Most algorithms for type 2 diabetes mellitus (T2DM) do not recommend treatment escalation until glycated haemoglobin (HbA1c) fails to reach the recommended target of 7% (53 mmol/mol) within approximately 3 months on any treatment regimen ('treat to failure'). Clinical inertia and/or poor adherence to therapy contribute to patients not reaching glycaemic targets when managed according to this paradigm. Clinical inertia exists across the entire spectrum of anti-diabetes therapies, although it is most pronounced when initiating and optimizing insulin therapy...

Uterus transplantation is a vascularized composite allograft transplantation. It allows women who do not have a uterus to become pregnant and deliver a baby. In this paper we analyze the first 5 cases of Living Donor Uterus Transplantation performed in the US. The first 3 recipients lost their uterus grafts at day 14, 12 and 6 after transplant. Vascular complications, related to both inflow and outflow problems, were identified as the primary reason for the graft losses. Two recipients, 6 and 3 months post-transplant have functioning grafts with regular menstrual cycles...

INTRODUCTION: In patients with heart failure (HF) and reduced ejection fraction, increased heart rate (HR) is an independent risk factor for adverse outcomes. In systolic HF treatment with the If inhibitor ivabradine trial (SHIFT), Ivabradine improved survival when added to conventional treatment including β-blockers. However, the extent of benefit in the real world is unclear. We examined the characteristics of patients on guideline-directed therapy and determined who had SHIFT-like characteristics...

Cardiac Magnetic Resonance Imaging has become a cornerstone in the evaluation of heart failure. It provides a comprehensive evaluation by answering all the pertinent clinical questions across the full pathological spectrum of heart failure. Nowadays, CMR is considered the gold standard in evaluation of ventricular volumes, wall motion and systolic function. Through its unique ability of tissue characterization, it provides incremental diagnostic and prognostic information and thus has emerged as a comprehensive imaging modality in heart failure...

Patients with heart failure often exhibit electrolyte abnormalities, such as hyponatremia or hypokalemia/hyperkalemia. Although not as common as the other electrolyte disturbances observed in patients with heart failure, phosphate imbalance is also of high importance in this population. The aim of this review is to present the mechanisms of low or high phosphate serum levels in patients with heart failure and its role in the pathogenesis and progression of heart dysfunction. Hypophosphatemia in patients with heart failure may be the result of co-existing electrolyte and acid-base abnormalities, pharmacological treatments, decreased intestinal absorption or secondary to sympathetic nervous system activation and co-morbidities, such as diabetes mellitus or heavy alcohol consumption...

Despite the introduction of multiple new pharmacological agents over the past three decades in the field of heart failure (HF), overall prognosis remains poor. Hyponatremia is prevalent in HF patients and has been suggested as a contributor to poor response to standard therapy. Elevated levels of arginine vasopressin (AVP), a peptide hormone produced in the hypothalamus, play a role in development of hyponatremia, and AVP and its surrogate, copeptin, are related to changes in osmolality, hemodynamics, neuro-hormones as well as in overall outcome in HF patients...

BACKGROUND: Several fatal cases of bodybuilders, following a myocardial infarction after long exposure to androgenic-anabolic steroids (AAS), are reported. In recent years, evidence has emerged of cases of heart failure related to AAS consumption, with no signs of coronary or aorta atherosclerosis. This study aims to further investigate the pathogenesis of the ventricular AAS-related remodeling performing immunohistochemistry (IHC). METHOD: In order to examine innate immunity activity and myocytes and endothelial cell apoptosis, IHC analyses were performed on heart tissue of two cases of bodybuilders who died after years of supratherapeutic use of metelonone and nandrolone and where no atherosclerosis or thrombosis were found, using the following antibodies: anti-CD68, anti-iNOS, anti-CD163, anti-CD 15, anti-CD8, anti-CD4, anti-HIF1 α, and in situ TUNEL staining...
