Fixed-dose combinations (FDC) have been developed to reduce the pill burden for hypertensive patients. Data on fixed-dose or free-dose (freeDC) ramipril/amlodipine (R/A) or candesartan/amlodipine (C/A) combination treatment initiation were assessed. 71 463 patients were prescribed R/A and 10 495 C/A. For both R/A and C/A, FDC patients were younger (both P < .001) and less comorbid. Prior MI (OR: 0.61 and 0.60), prior stroke (OR: 0.68 and 0.70) and CHD (OR: 0.68 and 0.64) were negatively associated with FDC use, whereas hyperlipidemia was positively associated (OR: 1...

BACKGROUND: Shorter-duration antibiotic treatment is sufficient for a range of bacterial infections, but has not been adequately studied for bloodstream infections. Our systematic review, survey, and observational study indicated equipoise for a trial of 7 versus 14 days of antibiotic treatment for bloodstream infections; a pilot randomized clinical trial (RCT) was a necessary next step to assess feasibility of a larger trial. METHODS: We conducted an open, pilot RCT of antibiotic treatment duration among critically ill patients with bloodstream infection across 11 intensive care units (ICUs)...

Severely obese patients undergoing bariatric surgery (BS) are at increased risk for venous thromboembolism (VTE). How standard low molecular weight heparin (LMWH) regimen should be adapted to provide both sufficient efficacy and safety in this setting is unclear. We aimed to compare the influence of four body size descriptors (BSD) on peak anti-Xa levels in BS obese patients receiving LMWH fixed doses to identify which one had the greatest impact. One hundred and thirteen BS obese patients [median body mass index (BMI), 43...

One of the most common and unwanted side effects during oral anticoagulant therapy (OAT) is bleeding complications. In rare cases, vitamin K antagonist (VKA)-related bleeding events are associated with mutations affecting the F9 propeptide at amino acid position 37 due to a substitution of alanine to either valine or threonine. Based on our actual cohort of 18 patients, we update the knowledge on this rare phenotype and its origin. A founder mutation for both variants was reconfirmed by haplotype analysis of intronic and extragenic short tandem repeat (STR) polymorphisms with a higher prevalence in Switzerland than in other regions of Europe...

Widespread expression of leptin and its receptor in developing cartilage and bone suggests that leptin may regulate bone growth and development in the fetus. Using micro-computed tomography, this study investigated the effects of exogenous leptin and leptin receptor antagonism on aspects of bone structure in the sheep fetus during late gestation. From 125-130 days of gestation (term ~145 days), chronically-catheterised singleton sheep fetuses were infused intravenously for five days with either saline (0.9% saline, n=13), recombinant ovine leptin at two doses (0...

Ionizing radiation (IR)-induced damage confers functional and conformational changes to nuclear chromatin associated with DNA single and double strand breaks. This leads to the activation of complex DNA repair machineries that aim to preserve the integrity of the DNA molecule. Since hetero- and euchromatin are differentially accessible to DNA repair pathways, local chromatin re-arrangements and structural changes are among the consequences of an activated DNA damage response. Using super-resolution localization microscopy (SRLM), we investigated the X-ray-induced repositioning of γ-H2AX and histone H3K9me3 heterochromatin marks in the nuclei of HeLa cells...

Amiodarone is a first-line antiarrhythmic for life-threatening ventricular fibrillation or ventricular tachycardia in children, yet little is known about its pharmacokinetics (PK) in this population. We developed a population PK (PopPK) model using samples collected via an opportunistic study design of children receiving amiodarone per standard of care supplemented by amiodarone PK data from the literature. Both study data and literature data were predominantly from infants < 2 years old, so our analysis was restricted to this group...

BACKGROUND: Patients with traumatic intracranial hemorrhage (TIH) anticoagulated with warfarin are at an increased risk of mortality. Fresh frozen plasma (FFP) and vitamin K have been the standard treatment for warfarin reversal; however, guidelines now recommend the use of prothrombin complex concentrate (PCC) for warfarin reversal in patients with life-threatening bleeding. Our protocol uses one vial (∼1000 units) of activated PCC (aPCC) for warfarin reversal, regardless of the weight or presenting international normalized ratio (INR)...

Worldwide, hepatocellular carcinoma (HCC) is the major subtype of primary liver cancers. HCC is typically diagnosed late in its course. With respect to cancer, the genomic actions of vitamin D are mediated through binding to the Vitamin D Receptor (VDR), which allows it to modulate the expression of genes in a cell-and tissue-specific manner. Epigenetics is a rapidly evolving field of genetic study applicable to HCC. Changes in DNA methylation patterns are thought to be early events in hepatocarcinogenesis...
