In the last few decades many new anticoagulants (i.e direct thrombin and factor ten inhibitors) have been introduced with efficacy that rivals older drugs in the treatment of venous thromboembolism (VTE). However, for all their success, management of patients with recurrent thromboembolic events is still a challenging clinical scenario and not well addressed in the literature. We report the case of a young female with recurrent thromboembolisms in spite of using both newer agents and more conventional therapies...

Generally, licensed drug-dosing recommendations for chemotherapy are based on results from clinical trials in which subjects are usually of relatively normal body size, middle-aged, and are relatively racially homogeneous, with minimal comorbidity and specific tumor characteristics. Very few nontrial patients meet these characteristics, resulting in clinical practice having to extrapolate dosing recommendations to the specific patient. There is insufficient research on the impact of obesity-associated physiological changes prevalent in patients with common cancers on standard pharmacokinetic and pharmacodynamic parameters...

PURPOSE OF REVIEW: Atherosclerosis is now considered a chronic inflammatory disease. Oxidative stress induced by generation of excess reactive oxygen species has emerged as a critical, final common mechanism in atherosclerosis. Reactive oxygen species (ROS) are a group of small reactive molecules that play critical roles in the regulation of various cell functions and biological processes. Although essential for vascular homeostasis, uncontrolled production of ROS is implicated in vascular injury...

HIV infection and antiretroviral therapy (ART) treatment exert diverse effects on adipocytes and stromal-vascular fraction cells, leading to changes in adipose tissue quantity, distribution, and energy storage. A HIV-associated lipodystrophic condition was recognized early in the epidemic, characterized by clinically apparent changes in subcutaneous, visceral, and dorsocervical adipose depots. Underlying these changes is altered adipose tissue morphology and expression of genes central to adipocyte maturation, regulation, metabolism, and cytokine signaling...

The emergence of novel pathogenic strains with increased antibacterial resistance patterns poses a significant threat to the management of infectious diseases. In this study, we aimed at utilizing the subtractive genomic approach to identify novel drug targets against Salmonella enterica subsp. enterica serovar Poona strain ATCC BAA-1673. We employed in silico bioinformatics tools to subtract the strain-specific paralogous and host-specific homologous sequences from the bacterial proteome. The sorted proteome was further refined to identify the essential genes in the pathogenic bacterium using the database of essential genes (DEG)...

The genome sequence of V. cholerae O1 Biovar Eltor strain N16961 has revealed a putative antibiotic resistance (var) regulon that is predicted to encode a transcriptional activator (VarR), which is divergently transcribed relative to the putative resistance genes for both a metallo-β-lactamase (VarG) and an antibiotic efflux-pump (VarABCDEF). We sought to test whether these genes could confer antibiotic resistance and are organised as a regulon under the control of VarR. VarG was overexpressed and purified and shown to have β-lactamase activity against penicillins, cephalosporins and carbapenems, having the highest activity against meropenem...

In randomized controlled trials (RCTs), more intensive glucose control in patients with type 2 diabetes leads to a modest (9%) reduction in major cardiovascular events (MACE), associated with a 20% reduction of kidney events and 13% reduction of eye events. The FDA issued guidance in 2008 led to the conduct of numerous cardiovascular outcomes (CVOT) trials to assess cardiovascular safety of new antihyperglycemic therapies in patients with type 2 diabetes. The results of these trials show that insulin glargine, three different dipeptidyl peptidase-4 (DPP-4) inhibitors (saxagliptin, alogliptin, and sitagliptin) and lixisenatide (a glucagon like peptide-1 receptor agonist) produce no significant difference in CVOT when compared with usual care or placebo...

REVIEW

Drug-eluting stents (DES) have reached a high safety and efficacy profile, becoming the best option for percutaneous coronary interventions (PCI) based revascularization. However, despite their optimal performance, a few concerns remain regarding their use, mainly due to permanent caging of the vessels and its consequences, first of all late stent thrombosis (ST). Bioresorbable scaffolds (BRS) aim to overcome these issues. The results achieved in randomized controlled trials (RCT) by the first generation of poly-L-lactic acid (PLLA) based scaffolds were promising at 1 year, but the first long term reports (albeit flawed by non-optimal implantation technique) have been disappointing, showing, for instance, an increased risk of ST and target vessel myocardial infarction (TV-MI)...

Small vessels with coronary artery disease (CAD) are at high risk of restenosis, despite the use of drug-eluting stents (DESs). Drug-coated balloon (DCB) therapy offers a viable alternative to DESs for the management of small vessel CAD. The literature regarding the use of DCBs in lieu of the newer generation DESs to treat small vessel CAD is controversial.

Clinically available antifungals for the treatment of invasive fungal infections primarily target either ergosterol in the fungal cell membrane or 1,3-β-D-glucan in the fungal cell wall. These classes include the polyene amphotericin B, the triazoles, and the echinocandins. Although newer antifungals and improved formulations of others have advanced our ability to treat patients with invasive mycoses, these drugs are often limited by toxicities, drug interactions, and the need for intravenous administration...

New-generation drug-eluting stents (DES) represent the current standard of care in patients undergoing percutaneous coronary intervention (PCI). Biodegr adable polymer DES (BP-DES) were recently developed to overcome current limitations of newer-generation durable polymer DES (DP-DES) attributed to sustained inflammatory responses induced by permanent polymers. The Orsiro DES (Biotronik AG, Bülach, Switzerland) is a novel thin-strut cobalt-chromium sirolimus-eluting stent with biodegradable polymer that features some of the latest developments in DES technology...

REVIEW
Jason E Hawkes, Tom C Chan, James G Krueger
Psoriasis is caused by a complex interplay between the immune system, psoriasis-associated susceptibility loci, autoantigens, and multiple environmental factors. Over the last 2 decades, research has unequivocally shown that psoriasis represents a bona fide T cell-mediated disease primarily driven by pathogenic T cells that produce high levels of IL-17 in response to IL-23. The discovery of the central role for the IL-23/type 17 T-cell axis in the development of psoriasis has led to a major paradigm shift in the pathogenic model for this condition...

Despite our increasing understanding of the pathophysiology underlying chronic or maladaptive pain, there is a significant gap in our ability to diagnose and treat the condition in domestic cats. Newer techniques being used to identify abnormalities in pain processing in the cat include validated owner questionnaires, measurement of movement and activity, and measurement of sensory thresholds and somatomotor responses. While some data are available evaluating possible therapeutics for the treatment of chronic pain in the cat, most data are limited to normal cats...
