BACKGROUND: Neuraminidase inhibitors are effective for the treatment of acute uncomplicated influenza. However, there is an unmet need for intravenous treatment for patients admitted to hospital with severe influenza. We studied whether intravenous zanamivir was a suitable treatment in this setting. METHODS: In this international, randomised, double-blind, double-dummy, phase 3 trial, we recruited patients aged 16 years or older with severe influenza admitted to 97 hospitals from 26 countries...

Several physiological events in the brain are regulated by the endocannabinoid system (ECS). While synthetic cannabinoid receptor (CBr) agonists such as WIN55,212-2 act directly on CBr, agents like URB597, a fatty acid amide hydrolase (FAAH) inhibitor, induce a more "physiological" activation of CBr by increasing the endogenous levels of the endocannabinoid anandamide (AEA). Herein, we compared the pre- and post-treatment efficacy of URB597 and WIN55,212-2 on different endpoints evaluated in the toxic model produced by the mitochondrial toxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in mice...

The discovery of reliable biomarkers to predict efficacy and toxicity of anticancer drugs remains one of the key challenges in cancer research. Despite its relevance, no efficient study designs to identify promising candidate biomarkers have been established. This has led to the proliferation of a myriad of exploratory studies using dissimilar strategies, most of which fail to identify any promising targets and are seldom validated. The lack of a proper methodology also determines that many anti-cancer drugs are developed below their potential, due to failure to identify predictive biomarkers...

BACKGROUND: Systemic blockade of TNF-α in Rheumatoid arthritis (RA) with insulin resistance (IR) seems to produce more improvement in insulin sensitivity in normal weight patients with RA than in obese patients with RA, suggesting that systemic-inflammation and obesity are independent risk factors for IR in RA patients. OBJECTIVES: To evaluate the insulin resistance in: normal weight patients with RA (RA NW), overweight patients with RA (RA OW), obese RA patients (RA OB), and matched control subjects with normal weight (NW) and obesity (OB); and its association with major cytokines involved in the pathogenesis of the disease...

Infection, relapse, and GVHD can complicate allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although the effect of poor immune recovery on infection risk is well-established, there are limited data on the effect of immune reconstitution on relapse and survival, especially following T-cell depletion (TCD). To characterize the pattern of immune reconstitution in the first year after transplant and its effects on survival and relapse, we performed a retrospective study in 375 recipients of a myeloablative TCD allo-HSCT for hematologic malignancies...

BACKGROUND: Although the effects of probiotics on the immune system have been extensively evaluated under disease states, their role in healthy situations remains unclear, since changes are hardly expected under immunological homeostasis. EFSA indicates that vaccination protocols could be used to evaluate the potential role of probiotics to improve the immune response against antigen challenges. The aim of the study was to evaluate the effect of Lactobacillus coryniformis CECT5711 (Lc) on the specific immunity of healthy volunteers undergoing vaccination with Hepatitis A virus (HAV)...

AIMS: Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C) is often associated with desmosomal mutations. Recent studies suggest an interaction between the desmosome and sodium channel protein Nav1.5. We aimed to determine the prevalence and biophysical properties of mutations in SCN5A (the gene encoding Nav1.5) in ARVD/C. METHODS AND RESULTS: We performed whole-exome sequencing in six ARVD/C patients (33% male, 38.2 ± 12.1 years) without a desmosomal mutation...

In order to fertilize, spermatozoa must undergo physiological and biochemical changes during their transit along the female reproductive tract before reaching and fusing with the oocyte, process known as capacitation. Sperm modifications associated with capacitation are modulated by their interaction with molecules present in the female reproductive tract. During the woman fertile window, some reproductive hormones reach their maximum concentrations in serum, such as the luteinizing hormone (LH). Since spermatozoa preparing to fertilize may be exposed to LH, the purpose of this work was to study the effects of this hormone on intracellular Ca(2+) concentrations ([Ca(2+)]i), protein tyrosine phosphorylation, sperm motility and acrosome reaction under capacitating conditions...

Different classes of Kv1 potassium channels have different trafficking patterns despite having very similar amino acid sequences. Two amino acids responsible for these differences have been identified in the outer pore turret region of Kv1.1 and Kv1.4. Here we tested a series of substitutions at these two determinants on Kv1.4. All P506 substitutions tested resulted in a significant decrease in surface protein, total protein, and protein half-life, indicating that proline is required at 506 to stabilize protein conformation and increase trafficking to the cell surface...

The under-representation of ethnic minority participants, who are more likely to be socially disadvantaged in biomedical research, limits generalizability of results and reductions in health disparities. To facilitate investigations of how social disadvantage "gets under the skin," this pilot study evaluated low-intensity methods for collecting hair and saliva samples from multiethnic breast cancer survivors (N = 70) and analysis of biomarkers of chronic stress (cortisol levels) and biological age (telomere length)...

BACKGROUND: Cryptococcus is a rare cause of ventriculoperitoneal shunt infection, with a variable clinical presentation. Hence, diagnosis and therapeutic management of this entity is challenging. CASE DESCRIPTION: we herein describe the first reported case of cryptococcal ventriculoperitoneal shunt (VPS) infection in an HIV-infected subject with an excellent immunovirological status, with an abdominal mass as the only clinical sign at presentation. Microbiological diagnosis was confirmed when Cryptococcus neoformans was isolated in 4 cerebrospinal fluid samples on different days...

The extent of inbreeding depression and the magnitude of heterozygosity-fitness correlations (HFC) have been suggested to depend on the environmental context in which they are assayed, but little evidence is available for wild populations. We combine extensive molecular and capture-mark-recapture data from a blue tit (Cyanistes caeruleus) population to (1) analyze the relationship between heterozygosity and probability of interannual adult local recruitment and (2) test whether environmental stress imposed by physiologically suboptimal temperatures and rainfall influence the magnitude of HFC...

Systemic sclerosis (SSc) is a rare autoimmune disease with the highest case-fatality rate of all connective tissue diseases. Current efforts to determine patient response to a given treatment using the modified Rodnan skin score (mRSS) are complicated by interclinician variability, confounding, and the time required between sequential mRSS measurements to observe meaningful change. There is an unmet critical need for an objective metric of SSc disease severity. Here, we performed an integrated, multicohort analysis of SSc transcriptome data across 7 datasets from 6 centers composed of 515 samples...

Ex vivo CD34+ selected T-cell depletion (TCD) has been developed as a strategy to reduce the incidence of graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Clinical characteristics, treatment responses, and outcomes of patients developing acute (a-) and chronic (c-) GVHD after TCD allo-HSCT have not been well established. We evaluated 241 consecutive patients (median age 57 years) with acute leukemia (n = 191, 79%) or myelodysplastic syndrome (MDS) (n = 50, 21%) undergoing CD34+ selected TCD allo-HSCT without post-HCST immunosuppression in a single institution...
