Cardiovascular risk and white matter lesions after endocrine control of Cushing's syndrome.

Objective: Cushing's syndrome (CS) is associated with high cardiovascular risk. White matter lesions (WML) are common on brain magnetic resonance imaging (MRI) in patients with increased cardiovascular risk.

Aim: To investigate the relationship between cardiovascular risk, WML, neuropsychological performance and brain volume in CS.

Expression of IL-1α correlates with distant metastasis in patients with head and neck squamous cell carcinoma.

The presence of IL-1 in human cancers is associated with aggressive tumor biology but its prognostic value is unknown. We studied whether IL-1α expression is a prognostic marker of distant metastasis in patients with head and neck squamous cell carcinoma (HNSCC). IL-1α mRNA and protein levels were determined in tumor samples and cancer cell lines using RT-PCR and ELISA.

Management of direct-acting antiviral agent failures.

Failure to respond to the approved combinations of multiple direct-acting antiviral agents is relatively low in hepatitis C virus treatment registration studies, with rates of 1% to 7%, depending on the patients' baseline characteristics. In real life, failure is slightly higher, likely because of lower compliance. Treatment failures are usually related to relapse and less often to on-treatment viral breakthrough.

Untargeted metabolomics in doping control: detection of new markers of testosterone misuse by ultrahigh performance liquid chromatography coupled to high-resolution mass spectrometry.

The use of untargeted metabolomics for the discovery of markers is a promising and virtually unexplored tool in the doping control field. Hybrid quadrupole time-of-flight (QTOF) and hybrid quadrupole Orbitrap (Q Exactive) mass spectrometers, coupled to ultrahigh pressure liquid chromatography, are excellent tools for this purpose. In the present work, QTOF and Q Exactive have been used to look for markers for testosterone cypionate misuse by means of untargeted metabolomics.

Experimental drought and heat can delay phenological development and reduce foliar and shoot growth in semiarid trees.

Higher temperatures associated with climate change are anticipated to trigger an earlier start to the growing season, which could increase the terrestrial C sink strength. Greater variability in the amount and timing of precipitation is also expected with higher temperatures, bringing increased drought stress to many ecosystems. We experimentally assessed the effects of higher temperature and drought on the foliar phenology and shoot growth of mature trees of two semiarid conifer species.

Tenofovir discontinuation after long-term viral suppression in HBeAg negative chronic hepatitis B. Can HBsAg levels be useful?

Background: Recent studies have shown that antiviral treatment discontinuation is safe and associated with virologic remission in HBeAg-negative patients. However, the period of viral suppression and follow-up in these studies was relatively short.

Objectives: To investigate whether continuous viral suppression with tenofovir disoproxil fumarate for more than 7 years is associated with HBsAg loss and sustained response after treatment discontinuation and receiving a full course of hepatitis B vaccination.

Impaired decision making and delayed memory are related with anxiety and depressive symptoms in acromegaly.

Evaluation of cognitive function in acromegaly has revealed contradictory findings; some studies report normal cognition in patients with long-term cured acromegaly, while others show attention and memory deficits. Moreover, the presence of affective disorders in these patients is common. Our aim was to evaluate memory and decision making in acromegalic patients and explore their relationship with affective disorders like anxiety and depressive symptoms.

White matter alterations in the brains of patients with active, remitted, and cured cushing syndrome: a DTI study.

Background And Purpose: Cushing syndrome appears after chronic exposure to elevated glucocorticoid levels. Cortisol excess may alter white matter microstructure. Our purpose was to study WM changes in patients with Cushing syndrome compared with controls by using DTI and the influence of hypercortisolism.

An original phylogenetic approach identified mitochondrial haplogroup T1a1 as inversely associated with breast cancer risk in BRCA2 mutation carriers.

Introduction: Individuals carrying pathogenic mutations in the BRCA1 and BRCA2 genes have a high lifetime risk of breast cancer. BRCA1 and BRCA2 are involved in DNA double-strand break repair, DNA alterations that can be caused by exposure to reactive oxygen species, a main source of which are mitochondria. Mitochondrial genome variations affect electron transport chain efficiency and reactive oxygen species production.

Advances in 'omics' technology and targeted therapeutic molecules are together driving the incorporation of molecular-based diagnostics into the care of patients with cancer. There is an urgent need to assess the efficacy of therapy determined by molecular matching of patients with particular targeted therapies. WINTHER is a clinical trial that uses cutting edge genomic and transcriptomic assays to guide treatment decisions.

Urinary biomarkers for the detection of prostate cancer in patients with high-grade prostatic intraepithelial neoplasia.

Introduction: High-grade prostatic intraepithelial neoplasia (HGPIN) is a recognized precursor stage of PCa. Men who present HGPIN in a first prostate biopsy face years of active surveillance including repeat biopsies. This study aimed to identify non-invasive prognostic biomarkers that differentiate early on between indolent HGPIN cases and those that will transform into actual PCa.

Phase I Trial of the Pan-PI3K Inhibitor Pilaralisib (SAR245408/XL147) in Patients with Chronic Lymphocytic Leukemia (CLL) or Relapsed/Refractory Lymphoma.

Purpose: This phase I expansion-cohort study evaluated the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of the pan-PI3K inhibitor pilaralisib (SAR245408/XL147) in patients with chronic lymphocytic leukemia (CLL) or relapsed or refractory lymphoma.

Patients And Methods: Patients were treated with the maximum tolerated dose of pilaralisib previously determined in patients with solid tumors (600 mg capsules once daily). Adverse events (AE) and response were evaluated.

Assessing associations between the AURKA-HMMR-TPX2-TUBG1 functional module and breast cancer risk in BRCA1/2 mutation carriers.

While interplay between BRCA1 and AURKA-RHAMM-TPX2-TUBG1 regulates mammary epithelial polarization, common genetic variation in HMMR (gene product RHAMM) may be associated with risk of breast cancer in BRCA1 mutation carriers. Following on these observations, we further assessed the link between the AURKA-HMMR-TPX2-TUBG1 functional module and risk of breast cancer in BRCA1 or BRCA2 mutation carriers. Forty-one single nucleotide polymorphisms (SNPs) were genotyped in 15,252 BRCA1 and 8,211 BRCA2 mutation carriers and subsequently analyzed using a retrospective likelihood approach.

High within-day variability of fecal calprotectin levels in patients with active ulcerative colitis: what is the best timing for stool sampling?

Background: Fecal calprotectin (FC) is considered the best noninvasive way to assess disease activity in ulcerative colitis (UC). However, it is not known which is the more suitable moment for stool sampling in patients with increased stool frequency. The aims of this study were to assess the intraindividual variation of FC within day and to evaluate if the first bowel movement in the morning is the more suitable sample for FC measurement in patients with acute flares of UC.

Group therapy for adolescents with attention-deficit/hyperactivity disorder: a randomized controlled trial.

Objective: To determine the efficacy of group cognitive-behavioral therapy (CBT) on adolescents with attention-deficit/hyperactivity disorder (ADHD) who were in pharmacological treatment but still had persistent symptoms.

Method: We conducted a multicenter, randomized, rater-blinded, controlled trial between April 2012 and May 2014 in a cohort of 119 adolescents (15-21 years of age). Participants were randomly assigned to 12 manualized group CBT sessions (n = 45) or a waiting list control group (n = 44).

Background: Heat-shock protein 990 (HSP990) is a potent and selective synthetic small-molecule HSP90 inhibitor. The primary objectives of this phase I first-in-human study were to determine dose-limiting toxicities (DLTs), maximum-tolerated dose (MTD) and recommended phase II dose (RP2D). Secondary objectives included characterisation of the safety profile, pharmacokinetics (PKs) and pharmacodynamics (PDs).

Identification of six new susceptibility loci for invasive epithelial ovarian cancer.

Genome-wide association studies (GWAS) have identified 12 epithelial ovarian cancer (EOC) susceptibility alleles. The pattern of association at these loci is consistent in BRCA1 and BRCA2 mutation carriers who are at high risk of EOC. After imputation to 1000 Genomes Project data, we assessed associations of 11 million genetic variants with EOC risk from 15,437 cases unselected for family history and 30,845 controls and from 15,252 BRCA1 mutation carriers and 8,211 BRCA2 mutation carriers (3,096 with ovarian cancer), and we combined the results in a meta-analysis.

Pharmacokinetic, pharmacodynamic and biomarker evaluation of transforming growth factor-β receptor I kinase inhibitor, galunisertib, in phase 1 study in patients with advanced cancer.

Purpose Transforming growth factor-beta (TGF-β) signaling plays a key role in epithelial-mesenchymal transition (EMT) of tumors, including malignant glioma. Small molecule inhibitors (SMI) blocking TGF-β signaling reverse EMT and arrest tumor progression. Several SMIs were developed, but currently only LY2157299 monohydrate (galunisertib) was advanced to clinical investigation.

A five-gene hedgehog signature developed as a patient preselection tool for hedgehog inhibitor therapy in medulloblastoma.

Purpose: Distinct molecular subgroups of medulloblastoma, including hedgehog (Hh) pathway-activated disease, have been reported. We identified and clinically validated a five-gene Hh signature assay that can be used to preselect patients with Hh pathway-activated medulloblastoma.

Experimental Design: Gene characteristics of the Hh medulloblastoma subgroup were identified through published bioinformatic analyses.

Genetic barrier to resistance for dolutegravir.

Dolutegravir is a novel integrase strand-transfer inhibitor that displays potent in vitro activity and a remarkably different resistance profile. Its robust pharmacokinetic/pharmacodynamic properties - long plasma t1/2, high plasma inhibition quotient, and slow dissociation rate from the integrase complex - suggest it should present a high barrier to resistance development. This has been confirmed in pivotal phase III studies of initial therapy, with none out of 1,118 treated individuals selecting resistance-associated mutations at the integrase or reverse transcriptase.
