PURPOSE: Patients, family members, and physicians participate in cancer care, but their perspectives about what is helpful during cancer treatment have rarely been compared. The aim of this study was to compare these three perspectives. METHODS: Multicenter qualitative study (with previously published protocol) based on 90 semi-structured interviews. Participants (purposively selected until data saturation) came from three different subsamples: (i) patients with cancer (n=30), (ii) their relatives (n=30), and (iii) their referring physicians (n=10, interviewed more than once)...

Semicarbazide-sensitive amine oxidase (SSAO), identical to primary amine oxidase or vascular adhesion protein-1, is a membrane enzyme that generates hydrogen peroxide. SSAO is highly expressed at the adipocyte surface, and its plasma levels increase with type 2 diabetes. Since visceral adipose tissue (AT) is more tightly associated with obesity complications than subcutaneous (SC) abdominal fat, we compared SSAO activity in plasma and 4 distinct AT locations in 48 severely obese women (body mass index (BMI), averaging 54 ± 11 kg/m(2)), with or without a dysmetabolic profile...

BACKGROUND: There is little evidence regarding the efficacy and safety of bioresorbable scaffolds (BRS) for the percutaneous treatment of chronic total occlusions. METHODS AND RESULTS: We performed a multicenter registry of consecutive chronic total occlusion patients treated with BRS (Absorb; Abbott Vascular) and second-generation drug-eluting stents (DES) at 5 institutions. Long-term target-vessel failure (a composite of cardiac death, target-vessel myocardial infarction, and ischemia-driven target-lesion revascularization) was the primary end point...

Media reporting on suicide may have harmful and/or protective effects on deaths by suicide, depending on the nature of the coverage. Canada's first forum on this important issue was held in Toronto on November 6, 2015. Participating in the forum were public health policy-makers, mental health and suicide prevention experts and senior media representatives. This commentary summarizes the content of the forum and highlights the need for ongoing collaboration between suicide prevention experts and media professionals aimed at safe and respectful reporting that maintains the public's need to be informed...

The ubiquitin-proteasome pathway is involved in the pathogenesis of several neurogenetic diseases. We describe a Mauritanian patient harboring a homozygous deletion restricted to two contiguous genes HERC2 and OCA2 and presenting with severe developmental abnormalities. The deletion causes the complete loss of HERC2 protein function, an E3-ubiquitin ligase. HERC2 is known to target XPA and BRCA1 for degradation and a mechanism whereby it is involved in DNA repair and cell cycle regulation. We showed that loss of HERC2 function leads to the accumulation of XPA and BRCA1 in the patient's fibroblasts and generates decreased sensitivity to apoptosis and increased level of DNA repair...

To save energy, the European directives from the Eco-design of Energy Using Products (2005/32/CE) has recommended the replacement of incandescent lamps by more economic devices such as Light Emitting Diodes (LEDs). However, the emission spectrum of these devices is enriched in blue radiations, known to be potentially dangerous to the retina. Recent studies showed that light exposure contribute to the onset of early stages of Age related macular degeneration (AMD). Here, we investigate, in albinos and pigmented rats, the effects of different exposure protocols...

Stress-related pathophysiology drives comorbid trajectories that elude precise prediction. Allostatic load algorithms that quantify biological "wear and tear" represent a comprehensive approach to detect multisystemic disease processes of the mind and body. However, the multiple morbidities directly or indirectly related to stress physiology remain enigmatic. Our aim in this article is to propose that biological comorbidities represent discrete pathophysiological processes captured by measuring allostatic load...

The biodiversity-productivity relationship (BPR) is foundational to our understanding of the global extinction crisis and its impacts on ecosystem functioning. Understanding BPR is critical for the accurate valuation and effective conservation of biodiversity. Using ground-sourced data from 777,126 permanent plots, spanning 44 countries and most terrestrial biomes, we reveal a globally consistent positive concave-down BPR, showing that continued biodiversity loss would result in an accelerating decline in forest productivity worldwide...

Docetaxel, cisplatin, and 5-fluorouracil (DCF) significantly improved overall survival in metastatic gastroesophageal adenocarcinoma (GEA). The aim of this study was to assess efficacy of DCF regimen as perioperative chemotherapy compared with surgery alone in patients with resectable GEA. We identified 789 patients who underwent surgery alone and 62 patients who received at least one cycle of DCF regimen consisting of docetaxel (75 mg/m(2) on day 1), cisplatin (75 mg/m(2) on day 1), and 5-fluorouracil (750 mg/m(2) /day on continuous perfusion on days 1 to 5), every 3 weeks...

The advent of next-generation sequencing (NGS) in 2010 has transformed medicine, particularly the growing field of inborn errors of immunity. NGS has facilitated the discovery of novel disease-causing genes and the genetic diagnosis of patients with monogenic inborn errors of immunity. Whole-exome sequencing (WES) is presently the most cost-effective approach for research and diagnostics, although whole-genome sequencing offers several advantages. The scientific or diagnostic challenge consists in selecting 1 or 2 candidate variants among thousands of NGS calls...

INTRODUCTION: "Café au lait" spots (CLS) are pigmented skin lesions principally located at the trunk and the limbs. Histologically, CLSs consist in an excessive pigmentation of the epidermis, with no risk of malignant transformation. The "kissing" nevus is a rare pigmented congenital nevus affecting both lower and upper eyelids in a mirror layout. As other nevi, it presents a theoretical risk of malignant transformation. These two pigmented lesions are responsible for aesthetic discomfort when affecting the face...

BACKGROUND: The yield obtained from next generation sequencers has increased almost exponentially in recent years, making sample multiplexing common practice. While barcodes (known sequences of fixed length) primarily encode the sample identity of sequenced DNA fragments, barcodes made of random sequences (Unique Molecular Identifier or UMIs) are often used to distinguish between PCR duplicates and transcript abundance in, for example, single-cell RNA sequencing (scRNA-seq). In paired-end sequencing, different barcodes can be inserted at each fragment end to either increase the number of multiplexed samples in the library or to use one of the barcodes as UMI...

PURPOSE: The aim of this study was to assess the kinematics of arthritic knees prior to TKA. The hypothesis was that the arthritic knee follows distinct patterns with regard to deformity in coronal plane as it flexes from extended position. METHOD: Data from 585 consecutive arthritic knees that had undergone TKA using two non-image-based navigation systems were included in the study. Coronal plane alignment given by the femoro-tibial mechanical angle (FTMA) was recorded in extension, 30°, 60°, 90° and maximum flexion prior to making any bony cuts or ligamentous releases...

Successful treatment of a Candida infection relies on 1) an accurate identification of the pathogenic fungus and 2) on its susceptibility to antifungal drugs. In the present study we investigated the level of correlation between phylogenetical evolution and susceptibility of pathogenic Candida spp. to antifungal drugs. For this, we compared a phylogenetic tree, assembled with the concatenated sequences (2475-bp) of the ATP2, TEF1, and TUF1 genes from 20 representative Candida species, with published minimal inhibitory concentrations (MIC) of the four principal antifungal drug classes commonly used in the treatment of candidiasis: polyenes, triazoles, nucleoside analogues, and echinocandins...

Functional genomic analysis of gene expression in mice allowed us to identify a quantitative trait locus (QTL) linked in trans to the expression of 190 gene transcripts and in cis to the expression of only two genes, one of which was Ypel5. Most of the trans-expression QTL genes were interferon-stimulated genes (ISGs), and their expression in mouse macrophage cell lines was stimulated in an IFNB1-dependent manner by Ypel5 silencing. In human HEK293T cells, YPEL5 silencing enhanced the induction of IFNB1 by pattern recognition receptors and phosphorylation of TBK1/IKBKE kinases, whereas co-immunoprecipitation experiments revealed that YPEL5 interacted physically with IKBKE...

BACKGROUND: Chronic granulomatous disease (CGD) is primary immunodeficiency caused by defective production of reactive oxygen species in phagocytic cells that results in life-threatening infections and severe inflammatory manifestations. The treatment of inflammatory manifestations remains challenging, as it can be associated with an increased risk of infections. Previous studies have shown that CGD phagocytes display a defect in autophagy and a reactive oxygen species-independent activation of the inflammasome...
