Mitochondria are sentinel organelles that are impacted by various forms of cellular stress, including viral infections. While signaling events associated with mitochondria, including those activated by pathogen associated molecular patterns (PAMPs), are widely studied, alterations in mitochondrial distribution and changes in mitochondrial dynamics are also beginning to be associated with cellular insult. Cells of neuronal origin have been demonstrated to display remarkable alterations in several instances, including neurodegenerative disorders...

Dinophysis acuminata and Dinophysis acuta are recurrent species off NW Iberia but their outbreaks occur under different conditions. A decade (2004-2013) of weekly data for each species at two sentinel stations located at the entrance of Rias de Aveiro-AV (NW Portugal, 40°38.6'N) and Pontevedra-PO (Galicia, Spain, 42°21.5'N), were used to investigate the regional synchronism and mesoscale differences related to species detection, bloom (>200cellsL(-1)) initiation and development. Results highlight the high interannual variability of bloom events and summarize the associated meteorological/oceanographic conditions...

OBJECTIVE: Electrical injuries in swimming pools are an important pediatric public health concern. We sought to (1) improve our understanding of the clinical presentation and outcomes following and (2) describe the epidemiology of swimming pool electrical injuries in the United States. METHODS: We reviewed 4 cases of pediatric (<18 y old) electrical injury from a single, urban level 1 pediatric trauma center. We also queried the National Electronic Injury Surveillance System (NEISS) for emergency department visits due to electrical injury associated with swimming pools, occurring between 1991 and 2013...

My arguments regarding postmastectomy radiotherapy (PMRT) for this case are based on the following 4 reasons: (1) high rate of local recurrence in the no PMRT group in the Early Breast Cancer Trialists' Collaborative Group meta-analysis on which the present guideline is based, (2) stage migration by sentinel node biopsy, (3) possible adverse events of radiotherapy, and (4) problems on extrapolation of data from western countries.

INTRODUCTION: In 2010, WHO recommended a new first-line treatment for visceral leishmaniasis (VL) in Eastern Africa. The new treatment, a combination of intravenous (IV) or intramuscular (IM) sodium stibogluconate (SSG) and IM paromomycin (PM) was an improvement over SSG monotherapy, the previous first-line VL treatment in the region. To monitor the new treatment's safety and effectiveness in routine clinical practice a pharmacovigilance (PV) programme was developed. METHODS: A prospective PV cohort was developed...

BACKGROUND: Axillary surgery is an established part of the management of primary breast cancer. It provides staging information to guide adjuvant therapy and potentially local control of axillary disease. Several alternative approaches to axillary surgery are available, most of which aim to spare a proportion of women the morbidity of complete axillary dissection. OBJECTIVES: To assess the benefits and harms of alternative approaches to axillary surgery (including omitting such surgery altogether) in terms of overall survival; local, regional and distant recurrences; and adverse events...

As the world continues to react and respond inefficiently to emerging infectious diseases, such as Middle Eastern Respiratory Syndrome and the Ebola and Zika viruses, a growing transdisciplinary community has called for a more proactive and holistic approach to prevention and preparedness - One Health. Such an approach presents important opportunities to reduce the impact of disease emergence events and also to mitigate future emergence through improved cross-sectoral coordination. In an attempt to provide proof of concept of the utility of the One Health approach, the US Agency for International Development's PREDICT project consortium designed and implemented a targeted, risk-based surveillance strategy based not on humans as sentinels of disease but on detecting viruses early, at their source, where intervention strategies can be implemented before there is opportunity for spillover and spread in people or food animals...

BACKGROUND: Both frequency and intensity of flood events are expected to increase as a result of global climate change in the upcoming decades, potentially resulting in increased re-suspension of sediments in fluvial systems. Contamination of these re-suspended sediments with legacy contaminants, including dioxins and dioxin-like compounds (DLCs), as well as polycyclic aromatic hydrocarbons (PAHs) is of great ecotoxicological concern. DLCs, and to some extent also PAHs, exhibit their toxicity through activation of the aryl hydrocarbon receptor (AhR)...

This report sought to critically examine proposals, potentials, and challenges of environmental health observatories with an emphasis on climate change processes. A critical review of existing environmental health observatories was performed, examining their purposes, potential audiences, and technological platforms. The implementation of the Brazilian Climate and Health Observatory (C&HO) is described, and two stages are defined: (i) the requirement analysis and negotiation stage that identified the national and regional institutional players and their roles as data producers/users; and (ii) thematic health-related workshops that reviewed water-related diseases, vector-borne diseases, extreme climate events, and health problems derived from forest fires...

The desire to use sentinel species as early warning indicators of impending climate change effects on entire ecosystems is attractive, but we need to verify that such approaches have sound biological foundations. A recent large-scale warming event in the North Pacific Ocean of unprecedented magnitude and duration allowed us to evaluate the sentinel status of giant kelp, a coastal foundation species that thrives in cold, nutrient-rich waters and is considered sensitive to warming. Here, we show that giant kelp and the majority of species that associate with it did not presage ecosystem effects of extreme warming off southern California despite giant kelp's expected vulnerability...

Nurse staffing, increased workload and unstable nursing unit environments are linked to negative patient outcomes including falls and medication errors on medical/surgical units. Considering this evidence, the aim of our study was to overview midwives' workload and work setting. We created a questionnaire and performed an online survey. We obtained information about the type and level of hospital, workload, the use of standardised procedures, reporting of sentinel and 'near-miss' events. We reported a severe understaffing in midwives' work settings and important underuse of standard protocols according to the international guidelines, especially in the South of Italy...

PURPOSE OF REVIEW: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a life-threatening syndrome defined by exercise-induced or emotion-induced ventricular arrhythmias, typically caused by gain-of-function mutations in RYR2-encoded ryanodine receptor-2 (RyR2). This review will discuss recent advances and ongoing challenges in devising genotype-specific CPVT therapies. RECENT FINDINGS: CPVT patients were once universally thought to be at high risk of sudden death; however, as more cases emerge, CPVT is being re-defined as a complex syndrome of variable expressivity...

The recently reported significant prolongation of overall survival with ipilimumab as adjuvant in high-risk stage III melanoma patients represents an important event in the adjuvant treatment landscape. The European Organisation for Research and Treatment of Cancer 18071 trial demonstrated a 28% reduction in risk of death in patients treated with ipilimumab at 10 mg/kg (hazard ratio for death, 0.72; 95.1% CI, 0.58-0.88; P = 0.001) compared with placebo. All end-points-recurrence-free survival (RFS), distant-metastasis-free survival (DMFS) and overall survival (OS)-showed similar benefits...

Vascular Endotelial Growth Factors C and D (VEGF-C and VEGF-D) are crucial regulators of lymphangiogenesis, a main event in the metastatic spread of breast cancer tumors. Although inhibition of lymphangiogenic gene expression might be a useful therapeutic strategy to restrict the progression of cancer, the factors involved in the transcriptional repression of these genes are still unknown. We have previously shown that Nuclear Receptor Corepressor 1 (NCoR) and the thyroid hormone receptor β1 (TRβ) inhibit tumor invasion...
