Envenoming and deaths resulting from snakebites are a particularly important public health problem in rural tropical areas of Africa, Asia, Latin America and New Guinea. In 2015 The Lancet highlighted snake-bite envenoming as a neglected tropical disease and urged the world to increase antivenom production. In Brazil around 20,000 snakebites occur per year affecting mostly agricultural workers and children, of which 1% are caused by coral snakes (Micrurus sp). Although human envenoming by coral snakes are relatively rare due to their semifossorial habits and non-aggressive behavior, they are always considered severe due to the neurotoxic, myotoxic, hemorrhagic and cardiovascular actions of their venom, which is highly toxic when compared to the venom of other Brazilian venomous snakes as Bothrops sp (pit vipers), Crotalus sp (rattlesnakes) and Lachesis sp (bushmasters)...

INTRODUCTION: Most infants born before 30 weeks gestational age (GA) develop respiratory distress syndrome soon after birth. Methods of surfactant administration that avoid ventilation have been recently introduced. The aim of this study was to evaluate the impact of implementing a new procedure of less invasive surfactant administration (LISA) and determine whether it is associated with an improvement in respiratory outcome. METHODS: This single center cohort quality improvement study analyzed preterm infants born before 30 weeks GA between May 2010 and April 2016...

The central functions fulfilled by mitochondria as both energy generators essential for tissue homeostasis and gateways to programmed apoptotic and necrotic cell death mandate tight control over the quality and quantity of these ubiquitous endosymbiotic organelles. Mitophagy, the targeted engulfment and destruction of mitochondria by the cellular autophagy apparatus, has conventionally been considered as the mechanism primarily responsible for mitochondrial quality control. However, our understanding of how, why, and under what specific conditions mitophagy is activated has grown tremendously over the past decade...

BACKGROUND AND AIM: Unplanned extubation (UE) in Intensive Care Units (ICU) is an indicator of quality and safety of care. UEs are classified in: accidental extubations, if involuntarily caused during nursing care or medical procedures; self-extubation, if determined by the patient him/herself.  In scientific literature, the cumulative incidence of UEs varies from 0.3% to 35.8%. The aim of this study is to explore the incidence of UEs in an Italian university general ICU adopting a well-established protocol of tracheal tube nursing management and fixation...

Nonviral gene transfection overcomes some of the disadvantages of viral vectors, such as undesired immune responses, safety concerns, issues relating to bulk production, payload capacity, and quality control, but generally have low transfection efficiency. Here we describe the effects of a modified form of photodynamic therapy (PDT), i.e., photochemical internalization (PCI) to: (1) greatly increase nonviral cytosine deaminase gene (CD) transfection into tumor cells, significantly increasing the conversion of 5-fluorocytosine (5-FC) to 5-fluorouracil (5-FU), and (2) enhance the toxic efficacy of the locally produced 5-FU to induce cell death on both transfected and non-transfected bystander cells...

Growing amount of evidence in the last two decades highlight that macroautophagy (generally referred to as autophagy) is not only indispensable for survival in yeast but also equally important to maintain cellular quality control in higher eukaryotes as well. Importantly, dysfunctional autophagy has been explicitly shown to be involved in various physiological and pathological conditions such as cell death, cancer, neurodegenerative, and other diseases. Therefore, modulation and regulation of the autophagy pathway has emerged as an alternative strategy for the treatment of various disease conditions in the recent years...

Cystic fibrosis (CF) is a progressive, chronic and debilitating genetic disease caused by mutations in the CF Transmembrane-Conductance Regulator ( CFTR ) gene. Unrelenting airway disease begins in infancy and produces a steady deterioration in quality of life, ultimately leading to premature death. While life expectancy has improved, current treatments for CF are neither preventive nor curative. Since the discovery of CFTR the vision of correcting the underlying genetic defect - not just treating the symptoms - has been developed to where it is poised to become a transformative technology...

Although in situ internal mammary artery (is-IMA) grafting remains the most frequent conduit in coronary artery bypass grafting (CABG), circumstances may necessitate free grafting of the IMA (f-IMA), though differences in outcomes have not been fully characterized. The purpose of this study was to compare clinical and angiographic outcomes of is-IMA versus f-IMA coronary bypass grafts in patients who underwent elective CABG surgery. In 1,829 patients in the angiographic cohort of PREVENT IV, 1,572 (85.9%) had at least 1 IMA graft; of these, 34 (2...

BACKGROUND: About one quarter of children affected with cancer die. For children and their families, the end-of-life period is highly distressing. AIM: This study focused on how end-of-life care in pediatric cancer patients changed over a period of 10 years and if changes in pediatric palliative care structures were associated with quality of care. DESIGN: Over a 10-year period, all pediatric oncology departments in one German federal state were invited to participate in a repeated cross-sectional cohort study at three time-points (2005, 2010, 2015)...

This study investigated the interactions between cumulus cells (CCs) and oocytes and programmed cell death in bovine cumulus-oocyte complexes (COCs) with different morphological characteristics. DNA fragmentation was assessed in CCs at 0 and 24 h of maturation, as well as parthenogenetic developmental competence on the 9th day post-activation, blastocyst quality and BCL-2 and BAX transcript levels in matured CCs. Most immature oocytes in the COC-A group (full cumulus and several compact layers) were in the initial germinal vesicle (iGV) stage, exhibiting minimal or no DNA damage...

BACKGROUND: Approximately one quarter of all deaths globally are attributed to living or working in an unhealthy environment, with household and ambient air pollution, along with exposures to ultraviolet radiation and chemicals amongst the leading causes. At present there are no international standards for assessing the risks of these environmental hazards. The use of heterogeneous methods to identify health risks from environmental hazards may reduce the level of confidence the public has in the conclusions that are made...

BACKGROUND: There is evidence that implantable cardioverter-defibrillator (ICD) for primary prevention in people with an ischaemic cardiomyopathy improves survival rate. The evidence supporting this intervention in people with non-ischaemic cardiomyopathy is not as definitive, with the recently published DANISH trial finding no improvement in survival rate. A systematic review of all eligible studies was needed to evaluate the benefits and harms of using ICDs for primary prevention in people with non-ischaemic cardiomyopathy...

REVIEW
Reinhard Strametz, Martin N Bergold, Tobias Weberschock
BACKGROUND: Percutaneous dilatational tracheostomy (PDT) is one of the most common bedside surgical procedures performed in critically ill adults, on intensive care units (ICUs), who require long-term ventilation. PDT is associated with relevant life-threatening complications: Cuff rupture or accidental extubation may lead to hypoxia, aspiration or loss of airway. Puncture of the oesophagus, or creating a false passage during dilatation or replacement of the tracheostomy tube, can lead to pneumothorax or emphysema...

Background: Advance care planning (ACP) is a crucial element of palliative care. It improves the quality of end-of-life care and reduces aggressive and needless life-prolonging medical interventions. However, little is known about its application in daily practice. This study aims to examine the application of ACP for patients with cancer in general practice. Methods: We performed a retrospective cohort study in 11 general practices in the Netherlands. Electronic patient records (EPRs) of deceased patients with colorectal or lung cancer were analysed...

Estimation of maternal mortality ratio (MMR) in humanitarian settings ('settings of conflict, displacement and natural disaster') is challenging, particularly where communities have dissolved and geographical areas are inaccessible. During humanitarian events, the reproduction of maternal mortality figures by the media is common, and are often based on inaccurate reports. In light of such uncertainties and challenges, the aim of this article was to review and appraise the methodology and data collection tools used to measure MMR in humanitarian settings...
