Rationale and study design for an Individualized PeriopeRative Open lung VEntilatory approach in Emergency Abdominal Laparotomy/scopy: study protocol for a prospective international randomized controlled trial.

Background: Postoperative pulmonary complications (PPC) are the most frequent postoperative complications, with an estimated prevalence in elective surgery ranging from 20% in observational cohort studies to 40% in randomized clinical trials. However, the prevalence of PPCs in patients undergoing emergency abdominal surgery is not well defined. Lung-protective ventilation aims to minimize ventilator-induced lung injury and reduce PPCs.

Switching and increasing prophylaxis regimen with a genetically recombinant fusion of coagulation factor IX and albumin in haemophilia B: a case report.

Purpose Of Review: We present a case of a boy diagnosed in 2007 with severe haemophilia B [factor IX (FIX) concentration < 1%] at age of 9 months. He was initially treated with recombinant FIX concentrates, but changes in regimens were frequent due to spontaneous hemarthros. In 2013, he entered a phase III trial (NCT01662531) and received rIX-FP, IDELVION at 50 IU/kg once a week.

MicroRNA cerebrospinal fluid profile during the early brain injury period as a biomarker in subarachnoid hemorrhage patients.

Introduction: Delayed cerebral ischemia (DCI) is a dreadful complication present in up to 30% of patients with spontaneous subarachnoid hemorrhage (SAH). Indeed, DCI is one of the main causes of long-term disability in SAH, yet its prediction and prevention are troublesome in poor-grade SAH cases. In this prospective study, we explored the potential role of micro ribonucleic acid (microRNA, abbreviated miRNAs)-small non-coding RNAs involved in clue gene regulation at the post-transcriptional level-as biomarkers of neurological outcomes in SAH patients.

Minimally Invasive Surgery for Spontaneous Intracerebral Hematoma. Real-Life Implementation Model and Economic Estimation.

Objective: Spontaneous intracerebral hemorrhage is characterized by high fatality outcomes, even under best medical treatment. Recently, minimally invasive surgical (MIS) evacuation of the hematoma has shown promising results and may soon be implemented in the clinical practice. Hereby, we intended to foresee the logistic requirements for an early hematoma evacuation protocol, as well as to evaluate in a real-life implementation model the cost-utility of the two main MIS techniques for hemorrhagic stroke (catheter evacuation plus thrombolysis and neuroendoscopic aspiration).

Implementing a Rapid Response System in a tertiary-care hospital. A cost-effectiveness study.

Purpose: The occurrence of adverse events (AE) in hospitalized patients substancially increases the risk of disability or death, having a major negative clinical and economic impact on public health. For early identification of patients at risk and to establish preventive measures, different healthcare systems have implemented rapid response systems (RRS). The aim of this study was to carry out a cost-effectiveness analysis of implementing a RRS in a tertiary-care hospital.

Preoperative soluble VCAM-1 contributes to predict late mortality after coronary artery surgery.

Background: Soluble vascular cell adhesion molecule-1 has been associated with long-term cardiovascular mortality in patients with stable coronary artery disease and to the development of new atrial fibrillation in subjects with cardiovascular risk factors but no evidence of cardiac disease.

Hypothesis: Preoperative soluble vascular cell adhesion molecule-1 predicts the risk of future all-cause death and cardiovascular death among patients submitted to elective coronary artery bypass surgery.

Methods: From a cohort of 312 patients who underwent elective coronary artery bypass surgery prospectively followed for a median of 6.

Characterization of the phone-calls made to a poison center related to household and cosmetics products exposition in pediatrics.

Introduction: Household cleaning products and cosmetics are necessary for daily life and widely used by the population. However, their use may not be risk-free, especially when they are not used or stored as recommended. It is important to characterize exposures, as this is useful for developing stra tegies to reduce morbidity, mortality, and health costs associated, especially in the child population.

Functional identification of a FKBP-like protein involved in the folding of overproduced secreted proteins.

Some bacterial peptidyl-prolyl isomerases (PPIases) are involved in secretory protein folding after the translocation step. has been used as a host for engineering extracellular overproduction of homologous and heterologous proteins in industrial applications. Although the mechanisms governing the major secretory pathway (Sec route) and the minor secretory pathway (Tat route) are reasonably well described, the function of proteins responsible for the extracellular secretory protein folding is not characterized as yet.

Dynamic metabolic modelling of overproduced protein secretion in Streptomyces lividans using adaptive DFBA.

Background: Streptomyces lividans is an appealing host for the production of proteins of biotechnological interest due to its relaxed exogenous DNA restriction system and its ability to secrete proteins directly to the medium through the major Sec or the minor Tat routes. Often, protein secretion displays non-uniform time-dependent patterns. Understanding the associated metabolic changes is a crucial step to engineer protein production.

Four thiol-oxidoreductases involved in the formation of disulphide bonds in the Streptomyces lividans TK21 secretory proteins.

Background: Bacterial secretory proteins often require the formation of disulphide bonds outside the cell to acquire an active conformation. Thiol-disulphide oxidoreductases are enzymes that catalyse the formation of disulphide bonds. The bacterium Streptomyces lividans is a well-known host for the efficient secretion of overproduced homologous and heterologous secretory proteins of industrial application.

Modelling the metabolism of protein secretion through the Tat route in Streptomyces lividans.

Background: Streptomyces lividans has demonstrated its value as an efficient host for protein production due to its ability to secrete functional proteins directly to the media. Secretory proteins that use the major Sec route need to be properly folded outside the cell, whereas secretory proteins using the Tat route appear outside the cell correctly folded. This feature makes the Tat system very attractive for the production of natural or engineered Tat secretory proteins.

The Cellular Mechanisms that Ensure an Efficient Secretion in Streptomyces.

Gram-positive soil bacteria included in the genus produce a large variety of secondary metabolites in addition to extracellular hydrolytic enzymes. From the industrial and commercial viewpoints, the strain has generated greater interest as a host bacterium for the overproduction of homologous and heterologous hydrolytic enzymes as an industrial application, which has considerably increased scientific interest in the characterization of secretion routes in this bacterium. This review will focus on the secretion machinery in .

Inhibition of mitochondrial fission prevents hypoxia-induced metabolic shift and cellular proliferation of pulmonary arterial smooth muscle cells.

Chronic hypoxia exacerbates proliferation of pulmonary arterial smooth muscle cells (PASMC), thereby reducing the lumen of pulmonary arteries. This leads to poor blood oxygenation and cardiac work overload, which are the basis of diseases such as pulmonary artery hypertension (PAH). Recent studies revealed an emerging role of mitochondria in PAH pathogenesis, as key regulators of cell survival and metabolism.

Increased C-reactive protein plasma levels are not involved in the onset of post-operative atrial fibrillation.

Background: Increased inflammation biomarkers plasma levels, including C-reactive protein (CRP), have been associated with the initiation and perpetuation of atrial fibrillation (AF). However, it is not known whether an increased CRP plasma level, without concomitant inflammation, is sufficient to induce AF. We investigated whether higher CRP plasma levels, determined by the presence of +219G>A CRP gene polymorphism, is associated with an increased risk of post-operative AF.

Transforming growth factor-beta and Forkhead box O transcription factors as cardiac fibroblast regulators.

Fibroblasts play several homeostatic roles, including electrical coupling, paracrine signaling and tissue repair after injury. Fibroblasts have low secretory activity. However, in response to injury, they differentiate to myofibroblasts.

Novel Therapies Targeting Cardioprotection and Regeneration.

Cardiovascular disease is the leading cause of death worldwide. The heart is susceptible to pathologies that impact the myocardium directly, such as myocardial infarction and consequent heart failure, as well as conditions with indirect cardiac effects, such as cancer treatment-related cardiotoxicity. As the contractile cells of the heart, cardiomyocytes are essential for normal cardiac function.

The Three Streptomyces lividans HtrA-Like Proteases Involved in the Secretion Stress Response Act in a Cooperative Manner.

Overproduction of Sec-proteins in S. lividans accumulates misfolded proteins outside of the cytoplasmic membrane where the accumulated proteins interfere with the correct functioning of the secretion machinery and with the correct cell functionality, triggering the expression in S. lividans of a CssRS two-component system which regulates the degradation of the accumulated protein, the so-called secretion stress response.
