BACKGROUND: Patients under palliative care and in hospital-at-home services are frequently transferred to emergency departments. We set out to identify the reasons for these presentations to determine the proportion that might be avoidable. METHODS: We conducted a retrospective study by assessment of patient files. We studied admissions to four emergency departments in an area of France (Puy-de-Dôme) between September 2011 and August 2013. Reasons for transfer and diagnostic conclusion by emergency doctors were noted...

INTRODUCTION: Factor (F) XI supports both normal human hemostasis and pathological thrombosis. Activated FXI (FXIa) promotes thrombin generation by enzymatic activation of FXI, FIX, FX, and FV, and inactivation of alpha tissue factor pathway inhibitor (TFPIα), in vitro. Some of these reactions are now known to be enhanced by short-chain polyphosphates (SCP) derived from activated platelets. These SCPs act as a cofactor for the activation of FXI and FV by thrombin and FXIa, respectively...

Availability of magnesium is a matter of concern due to its role in many environmental and biological processes. Diffusive Gradients in Thin Films (DGT) devices can measure Mg availability in situ. This work shows that Mg accumulation in water largely increases when ionic strength (I) decreases. This phenomenon can be explained from (i) the increase of both the association equilibrium (K) and rate (ka,R) constants for the reaction between Mg cations and resin sites, and (ii) the growing contribution of the partitioning of Mg cations at the resin-gel interface, as I decreases...

INTRODUCTION: The effectiveness and safety of fingolimod in patients with relapsing-remitting multiple sclerosis (RRMS) have been proven in clinical trials. Yet, due to their limitations, it is important to know how it behaves under everyday clinical practice conditions. Hence, the aim of this study is to evaluate the effectiveness and safety of fingolimod after 12 months' usage in clinical practice in Galicia. PATIENTS AND METHODS: We conducted a retrospective, multi-centre study (n = 8) of patients with RRMS who were treated with one or more doses of fingolimod, 0...

INTRODUCTION: In COPD, the benefits of Pulmonary Rehabilitation (PR) tend to wane over time. Whether maintenance techniques may help sustain the benefits achieved after completion of the initial PR program remains controversial. OBJECTIVE: To determine whether a long-term (3-years) maintenance program after PR preserves the short-term effects on outcomes in patients with COPD. METHOD: This was a multi-center prospective randomized trial including 143 patients with moderate-severe COPD, with 3 years of PR maintenance following an 8-week outpatient PR program...

Liver ischemia-reperfusion injury (IRI) is an inherent feature of liver surgery and liver transplantation in which damage to a hypoxic organ (ischemia) is exacerbated following the return of oxygen delivery (reperfusion). IRI is a major cause of primary non-function after transplantation and may lead to graft rejection, regardless of immunological considerations. The immediate response involves the disruption of cellular mitochondrial oxidative phosphorylation and the accumulation of metabolic intermediates during the ischemic period, and oxidative stress during blood flow restoration...

Hepatic fibrosis is a scarring process that may progress to hepatic cirrhosis and even hepatic carcinoma if left untreated. Hepatic stellate cells (HSCs) play essential roles in the development of hepatic fibrosis. The tumor suppressor protein p53 is a transcription factor that is involved in cell proliferation, cell cycle regulation, apoptosis and DNA repair. Recombinant human adenovirus-p53 (Ad-p53) has been demonstrated to act as a promising antitumor gene therapy in various types of cancer. However, there is limited infomration regarding the therapeutic effect of Ad-p53 on the regression of hepatic fibrosis...

A total of 450 bacteria and yeast strains isolated from cloud waters sampled at the puy de Dôme station in France (1465 m) were screened for their ability to produce siderophores. To achieve this, a high-throughput method in 96-well plates was adapted from the CAS (chrome azurol S) method. Notably, 42% of the isolates were siderophore producers. This production was examined according to the phyla of the tested strains and the type of chelating functional groups (i.e., hydroxamate, catechol, and mixed type)...

The equilibrium between the ventricular and lumbar cerebrospinal fluid (CSF) compartments may be disturbed (in terms of flow and biochemistry) in patients with chronic hydrocephalus (CH). Using flow magnetic resonance imaging (MRI) and CSF assays, we sought to determine whether changes in CSF were associated with biochemical alterations. Nine elderly patients with CH underwent phase-contrast MRI. An index of CSF dynamics (Idyn) was defined as the product of the lumbar and ventricular CSF flows. During surgery, samples of CSF were collected from the lumbar and ventricular compartments and assayed for chloride, glucose and total protein...

Magnesium-based interference screws may be an alternative in anterior/posterior cruciate ligament reconstruction. The well-known osteoconductive effects of biodegradable magnesium alloys may be useful. It was the purpose of this study to evaluate the biomechanical properties of a magnesium based interference screw and compare it to a standard implant. A MgYREZr-alloy interference screw and a standard implant (Milagro®; De Puy Mitek, Raynham, MA, USA) were used for graft fixation. Specimens were placed into a tensile loading fixation of a servohydraulic testing machine...

Historical and traditional flood-irrigated (FI) schemes are progressively being upgraded by means of drip irrigation (DI) to tackle current water and demographic challenges. This modernization process is likely to foster several changes of environmental relevance at the system level. In this paper we assess the effects derived from DI uptake on soil health and structure in ancient FI systems through the case study of Ricote, SE Spain, first established in the 10-13th centuries CE. We approach the topic by means of physico-chemical analyses (pH, electrical conductivity, available P, carbon analyses, bulk density, soil water content and particle size distribution), Electrical Resistivity Measurements (ERT) and robust statistics...

Little is known about how patients influence health care providers' communication behavior, although this knowledge may contribute to the understanding of the reciprocal influence of patient and provider communication and the pathways between communication and health care outcomes. Therefore, the aim of this study was to explore patients' active communication behaviors and how this affects the immediate communication behavior of physicians. We coded 27 admission interviews from three German orthopedic rehabilitation centers with an adapted version of the Roter Interaction Analysis System...

Cerebrovascular pathologies expose patients to both ischemic and hemorrhagic risks. Given the progressive aging of populations, more and more patients will experience both types of events during their lifetime. The generalization of brain magnetic resonance imaging as a first-line imaging modality for evaluating patients with cerebrovascular diseases has led to the need to manage new types of imaging information about the cerebral tissue, such as the presence, location, and number of cerebral microhemorrhages (CMs)...

The endoplasmic reticulum (ER) is involved in calcium homeostasis, protein folding and lipid biosynthesis. Perturbations in its normal functions lead to a condition called endoplasmic reticulum stress (ERS). This can be triggered by many physiopathological conditions such as alcoholic steatohepatitis, insulin resistance or ischemia-reperfusion injury. The cell reacts to ERS by initiating a defensive process known as the unfolded protein response (UPR), which comprises cellular mechanisms for adaptation and the safeguarding of cell survival or, in cases of excessively severe stress, for the initiation of the cell death program...

Coagulation factor (F)XI has been described as a component of the early phase of the contact pathway of blood coagulation, acting downstream of factor XII. However, patients deficient in upstream members of the contact pathway, including FXII and prekallikrein, do not exhibit bleeding complications, while FXI-deficient patients sometimes experience mild bleeding, suggesting FXI plays a role in hemostasis independent of the contact pathway. Further complicating the picture, bleeding risk in FXI-deficient patients is difficult to predict because bleeding symptoms have not been found to correlate with FXI antigen levels or activity...

BACKGROUND: Erythropoietic protoporphyria (EPP) is a rare metabolic disorder, characterized by photosensitivity, caused by errors of the haem biosynthetic pathway. Avoidance of sun exposure is recommended; however, some patients suggested a paradoxical improvement of symptoms when they move to sunny areas. OBJECTIVES: In a national French study, we sought to investigate the influence of sun exposure on EPP symptoms. MATERIALS AND METHODS: We used a national transversal observational study by questionnaire...

Hepatic ischemia reperfusion injury (IRI) is an inevitable clinical problem for liver surgery. Polyethylene glycols (PEGs) are water soluble nontoxic polymers that have proven their effectiveness in various in vivo and in vitro models of tissue injury. The present study aims to investigate whether the intravenous administration of a high molecular weight PEG of 35 kDa (PEG 35) could be an effective strategy for rat liver preconditioning against IRI. PEG 35 was intravenously administered at 2 and 10 mg/kg to male Sprague Dawley rats...
