EYE LENS RADIATION EXPOSURE OF WORKERS DURING MEDICAL INTERVENTIONAL PROCEDURES AND SURGERY.

To evaluates the eye-lens radiation exposure of workers during medical interventional procedures and surgery in a military hospital as well as of the equine veterinarians. The measures represent the exposure in a normal workload schedule of ninety randomly selected workers over a 3-month period, extrapolated to 1 year. The eye-lens dosemeters were placed near the eye closest to the radiation source (Carinou, E.

Re-emergence of Corynebacterium diphtheriae.

Background: Diphtheria is re-emerging in Europe. A total of 36 cases were reported in Europe in 2015 versus 53 cases between 2000 and 2009.

Patients: We report two cases of Corynebacterium diphtheriae infection in a French hospital in 2016: a cutaneous infection with negative toxin testing in a French traveller, and a respiratory diphtheria carriage with positive toxin testing in an Afghan refugee diagnosed with pulmonary tuberculosis.

Sex differences in mandibular repositioning device therapy effectiveness in patients with obstructive sleep apnea syndrome.

Purpose: Mandibular repositioning devices (MRDs) are an effective treatment option for obstructive sleep apnea syndrome (OSAS), particularly in patients who refuse or cannot tolerate continuous positive airway pressure (CPAP). However, sex differences in the response to therapy and predictors of response are not clearly defined. This analysis of data from the long-term prospective ORCADES trial compared MRD efficacy in men and women with OSAS.

Prevalence and risk factors for acute kidney injury among trauma patients: a multicenter cohort study.

Background: Organ failure, including acute kidney injury (AKI), is the third leading cause of death after bleeding and brain injury in trauma patients. We sought to assess the prevalence, the risk factors and the impact of AKI on outcome after trauma.

Methods: We performed a retrospective analysis of prospectively collected data from a multicenter trauma registry.

Human diaphragm atrophy in amyotrophic lateral sclerosis is not predicted by routine respiratory measures.

Amyotrophic lateral sclerosis (ALS) patients show progressive respiratory muscle weakness leading to death from respiratory failure. However, there are no data on diaphragm histological changes in ALS patients and how they correlate with routine respiratory measurements.We collected 39 diaphragm biopsies concomitantly with laparoscopic insertion of intradiaphragmatic electrodes during a randomised controlled trial evaluating early diaphragm pacing in ALS (https://clinicaltrials.

Etiology and prognosis of acute respiratory failure in patients with primary malignant brain tumors admitted to the intensive care unit.

Purpose: Acute respiratory failure (ARF) is common and potentially fatal in patients with primary malignant brain tumors (PMBT). However, few data are available regarding its precipitating factors and prognosis. We sought to: (1) compare the causes of ARF and the outcome between patients with PMBT and patients with other peripheral solid tumors (PST), (2) identify the factors influencing ICU survival in PMBT patients.

Diaphragm-protective mechanical ventilation.

Purpose Of Review: Diaphragm dysfunction is common in mechanically ventilated patients and predisposes them to prolonged ventilator dependence and poor clinical outcomes. Mechanical ventilation is a major cause of diaphragm dysfunction in these patients, raising the possibility that diaphragm dysfunction might be prevented if mechanical ventilation can be optimized to avoid diaphragm injury - a concept referred to as diaphragm-protective ventilation. This review surveys the evidence supporting the concept of diaphragm-protective ventilation and introduces potential routes and challenges to pursuing this strategy.

Detection and management of dyspnea in mechanically ventilated patients.

Purpose Of Review: In ICU patients, dyspnea is one of the most prominent and distressing symptom. We sought to summarize current data on the prevalence and prognostic influence of dyspnea in the ICU setting and to provide concise and useful information for dyspnea detection and management.

Recent Findings: As opposed to pain, dyspnea has been a neglected symptom with regard to detection and management.

Acute respiratory failure in immunocompromised adults.

Acute respiratory failure occurs in up to half of patients with haematological malignancies and 15% of those with solid tumours or solid organ transplantation. Mortality remains high. Factors associated with mortality include a need for invasive mechanical ventilation, organ dysfunction, older age, frailty or poor performance status, delayed intensive care unit admission, and acute respiratory failure due to an invasive fungal infection or unknown cause.

A case of unexplained dyspnoea: when lung function testing matters!

http://ow.ly/ChbX30m91bt.

The multidimensional nature of dyspnoea in amyotrophic lateral sclerosis patients with chronic respiratory failure: Air hunger, anxiety and fear.

Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder leading to chronic respiratory failure. Few studies have investigated ALS-related dyspnoea, and none have characterised the emotional distress it inflicts. We hypothesised that ALS-related dyspnoea has a strong affective component that relates to quality of life.

Survival of amyotrophic lateral sclerosis patients after admission to the intensive care unit for acute respiratory failure: an observational cohort study.

Purpose: Amyotrophic lateral sclerosis (ALS) entails a risk of acute respiratory failure (ARF). The decision to admit such patients to the intensive care unit (ICU) is difficult given the inexorable prognosis of ALS. To fuel this discussion, this study describes the ICU and post-ICU survival of ALS-related ARF.

Neuroergonomic and psychometric evaluation of full-face crew oxygen masks respiratory tolerance: a proof-of-concept study.

Introduction: Preventing in-flight hypoxia in pilots is typically achieved by wearing oxygen masks. These masks must be as comfortable as possible to allow prolonged and repeated use. The consequences of mask-induced facial contact pressure have been extensively studied, but little is known about mask-induced breathing discomfort.

Effects of L-Carnitine on Mineral Metabolism in the Multicentre, Randomized, Double Blind, Placebo-Controlled CARNIDIAL Trial.

Background: The use of L-carnitine has been proposed in haemodialysis (HD) when deficiency is present to improve anaemia resistant to erythropoietin stimulating agent, intradialytic hypotension or cardiac failure. We tested the effects of L-carnitine supplementation on parameters of chronic kidney disease-mineral bone disorder.

Methods: CARNIDIAL was a randomized, double-blinded trial having included 92 incident HD subjects for a 1-year period to receive L-carnitine versus placebo.

Slower Is Higher: Threshold Modulation of Cortical Activity in Voluntary Control of Breathing Initiation.

Speech or programmed sentences must often be interrupted in order to listen to and interact with interlocutors. Among many processes that produce such complex acts, the brain must precisely adjust breathing to produce adequate phonation. The mechanism of these adjustments is multifactorial and still poorly understood.

[Drug-induced interstitial pneumonitis due to avelumab: A case report].

Introduction: The anti programmed death-1 (PD-1) and the programmed death ligand 1 (PD-L1) antibodies are used as immunotherapies in the treatment of many solid tumours. Cases of interstitial pneumonitis induced by anti PD-1 have been widely described, but there are fewer data with anti PD-L1. Avelumab is a new immunotherapy of the anti PD-L1 class.

Conscious processing of auditory regularities induces a pupil dilation.

Pupil dilation has been reliably identified as a physiological marker of consciously reportable mental effort. This classical finding raises the question of whether or not pupil dilation could be a specific somatic signature of conscious processing. In order to explore this possibility, we engaged healthy volunteers in the 'local global' auditory paradigm we previously designed to disentangle conscious from non-conscious processing of novelty.

Parietal Involvement in the Semantic Variant of Primary Progressive Aphasia with Alzheimer's Disease Cerebrospinal Fluid Profile.

Semantic variant of primary progressive aphasia (svPPA) is typically associated with non-Alzheimer's disease (AD) pathology. However, some anatomopathological studies have found AD lesions in those patients. We compared brain perfusion SPECT of 18 svPPA patients with cerebrospinal fluid (CSF) biomarkers indicative of non-AD pathology (svPPA-nonAD) and three svPPA patients with CSF biomarkers indicative of underlying AD (svPPA-AD).

Obstructive sleep apnea and chronic kidney disease.

Purpose Of Review: Obstructive sleep apnea (OSA) is highly prevalent in patients with chronic kidney disease (CKD). The relationship between OSA and CKD is likely to be bi-directional. On one hand, the presence of OSA leads to intermittent hypoxia, sympathetic nervous system activity, and hypertension, all of which may have deleterious effects on kidney function.

Combined diffusion tensor imaging and magnetic resonance spectroscopy to predict neurological outcome before transjugular intrahepatic portosystemic shunt.

Background: Hepatic encephalopathy (HE) may occur after transjugular intrahepatic portosystemic shunt (TIPSS) placement. Multimodal magnetic resonance imaging (MRI), combining anatomical sequences, diffusion tensor imaging (DTI) and H magnetic resonance spectroscopy, is modified in cirrhotic patients.

Aims: To describe multimodal MRI images before TIPSS, to assess if TIPSS induces changes in multimodal MRI, and to find predictors of HE after TIPSS in patients with cirrhosis.
