Circulating angiotensin II (AngII) is vital for arterial pressure elevation following intermittent hypoxia in rats, but its importance in the induction of sympathetic changes is unclear. We tested the contribution of the RAS to the effects of acute intermittent hypoxia (AIH) in anaesthetized ventilated adult rats. AIH caused a 33.7 ± 2.9% increase in sympathetic nerve activity (SNA), and a one-fold increase in sympathetic peripheral chemoreflex sensitivity and central sympathetic-respiratory coupling. The sympathetic effects of AIH were prevented by blocking angiotensin type 1 receptors with systemic losartan and intermittent systemic injections of AngII (Int...

BACKGROUND: Little is known about the prevalence of latent tuberculosis infection (LTBI) among coal workers' pneumoconiosis (CWP) patients. To estimate the prevalence of LTBI and identify its associated risk factors among CWP patients. METHODS: A cross-sectional study was conducted to assess the prevalence of LTBI. Participants were screened for active TB or a history of TB by X-ray and those that underwent QuantiFERON-TB Gold In-Tube (QFT) test. A standardized questionnaire was completed and risk factors were assessed for acquiring TB...

In thoracic surgery, the introduction of video-assisted thoracoscopic techniques has allowed the development of fast-track protocols, with shorter hospital lengths of stay and improved outcomes. The perioperative management needs to be optimized accordingly, with the goal of reducing postoperative complications and speeding recovery times. Premedication performed in the operative room should be wisely administered because often linked to late discharge from the post-anesthesia care unit (PACU). Inhalatory anesthesia, when possible, should be preferred based on protective effects on postoperative lung inflammation...

AIMS: Avoiding propofol in patients with Brugada syndrome has been suggested because of the theoretical risk of provoking ventricular arrhythmias, although propofol may be selected for conscious sedation during electrophysiological procedures in catheterization laboratories. This study aimed to document peri-procedural electrocardiographic changes and adverse events in patients with Brugada syndrome undergoing implantable cardioverter defibrillator (ICD) implantation using propofol sedation...

Little is known about the alcohol habits of people with advanced lung disease. Following lung transplantation patients are asked to abstain from or minimize alcohol use. The aim of this investigation is to assess alcohol use in a cohort of patients with advanced lung disease undergoing evaluation for lung transplant. This is a prospective observational investigation comparing patient self-report of alcohol use with their responses on the Alcohol Use Disorder and Identification Test, and alcohol biomarkers collected at the time of transplant...

AIM: We evaluated the impact that having a child with sleep-disordered breathing had on their parents, including their own sleep quality. METHODS: Questionnaires were completed by 96 parents of 86 children referred for a sleep study or control of continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) at the sleep laboratory of the Necker Hospital, Paris, France, between October 2015 and January 2016. The questionnaires evaluated anxiety and depression, family functioning, the parents' quality of life, daytime sleepiness and sleep quality RESULTS: The children had a mean age of seven ±5 years and most of the responses (79%) came from their mothers...

Maintenance of homeostasis in the respiratory and cardiovascular systems depends on reflexes that are initiated at specialized peripheral chemoreceptors that sense changes in the chemical composition of arterial blood. In mammals, the bilaterally-paired carotid bodies (CBs) are the main peripheral chemoreceptor organs that are richly vascularized and are strategically located at the carotid bifurcation. The CBs contribute to the maintenance of O2 , CO2 /H+ , and glucose homeostasis and have attracted much clinical interest because hyperactivity in these organs is associated with several pathophysiological conditions including sleep apnea, obstructive lung disease, heart failure, hypertension, and diabetes...

Objective: To investigate the predictive factors of mortality in extremely preterm infants. Methods: The retrospective case-control study was accomplished in the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University. A total of 268 extremely preterm infants seen from January 1, 1999 to December 31, 2015 were divided into survival group (192 cases) and death group (76 cases). The potential predictive factors of mortality were identified by univariate analysis, and then analyzed by multivariate unconditional Logistic regression analysis...

Obesity is often associated with obstructive sleep apnea (OSA), which increases the risk of intraoperative and postoperative complications. The role of preoperative screening of OSA is crucial, with adequate management based on continuous positive pressure before, during and after surgery. The obese patient is at risk of postoperative complications: difficult airway management, acute respiratory failure following extubation due to atelectasis and airway obstruction, added to morphine overdosing. Optimal management of difficult mask ventilation and intubation, protective ventilation, combined to the reduction of sedatives and analgesics and the sitting position as soon as possible with a postoperative monitoring should decrease the occurrence of complications...

Chronic lung allograft dysfunction (CLAD) remains the leading cause of morbidity and mortality after lung transplantation. Diagnosis requires spirometric change, that becomes increasingly difficult with advancing CLAD. Fourier decomposition MRI (FD-MRI) permits acquisition of ventilated-weighted images during free-breathing. This study evaluates FD-MRI in detecting CLAD in selected patients after bilateral lung transplantation (DLTx). DLTx recipients demonstrating CLAD at various stages participated. Radiologists remained blinded to clinical status until completion of image analysis...

Indoor environments provide important protective habitats for humans, who live or work in them most of the time. Many of these environments lack ventilation, which affects the composition of microbial communities, especially that of the fungal community. The aim of this study is to report the isolation of Aspergillus section Candidi from indoor environments of the School of Medicine at Universidad de Valparaiso, Chile, and identification through morpho-physiological and molecular approaches. Their ecological and clinical features were highlighted...

BACKGROUND: The benefits of lung-protective ventilation (LPV) with a low tidal volume (6 mL/kg of ideal body weight [IBW]), limited plateau pressure (< 28-30 cm H2 O), and appropriate positive end-expiratory pressure (PEEP) in patients with acute respiratory distress syndrome have become apparent and it is now widely adopted in intensive care units. Recently evidence for LPV in general anaesthesia has been accumulated, but it is not yet generally applied by anaesthesiologists in the operating room...

Adenoidectomy and tonsillectomy are commonly performed at the time of myringotomy plus ventilation tube insertion (MVTI) in children with otitis media with effusion (OME). However, the evidence supporting this practice is not conclusive. This is because uncertainty remains regarding the pathogenic role of the adenoids in OME. It is unclear if mechanical obstruction is a more or less important factor than the adenoids' role as a bacterial reservoir. Some studies show that children who have large adenoids removed have higher rates of effusion resolution compared to those children with small adenoids...

BACKGROUND In the general population, swine influenza is a self-limited infection. Patients after kidney transplantation, however, are at increased risk for complications and mortality from influenza A (H1N1). Acute respiratory distress syndrome (ARDS) complicates up to 55% of influenza-related pneumonia in hospitalized patients and carries a mortality of 40-46%. We describe our experience in intensive care of kidney transplant patients with ARDS complicating influenza A (H1N1) pneumonia during a flu outbreak...

Acute respiratory distress syndrome (ARDS) is a deadly complication in critically ill patients that causes significant morbidity and mortality. Patients with ARDS are seen across intensive care unit settings, with treatment being largely supportive involving techniques through mechanical ventilation. Using low-tidal-volume ventilation is a standard of practice for patients with ARDS, as a lung protection strategy; however, alveolar decruitment may occur. Recruitment maneuvers can recruit collapsed alveoli and promote oxygenation...
