#1
Enoch W K Lam, Frances Chung, Jean Wong
Sleep-disordered breathing (SDB) is highly prevalent in the general population and has been associated with cognitive impairment in older individuals. Delirium is an acute decline in cognitive function and attention that often occurs after surgery, especially in older individuals. Several recent studies suggest an association between SDB and postoperative delirium. The aim of this systematic review is to examine the current literature on SDB, postoperative delirium, and cognitive impairment and to discuss the pathophysiology and perioperative considerations...

BACKGROUND: Holding chambers or spacers can enhance the efficacy of pressurized metered dose inhalers (pMDI) in delivering inhaled medications, as they reduce the need for hand-breath coordination and improve lower airways deposition. Nevertheless, their cost can be high for patients in low-income countries. OBJECTIVE: To compare asthma control achieved with beclomethasone-dipropionate administered through a hydrofluoroalkane-driven pMDI (BDp-pMDI) coupled to a home-made spacer (HmS) or to a valved commercial spacer (VCS) as auxiliary devices...

Emma D Deeks, Guy Brusselle
Reslizumab (Cinqaero(®); Cinqair(®)) is a humanized monoclonal antibody against interleukin-5 (IL-5), a cytokine mediator of eosinophilic airway inflammation. Reslizumab is indicated as an add-on treatment for severe eosinophilic asthma in adults, on the basis of data from the BREATH phase III clinical trial programme. In three double-blind BREATH studies of up to 52 weeks' duration, adding intravenous reslizumab (3 mg/kg, once every 4 weeks) to the current asthma therapy of patients (aged 12-75 years) with eosinophilic asthma inadequately controlled with inhaled corticosteroids resulted in significant reductions in clinical asthma exacerbation frequency and significant improvements in lung function, asthma control and health-related quality of life relative to adding placebo...

Study Objectives: To determine whether arousals that terminate obstructive events in obstructive sleep apnea (OSA): 1. Induce hypocapnia and 2. Subsequently reduce genioglossus muscle activity following the return to sleep. Methods: 31 untreated OSA patients slept instrumented with: sleep staging electrodes, nasal mask and pneumotachograph, end-tidal CO2 monitoring and intramuscular genioglossus electrodes. End-tidal CO2 was monitored and respiratory arousals were assigned an end-arousal CO2 change value (PETCO2 on the last arousal breath minus each individual's wakefulness PETCO2)...

BACKGROUND: Divers try to limit risks associated with their sport, for instance by breathing enriched air nitrox (EANx) instead of air. This double blinded, randomized trial was designed to see if the use of EANx could effectively improve cognitive performance while diving. METHODS: Eight volunteers performed two no-decompression dry dives breathing air or EANx for 20 min at 0.4 MPa. Cognitive functions were assessed with a computerized test battery, including MathProc and Ptrail...

A full-size manikin dressed in fire-resistant coveralls coated in 120 grams of sodium bicarbonate was randomly given one of three treatments for dry aerosol decontamination. The three treatments were high-efficiency particulate air (HEPA) vacuum, a commercially-available air shower, and the no treatment control. Immediately after the treatment, the coveralls were doffed and an air sample was taken in the breathing zone of the manikin to estimate airborne total and respirable dust concentrations to an unprotected worker post decontamination...

Research reveals cardiac regeneration exists at levels previously deemed unattainable. Clinical trials using stem cells demonstrate promising cardiomyogenic and regenerative potential but insufficient contractile recovery. Incomplete understanding of the biology of administered cells likely contributes to inconsistent patient outcomes. Metabolism is a core component of many well-characterized stem cell types, and metabolic changes fundamentally alter stem cell fate from self-renewal to lineage commitment, and vice versa...

OBJECTIVE: Fatigue and other treatment-related symptoms are critical therapeutic targets for improving quality of life in patients with colorectal cancer during chemotherapy. Yoga is a promising intervention for improving these therapeutic targets and has been primarily investigated in the group-class format, which is less feasible for cancer patients with high symptom burden to attend. Thus, we developed a protocol for implementing yoga individually in the clinic among patients receiving chemotherapy...

Systemic inflammatory response syndrome (SIRS) is observed during critical illness in most patients. It is defined by a clinical definition. The composition of volatile organic compounds (VOCs) in exhaled breath may change during SIRS and may thus serve as a diagnostic tool. We investigated whether exhaled breath VOCs can serve as biomarker for SIRS in a human model of endotoxemia. Eighteen healthy volunteers received 2 ng Eschericia coli lipopolysaccharide (LPS) kg(-1) body weight intravenously. Venous blood and exhaled breath were collected before infusion of LPS and every 2 h thereafter, up to 8 h after infusion...

Heart failure (HF) and chronic obstructive pulmonary disease (COPD) are two common, heterogeneous, long-term illnesses which cause significant morbidity and mortality. Although they both present with breathlessness, they are treated differently. Treatment of COPD focuses mainly on relieving short-term breathlessness, whilst treatment of HF has focused on long term morbidity and mortality. Areas covered: In this review, we aim to highlight the diagnostic challenges in distinguishing COPD from HF. We also explore the implications of their overlap, and the use of biomarkers and treatments for HF in patients with COPD to improve long-term outcomes...

The study examined the interactive effects of a 10-day exposure to hypoxia and bedrest on the whole body peak oxygen uptake (V˙O2 peak ) during maximal exercise, and on skeletal-muscle and cerebral oxygenation during submaximal exercise. Nine males underwent three 10-day confinements, in a Latin-square order: (i) a normoxic bedrest [NBR; partial pressure of inspired O2 (PI O2 ) = 134.2 ± 0.7 mmHg], (ii) a hypoxic bedrest (HBR; PI O2  = 102.9 ± 0.1 mmHg at day 1, 91.5 ± 1.2 mmHg at days 3-10), and (iii) a hypoxic ambulation (HAMB; PI O2 as in HBR)...

PURPOSE: Early noninvasive ventilation (NIV) after extubation decreases the risk of respiratory failure and lowers 90-day mortality in patients with hypercapnia. Patients with chronic respiratory disease are at risk of extubation failure. Therefore, it could be useful to determine the role of NIV with a discontinuous approach, not limited to patients with hypercapnia. We assessed the efficacy of early NIV in decreasing respiratory failure after extubation in patients with chronic respiratory disorders...

Wittstatt Alexandra Whitaker-Lea, Alex B Valadka
Traumatic brain injury (TBI) continues to be a major public health problem. Proposed treatments have not withstood testing in clinical trials because of failure to account for different types of TBI and other weaknesses in trial design. Management goals continue to be prevention and prompt treatment of secondary insults (hypotension, hypoxia, and other physiologic derangements). This goal is best accomplished by careful attention to airway, breathing, circulation, and basic principles of intensive care unit management...

According to evidence from recent decades, multicomponent programs of psychological intervention in people with chronic pain have reached the highest levels of efficacy. However, there are still many questions left to answer since efficacy has mainly been shown among upper-middle class patients in English-speaking countries and in controlled studies, with expert professionals guiding the intervention and with a limited number of domains of painful experience evaluated. For this study, a program of multicomponent psychological intervention was implemented: (a) based on techniques with empirical evidence, but developed in Spain; (b) at a public primary care center; (c) among patients with limited financial resources and lower education; (d) by a novice psychologist; and (e) evaluating all domains of painful experience using the instruments recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT)...

A single high-fat meal (HFM) leads to an increase in triglycerides and oxidative stress. Oxidative stress can be assessed via 8-isoprostane generation, which is associated with the development of asthma and cardiovascular disease. No previous research has investigated whether airway and systemic 8-isoprostane increases postprandially in nonasthmatic participants according to the energy and fat content of a meal. Our purpose was to assess airway and systemic 8-isoprostane after a HFM and a true-to-life moderate-fat meal (MFM)...
