INTRODUCTION: Primary Ciliary Dyskinesia (PCD) describes a group of inherited disorders that result in abnormal ciliary motion leading to mucous stasis. Clinical features include almost universally otitis media with effusion (OME), particularly in infants. PCD patients provide us with a cohort of patients with OME that is not treated with ventilatory tube (VT) insertion as these have been shown to result in frequent complications including chronic otorrhoea, early extrusion and persistent perforation without significant improvement to hearing in the long term...

 Background: Exercise adherence in already low-active older adults with and without mild cognitive impairment (MCI) remains low. Perceptual regulation and exergaming may facilitate future exercise behaviour by improving the affective experience, however evidence that this population can perceptually regulate is lacking. To explore this, we investigated 1) perceptual regulation of exercise intensity during either exergaming or regular ergometer cycling and 2) explored affective responses...

Quercetin (QU) is one of the most common flavonoids that are present in a wide variety of fruits, vegetables, and beverages. This compound possesses potent anti-inflammatory and anti-oxidant properties. Supplemental oxygen is routinely administered to premature infants with pulmonary insufficiency. However, hyperoxia is one of the major risk factors for the development of bronchopulmonary dysplasia (BPD), which is also termed chronic lung disease in premature infants. Currently, no preventive approaches have been reported against BPD...

Acute respiratory distress syndrome (ARDS) is the most severe form of acute respiratory failure characterized by diffuse alveolar and endothelial damage. The severe pathophysiological changes in lung parenchyma and pulmonary circulation together with the effects of positive pressure ventilation profoundly affect heart lung interactions in ARDS. The term pulmonary vascular dysfunction (PVD) refers to the specific involvement of the vascular compartment in ARDS and is expressed clinically by an increase in pulmonary arterial (PA) pressure and pulmonary vascular resistance both affecting right ventricular (RV) afterload...

The term "respiratory insufficiency" (RI) describes the inability of an organism to maintain the gas exchange between the ambient air and its peripheral organs. This causes a hypoxia and hypercapnia. The mechanisms that lead to RI are either an impaired gas exchange in the lung tissue or an alveolar hypoventilation caused by an insufficient ventilatory pump. Thus the RI is divided into a hypoxic or a hypercapnic RI. The diagnostic procedure for RI contains several examinations. One key aspect of the exploration is the identification of potential reversible and thus correctable reasons of the RI...

Background: Outcomes for patients with ST-segment elevation myocardial infarction continue to improve, largely due to timely provision of reperfusion by primary percutaneous coronary intervention (PPCI). However, despite prompt and successful PPCI, a small proportion of patients require ventilatory and hemodynamic support in an intensive care unit (ICU). The outcome of these patients remains poorly defined. Methods: A retrospective review of all consecutive admissions post-PPCI pathway to a single ICU between January 2009 and May 2014 was performed...

INTRODUCTION: Cough exceeding 3-8 weeks was defined as chronic cough in various guides. Asthma is the most common cause of chronic-specific cough. Causes other than asthma include prolonged bacterial bronchitis and upper airway cough syndrome (UACS). Nitric oxide (NO) causes vascular smooth muscle relaxation, bronchodilation, and oxidant effects via its metabolite, peroxynitrite. An increase in NO results in inflammation, vasodilatation, and bronchial edema. MATERIALS AND METHODS: The study group included 90 patients aged 6-17 years selected from individuals presenting to the Pediatric Immunology and Allergic Diseases Clinic with cough persisting for 4 weeks and 30 other patients representing to the control group...

The aim of this study was to investigate the effects of 3 weeks high-intensity interval training (HIIT) on ventilatory efficiency (VE/VCO2 slope) in endurance athletes. Sixteen male well-trained (67.72 ml kg min-1) athletes participated in this study. Each participant performed an incremental exercise test with gas analysis (i.e. VE, VO2) and a 400 m running field test (T400m) before and after the 3 weeks intervention period. HIIT group (HIITG) performed 11 HIIT sessions consisting of four 4-min interval bouts at an exercise intensity of 90-95% of the VO2max, separated by 4-min active recovery periods (work/rest ratio = 1:1)...

BACKGROUND: Opiate-induced respiratory depression is sexually dimorphic and associated with increased risk among the obese. The mechanisms underlying these associations are unknown. The present study evaluated the two-tailed hypothesis that sex, leptin status, and obesity modulate buprenorphine-induced changes in breathing. METHODS: Mice (n = 40 male and 40 female) comprising four congenic lines that differ in leptin signaling and body weight were injected with saline and buprenorphine (0...

Acute exacerbation(s) of chronic obstructive pulmonary disease (AECOPD) tend to be critical and debilitating events leading to poorer outcomes in relation to chronic obstructive pulmonary disease (COPD) treatment modalities, and contribute to a higher and earlier mortality rate in COPD patients. Besides pro-active preventative measures intended to obviate acquisition of AECOPD, early recovery from severe AECOPD is an important issue in determining the long-term prognosis of patients diagnosed with COPD. Updated GOLD guidelines and recently published American Thoracic Society/European Respiratory Society clinical recommendations emphasize the importance of use of pharmacologic treatment including bronchodilators, systemic steroids and/or antibiotics...

Sepsis and septic shock are each commonly accompanied by acute respiratory failure and the need for invasive as well as non-invasive ventilation throughout a patient's intensive care unit course. We explore the underpinnings of acute respiratory failure of pulmonary as well as non-pulmonary origin in the context of invasive and non-invasive management approaches. Both pharmacologic and non-pharmacologic adjuncts to ventilatory and oxygenation support are highlighted as well. Finally, rescue modalities are positioned within the intensivist's armamentarium for global care of support of the critically ill or injured patient with sepsis or septic shock...

The severity of X-linked myotubular myopathy (XLMTM) ranges from mild to severe, depending on the level of ventilatory support required. Patients with the severe form of XLMTM usually die within the first year of life due to respiratory failure. Most survivors need tracheostomies, and there has only been one report about the use of non-invasive positive pressure ventilation (NPPV) in patients with the severe form of XLMTM because of the severity of the associated respiratory failure. We successfully applied NPPV with high-span positive inspiratory pressure (PIP) in a patient with the severe form of XLMTM, who also had secondary pectus excavatum...

PURPOSE: Recent examinations have shown lower maximal oxygen uptake (VO2max) during traditional ramp (RAMP) compared to self-paced (SPV) graded exercise testing (GXT) attributed to differences in cardiac ouput. The current study examined the differences in hemodyamic and metabolic responses between RAMP and SPV during treadmill exercise. METHODS: Sixteen recreationally trained men (23.7±3.0 yrs) completed two separate treadmill GXT protocols. SPV consisted of five 2-min stages (10 min total) of increasing speed clamped by the Borg RPE6-20 scale...

BACKGROUND: Harmful effects of spontaneous breathing have been shown in experimental severe acute respiratory distress syndrome (ARDS). However, in the clinical setting, spontaneous respiration has been indicated only in mild ARDS. To date, no study has compared the effects of spontaneous assisted breathing with those of fully controlled mechanical ventilation at different levels of positive end-expiratory pressure (PEEP) on lung injury in ARDS. OBJECTIVE: To compare the effects of assisted pressure support ventilation (PSV) with pressure-controlled ventilation (PCV) on lung function, histology and biological markers at two different PEEP levels in mild ARDS in rats...
