BACKGROUND AND OBJECTIVE: Lung biopsies from patients with hypersensitivity pneumonitis (HP) have demonstrated small airway (SA) involvement, but there is no information concerning SA function in HP, and it is unknown whether pharmacological treatment could modify its function. SA function in patients with chronic HP using ultrasonic pneumography (UPG) and impulse oscillometry (IOS) was explored. We also compared initial results with those obtained after 4 weeks of standardized treatment with azathioprine and prednisone...

BACKGROUND: Acute respiratory distress syndrome (ARDS) is related to high mortality and morbidity. There are no proven therapeutic measures however, to improve the clinical course of ARDS, except using low tidal volume ventilation. Metformin is known to have pleiotropic effects including anti-inflammatory activity. We hypothesized that pre-admission metformin might alter the progress of ARDS among intensive care unit (ICU) patients with diabetes mellitus (DM). METHODS: We performed a retrospective cohort study from January 1, 2005, to April 30, 2005 of patients who were admitted to the medical ICU at Seoul National University Hospital because of ARDS, and reviewed ARDS patients with DM...

Over the last 20 years, noninvasive ventilation (NIV) strategies have been used with increasing frequency. The ease of use of NIV makes it applicable to patients presenting in a variety of types of respiratory distress. In this review, the physiology of positive pressure ventilation is discussed, including indications, contraindications, and options for mask type and fit. Characteristics of patients who are most likely to benefit from NIV are reviewed, including those in respiratory distress from chronic obstructive pulmonary disease exacerbation and cardiogenic pulmonary edema...

OBJECTIVE: To explore the prognostic factors of intensive care unit (ICU) patients. METHODS: A retrospective cohort study was conducted. The clinical data of patients admitted to ICU of Beijing Geriatric Hospital from January 2005 to December 2016 were collected. According to the prognosis, the patients were divided into death group and survival group, and the mortality trend with time and age was observed. Survival and death were treated as dependent variables, while the gender, age, reason of ICU admission, acute physiology and chronic health evaluation II (APACHE II) score, whether undergoing invasive mechanical ventilation (MV), invasive MV reason, duration of invasive MV, whether successful weaning, whether ICU nosocomial infection, hospital acquired pneumonia (HAP), central line-associated bloodstream infection (CLABSI), acute kidney injury (AKI) occurred, whether undergoing continuous blood purification (CBP), whether septic shock occurred, whether undergoing invasive hemodynamic monitoring or blood transfusion and length of ICU stay were used as the independent variables...

BACKGROUND: Double valve surgery is associated with an increased peri-operative morbidity and mortality. A less invasive right thoracotomy approach may be a viable alternative to median sternotomy surgery in these higher-risk patients. METHODS: We retrospectively analyzed the baseline demographics, operative characteristics, and post-operative outcomes of patients who underwent minimally invasive double valve surgery between January 2009 and December 2011 at our institution...

Previous studies suggest that chronic erythropoietin (Epo) deficiency in male mice does not alter normoxic/hypoxic ventilation. As effects of Epo are sex specific and as progesterone could be a respiratory stimulant, we evaluated the impact of Epo deficiency and its possible interaction with progesterone in ventilatory control in female mice during estrous cycle phases. Compared to wild type (WT) animals, Epo-TAg(h) female mice exhibited higher ventilation in hypoxia. However, when data were separated into luteal and follicular phases of the estrous cycle, basal ventilation and hypoxic ventilation were not different in both mice strains...

Pain is an unwelcome sleep partner. Pain tends to erode sleep quality and alter the sleep restorative process in vulnerable patients. It can contribute to next-day sleepiness and fatigue, affecting cognitive function. Chronic pain and the use of opioid medications can also complicate the management of sleep disorders such as insomnia (difficulty falling and/or staying asleep) and sleep-disordered breathing (sleep apnea). Sleep problems can be related to various types of pain, including sleep headache (hypnic headache, cluster headache, migraine) and morning headache (transient tension type secondary to sleep apnea or to sleep bruxism or tooth grinding) as well as periodic limb movements (leg and arm dysesthesia with pain)...

BACKGROUND: The proportion of survivors of acute respiratory failure is growing; yet, many do not regain full function and require prolonged admission in an acute or post-acute care facility. Little is known about their trajectory of functional recovery. We sought to determine whether prolonged admission influenced the trajectory of physical function recovery and whether patient age modified the recuperation rate. METHODS: We performed a secondary analysis of a randomized clinical trial of intensive physical therapy for patients with acute respiratory failure requiring mechanical ventilation for ≥4 days...

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease in which the amount of emphysema and airway disease may be very different between individuals, even in end-stage disease. Emphysema formation may be linked to the involvement of the small pulmonary vessels. The NAPDH oxidase (Nox) family is emerging as a key disease-related factor in vascular diseases, but currently its role in hypoxia-induced pulmonary remodelling in COPD remains unclear.Here we investigate the role of p22phox, a regulatory subunit of Nox, in COPD lungs, hypoxic pulmonary vasoconstriction (HPV), hypoxia-induced pulmonary vascular remodelling and pulmonary hypertension...

BACKGROUND: During septic shock, early development of hypertension after vasopressors weaning seems paradoxical. The aim of this study was to authenticate this empirical observation, identify associated factors and document its prognostic significance. METHODS: We conducted a descriptive, retrospective study in a medical ICU of a teaching hospital among adult patients with septic shock. RESULTS: From 01.01.2013 to 31.12.2014, 262 consecutive patients over 18 years of age were admitted because of septic shock; 195 of them were successfully weaned from vasopressors...

INTRODUCTION: The establishment of high-intensity (HI) noninvasive ventilation (NIV) that targets elevated PaCO2 has led to an increase in the use of long-term NIV to treat patients with chronic hypercapnic COPD. However, the role of the ventilation interface, especially in more aggressive ventilation strategies, has not been systematically assessed. METHODS: Ventilator settings and NIV compliance were assessed in this prospective cross-sectional monocentric cohort study of COPD patients with pre-existing NIV...

INTRODUCTION: Among survivors of intensive care, many remain dependent on mechanical ventilation and are discharged to long-term chronic ventilator units or to skilled nursing facilities. Few long-term outcome data are available on patients transferred from long-term chronic ventilator units. METHODS: We retrospectively followed subjects discharged from a long-term chronic ventilator unit from 2010-2012. We determined where these subjects went, evaluating whether location of discharge had an effect on mortality...

RATIONALE: Noninvasive ventilation (NIV) is a cornerstone of treatment for patients with severe exacerbations of chronic obstructive pulmonary disease (COPD) where it has been shown to reduce the need for intubation, hospital length of stay, and mortality. Despite high quality evidence and strong recommendations in clinical guidelines, use of NIV varies widely across hospitals. OBJECTIVE: To identify approaches used by hospitals which have been successful in implementing NIV to treat patients with severe exacerbations of COPD...

OBJECTIVES: Post-obstructive pulmonary edema is thought to occur from hemodynamic changes secondary to forced inspiration against the closed airway due to acute or chronic airway obstruction. We report a case of a 13 month-old boy who developed pulmonary edema from aspirated foreign body, nuts. METHODS: He underwent emergency bronchoscopy to confirm the clinical diagnosis of aspirated nuts in the trachea and nuts were removed endoscopically. His trachea was then intubated and he was mechanically ventilated with oxygen...
