: Persistent respiratory or feeding problems in children may be associated with a congenital vascular ring. Surgical management is fairly standardized, but long-term outcomes are not well described. This study aims to investigate clinical presentation, surgical treatment, and risk factors for early mortality and late outcome. Our database revealed 62 surgically treated vascular ring patients between 1993 and 2014. Double aortic arch was the most common diagnosis (53%). Median age at operation was 1 year...

We conducted an international study to evaluate practices in the diagnosis and management of patients with chronic thromboembolic pulmonary hypertension (CTEPH) globally across different regions. Between August and October 2012, CTEPH-treating physicians completed a 15-minute online questionnaire and provided patient record data for their 2-5 most recent patients with CTEPH. Overall, 496 physicians (Europe: 260; United States: 152; Argentina: 52; Japan: 32) completed the questionnaire and provided patient record data for 1,748 patients...

BACKGROUND: Hospitalization of patients with chronic obstructive pulmonary disease (COPD) places a huge healthcare burden. Positive airway pressure (PAP) therapy is sometimes used in COPD patients, but the possible impact on hospitalization risk remains controversial. We studied the hospitalization risk of COPD patients before and after initiation of various PAP therapies in a "real-world" bioinformatics study. METHODS: We performed a retrospective analysis of administrative claims data of hospitalizations in patients with COPD who received or did not receive PAP therapy - continuous PAP, bilevel PAP, and non-invasive positive pressure ventilation using a home ventilator (NIPPV)...

OBJECTIVE: Thoraco-abdominal aortic aneurysm (TAAA) repair is a complex procedure performed in patients at high cardiovascular risk. High volume intra-operative bleeding is often recorded, and the amount of intra-operative blood product transfusion is associated with relevant morbidity and mortality. The aim of the study was to identify pre-operative predictors of intra-operative large volume blood transfusions (LVBT) to stratify patients pre-operatively. METHODS: This was a retrospective analysis of prospectively collected data of all patients who underwent open TAAA surgery at San Raffaele Scientific Institute from January 2009 to December 2015...

Nutritional deficiencies are very common among the patient on chronic hemodialysis. But they can be easily overlooked or misdiagnosed. Deficiencies of trace elements and phosphorous is rare among this patient population but if neglected can lead to catastrophic effects. We describe a case report of a patient with ESRD recently started on outpatient maintenance hemodialysis, who presented with life threatening muscular weakness with respiratory failure requiring prolonged mechanical ventilation. On initial workup, it was unclear what the cause of her weakness was, however, further investigations showed undetectable phosphorous levels as well as very low levels of trace elements...

BACKGROUND: Acute kidney injury (AKI) is a common morbidity after off-pump coronary revascularization. We investigated whether perioperative administration of sodium bicarbonate, which might reduce renal injury by alleviating oxidative stress in renal tubules, prevents postoperative AKI in off-pump coronary revascularization patients having renal risk factors. METHODS: Patients (n=162) having at least one of the following AKI risk factors were enrolled: (i) age >70 yr; (ii) diabetes mellitus; (iii) chronic renal disease; (iv) congestive heart failure or left ventricular ejection fraction <35%; and (v) reoperation or emergency...

BACKGROUND: There are various reasons why weaning and extubation failure occur, but ineffective cough and secretion retention can play a significant role. Cough augmentation techniques, such as lung volume recruitment or manually- and mechanically-assisted cough, are used to prevent and manage respiratory complications associated with chronic conditions, particularly neuromuscular disease, and may improve short- and long-term outcomes for people with acute respiratory failure. However, the role of cough augmentation to facilitate extubation and prevent post-extubation respiratory failure is unclear...

BACKGROUND: The impact of various aerosol delivery devices on patient outcomes during mechanical ventilation is unknown. If one method of delivery results in a higher ventilator-associated pneumonia (VAP) rate than another, multiple patient outcomes may be affected. This study aimed to determine whether there was a difference in VAP occurrence and patient outcomes (days receiving ventilation and in-hospital mortality) between the vibrating mesh nebulizer (AeroNeb Solo) and the metered-dose inhaler (MDI)...

Bronchopulmonary dysplasia (BPD) is a chronic lung disease most commonly seen in premature infants who required mechanical ventilation and oxygen therapy for acute respiratory distress. While advances in neonatal care have resulted in improved survival rates of premature infants, limited progress has been made in reducing rates of BPD. Lack of progress may in part be attributed to the limited therapeutic options available for prevention and treatment of BPD. Several lung-protective strategies have been shown to reduce risks, including use of non-invasive support, as well as early extubation and volume ventilation when intubation is required...

Various pathophysiological conditions such as surfactant dysfunction, mechanical ventilation, inflammation, pathogen products, environmental exposures and gastric acid aspiration stress lung cells and the compromise of plasma membranes occur as a result. The mechanisms necessary for cells to repair plasma membrane defects have been extensively investigated in the last two decades, and some of these key repair mechanisms are also shown to occur following lung cell injury. As it was theorized that lung wounding and repair are involved in the pathogenesis of acute respiratory distress syndrome (ARDS) and idiopathic pulmonary fibrosis (IPF), in this review, we summarized the experimental evidence of lung cell injury in these two devastating syndromes, discuss relevant genetic, physical and biological injury mechanisms, as well as mechanisms utilized by lung cells for cell survival and membrane repair...

Chronic thromboembolic pulmonary hypertension (CTEPH) is one of the potentially curable causes of pulmonary hypertension and is definitively treated with pulmonary thromboendartectomy. CTEPH can be overlooked, as its symptoms are nonspecific and can be mimicked by a wide range of diseases that can cause pulmonary hypertension. Early diagnosis of CTEPH and prompt evaluation for surgical candidacy are paramount factors in determining future outcomes. Imaging plays a central role in the diagnosis of CTEPH and patient selection for pulmonary thromboendartectomy and balloon pulmonary angioplasty...

BACKGROUND: Platelets are commonly transfused to critically ill patients. Reports suggest an association between platelet transfusion and infection. However, there is no large study to have determined whether platelet transfusion in critically ill patients is associated with hospital-acquired infection. METHODS: We conducted a multi-centre study using prospectively maintained databases of two large academic intensive care units (ICUs) in Australia. Characteristics of patients who received platelets in ICUs between 2008 and 2014 were compared to those of patients who did not receive platelets...

Importance: Acute respiratory failure (ARF) is a life-threatening event that has been linked in case reports to antipsychotic use, but this association lacks population-based evidence. Particular attention should be focused on patients with chronic obstructive pulmonary disease (COPD) regarding this drug safety concern because these patients are prone to ARF and are commonly treated with antipsychotics. Objective: To determine whether the use of antipsychotics is associated with an increased risk of ARF in patients with COPD...
