Seasonal influenza epidemics remain a considerable burden in adults, especially in those at higher risk of complications. The aim of this study was to determine the costs associated with influenza-related hospitalization in patients aged ≥65 years admitted to 20 hospitals from seven Spanish regions during the 2013-14 and 2014-15 influenza seasons. Bivariate analysis was used to compare costs in vaccinated and unvaccinated cases. Costs were calculated according to the Spanish National Health System diagnosis-related group tables for influenza and other respiratory system conditions (GRD 89 and GRD 101)...

INTRODUCTION: Approximately 50% of patients with sepsis-induced acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) require mechanical ventilation. Patients with extended mechanical ventilator use routinely develop re-infections, which increases hospital stay, mortality, and health care cost. Some studies have pointed out inflammatory factors concentrations can affect ventilator weaning, but do not indicate changed inflammatory factors related to ventilator weaning during using ventilators...

BACKGROUND: The aim of this study was to identify risk factors associated with mortality in patients re-admitted to an intensive care unit (ICU) after initial recovery from major lung resection. METHODS: We retrospectively reviewed the case records of all patients who underwent major lung resection between February 2011 and May 2013. A total of 1916 patients underwent major resection surgery for various lung diseases, 63 (3.3%) of which required ICU admission after initial recovery...

Minimal invasive extracorporeal circulation (MiECC) has initiated important new efforts within science and technology towards a more physiologic perfusion. In this study, we aim to investigate the learning curve of our center regarding MiECC. We studied a series of 150 consecutive patients who underwent elective coronary artery bypass grafting by the same surgical team during the initial phase of MiECC application. Patients were randomly assigned into two groups. Group A (n = 75) included patients operated on MiECC, while group B (n = 75) included patients operated with conventional cardiopulmonary bypass (cCPB)...

Acute respiratory distress syndrome occupies a great deal of attention in intensive care units. Despite ample knowledge of the physiopathology of this syndrome, the focus in intensive care units consists mostly of life-supporting treatment and avoidance of the side effects of invasive treatments. Although great advances in mechanical ventilation have occurred in the past 20 years, with a significant impact on mortality, the incidence continues to be high. Patients with acute respiratory distress syndrome, especially the most severe cases, often present with refractory hypoxemia due to shunt, which can require additional treatments beyond mechanical ventilation, among which is mechanical ventilation in the prone position...

BACKGROUND: Decedent older adults with dementia are increasingly less likely to die in a hospital, though escalation of care to a hospital setting, often including critical care, remains common. Although hospice is increasingly reported as the site of death in these patients, the factors associated with transition to hospice care during end-of-life (EOL) hospitalizations of older adults with dementia and the extent of preceding escalation of care to an intensive care unit (ICU) setting among those discharged to hospice have not been examined...

BACKGROUND: Patients who have undergone cardiac surgery are generally mechanically ventilated postoperatively. Early postoperative extubation is currently recommended in anesthesia guidelines. No current technology can accurately, non-invasively, measure respiratory competence after extubation. Pulse oximetry has been helpful, but this is a late indicator of respiratory compromise. A novel, non-invasive, respiratory volume monitor (RVM) has been shown to deliver accurate continuous, real-time minute ventilation (MV), tidal volume (TV) and respiratory rate (RR) measurements and provide an objective measure of respiratory competence...

Heterogeneity in regional end expiratory lung volume (EELV) may lead to variations in regional strain (ε). High ε levels have been associated with ventilator-associated lung injury (VALI). While both whole lung and regional EELV may be affected by changes in positive end-expiratory pressure (PEEP), regional variations are not revealed by conventional respiratory system measurements. Differential rates of deflation of adjacent lung units due to regional variation in expiratory time constants (τE) may create localized regions of ε that are significantly greater than implied by whole lung measures...

BACKGROUND: Early enteral nutrition is recommended for mechanically ventilated patients in several studies and guidelines. In contrast, the effects of early enteral nutrition on noninvasive ventilation (NIV) have not been investigated extensively. The lack of an established method of airway protection suggests that enteral nutrition administration to these patients could increase airway complications and worsen outcomes. METHODS: Between January 2007 and January 2015, 150 patients were admitted to our respiratory department for acute respiratory failure and received NIV for >48 h...

Objective Identify the progression of specific signs of multiorgan dysfunction among infants with fatal sepsis. Study Design Cohort study of 679 infants who died within 3 days of the start of a late-onset sepsis (LOS) episode in neonatal intensive care units from 1997 to 2012. We extracted clinical and laboratory data on the day of death (day 0) and the preceding 5 days (days -5 to -1). Results Median (25th percentile-75th percentile) gestational age was 25 (24-28) weeks. Compared with day -1, day 0 was characterized by an increased requirement for mechanical ventilation and higher mean fraction of inspired oxygen...

OBJECTIVE: This study aimed to evaluate the impact of early tracheostomy (ET, ≤7 days) versus that of late tracheostomy (LT, >7 days) on outcomes such as hospital length of stay (LOS), intensive care unit (ICU) days, mechanical ventilation (MV) days, and mortality ratio. METHODS: A historical cohort study was undertaken using charts of patients admitted to the Puerto Rico Trauma Hospital who required MV and underwent tracheostomies, from 2000 to 2013. A logistic regression was performed to evaluate the association between timing of tracheostomy and complications and mortality...

INTRODUCTION The prevalence of frailty (diminished physiologic reserve) and its effect on outcomes for those ≥18 years old with critical illness is unclear. We hypothesized greater frailty would be associated with subsequent mortality, disability, and cognitive impairment, regardless of age. METHODS At enrollment, we measured frailty using the Clinical Frailty Scale (CFS, range 1 [very fit] to 7 [severely frail]). At 3 and 12 months post-discharge, we assessed vital status, instrumental and basic activities of daily living (IADLs and BADLs), and cognition...

RATIONALE: The diaphragm is the major inspiratory muscle and is assumed to relax during expiration. However, electrical post-inspiratory activity has been observed. Whether or not there is an expiratory diaphragmatic contraction that preserves lung patency has yet to be explored. OBJECTIVE: We hypothesized the occurrence of an expiratory diaphragmatic contraction directed at stabilizing peripheral airways and preventing or reducing cyclic expiratory lung collapse...

BACKGROUND: Lung recruitment maneuver induces a decrease in stroke volume, which is more pronounced in hypovolemic patients. The authors hypothesized that the magnitude of stroke volume reduction through lung recruitment maneuver could predict preload responsiveness. METHODS: Twenty-eight mechanically ventilated patients with low tidal volume during general anesthesia were included. Heart rate, mean arterial pressure, stroke volume, and pulse pressure variations were recorded before lung recruitment maneuver (application of continuous positive airway pressure of 30 cm H2O for 30 s), during lung recruitment maneuver when stroke volume reached its minimal value, and before and after volume expansion (250 ml saline, 0...

Neuroblastoma (NB) is the most frequently diagnosed neoplasm during infancy and its incidence declines within the first 3-5 years of life. It can be rarely diagnosed in adolescents and young adults. Adolescents have advanced stage of disease, higher frequency of uncommon metastatic sites such as lungs, and worse outcomes. Herein, we describe an unusual case of NB in a 17-year-old adolescent presented with lung metastasis at diagnosis. The patient was diagnosed with stage IV NB. Thorax high-resolution computed tomography (HRCT) scan revealed irregular septal thickening with ground glass opacity consistent with pulmonary parenchymal metastases...

Nebulized antibiotics use has become common practice in the therapeutics of pneumonia in cystic fibrosis patients. There is an increasing interest in their use for respiratory infections in mechanically ventilated (MV) patients in order to a) overcome pharmacokinetic issues in the lung compartment with traditional systemic antibiotic use and b) prevent the emergence of multi-drug-resistant (MDR) pathogens. Areas covered: The beneficial effects of antibiotic nebulization in MV patients e.g. increasing efficacy, reduced toxicity and prevention of resistance are described...

Botulism toxin injection (BTI) is a well-known and relatively safe endoscopic treatment for achalasia. We report a case of a 90-year-old female diagnosed with achalasia who subsequently underwent BTI with symptomatic relief. The therapy was complicated by systemic botulism, however, leading to progressive muscle paralysis with diaphragmatic involvement requiring mechanical ventilation support. This is the first reported case of BTI for achalasia causing systemic botulism.

BACKGROUND: Age remains a significant and unmodifiable risk factor for cardiovascular diseases, and an increasing number of patients older than 80 years of age undergo Coronary Artery Bypass Grafting (CABG). Old age is also an independent risk factor for postoperative complications. The aim of this study is to describe the population of patients 80 years of age or older who underwent CABG procedure and to assess the mortality rate and risk factors for in-hospital mortality. METHODS: A retrospective case-series study analyzing 388 consecutive patients aged 80 years of age or older who underwent isolated CABG procedure between 2010 and 2014 in the Department of Cardiovascular Surgery and Transplantology, John Paul II Hospital, Krakow...

INTRODUCTION: Clinicians routinely administer stress ulcer prophylaxis to mechanically ventilated patients in the intensive care unit (ICU), most commonly prescribing proton pump inhibitors (PPIs). However, the incidence of gastrointestinal (GI) bleeding from stress ulceration is low and recent observational studies suggest these agents may increase infections. Therefore, a large randomized clinical trial (RCT) is needed to inform modern practice. The aim of this multicenter pilot trial is to determine the feasibility of performing a large RCT to investigate the efficacy and safety of withholding intravenous pantoprazole...
