INTRODUCTION: Assisted six-minute cycle test (A6MCT) distance was assessed in adults with muscular dystrophy (MD). METHODS: Forty-eight males, including Duchenne (DMD), limb-girdle (LGMD), fascioscapulohumeral (FSHD), Becker (BMD), and non-MD (CTRL), completed handgrip strength (HGS), lung function (FEV1, FVC), body fat and biceps thickness assessments. During the A6MCT, ventilation (VE), oxygen uptake (VO2 ), carbon dioxide (VCO2 ) and heart rate (HR) were recorded...

INTRODUCTION: Hemorrhagic shock is a major cause of death after trauma. An additional blunt chest trauma independently contributes to mortality upon the development of an acute lung injury (ALI) by aggravating pathophysiological consequences of hemorrhagic shock. The maintenance of hydrogen sulfide availability is known to play an important role during hemorrhage and ALI. We therefore tested the impact of a genetic 3-mercaptopyruvate sulfurtransferase mutation (Δ3-MST) in a resuscitated murine model of traumatic-hemorrhagic shock...

Infants born prematurely are particularly susceptible to respiratory illness due to underdeveloped lungs, which can often result in fatality. Preterm infants in acute stages of respiratory illness typically require mechanical ventilation assistance, and the efficacy of the type of mechanical ventilation and its delivery has been the subject of a number clinical studies. With recent advances in machine learning approaches, particularly deep learning, it may be possible to estimate future responses to mechanical ventilation in real-time, based on ventilation monitoring up to the point of analysis...

In thoracic surgery, the introduction of video-assisted thoracoscopic techniques has allowed the development of fast-track protocols, with shorter hospital lengths of stay and improved outcomes. The perioperative management needs to be optimized accordingly, with the goal of reducing postoperative complications and speeding recovery times. Premedication performed in the operative room should be wisely administered because often linked to late discharge from the post-anesthesia care unit (PACU). Inhalatory anesthesia, when possible, should be preferred based on protective effects on postoperative lung inflammation...

Little is known about the alcohol habits of people with advanced lung disease. Following lung transplantation patients are asked to abstain from or minimize alcohol use. The aim of this investigation is to assess alcohol use in a cohort of patients with advanced lung disease undergoing evaluation for lung transplant. This is a prospective observational investigation comparing patient self-report of alcohol use with their responses on the Alcohol Use Disorder and Identification Test, and alcohol biomarkers collected at the time of transplant...

Maintenance of homeostasis in the respiratory and cardiovascular systems depends on reflexes that are initiated at specialized peripheral chemoreceptors that sense changes in the chemical composition of arterial blood. In mammals, the bilaterally-paired carotid bodies (CBs) are the main peripheral chemoreceptor organs that are richly vascularized and are strategically located at the carotid bifurcation. The CBs contribute to the maintenance of O2 , CO2 /H+ , and glucose homeostasis and have attracted much clinical interest because hyperactivity in these organs is associated with several pathophysiological conditions including sleep apnea, obstructive lung disease, heart failure, hypertension, and diabetes...

Chronic lung allograft dysfunction (CLAD) remains the leading cause of morbidity and mortality after lung transplantation. Diagnosis requires spirometric change, that becomes increasingly difficult with advancing CLAD. Fourier decomposition MRI (FD-MRI) permits acquisition of ventilated-weighted images during free-breathing. This study evaluates FD-MRI in detecting CLAD in selected patients after bilateral lung transplantation (DLTx). DLTx recipients demonstrating CLAD at various stages participated. Radiologists remained blinded to clinical status until completion of image analysis...

BACKGROUND: The benefits of lung-protective ventilation (LPV) with a low tidal volume (6 mL/kg of ideal body weight [IBW]), limited plateau pressure (< 28-30 cm H2 O), and appropriate positive end-expiratory pressure (PEEP) in patients with acute respiratory distress syndrome have become apparent and it is now widely adopted in intensive care units. Recently evidence for LPV in general anaesthesia has been accumulated, but it is not yet generally applied by anaesthesiologists in the operating room...

BACKGROUND In the general population, swine influenza is a self-limited infection. Patients after kidney transplantation, however, are at increased risk for complications and mortality from influenza A (H1N1). Acute respiratory distress syndrome (ARDS) complicates up to 55% of influenza-related pneumonia in hospitalized patients and carries a mortality of 40-46%. We describe our experience in intensive care of kidney transplant patients with ARDS complicating influenza A (H1N1) pneumonia during a flu outbreak...

Acute respiratory distress syndrome (ARDS) is a deadly complication in critically ill patients that causes significant morbidity and mortality. Patients with ARDS are seen across intensive care unit settings, with treatment being largely supportive involving techniques through mechanical ventilation. Using low-tidal-volume ventilation is a standard of practice for patients with ARDS, as a lung protection strategy; however, alveolar decruitment may occur. Recruitment maneuvers can recruit collapsed alveoli and promote oxygenation...

Recently, side effects of plasma expanders like hydroxyethyl starch and gelatine gained considerable attention. Most studies have focused on the kidneys; lungs remain unconsidered. Isolated mouse lungs were perfused for 4 hours with buffer solutions based on hydroxyethyl starch (HES) 130/0.4, HES 200/0.5 or gelatine and ventilated with low or high pressure under physiological pH and alkalosis. Outcome parameters were cytokine levels and the wet-to-dry ratio. For cytokine release, murine and human PCLS were incubated in three different buffers and time points...

Idiopathic pulmonary fibrosis (IPF) is a fibrotic lung disease characterized by progressive loss of lung function and poor prognosis. The so-called acute exacerbation of IPF (AE-IPF) may lead to severe hypoxemia requiring mechanical ventilation in the intensive care unit (ICU). AE-IPF shares several pathophysiological features with acute respiratory distress syndrome (ARDS), a very severe condition commonly treated in this setting.A review of the literature has been conducted to underline similarities and differences in the management of patients with AE-IPF and ARDS...

BACKGROUND: Thoracic surgery for lung resection is associated with a high incidence of postoperative pulmonary complications. Controlled ventilation with a large tidal volume has been documented to be a risk factor for postoperative respiratory complications after major abdominal surgery, whereas the use of low tidal volumes and positive end-expiratory pressure (PEEP) has a protective effect. OBJECTIVE: To evaluate the effects of ventilation with low tidal volume and PEEP on major complications after thoracic surgery...

BACKGROUND: Coagulopathy and inflammation induced by hemorrhagic shock and traumatic injury are associated with increased mortality and morbidity. Vitamin C (VitC) is an antioxidant with potential protective effects on the pro-inflammatory and pro-coagulant pathways. We hypothesized that high-dose VitC administered as a supplement to fluid resuscitation would attenuate inflammation, coagulation dysfunction, and end-organ tissue damage in a swine model of polytrauma and hemorrhage. METHODS: Male Sinclair swine (n = 24; mean body weight 27 kg) were anesthetized, intubated, mechanically ventilated, and instrumented for physiological monitoring...
