Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are associated with high morbidity and mortality. Menstrual blood-derived stem cells (MenSCs) have been shown to be good therapeutic tools in diseases such as ovarian failure and cardiac fibrosis. However, relevant studies of MenSCs in ALI have not yet proceeded. We hypothesized that MenSC could attenuate the inflammation in lipopolysaccharide (LPS)-induced ALI and promote the repair of damaged lung. ALI model was induced by LPS in C57 mice, and saline or MenSCs were administered via tail vein after four hours...

PURPOSE OF REVIEW: The current review seeks to define ischemic hepatitis and its associated comorbidities. It means to review the pathophysiology, clinical presentation, clinical course, outcomes, and any potential therapies. RECENT FINDINGS: Ischemic hepatitis has long been associated with cardiovascular disease; recent reports have found a substantial link between preexisting cardiovascular disease and the risk for developing ischemic hepatitis. A proposed mechanism by which hepatic congestion predisposes the liver to hemodynamic injury further defines this link...

Patient respiratory motion during PET image acquisition leads to blurring in the reconstructed images and may cause significant artifacts, resulting in decreased lesion detectability, inaccurate standard uptake value calculation and incorrect treatment planning in radiation therapy. To reduce these effects data can be regrouped into (nearly) 'motion-free' gates prior to reconstruction by selecting the events with respect to the breathing phase. This gating procedure therefore needs a respiratory signal: on current scanners it is obtained from an external device, whereas with data driven (DD) methods it can be directly obtained from the raw PET data...

OBJECTIVES: PJP is a major cause of morbidity and mortality in immunocompromised individuals. Diagnosing PJP is often difficult because respiratory signs might be minimal or absent and the sensitivity of a chest X-ray (CXR) is low. We studied the clinical risk factors in order to increase awareness and facilitate the diagnosis. METHODS: We studied a prospective case series over a one year period (from 1 January 2015 to 1 January 2016) and did a retrospective analysis (from 2013 to 2016) of all PJP positive bronchoalveolar lavage (BAL) analysis...

Rasburicase is indicated for the prevention and treatment of tumor lysis syndrome which can be a potentially life-threatening emergency. The drug has oxidizing potential and as an adverse effect, it can convert the ferrous form of iron in erythrocytes to its ferric form resulting in the formation of methemoglobin which makes the heme component incapable of carrying oxygen. Patients with glucose-6-phosphate dehydrogenase enzyme deficiency are at high risk of methemoglobinemia from oxidizing agents. Symptoms of methemoglobinemia range from none to life-threatening hypoxemia, cyanosis and respiratory compromise...

Purpose There are limited data regarding the clinical use of decitabine for the treatment of acute myeloid leukemia in patients with a serum creatinine of 2 mg/dL or greater. Methods We retrospectively evaluated 111 patients with acute myeloid leukemia who had been treated with decitabine and compared the development of toxicities during cycle 1 in those with normal renal function (creatinine clearance greater than or equal to 60 mL/min) to those with renal dysfunction (creatinine clearance less than 60 mL/min)...

Many forms of interstitial lung disease (ILD) can progress to extensive fibrosis and respiratory failure. Idiopathic pulmonary fibrosis (IPF), which generally has a poor prognosis, has been thoroughly studied over the past two decades, and many important discoveries have been made that pertain to genetic predisposition, epidemiology, disease pathogenesis, diagnosis, and management. Additionally, non-IPF forms of ILD can have radiologic and histopathologic manifestations that mimic IPF, and making an accurate diagnosis is key to providing personalized medicine to patients with pulmonary fibrosis...

REVIEW
Tomi Tuomainen, Pasi Tavi
In mammalian heart, incessant production of cellular energy is vital for maintaining continuous mechanical pumping function providing the body for oxygen and nutrients. To ensure this essential function, cardiac muscle adapt to increased energy demand or compromised energy supply by reprogramming the network of genes whose products are necessary to match the production of energy to consumption. Failure in this regulation leads to severe cardiac dysfunction and has been associated with cardiac pathogenesis including cardiac hypertrophy, failure and diabetes...

BACKGROUND: Lactate has been recognised as a prognostic factor in several critical conditions. Veno-Venous Extracorporeal Membrane Oxygenation (VV-ECMO) is a well-established therapy in patients with Acute Respiratory Disease Syndrome (ARDS) unresponsive to conventional therapy and echocardiography pre ECMO initiation has been recently reported to help in risk stratifying these patients. METHODS: We assessed whether the detection of hyperlactataemia could be associated with the presence of left ventricle (LV) or right ventricle (RV) dysfunction in 121 consecutive patients with refractory ARDS...

INTRODUCTION: Severe acute respiratory distress syndrome (ARDS) has a high mortality, and there is limited knowledge about management of severe ARDS refractory to standard therapy. Early evidence suggests that therapeutic hypothermia (TH) could be a viable treatment for acute respiratory failure. We present 2 cases where TH was successfully used to manage refractory ARDS on extracorporeal membrane oxygenation (ECMO) and a review of the literature around TH and acute respiratory failure...

Traumatic brain injury (TBI) results in rapid reactive oxygen species (ROS) production and oxidative damage to essential brain cellular components leading to neuronal dysfunction and cell death. It is increasingly appreciated that a major player in TBI-induced oxidative damage is the reactive nitrogen species (RNS) peroxynitrite (PN) which is produced in large part in injured brain mitochondria. Once formed, PN decomposes into highly reactive free radicals that trigger membrane lipid peroxidation (LP) of polyunsaturated fatty acids (e...

REVIEW
Mamta Fuloria, Judy L Aschner
Failure of the normal circulatory adaptation to extrauterine life results in persistent pulmonary hypertension of the newborn (PPHN). Although this condition is most often secondary to parenchymal lung disease or lung hypoplasia, it may also be idiopathic. PPHN is characterized by elevated pulmonary vascular resistance with resultant right-to-left shunting of blood and hypoxemia. Although the preliminary diagnosis of PPHN is often based on differential cyanosis and labile hypoxemia, the diagnosis is confirmed by echocardiography...

BACKGROUND: The acquisition of intravenous access in the actively convulsing patient is difficult. This often delays the administration of the intravenous benzodiazepine necessary for seizure abortion. Delays in seizure abortion are associated with increased pharmacoresistance, increased risk of neuronal injury, worse patient outcomes and increased morbidity. OBJECTIVE: To assess whether the delay imposed by IV access acquisition is justified by improved outcomes...

BACKGROUND: Esophagectomy has been the standard of care for patients with intramucosal adenocarcinoma (IMC) in the setting of Barrett's esophagus. It is, however, associated with significant post-operative morbidity and mortality. Endoscopic mucosal resection (EMR) offers a minimally invasive approach with lesser morbidity. This study investigates the transition from esophagectomy to EMR for IMC with respect to eradication rates, post-operative morbidity, and long-term survival. METHODS: Patients diagnosed with IMC from 2005 to 2013 were identified retrospectively...

Acute respiratory compromise describes a deterioration in respiratory function with a high likelihood of rapid progression to respiratory failure and death. Identifying patients at risk for respiratory compromise coupled with monitoring of patients who have developed respiratory compromise might allow earlier interventions to prevent or mitigate further decompensation. The National Association for the Medical Direction of Respiratory Care (NAMDRC) organized a workshop meeting with representation from many national societies to address the unmet needs of respiratory compromise from a clinical practice perspective...

BACKGROUND: Ventricular assist devices (VADs) are alternative approaches to medical treatment in patients with acute or chronic heart failure. The goal of this study was to compare an anesthetic approach in patients undergoing implantation of a VAD with (on-pump) or without (off-pump) cardiopulmonary bypass (CPB) through left thoracotomy. METHODS: A total of 32 patients were divided into 2 groups: on-pump (group 1) and off-pump (group 2). A standard anesthesia protocol was used in all patients...

BACKGROUND: In France, referral centres in teaching hospitals were created 10 years ago to provide MD patients with treatments and follow-up designed to prevent complications and improve outcomes. Respiratory failure is a major cause of death among subjects with MD, and its prevention and treatment can serve as a touchstone for assessing the effectiveness of MD care pathways. OBJECTIVE: We report data from a preliminary study of admissions of MD patients in France and of factors associated with mortality, with special emphasis on respiratory failure [RF]...

Home noninvasive ventilation (NIV) is used in COPD patients with concomitant chronic hypercapnic respiratory failure in order to correct nocturnal hypoventilation and improve sleep quality, quality of life, and survival. Monitoring of home NIV is needed to assess the effectiveness of ventilation and adherence to therapy, resolve potential adverse effects, reinforce patient knowledge, provide maintenance of the equipment, and readjust the ventilator settings according to the changing condition of the patient...
