Metastasis of lung carcinoma cells is a major cause of organ failure and mortality of patients with lung cancer. Lung mast cells are a type of immune cell which reside in the respiratory mucosa. High numbers of mast cells are associated with the majority of common types of cancer; however, the effects of mast cells on cancer remain unclear. In the present study, the effects of mast cell chymase (MCC) on the proliferation and adhesion of the lung carcinoma cell lines A549 and H520 was investigated. After 24 h of treatment, the highest dose of MCC (50 mU/ml) decreased the proliferation rate of A549 and H520 cells, whereas the lowest dose of MCC (5 mU/ml) resulted in a small increase in the viability...

The treatment of hepatitis C virus in monoinfected and HIV-coinfected patients has greatly changed over recent years as a result of the introduction of direct-acting antiviral agents (DAAs), which have revolutionized clinical outcomes and led to sustained virological response rates above 90-95%. The discovery of new molecules and the subsequent competition between pharmaceutical companies, together with the negotiated price policies pursued by many national health systems, have led to a gradual reduction in the cost of DAAs, and expand their use to an increasing number of patients, including those with mild liver damage...

Pompe disease is an extra-rare metabolic storage disease with deficiency of acid-alpha-glucosidase (GAA) enzyme activity, which leads to the pathologic accumulation of glycogen in target tissues (skeletal muscles, heart, brain). Clinical features and severity vary by the age of onset, rate of extent of organ involvement. In the late-onset Pompe disease (LOPD) form, essential cardiomyopathy seems to be uncommon. Muscles weakness and respiratory failure are the main symptoms of adult patient with Pompe disease...

The risk of cardiac or lung failure after liver transplantation (LT) is significant. In rare cases, the usual intensive care techniques fail to maintain organ oxygenation with a risk of multiorgan dysfunction. Although extracorporeal membrane oxygenation (ECMO) is a difficult and risky procedure, it can be proposed as life-saving. Four children with either acute pulmonary (three) or cardiac (one) failure after LT, and the criteria that decided the use of ECMO (level of ventilation and results, dosage of inotropic drugs, cardiac ultrasound, blood lactate) were retrospectively reported...

Chronic graft-versus-host disease (cGVHD) is a serious complication of allogeneic stem cell transplantation with few effective options available after failure of corticosteroids. B and T cells play a role in the pathophysiology of cGVHD. Ibrutinib inhibits Bruton's tyrosine kinase in B cells and interleukin-2-inducible T-cell kinase in T cells. In preclinical models, ibrutinib reduced severity of cGVHD. This multicenter, open-label study evaluated the safety and efficacy of ibrutinib in patients with active cGVHD with inadequate response to corticosteroid-containing therapies...

Cardiogenic shock is a high-acuity, potentially complex, and hemodynamically diverse state of end-organ hypoperfusion that is frequently associated with multisystem organ failure. Despite improving survival in recent years, patient morbidity and mortality remain high, and there are few evidence-based therapeutic interventions known to clearly improve patient outcomes. This scientific statement on cardiogenic shock summarizes the epidemiology, pathophysiology, causes, and outcomes of cardiogenic shock; reviews contemporary best medical, surgical, mechanical circulatory support, and palliative care practices; advocates for the development of regionalized systems of care; and outlines future research priorities...

Eating disorders are not commonly diagnosed in individuals aged >50 years, yet they are associated with significant psychiatric comorbidities and overall morbidity. Anorexia nervosa is the most common eating disorder among this age group, and women are affected most often. We present the fatal case of a 66-year old woman with severe malnutrition and newly diagnosed anorexia nervosa. Inpatient refeeding was unsuccessful, and she succumbed to multisystem organ failure. The timely recognition of eating disorders among older people is important for family physicians who care for patients across the life spectrum...

BACKGROUND: According to the new definition of septic shock, vasopressor therapy and hyperlactatemia are essential for diagnosis. However, there is controversy regarding the cutoff value for lactate, and prognostic factors in patients with septic shock and hypolactatemia. This study evaluated the prognostic significance of the cutoff value for lactate level in septic shock patients. METHODS: The retrospective observational cohort study enrolled 1043 patients aged ≥18 years who meet the revised definition of septic shock...

Severe falciparum malaria is associated with multiple organ dysfunction and a high rate of fatal outcome. Malaria is a world-wide disease in tropical areas through the bites of vector mosquitoes. Parasitic protozoans introduced by the mosquito's saliva to the blood travel to the liver then mature and reproduce. In humans, malaria is caused by Plasmodium falciparum, P. malariae, P. ovale, P. vivax, and P. knowlesi, and P. falciparum causes most deaths. Typical malaria symptoms include fever, chills, fatigue, headache, nausea, and vomiting...

Søren Møller, Flemming Bendtsen
Patients with cirrhosis and portal hypertension often develop complications from a variety of organ systems leading to a multiple organ failure. The combination of liver failure and portal hypertension result in a hyperdynamic circulatory state partly owing to simultaneous splanchnic and peripheral arterial vasodilatation. Increases in circulatory vasodilators are believed to be due to portosystemic shunting and bacterial translocation leading to redistribution of the blood volume with central hypovolemia. Portal hypertension per se and increased splanchnic blood flow are mainly responsible for the development and perpetuation of the hyperdynamic circulation and the associated changes in cardiovascular function with development of cirrhotic cardiomyopathy, autonomic dysfunction, and renal dysfunction as part of a cardiorenal syndrome...

PURPOSE: Estimating the biodistribution and the pharmacokinetics from timesequence SPECT images on a per-voxel basis is useful for studying activity nonuniformity or computing absorbed dose distributions by convolution of voxel kernels or Monte-Carlo radiation transport. Current approaches are either region-based, thus assuming uniform activity within the region, or voxel-based but using the same fitting model for all voxels. METHODS: We propose a voxel-based multi-model fitting method (VoMM) that estimates a fitting function for each voxel by automatically selecting the most appropriate model among a predetermined set with Akaike criteria...

INTRODUCTION AND HYPOTHESIS: The aim of this study was to compare outcomes after uterosacral ligament suspension (USLS) or sacrocolpopexy for symptomatic stage IV apical pelvic organ prolapse (POP) and evaluate predictors of prolapse recurrence. METHODS: The medical records of patients managed surgically for stage IV apical POP from January 2002 to June 2012 were reviewed. A follow-up survey was sent to these patients. The primary outcome, prolapse recurrence, was defined as recurrence of prolapse symptoms measured by validated questionnaire or surgical retreatment...

Infections and infectious complications are the major cause of morbidity and mortality in febrile neutropenic patients after autologous stem cell transplantation. Laboratory biomarkers are helpful for early identification of critically ill patients and optimal therapy management. Several studies in adult non-neutropenic patients proposed sTREM-1 as a superior biomarker for identification of septic patients as well as a predictor for survival in these patients compared with procalcitonin (PCT), C-reactive protein (CRP), or interleukin-8 (IL-8)...

Trauma and related sequelae result in disturbance of homeostatic mechanisms frequently leading to cellular dysfunction and ultimately organ and system failure. Regardless of the type and severity of injury, gender dimorphism in outcomes following trauma have been reported, with females having lower mortality than males, suggesting that sex steroid hormones (SSH) play an important role in the response of body systems to trauma. In addition, several clinical and experimental studies have demonstrated the effects of SSH on the clinical course and outcomes following injury...

Midkine (MDK) is a heparin-binding growth factor that is normally expressed in mid-gestational development mediating mesenchymal and epithelial interactions. As organisms age, expression of MDK diminishes; however, in adults, MDK expression is associated with acute and chronic pathologic conditions such as myocardial infarction and heart failure (HF). The role of MDK is not clear in cardiovascular disease and currently there is no consensus if it plays a beneficial or detrimental role in HF. The lack of clarity in the literature is exacerbated by differing roles that circulating and myocardial MDK play in signaling pathways in cardiomyocytes (some of which have yet to be elucidated)...

The core planar polarity pathway coordinates epithelial cell polarity during animal development, and loss of its activity gives rise to a range of defects, from aberrant morphogenetic cell movements to failure to correctly orient structures, such as hairs and cilia. The core pathway functions via a mechanism involving segregation of its protein components to opposite cells ends, where they form asymmetric intracellular complexes that couple cell-cell polarity. This segregation is a self-organizing process driven by feedback interactions between the core proteins themselves...

Acute-on-chronic liver failure (ACLF) is a clinical syndrome characterized by acute decompensation of liver cirrhosis, organ failure and high short-term mortality (20-80% at one month). The main precipitants are infections and excessive alcohol intake, and the mechanistic features include a high level of systemic inflammation, macrophage activation and liver injury. The severity of ACLF is graded according to the number and extent of organ failures. Prognostic scores help predict mortality and support decisions on intensive treatment or futility...
