The treatment of pediatric high-risk neuroblastoma is intensive and multimodal. Despite the introduction of immunotherapy for minimal residual disease, survival rates remain suboptimal and new therapies are needed. As part of a phase 2 trial, we are using a consolidation therapy regimen which combines a busulfan/melphalan conditioning schema, autologous hematopoietic cell transplant (AHCT), and experimental immunotherapy with hu14.18K322A (a humanized anti-GD2 monoclonal antibody), GM-CSF, and IL-2, with or without the adoptive transfer of haploidentical natural killer cells (NKs)...

Multiple physiological systems interact throughout the development of a complex disease. Knowledge of the dynamics and connectivity of interactions across physiological systems could facilitate the prevention or mitigation of organ damage underlying complex diseases, many of which are currently refractory to available therapeutics (e.g., hypertension). We studied the regulatory interactions operating within and across organs throughout disease development by integrating in vivo analysis of gene expression dynamics with a reverse engineering approach to infer data-driven dynamic network models of multi-organ gene regulatory influences...

Trauma remains a tremendous medical burden partly because of increased expenditure for the management of multiple organ dysfunction syndrome (MODS) developed during hospital stay. The intestinal barrier injury continues to be a second insult resulting in MODS which currently lacks efficient strategies for prevention. Recent studies have uncovered multi-organ protective benefits of atrial natriuretic peptide (ANP) in cardiovascular disease. However, the role of ANP in prevention of MODS following severe trauma has not been understood...

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and is associated with the worldwide epidemics of obesity, diabetes and cardiovascular diseases. NAFLD ranges from benign fat accumulation in the liver (steatosis) to non-alcoholic steatohepatitis (NASH), and cirrhosis which can progress to hepatocellular carcinoma and liver failure. Mass spectrometry and magnetic resonance spectroscopy-coupled stable isotope-based flux studies provide new insights into the understanding of NAFLD pathogenesis and the disease progression...

Scorpion stings are common in tropical and subtropical regions. The history and clinical manifestation warrant urgent recognition and treatment. The incidence of scorpion stings in Pakistan is not known as there is no published data available in literature. We report our experience of a yellow scorpion sting victim who required intensive care admission after developing multi-organ dysfunction.

Previous studies have indicated that gut-derived endotoxin played a pivotal role for aggravating systemic inflammatory response to multi-organ dysfunction under heatstroke. Dexmedetomidine (DEX) could protect against inflammation and multi-organ injury in various scenarios. The aim of this study was to explore the protective effect of DEX on heatstroke and the mechanism involved. Male C57BL/6 mice were placed in a controlled climate chamber (40 ± 1°C) until the maximum core temperature (Tc, Max) of 42...

Direct cortical stimulation (DCS) is considered the gold-standard for functional cortical mapping during awake surgery for brain tumor resection. DCS is performed by stimulating one local cortical area at a time. We present a feasibility study using an intra-operative technique aimed at improving our ability to map brain functions which rely on activity in distributed cortical regions. Following standard DCS, Multi-Site Stimulation (MSS) was performed in 15 patients by applying simultaneous cortical stimulations at multiple locations...

Patients with cirrhosis who are awaiting liver transplantation are at high risk for development of critical illness. Current liver allocation policies which dictate a "sickest first" approach coupled with a mismatch between need and availability of organs results in longer wait times and thus, patients are becoming increasingly ill while awaiting organ transplantation. Even patients with well compensated cirrhosis may suffer acute deterioration, the syndrome of acute-on-chronic liver failure (ACLF) results in multi-system organ dysfunction and a marked increase in associated short-term morbidity and mortality...

Obstructive sleep apnea (OSA), the most severe form of sleep disordered breathing, is characterized by intermittent hypoxia during sleep (IH), sleep fragmentation, and episodic hypercapnia. OSA is associated with increased risk for morbidity and mortality affecting cardiovascular, metabolic, and neurocognitive systems, and more recently with non-alcoholic fatty liver disease (NAFLD) and cancer-related deaths. Substantial variability in OSA outcomes suggests that genetically-determined and environmental and lifestyle factors affect the phenotypic susceptibility to OSA...

Inborn defects of cholesterol biosynthesis are metabolic disorders presenting with multi-organ and tissue anomalies. An autosomal recessive defect involving the demethylating enzyme C4-methyl sterol (SC4MOL) has been reported in only 4 patients so far. In infancy, all patients were affected by microcephaly, bilateral congenital cataracts, growth delay, psoriasiform dermatitis, immune dysfunction, and intellectual disability. Herein, we describe a new case of SC4MOL deficiency in which a 19-year-old Italian male was affected by bilateral congenital cataracts, growth delay and learning disabilities, behavioral disorders and small stature, but not microcephaly...

The anaphylatoxins produced by an unbridled complement cascade in atypical hemolytic uremic syndrome (aHUS) can alter the leukocyte environment in tissues and peripheral blood, causing clinically significant eosinophilia. While the membrane attack complex and C5a anaphlatoxin can be suppressed with anti-C5 biologics, the production of C3a is still capable of driving a destructive hypereosinophilic syndrome in spite of anticomplement therapy. The side-effects of glucocorticoids in treating hypereosinophilic syndrome limit their therapeutic index in long-term treatment and this behooves the use of alternative strategies...

Iron is a 'one-way' element and the primary point of regulation of body iron stores is at the level of intestinal iron absorption. Repeated blood transfusions for congenital anaemias bypass this regulatory checkpoint and inevitably lead to iron overload in the long-term. Iron overload causes multi-organ dysfunction of the heart, liver, pancreas and joints. It also causes reproductive toxicity primarily through its damaging effect on the anterior pituitary leading to hypogonadotrophic hypogonadism. Another less understood mechanism of reproductive toxicity is direct gonadal damage of excess free iron...

The prevalence of non-alcoholic fatty liver disease (NAFLD) has sharply increased over the past several decades in Korea. In most cases of NAFLD, metabolic stress and cellular apoptosis are often driven by metabolic abnormality, eventually leading to inflammation and fibrosis . Along with a dramatic surge in the obesity epidemic, 10-20% of NAFLD patients ultimately progress to non-alcoholic steatohepatitis (NASH), a precursor to cirrhosis and hepatocellular carcinoma, as well as multi-organ systemic diseases...

BACKGROUND: Alström syndrome (AS) is a rare monogenetic disorder with multi-organ involvement. Complex metabolic disturbances are common and cardiomyopathy is a well-recognized feature in infants as well as in older children and adults. Although the mechanism of cardiomyopathy is not known, previous reports suggest that individuals with infantile-onset cardiac disease recover completely. METHODS: In this single center prospective series of 38 children and adults (age range 1...

Mitochondrial complex I (NADH: ubiquinone oxidoreductase; CI) is central to the electron transfer chain (ETC), oxidative phosphorylation, and ATP production in eukaryotes. CI is a multi-subunit complex with a complicated yet organized structure that optimally connects electron transfer with proton translocation and forms higher-order supercomplexes with other ETC complexes. Efforts to understand the molecular genetics, expression profile of subunits, and structure-function relationship of CI have increased over the years due to the direct role of the complex in human diseases...

We describe a young patient who ingested 18 g (240 times the daily therapeutic dose) of venlafaxine in a suicide attempt. She developed severe cardiomyopathy in a takotsubo distribution causing cardiogenic shock and multi-organ dysfunction syndrome (MODS). She was successfully treated with intravenous lipid emulsion (ILE), extracorporeal life support (ECLS) and CytoSorb®. This is remarkable as, to the best of the authors' knowledge, this is the highest amount of venlafaxine intake seen in the literature with a nonfatal outcome...
