#1
Alican Nalci, Bhaskar D Rao, Thomas T Liu
In resting-state functional MRI (rsfMRI), the correlation between blood oxygenation level dependent (BOLD) signals across different brain regions is used to estimate the functional connectivity of the brain. This approach has led to the identification of a number of resting-state networks, including the default mode network (DMN) and the task positive network (TPN). Global signal regression (GSR) is a widely used pre-processing step in rsfMRI that has been shown to improve the spatial specificity of the estimated resting-state networks...

BACKGROUND: Once it is established that a jaundiced infant has direct hyperbilirubinemia, the principal diagnostic concern is to differentiate hepatocellular from obstructive cholestasis. Traditional tests such as ultrasonography, percutaneous liver biopsy and technetium 99 m hepatobiliary iminodiacetic acid (HIDA) scan are often not sufficiently discriminating. Definitive exclusion of biliary atresia (BA) in the infant with cholestatic jaundice usually requires mini-laparotomy and intra-operative cholangiography...

Total parenteral nutrition (TPN) can be a lifesaving intervention for premature neonates and it is often delivered through peripheral access in this unique population. However, extravasation and tissue damage can result. Current literature lacks strong evidence regarding the treatment and reconstruction of such injuries in this age group. The authors present a patient with a 30-week gestational age premature newborn whom suffered an extravasation injury with peripherally administered TPN leading to full thickness skin and soft tissue necrosis of the dorsum of the right hand...

INTRODUCTION: Gastroschisis (GS) is a common abdominal wall defect necessitating neonatal surgery and intensive care. We hypothesized that inborn patients had improved outcomes compared to patients born at an outside hospital (outborn) and transferred for definitive treatment. METHODS: A single center, retrospective chart review at a pediatric tertiary care center was performed from 2010 to 2015. All patients whose primary surgical treatment of GS was performed at this center were included...

In 1968, Wilmore and Dudrick reported an infant sustained by parenteral nutrition (PN) providing a potential for survival for children with significant intestinal resections. Increasing usage of TPN over time led to some patients developing Intestinal Failure Associated Liver Disease (IFALD), a leading cause of death and indication for liver/intestinal transplant. Over time, multi-disciplinary teams called Intestinal Rehabilitation Programs (IRPs) began providing meticulous and innovative management. Usage of alternative lipid emulsions and lipid minimization strategies have resulted in the decline of IFALD and an increase in long-term and transplant-free survival, even in the setting of ultrashort bowel (< 20 cm)...

Gastrointestinal tract is one of the major systems affected by graft-versus-host disease (GVHD). Injury to the gut during conditioning therapy before stem-cell transplantation (SCT) plays a pivotal role in the initiation of inflammatory stimuli. We reviewed medical records of the patients who underwent SCT between April 2010 and June 2013 in our center. A stepwise upgrade diet was given to the children with acute GI-GVHD (Gastrointestinal GVHD) including parenteral and enteral nutrition. A total of 105 patients underwent SCT and seven patients developed grade III-IV acute GI-GVHD...

BACKGROUND: Conventional laparoscopy (CL) using 3-5 mm ports has become the goldstandard for pediatric nephrectomy (N), heminephrectomy (HN) and heminephrecto-ureterectomy (HNU) for many years now. Recently the spectrum of minimal invasive surgery (MIS) has been extended by variants like laparoendoscopic single-site surgery (LESS) or robot-assisted surgery (RAS). However such technical developments tend to drive surgical euphoria and feasibility studies, but may miss adequate academic research about function and proven patients' benefits...

Enterocutaneous fistulas (ECF) are a difficult and costly surgical complication to manage. The standard treatment of nil per os (NPO) and total paraenteral nutrition (TPN) is not well tolerated by patients. TPN is also known for complications associated with long term central venous catheterization and for high cost of prolonged hospital stay. We present two low output ECF cases successfully treated with viable cryopreserved placental membrane (vCPM) placed into the fistula tracts. One patient is a 59-year-old male with a low output ECF from a jejunostomy tube site four weeks after the surgery...

BACKGROUND/PURPOSE: Total parenteral nutrition (TPN) has been reported to be associated with mucosal atrophy of the small intestine. Ghrelin has hormonal, orexigenic, and metabolic activities. We investigated whether ghrelin improved intestinal mucosal atrophy using a TPN-supported rat model. METHODS: Rats underwent jugular vein catheterization and were divided into four groups: TPN alone (TPN), TPN plus low-dose ghrelin (TPNLG), TPN plus high-dose ghrelin (TPNHG), and oral feeding with normal chow (OF)...

OBJECTIVES: Total parenteral nutrition (TPN) presumably benefits cancer patients although reports have disputed the significance of this nutritional intervention. We sought to compare the postoperative outcomes of ovarian cancer patients treated with either TPN or conservative management. METHODS: We retrospectively evaluated the impact of TPN and conservative management in ovarian cancer patients who underwent debulking surgery and a bowel resection. The primary study variables encompassed patient time until restoration of bowel function, number of postoperative complications and duration of hospital stay...

When encoding a real-life, continuous stimulus, the same neural circuits support processing and integration of prior as well as new incoming information. This ongoing interplay is modulated by attention, and is evident in regions such as the prefrontal cortex section of the task positive network (TPN), and in the posterior cingulate cortex (PCC), a hub of the default mode network (DMN). Yet the exact nature of such modulation is still unclear. To investigate this issue, we utilized an fMRI task that employed movies as the encoded stimuli and manipulated attentional load via an easy or hard secondary task that was performed simultaneously with encoding...

Manganese (Mn) is an essential heavy metal. However, Mn's nutritional aspects are paralleled by its role as a neurotoxicant upon excessive exposure. In this review, we covered recent advances in identifying mechanisms of Mn uptake and its molecular actions in the brain as well as promising neuroprotective strategies. The authors focused on reporting findings regarding Mn transport mechanisms, Mn effects on cholinergic system, behavioral alterations induced by Mn exposure and studies of neuroprotective strategies against Mn intoxication...

BACKGROUND: The principal cause of iron overload in patients with haematological malignancies is recurrent red cell transfusions for anaemia. The serum ferritin level reflects the iron burden in the body, in the absence of inflammation or liver disease. In Malaysia, data are lacking on the association between pre-transplant serum ferritin levels and outcome after allogeneic haemopoietic stem cell transplant. METHODS: We did a cross-sectional study using retrospective data of 106 post-allogeneic haemopoietic stem cell transplant patients (HLA-matched sibling) with haematological malignancies at Hospital Ampang to determine the relationship between pre-transplant serum ferritin levels and post-transplant outcome, post-transplant complications and survival time...
