A day-old neonate presented with bowel obstruction and an abdominal mass. Exploratory laparotomy revealed complete tubular midgut duplication from duodeno-jejunal junction up to terminal ileum which was communicating with the ileum distally. At the proximal end, another 5×5 cm duplication cyst was identified and excised. Postoperatively, complaints were relieved. During follow-up, 99m-Tc-pertechnetate-SPECT scan showed ectopic gastric mucosa in lower abdomen and in the right hemithorax. CECT-chest showed a 3×3 cm foregut duplication cyst, but there were no respiratory symptoms...

The use of cardiovascular progenitor cells (CPCs) to repair damaged myocardium has been the focus of intense research. Previous reports have shown that pretreatments, including hypoxia, improve cell function. However, the age-dependent effects of short-term hypoxia on CPCs, and the role of signaling in these effects, are unknown. Cloned neonatal and adult CPCs expressing Isl1, c-Kit, KDR, PDGFRA, and CXCR4, were preconditioned using hypoxia (1% O2 for six hours). Intracellular signaling pathway changes were modeled using Ingenuity Pathway Analysis (IPA), while qRT-PCR, flow cytometry, and immunoblotting were used to measure pathway activation...

Nonpolio enteroviruses and parechoviruses are frequent causes of neonatal infection. Clinical manifestations of infection range from asymptomatic infection to mild infection without sequelae to septic shock with muiltiorgan failure. Neonates with clinically apparent infection typically have mothers and/or other contacts with recent symptoms consistent with a viral illness. Severe neonatal infection with nonpolio enterovirus or parechovirus cannot be differentiated clinically from serious bacterial infection...

Bilateral adrenal hemorrhages rarely occur during the neonatal period and are often associated with traumatic vaginal deliveries. However, the adrenal gland has highly regenerative capabilities and adrenal insufficiency typically resolves over time. We evaluated a newborn female after experiencing fetal macrosomia and a traumatic vaginal delivery. She developed acidosis and acute renal injury. Large adrenal hemorrhages were noted bilaterally on ultrasound, and she was diagnosed with adrenal insufficiency based on characteristic electrolyte changes and a low cortisol (4...

Preterm infants have increased risk of neonatal sepsis, potentially inducing brain injury, and they may benefit from early initiation of enteral milk feeding. Using preterm pigs as models, we hypothesized that early provision of bovine colostrum to parentally nourished newborns protects against sepsis and neuroinflammation during bloodstream infection. Preterm newborn pigs were administered 10 CFU/kg of intra-arterial Staphylococcus epidermidis (SE, an opportunistic pathogen often causing sepsis in preterm infants), followed by administration of total parenteral nutrition (TPN, SE + TPN, n = 15) or oral provision of bovine colostrum with supplementary parenteral nutrition (SE + COL, n = 14), and compared with uninfected, TPN-nourished controls (CON + TPN, n = 11)...

The aim of the current study was to elucidate whether inhibition of corticosterone (CORT) synthesis could modify stress response to feed deprivation and its possible interactions with feed restriction in the neonatal period in broiler chickens. Equal numbers of broiler chicks were subjected to either 60% feed restriction (60FR) or ad libitum (AL) on d 4, 5, and 6. On day 7, blood CORT, acute phase proteins (APP), interleukin-6 (IL-6) levels, and brain heat shock protein 70 (HSP70) expression were determined...

Molecular chaperone proteins perform a diversity of roles inside and outside the cell. One of the most important is the stabilization of misfolding proteins to prevent their aggregation, a process that is potentially detrimental to cell viability. Diseases such as Alzheimer's, Parkinson's, and cataract are characterized by the accumulation of protein aggregates. In vivo, many proteins are metastable and therefore under mild destabilizing conditions have an inherent tendency to misfold, aggregate, and hence lose functionality...

BACKGROUND: The goal of this study was to explore the association between neonatal infection and outcomes in children with cerebral palsy. METHODS: We conducted a retrospective cohort study using the Canadian CP Registry. Neonatal infection was defined as meeting one of the following criteria: (1) septicemia, (2) septic shock, or (3) administration of antibiotics for ≥10 days. Phenotypic profiles of children with cerebral palsy with and without an antecedent neonatal infection were compared...

In mammals, environmental factors including cold stress exert dramatic effects on adult health during late gestation, the cold stress response refers to an organism's response to cold. Indeed, cells and organs, including the hippocampus, are coordinated to respond to prevent hypothermia. The hippocampus act as an important brain structure that regulates the activity of the hypothalamic-pituitary-adrenal (HPA) axis, and suppress the stress reaction through feedback regulation of the HPA axis. To evaluate the response of the hippocampus during prenatal cold stress, we established a prenatal cold stress rat model...

BACKGROUND: There is a lack of consensus on the timing of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) liberation. VA-ECMO weaning usually consists of serial decrements until an idling flow is achieved, supported by echocardiographic and haemodynamic assessments. Even with minimal idling flow, right ventricular (RV) preload is reduced and, hence, right heart function is not fully tested under adequate loading conditions. Following the use of a novel technique called Pump Controlled Retrograde Trial Off (PCRTO) in neonate VA-ECMO weaning, we report the use of this technique in seven adult patients on VA-ECMO...

Shock in newborn infants has unique etiopathologic origins that require careful assessment to direct specific interventions. Early diagnosis is key to successful management. Unlike adults and pediatric patients, shock in newborn infants is often recognized in the uncompensated phase by the presence of hypotension, which may be too late. The routine methods of evaluation used in the adult and pediatric population are often invasive and less feasible. We aim to discuss the pathophysiology in shock in newborn infants, including the transitional changes at birth and unique features that contribute to the challenges in early identification...

Oxidative stress and reactive oxygen species generation have been implicated in the pathogenesis of several neurological disorders including Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis and multiple sclerosis. In the present study, the neuroprotective effects of selegiline against hydrogen peroxide-induced oxidative stress in hippocampus-derived neural stem cells (NSCs) were evaluated. NSCs isolated from neonatal Wistar rats were pretreated with different doses of selegiline for 48 h and then exposed to 125 µM H2O2 for 30 min...

Prenatal cold stress is one of the earliest factors affecting mammalian health, and is associated with neonatal growth retardation and immune dysfunction, thus increasing disease susceptibility. The mechanisms underlying these observations remain unclear; hence, the objective of this study was to elucidate placental responses to cold stress. 60 maternal rats were randomly allocated to either stressed (n = 30) or non-stressed (control, n = 30) treatment conditions and 30 pubs (n=15) were used for the pups analysis...

OBJECTIVE: There are no large studies evaluating pulmonary haemorrhage (PH) in premature infants. We sought to quantify the clinical characteristics, morbidities and mortality associated with early PH. DESIGN: Data were abstracted from the Pediatrix Clinical Data Warehouse, a large de-identified data set. For incidence calculations, we included infants from 340 Pediatrix United States Neonatal Intensive Care Units from 2005 to 2014 without congenital anomalies. Infants <28 weeks' gestation with PH within 7 days of birth were then matched with two controls for birth weight, gestational age, gender, antenatal steroid exposure, day of life 0 or 1 intubation and multiple gestation...

INTRODUCTION: The clinical syndrome of neonatal sepsis, comprising signs of infection, septic shock and organ dysfunction in infants ≤4 weeks of age, is a frequent sequel to bloodstream infection and mandates urgent antimicrobial therapy. Bacterial characterisation and antimicrobial susceptibility testing is vital for ensuring appropriate therapy, as high rates of antimicrobial resistance (AMR), especially in low-income and middle-income countries, may adversely affect outcome. Ho Chi Minh City (HCMC) in Vietnam is a rapidly expanding city in Southeast Asia with a current population of almost 8 million...

OBJECTIVE: To evaluate the value of blood lactic acid (BLA) as a predictor for the severity and prognosis of neonatal shock. METHODS: A total of 326 neonates with shock were enrolled and divided into three groups based on the severity, namely mild group (n=147), moderate group (n=105), and severe group (n=74). BLA level was measured during and early after (about 6 hours later) fluid resuscitation, and lactate clearance rate (LCR) was calculated. The receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of BLA in neonatal shock...

Food allergies manifest in a variety of clinical conditions within the gastrointestinal tract, skin and lungs, with the most dramatic and sometimes fatal manifestation being anaphylactic shock. Major progress has been made in basic, translational and clinical research, leading to a better understanding of the underlying immunological mechanisms that lead to the breakdown of clinical and immunological tolerance against food antigens, which can result in either immunoglobulin E (IgE)-mediated reactions or non-IgE-mediated reactions...
