The objective of this study was to investigate the factors that influence calf health and survival in Charolais cattle. Data from 2,740 calves, originating from 16 French farms and observed from birth until 30 d of age, were analyzed using models that took account of direct genetic, maternal genetic and common environmental effects. Both direct and maternal genetic parameters were estimated for birth weight (BW), calving ease (CE), neonatal vitality (NV), survival at 30 d (Surv), and umbilical infection and diarrhea at different ages (0-5 d: Umb1 and Diar1; 6-20 d: Umb2 and Diar2; and 21-30 d: Umb3 and Diar3)...

The long-lasting effects of early stress on brain development have been well studied. Recent evidence indicates that males and females respond differently to the same stressor. We examined the chronic effects of daily maternal separation (MS) on behavior and cerebral morphology in both male and female rats. Cognitive and anxiety-like behaviors were evaluated, and neuroplastic changes in 2 subregions of the prefrontal cortex (dorsal agranular insular cortex [AID] and cingulate cortex [Cg3]) and hippocampus (CA1 and dentate gyrus) were measured in adult male and female rats...

Vitamin K deficiency within neonates can result in vitamin K deficiency bleeding. Ensuring that newborns receive vitamin K is particularly critical in places where access to health care and blood products and transfusions is limited. The World Health Organization recommends that newborns receive a 1 mg intramuscular injection of vitamin K at birth. Evidence from multiple surveillance studies shows that the introduction of vitamin K prophylaxis reduces the incidence of vitamin K deficiency bleeding. Despite these recommendations, coverage of vitamin K prophylactic treatment in low-resource settings is limited...

The recognition of a pattern of steatotic liver injury where histology mimicked alcoholic liver disease but alcohol consumption was denied, led to the identification of non-alcoholic fatty liver disease (NAFLD). Non-alcoholic fatty liver disease has since become the most common chronic liver disease in adults owing to the global epidemic of obesity. However, in pediatrics, the term NAFLD seems incongruous: alcohol consumption is largely not a factor and inherited metabolic disorders (IMD) can mimic or co-exist with a diagnosis of NAFLD...

Coxsackievirus A10 (CVA10) has emerged worldwide as one of the main pathogens of hand, foot, and mouth disease (HFMD) in recent years. However, there is currently no commercial vaccine available to prevent CVA10 infection. Here we report the development of a recombinant virus-like particle (VLP) based candidate vaccine for CVA10. Co-expression of the capsid protein precursor P1 and the protease 3CD of CVA10 in Pichia pastoris resulted in cleavage of P1 into three capsid subunit proteins VP0, VP1, and VP3. These three subunit proteins co-assembled into CVA10 VLPs, which were visualized as spherical particles with a diameter of ∼30 nm under electron microscope...

Citrus fruits contain various types of flavonoids with powerful anti-aging and photoprotective effects on the skin, and have thus been attracting attention as potential, efficacious skincare agents. Here, we aimed to investigate the chemical composition of Citrus unshiu and its protective effects on photoaging. We isolated and identified a bioactive compound, 3,5,6,7,8,3',4'-heptamethoxyflavone (HMF), from C. unshiu peels using ethanol extraction and hexane fractionation. HMF inhibited collagenase activity and increased type I procollagen content in UV-induced human dermal fibroblast neonatal (HDFn) cells...

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)...

When any fetal blood group factor inherited from the father is not possessed by the mother, antepartum or intrapartum fetal-maternal bleeding may stimulate an immune reaction in the mother. Maternal immune reactions also can occur from blood product transfusion. The formation of maternal antibodies, or "alloimmunization," may lead to various degrees of transplacental passage of these antibodies into the fetal circulation. Depending on the degree of antigenicity and the amount and type of antibodies involved, this transplacental passage may lead to hemolytic disease in the fetus and neonate...

INTRODUCTION: The vertical transumbilical incision (TU) technique during neonatal abdominal exploration involves dissection and ligation of umbilical vessels, which allow access to all quadrants of the abdomen and complete bowel evisceration with minimal violation to the anterior abdominal wall. We compared patient characteristics and outcomes for neonates undergoing TU with standard transverse exploration. MATERIALS AND METHODS: A single-center retrospective review of neonates who underwent abdominal exploration between January 2010 and September 2015 was conducted after obtaining Institutional Review Board approval...

Essential generalized telangiectasia as the result of postcapillary venule dilatation, is characterized by the sudden development of generalized telangiectasias, sometimes involving the conjunctiva. A few pediatric cases have been reported. The main condition in the differential diagnosis includes syndromes with telangiectasia such as hereditary hemorrhagic telangiectasia of Rendu-Osler, unilateral nevoid telangiectasia, and neonatal lupus erythematous. We present an 11-month-old boy that presented because of telangiectasia located on the face and neck...

OBJECTIVES: Although routine catheter tip cultures are not recommended, previous reports have indicated that some cases of colonization, such as with S. aureus, can lead to subsequent bacteremia. To evaluate the safety of colonized cases without antimicrobial treatment, as well as the effectiveness of routine catheter tip cultures in the neonatal intensive care unit (NICU), we performed a retrospective data analysis in a Japanese community hospital. METHODS: We reviewed all peripherally inserted central venous catheter tip culture results from the NICU ward between April 2012 and June 2017 to determine whether they had antimicrobial treatments or subsequent infections...

OBJECTIVE: The majority of patients with chronic or gestational hypertension do not develop pre-eclampsia. Home blood-pressure monitoring (HBPM) has the potential to offer a more accurate and acceptable means of monitoring hypertensive patients during pregnancy compared with traditional pathways of frequent outpatient monitoring. The aim of this study was to determine whether HBPM reduces visits to antenatal services and is safe in pregnancy. METHODS: This was a case-control study of 166 hypertensive pregnant women, which took place at St George's Hospital, University of London...

OBJECTIVE: We recently found in a randomized clinical trial (ProTWIN) that cervical pessary prevented preterm birth and improved neonatal outcome in women with a multiple pregnancy and a cervical length (CL) <38mm. In this follow-up study we evaluated long-term developmental outcomes in the offspring of these women at three years corrected age. METHODS: We conducted a follow-up study of the ProTWIN trial, a trial in which between 2009 and 2012 asymptomatic women with a multiple pregnancy had been randomized to pessary or no pessary...

There is increasing evidence from pre-clinical and human studies that nutrition in the late fetal and early neonatal period has a significant impact on neurodevelopment across the lifespan. Certain nutrients have particularly large effects in this time period, and their deficits cause greater long-term risk. The mechanisms by which nutrients influence early brain growth and the sensitive periods for when certain nutrients should be provided are being elucidated. Assessments of nutritional status that index brain growth and predict long-term development are important to assess the efficacy of early life nutritional therapies...

AIM: Paediatric donation is a unique and extremely sensitive process that requires specific knowledge and competencies. Most countries use protocols for organ and tissue donation to ensure optimal care for the donor and family, but these mainly focus on adults. However, the donation process for children differs from adults in many ways. An overview of the literature was performed to identify protocols for the paediatric population. METHODS: PubMed, Web of Science, Embase and the Internet were searched up to March 2016 for papers or other sources in English related to specific organ and tissue donation protocols for children and neonates...

AIM: To systematically review the predictive validity of spontaneous early infant movements for later cerebral palsy (CP). METHOD: Cohort studies with published data to calculate predictive validity of early spontaneous movements for later CP were searched in four electronic databases: CINAHL, Embase, MEDLINE, and PsycINFO. RESULTS: Forty-seven studies met inclusion criteria. The Prechtl General Movements Assessment (GMA) during the fidgety period (10-20wks corrected age) had the strongest sensitivity: 97 per cent (95% confidence interval [CI] 93-99) and specificity: 89% (95% CI 83-93)...
