Regarding PAF morphology, both systems provided adequate preservation, with values higher than 70% normal follicles observed before and after culture. The TUNEL assay revealed that both SSV (52.39%) and OTC (41.67%) could preserve DNA integrity after vitrification and after 24 h of culture. In summary, both open and closed systems were equally efficient in preserving agouti ovarian tissues, especially concerning the preantral follicle morphology and DNA integrity; however, the OTC seems to provide a less adequate environment for bacterial proliferation.
Accumulating evidence suggests neurological manifestations after dengue infection. However, the relationship between dengue and long-term neurocognitive sequel remains unclear.
We recruited 816 patients with dengue and 8,160 controls between 1997 and 2012 using data from Taiwan National Health Insurance Research Database and followed them up until the end of 2013. Individuals who exhibited any type of dementia were identified during the follow-up period. Cox regression analyses were performed with adjustments for demographic data and medical and mental comorbidities (cerebrovascular diseases, traumatic brain injury, hypertension, dyslipidemia, diabetes mellitus, depression, alcohol use disorder, and substance use disorder). The E-value for the causality of the evidence was calculated. Sensitivity analysis was conducted to exclude patients with prodromal dementia.
Patients with dengue were more likely to develop dementia (hazard ratio [HR] 2.23, 95% confidence interval [CI] 1.51-3.28), Alzheimer's disease (HR 3.03, 95% CI 1.08-8.45), and unspecified dementia (HR 2.25, 95% CI 1.43-3.53), but not vascular dementia compared to controls during the follow-up period. Sensitivity analyses after exclusion of the observation period over the first three years or first five years and after exclusion of patients' enrollment before 2010 or 2008 showed consistent findings. The E-values for the HR (range 3.62-5.51) supported the association between dengue and subsequent dementia among the whole population, men, and women.
The risk of dementia was 2.23-fold higher in patients diagnosed with dengue during the follow-up period than in the controls. Further studies are necessary to investigate the underlying pathophysiology of dengue and dementia.

Several factors can influence eating behavior and drive food consumption in excess of energy requirements for homeostasis. It is well established that stress and negative affect contribute to the aetiology of eating disorders and weight gain, and there is substantial evidence suggesting sex differences in sub-clinical and clinical types of overeating. This review will examine how negative affect and stress shape eating behaviors, and how the relationship between the physiological, endocrine, and neural responses to stress and eating behaviors differs between men and women. We will examine several drivers of overeating and explore possible mechanisms underlying sex differences in eating behavior.
EEG and fMRI have contributed greatly to our understanding of brain activity and its link to behaviors by helping to identify both when and where the activity occurs. This is particularly important in the development of brain-computer interfaces (BCIs), where feed forward systems gather data from imagined brain activity and then send that information to an effector. The purpose of this study was to develop and evaluate a computational approach that enables an accurate mapping of spatial brain activity (fMRI) in relation to the temporal receptors (EEG electrodes) associated with imagined lower limb movement.
EEG and fMRI data from 16 healthy, male participants while imagining lower limb movement were used for this purpose. A combined analysis of fMRI data and EEG electrode locations was developed to identify EEG electrodes with a high likelihood of capturing imagined lower limb movement originating from various clusters of brain activity. This novel feature selection tool was used to develop an artificial neural network model to classify right and left lower limb movement.
Results showed that left versus right lower limb imagined movement could be classified with 66.5% accuracy using this approach. Comparison with existing methods Adopting a purely data-driven approach for feature selection to use in the right/left classification task resulted in the same accuracy (66.6%) but with reduced interpretability.
The developed fMRI-informed EEG approach could pave the way towards improved brain computer interfaces for lower limb movement while also being applicable to other systems where fMRI could be helpful to inform EEG acquisition and processing.

To compare the term equivalent) brain MRI findings between erythropoietin (Epo) treated and placebo control groups in infants 24-0/7 to 27-6/7 weeks' gestational age (GA) and to assess the associations between MRI findings and neurodevelopmental outcomes at 2 years corrected age (CA).
The association between brain abnormality scores and Bayley Scales of Infant Development (BSID-III) at 2 years CA was explored in a subset of infants enrolled in the Preterm Erythropoietin Neuroprotection Trial. Potential risk factors for neurodevelopmental outcomes such as treatment assignment, recruitment site, GA, inpatient complications and treatments were examined using Generalized Estimating Equation models.
110 infants were assigned to Epo and 110 to placebo groups. 27% of MRI scans were rated as normal, and 60%, 10% and 2% were rated as having mild, moderate, or severe abnormality. Brain abnormality scores did not significantly differ between the treatment groups. Factors that increased the risk of higher brain injury scores included intubation; bronchopulmonary dysplasia; retinopathy of prematurity; opioid, benzodiazepine, or antibiotic treatment >7 days; and periventricular leukomalacia or severe intraventricular hemorrhage diagnosed on cranial ultrasound. see more Increased global brain abnormality and white matter injury scores at TE were associated with reductions in cognitive, motor, and language abilities at 2 years CA.
Evidence of brain injury on brain MRIs obtained at TE correlated with adverse neurodevelopmental outcomes as assessed by the BSID-III at 2 years CA. Early Epo treatment had no effect on the MRI brain injury scores compared with the placebo group.

To evaluate the prevalence and clinical significance of autoantibodies in children with overweight and obesity with non-alcoholic fatty liver (NAFL), and non-alcoholic steatohepatitis (NASH) in comparison with those with autoimmune liver disease (ALD).
This is a retrospective, cross-sectional study in 2007-2016, of children with a biopsy proven diagnosis of NAFL, NASH, autoimmune hepatitis (AIH), or primary sclerosing cholangitis (PSC), and a body mass index (BMI) >85
percentile.
A total of 181 cases were identified; 31 (17%) had NAFL, 121 (67%) had NASH; 12 (6.6%) had ALD (AIH, PSC, or overlap), and 17 (9.4%) had combined ALD and NAFLD. Antinuclear antibody (ANA), Anti-actin, and liver kidney-microsomal (LKM) antibodies were positive in 16.1%, 13.8%, and 0% of NAFL and 32.8%, 15.5%, and 0% of NASH cases, respectively. Total IgG was elevated in 27.3% of NAFL and 47.7% of NASH cases but in 100% of ALD cases. The positive predictive value of LKM for ALD was 100% but was only 29% for ANA and 46% for anti-actin antibody.
False positive rates of autoantibodies were higher in pediatric patients with overweight and obesity with NAFLD compared with the adult general population. Positive LKM had the highest specificity and positive predictive value, and elevated IgG level had the highest sensitivity for ALD. The presence of autoantibodies does not signal more severe NAFLD in children. BMI > 98th percentile seems to be an important breakpoint above which ALD is less likely.

To characterize the neuropsychological outcome of children with CHD at age 5; the stability of cognitive and language abilities across childhood; and to identify early neurodevelopmental markers of neuropsychological outcomes in these children.
Five-year-old children (n=55) with complex CHD were assessed using standardized and comprehensive neuropsychological measures. Stability of language and cognitive performance was assessed by comparing standardized scores between ages 1, 2 and 5 years old. Association between 5-year-old skills and scores obtained in early childhood was studied to identify potential early markers of preschool performance. Receiver operating characteristic curves were used to evaluate the classification accuracy of Bayley Scales of Infant Development (BSID-III) scales in identifying later impairments.
At age 5, our cohort obtained scores significantly below the norms on most developmental domains, with 35 to 65% of participants showing impaired short-term/working memory, attention aevelopment, which reinforces the need for long-term monitoring and systematic assessment before school entry.
To investigate the trend of 1-year mortality and neonatal morbidities in preterm infants with serious congenital heart disease (CHD).
Cohort study using a population based administrative dataset of all liveborn infants 26-36 weeks gestational age (GA) with serious CHD born in California from 2011 to 2017. We assessed 1-year mortality and major neonatal morbidity (retinopathy of prematurity, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage > grade II, periventricular leukomalacia) across the study period and compared these outcomes to infants without CHD.
We identified 1921 preterm infants with serious CHD. The relative risk (RR) of death decreased by 10.6% for each year (RR 0.89, 95% CI 0.84-0.95) of the study period. The RR of major neonatal morbidity increased by 8.3% for each year (RR 1.08, 95% CI 1.02-1.15). When compared with preterm neonates without any CHD (n=234,522), the adjusted risk difference (ARD) for mortality was highest at 32 weeks of GA (9.7%, 95% CI 8.3-11.2), for major neonatal morbidity it was highest at 28 weeks (21.9%, 95% CI 17.0-26.9) and for the combined outcome it was highest at 30 weeks (ARD 26.7, 95% CI 23.3-30.1).
Mortality in preterm neonates with serious CHD decreased over the last decade, and major neonatal morbidity increased. Preterm infants with a GA of 28-32 weeks have the highest mortality or morbidity when compared with their peers without CHD. These results support the need for specialized and focused medical neonatal care in preterm neonates with serious CHD.
