Schizophrenia is a multifactorial developmental neuropsychiatric disorder. This study examined the interplay of maternal infection and postweaning social isolation, which are prenatal and postnatal risk factors, respectively. Pregnant mice received poly I:C or saline injection on gestation day 9 and the pups were weaned at postnatal day 28. After weaning, male offspring were randomly assigned into group-rearing and isolation-rearing groups. In their adulthood, we performed behavioral tests and characterized the histochemical features of their mesocorticolimbic structures. The sociability and anxiety levels were not affected by either manipulation, but synergistic effects of the two hits on stress-coping behavior was observed. Either of the single manipulations caused defects in sensorimotor gating, novel object recognition and spatial memory tests, but the combination of the two hits did not further exacerbate the disabilities. Prenatal infection increased the number of dopaminergic neurons in midbrain, whereas postweaning isolation decreased the GABAergic neurons in cortex. Single manipulation reduced the dendritic complexity and spine densities of neurons in the medial prefrontal cortex (mPFC) and dentate gyrus. Our results support the current perspective that disturbances in brain development during the prenatal or postnatal period influence the structure and function of the brain and together augment the susceptibility to mental disorders, such as schizophrenia.

Observational Descriptive Study

Background: Cerebral Palsy (CP) is a disability disorder motor motorization is most common in children with a prevalence of 2-3 per 1000 live births. The term CP is explained as a group of movement and posture disorders that are often accompanied by impaired sensation, perception, cognition, communication, behavior, epilepsy, and secondary disorders of the musculoskeletal system. Disorders of CP occur in the immature central nervous system with non-progressive traits occurring in the prenatal, perinatal, and postnatal period. Methods:  The purpose of this study is to determine how much prenatal risk factors, perinatal, and postnatal events in CP at the Kitty Center Clinic in Jakarta for 5 year (2013 - 2017). Result: An observational descriptive study, which described prenatal perinatal, and postnatal risk factors for CP events at the Kitty Center Clinic in Jakarta for a period of 5 years (2013-2017) with a total of 523 study subjects. Based on the analysis of data obtained, based on the type of CP 35% quadripelgia spastic, 36% spastic diplegia, 6% spastic hemiplegia, 9% athetosis, and 14% hypotonia. Based on sex 62% are men, and 38% are women with a ratio of 1.6: 1.0. Based on the age of the child 11% <2 years, 34% 3-6 years, 33% 7-12 years, and 22%13-18 years. Conclusion:  Based on risk factors of 62% prenatal, 25% perinatal, and 12% postnatal. Prenatal risk factor is the biggest risk factor as much as 62% which causes Cerebral Palsy at the Kitty Center Clinic in Jakarta.

And Function

Throughout the lifespan, common variations in systemic health and illness contribute to alterations in vasculature structure and function throughout the body, significantly increasing risk for cardiovascular and cerebrovascular disease (CVD). CVD is a prevalent cause of mortality in late life; it also promotes brain alterations, contributing to cognitive decline and, when severe, vascular dementia. Even prior to diseased states, individual variation in CVD risk is associated with structural and functional brain alterations. Yet, how cumulative asymptomatic alterations in vessel structure and function contribute to more subtle changes in brain tissue integrity and function that emerge in late life is unclear. Finally, vascular risk factors are associated with the clinical progression of neurodegenerative diseases such as Alzheimer’s disease (AD); however, recent theory posits that vascular degeneration may serve a contributory role in these conditions. This chapter reviews how lifespan changes in vascular health contribute to degenerative changes in neural tissue and the subsequent development of cognitive impairment and/or vascular dementia. It first discusses associations between vascular risk factors and cognition and also how declining vascular health may lead to cognitive impairment and dementia. Next, it identifies basic aspects of cerebrovascular anatomy and physiology sustaining tissue health and discusses how vulnerabilities of this system contribute to neurodegenerative changes. Finally, it reviews evidence of vascular contributions to AD and presents ideas for future research to better understand the full spectrum of cerebrovascular contributions to brain aging, cognitive decline, and dementia.

The Impact

Background:The personal and societal burden of knee osteoarthritis (KOA) urges the research community to identify factors that predict its onset and progression. A mechanistic understanding of disease is currently lacking but needed to develop targeted interventions. Traditionally, risk factors for KOA are termed ‘local’ to the joint or ‘systemic’ referring to whole-body systems. There are however clear indications in the scientific literature that contextual factors such as socioeconomic position merit further scientific scrutiny, in order to justify a more biopsychosocial view on risk factors in KOA.Objectives:The aims of this systematic literature review were to assess the inclusion of socioeconomic factors in KOA research and to identify the impact of socioeconomic factors on pain and function in KOA.Methods:Major bibliographic databases, namely Medline, Embase, CINAHL, Web of Science and Cochrane, were independently screened by two reviewers (plus one to resolve conflicts) to identify research articles dealing with socioeconomic factors in the KOA population without arthroplasty. Included studies had to quantify the relationship between socioeconomic factors and pain or function. Main exclusion criteria were: a qualitative design, subject age below 16 years and articles not written in English or Dutch. Methodological quality was assessed via the Cochrane risk of bias tools for randomized (ROB-II) and non-randomized intervention studies (ROBIN-I) and the Newcastle-Ottawa Scale for assessing the quality of non-randomised studies. Due to heterogeneity of studies with respect to outcomes assessed and analyses performed, no meta-analysis was performed.Results:Following de-duplication, 7639 articles were available for screening (120 conflicts resolved without a third reader). In 4112 articles, the KOA population was confirmed. 1906 (25%) were excluded because of knee arthroplasty and 1621 (21%) because of other issues related to the population definition. Socioeconomic factors could not be identified in 4058 (53%) papers and were adjusted for in 211 (3%) articles. In the remaining papers covering pain (n=110) and/or function (n=81), education (62%) and race (37%) were most frequently assessed as socioeconomic factors. A huge variety of mainly dichotomous or ordinal socioeconomic outcomes was found without further methodological justification nor sensitivity analysis to unravel the impact of selected categories. Although the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was the most popular instrument to assess pain and function, data pooling was not possible as socioeconomic factors estimates were part of multilevel models in most studies. Overall results showed that lower education and African American race were consistent predictors of pain and poor function, but those effects diminished or disappeared when psychological aspects (e.g. discrimination) or poverty estimates were taken into account. When function was assessed using self-reported outcomes, the impact of socioeconomic factors was more clear versus performance-based instruments. Quality of research was low to moderate and the moderating or mediating impact of socioeconomic factors on intervention effects in KOA is understudied.Conclusion:Research on contextual socioeconomic factors in KOA is insufficiently addressed and their assessment is highly variable methodologically. Following this systematic literature review, we can highlight the importance of implementing a standardised and feasible set of socioeconomic outcomes in KOA trials1, as well as the importance of public availability of research databases including these factors. Future research should prioritise the underlying mechanisms in the effect of especially education and race on pain and function and assess its impact on intervention effects to fuel novel (non-)pharmacological approaches in KOA.References:[1]Smith TO et al.

This study was undertaken in order to identify the relationship between gender of children with autism and risk factors before/during pregnancy and childbirth. An analysis of 66 clinical records was divided into two groups defined by gender of children diagnosed with autism in Bogotá (Colombia). The data were collected with the Maternal Perinatal Risk Questionnaire and analyzed with Pearson Chi square. The most significant risks associated with gender in the minors were voluntary abortions, maternal difficulties in a previous pregnancy, surgery during pregnancy, conflicting parental relationships, demanding physical and cognitive activity, consumption of drugs in the mother, duration of pregnancy and birth weight. Among men there was as many prenatal factors while among girls had an enrollment over perinatal factors (before and during labor) and psychosocial.

Introduction: Heart failure represents a significant public health problem because of increasing prevalence and lack of effective medical treatment. Hispanic/Latinos have a high burden of cardio-metabolic comorbidities and adverse socioeconomic conditions that place them at risk for heart failure. However, some literature indicates that among Hispanics/Latinos, residing in areas with high Hispanic/Latino ethnic density is associated with better health outcomes. There is a paucity of data on the effect of Hispanic/Latino ethnic density and risk markers for heart failure. Therefore, we evaluated the association between Hispanic/Latino ethnic concentration and several echocardiographic measures of left ventricular structure and function. Methods: Data on baseline characteristics from the Hispanic Communities Health Study/Study of Latinos (HCHS/SOL), echocardiographic measures of cardiac structure and function (ECHO-SOL), and neighborhood Hispanic/Latino ethnic density (San Diego SOL-CASAS) were analyzed. Hispanic/Latino ethnic density was calculated for each person based on an 800-m buffer around their home. Hispanic/Latino ethnic density was then calculated using data from the 2010 Census as the percent of Hispanic/Latinos divided by the total population at the Census block level and calculating an average value for all Census blocks that overlapped with the participant's address. Multivariable linear regression analysis adjusting for personal demographics and cardiovascular risk factors was conducted. Results: A total of 350 participants with data from all three databases were included in the analysis. The mean age was 55±7 years, 69% were female, and 26%, 38%, and 43% had diabetes, hypertension, and dyslipidemia, respectively. Thirty-six percent had less than high school education, and 58% were low income. In models adjusting for age, sex, education level, income, acculturation, and cardiovascular risk factors, a 1-percent higher Hispanic/Latino ethnic density was associated with lower left ventricular mass (0.47, p-value = 0.02). Other echocardiographic measures of cardiac structure and function were not significantly related to Hispanic/Latino ethnic density. Conclusion: Higher Hispanic/Latino ethnic density was associated with lower LVM independent of personal SES and common cardiovascular risk factors. These findings suggest that Hispanic/Latinos residing in areas with higher Hispanic/Latino ethnic density might have a lower risk of future HF. However, further research to understand the specific factors that mediate the observed associations are necessary.

Neonatal sepsis contributes significantly to neonatal morbidity and mortality and is a major public health challenge around the world. Depending on the mode of occurrence, a distinction is made between maternal-transmitted infection and that acquired in the postnatal period. Although the etiologies maternally transmitted diseases are well understood, those of postnatal acquired infections are variable depending on the epidemiology of each hospital environment. On the one hand, risk factors for maternal-transmitted infections are maternal sepsis, prolonged premature rupture of membranes, chorioamnionitis, and bacteriuria in the mother during pregnancy. On the other hand, risk factors for postnatal acquired infections are prematurity, low birth weight, lack of hygiene, and invasive therapeutic interventions. The diagnosis is based on a series of anamnestic, clinical and biological features. Although the positive diagnosis is based on the isolation of the germ by culture on a body sample (blood, cerebrospinal fluid, urine, etc.); its low sensitivity leads to the use of markers of the acute phase of inflammation such as C-reactive protein, procalcitonin and interleukins. New molecular biology techniques are promising and offer precise diagnosis with rapid results. Empirical management is a function of microbial ecology while definitive treatment is guided by the results of microbial culture. This article presents the essential elements for understanding neonatal sepsis and discusses new diagnosis and therapeutic management. It offers a thorough reading based on the issue of infections in newborns.

Introduction: Black Americans have more atrial fibrillation (AF) risk factors but lower AF risk than whites. Left atrial (LA) enlargement, impaired LA function, frequent premature atrial contractions (PAC), and atrial tachycardia (AT) are risk factors for AF. Racial differences in LA size and function, PAC, or AT may exist that could explain the difference in AF risk. Hypothesis: Whites have higher PAC and AT frequency than blacks. Additionally, whites have larger LA size and lower LA function than blacks, which may contribute to the racial difference in AF. Methods: We included 1,623 ARIC participants free of AF who had 2D-echocardiograms at visit 5 (2011-2013) and wore a 2-week continuous heart monitor, the Zio ® XT Patch, at visit 6 (2016-2017). Weighted linear regression was used to analyze the association of race with LA size and function, as well as runs of AT per day and PAC per hour. Results: At visit 5, participants were 74 (4) years old, 58% were female, and 26% were black. AT runs were detected in 87% of blacks and 92% of whites, respectively (p=0.002). Among participants with >0 runs of AT per day (n=1480), blacks had 48% (95% CI: 21%-66%) fewer runs of AT per day than whites after adjustment for cardiovascular (CV) risk factors † . There was no significant difference in PAC frequency between blacks and whites. After adjusting for age and sex, blacks had greater LA size and lower LA function than whites; these differences attenuated after adjusting for CV risk factors (Table). Conclusion: Blacks have greater age and sex-adjusted abnormality in LA size and function than whites, likely due to higher prevalence of CV risk factors. Yet, blacks have lower propensity for AT. More research is needed to elucidate the mechanisms underlying the resistance to atrial arrhythmogenesis in blacks despite greater adverse LA remodeling.

Neurodegenerative disorders are associated with a progressive loss of structure and function of neurones that leads to neuronal death. Their aetiology combines ageing, genetic susceptibility, and risk factors including environmental exposure, balanced against protective factors. They present with varying combinations of progressive cognitive, emotional, motor, autonomic and peripheral symptoms, and clinical signs. Neurodegenerative conditions are all likely to have a preclinical prodromal period, followed by slow initial decline during which there is clinical presentation, followed by a further steady decline and an eventual accelerated decline. The rate of progression of these disorders varies greatly, but they are all inevitably progressive, currently have no cure, and require symptomatic treatment.
