OBJECTIVE: To evaluate whether psychologic intimate partner violence (IPV) during pregnancy is a risk factor for intrauterine growth restriction (IUGR). METHODS: The cross-sectional study enrolled 810 randomly selected mothers of infants younger than 5 months attending basic health services in Rio de Janeiro, Brazil, from January to July 2007. Psychologic and physical IPV were evaluated by the Revised Conflict Tactics Scale; IUGR was defined as below the 10th percentile of the Alexander curve...

OBJECTIVE: A recent meta-analysis found that DSM-III- and DSM-IV-defined traumas were associated with only slightly higher posttraumatic stress disorder (PTSD) symptoms than nontraumatic stressors. The current study is the first to examine whether DSM-5-defined traumas were associated with higher levels of PTSD than DSM-IV-defined traumas. Further, we examined theoretically relevant event characteristics to determine whether characteristics other than those outlined in the DSM could predict PTSD symptoms...

Background: Migrants have been hypothesised to use different migration strategies between seasons: a time-minimization strategy during their pre-breeding migration towards the breeding grounds and an energy-minimization strategy during their post-breeding migration towards the wintering grounds. Besides season, we propose body size as a key factor in shaping migratory behaviour. Specifically, given that body size is expected to correlate negatively with maximum migration speed and that large birds tend to use more time to complete their annual life-history events (such as moult, breeding and migration), we hypothesise that large-sized species are time stressed all year round...

Memory functions can be considerably affected by various life events and stress has shown to be a chief regulator. Different stress patterns have distinct effects on the overall functioning of the brain. Stress provokes inflammation not only in the periphery but also in the brain. Neuroinflammation causes alterations in neuronal structure and function, which eventually progress to the development of neurodegenerative diseases. Inflammatory reactions are modulated through communication between the nervous, endocrine and immune systems...

BACKGROUND: A major determinant in cardiovascular disease (CVD) is stress. As transcendental meditation (TM) is thought to help in lowering negative stress indicators, it may be a beneficial strategy for the primary prevention of CVD. OBJECTIVES: To determine the effectiveness of TM for the primary prevention of CVD. SEARCH METHODS: We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 10); MEDLINE (Ovid) (1946 to week three November 2013); EMBASE Classic and EMBASE (Ovid) (1947 to week 48 2013); ISI Web of Science (1970 to 28 November 2013); and Database of Abstracts of Reviews of Effects (DARE) and Health Technology Assessment Database and Health Economics Evaluations Database (November 2013)...

BACKGROUND: The loss of a spouse is a major life event. Previous research found that centrality of the loss to one's identity using Centrality of Event Scale (CES) is related to complicated bereavement reactions, such as depression, posttraumatic stress symptoms (PTS), and prolonged grief symptoms (PGS). This study aims to examine loss-centrality in elderly bereaved people up to 4 years post loss, to determine the relation of loss-centrality to complicated bereavement reactions, such as PGS, depression, and PTS, and to identify early predictors of loss-centrality...

BACKGROUND: Empirical research demonstrates that there is a tendency to administer tumor-directed therapy to patients with advanced cancer close to death, especially if they are young. The aim of this qualitative study was to understand oncologists' treatment decisions and oncology nurses' perception of these decisions in young adult patients and to investigate the extent to which young age was a factor in cancer treatment decisions. MATERIALS AND METHODS: We conducted 29 face-to-face interviews with oncologists and oncology nurses at the Department of Hematology and Oncology at the University Hospital in Munich, Germany...

BACKGROUND: Genetic risk and environmental adversity-both important risk factors for major depression (MD)-are thought to differentially impact on depressive symptom types and associations. Does heterogeneity in these risk factors result in different depressive symptom networks in patients with MD? METHODS: A clinical sample of 5784 Han Chinese women with recurrent MD were interviewed about their depressive symptoms during their lifetime worst episode of MD. The cases were classified into subgroups based on their genetic risk for MD (family history, polygenic risk score, early age at onset) and severe adversity (childhood sexual abuse, stressful life events)...

Ten to eleven years after the September 11, 2001 terrorist attacks, probable posttraumatic stress disorder (PTSD) was evaluated in 1,755 World Trade Center (WTC) evacuees based on data from the WTC Health Registry. Characteristics of men and women were compared and factors associated with PTSD symptom severity were examined using the PTSD Checklist (PCL). Compared with men (n = 1,015, 57.8%), women (n = 740, 42.2%) were younger and of lower socioeconomic status. Ten to eleven years after September 11, 2001, 13...

A number of studies have shown that the presence of short (S) allele of the serotonin transporter-linked polymorphic region (5-HTTLPR) is associated with a higher risk for depression following exposure to stressful life events. These findings are in line with neuroimaging studies showing that 5-HTTLPR polymorphism has an effect on the connectivity among key areas involved in emotion regulation. Here using mediated moderation analysis, we show that electrophysiological manifestations of resting state networks in the alpha frequency band mediate the effect of 5-HTTLPR by stress interaction on depression/anxiety symptoms in a nonclinical sample...

BACKGROUND: Women with pathogenic BRCA germline mutations have an increased risk for breast and ovarian cancer that seems to be modified by life-style factors. Though, randomized trials investigating the impact of lifestyle interventions on cancer prevention and prognosis in BRCA carriers are still missing. METHODS: We implemented a multicenter, prospective randomized controlled trial in BRCA1/2 patients, comparing a lifestyle intervention group (IG) with a control group (CG) with the primary aim to prove feasibility...

Resilience is a multi-dimensional construct associated with health and well-being. At present, we do not yet have a valid, scientific instrument that is designed to evaluate adult resilience in Spanish-speaking countries and that accounts for family, social and individual components. This study aimed at investigating the construct and cross-cultural validity of the Resilience Scale for Adults (RSA) by combining Confirmatory Factor Analysis (CFA), Multidimensional Scaling (MDS) and Hierarchical Regression models in a Hispanic Latin-American group...

PTSD (Posttraumatic Stress Disorder) is a common post-disaster psychological condition which research has shown to have comorbidity with depression. To explore the relationship between PTSD and depression further, a cross-sectional study design was adopted. Three years after the Ya'an earthquake, 4137 adolescents (mean age 15.12) who had personally experienced the earthquake were assessed. The study results showed that PTSD significantly predicted future depression, with the effect being partially mediated by the negative life events after the earthquake...

OBJECTIVE: To assess the impact of maternal smoking during pregnancy (MSDP) on the neonatal hypothalamic-pituitary-adrenal axis. STUDY DESIGN: In a prospective observational study, salivary cortisol and cortisone levels were measured at the fourth day of life during resting conditions and in response to a pain-induced stress event in healthy neonates whose mothers smoked cigarettes during each stage of pregnancy and compared with controls. RESULTS: Neonates in the control group (n=70) exhibited a physiologic stress response with a significant increase in cortisol (1...

REVIEW
Pratibha Singhi, Arushi Gahlot Saini
Syncope is defined as a sudden, self-limited loss of consciousness and postural tone followed by spontaneous and complete recovery without any neurological sequelae. It is one of the most common paroxysmal disorders in children and adolescents. The three major causes of syncope in children are neural, cardiovascular and other non-cardiovascular causes. The common unifying mechanism is transient global hypoperfusion of the brain. The diagnosis is primarily clinical and objective laboratory investigations add little to the diagnosis in children especially in neurocardiogenic subtype...

Early identification of atherosclerosis and at-risk lesions plays a critical role in reducing the burden of cardiovascular disease. While invasive coronary angiography serves as the gold standard for diagnosing coronary artery disease, non-invasive imaging techniques provide visualization of both anatomical and functional atherosclerotic processes prior to clinical presentation. The development of cardiac positron emission tomography (PET) has greatly enhanced our capability to diagnose and treat patients with early stages of atherosclerosis...

In Caenorhabditis elegans, the programmed repression of the heat shock response (HSR) accompanies the transition to reproductive maturity, leaving cells vulnerable to environmental stress and protein aggregation with age. To identify the factors driving this event, we performed an unbiased genetic screen for suppressors of stress resistance and identified the mitochondrial electron transport chain (ETC) as a central regulator of the age-related decline of the HSR and cytosolic proteostasis. Mild downregulation of ETC activity, either by genetic modulation or exposure to mitochondria-targeted xenobiotics, maintained the HSR in adulthood by increasing HSF-1 binding and RNA polymerase II recruitment at HSF-1 target genes...

BACKGROUND: Both the nature and number of a wide range of prodromal symptoms have been related to the severity and type of psychopathology in the psychotic phase. However, at present there is an incomplete picture focused mainly on the positive pre-psychotic dimension. AIM: To characterize the prodromal phase retrospectively, examining the number and nature of prodromal symptoms as well as their relationship with psychopathology at the onset of first-episode psychosis...

Myocardial bridging, a congenital abnormality in which a coronary artery tunnels through the myocardial fibres was usually considered a benign condition. Many studies suggested a potential hemodynamic significance of myocardial bridging and some, usually case reports, implied a possible correlation between it and various cardiovascular pathologies like acute myocardial infarction, ventricular rupture, life-threatening arrhythmias, hypertrophic cardiomyopathy, apical ballooning syndrome or sudden death. The main objective of this article is to evaluate whether myocardial bridging may be associated with significant cardiac effects or if it is strictly a benign anatomical variation...
