Advanced pharmaco-epidemiological methods have been used to address confounding in studies of antipsychotic medications in pregnancy, to provide data about the benefits and risks of treatment for women and their care providers.

Use of these data has advanced the field of research in schizophrenia and pregnancy. Future developments in use of electronic health records include access to richer data sources and use of modern technical advances such as machine learning and supporting team science.

Little is known about the impact of interpersonal betrayal experiences on mental health. Research suggests a link between betrayal and mental contamination (MC) within some forms of obsessive compulsive disorder (OCD). This study represents an initial exploration of that link in clinical samples.

A measure for assessing perceptions of betrayal was developed and evaluated (Study 1) in order to assess the extent of specificity of any association between the impact of betrayal and MC, and to estimate the extent of the impact of betrayal across common psychological disorders (Study 2).

In Study 1, the Perception of Betrayal Scale (POBS) was completed by 217 community participants; an exploratory principal components analysis identified the dimensional structure of the POBS. GW806742X research buy Study 2 was based on a cross-sectional, between-groups design, with three clinical groups [OCD (n = 23), other anxiety disorders (n = 21) and depression (n = 18)] and a non-clinical control group (n = 21). Three clinical groups (OCD, other anxiety disorders, and depression) and a community group completed a selection of measures via questionnaire.

In Study 1, the POBS was found to have an internal consistency of α = .95, and four factors were identified preoccupation with betrayal events, belief that betrayal had caused major life change, lack of trust due to betrayal and betrayal leading to traumatic responses. In Study 2, the OCD group scored more highly in terms of maladaptive perceptions of betrayal than the other groups. Regression analysis showed betrayal scores to be a moderate predictor of the experience of MC; the POBS subscales lack of trust due to betrayal and betrayal leading to traumatic responses were found to be significantly associated with MC. Although there was some overlap with bitterness, betrayal better predicted MC.

Findings support the hypothesis of a specific relationship between the construct of betrayal and MC.

Changes in autonomic nervous system (ANS) function have been observed in a variety of psychological disorders, including posttraumatic stress disorder (PTSD). Analysis of heart rate variability (HRV) provides insight into the functioning of the ANS. Previous research on PTSD found lower HRV in PTSD patients compared to controls, indicating altered sympathetic and parasympathetic activity, but findings are inconsistent. The purpose of this meta-analysis was to examine differences in HRV indices between individuals with PTSD and healthy controls at baseline and during stress.

The included primary studies present an aggregate of studies analyzing different HRV indices. Examined HRV indices were standard deviation of the normalized NN-intervals (SDNN), root mean square of successive differences (RMSSD), low-frequency (LF) and high-frequency (HF) spectral components, LF/HF ratio, and heart rate (HR). Moderating effects of study design, HRV and PTSD assessment, and sample characteristics were examined via subgroup-analyses and meta-regressions.

Random-effects meta-analyses for HRV parameters at rest revealed significant group differences for RMSSD and HF-HRV, suggesting lower parasympathetic activity in PTSD. The aggregated effect size for SDNN was medium, suggesting diminished total variability in PTSD. A small effect was found for LF-HRV. A higher LF/HF ratio was found in the PTSD sample as compared to controls. Individuals with PTSD showed significantly higher HR. During stress, individuals with PTSD showed higher HR and lower HF-HRV, both indicated by small effect sizes.

Findings suggest that PTSD is associated with ANS dysfunction.

Recently, there have been some discussions regarding level of processing as a descriptor to define food products, including cereal-based foods. This has led to a somewhat emotional debate on food processing. Given the widespread inclusion of cereals in the diet, this review highlights the history of cereal processing as well as their consumption by humans. It provides an evidence-based discussion on their production, contribution to human nutrition, benefits and disadvantages. The present review illustrates the impact of processing on nutrients, as well as non-nutrients specifically in bread and ready-to-eat breakfast cereals (RTEC), two cereal-based foods which are widely consumed and integral parts of food-based dietary guidelines globally. As a category, most cereals must be processed in some way to enable consumption by humans as we are not equipped to survive exclusively on raw grains. Even thousands of years ago, the processing of cereals was a common practice by humans, turning raw grains into palatable, safe and nutritious foods. Modern processes for cereal-based products are efficient in providing safe and good-quality products to satisfy population needs, as well as helping to meet consumer expectations by providing a range of foods that allows for a varied and balanced diet. Today, RTEC and bread make significant contributions to dietary energy and nutrient requirements and underpin food-based dietary guidance globally. They have been positively linked with intake of dietary fibre, vitamins and minerals, especially when consumed as whole grain.
