[The influence of maternal choline supplementation on fetal brain development and the risk of psychotic symptoms]. / De invloed van maternale cholinesuppletie op foetale hersenontwikkeling en het risico op psychose.

BACKGROUND: Choline is an essential micronutrient important for fetal brain development. Research suggests that maternal choline supplementation during pregnancy may reduce the risk of developing neuropsychiatric disorders such as psychosis in offspring. AIM: To provide a narrative review of evidence from the literature for the possible prevention of neuropsychiatric problems such as psychosis by maternal choline supplementation. METHOD: A narrative review of the literature obtained after searches in PubMed, Embase and PsycINFO. RESULTS: Nutritional studies indicate that most pregnant women do not receive sufficient dietary choline. This may have adverse effects on fetal brain development. A total of 8 studies were identified; 4 animal and 4 clinical studies. Beneficial effects of maternal choline supplementation were found on fetal brain development, including cognitive and psychosocial functioning of children. No evidence of (serious) side effects was found. Due to the relatively short duration and limited size of the studies, no conclusions could be drawn about the role of maternal choline supplementation in the prevention of neuropsychiatric problems such as psychosis. CONCLUSION: Maternal choline supplementation and/or a choline-rich diet during pregnancy should be further investigated because of evidence of beneficial effects on infant mental functioning, low cost and few side effects. There is no evidence that maternal choline supplementation can prevent psychotic symptoms in offspring.

Maternal choline supplementation during pregnancy to promote mental health in offspring.

AIM: There is increasing interest in the role of choline in brain development, including its possible role in promoting mental health and preventing mental illness. Choline is an essential micronutrient in fetal brain maturation. In more than 90% of pregnant women, choline intake has been found to be lower than the daily-recommended dose. The aim of this article is to review what is known about the effects of maternal choline supplementation on fetal brain development, early child development and mental health. METHODS: A narrative review of the literature. RESULTS: A limited number of studies suggest that maternal choline supplementation during pregnancy may enhance fetal brain development and improve early signs and symptoms that may predispose to mental illness. CONCLUSION: The general low maternal choline intake during pregnancy, expected health benefits and low risks, make a plea for maternal choline supplementation to promote mental health. Choline supplementation may be especially important for pregnant women with a (family) history of severe mental illness and/or alcohol dependence.

[Mindfulness training for psychiatrists in residency: a pilot study]. / Mindfulnesstraining voor aiossen psychiatrie: een pilotstudie.

BACKGROUND: Medical students and psychiatrists in residency run a high risk for burnout. Furthermore, while at medical school, students seem to experience a reduction in empathy; this seems to be linked to a high level of stress. Interventions based on mindfulness training appear to reduce stress and increase empathy in medical students. Trainees in psychiatric residency might also benefit from mindfulness training.
AIM: To assess the effects that a mindfulness course has on perceived stress and empathy in psychiatrists in residency.
METHOD: In this pilot study 13 trainees in psychiatric residency participated in an eight-week course in mindfulness. Before and after the training, 11 of the participants completed questionnaires relating to their empathy, perceived stress and mindfulness.
RESULTS: Participants reported experiencing considerably more empathy after their course than before it. Perceived stress also diminished, but not significantly.
CONCLUSION: The results support our suggestion that mindfulness training can be a valuable part of the curriculum for trainees in psychiatric residency.

Low essential fatty acid and B-vitamin status in a subgroup of patients with schizophrenia and its response to dietary supplementation.

We assessed essential fatty acid (EFA) and B-vitamin status, together with their determinants, in 61 patients with schizophrenia and established whether those with poor status responded biochemically to the appropriate dietary supplements. As a group, the patients had high erythrocyte saturated fatty acids (FAs), monounsaturated FA and low polyunsaturated FA of the omega3 and omega6 series. Patients reporting not to take vitamin supplements had low vitamin B12 and high homocysteine. Homocysteine variance proved best explained by folate in both the total group and male patients, and by vitamins B12 and B6 in females. Alcohol consumption and duration of illness are risk factors for low polyunsaturated FA status (< P2.5 of reference range), while male gender and absence of fish consumption predict hyperhomocysteinemia (> P97.5 of reference range). Two patients exhibited biochemical EFA deficiency and seven showed biochemical signs of omega3/docosahexaenoic acid (DHA) marginality. Four patients exhibited moderate hyperhomocysteinemia with plasma values ranging from 57.5 to 74.8 micromol/L. None of the five patients with either moderate hyperhomocysteinemia, biochemical EFA deficiency, or both, was predicted by their clinicians to have poor diets. That diet was nevertheless at the basis of these abnormalities became confirmed after supplementing 4 of them with B vitamins and with soybean and fish oils. We conclude that a subgroup of patients with schizophrenia has biochemical EFA deficiency, omega3/DHA marginality, moderate hyperhomocysteinemia, or combinations. Correction seems indicated in view of the possible relation of poor EFA and B-vitamin status with some of their psychiatric symptoms, but notably to reduce their high risk of cardiovascular disease.
