Characterisation of the British honey bee metagenome

Numerous microbial symbionts, both commensal and pathogenic, are associated with honey bees. Here, the authors genomically characterize this ‘metagenome’ of the British honey bee, identifying a diversity of commensal microbes as well as known and putative pathogen

The perinatal origins of major reproductive disorders in the adolescent : research avenues

The fetal endometrium becomes responsive to steroid hormones around the fourth month of pregnancy starting with an oestrogenic phase, which is followed late in pregnancy by a secretory phase. Based on post-mortem studies, the endometrium at birth is secretory in only one-third of neonates and proliferative in the remaining cases. Decidual or menstrual changes are rare in fetal endometrium despite high circulating steroid hormone levels, which drop rapidly after birth. Hence, acquisition of progesterone responsiveness appears to be dependent on endometrial maturation and relative immaturity may persist in a majority of girls until the menarche and early adolescence. Two major reproductive disorders have been linked with either advanced or delayed endometrial maturation. First, early-onset endometriosis may be caused by menstruation-like bleeding in the neonate, leading to tubal reflux and ectopic implantation of endometrial stem/progenitor cells. Second, persistence of partial progesterone resistance in adolescent girls may compromise deep placentation and account for the increased risk of major obstetrical syndromes, including preeclampsia, fetal growth retardation and preterm birth. The concept of neonatal origins of common reproductive disorders poses important research challenges but also subsumes potential new preventative strategies

'An Apple a Day'?: Psychiatrists, Psychologists and Psychotherapists Report Poor Literacy for Nutritional Medicine: International Survey Spanning 52 Countries.

Nutritional interventions have beneficial effects on certain psychiatric disorder symptomatology and common physical health comorbidities. However, studies evaluating nutritional literacy in mental health professionals (MHP) are scarce. This study aimed to assess the across 52 countries. Surveys were distributed via colleagues and professional societies. Data were collected regarding self-reported general nutrition knowledge, nutrition education, learning opportunities, and the tendency to recommend food supplements or prescribe specific diets in clinical practice. In total, 1056 subjects participated in the study: 354 psychiatrists, 511 psychologists, 44 psychotherapists, and 147 MHPs in-training. All participants believed the diet quality of individuals with mental disorders was poorer compared to the general population (p < 0.001). The majority of the psychiatrists (74.2%) and psychologists (66.3%) reported having no training in nutrition. Nevertheless, many of them used nutrition approaches, with 58.6% recommending supplements and 43.8% recommending specific diet strategies to their patients. Only 0.8% of participants rated their education regarding nutrition as 'very good.' Almost all (92.9%) stated they would like to expand their knowledge regarding 'Nutritional Psychiatry.' There is an urgent need to integrate nutrition education into MHP training, ideally in collaboration with nutrition experts to achieve best practice care
