- Objective: Exercise has widely documented cardioprotective effects, but the mechanisms underlying these effects are not entirely known. Previously, we demonstrated that aerobic but not strength training lowered resting heart rate and increased cardiac vagal regulation, changes that were reversed by sedentary deconditioning. Here, we focus on the sympathetic nervous system and test whether aerobic training lowers levels of cardiovascular sympathetic activity in rest and that deconditioning would reverse this effect. Methods: We conducted a randomized controlled trial contrasting the effects of aerobic (A) versus strength (S) training on indices of cardiac (preejection period, or PEP) and vascular (low-frequency blood pressure variability, or LF BPV) sympathetic regulation in 149 young, healthy, and sedentary adults. Participants were studied before and after conditioning, as well as after 4 weeks of sedentary deconditioning. Results: As previously reported, aerobic capacity increased in response to conditioning and decreased after deconditioning in the aerobic, but not the strength, training group. Contrary to prediction, there was no differential effect of training on either PEP (A: mean [SD] -0.83 [7.8] milliseconds versus S: 1.47 [6.69] milliseconds) or LF BPV (A: mean [SD] -0.09 [0.93] lnmm Hg-2 versus S: 0.06 [0.79] lnmm Hg-2) (both p values >.05). Conclusions: These findings, from a large randomized controlled trial using an intent-to-treat design, show that moderate aerobic exercise training has no effect on resting state cardiovascular indices of PEP and LF BPV. These results indicate that in healthy, young adults, the cardioprotective effects of exercise training are unlikely to be mediated by changes in resting sympathetic activity.

- We studied Swedish survey responders who reported regular treatment with hypnotic drugs, to find associations to perceived health problems, inpatient psychiatric diagnoses, and subsequent suicide. Among 32,679 sampled Swedes, 26,952 (83%) participated, 500 of which (2%) reported regular hypnotic drug treatment. The rate of treatment was higher in women, and increased by age in both sexes. The major findings were high odds of concurrent psychoactive drug treatments, nervous symptoms and insomnia, as well as high rates of circulatory and musculoskeletal conditions in both sexes, with indicators of disability and sleep-disturbing symptoms. During a 15-year period, 35% of the men and 21% of the women who reported regular hypnotic drug treatment had also been admitted to inpatient psychiatric care. Substance abuse was diagnosed in 20% of the men and 4.3% of the women reporting hypnotic drug treatment. In multiple logistic regression models, the highest odds for regular hypnotic drug treatment were incurred by recent/current insomnia, nervous symptoms, and other psychoactive drug treatment. We conclude that therapy was principally given according to some current peer guidelines. Yet, further research is needed into the risk/benefit ratio of sustained hypnotic drug therapy in patients with qualifying somatic and psychiatric disorders to obtain a more uniformly based consensus.

- OBJECTIVE: To determine whether obstructive sleep apnea mediates the relationship between posttraumatic stress disorder (PTSD) and psychosomatic and somatic disorders and its implications for self-rated health (SRH) among Iraqi immigrants in the United States.METHODS: A random sample of immigrants who had left Iraq before the 1991 Gulf War (n = 145) or after (n = 205) and are residing in metropolitan Detroit responded to a structured interview covering questions on sociodemographics, premigration trauma, SRH, physician-diagnosed and -treated obstructive sleep apnea, somatic disorders, and psychosomatic disorders. Structural equation modeling was used to evaluate the relationship between premigration trauma scores and health, as well as to explore mediating pathways between PTSD, obstructive sleep apnea, and health.RESULTS: The prevalence of obstructive sleep apnea among post-Gulf Warimmigrants (30.2%) was significantly higher than among pre-Gulf War immigrants (0.7%; p < .001). Premigration trauma scores were positively associated with depression and PTSD. Structural equation modeling supported a model in which obstructive sleep apnea mediated the relationship between PTSD and psychosomatic and somatic disorders. Premigration trauma also related directly to SRH.CONCLUSIONS: Part of the PTSD-associated adverse health effects observed in Iraqi immigrants is mediated by obstructive sleep apnea. Because sleep apnea in the current study is based on medical history and current treatment, there is a need for future confirmatory polysomnographic studies.

- Background: Alterations in brain-gut communication and the intestinal microenvironment have been implicated in a variety of medical and neuropsychiatric diseases. Three central areas require basic and clinical research: (1) how the intestinal microenvironment interacts with the host immune system, central nervous system, and enteric nervous system; (2) the role of the intestinal microenvironment in the pathogenesis of medical and neuropsychiatric disease; and (3) the effects of diet, prebiotics, probiotics, and fecal microbiota transplantation on the intestinal microenvironment and the treatment of disease. Methods: This review article is based on a symposium convened by the American Gastroenterology Association and the American Psychosomatic Society to foster interest in the role of the intestinal microenvironment in brain-gut communication and pathogenesis of neuropsychiatric and biopsychosocial disorders. The aims were to define the state of the art of the current scientific knowledge base and to identify guidelines and future directions for new research in this area. Results: This review provides a characterization of the intestinal microbial composition and function. We also provide evidence for the interactions between the intestinal microbiome, the host, and the environment. The role of the intestinal microbiome in medical and neuropsychiatric diseases is reviewed as well as the treatment effects of manipulation of the intestinal microbiome. Conclusions: Based on this review, opportunities and challenges for conducting research in the field are described, leading to potential avenues for future research.

- Objective Diabetes is frequently linked with depression, and both conditions are common complications during pregnancy. However, research findings exploring the relationship between diabetes mellitus in pregnancy (DMP) and perinatal depression (PND) have been inconsistent. Thus, this study seeks to examine the association between DMP and PND in a prospective population-based cohort.Methods Women aged 18 to 48 years (n = 4459) were identified from the Biology, Affect, Stress, Imaging and Cognition study. The diagnosis of DMP was based on International Classification of Diseases code O24 from medical records and was classified as pregestational, gestational, or unspecified diabetes. PND was assessed using psychometric instruments, clinical interviews, and/or register data and categorized into antepartum or postpartum depression. Multivariable logistic regressions were used to study the associations of DMP with antepartum and postpartum depression. The association between DMP and continuous depression scores, antepartum and postpartum, was investigated with multivariable linear regressions.Results Of 4459 pregnancies, 949 women had antepartum depression (21.2%) and 1123 had postpartum depression (25%). DMP had a prevalence of 1.2%. Women with DMP had twofold higher odds for postpartum depression compared with women without DMP. Although no association was observed between DMP and antepartum depression, DMP was associated with higher antepartum depression scores.Conclusions Our study shows an association between DMP and PND, which might be considered a risk factor when screening for high-risk groups.
