Is this D vitamin to worry about? Vitamin D insufficiency in an inpatient sample.

Objective: The aim of the present study was to investigate the relationship between reduced serum vitamin D levels and psychiatric illness.

Method: This study was an audit of serum 25-hydroxyvitamin D (25-OHD) levels measured routinely in a sample of 53 inpatients in a private psychiatric clinic. These levels were compared with those of controls without psychiatric illness.

Serum levels of brain-derived neurotrophic factor in schizophrenia on a hypocaloric diet.

Dietary factors influence BDNF in animal studies, but there is no comparable data in clinical populations. We examined the effect of a dietary intervention on BDNF serum levels in 67 DSM-IV schizophrenic outpatients (51 males and 16 females). Two groups were assessed in a cross-sectional study: one on a hypocaloric diet (HD) and the other not on a hypocaloric diet.

Selective serotonin reuptake inhibitor use and bone mineral density in women with a history of depression.

Selective serotonin reuptake inhibitors (SSRIs) are a first-line treatment for depression. They have been reported to regulate serotonin signalling in bone cells and may influence bone metabolism. This study aimed to investigate the effect of SSRIs on bone mineral density (BMD) in a sample of women with a lifetime history of depression.

Leptin in depressed women: cross-sectional and longitudinal data from an epidemiologic study.

Background: There is conflicting evidence regarding levels of leptin in depression. In this study we aimed to investigate the relationship between serum leptin level and depression in a community sample of women using both cross-sectional and longitudinal data.

Methods: From among 510 women aged 20-78 yr, 83 were identified with a lifetime history of major depressive disorder or dysthymia, ascertained using the Structured Clinical Interview for DSM-IV-TR Research Version, Non-patient edition (SCID-I/NP).

Effects of a walking program in the psychiatric in-patient treatment setting: a cohort study.

Issue Addressed: To assess the effectiveness of a walking program in a psychiatric in-patient unit.

Method: In-patients at a private psychiatric unit were offered the opportunity to participate in a daily morning 40- minute walk led by an activity supervisor. After discharge, outcomes for patients who had regularly participated in the walking group (n=35) and patients who had not participated (n=49) were compared for length of stay during their period of admission and Clinical Global Impression-Severity (CGI-S) and Depression Anxiety Stress Scales (DASS) scores measured at admission and discharge.

Vitamin D deficiency may play a role in depression.

Vitamin D is known to be widely deficient in Western populations. The implications of this in terms of bone health are increasingly understood, yet its impact on other health areas, particularly mental health, is unclear. Recent data suggests that hypovitaminosis D may be common, especially in the elderly.

Self-reported depression and cardiovascular risk factors in a community sample of women.

The authors examined data collected from a randomly selected, representative sample of 755 women (ages 23-97 years) from southeastern Australia. Self-report questionnaires were utilized to determine lifetime rates of depression and cardiovascular risk factors within the study sample. A lifetime history of depression (LHx) was reported by 145 women (19.

Depression and pain: an overview.

Background: Depression and pain are both burdensome ailments that affect a major proportion of the population. It is evident that depression and pain frequently coexist, with treatment and outcome implications.

Objective: To review the literature on the nature, prevalence and co-morbidity of depression and pain, the biological and psychological mechanisms involved and treatment options, thus presenting a broad overview of the current information available.

Depression and bone mineral density in a community sample of perimenopausal women: Geelong Osteoporosis Study.

Objective: Reduced bone mineral density (BMD) in women with a history of depressive disorders has been shown in some, but not all studies. This study investigated the association between self-reported depression and BMD in an age-stratified community sample of perimenopausal women residing in the South-Eastern region of Australia.

Design: Symptoms of depression in the year between July 2000 and July 2001 were ascertained by a self-report questionnaire based on Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria.

The relationship between depression and cardiovascular disease.

Evidence from epidemiological studies has established that depression is a risk factor for the development of cardiovascular disease (CVD) and that the comorbidity of depression with pre-existing CVD worsens the prognosis for sufferers of CVD. Depression has also been associated with other behaviours that impact on CVD, such as medication non-compliance, and an unwillingness to adopt an exercise program, that reduce the likelihood of successful rehabilitation from CVD. Published literature on the current knowledge of the association between depression and CVD is reviewed in this paper.

Dietary omega-3 fatty acids and depression in a community sample.

To evaluate the association between omega-3 polyunsaturated essential fatty acids and depression, data regarding prevalence rates of self-reported depression and median daily dietary intakes of these fatty acids were obtained from an age-stratified, population-based sample of women (n = 755; 23-97 year) in the Barwon Statistical Division of south-eastern Australia. A self-report questionnaire based on Diagnostic and Statistical Manual-IV criteria was utilised to determine 12-month prevalence rates of depression in this sample, and data from biennial food frequency questionnaires examining seafood and fish oil consumption over a 6-year period were examined. Differences in median dietary intakes of omega-3 fatty acids between the depressed and nondepressed cohorts were analysed and results were adjusted for age, weight and smoking status.

High-pulse-repetition-freqyency lidar system using a single telescope for transmission and reception.

The design, construction, and operation of a stratospheric Rayleigh lidar system is outlined. The lidar system was designed to operate as a Doppler lidar; however, for the first stage of the project it was set up to operate in a manner similar to a more conventional stratospheric Rayleigh lidar. This system includes a number of unique design features, including a high-pulse-repetition-frequency laser and the use of a single 1-m-diameter telescope for transmission of the laser pulse and reception of the backscattered light.

Phototherapy of human tumours using haematoporphyrin derivative.

Photoradiation therapy (phototherapy) is a recently introduced treatment for malignant tumours, which depends on the activation of a photoreactive drug selectively localized to tumours. An experience in 27 patients with haematoporphyrin derivative is described. The haematoporphyrin derivative was activated by light of 630-nm wavelength, which was delivered to cutaneous tumours from a specially designed incandescent lamp and to deep tumours through a quartz fibre from a laser system.
