BACKGROUND: Adults with bipolar disorder demonstrate significantly poorer psychosocial functioning and neurocognition compared to controls. In adult bipolar disorder neurocognition predicts a substantial portion of variance in functioning. Adolescents with bipolar disorder have reducedpsychosocial functioning, but less is known about neurocognitive impairments, and no studies have examined the relationship between neurocognition and functioning in an adolescent sample. METHODS: 38 adolescents with bipolar disorder and 49 healthy controls under 20 years of age completed assessments of psychosocial functioning, neurocognitive ability, and psychiatric symptoms...

To perform a study to clarify how strong the chronological age relates to ossification of the knee in Chinese on X-rays and the MRI when a similar four-stage grading system was used. 322 individuals with conventional radiographs and MRI were collected from routine medical investigations and evaluated retrospectively. Bland Altman plots were performed to reveal the agreement of grading of MRI and radiograph. Regression analysis was conducted to establish a mathematical model for age estimation. The ossification process of the knee occurs earlier in females than in males for about 1-2 years...

BACKGROUND: Urine cadmium (Cd) and renal function biomarkers, mostly analysed in urine spot samples, are well established biomarkers of occupational exposure. Their use and associations at low environmental level are common, but have recently been questioned, particularly in terms of physiological variability and normalisation bias in the case of urine spot samples. AIM: To determine the appropriateness of spot urine and/or blood Cd exposure biomarkers and their relationships with renal function biomarkers at low levels of exposure...

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are commonly used in industrial applications and consumer products, and their potential health impacts are of concern, especially for vulnerable population like fetuses. However, in utero exposure to PFASs and health implications are far from fully characterized in China. To fill in the gap, we analyzed 10 PFASs in cord plasma samples (N=687) collected in Shanghai between 2011 and 2012, one of the regions widely polluted with PFASs in China. A questionnaire survey on maternal and diet-related factors was conducted...

BACKGROUND: Child pedestrian-motor vehicle collisions (PMVCs) have decreased in Canada in the past 20 years. Many believe this trend is explained by the rise in automobile use for all travel. Initiatives to increase walking to school need to consider PMVC risk. Potential risk factors related to walking to school, the built environment and social factors were examined for schools with historically high child PMVC rates. METHODS: Child PMVCs (age 4-12 years) from 2000 to 2013 and built environment features were mapped within school attendance boundaries in the City of Toronto, Canada...

BACKGROUND: A new computer model for systolic pulse waves within the cardiovascular system is presented. The emphasis was made on blood stroke volume (BS). The new waveform for pulse wave demands the re-computing of the BS. The authors showed the applicability of suggested model for arterial aging problem. METHODS: Suggested model is based on the well-known Korteweg-de Vries (KdV) equation. Instead of the common accepted solitary wave, the periodical cnoidal wave is used...

BACKGROUND: Previous studies of patients with bipolar disorder (BD) using magnetic resonance spectroscopy (MRS) have shown neurophysiological abnormalities related to the glutamate (Glu)-glutamine (Gln) cycle, membrane turnover, and neuronal integrity, although the results were neither consistent nor conclusive. Recently it has been reported the Gln/Glu ratio is the most useful index, quantifying neuronal-glial interactions and the balance of glutamatergic metabolites In this MRS study, we elucidated the abnormalities of metabolites in a larger sample of patients with BD with a high-field MRI system...

INTRODUCTION: Cardiac function is a key player in maintaining energy homeostasis in the brain. Heart failure is closely related to higher risk of neurocognitive disorders. Recent evidence shows that this relationship might not be limited to patients with advanced heart failure, and even suboptimal cardiac functioning is associated with accelerated brain aging. Hence, hemodynamic and serum cardiac markers may provide valuable information about the risk of dementia. METHODS: We provide an overview on the link between cardiac markers and cognitive function by a systematic search in five databases...

Previously, we have shown that flies under-expressing the two mitochondrial peroxiredoxins (Prxs), dPrx3 and dPrx5, display increases in tissue-specific apoptosis and dramatically shortened life span, associated with a redox crisis, manifested as changes in GSH:GSSG and accumulation of protein mixed disulfides. To identify specific pathways responsible for the observed biological effects, we performed a transcriptome analysis. Functional clustering revealed a prominent group enriched for immunity-related genes, including a considerable number of NF-kB-dependent antimicrobial peptides (AMP) that are up-regulated in the Prx double mutant...

Chronic myeloid leukemia (CML) treatment is based on company-sponsored and academic trials testing different tyrosine kinase inhibitors (TKIs) as first-line therapy. These studies included patients selected according to many inclusion-exclusion criteria, particularly age and comorbidities, with specific treatment obligations. In daily clinical practice (real-life), inclusion-exclusion criteria do not exist and the treatment outcome does not only depend on the choice of first-line TKI, but also on second- and third-line TKIs...

BACKGROUND: Autologous breast reconstruction is associated with long-term patient satisfaction that is superior to implant-based approaches. Occasionally, however, patients who desire autologous reconstruction present with inadequate donor-site volume. A hybrid approach, combining free flap reconstruction with simultaneous implant placement, is a solution. We present our experience with the use of mesh for improved pocket control using this reconstructive modality. METHODS: A retrospective analysis of a prospectively maintained database of patients undergoing autologous breast reconstruction was performed...

One-third of community-dwelling people older than 65 years of age fall each year, and half of them fall at least twice a year. Older care home residents are approximately three times more likely to fall when compared to community-dwelling older people. Risk indicators for falls are related to the older people's body, environment, behavior, and activities. An important health risk indicator is (orthostatic or postprandial) hypotension, which may induce cerebral hypoperfusion. Although the majority of falls remain without major consequences, 10% to 25% of falls in care homes result in bodily trauma...

Type 2 diabetes mellitus (T2DM) has consistently been associated with decreased risk of prostate cancer, however, if this decrease is related to the use of anti-diabetic drugs is unknown. We prospectively studied men in the comparison cohort in the Prostate Cancer data Base Sweden (PCBaSe) 3.0, with data on T2DM, use of metformin, sulphonylurea, and insulin retrieved from national health care registers and demographic databases. Cox proportional hazards regression models were used to compute hazard ratios (HR) and 95% confidence intervals (CI) of prostate cancer, adjusted for confounders...

Of the 100 types of human papillomaviruses (HPV), approximately 35 infect the genital tract. The viruses are categorized as "high risk" and "low risk" depending on whether they are known to cause cancer or not. Cervical cancer is an important cause of cancer mortality in Georgia, and worldwide. Only limited and incomplete data are available about the epidemiology of HPV infection and related molecular and cellular changes in Georgia. Objectives of our study included the estimation of the prevalence and the distribution of HPV genotypes among women in Georgia...

Rotavirus (RV) is the most common cause of severe gastroenteritis in infants and young children worldwide. RV causes approximately half a million deaths each year among children aged <5 years. According to WHO estimates for 2008, there were approximately 10 to 50 deaths annually in young children due to rotavirus diarrhea in Georgia. The purpose of this study was to assess the knowledge, attitudes, and practices related to rotavirus diarrhea and the rotavirus vaccine among health care workers (HCWs). The National Center for Disease Control and Public Health (NCDC) conducted a cross-sectional survey of HCWs involved in the expanded program of immunization (EPI)...

We review the hypotheses concerning the association between the paternal age at childbearing and childhood psychiatric disorders (autism spectrum- and attention deficit/hyperactive disorder) and adult disorders (schizophrenia, bipolar-, obsessive-compulsive-, and major depressive disorder) based on epidemiological studies. Several hypotheses have been proposed to explain the paternal age effect. We discuss the four main-not mutually exclusive-hypotheses. These are the de novo mutation hypothesis, the hypothesis concerning epigenetic alterations, the selection into late fatherhood hypothesis, and the environmental resource hypothesis...
