Does overweight in childhood have an impact on adult health?

The consequences of overweight in childhood, including persistence into adulthood and as a risk factor for adverse health consequences, are of substantial concern given the recent upward trend in prevalence. A recent report on an historic cohort--a British 1947 birth cohort--is largely consistent with previous estimates of persistence of overweight. Long-term health consequences of obesity were not demonstrable in this study, likely owing to the small numbers of subjects who were overweight during post-World War II Britain.     

Overweight,obesity, and associated disease burden in the Veterans Affairs ambulatory care population

BACKGROUND: This report describes the prevalence of overweight and obesity and estimates the disease burden associated with excess weight in ambulatory Veterans Affairs (VA) patients. METHODS: Height and weight were measured, and self-reported age and self-reported morbidities were obtained for 1,731 patients. Prevalence odds ratios explain the association of self-reported disease on increasing weight status category using body mass index. RESULTS: Seventy-five percent of the participants were overweight or obese. Obesity was significantly higher in the younger patients. Graded increases in odds ratios were observed with increasing severity of overweight and obesity for all morbidities, except heart disease. CONCLUSION: Overweight, obesity, and associated disease burden are prevalent in the VA health care system, particularly in younger VA patients, which may contribute to the higher prevalence of certain morbidities observed in VA populations compared with private sector outpatients. Department of Veterans Affairs should emphasize obesity prevention and treatment during the design and implementation of ambulatory care services.     

A novel cholinesterase and brain-selective monoamine oxidase inhibitor for the treatment of dementia comorbid with depression and Parkinson's disease

Degeneration of cholinergic cortical neurons is one of the main reasons for the cognitive deficit in dementia of the Alzheimer type (AD) and in dementia with Lewy bodies (DLB). Many subjects with AD and DLB have extrapyramidal dysfunction and depression resulting from degeneration of dopaminergic, noradrenergic and serotoninergic neurons. We prepared a novel drug, TV-3326 (N-propargyl-3R-aminoindan-5yl)-ethyl methylcarbamate), with both cholinesterase (ChE) and monoamine oxidase (MAO) inhibitory activity, as potential treatment of AD and DLB. TV-3326 inhibits brain acetyl and butyrylcholinesterase (BuChE) in rats after oral doses of 10-100 mg/kg. After chronic but not acute treatment, it inhibits MAO-A and -B in the brain by more than 70% but has almost no effect on these enzymes in the small intestine in rats and rabbits. The brain selectivity results in minimal potentiation of the pressor response to oral tyramine. TV-3326 acts like other antidepressants in the forced swim test in rats, indicating a potential for antidepressant activity. Chronic treatment of mice with TV-3326 (26 mg/kg) prevents the destruction of nigrostriatal neurons by the neurotoxin MPTP (N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine). In addition to ChE and MAO inhibition, the propargylamine moiety of TV-3326 confers neuroprotective activity against cytotoxicity induced by ischemia and peroxynitrite in cultured neuronal cells that results from prevention of the fall in mitochondrial membrane potential and antiapoptotic activity. These unique multiple actions of TV-3326 make it a potentially useful drug for the treatment of dementia with Parkinsonian-like symptoms and depression.     

Common Variations in 4p Locus are Related to Male Completed Suicide

Suicidal behavior is a multifactorial phenomenon, with a significant genetic predisposition. To assess the contribution of genes in the 4p region to suicide risk, we genotyped 36 single nucleotide polymorphisms from a 49Mb region on the chromosome arm 4p11-16 in a total of 288 male suicide victims and 327 healthy male volunteers. The nonsynonymous variants rs1383180 in EVC gene, rs6811863 in TBC1D1 gene, rs362272 in HTT gene, and rs734312 in WFS1 gene were associated to the male completed suicide. However, only EVC polymorphism remained significant after correcting for multiple comparisons (P < .05 after 10 K permutations). The function of these genes is not clear yet. WFS1 and HTT are related to the unfolded protein response and endoplasmic reticulum stress, and TBC1D1 is a GTPase activator. EVC is a protein with transmembrane and leucine zipper domains, its function has not been elucidated yet. Further studies are required in order to reveal the role of these four polymorphisms in the pathoetiology of suicide.

Presentation, natural history, and outcome in children and adolescents with double orifice mitral valve

Forty-six children, aged 2 days to 16 years (median 2.4 years) with double orifice mitral valve (DOMV), were studied. Partial atrioventricular septal defect was the most commonly associated cardiac lesion. Symptoms were related to the degree of mitral insufficiency and/or stenosis when present. Surgical intervention directed at DOMV was required in the minority of patients who underwent repair of associated cardiac lesions. The long-term morbidity attributable to DOMV was low.     

The handwriting performance of children with NF1

The objective of this study was to analyze the process and product of handwriting among children with Neurofibromatosis Type 1 (NF1) in comparison to those of Typically Developing (TD) children. Children with NF1 are at risk for some cognitive deficits, a wide range of deficits in perceptual skills and, motor and visual-motor integration skills which may interfere with handwriting competency, which is an essential ingredient for success at school. Participants were 30 NF1 children and 30 age and gender matched TD children, between the ages 8 and 16.08. The handwriting performance of children with NF1 was evaluated with the Beery–Buktenica Developmental Test of Visual-Motor Integration (VMI), for copying text and free style writing tasks, using: (1) Computerized Penmanship Evaluation Tool (ComPET) to assess mechanical aspects of the writing process. (2) The Hebrew Handwriting Evaluation (HHE) to examine product legibility. (3) The Six-Trait Writing Model to judge the quality of the written product. Significant differences between the NF1 children and the control group were found in the process and product measures. Significant correlations were found between the VMI, the ComPET, the HHE and the Six-Trait Writing Model variables for both groups. We suggest a possible relationship between executive dysfunction and poor performance in handwriting.
