OBJECTIVE - The role of NOX2-containing NADPH oxidase in the development of diabetes is not fully understood. We hypothesized that NOX2 deficiency decreases reactive oxygen species (ROS) production and immune response and protects against streptozotocin (STZ)-induced β-cell destruction and development of diabetes in mice. RESEARCH DESIGN AND METHODS - Five groups of mice-wild-type (WT), NOX2-/-, WT treated with apocynin, and WT adoptively transferred with NOX2-/- or WT splenocytes - were treated with multiple-low-dose STZ. Blood glucose and insulin levels were monitored, and an intraperitoneal glucose tolerance test was performed. Isolated WT and NOX2-/- pancreatic islets were treated with cytokines for …

Pediatric urolithiasis has increased globally in the last few decades. There has been a change in the pattern of stone composition with an increase in the frequency of kidney stones and a decrease in bladder stones. The role of familial predisposition and environmental factors in pediatric urolithiasis is now better understood. Metabolic factors are more common in pediatric urolithiasis than in adult stone disease. This review updates on the epidemiology of pediatric urolithiasis with a focus on the changing trends in the stone disease, current spectrum of stone disease encountered in clinical practice, individual predisposition and the role of environmental …

A key goal of cognitive neuroscience is to find simple and direct connections between brain and behaviour. However, fMRI analysis typically involves choices between many possible options, with each choice potentially biasing any brain-behaviour correlations that emerge. Standard methods of fMRI analysis assess each voxel individually, but then face the problem of selection bias when combining those voxels into a region-of-interest, or ROI. Multivariate pattern-based fMRI analysis methods use classifiers to analyse multiple voxels together, but can also introduce selection bias via data-reduction steps as feature selection of voxels, pre-selecting activated regions, or principal components analysis. We show here that …
E-Mail Communication In Paediatrics: Ethical And Clinical Considerations, Susan Albersheim
E-Mail Communication In Paediatrics: Ethical And Clinical Considerations, Susan Albersheim
Paediatrics Publications
E-mail has become a commonplace ‘procedure’ in medical practice because it is efficient and inexpensive. However, there are potential misuses and abuses of this form of written communication, with clinical and ethical implications. Common uses of e-mail in paediatics include general communication with colleagues in a professional setting; electronic formal consultation, in which patient confidentiality is paramount; electronic ‘curbside’ consultation, which may be perceived as a formal consultation; electronic discussion groups, which lack peer review; communication with current patients or their parents, which should be limited to simple, nonurgent issues; and communication with individuals seeking medical advice who are not …

Purpose: To determine the effect of a Nutrition and Exercise Lifestyle Intervention Program (NELIP) for overweight (OW) and obese (OB) pregnant women on pregnancy weight gain, birth weight, and maternal weight retention at 2 months postpartum. Methods: This is a single-arm intervention matched by prepregnant body mass index, age, and parity to a historical cohort (4:1). Women with a prepregnancy body mass index of>25.0 kg•m (N = 65) participated in a NELIP starting at 16-20 wk of pregnancy, continuing until delivery. NELIP consisted of an individualized nutrition plan with total energy intake of approximately 2000 kcal•d (8360 kJ•d) and …

Although peroxisome proliferator activated receptor (PPAR)_ remains a critical regulator of preadipocyte differentiation, new roles have been discovered in inflammation, bone morphogenesis, endothelial function, cancer, longevity and atherosclerosis. Despite the demonstration of PPAR expression in chondrocytes, its role and the pathways affecting its expression and activity in chondrocytes remain largely unknown. We investigated the effects of PPAR activation on chondrocyte differentiation and its participation in chondrocyte lipid metabolism. PPAR2 expression is highly regulated during chondrocyte differentiation in vivo and in vitro PPAR activation with troglitazone resulted in increased Indian hedgehog expression and reduced collagen X expression, confirming previously described roles …

Many uncontrolled studies and a subsequent meta-analysis suggest that hemolytic uremic syndrome (HUS) with a positive history for diarrhea is associated with a significant increase in chronic renal disease. Two recent controlled studies that followed children with this type of HUS after Escherichia coli O157:H7 outbreaks, and where the controls were selected from a group exposed in the outbreak, gave conflicting results. To clarify this apparent difference, we retrospectively compared a cohort of 30 children with sporadic diarrhea-positive HUS with 30 healthy controls who had no history of bloody diarrhea or HUS and who had similar age and gender. Significantly …
