Cognitive Costs of Reappraisal Depend on Both Emotional Stimulus Intensity and Individual Differences in Habitual Reappraisal.

Recent models of emotion regulation suggest that the cognitive costs of reappraisal depend on stimulus intensity and habitual reappraisal. In the current experiment, we tested these hypotheses by manipulating the intensity of unpleasant and pleasant images, which participants reappraised, viewed, or suppressed their emotions to. To assess cognitive costs, we measured participants' performance on a concurrent simple reaction time task.

Risky business: failure to prevent and failure to communicate.

Healthcare-associated infections (HAIs), important threats to patient safety, are considered differently from other adverse events. Gardam and his colleagues discuss several reasons for this and outline approaches that may bring about changes in attitudes and enhance HAI prevention. We comment on the potential preventability of HAIs, the need for improved communication strategies and the different vision of the role of infection control personnel suggested by Gardam et al.

Acute myelogenous leukemia and glycogen storage disease 1b.

Glycogen storage disease 1b (GSD 1b) is caused by a deficiency of glucose-6-phosphate translocase and the intracellular accumulation of glycogen. The disease presents with failure to thrive, hepatomegaly, hypoglycemia, lactic acidosis, as well as neutropenia causing increased susceptibility to pyogenic infections. We present a case of a young woman with GSD 1b who developed acute myelogenous leukemia while on long-term granulocyte colony-stimulating factor therapy.

Use of mouse mammary tumour virus (MMTV)/neu transgenic mice to identify genes collaborating with the c-erbB-2 oncogene in mammary tumour development.

Mouse mammary tumour virus (MMTV)/neu transgenic mice develop clonal or oligoclonal mammary tumours stochastically. The pathology of these tumours is very similar to that of human breast tumours. Moreover, these mouse tumours metastasize in the lungs.

Helicobacter pylori is not associated with nonspecific abdominal pain in children.

Nonspecific abdominal pain is a significant problem in the pediatric population, and there has been much recent interest in the role that Helicobacter pylori (HP) might play in this disorder. A retrospective review was conducted at our center to determine its prevalence among children with otherwise undiagnosed abdominal pain. The study was conducted over a 45-month period during which 47 patients underwent gastroscopy and antral biopsies in the workup of this problem.

Symposium on the treatment of inflammatory bowel disease in children and adolescents. Nutritional therapy.

Malnutrition contributes substantially to the severity and morbidity of inflammatory bowel disease in children. Causes of malnutrition include decreased oral intake, excessive nutrient losses, increased nutritional requirements and malabsorption. Nutritional therapy is used to correct specific deficiencies, delayed growth and puberty, and as primary therapy to achieve total bowel rest in patients with disease that is resistant to conventional medical treatment.

Correction of the malabsorption of the preterm infant with a medium-chain triglyceride formula.

After receiving milk-based formula for one week, 16 preterm infants, weighing 1,300 to 1,800 gm, were fed two isocaloric formulas containing either medium-chain or long-chain triglycerides for 15 days; the alternate formula was given for a second period of identical duration. While receiving MCT, the infants had greater (P smaller than 0.01) percent fat absorption (83.

Standardization of cardiopulmonary roentgenograms in infants and children.

Methods were devised to standardize cardiopulmonary radiographs of infants and children. With these techniques, films can be taken either at the end of inspiration and in systole, or at the end of inspiration alone. A statistical evaluation of these two methods demonstrated their superiority over the usual procedure.
