REVIEW

Life on earth has adapted to the day-night cycle by evolution of internal, so-called circadian clocks that adjust behavior and physiology to the recurring changes in environmental conditions. In mammals, a master pacemaker located in the suprachiasmatic nucleus (SCN) of the hypothalamus receives environmental light information and synchronizes peripheral tissues and central non-SCN clocks to geophysical time. Regulatory systems such as the hypothalamus-pituitary-adrenal (HPA) axis and the autonomic nervous system (ANS), both being important for the regulation of stress responses, receive strong circadian input...

BACKGROUND: Most studies evaluating neurocognitive outcomes in children with congenital heart defects (CHD) have focused on high-risk patients or used specialized, resource-intensive testing. To determine the association of CHD with academic outcomes and compare outcomes according to the severity of CHD, we linked state educational records with a birth defects registry and birth certificates. METHODS AND RESULTS: We performed a retrospective cohort study using data from the North Carolina Birth Defects Monitoring Program, North Carolina Department of Public Instruction, and North Carolina Department of Health and Human Services vital records...

INTRODUCTION: The Drinking Motives Questionnaire (DMQ) measures motives for alcohol consumption on four subscales. Coping with negative affect and enhancement of positive affect have been shown to be associated with high levels of alcohol consumption and alcohol-related problems. Few studies exist concerning drinking motives among treatment-seeking patients. The aims of the study were to investigate the factor structure of the shortened form of the revised DMQ (DMQ-R SF), map main drinking, explore group differences in motives due to sex, age, level of drinking problems and symptoms of depression/anxiety and to investigate whether different drinking motives predict alcohol-related problems in this group...

Although recent results show that 3-month-olds can discriminate complex tones by their missing fundamental, it is arguable whether they are discriminating on the basis of a perceived pitch. A defining characteristic of pitch is that it carries melodic information. This study investigated whether 3-month-olds, 7-month-olds, and adults can detect a change in a melody composed of missing fundamental complexes. Participants heard a seven-note melody and learned to respond to a change that violated the melodic contour...

A critical step in cellular-trafficking pathways is the budding of membranes by protein coats, which recent experiments have demonstrated can be inhibited by elevated membrane tension. The robustness of processes like clathrin-mediated endocytosis (CME) across a diverse range of organisms and mechanical environments suggests that the protein machinery in this process has evolved to take advantage of some set of physical design principles to ensure robust vesiculation against opposing forces like membrane tension...

Supplementation of micronutrients involved in DNA methylation, particularly during pregnancy, is recommended because of its impacts on human health, but further evidence is needed regarding the effects of over-supplementation and differences between sexes. Here, a porcine model was used to assess effects of maternal supplementation with one-carbon-cycle compounds during prenatal and postnatal stages on offspring muscle development. Sows received either a standard diet (CON) or a standard diet supplemented with folate, B6, B12, methionine, choline, and zinc (MET) throughout gestation...

Sickle cell disease is a risk factor for cerebrovascular accidents in the pediatric population. This risk is compounded by hypoxemia. Cyanotic congenital heart disease can expose patients to prolonged hypoxemia. To our knowledge, the long-term outcome of patients who have combined sickle cell and cyanotic congenital heart disease has not been reported. We retrospectively reviewed patient records at our institution and identified 5 patients (3 girls and 2 boys) who had both conditions. Their outcomes were uniformly poor: 4 died (age range, 12 mo-17 yr); 3 had documented cerebrovascular accidents; and 3 developed ventricular dysfunction...

BACKGROUND: Hyponatremia and delirium are frequent problems in older hospitalized patients. Although confusional states are considered to be a possible complication of hyponatremia, there has been no systematic study to date of the precise prevalence of delirium among patients with hyponatremia and its effect on long-term outcomes. METHODS: In a 13-month period in 2009/2010, all patients with a serum sodium level less than or equal to 130 mmol/L (the hyponatremia group) in a cohort of hospitalized older patients were studied and compared to a normonatremic control group of patients who were matched for age, sex, and diagnosis group...

Lymphocytes circulate through lymph nodes (LN) in search for antigen in what is believed to be a continuous process. Here, we show that lymphocyte migration through lymph nodes and lymph occurred in a non-continuous, circadian manner. Lymphocyte homing to lymph nodes peaked at night onset, with cells leaving the tissue during the day. This resulted in strong oscillations in lymphocyte cellularity in lymph nodes and efferent lymphatic fluid. Using lineage-specific genetic ablation of circadian clock function, we demonstrated this to be dependent on rhythmic expression of promigratory factors on lymphocytes...

Empathy is a central component of nurse-consumer relationships. In the present study, we investigated how empathy is developed and maintained when there is conflict between nurses and consumers, and the ways in which empathy can be used to achieve positive outcomes. Through semistructured interviews, mental health nurses (n = 13) and consumers in recovery (n = 7) reflected on a specific conflict situation where they had experienced empathy, as well as how empathy contributed more generally to working with nurses/consumers...

A novel class of potent PI3Kδ inhibitors with >1000-fold selectivity against other class I PI3K isoforms is described. Optimization of the substituents on a triazole aminopyrazine scaffold, emerging from an in-house PI3Kα program, turned moderately selective PI3Kδ compounds into highly potent and selective PI3Kδ inhibitors. These efforts resulted in a series of aminopyrazines with PI3Kδ IC50⩽1nM in the enzyme assay, some of the most selective PI3Kδ inhibitors published to date, with a cell potency in a JeKo-cell assay of 20-120nM...

A 17-year-old patient with GSD type 1a (von Gierke disease) was hospitalized with an extremely elevated serum lactate following an intercurrent infection and interruption of his frequent intake of carbohydrates. The patient developed shock, oliguric renal failure, and cardiorespiratory failure requiring mechanical ventilation and inotropes. At the peak of metabolic decompensation and clinical instability, serum lactate reached a level of 47.6 mmol/L which was accompanied by a severe anion gap metabolic acidosis with a pH of 6...

BACKGROUND: Comorbid depression is highly prevalent in geriatric patients and associated with functional loss, frequent hospital re-admissions, and a higher mortality rate. Cognitive behavioral psychotherapy (CBT) has shown to be effective in older depressive patients living in the community. To date, CBT has not been applied to older patients with acute physical illness and comorbid depression. OBJECTIVES: To evaluate the effectiveness of CBT in depressed geriatric patients, hospitalized for acute somatic illness...
