Reversal theory constructs and cigarette availability predict lapse early in smoking cessation

The purpose of this study was to investigate the contribution of reversal theory constructs (i.e., metamotivational states) to understanding the outcome of tempting situations thatoccur in the first 6 weeks of smoking cessation. Cessation program participants (N = 68) were interviewed about tempting situations in which they either smoked or maintained abstinence. Both independent groups and repeated measures analyses indicated that metamotivational state (serious and goal-directed vs. playful and spontaneous) and cigarette availability significantly predicted outcome. Reversal theory constructs correctly predicted outcome of the tempting episode for 70% of the subjects, while cigarette availability was an accurate predictor for 74%. Metamotivational state and cigarette availability together predicted the outcome for 89% of the subjects. ©1995 John Wiley & Sons, Inc.     

A preventive intervention for enhancing resilience among highly stressed urban children

Describes the development and evaluation of a pilot 12-session, school-based preventive intervention designed to enhance resilience among inner-city children who have experienced major life stress. Thirty-six 4th–6th grade children participated in the intervention in groups of 5–8 co-led by school personnel. The curriculum focussed on understanding feelings in oneself and others, perspective-taking, social problem-solving, dealing with solvable and unsolvable problems, and building self-efficacy and esteem. Pre-post evaluation showed significant improvement among participants on teacher-rated indices of learning problems and task orientation and on child ratings of perceived self-efficacy, realistic control attributions and anxiety. Program limitations and factors that restrict generalization are considered and new directions for program development and research are proposed.     

Ambulatory Mental Health Treatment under Universal Coverage: Policy Insights from Israel

Untested assumptions concerning ambulatory treatment have shaped mental health policies for decades. Three opinions prevail: (1) all use is alike; (2) any use leads to high use; and (3) all high use is discretionary and therefore excessive. These assumptions were tested, using data from a nationwide survey of ambulatory utilizers in Israel, a country that has universal coverage. The findings, based on detailed clinical and treatment records, challenge all three assumptions. Moreover, they document a diversity of clinical needs while also verifying substantial variations in the type, frequency, and duration of treatment provided to meet those needs. In brief, Israeli data do not confirm continuing concerns by policy makers about uncontrollable use of services with expanded mental health coverage. Special policy limitations on mental health treatment should be reconsidered in light of empirical evidence from a system without the restrictions that exist in the United States.     

Wirkung des Äthylazetatextraktes von Chrysanthemum morifolium auf Plasmodium falciparumIn Vitro

Zusammenfassung Die Wirkung des ?thylazetatextraktes von Chrysanthemum morifolium auf P. falciparum wurde in vitro untersucht. W?hrend sich die Parasit?mie bei der Kontrollgruppe bis zu 10. 90 % entwickelte, wurde bei dem mit ?thylazetatextrakt in einer Konzentration von 100 μg/ml Medium am 5. Tag der Kultur eine signifikante Hemmwirkung auf die Parasiten beobachtet. Die Parasit?mie blieb bei 1. 00 %.

Molecular basis of the functional podocin-nephrin complex: mutations in the NPHS2 gene disrupt nephrin targeting to lipid raft microdomains

Hereditary nephrotic syndrome is a heterogeneous disease, characterizedby heavy proteinuria and renal failure. Mutations of NPHS1 orNPHS2, the genes encoding for nephrin and podocin, lead to earlyonset of heavy proteinuria, and rapid progression to end-stagerenal disease, suggesting that both proteins are essential forthe integrity of the glomerular filter. Podocin is a stomatinprotein family member with a predicted hairpin-like structurelocalizing to the insertion site of the slit diaphragm of podocytes,the visceral glomerular epithelial cells of the kidney. Herewe investigate the pathomechanisms of different disease-causingpodocin mutations. We show that wild-type podocin is targetedto the plasma membrane, and forms homo-oligomers involving thecarboxy and amino terminal cytoplasmic domains. The associationof podocin with specialized lipid raft microdomains of the plasmamembrane was a prerequisite for recruitment of nephrin intorafts. In contrast, disease-causing mutations of podocin (R138Qand R138X) failed to recruit nephrin into rafts either becausethese mutants were retained in the endoplasmic reticulum (R138Q),or because they failed to associate with rafts (R138X) despitetheir presence in the plasma membrane. None of the mutants didaugment nephrin signaling, suggesting that lipid raft targetingfacilitates nephrin signaling. Our findings demonstrate thatthe failure of mutant podocin to recruit nephrin into lipidrafts may be essential for the pathogenesis of NPHS2. ^* To whom correspondence should be addressed.

Assessment of intrafamilial clinical variability of poikiloderma with neutropenia by a 10-year follow-up of three affected siblings

Clericuzio-type poikiloderma with neutropenia is a well-defined nosological entity, but despite a remarkable number of clinical reports, no long term follow-up data has been presented to date regarding patients with this rare condition.Here we describe the results of clinical follow-up of three siblings, one male (Patient 1) and two females (Patients 2 and 3), subsequent to their first clinical and then molecular diagnosis of Clericuzio-type poikiloderma with neutropenia syndrome due to mutation of USB1gene. Patient 1 always expressed the most severe phenotype, while patients 2 and 3 showed an intermediate and mild phenotype, respectively, as observed since their first clinical evaluation. None of the patients developed skin cancer and/or myelodysplastic disorders considering the peripheral haematological findings. Lens opacity, never reported before, was found in two of the three patients.The long term follow-up observations confirm the stability over time of the pronounced intra-familial heterogeneity of clinical manifestations observed prior to and upon molecular diagnosis. We conclude that prolonged follow-up is an adjunct tool to monitor intra-familial variability of PN clinical spectrum which may favour surveillance of more serious complications of the disease among siblings, when a patient-specific clinical expressivity is present.
