Quality of general movements in preterm infants with transient periventricular echodensities

By means of sequential videotape recordings, the relevance of the quality of general movements for neurological outcome was determined in a group of 21 appropriate-for-gestational-age preterm infants with transient periventricular echodensities of variable localization and duration and in 6 infants without echodensities. Echodensities, especially in the parieto-occipital area, affected the quality of general movements. Echodensities persisting beyond 14 d were associated with abnormal general movements; infants with echodensities up to 14 d had either normal or abnormal general movements. The developmental course of movement quality was correlated to neurological outcome (p < 0:005): normal outcomes were found in 11/12 infants with normal general movements throughout and in 9/11 infants with transient abnormal general movements; all 4 infants with persistent abnormal general movements had impaired outcomes. In infants with transient echodensities, longitudinal assessment of the quality of general movements helps to determine if there is brain dysfunction, either transient or persistent, and identifies infants at risk for impaired neurological outcomes.     

Evaluation of 2 brief instruments and a food-frequency questionnaire to estimate daily number of servings of fruit and vegetables

BACKGROUND: Measurement of fruit and vegetable intake is important in the surveillance of populations and in epidemiologic studies that examine the relations between diet and disease. Some situations require the use of brief dietary assessment tools. OBJECTIVE: Our objective was to evaluate the performance of 2 brief dietary assessment instruments, a 7-item standard screener and a new 16-item screener, and a complete food-frequency questionnaire (FFQ) in measuring total fruit and vegetable consumption. DESIGN: About 800 men and women from the National Institutes of Health-AARP Diet and Health Study completed an FFQ, 1 of the 2 screeners, and two 24-h dietary recalls. Fruit and vegetable intakes as measured by each screener and the FFQ were compared with estimated true usual intake by using a measurement-error model. RESULTS: Median daily servings of fruit and vegetables were underestimated by both screeners. The estimated agreement between true intake and the screener was higher for the new screener than for the standard screener and was higher for women than for men. The estimated agreement between true intake and the FFQ was higher than that for both screeners. Attenuation coefficients for the FFQ and screeners were comparable. CONCLUSIONS: For estimating median intakes of fruit and vegetables and the prevalence of recommended intakes being met, the use of screeners without appropriate adjustment is suboptimal. For estimating relative risks in the relations between fruit and vegetable intake and disease, screeners and this FFQ are similar in performance.     

Fruit and vegetable intake in the United States: the baseline survey of the Five A Day for Better Health Program

PURPOSE. The purpose of the Five A Day Baseline Survey was to assess fruit and vegetable intake and associated factors among US adults. DESIGN. Questionnaires querying frequency of intake of 33 fruits and vegetables, as well as demographics, attitudes, and knowledge related to fruits and vegetables were administered by telephone. SETTING. The study was a nationally representative random digit dial survey conducted by telephone in the summer of 1991; response rate was 42.8%. SUBJECTS. Respondents were 2811 US adults (including an oversample of African-Americans and Hispanics). MEASURES. Mean and median self-reported intakes of fruits and vegetables were calculated. Estimated servings per week were adjusted on the basis of responses to summary questions regarding overall fruit and vegetable intakes. RESULTS. Median intake of fruits and vegetables was 3.4 servings per day. Linear regressions (accounting for no more than 10% of the variation) showed that education, income, and smoking status were predictors of fruit and vegetable intake and that intake increased with education, income, and nonsmoking status. Women had higher intakes than men at all ages; these differences between men and women increased with age. Fruit and vegetable intakes increased with age for whites and Hispanics, but not for African-Americans. CONCLUSIONS. Fruit and vegetable intake among adults in the United States is lower than the recommended minimum of five daily servings. These data will be useful in targeting campaign efforts and in assessing progress of the Five A Day for Better Health Program.

The cost of hospital-related care of patients with psoriasis in Italy based on the AISP study

The objective of this study was to assess the cost of caring for patients with psoriasis in Italy according to the AISP study (Associazione Italiana Studi Psoriasi or Italian Association for Studies on Psoriasis), involving 104 university and hospital centres and 7992 patients in 1994. The mean yearly cost of care for a single patient was calculated at 905 Euros. Hospitalization accounted for more than four-fifths of the costs, therapy for about one-eighth (systemic therapies were the most expensive) and office visits and day hospitals for the remainder. In our study series less than 20% of patients accounted for more than 90% of the total costs.     

FAT ARMS,OBESITY AND CHOICE OF BLOOD PRESSURE CUFF SIZE IN DIABETIC PATIENTS

SUMMARY Four hundred consecutive diabetic patients had their mid-arm circumference (AC) measured and body mass index (BMI) calculated to determine the proportion of an unselected clinic group who would require a larger than standard adult blood pressure (BP) cuff and whether or not BMI could be used to predict AC and hence choice of appropriate BP cuff size. More than 75% of both men and women had an AC ≥29cm, justifying a larger than standard adult cuff for their BP measurement. When patients were classified according to their BMI, at least 80% with a BMI ≥30 and more than 70% with a BMI of 25-29 had a measured AC ≥29cm, while less than a third of patients with a BMI ≥25 had an AC ≥29cm. These results indicate that, in a diabetic clinic, most patients with a BMI ≥25 are likely to require an alternative adult BP cuff if their blood pressure is to be measured precisely.     

A cytokine receptor gene cluster in the X-Y pseudoautosomal region?

The receptors for interleukin-3 (IL-3), IL-5, and granulocyte- macrophage colony-stimulating factor (GM-CSF) are heterodimers comprised of ligand specific alpha chains and a common beta chain. The genes encoding the IL-5 receptor alpha chain and the common beta chain reside on chromosome 3 and 22 respectively, while the GM-CSF receptor alpha chain gene (CSF2RA) has been mapped to the pseudoautosomal region (PAR) of the sex chromosomes, which is a 2.6-Mb stretch of homologous sequence at the tips of the short arms within which a single obligatory recombination occurs during male meiosis. We have mapped the gene encoding the IL-3 receptor alpha chain (IL3RA) to the sex chromosomes by polymerase chain reaction (PCR) analysis of human-mouse or human- chinese hamster cell hybrids, and to Yp13.3 and Xp22.3 using fluorescence in situ hybridization. To explore the possibility that IL3RA is located within the pseudoautosomal region we screened the Centre d'Etude du Polymorphisme Humain (CEPH) pedigrees for an informative-restriction fragment-length polymorphism (RFLP) that showed male meiotic recombination. Two informative CEPH pedigrees were identified that displayed this phenomenon, confirming the psuedoautosomal location of IL3RA. Using long-range restriction mapping we have found that IL3RA maps to the same 190-kb restriction fragment as CSF2RA, suggesting that a cytokine receptor gene cluster may reside in the PAR.     

Procalcitonin (PCT) and C-reactive Protein (CRP) as severe systemic infection markers in febrile neutropenic adults

Background  

Procalcitonin (PCT) is an inflammatory marker that has been used as indicator of severe bacterial infection. We evaluated the concentrations of PCT as a marker for systemic infection compared to C-reactive protein (CRP) in patients neutropenic febrile.
