Atopic dermatitis incidence and risk factors in young adults in Castellon (Spain): A prospective cohort study

INTRODUCTION: There are few atopic dermatitis (AD) incidence cohort studies in young adults, the etiology of this disease remains obscure, and AD risk factors in adults are not well understood. The objective of this study was to estimate AD ten-year incidence and prevalence in a cohort of adolescent aged 14-16 at inception in Castellon province in Valencia Region, Spain and describe related risk factors. MATERIAL AND METHODS: From 2002 to 2012, a population-based prospective cohort study was carried out. Questionnaires from the International Study of Asthma and Allergies in Childhood (ISAAC) were used with an additional questionnaire for related factors completed by participants and their parents, respectively, in 2002. In 2012 the same questionnaires were completed by the participants' through a telephone interview, and incidence and prevalence of AD were estimated. Directed acyclic graphs, Poisson regression and inverse probability weighted regression adjustment were used. RESULTS: The participation rate was 79.5% (1435/1805) with AD lifetime prevalence of 34.9% and AD incidence of 13.5 per 1000 person years. Females presented higher prevalence and incidence than males. After adjustment significant risk factors were being female, history of asthma or allergic rhinitis, family history of AD, history of respiratory infections, history of bronchitis, history of pneumonia, history of sinusitis, and birthplace outside Castellon province. The highest AD population attributable risks were female, 30.3%, and history of respiratory infections 15.3%. Differences with AD childhood risk factors were found. CONCLUSIONS: AD incidence in our cohort was high and several risks factors were related to AD

Vitamin D status and latent tuberculosis infection: conversion in nursing homes, Spain.

OBJECTIVE: To examine the potential association between vitamin D (VitD) deficiency and latent tuberculosis infection (LTBI) and its effect on TB infection conversion (TBIC) incidence.MATERIAL AND METHODS: We carried out a cross-sectional and prospective cohort study of nine pulmonary TB cases that occurred in 2015-2016 in five nursing homes and one mental disability institution in Castellon, Spain. QuantiFERON®-TB Gold and the tuberculin skin test were used to detect LTBI and TBIC, respectively. Serum 25-hydroxyvitamin D was measured using chemiluminescence immunoassay. Poisson regression and inverse probability weighting were used for statistical analyses.RESULTS: The study included 448 residents, 341 staff members with 48 relatives of TB cases (participation rate 82%): of these, respectively 122 (27.2%), 37 (10.9%) and 7 (14.6%) were LTBI-positive; and respectively 22 (7.7%), 10 (3.8%) and 1 (3.7%) were TBIC-positive. LTBI was not associated with VitD status. Severe VitD deficiency (SVDD; defined as VitD level < 10 ng/ml), found in 45.1% of residents, as well as VitD levels of <30 ng/ml (aRR 10.41 95% CI 1.48-73.26), were associated with increased TBIC risk (adjusted relative risk [aRR] 12.1, 95% CI 1.51-97.10), suggesting SVDD as a threshold effect. CONCLUSION: Severe VitD deficiency is a TBIC risk factor.

Incidence of asthma in young adults from Castellon, Spain: A prospective cohort study

Background: The objective was to estimate the incidence of asthma in young adults from 13-15 years old to 23-25 years old, and associated factors. Methods: In 2012, a population-based prospective cohort study was carried out in Castellon from the cohort who had participated in the International Study of Asthma and Allergy in Childhood in 1994 and 2002. A telephone survey was undertaken using the same questionnaires. A new case of asthma was defined as a participant free of the disease in 2002 who suffered asthma, was diagnosed with asthma, or took medications against asthma based on self-report from 2002 to 2012. Results: The mean age of participants was 24.9 ± 0.6 with a follow-up of 79.1%. Asthma cumulative incidence was 3.4%: 44 new cases occurred among 1280 participants. The incidence was higher in females than males with relative risk (RR) =2.02 (95% confidence interval [CI] 1.1-3.8). A significant decrease of asthma incidence density was observed (8.2 cases to 3.5 cases per 1000 person/year). Factors associated with the incidence of asthma were allergic rhinitis (RR = 4.05; 95% CI 1.7-9.6), bronchitis (RR = 2.13; 95% CI 1.0-4.5), mother's age at time of birth (RR=0.87; 95% CI 0.8-0.9) and a pet other than a dog or cat (RR = 0.42; 95% CI 0.2-0.9). For gender, some variations in the risk factors were observed. Conclusions: A significant decrease in the incidence of asthma was observed. Several risk and protective factors were found (AU)

Incidence of allergic rhinitis in a cohort of young adults from 13-15 years old to 23-25 years old in Castellon (Spain)

BACKGROUND: The objective of this study was to estimate the incidence of Allergic Rhinitis (AR) in young adults and its risk or protective factors. METHODS: A population-based prospective cohort study was carried out in 2012. The cohort participated in the International Study of Asthma and Allergy in Childhood in Castellon in 1994 and 2002. A telephone survey was conducted using the same questionnaires. A new case of AR was defined as the participants free of the disease in 2002, who self-reported suffering from AR or taking medications for AR in the period 2002-2012. RESULTS: Of the 1805 schoolchildren in the cohort in 2002, 1435 young adults (23-25 years old) participated (follow-up 79.1%) in 2012; 743 were female and 692 male; their mean age was 24.9±0.6 years. Two hundred new cases of AR occurred in 1259 participants free of the disease with an incidence of 17.3 per 1000 person-years, and the incidence increased from 2002 (RR=1.42; 95% CI 1.15-1.75). The risk factors of AR adjusted by age and gender were sinusitis (RR=1.77; 95% CI 1.16-2.68), atopic dermatitis (RR=1.51; 95% CI 1.11-2.06) and constant exposure to truck traffic (RR=1.88; 95% CI 1.12-3.17). For male participants, the risk factors were asthma, sinusitis and atopic dermatitis, and for females bronchitis was a risk factor and presence of older siblings a protective factor. CONCLUSIONS: An increase in AR incidence was observed. Sinusitis, atopic dermatitis and constant exposure to truck traffic were the risk factors of the AR with some differences by gender

Adsorbed states of chlorophenol on Cu(110) and controlled switching of single-molecule junctions.

A molecular junction of substituted benzene (chlorophenol) is fabricated and controlled by using a scanning tunneling microscope (STM). Prior to the junction formation, the bonding geometry of the molecule on the surface is characterized by STM and electron energy loss spectroscopy (EELS). EELS shows that the OH group of chlorophenol is dissociated on Cu(110) and that the molecule is bonded nearly flat to the surface via an O atom, with the Cl group intact. We demonstrate controlled contact of an STM tip to the "available" Cl group and lift-up of the molecule while it is anchored to the surface via an O atom. The asymmetric bonding motifs of the molecule to the electrodes allow for reversible control of the junction.

Correlation between external exposure and activity in patients undergoing 131I thyroid cancer therapy.

The uptake and clearance of 131I activity for inpatients undergoing cancer therapy were determined from routine external dose survey measurements. A bi-exponential behavior was found, with the two time constants representing the iodine dynamics in the thyroid on one hand and in the rest of the body on the other. The external dose at 1 m from the patient was correlated to the activity in the thyroid remnant and inside the body, the averaged value being 52.8 +/- 11.4 microSv GBq(-1) h(-1). The temporal evolution of activity in the body, the urinary system and the thyroid remnant area were determined taking into account the clearance from thyroid and whole body (effective retention constants averages 0.23 +/- 0.14 d(-1) and 1.46 +/- 0.34 d(-1)) and the uptake in thyroid (3.15 +/- 3.36%). Applications of this study in the public and environmental radiation protection areas are presented.

Rotación de buprenorfina transdérmica a oxicodona en un caso de delirium / No disponible

La prescripción de buprenorfina en presentación transdérmica para el tratamiento del dolor crónico de intensidad moderada a severa, ha presentado un aumento importante en la atención primaria de la región sanitaria de Lleida. En los últimos años ha sido el segundo fármaco opioide mayor prescrito, en cuanto a Dosis Diarias Definidas (DDD). Oxicodona es un fármaco opioide agonista puro que presenta una excelente biodisponibilidad, así como menos efectos secundarios que morfina, motivo por el cual puede ser considerado una alternativa a esta cuando se presenta intolerancia, efectos adversos o falta de efecto analgésico. El delirium resulta de la interacción de ciertas condiciones del paciente, que le predisponen o le hacen más vulnerable, y de algún factor precipitante, que puede estar relacionado con alguna enfermedad o el uso de fármacos, entre otros. Presentamos el caso de una paciente de 75 años de edad diagnosticada de carcinoma epidermoide vulvar, con progresión locorregional, que mientras estaba siendo tratada con buprenorfina transdérmica en su domicilio, presentó un deterioro cognitivo y funcional severos coincidiendo con la escalada de dosis analgésicas por mal control del dolor (AU)

The prescription of transdermal buprenorphine for treating moderate to severe chronic pain has shown an important increment in the primary health care of the sanitary region of Lleida being, on 2005, the second strong opioid in Defined Daily Dose (DDD) prescribed. Oxycodone is a pure agonist opioid that presents an excellent bioavailability and less adverse effects than morphine. For that reason can be considered a safe alternative when intolerance, adverse effects or lack of analgesia is present. Delirium results from the interaction of certain conditions of the patient, leading them to a more vulnerable state, and of some precipiting factors, that can be related to some disease or drug use. We present a case of a 75 years old lady diagnosed of epidermoid carcinoma of vagina with regional spreading. While she was treated at home with transdermal buprenorphine, she presented with a cognitive and functional impairment due to the increasing analgesic doses due to incomplete pain relief (AU)

Analysis of the effects of daunorubicin and WP631 on transcription.

The proficiency with which anthracyclines and other DNA-binding drugs target certain sequences in eukaryotic promoters offers a potential approach to interfere with the mechanisms that regulate gene expression in tumor cells. An in vitro transcription assay has been used to compare the ability of the bisintercalating anthracycline WP631 and the monointercalating anthracycline daunorubicin in terms of their ability to inhibit initiation of transcription of the adenovirus major late promoter linked to a G-less transcribed DNA template. Both drugs inhibit basal transcription by RNA polymerase II. However, WP631 is approximately 15 times more efficient at inhibiting transcription initiation from an adenovirus promoter containing an upstream Sp1-protein binding site. The differences in the ability of each drug to inhibit transcription initiation appear to be related to the competition between Sp1 and the anthracyclines for binding to the same site. To see whether WP631's strong effect on transcription can also be observed in cells, we compared the effects of WP631 and other anthracyclines on the transcription of the c-myc gene, which promoter contains Sp1 binding sites. The resulting data suggest that WP631 might circumvent some kinds of tumor resistance at rather low drug concentrations, inhibit c-myc expression in some cell lines, and exert its antitumoral effect by inducing apoptosis.

The unr gene: evolutionary considerations and nucleic acid-binding properties of its long isoform product.

The unr transcription unit is located just upstream of the N-ras gene in the genome of mammals, in which unr, like N-ras, is ubiquitously expressed. To determine at what point in evolution the unr/N-ras linkage was created, analysis of nucleic acids by Southern and Northern blotting was performed, allowing us to track the presence of the unr gene to the start of vertebrate evolution and the unr/N-ras linkage to the time at which the reptilian and bird lines diverged. We have investigated, with specific anti-unr antibodies, a potential relation between unr protein levels and cellular processes in which N-ras is implicated. A positive correlation in the proliferation of 3T3 cells, but not differentiation of PC12 cells induced by nerve growth factor (NGF), was found. To study the nucleic acid-binding properties of unr, a protein with multiple repeats of a nucleic acid-binding motif, we expressed the long splicing isoform in a eukaryotic cell line and purified it in native form. The results obtained-a high affinity of unr for single-stranded DNA and RNA and lower affinity for double-stranded DNA without regard to nucleic acid sequence, and its intracellular localization in both the nuclear and non-nuclear compartments, together with its ubiquious expression in mammalian tissues-provide molecular information about the function of one of the closest gene tandems in mammalian cells (unr-N-ras).

Isolation of high molecular weight DNA for reliable genotyping of transgenic mice.

A fast and reliable method for the PCR characterization of DNA from mouse toes is described. The toes biopsied to tag the mice are incubated for 2 h in proteinase K and heated for 15 min at 95 degrees C. This DNA solution is directly used as a template for PCR amplification. The same procedure can be used for PCR analysis of DNA from other tissues in adult mice, mouse embryos and cultured cells. Because of minimal tissue manipulation, high-quality and high-molecular-weight DNA (fragments larger than 100-200 kb) is isolated. This procedure is performed in a single tube and requires no organic solvent extraction or centrifugation, allowing the isolation of high-molecular-weight DNA suitable for PCR amplification in a fast and reproducible way. Only the tissue excised during mice tagging is used and a large number of animals can be quickly and simultaneously analyzed as required to maintain a transgenic mice colony. In addition, this rapid and efficient procedure represents an alternative to other methods in which, in our experience, inhibition of the PCR amplification occurs when DNA from tail tissues is used.

Laparoscopy-assisted vaginal hysterectomy compared with abdominal hysterectomy.

The first 150 consecutive laparoscopic vaginal hysterectomy (LVH) cases done by Creighton University faculty members at Mercy Hospital, Council Bluffs, Iowa and at St Joseph Hospital, Omaha, Nebraska were compared with 194 abdominal hysterectomies (AHs) for benign or noninvasive disease. The results indicate that LVH can be accomplished with low morbidity, low length of stay, and with less patient discomfort than experienced by patients who undergo AH.
