Factors associated with good self-rated health and quality of life in subjects with self-reported COPD

Background: Recent guidelines for chronic obstructive pulmonary disease (COPD) state that COPD is both preventable and treatable. To gain a more positive outlook on the disease it is interesting to investigate factors associated with good, self-rated health and quality of life in subjects with self-reported COPD in the population. Methods: In a cross-sectional study design, postal survey questionnaires were sent to a stratified, random population in Sweden in 2004 and 2008. The prevalence of subjects (40–84 years) who reported having COPD was 2.1% in 2004 and 2.7% in 2008. Data were analyzed for 1475 subjects. Regression models were used to analyze the associations between health measures (general health status, the General Health Questionnaire, the EuroQol five-dimension questionnaire) and influencing factors. Results: The most important factor associated with good, self-rated health and quality of life was level of physical activity. Odds ratios for general health varied from 2.4 to 7.7 depending on degree of physical activity, where subjects with the highest physical activity level reported the best health and also highest quality of life. Social support and absence of economic problems almost doubled the odds ratios for better health and quality of life. Conclusions: In this population-based public health survey, better self-rated health status and quality of life in subjects with self-reported COPD was associated with higher levels of physical activity, social support, and absence of economic problems. The findings indicated that of possible factors that could be influenced, promoting physical activity and strengthening social support are important in maintaining or improving the health and quality of life in subjects with COPD. Severity of the disease as a possible confounding effect should be investigated in future population studies

Evaluation of a Parental Questionnaire to Identify Atopic Dermatitis in Infants and Preschool Children

Aim. To develop and validate a questionnaire for detecting atopic dermatitis in infants and small children from the age of 2 months. Methods. Parents to 60 children answered a written questionnaire prior to a physical examination and individual semistructured interview. Qualitative and quantitative analyses of validity, sensitivity, specificity, and predictive values of the questionnaire were performed. Results. A total of 27 girls and 33 boys, aged 2 to 71 months, 35 with and 25 without physician-diagnosed eczema, participated. Validation of the questionnaire by comparisons with physicians' diagnoses showed a sensitivity of 0.91 (95% CI 0.77–0.98) and a specificity of 1 (95% CI 0.86–1). Conclusions. Three questions in a parental questionnaire were sufficient for diagnosing eczema in infants and small children

Prenatal phthalate exposures and anogenital distance in Swedish boys

BACKGROUND: Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and in a large number of consumer products. Because of reported health risks, diisononyl phthalate (DiNP) has been introduced as a replacement for di(2-ethylhexyl) phthalate (DEHP) in soft PVC. This raises concerns because animal data suggest that DiNP may have antiandrogenic properties similar to those of DEHP. The anogenital distance (AGD)-the distance from the anus to the genitals-has been used to assess reproductive toxicity. OBJECTIVE: The objective of this study was to examine the associations between prenatal phthalate exposure and AGD in Swedish infants. METHODS: AGD was measured in 196 boys at 21 months of age, and first-trimester urine was analyzed for 10 phthalate metabolites of DEP (diethyl phthalate), DBP (dibutyl phthalate), DEHP, BBzP (benzylbutyl phthalate), as well as DiNP and creatinine. Data on covariates were collected by questionnaires. RESULTS: The most significant associations were found between the shorter of two AGD measures (anoscrotal distance; AGDas) and DiNP metabolites and strongest for oh-MMeOP [mono(4-methyl-7-hydroxyloctyl) phthalate] and oxo-MMeOP [mono-(2-ethyl-5-oxohexyl) phthalate]. However, the AGDas reduction was small (4%) in relation to more than an interquartile range increase in DiNP exposure. CONCLUSIONS: These findings call into question the safety of substituting DiNP for DEHP in soft PVC, particularly because a shorter male AGD has been shown to relate to male genital birth defects in children and impaired reproductive function in adult males and the fact that human levels of DiNP are increasing globally

Intravenous versus oral etoposide : efficacy and correlation to clinical outcome in patients with high-grade metastatic gastroenteropancreatic neuroendocrine neoplasms (WHO G3)

High-grade gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs, G3) are aggressive cancers of the digestive system with poor prognosis and survival. Platinum-based chemotherapy (cisplatin/carboplatin + etoposide) is considered the first-line palliative treatment. Etoposide is frequently administered intravenously; however, oral etoposide may be used as an alternative. Concerns for oral etoposide include decreased bioavailability, inter-and intra-patient variability and patient compliance. We aimed to evaluate possible differences in progression-free survival (PFS) and overall survival (OS) in patients treated with oral etoposide compared to etoposide given as infusion. Patients (n = 236) from the Nordic NEC study were divided into three groups receiving etoposide as a long infusion (24 h, n = 170), short infusion (= 5 h, n = 33) or oral etoposide (n = 33) according to hospital tradition. PFS and OS were analyzed with Kaplan-Meier (log-rank), cox proportional hazard ratios and confidence intervals. No statistical differences were observed in PFS or OS when comparing patients receiving long infusion (median PFS 3.8 months, median OS 14.5 months), short infusion (PFS 5.6 months, OS 11.0 months) or oral etoposide (PFS 5.4 months, OS 11.3 months). We observed equal efficacy for the three administration routes suggesting oral etoposide may be safe and efficient in treating high-grade GEP-NEN, G3 patients scheduled for cisplatin/carboplatin + etoposide therapy.Peer reviewe

Expression of p53 protein in high-grade gastroenteropancreatic neuroendocrine carcinoma

Background Gastroenteropancreatic neuroendocrine carcinomas (GEP-NECs) are aggressive, rapidly proliferating tumors. Therapeutic response to current chemotherapy regimens is usually short lasting. The aim of this study was to examine the expression and potential clinical importance of immunoreactive p53 protein in GEP-NEC. Materials and methods Tumor tissues from 124 GEP-NEC patients with locally advanced or metastatic disease treated with platinum-based chemotherapy were collected from Nordic centers and clinical data were obtained from the Nordic NEC register. Tumor proliferation rate and differentiation were re-evaluated. All specimens were immunostained for p53 protein using a commercially available monoclonal antibody. Kaplan-Meier curves and cox regression analyses were used to assess progression-free survival (PFS) and overall survival (OS). Results All tumor tissues were immunoreactive for either one or both neuroendocrine biomarkers (chromogranin A and synaptophysin) and Ki67 index was >20% in all cases. p53 immunoreactivity was only shown in 39% of the cases and was not found to be a prognostic marker for the whole cohort. However, p53 immunoreactivity was correlated with shorter PFS in patients with colorectal tumors (HR = 2.1, p = 0.03) in a univariate analysis as well as to poorer PFS (HR = 2.6, p = 0.03) and OS (HR = 3.4, p = 0.02) in patients with colorectal tumors with distant metastases, a correlation which remained significant in the multivariate analyses. Conclusion In this cohort of GEP-NEC patients, p53 expression could not be correlated with clinical outcome. However, in patients with colorectal NECs, p53 expression was correlated with shorter PFS and OS. Further studies are needed to establish the role of immunoreactive p53 as a prognostic marker for GEP-NEC patients.Peer reviewe

Varför skadas barn som de gör?

Denna artikel handlar om varför riskerna för barn att skadas av olyckor är större än för vuxna. I korthet handlar detta om att: • Barns fysik och motorik är under ständig utveckling• Vuxna ofta misstar sig på barns utvecklingsnivå • Barnets kropp är känsligare för skador än den vuxnes • Det mesta i omgivningen är konstruerat för vuxna• Barn har liten kontroll över sin omgivande miljö • Barns åsikter sällan tas tillvara i planering
