Expressions of hope in cystic fibrosis patients: a comparison with the general population

PURPOSE: Hope was evaluated in Norwegian patients with cystic fibrosis (CF). PARTICIPANTS: The subjects were 87 Norwegian adults with CF and a control group of 1020 from the general population (GP). METHODS: Subjects completed a questionnaires that included the Herth Hope Index and demographic variables. Data on health-related variables were collected for the CF group. RESULTS: The mean age of the CF patients was 29 years (range 18-54). Almost 50% had a forced expiratory volume for one second percent predicted (FEV1%) below 50%, and 21% reported perceiving being in a bad phase of the disease. The CF patients reported lower (poorer) levels of hope than the GP sample, especially for the item scared about the future. However, they scored higher on inner strength and were younger, more often living alone, unmarried, not in paid work, but with similar educational levels. Levels of hope increased with increasing age in the CF patients but decreased for the GP subjects. The health variable that most affected hope in the CF sample was pulmonary function, not the presence of asthma or chronic lung infections. CONCLUSIONS: Persons growing up with CF experience many challenges. CF patients expressed slightly lower levels of hope and were more scared of the future. They scored higher on inner strength than the general population.     

The role of the polio virus receptor and the herpesvirus entry mediator B genes for the development of MS

Multiple sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system (CNS). Although the cause of MS is still uncertain, it is well accepted that both genetic and environmental factors are important for the development of disease. In this study, we focused on the Polio Virus Receptor (PVR) and Herpesvirus entry mediator B (HVEB) receptor genes, which are located on chromosome 19q13, a region previously linked to MS. Both receptors are expressed in the brain and immune system and play an important role for inter-cellular adhesion and entry of neurotropic viruses to the brain. We identified four new polymorphisms in the PVR gene, which were located in the promoter region and three different exons. All exonic polymorphisms altered the amino acid sequence of the receptor. No new polymorphisms were found in the HVEB gene, but we confirmed a previously identified intronic polymorphism. We analyzed the frequency of the polymorphisms by RFLP analysis in sporadic MS patients, MS families, and healthy controls and determined the surface expression of HVEB and PVR on peripheral blood monocytes. We did not find differences in the frequency of the polymorphisms or surface expression between MS patients and controls. Overall, our findings do not support a role of HVEB and PVR genes in the development of MS.     

Bioequivalence determination of topical ketoprofen using a dermatopharmacokinetic approach and excised skin penetration

Ketoprofen is a photolabile drug. The aim of the present study was to compare the bioavailability of ketoprofen in a photo-stabilised formulation with a gel without photoprotection using a new dermatopharmacokinetic tape-stripping model and an established ex vivo penetration method using human skin. Analyses of the stratum corneum showed that during the first 45 min about 12 microg/cm2 ketoprofen was absorbed into the skin from the formulations. The area under the ketoprofen content-time curve (AUC0-6 h) for the ratio photo-stabilised gel/transparent gel was 73% with a 90% confidence interval (CI) 65-83. The rate of penetration of ketoprofen through isolated skin was approximately 0.2 microg/cm2 h for both formulations. AUC0-36 h for the ratio was 84% with 90% CI 64-105. Thus, the two methods did not disagree in terms of relative efficacy of the two gels. However, the difference obtained in vivo was statistically significant, whereas no significant data arise from the ex vivo study. Comparing the amount of ketoprofen in the skin after 45 min with the amount penetrated through the excised skin during 36 h, suggests a change in the thermodynamic activity of ketoprofen during the exposure. A supersaturated formulation may well have been formed initially due to evaporation of ethanol.     

A comparison of sexual behaviour and attitudes of healthy adolescents in a Danish high school in 1982, 1996, and 2001

AIM: To assess changes in sexual behaviour among students at a high school in Denmark from 1982 to 2001. METHODS: An anonymous self-administered questionnaire was used to compare data from three identical cross-sectional surveys performed in 1982, 1996, and 2001. RESULTS: Girls: More girls reported their first sexual intercourse before their 16th birthday in 2001 (42%) than in 1996 (29%) In 1982 it was also 42% (Chi-square for trend: p = 0.003). Fewer girls with no regular partner used condoms for their personal protection in 2001 (2%) than in 1996 (9%) and 1982 (0%) (Chi-square for trend p = 0.016). The proportion of girls with no regular partner who considered protection from sexually transmitted disease important for their choice of contraception was 39% in 2001 compared with 71% in 1996 and only 10% in 1982 (Chi-square for trend: p < 0.0001).Boys: More boys reported sexual debut before their 16th birthday in 2001 (40%) than in 1996 (37%) and 1982 (24%) (Chi-square for trend: p = 0.023). For boys with no regular partner, condom was preferred for personal protection by 85% in 2001, 91% in 1996 and 61% in 1982 (Chi-square for trend p = 0.007). Protection against sexually transmitted infection declined, especially among boys with no regular partner, from 51% in 2001 to 72% in 1996 and 21% in 1982 Chi-square for trend: p < 0.0001).The tendency towards earlier sexual debut and less use of safe sex practices to protect against sexually transmitted infections (STI) was accompanied by a rise in the number of detected STIs during this period. CONCLUSIONS: The period from 1982 to 1996 during which sexual attitudes were directed toward safer sex seems to have given way to a reverse trend in the period from 1996 to 2001. These findings may have significant implications for health care authorities organising preventive strategies for healthy adolescents.     

Women's experiences of the gynecologic examination: factors associated with discomfort

BACKGROUND: The aim of this study was to evaluate how women experience the gynecologic examination and to assess possible factors associated with experiencing discomfort during the gynecologic examination. METHODS: Consecutive patients visiting the Department of Obstetrics and Gynecology at Glostrup County Hospital, Denmark, were invited to participate in the study, and received a postal questionnaire that included questions about the index visit, obstetric and gynecologic history and sexual abuse history. The response rate was 80% (n = 798). The degree of discomfort during the gynecologic examination was indicated on a scale from 0 to 10. Experiencing discomfort was defined as a score of 6 or more, based on the 75th percentile. RESULTS: Discomfort during the gynecologic examination was strongly associated with a negative emotional contact with the examiner and young age. Additionally, dissatisfaction with present sexual life, a history of sexual abuse and mental health problems such as depression, anxiety and insomnia were significantly associated with discomfort. CONCLUSION: The emotional contact between patient and examiner seemed to have great importance when focusing on discomfort during the gynecologic examination. Furthermore, we found that discomfort was associated with a number of factors that are seldom known to the gynecologists, such as sexual abuse history, mental health problems and patients' sexual life. Gynecologists need to focus on the emotional contact and to reevaluate issues for communication before the examination.     

Modern cleanroom clothing systems: people as a contamination source

Today, clothing and clothing systems for cleanrooms are mainly tested with regard to material properties such as particle generation, particle filtration, and resistance to wear. The dispersal chamber or "body-box" has been used for studying the protective efficacy of clothing systems in use, for example by Hoborn in 1981 (1) and Whyte and Bailey in 1985. A modified dispersal chamber has recently been installed at KTH. Tests and comparative studies have been performed in the dispersal chamber on selected clothing systems. The latest tests have been performed in two parts. In Part 1, each person performed 12 sequences dressed in new, modern cleanroom clothing systems with small variations, such as with and without goggles, different face masks, and different sizes of hoods. In Part 2, each person performed six test sequences with new, modern cleanroom clothing systems with variations in fabrics, and as a comparison, two sequences with pharmaceutical clothing system and surgical clothing system, respectively. The results are given in total number of airborne particles (> or = 0.5 microm per cubic meter) and airborne aerobic CFU per cubic meter. Statistical evaluations of the results have been performed. The source strengths of the contamination source people wearing modern cleanroom clothing systems have been estimated.
