Percutaneous coronary interventions in Europe: prevalence, numerical estimates, and projections based on data up to 2004

AIMS: A registry mandated by the European Society of Cardiology collects data on trends in interventional cardiology within Europe. Special interest focuses on relative increases and ratios in new techniques and their distributions across Europe. We report the data through 2004 and give an overview of the development of coronary interventions since the first data collection in 1992. METHODS AND RESULTS: Questionnaires were distributed yearly to delegates of all national societies of cardiology represented in the European Society of Cardiology. The goal was to collect the case numbers of all local institutions and operators. The overall numbers of coronary angiographies increased from 1992 to 2004 from 684 000 to 2 238 000 (from 1250 to 3930 per million inhabitants). The respective numbers for percutaneous coronary interventions (PCIs) and coronary stenting procedures increased from 184 000 to 885 000 (from 335 to 1550) and from 3000 to 770 000 (from 5 to 1350), respectively. Germany was the most active country with 712 000 angiographies (8600), 249 000 angioplasties (3000), and 200 000 stenting procedures (2400) in 2004. The indication has shifted towards acute coronary syndromes, as demonstrated by rising rates of interventions for acute myocardial infarction over the last decade. The procedures are more readily performed and perceived safer, as shown by increasing rate of "ad hoc" PCIs and decreasing need for emergency coronary artery bypass grafting (CABG). In 2004, the use of drug-eluting stents continued to rise. However, an enormous variability is reported with the highest rate in Switzerland (70%). If the rate of progression remains constant until 2010 the projected number of coronary angiographies will be over three million, and the number of PCIs about 1.5 million with a stenting rate of almost 100%. CONCLUSION: Interventional cardiology in Europe is ever expanding. New coronary revascularization procedures, alternative or complementary to balloon angioplasty, have come and gone. Only stenting has stood the test of time and matured to the default technique. Facilitated access to PCI, more complete and earlier detection of coronary artery disease promise continued growth of the procedure despite the uncontested success of prevention.

Long-term effects of supervised exercise training on walking capacity and quality of life in patients with intermittent claudication

Supervised exercise training has been shown to improve walking capacity in several studies of patients with intermittent claudication. However, data on long-term outcome are quite limited. The aim of this prospective study was to evaluate long-term effects of supervised exercise training on walking capacity and quality of life in patients with intermittent claudication. Patients and methods: Sixty-seven consecutive patients with intermittent claudication who completed a supervised 12-week exercise training program were asked for follow up evaluation 39 +/- 20 months after program completion. Pain-free walking distance (PWD) and maximum walking distances (MWD) were assessed by treadmill test and several questionnaires. Results: Forty (60%) patients agreed to participate, 22 (33%) refused participation, and 5 (7%) died during follow-up. PWD and MWD significantly improved at completion of 12-weeks supervised exercise training as compared to baseline (PWD 114 +/- 100 vs. 235 +/- 248, p = 0.002; MWD 297 +/- 273 vs. 474 +/- 359, p = 0.001). Improvement of PWD and MWD could be maintained at follow up (197 +/- 254, p = 0.014; 390 +/- 324, p = 0.035, respectively) with non-smokers showing significantly better sustained PWD and MWD improvement as compared to baseline. Overall, walking capacity correlated with functional status of quality of life. Conclusions: Major findings of this investigation were that improvement in walking capacity is sustained after completion of supervised exercise training program with best results in patients who quitted or never smoked. Improved walking capacity is associated with increased functional status of quality of life.

Male and female sexual function after surgical repair of female organ prolapse

INTRODUCTION: Few data are available referring to male and female sexual function after prolapse repair of symptomatic pelvic organ. AIM: Primary aim of this study is to determine the male and female sexual function before and after surgery for pelvic organ prolapse. MAIN OUTCOME MEASURES: We used the Female Sexual Function Index (FSFI) questionnaire for female patients and for their male partners the Brief Male Sexual Inventory (BMSI) as measurement of sexual function. METHODS: We included sexually active heterosexual couples that were referred to the Department of Urogynaecology because of symptomatic cystocele, rectocele or vault descent. For cystoceles, anterior repair was performed, for rectoceles posterior repair, and for vault descent sacrospinous ligament fixation. FSFI and BMSI questionnaires were distributed before and after pelvic organ surgery and 4 months after. Female clinical examination assessing the degree of prolapse was performed before and 6 weeks after surgery. RESULTS: A full data set of 70 female questionnaires and 64 male questionnaires could be evaluated. Two cases of female de novo dyspareunia occurred. In women, FSFI scores improved significantly in the domains desire, arousal, lubrication, overall satisfaction, and particularly pain. Orgasm remained unchanged. In men, interest, sexual drive, and overall satisfaction improved significantly. Erection, ejaculatory function, and orgasm remained unchanged. Despite remaining unchanged, erection, strength of erection, ejaculation, and orgasm were not considered problems anymore compared to preoperative BMSI scores. CONCLUSION: Surgery for pelvic organ prolapse improves male and female sexual function in some domains but not in all.

AN EPIDEMIOLOGIC CASE-CONTROL ANALYSIS OF CHILDHOOD INTRACRANIAL AND SPINAL CORD TUMORS IN RELATION TO PATERNAL OCCUPATION AT BIRTH (BRAIN, CANCER)

Epidemiologic case-control studies of small groups of childhood nervous system tumor patients have suggested that parental employment in occupations with exposure to hydrocarbons is a risk factor for disease. The main focus of this case-control study was to assess the paternal occupation at the time of birth of offspring who later developed childhood intracranial and spinal tumors. All children under 15 years of age dying of such tumors in Texas, during the period 1964-1980, were selected as cases. Disease and demographic data were abstracted from death certificates. The birth certificate for each child of the final group of 499 cases was located and parental occupation information, as well as demographic and obstetric data, were collected. The comparison group consisted of a random sample from all Texas live births with the same birth year, race and sex distribution as the cases.^ The paternal occupations were categorized into broad classifications of those involving hydrocarbon exposure versus those that did not, based on the occupation criteria used in the previous studies. Odds ratios did not indicate any increased risk associated with general paternal hydrocarbon exposure in the workplace. In prior studies, increased risk estimates were detected with narrower groups of occupations involving exposure to hydrocarbon materials. The data from this study were classified according to these groups, and again, no increased risks were indicated except for a statistically insignificant but elevated odds ratio for fathers who were paper and pulp mill workers.^ Odds ratios were calculated for specific occupations and industries previously implicated as risk factors. Significantly associated odds ratios (OR) were detected for electricians (OR = 3.5), especially those working for construction companies (OR = 10.0), for employment in the printing occupations (OR = 4.5), particularly graphic arts workers (OR = 21.9), and in the electronics and electronic machinery industries (OR = 3.5). Analysis of the petroleum refining and chemical industries, which were not found in previous study populations, revealed significantly elevated odds ratios of 3.0 for occupations with probable heavy exposure to chemicals and petroleum compounds and 10.0 for salesmen of chemical products. ^

Higher emotional distress in female partners of cancer patients: prevalence and patient-partner interdependencies in a 3-year cohort

OBJECTIVE: Assessment and treatment of psychological distress in cancer patients was recognized as a major challenge. The role of spouses, caregivers, and significant others became of salient importance not only because of their supportive functions but also in respect to their own burden. The purpose of this study was to assess the amount of distress in a mixed sample of cancer patients and their partners and to explore the dyadic interdependence. METHODS: An initial sample of 154 dyads was recruited, and distress questionnaires (Hospital Anxiety and Depression Scale, Symptom Checklist 9-Item Short Version and 12-Item Short Form Health Survey) were assessed over four time points. Linear mixed models and actor-partner interdependence models were applied. RESULTS: A significant proportion of patients and their partners (up to 40%) reported high levels of anxiety, depression, psychological distress, and low quality of life over the course of the investigation. Mixed model analyses revealed that higher risks for clinical relevant anxiety and depression in couples exist for female patients and especially for female partners. Although psychological strain decreased over time, the risk for elevated distress in female partners remained. Modeling patient-partner interdependence over time stratified by patients' gender revealed specific effects: a moderate correlation between distress in patients and partners, and a transmission of distress from male patients to their female partners. CONCLUSIONS: Our findings provide empirical support for gender-specific transmission of distress in dyads coping with cancer. This should be considered as an important starting point for planning systemic psycho-oncological interventions and conceptualizing further research.

Schulische Lernfreude in der Sekundarstufe 1 und deren Beziehung zu Kontroll- und Valenzkognitionen

Im Rahmen einer Längsschnittstudie wurde untersucht, wie sich die schulische Lernfreude bei österreichischen Hauptschülern und Hauptschülerinnen zwischen der 6. und 7. Schulstufe (N = 356) entwickelt. Des Weiteren wurde die Rolle von Kontroll- und Valenzkognitionen, die gemäß der Kontroll-Wert-Theorie (Pekrun, 2000, 2006) für das Entstehen der schulischen Lernfreude zentral sein sollten, geprüft. Als Methoden zur Erfassung der habituellen und aktuellen Merkmale kamen Fragebögen und Tagebücher zum Einsatz. Die Ergebnisse belegen den Rückgang der Lernfreude während dieses von Fend (1997) als «kritisch» bezeichneten Schuljahres. Ebenso erweisen sich hohe Kontrollkognitionen und positive Valenzkognitionen als bedeutsam für die schulische Lernfreude, sie schützen jedoch nicht vor ihrem Rückgang. Der Zusammenhang von Lernfreude und Kognitionen bedarf daher weiterer Klärung.

Relaxing hydrotherapy WATSU (WaterShiatsu) and its effects in third trimester of pregnancy

Background WATSU (WaterShiatsu) is a bodywork-technique comprising buoyancy, passive stretches, massage, and acupressure that is administered in 35° C warm water. WATSU is believed to exert beneficial effects on pregnancy-related complaints. We conducted a pilot study to test the hypothesis that WATSU treatment during pregnancy can affect low back pain, everyday stress perception, quality of life, tonus of the uterus, amount of amniotic fluid, spontaneous course of breech presentations, and the success rate of external cephalic versions. Methods Healthy women with singleton pregnancies at gestational week 36 were included in our cohort control pilot trial. Participants in the treatment group (n = 8) received a standardized WATSU-treatment on their first and fourth day of study participation, while participants in the control group were in a waiting condition. Participants underwent ultrasound investigations and completed quantitative and qualitative questionnaires before and after intervention, as well as weekly until birth. Results In contrast to the control group, participants in the WATSU-treatment group reported significant relief of low back pain and stress. After WATSU treatment spontaneous version out of breech position occurred once in seven cases, and external cephalic version was successful in two out of three cases. As qualitative data indicate, WATSU was appreciated as a deep relaxing and enjoyable treatment method. No negative side-effects or adverse events were reported. Conclusion The findings from our pilot-study support the notion that WATSU might yield therapeutic benefits for pregnant women and warrant further research.

Workshop: ASSIP - Attempted Suicide Short Intervention Program. Theory, Practice, and 24 Months Follow-up RCT.

Background: ASSIP is a manualized brief therapy based on a model of suicide as goal-directed action, aimed at establishing a therapeutic alliance in a patient-oriented, collaborative approach. The main goals of the three-session program ASSIP are for patients to understand, from an observer’s position, patterns leading to a suicidal crisis, recognize triggers and warning signs, and to establish individual safety strategies for future suicidal crises. An ongoing therapeutic support is provided with regular letters over 24 months. Method: The study was conducted in a naturalistic setting. 120 Patients were randomly assigned to an intervention group (60 participants) treated with ASSIP combined with follow-up contact through letters, and a control group (60 participants) receiving a single session of clinical assessment. Both groups had treatment as usual. Patients completed a set of psychosocial and clinical questionnaires every six months over a period of 24 months. Results: In the ASSIP group 5 patients made a total of 5 reattempts, compared to 15 patients with 41 reattempts in the control group. The survival analysis yielded a significant difference with a Wald Chi2 of .000003. The ASSIP group had significantly lower suicidal ideation and fewer days of inpatient treatment compared to the control group. Higher scores in the Penn Helping Alliance Questionnaire were associated with lower suicidal ideation during follow-up. Conclusions: ASSIP is a highly effective brief therapy for patients with recent suicide attempts. Forming a strong therapeutic alliance is considered to be a major factor for outcome. ASSIP can be used with minimal training by experienced therapists. An English version of the manual will be published in May 2015.

Medical, psychological and socio-economic implications of chronic hand eczema: a cross-sectional study.

BACKGROUND Hand eczema (HE) is a common skin disease with major medical psychological and socio-economic implications. Onset and prognosis of HE are determined by individual as well as environmental factors. So far, most epidemiological data on HE have been reported from Scandinavian and recently German studies. OBJECTIVE To investigate the characteristics and medical care of patients with chronic HE (CHE) in Switzerland, and identify risk factors. METHODS In this cross-sectional study, data from patients with chronic HE were obtained by means of medical history, dermatological examination and patient questionnaires. Multiple logistic regression analysis was applied to identify risk factors for high severity and dermatology life quality index (DLQI). RESULTS In seven dermatology departments, 199 patients (mean age 40.4 years, 50.8% female) with CHE (mean duration 6.6 years) were enrolled. Moderate to severe HE was reported by 70.9% of patients, and was associated with age <30 or >50 years, localization of lesions and pruritus. Because of the CHE, 37.3% of patients were on sick leave over the past 12 months, 14.8% had changed or lost their job. Practically all patients applied topical therapy, 21% were treated with alitretinoin, and 21% with psoralen plus UVA light (PUVA). The effects on the health-related quality of life was moderate to large in 33.7% and 39.4% of CHE patients, respectively. Factors associated with a high impact on DLQI (mean 9.7 ± 5.8) were female sex, lesions on back of the hands and pruritus as well as mechanical skin irritation and wearing gloves. CONCLUSION In agreement with recent studies, the Swiss data demonstrate the high impact of CHE on medical well-being, patient quality of life and work ability. As it is associated with an intense use of health care services, high rate of sick leave, job loss and change, CHE may cause a high socio-economic burden.

Picea abies in Europe: distribution, habitat, usage and threats

Among the coniferous species, Norway spruce (Picea abies (L.) Karst.) is one of the most important trees in Europe both for economic and ecological aspects, with a long tradition of cultivation. It can be a big tree, reaching 50-60 m in height with a straight and regular trunk, particularly used for timber constructions, pulpwood for paper and furniture. This widespread species dominates the Boreal forests in Northern Europe and the subalpine areas of the Alps and Carpathian Mountains. Thanks to its high performances in different site conditions, it can also be found outside its natural distribution on lower elevations in more temperate forests. Norway spruce has been massively planted up to its niche limits, where it is particularly susceptible to heat and drought, due to its shallow root system. For this reason it is expected to be severely affected under global warming conditions. Disturbed and weakened plants can be easily attacked by rot fungi such as Heterobasidion annosum and Armillaria, or by the bark beetles Ips typographus, one of the most destructive spruce forest pests.

Barriers to cross-border research projects: A prelude to improving professional collaborations between the United States and Mexico

Study objective. This was a secondary data analysis of a study designed and executed in two phases in order to investigate several questions: Why aren't more investigators conducting successful cross-border research on human health issues? What are the barriers to conducting this research? What interventions might facilitate cross-border research? ^ Methods. Key informant interviews and focus groups were used in Phase One, and structured questionnaires in Phase Two. A multi-question survey was created based on the findings of focus groups and distributed to a wider circle of researchers and academics for completion. The data was entered and analyzed using SPSS software. ^ Setting. El Paso, TX located on the U.S-Mexico Border. ^ Participants. Individuals from local academic institutions and the State Department of Health. ^ Results. From the transcribed data of the focus groups, eight major themes emerged: Political Barriers, Language/Cultural Barriers, Differing Goals, Geographic Issues, Legal Barriers, Technology/Material Issues, Financial Barriers, and Trust Issues. Using these themes, the questionnaire was created. ^ The response rate for the questionnaires was 47%. The largest obstacles revealed by this study were identifying a funding source for the project (47% agreeing or strongly agreeing), difficulties paying a foreign counterpart (33% agreeing or strongly agreeing) and administrative changes in Mexico (31% agreeing or strongly agreeing). ^ Conclusions. Many U.S. investigators interested in cross-border research have been discouraged in their efforts by varying barriers. The majority of respondents in the survey felt financial issues and changes in Mexican governments were the most significant obstacles. While some of these barriers can be overcome simply by collaboration among motivated groups, other barriers may be more difficult to remove. Although more evaluation of this research question is warranted, the information obtained through this study is sufficient to support creation of a Cross-Border Research Resource Manual to be used by individuals interested in conducting research with Mexico. ^

Development and evaluation of a nutrition education program designed to increase fruit and vegetable consumption in girls, ages 9--12

The purpose of this study is to evaluate the theory-based Eat 5 nutrition badge. It is designed to increase fruit and vegetable (F&V) intake in 4th-6th grade junior Girl Scouts. Twenty-two troops were recruited and randomized by grade level (4th, 5th, 6th, or mixed) into either the intervention or control conditions. The leaders in the intervention condition received a brief training and the materials and conducted the program with their troops during four meetings. The Girl Scouts in the intervention condition completed 1-day Food Frequency Questionnaires and Nutrition Questionnaires both before and after completing the Eat 5 badge, and a third measurement of F&V intake three months after the posttest. Girl Scouts in the control condition were only evaluated at the three time periods.^ The primary hypotheses were that the Girl Scouts in the intervention condition would increase their daily intake of fruits and vegetables at both the posttest and three months later, compared to the Girl Scouts in the control condition. Other study questions investigated the impact of the Eat 5 program on intervening variables such as knowledge, self-efficacy, barriers, norms, F&V preference, and F&V selection and preparation skills.^ A nested ANOVA, with troop as the unit of analysis nested within condition, was used to assess the effects of the program. Pretest F&V intake and grade level were used as covariates. Pretest mean F&V intake for the total sample of 210 girls was 2.50 servings per day; 3.0 for the intervention group (n = 101). Significant increases in F&V intake (to 3.4 servings per day), knowledge, and fruit and vegetable preference were found for the intervention condition troops compared to the troops in the control condition. Three months later, the mean F&V intake had returned to pretest levels.^ This study indicates that social groups such as Girl Scouts can provide a channel for nutrition education. Long term effects were not sustained by the intervention; a possible cause was the lack of change in self-efficacy. Therefore, additional interventions are recommended such as booster lessons to maintain increased F&V intake by Girl Scouts. ^

Epidemiology of perinatal mortality: Birthweight, crown -heel length, gestational age, and weight -for -height

Studies suggest that slim infants (low weight-for-height) experienced higher mortality rates than average or high weight-for-height infants (Miller and Hassanein, 1973; Hoffman, Meirik, and Bakketeig, 1984). In this study, the 1980 National Natality Survey and the National Fetal Mortality Survey were used to examine the association of weight, height and perinatal mortality. All singleton births to white married mothers, between 18 and 34 years of age and of parity less than 4, for whom both mother's and hospital questionnaires were completed in those two surveys (3796 live births and 2043 fetal deaths) were selected for analysis. Overall, low weight and height infants had excess mortality rates. However, after adjustment for low birthweight and preterm birth status, low weight and height infants had only slightly higher mortality rates than their medium or high weight and height counterparts. The current study consists of relatively well-educated white married mothers of optimal reproductive age and low parity. Therefore, lower than expected mortality rates for slim infants may be attributed to these favorable demographic factors in this sample as compared with previous studies, or because of advances in perinatal medicine, slim infants may be prevented from achieving the high mortality seen in earlier studies. ^

New Constructive Solutions to Improve Energy Efficiency in Existing Buildings and their Economic Viability

The improvement of energy efficiency in existing buildings is always a challenge due to their particular, and sometimes protected, constructive solutions. New constructive regulations in Spain leave a big undefined gap when a restoration is considered because they were developed for new buildings. However, rehabilitation is considered as an opportunity for many properties because it allows owners to obtain benefits from the use of the buildings. The current financial and housing crisis has turned society point of view to existing buildings and making them more efficient is one of the Spanish government’s aims. The economic viability of a rehabilitation action should take all factors into account: both construction costs and the future operative costs of the building must be considered. Nevertheless, the application of these regulations in Spain is left to the designer’s opinion and always under a subjective point of view. With the research work described in this paper and with the help of some case-studies, the cost of adapting an existing building to the new constructive regulations will be studied and Energetic Efficiency will be evaluated depending on how the investment is recovered. The interest of the research is based on showing how new constructive solutions can achieve higher levels of efficiency in terms of energy, construction and economy and it will demonstrate that Life Cycle Costing analysis can be a mechanism to find the advantages and disadvantages of using these new constructive solutions. Therefore, this paper has the following objectives: analysing constructive solutions in existing buildings - to establish a process for assessing total life cycle costs (LCC) during the planning stages with consideration of future operating costs - to select the most advantageous operating system – To determine the return on investment in terms of construction costs based on new techniques, the achieved energy savings and investment payback periods.

PROFILE AND THE QUALITY OF LIFE OF LOGGERS

RESUMO – Objetivou-se com este estudo caracterizar o perfil e avaliar o nível de satisfação que reflete na qualidade de vida no trabalho (QVT) de trabalhadores da colheita de madeira de duas contratadas (C1 e C2), por duas grandes empresas do setor florestal, sendo uma do segmento de papel e celulose (PC) e, a outra, do segmento de carvão vegetal (CV). A avaliação ocorreu a partir da percepção dos trabalhadores das contratadas em questão, utilizando um modelo pré-concebido que contempla 11 blocos ou dimensões referentes a variáveis intervenientes e definidores da QVT, englobando 48 trabalhadores em três categorias funcionais: operador de motosserra (7 trabalhadores da C1 PC e 10 da C2 CV), ajudante de motosserrista (7 trabalhadores da C1 PC e 8 da C2 CV) e operador de carregador florestal (11 trabalhadores da C1 PC e 5 da C2 CV). Os dados referentes às variáveis intervenientes na QVT foram obtidos a partir de escala fechada do tipo Likert, com os escores variando de 1 a 7, em que 1 correspondeu ao nível "bastante insatisfeito" e 7, ao nível "bastante satisfeito". O perfil dos trabalhadores é de pessoa jovem, baixo nível de escolaridade e pouco tempo de serviço na empresa. Quanto ao nível de satisfação no trabalho, constatou-se que os trabalhadores da C1 PC se encontravam "satisfeitos" e os da C2 CV, "mediamente satisfeitos" com o trabalho e as condições proporcionadas pelas respectivas empresas, apesar de estatisticamente não ter sido detectada diferença entre os valores médios encontrados nas duas situações, pelo teste de Mediana (P>0,01). Os fatores que mais contribuíram para esses resultados favoráveis foram os benefícios extras oferecidos pelas prestadoras de serviços, as condições de segurança no trabalho e o contentamento com o emprego formal. ABSTRACT – The objective of this study was to characterize profile and satisfaction level, which reflects the quality of life (QOL) of forest workers of two contracts for harvest activities, one in the pulp and paper industry (PI) and another in charcoal industry (CI). The evaluation of the satisfaction indexes was carried out according to the workers perception by using a model including 11 parameters to reflect these workers QOL. The group study of 48 workers encompassed three functional categories: chainsaw operators (7 from C1 and 10 from C2), chainsaw operator's assistant (7 from C1 and 8 from C2), and log loader operators (11 from C1 and 5 from C2). Data regarding the factors involved in QOL were collected from a closed, Likert-type scale with scores ranging from 1-7, in which level 1 corresponded to "very dissatisfied" and level 7 to "very satisfied". The general profile of the group shows that most of them are young, with low level of education and employed in the companies for a short time. Overall, the employees of contractors of the paper and pulp industry are "satisfied" and those working for the charcoal company are only "moderately satisfied" with the work and policies offered by the respective companies, although no significant statistical difference was detected between the two groups, for the median test (P> 0.01). The main reasons behind these results are the general beneficts offered by the companies, the safety measurements and the overall satisfaction for been employed.
