Burnout and associated factors in employees of a Swiss teaching hospital

Background Working in a teaching hospital is a highly stressful occupation, which can lead to burnout. The consequences of burnout in health professionals can be very serious, both for themselves and patients. The aim of this cross-sectional study was to assess the extent of burnout and associated factors in hospital employees. Methods In the Fall of 2007, all employees of a Swiss teaching hospital were invited to complete a job satisfaction survey. It included the work-related burnout scale (scored 0-100) of the Copenhagen Burnout Inventory (CBI-French version), measuring the degree of physical and psychological fatigue and exhaustion perceived as related to the person's work; a high degree of burnout was defined as a score _50. Logistic regression analyses were used to determine factors associated with a high degree of burnout. Results A total of 4575 individuals returned the questionnaire (response rate 54%). Of them, 1503 (33%) had a high degree of burnout. The rate of burnout was higher among women (34.3% versus 30.5%, P = 0.012) and respondents younger than 40 years (37.7% versus 28.6%, P < 0.001). Executives were less prone to burnout than employees (27.1% versus 33.9%, P < 0.0019). Rates of burnout differed by profession: nurses and physicians had higher rates than administrative and logistic staff (42.8% and 37.4% versus 25.6% and 20.9%, respectively P < 0.001). Burnout was inversely associated with job satisfaction. In multivariate analysis, factors associated with burnout were overall dissatisfaction (OR 3.23; 95% CI 2.66-3.91), dissatisfaction with workload (OR 2.09; 95% CI 1.74-2.51) and work-life balance (OR 2.25; 95% CI 1.83-2.77), being a woman (OR 1.56; 95% CI 1.28-1.90), working fulltime (OR 1.41; 95% CI 1.08-1.85) and working as a nurse, a physician or in the psychosocial sector. Conclusions One-third of respondents, mostly nurses and physicians, experienced burnout and had lower levels of job satisfaction. The factors associated with burnout may help to tailor programmes aiming at reducing burnout at both the individual and organizational level within the hospital.

Predicted effects of small decreases in energy expenditure on weight gain in adult women.

Small daily positive energy imbalances of 200 to 800 kJ (about 50 to 200 kcal) due to reduced resting energy expenditure (REE), reduced diet-induced thermogenesis, or physical inactivity are believed to predispose to obesity. However, estimates of the magnitude of the weight gain often fail to account for concurrent changes in body composition and increases in maintenance energy requirements as weight increases and energy equilibrium is re-established. Using previously reported data on body composition and REE in women and the energy cost of tissue deposition, we used mathematical models to predict the theoretical effect of a persistent reduction in energy expenditure on long-term weight gain, assuming no adaptation in energy intake. The analyses indicate the following effects of a reduced level of energy expenditure in lean and obese women: (i) REE rises more slowly with increasing degrees of obesity due to a declining proportion of the more metabolically active fat-free mass; so, for the same positive energy balance, a significantly greater weight gain is expected for obese than for lean women before energy equilibrium is re-established; (ii) due to the greater energy density of adipose tissue, the time course of weight gain to achieve energy balance is longer for obese subjects: in general, this is approximately five years for lean and ten years for obese women; (iii) the magnitude of weight gain of lean women in response to a reduced energy expenditure of 200 to 800 kJ/day is only about 3 to 15 kg, amounts insufficient to explain severe obesity.

Antiepileptika bei Frauen im gebärfähigen Alter und in der Schwangerschaft : Vergleich der Fachinformationen in Deutschland und der Schweiz mit dem aktuellen Wissensstand [Antiepileptics in women of childbearing age and during pregnancy : Comparison of specialized information with the current state of knowledge in Germany and Switzerland].

BACKGROUND: Healthcare professionals regularly read the summary of product characteristics (SmPC) as one of the various sources of information on the risks of drug use in women of childbearing age and during pregnancy. The aim of this article is to present an overview of the teratogenic potential of various antiepileptic drugs and to compare these data with the information provided by the SmPCs. METHODS: A literature search on the teratogenic risks of 19 antiepileptic agents was conducted and the results were compared with the information on the use in women of childbearing age and during pregnancy provided by the SmPCs of 38 commercial products available in Switzerland and Germany. RESULTS: The teratogenic risk is discussed in all available SmPCs. Quantification of the risk for birth defects and the numbers of documented pregnancies are mostly missing. Reproductive safety information in SmPCs showed poor concordance with risk levels reported in the literature. Recommendations concerning the need to monitor plasma levels and possibly perform dose adjustments during pregnancy to prevent treatment failure were missing in five Swiss and two German SmPCs. DISCUSSION: The information regarding use in women of childbearing age and during pregnancy provided by the SmPCs is heterogeneous and poorly reflects the current state of knowledge. Regular updates of SmPCs are warranted in order for these documents to be of reliable use for health care professionals.

A prospective randomised double-blind controlled trial evaluating the effect of trans-sacral magnetic stimulation in women with overactive bladder.

Overactive bladder (OAB) is a prevalent condition with 16% of adults having one or more symptoms that significantly affect quality of life. Transcutaneous electrical nerve stimulation and neuromodulators have had success in treating OAB but are expensive, invasive, and sometimes cumbersome. We developed an alternative neuromodulatory technique that involves electromagnetic stimulation of the sacral nerve roots with a portable electromagnetic device to produce trans-sacral stimulation of the S3 and S4 sacral nerve roots. The aim of this study was to evaluate the impact of this device on OAB symptoms in women with a prospectively randomised double-blind controlled study. Following a power analysis, women with symptoms of OAB were prospectively recruited with ethical approval for randomisation to an active treatment (n = 33) or placebo group (n = 30) in a double-blind trial. The patient, at home, used the belt device daily for 20 min over 12 weeks. Outcome measures included a 3-day voiding diary, 1 h pad test, visual analogue score (VAS) for symptom impact (0-100%), Kings Health Questionnaire (KHQ) and Australian Quality of Life questionnaire (AQOL) at baseline, 6 and 12 weeks. Overall, no difference was found between groups for any of the research questions. Specifically, we were unable to demonstrate any difference between the active and sham device groups in frequency, nocturia, urinary leakage, or quality of life, nor was there any evidence of a placebo effect. The quality of the data was high with the number of missing observations (especially for disease specific KHQ and general AQOL) being few. This attempt to promote trans-sacral electromagnetic neuromodulation with a specially created device was ineffective on the symptoms of OAB.

Trabecular bone score is associated with volumetric bone density and microarchitecture as assessed by central QCT and HRpQCT in Chinese American and white women.

Although high-resolution peripheral quantitative computed tomography (HRpQCT) and central quantitative computed tomography (QCT) studies have shown bone structural differences between Chinese American (CH) and white (WH) women, these techniques are not readily available in the clinical setting. The trabecular bone score (TBS) estimates trabecular microarchitecture from dual-energy X-ray absorptiometry spine images. We assessed TBS in CH and WH women and investigated whether TBS is associated with QCT and HRpQCT indices. Areal bone mineral density (aBMD) by dual-energy X-ray absorptiometry, lumbar spine (LS) TBS, QCT of the LS and hip, and HRpQCT of the radius and tibia were performed in 71 pre- (37 WH and 34 CH) and 44 postmenopausal (21 WH and 23 CH) women. TBS did not differ by race in either pre- or postmenopausal women. In the entire cohort, TBS positively correlated with LS trabecular volumetric bone mineral density (vBMD) (r = 0.664), femoral neck integral (r = 0.651), trabecular (r = 0.641) and cortical vBMD (r = 0.346), and cortical thickness (C/I; r = 0.540) by QCT (p < 0.001 for all). TBS also correlated with integral (r = 0.643), trabecular (r = 0.574) and cortical vBMD (r = 0.491), and C/I (r = 0.541) at the total hip (p < 0.001 for all). The combination of TBS and LS aBMD predicted more of the variance in QCT measures than aBMD alone. TBS was associated with all HRpQCT indices (r = 0.20-0.52) except radial cortical thickness and tibial trabecular thickness. Significant associations between TBS and measures of HRpQCT and QCT in WH and CH pre- and postmenopausal women demonstrated here suggest that TBS may be a useful adjunct to aBMD for assessing bone quality.

Breast cancer incidence in younger swiss women

Background Breast cancer in younger women has received increased attention in recent years. Although breast cancer is uncommon in young women, it is the most frequent cancer and the leading cause of cancer death for younger women in developed countries. For Switzerland, the United States and several European countries, declines in breast cancer incidence have been reported since around the year 2000, after decades of increase, among women aged 50 and older. On the other hand an increase in the incidence of breast cancer in younger women has been reported in recent years. Therefore, this study aims to evaluate time trends in breast cancer incidence in younger women in Switzerland. Methods Data on invasive breast cancer cases were obtained from the Swiss Cancer Registries of Basel, Fribourg, Geneva, Graubunden/Glarus, Jura, Neuchatel, St. Gallen-Appenzell, Ticino, Valais, Vaud and Zurich, covering the time period 1996 to 2009. Mid-year population estimates for the respective time period were supplied by the Swiss Federal Statistical Office. For females aged 20-49 years, annual age-standardized incidence rates (ASIRs) (European standard) per 100,000 person-years and corresponding 95%-confidence intervals (95% CI) were calculated. For females aged 20-39 and 40-49 years, ASIRs and incidence rate ratios (IRRs) were calculated by grouped time periods, consisting of 3-5 incidence years. IRRs and corresponding 95% CI were calculated using Poisson regression adjusting for age (reference period 1996-2000). Results ASIRs in females aged 20-49 increased gradually since 1996, being 57.36 per 100,000 person-years in 1996 (95% CI 52.54-62.51) and rising to 68.34 (95% CI 63.40-73.57) per 100,000 person-years in 2009. Comparing the time-period 2007-2009 and the reference period 1996-2000, IRRs show values of 1.17 (95% CI 1.04-1.31) for the age-group 20-39 years and 1.04 (95% CI 0.97-1.10) for the age-group 40-49 years. Conclusions Our findings confirm a slight increase in the incidence of invasive breast cancer in younger women in Switzerland during the period 1996-2009. An increase in breast cancer incidence in younger patients is an important public health problem. It warrants further investigations to identify specific risk factors of this population and to better understand the biology of this particular breast cancer.

Hommes et femmes: sommes-nous tous égaux face à la douleur [Are there differences between men and women with pain?].

An increasing number of articles are published on the differences about pain in men and women. These differences seem to be due to the sex, the biological dimension of the person, and to the gender, which is the role given to that person in a given social and culture environment. The pain prevalence is higher in women, its threshold and tolerance are lower. The pain interpretation, its perception and the coping is also different in men and women. Finally doctors translate and treat pain differently. This article proposes some explanations on these differences which should help us to treat this frequent and noxious symptom for the quality of life in a better way.

Adiponectin isoform distribution in serum and in follicular fluid of women undergoing treatment by ICSI.

Adiponectin is an adipokine, present in the circulation in comparatively high concentrations and different molecular weight isoforms. For the first time, the distribution of these isoforms in serum and follicular fluid (FF) and their usefulness as biological markers for infertility investigations was studied. In vitro study. University based hospital. Fifty-four women undergoing intracytoplasmic sperm injection (ICSI). Oocytes were retrieved, fertilized in vitro using ICSI, and the resulting embryos transferred. Serum was collected immediately prior to oocyte retrieval. Adiponectin isoforms (high molecular weight (HMW), medium and low molecular weight) were determined in serum and FF. Total adiponectin and the different isoform levels were compared with leptin and ovarian steroid concentrations. Adiponectin isoforms in serum and FF. Adiponectin isoform distribution differed between serum and FF; the HMW fraction made up half of all adiponectin in the serum but only 23.3% in the FF. Total and HMW adiponectin in both serum and FF correlated negatively with the body mass index and the concentration of leptin. No correlations were observed for total adiponectin or its isoforms with estradiol, progesterone, anti-Mullerian hormone, inhibin B, or the total follicle stimulating hormone (FSH) dose administered during the ovarian stimulation phase. This study shows for the first time that adiponectin isoform distribution varies between the serum and FF compartments in gonadotropin stimulated patients. A trend towards higher HMW adiponectin serum levels in successful ICSI cycles compared to implantation failures was observed; studies with larger patient groups are required to confirm this observation.

Effect of a novel beta-adrenoceptor agonist (Ro 40-2148) on resting energy expenditure in obese women.

The aim of this single-blind, placebo-controlled study was to investigate the effects of the new beta-adrenergic compound Ro 40-2148 on resting energy expenditure (REE) at rest and after an oral glucose load in non-diabetic obese women before and after two weeks of treatment. After one week of placebo administration and after an overnight fast and one hour rest, REE and glucose and lipid oxidation rates were measured by indirect calorimetry (hood system) before and for 6 h after a single dose of placebo solution. A 75 g oral glucose tolerance test (OGTT) was performed during this period starting 90 min after the placebo administration. During the following two weeks, using a randomization design, six patients received Ro 40-2148 at a dose of 400 mg diluted in 100 ml water twice a day (i.e. 800 mg per day), while six others continued with the placebo administration. The same tests and measurements were repeated after two weeks, except for the treatment group which received the drug instead of the placebo. The 14-day period of drug administration did not increase REE measured in post-absorptive conditions. Similarly, there was no acute effect on REE of a 400 mg dose of Ro 40-2148. In contrast, glucose-induced thermogenesis was significantly increased after two weeks in the treatment group (means +/- s.e.m.: 3.7 +/- 1.3%, P = 0.047), while no change was observed in the placebo group (-0.8 +/- 0.7%, not significant). Since there was no significant change in the respiratory quotient, the increase in energy expenditure observed in the treatment group was due to stimulation of both lipid and glucose oxidation. The drug induced no variations in heart rate, blood pressure, axillary temperature or in plasma glucose, insulin and free fatty acid levels. In conclusion, this study shows that Ro 40-2148 activates glucose-induced thermogenesis in obese non-diabetic patients.

Prevention of preterm delivery with vaginal progesterone in women with preterm labour (4P): randomised double-blind placebo-controlled trial.

OBJECTIVE: To evaluate the effectiveness of 200 mg of daily vaginal natural progesterone to prevent preterm birth in women with preterm labour. DESIGN: Multicentre, randomised, double-blind, placebo-controlled trial. SETTING: Twenty-nine centres in Switzerland and Argentina. POPULATION: A total of 385 women with preterm labour (24(0/7) to 33(6/7)  weeks of gestation) treated with acute tocolysis. METHODS: Participants were randomly allocated to either 200 mg daily of self-administered vaginal progesterone or placebo within 48 hours of starting acute tocolysis. MAIN OUTCOME MEASURES: Primary outcome was delivery before 37 weeks of gestation. Secondary outcomes were delivery before 32 and 34 weeks, adverse effects, duration of tocolysis, re-admissions for preterm labour, length of hospital stay, and neonatal morbidity and mortality. The study was ended prematurely based on results of the intermediate analysis. RESULTS: Preterm birth occurred in 42.5% of women in the progesterone group versus 35.5% in the placebo group (relative risk [RR] 1.2; 95% confidence interval [95% CI] 0.93-1.5). Delivery at <32 and <34 weeks did not differ between the two groups (12.9 versus 9.7%; [RR 1.3; 95% CI 0.7-2.5] and 19.7 versus 12.9% [RR 1.5; 95% CI 0.9-2.4], respectively). The duration of tocolysis, hospitalisation, and recurrence of preterm labour were comparable between groups. Neonatal morbidity occurred in 44 (22.8%) cases on progesterone versus 35 (18.8%) cases on placebo (RR: 1.2; 95% CI 0.82-1.8), whereas there were 4 (2%) neonatal deaths in each study group. CONCLUSION: There is no evidence that the daily administration of 200 mg vaginal progesterone decreases preterm birth or improves neonatal outcome in women with preterm labour.
