Survey of aspergillosis in non-neutropenic patients in Swiss teaching hospitals.

Clin Microbiol Infect 2011; 17: 1366-1371 ABSTRACT: Invasive aspergillosis (IA) is a live-threatening opportunistic infection that is best described in haematological patients with prolonged neutropenia or graft-versus-host disease. Data on IA in non-neutropenic patients are limited. The aim of this study was to establish the incidence, disease manifestations and outcome of IA in non-neutropenic patients diagnosed in five Swiss university hospitals during a 2-year period. Case identification was based on a comprehensive screening of hospital records. All cases of proven and probable IA were retrospectively analysed. Sixty-seven patients were analysed (median age 60 years; 76% male). Sixty-three per cent of cases were invasive pulmonary aspergillosis (IPA), and 17% of these were disseminated aspergillosis. The incidence of IPA was 1.2/10 000 admissions. Six of ten cases of extrapulmonary IA affected the brain. There were six cases of invasive rhinosinusitis, six cases of chronic pulmonary aspergillosis, and cases three of subacute pulmonary aspergillosis. The most frequent underlying condition of IA was corticosteroid treatment (57%), followed by chronic lung disease (48%), and intensive-care unit stays (43%). In 38% of patients with IPA, the diagnosis was established at autopsy. Old age was the only risk factor for post-mortem diagnosis, whereas previous solid organ transplantation and chronic lung disease were associated with lower odds of post-mortem diagnosis. The mortality rate was 57%.

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.

Impact of antiretroviral therapy (ART), immunosuppression and viraemia on lipid levels: the D:A:D study

Purpose of the study: To investigate the impact of ART, HIV viremia and immunosuppression on triglyceride (TG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) levels. Methods: We considered the cross-sectional associations between TG, TC and HDL-C (mmol/l; first available measurement on/after enrolment in the D:A:D study) and use of ART, HIV viral load (VL; copies/ml), and CD4 count (cells/mm3) measured at the same time. TG was log10 transformed to ensure normality. Analyses were performed using linear regression and adjusted for other factors known to impact lipid levels (table footnote). ART and VL status were combined (off ART&VL _100,000, off ART&VL B100,000, on ART&VL B500, on ART&VL _500), current and nadir CD4 count were categorised as B200, 200_349, 350_499 and _500. Summary of results: 44,322/49,734 participants in the D:A:D Study (89.1%) contributed a TG measurement (median; IQR 1.52; 1.00_ 2.45), 45,169 (90.8%) a TC measurement (4.80; 4.00_5.70) and 38,604 (77.6%) a HDL-C measurement (1.12; 0.90_1.40). Most participants were male (74%), of white ethnicity (51%), without AIDS (78%), were not receiving lipid-lowering drugs (4%) and were ART experienced (61%) with 47% previously exposed to PIs, 61% previously exposed to NRTIs and 29% previously exposed to NNRTIs. The median (IQR) age, current CD4 count and CD4 nadir were 38 (36_45) years, 400 (242_590) cells/ml and 240 (100_410) cells/ml respectively. Compared to those on ART with a suppressed VL, all lipids were lower for those off ART (Table); non-suppressive ART was also associated with lower TC and HDL-C levels (no impact on TG). A low current CD4 count was associated with lower lipid levels, whereas a low nadir CD4 count was associated with higher TC and TG levels. Prior AIDS diagnosis was associated with higher TG and TC, but lower HDL-C levels. Conclusion: Although specific drug classes were not considered, lipid levels are considerably higher in those on a suppressive ART regimen. The higher TC/TG and lower HDL-C levels seen among those with low nadir CD4 count and with a prior AIDS diagnosis suggests severe immunosuppression may be associated with dyslipidaemia over the long-term.

Teaching cardiac auscultation to trainees in internal medicine and family practice: does it work?

BACKGROUND: The general proficiency in physical diagnostic skills seems to be declining in relation to the development of new technologies. The few studies that have examined this question have invariably used recordings of cardiac events obtained from patients. However, this type of evaluation may not correlate particularly well with bedside skills. Our objectives were 1) To compare the cardiac auscultatory skills of physicians in training with those of experienced cardiologists by using real patients to test bedside diagnostic skills. 2) To evaluate the impact of a five-month bedside cardiac auscultation training program. METHODS: 1) In an academic primary care center, 20 physicians (trainees in internal medicine and family practice) and two skilled academic cardiologists listened to 33 cardiac events in 13 patients directly at bedside and identified the cardiac events by completing an open questionnaire. Heart sounds, murmurs and diagnosis were determined beforehand by an independent skilled cardiologist and were validated by echocardiography. Thirteen primary cardiologic diagnoses were possible.2) Ten of the physicians agreed to participate in a course of 45-minute sessions once a week for 5 months. After the course they listened again to the same patients (pre/post-interventional study). RESULTS: 1) The experts were the most skillful, achieving 69% recognition of heart sounds and murmurs and correct diagnoses in 62% of cases. They also heard all of the diastolic murmurs. The residents heard only 40% of the extra heart sounds and made a correct diagnosis in 24% of cases. 2) After the weekly training sessions, their mean percentage for correct diagnosis was 35% [an increase of 66% (p < 0.05)]. CONCLUSIONS: The level of bedside diagnostic skills in this relatively small group of physicians in training is indeed low, but can be improved by a course focusing on realistic bedside teaching.

Art et Observance à Venise : les Dominicains et leurs artistes (1391-1545)

L'Observance est le premier mouvement de réforme avant la Contre-réforme promu par l'Eglise elle-même, dès la fin du XlVème siècle. Visant à restaurer une plus grande observance de la Règle au sein des Ordres religieux, par l'importance accordée à la vie commune, à la formation intellectuelle de ses membres et à l'oraison mentale, elle joue un rôle de premier plan dans la vie des cités au XVème siècle. Tantôt instrument du pouvoir civil tantôt de la papauté, elle est un acteur fondamental dans le panorama urbain, aspirant à contrôler la vie religieuse des laïcs, grâce à ses prédicateurs et son intense activité pastorale, fondée sur l'édition de traités dévotionnels et de manuels pour la prière. L'objet de cette thèse est l'étude des relations entre ce mouvement de réforme religieuse et la production artistique, afin de comprendre la contribution de l'Observance aux transformations importantes que l'image de culte tant publique que privée connaît entre le XVème et le XVIème siècle. Elle montre que l'Observance et les formes de dévotion qu'elle promeut participent non seulement des choix iconographiques mais également formels, et pose la question de l'existence et de la définition d'une esthétique observante. L'analyse se concentre sur la ville de Venise et les Dominicains à partir de 1391, date de l'introduction de l'Observance dans la cité, jusqu'en 1545, qui marque le début du Concile de Trente. La perspective diachronique adoptée a permis de révéler une véritable politique artistique de l'Observance dominicaine, qui fait un usage réfléchi et conscient des images. Celles-ci permettent, d'une part de décliner l'identité de l'Ordre de diverses manières en fonction de la situation religieuse et historique et des destinataires, d'autre part de contrôler et informer la dévotion du fidèle. La perspective diachronique éclaire également comment l'Observance dominicaine a fait face à des mouvements religieux importants, qui promeuvent des pratiques dévotionnelles christocentriques, fondées sur un rapport direct et individuel avec le divin. Il s'agit au XVème siècle de la Devotio moderna, puis au XVIème siècle de la Réforme protestante, mais aussi des divers mouvements de spiritualité évangélique dont Venise est un centre de diffusion. Pour un Ordre voué à la défense de la papauté et de l'Eglise, ces formes de dévotion individuelles constituaient des menaces auxquelles il fallait opposer des formes de dévotion individuelles contrôlées. A cette fin, l'utilisation des images s'est révélée un instrument puissant. Après une première partie historique qui offre une reconstruction de certaines églises dominicaines détruites et établit un corpus d'oeuvres, les rapports de l'Observance et des oeuvres d'art sont analysés selon trois angles d'approche. Le premier se concentre sur la question des femmes, et aborde le problème de l'utilisation des images dans la direction spirituelle des nonnes ainsi que dans la construction d'une identité féminine dominicaine. Le deuxième prend en considération l'utilisation des images dans la dévotion privée des frères eux-mêmes. Le troisième et dernier angle d'approche concerne l'utilisation des images pour définir l'identité de l'Ordre face aux représentants des autorités politiques et religieuses, mais aussi des fidèles.
