Clara cell protein and surfactant protein B in garbage collectors and in wastewater workers exposed to bioaerosols

OBJECTIVES: Inhalation of bioaerosols has been hypothesised to cause "toxic pneumonitis" that should increase lung epithelial permeability at the bronchioloalveolar level. Serum Clara cell protein (CC16) and serum surfactant protein B (SPB) have been proposed as sensitive markers of lung epithelial injury. This study was aimed at looking for increased lung epithelial permeability by determining CC16 and SPB in workers exposed to bioaerosols from wastewater or garbage. METHODS: Subjects (778 wastewater, garbage and control workers; participation 61%) underwent a medical examination, lung function tests [American Thoracic Society (ATS) criteria], and determination of CC16 and SPB. Symptoms of endotoxin exposure and several potential confounders (age, gender, smoking, kidney function, obesity) were looked for. Results were examined with multiple linear or logistic regression. RESULTS: Exposure to bioaerosols increased CC16 concentration in the wastewater workers. No effect of exposure on SPB was found. No clue to work-related respiratory diseases was found. CONCLUSIONS: The increase in CC16 in serum supports the hypothesis that bioaerosols cause subclinical "toxic pneumonitis", even at low exposure. [Authors]

Organisational PSM Antecedents. Do HRM Practices Matter? Testing the Mediating Role of Job Satisfaction and Organisational Commitment

The present study aims to identify organisational antecedents of public service motivation (PSM). Numerous research has been devoted to the identification of socio-demographic PSM antecedents, or to its outcomes. However, organisational antecedents are understudied thus far. In order to fill this research gap, we question whether human resources management practices, whether intrinsic or extrinsic ones, might be related to PSM. Drawing on person-environment fit theoretical assumptions, we depart from the idea that PSM may be developed or sustained by HRM practices, which might contribute to create an environment allowing public employees to fulfill their needs or personal aspirations. Based upon a survey in an important Swiss municipality (N = 859), our findings surprisingly highlight that extrinsic HRM practices are significantly related to PSM, whereas intrinsic ones are not. Furthermore, when taking into account work-related outcomes, such as job satisfaction and organisational commitment, there is evidence of full mediation effects towards extrinsic HRM practices from organisational commitment. Astonishingly, neither job satisfaction nor intrinsic HRM practices are significantly related to PSM.

Couples' Resolution of an Infertility Diagnosis Before Undergoing in Vitro Fertilization

Although the use of assisted reproductive technology has today become more familiar, the suffering associated with the experience of infertility remains. This study assesses the emotional resolution of couples faced with an infertility diagnosis by examining their narratives. Fifty-seven couples were recruited from fertility clinics to participate in a semistructured interview prior to in vitro fertilization. Two aspects of the couples' reactions to the infertility diagnosis were assessed: (1) each individual's capacity to acknowledge the emotional reality of the diagnosis (diagnosis resolution) and (2) the couple's ability to construct a shared meaning of the infertility diagnosis experience (narrative co-construction). Associations between these aspects and self-reported marital satisfaction, infertility-related stress, and diagnosis-related variables were analyzed. 73.7% of women and 61.4% of men had acknowledged the emotional reality of the diagnosis, and their scores for narrative co-construction were comparable to reference samples. Marital satisfaction, but not infertility-related stress, was associated with diagnosis resolution and narrative co-construction. The results indicate the importance of detecting couples with fewer individual and marital resources needed to face the reality of the diagnosis. A couple's capacity to perceive the infertility diagnosis as a shared problem is also essential for dealing with this common life event.

Quality of life after pulmonary embolism: validation of the French version of the PEmb-QoL questionnaire.

Background The PEmb-QoL is a validated 40-item questionnaire to quantify health-related quality of life in patients having experienced pulmonary embolism (PE). It covers six health dimensions: frequency of complaints, activities of daily living limitations, work-related problems, social limitations, intensity of complaints, and emotional complaints. Originally developed in Dutch and English, we sought to prospectively validate the psychometric properties of a French version of the PEmb-QoL.MethodsWe performed a forward and backward translation of the English version of the PEmb-QoL into French. French-speaking consecutive adult patients with an acute, objectively confirmed PE admitted to the emergency department of a Swiss university hospital between 08/2009 and 09/2011 were recruited telephonically. We used standard psychometric tests and criteria to evaluate the acceptability, reliability, and validity of the French version of the PEmb-QoL. We also performed an exploratory factor analysis.ResultsOverall, 102 patients were enrolled in the study. The French version of the PEmb-QoL showed good reliability (internal consistency, item¿total and inter-item correlations), reproducibility (test-retest reliability), and validity (convergent, discriminant) in French-speaking patients with PE. The exploratory factor analysis suggested three underlying dimensions: limitations in daily activity (items 4b-m, 5a-d), symptoms (items 1a-h and 7), and emotional complaints (items 9a-f and j).ConclusionWe successfully validated the French version of the PEmb-QoL questionnaire in patients with PE. Our results show that the PEmb-QoL is a valuable tool for assessing health-related quality of life after PE in French-speaking patients.

Diagnostic performance of urinary metanephrines for the postmortem diagnosis of hypothermia.

The purpose of this study was to assess the diagnostic potential of urinary metanephrines and 3-methoxytyramine compared to urinary catecholamine determination in diagnosing antemortem cold exposure and fatal hypothermia. 83 cases of fatal hypothermia and 144 control cases were included in this study. Catecholamines (adrenaline, noradrenaline and dopamine), metanephrines (metanephrine, normetanephrine) and 3-methoxytyramine were measured in urine collected during autopsy. All tested analytes were significantly higher in hypothermia cases compared to control subjects and displayed a generally satisfying discriminative value, thus indicating urinary catecholamines and their metabolites as reliable markers of cold-related stress and hypothermia related-deaths. Metanephrine and adrenaline had the best discriminative value between hypothermia and control cases compared to other tested analytes, though with different sensitivity and specificity. These can therefore be considered the most suitable markers of cold-related stress.

Health problems of nursing workers in a public educational institution

Objective: To identify the issues occurred with nursing workers through a Health Monitoring System for Nursing Workers (SIMOSTE) and to describe the consequences of those problems. Method: This is a quantitative, exploratory and descriptive study realized in a teaching hospital in the west region of the city of São Paulo. Results: From the SIMOSTE, 1.847 occurrences were registered in a six month period. Within the main occurrences, medical licenses, work related accidents with and without removals; psychiatric consultations and psychotherapy were highlighted. Conclusion: The data points out to the need for the development of new health vigilance actions to notify accidents and illness related to work, besides the prevention of issues. 


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.

Factors influencing adherence to standard precautions among nursing professionals in psychiatric hospitals

OBJECTIVE Evaluate and correlate individual, work-related and organizational factors that influence adherence to standard precautions among nursing professionals of psychiatric hospitals in São Paulo. METHOD An exploratory cross-sectional study conducted with 35 nursing professionals, using the assessment tool for adherence to standard precautions through the Likert scale, ranging from 1 to 5. RESULTS Knowledge of the precautions received a high score (4.69); adherence received (3.86) and obstacles (3.78), while intermediaries and the scales of organizational factors received low scores (2.61). There was a strong correlation between the magnitude adherence scale and the personal protective equipment availability (r = 0.643; p = 0.000). The training scale for prevention of HIV exposure (p = 0.007) was statistically different between the nurses and nursing assistants. CONCLUSION The organizational factors negatively contributed to adherence to standard precautions, indicating that psychiatric institutions lack safe working conditions, ongoing training and management actions to control infections.

Burned-out but proud Portuguese family doctors

Background: Burnout syndrome (BS) is increasing among health professionals, including family doctors (FD). Aim: To characterize the prevalence of BS in a sample of FDs working in the Portuguese National Health System. Design: Cross-sectional survey. Setting: Primary Health Care Centers (HCC) from the 18 continental districts and 2 archipelagos of Portugal. Method: The Portuguese version of the Maslach Burnout Inventory - Human Services Survey (MBI - HSS) was sent to 40 randomly selected health-care centers (HCC) and distributed to the FDs employed. Sociodemographic and work-related data was also collected. Participants were classified as having high, average or low levels of emotional exhaustion (EE), depersonalization (DP) and personal accomplishment (PA) dimensions of burnout. Results: 371 questionnaires were sent, of which 153 (83 women, age range 29-64 years; response rate 41%) returned. One quarter (25.5%) of participants had high EE, 10.1% high DP and 11.4% high PA, but only 2.0% of participants scored high for all three dimensions. Women had significantly higher DP and PA scores than men; increased daily workload also led to increased PA scores. Conversely, no association was found between BS scores and age, marital status, number of years of practice or type of HCC (Family or Personalized). Conclusion: High burnout is relatively common among Portuguese family doctors, yet slightly lower than reported for other European countries. Burnout relief measures should be developed in order to prevent a further increase of BS among Portuguese FDs.

Exposure of highway maintenance workers to fine particulate matter and noise

In this study, we assessed the mixed exposure of highway maintenance workers to airborne particles, noise, and gaseous co-pollutants. The aim was to provide a better understanding of the workers' exposure to facilitate the evaluation of short-term effects on cardiovascular health endpoints. To quantify the workers' exposure, we monitored 18 subjects during 50 non-consecutive work shifts. Exposure assessment was based on personal and work site measurements and included fine particulate matter (PM2.5), particle number concentration (PNC), noise (Leq), and the gaseous co-pollutants: carbon monoxide, nitrogen dioxide, and ozone. Mean work shift PM2.5 concentrations (gravimetric measurements) ranged from 20.3 to 321 μg m(-3) (mean 62 μg m(-3)) and PNC were between 1.6×10(4) and 4.1×10(5) particles cm(-3) (8.9×10(4) particles cm(-3)). Noise levels were generally high with Leq over work shifts from 73.3 to 96.0 dB(A); the averaged Leq over all work shifts was 87.2 dB(A). The highest exposure to fine and ultrafine particles was measured during grass mowing and lumbering when motorized brush cutters and chain saws were used. Highest noise levels, caused by pneumatic hammers, were measured during paving and guardrail repair. We found moderate Spearman correlations between PNC and PM2.5 (r = 0.56); PNC, PM2.5, and CO (r = 0.60 and r = 0.50) as well as PNC and noise (r = 0.50). Variability and correlation of parameters were influenced by work activities that included equipment causing combined air pollutant and noise emissions (e.g. brush cutters and chain saws). We conclude that highway maintenance workers are frequently exposed to elevated airborne particle and noise levels compared with the average population. This elevated exposure is a consequence of the permanent proximity to highway traffic with additional peak exposures caused by emissions of the work-related equipment.

Temperature-induced sex reversal is not responsible for sex-ratio distortions in grayling Thymallus thymallus or brown trout Salmo trutta.

On the basis of the experiments carried out over various years, it was concluded that (1) grayling Thymallus thymallus and brown trout Salmo trutta are resistant to temperature-induced sex reversal at ecologically relevant temperatures, (2) environmental sex reversal is unlikely to cause the persistent sex ratio distortion observed in at least one of the study populations and (3) sex-specific tolerance of temperature-related stress may be the cause of distorted sex ratios in populations of T. thymallus or S. trutta.
