Vieillir et devenir vulnérable [Aging and becoming vulnerable].

"The vulnerable are those whose autonomy, dignity and integrity are capable of being threatened". Based on this ethical definition of vulnerability, four risk factors of vulnerability might be identified among elderly persons, and are described in this article: the functional limitation, the loss of autonomy, the social precariousness and the restriction of access to medical care. A clinical case of elderly abuse is presented to illustrate vulnerability. Finally, some recommendations to lower the risk of vulnerability in elderly persons are proposed.

Quelle organisation des soins pour le patient polymorbide? [How should we organize health care for multimorbidity patients?].

Polymorbidity affects an increasing number of patients of all ages as demonstrated by a recent epidemiological study and represents a real challenge for the organization of health care. Appropriate management of polymorbid patients requires an interdisciplinary approach associating generalist and specialist physicians, but also nurses, other health professionals and social workers. An improvement in transition care between the community and the hospital is necessary in both directions. Prioritizing the treatment objectives is essential to allow patient adherence and avoid cumulative drug interactions and adverse effects. Those objectives are difficult to attain in the context of our present health care organization. This paper attempts to identify the difficulties involved in caring for polymorbid patients and propose ways to improve it.

Respiratory effects of an exposure to wheat dust among grain workers and farmers: a longitudinal study

OBJECTIVES: Agriculture is considered one of the occupations most at risk of acute or chronic respiratory problems. The aim of our study was to determine from which level of exposure to organic dust the respiratory function is chronically affected in workers involved in wheat grain or straw manipulation and to test if some of these working populations can recover their respiratory function after an exposure decrease. METHOD: 87 workers exposed to wheat dust: farmers, harvesters, silo workers and livestock farmers and 62 non exposed workers, were included into a longitudinal study comprising two visits at a six months interval with lung function measurements and symptom questionnaires. Cumulative and mean exposure to wheat dust were generated from detailed work history of each worker and a task-exposure matrix based on task-specific exposure measurements. Immunoglobulins (IgG and IgE) specific of the most frequent microorganisms in wheat dust have been determined. RESULTS: FEV1 decreased significantly with the cumulative exposure and mean exposure levels. The estimated decrease was close to 200 mL per year of high exposure, which corresponds roughly to levels of wheat dust higher than 10 mg/m(3). Peak expiratory flow and several acute symptoms correlate with recent exposure level. Recovery of the respiratory function six months after exposure to wheat dust and evolution of exposure indicators in workers blood (IgG and IgE) will be discussed. CONCLUSIONS: These results show a chronic effect of exposure to wheat dust on bronchial obstruction. Short term effects and reversibility will be assessed using the full study results.

Exhaled breath condensate as a matrix for combustion-based nanoparticle exposure and health effect evaluation

Health assessment and medical surveillance of workers exposed to combustion nanoparticles are challenging. The aim was to evaluate the feasibility of using exhaled breath condensate (EBC) from healthy volunteers for (1) assessing the lung deposited dose of combustion nanoparticles and (2) determining the resulting oxidative stress by measuring hydrogen peroxide (H2O2) and malondialdehyde (MDA). Methods: Fifteen healthy nonsmoker volunteers were exposed to three different levels of sidestream cigarette smoke under controlled conditions. EBC was repeatedly collected before, during, and 1 and 2 hr after exposure. Exposure variables were measured by direct reading instruments and by active sampling. The different EBC samples were analyzed for particle number concentration (light-scattering-based method) and for selected compounds considered oxidative stress markers. Results: Subjects were exposed to an average airborne concentration up to 4.3×10(5) particles/cm(3) (average geometric size ∼60-80 nm). Up to 10×10(8) particles/mL could be measured in the collected EBC with a broad size distribution (50(th) percentile ∼160 nm), but these biological concentrations were not related to the exposure level of cigarette smoke particles. Although H2O2 and MDA concentrations in EBC increased during exposure, only H2O2 showed a transient normalization 1 hr after exposure and increased afterward. In contrast, MDA levels stayed elevated during the 2 hr post exposure. Conclusions: The use of diffusion light scattering for particle counting proved to be sufficiently sensitive to detect objects in EBC, but lacked the specificity for carbonaceous tobacco smoke particles. Our results suggest two phases of oxidation markers in EBC: first, the initial deposition of particles and gases in the lung lining liquid, and later the start of oxidative stress with associated cell membrane damage. Future studies should extend the follow-up time and should remove gases or particles from the air to allow differentiation between the different sources of H2O2 and MDA.

The effect of workplace smoking bans on heart rate variability and pulse wave velocity of non-smoking hospitality workers

OBJECTIVES: To investigate the effect of a change in second-hand smoke (SHS) exposure on heart rate variability (HRV) and pulse wave velocity (PWV), this study utilized a quasi-experimental setting when a smoking ban was introduced. METHODS: HRV, a quantitative marker of autonomic activity of the nervous system, and PWV, a marker of arterial stiffness, were measured in 55 non-smoking hospitality workers before and 3-12 months after a smoking ban and compared to a control group that did not experience an exposure change. SHS exposure was determined with a nicotine-specific badge and expressed as inhaled cigarette equivalents per day (CE/d). RESULTS: PWV and HRV parameters significantly changed in a dose-dependent manner in the intervention group as compared to the control group. A one CE/d decrease was associated with a 2.3 % (95 % CI 0.2-4.4; p = 0.031) higher root mean square of successive differences (RMSSD), a 5.7 % (95 % CI 0.9-10.2; p = 0.02) higher high-frequency component and a 0.72 % (95 % CI 0.40-1.05; p < 0.001) lower PWV. CONCLUSIONS: PWV and HRV significantly improved after introducing smoke-free workplaces indicating a decreased cardiovascular risk.

Symptoms of chronic stress at work in NGO workers

Working in a NGO often involves providing life saving resources (food, medicine, equipment, water, etc) to needy populations around the globe. Such duty requires highly dedicated employees and humanitarian workers are said to face a hign degree of pressure in their daily work. Despite the evidence of taxing work demands, and a high potential for stress related problems, very few studies on occupational chronic stress have specifically looked at NGO workers. Assuming that "field stress" can relay to workers at headquarters, we carried out an exploratory study about occupational health among employees of a NGO's headquarters. We sent a questionnaire to all employees (N=130) of a NGO headquarters located in Switzerland. We used the TST questionnaire (French version of the Langner's questionnaire on psychiatric symptoms) to identify cases with potential mental health problems. We also included in the questionnaire some items about motivation, acknowledgment, work-life balance, job demand, and autonomy. A total of 75 employees answered our questionnaire (57% response rate). 44% of our sample were men (n=33) and 56% were women (n=42). The mean age was of 40 years (SD=7.6). 56% were working at the headquarters of the NGO in questions as of 2 years or less. Not surprisingly, a majority of respondents reported to be highly motivated (74%) and the meaning of work was important for 80% of them. However, 35% indicated having problems in conciliating their private and professional life. Most frequent reported symptoms included feeling "weak all over" (81%), having "trouble getting asleep often" (35%), "clogging in nose" (35%), feeling "nervous often" (33%), and "memory not all right" (33%). The score for psychiatric symptoms was high in 8 (11%) employees whose health might therefore be at risk. In comparison, other sudies showed that this proportion was 9% for French teachers and 16% for sales personnel1. Results show that symptoms of mental health problems do occur among NGO workers. Some of these symptoms are known to be linked to occupational stress. Chronic stress manifests itself first in non-specific symptoms (e.g. fatigue) and later in specific pathologies. This could explain the relatively low proportion of cases with a high score in Langner's scale than was expected. Therefore, we hypothesize a healthy worker effect. The fact that our sample is 40 years old in average, and that the turnover is quite high can also support this hypothesis. Further research is needed in order to better understand occupational stress in this specific population. An upcoming study will investigate the role of organizational factors associated with health complaints. Therefore, a longitudinal survey including quantitative and qualitative methods is appropriate.
