A contribution to the French validation of the clinical anxiety scale amongst health care workers in Switzerland.

BACKGROUND: Anxiety disorders are frequent but remain often underdiagnosed and undertreated. Hence, valid screening instruments are needed to enhance the diagnostic process. The Clinical Anxiety Scale (CAS) is a 25-item anxiety screening tool derived from the Hamilton Anxiety Scale (HAM-A). However, this scale is not available in French. The General anxiety disorder - 7 (GAD-7) scale, which has been validated in French, is a 7-item instrument with good psychometric properties. This study contributes to the validation of an adapted French version of the CAS, using the GAD-7 as the reference. METHODS: A forward-backward English-French-English translation of the CAS was performed according to standard practice. The French versions of the CAS and GAD-7 were completed by 127 French speaking healthcare professionals. CAS internal consistency was assessed using Crohnbach's alpha, and test-retest reliability was tested after 15 days in a subsample of 30 subjects. Convergent validity with GAD-7 was assessed using Pearson's correlation coefficient. Test-retest reliability was explored using one-way random effects model to calculate the intra-class correlation coefficient (ICC). RESULTS: French CAS showed excellent internal consistency (Cronbach's alpha 0.97), high convergent validity with GAD-7 (Pearson's R 0.81, p < 0.001), and very good test-retest reliability (ICC = 0.97, 95% CI 0.93-0.98). CONCLUSION: The proposed French version of the CAS showed high reliability and validity that need to be further investigated in different populations.

Association of adiposity evaluated by anthropometric, BIA, and DXA measures with cardiometabolic risk factors in nonobese postmenopausal women: the CoLaus/OsteoLaus cohort.

OBJECTIVE: After menopause, body composition changes with body fat accumulation, and an increase in cardiometabolic risk factors. Total fat mass, regional fat mass, and visceral adipose tissue (VAT) may be estimated with anthropometric measures, bioelectrical impedance analysis (BIA), and dual-energy X-ray absorptiometry (DXA). The aim of our study was to assess which measurement correlated best with cardiometabolic risk factors in healthy nonobese postmenopausal women. METHODS: The CoLaus/OsteoLaus cohort included 1,500 postmenopausal women (age range 50-80). We analyzed correlations between: 1) measurements of body composition assessed by anthropometric measures, BIA, and DXA and 2) these measurements and different selected cardiometabolic risk factors, such as blood pressure, lipid markers (cholesterol subtypes and triglycerides), and metabolic markers (glucose, insulin, adiponectin, and leptin). Spearman correlation coefficient, stepwise forward regression, and linear regression analyses were used to determine association between anthropometric measurements and cardiometabolic risk factors. RESULTS: In the 803 included participants (mean age 62.0 ± 7.1 y, mean body mass index 25.6 kg/m2 ± 4.4), correlations between total fat mass measured by BIA and total fat mass, android fat, gynoid fat, or VAT measured by DXA are very strong (from r = 0.531, [99% confidence interval (CI), 0.443-0.610] to r = 0.704, [99% CI, 0.640-0.758]). Body mass index and waist circumference have a higher correlation with VAT (r = 0.815, [99% CI, 0.772-0.851] and r = 0.823 [99% CI, 0.782-0.858], respectively) than BIA (r = 0.672 [99% CI, 0.603-0.731]). Among the anthropometric measurement and the measurements derived from DXA and BIA, VAT is the parameter most strongly associated with cardiometabolic risk factors. VAT better explains the variation of most of the cardiometabolic risk factors than age and treatment. For example, nearly 5% of the variability of the diastolic blood pressure (9.9 vs 4.9), nearly 15% of the variability of high-density lipoprotein cholesterol (20.3 vs 3.8) and triglyceride (21.1 vs 6.5), 25.3% of the variability of insulin (33.3 vs 8.1), and 37.5% of the variability of leptin (37.7 vs 1.1) were explained by VAT. CONCLUSIONS: BIA seems not to be a good tool to assess VAT. At the population level, waist circumference and body mass index seem to be good tools to estimate VAT. VAT measured by DXA is the parameter most correlated with cardiometabolic risk factors and could become a component of the cardiometabolic marker on its own.

Sleeping enough is associated with a reduced risk of mortality and dementia. New evidence support regular physical exercise, including at home, as a corner stone intervention to prevent falls and fractures. In contrast, supplementation with high doses of vitamin D is ineffective and even deleterious in this indication and a routine screening in asymptomatic adults is not recommended. Several studies illustrate our difficulties in prescribing and deprescribing in frail older patients and a study suggests that statins in cardiovascular primary prevention should considered only when a patient's life expectancy exceeds 2.5 years. Finally, several studies have fueled the debate about screening for hearing impairment.

Dormir ni trop ni trop peu est associé à une réduction du risque de mortalité et de déclin cognitif. De nouvelles études confirment que l'exercice physique régulier, y compris à domicile, constitue la clé de voûte de la prévention des chutes et des fractures. Par contre, la supplémentation par de hautes doses de vitamine D n'est pas efficace, voire délétère, dans cette indication et le dépistage systématique d'un déficit n'est pas recommandé chez les patients adultes asymptomatiques. Plusieurs études illustrent nos difficultés à prescrire et déprescrire, chez les patients âgés fragiles, et une étude suggère qu'un traitement de statines en prévention cardiovasculaire primaire ne se justifie que si l'espérance de vie du patient dépasse 2,5 ans. Finalement, plusieurs études sont venues nourrir le débat sur le dépistage de la presbyacousie.

In 2018, new recommendations about the prevention of falls and fractures emphasized the benefits from exercise and from multimodal prevention programs but did not endorse any more vitamin D supplementation for falls prevention. Results were contrasted for several studies testing exercise (negative) and cognitive training (mixed results) in the management of older patients suffering from neurocognitive disorders. The new direct oral anticoagulants are increasingly prescribed in older patients despite the paucity of data. New information has been released in 2018 from « real-world ¼ data that seem reassuring about their risk/benefit ratio in old-old patients, provided a careful prescription. Finally, the Mediterranean diet is still gaining credit with a new study showing its benefits in preventing frailty in community-dwelling older persons.

En 2018, l'intérêt de l'activité physique et des programmes de prévention multimodaux est confirmé pour la prévention des chutes, mais l'utilisation de la vitamine D dans cette indication est remise en question. Pour les pathologies neurocognitives, les résultats sont contrastés concernant l'activité physique, alors qu'une revue systématique confirme les bénéfices, certes modestes, de l'entraînement cognitif sur les performances cognitives et la qualité de vie des patients et de leurs proches. Les nouveaux anticoagulants sont de plus en plus largement utilisés chez les patients âgés malgré des données encore limitées, mais plusieurs études du « monde réel ¼ semblent confirmer leur bon rapport risques/bénéfices aussi chez ces patients. Le régime méditerranéen a le vent en poupe, une étude rapporte un bénéfice sur l'incidence de la fragilité.

[Screening and management of malnutrition in internal medicine]. / Dépistage et prise en charge de la dénutrition en médecine interne hospitalière.

Malnutrition is a common but underestimated condition in the hospital setting. Malnutrition increases in-hospital mortality and complications, and treatment costs. Simple screening tools such as the mini-nutritional assessment and the nutritional risk score allow identifying patients at risk of malnutrition and starting management. Malnutrition management is a multidisciplinary issue including dieticians, physiatrists, nurses, caregivers and doctors. Meal fractioning and oral nutritional supplements (ONS) should be provided. Frequently, micronutrient supplements are also needed. Particular care should be taken to ensure that the patient consumes the meals and ONS prescribed. Follow-up is based on weight and assessment of prealbumin. Malnutrition status should be systematically reported in the discharge letter.

La dénutrition est fréquente à l'hôpital mais sous-estimée. Elle augmente la mortalité, les complications intrahospitalières, ainsi que les coûts du traitement. Des outils de dépistage tels que le mini-nutritional assessment et le nutritional risk score permettent d'identifier les patients à risque de dénutrition. La prise en charge implique une équipe interprofessionnelle (diététiciennes, physiothérapeutes, infirmières, aides-soignantes et médecins) et se base sur le fractionnement des repas, associé à des suppléments nutritionnels oraux (SNO) adaptés et à des suppléments en micronutriments. Une attention particulière portera sur la consommation effective des repas et des SNO. Le suivi nutritionnel sera complété par la mesure du poids et le dosage de la préalbumine. La documentation dans la lettre de sortie devrait être systématique.
