[Healthy aging in Geneva : the innovative approach of the VieSA project]. / Vieillir en santé à Genève : l'approche novatrice du projet VieSA.

With Switzerland's population ageing, promoting healthy ageing remains a public health issue. This represents a challenge for the healthcare system, which is still mainly focused on curative or palliative care. It has been clearly established that it is possible to maintain the functional capacity of older people by taking early action on health-related behaviors. The VieSA (Vieillissement en Santé) project in the canton of Geneva, inspired by the WHO's ICOPE programme, offers innovative ways of promoting healthy ageing for and by seniors, by focusing on maintaining seniors' resources rather than targeting any deficits.

Face au vieillissement de la population en Suisse, la promotion du vieillissement en santé reste un enjeu de santé publique. Cela représente un défi pour le système de soins encore principalement orienté vers les soins curatifs ou palliatifs. Il est clairement établi qu'il est possible de maintenir les capacités fonctionnelles des seniors en agissant précocement sur les comportements liés à la santé. Le projet VieSA (Vieillissement en santé), mené dans le canton de Genève, s'inspire du programme ICOPE de l'OMS et offre des perspectives novatrices pour promouvoir le vieillissement en santé pour et par les seniors, en s'appuyant sur le maintien des ressources des seniors plutôt qu'en ciblant les déficits éventuels.

Intrinsic Capacities, Functional Ability, Physiological Systems, and Caregiver Support: A Targeted Synthesis of Effective Interventions and International Recommendations for Older Adults.

The ageing population calls for interventions that can assist older people to age healthily. This study aimed to provide a targeted synthesis of high-level research and current evidence-based recommendations on effective interventions for maintaining or preventing the decline in intrinsic capacity, functional ability, and physiological systems, or for caregiver support. Nestled within the healthy ageing framework by the World Health Organization, available evidence was selected in a targeted manner, with the purpose of providing a synthesis that would allow the application of this knowledge in real life. As such, the outcome variables were examined through an Evidence and Gap Map of interventions for functional ability and through guidelines from leading institutions. Systematic reviews, meta-analyses, and guidelines on community-dwelling older adults with or without minor health limitations were considered. Thirty-eight documents were included and over fifty interventions identified. Physical activity interventions were consistently effective across several domains. Recommendations point to screening, whilst highlighting the importance of behavioural factors in the endeavour to age healthily. There is a wide range of activities which are likely to foster healthy ageing. To encourage their uptake, it is important for communities to offer suitable promotion and support, and to make these accessible to the public.

Delirium in Older Patients With COVID-19: Prevalence, Risk Factors, and Clinical Relevance.

BACKGROUND: Delirium prevalence increases with age and is associated with poor outcomes. We aimed to investigate the prevalence and risk factors for delirium in older patients hospitalized with COVID-19, as well as its association with length of stay and mortality. METHOD: This was a retrospective study of patients aged 65 years and older hospitalized with COVID-19. Data were collected from computerized medical records and all patients had delirium assessment at admission. Risk factors for delirium as well as the outcomes mentioned above were studied by 2-group comparison, logistic regression, and Cox proportional hazard models. RESULTS: Of a total of 235 Caucasian patients, 48 (20.4%) presented with delirium, which was hypoactive in 41.6% of cases, and hyperactive and mixed in 35.4% and 23.0%, respectively. Patients with cognitive impairment had a nearly 4 times higher risk of developing delirium compared to patients who were cognitively normal before SARS-CoV-2 infection (odds ratio 3.7; 95% CI: 1.7-7.9, p = .001). The presence of delirium did not modify the time from symptoms' onset to hospitalization or the length of stay in acute care, but it was associated with an increased risk of dying (hazard ratio 2.1; 95% CI: 1.2-3.7, p = .0113). CONCLUSION: Delirium was a prevalent condition in older people admitted with COVID-19 and preexisting cognitive impairment was its main risk factor. Delirium was associated with higher in-hospital mortality. These results highlight the importance of early recognition of delirium especially when premorbid cognitive comorbidities are present.

[Issues and challenges related to COVID-19 in acute geriatric care: lessons learned from the Geneva experience]. / Enjeux et défis du Covid-19 en gériatrie aiguë: leçons tirées de l'expérience genevoise.

The older patients have been the most affected by the SARS-CoV-2 pandemic. In addition, this infection has been responsible for high mortality rate in this population. In this article we wanted to describe the clinical findings we encountered in older people with COVID-19 and share some of the issues and challenges we faced during the COVID-19 pandemic.

Les personnes âgées ont été les plus touchées par la pandémie de SARS-CoV-2. De plus, cette infection a été responsable d'une mortalité élevée au sein de cette population. Dans cet article, nous avons souhaité décrire les particularités cliniques du Covid-19 que nous avons constatées chez les patients âgés et faire part de plusieurs enjeux et défis auxquels nous avons été confrontés au cours de la pandémie de Covid-19.

Predictors of In-Hospital Mortality in Older Patients With COVID-19: The COVIDAge Study.

OBJECTIVE: To determine predictors of in-hospital mortality related to COVID-19 in older patients. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Patients aged 65 years and older hospitalized for a diagnosis of COVID-19. METHODS: Data from hospital admission were collected from the electronic medical records. Logistic regression and Cox proportional hazard models were used to predict mortality, our primary outcome. Variables at hospital admission were categorized according to the following domains: demographics, clinical history, comorbidities, previous treatment, clinical status, vital signs, clinical scales and scores, routine laboratory analysis, and imaging results. RESULTS: Of a total of 235 Caucasian patients, 43% were male, with a mean age of 86 ± 6.5 years. Seventy-six patients (32%) died. Nonsurvivors had a shorter number of days from initial symptoms to hospitalization (P = .007) and the length of stay in acute wards than survivors (P < .001). Similarly, they had a higher prevalence of heart failure (P = .044), peripheral artery disease (P = .009), crackles at clinical status (P < .001), respiratory rate (P = .005), oxygen support needs (P < .001), C-reactive protein (P < .001), bilateral and peripheral infiltrates on chest radiographs (P = .001), and a lower prevalence of headache (P = .009). Furthermore, nonsurvivors were more often frail (P < .001), with worse functional status (P < .001), higher comorbidity burden (P < .001), and delirium at admission (P = .007). A multivariable Cox model showed that male sex (HR 4.00, 95% CI 2.08-7.71, P < .001), increased fraction of inspired oxygen (HR 1.06, 95% CI 1.03-1.09, P < .001), and crackles (HR 2.42, 95% CI 1.15-6.06, P = .019) were the best predictors of mortality, while better functional status was protective (HR 0.98, 95% CI 0.97-0.99, P = .001). CONCLUSIONS AND IMPLICATIONS: In older patients hospitalized for COVID-19, male sex, crackles, a higher fraction of inspired oxygen, and functionality were independent risk factors of mortality. These routine parameters, and not differences in age, should be used to evaluate prognosis in older patients.

[2016 Update in general internal medicine : Good intentions, possible bad outcomes]. / Bonnes intentions, possibles résultats défavorables.

Ideally, our clinical practices and decisions should be based on evidence derived from randomized clinical trials. Yet, we often have to determine the potential side effects (including interactions) of drugs that we prescribed using other level of evidence; clinical trials being obviously not appropriate for such situations. Results from observational studies published in 2016 should be of interest to primary care physicians. In this review, we present six of them. Once the limitations of these non-interventional studies acknowledged, primary care physicians should consider these results and be particularly attentive when prescribing these drugs.

Dans l'idéal, nos pratiques et décisions sont guidées sur la base d'évidences issues d'études cliniques randomisées. Cependant, nous devons fréquemment juger des possibles effets indésirables (y inclus interactions) des médicaments que nous prescrivons sur la base d'autres types d'informations, les essais cliniques n'étant pour des raisons évidentes pas réalisables. Les résultats de plusieurs études observationnelles publiées en 2016 dans ce domaine devraient attirer notre attention. Nous présentons ici six d'entre elles. Une fois les limites inhérentes à ce type d'étude considérées, ces résultats nous invitent à être particulièrement vigilants lors de nos prescriptions.

[New professional field in France: Analysis of the training needs of case managers]. / Nouveau champ professionnel en France. Les besoins de formation des gestionnaires de cas.

Case management is a relatively new career field in France. It was first introduced on an experimental basis in 2007-2008, and was then developedfollowing the National Alzheimer Plan and finally enshrined in legislation in 2012. This careerfield is based on a set of tasks widely described internationally: identifying the right level of intervention, standardized multidimensional assessment, planning all aid (care and social services), implementation of the plan, monitoring and reassessment and periodic reassessment of all needs in a continuous and long-term process. The specific, systematic and dedicated nature of these tasks to these tasks makes training essential. Regulations also stipulate that the professional must acquire additional training by a dedicated inter-university degree. This requirement is a French specificity The authors present the history of case management and training in France and analyze the various international training frameworks identified by an Internet search. Moreover, based on the opinions expressed by case managers at different times of the scientific assessment and a review ofseveral studies conducted by inter-university case management program students, this article highlights the specific training needs of case managers and how the proposed training can meet these needs.

[Bullous pemphigoid: a cutaneous disorder to be known in aging persons]. / Pemphigoïde bulleuse: une dermatose du grand age a mieux connaître.

Bullous pemphigoid is a rare autoimmune muco-cutaneous disorder involving particularly aged adults. Its incidence may be underestimated. Recent studies show the various clinical presentations that may delay diagnosis up to several years in absence of typical bullous presentation. Diagnosis such as skin adverse event or infection should be quickly eliminated and the autoimmunity confirmed with skin and blood immunology and pathology analysis. Any chronic pruritis or persisting blister in old people should lead to the diagnosis procedures of a bullous pemphigoid.

Identification of pathway-biased and deleterious melatonin receptor mutants in autism spectrum disorders and in the general population.

Melatonin is a powerful antioxidant and a synchronizer of many physiological processes. Alteration of the melatonin pathway has been reported in circadian disorders, diabetes and autism spectrum disorders (ASD). However, very little is known about the genetic variability of melatonin receptors in humans. Here, we sequenced the melatonin receptor MTNR1A and MTNR1B, genes coding for MT1 and MT2 receptors, respectively, in a large panel of 941 individuals including 295 patients with ASD, 362 controls and 284 individuals from different ethnic backgrounds. We also sequenced GPR50, coding for the orphan melatonin-related receptor GPR50 in patients and controls. We identified six non-synonymous mutations for MTNR1A and ten for MTNR1B. The majority of these variations altered receptor function. Particularly interesting mutants are MT1-I49N, which is devoid of any melatonin binding and cell surface expression, and MT1-G166E and MT1-I212T, which showed severely impaired cell surface expression. Of note, several mutants possessed pathway-selective signaling properties, some preferentially inhibiting the adenylyl cyclase pathway, others preferentially activating the MAPK pathway. The prevalence of these deleterious mutations in cases and controls indicates that they do not represent major risk factor for ASD (MTNR1A case 3.6% vs controls 4.4%; MTNR1B case 4.7% vs 3% controls). Concerning GPR50, we detected a significant association between ASD and two variations, Delta502-505 and T532A, in affected males, but it did not hold up after Bonferonni correction for multiple testing. Our results represent the first functional ascertainment of melatonin receptors in humans and constitute a basis for future structure-function studies and for interpreting genetic data on the melatonin pathway in patients.

[Ekbom syndrome or delusional parasitosis]. / Une fausse ectoparasitose: le syndrome d'Ekbom.

Ekbom syndrome or delusional parasitosis is mainly described in presenile women who are unmarried or living alone. The presenting dermatological symptom is persistent pruritus, and the patients take medical advice in several practitioners one after another. The typical symptom is the behaviour of bringing sample of the allegered parasites inside small containers, defined as the "matchbox sign". The patient is so convincing that she shares delusion of infestation by his familiars who complaint of pruritus. The Ekbon syndrome is defined as the most contagious of psychiatric syndromes. Beyond psychotherapy, pimozide is the drug of choice in such a syndrome.

[Management of blood eosinophilia in an outpatient clinic for tropical diseases]. / Prise en charge des hyperéosinophilies sanguines dans une consultation de maladies tropicales.

OBJECTIVE: We assessed the frequency of parasitic diseases and the efficacy of presumptive treatment when no cause was found. MATERIALS AND METHODS: This prospective study took place in the Tropical Disease department of Bicêtre Hospital over a two-year period and included patients with eosinophil counts exceeding 500/mm(3). RESULTS: The study included 117 patients with blood eosinophilia. A parasitic infection was identified for 48 (41%), and appropriate treatment resulted in a return to normal eosinophil counts for all of them. No parasite was identified in 45 patients (38.5%), but parasitic disease was suspected on the basis of clinical or epidemiologic evidence. These patients received presumptive treatment with antiparasitic drugs (ivermectin, albendazole and praziquantel, alone or in combination). Of the 30 patients in this group not lost to follow-up, eosinophil counts returned to normal for 20. Finally, a cause other than parasitosis was suspected for 15 of the 117 patients (13%): 9 (7.5%) of them were lost to follow-up. DISCUSSION: Parasites remain the leading cause of blood eosinophilia. Because the sensitivity of additional testing for these parasites is low and these antiparasitic drugs are safe (except for patients with loiasis), presumptive treatment appears appropriate.
