Effectiveness of light paths coupled with personal emergency response systems in preventing functional decline among the elderly.

INTRODUCTION: The elderly population is at high risk of functional decline, which will induce significant costs due to long-term care. Dependency could be delayed by preventing one of its major determinants: falls. Light paths coupled with personal emergency response systems could prevent the functional decline through fall prevention. METHODS: This study aimed to evaluate the effectiveness of light paths coupled with personal emergency response systems on the functional decline in an elderly population living at home. It is a secondary analysis on data from a previous cohort. In all, 190 older adults (aged 65 years or more) living at home participated. Participants in the exposed group were equipped with home-based technologies: light paths coupled with personal emergency response systems. The participants' functional status was assessed using the Functional Autonomy Measurement System scale at baseline (T0) and at the end of the study (T12-month). Baseline characteristics were evaluated by a comprehensive geriatric assessment. RESULTS: After 1 year, 43% of the unexposed group had functional decline versus 16% of the exposed group. Light paths coupled with personal emergency response systems were significantly associated with a decrease in the functional decline (Δ Functional Autonomy Measurement System ⩾ 5) at home (odds ratio = 0.24, 95% confidence interval (0.11-0.54), p = 0.002). DISCUSSION: This study suggests that light paths coupled with personal emergency response systems prevent the functional decline over 12 months. This result may encourage the prescription and use of home-based technologies to postpone dependency and institutionalization, but they need a larger cost-effectiveness study to demonstrate the efficiency of these technologies.

Epilepsy: Asia versus Africa.

Is epilepsy truly an "African ailment"? We aimed to determine this, since international health agencies often refer to epilepsy as an African disease and the scientific literature has spoken the same tone. Various published materials, mainly reports, articles, were used to gather Asian and African evidence on various aspects of epilepsy and many of its risk and associated factors. Our results suggest that in no way can epilepsy be considered as an African ailment and such characterization is most likely based on popular beliefs rather than scientific evidence. In comparison to Africa, Asia has a 5.0% greater burden from all diseases, and is 17.0% more affected from neuropsychiatric disorders (that include epilepsy). Given that more countries in Asia are transitioning, there may be large demographic and lifestyle changes in the near future. However these changes are nowhere close to those expected in Africa. Moreover, 23 million Asians have epilepsy in comparison to 3.3 million Africans and 1.2 million sub-Saharan Africans. In comparison to Africa, Asia has more untreated patients, 55.0% more additional epilepsy cases every year, because of its larger population, with greater treatment cost and possibly higher premature mortality. Of several associated factors discussed herein, many have more importance for Asia than Africa. The current state of epilepsy in Asia is far less than ideal and there is an urgent need to recognize and accept the importance of epilepsy in Asia. In no way can epilepsy be considered as an African ailment. This is most likely based on popular beliefs rather than scientific evidence.

First-ever population-based study on status epilepticus in French Island of La Reunion (France) - incidence and fatality.

PURPOSE: We aimed to determine the incidence and case-fatality of first-ever status epilepticus (SE) among the general population living in La Reunion Island, a French overseas territory in the Indian Ocean near Madagascar. METHODS: We recruited cases (1st July 2004-30th June 2005) in a population-based manner using neurology, neurosurgery, electroencephalogram, emergency, paediatric and neuroradiology services; emergency medical aid service; emergency and admission service of private and public clinics; neurologists (public and private); private paediatricians and practitioners of various rural hospitals. All cases had an electroencephalogram (EEG) and were assessed by an epileptologist. Standard definition and classification schemes were used. Those with known epilepsy were not part of this analysis. RESULTS: Sixty-five cases (males: n=41, 63.1%) had epileptologist-confirmed SE, with 38.5% (n=25) being >60 years of age. Global incidence rate was 8.52/100 000 (95% confidence interval 6.5-10.5). A bimodal age distribution with high frequency and incidence among young (<10 years age) (frequency: 12.3%; incidence 6.6/100,000) and aged (>60 years) (frequency: 40.0%; incidence 35.0/100,000) was observed. We found that 60%, 32.3%, 6.7% had convulsive, partial and non-convulsive SE respectively (1% remained unclassified). Of the cases identified, 44.6%, 38.5%, 16.9% had unprovoked, provoked or cryptogenic seizures respectively. The most important aetiological factors identified included: stroke (27.7%), alcoholism/toxicity (18.5%), cryptogenic (16.9%), infections (10.8%). Mortality was 18.5%. CONCLUSION: The incidence of SE incidence in La Reunion Island was lower than that described elsewhere. The status type was found to be dependent on aetiology and age. The study confirms that SE is more frequent in men and in older adults and is associated with significant short-term case mortality.

Newly-diagnosed epileptic seizures in three populations: Geneva (EPIGEN), Martinique (EPIMART), and the Reunion Island (EPIREUN).

AIM: The objective was to analyse and discuss data from three studies of newly-diagnosed epileptic seizures (provoked and unprovoked) conducted in Geneva, Martinique, and the Reunion Island, in which the same methodology was used. METHODS: We extracted data from three studies in which the incidence of seizures was estimated and aetiologies identified. Data was extracted and analysed using STATA. Group comparison was performed firstly for each study as a single group, and secondly by considering Martinique and the Reunion Island as an overseas group, in comparison with Geneva, considered as a mainland group. Uncorrected χ(2)was used and statistical significance (two-sided, p=0.05) was determined for each aetiology per cohort. RESULTSThe incidence of newly-diagnosed epileptic seizures per 100,000 was 71.0, 80.6, and 100.4 in Geneva, Martinique, and the Reunion Island, respectively. A bimodal distribution and predominance of generalised seizures was noted. The male to female ratio was higher in Martinique (∼2.0) than other populations (∼1.5). Status epilepticus was noted in Geneva and more so in the Reunion Island. The incidence of provoked seizures per 100,000 was 25.2, 16.4, and 17.7, and for unprovoked seizures was 45.6, 64.1, and 81.2 in Geneva, Martinique, and the Reunion Island, respectively. There was a greater risk of provoked seizures in Geneva relative to the overseas group, which was due to tumours, use of toxic substances, and drug abuse. The risk of unprovoked seizures in Geneva was due to trauma and infections. In Martinique, alcoholism and HIV were foremost factors for provoked and unprovoked seizures, and stroke was an important aetiology in both Martinique (provoked seizures) and the Reunion Island (unprovoked seizures). CONCLUSION: The risk of provoked seizures was greatest in Geneva and risk of unprovoked seizures was greatest in the Reunion Island. Toxic substances, alcohol, infection, and trauma constituted major factors for epileptic seizures in Geneva, while alcoholism, HIV, and stroke were major factors in the overseas group. Relative eradication of tropical infections has paved a way for the emergence of non-communicable aetiologies (stroke, alcoholism). Males from Martinique demonstrated the greatest risk of epileptic seizures, signifying the importance of alcoholism, HIV, etc. Three steps should follow: follow-up studies (mortality), strong mechanisms for prevention (or control) of risk factors, guidelines on whether to treat or not.

Assessment of palliative care for advanced non-small-cell lung cancer in France: a prospective observational multicenter study (GFPC 0804 study).

INTRODUCTION: Few studies assessed, in real life, symptoms, specific interventions and factors influencing palliative care (PC) initiation for patients with advanced non-small-cell lung cancer (NSCLC). The objective of this study was to examine, in a prospective cohort of advanced NSCLC patients, PC use and factors associated with early (≤3 months after diagnosis) PC initiation. METHODS: It was an observational multicenter study. Each center included 10 consecutive patients with PC initiation. RESULTS: 514 patients were enrolled by 39 centers (age: 62.3 ± 10.7 years, performance status: 0/1; 68.6% cases). At baseline, the most frequent symptoms concerned pain (43.6%), malnutrition (37%) and psychological disorders (25.3%). Specific interventions were infrequent for pain control and malnutrition, but were more numerous for psychological and social problems and terminal care. Median time between diagnosis and PC initiation was 35 [13-84] days, median PC duration was 4.2 [0.6-9.3] months. Median overall survival was 8.6 [6.6-10.7] months; median survival after PC initiation was 3.6 [3.2-4.5] months. In multivariate analysis, only PS ≥2 was linked to early PC. CONCLUSION: This study showed that early PC initiation is not a standard for patients with advanced NSCLC.

Efficacy of simple home-based technologies combined with a monitoring assistive center in decreasing falls in a frail elderly population (results of the Esoppe study).

BACKGROUND: Increasing age often implies increasing frailty, and the oldest old are often described as a frail group with a high risk of developing functional impairments and multi-morbidities like falls at home, which often result in dependence in daily activities. This preliminary study evaluate the efficacy of light path coupled with tele-assistance service for preventing unintentional falls at home in a frail elderly population. METHODS: Study design is a longitudinal prospective cohort study from 1st July 2009 to 30 June 2010. The program included 194 adults aged 65 and over living at home and registered on a list of frail elderly people. Participants were uniformly asked about their history of falls during the year prior to their most recent health examination. The recall period was one year. RESULTS: We observed that 77 (40.5%) elderly fell at home, 29 (30.9%) in the exposed group and 48 (50.0%) in the unexposed group. The use of light path coupled with tele-assistance was significantly associated with the reduction in falls at home, odd ratio=0.33 95%CI [0.17-0.65] p value=0.0012. There was also a greater reduction in post-fall hospitalization rate among exposed group with odd ratio=0.30 95%CI [0.12-0.74] p value=0.0091. CONCLUSIONS: This preliminary study showed that the use of light path coupled with tele-assistance service significantly reduced the incidence of unintentional falling at home among frail elderly population. This result should be confirmed by a randomized trial.

Newly diagnosed epileptic seizures: focus on an elderly population on the French island of Réunion in the Southern Indian Ocean.

PURPOSE: To describe seizure types and risk factors among elderly people with newly diagnosed epileptic seizures living on La Réunion, a French Island in the Southern Indian Ocean. METHODS: We describe an elderly population with newly diagnosed epileptic seizures using data from the EPIREUN study conducted between July 1, 2004 and June 30, 2005. The methodology is described in detail in the EPIREUN study report (Mignard et al., 2009). KEY FINDINGS: There were 153 single unprovoked seizures (84.1%); their incidence was 278.1 [95% confidence interval (CI) 237.4-325.9] per 100,000. The incidence of newly diagnosed epilepsy was 125.4 (95% CI, 99.1-158.8) per 100,000. Twenty-eight acute symptomatic seizures occurred (15.4%); the incidence was 50.9 (95% CI 35.1-73.7) per 100,000. The annual incidence of newly diagnosed epileptic seizure in the elderly was 330.8 (95% CI 286.1-382.6) per 100,000: 403.0 (95% CI 328.5-494.3) per 100,000 in men and 279.6 (95% CI, 227.4-343.8) per 100,000 in women. Sex had a significant (p = 0.014) effect on incidence: elderly men had a risk ratio of 1.44 compared to women of developing a newly diagnosed epileptic seizure. The etiology of single unprovoked seizure was as follows: stroke, 77 cases (50.3%); cryptogenic, 36 (23.5%); alcoholism, 10 (6.6%); a combination of several causes such as polypathology, 9 (5.9%); degenerative disease, 6 (4.0%); HIV infection, 2 (2.0%), and undetermined causes (2.7%). Most patients (170; 93.4%) were hospitalized, and 110 (60.8%) were treated. Among patients treated, 49 (44.5%) were given sodium valproate, 25 (22.7%) benzodiazepines, 12 (10.9%) phenytoin, 9 (8.2%) lamotrigine, 8 (7.3%) Trileptal, and 7 (6.4%) gabapentin. SIGNIFICANCE: Our findings show that the incidences of newly diagnosed epileptic seizures and newly diagnosed epilepsy were high in the elderly population of La Réunion. These incidences were significantly higher in men than in women. These results may be attributable to the high incidence of cerebrovascular diseases and comorbidities in this population.
