Patterns, predictors, and outcomes of frailty trajectories in community-dwelling older adults: Results from the FREEDOM Cohort Study.

OBJECTIVES: To identify subgroups of people with distinct frailty trajectories, identify baseline characteristics associated with these trajectories, and determine their coincident clinical outcomes. DESIGN: This study examined the longitudinal database from the FREEDOM Cohort Study. SETTING AND PARTICIPANTS: All 497 participants of the FREEDOM (French Acronym for "FRagilitéEtEvaluation àDOMicile" / In English "Frailty and Evaluation at Home") cohort requested a comprehensive geriatric assessment. Community-dwelling subjects over 75 years, or over 65 years with at least two comorbidities were included. METHODS: Frailty was assessed using Fried's criteria, depression using the Geriatric Depression Scale (GDS) and cognitive function using the Mini Mental State Examination (MMSE) questionnaire. Frailty trajectories were modelled using k-means algorithms. Predictive factors were determined by multivariate logistic regression. Clinical outcomes included incident cognitive deficit, falls and hospitalization. RESULTS: The trajectory models allowed determine four frailty trajectories: "robust stable" (Trajectory A, 26.8%), "pre-frail worsening to frailty" (Trajectory B, 35.8%), "frail improving to less frailty" (Trajectory C, 23.3%), and "frail worsening to more frailty" (Trajectory D, 14.1%). Trajectory B was associated with age (OR 1.2 (95CI, 1.05 - 1.17)), potential cognitive deficit/dementia (OR 2.01 (95CI, 1.01- 4.05)) and depressive symptoms (OR 2.36 (95CI, 1.36 - 4.12)). Hypertension was distinguishing factor between" trajectory B vs. C and D. Depressive symptoms were two time more associated with D (OR 10.51) vs. C (OR 4.55). The incidence of clinical outcomes was significantly increased in poor frailty trajectories. CONCLUSIONS AND IMPLICATIONS: This study allowed to determine frailty trajectories among older subjects requested a comprehensive geriatric assessment. The more significant predictive factors associated with poor frailty trajectory were advanced in age, potential cognitive deficit/dementia, depressive symptoms and hypertension. This emphasizes the need for adequate measures to controlled hypertension, depressive symptoms and to maintain or improve cognition in older adults.

Risk factors of frailty and functional disability in community-dwelling older adults: a cross-sectional analysis of the FREEDOM-LNA cohort study.

BACKGROUND: Frailty is a geriatric syndrome associated with disability and negative health outcome. To determine the factors associated with frailty and functional disability in older participants living in community in France. We included 753 community-dwelling old participants with available frailty data at baseline. RESULTS: Overall, 31.9% were frail, 58.3% were prefrail, and 9.8% were robust. The SMAF (French acronym for Functional Autonomy Measurement System) score was significantly lower (mean ± standard deviation: -25.8 ± 11.2) in frail participants compared to prefrail (-14.3 ± 9.7) or robust participants (-8.1 ± 7.0); 82% of frail older participants had limitation in at least one ADL and 97.5% in at least one IADL compared to 54.2 and 76.8%, respectively of pre-frail and 29.7 and 47.3% of robust participants. Age, depression, impaired cognition and diabetes were significantly associated with higher odds of frailty. These variables were also strongly associated with functional disability. Female gender, polypharmacy, and smoking were additional variables significantly associated with degraded SMAF and/or ADL/IADL. CONCLUSIONS: This study showed that functional disability increased proportionally to frailty, and depression, cognitive decline and diabetes are modifiable risk factors significantly associated with frailty and functional disability.

Frailty and functional dependence in older population: lessons from the FREEDOM Limousin - Nouvelle Aquitaine Cohort Study.

BACKGROUND: Monitoring frailty indicators in elderly people is recommended to identify those who could benefit from disability prevention programs. To contribute to the understanding of the development of frailty in the elderly, we have created the FREEDOM-LNA cohort constituting an observational study of ageing in general population. Here, we described the characteristics of a cohort of elderly subjects who are followed for determination of frailty and loss of independence trajectories. RESULTS: The cohort was composed of 1085 subjects in advanced age (mean: 83.7 ± 6.0 years) and of women in majority (68.3%). Cardiovascular risk factors were present in 88.4% of subjects. Abnormal musculoskeletal signs were reported in 44.0% and neurologic signs in 31.9%. There were 44.8% of subjects at risk of malnutrition (MNA <24) and 73.3% (668/911) at risk of mobility-related disability (SPPB ≤9); 39% (384/973) of subjects had impaired cognitive function (MMSE< 24, adjusted on education) and 49.0% (397/810) had signs of depression (GDS >9); 31.8% (240/753) were frail and 58.3% were pre-frail. Most subjects had at least one disability in ADL (66.9%) and IADL (85.1%). The SMAF indicated a loss of independence in 59.6%. Overall, 59.9% of subjects could not stay at home without at least some help. Consequently, a medical consultation was proposed in 68.2 and 42.1% social supports. CONCLUSIONS: A large part of this cohort was frail or pre-frail and presented signs of loss of independence, which may be explained by multiple factors including impaired health status, poor physical performance, cognition, isolation, depression, or nutrition. This cohort will help to determine factors that adversely influence the trajectory of physical frailty over time.

Prevalence of tachyphagia at lunch and associated factors in a population of workers.

PURPOSE: Obesity is a public health problem worldwide. The eating habits of French workers need to be clarified. In particular, tachyphagia (meal lasting < 15 min) promotes weight gain. The present study aimed to investigate the presence of tachyphagia at lunchtime, the factors associated with tachyphagia, and the relationship between tachyphagia and obesity among workers. METHODS: This cross-sectional study was conducted between January and May 2016 in five departments of occupational medicine. An anonymous self-administered questionnaire was used to gather general declarative data, such as weight and height (to calculate body mass index [BMI]) and information about lunchtime habits, including the time spent eating. RESULTS: A total of 415 workers with a mean age of 41.1 ± 12.6 years were included. The mean BMI was 23.8 ± 4.6 kg/m2, and the prevalence of obesity was 15.9%. Tachyphagia occurred in 20.3% of the cases and was more frequent in younger workers. Multivariate analysis revealed that skipping meals, eating standing up, and eating fast food were positively associated with tachyphagia (p = 0.015, p = 0.028, and p = 0.027, respectively). Older age and eating with colleagues/friends were negatively associated with tachyphagia (p = 0.003 and p < 0.0001, respectively). No significant association was observed between tachyphagia and obesity. CONCLUSION: Our study provides important information about the lunchtime habits of workers. Maintaining commensality is crucial, particularly in young workers. Companies should play a role in organising their employees' lunch breaks. Level III Evidence obtained from well-designed cohort or case-control analytic studies.

Assessment of workplace environmental contamination and occupational exposure to cisplatin and doxorubicin aerosols during electrostatic pressurized intraperitoneal aerosol chemotherapy.

BACKGROUND: Electrostatic precipitation pressurized intraperitoneal aerosol chemotherapy (ePIPAC) is a novel approach for intraperitoneal drug delivery. As ePIPAC using cisplatin and doxorubicin is performed in an operating room, the challenge is to safely deliver the chemotherapeutic aerosol intraperitoneally while preventing exposure to healthcare workers. The objective of this study was to describe cisplatin and doxorubicin workplace environmental contamination and healthcare worker exposure during ePIPAC. METHODS: Antineoplastic drugs concentrations of cisplatin and doxorubicin were measured in wipe samples from the operating room, and urine samples were collected from healthcare workers. The air samples were collected in order to detect Cisplatin contamination. Cisplatin was analysed by inductively coupled plasma-mass spectrometry and doxorubicin by ultra-high-performance liquid chromatography coupled with tandem mass spectrometry. RESULTS: No trace of cisplatin was found in the air. Cisplatin and doxorubicin were detected on the operating room floor, surfaces, devices and personal protective equipment even after a cleaning protocol. No traces of cisplatin or doxorubicin were found in the urine samples. CONCLUSION: In this study, no internal contamination was found in the ePIPAC surgical team even after implementing two successive ePIPAC procedures. These results showed the effectiveness of the individual and collective protective measures applied. However, the cleaning procedure during ePIPAC should be respected to limit environmental exposure to chemotherapy to cisplatin and doxorubicin during ePIPAC.

Impact of knowledge, attitudes, and sociocultural factors on school enrollment of children with epilepsy in Gabon.

PURPOSE: Perceptions, beliefs and culture influence attitude towards epilepsy in sub-Saharan Africa. Misconceptions on epilepsy contribute to the persistence of negative attitudes in children with epilepsy particularly on their school enrollment. The aim of the study was to assess knowledge, attitudes, and sociocultural factors affecting schooling of children with epilepsy in Gabon. METHODS: Teachers and health workers from two urban and four rural localities of Gabon were assessed using a self-administered questionnaire. RESULTS: Overall 1310 subjects filled the survey questionnaire, including 813 teachers and 497 health workers. Knowledge on risk factors and suggestive signs of childhood epilepsy were globally poor. Misconceptions on etiology of epilepsy were significant with contagiousness (27.5%) and demonic possession (16.0%) representing the major prevalent idea about the origin of epilepsy in children. Attitudes of teachers and health workers towards schooling of children with epilepsy were positive (85.0%). However, more than half recommended enrollment of these children in specialized school programs. In multivariate analysis, education level (OR = 1.40; 95% confidence interval 1.01-1.81) and marital status (OR = 1.62; 95% confidence interval 1.18-2.22) were sociocultural factors likely to affect chances of school enrollment of children with epilepsy. CONCLUSION: Understanding the influence of socio-cultural factors surrounding school enrollment of children with epilepsy could enhance public awareness campaigns about epilepsy and to improve school integration of these children.

Updated evidence of the association between toxocariasis and epilepsy: Systematic review and meta-analysis.

OBJECTIVE: To gain further insight on the association between human toxocariasis and epilepsy in light of the new evidence in the last years. METHODS: A systematic review was conducted without date and language restriction in the following electronic databases: MEDLINE (PubMed), Ingenta Connect, Science Direct (Elsevier), RefDoc, Scopus, HighWire, Scielo and the database of the Institute of Neuroepidemiology and Tropical Neurology of the Limoges University (IENT). Two investigators independently conducted the search up to November 2017. A pooled odds ratio (OR) was estimated using a random effects model. Meta-regression was conducted to investigate potential sources of heterogeneity. RESULTS: Database search produced 204 publications. Eleven case-control studies were included that were carried out in 13 countries worldwide. A total number of 4740 subjects were considered (2159 people with epilepsy and 2581 people without epilepsy). The overall pooled OR was 1.69 (95% CI 1.42-2.01) for the association between epilepsy and Toxocara spp. seropositivity. A positive association was constantly reported in the restricted analysis (WB as confirmatory or diagnostic test, younger population, and population-based studies). Meta-regression showed no statistically significant association between covariates and outcome. CONCLUSION: The updated meta-analysis provides epidemiological evidence of a positive association between Toxocara seropositivity and epilepsy. New surveys supported the association, mainly population-based studies. On this basis, health strategies to reduce the impact of Toxocara spp are strongly advised. Further research should be performed to understand the physiopathological mechanisms of toxocara-associated epileptogenesis.

Urine cytology screening of French workers exposed to occupational urinary tract carcinogens: a prospective cohort study over a 20-year period.

OBJECTIVES: To demonstrate that urine cytology screening can provide relevant epidemiological data for earlier detection of urothelial cancer caused by occupational exposure. DESIGN: Prospective cohort study. SETTING: Industries using urothelial carcinogens in France. Urine samples were collected on site, after a work week and were analysed at the University Hospital of Clermont-Ferrand, France. PARTICIPANTS: Participants were workers exposed to urothelial carcinogens. Women and current smokers at time of study recruitment were exclusion criteria. OUTCOMES: Urine cells atypia were ranged into three classes: negative/normal, atypical/suspicious/dysplasia or positive/malignant. RESULTS: We included 2020 workers over a period of 20 years from 1993 to 2013: 606 worked in rubber manufacturing, 692 from metal processing, 245 in chemical industry and 477 in roadwork and building industry. Workers had a mean exposure of 15.2±10.4 years before their first urine cytology screening. There was a mean of 3.4±4.3 urine cytology screenings per worker between 1993 and 2013. 6478 cytology were normal, 462 suspicious and 13 malignant. Suspicious and malignant cytology occurred in 4.8% of workers exposed for 1-10 years, 6.2% for 11-20 years of exposure, 7.6% for 21-30 years and 8.6% for >30 years (p<0.001). Using exposure for 1-10 years as reference, the adjusted OR of receiving a suspicious or malignant diagnosis increased with duration of exposure: OR=1.50 (95% CI 1.10 to 2.05, p=0.01) for 21-30 years and OR=1.78 (95% CI 1.23 to 2.56, p=0.002) for >30 years of exposure. Using metal processing as reference, the risk of pathological urine cytology results increased for rubber manufacturing (OR=1.32, 95% CI 1.05 to 1.65, p=0.02), with a trend for roadwork and building industry (OR=1.39, 95% CI 0.98 to 1.97, p=0.07) and for chemical industry (OR=1.34, 95% CI 0.94 to 1.93, p=0.11). CONCLUSIONS: Urine cytology is a useful tool in occupational medicine. We promote new guidelines with an early screening of urothelial cancer by cytology, starting with beginning of exposure.

Biomonitoring of 29 trace elements in whole blood from inhabitants of Cotonou (Benin) by ICP-MS.

This study aimed to investigate the blood concentration of 29 trace elements, metals or metalloids, in a healthy population of Cotonou not directly exposed to metals in order to propose reference values. Blood samples from 70 blood donors were collected in K2 EDTA tubes for trace elements during September 2015 and a questionnaire was used to assess lifestyle exposure. Blood metal concentrations were determined by inductively coupled plasma mass spectrometry (ICP-MS) equipped with a quadrupole-based reaction cell. Among the selected blood donors 51.4% were aged from 18 to 36 years and 49.6% from 37 to 65 years. Among the 29 elements analyzed As, Pb, Mn, Pd, Sb, Co, Se, Sr showed blood concentrations higher than the reference values found in the literature for non-exposed healthy European populations and their geometric means were respectively 5.81; 47.39; 19.71; 1.91; 7.50; 0.66; 163.01; 30.53µg/L. This study provides the first reference value (5th-95th percentiles) for each element in Cotonou, which enables us to carry out further investigations on environmental and occupational exposure.

A French crop-exposure matrix for use in epidemiological studies on pesticides: PESTIMAT.

Pesticide exposure assessment is a key methodological issue for epidemiological studies. The history of pesticide has proven difficult to obtain from individuals' report because of the wide range of active ingredients (AIs). We developed a crop-exposure matrix, which intends to reconstitute parameters of pesticide exposure in France since 1950. PESTIMAT is composed of tables crossing crops and AIs by year and providing the following metrics: (1) probability (proportion of farmers having used the AIs); (2) frequency (number of treatment days); and (3) intensity (application rate of the AIs in kg/ha). Metrics were obtained by the combination of six sources: (i) registration information from the Agriculture Ministry; (ii) information from agricultural bodies on products marketed; (iii) agricultural recommendations by the Plant Health Protection body; (iv) treatment calendars provided by farmers; (v) data from associations of farmers; and (vi) data from the industry. To date, 529 AIs usable between 1950 and 2010 are included in PESTIMAT: 160 fungicides; 160 herbicides; and 209 insecticides. When combined with duration and determinants of intensity, the metrics in PESTIMAT will make it possible to calculate exposure scores and to search for dose-effect relationships, an important criterion for causality judgment in epidemiology.

How to reduce the treatment gap for people with epilepsy in resource-limited settings by innovative galenic formulations: A review of the current situation, overview of potential techniques, interests and limits.

Epilepsy is a chronic neurological disease affecting more than 69 million people worldwide, nearly 90% of them in low and middle-income countries (LMICs). In those countries, only four major antiepileptic drugs are commonly used: phenobarbital, carbamazepine, sodium valproate and phenytoin. There are also problems with the accessibility, availability and quality of drugs. The main objective was to review the literature concerning "long" sustained-release formulations of AEDs that have the potential to reduce the number of administrations and help overcome problems of compliance, accessibility and the treatment gap. The main endpoint was a releasing of the active ingredient over more than 24h. We also assessed the feasibility and acceptability in resource-limited settings. Two drugs were found in unconventional release formulations: carbamazepine and sodium valproate; but they were not "long" sustained release because they required administration once a day. Several techniques were available, including: esterification, transdermal devices, liposomes and polymeric devices preformed or formed in situ. In situ methods for the preparation of injectable biodegradable microparticles or implants for controlled delivery seemed best suited to the objective. Furthermore, they appear to fulfil the requirements of feasibility and cost. Sodium valproate appeared as well to be a relevant candidate for a "long" sustained release formulation that would improve access to medicines for people with epilepsy in resource-limited settings. .

Impact of epilepsy on children and parents in Gabon.

Children with epilepsy and their parents face many social and psychological difficulties that remain insufficiently studied in sub-Saharan Africa. The aim here was to assess the quality of life of children with epilepsy and their parents. A community-based cross-sectional survey was conducted in two urban areas and four rural areas of Gabon. Children were screened through key informants, medical sources, and a door-to-door survey. They were clinically selected based on their medical history and a clinical exam conducted by the investigating physician. Electroencephalography had not been carried out because of a lack of material and financial resources. The quality of life of children and their parents was assessed by a structured interview of parents using a questionnaire. Of 317 suspected cases on screening, 83 children with epilepsy were identified. Their mean age was 11.9±4.4years. Twelve percent of the children had neurosensory abnormalities on clinical exam. Sixty-three percent of them attended school; factors associated with schooling were higher score on the sociability subscale, specialized medical advice, and antiepileptic drug treatment. Sociability difficulties, anxiety, cognitive impairment, and behavioral disorders were suspected in 39.8%, 45.8%, 49.4%, and 42.2% of children, respectively. A total of 48.2% of parents expressed a poor quality of life related to their children's illness. A higher score on the cognition subscale, urban residence, specialized medical advice, and a stable income in the household were predictive of poor parental quality of life. Epilepsy influences many aspects of a child's life and the life of the child's parents. Care should incorporate a cognitive assessment of the child and emphasize information for patients and their relatives.

Epidemiology, causes, and treatment of epilepsy in sub-Saharan Africa.

SUMMARY: Epilepsy is a common neurological disease in tropical countries, particularly in sub-Saharan Africa. Previous work on epilepsy in sub-Saharan Africa has shown that many cases are severe, partly a result of some specific causes, that it carries a stigma, and that it is not adequately treated in many cases. Many studies on the epidemiology, aetiology, and management of epilepsy in sub-Saharan Africa have been reported in the past 10 years. The prevalence estimated from door-to-door studies is almost double that in Asia, Europe, and North America. The most commonly implicated risk factors are birth trauma, CNS infections, and traumatic brain injury. About 60% of patients with epilepsy receive no antiepileptic treatment, largely for economic and social reasons. Further epidemiological studies should be a priority to improve understanding of possible risk factors and thereby the prevention of epilepsy in Africa, and action should be taken to improve access to treatment.

Searching for a link between the L-BMAA neurotoxin and amyotrophic lateral sclerosis: a study protocol of the French BMAALS programme.

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is the most common motor neurone disease. It occurs in two forms: (1) familial cases, for which several genes have been identified and (2) sporadic cases, for which various hypotheses have been formulated. Notably, the ß-N-methylamino-L-alanine (L-BMAA) toxin has been postulated to be involved in the occurrence of sporadic ALS. The objective of the French BMAALS programme is to study the putative link between L-BMAA and ALS. METHODS AND ANALYSIS: The programme covers the period from 1 January 2003 to 31 December 2011. Using multiple sources of ascertainment, all the incident ALS cases diagnosed during this period in the area under study (10 counties spread over three French regions) were collected. First, the standardised incidence ratio will be calculated for each municipality under concern. Then, by applying spatial clustering techniques, overincidence and underincidence zones of ALS will be sought. A case-control study, in the subpopulation living in the identified areas, will gather information about patients' occupations, leisure activities and lifestyle habits in order to assess potential risk factors to which they are or have been exposed. Specimens of drinking water, food and biological material (brain tissue) will be examined to assess the presence of L-BMAA in the environment and tissues of ALS cases and controls. ETHICS AND DISSEMINATION: The study has been reviewed and approved by the French ethical committee of the CPP SOOM IV (Comité de Protection des Personnes Sud-Ouest & Outre-Mer IV). The results will be published in peer-reviewed journals and presented at national and international conferences.

French version of the Rating Scale for aggressive behaviour in the Elderly (F-RAGE): psychometric properties and diagnostic accuracy / Versão francesa da Escala de Avaliação do Comportamento Agressivo em Idosos: propriedades psicométricas e utilidade diagnóstica

Aggressive behaviour is the most disturbing and distressing behaviour displayed by elderly people. The prevalence of aggressive behaviour is around 50% among psychogeriatric patients. OBJECTIVE: This study sought to analyze the psychometric properties and diagnostic accuracy of the French version of the Rating Scale for Aggressive Behaviour in the Elderly (F-RAGE). METHODS: The F-RAGE was administered to 79 patients hospitalized in a geriatric psychiatry department. A psychiatrist, who was blind to the subjects' RAGE scores, performed the diagnosis for aggressivity based on global clinical impression. The F-RAGE and MMSE were applied by a trained researcher blind to subjects' clinical diagnoses while the Cohen-Mans Agitation Inventory and Neuropsychiatric Inventory were administered by medical and nursing staff. Internal consistency, reliability, cut-off points, sensitivity and specificity for F-RAGE were estimated. RESULTS: F-RAGE showed satisfactory validity and reliability measurements. Regarding reliability, Cronbach's ? coefficient was satisfactory with a value of 0.758. For diagnostic accuracy, a cut-off point of 8 points (sensitivity=74.19%; specificity=97.98%) and area under curve of 0.960 were estimated to distinguish between aggressive patients and control subjects. DISCUSSION: F-RAGE showed acceptable psychometric properties, supported by evidence of validity and reliability for its use in the diagnosis of aggressive behaviour in elderly.

O comportamento agressivo é o comportamento mais perturbador e angustiante que possa ser apresentado pelos idosos. A prevalência de comportamento agressivo é cerca de 50% entre os pacientes psicogeriátricos. OBJETIVO: Analisar as propriedades psicométricas e acurácia diagnóstica da versão francesa da Escala de Avaliação do Comportamento Agressivo em Idosos (F-RAGE). MÉTODOS: A F-RAGE foi administrada a 79 pacientes internados no departamento de psiquiatria geriátrica. Um psiquiatra que era cego às pontuações F-RAGE dos sujeitos realizou o diagnóstico de DSM-IV com base na impressão clínica global. O F-RAGE e MMSE foram realizados por um pesquisador treinado cego ao diagnóstico clínico dos sujeitos e o Inventário de agitação de Cohen-Mans e o Inventário Neuropsiquiátrico pela equipe médica e de enfermagem. Consistência interna, pontos de corte, sensibilidade e especificidade para F-RAGE foram estimados. RESULTADOS: F-RAGE mostrou validade satisfatória e medidas de confiabilidade. Em relação à confiabilidade, coeficiente ? de Cronbach foi satisfatória com um valor de 0,758. Para maior precisão de diagnóstico, um ponto de corte de 8 pontos (sensibilidade=74,2%, especificidade=98,0%) e área sob a curva de 0,960 foram estimados para distinguir entre os pacientes agressivos e controles.DISCUSSÃO: F-RAGE mostrou propriedades psicométricas aceitáveis, apoiados por evidências de validade e confiabilidade para sua utilização no diagnóstico do comportamento agressivo em idosos.

Epilepsy in Cambodia-treatment aspects and policy implications: a population-based representative survey.

INTRODUCTION: We tested two treatment strategies to determine: treatment (a) prognosis (seizure frequency, mortality, suicide, and complications), (b) safety and adherence of treatment, (c) self-reported satisfaction with treatment and self-reported productivity, and policy aspects (a) number of required tablets for universal treatment (NRT), (b) cost of management, (c) manpower-gap and requirements for scaling-up of epilepsy care. METHODS: We performed a random-cluster survey (N = 16510) and identified 96 cases (≥1 year of age) in 24 villages. They were screened by using a validated instrument and diagnosed by the neurologists. International guidelines were used for defining and classifying epilepsy. All were given phenobarbital or valproate (cost-free) in two manners patient's door-steps (March 2009-March 2010, primary-treatment-period, PTP) and treatment through health-centers (March 2010-June 2011, treatment-continuation-period, TCP). The emphasis was to start on a minimum dosage and regime, without any polytherapy, according to the age of the recipients. No titration was done. Seizure-frequency was monthly and self-reported. RESULTS: The number of seizures reduced from 12.6 (pre-treatment) to 1.2 (end of PTP), following which there was an increase to 3.4 (end of TCP). Between start of PTP and end of TCP, >60.0% became and remained seizure-free. During TCP, ∼26.0% went to health centers to collect their treatment. Complications reduced from 12.5% to 4.2% between start and end of PTP and increased to 17.2% between start and end of TCP. Adverse events reduced from 46.8% to 16.6% between start and end of PTP. Nearly 33 million phenobarbital 100 mg tablets are needed in Cambodia. CONCLUSIONS: Epilepsy responded sufficiently well to the conventional treatment, even when taken at a minimal dosage and a simple daily regimen, without any polytherapy. This is yet another confirmation that it is possible to substantially reduce direct burden of epilepsy through means that are currently available to us.

Comprehensive evaluation of the psychosocial parameters of epilepsy: a representative population-based study in Prey Veng (Cambodia).

PURPOSE: We conducted a population-based study of epilepsy in Prey Veng (Cambodia) to explore self-esteem, fear, discrimination, knowledge-attitude-practice (KAP), social-support, stigma, coping strategies, seizure-provoking factors, and patient-derived factors associated with quality of life (QOL). METHODS: The results are based on a cohort of 96 cases and matched controls (n = 192), randomly selected from the same source population. Various questionnaires were developed and validated for internal consistency (by split-half, Spearman-Brown prophecy, Kuder-Richardson 20), content clarity and soundness. Summary, descriptive statistics, classical tests of hypothesis were conducted. Uncorrected chi-square was used. Group comparison was done to determine statistically significant factors, for each domain, by conducting logistic regression; 95% confidence interval (CI) with 5% (two-sided) statistical significance was used. KEY FINDINGS: All questionnaires had high internal consistency. Stress was relevant in 14.0% cases, concealment in 6.2%, denial in 8.3%, negative feelings in public in 3.0%. Mean self-esteem was 7.5, range 0-8, related to seizure frequency. Mean discrimination was least during social interactions. Coping strategies were positive (e.g. look for treatment). Postictal headache, anger, no nearby health facility, etc. were associated with QOL. SIGNIFICANCE: The reliability of our questionnaires was high. A positive social environment was noted with many infrequent social and personal prejudices. Not all populations should (by default) be considered as stigmatized or equipped with poor KAP. We addressed themes that have been incompletely evaluated, and our approach could therefore become a model for other projects.

Epilepsy in Asia: a Cambodian experience.

Epilepsy is particularly challenging for resource-poor countries and in turn for Asia which is likely to have greater challenges in terms of treatment cost and deficit, premature mortality, health transitions, population and poverty size, etc. Here we present an example of working in one of the resource-poor 'least-talked-about' populations to demonstrate that finding financial means and achieving cross-country cooperation over a long period of time is possible even in countries with currently limited resources. Conducting such cooperation could be a model for other initiatives. Scientific, capacity-building, and political tools should be employed to generate local representative data and influence government policies. These measures can be of immediate benefit for patients in these countries.

Epidemiology of epilepsy in rural Benin: prevalence, incidence, mortality, and follow-up.

PURPOSE: Epilepsy is a major clinical and social issue in Africa. This study was conducted to estimate the prevalence, incidence, mortality, and therapeutic outcome in rural Djidja in Benin. METHODS: This was a two-phase study with a cross-sectional phase and 18 months of follow-up. In the first phase, information was obtained using door-to-door surveys, reports from key informants, and medical sources. People were interviewed using a validated screening questionnaire for epilepsy in tropical regions. The diagnosis of epilepsy was confirmed by a neurologist. We used a capture-recapture method to estimate the number of people with epilepsy (PWE). PWE were followed every month for 18 months after the cross-sectional survey. We asked the health services, the general population, and village leaders in the study area to identify suspected cases of epilepsy occurring during the follow-up. New cases were updated every month after confirmation. Antiepileptic drugs were prescribed to PWE. KEY FINDINGS: We surveyed 11,668 subjects (male-to-female ratio 0.9) and identified 123 PWE, yielding a prevalence of 10.5 per 1,000 (95% confidence interval (CI) 8.8-12.6/1,000). Combining the three sources, we found 148 PWE and a prevalence of 12.7 per 1,000 (95% CI 10.7-14.9/1,000). After application of the capture-recapture method, the prevalence was estimated to be as high as 38.4 per 1,000 (95% CI 34.9-41.9/1,000). The cumulative incidence was 104.2 per 100,000 and the mean annual incidence was 69.4 per 100,000. The mean annual mortality was 20.8 per 1,000. After treatment, 45% of PWE had total seizure remission and 35% had a decrease in the number of seizures. SIGNIFICANCE: This study shows that door-to-door survey findings could be improved by using information from other sources. The follow-up suggests that epilepsy could be controlled. Continuous drug delivery and regular follow-up are key.

Population-based study of epilepsy in Cambodia associated factors, measures of impact, stigma, quality of life, knowledge-attitude-practice, and treatment gap.

PURPOSE: Identify epilepsy-associated factors and calculate measures of impact, stigma, quality of life (QOL), knowledge-attitude-practice (KAP) and treatment gap in Prey Veng, Cambodia. METHODS: This first Cambodian population-based case-control study had 96 epileptologist-confirmed epilepsy cases and 192 randomly selected matched healthy controls. Standard questionnaires, which have been used in similar settings, were used for collecting data on various parameters. Univariate and multivariate regression was done to determine odds ratios. Jacoby stigma, 31-item QOL, KAP etc were determined and so were the factors associated with them using STATA software. Treatment gap was measured using direct method. KEY FINDINGS: Multivariate analyses yielded family history of epilepsy, difficult or long delivery, other problems beside seizures (mainly mental retardation, hyperthermia), and eventful pregnancy of the subject's mother as factors associated with epilepsy. There was high frequency of seizure precipitants esp. those related to sleep. Population attributable risk (%) was: family history (15.0), eventful pregnancy of subject's mother (14.5), long/difficult birth (6.5), and other problem beside seizures (20.0). Mean stigma (1.9±1.1, on a scale of 3) was mainly related to treatment efficacy. Mean QOL (5.0±1.4 on a scale of 10) was mainly related to treatment regularity. Cause or risk factor could be determined in 56% of cases. Treatment gap was 65.8%. SIGNIFICANCE: Factors in pre- and perinatal period were found to be most crucial for epilepsy risk in Cambodia which inturn provides major prevention opportunities. A global action plan for treatment, stigma reduction and improvement of QOL should be set-up in this country.
