Adhésion thérapeutique aux traitements oncologiques oraux et prise en charge interdisciplinaire [Therapeutic adherence to oral cancer therapy and interdisciplinary management].

Medication adherence is a well-known risk factor in internal medicine. However in oncology this dimension is emerging due to the increasing number of oral formulations. First results in the oral oncology literature suggest that patients' ability to cope with medical prescription decreases with time. This might preclude patients from reaching clinical outcomes. Factors impacting on medication adherence to oral oncology treatments have not been yet extensively described neither strategies to address them and support patient's needs. Oncologists and pharmacists in our University outpatient settings performed a pilot study which aimed at measuring and facilitating adherence to oral oncology treatments and at understanding determinants of patient's adherence. The ultimate purpose of such a patient-centered and interdisciplinary collaboration would be to promote patient self-management and complement the standard medical follow-up.

Body mass index, cigarette smoking, and alcohol consumption and cancers of the oral cavity, pharynx, and larynx: modeling odds ratios in pooled case-control data.

Odds ratios for head and neck cancer increase with greater cigarette and alcohol use and lower body mass index (BMI; weight (kg)/height(2) (m(2))). Using data from the International Head and Neck Cancer Epidemiology Consortium, the authors conducted a formal analysis of BMI as a modifier of smoking- and alcohol-related effects. Analysis of never and current smokers included 6,333 cases, while analysis of never drinkers and consumers of < or =10 drinks/day included 8,452 cases. There were 8,000 or more controls, depending on the analysis. Odds ratios for all sites increased with lower BMI, greater smoking, and greater drinking. In polytomous regression, odds ratios for BMI (P = 0.65), smoking (P = 0.52), and drinking (P = 0.73) were homogeneous for oral cavity and pharyngeal cancers. Odds ratios for BMI and drinking were greater for oral cavity/pharyngeal cancer (P < 0.01), while smoking odds ratios were greater for laryngeal cancer (P < 0.01). Lower BMI enhanced smoking- and drinking-related odds ratios for oral cavity/pharyngeal cancer (P < 0.01), while BMI did not modify smoking and drinking odds ratios for laryngeal cancer. The increased odds ratios for all sites with low BMI may suggest related carcinogenic mechanisms; however, BMI modification of smoking and drinking odds ratios for cancer of the oral cavity/pharynx but not larynx cancer suggests additional factors specific to oral cavity/pharynx cancer.

Oral cancer treatments and adherence: medication event monitoring system assessment for capecitabine

Background: Oncological treatments are traditionally administered via intravenous injection by qualified personnel. Oral formulas which are developing rapidly are preferred by patients and facilitate administration however they may increase non-adherence. In this study 4 common oral chemotherapeutics are given to 50 patients, who are still in the process of inclusion, divided into 4 groups. The aim is to evaluate adherence and offer these patients interdisciplinary support with the joint help of doctors and pharmacists. We present here the results for capecitabine. Materials and Methods: The final goal is to evaluate adhesion in 50 patients split into 4 groups according to oral treatments (letrozole/exemestane, imatinib/sunitinib, capecitabine and temozolomide) using persistence and quality of execution as parameters. These parameters are evaluated using a medication event monitoring system (MEMS®) in addition to routine oncological visits and semi-structured interviews. Patients were monitored for the entire duration of treatment up to a maximum of 1 year. Patient satisfaction was assessed at the end of the monitoring period using a standardized questionary. Results: Capecitabine group included 2 women and 8 men with a median age of 55 years (range: 36−77 years) monitored for an average duration of 100 days (range: 5-210 days). Persistence was 98% and quality of execution 95%. 5 patients underwent cyclic treatment (2 out of 3 weeks) and 5 patients continuous treatment. Toxicities higher than grade 1 were grade 2−3 hand-foot syndrome in 1 patient and grade 3 acute coronary syndrome in 1 patient both without impact on adherence. Patients were satisfied with the interviews undergone during the study (57% useful, 28% very useful, 15% useless) and successfully integrated the MEMS® in their daily lives (57% very easily, 43% easily) according to the results obtained by questionary at the end of the monitoring period. Conclusion: Persistence and quality of execution observed in our Capecitabine group of patients were excellent and better than expected compared to previously published studies. The interdisciplinary approach allowed us to better identify and help patients with toxicities to maintain adherence. Overall patients were satisfied with the global interdisciplinary follow-up. With longer follow up better evaluation of our method and its impact will be possible. Interpretation of the results of patients in the other groups of this ongoing trial will provide us information for a more detailed analysis.

Protocolo técnico para la evaluación acústica de las áreas de distribución y abundancia de recursos pelágicos en el mar peruano. Versión 2009

En este Protocolo se describe la metodología utilizada durante el periodo1996 a 2009. Para ello, se ha estratificado el mar frente al Perú en Áreas Isoparalitorales (AIP) formadas por la proyección imaginaria de la línea de costa cada 10 mn, las que son cortadas cada 30 minutos por los paralelos de latitud hasta una distancia de 300 millas náuticas desde la línea de costa (Gutiérrez y Peraltilla 1999).

Protocolo para la evaluación de concha de abanico Argopecten purpuratus (LAMARCK, 1819)

La Unidad de Investigaciones de Invertebrados Marinos en conjunto con las sedes descentralizadas del Instituto del Mar del Perú, IMARPE, con fines de establecer y estandarizar los procedimientos para la estimación de la población y biomasa de concha de abanico (Argopecten purpuratus) en áreas silvestres, elaboró este protocolo que describe los pasos a seguir desde la planificación en escritorio, la ejecución a bordo de embarcaciones, pasando por los cálculos estadísticos, hasta la elaboración del informe ejecutivo. La estimación de la población y biomasa de concha de abanico, en áreas silvestres se realiza dentro del contexto de evaluación poblacional, que involucra este primer aspecto e incorpora: estructura poblacional por tallas y madurez gonadal, relaciones biométricas y biológicas, y las condiciones ambientales predominantes del ambiente marino. La correcta aplicación de estos procedimientos conducirá a la obtención de información confiable.

Adhésion thérapeutique en oncologie : persistance, qualité d'exécution et satisfaction des patients sous traitement oral et MEMS®

Introduction: en oncologie apparaissent sur le marché depuis quelques années de nouveaux traitements en formulation orale facilitant l'administration et améliorant la qualité de vie du patient mais augmentant le risque de non adhésion et d'erreurs de posologie. L'observation par MEMS® (Medication Event Monitoring System) permet le suivi et l'encadrement du traitement oral et par le biais d'entretiens semi structurés menés par le pharmacien, ouvre la discussion sur les problèmes révélés par cette prise en charge. Méthode: étude non randomisée prospective uni centrique regroupant 50 patients inclus dans 3 groupes de traitements oncologiques oraux courants (capecitabine, letrozole/exemestane, imatinib/sunitinib) bénéficiant d'un suivi oncologique classique et équipés d'un MEMS® pour un an maximum. La persistance et la qualité d'exécution sont les deux paramètres mesurés grâce aux données récoltées électroniquement. Les entretiens sont dédiés à la prévention de la non adhésion et à la gestion des effets secondaires médicamenteux. La satisfaction est évaluée par un questionnaire à la fin du suivi. Résultats: à ce jour 38 patients ont été inclus dans l'étude. Les données complètes sont disponibles pour les 19 premiers patients dont 10 sous capecitabine et 9 sous letrozole/exemestane. Dans ce collectif l'âge médian est de 66 ans avec une majorité de femmes (11:8). La persistance à 10 jours est de 85% et la qualité d'exécution de 99%. Les toxicités observées supérieures à grade 1 sont 1 syndrome mains-pieds (G3) et 1 syndrome coronarien aigu (G3). Le questionnaire de fin de suivi relève une satisfaction de 85% des patients pour les entretiens proposés (57% utiles, 28% très utiles, 15% inutiles) et le succès quant à l'intégration du MEMS® dans leur quotidien (57% très facile, 43% facile). Conclusion: la persistance et la qualité d'exécution observées dans notre collectif sont excellentes. La satisfaction retrouvée auprès des patients reflète le besoin d'un soutien complémentaire face à la complexité de la maladie oncologique. La gestion pluridisciplinaire profite tant aux patients qu'au binôme médecin-pharmacien par l'amélioration de la communication globale entre les divers acteurs et par l'identification précoce des risques de non adhésion. La poursuite de cette étude et l'analyse des futures données permettra de mesurer le réel impact de notre intervention et de justifier le bénéfice pour des patients sous traitement similaire.

Oral pregabalin as an add-on treatment for status epilepticus.

Oral antiepileptic drugs (AEDs) represent possible add-on options in refractory status epilepticus (SE). In this setting, pregabalin (PGB) has not been reported before. Over the last 42 months, we identified 11 SE episodes (10 patients) treated with PGB in our hospital. Its use was prompted by the favorable pharmacokinetic profile, devoid of drug-drug interactions. The patients mostly had refractory, partial SE. Only two patients were managed in the intensive care unit (ICU). We found a definite electroclinical response in 5 of 11, already evident 24 h after PGB introduction, and a possible response (concomitantly with other AEDs) in 3 of 11 of the episodes; 3/11 did not respond. The treatment was well tolerated. Partial SE appeared to better respond than generalized convulsive SE. PGB appears to be an interesting option as add-on treatment in refractory partial SE.
