International cooperation and the challenge of internet accessibility in Caribbean territories: example of a collaborative platform between the University Hospital of Martinique and Ramón González Coro Hospital in Cuba, through the French PRPH-3 program.

BACKGROUND: Martinique shares with the other Caribbean countries specific public health issues, particularly in the diagnostic and therapeutic management of cancer patients. Mutualization of human and material resources by promoting cooperation is the most appropriate response to the challenges of the health systems of the Caribbean territories. Through the French PRPH-3 program, we propose to set up a collaborative digital platform adapted to the specificities of the Caribbean to strengthen professional links and skills in oncofertility and oncosexology and reduce inequalities in access to reproductive and sexual health care for cancer patients. METHODS: Within the context of this program, we have developed of an open-source platform based on a Learning Content Management System (LCMS), with an operating system developed by UNFM for low speed internet. LO libraries have been created and interaction between trainers and learners were done in asynchronous mode. This training management platform is based on: a TCC learning system (Training, Coaching, Communities); a web-hosting with pedagogical engineering appropriate to low bandwidth; a reporting system and a responsibility for processing. RESULTS: We have carried out a flexible, multilingual and accessible digital learning strategy functionality called e-MCPPO according to low-speed internet ecosystem. In close connection with the e-learning strategy we conceived (i) a multidisciplinary team; (ii) an appropriate training program for expert health professionals and (iii) a responsive design. DISCUSSION AND CONCLUSION: This low-speed web-based infrastructure allows communities of experts to cooperate in creating, validating, publishing and managing academic learning content. The self-learning modules provide the digital layer for each learner to extend their skills. Learners, as well as trainers, would gradually take ownership of this platform and encourage its promotion. Innovation in this context is both technological (low-speed Internet broadcasting, free interactive software) and organizational (moderating educational resources). This collaborative digital platform is unique in its form and content. This challenge could contribute to the digital transformation of the Caribbean ecosystem for capacity building in this specifics topics.

Collaborative digital platform France - Cuba: oncorehabilitation in reproductive and sexual health.

BACKGROUND: In the French West-Indies, few studies have been performed on fertility and sexual problems in cancer survivors, which are frequent and recurring issues reported by surveys on unmet needs. Additionally, mutualizing human and material resources and promoting cooperation through a collaborative platform are the most appropriate response to complex health pathways in the Caribbean territories. Implementation of such a collaborative platform will help to launch a strategic Caribbean partnership to transfer theoretical and technical skills and care standards in oncofertility and oncosexuality. METHODS: We propose to set up a collaborative digital platform to strengthen, from the French expertise, Cuban health professionals' knowledge, know-how, and skills in oncofertility and oncosexuality. The project will be coordinated by a coordinating, scientific, and supervisory committee, and the main activities will include: 1. Theoretical training in e-learning adapted to low-speed Internet. 2. Practical training in fertility preservation and sexual rehabilitation. 3. Digital multidisciplinary consultation meetings for medical decisions to be taken for complex clinical cases. The platform will benefit from a recurrent evaluation, by the two cancer registries of Martinique and Cuba, with the following performance indicators: number of Cuban professionals trained, number of professionals sensitized, hourly volumes (or number of training courses provided), satisfaction of trained professionals, number of e-RCPs carried out online and number of missionaries supported. These indicators will be set up and analyzed by the registers. This project meets the Cuban and French health policies (cancer plans and national sexual health strategies) and will be implemented in liaison with the Health Agencies of both countries and the Embassy of France in Cuba. DISCUSSION: This project aims to provide support through bilateral exchanges to improve reproductive and sexual health in Cuba's cancer patients. This collaboration will be based on a long-lasting French expertise and a solid Cuban health system. Consequently, this collaborative digital platform will contribute to data collection for cancer surveillance, and the two participating countries will ultimately be identified in the Caribbean as having centers of competence and excellence in oncofertility and oncosexuality with care standards.

[The use of psychoactive substances among street teenagers in Ouagadougou]. / Usage de substances psychoactives chez les adolescents des rues à Ouagadougou.

Objectives: To study the determinants of psychoactive substance use among street teenagers living in Ouagadougou.Methods: Qualitative and quantitative cross-sectional study with street teenagers living on the Zogona campus in Ouagadougou, in September 2012. A focus group was then formed with eight members of the group.Results: The median age was 16 years (range: 12 to 20 years). The various psychotropic agents were tobacco, alcohol, gasoline, glue sniffing and cannabis. Seventeen of the 31 teenagers had already been admitted to a rehabilitation centre and none of them attended school at the time of data collection. However, 12 street teenagers had previously attended school. The main reasons for the presence of these teenagers in the street were "poverty in the family", "death of the parents", "Koranic school". The main reasons reported by the teenagers for substance use were "to give oneself courage", "to relieve hunger", "to be like the others", "to be accepted by the group", "to protect oneself from the cold". The main determinants of substance abuse were social exclusion, group membership, and group identification.Conclusion: Psychoactive substance use is an integral part of the life of street teenagers and is a major obstacle to social integration.

Calcium role in human carcinogenesis: a comprehensive analysis and critical review of literature.

The central role played by calcium ion in biological systems has generated an interest for its potential implication in human malignancies. Thus, lines of research, on possible association of calcium metabolism regulation with tumorigenesis, implying disruptions and/or alterations of known molecular pathways, have been extensively researched in the recent decades. This paper is a critical synthesis of these findings, based on a functional approach of the calcium signaling toolkit. It provides strong support that this ubiquitous divalent cation is involved in cancer initiation, promotion, and progression. Different pathways have been outlined, involving equally different molecular and cellular structures. However, if the association between calcium and cancer can be described as constant, it is not always linear. We have identified several influencing factors among which the most relevant are (i) the changes in local or tissular concentrations of free calcium and (ii) the histological and physiological types of tissue involved. Such versatility at the molecular level may probably account for the conflicting findings reported by the epidemiological literature on calcium dietary intake and the risk to develop certain cancers such as the prostatic or mammary neoplasms. However, it also fuels the hypothesis that behind each cancer, a specific calcium pathway can be evidenced. Identifying such molecular interactions is probably a promising approach for further understanding and treatment options for the disease.
