Children with intellectual disabilities’ perceptions of their participation in activities in everyday life – a pilot study : A minor field study conducted in Ethiopia

Background: Children with disabilities living in low and middle income countries��� perceptions of participation are not shown in research. These perceptions are important for providing appropriate interventions. Aim: To describe how children aged 8-12 with an intellectual disability living in Ethiopia perceive their situation regarding participation in activities in everyday life. Method: A descriptive design with a quantitative approach was used. The sample was gathered using consecutive sampling. Fifteen structured interviews were conducted, using “Picture my participation,” an instrument under development. Analyses were made using SPSS Statistics and Microsoft Excel. Results: The children perceived that they participated in activities in everyday life. There was a broad variation in the activities the children prioritized as most important. On a group level, they were very involved in these activities. The majority did not experience any barriers to perform these activities. Conclusions: The perceptions of the majority of the children were that they were involved in daily activities. They did not experience any barriers to participation. The results should be read with caution and generalization is not possible, due to the sample characteristics and that the instrument is under development.

Anomalies immunitaires chez les enfants exposés au VIH mais non infectés.

La thérapie antirétrovirale prévient la transmission mère-enfant du VIH dans plus de 98% des cas lorsqu’administrée pendant la grossesse, le travail et au nouveau-né. L’accessibilité à la thérapie antirétrovirale dans près de 70% des 1,5 millions cas de grossesses VIH+ dans le monde mène à la naissance de plus d’un million d’enfants exposés non infectés chaque année. Le nombre d’enfants exposés non infectés est à la hausse ainsi que les préoccupations concernant leur santé. En effet, plusieurs groupes ont signalé une augmentation de la morbidité et de la mortalité chez les enfants exposés non infectés. L’analyse des données rétrospectives de 705 enfants exposés non infectés de la cohorte mère-enfant du CMIS a révélé qu’à 2 mois d’âge, les enfants nés de mères ayant une charge virale supérieure à 1,000 copies d’ARN / ml avaient une fréquence de lymphocytes B significativement plus élevés par rapport aux enfants exposés non infectés nés de mères ayant une charge virale indétectable. L’objectif de cette étude est de caractériser ces anomalies. Les lymphocytes, provenant du sang de cordon ombilical et de sang veineux obtenu à 6 et 12 mois d’âge, ont été phénotypés par cytométrie en flux à l’aide des marqueurs CD3 / CD10 / CD14 / CD16 / CD19 / CD20 / CD21 / CD27 / IgM pour les lymphocytes B et CD4 / CD8 / CD3 / CCR7 / CD45RA pour les lymphocytes T. De plus, afin d’étudier les capacités fonctionnelles des lymphocytes B CD19+, la réponse antigène-spécifique au vaccin antitétanique a été mesurée par marquage avec des tétramères fluorescents de fragment C du toxoïde tétanique. Nos travaux ont mis en évidence des différences statistiquement significatives entre les enfants exposés non-infectés (ENI) nés de mères avec une charge virale détectable comparativement à ceux nés de mères avec une charge virale indétectable. À la naissance, les enfants ENI nés de mères avec une charge virale détectable avaient significativement moins de lymphocytes B totaux, plus de lymphocytes B mémoires classiques, activés, plasmablastes et lymphocytes T CD8+ mémoires centrales. À 6 mois, ils avaient significativement plus de lymphocytes B naïfs et significativement moins de lymphocytes T CD8+ effecteurs mémoires. À 12 mois d’âge, ils avaient significativement plus de lymphocytes B et T CD8+ totaux; significativement moins de lymphocytes T CD4+ totaux et leurs lymphocytes T affichaient un profil significativement plus activé (plus de cellules mémoires). L’analyse de la réponse antigène-spécifique a révélé une fréquence plus élevé de lymphocytes B mémoires IgM+ suggérant que les enfants nés de mères avec une virémie détectable ont plus de mal à établir une mémoire immunitaire efficace face au vaccin antitétanique. Nos données suggèrent qu’il y a exposition durant le premier trimestre de grossesse à la virémie maternelle et que cette exposition impacte le système immunitaire en développement du fœtus. Les mécanismes sous-jacents causant ces anomalies doivent encore être élucidés et l’épuisement du compartiment T à la naissance et à 6 mois reste à être investigué. Dans un pays industrialisé où l’accès aux soins est facilité, ces anomalies ont des conséquences modérées mais dans des pays à faible et moyen revenu, les conséquences peuvent être beaucoup plus tragiques voir fatales.

Prevalencia de síntomas relacionados con desórdenes musculo esqueléticos en trabajadores de una empresa dedicada a la venta y distribución de medicamentos y equipos médicos - Colombia, 2015.

Introducción: Los Desórdenes Musculo-Esqueléticos (DME) tienen origen multifactorial. En Colombia corresponden al principal grupo diagnóstico en procesos relacionados con la determinación de origen y pérdida de capacidad laboral. Objetivo: Determinar la relación entre síntomas musculo-esqueléticos y factores relacionados con la carga física en trabajadores de una empresa dedicada a la venta y distribución de medicamentos y equipos médicos, Bogotá (Colombia), en el año 2015. Materiales y Métodos: Estudio de corte transversal en 235 trabajadores. Se incluyeron variables sociodemográficas, ocupacionales y las relacionadas con los síntomas musculoesqueléticos y carga física. Se utilizó en cuestionario ERGOPAR. Para el análisis se utilizó la Prueba Exacta de Fisher, el Odds Ratio (OR) con el Intervalo de Confianza (IC) del 95%. Se realizó el análisis Multivariado con Regresión Logística Binaria. Resultados: La prevalencia de síntomas relacionados con DME fue de 79,2%, siendo más prevalente en cuello, hombros y columna dorsal (48,1%), seguido por columna lumbar (35,3%). Se encontró una asociación entre síntomas en cuello, hombros y/o columna dorsal con el sexo femenino (p=0,005, OR=2,33, 95%IC: 1,2-4,2); adoptar postura bípeda menos de 30 minutos (p=0,004, OR=3,34, 95%IC: 1,4-7,6); adoptar postura cabeza/cuello inclinado hacia delante entre 30 minutos y 2 horas (p=0,007, OR=3,25, 95%IC :1,3-7,7) y en columna lumbar con adoptar postura espalda/tronco hacia delante entre 30 minutos y 2 horas (p=0,001, OR=4,27, 95%IC: 1,7-10,3); y la antigüedad en el cargo entre 1 y 5 años (p=0,009, OR=3,47, 95%IC: 1,3-8,8). Conclusión: Las posturas bípedas con y sin desplazamiento, inclinaciones de tronco y cabeza, transporte manual de cargas, sexo femenino, antigüedad en el cargo y edad están asociadas conjuntamente al riesgo para presentar DME.

Asociación entre la escala de riesgo Framingham y el puntaje de calcio coronario

Introducción: Entre las diferentes herramientas clínicas para evaluar la presencia de enfermedad coronaria mediante puntajes, la más usada es la Escala de Riesgo cardiovascular de Framingham. Desde hace unos años, se creó el puntaje de calcio coronario el cual mide el riesgo cardiovascular según la presencia de placas ateromatosas vistas por tomografía computarizada. Se evaluó la asociación entre la escala de Framigham y el puntaje de calcio coronario en una población de sujetos sanos asintomáticos. Metodología: Se realizó un estudio transversal para evaluar la asociación entre el puntaje de calcio coronario y la escala de Framingham en sujetos asintomáticos que se practicaron exámen médico preventivo en la Fundación Cardioinfantil- Instituto de Cardiología (FCI-IC) en el periodo comprendido entre 1 de Julio 2011 hasta el 31 de octubre de 2015. Resultados: Se evaluaron 262 pacientes en total. La prevalencia de riesgo cardiovascular fue bajo en un 77.86% de la población, medio en 18.70% y alto en 3.44%, según la escala de Framingham. El riesgo cardiovascular según el puntaje de Calcio coronario fue nulo 70.99%, bajo en 21.75%, medio en 4.19%, severo en 3.05%. Se encontró una asociación entre ambos puntajes para riesgo estadísticamente significativa (p0,00001) Discusión: El riesgo cardiovascular establecido por escala de Framingham se relaciona de forma significativa con la presencia de placas aterioscleróticas. El estudio demostró que en una muestra de sujetos asintomáticos, hay una alteración estructural coronaria temprana.

Immunodeficiency at the start of combination antiretroviral therapy in low-, middle-, and high-income countries

OBJECTIVE To describe the CD4 cell count at the start of combination antiretroviral therapy (cART) in low-income (LIC), lower middle-income (LMIC), upper middle-income (UMIC), and high-income (HIC) countries. METHODS Patients aged 16 years or older starting cART in a clinic participating in a multicohort collaboration spanning 6 continents (International epidemiological Databases to Evaluate AIDS and ART Cohort Collaboration) were eligible. Multilevel linear regression models were adjusted for age, gender, and calendar year; missing CD4 counts were imputed. RESULTS In total, 379,865 patients from 9 LIC, 4 LMIC, 4 UMIC, and 6 HIC were included. In LIC, the median CD4 cell count at cART initiation increased by 83% from 80 to 145 cells/μL between 2002 and 2009. Corresponding increases in LMIC, UMIC, and HIC were from 87 to 155 cells/μL (76% increase), 88 to 135 cells/μL (53%), and 209 to 274 cells/μL (31%). In 2009, compared with LIC, median counts were 13 cells/μL [95% confidence interval (CI): -56 to +30] lower in LMIC, 22 cells/μL (-62 to +18) lower in UMIC, and 112 cells/μL (+75 to +149) higher in HIC. They were 23 cells/μL (95% CI: +18 to +28 cells/μL) higher in women than men. Median counts were 88 cells/μL (95% CI: +35 to +141 cells/μL) higher in countries with an estimated national cART coverage >80%, compared with countries with <40% coverage. CONCLUSIONS Median CD4 cell counts at the start of cART increased 2000-2009 but remained below 200 cells/μL in LIC and MIC and below 300 cells/μL in HIC. Earlier start of cART will require substantial efforts and resources globally.

Understanding informal payments in health care: motivation of health workers in Tanzania

BACKGROUND: There is growing evidence that informal payments for health care are fairly common in many low- and middle-income countries. Informal payments are reported to have a negative consequence on equity and quality of care; it has been suggested, however, that they may contribute to health worker motivation and retention. Given the significance of motivation and retention issues in human resources for health, a better understanding of the relationships between the two phenomena is needed. This study attempts to assess whether and in what ways informal payments occur in Kibaha, Tanzania. Moreover, it aims to assess how informal earnings might help boost health worker motivation and retention. METHODS: Nine focus groups were conducted in three health facilities of different levels in the health system. In total, 64 health workers participated in the focus group discussions (81% female, 19% male) and where possible, focus groups were divided by cadre. All data were processed and analysed by means of the NVivo software package. RESULTS: The use of informal payments in the study area was confirmed by this study. Furthermore, a negative relationship between informal payments and job satisfaction and better motivation is suggested. Participants mentioned that they felt enslaved by patients as a result of being bribed and this resulted in loss of self-esteem. Furthermore, fear of detection was a main demotivating factor. These factors seem to counterbalance the positive effect of financial incentives. Moreover, informal payments were not found to be related to retention of health workers in the public health system. Other factors such as job security seemed to be more relevant for retention. CONCLUSION: This study suggests that the practice of informal payments contributes to the general demotivation of health workers and negatively affects access to health care services and quality of the health system. Policy action is needed that not only provides better financial incentives for individuals but also tackles an environment in which corruption is endemic.

The Ethics of Ethics Reviews in Global Health Research: Case Studies Applying a New Paradigm

With increasing calls for global health research there is growing concern regarding the ethical challenges encountered by researchers from high-income countries (HICs) working in low or middle-income countries (LMICs). There is a dearth of literature on how to address these challenges in practice. In this article, we conduct a critical analysis of three case studies of research conducted in LMICs.We apply emerging ethical guidelines and principles specific to global health research and offer practical strategies that researchers ought to consider. We present case studies in which Canadian health professional students conducted a health promotion project in a community in Honduras; a research capacity-building program in South Africa, in which Canadian students also worked alongside LMIC partners; and a community-university partnered research capacity-building program in which Ecuadorean graduate students, some working alongside Canadian students, conducted community-based health research projects in Ecuadorean communities.We examine each case, identifying ethical issues that emerged and how new ethical paradigms being promoted could be concretely applied.We conclude that research ethics boards should focus not only on protecting individual integrity and human dignity in health studies but also on beneficence and non-maleficence at the community level, explicitly considering social justice issues and local capacity-building imperatives.We conclude that researchers from HICs interested in global health research must work with LMIC partners to implement collaborative processes for assuring ethical research that respects local knowledge, cultural factors, the social determination of health, community participation and partnership, and making social accountability a paramount concern.

Promoting the health of marginalized populations in Ecuador through international collaboration and educational innovations

This paper examines two innovative educational initiatives for the Ecuadorian public health workforce: a Canadian-funded Masters programme in ecosystem approaches to health that focuses on building capacity to manage environmental health risks sustainably; and the training of Ecuadorians at the Latin American School of Medicine in Cuba (known as Escuela Latinoamericana de Medicina in Spanish). We apply a typology for analysing how training programmes address the needs of marginalized populations and build capacity for addressing health determinants. We highlight some ways we can learn from such training programmes with particular regard to lessons, barriers and opportunities for their sustainability at the local, national and international levels and for pursuing similar initiatives in other countries and contexts. We conclude that educational efforts focused on the challenges of marginalization and the determinants of health require explicit attention not only to the knowledge, attitudes and skills of graduates but also on effectively engaging the health settings and systems that will reinforce the establishment and retention of capacity in low- and middle-income settings where this is most needed.

Seasonal persistence of northern low- and middle-latitude anomalies of ozone and other trace gases in the upper stratosphere

Analysis of observed ozone profiles in Northern Hemisphere low and middle latitudes reveals the seasonal persistence of ozone anomalies in both the lower and upper stratosphere. Principal component analysis is used to detect that above 16 hPa the persistence is strongest in the latitude band 15–45°N, while below 16 hPa the strongest persistence is found over 45–60°N. In both cases, ozone anomalies persist through the entire year from November to October. The persistence of ozone anomalies in the lower stratosphere is presumably related to the wintertime ozone buildup with subsequent photochemical relaxation through summer, as previously found for total ozone. The persistence in the upper stratosphere is more surprising, given the short lifetime of Ox at these altitudes. It is hypothesized that this “seasonal memory” in the upper stratospheric ozone anomalies arises from the seasonal persistence of transport-induced wintertime NOy anomalies, which then perturb the ozone chemistry throughout the rest of the year. This hypothesis is confirmed by analysis of observations of NO2, NOx, and various long-lived trace gases in the upper stratosphere, which are found to exhibit the same seasonal persistence. Previous studies have attributed much of the year-to-year variability in wintertime extratropical upper stratospheric ozone to the Quasi-Biennial Oscillation (QBO) through transport-induced NOy (and hence NO2) anomalies but have not identified any statistical connection between the QBO and summertime ozone variability. Our results imply that through this “seasonal memory,” the QBO has an asynchronous effect on ozone in the low to midlatitude upper stratosphere during summer and early autumn.
