Culturally adapted mobile application for optimizing metabolic control in type 1 diabetes: a pilot study / Aplicación móvil adaptada desde el punto de vista cultural para optimizar el control metabólico en la diabetes tipo 1: estudio piloto / Aplicativo móvel culturalmente adaptado para otimizar o controle metabólico do diabetes tipo 1: estudo-piloto

[ABSTRACT]. Objective. To evaluate whether use of a culturally adapted mobile application (app) for adolescents with type 1 diabetes is associated with improved metabolic control. Methods. The Dominican Republic’s National Institute of Diabetes, Endocrinology, and Nutrition and the Learning to Live clinic recruited 23 pediatric participants for the study. Blood tests were performed before and after use of the app for a period of 3 months. Based on the user profile, participants were encouraged to use the app’s bolus insulin calculator after each meal. The app included a list of regionally and culturally specific foods, color-coded to indicate a high glycemic index (GI) as red; medium GI as yellow; and low GI as green. The color-coding was designed to assist participants in making healthier eating choices. Results. There were statistically significant improvements in lipid profile. Mean high-density lipoprotein values rose to acceptable levels, while low-density lipoproteins and triglyceride levels fell to the recommended values. The overall quality of life increased, although glycated hemoglobin levels showed no statistically significant changes. Conclusion. The findings of this study suggest that using this culturally tailored app can help young patients with type 1 diabetes to improve metabolic health.

Confined within a sugarcane monoculture: A participatory assessment of water pollution and potential health risks in the community of El Tiple, Colombia.

Communities neighboring monoculture plantations are vulnerable to different forms of pollution associated with agro-industrial operations. Herein, we examine the case of El Tiple, a rural Afro descendant community embedded within one of the largest sugarcane plantations in the Americas. We implemented a participatory approach to assess water pollution, exposure via water ingestion, and non-carcinogenic health risks associated with the use of local water sources available to the community. We conducted household surveys to unveil demographic characteristics and family dynamics linked to water consumption. Additionally, we measured water quality parameters and assessed the concentration glyphosate, its major metabolite (aminomethylphosphonic acid) and metals and metalloids. Drinking water El Tiple households is sourced from three primary sources: the local aqueduct system, water delivery trucks, and private deep wells. Tests on water samples from both the local aqueduct and delivery trucks showed no traces of pesticides, metals, or metalloids surpassing regulatory limits set by Colombian or EPA standards. However, we found concentration of contaminants of primary concern, including mercury (up to 0.0052 ppm) and lead (up to 0.0375 ppm) that exceed the permissible regulatory thresholds in water from groundwater wells. Residents of the peripheric subdivisions of El Tiple are four times more reliant on well water extraction than residents of the central area of the town due to lack of access to public drinking water and sanitation infrastructure. Finally, adult women and school-age children have a higher health risk associated with exposure to local pollutants than adult men due to their constant presence in the town. We conclude that expanding the coverage of clean water and sanitation infrastructure to include all households of the community would be the most recommended measure to minimize exposure and risk via ingestion of water pollutants.

Dominican Adolescents' Preferences for Content, Design, and Functionality of a Mobile Application for Type 1 Diabetes Mellitus Self-management.

OBJECTIVE: The purpose of this interdisciplinary study was to determine Dominican adolescents' preferences for the content, functionality (i.e. food's glycemic index list, and amount of insulin based on foods' carbohydrate count), and design of a culturally and linguistically relevant mobile application (app) for type 1 diabetes mellitus (T1DM) self-management. The app would facilitate T1DM self-management education and support by addressing providers' challenges in monitoring patients' disease progression and promoting patient adherence to recommended lifestyle changes. Findings inform an app development process that considers the linguistic and cultural values, norms, and structures of people with T1DM and their providers in the Dominican Republic. METHODS: Phone interviews were conducted with 23 adolescents (14 to 18 years of age), using a semistructured questionnaire. The research team conducted the data analysis using NVivo through a deductive and inductive approach. RESULTS: The findings suggest that, regardless of the context, adolescents with T1DM desire similar features and functionalities in a self-management app. Overall, participants preferred an app with a graphic format that has accessible information, a straightforward design, and instructional videos. Participants also desired that an app provide information and reminders about proper eating and insulin administration timing and be a vehicle to access a social network to foster mutual support and encouragement. CONCLUSIONS: Our study highlights adolescents' perspectives on components for inclusion in an app for T1DM self-management. Participants' recommendations for the app's potential usability, contents, and design features will be used to guide the development of a new app to promote engagement and foster better health outcomes.

Impact of Haemophilus influenzae type b conjugate vaccine on bacterial meningitis in the Dominican Republic

OBJECTIVES: Widespread use of Haemophilus influenzae type b (Hib) vaccines has dramatically reduced the burden of Hib disease throughout the Americas. Few studies have evaluated the impact of Hib vaccination on non-culture-confirmed disease. This study analyzed trends in probable bacterial meningitis before and after the introduction of Hib vaccine in the Dominican Republic and estimated vaccine effectiveness against Hib meningitis. METHODS: Meningitis cases among children < 5 years of age were identified from admission records of the main pediatric hospital in Santo Domingo during 1998 - 2004. Laboratory criteria were used to classify meningitis cases with probable bacterial etiology; confirmed cases had positive bacterial culture or antigen detection in cerebrospinal fluid. Cumulative incidence rates of confirmed and probable bacterial meningitis were calculated for children living in the National District. Confirmed cases of Hib meningitis were enrolled in a case control study with age- and neighborhood-matched control children to calculate vaccine effectiveness. RESULTS: Before vaccine introduction, annual rates of meningitis with probable bacterial etiology were 49 cases per 100000 children < 5 years old; Hib accounted for 60 percent of confirmed bacterial cases. During 2002 - 2004, after vaccine introduction, annual rates of probable bacterial meningitis were 65 percent lower at 16 cases per 100000, and Hib accounted for 26 percent of confirmed cases. Rates of Hib meningitis and probable bacterial meningitis with no determined etiology declined by 13 and 17 cases per 100000, respectively. CONCLUSIONS: Introduction of Hib vaccine substantially reduced the incidence of confirmed and probable bacterial meningitis in the Dominican Republic. The estimated impact of Hib vaccination was twice as great when non-culture-confirmed disease was included

OBJETIVOS: El uso generalizado de la vacuna contra Haemophilus influenzae tipo b (Hib) ha permitido reducir radicalmente la carga de enfermedad por Hib en las Américas. Pocos estudios han evaluado el impacto de la vacunación contra Hib sobre los casos no confirmados mediante cultivo. En este estudio se analizaron las tendencias en el número de casos probables de meningitis bacteriana antes y después de la introducción de la vacuna contra Hib en la República Dominicana y se estimó la eficacia de la vacuna contra la meningitis. MÉTODOS: Se identificaron los casos de meningitis en niños menores de 5 años a partir de los registros de ingreso del principal hospital pediátrico de Santo Domingo entre 1998 y 2004. Los casos de meningitis con probable etiología bacteriana se clasificaron según criterios de laboratorio; los casos confirmados contaban con cultivo bacteriano positivo o detección de antígenos específicos en el líquido cefalorraquídeo. Se calcularon las tasas de incidencia acumulada de casos confirmados y probables de meningitis en los niños que vivían en el Distrito Nacional. Los casos confirmados de meningitis por Hib se incorporaron a un estudio de casos y controles -pareados según la edad y el barrio de residencia- para calcular la eficacia de la vacuna. RESULTADOS: Antes de la introducción de la vacuna, la tasa anual de meningitis de posible etiología bacteriana era de 49 casos por 100 000 niños menores de 5 años; de los casos confirmados de origen bacteriano, 60 por ciento fue por Hib. En el período 2002-2004, después de la introducción de la vacuna, la tasa anual de meningitis de posible etiología bacteriana fue de 16 casos por 100 000, es decir 65 por ciento más baja, y 26 por ciento de los casos confirmados correspondieron a Hib. Las tasas de meningitis por Hib y de posible origen bacteriano de etiología desconocida se redujeron en 13 y 17 casos por 100 000, respectivamente. CONCLUSIONES: La introducción de la vacuna contra Hib redujo sustancialmente la incidencia de casos de meningitis confirmados y probables en la República Dominicana. El impacto estimado de la vacunación contra Hib fue dos veces mayor cuando se consideraron los casos no confirmados mediante cultivo.

Epidemiology of needlesticks and other sharps injuries and injection safety practices in the Dominican Republic.

BACKGROUND: Contaminated sharps, such as needles, lancets, scalpels, broken glass, specimen tubes, and other instruments, can transmit bloodborne pathogens such as HIV, hepatitis B (HBV), and hepatitis C viruses (HCV). METHODS: Observation of facilities and injections and questionnaire-guided interviews were conducted in 2005 among health care workers (HCWs) in 2 public hospitals in Santo Domingo and 136 public immunization clinics (IC) in the Dominican Republic. Injection practices and sharps injuries (SIs) in health care facilities in the Dominican Republic were assessed in cross-sectional surveys to identify areas in which preventive efforts might be directed to make injection practices safer. RESULTS: Of the 304 hospital HCWs and 136 ICs HCWs interviewed, 98 (22.3%) reported > or =1 SIs during the previous 12 months. ICs had a lower incidence (13 per 100 per person-years [p-y]) of SIs than hospitals (65 per 100 p-y) (P < .0001). Unsafe needle recapping was observed in 98% of all injections observed at hospitals but in only 12% of injections at ICs (P < .0001). Sharps were observed improperly disposed in regular waste containers in 24 (92%) of 26 areas at which injections are prepared at the hospitals but in only 11 (8%) of 136 ICs (P < .0001). Training in injection safety was received by 4% of HCWs in hospitals but by 77% in ICs (P < .001). Of 425 HCWs, 247 (58%) were fully immunized against hepatitis B. There was a higher risk of SIs among staff dentists (adjusted relative risks [aRR], 5.9; 95% confidence interval [CI]: 2.8-12.6), resident physicians (aRR, 3.5; 95% CI: 1.8-6.9), and those who gave > or =11 therapeutic injections per day (aRR, 1.6; 95% CI: 1.1-2.4). CONCLUSION: Injection practices at ICs were safer than those found at public hospitals. Preventive strategies to lower SIs in public hospitals should include regular training of hospital staff to minimize needle recapping and improper disposal, among other interventions to reduce the dangers of needles.
