The effect of weather and climate on dengue outbreak risk in Peru, 2000-2018: A time-series analysis.

BACKGROUND: Dengue fever is the most common arboviral disease in humans, with an estimated 50-100 million annual infections worldwide. Dengue fever cases have increased substantially in the past four decades, driven largely by anthropogenic factors including climate change. More than half the population of Peru is at risk of dengue infection and due to its geography, Peru is also particularly sensitive to the effects of El Niño Southern Oscillation (ENSO). Determining the effect of ENSO on the risk for dengue outbreaks is of particular public health relevance and may also be applicable to other Aedes-vectored viruses. METHODS: We conducted a time-series analysis at the level of the district-month, using surveillance data collected from January 2000 to September 2018 from all districts with a mean elevation suitable to survival of the mosquito vector (<2,500m), and ENSO and weather data from publicly-available datasets maintained by national and international agencies. We took a Bayesian hierarchical modeling approach to address correlation in space, and B-splines with four knots per year to address correlation in time. We furthermore conducted subgroup analyses by season and natural region. RESULTS: We detected a positive and significant effect of temperature (°C, RR 1.14, 95% CI 1.13, 1.15, adjusted for precipitation) and ENSO (ICEN index: RR 1.17, 95% CI 1.15, 1.20; ONI index: RR 1.04, 95% CI 1.02, 1.07) on outbreak risk, but no evidence of a strong effect for precipitation after adjustment for temperature. Both natural region and season were found to be significant effect modifiers of the ENSO-dengue effect, with the effect of ENSO being stronger in the summer and the Selva Alta and Costa regions, compared with winter and Selva Baja and Sierra regions. CONCLUSIONS: Our results provide strong evidence that temperature and ENSO have significant effects on dengue outbreaks in Peru, however these results interact with region and season, and are stronger for local ENSO impacts than remote ENSO impacts. These findings support optimization of a dengue early warning system based on local weather and climate monitoring, including where and when to deploy such a system and parameterization of ENSO events, and provide high-precision effect estimates for future climate and dengue modeling efforts.

[Text messaging to improve patient adherence in haart: randomized controlled trial]. / Envío de mensajes de texto para mejorar la adherencia de pacientes en targa: ensayo aleatorizado controlado.

OBJECTIVES.: To assess the efficacy of a text messaging (SMS) strategy to improve appointment attendance, treatment adherence, and biological markers (viral load and CD4) in continuous patients with high activity antiretroviral therapy (HAART) who were late to their last scheduled appointment. MATERIALS AND METHODS.: A randomized controlled trial implemented in Via Libre, a non-governmental organization (NGO) that provides services to people living with human immunodeficiency virus (HIV) in Lima, Peru, was conducted, where 166 follow-up patients were randomized: 82 participants received SMS for six months and 84 participants received standard care. RESULTS.: Patients in the intervention group: 93.9% were men and had a median of 5.1 years in HAART; in the control group: 94.1% were men and a median of 5.3 years in HAART. In the intervention group, patients attended their scheduled medical appointments more frequently than those in the control group (RR=1.89, 95% CI 1.21-2.97) during the six months of intervention. Comparing the viral load level and CD4 level, no differences were found (p=0.930 and p=0.905, respectively). Adherence to treatment measured by self-report was higher in the intervention group (p<0.001). CONCLUSIONS.: The results of this study suggest that sending SMS for six months may improve appointment attendance and adherence to treatment in continuing patients on HAART.

OBJETIVOS: . Evaluar la eficacia de una estrategia de envío de mensajes de texto (SMS) en la mejora de la asistencia a citas, adherencia al tratamiento y marcadores biológicos (carga viral y CD4) en pacientes continuadores con tratamiento antirretroviral de gran actividad (TARGA) que asistieron a destiempo a su última cita programada. MATERIALES Y MÉTODOS.: Se realizó un ensayo aleatorizado controlado implementado en Vía Libre, una organización no gubernamental (ONG) que brinda servicios a personas viviendo con el virus de la inmunodeficiencia humana (VIH) en Lima. Se aleatorizaron 166 pacientes continuadores: 82 participantes recibieron SMS por seis meses y 84 participantes la atención estándar. RESULTADOS.: Los pacientes en el grupo de intervención, un 93,9% fueron hombres y tenían una mediana de 5,1 años en TARGA; en cambio en el grupo control, un 94,1% fueron hombres y una mediana de 5,3 años en TARGA. En el grupo de intervención, los pacientes asistieron con más frecuencia que aquellos en el grupo control a sus citas médicas programadas (RR=1,89; IC 95%: 1,21-2,97) en los seis meses de intervención. Al comparar el nivel de carga viral y el nivel de CD4 no se encontraron diferencias (p=0,930 y p=0,905, respectivamente). La adherencia al tratamiento medida por autorreporte fue mayor en el grupo de intervención (p<0,001). CONCLUSIONES.: Los resultados en este estudio sugieren que el envío de SMS por seis meses puede mejorar la asistencia a citas y la adherencia al tratamiento en pacientes continuadores en TARGA.

[Preliminary results of the strengthening of the national death registry information system]. / Resultados preliminares del fortalecimiento del sistema informático nacional de defunciones.

Peru has a low coverage of deaths with a cause of death (54%) and a poor-quality registration of causes of death, as about 30% of causes of death are classified as poorly-defined or not very useful for the formulation of public policies. In response to these problems, the Ministry of Health, together with other government agencies, with the support of the Bloomberg Philanthropies "Data for Health Initiative," is implementing the National Death Registry Information System (SINADEF). The objective of this article is to describe the process of strengthening the mortality information system in Peru, focused on the implementation of SINADEF. The activities that have been carried out are described in the following areas: a) Management of the mortality information system, b) Process standardization, c) Use of information and communication technology, d) Coverage of deaths with medical certificate, e) Improvement of the quality of information, f) Development of studies, and g) Monitoring of processes. Since the implementation of SINADEF in August 2016 until July 2018, 28,407 users of the SINADEF application have been created and a total of 122,411 deaths have been registered. The quality of data recording, including the cause of death, has been improved, while low coverage of deaths with a cause of death still persists.

Matching comprehensive health insurance reimbursements to their real costs: the case of antenatal care visits in a region of Peru.

BACKGROUND: Prepaid contributory systems are increasingly being recognized as key mechanisms in achieving universal health coverage in low and middle-income countries. Peru created the Seguro Integral de Salud (SIS) to increase health service use amongst the poor by removing financial barriers. The SIS transfers funds on a fee-for-service basis to the regional health offices to cover recurrent cost (excluding salaries) of pre-specified packages of interventions. We aim to estimate the full cost of antenatal care (ANC) provision in the Ventanilla District (Callao-Peru) and to compare the actual cost to the reimbursement rates provided by SIS. METHODS: The economic costs of ANC provision in 2011 in 8 of the 15 health centres in Ventanilla District were estimated from a provider perspective and the actual costs of those services covered by the SIS fee of $3.8 for each ANC visit were calculated. A combination of step-down and bottom-up costing methodologies was used. Sensitivity analysis was conducted to test the uncertainty around estimated parameters and model assumptions. Results are reported in 2011 US$. RESULTS: The total economic cost of ANC provision in all 8 health centres was $569,933 with an average cost per ANC visit of $31.3 (95 % CI $29.7-$33.5). Salaries comprised 74.4 % of the total cost. The average cost of the services covered by the SIS fee was $3.4 (95 % CI $3.0-$3.8) per ANC visit. Sensitivity analysis showed that the probability of the cost of an ANC visit being above the SIS reimbursed fee is 1.4 %. CONCLUSION: Our analysis suggests that the fee reimbursed by the SIS will cover the cost that it supposed to cover. However, there are significant threats to medium and longer term sustainability of this system as fee transfers represent a small fraction of the total cost of providing ANC. Increasing ANC coverage requires the other funding sources of the Regional Health Office (DIRESA) to adapt to increasing demand.

Miasis en prolapso uterino: presentación de un caso clínico / Myiasis in uterine prolapse: clinical case report

Reportamos el caso de una mujer de 95 años de Oxapampa-Perú con prolapso genital total infestado con larvas Cochliomyia hominivorax (díptera: calliphoridae). La miasis es una infestación del tejido producido por larvas de la mosca que se alimentan del tejido vivo o necrótico, sustancias líquidas o comida ingerida. Este es un caso poco común pues sólo se han reportado dos casos de miasis en prolapso uterino en la literatura. Las larvas fueron removidas manualmente y en la zona afectada se aplicó Coumaphos 300 mg, Propoxur 20 mg y Prontalbin 50 mg en polvo, usado en veterinaria, y además se trató con antibióticos de amplio espectro.

We report a case of a 95-years old woman, from Oxapampa-Peru, with fourth degree prolapses uterus infested with Cochliomyia hominivoraz (Dipteria: Calliphoridae). Myiasis is an infestation of tissue produced by flies’ larvae, or maggots, which feed on the host’s living or dead tissue, liquid body substances or ingested food. This is an uncommon condition and there have been on two cases of myiasis in prolapsed uterus reported in the literature. Maggots were removed manually, instilled with combination de Coumaphos 300 mg, Propoxur 20 mg and Prontalbin 50 Mg dusting powder, a veterinarian product, and treated with broad spectrum antibiotic.

Conocimientos sobre "su enfermedad" en pacientes con diabetes mellitus tipo 2 que acuden a hospitales generales / Knowledge about "their disease" in patients with type 2 diabetes mellitus treted in general hospitals

Objetivo: Se realizó un estudio cualitativo para medir el nivel de conocimiento, sobre diabetes mellitus 2 en pacientes hospitalizados del Hospital Nacional Arzobispo Loayza y el Hospital Nacional Cayetano Heredia. Material y métodos: Se realizaron entrevistas individuales que fueron grabadas y transcritas; y posteriormente interpretadas y calificadas. Se recogieron de las historias clínicas datos demográficos, complicaciones y tratamiento para contrastarlas con lasrespuestas dadas. Se incluyeron 31 pacientes. Resultados: La edad promedio fue 59,16 años. En 4 pacientes (12,9 %) el nivel de conocimiento sobre la enfermedad fue adecuado, en 15 (48,39 %) intermedio y en 12 (38,71 %) inadecuado. No se hallo asociación estadística entre el nivel de conocimiento con ninguna de las variables estudiadas. Conclusiones: El nivel de conocimientos sobre la diabetes en estos pacientes fue insuficiente. La información obtenida sugiere una educación deficiente de parte de los médicos hacia estos pacientes, lo que hace necesario implementar los programas educativos para ellos.

Objective: To determine knowledge about their disease in patients with type 2 diabetes mellitus treated in generalhospitals. Material and methods: A qualitative study was performed. Individual interviews were conducted with 31 in-hospital patients, under saturation principle. Recorded interviews were transcripted, interpreted and scored by authors. We also obtain demographics, complications and treatment from patients’ medical records data and contrast it with data provided. Results: Mean age was 59.16 years. Mean time since diagnosis was 9.5 years. Four (12.9%) patients had suitable level of knowledge, 15 (48.39%) intermediate level and 12 (38.71%) inadequate level of knowledge about their disease. We found no statistically significant association between level of knowledge and other variables evaluated. Conclusions: We found inadequate level of knowledge about their disease in this patients. Data suggests inadequate patient education from health providers, being necessary to improve educating programs.
