ABSTRACT
Introducción: la yerba mate (Ilex paraguariensis) constituye un recurso alimentario autóctono, formando parte de la tradición y cultura alimentaria del Paraguay. Sin embargo, existen pocos estudios locales sobre los hábitos de consumo y preferencias por los paraguayos. Objetivo: describir los hábitos de consumo de la yerba mate (Ilex paraguariensis) en el Departamento Central en el 2022. Metodología: estudio descriptivo, transversal, con datos primarios, realizado en el Departamento Central de Paraguay. Muestreo no probabilístico en racimos. Instrumento de elaboración propia, diseñado como encuesta digital en la plataforma Google Form® (EE.UU.). Las variables fueron agrupadas en datos demográficos, relacionados al consumo de mate, tereré y cocido, procesados en Microsoft Excel® (EE.UU.) y EPI INFO® 7.0 (EE.UU.). Resultados: participaron 207 personas, la mayoría contaban entre 18 a 40 años, sexo femenino (83,22 %, 119), solteros, universitarios. El consumo más frecuente fue mate+ tereré+ cocido (43,96 %, 91) y tereré + cocido (14,01 %, 29). Todos los encuestados percibían más de dos salarios mínimos, y eran trabajadores de tiempo completo. El 81,64 % (169) consumían tereré, 69,08 % (143) mate, 80,23 % (138) cocido. El tipo de yerba más consumido fue la "compuesta con hierbas medicinales", con un promedio de 1,5 Litros diarios. Conclusión: las formas más consumidas son tereré, cocido y mate, el tipo de yerba es la compuesta con el agregado de hierbas medicinales. Se sugieren realizar estudios poblacionales más amplios sobre el consumo de bebidas a base de yerba mate en Paraguay, así como ampliar estudios sobre las posibles interacciones e inocuidad entre la yerba mate con hierbas medicinales.
Introduction: yerba mate (Ilex paraguariensis) constitutes a native food resource, forming part of the food tradition and culture of Paraguay. However, there are few local studies on the consumption habits and preferences of Paraguayans. Objective: to describe the consumption habits of yerba mate (Ilex paraguariensis) in the Departamento Central in 2022. Methodology: descriptive, cross-sectional study, with primary data, carried out in the Departamento Central of Paraguay. Non-probability cluster sampling. Self-developed instrument, designed as a digital survey on the Google Form® platform (USA). The variables were grouped into demographic data, related to the consumption of mate, tereré and cocido, processed in Microsoft Excel® (USA) and EPI INFO® 7.0 (USA). Results: people participated was 207, the majority were between 18 and 40 years old, female (83.22 %, 119), single, university students. The most frequent consumption was mate + tereré + cooked (43.96 %, 91) and tereré + cooked (14.01 %, 29). All respondents received more than two minimum wages, and were full-time workers. 81.64 % (169) consumed tereré, 69.08 % (143) consumed mate, 80.23 % (138) cooked. The most consumed type of herb was "composed with medicinal herbs", with an average of 1.5 Liters per day. Conclusion: the most consumed forms are tereré, cooked and mate, the type of yerba is the one composed with the addition of medicinal herbs. It is suggested to carry out larger population studies on the consumption of yerba mate-based drinks in Paraguay, as well as expand studies on the possible interactions and safety between yerba mate and medicinal herbs.
ABSTRACT
BACKGROUND: Ensuring the quality of malaria medicines is crucial in working toward malaria control and eventual elimination. Unlike other validated tests that can assess all critical quality attributes, which is the standard for determining the quality of medicines, basic tests are significantly less expensive, faster, and require less skilled labour; yet, these tests provide reproducible data and information on several critical quality attributes, such as identity, purity, content, and disintegration. Visual and physical inspection also provides valuable information about the manufacturing and the labelling of medicines, and in many cases this inspection is sufficient to detect counterfeit medicines. The Promoting the Quality of Medicines (PQM) programme has provided technical assistance to Amazon Malaria Initiative (AMI) countries to implement the use of basic tests as a key screening mechanism to assess the quality of malaria medicines available to patients in decentralized regions. METHODS: Trained personnel from the National Malaria Control Programmes (NMCPs), often in collaboration with country's Official Medicine Control Laboratory (OMCL), developed country- specific protocols that encompassed sampling methods, sample analysis, and data reporting. Sampling sites were selected based on malaria burden, accessibility, and geographical location. Convenience sampling was performed and countries were recommended to store the sampled medicines under conditions that did not compromise their quality. Basic analytical tests, such as disintegration and thin layer chromatography (TLC), were performed utilizing a portable mini-laboratory. RESULTS: Results were originally presented at regional meetings in a non-standardized format that lacked relevant medicines information. However, since 2008 information has been submitted utilizing a template specifically developed by PQM for that purpose. From 2005 to 2010, the quality of 1,663 malaria medicines from seven AMI countries was evaluated, mostly collected from the public sector, 1,445/1,663 (86.9%). Results indicate that 193/1,663 (11.6%) were found not to meet quality specifications. Most failures were reported during visual and physical inspection, 142/1663 (8.5%), and most of these were due to expired medicines, 118/142 (83.1%). Samples failing TLC accounted for 27/1,663 (1.6%) and those failing disintegration accounted for 24/1,663 (1.4%). Medicines quality failures decreased significantly during the last two years. CONCLUSIONS: Basic tests revealed that the quality of medicines in the public sector improved over the years, since the implementation of this type of quality monitoring programme in 2005. However, the lack of consistent confirmatory tests in the quality control (QC) laboratory, utilizing methods that can also evaluate additional quality attributes, could still mask quality issues. In the future, AMI countries should improve coordination with their health authorities and their QC lab consistently, to provide a more complete picture of malaria medicines quality and support the implementation of corrective actions. Facilities in the private and informal sectors also should be included when these sectors constitute an important source of medicines used by malaria patients.

Se realizó una evaluación in vivo de la eficacia de la cloroquina para el tratamiento de la malaria por Plasmodium vivax, en elsitio centinela de Palmar Chico, Municipio de Yacuiba, Provincia Gran Chaco, Departamento de Tarija al Sur de Bolivia. Fueronincluidos en el estudio 61 pacientes entre 5 y 59 años de edad que presentaban monoinfección por P. vivax. Todos los pacientesrecibieron una dosis total de cloroquina de 25 mg/Kg en 3 días (10mg/Kg el primer día; 7,5 mg/Kg el segundo y tercer días).De acuerdo al protocolo estandarizado de la OPS/OMS, todos los pacientes fueron seguidos por 28 días (controles clínicos yparasitológicos). Se completó el seguimiento de 60 pacientes, ninguno de los pacientes tuvo recurrencias de la parasitemia opresentó manifestaciones clínicas después del tercer día de tratamiento. Este estudio mostró 100% de sensibilidad de P. vivaxa la cloroquina, lo que justifica su permanencia en la política de medicamentos antimaláricos como la droga más adecuada parael tratamiento de las infecciones por P. vivax en el Sur de Bolivia.
We carried out an evaluation in vivoof the chloroquine efficacy for the treatment of malaria by Plasmodium vivax, in the sentinelsite of Palmar Chico, Municipality of Yacuiba, Province Gran Chaco, Department of Tarija to the South of Bolivia. Sixty one patientsaged between 5 and 59 years that presented monoinfection by P. vivaxwere included in the study. All patient received undersupervision a total dose of chloroquine 25mg/kg over three days (10mg/kg on the first day; 7.5 mg/kg on the second and thirddays). According the standardized protocol of the PAHO/WHO, all patients were followed-up for 28 days (clinical and parasitologicalcontrols). Sixty patients completed the follow-up, none of the patients had recurrences of parasitemia or presented clinicalmanifestations after third day of treatment. This study showed 100% of sensibility from P. vivax to chloroquine, what justifies theirpermanency in the antimalarial drug policy as the most adequate drug for the treatment of the P. vivax infections in the South of Bolivia.
