RESUMO

Undernutrition and a lack of learning opportunities can jeopardize long-term growth and development among infants in low- and middle-income countries. We conducted a 6-month 2 × 2 cluster-randomized trial to assess the effects of multiple micronutrient-fortified beverages and responsive caregiving interventions among infants 6-18 months in 72 community sectors in southwest Guatemala. We administered baseline and endline assessments of childhood development (Bayley Scales of Infant and Toddler Development) and socioemotional development (Brief Infant Toddler Socio-Emotional Assessment) and measured ferritin and hemoglobin on a subsample. The trial was analyzed using linear mixed models. At the baseline, the mean age (SD) was 13.0 (4.6) months, including 49% males, 32% who were stunted, 55% who were anemic, and 58% who were iron deficient. At the endline (n = 328/386, 85% retention), there was no synergistic effect on the fortified beverage and responsive caregiving intervention. Compared to the non-fortified beverage group, socioemotional development improved in the fortified beverage group. There were no intervention effects on other measures of child development, hemoglobin, or ferritin. In a setting with high rates of anemia and iron deficiency, a multiple micronutrient-fortified beverage improved infants' socioemotional development.

RESUMO

BACKGROUND: Given that the diabetes burden is rising rapidly in low- and middle-income countries, it is critical to understand perspectives of people living with diabetes in these settings. This qualitative study examines perceptions of causality and treatment among adults with type 2 diabetes in rural Indigenous communities of Guatemala. METHODS: We conducted semi-structured interviews with 29 people living with type 2 diabetes from a population survey in two majority Indigenous Guatemalan towns. Data were coded inductively and themes were elucidated by consensus. RESULTS: Participants emphasized strong emotional experiences and stress as perceived causes of diabetes, as well as diet and heritability. All participants took biopharmaceutical treatments, but many also endorsed diet, exercise, herbal remedies, and naturopathic products as important remedies. CONCLUSION: Perspectives from people living with diabetes in two rural Indigenous towns in Guatemala differ from the biomedical model of disease and have implications for clinical practice and program development.

RESUMO

Although causal links between tropical deforestation and palm oil are well established, linking this land use change to where the palm oil is actually consumed remains a distinct challenge and research gap. Supply chains are notoriously difficult to track back to their origin (i.e., the 'first-mile'). This poses a conundrum for corporations and governments alike as they commit to deforestation-free sourcing and turn to instruments like certification to increase supply chain transparency and sustainability. The Roundtable on Sustainable Palm Oil (RSPO) offers the most influential certification system in the sector, but whether it actually reduces deforestation is still unclear. This study used remote sensing and spatial analysis to assess the deforestation (2009-2019) caused by oil palm plantation expansion in Guatemala, a major palm oil source for international consumer markets. Our results reveal that plantations are responsible for 28% of deforestation in the region and that more than 60% of these plantations encroach on Key Biodiversity Areas. RSPO-certified plantations, comprising 63% of the total cultivated area assessed, did not produce a statistically significant reduction in deforestation. Using trade statistics, the study linked this deforestation to the palm oil supply chains of three transnational conglomerates - Pepsico, Mondelez International, and Grupo Bimbo - all of whom rely on RSPO-certified supplies. Addressing this deforestation and supply chain sustainability challenge hinges on three measures: 1) reform of RSPO policies and practices; 2) robust corporate tracking of supply chains; and 3) strengthening forest governance in Guatemala. This study offers a replicable methodology for a wide-range of investigations that seek to understand the transnational linkages between environmental change (e.g. deforestation) and consumption.

RESUMO

Adequate calcium intake is essential for health, especially for infants, children, adolescents, and women, yet is difficult to achieve with local foods in many low- and middle-income countries. Previous analysis found it was not always possible to identify food-based recommendations (FBRs) that reached the calcium population recommended intake (PRI) for these groups in Bangladesh, Guatemala, and Uganda. We have modeled the potential contribution of calcium-fortified drinking water or wheat flour to FBR sets, to fill the remaining intake gaps. Optimized diets containing fortified products, with calcium-rich local foods, achieved the calcium PRI for all target groups. Combining fortified water or flour with FBRs met dietary intake targets for adolescent girls in all geographies and allowed a reduction from 3-4 to the more feasible 1-2 FBRs. Water with a calcium concentration of 100 mg/L with FBRs was sufficient to meet calcium targets in Uganda, but higher concentrations (400-500 mg/L) were mostly required in Guatemala and Bangladesh. Combining calcium-fortified wheat flour at 400 mg/100 g of flour and the FBR for small fish resulted in diets meeting the calcium PRI in Bangladesh. Calcium-fortified water or flour could improve calcium intake for vulnerable populations, especially when combined with FBRs based on locally available foods.

RESUMO

INTRODUCTION: As of July 2022, a little over one-third of Guatemalans were fully vaccinated. While COVID-19 vaccination rates are not officially reported nationally by racial/ethnic groups, non-governmental organisations and reporters have observed that COVID-19 vaccination rates are especially low among high-risk Indigenous populations. We conducted one of the first studies on COVID-19 vaccine acceptance in Indigenous populations in the Central Highlands of Guatemala, which aimed to better understand the barriers to COVID-19 vaccine uptake and how to improve vaccine promotional campaigns. METHODS: In November 2021, we conducted eight focus group discussions (FGDs) with 42 Indigenous men and women and 16 in-depth interviews (IDIs) with community health workers, nurses and physicians in Chimaltenango and Sololá. Using a participatory design approach, our qualitative analysis used constant comparative methods to understand the inductive and deductive themes from the FGD and IDI transcripts. RESULTS: We found three major overarching barriers to vaccination within the sampled population: (1) a lack of available easily understandable, linguistically appropriate and culturally sensitive COVID-19 vaccine information; (2) vaccine access and supply issues that prevented people from being vaccinated efficiently and quickly; and (3) widespread misinformation and disinformation that prey on people's fears of the unknown and mistrust of the medical establishment and government. CONCLUSION: When developing COVID-19 vaccine messages, content should be culturally relevant, appropriate for low-literacy populations and in the languages that people prefer to speak. Promotional materials should be in multiple modalities (print, radio and social media) and also have specific Maya cultural references (dress, food and concepts of disease) to ensure messaging connects with intended targets. This study supports the need for more robust research into best practices for communicating about COVID-19 vaccines to marginalised communities globally and suggests that policy makers should invest in targeted local solutions to increase vaccine uptake.

RESUMO

Growing interest in how marginalised citizens can leverage countervailing power to make health systems more inclusive and equitable points to the need for politicised frameworks for examining bottom-up accountability initiatives. This study explores how political capabilities are manifested in the actions and strategies of Indigenous grassroots leaders of health accountability initiatives in rural Guatemala. Qualitative data were gathered through group discussions and interviews with initiative leaders (called defenders of the right to health) and initiative collaborators in three municipalities. Analysis was oriented by three dimensions of political capabilities proposed for evaluating the longer-term value of participatory development initiatives: political learning, reshaping networks and patterns of representation. Our findings indicated that the defenders' political learning began with actionable knowledge about defending the right to health and citizen participation. The defenders used their understanding of local norms to build trust with remote Indigenous communities and influence them to participate in monitoring to attempt to hold the state accountable for the discriminatory and deficient healthcare they received. Network reshaping was focused on broadening their base of support. Their leadership strategies enabled them to work with other grassroots leaders and access resources that would expand their reach in collective action and lend them more influence representing their problems beyond the local level. Patterns of representing their interests with a range of local and regional authorities indicated they had gained confidence and credibility through their evolving capability to navigate the political landscape and seek the right authority based on the situation. Our results affirm the critical importance of sustained, long-term processes of engagement with marginalised communities and representatives of the state to enable grassroots leaders of accountability initiatives to develop the capabilities needed to mobilise collective action, shift the terms of interaction with the state and build more equitable health systems.

RESUMO

Background: About 47% of children < 5 years of age are stunted in Guatemala. In this study, the investigators aimed to compare growth and cognitive outcomes between children in second grade that attended five Guatemala City Municipal Nurseries (GCMN) vs. same sex, grade, and age-matched children. Methods: A cross-sectional design nested in a retrospective cohort was implemented between 2015 and 2019. Children that attended the GCMN and matched controls completed a math test and validated receptive language and fluid intelligence tests. The primary caregivers completed a sociodemographic survey. General and generalized linear mixed effect models were used to compare children that attended the GCMN vs. controls. The models were adjusted by maternal education, sex, asset score, and other relevant covariates. Results: Children that attended the GCMN exhibited greater math and fluid intelligence scores relative to the controls in the adjusted models (ß = 6.48; 95% CI (2.35−10.61)) and (ß = 1.20; 95% CI (0.12−2.29)), respectively. Lower odds of stunting were significant for children who went to any early childcare institution (AOR = 0.28; 95% CI (0.09−0.89)). Conclusions: The importance of integrating nutrition and high-quality early childhood education interventions in cognitive and growth outcomes is highlighted in this study. The GCMN model may be a scalable model in similar low-resource settings.

RESUMO

INTRODUCTION: The use of traditional birth attendants (TBAs) in low- and middle-income countries remains controversial. The aim of this secondary analysis was to observe factors associated with visiting a TBA in addition to a skilled nurse for antepartum care and how this additional care was associated with birth characteristics and outcomes. METHODS: The study included a convenience sample of women living in Southwestern Guatemala enrolled in a community nursing program between October 1, 2018, and December 3, 2019. This analysis describes the sociodemographic characteristics, antepartum care, birth outcomes, and postpartum behaviors of women who received antepartum care with skilled nurses only compared with women who received antepartum care with skilled nurses and a TBA. RESULTS: Of the 316 enrollees, 259 had given birth and completed their postpartum visit at the time of analysis. Three women were excluded because of missing data. The majority of women in the study sample reported visiting a TBA over the course of their pregnancies (80.9%). Women who saw a TBA in addition to the nurse were similar to the comparator sample except that they were almost 3 times more likely to have 8 or more prenatal contacts with the nurse. In separate multivariable logistic regression models adjusted for number of prenatal visits, women who saw a TBA in addition to nurses had a reduced likelihood of cesarean birth, increased likelihood of birth with a TBA, and increased likelihood of breastfeeding within one hour of birth compared with women who only received antenatal care from nurses. Patient-reported adverse outcomes were not included in the analysis because of low prevalence and concern about data quality and missing data. DISCUSSION: Among a convenience sample of women in the Trifinio community in rural Guatemala, a large proportion of women continued to seek the care of a TBA in pregnancy while using a skilled nursing program for antenatal care. Intentionally integrating the TBA into the maternity care workforce may be beneficial for improving pregnancy care quality measures.

RESUMO

BACKGROUND: The prevalence of mental health concerns is growing worldwide, along with lack of access to and receipt of needed treatment. Current gaps in treatment provision have led to exploring alternative methods of prevention, with research linking nutrition and mental health, of particular relevance in low- and middle-income countries, with a high prevalence of undernutrition. OBJECTIVES: To examine whether exposure to a protein-energy nutritional supplement during the first 1000 d of life decreased odds of mental distress in adulthood among men and women in Guatemala compared with receiving a low energy-no protein supplement or supplementation outside the 1000-d window. METHODS: Data from participants (n = 1249) in a longitudinal cohort protein-energy supplementation trial (early-life, supplementation data from 1969 to 1977, ages 0-7 y; life course, outcome data from 2017-2018 follow-up, ages 40-57 y) were analyzed for associations between nutrition in the first 1000 d and mental distress in adulthood (WHO Self-Reporting Questionnaire 20 [SRQ-20]), controlling for early-life variables and current life stress; life course variables (e.g. education) were examined as potential mediators of this relation. Generalized linear mixed models and zero-inflated Poisson generalized linear mixed models were utilized. RESULTS: Both partial and full supplementation with Atole during the first 1000 d were associated with 63% (95% CI: 0.16, 0.87) and 56% (95% CI: 0.19, 1.03) lower odds, respectively, of experiencing mental distress in adulthood. Results did not differ by sex. These inverse relations remained relatively unchanged (partial OR = 0.34 [95% CI: 0.14, 0.83]; full OR = 0.38 [95% CI: 0.16, 0.92]) after controlling for early-life and life course variables, including life stress. CONCLUSIONS: Protein-energy supplementation during the first 1000 d of life in Guatemala, where undernutrition is prevalent, may reduce the prevalence of later mental distress in adulthood. This effect appears to occur directly, rather than indirectly, through pathways of life course variables such as education, wealth, and marital status.

RESUMO

Home gardens may help address childhood malnutrition in low- and middle-income countries. In this quasi-experimental pilot study, the Academy of Nutrition and Dietetics, in collaboration with Maya Health Alliance, evaluated the feasibility of augmenting a standard-of-care nutrition-specific package for Maya children with length-for-age z score ≤-2 (stunting) in rural Guatemala with a nutrition-sensitive home garden intervention. Two agrarian municipalities in Guatemala were included. Families of 70 children with stunting from 1 municipality received the standard-of-care package (food supplementation, multiple micronutrient powders, monthly nutrition home visits, group nutrition classes). Families of 70 children with stunting from another municipality received the standard-of-care package plus a home garden intervention (garden materials, monthly agricultural home visits, agriculture classes). Maternal and child dietary diversity, household food insecurity, child growth, and agricultural indicators were collected at baseline and 6 months later and were analyzed using mixed linear and logistic regression models. Compared with the standard-of-care group, the garden intervention group had improved child (odds ratio [OR] 3.66, 95% CI 0.89-15.10, P = 0.07) and maternal dietary diversity (OR 2.31, 95% CI 0.80-6.65, P = 0.12) and decreased food insecurity (OR 0.38, 95% CI 0.11-1.35, P = 0.14); however, these effects were not statistically significant. Participation in gardens predicted a higher length-for-age z-score (change difference [CD] 0.22 SD, 95% CI 0.05-0.38, P = 0.009), greater crop species count (CD 2.97 crops, 95% CI 1.79-4.16, P < 0.001), and greater nutritional functional diversity (CD 0.04 points, 95% CI 0.01-0.07, P = 0.006) than standard-of-care alone. Home garden interventions are feasible in rural Guatemala and may have potential benefits for child growth when added to other nutrition-specific interventions.

RESUMO

Adequate nutrition during the complementary feeding period is critical for optimal child growth and development and for promoting long-term educational attainment and economic potential. To prioritize limited public health resources, there is a need for studies that rigorously assess the influence of multicomponent integrated nutrition interventions in children younger than age 2 years in different contexts. This study aimed to describe the rationale and protocol for the Saqmolo' Project using the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines. The Saqmolo' (ie, "egg" in the Mayan language, Kaqchiquel) Project is an individually randomized, partially blinded, controlled comparative effectiveness trial to evaluate the influence of adding delivery of a single whole egg per day to local standard nutrition care (ie, growth monitoring, medical care, deworming medication, multiple micronutrient powders for point-of-use food fortification [chispitas], and individualized complementary and responsive feeding education for caregivers) for 6 months, compared with the local standard nutrition care package alone, on child development, growth, and diet quality measures in rural indigenous Mayan infants aged 6 to 9 months at baseline (N = 1,200). The study is being executed in partnership with the Wuqu' Kawoq/Maya Health Alliance, a primary health care organization located in central Guatemala. Primary outcomes for this study are changes in global development scores, assessed using the Guide for Monitoring Global Development and the Caregiver Reported Child Development Instruments. Secondary outcomes include changes in infant hemoglobin, anthropometric measures (including z scores for weight for age, length for age, weight for length, and head circumference for age), and diet quality as measured using the World Health Organization's infant and young child feeding indicators. The results of the Saqmolo' Project may help to inform public health decision making regarding resource allocation for effective nutrition interventions during the complementary feeding period.

RESUMO

En Guatemala, la producción del cultivo de papa se ve afectada por los nematodos Globodera rostochiensis y Globo-dera pallida. La capacidad de ambas especies para formar quistes complica su control y provoca el aumento de sus poblaciones. En Guatemala se reporta la presencia de ambas especies de nematodos por identificación morfológica, sin embargo, no se ha realizado una confirmación molecular. Este es el primer estudio para validar la presencia de ambas especies de nematodos por PCR múltiple y la determinación de la diversidad y estructura genética de las poblaciones utilizando marcadores moleculares. Se realizaron muestreos en cuatro departamentos productores de papa del país. La identificación por PCR se realizó con el cebador común ITS5 y los cebadores PITSr3 específico para G. rostochiensisy PITSp4 para G. pallida. La caracterización molecular se realizó con el marcador AFLP. Se confirmó la presencia de las dos especies de nematodos en los cuatro departamentos. Los índices de diversidad Shannon y heterocigosidad esperada revelaron mayor diversidad genética en G. rostochiensis (H = 0.311, He = 0.301) que en G. pallida (H = 0.035, He = 0.223). Los métodos NJ, DAPC y PCA exhibieron una débil estructura entre las poblaciones de ambas especies de nematodos. Los resultados sugieren un patrón de dispersión desde Quetzaltenango hacia el resto del país, atribuido a la comercialización de semilla contaminada con nematodos. Se sugiere promover programas de socialización sobre los beneficios del uso de semilla certificada, además de constantes monitoreos moleculares para un diagnóstico certero de ambas especies de nematodos.


In Guatemala, potato crop production is affected by the nematodes Globodera rostochiensis and Globodera pallida. The ability of both species to form cysts complicates their control and causes an increase in their populations. In Guatemala, both species of nematodes have been reported by morphological identification; however, molecular confirmation has not been carried out. It is the first study to validate the presence of both nematode species by multiplex PCR and determine the diversity and genetic structure of the populations using molecular markers. Sampling was carried out in four pota-to-producing departments of the country. PCR identification was performed with the common primer ITS5 and the primers PITSr3 specific for G. rostochiensis and PITSp4 for G. pallida. We performed molecular characterization with the AFLP marker. We confirmed the presence of the two nematode species in the four departments. Shannon diversity and expected heterozygosity indices revealed higher genetic diversity in G. rostochiensis (H = 0.311, He = 0.301) than in G. pallida (H = 0.035, He = 0.223). The NJ, DAPC, and PCA methods exhibited weak structure among populations of both nematode species. The results suggest a dispersal pattern from Quetzaltenango to the rest of the country, attributed to the commer-cialization of seed contaminated with nematodes. We suggest promoting socialization programs on the benefits of using certified seeds and constant molecular monitoring for an accurate diagnosis of both species of nematodes.

RESUMO

There are few scientific studies that explore the use of medicinal plants for snakebite envenoming in Central America, although plant-based therapies have been traditionally used in the region. This work reviews the studies conducted in Central America to assess the ability of extracts obtained from plants of local ethnomedical use to inhibit toxic activities of the venom of Bothrops asper, the snake responsible for approximately half of the snakebite envenomings in these countries. The search prioritized the description of the plants used in Guatemala, since most of the studies described in this work were conducted in that country, although references to other countries are included. Information concerning secondary metabolites and other pharmacological activities of these plant species, relevant to the treatment of snakebites, was also described. The literature search was conducted in the Google Scholar, PubMed and Scopus databases and completed with locally available literature. It was found that extracts of 12 plant species inhibited the hemorrhagic effect of the venom and three neutralized the edema-forming activity, while inhibition of proteolytic and phospholipase A2 (PLA2) activities was achieved by three and one plant species, respectively. Only Brownea rosa-de-monte was able to effectively counteract the in vitro coagulant effect of the venom. Some plant extracts screened in Guatemala demonstrated procoagulant or anti-thrombin intrinsic effects that might aggravate the coagulopathy induced by the venom. These findings underscore the need of carrying out scientific studies aimed to validate the inhibitory potential of Central American plant extracts and their metabolites against B. asper venom.


Pocos estudios científicos han explorado el uso de plantas medicinales para el tratamiento del envenenamiento ofídico en Centroamérica, a pesar de que las terapias basadas en plantas son de uso tradicional en la región. Este trabajo recopiló información sobre los estudios realizados en Centroamérica para evaluar la capacidad de extractos de plantas de uso etno-médico para inhibir las actividades tóxicas del veneno de Bothrops asper, la serpiente responsable de aproximadamente la mitad de los envenenamientos ofídicos en Centroamérica. La búsqueda priorizó la descripción de plantas utilizadas en Gua-temala, ya que la mayoría de los estudios aquí descritos fueron realizados en ese país. También se incluyó la descripción de los metabolitos secundarios y otras actividades farmacológicas de las especies evaluadas, que podrían explicar su uso como antiofídicos. La búsqueda de literatura se realizó en las bases de datos de Google Scholar, PubMed, Scopus, y se completó con literatura disponible localmente. Se determinó que 12 extractos de plantas inhibieron el efecto hemorrágico del veneno y tres el efecto edematígeno; la actividad proteolítica fue inhibida por extractos de tres especies y la fosfolipasa A2 (PLA2) por una especie. Solamente Brownea rosa-de-monte demostró inhibir efectivamente el efecto coagulante del veneno in vitro. Algunos extractos de las plantas tamizadas en Guatemala demostraron efectos procoagulantes o anti-trombina intrínsecos, que podrían agravar las alteraciones inducidas por el veneno en la coagulación. Estos hallazgos enfatizan la necesidad de validar el potencial de extractos de plantas centroamericanas y sus metabolitos secundarios para neutralizar el veneno de B. asper.

RESUMO

OBJECTIVE: The majority of indigenous Guatemalan women give birth at home with traditional birth attendants (TBAs), and maternal mortality rates are high (Ministerio de Salud, 2017). Our objective was to better understand decision-making around whether to remain in the home or to seek facility-level care for obstetric complications. METHODS: This study was a qualitative analysis using semi-structured interviews in a Maya population in the Western Highlands of Guatemala who received prenatal care between April 2017 and December 2018. We used qualitative interviews with women who were identified as medically high-risk and needing facility-level care, offered assistance with acquiring such care, and yet declined this option. Women interviewed were connected to a primary care organization called Maya Health Alliance, through care with TBAs involved in a program utilizing a smartphone-based decision support application to identify maternal and neonatal complications of pregnancy. Interviews were analyzed using Dedoose (www.dedoose.com). Deductive and inductive analysis was performed. RESULTS: Barriers to care included a disagreement between the respondent and TBA about indications for facility care, fear of hospital care, concerns about the quality of hospital care, logistical obstacles, and lack of control; and they were more often described by respondents who had previous healthcare experiences. Therapeutic misalignment occurred more with conditions perceived to be less severe. Participants described a balancing of fears and apprehensions against concerns of low quality and disrespectful maternity care, and in the setting of emergent conditions, disregarded barriers that were often described as inhibiting non-urgent obstetric care. CONCLUSIONS: The decision to engage in medical care in this population of Maya women involves a weighing of the perception of seriousness of the medical complication against fears of facility level care and concerns of a poor quality of care.

RESUMO

BACKGROUND: Global disparities in maternal mortality could be reduced by universal facility delivery. Yet, deficiencies in the quality of care prevent some mothers from seeking facility-based obstetric care. Obstetric care navigators (OCNs) are a new form of lay health workers that combine elements of continuous labor support and care navigation to promote obstetric referrals. Here we report qualitative results from the pilot OCN project implemented in Indigenous villages in the Guatemalan central highlands. METHODS: We conducted semi-structured interviews with 17 mothers who received OCN accompaniment and 13 staff-namely physicians, nurses, and social workers-of the main public hospital in the pilot's catchment area (Chimaltenango). Interviews queried OCN's impact on patient and hospital staff experience and understanding of intended OCN roles. Audiorecorded interviews were transcribed, coded, and underwent content analysis. RESULTS: Maternal fear of surgical intervention, disrespectful and abusive treatment, and linguistic barriers were principal deterrents of care seeking. Physicians and nurses reported cultural barriers, opposition from family, and inadequate hospital resources as challenges to providing care to Indigenous mothers. Patient and hospital staff identified four valuable services offered by OCNs: emotional support, patient advocacy, facilitation of patient-provider communication, and care coordination. While patients and most physicians felt that OCNs had an overwhelmingly positive impact, nurses felt their effort would be better directed toward traditional nursing tasks. CONCLUSIONS: Many barriers to maternity care exist for Indigenous mothers in Guatemala. OCNs can improve mothers' experiences in public hospitals and reduce limitations faced by providers. However, broader buy-in from hospital staff-especially nurses-appears critical to program success. Future research should focus on measuring the impact of obstetric care navigation on key clinical outcomes (cesarean delivery) and mothers' future care seeking behavior.

RESUMO

BACKGROUND: Cutaneous leishmaniasis (CL), endemic in Guatemala, mostly affects poor people living in the northern region. A national control program that includes surveillance, diagnose, and treatment offered free of cost by the Ministry of Health (MoH) has been in place since 2003. However, the incidence is increasing and treatment rates are not optimal, suggesting that current efforts are not being effective. This study aimed to understand barriers and facilitators of CL control in Guatemala as experienced and perceived by key stakeholders in order to comprehend what works well and does not and suggest evidence-informed interventions. METHODS: The study was conducted in the Cobán municipality, the most endemic of Guatemala, situated in the Department of Alta Verapaz. Data were collected during May and June 2019 via focus groups and semi-structured interviews with key stakeholders, including local and national health personnel and residents of four communities of the endemic region. Thematic and content analysis of the collected data was conducted using NVIVO. RESULTS: Three overarching issues hamper the effectiveness of current CL efforts: resource scarcity, treatment challenges, and knowledge-action gaps. Scarce economic resources from the MoH and community residents negatively impact incidence, detection of cases and treatment rates in that preventive action is insufficient and healthcare access is low. In addition, local health workers often lack specialized CL training and access to the national CL control guidelines. With regards to the population living in the study area, misunderstanding of disease causation, shame associated with CL lesions, treatment pain fear, and long (often uncertain) waiting times for diagnose and treatment negatively affect people's willingness to seek help, treatment adherence, and their trust on the healthcare provided. CONCLUSIONS: Culturally sensitive CL preventive action must be developed. Given the scarce economic resources available for CL control in the country, the involvement of trained community health workers and the inclusion of thermotherapy as a treatment option is also advised. Other cost-effective actions include: ensuring all health workers receive CL training and have access to national CL control guidelines, improving national procurement system to avoid treatment shortages, and provision of motorized vehicles to increase active surveillance and treatment rates.

RESUMO

The present study examined the chemical composition and antimicrobial and gastrointestinal activity of the essential oils of Elettaria cardamomum (L.) Maton harvested in India (EC-I) and Guatemala (EC-G). Monoterpenes were present in higher concentration in EC-I (83.24%) than in EC-G (73.03%), whereas sesquiterpenes were present in a higher concentration in EC-G (18.35%) than in EC-I (9.27%). Minimum inhibitory concentrations (MICs) of 0.5 and 0.25 mg/mL were demonstrated against Pseudomonas aeruginosa in EC-G and EC-I, respectively, whereas MICs of 1 and 0.5 mg/mL were demonstrated against Escherichia coli in EC-G and EC-I, respectively. The treatment with control had the highest kill-time potential, whereas the treatment with oils had shorter kill-time. EC-I was observed to be more potent in the castor oil-induced diarrhea model than EC-G. At 100 and 200 mg/kg, P.O., EC-I exhibited 40% and 80% protection, respectively, and EC-G exhibited 20% and 60% protection, respectively, in mice, whereas loperamide (10 mg/kg, i.p., positive control) exhibited 100% protection. In the in vitro experiments, EC-I inhibited both carbachol (CCh, 1 µM) and high K+ (80 mM)-induced contractions at significantly lower concentrations than EC-G. Thus, EC-I significantly inhibited P. aeruginosa and E. coli and exhibited more potent antidiarrheal and antispasmodic effects than EC-G.

RESUMO

BACKGROUND: Household air pollution adversely affects human health and the environment, yet more than 40% of the world still depends on solid cooking fuels. The House Air Pollution Intervention Network (HAPIN) randomized controlled trial is assessing the health effects of a liquefied petroleum gas (LPG) stove and 18-month supply of free fuel in 3,200 households in rural Guatemala, India, Peru, and Rwanda. AIMS: We conducted formative research in Guatemala to create visual messages that support the sustained, exclusive use of LPG in HAPIN intervention households. METHOD: We conducted ethnographic research, including direct observation (n = 36), in-depth (n = 18), and semistructured (n = 6) interviews, and 24 focus group discussions (n = 96) to understand participants' experience with LPG. Sixty participants were selected from a pilot study of LPG stove and 2-months of free fuel to assess the acceptability and use of LPG. Emergent themes were used to create visual messages based on observations and interviews in 40 households; messages were tested and revised in focus group discussions with 20 households. RESULTS: We identified 50 codes related to household air pollution and stoves; these were reduced into 24 themes relevant to LPG stoves, prioritizing 12 for calendars. Messages addressed fear and reluctance to use LPG; preference of wood stoves for cooking traditional foods; sustainability and accessibility of fuel; association between health outcomes and household air pollution; and the need for inspirational and aspirational messages. DISCUSSION: We created a flip chart and calendar illustrating themes to promote exclusive LPG use in HAPIN intervention households.
