Background: Community health worker (CHW) programmes are a valuable component of primary care in resource-poor settings. The evidence supporting their effectiveness generally shows improvements in disease-specific outcomes relative to the absence of a CHW programme. In this study, we evaluated expan...ding an existing HIV and tuberculosis (TB) disease-specific CHW programme into a polyvalent, household-based model that subsequently included non-communicable diseases (NCDs), malnutrition and TB screening, as well as family planning and antenatal care (ANC).
Methods: We conducted a stepped-wedge cluster randomised controlled trial in Neno District, Malawi. Six clusters of approximately 20 000 residents were formed from the catchment areas of 11 healthcare facilities. The intervention roll-out was staggered every 3 months over 18 months, with CHWs receiving a 5-day foundational training for their new tasks and assigned 20–40 households for monthly (or more frequent) visits.
Findings: The intervention resulted in a decrease of approximately 20% in the rate of patients defaulting from chronic NCD care each month (−0.8 percentage points (pp) (95% credible interval: −2.5 to 0.5)) while maintaining the already low default rates for HIV patients (0.0 pp, 95% CI: −0.6 to 0.5). First trimester ANC attendance increased by approximately 30% (6.5pp (−0.3, 15.8)) and paediatric malnutrition case finding declined by 10% (−0.6 per 1000 (95% CI −2.5 to 0.8)). There were no changes in TB programme outcomes, potentially due to data challenges.

Transmission of many infectious diseases depends on interactions between humans, animals, and the environment. Incorporating these complex processes in transmission dynamic models can help inform policy and disease control int...erventions. We identified 20 diseases involving environmentally persistent pathogens (ie, pathogens that survive for more than 48 h in the environment and can cause subsequent human infections), of which indirect transmission can occur from animals to humans via the environment.

Cet article documente le processus de mise en œuvre du Traitement préventif intermittent TPI), une stratégie de prévention du paludisme dont l’administration est couplée au Programme élargi de vaccination (PEV) dans les services de santé, les réactions des prestat...aires, des populations et leurs facteurs explicatifs. Les résultats montrent que l’absence de connaissances adéquates à propos du TPI n’a pas empêché son appropriation par les communautés, dans la mesure où les perceptions lui accordent une valeur pratique et l’intègrent dans les besoins ressentis. C’est pourquoi les enfants ont reçu, dans la grande majorité, les médicaments administrés. Certains comportements en décalage s’expliquent plus par des contraintes, des insuffisances du système de santé et de vaccination que par un refus. Chez les prestataires de soins, l’information a été plus disponible du côté les infirmiers étatiques. Cependant, les processus de détournement et les attitudes d’indifférence étaient plus visibles chez ces derniers.

Objetivos.
Estimar la carga de tuberculosis (TB) en menores de 15 años y describir las características clínico, epidemiológicas y los resultados del tratamiento antituberculoso en Ecuador.
Métodos.
Se realizó un estudio retrospectivo utilizando los datos del programa nacional de TB de los... años 2015 y 2016. Se estimaron la tasa y el porcentaje de casos de TB infantil y se describieron las características de la enfermedad y el resultado del tratamiento según las categorías de edad: 0-4, 5-9 y 10-14 años.
Resultados.
De los 10 991 casos de TB diagnosticados, 223 (2,03%) fueron menores de 15 años; según la región del país esta carga varió entre 0 y 5,5%. De los 223 casos, en 213 se había registrado el resultado del tratamiento y fueron incluidos en el estudio; 78 (37%) eran menores de 5 años y en 147 (69%) no hubo registro de la investigación de contactos. Sesenta y cinco (68%) de los adolescentes y 40 (51%) de los menores de 5 años tenían diagnóstico de TB pulmonar. La prevalencia de VIH fue 11,5% en los menores 5 años y 6,3% en el grupo de 10-14 años. El tratamiento fue satisfactorio en el 93% de los casos, (curación, 36,6%, tratamiento terminado, 56,8%).
Conclusiones:
Ecuador presenta un alto porcentaje de subdiagnóstico de TB infantil y una carga menor a la esperada, principalmente en menores de 5 años. La alta prevalencia de VIH y la falta de sistematización adecuada de la investigación de contactos en los adolescentes revelan la necesidad de considerar estrategias centradas en la familia y que involucren la capacitación del personal de salud en el manejo del paciente pediátrico centrándose en las necesidades específicas de cada población.

Abstract: Posttraumatic stress disorder (PTSD) is a chronic psychological disorder that can develop after exposure to a traumatic event. This review summarizes the literature on the epidemiology, assessment, and treatment of PTSD. We provide a review of the characteristics of PTSD along with associa...ted risk factors, and describe brief, evidence-based measures that can be used to screen for PTSD and monitor symptom changes over time. In regard to treatment, we highlight commonly used, evidence-based psychotherapies and pharmacotherapies for PTSD. Among psychotherapeutic approaches, evidence-based approaches include cognitive-behavioral therapies (e.g., Prolonged Exposure and Cognitive Processing Therapy) and Eye Movement Desensitization and Reprocessing. A wide variety of pharmacotherapies have received some level of research support for PTSD symptom alleviation, although selective serotonin reuptake inhibitors have the largest evidence base to date.

Several diagnostic criteria of Post-traumatic Stress Disorder (PTSD) are remarkably similar to symptoms reported by individuals with depression, particularly as they manifest as cognitive processing deficits in children. Because of this overlap in profile and the high rate of comorbidity of PTSD and... depression (48% to 69%), pinpointing similarities/differences in cognitive processes related to each of these disorders is essential to accurate diagnosis. This study aims to examine cognitive performance profiles of 23 children who have been victims of PTSD and to compare their results with 23 children with depression and 24 controls.

Approximately 80% of the 463 million adults worldwide with diabetes live in low-income and middle-income countries (LMICs). A major obstacle to designing evidence-based policies to improve diabetes outcomes in LMICs is the scarce availability of nationally representative data on the current patterns... of treatment coverage. The objectives of this study were to estimate the proportion of adults with diabetes in LMICs who receive coverage of recommended pharmacological and non-pharmacological diabetes treatment; and to describe country-level and individual-level characteristics that are associated with treatment.

Background: Community Health Workers (CHWs) have a positive impact on the provision of community-based
primary health care through screening, treatment, referral, psychosocial support, and accompaniment. With a
broad scope of work, CHW programs must balance the breadth and depth of tasks to mainta...in CHW motivation for
high-quality care delivery. Few studies have described the CHW perspective on intrinsic and extrinsic motivation to
enhance their programmatic activities.
Methods: We utilized an exploratory qualitative study design with CHWs employed in the household model in Neno
District, Malawi, to explore their perspectives on intrinsic and extrinsic motivators and dissatisfiers in their work. Data
was collected in 8 focus group discussions with 90 CHWs in October 2018 and March–April 2019 in seven purposively
selected catchment areas. All interviews were audiotaped, transcribed verbatim, coded, and analyzed using Dedoose.
Results: Themes of complex intrinsic and extrinsic factors were generated from the perspectives of the CHWs in
the focus group discussions. Study results indicate that enabling factors are primarily intrinsic factors such as positive
patient outcomes, community respect, and recognition by the formal health care system but can lead to the chal-
lenge of increased scope and workload. Extrinsic factors can provide challenges, including an increased scope and
workload from original expectations, lack of resources to utilize in their work, and rugged geography. However, a posi-
tive work environment through supportive relationships between CHWs and supervisors enables the CHWs.
Conclusion: This study demonstrated enabling factors and challenges for CHW performance from their perspec-
tive within the dual-factor theory. We can mitigate challenges through focused efforts to limit geographical distance,
manage workload, and strengthen CHW support to reinforce their recognition and trust. Such programmatic empha-
sis can focus on enhancing motivational factors found in this study to improve the CHWs’ experience in their role. The
engagement of CHWs, the communities, and the formal health care system is critical to improving the care provided
to the patients and communities, along with building supportive systems to recognize the work done by CHWs for
the primary health care systems.

Leishmaniases are a group of diseases of zoonotic importance caused by over 20 species of protozoa of the genus Leishmania, in which domestic dogs are considered to be the main reservoir for the disease. However, the involvement of other vertebrates as reservoirs for these parasites has also been in...vestigated. Therefore, the objective of the present study was to carry out a systematic review with meta-analysis on occurrences of leishmaniasis in equids. The case reports described animals with cutaneous symptoms of leishmaniasis (papules, nodules, ulcers or crusts) that regressed spontaneously, located mainly on the head and limbs, from which three species of protozoa were identified in the lesions: Leishmania braziliensis, Leishmania infantum and Leishmania siamensis. In turn, the meta-analysis showed a combined prevalence of 25%, although with high heterogeneity among the studies, which was attributed to the use of different methods for diagnosing the disease. Leishmaniasis in equids is a benign disease but it should be included in the differential diagnosis of cutaneous diseases among these species. Seroepidemiological studies are important in investigating and monitoring suspected exposure of these hosts to the parasite, especially in endemic areas. However, there is also a need to standardize diagnostic methods.

In 2012, all Member States of the World Health Organization (WHO) endorsed a historical target to reduce premature mortality from noncommunicable diseases
(NCD). This commitment was echoed in 2015 by the United Nations Sustainable Development Goals, which included a target to reduce premature morta...lity (the
measure of unfulfilled life expectancy and deaths between the ages of 30 and 70 years) from NCD by 30% by the year 2030. The Sustainable Development Goals are especially relevant to cardiovascular disease (CVD), the leading cause of death globally, with increasing prevalence in low- and middle-income countries (LMIC).
