RESUMO
Chronic kidney disease (CKD) has severe consequences on the quality and expectancy of life and is considered a major health problem worldwide. This is, especially relevant in pediatric patients, as they have unique characteristics and a mortality rate 30 times higher (in advanced stages) than healthy people. This review aims to define the minimum components for the diagnostic approach and monitoring of CKD in the pediatric population from primary health care to promote comprehensive care and adequate risk management. For this purpose, we performed a systematic review of the literature with a panel of experts. Based on the evidence, to optimize the definition, diagnosis, and timely treatment of CKD in the pediatric population, we formulated 21 recommendations. These were approved by the research team and peer-reviewed by clinical experts. They will facilitate the definition of the diagnostic approach for CKD in the pediatric population in primary health-care settings, allowing for timely treatment intervention, comprehensive care, and monitoring of this disease.

RESUMO
The immune response is central to the pathogenesis of cutaneous leishmaniasis (CL). However, most of our current understanding of the immune response in human CL derives from the analysis of systemic responses, which only partially reflect what occurs in the skin. In this study, we characterized the transcriptional dynamics of skin lesions during the course of treatment of CL patients and identified gene signatures and pathways associated with healing and nonhealing responses. We performed a comparative transcriptome profiling of serial skin lesion biopsies obtained before, in the middle, and at the end of treatment of CL patients (eight who were cured and eight with treatment failure). Lesion transcriptomes from patients who healed revealed recovery of the stratum corneum, suppression of the T cell-mediated inflammatory response, and damping of neutrophil activation, as early as 10 d after initiation of treatment. These transcriptional programs of healing were consolidated before lesion re-epithelization. In stark contrast, downregulation of genes involved in keratinization was observed throughout treatment in patients who did not heal, indicating that in addition to uncontrolled inflammation, treatment failure of CL is mediated by impaired mechanisms of wound healing. This work provides insights into the factors that contribute to the effective resolution of skin lesions caused by Leishmania (Viannia) species, sheds light on the consolidation of transcriptional programs of healing and nonhealing responses before the clinically apparent resolution of skin lesions, and identifies inflammatory and wound healing targets for host-directed therapies for CL.

Introduction: Prostate cancer is more prevalent in men. The disease and treatment generate urinary, intestinal, sexual, hormonal and emotional symptoms that impact the functional performance of men who suffer from them. Self-management of symptoms has been considered since the World Health Organization (WHO) as a strategy to allow men to better understand their disease and generate skills to manage it from a home environment. Objective: Determine the effectiveness of the Prostactive Intervention for the selfmanagement of symptoms and its impact on functional performance, in people with prostate cancer undergoing treatment who attend the Oncology Unit of the Nogales Clinic between 2022 and 2023. Materials and methods: It is a parallel experimental design determined by the random formation of two groups with a sample size of 100 participants, 50 for the control (CG) who will receive the usual care and 50 for the experimental (GI) to which the Prostactive intervention was implemented, which It consists of 4 face-to-face sessions in which you will be explained how to manage the symptoms you present due to prostate cancer and the treatment. Subsequently, telephone follow-up was carried out to determine the health status at week 8 after the face-to-face sessions. Results: the Prostactive Intervention improved the levels of self-efficacy in the IG participants, functional performance (0.0001) in addition to the self-management of urinary symptoms with statistically significant differences compared to the CG. No changes were identified in obstructive symptoms (P value= 0.6), sexual symptoms, and hormonal symptoms. Conclusion: The Prostactive Intervention improves symptom self-management in men with CP undergoing treatment, in addition to self-efficacy and Functional Performance. (AU)

Traditionally, the initiation of enteral nutrition after a percutaneous endoscopic gastrostomy (PEG) is performed between 12 and 24 hours. Different research suggests that early initiation might be a safe option. Our aim was to determine whether starting enteral nutrition 4 hours after performing PEG is a safe practice in terms of risk of intolerance, complications, or death, compared to starting it at 12 hours. We carried out a prospective, randomized, multicenter study in third and fourth level institutions in Bogotá and Cundinamarca, between June 2020 and May 2022, 117 patients were included who were randomized into 2 groups, group A with early nutrition initiation (4 hours), and standard group B (12 hours). The most frequent mechanism of dysphagia was cerebrovascular disease (43%), followed by complications of COVID19 infection (26%). There were no statistically significant differences between the groups evaluated regarding the percentage of intolerance to nutrition, RR = 0.93 (CI 0.30-2.90), there were also no differences in terms of postoperative complications, (RR) = 0.34 (CI 0.09-1.16), and no differences were found in mortality between the evaluated groups, (RR) = 1.12 (CI 0.59-2.15). In conclusion, early initiation of nutrition through the gastrostomy, 4 hours after performing the PEG, is a safe behavior that is not related to greater intolerance to nutrition, complications, or death, compared to later initiation.

Background: People living with HIV (PLWHIV) are at a higher risk of developing coronary artery disease (CAD). We aimed to assess the factors associated with CAD among PLWHIV in Colombia. Methods: We conducted a retrospective cohort study based on adults newly diagnosed with HIV, reported to the Colombian HIV/AIDS registry from 2018 to 2021. Baseline demographic and clinical characteristics were compared by age (<50 and ≥ 50 years). Our main outcome was the presence of CAD. Logistic regression models were used to assess the association between traditional and HIV-related factors with CAD. These associations were also evaluated in stratified models by age. Effect measures were odds ratios (OR) and their 95% confidence intervals. Results: Among 36,483 PLWHIV, the frequency of CAD was 0.53% (n = 196). There was a high prevalence of impaired fasting glucose/diabetes mellitus (12.62%), overweight/obesity (27.79%), elevated LDL-c (86.69%), and hypertriglyceridemia (72.76%). Factors associated with CAD included male gender (OR: 2.01, 95% CI: 1.12-3.58), age ≥50 years (OR: 4.96, 95% CI: 3.29-7.45), lipoatrophy or lipodystrophy (OR 5.12, 95% CI: 1.12-23.33), AIDS-defining conditions (OR: 1.83, 95% CI: 1.07-3.12), obesity (OR: 2.95, 95% CI: 1.69-5.10), diabetes mellitus (OR: 2.50, 95% CI: 1.25-4.97), and renal impairment (OR: 3.15, 95% CI: 1.83-5.42). Conclusions: Traditional CAD risk factors are common in PLWHIV. There were traditional and disease-specific factors associated with increased odds of CAD. These findings may aid clinicians and decision-makers in reducing the impact of CAD in PLWHIV.
RESUMO
INTRODUCTION: We compared the association of glomerular filtration rate (GFR) estimated with the Cockcroft-Gault, Modification of Diet in Renal Disease study (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), or the new CKD-EPI without race (CKD-EPI-NR) equations, with 4-year all-cause mortality in patients with diabetes. RESEARCH DESIGN AND METHODS: We analyzed a nationwide, centralized database of all adults diagnosed with diabetes assisted by the Colombian Health System between July 1, 2015, and June 30, 2019. Plasma creatinine was used to calculate baseline estimated glomerular filtration rate (eGFR) and classify each patient in a chronic kidney disease (CKD) stage, by each of the four equations. We used multivariate logistic regression to compare the association between CKD stage and mortality, and receiver operating characteristic (ROC) analyses to assess the overall association of eGFR by each equation and mortality. RESULTS: The study included 758,219 patients (58% female, 7.2% black race, mean age 62.3, Glycated hemoglobin A1c [HbA1c] 7.4%). There were 35,296 deaths over the study follow-up. Considering eGFR by each equation as a continuous variable, the odds of death decreased by 1.1%-1.5% for each additional mL/min. Compared with CKD stage 1 of each equation, being placed in CKD stages 3a, 3b, or 4 by MDRD or CKD-EPI-NR was associated with greater odds of death than being categorized in the same stages by CKD-EPI. Among patients of black race, the adjusted OR of mortality for CKD stage 4 relative to stage 1 was 4.63 (95% CI 3.39 to 6.35) for MDRD, 3.66 (2.85 to 4.69) for CKD-EPI-NR, 3.01 (2.38 to 3.81) for CKD-EPI, and 2.82 (2.29 to 3.49) for Cockcroft-Gault. The area under the ROC curve to discriminate by survival status was greatest for MDRD, followed by CKD-EPI-NR, CKD-EPI, and Cockcroft-Gault, in that order (p<0.001 for all differences). CONCLUSIONS: Compared with other eGFR equations, MDRD showed the strongest association with all-cause mortality in a sample of Latin-American patients with diabetes. This difference was most pronounced among patients of black race.

Tradicionalmente, el inicio de nutrición enteral, luego de una gastrostomía endoscópica percutánea (GEP) se realiza entre 12 a 24 horas. Diferentes investigaciones sugieren que iniciarla más temprano podría ser una opción segura. El objetivo es determinar si el inicio de nutrición enteral a las 4 horas después de realizar GEP es una conducta segura en cuanto al riesgo de intolerancia, complicaciones o muerte, comparado con iniciarla a las 12 horas. Realizamos un estudio prospectivo, aleatorizado, multicéntrico en instituciones de tercer y cuarto nivel de Bogotá y Cundinamarca, entre junio de 2020 y mayo de 2022, se incluyeron 117 pacientes que fueron aleatorizados en 2 grupos, el grupo A de inicio temprano de nutrición (4 horas), y el grupo B de inicio estándar (12 horas). El mecanismo más frecuente de disfagia fue la enfermedad cerebrovascular (43%), seguido por complicaciones de infección por COVID-19 (26%). No hubo diferencias estadísticamente significativas entre los grupos evaluados respecto al porcentaje de intolerancia a la nutrición, RR = 0,93 (IC 0,30-2,90), tampoco hubo diferencias en términos de complicaciones posoperatorias, (RR) = 0,34 (IC 0,09-1,16), y no se encontraron diferencias en la mortalidad entre los grupos evaluados, (RR) = 1,12 (IC 0,59 - 2,15). En conclusión, el inicio de nutrición a través de la gastrostomía de forma temprana, 4 horas después de la realización de la GEP es una conducta segura que no se relaciona con una mayor intolerancia a la nutrición, complicaciones o muerte, en comparación con un inicio más tardío.

RESUMO
Objective: The magnitude of the mortality benefit conferred by good integral metabolic control in diabetes in not sufficiently known, especially among Latin American patients. We prospectively studied the association between sustained control of blood glucose (HbA1c<7%), systolic blood pressure (SBP) (<130 mmHg) and LDL (LDLc, <100mg/dL) and non-HDL (non-HDLc, <130 mg/dL) cholesterol, and death from any cause among all adult patients with diagnosed diabetes in Colombia. Methods: We retrospectively analyzed data from a nationwide, centralized, mandatory registry of all patients with diagnosed diabetes assisted by the Colombian health system between July 1, 2015, and June 30, 2019. We estimated the associations of sustained achievement of each goal, and of the joint triple goal (HbA1c + SBP + LDLc) with all-cause death. Associations were assessed after adjustment for sex, age, race, insurance type and BMI in multivariable logistic models. Results: We studied 1 352 846 people with diabetes. Sustained SBP (OR 0.42 [0.41-0.43]), HbA1c (OR 0.25 [0.24-0.26]) and LDLc (OR 0.28 [0.27-0.29]) control had strong negative associations with death. Moreover, among the 5.4% of participants who achieved joint, sustained metabolic control, the OR for death was 0.19 (0.18-0.21). Importantly, the impact of sustained, joint metabolic control was significantly smaller for patients of black race compared to other races (OR 0.31 [0.23-0.43] versus 0.18 [0.17-0.20], p-value for interaction <0.001), mostly at the expense of a smaller impact of LDLc control. The results were similar across body-mass index categories. Conclusions: Sustained and simultaneous metabolic control was associated with remarkably lower odds of death.

Context: The relative importance of the control of different metabolic risk factors for the prevention of chronic kidney disease among patients with diabetes in real life conditions is insufficiently understood. Objective: We evaluated the effect of the achievement of glycated hemoglobin A1c (HbA1c), systolic blood pressure (SBP), and low-density lipoprotein cholesterol (LDLc) or non-high-density lipoprotein cholesterol (non-HDLc) goals (ABC goals) on the development of incident chronic kidney disease (iCKD) among patients with diabetes. Methods: In a nationwide registry of all individuals diagnosed with diabetes assisted by the health system in Colombia, we analyzed the association between baseline or sustained goal achievement and development of iCKD over a 4-year follow-up. iCKD was defined as a new occurrence of an estimated glomerular filtration rate less than 60â mL/min/1.73â m2, hemodialysis, peritoneal dialysis, or kidney transplant. Results: The study included 998 790 adults with diabetes (56% female, mean age 59). There were 125 626 cases of iCKD. After adjustment for multiple confounders, a baseline SBP less than 130â mm Hg (odds ratio [OR] 0.79 [0.78-0.80]) and a baseline HbA1c less than 7.0% (OR 0.86 [0.85-0.87]) were negatively associated with iCKD. Sustained achievement showed stronger negative associations with iCKD than just baseline achievement. Considering each goal separately, sustained non-HDLc less than 130â mg/dL had the strongest negative association with iCKD (OR 0.67 [0.65-0.69]). Patients who maintained the triple ABC goal over the entire follow-up had 32% (29-34) lower odds of developing CKD, 38% (34-42) if they additionally kept a normal body mass index (BMI). Sustained ABC control including a normal BMI was more strongly associated with a lower incidence of CKD in patients of Black race (OR 0.72 vs 0.89; P for interactionâ =â .002). Conclusion: At the country level, sustained achievement of ABC goals and most especially non-HDLc were associated with substantial reductions in iCKD.

Background: Obtaining high quality RNA from skin biopsies is complex due the physical composition and high content of nucleases of this tissue. This becomes particularly challenging when using compromised skin samples with necrotic, inflammed or damaged areas, such as those from patients suffering skin conditions, which affect more than 900 million people annually. We evaluated the impact of the biopsy size and tissue preservation method on the quality and quantity of RNA extracts. Methods: Skin lesion biopsies were obtained from patients with cutaneous leishmaniasis (CL). Biopsy specimens of 2 mm (n = 10) and 3 mm (n = 59) were preserved in Allprotect® reagent, and 4 mm biopsies in OCT (n = 54). Quality parameters were evaluated using Nanodrop and Bioanalyzer. The informativeness of the extracted samples for downstream analyses was evaluated using RT-qPCR and RNA-Seq. Results: The success rate, based on quality parameters of RNA extraction from tissue biopsies stored in OCT and 2 mm biopsies stored in Allprotect®, was 56% (30/54) and 30% (3/10), respectively. For 3 mm skin biopsies stored in Allprotect® was 93% (55/59). RNA preparations from 3 mm-Allprotect® biopsies had an average RIN of 7.2 ± 0.7, and their integrity was not impacted by sample storage time (up to 200 days at -20°C). RNA products were appropriate for qRT-PCR and RNA-seq. Based on these results, we propose a standardized method for RNA extraction from disrupted skin samples. This protocol was validated with lesion biopsies from CL patients (n = 30), having a success rate of 100%. Conclusions: Our results indicate that a biopsy size of 3 mm in diameter and preservation in Allprotect® for up to 200 days at -20°C, are best to obtain high quality RNA preparations from ulcerated skin lesion biopsy samples.

Resumen Objetivo: Describir la supervivencia a siete años y los principales factores asociados a esta, en las personas con VIH que fueron atendidas en el sistema de salud colombiano entre 2011 a 2018. Métodos: Análisis de supervivencia de una cohorte de 64 039 personas diagnosticadas con VIH en Colombia. Se aplicó el método de Kaplan-Meier para estimar la probabilidad de supervivencia a partir de la fecha del diagnóstico. Se ajustó un modelo de supervivencia paramétrico flexible de Royston Parmar. Resultados: La estimación de la supervivencia global a 7 años fue de 94,8% (IC 95%: 94,5-95,2). El mayor riesgo de muerte se presentó en los hombres (HR: 1,2; IC 95%: 1,1-1,4; p: 0,010); en personas ≥50 años de edad (HR: 3,1; IC 95%: 1,6-6,3; p: 0,002); en el régimen subsidiado (HR: 2,2; IC 95%: 1,9-2,5; p: <0,001); en la etapa sida (HR: 2,8; IC 95%: 2,1-3,7; p: <0,001); en quienes presentaron la última carga viral detectable (HR: 7,1; IC 95%: 6,0-8,3; p: <0,001); y en quienes mostraron conteo de linfocitos T CD4+ <350 células/μL (HR: 1,9; IC 95%: 1,4-2,4; p: <0,001). Conclusión: La probabilidad de la supervivencia de las personas que viven con VIH aumenta al ser diagnosticados en edades jóvenes, en quienes presenten un recuento de linfocitos T CD4+ ≥350 células/μL, una carga viral indetectable (< 50 copias/mL) y no se encuentren en etapa sida.
Summary Objective: to describe the seven-year survival and predictors of mortality among people with HIV who were treated in the Colombian health system between 2011 and 2018. Methods: 64 039 people diagnosed with HIV in Colombia were included. Kaplan-Meier analysis estimated the probability of survival from the date of diagnosis. A Royston Parmar flexible parametric survival model was fitted. Results: The overall survival at 7 years was 94.8% (95% CI: 94.5-95.2). Survival was related to sex (men, HR: 1.2; 95% CI: 1.1-1.4; p: 0.010); people ≥50 years of age (HR: 3.1; 95% CI: 1.6-6.3; p: 0.002); subsidized regime (HR: 2.2; 95% CI: 1.9-2.5; p: <0.001); AIDS stage (HR: 2.8; 95% CI: 2.1-3.7; p: <0.001); a detectable viral load (HR: 7.1; 95% CI: 6.0-8.3; p: <0.001); and a CD4+ Lymphocyte count <350 cells/μL (HR: 1.9; 95% CI: 1.4-2.4; p: <0.001). Conclusion: The probability of survival of people living with HIV increases when they are diagnosed at a young age, in those with a CD4+ T Lymphocyte count ≥350 cells/μL, an undetectable viral load (<50 copies/mL) and are not in the AIDS stage.

BACKGROUND: Achieving an optimal glycemic control has been described to reduce the incidence of diabetes mellitus (DM) related complications. The association between comorbidities and glycemic control remains unclear. Our aim is to evaluate the effect of comorbidities on glycemic control in people living with DM. METHODS: A retrospective longitudinal study on data from the National Registry of Chronic Kidney Disease from 2014 to 2019 in Colombia. The outcome was poor glycemic control (PGC = HbA1c ≥7.0%). The association between each comorbidity (hypertension (HTN), chronic kidney disease (CKD) or obesity) and PGC was evaluated through multivariate mixed effects logistic regression models. The measures of effect were odds ratios (OR) and their 95% confidence intervals (CI). We also evaluated the main associations stratified by gender, insurance, and early onset diabetes as well as statistical interaction between each comorbidity and ethnicity. RESULTS: From 969,531 people at baseline, 85% had at least one comorbidity; they were older and mostly female. In people living with DM and CKD, the odds of having a PGC were 78% (OR: 1.78, CI 95%: 1.55-2.05) higher than those without CKD. Same pattern was observed in obese for whom the odds were 52% (OR: 1.52, CI 95%: 1.31-1.75) higher than in non-obese. Non-significant association was found between HTN and PGC. We found statistical interaction between comorbidities and ethnicity (afro descendant) as well as effect modification by health insurance and early onset DM. CONCLUSIONS: Prevalence of comorbidities was high in adults living with DM. Patients with concomitant CKD or obesity had significantly higher odds of having a PGC.

RESUMEN Objetivo Caracterizar, en lo que a ingeniería clínica se refiere, el estado actual de una IPS de nivel II de mediana complejidad del departamento de Norte de Santander (Colombia). Metodología Se recopiló información de referencia sobre la disponibilidad de servicios de salud y los equipos médicos con el fin de determinar necesidades en tecnologías sanitarias basados en el análisis de los datos demográficos y epidemiológico. Resultados En el estudio se encontró que el área de influencia es grande para la poca capacidad instalada con la que cuenta la IPS. Se debe priorizar la adquisición de equipos biomédicos para las enfermedades no transmisibles. Se determinó que existen necesidades en cuanto al equipamiento biomédico y recursos humanos para el oportuno desarrollo de la prestación de los servicios. Discusión Teniendo en cuenta la situación actual de la pandemia ocasionada por el COVID-19, se evidencia que las IPS requieren que estas necesidades sean cubiertas con el fin de evitar un aumento en los casos de infectados y dar una atención oportuna a quienes padezcan esta enfermedad. Por ello se requiere un aumento de la capacidad Instalada de equipos biomédicos y servicios asistenciales. Esta caracterización va a permitirles a las IPS determinar cuáles son las carencias en equipos biomédicos, lo cual se hace fundamental en este momento, cuando se requiere un fortalecimiento de los servicios de salud que se prestan en el país.
ABSTRACT Objective To characterize the current state of the clinical engineering in a medium complexity (level 2) health institution in Norte de Santander, a State of Colombia, South America. Methodology Reference information was collected on the availability of health services and medical equipment to determine needs in health technologies based on the analysis of demographic and epidemiological data. Results The study resulted in that the area of influence is big y this have a little installed capacity, the acquisition of biomedical equipment for non-communicable diseases should be prioritized. It was determined that there are needs in terms of biomedical equipments and human resources for the timely development of the provision of services. Discussion Due to the current situation of the pandemic caused by COVID-19, it is evident that the IPS require that the needs be covered to avoid an increase in the cases of ¡nfected and assist the sick people, for that reason, an increase in the installed capacity of biomedical equipment and healthcare services is required. Finally, according to the economic aspect of the IPS, there are possible limitations for the acquisition of necessary biomedical equipment. This characterization will allow the IPS to determine what are the shortcomings in biomedical equipment, which is essential at this time when a strengthening of the health services provided in the country is required.
RESUMO
Background: A high-throughput method using inductively coupled plasma mass spectrometry (ICP-MS) was developed and validated for the quantitative analysis of antimony in human plasma and peripheral blood mononuclear cells from patients with cutaneous leishmaniasis undergoing treatment with meglumine antimoniate. Materials & methods: Antimony was digested in clinical samples with 1% tetramethylammonium hydroxide/1% EDTA and indium was used as internal standard. Accuracy, precision and stability were evaluated. Conclusion: Taking the lower limit of quantitation to be the lowest validation concentration with precision and accuracy within 20%, the current assay was successfully validated from 25 to 10000 ng/ml for antimony in human plasma and peripheral blood mononuclear cells. This protocol will serve as a baseline for future analytical designs, aiming to provide a reference method to allow inter-study comparisons.
Lay abstract Cutaneous leishmaniasis is a disease caused by single-cell parasites in the genus Leishmania which results in painful skin ulcers and is spread by insect bites. Drugs containing antimony are the mainstay therapy for cutaneous leishmaniasis, but if and how the amount of these compounds in the cells can affect the success of the treatment, remains unknown. Validated methods to reliably measure these amounts in human cells are limited. Here we have developed a validated method that allows quantifying antimony in human plasma and peripheral blood cells from patients undergoing antileishmanial treatment. This protocol will serve as a baseline for future studies aiming to understand how antimonials work to treat leishmaniasis infections and how this therapy can be improved.

Resumen Del 20% al 30% de los pacientes con colitis ulcerativa (CU) son sometidos a cirugía, ya sea por intratabilidad, curso fulminante, aparición de displasia o cáncer de colon. La cirugía de elección es la proctocolectomía con reservorio ileoanal. Sin embargo, el 20%-50% de los pacientes presentan reservoritis a 10 años. El diagnóstico se realiza con base en las manifestaciones clínicas, las alteraciones endoscópicas y la histología. Los medicamentos utilizados en el tratamiento de la CU no son tan eficaces en la reservoritis y el tratamiento de primera línea es los antibióticos. Dependiendo de la respuesta inicial y el curso clínico de la entidad, se elegirá el tratamiento posterior. En esta revisión se discuten los aspectos más importantes con respecto a la epidemiología, diagnóstico, patogénesis y tratamiento de la reservoritis.
Abstract Between 20% and 30% of patients with ulcerative colitis (UC) undergo surgery because it is not treatable or because it is associated with a fulminant course, dysplasia, or colon cancer. The surgery of choice is proctocolectomy with ileal-anal pouch. However, 20%-50% of patients present with pouchitis 10 years after surgery. The diagnosis is made based on clinical manifestations, endoscopic alterations, and histology. The drugs used in the treatment of UC are not as effective in pouchitis and the first-line treatment is antibiotics administration. Depending on the initial response and clinical course of the condition, subsequent treatment will be chosen. This review discusses the most important aspects of the epidemiology, diagnosis, pathogenesis, and treatment of pouchitis.

BACKGROUND: Control of cutaneous leishmaniasis (CL) relies on chemotherapy, yet gaps in our understanding of the determinants of therapeutic outcome impede optimization of antileishmanial drug regimens. Pharmacodynamic (PD) parameters of antimicrobials are based on the relationship between drug concentrations/exposure and microbial kill. However, viable Leishmania persist in a high proportion of individuals despite clinical resolution, indicating that determinants other than parasite clearance are involved in drug efficacy. METHODS: In this study, the profiles of expression of neutrophils, monocytes, Th1 and Th17 gene signatures were characterized in peripheral blood mononuclear cells (PBMCs) during treatment with meglumine antimoniate (MA) and clinical cure of human CL caused by Leishmania (Viannia). We explored relationships of immune gene expression with plasma and intracellular antimony (Sb) concentrations. RESULTS: Our findings show a rapid and orchestrated modulation of gene expression networks upon exposure to MA. We report nonlinear pharmacokinetic/pharmacodynamic (PK/PD) relationships of Sb and gene expression dynamics in PBMCs , concurring with a time lag in the detection of intracellular drug concentrations and with PK evidence of intracellular Sb accumulation. CONCLUSIONS: Our results quantitatively portray the immune dynamics of therapeutic healing, and provide the knowledge base for optimization of antimonial drug treatments, guiding the selection and/or design of targeted drug delivery systems and strategies for targeted immunomodulation.

Resumen Las enfermedades de transmisión vectorial (ETV), como dengue, zika y chikungunya, representan un problema de salud pública en Colombia. Autoridades e instituciones de salud municipales promovieron campañas de prevención y manejo de los factores asociados a estas enfermedades. No obstante, el municipio de Ocaña registró una alta prevalencia. Se realizó un análisis de contenido a 14 mensajes comunicativos impresos orientados a la prevención de enfermedades de transmisión vectorial durante el período de 2014 a junio de 2016. Las unidades de análisis comprendieron términos referidos a la enfermedad, términos generales, partes del texto (frases y oraciones) y función y objetivo de la imagen, bajo los constructos control y prevención de ETV con los códigos de vector, enfermedad y público. Se emplearon como instrumentos de recolección y análisis de datos los siguientes: instrumento de evaluación de material educativo de la OPS, instrumento específico ad-hoc para evaluación de contenido y la prueba objetiva INFLESZ. Si bien, el grado de legibilidad de las unidades comunicativas fue de 'normal' hasta 'muy fácil', se identificaron oportunidades de mejora para la comprensión e identificación del público meta, necesarios para la educación en salud, que no genere interpretaciones contrapuestas desde los aspectos semióticos y semánticos sobre conductas y comportamientos, y sobre todo, que se perciba como un mensaje que va dirigido a un público específico, con la exigencia de contextualización frente a los lineamientos generales y la participación de la comunidad.
Abstract Vector-borne diseases (VTD), such as dengue, zika and chikungunya, represent a public health problem in Colombia. Municipal authorities and health institutions promoted campaigns to prevent and manage the factors associated with these diseases. However, the municipality of Ocaña registered a high prevalence. A content analysis was carried out on 14 printed communicative messages aimed at preventing vector-borne diseases during the period from 2014 to June 2016. The analysis units included terms referring to the disease, general terms, parts of the text (phrases and sentences) and function and objective of the image, under the control and prevention constructs of VTD with the vector, disease and public codes. The following instruments were used as data collection and analysis instruments: PAHO educational material evaluation instrument, ad-hoc specific instrument for content evaluation and the INFLESZ objective test. Although the legibility of the communicative units was from 'normal' to 'very easy', opportunities for improvement were identified for the understanding and identification of the target audience, necessary for health education, which does not generate conflicting interpretations from the semiotic and semantic aspects about behaviors and behaviors, and above all, that it is perceived as a message that is addressed to a specific audience, with the requirement of contextualization in front of the general guidelines and community participation.
