Ecoepidemiology of Ancylostoma spp. in Urban-Marginal and Rural Sectors of the Ecuadorian Coast and Prevalence of Cutaneous Larvae Migrans.

BACKGROUND Ancylostoma spp., including A. duodenale, A. braziliense, A. caninum, and A. ceylanicum, are hookworms that are transmitted from infected soil and by contact with domestic animals and rodent hosts, and can cause systemic disease and cutaneous larva migrans. The objective of this study was to describe the ecoepidemiology of Ancylostoma caninum and Ancylostoma spp. in urban-marginal sectors and in rural sectors located in Ecuador. MATERIAL AND METHODS Through addressed sampling, a total of 498 domestic dogs and 40 synanthropic rodents were analyzed via the following coproparasitic methods: direct, flotation, sedimentation with centrifugation using saline (egg identification), modified Baermann (larval identification), and morphometric methods (confirmation). A total of 236 people were surveyed, and a clinical analysis was performed via physical examination. The environmental variables were obtained through reports from the INAMHI of Ecuador and the use of online environmental programs. Through surveys, data related to social determinants were obtained. Epidemiological indicators (prevalence, morbidity, and mortality) were obtained through microbial analysis and surveys. RESULTS A total of 250 domestic dogs were diagnosed with Ancylostoma caninum (50, 20%), and 41 were diagnosed with Ancylostoma spp. (8.23%). One synanthropic rodent (2.5%) was positive for A. caninum. In the clinical analysis, 3 patients were identified as positive (1.27%) for cutaneous larva migrans (CLM). Likewise, environmental variables and social determinants influence the transmission, prevalence, and nature of parasitism by hookworm. CONCLUSIONS People, domestic dogs, and rodents were infected with these parasites. Consequently, there is a risk of ancylostomiasis and cutaneous larvae migrans spreading.

A Case of Urbanorum spp. in a Woman from an Urban-Marginal Sector of Ecuador.

BACKGROUND Worldwide, there are few cases of Urbanorum spp. in humans; however, it is associated with gastrointestinal pathologies, where humans probably acquire the disease by fecal-oral transmission, by ingesting food or water with infective cysts. The main symptoms of the patients who have this presumed parasite are fever, vomiting, colic, dyspepsia, and watery diarrhea. Since the first case of Urbanorum spp. was reported in 1994 in Colombia, cases have subsequently been reported in Peru, Ecuador, Colombia, Brazil, and Mexico. In Ecuador, a prevalence of 1.16% has been reported, and the objective of this study was to record another case of Urbanorum spp. infection in Ecuador. CASE REPORT A female patient (mixed race; 40 years old; and thin, weighing 57 to 62 kg) requested help from the FCI Project approved and financed by the University of Guayaquil (Ecuador). She underwent routine tests, such as direct parasitology and sedimentation with centrifugation using saline solution. Samples were observed under an optical microscope with 10x and 40x objectives and stained with and without Lugol's solution. We detected a rounded structure with several filaments similar to light yellow pseudopods. CONCLUSIONS Herein, a case of Urbanorum spp. infection in Ecuador, where current environmental and sanitary conditions have contributed to new cases, is reported, indicating that the community was exposed to this probable parasite with importance in public health. Further studies are recommended to confirm its etiology, life cycle, and epidemiology, in order to create a national registry, in case it is defined as a protozoan.

Zoonotic Transmission of Hepatic Hydatid Cyst from Domestic Dogs: A Case Report from an Urban-Marginal Area in Ecuador.

BACKGROUND Hepatic hydatidosis, or echinococcosis, is a zoonosis with worldwide prevalence and is potentially lethal in humans. This report presents a case of hydatidosis in a 40-year-old woman that was associated with a zoonotic transmission of Echinococcus granulosus from domestic dogs in an urban-marginal area of the city of Guayaquil, Ecuador. This report shows how early diagnosis and awareness favored the correct treatment of the disease. CASE REPORT A 40-year-old woman from the aforementioned sector presented the following symptoms: malaise, pain in the upper right hypochondrium, palpable mass, jaundice, and fever. Next, the patient's fecal samples were analyzed by direct coproparasitic methods, flotation, and sedimentation with centrifugation using saline solution, whereby the presence of Entamoeba histolytica eggs was determined. Likewise, she underwent an ultrasound, in which hepatic hydatid cysts were observed. Subsequently, the cysts were treated and surgically removed, and parasitic forms of E. granulosus were identified. Later, coproparasitic analysis of her 2 domestic dogs for coproantigen ELISA were performed, by which the presence of this cestode was also identified and confirmed. CONCLUSIONS Hydatidosis is a zoonosis that can affect the population, especially in endemic areas of developed and underdeveloped countries. In this case, hepatic hydatidosis was identified in a 40-year-old woman. Additionally, the presence of E. granulosus eggs was determined in the fecal matter of her dogs, which indicated that the patient's relatives and other people around them were exposed to this zoonosis.

Hymenolepiasis Caused by Hymenolepis nana in Humans and Natural Infection in Rodents in a Marginal Urban Sector of Guayaquil, Ecuador.

BACKGROUND Hymenolepiasis is a globally prevalent zoonosis of the monoxenic cycle. Humans acquire the disease through fecal-oral transmission by ingesting food or water with infective eggs from infected rodents. This report presents 3 cases of hymenolepiasis in children, due to zoonotic transmission from rodents and presumably associated with the consumption of powdered milk contaminated with infective eggs of Hymenolepis nana, and shows that awareness and early diagnosis contributed to timely treatment of the disease. CASE REPORT Three children, aged 9, 12, and 13 years, living in a marginal urban area of Guayaquil, Guayas province, Ecuador, presented symptoms of diarrhea, low body weight, abdominal discomfort, anorexia, paleness, and anal itching. Subsequently, their fecal samples were analyzed by direct coproparasitic methods, flotation and sedimentation with centrifugation using saline solution; the presence of H. nana eggs was determined. Blood biometry was performed. Further, 10 rodents were captured and necropsied to obtain intestinal contents. The powdered milk consumed by the children was analyzed, the same powder that contained rodent feces. Subsequently, these were studied with the above-mentioned coproparasitic methods. H. nana eggs were identified in the 6 trapped rodents, the powdered milk, and the feces of rodents found in the milk powder. CONCLUSIONS Hymenolepiasis can affect populations of endemic areas. In this case, the disease was identified in 3 children, who were diagnosed with eosinophilia and anemia. Additionally, the presence of H. nana eggs in captured rodents and in powdered milk was determined, indicating that the community was exposed to this zoonotic disease.

Multidrug-Resistant Klebsiella pneumoniae in a Patient with SARS-Cov-2 Pneumonia in an Intensive Care Unit in Guayaquil, Ecuador: A Case Report.

BACKGROUND Multi-resistant microorganisms are a public health problem. Their incidence has risen due to COVID-19, indiscriminate antibiotics use, corticosteroid treatments, and higher admissions to intensive care units (ICUs) of patients requiring invasive mechanical ventilation. These are risk factors for bacterial over-infection. The present case study that is relevant because of the multiple isolated strains with a resistance pattern: Klebsiella pneumoniae carbapenemases (KPC), extended-spectrum beta lactamases (ESBL) and New Delhi metallo-ß-lactamase (NDM) in a patient without comorbidities. CASE REPORT A 53-year-old Ecuadorian man with no past medical history arrived at the Emergency Department (ED) with dyspnea, nasopharyngeal swab with a positive reverse transcription polymerase chain reaction (RT-PCR) test for SARS-CoV2, and a chest computed tomography (CT) scan showing bilateral ground-glass pulmonary infiltrates with 40% involvement. On day 10 in the ICU, the presence of Klebsiella pneumoniae KPC strain was reported in an axillary swab culture. Consequently, the antibiotic was rotated to vancomycin 1 g intravenously (i.v.) every 12 h and meropenem 1 g i.v. every 8 h. On day 15 in the ICU, a tracheal secretion culture was reported with the presence of Klebsiella pneumoniae ESBL and a blood culture with Klebsiella pneumoniae NDM. CONCLUSIONS The COVID-19 pandemic is a perfect scenario for superinfection with multi-resistant pathogens such as carbapenem-resistant Klebsiella pneumoniae (CRKP), due to the increase in patients admitted to ICUs requiring invasive mechanical ventilation, the use of corticosteroids, and empirical broad-spectrum antibiotic management based on guidelines. The emergence of combined multidrug-resistant strains is a challenge for laboratory detection and the selection of antimicrobial treatment.

Natural infection of Trypanosoma sp. in domestic sheep from Ecuador / Infecção natural do Trypanosoma sp. em ovelhas domésticas do Equador

Trypanosomosis in sheep is a hemoparasitic disease of worldwide interest due to its effects on the health of animals and the economic impact on producers, is caused by the protozoan Trypanosoma sp. In the present study, the occurrence of Trypanosoma sp. in sheep from the urban-rural area of the canton Salitre was determined, through an applied study with a qualitative descriptive prospective cross-sectional approach, carried out between October 1, 2019, and February 19, 2020. Blood samples were extracted from the jugular vein and analyzed by the blood smear method using the Giemsa and Diff-Quick staining techniques. Previously, in a first study realized between 2018 and 2019, 2 cases (2%) of Trypanosoma sp., 1 case of Babesia sp. (1%), and 4 cases of Anaplasma marginale (4%) were identified, but without the presence of symptoms of the disease. However, in this new research study, of 170 animals sampled from 5 herds and aged between 3 and 8 years, 34 (20%) were positive for Trypanosoma sp., 6 for Babesia sp. (3.52%) and 6 for A. marginale (3.52%) with coinfection between them. In this research, deteriorated clinical aspects and low hematological values were also determined in positive animals; besides of the total of positive cases, 25 presented symptoms of hemoparasitic disease, 3 sheep had abortions and 8 died. The results of this study showed that Trypanosoma sp. could already become an endemic parasitosis in sheep in the country, representing a serious problem of animal health.

A tripanossomose em ovinos é uma doença hemoparasitária de interesse mundial devido a seus efeitos sobre a saúde dos animais e o impacto econômico sobre os produtores, Esta doença é causada pelo protozoário Trypanosoma sp. No presente estudo, foi determinada a ocorrência de Trypanosoma sp. em ovelhas da área urbano-rural do Cantão Salitre, através de um estudo aplicado com uma abordagem transversal descritiva qualitativa prospectiva, realizado entre dia primeiro de outubro de 2019, à 19 de fevereiro de 2020. Amostras de sangue foram extraídas da veia jugular e analisadas pelo método de esfregaço de sangue usando as técnicas de coloração Giemsa e Diff-Quick. Anteriormente, em um primeiro estudo realizado entre 2018 e 2019, dois casos (2%) de Trypanosoma sp., foram identificados um caso de Babesia sp. (1%), e quatro casos de Anaplasma marginale (4%), mas sem a presença de sintomas da doença. Entretanto, neste novo estudo de pesquisa, de 170 animais amostrados de cinco rebanhos e com idades entre três e oito anos, 34 (20%) foram positivos para Trypanosoma sp., seis para Babesia sp. (3,52%) e seis para A. marginale (3,52%) com coinfecção entre eles. Nesta pesquisa, aspectos clínicos deteriorados e baixos valores hematológicos também foram determinados em animais positivos; além do total de casos positivos, 25 apresentaram sintomas de doença hemoparasítica, três ovelhas tiveram abortos e oito morreram. Os resultados deste estudo mostram que o Trypanosoma sp. já poderia se tornar uma parasitose endêmica em ovinos no país, representando um grave problema de saúde animal.

Hemoglobina A1c, diabetes mellitus, nefropatía diabética y enfermedad renal crónica / Hemoglobin A1c, Diabetes Mellitus, Diabetic Nephropathy and Chronic Kidney Disease

La diabetes mellitus (DBT), la nefropatía diabética (ND) y la enfermedad renal crónica (ERC) son enfermedades prevalentes en nuestra región, Sudamérica. Los niveles de hemoglobina A1c (HbA1c) han sido relacionados al desarrollo y a la evolución de la ND. Hace dos décadas había gran variabilidad en los resultados, los países líderes en investigación científica organizaron programas de estandarización de la HbA1c, logrando mejorar la calidad y la confiabilidad de los resultados. Los objetivos de este trabajo fueron describir el problema DBT, ND y ERC en Sudamérica y en su contexto analizar metodológicamente la HbA1c. Para esto, revisamos el impacto de estas enfermedades en nuestra región, contemplando aspectos básicos de la HbA1c y algunas situaciones que producen interferencias como la carbamilación de la hemoglobina, modificación post-traduccional asociada a la uremia. También nos enfocamos en técnicas estadísticas universalmente utilizadas para la evaluación de ensayos como: linealidad, concordancia y precisión. Adicionalmente, incluimos un análisis de los métodos disponibles y de los precios de cada determinación de HbA1c en diez países de Sudamérica. Para prevenir, diagnosticar y tratar la DBT, la ND y la ERC es indispensable contar con herramientas de última generación, disponibles para todas las personas. En nuestra región el acceso a ensayos, equipos y laboratorios enmarcados en programas de estandarización de la HbA1c, internacionalmente aceptados, es una tarea pendiente. Millones de individuos de las generaciones presentes y futuras de Sudamérica padecerán DBT, ND y ERC, necesitamos llevar la voz de la ciencia a esas personas con el "hacer" cotidiano

Diabetes mellitus (DM), diabetic nephropathy (DN) and chronic kidney disease (CKD) are prevalent diseases in our region, South America. The levels of hemoglobin A1c (HbA1c) have been related to the development and progression of the DN. Two decades ago there was great variability in the results; the leading countries in scientific research then organized programs of HbA1c standardization, which improved the quality and reliability of the findings. The objectives of this study were to describe the problem of DM, DN and CKD in South America and to analyze HbA1c methodologically in this context. Thus, the impact of these diseases in our region was reviewed, contemplating basic aspects of HbA1c and some situations that produce interferences such as carbamylation of hemoglobin, the post-translational modification associated with uremia. We also focused on statistical techniques universally used for the evaluation of assays such as linearity, concordance and precision. Additionally, we included an analysis of the existing methods and the prices of each HbA1c determination in ten countries in South America. To prevent, diagnose and treat DM, DN and CKD, it is essential to have state-of-the-art tools available to all people. In our region, access to trials, equipment and laboratories within HbA1c standardization programs, internationally accepted, is a pending task. Millions of individuals from the present and future generations of South America will suffer from DM, DN and CKD, so we need to take the voice of science to these people through the daily "doing"

Atención psicosocial integral en enfermedad catastrófica (Atinar) / Integrative Psychosocial Care in Catastrophic Illness

La enfermedad médico-quirúrgica catastrófica (EMQ-C) se define como una enfermedad aguda o prolongada, usualmente considerada como amenazante para la vida o con el riesgo de dejar discapacidad residual importante. La EMQ-C , a menudo, conlleva trastornos psicosociales que afectan de manera importante su evolución, porque alteran el proceso de rehabilitación, los hábitos saludables y la calidad de vida y, además, limitan la adherencia al tratamiento. Por lo tanto, para ofrecer un tratamiento a la persona quien la padece, es necesario desarrollar modelos que permitan identificar y tratar integralmente todos los aspectos médicos, psicológicos y sociales. La legislación colombiana, desde la aprobación de la Ley 100 de 1993, reglamentó la atención integral de la EMQ-C. No obstante, el desarrollo de programas de atención integral que incluyan lo psicosocial ha sido lento. Se presenta un modelo teórico de atención psicosocial integral en EMQ-C, que sigue los lineamientos de la medicina biopsicosocial de Ángel, junto a un modelo denominado medicina cognitiva , desarrollado previamente por uno de los autores (HR). El modelo incluye aspectos y procedimientos necesarios para su funcionamiento ajustado a la ley colombiana.

Medical Surgical Catastrophic Illness (MSIC) is defined as an acute or chronic lifethreatening disease or with risk of important disability. MSI-C is frequently associated with Psychosocial Disorders influencing the outcome due to effects on the rehabilitation process, quality of life and compliance. The development of integrative models of care that cover medical, psychological and social aspects is necessary in order to offer treatment to the person with MSI-C. Since Law 100 of 1993 was passed, Colombia ruled an integrative model of care for catastrophic illness. Noteworthy, implementation of these programs has been slow. In this article a theoretical model of integrative psychosocial care that follows recommendations of Engel's Biopsychosocial Model and the Cognitive Medicine model developed by one of the authors (HR). The model includes necessary aspects and procedures for its implementation according to Colombian Law.

Evaluación: programa de prevención secundaria y terciaria del alcoholismo en el nivel primario de atención de salud 1983-1985 / Evaluation: program of secondary and terciary prevention of alcoholism in primary health care level 1983-1985

El Programa de Prevención Secundaria y Terciaria del alcoholismo en el nivel Primario de atención de salud del SSMS se efectúa en los 19 Consultorios Periféricos a cargo del equipo de salud general, conformado por médico, asistente social y enfermera. La coordinación la efectúa el Programa de las Personas y el DAP del SSMS en conjunto con la Comisión Asesora de Salud Mental, compuesta por los autores de este trabajo. Que, además, asesora, supervisa y capacita al equipo de salud de los Consultorios Periféricos y coordina al nivel primario con los niveles secundarios (Servicios de Psiquiatría del Hospital Barros Luco-Trudeau) y terciarios (Hospital Sanatorio El Peral). Se presenta la evaluación del Programa de Alcoholismo de los 470 pacientes ingresados a él en el Primer Semestre de 1983 que han sido seguidos hasta el 30.06.85. Se efectuá cinco cortes evaluativos al 30.06.83; 31.12.83; 30.06.84; 31.12.84 y 30.06.85. Se compara la evolución de los 8 indicadores utilizados en los cortes: abstinencia, recaída, inasistencia, abandono, referencia, traslado, muerte y alta. Al 30.06.85 en el 42.96% de los 470 pacientes ha fracasado el tratamiento. Tienen recaída (1.91%), inasistencia (9.14%) o han abandonado (31.91%). El 21.27% han sido referidos a atención secundaria (4.46%) o han sido trasladados 16.81%) a otras áreas del país. Han muerto el 5.53%. El 30.85% restantes están abstinentes (14.04% o han sido dados de alta 16.17%). Al excluir el rubro otros egresos (referencia, traslado y muerte), y corregir sobre el nuevo total, los tramientos exitosos (abstinencia y alta) significan el 41.27%
