RESUMO
OBJECTIVE: To examine the associations of sociodemographic, socioeconomic, and behavioral factors with depression, anxiety, and self-reported health status during the COVID-19 lockdown in Ecuador. We also assessed the differences in these associations between women and men. DESIGN, SETTING, AND PARTICIPANTS: We conducted a cross-sectional survey between July to October 2020 to adults who were living in Ecuador between March to October 2020. All data were collected through an online survey. We ran descriptive and bivariate analyses and fitted sex-stratified multivariate logistic regression models to assess the association between explanatory variables and self-reported health status. RESULTS: 1801 women and 1123 men completed the survey. Their median (IQR) age was 34 (27-44) years, most participants had a university education (84%) and a full-time public or private job (63%); 16% of participants had poor health self-perception. Poor self-perceived health was associated with being female, having solely public healthcare system access, perceiving housing conditions as inadequate, living with cohabitants requiring care, perceiving difficulties in coping with work or managing household chores, COVID-19 infection, chronic disease, and depression symptoms were significantly and independently associated with poor self-reported health status. For women, self-employment, having solely public healthcare system access, perceiving housing conditions as inadequate, having cohabitants requiring care, having very high difficulties to cope with household chores, having COVID-19, and having a chronic disease increased the likelihood of having poor self-reported health status. For men, poor or inadequate housing, presence of any chronic disease, and depression increased the likelihood of having poor self-reported health status. CONCLUSION: Being female, having solely public healthcare system access, perceiving housing conditions as inadequate, living with cohabitants requiring care, perceiving difficulties in coping with work or managing household chores, COVID-19 infection, chronic disease, and depression symptoms were significantly and independently associated with poor self-reported health status in Ecuadorian population.

RESUMO
RESUMEN Introducción: La hipertensión arterial (HTA) es la primera causa de morbimortalidad cardiovascular. A menudo es una enfermedad mal controlada porque los sistemas de salud están más orientados a atender enfermedades agudas. El Ministerio de Salud de Argentina propuso un nuevo modelo de atención para pacientes hipertensos conocido como MAPEC, basado en el Modelo de cuidados crónicos. Objetivo: Evaluar el impacto de la implementación del MAPEC en el control de la presión arterial (PA), el cuidado de las medidas higiénico-dietéticas, el conocimiento de la enfermedad y la adherencia al tratamiento en pacientes hipertensos asistidos en tres centros de atención primaria de la ciudad de Salta, Argentina. Material y Métodos: Se midió la PA con tensiómetro digital automático; se evaluó el conocimiento de la HTA y la adherencia al tratamiento con los test de Batalla y Morisky-Green-Levine, respectivamente. Resultados: Se estudiaron 232 pacientes. Hubo diferencias significativas (p <0,0001) luego de la intervención en el control de la PA, el conocimiento de la enfermedad, la adherencia al tratamiento y las medidas higiénico-dietéticas. También en los promedios de PA, con una disminución de 12,97 (IC95: 9,52-16,42) mmHg en la presión sistólica y de 6,93 (IC95: 4,70-9,16) mmHg en la presión diastólica. Conclusiones: Fue evidente la mejoría en los parámetros de salud analizados en los pacientes con la implementación del MAPEC. Este modelo es de fácil aplicación y bajo costo. Además, está en consonancia con los objetivos 25×25 de la OMS, mediante los que se busca una reducción del 25% de las muertes prematuras por enfermedades cardiovasculares hacia el año 2025.
ABSTRACT Background: blood hypertension is the first cause of worldwide cardiovascular morbidity and mortality. Nevertheless, it is a poorly controlled disease, largely because health care systems are oriented to the attention of acute diseases. The Argentine Ministry of Health proposed a new care model for hypertensive patients called MAPEC, based on the Chronic Care Model. Objective: to evaluate the impact made by the implementation of MAPEC to improve the blood pressure control, the treatment adherence and changes in life style, and disease awareness, in three primary health centers of Salta city Argentine. Methods: the blood pressure was measured with automated device, Batalla and Morisky-Green-Levine were used to evaluate the disease awareness and treatment adherence, respectively. Results: 232 patients were included. After model implementation, significant difference (p<0,0001) were found in blood pressure control, disease awareness, treatment adherence and changes in life style. There was a decrease in blood pressure average with reduction of 12,97 (IC 95: 9,52-16,42) mm Hg and 6,93 (IC 95: 4,70-9,16) mm Hg in sistolic and diastolic pressure, respectively. Conclusions: there was evident improvement in the analyzed health parameters after MAPEC implementation. This can be easily adapted for primary health centers and with low cost. This is in order with WHO 25×25 target to reduce 25% cardiovascular premature deaths in 2025.
RESUMO
Background: Pneumonia caused 704,000 deaths in children younger than 5 years in 2015. Zinc is an important micronutrient due to its role in immune function. Since 2004, WHO recommends zinc supplementation for children with diarrhea to shorten the duration and decrease severity. Zinc supplementation for children with pneumonia is controversial. Methods: A randomized controlled clinical trial was conducted, and 103 children 1 month to 5 years old with pneumonia were included. Zinc or placebo was given during hospitalization. Clinical symptoms were recorded, and a blood draw was obtained to determine serum zinc levels, lymphoproliferation, and cytokines at hospitalization and at discharge of the patient; a nasal wash was obtained to detect viral or bacterial pathogens by multiplex RT-PCR. Results: Zinc supplementation improved in fewer hours the clinical status (76 ± 7 vs. 105 ± 8, p = 0.01), the respiratory rate (37 ± 6 vs. 57 ± 7, p = 0.04), and the oxygen saturation (53 ± 7 vs. 87 ± 9, p = 0.007) compared to the placebo group. An increase in IFNγ and IL-2 after treatment in the zinc group was observed. Conclusions: Zinc supplementation improved some clinical symptoms in children with pneumonia in fewer hours and induced a cellular immune response. Clinical Trial Registration: The trial was retrospectively registered in ClinicalTrials.gov, identifier NCT03690583, URL https://clinicaltrials.gov/ct2/show/NCT03690583?term=zinc+children&cond=Pneumonia&draw=2&rank=1.
RESUMO
OBJECTIVE: To determine the cost of medical care in patients with gonarthrosis. MATERIAL AND METHODS: Cost study in patients over 40 years of age with gonarthrosis, diagnosed according to the radiological classification of Kellgren and Lawrence. The average annual cost (euros) was estimated taking the unit cost plus average use of services such as family medicine, imaging, laboratory, electrodiagnosis, orthopedics, hospitalization, physical therapy, surgery, nutrition, preoperative assessment and medication. Projections based on assumptions were made for three scenarios. RESULTS: Grade 2 gonarthrosis predominated at 39.7% (95% confidence interval, 33.8 - 45.6). The annual cost of care for a patient with gonarthrosis was 108.87 in the intermediate scenario, 86.73 in the lower cost scenario and 132.60 in the higher cost scenario. For a population of 119,530,753 inhabitants, with 10,937,064 gonarthrosis patients, the annual cost in the intermediate scenario was 1,190,685,273 and represented 4.48% of the health expenditure. CONCLUSION: The average annual cost of gonarthrosis is relatively low, but when related to prevalence and prevalence trends, it can become a serious problem for health services.

INTRODUCTION: obesity is a global health epidemic and understanding its causes is essential for successful treatment and prevention. Cravings have been associated with the excessive consumption of sugars and fats, and addictive eating behavior. OBJECTIVE: to determine the strength of the relationship between cravings, the consumption of sugar and fat, and its impact on body composition as determined via body mass index (BMI), body fat percentage (BFP) and waist circumference (WC) in a sample of Mexicans who reside close to the México-U.S. border. METHODS: the sample was comprised of 159 young adults with a mean age of 27.96 ± 6.19, 45.9% of which were male, and all residents of Ciudad Juarez, Mexico. Cravings were measured using Trait and State Food Cravings Questionnaires. The consumption of sugars and fats was determined via a 24-hour recall of foods consumed and a food consumption frequency questionnaire. RESULTS: it was demonstrated that BMI and BFP were positively associated with responses to the craving questionnaires and WC with fat consumption. Additionally, higher fat consumption was positively associated with higher rates of obesity. CONCLUSIONS: the results demonstrate the need to identify the presence of cravings and integrate such measures for effective prevention and treatment of obesity.

La menopausia ha sido definida por la Sociedad Internacional de Menopausia como el cese permanente de la menstruación en la mujer, suceso determinado por la disminución de la producción hormonal. Trae consigo, por una parte, una sintomatología que interfiere en la calidad de vida de la mujer, la cual incluye síntomas vasomotores, psíquicos, atrofia urogenital; y, por otra, cambios metabólicos que implican aumento del riesgo de enfermedades crónicas como las enfermedades cardiovasculares y la osteoporosis. Con el progresivo aumento de la esperanza de vida, los grupos de mayor edad comienzan a ser parte importante de la población mundial. Por lo tanto, el manejo clínico de la posmenopausia pasa a ser un problema relevante de salud pública. Tiene como objetivo mejorar la calidad de vida y disminuir el riesgo de enfermedades crónicas. Para medir la existencia de síntomas y signos asociados a la menopausia se puede utilizar la Menopause Rating Scale (MRS), escala que permite evaluar la intensidad de la sintomatología. Se debe valorar además el riesgo cardiovascular y de osteoporosis. El tratamiento incluye mejorar los estilos de vida, el uso de terapia hormonal y de terapias para las comorbilidades. Estas orientaciones tienen como objetivo ser una ayuda para el médico al momento de evaluar a una mujer en este periodo de la vida. Se han basado principalmente en las 'Orientaciones Técnicas para la atención integral de la mujer en edad de climaterio en el nivel primario de red de salud' del Programa de Salud de la Mujer, Ministerio de Salud, Chile. Sin embargo, son solo orientaciones; cada decisión terapéutica debe ser siempre individualizada acorde a las características particulares de cada paciente.
Menopause has been defined by the International Menopause Society as the permanent cessation of menstruation in women, an event determined by the decrease in hormonal production. On one hand, the associated symptomatology interferes with the quality of life of the woman, and includes vasomotor and psychic symptoms and urogenital atrophy; on the other hand, metabolic changes that imply an increase in the risk of chronic diseases such as cardiovascular disease and osteoporosis. With the progressive increase in life expectancy, the older groups begin to be an important part of the world population. Therefore, the clinical management of the postmenopause becomes a relevant public health problem. Its objective is to improve the quality of life and reduce the risk of chronic diseases. The Menopause Rating Scale (MRS) is a scale to assess the existence and intensity of symptoms. Cardiovascular risk and osteoporosis should also be assessed. Treatment includes improving lifestyle, the use of hormonal therapy and therapies for comorbidities. These guidelines are intended to be an aid to the physician when evaluating a woman in this period of life. They have been based mainly on the "Technical Guidelines for the comprehensive care of women of climacteric age at the primary level of the health network" of the Women's Health Program, Ministry of Health, Chile. However, they are only orientations. Every therapeutic decision should be individualized according to the particular characteristics of each patient.
RESUMO
INTRODUCCIÓN La HTA crónica no está bien atendida por el sistema de salud. El Ministerio de Salud de la Nación propuso un nuevo modelo para la atención de las personas con enfermedades crónicas (MAPEC). OBJETIVOS Evaluar el impacto de la implementación del MAPEC en pacientes hipertensos de 3 Centros de Atención Primaria de la Salud (CAPS) de Salta, de junio-2018 a enero-2019. METODOS Estudio cuasi experimental de serie de medidas repetidas, con un control externo no equivalente (3 CAPS No MAPEC). Los pacientes fueron hipertensos medicados (≥18 años), excluyendo embarazadas e HTA secundaria. Se implementaron los 6 componentes del MAPEC (CAPS MAPEC). La PA se midió con tensiómetros digitales validados según las guías de práctica clínica. RESULTADOS Grupo MAPEC; 232 pacientes (Edad media 58,01 ± 10,7 años; 35,34% masculinos); grupo No MAPEC; 342 pacientes (Edad media 61,58 ± 13,7 años; 53,5% masculinos). Se encontraron diferencias significativas en todas las variables, antes y después del MAPEC, salvo en sobrepeso/obesidad. Hubo diferencias significativas en el control de la PA, entre MAPEC y No MAPEC (76,72% vs 57,6%; p <0,0001). Entre MAPEC inicio y final, hubo una disminución del promedio de PA sistólica (PAS) de 12,97 mm de Hg; y del promedio de PA diastólica (PAD) de 6,94 mm de Hg. Entre MAPEC final y No MAPEC esta disminución fue de 7,18 mm de Hg y de 1,17 mm de Hg. DISCUSIÓN Hubo diferencias significativas en el control de la PA y las variables analizadas luego de 8 meses de la implementación del MAPEC. Esto se reforzó por el hallazgo de diferencias significativas en la PA controlada con respecto a los CAPS No MAPEC. Los resultados pueden estar influenciados por sesgos y por la pérdida de seguimiento (28%), sin embargo las pruebas estadísticas tuvieron la potencia suficiente para detectar diferencias significativas entre grupos. La implementación del MAPEC fue posible con los recursos de los CAPS y puede constituir un gran aporte para el control de la HTA

Resumen ANTECEDENTES El principal cometido de la citología cervicovaginal es la detección de células malignas seguido del diagnóstico de infecciones cervicovaginales. OBJETIVO Determinar la incidencia de infecciones cervicovaginales diagnosticadas por citología y no tratadas médicamente. MATERIALES Y MÉTODOS Estudio transversal y descriptivo, efectuado en pacientes de una unidad médica de la ciudad de Querétaro, México, con diagnóstico de infección cervicovaginal establecido mediante citología. Parámetros de medición, bacterias detectadas, prescripción o no de tratamiento y seguimiento médico. Para el análisis estadístico se utilizaron intervalos de confianza y el cálculo de la probabilidad de ocurrencia del evento mediante distribución binomial. RESULTADOS En la unidad médica se registraron 260 reportes de citología cervicovaginal. El promedio de gérmenes por reporte de citología fue de 1.9 (IC95%: 1.8-1.9), sobre todo bacterias 98.1% (IC95%: 96.4-99.8). No se entregaron resultados a 81.9% (IC 95%; 77.2-86.6) de las pacientes, ni recibieron tratamiento 84.9% (IC95%; 80.5-89.3). De 10 estudios de citología con resultado de infección cervicovaginal, la probabilidad de que a 3 pacientes no se les entreguen resultados es de 17.5% y que no reciban o se establezca tratamiento de 13.1%. CONCLUSIÓN La incidencia de infecciones cervicovaginales diagnosticadas por citología y no tratadas médicamente es alta.
Abstract BACKGROUND The main objective of cervicovaginal cytology is detection of malignant cells, however it has also proved very useful in the diagnosis of cervicovaginal infections. OBJECTIVE To determine the incidence of cervicovaginal infections diagnosed by cytology and not treated medically. MATERIALS AND METHODS Cross-sectional descriptive study in women with cervicovaginal cytology who reported infection. The sample size was 260 reports, and the sampling technique was randomized systematized. The delivery of the result, the presence of treatment and the follow-up were identified. Statistical analysis included averages, percentages, confidence intervals and calculation of probability of occurrence. RESULTS The average of germs found in each cytology report is 1.9 (95%CI: 1.8-1.9), bacteria are the most frequent germ 98% (95%CI: 96.4-99.8). Results were not given to 81.9% (95%CI: 77.2-86.6) of the population and did not receive treatment in 84.9% (95%CI: 80.5-89.3). In a group of 10 cervicovaginal cytology studies with infection results, the probability that exactly 3 patients will not be given the results is 17.5%, and the probability that exactly 3 patients will not be treated is 13.1%. CONCLUSION The incidence of cervicovaginal infections diagnosed by cytology and untreated medically is high.
RESUMO
BACKGROUND: Acute respiratory infections are the leading cause of mortality in children worldwide, especially in developing countries. Pneumonia accounts for 16% of all deaths of children under 5 years of age and was the cause of death of 935000 children in 2015. Despite its frequency and severity, information regarding its etiology is limited. The aim of this study was to identify respiratory viruses associated with community-acquired pneumonia (CAP) in children younger than 5 years old. METHODS: One thousand four hundred and four children younger than 5 years of age with a clinical and/or radiological diagnosis of CAP in 11 hospitals in Mexico were included. Nasal washes were collected, placed in viral medium, and frozen at -70°C until processing. The first 832 samples were processed using the multiplex Bio-Plex/Luminex system and the remaining 572 samples using the Anyplex multiplex RT-PCR. Clinical data regarding diagnosis, clinical signs and symptoms, radiographic pattern, and risk factors were obtained and recorded. RESULTS: Of the samples tested, 81.6% were positive for viruses. Respiratory syncytial virus (types A and B) was found in 23.7%, human enterovirus/rhinovirus in 16.6%, metapneumovirus in 5.7%, parainfluenza virus (types 1-4) in 5.5%, influenza virus (types A and B) in 3.6%, adenovirus in 2.2%, coronavirus (NL63, OC43, 229E, and HKU1) in 2.2%, and bocavirus in 0.4%. Co-infection with two or more viruses was present in 22.1%; 18.4% of the samples were negative. Using biomass for cooking, daycare attendance, absence of breastfeeding, and co-infections were found to be statistically significant risk factors for the presence of severe pneumonia. CONCLUSIONS: Respiratory syncytial virus (types A and B), human enterovirus/rhinovirus, and metapneumovirus were the respiratory viruses identified most frequently in children younger than 5 years old with CAP. Co-infection was present in an important proportion of the children.

Under natural conditions, Trypanosoma cruzi infection is transmitted to mammals when faeces contaminated with metacyclic trypomastigotes gain access through skin lesions, mucosa or bite wounds. Natural infection of bugs with T. cruzi can vary greatly from less than 1% up to 70%, depending on triatomine species: in the case of Triatoma dimidiata, the percentage of infection is around 30%. In this work uses biological fluids (saliva and faeces) from Triatoma dimidiata to inoculate experimental animals once or multiple times, before inoculation with faeces contaminated with metacyclic trypomastigotes discrete type unit Ia (TcI). The site of infection was analyzed for histological changes based on hematoxile-eosine technique and toluide blue stain for mast cells. Inoculation with saliva led to the recruitment of eosinophils and mononuclear cells at the inoculation site, whereas inoculation with faeces led to the recruitment of neutrophils. Mice inoculated multiple times exhibited a strong inflammatory reaction from the first hour. Mono- or multi-exposure to T. dimidiata fluids before inoculation with metacyclic trypomastigotes helped to control the level of parasitemia. Previous contact with saliva or faeces of T. dimidiata reduces parasitemia in T. cruzi I -infected mice.

Los objetivos de este trabajo fueron definir los trastornos psicopatológicos más comunes asociados a la obesidad y a la desnutrición, así como establecer el grupo de referencia normativo al cual pertenece México en la escala Child Behavior Checklist 6-18 (CBCL/6-18). Este fue un estudio transversal de diseño cuasiexperiemental. Se utilizó la información de 125 niños de escuelas públicas de Ciudad Juárez, Chihuahua, México, en estados de desnutrición, obesidad y normopeso, obtenida mediante las 113 preguntas relacionadas con el comportamiento de niños, que contiene el CBCL 6-18. Por medio de análisis de varianzas se estudiaron las posibles diferencias entre los grupos. Encontramos que nuestra muestra mexicana, pertenece al grupo normativo de referencia tres; las diferencias más significativas se encuentran en el grupo de obesos en la escala de problemas internalizados específicamente en ansiedad/depresión, y en el total de problemas.
This paper sought to define the most common psychopathological disorders associated with obese and malnourished children, and establish the normative group to which Mexico belongs in the Child Behavior Checklist 6-18(CBCL/6-18). This was a cross-sectional study of cuasiexperimental design. CBCL/6-18 data from 125 children from public school in Ciudad Juárez, Chihuahua, México were categorized into obese, malnourished and normal nutrition states. The 113 questions related to the behavior of children of the CBCL 6-18 through variance analysis were used to explore the possible differences between groups. Our Mexican children sample belongs to the normative group three. We found that the major differences were in internalized problems, specifically in anxiety/depression, and on Total Problems with the obese group.

BACKGROUND: Most of the studies characterizing the incidence of rhinovirus (RV) have been carried out in hospitalized children and in developed countries. In those studies, RV-C has been associated with more severe respiratory tract infections than RV species A and B. In this study we determined the frequency and diversity of RV strains associated with upper and lower respiratory tract infections (URTI, LRTI) in Mexico, and describe the clinical characteristics of the illness associated with different RV species. METHODS: A prospective surveillance of 526 and 250 children with URTI and LRTI was carried out. Respiratory samples were analyzed by RT-PCR for viruses. The 5' untranslated region of the RV genome was amplified and sequenced. RESULTS: In the case of URTI, 17.5% were positive for RV, while this virus was found in 24.8% of LRTI. The RV species was determined in 73 children with URTI: 61.6% were RV-A, 37% RV-C and, 1.4% RV-B; and in 43 children with LRTI: 51.2% were RV-A, 41.8% RV-C, and 7% RV-B. No significant differences in clinical characteristics were found in patients with RV-A or RV-C infections. A high genetic diversity of RV strains was found in both URTI and LRTI. CONCLUSIONS: Both RV-A and RV-C species were frequently found in hospitalized as well as in outpatient children. This study underlines the high prevalence and genetic diversity of RV strains in Mexico and the potential severity of disease associated with RV-A and RV-C infections.

Viruses are the most frequent cause of respiratory disease in children. However, despite the advanced diagnostic methods currently in use, in 20 to 50% of respiratory samples a specific pathogen cannot be detected. In this work, we used a metagenomic approach and deep sequencing to examine respiratory samples from children with lower and upper respiratory tract infections that had been previously found negative for 6 bacteria and 15 respiratory viruses by PCR. Nasal washings from 25 children (out of 250) hospitalized with a diagnosis of pneumonia and nasopharyngeal swabs from 46 outpatient children (out of 526) were studied. DNA reads for at least one virus commonly associated to respiratory infections was found in 20 of 25 hospitalized patients, while reads for pathogenic respiratory bacteria were detected in the remaining 5 children. For outpatients, all the samples were pooled into 25 DNA libraries for sequencing. In this case, in 22 of the 25 sequenced libraries at least one respiratory virus was identified, while in all other, but one, pathogenic bacteria were detected. In both patient groups reads for respiratory syncytial virus, coronavirus-OC43, and rhinovirus were identified. In addition, viruses less frequently associated to respiratory infections were also found. Saffold virus was detected in outpatient but not in hospitalized children. Anellovirus, rotavirus, and astrovirus, as well as several animal and plant viruses were detected in both groups. No novel viruses were identified. Adding up the deep sequencing results to the PCR data, 79.2% of 250 hospitalized and 76.6% of 526 ambulatory patients were positive for viruses, and all other children, but one, had pathogenic respiratory bacteria identified. These results suggest that at least in the type of populations studied and with the sampling methods used the odds of finding novel, clinically relevant viruses, in pediatric respiratory infections are low.

OBJETIVO: Construir un modelo que explique la historia natural de proceso diagnóstico del cáncer de mama. MÉTODOS: Estudio transversal descriptivo con 245 de mujeres de 40 a 69 años, seleccionadas mediante muestreo aleatorio simple a quienes se realizó una mastografía y cumplieron con los principios del proceso diagnóstico de cáncer de mama. El diagnóstico se realizó por biopsia. Para el proceso diagnóstico se estimaron el porcentaje de pacientes atendidas en cada servicio, el total de pacientes por servicio y el total de consultas generadas en cada servicio y sus intervalos de confianza de 95%. RESULTADOS: A 20% de las pacientes que iniciaron el proceso diagnóstico del cáncer de mama en medicina preventiva se le realizó una mastografía, 23,7% fue atendido en medicina familiar, de ellas, 70,9% se derivó a la clínica de mama y a 7,3% se le realizó biopsia con arpón. La prevalencia de cáncer de mama confirmada mediante biopsia fue 0,48% (IC95%: 0,0-1.3). Por cada 1 000 pacientes que iniciaron el proceso, 47,4 se atienden en medicina familiar, 33,6 en clínica de mama y a 2,4 se les realiza biopsia abierta. Por cada 1 000 pacientes que entran en dicho proceso, se generan 211,4 consultas en radiología, 51,6 en medicina familiar y 54,6, en la clínica de mama. CONCLUSIONES: El modelo descrito puede ser útil en actividades de planificación y evaluación.
OBJECTIVE: To build a model that explains the natural history of breast cancer diagnostic procedures. METHODS: Descriptive cross-sectional study of 245 women between 40 and 69 years of age, selected by simple random sampling, who underwent a mammography and met the requirements of the breast cancer diagnostic procedure. Diagnosis was made by biopsy. For the diagnostic procedure, an estimate was made of the percentage of patients seen by each service, the total number of patients per service, and the total number of consultations in each service, with 95% confidence intervals. RESULTS: Of the patients who initiated the breast cancer diagnostic procedure in preventive medicine services, 20% underwent a mammography; 23.7% were seen in family medicine services and of these patients, 70.9% were referred to a breast clinic, where 7.3% underwent a harpoon biopsy. The prevalence of breast cancer confirmed by biopsy was 0.48% (95%CI: 0.0-1.3). Per 1 000 patients who initiated the procedure, 47.4 were seen in family medicine services and 33.6 in a breast clinic, and open biopsies were performed on 2.4. Per 1 000 patients who initiated the procedure, there were 211.4 consultations in radiology services, 51.6 in family medicine services, and 54.6 in a breast clinic. CONCLUSIONS: The model described here may be useful in planning and evaluation activities.

It has been shown that supplementation with omega-3 improves cognitive performance, especially in infants and toddlers, but it is unknown whether these results are effective in older malnourished children. The aims of this study, therefore, were to investigate the omega-3 supplementation effects in 8- to 12-year-old children and to know which neuropsychological functions improve after three months of intervention in a sample of Mexican children with mild to moderate malnutrition. This study was a randomized, double-blind, treatment and placebo study of 59 children aged 8-12 years who were individually allocated to 2 groups. The duration of the intervention lasted 3 months. Neuropsychological performance was measured at baseline and at 3 months. Results show that more than 50% of children in the treatment group had greater improvement in 11 of the 18 neuropsychological variables studied. Processing speed, visual-motor coordination, perceptual integration, attention and executive function showed improvement in more than 70% of the omega-3 supplemented children. This trial was registered at clinicaltrials.gov as NCT01199120.

INTRODUCTION: Diabetes Mellitus (DM) type 2 is a common pathology with multifactorial etiology, which exact genetic bases remain unknown. Some studies suggest that single nucleotides polymorphisms (SNPs) in the CAPN10 gene (Locus 2q37.3) could be associated with the development of this disease, including the insertion/deletion polymorphism SNP-19 (2Râ3R). OBJECTIVE: The present study determined the association between the SNP-19 and the risk of developing DM type 2 in Ciudad Juarez population. METHODOLOGY: For this study 107 participants were selected: 43 diabetics type 2 (cases) and 64 non diabetics with no family history of DM type 2 in first grade (control). Anthropometric studies were realized as well as lipids, lipoproteins and serum glucose biochemical profiles. The genotypification of SNP-19 was performed using peripheral blood lymphocytes DNA, polymerase chain reactions (PCR), and electrophoretic analysis in agarose gels. Once obtained the genotypic and allelic frequencies, the Hardy-Weinberg equilibrium test (GenAlEx 6.4) was also performed. RESULTS: Using the X² analysis it was identified the genotypic differences between cases and control with higher frequency of the homozygous genotype 3R of SNP- 19 in the cases group (0.418) compared to control group (0.265). Also, it was observed an association between genotype 2R/3R with elevated weight, body mass index, and waist and hip circumferences, but only in the diabetic group (P=< 0.05). CONCLUSION: The findings in this study suggest that SNP-19 in CAPN10 may participate in the development of DM type 2 in the studied population.
Introducción: La diabetes mellitus (DM) tipo 2 es una patología común de origen multifactorial cuyas bases genéticas exactas se desconocen aún; diversos estudios sugieren que los polimorfismos de nucleótido único (SNPs) en el gen CAPN10 (Locus 2q37.3) podrían participar en su desarrollo, incluyendo el polimorfismo de inserción/ deleción SNP-19 (2Râ3R). Objetivo: Determinar la relación entre el polimorfismo SNP-19 y la presencia de DM tipo 2 en una población de Ciudad Juárez. Métodos: Se seleccionaron 107 individuos: 43 diabéticos tipo 2 (casos) y 64 no diabéticos sin antecedentes heredo-familiares de DM tipo 2 en primer grado (control). Se realizó estudio antropométrico y perfil bioquímico de lípidos, lipoproteínas y glucosa sérica. Se extrajo ADN de linfocitos de sangre periférica y se amplificó mediante la técnica de reacción en cadena de la polimerasa (PCR). Se analizaron los genotipos del polimorfismo SNP-19 del gen CAPN10 por análisis electroforético en geles de agarosa. Se calcularon las frecuencias genotípicas y alélicas y se realizaron pruebas de equilibrio de Hardy-Weinberg (GenAlEx 6.4). Resultados: El análisis mediante la prueba X² identificó diferencias en los genotipos entre casos y control, con una mayor frecuencia del genotipo homocigoto 3R del SNP-19 en el grupo de casos (0.418) respecto al grupo control (0.265). El genotipo 2R/3R presentó relación con valores elevados de peso, índice de masa corporal y perímetros de cintura y cadera; pero solo en el grupo de diabéticos (P=< 0.05). Conclusión: Los resultados de esta investigación sugieren la participación del SNP-19 del gen CAPN10 en el desarrollo de DM tipo 2 en la población estudiada.
