Myocardial Strain for the Differentiation of Myocardial Involvement in the Post-Acute Sequelae of COVID-19-A Multiparametric Cardiac MRI Study.

Myocardial involvement was shown to be associated with an unfavorable prognosis in patients with COVID-19, which could lead to fatal outcomes as in myocardial injury-induced arrhythmias and sudden cardiac death. We hypothesized that magnetic resonance imaging (MRI) myocardial strain parameters are sensitive markers for identifying subclinical cardiac dysfunction associated with myocardial involvement in the post-acute sequelae of COVID-19 (PASC). This study evaluated 115 subjects, including 65 consecutive COVID-19 patients, using MRI for the assessment of either post-COVID-19 myocarditis or other cardiomyopathies. Subjects were categorized, based on the results of the MRI exams, as having either 'suspected' or 'excluded' myocarditis. A control group of 50 matched individuals was studied. Along with parameters of global cardiac function, the MRI images were analyzed for measurements of the myocardial T1, T2, extracellular volume (ECV), strain, and strain rate. Based on the MRI late gadolinium enhancement and T1/T2/ECV mappings, myocarditis was suspected in 7 out of 22 patients referred due to concern of myocarditis and in 9 out of 43 patients referred due to concern of cardiomyopathies. The myocardial global longitudinal, circumferential, and radial strains and strain rates in the suspected myocarditis group were significantly smaller than those in the excluded myocarditis group, which in turn were significantly smaller than those in the control group. The results showed significant correlations between the strain, strain rate, and global cardiac function parameters. In conclusion, this study emphasizes the value of multiparametric MRI for differentiating patients with myocardial involvement in the PASC based on changes in the myocardial contractility pattern and tissue structure.

Effect of Self-transcendence, Self-distancing, and Family Functionality on Self-care Agency in Older Adults.

Objective: To determine the effect of self-distancing, self-transcendence, and family functioning on self-care agency in Mexican older adults. Methods: Correlational-explanatory design, with a sample of 253 elderly, collecting data through a simple random sampling. A personal data questionnaire was applied, the scale of: self-transcendence, the self-distancing subscale, the family APGAR and the ability to self-care in Mexican population from different demographic groups. Descriptive and inferential statistics were applied (Mann-Whitney U and a structural equation model) and the study was approved by a registered ethics committee. Results: The study had participation from 253 elderly, with a mean age of 68.02 years, with prevalence of the female sex (60.1%); the level of education was primary school or lower (51.4%). It was observed that the group of chronic diseases had lower self-distancing (U = 4.449.5, p = 0.038) and greater self-transcendence (U = 4177.0, p = 0.008), and selfcare (U = 4365.5, p = 0.024) than the group without chronic diseases. It was also found that self-transcendence, self-distancing, and family functionality produce a positive effect of 37% on selfcare. Conclusion: Self-distancing, self-transcendence, and family functionality explain an important proportion of selfcare in the elderly. Said knowledge permits understanding the care behavior of the elderly and, thus, propose future educational interventions by nursing to prevent or avoid functional, cognitive loss and social effects.

Real-Time Strain-Encoding Cardiovascular MRI for Assessment of Regional Heart Function in Tetralogy of Fallot Patients.

BACKGROUND: Tetralogy of Fallot (ToF) is the most common form of cyanotic congenital heart disease, where right ventricular (RV) function is an important determinant of subsequent intervention. OBJECTIVE: In this study, we evaluate the feasibility of fast strain-encoding (fastSENC; a one-heartbeat sequence) magnetic resonance imaging (MRI) for assessing regional cardiac function in ToF. METHOD: FastSENC was implemented to characterize regional circumferential (Ecc) and longitudinal (Ell) strains in the left ventricle (LV) and RV in post-repair ToF. Data analysis was conducted to compare strain measurements in the RV to those in the LV, as well as to those generated by the MRI Tissue-Tracking (MRI-TT) technique, and to assess the relationship between strain and ejection fraction (EF). RESULTS: Despite normal LVEF (55±8.5%), RVEF was borderline (46±6.4%), but significantly lower than LVEF. RV strains (RV-Ell=-20.2±2.9%, RV-Ecc=-15.7±6.4%) were less than LV strains (LV-Ell=-21.7±3.7%, LV-Ecc=-18.3±4.7%), and Ell was the dominant strain component. Strain differences between fastSENC and MRI-TT were less significant in RV than in LV. There existed moderate and weak correlations for RV-Ecc and RV-Ell, respectively, against RVEF. Compared to LV strain, RV strain showed regional heterogeneity with a trend for reduced strain from the inferior to anterior regions. Inter-ventricular strain delay was larger for Ell (64±47ms) compared to Ecc (36±40ms), reflecting a trend for contraction dyssynchrony. CONCLUSION: FastSENC allows for characterizing subclinical regional RV dysfunction in ToF. Due to its sensitivity for evaluating regional myocardial contractility patterns and real-time imaging capability without the need for breath-holding, fastSENC makes it more suitable for evaluating RV function in ToF.

Myocardial Contractility Pattern Characterization in Radiation-Induced Cardiotoxicity Using Magnetic Resonance Imaging: A Pilot Study with ContractiX.

Radiation therapy (RT) plays an integral role in treating thoracic cancers, despite the risk of radiation-induced cardiotoxicity. We hypothesize that our newly developed magnetic resonance imaging (MRI)-based contractility index (ContractiX) is a sensitive marker for early detection of RT-induced cardiotoxicity in a preclinical rat model of thoracic cancer RT. Adult salt-sensitive rats received image-guided heart RT and were imaged with MRI at 8 weeks and 10 weeks post-RT or sham. The MRI exam included cine and tagging sequences to measure left-ventricular ejection fraction (LVEF), mass, myocardial strain, and ContractiX. Furthermore, ventricular torsion, diastolic strain rate, and mechanical dyssynchrony were measured. Statistical analyses were performed between the sham, 8 weeks post-RT, and 10 weeks post-RT MRI parameters. The results showed that both LVEF and myocardial mass increased post-RT. Peak systolic strain and ContractiX significantly decreased post-RT, with a more relative reduction in ContractiX compared to strain. ContractiX showed an inverse nonlinear relationship with LVEF and continuously decreased with time post-RT. While early diastolic strain rate and mechanical dyssynchrony significantly changed post-RT, ventricular torsion changes were not significant post-RT. In conclusion, ContractiX measured via non-contrast MRI is a sensitive early marker for the detection of subclinical cardiac dysfunction post-RT, and it is superior to other MRI cardiac measures.

Methicillin-resistant S. aureus colonization in Mexican children attending day care centres.

PURPOSE: To determine MRSA carriage rates and genetic relationships of S. aureus strains in children attending day care centres in 14 cities from three geographic regions in Mexico. MATERIALS AND METHODS: Cross-Sectional Study performed in apparently healthy children aged from 6 mo to 6 yr attending day care centres (DCCs). From September 2002 To January 2003, 2345 nasopharyngeal specimens from a similar number of children were collected. Nasopharyngeal samples for bacterial isolation were obtained by standard methods. Antimicrobial susceptibility was determined and genetic relatedness of all MRSA isolates was determined by pulsed field gel electrophoresis (PFGE). RESULTS: S. aureus was identified in 237 children (10.1%), twenty-two children had MSRA for an overall prevalence of MRSA carriage of 0.93%. Children attending DCCs from cities located in the north and south of Mexico showed higher prevalence than children from DCCs in the central region; 1.75%, and 1.71 vs. 0.08%, respectively (P < 0.05). PFGE demonstrated six different restriction profiles of MRSA with a predominant pattern. CONCLUSIONS: We documented the presence of MRSA strain colonizing children attending DCCs in Mexico, mainly in the south and north regions of the country. Clone A and B which are closely related represented 45 % of the total of MRSA isolates. We found both, SCCmec type II and type IV strains in the three regions.

Las barreras de autocuidado y el empoderamiento de la diabetes tipo 2 en adultos mexicanos: un modelo estructural / Self-care barriers and the empowerment of type 2 diabetes in mexican adults: a structural model

RESUMEN Objetivo: Explicar el efecto de las barreras de autocuidado sobre el empoderamiento de la enfermedad en adultos con diabetes. Método: Diseño correlacional-explicativo, recolectado mediante muestreo a conveniencia en 657 adultos con diabetes. Se empleó una cédula de datos personales, la escala de Barreras de Autocuidado (α =0.78) y la escala de Empoderamiento en Diabetes (α=0.89). Se aplicó el consentimiento informado y requerimientos legales para la investigación. Se utilizó estadística descriptiva, al igual que estadística inferencial como la prueba de Spearman y un modelo de ecuaciones estructurales. Resultados: Los participantes tuvieron una M=50.10 años, siendo la mayoría mujer (58.9 %) y adulto maduro (37.6 %). El 56.5 % no tiene empoderamiento en diabetes y tuvo una M=82.12 en las barreras de autocuidado. El empoderamiento se relaciona con la edad (r=-0.199), los años de vivir con diabetes (r=-0.097) y con las barreras de autocuidado (r=0.302). Aunado, ambas se explican (- 0.34). Los indicadores de bondad fueron %2= 35.309 (8 g.l.), p<.0001, X2 relativa= 4.41, y al igual los indicadores prácticos fueron de BBNFI=.99, BBNNFI=.98, CFI=.99 y el RMSEA= .07, explicando el 12 % de la varianza de empoderamiento de la diabetes. Conclusión: Se confirma mediante el modelo de ecuaciones estructurales que las barreras de autocuidado influyen positiva y significativamente en un 12 % sobre el empoderamiento de la diabetes.

ABSTRACT Objective: To explain the effect of self-care barriers on disease empowerment in adults with diabetes. Method: Correlational-explanatory design, collected by convenient sampling in 657 adults with diabetes. We used a personal data card, the Self-Care Barriers Scale (α =0.78), and the Diabetes Empowerment Scale (α =0.89). Informed consent and legal requirements for the investigation were applied. Descriptive statistics were used, as well as inferential statistics such as the Spearman test and a model of structural equations. Results: Participants had an M=50.10 years, the majority being female (58.9%) and mature adult (37.6%). 56.5% have no empowerment in diabetes and had an M=82.12 in self-care barriers. Empowerment is related to age (r=-0,199), years of living with diabetes (r=-0,097), and barriers to self-care (r=0,302). Together, both are explained (- 0.34). The indicators of goodness were X2= 35,309 (8 g.l.), p<.0001, X2 relative= 4.41, and the practical indicators were BBNFI=.99, BBNFI=.98, CFI=.99, and RMSEA=.07, explaining 12% of the variance of diabetes empowerment. Conclusion: It is confirmed by the model of structural equations that self-care barriers positively and significantly influence 12% on the empowerment of diabetes.

Resistance of uropathogenic bacteria to first-line antibiotics in mexico city: A multicenter susceptibility analysis.

UNLABELLED: Abstract. BACKGROUND: Growing antibiotic resistance demands the constant reassessment of antimicrobial efficacy, particularly in countries with wide antibiotic abuse, where higher resistance prevalence is often found. Knowledge of resistance trends is particularly important when prescribing antibiotics empirically, as is usually the case for urinary tract infections (UTIs). Currently, in Mexico City, ampicillin, cotrimoxazole (trimethoprim/sulfamethoxazole), and ciprofloxacin are used as "first-line" antibiotic treatment for UTI. OBJECTIVE: The aim of this study was to analyze the resistance of bacterial isolates to antibiotics, with a focus on first-line antibiotics, in Mexican pediatric patients and sexually active or pregnant female outpatients. METHODS: In this multicenter susceptibility analysis, bacterial isolates from urine samples collected from pediatric patients and sexually-active or pregnant female outpatients presenting with acute, uncomplicated UTIs in Mexico City from January 2006 through June 2006, were included in the study. Samples were tested for susceptibility to 10 antibiotics by the disk-diffusion method. RESULTS: Four-hundred and seventeen bacterial isolates were derived from sexually active or pregnant female outpatients (324 Escherichia coli) and pediatric patients (93 Klebsiella pneumoniae). We found a high prevalence of resistance towards the drugs used as "first-line" when treating UTIs: ampicillin, cotrimoxazole, and ciprofloxacin (79%, 60%, and 24% resistance, respectively). Ninety-eight percent of K pneumoniae isolates were resistant to ampicillin, whereas 66% of the E coli isolates were resistant to cotrimoxazole. Resistance towards third-generation cephalosporins was also high (6%-8% of E coli and 10%-28% of K pneumoniae). This was possibly caused by chromosomal ß-lactamases, as 30% of all isolates were also resistant to amoxicillin/clavulanate. In contrast, 98% of the E coli isolates and 84% of the K pneumoniae strains (96% of all isolates) were found to be susceptible to nitrofurantoin, which has been in clinical use for much longer than most other drugs in this study. CONCLUSION: In these urine samples from laboratories in Mexico City, resistance of K pneumoniae and E coli isolates to first-line treatment (ampicillin, cotrimoxazole, or ciprofloxacin) of UTI was high, whereas most E coli and K pneumoniae isolates were susceptible to nitrofurantoin and the fourth-generation cephalosporin cefepime.

El riesgo para pie diabético se relacionó con las barreras de autocuidado en diabetes (r=.224, p<0.5) y el índice de masa corporal (r=.255, p<0.5). El modelo predice un 19.6 % el riesgo (F=6.803, R 2 =19.6, p=0.001), siendo las variables predictoras las barreras de autocuidado en diabetes, el colesterol de baja densidad y el índice de masa corporal. Conclusión: Los factores conductuales y biológicos predicen el aumento del riesgo para pie diabético, por lo que nos da una valoración general de salud de los grupos de ayuda mutua de México.

Objective. To determine the influence of behavioral and biological agents on the risk for diabetic foot in adult stages of pre and old age who attend mutual aid groups. Material and methods: Correlational-predictive, with a sample of 105 people collected by convenience in mutual aid groups from three counties of Coahuila, Mexico. A personal data card, the IMEVID instrument (α = .81), the EBADE scale (α = .78), the collection of anthropometric measurements, metabolic biomarkers were applied and the risk assessment for diabetic foot was performed. Descriptive statistics, spearman correlation and regression models were applied. Results: 87 (82.9%) women and 18 (17.1%) men participated with an M = 62.60 years (SD = 10,330) years. The risk for diabetic foot was related to the barriers to self-care in diabetes (r = .224, p <0.5) and the body mass index (r = .255, p <0.5). The model predicts the risk of 19.6% (F = 6.803, R2 = 19.6, p = 0.001), the predictor variables being the barriers to self-care in diabetes, low-density cholesterol and the body mass index. Conclution: Behavioral and biological factors predict the increased risk for diabetic foot, so it gives us a general assessment of the health of mutual aid groups in Mexico.

Comportamiento planificado para la práctica de ejercicio físico en un adulto mayor en tiempos de COVID-19 / Planned Exercise Behavior in an Older Adult in Times of COVID-19

Introducción: El cuerpo del ser humano está creado para estar en activación constante. Sin embargo, las conductas sedentarias en las personas adultas mayores son cada vez más comunes. Lo anterior es preocupante, ya que este grupo etario tiene la creencia de que al llegar a esa etapa de su vida no se debe realizar ejercicio físico, a pesar de que esta necesidad no disminuye con el paso de los años. Objetivo: Describir las vivencias del comportamiento planificado para la práctica de ejercicio físico en un adulto mayor durante la pandemia de la COVID-19. Métodos: Estudio de caso único con abordaje fenomenológico, el referente utilizado fue la fenomenología de la percepción de Maurice Merleau-Ponty, bajo la perspectiva de la teoría comportamiento planificado. Se realizó una entrevista a profundidad. Para el análisis cualitativo de la información se utilizó el referente propuesto por Taylor-Bogdan. Resultados: Se obtuvieron tres categorías y ocho subcategorías, se definieron con base al fenómeno de estudio seleccionado, la teoría del comportamiento planificado: Experiencia al ejercicio; Control percibido; Norma subjetiva. Conclusiones: La experiencia de practicar ejercicio físico en la vejez es vivida con una actitud positiva; sin embargo, esta se tornó negativa, porque debido a la pandemia por COVID-19 fue obligatorio interactuar a través de la tecnología para poder realizar ejercicio físico(AU)

Introduction: The human body is created to be in constant activation. However, sedentary behaviors in older adults are increasingly common. This is worrisome, since this age group has the belief that when they reach this stage of their life they should not do physical exercise, even though this need does not diminish with the passing of the years. Objective: To describe the experiences of planned physical exercise behavior in an older adult during the COVID-19 pandemic. Methods: Single case study with phenomenological approach, the reference used was Maurice Merleau-Ponty's phenomenology of perception, under the perspective of the planned behavior theory. An in-depth interview was conducted. For the qualitative analysis of the information, the referent proposed by Taylor-Bogdan was used. Results: Three categories and eight subcategories were obtained, they were defined based on the selected study phenomenon, the theory of planned behavior: experience to exercise; perceived control; subjective norm. Conclusions: The experience of practicing physical exercise in old age is lived with a positive attitude; however, this became negative, because due to the pandemic by COVID 19 it was mandatory to interact through technology to be able to perform physical exercise(AU)

Objetivo: Determinar los factores de riesgo de bronquiolitis en menores de dos años que consultaron al servicio de Pediatría del Instituto de Medicina Tropical entre el 2018 y 2019. Método: Estudio de tipo descriptivo, transversal en el que se incluyeron pacientes menores de 2 años internados en el Servicio de Pediatría del Instituto de Medicina Tropical de enero de 2018 a febrero de 2019 con diagnóstico de bronquiolitis en el que se analizaron los factores de riesgo de la enfermedad. Resultados: Se estudió una población de 38 pacientes que presentaron bronquiolitis antes de los 2 años, 19 fueron niños (50%) La edad media al ingreso fue de 3,5 ± 2,8 meses (límites, 1-10 meses). No se han encontrado datos de tabaco en el embarazo. Se detectó VRS en el aspirado nasofaríngeo de 8 niños (21%), la detección viral fue negativa en 14 niños (37%) y no se realizó la determinación en 18 casos (47%). Los siguientes factores de riesgo se asociaron de forma independiente con la bronquiolitis: Asma de los padres, infección por VSR, sibilancia, cianosis y hacinamiento. Los factores de riesgo estudiado, exposición al tabaco, sexo, edad en el momento de la bronquiolitis o lactancia materna exclusiva, no se asociaron con el ingreso a UTI de los pacientes con bronquiolitis. Conclusión: Hemos encontrado factores de riesgo asociado relacionados al huésped como asma de los padres, y otros como sibilancia, cianosis, hacinamiento e infección por VRS.

Abstract Introduction: It is estimated that globally, each year around 10% of infants have bronchiolitis. A peak occurs between 2 and 6 months of age Objective: To determine the risk factors of bronchiolitis in children less than two years of age who admitted at the pediatric service of the Institute of Tropical Medicine between 2017 and 2019 Method: A descriptive, cross-sectional study in which patients under 2 years of age admitted to the Pediatric Service of the Institute of Tropical Medicine from January 2018 to February 2019 were included with a diagnosis of bronchiolitis in which the risk factors of the disease were analyzed. Results: We studied a population of 38 patients who presented bronchiolitis before 2 years, 19 were children (50%) The average age at admission was 3.5 ± 2.8 months (range, 1-10 months). No tobacco data were found in pregnancy. RSV was detected in the nasopharyngeal aspirate of 8 children (21%), viral detection was negative in 14 children (37%) and the determination was not made in 18 cases (47%). The following risk factors were independently associated with bronchiolitis: Asthma of the parents, RSV infection, wheezing, cyanosis and overcrowding. The risk factors studied exposure to tobacco, sex, age at the time of bronchiolitis or exclusive breastfeeding were not associated with admission to the ICU of patients with bronchiolitis. Conclusion: We have found associated risk factors related to the host such as asthma of the parents, and others such as wheezing, cyanosis, overcrowding and RSV infection.

The sensitivity of antigenemia testing was excellent and similar in all age groups.

Cost-effectiveness analysis of pneumococcal conjugate vaccine introduction in Paraguay.

OBJECTIVE: To describe a cost-effectiveness analysis of 10- or 13-valent pneumococcal conjugate vaccine (PCV10 or 13) introduction in Paraguay compared to no vaccination. METHODS: The integrated TRIVAC vaccine cost-effectiveness model (version 2.0) jointly developed by the Pan American Health Organization's ProVac Initiative and the London School of Hygiene & Tropical Medicine was applied from the government and societal perspectives to estimate the cost-effectiveness (CE) of PCV introduction during 2010 and 2011. The cost-effectiveness ratios of PCV10 and PCV13 were separately compared to non-vaccination. The model calculated health and economic benefits of vaccination for 10 birth cohorts of children <5 years of age. A base case scenario with two primary doses at 2 and 4 months and a booster dose at 12 months (2+1 schedule) and alternate scenarios with varying parameters were considered. RESULTS: With PCV10 introduction, the incremental costs of the vaccination program would be approximately US$ 67 million to vaccinate all 10 cohorts of children; with PCV13, US$ 87 million. Health services costs avoided by the government with PCV10 would be US$ 19.5 million; with PCV 13, US$ 17.7 million. From the societal perspective, savings were much greater: with PCV10, US$ 43 million; with PCV13, US$ 35 million. For the higher priced PCV13, the average cost-effectiveness ratio was better than for PCV10 when compared to no vaccination, but regardless both were cost effective for government and society based on a threshold of 3× GDP per capita in Paraguay (2009 US$ 2516). The number of averted meningitis and all-cause pneumonia cases and deaths was greater with PCV13 than with PCV10 when compared to no vaccination. CONCLUSION: The introduction of either PCV10 or PCV13 would be cost effective when compared to no vaccination, and in some scenarios, highly cost effective in Paraguay. The outcomes of these analyses demonstrate that a pneumococcal vaccine could substantially reduce morbidity and mortality in children <5 years in Paraguay.

Análisis confirmatorio de la Escala de Autoevaluación Breve de Bienestar y Autonomía en Adultos Mayores de Coahuila y Yucatán, México / Confirmatory Analysis of the Short Self-Assessment of Wellbeing and Autonomy Scale in Older Adults in Coahuila and Yucatán, Mexico

Resumen El objetivo de este trabajo fue realizar un Análisis Factorial Confirmatorio de la Escala de Bienestar y Autonomía específica para adultos mayores en dos muestras mexicanas, lo que permitió determinar la validez del constructo medido. Se utilizó un diseño cuantitativo, transversal con alcances explicativos. Se analizó una muestra incidental de 895 adultos mayores, de los cuales 59.8 % eran habitantes de la ciudad de Saltillo, Coahuila, México y 40.2 % de Tizimín, Yucatán, México. Se utilizó la Escala de Autoevaluación Breve de Bienestar y Autonomía para Adultos Mayores. Se procesó el Análisis Factorial Exploratorio, Paralelo y Confirmatorio con el método de Mínimos Cuadrados Generalizados, además de obtener la confiabilidad y los estadísticos descriptivos de las dimensiones. La estructura que se identificó presentó indicadores de ajuste estadístico adecuado. Originalmente, la estructura consideraba dos dimensiones: la autonomía y el bienestar, sin embargo, los resultados mostraron la separación en tres dimensiones de la medición de bienestar.

Abstract The objective of this work was to carry out a Confirmatory Factorial Analysis of the Scale of Wellbeing and Specific Autonomy for Older Adults in two Mexican samples, which allowed to establish the validity of the measured construct. A quantitative, transversal design with explanatory scopes was used. An incidental sample of 895 aging adults was obtained, from which 59.8% were inhabitants of the Saltillo city, Coahuila, Mexico, and 40.2%, of Tizimín city, Yucatán, Mexico. We used the Short SelfAssessment of Wellbeing and Autonomy for Older Adults. The Exploratory, Parallel and Confirmatory Factor Analysis was processed with the Generalized Least Squares Method, in addition to obtaining the reliability and descriptive statistics of dimensions. The identified structure showed adequate statistical adjustment indicators. Initially, the structure considered two dimensions: autonomy and wellbeing; however, the results showed the separation in three dimensions of the wellbeing measurement.

Riesgo de diabetes de una comunidad rural en México: un estudio observacional / Diabetes Risk in a Rural Community in Mexico: an Observational Study

Introducción. La rápida transición del medio rural a la adopción de hábitos alimenticios de zonas urbanas, el sedentarismo, las dificultades de acceso a la salud, ponen a la población en mayor riesgo de desarrollo de diabetes, sin embargo, son pocos los estudios que se enfocan en este fenómeno a nivel rural. Conocer el riesgo permite identificar las áreas problemáticas y revertir la situación a través de modelos de atención para esta población. El objetivo de este estudio fue describir los factores de riesgo presentes en una comunidad rural de Guanajuato. Material y Métodos: Estudio descriptivo, observacional, transversal; muestra no probabilística de 164 personas sin diabetes, se calculó con Epidat 3.1, intervalo de confianza al 95%, precisión del 3%; se aplicó el Cuestionario de Factores de Riesgo para la Diabetes Mellitus. Para la colecta se hizo un recorrido de casa por casa hasta completar la muestra, para el análisis estadístico se utilizó la chi cuadrada y cálculo de odds ratio. Resultados: El 71%(117) de la población fueron mujeres; el promedio para la edad fue de 43 años; el 85% de los sujetos presentaron un alto riesgo de padecer diabetes; los tres principales factores de riesgo fueron: 57.9% (95) con sobrepeso y obesidad, el 77.4%(127) de la muestra con cintura superior al parámetro recomendado, 75.6% (124) de la muestra presentó antecedentes heredofamiliares; en cuestión de género las mujeres presentaron 3 veces más riesgo de diabetes (p=<.05). Conclusión: Los entornos rurales muy contrario a lo que se observaba, tienen alto riesgo de desarrollo de diabetes, probablemente va de la mano con los cambios de hábitos de las comunidades, pues la industrialización las ha invadido, con todo lo que conlleva, como lo señala Moreno L

Un enfoque cualitativo a las barreras de adherencia terapéutica en enfermos crónicos de Guanajuato, México / A Qualitative Approach to Barriers to Adherence to Therapy among the Chronically Ill in Guanajuato, Mexico / Um enfoque qualitativo nas barreiras de adesão terapêutica em doentes crônicos de Guanajuato, México

Introducción: el perfil epidemiológico en México está dominado por enfermedades crónico-degenerativas y lesiones, estas a su vez están asociadas a las condiciones de vida actual. La OPS y la OMS aconsejan el estudio de barreras que impiden la atención de calidad. Objetivo: explorar la percepción de las barreras personales y sociales hacia el tratamiento de personas con estados crónicos: diabetes e hipertensión. Materiales y métodos: estudio cualitativo, con un componente descriptivo. La muestra estuvo conformada por diabéticos e hipertensos de colonias marginales. Muestreo de tipo intencional. La recolección de la información se realizó por medio de entrevistas semiestructuradas y audio-grabadas. Se trabajó con 3 grupos focales de 3 personas por grupo. Un 77% casado, 77% analfabeta, 77% labores del hogar, 56% diabéticos tipo 2,22% hipertensos, 22% diabéticos con hipertensión. Las barreras percibidas encontradas fueron: creencias relacionadas con el tratamiento, falta de conocimientos y habilidades para la dieta, descontento con la dieta, falta de apoyo familiar, dificultades económicas, falta de conocimientos sobre la medicación, indiferencia hacia el ejercicio, desconfianza y temor a los estudios de laboratorio. Discusión y conclusión: para Rosentock, en tanto que las claves para la acción incitan a las actividades preventivas para la salud, las barreras percibidas indican los caminos para la acción. Es necesario superar barreras y ayudar al enfermo crónico a convivir con la enfermedad.

Introduction: The epidemiological profile in Mexico is dominated by chronic degenerative diseases and injuries. These, in turn, are associated with current living conditions. PAHO and WHO recommend the study of barriers to quality care. Objective: The purpose of this research was to explore the perception of personal and social barriers to treatment for persons with chronic illnesses; namely, diabetes and hypertension. Materials and methods: This is a qualitative study with a descriptive component. The sample was comprised of diabetics and hypertensive persons from low-income neighborhoods. Intentional sampling was used. The data were collected through semistructured interviews that were audio-recorded. Work was done with three focus groups of three people each: 77% were married, 77% were illiterate, 77% were homemakers, 56% had type II diabetes, 22% were hypertensive and 22% were diabetics with hypertension. The perceived barriers revealed by the study include treatment-related beliefs, lack of knowledge and skill to pursue the recommended diet, dissatisfaction with the diet, lack of family support, economic hardship, lack of knowledge about the medication, indifference to exercise, and distrust and fear of laboratory exams. Conclusion: For Rosentock, whereas the keys to action encourage preventive activities with respect to health, the perceived barriers signal the path to action. Barriers must be overcome and the chronically ill must receive help to live with their conditions.
