RESUMEN
Resumen Introducción: Evaluar la empatía es cada vez más necesario dentro de diferentes áreas de investigación. Objetivo: El presente estudio presenta un análisis de las propiedades psicométricas del cuestionario Test de Empatía Cognitiva y Afectiva (TECA) que evalúa la empatía desde una perspectiva integral; siendo uno de los pocos construidos originalmente en el lenguaje español. Método: Sé evaluó la fiabilidad y validez de constructo en 607 adultos (137 hombres/ 470 mujeres) estudiantes de población mexicana. Resultados: Los resultados muestran una adecuada fiabilidad del instrumento en general (α = .86). Sin embargo, los análisis factoriales exploratorios y confirmatorios sugiere la necesidad de revisar los ítems. Discusión: La incorporación de metodologías robustas que consideran la naturaleza ordinal de las escalas Likert, como el análisis factorial con la incorporación del intercepto aleatorio permiten mejorar el ajuste de los modelos sin alterar la estructura factorial original. Por último, la invariancia métrica no es alcanzada entre la muestra española original y la mexicana. Conclusiones: El TECA se puede aplicar en población mexicana pero se sugiere una revisión en la construcción de los ítems.
Abstract Introduction: Assessing empathy is an increasing necessity within different research areas. Objective: The present study aims to analyse psychometric properties of the Cognitive and Affective Empathy Test (TECA) questionnaire that assesses empathy from a comprehensive perspective; being one of the few originally built in the Spanish language. Method: The reliability and construct validity were evaluated in 607 adults (137 men / 470 women) students from the Mexican population. Results: The results show adequate reliability of the instrument in general (α = .86). However, the exploratory and confirmatory factor analyzes suggest the need to review the items. Discussion: The incorporation of new methodologies such as robust factor analysis for ordinal type data (i.e. like Likert scales), with the incorporation of the random intercept, allows improving the fit of the models without altering the original factorial structure. Finally, metric invariance is not reached between the original Spanish sample and the Mexican one. Conclusions: The TECA can be applied in the Mexican population but a review of the construction of the items is suggested.
RESUMEN
The authors would like to update some important data in the manuscript. In Table 4, the pesticide means were reported in µg/mL, which is incorrect. The correct units are ng/mL (nanograms/milliliter). The same typographical inaccuracy applies for data in the fourth paragraph of the discussion (with minimal values of 0.0020 µg/mL and maximal values of 2.63 µg/mL), where the correct units are also ng/mL [1].

RESUMEN
The use of pesticides in agricultural activities has increased significantly during the last decades. Several studies have reported the health damage that results from exposure to pesticides. In Mexico, hundreds of communities depend economically on agricultural activities. The participation of minors in this type of activity and their exposure to pesticides represents a potential public health problem. A cross-sectional study was conducted, in which urine samples (first-morning urine) were taken from children under 15 years of age in both communities. A total of 281 urine samples obtained in both communities were processed for the determination of pesticides with high-performance liquid chromatography together with tandem mass spectrometry. In 100% of the samples, at least two pesticides of the 17 reported in the total samples were detected. The presence of malathion, metoxuron, and glyphosate was remarkable in more than 70% of the cases. Substantial differences were detected regarding the other compounds. It is necessary to carry out long-term studies to determine the damage to health resulting from this constant exposure and to inform the health authorities about the problem in order to implement preventive measures.

BACKGROUND: Dementias are rarely considered to be a main cause of death; therefore there are only few studies on Alzheimer's mortality covering long periods. OBJECTIVE: To describe mortality from Alzheimer's disease in México for the period from 1980 to 2014. METHOD: Cross-sectional study where, with official mortality data in Mexico according to codes 331.0 and G30, respectively, of the 9th and 10th revisions of the International Statistical Classification of Diseases and Related Health Problems, crude and standardized Alzheimer's disease mortality rates were obtained, both nationally and by states. RESULTS: From almost being inexistent, deaths from Alzheimer's disease went to a rate of 65.12 per 1000 females and 43.66 per 1000 males in the 2010-2014 five-year period. Throughout the study period, the age group with highest mortality rates for this cause were those older than 80 years, with 0.29 per 100,000 population in 1980-1984 and 55.02 in 100,000 in the 2010-2014 period. The region with the highest mortality was the northwest, with rates higher than 2.28 per 100,000 population. CONCLUSIONS: Mortality from Alzheimer's disease is a public health problem in Mexico with a growing trend, especially among women and older adults. Early diagnostic measures and opportune treatment are required in primary care in order to reduce this problem.
INTRODUCCIÓN: Raramente se considera a las demencias como causa principal de muerte, por consiguiente existen pocos estudios sobre la mortalidad por Alzheimer a través de largos periodos. OBJETIVO: Describir la mortalidad por enfermedad de Alzheimer en México durante el periodo 1980-2014. MÉTODO: Estudio transversal en el que, con datos oficiales de mortalidad en México según los códigos 331.0 y G30 de la novena y décima revisiones de la Clasificación Estadística Internacional de Enfermedades y Problemas Relacionados con la Salud, se obtuvieron tasas crudas y estandarizadas de mortalidad por enfermedad de Alzheimer, nacional y por entidad federativa. RESULTADOS: De ser casi inexistentes, en el quinquenio 2010-2014 se registraron tasas de 65.12 y 43.66 muertes por enfermedad de Alzheimer por cada 1000 mujeres y 1000 hombres, respectivamente. En todo el periodo estudiado, el grupo etario con las mayores tasas de mortalidad por esta causa fue el de mayores de 80 años, con 0.29 en 100 000 habitantes durante 1980-1984 y 55.02 durante 2010-2014. La región con mayor mortalidad fue la noroeste, con tasas mayores a 2.28 en 100 000 habitantes. CONCLUSIONES: La mortalidad por enfermedad de Alzheimer es un problema de salud pública en México con tendencia creciente, especialmente entre mujeres y adultos mayores. Se requieren medidas diagnósticas precoces y tratamiento oportuno en primer nivel para aminorar este problema.

Resumen Se realizó una revisión narrativa con análisis temático sobre las aportaciones de los paradigmas científicos al conocimiento de la prescripción inadecuada de medicamentos. Se buscaron artículos de acceso abierto indexados en PubMed© entre 2010-2014, y se sistematizó información sobre el paradigma, tipo de publicación, perspectiva teórica, objetivo, método y resultados. De los 992 artículos encontrados, se seleccionaron 118, y se tomó una muestra propositiva de 15, según su diseño, representando los cuatro paradigmas. Los artículos positivistas reportaron prevalencia, factores asociados, efectividad de intervenciones y criterios de evaluación; los interpretativos explicaron las causas del problema según los involucrados; los críticos denunciaron la influencia de la industria farmacéutica; y el participativo abordó el problema secundariamente y lo solucionó en un escenario para una enfermedad y grupo farmacológico específicos. Se concluyó que la prescripción inadecuada de medicamentos como problema de investigación en salud pública recibe aportes de los cuatro paradigmas, con dominio del positivismo, lo que se atribuye al carácter paradigmático de la ciencia desde la que se le aborda habitualmente, y que una perspectiva multi-paradigmática es el mejor abordaje.
Abstract This study conducted a narrative review with thematic analysis about contributions of scientific paradigms to knowledge of inadequate drugs prescription. We searched open access articles indexed in PubMed© between 2010 and 2014, and we systematized information about scientific paradigm, publication type, theoretical perspective, objective, method and results. From the 992 articles found, 118 were selected. From those, we chose a purposive sample of 15, according to the design of the studies, representing the four paradigms. The positivists articles reported prevalence, associated factors, effectiveness of interventions and evaluation criteria; the interpretive explained the causes of the problem according to those involved; the critics denounced the influence of pharmaceutical industry; and the participative addressed the problem secondarily and solved it in a scenario for a specific disease and pharmacological. We concluded that the inadequate drugs prescription as research problem in public health had contributions from the four paradigms, with dominance of positivism, which is attributed to the paradigmatic perspective of the science, from which it is usually studied, and that a multi-paradigmatic perspective is the best approach to the public health issue.

The occurrence of Chronic Kidney Disease (CKD) of unknown etiology in autochthonous child populations residing along the Lake Chapala lakeshore is endemic (Jalisco, México). The objective of this study was to determine the prevalence of albuminuria in the pediatric population and to measure the glomerular filtration rate in children with two positive albuminuria tests. Urinary albumin was measured in 394 children. Subjects with two or more positive albuminuria test donated blood samples for the determination of serum biomarkers. From a rural community with 565 children under the age of 17 years, 394 (69.7%) participated with first morning urine samples. A total of 180 children were positive (with two or more positive albuminuria tests). The prevalence of albuminuria among the children participating in the study was 45.7%. Of the 180 children with persistent albuminuria, 160 (88.9%) were tested for serum creatinine, urea, and cystatin C. The 68.1% of the children studied, were found in stages 3a and 3b of the Kidney Disease Improving Global Outcomes (KDIGO) classification (mean glomerular filtration rate (GFR) 51.9 and 38.4 mL/min/1.73 m² respectively). The lowest frequencies were for classifications 1 and 4. None of the subjects was classified as grade 5. The prevalence of albuminuria in children from this rural community is 3-5 times higher than reported in international literature. Regarding GFR, more than 50% of children studied are under 60 mL/min/1.73 m². It is a priority to find the causes of albuminuria and CKD in this Mexican region.

The presence of albumin in urine has been used for more than four decades as a marker of renal and cardiovascular damage. Most of the information on this marker is related to adults. The prevalence of albuminuria in the pediatric population has been reported as being 2.2-12.8% in some countries. Most research in this field is related to albuminuria and diseases, such as diabetes and hypertension. Using the methodology described by Arksey and O'Malley in 2005, a scoping review was carried out to show that the presence of albumin in urine in the pediatric population might be associated with environmental, demographic, congenital, infectious, and non-infectious factors. The information collected is supported by 74 references present in PubMed. The results reveal the multiple causes associated with albuminuria in the pediatric population. This information can be very useful for clinical practice by adding knowledge about albuminuria behavior in children.

Resumen: Introducción: El catéter venoso central (CVC) es necesario para la monitorización y tratamiento de pacientes en estado crítico; sin embargo, su uso incrementa el riesgo de bacteriemia. El objetivo del estudio fue cuantificar la incidencia de bacteriemia relacionada con catéter venoso central (BRCVC) e identificar los factores asociados con esta infección. Métodos: Se realizó un estudio de cohorte prospectivo en un hospital de concentración del occidente de México. Para conocer la asociación entre BRCVC y las variables en estudio, se realizó un análisis multivariado con regresión de Cox. Resultados: Se estudiaron 204 pacientes con CVC. La edad promedio fue de 4.6 años; el 66.2% fue del sexo masculino. Los sitios de inserción del catéter fueron la vena subclavia (72.5%, n = 148), la vena yugular (20.1%, n = 41) o la vena femoral (7.4%, n = 15). La incidencia de BRCVC fue de 6.5 eventos por 1,000 días catéter. Los microorganismos identificados fueron cocos Gram positivos (37.5%, n = 6), bacilos Gram negativos (37.5%, n = 6) y Candida albicans (25%, n = 4). Se observó que la mayor manipulación del catéter por día se asoció con bacteriemia (HR 1.14, IC95% 1.06-1.23), mientras que el uso de antibióticos intravenosos mostró un efecto protector (HR 0.84, IC95% 0.76-0.92). Conclusiones: Además de las medidas máximas de precaución al momento de colocar o manipular el catéter, es conveniente disminuir lo más posible las desconexiones entre el equipo de venoclisis y el CVC. Los antibióticos mostraron un efecto protector; sin embargo, se debe considerar el riesgo de favorecer resistencias antimicrobianas.
Abstract: Background: Central venous catheters (CVC) are needed for monitoring and treatment of critically ill patients; however, their use increases the risk of bacteremia. The aim of the study was to quantify the incidence of central venous catheter-related bacteremia (CVCRB) and to identify factors associated with this infection. Methods: A prospective cohort study was conducted in a concentration hospital of western Mexico. The association of CVCRB and study variables was investigated using multivariate Cox regression analysis. Results: Two hundred four patients with CVC were studied. The average age was 4.6 years; 66.2% were male. Insertion sites of the catheters were subclavian vein 72.5% (n = 148), jugular vein 20.1% (n = 41) and femoral vein 7.4% (n = 15). CVCRB incidence was 6.5 events/1,000 catheter days; microorganisms identified were gram-positive cocci 37.5% (n = 6), gram-negative bacilli 37.5% (n = 6) and Candida albicans 25% (n = 4). It was observed that the increase in catheter manipulations per day was associated with bacteremia (HR 1.14, 95% CI 1.06 - 1.23), whereas the use of intravenous antibiotics showed a protective effect (HR 0.84, 95% CI 0.76-0.92). Conclusions: In addition to strategies of maximum caution when placing or manipulating the catheter, we recommend decreasing, as much as possible, disconnects between the CVC and infusion line. Antibiotics showed a protective effect, but the outcome is uncertain and promotion of antimicrobial resistance should be considered.

RESUMEN
BACKGROUND: To associated mental health factors with tobacco-smoking in the last month in scholastic adolescents. METHODS: An analytic transversal study with 1134 students in the first year of senior studies in a government preparatory school. Ten mental health factors were evaluated: self-esteem, impulsiveness, depressive symptoms, suicide ideation, disordered eating, recreation, locus of control, relationship with father, relationship with mother and stress. RESULTS: We found mental health factors differences between men and women. In the risk analysis, the factors which associated with tobacco smoking in men were high self-esteem, impulsiveness, age and tobacco-smoking in friends. For the women suicide ideation, impulsiveness disordered eating, age and tobacco-smoking in friends and brothers. After the logistic regression were associated impulsiveness and tobacco-smoking in friends for both, high self-esteem and age for men, and tobacco-smoking in brothers for women. CONCLUSIONS: Mental health factors are different for men and women. However, all of them are a reference that tobacco-smoking is associated with the inner world of teens that are meaning differently for men and women.

ResumenIntroducción: Las quemaduras son un problema de salud pública ubicado dentro de las 20 principales causas de morbilidad en México. Uno de los grupos más vulnerables son los niños. Al realizar un análisis de los casos, se aporta para un mejor entendimiento del problema y pueden generarse medidas preventivas al respecto. El objetivo de este trabajo fue determinar el perfil epidemiológico de niños con quemaduras que ingresan a la Unidad de Niños con Quemaduras del Hospital Civil de Guadalajara Dr. Juan I. Menchaca.Métodos: Se realizó un estudio transversal que incluyó características demográficas del lesionado, de sus padres y de las quemaduras de niños atendidos durante 2009 a 2011. El análisis estadístico se llevó a cabo mediante el cálculo de frecuencias absolutas, proporciones e intervalos de confianza de 95%.Resultados: El perfil epidemiológico de los niños lesionados fue principalmente de varones (63.4%) menores de cinco años de edad (65.2%), con escolaridad de acuerdo con su edad (69.2%); hijos de padres menores de 35 años con escolaridad básica. Las lesiones fueron causadas por agua (56.2%) durante el lapso de las 12 p.m. a las 11:59 p.m. (73.0%) produciendo quemaduras de segundo grado superficial y profundo o menores (69.2%) que afectaron menos del 20% de la superficie corporal total (74.5%).Conclusiones: Este perfil epidemiológico permite ampliar el panorama de las acciones preventivas, iniciando con investigaciones científicas que orienten el rumbo que se debe seguir, trabajando conjuntamente con instituciones públicas y privadas en la elaboración de programas y estrategias, así como el establecimiento de una política pública para lesiones no intencionales.
AbstractBackground: Burns are a public health problem, ranking among the 20 principal causes of morbidity in Mexico. Children are a more vulnerable group to suffer from these injuries. For that reason, we analyzed cases in order to gain a better comprehension and to propose preventive measures for this problem. The aim of the study was to determine the epidemiological profile of those injuries to allow us to plan and implement actions for burn prevention.Methods: We conducted a cross-sectional study that included demographic characteristics of the child, the parents and the burn injuries from children treated at this Burn Unit. Statistical analysis was done to calculate amounts, proportions and 95% confidence intervals.Results: The epidemiological profile of the injuries included males (63.4%) <5 years of age (65.2%) with educational level according to their age (56.2%). Parents of the included children were <35 years old with basic educational level. Burns were caused by hot water (56.2%) and occurred between noon and midnight (73.0%). The majority of the burns were shallow and deep second-degree or minor (69.2%) and affected <20% of body surface area (74.5%).Conclusions: This epidemiological profile paved the way for preventive actions beginning with scientific research to guide the actions in a progressive direction along with the cooperative actions of public and private institutions in the development of programs and strategies. The end result would be the establishment of a public policy for accidental injuries.

RESUMEN
Mitochondrial dysfunction has been thought to contribute to Alzheimer disease (AD) pathogenesis through the accumulation of mitochondrial DNA mutations and net production of reactive oxygen species (ROS). Mitochondrial cytochrome c-oxidase plays a key role in the regulation of aerobic production of energy and is composed of 13 subunits. The 3 largest subunits (I, II, and III) forming the catalytic core are encoded by mitochondrial DNA. The aim of this work was to look for mutations in mitochondrial cytochrome c-oxidase gene II (MTCO II) in blood samples from probable AD Mexican patients. MTCO II gene was sequenced in 33 patients with diagnosis of probable AD. Four patients (12%) harbored the A8027G polymorphism and three of them were early onset (EO) AD cases with familial history of the disease. In addition, other four patients with EOAD had only one of the following point mutations: A8003C, T8082C, C8201T, or G7603A. Neither of the point mutations found in this work has been described previously for AD patients, and the A8027G polymorphism has been described previously; however, it hasn't been related to AD. We will need further investigation to demonstrate the role of the point mutations of mitochondrial DNA in the pathogenesis of AD.
RESUMEN
OBJECTIVE: To determine the prevalence of sexual function alterations in Mexican subjects with diabetes mellitus (DM) attended in a highly specialized medical unit. MATERIAL AND METHODS: Sociodemographic variables were evaluated, and the DM, male and female sexual function with an ad hoc questionnaire and Female Sexual Function Index or International Index of Erectile Function. Data were processed using the SPSS statistical analysis program version 19. RESULTS: 212 subjects were selected, 120 women and 92 men. The global prevalence of sexual function alterations was 81.1%. In women it was 83.3% and 78.3% in men, with 73.7% and 63.1%, respectively, in those under 40 years of age. The highest prevalence occurred among women aged 50-59 years and men between 60-69 (± 95%), married (> 80%), pensioners and women of the household (± 90%), with primary educational level (100%), men with type 1 DM or women with type 2 DM (> 85%), and with 21 years or more of DM diagnosis (90-100%). CONCLUSION: The prevalence of sexual function alterations in Mexican subjects with DM is higher than worldwide reported; women have higher prevalence of sexual function alterations than men.
RESUMEN
Introduction During the last decade we have observed important climate changes, especially in environmental temperatures. There is considerable information linking the increase in hot weather and human health. For example, hot weather is associated with an increased risk of suicide in different countries around the world. Objective To evaluate the relationship between suicide rates and the environmental temperature in Baja California Sur, Mexico, from 1985 to 2008. Method Suicide mortality data for Baja California Sur (BCS) were obtained for the years 1985-2008 from the Instituto Nacional de Estadística, Geografía e Informática (INEGI). The selected codes were: E950-E959 (ICD-9) and X60-X84, Y87.0 (ICD-10) for BCS. The BCS weather data used was the maximum temperature from 1985 to 2008, obtained from the Extractor Rápido de Información Climatológica (ERIC III). Lineal and quadratic models were used to assess the annual rate changes of suicide and generalized lineal models (GLM) to assess the effect of the climatological variables to the suicide rate. The p≤0.05 was considered significant. Results In BCS, 582 suicide deaths were reported from 1985 to 2008. The 9% (53) of the total reported were women with a yearly average rate 1.6/100 000; 91% (529) were men with a yearly average rate 16.3/100 000. Lineal and quadratic models explained the tendency of the annual increment observed in the number of suicides in both seasons. The quadratic model better explained such increment during the warmer months (R²=0.64 p<0.01). The temperature was positively correlated with the rate of suicides in both seasons (p<0.01). Two predictive GLMs were created by season. Discussion These results suggest a potential link between an increase in environmental temperature and the rates of suicide during 24 years in BCS. This relationship is clear during the hot season; however, a positive trend was found during the cold season, perhaps due to the result of warmer winters.
Introducción Durante las últimas décadas se ha podido apreciar un cambio en las variables climáticas, en especial en la temperatura ambiental. Hay evidencias que asocian el aumento de la temperatura ambiental con el incremento en las tasas de mortalidad por suicidio. Objetivo Evaluar la relación entre la tasa de suicidio y la temperatura ambiental en Baja California Sur (BCS) durante los años 1985-2008. Método Los datos de suicidio fueron obtenidos de las bases de Mortalidad del INEGI de 1985-2008. Se tabularon los registros con códigos: E950-E959 CIE-9 y X60-X84, Y87.0 CIE-10 para BCS. En el análisis climático se usaron las temperaturas máximas de 1985 al 2008 para BCS del Extractor Rápido de Información Climatológica (ERIC III). Para evaluar la tendencia, se utilizaron modelos de regresión lineal y cuadráticos. Los modelos lineales generalizados (GLM) se utilizaron para evaluar el efecto de las variables ambientales sobre la tasa de suicidios, con una significancia de p≤0.05. Resultados Un total de 582 suicidios ocurrieron en BCS de 1985 a 2008. Las mujeres representaron el 9% (53), con tasa anual promedio de 1.6/100 000. Los hombres 91% (529), con tasa promedio anual de 16.3/100 000. La tendencia de incremento anual se explicó con modelos lineales simples y cuadráticos en ambas temporadas. En los meses cálidos el modelo cuadrático explicó mejor dicho incremento (R²=0.64 p<0.01). La temperatura se correlacionó positivamente con la tasa en ambas temporadas (p<0.01). Se generaron dos modelos GLM predictivos por temporada. Discusión En este trabajo se observó una posible relación entre el incremento de la temperatura ambiental y el número de suicidios registrados durante 24 años en BCS. Esta relación se encuentra bien definida en los meses cálidos, pero con una tendencia en aumento para los meses fríos.
RESUMEN
OBJECTIVE: To determine THg levels in milk of women from Northwest Mexico and its potential association with maternal factors such as diet and tobacco smoke. METHOD: The study was performed in 108 milk samples donated by women in Baja California Sur. Data were stratified into three groups of 36 donors by number of pregnancies. General data, smoking, exposure to environmental tobacco smoke and seafood intake were explored. THg levels were measured using atomic absorption spectrophotometry. The difference between groups was evaluated with non-parametric statistics. To explain the possible association of the different variables with THg concentrations in milk, generalized linear models were performed. RESULTS: THg levels ranged from 1.23 µg/L in single-pregnancy women (GI) to 2.96 µg/L for women with 3 or more pregnancies (GIII) (p = 0.07). In the GI group THg concentration was 175% higher (p = 0.02) in women who do not eat fish, compared to those who eat fish. In the generalized linear model to adjust THg concentrations, the variables were: age, number of pregnancies, breastfeeding duration and exposure to tobacco smoke (p ≤ 0.05). CONCLUSIONS: Fish consumption was the factor that better adjusted models, relative to THg levels. The contribution associated to this factor was low; therefore, consumption of fish from the coast of Baja California Sur is safe. Tobacco increased Hg concentrations in breast milk; it is necessary to avoid the smoking habit during pregnancy and breast-feeding.
Objetivo: Determinar los niveles de mercurio total (THg) en leche de mujeres del Noroeste de México y su posible asociación con factores maternos, la dieta y el tabaco. Método: El estudio se realizó en leches donadas por 108 mujeres de Baja California Sur. Se estratificaron en tres grupos de 36 donantes según el número de gesta. Se exploraron datos generales, hábito tabáquico, exposición al humo de tabaco ambiental, ingesta de mariscos y pescados. Los niveles de THg fueron cuantificados utilizando espectrofotometría de absorción atómica. La diferencia entres grupos se evaluó con estadística no paramétrica. Para explicar la posible asociación de las diferentes variables estudiadas y las concentraciones de THg en la leche, se realizaron modelos lineales generalizados. Resultados: Los niveles de THg fueron desde 1.23 ?g/L en las primigestas (GI) a 2,96 ?g/L para las mujeres con 3 o más gestas (GIII) (p = 0,07). En el grupo de GI encontramos una concentración del THg 175% mayor (p = 0,02) entre las mujeres que no comen pescado, en comparación con las que si comen pescado. En el modelo lineal generalizado ajustado por las concentraciones de THg, las variables fueron: edad, número de embarazos, duración de la lactancia y exposición al tabaco (p =?0,05). Conclusiones: El consumo de pescado fue el factor que mejor ajustó los modelos en relación a los niveles de THg. El aporte de Hg por la dieta que se pudo asociar fue bajo, por lo que el consumo de pescado de las costas de Baja California Sur es seguro. El tabaco, incrementa las concentraciones de Hg en la leche materna, por lo que debe de limitarse su hábito durante el embarazo y la lactancia.

AIM: To analyze the mortality trend by accidental falls in Mexico, from 1979 to 2010. MATERIAL AND METHODS: We used official mortality data in México. Variables included were mortality cause, place of lesion, age, sex, year of mortality registration, size of the town of occurrence, state, occupation, workplace falls. RESULTS: During that period, 124,509 deaths by accidental and intentional falls were registered; of these 77.03% were men. From 1989 (3.20 per 100,000) to 2010 (1.99 per 100,000), the mortality trend was falling (ß = -0.053/ 100,000, p ≤ 0.001). In the majority of states, we found a decreased between 1993-1997 and 2006 to 2010, except in Aguascalientes, Puebla, Baja California Sur, Durango and Nuevo León. CONCLUSIONS: This is the first study in México that showed the descending trend of mortality in accidental falls in the last two decades.

OBJECTIVE: To identify frequency and severity of injuries by type of external cause in people attending emergency services for medical attention. MATERIAL AND METHODS: Cross-sectional study held in the cities of Guadalajara, Colima and Mexico City, from September 2007 to February 2008. All people requiring emergency medical attention due to injuries were included. VARIABLES: sex, age, anatomical area of the injury, type of injury, external cause, type of aggressor and severity according to the abbreviated injury scale. Statistical analysis was univariate simple and multivariate. RESULTS: 26.3% of the emergency medical attention was due to injuries, with the main cause being falls (49.3%). Individuals from 15 to 44 years (55.8%) reported a higher frequency, while those over 60 years presented the most serious injuries. Associated variables to severity were interpersonal aggression (OR 6.7, IC 95% 4.20-10.69) and road traffic injuries (OR 3.00, IC 95% 1.72-5.23). Conclusions. Accidental and intentional injuries represent an important demand of emergency medical attention; with interpersonal aggression and road traffic injuries being responsible for the highest number of serious injuries.
