RESUMEN
INTRODUCTION: Medical students report higher levels of anxiety than students from other majors. Knowledge about their psychological well-being is scarce. OBJECTIVE: To identify sociodemographic and academic factors that predict the level of anxiety and psychological well-being in Mexican medical students. METHOD: Cross-sectional study of Mexican medical students of first (n = 59), third (n = 43) and fifth semester (n = 59), who answered a sociodemographic questionnaire, Beck Anxiety Inventory, the Psychological Well-being Scale for adults and the Family Adaptability and Cohesion Evaluation Scale. RESULTS: Females showed higher levels of anxiety (p < 0.01). Anxiety in males was similar in the different semesters (p > 0.05); women of third and fifth semesters were more anxious than those at first semester (p < 0.01). Anxiety and psychological well-being were negatively correlated (p < 0.001). The "Less anxiety, higher level of well-being" and "More anxiety, lower level of well-being" subgroups were characterized, and a logistic regression identified that being a woman (OR = 4.70) and not practicing any religion (OR = 2.49) are predictive factors of higher levels of anxiety. CONCLUSIONS: Female medical students constitute a population at risk for higher levels of anxiety and less psychological well-being, which compromises their learning, quality of life and future professional practice.
INTRODUCCIÓN: Estudiantes de medicina reportan mayor ansiedad que estudiantes de otras carreras. El conocimiento sobre su bienestar psicológico es escaso. OBJETIVO: Identificar factores sociodemográficos y académicos predictores del nivel de ansiedad y bienestar psicológico en estudiantes mexicanos de medicina. MÉTODO: Estudio transversal de estudiantes mexicanos de medicina de primer (n = 59), tercer (n = 43) y quinto semestre (n = 59), que contestaron un cuestionario sociodemográfico, la Escala de Ansiedad de Beck, la Escala de Bienestar Psicológico para Adultos y la Escala de Evaluación de la Cohesión y la Adaptabilidad Familiar. RESULTADOS: Las mujeres presentaron mayor ansiedad (p < 0.01). La ansiedad en hombres fue similar en los distintos semestres (p > 0.05); las mujeres de tercer y quinto semestre fueron más ansiosas que las del primero (p < 0.01). Ansiedad y bienestar psicológico correlacionaron negativamente (p < 0.001). Se identificaron los subgrupos "Menor ansiedad, mayor bienestar" y "Mayor ansiedad, menor bienestar", y una regresión logística identificó que ser mujer (OR = 4.70) y no profesar alguna religión (OR = 2.49) son factores predictores de mayor ansiedad. CONCLUSIONES: Las estudiantes de medicina constituyen una población de riesgo para mayor ansiedad y menor bienestar psicológico, lo que compromete su aprendizaje, calidad de vida y futuro ejercicio profesional.

The interest on cannabinoids became evident between the 1940 and 1950 decades. Although the active substance of the plant was not known, a series of compounds with cannabinomimetic activity were synthesized, which were investigated in animals and clinically. The most widely tested was Δ6a, 10a-THC hexyl. Δ6a, 10a-THC dimethylheptyl (DMHP) antiepileptic effects were studied in several children, with positive results being obtained in some cases. DMHP differs from sinhexyl in that its side chain is DMHP instead of n-hexyl. The first cannabinoid isolated from Cannabis sativa was cannabinol, although its structure was correctly characterized several years later. Cannabidiol was isolated some years later and was subsequently characterized by Mechoulam and Shvo. In 2013, the National Academy of Medicine and the Faculty of Medicine of the National Autonomous University of Mexico, through the Seminar of Studies on Entirety, decided to carry out a systematic review on a subject that is both complex and controversial: the relationship between marijuana and health. In recent years, studies have been conducted with cannabis in several diseases: controlled clinical trials on spasticity in multiple sclerosis and spinal cord injury, chronic, essentially neuropathic, pain, movement disorders (Gilles de Latourette, dystonia, levodopa dyskinesia), asthma and glaucoma, as well as non-controlled clinical trials on Alzheimer's disease, neuroprotection, intractable hiccups, epilepsy, alcohol and opioid dependence and inflammatory processes.
El interés por los cannabinoides se hizo evidente entre las décadas de 1940 y 1950. Aunque no se conocía el principio activo de la planta, se sintetizaron compuestos con actividad cannabinomimética, los cuales fueron investigados en animales y en la clínica. El más probado fue el ∆6a,10a-THC hexilo. Las acciones antiepilépticas del ∆6a,10a-THC dimetilheptil fueron estudiadas en varios niños; en algunos casos se obtuvieron resultados positivos. El ∆6a,10a-THC dimetilheptil se diferencia del sinhexil en que su cadena lateral es dimetilheptilo en vez de n-hexilo. El primer cannabinoide aislado de Cannabis sativa fue el cannabinol, si bien su estructura fue correctamente caracterizada varios años después. El cannabidiol fue aislado algunos años más tarde y caracterizado posteriormente por Mechoulam y Shvo. Durante 2013, la Academia Nacional de Medicina y la Facultad de Medicina de la Universidad Nacional Autónoma de México, a través del Seminario de Estudios sobre la Globalidad, decidieron realizar una revisión sistemática sobre un tema tan complejo como controvertido: la relación entre la marihuana y la salud. En los últimos años se han realizado estudios con cannabis en varias enfermedades: ensayos clínicos controlados sobre espasticidad en esclerosis múltiple y sobre lesiones medulares, dolor crónico fundamentalmente neuropático y trastornos del movimiento (Gilles de Latourette, distonía, discinesia por levodopa), asma y glaucoma, así como ensayos clínicos no controlados sobre Alzheimer, neuroprotección, hipo intratable, epilepsia, dependencia al alcohol y opioides y procesos inflamatorios.

In recent years, the use of stem cells for therapeutic purposes has received attention from research groups. In Mexico, the Mexican Official Standard 260-SSAI-2015 regarding the use of stem and progenitor cells for therapeutic and research purposes is in the process of authorization. Even when this has not been approved, an increasing number of establishments are offering medical services involving the use of stem cells for therapeutic purposes without official regulatory authorization. The Mexican Academy of Medicine of Mexico makes its position public in favor of regulating the use of stem cells and embryos for therapeutic and research purposes.
En años recientes, el uso de células troncales con fines terapéuticos ha recibido atención por grupos de investigación. En México está en proceso de autorización la Norma oficial mexicana 260-SSAI-2015, para la disposición de células troncales y progenitoras con fines terapéuticos y de investigación. Aun cuando esta no ha sido aprobada, cada vez más establecimientos ofrecen servicios médicos con la finalidad de usar células madres con fines terapéuticos sin contar con las autorizaciones sanitarias oficiales. La Academia Nacional de Medicina de México da a conocer su posición acerca de la regulación sobre el uso de células troncales y embriones para fines terapéuticos o de investigación.

BACKGROUND AND OBJECTIVE: About 9% of gastric carcinomas have Epstein-Barr virus (EBV) in the tumour cells, but it is unclear whether viral presence influences clinical progression. We therefore examined a large multicentre case series for the association of tumour EBV status with survival after gastric cancer diagnosis, accounting for surgical stage and other prognostic factors. METHODS: We combined individual-level data on 4599 gastric cancer patients diagnosed between 1976 and 2010 from 13 studies in Asia (n=8), Europe (n=3), and Latin America (n=2). EBV positivity of tumours was assessed by in situ hybridisation. Mortality HRs for EBV positivity were estimated by Cox regression models stratified by study, adjusted for distributions of sex (71% male), age (mean 58 years), stage (52% tumour-node-metastasis stages III or IV), tumour histology (49% poorly differentiated, 57% Lauren intestinal-type), anatomic subsite (70% non-cardia) and year of diagnosis. Variations by study and continent were assessed using study-specific HRs for EBV positivity. RESULTS: During median 3.0 years follow-up, 49% of patients died. Stage was strongly predictive of mortality, with unadjusted HRs (vs stage I) of 3.1 for stage II, 8.1 for stage III and 13.2 for stage IV. Tumour EBV positivity was 8.2% overall and inversely associated with stage (adjusted OR: 0.79 per unit change). Adjusted for stage and other confounders, EBV positivity was associated with lower mortality (HR, 0.72; 95% CI 0.61 to 0.86), with low heterogeneity among the study populations (p=0.2). The association did not significantly vary across patient or tumour characteristics. There was no significant variation among the three continent-specific HRs (p=0.4). CONCLUSIONS: Our findings suggest that tumour EBV positivity is an additional prognostic indicator in gastric cancer. Further studies are warranted to identify the mechanisms underlying this protective association.

Helicobacter pylori is the primary cause of gastric cancer. However, monoclonal Epstein-Barr virus (EBV) nucleic acid is also present in up to 10% of these tumors worldwide. EBV prevalence is increased with male sex, nonantral localization and surgically disrupted anatomy. To further examine associations between EBV and gastric cancer, we organized an international consortium of 11 studies with tumor EBV status assessed by in situ hybridization. We pooled individual-level data on 2,648 gastric cancer patients, including 184 (7%) with EBV-positive cancers; all studies had information on cigarette use (64% smokers) and nine had data on alcohol (57% drinkers). We compared patients with EBV-positive and EBV-negative tumors to evaluate smoking and alcohol interactions with EBV status. To account for within-population clustering, multilevel logistic regression models were used to estimate interaction odds ratios (OR) adjusted for distributions of sex (72% male), age (mean 59 years), tumor histology (56% Lauren intestinal-type), anatomic subsite (61% noncardia) and year of diagnosis (1983-2012). In unadjusted analyses, the OR of EBV positivity with smoking was 2.2 [95% confidence interval (CI) 1.6-3.2]. The OR was attenuated to 1.5 (95% CI 1.01-2.3) by adjustment for the possible confounders. There was no significant interaction of EBV status with alcohol drinking (crude OR 1.4; adjusted OR 1.0). Our data indicate the smoking association with gastric cancer is stronger for EBV-positive than EBV-negative tumors. Conversely, the null association with alcohol does not vary by EBV status. Distinct epidemiologic characteristics of EBV-positive cancer further implicate the virus as a cofactor in gastric carcinogenesis.

Background: Central and bridge nodes can drive significant overall improvements within their respective networks. We aimed to identify them in 16 prevalent chronic diseases during the coronavirus disease 2019 (COVID-19) pandemic to guide effective intervention strategies and appropriate resource allocation for most significant holistic lifestyle and health improvements. Methods: We surveyed 16 512 adults from July 2020 to August 2021 in 30 territories. Participants self-reported their medical histories and the perceived impact of COVID-19 on 18 lifestyle factors and 13 health outcomes. For each disease subgroup, we generated lifestyle, health outcome, and bridge networks. Variables with the highest centrality indices in each were identified central or bridge. We validated these networks using nonparametric and case-dropping subset bootstrapping and confirmed central and bridge variables' significantly higher indices through a centrality difference test. Findings: Among the 48 networks, 44 were validated (all correlation-stability coefficients >0.25). Six central lifestyle factors were identified: less consumption of snacks (for the chronic disease: anxiety), less sugary drinks (cancer, gastric ulcer, hypertension, insomnia, and pre-diabetes), less smoking tobacco (chronic obstructive pulmonary disease), frequency of exercise (depression and fatty liver disease), duration of exercise (irritable bowel syndrome), and overall amount of exercise (autoimmune disease, diabetes, eczema, heart attack, and high cholesterol). Two central health outcomes emerged: less emotional distress (chronic obstructive pulmonary disease, eczema, fatty liver disease, gastric ulcer, heart attack, high cholesterol, hypertension, insomnia, and pre-diabetes) and quality of life (anxiety, autoimmune disease, cancer, depression, diabetes, and irritable bowel syndrome). Four bridge lifestyles were identified: consumption of fruits and vegetables (diabetes, high cholesterol, hypertension, and insomnia), less duration of sitting (eczema, fatty liver disease, and heart attack), frequency of exercise (autoimmune disease, depression, and heart attack), and overall amount of exercise (anxiety, gastric ulcer, and insomnia). The centrality difference test showed the central and bridge variables had significantly higher centrality indices than others in their networks (P < 0.05). Conclusion: To effectively manage chronic diseases during the COVID-19 pandemic, enhanced interventions and optimised resource allocation toward central lifestyle factors, health outcomes, and bridge lifestyles are paramount. The key variables shared across chronic diseases emphasise the importance of coordinated intervention strategies.

Background: In this study, we assessed the general population's fears towards various diseases and events, aiming to inform public health strategies that balance health-seeking behaviours. Methods: We surveyed adults from 30 countries across all World Health Organization (WHO) regions between July 2020 and August 2021. Participants rated their fear of 11 factors on an 11-point Likert scale. We stratified the data by age and gender and examined variations across countries and regions through multidimensional preference analysis. Results: Of the 16 512 adult participants, 62.7% (n = 10 351) were women. The most feared factor was the loss of family members, reported by 4232 participants (25.9%), followed by cancer (n = 2248, 13.7%) and stroke (n = 1416, 8.7%). The highest weighted fear scores were for loss of family members (mean (xÌ) = 7.46, standard deviation (SD) = 3.04), cancer (xÌ = 7.00, SD = 3.09), and stroke (xÌ = 6.61, SD = 3.24). The least feared factors included animals/insects (xÌ = 3.72, SD = 2.96), loss of a mobile phone (xÌ = 4.27, SD = 2.98), and social isolation (xÌ = 4.83, SD = 3.13). Coronavirus disease 2019 (COVID-19) was the sixth most feared factor (xÌ = 6.23, SD = 2.92). Multidimensional preference analyses showed distinct fears of COVID-19 and job loss in Australia and Burundi. The other countries primarily feared loss of family members, cancer, stroke, and heart attacks; this ranking was consistent across WHO regions, economic levels, and COVID-19 severity levels. Conclusions: Fear of family loss can improve public health messaging, highlighting the need for bereavement support and the prevention of early death-causing diseases. Addressing cancer fears is crucial to encouraging the use of preventive services. Fear of non-communicable diseases remains high during health emergencies. Top fears require more resources and countries with similar concerns should collaborate internationally for effective fear management.

BACKGROUND: Latin America has among the highest gastric cancer incidence rates in the world, for reasons that are still unknown. In order to identify region-specific risk factors for gastric cancer, we conducted a meta-analysis summarizing published literature. METHODS: Searches of PubMed and regional databases for relevant studies published up to December 2011 yielded a total of 29 independent case-control studies. We calculated summary odds ratios (OR) for risk factors reported in at least five studies, including socioeconomic status (education), lifestyle habits (smoking and alcohol use), dietary factors (consumption of fruits, total vegetables, green vegetables, chili pepper, total meat, processed meat, red meat, fish, and salt), and host genetic variants (IL1B-511T, IL1B-31C, IL1RN*2, TNFA-308A, TP53 codon 72 Arg, and GSTM1 null). Study-specific ORs were extracted and summarized using random-effects models. RESULTS: Chili pepper was the only region-specific factor reported in at least five studies. Consistent with multifactorial pathogenesis, smoking, alcohol use, high consumption of red meat or processed meat, excessive salt intake, and carriage of IL1RN*2 were each associated with a moderate increase in gastric cancer risk. Conversely, higher levels of education, fruit consumption, and total vegetable consumption were each associated with a moderately decreased risk. The other exposures were not significantly associated. No prospective study data were identified. CONCLUSION: Risk factor associations for gastric cancer in Latin America are based on case-control comparisons that have uncertain reliability, particularly with regard to diet; the specific factors identified and their magnitudes of association are largely similar to those globally recognized. Future studies should emphasize prospective data collection and focus on region-specific exposures that may explain high gastric cancer risk.

BACKGROUND: The expression of empathy improves the quality of health care, which is why its instruction is suggested during the years of academic training of medical students. However, expressing empathy can also cause anxiety and impair psychological well-being. OBJECTIVE: To identify profiles that describe the relationship between empathy, anxiety and psychological well-being in Mexican medical students. METHOD: Cross-sectional study in Mexican medical students completed the Multidimensional Empathy Scale, the Beck Anxiety Inventory, and the Psychological Well-Being Scale for Adults. RESULTS: Women presented greater empathy and anxiety and lower psychological well-being (p < 0.01). Anxiety in students of the last year of training was lower compared to students of the first and second year (p < 0.01). Four profiles were detected: 1) men, minimal anxiety, low empathy; 2) first-year students, moderate to severe anxiety, low psychological well-being, high empathy; 3) last year of training, mild anxiety, adequate psychological well-being, medium empathy; 4) women, second and third year of training, very high empathy. CONCLUSIONS: Medical students in their first year of training constitute a population at risk. Attention strategies are necessary for this student group.
ANTECEDENTES: La expresión de empatía mejora la calidad de la atención a la salud, y por ello se sugiere su instrucción durante los años de formación académica de estudiantes de medicina. No obstante, la expresión de empatía también puede ocasionar ansiedad y perjudicar el bienestar psicológico. OBJETIVO: Identificar perfiles que describan la relación entre empatía, ansiedad y bienestar psicológico en estudiantes mexicanos de medicina. MÉTODO: Estudio transversal en estudiantes mexicanos de medicina que completaron la Escala Multidimensional de Empatía, el Inventario de Ansiedad de Beck y la Escala de Bienestar Psicológico para Adultos. RESULTADOS: Las mujeres presentaron mayor empatía y ansiedad, y menor bienestar psicológico (p < 0.01). La ansiedad en estudiantes del último año de formación fue menor que en los estudiantes de primer y segundo año (p < 0.01). Se detectaron cuatro perfiles: 1) hombres, ansiedad mínima, empatía baja; 2) estudiantes de primer año de formación, ansiedad moderada a grave, bienestar psicológico bajo, empatía alta; 3) último año de formación, ansiedad leve, bienestar psicológico adecuado, empatía media; 4) mujeres, segundo y tercer años de formación, muy alta empatía. CONCLUSIONES: Los estudiantes de medicina del primer año de formación constituyen una población de riesgo. Son necesarias estrategias de atención para este grupo estudiantil.

Background: The interconnected nature of lifestyles and interim health outcomes implies the presence of the central lifestyle, central interim health outcome and bridge lifestyle, which are yet to be determined. Modifying these factors holds immense potential for substantial positive changes across all aspects of health and lifestyles. We aimed to identify these factors from a pool of 18 lifestyle factors and 13 interim health outcomes while investigating potential gender and occupation differences. Methods: An international cross-sectional study was conducted in 30 countries across six World Health Organization regions from July 2020 to August 2021, with 16 512 adults self-reporting changes in 18 lifestyle factors and 13 interim health outcomes since the pandemic. Results: Three networks were computed and tested. The central variables decided by the expected influence centrality were consumption of fruits and vegetables (centrality = 0.98) jointly with less sugary drinks (centrality = 0.93) in the lifestyles network; and quality of life (centrality = 1.00) co-dominant (centrality = 1.00) with less emotional distress in the interim health outcomes network. The overall amount of exercise had the highest bridge expected influence centrality in the bridge network (centrality = 0.51). No significant differences were found in the network global strength or the centrality of the aforementioned key variables within each network between males and females or health workers and non-health workers (all P-values >0.05 after Holm-Bonferroni correction). Conclusions: Consumption of fruits and vegetables, sugary drinks, quality of life, emotional distress, and the overall amount of exercise are key intervention components for improving overall lifestyle, overall health and overall health via lifestyle in the general population, respectively. Although modifications are needed for all aspects of lifestyle and interim health outcomes, a larger allocation of resources and more intensive interventions were recommended for these key variables to produce the most cost-effective improvements in lifestyles and health, regardless of gender or occupation.

Background: The health area being greatest impacted by coronavirus disease 2019 (COVID-19) and residents' perspective to better prepare for future pandemic remain unknown. We aimed to assess and make cross-country and cross-region comparisons of the global impacts of COVID-19 and preparation preferences of pandemic. Methods: We recruited adults in 30 countries covering all World Health Organization (WHO) regions from July 2020 to August 2021. 5 Likert-point scales were used to measure their perceived change in 32 aspects due to COVID-19 (-2 = substantially reduced to 2 = substantially increased) and perceived importance of 13 preparations (1 = not important to 5 = extremely important). Samples were stratified by age and gender in the corresponding countries. Multidimensional preference analysis displays disparities between 30 countries, WHO regions, economic development levels, and COVID-19 severity levels. Results: 16 512 adults participated, with 10 351 females. Among 32 aspects of impact, the most affected were having a meal at home (mean (m) = 0.84, standard error (SE) = 0.01), cooking at home (m = 0.78, SE = 0.01), social activities (m = -0.68, SE = 0.01), duration of screen time (m = 0.67, SE = 0.01), and duration of sitting (m = 0.59, SE = 0.01). Alcohol (m = -0.36, SE = 0.01) and tobacco (m = -0.38, SE = 0.01) consumption declined moderately. Among 13 preparations, respondents rated medicine delivery (m = 3.50, SE = 0.01), getting prescribed medicine in a hospital visit / follow-up in a community pharmacy (m = 3.37, SE = 0.01), and online shopping (m = 3.33, SE = 0.02) as the most important. The multidimensional preference analysis showed the European Region, Region of the Americas, Western Pacific Region and countries with a high-income level or medium to high COVID-19 severity were more adversely impacted on sitting and screen time duration and social activities, whereas other regions and countries experienced more cooking and eating at home. Countries with a high-income level or medium to high COVID-19 severity reported higher perceived mental burden and emotional distress. Except for low- and lower-middle-income countries, medicine delivery was always prioritised. Conclusions: Global increasing sitting and screen time and limiting social activities deserve as much attention as mental health. Besides, the pandemic has ushered in a notable enhancement in lifestyle of home cooking and eating, while simultaneously reducing the consumption of tobacco and alcohol. A health care system and technological infrastructure that facilitate medicine delivery, medicine prescription, and online shopping are priorities for coping with future pandemics.

OBJECTIVE: To identify the association between general empathy and medical empathy. Detect predictors of the level of medical empathy from general empathy. To determine the psychosocial profile that describes the relationship between general empathy, medical empathy, and demographic and academic characteristics in medical students. METHOD: Descriptive cross-sectional design. Medical students completed the Interpersonal Reactivity Index (IRI) and the Jefferson Scale of Physician Empathy-student version (JSPE-S). RESULTS: Relatively high levels of general and medical empathy were detected. The total score of the IRI and the JSPE-S and their dimensions correlated positively (r = 0.14-0.52), except for the dimension personal distress of the IRI. The score of the IRI dimension empathic concern was the best predictor of the JSPE-S score and its dimensions (b = 0.27-0.54). Four profiles were detected: 1) men, preference for technology-oriented specialty, less empathy; 2) pre-clinical period students, less empathy; 3) students of the clinical period, greater empathy; and 4) women, preference for patient-oriented specialty, greater empathy. CONCLUSIONS: General and medical empathy are associated. Differentiated empathic profiles will allow the design of instructional strategies in empathy according to the specific needs of each one.
OBJETIVO: Identificar la asociación entre empatía general y empatía médica. Detectar predictores del nivel de empatía médica a partir de la empatía general. Determinar el perfil psicosocial que describa la relación entre empatía general, empatía médica y características demográficas y académicas en estudiantes de medicina. MÉTODO: Estudio transversal descriptivo. Estudiantes de medicina completaron el Índice de Reactividad Interpersonal (IRI) y la Escala de Empatía Médica de Jefferson versión estudiantil (EEMJ-E). RESULTADOS: Se detectaron niveles relativamente altos de empatía general y médica. El puntaje total del IRI y la EEMJ-E y sus dimensiones se correlacionaron positivamente (r = 0.14-0.52), excepto para la dimensión malestar personal del IRI. El puntaje en la dimensión preocupación empática del IRI fue el mejor predictor del puntaje de la EEMJ-E y sus dimensiones (b = 0.27-0.54). Se detectaron cuatro perfiles: 1) hombres, preferencia por especialidad orientada a la tecnología, menor empatía; 2) estudiantes del periodo preclínico, menor empatía; 3) estudiantes del periodo clínico, mayor empatía; y 4) mujeres, preferencia por especialidad orientada al paciente, mayor empatía. CONCLUSIONES: La empatía general y la empatía médica se encuentran asociadas. Unos perfiles empáticos diferenciados permitirán el diseño de estrategias de instrucción en empatía acordes con las necesidades específicas de cada uno.

OBJECTIVE: To describe the relationship between blood lead levels (BLL) and poor school performance. MATERIAL AND METHODS: A cross-sectional study was carried out in 1996 among 792 schoolchildren aged 7-14 years, who attended the outpatient units of five pediatric hospitals of Mexico City. BLL was measured together with lead exposure and academic performance. RESULTS: Reported BLL and geometric means (GM) were 8.6 microg/dL and 7.7 microg/dL, respectively. The main source of exposure was the use of glazed pottery (difference of use =-1.182; p = 0.000). Among schoolchildren who failed any school year, GM of the BLL was 8.1 microg/dL, compared with children who did not fail (GM = 7.6 microg/dL; p = 0.240). The risk of failing a school year between the 1st and 3rd grade with a BLL greater than 10 microg/dL was 1.73 (p = 0.012, IC 95% 1.13-2.66) and from 1st to 4th grade was 1.62 (p = 0.021, IC 95% 1.07-2.46). CONCLUSIONS: Blood lead levels, among other conditions, may contribute to the failure in school performance observed in the children participating in this study.

Objective: Identify profiles that describe the way in which the level of empathy and assertiveness are associated with the level of anxiety and depression, sex and year of academic training in nursing students. Method: 909 nursing students completed the Multidimensional Empathy Scale, the Assertiveness factor of the Multidimensional Assertiveness Scale, the Beck Anxiety Inventory and the Beck Depression Inventory. Results: 4 profiles were obtained: 1. Women, "minor" assertiveness, "mild" or "moderate" depression, "moderate" anxiety; 2. "Higher" assertiveness, "mild" anxiety, "medium" empathy, first year of training; 3. High empathy, severe depression and anxiety, third year of academic training; 4. Men, low empathy, minimal depression and anxiety, fourth year of training. Conclusion: A "functional" profile was detected, with greater assertiveness, a medium level of empathy and mild anxiety. A low level of empathy is associated with minimal levels of anxiety and depression in men. Finally, low levels of assertiveness are associated with moderate levels of anxiety and depression in women.(AU)

Resumen Introducción: El bienestar psicológico favorece el funcionamiento de la vida personal y social. Para su evaluación, es necesario contar con instrumentos válidos y confiables que permitan decidir y valorar las acciones necesarias para promoverlo. Objetivo: Evaluar las propiedades psicométricas de la Escala de Bienestar Psicológico para Adultos (BIEPS-A) en una muestra mexicana. Método: Se aplicó la escala BIEPS-A y la Escala de Autoestima de Rosenberg (EAR) a 188 estudiantes universitarios y 94 participantes de población general. Resultados: Un análisis paralelo detectó un factor único en la escala BIEPS-A, estructurado mediante análisis factorial exploratorio (componentes principales, rotación oblicua) que retuvo 9 reactivos y explicó el 54% de la varianza. La consistencia interna fue de aceptable (α de Cronbach = .78) a elevada (alfa ordinal = .90). El análisis de curva ROC identificó un punto de corte equivalente a la mediana (ABC = .72, p < .01) y otro al percentil 75 (ABC = .80, p < .01), y ser mujer, tener entre 18 y 25 años y bajo o leve nivel de autoestima como predictores de bajo nivel de bienestar psicológico. La escala BIEPS-A mostró validez concurrente (r = .57) y predictiva con la EAR (β = .63). Discusión y conclusiones: La escala BIEPS-A es un instrumento válido y confiable para evaluar el bienestar psicológico en población mexicana; sin embargo, las diferencias respecto a su estructura original indican la necesidad de una escala de bienestar psicológico diseñada específicamente para población mexicana.
Abstract Introduction: Psychological well-being favors the functioning of personal and social life. Valid and reliable instruments are necessary for its evaluation that allow deciding and assessing the actions necessary to promote it. Objective: To evaluate the psychometric properties of the Scale of Psychological Well-being for Adults (BIEPS-A) in a Mexican sample. Methods: The BIEPS-A scale and the Rosenberg Self-Esteem Scale (RSES) were administered to 188 university students and 94 participants from the general population. Results: A parallel analysis detected a single factor in the BIEPS-A scale, structured by exploratory factor analysis (main components, oblique rotation) that retained 9 items and explained 54% of the variance. Internal consistency ranged from acceptable (Cronbach's α = .78) to high (ordinal alpha = .90). ROC curve analysis identified a cut-off point equivalent to the median (AUC = .72, p <.01) and another to the 75th percentile (AUC = .80, p <.01). The latter identified as a woman, between 18 and 25 years old with a low or slight level of self-esteem as predictors of a low level of psychological well-being. The BIEPS-A scale showed concurrent (r = .57) and predictive (β = .63) validity with the EAR. Discussion and conclusions: The BIEPS-A scale is a valid and reliable instrument to assess psychological well-being in the Mexican population. However, the differences with respect to its original structure indicate the need for a psychological well-being scale designed specifically for the Mexican population.
RESUMEN
Resumen Introducción: Estudiantes de medicina reportan mayor ansiedad que estudiantes de otras carreras. El conocimiento sobre su bienestar psicológico es escaso. Objetivo: Identificar factores sociodemográficos y académicos predictores del nivel de ansiedad y bienestar psicológico en estudiantes mexicanos de medicina. Método: Estudio transversal de estudiantes mexicanos de medicina de primer (n = 59), tercer (n = 43) y quinto semestre (n = 59), que contestaron un cuestionario sociodemográfico, la Escala de Ansiedad de Beck, la Escala de Bienestar Psicológico para Adultos y la Escala de Evaluación de la Cohesión y la Adaptabilidad Familiar. Resultados: Las mujeres presentaron mayor ansiedad (p < 0.01). La ansiedad en hombres fue similar en los distintos semestres (p > 0.05); las mujeres de tercer y quinto semestre fueron más ansiosas que las del primero (p < 0.01). Ansiedad y bienestar psicológico correlacionaron negativamente (p < 0.001). Se identificaron los subgrupos Menor ansiedad, mayor bienestar y Mayor ansiedad, menor bienestar, y una regresión logística identificó que ser mujer (OR = 4.70) y no profesar alguna religión (OR = 2.49) son factores predictores de mayor ansiedad. Conclusiones: Las estudiantes de medicina constituyen una población de riesgo para mayor ansiedad y menor bienestar psicológico, lo que compromete su aprendizaje, calidad de vida y futuro ejercicio profesional.
Abstract Introduction: Medical students report higher levels of anxiety than students from other majors. Knowledge about their psychological well-being is scarce. Objective: To identify sociodemographic and academic factors that predict the level of anxiety and psychological well-being in Mexican medical students. Method: Cross-sectional study of Mexican medical students of first (n = 59), third (n = 43) and fifth semester (n = 59), who answered a sociodemographic questionnaire, Beck Anxiety Inventory, the Psychological Well-being Scale for adults and the Family Adaptability and Cohesion Evaluation Scale. Results: Females showed higher levels of anxiety (p < 0.01). Anxiety in males was similar in the different semesters (p > 0.05); women of third and fifth semesters were more anxious than those at first semester (p < 0.01). Anxiety and psychological well-being were negatively correlated (p < 0.001). The Less anxiety, higher level of well-being and More anxiety, lower level of well-being subgroups were characterized, and a logistic regression identified that being a woman (OR = 4.70) and not practicing any religion (OR = 2.49) are predictive factors of higher levels of anxiety. Conclusions: Female medical students constitute a population at risk for higher levels of anxiety and less psychological well-being, which compromises their learning, quality of life and future professional practice.

Abstract Introduction Anxiety and depression in pregnant women are a public health problem. Their adequate detection requires valid and reliable instruments that are also useful for prevention and treatment. Objective To identify the psychometric properties of the Hospital Anxiety and Depression Scale (HADS) in a sample of Mexican pregnant women. Method The HADS was applied to 716 pregnant women between 13 and 46 years old (M = 26.55; SD = 6.56) attended in a public hospital in Mexico City. Results With a sample of 358 participants, a parallel analysis indicated a bifactorial structure for HADS, identified by exploratory factor analysis (Factor 1: anxiety, Factor 2: depression). The factors explained 53% of the variance and correlated positively (r = .36). The global internal consistency (Cronbach's α = .81; ordinal α = .93) and by factor (anxiety: Cronbach's α = .79; ordinal α = .88; depression: Cronbach's α = .79; ordinal α = .87) was acceptable. With data from the remaining 358 participants, a confirmatory factor analysis showed an acceptable fit for the structure detected (χ2/gl = 2.72; RMSEA = .06 [IC .05, .08]; GFI = .93; AGFI = .90; TLI = .90; CFI = .92). Discussion and conclusions The Hospital Anxiety and Depression Scale has adequate psychometric properties to be used in pregnant Mexican women. Its use in routine pregnancy controls would be useful to prevent, detect, and timely treat these conditions.
Resumen Introducción La ansiedad y la depresión en gestantes representan un problema de salud pública. Su adecuada detección requiere de instrumentos válidos y confiables que también sirvan para su prevención y tratamiento. Objetivo Identificar las propiedades psicométricas de la Escala Hospitalaria de Ansiedad y Depresión (HADS) en una muestra de mujeres embarazadas mexicanas. Método Se aplicó la HADS a 716 gestantes de entre 13 y 46 años (M = 26.55; DE = 6.56), atendidas en un hospital público en la Ciudad de México. Resultados Con una muestra de 358 participantes, un análisis paralelo indicó una estructura bifactorial para la HADS, identificada mediante análisis factorial exploratorio (Factor 1: ansiedad, Factor 2: depresión). Los factores explicaron el 53% de la varianza y correlacionaron positivamente (r = .36). La consistencia interna global (α de Cronbach = .81, α ordinal = .93) y por factor (ansiedad: αde Cronbach = .79, α ordinal = .88; depresión: α de Cronbach = .79, α ordinal = .87) fue aceptable. Con los datos de las 358 participantes restantes, un análisis factorial confirmatorio mostró un ajuste aceptable para la estructura detectada (χ2/gl = 2.72; RMSEA = .06 [IC .05, .08]; GFI = .93; AGFI = .90; TLI = .90; CFI = .92). Discusión y conclusión La Escala Hospitalaria de Ansiedad y Depresión posee adecuadas propiedades psicométricas para su empleo en mujeres embarazadas mexicanas. Su uso en controles rutinarios del embarazo sería útil para prevenir, detectar y atender oportunamente estos padecimientos.
