Objetivo. Describir la ocurrencia de eventos potencialmente traumáticos (EPT) en estudiantes de preparatoria, medir la sintomatología postraumática subumbral en quienes aún sufren repercusiones de un EPT y asociar la sintomatología con variables sociodemográficas y características del EPT. Material y métodos. Estudio transversal analítico realizado en un muestra por conveniencia de 1 000 estudiantes de tres preparatorias del Estado de México. Se aplicó la Escalapara Estrés Postraumático en Universitarios Mexicanos. Se evaluó la presencia de síntomas y su frecuencia; la asociación con variables explicativas se realizó con modelos de regresión logística y cuantílica, respectivamente. Resultados. 80% reportó un EPT. De éstos, 79% aún sufría repercusiones actuales y casi la mitad de ellos presentó sintomatología. El sexo, número de eventos y características del EPT (cambios percibidos y gravedad) se encontraron asociados. Conclusiones. Los resultados sugieren intervenir tempranamente para disminuir el riesgo de desarrollar un trastorno.

Background: In recent decades, noise pollution has become a significant concern, especially in sensitive environments such as hospitals. For neonates in neonatal intensive care units (NICUs), noise can have serious implications due to their underdeveloped auditory and physiological systems. Elevated noise levels in NICUs have been linked to disruptions in normal physiological parameters and can negatively impact both neonatal health and staff performance. Aim: To identify and quantify sources of noise in the intensive care unit of a hospital NICU. Methods: An observational study was conducted to assess noise levels in a Mexican NICU. Noise measurements were taken across 22 different scenarios identified as potential noise sources, during all three shifts to capture variations throughout the day. Results: Noise levels ranged from 45 to 70 decibels (dB). The nursing shift change was identified as the scenario with the highest noise level, while the paper dispenser area recorded the lowest. These findings highlight specific times and locations within the NICU where noise reduction interventions should be focused. Conclusions: Targeted noise control strategies, especially during shift changes, could significantly improve the acoustic environment in NICUs, helping to safeguard neonatal well‐being and staff performance.

Background/Objectives: Eating behavior disorders (EBDs) are a public health concern among undergraduate students. Evidence suggests that certain health-related academic environments may be associated with heightened psychological vulnerability. Hence, we aimed to evaluate the association between nursing education and the risk of EBDs and to assess whether self-esteem and anxiety mediate this relationship. Methods: A cross-sectional analytical study was conducted between July and August 2023 among 433 undergraduate students from two public universities in Hidalgo, Mexico. The sample included 209 nursing students and 224 peers from non-health-related programs. Self-esteem, anxiety, and EBD risk were assessed using the Rosenberg Self-Esteem Scale, Hamilton Anxiety Rating Scale, and Eating Attitudes Test-26, respectively. Logistic regression and counterfactual mediation analyses were performed, adjusting for age, sex, family income, and year of study. Results: Nursing students showed higher odds of low self-esteem (aOR = 1.64; 95% CI: 1.06–2.53), anxiety (aOR = 2.06; 95% CI: 1.25–3.37), and EBDs risk (aOR = 2.37; 95% CI: 1.37–4.09) compared with non-health peers. Mediation analyses revealed significant indirect effects through self-esteem (aOR = 1.20; 95% CI: 1.03–1.38) and anxiety (aOR = 1.14; 95% CI: 1.01–1.29). Conclusions: Nursing education was independently associated with a higher risk of EBDs, with statistical mediation analyses indicating that differences in self-esteem and anxiety may help characterize this association. Self-esteem exerted a slightly stronger indirect effect, suggesting that negative self-evaluation may represent a more proximal psychological process rather than a causal determinant.

The increase in the older adult population is accompanied by the growing responsibility of performing caregiving functions as older adults. People over 60 years of age require physical and emotional efforts that could affect their quality of life as caregiver burden is known to be a common phenomenon in people who have individuals to care for. The present article aims to identify how this burden is related to the quality of life of older adult caregivers. A quantitative study of non-experimental correlational design was conducted. The sample consisted of 134 people over 60 years of age residing in the State of Hidalgo. The Zarit scale was used to measure caregiver burden and the Quality of Life of the Informal Caregiver instrument to assess quality of life. The results indicate that there is a statistically significant relationship (r=.726**, p=<0.001) between perceived caregiver burden and lower quality of life, especially in dimensions such as physical health, emotional and social status. The findings show that 89.5% of caregivers experience intense overload, which negatively affects their well-being. In conclusion, the study highlights the urgent need to develop public policies and support strategies to alleviate the burden of older adult caregivers in order to improve their quality of life and promote healthy aging.

Background: A positive attitude toward research is crucial for the development of evidence‐based practice (EBP). Despite its importance, many medical and nursing students display negative or indifferent attitudes toward research. Aim: The aim of this study was to assess the attitudes toward research among nursing interns and medical residents in a pediatric hospital in Mexico. Methods: After obtaining approval from the hospital’s ethics committee, a structured and validated questionnaire was administered to nursing interns and medical residents ( n = 198) who had signed informed consent. The results were categorized into four areas: research skills, barriers to research, and positive and negative perceptions of research. Descriptive and inferential statistics were performed (ANOVA, Student’s t ‐test, and Pearson correlation), with a significance level of p < 0.05, following a prior normality test using the Kolmogorov–Smirnov test. Results: The majority of participants considered writing skills and knowledge of APA formatting to be essential for conducting research. However, they also identified significant barriers, such as lack of knowledge and limited support from faculty. Participants exhibited low to moderate attitudes toward research. Conclusions: Attitudes toward research were generally poor in this study group. Educational institutions and hospitals should implement strategies to foster a supportive and research‐driven environment, which could enhance the training of future professionals and ultimately improve the quality of healthcare.

The anxiety, as an adaptive emotion, can motivate individuals to seek solutions and improve their performance, but when it reaches pathological levels, it significantly affects daily life. This descriptive review article narrates the importance of studying anxiety through animal models at the preclinical level, highlighting its relevance in understanding the neurobiology and development of effective treatments. A search for updated scientific information was conducted in Pubmed, Web of Science, Embase, Cochrane Library, and other databases. It discusses experimental models of conditioned and unconditioned responses used to replicate characteristics of these disorders in laboratory animals, which must possess face, construct, and predictive validity. The limitation of these models to fully replicate the complete human experience of anxiety is emphasized, as well as the physiological and behavioral differences between species. Despite their limitations, animal models remain valuable tools for understanding and treating anxiety, although more research is needed to improve their validity and clinical applicability.
