ABSTRACT
INTRODUCCIÓN: Se ha observado desde el inicio de la pandemia cómo ha evolucionado y deteriorado la salud de los estudiantes principalmente en carreras del área de la salud, llevando a una parte de ellos a la automedicación OBJETIVO: Analizar la evidencia científica respecto a la automedicación en estudiantes del área de la salud en relación a problemas de salud mental en la pandemia COVID-19. METODOLOGÍA: Se realizó una revisión narrativa, la investigación se realizó desde abril hasta diciembre del año 2022, los textos incluidos fueron en idioma español, inglés y portugués. Se utilizaron 4 bases de datos. RESULTADOS: 4 artículos fueron identificados y rescatados, 3 latinoamericanos en específico todos de Brasil y un asiático, de universidades tanto públicas como privadas, todas las investigaciones tuvieron el denominador común COVID-19 y su correlación con automedicación solo en estudiantes universitarios del área de la salud, todas publicadas solo entre 2020 y 2022. CONCLUSIONES: Las carreras del ámbito de la salud que más se automedicaron son en orden: medicina, enfermería y farmacia. Los fármacos más utilizados fueron: ansiolíticos, antidepresivos e hipnóticos. Los trastornos de salud mental más evidenciados para la automedicación fueron ansiedad, depresión, alteración en los patrones del sueño, estrés, miedo, crisis de angustia, confusión, impotencia e ira, todas como efectos pandémicos. La automedicación es más frecuente a medida que los estudiantes van avanzando en su formación académica. Factores para la automedicación fueron problemas en el ámbito socioeconómico-familiar, falta de acceso a internet, falta de actividades prácticas, posible contagio.
BACKGROUND: Since the beginning of the pandemic, it has been observed that the health of students, especially those in health-related careers, has evolved and deteriorated, leading some to self-medication OBJECTIVE: To analyze the scientific evidence regarding self-medication of students in the health professions, in relation to mental health problems associated with the COVID-19 pandemic. METHODOLOGY: A narrative review was conducted; the research was carried out from April to December 2022 based on texts in Spanish, English, and Portuguese. 4 databases were used. RESULTS: 4 articles were identified and selected: 3 from Latin America, specifically from Brazil, and one Asian. The articles were from both public and private universities. All the investigations had the common denominator of COVID-19 and its correlation with self-medication in university students from the health professions. All were published between 2020 and 2022. CONCLUSIONS: The health professions careers that include the most self-medicating students are, in order, medicine, nursing and pharmacy. The drugs most used for self-medication are anxiolytics, antidepressants, and hypnotics. The most common mental health disorders for self-medication are anxiety, depression, altered sleep patterns, stress, fear, panic attacks, confusion, impotence, and anger; all as pandemic effects. Self-medication is more common as students' progress in their academic training. Factors for self-medication include problems in the socioeconomic-family environment, lack of internet access, lack of practical activities, and possible contagion.
ABSTRACT
With the massification of the Internet and social networks, a new form of dating violence called cyber-violence has emerged, which involves behaviors of control, humiliation, intimidation and threats towards the partner or ex-partner. Using a non-probabilistic sample of 1,001 participants aged 18 to 25 years, the present study used an ex post facto, retrospective, cross-sectional, single-group design to analyze the joint effects that beliefs associated with dating violence such as romantic love myths, jealousy, and sexism have on the victimization and perpetration of cyber-violence. The results evidenced that jealousy is involved in both Cyber-victimization and Cyber-harassment perpetrated, while sexist beliefs are only involved in perpetration. In the discussion section, it is postulated that cyber-violence is a phenomenon that is more related to the probability of aggression, but not to the probability of being a victim. Finally, limitations and implications for future research are discussed.
ABSTRACT
In December 2019, an unprecedented outbreak of the novel coronavirus disease 2019 (COVID-19), an infectious disease caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) began to spread internationally, now impacting more than 293,750,692 patients with 5,454,131 deaths globally as of January 5, 2022. COVID-19 is highly pathogenic and contagious which has caused a large-scale epidemic impacting more deaths than the severe acute respiratory syndrome (SARS) epidemic in 2002-2003 or the Middle East respiratory syndrome (MERS) epidemic in 2012-2013. Although COVID-19 symptoms are mild in most people, in those with pre-existing comorbidities there is an increased risk of progression to severe disease and death. In an attempt to mitigate this pandemic, urgent public health measures including quarantining exposed individuals and social distancing have been implemented in most states, while some states have even started the process of re-opening after considering both the economic and public health consequences of social distancing measures. While prevention is crucial, both novel agents and medications already in use with other indications are being investigated in clinical trials for patients with COVID-19. The collaboration between healthcare providers, health systems, patients, private sectors, and local and national governments is needed to protect both healthcare providers and patients to ultimately overcome this pandemic. The purpose of this review is to summarize the peer-reviewed and preprint literature on the epidemiology, transmission, clinical presentation, and available therapies as well as to propose a preventive strategy to overcome the present global pandemic.
ABSTRACT
OBJECTIVE: To investigate the association between different versions of a provegetarian food pattern (FP) and micronutrient inadequacy. DESIGN: Cross-sectional analysis. Dietary intake was assessed at baseline through a validated 136-item FFQ. Participants were classified according to groups of different versions of a provegetarian FP: overall, healthful and unhealthful. The prevalence of inadequate intake of vitamins B1, B2, B3, B6, B12, C, A, D, E, folic acid, Zn, I, Se, Fe, Ca, K, P, Mg and Cr was evaluated using the estimated average requirement (EAR) cut-point method and the probabilistic approach. Logistic regression analyses were conducted to estimate the probability of failing to meet EAR for either ≥ 3 or ≥ 6 micronutrients. SETTING: Seguimiento Universidad de Navarra (SUN) cohort. PARTICIPANTS: 17 825 Spanish adults. RESULTS: Overall, subjects in the highest group of the unhealthful provegetarian FP had the highest prevalence of inadequate dietary intake for every vitamin and mineral, compared to those in the lowest group. The adjusted OR of failing to meet ≥ 3 EAR (highest v. lowest group) was 0·65 (0·54, 0·69) for the overall, 0·27 (0·24, 0·31) for the healthful and 9·04 (7·57, 10·4) for the unhealthful provegetarian FP. CONCLUSION: A higher adherence to an overall and healthful provegetarian FP was inversely associated with the risk of failing to meet EAR values, whereas the unhealthful version was directly associated with micronutrient inadequacy. Provegetarian FP should be well planned, prioritising nutrient-dense plant foods and minimising ultra-processed and unhealthy ones.
ABSTRACT
Introducción: La salud visual es de vital importancia para el individuo, habiendo una mayor incidencia de oftalmopatías sobre los 50 años. Pese a su impacto sanitario, Chile carece de estudios epidemiológicos suficientes. La gran variabilidad de sus presentaciones hace importante conocer cuales ameritan el tratamiento intrahospitalario. Objetivo: Describir las principales causas de egresos hospitalarios por enfermedades del ojo y sus anexos en el Hospital Regional Guillermo Grant Benavente entre los años 2018 y 2021. Materiales y métodos: Estudio ecológico que analizó 1764 egresos hospitalarios por enfermedades del ojo y sus anexos del Hospital Guillermo Grant Benavente entre los años 2018 y 2021. Los datos corresponden al Departamento de Estadísticas e Información en Salud (DEIS). Resultados: Las patologías más prevalentes fueron: Trastornos De La Coroides Y De La Retina (33%) (TCR) Trastornos Del Cristalino (14,7%), Trastornos De La Esclerótica, Córnea, Iris Y Cuerpo Ciliar (10,2). Trastornos Del Párpado, Aparato Lagrimal Y Órbita (12,7%) (TPAO) Esta última con diferencias estadísticamente significativas para el sexo. Conclusión: Se ve una disminución de la atención hospitalaria desde el año 2020 debido a la pandemia del virus SARS-COV-2. No hay diferencias por sexo, excepto para la TPAO, similar a lo visto en la literatura. La acumulación de oftalmopatías en el rango de población adulta y adulta mayor, refleja un envejecimiento poblacional. Se reconoce además a los TCR como la patología con mayor incidencia. El estudio contribuye a la epidemiologia local, aportando a la falta de conocimientos actualizados, describiendo los diagnósticos más frecuentes de la especialidad.
Introduction: Eye care is vital for the individual, with a higher incidence of ophthalmopathy over 50 years. Despite its health impact, Chile lacks sufficient epidemiological studies. The great variability of their presentations makes it important to know which ones merit in-hospital treatment. Objective: To describe the main causes of hospital discharges for eye diseases and its adnexa at the Guillermo Grant Benavente Regional Hospital between 2018 and 2021. Material and methods: An ecological descriptive study that analyzed 1,764 hospital discharges for eye diseases and its adnexa from the Hospital Guillermo Grant Benavente between the years 2018 and 2021. The data corresponds to the Department of Statistics and Health Information (DEIS). Results: The most prevalent pathologies were: Disorders of the Choroid and Retina (33%) (TCR), Disorders of the Lens (14.7%), Disorders of the Sclera, Cornea, Iris, and Ciliary Body (10.2). Disorders of the Eyelid, Lacrimal Apparatus and Orbit (12.7%) (TPAO) The latter with statistically significant differences for sex. Conclusion: A decrease in hospital care is seen since 2020 due to the SARS-COV-2 virus pandemic. There are no differences by sex, except for PPAO, similar to what has been seen in the literature. The accumulation of ophthalmopathy in the range of the adult population and older adults, reflects an aging population. TCR is also recognized as the pathology with the highest incidence. The study contributes to the local epidemiology and the lack of updated knowledge, describing the most frequent diagnoses of the specialty.

Aquaculture activities in southern Chile demand floating devices to produce electricity powered by diesel generators. It has been recently proposed to replace this fuel with propane. However, little is known about the behaviour and possible environmental impacts of an accidental release of propane underwater. In this study we evaluated the impact of water temperature and salinity on the saturation and further release of propane under controlled laboratory experiments. Results showed that under extreme environmentally relevant scenarios (high and low temperature and salinity), propane saturated the water more quickly. However, while it is important to consider that saturation times can be similar (â¼2 h), the magnitudes of propane dissolved can be different. Experiments showed that cold waters (5 °C) propane is dissolved twice than warm waters (20 °C). Residence time was more affected by water temperature and almost independent of water salinity. Propane may take at least 2 days to be released from waters (around 90% of the initial amount dissolved under laboratory conditions). Additionally, we evaluated the impact on dissolved oxygen displacement and the embryotoxicity of the dissolved fraction by using Zebrafish Embryo Toxicity Assay. Results showed that dissolved oxygen was quickly removed. However, the levels of dissolved oxygen were promptly recovered in the studied systems. We also observed that propane can generate genotoxic effects (3-10% mortality), but after 2 days the system can be almost free of propane and the effects may become much lower. Comparatively with the literature, propane showed to be less toxic than diesel and it is a viable and less environmentally hazardous replacement for diesel.

The internalization of multi-cellular tissues is a key morphogenetic process during animal development and organ formation. A good example of this is the initial stages of vertebrate central nervous system formation whereby a transient embryonic structure called the neural plate is able to undergo collective cell rearrangements within the dorsal midline. Despite the fact that defects in neural plate midline internalization may result in a series of severe clinical conditions, such as spina bifida and anencephaly, the biochemical and biomechanical details of this process remain only partially characterized. Here we review the main cellular and molecular mechanisms underlying midline cell and tissue internalization during vertebrate neural tube formation. We discuss the contribution of collective cell mechanisms including convergence and extension, as well as apical constriction facilitating midline neural plate shaping. Furthermore, we summarize recent studies that shed light on how the interplay of signaling pathways and cell biomechanics modulate neural plate internalization. In addition, we discuss how adhesion-dependent cell-cell contact appears to be a critical component during midline cell convergence and surface cell contraction via cell-cell mechanical coupling. We envision that more detailed high-resolution quantitative data at both cell and tissue levels will be required to properly model the mechanisms of vertebrate neural plate internalization with the hope of preventing human neural tube defects.

It is not currently known which individuals with chronic Chagas disease (ChD) will develop cardiopathy in a determined period and which will be maintained asymptomatic with normal routine laboratory tests all their lives. The parasite burden is a factor that could explain this different evolution. The objective of this study was to quantify Trypanosoma cruzi burden by real-time PCR in blood (qPCR-B) and dejections of triatomines fed by xenodiagnosis (qPCR-XD) in 90 individuals with chronic ChD untreated, classified according to XD results and the presence or absence of cardiopathy. All individuals came from hyperendemic areas of Chile and participated in the study under Informed Consent. The standard qPCR curves for qPCR-B and qPCR-XD were elaborated with a mixture of known concentrations of T. cruzi strains, performing DNA serial dilutions (1/10) with a dynamic range between 105 and 10-1 parasite equivalents/mL. The TaqManâ detection system was applied in a Stratagene Mx3000P thermocycler (Agilent Technologies, USA) with cruzi 1 and cruzi 2 satellite primers. 22.2% and 15.6% of cases with cardiopathy or without cardiopathy were XD positive. There was no significant difference between the groups. The positivity of qPCR-B and qPCR-XD in the positive XD group was 82.35% and 100%, respectively, while in the negative XD group was 55.26% and 42.10%, respectively. A superior qPCR value in chronic ChD patients with and without cardiopathy was determined for qPCR in cases with positive XD and positive qPCR-XD. The receiver operating characteristic (ROC) curve analyses show better accuracy for detecting parasite burden (area under the curve, AUC) for qPCR-XD in comparison to qPCR-B. That is to say, major performance in DNA samples obtained of positive XD (gold standard for viable T. cruzi) detected and quantified by qPCR-XD. A high percentage of cases with XD and qPCR-XD positive (80-100%) have result concordant with qPCR-B. In absence of XD, future challenges are especially related to the low parasitic load of chronic ChD patients treated with trypanocidal drugs and post-therapy parasitological evaluations by qPCR-B. Finally, no statistically significant differences were found between presence or absence of cardiopathy and XD, qPCR-B or qPCR-XD.

Se sabe que un déficit severo de yodo durante la etapa prenatal y postnatal temprana provoca un severo retraso mental. Nos interesó estudiar si un déficit moderado de este micronutriente también altera la expressión del potencial genético del coeficiente intelectual. Se tomaron 90 escolares de un área con una prevalencia de 30% de bocio de los cuales 42 tenían bocio y 48 no tenían bocio. Se evaluó el estado nutritivo, el nivel socioeconómico (NSE) y se consultó sobre patología perinatal. Se evaluó el coeficiente intelectual (CI) a través de WISC-R la coordinación visomotriz por Bender Koppitz y la destreza manual mediante una prueba diseñada ad-hoc. No se encontraron diferencias en NSE, estado nutritivo ni en patología perinatal entre ambos grupos. Los escolares sin bocio tuvieron puntajes significativamente más altos de CI que los con bocio (88,9 + ou - 11,5 vs 84,5 + ou - 10,4 respectivamente). No se encontraron diferencias significativas en los otros test empleados. Estos resultados indicarían que un déficit moderado también altera el CI. Se discuten las consecuencias de estos hallazgos

En un seguimiento longitudinal de hijos de adolescentes de clase media baja se analizó su crecimiento y desarrollo en los primeros 18 meses de vida, en comparación con hijos de adultas de semejante nivel socioeconómico. Se encontró mayor déficit estatural en los hijos de adolescentes, sin mayor déficit de peso para la estatural, al compararlos con los hijos de adultas. Se discuten los factores etiológicos, que pudieran participar en este retraso estatural
