ABSTRACT

BACKGROUND: There are no trend studies on various health risk behaviours among adolescents in Uruguay. Therefore, this study looked at trends in a number of health-risky behaviours among adolescents in Uruguay from three separate surveys. METHODS: Data from 9272 adolescents (age range: 11-16 years), who took part in three cross-sectional national in-school surveys in Uruguay in 2006, 2012 and 2019 were analysed. A self-administered survey was used to evaluate 24 health risk behaviours. By using logistic regression analyses to treat the study year as a categorical variable and adjusting food insecurity and age, linear trends were examined. RESULTS: We found a significant increase in the prevalence of being overweight, having obesity, inadequate fruit intake, sedentary behaviour in leisure-time, physical inactivity, bullying victimisation, loneliness, suicidal ideation, and sexual activity. We found a significant decrease in current cigarette use, physical fighting and current alcohol use. Among males, a significant increase of non-condom use, and a decrease in current other tobacco use (other than cigarettes), being physically attacked and the number of sexual partners. Among females, we found an increase in food insecurity, trouble from alcohol use, multiple sexual partners, and sleep problems. CONCLUSION: Overall, from 2006 to 2019, there was a decrease in seven health risk behaviours among boys and/or girls. Among boys, there was an increase in 10 health risk behaviours and among girls, 15 health risk behaviours increased, highlighting adolescent girls' greater vulnerability, thereby perpetuating further gendered health inequalities. In Uruguay, school health programmes for adolescents are recommended.

ABSTRACT

In the department of Boyacá, Colombia, agriculture stands as one of the primary economic activities. However, the escalating utilization of pesticides within this sector has sparked concern regarding its potential correlation with elevated risks of genotoxicity, chromosomal alterations, and carcinogenesis. Furthermore, pesticides have been associated with a broad spectrum of genetic polymorphisms that impact pivotal genes involved in pesticide metabolism and DNA repair, among other processes. Nonetheless, our understanding of the genotoxic effects of pesticides on the chromosomes (as biomarkers of effect) in exposed farmers and the impact of genetic polymorphisms (as susceptibility biomarkers) on the increased risk of chromosomal damage is still limited. The aim of our study was to evaluate chromosomal alterations, chromosomal instability, and clonal heterogeneity, as well as the presence of polymorphic variants in the GSTP1 and XRCC1 genes, in peripheral blood samples of farmers occupationally exposed to pesticides in Aquitania, Colombia, and in an unexposed control group. Our results showed statistically significant differences in the frequency of numerical chromosomal alterations, chromosomal instability, and clonal heterogeneity levels between the exposed and unexposed groups. In addition, we also found a higher frequency of chromosomal instability and clonal heterogeneity in exposed individuals carrying the heterozygous GSTP1 AG and XRCC1 (exon 10) GA genotypes. The evaluation of chromosomal alterations and chromosomal instability resulting from pesticide exposure, combined with the identification of polymorphic variants in the GSTP1 and XRCC1 genes, and further research involving a larger group of individuals exposed to pesticides could enable the identification of effect and susceptibility biomarkers. Such markers could prove valuable for monitoring individuals occupationally exposed to pesticides.

Introduction: Centralizing higher education studies in Montevideo entails economic expenses, family uprooting, and loss of human resources for families living in the interior of Uruguay. The training of pediatric specialists outside the capital city began in the 1980s. In recent years, this innovations has been reinforced by adding learning scenarios, teachers, didactic resources, and evaluations. Objective: to describe the experience of decentralizing the teaching of pediatric specialists between 2007 and 2021 in Maldonado, Paysandú, Rivera, and Salto. Method: Descriptive study, including postgraduate students of pediatris who completed their training in Maldonado, Paysandú, Rivera, and Salto between 2007 and 2021. The study describes the number of specialists trained, personal or family characteristics that influenced the decision to take the course in the interior, academic performance, place of professional practice, and available teaching staff. Results: during the study period, 88 students undertook postgraduate studies in the evaluated cities, 33 of which studied in a residency program. Of these, 78 were native to or residents of the area. Fifty six pediatricians graduated, 18 were still enrolled, and 4 dropped out. A variable percentage of the course's mandatory components were conducted in the interior. Average time to complete all mandatory activities was 3.3 years. Sixty graduates practice in the place of training or in nearby cities. Paysandú and Salto have 34 hours of teaching per week; Maldonado has 6 hours per week and honorary teachers. Rivera has honorary teachers/tutors. Conclusions: the decentralization of pediatric teaching is a significant achievement for inland cities in the interior of the country, as it allows them to train their own human resources, enabling them to settle in these cities. There is a need to improve the offer of curricular activities and teaching hours.

ABSTRACT

The aim of this research is to describe the evolution of the pandemic in a school context, following the introduction of school nurses into the educational setting. BACKGROUND: The first wave of COVID-19 in Spain prevented social interaction by imposing lockdowns on the population. All non-essential activities, including face-to-face education, were interrupted, affecting the school-aged population during the second and third trimester of the 2019/2020 school year. Schools are places where prevention, identification and case management measures should be rapidly implemented. METHODS: This is a prospective and descriptive study using a quantitative method to study the school population of Granada and its province during the school year 2020/2021, from September 2020 to May 2021. The study participants were all schools under the jurisdiction of the Territorial Delegation of Education of Granada, whether public, private, state-subsidised or charter schools, including all educational stages. RESULTS: The confirmation rate in Granada city (11.2%), in contrast to the Andalusian average (6.9%), places Granada as the province with the highest incidence rate. The infection rates among teachers show the same confirmation rate as the general population of Granada (9%); however, among students this rate is lower (7%). There is a higher incidence of outbreaks taking place outside school and a lower incidence of outbreaks occurring within the school environment. Both partial and total outbreaks are more frequent in early childhood education. CONCLUSION: The early identification and management of reported suspected cases of COVID-19 in schools is proving effective in preventing infection in the school population, achieving good pandemic control in schools, and reducing the number of outbreaks and people affected. Schools have been confirmed to be safe. Establishing screening for asymptomatic schoolchildren could be a tool to improve control in schools.

ABSTRACT

To develop software to stimulate cognitive functions of attention, memory, reasoning, planning, language, and perception in Mexican older adults, and to evaluate the usability of software based on system utility, information quality, and interface quality.For the development of the cognitive stimulation software, an inductive-deductive methodology was used in three stages: Analysis (system requirements), design and coding (cognitive stimulation software), evaluation (usability results).The usability of the software was assessed in 89 older adults between the ages of 60 and 84 years, through a usability questionnaire with evidence of reliability and validity.Eight exercises about attention, seven on memory, three on reasoning, one about planning and language, and two on perception were developed. We evaluated the usability of the developed software using the Computer System Usability Questionnaire, obtaining medium-high usability in 76.2% of the participants regarding the system utility, in 77.7% concerning the information quality and, in 84.2% in the interface quality.The software was developed considering aspects of usability and based on changes and losses associated with aging, as well as on the stimulation of cognitive functions related to instrumental activities of daily living, including exercises based on traditional pencil-paper exercises.

ABSTRACT

Resumen La meningitis por Mycobacterium tuberculosis es infrecuente en pediatría y su diagnóstico definitivo representa un desafío clínico. Presentamos el caso de un lactante de dos años, que presentó un cuadro de meningitis crónica. Se logró el diagnóstico tras la sospecha imagenológica y la confirmación tras la búsqueda seriada del complejo M. tuberculosis por RPC en LCR y en biopsia de tejido cerebral. A pesar de sus complicaciones, el paciente respondió favorablemente al tratamiento antituberculoso. En Chile, la tuberculosis es infrecuente en niños y los síntomas son generalmente inespecíficos. Los hallazgos en RM cerebral asociados a alteraciones del LCR permiten sospechar el compromiso meníngeo precozmente. Se recomienda iniciar el tratamiento antituberculoso empírico ante la sospecha, ya que mejora el pronóstico. A pesar de los avances diagnósticos y terapéuticos, la meningitis tuberculosa sigue teniendo una alta tasa de complicaciones y un pronóstico ominoso.


Abstract Mycobacterium tuberculosis meningitis is rare in the pediatric population and its definitive diagnosis represents a clinical challenge. We present the case of a 2-year-old infant with chronic meningitis. Diagnosis was accomplished by suggestive radiological findings and serial search for M. tuberculosis complex by real-time polymerase chain reaction (qPCR) in cerebrospinal fluid (CSF) and in brain tissue. Despite the complications, the patient evolved favorably with the tuberculosis treatment. In Chile, tuberculosis is a rare disease in children and symptoms are generally nonspecific. Brain MRI findings associated with CSF alterations allow early suspicion of MTBC. Start of empirical antituberculosis treatment upon suspicion is recommended given it is associated with better prognosis. Despite diagnostic and therapeutic advances, MTBC continues to have a high complication rate and an ominous prognosis.

ABSTRACT

Liver fibrosis is a complex process characterized by the excessive accumulation of extracellular matrix (ECM) and an alteration in liver architecture, as a result of most types of chronic liver diseases such as cirrhosis, hepatocellular carcinoma (HCC) and liver failure. Maresin-1 (MaR1) is derivative of ω-3 docosahexaenoic acid (DHA), which has been shown to have pro-resolutive and anti-inflammatory effects. We tested the hypothesis that the application of MaR1 could prevent the development of fibrosis in an animal model of chronic hepatic damage. Sprague-Dawley rats were induced with liver fibrosis by injections of diethylnitrosamine (DEN) and treated with or without MaR1 for four weeks. In the MaR1-treated animals, levels of AST and ALT were normalized in comparison with DEN alone, the hepatic architecture was improved, and inflammation and necrotic areas were reduced. Cell proliferation, assessed by the mitotic activity index and the expression of Ki-67, was increased in the MaR1-treated group. MaR1 attenuated liver fibrosis and oxidative stress was induced by DEN. Plasma levels of the pro-inflammatory mediators TNF-α and IL-1ß were reduced in MaR1-treated animals, whereas the levels of IL-10, an anti-inflammatory cytokine, increased. Interestingly, MaR1 inhibited the translocation of the p65 subunit of NF-κB, while increasing the activation of Nrf2, a key regulator of the antioxidant response. Finally, MaR1 treatment reduced the levels of the pro-fibrotic mediator TGF-ß and its receptor, while normalizing the hepatic levels of IGF-1, a proliferative agent. Taken together, these results suggest that MaR1 improves the parameters of DEN-induced liver fibrosis, activating hepatocyte proliferation and decreasing oxidative stress and inflammation. These results open the possibility of MaR1 as a potential therapeutic agent in fibrosis and other liver pathologies.

ABSTRACT

Background: Schiff bases are synthetically accessible compounds that have been used in medicinal chemistry. Methods & results: In this work, 27 Schiff bases derived from diaminomaleonitrile were synthesized in high yields (80-98%). Molecular docking studies suggested that the Schiff bases interact with the catalytic site of cruzain. The most active cruzain inhibitor, analog 13 (IC50 = 263 nM), was predicted to form an additional hydrophobic contact with Met68 in the binding site of the enzyme. A strong correlation between the IC50 values and ChemScore binding energies was observed (R = 0.99). Kernel-based 2D quantitative structure-activity relationship models for the whole dataset yielded sound correlation coefficients (R2 = 0.844; Q2 = 0.719). Conclusion: These novel and potent cruzain inhibitors are worthwhile starting points in further Chagas disease drug discovery programs.

ABSTRACT

This article reports on the first attempt towards investigating the leaching rates in the human gastrointestinal (GI) tract of plastic-borne contaminants that can be ingested accidentally using physiologically relevant body fluids. Oral bioaccessibility under fasted and fed states was determined in dynamic mode exploiting an automatic flow setup. The flow system is able to mimic the fast uptake of the released species from the polymeric matrix by absorption in the human digestive system by the in-line removal of the leached species. Complex GI extractants based on the Unified Bioaccessibility Method (UBM, fasted state) and Versantvoort test (fed-state) were brought through a microplastic-loaded metal microcolumn for semi-continuous leaching of plasticizers (phthalic acid ester congeners) and monomer/antioxidant species (bisphenol A, BPA) followed by in-line solid-phase extraction and clean-up of GI extracts prior to liquid chromatography analysis. The temporal extraction profiles were fitted to a first-order kinetic model for the estimation of maximum bioaccessibility pools and apparent leaching rates. Among all studied contaminants, only BPA, dimethylphthalate and diethylphthalate were appreciably released under dynamic GI conditions from high-density polyethylene pellets (average size of 110 µm), with average bioaccessibility values spanning from 51 to 84% and 48 to 87% for UBM and Versantvoort methods, respectively. No statistically significant differences in oral bioaccessibility pools were found under fed- and fasted-state dynamic extractions. The apparent kinetic constants under the fed state were greater by ≥30% as a consequence of the effect of the larger amounts of bile salts and digestive enzymes in the Versantvoort test on the leaching rates. The estimated average daily intake, in which bioaccessibility data are contemplated, indicated that plastic materials exceeding 0.3% (w/w) BPA might pose real risks to human health.

ABSTRACT

Electrical burns are capable of damaging cells through both thermal and nonthermal mechanisms. The complexity of these wounds, the deterioration in time, and the conversion during the first days make managing them a challenge. Negative pressure wound therapy (NPWT) is a technology that can be used as a tool to improve outcomes in patients with burns in the acute and reconstructive phases of the treatment. We describe 2 cases in which we apply this technology in electrical injuries. We present 2 cases of patients with electrical burns who underwent NPWT with instillation (NPWTi) with saline solution in the acute phase, to block the conversion of the burn and to improve the granulation tissue and in the reconstructive phase, as a tool to improve the grafts take. Both patients showed early formation of granulation tissue adequate for surgical reconstruction, and neither of them presented loss of skin grafts. In the acute phase, NPWT with instillation when applied in these patients showed fast formation of granulation tissue adequate for early reconstruction, whereas NPWT in the reconstructive phase when applied to bolster grafts showed improvements in grafts take. NPWT is a useful tool to support the surgical management of the electrical injuries during the acute phase to prepare the wound for early reconstruction and after the skin grafts reconstruction to improve the grafts take.

ABSTRACT

Liver fibrosis is a complex process associated to most types of chronic liver disease, which is characterized by a disturbance of hepatic tissue architecture and the excessive accumulation of extracellular matrix. Resolvin E1 (RvE1) is a representative member of the eicosapentaenoic omega-3 lipid derivatives, and is a drug candidate of the growing family of endogenous resolvins. Considering the aforementioned, the main objective of this study was to analyze the hepatoprotective effect of RvE1 in a rat model of liver fibrosis. Male Sprague-Dawley rats received diethylnitrosamine (DEN, 70 mg/mg body weight intraperitoneally (i.p)) as an inductor of liver fibrosis once weekly and RvE1(100 ng/body weight i.p) twice weekly for four weeks. RvE1 suppressed the alterations induced by DEN, normalizing the levels of alanine aminotransferase (ALT), albumin, and lactate dehydrogenase (LDH), and ameliorated DEN injury by decreasing the architecture distortion, inflammatory infiltration, necrotic areas, and microsteatosis. RvE1 also limited DEN-induced proliferation through a decrease in Ki67-positive cells and cyclin D1 protein expression, which is related to an increase of the levels of cleaved caspase-3. Interestingly, we found that RvE1 promotes higher nuclear translocation of nuclear factor κB (NF-κB)p65 than DEN. RvE1 also increased the levels of nuclear the nuclear factor erythroid 2-related factor 2 (Nrf2), but with no antioxidant effect, measured as an increase in glutathione disulfide (GSSG) and a decrease in the ratio of glutathione (GSH)/GSSG. Taken together, these results suggest that RvE1 modulates the fibrogenesis, steatosis, and cell proliferation in a model of DEN induced fibrosis.

ABSTRACT

El lupus eritematoso sistémico es una enfermedad que causa un gran número de complicaciones de origen psicológico; estas pueden llevar a patrones inadecuados de conducta que pueden poner en riesgo la vida de los pacientes como el síndrome de Rapunzel. Se describen los elementos clínicos y diagnósticos de este síndrome mediante el caso de una paciente femenina de 25 años de edad, con diagnóstico de lupus eritematoso sistémico. Acude a consulta con manifestaciones clínicas e imagenológicas que permiten llegar al diagnóstico de síndrome de Rapunzel como complicación psicológica en el curso del lupus eritematoso sistémico. Se procede a realizar la intervención quirúrgica donde se halló una masa tumoral constituida por cabello humano. En la actualidad, la paciente se mantiene en seguimiento por las especialidades de reumatología, psiquiatría y psicología, y su recuperación y evolución han sido satisfactorias. El lupus eritematoso condiciona conductas que pueden ser perjudiciales para la salud de los pacientes. Es importante la identificación precoz de conductas como la tricotilomanía y el seguimiento psicológico especializado en pacientes con esta enfermedad(AU)

ABSTRACT

Drug resistance is a serious problem in cancer, viral, bacterial, fungal and parasitic diseases. Examination of crystal structures of protein-drug complexes is often not enough to explain why a certain mutation leads to drug resistance. As an example, the crystal structure of the kinase inhibitor dasatinib bound to the Abl1 kinase shows a hydrogen bond between the drug and residue Thr315 and very few contacts between the drug and residues Val299 and Phe317, yet mutations in those residues lead to drug resistance. In the first case, it is tempting to suggest that the loss of a hydrogen bond leads to drug resistance, whereas in the other two cases it is not known why mutations lead to drug resistance in the first place. We carried out extensive molecular dynamics (MD) simulations and free energy calculations to explain drug resistance to dasatinib from a molecular point of view and show that resistance is due to a multitude of subtle effects. Importantly, our calculations could reproduce the experimental values for the binding energies upon mutations in all three cases and shed light on their origin.

ABSTRACT

Maresin-1 (MaR1) is a specialized pro-resolving mediator, derived from omega-3 fatty acids, whose functions are to decrease the pro-inflammatory and oxidative mediators, and also to stimulate cell division. We investigated the hepatoprotective actions of MaR1 in a rat model of liver ischemia-reperfusion (IR) injury. MaR1 (4 ng/gr body weight) was administered prior to ischemia (1 h) and reperfusion (3 h), and controls received isovolumetric vehicle solution. To analyze liver function, transaminases levels and tissue architecture were assayed, and serum cytokines TNF-α, IL-6, and IL-10, mitotic activity index, and differential levels of NF-κB and Nrf-2 transcription factors, were analyzed. Transaminase, TNF-α levels, and cytoarchitecture were normalized with the administration of MaR1 and associated with changes in NF-κB. IL-6, mitotic activity index, and nuclear translocation of Nrf-2 increased in the MaR1-IR group, which would be associated with hepatoprotection and cell proliferation. Taken together, these results suggest that MaR1 alleviated IR liver injury, facilitated by the activation of hepatocyte cell division, increased IL-6 cytokine levels, and the nuclear localization of Nrf-2, with a decrease of NF-κB activity. All of them were related to an improvement of liver injury parameters. These results open the possibility of MaR1 as a potential therapeutic tool in IR and other hepatic pathologies.

ABSTRACT

INTRODUCTION AND OBJECTIVES: The omega-3 fatty acids (ω3), EPA and DHA, have been described for their beneficial effects on metabolism and inflammation. In addition, they are interesting tools in the treatment of acute liver disease. This investigation was conducted to assess the effect of EPA+DHA administration before partial ischemia (IR) on survival and liver injury. MATERIALS AND METHODS: Male Sprague-Dawley rats were supplemented for 7 days with ω3 [EPA (270mg/kg) and DHA (180mg/kg)]; controls received saline solution. After EPA+DHA supplementation, liver IR was induced by temporarily occluding the blood supply for 1h, followed up by 48h of reperfusion. Control animals were subjected to sham laparotomy. RESULTS: Previous to IR, the EPA+DHA administration improved the rate and prolonged the survival time by decreasing the AST and ALT levels and improving liver degenerative changes generated by the IR, which decreased TNF-α and IL-1ß. In addition, IL-10 increased at 20h with a tendency to normalize at 48h. The IR group had no differences in the IL-10 levels compared to controls.

ABSTRACT

El país se encuentra implementando la historia clínica electrónica nacional (HCEN) en un escenario donde cada prestador de salud está obligado a contar con una historia clínica electrónica (HCE) y a intercambiar datos clínicos de las personas que son asistidas. Este trabajo tiene como objetivo revisar y discutir los aspectos vinculados a la confidencialidad y privacidad de los datos de la historia clínica de las personas en este nuevo escenario. Se comienza por definir un marco conceptual respecto a la HCE y al sistema de HCEN. Se hace una revisión del encuadre jurídico actual respecto a esta temática, haciendo énfasis en conceptos generales de la privacidad y abordando aspectos específicos vinculados al acceso y la custodia de las historias clínicas. La implementación del sistema HCEN representa a priori varios beneficios, tanto desde el punto de vista asistencial (paciente y médico) como desde el punto de vista del sistema nacional de información en salud. Para llevar adelante la implementación de la HCEN, fue necesario regular algunos aspectos jurídicos, esto es, los derechos y las obligaciones emergentes del nuevo sistema. (AU)


The national electronic health record (HCEN) is being implemented in our country, within the framework of a scenario whereby each one of the health providers is obliged to have an electronic health record (EHR) and to exchange clinical data of the patients they assist. The present study aims to review and discuss aspects in connection with the confidentiality and privacy of data in the health records of individuals in this new scenario. To start with, a conceptual framework is defined for the EHR and the HCEN. The current legal approach with regard to this topic is reviewed, emphasizing on general concepts of privacy and addressing specific aspects that have to do with the access and custody of health records. The implementation of the HCEN system initially represents several benefits, both from the healthcare perspective (patient and physician) and from the viewpoint of the national information system for health. In order to implement the HCEN, it was necessary to regulate a few legal aspects, as the rights and obligations arising in the new system.


Atualmente se está implementando no Uruguai, o prontuário eletrônico nacional do paciente (HCEN por seu nome em espanhol), no qual cada prestador de serviços de saúde está obrigado a contar com um prontuário eletrônico do paciente (HCE) e ao intercambio dos dados clínicos das pessoas que atendem. O objetivo deste trabalho é revisar e discutir os aspectos relacionados à confidencialidade e a privacidade dos dados do prontuário eletrônico dos pacientes nestas novas condições. Define-se um marco conceitual relativo à HCE e ao sistema de HCEN. Faz-se uma revisão dos aspectos jurídicos atuais relacionados ao tema, com ênfase nos conceitos gerais da privacidade incluindo aspectos específicos vinculados ao acesso e custodia dos prontuários eletrônicos. A priori a implementação do sistema HCEN apresenta vários benefícios, tanto do ponto de vista assistencial (paciente e médico) como do ponto de vista do sistema nacional de informação em saúde. Para a implementação da HCEN, foi necessário regular alguns aspectos jurídicos como os direitos e as obrigações emergentes do novo sistema.
