RESUMO

Introducción: El desarrollo positivo es un estadio de ajuste psicosocial que acentúa las potencialidades y los recursos entre jóvenes y sus contextos próximos. En Australia, se desarrolló el primer modelo de desarrollo positivo para adultos emergentes, el cual consta de cinco componentes (competencia social, satisfacción con la vida, confianza y tolerancia con los otros, confianza hacia autoridades e instituciones, acción y compromiso cívico), pero no ha sido investigado en Chile. Objetivo: Analizar la evidencia disponible en la literatura científica sobre los cinco componentes del modelo de desarrollo positivo en adultos emergentes universitarios de Chile. Materiales y métodos: Revisión narrativa de la literatura publicada entre 2013 y 2023, en bases de datos Web of Science, Scopus, SciELO, Redalyc y Dialnet. Resultados: Se obtuvieron 83 artículos, de los cuales 53 cumplieron los requisitos de inclusión; en su mayor parte fueron estudios cuantitativos (81,13%) y en español (75,47%). Se evidenció una disparidad en la cantidad de estudios por temática; se encuentra mayor investigación en satisfacción con la vida y acción y compromiso cívico. Conclusiones: Existen brechas en la literatura científica chilena en el estudio del desarrollo positivo; además de que se discuten particularidades idiosincrásicas y desafíos asociados a la etapa de adultez emergente.


Introduction: Positive development is a stage of psychosocial adjustment that accentuates the potentials and resources of young people and their close contexts. The first positive development model for emerging adulthood was developed in Australia, which includes five components: social; life satisfaction; trust and tolerance of others; trust in the authorities and institutions; and action and civic engagement. However, this model has not been investigated in Chile. Objective: To analyze the evidence available in the scientific literature on the five components of the positive development model in emerging adults universities. Materials and methods: A narrative review of the literature published between 2013 and 2023 in the Web of Science, Scopus, SciELO, Redalyc, and Dialnet databases was conducted. Results: 83 articles were selected, of which 53 met the inclusion criteria; most of them were qualitative studies (81.13%) and in Spanish (75.47%). There is an evident disparity in terms of the number of studies and topics, e.g., there is more research on life satisfaction and civic action and commitment. Conclusions: There are gaps in the Chilean scientific literature in the study of positive development. In addition, idiosyncratic particularities and challenges associated with the stages of emerging adulthood are discussed.

RESUMO

INTRODUCTION: Stroke in young individuals is becoming increasingly prevalent worldwide. Its causes can vary widely, so a thorough investigation by a multidisciplinary team is needed. Pinpointing the precise underlying pathology responsible for the stroke yields benefits for patients, particularly in recurrent events. CASE PRESENTATION: A 38-year-old man presented to the emergency department with symptoms suggestive of stroke, including right hemiparesis, dysarthria, ataxic gait, and right central facial palsy. The brain magnetic resonance image revealed an ischemic lesion located in the left basal ganglia and near the corona radiata. Following an extensive workup, a diagnosis of nephrotic was reached. Histopathology and the exclusion of secondary causes confirmed primary membranous nephropathy as the underlying condition. The patient underwent treatment tailored to address the specific glomerulopathy, along with anticoagulation therapy and immunosuppression as per current guidelines. Subsequent assessments showed stabilization of renal function, resolution of the edema, and the absence of new thromboembolic events during follow-up. CONCLUSION: The nephrotic syndrome should be recognized as a potential underlying cause of stroke in young patients and, therefore, it should be included in the differential diagnosis during the evaluation of patients with coagulopathies. Nephrotic syndrome screening may be done by conducting a simple urinalysis readily available in most healthcare facilities. This underlines the importance of considering renal pathology in the assessment of stroke etiologies, especially when coagulation abnormalities are present.


Introducción. Los eventos cerebrovasculares en los jóvenes son un problema creciente en todo el mundo. Su etiología puede ser variada y requieren un trabajo riguroso de un equipo multidisciplinario. La identificación de la enfermedad específica que conduce al ictus tiene un impacto beneficioso en los pacientes, especialmente en aquellos con eventos recurrentes. Presentación del caso. Se presenta el caso de un hombre de 38 años que acudió al servicio de urgencias con hemiparesia derecha, disartria, ataxia y parálisis facial central derecha. La resonancia magnética cerebral reveló una lesión isquémica localizada en los ganglios basales izquierdos, cerca de la corona radiada. Después de un estudio exhaustivo, se estableció el diagnóstico de síndrome nefrótico. No obstante, al analizar las características histopatológicas y descartar otras causas secundarias, el diagnóstico final fue una nefropatía membranosa primaria. El paciente recibió tratamiento específico para su glomerulopatía, anticoagulación e inmunosupresión según las guías vigentes. Durante el seguimiento, se encontró estabilización de la función renal, el edema se resolvió y no se identificó ningún nuevo evento tromboembólico. Conclusión. El síndrome nefrótico debe considerarse entre las posibles causas del ictus en pacientes jóvenes y debería tenerse en cuenta en los estudios de coagulopatías. El tamizaje de esta enfermedad requiere únicamente un uroanálisis, el cual está disponible en la mayoría de los centros de atención de salud.

RESUMO

RESUMO O objetivo deste estudo foi compreender as representações sociais de jovens que vivem com o HIV. Estudo qualitativo, ancorado na Teoria das Representações Sociais, realizado com 16 jovens em acompanhamento ambulatorial. Os dados foram coletados entre maio e outubro de 2022, por meio de entrevista semiestruturada. Para o tratamento dos dados, empregou-se a técnica de análise lexical, operacionalizada com o auxílio do software Iramuteq. A representação fortemente associada ao diagnóstico de HIV está relacionada ao desconhecimento, preconceito e aceitação, apresentando, também, elementos positivos como recomeço. Classes: Diagnóstico positivo para o HIV: o 'eu' de agora; HIV em face do desconhecimento e do estigma; e Relações interpessoais: diálogo, acolhimento e respeito necessários aos jovens. Compreendeu-se que as representações sociais dos jovens com HIV refletem a sua condição na sociedade. Os dados deste estudo mostram que existem formas distintas de vivenciar o HIV, muitas vezes representadas pela fragilidade, pela resignação, e outras, pelo fortalecimento. A fim de minimizar a vulnerabilidade do jovem à exposição ao HIV e aos riscos de conviver com o estigma e preconceito social, fazem-se necessárias a adoção de estratégias de conscientização da sociedade sobre a doença e a ampliação da divulgação de políticas públicas que abarcam essa temática.


ABSTRACT This study was aimed at understanding the social representations of young people living with HIV. This is a qualitative study, based on the Social Representations Theory, carried out with 16 young people in outpatient follow-up. Data were collected between May and October 2022, through semi-structured interviews. For data processing, the lexical analysis technique was used, operationalized with the aid of the IRAMUTEQ software. The representation strongly associated with the diagnosis of HIV is related to lack of knowledge, prejudice and acceptance, also presenting positive elements such as a new beginning. Classes: Positive diagnosis for HIV: the new 'me'; HIV in the face of ignorance and stigma; and Interpersonal relationships: dialogue, acceptance and respect necessary for young people. It was understood that the social representations of young people with HIV reflect their condition in society. The data show that there are different ways of experiencing HIV, often represented by fragility, resignation, and other times by strengthening. In order to minimize the vulnerability of young people to exposure to HIV and the risks of living with stigma and social prejudice, it is necessary to adopt strategies to raise awareness about the disease and to expand the dissemination of public policies that cover this topic.

RESUMO

Objective: To describe temporal and spatial patterns and identify the factors associated with the incidence of HIV/AIDS among young people in Brazil. Method: Ecological study of young Brazilians aged 15-24 years with reported HIV/AIDS, from 2001 to 2021. The Joinpoint method was used for the temporal analysis. Spatial clusters were detected using Bayesian methods, spatial autocorrelation, Getis-Ord Gi*, and scan techniques. Four non-spatial and spatial regression models were used to identify factors associated with the result. All statistical analyses considered p < 0.05. Results: In Brazil, the average incidence was 12.29 per 100 000 inhabitants, with an annual increase of 7.3% in the period 2007-2014 and a subsequent 3.4% decrease in 2014-2021. A high-high pattern and hotspots were observed, mainly in municipalities in the South, Southeast, Central-West, and North regions. The primary cluster was located in 572 municipalities in Rio Grande do Sul and Santa Catarina, with the highest relative risks in Manaus (Amazonas) and Rondonópolis (Mato Grosso). The illiteracy rate (ß = -0.08), GINI Index (ß = -3.74) and Family Health Strategy coverage (ß = -0.70) were negatively associated with the result. In contrast, the Firjan Municipal Development Index (ß = 2.37), Social Vulnerability Index (ß = 6.30), percentage of Bolsa Família recipients (ß = 0.04), and per capita income (ß = 0.008) showed a positive association. Conclusion: There was an upward trend in the incidence of HIV/AIDS until 2014, followed by a decline until 2021. High-rate clusters were concentrated in municipalities in the North, South, Southeast and Central-West regions in particular. Indicators of socioeconomic vulnerability had positive or negative effects on the result, depending on the territory investigated.


Objetivo: Describir el patrón temporal y espacial, y determinar los factores asociados a la incidencia de infección por el VIH/sida en jóvenes en Brasil. Método: Estudio ecológico en jóvenes brasileños de 15 a 24 años con diagnóstico de infección por el VIH/sida en el período 2001-2021. Para el análisis temporal se utilizó el método de regresión de puntos de inflexión (joinpoint). Los conglomerados espaciales se detectaron con métodos Bayesianos y de autocorrelación espacial, Gi* de Getis-Ord y escaneo. Se utilizaron cuatro modelos de regresión espacial y no espacial para detectar los factores asociados al resultado. En todos los análisis estadísticos se estableció un valor de p < 0,05 como umbral de significación. Resultados: En Brasil, la incidencia media fue de 12,29 por 100 000 habitantes, con un aumento del 7,3% anual en el período 2007-2014 y una reducción posterior del 3,4% en el período 2014-2021. Se observó un patrón alto/alto y la presencia de puntos calientes, principalmente en municipios del Sur, Sudeste, Centro-Oeste y Norte. El principal conglomerado se localizó en 572 municipios de Rio Grande do Sul y Santa Catarina, y los riesgos relativos más altos se observaron en Manaus (Amazonas) y Rondonópolis (Mato Grosso). La tasa de analfabetismo (ß = -0,08), el índice de Gini (ß = -3,74) y la cobertura de la estrategia de salud familiar (ß = -0,70) mostraron una asociación negativa con el resultado. En cambio, el índice de Firjan de desarrollo municipal (ß = 2,37), el índice de vulnerabilidad social (ß = 6,30), el porcentaje de personas que reciben ayuda del programa de bienestar social Bolsa Família (ß = 0,04) y los ingresos per cápita (ß = 0,008) mostraron una asociación positiva. Conclusión: Hubo una tendencia al aumento de la incidencia de infección por el VIH/sida hasta el 2014, con una reducción posterior hasta el 2021. Los conglomerados de tasas elevadas se concentraron especialmente en los municipios de las regiones Norte, Sur, Sudeste y Centro-Oeste. Los indicadores de vulnerabilidad socioeconómica tienen una influencia positiva o negativa en el resultado, según el territorio investigado.

RESUMO

PURPOSE: The purpose of this study is to summarize the ICF foci, looking beyond body structures and function, and to analyze who has been assessed in research about adolescents and young adults (AYAs) with CP in the phase of transition to adulthood. METHOD: Medline, EMBASE, PsycINFO, and CINAHL databases were searched using terms related to cerebral palsy, adolescents/young adults, health development, participation, and independence. Studies including youth with CP (13-30 years old) published in English from 2014 to 2021 were considered. The methods of assessment reported in the included studies were used to identify the ICF foci and who was assessed. RESULTS: In this study, 86 studies were reviewed. The main ICF foci are activity and participation (51% of the studies), personal factors (23%), ICF not covered (14%), ICF not defined (9%), with environmental factors being the least focused ICF component (3%). Most studies assessed AYAs directly (49% of studies). CONCLUSIONS: Activity- and participation-related constructs are the leading research focus of studies, and more attention is needed concerning environmental factors. AYAs are the main source of information, and the perspectives of other key figures are also being valued. To bridge the gap between child and adult health care, a broader view of health development and approaches to explore AYA developmental issues must be taken.

RESUMO

Background: Overweight and obesity, high blood pressure, hyperglycemia, hyperlipidemia, and insulin resistance (IR) are strongly associated with non-communicable diseases (NCDs), including type 2 diabetes, cardiovascular disease, stroke, and cancer. Different surrogate indices of IR are derived and validated with the euglycemic-hyperinsulinemic clamp (EHC) test. Thus, using a computational approach to predict IR with Matsuda index as reference, this study aimed to determine the optimal cutoff value and diagnosis accuracy for surrogate indices in non-diabetic young adult men. Methods: A cross-sectional descriptive study was carried out with 93 young men (ages 18-31). Serum levels of glucose and insulin were analyzed in the fasting state and during an oral glucose tolerance test (OGTT). Additionally, clinical, biochemical, hormonal, and anthropometric characteristics and body composition (DEXA) were determined. The computational approach to evaluate the IR diagnostic accuracy and cutoff value using difference parameters was examined, as well as other statistical tools to make the output robust. Results: The highest sensitivity and specificity at the optimal cutoff value, respectively, were established for the Homeostasis model assessment of insulin resistance index (HOMA-IR) (0.91; 0.98; 3.40), the Quantitative insulin sensitivity check index (QUICKI) (0.98; 0.96; 0.33), the triglyceride-glucose (TyG)-waist circumference index (TyG-WC) (1.00; 1.00; 427.77), the TyG-body mass index (TyG-BMI) (1.00; 1.00; 132.44), TyG-waist-to-height ratio (TyG-WHtR) (0.98; 1.00; 2.48), waist-to-height ratio (WHtR) (1.00; 1.00; 0.53), waist circumference (WC) (1.00; 1.00; 92.63), body mass index (BMI) (1.00; 1.00; 28.69), total body fat percentage (TFM) (%) (1.00; 1.00; 31.07), android fat (AF) (%) (1.00; 0.98; 40.33), lipid accumulation product (LAP) (0.84; 1.00; 45.49), leptin (0.91; 1.00; 16.08), leptin/adiponectin ratio (LAR) (0.84; 1.00; 1.17), and fasting insulin (0.91; 0.98; 16.01). Conclusions: The computational approach was used to determine the diagnosis accuracy and the optimal cutoff value for IR to be used in preventive healthcare.

RESUMO

Antecedentes existe una relación entre el uso de Instagram y diferentes influencias e interacciones con el bienestar y salud mental de este grupo etario. Objetivo Reconstruir las representaciones sociales acerca de la red social Instagram de adultos emergentes con diferentes niveles de bienestar psicológico y autoestima corporal. Método redes semánticas naturales y entrevistas semiestructuradas fueron aplicadas a N=12 adultos emergentes (19 - 27 años) divididos en dos grupos según sus niveles de autoestima corporal y bienestar psicológico. El análisis de datos estuvo basado en análisis de redes semánticas naturales y algunos procedimientos de codificación teórica. Resultados se muestra la presencia del concepto de "acoso" como núcleo central de la representación social de Instagram en el grupo con baja autoestima corporal y bajo bienestar psicológico, a diferencia del grupo con alta autoestima corporal y alto bienestar psicológico en donde el núcleo central fue "red social". Conclusiones en los grupos estudiados, se encontraron dos representaciones sociales diferentes respecto de Instagram. Estos resultados pueden ser relevantes para aportar a llenar el vacío de conocimiento sobre los significados subjetivos colectivos de los adultos emergentes, teniendo implicancias en la mejor comprensión de las diversas formas de relación que establecen con esta y otras redes sociales.


Background There is a relationship between the use of Instagram and various influences and interactions with the well-being and mental health of this age group. Objective To reconstruct the social representations of the Instagram social network among emerging adults with different levels of psychological well-being and body esteem. Method Natural semantic networks and semi-structured interviews were conducted with N=12 emerging adults (19 - 27 years old) divided into two groups based on their body self-esteem and psychological well-being levels. Data analysis relied on natural semantic network analysis and theoretical coding. Results The concept of "harassment" is revealed as the central core of the social representation of Instagram in the group with low body self-esteem and low psychological well-being, unlike the group with high body esteem and high psychological well-being where the central core was the "social network" itself. Conclusions Two different social representations of Instagram were found in the studied groups. These results could contribute to filling the knowledge gap about the collective subjective meanings of emerging adults, impacting the better understanding of the diverse relationships they establish with this and other social networks.

RESUMO

Objetivo. Determinar la presencia y dirección de la relación entre alfa-amilasa salival (AAs), edad, sexo e índice de masa corporal (IMC) en adultos jóvenes. Métodos. Este estudio transversal se desarrolló con una muestra de 50 estudiantes de odontología de 19 a 34 años de edad, 58% mujeres y 42% hombres. Se recogieron muestras de saliva entera sin estimular en la mañana (6:30-7:30 a.m.) y en la tarde (4:00-6:00 p.m.). Los valores de AAs se determinaron mediante método cinético y se expresaron como media ± desviación estándar. Se realizaron análisis descriptivo de datos, prueba de chi-cuadrado, prueba de correlación de Pearson y prueba t de muestras pareadas. Resultados. El IMC promedio fue de 23,85 ± 3,30 kg/m2, 66% de los participantes presentó peso normal (IMC ≤ 25 kg/m2). Los niveles de AAs por la tarde (282,74 ± 59,60 U/ml) fueron mayores a los de la mañana (190,84 ± 61,80 U/ml), (t = 16,51, p < 0,0001). Los hombres mostraron niveles de AAs más altos que las mujeres (p < 0,0001). La edad no mostró asociación con los niveles de AAs. Los valores de IMC y AAs presentaron una correlación positiva (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusión. El nivel de actividad de AAs se puede utilizar como posible biomarcador para evaluar el IMC en relación con el sexo, especialmente en los adultos jóvenes.


Objective. To determine the presence and direction of the relationship between salivary alpha-amylase (sAA), age, sex, and body mass index (BMI) in young adults. Methods. This cross-sectional study was developed with a sample of 50 dental students from 19 to 34 years of age, 58% women and 42% men. Unstimulated whole saliva samples were collected in the morning (6:30-7:30 a.m.) and in the afternoon (4:00-6:00 p.m.). sAA values were determined by the kinetic method and expressed as mean ± standard deviation. Descriptive data analysis, chi-square test, Pearson correlation test, and paired samples t-test were made. Results. Mean BMI was 23.85 ± 3.30 kg/m2, 66% of the participants presented normal weight (BMI ≤ 25 kg/m2). Levels of sAA in the afternoon (282.74 ± 59.60 U/ml) were higher than those in the morning (190.84 ± 61.80 U/ml), (t = 16.51, p < 0, 0001). Men showed higher levels of sAA than women (p < 0.0001). Age did not show an association with sAA levels. BMI and AAs values presented a positive correlation (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusions. AAs activity level can be used as a potential biomarker to assess BMI in relation to sex, especially in young adults.

RESUMO

Resumo Neoplasias cardíacas são raras, tendo como principal representante o mixoma atrial (MA), que corresponde a cerca de metade de todos os casos. O MA tem incidência estimada entre 0.001% e 0.3% na população em geral, no entanto apenas aproximadamente 0,06% desses cursam com eventos embólicos coronarianos. Homem de 33 anos, tabagista, admitido com quadro de precordialgia intensa e irradiação para membro superior esquerdo com duração de uma hora. O eletrocardiograma evidenciou elevação de segmento ST nas derivações D2, D3 e aVF troponina sérica elevada, confirmando infarto com supra desnivelamento do segmento ST (IAMCSST). Foi realizada cineangiocoronariografia, a qual revelou oclusão em terço proximal de artéria coronária direita por trombo. Realizada tentativa de aspiração do trombo, sem sucesso, seguido por angioplastia primária com balão sem colocação de stent. Durante a investigação do quadro, paciente realizou ecocardiograma transtorácico o qual demonstrou massa homogênea de superfície regular, de 5.2 cm x 2.3 cm, aderida ao septo interatrial, com lobulações de características emboligênicas prolapsando para valva mitral e ventrículo esquerdo na diástole, compatível com MA. Foi realizada ressecção cirúrgica com paciente evoluindo assintomático, recebendo alta para seguimento ambulatorial. O caso relatado difere em idade e sexo do perfil epidemiológico típico sendo um dos poucos descritos com acometimento da parede inferior apresentando a artéria coronária direita como culpada. Este relato ratifica a importância do diagnóstico diferencial frente às apresentações de IAMCSST em jovens.


Abstract Cardiac tumors are rare entities, among which atrial myxoma (AM) stands as the most frequent, accounting for approximately half of all reported cases. The incidence of AM is estimated to range from 0.001% to 0.3% within the general population, yet only about 0.06% of these cases present with coronary embolic events. We report on a 33-year-old male smoker who experienced acute, severe precordial pain radiating to the left upper limb, lasting for one hour. The electrocardiographic evaluation demonstrated ST-segment elevation in leads D2, D3, and aVF, alongside significantly elevated serum troponin levels, confirming a diagnosis of ST-segment elevation myocardial infarction (STEMI). Subsequent coronary angiography revealed proximal occlusion of the right coronary artery due to thrombus. An initial attempt of thrombus aspiration was unsuccessful, followed by primary angioplasty with balloon inflation without stent placement. Further diagnostic exploration through transthoracic echocardiography identified a homogenous, smooth-surfaced mass measuring 5.2 cm x 2.3 cm attached to the interatrial septum. This mass, characterized by lobulations, prolapsed into the mitral valve and left ventricle during diastole, consistent with AM. Surgical resection of the mass was successfully performed, with the patient being discharged asymptomatic. In the reported case, the patient's profile, notably his age, and gender, diverges from the typical epidemiological characteristics associated with AM. This case adds to the limited number of reports where the inferior wall is affected by the right coronary artery being occluded. This report emphasizes the significance of differential diagnoses in younger patients presenting with STEMI.
