Alert for the high prevalence of vitamin D deficiency in adolescents in a large Brazilian sample

Abstract Objective: To estimate the prevalence of vitamin D deficiency and severe deficiency in children and adolescents, in a large Brazilian sample. Methodology: Results of 413,988 25(OH)D measurements in children and adolescents aged 0 to 18 years collected between 01/2014 and 10/2018 were obtained from the database of a Clinical Laboratory. In this population, 25 hydroxyvitamin D concentrations below 20 ng/mL are considered deficient, and below 12 ng/mL as severe deficiency. All measurements were performed by immunoassay and the results were distributed by gender, age group, seasonality, and latitude. Results: The mean of 25(OH)D levels was 29.2 ng/mL with a standard deviation of 9.2 ng/mL. Of the total samples, 0.8% had a concentration < 12 ng/mL, and 12.5% of the samples had a concentration < 20 ng/mL, with a higher prevalence in females. Children under 2 years of age had the lowest prevalence. The effects of latitude and seasonality were quite evident. In samples of female adolescents from the southern region in winter, 36% of vitamin D deficiency and 5% of severe deficiency were found. Conclusion: In this large number of measurements of 25(OH)D in children and adolescents, 12.5% had a deficiency and 0.8% had severe deficiency. A greater deficiency was observed among adolescents, especially females, which raises questions about the need for supplementation during this period of life.

Profiles of suicide attempted in children and adolescents

Abstract Objective: Suicide attempt (SA) is the strongest predictive variable for completed suicide. The Department of Cauca in Colombia has an SA rate higher than the national average, but the factors are unknown. The objective was to identify the profiles of SA in children and adolescents of Cauca. Methods: Cross-sectional study, which included all SA (Event-356) records from the SIVIGILA platform in children under 18 years of age between 2016 and 2019. The authors described the variables and multiple correspondence analysis (MCA) with the Burt method, according to the completeness of the data to establish the possible SA profiles using STATA 15.1, and R. The Ethics Committee at Universidad del Cauca approved it. Results: The study found 977 SA during this period, 72.4% female, 97.1% adolescent, 74.4% mestizo, 19.3% indigenous, 45.3% resided in municipalities exposed to the armed conflict, 32.3% expressed ideation and previous attempts, and 15.5% prior attempts. The MCA included 810 SA and identified three profiles: "Classic", which had mestizo adolescents with a history of prior SA, mental illness, or psychoactive substance use problems; "Related to the armed conflict", which included female adolescents with a first SA and residents in municipalities exposed to the armed conflict; "Ethnic" represented by male indigenous, with housing in a rural area. Conclusion: The SA profiles found in Cauca were "Classic", "Related to the armed conflict", and "Ethnic"; these can be considered to implement prevention strategies from a cross-cultural, mental health, and gender perspective, with the presence of the state in the territories.

Endometritis por Actinomyces en una adolescente: a propósito de un caso / Actinomyces endometritis in an adolescent girl: a case report

La actinomicosis pélvica es una infección poco común del tracto genital inferior y la pelvis. La especie causal más frecuente es la bacteria Actinomyces israelii, y se debe sospechar en toda paciente que presente dolor crónico pélvico y hemorragia uterina. Aunque se manifiesta excepcionalmente en mujeres sin antecedentes de portar dispositivos intrauterinos, es importante considerarla como diagnóstico. Se presenta el caso clínico de una paciente de 12 años con hemorragia uterina anormal resistente al tratamiento, que requirió intervención quirúrgica, incluyendo biopsia endometrial. El diagnóstico resultante fue actinomicosis endometrial. Este caso aporta la actualización del conocimiento sobre esta rara enfermedad y su presentación poco frecuente en adolescentes(AU)

Pelvic actinomycosis is a rare infection of the lower genital tract and pelvis. The most common causative species is the bacterium Actinomyces israelii, and it should be suspected in any patient who presents with chronic pelvic pain and uterine bleeding. Although it occurs exceptionally in women without a history of carrying intrauterine devices, it is important to consider it as a diagnosis. It is presented the clinical case of a 12-year-old patient with abnormal uterine bleeding resistant to treatment, which required surgical intervention, including endometrial biopsy. The resulting diagnosis was endometrial actinomycosis. This case contributes to updating knowledge about this rare disease and its uncommon presentation in adolescents(AU)

Examining the Impact of Acute Binge Alcohol Consumption on Trabecular Morphometry and Tensile Strength in Adolescent Sprague Dawley Rat Mandibles / Análisis del Impacto del Consumo Excesivo de Alcohol en la Morfometría Trabecular y la Resistencia a la Tracción en Mandíbulas de Ratas Adolescentes Sprague Dawley

SUMMARY: Underage drinking has become a major public concern having a negative impact on the growth and development of the skeleton. Peak bone mass is attained during adolescence hence the aim of the study was to investigate the effect of acute binge alcohol consumption on trabecular morphometry and tensile strength of the adolescent mandible in the Sprague Dawley (SD) rat. The study comprised of 24 SD rats, aged 7 weeks, placed into either the alcohol-exposed [n=12 (6 males and 6 female)] or pair-fed control group [n=12 (6 male and 6 female)]. The treatment of the groups was as follows; the alcohol exposed group and the pair-fed control were administered a single daily dose of 3 g/kg of 20 % alcohol 3 days a week (alternate days) for 7 days and a caloric equivalent dose of maltose dextrin via oral gavage, respectively. The animals were terminated on day 7 via pentobarbital injection. The mandibles were harvested and scanned using a Nikon XTH 255L 3D-microCT scanner (Nikon Metrology, Leuven, Belgium), and biomechanical tests were done using a Shimadzu universal tensile strength testing machine (China). Following scanning and reconstruction, the trabecular morphometry was assessed using Volume Graphics Studio® software. A 3-point bending test was used to evaluate the tensile strength of the bone. Findings from our study showed changes in some trabecular parameters in the female alcohol-exposed group, while the male groups remained unaffected. No changes in tensile strength were seen when comparing male pair-fed control and alcohol-exposed groups and when comparing female pair-fed control and alcohol-exposed groups. Trabecular and tensile strength differences were observed between the sexes when comparing male pair-fed control and alcohol-exposed groups to female pair-fed control and alcohol-exposed groups. These findings do suggest that acute binge alcohol consumption has detrimental effects on the bone micro-architecture in female alcohol-exposed rats and that differences are seen between the sexes.

El consumo de alcohol entre menores de edad se ha convertido en una importante preocupación pública que tiene un impacto negativo en el crecimiento y desarrollo del esqueleto. La masa ósea máxima se alcanza durante la adolescencia, por lo que el objetivo del estudio fue investigar el efecto del consumo excesivo de alcohol en forma aguda sobre la morfometría trabecular y la resistencia a la tracción de la mandíbula en ratas adolescente Sprague Dawley (SD). El estudio estuvo compuesto por 24 ratas, de 7 semanas de edad, colocadas en el grupo control expuesto al alcohol [n=12 (6 machos y 6 hembras)] y alimentado en parejas [n=12 (6 machos y 6 hembras)]. El tratamiento de los grupos fue el siguiente; al grupo expuesto al alcohol y al control alimentado en parejas se les administró una dosis única diaria de 3 g/kg de alcohol al 20 % 3 días a la semana (días alternos) durante 7 días y una dosis equivalente calórica de maltosa dextrina mediante sonda oral, respectivamente. Los animales fueron sacrificados el día 7 mediante inyección de pentobarbital. Las mandíbulas se recolectaron y se escanearon utilizando un escáner 3D-microCT Nikon XTH 255L (Nikon Metrology, Lovaina, Bélgica), y las pruebas biomecánicas se realizaron utilizando una máquina de prueba de resistencia a la tracción universal Shimadzu (China). Después del escaneo y la reconstrucción, la morfometría trabecular se evaluó utilizando el software Volume Graphics Studio®. Se utilizó una prueba de flexión de 3 puntos para evaluar la resistencia a la tracción del hueso. Los hallazgos de nuestro estudio mostraron cambios en algunos parámetros trabeculares en el grupo de hembras expuestas al alcohol, mientras que los grupos de machos no se vieron afectados. No se observaron cambios en la resistencia a la tracción al comparar los grupos control de machos alimentados en parejas y los grupos expuestos al alcohol y al comparar los grupos control de las hembras alimentadas en parejas y los grupos expuestos al alcohol. Se observaron diferencias trabeculares y de resistencia a la tracción entre los sexos al comparar los grupos control de los machos alimentados en parejas y expuestos al alcohol con los grupos de control de hembras alimentadas en parejas y expuestas al alcohol. Estos hallazgos sugieren que el consumo excesivo de alcohol tiene efectos perjudiciales sobre la microarquitectura ósea en ratas hembras expuestas al alcohol y que se observan diferencias entre los sexos.

The principal emerging themes included family dynamics, school environment connection, challenges in treatment adherence, age at the time of diagnosis disclosure, and time elapsed since then. Analyzing these young people's narratives allowed us to explore individual and social aspects of their experiences, revealing their similarities and differences. The circle dance workshops provided a playful space for expressing emotions and feelings through body movements, expanding young people's perspectives on the future.

"Revelando", no gerúndio: segredo e estigma nas práticas de cuidado às crianças e adolescentes vivendo com HIV/Aids / "Revealing in the gerund": secrecy and stigma in practices of care for children and adolescents living with HIV/Aids

Resumo O artigo analisa as práticas de cuidado e o processo de revelação do diagnóstico a crianças e adolescentes vivendo com HIV/Aids. Foi realizado um estudo de caso em um ambulatório localizado em um hospital público do Rio de Janeiro (RJ), através de observação participante, entrevistas semiestruturadas com profissionais de saúde e consulta a documentos produzidos pelos profissionais. A análise, baseada na sociologia de Simmel e Goffman, aponta a revelação do diagnóstico como uma marca que acompanha todo o cuidado estabelecido com os usuários e dá luz a questões como o segredo, o estigma e as possíveis compreensões acerca da condição de saúde estabelecidas. Com isso, as relações institucionalizadas contribuem para um progressivo contato com a condição de portador de um estigma e fazem existir fases de uma carreira de doente protegido pela informação.

Abstract This article analyzes practices of care and the HIV diagnosis disclosure process to children and adolescents living with HIV/AIDS. A case study was conducted in an outpatient clinic located in a public hospital in Rio de Janeiro through participant observation, semi-structured interviews with health professionals, and the consultation of documents produced by the professionals. The analysis, based on the sociology of Simmel and Goffman, points to the revelation of the diagnosis as a hallmark that accompanies all the care established with users and sheds light on issues such as secrecy, stigma and the possible understandings about the health condition established. As a result, institutionalized relationships contribute to a progressive contact with the condition of bearing a stigma and enable phases of a patient's life protected by information to exist.

Manejo Ortodóncico Quirúrgico de la Displasia Cleidocraneal en Pacientes en Crecimiento

El objetivo de este estudio fue describir las alternativas terapéuticas ortodóncico-quirúrgicas más utilizadas en la actualidad para el manejo de la displasia cleidocraneal en pacientes en crecimiento. Se realizó una búsqueda de literatura durante mayo de 2023 en las bases de datos Pubmed, Epitemonikos, Dentistry & Oral Sciences Source y LILACS sobre reporte de casos que presentaran estrategias de tratamiento ortodóncico-quirúrgico en pacientes menores de 18 años con displasia cleidocraneal. Seis artículos cumplieron con los criterios de inclusión. De ellos se obtuvieron siete reportes de casos. Las edades de los pacientes fluctúan entre los 10 y 16 años. Las estrategias de tratamiento consisten en al menos dos etapas de tratamiento ortodóncico quirúrgicas que involucran la extracción de dientes primarios y supernumerarios y la exposición quirúrgica de dientes permanentes retenidos para permitir su erupción y/o su tracción ortodóncica. Algunos casos son finalizados con cirugía Ortognática (Osteotomía Le Fort I de avance maxilar). La extracción de dientes primarios y supernumerarios, fenestración y tracción ortodóncica de los dientes permanentes retenidos y la cirugía ortognática al finalizar el crecimiento (cuando sea necesario) se propone actualmente como la mejor alternativa terapéutica para el tratamiento de pacientes con displasia cleidocraneal.

The objective of this study was to describe the orthodontic-surgical therapeutic alternatives most used nowadays, for the management of CCD in growing patients. A literature search for case reports was carried out through May, 2023 in PubMed, Epitemonikos, Dentistry & Oral Sciences Source and LILACS databases. We included case reports that presented complete orthodontic-surgical treatment strategies in patients with DCC under 18 years of age. Six articles met the inclusion criteria and seven case reports were identified. The age of cases ranged from 10 to 16 years. Treatment strategies consisted of at least two stages of surgical orthodontic treatment involving extraction of primary and supernumerary teeth and surgical exposure of impacted permanent teeth to allow spontaneous eruption or orthodontic traction. Some cases were completed with orthognathic surgery. Extraction of primary and supernumerary teeth, fenestration and orthodontic traction of retained permanent teeth and orthognathic surgery at the end of growth (when necessary) is currently proposed as the best therapeutic alternative for the treatment of patients with DCC.

Insegurança alimentar e nutricional e os comportamentos de risco e proteção para saúde em adolescentes durante a pandemia de covid-19 / Food and nutritional insecurity and health risk behaviors in adolescents during the COVID-19 pandemic

RESUMO A pandemia de covid-19 reduziu o acesso aos alimentos e aumentou a insegurança alimentar. Objetivouse analisar a prevalência de Insegurança Alimentar e Nutricional (IAN) em adolescentes brasileiros durante a pandemia de covid-19 segundo características sociodemográficas e examinar a associação entre IAN e comportamentos de risco e proteção em adolescentes brasileiros durante esse período. Estudo transversal com dados da 'ConVid Adolescentes - Pesquisa de Comportamentos', realizada entre junho e outubro de 2020, utilizando-se um questionário autoaplicado por meio de celular ou computador. A população foi adolescentes de 12 a 17 anos, totalizando 9.470. Utilizou-se a Razão de Prevalência (RP) e Intervalo de Confiança de 95% (IC95%), por meio da regressão de Poisson com variância robusta. A prevalência de IAN (26,1%) foi mais elevada entre os adolescentes da raça/cor preta e parda e que estudam em escola pública. Os adolescentes que relataram IAN tiveram menor consumo de hortaliças e frutas, menor prática de atividade física e maior uso de cigarros e álcool. A IAN foi mais prevalente em adolescentes com piores condições socioeconômicas, e, adolescentes com IAN apresentaram maior frequência de comportamentos de risco para a saúde evidenciando a importância de políticas públicas intersetoriais para a redução de desigualdades.

ABSTRACT The COVID-19 pandemic has reduced access to food and increased food insecurity. The objectives were to analyse the prevalence of Food and Nutritional Insecurity (FNI) in Brazilian adolescents during the COVID-19 pandemic according to sociodemographic characteristics and to examine the association between FNI and risk and protective behaviours in Brazilian adolescents during the that period. Cross-sectional study with data from the 'ConVid teenagers - Behaviour Survey,' carried out between June and October 2020, using a self-administered questionnaire via mobile phone or computer. The population was made up of teenagers aged 12 to 17, totalling 9,470. The Prevalence Ratio (PR) and 95% Confidence Interval (95% CI) were used, using Poisson regression with robust variance. The prevalence of FNI (26.1%) was higher among adolescents of black and mixed race/colour and who study in public schools. Adolescents who reported FNI had lower consumption of vegetables and fruits, less physical activity, and greater use of cigarettes and alcohol. FNI was more prevalent in adolescents with worse socioeconomic conditions, and adolescents with FNI showed a higher frequency of health risk behaviours, highlighting the importance of intersectoral public policies to reduce inequalities.

Prevalence of depression and anxiety and associated factors among students in southern Brazil: results from Respire study / Prevalência de depressão e ansiedade e fatores associados em estudantes no sul do Brasil: resultados da pesquisa Respire

INTRODUCTION: The prevalence of anxiety and depression symptoms has significantly increased in Brazil since the beginning of the COVID-19 pandemic. However, the studies investigating the prevalence of these symptoms in school-aged in Brazil are scanty. OBJECTIVE: To identify the prevalence of moderate or severe symptoms of depression and anxiety and the associated factors among students in southern Brazil. METHODS: This was a census study with all 14 sites of the Federal Institute Sul-riograndense. We used a self-administered, online instrument to assess biological, sociodemographic, health, nutrition, and behavior-related variables. The Hospital Anxiety and Depression Scale assessed depression and anxiety. RESULTS: The sample consisted of 5,112 students. The prevalence of students who presented moderate or severe symptoms of anxiety and depression was 34.3% and 24.3%, respectively. In the fully adjusted analysis, factors associated with anxiety and depression symptoms were female sex, low income, screen time at work, worse health perception, unhealthy diet, poor sleep quality, smoking, alcohol consumption, and medication use. Early age and students whose family members or friends died from COVID-19 were associated with anxiety. Married and having less screen time during leisure was a protective factor for depression. Physical activity reduced by 18% and 33% the likelihood of moderate or severe symptoms of anxiety and depression, respectively. CONCLUSION: Public policies to improve the health care of Brazilian students during the return to face-to-face activities are required.

INTRODUÇÃO: No Brasil, a prevalência de sintomas de ansiedade e depressão aumentaram significativamente desde o início da pandemia de COVID-19. No entanto, há uma lacuna no número de estudos que investigaram a prevalência destes sintomas em estudantes de idade escolar no Brasil. OBJETIVO: Identificar a prevalência de depressão e ansiedade e seus fatores associados em estudantes no sul do Brasil. MÉTODOS: Foi realizado um censo em todos os 14 campi do Instituto Federal Sul-rio-grandense através de um instrumento on-line, auto preenchido, com variáveis biológicas, sociodemográficas, de saúde, nutricionais e comportamentais. A saúde mental foi coletada através da Hospital Anxiety and Depression Scale. RESULTADOS: Participaram do estudo 5.112 estudantes com prevalência de sintomas moderados ou severos de ansiedade e depressão de 34,3% e 24,3%, respectivamente. Após a análise ajustada, ser mulher, ter renda baixa, maior tempo de tela no trabalho, pior percepção de saúde, maior consumo de alimentos não saudáveis, baixa qualidade de sono, ser fumante, consumir bebidas alcoólicas e usar medicamentos foram fatores de risco para ansiedade e depressão. Foram associadas somente a ansiedade, ser mais jovem e ter tido familiar/amigo morto por COVID-19. Ser casado e ter menor tempo de tela no lazer foi fator protetor para depressão. Praticar atividade física reduziu 18% e 33% a probabilidade de apresentar sintomas mais severos de ansiedade e depressão, respectivamente. CONCLUSÃO: É importante a implementação de políticas de gestão no cuidado da saúde dos estudantes nas escolas durante o retorno as atividades presenciais.

The median age of the population was 12 years (interquartile range: 11­14 years). Urogenital disease before adolescence was detected in 72 boys (5.7%; 95% CI: 4.5­7.2). Urogenital disease was found in 272 adolescents (14.8%; 95% CI: 13.1­16.7); the most common conditions were balanopreputial adhesions in 5.3% (95% CI: 4.2­6.6), varicocele in 2.7% (95% CI: 2­3.7), and phimosis in 1.8% (95% CI: 1.2­2.6). Conclusions. A genital exam allowed to detect that 14.8% of adolescent boys had a urogenital diseaseThe most common conditions were balanopreputial adhesions, varicocele, and phimosis.

Effect of a Dose-Dependent Administration of Binge Alcohol on the Mandible in the Adolescent Sprague Dawley Rat / Efecto de una Administración Dosis-Dependiente de Alcohol en Exceso en la Mandíbula de la Rata Sprague Dawley Adolescente

SUMMARY: Binge drinking in adolescents has a negative effect on the developing skeleton and the attainment of peak bone mass. Our study aimed to examine the effect of binge drinking on the growth and functional integrity of the adolescent Sprague Dawley rat mandible and to determine if a dosage of 1.5 g/kg is sufficient to produce a binge-model of consumption. A total of eight 7-week-old adolescent (male) Sprague Dawley rats were randomly placed into 4 groups with two rats each: 1-week alcohol-exposed rats, 1-week pair- fed control rats, 4-week alcohol-exposed rats and 4-week pair-fed control rats. The alcohol exposed groups were administered a single daily dose via oral gavage of 1.5 g/kg of 20 % alcohol 3 days a week (alternate days) for 7 or 28 days. The pair-fed control groups were administered a caloric equivalent dose of maltose dextrin via oral gavage on the same days as the alcohol-exposed rats. The one-week alcohol exposed, and control rats were terminated on day 7 and the four-week alcohol exposed and control rats on day 28. The mandibles were dissected out and osteometric measurements determined using a digital vernier caliper. Bones were scanned using a 3D-microCT scanner (Nikon XTH 255L). Biomechanical tests were done using a Shimadzu universal testing machine. Differences observed were regarding mandibular osteometry, which showed a reduced height in the central portion of the alveolar bone (Al'-Me), and an increase in the height of the condylar head (Cd-Ag) in the 1-week alcohol-exposed rats when compared to the 1-week pair-fed control rats. No other differences were noted. Lack of significant changes seen between the alcohol and pair-fed control groups in both acute binge and chronic binge exposed rats is likely due to the low dose of alcohol administered to the rats in the study thus a higher dose is proposed.

El consumo excesivo de alcohol en adolescentes tiene un efecto negativo en el desarrollo del esqueleto y en la consecución de la masa ósea máxima. Nuestro estudio tuvo como objetivo examinar el efecto del consumo excesivo de alcohol sobre el crecimiento y la integridad funcional de la mandíbula de la rata adolescente Sprague Dawley y determinar si una dosis de 1,5 g/kg es suficiente para producir un modelo de consumo compulsivo. Un total de ocho ratas Sprague Dawley adolescentes (machos) de 7 semanas de edad se colocaron aleatoriamente en 4 grupos con dos ratas cada uno: ratas expuestas al alcohol durante 1 semana, ratas de control alimentadas en parejas durante 1 semana, ratas expuestas al alcohol durante 4 semanas, y ratas de control alimentadas en parejas durante 4 semanas. A los grupos expuestos al alcohol se les administró una dosis única diaria mediante sonda oral de 1,5 g/kg de alcohol al 20 % 3 días a la semana (días alternos) durante 7 o 28 días. A los grupos de control alimentados por parejas se les administró una dosis calórica equivalente de maltosa dextrina mediante sonda oral los mismos días que a las ratas expuestas al alcohol. Las ratas expuestas al alcohol durante una semana, las ratas de control al día 7, las ratas expuestas al alcohol durante cuatro semanas y las ratas de control al día 28. Se diseccionaron las mandíbulas y se determinaron las mediciones osteométricas utilizando un calibre vernier digital. Los huesos se escanearon utilizando un escáner 3D-microCT (Nikon XTH 255L). Las pruebas biomecánicas se realizaron utilizando una máquina de pruebas universal Shimadzu. Las diferencias observadas se relacionaron con la osteometría mandibular, que mostró una altura reducida en la porción central del hueso alveolar (Al'-Me) y un aumento en la altura de la cabeza condilar (Cd-Ag) en las ratas expuestas al alcohol durante una semana, en comparación con las ratas control alimentadas en parejas durante una semana. No se observaron otras diferencias. La falta de diferencias significativas entre los grupos de alcohol y de control alimentados en parejas expuestas a ebriedad aguda y ebriedad crónica, probablemente se deba a la baja dosis de alcohol administrada a las ratas en el estudio, por lo que se propone una dosis más alta.

Results of the Surgical Approach of Idiopathic Scoliosis in Adolescents and Postoperative Quality of Life: Systematic Literature Review / Resultados da abordagem cirúrgica da escoliose idiopática em adolescentes e qualidade de vida pós-operatória: Revisão sistemática de literatura

Abstract Adolescent idiopathic scoliosis is considered the most severe and common spinal deformity, affecting children and adolescents still in the neuropsychomotor development phase before they reach skeletal maturity. This study aimed to evaluate the surgical approach to adolescent idiopathic scoliosis (AIS), considering the results associated with the reduction of pathological curvature, pulmonary function, and repercussions on the quality of life of adolescents undergoing such treatment. Systematic literature review, with a quantitative and qualitative approach to the data collected, structured according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), carried out in the databases linked to the Medical Literature Analysis and Retrieval System Online (MEDLINE) and Latin American and Caribbean Health Sciences Literature (LILACS). The total sample of the studies was 638 adolescents with AIS, with a mean age of 14.93 years ± 1.24. The mean correction of the main pathological curvature in the studies was 55.06% ± 12.24. In all of the selected studies using posterior spinal fusion to correct AIS, there was a significant reduction in pathological curvatures (> 49%), and the recurrence of curvature in none of the studies exceeded a pathological gain of more than 5%. As for lung function, the studies showed significant increases in forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) in patients with severe AIS, and no pulmonary function losses were reported after surgery to correct AIS.

Resumo A escoliose idiopática do adolescente (EIA) é considerada a deformidade vertebral de maior gravidade e ocorrência, que acomete crianças e adolescentes ainda na fase de desenvolvimento neuropsicomotor, antes de atingirem a maturidade esquelética. Este estudo teve como objetivo avaliar a abordagem cirúrgica da EIA, considerando resultados associados à redução de curvatura patológica, função pulmonar e repercussões na qualidade de vida dos adolescentes submetidos a tal tratamento. Revisão Sistemática de literatura, com abordagem quanti-qualitativa dos dados coletados, cuja estruturação se deu conforme as orientações de Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) realizada nas bases de dados vinculadas à Medical Literature Analysis and Retrieval System Online (MEDLINE) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). A amostra total dos estudos foi de 638 adolescentes com EIA, com uma idade média de 14,93 anos ± 1,24. A correção média da curvatura patológica principal nos estudos foi de 55,06% ± 12,24. Em todos os estudos selecionados com fusão espinhal posterior para correção da EIA verificou-se redução significativa das curvaturas patológicas (> 49%), sendo que a reincidência de curvatura em nenhum dos estudos superou um ganho patológico superior a 5%. Quanto à função pulmonar, os estudos apontaram ganhos significativos de volume expiratório forçado em 1 segundo (VEF1) e capacidade vital forçada (CVF) em pacientes com EIA grave. Além disso, não foram relatados prejuízos de função pulmonar após intervenção cirúrgica para correção da EIA.

Factores asociados al riesgo e intentos suicidas en estudiantes de carreras de la salud: estudio transversal / Factors associated with suicide risk and attempts in healthcare students: A cross-sectional study

Introducción Las muertes por suicidio en jóvenes han ido en aumento en las últimas décadas y se considera un problema de salud pública prioritario a nivel mundial, siendo un evento parcialmente prevenible. La prevalencia de ideas suicidas es alta entre estudiantes universitarios, especialmente en carreras de la salud. El objetivo de este estudio fue medir la prevalencia de alto riesgo suicida en este grupo específico e identificar factores asociados, con la finalidad de aportar evidencia empírica para la construcción de estrategias efectivas de prevención del suicidio. Métodos Se realizó un estudio transversal basado en una encuesta en línea a estudiantes de carreras de la salud, casi al final del primer año de la pandemia de COVID-19, para conocer la frecuencia del riesgo suicida y sus factores asociados. La muestra fue de 477 estudiantes (70,8% mujeres, edad promedio 21,7 ± 2,5 años), de ocho carreras de la salud. Los datos se recogieron en enero de 2021. Resultados Un 22,6% de los jóvenes reportó un alto riesgo suicida en la escala de Okasha y 3,4% hizo un intento suicida en el año previo. Los factores asociados al alto riesgo suicida fueron: tener una orientación no-heterosexual, una trayectoria académica irregular, experiencias de violencia física y/o psicológica, mayores niveles de sintomatología depresiva y ansiosa, así como menores niveles de apoyo social de amigos y de la familia. Conclusiones Las cifras de riesgo e intentos suicidas son elevadas en este grupo de estudiantes y existe un perfil de factores que podrían orientar acciones más efectivas, tales como apoyo a grupos de mayor riesgo y hacer tamizaje para identificar y dar ayuda a jóvenes con alto riesgo suicida y con problemas de salud mental.

Introduction Suicide deaths in young people have been increasing in recent decades and are considered a major public health problem worldwide, being a partially preventable event. The prevalence of suicidal ideation is high among university students, especially in health careers. The objective of this study was to measure the prevalence of high suicidal risk in this specific group and to identify associated factors, aiming to provide empirical evidence for the construction of effective suicide prevention strategies. Methods A cross-sectional study was conducted based on an online survey directed to healthcare students near the end of the first year of the COVID-19 pandemic to learn about the frequency of suicidal risk and its associated factors. The sample consisted of 477 students (70.8% female, mean age 21.7 ± 2.5 years) from eight healthcare majors. The data were collected in January 2021. Results 22.6% of the young people reported a high suicide risk on the Okasha scale, and 3.4% made a suicide attempt in the previous year. Factors associated with high suicidal risk were having a non-heterosexual orientation, an irregular academic trajectory, experiences of physical and/or psychological violence, higher levels of depressive and anxious symptomatology, as well as lower levels of social support from friends and family. Conclusions Suicide risk and attempt levels are high in this group of students, and there is a group of factors that could guide more effective actions, such as support for higher-risk groups and screening to identify and provide support to young people at high suicidal risk and with mental health conditions.

Asociación entre los marcadores lipídicos en la infancia/ adolescencia y los eventos cardiovasculares en la adultez: una revisión sistemática / Association between lipid markers in childhood/ adolescence and cardiovascular events in adulthood: A systematic review

Introducción. La asociación entre los marcadores lipídicos en la infancia/adolescencia y la incidencia de eventos clínicos cardiovasculares en la adultez está poco explorada en la literatura. El objetivo de esta revisión sistemática fue analizar la evidencia disponible sobre este tema. Población y métodos. Esta revisión sistemática se realizó de acuerdo con las guías PRISMA. Se realizó una búsqueda bibliográfica para detectar los estudios que evaluaron la asociación entre los niveles lipídicos en la edad pediátrica y la incidencia de eventos cardiovasculares en la edad adulta. No hubo restricciones idiomáticas ni geográficas en la búsqueda. Resultados. En total, cinco estudios observacionales (todas cohortes prospectivas) que incluyeron 43 540 pacientes fueron identificados y considerados elegibles para este estudio. Cuatro estudios evaluaron el nivel de triglicéridos; todos reportaron una asociación significativa entre este marcador en la edad pediátrica y los eventos cardiovasculares en la adultez. Un estudio reportó la misma asociación con el nivel de colesterol total, mientras que otro evidenció el valor predictivo de la lipoproteína (a) para el mismo desenlace clínico. Un solo estudio evaluó el colesterol asociado a lipoproteínas de alta densidad (C-HDL), sin encontrar una relación con el punto final de interés. El análisis del colesterol asociado a lipoproteínas de baja densidad (C-LDL) arrojó resultados contradictorios, aunque la asociación fue significativa en los estudios con un tamaño muestral más grande y con un mayor número de eventos durante el seguimiento. Conclusión. Los datos de esta revisión sugieren que las alteraciones de los marcadores lipídicos en la infancia y la adolescencia se asocian con un mayor riesgo cardiovascular en la adultez temprana y media.

Introduction. The association between lipid markers in childhood/adolescence and the incidence of clinical cardiovascular events in adulthood has been little explored in the bibliography. The objective of this systematic review was to analyze available evidence on this topic. Population and methods. This systematic review was conducted in accordance with the PRISMA guidelines. A comprehensive bibliographic search was done to find studies assessing the association between lipid levels in childhood and the incidence of cardiovascular events in adulthood. There were no language or geographic restrictions. Results. A total of 5 observational studies (all prospective cohorts) including 43 540 patients were identified and considered eligible for this study. Four studies assessed triglyceride levels; all reported a significant association between this lipid marker in childhood and cardiovascular events in adulthood. A study reported the same association with total cholesterol level, while another showed the predictive value of lipoprotein (a) for the same clinical outcome. Only one study assessed high-density lipoprotein cholesterol (HDL-C), but it did not find an association with the endpoint of interest. The analysis of lowdensity lipoprotein cholesterol (LDL-C) showed contradictory results, although the association was significant in the studies with a larger sample size and a higher number of events during follow-up. Conclusion. According to this review, alterations in lipid markers in childhood and adolescence are associated with a higher cardiovascular risk in early and middle adulthood.

Priapismo y leucemia mieloide crónica en adolescente. Debut poco frecuente. Reporte de caso / Priapism and chronic myeloid leukemia in an adolescent. Rare debut presentation. A case report

El priapismo es una erección dolorosa y persistente acompañada o no de estímulo sexual. Una causa poco frecuente de esta anormalidad es la leucemia mieloide crónica. Se han reportado pocos casos de priapismo como manifestación inicial de una leucemia de este tipo en pacientes adolescentes. A continuación, se informa el caso de un paciente de 16 años de edad que presentó priapismo como manifestación inicial de una leucemia mieloide crónica. Durante su evolución, no se realizó aspiración de los cuerpos cavernosos. Se inició tratamiento hematológico específico y, ante la persistencia del priapismo, fue necesario realizar un shunt de cuerpos cavernosos en dos ocasiones, tratamiento a pesar del cual existen altas probabilidades de secuelas.

Priapism is a painful and persistent erection, with or without sexual stimulation. A rare cause of such abnormality is chronic myeloid leukemia. Few cases of priapism as an initial manifestation of this type of leukemia have been reported in adolescent patients. Here we describe the case of a 16-year-old patient who presented with priapism as the initial manifestation of chronic myeloid leukemia. No cavernosal aspiration was performed. A specific hematological treatment was started and, given the persistence of priapism, the patient required 2 corpora cavernosa shunt procedures; despite this treatment, there is a high probability of sequelae.

Morbidity trend and space-time clusters of COVID-19 occurrence in children and adolescents

Abstract Objective: To analyze the morbidity trend and space-time distribution clusters of confirmed COVID-19 cases in children and adolescents. Method: An ecological study of COVID-19 cases confirmed in the Information System from 2020 to 2022 in the age group from 0 to 19 years old, residents in Mato Grosso municipalities, Brazilian Midwest region. A trend analysis of the monthly morbidity rate of cases/100,000 inhabitants was used, following Prais-Winsten's regression. A space-time distribution of the Bayesian incidence rate per 100,000 inhabitants was performed, in addition to a space-time scan to identify high-risk clusters. Results: Of all 79,592 COVID-19 cases studied, 51.6% were in females and 44.21% in people aged 15-19 years old. The mean monthly rate was 265.87 cases per 100,000 inhabitants, with a stationary trend in the period analyzed (Monthly Percentage Variation [MPV]) = 12.15; CI95%[MPV]: -0.73;26.70). The morbidity rate due to COVID-19 was higher in the female gender (283.14/ 100,000 inhabitants) and in the age group from 15 to 19 years old (485.90/100,000 inhabitants). An increasing trend was observed with a greater monthly time variation of 14.42% (CI95%[MPV]: 1.28;29.28)] among those aged from 10 to 14 years old. The primary cluster, which was also the one with the highest Relative Risk (RR = 5,16, p-value = 0.001), included 19 municipalities located in the North health macro-region. Conclusion: The findings indicated a monthly stationary trend in the study population, an increase in the age group from 10 to 14 years old, and areas at a higher risk for the disease in the North health macro-region of the state.

What causes obesity in children and adolescents?

Abstract Objective To present the different aspects that may be involved in the genesis and maintenance of obesity in children and adolescents. Data source Narrative review of articles published in the PubMed, Scielo, Lilacs, Scopus and Google Scholar databases, using the search terms: overweight, obesity, pre-conception, prenatal, infants, schoolchildren, children, and adolescents. The search was conducted in studies written in Portuguese, English and Spanish, including narrative, integrative or systematic reviews, meta-analyses, cross-sectional, case-control and cohort studies, published between 2003 and 2023. Data synthesis A total of 598 studies were initially screened and 60 of them, which showed the main biopsychosocial aspects related to greater risks of excessive adiposity in the pediatric age, were included in the review. The data were presented taking into account the incidence of risk factors and their consequences in six periods: pre-conception, pre-natal, infant, preschool, school age, and adolescence. Conclusions The causal factors described in the scientific literature that have been shown to be related to obesity in childhood and adolescence are presented.
