Calidad de vida relacionada con la salud y los estados de ánimo en estudiantes de instituciones educativas de Antioquia, Colombia / Quality of life related to the health and mood states of students in educational institutions from Antioquia, Colombia / Qualidade de vida relacionada à saúde e ao humor em estudantes de instituições de ensino em Antioquia, Colômbia

Introducción: La calidad de vida relacionada con la salud (CVRS) y los estados de ánimo son indicadores cruciales del bienestar en adolescentes, pero su relación con estudiantes de Antioquia, Colombia, no ha sido ampliamente estudiada. Objetivo: Determinar la CVRS y los estados de ánimo en escolares de Antioquia-Colombia. Materiales y métodos: Estudio transversal con 1957 escolares de 9 a 20 años. Se aplicaron mediciones de CVRS, ansiedad, depresión, hostilidad y alegría, actividad física, comportamiento sedentario, apoyo social de padres y nivel socioeconómico. Resultados: La calidad de vida alta (CVA) es más elevada en hombres, personas con alegría, estudiantes con apoyo de padres, activos físicamente y personas de nivel socioeconómico alto y medio. AL aumentar un año de edad, disminuye en un 15 % la CVA, y al aumentar la depresión, la ansiedad y el comportamiento sedentario disminuye la CVA. Además, los niveles de depresión y ansiedad son mayores en mujeres, estudiantes mayores, sin apoyo de los padres y personas sedentarias. Conclusiones: La CVRS se asocia con estados de ánimo, actividad física, comportamiento sedentario y apoyo de los padres; mientras que los estados de ánimo se asocian con el sexo, el apoyo de los padres, la CVS y el sedentarismo.

Introduction: Even though health-related quality of life (HRQL) and mood states are key indicators of the well-being of adolescents, their relationship has not been analyzed in students from Antioquia, Colombia. Objective: To determine HRQL and mood states in schoolchildren from Antioquia. Materials and methods: A cross-sectional study was conducted on 1,957 schoolchildren and adolescents aged between 9 and 20 years. Measurements of HRQL, anxiety, depression, hostility and happiness, physical activity, sedentary behavior, parental social support, and socioeconomic status were applied. Results: A high quality of life (HQL) was observed more frequently in male participants, students with parental support, physically active, and those belonging to medium and high socioeconomic status. HQL decreased 15% as their age increased by one year. Also, HQL was reduced when depression, anxiety, and sedentary behavior increased. Furthermore, depression and anxiety levels were higher in women, older students, as well as in those without parental control and with sedentary behavior. Conclusions: HRQL is associated with mood states, physical activity, sedentary behavior, and parental support. In contrast, mood states are related to gender, parental support, HQL, and sedentary lifestyle.

Introdução: A qualidade de vida relacionada à saúde (CVRS) e os estados de humor são indicadores cruciais de bem-estar em adolescentes, mas sua relação com estudantes de Antioquia, Colômbia, não foi amplamente estudada. Objetivo: Determinar a CVRS e os estados de humor em escolares de Antioquia-Colômbia. Materiais e métodos: Estudo transversal com 1.957 escolares de 9 a 20 anos.

Mecánica y energética durante la marcha en cinta caminadora en adultos uruguayos saludables: efecto del IMC y la edad / Mechanics and energy during treadmill walking in healthy uruguayan adults: effect of BMI and age / Mecânica e energia durante a caminhada em esteira em adultos uruguaios saudáveis: efeito do IMC e Idade

La evaluación de la marcha en cinta caminadora puede resultar relevante para la toma de decisiones clínicas. No obstante, factores demográficos como la edad y el IMC pueden alterar la interpretación de los resultados. Nuestro objetivo fue obtener variables espacio- temporales, energéticas y costo de transporte durante la velocidad autoseleccionada en cinta caminadora para una muestra representativa de adultos uruguayos (n=28) y evaluar si diferentes rangos de edades e IMC pueden ser factores a tener en cuenta en pruebas clínicas donde se consideren dichas variables. Participaron 17 hombres y 11 mujeres (39,3 ± 14,8 años, 75,9 ± 12,5 kg, 1,74 ± 0,09 m, IMC 25,2 ± 4,06). Se realizó una reconstrucción 3D del movimiento en forma sincronizada con el consumo energético. Se obtuvieron valores de referencia y luego de agrupar los participantes según su IMC y rango de edad se compararon los datos mediante test de t (p≤0.05). Los resultados revelaron discrepancias significativas en las medidas espacio-temporales y energéticas de los adultos uruguayos al caminar en cinta con respecto a la literatura. La marcha difiere entre adultos jóvenes y de mediana edad en su velocidad autoseleccionada (p=0,03), longitud de zancada (p=0,01), trabajo mecánico externo (<0,001) y recuperación de energía mecánica (0,009), destacando la importancia de considerar la edad en evaluaciones clínicas. El IMC no influyó significativamente en estas variables. Estos hallazgos subrayan la necesidad de ajustar las interpretaciones de las pruebas clínicas de la marcha sobre cinta caminadora en adultos uruguayos de mediana edad (45 a 65 años).

Treadmill gait assessment can be relevant for clinical decision-making. However, demographic factors such as age and BMI may alter result interpretation. Our aim was to obtain spatiotemporal, energetic, and cost of transport variables during self-selected treadmill walking speed for a representative sample of Uruguayan adults (n=28) and to assess if different age ranges and BMI could be factors to consider in clinical tests involving these variables. Seventeen men and eleven women participated (39.3 ± 14.8 years, 75.9 ± 12.5 kg, 1.74 ± 0.09 m, BMI 25.2 ± 4.06). A synchronized 3D motion reconstruction was performed with energy consumption. Reference values were obtained and data were compared using t-tests (p≤0.05), after grouping participants by BMI and age range. Results revealed significant discrepancies in spatiotemporal and energetic measures of Uruguayan adults walking on the treadmill, compared to the literature. Gait differed between young and middle-aged adults in their self-selected speed (p=0.03), stride length (p=0.01), external mechanical work (p<0.001), and mechanical energy recovery (0.009), emphasizing the importance of considering age in clinical evaluations. BMI did not significantly influence these variables. These findings underscore the need to adjust interpretations of treadmill gait clinical tests in middle-aged Uruguayan adults (45 to 65 years).

A avaliação da marcha na esteira pode ser relevante para a tomada de decisões clínicas. No entanto, fatores demográficos como idade e IMC podem alterar a interpretação dos resultados. Nosso objetivo foi obter variáveis espaço-temporais, energéticas e custo de transporte durante a velocidade de caminhada autoselecionada na esteira para uma amostra representativa de adultos uruguaios (n = 28) e avaliar se diferentes faixas etárias e IMC podem ser fatores a serem considerados em testes clínicos que envolvam essas variáveis. Dezessete homens e onze mulheres participaram (39,3 ± 14,8 anos, 75,9 ± 12,5 kg, 1,74 ± 0,09 m, IMC 25,2 ± 4,06). Foi realizada uma reconstrução tridimensional do movimento sincronizada com o consumo de energia. Foram obtidos valores de referência e os dados foram comparados usando testes t (p≤0,05), após agrupar os participantes por IMC e faixa etária. Os resultados revelaram discrepâncias significativas nas medidas espaço-temporais e energéticas dos adultos uruguaios ao caminhar na esteira, em comparação com a literatura. A marcha diferiu entre adultos jovens e de meia-idade em sua velocidade autoselecionada (p=0,03), comprimento da passada (p=0,01), trabalho mecânico externo (<0,001) e recuperação de energia mecânica (0,009), destacando a importância de considerar a idade em avaliações clínicas. O IMC não influenciou significativamente essas variáveis. Esses achados destacam a necessidade de ajustar as interpretações dos testes clínicos de marcha na esteira em adultos uruguaios de meia- idade (45 a 65 anos).

IMP3, CDK4, MDM2 and ß-catenin expression in Enchondroma and Central Chondrosarcoma: Diagnostic and prognostic utility.

INTRODUCTION: The role of IMP3, CDK4, MDM2 and ß-catenin proteins in Enchondroma and Central Chondrosarcoma is not totally understood. The aim of this study is to evaluate the immunoexpression of these proteins, associating histological grade, clinical data and prognosis to these tumors. METHODS: This is a retrospective-analytical study of 32 Enchondroma and 70 Central Chondrosarcoma. RESULTS: IMP3, CDK4, MDM2 and ß-catenin expression was observed in 22.82 %, 13.82 %, 17.17 % and in 8.8 % of cases, respectively. All Enchondromas positive for these immunomarkers were located in short tubular bones. The positivity for these antibodies is directly proportional to Chondrosarcoma's histological grade increase. No difference was found between Enchondroma and Chondrosarcoma, Grade 1 for IMP3, CDK4 and ß-catenin positivity. Significant metastasis outcome was observed for IMP3, CDK4, MDM2 and death for MDM2 expression. CONCLUSION: IMP3, CDK4, MDM2 and ß-catenin expression in Enchondromas of short bones phenotypically characterizes these tumors. Their expression has not proven to be useful either as diagnostic markers of these neoplasms or in distinguishing between Enchondroma and Chondrosarcoma, Grade 1. The significant immunoexpression of IMP3, CDK4 and MDM2 in metastatic Chondrosarcoma and the lower survival in those with positivity for MDM2 suggest a possible association of these proteins with tumor aggressiveness.

Disentangling the influence of reservoir abundance and pathogen shedding on zoonotic spillover of the Leptospira agent in urban informal settlements.

Rats are major reservoirs for pathogenic Leptospira, the bacteria causing leptospirosis, particularly in urban informal settlements. However, the impact of variation in rat abundance and pathogen shedding rates on spillover transmission to humans remains unclear. This study aimed to investigate how spatial variation in reservoir abundance and pathogen pressure affect Leptospira spillover transmission to humans in a Brazilian urban informal settlement. A longitudinal eco-epidemiological study was conducted from 2013 to 2014 to characterize the spatial distribution of rat abundance and Leptospira shedding rates in rats and determine the association with human infection risk in a cohort of 2,206 community residents. Tracking plates and live-trapping were used to measure rat abundance and quantify rat shedding status and load. In parallel, four sequential biannual serosurveys were used to identify human Leptospira infections. To evaluate the role of shedding on human risk, we built three statistical models for: (1) the relative abundance of rats, (2) the shedding rate by individual rats, and (3) human Leptospira infection, in which "total shedding", obtained by multiplying the predictions from those two models, was used as a risk factor. We found that Leptospira shedding was associated with older and sexually mature rats and varied spatially and temporally-higher at valley bottoms and with seasonal rainfall (December to March). The point estimate for "total shedding" by rat populations was positive, i.e., Leptospira infection risk increased with total shedding, but the association was not significant [odds ratio (OR) = 1.1; 95% confidence interval (CI): 0.9, 1.4]. This positive trend was mainly driven by rat abundance, rather than individual rat shedding (OR = 1.8; 95% CI: 0.6, 5.4 vs. OR = 1.0; 95% CI: 0.7, 1.4]. Infection risk was higher in areas with more vegetative land cover (OR = 2.4; 95% CI: 1.2, 4.8), and when floodwater entered the house (OR = 2.4; 95% CI: 1.6, 3.4). Our findings indicate that environmental and hydrological factors play a more significant role in Leptospira spillover than rat associated factors. Furthermore, we developed a novel approach combining several models to elucidate complex links between animal reservoir abundance, pathogen shedding and environmental factors on zoonotic spillover in humans that can be extended to other environmentally transmitted diseases.

Influenza outbreak during the surge of SARS-CoV-2 omicron in a metropolitan area from southern Brazil: genomic surveillance.

Influenza circulation was significantly affected in 2020-21 by the COVID-19 pandemic. During this time, few influenza cases were recorded. However, in the summer of 2021-22, an increase in atypical influenza cases was observed, leading to the resurgence of influenza in the southernmost state of Brazil, Rio Grande do Sul (RS). The present study aimed to identify the circulation of FLUAV, FLUBV and SARS-CoV-2 and characterize the influenza genomes in respiratory samples using high-throughput sequencing technology (HTS). Respiratory samples (n = 694) from patients in RS were selected between July 2021 and August 2022. The samples were typed using reverse transcriptase real-time PCR (RT-qPCR) and showed 32% (223/694) of the samples to be positive for SARS-CoV-2, 7% for FLUAV (H3) (49/694). FLUBV was not detected. RT-qPCR data also resulted in FLUAV and SARS-CoV-2 co-infections in 1.7% (4/223) of samples tested. Whole genome sequencing of FLUAV produced 15 complete genomes of the H3N2 subtype, phylogenetically classified in the 3C.2a1b.2a.2a.3 subclade and revealing the dominance of viruses in the southern region of Brazil. Mutation analysis identified 72 amino acid substitutions in all genes, highlighting ongoing genetic evolution with potential implications for vaccine effectiveness, viral fitness, and pathogenicity. This study underscores limitations in current surveillance systems, advocating for comprehensive data inclusion to enhance understanding of influenza epidemiology in southern Brazil. These findings contribute valuable insights to inform more effective public health responses and underscore the critical need for continuous genomic surveillance.

Prevalence and factors associated with the use of traditional medicine in individuals with hypercholesterolemia, hyperglycaemia, and arterial hypertension in Ecuador: results from a population-based study in two health districts.

BACKGROUND: While traditional medicine (TM) is employed by a significant portion of the global population for managing health issues, clinical guidelines and state recommendations often overlook this practice. The aim of this study was to describe the frequency of use of TM to control 3 metabolic risk factors (MRF): hypertension, hypercholesterolemia, and hyperglycaemia; and the sociodemographic, economic, and clinical characteristics associated with the use of TM. METHODS: Cross-sectional descriptive study that analyses data obtained from a representative population survey in 2 health districts, one urban in the south of Quito and another in a forested rural area with diverse ethnic groups in Esmeraldas, Ecuador. We include 602 individuals with at least one MRF. We calculated the proportion of people reporting the regular use of TM (herbal or traditional remedy) to control their MRF and we assessed potential associations with sociodemographic, economic, and clinical characteristics with a multivariable logistic regression model. RESULTS: In two very different sociocultural contexts in Ecuador we found that use of TM to control MRF was frequent (39.4% in Esmeraldas, 31.1% in Quito), frequently in combination with CM. There is a notable percentage of people, 33.9% in Esmeraldas and 39.0% in Quito, who did not take any treatment for their MRF, and the remainder used CM alone. In both settings, an individual's education lever was significantly associated with TM use. Whereas in Quito individuals with higher education more frequently treated their MRF with TM (aOR 2.04, 95% CI 1.03-3.90), in the rural, hard-to-reach context of Esmeraldas, it was more frequent among people with no formal schooling (aOR: 3.76; 95%CI 1.59-8.88), as well as those of younger age (aOR by year: 0.97; 95% CI 0.95-0.99) and afro ethnicity (aOR: 2.13; 95%CI 1.02-4.45). CONCLUSION: Traditional medicine is used by a significant proportion of the population in Ecuador, highlighting the need for a more accessible and intercultural healthcare approach. The health system should ensure access to the necessary information and resources for the management of their metabolic risk factors.

Factors associated with unsuccessful tuberculosis treatment in Manaus, Amazonas, from 2011 to 2021.

OBJECTIVE: To identify vulnerability factors associated with unsuccessful tuberculosis treatment outcomes between 2011 and 2021 in Manaus, Amazonas. METHOD: Ecological study using tuberculosis case notification data from the Notifiable Diseases Information System, from 2011 to 2021, of residents in Manaus. The variables refer to treatment outcomes and patient vulnerability, according to the theoretical model: individual, programmatic and social. The analysis tested the association between vulnerability and tuberculosis treatment non-success, measured by the occurrence of death, loss to follow-up or treatment default. The Odds Ratio estimate with confidence interval was obtained by logistic regression, according to a hierarchical model. RESULTS: The following factors were more likely to lead to unsuccessful tuberculosis treatment: individual vulnerability (age group 20 to 29 years and over 60 years, indigenous race, HIV+, drug use); programmatic vulnerability (not having an HIV test), social vulnerability (special population). CONCLUSION: Individual vulnerability was more strongly associated with non-success. Intervention is needed to explore the points of greatest individual vulnerability, enabling effective action to prevent unsuccessful tuberculosis treatment.

Epidemiology of acute childhood poisoning in pediatric emergencies in Western Mexico.

INTRODUCTION: The increase in the production of substances to enhance the quality of life, the biodiversity of the different ecosystems in Mexico, and the unique characteristics of pediatric patients, contribute to intoxications within this population. METHOD: Analytical retrospective study of admissions to pediatric emergency care due to poisoning in < 16-year-old (2016 to 2020). Included variables were age, gender, type of toxic substance, exposure characteristics, and the season of the year. Frequencies, percentages, range, average and standard deviation were obteined. In the bivariate análisis, the Chi square test was used. A p-value < 0.05 was considered statistically significant. RESULTS: Over 5 years, there were 459 cases, with a prevalence of 3.16%. No gender predominance was observed. The most common was caused by venomous animals (28.5%), followed by medication ingestion (27.6%). Only 5% of cases were suicide attempts, the rest were accidental (95%). Children up to 5 years old were more commonly by medication ingestion, hydrocarbons, or household products (p = 0.03, p = 0.0001), while the causes in older children were contact with venomous animals and ingestion of stimulants drugs (alcohol, amphetamines, cannabis, cocaine) (p = 0.0001, p = 0.006). Intoxication with quaternary ammonium herbicides was lethal in all cases. CONCLUSIONS: Children under the age of 5 are more susceptible to intoxication from common household products. Older kids tend to be more frequently a combination of stimulants drugs.

INTRODUCCIÓN: El aumento en la producción de sustancias para mejorar la calidad de vida, la biodiversidad de los diferentes ecosistemas en México, así como las características propias de los pacientes pediátricos, contribuyen a la intoxicación dentro de esta población. MÉTODO: Estudio retrospectivo analítico de los ingresos por envenenamiento en niños menores de 16 años en urgencias pediátricas (2016 a 2020). Se analizaron la edad, el sexo, el tipo de xenobiótico, las características de exposición y la estación del año. Se obtuvieron frecuencias, porcentajes, rango, promedio y desviación estándar. En el análisis bivariado se utilizó la prueba chi al cuadrado, considerando estadísticamente significativo un valor p < 0.05. RESULTADOS: En el periodo de 5 años se atendieron 459 casos, con una prevalencia del 3.16%. No se observó predominio de sexo. La intoxicación más frecuente fue por animales venenosos (28.5%), seguida de la ingesta de medicamentos (27.6%). El 95% de los casos fueron accidentales y el 5% por intento de suicidio. En los menores de 5 años, lo más frecuente fue la ingesta de medicamentos, hidrocarburos o productos de uso doméstico (p = 0.03, p = 0.0001), mientras que en los mayores de 6 años fue por contacto con animales venenosos e ingesta de drogas estimulantes (alcohol, anfetaminas, cannabis, cocaína) (p = 0.0001, p = 0.006). El 100% de los intoxicados por herbicida cuaternario de amonio fallecieron. CONCLUSIONES: Los menores de 5 años son más propensos a la intoxicación con productos que se utilizan en sus propios domicilios. En los mayores de 6 años es más frecuente la combinación de drogas estimulantes.

Exploring atypical manifestations and multisystem involvement of Epstein-Barr virus infection in hospitalized pediatric patients from Mexico: insights from a tertiary hospital (2012-2022).

INTRODUCTION: Epstein-Barr virus (EBV) infection, with a global prevalence exceeding 95%, typically manifests in children as infectious mononucleosis. However, clinical practice frequently encounters diverse atypical presentations characterized by multisystem involvement, often resulting in an unfavorable clinical course. Our objective is to describe the clinical manifestations and results of EBV infection in a tertiary pediatric hospital in Mexico. METHOD: An observational, transversal, retrospective, and descriptive study that included a systematic review of medical records (2012-2022) of patients under 18 years of age with detectable EBV particles in peripheral blood. RESULTS: The study included 26 patients with a median age of 5 years and a male predominance of 53.8%. Predominant symptoms were fever (85%) and lymphadenopathy (35%). Sixty-five percent had severe and atypical manifestations, including pneumonia and hepatic, hematologic-oncologic, and autoimmune diseases. Anemia, thrombocytopenia and leukopenia were common, with lymphocytosis in 19% of cases. The median EBV viral load was 2816 copies/mL (range: 555-355,500 copies/mL). Four deaths related to EBV infection were reported. Viral load in these cases also varied widely from 594 to 121,000 copies/mL. Supportive care was administered to 85% of patients, while others received antiviral treatment, steroids, and rituximab. CONCLUSION: Atypical manifestations were common, especially in children with multisystem involvement. EBV should be considered as a potential contributor to a diverse spectrum of clinical presentations, emphasizing the need for comprehensive evaluation and awareness in clinical diagnosis.

INTRODUCCIÓN: La infección por el virus de Epstein-Barr (VEB) tiene una prevalencia mundial superior al 95%. Se considera que en los niños se manifiesta principalmente como mononucleosis infecciosa; sin embargo, en la práctica clínica, a menudo encontramos numerosas manifestaciones atípicas con compromiso multisistémico que llevan a un curso desfavorable. Nuestro objetivo es describir las manifestaciones clínicas y los resultados de la infección por VEB en un hospital pediátrico de tercer nivel en México. MÉTODO: Estudio observacional, transversal, retrospectivo y descriptivo, en el cual se revisaron sistemáticamente los expedientes médicos de pacientes menores de 18 años con una detección positiva de partículas de VEB en sangre periférica en el periodo 2012-2022. RESULTADOS: Se incluyeron 26 pacientes con una mediana de edad de 5 años y predominio de varones (53.8%). El 65% presentaron manifestaciones graves y atípicas, incluyendo enfermedades respiratorias, hepáticas, hematooncológicas y autoinmunitarias. Los síntomas más frecuentes fueron fiebre (85%) y linfadenopatía (35%). El 54% presentaron manifestaciones atípicas, incluyendo linfohistiocitosis hemofagocítica, neumonía y neoplasia. La anemia, la trombocitopenia y la leucocitopenia fueron comunes, mientras que el 19% presentaron linfocitosis. La media de la carga viral fue de 2816 copias/ml (555-355,500). Se informaron cuatro muertes atribuidas a la infección por VEB, con valores de carga viral de 594 a 121,000 copias/ml. El 85% de los pacientes recibieron solo tratamiento sintomático, mientras que otros recibieron antivirales, esteroides y rituximab. CONCLUSIÓN: Las manifestaciones atípicas se observaron comúnmente, en especial en niños con compromiso multisistémico. El VEB debe considerarse como un potencial factor contribuyente en el diagnóstico de una amplia gama de manifestaciones clínicas.

Intramuscular vascular malformations in pediatric patients: a retrospective study in a vascular anomalies clinic.

BACKGROUND: Intramuscular vascular malformations (IVMs) are rare developmental congenital structural abnormalities. Their clinical diagnosis is difficult, and imaging studies are essential to determine the type and extent of vessels involved. Treatment can be challenging and must be managed by a multidisciplinary team. METHODS: A descriptive, observational, retrospective, longitudinal study of clinical records of patients diagnosed with IVMs who were evaluated at the vascular anomalies clinic from January 2011 to December 2021 was performed. Demographic, clinical, imaging, diagnosis, treatment, and response data were collected. RESULTS: Seven patients (five females and two males) with a mean age of 13.66 years (standard deviation 5.82 years) were included in the study. In all cases, the clinical diagnosis was venous and lymphatic malformation. The radiological findings were dilated and tortuous vascular structures or multilobulated lesions with septa inside, with or without vascular flow; these findings allowed diagnosis in all cases. Treatment modalities included sclerotherapy in five patients, surgical resection in two, medical treatment with sirolimus in three, and surveillance in one. Subsequent clinical evolution was favorable in all patients, with decreased pain in six (partial in four and total in two) and size reduction in one patient. CONCLUSION: IVMs in our pediatric population most frequently affect the lower extremities. The main symptoms and signs were pain on exertion and volume increase. Treatment can be challenging given the extension and depth of the malformations, so a combination of therapeutic modalities may be necessary to obtain the best outcome.

INTRODUCCIÓN: Las malformaciones vasculares intramusculares (MVI) son anomalías estructurales congénitas del desarrollo raras. Su diagnóstico clínico es difícil y los estudios de imagen son fundamentales para determinar su tipo y extensión. Su tratamiento puede ser un desafío y debe ser dirigido por un equipo multidisciplinario. MÉTODOS: Se realizó un estudio descriptivo, observacional, retrospectivo y longitudinal de los expedientes clínicos de pacientes con diagnóstico de MVI que fueron valorados en la Clínica de Anomalías Vasculares desde enero 2011 a diciembre 2021. Se recolectaron datos demográficos, clínicos, imagenológicos, diagnóstico, tratamiento y respuesta al mismo. RESULTADOS: Se incluyeron 7 pacientes (5 mujeres y 2 hombres) con una edad media de 13.66 años (DE 5.82 años). En todos, el diagnóstico clínico fue malformación venosa y/o linfática. Los hallazgos radiológicos mediante ultrasonido y/o resonancia magnética nuclear fueron estructuras vasculares dilatadas y tortuosas o lesiones multilobuladas con septos en su interior, con o sin flujo vascular; y en todos los casos permitieron hacer el diagnóstico. El tratamiento fue escleroterapia en 5 pacientes, resección quirúrgica en 2, tratamiento con Sirolimus en 3 y vigilancia en 1. La evolución clínica posterior fue favorable en todos, con disminución del dolor en 6 (parcial en 4 y total en 2) y reducción del tamaño en 1 paciente. CONCLUSIÓN: Las MVI en nuestra población pediátrica, afectan con mayor frecuencia las extremidades inferiores. Los principales síntomas fueron dolor de esfuerzo y aumento de volumen. Su tratamiento puede ser un reto dada su extensión y profundidad, por lo que la combinación de modalidades terapéuticas puede ser necesarias para obtener el mejor desenlace.

Clinical and epidemiological characteristics of pilomatricomas in a Mexican pediatric population.

BACKGROUND: Pilomatricoma is a common benign adnexal neoplasm in children. There are few epidemiological studies on this subject, with most relying solely on descriptive statistics. METHODS: A cross-sectional study conducted in two tertiary hospitals in Mexico City from January 2017 to December 2023. Clinical and electronic records of patients with histopathological diagnosis of pilomatricoma, both sexes, under 18 years old, with any type of present comorbidity were selected. Records of patients with diagnosis not confirmed by histopathology or incomplete records were not included in the study. RESULTS: Fifty-two cases with pilomatrixoma were included in the study, showing a total of 74 lesions. About 23.1% of the cases had multiple pilomatrixomas. 40.4% of the cases experienced pain; this symptom was associated with lesions > 15 mm in diameter and with multiple pilomatrixomas. Risk factors for lesions > 15 mm included age under 8 years, positive tent sign, tumor evolution longer than a year, and a non-classical clinical variety. The head and neck were the most commonly affected areas. The left upper extremity presented larger pilomatrixomas (median 18.5 mm) and occurred more frequently in adolescent patients (mean age 12.1 years) compared to other body areas. CONCLUSIONS: Pilomatrixoma in children shows clinical diversity, with specific findings based on size, number, and anatomical location.

INTRODUCCIÓN: El pilomatricoma es una neoplasia anexial benigna frecuente en la infancia. Hay muy pocos estudios epidemiológicos al respecto y la mayoría solo han utilizado estadística descriptiva. MÉTODOS: Estudio transversal realizado en dos hospitales de concentración de la Ciudad de México de enero de 2017 a diciembre de 2023. Se seleccionaron expedientes clínicos y electrónicos de pacientes con diagnóstico histopatológico de pilomatricoma, ambos sexos, menores de 18 años, con cualquier tipo de comorbilidad presente. No se incluyeron los expedientes de pacientes con diagnóstico no confirmado por histopatología o expediente incompleto. RESULTADOS: Se incluyeron 52 casos con diagnóstico de pilomatricoma que mostraron un total de 74 lesiones. El 23.1% de los pacientes tuvieron pilomatricomas múltiples. El 40.4% experimentaron dolor; este signo se asoció con lesiones de diámetro superior a 15 mm y pilomatricomas múltiples. La edad menor de 8 años, el signo de la tienda de campaña positivo, un tiempo de evolución mayor de 1 año y una variedad clínica no clásica son factores de riesgo asociados con las lesiones mayores de 15 mm. La cabeza y el cuello fueron las áreas más comúnmente afectadas por estos tumores. La extremidad superior izquierda presento pilomatricomas de mayor tamaño (mediana 18.5 mm), y ocurrieron más en pacientes adolescentes (media 12.1 años), en comparación con otras áreas del cuerpo. CONCLUSIONES: El pilomatricoma en niños muestra diversidad clínica. Presenta hallazgos y asociaciones específicas según el tamaño, el número y la ubicación anatómica.

Oral glucose tolerance test curve shape in Mexican children and adolescents with and without obesity.

OBJECTIVES: Mexican children with obesity are at a higher risk of developing type 2 diabetes mellitus (T2DM). The aim of the study was to compare oral glucose tolerance test (OGTT) characteristics: time of peak glucose, glucose level ≥155 mg/dL at 1 h, presence of metabolic syndrome (MetS), sensitivity, secretion, and oral disposition index (oDI) in children with and without obesity, according to oral glucose tolerance curve shape: monophasic or biphasic. METHODS: Cross-sectional study including 143 children. Groups were divided into (a) obese: biphasic (B-Ob) (n=55) and monophasic (M-Ob) (n=50), (b) without obesity: biphasic (B-NonOb) (n=20) and monophasic (M-NonOb) (n=18). RESULTS: Late glucose peak was more frequent in the M-Ob group (p<0.001). Glucose levels ≥155 mg/dL and MetS were more frequent in the M-Ob group but did not show significance. The groups with obesity (biphasic and monophasic) had higher indices of insulin resistance and insulin secretion compared to the nonobese groups (biphasic and monophasic) (p<0.001). AUC glucose was higher in the M-Ob group (p<0.05), and AUC insulin was higher in the M-NonOb group. oDI (Matsuda) was significantly lower in the M-Ob group compared to the other groups (p<0.001), and oDI-HOMA IR was higher in M-NonOb group (p=0.03). CONCLUSIONS: All OGTT parameters could help to identify Mexican children at increased risk of developing T2DM, not only fasting plasma glucose and 2 h glucose. M-Ob in non-T2DM Mexican children reflects an early defect in glucose metabolism. Higher level of IR indexes in M-NonOb vs. B-NonOb could indicate an increased risk for T2DM of genetic origin.

Correlations among satisfaction parameters after orthodontic treatment.

OBJECTIVE: This study assessed patient's satisfaction after orthodontic treatment in the postgraduate orthodontic clinic of the Dental School at the University of Athens (Athens, Greece), and investigated possible correlations between satisfaction after orthodontic treatment and life satisfaction, alongside the influence of age, gender, severity of initial orthodontic malocclusion and duration of retention period. MATERIAL AND METHODS: Patients aged 12 years and above, who had recently completed comprehensive orthodontic treatment, participated completing two questionnaires: a 37-item questionnaire, validated for assessing orthodontic treatment satisfaction; and the 5-item Satisfaction with Life Scale, a valid and reliable measure of life satisfaction. Scores from each questionnaire were summed for each patient. Demographic details, Index of Orthodontic Treatment Need (IOTN) and the duration of the retention period up to questionnaire completion were collected. Multiple regression analysis assessed the relationship between the questionnaires and the evaluated variables. RESULTS: A total of 150 patients answered the questionnaires, being 82 women (55%) and 68 men (45%). The mean age of patients was 18.87 ± 5.97 years (range: 12-47). Most patients expressed satisfaction with treatment outcomes (grades 5 and 6). Satisfaction with orthodontic treatment showed a significant correlation with life satisfaction (p=0.002), but not with gender, age, dental/esthetic components of IOTN, or the duration of the retention period. CONCLUSION: Satisfaction after orthodontic treatment exhibited a significant correlation with life satisfaction, but it was not affected by gender, age, dental/esthetic components of IOTN, or the duration of the retention period.

Focus on leveling the hidden: managing impacted maxillary canines.

INTRODUCTION: The long pathway that the canines take as they emerge into the maxillary arch makes them vulnerable to disruption during their natural emergence time. The process of planning treatment for impacted maxillary canine (IMC) presents significant challenges, underscoring the need for careful consideration and expertise. OBJECTIVE: The aim of this article was to shed light on these complexities by discussing clinical case studies involving IMC, providing insights into the intricacies of their management. CONCLUSIONS: The management of IMC within orthodontics presents a multifaceted challenge that include the necessity for precise diagnostic processes, prudent use of cone beam computed tomography (CBCT), the strategic selection between open and closed exposure techniques, a in-depth understanding of the specific orthodontic biomechanics involved, and a keen awareness of potential adverse outcomes such as ankylosis, prolonged treatment times, root resorption, and additional complications.

Descriptive analysis of the cases published in the Align® Global Gallery.

INTRODUCTION: Social media enhanced access to information, making it easier to share dental treatments. OBJECTIVE: This study aimed to conduct a descriptive analysis of the clinical cases published on the Align® Global Gallery platform. MATERIAL AND METHODS: A retrospective cross-sectional study of 1,582 cases was conducted, data extracted referred to the following basic information: case number; patient's age; reported gender; Invisalign® package modality; treatment time; aligner exchange protocol; total number of aligners per arch; type of retainers, and inclusion of initial and final panoramic and cephalometric radiographs. RESULTS: The majority were young (mean age 24.6 years, SD = 11.6), female patients (69.1%) with Class I malocclusion (39.4%) and crowding (77.9%). Comprehensive treatment was common (66.5%), with an average treatment time of 18 months (SD = 8.56; 95% CI = 17.6-18.5), with the most frequently reported aligner exchange protocol being 7 days (49.5%), with an average of 50.6 aligners in the upper arch (SD = 26.9; 95% CI = 49.2-51.9), and 48.7 in the lower arch (SD = 26.1; 95% CI = 47.4-50.0). Arch expansion (66.9%) and interproximal reduction (59.7%) were common approaches, while extractions were rare (4.3%). In most cases, initial lateral cephalometric (80.4%) and panoramic (93.3%) radiographs were presented. However, the final radiograph count dropped, with lateral cephalometric at 69.2%, and panoramic at 82.2% of cases. CONCLUSION: Cases in the Align®Global Gallery mostly feature Class I patients with crowded teeth, treated with expansion and interproximal reduction. The absence of standardized information and post-treatment data restricts the applicability of these findings to broader Invisalign® treatment trends.

Facial soft tissue changes in adolescent patients treated with three different functional appliances: a randomized clinical trial.

INTRODUCTION: Patients with Class II, division 1 malocclusion generally seek treatment to improve facial esthetics. Therefore, the orthodontist needs to know the changes in the soft profile produced by functional appliances. OBJECTIVE: This study evaluated the soft tissue profile changes in patients treated during the peak of the pubertal growth spurt. METHODS: Thirty selected patients were randomized into three treatment groups: Twin Block (TB), Herbst with dental anchorage (HDA), and Herbst with skeletal anchorage (HSA). All patients had computed tomographic images: pretreatment (T1) and after 12 months of active treatment (T2). Twenty-four soft tissue cephalometric measures were analyzed. The normality of all data was assessed by the Shapiro-Wilk test. Intragroup comparisons were analyzed using the t-paired test; the inter-group comparisons were determined through ANOVA and the post-hoc Tukey test. RESULTS: At T1, no significant differences were observed between groups. At T2, in the intragroup comparison, facial soft tissue changes were statistically significant in the three groups for the lower lip, sulcus inferioris, facial soft tissue convexity in HDA group and TB group, and H angle in HDA group and HSA group, and soft tissue pogonium in TB group. In the inter-group comparison, no statistically significant differences were observed. CONCLUSION: It can be concluded that there were significant changes in soft tissue measurements that benefited Class II, division 1 patient's facial profile treated with the functional appliances Twin Block, Herbst, and Herbst with skeletal anchorage. Nevertheless, no significant differences were detected among the effects obtained by the three treatment protocols.

Religiosity and alcohol use in adolescents with orofacial cleft: correlational study.

OBJECTIVE: To evaluate the correlation between religiosity and alcohol use among adolescents with orofacial clefts. METHODS: Cross-sectional study, developed in a Brazilian public and tertiary hospital, between December 2021 and March 2022. Data collection was hybrid, and three instruments were used: Sociodemographic Questionnaire, Durel Religiosity Scale, and the Alcohol Use Disorders Identification Test. For statistical analysis, the following tests were used: χ2, Fisher's Exact, Mann-Whitney and Spearman's Correlation Coefficient, in addition to analyses of linear correlation strength and bivariate logistic regression. The significance level adopted for all tests was 5% (p≤0.05). RESULTS: 370 adolescents participated, with a mean age of 15.2 years (±1.8). Among them, 23 (5.4%) used alcohol riskly or harmfully, being more frequent among male adolescents (p=0.001), those of mixed race (p=0.046), attending high school (p=0.011), with no religion (p<0.001), or who did not attend religious services (p<0.001). Levels of organizational, non-organizational and intrinsic religiosity were significantly lower among adolescents with risky or harmful alcohol use (p=0.005; p<0.001 and p=0.002, respectively). There was a moderate correlation between risky or harmful alcohol use and non-organizational (r=0.31; p=0.002) and intrinsic (r=0.36; p<0.001) religiosity. Male adolescents (p<0.001; OR=6.58), closest in age to 18 years (p<0.001; OR=1.37), and non-practitioners of religion (p<0.001; OR=6. 48) presented higher odds of risky or harmful alcohol use. CONCLUSIONS: Adolescents with higher levels of organizational and intrinsic religiosity used less alcohol, while males, closest in age to 18 years, and non-practitioners of religion presented higher odds of using alcohol riskly or harmfully.

Children and adolescents with sickle cell disease: characteristics and use of medicinal plants.

OBJECTIVE: The aim of this study was to describe the epidemiological characteristics of pediatric patients with sickle cell disease (SCD) and evaluate the use of medicinal plants in these patients concomitantly with their drug treatment. METHODS: This is a review of the medical records of pediatric patients at a public institution with tertiary care. The selection criterion was to be a child or adolescent with SCD undergoing pediatric follow-up at this outpatient clinic. In the medical records of the patients selected, records of the use of plants for medicinal purposes were sought. RESULTS: In total, 154 records (100% of total active patients followed in this clinic) were reviewed: 99 children and 55 adolescents. The predominant genotype was SS (58.4%), followed by SC (29.2%). The use of at least one medication for SCD was reported in 95.5% of the medical records. The use of medicinal plants was reported by 70.1% of patients, with 276 citations in the medical records referring to 64 different types of plants. Six plants were used for the treatment of SCD, the main one being Lemonvine/Ora-pro-nóbis (Pereskia aculeata). The use of medicinal plants was reported for flu-like symptoms and/or COVID-19 (both for prevention and treatment) by 60.5% of the citations, with 35 different plants reported for this use, exclusively or not. This use was followed by pain symptoms (14.2% of citations). CONCLUSIONS: The majority of patients in this study use both conventional and traditional/complementary/alternative medicine, highlighting the need for more studies in the area, with a special focus on patient safety.

Depression symptoms are associated with demographic characteristics, nutritional status, and social support among young adults in Chile: a latent class analysis.

BACKGROUND: Depressive disorders are a critical public health concern in Chile. Nonetheless, there is a lack of evidence regarding the identification of depressive symptom clusters. The objective was to identify depressive symptom clusters among Chilean young adults and examine how demographic, and lifestyle factors as well as social support can influence and predict them. METHODS: Cross-sectional study conducted among 1,000 participants from the Limache cohort 2. A latent class analysis (LCA) was performed to identify depressive symptom clusters, using the Patient Health Questionnaire (PHQ-9). Multinomial logistic regression was then applied to explore the associations between identified classes and potential predictors. The models were adjusted by age and sex. RESULTS: Three latent classes of depressive symptoms were identified: minimal (25.7%); somatic (50.7%) and severe (23.6%). In the severe class for eight out nine depressive symptoms the probabilities were above 50%, and the probability of suicidal ideation was almost a third in this class. Being female (Adjusted Odds ratio [AOR], 2.49; 95% confidence interval [CI] [1.63-3.81]), current smoker (AOR, 1.74; 95% CI [1.15-2.65]), having basic education (AOR, 3.12; 95% CI [1.30-7.53]) and obesity (AOR, 2.72; 95% CI [1.61-4.59]) significantly increased the likelihood of belonging to severe class. Higher social support decreased the odds of being in the somatic (OR, 0.96; 95% CI [0.93-0.98]) and severe (OR, 0.92; 95% CI [0.90-0.94]) classes. CONCLUSIONS: These findings highlight the importance of individualized intervention strategies for depression management. Also, the study suggests that nutritional status and social support should be considered when addressing depression in this population.
