ABSTRACT

El propósito de este estudio fue evaluar la relación entre el rendimiento anaeróbico y la personalidad Grit en taekwondistas estadounidenses, su grado de influencia, así como las diferencias que puedan existir entre sexos. Este estudio tuvo una metodología cuantitativa, descriptiva-correlacional, realizada en una población de (n=121) taekwondistas, vinculados a la USAT. La personalidad Grit fue medida mediante la escala Grit, y el rendimiento anaeróbico a través de la prueba del sprint anaeróbico basado en la carrera (Rast). De acuerdo con los resultados se pudo identificar en hombres, una correlación positiva y significativa entre la capacidad y potencia anaeróbica con el Grit (p<0.005 y p<0.007 respectivamente). Asimismo, estas dos variables se relacionaron significativamente con el Grit (p<0.001) en el total de la muestra. En el caso de las mujeres, no hubo relaciones significativas. El índice de fatiga no presentó correlaciones significativas. La personalidad Grit influyó hasta un 14% en la capacidad y potencia anaeróbica en hombres (p<0.001 y p<0.002, respectivamente) y un 12% en estos dos mismos aspectos para la muestra total (p<0.000 en ambos casos). Finalmente, los hallazgos indican una relación entre la potencia, capacidad anaeróbica con la personalidad Grit en hombres y en el total de la muestra, con una influencia significativa del Grit en el rendimiento anaeróbico. No se encontraron tales relaciones en mujeres. Aunque no se hallaron diferencias significativas por sexo en el Grit, capacidad y potencia anaeróbica, sí que se encontró en el índice de fatiga, indicando una disparidad en la resistencia a la fatiga entre sexos.


The purpose of this study was to assess the relationship between anaerobic performance and Grit personality in American taekwondo practitioners, its degree of influence, as well as any differences that may exist between genders. This study employed a quantitative, descriptive-correlational methodology, conducted on a population of (n=121) taekwondo practitioners affiliated with the USAT. Grit personality was measured using the Grit Scale, and anaerobic performance was assessed through the Anaerobic Sprint Test based on running (Rast). According to the results, a positive and significant correlation between anaerobic capacity and power with Grit was identified in men (p<0.005 and p<0.007 respectively). Likewise, these two variables were significantly related to Grit (p<0.001) in the total sample. In the case of women, there were no significant relationships. The fatigue index showed no significant correlations. Grit personality influenced up to 14% in anaerobic capacity and power in men (p<0.001 and p<0.002, respectively) and 12% in these two aspects for the total sample (p<0.000 in both cases). Finally, the findings indicate a relationship between power, anaerobic capacity, and Grit personality in men and the total sample, with a significant influence of Grit on anaerobic performance. Such relationships were not found in women. Although no significant gender differences were found in Grit, anaerobic capacity, and power, differences were found in the fatigue index, indicating a disparity in fatigue resistance between genders.

ABSTRACT

SUMMARY: The identification of children and adolescents who are at risk of sarcopenic obesity development often requires specialized equipment and expensive test procedures. Therefore, the establishment of cheaper and faster methods would be greatly useful, especially if they could be applied in the field. The study's objective was to establish if identification of female adolescents who suffer the risk of developing sarcopenic obesity can be obtained through the standing-long-jump test application. To achieve the research objectives, various anthropometric and body composition measurements were performed and lower limb explosive strength was assessed using the standing long jump fitness test. The research was conducted on a sample of 535 female respondents randomly selected from 9 elementary schools in the Skopje region of the Republic of North Macedonia. The respondents were divided into quintiles according to BMI z-scores, and the arithmetic means and SD about muscle-to-fat ratio were calculated for each quintile. The cutoff was determined based on the mean and standard deviation of the muscle-to-fat ratio for the 3rd quintile of BMI and the percentage of respondents with sarcopenic obesity was examined. The optimal cut-off value of the long jump fitness test results for predicting sarcopenic obesity in an adolescent girl showed that the area under the ROC curve was 0.781 (95 % CI 0.743-0.815). The standing-long-jump test values, on grounds of odds ratio (OR 95 % CI) about the girls at risk of sarcopenic obesity development, which was identified on muscle-to-fat ratio base, were 8.76 (4.39 - 17.54, p 0.001). It can be used to predict sarcopenic obesity presence in female adolescents, which can be vital in case of health intervention.


La identificación de niños y adolescentes que corren riesgo de desarrollar obesidad sarcopénica a menudo requiere equipos especializados y procedimientos de pruebas costosos. Por lo tanto, el establecimiento de métodos más baratos y rápidos sería de gran utilidad, especialmente si pudieran aplicarse en el campo. El objetivo del estudio fue establecer si la identificación de mujeres adolescentes que sufren riesgo de desarrollar obesidad sarcopénica se puede obtener mediante la aplicación de la prueba de salto de longitud de pie. Para lograr los objetivos de la investigación, se realizaron diversas mediciones antropométricas y de composición corporal y se evaluó la fuerza explosiva de los miembros inferiores mediante la prueba de aptitud de salto de longitud de pie. La investigación se realizó con una muestra de 535 mujeres encuestadas seleccionadas al azar de 9 escuelas primarias de la región de Skopje, en la República de Macedonia del Norte. Los encuestados se dividieron en quintiles según las puntuaciones z del IMC, y se calcularon las medias aritméticas y la DE sobre la relación músculo-grasa para cada quintil. El límite se determinó en función de la media y la desviación estándar de la relación músculo-grasa para el tercer quintil del IMC y se examinó el porcentaje de encuestados con obesidad sarcopénica. El valor de corte óptimo de los resultados de la prueba de condición física de salto de longitud para predecir la obesidad sarcopénica en una adolescente mostró que el área bajo la curva ROC fue 0,781 (IC del 95 %: 0,743-0,815). Los valores de la prueba de salto de longitud de pie, sobre la base del odds ratio (OR IC del 95 %) sobre las niñas en riesgo de desarrollar obesidad sarcopénica, que se identificó sobre la base del ratio músculo-grasa, fueron 8,76 (4,39 - 17,54, p. 0,001). Puede utilizarse para predecir la presencia de obesidad sarcopénica en adolescentes, lo que puede ser vital en caso de intervención sanitaria.

ABSTRACT

INTRODUCCIÓN: En la diarrea asociada a Clostridioides dfficile (DACD) leve-moderada se recomienda tratar con vancomicina por sobre metronidazol, a pesar de su difícil acceso y poca evidencia en el medio ambulatorio. OBJETIVO: Comparar la tasa de cura clínica y recurrencia entre vancomicina y metronidazol en adultos chilenos con primer episodio leve-moderado de DACD de manejo ambulatorio. MÉTODOS: Cohorte retrospectiva entre enero 2015 y diciembre 2020 en centros de una red de salud universitaria de pacientes de ≥ 18 años con DACD tratados ambulatoriamente. RESULTADOS: Se obtuvieron 161 pacientes, 59% mujeres, edad promedio de 53 años (entre 18 y 94 años). De ellos, 109 (67,7%) usaron metronidazol y 52 (32,3%) vancomicina. En el análisis multivariado ajustado por edad y comorbilidades se obtuvo un OR 3,00 (IC 95% 1,12-9,59) para cura clínica y 0,27 (IC 95% 0,06-0,88) para recurrencia a ocho semanas, ambos a favor de vancomicina, sin diferencias en recurrencia a 12 meses, necesidad de hospitalización o mortalidad. CONCLUSIÓN: La terapia con vancomicina comparada contra metronidazol en el tratamiento ambulatorio de la infección leve-moderada por C. dfficile se asocia a mayor cura clínica y menor tasa de recurrencia a corto plazo, sin diferencias en desenlaces a largo plazo.


BACKGROUND: Recommended treatment against mild cases of Clostridioides difficile associated diarrhea is vancomycin despite the difficulties of access compared to metronidazole. AIM: To compare the effectiveness of vancomycin and metronidazole in Chilean adults with first mild-moderate episode of Clostridiodes difficile infection (CDI). METHODS: Retrospective cohort of patients with CDI between January 2015 and December 2020 treated in centers of a university health network. The patients were adults treated for C. difficile infection on an outpatient basis. Recurrent and severe cases were excluded. Outcomes included clinical cure and recurrence rate. RESULTS: Data from 161 patients was recovered. Fifty-nine percent were women and average age was 53 (18-94). One hundred and nine patients were treated with metronidazole (67.7%) and 52 (32.3%) used vancomycin. Multivariate analysis adjusted by age and comorbidities showed an Odds Ratio of 3.00 (IC 95% 1.12-9.59) for clinical cure and 0.27 (IC 95% 0.06-0.88) for 8-week recurrence rate, both in favor of vancomycin, without differences in 12-month recurrence rate, hospitalization rate nor mortality. CONCLUSIONS: Vancomycin is associated with better short-term outcomes in the treatment of outpatient mild-moderate first episode C. difficile infection, without differences in long term recurrence or mortality when compared with metronidazole.

ABSTRACT

SUMMARY: The handgrip strength is used as a means of individual's health prediction during life. It is used as an indicator of the nutrition status, bone fragility, presence of sarcopenia and it correlates with certain diseases and clinical complications. The research goal was to analyze the results of the hand dynamometry test, based on the chronological and biological age, and to offer normative and referent standards about children and adolescents from the Republic of North Macedonia. The study was conducted on a sample of 4031 respondents of both sexes at the age 6-14 years. In order to achieve the research goals, the measured characteristics were of the weight, height, sitting height and handgrip strength. The body mass index and biological maturity values (APHV) were obtained by using formulas. On the basis of the obtained results, it can be concluded that statistically significant differences in handgrip strength are established between the boys and girls of all age categories. Also, statistically significant differences between boys and girls are established in the hand dynamometry test of all APHV levels. In general, the use of the APHV allows a better categorization of the performance of the studied children and adolescents. With boys, the correlation between the chronological age and test was 68 %, and with girls - 77 %. The normative referent standards of the hand dynamometry test are presented in percentiles for both sexes. Thye hand dynamometry test's results during childhood and adolescence should be analyzed and interpret on the basis of biological age, and not on the chronological age. These tools can help specialists who work with children and adolescents in ethnic and epidemiological context.


La fuerza de prensión se utiliza como medio para predecir la salud del individuo durante la vida. Se utiliza como indicador del estado nutricional, fragilidad ósea, presencia de sarcopenia y se correlaciona con determinadas enfermedades y complicaciones clínicas. El objetivo de la investigación fue analizar los resultados de la prueba de dinamometría manual, con base en la edad cronológica y biológica, y ofrecer estándares normativos y referentes sobre niños y adolescentes de la República de Macedonia del Norte. El estudio se realizó en una muestra de 4031 encuestados de ambos sexos con edades comprendidas entre 6 y 14 años. Para lograr los objetivos de la investigación, las características medidas fueron el peso, la altura, la altura al sentarse y la fuerza de prensión. El índice de masa corporal y los valores de madurez biológica (APHV) se obtuvieron mediante fórmulas. Sobre la base de los resultados obtenidos, se puede concluir que se establecen diferencias estadísticamente significativas en la fuerza de prensión manual entre niños y niñas de todas las categorías de edad. Asimismo, se establecen diferencias estadísticamente significativas entre niños y niñas en la prueba de dinamometría manual de todos los niveles APHV. En general, el uso del APHV permite una mejor categorización del desempeño de los niños y adolescentes estudiados. En los niños, la correlación entre la edad cronológica y la prueba fue del 68 %, y en las niñas, del 77 %. Los estándares normativos referentes de la prueba de dinamometría manual se presentan en percentiles para ambos sexos. Los resultados de la prueba de dinamometría manual durante la infancia y la adolescencia deben analizarse e interpretarse en función de la edad biológica y no de la edad cronológica. Estas herramientas pueden ayudar a los especialistas que trabajan con niños y adolescentes en un contexto étnico y epidemiológico.

ABSTRACT

ABSTRACT Objective: To determine the unstimulated salivary flow, pH, and buffering capacity and their associations with systemic conditions and medication use in independently living aged. Material and Methods: This cross-sectional study included 72 participants with a minimum of 60 years recruited in Belo Horizonte, Brazil. A questionnaire was used to collect age, sex, presence of systemic diseases, and medications in continuous use. Salivary data collection was performed to determine unstimulated salivary flow, pH, and buffering capacity. Descriptive, bivariate, and multivariate analyses were performed (p<0.05). Results: Most of the sample had at least one systemic disease (81.9%) and used at least one medication (79.2%). Female participants (p=0.01), those with five or more systemic diseases (p<0.01), and hypertension (p=0.04) had reduced salivary flow. Participants with systemic diseases (p=0.02), taking any medication (p=0.04), in a polypharmacy regimen, and presenting hypertension (p=0.02) had more acidic salivary pH. Participants with diabetes had average salivary buffering capacity (p=0.02). In the adjusted multiple regression models, no explanatory variable was significantly associated with the salivary outcomes. Conclusion: Systemic alterations and medication use appear to be related to salivary changes in older adults. Integrative assessment of older adults is fundamental to identifying and controlling the factors that may modify their salivary characteristics.

ABSTRACT

ABSTRACT Objective: To assess the impact of Molar Incisor Hypomineralization (MIH) and confounding factors on oral health-related quality of life (OHRQoL) according to the perception of 8 to 10-year-old children and their parents/caregivers. Material and Methods: A cross-sectional study including 403 students aged 8-10 years was carried out, in which OHRQoL was measured using the Child Perceptions Questionnaire administered to both children and parents/caregivers. The diagnosis of MIH was performed according to the previously proposed index. Dental caries experience, malocclusion, and sociodemographic factors were evaluated as confounders. Cluster analysis and Poisson regression with robust variance (p<0.05) were performed. Results: The prevalence of MIH was 13.4%. Parents/caregivers of children with MIH in incisors showed a higher impact prevalence in the emotional well-being domain (PR=1.92; 95%CI=1.16-3.19). Children with hypoplasia had a higher prevalence of negative impact on OHRQoL in the oral symptoms domain (PR=1.51; 95%CI=1.03-2.23). According to the perception of parents/caregivers, dental caries experience had a negative impact on the quality of life of students in the emotional well-being domain (PR=4.19; 95%CI=1.06-16.49) and in the total questionnaire score (PR=3.21; 95%CI=1.06-9.71). Conclusion: According to the perception of parents/caregivers, children with MIH in incisors showed a greater impact on OHRQoL. Additionally, the presence of hypoplasia affected the self-perception of OHRQoL in children, and caries experience influenced the OHRQoL of children, as perceived by parents/caregivers.

ABSTRACT

Abstract Objective: To estimate the incidence of dental caries and associated factors in the school period from six/seven to ten years of age. Material and Methods: A longitudinal study involving 168 children was followed up between 2015 and 2019 in the municipality of Palhoça, Brazil. The dependent variable was the caries incidence rate in the mixed dentition. The independent variables included information regarding demographic and socioeconomic status. Multivariate analyzes were carried out using Poisson Regression with a robust estimator. Variables with p <0.20 in the bivariate analysis were included in the adjusted model. Relative risks were estimated, as well as 95% confidence intervals. Results: Of 168 followed schoolchildren, 32 developed the disease, providing an incidence rate of 19.0%. Female children had a 10% higher risk [RR = 1.10 (95% CI 1.03; 1.18)] of developing caries than males. Also, children born from fathers with ≤ 8 years of schooling at baseline had a 9% higher risk [RR = 1.09 (95% CI 1.01; 1.16)] of developing dental caries compared to fathers with higher education. Conclusion: The incidence of dental caries in a four-year period was 19.0%. Females and children born from fathers with a lower level of education showed higher incidence rates.

ABSTRACT

ABSTRACT OBJECTIVE This study aims to propose a comprehensive alternative to the Bland-Altman plot method, addressing its limitations and providing a statistical framework for evaluating the equivalences of measurement techniques. This involves introducing an innovative three-step approach for assessing accuracy, precision, and agreement between techniques, which enhances objectivity in equivalence assessment. Additionally, the development of an R package that is easy to use enables researchers to efficiently analyze and interpret technique equivalences. METHODS Inferential statistics support for equivalence between measurement techniques was proposed in three nested tests. These were based on structural regressions with the goal to assess the equivalence of structural means (accuracy), the equivalence of structural variances (precision), and concordance with the structural bisector line (agreement in measurements obtained from the same subject), using analytical methods and robust approach by bootstrapping. To promote better understanding, graphical outputs following Bland and Altman's principles were also implemented. RESULTS The performance of this method was shown and confronted by five data sets from previously published articles that used Bland and Altman's method. One case demonstrated strict equivalence, three cases showed partial equivalence, and one showed poor equivalence. The developed R package containing open codes and data are available for free and with installation instructions at Harvard Dataverse at https://doi.org/10.7910/DVN/AGJPZH. CONCLUSION Although easy to communicate, the widely cited and applied Bland and Altman plot method is often misinterpreted, since it lacks suitable inferential statistical support. Common alternatives, such as Pearson's correlation or ordinal least-square linear regression, also fail to locate the weakness of each measurement technique. It may be possible to test whether two techniques have full equivalence by preserving graphical communication, in accordance with Bland and Altman's principles, but also adding robust and suitable inferential statistics. Decomposing equivalence into three features (accuracy, precision, and agreement) helps to locate the sources of the problem when fixing a new technique.

ABSTRACT

Introdução: Algumas arboviroses transmitidas por vetores como Aedes aegypti e Culex spp. são consideradas de grande importância epidemiológica, entre estas, destacam-se a dengue, Zika, chikungunya, febre amarela e febre do Nilo ocidental. A transmissão dos arbovírus ocorre enquanto as fêmeas infectadas realizam a hematofagia e as atuais medidas que visam a redução dessas arboviroses na população se dão principalmente com foco na redução da população de mosquitos. Índices de vigilância entomológica fazem parte das rotinas de programas de controle. Estudos recentes têm questionado a eficácia da utilização de índices de formas imaturas do vetor para predição do risco de transmissão de arboviroses e associação com incidência de casos. Isso indica que realizar a vigilância com a forma adulta dos vetores pode ser uma alternativa de maior eficácia. Objetivos: Estimar, predizer e mapear a infestação por Ae. aegypti e o Culex spp. associadas a variáveis de uso e ocupação do solo no município de Campinas/SP no período de verão entre os anos de 2021 a 2023. Material e Métodos: Trata-se de um estudo transversal realizado por meio de coletas mensais de mosquitos adultos realizadas em 200 armadilhas BG MosquititoTM distribuídas aleatoriamente na área urbana de Campinas. Foram realizadas regressões múltiplas em um contexto bayesiano e geoestatístico utilizando a abordagem de aproximações de Laplace aninhadas e integradas e equações diferenciais parciais estocásticas. Foram consideradas como covariáveis o Índice Brasileiro de Privação (IBP) e informações sobre uso e ocupação do solo obtidas de imagens de satélite. Resultados: O melhor modelo de regressão para o número de Ae. aegypti fêmeas encontrou associação positiva com o IBP, uma medida do nível socioeconômico, e árvores. Quanto aos machos, o melhor modelo mostrou associação positiva com cimento e telha de zinco. O melhor modelo para o total de mosquitos Ae. aegypti mostrou associação positiva com o IBP, cimento e árvore e o mesmo ocorreu para Culex spp. Foram elaborados mapas com a predição da quantidade de mosquitos para cada modelo considerando a distribuição das covariáveis presentes na área de estudo. Conclusões: Com esse estudo, foi possível modelar as quantidades de fêmeas, machos e total de Ae. aegypti e total de Culex spp., com base nas informações obtidas com a partir da instalação das armadilhas de adultos, e predizer os níveis de infestação para todos os locais da área de estudo. Variáveis socioeconômicas e de uso e ocupação do solo mostraram-se associadas aos números de mosquitos coletados, com exceção do nível socioeconômico para os machos de Ae. aegypti. Os resultados mostram que a utilização dessas covariáveis nas modelagens foram úteis para melhorar as predições nos locais não amostrados. Nosso estudo mostrou ser possível identificar áreas de maior risco para infestação de forma independente dos limites administrativos da área de estudo, quer sejam bairros ou distritos. Além disso, mostrou ser viável o uso de armadilhas de adultos para realização de vigilância entomológica.


Introduction: Some arboviruses transmitted by vectors such Aedes aegypti and Culex spp. are considered of great epidemiological importance, among which dengue, Zika and chikungunya, yellow fever and West Nile fever stand out. The transmission of arboviruses occurs while infected females are carrying out hematophagy, and current measures aimed at reducing these arboviruses in the population are mainly focused on reducing the mosquito population. Entomological surveillance indices are part of the routines of control programs. Recent studies have questioned the effectiveness of using indices of immature forms of the vector to predict the risk of arbovirus transmission and association with the incidence of cases. This indicates that carrying out surveillance with the adult form of the vectors may be a more effective alternative. Objectives: Estimate, predict and map the infestation of Ae. aegypti and Culex spp. associated with land use and occupation variables in the city of Campinas (SP) in the summer period between 2021 to 2023. Material and Methods: This is a cross-sectional study carried out through monthly collections of adult mosquitoes in 200 BG MosquititoTM traps randomly distributed in the urban area of Campinas. Multiple regressions were performed in a Bayesian and geostatistical context using the approach of nested and integrated Laplace approximations and stochastic partial differential equations. The Brazilian Deprivation Index (IBP) and information on land use and occupation obtained from satellite images were considered as covariates. Results: The best regression model for the number of female Ae. aegypti found a positive association with the IBP, a measure of socioeconomic status, and trees. As for males, the best model considered showed a positive association with cement and zinc tiles. The best model for the total number of Ae. aegypti showed a positive association with IBP, cement and trees, as the same occurred for Culex spp. Conclusions: With this study, it was possible to model the numbers of females, males and total Ae. aegypti and total Culex spp., based on the information obtained from the installation of adult traps, and to predict the infestation levels for all locations in the study area. Socioeconomic and land use and occupation variables were associated with the numbers of mosquitoes collected, with the exception of the socioeconomic level for males of Ae. aegypti. The results show that the use of these covariates in the models was useful to improve predictions in the non-sampled locations. Our study showed that it is possible to identify areas of greater risk for infestation independently of the administrative boundaries of the study area, whether they are neighborhoods, districts. Furthermore, it was shown to be feasible to use adult traps to carry out entomological surveillance.

ABSTRACT

ABSTRACT Objective Evaluate the food consumption of the participants of the Cohort of Universities of Minas Gerais, according to the degree of processing, and its relationship with socioeconomic, behavioral, and individual factors. Methods A total of 4,124 individuals from the baseline of the Cohort of Universities of Minas Gerais (2016 and 2018) participated in this study. Food consumption was self-reported by completing an online Food Frequency Questionnaire. The foods were divided into 3 groups: Group 1, in natura, minimally processed foods, culinary ingredients and culinary preparations; Group 2, processed foods; Group 3, ultra-processed foods. A hierarchical multiple linear regression model was used to verify the associated factors. Results Regarding the factors associated with food consumption, it is noteworthy that Group 1 was positively associated with the practice of physical activity, female gender, age, "non-white" skin color, and the presence of diabetes Mellitus; and negatively with "not married/without stable union" marital status, alcohol abuse, tobacco use, obesity, and depression. Considering Group 2, it was positively associated with alcohol abuse, tobacco use, and age; and negatively with physical activity, female gender, and "non-white" skin color. As for Group 3 it was positively associated with a marital status of "not married/without stable union", obesity, and depression; and negatively with physical activity, age, "non-white" skin color, and presence of diabetes Mellitus. Conclusion The factors that are in at least one of the final hierarchical linear regression models stand out: marital status, physical activity, alcohol abuse, tobacco use, sex, age, skin color, obesity, diabetes mellitus, and depression.

ABSTRACT

SUMMARY: Colon adenocarcinoma (COAD) is a prevalent disease worldwide, known for its high mortality and morbidity rates. Despite this, the extent of investigation concerning the correlation between COAD's CLCA1 expression and immune cell infiltration remains insufficient. This study seeks to examine the expression and prognosis of CLCA1 in COAD, along with its relationship to the tumor immune microenvironment. These findings will offer valuable insights for clinical practitioners and contribute to the existing knowledge in the field. In order to evaluate the prognostic significance of CLCA1 in individuals diagnosed with colorectal cancers, we conducted a comprehensive analysis using univariate and multivariate Cox regression models along with receiver operating characteristic curve (ROC) analysis. This study was performed on the patient data of COAD obtained from The Cancer Genome Atlas (TCGA) database. Nomograms were developed to anticipate CLCA1 prognostic influence. Furthermore, the CLCA1 association with tumor immune infiltration, immune checkpoints, immune checkpoint blockade (ICB) response, interaction network, and functional analysis of CLCA1-related genes was analyzed. We found that Colon adenocarcinoma tissues significantly had decreased CLCA1 expression compared to healthy tissues. Furthermore, the study revealed that the group with high expression of CLCA1 demonstrated a significantly higher overall survival rate (OS) as compared to the group with low expression. Multivariate and Univariate Cox regression analysis revealed the potential of CLCA1 as a standalone risk factor for COAD. These results were confirmed using nomograms and ROC curves. In addition, protein-protein interaction (PPI) network analysis and functional gene enrichment showed that CLCA1 may be associated with functional activities such as pancreatic secretion, estrogen signaling and cAMP signaling, as well as with specific immune cell infiltration. Therefor, as a new independent predictor and potential biomarker of COAD, CLCA1 plays a crucial role in the advancement of colon cancer.


El adenocarcinoma de colon (COAD) es una enfermedad prevalente a nivel mundial, conocida por sus altas tasas de mortalidad y morbilidad. Sin embargo, el alcance de la investigación sobre la correlación entre la expresión de CLCA1 de COAD y la infiltración de células inmunes sigue siendo insuficiente. Este estudio busca examinar la expresión y el pronóstico de CLCA1 en COAD, junto con su relación con el microambiente inmunológico del tumor. Estos hallazgos ofrecerán conocimientos valiosos para los profesionales clínicos y contribuirán al conocimiento existente en el campo. Para evaluar la importancia de pronóstico de CLCA1 en personas diagnosticadas con cáncer colorrectal, realizamos un análisis exhaustivo utilizando modelos de regresión de Cox univariados y multivariados junto con un análisis de la curva característica operativa del receptor (ROC). Este estudio se realizó con los datos de pacientes de COAD obtenidos de la base de datos The Cancer Genome Atlas (TCGA). Se desarrollaron nomogramas para anticipar la influencia pronóstica de CLCA1. Además, se analizó la asociación de CLCA1 con la infiltración inmunitaria tumoral, los puntos de control inmunitarios, la respuesta de bloqueo de los puntos de control inmunitarios (ICB), la red de interacción y el análisis funcional de genes relacionados con CLCA1. Descubrimos que los tejidos de adenocarcinoma de colon tenían una expresión significativamente menor de CLCA1 en comparación con los tejidos sanos. Además, el estudio reveló que el grupo con alta expresión de CLCA1 demostró una tasa de supervivencia general (SG) significativamente mayor en comparación con el grupo con baja expresión. El análisis de regresión de Cox multivariado y univariado reveló el potencial de CLCA1 como factor de riesgo independiente de COAD. Estos resultados se confirmaron mediante nomogramas y curvas ROC. Además, el análisis de la red de interacción proteína- proteína (PPI) y el enriquecimiento de genes funcionales mostraron que CLCA1 puede estar asociado con actividades funcionales como la secreción pancreática, la señalización de estrógenos y la señalización de AMPc, así como con la infiltración de células inmunes específicas. Por lo tanto, como nuevo predictor independiente y biomarcador potencial de COAD, CLCA1 desempeña un papel crucial en el avance del cáncer de colon.

ABSTRACT

Objective: Assessing whether it is possible screening women with osteoporosis through geometric morphometrics based on panoramic x-ray. Materials and Methods: Leukoderma women, after menopause, 40 years old (or older), with confirmed medical diagnosis of presence, or absence, of osteoporosis through bone densitometry examination. (N = 62). Measurements taken through panoramic X-ray based on geometric morphometrics. All x-rays were taken twice by the same researcher. Procrustes superimposition was assessed through Cartesian coordinates generated from anatomic landmark and semilandmarks. Regression Analysis, Multivariate Analysis of Variance (MANOVA), discriminant function and cross validation analysis, and Thin plate spliness in MorphoJ software were carried out. Subsequently, Fluctuating Asymmetry Analysis (FA) was conducted and ANOVA was performed to assess differences in centroid size. Results: Significant values were recorded for mandible shape (p<0.01) through MANOVA. Significant values (P<0.01) were also found through discriminant function analysis between groups of women with, and without, osteoporosis. Fluctuating asymmetry analysis showed significant differences in mandible shape and size between sides (p<0.01). Conclusions: Geometric morphometrics proved to be effective in screening and identifying elderly leukoderma women with, or without, osteoporosis based on panoramic x-rays. This is a promising technique to diagnose or identify patients with some health condition.

ABSTRACT

La incontinencia urinaria de esfuerzo es la pérdida involuntaria de orina durante una maniobra de esfuerzo físico, ejercicio, estornudo o tos. Afecta aproximadamente al 15% de las mujeres de 30-60 años y su prevalencia es del 30-41%. Aunque existen terapias conservadoras para su manejo, muchas pacientes terminarán necesitando cirugía para su resolución. Las mallas suburetrales son alternativas para el manejo quirúrgico, existiendo dos vías de instalación, la transobturadora (TOT o TVT-O) y la retropúbica (del inglés tension-free vaginal tape o TVT), siendo esta última la que presenta mejores resultados y menos complicaciones posoperatorias. Objetivo: evaluar la tasa de efectividad y las complicaciones de la TVT en la Unidad de Piso Pélvico Femenino del Hospital El Carmen de Maipú entre los años 2015 y 2020. Materiales y Métodos: Se obtuvieron 715 registros de pacientes que fueron sometidas a TVT y se logró contactar telefónicamente con el 60,69% de ellas. Resultados: Los resultados muestran una tasa de efectividad del 94,8% y una tasa de complicaciones del 2,3%. Conclusión: Este estudio aporta evidencia local de los resultados posoperatorios en la IOE en pacientes que requirieron la instalación de una malla suburetal retropúbica, demostrando ser una cirugía altamente efectiva y segura.


Stress urinary incontinence is the involuntary loss of urine during physical exertion, exercise, sneezing, or coughing. It affects approximately 15% of women aged 30-60, with a prevalence of 30-41%. Although there are conservative therapies for its management, many patients will eventually require surgery for resolution. Suburethral sling are considered for surgical management, and there are two installation alternatives, transobturator (TOT or TVT-O) and retropubic (tension-free vaginal tape or TVT), with the latter presenting better results and fewer postoperative complications. Objetive: to evaluate effectiveness rate and complications of the TVT in the Female Pelvic Floor Unit of Hospital El Carmen de Maipú between 2015 and 2020. Materials and Methods: A total of 715 patient records were obtained for those who underwent TVT, and 60.69% of them were successfully contacted by telephone. Results: The results show an effectiveness rate of 94.8% and a complication rate of 2.3%. Conclusion: This study provides local evidence for the results of stress urinary incontinence that required the placement of a retropubic suburethral sling, proving to be a highly effective and safe surgery.

ABSTRACT

Introducción: El cáncer de mama es una causa de muerte evitable en las mujeres de hasta 74 años de edad. Sin embargo, es el cáncer más frecuente y la primera causa de muerte por tumores en esa población. Objetivo: Analizar las tendencias de la mortalidad por cáncer de mama en las mujeres de Argentina entre 2005 y 2020, considerando el grupo de edad y la región geográfica. Método: Estudio cuantitativo y descriptivo con perspectiva sociodemográfica. Se calcularon tasas específicas de mortalidad a partir de datos oficiales y se aplicaron modelos de regresión joinpoint para evaluar su tendencia temporal. Resultados: La tasa de mortalidad ajustada por cáncer de mama disminuyó significativamente (PPCA: −1,5%; IC95%: −1,3% a −0,7%); sin embargo, aumentó en las mujeres de 25 a 34 años (PPCA: 2,3%; IC95%: 1,4% a 3,2%). El descenso registrado se trasladó mayormente a las regiones Centro, Cuyo y Noroeste, mientras que las tasas de mortalidad de las regiones Noreste y Patagónica no variaron significativamente. Conclusiones: No obstante los progresos documentados, se evidencian desafíos para reducir la mortalidad por cáncer de mama en las poblaciones más jóvenes. Asimismo, persisten las desigualdades regionales, lo que destaca la importancia de adaptar las acciones a las necesidades del territorio.


Background: Breast cancer is a preventable cause of death among women up to 74 years of age. However, it is the most common cause of cancer death among this population. Objective: To analyze female breast cancer mortality trends in Argentina between 2005 and 2020, taking into account age groups and geographical regions. Method: Quantitative and descriptive study carried out from a socio-demographic perspective. Specific mortality rates were calculated based on official data, and joinpoint regression models were applied to evaluate time trends in mortality. Results: The adjusted mortality rate attributed to breast cancer decreased significantly (AAPC: −1,5%; CI95%: −1,3% to −0,7%); however, it increased among women aged 25-34 (AAPC: 2,3%; CI95%: 1,4% to 3,2%). Besides, the decreasing of mortality took place mainly in Central, Cuyo and Northwest regions meanwhile the mortality rates from Northeast and Patagonia regions didnt vary significantly. Conclusions: Although progress has been made, there are still some challenges regarding the reduction of breast cancer mortality in young women. In addition, regional disparities remain, highlighting the importance to adapt actions to territorial needs.

ABSTRACT

INTRODUCCIÓN: La resistencia a fármacos antituberculosos está influenciada por las características personales y las condiciones de salud de países en vías de desarrollo. OBJETIVO: Determinar los factores asociados a TB-pre extensamente resistente (TB-PRE XDR) en pacientes del Hospital Nacional Dos de Mayo (HNDM) entre 2017 y 2019. PACIENTES Y MÉTODO: Se desarrolló un estudio caso control no pareado, definiendo como caso al paciente con TB- PRE XDR y como control al paciente con TB-S. Se recolectaron variables epidemiológicas, clínicas y radiológicas. RESULTADOS: Se analizaron 51 casos y 102 controles. El análisis bivariado determinó como factores con p 51 años (OR: 0,17, IC95%: 0,05-0,51), uso de drogas (OR:2,5, IC95%: 1,1-5,4), antecedente de TB (OR: 20, IC95%: 8,4-47), reclusión previa (OR: 8, IC95%: 2,7-23,8), infección por VIH (OR: 0,2, IC95%: 0,08-1) y uso previo de fármacos antituberculosos (OR: 21, IC95%: 8,8-50). El análisis de regresión logística identificó como factores asociados a TB-PRE XDR al contacto de TB, antecedente de TB, tiempo de enfermedad y uso previo de fármacos antituberculosos. CONCLUSIÓN: Las medidas para limitar el desarrollo de TB-PRE XDR en pacientes con TB-S deben incidir sobre el antecedente de TB, contacto con TB, tiempo de enfermedad y uso previo de anti-TB no controlados; sin embargo, existen resultados no concluyentes sobre el hábito nocivo y la comorbilidad, siendo necesario más estudios para determinar su influencia como factores asociados identificables.


BACKGROUND: Resistance to anti-TB drugs is influenced by personal characteristics and health conditions in developing countries. AIM: To determine the factors associated with pre-extensively drug-resistant tuberculosis (PRE XDR-TB) at Hospital Nacional Dos de Mayo (HNDM) in patients between the 2017 and 2019. METHODS: An unpaired case control study was developed; defining as case PRE XDR-TB patient and as control S-TB patient. Epidemiological, clinical and radiological variables were collected. RESULTS: We analyzed 51 cases and 102 controls. The bivariate analysis showed as factors with p 51 years (OR: 0.17, 95% CI: 0.05-0.51), drug use (OR: 2.5, 95% CI: 1.1-5.4), previous history of TB (OR: 20, 95% CI: 8.4-47), previous confinement (OR: 8, 95% CI: 2.7-23.8), HIV infection (OR: 0.2, 95% CI: 0.08-1) and previous use of antiTB drugs (OR: 21, 95% CI: 8.8-50). The logistic regression analysis identified as associated factors with PRE XDR-TB the previous contact with TB, a history of TB, length of illness and previous use of tuberculosis antibiotics. CONCLUSION: The measures to limit the development of TB-PRE XDR in patients with TB-S must include the previous history of TB, TB contact, length of illness and previous use of uncontrolled antibiotics against TB; however, there are inconclusive results about the harmful habits and comorbidity, requiring more studies to determine their influence as identifiable associated factors.

ABSTRACT

INTRODUCCIÓN: Los pacientes hospitalizados con COVID-19 presentan un espectro clínico variable y su gravedad puede ser predicha por la presencia de factores de riesgo. OBJETIVO: Determinar los factores asociados al ingreso a UCI en pacientes internados por COVID-19 en Colombia. PACIENTES Y MÉTODOS: Estudio de cohorte multicéntrico, retrospectivo, en pacientes adultos hospitalizados por COVID-19 en Colombia, desde marzo de 2020 a enero de 2021. Se describieron las características de los pacientes y se establecieron predictores de ingreso a la UCI mediante un modelo de regresión logística. RESULTADOS: Se incluyeron 1.160 pacientes, edad media de 55 años, 59,7% fueron hombres y 426 pacientes (36,7%) ingresaron a UCI. Los factores asociados al ingreso a UCI fueron edad (OR 1,25; IC 95%: 1,14-1,37), sobrepeso (OR 2,82; IC 95%: 1,98-4,02) y obesidad (OR 2,97; IC 95%: 2,03-4,37), antecedente de cardiopatía valvular (OR 6,46; IC 95%: 1,84-27,48), hipotensión arterial al ingreso (OR 2,35; IC 95%: 1,40-3,97), SIRS (OR 2,03; IC 95%: 1,50-2,74), disnea (OR 1,52; IC 95%: 1,09-2.14), requerimiento de oxígeno (OR 2,64; IC 95%: 1,67-4,30), neutrofilia (OR1,09; IC 95%: 1,05-1,13), elevación de dímero D (OR 1,09; IC 95%: 1,03-1,18), compromiso multilobar (OR 2,19; IC 95%: 1,58-3,07) y consolidación pulmonar (OR1,52; IC 95%: 1,13-2,04). La mortalidad intrahospitalaria fue de 14,4% (166 pacientes), 2,3% entre los que no ingresaron a la UCI y 35,2% entre los que sí lo hicieron. CONCLUSIÓN: El 36,7% de pacientes hospitalizados por COVID-19 ingresó a UCI, identificándose predictores clínicos y de laboratorio asociados con este desenlace. La elaboración de modelos predictores con estos parámetros podría mejorar el pronóstico de los pacientes con COVID-19 que se hospitalizan.


BACKGROUND: Hospitalized patients with COVID-19 present a variable clinical spectrum and its severity might be predicted by the presence of risk factors. AIM: To determine the factors associated with ICU admission in patients hospitalized for COVID-19 in Colombia. METHOD: Retrospective multicenter cohort study, in adult patients hospitalized for COVID-19 in Colombia, from March 2020 to January 2021. Population characteristics were described and ICU admission predictors were established using a logistic regression model. RESULTS: 1,160 patients were included, mean age 55 years, 59.7% were men and 426 patients (36.7%) were admitted to the ICU. The associated factors were age (OR 1.25, 95% CI: 1.14-1.37), overweight (OR 2.82, 95% CI: 1.98-4.02) and obesity (OR 2.97, 95% CI: 2.03-4.37), valvular heart disease (OR 6.46, 95% CI: 1.84-27.48) hypotension at admission (OR 2.35, 95% CI: 1.40-3, 97), SIRS (OR 2.03, 95% CI: 1.50-2.74), dyspnea (OR 1.52, 95% CI: 1.09-2.14), oxygen requirement (OR 2.64, 95% CI: 1.67-4.30), neutrophilia (OR 1.09, 95% CI: 1.05-1.13), elevated D-dimer (OR 1.09, 95% CI: 1.03-1.18), multilobar lung involvement (OR 2.19, 95% CI: 1.58-3.07) and pulmonary consolidation (OR 1.52, 95% CI: 1.13-2.04). In-hospital mortality was 14.4% (166 patients), 2.3% among those that did not enter to the ICU and 35.2% among those who did. CONCLUSION: 36.7% of patients hospitalized for COVID-19 were admitted to the ICU. We identified clinical predictors associated with this outcome. Predictive models using these parameters could improve the prognostic of those patients with COVID-19 that are hospitalized.

ABSTRACT

SUMMARY: Stature estimation is one of the essential procedures for personal identification in forensic osteology. Therefore, the purposes of this study are to analyze the correlation between length and width of metatarsal measurements and stature, and to develop the regression equations for a Thai population. In this study, the samples were divided into two groups. The first group was called the "training group" for generating stature estimation equations, comprised of 200 skeletons, aged between 19-94 years. The second group was called the "test group" for evaluating the accuracy of generated equations, comprising 40 skeletons. The correlation between metatarsal parameters and stature were moderate to high, and all variables had positive significant correlation with stature. For males, the left ML2 is the length variable that showed the most correlation degree against stature (r=0.702), and the left MSW4 is the width variable that had the most correlation degree against stature (r=0.483). For females, right ML1 is the length variable that had the most correlation degree against stature (r=0.632), and right PW3 is the width stature that had the most correlation degree against stature (r=0.481). For all samples, left ML1 was the length variable that had the most correlation degree against stature (r=0.796) and right PW3 was the width variable that had the most correlation degree against stature (r=0.712). The results of generating multiple regression equations using a stepwise method reveals that the correlation coefficient (R) and standard error of estimate (SEE) were 0.761 and 4.96 cm, respectively, for males, and 0.752 and 4.93 cm for females, with 0.841 and 5.26 cm for all samples, respectively. According to these results, the mean of absolute error from the test group ranged from 3 to 5 cm. Therefore, stature estimation equations using length and width of metatarsals from our study can be applied to estimate stature in the Thai population.


La estimación de la estatura es uno de los procedimientos esenciales para la identificación personal en osteología forense. Por lo tanto, los propósitos de este estudio fueron analizar la correlación entre la longitud y el ancho de las medidas metatarsianas y la estatura, y desarrollar las ecuaciones de regresión para una población tailandesa. Las muestras se dividieron en dos grupos. El primer grupo se denominó "grupo de entrenamiento" para generar ecuaciones de estimación de estatura, compuesto por 200 esqueletos, con edades comprendidas entre los 19 y los 94 años. El segundo grupo se denominó "grupo de prueba" para evaluar la precisión de las ecuaciones generadas, que comprende 40 esqueletos. La correlación entre los parámetros metatarsianos y la estatura fue de moderada a alta, y todas las variables tuvieron una correlación significativa positiva con la estatura. Para el sexo masculino, la variable longitud ML2 izquierda es la que mayor grado de correlación presentó con la estatura (r=0,702), y la izquierda MSW4 fue la variable ancho la que mayor grado de correlación presentó con la estatura (r=0,483). Para el sexo femenino, ML1 derecho fue la variable longitud que tuvo mayor grado de correlación con la estatura (r=0,632), y PW3 derecha fue la variable ancho estatura que tuvo mayor grado de correlación con la estatura (r=0,481). Para todas las muestras, ML1 izquierdo fue la variable longitud que tuvo mayor grado de correlación con la estatura (r=0,796) y PW3 derecha fue la variable ancho que tuvo mayor grado de correlación con la estatura (r=0,712). Los resultados de generar ecuaciones de regresión múltiple usando un método paso a paso revela que el coeficiente de correlación (R) y el error estándar de estimación (SEE) fueron 0,761 y 4,96 cm, respectivamente, para los hombres y 0,752 y 4,93 cm para las mujeres, con 0,841 y 5,26 cm para todas las muestras, respectivamente. De acuerdo con estos resultados, la media del error absoluto del grupo de prueba osciló entre 3 y 5 cm. Por lo tanto, las ecuaciones de estimación de la estatura que utilizan la longitud y el ancho de los metatarsianos de nuestro estudio se pueden aplicar para estimar la estatura en la población tailandesa.

ABSTRACT

El objetivo del presente estudio fue determinar la relación entre la actividad física con el deterioro cognitivo en adultos mayores; esta investigación tiene un enfoque cuantitativo, de diseño no experimental, transversal, de tipo descriptivo y causal que llegó a evaluar a un total de 203 sujetos mediante el cuestionario de Pfeiffer (SPMSQ) y el cuestionario internacional de actividad física IPAQ. Con respecto a los resultados se encontró que, en la actividad física un 33.99% de los evaluados tienen actividad moderada, un 33% tiene actividad alta y un 21.67% tiene actividad baja; en el deterioro cognitivo un 71.43% no cuenta con deterioro, un 16.26% tiene un deterioro leve y un 12.32% tiene un deterioro moderado; en el análisis de regresión se determinó, a un nivel de confianza del 95%, que la actividad física se relaciona con el deterioro cognitivo (p=0.02, p<0.05). Finalmente, se llegó a la conclusión de que la actividad física si tiene relación con el deterioro cognitivo en los adultos mayores.


The aim of this study was to determine the relationship between physical activity and cognitive impairment in older adults. This research has a quantitative approach, non-experimental design, cross-sectional, descriptive and causal type that evaluated 203 subjects using the Pfeiffer Questionnaire (SPMSQ) and the International Physical Activity Questionnaire (IPAQ). Regarding physical activity, the results obtained show that 33.99% of those evaluated have moderate physical activity, 33% have high activity, and 21.67% have low activity levels. Besides, respecting cognitive impairment, 71.43% have no impairment, 16.26% have a mild impairment, and 12.32% have moderate impairment. In addition, in the regression analysis was determined, at a confidence level of 95%, that physical activity is related to cognitive impairment (p=0.02, p<0.05). Finally, it was concluded that physical activity is related to cognitive impairment in older adults.

ABSTRACT

INTRODUCCIÓN: La vacunación durante el embarazo ha demostrado ser una medida segura y efectiva que protege a la mujer gestante y al feto contra enfermedades inmunoprevenibles. OBJETIVO: Determinar los conocimientos, actitudes y prácticas de mujeres gestantes respecto a la vacunación en el marco de la pandemia por el virus SARS-CoV-2. MATERIALES Y MÉTODOS: Estudio observacional de corte transversal realizado en Instituciones Prestadoras de Servicios de Salud Públicas de los 19 municipios de Casanare, Colombia, entre enero y marzo de 2022. Los datos se recolectaron mediante un instrumento de medición documentado que incluyó 22 ítems agrupados en cuatro secciones: datos sociodemográficos, conocimiento, actitudes y prácticas sobre vacunación. RESULTADOS: La media de puntuación de conocimientos fue 5,9 (DE 1,9) de un máximo de 10. El 93,7% cree que la vacunación es realmente necesaria durante el embarazo. Los factores asociados al nivel adecuado de conocimiento incluyeron el grupo de edad entre 26-30 años (OR: 2,27; IC 95%: 1,21-4,25; p = 0,011), estar en el tercer trimestre de embarazo (OR: 2,37; IC 95%: 1,12-5,01; p = 0,024) y contar con un nivel educativo básico, medio o superior (OR: 10,45; IC 95%: 2,37-46,03; p = 0,002). CONCLUSIÓN: Es esencial fortalecer las estrategias de información, educación y comunicación, para promover la vacunación segura durante el embarazo.


BACKGROUND: Vaccination during pregnancy has proven to be a safe and effective measure that protects pregnant woman and the fetus against immuno-preventable diseases. AIM: To determine the knowledge, attitudes and practices of pregnant women regarding vaccination in the context of the SARS-CoV-2 pandemic.

Data were collected using a documented measurement instrument that included 22 items grouped into four sections: sociodemographic data, knowledge, attitudes and practices about vaccination. RESULTS: The mean knowledge score was 5.9 (SD: 1.9) of a maximun of 10; 93.7% believed that vaccination was really necessary during pregnancy. Factors associated with adequate level of knowledge included age group 26-30 years (OR: 2.27; 95% CI: 1.21-4.25; p = 0.011), being in the third trimester of pregnancy (OR: 2.37; 95% CI: 1.12-5.01; p = 0.024) and having basic, intermediate or higher education (OR: 10.45; 95% CI: 2.37-46.03; p = 0.002). CONCLUSIONS: It is essential to strengthen information, education and communication strategies to promote safe vaccination during pregnancy.
