Machine Learning Algorithms for Sex Classification by Using Variables of Orbital Structures: A Computed Tomography Study / Algoritmos de Aprendizaje Automático para la Clasificación del Sexo Mediante el Uso de Variables de Estructuras Orbitales: Un Estudio de Tomografía Computarizada

SUMMARY: Since machine learning algorithms give more reliable results, they have been used in the field of health in recent years. The orbital variables give very successful results in classifying sex correctly. This research has focused on sex determination using certain variables obtained from the orbital images of the computerized tomography (CT) by using machine learning algorithms (ML). In this study 12 variables determined on 600 orbital images of 300 individuals (150 men and 150 women) were tested with different ML. Decision tree (DT), K-Nearest Neighbour (KNN), Logistic Regression (LR), Random Forest (RF), Linear Discriminant Analysis (LDA), and Naive Bayes (NB) algorithms of ML were used for unsupervised learning. Statistical analyses of the variables were conducted with Minitab® 21.2 (64-bit) program. ACC rate of NB, DT, KNN, and LR algorithms was found as % 83 while the ACC rate of LDA and RFC algorithms was determined as % 85. According to Shap analysis, the variable with the highest degree of effect was found as BOW. The study has determined the sex with high accuracy at the ratios of 0.83 and 0.85 through using the variables of the orbital CT images, and the related morphometric data of the population under question was acquired, emphasizing the racial variation.

Dado que los algoritmos de aprendizaje automático dan resultados más fiables, en los últimos años han sido utilizados en el campo de la salud. Las variables orbitales dan resultados muy exitosos a la hora de clasificar correctamente el sexo. Esta investigación se ha centrado en la determinación del sexo utilizando determinadas variables obtenidas a partir de las imágenes orbitales de la tomografía computarizada (TC) mediante el uso de algoritmos de aprendizaje automático (AA). En este estudio se probaron 12 variables determinadas en 600 imágenes orbitales de 300 individuos (150 hombres y 150 mujeres) con diferentes AA. Se utilizaron algoritmos de AA de árbol de decisión (DT), K-Nearest Neighbour, regresión logística (RL), Random Forest (RF), análisis discriminante lineal (ADL) y Naive Bayes (NB) para el aprendizaje no supervisado. Los análisis estadísticos de las variables se realizaron con el programa Minitab® 21.2 (64 bits). La tasa de ACC de los algoritmos NB, DT, KNN y RL se encontró en % 83, mientras que la tasa de ACC de los algoritmos ADL y RFC se determinó en % 85. Según el análisis de Sharp, la variable con el mayor grado de efecto se encontró como BOW. El estudio determinó el sexo con alta precisión en las proporciones de 0,83 y 0,85 mediante el uso de las variables de las imágenes de TC orbitales, y se adquirieron los datos morfométricos relacionados de la población en cuestión, enfatizando la variación racial.

Impactos da COVID-19 aos acadêmicos de Odontologia no Brasil / Impactos del COVID-19 en estudiantes de Odontología en Brasil / Impact of COVID-19 on dental students in Brazil

O presente estudo teve por objetivo analisar os efeitos da pandemia da COVID-19 sobre o rendimento e aproveitamento acadêmico dos estudantes de Odontologia no Brasil. O estudo transversal descritivo foi realizado por meio da aplicação de questionário usando o aplicativo Google Forms, compartilhado via redes sociais como WhatsApp, Instagram, Facebook e endereços eletrônicos (e-mails) para 383 estudantes, número definido por cálculo amostral. Após a realização de estudo piloto, utilizou-se a técnica da "bola de neve virtual" para a coleta das respostas. Realizou-se análise descritiva e inferencial dos dados por meio de frequências e regressões logísticas multinominais com nível de significância de 5%. A maioria dos estudantes (72%) eram do sexo feminino, 81,5%oriundos de instituições privadas. Houve insatisfação tanto para com as aulas remotas (42,1% totalmente e 25,4% parcialmente) quanto para a formação acadêmica (44,1% totalmente e 25,6% parcialmente), relatou-se queda de rendimento em 70,7% dos estudantes e pensamento em abandonar os estudos (40,5% afirmam que sim e 10,2% relatam "talvez"). Região de residência e dispositivo utilizado para acompanhar as aulas influenciaram no pensamento em desistir dos estudos (p<0,05 e p=0,031 respectivamente), assim como o nível de conhecimento em informática influenciou no rendimento acadêmico durante a pandemia (p=0,009). Conclui-se que houve queda no rendimento acadêmico dos alunos durante a pandemia. O despreparo dos estudantes frente ao modelo remoto e as dificuldadesrelacionadas à aprendizagem demonstram que o Ensino Remoto Emergencial não foi suficiente para contemplar a gama de habilidades a serem desenvolvidas durante a formação (AU).

Hubo insatisfacción tanto con las clases remotas (42,1% total y 25,4% parcialmente) como con la formación académica (44,1% total y 25,6% parcial), reportándose una caída en el rendimiento del70,7% de los estudiantes que pensaron en abandonar sus estudios (40,5% dijo sí y el 10,2% dijo "tal vez"). La región de residencia y el dispositivo utilizado para seguir clases influyeron en el pensamiento de abandonar los estudios (p<0,05 y p=0,031 respectivamente), así como el nivel de conocimientos de informática influyó en el rendimiento académico durante la pandemia (p=0,009). Se concluye que hubo una caída en el rendimiento académico de los estudiantes durante la pandemia. La falta de preparación de los estudiantes para el modelo remoto y las dificultades relacionadas con el aprendizaje demuestran que la Educación Remota de Emergencia no fue suficiente para cubrir el conjunto de habilidades a desarrollar durante la formación (AU).

The aim of the present study was to analyze the effects of the COVID-19 pandemic on the academic performance of dental students in Brazil. A descriptive cross-sectional study was conducted using a questionnaire available on the Google Forms application andshared via social networks, such as WhatsApp, Instagram and Facebook, as well as electronic addresses (e-mails) to 383 students. This number was defined by the sample size calculation. After conducting a pilot study, the "virtual snowball" technique was used to collect responses. Descriptive and inferential analyses of the data were performed using frequencies and multinomial logistic regression, with a 5% significance level. Most students (72%) were female and studied at private dental schools (81.5%). Dissatisfaction was found for both remote classes (42.1% completely and 25.4% partially) and academic training (44.1% completely and 25.6% partially), with a reported drop in performance among 70.7% of the students and thoughts of abandoning their studies (40.5% answered "yes" and 10.2% answered "maybe"). Region of residence and device used to follow classes exerted an influence on thoughts of abandoning studies (p <0.05 and p = 0.031, respectively). Moreover, the level of computer knowledge exerted an influence on academic performance during the pandemic (p = 0.009). In conclusion, a drop in academic performance occurred among dental students during the pandemic. The lack of preparedness for the remote model and difficulties related to learning demonstrate that "Emergency Remote Education" was insufficient to cover the range of skills to be developed during training (AU).

Evaluation par régression logistique binaire de déterminants de la mortalité néonatale dans la province du Kongo Central / Evaluation by binary logistic regression of determinants of neonatal mortality in the Kongo Central province]

Neonatal mortality disturbs the whole of humanity. Its frequency remains very high throughout the world, but more so in developing countries. The DRC is ranked among the countries with the highest number of neonatal deaths in the world with the ratio of 47 per 1000 live births, (Kalonji DC et al 2018). Indeed, the province of Kongo Central has not remained indifferent to this health problem. With a view to improving newborn health during the neonatal period, the present study is conducted and envisages identifying the determinants of neonatal mortality in Kongo Central Province. For this study, the general population consisted of all newborns in the Province of Kongo Central from 2021 to 2022. A random sample of 117 cases met the inclusion criteria, of which we matched 1 case to 2 controls. After data analysis, we found the following results: the overall neonatal mortality rate was 333 per thousand live births. The logistic regression model identified the following determinants of neonatal mortality: age (OR= 1.16562 IC95 [1.035635 -1.3163]. p=0.0105), age less than 2 years (OR= 2.01966 IC95 [1.021601-4.058]. p=0.0449) and acute fetal distress (OR=2.62027IC95 [1.179464-5.878]. p=0.0181). In order to improve neonatal health, pregnant women should be made aware of the importance of prenatal consultations for early detection and appropriate management of high-risk pregnancies. They should be present at the onset of labor and give birth in the presence of qualified personnel

La mortalité néonatale dérange l'humanité toute entière. Sa fréquence demeure très élevée dans le monde entier mais plus dans les pays en développement. La RDC est classée parmi les pays ayant le plus grand nombre de décès néonatals dans le monde avec le ratio de 47 pour 1000 naissances vivantes. En effet, la province de Kongo Central n'est pas restée indifférente face à problème de santé. En vue d'améliorer la santé du nouveau-né pendant la période néonatale, la présente étude est menée et envisage d'identifier les déterminants de la mortalité néonatale dans la Province du Kongo Central. Pour cette étude, la population générale était constituée de tous les nouveau-nés de la Province du Kongo Central de 2021 à 2022. Les cas qui répondaient à ces critères d'inclusion étaient au nombre de 117 pris de façon aléatoire dont nous apparié 1 cas pour 2 témoins. Après analyse des données, nous avons trouvé les résultats suivant : le taux de la mortalité néonatale globale est de 333 pour mille naissances vivantes. Le modèle de la régression logistique a identifié les déterminants de la mortalité néonatale suivants ; l'âge (OR= 1,16562 IC95 [1,035635 -1,3163]. p=0,0105), l'intervalle de moins de 2 ans (OR= 2,01966 IC95 [1,021601-4,058]. p=0.0449) ainsi que, la souffrance fœtale aigue (OR=2,62027IC95 [1,179464-5,878]. p=0.0181). En vue d'améliorer la santé néonatale, il convient de sensibiliser les femmes enceintes sur l'importance des consultations prénatales pour un dépistage précoce et une prise en charge adéquate des grossesses à risque, se présenter dès le début du travail d'accouchement et d'accoucher en présence d'un personnel qualifié.

Prevalence of Oral Lesions Diagnosed at a Pathology Institute: A Four-year Analysis

Abstract Objective: To identify the most prevalent oral lesions based on reports from a pathology institute's reports and associations between malignant and oral potentially malignant disorders with patient's demographic variables and the anatomical location. Material and Methods: All 1,298 histopathological reports of oral lesions recorded in the database were reviewed. Demographic variables, anatomical location of the lesion, histopathological diagnosis of the lesions, and their biological behavior were analyzed. Results: Regarding the biological behavior of the identified lesions, benign lesions were predominant (70%), followed by lesions of undetermined behavior (14.3%), malignant lesions (14.2%), absence of histological alteration (1.2%), and finally, oral potentially malignant disorders (0.5%). The anatomical locations of the most prevalent oral lesions potentially malignant disorders and malignant were in the following structures of the oral cavity: gums, buccal mucosa, floor of the mouth and hard palate (p=49.2%), and tongue (p=48.7%). Conclusion: The probability of malignant and premalignant lesions was higher among males (PR= 4.21; 95% CI 2.08-6.22), the increase in age (PR = 1.06; 95% CI 1.05-1.08), and in the tongue region (PR = 5.48; 95% CI 1.67; 17.92). Identification of malignant and potentially malignant oral conditions is higher in older men and in tongue specimens.

Maternal Education Level as a Risk Factor for Early Childhood Caries / Maternal Education Level as a Risk Factor for Early Childhood Caries

ABSTRACT Objective: To determine the prevalence and risk factors associated with dental caries in Brazilian preschool children aged 2 to 5 years. Material and Methods: The following independent variables were evaluated: dental caries, dental trauma, and malocclusions. Data were analyzed using the Mann-Whitney test and Poisson regression (p<0.05). Results: The prevalence of dental caries in preschoolers was 55.1%. Child age, family income, maternal education, and tooth color alteration from trauma were significantly associated with dental caries (p<0.05). The final adjusted multivariate model showed a significant association between maternal education and dental caries; children of mothers with low education were 1.89 times more likely to have caries (PR: 1.89; 95%CI: 1.40-2.55) (p<0.01). Children with tooth color change from trauma were more likely to have dental caries (PR: 1.69; 95%CI: 1.22-2.34 (p=0.001). Conclusion: Child age, family income, maternal education, tooth discoloration and discoloration color are risk factors for the development of caries disease in children. Also, children of mothers with low educational levels have a higher chance of developing dental caries.

Did Perceived Stress Influence Possible Sleep Bruxism and Awake Bruxism in Dentistry Students During COVID-19 Pandemic? A Web-Based Cross-Sectional Study

ABSTRACT Objective: To assess the influence of perceived stress during the COVID-19 pandemic over awake bruxism (AB) and sleep bruxism (SB). Material and Methods: Observational web-based research carried out in a state in the Brazilian Northeast. The sample was composed of dental students from seven faculties, divided into three groups: beginning (1-4 semesters), middle (5-7), and end (8-10). An online questionnaire was constructed: Socio-demographic, Perceived Stress Scale (PSS-10), Self-reported AB and SB, and COVID-19 Fear Scale. Data were collected from April to June 2021 by sending the questionnaire through WhatsApp®, e-mail, and Instagram®. After bivariate analyses, a multiple logistic regression model was performed to discriminate variables for perceived stress and AB and SB. Hosmer and Lemeshow and chi-square tests were used to check the model's goodness of fit. Results: A total of 391 dental students participated in this research - most women (69.8%), unmarried (69.8%), family income less than three minimum wages (60.9%), self-reported physical activity (63.3%). Perceived stress was low to moderate (72.1%), SB was 39.6%, AB was 49.6%, and low COVID-19 fear was 81.1%. COVID-19 fear (3.03), being female (2.47), and using psychotropic (2.53) increases the chance of being stressed. Perceived stress can predict AB in models 1 (p=0.008) and 4 (p=0.039). There was no significance for perceived stress and SB. Conclusion: Perceived stress during the COVID-19 pandemic influenced awake bruxism.

Veintidós de cada 100 estudiantes de Odontología reportaron haberse sentido con ansiedad por la pandemia del COVID-19 durante al menos ocho días de las últimas dos semanas; la percepción de riesgo (OR = 2,46, IC95 por ciento 1,75 - 3,48) y el ser mujer (OR = 2,23, IC95 por ciento 1,33 - 3,76) incrementaron las probabilidades de ansiedad. Mientras que la autoeficacia (OR = 0,71, IC95 por ciento 0,51 - 0,99) y el antecedente de capacitación en COVID-19 (RM = 0,63, IC95 por ciento 0,4 - 0,99) las disminuyeron. Conclusiones: La alta percepción de riesgo y ser del sexo femenino se asocia con un aumento significativo de la ansiedad ante el COVID-19(AU)

Introduction: Containment measures by COVID-19 affect lifestyle and social relationships and it is reasonable to expect psychological effects from the thought of becoming infected. In dental practice, psychological reactions have been diverse. Objective: To identify anxiety and risk perception due to the COVID-19 pandemic, as well as the self-efficacy of dental students to take preventive measures. Methods: Cross-sectional study in students of the School of Dentistry of a public university in northeastern Mexico in May 2020 (n = 412). Online data were collected on anxiety, risk perception and self-efficacy on Likert scale and sociodemographic profile. Descriptive statistics and binary logistic regression multivariate analysis were used. Results: Mean age was 21.8 ± 2.8 years; 72.1 percent were female. Twenty-two out of 100 dental students reported feeling anxious about the COVID-19 pandemic for at least eight days in the last two weeks; risk perception (OR = 2.46, 95 percentCI 1.75 - 3.48) and being female (OR = 2.23, 95 percentCI 1.33-3.76) increased the odds of anxiety. While self-efficacy (OR = 0.71, CI95 percent 0.51 - 0.99) and history of COVID-19 training (OR = 0.63, CI95 percent 0.4-0.99) decreased them. Conclusions: High risk perception and being of the female sex are associated with a significant increase in COVID-19 anxiety(AU)

Aesthetic Dentistry - What You Decided and What I Want: Shade Selection

ABSTRACT Objective: To assess the relationship between patients' and dentists' perceptions of shade selection and its impact on satisfaction with the prosthesis. Material and Methods: A single group pre-post study was conducted at the Prosthodontics department of a teaching hospital in India. One hundred ten participants were selected through a systematic random sampling technique with inclusion and exclusion criteria. Patients' attitudes regarding the aesthetics of their maxillary anterior teeth were recorded using a validated questionnaire. Shades for the intended prosthetic crown selected by the dentist and chosen by the patient were recorded separately, and patient satisfaction with the appearance of the final prosthesis was recorded. We used descriptive statistics followed by Pearson's Chi-square test and a binomial logistic regression model for inferential statistics. Results: 109 participant's data were available for final analysis. Patients choose lighter shades than the dentist's selection, which is statistically significant (p=0.000). 73.4% were satisfied with the final prosthesis, and the binomial logistic regression model identified using patient-selected shade for the final prosthesis was significantly associated with patients' satisfaction with the final prosthesis (OR=3.3, p=0.001). Conclusion: The patient's preference should be considered with the dentist's option when selecting a shade to create good esthetics.

Análisis de edad, sexo y autopercepción de memoria en el deterioro cognitivo en la adultez mayor / Cognitive Impairment Among Older Adults in Chile: Evidence from the National Health Survey (ENS 2016-2017)

OBJETIVO: Análisis del deterioro cognitivo en personas mayores por edad, sexo y autopercepción de la memoria utilizando la Encuesta Nacional de Salud (ENS 2016-2017). MATERIAL Y MÉTODO: Estudio transversal analítico. Los datos provienen de la Encuesta Nacional de Salud (ENS 2016-2017). Se incluyen un n = 2.030 adultos mayores a 60 años. Se consideraron variables edad, sexo, autopercepción de la memoria y capacidad cognitiva medida con Test "Mini-Mental". Se realizó una correlación de Pearson entre los resultados del Mini-Mental y la edad por sexo y por nivel de autopercepción de la memoria y correlación de Spearman entre edad y nivel de autopercepción. Un análisis de Regresión Logística consideró, variable binaria por sospecha de deterioro cognitivo (DC) y predictoras, edad, nivel de autopercepción de la memoria y sexo. RESULTADOS: La evaluación fue completada por el 63.69% (n = 1.293) mujeres y 36,31% (n = 737) hombres. La edad promedio fue de 71,02 ± 7,9 años. La edad fue significativamente mayor en el grupo que presenta sospecha DC (p = 0,00). Mientras que la Edad y la Autopercepción negativa de manera independiente aumenta el riesgo de DC (OR = 1,1027 CI95%; 1,0392-1,1719 y OR = 1,4974 CI 95%; 0,4091-5,5725) respectivamente. CONCLUSIÓN: Un porcentaje importante de adultos mayores reportaron una memoria regular a mala (autopercibida). La edad fue la variable más significativa con relación a la sospecha de DC. Es decir que a mayor edad mayor deterioro cognitivo sin diferencia significativas por sexo. No obstante, las mujeres presentaron menos deterioro cognitivo.

OBJECTIVE: Analysis of cognitive impairment in the elderly by age, sex and self-perception of memory using the National Health Survey (ENS 2016-2017). MATERIAL AND METHOD: Analytical cross-sectional study. The data comes from the National Health Survey (ENS 2016-2017). A n = 2,030 adults over 60 years of age are included. Variables such as age, sex, self-perception of memory and cognitive ability measured with the "Mini-Mental" Test were considered. A Pearson correlation was made between the results of the Mini-Mental and age by sex and by level of self-perception of memory and Spearman's correlation between age and level of self-perception. A Logistic Regression analysis considered a binary variable due to suspicion of cognitive impairment (CD) and predictors, age, level of self-perception of memory, and sex. RESULTS: The evaluation was completed by 63.69% (n = 1,293) women and 36.31% (n = 737) men. The mean age was 71.02 ± 7.9 years. Age was significantly higher in the group with suspected DC (p=0.00). While Age and negative self-perception independently increase the risk of DC (OR= 1.1027 CI95%; 1.0392-1.1719 and OR = 1.4974 CI95%; 0.4091-5.5725) respectively. CONCLUSION: A significant percentage of older adults reported a fair to poor (self-perceived) memory. Age was the most significant variable in relation to the suspicion of CD. In other words, the older the age, the greater the cognitive deterioration without significant differences by sex. However, women presented less cognitive impairment.

SUMMARY: In the study, it was aimed to predict sex from hand measurements using machine learning algorithms (MLA). Measurements were made on MR images of 60 men and 60 women. Determined parameters; hand length (HL), palm length (PL), hand width (HW), wrist width (EBG), metacarpal I length (MIL), metacarpal I width (MIW), metacarpal II length (MIIL), metacarpal II width (MIIW), metacarpal III length (MIIL), metacarpal III width (MIIIW), metacarpal IV length (MIVL), metacarpal IV width (MIVW), metacarpal V length (MVL), metacarpal V width (MVW), phalanx I length (PILL), measured as phalanx II length (PIIL), phalanx III length (PIIL), phalanx IV length (PIVL), phalanx V length (PVL). In addition, the hand index (HI) was calculated. Logistic Regression (LR), Random Forest (RF), Linear Discriminant Analysis (LDA), K-nearest neighbour (KNN) and Naive Bayes (NB) were used as MLAs. In the study, the KNN algorithm's Accuracy, SEN, F1 and Specificity ratios were determined as 88 %. In this study using MLA, it is understood that the highest accuracy belongs to the KNN algorithm. Except for the hand's MIIW, MIIIW, MIVW, MVW, HI variables, other variables were statistically significant in terms of sex difference.

En el estudio, el objetivo era predecir el sexo a partir de mediciones manuales utilizando algoritmos de aprendizaje automático (MLA).

Parámetros determinados; longitud de la mano (HL), longitud de la palma (PL), ancho de la mano (HW), ancho de la muñeca (EBG), longitud del metacarpiano I (MIL), ancho del metacarpiano I (MIW), longitud del metacarpiano II (MIIL), ancho del metacarpiano II (MIIW), longitud del metacarpiano III (MIIL), ancho del metacarpiano III (MIIIW), longitud del metacarpiano IV (MIVL), ancho del metacarpiano IV (MIVW), longitud del metacarpiano V (MVL), ancho del metacarpiano V (MVW), longitud de la falange I (PILL), medido como longitud de la falange II (PIIL), longitud de la falange III (PIIL), longitud de la falange IV (PIVL), longitud de la falange V (PVL). Además, se calculó el índice de la mano (HI). Regresión logística (LR), Random Forest (RF), Análisis discriminante lineal (LDA), K-vecino más cercano (KNN) y Naive Bayes (NB) se utilizaron como MLA. En el estudio, las proporciones de precisión, SEN, F1 y especificidad del algoritmo KNN se determinaron en un 88 %. En este estudio que utiliza MLA, se entiende que la mayor precisión pertenece al algoritmo KNN. Excepto por las variables MIIW, MIIIW, MIVW, MVW, HI de la mano, otras variables fueron estadísticamente significativas en términos de diferencia de sexo.

Prevalence of apical periodontitis in people living with HIV in Southern Brazil / Prevalência de periodontite apical em pessoas vivendo com HIV no Sul do Brasil

Objective: This cross-sectional study aimed to describe the prevalence of apical periodontitis (AP) in people living with HIV (PLHIV) over 50 years old and explore its association with sociodemographic, medical, and oral characteristics. Methods: Data from 59 PLHIV were collected, and the periapical area of 1018 teeth was evaluated through periapical radiographs (Rx) using the periapical index (PAI). The presence and quality of root fillings and restorations (coronal fillings and crowns) were assessed with Rx, and caries presence was based on Rx and clinical data. Viral load (VL) and T CD4 counts were also analyzed. Results: AP prevailed in 71% of individuals and 8% of teeth. Family income of >5 Brazilian minimum wages (OR=0.06, 95% CI=0.005-0.62) and having at least one root-filled tooth (OR=14.55, 95% CI=1.45-145.72) were associated with AP prevalence, whereas VL and T CD4 were not. Caries, root filling, and restorations were associated with AP occurrence. Conclusion: PLHIV presented a high AP prevalence, but intrinsic factors related to HIV infection were not associated with AP in the studied subjects. PLHIV would benefit from oral health policies to prevent AP, as the results indicate that the endodontic disease in the present sub-population might be related to social problems.(AU)

Objetivo: este estudo transversal teve como objetivo descrever a prevalência de periodontite apical (PA) em pessoas vivendo com HIV (PVHIV) acima de 50 anos de idade, e explorar sua associação com características sociodemográficas, médicas e bucais. Métodos: os dados de 59 PVHIV foram coletados e a região periapical de 1018 dentes foi avaliada através de radiografias periapicais (Rx) usando o Índice Periapical (PAI). A presença e qualidade das obturações radiculares e restaurações (restaurações diretas e coroas) também foram avaliadas no Rx; a presença de cárie foi baseada em dados clínicos e radiográficos. Carga Viral (CV) e contagem de linfócitos T CD4 também foram avaliados. Resultados: a prevalência de PA nos indivíduos foi de 71%, e 8% dos dentes apresentaram PA. Renda familiar >5 salários mínimos (OR=0.06, 95% CI=0.005-0.62) e ter pelo menos um dente com obturação endodôntica (OR=14.55, 95% CI=1.45-145.72) foram associados com a prevalência de PA, enquanto que CV e T-CD4 não foram. A presença de cárie, obturação endodôntica e restaurações foram associadas com a presença de PA no dente. Conclusão: PVHIV apresentaram uma alta prevalência de PA, mas fatores intrínsecos relacionados à infecção pelo HIV não foram associados com PA nos sujeitos avaliados. PVHIV se beneficiariam de políticas públicas de saúde para prevenir a PA, uma vez que os resultados indicam que a doença endodôntica na presente subpopulação pode ser relacionada a problemas sociais.(AU)

Factores predictivos de rotura de aneurismas intracraneales / Rupture Predictive Factors for Intracranial Aneurysms

Introducción: Un aneurisma intracraneal roto provoca una hemorragia subaracnoidea. La enfermedad presenta una alta mortalidad y morbilidad. Sin embargo, no todos se rompen. Mejorar la predicción de rotura permitirá un tratamiento quirúrgico preventivo en un grupo de pacientes y evitará una intervención quirúrgica con riesgos en otro grupo de enfermos. Es necesario identificar factores predictivos para mejorar la estratificación del riesgo de rotura y optimizar el tratamiento de los aneurismas intracraneales incidentales. Objetivo: Identificar factores predictivos de rotura de aneurismas intracraneales. Métodos: En una muestra de 152 pacientes espirituanos con aneurismas intracraneales saculares rotos (n = 138) y no rotos (n = 22) y 160 imágenes de angiografía por tomografía computarizada, se realizaron mensuraciones de los índices o factores morfológicos, los cuales se combinaron mediante análisis de regresión logística con variables demográficas y clínicas. Resultados: El grupo de edad con mayor frecuencia de presentación de aneurismas fue el de mayor de 65 años. La muestra estuvo representada, en su gran mayoría, por el sexo femenino. Se identificaron tres factores clínicos y cuatro factores morfológicos estadísticamente significativos, asociados con la rotura. El índice de no esfericidad (p = 0,002 y el sexo femenino (p = 0,02) fueron los de mayor significación estadística. Conclusiones: Se detectaron siete factores predictivos de rotura de aneurismas intracraneales estadísticamente significativos, de los cuales el índice de no esfericidad resultó el de mayor significación(AU)

Introduction: A ruptured intracranial aneurysm causes a subarachnoid hemorrhage. The disease has high mortality and morbidity. However, not all of them break. Improving the rupture prediction will allow preventive surgical treatment in a group of patients and it will avoid risky surgical intervention in another group of patients. It is necessary to identify predictive factors to improve rupture risk stratification and to optimize treatment of incidental intracranial aneurysms. Objective: To identify rupture predictive factors for intracranial aneurysms. Methods: Measurements of the morphological indices or factors were performed in a sample of 152 patients from Sancti Spiritus with ruptured (n = 138) and unruptured (n = 22) saccular intracranial aneurysms and 160 computed tomography angiography images. They were combined using logistic regression analysis with demographic and clinical variables. Results: The age group with the highest frequency of aneurysm presentation was older than 65. The sample was represented, in its vast majority, by the female sex. Three clinical factors and four statistically significant morphological factors associated with rupture were identified. The non-sphericity index (p = 0.002) and the female sex (p = 0.02) were the most statistically significant. Conclusions: Seven statistically significant predictors of intracranial aneurysm rupture were detected, the non-sphericity index being the most significant(AU)
