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

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

SUMMARY: The foramen magnum is an important topographic opening which connects cranial cavity and spinal canal. The analysis of the bone material established that there are differences in the shape of the foramen magnum between individuals. The aim of this study was to determine sex based on shape and size of foramen magnum using geometric morphometrics method. A study was performed on three-dimensional models (3D models) of 214 human skulls of known sex and known age (141 male skulls and 73 female skulls). The skulls are located at the museum of Medical Faculty, University of Sarajevo. Skulls belong to Bosnian population from the mid-twentieth century. All examined skulls were scanned with a laser scanner to obtain their 3D models. On 3D models of the examined skulls, four landmarks were marked on foramen magnum. Analysis of sex determination was performed using the MorphoJ program. Results of this study showed that there are sex differences in the shape and size of the foramen magnum. Sex determination based on the shape and size of the foramen magnum was showed 65.25 % accuracy for male and 63.01 % accuracy for female using geometric morphometrics method. Examination of the effect of size of foramen magnum on sexual dimorphism of shape of foramen magnum showed a statistically significant effect. Sex determination based just on the shape of foramen magnum using geometric morphometrics method was possible with 62.41 % accuracy for male and 58.90 % accuracy for female on examined sample. Sex differences on shape and size of foramen magnum were found using geometric morphometrics method on three-dimensional models of the examined skulls. The percentage of accuracy was higher for male based on the shape and size of the foramen magnum than for female.


El foramen magno es una importante abertura topográfica que conecta la cavidad craneal y el canal espinal. El análisis del material óseo estableció que existen diferencias en la forma del foramen magno entre individuos. El objetivo de este estudio fue determinar el sexo en función de la forma y el tamaño del foramen magno utilizando morfometría geométrica. El estudio se realizó en modelos tridimensionales (modelos 3D) de 214 cráneos humanos de sexo y edad conocidos (141 cráneos masculinos y 73 cráneos femeninos). Los cráneos se encuentran en el museo de la Facultad de Medicina de la Universidad de Sarajevo. Los cráneos pertenecen a población bosnia de mediados del siglo XX. Todos los cráneos examinados fueron escaneados con un escáner láser para obtener sus modelos 3D. En los modelos 3D de los cráneos examinados, se marcaron cuatro puntos de referencia en el foramen magno. El análisis de determinación de sexo se realizó utilizando el programa MorphoJ. Los resultados de este estudio mostraron que existen diferencias de sexo en la forma y el tamaño del foramen magno. La determinación del sexo basada en la forma y el tamaño del foramen magno mostró una precisión del 65,25 % para los hombres y del 63,01 % para las mujeres utilizando morfometría geométrica. El examen del efecto del tamaño del foramen magno sobre el dimorfismo sexual de la forma del foramen magno mostró un efecto estadísticamente significativo. La determinación del sexo basada solo en la forma del foramen magno utilizando morfometría geométrica fue posible con una precisión del 62,41 % para los hombres y del 58,90 % para las mujeres en la muestra examinada. Se encontraron diferencias de sexo en la forma y el tamaño del foramen magno utilizando morfometría geométrica en modelos tridimensionales de los cráneos examinados. El porcentaje de precisión fue mayor para los hombres en función de la forma y el tamaño del foramen magno que para las mujeres.

ABSTRACT

Los objetivos del presente estudio fueron primero evaluar la asociación de dimensiones antropométricas de tórax y tronco con índices espirométricos, segundo, ajustar una ecuación de predicción con dimensiones antropométricas de tronco y tercero, comparar nuestro modelo predictivo con dos ecuaciones diagnósticas. Se evaluaron 59 estudiantes universitarios entre 20 y 40 años, de ambos sexos, sin hábito tabáquico. Las variables consideradas fueron: edad, sexo, peso, estatura, diámetro transverso de tórax, diámetro anteroposterior de tórax, perímetro de tórax, altura de tórax, altura de tronco, flujo espiratorio máximo (FEM), volumen espiratorio forzado en el primer segundo (VEF1) y capacidad vital forzada (CVF). Se utilizó el análisis de regresión múltiple para estimar los valores espirométricos en función de las variables demográficas y antropométricas. La CVF y el VEF1 tienen asociación lineal directa con el diámetro transverso de tórax, altura de tórax, perímetro de tórax y altura de tronco. Se ajustó una ecuación de regresión lineal múltiple que indicó que es posible estimar la CVF y el VEF11 en función de la altura de tronco y el perímetro de tórax para ambos sexos. Estas variables son capaces de explicar el 74 % de los valores de CVF y el 68 % de los valores de VEF1. Al comparar los valores obtenidos por nuestras ecuaciones predictivas con las ecuaciones de referencia nacional observamos que nuestros resultados son más cercanos a los de Quanjer et al. (2012) que a los de Knudson et al. (1983). La altura de tronco y el perímetro de tórax tienen asociación directa con el VEF1 y CVF y son buenos predictores del VEF1 y CVF en estudiantes universitarios. Nuestros valores estimados son más cercanos a las ecuaciones de Quanjer et al. (2012) en comparación a las estimaciones de Knudson (1983).


SUMMARY: The purposes of the present study were first to evaluate the association between anthropometric dimensions of the thorax and trunk with spirometric indices, second, to fit a prediction equation with anthropometric dimensions of the trunk, and third, to compare our predictive model with two diagnostic equations. Fifty-nine university students between 20 and 40 years old, of both sexes and non-smokers were recruited. Variables considered were age, sex, weight, height, chest transverse diameter, chest anteroposterior diameter, chest perimeter, chest height, trunk height, maximum expiratory flow (PEF), forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC). Multiple regression analysis was used to estimate spirometric values based on demographic and anthropometric variables. FVC and FEV1 have a direct linear association with chest transverse diameter, chest height, chest circumference, and trunk height. A multiple linear regression equation was fitted, indicating that it is possible to estimate FVC and FEV1 as a function of trunk height and chest girth for both sexes. These variables can explain 74% of the FVC values and 68% of the FEV1 values. Comparing the values obtained by our predictive equations with the national reference equations, we observe that our results are closer to those of Quanjer et al. (2012) than to those of Knudson et al. (1983). Trunk height and chest circumference have a direct association with FEV1 and FVC and are good predictors of FEV1 and FVC in university students. Our estimated values are closer to Quanjer et al. (2012) than Knudson et al. (1983) prediction equations.

ABSTRACT

SUMMARY: The aim of this study was twofold. The first aim was to examine the association of anthropometric measures on kinematic characteristic which represent stroke efficiency in young female front crawl swimmers. The second aim was to create a prediction model which could provide help to swimming coaches with the purpose of easier and better selection of female front crawl swimmers by measuring and following basic morphological characteristics. Eighty female competitive swimmers all members of the swimming Clubs in province of Vojvodina, Serbia (age 12.52 ± 08 years, years of training involvement 4.05 ± 1.2 and personal best times over 50 m front crawl 32.79 ± 0.86 s) performed 50 m front crawl race. The 50 m front crawl swimming efficiency expressed through stroke index significantly was related to body height (r = 0.44, p = 0.000), body mass (r = 0.402, p = 0.000), sitting height (r = 0.612, p = 0.000) arm spam (r = 0.576, p = 0.000), biacromial diameter (r = 0.470, p = 0.000), bicrestal diameter (r = 0.348, p = 0.001) and with chest circumference (r = 0.427, p = 0.000). Regression equation for stroke index prediction was defined by following variables: body mass, sitting height, arm span, chest circumference with 43.5% explained variance. Additionally by analyzing obtained model the higher the values of SH, ARSP, CHICR and the lower values of BM in a group of early pubescent female swimmers the higher 50 m front crawl efficiency values will be.


Este estudio tiene dos objetivos principales. El primer objetivo fue examinar la asociación de las medidas antropométricas con las características cinemáticas que representan la eficiencia de la brazada en nadadoras jóvenes estilo crol. El segundo objetivo era crear un modelo de predicción que pudiera ayudar a los entrenadores de natación con el propósito de seleccionar mejor y más fácilmente a las nadadoras crol midiendo y siguiendo las características morfológicas básicas. Ochenta nadadoras competitivas, todas miembros de los clubes de natación en la provincia de Vojvodina, Serbia (edad 12,52 ± 8 años, años de participación en el entrenamiento 4,05 ± 1,2 y mejores tiempos personales en 50 m estilo crol 32,79 ± 0,86 s) realizaron una carrera de 50 m estilo crol. La eficiencia de nado crol de 50 m expresada a través del índice de brazada se relacionó significativamente con la altura del cuerpo (r = 0,44, p = 0,000), la masa corporal (r = 0,402, p = 0,000), la altura sentado (r = 0,612, p = 0,000) y el brazo. spam (r = 0,576, p = 0,000), diámetro biacromial (r = 0,470, p = 0,000), diámetro bicrestal (r = 0,348, p = 0,001) y con perímetro torácico (r = 0,427, p = 0,000). La ecuación de regresión para la predicción del índice de brazada se definió mediante las siguientes variables: masa corporal, altura sentada, extensión de los miembros superiores, circunferencia del pecho con una varianza explicada del 43,5 %. Además, al analizar el modelo obtenido, cuanto más altos sean los valores de SH, ARSP, CHICR y los valores más bajos de BM en un grupo de nadadoras púberes tempranas, mayores serán los valores de eficiencia de crol de 50 m.

ABSTRACT

ABSTRACT Objective: To evaluate the characteristics and factors associated with the intake of ultra-processed cariogenic foods (UFC) by preschoolers during the COVID-19 pandemic. Material and Methods: This is a cross-sectional study involving parents of 672 children from two to five years old enrolled at public schools in Curitiba, Brazil. Parents answered a questionnaire about socioeconomic and demographic data, their behavior regarding the dietary education of their children (Parent Mealtime Action Scale - translated and validated for use in Brazil), and children's food intake (qualitative food frequency questionnaire - list of foods based on a report from the Pan American Health Organization). The data were analyzed using Poisson regression analysis (α=0.05). Results: About 43% of parents/guardians reported changes in their children's diet during the pandemic, being that diet got worse and better in 19% and 24% of the cases, respectively. The ultra-processed cariogenic foods with the highest daily intake frequencies were sweetened juices/sweetened drinks (0.52), followed by cookies (0.37), and candies (0.35). Parents with a lower level of education reported a daily frequency of UCF intake 1.36 times higher (PR=1.359; CI 95%: 1.106-1.669) in their children compared to those with a higher level of education. On the other hand, parents'/guardians' report of higher intake and greater offer of fruits and vegetables to children was associated with low UCF intake (PR=0.716; CI 95%: 0.592-0.866). Conclusion: The lower level of formal education of parents/guardians and lower availability of fruits and vegetables were related to higher consumption of ultra-processed cariogenic foods by children.

ABSTRACT

Este estudio evaluó la retención de conocimientos, de estudiantes de pregrado expuestos a una actividad educativa de detección de lesiones de caries. Estudiantes de Odontología de los últimos años fueron invitados a participar del estudio. Ellos recibieron la capacitación 1 año y medio antes. Para evaluar su retención de conocimientos se realizaron evaluaciones teóricas y prácticas para dimensionar los conocimientos, habilidades y actitudes de los estudiantes. Cada prueba se valoró entre 0 a 10. Análisis de regresión multinivel se usaron para ver la asociación entre el desempeño de los estudiantes y su percepción sobre la importancia de la actividad. Otras peculiaridades relacionadas al desempeño en temas específicos y diferentes tipos de evaluación también fueron estudiadas. 302 estudiantes fueron evaluados. En promedio, los estudiantes tuvieron una nota 6.68 para la teórica y 5.5 para la práctica, con desviación estándar de 1.88 y de 2.27, respectivamente. La percepción de los estudiantes sobre la actividad didáctica fue asociada a su desempeño. En la evaluación teórica, los estudiantes fueron peores al relacionar la condición clínica con la histológica (21% de aciertos) y al justificar su conducta frente a lesiones inactivas (36% de aciertos). En la evaluación práctica, el 70-90% de los estudiantes demostraron tener capacidad para detectar, valorar la actividad y tomar decisiones clínicas sobre lesiones iniciales y severas. Solo 50% detectó correctamente lesiones moderadas y 32% sabe su manejo. Concluimos que la retención de conocimientos de los alumnos en mediano plazo es moderada está dentro de lo esperado.


Este estudo avaliou a retenção de conhecimento, em médio prazo, de graduandos expostos a uma atividade educativa de detecção de cárie. Esta é uma parte do estudo multicêntrico IuSTC. Alunos dos últimos anos foram convidados a participar e passaram pela atividade. Foram avaliados quanto à retenção do conhecimento após 1,5 ano. Avaliações teóricas e práticas (pontuadas de 0 a 10) foram preparadas para avaliar conhecimento, habilidades e atitudes. Os escores foram definidos como desfechos. Análises de regressão multinível testaram a associação entre a performance dos alunos e sua percepção sobre a importância da atividade dentro do seu currículo. Particularidades relacionadas à performance em tópicos específicos e diferentes tipos de avaliação também foram explorados. 302 alunos participaram das avaliações. Em média, os alunos tiveram medias (desvio-padrão (DP), de 6,68 (1,88) teórica e 5,5 (2,27) prática. A percepção dos alunos esteve associada com sua performance. Na avaliação teórica, os alunos tiveram pior performance ao relacionar a condição clínica com a histológica (21% de acertos) ou em justificar a conduta frente a lesões inativas (36% de acertos). Na avaliação prática, 70-90% dos alunos demonstraram habilidade de detectar, avaliar atividade e tomar decisões clínicas frente a lesões iniciais e severas, enquanto 50% avaliaram adequadamente as lesões moderadas e apenas 32% demonstrou atitude correta do manejo. Em conclusão, a retenção do conhecimento dos alunos está dentro do esperado em uma análise de médio prazo. Para alguns tópicos (por exemplo, relacionados a prática e justificativa de atitudes), a performance dos alunos tende a ser pior.


This study aimed to evaluate undergraduate students' medium-term knowledge retention after a learning activity related to caries lesions detection. This study is part of the IuSTC multicenter study. Last-years dental students were invited to participate and were exposed to the teaching activity. Their knowledge retention after 1.5 year was assessed. Theoretical and practical tests (scored 0 to 10) were prepared to evaluate knowledge, abilities and attitudes The scores were set as outcomes. Multilevel regression analyses were used to assess the association between students' performance and his/her perception about the importance of such learning activity in curriculum. Particularities related to students' performance in specific topics and types of evaluations were also explored. 302 students participated. On average, students achieved 6.68 (SD=1.88) in theoretical and 5.5 (SD=2.27) in practical assessment. Student's perception was associated with their performance. In theoretical test, students performed worse (21% of correct answers) in linking clinical and histological condition or justifying clinical decision-making for inactive lesions (36% of correct answers). In the practical test, 70-90% demonstrated ability to detect, assess activity and make the decision about management of initial or severe lesions, while 50% of students could assess adequately moderate caries lesions and only 32% demonstrated correct attitude related to their management. Undergraduate students' knowledge retention related to the detection of caries lesions is moderate in a medium-term analysis. It is noted that for some topics (e.g. not related to practice/justification of attitudes), the students' performance tends to be worse.

ABSTRACT

ABSTRACT Objective: To analyze the transversal and anterior-posterior changes obtained in patients treated only with the Damon system. Material and Methods: 51 patients with either class I or class II division 1 sagittal relationship treated with the Damon system and the same archwire sequence were retrospectively selected. Dental casts of each patient before (T0) and after treatment (T1) were scanned and analyzed using NEMOCAST 3D software. Inter-molar, inter first-premolar, inter-second premolar and inter-canine distances were measured in both upper and lower arches. Initial and final lateral cephalograms were traced using the OrisCeph program. Pre and post-treatment measurements were compared using the t-test for repeated measurements. The Pearson Correlation Index and Linear Regression Analysis were used to determine the dependence between continuous variables. The significance level was set at 0.05. Results: Transversal diameters in the upper arch increase statistically significantly, especially in the bicuspid area. Initial intra-arch diameter was the only statistically significant variable correlated with the final expansion obtained. A linear negative correlation between the initial latero-posterior torque and the final expansion was observed in both arches. Conclusion: Using identical arches in patients with very different initial characteristics, the changes in bicuspids' diameters remain the most predominant. Patients with initial more negative torque in the posterior region had a higher expansion amount.

ABSTRACT

ABSTRACT Objective: To describe oral healthcare services administered during the lockdown in the Eastern Mediterranean region and to investigate the role of socio-professional characteristics of dental practitioners or their self-reported COVID-19 infection. Material and Methods: A questionnaire was distributed to dental practitioners in all healthcare sectors in Jordan, Egypt, and Saudi Arabia. Results: There was a total of 335 participants, with the majority being females (N=225, 67.2%) and general practitioners (N=202, 60.3%). Cellulitis was the most common emergency encountered (N=108). The most common urgent procedures were for pulpitis, abscesses, and pericoronitis (N=191, 130, and 95, respectively). Country-specific significant associations were pulpitis in Egypt and Jordan, broken symptomatic teeth in Jordan, and biopsy in Egypt (p<0.05). The Ministry of Health was significantly associated with the management of dental infections, avulsion, and orthodontic emergencies, while university hospitals were significantly associated with advanced restorative procedures (p<0.05). Male practitioners performed significantly more procedures, particularly surgical emergencies (p<0.05). Conclusion: Dental infections were the most common complaints among dental patients during lockdown. Countryand sector-specific dental procedures are detected. Male gender seems to play a determinant role in performing a higher number of procedures, particularly for surgical emergencies (AU).

ABSTRACT

Contexte et objectif. Les rayonnements ultra-violets constituent un facteur connu de risque de carcinome photo-induit chez l'albinos en milieu à fort ensoleillement. La présente étude a évalué l'ampleur du carcinome photo induit et a recherché les principaux déterminants chez les sujets de phototype albinos à Kinshasa. Méthodes. Dans une étude transversale, des sujets de phototype albinos recrutés de manière consécutive, ont été examinés du 1er janvier 2020 au 30 septembre 2020 au Service de dermatologie des Cliniques Universitaires de Kinshasa. La fréquence du carcinome a été estimée et ses déterminants recherchés à l'aide d'une analyse de régression logistique. Résultats. Au total 100 albinos ont été inclus. Près d'un albinos sur deux (44 %) a développé un carcinome. En analyse multivariée, l'âge >30 ans (OR : 2,68 ; IC 95% :1,65-11,10 ; p=0,017), la présence des kératoses actiniques (OR: 3.80; IC 95%: 1.43-7.23; p=0.023), un antécédent familial de cancer non cutané (OR : 2,40 ; IC95% : 1,47-12,35 ; p=0,29), un antécédent familial de carcinome (OR : 4,99 ; IC95% :3,0-9,29 ;p=0,000) et un antécédent personnel de polytransfusion (OR :2,30 ; IC 95% :1,26-6,20 ;p=0,045) ont été identifiés comme les principaux déterminants du carcinome photo-induit. Conclusion. Près d'un albinos sur deux présente un carcinome photo-induit. Ceci justifie l'intensification des mesures comportementales et préventives contre le développement des cancers cutanés ciblant particulièrement les albinos âgés de moins de 30 ans, présentant des kératoses actiniques et ceux avec antécédents familiaux de cancer (carcinome et autres).

ABSTRACT

Body mass index (BMI) has been increasing globally in recent decades. Previous studies reported that BMI was associated with sex hormone levels, but the results were generated via linear regression or logistic regression, which would lose part of information. Quantile regression analysis can maximize the use of variable information. Our study compared the associations among different regression models. The participants were recruited from the Center of Reproductive Medicine, The First Hospital of Jilin University (Changchun, China) between June 2018 and June 2019. We used linear, logistic, and quantile regression models to calculate the associations between sex hormone levels and BMI. In total, 448 men were included in this study. The average BMI was 25.7 (standard deviation [s.d.]: 3.7) kg m-2; 29.7% (n = 133) of the participants were normal weight, 45.3% (n = 203) of the participants were overweight, and 23.4% (n = 105) of the participants were obese. The levels of testosterone and estradiol significantly differed among BMI groups (all P < 0.05). In linear regression and logistic regression, BMI was associated with testosterone and estradiol levels (both P < 0.05). In quantile regression, BMI was negatively associated with testosterone levels in all quantiles after adjustment for age (all P < 0.05). BMI was positively associated with estradiol levels in most quantiles (≤80th) after adjustment for age (all P < 0.05). Our study suggested that BMI was one of the influencing factors of testosterone and estradiol. Of note, the quantile regression showed that BMI was associated with estradiol only up to the 80th percentile of estradiol.

ABSTRACT

Objective: To investigate the current situation of job involvement of nurses in military hospitals in Henan Province and analyze the influencing factors, so as to provide reference for improving the level of job involvement of military nurses. Methods: In February 2022, the employed nurses of 4 military hospitals in Henan Province were investigated by convenient sampling method. A total of 663 questionnaires were collected, including 632 valid questionnaires, with an effective recovery rate of 95.32%. The self-designed questionnaire was used to investigate the basic information of nurses, the Job Involvement Scale was used to investigate the job involvement of nurses, the Emotional Labor Scale for Nurses was used to investigate nurses' emotions, and the Work-Family Conflict Scale was used to investigate the work-family conflict of nurses. Independent sample t-test and univariate analysis of variance were used to compare the job involvement of military employed nurses with different demographic characteristics, Pearson correlation analysis was used to explore the correlation between emotional labor, work-family conflict and job involvement, and hierarchical regression analysis was used to explore the impact of relevant variables on the job involvement of military employed nurses. Results: The total average score of job involvement of military employed nurses was (3.68±1.13), and the scores of vitality, dedication and focus were (3.64±1.15), (3.74±1.25) and (3.67±1.21) respectively. The total score of emotional labor of nurses was 33-80 (62.95±8.12), with an average score of (3.93±0.51). The total score of work-family conflict was 18-94 (55.16±13.53), with an average score of (3.06±0.75). Professional emotional regulation, patient-centered emotional inhibition and standardized emotional play were positively related to the job involvement (r=0.46, 0.41, 0.22, P<0.01). Time-based conflict, stress-based conflict and behavior-based conflict had negative correlation with the job involvement (r=-0.12, -0.23, -0.20, P<0.01). In hierarchical regression analysis, after controlling demographic variables, emotional labor and work-family conflict accounted for 17.2% and 4.2% of the variation of job involvement. Conclusion: The job involvement of military employed nurses tends to be at a moderate level. Emotional labor and work-family conflict can significantly affect their job involvement.

ABSTRACT

Multicollinearity is an important issue affecting the results of regression analysis. LASSO developed in recent years has great advantages in selecting explanatory variables, processing high-dimensional data, and solving multicollinearity problems. This method adds a penalty term to the model estimation, which can compress the regression coefficients of some unnecessary variables to zero and then remove them from the model to achieve the purpose of variable screening. This paper focuses on the LASSO method and compares it with optimal subsets, ridge regression, adaptive LASSO, and elastic net results. It is found that both LASSO and adaptive LASSO have good performance in solving independent variable multicollinearity problems and enhancing model interpretation and prediction accuracy.

ABSTRACT

Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that have been found in different food categories, and meat products can have high concentrations of PAHs, since the technological processes to which they are subjected, such as smoking, can produce several compounds. Considering the risk that these compounds can bring to the population's health, it is essential to develop an accurate and reliable method to evaluate the contamination of PAHs in products of animal origin. The objective of this study was to optimize and validate a method for the quantification of 4 PAHs (benz[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene) in salami. The methodology included saponification, liquid­liquid extraction, solid-phase purification, and quantification by ultra-high-performance liquid chromatography. The effects of saponification parameters were investigated by experimental design, whereas the model obtained by regression analysis was considered satisfactory with the dissolution solvent of potassium hydroxide providing the highest global sum of areas. In validation, the parameters studied were adequate and within European and INMETRO Guidelines limits. The evaluation of 22 samples indicated that 27% were contaminated with at least one of the 4 PAHs, and benz[a]anthracene being the prevalent one with content varying between < 1.00 and 17.58 µg/kg. Two samples showed PAHs contamination above the maximum tolerable limit in the European Commission Regulation.

ABSTRACT

OBJECTIVE@#To describe the secular trends of age at menarche and age at natural menopause of women from a county of Shandong Province.@*METHODS@#Based on the data of the Premarital Medical Examination and the Cervical Cancer and Breast Cancer Screening of the county, the secular trends of age at menarche in women born in 1951 to 1998 and age at menopause in women born in 1951 to 1975 were studied. Joinpoint regression was used to identify potential inflection points regarding the trend of age at menarche. Average hazard ratios (AHR) of early menopause among women born in different generations were estimated by performing multivariate weighted Cox regression.@*RESULTS@#The average age at menarche was (16.43±1.89) years for women born in 1951 and (13.99±1.22) years for women born in 1998. The average age at menarche was lower for urban women than that for rural women, and the higher the education level, the lower the average age at menarche. Joinpoint regression analysis identified three inflection points: 1959, 1973 and 1993. The average age at menarche decreased annually by 0.03 (P < 0.001), 0.08 (P < 0.001), and 0.03 (P < 0.001) years respectively for women born during 1951-1959, 1960-1973, and 1974-1993, while it remained stable for those born during 1994-1998 (P=0.968). As for age at menopause, compared with women born during 1951-1960, those born during 1961-1965, 1966-1970 and 1971-1975 showed a gradual decrease in the risk of early menopause and a tendency to delay the age at menopause. The stratified analysis presented that the risk of early menopause gradually decreased and the age of menopause showed a significant delay among those with education level of junior high school and below, but this trend was not obvious among those with education level of senior high school and above, where the risk of early menopause decreased and then increased among those with education level of college and above, and the corresponding AHRs were 0.90 (0.66-1.22), 1.07 (0.79-1.44) and 1.14 (0.79-1.66).@*CONCLUSION@#The age at menarche for women born since 1951 gradually declined until 1994 and leveled off, with a decrease of nearly 2.5 years in these years. The age at menopause for women born between 1951 and 1975 was generally delayed over time, but the trend of first increase and then decrease was observed among those with relatively higher education levels. In the context of the increasing delay in age at marriage and childbearing and the decline of fertility, this study highlights the necessity of the assessment and monitoring of women' s basic reproductive health status, especially the risk of early menopause.

ABSTRACT

This study analyzed the structure of social representations of an authoritarian regime in Brazil (Military Regime, 1964-1985), the variables associated with reporting different emotions about that past, and support for authoritarian solutions in the present. A sample of 200 participants aged 18 to 85 years (M = 31.54; SD = 13.84) responded to a free word association task in which they indicated three words that came to mind about the Military Regime. A prototypical analysis showed a critical representation as the majority. However, positive representations and a mute zone effect (silence of controversial opinions) were found. Participants also answered several questions about the regime, the emotions they feel, and the support for its restoration. Regression analyses showed different variables predicting positive and negative emotions, and positive representations strongly predicting support for a current authoritarian solution. (AU)


Este estudo analisou a estrutura das representações sociais de um regime autoritário no Brasil (Regime Militar, 1964-1985), as variáveis associadas ao relato de diferentes emoções sobre esse passado e o apoio a soluções autoritárias no presente. Uma amostra composta por 200 participantes de 18 a 85 anos (M = 31,54; DP = 13,84) respondeu à uma tarefa de associação livre de palavras na qual indicavam três palavras que lhes vinham à mente sobre o Regime Militar. Uma análise prototípica mostrou uma representação crítica como majoritária. Entretanto, foram encontradas representações positivas e um efeito de zona muda (silêncio de opiniões polêmicas). Os participantes também responderam a diversas questões sobre o regime, as emoções que sentiam e o apoio à sua volta. Análises de regressão mostraram diferentes variáveis prevendo emoções positivas e negativas, e que as representações positivas previam fortemente o apoio à uma solução autoritária atual. (AU)

ABSTRACT

Introduction Collecting high-dose (HD) or double-dose (DD) apheresis platelets units from a single collection offers significant benefit by improving inventory logistics and minimizing the cost per unit produced. Platelet collection yield by apheresis is primarily influenced by donor factors, but the cell separator used also affects the collection yield. Objectives To predict the cutoff in donor factors resulting in HD and DD platelet collections between Trima/Spectra Optia and MCS+ apheresis equipment using Classification and Regression Trees (CART) analysis. Methods High platelet yield collections (target ≥ 4.5 × 1011 platelets) using MCS+, Trima Accel and Spectra Optia were included. Endpoints were ≥ 6 × 1011 platelets for DD and ≥ 4.5 to < 6 × 1011 for HD collections. The CART, a tree building technique, was used to predict the donor factors resulting in high-yield platelet collections in Trima/Spectra Optia and MCS+ equipment by R programming. Results Out of 1,102 donations, the DDs represented 60% and the HDs, 31%. The Trima/Spectra Optia predicted higher success rates when the donor platelet count was set at ≥ 205 × 103/µl and ≥ 237 × 103/µl for HD and DD collections. The MCS+ predicted better success when the donor platelet count was ≥ 286 × 103/µl for HD and ≥ 384 × 103/µl for DD collections. Increased donor weight helped counter the effects of lower donor platelet counts only for HD collections in both the equipment. Conclusions The donor platelet count and weight formed the strongest criteria for predicting high platelet yield donations. Success rates for collecting DD and HD products were higher in the Trima/Spectra Optia, as they require lower donor platelet count and body weight than the MCS+.

ABSTRACT

Objective: Determining the appropriate approach for delivery after previous cesarean is a very controversial issue. Our objective was to establish whether pregnant women with a previous cesarean have an increased maternal and fetal morbidity and mortality after attempting vaginal delivery as well as to determine which factors may influence the achievement of a vaginal birth after cesarean. Materials and methods: A retrospective observational cohort study including 390 patients (196 cesarean group and 194 nulliparous group) was carried out. We compared neonatal and maternal outcomes between groups. Afterward, a multivariate logistic regression was applied for our second objective. Results: There were higher rates of uterine rupture (2% vs. 0%, p: 0.045) and puerperal hemorrhage (9.7% vs. 3.1%, p: 0.008) in the cesarean group and lower vaginal delivery rate (58.2% vs. 77.8%, p < 0.0005). We found that the induced onset of labor (OR = 2.9) and new born weight (OR = 1.0001) were associated with an increased risk of cesarean section. Conclusions: Our findings stress the need for further investigations in this field, which might provide a basis for a better management of patients with a previous cesarean.


Objetivo: Determinar el abordaje adecuado del tipo de parto tras una cesárea previa es un tema muy controvertido. Nuestro objetivo fue establecer si las gestantes con cesárea previa presentan mayor morbimortalidad materna y fetal tras intentar parto vaginal, así como determinar qué factores pueden influir en conseguir un parto vaginal posterior a la cesárea. Material y métodos: Estudio observacional de cohortes retrospectivo incluyendo 390 pacientes (196 con cesárea previa, 194 nulíparas). Comparamos los datos sobre los resultados neonatales y maternos. Posteriormente se aplicó un modelo de regresión logística multivariante. Resultados: Hubo mayores tasas de ruptura uterina (2% vs. 0%; p = 0.045) y hemorragia puerperal (9.7% vs. 3.1%, p: 0.008) en el grupo de cesárea anterior, así como una tasa de parto vaginal mas baja (58.2% vs. 77.8%, p < 0.0005). La inducción del parto (OR = 2,9) y el peso del recién nacido (OR = 1.0001) se asociaron a un mayor riesgo de cesárea. Conclusión: La probabilidad de parto vaginal en estas pacientes disminuye cuanto mayor sea el peso del recién nacido y con partos inducidos.

ABSTRACT

Introducción: la tuberculosis es considerada como un problema de salud pública a nivel mundial, siendo la decimotercera causa de muerte y la enfermedad infecciosa más mortífera detrás del COVID-19 y por encima de la infección por VIH, llegando a un total de 1.5 millones de muertes en el 2020. Colombia es el quinto país de la región con mayor carga de casos de tuberculosis, reportándose en el Programa Nacional de Tuberculosis un total de 13.037 casos preliminares en el 2020, representando una importante carga para el Sistema General de Seguridad Social en Salud. Material y métodos: se realizó un estudio observacional de corte retrospectivo con una población de 130 pacientes con diagnóstico de tuberculosis en una institución de tercer nivel en la ciudad de Bogotá, con el fin de identificar posibles factores de riesgo asociados al desarrollo de complicaciones en estos pacientes. Resultados y discusión: en el grupo total encontramos que la presencia de desnutrición es un factor de riesgo independiente para presentar complicaciones asociadas a la infección por tuberculosis; mediante análisis de regresión condicionada por método exacto se identifica un HR de 2.53 [1.008;6.378] (p 0.002) y HR ajustado de 1.47 [0.400-2.556] (p 0.007). El resto de condiciones no presentaron asociación estadísticamente significativa con el desarrollo de complicaciones en pacientes con diagnóstico de tuberculosis. Conclusiones: en los pacientes con diagnóstico de tuberculosis que asistieron al hospital Santa Clara entre 2017 y 2018, encontramos que un estado nutricional inadecuado tuvo una asociación significativa a la presencia de complicaciones relacionadas con infección por tuberculosis. Otros factores como el nivel de educación, estrato socioeconómico o la presencia de comorbilidades no demostraron una influencia significativa en el objetivo del estudio.


Introduction: Tuberculosis is considered a public health problem worldwide, being the thirteenth cause of death and the deadliest infectious disease behind COVID-19 and above HIV infection, reaching a total of 1, 5 million deaths in 2020. Colombia is the fifth country in the region with the highest burden of tuberculosis cases, reporting a total of 13,037 preliminary cases in 2020 in the National Tuberculosis Program, representing a significant burden for the General System of Social Security in Health. Materials and methods: A retrospective observational study was carried out with a population of 130 patients diagnosed with tuberculosis in a third level institution at Bogotá city, to identify factors associated with the development of complications in tuberculosis patients. Results and discussion: In the total group, the presence of malnutrition is found to be an independent risk factor for tuberculosis complications by means of a conditioned regression analysis using the exact method we found an OR of 2.53 [1.008;6.378] (p 0.00202) and adjusted OR of 1.47 [0.400-2.556] (p 0.007), neither of the other conditions can't be associated with the presence of complications in patients diagnosed with tuberculosis. Conclusions: In patients diagnosed with tuberculosis who attended the Santa Clara hospital between 2017 and 2018, we found that an inadequate nutritional status is associated with the presence of major complications. Other factors such as level of education, socioeconomic status or the presence of comorbidities do not show a significant influence on the objective of the study.
