RESUMO
ABSTRACT BACKGROUND: The cardiopulmonary function of patients with obstructive sleep apnea (OSA) is significantly lower than that of patients with simple snoring and is significantly related to the severity of OSA. Currently, only a few studies have been conducted on cardiopulmonary exercise testing in overweight patients with OSA. OBJECTIVE: To analyze the correlation between cardiopulmonary exercise test (CPET) indices and the condition of overweight patients with OSA. DESIGN AND SETTING: Retrospective study in Guangdong Provincial Hospital of Chinese Medicine. METHODS: This study included 73 hospitalized overweight patients. The patients were divided into no, mild, moderate, and severe OSA groups. Differences in the CPET indices among the four groups were compared. The correlation between the CPET indices and conditions was analyzed. RESULTS: No, mild, moderate, and severe OSA groups had 18 men and 5 women, 11 men and 3 women, 12 men and 2 women, and 21 men and 1 woman, respectively (P > 0.05). No significant difference was observed in resting pulmonary function among the four groups (P > 0.05). In the CPET, the anaerobic threshold, maximum oxygen uptake, and oxygen pulse were significantly lower in the severe OSA group than those in the normal OSA group (P < 0.05). Moreover, CPET indices negatively correlated with the apnea-hypopnea index. CONCLUSION: Changes in CPET indices occurred earlier than changes in resting pulmonary function in patients with OSA. CPET might be a potential method for evaluating the severity of OSA combined with overweight status.
RESUMO
Abstract Objectives: This experimental study focused on the intra- and inter-rater reproducibility of vertical bone level (VBL) measurements at strategic mini-implants (MI) using digital panoramic radiographs (PR). Study design: VBLs of 152 MIs for removable partial denture stabilization at 50 randomly chosen PRs from a clinical trial were digitally evaluated by three ratters. Rater deviations exceeding 0.5 mm were re-examined. The intra-class correlation coefficient (ICC) was applied to estimate reliability. The smallest detectable change (SDC) was interrelated to the minimal clinically important change of 0.2 mm. Results: The first measurement round revealed intra- and inter-rater ICCs of > 0.8. However, 28 sites (9 %) were unreadable, and 97 sites (32 %) revealed differences between observers of ≥ 0.5 mm. Following a consensus session and re-training, an additional 8 sites were excluded and all remaining VBL differences were ≤ 0.5 mm. Thus, the SDCs with 95 % credibility were improved from 0.73 to 0.31 mm in the intra-rater and from 1.52 to 0.34 mm in the interrater statistics. Given a 50 % credibility for this special setting, both the intra- and inter-rater SDCs were 0.11 mm. Conclusions: Digital PR can be reliably utilized to determine VBLs around MIs under conditions of at least two trained observers, mutual calibration sessions, and exclusion of unquantifiable radiographs.

RESUMO
AIM: To explore the correlation between neonatal retinal hemorrhage(RH)and changes in umbilical artery blood gas analysis.METHODS: A total of 312 full-term neonates born in our obstetrics department from January 2019 to December 2021 were selected as the study subjects. According to the RetCam III fundus examination results, 245 neonates who did not experience RH were included in the control group, while 67 cases with RH were found to be included in the RH group. In addition, neonates were grouped into I degree group(n=20), II degree group(n=29), and III degree group(n=18)based on the degree of RH. General clinical data and umbilical artery blood gas analysis indicators between the RH group and the control group were compared; the levels of umbilical artery blood gas analysis indicators in neonates with different degrees of RH, the relationship between pH and RH degree, and the influencing factors of neonatal RH were analyzed.RESULTS: There was no obvious difference in maternal age, average gestational week, fetal gender, parity, gestational diabetes, fetal birth weight, and amniotic fluid between the RH group and the control group(all P>0.05), while there were obvious differences in delivery methods, gestational hypertension, forceps assisted delivery, neonatal asphyxia, and umbilical cord around the neck(all P<0.05). The pH value, arterial blood sample partial pressure(PaO2)and base excess(BE)values of the RH group were obviously lower than those of the control group(all P<0.01), while the arterial carbon dioxide partial pressure(PaCO2)was obviously higher than that of the control group(P<0.01). There were obvious differences in umbilical artery blood gas analysis indicators among children with different degrees of RH(P<0.05), and with the increase of the degree of RH, pH value, PaO2 and BE gradually decreased(P<0.05), and PaCO2 gradually increased(P<0.05). There was a negative correlation between the degree of RH and the pH of umbilical artery blood gas analysis(rs=-0.593, P<0.05). The results of multivariate Logistic regression analysis showed that delivery method, gestational hypertension, forceps assisted delivery, neonatal asphyxia, umbilical cord entanglement, pH, PaO2, PaCO2, and BE were all influencing factors for the occurrence of neonatal RH.CONCLUSION: There is a close correlation between neonatal RH and changes in umbilical artery blood gas analysis, and umbilical artery blood gas analysis can be used for the diagnosis of neonatal RH, which can be used to guide clinical treatment.
RESUMO
ObjectiveTo investigate the association between urinary thallium （TL） and nonalcoholic fatty liver disease （NAFLD）. MethodsRelated data were collected from the registered participants aged ≥18 years in National Health and Nutrition Examination Survey from 2017 to 2020， with th exclusion of the individuals with a lack of liver transient elastography data and urinary TL indicators and those with hepatitis B， hepatitis C or significant alcohol consumption. A total of individuals were divided into NAFLD group and non-NAFLD group. Urinary TL level was quantitatively measured using high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry and online solid-phase extraction combined with isotope dilution. The two groups were compared in terms of age， sex， race， marital status， education， family income poverty impact ratio （FMPIR）， body mass index （BMI）， smoking， alcohol consumption， diabetes mellitus （DM）， hypertension （HTN）， hyperlipidemia （HL）， and urinary TL level. The independent-samples t test or the Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. Descriptive analysis， multivariable Logistic regression， restricted cubic spline regression analysis， subgroup analysis， and interaction analysis were conducted to investigate the risk association between urinary TL and NAFLD. ResultsA total of 2 511 individuals were included， with 1 612 （64.20%） in the NAFLD group and 899 （35.80%） in the non-NAFLD group， and the NAFLD group had a significantly higher urinary TL level than the non-NAFLD group ［0.18 （0.11 — 0.26）μg/L vs 0.16 （0.09 — 0.25）μg/L， Z=-2.76， P=0.01］. After adjustment for the covariates of age， sex， race， education， marital status， FMPIR， BMI， smoking， alcohol consumption， DM， HTN， and HL， the urinary TL Q4 group had a significant increase in the risk of NAFLD （odds ratio ［OR］=1.90， 95% confidence interval ［CI］： 1.48 — 2.44， P<0.01）. There was a positive dose-response relationship （P<0.01） and a non-linear relationship （P<0.01） between urinary TL and the risk of NAFLD. A significant interaction was observed between urinary TL and smoking/BMI （P<0.05）. For individuals taking ≥100 cigarettes in their lifetime， the risk of NAFLD was increased by 50% for every quartile increase in urinary TL （OR=1.50， 95%CI： 1.24 — 1.80）， and for individuals taking<100 cigarettes in their lifetime， the risk of NAFLD was increased by 20% for every quartile increase in urinary TL （OR=1.20， 95%CI： 1.03 — 1.40）； for individuals with a BMI of ≥30 kg/m2， the risk of NAFLD was increased by 30% for every quartile increase in urinary TL （OR=1.30， 95%CI： 1.05 — 1.70）， with a statistical significance （P<0.05）. ConclusionUrinary TL level is significantly associated with the risk of NAFLD.
RESUMO
Objective @#To examine the association between intrinsic capacity and falls in older adults, so as to provide insights into the risk assessment of falls. @*Methods@#Older adults aged 60 years and above were selected from two districts and one county in Bengbu City, Anhui Province from September 2022 to June 2023 using convenience sampling method. Demographic information, health-related behaviors and incidence of falls among participants were collected through questionnaire surveys. The intrinsic capacity included five dimensions: sensory, motor, vitality, cognition and psychology, which were investigated by the sensory dimension screening scale recommended by the World Health Organization, the Simple Physical Functioning Battery (SPPB), the Micro Nutritional Assessment Scale (MNAS-SF), the Brief Intelligent Mental State Examination Scale (MMSE), and the Center for Evaluation of Streamlined Depression Levels 10-entry scale (CESD-10), respectively. A total score of 1 or more indicated a decrease in intrinsic capacity. The association between intrinsic capacity and falls in older adults was analyzed by a multivariable logistic regression model.@*Results@#A total of 1 950 questionnaires were allocated, and 1 917 were valid, with an effective rate of 98.30%. There were 934 men (48.72%) and 983 women (51.28%), with a mean age of (68.15±3.42) years. There were 1 352 rural residents (70.53%) and 1 431 illiterate and primary school-educated residents (74.65%). In the past year, 347 residents fell, accounting for 18.10%. The median comprehensive score for intrinsic capacity was 1.00 (interquartile range, 2.00) points, and 1 320 had a decrease in intrinsic capacity, accounting for 68.86%. Multivariable logistic regression analysis showed that decline in intrinsic ability was associated with the risk of falls after adjustment for age, gender, educational level, marital status, alcohol consumption and self-rated health status (OR=1.531, 95%CI: 1.408-1.721).@*Conclusion@#Decreased intrinsic capacity in older adults may contribute to an increased risk of falls.
RESUMO
Alzheimer's disease (AD) is a central nervous system degenerative disease that is prone to occur in the pre-senile period and senile period . It is characterized by behavioral impairment and progressive cognitive impairment, with an insidious onset and progressive aggravation. It not only has cognitive decline, but also is accompanied by other neurological and psychiatric symptoms. Memory loss is the core symptom of the disease. Diabetes mellitus (DM) is a disease characterized by hyperglycemia. In recent years, with the increasing incidence of the two diseases, more and more studies have reported the correlation between AD and DM. This article reviews the correlation between AD and DM from the aspects of correlation research, pathological mechanism and drug treatment through the review of relevant literature, with a view to providing guidance for clinical practice.
RESUMO
OBJECTIVE To investigate the effects of GSTP1， XRCC1， ABCB1， MTHFR gene polymorphisms on efficacy and toxic effect of chemotherapy regimen containing oxaliplatin in patients with stage Ⅲ and Ⅳ colorectal cancer patients. METHODS Clinical data of 76 patients with stage Ⅲ and Ⅳ colorectal cancer who received chemotherapy regimen containing oxaliplatin （XELOX，FOLFOX） were collected from the Second Affiliated Hospital of Soochow University from September 2018 to March 2020. The correlation of genotypes with progression-free survival （PFS） and toxic effect was analyzed by using univariate and multivariate COX regression model. RESULTS Carriers of the ABCB1 3435T＞C locus C allele （TC/CC） had a significantly higher risk of progression compared to TT genotype patients [HR＝2.39， 95%CI （1.05，5.50）， P＝0.038]. The risk of progression in patients at stage Ⅳ was significantly higher than those at stage Ⅲ [HR＝8.11， 95%CI（3.39，19.40）， P＜0.001]. Chemotherapy regimen， Karnofsky performance status score and tumor site had no significant effect on disease progression （P＞0.05）. Mutations in gene loci were not correlated with adverse reactions （P＞0.05）. CONCLUSIONS Patients carrying ABCB1 TC/CC and receiving chemotherapy regimen containing oxaliplatin have a higher risk of disease progression， which may be associated with longer PFS in patients （TT genotype） with stage Ⅳ colorectal cancer receiving the chemotherapy， while GSTP1， XRCC1， and MTHFR gene polymorphisms have no significant impact.
RESUMO
OBJECTIVE To evaluate the comprehensive quality of Houttuynia cordata from different producing areas. METHODS Using total flavonoids， water-soluble extract， moisture， total ash and acid-insoluble ash as indicators， the entropy weight method was used to objectively weigh each indicator， and the relative correlation degree （r）i calculated by grey correlation method was used as a measure to comprehensively evaluate the quality of H. cordata. RESULTS The weights of total flavonoids， total ash， moisture， acid-insoluble ash， and water-soluble extract were 0.295 5， 0.227 3， 0.188 7， 0.145 1， and 0.143 4， respectively. The weights of total flavonoids and total ash were relatively large. The ri of 30 batches of H. cordata ranged from 0.233 2 to 0.673 9； the average ri of samples from Quanzhou County and Ziyuan County of Guangxi Zhuang Autonomous Region were the highest， which were 0.638 3 and 0.598 7， respectively， followed by samples from Lingchuan County of Guangxi Zhuang Autonomous Region （0.556 1） and Jianshui County of Yunnan Province （0.452 8）. The quality of medicinal materials produced in the above producing areas was generally good and stable. CONCLUSIONS Entropy weight method combined with the grey correlation method can be used to comprehensively evaluate the quality of H. cordata. The overall quality of H. cordata produced in Quanzhou County of Guangxi Zhuang Autonomous Region is the best.
RESUMO
ObjectiveTo analyze the expression of molecular marker affecting the prognosis of acute myeloid leukemia （AML） patients from bioinformatics database， thus providing an experimental basis for further exploration of a novel molecular marker for the prognosis of AML. MethodsThe prognostic data of 179 AML patients from The Cancer Genome Atlas （TCGA） database were examined for differential gene analysis and survival analysis. The bone marrow samples of 74 healthy individuals （HI） and 542 de novo AML patients in the dataset GSE13159 downloaded from the Gene Expression Omnibus （GEO） database were analyzed to detect the difference in the expression levels of differential target genes. Peripheral blood and bone marrow samples were collected from 18 de novo AML patients and 20 age- and gender-matched healthy controls， and real-time fluorescent quantitative PCR was used to validate the expression levels of the differential genes in the AML patients. ResultsBioinformatics data analysis showed that the optimal cut-off value of Homo sapiens NK2 homeobox 3 （NKX2-3） calculated by R language was 0.051. Survival analysis revealed a statistically poorer overall survival in de novo AML patients with high NKX2-3 expression than in those with low NKX2-3 expression （P = 0.0036）. NKX2-3 was highly expressed in patients with de novo AML than in HI and the difference was statistically significant （P < 0.001）. Real-time fluorescence quantitative PCR verified the expression levels of the NKX2-3 gene in AML patients and confirmed that compared with those in HI， in the de novo AML patients， NKX2-3-1 and NKX2-3-2 were highly expressed and were significantly correlated （P = 0.000， P = 0.000）. ConclusionNKX2-3 is highly expressed in de novo AML patients， and the AML patients with high NKX2-3 expression have poor overal survival. NKX2-3 may be closely related to the clinical outcome and prognosis of AML.
RESUMO
ObjectiveTaking Achyranthis Bidentatae Radix（ABR） from different origins as samples， to quantitatively analyze the chemical composition and chromaticity of ABR with different processing degrees， and clarify the correlation and change law between color and composition in the processing process of ABR， so as to provide reference for the quality evaluation of processed products of ABR. MethodThe colorimeter is used to measure the chromaticity values of three kinds of processing degrees of ABR in different origins to show the color value change trend during the processing process， and the color parameters of wine-processed and salt-processed products of ABR with different processing degrees were analyzed by principal component analysis（PCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA） and other analysis methods. The contents of eight representative components of ABR were measured by high performance liquid chromatography（HPLC）， the correlation between chromaticity and each representative component was analyzed by Pearson correlation analysis， and the applicability of the selected eight representative components was further verified by Fisher linear discriminant analysis， and the wine-processed and salt-processed products of ABR with different processing degrees were grouped according to the degree of processing， and 48 samples of wine-processed and salt-processed products with different processing degrees were used as training samples. Taking the contents of 5-hydroxymethylfurfural， polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone， ginsenoside Ro， chikusetsusaponin Ⅳa and polysaccharides as variables， the discriminant function was established respectively， and 12 samples of wine-processed and salt-processed products of ABR with different processing degrees were back-tested to verify the discriminant function and test the reliability of the function. ResultPCA and OPLS-DA results showed that ABR samples with different processing degrees were classified into clusters， and the results could significantly distinguish different processed products. During the process of wine and salt processing， the contents of 5-hydroxymethylfurfural， ginsenoside Ro， and chikusetsusaponin Ⅳa gradually increased with the deepening of the processing degree， while the contents of polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone and polysaccharides showed a gradual decreasing trend， indicating these 8 components increased and decreased to different degrees in the process of wine and salt processing. The results of Pearson correlation analysis showed that the 5-hydroxymethylfurfural content of the samples with different processing degrees of wine-processed and salt-processed products were negatively correlated with the brightness value（L*） and the total color difference value（E*ab）（P<0.01）， and positively correlated with the red-green value（a*） and the yellow-blue value（b*）（P<0.01）， and that the content of polypodine B and polysaccharides were positively correlated with L* and E*ab（P<0.01）. The discriminant functions of wine-processed and salt-processed products of ABR were established by Fisher linear discriminant analysis， and their accuracy rates in the training samples were 93.75% and 95.83%， respectively. Twelve test samples of wine-processed and salt-processed products with different processing degree were back substitution， and the correct rate was 100%. ConclusionThe trend of composition and color changes of ABR with different processing degrees in different production areas is relatively consistent， and the color value can better distinguish ABR with different processing degrees， and the color of ABR is related to some representative components in the processing process， indicating that the color can provide reference for the identification of the processing degree of ABR and the prediction of component content.
RESUMO
ObjectiveTo explore the scientific connotation of fried charcoal survivability of Lonicerae Japonicae Flos（LJF） by analyzing the correlation between the color change and the intrinsic components during the processing of LJF Carbonisata（LJFC）， and taking pH， charcoal adsorption and microscopic characteristics as indexes. MethodLJFC samples with different degrees of processing were prepared according to the stir-frying time of 0.0， 1.5， 3.0， 4.5， 6.0， 7.5， 9.0， 10.5 min（numbered S1-S8）， and the contents of gallic acid， chlorogenic acid， cryptochlorogenic acid， rutin， luteoloside， isochlorogenic acid A and isochlorogenic acid C were determined by high performance liquid chromatography（HPLC）， and the L*（brightness）， a*（red-greenness） and b*（yellow-blueness） of LJFC samples with different degrees of processing were determined by spectrophotometer， and the correlation analysis and principal component analysis（PCA） between the contents of seven representative components and the color of the samples were carried out by SPSS 26. 0 and SIMCA-P 14.1. Then pH， adsorption force and characteristic structure of different samples of LJFC were detected and the processing pattern of LJFC was analyzed. ResultThe results of quantitative analysis revealed that the contents of luteoloside， rutin， chlorogenic acid and isochlorogenic acid A gradually decreased， and the contents of cryptochlorogenic acid， isochlorogenic acid C and gallic acid firstly increased and then decreased. The L* and b* of the sample powders decreased， and a* showed a trend of increasing and then decreasing. The L* and b* were positively correlated with the contents of chlorogenic acid， rutin， luteoloside， isochlorogenic acid A， b* was positively correlated with the content of gallic acid， and a* was positively correlated with the contents of cryptochlorogenic acid and isochlorogenic acid C. PCA revealed that samples could be clearly divided into 3 groups， S1-S2 as one group， S3-S5 as one group， and S6-S8 as one group， with S3 having the highest score. The results of regression analysis showed that only isochlorogenic acid C could be used to predict the contents of components by colorimetric values combined with regression equations. Physicochemical analysis showed that pH of LJFC increased with the increase of degree of charcoal stir-frying， while adsorption force showed a tendency of increasing and then decreasing， with the highest adsorption force in the S5 sample， and the non-glandular hairs， calcium oxalate clusters and pollen grains had a varying degree of decreasing with the deepening of processing degree， and the microstructures of S6-S8 samples were obviously charred with pollen grains almost invisible. ConclusionThe changes in chemical composition and color characteristics of LJFC during the processing have certain correlations， combined with the changes in physicochemical properties， S5 sample is found to be the optimal processed products， which can provide a reference for the processing standardization and quality evaluation of LJFC， and enrich the scientific connotation of fried charcoal survivability of LJF.

RESUMO
Introducción: Algunos estudios han encontrado relación entre exceso de peso y baja fuerza de prensión relativa. En países de ingresos socioeconómicos medianos y bajos hay pocas evidencias que evalúen la fuerza prensil y su relación con la composición corporal en población pediátrica. Objetivo: Evaluar la correlación entre la fuerza prensil y la composición corporal de escolares de Bucaramanga, Colombia. Materiales y métodos: Se realizó un estudio piloto de corte transversal, analítico, correlacional. Participaron niños en edad escolar de Bucaramanga, Colombia. Las principales variables dependientes fueron masa muscular, agua corporal total, proteínas (kg) y el porcentaje de grasa corporal. La variable independiente correspondió a la fuerza prensil. Se usó el coeficiente de correlación de Spearman para explorar la relación entre variables. Resultados: El promedio de la fuerza prensil en el total de la muestra fue de 13,8 ± 3,2 Newton. Se encontraron correlaciones positivas y estadísticamente significativas entre la fuerza prensil y la masa musculoesquelética (r = 0,73), agua corporal total (r = 0,73) y proteínas (r = 0,74). Discusión: Nuestros resultados son consistentes con evidencias previas que identifican a la fuerza prensil como un indicador de la composición corporal, específicamente en las variables de masa musculoesquelética y proteínas. Conclusión: Los niños en el tercil más alto de fuerza prensil presentan los terciles más altos de masa musculoesquelética, agua corporal total y proteínas.
Introduction: Some studies have found a relationship between excess weight and low relative grip strength. In countries with medium and low socioeconomic income, there is little evidence evaluating grip strength and its relationship with body composition in the pediatric population. Objective: To evaluate the correlation between grip strength and body composition of schoolchildren from Bucaramanga, Colombia. Materials and Methods: A cross-sectional, analytical, correlational pilot study was conducted. Schoolchildren from Bucaramanga, Colombia participated. The main dependent variables were muscle mass, total body water, protein (kg), and percentage of body fat. The independent variable corresponded to the prehensile force. Spearman's Correlation Coefficient was used to explore the relationship between variables. Results: The average prehensile force in the total sample was 13.8±3.2 Newton. Positive and statistically significant correlations were found between grip strength and musculoskeletal mass (r=0.73), total body water (r=0.73), and protein (r=0.74). Discussion: Our results are consistent with previous evidence that identifies grip strength as an indicator of body composition, specifically in the variables of musculoskeletal mass and protein. Conclusion: Children in the highest tertile of prehensile strength present the highest tertiles of skeletal muscle mass, total body water, and protein.

Método: diseño comparativo, correlacional y transversal. La muestra utilizada (n=271) constituyó el 40,9% del total de profesionales de enfermería. Se estudiaron las propiedades psicométricas de la Escala de Empatía de Jefferson para Profesionales de la Salud. Se calcularon estadísticos descriptivos: media y desviación estándar. La asociación entre empatía y edad se estimó mediante ecuaciones de regresión y significancia estadística de los coeficientes de regresión, luego de evaluar el tipo de curva mediante análisis de varianza. Resultados: se identificó el modelo subyacente de las tres dimensiones de la empatía. Los valores de los estadísticos descriptivos observados fueron relativamente bajos en empatía y sus dimensiones. Los niveles de empatía no se asociaron con el rango de edad. No se encontraron diferencias en la empatía entre los tipos de horarios de trabajo. Se encontró variabilidad en las dimensiones: "cuidado compasivo" y "ponerse en los zapatos del paciente". Conclusión: estos resultados muestran que los niveles de empatía observados pueden implicar un desempeño deficiente en el cuidado empático de los pacientes.
Objective: to determine the levels of empathy in professional nurses of a high-complexity hospital, to relate age to empathy (and each one of its dimensions), and to establish if there are differences between these levels according to the type of working schedules. Method: comparative, correlational and cross-sectional design. The sample used (n=271) constituted 40.9% of the total number of nursing professionals. Psychometric properties of the Jefferson Scale of Empathy for Health Professionals were studied. Descriptive statistics were calculated: mean and standard deviation. The association between empathy and age was estimated using regression equations and statistical significance of the regression coefficients, after evaluating the type of curve using variance analysis. Results: the underlying model of three dimensions of empathy was identified. The values of the descriptive statistics observed were relatively low in empathy and its dimensions. Empathy levels were not associated with the age range. No differences in empathy were found between the types of work schedules. Variability was found in the dimensions: "compassionate care" and "Walking on the patient's shoes". Conclusion: these results show that the levels of empathy observed may imply a deficient performance in empathetic care for patients.

Se realizó un estudio transversal en 231 estudiantes universitarios que ingresaron a las Facultades de Salud y Educación en el primer semestre del año 2019. Para poder evaluar el rendimiento, a los estudiantes se les aplicó el cuestionario de Índice de Estilos de Aprendizaje y se correlacionó con la nota de la prueba teórica 1, la evaluación práctica 1 y el promedio final de la asignatura. Los resultados muestran que el 53,4 % del total de estudiantes evaluados son visuales, para estos estudiantes el coeficiente de correlación de Spearman fue de -0,378 para prueba teórica (p<0,001), -0.467 para evaluación práctica (p<0,001) y -0.500 para el promedio final (p<0,001). Los estudiantes visuales tienen promedio de notas más altos en la prueba teórica y el promedio final comparado con los activos (p<0,05). Se concluyó que la tendencia predominante es el visual, para estos estudiantes existe una correlación inversa y estadísticamente significativa con el rendimiento académico. Además, presentan un promedio de notas significativamente más alto que las otras tendencias.
SUMMARY: The objective if this study was to determine the relation that exists between the predominant tendency of the learning style, according to the Felder-Silverman model, and partial and final academic performance of the students attending the subject Morphology and Function I. A transversal study was carried out among 231 college students who joined the Faculties of Health and Education during the first term of 2019. They received the Index of Learning Styles Questionnaire and it was correlated with the mark of the theoretical test n°1, the practical evaluation n° 1 and the final average of the course. Results showed that 53.4 % of the total numbers of students assessed are visual, for these pupils the Spearman correlation coefficient was -0.378 for the theoretical test (p<0.001),-0.467 for the practical evaluation (p<0.001) and -0.500 for the final average (p<0.001). Visual students have higher average marks in the theoretical test and the final average contrasted with the active ones (p<0.05). We concluded that the predominant tendency is the visual style. For these students there is an inverted and statistically significant correlation with the academic performance. Besides, they show significantly higher average marks than the other tendencies.

Introducción: la alanina aminotransferasa es un nexo importante en el metabolismo de aminoácidos y carbohidratos, asimismo es un marcador de inflamación hepática. Estudios previos mostraron la relación entre la diabetes mellitus y esta enzima bajo diferentes contextos clínicos. Objetivo: evaluar la correlación entre glucosa basal y alanina aminotransferasa tanto en pacientes con diabetes mellitus tipo 2 como sin ella. Metodología: estudio observacional, analítico y transversal realizado desde enero de 2021 a junio de 2022 con una población de 566 pacientes dividida en grupos con diabetes mellitus tipo 2 (n 224) y sin diabetes mellitus tipo 2 (n 342). Fueron incluidos los pacientes de edad igual o mayor a 18 años con y sin diabetes mellitus tipo 2. Se excluyó a pacientes con patologías múltiples y/o con diagnóstico de diabetes inferior a 6 meses. Se realizó el análisis inferencial con la prueba de correlación de Spearman y la prueba de normalidad de Kolmogorov-Smirnov. Los datos fueron procesados con el software SPSS statistics 25™. Resultados: la correlación entre glucosa y alanina aminotransferasa en sujetos sin diabetes fue 0,212 (p=0,003) y la correlación entre glucosa y alanina aminotransferasa en aquellos con diabetes fue -0,434 (p=0,015). Conclusiones: la alanina aminotransferasa se relaciona con mayor intensidad en pacientes con diabetes mellitus tipo 2 que en aquellos sin diabetes. La correlación moderada y negativa en sujetos con diabetes mellitus tipo 2 indicaría alteraciones en la interacción entre la alanina aminotransferasa y la glucosa en los que la hiperglucemia sostenida tendría un papel relevante, probablemente por un incremento en la actividad de transaminación.
Introduction: Alanine aminotransferase is an important nexus in the metabolism of amino acids and carbohydrates, and is also a marker of liver inflammation. Previous studies showed the relationship between diabetes mellitus and this enzyme under different clinical contexts. Objective: To evaluate the correlation between basal glucose and alanine aminotransferase both in patients with and without type 2 diabetes mellitus. Methodology: Observational, analytical, and cross-sectional study conducted from January 2021 to June 2022 with a population of 566 patients divided into groups with type 2 diabetes mellitus (n 224) and without it (n 342). Patients aged 18 years or older with and without type 2 diabetes mellitus were included. Patients with multiple pathologies and/or diagnosed with diabetes less than 6 months were excluded. Inferential analysis was performed with Spearman's correlation test and the Kolmogorov-Smirnov normality test. The data was processed with the SPSS statistics 25™ software. Results: The correlation between glucose and alanine aminotransferase in subjects without diabetes was 0.212 (p=0.003) and the correlation between glucose and alanine aminotransferase in those with diabetes was -0.434 (p=0.015). Conclusions: Alanine aminotransferase is associated with greater intensity in patients with type 2 diabetes mellitus than in those without diabetes. The moderate and negative correlation in subjects with type 2 diabetes mellitus would indicate alterations in the interaction between alanine aminotransferase and glucose in which sustained hyperglycemia would play a relevant role, probably due to an increase in transamination activity.
RESUMO
ABSTRACT BACKGROUND AND OBJECTIVES: Particular pain features, such as pain interference, neuropathic-like symptoms, and central sensitization (CS) symptoms may be present in patients with Chikungunya fever and lead to functional limitations. The present study aimed to assess the association between pain characteristics and the disability in participants affected by Chikungunya fever in the chronic phase. METHODS: A cross-sectional study was conducted with 36 participants who filled out a sociodemographic, pain characteristics (pain interference - Brief Pain Inventory, neuropathic-like symptoms - PainDETECT Questionnaire, and CS-related signs and symptoms - Central Sensitization Inventory) and disability (Health Assessment Questionnaire) questionnaires. The Spearman correlation test (rho) verified the relationship between the outcomes. RESULTS: Most of the participants were female (77%), with a mean age of 43 years. Twenty-seven (75%) participants presented nociceptive pain and 11 (30%) had central sensitization symptoms. There was a high positive correlation between the presence of neuropathic-like symptoms and disability (rho=0.71; p<0.001) and pain intensity and disability (rho=0.76; p<0.001). A moderate positive correlation was found between the central sensitization symptoms and disability (rho=0.51; p=0.002). Moreover, there is a low positive correlation between pain interference in an individual's life and disability (rho=0.34; p=0.041). CONCLUSION: Patients in chronic phase of Chikungunya fever revealed mild pain intensity and predominance of nociceptive pain. Pain interference, neuropathic-like symptoms, and central sensitization symptoms negatively impact individual's disability after Chikungunya fever.
RESUMO JUSTIFICATIVA E OBJETIVOS: Características particulares da dor, como interferência da dor, sintomas do tipo neuropático e sintomas de sensibilização central (SC), podem estar presentes em pacientes com febre Chicungunha e levar a limitações funcionais. O presente estudo teve como objetivo avaliar a correlação entre as características da dor e a capacidade funcional em participantes acometidos pela febre Chicungunha na fase crônica. MÉTODOS: Foi realizado um estudo transversal com 36 participantes que preencheram questionários sociodemográficos, de características de dor (interferência da dor - Inventário Breve de Dor, sintomas do tipo neuropático - questionário PainDETECT, e sinais e sintomas relacionados à SC - Inventário de Sensibilização Central) e de capacidade funcional (Health Assessment Questionnaire). O teste de correlação de Spearman (rho) verificou a relação entre os desfechos. RESULTADOS: A maioria dos participantes era do sexo feminino (77%), com média de idade de 43 anos. Vinte e sete (75%) participantes apresentaram dor nociceptiva e 11 (30%) apresentaram sintomas de sensibilização central. Houve alta correlação positiva entre a presença de sintomas do tipo neuropático e capacidade funcional (rho=0,71; p<0,001) e intensidade da dor e capacidade funcional (rho=0,76; p<0,001). Foi encontrada uma correlação positiva moderada entre os sintomas de sensibilização central e a capacidade funcional (rho=0,51; p=0,002). Além disso, há uma correlação positiva baixa entre a interferência da dor na vida do indivíduo e a capacidade funcional (rho=0,34; p=0,041). CONCLUSÃO: Pacientes em fase crônica da febre Chicungunha apresentaram intensidade de dor leve e predominância de dor nociceptiva. A interferência da dor, os sintomas do tipo neuropático e os sintomas de sensibilização central afetam negativamente a capacidade funcional do indivíduo após a febre Chicungunha.
RESUMO
La agresividad se ha reconocido como prevalente en la población adolescente, debido a su carácter impulsivo y de inestabilidad emocional, que también caracteriza a la adolescencia. Ello lleva a la necesidad de conocer la frecuencia y la relación de los factores de riesgo de la agresividad en población adolescente, explorando sus diferencias según sexo. Así, esta investigación de enfoque cuantitativo, diseño no experimental, transversal de alcance correlacional, estudió la presencia y las relaciones entre la agresividad y sus factores de riesgo en 212 mujeres y 188 hombres adolescentes, entre 12 y 17 años de edad. Para lo cual, se aplicó una ficha de valoración de factores de riesgo y el cuestionario de agresividad premeditada e impulsiva (CAPI-A). Los hallazgos muestran mayor prevalencia de agresividad impulsiva, y la presencia de más relaciones con factores de riesgo en mujeres respecto a los hombres. Los factores de riesgos relevantes en las mujeres son las actitudes hacia la norma, la percepción sobre la agresividad y los sentimientos; en los hombres, las conductas de riesgo y los sentimientos. Esto resulta de utilidad para la comprensión de la agresividad como pauta comportamental, y el diseño de intervenciones preventivas de la agresividad y sus consecuencias.
The aggressiveness has been recognized as prevalent in teenage population due to their impulsive character, with that emotional instability which characterizes adolescence. This conducts to the need of knowing the frequency and the relationship of risk factors of aggressiveness in teenage population, exploring their differences according to sex. Thus, this research of quantitative approach, non-experimental design, cross-sectional of correlational scope, studied the presence and the relations between aggressiveness and its risk factors in 212 teenage women and 188 teenage men between 12 and 17 years of age. For this, a record card of risk factor evaluation was implemented along with the questionnaire of premediated / impulsive aggressiveness (CAPI-A in Spanish). The findings show a higher prevalence of impulsive aggressiveness and the presence of more relations to risk factors in women than in men. The relevant risk factors in women are the attitudes towards norms, the perception about aggressiveness and the feelings; in men, risk conducts and feelings are the ones to mention. These results useful for the comprehension of aggressiveness as a behavioral pattern, and the design of preventive interventions towards aggressiveness and their consequences.
RESUMO
A sífilis e a infecção causada pelo vírus HIV constituem importantes problemas de saúde pública, em razão das altas taxas de morbimortalidade e do impacto que causam aos programas e às políticas públicas de saúde, tanto de forma isolada quanto no caso de coinfecção. Mesmo a sífilis sendo uma doença curável, e o HIV/aids uma doença que possui tratamento, ambas têm atingido milhões de pessoas no mundo, inclusive no Brasil, onde o estado da Bahia se destaca pelos elevados índices de infecção. Esse quadro se intensifica quando se observam as notificações conforme a raça/cor da pele, havendo um grande número de casos entre jovens negros. Esta dissertação pretende analisar a dinâmica espaçotemporal das taxas de internação por sífilis e HIV/aids em adultos, nas Regiões de Saúde da Bahia, no período de 2000 a 2020. Os dados são provenientes do Sistema de Informações Hospitalares (SIH), disponibilizado pelo Departamento de Informática do Sistema Único de Saúde (DATASUS), enquanto os dados populacionais e de raça/cor da pele são do Instituto Brasileiro de Geografia e Estatística (IBGE). As análises envolveram tanto medidas descritivas quanto tendência temporal, autocorrelação e correlação cruzada. Nesse ínterim, foram utilizados o método detrended fluctuation analysis (DFA), para caracterizar a autocorrelação e identificar a persistência na série temporal; o coeficiente de correlação cruzada ρDCCA, para mensurar a correlação cruzada entre as séries; e a média móvel, para caracterizar a tendência. Também foi realizada a análise descritiva, com a estimativa da tendência temporal por meio do modelo de regressão linear, com correção de Prais-Winsten. No período de 2000 a 2020, foram registradas 16.454 internações, sendo 3,2% por sífilis e 96,8% por HIV/aids. Quanto ao estudo de base temporal, foi identificado um comportamento persistente (αDFA > 0,50) e uma correlação negativa fraca (< 0,20) tanto entre as taxas de sífilis quanto entre as de HIV/aids, sendo estatisticamente significante somente a autocorrelação da sífilis. Os jovens negros constituíram a maioria dos sujeitos hospitalizados, com média geral de idade de 39,2 anos, prevalência do sexo feminino para sífilis (60,5%) e do sexo masculino para HIV/aids (61,8%). As maiores taxas de sífilis foram encontradas nas regiões de saúde de Itabuna, Ilhéus, Paulo Afonso e Salvador. O comportamento da sífilis foi estatisticamente significante (p < 0,05), com variação percentual anual (VPA) de 14,1% (ß1 > 0 e p < 0,05), o que denota uma tendência crescente. Para os casos de HIV/aids, as maiores taxas foram observadas nas regiões de Salvador, Camaçari, Teixeira de Freitas e Seabra. Não houve significância estatística para HIV/aids (p > 0,05), sendo o VPA de 1,6% (ß1 > 0 e p < 0,05), o que também indica uma tendência crescente. Espera-se que, com esta pesquisa, seja possível contribuir não somente para a atualização do conhecimento sobre infecção por sífilis e HIV/aids em adultos, mas principalmente para a construção de indicadores e para o planejamento e fortalecimento das políticas públicas de saúde, com ênfase nos sistemas de vigilância do estado da Bahia.
Syphilis and the infection by the HIV virus are important public health problems, due to the high rates of morbidity and mortality and the impact they cause to public health programs and policies, both in isolation and in cases of co-infection. Even though syphilis is a curable disease, and HIV/AIDS is a disease that has treatment, both have reached millions of people around the world, including Brazil, where the state of Bahia stands out for its high infection rates. This picture is intensified when the notifications according to race/skin color are observed, since there is a large number of cases among young black people. This dissertation intends to analyze the spatiotemporal dynamics of hospitalization rates for syphilis and HIV/AIDS in adults, in the Health Regions of Bahia, from 2000 to 2020. The data came from the Hospital Information System (SIH), made available by the Department of Informatics of the Unified Health System (DATASUS), and the population and race/skin color data came from the Brazilian Institute of Geography and Statistics (IBGE). Analyzes involved both descriptive measures and temporal trend, autocorrelation, and cross-correlation. In the meantime, the detrended fluctuation analysis (DFA) method was used to characterize this autocorrelation and identify the persistence in the time series; the cross-correlation coefficient ρDCCA, to measure the cross-correlation between the series; and the moving average, to characterize the trend. Descriptive analysis was also performed, with the estimation of the temporal trend by the linear regression model, with Prais-Winsten (PW) correction. In the period from 2000 to 2020, 16,454 hospitalizations were registered, with 3.2% for syphilis and 96.8% for HIV/AIDS. Regarding the time-based study, a persistent behavior (αDFA > 0.50) and a weak negative correlation (< 0.20) were identified between both the syphilis and the HIV/AIDS rates, and only the autocorrelation for syphilis was statistically significant. Young black people constituted most hospitalized subjects, with a general mean age of 39.2 years, with a female prevalence for syphilis (60.5%) and a male for HIV/AIDS (61.8%). The highest rates of syphilis were found in the health regions of Itabuna, Ilhéus, Paulo Afonso, and Salvador. The behavior of syphilis was statistically significant (p-value < 0.05), with an average annual percent change (AAPC) of 14.1% (ß1 > 0 and p-value < 0.05), which denotes an increasing trend. For HIV/AIDS cases, the highest rates were observed in the regions of Salvador, Camaçari, Teixeira de Freitas, and Seabra. There was no statistical significance for HIV/AIDS (p-value > 0.05), with an AAPC of 1.6% (ß1 > 0 and p-value < 0.05), which also indicates an increasing trend. We hope that, with this research, it will be possible to contribute not only to the updating of knowledge about syphilis and HIV/AIDS infection in adults, but mainly to constructing indicators, and planning and strengthening public health policies, with an emphasis on surveillance systems of the state of Bahia.
La sífilis y la infección por el virus del VIH son importantes problemas de salud pública, dadas las altas tasas de morbimortalidad y el impacto que llevan a los programas y políticas de salud pública, tanto de forma aislada como en relación con la coinfección. Si bien la sífilis es una enfermedad curable y el VIH/sida, una enfermedad tratable, ambas han afectado a millones de personas en el mundo, y en Brasil destaca el estado de Bahía por sus altas tasas de infección. Este cuadro se intensifica aún más cuando se observan las notificaciones según raza/color de piel, en que hay un gran número de casos entre jóvenes negros. Esta tesis pretende analizar la dinámica espaciotemporal de las tasas de hospitalización por sífilis y VIH/sida en adultos, en las regiones de salud de Bahía (Brasil), en el período de 2000 a 2020. Los datos provienen del Sistema de Información Hospitalaria (SIH) que dispone el Departamento de Informática del Sistema Único de Salud (DATASUS); mientras que los datos de población y raza/color de piel se obtuvieron del Instituto Brasileño de Geografía y Estadística (IBGE). Los análisis incluyeron medidas descriptivas y tendencias temporales, autocorrelación y correlación cruzada. Por su parte, se realizó el método detrended fluctuation analysis (DFA) para caracterizar esta autocorrelación e identificar la persistencia en la serie temporal; el coeficiente de correlación cruzada ρDCCA para medir la correlación cruzada entre las series, así como la media móvil para caracterizar la tendencia. También se realizó un análisis descriptivo, con la estimación de la tendencia temporal mediante el modelo de regresión lineal, con corrección de Prais-Winsten (PW). De 2000 a 2020 se registraron 16.454 hospitalizaciones, el 3,2% por sífilis y el 96,8% por VIH/sida. En cuanto al estudio de base temporal, se identificó un comportamiento persistente (αDFA > 0,50) y una correlación negativa débil (< 0,20) tanto entre las tasas de sífilis como de VIH/sida, y solo es estadísticamente significativa la autocorrelación por sífilis. Los jóvenes negros son mayoría entre los individuos hospitalizados, cuyo promedio general de edad es de 39,8 años, con predominancia de mujeres con sífilis (60,5%) y de varones con VIH/sida (61,8%). Las mayores tasas de sífilis se encontraron en las regiones sanitarias de Itabuna, Ilhéus, Paulo Afonso y Salvador. El comportamiento de la sífilis fue estadísticamente significativo (p-valor < 0,05), con una variación porcentual anual (VPA) del 14,1% (ß1 > 0 y p-valor < 0,05), lo que apunta a una tendencia creciente. Para los casos de VIH/sida, las tasas más altas se observaron en las regiones de Salvador, Camaçari, Teixeira de Freitas y Seabra. No hubo significación estadística para el VIH/sida (p-valor > 0,05), con un VPA del 1,6% (ß1 > 0 y p-valor < 0,05), lo que también indica una tendencia creciente. Se espera que con esta investigación se pueda contribuir no solo a la actualización de conocimientos sobre la infección por sífilis y VIH/sida en adultos, sino principalmente a la construcción de indicadores, planificación y fortalecimiento de políticas públicas de salud, con énfasis en los sistemas de vigilancia en el estado de Bahía.
