RESUMEN
Introducción: durante las últimas dos décadas, el concepto de capital social se ha utilizado con creciente frecuencia en las ciencias de la salud debido a las relaciones directas e indirectas entre el capital social y la salud física y mental de las poblaciones. Por tanto, es necesario construir un instrumento para cuantificar este concepto con seguridad y confiabilidad. Objetivo: analizar la consistencia interna y dimensionalidad de una escala de siete ítems para medir el capital social en adultos de la población general de Colombia. Metodología: se realizó un estudio de validación en línea, que incluyó una muestra de 700 adultos de entre 18 y 76 años, el 68 % eran mujeres. Los participantes completaron una escala de siete ítems llamada Escala de Capital Social Cognitivo (ECSC). El alfa de Cronbach y el omega de McDonald se calcularon para probar la consistencia interna. Se realizaron análisis factoriales exploratorios y confirmatorios para explorar la dimensionalidad de la ECSC. Resultados: la ECSC presentó una consistencia interna baja (alfa de Cronbach de 0,56 y omega de McDonald de 0,59) y pobre dimensionalidad. Seguidamente, se probó una versión de cinco ítems (ECSC-5). La ECSC-5 mostró una alta consistencia interna (alfa de Cronbach de 0,79 y omega de McDonald de 0,80) y una estructura unidimensional con indicadores de bondad de ajuste aceptables. Discusión: la ECSC-5 presenta alta consistencia interna y una estructura unidimensional para medir el capital cognitivo social en adultos colombianos. Se recomienda la ECSC-5 para la medición del capital social en la población general colombiana. Futuras investigaciones deben corroborar estos hallazgos en aplicaciones de lápiz y papel y explorar otros indicadores de confiabilidad y validez.
Introduction: During the last two decades, the concept of social capital has been used increasingly frequently in health sciences due to the direct and indirect relationships between social capital and populations' physical and mental health. Therefore, it is necessary to build an instrument to quantify this concept confidently and reliably. Objective: The study aimed to internal consistency and dimensionality of a seven-item scale to measure social capital in Colombia's general population of adults. Methods: An online validation study included a sample of 700 adults aged between 18 and 76 years; 68% were females. Participants completed a seven-item scale called the Cognitive Social Capital Scale (CSCS). Cronbach's alpha and McDonald's omega were computed to test internal consistency. The authors explore the internal consistency and dimensionality of the CSCS. Results: The CSCS presented a low internal consistency (Cronbach's alpha of 0.56 and McDonald's omega of 0.59) and poor dimensionality. Then, the researchers tested a five-item version (CSCS-5). The CSCS-5 showed high internal consistency (Cronbach's alpha of 0.79 and McDonald's omega of 0.80) and a one-dimension structure with acceptable goodness-of-fit indicators. Discussion: The CSCS-5 presents high internal consistency and a one-dimensional structure to measure cognitive capital social in the Colombian sample. Authors can recommend measuring social capital in the general Colombian population. Further research should corroborate this pencil and paper application findings and explore other reliability and validity indicators.
RESUMEN
ABSTRACT BACKGROUND: The identification and understanding of dietary factors and other characteristics that influence gestational weight gain can contribute to the formulation of strategies to promote healthy eating habits before and during pregnancy. OBJECTIVE: To investigate the association between dietary patterns, sociodemographic and obstetric characteristics, and health-related behaviors in pregnant women. DESIGN AND SETTING: A cross-sectional study was conducted on women undergoing prenatal care in the Unified Health System of Colombo, Paraná, Brazil, from February 2018 to September 2019. METHOD: A weekly food frequency questionnaire was administered, and dietary patterns were identified through factor analysis. Median regression models were constructed to identify the associations between dietary pattern scores and variables. RESULTS: Complete data were obtained from 495 pregnant women. Three dietary patterns were identified: 1) "healthy," with higher factor loadings for the weekly consumption of raw vegetables, cooked vegetables, and fresh fruits; 2) "Western," including soft drinks or artificial juice, candies, milk, and dairy products, and processed cold meat; and 3) "traditional," beans and meat. Pregnant women aged 30 years or older (coefficient [Coef.] 0.86, 95% confidence interval [CI] 0.38-1.33) with moderate/intense physical activity (Coef. 0.32, 95% CI 0.02-0.62) had higher adherence to the "healthy" pattern. Adolescents and smokers adhered more to the "traditional" pattern (Coef. 0.17, 95% CI 0.01-0.33). CONCLUSION: Age, smoking status, and physical activity were associated with dietary patterns in pregnant women.
RESUMEN
Objective:To investigate the influential factors of patients' expectations for clinical decision-making during digestive endoscopy.Methods:A total of 120 patients who underwent digestive endoscopy were admitted to the Endoscopy Center of Zhejiang Provincial People's Hospital from January 2020 to January 2022. Their general information was collected, and their clinical decision-making expectations were evaluated using the Control Preference Scale (CPS). The influential factors of clinical decision-making expectations were determined using multiple linear regression analysis.Results:The total CPS score for 120 patients undergoing digestive endoscopy was (50.72 ± 5.48) points, including (14.12 ± 1.48) points for information needs, (25.17 ± 3.52) points for communication needs, and (11.43 ± 2.04) points for decision-making needs. Univariate analysis showed that the CPS score of patients undergoing digestive endoscopy was related to gender, age, marital status, educational level, number of children, and type of visit ( t = 2.68, 2.61, 2.82, 3.28, 3.61, 2.39, all P < 0.05). Multiple linear regression analysis showed that gender, age, educational level, and type of visit were the influential factors of clinical decision-making expectations for patients undergoing digestive endoscopy ( β = -0.71, 1.07, 0.53, -1.15, all P < 0.05). Conclusion:Gender, age, educational level, and type of visit are influential factors of patients' expectations for clinical decision-making during digestive endoscopy. Patients have a clear need for communication during clinical decision-making, and medical staff can strengthen communication with patients, correctly guiding them to participate in clinical decision-making expectations.
RESUMEN
Objective:To investigate the incidence and risk factors of ultrafiltration failure (UFF) in patients undergoing continuous ambulatory peritoneal dialysis (CAPD).Methods:The clinical data of 65 patients undergoing CAPD at the Hubei Provincial Corps Hospital of Chinese People's Armed Police Forces and the General Hospital of Central Theater Command from January 2016 to December 2021 were retrospectively analyzed. The clinical data included patient history, smoking history, duration of peritoneal dialysis, incidence of peritonitis, levels of hemoglobin, albumin, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol, and triglyceride. Univariate and multivariate regression analyses were conducted to investigate the correlation between UFF and various indicators in patients undergoing CAPD.Results:Among the 65 patients undergoing CAPD, the incidence of UFF was 35.4% (23/65). There were significant differences in duration of peritoneal dialysis, history of peritonitis, history of type 2 diabetes mellitus, serum albumin, low-density lipoprotein cholesterol, and triglyceride between patients with UFF and those without UFF ( t = -5.05, χ2 = 11.51, 6.83, t = 5.91, -3.28, -2.83, all P < 0.05). Multivariate regression analysis showed that albumin was negatively correlated with UFF ( r = -1.06, P < 0.05), while duration of peritoneal dialysis, level of low-density lipoprotein cholesterol, and peritonitis were positively correlated with UFF ( r = 0.43, 2.20, 1.67, all P < 0.05). Conclusion:Peritoneal dialysis duration, peritonitis, and low-density lipoprotein cholesterol are risk factors for UFF in patients undergoing CAPD, while albumin is a protective factor against UFF in these patients.
RESUMEN
Objective:To investigate the risk factors for recurrence of benign vocal cord lesions after microsurgery.Methods:The clinical data of 2 214 patients with benign vocal cord lesions who underwent laryngeal microsurgery at the Department of Otolaryngology-Head and Neck Surgery, Affiliated Hospital of Yangzhou University from April 2013 to April 2022 were collected. The data, including sex, age, drinking history, smoking history, unilateral and bilateral lesions, and diagnosis, were recorded. These patients were divided into six groups according to admission diagnosis: polyps, Reinke's edema, leukoplakia, granulomas, cysts, and other benign lesions. All patients were followed up for 0-115 months, with a median follow-up time of 55 months. The Kaplan-Meier curve was used to determine whether there was any difference in the recurrence rate of benign vocal cord lesions among groups after surgical treatment. The Cox regression model was used to analyze the risk factors for the recurrence of benign vocal cord lesions after surgical treatment.Results:Out of the 2 214 patients, there were 1 953 cases of polyps (88.21%), 41 cases of granulomas (1.85%), 67 cases of cysts (3.03%), 87 cases of leukoplakia (3.93%), 34 cases of Reinke's edema (1.54%), and 32 cases of other benign lesions (1.45%). The recurrence rate for benign vocal cord lesions was 4.86% (95/1 953) in the polyp group, 31.70% (13/41) in the granuloma group, 14.94% (13/87) in the leukoplakia group, 2.98% (2/67) in the cysts group, 8.82% (3/34) in the Reinke's edema group, and 9.37% (3/32) in the other benign lesions group. Univariate analysis showed that bilateral lesions (95% CI 6.899-17.289, P < 0.001), smoking history (95% CI 1.282-2.564, P = 0.001), and alcohol consumption (95% CI 1.173-2.346, P = 0.001) were significantly associated with the recurrence of benign vocal cord lesions. The recurrence rate for benign vocal cord lesions in the leukoplakia group (95% CI 1.375-27.011, P = 0.017) and granuloma group (95% CI 3.053-60.980, P = 0.001) was significantly higher than that in the cysts group. Multivariate analysis of the risk factors for postoperative recurrence of benign vocal cord lesions showed that patients who had bilateral lesions (95% CI 6.680-16.900, P < 0.001) and a history of smoking (95% CI 1.572-16.157, P = 0.007) had a higher risk of recurrence of benign vocal cord lesions compared with those without bilateral lesions and a history of smoking. Granulomas were found to be significantly associated with postoperative recurrence of benign vocal cord lesions (95% CI 4.691-97.667, P < 0.05). Conclusion:Bilateral lesions and smoking are independent risk factors for the recurrence of benign vocal cord lesions after microsurgery. Granuloma is strongly associated with the postoperative recurrence of benign vocal cord lesions.
RESUMEN
Objective:To investigate electrocardiogram (ECG) characteristics and related factors of gestational diabetes mellitus (GDM) complicated by depressive disorder.Methods:The clinical data of 243 patients with GDM who received treatment at Peking University Third Hospital from September 2021 to December 2022 were retrospectively analyzed. According to the scoring results of the Self-rating Depression Scale (SDS), these patients were divided into an observation group (GDM + depressive disorder, n = 51) and a control group (GDM alone, n = 192). The χ2 test was used to analyze the relationship between GDM complicated by depressive disorder and ECG diagnosis results. Additionally, the t-test was used to compare ECG indicators between the two groups. Results:Compared with the control group, patients in the observation group had a higher incidence of abnormal ECG indicators, including bradycardia ( χ2 = 4.68, P = 0.030), premature contraction ( χ2 = 10.78, P = 0.001), and atrioventricular block ( χ2 = 15.04, P < 0.001). However, there were no significant differences in the incidences of tachycardia, bundle branch block, or ST-T changes between the two groups (all P > 0.05). Compared with the control group, the observation group exhibited significantly increased heart rate [(73.43 ± 8.24) beats/min vs. (67.22 ± 5.08) beats/min], maximum QT interval [(419.09 ± 36.00) ms vs. (351.95 ± 32.07) ms], minimum QT interval [(363.31 ± 30.78) ms vs. (316.52 ± 29.10) ms], and QT dispersion [(55.78 ± 17.87) ms vs. (35.42 ± 13.18) ms, t = -5.13, -12.95, -10.08, -7.60, all P < 0.001]. Conclusion:Among patients with gestational diabetes mellitus, those with depressive disorder have an increased risk of exhibiting abnormal electrocardiogram patterns compared with those without depressive disorder.

RESUMEN
Objective:To test the reliability and validity of the general procrastination scale (GPS) in the application of middle school students.Methods:The Chinese version of GPS, the irrational procrastination scale(IPS), and the Maslach burnout inventory(MBI) were utilized to survey 10 825 middle school students in Harbin City through stratified random sampling, and 4 498 students were retested after 4 weeks. Statistical analysis was performed using SPSS 27.0 and Mplus 8.0.Results:The entries were well differentiated.Exploratory and confirmatory factor analysis indicated that GPS was composed of two factors, including active avoidance and lack of planning.The model fit was good (CFI=0.914, TLI=0.901, RMSEA=0.069, SRMR=0.072). GPS was positively correlated with the total scores of IPS and MBI ( r=0.753, 0.677, both P<0.001). The Cronbach's α coefficient of GPS was 0.864, the folded half reliability was 0.870, and the retest reliability after 4 weeks was 0.756. Conclusion:The GPS has good reliability and validity among middle school students, which provides a standard for measuring the procrastination level of middle school students and carrying out related research.
RESUMEN
Objective To investigate the recurrence of immune thrombocytopenia(ITP)in children and to establish a predictive model.Methods A total of 288 children with ITP admitted to Children's Hospital of Wujiang District and Children's Hospital Affiliated to Suzhou University from January 2018 to April 2022 were collected.The factors potentially related to the recurrence of ITP in children were screened.The children in the model group were divided into 2 groups according to the presence or absence of recurrence and the indicators of the 2 groups were compared.After screening the potential influencing factors by LASSO regression and the independent influencing factors of relapse in children with ITP patients by Logstic regression analysis,we constructed a column-line graph model by using R language and validated it.Results A total of 37(18.47%)of 201 patients in the model group experienced relapse.The age,blood type,duration of disease before treatment,antecedent infections,bleeding,initial treatment regimen,antinuclear antibody titer,initial count and mean platelet volume,initial platelet distri-bution width,initial peripheral blood lymphocyte count and time length to effective platelet count after treatment were found in the recurrence group versus the non-recurrence group The difference was statistically significant(P＜0.05).The results of multifactorial logistic regression analysis performed on the basis of LASSO regression showed that blood type,duration of illness before treatment,antecedent infection,initial treatment regimen,ini-tial peripheral blood lymphocyte count,and time to effective platelet count after treatment were independent influ-ences on the conversion of cough variant asthma to classic asthma in children.Based on the results of the multifac-torial analysis,a column chart model for predicting ITP recurrence in children was developed in R.The results of the receiver operating characteristic(ROC)analysis showed that the area under curve(AUC)of the column chart model for predicting ITP recurrence in children in the modeling group was 0.867[95%CI(0.796,0.938)]with a sensitivity of 84.2%and a specificity of 73.1%,and that in the validation group,the AUC was 0.838[95%CI(0.765),0.911]with a sensitivity of 82.3%and a specificity of 78.4%,0.911)]sensitivity was 82.3%and specificity was 78.4%.The Bootstrap method was used to repeat the sampling 1000 times,and the validation group was used for validation.The results of the calibration curve showed that the prediction curves of the model group and the validation group were basically fitted with the standard curve,suggesting that the model prediction accuracy was high.The results of the decision curve analysis of the model group showed that the net benefit rate of patients was greater than zero when the probability threshold of the column line graph model of pre-dicting ITP recurrence in children was 0.15-0.75.Conclusions ITP recurrence in children is mainly affected by the patient's age,blood type,and pre-treatment course of the disease,and the column-line diagram model based on these factors has a high accuracy and differentiation for ITP recurrence in parenting children.
RESUMEN
Objective To construct a risk prediction model of pulmonary involvement based on chest CT and clinical feature in patients with primary Sjogren's syndrome(pSS),and to explore the risk prediction value of the model.Methods A total of 360 pSS patients who had been treated at Handan Hospital of Traditional Chinese Medicine from October 2020 to August 2023 were retrospectively selected as study objects,and were then divided into a modeling group(252 patients)and a verification group(108 patients)according to a ratio of 7∶3.The patients in the modeling group were divided into a control group(201 patients)and an involvement group(51 patients)based on presence or absence of lung involvement.The data on clinical characteristics and features of chest high-resolution CT(HRCT)in the modeling group was collected.Univariate analysis was performed among the groups to determine the relevant factors affecting lung involvement in pSS patients.Binary logistic regression analysis was performed on related factors to screen independent risk factors.A prediction model was established based on the independent risk factors.A verification and value analysis of the column-line prediction model were completed through data collection of the verification group.Results Age,disease course,cough,Raynaud's phenomenon,C-reactive protein(CRP),anti-SSA antibody,and HRCT were the relevant factors affecting lung involvement in pSS patients(all P＜0.05).Further binary logistic regression analysis showed that old age,prolonged disease course,cough and abnormal HRCT imaging were independent risk factors for lung involvement in SS patients(all P＜0.05).A nomogram risk prediction model was constructed based on independent factors.The model verification results indicated that the calibration chart showed better performance in the prediction model.The AUC of the area under the receiver operating characteristic(ROC)curve was 0.993 the modeling group and 0.995 in the validation group.Conclusions The clinical characteristics and the results of chest CT are closely related with lung involvement in patients with pSS.Old age,prolonged disease course,cough,and abnormal HRCT imaging are independent risk factors affecting lung involvement in patients with pSS.The prediction model established on this basis has a higher predictive value for the occurrence of lung involvement in patients receiving after-loading radiotherapy.
RESUMEN
BACKGROUND:Anterior cruciate ligament avulsion fracture at tibial insertion is a special type of intra-articular fracture,which is mostly seen in sports injuries.At present,there are relatively few anatomical studies on this disease,but a large number of studies focus on the injury of the anterior cruciate ligament.It is generally believed that the increase in the posterior slope of the tibial plateau,the decrease of the depth of the medial tibial plateau,and the decrease in the width index of the femoral intercondylar notch are the risk factors for the injury of the anterior cruciate ligament.It is unclear whether avulsion fractures of the anterior cruciate ligament at the tibial insertion point are also related to it. OBJECTIVE:To investigate the correlation between the avulsion fracture of the anterior cruciate ligament at the tibial insertion and the posterior tibial slope,the medial tibial depth,the notch width index of the femoral intercondylar fossa,and the coronal slope angle of the tibial plateau. METHODS:A retrospective analysis was made on 101 patients who were admitted to the Department of Orthopedics of Affiliated Hospital of Xuzhou Medical University due to anterior knee pain from January 2019 to December 2022.Totally 51 patients with tibial insertion avulsion fracture of anterior cruciate ligament who received arthroscopy treatment were taken as the observation group,and 50 patients with anterior knee pain but no knee joint injury confirmed by physical examination and imaging examination were taken as the control group in the same period.The posterior tibial slope,anatomical parameters such as the medial tibial depth,and the notch width index of the femoral intercondylar fossa,were statistically analyzed for the anatomical risk factors leading to the tibial insertion avulsion fracture of the anterior cruciate ligament. RESULTS AND CONCLUSION:(1)There was no significant difference between the two groups in the comparison of the lateral posterior tibial slope,the posterior slope ratio of the lateral/medial tibial plateau,the notch width index of the femoral intercondylar fossa,and the coronary slope angle of the tibial plateau(P>0.05).The medial posterior tibial slope in the observation group was significantly higher than that in the control group(P<0.05).The medial tibial depth in the observation group was significantly lower than that in the control group(P<0.05).(2)Multifactor logistic regression analysis showed that the medial posterior tibial slope and the medial tibial depth were independent risk factors for tibial insertion avulsion fracture of anterior cruciate ligament(P<0.05).(3)The receiver operating characteristic curve shows that the medial posterior tibial slope and the medial tibial depth had certain predictive values for the tibial insertion avulsion fracture of the anterior cruciate ligament.(4)It is indicated that the increased medial posterior tibial slope and the shallower medial tibial depth are the anatomical risk factors for the avulsion fracture of the tibial insertion of the anterior cruciate ligament.
RESUMEN
BACKGROUND:Cervical rotatory manipulation is widely used in the treatment of neck-related diseases with a clear curative effect,but it also has some risks in clinical practice.The previous study of our group found that cervical rotatory manipulation can reduce the tensile mechanical properties of the atherosclerotic carotid artery,but it is not clear about the effects of different cervical rotatory manipulations(positioning/non-positioning)and different degrees(mild/moderate/severe)of atherosclerosis on the tensile mechanical properties of the carotid artery. OBJECTIVE:To explore the effects of different cervical rotatory manipulations and different degrees of atherosclerosis on the tensile mechanical properties of the internal carotid artery. METHODS:The 120 male New Zealand rabbits were randomly divided into eight experimental groups with different degrees of atherosclerosis and different cervical rotatory manipulations:severe atherosclerosis + positioning/non-positioning cervical rotatory manipulation,moderate atherosclerosis + positioning/non-positioning cervical rotatory manipulation,mild atherosclerosis + positioning/non-positioning cervical rotatory manipulation,and normal rabbit + positioning/non-positioning cervical rotatory manipulation,as well as three model control groups:mild/moderate/severe atherosclerosis + non-cervical rotatory manipulation,and the blank control group.Two-factor analysis of variance was used to explore the main effects and interactive effects of different cervical rotatory manipulations and different degrees of atherosclerosis on the tensile mechanical properties of the internal carotid artery.One-way analysis of variance was applied to explore the influence of different cervical rotatory manipulations on the tensile mechanical properties of the internal carotid artery under the same degree of atherosclerosis. RESULTS AND CONCLUSION:(1)Both different cervical rotatory manipulations and different degrees of atherosclerosis were the main effect factors affecting the tensile mechanical properties of the internal carotid artery.(2)For both mild and severe atherosclerosis,both positioning and non-positioning cervical rotatory manipulations reduced the maximum stress of the internal carotid artery(P<0.05)and also increased the physiological elastic modulus of the internal carotid artery(P<0.05).(3)For moderate atherosclerosis,positioning and non-positioning cervical rotatory manipulations also increased the physiological elastic modulus of the internal carotid artery(P<0.05).Non-positioning cervical rotatory manipulation reduced the maximum strain of the internal carotid artery(P<0.05),and its maximum strain was also less than the internal carotid artery of the positioning cervical rotatory manipulations(P<0.05).(4)For the normal internal carotid artery,in addition to the maximum strain,both positioning and non-positioning cervical rotatory manipulations had no statistically significant effects on other tensile mechanical indicators of the internal carotid artery(P>0.05).(5)The results suggest that both positioning and non-positioning cervical rotatory manipulations may increase the stiffness of the atherosclerotic internal carotid artery,reducing its elasticity and brittleness.Therefore,both positioning and non-positioning cervical rotatory manipulations may increase the risk of cardiovascular events in mild/moderate/severe atherosclerotic internal carotid artery,and the more severe the atherosclerosis is,the greater the risk of positioning/non-positioning cervical rotatory manipulation treatment,but the risk of positioning cervical rotatory manipulation is not lower than that of non-positioning cervical rotatory manipulation.
RESUMEN
Purpose To explore the diagnostic efficiency of ultrasound(US)combined with contrast-enhanced ultrasound(CEUS)in breast lesions and to analyze the related factors affecting the diagnostic accuracy.Materials and Methods From January 2022 to February 2023,the clinical data and ultrasound images of 784 patients who underwent breast US and CEUS examination with definite pathological results were retrospectively collected in the First Medical Center of the PLA General Hospital.The diagnostic efficacy of US combined with CEUS in benign and malignant breast lesions was analyzed,respectively.The independent risk factors for diagnostic errors were analyzed via Logistic regression.Results The sensitivity,specificity and accuracy of US combined with CEUS in the diagnosis of benign and malignant breast lesions were 89.2%,84.4%and 88.7%,respectively.The area under the receiver operating characteristic curve was 0.932.The results of multivariate Logistic regression analysis showed that the diagnosis error rate increased when the lesions were non-mass type(odds ratio,OR=1.927,P=0.047),complex cystic and solid(OR=3.729,P=0.000),and high-enhanced CEUS(OR=1.937,P=0.023),while the diagnosis error rate decreased when the lesions were large(OR=0.688,P=0.004)and with US-detect suspicious lymph node(OR=0.143,P=0.011).Conclusion When the breast lesions are non-mass type,complex cystic and solid lesions and hyper-enhancement,the diagnosis error rate of US combined with CEUS increased.It is necessary to further explore the enhancement patterns of different lesions.

RESUMEN
Objective@#To explore the pattern of change of axial length/curvatrue radius ratio (AL/CR) and associated factors in primary and secondary school students in Yunnan, so as to provide scientific basis and prospective guidance for early myopia intervention and control.@*Methods@#A total of 685 students from grades 2 to 3 and grade 7 in 2 cities/counties in Yunnan Province were selected by multi stage stratified random cluster sampling method in 2020. All the participants were followed up twice with questionnaire of myopia related factors, uncorrected distance visual acuity, and refractive parameter measurement from October,2021 and March,2023,respectivelty. The distribution and change of AL/CR in different classes and groups were analyzed, and the influencing factos of AL/CR cumulative progression were explored using generalized linear model.@*Results@#AL/CR ratio in primary school students was (2.95±0.09) at baseline, increased to (2.99±0.11) at the first follow up and (3.04±0.12) at the second follow up. AL/CR ratio in middle school students(3.08±0.13) at baseline, increased to (3.12±0.15) at the first follow up and (3.15±0.14) at the second follow up. The generalized linear model showed that after controlling for environmental factors, ethnicity ( β =-0.017) , cumulative progression of the SE ( β =-0.027) influenced the changes of AL/CR ratio among the primary school students, whereas the changes of AL/CR ratio were associated with baseline AL ( β =-0.005), baseline corneal curvatrue radius ( β =0.032) and cumulative progression of SE( β =-0.035) among middle school students ( P <0.05).@*Conclusions@#The AL/CR ratio of primary and secondary school students in Yunnan can be used to judge different refractive status types, but its variation is not only related to SE progression, but also affected by different ethnic groups and baseline ocular biological parameters. so the value of AL/CR application in assessing the progression of myopia needs to be further confirmed.
RESUMEN
Resumo A estrutura original da Escala de Satisfação no Trabalho (EST) é constituída por cinco fatores de primeira ordem (Modelo 1), correspondendo ao nível específico do construto satisfação no trabalho (ST). Contudo, estudos sugeriram duas outras estruturas, com um ou dois fatores de segunda ordem, respectivamente, nível geral (Modelo 3) e nível intermediário (Modelo 2). Este estudo testou esses três modelos estruturais para a EST, a fim de verificar qual deles apresentaria melhor ajuste. Foram analisados os dados de 200 trabalhadores que responderam à versão reduzida da EST, por meio de análise fatorial confirmatória e teste da diferença do qui-quadrado. Nos resultados, encontrou-se bom ajuste para os três modelos. Entretanto, o melhor ajuste foi para o Modelo 2, seguido dos Modelos 1 e 3. Concluiu-se que a EST pode ser utilizada para mensuração dos três níveis do constructo ST.
Abstract The original structure of the Scale of Job Satisfaction (SJS) consists of five first-order factors (Model 1), corresponding to the specific level of the job satisfaction (JS) construct. However, studies suggested two other structures, each with one or two second-order factors, representing the overall level (Model 3) and the intermediate level (Model 2) respectively. This study aimed to test these three structural models for the SJS to determine which one provided the best fit. Data from 200 workers who completed the short version of the SJS were analyzed using confirmatory factor analysis and a chi-squared difference test. The results indicated a good fit for all three models. However, Model 2 showed the best fit, followed by Models 1 and 3. It was concluded that the SJS can be used to measure the three levels of the JS construct.

RESUMEN
Abstract This study aims to present evidence for the validity of the Over-indebtedness Protection and Risk Scale (OPRIS). The instrument was constructed to assess attitudinal aspects (behavioral, cognitive, and affective) that prevent or encourage over-indebtedness, considered a serious social problem. Four hundred and forty-four adults participated in the online version. Exploratory Factor Analysis revealed the presence of two factors: protection against over-indebtedness (13 items) and risk of over-indebtedness (21 items), with good levels of adjustment. Criterion validity showed that both factors differentiated groups in terms of self-perceived stress, financial concern, presence/absence of debt, and consumption profile. OPRIS is considered to have the potential to help formulate public policies aimed at addressing the phenomenon of over-indebtedness.
Resumo O objetivo deste estudo é apresentar as evidências de validade da Escala de Proteção e Risco de Superendividamento (EPRIS). O instrumento foi construído para avaliar aspectos atitudinais (comportamentais, cognitivos e afetivos) que previnem ou estimulam o superendividamento, considerado um grave problema social. Participaram 444 adultos na modalidade online. A análise Fatorial Exploratória revelou a presença de dois fatores: proteção ao superendividamento (13 itens) e risco de superendividamento (21 itens), com bons níveis de ajuste. A validade de critério mostrou que ambos os fatores diferenciaram grupos quanto ao estresse autopercebido, preocupação financeira, presença/ausência de dívidas e perfil de consumo. Considera-se que a EPRIS tem o potencial de contribuir na formulação de políticas públicas voltadas à abordagem do fenômeno do superendividamento.
RESUMEN
Abstract Introduction The Iowa-Netherlands Comparison Orientation Measure (INCOM) was developed to measure individual differences in social comparison orientation and has been widely used in research and various different settings. Objectives The aim of this study was to adapt the online version of the INCOM and to evaluate its psychometric parameters when applied to a Brazilian population of university students. Methods The procedures were divided into two steps: step 1 - cross-cultural adaptation and analysis of content validity, and step 2 - assessment of psychometric characteristics. Step 1 comprised the processes of translation, evaluation by an expert committee, evaluation by the target population, and back-translation. For step 2, 1,065 university students were recruited and then factor analysis, analysis of reliability, and analysis of validity based on external measures were performed. Results The adaptation process yielded satisfactory results, including good indicators of content validity. Exploratory factor analysis revealed a two-dimensional structure and adequate factor loadings, except for item 11, which was excluded from the final version. Additionally, the final version of the scale had adequate fit indices (χ2 = 148.45, degrees of freedom [df] = 26; p < 0.001; root mean square error of approximation [RMSEA] = 0.06; comparative fit index [CFI] = 0.99; and Tucker-Lewis index [TLI] = 0.98). Evidence of reliability (Cronbach's alpha = 0.83) was observed and there were positive correlations with negative affect (r = 0.36) and negative correlations with positive affect and self-esteem (r = -0.15; r = -0.41, respectively). Conclusion The Brazilian version of the INCOM presents satisfactory psychometric parameters and can thus be used to measure social comparison orientation.
RESUMEN
ABSTRACT BACKGROUND AND OBJECTIVES: Neonatal pain management is considered one of the eight principles of neonatal care. This study aims to investigate the construct reflecting neonatal non-pharmacological pain management, in a Brazilian rooming-in unit, and identify the preferred intervention. METHODS: This survey study included 47 health professionals assessed through an in-person questionnaire. Factor analysis was conducted with a rotation using the Varimax method. Cronbach's alpha was 0.78. RESULTS: The construct comprised three factors in the following order: 1) knowledge and impact of neonatal pain on parents, 2) the benefits of pain treatment, and 3) non-pharmacological interventions. Breastfeeding is part of the first factor, revealing its particular importance. The reduction of luminosity is part of the second factor. Non-nutritive sucking with sweet solution, kangaroo position, and music therapy are part of the third factor. CONCLUSION: The construct observed in this rooming-in identified three factors and suggests that breastfeeding is the preferred intervention to implement for non-pharmacological pain management in the neonate.
RESUMO JUSTIFICATIVA E OBJETIVOS: O manejo da dor neonatal é considerado um dos oito princípios do cuidado neonatal. O presente estudo teve como objetivo investigar o construto que reflete o manejo não farmacológico da dor neonatal em uma unidade de alojamento conjunto brasileira e identificar a intervenção preferencial. MÉTODOS: Este estudo de pesquisa incluiu 47 profissionais de saúde avaliados por meio de um questionário presencial. A análise fatorial foi realizada com uma rotação usando o método Varimax. O alfa de Cronbach foi de 0,78. RESULTADOS: O construto foi composto por três fatores na seguinte ordem: 1) conhecimento e impacto da dor neonatal nos pais, 2) benefícios do tratamento da dor e 3) intervenções não farmacológicas. A amamentação faz parte do primeiro fator, revelando sua especial importância. A redução da luminosidade faz parte do segundo fator. A sucção não nutritiva com solução doce, a posição canguru e a musicoterapia fazem parte do terceiro fator. CONCLUSÃO: O construto observado neste alojamento conjunto identificou três fatores e sugere que o aleitamento materno é a intervenção preferencial a ser implementada para o controle não farmacológico da dor no recém-nascido.
