ABSTRACT

Abstract Introduction: Ethical culture stands out as an important variable in comprehending ethical norms and ethical behaviour at work. The Corporate Ethical Virtues (CEV) Scale is a widely used measure of ethical culture in organisations. This study aimed to adapt and validate the CEV Scale to a Brazilian context. Method: In Study 1 (n = 1.219), the CEV Scale was translated and adapted, the reliability and the internal structure were tested and the discriminant validity of ethical climate measures was demonstrated. In Study 2 (n = 635), measurement invariance in two groups was demonstrated, and there was evidence of validity based on the relationships with related constructs. Results: The results indicated that the Brazilian version of the CEV Scale showed reasonable psychometric properties and provided evidence of convergent and discriminant validity. Conclusion: This measure can be used by managers and consultants to diagnose ethical organisational culture.


Resumen Introducción: La cultura ética se destaca como una variable importante para comprender las normas y el comportamiento éticos en el trabajo. La escala de virtudes éticas corporativas (CEV) es una medida de cultura ética organizacional ampliamente utilizada. El objetivo de este estudio fue adaptar y validar la escala CEV de cultura ética al entorno brasileño. Método: En el estudio 1 (n = 1.219), la Escala CEV fue traducida y adaptada, se probaron la confiabilidad y la estructura interna y se demostró la validez discriminante de las medidas de clima ético. En el estudio 2 (n = 635), se demostró la invariancia de medición en dos grupos y hubo evidencia de validez basada en las relaciones con constructos relacionados. Resultados: Los resultados indicaron que la versión brasileña de la escala CEV mostró propiedades psicométricas razonables y proporcionó evidencia de validez convergente y discriminante. Conclusión: Esta medida puede ser utilizada por gerentes y consultores para diagnosticar la cultura organizacional ética.

ABSTRACT

Antecedentes: La irritabilidad, como síntoma transdimensional, está presente en varios trastornos mentales. Este estudio investigó las propiedades psicométricas de la versión española del Test Breve de Irritabilidad (BITe). Sujetos y métodos: el reclutamiento se realizó a través de una encuesta en línea lanzada a través de las redes sociales comunes (Facebook, Twitter) y aplicaciones de mensajería (WhatsApp, Telegram) del 1 al 31 de mayo de 2022. Los sujetos incluidos fueron personas ≥ 18 años de edad de ambos sexos 1920 individuos fueron calificados para el analisis de validacion. El BITe ha sido traducido al español y validado mediante análisis factorial confirmatorio. Los participantes también han sido puntuados con el Cuestionario de Agresión (AQ). Resultados: la prueba de Kaiser-Meyer-Olkin (KMO) fue adecuada (KMO=0,880) y la esfericidad se probó significativamente (p<0,001). El análisis confirmatorio que garantiza que la escala es unidimensional. El ajuste del modelo fue bueno, según todos los índices de ajuste. El alfa de Cronbach también garantiza una excelente consistencia interna (α=0,91). Las calculadoras entre las dos escalas (BITe y AQ) han mostrado una buena convergencia (r=0,512; p<0,001). Conclusiones: La versión en español del BITe es una escala unidimensional de cinco elementos tipo Likert que muestra buena validez interna y alta confiabilidad, lo que implica que esta versión tiene excelentes propiedades psicométricas tanto para hombres como para mujeres hispanohablantes.


Background: Irritability, as a trans dimensional symptom, is present in several mental disorders.This study investigated the psychometric properties of the Spanish version of the Brief Irritability Test (BITe). Subjects and Methods: The recruitment has been performed through an online survey launched through common social media (Facebook, Twitter) and messaging apps (WhatsApp, Telegram) from 1st to 31st May 2022. Subjects included were individuals ≥18 years old of age of both sexes. 1920 individuals were rated for the validation analysis. The BITe has been translated into Spanish and validated through confirmatory factor analysis. Participants have been also scored with the Aggression Questionnaire (AQ). Results: Kaiser-Meyer-Olkin (KMO) test was adequate (KMO=0.880) and sphericity tested significantly (p<0.001). The confirmatory analysis confirmed that the scale is one- imensional. The model adjustment was good, according to all fit indices. Cronbach's alpha also confirmed an excellent internal consistency (α=0.91). Scores between the two scales (the BITe and the AQ) have shown a good convergence (r=0.512; p<0.001). Conclusions: The Spanish version of the BITe is a unidimensional scale of five Likerttype items that shows good internal validity and high reliability, which implies that this version has excellent psychometric properties for both male and female Spanish-speakers

ABSTRACT

Resumen La autoeficacia se asocia con mejores habilidades sociales, menores niveles de agresividad y con un mejor desempeño escolar. Por este motivo, disponer de instrumentos válidos para su medición es fundamental en el ámbito escolar. El presente estudio tuvo como objetivo el análisis de las propiedades psicométricas de la Escala Multidimensional de Autoeficacia Infantil (EMA-infantil, Oros, 2017) en una muestra de 225 estudiantes ecuatorianos con una media de edad de 9.97 años. Se realizó un análisis de ítems y se encontró que el ítem 3 y el factor deportivo de la autoeficacia presentaban bajos índices de discriminación y de relación ítem-resto de la prueba. Se continuó con un análisis factorial confirmatorio en el cual se encontró que el ítem 3 no carga bien dentro del factor autoeficacia social y que los ítems de la autoeficacia deportiva presentaban bajas cargas factoriales y residuos superiores a lo esperado (RMSEA y RMSR > .07). Por ello, se analizó la posibilidad de un modelo de dos factores, sin tomar en cuenta los ítems de autoeficacia deportiva y removiendo el ítem 3, con el que se obtuvieron buenos índices de ajuste TLI = .96 y residuos RMSEA = .04, RMSR = .05. Los índices de fiabilidad para cada factor fueron: Académica = .84, Social = .85, y Deportiva = .6. Los resultados obtenidos muestran que la escala EMA es un instrumento válido en la medición de la autoeficacia académica y social. Sin embargo, no se recomienda el uso de la escala deportiva por sus pobres propiedades psicométricas.


Abstract Self-efficacy is associated with better social skills, lower levels of aggressiveness and better school performance. For this reason, having valid instruments for its measurement is essential in the school environment. The objective of this study was to analyze the psychometric properties of the Multidimensional Child Self-Efficacy Scale (EMA-infantil, Oros, 2017) in a sample of 225 Ecuadorian students with a mean age of 9.97 years. An analysis of items was performed, finding that item 3 and the sports factor of self-efficacy had low discrimination rates and item-rest of the test ratio. A confirmatory factor analysis was continued in which it was found that item 3 does not load well within the social self-efficacy factor, the items of sports self-efficacy had low factor loads and residuals higher than expected (RMSEA and RMSR > .07). Therefore, the possibility of a two-factor model was analyzed without taking into account the sport self-efficacy items and removing item 3, obtaining good adjustment indices TLI = .96 and residuals RMSEA = .04, RMSR = .05. The reliability indices for each factor were: Academic = .84, Social = .85, and Sports = .6. The results obtained show that the EMA scale is a valid instrument in the measurement of academic and social self-efficacy, however, the use of the sports scale is not recommended due to its poor psychometric properties.

ABSTRACT

Resumen El uso de instrumentos para evaluar la personalidad es una práctica común en psicología, de ahí que su validación y adaptación a diferentes grupos poblacionales sea fundamental. El objetivo de la presente investigación fue evaluar la validez de constructo del NEO Five Factor Inventory (NEO-FFI) en un grupo de 617 personas adultas mayores en Bogotá, Colombia. Se realizaron análisis factoriales confirmatorios, así como un análisis bifactorial. Los resultados mostraron que el inventario no logra un ajuste adecuado en ninguno de los modelos de primer orden, ni en el modelo bifactorial, como tampoco en el análisis de los factores por separado. Solamente, presentó un ajuste adecuado en los modelos AFC modificados que evalúan cada factor como individual, a excepción del factor Amabilidad. Precisamente, los ítems que tuvieron bajas cargas factoriales son aquellos ítems negativos o reversos, y, dado que la comprensión de este tipo de ítems requiere de mejores habilidades lingüísticas, se infiere que el bajo nivel educativo de las personas que conformaron la muestra pudo interferir en el logro de un ajuste adecuado de los modelos; en consecuencia, se recomienda estudiar este aspecto en futuras investigaciones.


Abstract The use of instruments to assess personality is a common practice in psychology, therefore its validation and adaptation to different population groups is fundamental. The aim of the current research was to evaluate the construct validity of the NEO-FFI Inventory in a group of 617 elderly people in Bogotá, Colombia. First ordered confirmatory factor analyses and bi-factor models were performed. The results showed that the Inventory does not achieve an adequate adjustment in any of the first-order models, nor in the bi-factorial model, nor in the analysis of the factors separately. Only in the modified CFA models that evaluate each factor individually, with the exception of Agreeableness, an adequate fit was achieved. The items registering low factor loadings are especially those negative or reverse items, and since the understanding this type of items requires better linguistic skills, it is inferred that the low educational level of the sample could interfere in achieving an adequate adjustment of the models. Consequently, it is recommended to study this aspect in future research.

ABSTRACT

RESUMO Objetivo A qualidade de vida sexual abarca a satisfação sexual e com a parceria, a expressão de desejos e valores sexuais, a boa imagem corporal, além de questões de ordem física, comportamentais, psicológicas e emocionais que afetam a sexualidade. Não há instrumentos confiáveis e válidos para avaliar a qualidade de vida sexual das mulheres brasileiras, portanto este estudo buscou traduzir o Questionnaire on Sexual Quality of Life - Female (SQoL-F) e apresentar evidências de validade do instrumento no contexto brasileiro. Métodos Foram realizados tradução, avaliação da validade de conteúdo, teste da versão pré-final e análise fatorial exploratória do instrumento. Resultados Identificou-se a presença de um único fator que explicou 49% da variância, condizente com o proposto no questionário original. Esse modelo unifatorial apresentou cargas fatoriais adequadas (entre 0,36 e 0,85). Conclusão O questionário apresentou boa consistência interna e foram apresentadas evidências de validade satisfatórias para o uso com mulheres brasileiras.


ABSTRACT Objective The quality of sexual life encompasses sexual satisfaction and with partnership, the expression of sexual desires and values, good body image, in addition to physical, behavioral, psychological and emotional issues that affect sexuality. There are no reliable and valid instruments to assess the quality of sexual life of Brazilian women, so this study sought to translate the Questionnaire on Sexual Quality of Life - Female (SQoL-F) and present evidence of validity of the instrument in the Brazilian context. Methods The translation, content validity evaluation, pre-final version test and exploratory factor analysis were performed. Results The presence of a single factor was identified that explained 49% of the variance, consistent with what was proposed in the original questionnaire. This one-factor model presented adequate factor loadings (between 0.36 and 0.85). Conclusion The questionnaire had good internal consistency and presented satisfactory evidence of validity for use with Brazilian women.

ABSTRACT

SUMMARY OBJECTIVE: This study aimed to validate the internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire. METHODS: A cross-sectional study was conducted with individuals over 18 years old of both sexes, with Brazilian Portuguese as their native language. The structure of the Baecke Habitual Physical Activity Questionnaire was tested by confirmatory factor analysis. The model fit was evaluated by the following indices: root mean square error of approximation, comparative fit index, Tucker-Lewis index, standardized root mean square residual, and χ²/degrees of freedom. We used the Akaike information criterion and Bayesian information criterion to compare different structures of the Baecke Habitual Physical Activity Questionnaire. RESULTS: A total of 241 individuals participated in this study. The original structure of the Baecke Habitual Physical Activity Questionnaire with 16 items and 3 domains was compared to a structure with 14 items and 3 domains. The internal structure of the Baecke Habitual Physical Activity Questionnaire with 14 items showed better fit indices and lower Akaike information criterion and Bayesian information criterion values. CONCLUSION: The best internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire in adults presents 3 domains and 14 items.

ABSTRACT

Resumen El propósito del presente estudio es examinar la validez de constructo y consistencia interna del Inventario Peruano de Mindfulness y Ecuanimidad. Basado en el análisis factorial y la Teoria de Respuesta al Item (Modelo de Crédito Parcial y el Método de Escalabilidad de Mokken), se examinó la magnitud de los parâmetros y se estimò la varianza de cada uno de los items para contribuir en el constructo general de mindfulness. La muestra del estudio está compuesta por 602 adultos, estudiantes de tres instituciones acadêmicas de educación superior de Lima, Chiclayo y Chimbote en el Perú. Los resultados de estos análisis indican una estructura unidimensional del instrumento, en función a ocho items representados por los atributos de atención, consciencia, aceptación, juicio de valor, y ecuanimidad. Los indicadores de ajuste del modelo de factores oblicuos para los items seleccionados fueron satisfactorios: CEI = .982, RMSEA = .043 (IC90% = .029, .056), SRMR = .048, SB--2 (gl: 35) = 73.415 (p > 0.05).


Abstract The main purpose of this study is to report the construct validity and internal consistency of the Peruvian Inventory of Mindfulness and Equanimity. Based on the factor analysis and the Item response Theory (the Partial Credit Model and the Mokken Scale Analysis), the parameters magnitude was examined, and we estimated the variance of each item of the instrument that contribute to the general construct of mindfulness. The analyses were carried out on a sample of 602 adults, students from three educational institutions at the university level in the cities of Lima, Chiclayo, and Chimbote in Peru. The results of all the analyses performed on this peruvian sample suggest a unidimensional structure of this inventory, based on the eight items selected that include the abilities of attention, consciousness, acceptance, judgment, and equanimity. The goodness of fit index and adjusted goodness of fit index for the oblique factors were satisfactory: CEI = .982, RMSEA = .043 (lC90% = .029, .056), SRMR = .048, SB- -2 (gl: 35) = 73.415 (p > 0.05).

ABSTRACT

This study aimed to develop the Age Diversity Management in Organizations scale for the Brazilian context and verify its evidence of validity. The process included five steps: proposal of its definition and development of the items according to the literature; content and semantic validity by judges; semantic validity by the target population; exploratory factorial analysis (EFA); and confirmatory factorial analysis (CFA). The EFA sample consisted of 674 workers from different organizations and the CFA of 722 workers. The final version of the scale was composed of 20 items (α =.91), divided into four factors: retirement preparation practices (5 items, α =.93); equal treatment for workers of different ages (6 items, a=.85), training to promote age diversity (5 items, α =.81), and management practices for older workers (4 items, α =.72). The theoretical and practical implications as well as the limitations of this measure are discussed. (AU)

ABSTRACT

Resumen El daño ambiental que se ha venido provocando a causa de la actividad humana es preocupante, razón por la cual se ha identificado como una de las posibles soluciones tener un comportamiento proambiental. Sin embargo, se ha visto que hay barreras psicológicas que impiden o dificultan esta conducta. Por este motivo, con el fin de tener un instrumento que permita evaluar estas barreras psicológicas en nuestro contexto, el objetivo de la presente investigación fue realizar la adaptación de la escala Dragons of Inaction Psychological Barriers (DIPB) en población colombiana. La muestra estuvo compuesta por 810 estudiantes universitarios de Bogotá y Chía, Colombia; 367 hombres y 443 mujeres con edades entre los 15 y los 48 años (M = 19.67, DE = 2.414). En general, se realizó un análisis factorial exploratorio y un análisis factorial confirmatorio, con los cuales se comprobó la existencia de una estructura de cinco factores con 20 ítems; se realizaron análisis de reactivos y fiabilidad que demostraron que el instrumento tiene una alta consistencia interna; y se llevaron a cabo dos estudios de invarianza, con los que se demostró que la estructura factorial es invariante para todos los grupos de estudio. Además, se realizó la baremación del instrumento total. En conclusión, esta adaptación del DIPB presenta adecuada validez y fiabilidad, y permite guiar futuras investigaciones acerca de las barreras de inacción en el contexto latinoamericano, a la vez que aporta un insumo para realizar un primer diagnóstico de este constructo en Colombia.


Abstract The environmental damage that has been generated by human activity is a cause for concern, so pro-environmental behavior has been identified as one of the possible solutions. However, it has been seen that there are psychological barriers that prevent or hinder this behavior. For this reason, in order to have an instrument to evaluate these psychological barriers in our context, the objective of this research was to adapt the Dragons of Inaction Psychological Barriers (DIPB) scale to the Colombian population. The sample was made up of 810 university students from Bogotá and Chía, Colombia; 367 males and 443 females between 15 and 48 years of age (M = 19.67, SD = 2.414). In general, an exploratory factor analysis and a confirmatory factor analysis were carried out, which demonstrated the existence of a five-factor structure with 20 items. Item and reliability analyses were performed, which demonstrated that the instrument has a high internal consistency; and two invariance studies were carried out, which showed that the factor structure is invariant for all study groups. In addition, the total instrument was scored. In conclusion, this adaptation of the DIPB presents adequate validity and reliability, and allows guiding future research on inaction barriers in the Latin American context, while providing an input for a first diagnosis of this construct in Colombia.

ABSTRACT

Objectives: Although the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a widely used instrument for assessing different obsessive-compulsive symptom dimensions, its factor structure has never been studied in a Brazilian population. Thus, we aimed to assess the goodness-of-fit indexes and factor loadings of two higher-order models of the DY-BOCS using confirmatory factor analysis (CFA) in a large obsessive-compulsive disorder (OCD) sample. Methods: We tested two CFA models in a sample of 955 adults with OCD who had been assessed with the DY-BOCS in a cross-sectional multi-site study. The first model encompassed the symptom checklist (present or absent), whereas the second focused on items related to severity scores. Results: Both models presented adequate goodness-of-fit indexes. The comparative fit index, Tucker-Lewis index, and omega were > 0.9, while the root mean square error of approximation was ≤ 0.06 for both models. Factor loadings for each item of each dimension are presented and discussed. Conclusion: Higher-order factor models showed adequate goodness-of-fit indexes, indicating that they appropriately measured OCD dimensions in this Brazilian population.

ABSTRACT

OBJECTIVE@#To investigate the expression of aldehyde dehydrogenase 3B1 (ALDH3B1) in gastric cancer and explore its correlation with the pathological parameters and long-term prognosis of the patients.@*METHODS@#We analyzed the clinical data of 101 patients who underwent radical gastrectomy for gastric cancer in our hospital between January, 2013 and November, 2016, and examined the expression of ALDH3B1 in paraffin-embedded samples of gastric cancer tissues and adjacent tissues from these cases by immunohistochemical staining. We evaluated the correlation between ALDH3B1 expressions and histopathological parameters and assessed the predictive value of ALDH3B1 expression for long-term survival of the patients. We also examined the effect of lentivirus-mediated interference and overexpression of ALDH3B1 on the malignant behaviors of MGC-803 gastric cancer cells.@*RESULTS@#The expressions of ALDH3B1 and Ki67 were significantly higher in gastric cancer tissues than in adjacent tissues (P < 0.05). In gastric cancer patients, ALDH3B1 expression was positively correlated with peripheral blood CEA and CA19-9 levels (P < 0.01). The proportion of patients with CEA ≥5 μg/L, CA19-9 ≥37 kU/L, T stage of 3- 4, and N stage of 2-3 was significantly greater in high ALDH3B1 expression group than in low expression group. Kaplan-Meier survival analysis showed that the 5-year survival rate was significantly lower in gastric cancer patients with high ALDH3B1 expressions (P < 0.01). Univariate and Cox multiple regression analyses identified a high expression of ALDH3B1 (P < 0.05, HR= 0.231, 95% CI: 0.064-0.826), CEA≥5 μg/L (P < 0.01, HR=4.478, 95% CI: 1.530-13.110), CA19-9≥37 kU/L (P < 0.01, HR=3.877, 95% CI: 1.625-9.247), T stage of 3-4 (P < 0.01, HR=4.953, 95% CI: 1.768-13.880), and N stage of 2-3 (P < 0.05, HR=2.152, 95% CI: 1.152-4.022) as independent risk factors affecting 5-year survival after radical gastrectomy. The relative ALDH3B1 expression level, at the cut-off point of 4.66, showed a sensitivity of 76.47% and a specificity of 76% for predicting 5-year postoperative death (P < 0.01). In the cell experiment, overexpression of ALDH3B1 obviously promoted the proliferation, migration and invasion of MGC-803 cells.@*CONCLUSION@#As an independent risk factor affecting 5-year survival after radical gastrectomy, ALDH3B1 is highly expressed in gastric cancer and correlated with pathological parameters of the tumor, and a high ALDH3B1 expression may promote proliferation, invasion and metastasis of gastric cancer cells.

ABSTRACT

ObjectiveTo explore the common syndromes of patients with cerebral infarction in rural areas of eastern Henan based on latent structure model and factor analysis,and provide reference for clinical differentiation of cerebral infarction. MethodThe data samples of patients with cerebral infarction in rural areas in eastern Henan were preprocessed. With Lantern 5.0 of latent structure method and LTM-EAST algorithm of two-step latent tree analysis, the manifest variable latent structure model of related symptoms was built to interpret different latent nodes, and common syndromes of cerebral infarction were obtained via comprehensive cluster analysis. SPSS 20.0 was used for factor analysis and cluster analysis of related symptoms to infer the distribution of syndrome types. ResultThe data of 888 patients with cerebral infarction were included, involving symptoms, tongue and pulse (88 in total). The 65 symptoms with a frequency of ≥5% were constructed into a latent structure model, and 31 latent variables were obtained. The Bayesian information criterion (BIC) score was -15 367.17. Based on professional knowledge, s6 common syndrome types were found, namely, syndrome of upward disturbance of wind-fire, Qi deficiency and blood stasis syndrome, syndrome of phlegm and blood stasis blocking collaterals, syndrome of phlegm-heat and fu-organ excess, syndrome of wind phlegm obstructing collaterals, and syndrome of stirring wind due to yin deficiency. In factor analysis, the symptoms with a frequency of >10% were selected, and 13 common factors were obtained and used for systematic cluster analysis. And 5 syndrome types were inferred: syndrome of wind phlegm obstructing collaterals, syndrome of phlegm-heat and fu-organ excess, Qi deficiency and blood stasis syndrome, syndrome of combined phlegm and blood stasis, and syndrome of yin deficiency and internal heat. According to the determination criteria of syndrome types in traditional Chinese medicine (TCM), 6 common syndrome types of cerebral infarction were finally determined. ConclusionAccording to the severity of the disease, the common syndromes of patients with cerebral infarction in rural areas of Eastern Henan were divided into the following categories: apoplexy involving channel and collateral: syndrome of upward disturbance of wind fire, syndrome of wind phlegm obstructing collaterals, and syndrome of stirring wind due to yin deficiency. Apoplexy involving zang and fu-viscera: syndrome of phlegm-heat and fu-organ excess, and syndrome of phlegm and blood stasis blocking collaterals. Recovery period: Qi deficiency and blood stasis syndrome. This study was basically consistent with the syndrome law in TCM theory, and provided reference for further establishing syndrome diagnostic criteria of cerebral infarction.

ABSTRACT

Objective:To understand the needs, problems and challenges of medical personnel in the hospital for scientific research, propose tailored management measurements and suggestions for the hospital.Methods:The questionnaire was prepared by " Questionnaire Star" , the convenience sampling method was used, and information was collected by WeChat online chat group. Factor analysis and multi-dimensional preference analysis were adopted to analyze information collected.Results:Four main factors that affect the scientific research of medical personnel were identified. The most significant impact is the lack of information platform, followed by the lack of environmental atmosphere, lack of personal capacity and lack of personal interest. The research needs of medical personnel are divided into two categories: one is the more basic skill needs, which are mainly targeted at female, nurses, undergraduates, 5~10 years′ working experiences, medium-grade professional title, and people with no knowledge and experience in research. The other one is the needs of skill improvement, which are mainly targeted at younger, physicians, early career, lower professional titles, and had certain research knowledge.Conclusions:So far, there is a lot of space for improvement. It is recommended to promote the capacity building by training, strengthen the research team building and construct of research communication platform, at the same time, update the scientific research management system.

ABSTRACT

Objective:To investigate the related risk factors of thrombocytopenia grade 2+ G2(+ )] in patients with gastric cancer during chemoradiotherapy.Methods:The pre-treatmentclinical data, hematologic parameters, and the correlation between dose distribution of vertebrae andTPG2(+ ) in non-metastaticgastric adenocarcinoma patients receiving concurrent chemoradiation in Sun Yat-sen University Cancer Center were retrospectively analyzed.Results:A total of 58 patients were included, including 23 cases (40%) in theTPG2(+ ) group and 35(60%) in the TPG2(-) group. There was no statistical difference in baseline clinical data between two groups (all P>0.05). Univariate Logistic regression analysis showed that several baseline parameters including platelet count (PLT), basophil count (BA), lactate dehydrogenase (LDH) and length of CTV (LCTV), the number of vertebrae (VBN), vertebral body volume (VBV), D max, D mean, V 5Gy, V 10Gy, V 20Gy, V 30Gy and V 40Gywere correlated with TPG2(+ )(all P<0.05). However, the multivariate Logistic regressionanalysisshowed that low PLT ( P=0.048), high LDH ( P=0.028), increased LCTV ( P=0.013), high V 20Gy/VBN ( P=0.030) were associated with the risk of TPG2(+ ). Conclusion:In gastric adenocarcinoma patients treated with chemoradiotherapy, correction of PLT reduction before treatment, avoidinglonger CTV and controlled V 20Gy correction for vertebral number may reduce significant thrombocytopenia induced by chemoradiotherapy.

ABSTRACT

Objective:To investigate the recurrence-free survival (RFS) and influencing factors of intensity-modulated radiotherapy±chemotherapy (IMRT±C) for the upper thoracic esophageal cancer.Methods:The medical records of 168 patients with cervical and upper thoracic esophageal cancer who met the inclusion criteria from January 2011 to December 2015 were retrospectively analyzed. The RFS was calculated by the Kaplan-Meier method. Multivariate prognostic analysis was performed by Cox models. The recurrence factors were identified by the Logistics model. Results:The 1-, 3-, and 5-year RFS rates were 67.8%, 38.0%, and 20.4%, respectively, and the median RFS was 21.9 months. The locoregional recurrence rate was 47.6%(80/168). The recurrence sites were local esophagus ( n=63), regional lymph nodes ( n=7), and local esophagus+ regional lymph node recurrence ( n=10). Multivariate analysis showed that hoarseness, cTstaging, combined with chemotherapy, 95%PTV 1 exposure dose and GTV average exposure dose were the influencing factors of RFS ( P=0.029, <0.001, 0.031, 0.038, 0.020). Logistics model showed that cTstaging, cNstaging, short-term efficacy, irradiationmethod, GTV maximum transverse diameter and PTV average exposure dose were the influencing factors of recurrence ( P=0.046, 0.022, 0.001, <0.001, 0.012, 0.001). Conclusions:Patients with cervical and upper thoracic esophageal cancer treated with radical IMRT combined with/without chemotherapy have a higher locoregional recurrence rate, and the recurrence rate is mainly the esophagus. The independent factors that affect RFS are different from the risk factors of recurrence.

ABSTRACT

Objective:To study the influencing factors for shoulder stiffness after rotator cuff tear.Methods:The data of 228 patients were retrospectively analyzed who had been diagnosed with rotator cuff tear by arthroscopic surgery at Department of Articular Surgery, Hospital Affiliated to Chengde Medical College from June 2019 to May 2021. Their baseline data were recorded immediately after admission, including possible risk factors for shoulder stiffness. The patients were divided into a stiffness group and a non-stiffness group based on passive range of motion of shoulder joint. Univariate and multivariate analyses were performed to find out the influencing factors for shoulder stiffness after rotator cuff tear.Results:Preliminary univariate analysis showed that advanced age, smoking history, misdiagnosis history, no standardized physiotherapy history, high body mass index (BMI) and long duration of disease were all likely risk factors for shoulder stiffness in patients with rotator cuff tear ( P<0.05). Multivariate analysis confirmed that advanced age( OR=1.474, 95% CI: 1.013~2.145, P=0.043), smoking history( OR=2.239, 95% CI: 1.147~4.368, P=0.018), no standardized physiotherapy history( OR=0.167, 95% CI: 0.065~0.424, P<0.001), high BMI( OR=3.029, 95% CI: 1.657~5.536, P<0.001) and long duration of disease ( OR=1.775, 95% CI: 1.384~2.276, P<0.001) were the risk factors for shoulder stiffness. Conclusion:Age>60 years, smoking history, misdiagnosis history, no standardized physiotherapy history, high body mass index and long course of disease may be the important influencing factors for shoulder stiffness after rotator cuff tear.

ABSTRACT

Objective:To investigate the expression of low density lipoprotein receptor associated protein 8 (LRP8) in colorectal cancer and its correlation with clinicopathological features.Methods:The surgical specimens of colorectal cancer patients hospitalized in Hunan Provincial People's Hospital from January 1, 2020 to September 1, 2020 (without adjuvant treatment measures such as radiotherapy, chemotherapy and immunotherapy) and 45 corresponding adjacent normal tissues were collected. Immunohistochemistry was used to detect the expression of LRP8 in colorectal cancer and paracancer normal tissues. The relationship between LRP8 and clinical characteristics of colorectal cancer patients was determined by univariate logistic regression analysis and Spearman correlation analysis.Results:Immunohistochemical results showed that LRP8 protein was highly expressed in 37 cases (82.22%) and low expressed in 8 cases (17.78%) of 45 colorectal cancer tissues. LRP8 protein was highly expressed in 17 cases (37.78%) and low expressed in 28 cases (62.22%). The expression of LRP8 protein in colorectal cancer tissues and adjacent normal tissues was significantly different ( P<0.05). Chi-square test showed that LRP8 protein expression was correlated with colorectal cancer stage, perineural invasion, vascular invasion, carcinoembryonic antigen (CEA) and low density lipoprotein (LDL) (all P<0.05), but not correlated with gender, age, tumor differentiation, Ki67, CA199, lymph node metastasis, triglyceride, total cholesterol and high density lipoprotein (all P>0.05). Logistic regression analysis showed that tumor node metastasis (TNM) stage, vascular invasion, nerve invasion, serum CEA and LDL levels were the influencing factors of LRP8 overexpression in patients with colorectal cancer (all P<0.05). There was a weak negative correlation between ApoB and tumor stage ( rs=-0.382), lymph node metastasis ( rs=-0.316) and vascular invasion ( rs=-0.311) (all P<0.05). Conclusions:Our results indicate that there is a higher expression of LRP8 in colorectal cancer tissues. The expression of LRP8 correlates with the staging of the colorectal cancer, neurovascular invasion, CEA, and low density lipoprotein. Patients with high expression of LRP8 have worse tumor stage and are more likely to have concurrent neurologic and vascular invasion.
