Impact of the COVID-19 pandemic on the development of burnout syndrome in frontline physicians: prevalence and associated factors

SUMMARY OBJECTIVE: To evaluate the prevalence of burnout syndrome (BS) in physicians working during the COVID-19 pandemic in Paraíba and to investigate the association between BS and the sociodemographic and labor variables of these professionals. METHODS: This was a cross-sectional study including physicians who were active during the pandemic in Paraíba, whether they were on the front line (group 1) or not (group 2). Sociodemographic and labor variables were collected, and the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) questionnaire was applied. RESULTS: A total of 126 physicians were included, including 82 who were on the front line. Among the professionals with results compatible with BS, 85.5% were in group 1, compared with 14.5% in group 2, and this difference was statistically significant. At the 5% level, the variables associated with BS were age (24-33 years), not having children, working on the front line, working in the COVID-19 ICU, being on duty, and having contracted COVID-19. CONCLUSIONS: This case series found a positive association between the development of BS and medical action on the front line of the COVID-19 pandemic in Paraíba.

Subjective Well-Being in India: Socioeconomic and Demographic Determinants and Differentials

Background: In the face of impressive performance in development indicators but poor ranking in the human development indicators, the subjective well-being in India has not been increasing commensurately with the rise in income. The lack of direct long-run relationship between income and happiness in India is a paradox that needs a deeper understanding of the influence of socioeconomic and demographic factors on subjective well-being over space and time. Methodology: The data from five waves of the World Values Survey of India for 24 years over the period 1990-2014 are used. The socioeconomic and demographic determinants of subjective well-being are analysed using chi-square test. The distribution of subjective well-being indicators - happiness, life satisfaction and financial satisfaction - at the group level are examined. Results: The average levels of life satisfaction and happiness have not increased commensurately with income and economic growth over time in India. The happiness level remains constant and life satisfaction and financial satisfaction declined with sharp variations across background characteristics of people and over space and time. Happiness distribution is left-skewed and life satisfaction is related, but not uniformly, with income. Significant differences in well-being exist with respect to education, income, social class, religion, age, marital status and health, but not much with employment and gender. Conclusion: The subjective well-being levels of people of India are influenced by their socioeconomic status with varying degree among different socioeconomic and demographic groups.

Comparative Analysis of Leucocyte Count (Total and Differential) in Patients with Leucocytosis using Sysmex XN550-L Series (5 Part) Automated Analyzer and Conventional Manual Technique in a Tertiary Care Hospital in Rural Haryana

Normal concentration of WBCs in blood varies between 4000 and 11,000 per microliter and are classified intotwo variants namely granulocytes and agranulocytes on the basis of presence and absence of granules.Manual methods of calculation of TLC include- Neubauer chamber and estimating WBC on leishman stainedslides whereas automated methods are based on impedance or light scattering technology. The study comparedthe efficacy of both these methods in statistical terms using Chi Square test. 100 cases of leucocytosisanalyzed over a period of 1 year at MMIMSR, Mullana, Haryana revealed leucocytosis prevalent in 4-6 decadeof life with slight male predominance. The pearson coefficient for TLC came out to be p value =0.215 (notsignificant) but for DLC, calculations revealed p values for polymorphs, lymphocytes, eosinophils andmonocytes to be significant (p value =0.000 each). To conclude, standard manual methods should be advocatedas special practice where there is definite need of morphological and quantitative evaluation of WBCs and tovalidate the automated methods by which the laboratories can optimize patient care and not as a replacement

An Assessment of Eating Disorder among Adolescents and Young Adults

Young males and females are highly concerned about their body image and physical appearance. They refrain themselves from eating that effect the physical and social well-being. This study aims at identifying the presence of eating disorder and to explore as well as confirm four factor solution of eating disorder among adolescents and adults. The study is conducted obtaining data from a sample of 600 adolescents and young adults studying in private and public educational institutions using EDE-Q questionnaire. Chi-square test has revealed the relationship between age and eating concern scores. Pearson correlation test suggested that age is related with global score whereas all the eating disorder scores are inter-related. No gender-wise difference between shape concern and global score is found whereas the global scores and shape concern scores are significantly different with respect to type of institution. Global score and shape concern scores are same for adolescents and young adults. Mean ranks are higher for males compared to females whereas there is significant difference among restraint scores gender-wise however shape concern, weight concern and restraint scores were significantly different in private and public institutions. Mean ranks for young adults are higher for restraint, shape concern, weight concern and eating concern scores compared to adolescents whereas the significant difference was observed between young adults and adolescents for restraint scores. EFA has identified four-factor solution for the EDE-Q subscales whereas CFA has also confirmed it. The four factor solution is weight and shape concern, fear of gaining weight, restraint and eating concern.

Analysing the risky factors of central lymph node metastasis in papillary thyroid microcarcinoma / 国际外科学杂志

Objective To evaluate the relationship between clinicopathological features and central lymph nodes metastasis in patients with papillary thyroid microcarcinoma (PTMC),and aim to provide an appropriate operation in clinic.Methods The clinical data of 536 patients undergoing surgical treatment in Department of Thyroid Surgery,the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2017,who had pathologically confirmed popillary thyroid microcarcinoma (PTMC) were retrospectively analyzed.Thyroidectomy and isthmectomy with central compartment neck dissection were performed in all patients.The patients were divided into two groups according to whether there existed central lymph node metastasis,and compared the differences of gender,age,number of cancer lesions,tumor breakthrough envelope,BRAFV600E gene mutation,and tumor maximum diameter in the central lymph node metastasis,respectively,by t-test x2-test.Univariate logistic regression analysis and multivariate binary logistic regression analysis were conducted to find risky factors.Results There existed difference between two groups by completing the gender,age,the BRAFV600E gene mutation and maximal tumor diameter(P ＜ 0.05).Univariate logistic regression analysis indicated that gender (P =0.046),age (P ＜ 0.01),maximal tumor diameter(P ＜0.01) and the BRAFV600E gene mutation(P =0.016) were significant predictors for central lymph nodes metastasis.And multivariate binary logistic regression analysis revealed that the rate of lymph node metastasis significantly increased in cases of larger tumor diameter(P ＜0.01),BRAFV600E gene mutation(P =0.035) and ageing below 45 years old (P ＜ 0.01).Conclusions The treatment for central lymph node metastasis of PTMC should be different considering elements including BRAF600E gene mutation prophylactic,ageing below 45 years old and larger tumor diameter.Therefore central lymphadenectomy should be performed when the primary lesion was resected.

Técnicas de correção do teste qui-quadrado para amostras não normais / Techniques for correction the chi-square test for non-normal samples / Técnicas de corrección del test chi-cuadrado para muestras no normales

Este artigo tem o objetivo de avaliar técnicas de correções para o teste Qui-Quadrado (χ2) aplicadas a modelos da análise fatorial confirmatória (CFA) em amostras não normais. Em uma abordagem simulada e exploratória, foram mensuradas distribuições distintas em termos de curtose multivariada. Na maioria das situações verificadas, observou-se uma tendência dos testes aferidos de realizar correções diferenciadas dos valores do χ2, CFI e RMSEA em contextos similares. Como conclusão, dentre outros testes avaliados, sugere-se o uso dos seguintes: teste Elíptico com Mínimos Quadrados Reponderados (Teoria Elíptica); teste da Curtose Heterogênea com Mínimos Quadrados Reponderados (Teoria Curtose Heterogênea) e teste Escalado de Satorra-Bentler com Máxima Verossimilhança (para distribuições com excesso de assimetria e/ou curtose univariadas). Porém, devido ao fator de correção, o teste Escalado de Satorra-Bentler pode aceitar modelos moderadamente mal especificados na presença de extrema curtose. (AU)

This paper aims to evaluate techniques for correcting the chi-square test (χ2) as applied to Confirmatory Factor Analysis (CFA) models in non-normal data. In a simulated and exploratory approach, distinct distributions were analyzed in terms of multivariate kurtosis. In most situations, it was observed a tendency of the analyzed tests to produce differing corrections on the χ2 values, as well as for the CFI and RMSEA values. Among other tests evaluated, this study suggested the use of the Elliptical Test with Least Squares (Elliptical Theory), Heterogeneous Kurtosis Test with Reweighted Least Squares (Heterogeneous Kurtosis Theory) and Satorra-Bentler Scaled Test with Maximum Likelihood estimation (for distributions with excessive univariate asymmetry and/or kurtosis). However, due to the correction factor, the Satorra-Bentler Scaled test can accept moderately poorly specified models in the presence of extreme kurtosis. (AU)

En la mayoría de las situaciones verificadas, se observó una tendencia de las pruebas evaluadas de realizar correcciones diferenciadas de los valores del χ2 , CFI y RMSEA en contextos similares. En conclusión, entre otras pruebas evaluadas, se sugiere el uso de las siguientes: Prueba Elíptica con Mínimos Cuadrados Reponderados (Teoría Elíptica); Prueba de la Curtosis Heterogénea con Mínimos Cuadrados Reponderados (Teoría de la Curtosis Heterogénea) y Prueba Escalada de Satorra-Bentler con Máxima Verosimilitud (para distribuciones con exceso de asimetría y/o curtosis univariadas). No obstante, por cuenta del factor de corrección, la Prueba Escalada de Satorra-Bentler puede aceptar modelos moderadamente mal especificados en presencia de extrema curtosis. (AU)

Significance and expression of metdherin in gastric adenocarcinoma and its regulating mechanism of invasion and migration / 国际外科学杂志

Objective This study aimed at observing expression and clinical significance of metadherin in gastric adenocarcinoma and exploring the potentially regulating mechanism of metadherin in invation and migration of gastric cancer.Methods Expressions of metadherin and E-cadherin in primay lesion of gastric cancer were detected by immunohistochemistry and their correlation to clinicopathologic characteristics and prognosis were analyzed by Chi-square tests.Transwell assay and wound healing assay were applied for the ability of invasion and metastasis in gastric cancer cells.Then,the down-regulatied metadherin expression in MKN45 cells by RNA interference (siRNA) was carried out and furthermore,the regulation role of metadherin in epithelial-mesenchymal transition was analyzed also in invasion and migration of gastric cancer cells.Results The positive expression of metadherin was correlated to invading depth (P =0.029),lymph node metastasis (P =0.001),TNM stage (P =0.014) and inhibiting E-cadherin expression (P =0.001).The patients with positive metabherin shared poorer prognosis.Furthermore,the down-regulated metabherin in MKN45 cells would result in the increasing expression of E-cadherin,as well as decreasing expression of N-eadherin,Slug and Snail.At the same time,the abilities of invasion (P =0.027) and migration (P =0.008) of MKN45 cells was decreased.Conclusion metabherin induces EMT in metastasis of gastric adenocarcinoma via activating either Slug or Snail but not twist,which would result in the poorer prognosis.

Objective To explore the related factors of affecting the surgical treatment for aged patients with hip fracture.Methods The data of 139 patients who were over the age of 65 and underwent hip fracture surgery from March 2011 to August 2013 in the People’ s Hospital of Huidong County which affiliated to Guangdong Medical College and the First Affiliated Hospital of Nanchang University were se-lected.According to the Harris hip score at 6 postoperative months,all patients were divided into excellent group and poor group.And the risk factors of hip fracture surgery were explored by univariate analysis and logistic regression analysis.Results Univariate analysis showed that the age, fracture site, fracture type, injury to the operation time, ASA score, ADL score, surgical approach were the single risk factor of af-fecting the recovery of hip function in patients at 6 postoperative months.The age (OR=2.048),fracture type (OR=3.096),fracture type (OR=4.028), injury to the operation time (OR=5.174),preoperative ADL score (OR=3.560) and surgical approach(OR=3.928) were the multiple risk factors.Conclusion The functional recovery of elderly patients with hip fracture after surgery affected by multiple fac-tors,the preoperative prevention should be performed according to the actual situation of patients.

Diferencias de protección frente al riesgo biológico laboral en función del tamaño de la empresa / Differences of occupational biohazard protection risk in relation to company size

Objetivo Obtener información sobre el nivel de exposición y protección de los trabajadores a los agentes biológicos laborales, en el sector sanitario, granjas, industria cárnica, laboratorios, plantas de tratamiento de residuos, industria alimentaria y centros veterinarios valorando sus diferencias en relación al tamaño de la empresa. Método Se realizó un estudio en el que participaron 590 trabajadores pertenecientes a 59 empresas españolas en las que se pasó un cuestionario inicial con 3 preguntas dirigidas a las empresas contestadas por los responsables de prevención y otro cuestionario con 34 preguntas para ser contestado por los trabajadores expuestos. Se realizó una validación mediante análisis del alfa de Cronbach global del segundo cuestionario para valorar la consistencia interna y fiabilidad de los cuestionarios. Resultados La muestra definitiva obtenida fue de 518 trabajadores de 51 empresas en las que existía exposición a agentes biológicos. El cuestionario obtuvo un alfa de Cronbach superior a 0,7. Se encontraron diferencias significativas en la gestión del riesgo biológico laboral en función del tamaño de la empresa (p-valor<0,05). Conclusiones Los resultados obtenidos ofrecieron una adecuada consistencia interna del cuestionario. Por otro lado la exposición laboral a agentes biológicos es un factor que debe tenerse en cuenta puesto que no está desarrollada por completo porque tanto las empresas como los profesionales de la prevención no tienen herramientas disponibles que permitan su fácil realización y por lo tanto la gestión de los riesgos biológicos general no es adecuada.(AU)

Objective To obtain information on the level of exposure and protection of workers to biological agents working in the health sector, farms, meat industry, laboratories, sewage treatment plants, food industry and veterinary centers, valuing their differences in relation to the size of the company. Method A study in which 590 workers belonging to 59 Spanish companies. An initial questionnaire with 3 questions was sent to companies and answered by those responsible for prevention, and another questionnaire with 34 questions to be answered by exposed workers was also sent. Validation was performed by analysis of overall alpha of the second questionnaire to assess the internal consistency and reliability of Cronbach of the questionnaires. Results The final sample included 518 workers in 51 companies in which there was exposure to biological agents. The questionnaire obtained a Cronbach's alpha greater than 0.7. Significant differences in biological risk management work depending on the size of the company (p-value <0.05) were found. Conclusions Our results provide an adequate internal consistency of the questionnaire. Furthermore occupational exposure to biological agents is a factor to be taken into account since it is not fully developed. This is because neither businesses nor prevention professionals have tools available that allow easy implementation, and, therefore, management of overall biological hazards is inadequate.(AU)

Prevalence And Factors Associated With Phobias Among Women

Objective: The present study is carried out to explore the factors associated with phobia, to compare the severity of phobias between cases (mentally ill women) and controls (never mentally ill) and to identify the factors predicting different types of phobias. Methods: A cross sectional study among female cases and controls is conducted. A sample of 150 female respondents including 30 cases and 120 controls is taken to assess the point prevalence of different types of phobias. The Social Phobia Inventory (SPIN) questionnaire was used to identify social phobia on a very severe, severe, moderate, mild and no phobia scale. Pearson chi square and spearman’s rank correlation was applied to assess the associations among different factors and various types of phobias. Results: The most common phobia among the population was Agrizoophobia (93%) followed by Agoraphobia (81%) and Taphophobia (74%). Among cases, age is was associated with Agoraphobia and Acrophobia, marital status of the respondent was associated with Agoraphobia and Acrophobia, marital status of father is associated with social phobia and Aichmophobia, traumatic event was associated with Mysophobia while family income was associated with Acrophobia and Aichmophobia. Age and Agoraphobia, and marital status and Acrophobia show significant results among controls. Multiple discriminant Analysis demonstrated that among cases, age was the best predictor in predicting Agoraphobia and Acrophobia , marital status of father was the best predictor in predicting Nosocomeophobia and traumatic event was the best predictor in predicting Mysophobia. Conclusion: Severe specific phobias are more prevalent among cases while controls suffer from mild specific phobias. Age, marital status of father and traumatic event in life are significant predictors for phobias.
