[Work ethic, organizational commitment and burnout]. / Etyka pracy i przywiazanie organizacyjne a wypalenie zawodowe.

BACKGROUND: This work aims to present the results of a research study on the relations between work ethic, organizational commitment and job burnout. The authors investigated a sample of employees representing different industries and companies, e.g., lawyers, IT specialists, medical doctors, clerks, teachers and railwaymen (N = 335). MATERIAL AND METHODS: The research study was based on the Job Demands-Resources model. The work ethic measured by the Polish adaptation of the Multidimensional Work Ethic Profile consisted of 8 factors: the value of hard work, work as a central value of life, unwillingness to waste time, aversion to free time, delayed gratification, self-reliance, morality, and work as a moral duty. The organizational commitment measured by the Organizational Commitment Scale consisted of 3 components: affective commitment, normative commitment and continuance commitment. To measure job burnout, the Polish adaptation of the Link Burnout Questionnaire was used, which is composed of 4 dimensions of burnout: psycho-physical exhaustion, relationship deterioration, the sense of professional failure, and disillusion. RESULTS: The study shows that work ethic dimensions and organizational commitment are negatively correlated with job burnout. Significant predictors which can reduce job burnout include work as a moral duty, the value of hard work, work as a central value of life, aversion to free time and morality as dimensions of work ethic and affective commitment. CONCLUSIONS: Some dimensions of work ethic and organizational commitment constitute job resources and can decrease job burnout. Work ethic, and affective and normative commitment reduce the sense of disillusion. Med Pr. 2019;70(3):305-16.

[Place of thyroglobulin antibodies assay in laboratory diagnostic of autoimmune thyroid diseases]. / Miejsce oznaczen poziomu przeciwcial anty-tyreoglobulinowych w diagnostyce autoimunologicznych chorób tarczycy.

Tyroglobulin and thyroid peroxidase antibodies have been estimated in patients with thyroid autoimmune diseases. In a group of 109 patients with Hashimoto's thyroidities 85.53% and 78.89% were positive for Tyroglobulin antibodies and anti-TPO antibodies respectively. The anti-Tg antibodies has not been detected in 14.67% and anti-TPO in 21.1% patients. Both antibodies have not been detected in 1.83% of patients. In a group of 79 patients with Graves' disease 62.02 and 91.13% were positive for anti-Tg and anti-TPO antibodies respectively. The anti-Tg antibodies has not been detected in 37.97% and anti-TPO in 8.66% patients. Both antibodies have not been detected in one patients with exophtalmos (1.26%). Our results indicate that anti-tyroglobulin antibodies should be estimated only in patients suspected for thyroid autoimmune disease and negative for thyroid peroxidase antibodies.

Ganglioside reactive antibodies of IgG and IgM class in sera of patients with differentiated thyroid cancer.

We searched for the presence of ganglioside reactive antibodies in sera of patients with differentiated thyroid cancer (DTC). Sera were screened by ELISA with plates coated with GM3(NeuAc), GM3(NeuGc), GM2, GM1, FucGM1, GD3, GD1a or GD1b gangliosides. Ganglioside reactive antibodies were detected more frequently in sera of patients with DTC than in sera of healthy persons, in keeping with the possibility of autoimmunization during carcinogenesis. Antibodies of IgM and IgG classes reactive with FucGM1 occurred most often. However, the infrequent occurrence of ganglioside reactive antibodies, their low titer and lack of correlation between their presence and clinical condition of the patients indicate that determination of these antibodies has no diagnostic value in DTC.
