The Impact of Big Five Personality Traits on Older Europeans’ Physical Health

引用

Journal of Biomedical Science and Engineering 2024年第2期17卷 41-56页

作者： Eleni Serafetinidou christina Parpoula Department of Psychology Panteion University of Social and Political Sciences Athens Greece

Investigating the role of Big Five personality traits in relation to various health outcomes has been extensively studied. The impact of “Big Five” on physical health is here explored for older Europeans with a focus on examining age groups differences. The study sample included 378,500 respondents derived from the seventh data wave of Survey of Health, Aging and Retirement in Europe (SHARE). The physical health status of older Europeans was estimated by constructing an index considering the combined effect of well-established health indicators such as the number of chronic diseases, mobility limitations, limitations with basic and instrumental activities of daily living, and self-perceived health. This index was used for an overall physical health assessment, for which the higher the score for an individual, the worst health level. Then, through a dichotomization process applied to the retrieved Principal Component Analysis scores, a two-group discrimination (good or bad health status) of SHARE participants was obtained as regards their physical health condition, allowing for further con-structing logistic regression models to assess the predictive significance of “Big Five” and their protective role for physical health. Results showed that neuroti-cism was the most significant predictor of physical health for all age groups un-der consideration, while extraversion, agreeableness and openness were not found to significantly affect the self-reported physical health levels of midlife adults aged 50 up to 64. Older adults aged 65 up to 79 were more prone to open-ness, whereas the oldest old individuals aged 80 up to 105 were mainly affected by openness and conscientiousness. .

Sclerosing Mucoepidermoid Cancer: A Unique Entity

引用

Open Journal of Endocrine and Metabolic Diseases 2024年第5期14卷 107-114页

作者： Ashima Mittal christina Dimech Farhad Hasan Gayatri Jaiswal Division of Endocrinology Allegheny Health Network Pittsburgh Pennsylvania USA

Sclerosing mucoepidermoid thyroid cancer (SMECE) is a rare entity with less than 100 cases reported in the literature. Previously considered to have an indolent course, however, recent evidence has reported an aggressive nature ranging from local invasion to distant metastasis. We present a 66-year-old Caucasian female with SMECE who initially presented neck compressive symptoms. A thyroid ultrasound (US) revealed a solid hypoechoic mass replacing the left thyroid lobe. Fine needle aspiration cytology (FNAC) of the nodule resulted in suspicion of Papillary Thyroid Cancer, Bethesda category 5. The patient underwent total thyroidectomy and surgical pathology showed SMECE. Post-therapy whole-body scan following treatment with 150 mCi I-131 showed no residual or metastatic disease. SMECE is more common in females, between the third to eighth decade of life. Preoperative diagnosis may not be accurate given variable cytopathologic features. Differential diagnoses include primary squamous cell carcinoma of the thyroid, squamous differentiation of other thyroid malignancies, anaplastic thyroid cancer and nodular sclerosing variety of Hodgkin’s lymphoma. Due to its rarity, treatment of SMECE has ranged from thyroid surgery without or with radioactive iodine therapy, to surgery and external beam radiation and even chemotherapy.
