(1) Background: We aimed to determine whether physicians of different specialties perform differently in the monitoring, cost control, and prevention of acute outcomes in diabetes care. (2) Methods: Using data from the Health and Welfare Data Science Center, participants with newly diagnosed type 2 diabetes (n = 206,819) were classified into three cohorts based on their primary care physician during the first year of diagnosis: family medicine (FM), endocrinologist, and other internal medicine (IM). The three cohorts were matched in a pairwise manner (FM (n = 28,269) vs.

Sarcopenia, characterized by a decline of skeletal muscle mass, has emerged as an important prognostic factor for cancer patients. Trunk computed tomography (CT) is a commonly used modality for assessment of cancer disease extent and treatment outcome. CT images can also be used to analyze the skeletal muscle mass filtered by the appropriate range of Hounsfield scale.

Article Synopsis
  • Low levels of adiponectin (ADPN) are linked to obesity, diabetes, and coronary artery disease, while high levels may be associated with heart issues but little is known about its connection to prolonged QT interval.
  • This study examined the relationship between plasma ADPN levels and prolonged QT interval in patients with stable angina, using 479 participants measured through ECG and plasma tests.
  • Findings showed that patients with an abnormal QTc interval had higher ADPN levels, suggesting that ADPN may contribute to the development of abnormal QTc intervals in stable angina patients.

Introduction: To study the factors affecting the intent to leave of healthcare workers who serve in underserviced areas of Taiwan, the authors tested the mediating role of both professional and organizational commitment in the relationship between perceived investment of employee development and intention to leave among these healthcare workers.

Method: This study was designed as a cross-sectional study using a well-organized questionnaire with major study variables consisting of perceived investment in employees' development (PIED), Meyer's occupational and organizational normative commitment, and intent to leave. In total, 692 healthcare workers from 48 health centers were enrolled for study; 616 people, including 415 (68.

Objective: This study aimed to investigate the characteristics and outcomes of patients with emergency department (ED) revisits within 72 hours and subsequent admission to the intensive care unit (ICU).

Materials And Methods: The medical records of all adult patients revisiting the ED of a single tertiary referral medical center with ICU admissions between January 2012 and September 2014 were reviewed in terms of patient characteristics, clinical manifestations, diagnoses, triage according to the Taiwan Triage and Acuity Scale, causes of revisits, and mortality.

Results: The majority of the 51 patients reviewed were male (64.

Background: Governments are urged to determine methods to control the use of medical resources and curb the rise of healthcare costs. The question is, do health behaviors have an impact on the use of medical resources? This study aims to identify and understand the difference in the number of outpatient visits and health examinations based on various health behaviors and to determine whether patients seek medical care for illness from the same physicians.

Methods: This study used the dataset derived from the Department of Budget, Accounting and Statistics of Kaohsiung, Taiwan in 2005.

Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare and acquired hematopoietic stem cell disease, with florid clinical presentations. Although this disease has been characterized in the western countries, its clinical and laboratory features in Taiwan have not yet been reported.

Results: As a part of an international prospective, non-interventional, observational registration trial of PNH, we have analyzed 63 patients recruited between 2009 and 2015 in Taiwan, with comparison to the 3857 patients in the rest of the world (ROW).

Many studies have demonstrated that non-adherence to oral anticancer drugs (OACDs) has challenged treatment efficacy. Otherwise, few validated tools exist to measure patients' adherence to medication regimen in clinical practice. To synthesize previous studies on adherence by cancer patients taking OACDs, especially in targeted therapy, a systematic search of several electronic databases was conducted.

Thromboembolism is a complication of hematopoietic stem cell transplant. However, a literature search showed no previous reports of cerebral infarction during the thrombocytopenic stage after hematopoietic stem cell transplant. A 35-year-old woman with acute lymphoblastic leukemia (precursor B-cell type) was treated with hematopoietic stem cell transplant after induction and consolidation chemotherapy.

This study aimed to evaluate the survival rate of women with breast cancer (BC) comparing persistence versus interruption and adherence versus non-adherence to adjuvant hormonal therapy (HT) in Asian population. Newly-diagnosed BC women from 2003 to 2010 were retrospectively identified from the Taiwan National Health Insurance Research Database. HT prescriptions were extracted to define treatment interruption and medication possession ratio.
