1.Association of Social Support and Social Activity with Physical Functioning in Older Persons.
Journal of Preventive Medicine and Public Health 2007;40(2):137-144
OBJECTIVES: According to Rowe and Kahn (1998), successful aging is the combination of a low probability of disease, high functioning, and active engagement with life. The purpose of this study was to assess the relationship between active engagement with life and functioning among the community-dwelling elderly. METHODS: Data were collected from Wave 2 of the Suwon Longitudinal Aging Study (SLAS), consisting of a sample of 645 persons aged 65 and older living in the community. A social activity checklist and social support inventory were used as measures of engagement with life, along with the Physical Functioning (PF) scale as a measure of functioning. The effects of social support and social activity on physical functioning, taking into account the covariates, were analyzed by hierarchical linear regression analysis. RESULTS: Maintenance of social activity and social support were significantly associated with higher physical function, after adjusting for sociodemographic and healthrelated covariates. Social support appeared to be more prominent than social activity in predicting physical functioning. CONCLUSIONS: Social support and social activity are potentially modifiable factors associated with physical function in older persons. Studies examining the role social engagement may play in preventing disability are warranted.

Objective:
The purpose of this study was to analyze the current situation concerning professionalism among emergency physicians in South Korea by conducting a survey regarding their perceptions and experiences of unprofessional behavior.
Methods:
In October 2018, the authors evaluated the responses to a questionnaire administered to 548 emergency physicians at 28 university hospitals. The participants described their perceptions and experiences concerning 45 unprofessional behaviors classified into the following five categories: patient care, communication with colleagues, professionalism at work, research, and violent behavior and abusive language. Furthermore, the responses were analyzed by position (resident vs. faculty). Descriptive statistics were generated on the general characteristics of the study participants. To compare differences in responses by position and sex, the chi-square and Fisher exact tests were performed.
Results:
Of the 548 individuals invited to participate in this study, 253 responded (response rate, 46.2%). In 34 out of 45 questionnaires, more than half of participants reported having experienced unprofessional behavior despite their negative perceptions. Eleven perception questions and 38 experience questions for unprofessional behavior showed differences by position.
Conclusion
Most emergency physicians were well aware of what constituted unprofessional behavior; nevertheless, many had engaged in or observed such behavior.

Purpose:
Since the introduction of nab-paclitaxel plus gemcitabine (nab-P+GEM) as first-line (1L) treatment for metastatic pancreatic adenocarcinoma (mPDAC), optimal second-line (2L) chemotherapy after progression is unclear. We assessed clinical outcomes of 2L chemotherapy for disease that progressed on 1L nab-P+GEM.
Materials and Methods:
Among the 203 patients previously treated with 1L nab-P+GEM for mPDAC at Asan Medical Center, between February and December 2016, records of 120 patients receiving 2L chemotherapy after progression on nab-P+GEM were retrospectively reviewed. The response rate and survival were evaluated along with analysis of prognostic factors.
Results:
Fluoropyrimidine-oxaliplatin doublets (FOLFOX or XELOX) were used in 78 patients (65.0%), fluoropyrimidine monotherapy in 37 (30.8%), and liposomal irinotecan plus fluorouracil in two (1.7%). The median progression-free survival (PFS) and overall survival (OS) were 3.29 months and 7.33 months from the start of 2L therapy. Fluoropyrimidine-oxaliplatin regimens and fluoropyrimidine monotherapy did not yield significantly different median PFS (2.89 months vs. 3.81 months, p=0.40) or OS (7.04 months vs. 7.43 months, p=0.86). A high neutrophil-lymphocyte ratio (> 2.2) and a short time to progression with 1L nab-P+GEM (< 6.4 months) were independent prognostic factors of poor OS with 2L therapy.
Conclusion
2L fluoropyrimidine-oxaliplatin doublets and fluoropyrimidine monotherapy after failure of 1L nab-P+GEM had modest efficacy, with no differences in treatment outcomes between them. Further investigation is warranted for the optimal 2L chemo-regimens and sequencing of systemic chemotherapy for patients with mPDAC.
