Purpose: The purpose of this study was to examine the suffering experienced by the primary caregiver of people with mental disabilities in community dwellings to explain the fundamental structure thereof. Methods: The Giorgi’s phenomenological research methodology was used. Three male subjects and five female subjects participated in this study. The data were collected September-December, 2019 through in-depth individual interviews, and analysis based on the Giorgi’s method. Results: Four clusters of themes were identified. They are: “Mental disability came as a burden of pain”, “Painful time from caring due to being mentally recoiled and being hurtful”, “My life is broken by illness”, and “Hope discovered in the midst of pain”. Conclusion The findings provide deeper understanding and insight into the suffering experienced by primary caregivers for people with mental disabilities in community dwellings. A comprehensive program encompassing psychological and social aspects must be developed to facilitate resolving the problem of the suffering experienced by the primary caregiver for people with mental disabilities.

OBJECTIVES: Anhedonia, defined as an inability to experience pleasure, has been considered to be a core feature of schizophrenia and depression. The purpose of the present study was to compare the specific characteristics of anhedonia in patients with the two illnesses by examining hedonic capacity during phased hedonic experience. METHODS: Hedonic rating tasks, using the film clips of physical and social hedonic stimuli and neutral stimuli, were performed by 29 patients with schizophrenia, 20 patients with depression, and 29 normal controls. Each task consisted of 'preview phase' with insufficient emotional information, and a subsequent 'theme phase' with sufficient emotional information. RESULTS: In normal controls, the mean hedonic score was increased in the theme phase compared with the preview phase, suggesting an appropriate augmentation of the hedonic response. In patients with schizophrenia, hedonic scores in the preview phase were comparable with those in normal controls, but showed deficient augmentation in the theme phase. In patients with depressive disorder, the range of increments in scores between the preview and theme phases was normal, but the scores themselves were lower in both phases than in the other two groups. CONCLUSION: The results indicate that patients with schizophrenia show a deficient augmentation of the hedonic response, whereas patients with depressive disorder have a pervasive lack of hedonic capacity.

We aimed to investigate the significance of microalbuminuria and its relationship with subclinical atherosclerosis in nonhypertensive and nondiabetic patients, by using coronary artery computed tomography (CT). A total of 1,318 nonhypertensive and nondiabetic subjects who had taken coronary artery CT and measured spot urine albumin to creatinine ratio (UACR) were evaluated. The atherosclerotic changes of coronary arteries were greater in subjects with microalbuminuria, reflected by coronary artery calcium score (CACS) and significant coronary artery stenosis (CACS > or = 100 in 15.3% vs 7.6% and stenosis > or = 50% in 11.5% vs 4.9% of patients with vs without microalbuminuria, P = 0.008 and P = 0.011, respectively). Among various parameters that are known as a risk factor or possible biomarkers of coronary artery disease, presence of microalbuminuria, age and Framingham risk score were significantly related to coronary artery stenosis. Among them the presence of microalbuminuria showed stronger correlation than others to the coronary artery stenosis detected by CT, even after adjusting confounding factors (OR 3.397, 95% confidence interval 1.138 to 10.140, P = 0.028). The presence of microalbuminuria by UACR was significantly associated with presence of coronary artery stenosis > or = 50% in asymptomatic, nonhypertensive and nondiabetic general population. Our study suggests that the presence of microalbuminuria may imply subclinical coronary artery disease, even in asymptomatic population.

Rheumatoid arthritis (RA) is an autoimmune disease involving the synovial membrane of peripheral joints. T cells specific for self antigens may play a critical role. Identification of T cell receptors (TCR) of such specific T cell clones is very important for treatment, prevention and identification of relevant autoantigens. To identify specific T cells, TCR V beta family repertoire and the clonal expansion of T cells were analyzed in this study. The percentage of V beta 5+ or V beta 8+ cells in the synovial fluid mononuclear cells (SFMCs) was similar to that in the peripheral blood mononuclear cells (PBMCs). However, the percentage of DR+ T cells in the SFMCs was higher (p< 0.01). Analyzing the clonality of T cells in 8 V beta families (V beta 1, V beta 5, V beta 8, V beta 14, V beta 16, V beta 17, V beta 18, V beta 20), clonal expansions in CD8+ T cells from the SFMCs were found more frequently than in the PBMCs. The patterns of clonal expansions were discrepant between the SFMCs and the PBMCs even in the same patient, which suggests several inflamed tissue specific T cell clonal expansions in the SFMCs. These T cell clones might be activated by autoantigens which are not identified yet and responsible for the RA pathogenesis.

We aimed to investigate the role of bone scintigraphy (BS) in the diagnosis of rheumatoid arthritis (RA) as a supplement to the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) criteria. A total of 156 patients who underwent BS with screening laboratory to confirm RA were enrolled. We divided them into two groups according to the presence of arthritis upon the first physical examination, and evaluated the diagnostic validity of BS as an independent (BS only) or assistant diagnostic tool using the 2010 criteria (BS-assisted). Seventy-five patients had active arthritis (Group I), while the remaining 81 patients did not (Group II). Among them, 56 patients in group I and 5 patients in group II were finally classified as RA. In the group I patients who were eligible for application of the 2010 criteria, the sensitivity of the BS only and BS-assisted diagnosis was not superior to that of the 2010 criteria. However, BS-assisted diagnosis showed high positive prediction values in group I patients with 2010 criteria score < 6 and group II patients. Therefore, BS is still helpful to detect RA even after the introduction of the 2010 criteria, especially among patients who do not satisfy the 2010 criteria as well as those who are ineligible for the 2010 criteria due to dubitable arthritis at clinical presentation.

In spite of frequent usage of primary human foreskin keratinocytes (HFKs) in the study of skin biology, senescence-induced blockage of in vitro proliferation has been a big hurdle for their effective utilization. In order to overcome this passage limitation, we first isolated ten HFK lines from circumcision patients and successfully immortalized four of them via a retroviral transduction of high-risk human papillomavirus (HPV) E6 and E7 oncogenes. We confirmed expression of a keratinocyte marker protein, keratin 14 and two viral oncoproteins in these immortalized HFKs. We also observed their robust responsiveness to various exogenous stimuli, which was evidenced by increased mRNA expression of epithelial differentiation markers and pro-inflammatory genes in response to three reactive chemicals. In addition, their applicability to cytotoxicity assessment turned out to be comparable to that of HaCaT cells. Finally, we confirmed their differentiation capacity by construction of well-stratified three dimensional skin cultures. These newly established immortalized HFKs will be valuable tools not only for generation of in vitro skin disease models but also for prediction of potential toxicities of various cosmetic chemicals.

Purpose: The purpose of this study was to understand the employment experiences of female Mongolian migrant workers in Korea and identify their meanings. Methods: Data were collected through individual in-depth interviews with eight such women using the phenomenological Colaizzi qualitative research approach. Results: Six categories were drawn from the research: “Facing a dilemma when hitting the wall,” “Foreigners’ lives disrespected,” “Physically filled with wounds,” “Lonely, laborious, and sad,“ “Growing stronger and knowledgeable,” and “Happiness found in the workplace.” Conclusion The results of this study revealed the substantial meaning of the employment experience of female Mongolian migrant workers in Korea. The results of the study could provide basic data for offering such women various kinds of programs to support them psychologically and in their adjustment to their jobs. These programs would enhance their ability to adapt to both working and in Korea.

PURPOSE: The purpose of this study was to describe arterial spin labeling MR image findings of status epilepticus. MATERIALS AND METHODS: A retrospective chart review within our institute revealed six patients who had been clinically diagnosed as status epilepticus and had also undergone MR imaging that included ASL in addition to routine sequences. RESULTS: Six patients with status epilepticus were studied by conventional MR and arterial spin labeling imaging. All patients showed increased regional CBF correlating with EEG pathology. Notably, in two patients, conventional MRI and DWI showed no abnormal findings whereas pCASL demonstrated regional increased CBF in both patients. CONCLUSION: Arterial spin labeling might offer additional diagnostic capabilities in the evaluation of patients with status epilepticus.

The aim of the present study was to identify the influence of vertebral fracture (VF) on the functional disability in patients with rheumatoid arthritis (RA). This study consecutively enrolled 100 female patients aged 50 yr or older with RA. All participants underwent lateral imaging of the thoracolumbar spine by simple radiography to identify any VFs. They also completed questionnaires via interview regarding demographics, medical history, and disease outcomes including functional disability. We used univariate analysis to evaluate associations between functional disability and VF, and made multivariate logistic regression models to test independent effect of the presence of VF, the number of VFs, and the severity of VF on functional disability. Among the 100 RA patients, 47 had at least one VF, but 34 of them were asymptomatic that they had experienced a fracture. The multiple VFs > or = 3 (OR, 8.95; 95% CI, 1.77-44.15, P = 0.01) and moderate or severe VF (OR, 3.38; 95% CI, 1.26-9.04, P = 0.02) were related to disability in univariate analysis. The multiple VFs > or = 3 (OR, 6.13; 95% CI, 1.02-36.94, P = 0.048) was associated with functional disability of RA patients after adjusting various confounders and it was mainly in walking and arising. The VF might be an important factor which affects functional disability in RA patients.

PURPOSE: This study investigated the prevalence of smoking, drinking, and physical inactivity and the associated factors of these behaviors in gastric cancer survivors. MATERIALS AND METHODS: The baseline data from the nationwide cohort study was used. Four hundred thirty-seven gastric cancer survivors who survived ≥ 2 years from diagnosis and reported completion of treatment were matched with 4,370 controls according to age, sex, education, and household income. RESULTS: The prevalence rates of current smoking and drinking among gastric cancer survivors were 8.7% and 38.3%, which were significantly lower than those among matched controls (p ≤ 0.001), but the prevalence rates of physical inactivity were not significantly different (55.8% vs. 59.9%, p=0.248). In gastric cancer survivors, ≥ 5 years since cancer diagnosis and current drinking contributed to more current smoking; otherwise, age increment and femalewere associatedwith lower current smoking. Thosewith household income ≥ $2,000 and current smokers were more likely to drink and female showed less drinking. Female, currently employed state, and self-rated health status were associated with more physical inactivity. CONCLUSION: Although gastric cancer survivors showed better health behaviors than controls, suggesting that the diagnosis of cancer may motivate individuals towards healthy behaviors, their current prevalence rates of smoking and drinking were still high, and more than 50% of them were physically inactive. Tailored interventions to improve their health behaviors considering associated factors for the gastric cancer survivors are necessary.
