ABSTRACT

Background/Aims@#We aimed to compare the effectiveness and safety of Janus kinase inhibitors (JAKi) vs. biologic disease- modifying antirheumatic drugs (bDMARD) in Korean patients with rheumatoid arthritis (RA) who had an inadequate response to conventional synthetic DMARDs. @*Methods@#A quasi-experimental, multi-center, prospective, non-randomized study was conducted to compare response rates between JAKi and bDMARDs in patients with RA naïve to targeted therapy. An interim analysis was performed to estimate the proportion of patients achieving low disease activity (LDA) based on disease activity score (DAS)–28– erythroid sedimentation rate (ESR) (DAS28-ESR) at 24 weeks after treatment initiation and to evaluate the development of adverse events (AEs). @*Results@#Among 506 patients enrolled from 17 institutions between April 2020 and August 2022, 346 (196 JAKi group and 150 bDMARD group) were included in the analysis. After 24 weeks of treatment, 49.0% of JAKi users and 48.7% of bDMARD users achieved LDA (p = 0.954). DAS28-ESR remission rates were also comparable between JAKi and bDMARD users (30.1% and 31.3%, respectively; p = 0.806). The frequency of AEs reported in the JAKi group was numerically higher than that in the bDMARDs group, but the frequencies of serious and severe AEs were comparable between the groups. @*Conclusions@#Our interim findings reveal JAKi have comparable effectiveness and safety to bDMARDs at 24 weeks after treatment initiation.

ABSTRACT

Purpose@#This study aimed to evaluate the validity and reliability of the Korean version of the Quality of Life in LifeThreatening Illness - Family Carer Version 3 (QOLLTI-F v3) among Korean family caregivers of patients with terminal cancers. @*Methods@#A total of 198 family caregivers of terminal cancer patients were investigated using the Korean version of QOLLTI-F v3. Its psychometric properties were examined in terms of factor structure, convergent validity, discriminant validity, criterion validity and internal consistency. @*Results@#The convergent validity of the Korean version of QOLLTI-F v3 showed that the standardized regression weights for each item were above .50 except for two out of 16 items, the average variance extracted was above .50 for four out of five factors, and the critical ratio ranged from .50 to .85. The discriminant validity of the items across all factors was confirmed. The value for Cronbach’s α of 16 items was .84. @*Conclusion@#The Korean version of the QOLLTI-F v3 is a reliable instrument with acceptable convergent and high discriminant validity for measuring the quality of life of families of people with life-threatening illnesses, including families of people with terminal cancers.

ABSTRACT

Background@#Alcohol consumption has been considered as a modifiable risk factor for dementia development and alcohol-related brain damage may further impair cognitive abilities in dementia patients. This study aimed to find out the differences in cognitive function according to current alcohol drinking in patients with self-perceived memory decline, including subjective cognitive decline (SCD), mild cognitive impairment (MCI) and early Alzheimer-type dementia (ATD). @*Methods@#From May 2018 to December 2019, retrospective chart review was performed in patients who visited CHA Bundang Medical Center for cognitive decline. A two-way analysis of variance with interaction test were used to analyze the impact of alcohol consumption on cognitive function between groups. @*Results@#A total of 147 patients was classified into three groups of SCD (n=30), MCI (n=53), and ATD (n=64), and each group was divided into two subgroups of alcohol users and alcohol non-users, according to the current status of alcohol consumption. Between SCD, MCI and ATD groups, scores of clock drawing test and Go/No-go test were significantly lower in current alcohol users of ATD groups compared to the SCD and MCI groups (p<0.05). @*Conclusions@#These results suggest that current alcohol consumption has detrimental effects especially on the frontal/executive function in early ATD patients. Considering the association between frontal/executive function and ADL, our finding suggests that cessation of alcohol intake may be a therapeutic strategy to prevent ADL deterioration in patients with ATD.

ABSTRACT

Purpose@#This study aimed to describe nurses’ perceived needs and barriers to pediatric palliative care (PPC). @*Methods@#Mixed methods with an embedded design were applied. An online survey was conducted for nurses who participated in the End-of-Life Nursing Education Consortium- Pediatric Palliative Care (ELNEC-PPC) train-the-trainer program, of whom 63 responded. Quantitative data were collected with a survey questionnaire developed through the Delphi method. The 47 items for needs and 15 items for barriers to PPC were analyzed with descriptive statistics. Qualitative data were collected through openended questions and analyzed with topic modeling techniques. @*Results@#The mean scores of most subdomains of the PPC needs were 3.5 or higher out of 4, and those of PPC barriers ranged from 3.22 to 3.56, indicating the items in the questionnaire developed in this study properly reflect each factor. The needs for PPC were divided into 4 categories: “children and adolescents,” “families,” “PPC management system,” and “community-based PPC.” Meanwhile, PPC barriers were divided into 3 categories: “healthcare delivery system,” “healthcare provider,” and “client.” The keywords derived from the topic modeling were perception, palliative, children, and education for necessities and lack, perception, medical care, professional care providers, service, and system for barriers to PPC. @*Conclusion@#In this study, by using mixed-methods, items of nurses’ perceived needs and barriers to PPC were identified, categorized, and weighted, and their meanings were explored. For the stable establishment of PPC, the priority should be given to improving perceptions of PPC, establishing an appropriate system, and training professional care providers.

ABSTRACT

Hospice palliative care refers to holistic care provided by an interdisciplinary team aimed at improving the quality of life of patients suffering from life-threatening diseases and their families. Among interdisciplinary team members, hospice advanced practice nurses (APNs) trained as master’s-level advanced nursing professionals are leaders who play an important role in providing patient-centered care and improving the quality of services. The Medical Service Act revised in 2018 requires the scope of practice of APNs in each field to be specified in the Ordinance of the Ministry of Health and Welfare. Accordingly, discussions on the role and scope of practice of hospice APNs are actively underway. In this review, the curriculum of hospice APNs, their work responsibilities and roles, and their current status are reviewed, and the future direction of the hospice APN system is also discussed.

ABSTRACT

Background/Aims@#Systemic sclerosis (SSc) is associated with a wide range of gastrointestinal (GI) changes. The University of California–Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract (UCLA SCTC GIT 2.0) instrument is a self-administered GI assessment instrument for patients with SSc. We developed a Korean version of the UCLA SCTC GIT 2.0 instrument and evaluated its reliability and internal consistency. @*Methods@#The participants were 37 Korean patients with SSc. Translation and cross-cultural adaptation of the UCLA SCTC GIT 2.0 were performed according to international standardized guidelines. We evaluated reproducibility by calculating the intraclass correlation coefficients and assessed the internal consistency of the Korean version of the UCLA SCTC GIT 2.0. We assessed its construct validity by evaluating its correlations with the Short Form Health Survey version 2 and EQ-5D scores by means of Spearman correlation analyses. @*Results@#Patients with SSc were mostly women (89.19%) with a mean age of 52.2 years, median disease duration of 24 months, and median modified Rodnan total skin score of 4. The median total GIT score on the UCLA SCTC GIT 2.0 was 0.3. The UCLA SCTC GIT 2.0 Korean version showed excellent internal consistency (Cronbach’s α of total GIT score = 0.863). Most domains of the ULCA SCTC GIT 2.0 were correlated with those of the EuroQol (EQ)-5D score. @*Conclusions@#The Korean version of the UCLA SCTC GIT 2.0 has acceptable internal consistency, reliability, and validity. Therefore, it can be used to assess GIT involvement in Korean patients with SSc.

ABSTRACT

Patients with systemic rheumatic diseases (SRD) are vulnerable for coronavirus disease (COVID-19). The Korean College of Rheumatology recognized the urgent need to develop recommendations for rheumatologists and other physicians to manage patients with SRD during the COVID-19 pandemic. The working group was organized and was responsible for selecting key health questions, searching and reviewing the available literature, and formulating statements. The appropriateness of the statements was evaluated by voting panels using the modified Delphi method. Four general principles and thirteen individual recommendations were finalized through expert consensus based on the available evidence. The recommendations included preventive measures against COVID-19, medicinal treatment for stable or active SRD patients without COVID-19, medicinal treatment for SRD patients with COVID-19, and patient evaluation and monitoring. Medicinal treatments were categorized according to the status with respect to both COVID-19 and SRD. These recommendations should serve as a reference for individualized treatment for patients with SRD. As new evidence is emerging, an immediate update will be required.

ABSTRACT

Objective@#This study aimed to identify the clinical characteristics for differential diagnosis of Parkinson’s disease dementia (PDD) and dementia with Lewy bodies (DLB) by analyzing the differences in cognitive function and caregiver burden between the patient groups. @*Methods@#We conducted a retrospective cross-sectional study with idiopathic Parkinson’s disease patients and DLB patients. Differences in cognitive function were measured using the standardized neuropsychological test battery (Seoul Neuropsychological Screening Battery-II). Differences in the caregiver burden were measured by the Neuropsychiatric Inventory-Questionnaire (NPIQ) for behavioral psychological symptoms of dementia (BPSD) and Korean-Instrumental Activities of Daily living (K-IADL) for daily living activities. For statistical analysis, chi-square test and multivariate analysis of variance and binary logistic regression and correlation analysis were conducted using SPSS 22. @*Results@#Nine Parkinson’s disease-Normal cognition (PD-NC), 25 Parkinson’s disease-mild cognitive impairment (PD-MCI), 20 PDD and 11 DLB patients were included. Compared with PDD and DLB, attentional deficit correlated more strongly with DLB, but language dysfunction showed more correlation with PDD. Caregiver burden correlated more strongly with DLB than PDD. Delusion and aberrant motor behaviors of NPI-Q and taking medicine of K-IADL were strongly related with the caregiver burden of both PDD and DLB. @*Conclusion@#This study identified that neuropsychological profile and caregiver burden in comparison of BPSD and ADL can contribute to the differential diagnosis of PDD and DLB.

ABSTRACT

Purpose@#This study aimed to grasp the correlation between communication ability, empathy, and interpersonal relations among nursing students, and to explore the mediating effect of empathy on the relation between communication and interpersonal relation in nursing students. @*Methods@#Participants were 209 college students in the Department of Nursing at two universities. The data collection period was from October 1, 2019 to November 1, 2019. The questionnaire consisted of measuring tools for general characteristics, communication ability, interpersonal relation and empathy. SPSS/23.0 program was used. The analysis used descriptive statistics, Pearson's correlation coefficient, independent t-test, one-way ANOVA, multiple regression analysis, and Sobel's tests. @*Results@#The communication ability was nursing major satisfaction (t=8.25, p<.001), and last year's average grade (t=7.29, p=.001). Interpersonal relationships showed significant differences in gender (t=2.51, p=.013) and nursing major satisfaction (t=10.99, p<.001). Communication ability and empathy (r=.37, p<.001), communication ability and interpersonal relation (r=.77, p<.001), empathy and interpersonal relation (r=.43, p<.001) showed a significant static correlation. In communication ability and interpersonal relation, empathy had a partial mediating effect (Z=2.97, p<.001), and explanatory power was 62%. @*Conclusion@#To improve the communication ability and interpersonal relation of nursing students, it is necessary to develop a personalized and empathy-enhanced education program for each grade.

ABSTRACT

Background/Aims@#Our study aims to characterize esophageal motor function; evaluate the relationships among esophagogastroduodenoscopy (EGD), high-resolution manometry (HRM), and 24-hour esophageal multichannel intraluminal impedance monitoring combined with pHmetry (MII-pH); and elucidate the determinants of esophageal symptom perception in South Koreans with systemic sclerosis (SSc). @*Methods@#We reviewed prospectively collected HRM (n = 46), EGD (n = 41), and MII-pH (n = 37) data from 46 consecutive patients with SSc (42 females; mean age 50.1 years) who underwent esophageal tests between June 2013 and September 2018. @*Results@#The most common HRM diagnosis was normal (39.1%), followed by ineffective esophageal motility (23.9%) and absent contractility (21.7%). Erosive esophagitis was observed in 12.2% of total SSc patients, with a higher frequency in patients with absent contractility than those with normal motility (44.5% vs 0.0%, P = 0.01). Pathologic acid exposure was observed in 6 patients (20.0%) and positive symptom association in 18 patients (60.0%) in MII-pH tests of symptomatic patients. The proportion of SSc patients with esophageal symptoms not explained by reflux or mucosal or motor esophageal abnormalities was 33.0%. @*Conclusions@#Esophageal involvement among South Koreans with SSc was characterized by heterogeneous motility patterns, with a higher prevalence of normal motility and lower prevalence of erosive esophagitis. Reflux hypersensitivity or functional heartburn might be partly attributed to the perception of esophageal symptoms in SSc patients who have neither gastroesophageal reflux disease nor esophageal dysmotility.

ABSTRACT

Huntington’s disease (HD) is a dominantly inherited neurodegenerative disorder caused by abnormally expanded CAG repeats in the huntingtin gene. The huntingtin gene mutation leads to the progressive degeneration of striatal GABAergic medium spiny neurons (MSN) and reduces the level of brain-derived neurotrophic factor (BDNF) in HD patient’s brain. BDNF is an essential neurotrophic factor for the cortico-striatal synaptic activity and the survival of GABAergic neurons. In this study, we transplanted BDNF-overexpressing human neural stem cells (HB1.F3.BDNF) into the contra-lateral side of unilateral quinolinic acid (QA)-lesioned striatum of HD rat model. The results of in vivo transplantation were monitored using various behavioral tests, 4.7 T animal magnetic resonance imaging (MRI) and immunohistochemical staining. We observed that the QA-lesioned rats receiving HB1.F3.BDNF cells exhibited significant behavioral improvements in the stepping, rotarod and apomorphine-induced rotation tests. Interestingly, contralaterally transplanted cells were migrated to the QA-lesioned striatum and the size of lateral ventricle was reduced. Histological analyses further revealed that the transplanted cells, which had migrated to the QA lesion site, were differentiated into the cells of GABAergic, MSN-type neurons expressing DARPP-32, and neural networks were established between the transplanted cells and the host brain, as revealed by retrograde tracing. Finally, there was a significant reduction of inflammatory response in HB1.F3.BDNF-transplanted HD animal model, compared with vehicle-transplanted group. Taken together, these results suggest that HB1.F3.BDNF can be an effective therapeutic strategy to treat HD patients in the future.

ABSTRACT

@#Objectives: We aimed to investigate the demographics and medical management factors associated with dependence on hypnotics among outpatients with neurological disorders and insomnia. Methods: We reviewed electronic medical records of patients who received an initial hypnotic prescription between January 2014 and January 2016 and had later visited a neurological outpatient clinic before January 2018. We assessed patient demographics, the effectiveness of hypnotics, prescription periods, and hypnotic intake methods during the follow-up period. Results: Of 242 patients diagnosed with insomnia, we enrolled 114 patients (more women than men, at 61.4 versus 38.6%) who visited outpatient clinics regularly during the follow-up period. The mean age at onset was 65.8 ± 14.4 years. The most frequent neurological disorder was cerebrovascular disease, followed by neurodegenerative disease. During the 2-year period, 35.9% of participants remained hypnotics-free. Patients on zolpidem showed significantly greater insomnia improvement with hypnotic discontinuation than those on benzodiazepines and combination therapy (p=0.004). However, the type of hypnotics and demographic factors were not found to be independent risk factors. Multivariable analysis showed that longer periods between regular visits and a lower ratio of receiving number of pills to the time interval (days) between regular visits were independent risk factors for dependence on hypnotics. Conclusions: We found that low-dose and/or intermittent intake of hypnotics as well as frequent doctor visits could prevent dependence on hypnotics. It is important to establish the best practical guidelines for medical hypnotics management in outpatient primary care settings, including neurological clinics.

ABSTRACT

Raynaud's phenomenon (RP) is a reversible vasospasm that is aggravated by cold or emotional stress. Before confirming RP, it is essential to consider other possible causes including compressive neuropathy, sensori-neuropathy, thyroid disease, hematologic conditions and offending drugs. RP is typically characterized by the three-step color change that turns pallor (white), cyanosis (blue), and then erythema (red) of reperfusion. Once RP is diagnosed, it is important to determine whether it is primary or secondary RP. To distinguish primary from the secondary RP, the specialized tests performing in clinical practice are antinuclear antibody (ANA) and nailfold capillary microscopy (NFC). The combination of ANA and NFC is most helpful for discriminating secondary RP due to autoimmune rheumatic disease. Thereby, normal findings of NFC in primary RP distinguished from secondary RP should be understood. Patients with primary RP usually improves with symptomatic treatment focused on lifestyle modification and patient education, but those with secondary RP should be treated together with associated disease or causes.

ABSTRACT

PURPOSE: This study examined the effects of a mobile app-based program to reduce the dietary sugar intake according to the stages of the behavioral change in dietary sugar reduction in female college students. METHODS: The program used in this study can monitor the dietary sugar intake after recording the dietary intake and provide education message for the reduction of dietary sugar intake. In an eight-week pre-post intervention study, 68 female college students were instructed to record all the food they consumed daily and received weekly education information. At pre-post intervention, the subjects were asked to answer the questionnaire about sugar-related nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. For statistical analysis, ANOVA and a paired t-test were used for comparative analysis according Precontemplation (PC), Contemplation ·Preparation (C ·P), and A ·M (Action ·Maintenance) stage. RESULTS: Significant differences were observed in the frequency of snacking, experience of nutrition education, and preference for sweetness according to the stages of behavior change in dietary sugar reduction. After finishing an intervention, the sugar-related nutrition knowledge score was increased significantly in the stages of Precontemplation (PC) and Contemplation ·Preparation (C ·P). The score of the sugar intake behavior increased significantly in all stages. The intake frequency of chocolate, muffins or cakes, and drinking yogurt decreased significantly in the PC stage and the intake frequency of biscuits, carbonated beverages, and fruit juice decreased significantly in the C ·P stage. Subjects in the PC and C ·P stages had an undesirable propensity in nutrition knowledge, sugar-intake behavior, and sugar-intake frequency compared to the A ·M stage, but this intervention improved significantly their nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. CONCLUSION: This program can be an effective educational tool in the stages of PC and C ·P, and is expected to further increase the usability and sustainability of mobile application if supplemented appropriately to a health platform program.

ABSTRACT

BACKGROUND: Tetrabromobisphenol A (TBBPA), one of the most widely used brominated flame-retardants, is a representative persistent organic pollutants group. Studies on TBBPA toxicity have been conducted using various target cells; however, few studies have investigated TBBPA toxicity in bone cells. Therefore, this study investigated the in vitro effects of TBBPA on osteoclasts, a cell type involved in bone metabolism. METHODS: RAW264.7 cells were cultured in medium containing 50 ng/mL receptor activator of nuclear factor kappa B ligand (RANKL) and varying concentrations of TBBPA. To evaluate the effects of TBBPA on the differentiation and function of osteoclasts, osteoclast-specific gene expression, tartrate-resistant acid phosphatase (TRAP) activity, bone resorbing activity, mitochondrial membrane potential (MMP) and mitochondrial superoxide were measured. RESULTS: The presence of 20 μM TBBPA significantly increased TRAP activity in RANKL-stimulated RAW264.7 cells, the bone resorbing activity of osteoclasts, and the gene expression of Akt2, nuclear factor of activated T-cells cytoplasmic 1, and chloride channel voltage-sensitive 7. However, TBBPA treatment caused no change in the expression of carbonic anhydrase II, cathepsin K, osteopetrosis-associated transmembrane protein 1, Src, extracellular signal-related kinase, GAB2, c-Fos, or matrix metalloproteinase 9. Furthermore, 20 μM TBBPA caused a significant decrease in MMP and a significant increase in mitochondrial superoxide production. CONCLUSION: This study suggests that TBBPA promotes osteoclast differentiation and activity. The mechanism of TBBPA-stimulated osteoclastogenesis might include increased expression of several genes involved in osteoclast differentiation and reactive oxygen species production.

ABSTRACT

BACKGROUND/OBJECTIVES: Several previous studies have investigated whether regular walnut consumption positively changes heart-health-related parameters. The aim of this study was to investigate the effects of daily walnut intake on metabolic syndrome (MetS) status and other metabolic parameters among subjects with MetS. SUBJECTS/METHODS: This study was a two-arm, randomized, controlled crossover study with 16 weeks of each intervention (45 g of walnuts or iso-caloric white bread) with a 6 week washout period between interventions. Korean adults with MetS (n = 119) were randomly assigned to one of two sequences; 84 subjects completed the trial. At each clinic visit (at 0, 16, 22, and 38 weeks), MetS components, metabolic parameters including lipid profile, hemoglobin A1c (HbA1c), adiponectin, leptin, and apolipoprotein B, as well as anthropometric and bioimpedance data were obtained. RESULTS: Daily walnut consumption for 16 weeks improved MetS status, resulting in 28.6%-52.8% reversion rates for individual MetS components and 51.2% of participants with MetS at baseline reverted to a normal status after the walnut intervention. Significant improvements after walnut intake, compared to control intervention, in high-density lipoprotein cholesterol (HDL-C) (P = 0.028), fasting glucose (P = 0.013), HbA1c (P = 0.021), and adiponectin (P = 0.019) were observed after adjustment for gender, age, body mass index, and sequence using a linear mixed model. CONCLUSION: A dietary supplement of 45 g of walnuts for 16 weeks favorably changed MetS status by increasing the concentration of HDL-C and decreasing fasting glucose level. Furthermore, consuming walnuts on a daily basis changed HbA1c and circulating adiponectin levels among the subjects with MetS. This trial is registered at ClinicalTrials.gov as NCT03267901.
