Objective: Exercise can improve both motor and nonmotor symptoms in people with Parkinson’s disease (PwP), but there is an unmet need for accessible and sustainable exercise options. This study aimed to evaluate the effect, feasibility, and safety of a regularly performed live-streaming tele-exercise intervention for PwP. Methods: A live-streaming exercise intervention for PwP was implemented twice a week for 12 weeks. We measured the motor and nonmotor symptom scores of the included patients before and after the intervention. Changes in clinical scores from baseline to postintervention were analyzed using paired t-tests. Factors associated with improvements in clinical scores and compliance were analyzed using Pearson’s correlation analysis. Results: Fifty-six participants were enrolled in the study. There were significant improvements in Hospital Anxiety and Depression Scale (HADS)-anxiety (p = 0.007), HADS-depression (p < 0.001), Unified Parkinson’s Disease Rating Scale (UPDRS) part III (p < 0.001), UPDRS total (p = 0.015), Hoehn and Yahr stage (p = 0.027), and Parkinson’s Disease Fatigue Scale-16 (p = 0.026) scores after the intervention. Improvements in motor symptoms were associated with improvements in mood symptoms and fatigue. Higher motor impairment at baseline was associated with a greater compliance rate and better postintervention composite motor and nonmotor outcomes (ΔUPDRS total score). Overall, the 12-week tele-exercise program was feasible and safe for PwP. No adverse events were reported. The overall adherence rate was 60.0% in our cohort, and 83.4% of the participants were able to participate in more than half of the exercise routines. Conclusion The live-streaming tele-exercise intervention is a safe, feasible, and effective nonpharmacological treatment option that can alleviate fatigue and improve mood and motor symptoms in PwP.

Background: Recent reports have suggested that pneumonitis is a rare complication following vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).However, its clinical features and outcomes are not well known. The aim of this study was to identify the clinical characteristics and outcomes of patients with vaccine-associated pneumonitis following vaccination against SARS-CoV-2. Methods: In this nationwide multicenter survey study, questionnaires were distributed to pulmonary physicians in referral hospitals. They were asked to report cases of development or exacerbation of interstitial lung disease (ILD) associated with the coronavirus disease 2019 vaccine. Vaccine-associated pneumonitis was defined as new pulmonary infiltrates documented on chest computed tomography within 4 weeks of vaccination and exclusion of other possible etiologies. Results: From the survey, 49 cases of vaccine-associated pneumonitis were identified between February 27 and October 30, 2021. After multidisciplinary discussion, 46 cases were analyzed. The median age was 66 years and 28 (61%) were male. The median interval between vaccination and respiratory symptoms was 5 days. There were 20 (43%), 17 (37%), and nine (19%) patients with newly identified pneumonitis, exacerbation of pre-diagnosed ILD, and undetermined pre-existing ILD, respectively. The administered vaccines were BNT162b2 and ChAdOx1 nCov-19/AZD1222 each in 21 patients followed by mRNA-1273 in three, and Ad26.COV2.S in one patient. Except for five patients with mild disease, 41 (89%) patients were treated with corticosteroid. Significant improvement was observed in 26 (57%) patients including four patients who did not receive treatment. However, ILD aggravated in 9 (20%) patients despite treatment. Mortality was observed in eight (17%) patients. Conclusion These results suggest pneumonitis as a potentially significant safety concern for vaccines against SARS-CoV-2. Clinical awareness and patient education are necessary for early recognition and prompt management. Additional research is warranted to identify the epidemiology and characterize the pathophysiology of vaccine-associated pneumonitis.

Purpose: Diffuse large B-cell lymphoma (DLBCL) is the most common hematologic malignancy worldwide. Although substantial improvement has been achieved by the frontline rituximab-based chemoimmunotherapy, up to 40%-50% of patients will eventually have relapsed or refractory disease, whose prognosis is extremely dismal. Materials and Methods: We have carried out two prospective cohort studies that include over 1,500 DLBCL patients treated with rituximab plus CHOP (#NCT01202448 and #NCT02474550). In the current report, we describe the outcomes of refractory DLBCL patients. Patients were defined to have refractory DLBCL if they met one of the followings, not achieving at least partial response after 4 or more cycles of R-CHOP; not achieving at least partial response after 2 or more cycles of salvage therapy; progressive disease within 12 months after autologous stem cell transplantation. Results: Among 1,581 patients, a total of 260 patients met the criteria for the refractory disease after a median time to progression of 9.1 months. The objective response rate of salvage treatment was 26.4%, and the complete response rate was 9.6%. The median overall survival (OS) was 7.5 months (95% confidence interval, 6.4 to 8.6), and the 2-year survival rate was 22.1%±2.8%. The median OS for each refractory category was not significantly different (p=0.529). Conclusion In line with the previous studies, the outcomes of refractory DLBCL patients were extremely poor, which necessitates novel approaches for this population.

Background/Aims: The prevalence and effects of airway diseases, including asthma, eosinophilic bronchitis (EB), chronic obstructive pulmonary disease (COPD), and asthma-COPD overlap (ACO) have not been thoroughly studied in patients with idiopathic pulmonary fibrosis (IPF). This study aimed to evaluate the prevalence of airway diseases in patients with IPF and to identify the differences in symptoms based on the presence of airway diseases. Methods: This single-institution prospective cohort study was conducted from June 2017 to September 2018, at the Seoul National University Hospital. Spirometry with bronchodilator, methacholine bronchial provocation test, induced sputum with eosinophil stain, and exhaled nitric oxide were performed to confirm the presence of airway disease. The modified Medical Research Council (mMRC) dyspnea scale, COPD assessment test (CAT), St. George’s Respiratory Questionnaire (SGRQ), EuroQol-5 dimension (EQ-5D) index, and cough-specific quality of life questionnaire (CQLQ) data were collected to assess symptom severity. Results: Total 147 patients with IPF were screened, and 70 patients were analyzed. The prevalence of airway diseases in the participants was as follows: 5.0% had COPD, 1.7% had asthma, 3.3% had ACO, and 1.7% had EB. The mMRC, CAT, SGRQ, EQ-5D, and CQLQ scores did not differ regardless of combined airway disease. After 3 months, the SGRQ (p = 0.028) and CQLQ (p = 0.030) scores were significantly higher in patients with airway disease than in those without. Conclusions The prevalence of airway diseases in patients with IPF is low, but when airway diseases are accompanied by IPF, symptom severity and quality of life may worsen rapidly.

Background: Cervical cancer is the fourth common cancer in women worldwide. The Papanicolau test is the primary screening procedure to detect abnormal cervical cells.Colposcopy is the main procedure for discriminating high-grade cervical lesions. The study aimed at clarifying the discrepancy between cervical cytology and colposcopic biopsy histology as well as confounding factors. Methods: Eligible patients visited thirteen tertiary hospitals for colposcopic biopsy following cervical cytology and human papillomavirus (HPV) genotypes between January and December 2018. Baseline characteristics including age, body mass index (BMI), and parity were collected. Results: In our study, 3,798 eligible patients were included. Mean age of patients was 42.7(19–88) years and mean BMI was 22.5 (16.9–34.1) kg/m2 . The referred cervical cytologic findings consisted of 495 normal, 1,390 atypical squamous cells of undetermined significance, 380 atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion, 792 low-grade squamous intraepithelial lesion, 593 high-grade squamous intraepithelial lesion, 79 atypical glandular cells, 46 squamous cell carcinoma, and 23 adenocarcinoma. HPV-positive findings were found in 3,008 (79.2%) patients and were not detected in 914 (24.1%) cases. The risk of unexpected low-grade lesions from histology was higher in patients > 45 years (odds ratio [OR], 2.137; 95% confidence intervals [CIs], 1.475–3.096). In contrast, the risk of unexpected high-grade lesions from colposcopic biopsy was lower in patients ≥ 45 years (OR, 0.530; 95% CI, 0.367–0.747) and HPV 16/18 infection was higher than other HPV (OR, 1.848; 95% CI, 1.385–2.469). Conclusion Age and HPV genotypes were responsible for the discrepancies between cytology and histology. Precautions should be taken for women over the age of 45 in triage for colposcopy in order to avoid unnecessary testing.

Background: The prevalence of impaired fasting glucose (IFG) in Korea is increasing. Few studies have investigated the relationship between handgrip strength (HGS) and type 2 diabetes among Koreans; however, no study has investigated the relationship between IFG and HGS among Koreans. Therefore, we examined the relationship between relative IFG and HGS to evaluate HGS as a marker of prediabetes. Methods: This cross-sectional study analyzed data from participants aged 20 years or older (n=9,190) who did not have diabetes and had had their body mass index, fasting plasma glucose (FPG), and HGS measured in the 2016–2017 Korea National Health and Nutrition Examination Survey. The association between relative HGS and IFG was analyzed using complex sample logistic regression analyses after adjusting for age, education, strengthening exercise, aerobic exercise, smoking, excessive drinking, and chronic diseases. Results: The prevalence of IFG was 31.5 (0.9)% and 19.6 (0.7)% for men and women, respectively. According to the increase in quartile of relative HGS, FPG and HbA1c significantly decreased in both men and women (Ptrend<0.001). In multivariate logistic regression, the odds of IFG significantly decreased with the increase in quartile of relative HGS in both men and women (Ptrend=0.001 for men, Ptrend=0.002 for women). Conclusion This population-based, nationally representative study suggests that higher relative HGS is associated with a decreased risk of IFG for both men and women.

BACKGROUND: Online health information can influence consumers to make informed decisions. There are conflicting messages online about health concerns on the use of e-cigarettes. We aimed to investigate differences in those messages through Naver and Google's English versions, which are the most representative portal sites in Korea and in the world. METHODS: We reviewed the top 100 web pages related to health effects of e-cigarettes on Naver and Google in May 2018. Two medical doctors sorted the web pages into three groups as positive, negative, and mixed messages for e-cigarettes, as well as two groups based on the relative safety of conventional smoking versus e-cigarettes. RESULTS: There were 10 and 27 positive, 65 and 45 negative, and 25 and 28 mixed messages on Naver and Google, respectively. There were 15 messages on Naver and 53 on Google that considered e-cigarettes safer than conventional cigarettes. The most frequent topics were toxicity (71%) and diseases (22%) on Naver. Google provides topics of health concerns for young people, including gateway effect (47%), diseases (35%), and toxicity (25%). Particularly, harm reduction which was not present on Naver, came up on Google as 24%. CONCLUSIONS We found that Naver provides more negative messages on e-cigarettes than does Google, which means that Koreans are exposed more to negative information on e-cigarettes than are foreign people who use Google. In future, more open discussions about harm reduction should be conducted to resolve the imbalance in information regarding health effects of e-cigarettes in Korea.

BACKGROUND: Smoking cessation services for inpatients can be provided effectively through interdisciplinary collaborations. Physicians could play a central role in smoking cessation counseling and treatment for recovery from illness and health promotion of the inpatient. This study aimed to investigate the perspectives of physicians on inpatient smoking cessation services. METHODS: We conducted one personal and two focus group interviews with clinical faculties at a university hospital in Seoul and a university hospital in Chungnam using semi-structured questionnaires. Interviews were recorded, and the transcribed verbatim was analyzed qualitatively. RESULTS: The physicians recognized the need for inpatient smoking cessation services and recognized that smoking cessation was effective when the patient had a smoking-related illness such as respiratory or cardiovascular disease Additionally, the physicians recognized the need for hospital management to support smoking cessation in hospitalized patients and recognized that it was effective to have a dedicated workforce with a smoking cessation coordinator. There was support from four types of physicians in the smoking cessation program: active participant, passive supporter, passive ignorer, and active refuser. CONCLUSIONS The physician is important for the effective implementation of inpatient smoking cessation services. A dedicated team for the smoking cessation of the inpatient, the establishment of evidence-based data on the effectiveness of the inpatient smoking cessation services, and development of customized smoking cessation services will be necessary to strengthen the role of physicians.
