RESUMEN
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.
RESUMEN
A 65-year-old male patient with an end-stage renal disease was diagnosed with coronavirus disease 2019 (COVID-19) by reverse transcription polymerase chain reaction. The patient complained of cough, sputum, and respiratory distress that worsened three days ago. The patient required mechanical ventilation and extracorporeal mentrane oxygenation. On day 9, convalescent plasma collected from a 34-year old man who recovered from COVID-19 45 days ago was administered. The patient showed immediate clinical improvement. However, on day 14, the patient’s clinical course worsened again. On day 19 and day 24, vancomycin-resistant Enterococcus faecium bacteremia and methicillin-resistant Staphylococcus aureus pneumonia were found. After long-term supportive care, he slowly recovered. He was discharged on day 91 without any oxygen requirement. This case report suggests that convalescent plasma therapy might just provide a short-term relief and that persistent effort for critical care is necessary to save patients from severe COVID-19.
RESUMEN
Bipolar disorder is a mental illness that causes extreme mood swings and has a chronic course. However, the mechanism by which mood episodes with completely opposite characteristics appear repeatedly, or a mixture of symptoms appears, in patients with bipolar disorder remains unknown. Therefore, mood stabilizers are indicated only for single mood episodes, such as manic episodes and depressive episodes, and no true mood-stabilizing drugs effective for treating both manic and depressive episodes currently exist. Therefore, in this review, therapeutic targets that facilitate the development of mood stabilizers were examined by reviewing the current understanding of the neuromolecular etiology of bipolar disorder.
RESUMEN
Background@#The goal of this study is to investigate the relationship between depression and glycated hemoglobin in the general Korean population. @*Methods@#Adults aged 19 to 80 years were surveyed as part of the 2019 Korea National Health and Nutrition Examination Survey. A total of 4,831 people were chosen to complete the health questionnaire, provide their body mass index, and get a HbA1c blood test. The general characteristics of groups with high and low glycated hemoglobin were identified. To find out the correlation between depression diagnosis and the general population with high glycated hemoglobin, a chi-square test was carried out. A t-test was also used to compare the means of glycated hemoglobin between the groups diagnosed with and not diagnosed with depression. In analyzing the relationship between depression and glycated hemoglobin, analysis of covariance was performed by adjusting the effects for demographic factors. @*Results@#Sex, age, income level, education level, drinking, smoking, exercise, and body mass index are all factors that influence glycated hemoglobin. The mean glycated hemoglobin was high in the group diagnosed with depression. The relationship between depression and glycated hemoglobin could not be confirmed using logistic regression after controlling for confounding variables. @*Conclusion@#There was no significant correlation between depression and glycated hemoglobin in the general population of Korea based on the results of this study.
RESUMEN
Mutations in the Leucine-rich repeat kinase 2 (LRRK2 ) gene are the most prevalent cause of familial Parkinson’s disease (PD). The increase in LRRK2 kinase activity observed in the pathogenic G2019S mutation is important for PD development. Several studies have reported that increased LRRK2 kinase activity and treatment with LRRK2 kinase inhibitors decreased and increased ciliogenesis, respectively, in mouse embryonic fibroblasts (MEFs) and retinal pigment epithelium (RPE) cells. In contrast, treatment of SH-SY5Y dopaminergic neuronal cells with PD-causing chemicals increased ciliogenesis. Because these reports were somewhat contradictory, we tested the effect of LRRK2 kinase activity on ciliogenesis in neurons. In SH-SY5Y cells, LRRK2 inhibitor treatment slightly increased ciliogenesis, but serum starvation showed no increase. In rat primary neurons, LRRK2 inhibitor treatment repeatedly showed no significant change. Little difference was observed between primary cortical neurons prepared from wild-type (WT) and G2019S +/- mice. However, a significant increase in ciliogenesis was observed in G2019S +/- compared to WT human fibroblasts, and this pattern was maintained in neural stem cells (NSCs) differentiated from the induced pluripotent stem cells (iPSCs) prepared from the same WT/G2019S fibroblast pair. NSCs differentiated from G2019S and its gene-corrected WT counterpart iPSCs were also used to test ciliogenesis in an isogenic background. The results showed no significant difference between WT and G2019S regardless of kinase inhibitor treatment and B27-deprivation-mimicking serum starvation. These results suggest that LRRK2 kinase activity may be not a direct regulator of ciliogenesis and ciliogenesis varies depending upon the cell type or genetic background.
RESUMEN
Background@#This study explores the correlation among obesity, suicide plans, and suicide attempts in adults over 19 years of age in South Korea. @*Methods@#The study used data from adults who had participated in the 2018 Korea National Health and Nutrition Examination Survey. Obesity was defined as having a body mass index of ≥25 kg/m 2 . To identify differences between the characteristics of those who had reported suicide plans and attempts, a complex sample chi-square test was conducted. To analyze the effect of obesity on suicide plans and attempts, a logistic regression analysis was performed. @*Results@#There was no significant difference in the rate of suicide plans in one year between obese and non-obese groups; however, the rate of actual suicide attempts was significantly high in the obese group (p<0.050). After correcting for variables that were significantly different between the groups, obesity was found to have no significant effect on suicide plans but was linked to a significant increase in suicide attempts (odds ratio=3.355, p=0.008). @*Conclusion@#Obesity was found to have no effect on the suicide planning rate; however, the probability of a suicide attempt was high in obese adults.
RESUMEN
Objectives@#The aim of this study was to examine the clinical presentation, treatment delivery, and cisplatin eligibility of Korean patients with urothelial carcinoma (UC) in a real-world setting. @*Methods@#We performed a retrospective cohort study of patients initially diagnosed with UC from March 2013 to June 2018. Creatinine clearance >60 mL/min and Eastern Cooperative Oncology Group performance status (0–1) were adopted as cisplatin eligibility criteria. @*Results@#This study included 557 eligible patients. Median age was 71.0 years (range, 33–94 years), and males were dominant (80%). Primary tumor sites were: upper genitourinary tract, 18%; bladder, 81%; and urethra, 0.4%. Initial disease status was non-muscle invasive bladder cancer (313, 56%), diffuse infiltrating non-muscle invasive bladder cancer (19, 3%), cTanyN0 upper tract UC (75, 13%), cT2-4N0 bladder UC (82, 15%), TanyN1-3 UC (36, 7%), or initially metastatic UC (32, 6%). At the time of analysis (June 2019), following treatments were delivered to 134 patients with localized UC: radical operation with or without perioperative treatment (89, 67%), definitive chemoradiation (7, 5%), and palliative surgery or supportive care only (36, 28%). In total, 89 patients had metastatic UC, including those with recurrent disease (n=57), and 34 (38%) of the 89 were eligible for cisplatin. @*Conclusion@#Clinical presentations in East Asian UC patients were consistent with those of previous studies in other countries, except for a relatively high incidence of upper genitourinary tract. Our results can serve as a benchmark for further advances and future research for treatments of UC in East Asian patients.

RESUMEN
Background@#This study aims to investigate the relationship between metabolic syndrome and depression in Korean adults using data from the 2016 and 2018 Korean National Health and Nutrition Examination Surveys (KNHANES). @*Methods@#The total number of participants in the 7th period 1st year (2016) and 3rd year (2018) surveys of KNHANES was 16142. This study was conducted with 10,722 subjects who met the diagnostic criteria for metabolic syndrome and responded to the Patient Health Questionnaire-9 (PHQ-9). Analysis of covariance was used to adjust the differences due to demographic factors, laboratory findings, and underlying diseases to understand the relationship between metabolic syndrome and PHQ-9 scores, if any. @*Results@#The prevalence of metabolic syndrome was determined to be 25.6% in this study. The PHQ-9 scores with and without metabolic syndrome were 2.56 and 2.48, respectively, and there was no significant difference when the confounding variable was corrected (p=0.406). According to the analysis of each PHQ-9 item and metabolic syndrome, the results were not significant. @*Conclusion@#In this cross-sectional study conducted in Korean adults, no significant correlation was found between metabolic syndrome and depression.
RESUMEN
Purpose@#The Advanced Prostate Cancer Consensus Conference (APCCC) 2015 was based on topics withcontroversy in the field of advanced prostate cancer. To understand the Korean urologists perspective regardingthe issues, we have conducted a questionnaire named Prostate Cancer Summit (PCAS) 2016, with 9 importantsubtopics. @*Materials and Methods@#Total 9 subtopics have been decided and questions were developed regarding eachsubtopic. The questions were based on that of APCCC 2015 and translated into Korean for better understanding.Total 51 panelists have voted online on 85 different questions. @*Results@#The survey concluded that testosterone should be measured as a diagnostic criterion for castrationresistance prostate cancer (CRPC) and that consensus was reached on issues such as the use of androgenreceptor pathway inhibitors in the treatment of predocetaxel and postdocetaxel in CRPC patients. In addition,76% of the participants agreed that imaging tests were needed before new treatment in CRPC patients, anda majority of participants agreed that periodic imaging tests are necessary regardless of symptoms during treatmentfor CRPC. However, some issues, such as the use of prostate-specific antigen-based triggers for remediationin CRPC patients, the endocrine manipulation in nonmetastatic CRPC patients, and the onset of treatment inasymptomatic metastatic CRPC patients, were not agreed. @*Conclusions@#The results from PCAS 2016 has addressed some of the issues with controversy. Although thevoting results are subjective, it will help guide treatment decisions in topics with less evidence.
RESUMEN
Background@#Calprotectin is the major cytosolic protein in neutrophil granulocytes.Although asthma is known to cause eosinophilic inflammation, some patients with asthma have non-eosinophilic inflammation, which is characterized by local neutrophilic inflammation. The aim of this study was to assess calprotectin expression levels in a mouse model of asthma, and to observe the relationship of serum calprotectin level and clinical variables in patients with asthma. @*Methods@#Mice were sensitized and challenged with 10 μg and 20 μg of Aspergillus fumigatus, respectively; mice treated with saline were used as a control. The levels of calprotectin were determined using enzyme-linked immunosorbent assay, immunoblotting, and immunohistochemical analysis. The serum levels of calprotectin were also assessed in patients with asthma. The relationship between calprotectin and clinicopathological characteristics was determined. @*Results@#Calprotectin, S100A8, and S100A9 expression was elevated in the mouse lungs, Calprotectin levels were higher in the serum of patients with asthma (n = 33) compared with those of healthy individuals (n = 28). Calprotectin levels correlated with forced expiratory volume in one second/forced vital capacity (r = −0.215, P = 0.043), smoke amount (r = 0.413, P = 0.017), body mass index (r = −0.445,P= 0.000), and blood neutrophil percentage (r = 0.300, P = 0.004) in patients with asthma. @*Conclusion@#Our data suggest that calprotectin could potentially be used as a biomarker for asthma.
RESUMEN
Idiopathic interstitial pneumonia (IIP) is a histologically identifiable pulmonary disease without a known cause that usually infiltrates the lung interstitium. IIP is largely classified into idiopathic pulmonary fibrosis, idiopathic non-specific interstitial pneumonia, respiratory bronchiolitis-interstitial lung disease (ILD), cryptogenic organizing pneumonia, desquamative interstitial pneumonia, and acute interstitial pneumonia. Each of these diseases has a different prognosis and requires specific treatment, and a multidisciplinary approach that combines chest high-resolution computed tomography (HRCT), histological findings, and clinical findings is necessary for their diagnosis. Diagnosis of IIP is made based on clinical presentation, chest HRCT findings, results of pulmonary function tests, and histological findings. For histological diagnosis, video-assisted thoracoscopic biopsy and transbronchial lung biopsy are used. In order to identify ILD associated with connective tissue disease, autoimmune antibody tests may also be necessary. Many biomarkers associated with disease prognosis have been recently discovered, and future research on their clinical significance is necessary. The diagnosis of ILD is difficult because patterns of ILD are both complicated and variable. Therefore, as with other diseases, accurate history taking and meticulous physical examination are crucial.
RESUMEN
PURPOSE: To evaluate changes in the expression of androgen receptor (AR) and its variants (ARVs) in human prostate cancer (PCa) tissues according to disease status, and its prognostic significance following radical prostatectomy (RP). MATERIALS AND METHODS: A total of 282 PCa cases were evaluated, which included 252 localized PCa, 8 metastatic castration resistant prostate cancer (CRPC), and 22 benign prostatic hyperplasia (BPH) cases. Samples were collected from patients who underwent RP or transurethral resection and were stored in ethically approved tissue banks. Quantitative real-time polymerase chain reaction, Western blotting, and immunohistochemistry were performed for AR and ARVs. Each tissue was confirmed as cancerous (greater than 80%) using hematoxylin and eosin staining. AR and ARVs expression was compared according to disease status. The biochemical recurrence free survival (BCRFS) rates in men with localized PCa was analyzed according to AR and ARV7 expression using the Kaplan-Meier curve. RESULTS: Only 58 of the 252 localized PCa were included in the analysis because of insufficient cancer tissue. AR and ARV7 mRNA expression was higher in the CRPC tissue than in the localized PCa tissue (p=0.025, p=0.002, respectively). In localized PCa tissue, high AR mRNA and protein level was associated with a low BCRFS rate (log-ranked, p=0.019, p < 0.001, respectively). CONCLUSIONS: Overall AR and ARV7 mRNA expression levels were increased in CRPC tissues compared to localized PCa and BPH tissues. High AR protein and mRNA expression in the tumor tissue may be considered a predictive factor of BCRFS following RP.

BACKGROUND: Combination of metformin to reduce the fasting plasma glucose level and an α-glucosidase inhibitor to decrease the postprandial glucose level is expected to generate a complementary effect. We compared the efficacy and safety of a fixed-dose combination of voglibose plus metformin (vogmet) with metformin monotherapy in drug-naïve newly-diagnosed type 2 diabetes mellitus. METHODS: A total of 187 eligible patients aged 20 to 70 years, with a glycosylated hemoglobin (HbA1c) level of 7.0% to 11.0%, were randomized into either vogmet or metformin treatments for 24 weeks. A change in the HbA1c level from baseline was measured at week 24. RESULTS: The reduction in the levels of HbA1c was −1.62%±0.07% in the vogmet group and −1.31%±0.07% in the metformin group (P=0.003), and significantly more vogmet-treated patients achieved the target HbA1c levels of <6.5% (P=0.002) or <7% (P=0.039). Glycemic variability was also significantly improved with vogmet treatment, estimated by M-values (P=0.004). Gastrointestinal adverse events and hypoglycemia (%) were numerically lower in the vogmet-treated group. Moreover, a significant weight loss was observed with vogmet treatment compared with metformin (−1.63 kg vs. −0.86 kg, P=0.039). CONCLUSION: Vogmet is a safe antihyperglycemic agent that controls blood glucose level effectively, yields weight loss, and is superior to metformin in terms of various key glycemic parameters without increasing the risk of hypoglycemia.

PURPOSE: Claudin-4 has been reported to function as a paracellular sodium barrier and is one of the 3 major claudins expressed in lung alveolar epithelial cells. However, the possible role of claudin-4 in bronchial asthma has not yet been fully studied. In this study, we aimed to elucidate the role of claudin-4 in the pathogenesis of bronchial asthma. METHODS: We determined claudin-4 levels in blood from asthmatic patients. Moreover, using mice sensitized and challenged with OVA, as well as sensitized and challenged with saline, we investigated whether claudin-4 is involved in the pathogenesis of bronchial asthma. Der p1 induced the inflammatory cytokines in NHBE cells. RESULTS: We found that claudin-4 in blood from asthmatic patients was increased compared with that from healthy control subjects. Plasma claudin-4 levels were significantly higher in exacerbated patients than in control patients with bronchial asthma. The plasma claudin-4 level was correlated with eosinophils, total IgE, FEV1% pred, and FEV1/FVC. Moreover, lung tissues from the OVA-OVA mice showed significant increases in transcripts and proteins of claudin-4 as well as in TJ breaks and the densities of claudin-4 staining. When claudin-4 was knocked down by transfecting its siRNA, inflammatory cytokine expressions, which were induced by Der p1 treatment, were significantly increased. CONCLUSIONS: These findings thus raise the possibility that regulation of lung epithelial barrier proteins may constitute a therapeutic approach for asthma.

OBJECTIVE: In the current study, we investigated whether there are relations among depressive symptoms, cognitive performance and serum BDNF levels in the patients with chronic kidney disease (CKD). METHODS: Sixty patients with CKD and 65 healthy controls participated. Depressive symptoms were evaluated with Beck depression inventory (BDI) and Hamilton Depression Rating Scale (HDRS). Mini-Mental State Examination included in the Korean version of the Consortium to Establish a Registry for Alzheimer’s disease (MMSE-KC) assessment packet was used for the evaluation of overall cognitive function. To assess memory function, the Korean version of the Hopkins Verbal Learning Test (K-HVLT) was used. BDNF levels were measured using an enzyme-linked immunosorbent assay (ELISA) kit. RESULTS: The CKD patients showed more depressive symptoms when compared with controls. The depressive symptoms and cognitive function were not associated with serum BDNF levels in the CKD patients. CONCLUSION: In the current study, CKD patients had more depressive symptoms when compared controls. However, the serum BDNF levels of CKD patients were not associated with depressive symptoms and cognitive functions. These findings suggested that the serum BDNF levels may not be reflect the cognitive function and depressive mood state in the CKD patients.

BACKGROUND@#Elderly patients with multiple myeloma (MM) are vulnerable to adverse events (AEs). This study evaluated adherence to chemotherapy and treatment outcomes in elderly patients treated with a frontline bortezomib (BTZ), melphalan, and prednisone (VMP) regimen and regimens without BTZ.@*METHODS@#One-hundred and forty elderly patients who were diagnosed with MM from March 2007 to March 2015 were included in this retrospective study. To evaluate regimen adherence, patients who were treated with more than 4 cycles were assigned to the good adherence group.@*RESULTS@#Among the 140 patients, 71 were treated with a frontline VMP and 69 with non-BTZ regimens. The median age was 71 years (range, 65-90 years). The VMP group showed a higher complete response rate than the non-BTZ group: 26.8% vs. 7.2%. More patients in the VMP group achieved ≥ very good partial response (VGPR) and ≥ PR. In the VMP group, 27 patients (38.0%) received less than 4 cycles. The VMP good adherence group showed a higher 3-year overall survival (OS) rate (70.9%) than the poor adherence group (60.2%, p=0.059). In the multivariate analysis, treatment with ≥ 4 cycles of VMP was a favorable factor for OS.@*CONCLUSION@#A good adherence to a frontline VMP regimen resulted in favorable long-term survival. Adequate management of AEs will be needed to achieve favorable outcomes in elderly patients with MM.
