ABSTRACT

Purpose@#This phase II, open-label, multicenter study aimed to investigate the efficacy and safety of a rituximab intensification for the 1st cycle with every 21-day of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP-21) among patients with previously untreated advanced-stage or bulky diffuse large B-cell lymphoma (DLBCL). @*Materials and Methods@#Ninety-two patients with stage III/IV or bulky DLBCL from 21 institutions were administered 8 cycles of R-CHOP-21 with an additional one dose of rituximab intensification on day 0 of the 1st cycle (RR-CHOP). The primary endpoint was a complete response (CR) rate after 3 cycles of chemotherapy. @*Results@#Among the 92 DLBCL patients assessed herein, the response rate after 3 cycles of chemotherapy was 88.0% (38.0% CR+50.0% partial response [PR]). After the completion of 8 cycles of chemotherapy, the overall response rate was observed for 68.4% (58.7% CR+9.8% PR). The 3-year progression-free survival rate was 64.0%, and the 3-year overall survival rate was 70.4%. Febrile neutropenia was one of the most frequent grade 3 adverse events (40.0%) and 5 treatment-related deaths occurred. Compared with the clinical outcomes of patients who received R-CHOP chemotherapy as a historical control, the interim CR rate was higher in male patients with RR-CHOP (20.5% vs. 48.8%, p=0.016). @*Conclusion@#Rituximab intensification on days 0 to the 1st cycle of the standard 8 cycles R-CHOP-21 for advanced DLBCL yielded favorable response rates after the 3 cycles of chemotherapy and acceptable toxicities, especially for male patients.

ABSTRACT

Purpose@#This study aimed to compare long-term clinical outcomes according to the use of emergency medical services (EMS) in patients with ST-segment elevation myocardial infarction (STEMI) who arrived at the hospital within 12 hr of symptom onset. @*Materials and Methods@#A total of 13104 patients with acute myocardial infarction were enrolled in the Korea Acute Myocardial Infarction Registry–National Institutes of Health from October 2011 to December 2015. Of them, 2416 patients with STEMI who arrived at the hospital within 12 hr were divided into two groups: 987 patients in the EMS group and 1429 in the non-EMS group. Propensity score matching (PSM) was performed to reduce bias from confounding variables. After PSM, 796 patients in the EMS group and 796 patients in the non-EMS group were analyzed. The clinical outcomes during 3 years of clinical follow-up were compared between the two groups according to the use of EMS. @*Results@#The symptom-to-door time was significantly shorter in the EMS group than in the non-EMS group. The EMS group had more patients with high Killip class compared to the non-EMS group. The rates of all-cause death and major adverse cardiac events (MACE) were not significantly different between the two groups. After PSM, the rate of all-cause death and MACE were still not significantly different between the EMS and non-EMS groups. The predictors of mortality were high Killip class, renal dysfunction, old age, long door-to-balloon time, long symptom-to-door time, and heart failure. @*Conclusion@#EMS utilization was more frequent in high-risk patients. The use of EMS shortened the symptom-to-door time, but did not improve the prognosis in this cohort.

ABSTRACT

Purpose@#Event-free survival at 24 months (EFS24) is known to be a surrogate marker for overall survival (OS) for patients with peripheral T-cell lymphoma (PTCL). We examined the role of EFS24 in PTCL compared to diffuse large B-cell lymphoma (DLBCL), and then assessed the clinical predictive factors of achieving EFS24. @*Materials and Methods@#Patients with newly diagnosed PTCL treated with anthracycline-based chemotherapy were included. Subsequent OS was defined as the time elapsed from 24 months after diagnosis until death from any cause in those who achieved EFS24. @*Results@#Overall, 153 patients were evaluated, and 51 patients (33.3%) achieved EFS24. Patients who achieved EFS24 showed superior OS compared to patients who did not (p < 0.001). EFS24 could stratify the subsequent OS although it did not reach to that of the general population. After matching the PTCL group to the DLBCL group based on the international prognostic index, the subsequent OS in patients who achieved EFS24 was similar between the two groups (p=0.094). Advanced stage was a significant factor to predict the failing EFS24 by multivariable analysis (p < 0.001). @*Conclusion@#Patients with PTCL who achieve EFS24 could have a favorable subsequent OS. Since advanced disease stage is a predictor of EFS24 failure, future efforts should focus on developing novel therapeutic strategies for PTCL patients presenting with advanced disease.

ABSTRACT

POEMS syndrome is an acronym for polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes. It is a rare paraneoplastic disorder related to plasma cell neoplasm. However, its pathophysiology has not yet been clearly elucidated. The production of pro-inflammatory cytokines is thought to play an important role in the pathogenesis of POEMS syndrome. Vascular endothelial growth factor level reflects disease activity, which is helpful for the diagnosis and evaluation of treatment response. Conventional agents such as corticosteroids and melphalan are effective and safe combination regimens. Autologous hematopoietic stem cell transplantation is another option for high-risk transplant-eligible patients. Radiotherapy is effective in patients with localized lesions. The anti-myeloma agents lenalidomide, thalidomide, and bortezomib have shown good treatment outcomes for POEMS syndrome; however, large-scale studies with long-term follow-up are required. Early identification and active treatment can improve the outcomes of POEMS syndrome patients.

ABSTRACT

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of defective apoptosis, a disruption of the regulatory pathway that terminates immune and inflammatory responses.Fever, cytopenia, splenomegaly, and/or hemophagocytosis are typical findings of this syndrome. HLH can be induced by genetic disorders (familial) or secondary causes.Familial HLH is rare, while secondary causes in adults include infection, autoimmunity, and malignancy. HLH in adults tends to be confused with or misdiagnosed as sepsis, mainly due to similar clinical manifestations and laboratory findings, which make it difficult to diagnose HLH rapidly and adopt immunosuppressive agents and/or chemotherapy adequately. Treatment of pediatric HLH using HLH-2004 or multi-agent chemotherapy can be applied in adult patients, although the dose and type of drug need to be adjusted.It is highly recommended that allogenic hematopoietic stem cell transplantation should be used in patients who become reactivated or are refractory to the initial treatment as soon as possible to improve survival. Future clinical trials are warranted to determine more suitable treatments for adult patients with HLH.

ABSTRACT

Dental trauma is very common in children and relatively young people, with the line of treatment depending on the time elapsed, age of the child, and tooth maturity. If the fractured segment is available and there is close approximation of the segment to the remaining tooth, reattachment of the fractured segment is a feasible option. This treatment offers several advantages, including the reestablishment of function, aesthetics, shape, shine and surface texture, in addition to the original contour and alignment of the teeth. The following cases present two different complex crown fracture cases that were treated using tooth fragment reattachment with fiber-reinforced composite post.

ABSTRACT

Background/Aims@#Febrile neutropenia (FN) interferes with the proper chemotherapy dose density or intensity in non-Hodgkin’s lymphoma (NHL) patients. Chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) ± rituximab has an intermediate FN risk. Prophylactic granulocyte colony-stimulating factor (G-CSF) support is recommended for patients with other host-related risk factors. @*Methods@#We evaluated the risk factors for FN-related admission in NHL patients who have received primary G-CSF (lenograstim) prophylaxis. @*Results@#Data from 148 patients were analyzed. The incidence of neutropenic fever was 96 events (12.2%), and the median period was 3.85 days (range, 0 to 5.9); the median duration of neutropenia was 4.21 days (range, 3.3 to 5.07). Eighty-three FN-related admissions were reported. Advanced age (> 60 years), female sex, a low albumin level, and prednisone use were associated with FN-related admission in multivariable analysis (p = 0.010, p < 0.001, and p = 0.010, respectively). A comparison between diffuse large B-cell lymphoma patients treated with R-CHOP and pegylated G-CSF and those treated with R-CHOP and lenograstim did not reveal significant differences in the FN-related admission rate between the two groups, although the lenograstim-treated group had a higher incidence of severe neutropenia. @*Conclusions@#Elderly patients, female patients, and patients with low albumin levels need to be actively followed-up for FN even when primary prophylaxis with G-CSF has been used.

ABSTRACT

Background/Aims@#Although the use of surveillance 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is discouraged in patients with diffuse large B-cell lymphoma, its usefulness in different subtypes has not been thoroughly investigated. @*Methods@#We retrospectively evaluated 157 patients who showed positive results on surveillance FDG-PET/CT every 6 months following complete response for up to 5 years. All of the patients also underwent biopsies. @*Results@#Seventy-eight (49.6%) of 157 patients had true positive results; the remaining 79 (50.3%), including eight (5.1%) with secondary malignancies, were confirmed to yield false positive results. Among the 78 patients with true positive results, the disease in seven (8.9%) had transformed to a different subtype. The positive predictive value (PPV) of FDG-PET/CT for aggressive B-cell non-Hodgkin’s lymphoma (NHL) was lower than that for indolent B-cell or aggressive T-cell NHL (p = 0.003 and p = 0.018, respectively), especially in patients with a low/low-intermediate international prognostic index (IPI) upon a positive PET/CT finding. On the other hand, indolent B-cell and aggressive T-cell NHL patients showed PPVs of > 60%, including those with low/low-intermediate secondary IPIs. @*Conclusions@#The role of FDG-PET/CT surveillance is limited, and differs according to the lymphoma subtype. FDG-PET/CT may be useful in detecting early relapse in patients with aggressive T-cell NHL, including those with low/low-intermediate risk secondary IPI; as already known, FDG-PET/CT has no role in aggressive B-cell NHL. Repeat biopsy should be performed to discriminate relapse or transformation from false positive findings in patients with positive surveillance FDG-PET/CT results.

ABSTRACT

Background/Aims@#This study compared long-term clinical outcomes between male and female acute myocardial infarction (AMI) patients with and without diabetes mellitus (DM). @*Methods@#From November 2011 to December 2015, 13,104 patients with AMI were enrolled in the Korea Acute Myocardial Infarction Registry National Institutes of Health (KAMIR-NIH) (4,458 diabetic patients and 8,646 non-diabetic patients). Propensity score matching (PSM) was used to reduce bias due to confounding variables. Following PSM, 2,046 diabetic patients, 1,023 males (69.8 ± 9.4 years) and 1,023 females (69.9 ± 9.4 years); and 3,412 non-diabetic patients, 1,706 males (70.0 ± 10.4 years) and 1,706 females (70.4 ± 10.8 years) were analyzed. Clinical outcomes were compared between male and female patients with and without diabetes over a 3-year clinical follow-up. @*Results@#In diabetic patients, mortality (21.1% vs. 21.5%, p = 0.813) and major adverse cardiac events (MACE) (30.6% vs. 31.4%, p = 0.698) were not significantly different between males and females. However, mortality (15.8% vs. 12.0%, p = 0.002) and MACE (20.8% vs. 15.6%, p < 0.001) were significantly higher in male non-diabetic patients than in female non-diabetic patients. The predictors of mortality for both males and females in the diabetic and non-diabetic groups were old age, heart failure, renal dysfunction, anemia, and no percutaneous coronary intervention. @*Conclusions@#The long-term clinical outcomes in AMI patients with DM did not significantly differ by sex. However, the mortality and MACE in non-diabetic male patients were higher than those in females.

ABSTRACT

Background@#Despite the increased use of direct-acting oral anticoagulants, warfarin is still recommended as first-line therapy in patients with mechanical valves or moderate to severe mitral stenosis. Anticoagulation management services (AMSs) are warranted for patients receiving warfarin therapy due to the complexity of warfarin dosing and large interpatient variability. To overcome limited health care resources, we developed a messenger app-based chatbot that provides information to patients taking warfarin. @*Methods@#We developed “WafarinTalk” as an add-on to the open-source messenger app KakaoTalk. We developed the prototype chatbot after building a database containing seven categories: 1) dosage and indications, 2) drug-drug interactions, 3) drug-food interactions, 4) drug-diet supplement interactions, 5) monitoring, 6) adverse events, and 7) precautions. We then surveyed 30 pharmacists and 10 patients on chatbot reliability and on participant satisfaction. @*Results@#We found that 80% of the pharmacists agreed on the consistency of chatbot responses and 44% agreed on the appropriateness of chatbot. Furthermore, 47% of pharmacists said that they were willing to recommend the chatbot to patients. Of the seven categories, information on drug-food interaction was the most useful; 90% of patients said they were satisfied with the chatbot and 100% of patients said they were willing to use it when they were unable to see a pharmacist. We updated the prototype chatbot with feedback from the survey. @*Conclusion@#This study showed that warfarin-related information could be provided to patients through a messenger applicationbased chatbot.

ABSTRACT

PURPOSE: This study examined the relationships between nurses' exercise behavior and their anger control using a cross-sectional descriptive design. METHODS: The participants were 290 nurses in South Korea, who completed a survey questionnaire on general characteristics, the stage of exercise behavior change, and anger emotion, evaluated using state anger and anger expression method. RESULTS: Those who engaged in regular exercise behavior exhibited lower levels of state anger and higher levels of anger control than those who did not. In the prediction model, a significant association of exercise behavior with anger control was found. The levels of anger control decreased as the age, education level, and work experiences of nurses decreased. Anger control scores were significantly higher than anger suppression scores and anger expression-out scores in the hospital nurses. CONCLUSION: Engaging in regular exercise may help nurses manage anger emotions better.

ABSTRACT

OBJECTIVES: The Eating Disorder Examination Questionnaire, version 6.0 (EDE-Q version 6.0) and the Clinical Impairment Assessment Questionnaire (CIA) measure attitudes and behavioral features of eating disorders and impairments secondary to eating disorders, respectively. The aims of this study were to examine the reliability and the validity of the Korean versions of the EDE-Q version 6.0 and the CIA. METHODS: Four hundred nineteen participants (370 female university students and 49 women with eating disorders) completed the EDE-Q version 6.0, the CIA, the Body Shape Questionnaire (BSQ) and the Weight Concern Scale (WCS). RESULTS: Excellent internal consistencies were obtained for the EDE-Q version 6.0 (Cronbach's α=0.92) and the CIA (Cronbach's α=0.91). Exploratory factor analysis of CIA extracted the 3 factors of personal, social, and cognitive impairments, as the original CIA had. The EDE-Q version 6.0 and the CIA were well correlated with the BSQ and the WCS, in respect to their contextually concordant variables. Patients with eating disorders had higher scores both in the EDE-Q 6.0 and the CIA than university women had, supporting good discriminant validity. CONCLUSIONS: The EDE-Q version 6.0 and the Korean versions of the CIA had adequate reliability and validity. These data will help clinicians and researchers to use the EDE-Q and the CIA in diagnosis, prevention and intervention of eating disorders in Korea.

ABSTRACT

Recently, epidemiologic studies have shown that the lack of serum vitamin D levels may be associated with high asthma prevalence, but its effect is still controversial, depending on season, area, and food consumption. We aimed to examine the association of serum vitamin D levels with the prevalence of pediatric asthma in Korea. A total of 80 children (50 asthmatic children and 30 healthy controls) aged 6-14 years were participated in this study. Serum vitamin D levels were measured and compared between the two groups. Moreover, the relationship of serum vitamin D levels with results of pulmonary function test and environmental factors (lifestyle habits and residential factors) collected by a questionnaire survey were examined in asthmatic patients. Serum vitamin D levels in asthmatic children (16.63±4.20 ng/mL) were significantly lower than that in healthy controls (24.24±6.76 ng/mL) (p<0.05). Also, we found that the prevalence of asthma increase to 0.79-fold (odds ratio, 0.79; 95% confidence interval, 0.71 to 0.88; p<0.001) as serum vitamin D level is 1 ng/mL decreases. The increased time spent in outdoor could affect the increases of serum vitamin D levels significantly. However, no associations of serum vitamin D with pulmonary function and residential environmental factors (i.e., housing type, living floor, and indoor activity time) were observed. Our findings suggest that serum vitamin D levels were also associated with pediatric asthma in Korea. Moreover, management of serum vitamin D level in asthmatic children would be a promising approach for preventing exaggeration of their severity.

ABSTRACT

OBJECTIVES: Rapid economic growth and industrial development in South Korea have led to a great change in dietary patterns, and the use of convenience foods has continuously increased. This study was performed to evaluate the energy and nutrient contents of convenience foods at convenience stores near the universities as a meal. METHODS: Data was collected by visiting 22 convenience stores near some universities in Chungbuk and Seoul and by checking nutrition labels on convenience foods at the stores. Data of a total of 338 food items were collected, and divided into five groups according to the food categories; rice products (n=156), noodles (n=101), burger/sandwiches (n=62), Tteokbokkis (n=11), and dumplings (n=8). Further, rice products, noodles, and burger/sandwiches were divided into subcategories. RESULTS: The proportion of calories from carbohydrates was high in the rice products and tteokbokki, while the rate of calories from fat was high in burger/sandwiches and dumplings. Among the rice products, the proportion of carbohydrate calories was high in a one-dish food, rice with soup, and triangular kimbap, while the proportion of calories from fat in lunch boxes was high. In the noodles category, ramyeon and spaghetti had a high percentage of fat calories, while udong had a high percentage of carbohydrate calories. The ratio of the calorie content in relation to the KDRIs for adults aged 19-29 years, lunch boxes provided about 1/3 of daily required energy. However, the amount of calories as one meal was not enough for other types of rice products except for lunch boxes. Ramyeon was high in calories, fat, and sodium, but low in protein content. The burger/sandwiches had a high percentage of fat and sodium. CONCLUSIONS: Our results showed several nutritional limitations of convenience meals in convenience stores according to the type of food. Therefore, college students should limit excessive intake of convenience meals on a regular basis in order to avoid unhealthy food intake patterns. Our results demonstrate the need for educating college students with regard to checking nutrition labels when choosing convenience meals in order to facilitate the selection of food items that contribute to a balanced diet.

ABSTRACT

A presumptive diagnosis of bone metastasis can be easily made when a patient with a history of colorectal cancer develops bone lesions that are seen on follow-up imaging. In this case report, we describe a patient whose multiple bone lesions were wrongly attributed to a recurrence of rectal cancer rather than being identified as multiple myeloma lesions. When clinicians detect new, abnormal, bony lesions in a patient with a previous history of cancer, they should consider diseases such as multiple myeloma in their differential diagnosis.

ABSTRACT

OBJECTIVE: If bowels and other structures are in the pathway of high-intensity focused ultrasound (HIFU) beam during magnetic resonance image-guided HIFU (MRgFUS) therapy, filling to the bladder and the rectum and then emptying the bladder (i.e., the BRB technique) is used to avoid them. A modified BRB technique might be useful method to using a uterine elevator method or by inducing uterus downward traction to lower the position of the uterus. METHODS: A total of 156 patients who had undergone MRgFUS surgery treatment for uterine fibroids from March 2015 to February 2016 were included in this retrospective study. Of the 156 patients, 40 were treated using a uterine elevator while 29 were treated using downward traction of uterus. HIFU was performed using Philips Achieva 1.5 Tesla MR and Sonalleve HIFU system. RESULTS: MRgFUS surgery was feasible with modified BRB technique in 69 cases. Using uterine elevator method, the intensity of HIFU for group with antefletxio uteri was significantly lower than that for the group without antefletxio uteri (105.37±17.62 vs. 118.71±26.88 W). The group with downward traction of uterus induced was found to have significantly lower intensity of HIFU compared to the group without downward traction of uterus induced (110.26±22.60 vs. 130.51±27.81 W). CONCLUSION: Modified BRB technique was useful in avoiding bowels and other structures located in HIFU beam pathway during MRgFUS treatment to ablate uterine fibroids.
