BACKGROUND: In the wake of the coronavirus disease 2019 (COVID-19) pandemic, people need to practice social distancing in order to protect themselves from SARS-CoV-2 infection. In such stressful situations, remote cardiac rehabilitation (CR) might be a viable alternative to the outpatient CR program. METHODS: We prospectively investigated patients hospitalized for heart failure (HF) with a left ventricular ejection fraction of < 50%. As for patients who participated in the remote CR program, telephone support was provided by cardiologists and nurses who specialized in HF every 2 weeks after discharge. The emergency readmission rate within 30 days of discharge was compared among the outpatient CR, remote CR, and non-CR groups, and the EQ-5D score was compared between the outpatient CR and remote CR groups. RESULTS: The participation rate of HF patients in our remote CR program elevated during the COVID-19 pandemic. As observed in the outpatient CR group (n = 69), the emergency readmission rate within 30 days of discharge was lower in the remote CR group (n = 30) than in the non-CR group (n = 137) (P = 0.02). The EQ-5D score was higher in the remote CR group than in the outpatient CR group (P = 0.03) 30 days after discharge. CONCLUSIONS Remote CR is as effective as outpatient CR for improving the short-term prognosis of patients hospitalized for heart failure post-discharge. This suggests that the remote CR program can be provided as a good alternative to the outpatient CR program.

OBJECTIVES: Numerous studies have been reported on the effect of customized vestibular exercise (cVE), but only a few studies have been reported on the satisfaction of cVE. Therefore, this study aims to investigate the factors that affect the satisfaction of cVE. METHODS: A telephone survey was conducted on 37 patients who underwent cVE from January to November 2018. The questionnaire consisted of a total of 10 items, including subjective symptom, compliance and satisfaction of exercise, preferred methods of exercise, and appropriate costs. Based on the questionnaire of satisfaction, the clinical features, improvement of symptom, compliance, preferred methods of exercise were compared between satisfactory and unsatisfactory groups. RESULTS: Of the 20 patients who responded to the telephone survey (response rate 57%), 10 patients were included in the satisfactory group and the remaining 10 were included in the unsatisfactory group. There were no significant differences between the 2 groups in age, sex, severity of subjective symptom before cVE, preferred methods of exercise. However, patients in the unsatisfactory group were significantly more likely to have chronic vestibulopathy and abnormal findings in dynamic posturography test than those in the satisfactory group. Subjective dizziness after cVE was significantly decreased in the satisfactory group, but there was no significant difference in the unsatisfactory group. These patients in the unsatisfactory group still had dizziness, but tended not to continue to exercise. CONCLUSIONS: The satisfaction of cVE was significantly lower in patients with chronic vestibulopathy, postural instability, less improvement of dizziness, and poor compliance.

Mortalities from cardiovascular disease in Korea have decreased markedly over the past three decades. The major cardiovascular and metabolic risk factors, however, remain prevalent, and their burden on health is large. The Cardiovascular and Metabolic Diseases Etiology Research Center (CMERC) planned a cohort study in order to identify novel risk factors and to develop evidence-based prevention strategies of cardiovascular and metabolic diseases. The CMERC deliberately designed two prospective cohorts, a community-based general population cohort (the CMERC cohort) and its sister cohort (a hospital-based high-risk patient cohort), covering a broad spectrum of cardiovascular and metabolic diseases. This paper describes the CMERC cohort study of community-dwelling adults aged 30 to 64 years. A total of 8097 adults completed baseline measurement between 2013 and 2018. Baseline measurements assessed socio-demographic factors, medical history, health-related behaviors, psychological health, social network and support, anthropometry, body composition, and resting blood pressure and comprised electrocardiography, carotid artery ultrasonography, fasting blood analysis, and urinalysis. Both active follow-up through an annual telephone survey and a 5-year on-site health examination survey and passive follow-up through secondary data linkage with national databases, such as national death records, have been applied. Researchers interested in collaborative research may contact the corresponding author.

BACKGROUND AND OBJECTIVES: Chronic pediatric sinusitis continues to be a challenging problem to otolaryngologists and has been reported to show worse prognosis than that of adults. However, most studies were performed with short-term follow-up. In this study, we aimed to assess the clinical outcome of pediatric endoscopic sinus surgery (ESS) with a longer follow-up and to determine the effect of age on postoperative outcome. SUBJECTS AND METHOD: A retrospective analysis was performed on pediatric patients than 15 years with ESS younger from 2005 to 2014 in a tertiary referral hospital. All patients completed a questionnaire regarding symptoms before to from 1 to 9 years after surgery. Telephone survey was performed to evaluate symptoms including nasal obstruction, nasal discharge, PND, and headache at 1 to 9 years after surgery. RESULTS: Seventy-one pediatric patients with bilateral chronic sinusitis were treated with ESS. They showed gradual symptom improvement from 5 year after surgery for the following: nasal obstruction (p=0.032), PND (p=0.005), and headache (p=0.048). However, there was improvement in rhinorrhea after 9 years (p=0.042). In addition, when analyzed in terms of age, the outcome was poor in children younger than 13 years (p=0.003) compared with the older age group. Multivariate analysis showed that preoperative nasal obstruction was dependent on AR, and postoperative symptoms were dependent on presence of AR and involuntary smoking. Nasal discharge was dependent on presence of AR and involuntary smoking preoperatively and postoperatively. These suggest the importance of AR and involuntary smoking as risk factors for prognosis. CONCLUSION: Chronic pediatric sinusitis showed gradual improvement after ESS and should be more carefully monitored on a long-term basis. We should keep in mind that long-term follow-up is needed for pediatric ESS cases.

PURPOSE: The vaccination level of rotavirus vaccine not supported by the government is not known. As vaccines not included in the national immunization schedule are not registered in the computerized national immunization registry system, their vaccination rate cannot be calculated according to the same method used in government-supported vaccines. Therefore, this study aimed to measure the status of the vaccination rate of rotavirus not included in the national immunization schedule. METHODS: The target population is the 0-year-old cohort. The survey population was composed of registered children born in 2017 enrolled in the Immunization Registry Information System. The survey was conducted through a computerized telephone survey method. The survey variables were as follows: vaccination order and date, provider, and data source. Factors related to complete vaccination were the child's sex, residence, birth order, and parents' age, educational level, and job status. RESULTS: Children's vaccination rates for the rotavirus vaccine by 2017 were 88.0%, 86.9%, and 96.6% for the first, second, and third doses, respectively. The rate of complete vaccination was 85.6%. The factors related to rotavirus complete vaccination were the child's sex and birth order, area of residence, parents' age and job status, and father's education level. CONCLUSION: In the future, it is necessary to conduct regular investigations on the rate of rotavirus vaccination as a tool for the development of the rotavirus infectious diseases control policy or as an evaluation tool for vaccine programs.

BACKGROUND: Several studies have evaluated risk factors for falls; however, the risk factors for recurrent falls are poorly understood. Therefore, this study evaluated the prevalence and factors associated with recurrent falls.METHODS: This study included 250 patients aged over 65 years, all of whom visited the emergency department (ED) at Seoul Medical Center following a fall from January 2016 to December 2017. We reviewed the patients' medical records for demographic data and medical history. Previous fall history, use of gait-aids, residence type, and fall recurrence were assessed via individual telephone calls.RESULTS: During the follow-up period, 21.6% (n=54) of the 250 subjects experienced recurrent falls. Logistic regression analyses showed that fall recurrence was significantly associated with a previous fall history and the residence type. Subjects who lived in basement-level residences had a significantly higher risk of fall recurrence compared to those who lived in ground-level residences (odds ratio, 8.910; 95% confidence interval, 1.082–73.366).CONCLUSION: This study revealed a high incidence of fall recurrence in older adults who visited the ED due to falls. Our results suggest that careful evaluation and intervention are essential, especially in elderly individuals with fall histories and those who live in residences associated with ncreased risk of falls.

BACKGROUND: Although the number of medical institutions running a smoking cessation clinic is on the rise, there remains a paucity of research on the long- and short-term success rates of smoking cessation programs, as well as on smoking relapse rates, before and after project implementation. This study assessed the general characteristics of patients visiting the smoking cessation clinic, success rate of smoking cessation in the short term, and risks of relapse. METHODS: Medical records from March 2015 to April 2017 were analyzed and telephone surveys were conducted with 151 smokers who visited a hospital smoking cessation clinic from March 2015 to April 2017. RESULTS: Of the 139 smokers who were eligible for follow-up, 22 (15.8%) failed to quit smoking initially. The clinic's 6-month success rate of smoking cessation was 64.83%. Those with higher medication compliance had a lower risk of primary failure (odds ratio, 0.056; 95% confidence interval, 0.005–0.609), whereas those with higher age (hazard ratio [HR], 0.128; P=0.0252) and a greater number of visits to the clinic (HR, 0.274; P=0.0124) had a lower risk of relapsing. CONCLUSION: The risk of primary failure to quit was higher with low medication compliance, and that of relapsing was higher with lower age and fewer number of clinic visits. Various evaluation and analysis methods can be carried out in the future based on the accumulated data for maintenance of smoking cessation and relapse prevention.

BACKGROUND: Although guidelines to prevent surgical site infections (SSIs) were published more than a decade ago, prophylactic antibiotics are still used subjectively in clinical practice. In this study, we evaluated the safety of single-dose preoperative intravenous antibiotics without postoperative antibiotics in the field of clean wound surgery performed under local anesthesia. We also surveyed the present clinical conditions for prophylactic antibiotic use in the plastic surgery departments of training hospitals in Korea. METHODS: A total of 360 consecutive patients who underwent clean wound surgery under local anesthesia in an outpatient clinic from March 2018 to October 2018 were reviewed. In the study group, a single surgeon administered first-generation cephalosporins intravenously within 1 hour of skin incision and did not prescribe additional antibiotics. In the control group, 2 other surgeons prescribed oral first-generation cephalosporins postoperatively for 2 to 3 days without preoperative antibiotics. A telephone survey about perioperative antibiotic regimens was conducted at the departments of plastic surgery in training hospitals. RESULTS: There were 128 patients in the study group and 232 patients in the control group. There were no significant differences between the 2 groups regarding SSIs and other surgical complications. A total of 41 training hospitals answered the survey and every hospital had protocols of prescribing postoperative oral antibiotics routinely at the time of discharge with a mean duration of 3.9 days. Only 11 hospitals (26.8%) prescribed parenteral antibiotics before surgery as well as postoperative oral antibiotics. CONCLUSION: Intravenous injection of single-dose first-generation cephalosporins 1 hour before surgery without postoperative antibiotics did not increase the incidence of SSIs compared with the usual practice of giving only postoperative antibiotics prescription for 2 to 3 days in cases of clean wound surgery performed under local anesthesia. Proper antibiotic prophylaxis should be performed by surgeons in training hospitals without hesitation.

OBJECTIVE: This study aimed to assess the surgical results of the intradural transpetrosectomy for petrous apex meningiomas (PAMs). In addition, we describe the methods and techniques used to expose and manage superior petrous vein and greater superficial petrosal nerve.METHODS: The authors conducted a retrospective study of 16 patients with PAMs operated by the senior author via the intradural transpetrosectomy between February 2012 to May 2017. We reviewed patient data regarding the general characteristics, surgical technique and surgery-related outcomes and adopted a combined follow-up strategy of clinic and telephone contacts to evaluate postoperative complications.RESULTS: Simpson grade I and II resection was performed in 10 out of 16 cases (62.5%), and grade III resection were reported in the remaining six cases (37.5%) with no resultant mortality. The mean Karnofsky Performance Status score was 85.6 preoperatively and improved to 91.9 postoperatively, with a mean follow-up period of 34.4 months (range, 6–66 months). Tumor recurrence was found in two patients and they underwent the second surgical operation.CONCLUSION: PAMs could be completely resected by the intradural transpetrosectomy with an improved survival rate and postoperative life quality. Superior petrous vein and greater superficial petrosal nerve should be managed properly in avoidance of postoperative complications. Finally, most meningioma inside cavernous sinus or adhered to brainstem could be totally removed without postoperative complications.

BACKGROUND/AIMS: Behavioral factors, such as smoking and heavy alcohol consumption, increase the risk of gastric cancer (GC), but their effects on survival are not clear. We examined associations between prediagnostic smoking and alcohol drinking behavior and GC death by long-term follow-up. METHODS: The participants were 508 GC patients enrolled at Chungnam University Hospital and Hanyang University Guri Hospital from 2001 to 2006. Information on clinicopathologic and behavioral risk factors was collected, and patient survival was prospectively followed until 2016 by medical chart review and telephone survey. RESULTS: During above 10 years follow-up period, overall death was 46.2% (n=226) and GC deaths was 38.2% (n=187) among the 489 GC patients included in the analysis. No significant association was found between smoking habits and overall or GC survival. However, after stratification by histological type, the hazard ratio (HR) of GC death for current smokers tended to be higher for the diffuse type (HR 1.61, 95% CI 0.57–4.59 for current vs. never) rather than for the intestinal type (HR 0.78, 95% CI 0.28–2.19 for current vs. never). Light alcohol consumption was found to be associated with a significantly lower risk of GC death (HR 0.52, 95% CI 0.36–0.75 for <20 g/day for women or <40 g/day for men vs. never and past), and the effects of alcohol drinking habits had similar effects on GC death for the intestinal and diffuse types. CONCLUSIONS: These results suggest smoking and alcohol drinking behaviors before a diagnosis of GC are weakly associated with GC survival. Nevertheless, the effect of smoking behavior on prognosis appears to depend on the histological type of GC.
