RESUMO
BACKGROUND: In Korea, during the early phase of the coronavirus disease 2019 (COVID-19) pandemic, we responded to the uncertainty of treatments under various conditions, consistently playing catch up with the speed of evidence updates. Therefore, there was high demand for national-level evidence-based clinical practice guidelines for clinicians in a timely manner. We developed evidence-based and updated living recommendations for clinicians through a transparent development process and multidisciplinary expert collaboration. METHODS: The National Evidence-based Healthcare Collaborating Agency (NECA) and the Korean Academy of Medical Sciences (KAMS) collaborated to develop trustworthy Korean living guidelines. The NECA-supported methodological sections and 8 professional medical societies of the KAMS worked with clinical experts, and 31 clinicians were involved annually. We developed a total of 35 clinical questions, including medications, respiratory/critical care, pediatric care, emergency care, diagnostic tests, and radiological examinations. RESULTS: An evidence-based search for treatments began in March 2021 and monthly updates were performed. It was expanded to other areas, and the search interval was organized by a steering committee owing to priority changes. Evidence synthesis and recommendation review was performed by researchers, and living recommendations were updated within 3-4 months. CONCLUSION: We provided timely recommendations on living schemes and disseminated them to the public, policymakers and various stakeholders using webpages and social media. Although the output was successful, there were some limitations. The rigor of development issues, urgent timelines for public dissemination, education for new developers, and spread of several new COVID-19 variants have worked as barriers. Therefore, we must prepare systematic processes and funding for future pandemics.

The Korean Medical Association opposes the illegal attempt to implement the physician assistant (PA) system in Korea. The exact meaning of 'PA' in Korea at present time is 'Unlicensed Assistant (UA)' since it is not legally established in our healthcare system. Thus, PA in Korea refers to unlawful, unqualified, auxiliary personnel for medical practitioners. There have been several issues with the illegal PA system in Korea facing medicosocial conflicts and crisis. Patients want to be diagnosed and treated by medically-educated, licensed and professionally trained physicians not PAs. In clinical settings, PAs deprive the training and educational opportunities of trainees such as interns and residents. Recently, there have been several attempts, by CEO or directors of major hospitals in Korea, to adopt and legalize this system without general consensus from medical professional associations and societies. Without such consensus, this illegal implementation of PA system will create new and additional very serious medical crises due to unlawful medical, educational, professional conflicts and safety issues in medical practice. Before considering the implementation of the PA system, there needs to be a convincing justification by solving the fundamental problems beforehand, such as the collapsed medical delivery system, protection and provision of optimal education program and training environment of trainees, burnout from excessive workloads of physicians with very low compensational system and poor conditions for working and education, etc.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has spread around the globe, and it is important to determine the risk factors of death in the general population. Our study aimed to determine the risk factors of death and severe illness requiring supplemental oxygen therapy based on the demographic and clinical characteristics of COVID-19 patients in Korea. METHODS: In this study, we used data provided by the Korea Disease Control and Prevention Agency (KDCA) and analyzed a total of 5,068 patients with COVID-19, excluding 19 pregnant women and 544 individuals with missing data. We performed logistic regression analysis to determine the impact of early symptoms on survival and severe disease. Logistic regression models included sex, age, number of comorbidities, symptoms on admission, blood pressure, heart rate, and body temperature as explanatory variables, and death and oxygen therapy as outcome variables. RESULTS: Logistic regression analyses revealed that the male sex, older age (≥ 60 years), higher number of comorbidities, presence of symptoms on admission, heart rate ≥ 120 bpm, and body temperature ≥ 37.5°C presented with higher risk of in-hospital death and oxygen therapy requirement. Conversely, rhinorrhea and headache were associated with a low risk of death and oxygen therapy requirement. The findings showed that cough, sputum, and fever were the most common symptoms on admission, while 25.3% of patients with COVID-19 were asymptomatic. CONCLUSION: COVID-19 patients with high-risk early symptoms on admission, such as dyspnea and altered mental status, and those without low-risk symptoms of rhinorrhea and headache should be included in priority treatment groups.

OBJECTIVES: To evaluate the clinico-radiological findings of acute fibrinous and organizing pneumonia (AFOP) in the literature according to whether a surgical or non-surgical biopsy was performed, as well as to identify prognostic predictors. METHODS: We searched the Embase and OVID-MEDLINE databases to identify studies that presented CT findings of AFOP and had extractable individual patient data. We compared the clinical and CT findings of the patients depending on whether a surgical or non-surgical biopsy was performed and identified survival predictors using a multivariate logistic regression analysis. RESULTS: Eighty-one patients (surgical biopsy, n = 52; non-surgical biopsy, n = 29) from 63 studies were included. The surgical biopsy group frequently experienced an acute fulminant presentation (p = .011) and dyspnea (p = .001) and less frequently had a fever (p = .006) than the non-surgical biopsy group. The surgical biopsy group had a worse prognosis than the non-surgical biopsy group in terms of mechanical ventilation and mortality (both, p = .023). For survival analysis, the patients with the predominant CT finding of patchy or mass-like air-space consolidation survived more frequently (p < .001) than those with other CT findings. For prognostic predictors, subacute indolent presentation (p = .001) and patchy or mass-like air-space consolidation on CT images (p = .002) were independently associated with good survival. CONCLUSIONS: Approximately one-third of alleged AFOP cases in the literature were diagnosed via non-surgical biopsy, but those cases had different symptomatic presentations and prognosis from surgically proven AFOP. Subacute indolent presentation and patchy or mass-like air-space consolidation at the presentation on CT images indicated a good prognosis in patients with AFOP. KEY POINTS: ⢠Acute fibrinous and organizing pneumonia (AFOP) cases diagnosed via non-surgical biopsy had different symptomatic presentations and prognosis from surgically proven AFOP. ⢠Subacute indolent presentation and patchy or mass-like air-space consolidation on CT images indicated a good prognosis in patients with acute fibrinous and organizing pneumonia.

Coronavirus disease 2019 (COVID-19) has spread widely across the world since January 2020. There are many challenges when caring for patients with COVID-19, one of which is infection prevention and control. In particular, in cases where surgery must absolutely be performed, special infection control may be required in order to perform surgery without spreading infection within the hospital. We aim to present potentially useful recommendations for non-deferrable surgery for COVID-19 patients based on in vivo and in vitro research and clinical experiences from many countries.

A clinical practice guideline for patients in the dying process in general wards and their families, developed through an evidence-based process, is presented herein. The purpose of this guideline is to enable a peaceful death based on an understanding of suitable management of patients' physical and mental symptoms, psychological support, appropriate decision-making, family care, and clearly-defined team roles. Although there are limits to the available evidence regarding medical issues in patients facing death, the final recommendations were determined from expert advice and feedback, considering values and preferences related to medical treatment, benefits and harms, and applicability in the real world. This guideline should be applied in a way that takes into account specific health care environments, including the resources of medical staff and differences in the available resources of each institution. This guideline can be used by all medical institutions in South Korea.
RESUMO
BACKGROUND: Proper education regarding inhaler usage and optimal management of chronic obstructive pulmonary disease (COPD) is essential for effectively treating patients with COPD. This study was conducted to evaluate the effects of a comprehensive education program including inhaler training and COPD management. METHODS: We enlisted 127 patients with COPD on an outpatient basis at 43 private clinics in Korea. The patients were educated on inhaler usage and disease management for three visits across 2 weeks. Physicians and patients were administered a COPD assessment test (CAT) and questionnaires about the correct usage of inhalers and management of COPD before commencement of this program and after their third visit. RESULTS: The outcomes of 127 COPD patients were analyzed. CAT scores (19.6±12.5 vs. 15.1±12.3) improved significantly after this program (p<0.05). Patients with improved CAT scores of 4 points or more had a better understanding of COPD management and the correct technique for using inhalers than those who did not have improved CAT scores (p<0.05). CONCLUSION: A comprehensive education program including inhaler training and COPD management at a primary care setting improved CAT scores and led to patients' better understanding of COPD management.
RESUMO
BACKGROUND: A well-organized education program improved the patients' knowledge about their disease, inhaler technique and quality of life in asthma and chronic obstructive pulmonary disease (COPD) patients. The effectiveness of the education program can be evaluated by assessing patients' satisfaction with the education program as well. In this study, we compared the patients' satisfaction with education program between COPD and asthma patients. METHODS: A total of 284 asthma and COPD patients were enrolled. Three educational visits were conducted at 2-week intervals. On the first visit, we taught the patients about their diseases and the proper inhaler technique. On the second visit, non-pharmacologic treatments and action plans for acute exacerbation were introduced. On the final appointment, we summarized the educational concepts covered in the two prior visits. After the education program, the patients were assessed for their quality of life, knowledge of chronic airways disease, and satisfaction with the education program, using a structured questionnaire. RESULTS: After the education program, 99.3% of the asthma patients knew much more about their disease and 96.8% agreed that education from the hospital is needed. For COPD patients, 94.8% felt more informed about their disease and 95.7% agreed that education from the hospital is needed. However, 17.1% of asthma patients and 13.5% of COPD patients disagreed to paying an additional fee for the education program. Finally, the knowledge improvement was linked to patient satisfaction with the education program. CONCLUSIONS: The improvement in self-knowledge about their disease was linked to their satisfaction with the education program. However, costs associated with the program could limit its accessibility to the patients. The patient education program is a self-management intervention to improve the lives of patients with asthma and COPD. Thus, a policy to reduce the economic burden of the patients should be considered to disseminate the education program in primary care clinics.
RESUMO
BACKGROUND: The purpose of this study was to assess the effect of our new video-assisted asthma education program on patients' knowledge regarding asthma and asthma control. METHODS: Adult asthmatics who were diagnosed by primary care physicians and followed for at least 1 year were educated via smart devices and pamphlets. The education sessions were carried out three times at 2-week intervals. Each education period lasted at most 5 minutes. The effectiveness was then evaluated using questionnaires and an asthma control test (ACT). RESULTS: The study enrolled 144 patients (mean age, 56.7±16.7 years). Half of the patients had not been taught how to use their inhalers. After participating in the education program, the participants' understanding of asthma improved significantly across all six items of a questionnaire assessing their general knowledge of asthma. The proportion of patients who made errors while manipulating their inhalers was reduced to less than 10%. The ACT score increased from 16.6±4.6 to 20.0±3.9 (p<0.001). The number of asthmatics whose ACT score was at least 20 increased from 45 (33.3%) to 93 (65.3%) (p<0.001). The magnitude of improvement in the ACT score did not differ between patients who received an education session at least three times within 1 year and those who had not. The majority of patients agreed to the need for an education program (95.8%) and showed a willingness to pay an additional cost for the education (81.9%). CONCLUSION: This study indicated that our newly developed education program would become an effective component of asthma management in primary care clinics.
RESUMO
BACKGROUND: Inhaled indacaterol (Onbrez Breezhaler), a long-acting ß2-agonist, is approved in over 100 countries, including South Korea, as a once-daily bronchodilator for maintenance and treatment of chronic obstructive pulmonary disease (COPD). Here, we present an interim analysis of a post-marketing surveillance study conducted to evaluate the real-world safety and effectiveness of indacaterol in the Korean population. METHODS: This was an open-label, observational, prospective study in which COPD patients, who were newly prescribed with indacaterol (150 or 300 µg), were evaluated for 12 or 24 weeks. Safety was assessed based on the incidence rates of adverse events (AEs) and serious adverse events (SAEs). Effectiveness was evaluated based on physician's assessment by considering changes in symptoms and lung function, if the values of forced expiratory volume in 1 second were available. RESULTS: Safety data were analyzed in 1,016 patients of the 1,043 enrolled COPD patients receiving indacaterol, and 784 patients were included for the effectiveness analysis. AEs were reported in 228 (22.44%) patients, while 98 (9.65%) patients reported SAEs. The COPD condition improved in 348 patients (44.4%), while the condition was maintained in 396 patients (50.5%), and only 40 patients (5.1%) exhibited worsening of ailment as compared with baseline. During the treatment period, 90 patients were hospitalized while nine patients died. All deaths were assessed to be not related to the study drug by the investigator. CONCLUSION: In real-life clinical practice in South Korea, indacaterol was well tolerated in COPD patients, and can be regarded as an effective option for their maintenance treatment.
RESUMO
Education has been known to essential for management of chronic airway diseases. However the real benefits remain unclear. We evaluated the effectiveness of an organized educational intervention for chronic airway diseases directed at primary care physicians and patients. The intervention was a 1-month education program of three visits, during which subjects were taught about their disease, an action plan in acute exacerbation and inhaler technique. Asthma control tests (ACT) for asthma and, chronic obstructive pulmonary disease (COPD) assessment tests (CAT) for COPD subjects were compared before and after education as an index of quality of life. Educational effectiveness was also measured associated with improvement of their knowledge for chronic airway disease itself, proper use of inhaler technique, and satisfaction of the subjects and clinicians before and after education. Among the 285 participants, 60.7% (n = 173) were men and the mean age was 62.2 ± 14.7. ACT for asthma and CAT in COPD patients were significantly improved by 49.7% (n = 79) and 51.2% (n = 65) more than MCID respectively after education (P < 0.05). In all individual items, knowledge about their disease, inhaler use and satisfaction of the patients and clinicians were also improved after education (P < 0.05). This study demonstrates the well-organized education program for primary care physicians and patients is a crucial process for management of chronic airway diseases.

Spontaneous pneumomediastinum (PM) is an uncommon condition in which free air enters the mediastinum. This usually occurs either through esophageal tears after vigorous vomiting, or after alveolar rupture subsequent to a rapid increase in intra-alveolar pressure. Spontaneous PM is a rare entity in anorexia nervosa (AN) and self-induced vomiting is often the cause of PM in patients with AN. We experienced a case of spontaneous PM in an anorexic adolescent, in whom vomiting was not the cause of PM.
RESUMO
Patients admitted to medical intensive care unit (MICU) are at increased risk for venous thromboembolism (VTE); and prophylaxis is recommended. However, the actual range and frequency of VTE prophylaxis administered to MICU patients are not well defined. Patients over 40 yr of age and expected MICU stay of more than 48 hr were eligible for this observational cohort study of 23 MICUs in Korea. Patients already on anticoagulation therapy or those requiring anticoagulation for reasons other than VTE were excluded. Among 830 patients, VTE prophylaxis was given to 560 (67.5%) patients. Among 560 patients, 323 (38.9%) received pharmacoprophylaxis, 318 (38.4%) received mechanical prophylaxis and 81 (9.8%) received both forms of prophylaxis. About 74% of patients in the pharmacoprophylaxis group received low molecular weight heparin and 53% of the patients in the mechanical prophylaxis group used intermittent pneumatic compression. Most of the patients (90%) had more than one risk factor for VTE and the most common risk factor was old age, followed by heart and respiratory failure. In this observational cohort study of 23 MICUs in Korea, 67.5% of patients received thromboprophylaxis. Further studies are needed to clarify the role and efficacy of VTE prophylaxis in Korean critically ill patients.

BACKGROUND: Pseudomonas aeruginosa infection is particularly associated with progressive and ultimately chronic recurrent respiratory infections in chronic obstructive pulmonary disease, bronchiectasis, chronic destroyed lung disease, and cystic fibrosis. Its treatment is also very complex because of drug resistance and recurrence. METHODS: Forty eight cultures from 18 patients with recurrent P. aeruginosa pneumonia from 1998 to 2002 were included in this study. Two or more pairs of sputum cultures were performed during 2 or more different periods of recurrences. The comparison of strains was made according to the phenotypic patterns of antibiotic resistance and chromosomal fingerprinting by pulsed field gel electrophoresis (PFGE) using the genomic DNA of P. aeruginosa from the sputum culture. RESULTS: Phenotypic patterns of antibiotic resistance of P. aeruginosa were not correlated with their prior antibiotic exposition. Fifteen of 18 patients (83.3%) had recurrent P. aeruginosa pneumonia caused by the strains with same PFGE pattern. CONCLUSION: These data suggest that the most of the recurrent P. aeruginosa infections in chronic lung disease occurred due to the relapse of prior infections. Further investigations should be performed for assessing the molecular mechanisms of the persistent colonization and for determining how to eradicate clonal persistence of P. aeruginosa.
RESUMO
BACKGROUND: In Korea, patients with destroyed lung due to tuberculosis (TB) account for a significant portion of those affected by chronic pulmonary function impairment. The objective of our research was to evaluate the efficacy of inhaled tiotropium bromide in TB destroyed lung. METHODS: We compared the effectiveness of inhaled tiotropium bromide for 2 months between pre- and post-treatment pulmonary function tests performed on 29 patients with destroyed lung due to TB. RESULTS: The mean age of the total number of patients was 63±9 years, where 15 patients were male. The pre-treatment mean forced expiratory volume in 1 second (FEV1) was 1.02±0.31 L (44.1±16.0% predicted). The pre-treatment mean forced vital capacity (FVC) was 1.70±0.54 L (52.2±15.8% predicted). Overall, the change in FEV1% predicted over baseline with tiotropium was 19.5±19.1% (p<0.001). Twenty patients (72%) got better than a 10% increase in FEV1 over baseline with tiotropium, but one patient showed more than a 10% decrease in FEV1. Overall, the change in FVC% predicted over baseline with tiotropium was 18.5±19.9% (p<0.001). Seventeen patients (59%) experienced greater than a 10% increase in FVC over baseline with tiotropium; 12 (41%) patients had stable lung function. CONCLUSION: The inhaled tiotropium bromide therapy may lead to improve lung functions in patients with TB destroyed lung. However, the long-term effectiveness of this treatment still needs to be further assessed.
RESUMO
Sex and sex hormones play a major role in lung physiology. It has been proposed that the ratio of the second to fourth digits (digit ratio) is correlated with fetal sex hormones. We therefore hypothesized that digit ratio might help predict lung function. We investigated the relationship between digit ratio and pulmonary function test (PFT) findings. A total of 245 South Korean patients (162 male, 83 female) aged from 34 to 90 years who were hospitalized for urological surgery were prospectively enrolled. Before administering the PFTs, the lengths of the second and fourth digits of the right hand were measured by a single investigator using a digital Vernier caliper. In males (n = 162), univariate and multivariate analysis using linear regression models showed that digit ratio was a significant predictive factor of forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) (FVC: r = 0.156, P = 0.047; FEV1: r = 0.160, P = 0.042). In male ever-smokers (n = 69), lung functions (FVC and FEV1) were correlated with smoking exposure rather than digit ratio. In female never-smokers (n = 83), lung functions (FEV1 and FEV1/FVC ratio) were positively correlated with digit ratio on univariate analysis (FEV1: r = 0.242, P = 0.027; FEV1/FVC ratio: r = 0.245, P = 0.026). Patients with lower digit ratios tend to have decreased lung function. These results suggest that digit ratio is a predictor of airway function.

Tako-Tsubo cardiomyopathy (TTC), also known as transient left ventricular (LV) ballooning syndrome or stress-induced cardiomyopathy, is characterised by transient LV dysfunction in the absence of significant angiographic coronary stenoses, frequently provoked by an episode of emotional or physical stress. In TTC, typically transient akinesis or dyskinesis of the LV apical segments with normal or hypercontractile basal wall motions is observed. Recently, several cases of atypical or inverted transient TTC sparing the LV apex have been reported. We report a case of inverted TTC showing akinesis of the basal and mid-ventricular segments of the LV with apical hyperkinesia triggered by bronchoscopy with bronchoalveolar lavage.

In 2007, the Korean Interstitial Lung Disease Society had collected clinical data of patients who have diagnosed as Lymphangioleiomyomatosis (LAM) since 1990 through nationwide survey, which showed that LAM patients had increased sharply after 2004. The present study was performed to show the clinical features of Korean patients with LAM, and to establish the reason for the recent increase in the diagnosis. All 63 patients were women and the mean age at diagnosis was 36 yr. The most common presenting symptom was dyspnea and 8 patients had tuberous sclerosis complex. The survival rate at 5 yr after diagnosis was 84%. Compared with patients diagnosed after 2004 (n=34), the patients diagnosed before 2004 (n=29) complained with dyspnea more (P=0.016) and had lower FEV(1)% predicted (P=0.003), and DLco% predicted (P=0.042). The higher proportion of patients diagnosed after 2004 showed the normal chest radiography, and they were detected by routine chest CT screening (P=0.016). This study showed that clinical features of Korean patients with LAM were not different from those reported elsewhere. It is concluded that the reason for the increase of newly diagnosed patients is the result of increase in detection of the early stage LAM by the widespread use of chest CT screening.
