In this study, we analyzed the healthcare system of North Korea using Kleczkowski's model which categorizes national healthcare infrastructure into five components: health resources, organization, healthcare delivery system, economic support, and management. It was found that the healthcare system in North Korea, which provides clinical medicine, Koryo medicine and preventive medicine, is constituted of a physician system of independent geographic sectors and centralized delivery system while maintaining free universal health coverage. These systems are all managed by the government and the People's Committee Party. However, North Korea has been confronted with severe economic difficulties since the 1990s, such that we question whether the healthcare system has been able to function properly despite of the lack of resources in general throughout the country.

The incidence and mortality rate of cancer continues to gradually increase, although considerable research effort has been directed at elucidating the molecular mechanisms underlying biomarkers responsible for tumorigenesis. Accumulated evidence indicates that the long non-coding RNAs (lncRNAs), which are transcribed but not translated into functional proteins, contribute to cancer development. Recently, linc00152 (an lncRNA) was identified as a potent oncogene in various cancer types, and shown to be involved in cancer cell proliferation, invasiveness, and motility by sponging tumor-suppressive microRNAs acting as a competing endogenous RNA, binding to gene promoters acting as a transcriptional regulator, and binding to functional proteins. In this review, we focus on the oncogenic role of linc00152 in tumorigenesis and provided an overview of recent clinical studies on the effects of linc00152 expression in human cancers.

Since lung cancer is a major causative for cancer-related deaths, the investigations for discovering biomarkers to diagnose at an early stage and to apply therapeutic strategies have been continuously conducted. Recently, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) are being exponentially studied as promising biomarkers of lung cancer. Moreover, supportive evidence provides the competing endogenous RNA (ceRNA) network between lncRNAs and miRNAs participating in lung tumorigenesis. This review introduced the oncogenic or tumor-suppressive roles of lncRNAs and miRNAs in lung cancer cells and summarized the involvement of the lncRNA/miRNA ceRNA networks in carcinogenesis and therapeutic resistance of lung cancer.

Systems thinking, a linking domain of health systems science (HSS), is an approach that investigates specific problems from a holistic perspective. It supports improving patients’ health, fulfilling their health needs, and anticipating issues that threaten patient safety within the healthcare system. It also helps solve problems through critical thinking and reflection. This study aimed to develop an curriculum on systems thinking, explore the effectiveness of the course, and investigate the applicability of HSS education at individual universities. In this study, the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model was utilized to design, develop, implement, and evaluate an elective course on systems thinking. In the design process, learning outcomes and goals were developed, and educational content, teaching-learning methods, and student evaluation methods were linked. In the development process, class materials and evaluation materials were prepared. In the implementation process, the course was implemented, and the evaluation process analyzed the results of learning performance and curriculum assessments. The evaluation found the following results. First, the students in the study realized the importance of systems thinking and experienced the need for systems thinking through non-medical and medical situations. Second, the students were very satisfied with the learning activities in the course (mean=4.84), and the results of the self-competence evaluation, conducted before and after the course, also showed a significant improvement. This study confirmed the effectiveness of the elective course, and its results can serve as a reference for developing an HSS curriculum .

Purpose:
Meconium aspiration syndrome (MAS) occurs when aspiration of meconium itself or meconium-stained amniotic fluid enters into the airways. The relationship between MAS and how they affect the respiratory outcome after recovery from MAS remains unknown. The purpose of this study was to determine the type of lower respiratory tract illness (LRTI) in those surviving MAS survivors and to find out whether any clinical findings or treatment determine the type of LRTI.
Methods:
We used the Catholic Medical Center’s clinical data warehouse to review data from 4 university hospitals. We first included 1,331 newborns born between March 2016 and February 2021 with diagnostic codes including labor and delivery complicated by fetal stress (distress), intrauterine hypoxia, and neonatal aspiration syndromes. We finally included 239 patients who visited the outpatient clinic with diagnosis of pneumonia, acute bronchitis, acute bronchiolitis, and asthma, according to the Korean Standard Classification of Diseases.
Results:
We observed a significantly higher number and fraction of eosinophils at birth in the bronchitis group. We also found significantly lower levels of white blood cells in the asthma group. After a regression analysis, we found that mechanical ventilation and steroid usage for treatment for of MAS was significantly related to bronchitis, and that antibiotics treatment acted as a protective factor for bronchiolitis.
Conclusion
Laboratory findings and treatment at birth in infants with MAS appear to have impact on determining LRTI in those who survived MAS.

Multisystem inflammatory syndrome in children (MIS-C) is a serious post-infectious complication of COVID-19 characterized by hyperinflammation and multi-organ dysfunction including shock. Shock is also seen in a severe form of Kawasaki disease (KD) called KD shock syndrome (KDSS). Here, we present one MIS-C and one KDSS case and compare similarities and differences between them. Both MIS-C (case 1) and KDSS (case 2) showed hyperinflammation, KD-related features, gastrointestinal problems, hypotension, and coagulopathy. The extent of systemic inflammation and organ dysfunction was more severe in KDSS than in MIS-C. Case 1 was diagnosed as MIS-C because SARS-CoV-2 was confirmed, and case 2 was diagnosed as KDSS because no pathogen was identified in microbiological studies. We believe that the most important difference between MIS-C and KDSS was whether SARS-CoV-2 was identified as an infectious trigger. Organ dysfunction is a hallmark of MIS-C and KDSS, but not KD, so MIS-C shares more clinical phenotypes with KDSS than with KD. Comparison of MIS-C and KDSS will be an interesting and important topic in the field of KD-like hyperinflammatory disease research.

Background:
Unemployment and the consequential mental health issues are emerging as a major social concern. This study aimed to evaluate factors associated with depression and suicidality among unemployed individuals in the Jeju area.
Methods:
Data from 624 unemployed adults who participated in a community survey were analyzed. Self-report questionnaires were completed by all participants; demographic variables and the Patient Health Questionnaire-9 were used to assess depression. The Mini International Neuropsychiatric Interview suicidality module was used to obtain information regarding suicidal ideation, suicide plans, and suicide attempts.
Results:
The prevalence of depressive symptoms among the unemployed population in Jeju area was 28.4%. Factors associated with suicidality included age, gender, unemployment period, job application period, and depression. Furthermore, unemployed participants who had an opportunity to receive vocational education had fewer symptoms of depression regardless of the number of vocational education sessions. A multivariate regression model demonstrated that depression (β = 0.51, p<0.001) was significantly correlated with suicidality.
Conclusion
The findings advance our understanding of the relationship between unemployment and psychological factors such as depression symptoms and suicidality. Further studies are required to determine the underlying mechanisms to aid in the development of preventive and treatment strategies.

Being born small for gestational age (SGA) has been strongly associated with mortality during the perinatal period and long-term risk of metabolic syndrome, including type 2 diabetes mellitus, hypertension, hyperlipidemia, and coronary heart disease. Insulin resistance is an important factor in the development of metabolic syndrome in SGA, with several proposed hypotheses. Here, we report two cases of non-obese adolescent patients with early onset type 2 diabetes who were born SGA. Of these, one experienced catch-up growth, while the other did not. Both had a high body fat percentage at the time of diagnosis of type 2 diabetes and were diagnosed with fatty liver and hyperlipidemia before adolescence, at the age of 7 years. Early interventions for SGA are needed for healthy catch-up growth to prevent metabolic diseases in the future.
