OBJECTIVE:
The purpose of this study was to establish the prevalence of PTSD among North Korean defectors who visited the National Medical Center, Seoul, South Korea over a period of approximately 10 years by examining their medical records and to examine differences in the medical service usage patterns of patients with and without PTSD.
METHODS:
Data from North Korean defectors who used outpatient services at the National Medical Center during a period of 10 years and 3 months (January 1 2006 to February 28, 2016) were analyzed. The general characteristics of the defectors were analyzed by frequency analyses, and descriptive statistics were generated. Additionally, independent t-tests and chi square analyses were performed to examine differences between PTSD patients and those without PTSD. Linear regression analysis was performed to examine factors affecting the mental health of North Korean defectors suffering from PTSD.
RESULTS:
This study assessed the correlations between PTSD, the average number of outpatient visits, and the total revenue. The regression analysis showed a relationship between PTSD and the average number of outpatient visits. There was also a correlation between PTSD and total revenue. The average number of outpatient visits was 41.8 for PTSD patients, whereas it was 33.2 for those without PTSD. The total revenue visit was 953.6 USD for PTSD sufferers and 231.1 USD for those without PTSD.
CONCLUSION
This study found that the majority of North Korean defectors visit psychiatry departments, and that PTSD patients use outpatient services more frequently and have higher total revenue than those without PTSD. Additionally, patients with PTSD used a greater variety of medical services. Considering the high medical care expenses of North Korean defectors residing in South Korea, future investigations should examine the medical service usage patterns of such patients, especially those diagnosed with PTSD, in greater detail.

OBJECTIVES:
Secondhand smoke is an issue that cannot be ignored due to its various negative effects. Especially, secondhand smoke inside the household is an area where health policy must pay attention as it can affect all age groups. This study aims to identify the factors associated with smoking inside the household focusing on socioeconomic status in Korea.
METHODS:
We used data from the Community Health Survey of 2017 and a total of 33,462 participated in the study. Data were analyzed through IBM SPSS version 25.0 to conduct binary logistic regression analysis.
RESULTS:
Results indicated that indoor smoking had a significant association with socioeconomic status. This association was more marked in those participants who had low household income or those with elementary school education level or less. Furthermore, the study indicates that when the smoker is a woman, older, has higher stress, and is a heavier smoker, the probability of her smoking inside the house is higher.
CONCLUSIONS
Based on the results, it is meaningful that this study has found the factors of smoking inside household. The result identify the factors associated with indoor smoking at home, and it can be used as baseline data for developing new smoking cessation policies.

4.Updates on Genetic Hearing Loss: From Diagnosis to Targeted Therapies
Journal of Audiology & Otology 2024;28(2):88-92
Sensorineural hearing loss (SNHL) is the most common sensory disorder, with a high Mendelian genetic contribution. Considering the genotypic and phenotypic heterogeneity of SNHL, the advent of next-generation sequencing technologies has revolutionized knowledge on its genomic architecture. Nonetheless, the conventional application of panel and exome sequencing in real-world practice is being challenged by the emerging need to explore the diagnostic capability of whole-genome sequencing, which enables the detection of both noncoding and structural variations. Small molecules and gene therapies represent good examples of how breakthroughs in genetic understanding can be translated into targeted therapies for SNHL. For example, targeted small molecules have been used to ameliorate autoinflammatory hearing loss caused by gain-of-function variants of NLRP3 and inner ear proteinopathy with OSBPL2 variants underlying dysfunctional autophagy. Strikingly, the successful outcomes of the first-in-human trial of OTOF gene therapy highlighted its potential in the treatment of various forms of genetic hearing loss. clustered regularly interspaced short palindromic repeats (CRISPR)-based technologies are currently being developed for site-specific genome editing to treat human genetic disorders. These advancements have led to an era of genotype- and mechanism-based precision medicine in SNHL practice.

PURPOSE: While sleeping problems increase with advancing age, there are inherent differences in sleep between males and females. Previous studies have shown inconsistent results of the relationship between sleep duration and risk of injury from falling. While controlling various sociodemographic and health-related factors, national representative data were used in order to analyze the association between sleep duration and injury from falling among older adults. MATERIALS AND METHODS: The data were obtained from the Korean Community Health Survey of 2011. A total of 55654 individuals aged 65 years and older participated in the study. Multivariable logistic regression analysis was conducted to identify the factors associated with injury from falling. RESULTS: After adjusting for covariates, such as age, sex, marital status, whether or not an individual is a recipient of benefits from the National Basic Livelihood Act, hypertension, diabetes mellitus, dyslipidemia, stress level, and self-rated health status, those who slept five hours or less per day [odds ratio (OR)=1.26; 95% confidence interval (CI)=1.18–1.34; p<0.001] or eight hours or more per day (OR=1.11; 95% CI=1.04–1.17; p=0.001) presented significantly higher ORs for injury from falling. A similar result was found when we conducted stratification by sex. CONCLUSION: The current study supports that there is a relationship between short sleep duration and injury from falling and also identified a marginal risk of long sleep in older adults. Therefore, sleep management in older adults with inadequate sleep duration may be necessary.

OBJECTIVE: To compare the risk of depressive symptoms in adults with physical disabilities between rehabilitation-receivers and non-receivers. METHODS: A total of 3,568 adults with physical disabilities were retrieved from the 2014 Korean National Survey on People with Disabilities database. Four covariate adjustment methods (a multivariable regression model, inverse probability of treatment weighting [IPTW] adjusted for normalized weight, IPTW with stabilized weight, and greedy algorithm with 1:1 propensity score matching) were used to estimate the odds of having depressive symptoms. The dependent variable was depressive symptoms and the independent variable was the use of rehabilitation services. Baseline covariates were 19 demographic variables and 10 chronic condition variables. RESULTS: The four covariate adjustment methods revealed that adults with physical disabilities receiving rehabilitation services had a higher risk of depressive symptoms than those who did not receive these services (adjusted odds ratio, 1.191–1.294). CONCLUSION: Our findings suggest that adults with physical disabilities receiving rehabilitation services have higher risk of developing depressive symptoms. Therefore, rehabilitation professionals need to pay attention to depressive symptoms and establish therapeutic strategies that can reduce such risk in rehabilitation settings.

Asthma is a well-known inflammatory lung disease; however, the specific underlying mechanism is largely unknown. We previously demonstrated that alloferon effectively downregulates pulmonary inflammation. In this study, we examined whether alloferon has a therapeutic effect on asthma. Alloferon remarkably decreased the number of eosinophils, macrophages, and neutrophils in the bronchoalveolar lavage fluid (BALF) from ovalbumin (OVA)-induced asthma mice. It was synergistically decreased with 2.5 mg/kg prednisolone (PDA). Inflammatory cell infiltration around the bronchioles and in the alveolus of OVA-induced asthma mice was effectively prevented by alloferon alone and combined treatment with alloferon and PDS. The production of IL-5 and IL-17 was decreased by alloferon alone and combined treatment with alloferon and PDS. There was no change the level of total immunoglobulin (Ig) following alloferon administration; however, total Ig was decreased by PDS. IgG2a levels were not changed by either alloferon alone or alloferon in combination with PDS. However, the levels of OVA-specific IgG1 and IgE were decreased by alloferon and PDS. In conclusion, our results suggest that a combination of alloferon and prednisolone is effective for the treatment of asthma, as it prevents inflammatory cell infiltration via the down-regulation of IL-5 and IL-17 production and decreases IgG1 and IgE production via the suppression of T helper type 2 immune response.

PURPOSE: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenic anovulation in women of reproductive age. We investigated the metabolic effects of lean and overweight adolescents with PCOS. METHODS: Anthropometric measurements and biochemical parameters were evaluated in 49 adolescents with PCOS and 40 age- and body mass index (BMI)-matched controls. We further divided both PCOS and control groups into those having BMI within the normal range of less than 85th percentile and those being overweight and obese with a BMI greater than 85th percentile. RESULTS: Hemoglobin, gamma-glutamyl transferase (r-GT), total cholesterol, low-density lipoprotein-cholesterol and 2-hour postglucose load plasma insulin levels were significantly elevated in the lean PCOS group than in the lean control group. In the overweight/obese PCOS group, hemoglobin and r-GT levels were significantly elevated than in the overweight/obese control group. In the normal weight group, none of the subjects had metabolic syndrome according to the Adult Treatment Panel III criteria, but the incidence of metabolic syndrome in the overweight/obese PCOS group was 8.3% and that in the overweight/obese control group was 6.7%. CONCLUSION: PCOS in adolescents causes metabolic abnormalities, underscoring the importance of early diagnosis of PCOS in oligomenorrheic adolescents.
