Objectives: This study identified changes in social communication and interaction among children with autism spectrum disorder (ASD) through Theraplay. Methods: This study included 20 children who were diagnosed with ASD by a child and adolescent psychiatrist and were recommended to undergo Theraplay in 2012–2017. The Marschak interaction method was used to identify and analyze the interactions between parents and their children. The Korean version of the Social Communication Questionnaire (K-SCQ) was used to evaluate symptoms of ASD. The Wilcoxon signed-rank test was used to compare the differences before and after Theraplay. Results: Upon comparing the differences in total K-SCQ scores, there were statistically significant changes (z=-3.269, p=0.001) in children with ASD. Changes were also confirmed in each category, namely social interaction, communication, and limited and repetitive behavior patterns (p=0.011, p=0.025, p=0.039, respectively). Conclusion This study found that Theraplay may cause significant changes in social communication in children with ASD. Further studies are needed to establish the effectiveness of Theraplay in children with ASD.

This study aimed to estimate the medical cost of cancer in the first five years of diagnosis and in the final six months before death in people who developed cancer after human immunodeficiency virus (HIV) infection in Korea. The study utilized the Korea National Health Insurance Service-National Health Information Database (NHIS-NHID). Among 16,671 patients diagnosed with HIV infection from 2004 to 2020 in Korea, we identified 757 patients newly diagnosed with cancer after HIV diagnosis. The medical costs for 60 months after diagnosis and the last six months before death were calculated from 2006 to 2020. The mean annual medical cost due to cancer in HIV-infected people with cancer was higher for acquired immunodeficiency syndrome (AIDS)-defining cancers (48,242 USD) than for non-AIDS-defining cancers (24,338 USD), particularly non-Hodgkin’s lymphoma (53,007 USD), for the first year of cancer diagnosis. Approximately 25% of the cost for the first year was disbursed during the first month of cancer diagnosis. From the second year, the mean annual medical cost due to cancer was significantly reduced. The total medical cost was higher for non-AIDS-defining cancers, reflecting their higher incidence rates despite lower mean medical costs. The mean monthly total medical cost per HIV-infected person who died after cancer diagnosis increased closer to the time of death. The estimated burden of medical costs in patients with HIV in the present study may be an important index for defining healthcare policies in HIV patients in whom the cancer-related burden is expected to increase.

BACKGROUND: Physical activity is an important factor for preventing osteoporosis. This study aimed to investigate the association of work- and leisure-time physical activities with osteoporosis in postmenopausal women.METHODS: Data were obtained from the Korea National Health and Nutritional Examination Survey 2015–2016. A total of 2,885 postmenopausal women were included in the analysis. The subjects were divided into 3 groups according to the intensity of the work- and leisure-time physical activities. T-test, chi-square test, and multivariable logistic regression analysis were used.RESULTS: No association was found between work-time physical activity and osteoporosis prevalence. However, a dose-response relationship was found in case of leisure-time physical activity. People with leisure-time physical activity of at least >1,000 MET-min/week showed lower prevalence of osteoporosis.CONCLUSION: An appropriate level of leisure-time physical activity should be recommended to prevent and treat osteoporosis.

PURPOSE: High-quality hospice and palliative medicine curricula are necessary in Korean medical schools. This study evaluated changes in students' knowledge and attitudes toward both hospice and palliative care following the completion of a course on these topics, as well as the course's overall role in the basic medical education curriculum.METHODS: Questionnaires measuring knowledge and attitudes were collected before and after the course from 76 fourth-year medical students, who had received instructions integrating both hospice and palliative care in 2016.RESULTS: The questionnaire item “Select the correct answer on the use of opioid pain control in hospice and palliative care” changed the most in terms of number of correct answers pre- and post-course (3.50 and 5.32, respectively; P<0.001). Pre- and post-course, the numbers of students who answered “Strongly Agree” and “Agree” to questions concerning their attitudes toward hospice and palliative care (“I know the purposes and roles of hospice and palliative care”) were 17 (22.4%) and 65 (85.6%), respectively (P≤0.001). Affirmative responses also increased for “As a pre-physician, I know when to describe and advise hospice and palliative care to patients”, from 22 (28.9%) to 65 (85.6%; P≤0.001).CONCLUSION: This study showed that comprehensive hospice education in the form of an integrated educational course might promote changes in medical students' knowledge and attitudes toward hospice and palliative medicine.

Objectives: Prenatal cadmium (Cd) exposure may be associated with attention-deficit/hyperactivity disorder (ADHD) in children. Therefore, the objective of this study was to examine the relationship between Cd exposure during gestation and ADHD at 6 years of age. Methods: As part of an ongoing cohort study (the Environment and Development of Children study), 479 mother-child pairs from Seoul, Korea were included for analysis between 2008 and 2011. The whole blood concentration of Cd was analyzed using atomic absorption spectrophotometry. The parents were surveyed about ADHD behaviors in their children at age 6. Multivariable linear regression models were used to investigate the relationship between prenatal exposure to Cd and ADHD at 6 years of age. Results: Increased prenatal Cd concentrations were associated with increased scores for ADHD for girls, but not for boys, at age 6. A 2-fold increase in the prenatal Cd level was significantly associated with a 22.3% (95% confidence interval, 11.6 to 34.1) increase in ADHD in girls at 6 years of age, as indicated by the linear regression model. Conclusions Our results identified significant associations between prenatal Cd exposure and ADHD scores in 6-year-old girls.

Objectives: Bisphenol A (BPA) is used in the electrical, mechanical, medical, and food industries. Previous studies have suggested that BPA is an endocrine disruptor. Regulation of BPA has led to increased use of bisphenol F (BPF) and bisphenol S (BPS). However, few studies have investigated the associations of BPF and BPS with thyroid dysfunction in children. Our study investigated the associations of prenatal BPA and early childhood BPA, BPF, and BPS exposure with thyroid function in 6-year-old children. Methods: Prenatal BPA concentrations were measured during the second trimester of pregnancy in an established prospective birth cohort. We measured urinary BPA, BPF, and BPS concentrations and thyroid hormone levels (thyroid-stimulating hormone, total T3, and free T4) in 6-year-old children (n=574). We examined the associations between urinary bisphenol concentrations and percentage change of thyroid hormone concentrations using multivariate linear regression. We also compared thyroid hormone levels by dividing the cohort according to BPA, BPF, and BPS concentrations. Results: The associations between prenatal BPA and total T3 levels were statistically significant in all models, except for girls when using a crude model. The associations between urinary BPA and BPS concentrations and levels of all thyroid hormones were not statistically significant. However, we observed that lower free T4 levels (-1.94%; 95% confidence interval, -3.82 to -0.03) were associated with higher urinary BPF concentrations in girls only. Conclusions Our findings identified significant associations between prenatal BPA exposure and total T3 levels in all children and between BPF exposure and free T4 levels in girls only.

Peroxisomal D-bifunctional protein (DBP), encoded by the HSD17B4 gene, catalyzes β-oxidation of very long chain fatty acids (VLCFAs). The deficiency of this peroxisomal enzyme leads to the accumulation of VLCFAs, causing multisystemic manifestations including the brain, retina, adrenal gland, hearing, and skeletal system. Herein, we report the first Korean neonatal case of peroxisomal DBP deficiency and the clinical prognosis over 2 years. This patient showed craniofacial dysmorphism, club foot, and seizures with cyanosis one day after birth. Elevated VLCFAs levels were indicative of a peroxisomal disorder.Targeted exome sequencing was performed and two missense mutations p.Asp117Val and p.Phe279Ser in the HSD17B4 gene were identified. The patient had type III DBP deficiency;therefore, docosahexaenoic acid and non-soluble vitamins were administered. However, progressive nystagmus, optic nerve atrophy, and bilateral hearing defects were observed and follow-up brain imaging revealed leukodystrophy and brain atrophy. Multiple anti-epileptic drugs were required to control the seizures. Over two years, the patient achieved normal growth with home ventilation and tube feeding. Hereby, the subject's parents had support during the second pregnancy from the proven molecular information. Moreover, targeted exome sequencing is an effective diagnostic approach, considering genetic heterogeneity of Zellweger spectrum disorders.

PURPOSE: The purpose of this study was to test the effects on stress and depression by developing and implementing an integrated stress management program for inpatients in the psychiatric closed ward. METHODS: The study was a one-group pretest-posttest design. A total of 36 patients in the closed ward participated in this study. Data were collected through self-report questionnaires to measure hospital stress and depression. Data were analyzed by using t-tests and one-way ANOVA with SPSS/WIN 21.0. RESULTS: Integrated stress management program was designed based on Lazarus and Folkman stress-appraisal-coping model. Total of eight 1-hour sessions were delivered for four weeks in the group. There were significant differences in the inpatient stress scores before and after the intervention. However, the integrated stress management program showed some reduction in depression but did not show signifiant differences statistically. CONCLUSION: Our study findings confirm that the use of the integrated stress management program can reduce stress of the patients, that enable them to stabilize their minds at hospitalization. However, further study is needed to confirm the effects on depression. Thus, it would be beneficial to provide psychiatric nursing intervention tailored to psychiatric patients' symptoms, especially for reducing inpatient stress.

Stress can induce a serious epileptic encephalopathy that occurs during early infancy. Recent studies have revealed that prenatal stress exposure is a risk factor for the development of infantile spasms. Our previous work demonstrates that prenatal stress with betamethasone-induced alterations to the expression of the K⁺/Cl⁻ co-transporter (KCC2) in gamma-aminobutyric acid (GABA) interneurons lowers the seizure threshold in exposed animals. Here, we further investigated the mechanisms involved in this KCC2 dysfunction and explored possible treatment options. We stressed Sprague-Dawley rats prenatally and further treated dams with betamethasone on gestational day 15, which increases seizure susceptibility and NMDA (N-Methyl-D-aspartate)-triggered spasms on postnatal day 15. In this animal model, first, we evaluated baseline calpain activity. Second, we examined the cleavage and dephosphorylation of KCC2. Finally, we checked the effect of a calpain inhibitor on seizure occurrence. The phosphorylated-N-methyl-D-aspartate Receptor 2B (NR2B):non-phosphorylated NR2B ratio was found to be higher in the cortex of the prenatally stressed beta-methasone model. We further found that the betamethasone model exhibited increased phosphorylation of calpain-2 and decreased phosphorylation of KCC2 and Glutamic acid decarboxylase 67 (GAD67). After using a calpain inhibitor in prenatal-stress rats, the seizure frequency decreased, while latency increased. GABAergic depolarization was further normalized in prenatal-stress rats treated with the calpain inhibitor. Our study suggests that calpain-dependent cleavage and dephosphorylation of KCC2 decreased the seizure threshold of rats under prenatal stress. Calpain-2 functions might, thus, be targeted in the future for the development of treatments for epileptic spasms.
