The Korean Journal of Internal Medicine 2024;39(5):801-812
Background/Aims:
Immune checkpoint inhibitors (ICIs) can induce immune-related adverse events, including endocrine dysfunctions, which can have serious consequences on patient health and quality of life. The clinical course and characteristics of immune-related hypophysitis (irH) are not well established. This study aimed to analyze the clinical course and characteristics of irH.
Methods:
This single-center, retrospective study analyzed data from electronic medical records of Asan Medical Center, spanning January 2017 through June 2021. It included adult patients with solid tumors who underwent thyroid and adrenal function tests, along with gonadotropin and/or growth hormone evaluations, following the initiation of ICI treatment within the same period. The study explored the clinical characteristics of ICI-treated patients with and without irH, the incidence of irH, the time to irH onset, and the associated hormonal changes.
Results:
Twenty-one patients were included in this analysis. Clinical characteristics did not differ significantly between the irH (n = 13) and non-irH (n = 8) groups. Deficiency rates in the irH group were 23.1% for thyroid-stimulating hormone (n = 3), 76.9% for adrenocorticotropic hormone (n = 10), 61.5% for gonadotropin (n = 8), and 15.4% for growth hormone (n = 2). The overall incidence was 0.9 per person-year, with 6-month and 1-year cumulative incidences of 38.8% and 57.1%, respectively. The median time from ICI initiation to irH diagnosis was 7.7 months. Time to levothyroxine replacement was shorter in the irH group.
Conclusions
The findings provide evidence that could facilitate the prediction of ICI-induced irH based on clinical course and characteristics.

BACKGROUND:
Parkinson’s disease (PD) is one of the most prevalent neurodegenerative diseases, following Alzheimer’s disease. The onset of PD is characterized by the loss of dopaminergic neurons in the substantia nigra. Stem cell therapy has great potential for the treatment of neurodegenerative diseases, and human nasal turbinate-derived stem cells (hNTSCs) have been found to share some characteristics with mesenchymal stem cells. Although the Hippo signaling pathway was originally thought to regulate cell size in organs, recent studies have shown that it can also control inflammation in neural cells.
METHODS:
Dopaminergic neuron-like cells were differentiated from SH-SY5Y cells (DA-Like cells) and treated with 1-Methyl-4-phenylpyridinium iodide to stimulate Reactive oxidative species (ROS) production. A transwell assay was conducted to validate the effect of hNTSCs on the Hippo pathway. We generated an MPTP-induced PD mouse model and transplanted hNTSCs into the substantia nigra of PD mice via stereotaxic surgery. After five weeks of behavioral testing, the brain samples were validated by immunoblotting and immunostaining to confirm the niche control of hNTSCs.
RESULTS:
In-vitro experiments showed that hNTSCs significantly increased cell survival and exerted anti-inflammatory effects by controlling ROS-mediated ER stress and hippocampal signaling pathway factors. Similarly, the in-vivo experiments demonstrated an increase in anti-inflammatory effects and cell survival rate. After transplantation of hNTSCs, the PD mouse model showed improved mobility and relief from PD symptoms.
CONCLUSION
hNTSCs improved the survival rate of dopaminergic neurons by manipulating the hippocampal pathway through Yes-associated protein (YAP)/transcriptional coactivator with a PDZ-binding motif (TAZ) by reducing inflammatory cytokines. In this study, we found that controlling the niche of hNTSCs had a therapeutic effect on PD lesions.

Purpose:
Early intervention after trauma is needed for reduction in clinical distress and prevention of chronic posttraumatic stress disorder (PTSD). This study describes findings from an open pilot trial of a brief stabilization psychotherapy based on imagery techniques for adults with acute PTSD (i.e., within 3 months of onset).
Materials and Methods:
Four sessions of 60-minute individual psychotherapy were conducted on 18 participants with PTSD within 3 months after accidents, 15 of whom completed the treatment. The clinician-administered PTSD scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), the Hamilton Depression and Anxiety Rating Scales, and self-questionnaires were administered at pre-treatment, post-treatment, and 6-month follow-up.
Results:
Eight (53.3%) of the 15 patients at post-treatment and 8 of the 9 patients at 6-month follow-up did not meet the DSM-5 criteria for PTSD. Reliable change of PTSD symptoms after treatment was observed in 6 of 15 (45.0%) patients at post-treatment and in 4 of 9 (45.0%) patients after 6 months. There was a significant decrease in PTSD, depression, anxiety, and impaired quality of life scores after treatment, and these gains were maintained after 6 months. No cases of exacerbated PTSD symptoms were observed among completers and non-completers.
Conclusion
Our findings suggest that brief stabilization sessions are safe treatment options for acute PTSD (KCT0001918).

Background:
Stress management is an important component of management of mental health. Stress processing can be understood as the appraisal of and coping with stress. This study aimed to compare positive and negative perceptions of stress according to patterns of coping strategies.
Methods:
The study recruited 116 college students who completed the Perceived Stress Scale and Coping Inventory for Stressful Situations using a tablet PC or smartphone application. K-means cluster analysis was used to categorize the subjects into three clusters.
Results:
Positive perceptions were highest in Cluster 2 (i.e., task and avoidance dominant) at 3.18±0.66 followed by 2.30±0.65 in Cluster 1 (passive coping) and lowest in Cluster 3 (emotion dominant) at 1.75±0.63. Negative perceptions were highest in Cluster 3 at 2.45±0.66 followed by Cluster 1 at 1.66±0.65 and Cluster 2 at 1.07±0.68.
Conclusion
Differences in coping patterns can reduce the negative effects of stress. Thus, assessing the perception and management of stress can be useful and help people change their coping styles to more adaptive ones. Toward this end, a mobile application can be an appropriate tool.

Objective:
To identify the prevalence and factors associated with T-score discordance between the spine and hip, as well as between the paretic and non-paretic hips in hemiplegic stroke patients, this study investigated bone mineral density (BMD) patterns. Bone loss predominantly affects the paretic hip after a stroke, and typical clinical assessments using dual-energy X-ray absorptiometry (DXA) that scan the lumbar spine (LS) and a single hip may overlook an osteoporosis diagnosis. This oversight could potentially lead to suboptimal treatment for stroke patients.
Methods:
This study was a multicenter retrospective analysis of 540 patients admitted for stroke rehabilitation between October 2014 and February 2022, who underwent DXA of LS and bilateral hips.
Results:
The prevalence rates of concordance, low LS discordance, and low hip discordance between the LS and hips were 48.2%, 12.2%, and 39.6%, respectively. The discordance rate between bilateral hips was 17.0%. The paretic side had significantly lower total hip T-scores than the non-paretic side (p<0.001). Notably low paretic hip discordance was more prevalent during the chronic phase. DXA scans of the LS and both hips revealed a 0.7%–0.9% higher major discordance compared to LS and single hip DXA scans. The multivariate analysis revealed a significant correlation between a low paretic hip discordance and cognitive impairment (adjusted odds ratio 0.071, 95% confidence interval 0.931–1.003, p<0.05).
Conclusion
Since stroke survivors are at high risk for hip fractures, comprehensive BMD assessments, which include LS and bilateral hips, should be considered for post-stroke osteoporosis care to enhance diagnostic accuracy and timely treatment.

Journal of Nutrition and Health 2024;57(6):667-684
Purpose:
This study evaluated the nutrition and food intake status among adults in Jeju, Republic of Korea, based on their sociodemographic characteristics and obesity.
Methods:
Nine hundred and forty-nine adults aged 19 years or older were included based on the 2022 Jeju Nutrition and Physical Activity Survey data. A dietary assessment was conducted using a one-day, 24-hour recall method, and the nutrition status was evaluated using the 2020 Dietary Reference Intakes for Koreans. The sociodemographic status included sex, age, education, and household income, and obesity was defined as a body mass index (BMI) of ≥ 25 kg/m 2 .
Results:
The mean age of the subjects was 49.8 years, and the overall prevalence of obesity was 48.4% (59.5% for males and 37.2% for females). The top three insufficient nutrients consumed at less than the estimated average requirement were calcium (77.7%), vitamin A (77.3%), and vitamin C (61.3%), while 40.9% of the subjects consumed fat as more than 30% of their total energy intake. The sodium intake was approximately 1.5 times higher than the chronic disease risk reduction intake level. In terms of food groups, the participants consumed more meat (148.2 g/day), seafood (69.0 g/day), potatoes, and starches (41.6 g/day) but consumed fewer vegetables (214.3 g/day) and less dairy (62.0 g/day) than Korean adults. The nutritional status and food intake patterns differed by the sociodemographic status. In addition, the obese group consumed more poultry and beverages than the non-obese group (p < 0.05 for all).
Conclusion
Adults in Jeju under-consume essential nutrients while over-consuming certain nutrients, such as fat and sodium. The nutritional status also varied according to the sociodemographic characteristics. These findings suggest that sociodemographic factors should be considered carefully when developing nutritional policies and programs to improve the nutritional status and address obesity among adults in Jeju.
