Purpose: This study compared the differences in health and dietary characteristics according to the subjective health perception among postmenopausal middle-aged women. Methods: Data from the 8 th Korea National Health and Nutrition Examination Survey (2019–2021) were utilized. The participants were naturally postmenopausal women aged 45–59 years, categorized into three groups (good, moderate, and bad) based on their subjective health perception. The general and biochemical characteristics, prevalence of diseases, mental health indicators, dietary behavior factors, food groups, and nutrient intake were compared according to subjective health perception. Results: Bad subjective health perception was associated with lower education levels, not engaging in economic activity, and higher rates of alcohol drinking and smoking. Women with bad subjective health perception had higher fasting blood glucose levels, hemoglobin A1c levels, blood insulin concentrations, and triglyceride concentrations, as well as lower total cholesterol and high-density lipoprotein cholesterol concentrations. In addition, the prevalence of hyperlipidemia and anemia was higher in this group. Women with bad subjective health perceptions were more likely to perceive themselves as fat or thin, experience activity restrictions, perceive stress, have suicidal ideation, and have sought medical assistance for mental issues. They also had higher rates of skipping lunch, lower frequency of fruit consumption, engaging in dietary therapy, feeling chewing discomfort, and higher total daily energy intake. Conclusion These findings suggest that bad subjective health perception in postmenopausal middle-aged women is associated with a higher prevalence of diseases, worse mental health status, and less healthy dietary behaviors. These results can serve as foundational data for future guidelines on desirable health and dietary behaviors aimed at improving the subjective health perceptions of middle-aged women after menopause.

Objective: : Isoflurane, a widely used common inhalational anesthetic agent, can induce brain toxicity. The challenge lies in protecting neurologically compromised patients from neurotoxic anesthetics. Choline alfoscerate (L-α-Glycerophosphorylcholine, α-GPC) is recognized for its neuroprotective properties against oxidative stress and inflammation, but its optimal therapeutic window and indications are still under investigation. This study explores the impact of α-GPC on human astrocytes, the most abundant cells in the brain that protect against oxidative stress, under isoflurane exposure. Methods: : This study was designed to examine changes in factors related to isoflurane-induced toxicity following α-GPC administration. Primary human astrocytes were pretreated with varying doses of α-GPC (ranging from 0.1 to 10.0 μM) for 24 hours prior to 2.5% isoflurane exposure. In vitro analysis of cell morphology, water-soluble tetrazolium salt-1 assay, quantitative real-time polymerase chain reaction, proteome profiler array, and transcriptome sequencing were conducted. Results: : A significant morphological damage to human astrocytes was observed in the group that had been pretreated with 10.0 mM of α-GPC and exposed to 2.5% isoflurane. A decrease in cell viability was identified in the group pretreated with 10.0 μM of α-GPC and exposed to 2.5% isoflurane compared to the group exposed only to 2.5% isoflurane. Quantitative real-time polymerase chain reaction revealed that mRNA expression of heme-oxygenase 1 and hypoxia-inducible factor-1α, which were reduced by isoflurane, was further suppressed by 10.0 μM α-GPC pretreatment. The proteome profiler array demonstrated that α-GPC pretreatment influenced a variety of factors associated with apoptosis induced by oxidative stress. Additionally, transcriptome sequencing identified pathways significantly related to changes in isoflurane-induced toxicity caused by α-GPC pretreatment. Conclusion : The findings suggest that α-GPC pretreatment could potentially enhance the vulnerability of primary human astrocytes to isoflurane-induced toxicity by diminishing the expression of antioxidant factors, potentially leading to amplified cell damage.

Objective: Suicidal ideation (SI) precedes actual suicidal event. Thus, it is important for the prevention of suicide to screen the individualswith SI. This study aimed to identify the factors associated with SI and to build prediction models in Korean adults using machinelearning methods. Methods: The 2010–2013 dataset of the Korea National Health and Nutritional Examination Survey was used as the training dataset(n=16,437), and the subset collected in 2015 was used as the testing dataset (n=3,788). Various machine learning algorithms were appliedand compared to the conventional logistic regression (LR)-based model. Results: Common risk factors for SI included stress awareness, experience of continuous depressive mood, EQ-5D score, depressivedisorder, household income, educational status, alcohol abuse, and unmet medical service needs. The prediction performances of themachine learning models, as measured by the area under receiver-operating curve, ranged from 0.794 to 0.877, some of which were betterthan that of the conventional LR model (0.867). The Bayesian network, LogitBoost with LR, and ANN models outperformed the conventionalLR model. Conclusion A machine learning-based approach could provide better SI prediction performance compared to a conventional LRbasedmodel. These may help primary care physicians to identify patients at risk of SI and will facilitate the early prevention of suicide.Psychiatry Investig 2020;17(4):331-340

Thermal ablation using radiofrequency is a new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent thyroid cancers. The Task Force Committee of the Korean Society of Thyroid Radiology (KSThR) developed recommendations for the optimal use of radiofrequency ablation for thyroid tumors in 2012. As new meaningful evidences have accumulated, KSThR decided to revise the guidelines. The revised guideline is based on a comprehensive analysis of the current literature and expert consensus.

This study assessed the ability of the Sequential Organ Failure Assessment (SOFA) and Acute Physiology, Chronic Health Evaluation (APACHE) II scoring systems, as well as the Simplified Acute Physiology Score (SAPS) II method to predict group mortality in intensive care unit (ICU) patients who were poisoned with organophosphate. The medical records of 149 organophosphate poisoned patients admitted to the ICU from September 2006 to December 2012 were retrospectively examined. The SOFA, APACHE II, and SAPS II were calculated based on initial laboratory data in the Emergency Department, and during the first 24 hr of ICU admission. The probability of death was calculated for each patient based on the SOFA score, APACHE II score, and SAPS II equations. The ability to predict group mortality by the SOFA score, APACHE II score, and SAPS II method was assessed using two by two decision matrices and receiver operating characteristic (ROC) curve analysis. A total of 131 patients (mean age, 61 yr) were enrolled. The sensitivities, specificities, and accuracies were 86.2%, 82.4%, and 83.2% for the SOFA score, respectively; 65.5%, 68.6%, and 67.9% for the APACHE II scoring system, respectively; and 86.2%, 77.5%, and 79.4% for the SAPS II, respectively. The areas under the curve in the ROC curve analysis for the SOFA score, APACHE II scoring system, and SAPS II were 0.896, 0.716, and 0.852, respectively. In conclusion, the SOFA, APACHE II, and SAPS II have different capability to discriminate and estimate early in-hospital mortality of organophosphate poisoned patients. The SOFA score is more useful in predicting mortality, and easier and simpler than the APACHE II and SAPS II.

Ischemic steal syndrome (ISS) is one of the serious complications that can occur after construction of an arteriovenous fistula (AVF) for hemodialysis (HD). Because AVF-related ISS symptoms are usually aggravated during HD sessions, a few cases of ISS in kidney transplantation (KT) recipients have been reported in the literature. We describe a 63-year-old male with diabetic nephropathy who created AVF for maintenance HD and presented with pain at rest and tissue necrosis of the left distal fingers at 10 years post-KT. Brachial angiography revealed the presence of attenuated blood flow through the distal ulnar artery. He underwent finger amputation and AVF ligation, leading to complete relief of ischemic symptoms. The aim of this case report is to help clinicians to diagnosis a steal syndrome in kidney transplantation with a careless AVF for a long period of time.

Relapsing polychondritis is a rare disease which often presents itself firstly in the ear, nose and throat (ENT) department. Characteristic features include auricular chondritis, arthritis, nasal chondritis, ocular inflammation, respiratory tract involvement and audiovestibular damage. The mainstay of treatment has been corticosteroid but other agents have been used either alone or in conjunction with it. These other agents include non-steroidal anti-inflammatory agents, dapsone and colchicine which are helpful for mild disease and cyclophosphamide, azathioprine, cyclosporin. Authors have recently experienced a case of relapsing polychondritis in a 32 year old man who had suddenly experienced loss of hearing in his left ear with vertigo. The patient showed no significant improvement with the treatment using steroid and immunosuppressive agents, but showed significant hearing improvement when he was aggressively treated with plasmapheresis. We report this case with a review of the literature.

PURPOSE: The purpose of this study is to analyze the epidemiologic characteristics of sudden unexpected death in infancy and to evaluate the importance of postmortem autopsy. METHODS: We reviewed, retrospectively, medical records of 34 infants admitted to Kangnam General Hospital from January 1987 to December 2001 because of sudden unexpected death. We investigated the cause of death through medical history, death scene examination, autopsy findings, acylcarnitine and organic acid analysis. RESULTS: Among the total 34 infants, 18 were male(52.9%) and 16 were female(47.1%). Thirty infants(88%) were below the six months of age. Winter was the most affected season(38.2%). Eighteen infants(52.9%) died between 6 and 12AM. The prone sleeping position was observed more frequently than the supine position at death; nine cases in the prone position, six cases in the supine position. The cause of death of 23 cases could not be found by only history and death scene examination. Autopsy was done in 13 cases. Seven cases of them were thought to be SIDS. In six cases, we explained the cause of death with autosy findings. They were an endocardial fibroelastosis, a nesidioblastosis, a subdural hematoma, a bronchopneumonia and two fatty changes of liver. Metabolic screening tests performed in three cases to rule out metabolic disorder since 2000 were all normal. CONCLUSION: We concluded that autopsy and metabolic screening test should be performed to find out the cause of death in sudden unexpected death in infancy.
