Background and Objectives:
The risk profiles, procedural characteristics, and clinical outcomes for women undergoing bifurcation percutaneous coronary intervention (PCI) are not well defined compared to those in men.
Methods:
COronary BIfurcation Stenting III (COBIS III) is a multicenter, real-world registry of 2,648 patients with bifurcation lesions treated with second-generation drug-eluting stents.We compared the angiographic and procedural characteristics and clinical outcomes based on sex. The primary outcome was 5-year target lesion failure (TLF), a composite of cardiac death, myocardial infarction, and target lesion revascularization.
Results:
Women (n=635, 24%) were older, had hypertension and diabetes more often, and had smaller main vessel and side branch reference diameters than men. The pre- and post-PCI angiographic percentage diameter stenoses of the main vessel and side branch were comparable between women and men. There were no differences in procedural characteristics between the sexes. Women and men had a similar risk of TLF (6.3% vs. 7.1%, p=0.63) as well as its individual components and sex was not an independent predictor of TLF. This finding was consistent in the left main and 2 stenting subgroups.
Conclusions
In patients undergoing bifurcation PCI, sex was not an independent predictor of adverse outcome.

Objective:
Many studies have explored sense of self in individuals with autism spectrum disorder (ASD); however, few have reported on their experience of “disembodiment.” This study aimed to investigate the differences in brain activity between patients with ASD and neurotypicals (NTs) under conditions causing disembodiment and to examine the correlation between their interoceptive abilities and disembodiment-related brain activity.
Methods:
18 Participants with ASD and 21 NTs completed psychological evaluations, interoceptive abilities measurement, and functional magnetic resonance imaging (fMRI). The fMRI images were taken while the participants performed tasks involving ball-throwing animations. The task focused on either self-agency related to ball-throwing (Agency Task) or the spatial location of a ball (Location Task). The animations were presented from constantly changing perspective (Changing View) or fixed perspective (Fixed View). The disembodiment-related condition was the interaction between the Agency Task and Changing View.
Results:
Participants with ASD exhibited higher activation than NTs in regions near the left parieto-temporo-occipital junction, left precuneus, left hippocampus, and other brain areas. Furthermore, interoceptive accuracy was negatively correlated with the activity of the left superior parietal and posterior midcingulate areas, whereas interoceptive trait prediction error was positively correlated with the activity of the left hippocampus, mid-temporal area, and left posterior cingulate area in participants with ASD.
Conclusion
These results suggest that disembodiment-related brain activation might be easily manifested by the interaction between perspective-shifting and the experience of agency, and that interoceptive abilities might be related to disembodiment-related brain activation in individuals with ASD.

Background/Aims:
The incidence of steatotic liver disease (SLD) is increasing across all age groups as the incidence of obesity increases worldwide. The existing noninvasive prediction models for SLD require laboratory tests or imaging and perform poorly in the early diagnosis of infrequently screened populations such as young adults and individuals with healthcare disparities. We developed a machine learning-based point-of-care prediction model for SLD that is readily available to the broader population with the aim of facilitating early detection and timely intervention and ultimately reducing the burden of SLD.
Methods:
We retrospectively analyzed the clinical data of 28,506 adults who had routine health check-ups in South Korea from January to December 2022. A total of 229,162 individuals were included in the external validation study. Data were analyzed and predictions were made using a logistic regression model with machine learning algorithms.
Results:
A total of 20,094 individuals were categorized into SLD and non-SLD groups on the basis of the presence of fatty liver disease. We developed three prediction models: SLD model 1, which included age and body mass index (BMI); SLD model 2, which included BMI and body fat per muscle mass; and SLD model 3, which included BMI and visceral fat per muscle mass. In the derivation cohort, the area under the receiver operating characteristic curve (AUROC) was 0.817 for model 1, 0.821 for model 2, and 0.820 for model 3. In the internal validation cohort, 86.9% of individuals were correctly classified by the SLD models. The external validation study revealed an AUROC above 0.84 for all the models.
Conclusions
As our three novel SLD prediction models are cost-effective, noninvasive, and accessible, they could serve as validated clinical tools for mass screening of SLD.

Although histone deacetylase 6 (HDAC6) is considered a therapeutic target for Alzheimer’s disease (AD), its role in cholinergic dysfunction in AD patients remains unclear. This study investigated the effects of (E)-3-(2-(4-fluorostyryl)thiazol-4-yl)-N-hydroxypropanamide (4-FHA), a new synthetic HDAC6 inhibitor, on cognitive and memory impairments in a scopolamine-induced-AD mouse model. Behaviorally, 4-FHA improved scopolamine-induced memory impairments in the Y-maze, passive avoidance, and Morris water maze tests. In addition, 4-FHA ameliorated scopolamine-induced cognitive impairments in the novel object recognition and place recognition tests. Furthermore, 4-FHA increased acetylation of α-tubulin (a major HDAC6 substrate); the expression of BDNF; and the phosphorylation of ERK 1/2, CREB, and ChAT in the hippocampus of scopolamine-treated mice. In summary, according to our data 4-FHA, an HDAC6 inhibitor, improved the cognitive and memory deficits of the AD mouse model by normalizing BDNF signaling and synaptic transmission, suggesting that 4-FHA might be a potential therapeutic candidate for AD.

Journal of Korean Biological Nursing Science 2025;27(2):179-190
Purpose:
This study developed a thermoelectric element (TEE) tourniquet integrating a tourniquet with a temperature control device capable of delivering heat or cold therapy. A randomized controlled trial was conducted to evaluate the effects of the TEE tourniquet on pain, stress, and satisfaction during venipuncture.
Methods:
In total, 118 hospitalized adults were randomly assigned to heat therapy (40~45°C), cold therapy (0~10°C), thermal grill illusion therapy (alternating heat and cold), or the control group. The TEE tourniquet was applied 10 cm above the puncture site. A temperature intervention began 5 seconds before cannulation and was maintained during the procedure, typically lasting 10 to 30 seconds. The control group received the TEE tourniquet without temperature activation. Outcomes included perceived pain and stress (numerical rating scale), observed pain (Wong-Baker FACES), SpO2, stress index, and participant satisfaction.
Results:
Significant differences were found among groups in perceived pain (F = 4.82, p = .003), observed pain (F = 5.50, p = .001), and perceived stress (F = 4.72, p = .004). The heat therapy group reported significantly lower pain and stress than the control group. No significant differences were found in SpO₂, the stress index, or satisfaction.
Conclusion
Heat therapy via the TEE tourniquet significantly reduced venipuncture-related pain and stress. Given its short application time and usability, this device may serve as a clinically useful nursing intervention to improve comfort during invasive procedures.

Purpose:
This study evaluated the postoperative quality of life (QoL) after various types of gastrectomy for gastric cancer.
Materials and Methods:
A multicenter prospective observational study was conducted in Korea using the Korean Quality of Life in Stomach Cancer Patients Study (KOQUSS)-40, a new QoL assessment tool focusing on postgastrectomy syndrome. Overall, 496 patients with gastric cancer were enrolled, and QoL was assessed at 5 time points: preoperatively and at 1, 3, 6, and 12 months after surgery.
Results:
Distal gastrectomy (DG) and pylorus-preserving gastrectomy (PPG) showed significantly better outcomes than total gastrectomy (TG) and proximal gastrectomy (PG) with regard to total score, indigestion, and dysphagia. DG, PPG, and TG also showed significantly better outcomes than PG in terms of dumping syndrome and worry about cancer. Postoperative QoL did not differ significantly according to anastomosis type in DG, except for Billroth I anastomosis, which achieved better bowel habit change scores than the others. No domains differed significantly when comparing double tract reconstruction and esophagogastrostomy after PG. The total QoL score correlated significantly with postoperative body weight loss (more than 10%) and extent of resection (P<0.05 for both).Reflux as assessed by KOQUSS-40 did not correlate significantly with reflux observed on gastroscopy 1 year postoperatively (P=0.064).
Conclusions
Our prospective observation using KOQUSS-40 revealed that DG and PPG lead to better QoL than TG and PG. Further study is needed to compare postoperative QoL according to anastomosis type in DG and PG.
