BACKGROUND/OBJECTIVES: Perceived diet quality (PDQ) has been suggested as an easy-touse dietary assessment tool. However, its practicality and efficiency are still questionable.This study aimed to gauge the utility of PDQ as an alternative dietary assessment tool among Korean adults by examining PDQ and its associated factors. SUBJECTS/METHODS: An online survey was conducted on 514 Korean adults aged 19 to 64 years in October 2022. PDQ was assessed using a 5-point Likert scale, and participants were categorized into healthy, fair, or unhealthy PDQ groups. The participants were asked about the perceived importance of nutrients and food groups for health and the extent to which they considered these factors in their usual diets using a 5-point Likert scale. A multivariate linear regression model was used to identify the factors associated with PDQ. RESULTS: About 26.7% of participants rated their diets as healthy, while 63.2% rated them as fair and 10.1% rated them as unhealthy. Participants with a healthy PDQ rated perceived importance and consideration of nutrients and food groups higher than the fair or unhealthy PDQ groups. A healthier PDQ was associated with the male gender, an older age, being normal or underweight, having better subjective health, lower use of alcohol, being physically active, having a high interest in healthy diets, and a higher perception of the importance of nutrients and food groups for health. CONCLUSION The PDQ could serve as a simple and rapid screening tool for identifying individuals at risk of poor diets.

Selective cannulation during endoscopic retrograde cholangiopancreatography can be particularly challenging when the papilla is invisible, either due to an intradiverticular papilla (IDP) or because it is covered by a mucosal fold. Endoclipassisted cannulation is an effective and safe technique for everting and fixing the papilla and it can be used alone or in combination with other devices. In this report, we achieved successful papillary cannulation in two cases of IDP and one case where the papilla was covered by a mucosal fold. In two cases, cannulation was accomplished by repositioning the invisible papilla using an endoclip alone, while in one case, we used an endoclip-assisted technique to push a redundant fold with a catheter. Endoclipassisted papillary cannulation can be applied in different situations, either alone or in combination with other devices.

Purpose: This study aimed to compare the short-term outcomes and safety profiles of androgen-deprivation therapy (ADT)+abiraterone/prednisone with those of ADT+docetaxel in patients with de novo metastatic hormone-sensitive prostate cancer (mHSPC). Materials and Methods: A web-based database system was established to collect prospective cohort data for patients with mHSPC in Korea. From May 2019 to November 2022, 928 patients with mHSPC from 15 institutions were enrolled. Among these patients, data from 122 patients who received ADT+abiraterone/prednisone or ADT+docetaxel as the primary systemic treatment for mHSPC were collected. The patients were divided into two groups: ADT+abiraterone/prednisone group (n=102) and ADT+docetaxel group (n=20). We compared the demographic characteristics, medical histories, baseline cancer status, initial laboratory tests, metastatic burden, oncological outcomes for mHSPC, progression after mHSPC treatment, adverse effects, follow-up, and survival data between the two groups. Results: No significant differences in the demographic characteristics, medical histories, metastatic burden, and baseline cancer status were observed between the two groups. The ADT+abiraterone/prednisone group had a lower prostate-specific antigen (PSA) progression rate (7.8% vs. 30.0%; p=0.011) and lower systemic treatment discontinuation rate (22.5% vs. 45.0%; p=0.037). No significant differences in adverse effects, oncological outcomes, and total follow-up period were observed between the two groups. Conclusions ADT+abiraterone/prednisone had lower PSA progression and systemic treatment discontinuation rates than ADT+docetaxel. In conclusion, further studies involving larger, double-blinded randomized trials with extended follow-up periods are necessary.

Purpose: Advanced chronic kidney disease (CKD), including end-stage renal disease (ESRD) on dialysis, increases thromboembolic risk among patients with atrial fibrillation (AF). This study examined the comparative safety and efficacy of direct-acting oral anticoagulant (DOAC) compared to warfarin or no oral anticoagulant (OAC) in AF patients with advanced CKD or ESRD on dialysis. Materials and Methods: Using data from the COmparison study of Drugs for symptom control and complication prEvention of AF (CODE-AF) registry, 260 non-valvular AF patients with advanced CKD (defined as estimated glomerular filtration rate <30 mL/min per 1.73/m2 ) or ESRD on dialysis were enrolled from June 2016 to July 2020. The study population was categorized into DOAC, warfarin, and no OAC groups; and differences in major or clinically relevant non-major (CRNM) bleeding, stroke/systemic embolism (SE), myocardial infarction/critical limb ischemia (CLI), and death were assessed. Results: During a median 24 months of follow-up, major or CRNM bleeding risk was significantly reduced in the DOAC group compared to the warfarin group [hazard ratio (HR) 0.11, 95% confidence interval (CI) 0.01 to 0.93, p=0.043]. In addition, the risk of composite adverse clinical outcomes (major or CRNM bleeding, stroke/SE, myocardial infarction/CLI, and death) was significantly reduced in the DOAC group compared to the no OAC group (HR 0.16, 95% CI 0.03 to 0.91, p=0.039). Conclusion Among AF patients with advanced CKD or ESRD on dialysis, DOAC was associated with a lower risk of major or CRNM bleeding compared to warfarin and a lower risk of composite adverse clinical outcomes compared to no OAC.ClinicalTrials.gov (NCT02786095)

Biliary hamartomas are tumor-like malformations of the liver. Biliary hamartomas are a type of fibrocystic disorder originating from ductal plate malformation and are typically considered benign, but with the risk of malignant transformation. In this case report, we present a rare occurrence of intrahepatic cholangiocarcinoma (ICC) that developed from biliary hamartomas, along with a literature review. A 76-year-old man with a diagnosis of biliary hamartomas had a history of recurrent cholangitis for 12 years, necessitating cholecystectomy, ERCP, and repeated antibiotic treatments. During his last episode, imaging studies revealed a hypervascular infiltrative mass in the right posterior liver segment. A liver biopsy confirmed adenocarcinoma and subsequent surgical pathology revealed ICC originating from biliary hamartomas. Chronic inflammation in the bile duct associated with biliary hamartomas may serve as a potential trigger for malignant transformation, as observed in this case. Therefore, close surveillance is essential for patients with biliary hamartomas presenting with infectious complications.

Background/Aims: We evaluated nailfold capillaroscopy (NFC) of interstitial pneumonia with autoimmune features (IPAF) and compared it with that of patients with connective tissue disease-interstitial lung disease (CTD-ILD) and idiopathic interstitial pneumonia (IIP). Methods: Patients with newly diagnosed as ILD were evaluated using NFC. Baseline demographic, clinical, serological, and high-resolution CT findings were collected. NFC was semi-quantitatively scored with six domains ranging from 0 to 18. In addition, the overall patterns (sclerodermaon-scleroderma patterns) were determined. Results: A total of 81 patients (31 with CTD-ILD, 18 with IPAF, and 32 with IIP) were included. The non-specific interstitial pneumonia pattern was the most common ILD pattern in the CTD-ILD and IPAF groups, whereas the usual interstitial pneumonia pattern was the most common in the IIP group. The semi-quantitative score of the CTD-ILD group was higher than that of the IPAF or IIP groups (5.8 vs 4.2 vs 3.0, p < 0.001, respectively). Giant capillaries and haemorrhages were more frequently present in the CTD-ILD and IPAF groups than in the IIP group. A scleroderma pattern was present in 27.8% of the IPAF group, whereas none of the IIP patients showed a scleroderma pattern. Conclusions NFC findings may be useful in classifying patients with ILD into CTD-ILD/IPAF/IIP.
