Background: This study investigated the association between thyroid function and the 10-year cardiovascular disease (CVD) risk in patients with diabetes. Methods: This retrospective cross-sectional study analyzed 246 patients with diabetes aged 30 to 79 years (weighted n=1,611,708) from the 2013 to 2014 Korea National Health and Nutrition Examination Survey. Individuals with a history of CVD, thyroid disease, or pregnancy were excluded. Thyroid function was categorized as euthyroid, hypothyroid, or hyperthyroid, based on serum thyroid-stimulating hormone (TSH) levels (reference in Koreans, 0.62–6.86 mIU/L). The 10-year CVD risk was estimated using the Predicting Risk of CVD EVENTs calculator. Results: The mean participant age was 54.3±10.1 years, with a male-to-female ratio of 1.41:1. Although patients with hypothyroid (14.1%) and hyperthyroid (15.7%) statuses showed a higher CVD risk than those with euthyroid status (12.3%), the difference was not statistically significant (p=0.337). However, in the hypothyroid group (n=11), TSH levels showed a moderate correlation with 10-year CVD risk (r=0.603, p<0.05), although this finding should be interpreted with caution owing to the small sample size. After adjusting for diabetes- and thyroid-related variables, TSH level was independently associated with higher estimated 10-year CVD risk, particularly in patients with a glycated hemoglobin level of <7% (adjusted coefficient, 0.17; 95% confidence interval, 0.05–0.29; p<0.05). Conclusion Monitoring TSH levels in patients with well-controlled diabetes may provide additional information regarding the risk of CVD; however, prospective studies are needed to confirm the long-term prognostic value.

Purpose: This study aimed to assess the rate of germline variant detection following targeted cascade genetic testing among family members of prostate cancer (PCa) probands. Materials and Methods: Records of PCa patients with confirmed germline mutations and their family members recommended for cascade testing were retrospectively reviewed. Cascade testing for germline mutations identified in PCa probands was conducted among first-degree relatives (FDRs) and second-degree relatives. The rate of counseled family members who proceeded to actual testing, the proportion of mutation carriers detected, and the reasons for test refusal were analyzed. Clinical variables, including family history of malignancy and variant type, were also collected. Results: A total of 15 PCa patients and 44 eligible relatives were included in the final analysis. Eleven probands (73.3%) had a positive family history of cancer across 22 family members (18 FDRs). Among FDRs, breast/ovarian cancer (27.8%) and gastric cancer (22.2%) were the most common, followed by lymphoma, prostate, esophageal, and lung cancer (each 11.1%). Among probands, BRCA2 variants were predominant (80%, 12 of 15), followed by BRCA1 (n=2) and MLH1 (n=1) mutations. Of 41 eligible FDRs, 21 (51.2%) underwent genetic testing, and 61.9% (13 of 21) were found to carry identical germline mutations. Approximately half of the counseled family members declined testing due to concerns regarding privacy and disclosure, travel distance to the clinic, or loss to follow-up. Conclusion Over half of the FDRs who underwent cascade testing were confirmed to carry pathogenic germline variants. As the first study to evaluate cascade testing in family members of PCa probands in Korea, these findings underscore the strong heritable component of PCa and highlight the need to enhance participation in familial genetic screening.

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.

Purpose: This study aimed to evaluate the feasibility of measuring liver fat using the volumetric measurement method (Fatvol) by comparing it with the conventional 27-regions of interest drawing method (Fatroi). Materials and Methods: This retrospective study included 67 patients who underwent liver magnetic resonance imaging with fat quantification in August or September 2020.Two experienced abdominal radiologists measured the proton density fat fraction (PDFF) of the liver using the mDIXON-Quant sequence for each of two methods. The PDFF was measured twice with each method at intervals of at least 4 weeks to avoid recall bias. Measurement times were recorded. The intra-class correlation coefficient (ICC) was calculated for intra-exam repeatability, inter-reviewer reproducibility, and inter-exam agreement. Results: Measurement times for Fatvol were significantly shorter than for Fatroi. Measurement times for Fatroi and Fatvol, respectively, for reviewer A were 209.4 ± 55.1 s and 137.2 ± 51.5 s in session 1, and 180.9 ± 37.3 s and 127.0 ± 46.1 s in session 2. For reviewer B, the times were 190.7 ± 30.1 s and 74.8 ± 27.4 s in session 1, and 174.6 ± 21.8 s and 64.1 ± 17.5 s in session 2. In all cases, p < 0.001. The mean PDFF values were 7.2% ± 6.4% and 7.2% ± 6.5% (sessions 1 and 2, respectively) for Fatroi and 7.4% ± 6.0% and 7.3% ± 6.1% for Fatvol for reviewer A. For reviewer B, they were 7.1% ± 6.6% and 7.1% ± 6.6% for Fatroi and 7.4% ± 5.8% and 7.4% ± 5.8% for Fatvol. The ICCs between measurement methods (0.998 and 0.995 for reviewers A and B, respectively), for Fatvol within each reviewer (0.999 and 1.000 in sessions 1 and 2, respectively), and between reviewers (0.999) were excellent. Conclusion The measurement time could be significantly reduced using Fatvol compared to Fatroi while maintaining the consistency of the liver fat measurement values.

Purpose: This study aimed to investigate the impact of BRCA1/2 mutational status on survival outcomes in patients with platinum-sensitive relapsed (PSR) epithelial ovarian cancer (EOC). Materials and Methods: We retrospectively identified patients who received secondary treatment for PSR EOC at our institution between January 2007 and June 2021 and who underwent BRCA1/2 gene testing by either germline or somatic methods. The association between BRCA1/2 mutational status and survival outcomes was evaluated. Both secondary cytoreductive surgery (CRS) and maintenance therapy were stratified considering real-world clinical practice. Results: Of 262 patients, 91 (34.7%) and 171 (65.3%) were assigned to BRCA1/2 mutation and wild-type groups, respectively. The two groups had similar proportions of patients undergoing secondary CRS (26.4% vs. 32.7%, p=0.286) and maintenance therapy (54.9% vs. 46.2%, p=0.178). Overall, no differences in progression-free survival (PFS; median, 19.7 vs. 15.1 months, p=0.120) and overall survival (OS; p=0.400) were observed between the two groups. In multivariate analyses, BRCA1/2 mutational status was not associated with PFS (adjusted hazard ratio, 0.816; 95% confidence interval, 0.596 to 1.119; p=0.207). BRCA1/2 mutational status did not affect PFS among patients who underwent secondary CRS (n=80) and among those who did not (n=182) (p=0.074 and p=0.222, respectively). PFS did not differ in the BRCA1/2 mutational status among the patients who received bevacizumab maintenance (n=90, p=0.992). Conclusion In this real-world evidence study, BRCA1/2 mutational status itself was not associated with PFS and OS in PSR EOC, which was consistent with whether secondary CRS or not and with bevacizumab maintenance.

Background/Aims: Intrahepatic cholangiocarcinoma (iCCA) is a subgroup of cholangiocarcinoma and is the second- most-common primary hepatic tumor. Several predictive and prognostic factors have been analyzed; however, in this study we focused on the influence of age. Our aim was to use real-world results to determine the influence of age in iCCA patients. Methods: A retrospective analysis of patients treated between 2005 and 2016 at Konkuk University Medical Center. In total, 133 patients with iCCA were identified. The mass-forming, periductal-infiltrating, and intraductal-growth types were included; patients with extrahepatic or hilar-type cholangiocarcinoma were excluded. We defined two groups: a younger group, age < 65 years, and an older group, age ≥ 65 years. Statistical analyses using univariate and multivariate Cox regression analyses, including the Kaplan-Meier method, were conducted. Results: In total, 114 patients were enrolled. The two groups differed with regard to treatment options such as surgery with adjuvant chemotherapy or palliative chemotherapy (p = 0.012, p < 0.001). The younger group had significantly longer survival than the older group (p = 0.017). In the younger group, patients who received therapy had longer survival than those who did not (hazard ratio, 3.942; 95% confidence interval, 2.053 to 7.569; p < 0.001). Multivariate analysis indicated that younger age, lower bilirubin, low CA 19-9, and no lymph-node involvement were independent factors for improved survival. Conclusions Younger patients and those who underwent surgery with adjuvant chemotherapy had longer survival. The younger the patient, the more treatments received, including palliative chemotherapy.

Background: Using KIDS-KAERS database (KIDS-KD) from 2016 to 2020, the aim is to investigate signals of adverse events of alpha-adrenoceptor antagonists and to present adverse events that are not included in the precautions for use when marketing approval. Methods: This study was conducted by disproportionality analysis. Data mining analysis was performed to detect signals of alpha-adrenoceptor antagonists, such as terazosin, doxazosin, alfuzosin, silodosin, and tamsulosin. The signal was defined by three criteria as proportional reporting ratio (PRR), reporting odds ratio (ROR), and information component (IC). Detected signals were compared with product labeling and the European Medicines Agency-Important Medical Events list. Results: Out of the total number of 408,077 reports for adverse events, 6,750 cases were reported as adverse events of alpha-adrenoceptor antagonists. Dizziness, mouth dryness, hypotension postural, and oedema peripheral are identified as common adverse events of five alphaadrenoceptor antagonists and are typically listed on drug labels. However, new signals were detected for pneumonia, chronic obstructive airway disease, eye diseases such as glaucoma and cataracts, fracture, and ileus of tamsulosin that were not previously listed on the drug labels in Korea. Conclusions This study identified signals related to adverse drug reactions of alpha-adrenoceptor antagonists and presented serious adverse events, suggesting new adverse reactions to be aware of when using alpha-adrenoceptor antagonists.
