Purpose: The study investigated whether incorporating magnetic resonance imaging (MRI) alongside ultrasonography (US) in the preoperative evaluation is associated with differing survival outcomes between male and female breast cancer patients in a matched analysis. Additionally, clinicopathological prognostic factors were analyzed. Methods: Between January 2005 and December 2020, 93 male and 28,191 female patients who underwent breast surgery were screened. Exact matching analysis was conducted for age, pathologic T and N stages, and molecular subtypes. The clinicopathological characteristics and preoperative imaging methods of the matched cohorts were reviewed. Disease-free survival (DFS) and overall survival (OS) were assessed using Kaplan-Meier analysis, and Cox proportional hazards regression analysis was used to identify prognostic factors. Results: A total of 328 breast cancer patients (61 men and 267 women) were included in the matched analysis. Male patients had worse DFS (10-year DFS, 70.6% vs. 89.2%; P=0.001) and OS (10-year OS, 64.4% vs. 96.3%; P<0.001) than female patients. The pathologic index cancer size (hazard ratio [HR], 2.013; 95% confidence interval [CI], 1.063 to 3.810; P=0.032) was associated with worse DFS, whereas there were no significant factors associated with OS. Adding MRI to US for preoperative evaluation was not associated with DFS (HR, 1.117; 95% CI, 0.223 to 5.583; P=0.893) or OS (HR, 1.529; 95% CI, 0.300 to 7.781; P=0.609) in male patients. Conclusion Adding breast MRI to US in the preoperative evaluation was not associated with survival outcomes in male breast cancer patients, and the pathologic index cancer size was associated with worse DFS.

Since the cortico-cortical evoked potential (CCEP) was first introduced in 2004, CCEP monitoring has been utilized in various types of brain surgery to achieve maximal safe resection (MSR). MSR is the primary goal in improving the prognosis of glioma; however, this is particularly challenging when the tumor is located around eloquent areas. Since the complexity of the language network system makes it more difficult to achieve MSR, language area mapping is essential when tumors are located around these areas. Awake surgery has been the gold standard for intraoperative language area mapping.However, awake craniotomy is not always feasible due to various clinical and patient-related factors.CCEP monitoring has emerged as a promising alternative for intraoperative language function assessment under general anesthesia to overcome the limitations of awake surgery. This review aims to summarize the current evidence on CCEP-guided surgery, focusing on its effectiveness in preserving language function.

This study examined the potential moderating effects of insulin resistance and dietary inflammatory index (DII) on the relationship between body mass index (BMI) and peak postprandial glucose levels in patients with prediabetes and type 2 diabetes. Methods: A retrospective analysis was conducted, using integrated nutritional data from a diabetes management program for patients with prediabetes and type 2 diabetes who used continuous glucose monitoring (CGM). Data from 17 patients, including 408 meal records, were analyzed. The energy-adjusted DII (E-DII) was calculated, and peak postprandial glucose was matched for each meal. Statistical tests analyzed differences and relationships between variables. Hayes' SPSS PROCESS macro version 4.0 was used to identify the moderating effects. Results: Peak postprandial glucose levels varied significantly among E-DII subgroups (p < .026) and were positively correlated with insulin resistance (rho = .30, p = < .001) and E-DII (rho = .14, p = .004). Insulin resistance and E-DII had a multiple additive moderating effect on the relationship between BMI and peak postprandial glucose levels in glucose-controlled patients (F = 12.22, p < .001), explaining 21.6% of the variance. Conclusion: Higher E-DII scores, which indicated a more pro-inflammatory diet, were associated with increased glucose levels, especially for patients who were overweight and mildly obese. Patients with obesity who received insulin therapy had varied postprandial glucose levels depending on their insulin resistance status. These findings highlight the importance of tailored dietary interventions, inflammation management, and CGM to improve obesity-related glucose regulation.

Background: Shortage of organ donors in the Republic of Korea has become a major problem. To address this, it has been questioned whether heart transplant (HTx) allocation should be modified to reduce priority of older patients. We aimed to evaluate post-HTx outcomes according to recipient age and specific pre-HTx conditions using a nationwide prospective cohort. Methods: We analyzed clinical characteristics of 628 patients from the Korean Organ Transplant Registry who received HTx from January 2015 to December 2020. Enrolled recipients were divided into three groups according to age. We also included comorbidities including ambulatory status. Non-ambulatory status was defined as pre-HTx support with either extracorporeal membrane oxygenation, continuous renal replacement therapy, or mechanical ventilation. Results: Of the 628 patients, 195 were < 50 years, 322 were 50–64 years and 111 were ≥ 65years at transplant. Four hundred nine (65.1%) were ambulatory and 219 (34.9%) were nonambulatory. Older recipients tended to have more comorbidities, ischemic cardiomyopathy, and received older donors. Post-HTx survival was significantly lower in older recipients (P = 0.025) and recipients with non-ambulatory status (P < 0.001). However, in contrast to non-ambulatory recipients who showed significant survival differences according to the recipient’s age (P = 0.004), ambulatory recipients showed comparable outcomes (P = 0.465). Conclusion Our results do not support use of age alone as an allocation criterion. Transplant candidate age in combination with some comorbidities such as non-ambulatory status may identify patients at a sufficiently elevated risk at which suitability of HTx should be reconsidered.
