Purpose: Intertrochanteric fractures often involve comminuted fractures, particularly around the intertrochanteric ridge, including the greater and lesser trochanters. In cases with comminuted fractures in the posterior region, maintaining a stable reduction of the anteriormedial region of the fracture surface is essential. Therefore, this study examined the morphologic features of the anterior femur for stable reduction by analyzing the anterior region of intertrochanteric fractures using three-dimensional computed tomography. Materials and Methods: This retrospective study analyzed the imaging data of 51 patients aged 60 years and older who underwent a surgical treatment for intertrochanteric fractures at a single institution from April 2013 to March 2023. The sample contained 15 male patients with an average age of 81.9 years and 36 female patients with an average age of 83.7 years. Forty patients (78.4%) had two or more comorbidities. The bone mineral density was assessed in all cases except for five (9.8%). Results: In 49 cases (96.1%), the anterior fracture line followed the intertrochanteric line and passed through two bony prominences.In two cases (3.9%), the fracture line ran below the intertrochanteric line and involved a large fragment of the lesser trochanter. As the fracture line passed through the inferior medial bony prominence, it exhibited an S-shaped pattern rather than a straight line. The inferior medial bony prominence consisted of cortical bone, with an average thickness of 6.4±1.4 mm, which was significantly thicker than the surrounding average cortical bone thickness (1.5±0.6 mm) but thinner than the cortical bone thickness of the femoral shaft (7.3±1.3 mm).The fracture line in the superior lateral region of the intertrochanteric line included cancellous bone with a cortical bone thickness of 1.1±0.6 mm, which was thin. Conclusion The anterior fracture line followed the femoral intertrochanteric line and curves as it passed through the inferior medial bony prominence. The inferior medial bony prominence, consisting of cortical bone, was significantly thicker than the surrounding average cortical bone.

Digital therapeutics (DTx) are emerging as a transformative innovation in healthcare offering evidence-based digital interventions for the treatment, management, and prevention of various diseases and disorders. In Korea, DTx have gained significant attention as potential solutions to the increasing burden of chronic diseases and mental health conditions. However, the Korean DTx market faces several challenges that hinder its widespread adoption and integration into the national healthcare system. This study provides a comprehensive analysis of the current state of the DTx market in Korea, identifies the key challenges impeding its growth, and proposes strategies for overcoming these obstacles. This study utilized a literature review and market analysis approach to examine the latest research, industry reports, and regulatory documents related to DTx. The analysis focused on three primary areas: (1) the current regulatory landscape, (2) technological advancements and challenges, and (3) economic and commercial factors influencing DTx adoption in Korea. A comparative analysis of global regulatory practices was also conducted to identify best practices. The findings revealed that while Korea has made significant strides in supporting DTx development, the market remains in its early stages. The key challenges include underdeveloped regulatory frameworks, issues with data quality and security, and a lack of established reimbursement pathways. We recommend developing tailored regulatory frameworks for DTx, enhancing policy support for small and medium-sized enterprises involved in DTx development, and increasing investments in technological infrastructure. By addressing these challenges, Korea could position itself as a leader in the global DTx market, delivering innovative and effective treatments to enhance patient care and outcomes.

Background: Fractional exhaled nitric oxide (FeNO) is known to useful biomarker for detecting eosinophilic airway inflammation. However, there is a lack of evidence regarding the role of FeNO in chronic obstructive pulmonary disease (COPD). We aimed to assess whether elevated FeNO and its impact on treatment change into an inhaled corticosteroid (ICS)-containing regimen and association with acute exacerbation (AE) in patients with COPD. Methods: We retrospectively analyzed 107 COPD patients without a history of asthma from March 2016 to December 2019. The patients whose FeNO value was more than 50 parts per billion (ppb) were defined into the high FeNO group. Multivariable analysis with logistic regression was used to identify factors associated with AE in COPD. Results: The median FeNO value was 32 ppb (interquartile range, 19 to 45) and 34 (20.0%) patients were classified as high FeNO group (median 74 ppb). In the high FeNO group, changes in inhaler treatment into an ICS-containing regimen occurred in 23 of 34 patients after the measurement of FeNO. In multivariate analysis, high FeNO was not a contributing factor for AE, but only the high blood eosinophil count (≥300 cells/μL) was associated with AE (adjusted odds ratio, 2.63; 95% confidence interval, 1.01 to 6.91; p=0.049). Conclusion High FeNO value had a significant impact on the prescription of ICSs in COPD patients, but it did not show a significant association with AE either on its own or with changes in treatment.

Purpose: This study investigated the efficacy of intravesical gemcitabine as an alternative to bacillus Calmette–Guérin (BCG) therapy. Materials and Methods: Data were retrospectively collected across seven institutions from February 1999 to May 2023. Inclusion criteria included patients with intermediate- or high-risk non-muscle invasive bladder cancer (NMIBC) who underwent transurethral resection of bladder tumors (TURBT) and received at least four sessions of intravesical gemcitabine or BCG induction therapy. Patient characteristics, complete remission (CR), occurrence, and progression rates were compared. Results: In total, 149 patients were included in this study (gemcitabine, 63; BCG, 86). No differences were apparent between the two groups in baseline characteristics, except for the follow-up period (gemcitabine, 9.2±5.9 months vs. BCG, 43.9±41.4 months, p<0.001). There were no consistent significant differences observed between the two groups in the 3-month (gemcitabine, 98.4% vs. BCG, 95.3%; p=0.848), 6-month (94.9% vs. 90.0%, respectively; p=0.793) and 1-year CR rates (84.2% vs. 83.3%, respectively;p=0.950). Also, there was no significant statistical difference in progression-free survival between the two groups (p=0.953). The occurrence rates of adverse events were similar between the groups (22.2% vs. 22.1%; p=0.989); however, the rate of Clavien– Dindo grade 2 or higher was significantly higher in the BCG group (1.6% vs. 16.3%, respectively; p<0.001). Conclusions Intravesical gemcitabine demonstrated efficacy comparable to BCG therapy for the first year in patients with intermediate- and high-risk NMIBC. However, long-term follow-up studies are warranted.
