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.

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.

Objective: Fatigue is a common, debilitating nonmotor symptom of Parkinson’s disease (PD), but its mechanism is poorly understood. We aimed to determine whether electroencephalography (EEG) could objectively measure fatigue and to explore the pathophysiology of fatigue in PD. Methods: We studied 32 de novo PD patients who underwent EEG. We compared brain activity between 19 PD patients without fatigue and 13 PD patients with fatigue via EEG power spectra and graphs, including the global efficiency, characteristic path length, clustering coefficient, small-worldness, local efficiency, degree centrality, closeness centrality, and betweenness centrality. Results: No significant differences in absolute or relative power were detected between PD patients without or with fatigue (all p > 0.02, Bonferroni-corrected). According to our network analysis, brain network efficiency differed by frequency band. Generally, the brain network in the frontal area for theta and delta bands showed greater efficiency, and in the temporal area, the alpha1 band was less efficient in PD patients without fatigue (p < 0.0001, p = 0.0011, and p = 0.0007, respectively, Bonferroni-corrected). Conclusion Our study suggests that PD patients with fatigue have less efficient networks in the frontal area than PD patients without fatigue. These findings may explain why fatigue is common in PD, a frontostriatal disorder. Increased efficiency in the temporal area in PD patients with fatigue is assumed to be compensatory. Brain network analysis using graph theory is more valuable than power spectrum analysis in revealing the brain mechanism related to fatigue.

Background and Objectives: The serum galactomannan test (GM test) and the (1,3)-β-D-glucan test (G test) are utilized in diagnosing invasive fungal sinusitis. However, their effectiveness in detecting paranasal sinus fungus balls (FBs) has not been established. This study aimed to explore their diagnostic value in patients with FBs. Methods: We retrospectively reviewed the medical records of 105 patients (42 with FBs and 63 with chronic rhinosinusitis [CRS]) who underwent serum GM and G tests between June 2020 and May 2021. Olfactory test results and demographics were also analyzed. Results: There were 42 FB patients (10 men, 32 women) and 63 CRS patients (27 men, 36 women). The positivity rates for serum GM (7.1% in the FB group vs. 3.2% in the CRS group, p=0.640) and G test (9.5% in the FB group vs. 11.1% in the CRS group, p=0.482) did not differ significantly between groups. The sensitivities of the GM and G tests were 7.1% and 9.5%, respectively, and their specificities were 96.8% and 88.9%, respectively. The positive predictive values were 60.0% for the GM test and 36.3% for the G test, and the negative predictive values were 61.0% for the GM test and 59.6% for the G test. Conclusion Serum GM and G tests demonstrated low sensitivity and high specificity, indicating limited effectiveness in differentiating between patients with FBs and those with CRS. Histological examination remains the gold standard for the definitive diagnosis of FBs.
