		                        			Outcomes of deferring percutaneous coronary intervention (PCI) without invasive physiologic assessment for intermediate coronary lesions is uncertain.We sought to compare long-term outcomes between medical treatment and PCI of intermediate lesions without invasive physiologic assessment. 
		                        		
		                        			Methods:
		                        			A total of 899 patients with intermediate coronary lesions between 50% and 70% diameter-stenosis were randomized to the conservative group (n=449) or the aggressive group (n=450). For intermediate lesions, PCI was performed in the aggressive group, but was deferred in the conservative group. The primary endpoint was major adverse cardiac events (MACE, a composite of all-cause death, myocardial infarction [MI], or ischemia-driven any revascularization) at 3 years. 
		                        		
		                        			Results:
		                        			The number of treated lesions per patient was 0.8±0.9 in the conservative group and 1.7±0.9 in the aggressive group (p=0.001). At 3 years, the conservative group had a significantly higher incidence of MACE than the aggressive group (13.8% vs. 9.3%; hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.00–2.21; p=0.049), mainly driven by revascularization of target intermediate lesion (6.5% vs. 1.1%; HR, 5.69; 95% CI, 2.20–14.73;p<0.001). Between 1 and 3 years after the index procedure, compared to the aggressive group, the conservative group had significantly higher incidence of cardiac death or MI (3.2% vs.0.7%; HR, 4.34; 95% CI, 1.24–15.22; p=0.022) and ischemia-driven any revascularization. 
		                        		
		                        			Conclusions
		                        			For intermediate lesions, medical therapy alone, guided only by angiography, was associated with a higher risk of MACE at 3 years compared with performing PCI, mainly due to increased revascularization.

		                        			 This report presents the case of severe tooth wear and vertical dimension loss in a 71-year-old male patient. A combined conventional and digital approach was employed for full-mouth rehabilitation. After determining an increase in the vertical dimension of 5.5 mm using an anterior jig and diagnostic wax-up, provisional restorations were fabricated and adjusted throughout the adaptation period.For the fabrication of the final prosthesis, digital methodologies such as oral scanning and occlusal acquisition were performed. To obtain precise margin data, a die model was fabricated using the traditional impression method, followed by model scanning, which was then combined with intraoral scan data. The final prosthesis was made of zirconia to enhance esthetics and strength. Consequently, the treatment enhanced both function and esthetics, leading to high patient satisfaction with the outcomes.

		                        			 The shape of the maxillary anterior teeth is an essential factor in esthetics because this region is prominently exposed during conversations and smiles, significantly influencing one’s impression. Moreover, the form and color of the gingiva in the anterior teeth play a vital role in determining esthetics. Therefore, various factors should be considered when improving the esthetics of the maxillary anterior teeth. This report is aimed at introducing the use of digital devices and software to analyze various factors, determining the amount of gingival and alveolar bone resection in a patient with esthetically unpleasing maxillary anterior teeth due to a gummy smile or gingival asymmetry. Furthermore, this study describes the method for creating a digital surgical guide using CAD software for esthetic crown lengthening and reports on the achieved esthetic improvements.

		                        			 Purpose:
		                        			Triple-negative breast cancer (TNBC) is a particularly challenging subtype of breast cancer, with a poorer prognosis compared to other subtypes. Unfortunately, unlike luminal-type cancers, there is no validated biomarker to predict the prognosis of patients with early-stage TNBC. Accurate biomarkers are needed to establish effective therapeutic strategies. 
		                        		
		                        			Materials and Methods:
		                        			In this study, we analyzed gene expression profiles of tumor samples from 184 TNBC patients (training cohort, n=76; validation cohort, n=108) using RNA sequencing. 
		                        		
		                        			Results:
		                        			By combining weighted gene expression, we identified a 10-gene signature (DGKH, GADD45B, KLF7, LYST, NR6A1, PYCARD, ROBO1, SLC22A20P, SLC24A3, and SLC45A4) that stratified patients by risk score with high sensitivity (92.31%), specificity (92.06%), and accuracy (92.11%) for invasive disease-free survival. The 10-gene signature was validated in a separate institution cohort and supported by meta-analysis for biological relevance to well-known driving pathways in TNBC. Furthermore, the 10-gene signature was the only independent factor for invasive disease-free survival in multivariate analysis when compared to other potential biomarkers of TNBC molecular subtypes and T-cell receptor β diversity. 10-gene signature also further categorized patients classified as molecular subtypes according to risk scores. 
		                        		
		                        			Conclusion
		                        			Our novel findings may help address the prognostic challenges in TNBC and the 10-gene signature could serve as a novel biomarker for risk-based patient care.

		                        			 Asthma is an allergic disease characterized by chronic inflammation of the airways, leading to bronchoconstriction and excessive mucus production with symptoms of dyspnea, wheezing, and cough. It involves various underlying mechanisms such as eosinophilic, neutrophilic, mixed, and pauci-cellular, exercise-induced, occupational, and obesity-related asthma. Asthma is a mostly reversible condition involving several cells and cytokines, leading to chronic airway inflammatory responses, and showing the diversity in asthma phenotypes and complexity. Recent advancements using single-cell RNA sequencing allow distinguishing and analyzing RNA sequences at each cellular level within complex and heterogeneous cell groups. This method has also been applied to study asthma mechanisms, enabling us to predict intercellular interactions triggering asthma and identifying cellular changes characterized by specific molecular-cellular phenotypes. In our study, according to the PRISMA (preferred reporting items from systematic review and meta-analysis) guidelines, we systematically reviewed trends in asthma-related immune and structural cell research using single cell RNA sequencing, highlighting potential therapeutic interventions, and pinpointing opportunities for novel biomarker discovery.

		                        			 It has been reported that some exercise could enhance the anti-viral antibody titers after vaccination including influenza and coronavirus disease 2019 vaccines. We developed SAT-008, a novel digital device, consists of physical activities and activities related to the autonomic nervous system. We assessed the feasibility of SAT-008 to boost host immunity after an influenza vaccination by a randomized, open-label, and controlled study on adults administered influenza vaccines in the previous year. Among 32 participants, the SAT-008 showed a significant increase in the anti-influenza antibody titers assessed by hemagglutination-inhibition test against antigen subtype B Yamagata lineage after 4 wk of vaccination and subtype B Victoria lineage after 12 wk (p<0.05). There was no difference in the antibody titers against subtype “A.” The SAT-008 also showed significant increase in the plasma cytokine levels of IL-10, IL-1β, and IL-6 at weeks 4 and 12 after the vaccination (p<0.05). A new approach using the digital device may boost host immunity against virus via vaccine adjuvant-like effects.
