Objectives: Previous studies have shown that combined interventions involving cognitive training and physical activity are effective in enhancing brain function. This study examined the effects of a dual-task intervention—simultaneously combining cognitive and physical tasks—on the cognitive and physical function of community-dwelling older adults aged 65 years and older. Methods: From July to December 2023, cognitively normal adults aged 65 years or older were recruited through the Jeollabuk-do Regional Dementia Center. Participants completed an eightsession group-based program (60 minutes per session) that combined cognitive training and physical activity. The cognitive functions were evaluated using a neuropsychological test battery, and the physical functions were assessed using the Short Physical Performance Battery (SPPB), before and after the intervention. Results: Of 79 participants, 73 completed the intervention. After the program, significant improvements in orientation, memory, visuoconstruction, naming, total cognitive scores, and performance were observed on the Trail Making Test-Part A and Trail Making Test-Part B (p<0.05 to p<0.001).Physical performance also significantly improved the balance, gait speed, chair-stand ability, and total SPPB scores (p<0.001). Multiple regression analysis showed that lower educational attainment and cohabitation with children were associated with greater cognitive improvements, while antihypertensive medication use was negatively associated, and diabetes medication use was positively associated with cognitive outcomes. Conclusion Simultaneous dual-task–based combined intervention may be an effective strategy for enhancing the cognitive and physical functions in cognitively preserved older adults. Nevertheless, further studies will be needed to explore its long-term effects and underlying neurobiological mechanisms.

Tracheal bronchus is an uncommon anomaly in which an ectopic bronchus originates directly from the supracarinal trachea. It is usually an asymptomatic anatomical variant incidentally found on computed tomography or bronchoscopy. However, it can present with symptoms, such as chronic cough, wheezing, atelectasis, and recurrent pneumonia. We report a case of tracheal bronchus diagnosed in the neonatal period, in which the term baby presented with respiratory distress and persistent pulmonary hypertension of the newborn after birth, but no other congenital anomaly was found on further evaluation.

BACKGROUND AND OBJECTIVES: Marfan syndrome (MFS) is a connective tissue disorder with autosomal dominant inheritance and a highly variable clinical spectrum. However, there are limited data available on the clinical features of Korean patients with MFS. The aim of the present study was to describe the clinical characteristics and outcomes of Korean patients with MFS. SUBJECTS AND METHODS: We included all patients who were diagnosed with MFS between January 1995 and May 2015 at a single tertiary medical center. Patients with an MFS-related disorder including MASS phenotype (myopia, mitral valve prolapse, borderline and non-progressive aortic root dilatation, skeletal findings, and striae), mitral valve prolapse syndrome, and ectopia lentis syndrome were excluded. A total of 343 Korean patients aged ≥15 years who satisfied the revised Ghent nosology were included. RESULTS: The mean patient age at diagnosis was 35.9±12.6 years and 172 (50.1%) patients were male. Median follow-up duration was 52.8 months. A total of 303 patients (88.6%) had aortic root dilatation with Z score ≥2 or aortic root dissection. Ectopia lentis was relatively less common (163 patients, 55.1%) and systemic score ≥7 was found in 217 patients (73.8%). Among 219 probands, a family history of MFS was present in 97 patients (44.5%) and sporadic cases in 121 patients (55.5%). Among the 157 probands who underwent genetic analysis, 141 (89.8%) had an FBN1 mutation associated with aortic root aneurysm/dissection. Aortic dissection (AD) or intramural hematoma (IMH) was identified in 110 patients (32.1%). Among the 221 patients without AD or IMH, descending aortic aneurysms were identified in 19 patients (8.6%). Two hundred thirteen patients (62%) underwent cardiovascular surgery of any type. Eight patients died during follow-up. CONCLUSION: We described the clinical characteristics and outcomes of Korean MFS patients. Cardiovascular manifestations were commonly detected and FBN1 mutation was present in approximately 90% of patients. In contrast, ectopia lentis was identified in approximately half of patients. Our findings will be informative for the evaluation of patients with MFS.

The objectives of this study were to assess the clinical outcomes of adults with Ebstein Anomaly (EA) according to their treatment modalities. All adult EA patients diagnosed between October 1994 and October 2014 were retrospectively evaluated by medical record review. Total 60 patients were categorized into 3 groups according to their treatment strategy, i.e. non-operative treatment (Group I, n = 23), immediate operative treatment (Group II, n = 27), and delayed operative treatment (Group III, n = 10). A composite of major adverse cardiac and cerebrovascular events (MACCE) and factors associated with MACCE were assessed in each treatment group. MACCE occurred in 13.0% patients in Group I, 55.6% patients in Group II and 50% in Group III (P = 0.006). Event free survivals at 5 years were 90% in Group I, 52.7% in Group II, 50.0% in Group III (P = 0.036). Post-operatively, most patients showed improvement on clinical symptoms. However, event free survival rate was lower in patients with operation compared to those with non-operative treatment (58.7% vs. 90.9%; P = 0.007). Major arrhythmic event occurred more frequently even after surgical ablation (50.0% vs. 20.0%; P = 0.034). Re-operation was more frequent in patients underwent delayed surgery compared to those with immediate surgery (50.0% vs. 18.5%; P = 0.001). Current guideline to decide patient's treatment strategy appeared to be appropriate in adult patients with EA. However, surgical ablation for arrhythmia was not enough so that concomitant medical treatment should be considered. Therefore, attentive risk stratification and cautious decision of treatment strategy by experienced cardiac surgeon are believed to improve clinical outcome.
