Introduction: This study primarily investigates the impact of a 6-week Sprint Interval Training (SIT) intervention on the physical fitness test results of male university students, as well as the dose-response relationship in adjusting the experimental protocol.

Methods: A total of 26 male university students (aged 20 ± 2 years; height 174 ± 7 cm; weight 70 ± 14 kg; mean ± SD) with no systematic training in the past 3 months, no physiological diseases, and healthy physical condition voluntarily participated in the experiment. The SIT protocol was designed based on a classic Wingate sprint protocol (4-6 x 30 s sprints with 4 m of recovery), and adjustments were made based on the participants' actual adaptation.

This study investigated anatomical and procedural factors influencing iliac limb migration and its correlation with late type 1b and type 3 endoleaks. We analyzed data of 141 iliac limbs from 91 patients who underwent endovascular aneurysm repair for infrarenal abdominal aortic aneurysm between 2005 and 2017. Iliac limb migration was measured using initial and follow-up computed tomography angiography scans conducted at least three years post-procedure, with significant migration defined as a change of ≥ 5 mm.

Rationale: Endovascular coil embolization for wide-neck intracranial aneurysms is technically challenging and requires supporting devices. Intracranial stents are widely used as a buttress for compact coil filling and preventing coil protrusion into the parent artery. Horizontal stenting has been developed to maximize coil insertion and reduce the risk of thromboembolism.

Background: Total knee arthroplasty (TKA) is a treatment option for osteoarthritis of the knee. After undergoing TKA, patients can be treated with continuous passive motion (CPM); however, inconsistent results have been reported on the effectiveness of CPM as part of a rehabilitation strategy. This discrepancy may be due to the difference between the set-arc of CPM and real arcs of knee motion.

Article Synopsis
  • - Post-stroke cognitive impairment (PSCI) significantly impacts many stroke patients, increasing their risk of mortality, dependency, and needing long-term care.
  • - Early identification of risk factors for PSCI and the initiation of cognitive rehabilitation can improve patients’ quality of life and lessen the burden on their families.
  • - Most PSCI risk factors are non-modifiable, but managing stroke risk factors can be controlled; further research is needed to explore effective cognitive rehabilitation programs.

Introduction: Sarcopenia associated with stroke can significantly impact patient prognosis; however, the current standard diagnostic methods for sarcopenia are rarely used in stroke patients. Therefore, the aim of the current study was to investigate whether the temporal muscle thickness (TMT) or area (TMA) could serve as a surrogate marker for measuring skeletal muscle mass.

Methods: This retrospective chart review study was conducted on 244 participants from March 2018 to February 2020.

Coronary artery calcification (CAC) on lung cancer screening low-dose chest CT (LDCT) is a cardiovascular risk marker. South Korea was the first Asian country to initiate a national LDCT lung cancer screening program, although CAC-related outcomes are poorly explored. The purpose of this article is to evaluate CAC prevalence and severity using visual analysis and artificial intelligence (AI) methods and to characterize CAC's association with major adverse cardiovascular events (MACEs) in patients undergoing LDCT in Korea's national lung cancer screening program.

Background: Osteosarcopenia is geriatric syndrome defined as the concomitant occurrence of osteopenia/osteoporosis, and sarcopenia. Osteosarcopenia is a relatively new concept in geriatric medicine; however, it may increase the risk of fragility fractures, several morbidities and mortalities, and socioeconomic costs. Although resistance exercises and nutritional support-including protein, calcium, and vitamin D-are potential non-pharmacological management procedures, evidence is still lacking.

Transarterial chemoembolization (TACE) was introduced in 1977 with the administration of chemotherapeutic agent to gelatin sponge particles through the hepatic artery in patients with hepatocellular carcinoma (HCC) and was established as conventional TACE using Lipiodol in the 1980s. In the 2000s, drug-eluting beads were developed and applied clinically. Currently, TACE is a commonly used non-surgical treatment modality for patients with HCC who are unsuitable for curative treatment.
