Musculoskeletal Pain, Physical Activity, Muscle Mass, and Mortality in Older Adults: Results from the Korean Longitudinal Study on Health and Aging (KLoSHA).

Musculoskeletal (MSK) pain significantly impacts physical activity and quality of life in older adults, potentially influencing mortality. This study explored the relationship between MSK pain, physical activity, muscle mass, and mortality among older adults. We studied 1000 participants in the Korean Longitudinal Study on Health and Aging (KLoSHA), a prospective, population-based cohort study of people aged 65 years or older.

Static and Dynamic Biomaterial Engineering for Cell Modulation.

In the biological microenvironment, cells are surrounded by an extracellular matrix (ECM), with which they dynamically interact during various biological processes. Specifically, the physical and chemical properties of the ECM work cooperatively to influence the behavior and fate of cells directly and indirectly, which invokes various physiological responses in the body. Hence, efficient strategies to modulate cellular responses for a specific purpose have become important for various scientific fields such as biology, pharmacy, and medicine.

Efficacy of Combined Antigravity Treadmill and Conventional Rehabilitation After Hip Fracture in Patients With Sarcopenia.

Background: To compare long-term effects of antigravity treadmill (AGT) combined with conventional rehabilitation (CR) and CR after hip fracture in patients with sarcopenia.

Methods: Forty-five patients were randomly allocated to AGT combined with CR (experimental group) or CR (control group) for 10 consecutive working days. Participants were evaluated prior to treatment, 3 weeks, 3 months, and 6 months after treatment.

Evaluating Postoperative Muscle Strength Using Surface Electromyography in Hip Fracture Patient.

Background: To compare the muscle strength of patients with a hip fracture according to the presence of sarcopenia after surgery and the correlation of measured values between a Biodex and surface electromyography (sEMG) in postoperative measurement of muscle strength.

Methods: Seventy-one patients who underwent hip fracture surgery were included in this study. Muscle mass was measured using dual energy X-ray absorptiometry and the grip strength was evaluated using a dynamometer.

Assessment of the Implementation of Critical Pathway in Stroke Patients: A 10-Year Follow-Up Study.

Background: The complications after stroke inhibit functional recovery and worsen the prognosis of patients. The implementation of a critical pathway (CP) can facilitate functional recovery after stroke by enabling comprehensive and systematic structured rehabilitation.

Objective: To evaluate the effects of the implementation of CP in stroke patients for 10 years.

Role of a wireless surface electromyography in dystonic gait in functional movement disorders: A case report.

Background: Dystonic gait (DG) is one of clinical symptoms associated with functional dystonia in the functional movement disorders (FMDs). Dystonia is often initiated or worsened by voluntary action and associated with overflow muscle activation. There is no report for DG in FMDs caused by an abnormal pattern in the ankle muscle recruitment strategy during gait.

Histopathologic analysis of brain metastasis in pulmonary adenocarcinoma: Necrosis is a new risk factor.

Background: Studies have shown that 30-50% of non-small cell lung cancer (NSCLC) patients develop brain metastasis (BM). Since BM shortens overall survival and decreases the quality of life, early detection and treatment of BM are vital. While data are available for clinical risk factors of NSCLC with BM, histopathological factors are not well understood.

Clinical characteristics and outcomes of placental site trophoblastic tumor: experience of single institution in Korea.

Objective: Placental site trophoblastic tumor (PSTT) is the rarest form of gestational trophoblastic disease (GTD) and the optimum management is still controversial. In this study, we analyzed the clinical features, treatment, and outcomes of 6 consecutive patients with PSTT treated in our institution.

Methods: The electronic medical record database of Samsung Medical Center was screened to identify patients with PSTT from 1994 to 2017.
