In this study, we developed and assessed band-embedded laterally wedged insoles designed to correct genu varum, a condition characterized by outwardly bent knees. The product was specifically developed to improve usability and wearability in both indoor and outdoor conditions, addressing the key limitations of existing correction products. The wedged insoles were integrated so the band could promote proper alignment by redistributing the body weight toward the medial side of the legs, thereby reducing knee strain. Through detailed testing, the band demonstrated an average reduction of 14.76% in the gap between the knees, indicating significant corrective efficacy. Among the three developed designs, the hooks-and-loop-based band appeared to be the most effective, achieving a 15.94% reduction in the gap between the knees and receiving the highest scores in user satisfaction regarding design, functionality, comfort, and ease of use. The use of breathable lightweight materials and a design that accommodates both barefoot and shod conditions ensures long-term comfort and practicality. This product provides a practical, versatile, and user-friendly solution for genu varum correction and a foundation for further advancements in corrective orthopedic design.

BackgroundApolipoprotein E (APOE) gene polymorphism is associated with neurodegenerative and cardiovascular diseases. Although the effects of the gene differ by ethnic group, few studies have examined Asians. Therefore, the association between APOE polymorphism and mortality in Koreans was evaluated in this study.MethodsThis study population included participants from the Dong-gu and Namwon Studies. APOE genotypes were categorized as E2 (E2/E2 and E2/E3), E3 (E3/E3), and E4 (E3/E4 and E4/E4). Multivariate Cox proportional hazard models were constructed using the E3 allele as a reference.ResultsIn the model adjusting for study site, age, gender, and lifestyle, the hazard ratio (HR) of mortality for those with the E4 allele was 1.08 (95% confidence interval [CI], 0.97–1.20), while that for those with the E2 allele was 0.84 (95% CI, 0.74–0.96). After adjusting for blood lipids to evaluate their mediating effects, the HRs of mortality for those with E4 and E2 alleles were 1.08 (95% CI, 0.97–1.20) and 0.80 (95% CI, 0.70–0.92), respectively. These associations were more evident in younger groups, with HRs of 0.70 (95% CI, 0.52–0.92) for the E2 allele and 1.25 (95% CI, 1.03–1.53) for the E4 allele.ConclusionIn two large population-based cohort studies, the E2 allele was associated with a lower risk of mortality compared with the E3 allele, whereas the E4 genotype was not associated with mortality in Koreans.

The purpose of this study was to resolve, in an efficient manner, the mechanoreceptor problems of the part far from the paretic upper extremity in stroke patients, as well as to provide clinical basic data of an intervention program for efficient neurodynamic in stroke patients, by developing a rhythmic neurodynamic exercise program and verifying functional changes depending on the increase in the upper extremity nerve conduction velocity.

Although most of sacral perineural cysts are asymptomatic, some may produce symptoms. Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain.

The increasing worldwide incidence of extensively drug-resistant tuberculosis (XDR-TB) has emerged as a threat to public health and tuberculosis (TB) control. Treatment outcomes have varied among studies, and data on long-term survival are still scarce. To retrospectively assess the burden, clinical characteristics, treatment outcomes, and long-term survival rate of patients with XDR-TB in a cohort of patients with HIV-negative multidrug-resistant tuberculosis (MDR-TB) in South Korea. Medical records were reviewed of patients newly diagnosed with or retreated for MDR-TB from 2000 to 2002. The cohort was monitored for 3 to 7 years after the initiation of treatment. Initial treatment outcomes and cumulative survival rates were analyzed, and predictors of treatment success and survival were defined. Of 1,407 patients with MDR-TB 75 (5.3%) had XDR-TB at treatment initiation. The default rate was high (453/1,407; 32%), and patients with XDR-TB had lower treatment success (29.3 vs. 46.2%; P = 0.004) and higher all-cause (49.3 vs. 19.4%; P < 0.001) and TB-related disease mortality (41.3 vs. 11.8%; P < 0.001) than other patients with MDR-TB. The presence of XDR-TB significantly affected treatment success (odds ratio, 0.23; 95% confidence interval [CI], 0.08-0.64; P = 0.005), all-cause mortality (hazards ratio, 3.25; 95% CI, 1.91-5.53; P < 0.001), and TB-related mortality (hazards ratio, 4.45; 95% CI, 2.48-8.00; P < 0.001) on multivariate analyses. XDR-TB occurred in a substantial proportion of patients with MDR-TB in South Korea, and was the strongest predictor of treatment outcomes and long-term survival in patients with MDR-TB. Adequate TB control policies should be implemented to prevent the further development and spread of drug resistance.
