Determination of the Predictors with the Greatest Influence on Walking in the Elderly.

Previous studies have revealed that independent variables (lower extremity strength, postural control ability, and body composition) influence gait performance and variability, but the difference in the relative influence between these variables is unclear. Hence, this study determines the variable that is the most influential predictor of gait performance and variability among potential independent variables in the elderly. Seventy-eight subjects aged ≥60 years participated.

Promotion of Adequate Exercise for Chronic Disorders' Elderly Through Paced Music.

South Korean population has been aging at an accelerated rate in recent years and the country will be a hyper-aging nation at 2020. One important issue in an aged society is higher rates of chronic disorders among the population. One of the best means to prevent an increase in severity of chronic disease is making patients exercise regularly.

[Purpose] This study aimed to determine the effect of forward head posture-improving exercises on rounded shoulder posture when employing the self-stretch exercise, the McKenzie exercise, and the Kendall exercise as intervention methods based on previous studies that reported negative effects of unbalanced posture and musculoskeletal problems on forward head posture and rounded shoulder posture. [Subjects and Methods] The selected 28 subjects were randomly assigned into the McKenzie exercise group (n=9), the self-stretch exercise group (n=10), and the Kendall exercise group (n=9). To compare the forward head posture, the craniovertebral angle was used.

Applicability of BCLC stage for prognostic stratification in comparison with other staging systems: single centre experience from long-term clinical outcomes of 1717 treatment-naïve patients with hepatocellular carcinoma.

Background: The most informative staging system regarding survival outcomes for treatment-naïve hepatocellular carcinoma (HCC) remains debated. We evaluated prognostic values of Barcelona Clinic Liver Cancer (BCLC) stage compared with other staging systems, and identified discrepancies between treatment options chosen in Korean clinical practice and BCLC guidelines.

Methods: Between 2003 and 2008, 1717 prospectively enrolled patients with treatment-naïve HCC were analysed.

18F-fluorodeoxyglucose uptake on positron emission tomography as a prognostic predictor in locally advanced hepatocellular carcinoma.

Background: Metabolic activity assessed by (18)F-fluorodeoxyglocuse-positron emission tomography ((18)F-FDG-PET) reflects biological aggressiveness and prognoses in various tumors. The authors present a correlation between tumor metabolic activity and clinical outcomes in patients with hepatocellular carcinoma (HCC).

Methods: Over a 3-year period (2005-2008), 135 locally advanced HCC patients were treated with localized concurrent chemoradiotherapy (CCRT; external beam radiotherapy at 45 grays for 5 weeks plus concurrent hepatic arterial infusion of 5-fluorouracil during the first and fifth week) followed by repetitive hepatic arterial infusional chemotherapy with 5-fluorouracil and cisplatin.

Early α-fetoprotein response as a predictor for clinical outcome after localized concurrent chemoradiotherapy for advanced hepatocellular carcinoma.

Backgrounds: There are limitations in using only radiological criteria to evaluate treatment outcomes in hepatocellular carcinoma (HCC). α-fetoprotein (AFP) is regarded as an indicator of tumour activity in HCC.

Aims: We present a novel correlation between AFP response and survival outcome in patients treated with localized concurrent chemoradiotherapy (CCRT).

Endovascular treatment of isolated common iliac artery aneurysms with short necks using bifurcated stent-grafts.

Elective surgical repair has traditionally been considered to be the treatment of choice for the exclusion of isolated iliac artery aneurysms (IAAs). Recently, endovascular repair has evolved as an alternative to surgical repair, especially in patients at high surgical risk. However, in the absence of sufficient proximal necks, iliac artery aneurysms are not suitable for direct deployment of a tubular-shaped endograft.
