Objective:
To evaluate the predictive performance of anthropometric indices for metabolic syndrome (MetS) among Chinese adolescents with different nutritional status.
Methods:
We recruited 9,513 adolescents aged 10-18 years from seven provinces in China during September 2014. Anthropometric indices and blood pressure were measured at recruitment, and blood samples were collected for determining fasting plasma glucose and lipid profile. Receiver operating characteristic (ROC) analyses were used to assess the predictive performance of anthropometric indices, including body mass index (BMI) percentile, waist circumference percentile, waist-height ratio, and waist-hip ratio.
Results:
Overall, the four anthropometric indices showed good accuracy for predicting MetS with areas under ROC curves (AUCs) ranging from 0.86 to 0.94; similar AUCs ranging from 0.73 to 0.99 were observed for participants with normal weight. The performance of all four indices was poor in overweight and obese participants, with AUCs ranging from 0.66 to 0.77 and from 0.60 to 0.67, respectively. Waist circumference showed relatively better performance in all the subgroup analyses.
Conclusions
We suggest using anthropometric indices with the cutoff values presented here for predicting MetS in the overall and normal-weight adolescent population, but not in the overweight and obese adolescent population where more specific screening tests are required.

Robots are being used to assist the recovery of walking ability for patients with neurologic disorders. This study aimed to evaluate the feasibility and functional improvement of training with robot-assisted gait training (RAGT) using the Morning Walk®, an end-effector type robot using footplates and saddle seat support. A total of 189 individuals (65.1% men, 34.9% women; mean age, 53.2 years; age range: 5–87 years) with brain lesions, spinal cord injuries, Parkinson's disease, peripheral neuropathies, and pediatric patients were involved in this retrospectively registered clinical trial. Each participant performed 30 minutes of RAGT, five times a week, for a total of 24 sessions. Failure was defined as an inability to complete all 24 sessions, and the reasons for discontinuation were analyzed. Parameters of Medical Research Council scales and Functional Ambulation Categories were analyzed before and after RAGT training. Among the 189 patients, 22 (11.6%) failed to complete the RAGT. The reasons included decreased cooperation, musculoskeletal pain, saddle seat discomfort, excessive body-weight support, joint spasticity or restricted joint motion, urinary incontinence from an indwelling urinary catheter, and fatigue. Comparison between the pre- and post-training motor and ambulatory functions showed significant improvement. The result of the study indicates that the Morning Walk® is feasible and safe and useful for functional improvement in patients with various neurologic disordersTRIAL REGISTRATION: Clinical Research Information Service Identifier: KCT0003627

This study investigated how physical and cognitive function and psychological factors affected the health-related quality of life (HRQoL, hereafter HQ) of stroke patients in South Korea. The study enrolled 32 right-handed subjects with chronic cerebral infarction with disability and preserved cognitive function (Mini-Mental State Examination ≥ 20). Physical disability was assessed using the modified Rankin Scale (mRS) and Korean modified Barthel Index (KMBI). Quality of life was measured using the World Health Organization Quality of Life-Abbreviated form (WHOQOL-BREF, hereafter WB) and the 36-Item Short-form Health Survey (SF-36) in face-to-face interviews. Psychological distress was investigated using the Beck Depression Inventory Scale-II. The associations of each domain of WB and SF-36 were investigated using Pearson correlation analyses. Physical disability was negatively correlated with HQ in the SF-36. The physical function and bodily pain scales of the SF-36 were negatively correlated with physical disability. The general health domain of the SF-36 was negatively correlated with psychological scores. Emotional status was associated with physical health, social relationships, and general health in HQ. In summary, the severity of physical disability was associated with the patient's general and physical health and body pain. These findings suggest the importance of psychological, cognitive, and physiological interventions for improving the quality of life of patients after cerebral infarction.

We measured the difference of sitting pressure between the affected and unaffected sides (DSPAU) using sitting pressure measured with a force platform to identify sitting imbalance. The aim of this study is to investigate the relations between sitting balance and functional status or parameters according to characteristics stroke patients. We examine changes in DSPAU and functional assessment before and after a 3 week of rehabilitation in hemiplegic stroke patients (n = 73). These pre- and post-treatment data according to stroke characteristics, and correlations between the DSPAU and functional scales were analyzed. The DSPAU was greater in the non-ambulatory group compared to the ambulatory group, in patients who scored lower in the Medical Research Council (MRC) scores, and in patients whose the MRC scores for the lower limbs were lower than of the upper limbs. We observed that a decrease in the DSPAU was associated with an improvement in functional assessment parameters following rehabilitation. Further, changes in DSPAU were significantly correlated to the Modified Barthel Index. We observed that a decrease in DSPAU was associated with an improvement in functional parameters following rehabilitation. In conclusion, repeated measurements of sitting balance using DSPAU may be helpful to predict motor and functional recovery in stroke patient with hemiplegia.

OBJECTIVE: To assess whether virtual expiratory (VE)-computed tomography (CT)/ultrasound (US) fusion imaging is more effective than conventional inspiratory (CI)-CT/US fusion imaging for hepatic interventional procedures. MATERIALS AND METHODS: This prospective study was approved by the Institutional Review Board, and informed consent was obtained from each patient. In total, 62 patients with focal hepatic lesions referred for hepatic interventional procedures were enrolled. VE-CT images were generated from CI-CT images to reduce the effects of respiration-induced liver motion. The two types of CT images were fused with real-time US images for each patient. The operators scored the visual similarity with the liver anatomy upon initial image fusion and the summative usability of complete image fusion using the respective five-point scales. The time required for complete image fusion and the number of point locks used were also compared. RESULTS: In comparison with CI-CT/US fusion imaging, VE-CT/US fusion imaging showed significantly higher visual similarity with the liver anatomy on the initial image fusion (mean score, 3.9 vs. 1.7; p < 0.001) and higher summative usability for complete image fusion (mean score, 4.0 vs. 1.9; p < 0.001). The required time (mean, 11.1 seconds vs. 22.5 seconds; p < 0.001) and the number of point locks (mean, 1.6 vs. 3.0; p < 0.001) needed for complete image fusion using VE-CT/US fusion imaging were significantly lower than those needed for CI-CT/US fusion imaging. CONCLUSION: VE-CT/US fusion imaging is more effective than CI-CT/US fusion imaging for hepatic interventional procedures.

OBJECTIVE: The purpose of this study was to investigate whether three-dimensional (3D) magnetic resonance imaging could improve diagnostic accuracy for suspected posterior ligamentous complex (PLC) disruption. MATERIALS AND METHODS: We used 20 freshly harvested goat spine samples with 60 segments and intact surrounding soft tissue. The animals were aged 1–1.5 years and consisted of 8 males and 12 females, which were sexually mature but had not reached adult weights. We created a paraspinal contusion model by percutaneously injecting 10 mL saline into each side of the interspinous ligament (ISL). All segments underwent T2-weighted sagittal and coronal short inversion time inversion recovery (STIR) scans as well as coronal and sagittal 3D proton density-weighted spectrally selective inversion recovery (3D-PDW-SPIR) scans acquired at 1.5T. Following scanning, some ISLs were cut and then the segments were re-scanned using the same magnetic resonance (MR) techniques. Two radiologists independently assessed the MR images, and the reliability of ISL tear interpretation was assessed using the kappa coefficient. The chi-square test was used to compare the diagnostic accuracy of images obtained using the different MR techniques. RESULTS: The interobserver reliability for detecting ISL disruption was high for all imaging techniques (0.776–0.949). The sensitivity, specificity, and diagnostic accuracy of the coronal 3D-PDW-SPIR technique for detecting ISL tears were 100, 96.9, and 97.9%, respectively, which were significantly higher than those of the sagittal STIR (p = 0.000), coronal STIR (p = 0.000), and sagittal 3D-PDW-SPIR (p = 0.001) techniques. CONCLUSION: Compared to other MR methods, coronal 3D-PDW-SPIR provides a more accurate diagnosis of ISL disruption. Adding coronal 3D-PDW-SPIR to a routine MR protocol may help to identify PLC disruptions in cases with nearby contusion.

OBJECTIVE: To investigate the usefulness of computed tomography (CT) texture analysis (CTTA) in estimating histologic tumor grade and in predicting disease-free survival (DFS) after surgical resection in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Eighty-one patients with a single HCC who had undergone quadriphasic liver CT followed by surgical resection were enrolled. Texture analysis of tumors on preoperative CT images was performed using commercially available software. The mean, mean of positive pixels (MPP), entropy, kurtosis, skewness, and standard deviation (SD) of the pixel distribution histogram were derived with and without filtration. The texture features were then compared between groups classified according to histologic grade. Kaplan-Meier and Cox proportional hazards analyses were performed to determine the relationship between texture features and DFS. RESULTS: SD and MPP quantified from fine to coarse textures on arterial-phase CT images showed significant positive associations with the histologic grade of HCC (p < 0.05). Kaplan-Meier analysis identified most CT texture features across the different filters from fine to coarse texture scales as significant univariate markers of DFS. Cox proportional hazards analysis identified skewness on arterial-phase images (fine texture scale, spatial scaling factor [SSF] 2.0, p <001; medium texture scale, SSF 3.0, p <001), tumor size (p = 0.001), microscopic vascular invasion (p = 0.034), rim arterial enhancement (p = 0.024), and peritumoral parenchymal enhancement (p = 0.010) as independent predictors of DFS. CONCLUSION: CTTA was demonstrated to provide texture features significantly correlated with higher tumor grade as well as predictive markers of DFS after surgical resection of HCCs in addition to other valuable imaging and clinico-pathologic parameters.

PURPOSE: To analyze and compare the clinical factors and neurodevelopmental outcomes compare early- and late-onset periventricular leukomalacia (PVL) in very low birth weight infants (VLBWI). METHODS: We performed a retrospective study involving 199 newborn infants weighing < 1,500 g admitted to the neonatal intensive care unit between March 2009 and December 2015. VLBWI with PVL were categorized into early- and late-onset PVL groups based on the time of diagnosis based on 28 days of age. We analyzed the clinical factors and neurodevelopmental outcomes between the groups. RESULTS: The incidence rate of PVL was 10.1% (16/158). The Apgar score at 1 minute and the mean duration of tocolytic therapy were associated with the development of PVL. The incidence rate of premature rupture of membranes (PROM) was significantly higher in the early-onset PVL group (P=0.041). No significant differences were observed in neurodevelopmental outcomes between the early- and late-onset PVL groups. CONCLUSION: Results suggest that a higher incidence of PROM was associated with clinical characteristics in the early-onset PVL group. No significant intergroup differences were observed in neurodevelopmental outcomes; however, the Bayley Scales of Infant Development-III scores were lower in the early-onset PVL group.

OBJECTIVE: The present study compared cancer-related fatigue (CRF) and chronic fatigue syndrome (CFS) using multidimensional measurements with the aim of better understanding characteristics and exploring markers of two similar fatigue syndromes. METHODS: Twenty-five patients with CRF and twenty patients with CFS completed questionnaires, including the Fatigue Severity Scale (FSS), Hospital Anxiety Depression Scale (HADS), Perceived Stress Scale (PSS), and Pittsburgh Sleep Quality Index (PSQI). Additionally, levels of high sensitivity C-reactive protein (hs-CRP), heart rate variability (HRV), and electroencephalography (EEG) were obtained. Neurocognitive functioning was also evaluated. RESULTS: Both groups showed comparable levels of psychological variables, including fatigue. Compared to CFS subjects, CRF patients had significantly higher hs-CRP levels and a reduced HRV-index. The within-group analyses revealed that the FSS score of the CRF group was significantly related to scores on the HADS-anxiety, HADS-depression, and PSQI scales. In the CFS group, FSS scores were significantly associated with scores on the PSS and the absolute delta, theta, and alpha powers in frontal EEG. CONCLUSION: Findings indicate that different pathophysiological mechanisms underlie CFS and CRF. Inflammatory marker and HRV may be potential biomarkers for distinguishing two fatigue syndromes and frontal EEG parameters may be quantitative biomarkers for CFS.
