Effects of exercise mode on improving cardiovascular function and cardiorespiratory fitness after bariatric surgery: A narrative review
Am J Phys Med Rehabil. 2022 Jan 14. doi: 10.1097/PHM.0000000000001946. Online ahead of print.ABSTRACTObesity affects 600 million people globally and increases the risk of developing cardiovascular disease, stroke, diabetes, and cancer. Bariatric surgery is an increasingly popular therapeutic intervention for morbid obesity to induce rapid weight loss and reduce obesity-related comorbidities. However, some bariatric surgery patients, following what is considered a successful surgical procedure, continue to manifest obesity-related health issues, including weight gain, reduced physical function, persistent elevations in bloo...

Progerin-Expressing Endothelial Cells are Unable to Adapt to Shear Stress
In this study we examined how progerin-expressing ECs adapt to fluid shear stress, the principal mechanical force from blood flow. We compared the response to shear stress for progerin-expressing, wild-type lamin A overexpressing, and control ECs to physiological levels of fluid shear stress. Additionally, we also knocked down ZMPSTE24 in ECs, which results in increased farnesylation of lamin A and similar phenotypes to HGPS. Our results showed that ECs either overexpressing progerin or with ZMPSTE24 knockdown were unable to adapt to shear stress, experiencing significant cell loss at a longer duration of exposure to shear...

Reducing the number of test items of the Action Research Arm Test post stroke: A decision tree analysis
Conclusion - A decision tree version of the ARAT was developed, reducing the maximum number of items necessary for ARAT administration from 19 to 4. The scores produced by the decision tree had excellent criterion validity with original ARAT scores.PMID:34998711 | DOI:10.1016/j.apmr.2021.12.011

Rasch Validation and Comparison of the Mini-BESTest and S-BESTest in Patients with Stroke
CONCLUSION: The analyses confirmed that the reliability of S-BESTest was good and unidimensional and that the test provides several improved points, such as item redundancy and local independence of items. Nevertheless, the Mini-BESTest results supported previous findings as a whole and were better than those from the S-BESTest.IMPACT: Rasch analysis demonstrated that the Mini-BESTest was a better balance assessment scale than the S-BESTest for patients with stroke based on its psychometric properties. The Mini-BESTest may serve as a useful scale for assessing balance in patients with stroke, and a keyform plot and strata ...

Epidemiology of stroke and transient ischemic attacks in the population of the territories adjacent to the former Semipalatinsk Nuclear Test Site, Kazakhstan
Radiat Environ Biophys. 2021 Nov 25. doi: 10.1007/s00411-021-00955-1. Online ahead of print.ABSTRACTThe issue of radiation exposure as a potential cause of cerebrovascular disease raises many concerns. The aim of the present study was to investigate the epidemiology of stroke and transient ischemic attacks (TIA) along with the associated risk factors among the population of East Kazakhstan exposed to ionising radiation from the former Semipalatinsk Nuclear Test Site (SNTS) in comparison with the unexposed population of the same region. This 5-year retrospective cross-sectional study included the data on 10,970 patients, of...

Finite element analysis of blood clots based on the non-linear visco-hyperelastic model
This study is focused on the mechanical responses of clots under tensile loading and unloading, because in mechanical thrombectomy, elongation is assumed to occur locally on the clots during the retrieval process. Several types of cylindrical clots were created by changing the fibrinogen dose. Tensile testing revealed that the stiffness (E0.45 value) of clots with fibrinogen could be more than three times higher than that of clots without fibrinogen. It was also found that the stiffness was not proportional to the fibrinogen dose. By fitting to the theoretical curve, it was revealed that the Mooney-Rivlin model could repro...

Learning non-local perfusion textures for high-quality computed tomography perfusion imaging
CONCLUSIONS: The presented NPTN method can obtain high-quality CTP images and estimate high-accuracy CBF map by characterizing more structure details and contrast variants in the CTP image, and outperform the competing methods at low-dose cases.PMID:33910178 | DOI:10.1088/1361-6560/abfc90
