“…The kMRI provides information about dynamic changes in the hypotonic ligamentum flavum and annular bulging, and most importantly reveals the impact of these changes on the spinal cord. 6,17,18 Surgical interventions to relieve spinal cord compression can reduce spinal cord edema, improve spinal cord blood supply, create favorable conditions for the recovery of spinal cord function, and prevent delayed neurological deterioration. The 63 TCCS patients included in this study were treated with surgery and no surgery-related complications occurred after operation.…”

“…21 These results, as well as those from other studies, indicate a minor role of flexion to reducing functional spinal cord impingement. 18 Nevertheless, these previous studies mainly focused on evaluating the dynamic changes in spinal canal stenosis during neck flexion and extension in patients with cervical degenerative disease. By contrast, in the current work, we studied the degree of dynamic cord impingement in patients with TCCS.…”

“…We performed a visual and not a morphometric evaluation of cervical MRI for a number of reasons. Several studies have already performed morphometric analyses about cervical stenosis comparing spinal canal and spinal cord diameters along with CSF signal around the cord or angles [13,25]. Moreover, due to the highly mobile nature of the cervical spine and the fact that usually most MRIs are obtained only in one single position, dynamic cord compression can be an elusive diagnosis that is often missed and not well-understood [29] especially when stenosis involves several levels.…”

Objective Cervical spondylotic myelopathy (CSM) is caused by cervical spine degeneration and surgery may be beneficial, but selection for surgery might be challenging. We performed a multimodal analysis to assess predicting factors that may be useful to help surgeons in this choice. Patients and methods We retrospectively evaluated clinical, motor evoked potentials (MEP), and MRI data of patients who undergone surgery for CSM. Seventy-six consecutive patients (46 males) were enrolled. The median age was 65.5 [IQR: 57–71] years, and the duration of symptoms was 11 [8–13] months. A multivariate analysis in order to assess predictors of outcome and ROC curve analysis were performed. Results Thirty patients (M:18, 39.5%) gained 6 or more points on mJOA and they were collected in good recovery group, whereas 46 patients (60.5%, M:28) showed a fair recovery. We developed a comprehensive score system (CSS) taking into account clinical, neurophysiological, and neuroradiological data. ROC curve analysis was performed to determine the discriminative power of four models derived from the multivariate logistic regression analysis for predictors of good outcome considering only clinical variables, MRI variables, and MEP variables or considering the comprehensive model, demonstrating a good accuracy of CSS model to predict outcome. Conclusion This study demonstrates that CSS model taking into consideration functional assessment by mJOA score, neurologic evaluation, cervical MRI, and MEP may be a feasible method to predict outcome in patients candidate to surgery, supporting surgeon’s decisions both for those patients candidate to surgery and for patients in whom a “wait and see” approach could be proposed.

“…Sixthly, stream order was extracted based on theory. Finally, some extreme outlet points were selected of the concerned river, and based on counting outlet points the watershed basins were delineated (Ameri et al, 2018;Amiri et al, 2019;Tykocki et al, 2018).…”

Water is an important resource of the earth’s surface and it is integral for all on this planet. The availability or the scarcity of water depends on the watershed characterizes that consider the basic, linear, and shape parameters of any waterbody. The objective of the study was to delineate 14 morphometric parameters in the Barind region (Dinajpur district, Bangladesh) for sustainable hydrological modeling. An ASTER-DEM of 30-meter resolution data, geographical information system (GIS), and Remote sensing technique were used for extracting drainage components of interest region. The whole study region was covered by the flow of the Purnovoba river, Jamuna river, Atrai river (part-1 and part-2). Research results found that the Purnovoba river had a high bifurcation ratio (0.9982) that defined hydrologically more disturbed than the other three watershed areas and it had a high stream frequency (0.8332) that denoted rocky having low infiltration capacity. Jamuna river had a low drainage density (0.7322) that defined more vegetation having higher permeability. Besides, the Jamuna river had the lowest no. of stream order that was insignificant in the steady runoff process and less prone to cause a flash flood. The research predicted that the availability of groundwater might decrease to Jamuna river in the future as it had the lowest basin area (217.42 sqr. km ) and perimeter (114.90 km) and the basin surface slope would become gentle to Atrai river part-1 for the lowest length of overland flow (0.6072). Purnovoba river experienced the lowest form factor (0.2351) which indicated the most possibility for erosion. The elongated ratio of all basins was greater than 0.5 which considered all the shapes were more elongated. These findings will help for further modeling of an integrated watershed for sustainable hydrological models in the Barind region.
