ness of robotic therapy in promoting mechanisms that facilitate re-learning and motor recovery in patients with post-stroke chronic disabilities. However, future studies should overcome the limitations of heterogeneity found in the current literature, by proposing a greater number of high-level RCTs, to better understand the mechanisms of robot-induced neuroplasticity, follow the clinical progress, estimate a prognosis of recovery of motor function, and plan a personalized rehabilitative programme for the patients.Focal muscular vibration (FMV) is a non-invasive technique that showed positive effects on spasticity of the upper limb in stroke subjects but different protocols have been proposed so the studies are not comparable and, to date, it is not clear which muscles should be treated, agonist, or antagonist muscles to obtain the better result on spasticity. The objective of this study is to evaluate the effects on spasticity of FMV on the upper limb flexor spastic muscles compared to the effects of FMV on the upper limb extensor muscles in subacute stroke patients. We treated 28 subacute stroke patients (mean age 64.28±13.79) randomized into two groups Group A and Group B. Group A was treated by applying FMV to the flexor muscles of the upper limb, while Group B was treated by applying FMV to the extensor muscles of the upper limb. The effects on spasticity were assessed by Modified Ashworth Scale (primary outcome) and the upper limb motor function by instrumental robotic outcomes; moreover, muscle strength and pain protocol can determine an improvement in muscle tone and in the Duration to perform a task, regardless of the muscles treated, while the pain improves if we treat the agonist muscles.
The calculation of centroids from profile mass spectra is one of the very first steps in the processing of mass spectra. The output is a signal and a m/z value. We focus on the accuracy of the prediction of the centroids' m/z values.

A calculation based on the Savizky-Golay algorithm was evaluated on an Orbitrap mass spectrum. Reference m/z values were identified manually. Experimental centroids were extracted (1) automatically using our algorithm or the MSconvert algorithm and (2) manually using the Xcalibur software from Thermo. The three series of experimental m/z values were compared with the reference m/z values.

Our algorithm improved the determination of the m/z values compared with MSconvert. However, no improvement was observed over Xcalibur.

Our algorithm improved the automatic estimation of m/z values in the profile-to-centroid calculation. This is of importance when the goal is to determine raw compositions from the experimental m/z values. Nevertheless, the algorithms led to almost the same m/z values on a higher resolution mass spectrum.

This study explored the SPECTRA's construct validity using a wide range of life event (extra-test) variables in a clinical sample. The life event variables included the following education level, school failure, childhood adversity, suicide attempts, psychiatric hospitalizations, depression, psychotic symptoms, self-injury, substance abuse, arrests, physical violence, marital status, employment status and current medications. Results showed that all SPECTRA clinical scales had significant life event correlations. For the higher-order Spectra scales, the global index of psychopathology had the greatest number and range of life event correlations. Correlations for the externalizing and reality impairing Spectra scales provided solid validity evidence, while correlations for the internalizing Spectra scale were more diffuse. These findings provide the first non-test-based evidence of construct validity for the SPECTRA.
 The surgical approach for cervical spondylotic radiculopathy (CSR) is controversial. This study aims to investigate the effectiveness of the combined anterior cervical diskectomy and fusion (ACDF) and uncovertebrectomy for treatment of CSR.

 This is a retrospective case control study. One hundred and forty-six patients with CSR who underwent two different procedures (ACDF alone [group A]) and a combination of ACDF and uncovertebrectomy [group B]) from March 2008 to April 2013 were included. The operation time, blood loss, Visual Analog Scale scores of the neck (VAS-neck) and arm (VAS-arm), Neck Disability Index (NDI) score, 36-Item Short Form Health Survey (SF-36) score, fusion segment curvature, global cervical curvature, and the rate of surgical complication were evaluated.

 There were no significant differences in the basic demographic and clinical characteristics between the two groups (
 > 0.05). No significant differences were noticed in the fusion segment curvature and global cervical curvature between the two groups (
 > 0.05). Whereas the operation time and blood loss in group B were greater than those in group A (
 < 0.05), the VAS-neck, VAS-arm, NDI, and SF-36 scores were better in group B (
 < 0.05). The surgical complication rate between the two groups was not significantly different (
 > 0.05).

 Clinical efficacy of ACDF plus uncovertebrectomy for the treatment of patients with CSR may be better than that of ACDF alone, but at the expense of more operation time and blood loss.

 Instrumentation in spinal revision surgery is considered challenging. Altered or missing anatomical landmarks hinder the surgeons' intraoperative orientation. In recent history, the importance of navigated approaches to spinal screw placement is constantly increasing. A growing number of medical centers have introduced intraoperative CT (iCT) navigation as a new clinical standard. In this study, we compare the accuracy of dorsal iCT-navigated instrumentation in revision surgery versus primary interventions.

 Between September 2017 and January 2019, we prospectively analyzed a consecutive series of dorsal instrumentation using iCT. Patients with previous operative interventions in the relevant spinal segments were included in the revision group and compared with a previously assessed group of primary interventions (nonrevision group). Each screw was assessed individually by an independent observer, making use of a modified Gertzbein and Robbins classification.

 In this period, 39 patients were treated in the revision group with a total amount of 269 implanted screws. We achieved an overall accuracy of 95.91% compared with 95.12% in the nonrevision group (46 patients, 287 screws). We found no significant difference in accuracy between the two groups or any anatomical region of the spine.

 In summary, iCT-navigated screw placement yields a good accuracy in spinal revision surgery, without significant difference to primary interventions.

 Primary Ewing's sarcoma of the skull is a very rare malignant neoplasm, predominantly occurring in children and adolescents. We describe here the clinical, neuroradiologic, and histopathologic features of a patient with primary Ewing's sarcoma of the skull and discuss the standards of therapy for this type of tumor.

 This 18-year-old male patient presented with a primary Ewing's sarcoma of the skull, involving the dura of the frontal and parietal lobes of the left cerebral hemisphere. He was treated with gross total surgical excision of tumor, skull reconstruction, chemotherapy, and irradiation. Twelve years after the surgery, the patient has no evidence of local recurrence or distant metastases. Radical surgical excision of the primary tumor with safety margins is thought to play a role in the favorable clinical course.

 The presented case is the longest surviving patient after treatment of primary Ewing's sarcoma of the skull bone. This rare type of tumor may allow better survival rates under adequate management than sarcoma elsewhere in the body.

Development and testing of anti-SARS-CoV-2 drugs or vaccines have not turned to be realistic within the timeframe needed to combat this pandemic. Here, we report a comprehensive computational approach to identify the multi-targeted drug molecules against the SARS-CoV-2 proteins, whichare crucially involved in the viral-host interaction, replication of the virus inside the host, disease progression and transmission of coronavirus infection. Virtual screening of 75 FDA-approved potential antiviral drugs against the target proteins, spike (S) glycoprotein, human angiotensin-converting enzyme 2 (hACE2), 3-chymotrypsin-like cysteine protease (3CLpro), cathepsin L (CTSL), nucleocapsid protein, RNA-dependent RNA polymerase (RdRp) and non-structural protein 6 (NSP6), resulted in the selection of seven drugs which preferentially bind to the target proteins. Further, the molecular interactions determined by molecular dynamics simulation revealed that among the 75 drug molecules, catechin can effectively bind to 3CLpro, CTSL, RBD of S protein, NSP6 and nucleocapsid protein. It is more conveniently involved in key molecular interactions, showing binding free energy (ΔGbind) in the range of -5.09 kcal/mol (CTSL) to -26.09 kcal/mol (NSP6). At the binding pocket, catechin is majorly stabilized by the hydrophobic interactions, displays ΔEvdW values -7.59 to -37.39 kcal/mol. Thus, the structural insights of better binding affinity and favorable molecular interaction of catechin toward multiple target proteins signify that catechin can be potentially explored as a multi-targeted agent against COVID-19.
As chemotherapy and radiotherapy have developed, the role of a neurosurgeon in the treatment of metastatic brain tumors is gradually changing. Real-time intraoperative visualization of brain tumors by near-infrared spectroscopy (NIRS) is feasible. The authors aimed to perform real-time intraoperative visualization of the metastatic tumor in brain surgery using second-window indocyanine green (SWIG) with microscope and exoscope systems.

Ten patients with intraparenchymal brain metastatic tumors were administered 5 mg/kg indocyanine green (ICG) 1 day before the surgery. In some patients, a microscope was used to help identify the metastases, whereas in the others, an exoscope was used.

NIRS with the exoscope and microscope revealed the tumor location from the brain surface and the tumor itself in all 10 patients. Capivasertib datasheet The NIR signal could be detected though the normal brain parenchyma up to 20 mm. While the mean signal-to-background ratio (SBR) from the brain surface was 1.82 ± 1.30, it was 3.35 ± 1.76 from the tumor.
