Treatment with the iNOS inhibitor 1400W or mutation of GAPDH S-nitrosation sites alleviated apoptosis of C2C12 cells, further demonstrating that GAPDH S-nitrosation in aging contributes to sarcopenia. Taken together, these findings reveal a new cellular mechanism underlying age-related sarcopenia, and the demonstration of muscle loss mediated by iNOS-induced GAPDH S-nitrosation suggests a potential therapeutic strategy for sarcopenia.

Despite the fact that bevacizumab (Bev) has been approved to treat recurrent glioblastoma, patients have failed to demonstrate a significant overall survival (OS) advantage. In recent years, the advent of more Bev combination regimens seems to bring new hope for patients; nevertheless, there is still a lack of intuitive comparison among these therapies.

To explore the efficacy and safety of various Bev combination regimens in patients with recurrent glioblastoma and to further explore the differences in the efficacy of each treatment in randomized controlled trials (RCTs) and nonrandomized controlled trials (non-RCTs).

We comprehensively searched the PubMed, Cochrane Library, and OVID databases for relevant RCTs and non-RCTs of Bev in combined regimens for recurrent glioblastoma. The Cochrane quality assessment method was used to assess the quality of RCTs, and the Newcastle-Ottawa scale was used to assess the quality of non-RCTs. Excel software was used to extract data from the literature, and a networubgroup analysis, among RCTs, Bev+ CCNU therapy had the highest 6-month OS and 6-month progression-free survival. Among non-RCTs, Bev+ Iri therapy showed the highest 6-month OS and good 6-month progression-free survival.

Both Bev+ CCNU and Bev+ rindopepimut could be considered as effective therapies for treating the recurrent glioblastoma according to the network meta-analysis results. Among them, Bev+ rindopepimut therapy seems to be safer and more effective. Moreover, we found that Bev+ Iri also appeared to be an effective therapy in a retrospective study.

Posterior cerebral artery (PCA) aneurysms are rare, and most are giant, dissecting, or fusiform in morphology. Proximal occlusion of the PCA without revascularization causes high risk of ischemic complications. This study aimed to evaluate the safety and validity of using superficial temporal artery (STA)-PCA bypass through zygomatic anterior temporal approach in complex PCA aneurysms.

Trapping or resecting of aneurysms and reconstruction of distal PCA through a zygomatic anterior temporal approach were performed in 6 patients from June 2017 to August 2020. Postoperative angiography confirmed obliteration of aneurysms and patency of bypass artery. Neurological function was assessed by the modified Rankin Scale (mRS).

Patients were 4 men and 2 women with a mean age of 43.8 years (range, 21-58 years). Subarachnoid hemorrhage occurred in 5 patients. Hunt and Hess grade was IV in 3 patients, III in 2 patients, and I in 1 patient. All PCA aneurysms were treated with trapping or resection of the aneurysms andve field exposure and reduces retraction of temporal lobe.

To determine factors associated with anxiety and depression among neurosurgeons after vaccination during the coronavirus disease 2019 (COVID-19) pandemic.

An online survey was completed by neurosurgeons worldwide over 4 weeks. Depression in neurosurgeons was assessed by the 20-item self-reporting questionnaire.

A total of 534 responses were received and analyzed. Almost half of the respondents were from Asia (50.9%), followed by Europe (38.8%). The majority of the respondents were <40 years old (88%), and almost two thirds were trainees (62.2%). Half of the respondents worked in departments with <40 beds (50.7%), and the majority were practicing in the private sector (72.5%). Most of the respondents (85.8%) had COVID-19-positive colleagues in their department, and 64% had exposure to a COVID-19-positive colleague, family member, and/or patient. More than half of the respondents were exposed to infected patients and/or colleagues, and almost half (43.1%) underwent COVID-19 testing when exposed. Neang people who were not vaccinated.

The goal of this study was to examine neurosurgical scientific publications and change in the trends in major neurosurgical journals during the last 10 years.

The peer-reviewed articles published in 12 prominent neurosurgical journals over the last 10 years were analyzed. The journals were grouped into 2 groups based on the number of articles published in a journal in a year (≥500 or <500).

The total number of peer-reviewed articles published in 10 years in these 12 journals was 48,957. The number of peer-reviewed articles published in a year increased from 3441 to 7316 over this time. The maximum number of peer-reviewed articles were published in 2019 in Group A (n= 7170) and in 2018 in Group B journals (n= 615). The commonest article types were Original Articles and Case Reports in both the groups, but the proportion of Original Articles published was greater in Group A journals (54.0%) as compared with Group B journals (44.5%). Review Articles were more commonly published in Group B journals. The proportion of articles published in Group A and B journals from the United States was 48.0% and 31.7%, respectively, whereas the proportion of articles from Europe was 21.4% and 36.2%, respectively.

Several microsurgical techniques are available for the decompression of lumbar spinal stenosis (LSS). More recently, a spinous process-splitting laminectomy (SPSL) technique was introduced, with the premise of diminishing paraspinal muscle damage. This study aims to compare the neurologic and functional outcomes, as well as the differences in early postoperative pain and analgesic use during hospitalization after conventional decompression (CD) versus SPSL surgery for LSS.

Single-center retrospective analysis of all spinal decompression procedures (CD or SPSL) that were performed or supervised by one consulting spine surgeon, performed for LSS between 2015 and 2020. Preoperative neurologic symptoms, functional outcomes, as well as perioperative analgesic use and reported pain scales during hospitalization were analyzed.

From a total of 106 patients, 58 were treated using CD and 48 using SPSL. In both groups, around one-third of the patients were taking opiates preoperatively (38% for CD, 31% for SPSL). equal amounts or fewer analgesics postoperatively.

Anterior cervical discectomy and fusion (ACDF) has been considered the standard treatment for degenerative cervical disc disease; however, recent trials have shown comparable outcomes with cervical disc arthroplasty (CDA). This study aimed to observe disparities in treatment paradigms of single-level cervical disc diseases and compare inpatient outcomes between procedures.

A retrospective cohort of patients treated for single-level cervical disc herniation or degeneration without myelopathy was queried from the Nationwide Inpatient Sample spanning 2012-2015. Multivariate logistic regression was performed to assess the effects of demographics, temporality of admission, and hospital characteristics on odds of receiving CDA versus ACDF. Propensity-score matching was performed to compare cost, length of stay (LOS), non-home discharge, and inpatient complications.

In total, 1028 CDAs and 44,374 ACDFs were performed for single-level cervical disc disease during 2012-2015. Matched comparison showed that while ive CDA.

Subarachnoid hemorrhage (SAH) is a rare complication secondary to cerebrospinal fluid (CSF) leakage during spinal surgery, but the specific cause of bleeding is still unclear. In this retrospective single-center study, we studied cases of acute SAH after spinal surgery to identify the related risk factors for bleeding.

A total of 441 patients with CSF leakage who underwent spinal surgery from 2011 to 2020 were retrospectively analyzed. According to whether postoperative SAH occurred, the patients were divided into the SAH group and the control group. By comparing the demographic data, past history, imaging data, intraoperative findings, perioperative complications, and treatment conditions in the 2 groups to identify the risk factors for SAH, we aimed to provide guidance for the prevention of SAH after spinal surgery.

In our study, the incidence of CSF during spinal surgery is 3.04%, and the rate for SAH associated with spine operation is 0.16%. In the SAH group, 17 patients (73.9%) had preoperative hypIn addition, hypertension was a factor related to SAH during spinal surgery.Arachnoid cysts are one of the benign spinal cystic lesions. Multiple nerve roots and spinal cord may be compressed by it, and operating is often recommended. Traditional surgical procedures often choose the posterior median approach, separating the paravertebral muscles, milling the lamina, fully exposing the cyst, partially or completely removing the cyst wall, looking for the leak, and then suturing and sealing. Here we present a case of giant spinal extradural arachnoid cyst in which a ultrafine flexible endoscope was used to visualize cystic spaces and identity the leaks. We repaired the leak after removing part of the cyst wall under the operating microscope, and the patient had an excellent recovery.

Manual vacuum aspiration is a safe surgical option for the management of early pregnancy loss. To provide rapid, patient-centred access to MVA, an Outpatient Program for Early pregnancy Loss ("OPEL") was established at our institution. Objectives were to (1) assess complete uterine evacuation rates; (2) assess complication rates, and (3) assess patient satisfaction with the program.

With REB approval, a retrospective study was performed. Patient records from the first 18 months of OPEL (November 2015 to April 2017) were reviewed. Anonymous patient satisfaction questionnaires were completed immediately post-procedure.

A total of 162 patients received treatment. Missed abortions accounted for 94 cases (58%). Median delay from referral to clinic appointment was 4.0 (interquartile range [IQR] 2.0-6.0) days. Average length of stay was 3.0 (IQR 2.5-3.0) hours. Efficacy of the procedure was 95.1%. Complication rate (immediate and delayed) was 14.2% and included intraoperative hemorrhage (3.1%; 5/162), Asherman's syndrome (1.9%; 3/162), retained products of conception requiring further treatment (4.9%; 8/162), and postoperative infection requiring antibiotic therapy (1.9%; 3/162). A total of 151 post-procedure satisfaction surveys were completed (93%); 100% agreed/strongly agreed that the nursing staff and physicians provided professional and compassionate care; 99.3% were satisfied with their care overall. Qualitative feedback was positive.

Pregnant patients experiencing early pregnancy loss benefit from safe, timely, accessible, patient-centred care in the outpatient OPEL program. Similar models should be adopted nationally to ensure women experiencing this common pregnancy complication receive safe and compassionate care.
