Intraoperative neurophysiological monitoring (IONM) is shown to be useful in surgeries when the nervous system is at risk. Its success in part relies upon proper setup of often dozens of electrodes correctly placed and secured upon patients and inserted in specific stimulating and recording receptacles. Given the complicated setups and the demanding operating room environment, errors in setup are bound to occur. These have led to false negatives associated with new patient morbidities including, at times, paralysis. No studies quantify the prevalence of these types of setup errors. Approximately 800,000 operations annually utilize intraoperative neuromonitoring in the US alone, so even a small percentage of errors suggests clinical significance. In addition, these types of errors hinder the overall effectiveness of IONM and may result in lower reported sensitivities and lower cost-effectiveness of this important service. We sought to discover through a prospective study and verification through chart review the prevalence of "electrode-swap" errors (when recording and/or stimulating electrodes are incorrectly placed on the patient or in the IONM equipment during setup) across all procedures monitored. We found recording and/or stimulating electrode set up errors in 24 of 454 cases (5.3%). These data and examples of how errors were discovered intraoperatively are reported. We also offer techniques to help reduce this error rate. This study demonstrates a significant potential avoidable error in IONM diagnostic utility, patient outcome, and sensitivity/specificity of alert criteria. The value of identifying and correcting these errors is consequential, multifaceted, and far-reaching.

BACKGROUND
Spinal cord injury (SCI) is a consequence of significant disability and health issues globally, and long COVID represents the symptoms of neuro-musculoskeletal, cardiovascular and respiratory complications.
PURPOSE
This study aimed to identify the symptom responses and disease burden of long COVID in individuals with spinal cord injury.
METHODS
This case-control study was conducted on patients with SCI residing at a specialised rehabilitation centre in Bangladesh. Forty patients with SCI with and without long COVID symptoms (LCS) were enrolled in this study at a 1:1 ratio according to WHO criteria.
RESULT
Twelve LCS were observed in patients with SCI, including fatigue, musculoskeletal pain, memory loss, headache, respiratory problems, anxiety, depression, insomnia, problem in ADL problem in work, palpitation, and weakness. The predictors of developing long COVID include increasing age (p<0.002), increasing BMI (p<0.03), and longer duration of spinal cord injury (p<0.004). A significant difference (p<0.01) in overall years of healthy life lost due to disability (YLD) for non-long COVID cases was 2.04±0.596 compared to long COVID (LC) cases 1.22±2.09 was observed.
CONCLUSION
Bangladeshi patients of SCI presented 12 long COVID symptoms and have a significant disease burden compared to non long COVID cases.

BACKGROUND
Climate anxiety is increasingly prevalent among adolescents worldwide. Are climate-anxious adolescents prone to engage in pro-environmental behavior? Or might the association between climate anxiety and pro-environmental be curvilinear, such that high levels of climate anxiety become 'paralyzing'? And do these associations depend on whether adolescents believe that, with effort, the worst impacts of climate change can still be prevented?
METHODS
We addressed these questions in three studies (two preregistered; combined N = 2,211), conducted across two countries. We used cross-sectional and longitudinal methods, and various measures of climate anxiety and pro-environmental behavior. We performed Bayesian regression analyses comparing two models that tested competing hypotheses. The first model included a linear effect of climate anxiety on pro-environmental behavior, and the second model included both a linear and a curvilinear (i.e. inverted U-shaped) effect of climate anxiety on pro-environmental behavior. Next, we added environmental efficacy to the best fitting model and explored its moderating effects.
RESULTS
Adolescents reported low-to-moderate levels of climate anxiety. Across the board, we found evidence for a small, positive, and mostly linear (rather than curvilinear) association between climate anxiety and pro-environmental behavior. While Study 1 supported a curvilinear association (Bayes Factor (BF) = 18.87), Studies 2 and 3 mostly supported a linear model (BFs range 6.86-12.71), except for weak support (BF = 1.62) for a curvilinear association between climate anxiety symptoms and public sphere pro-environmental behavior. Adolescents' environmental efficacy moderated this link for public sphere (e.g. activism), but not private sphere (e.g. recycling), pro-environmental behavior.
CONCLUSIONS
Climate-anxious adolescents are prone to engage in pro-environmental behavior. We found limited evidence for 'eco-paralysis' (i.e. a passive state of pro-environmental behavioral stasis) at high levels of climate anxiety. Our results are consistent with the possibility that supporting adolescents' environmental efficacy will help climate-anxious adolescents engage in public sphere pro-environmental behavior.

BACKGROUND
Exercise-induced pulmonary hemorrhage (EIPH) is one of the most commonly diagnosed disorders in racehorses. Many EIPH risk factors such as breed, age, high or low environmental temperature, and distance of the race have been studied in racehorses.
AIM
The aim of this study was to study the relationship between EIPH and the presence of jugular vein thrombose in racehorses.
METHODS
Forty-eight thoroughbred racehorses randomly selected from animals with exercise intolerance due to respiratory disorders were enrolled in the present study. Clinical and tracheobronchoscopy examinations were done for EIPH grading. In addition, both jugular veins were examined using ultrasonography for vein thrombosis.
RESULTS
It was noted during endoscopy that many cases suffered from laryngeal paralysis, and we were not able to assess the degree of laryngeal paralysis under sedation. About 40% of horses with exercise intolerance suffered from EIPH of varying degrees. Most cases of jugular vein thrombosis were of the chronic type, as local heat and pain were not observed. About 42% of the exercise-intolerant horses had jugular vein thrombose with most jugular vein thrombosis on the left side. Combined jugular veins thrombose and EIPH were found in about 25% of exercise intolerance horses, while 17% showed jugular vein thrombose without EIPH, and 41% showed no EIPH with the absence of jugular vein thrombose.
CONCLUSION
The present study revealed that jugular vein thrombosis may cause disorders-associated damage to the vessels and anatomical structures close to it, such as the trachea causing EIPH.

Review Comparative Study
INTRODUCTION
Sugammadex, a novel selective antagonist of non-depolarizing neuromuscular blocking agents, has been shown to rapidly and effectively reverse moderate and deep paralysis in adults and pediatric patients over age 2, improving patient recovery and reducing the risk of postoperative complications.
AREAS COVERED
Since the use of sugammadex in patients under age 2 is not widely studied, we aim to provide an overview on the drug's application and potential use in infants and neonates. There is a limited but growing body of evidence for the safe, efficacious use of sugammadex in children under age 2. Relevant studies were identified from the most updated data including case reports, clinical trials, systematic reviews, and meta analyses.
EXPERT OPINION
The results suggest that at a dose of 2 to 4 mg/kg of sugammadex can be safely used to rapidly and effectively reverse neuromuscular blockade in neonates and infants; it is non-inferior based on incidence of adverse events compared to neostigmine. Additionally, sugammadex doses between 8 and 16 mg/kg may be used as a rescue agent for infants during 'can't intubate, can't ventilate' crisis. Overall, sugammadex offers new value in the perioperative care of patients under age 2, with further studies warranted to better understand its application and full effect in the pediatric population.

Effect of ultrasound-guided injection of botulinum toxin type A into shoulder joint cavity on shoulder pain in poststroke patients: study protocol for a randomized controlled trial.
BACKGROUND
Hemiplegic shoulder pain (HSP) is a common complication after stroke. It severely affects the recovery of upper limb motor function. Early shoulder pain in hemiplegic patients is mainly neuropathic caused by central nerve injury or neuroplasticity. Commonly used corticosteroid injections in the shoulder joint can reduce shoulder pain; however, the side effects also include soft tissue degeneration or increased tendon fragility, and the long-term effects remain controversial. Botulinum toxin injections are relatively new and are thought to block the transmission of pain receptors in the shoulder joint cavity and inhibit the production of neuropathogenic substances to reduce neurogenic inflammation. Some studies suggest that the shoulder pain of hemiplegia after stroke is caused by changes in the central system related to shoulder joint pain, and persistent pain may induce the reorganization of the cortical sensory center or motor center. However, there is no conclusive evidence as to whether or not the amelioration of pain by botulinum toxin affects brain function. In previous studies of botulinum toxin versus glucocorticoids (triamcinolone acetonide injection) in the treatment of shoulder pain, there is a lack of observation of differences in changes in brain function. As the content of previous assessments of pain improvement was predominantly subjective, objective quantitative assessment indicators were lacking. Functional near-infrared imaging (fNIRS) can remedy this problem.
METHODS
This study protocol is designed for a double-blind, randomized controlled clinical trial of patients with post-stroke HSP without biceps longus tenosynovitis or acromion bursitis. Seventy-eight patients will be randomly assigned to either the botulinum toxin type A or glucocorticoid group. At baseline, patients in each group will receive shoulder cavity injections of either botulinum toxin or glucocorticoids and will be followed for 1 and 4 weeks. The primary outcome is change in shoulder pain on the visual analog scale (VAS). The secondary outcome is the assessment of changes in oxyhemoglobin levels in the corresponding brain regions by fNIRS imaging, shoulder flexion, external rotation range of motion, upper extremity Fugl-Meyer, and modified Ashworth score.
DISCUSSION
Ultrasound-guided botulinum toxin type A shoulder joint cavity injections may provide evidence of pain improvement in patients with HSP. The results of this trial are also help to analyze the correlation between changes in shoulder pain and changes in cerebral hemodynamics and shoulder joint motor function.

BACKGROUND
The incidence of cervical spinal brucellosis is low, only a few case reports have been published, and case series are not widely reported in the medical literature. Therefore, clinical features, management, and outcomes of cervical spinal brucellosis are relatively unknown. In this series, the authors report 15 cases of patients with cervical spinal brucellosis, including clinical characteristic, imaging findings, management plans, the institution's experience, and outcomes at 1 year postoperatively.
METHODS
The study reviewed the clinical and radiographic records of 15 patients who received antimicrobial pharmacotherapy, and anterior cervical debridement and fusion for cervical spinal brucellosis. The data collected included patient demographic characteristics, spinal level affected, abscess, neurology, pathological reports, duration and type of antimicrobial regimens, details of orthopedic management, and complications incurred during the procedure.
RESULTS
Neck pain (100%) and limb paralysis (86.7%) were the most common clinical presentations, and the disease had a rapid progression. The C6-7 segment was the most commonly affected segment, followed by C4-5 and C5-6. Imaging commonly revealed epidural or paravertebral abscesses (80%). There was a significant improvement in the VAS, JOA, and NDI scores three months after surgery, and the scores continued to improve until the final follow-up. There was a statistically significant difference between the pre- and postoperative scores (P < 0.05). The ESR and CRP levels returned to normal within three months postoperatively, being 7.7 ± 4.5 mm/h and 7.55 ± 3.48 mg/L, respectively. There were statistically significant differences between the pre- and postoperative levels (P < 0.05). The positive rate of bacterial culture testing of pus or lesion tissues was only 40%, but blood cultures revealed an even lower positivity rate (33.3%). The average antimicrobial pharmacotherapy regimen duration was 6.1 ± 1.9 months. All patients achieved intervertebral bone fusion within 8 months (4.8 ± 1.4 months) after surgery and were cured with non-recurrence.
CONCLUSIONS
Spinal brucellosis rarely affects the cervical region, but its impact is more dangerous due to potential complications such as paraplegia or tetraplegia arising from epidural abscesses that compress the spinal cord. Surgical debridement, along with essential antimicrobial therapy, is an effective strategy and can lead to satisfactory prognosis in managing cervical spinal brucellosis.

BACKGROUND
This retrospective study evaluated the outcomes of patients undergoing one-stage resection of VII/VIII schwannomas and hemihypoglossal-facial neurorrhaphy via the translabyrinthine approach (TLA).
METHODS
The study encompassed ten consecutive patients with unilateral hearing loss (six women, four men, mean age: 49.5 ± 12.1 years) who underwent surgery. The cohort included two patients with vestibular schwannomas (VSs), four with facial nerve schwannomas (FNSs) (two originating from the geniculate ganglion of the facial nerve and two from the cerebellopontine angle), one with VS regrowth, and three with residual VSs. Preoperative facial nerve function, assessed using the House-Brackmann (HB) scale, was Grade V in one and Grade VI in nine patients. The mean preoperative duration of facial paralysis was 7.5 ± 6.9 months.
RESULTS
All patients underwent gross total resection. Postoperatively, one patient experienced cerebrospinal fluid leaks, which were successfully managed with lumbar drains and surgical revisions. At follow-up, facial nerve function improved in all patients: HB Grade V to III in one, HB Grade VI to III in one, HB Grade VI to IV in seven, and Grade VI to V in one. No tumor recurrence was observed during the follow-up period (mean duration: 16.6 ± 9.3 months), and no patient had hemilingual atrophy.
CONCLUSION
The TLA for one-stage resection of VII/VIII schwannomas and facial nerve reconstruction is effective in treating both regrowth and residual VSs and FNSs in the cerebellopontine angle or petrosal bone in patients with severe preoperative facial palsy. This technique facilitates simultaneous tumor removal and nerve anastomosis, thereby reducing the need for multiple surgical interventions in patients with hearing loss and compromised facial nerve function.
