Implementing a nurse-led prehabilitation program for patients undergoing spinal surgery.

ABSTRACT: Prehabilitation, or "prehab," helps patients optimize strength, function, and nutrition before surgery. This evidence-based practice project presents strategies for implementing a prehab program to prepare patients for spinal surgery. Nurses play an integral role in educating patients preoperatively about the myriad lifestyle changes associated with spinal surgery.

Frameless image-guided linear accelerator (LINAC) stereotactic radiosurgery for medically refractory trigeminal neuralgia: Clinical outcomes in 116 patients.

Background: Frameless image-guided radiosurgery (IGRS) is an effective and non-invasive method of treating patients who are unresponsive to medical management for trigeminal neuralgia (TN). This study evaluated the use of frameless IGRS to treat patients with medically refractory TN. Methods: We performed a retrospective review of records of 116 patients diagnosed with TN who underwent frameless IGRS using a linear accelerator (LINAC) over 10 years (March 2012-February 2023). All patients had failed medical management for TN. Facial pain was graded using the Barrow Neurological Institute (BNI) scoring system. Each patient received a BNI score before frameless IGRS and following treatment. Failure was defined as a BNI score IV-V at the last follow-up and/or undergoing a salvage procedure following IGRS. Results: All patients had a BNI score of either IV or V before the frameless IGRS. The mean follow-up duration for all 116 patients following IGRS was 44.1 months. Most patients (81 [69.8%]) had not undergone surgery (microvascular decompression [MVD] or rhizotomy) or stereotactic radiosurgery (SRS) for TN before frameless IGRS. A total of 41 (35.3%) patients underwent a salvage procedure (MVD, rhizotomy, or an additional IGRS) following frameless IGRS. The mean duration between the initial frameless IGRS and salvage procedure was 20.1 months. At the last follow-up, a total of 110 (94.8%) patients had a BNI score of I-III. No complications were reported after the frameless IGRS. The BNI score at the last follow-up was lower compared to the initial BNI for patients regardless of prior intervention (P < 0.001). Patients who failed IGRS had a higher BNI score at the last follow-up compared to those who did not fail IGRS (2.8 vs. 2.5, P = 0.05). Patients with pain relief had a shorter follow-up compared to those with pain refractory to SRS (38.0 vs. 55.1, P = 0.005). Conclusion: In this large cohort of patients with medically refractory TN, frameless IGRS resulted in durable pain control in the majority of patients without any toxicity.

Genomic characterization of vulvar squamous cell carcinoma reveals differential gene expression based on clinical outcome.

OBJECTIVE: The greatest challenge in the management of vulvar squamous cell carcinoma (VSCC) is treatment of recurrent disease where options for surgery and radiation have been exhausted, or treatment of disease where distant metastasis is present. Identification of mutations differentially expressed between tumor from patients who died of aggressive disease and tumor from patients with an indolent course could reveal novel prognostic indicators and guide development of therapeutic drugs. METHODS: From 202 consecutive patients with VSCC, patients who recurred and died of disease (group A) were identified and matched by age, tumor size, depth of invasion and nodal status with those whose disease did not recur (group B). Tumors from 21 patients were subjected to whole exome sequencing of DNA and RNA, immunohistochemistry (IHC) antibodies of PD-L1 and P16, and in-situ hybridization (ISH) for high-risk HPV. RESULTS: Analysis of DNA and RNA revealed six genes that were strongly differentially expressed between group A and B: TGM3, ACVR2A, ROS1, NFEL2, CCND1 and BCL6. Clinically relevant DNA mutations were significantly greater in group A versus B: 7 vs 2.3 mutations per patient. The most common genomic alterations were mutations in TP53 and the promoter region of TERT. Other common genomic events include alterations of FAT1, CDKN2A, PIK3CA, CCND1, and LRP1B. All samples were MSI stable and tumor mutational burden (TMB) was similar in groups A and B. Most VSCC specimens (81%) were positive for PD-L1. CONCLUSIONS: ACVR2A and TGM3 are significantly under-expressed in tumors with poor outcome, suggesting they may play a role in tumor suppression. Clinical outcome of VSCC appears independent of MSI, TMB, or PD-L1 status.

Impact of Occupations and Hobbies on the Severity of Carpal Tunnel Syndrome: An Electrodiagnostic Perspective.

OBJECTIVE: This study describes the clinical and electrodiagnostic (EDX) findings as well as occupations and hobbies in 613 patients diagnosed with carpal tunnel syndrome (CTS). METHODS: Patients with moderate, moderately severe, or severe CTS based on EDX criteria were included. RESULTS: The most common occupations included workers in offices, construction/maintenance, and assembly lines. The occupation severity scores were greatest in garment workers, musicians, and landscapers. Regardless of occupation, patient age and occupation duration were significantly correlated ( P < 0.001). Gardeners had the highest average severity score of the hobbies, followed by painters, those who sew, and individuals who perform house chores. CONCLUSIONS: Physicians should be aware of particular occupations and hobbies associated with a greater risk of severe CTS and offer modifications to their patients' work duties and hobbies to minimize the likelihood of developing severe CTS.

Etiology of spastic foot drop among 16 patients undergoing electrodiagnostic studies: patient series.

BACKGROUND: Differentiating foot drop due to upper motor neuron (UMN) lesions from that due to lower motor neuron lesions is crucial to avoid unnecessary surgery or surgery at the wrong location. Electrodiagnostic (EDX) studies are useful in evaluating patients with spastic foot drop (SFD). OBSERVATIONS: Among 16 patients with SFD, the cause was cervical myelopathy in 5 patients (31%), cerebrovascular accident in 3 (18%), hereditary spastic paraplegia in 2 (12%), multiple sclerosis in 2 (12%), chronic cerebral small vessel disease in 2 (12%), intracranial meningioma in 1 (6%), and diffuse brain injury in 1 (6%). Twelve patients (75%) had weakness of a single leg, whereas 2 others (12%) had bilateral weakness. Eleven patients (69%) had difficulty walking. The deep tendon reflexes of the legs were hyperactive in 15 patients (94%), with an extensor plantar response in 9 patients (56%). Twelve patients (75%) had normal motor and sensory conduction, 11 of whom had no denervation changes of the legs. LESSONS: This study is intended to raise awareness among surgeons about the clinical features of SFD. EDX studies are valuable in ruling out peripheral causes of foot drop, which encourages diagnostic investigation into a UMN source for the foot drop.

Etiological study of superficial radial nerve neuropathy: series of 34 patients.

Objectives: Superficial radial nerve (SRN) neuropathy is a rare focal neuropathy leading to pain and paresthesia of the dorsolateral aspect of the hand. Reported causes include trauma, extrinsic compression, or it may be idiopathic. We describe the clinical and electrodiagnostic (EDX) features of 34 patients with SRN neuropathy of varied etiology. Methods: This is a retrospective study of patients with upper limb neuropathy referred for EDX studies who were found to have SRN neuropathy based on clinical and EDX findings. Twelve patients also had ultrasound (US) evaluations. Results: Decreased pinprick sensation was noted in the distribution of the SRN in 31 (91%) patients, and a positive Tinel's sign was observed in 9 (26%). Sensory nerve action potentials (SNAPs) were not recordable in 11 (32%) patients. Of the patients who had a recordable SNAP, the latency was delayed, and the amplitude was decreased in all cases. Of the 12 patients who underwent US studies, 6 (50%) had an increased cross-sectional area of the SRN at or immediately proximal to the site of injury/compression. A cyst was located adjacent to the SRN in 2 patients. The most common cause of SRN neuropathy was trauma in 19 (56%) patients, of which 15 were iatrogenic. A compressive etiology was identified in 6 patients (18%). No specific etiology was detected in 10 patients (29%). Conclusion: This study is aimed at raising the awareness among surgeons about the clinical features and varied causes of SRN neuropathy; such knowledge may potentially lessen iatrogenic causes of injury.

Impact of Dyslexia and Health Literacy on Racial and Gender Disparity in the Incarcerated Population.

Dyslexia is the most common learning disability and involves difficulty in reading, writing, and spelling in your native language despite at least average intelligence. A disproportionate share of incarcerated individuals have both dyslexia and are African American. Behavior manifestations associated with dyslexia often lead to life choices resulting in incarceration. Dyslexia is rarely considered as playing a role in unemployment, drug misuse, and incarceration. Dyslexia screening upon prison admission permits identification of individuals with dyslexia and allows for specialized reading classes to boost self-esteem and develop a skill set that is desirable in the workforce upon release. Dyslexia should be recognized as a social determinant of health whose early recognition and intervention may engender self-confidence in those affected and encourage them to be positively engaged in society.

Iatrogenic median and ulnar nerve injuries during carpal tunnel release: clinical, electrodiagnostic, and ultrasound features in 12 patients. Patient series.

BACKGROUND: Nerve injuries during carpal tunnel release (CTR) are rare. Electrodiagnostic (EDX) and ultrasound (US) studies may be helpful in evaluating iatrogenic nerve injuries during CTR. OBSERVATIONS: Nine patients sustained a median nerve injury, and 3 patients experienced ulnar nerve damage. Decreased sensation occurred in 11 patients, and dysesthesia occurred in 1 patient. Abductor pollicis brevis (APB) weakness occurred in all patients with median nerve injury. Of the 9 patients with median nerve injury, the compound muscle action potentials (CMAPs) of the APB and sensory nerve action potentials (SNAPs) of the 2nd or 3rd digit were not recordable in 6 and 5 patients, respectively. Of the 3 patients sustaining ulnar nerve injuries, the CMAPs of the abductor digiti minimi (ADM) and SNAPs of the 5th digit were not recordable in 1 patient; 2 patients showed prolonged latency and decreased amplitude of CMAPs/SNAPs. US studies of 8 patients with a median nerve injury showed a neuroma within the carpal tunnel. One patient underwent surgical repair urgently, and 6 did so after variable intervals. LESSONS: Surgeons should be cognizant of nerve injuries during CTR. EDX and US studies are useful in evaluating iatrogenic nerve injuries during CTR.

Using a Harm Reduction Approach to Treat Inpatients With Substance Use Disorders.

OBJECTIVE: This study investigated harm reduction (HR) strategies at our institution to decrease the number of patients with a substance use disorder (SUD) who left against medical advice (AMA). BACKGROUND: HR is a public health strategy used for adult substance use problems for whom abstinence is not feasible. METHODS: An HR program was established at 1 institution to enhance the care of hospitalized patients with a SUD. RESULTS: Of the 1780 unique visits for patients with a diagnosis of SUD, 311 patients (17.5%) left our hospital AMA or eloped. The average length of stay for all patients evaluated by the HR team was 6.6 days compared with 4.0 days for those who left AMA. Patients with >1 hospital stay accounted for 22% of our population but represented 34% of the patients who left AMA. CONCLUSIONS: This study reports the approaches implemented to reduce the AMA rate of patients with a SUD and to promote patient-enhanced care.

Surgical Technologist Apprentice Program: An Innovative Approach to Improve Staffing.

Along with surgeons, anesthesia professionals, and RN circulators, surgical technologists are essential members of the perioperative team. Despite a partnership with a local community college that offered a surgical technologist degree program, Norton Healthcare in Louisville, Kentucky, continued to experience a shortage of surgical technologists. To meet demands, the clinical educators at the facility developed an in-house Surgical Technologist Apprentice Program (STAP). The STAP consists of six weeks of didactic learning and hands-on training in an OR simulation laboratory, followed by a six-month preceptorship in the OR. This program has proven invaluable, particularly as the COVID-19 pandemic increased the need for personnel who are not only skilled in the OR but also can provide essential frontline patient care when needed. Together, the STAP and the college partnership offer a career-building opportunity for those in entry-level positions who may not otherwise be able to afford to train for this specialized role.

Differences in Clinical Characteristics Between Prepubescent and Postpubescent Males With Testicular Torsion.

Testicular torsion represents a pediatric surgical emergency. In this 6-year study with 140 patients, prepubescent (<13 years) and postpubescent (≥13 years) males with testicular torsion were identified. Prepubescent boys had a longer symptom duration (P = .016) and underwent more orchiectomies (P = .005) compared with postpubescent boys. The risk of orchiectomy decreased by 15% per 1-year increase in age (P = .002). Boys who underwent an orchiectomy had a longer symptom duration (P < .001), were younger (P = .002), had scrotal swelling (P = .001), scrotal erythema (P < .001), higher degrees of torsion (P = .036), and more left-sided surgeries (P = .014) compared with those who had an orchiopexy. Postpubescent boys were 63% less likely to receive an orchiectomy versus an orchiopexy compared with prepubescent boys. Pediatricians should be cognizant of the age discrepancies between prepubescent and postpubescent males with testicular torsion and educate parents about the importance of urgent evaluation in the Emergency Department to reduce the likelihood of an orchiectomy.

Gunshot-related nerve injuries of the upper extremities: clinical, electromyographic, and ultrasound features in 22 patients.

Objectives: Gunshot wounds of the upper extremities may cause permanent neurovascular injuries, leading to significant morbidity, chronic pain, functional loss, and disability. While there are many reports on the incidence and intraoperative findings in gunshot-related nerve injuries (GSNI) sustained during wars, there is a paucity of details pertaining to GSNI of the upper extremities in civilians. The goal of this paper is to provide the clinical, electrodiagnostic (EDX), and ultrasound (US) findings in 22 patients with GSNI of the upper extremities. Methods: This is a retrospective study of patients referred for EDX studies to evaluate the presence of nerve injury after sustaining GSWs to the upper extremities. All patients underwent EDX studies, and 16 patients had US evaluations. Numerous metrics were documented including presenting symptoms, neurological abnormalities, EDX findings, and US features. Results: The forearm was the most frequent location of injury (8 [36%] patients). The ulnar nerve was the most common injured nerve (10 [45%] patients), followed by the brachial plexus (7 [32%] patients). All patients complained of muscle weakness; the most frequently affected muscles were the first dorsal interosseous (FDI) (14 [64%] patients) and abductor pollicis brevis (APB) (11 [50%] patients). Muscle atrophy was noted in 19 (86%) patients, 15 of whom had atrophy of the FDI. Axonotmesis was the type of nerve injury in all patients based on EDX studies. Of the 16 patients who underwent US studies, a neuroma in continuity was noted in 4 (25%) patients and neurotmesis in 1 (6.2%) patient. Eleven (69%) patients had enlarged and/or hypoechoic nerves. Conclusions: Axonotmesis of the ulnar nerve was the most common finding among patients sustaining gunshot injuries to the upper extremities. EDX and US studies provide valuable insight into the underlying pathophysiology and guidance for management of patients with GSNI of the upper extremities.

Role of electromyography and ultrasonography in the diagnosis of double crush lumbar radiculopathy and common fibular injury: illustrative cases.

BACKGROUND: Double crush syndrome consists of two compression sites along a peripheral nerve and is rare in the lower extremities. Electrodiagnostic and ultrasound (US) studies may be helpful in evaluating foot drop involving overlapping pathologies. OBSERVATIONS: Case 1 involved a man who presented with left dorsiflexor weakness and left foot numbness. Electromyography (EMG) revealed a left common fibular nerve entrapment neuropathy and left L5 radiculopathy. US and magnetic resonance imaging (MRI) revealed a large cystic lesion of the left common fibular nerve treated by cyst removal. The left foot drop persisted postoperatively. Lumbar computed tomography myelography revealed severe left foraminal stenosis at L5-S1. Multilevel lumbar laminectomies and facetectomies with an L5-S1 fusion were performed. Within 1 month postoperatively, the left foot drop had improved. Case 2 involved a man who developed a right foot drop caused by right lumbar foraminal stenosis at L4-5 and L5-S1. EMG and US of the right common fibular neuropathy showed large fascicles involving the right common fibular nerve. MRI revealed a hyperintense signal of the right common fibular nerve. Spontaneous improvement occurred within 6 months without surgery. LESSONS: Spine surgeons should recognize double crush in the lower extremities. EMG and US are valuable in detecting peripheral nerve abnormalities, especially in cases with overlapping lumbar pathology.

Caring for behaviorally challenging patients in nonpsychiatric settings.

ABSTRACT: This article discusses a pilot study on the use of a behavior support plan to safely address patients who exhibit disruptive behaviors in the ED and nonpsychiatric medical settings while respecting their autonomy.

Multifocal intradural extramedullary ependymoma, MYCN amplified: illustrative case.

BACKGROUND: Ependymomas are the most frequent tumors of the adult spinal cord, representing 1.9% of all central nervous system tumors and 60% of spinal cord tumors. Spinal ependymomas are usually solitary, intramedullary lesions. While intradural extramedullary (IDEM) ependymomas are infrequent, multifocal IDEM ependymomas are exceptionally rare. OBSERVATIONS: The authors reported the first case in the literature of a patient diagnosed with multifocal IDEM ependymomas who was treated with tumor resection and brain and spinal radiotherapy. The patient presented with a 10-day history of bilateral leg numbness extending to the umbilicus and gait instability. Magnetic resonance imaging (MRI) studies revealed multiple enhancing nodular nodules throughout the entire spinal canal. Brain MRI revealed no abnormal lesions. A World Health Organization grade II ependymoma was confirmed histologically. At 31 months postoperatively, the patient remained clinically asymptomatic. Although cervical and thoracic MRI revealed stable intradural nodules and several areas of leptomeningeal enhancement, no malignant cells were seen in the cerebrospinal fluid (CSF). He underwent genetic testing to determine the appropriate chemotherapeutic agent if activation of the tumor should arise. LESSONS: Because complete resection of multifocal IDEM ependymomas is not feasible, continued monitoring with brain and spine MRI is warranted to detect potential tumor dissemination in the CSF.

Nerve Ultrasound Findings before and after Surgery in a Patient with Charcot-Marie-Tooth Disease Type 1A and Comorbid Carpal Tunnel Syndrome.

The diagnosis of comorbid carpal tunnel syndrome (CTS) in patients with Charcot-Marie-Tooth (CMT) disease is challenging due to the overlapping symptoms and inconclusive electrodiagnostic studies (EDX). This case report is aimed at illustrating the value of ultrasonography (US) in a patient with CMT1 disease and comorbid CTS. A 28-year-old woman presented with symptoms of painful paresthesia and weakness of both hands. EDX demonstrated a demyelinating sensory-motor polyneuropathy in the upper and lower extremities, consistent with CMT1 disease. US showed an increased cross-sectional area (CSA) of the median nerve at the carpal tunnel inlet (CTI) with a significant drop in the diameter within the carpal tunnel, confirming concurrent CTS. Genetic testing confirmed PMP22 duplication consistent with CMT1A. Bilateral carpal tunnel releases were performed with partial symptom resolution within 3 weeks. Postoperative EDX demonstrated improved motor conduction across the wrist, but the sensory potentials continued to be unrecordable. US showed a significant reversal of the diameter-drop of the median nerve within the carpal tunnel and decrease in CSA at the CTI. US imaging is a valuable technique for identifying comorbid CTS in patients with CMT and directing appropriate treatment.

Single low-dose targeted bevacizumab infusion in adult patients with steroid-refractory radiation necrosis of the brain: a phase II open-label prospective clinical trial.

OBJECTIVE: There is an unmet need for safe and rapidly effective therapies for refractory brain radiation necrosis (RN). The aim of this prospective single-arm phase II trial was to evaluate the safety and efficacy of a single low-dose targeted bevacizumab infusion after blood-brain barrier disruption (BBBD) in adult patients with steroid-refractory brain RN. METHODS: Ten adults with steroid-refractory, imaging-confirmed brain RN were enrolled between November 2016 and January 2018 and followed for 12 months after treatment. Bevacizumab 2.5 mg/kg was administered as a one-time targeted intra-arterial infusion immediately after BBBD. Primary outcomes included safety and > 25% decrease in lesion volume. Images were analyzed by a board-certified neuroradiologist blinded to pretrial diagnosis and treatment status. Secondary outcomes included changes in headache, steroid use, and functional status and absence of neurocognitive sequelae. Comparisons were analyzed using the Fisher exact test, Mann-Whitney U-test, linear mixed models, Wilcoxon signed-rank test, and repeated-measures 1-way ANOVA. RESULTS: Ten adults (mean ± SD [range] age 35 ± 15 [22-62] years) participated in this study. No patients died or exhibited serious adverse effects of systemic bevacizumab. At 3 months, 80% (95% CI 44%-98%) and 90% (95% CI 56%-100%) of patients demonstrated > 25% decrease in RN and vasogenic edema volume, respectively. At 12 months, RN volume decreased by 74% (median [range] 76% [53%-96%], p = 0.012), edema volume decreased by 50% (median [range] 70% [-11% to 83%], p = 0.086), and headache decreased by 84% (median [range] 92% [58%-100%], p = 0.022) among the 8 patients without RN recurrence. Only 1 (10%) patient was steroid dependent at the end of the trial. Scores on 12 of 16 (75%) neurocognitive indices increased, thereby supporting a pattern of cerebral white matter recovery. Two (20%) patients exhibited RN recurrence that required further treatment at 10 and 11 months, respectively, after bevacizumab infusion. CONCLUSIONS: For the first time, to the authors' knowledge, the authors demonstrated that a single low-dose targeted bevacizumab infusion resulted in durable clinical and imaging improvements in 80% of patients at 12 months after treatment without adverse events attributed to bevacizumab alone. These findings highlight that targeted bevacizumab may be an efficient one-time treatment for adults with brain RN. Further confirmation with a randomized controlled trial is needed to compare the intra-arterial approach with the conventional multicycle intravenous regimen. Clinical trial registration no.: NCT02819479 (ClinicalTrials.gov).

Leadership Immersion and Aspiring Leader Programs Designed to Improve Nurses' Well-Being and Competence: Integral Features During the COVID-19 Pandemic.

Nurse leaders play integral roles in the health care system as they focus on patient quality of care and safety at a high level and lead teams of frontline staff. Nurse leadership turnover during COVID-19 poses challenges not only for continuity of patient care but also for organizations that may fail to meet their specific goals. When a nurse leader role is not filled, gaps in care delivery occur. Our institution developed the Leadership Immersion and Aspiring Leader Programs prior to COVID-19 that provide application to theory opportunities to new nursing leaders who are prepared to fill leadership positions.

Parsonage-Turner Syndrome Following COVID-19 Vaccination: Clinical and Electromyographic Findings in 6 Patients.

Parsonage-Turner syndrome (PTS) following COVID-19 infection or vaccination is rare. The pathophysiology may involve an immune-mediated inflammatory reaction against brachial plexus nerve fibers in a genetically predisposed individual. We describe the clinical and electromyographic features of 6 patients presenting with the clinical picture of PTS following COVID-19 vaccination. All patients were referred for electromyographic studies to evaluate the acute onset of pain in the shoulder girdle/upper limb accompanied by muscle weakness in the distribution of one or more branches of the brachial plexus. Each patient had received the COVID-19 vaccine within a few weeks prior to the onset of symptoms. Patients underwent detailed neurological examinations followed by nerve conduction and EMG studies. The patients developed symptoms after a mean duration of 17 days (5 days-8 weeks) after receiving the COVID-19 vaccine. The initial symptom was pain in the shoulder girdle/upper limb, followed within days by muscle weakness. Physical examinations and EMG studies showed upper trunk brachial plexopathy in 2 patients, lower trunk plexopathy in 1 patient, posterior cord brachial plexopathy in 1 patient, and anterior/posterior interosseous nerve involvement in 2 patients. All patients either improved or attained complete resolution of the arm pain at follow-up. Three (50%) patients did not have any improvement in the arm/hand weakness, while 3 (50%) patients had some recovery in strength. PTS may occur after the COVID-19 vaccine and should be suspected in patients with symptoms and signs suggestive of acute brachial plexopathy. Studies of a larger series may provide insight into predisposing factors.
