Prevalence of depression and anxiety symptoms after stroke in young adults: A systematic review and meta-analysis.

BACKGROUND: Young adults with stroke have distinct professional and social roles making them vulnerable to symptoms of post-stroke depression (PSD) and post-stroke anxiety (PSA). Prior reviews have examined the prevalence of anxiety and depression in stroke populations. However, there are a lack of studies that have focused on these conditions in young adults. OBJECTIVE: We performed a systematic review and meta-analysis of observational studies that reported on symptoms of PSD, PSA and comorbid PSD/PSA in young adults aged 18 to 55 years of age. METHODS: MEDLINE, EMBASE, SCOPUS and PsycINFO were searched for studies reporting the prevalence of symptoms of PSD and/or PSA in young adults with stroke from inception until June 23, 2023. We included studies that evaluated depression and/or anxiety symptoms with screening tools or interviews following ischemic or hemorrhagic stroke. Validated methods were employed to evaluate risk of bias. RESULTS: 4748 patients from twenty eligible studies were included. Among them, 2420 were also evaluated for symptoms of PSA while 847 participants were evaluated for both PSD and PSA symptoms. Sixteen studies were included in the random effects meta-analysis for PSD symptoms, with a pooled prevalence of 31 % (95 % CI 24-38 %). Pooled PSA symptom prevalence was 39 % (95 % CI 30-48 %) and comorbid PSD with PSA symptom prevalence was 25 % (95 % CI 12-39 %). Varying definitions of 'young adult', combinations of stroke subtypes, and methods to assess PSD and PSA contributed to high heterogeneity amongst studies. CONCLUSIONS: We identified high heterogeneity in studies investigating the prevalence of symptoms of PSD and PSA in young adults, emphasizing the importance of standardized approaches in future research to gain insight into the outcomes and prognosis of PSD and PSA symptoms following stroke in young adults. Larger longitudinal epidemiological studies as well as studies on tailored interventions are required to address the mental health needs of this important population. FUNDING: None.

Stroke in Male-to-Female Transgenders: A Systematic Review and Meta-Analysis.

BACKGROUND: The effect of hormonal therapy has been extensively studied in women. However, similar data on male-to-female (MTF) transgenders, another important population that receives hormonal therapy is lacking. Existing studies in MTF transgenders are skewed toward mental health and health-harming behaviors while few have focused on chronic health conditions. Our study aims to review the existing data on stroke in MTF transgenders and perform a quantitative analysis on the frequency of this condition in this special population. METHODS: PubMed, Cochrane, Scopus, Embase, ClinicalTrials.gov, and Web of Science were systematically searched for studies that reported data on the occurrence of cerebrovascular diseases in MTF transgenders. We reported the hormonal regimens, clinical characteristics, and outcomes of stroke in MTF transgenders. A meta-analysis of proportions was performed by the random-effects model to compute for the frequency of cerebrovascular events in MTF transgenders. RESULTS: Fourteen studies were included in the qualitative analysis while five studies were included in the quantitative analysis. A total of 109 MTF transgenders (Mean 14; range 1-53) suffered a cerebrovascular event. Random-effect modeling analysis showed an overall estimated frequency of 2% for cerebrovascular events in transgenders with a moderate degree of heterogeneity (I2 = 62%). CONCLUSION: Hormonal therapy in MTF transgenders may confer cardiovascular risks in this population. However, more population-based studies that include clinical characteristics and outcomes of chronic health diseases in MTF transgenders are warranted. Such studies may be crucial in directing future guidelines on the health care and management of MTF transgenders.

Patient-reported intraoperative experiences during awake craniotomy for brain tumors: a scoping review.

Awake craniotomy (AC) is a neurosurgical procedure that may be used to excise tumors located in eloquent areas of the brain. The techniques and outcomes of AC have been extensively described, but data on patient-reported experiences are not as well known. To determine these, we performed a scoping review of patient-reported intraoperative experiences during awake craniotomy for brain tumor resection. A total of 21 articles describing 534 patients were included in the review. Majority of the studies were performed on adult patients and utilized questionnaires and interviews. Some used additional qualitative methodology such as grounded theory and phenomenology. Most of the evaluation was performed within the first 2 weeks post-operatively. Recollection of the procedure ranged from 0 to 100%, and most memories dealt with the cranial fixation device application, cranial drilling, and intraoperative mapping. All patients reported some degree of pain and discomfort, mainly due to the cranial fixation device and uncomfortable operative position. Most patients were satisfied with their AC experience. They felt that participating in AC gave them a sense of control over their disease and thought that trust in the treatment team and adequate pre-operative preparation were very important. Patients who underwent AC for brain tumor resection had both positive and negative experiences intraoperatively, but overall, majority had a positive perception of and high levels of satisfaction with AC. Successful AC depends not only on a well-conducted intraoperative course, but also on adequate pre-operative information and patient preparation.

A meta-analysis on the prevalence of anxiety and depression in patients with unruptured intracranial aneurysms: exposing critical treatment gaps.

Unruptured intracranial aneurysms (UIAs) are a significant cause of anxiety and depression. Though the annual rupture rate is relatively low, ensuing mortality and morbidity may be high. Most published studies have focused on functional outcomes; however, limited studies have explored and reported on psychiatric outcomes, which are equally important. We aimed to review existing data on anxiety and depression in patients with UIAs. We systematically searched the databases of Pubmed, Cochrane, Scopus, EBSCOHOST, and ClinicalTrials.gov for studies that reported on anxiety and depression in patients with UIAs. Where available, we also reported data on aneurysm characteristics, treatment modalities, and functional outcomes of these populations. We performed a meta-analysis of proportions by random-effects modeling to compute the prevalence of anxiety and depression in patients with UIAs. Eighteen studies reporting a total of 1413 patients with UIAs were included in the systematic review. The mean age was 57.8 (range 27-79); 64% of whom were female. Random-effect modeling analysis showed an overall estimated prevalence of 28% [95% CI: 0.17-0.42] for anxiety and 21% [95% CI: 0.13-0.33] for depression among patients with UIAs. No significant difference was found in the prevalence of these conditions between treated vs untreated aneurysms. Our review highlights the heterogeneity of data from existing studies and the lack of standardized methodologies in determining psychiatric outcomes in patients with UIAs. It was also limited by the small sample sizes and patient counseling bias in the included studies. Larger, well-designed epidemiologic studies on patients with UIA should include more representative samples, assess for predictors of psychological outcomes, and explore the most optimal psychiatric assessment tools.

Depression and Anxiety after Stroke in Young Adult Filipinos.

BACKGROUND AND OBJECTIVES: Young adult patients may suffer from poststroke depression (PSD) and anxiety. Few studies have evaluated these important psychiatric conditions that may lead to adverse outcomes in young adults. We aimed to determine the prevalence of PSD and anxiety as well as to identify their predictors in a population of young Filipino adults (18-49 years old). METHODS: We performed a cross-sectional epidemiologic study in the largest tertiary hospital in the Philippines. The study involved the administration of a structured survey tool and review of medical records. The Hospital Anxiety and Depression Score - Pilipino version (HADS-P) was used to screen for anxiety and depression. Multivariable logistic regression analysis was performed to determine significant socio-economic and clinical risk factors of PSD and anxiety. RESULTS: 114 young adult stroke patients were included. The prevalence of depression was 20.2% while that of anxiety was 34.2%. Significant predictors of PSD were the presence of anxiety (OR 1.84; CI 1.05-3.22), lower mRS scores (mRS 3-5 OR 5.52; 95% CI 1.09-8.03) and diabetes (OR 2.09; 95% CI 1.67-6.26). Meanwhile, significant predictors of poststroke anxiety included depression (OR 7.5; 95% CI 5.02-21.94) and dependency (Barthel Index scores 95-100; OR 0.94; 95% CI 0.89-0.99). Relationship status, educational attainment, stroke subtype and location were not found to be significant predictors of PSD and anxiety. CONCLUSION: A significant proportion of young adults suffered from depression and anxiety after stroke. Clinicians should be aware of these psychiatric conditions that influence outcomes and quality of life of young adults with stroke.

Efficacy of aspirin for sporadic vestibular schwannoma: a meta-analysis.

BACKGROUND: Pharmacologic treatment of vestibular schwannomas (VSs) may increase the success of conservative management for small lesions, and offer an alternative to surgery and stereotactic radiotherapy in symptomatic cases in the high-risk population. Agents that have been studied include aspirin (ASA), but the results of the preliminary studies have been conflicting. In this study, we aimed to systematically review the evidence on the effect of ASA intake on tumor growth in patients with VSs. METHODS: Pubmed, Cochrane, Scopus, Embase, ClinicalTrials.gov , and Web of Science were searched for studies comparing VS tumor growth in patients with aspirin intake and those without. Random-effect meta-analysis was used to evaluate the outcomes in terms of linear and/or volumetric tumor growth. RESULTS: Four retrospective cohort studies were included in the meta-analysis. No significant difference was found in tumor growth between VS patients with aspirin intake and those without. This result held true for the analysis of linear tumor growth (OR 1.23; 95% CI 0.49, 3.10), volumetric tumor growth (OR 1.41; 95% CI 0.36, 5.59), and both combined (OR 1.02; 95% CI 0.56, 1.86). CONCLUSIONS: Our meta-analysis suggests that there is insufficient evidence to recommend ASA therapy in patients with VSs. High-quality randomized controlled trials are warranted to determine the efficacy of this drug in reducing VS tumor growth.

Teaching NeuroImage: Rapidly Changing Symptoms With Multistep Migration of Clot in the Posterior Circulation After Tenecteplase for Acute Ischemic Stroke.

A 70-year-old man presented with acute vertigo and ataxia. CT angiogram revealed left V3 segment vertebral artery occlusion (Figure 1, A and B). He received tenecteplase (0.25 mg/kg IV bolus) and was transferred to our comprehensive stroke center due to the risk of early neurologic deterioration from clot migration that would necessitate thrombectomy. Repeat CT angiogram revealed migration to V4 segment with posterior inferior cerebellar artery reopacification and improving symptoms (Figure 1, C and D). Two hours post-tenecteplase, he developed aphasia, right hemianopia, and sensorimotor symptoms (National Institutes of Health Stroke Scale 15). Angiogram showed a left P1 posterior cerebral artery thrombus. Attempted thrombectomy resulted in further migration to P2. MRI demonstrated multiple infarcts (Figure 2), representing stepwise ischemia from dynamic clot movement. Clot reformation from hypercoagulability or re-embolization seemed unlikely, given short time course and exclusive posterior circulation involvement.

Missed pituitary microadenoma during endoscopic transsphenoidal surgery for short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing with symptom relief: illustrative case.

BACKGROUND: Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a rare headache disorder that has been associated with pituitary adenomas. Resection has been posited to be curative. OBSERVATIONS: A 60-year-old female presented with a 10-year history of SUNCT, which had been medically refractory. Sellar magnetic resonance imaging (MRI) showed a 2 × 2 mm nodule in the right anterolateral aspect of the pituitary. Endoscopic endonasal transsphenoidal resection of the pituitary microadenoma with neuronavigation was performed. The patient felt immediate relief from the headaches. Postoperative MRI showed persistence of the pituitary microadenoma and the resection tract to be inferomedial to the lesion. The right middle and partial superior turbinectomy site was close to the sphenopalatine foramen (SPF). The patient was discharged on postoperative day 1 and remained headache-free without any medications at the 4-month follow-up. LESSONS: Resection of pituitary lesions associated with SUNCT may not necessarily be the cause of SUNCT resolution. Manipulation of the middle and superior turbinate close to the SPF may lead to a pterygopalatine ganglion block. This may be the mechanism of cure for SUNCT in patients with related pituitary lesions who undergo endonasal resection.

Top 100 Most Cited Neurologic and Neurosurgical Articles on COVID-19: A Bibliometric Analysis.

OBJECTIVE: With the exponential growth of literature on coronavirus disease 2019 (COVID-19), we aimed to identify and characterize the 100 most cited COVID-19-related articles in neurology and neurosurgery. METHODS: In March 2021, we performed a title-specific search of the Scopus database using ("neurology" or "neurologic" or "neurosurgery" or "neurosurgical") and "COVID" as our search query term without date restrictions. The top 100 most cited English-language articles were obtained and reviewed. RESULTS: Our search yielded 9648 articles published from December 2019 to March 2021. Bibliometric analysis of the top 100 articles found that the most cited article had a citation count of 1741 and was the first to report on the detailed neurologic manifestations of the disease; Neurology had the most number of publications; the majority of the primary authors were neurologists, but 35% were from nonneuroscience specialties; the United States, Italy, the United Kingdom, China, and Germany were the top contributors, with a combined total of 77%; most of the publications were correspondence or editorial articles; and most articles discussed the neurologic manifestations and complications of patients with COVID-19. CONCLUSIONS: This study identified the top 100 most cited neurologic or neurosurgical COVID-19-related articles published to date. This list can be used to identify high-impact studies that will help health care practitioners in clinical decision making and researchers in navigating key areas of study and guiding future research.

Practice Patterns in Surgical Neuro-Oncology Among Low- and Middle-Income Countries During the Coronavirus Disease 2019 Pandemic: A Scoping Review and Situational Report from the Philippines.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has negatively affected the outcomes of surgical neuro-oncology patients worldwide. We aimed to review the practice patterns in surgical neuro-oncology in low- and middle-income countries (LMICs). We also present a situational report from our own country. METHODS: A scoping review was performed following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. RESULTS: Twelve studies were included in the review. Most of the studies were from Asia (India, China, Iran, and Turkey), and 1 was from Brazil. Quantitative reports showed a decrease in the number of surgical neuro-oncology operations between pre-COVID-19 and post-COVID-19 time frames, but similar proportions of neuro-oncology procedures. Qualitative review showed similar practice patterns between LMICs and high-income countries, except for limitations in resources such as negative-pressure operating rooms and intensive care units, and maintenance of face-to-face consults despite the adoption of telemedicine. Limited data on adjuvant therapy were available in LMICs. CONCLUSIONS: In our review, we found that the practice patterns in surgical neuro-oncology in LMICs during the COVID-19 pandemic are similar to those in high-income countries, except for a few modifications because of resource limitation and patient preferences.

Predictive Value of Hematologic Inflammatory Markers in Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage.

BACKGROUND AND OBJECTIVE: Our study aimed to determine the ability of hematologic markers (neutrophil/lymphocyte ratio [NLR], platelet/lymphocyte ratio, and red cell distribution width [RDW]) in predicting delayed cerebral ischemia (DCI), modified Rankin Scale scores, and mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH). METHODS: A retrospective observational 6-year review of medical records was conducted to identify all consecutive patients with aSAH admitted to the largest training hospital in the Philippines. Univariable and multivariable regression analyses were performed to determine the association of the biomarkers with the respective outcomes. Receiver operating characteristic curves were used to detect overall predictive accuracy. RESULTS: A total of 222 patients with aSAH were included, of whom 11.71% developed DCI. Most patients with NLR ≥5.9 subsequently died (77 vs. 52%; P = 0.03). DCI was also associated with poor functional outcomes with higher modified Rankin Scale scores (3-6) on discharge (92% vs. 49%; P < 0.01), and longer duration of hospitalization (median, 20 vs. 13 days; P = 0.01). In receiver operating characteristic analyses, the value of RDW was predictive for DCI (area under the curve, 0.70; 95% confidence interval, 0.62-0.79; P < 0.01). The values of NLR (area under the curve, 0.67; 95% CI, 0.59-0.74) potentially predict functional outcome. RDW, NLR, and their combinations were poor discriminators of mortality. CONCLUSIONS: Our study showed that some hematologic parameters analyzed could be of potential value as prognostic biomarkers in patients with aSAH. Hematologic biomarkers are widely available and practical parameters that may be of considerable clinical value in aSAH management, especially in lower-middle-income countries such as the Philippines.

Paving the Path to Wellness: A Systematic Review of Wellness Programs for Neurosurgery Trainees.

BACKGROUND: Neurosurgical trainees have a heavy workload and poor quality of life, resulting in high rates of burnout and attrition. Consequently, wellness programs have been used by various training institutions to combat this situation. OBJECTIVE: We aimed to identify and describe wellness programs available for neurosurgical trainees in their training institutions, the outcome measures used to assess them, and their efficacy. METHODS: A systematic review of the literature was made following PRISMA guidelines. RESULTS: Six studies were included in the review, describing wellness programs from 9 institutions. All programs except 1 used exercise as the core component. The other components included physical and mental well-being lectures, team-building activities, and cultural excursions. Most institutions used piloted satisfaction and perception questionnaires to assess efficacy. Trainee perceptions of wellness programs were generally positive, but the responses on validated questionnaires and surveys were mixed. Barriers to the program included lack of institutional support, time constraints, fatigue, and feelings of guilt in prioritizing wellness over patient care. CONCLUSIONS: There is a paucity of literature regarding trainee wellness in neurosurgery. A few training programs have instituted wellness initiatives for trainees, and the feedback was generally positive. However, objective measures of efficacy such as validated questionnaires and scales yielded mixed results.

Intraoperative radiotherapy for glioblastoma: A systematic review of techniques and outcomes.

BACKGROUND: Despite multimodality treatment, the prognosis of glioblastoma (GBM) has remained poor. Intraoperative radiation therapy (IORT) offers additional local control by directly applying a radiation source to the resection margin, where most recurrences occur. METHODS: We performed a systematic review on the oncologic outcomes and toxicities of IORT for GBM in the era of modern external beam radiation therapy (EBRT) and chemotherapy with temozolamide. RESULTS: Four studies representing 123 patients were included. Majority (81%) were newly diagnosed, and gross total resection was reported in 13-80% of cases. IORT modalities included electrons from a linear accelerator (LINAC) and photons from a 50-kV x-ray device. Median doses were from 12.5 to 20 Gy for electron-based studies and 10-25 Gy for photon-based studies. Adjuvant treatment consisted of 46-60 Gy post-operative EBRT in electron-based studies and the Stupp protocol in photon-based studies. Complications included radiation necrosis (2.8-33%), infection, hematoma, perilesional edema, and wound dehiscence. Median time to local recurrence was 9.9-16 months and the reported overall progression-free survival was 11.2-12.2 months. Median overall survival was 13-14.2 months for the electron-based studies and 13.8-18 months for the photon-based studies. CONCLUSION: IORT resulted in improved local control and comparable overall survival rates with the Stupp protocol. Although photon-based IORT had better results than electron IORT, this may be due to improvements in other forms of adjuvant treatment rather than the IORT modality itself. The overall effect of IORT on GBM treatment is still inconclusive due to the small number of patients and heterogeneous reporting of data.

Awake Craniotomy in Low-Resource Settings: Findings from a Retrospective Cohort in the Philippines.

BACKGROUND: Awake craniotomy is a technique used to maximize resection of lesions in eloquent areas of the brain and preserve function. Although its use in high-income centers is well documented for tumors and vascular lesions, reports of its use in low-middle-income countries are limited. There are no published series from the Philippines. METHODS: We performed a retrospective review of all patients who underwent awake craniotomy at a tertiary referral center in Manila, Philippines from 2010 to 2019. Data on demographics, clinical features, diagnoses, intraoperative and postoperative complications, and outcomes were collected. Regression analyses were performed to correlate use of intraoperative adjuncts with outcome measures (extent of resection, complication rate, neurologic status after surgery and on last follow-up, and in-hospital mortality). RESULTS: A total of 65 patients were included in the cohort, who had a male predilection (60%) and a mean age at diagnosis of 40.4 years. The most common indication was tumor excision (90%), followed by excision of arteriovenous malformations (5%) and cavernomas (3%). Of the tumors, the most common histopathologic diagnosis was low-grade glioma (48%). The intraoperative complication rate was 13.8%, with the most common complication being patient intolerance. Gross total excision rate for tumors was 78.3%. Univariate analysis showed that use of a cortical stimulator was associated with improved neurologic status on last follow-up (P = 0.0471). CONCLUSIONS: Our experience shows that awake craniotomy is feasible in low-middle-income country settings and is safe and effective for excision of tumors, arteriovenous malformations, and cavernomas.

The current status and challenges in multiple sclerosis management in the Philippines.

BACKGROUND: The provision of adequate services for individuals living with multiple sclerosis (MS) is an important issue since MS has a chronic and debilitating course. OBJECTIVE: We aimed to review the literature on health service delivery for individuals with MS in the Philippines and identify the gaps in adequate provision of healthcare in these individuals. METHODS: We reviewed data from relevant local and international repositories on health service delivery for individuals with MS in the Philippines. RESULTS: The epidemiology of MS in the Philippine setting remains unknown. Approximately 1 neurologist caters to 175,000 Filipinos aged 15 and above, and nearly half are practicing in the National Capital Region. Physical access to magnetic resonance imaging is severely limited at 0.8 MRI unit per million Filipinos. Household out-of-pocket payment and voluntary health care payment schemes contributed 53.9% and 12.2%, respectively, to the current health expenditures. The average monthly income of a Filipino household is only 519 USD which may not be enough to cover treatment of a single relapse let alone costly disease-modifying treatments. CONCLUSION: The Philippines faces challenges in terms of the availability of accurate epidemiologic information, resource allocation, access to services and provision of therapies for individuals with MS.

Re-examining the exclusion criterion of early recurrent ischemic stroke in intravenous thrombolysis: A meta-analysis.

BACKGROUND: Current guidelines preclude the administration of intravenous tissue plasminogen activator in patients with early recurrent stroke (prior ischemic stroke within three months). OBJECTIVES: This is a meta-analysis that aimed to determine the safety and efficacy of thrombolysis in patients with early recurrent stroke. SUMMARY OF REVIEW: Pubmed, Cochrane, Scopus, Embase and Clinicaltrials.gov were searched for studies comparing the outcomes of acute ischemic stroke patients undergoing intravenous thrombolysis between those with early recurrent stroke and those without. Random-effects meta-analysis was used to evaluate the outcomes in terms of symptomatic intracranial hemorrhage, mortality and good functional outcomes at 3 months (modified Rankin Score ≤ 2). Three retrospective cohort studies with a total of 48,459 thrombolysed patients (824 with early recurrent stroke and 47,635 without early recurrent stroke) were included in the meta-analysis. There was no significant difference between thrombolysed patients with early recurrent stroke and those without in terms of symptomatic intracranial hemorrhage (Odds Ratio [OR] 1.39, 95% Confidence Interval [CI] 0.75-2.58), mortality (OR 1.36, 95% CI 0.60-3.09) and good functional outcomes at 3 months (OR 0.74, 95% CI 0.47-1.16). CONCLUSIONS: Patients who received thrombolysis despite early recurrent stroke were not found to be at an increased risk of adverse outcomes compared to patients without early recurrent stroke. Our meta-analysis suggests that there is insufficient evidence to substantiate excluding patients with early recurrent stroke from receiving thrombolysis. Further studies to re-examine early recurrent stroke as an exclusion criterion for receiving thrombolysis are warranted.

Secondary hypokalemic paralysis with bulbar weakness and reversible electrophysiologic abnormalities: A case report and systematic review.

Hypokalemic periodic paralysis secondary to distal renal tubular acidosis presenting with prominent bulbar symptoms is extremely rare. The exact pathophysiology by which hypokalemia causes weakness is yet to be elucidated though muscle and nerve membrane hyperpolarization have been hypothesized. The pathophysiology of bulbar involvement in this condition is even more unclear. We report a case presenting as acute flaccid quadriplegia with prominent bulbar symptoms that reversed once potassium levels returned to normal. Serial nerve conduction studies were performed at various potassium levels revealing electrophysiologic abnormalities that corrected with potassium repletion. A systematic review of the literature was also conducted focusing on bulbar symptoms and electrophysiologic findings in hypokalemic periodic paralysis. Nerve conduction abnormalities in this condition are seldom documented, but reports have shown reduced amplitudes of compound motor action potentials and abnormal F-waves during acute attacks of hypokalemic paralysis.
