Presentation, management, and outcomes of pediatric hydrocephalus in Africa: a systematic review and meta-analysis of 12,355 patients.

OBJECTIVE: The prevalence, management, and outcomes of hydrocephalus remain underexplored in Africa. This study aimed to analyze demographic and clinical features, evaluate treatment strategies, and assess neurological outcomes of pediatric hydrocephalus in Africa. METHODS: A systematic review of the literature using the PubMed, Google Scholar, and Web of Science electronic databases was completed according to the PRISMA guidelines to identify articles describing pediatric patients in Africa with hydrocephalus. RESULTS: Seventy-four retrospective and prospective studies and 33 case reports involving 12,355 patients were included. In 54 retrospective articles reporting patient demographics, 53.8% (3926/7297) were male with a mean age of 12.3 months. Nineteen studies reported macrocephaly (80.2%, 1639/2043) as the most common presentation. The etiology of hydrocephalus was reported as postinfectious (41.0%, 2303/5614) across 27 articles and congenital (48.6%, 1246/2563) in 10 articles. Eleven articles reported 46.7% (609/1305) of patients had communicating hydrocephalus while 53.3% (696/1305) had obstructive hydrocephalus. Diagnostic imaging included CT (76.1%, 2435/3202; n = 29 articles), ultrasonography (72.9%, 2043/2801; n = 15 articles), and MRI (44.8%, 549/1225; n = 11 articles). In 51 articles, 83.1% (7365/8865) of patients had ventriculoperitoneal shunting (VPS) while 33 articles described 54.1% (2795/5169) receiving endoscopic third ventriculostomy (ETV) for hydrocephalus surgical management. Postoperative complications included sepsis (6.9%, 29/421; n = 4 articles), surgical site infections (5.1%, 11/218; n = 4 articles), and CSF leaks (2.0%, 15/748; n = 8 articles). Shunt-related complications included infections (4.3%, 117/2717; n = 21 articles) and blockages (4.1%, 34/829; n = 6 studies). In 15 articles, 9.0% (301/3358) of patients with shunts had revisions. The mean follow-up duration was 18.9 ± 16.7 months with an overall mortality rate of 7.4% (397/5383; n = 29 articles). In the analysis of comparative studies, the 160 patients undergoing ETV demonstrated significantly higher odds of a successful operation (OR 1.54, 95% CI 0.51-4.69; p = 0.03) and neurological improvement at last follow-up (OR 3.36, 95% CI 0.46-24.79; p < 0.01) compared with the 158 who received VPS, but no significant differences were observed for complications and mortality between the two groups (p > 0.05). CONCLUSIONS: This review offers a comprehensive summary of pediatric hydrocephalus in Africa, highlighting shunting as the primary treatment. However, the observed variations across studies highlight the need to establish standardized guidelines for reporting patient characteristics, management strategies, and outcomes to ensure consistency and comparability in articles.

Implications for neurosurgery of medical schools leaving the United States News and World Report.

Ranked lists are a highly praised method of assessment in America. Whether it's a list of the top national sports teams, the best restaurants in New York City, or as in this case, the strongest educational institutions, we look to rankings to scrutinize, evaluate, and compare. Unfortunately, not all rankings offer insightful and valuable information. Many use metrics that fall short of an accurate representation of the desired outcome. The U.S. News & World Report (USNWR), one of the most widely regarded rankings of educational institutions, has recently been under the spotlight as several major medical schools have removed themselves from candidate lists. The current USNWR Medical School's rankings are regarded as having a narrow perspective in that the metrics perpetuate a less diverse medical community and fail to recognize worthy institutions that choose to champion a well-rounded student experience. The authors, along with the many others, fear this may deliver a skewed vision of what the USNWR tries to measure: the excellence of a medical education.

African Women in Neurosurgery: An Exploration of Historical Perspectives, Current Realities, and Future Prospects.

BACKGROUND: Gender disparities remain a significant issue, particularly impacting African women in the field of neurosurgery. METHODS: Databases, articles, and perspectives were reviewed to identify challenges faced by African Women in Neurosurgery (AWIN), and explore solutions for recruitment, retention, and career advancement of AWIN. RESULTS: In 1982, Africa saw its first female neurosurgeon, with the first female president of the World Federation of Neurosurgical Societies appointed 4 null decades later. Presently, the continent hosts 245 female neurosurgeons, with North Africa comprising the majority at 76.3%, with Algeria notably contributing 72.2% of this total. Southern Africa contributes 7.8%, while West Africa, East Africa, and Central Africa contribute 6.5%, 6.1%, and 3.3%, respectively. Thirteen countries lack neurosurgeons entirely and 30 out of the 54 African nations face shortages of female neurosurgeons, with distributions as follows: North Africa (1-country), Southern Africa (6-countries), West Africa (8-countries), East Africa (9-countries), and Central Africa (6-countries). Our analysis mapped the distribution of 245 AWIN across the African regions and examined the professional trajectories and achievements of 17 pioneering AWIN. Additionally, we compiled registries for: 1) 76 neurosurgical training programs across 26 African countries, 2) organizations tackling gender disparities in neurosurgery, and 3) recommendations to promote AWIN across governmental, community, and academic spheres. CONCLUSIONS: To boost AWIN representation in neurosurgery, concerted and comprehensive efforts are vital. Collaboration among medical schools, training programs, and governments is key to fostering diversity and inclusivity in African neurosurgical settings.

Back to Basics: Care of the Stereotactic EEG Implanted Patient.

PURPOSE: Stereotactic EEG (SEEG) is gaining increasing popularity in the United States. Patients undergoing SEEG have unique challenges, and their needs are different compared with noninvasive cases. We aim to describe the medical, nursing, and other institutional practices of SEEG evaluations among tertiary referral (level IV) epilepsy centers accredited by the National Association of Epilepsy Centers. METHODS: We analyzed data obtained from a Research Electronic Data Capture (REDCap) survey we formulated and distributed to directors of all level IV epilepsy centers listed by the National Association of Epilepsy Center. Most questions were addressed to the adult and pediatric SEEG programs separately. RESULTS: Among 199 epilepsy center directors invited to complete the survey, 90 (45%) responded. Eighty-three centers (92%) reported they perform SEEG evaluations. Of the 83 respondents, 56 perform SEEG in adult and 47 in pediatric patients. Twenty-two centers evaluate both pediatric and adult subjects. The highest concordance of SEEG workflow was in (1) epilepsy monitoring unit stay duration (1-2 weeks, 79% adult and 85% pediatric programs), (2) use of sleep deprivation (94% both adult and pediatric) and photic stimulation (79% adult and 70% pediatric) for seizure activation, (3) performing electrical cortical stimulation at the end of SEEG evaluation after spontaneous seizures are captured (84% adult and 88% pediatric), and (4) daily head-wrap inspection (76% adult and 80% pediatric). Significant intercenter variabilities were noted in the other aspects of SEEG workflow. CONCLUSIONS: Results showed significant variability in SEEG workflow across polled centers. Prospective, multicenter protocols will help the future development and harmonization of optimal practice patterns.

Predictors of Admission to Post-Acute Rehabilitation Following Multi-Level Spinal Decompression and Fusion Surgery and Its Associated Outcomes.

OBJECTIVE: To investigate predictive factors and outcomes in those admitted to post-acute rehabilitation (PAR) versus those that discharged home following multi-level spinal decompression and fusion surgery. METHODS: Retrospective case review study of adults that underwent multi-level spinal decompression and fusion surgery between 2016 and 2022 at an academic institution. Preoperative, perioperative, postoperative, and outcomes variables were compared between those discharged home versus PAR. Finally, multiple logistic regression was used to determine factors contributing to PAR admission. RESULTS: Of 241 total patients, 89 (37%) discharged home and 152 (63%) discharged to PAR. Among home discharge patients, 45.9% used an assistive device, while among PAR patients, 61.5% used 1 (P = 0.041). Mean pre-operative Oswestry Disability Index score was significantly lower in the home discharge group compared to the PAR discharge group (40.3 vs. 45.3 respectively, P = 0.044). Females were 2.43 times more likely to be discharged to PAR compared to males (95% CI: 1.06, 5.54, P = 0.04). Patients with a mood disorder had 2.81 times higher odds of being discharged to PAR compared to those without (95% CI: 1.20, 6.60, P = 0.02). Other variables evaluated were not statistically significant. CONCLUSIONS: Female sex and presence of a mood disorder increase the likelihood to PAR discharge following multi-level spinal decompression surgery.

Real-Time Seizure Detection Using Behind-the-Ear Wearable System.

INTRODUCTION: This study examines the usability and comfort of a behind-the-ear seizure detection device called brain seizure detection (BrainSD) that captures ictal electroencephalogram (EEG) data using four scalp electrodes. METHODS: This is a feasibility study. Thirty-two patients admitted to a level 4 Epilepsy Monitoring Unit were enrolled. The subjects wore BrainSD and the standard 21-channel video-EEG simultaneously. Epileptologists analyzed the EEG signals collected by BrainSD and validated it using video-EEG data to confirm its accuracy. A poststudy survey was completed by each participant to evaluate the comfort and usability of the device. In addition, a focus group of UT Southwestern epileptologists was held to discuss the features they would like to see in a home EEG-based seizure detection device such as BrainSD. RESULTS: In total, BrainSD captured 11 of the 14 seizures that occurred while the device was being worn. All 11 seizures captured on BrainSD had focal onset, with three becoming bilateral tonic-clonic and one seizure being of subclinical status. The device was worn for an average of 41 hours. The poststudy survey showed that most users found the device comfortable, easy-to-use, and stated they would be interested in using BrainSD. Epileptologists in the focus group expressed a similar interest in BrainSD. CONCLUSIONS: Brain seizure detection is able to detect EEG signals using four behind-the-ear electrodes. Its comfort, ease-of-use, and ability to detect numerous types of seizures make BrainSD an acceptable at-home EEG detection device from both the patient and provider perspective.

Neuromodulation of the anterior thalamus: Current approaches and opportunities for the future.

The role of thalamocortical circuits in memory has driven a recent burst of scholarship, especially in animal models. Investigating this circuitry in humans is more challenging. And yet, the development of new recording and stimulation technologies deployed for clinical indications has created novel opportunities for data collection to elucidate the cognitive roles of thalamic structures. These technologies include stereoelectroencephalography (SEEG), deep brain stimulation (DBS), and responsive neurostimulation (RNS), all of which have been applied to memory-related thalamic regions, specifically for seizure localization and treatment. This review seeks to summarize the existing applications of neuromodulation of the anterior thalamic nuclei (ANT) and highlight several devices and their capabilities that can allow cognitive researchers to design experiments to assay its functionality. Our goal is to introduce to investigators, who may not be familiar with these clinical devices, the capabilities, and limitations of these tools for understanding the neurophysiology of the ANT as it pertains to memory and other behaviors. We also briefly cover the targeting of other thalamic regions including the centromedian (CM) nucleus, dorsomedial (DM) nucleus, and pulvinar, with associated potential avenues of experimentation.

Perceptions on Management of Atopic Dermatitis in Children Under 2 Years by Community Pediatricians: A Focus Group Study.

Atopic dermatitis (AD) is a common skin condition and is undertreated in children under 2 years, whom there are no specific guidelines for. We sought to understand barriers to AD treatment and primary care pediatricians' (PCPs) suggested solutions. We conducted semi-structured focus groups (n = 5) with PCPs (n = 17) on how the undertreatment of AD can be addressed. Data were analyzed using an inductive qualitative approach. Participants noted that the perceived undertreatment of AD in children under 2 years could be explained by topical corticosteroid (TCS) use hesitancy, lack of caregiver adherence to PCP recommendations, and under-documentation of AD in the electronic medical record (EMR). Proposed suggestions for improving AD management included caregiver and PCP education on TCS safety; stepwise management guidelines for this age group; and EMR aids to help document and manage AD. Research is warranted to create and disseminate clinician-friendly AD management guidelines for this age group.

The impact of the ban on elective surgery in New York City during the coronavirus outbreak on gynecologic oncology patient care.

Introduction: Elective surgical procedures were suspended during the coronavirus disease pandemic (COVID-19) in New York City (NYC) between March 16 and June 15, 2020. This study characterizes the impact of the ban on surgical delays for patients scheduled for surgery during this first wave of the COVID-19 outbreak. Methods: Patients who were scheduled for surgical treatment of malignant or pre-invasive disease by gynecologic oncologists at three NYC hospitals during NYC's ban on elective surgery were included. Outcomes of interest were the percentage of patients experiencing surgical delay and the nature of delays. Kruskal-Wallis, chi-square, and logistic regression tests were performed with significance set at p < 0.05. Results: Of the 145 patients with malignant or pre-invasive diseases scheduled for surgery during the ban on elective surgery, 40% of patients experienced one or more surgical delays, 10% experienced two or more and 1% experienced three surgical delays. Of patients experiencing an initial delay, 77% were hospital-initiated and 11% were due to known or suspected personal COVID-19. Overall, 81% of patients completed their planned treatment, and 93% of patients underwent their initially planned surgery. Among patients for whom adjuvant therapy was recommended, 67% completed their planned treatment, and the most common reasons for not completing treatment were medically indicated followed by concerns regarding COVID-19. Conclusion: During the ban on elective surgery in NYC during the first outbreak of the COVID-19 pandemic, many patients experienced minor surgical delays, but most patients obtained appropriate, timely care with either surgery or alternative treatment.

Predictors of severe and critical disease in pregnant women with SARS-CoV-2.

BACKGROUND/OBJECTIVE: SARS-CoV-2 continues to spread widely in the US and worldwide. Pregnant women are more likely to develop severe or critical illness than their non-pregnant counterparts. Known risk factors for severe and critical disease outside of pregnancy, such as asthma, diabetes, and obesity have not been well-studied in pregnancy. We aimed to determine which clinical and pregnancy-related factors were associated with severe and critical COVID illness in pregnancy. STUDY DESIGN: This was a retrospective cohort study of women with confirmed intrauterine pregnancy and positive nasopharyngeal swab for SARS-CoV-2 who presented to an academic medical center in New York City from 1 March 2020 to 1 July 2020. Severe and critical COVID-19 disease was defined by World Health Organization criteria. Women with severe/critical disease were compared to women with asymptomatic/mild disease. Continuous variables were compared with Mann-Whitney or t-test and categorical variables were compared using chi-square and Fisher's exact. Statistical significance was set at p < .05. Multivariable logistic regression was performed including variables that were significantly different between groups. RESULTS: Two hundred and thirty-three patients were included, 186 (79.8%) with asymptomatic/mild disease and 47 (20.2%) with severe/critical disease. Women with asymptomatic/mild disease were compared to those with severe/critical disease. Women with severe/critical disease were more likely to have a history of current or former smoking (19.6 vs. 5.4%, p = .004), COVID-19 diagnosis in the 2nd trimester (42.6 vs. 11.8%, p = .001), and asthma or other respiratory condition (21.3 vs. 7.0%, p = .01). Women with severe/critical disease were more likely to have cesarean delivery (35.5 vs. 15.6%, p < .01) and preterm delivery <37 weeks (25.8 vs. 3.8%, p < .01). After adjustment, history of smoking remained significantly predictive of severe/critical disease [aOR 3.84 (95% CI, 1.25-11.82)]. CONCLUSION: Pregnant women with a history of smoking, asthma, or other respiratory condition, and COVID-19 diagnosis in the second trimester of pregnancy were more likely to develop severe/critical disease. These findings may be useful in counseling women on their individual risk of developing the severe or critical disease in pregnancy and may help determine which women are good candidates for vaccination during pregnancy.

Innate Immune Cytokine Profiling and Biomarker Identification for Outcome in Dengue Patients.

Background: Early biomarkers of progression to severe dengue are urgently required to enable effective patient management and control treatment costs. Innate immune cells, which comprise the earliest responders to infection and along with the cytokines and chemokines they secrete, play a vital role in orchestrating the subsequent adaptive immune response and have been implicated in the enhancement of infection and "cytokine storm" associated with dengue severity. We investigated the early innate immune cytokine profile of dengue patients during acute phase of disease in a prospective blinded study that included subjects with acute dengue and febrile controls from four major hospitals in Bengaluru, India along with healthy controls. We used intracellular cytokine staining and flow cytometry to identify innate immune biomarkers that can predict progression to severe dengue. Results: Dengue infection resulted in enhanced secretion of multiple cytokines by all queried innate immune cell subsets, dominated by TNF-α from CD56+CD3+ NKT cells, monocyte subsets, and granulocytes along with IFN-γ from CD56+CD3+ NKT cells. Of note, significantly higher proportions of TNF-α secreting granulocytes and monocyte subsets at admission were associated with mild dengue and minimal symptoms. Dengue NS1 antigenemia used as a surrogate of viral load directly correlated with proportion of cytokine-secreting innate immune cells and was significantly higher in those who went on to recover with minimal symptoms. In patients with secondary dengue or those with bleeding or elevated liver enzymes who revealed predisposition to severe outcomes, early activation as well as efficient downregulation of innate responses were compromised. Conclusion: Our findings suggested that faulty/delayed kinetics of innate immune activation and downregulation was a driver of disease severity. We identified IFN-γ+CD56+CD3+ NKT cells and IL-6+ granulocytes at admission as novel early biomarkers that can predict the risk of progression to severity (composite AUC = 0.85-0.9). Strong correlations among multiple cytokine-secreting innate cell subsets revealed that coordinated early activation of the entire innate immune system in response to dengue virus infection contributed to resolution of infection and speedy recovery.
