COVID-19 impact on the global neurosurgery resident training course and admission: A scoping review.

Background: This study looks at how COVID-19 affected the admission and training of neurosurgical residents worldwide. Methods: From 2019 to 2021, we reviewed multiple databases (i.e., Google Scholar, Science Direct, PubMed, and Hinari) to evaluate the impact of the COVID-19 pandemic on neurosurgery resident training and admission in low middle-income countries (LMICs) and high-income countries (HICs). We then utilized a Wilcoxon signed-rank test to evaluate the difference between the two LMIC/HICs and employed Levene's test to assess the homogeneity of variances. Results: There were 58 studies that met our inclusion criteria; 48 (72.4%) were conducted in HIC and 16 (27.6%) in LMIC. The admission of new residents was mostly canceled in HIC (31.7%; n = 13) and in LMIC (25%; n = 4) from 2019 to 2021 due to COVID-19. Learning modalities changed to include predominantly video conferencing (i.e., 94.7% [n = 54] of cases). Further, neurosurgery was largely restricted to emergency cases alone (79.6% [n = 39]), with only 12.2% (n = 6) elective cases. The result was a marked reduction in resident surgical training (i.e., 66.7% [n = 10] in LMIC and 62.9% [n = 22] in HIC), despite increased workloads in (i.e., LMIC [37.4%; n = 6] and HIC [35.7%; n = 15]). This was attributed to the marked reduction in the number of surgical patients allotted to each resident (i.e., LMIC [87.5%; n = 14] than HIC [83.3%; n = 35]). Conclusion: The COVID-19 pandemic markedly disrupted neurosurgical education globally. Although differences have been found between LMICs and HICs training, the reduction of neurosurgical case-loads and surgical procedures has significantly impacted neurosurgical training. The question remains, how can this "loss of experience" be redressed in the future?

Surgical Aneurysm Repair of Aneurysmal Subarachnoid Hemorrhage in Sub-Saharan Africa: The State of Training and Management.

BACKGROUND: In a resource-limited setting such as sub-Saharan African countries, neurosurgeons need training and fellowship for surgical repair of aneurysmal subarachnoid hemorrhage (aSAH). Surgical repair of ruptured aneurysms costs less and requires less instrumentation compared with endovascular procedures. The purpose of this study is to evaluate the state of training and management of aSAH in sub-Saharan Africa training centers. METHODS: An e-survey was sent as a Google Form to neurosurgeons and neurosurgical trainees in neurosurgery training centers in sub-Saharan Africa; responses were accepted from September 9 to October 23, 2022. Statistical analysis was performed using Microsoft Excel and JAMOVI 3.2. RESULTS: All 44 centers from 17 countries responded. Most of the respondents were neurosurgery residents (n = 30; 68.18%). The level of training on clipping was basic after completing the residency program (n = 18; 40.91%). Twenty respondents (45.45%) identified that fellowships on aneurysmal clipping and endovascular treatment are offered abroad. Thirteen participants (29.55%) indicated that endovascular treatment is available at their institutions. The most common challenges with lack of training for neurosurgical aneurysm clipping were scarce scholarship and collaboration with training centers from high-income countries (n = 33; 75%). The availability of intensive care unit beds also contributed to the presence of neurosurgical training of aneurysm clipping (12.1 ± 3.67 vs. 9.29 ± 5.82; P = 0.05). CONCLUSIONS: In sub-Saharan African countries, the lack of collaborations with high-income countries for training through fellowships of young neurosurgeons for aneurysm repair seems to be the most important challenge that should be overcome.

Transcranial doppler in the non-invasive estimation of intracranial pressure in traumatic brain injury compared to other non-invasive methods in lower-middle income countries: Systematic review and meta-analysis.

BACKGROUND: The prediction of raised Intracranial Pressure (ICP) with accuracy in Traumatic Brain Injury (TBI) patients is a clinically important decision and therapeutic tool. This study aimed to evaluate the existing methods used for non-invasive ICP monitoring in TBI patients in LMICs. METHODS: Systematic searches of PubMed, Google Scholar, and ScienceDirect were performed from database inception to November 2021. Studies reporting the prediction of raised ICP in TBI patients by non-invasive means in LMICs were included. Pooled estimates of sensitivity, specificity, positive likelihood ratios, and negative likelihood ratios with 95 %CI were calculated for each index test consisting of the fifteen studies, using the MEDDECIDE module 0.0.2 for meta-analysis of diagnostic test accuracy, reliability, and decision studies in JAMOVI 2.2.5. RESULTS: A total of 1032 studies were identified, of which, 15 included 3316 patients with male predominance (n = 2458, 74.13%). Patients' ages range from 15 to 96 years with 40-80 (n = 1205, 36.34%), the most represented population. The ICP measured by Transcranial Doppler (TCD) had a sensitivity of 92.3%, and a specificity of 70%. The positive predictive value was 66.67%, with a negative predictive value of 93.33%. Furthermore, the positive Likelihood Ratio (+LR) was 3.69; 2<+LR < 5 and the negative Likelihood Ratio (-LR) 0.103; 0.1 < -LR < 0.2. We carried out a "Medical Decision", "Plots", "Fagan Normogram" and the ROC curve to find the perfect discrimination point of all the five tests used for the non-invasive measurement of ICP in the TBI patients in LMICs. CONCLUSION: The TCD had shown high performance in its sensitivity and specificity, placing it on top of the other four different tests used in LMICs for the management of patients with TBI.
