Barriers to Neurosurgical Care of Brain Tumors in Low- and Middle-Income Countries: A Systematic Review of the Service Delivery Challenges.

INTRODUCTION: Brain tumors pose a major challenge in low- and middle-income countries (LMICs) due to limited resources and high costs, resulting in hampered service delivery of neurosurgical care and significant disparities in patient outcomes compared to high-income nations. Therefore, our systematic review aims to identify barriers to service delivery in providing adequate surgical care for the management of brain tumors in LMICs. METHODS: We searched Scopus, PubMed, Google Scholar, and CINAHL, from inception to October 20, 2022. The data from the eligible studies were extracted and analyzed qualitatively. RESULTS: The final analysis included 35 articles, which highlighted significant challenges in providing adequate surgical care for brain tumors in LMICs. Among the cited studies, 10% reported lack of multidisciplinary team structures, 61% noted delayed patient presentation, 16% highlighted delays in neuroimaging, 10% reported delays in scheduling surgery, lack of training for specialized surgery (3%), lack of intra-operative facilities (19%), power supply interruption (6%), and lack of advanced diagnostic and specialized surgery facilities (19%). Strategies for addressing these challenges include cross-border collaboration (7%), public education, and awareness (13%), establishing multidisciplinary teams (20%), utilizing alternative surgical techniques (13%), 7% intraoperative ultrasound, 13% intraoperative cytology smear), and establishing satellite hospitals for low-risk care (7%), standard operating procedure and infection control (13%). CONCLUSION: Targeted interventions considering economic constraints are essential to improve the availability, affordability, and quality of neuro-oncologic services in developing countries. International collaborations and building capacity are vital for improving patient outcomes and service delivery, as well as forming multidisciplinary teams and utilizing resource-saving, innovative methods.

Exploring the neurosurgery training landscape in Pakistan: A trainee's perspective in resource-limited settings.

Background: Shortage of neurosurgeons in Pakistan, one per 720,000 people, stems from a lack of trainees. Therefore, it is vital to assess the training experience, career opportunities, and satisfaction levels of neurosurgical trainees in Pakistan. Methods: A nationwide survey was conducted, covering 22 CPSP-accredited neurosurgery training programs in Pakistan. Convenience sampling was utilized with a pilot tested questionnaire and responses were analyzed using STATA 15. Results: The response rate was 98% (120/122) with 70.8% male and mean age of 30.4 ± 4.1 years. Training programs included teaching courses (79%) and journal club (66%); however, there was a lack of cadaver workshops (14%) and cranial model-based stimulation (22%). 67% of trainees lacked publications in indexed journals. 69% worked 50-100 h weekly, with 62% experiencing burnout due to workload and hours and a third reporting poor work-life balance. Trainees dedicated more to operating rooms (37%, 10-24 h/week) and clinics (34%, 24-48 h/week) compared to study (42%, <5 h/week) and research (64%, <5 h/week). Gender equality was rated poorly by 50%. Disparities emerged in subspecialty exposure, with over half of trainees lacking exposure to deep brain stimulation (67%), and epilepsy (75%). 52.5% of the training institutes did not offer fellowships and 64.1% of trainees planned to pursue fellowships abroad. Conclusions: Steps need to be taken to improve working hours, gender equity, and increase simulation courses, diversify subspecialty exposure, and promote research initiatives.

Effect of suprachoroidal triamcinolone on intraocular pressure: a systematic review and meta-analysis.

Background: Triamcinolone acetonide is a synthetic corticosteroid with multiple ocular uses. Like other corticosteroids, it too is associated with ocular side effects such as increased intraocular pressure (IOP), glaucoma and cataracts. Suprachoroidal administration of triamcinolone is hoped to reduce the ocular side effects of the drug, especially rises in IOP. Our systematic review and meta-analysis aims to study this phenomenon. Objectives: The purpose of this study was to evaluate the effect of suprachoroidal triamcinolone injections on IOP. Design: Systematic review and meta-analysis. Methods: We utilized the Medline, Scopus and Cochrane databases for this review. Studies published till June 2023, which fulfilled the eligibility criteria, were included. Studies in the English language with adult participants who were administered suprachoroidal triamcinolone without any concurrent intervention were included, whereas studies that did not report the mean and standard deviation for IOP were excluded. The outcome of interest was IOP at 1, 3 and 6 months post-suprachoroidal triamcinolone injection. IOP values from included studies were extracted onto Review Manager version 5.4 for analysis. Results: Our search yielded 104 results, from which 22 papers were shortlisted for full-text screening. Finally, 12 studies were included in the analysis. Our analysis suggests a statistically significant increase in IOP in the first month after suprachoroidal triamcinolone injection but no significant differences at 3 and 6 months post-injection as compared to baseline. Conclusion: Elevated IOP at 1 month post-injection must be considered when using suprachoroidal triamcinolone and adequate safety measures must be taken. However, the absence of a significant rise at 3 and 6 months post-injection indicates that this modality is safer than other existing drug delivery methods.

Gender Differences in Medical Students' Perception of Neurosurgery: A Cross-Sectional Study from Pakistan.

BACKGROUND: Despite 15,000 annual medical graduates, few choose neurosurgery, especially women. The scarcity of female neurosurgeons is a global concern, particularly in resource-limited settings such as Pakistan. This study focuses on gender-based differences in medical student perceptions of neurosurgery in Pakistan. METHODS: A nationwide cross-sectional study was conducted from March 6 to April 20, 2023, using a Web-based survey. Data collectors were recruited through an ambassadorship program, distributed evenly across all provinces. A questionnaire was used after a pilot study. Data analysis was performed using SPSS version 26 and STATA 15. RESULTS: A total of 2353 medical students participated in the study, of which 63.4% were female and 36.5% were male. Around 40.3% of women strongly agreed to the existence of potential gender bias in neurosurgery, in contrast to their corresponding male students, at 17.3%. Some of the highlighted deterring factors in pursuing neurosurgery as a career according to women include longer training duration (44.6%), poor work-life balance (41%), limited residency slots (50.6%), and limited exposure to neurosurgery (45.1%). Other factors included the high-intensity nature of training (33.6%), perceived gender bias (31.4%), competitive work environment (29.1%), complex surgical skills (38.6%), required level of medical knowledge (29.6%), and financial burden (33.9%). CONCLUSIONS: Our study shows that female students are more likely to believe in the existence of potential gender bias in the field compared with their counterpart male participants, which highlights the graveness of the situation in view of the evident paucity of female neurosurgeons in the country.

Risk factors and predictors of intraoperative seizures during awake craniotomy: A systematic review and meta-analysis.

Background: Awake craniotomy (AC) aims to minimize postoperative neurological complications while allowing maximum safe resection. Intraoperative seizures (IOSs) have been a reported complication during AC; however, literature delving into the predictors of IOS remains limited. Therefore, we planned a systematic review and meta-analysis of existing literature to explore predictors of IOS during AC. Methods: From the inception until June 1, 2022, systematic searches of PubMed, Scopus, the Cochrane Library, CINAHL, and Cochrane's Central Register of Controlled Trials were conducted to look for published studies reporting IOS predictors during AC. Results: We found 83 different studies in total; included were six studies with a total of 1815 patients, and 8.4% of them experienced IOSs. The mean age of included patients was 45.3 years, and 38% of the sample was female. Glioma was the most common diagnosis among the patients. A pooled random effect odds ratio (OR) of frontal lobe lesions was 2.42 (95% confidence intervals [CI]: 1.10-5.33, P = 0.03). Those with a pre-existing history of seizures had an OR of 1.80 (95% CI: 1.13-2.87, P = 0.01), and patients on antiepileptic drugs (AEDs) had a pooled OR of 2.47 (95% CI: 1.59-3.85, P < 0.001). Conclusion: Patients with lesions of the frontal lobe, a prior history of seizures, and patients on AEDs are at higher risk of IOSs. These factors should be taken into consideration during the patient's preparation for an AC to avoid an intractable seizure and consequently a failed AC.

Lifesaving skills training in schools - A qualitative study to explore students, teachers, and parent's perceived opportunities and challenges.

OBJECTIVE: The objective of this study is to explore the perception of teachers, parents and students' regarding implementation of a school-based lifesaving skills program and help predict potential barriers and solutions. METHODS: This qualitative exploratory study was conducted in Karachi, Pakistan, from December 2020- to October 2021. We included students, teachers, and parents of secondary (grades VIII, IX, and X) and higher secondary level students (grades XI and XII) in Karachi, Pakistan's public and private schools and colleges. We selected one public, two semi-private, and two private schools. We recruited students, teachers, and parents through convenience sampling. We conducted fifteen focus group discussions (FGDs) with the students, six FGDs with the teachers, and eighteen in-depth interviews (IDIs) with parents. We transcribed the data from audio recordings and translated it into the English language. Finally, we manually analyzed the data using thematic analyses. RESULTS: This study found that bystanders' main barriers to performing lifesaving skills are lack of knowledge, fear of legal involvement, fear of hurting the patient by incorrect technique, lack of empathy among community stakeholders, and gender bias. However, the participants had a positive and supportive attitude toward implementing lifesaving skills training in schools. They suggested starting student training in the early teenage years, preferred medical staff as trainers, and suggested frequent small sessions in English/Urdu both or Urdu language and training via theory and practical hands-on drills. Furthermore, the training was proposed to be integrated into the school curriculum to make it sustainable. Finally, the government needs to support the program and make the legal environment more conducive for bystanders. CONCLUSION: This study identified the significant barriers to performing lifesaving skills in an emergency in a low- and middle-income country (LMIC). The participants supported implementing a national lifesaving skills program in schools and colleges. However, the participants expressed that support is needed by the government for sustainability, integrating lifesaving skills into the school curriculum, providing legal support to the bystanders, and creating awareness among the general public.
