RESUMEN

BACKGROUND: Adjuvant therapy is an important tool in the arsenal of brain tumor management and can improve patients' outcomes significantly but low- and middle-income countries (LMICs) often face challenges in provision. Therefore, our study aims to highlight barriers and strategies to adjuvant therapy of brain tumors in low-resource settings. METHOD: A comprehensive search of literature was conducted using PubMed, CINAHL, Google Scholar, and Scopus, from inception to October 20, 2022. The review included studies on adjuvant therapy for brain tumors in LMICs and identified themes using the National Surgical, Obstetric, and Anesthesia Plan (NSOAP) domains. RESULTS: 32 studies were included in the review. The most reported barriers to adjuvant care were limited access to healthcare (14 %), limited access to chemotherapy and radiation equipment (25 %), and traditional or alternative medications (11 %). Strategies for improvement include improving the availability of specialized radiation oncology training (8 %) and improving access to neuro-diagnostics and neurotherapeutics (12 %). In addition, efforts to subsidize treatment (4 %) and provide financial coverage through the Ministry of Health (4 %) can help to address the high cost of care and improve access to funding for chemotherapy. Finally, establishing documentation systems and registries (16 %), implementing standardized national treatment guidelines (8 %) can help to improve overall care for brain tumor patients in LMICs. CONCLUSION: A multimodal approach of strategies targeting workforce, infrastructure, service delivery, financing, and information management is needed to improve adjuvant care for brain tumors. International collaboration and partnerships can also play a key role in addressing barriers and improving care in LMICs.

RESUMEN

BACKGROUND: Health care in developing countries often lacks adequate book-keeping and national cancer registries, means of information that have proven to impact disease research and care. The true burden of brain tumors therefore remains unchecked and so does the extent of the problem. Therefore, this study aims to explore the challenges and potential strategies related to information management of brain tumors in LMICs. METHODS: A comprehensive literature search conducted using databases such as PubMed, Scopus, Google Scholar, and CINAHL, without any language restrictions, from inception to October 20, 2022. Following screening and extraction of data, themes were generated using the information management domain of the National Surgical, Obstetric, and Anesthesia Plan (NSOAP) framework. RESULTS: The final analysis includes 23 studies which highlighted the challenges to managing information to the surgical care given to brain tumors in LMICs, including lack of proper hospital record system (43%), lack of national brain tumor registry (67%), lack of local management guidelines (10%), and low research output (33%). Some of the proposed strategies in the literature to address these barriers include improving data management systems (45%), developing a population-based brain tumor registry (64%), and formulating local treatment guidelines (9%) for the management of brain tumors. CONCLUSION: In LMICs, improving patient outcomes and quality of life post neurosurgical intervention for brain tumors requires coordinated efforts to enhance information systems. The support of the government and public health professionals is vital in implementing strategies to achieve this goal.

RESUMEN

BACKGROUND AND OBJECTIVES: Vague symptoms and a lack of pathognomonic features hinder the timely diagnosis of pediatric brain tumors (PBTs). However, patients in low- and middle-income countries (LMICs) must also bear the brunt of a multitude of additional factors contributing to diagnostic delays and subsequently affecting survival. Therefore, this study aims to assess these factors and quantify the durations associated with diagnostic delays for PBTs in LMICs. METHODS: A systematic review of extant literature regarding children from LMICs diagnosed with brain tumors was conducted. Articles published before June 2023 were identified using PubMed, Google Scholar, Scopus, Embase, Cumulative Index to Nursing and Allied Health Literature, and Web of Science. A meta-analysis was conducted using a random-effects model through R Statistical Software. Quality was assessed using the Newcastle Ottawa Scale. RESULTS: A total of 40 studies including 2483 patients with PBT from 21 LMICs were identified. Overall, nonspecific symptoms (62.5%) and socioeconomic status (45.0%) were the most frequently reported factors contributing to diagnostic delays. Potential sources of patient-associated delay included lack of parental awareness (45.0%) and financial constraints (42.5%). Factors contributing to health care system delays included misdiagnoses (42.5%) and improper referrals (32.5%). A pooled mean prediagnostic symptomatic interval was calculated to be 230.77 days (127.58-333.96), the patient-associated delay was 146.02 days (16.47-275.57), and the health care system delay was 225.05 days (-64.79 to 514.89). CONCLUSION: A multitude of factors contribute to diagnostic delays in LMICs. The disproportionate effect of these factors is demonstrated by the long interval between symptom onset and the definitive diagnosis of PBTs in LMICs, when compared with high-income countries. While evidence-based policy recommendations may improve the pace of diagnosis, policy makers will need to be cognizant of the unique challenges patients and health care systems face in LMICs.

RESUMEN

BACKGROUND AND OBJECTIVES: Brain tumors have a poor prognosis and a high death rate. Sufficient aftercare is necessary to enhance patient results. But follow-up care provision is fraught with difficulties in low- and middle-income countries (LMICs), where a variety of variables can impede access to care. Therefore, our systematic review aimed to identify challenges to follow-up care for brain tumors and possible solutions in LMICs. METHODS: A thorough search of the literature was performed from the beginning until October 20, 2022, using Google Scholar, PubMed, Scopus, and CINAHL. Studies focusing on the aftercare of brain tumors in LMICs met the inclusion criteria. Two reviewers used the National Surgical, Obstetric, and Anesthesia Plan categories to identify themes, extract relevant data, and evaluate individual articles. After being discovered, these themes were arranged in Microsoft Excel to make reporting and comprehension simpler. RESULTS: A total of 27 studies were included in the review. Among the studies included, the most frequently cited barriers to follow-up care were financial constraints (54%), long-distance travel (42%), and a lack of awareness about the importance of follow-up care (25%). Other challenges included preference for traditional or alternative medications (4%) and high treatment costs (8%). Proposed strategies included implementing mobile clinics (20%), establishing a documentation system (13%), and educating patients about the importance of follow-up care (7%). CONCLUSION: In LMICs, several issues pertaining to personnel, infrastructure, service delivery, financing, information management, and governance impede the provision of follow-up treatment for patients with brain tumors. As established by the suggested techniques found in the literature, addressing these issues will necessitate concurrent action by stakeholders, legislators, health ministries, and government agencies.

RESUMEN

BACKGROUND: Low- and middle-income countries (LMICs) often struggle to provide adequate neurosurgical care due to poor governance and institutional efforts, making access to care difficult. Therefore, our review of literature aims to identify gaps in government, national, and institutional efforts to combat barriers to neurosurgical care of brain tumors in LMICs, to inform future policy and action planning. METHODS: A comprehensive literature search was conducted using PubMed, Scopus, Google Scholar, and CINAHL without language restrictions from inception to October 20, 2022. After screening and data extraction, a thematic analysis based on the National Surgical, Obstetric, and Anesthesia Plan (NSOAP) systematically identified and classified notable themes, which were then quantified and presented as percentages. RESULTS: A total of 12 studies were included in the final analysis. The review highlighted some of the barriers to providing surgical care of brain tumors in LMICs, including political instability (14%), inadequate national budget for healthcare (43%), poor government support (14%), lack of support of hospital management (14%), and no coverage under national insurance plans (14%). Strategies that can be implemented to address the barriers include strengthening the local health system (17%), advocating for health ministry support (33%), developing national treatment guidelines (17%), making neurosurgery a part of the national surgical plan (17%), fostering collaborations across various levels of government (17%), changing national insurance policy to include neurosurgical care (17%), and advocating for more resources and changes in global care (33%). CONCLUSION: Effective governance plays a critical role in addressing challenges as it shapes the availability of resources and policies that affect the quality of care provided. Our study outlines key challenges and strategies reported within literature in an attempt to drive government attention and thereby policy to support the neurosurgical care of brain tumors, particularly in the developing world.

RESUMEN

Background Pakistan has a significant proportion of medical graduates who intend to leave the country for better opportunities abroad, leading to a brain drain. However, the push and pull factors within neurosurgery remain unexplored, emphasizing the need for evaluation to enact policy changes. Materials and Methods We conducted a nationwide survey across 22 College of Physicians and Surgeons of Pakistan accredited neurosurgery training centers in all provinces of Pakistan. SPSS version 26 and STATA 15 were used for data analysis. Results We collected responses from 120 neurosurgery trainees across Pakistan. Trainees were categorized into two groups: those intending to leave (64%) and those intending to stay (36%) in Pakistan. A significant association was observed between the availability of fellowship training in the residents' hospital and the decision to leave or remain in Pakistan ( p = 0.034). About 67.5% of our respondents did not have any publication, and among the intention to leave group, a greater percentage had academic involvement, when compared with the stay group. A significant association ( p = 0.012) was also observed between the decision to leave or remain in Pakistan and the number of publications in nonindexed journals. Conclusion There remains a need for improvement in the standard of training provided by neurosurgery programs across the country. Our study found that disparities in research and academic exposure, as well as the lack of fellowship opportunities, may serve as stimuli for residents to leave Pakistan.

RESUMEN

BACKGROUND AND OBJECTIVES: While early diagnosis of brain tumors is essential for improving prognoses, several challenges prevent early diagnosis of these illnesses in low- and middle-income countries. The objective of this systematic review is to identify and evaluate the barriers and challenges to early detection of brain tumors in Low- and Middle-Income Countries (LMICs), as well as to propose potential solutions. METHOD: A thorough search of the literature was carried out with the aid of multiple databases, including Google Scholar, CINAHL, PubMed, and Scopus. Studies focusing on the early detection of brain tumors in low- and middle-income countries met the inclusion criteria for this review. Articles were screened independently by two reviewers. National Surgical, Obstetric, and Anesthesia plan (NSOAP) framework was used to extract relevant data and develop themes. Microsoft Excel was then used to arrange and analyze these themes. RESULTS: Out of 21 articles included in the final analysis, notable challenges to early detection of brain tumors included healthcare providers' lack of awareness of early signs and symptoms of brain tumors (21%), limited diagnostic facilities (38%), misdiagnosis by healthcare providers (33%) and financial constraints (46%). Potential strategies for addressing these barriers and challenges include educating healthcare providers on early warning signs (50%), improving the early referral system (25%) and establishing local clinical guidelines (19%). CONCLUSION: Significant barriers to early detection persist in LMICs. Collaboration between stakeholders, legislators, health ministries, and governmental organizations is essential for developing and implementing focused interventions, such as establishment of referral pathways and specialized centers, adapting guidelines to local cultural contexts and raising public and professional awareness.

RESUMEN

Limited neurosurgical workforces remain one of the critical problems experienced in low resource settings. Therefore, our study aims to explore and summarize the key challenges to neurosurgical care of brain tumors in terms of workforce in LMICs. A comprehensive literature search was conducted using Scopus, PubMed, CINAHL, and Google Scholar from inception to October 20, 2022. All extracted data were screened independently by 2 reviewers and thematically analyzed. We found and screened 3764 articles, of which 33 studies were included in our final analysis as per our inclusion criteria. Among the studies included, 33% highlighted the limited number of neurosurgeons, 39% emphasized the absence of specialized surgical teams, 7% pointed out a shortage of nursing staff, and 4% noted suboptimal anesthesia teams. The study uncovered the need for improved training programs in neuro-oncology (32%) and neuro-anesthesia (3%), as well as improved collaboration (32%), and multidisciplinary team structures (15%), are essential for tackling these workforce challenges and improving patient outcomes. It is crucial to implement targeted interventions and policy changes to address the barriers to the workforce in providing effective neurosurgical care to patients with brain tumors in developing countries. This might entail capacity building and training programs for healthcare professionals. Policymakers should consider allocating resources and funding for workforce development and making neurosurgical care a priority in healthcare plans.

RESUMEN

BACKGROUND: Making neurosurgical care accessible to a larger portion of the population in low- and middle-income countries (LMICs) is integral due to the high mortality and morbidity associated with brain tumors. However, the high cost of care often makes it financially out of reach for many individuals. Therefore, this review aims to identify barriers to neurosurgical care of brain tumors in terms of financing in LMICs. METHODS: Without restriction to language, a search of the literature was undertaken in a number of databases, including PubMed, Scopus, Google Scholar, and CINAHL, in order to find the most pertinent research involving financing of brain tumors in LMICs. The last day of the search was October 20, 2022. Following screening and data extraction, significant themes were found and categorized using thematic analysis. RESULTS: A total of 28 studies were analyzed in this review. The review highlighted some of the barriers to providing surgical care of brain tumors in LMICs. In the cited studies, surgical expenses (41%), neuroimaging costs (30%), and care-related expenses (33%) were the primary concerns. Addressing these challenges involves cross-border collaboration (23%), transparent financing systems (46%), awake craniotomy (15%), cost-effective/reusable intra-operative supplies (8%), and optimizing resources in healthcare systems (8%). CONCLUSIONS: This study explored barriers and challenges to financing neurosurgical care of brain tumors in LMICs. Government support and transparency in healthcare financing should be prioritized to ensure that all individuals have access to surgical care of brain tumors.

RESUMEN

OBJECTIVE: A meta-analysis was conducted to compare: 1) time from traumatic brain injury (TBI) to the hospital, and 2) time within the hospital to intervention or surgery, by country-level income, World Health Organization region, and healthcare payment system. METHODS: A comprehensive literature search was conducted and followed by a meta-analysis comparing duration of delays (prehospital and intrahospital) in TBI management. Means and standard deviations were pooled using a random effects model and subgroup analysis was performed using R software. RESULTS: Our analysis comprised 95,554 TBI patients from 45 countries. BY COUNTRY-LEVEL INCOME: From 23 low- and middle-income countries, a longer mean time from injury to surgery (862.53 minutes, confidence interval [CI]: 107.42-1617.63), prehospital (217.46 minutes, CI: -27.34-462.25), and intrahospital (166.36 minutes, 95% CI: 96.12-236.60) durations were found compared to 22 high-income countries. BY WHO REGION: African Region had the greatest total (1062.3 minutes, CI: -1072.23-3196.62), prehospital (256.57 minutes [CI: -202.36-715.51]), and intrahospital durations (593.22 minutes, CI: -3546.45-4732.89). BY HEALTHCARE PAYMENT SYSTEM: Multiple-Payer Health Systems had a greater prehospital duration (132.62 minutes, CI: 54.55-210.68) but greater intrahospital delays were found in Single-Payer Health Systems (309.37 minutes, CI: -21.95-640.69). CONCLUSION: Our study concludes that TBI patients in low- and middle-income countries within African Region countries face prolonged delays in both prehospital and intrahospital management compared to high-income countries. Additionally, patients within Single-Payer Health System experienced prolonged intrahospital delays. An urgent need to address global disparities in neurotrauma care has been highlighted.

RESUMEN

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.

RESUMEN

Background: Accurate and precise diagnosis is central to treating central nervous system (CNS) tumors, yet tissue diagnosis is often a neglected focus in low- and middle-income countries (LMICs). Since 2016, the WHO classification of CNS tumors has increasingly incorporated molecular biomarkers into the diagnosis of CNS tumors. While this shift to precision diagnostics promises a high degree of diagnostic accuracy and prognostic precision, it has also resulted in increasing divergence in diagnostic and management practices between LMICs and high-income countries (HICs). Pathologists and laboratory professionals in LMICs lack the proper training and tools to join the molecular diagnostic revolution. We describe the impact of a 7-year long twinning program between Canada and Pakistan on pathology services. Methods: During the study period, 141 challenging cases of pediatric CNS tumors initially diagnosed at Aga Khan University Hospital (AKUH), Karachi, were sent to the Hospital for Sick Children in Toronto, Canada (SickKids), for a second opinion. Each case received histologic review and often immunohistochemical staining and relevant molecular testing. A monthly multidisciplinary online tumor board (MDTB) was conducted to discuss the results with pathologists from both institutions in attendance. Results: Diagnostic discordance was seen in 30 cases. Expert review provided subclassification for 53 cases most notably for diffuse gliomas and medulloblastoma. Poorly differentiated tumors benefited the most from second review, mainly because of the resolving power of specialized immunohistochemical stains, NanoString, and targeted gene panel next-generation sequencing. Collaboration with expert neuropathologists led to validation of over half a dozen immunostains at AKUH facilitating diagnosis of CNS tumors. Conclusions: LMIC-HIC Institutional twinning provides much-needed training and mentorship to pathologists and can help in infrastructure development by adopting and validating new immunohistochemical stains. Persistent unresolved cases indicate that molecular techniques are indispensable in for diagnosis in a minority of cases. The development of affordable alternative molecular techniques may help with these histologically unresolved cases.

RESUMEN

INTRODUCTION: Traumatic brain injury (TBI) accounts for the majority of Uganda's neurosurgical disease burden; however, invasive intracranial pressure (ICP) monitoring is infrequently used. Noninvasive monitoring could change the care of patients in such a setting through quick detection of elevated ICP. PURPOSE: Given the novelty of pupillometry in Uganda, this mixed methods study assessed the feasibility of pupillometry for noninvasive ICP monitoring for patients with TBI. METHODS: Twenty-two healthcare workers in Kampala, Uganda received education on pupillometry, practiced using the device on healthy volunteers, and completed interviews discussing pupillometry and its implementation. Interviews were assessed with qualitative analysis, while quantitative analysis evaluated learning time, measurement time, and accuracy of measurements by participants compared to a trainer's measurements. RESULTS: Most participants (79%) reported a positive perception of pupillometry. Participants described the value of pupillometry in the care of patients during examination, monitoring, and intervention delivery. Commonly discussed concerns included pupillometry's cost, understanding, and maintenance needs. Perceived implementation challenges included device availability and contraindications for use. Participants suggested offering continued education and engaging hospital leadership as implementation strategies. During training, the average learning time was 13.5 minutes (IQR 3.5), and the measurement time was 50.6 seconds (IQR 11.8). Paired t-tests to evaluate accuracy showed no statistically significant difference in comparison measurements. CONCLUSION: Pupillometry was considered acceptable for noninvasive ICP monitoring of patients with TBI, and pupillometer use was shown to be feasible during training. However, key concerns would need to be addressed during implementation to aid device utilization.

RESUMEN

Objective: This study aims to evaluate the immunomodulatory effects of coconut oil extract (COE) in broilers experimentally infected with velogenic Newcastle disease virus (vNDV). Methods: A total of 150 broiler birds (day-old) were equally divided into five study groups i.e., negative control, positive control, COE-1, COE-2, and COE-3. On day 10, broilers of groups COE-1, COE-2, and COE-3 were supplemented with 1, 2, and 3 ml of COE respectively per liter of drinking water for 15 days. On day 13, 0.1ml/bird (10-5.25 ELD50) of vNDV was inoculated in broilers of positive control, COE-1, COE-2, and COE-3 groups intramuscularly. During this study, growth performance, morbidity, and mortality rates of each study group were recorded. The antibody titer against NDV was determined on days 7, 14, 21, 28, and 35. The levels of IgY and IgM were also determined on the 7th, 14th, and 21st days post-SRBC inoculation. On day 33, avian tuberculin was injected between the 1st and 2nd toes of the left side (intradermally) to measure lymphoproliferative responses. On day 35, the phagocytic activity in the blood was assessed through a carbon clearance assay by injecting carbon black ink into the right-wing vein. The visceral organs having gross lesions were also collected for histopathology. Results: The COE significantly improved the growth performance, and lowered the morbidity and mortality rates of broilers. There was a significant rise in antibody titers against NDV and levels of IgY and IgM antibodies against SRBC in COE-supplemented broilers. The lymphoproliferative response and phagocytic activity were also enhanced. Among COE-supplemented groups, the broilers of the COE-3 group showed a significant increase in growth performance and boosted immune defense. Conclusions: Coconut oil extract has the potential to boost the growth performance and immune status of broilers. It can be used effectively as a feed additive and alternative to antibiotics to prevent the spread of infectious poultry pathogens.

RESUMEN

BACKGROUND: Pakistan grapples with the issue of an inadequate neurosurgery workforce but the reasons for such a disparity remain uncertain. Previous studies have highlighted how various factors including medical school experiences have an impact on career choice, but no study has delved into the impact of medical school exposure among Pakistani medical students, especially for the field of neurosurgery. This study aims to evaluate the impact of neurosurgery exposure, mentorship, and interest groups on medical students' decision to pursue neurosurgery. METHODS: A national cross-sectional survey was conducted in Pakistan, collecting data from medical students, interns, and medical officers over a one-month period. Ethical approval was obtained from the Ethical Review Committee at Aga Khan University, Pakistan. The data was analyzed using SPSS version 26. RESULTS: Out of 2618 participants, 38.0% were male and 62.0% were female, with an average age of 21.82 years (± 2.65). Among them, only 358 (13.6%) were interested in pursuing neurosurgery as a career, while the remaining 2,260 (86.3%) were not. More females (58.9%) than males (41.1%) expressed interest in pursuing neurosurgery as their intended career. Most medical students interested in pursuing neurosurgery were in the early years of their medical school (1st Year: 19.6%, 2nd Year: 26.0%, 3rd Year: 20.9%). In our study, students from public sector institutions (52.2%) showed more interest in neurosurgery as a career choice compared to those from private sector institutions (44.1%). The main deterrents for choosing neurosurgery were intense training (42.2%), work-life balance (39.9%), limited residency slots (56.7%), medical knowledge (34.1%), and surgical skills (36.6%). CONCLUSION: This study highlights the need for increased student engagement to inculcate the decision to pursue neurosurgery among medical students in Pakistan. A significant gap is highlighted, with the majority of interested students in early years. Public sector students show higher interest than their private sector counterparts. However, barriers like intense training, limited residency slots, and work-life balance concerns influence career choice. Targeted interventions like mentorship programs are crucial for fostering future neurosurgeons and advancing patient care and research. By addressing the identified disparities in experiences and promoting a supportive educational environment, it is possible to cultivate a future generation of skilled and dedicated neurosurgeons who can contribute to advancements in patient care and research in the field.

RESUMEN

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.
