Smoking-Related Disease Impact in the Eastern Mediterranean Region: A Comprehensive Assessment Using Global Burden of Disease Data.

BACKGROUND: Smoking remains a significant risk factor for numerous health issues, including lung cancer, chronic obstructive pulmonary disease, ischemic heart disease, stroke, and respiratory infections. This study investigates the burden of tobacco-related diseases in the Middle East and North Africa (MENA) region. METHODS: Utilizing the GBD data, we examined the risk of smoking and second-hand smoke exposure and their related causes of death and disability in the 22 MENA countries. Smoking prevalence and disease burden data were analyzed with estimates reported as age-standardized rates. RESULTS: Tobacco abuse accounted for 14.5% of all deaths and 23.2% of deaths tied to known risk factors, with an age-standardized death rate of 110.8 per 100,000. Cardiovascular diseases were the primary cause of smoking-related deaths and DALYs, representing 53.4% of all deaths and 50.3% of all DALYs. This was followed by neoplasms (24.6% of all deaths and 20.3% of all DALYs), chronic respiratory diseases(12.4% of all deaths and 11.9% of all DALYs), and respiratory infections and tuberculosis(4% of all deaths and 3.4% of all DALYs). Second-hand smoking caused 20.5% of tobacco-related deaths and 21.5% of tobacco-related DALYs, disproportionately affecting younger individuals. An increasing disease burden was observed in Lebanon, Turkey, Syria, Tunisia, UAE, and Libya, and declining rates were most evident in Oman and Qatar. CONCLUSION: Our study emphasizes the impact of smoking on cardiovascular disease, the primary cause of smoking-related mortality and morbidity in the MENA region. Our findings highlight the urgent need for effective tobacco control policies and interventions.

The role of neurosurgery in advancing pediatric CNS tumor care worldwide.

Introduction: There is substantial inequity in survival outcomes for pediatric brain tumor patients residing in high-income countries (HICs) compared to low- and middle-income countries (LMICs). To address disparities in pediatric cancer survival, the World Health Organization (WHO) established the Global Initiative for Childhood Cancer (GICC) to expand quality care for children with cancer. Research question: To provide an overview of pediatric neurosurgical capacity and detail the burden of neurosurgical diseases impacting children. Material and methods: A narrative review of the current context of global pediatric neurosurgical capacity as it relates to neurooncology and other diseases relevant to children. Results: In this article, we provide an overview of pediatric neurosurgical capacity and detail the burden of neurosurgical diseases impacting children. We highlight concerted advocacy and legislative efforts aimed at addressing unmet neurosurgical needs in children. Finally, we discuss the potential implications of advocacy efforts on treating pediatric CNS tumors and outline strategies to improve global outcomes for children with brain tumors worldwide in the context of the WHO GICC. Discussion and conclusion: With both global pediatric oncology and neurosurgical initiatives converging on the treatment of pediatric brain tumors, significant strides toward decreasing the burden of pediatric neurosurgical diseases will hopefully be made.

Pediatric Neurosurgical Capacity for the Care of Children With CNS Tumors Worldwide: A Cross-Sectional Assessment.

PURPOSE: Efforts to address inequities in the treatment of pediatric CNS tumors and the burden of childhood cancer globally have prompted the designation of low-grade glioma as one of six index cancers for the World Health Organization Global Initiative for Childhood Cancer. Understanding the importance of neurosurgical interventions and evaluating pediatric neurosurgical capacity may identify critical interventions to improve outcomes for children with low-grade glioma and other CNS tumors. METHODS: An online, cross-sectional survey assessing pediatric neurosurgical practice and capacity was distributed to members of the International Society of Pediatric Neurosurgery. The survey included 36 items covering domains including patient volume, available infrastructure, scope of practice, case distribution, and multidisciplinary care. RESULTS: Responses from 196 individuals from 61 countries, spanning all WHO regions, were included. Ninety-six (49.0%) were from high-income countries, 57 (29.1%) were from upper-middle-income countries, 42 (21.4%) were from lower-middle-income countries (LMICs), and 1 was (0.5%) from a low-income country. Most respondents had a catchment population of ≥ 1 million and indicated the availability of basic neurosurgical resources such as a dedicated neurosurgical operating theater and surgical microscope. The presence of a neurosurgical intensive care unit, inpatient rehabilitation services, and infection monitoring showed similar availability across country groups. Quantitative scoring of 13 infrastructure and service items established that fewer resources were available in low-income countries/LMICs and upper-middle-income countries compared with high-income countries. The volume of pediatric CNS tumor cases and case distribution did not vary according to World Bank country groups. CONCLUSION: This study provides a comprehensive evaluation of pediatric neurosurgical capacity across the globe, establishing variability of resources on the basis of the country income level. Our findings suggest that pediatric neurosurgeons in LMICs may benefit from key neurosurgical instrumentation and increased support for multidisciplinary brain tumor programs and childhood cancer research efforts.

Assessment of Retinoblastoma Capacity in the Middle East, North Africa, and West Asia Region.

PURPOSE: We aimed to evaluate the capacity to treat retinoblastoma in the Middle East, North Africa, and West Asia region. METHODS: A Web-based assessment that investigated retinoblastoma-related pediatric oncology and ophthalmology infrastructure and associated capacity at member institutions of the Pediatric Oncology East and Mediterranean group was distributed. Data were analyzed in terms of availability, location, and confidence of use for each resource needed for the management of retinoblastoma. Resources were categorized by diagnostics, focal therapy, chemotherapy, advanced treatment, and supportive care. Responding institutions were further divided into an asset-based tiered system. RESULTS: In total, responses from 23 institutions were obtained. Fifteen institutions reported the availability of an ophthalmologist, 12 of which held primary off-site appointments. All institutions reported the availability of a pediatric oncologist and systemic chemotherapy A significant portion of available resources was located off site. Green laser was available on site at seven institutions, diode laser at six institutions, cryotherapy at 12 institutions, and brachytherapy at nine institutions. There existed marked disparity between the availability of some specific ophthalmic resources and oncologic resources. CONCLUSION: The assessment revealed common themes related to the treatment of retinoblastoma in low- and- middle-income countries, including decentralization of care, limited resources, and lack of multidisciplinary care. Resource disparities warrant targeted intervention in the Middle East, North Africa, and West Asia region to advance the management of retinoblastoma in the region.

Treatment burden and long-term health deficits of patients with low-grade gliomas or glioneuronal tumors diagnosed during the first year of life.

BACKGROUND: Low-grade gliomas (LGGs) and low-grade glioneuronal tumors (LGGNTs) diagnosed during the first year of life carry unique clinical characteristics and challenges in management. However, data on the treatment burden, outcomes, and morbidities are lacking. METHODS: A retrospective study of LGGs and LGGNTs diagnosed in patients younger than 12 months at St. Jude Children's Research Hospital (1986-2015) was conducted. RESULTS: For the 51 patients (including 31 males), the mean age at diagnosis was 6.47 months (range, 0.17-11.76 months), and the mean follow-up period was 11.8 years (range, 0.21-29.19 years). Tumor locations were hypothalamic/optic pathway (61%), hemispheric (12%), brainstem (12%), cerebellar (8%), and spinal (8%). There were 41 patients with histological diagnoses: 28 had World Health Organization grade 1 tumors, 6 had grade 2 tumors, and 7 had an LGG/LGGNT not definitively graded. Forty-one patients required an active intervention at diagnosis. Throughout their treatment course, 41 patients eventually underwent tumor-directed surgeries (median, 2 surgeries; range, 1-6), 39 received chemotherapy (median, 2 regimens; range, 1-13), and 21 received radiotherapy. Forty patients experienced disease progression (median, 2 progressions; range, 1-18). Ten patients died of progression (n = 5), malignant transformation (n = 2), a second cancer (n = 2), or a shunt infection (n = 1). The 10-year overall survival, progression-free survival, and radiation-free survival rates were 85% ± 5.3%, 16.9% ± 5.3%, and 51.2% ± 7.5%, respectively. Forty-nine patients experienced health deficits (eg, endocrinopathies, obesity, seizures, visual/hearing impairments, neurocognitive impairments, and cerebrovascular disease). Predictors of progression and toxicities were defined. CONCLUSIONS: Infantile LGG/LGGNT is a chronic, progressive disease universally associated with long-term morbidities and requires multidisciplinary intervention.

SIOP PODC adapted treatment recommendations for standard-risk medulloblastoma in low and middle income settings.

Effective treatment of children with medulloblastoma requires a functioning multi-disciplinary team with adequate neurosurgical, neuroradiological, pathological, radiotherapy and chemotherapy facilities and personnel. In addition the treating centre should have the capacity to effectively screen and manage any tumour and treatment-associated complications. These requirements have made it difficult for many low and middle-income countries (LMIC) centres to offer curative treatment. This article provides management recommendations for children with standard-risk medulloblastoma (localised tumours in children over the age of 3-5 years) according to the level of facilities available.

Web-based survey of resources for treatment and long-term follow-up for children with brain tumors in developing countries.

INTRODUCTION: Information about pediatric survivors of brain tumors in developing countries is scant. PURPOSE: In this study, we aimed to investigate the availability of resources for treatment and long-term follow-up of children with central nervous system tumors in developing countries. MATERIALS AND METHODS: A web-based questionnaire on available services and follow-up of brain tumor survivors was posted at www.cure4kids.org , and registered users were invited to participate. RESULTS: A total of 140 evaluable responses from developing countries (n = 103) and high-income countries (n = 37) were obtained. There was a significant correlation between gross national income and the availability of services for treatment and follow-up and between patient load and the availability of some services. CONCLUSION: The resources for treatment and long-term follow-up of children with brain tumors need to be improved in developing countries.

Dysembryoplastic neuroepithelial tumors and cognitive outcome: cure at a price?

BACKGROUND: Dysembryoplastic neuroepithelial tumors (DNETs) are benign glioneuronal tumors that occur in children. These tumors are characterized by seizures, lack of neurologic deficits, and a seemingly benign course after resection. METHODS: A retrospective review was conducted of data relating to 11 children diagnosed with DNETs between January 1988 and December 2007 at St. Jude Children's Research Hospital. This report documented the clinical features, neurocognitive function, and treatment outcomes in this institutional series. RESULTS: The patient cohort included 8 boys and 3 girls (median age at diagnosis, 10 years); all patients presented with seizures: 4 complex partial, 3 generalized tonic-clonic, 2 absence, 1 partial simple, and 1 not classified. Of the 11 patients, 1 died of cardiac fibrosis, and tumors recurred or progressed in 4 (36%) patients. Seizure control was achieved in all patients but 1. Of the 9 patients who completed neuropsychologic testing, only 3 (33%) functioned at or above the expected level of same-age peers. CONCLUSIONS: The high recurrence and progression rates of DNETs and the high rate of abnormal neurocognitive test results noted in the current study highlight the need for regular follow-up and appropriate academic counseling of children with these tumors.
