Balloon-mounting stent versus balloon angioplasty for intracranial arterial stenosis: A systematic review and meta-analysis. J Stroke Cerebrovasc Dis 2024; 33:107631. [PMID: 38331010 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 02/01/2024] [Accepted: 02/05/2024] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND Intracranial artery atherosclerotic stenosis (ICAS) is a major cause of stroke, especially in Asian countries. Current treatment options, including balloon-mounted stent (BMS) and balloon angioplasty (BA), lack sufficient evidence to determine a preferred approach. This systematic review and meta-analysis aimed to compare the efficacy and safety of BMS and BA in treating ICAS. METHODS Following PRISMA 2020 guidelines, we conducted a comprehensive search in PubMed, Web of Science, and Scopus up to December 1, 2023. Eligible studies compared BMS with BA in patients diagnosed with ICAS. Primary outcomes included the success rate and occurrence of stroke (ischemic or hemorrhagic). Secondary outcomes were perforator occlusion, in-stent thrombosis, death, and restenosis. Statistical analysis was conducted using R software version 4.3.1, employing a random-effects model. RESULTS Five high-quality studies involving 707 patients (515 males, 192 females) were included. BMS had a significantly higher success rate compared to BA (Risk Ratio [RR]: 1.13; CI: 1.03 to 1.24, p < 0.01; I2 = 14 %). The overall risk for stroke (ischemic and hemorrhagic) was significantly higher in BMS (RR: 2.97; CI: 1.32 to 6.67, p < 0.01; I2 = 0 %). However, no significant difference was found between BMS and BA regarding ischemic stroke (RR: 2.33; CI: 0.80 to 6.74, p = 0.12; I2 = 0 %). Additionally, no significant differences were observed in terms of perforator occlusion, in-stent thrombosis, dissection, minor and major strokes, and mortality rates. BMS was associated with a lower risk of restenosis (RR: 0.31; 95 % CI: 0.12 to 0.83, p = 0.02; I2 = 0 %). CONCLUSION Our results indicate that BMS might be associated with higher success and lower restenosis rates than BA in the treatment of ICAS but with an increased overall risk of stroke. No significant differences were observed in ischemic stroke, perforator occlusion, in-stent thrombosis, dissection, minor and major strokes, and mortality rates. The choice of treatment should consider these findings, alongside the technical challenges and desired angiographic outcomes. Future randomized controlled trials are necessary to further elucidate these results.

The impact of regular aspirin use on aneurysm recanalization rates after endovascular coiling. J Neurosurg 2024:1-6. [PMID: 38608309 DOI: 10.3171/2024.1.jns232726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 01/26/2024] [Indexed: 04/14/2024]
Abstract
OBJECTIVE Intracranial aneurysms (IAs) pose a significant health risk, often leading to subarachnoid hemorrhage and severe neurological outcomes. Endovascular coiling has been a principal treatment method, but it comes with the challenge of high recanalization rates. Aspirin has recently emerged as a potential agent to reduce these rates. In this study, the authors aimed to investigate the impact of regular aspirin use on aneurysm recanalization rates following endovascular coiling in a 10-year single-institution study. METHODS A retrospective analysis was conducted on a dataset of 2236 aneurysms treated by a single neurosurgeon over a period of 10 years. The primary outcome measure was aneurysm recanalization, defined by a change in the Raymond-Roy Occlusion Classification of at least one grade. RESULTS A total of 525 aneurysms were coiled, 109 of which involved patients who reported regular use of aspirin. The recanalization rate was significantly lower in the aspirin group (9.2%) compared with the control group (23.6%) (OR 0.33, 95% CI 0.15-0.66; p = 0.001). On analysis of the specific mechanisms of recanalization, aneurysm sac growth was less frequent in the aspirin group (5.5%) compared with the control group (18%) (OR 0.265, 95% CI 0.09-0.63; p = 0.002). Additionally, patients in the control group had a higher retreatment rate (18%) than patients in the aspirin group (5.5%) (OR 0.265, 95% CI 0.09-0.63; p = 0.002). CONCLUSIONS Regular use of aspirin appears to be associated with reduced rates of aneurysm recanalization after endovascular coiling. However, caution is advised in interpretation of these results given the retrospective nature of this study. Further randomized controlled trials are needed to confirm these findings.

Efficacy and safety of tranexamic acid in the management of chronic subdural hematoma: a systematic review and meta-analysis. J Neurosurg 2024:1-10. [PMID: 38579356 DOI: 10.3171/2024.1.jns232463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 01/12/2024] [Indexed: 04/07/2024]
Abstract
OBJECTIVE Chronic subdural hematoma (CSDH) is a prevalent neurosurgical condition, particularly among the elderly. Various treatment options exist, but recurrence rates remain high. This systematic review and meta-analysis aims to assess the efficacy and safety of tranexamic acid (TXA) in the management of CSDH. METHODS The authors conducted a comprehensive literature search adhering to the 2020 PRISMA guidelines, involving three primary databases (Scopus, PubMed, and Web of Science) that were searched for articles compiled from inception until October 20, 2023. The primary outcome was recurrence of CSDH, and secondary outcomes included complications and SDH volume following TXA treatment. The mean difference and odds ratios with 95% confidence intervals were calculated using the random-effects model. RESULTS A total of 5 studies, involving 643 patients in the TXA group and 736 patients in the non-TXA group, met the inclusion criteria. The meta-analysis revealed that TXA use led to a significantly lower CSDH recurrence (OR 0.35, 95% CI 0.23-0.53; p < 0.01) without increasing complications (OR 1.84, 95% CI 0.43-7.95; p = 0.42). Additionally, TXA users had a significantly lower CSDH volume compared to the non-TXA group at 3-month follow-up (mean difference -4.56, 95% CI -8.76 to -0.36; p = 0.03). CONCLUSIONS The findings suggest that TXA might be a promising agent for reducing the risk of CSDH recurrence without elevating the risk of complications. However, these results should be interpreted cautiously due to the limited number of studies included and the methodological heterogeneity. Further large-scale randomized controlled trials are needed to confirm these findings.

Cognitive outcomes following aneurysmal subarachnoid hemorrhage: Rehabilitation strategies. World Neurosurg X 2024; 22:100341. [PMID: 38450248 PMCID: PMC10914592 DOI: 10.1016/j.wnsx.2024.100341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 02/21/2024] [Indexed: 03/08/2024] Open
Abstract
Despite decreases in mortality rate, the treatment of cognitive deficits following aneurysmal subarachnoid hemorrhage (aSAH) remains a serious challenge for clinicians and survivors alike. Deficits in executive function, language, and memory prevent more than half of survivors from returning to their previous level of work and put a tremendous amount of stress on the individual and their family. New therapies are needed for survivors of aSAH in order to improve cognitive outcomes and quality of life. The aim of this review is to discuss the prevalence and contributing factors of cognitive deficits following aSAH, as well as areas for therapeutic intervention. Due to the limited research on cognitive rehabilitative strategies for aSAH, a literature search of traumatic brain injury (TBI) was used to explore therapies with the potential to improve cognitive outcomes in aSAH. Across cognitive domains, existing rehabilitative and pharmacotherapeutic strategies for TBI show promise to be useful for survivors of aSAH. However, further study of these therapies in addition to consistent assessment of cognitive deficits are required to determine their efficacy in survivors of aSAH.

Antithrombotic Therapy in Cerebral Cavernous Malformations: A Systematic Review, Meta-Analysis, and Network Meta-Analysis. J Am Heart Assoc 2024; 13:e032910. [PMID: 38471833 PMCID: PMC11010038 DOI: 10.1161/jaha.123.032910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 01/04/2024] [Indexed: 03/14/2024]
Abstract
BACKGROUND Cerebral cavernous malformations are complex vascular anomalies in the central nervous system associated with a risk of intracranial hemorrhage. Traditional guidelines have been cautious about the use of antithrombotic therapy in this patient group, citing concerns about potential bleeding risk. However, recent research posits that antithrombotic therapy may actually be beneficial. This study aims to clarify the association between antithrombotic therapy, including antiplatelet and anticoagulant medications, and the risk of intracranial hemorrhage in patients with cerebral cavernous malformations. METHODS AND RESULTS A comprehensive literature search was conducted in PubMed, Web of Science, and Scopus databases, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Nine single-center, nonrandomized cohort studies involving 2709 patients were included. Outcomes were analyzed using random-effects model, and a network meta-analysis was conducted for further insight. Of the 2709 patients studied, 388 were on antithrombotic therapy. Patients on antithrombotic therapy had a lower risk of presenting with intracranial hemorrhage (odds ratio [OR], 0.56 [95% CI, 0.45-0.7]; P<0.0001). In addition, the use of antithrombotic therapy was associated with lower risk of intracranial hemorrhage from a cerebral cavernous malformation on follow-up (OR, 0.21 [95% CI, 0.13-0.35]; P<0.0001). A network meta-analysis revealed a nonsignificant OR of 0.73 (95% CI, 0.23-2.56) when antiplatelet therapy was compared with anticoagulant therapy. CONCLUSIONS Our study explores the potential benefits of antithrombotic therapy in cerebral cavernous malformations. Although the analysis suggests a possible role for antithrombotic agents, it is critical to note that the evidence remains preliminary. Fundamental biases in study design, such as ascertainment and assignment bias, limit the weight of our conclusions. Therefore, our findings should be considered hypothesis-generating and not definitive for clinical practice change.

Comparative outcomes of middle meningeal artery embolization with statins versus embolization alone in the treatment of chronic subdural hematoma: a systematic review and meta-analysis. Neurosurg Rev 2023; 46:262. [PMID: 37783962 DOI: 10.1007/s10143-023-02165-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 09/20/2023] [Accepted: 09/24/2023] [Indexed: 10/04/2023]
Abstract
Chronic subdural hematoma (cSDH) is common among the elderly, with surgical evacuation as a prevalent treatment, facing recurrence rates up to 30%. Recently, middle meningeal artery embolization (MMAE) has emerged as a promising approach, offering reduced treatment failures and recurrence rates. Additionally, statins, known for their anti-inflammatory properties, have been considered as a potential adjunctive or sole treatment for cSDH. However, the combination of MMAE with statins remains understudied. This systematic review and meta-analysis aims to evaluate the comparative outcomes of MMAE with statins versus MMAE alone in the treatment of cSDH. A comprehensive systematic search of the PubMed, Web of Science, and SCOPUS databases was conducted. Inclusion criteria were: studies published in English between the dates of inception of each database and August 2023, studies comparing the treatment of cSDH with either MMAE + statin or MMAE alone were included. Main outcome measures were complete resolution of the hematoma at follow-up and the recurrence rates. Two studies comprising 715 patients were included; 408 patients underwent MMAE + statin; and 307 underwent MMAE alone. MMAE + statin was not significantly superior to MMAE alone in achieving complete resolution of the hematoma at follow-up (RR: 0.99; CI: 0.91 to 1.07, P = 0.84), nor was it a significant difference in rates of recurrence (RR: 1.35; CI: 0.83 to 2.17, P = 0.21) between the two groups. MMAE + statin did not demonstrate significant superiority over MMAE alone for achieving complete resolution and decreasing the recurrence rates in cSDH patients. Further research with larger, randomized studies may be required to fully elucidate the potential synergistic effects of MMAE and statins in this patient population.

Abstract
OBJECTIVE Despite advances in the nonsurgical management of cerebrovascular atherosclerotic steno-occlusive disease, approximately 15-20% of patients remain at high risk for recurrent ischemia. The benefit of revascularization with flow augmentation bypass has been demonstrated in studies of Moyamoya vasculopathy. Unfortunately, there are mixed results for the use of flow augmentation in atherosclerotic cerebrovascular disease. We conducted a study to examine the efficacy and long term outcomes of superficial temporal artery to middle cerebral artery (STA-MCA) bypass in patients with recurrent ischemia despite optimal medical management. METHODS A single-institution retrospective review of patients receiving flow augmentation bypass from 2013-2021 was conducted. Patients with non-Moyamoya vaso-occlusive disease (VOD) who had continued ischemic symptoms or strokes despite best medical management were included. The primary outcome was time to post-operative stroke. Time from cerebrovascular accident to surgery, complications, imaging results, and modified Rankin Scale (mRS) scores were aggregated. RESULTS Twenty patients met inclusion criteria. The median time from cerebrovascular accident to surgery was 87 (28-105.0) days. Only one patient (5%) had a stroke at 66 days post-op. One (5%) patient had a post-operative scalp infection, while 3 (15%) developed post-operative seizures. All 20 (100%) bypasses remained patent at follow-up. The median mRS score at follow up was significantly improved from presentation from 2.5 (1-3) to 1 (0-2), P = .013. CONCLUSIONS For patients with high-risk non-Moyamoya VOD who have failed optimal medical therapy, contemporary approaches to flow augmentation with STA-MCA bypass may prevent future ischemic events with a low complication rate.

Abstract
AbstractThe sudden onset of severe traumatic brain injury (sTBI) is an event suffered by millions of individuals each year. Regardless of this frequency in occurrence, accurate prognostication remains difficult to achieve among physicians. There are many variables that affect this prognosis. Physicians are expected to assess the clinical indications of the brain injury while considering other factors such as patient quality of life, patient preferences, and environmental context. However, this lack of certainty in prognosis can ultimately affect treatment recommendations and prompt clinical ethical issues at the bedside, as it leaves room for physician bias and interpretation. In this article, we introduce data on neurosurgeon values that may shed light on the process physicians and patients involved in sTBI undergo. In doing so, we highlight the many nuances in decision-making for patients suffering from sTBI and discuss potential solutions to better patient-physician or surrogate-physician interactions.

Abstract
In recent years, physicians and institutions have come to recognize the increasing opioid epidemic in the United States, thus prompting a dramatic shift in opioid prescribing patterns. The lack of well-studied alternative treatment regimens has led to a substantial burden of opioid addiction in the United States. These forces have led to a huge economic burden on the country. The spine surgery population is particularly high risk for uncontrolled perioperative pain, because most patients experience chronic pain preoperatively and many patients continue to experience pain postoperatively. Overall, there is a large incentive to better understand comprehensive multimodal pain management regimens, particularly in the spine surgery patient population. The goal of this review is to explore trends in pain symptoms in spine surgery patients, overview the best practices in pain medications and management, and provide a concise multimodal and behavioral treatment algorithm for pain management, which has since been adopted by a high-volume tertiary academic medical center.

Abstract
Importance There are limited data on which factors affect the critical and complex decision to withdraw life-supporting treatment (LST) in patients with severe traumatic brain injury (sTBI). Objective To determine demographic and clinical factors associated with the decision to withdraw LST in patients with sTBI. Design, Setting, and Participants This retrospective analysis of inpatient data from more than 825 trauma centers across the US in the American College of Surgeons Trauma Quality Improvement Program database from January 2013 to December 2015 included adult patients with sTBI and documentation of a decision regarding withdrawal of LST (WLST). Data analysis was conducted in September 2019. Main Outcomes and Measures Factors associated with WLST in sTBI. Results A total of 37931 patients (9817 women [25.9%]) were included in the multivariable analysis; 7864 (20.7%) had WLST. Black patients (4806 [13.2%]; odds ratio [OR], 0.66; 95% CI, 0.59-0.72; P < .001) and patients of other race (4798 [13.2%]; OR, 0.83; 95% CI, 0.76-0.91; P < .001) were less likely than white patients (26 864 [73.7%]) to have WLST. Patients from hospitals in the Midwest (OR, 1.12; 95% CI, 1.04-1.20; P = .002) or Northeast (OR, 1.23; 95% CI, 1.13-1.34; P < .001) were more likely to have WLST than patients from hospitals in the South. Patients with Medicare (OR, 1.55; 95% CI, 1.43-1.69; P < .001) and self-pay patients (OR, 1.36; 95% CI, 1.25-1.47; P < .001) were more likely to have WLST than patients with private insurance. Older patients and those with lower Glasgow Coma Scale scores, higher Injury Severity Scores, or craniotomy were generally more likely to have WLST. Withdrawal of LST was more likely for patients with functionally dependent health status (OR, 1.30; 95% CI, 1.08-1.58; P = .01), hematoma (OR, 1.19; 95% CI, 1.12-1.27; P < .001), dementia (OR, 1.29; 95% CI, 1.08-1.53; P = .004), and disseminated cancer (OR, 2.82; 95% CI, 2.07-3.82; P < .001) than for patients without these conditions. Conclusions and Relevance Withdrawal of LST is common in sTBI and socioeconomic factors are associated with the decision to withdraw LST. These results highlight the many factors that contribute to decision-making in sTBI and demonstrate that in a complex and variable disease process, variation based on race, payment, and region presents as a potential challenge.

Abstract
Unruptured intracranial saccular aneurysms occur in 3-5% of the general population. As the use of diagnostic medical imaging has steadily increased over the past few decades with the increased availability of computed tomography (CT) and magnetic resonance imaging (MRI), so has the detection of incidental aneurysms. The management of an unruptured intracranial saccular aneurysm is challenging for both patients and physicians, as the decision to intervene must weigh the risk of rupture and resultant subarachnoid hemorrhage against the risk inherent to the surgical or endovascular procedure. The purpose of this paper is to provide an overview of factors to be considered in the decision to offer treatment for unruptured intracranial aneurysms in adults. In addition, we review aneurysm and patient characteristics that favor surgical clipping over endovascular intervention and vice versa. Finally, the authors propose a novel, simple, and clinically relevant algorithm for observation versus intervention in unruptured intracranial aneurysms based on the PHASES scoring system.

Abstract
Objective To summarize current evidence on the impacts of child labor on physical and mental health. Methods We searched PubMed and ScienceDirect for studies that included participants aged 18 years or less, conducted in low- and middle-income countries (LMICs), and reported quantitative data. Two independent reviewers conducted data extraction and assessment of study quality. Results A total of 25 studies were identified, the majority of which were cross-sectional. Child labor was found to be associated with a number of adverse health outcomes, including but not limited to poor growth, malnutrition, higher incidence of infectious and system-specific diseases, behavioral and emotional disorders, and decreased coping efficacy. Quality of included studies was rated as fair to good. Conclusion and recommendations Child labor remains a major public health concern in LMICs, being associated with adverse physical and mental health outcomes. Current efforts against child labor need to be revisited, at least in LMICs. Further studies following a longitudinal design, and using common methods to assess the health impact of child labor in different country contexts would inform policy making.

Abstract
BACKGROUND Surgical decision-making in severe traumatic brain injury (TBI) is complex. Neurosurgeons weigh risks and benefits of interventions that have the potential to both maximize the chance of recovery and prolong suffering. Inaccurate prognostication can lead to over- or under-estimation of outcomes and influence treatment recommendations. OBJECTIVE To evaluate the impact of evidence-based risk estimates on neurosurgeon treatment recommendations and prognostic beliefs in severe TBI. METHODS In a survey-based randomized experiment, a total of 139 neurosurgeons were presented with two hypothetical patient with severe TBI and subdural hematoma; the intervention group received additional evidence-based risk estimates for each patient. The main outcome was neurosurgeon treatment recommendation of non-surgical management. Secondary outcomes included prediction of functional recovery at six months. RESULTS In the first patient scenario, 22% of neurosurgeons recommended non-surgical management and provision of evidence-based risk estimates increased the propensity to recommend non-surgical treatment (odds ratio [OR]: 2.81, 95% CI: 1.21-6.98; p = 0.02). Neurosurgeon prognostic beliefs of 6-month functional recovery were variable in both control (median 20%, IQR: 10%-40%) and intervention (30% IQR: 10%-50%) groups and neurosurgeons were less likely to recommend non-surgical management when they believed prognosis was favorable (odds ratio [OR] per percentage point increase in 6-month functional recovery: 0.97, 95% confidence interval [CI]: 0.95-0.99). The results for the second patient scenario were qualitatively similar. CONCLUSIONS Our findings show that the provision of evidence-based risk predictions can influence neurosurgeon treatment recommendations and prognostication, but the effect is modest and there remains large variability in neurosurgeon prognostication.

Abstract
BACKGROUND Pain control is strongly correlated with the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) quality-of-care domains and overall hospital experience. Prior research implicates several factors in the variability of patients' pain management satisfaction scores, including but not limited to racial diversity, ethnic diversity, gender, socioeconomic status, and other cultural factors. OBJECTIVE In this study, we examined responses to the HCAHPS survey in order to assess factors associated with patient-reported experiences of pain management. STUDY DESIGN The study design involved a retrospective analysis of patient survey responses. SETTING The research took place at a university-affiliated tertiary hospital. METHODS The study was conducted in a university-affiliated tertiary hospital. Records for adult patients discharged between October 2015 and June 2017 were included. We obtained all patient responses to the HCAHPS pain management questions. We then performed a systematic statistical analysis to evaluate interactions between demographic factor variables and responses to the HCAHPS pain management questions. RESULTS Between October 2015 and June 2017, 107,287 patients were discharged from the hospital. Of these, 13,026 of the respondents answered at least one of the HCAHPS pain management questions. Among HCAHPS pain-domain respondents, "Hispanic" and "Black or African American" respondents are more likely to report successful Pain Control when compared to "Not Hispanic" and "Caucasian/White," respectively (odds ratios [ORs] 1.60, 1.22). Additionally, among women, "Black or African American" respondents are more likely to report positive Staff Helpfulness than "Caucasian/White" respondents (OR 1.38).However, we also identified corresponding associations among HCAHPS pain-question responding and patient race/ethnicity: "Hispanic" and "Black/African American" patients were each less likely to respond to the HCAHPS pain questions (ORs 2.03, 2.74). LIMITATIONS The primary limitation to this study was nonresponse bias; nevertheless, this is likely to be similar to bias experienced at other institutions. Additionally, this is a single institution study; however, given that the institution has a very large catchment area, we believe the results could be generalized to other settings. CONCLUSION Response rates and responses to HCAHPS pain questions vary by race/ethnicity and sex. It appears likely that Hispanic and Black/African American patients underreport negative experiences. As HCAHPS surveys are used to inform decision-making within the US health care system, demographic biases in the survey data could lead to biases in care and resource allocation. KEY WORDS Pain, HCAHPS, patient reported outcome measures, patient satisfaction, ethnicity, race.

Abstract
OBJECTIVE In addition to the rising burden of surgical disease globally, infrastructure and human resources for health remain a great challenge for low- and middle-income countries, especially in Uganda. In this study, the authors aim to explore the trends of neurosurgical care at a regional referral hospital in Uganda and assess the long-term impact of the institutional collaboration between Mulago National Referral Hospital and Duke University. METHODS An interrupted time series is a quasi-experimental design used to evaluate the effects of an intervention on longitudinal data. The authors applied this design to evaluate the trends in monthly mortality rates for neurosurgery patients at Mbarara Regional Referral Hospital (MRRH) from March 2013 to October 2015. They used segmented regression and autoregressive integrated moving average models for the analysis. RESULTS Over the study timeframe, MRRH experienced significant increases in referrals received (from 117 in 2013 to 211 in 2015), neurosurgery patients treated (from 337 in 2013 to 625 in 2015), and operations performed (from 61 in 2013 to 173 in 2015). Despite increasing patient volumes, the hospital achieved a significant reduction in hospital mortality during 2015 compared to prior years (p value = 0.0039). CONCLUSIONS This interrupted time series analysis study showed improving trends of neurosurgical care in Western Uganda. There is a steady increase in volume accompanied by a sharp decrease in mortality through the years. Multiple factors are implicated in the significant increase in volume and decrease in mortality, including the addition of a part-time neurosurgeon, improvement in infrastructure, and increased experience. Further in-depth prospective studies exploring seasonality and long-term outcomes are warranted.

Abstract
OBJECTIVE Causes, clinical presentation, management, and outcomes of chronic subdural hematoma (CSDH) in low- and middle-income countries are not well characterized in the literature. Knowledge regarding these factors would be beneficial in the development and implementation of effective preventive and management measures for affected patients. The authors conducted a study to gain a better understanding of these factors in a low-income setting. METHODS This prospective study was performed at Mbarara Regional Referral Hospital (MRRH) in Uganda between January 2014 and June 2017. Patients of any age who presented and were diagnosed with CSDH during the aforementioned time period were included in the study. Variables were collected from patients' files at discharge and follow-up clinic visits. The primary outcome of interest was death. Secondary outcomes of interest included discharge Glasgow Coma Scale (GCS) score, ICU admission, wound infection, and CSDH recurrence. RESULTS Two hundred five patients, the majority of whom were male (147 [72.8%]), were enrolled in the study. The mean patient age was 60.2 years (SD 17.7). Most CSDHs occurred as a result of motor vehicle collisions (MVCs) and falls, 35.6% (73/205) and 24.9% (51/205), respectively. The sex ratio and mean age varied depending on the mechanism of injury. Headache was the most common presenting symptom (89.6%, 173/193), whereas seizures were uncommon (11.5%, 23/200). Presenting symptoms differed by age. A total of 202 patients underwent surgical intervention with burr holes and drainage, and 22.8% (46) were admitted to the ICU. Two patients suffered a recurrence, 5 developed a postoperative wound infection, and 18 died. Admission GCS score was a significant predictor of the discharge GCS score (p = 0.004), ICU admission (p < 0.001), and death (p < 0.001). CONCLUSIONS Trauma from an MVC is the commonest cause of CSDH among the young. For the elderly, falling is common, but the majority have CSDH with no known cause. Although the clinical presentation is broad, there are several pronounced differences based on age. Burr hole surgery plus drainage is a safe and reliable intervention. A low preoperative GCS score is a risk factor for ICU admission and death.

Abstract
Abstract
BACKGROUND: For intracranial metastases with planning target volume (PTV) overlap of the brainstem (BSmet), the radiosurgical dose-fractionation that optimizes the therapeutic window is unknown. MATERIALS/METHODS: A retrospective review of brain metastases (BM) with/without BSmets treated with single-fraction stereotactic radiosurgery (SRS) or hypofractionated (2–5 fractions) radiosurgery (HF-SRS) between 2012–2016 was performed. Brainstem biologically effective doses (BED) and single-fraction equivalents of brainstem V10/V12 were calculated using α/β=3. Characteristics were compared between patients with/without BSmet and between SRS/HF-SRS cohorts using Wilcoxon rank sum, chi-square, or Fisher’s exact tests. Radiographic progression (RP) was assessed in patients with post-treatment contrasted MRI and defined as BSmet enlargement regardless of etiology (progression, radionecrosis, indeterminate). Kaplan-Meier estimates were compared between cohorts using log-rank test. RESULTS: 634 SRS/HF-SRS courses were identified, of which 59 (9.3%) treated ≥1 BSmet in 55 patients. BSmets occurred more commonly in patients with >4 BM (31% vs 10%, p< 0.001) and intracranial recurrence (39% vs 20%, p=0.003). BSmets were treated in 1 (22/59; 37%), 2 (1/59; 2%), or 5 (36/59; 61%) fractions. Age, KPS, and primary tumor site were balanced between SRS/HF-SRS cohorts. The HF-SRS cohort had significantly larger BSmet PTV (median 1.39cc vs 0.39cc, p=0.021), marginal dose (median 25Gy vs 15Gy, p< 0.001), brainstem V10 (median 1.60cc vs 0.47cc, p< 0.001), brainstem V12 (median 0.78cc vs 0.06cc, p< 0.001), and mean brainstem BED (median 9.27Gy3 vs 6.55Gy3, p=0.019). The SRS cohort was more likely to have prior whole brain radiotherapy (50% vs 14%, p=0.005) and restart steroids post-treatment (78% vs 41%, p=0.019). RP occurred in 6/17 vs 2/25 patients in the SRS vs HF-SRS cohorts, respectively (p=0.045). HF-SRS trended to higher freedom from RP (93% vs 74% @12mo; p=0.072). There was no overall survival difference (p=0.36). CONCLUSIONS: HF-SRS was associated with decreased RP and decreased likelihood of restarting steroids despite treating larger BSmets.

Abstract
BACKGROUND Promoting patients' rights is essential for defining the standards of clinical services within a country. Given their responsibilities, nurses can be the primary target for research to investigate the issue of patients' rights within a healthcare system. As such, assessing the knowledge of nurses about patients' rights is an essential step toward improving the quality of healthcare in limited resource settings like Sudan. OBJECTIVES We aimed to assess the level of knowledge about patients' rights among the nursing staff at Friendship Teaching Hospital in Sudan. METHODS This hospital-based cross-sectional study was carried out at the Friendship Teaching Hospital in Sudan. We surveyed the totality of nurses (95) at the hospital using an amended survey. The data were analyzed in SPSS software using descriptive and inferential statistics. ETHICAL CONSIDERATION The study was approved by the Research Unit of Khartoum Ministry of Health and the Hospital administration. All respondents gave verbal consent prior to participating in the study. RESULTS Only 48.4% of the participants knew about the existence of the Sudanese Charter of patients' rights. Nonetheless, our analysis found that 65.8% of nurses had acceptable level of knowledge (scored more than 75% of the total knowledge score) of patients' rights, and none of the participant scored less than 50% of the total knowledge score. Finally, we found no statistical association between the knowledge score and demographic data, educational level, whether the participant knows about the existence of the Charter or not and a number of other factors. CONCLUSION Nurses' lack of knowledge about the existence of the Sudanese Charter of patients' rights adopted in 2009 rights confirms the need for further efforts by Ministry of Health to promote the document. Furthermore, further research is needed to investigate the disconnect between nurses' lack of knowledge about the existence of the charter and their awareness of the rights within the charter as well as the actual implementation of rights.

Abstract
BACKGROUND Traumatic brain injuries (TBI) are a significant cause of mortality and morbidity for children globally. Adherence to evidence-based treatment guidelines have been shown to improve TBI outcomes. To inform the creation of a pediatric TBI management guideline for a low and middle income country context, we assessed the quality of available clinical practice guidelines (CPGs) for the acute management pediatric TBI. METHODS Articles were identified and retrieved from MEDLINE, EMBASE, Cochrane Library, LILACS, Africa-Wide Information and Global Index Medicus. These articles were screened by four reviewers independently. Based on the eligibility criteria, with the exception of literature reviews, opinion papers and editor's letters, articles published from 1995 to November 11, 2016 which covered clinical recommendations, clinical practice or treatment guidelines for the acute management of pediatric TBI (within 24 hours) were included for review. A reference and citation analysis was performed. Seven independent reviewers from low, middle and high income clinical settings with knowledge of pediatric TBI management appraised the guidelines using the AGREE II instrument. Scores for the CPGs were aggregated by domain and overall assessment was determined. RESULTS We screened 2372 articles of which 17 were retained for data extraction and guideline appraisal. Except for one CPG from a middle income country, the majority (16/17) of the guidelines were developed in high income countries. Seven guidelines were developed specifically for the pediatric population, while the remaining CPGs addressed the acute management of TBI in both adult and pediatric populations. The New Zealand Guideline Group (NZGG, 2006) received the highest overall assessment score of 46/49 (93.88%) followed by the Scandinavian Neurotrauma Committee (SNC, 2016) with a score of 45/49 (91.84%) followed by the Scottish Intercollegiate Guideline Network (SIGN, 2009) and Brain Trauma Foundation (BTF 2012) both with scores of 44/49 (89.80%). CPGs from Cincinnati Children's Hospital (CCH 2006) and Sao Paulo Medical School Hospital/Brazilian Society of Neurosurgery (USP/BSN, 2001) received the lowest score of 27/49 (55.10%) subsequently followed by the Appropriateness Criteria (ACR, 2015) with 29/49 (59.18%). The domains for scope and purpose and clarity of presentation received the highest scores across the CPGs, while applicability and editorial independence domains had the lowest scores with a wider variability in score range for rigor of development and stakeholder involvement. CONCLUSIONS To our knowledge, this is the first systematic review and guideline appraisal for pediatric CPGs concerning the acute management of TBI. Targeted guideline creation specific to the pediatric population has the potential to improve the quality of acute TBI CPGs. Furthermore, it is crucial to address the applicability of a guideline to translate the CPG from a published manuscript into clinically relevant local practice tools and for resource limited practice settings.

The impact of alcohol among injury patients in Moshi, Tanzania: a nested case-crossover study. BMC Public Health 2018; 18:275. [PMID: 29466975 PMCID: PMC5822650 DOI: 10.1186/s12889-018-5144-z] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2016] [Accepted: 02/01/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Globally, alcohol is responsible for 3.3 million deaths annually and contributes to 5.9% of the overall global burden of disease. In Sub-Saharan Africa, alcohol is the leading avoidable risk factor accounting for a substantial portion of death and disability. This project aimed to determine the proportion of injuries related to alcohol and the increased risk of injury due to alcohol among injury patients seeking care at the emergency department (ED) of Kilimanjaro Christian Medical Centre (KCMC) in Moshi, Tanzania. METHODS A representative cross-sectional sample of adult patients presenting to the KCMC ED with acute injury were enrolled in this study with a nested case-crossover design. Patient demographics, injury characteristics, and severity as well as alcohol use behaviors were collected. Alcohol breathalyzers were administered to the enrolled patients. Data on activities and alcohol use were collected for the time period 6 h prior to injury and two control periods: 24-30 h prior to injury and 1 week prior to injury. RESULTS During 47 weeks of data collection, 24,070 patients were screened, of which 2164 suffered injuries, and 516 met the inclusion and exclusion criteria, consented to participate, and had complete data. Of the study participants, 76% were male, and 30% tested positive for alcohol on arrival to the ED. Alcohol use was associated with being male and being employed. Alcohol use was associated with an increased risk of injury (OR 5.71; 95% CI 3.84-8.50), and specifically road traffic injuries were associated with the highest odds of injury with alcohol use (OR 6.53, 95% CI 3.98-10.71). For all injuries and road traffic injuries specifically, we found an increase in the odds of injury with an incremental increase in the dose of alcohol. CONCLUSIONS At KCMC in Moshi, Tanzania, 3 of 10 injury patients tested positive for alcohol on presentation for care. Similarly, alcohol use conveys an increased risk for injury in this setting. Evidence-based prevention strategies for alcohol-related injuries need to be implemented to reduce alcohol misuse and alcohol-related injuries.

Abstract
BACKGROUND The unmet surgical need, specifically neurosurgical need, in Uganda is significant, yet only 2 public hospitals currently perform neurosurgery in the country. This study examines the epidemiology and outcomes of neurosurgical conditions presenting to 1 of 12 regional referral hospitals in Uganda, in an effort to understand the neurosurgical needs of this population. METHODS The study was conducted at Mbarara Regional Referral Hospital (MRRH), in southwestern Uganda. Demographics, clinical characteristics, and outcomes were retrospectively collected for all patients who presented to MRRH with a neurosurgical condition between January 2012 and September 2015. RESULTS During the study period, 1854 patients presented to MRRH with a neurosurgical condition. More than half of the patients were between 19 and 40 years old, and the majority were males (76.1%). The overall median length of stay was 5 days (interquartile range: 2.5-10). The majority of admissions were due to trauma (87%), with almost 60% due to road traffic incidents. The overall mortality rate was 12.8%. A multivariable Cox proportional hazards model revealed that age, closed head injury, and admission Glasgow Coma Scale have a strong positive correlation with mortality while getting a diagnostic image and neurosurgical procedure were negatively correlated with mortality. CONCLUSION Traumatic brain injury represented the majority of neurosurgical admissions at MRRH, disproportionately affecting young males. Age, closed head injury, admission Glasgow Coma Scale, getting a diagnostic image, and neurosurgical procedure were all independent predictors of mortality. Resource appropriate interventions throughout the health system are needed to meet the demand and improve outcomes.

Abstract
Background Road traffic injuries (RTIs) are a growing but neglected global health crisis, requiring effective prevention to promote sustainable safety. Low- and middle-income countries (LMICs) share a disproportionately high burden with 90% of the world’s road traffic deaths, and where RTIs are escalating due to rapid urbanization and motorization. Although several studies have assessed the effectiveness of a specific intervention, no systematic reviews have been conducted summarizing the effectiveness of RTI prevention initiatives specifically performed in LMIC settings; this study will help fill this gap. Methods In accordance with PRISMA guidelines we searched the electronic databases MEDLINE, EMBASE, Scopus, Web of Science, TRID, Lilacs, Scielo and Global Health. Articles were eligible if they considered RTI prevention in LMICs by evaluating a prevention-related intervention with outcome measures of crash, RTI, or death. In addition, a reference and citation analysis was conducted as well as a data quality assessment. A qualitative metasummary approach was used for data analysis and effect sizes were calculated to quantify the magnitude of emerging themes. Results Of the 8560 articles from the literature search, 18 articles from 11 LMICs fit the eligibility and inclusion criteria. Of these studies, four were from Sub-Saharan Africa, ten from Latin America and the Caribbean, one from the Middle East, and three from Asia. Half of the studies focused specifically on legislation, while the others focused on speed control measures, educational interventions, enforcement, road improvement, community programs, or a multifaceted intervention. Conclusion Legislation was the most common intervention evaluated with the best outcomes when combined with strong enforcement initiatives or as part of a multifaceted approach. Because speed control is crucial to crash and injury prevention, road improvement interventions in LMIC settings should carefully consider how the impact of improvements will affect speed and traffic flow. Further road traffic injury prevention interventions should be performed in LMICs with patient-centered outcomes in order to guide injury prevention in these complex settings.
