A Series of Awake Craniotomy Procedures Performed in Iran

“Awake craniotomy” is a technique used in neurosurgical procedures, commonly performed to remove a tumor or an epileptogenicfocus while the patient is awake. There has been an increasing trend towards performing this type of procedure because of its advantages;above all, the ability to map the eloquent cortex to reduce post-surgical neurological sequel. The aim of this article is tointroduce 8 cases of awake craniotomies, performed in Loghman-e-Hakim hospital in Tehran, Iran. Patients were selected accordingto our specific criteria. Oral clonidine (4 g/kg), dexamethason (8 mg/IV), midazolam (0.03 mg/kg/IV), and sufentanil (3 g/kg/IV)were used as premedication. Patients underwent cerebral state monitoring and other monitoring modalities during the procedure.A laryngeal mask was used during the asleep phase of the anesthesia. General anesthesia was induced using propofol and lidocaine.Local anesthesia was provided with bupivacaine in the incision and pin insertion sites. Anesthesia was maintained using propofoland remifentanil infusion. A total of 8 patients underwent the procedure. No significant complications, including hemodynamicinstability, depressed respiration, the need to put the patient to sleep before mapping or tumor resection, intraoperative seizures,aspiration, and brain edema were observed in any of our patients. In conclusion, we believe that a modified asleep-awake-awaketechnique instead of the asleep-awake-asleep technique may provide less complications and less need to manage the patients’ airway.“Awake craniotomy” is a technique used in neurosurgical procedures, commonly performed to remove a tumor or an epileptogenicfocus while the patient is awake.

Usefulness of pulmonary artery diameter in diagnosing pulmonary hypertension in patients admitted to tuberculosis intensive care unit

AbstractObjective/backgroundPulmonary hypertension (PH) can be a complication of patients with severe pulmonary tuberculosis (TB). We aimed to study the correlation between pulmonary artery (PA) diameter (PAD) as measured by computed tomography (CT) and mean PA pressure (mPAP) as measured by echocardiography. We also aimed to determine the accuracy of PAD in diagnosing PH in patients with pulmonary TB.MethodsWe retrospectively investigated the correlation between PAD measured using CT and mPAP measured using echocardiography in 132 patients with TB and PH, and 68 patients with TB but without PH, admitted to the TB intensive care unit at Masih Daneshvari Hospital in Tehran, Iran. We used logistic regression analysis to determine the relationships between PAD, PA diameter to ascending aorta (AA) ratio, and area of PA to area of AA ratio with mPAP. Using receiver operating characteristic analysis, we examined the utility of the PAD in predicting PH (mPAP ⩾25mmHg).ResultsPAD had a significant correlation with mPAP (p<0.005 and r=0.47). Also, PA:AA ratio and area of PA to area of AA ratio had significant correlation with mPAP (r=0.48 and r=0.47, respectively; p<0.001). The threshold of 29mm for PAD was determined using ROC. This index had a sensitivity of 0.55, specificity of 70.2 and area under curve of 0.66.ConclusionAlthough PAD and PA:AA ratio are useful in assessing of presence of PH, we conclude that these CT parameters are not sufficient for ruling in or ruling out PH in this group of patients

The Geriatric Emergency Care Applied Research (GEAR) network approach: A protocol to advance stakeholder consensus and research priorities in geriatrics and dementia care in the emergency department

INTRODUCTION: Increasingly, older adults are turning to emergency departments (EDs) to address healthcare needs. To achieve these research demands, infrastructure is needed to both generate evidence of intervention impact and advance the development of implementation science, pragmatic trials evaluation and dissemination of findings from studies addressing the emergency care needs of older adults. The Geriatric Emergency Care Applied Research Network (https://gearnetwork.org) has been created in response to these scientific needs-to build a transdisciplinary infrastructure to support the research that will optimise emergency care for older adults and persons living with dementia. METHODS AND ANALYSIS: In this paper, we describe our approach to developing the GEAR Network infrastructure, the scoping reviews to identify research and clinical gaps and its use of consensus-driven research priorities with a transdisciplinary taskforce of stakeholders that includes patients and care partners. We describe how priority topic areas are ascertained, the process of conducting scoping reviews with integrated academic librarians performing standardised searches and providing quality control on reviews, input and support from the taskforce and conducting a large-scale consensus workshop to prioritise future research topics. The GEAR Network approach provides a framework and systematic approach to develop a research agenda and support research in geriatric emergency care. ETHICS AND DISSEMINATION: This is a systematic review of previously conducted research; accordingly, it does not constitute human subjects research needing ethics review. These reviews will be prepared as manuscripts and submitted for publication to peer-reviewed journals, and the results will be presented at conferences.Open Science Framework registered DOI: 10.17605/OSF.IO/6QRYX, 10.17605/OSF.IO/AKVZ8, 10.17605/OSF.IO/EPVR5, 10.17605/OSF.IO/VXPRS

Detecting Cognitive Impairment and Dementia in the Emergency Department: A Scoping Review

OBJECTIVES: To identify research and practice gaps to establish future research priorities to advance the detection of cognitive impairment and dementia in the emergency department (ED). DESIGN: Literature review and consensus-based rankings by a transdisciplinary, stakeholder task force of experts, persons living with dementia, and care partners. SETTING AND PARTICIPANTS: Scoping reviews focused on adult ED patients. METHODS: Two systematic scoping reviews of 7 medical research databases focusing on best tools and approaches for detecting cognitive impairment and dementia in the ED in terms of (1) most accurate and (2) most pragmatic to implement. The results were screened, reviewed, and abstracted for relevant information and presented at the stakeholder consensus conference for discussion and ranked prioritization. RESULTS: We identified a total of 1464 publications and included 45 to review for accurate tools and approaches for detecting cognitive impairment and dementia. Twenty-seven different assessments and instruments have been studied in the ED setting to evaluate cognitive impairment and dementia, with many focusing on sensitivity and specificity of instruments to screen for cognitive impairment. For pragmatic tools, we identified a total of 2166 publications and included 66 in the review. Most extensively studied tools included the Ottawa 3DY and Six-Item Screener (SIS). The SIS was the shortest to administer (1 minute). Instruments with the highest negative predictive value were the SIS (vs MMSE) and the 4 A\u27s Test (vs expert diagnosis). The GEAR 2.0 Advancing Dementia Care Consensus conference ranked research priorities that included the need for more approaches to recognize more effectively and efficiently persons who may be at risk for cognitive impairment and dementia, while balancing the importance of equitable screening, purpose, and consequences of differentiating various forms of cognitive impairment. CONCLUSIONS AND IMPLICATIONS: The scoping review and consensus process identified gaps in clinical care that should be prioritized for research efforts to detect cognitive impairment and dementia in the ED setting. These gaps will be addressed as future GEAR 2.0 research funding priorities

Emergency Department Care Transitions for Patients With Cognitive Impairment: A Scoping Review

ObjectivesWe aimed to describe emergency department (ED) care transition interventions delivered to older adults with cognitive impairment, identify relevant patient-centered outcomes, and determine priority research areas for future investigation.DesignSystematic scoping review.Setting and participantsED patients with cognitive impairment and/or their care partners.MethodsInformed by the clinical questions, we conducted systematic electronic searches of medical research databases for relevant publications following published guidelines. The results were presented to a stakeholder group representing ED-based and non-ED-based clinicians, individuals living with cognitive impairment, care partners, and advocacy organizations. After discussion, they voted on potential research areas to prioritize for future investigations.ResultsFrom 3848 publications identified, 78 eligible studies underwent full text review, and 10 articles were abstracted. Common ED-to-community care transition interventions for older adults with cognitive impairment included interdisciplinary geriatric assessments, home visits from medical personnel, and telephone follow-ups. Intervention effects were mixed, with improvements observed in 30-day ED revisit rates but most largely ineffective at promoting connections to outpatient care or improving secondary outcomes such as physical function. Outcomes identified as important to adults with cognitive impairment and their care partners included care coordination between providers and inclusion of care partners in care management within the ED setting. The highest priority research area for future investigation identified by stakeholders was identifying strategies to tailor ED-to-community care transitions for adults living with cognitive impairment complicated by other vulnerabilities such as social isolation or economic disadvantage.Conclusions and implicationsThis scoping review identified key gaps in ED-to-community care transition interventions delivered to older adults with cognitive impairment. Combined with a stakeholder assessment and prioritization, it identified relevant patient-centered outcomes and clarifies priority areas for future investigation to improve ED care for individuals with impaired cognition, an area of critical need given the current population trends
