Objective: The objective of this guidance paper is to describe data transformation involving qualitization, including when and how to undertake this process, and to clarify how it aligns with data extraction in order to expand on the current guidance for JBI convergent integrated mixed methods systematic reviews (MMSRs).
Introduction: The convergent integrated approach to MMSRs involves combining extracted data from both quantitative studies (including the quantitative components of mixed methods studies) and qualitative studies (including the qualitative components of mixed methods studies). This process requires data transformation, which can occur either by converting qualitative data into quantitative data (ie, quantitizing) or converting quantitative data into qualitative data (ie, qualitizing).
Objective: For patients with aneurysmal subarachnoid hemorrhage (aSAH) in whom endovascular treatment is not the optimal treatment strategy, microsurgical clipping remains a viable option. We examined changes in morbidity and outcome over time in patients treated surgically and in relation to surgeon volume and experience.
Methods: All patients who underwent microsurgery for aSAH from 2007 to 2019 at our institution were included.
Importance: Trials often assess primary outcomes of traumatic brain injury at 6 months. Longer-term data are needed to assess outcomes for patients receiving surgical vs medical treatment for traumatic intracranial hypertension.
Objective: To evaluate 24-month outcomes for patients with traumatic intracranial hypertension treated with decompressive craniectomy or standard medical care.
Objectives: Mixed methods systematic reviews (MMSRs) combine quantitative and qualitative evidence within a single review. Since the revision of the JBI methodology for MMSRs in 2020, there has been an increasing number of reviews published that claim to follow this approach. A preliminary examination of these indicated that authors frequently deviated from the methodology.

CRP (C-reactive protein) has been reported to be associated with outcome, but it is unclear if this is independent of other predictors and applies to aSAH of all grades. Therefore, the role of CRP in aSAH outcome prediction models is unknown.

However, there is little evidence from randomized clinical trials that these therapies are safe and effective. The primary aim of this study was to apply game theory-based methods in explainable machine learning (ML) and propensity score matching to determine if rescue therapy was associated with better 3-month outcomes following post-SAH aVSP and DCI.

Introduction: Falls are a common cause of accidental injury, leading to significant safety issues in hospitals globally, and resulting in substantial human and economic costs. Previous research has focused on community settings with less emphasis on hospital settings.
Microglia, the tissue-resident macrophages of the central nervous system (CNS), play critical roles in immune defense, development and homeostasis. However, isolating microglia from humans in large numbers is challenging. Here, we profiled gene expression variation in primary human microglia isolated from 141 patients undergoing neurosurgery.

Introduction: Mixed methods systematic reviews provide a more complete basis for complex decision-making than that currently offered by single method reviews, thereby maximizing their usefulness to clinical and policy decision-makers. Although mixed methods systematic reviews are gaining traction, guidance regarding the methodology of combining quantitative and qualitative data is limited.
Objective: The objective of this review is to synthesize and integrate the best available evidence on the impact of canine-assisted interventions on the health and well-being of older people residing in long-term care.
Introduction: Canine-assisted interventions are commonly used as an adjunct therapy to enhance health and well-being, and are often implemented in long-term care facilities. The number of studies undertaken in this area has increased substantially over the previous five years; therefore, an update of two previous systematic reviews is warranted.

Objective: The objective of the proposed systematic review is to determine the barriers and enablers (or facilitators) to the implementation of pressure injury prevention among adults receiving care in the hospital setting.
Introduction: Hospital-acquired pressure injuries are preventable; however, they remain an ongoing safety and quality health care concern in many countries. There are various evidence-based preventative interventions for pressure injuries, but their implementation in clinical practice is limited.
Purpose: To synthesise the quantitative and qualitative evidence on the views and experiences of children and young people with epilepsy (CYPwE), their family members/caregivers and healthcare professionals on conversations between healthcare professionals and CYPwE/caregivers about the possibility of sudden unexplained death in epilepsy (SUDEP).
Methods: Mixed methods systematic review in accordance with Joanna Briggs Institute methodology, PRISMA guidelines and guided by an a-priori protocol.
Results: 656 potentially relevant studies were identified, 11 of which fulfilled the inclusion criteria for the review: 6 quantitative studies, 4 qualitative studies and 1 opinion/text article.
Background: Specific procedural complications in aneurysm surgery are broadly related to vascular territory compromise and brain/nerve retraction; vascular complications account for about half of this. Intraoperative indocyanine green video angiography (ICG-VA) provides real-time high spatial resolution imaging of the cerebrovascular architecture, allowing immediate quality assurance of aneurysm occlusion and vessel integrity. The aim of this study was to examine whether the routine use of ICG-VA reduced early procedural complications related to vascular compromise or injury during micro-neurosurgical clipping of ruptured cerebral aneurysms.

The current article provides an overview of an approach to incorporating a range of evidence, including qualitative research findings, which the authors piloted when developing a clinical guideline on epilepsies in children and young people. We describe methods used for incorporating literature types not usually included in Scottish Intercollegiate Guidelines Network guidelines, including critical appraisal, and establishing dependability and credibility of qualitative findings. We highlight limitations encountered and make suggestions for future work.

Methods: We prospectively enrolled adults with stable COPD who completed the University of Alabama at Birmingham Life Space Assessment (LSA) (range: 0-120, restricted Life-Space mobility: ≤60 and a marker of social isolation in older adults); six-minute walk test (6MWT), and the University of California at San Diego Shortness of Breath Questionnaire, COPD Assessment Test, and Hospital Anxiety and Depression Scale. The occurrence of severe exacerbations (emergency room visit or hospitalization) was recorded by review of the electronic record up to 1 year after enrollment.

The objective of this scoping review is to examine and map absolute clinical skill decay in the medical, nursing and allied health professions and to map the range of approaches used to address decay of clinical skills in these professions.Specifically, the review questions are: which clinical skills, performed by which professional groups, are reported to be most susceptible to absolute clinical skill decay, and what approaches have been reported for addressing absolute clinical skill decay in the medical, nursing and allied health professions?In addressing the review questions, the following sub-questions will also be addressed:It is anticipated that this scoping review will inform further systematic review/s on the topic of addressing clinical skill decay in the medical, nursing and allied health professions, as well as identify gaps in the research knowledge base that will inform further primary research.
View Article and Find Full Text PDFBackground: The management of aneurysmal subarachnoid hemorrhage (aSAH) has changed dramatically in the last few decades with the publication of a few major studies, including ISAT (International Subarachnoid Aneurysm Trial, the International Cooperative Study on the Timing of Aneurysm Surgery Study). The aim of this study is to analyze the outcome of patients with aSAH based on a contemporary series, identify the risk factors for poor outcome, and focus on patients with good-grade aSAH (to match the ISAT cohort).
Methods: Baseline demographic and outcome data (modified Rankin Scale) were available for the 803 patients recruited from the STASH (Simvastatin in Aneurysmal Subarachnoid Haemorrhage) trial for post hoc analysis, using a χ test or 2-sample t test.
