Dynamic assessment of signal entropy for prognostication and secondary brain insult detection after traumatic brain injury.

Background: Entropy quantifies the level of disorder within a system. Low entropy reflects increased rigidity of homeostatic feedback systems possibly reflecting failure of protective physiological mechanisms like cerebral autoregulation. In traumatic brain injury (TBI), low entropy of heart rate and intracranial pressure (ICP) predict unfavorable outcome.

A Review of Neurosurgical randomized controlled trials in the Cochrane Database of Systematic Reviews: Key Findings and Implications for Future Research.

Objective: Evidence available to clinicians and patients to inform treatment decisions is ideally produced by randomized controlled trials (RCTs). The objective of this study was to assess the extent to which neurosurgical practice is supported by RCT-level evidence.

Methods: A search of the Cochrane Library was conducted to find reviews of the effectiveness of neurosurgical operative interventions.

Building resilient surgical systems that can withstand external shocks.

When surgical systems fail, there is the major collateral impact on patients, society and economies. While short-term impact on patient outcomes during periods of high system stress is easy to measure, the long-term repercussions of global crises are harder to quantify and require modelling studies with inherent uncertainty. When external stressors such as high-threat infectious disease, forced migration or climate-change-related events occur, there is a resulting surge in healthcare demand.

The application of medical ethics in the developing countries - A neurosurgical perspective.

Introduction: Neurosurgery is one of the rapidly evolving specialities of medical science, where the neurosurgeons have to provide evidence-based interventions in life threatening conditions maintaining the ethical standards.

Research Question: This narrative review sheds light on the current hindrances of the ethical aspects of neurosurgical practice in low and middle-income countries (LMICs) and provide some feasible solutions for future.

Material And Methods: A literature search was conducted using PubMed, Scopus and ISI web of knowledge focused on articles in English with the words "medical ethics" together with the words "neurosurgery", "ethical practice", "low and middle-income countries", "surgical innovation", "randomized clinical trials" and "outcome" alone or in combination.

Effect of Decompressive Craniectomy on Intracranial Pressure Waveforms and Vascular Reactivity: A Systematic Scoping Review.

Decompressive craniectomy (DC) primarily aims at decreasing intracranial pressure (ICP) by allowing for the brain tissue to expand. However, it is uncertain to what extent DC impacts the transmission of vasogenic slow waves and thus the validity and utility of the pressure reactivity index (PRx). The purpose of this systematically performed scoping review is to assess the current knowledge of the impact of DC on ICP waveforms and measures of vascular reactivity.

The Boston Declaration 2025: Plan and Pledges for Progress in Global Neurosurgery.

Global Neurosurgery has been described as the clinical and public health practice of neurosurgery with the primary purpose of ensuring timely, safe, and affordable neurosurgical care to all who need it. Global Neurosurgery activities in the form of mission trips, educational partnerships, and research collaborations have been in place for decades. Still, there have been no central organizing efforts to improve the harmonization of these endeavors until recently.

Collaborative Initiatives in Neurosurgery Research and Publications Between High-Income and Low/Middle-Income Countries: A Bibliometric Analysis.

Despite the globalization of health information, collaborations between high-income countries (HICs) and low/middle-income countries (LMICs), while present, could still increase. This study builds on previous research highlighting LMIC underrepresentation in neurosurgery literature. We conducted a comprehensive bibliometric analysis using the Scopus database to investigate collaborative neurosurgical research between HIC institutions and those in low-income country (LIC)/LMICs.

Achieving Equity Through Global Neurosurgery Research.

Since the release of the Lancet Commission on Global Surgery report in 2015, there has been an increase in the number of published papers on global neurosurgery, gaining widespread support from major neurosurgery journals. However, there remains no consensus on what may be considered part of global neurosurgery literature. Here, we propose that global neurosurgery research encompasses all scholarly work that measure, explore, or address inequity in the care of neurosurgical disease.

Global Neurosurgery: An Overview.

In the following article, we define the practice of global neurosurgery and review the major historical events defining this movement within the larger context of global surgery. The current state of the neurosurgical workforce, disease burden, and ongoing collaborative efforts are highlighted. Ethical practice leading the sustainability is discussed, as well as future targets for the global community as we look beyond the next decade of opportunities to affect the neurosurgical burden of disease.

Decompressive craniectomy in trauma: What you need to know.

Decompressive craniectomy (DC) is a surgical procedure in which a large section of the skull is removed, and the underlying dura mater is opened widely. After evacuating a traumatic acute subdural hematoma, a primary DC is typically performed if the brain is bulging or if brain swelling is expected over the next several days. However, a recent randomized trial found similar 12-month outcomes when primary DC was compared with craniotomy for acute subdural hematoma.

Research Question: We sought to provide an update on the current features of the software.

Differential signalling requirements for RIPK1-dependent pyroptosis in neutrophils and macrophages.

TLR4 and TNFR1 signalling promotes potent proinflammatory signal transduction events, thus, are often hijacked by pathogenic microorganisms. We recently reported that myeloid cells retaliate Yersinia blockade of TAK1/IKK signalling by triggering RIPK1-dependent caspase-8 activation that promotes downstream GSDMD and GSDME-mediated pyroptosis in macrophages and neutrophils respectively. However, the upstream signalling events for RIPK1 activation in these cells are not well defined.

Extended tests for evaluating post-traumatic brain injury deficits in resource-limited settings: methods and pilot study data.

Introduction: Traumatic brain injury (TBI) is one of the leading causes of all injury-related deaths and disabilities in the world, especially in low to middle-income countries (LMICs) which also suffer from lower levels of funding for all levels of the health care system for patients suffering from TBI. These patients do not generally get comprehensive diagnostic workup, monitoring, or treatment, and return to work too quickly, often with undiagnosed post-traumatic deficits which in turn can lead to subsequent incidents of physical harm.

Methods: Here, we share methods and results from our research project to establish innovative, simple, and scientifically based practices that dramatically leverage technology and validated testing strategies to identify post-TBI deficits quickly and accurately, to circumvent economic realities on the ground in LMICs.
