Global neurology

Sabato Santaniello, John T Gale, Sridevi V Sarma
Over the last 30 years, deep brain stimulation (DBS) has been used to treat chronic neurological diseases like dystonia, obsessive-compulsive disorders, essential tremor, Parkinson's disease, and more recently, dementias, depression, cognitive disorders, and epilepsy. Despite its wide use, DBS presents numerous challenges for both clinicians and engineers. One challenge is the design of novel, more efficient DBS therapies, which are hampered by the lack of complete understanding about the cellular mechanisms of therapeutic DBS...

Vaccines are considered one of the greatest advances in modern medicine. The global burden of numerous infectious diseases has been significantly reduced, and in some cases, effectively eradicated through the deployment of specific vaccines. However, efforts to develop effective vaccines against infectious pathogens such as influenza, HIV, dengue virus (DENV), chikungunya virus (CHIKV), Ebola virus, and Zika virus (ZIKV) have proven challenging. Zika virus is a mosquito-vectored flavivirus responsible for periodic outbreaks of disease in Africa, Southeast Asia, and the Pacific Islands dating back over 50 years...

INTRODUCTION: In recent years, delivery of cost-effective "essential neurosurgery" in resource-limited communities has been recognized as an indispensable part of health care and a global health priority. The purpose of this study was to review outcomes from operative management of spine trauma at a resource limited government hospital in Phnom Penh, Cambodia, and to provide an epidemiologic report to guide prevention programs. METHODS: A retrospective review of a prospective neurosurgical database was performed to identify risk factors for spine trauma and severe spinal cord injury (ASIA A or ASIA B) and to evaluate the cost-effectiveness of surgery for patients treated at Preah Kossamak Hospital for subaxial and thoracolumbar spine trauma from 2013 to 2016...

This work presents a novel approach for the rapid segmentation of clinically relevant subcortical brain structures in T1-weighted MRI by utilizing a shape-constrained deformable surface model. In contrast to other approaches for segmenting brain structures, its design allows for parallel segmentation of individual brain structures within a flexible and robust hierarchical framework such that accurate adaptation and volume computation can be achieved within a minute of processing time. Furthermore, adaptation is driven by local and not global contrast, potentially relaxing requirements with respect to preprocessing steps such as bias-field correction...

A neurological disorder is any disorder or abnormality in the nervous system. Among different neurological disorders, Alzheimer's disease (AD) is recognized as the sixth leading cause of death globally. Considerable research has been conducted to find pioneer treatments for this devastating disorder among which cell therapy has attracted remarkable attentions over the last decade. Up to now, targeted differentiation into specific desirable cell types has remained a major obstacle to clinical application of cell therapy...

: Neurological conditions associated with HIV remain major contributors to morbidity and mortality and are increasingly recognized in the aging population on long-standing combination antiretroviral therapy (cART). Importantly, growing evidence shows that the CNS may serve as a reservoir for viral replication, which has major implications for HIV eradication strategies. Though there has been major progress in the last decade in our understanding of the pathogenesis, burden, and impact of neurological conditions associated with HIV infection, significant scientific gaps remain...

To increase the efficiency and effectiveness of clinical research studies, cerebral palsy (CP) specific Common Data Elements (CDEs) were developed through a partnership between the National Institute of Neurological Disorders and Stroke (NINDS) and the American Academy of Cerebral Palsy and Developmental Medicine (AACPDM). International experts reviewed existing NINDS CDEs and tools used in studies of children and young people with CP. CDEs were compiled, subjected to internal review, and posted online for external public comment in September 2016...

Background & Aims:  Ischemic stroke has been ranked the second cause of death in patients worldwide.Inflammation which is activated during cerebral ischemia/reperfusion is an important mechanism leading to brain injury. This study aimed to investigate the effect of flurbiprofen axetil on cerebral I/R injury and the role of inflammation in this process. Methods:  Rats were subjected to sham operation or global cerebral I/R with or without flurbiprofen axetil (5 mg/kg or 10 mg/kg). Global cerebral ischemia was achieved by occlusion of bilateral common carotid arteries combined with hypotension for 20 min followed by reperfusion for 72 h...

BACKGROUND: Trauma is a global burden of disease and one of the main causes of death worldwide. Therefore, many countries around the world have implemented a wide range of different initiatives to minimize mortality rates after trauma. One of these initiatives is the bundling of treatment expertise in trauma centers and the establishment of trauma networks. Germany has a decentralized system of trauma care medical centers. Severely injured patients ought to receive adequate treatment in both level I and level II centers...

Out-of-hospital cardiac arrest (OHCA) is a leading cause of global mortality. Regional variations in reporting frameworks and survival mean the exact burden of OHCA to public health is unknown. Nevertheless, overall prognosis and neurological outcome are relatively poor following OHCA and have remained almost static for the past three decades. In this Series paper, we explore the aetiology of OHCA. Coronary artery disease remains the predominant cause, but there is a diverse range of other potential cardiac and non-cardiac causes to be aware of...

Zika virus (ZIKV) infection is an emergent worldwide public health problem. Historically, 84 countries have reported vector-borne ZIKV transmission, 61 of which report on-going transmission. It is a Flavivirus transmitted through arthropods belonging to the Aedes genus. Since 2015, ZIKV infections have increased dramatically; with 1.3 million people infected during 2015 in Brazil alone. This paper's objective is to highlight the conjectural epidemiological points of the virus' dissemination. The digital archives Pubmed, MEDLINE, EMBASE and Cochrane were searched for papers that assessed aspects of ZIKV transmission and epidemiology...

Neurological manifestations associated with HHV-7 have been described in primary infection in children, and very occasionally in immunocompromised adult patients. However, the role of HHV-7 reactivation as a cause of central nervous system (CNS) diseases in immunocompetent adults has not yet been defined. We retrospectively analyzed clinical and microbiological features of adults with neurological symptoms who underwent lumbar puncture and a multiplex polymerase chain reaction (PCR) for herpesviruses (HHV-1-8) and enteroviruses performed in cerebrospinal fluid (CSF), during a 4-year period...

Within the context of a globalising agenda for genetic research where 'global health' is increasingly seen as necessarily informed by and having to account for genomics, the focus on rare genetic diseases is becoming prominent. Drawing from ethnographic research carried out separately by both authors in Brazil, this paper examines how an emerging focus on two different arenas of rare genetic disease, cancer genetics and a class of degenerative neurological diseases known as Ataxias, is subject to and a product of the dynamics of inclusion and exclusion as this concerns participation in research and access to health care...

Importance: Aging is associated with excessive daytime sleepiness (EDS), which has been linked to cognitive decline in the elderly. However, whether EDS is associated with the pathologic processes of Alzheimer disease remains unclear. Objective: To investigate whether EDS at baseline is associated with a longitudinal increase in regional β-amyloid (Aβ) accumulation in a cohort of elderly individuals without dementia. Design, Setting, and Participants: This prospective analysis included participants enrolled in the Mayo Clinic Study of Aging, a longitudinal population-based study in Olmsted County, Minnesota...

Endocrine disruptors when introduced to waterways have many adverse health effects on wildlife and humans. These health effects vary from neurological, immune, carcinogenic and reproductive disorders. Currently, there are few wastewater treatment facilities that are purposefully treating endocrine disruptors as part of the normal wastewater treatment process. Current literature has shown that endocrine disruptors can be treated using conventional methods. These conventional methods are centered around the denitrification process, which is rarely adopted in Canada...
