The insertion/deletion polymorphism of angiotensin-converting enzyme (ACE) gene phenomenon and its relationship with essential hypertension has not been explored within the Ghanaian population. This study aims to determine the relationship between the ACE I/D polymorphism and the risk of essential hypertension among patients seeking medical attention.

View Article and Find Full Text PDFPurpose: Approximately 80% of brain metastases originate from non-small cell lung cancer (NSCLC). Immune checkpoint inhibitors (ICI) and stereotactic radiosurgery (SRS) are frequently utilized in this setting. However, concerns remain regarding the risk of radiation necrosis (RN) when SRS and ICI are administered concurrently.
View Article and Find Full Text PDFBackground: Despite recent advances in the management of severe traumatic brain injury, the role of decompressive craniectomy remains unclear. The purpose of this study was to compare practice patterns and patient outcomes between 2 study periods over the past decade.
Methods: This is a retrospective cohort study using the American College of Surgeons Trauma Quality Improvement Project database.
Purpose: Stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICI) are highly effective treatments for brain metastases, particularly when these therapies are administered concurrently. However, there are limited data reporting the risk of radiation necrosis (RN) in this setting.
Methods And Materials: Patients with brain metastases from primary non-small cell lung cancer, renal cell carcinoma, or melanoma treated with SRS and ICI were considered.
Background: African swine fever (ASF) is one of the most important foreign animal diseases to the U.S. swine industry.
View Article and Find Full Text PDFBackground: Melanoma brain metastases are commonly treated with stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICIs). However, the toxicity of these 2 treatments is largely unknown when administered concurrently.
Objective: To evaluate the risk of radiation necrosis (RN) with concurrent and nonconcurrent SRS and ICIs.
Objective: Immune checkpoint inhibitors (ICIs) and stereotactic radiosurgery (SRS) are commonly utilized in the management of brain metastases. Treatment-related imaging changes (TRICs) are a frequently observed clinical manifestation and are commonly classified as imaging-defined radiation necrosis. However, these findings are not well characterized and may predict a response to SRS and ICIs.

However, so far there is no evidence that intranasal delivery of NEO100 indeed results in POH reaching intracranial malignancies in a patient.
Observations: After surgical removal of her recurrent GBM tumor, a patient received daily intranasal NEO100 therapy for more than 3 years before a second recurrence emerged.
Introduction: Neurosurgical patients often undergo interhospital transfer (IHT) for specialized care. While IHT is often associated with worse outcomes in emergent neurosurgical conditions, less is known about patient outcomes after IHT for urgent diagnoses such as brain tumors. We sought to evaluate patient outcomes after IHT for malignant brain tumor resection.

An increasing body of evidence implicates multiple systems in the pathogenesis of this condition, though a unifying causative etiology remains elusive. Increased knowledge of the aberrations involved has shed light on the iNPH phenotype and has helped to guide prognostication for treatment with cerebrospinal fluid diversion.
View Article and Find Full Text PDFBackground: African swine fever (ASF) is a highly contagious and devastating pig disease that has caused extensive global economic losses. Understanding ASF virus (ASFV) transmission dynamics within a herd is necessary in order to prepare for and respond to an outbreak in the United States. Although the transmission parameters for the highly virulent ASF strains have been estimated in several articles, there are relatively few studies focused on moderately virulent strains.
View Article and Find Full Text PDFBackground: Patients with renal cell carcinoma (RCC) brain metastases are frequently treated with immune checkpoint inhibitors (ICIs) and stereotactic radiosurgery (SRS). However, data reporting on the risk of developing radiation necrosis (RN) are limited.
Methods: RN rates were compared for concurrent therapy (ICI/SRS administration within 4 weeks of one another) and nonconcurrent therapy with the χ test.
Understanding the amount of virus shed at the flock level by birds infected with low pathogenicity avian influenza virus (LPAIV) over time can help inform the type and timing of activities performed in response to a confirmed LPAIV-positive premises. To this end, we developed a mathematical model which allows us to estimate viral shedding by 10,000 turkey toms raised in commercial turkey production in the United States, and infected by H7 LPAIV strains. We simulated the amount of virus shed orally and from the cloaca over time, as well as the amount of virus in manure.

We studied a series of patients who had undergone craniotomy for aSDH, exploring a possible relationship between the occurrence of a postoperative extra-axial collection (EAC) and the presence of a ventricular shunt.
Methods: We reviewed all craniotomies for convexity aSDH performed between July 2015 and June 2020.
Introduction: This systematic review analyzes contemporary literature on racial/ethnic, insurance, and socioeconomic disparities within cerebrovascular surgery in the United States to determine areas for improvement.
Methods: We conducted an electronic database search of literature published between January 1990 and July 2020 using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for studies analyzing a racial/ethnic, insurance, or socioeconomic disparity within adult cerebrovascular surgery.
Results: Of 2873 articles screened for eligibility by title and abstract, 970 underwent full-text independent review by 3 authors.
Background: Increasing light is being shed on how race, insurance, and socioeconomic status (SES) may be related to outcomes from disease in the United States. To better understand the impact of these health care disparities in pediatric neurosurgery, we performed a systematic review of the literature.
Methods: We conducted a systematic review using PRISMA guidelines and MeSH terms involving neurosurgical conditions and racial, ethnic, and SES disparities.
Background: The impact of race, socioeconomic status (SES), insurance status, and other social metrics on the outcomes of patients with intracranial tumors has been reported in several studies. However, these findings have not been comprehensively summarized.
Methods: We conducted a PRISMA systematic review of all published articles between 1990 and 2020 that analyzed intracranial tumor disparities, including race, SES, insurance status, and safety-net hospital status.
The 2015 highly pathogenic avian influenza (HPAI) H5N2 outbreak affected more than 200 Midwestern U.S. poultry premises.

Methods: We conducted a database search of literature published between January 1990 and July 2020 using PRISMA guidelines for all studies investigating a disparity in any aspect of adult spine surgery care analyzed based on race/ethnicity, insurance status/payer, or socioeconomic status (SES).
Results: Of 2679 articles identified through database searching, 775 were identified for full-text independent review by 3 authors, from which a final list of 60 studies were analyzed.
