Surgical outcomes of premeatal and retromeatal cerebellopontine angle meningioma in Vietnam: a single-center prospective cross-sectional study.

Unlabelled: Cerebellopontine angle (CPA) meningiomas are the second most common tumor of the CPA. Depending on the site of dural attachment, the relationship between the tumor and critical neurovascular structures of the CPA is variable. This study aims to evaluate the influence of CPA meningioma location in relation to the internal auditory canal (IAC) on clinical symptoms, radiological presentations, and surgical treatments and outcomes which has been rarely reported in Vietnam.

SIV clearance from neonatal macaques following transient CCR5 depletion.

Treatment of people with HIV (PWH) with antiretroviral therapy (ART) results in sustained suppression of viremia, but HIV persists indefinitely as integrated provirus in CD4-expressing cells. Intact persistent provirus, the "rebound competent viral reservoir" (RCVR), is the primary obstacle to achieving a cure. Most variants of HIV enter CD4 T cells by binding to the chemokine receptor, CCR5.

Novel hazards of waterpipe tobacco and the benefits of stop smoking in men, a prospective cohort study.

Waterpipe smoking is an emerging epidemic and a severe public health problem worldwide. Observational studies on the hazards of a specific new waterpipe tobacco product are timely needed. The objectives were to analyze how dangerous waterpipe tobacco smoking is on the causes of all mortality, including cancer, and how effective smoking cessation is for improving health.

Cytomegalovirus infection disrupts the influence of short-chain fatty acid producers on Treg/Th17 balance.

Background: Both the gut microbiota and chronic viral infections have profound effects on host immunity, but interactions between these influences have been only superficially explored. Cytomegalovirus (CMV), for example, infects approximately 80% of people globally and drives significant changes in immune cells. Similarly, certain gut-resident bacteria affect T-cell development in mice and nonhuman primates.

Long-term outcomes of rotating gamma knife for vestibular schwannoma: A 4-year prospective longitudinal study of 89 consecutive patients in Vietnam.

Background: Microsurgical total removal of vestibular schwannoma (VS) is the definitive treatment but has a high incidence of postoperative neurological deficits. Rotating Gamma Knife (RGK) is a preferred option for a small tumor. This study aims to evaluate long-term neurological outcomes of RGK for VS.

T Cell Immune Profiles of Blood and Tumor in Dogs Diagnosed With Malignant Melanoma.

Investigation of canine T cell immunophenotypes in canine melanomas as prognostic biomarkers for disease progression or predictive biomarkers for targeted immunotherapeutics remains in preliminary stages. We aimed to examine T cell phenotypes and function in peripheral blood mononuclear cells (PBMC) and baseline tumor samples by flow cytometry, and to compare patient ( = 11-20) T cell phenotypes with healthy controls dogs ( = 10-20). CD3, CD4, CD8, CD25, FoxP3, Ki67, granzyme B, and interferon-γ (IFN-γ) were used to classify T cell subsets in resting and mitogen stimulated PBMCs.

Late recurrence of primary cerebellar germinoma at unusual site after complete response to radiotherapy.

Background: The primary cerebellar germinoma is exceptional and difficult to diagnose preoperatively. Its recurrence at the middle cranial fossa after complete response to radiotherapy is unique and associated with a poor prognosis. This article aims to report the successful management of the late recurrence of primary cerebellar germinoma at an unusual site after 4 years of complete response to radiotherapy.

Case Presentation: A 65-year-old female presented with a frequent nosebleed for one month before admission.

Acute spontaneous subdural hematoma secondary to ruptured arteriovenous malformation: A rare entity.

Introduction: Acute spontaneous subdural hematoma (ASSDH) due to ruptured arteriovenous malformation (AVM) is exceptional. There were only four reported cases. In this paper, we present a successful multimodality treatment of the ASSDH secondary to ruptured AVM.

Cytomegalovirus mediates expansion of IL-15-responsive innate-memory cells with SIV killing function.

Interindividual immune variability is driven predominantly by environmental factors, including exposure to chronic infectious agents such as cytomegalovirus (CMV). We investigated the effects of rhesus CMV (RhCMV) on composition and function of the immune system in young macaques. Within months of infection, RhCMV was associated with impressive changes in antigen presenting cells, T cells, and NK cells-and marked expansion of innate-memory CD8+ T cells.

Transient Effect of Infant Formula Supplementation on the Intestinal Microbiota.

Breastfeeding is the gold standard for feeding infants because of its long-term benefits to health and development, but most infants in the United States are not exclusively breastfed in the first six months. We enrolled 24 infants who were either exclusively breastfed or supplemented with formula by the age of one month. We collected diet information, stool samples for evaluation of microbiotas by 16S rRNA sequencing, and blood samples for assessment of immune development by flow cytometry from birth to 6 months of age.

Arachnoid cyst with spontaneous intracystic hemorrhage and associated chronic subdural hematoma: A case report.

Introduction And Importance: Spontaneous hemorrhage of the arachnoid cyst was rare, especially associated with chronic subdural hematoma (CSDH). In this paper, we reported successful surgical management of arachnoid cyst with spontaneous hemorrhage and associated subdural hematoma.

Case Presentation: A 33-year-old female with no medical history was presented with a headache for one month prior to admission.

RhCMV serostatus and vaccine adjuvant impact immunogenicity of RhCMV/SIV vaccines.

Rhesus cytomegalovirus (RhCMV) strain 68-1-vectored simian immunodeficiency virus (RhCMV/SIV) vaccines are associated with complete clearance of pathogenic SIV challenge virus, non-canonical major histocompatibility complex restriction, and absent antibody responses in recipients previously infected with wild-type RhCMV. This report presents the first investigation of RhCMV/SIV vaccines in RhCMV-seronegative macaques lacking anti-vector immunity. Fifty percent of rhesus macaques (RM) vaccinated with a combined RhCMV-Gag, -Env, and -Retanef (RTN) vaccine controlled pathogenic SIV challenge despite high peak viremia.

STA-MCA bypass following sphenoid wing meningioma resection: A case report.

Introduction: Sphenoid meningioma engulfed cerebral arteries has always been a challenge. To achieve a gross total resection, vessel sacrifice may be unavoidable.

Presentation Of Case: A 22-year-old man with a history of head trauma a week ago complained of a headache for one week.

Conventional digital subtractional vs non-invasive MR angiography in the assessment of brain arteriovenous malformation.

Objectives: Digital subtractional angiography (DSA) is the standard method for diagnosis, assessment and management of arteriovenous malformation in the brain. Conventional DSA (cDSA) is an invasive imaging modality that is often indicated before interventional treatments (embolization, open surgery, gamma knife). Here, we aimed to compare this technique with a non-invasive MR angiography (MRI DSA) for brain arteriovenous malformation (bAVM).

Changes in Circulating B Cell Subsets Associated with Aging and Acute SIV Infection in Rhesus Macaques.

Aging and certain viral infections can negatively impact humoral responses in humans. To further develop the nonhuman primate (NHP) model for investigating B cell dynamics in human aging and infectious disease, a flow cytometric panel was developed to characterize circulating rhesus B cell subsets. Significant differences between human and macaque B cells included the proportions of cells within IgD+ and switched memory populations and a prominent CD21-CD27+ unswitched memory population detected only in macaques.

Utilizing a TLR5-Adjuvanted Cytomegalovirus as a Lentiviral Vaccine in the Nonhuman Primate Model for AIDS.

Despite tremendous progress in our understanding of human immunodeficiency virus (HIV) natural history and advances in HIV treatment, there is neither an approved vaccine nor a cure for infection. Here, we describe the development and characterization of a novel replicating vaccine vector utilizing Cytomegalovirus (CMV) and a TLR5 adjuvant. After partial truncation of the central, immunodominant hypervariable domain, flagellin (fliC) from Salmonella was cloned downstream of a codon optimized gag gene from simian immunodeficiency virus (SIV) and transiently expressed in telomerized rhesus fibroblast (TeloRF) cells in culture.
