Long-Term Outcomes of Stereotactic Radiosurgery for Pineocytomas: An International Multicenter Study.

Background And Objectives: Pineocytomas are grade 1 tumors arising from the pineal parenchyma. Gross total resection can potentially cure these benign lesions but can be associated with morbidity. This study was designed to provide multi-institutional data to evaluate the results of stereotactic radiosurgery (SRS) for pineocytomas.

Vestibular Schwannoma Koos Grade II International Study of Active Surveillance Versus Stereotactic Radiosurgery: The VISAS-K2 Study.

Background And Objectives: This study assessed the efficacy and safety of stereotactic radiosurgery (SRS) in comparison with watchful waiting for managing Koos grade II vestibular schwannomas (VS).

Methods: A retrospective, multicentric analysis was conducted, focusing on patients with Koos grade II VS who either received SRS (SRS group) or were observed (observation group). To ensure comparability between groups, propensity score matching was used, including factors such as demographic characteristics, tumor dimensions, and hearing assessments.

Vestibular Schwannoma Koos Grade I International Study of Active Surveillance Versus Stereotactic Radiosurgery: The VISAS-K1 Study.

Background And Objective: This investigation evaluates the safety and efficacy of stereotactic radiosurgery (SRS) vs observation for Koos grade I vestibular schwannomas (VS).

Methods: In a multicenter study, we retrospectively analyzed data of patients with Koos grade I VS who underwent SRS (SRS group) or were observed (observation group). Propensity score matching was used to equilibrate demographics, tumor size, and audiometric data across groups.

The Association between Psychotropic Medication Use and Gait and Mobility Impairment in Community-Dwelling Older People. Data from The Irish Longitudinal Study on Ageing (TILDA).

Background: Little work to date has quantified the effect of psychotropic medications (antidepressants, benzodiazepines, 'Z' drugs, antipsychotics, anticholinergics) on mobility and gait in later life. The aim of this study is to examine the relationship between these medications and mobility/gait parameters in a large cohort of community-dwelling older people.

Methods: Participants were included if they were ≥60 years at TILDA Wave 1 and underwent gait and mobility assessment (Gaitrite system), with follow-up at Wave 3 (4 years).

Diagnosis and Treatment of Tethered Spinal Cord: A Systematic Review.

Context: Tethered cord syndrome is associated with motor and sensory deficits.

Objective: Our objective was to summarize evidence regarding the diagnosis, prophylactic surgery, symptomatic treatment, and repeat surgery of tethered spinal cord in a systematic review (CRD42023461296).

Data Sources And Study Selection: We searched 13 databases, reference-mined reviews, and contacted authors to identify diagnostic accuracy studies and treatment studies published until March 2024.

Minimum intraoperative testing battery for cochlear implantation: the international practice trend.

Purpose: In cochlear implantation (CI) surgery, there are a wide variety of intraoperative tests available. However, no clear guide exists on which tests must be performed as the minimum intraoperative testing battery. Toward this end, we studied the usage patterns, recommendations, and attitudes of practitioners toward intraoperative testing.

Everyday ageism experienced by community-dwelling older people with frailty.

Purpose: Ageism encapsulates stereotypes, prejudice and discrimination towards others or oneself based on age. While identified as the most frequent form of discrimination, relatively little work has captured the problem of day-to-day ageism faced by older people with frailty in community settings. The aim of this study therefore was to examine the prevalence of everyday ageism experienced by older people attending hospital-based ambulatory care services, and to clarify its association with measures of quality of life (QOL) and frailty.

is an important causative agent of bovine respiratory disease complex. Here, we report the complete genome sequence of a strain 91, which was isolated from a pneumonic lung tissue sample collected from a beef calf.

Characterization of Histophilus somni sialic acid uptake mutant (ΔnanP-ΔnanU) using a mouse septicemia and mortality model.

Histophilus somni is an important pathogen of the bovine respiratory disease complex, yet the mechanisms underlying its virulence remain poorly understood. It is known that H. somni can incorporate sialic acid into lipooligosaccharide (LOS), and sialylated H.

An injectable subunit vaccine containing Elongation Factor Tu and Heat Shock Protein 70 partially protects American bison from infection.

() is the etiologic agent of high mortality epizootics of chronic respiratory disease in American bison (). Despite the severity of the disease, no efficacious commercial vaccines have been licensed for the prevention of infection in bison. Elongation factor thermal unstable (EFTu) and Heat Shock Protein 70 (Hsp70, ) are highly conserved, constitutively expressed proteins that have previously been shown to provide protection against infection in cattle.

International Consensus Statements on Intraoperative Testing for Cochlear Implantation Surgery.

Objectives: A wide variety of intraoperative tests are available in cochlear implantation. However, no consensus exists on which tests constitute the minimum necessary battery. We assembled an international panel of clinical experts to develop, refine, and vote upon a set of core consensus statements.

Incidence of brain metastasis according to patient race and primary cancer origin: a systematic review.

Purpose: A systematic review was conducted to investigate differences in incidence and primary origin of synchronous brain metastasis (sBM) in varying racial groups with different primary cancers.

Methods: Adhering to PRISMA 2020 guidelines a search was conducted using PubMed and Ovid databases for publications from January 2000 to January 2023, with search terms including combinations of "brain metastasis," "race," "ethnicity," and "incidence." Three independent reviewers screened for inclusion criteria encompassing studies clearly reporting primary cancer sites, patient demographics including race, and synchronous BM (sBM) incidence.

Vestibular Schwannoma International Study of Active Surveillance Versus Stereotactic Radiosurgery: The VISAS Study.

Purpose: The present study assesses the safety and efficacy of stereotactic radiosurgery (SRS) versus observation for Koos grade 1 and 2 vestibular schwannoma (VS), benign tumors affecting hearing and neurological function.

Methods And Materials: This multicenter study analyzed data from Koos grade 1 and 2 VS patients managed with SRS (SRS group) or observation (observation group). Propensity score matching balanced patient demographics, tumor volume, and audiometry.

Comparative Clinical Effectiveness and Cost-Effectiveness of the Cochlear Osia System and Baha Attract System in Patients with Conductive or Mixed Hearing Loss or Single-Sided Deafness.

The aim of this study was to evaluate the comparative clinical effectiveness and cost-utility of the active transcutaneous Osia System versus the passive transcutaneous Baha Attract System for patients with conductive or mixed hearing loss or single-sided deafness in an Australian healthcare setting. In the absence of direct comparative evidence, an indirect treatment comparison (ITC) of the clinical effectiveness and utility gains was needed. The ITC was informed by three studies identified through a systematic literature review.

Neuromodulation of Eating Disorders: A Review of Underlying Neural Network Activity and Neuromodulatory Treatments.

Eating disorders are a group of psychiatric conditions that involve pathological relationships between patients and food. The most prolific of these disorders are anorexia nervosa, bulimia nervosa, and binge eating disorder. The current standard of care involves psychotherapy, pharmacotherapy, and the management of comorbid conditions, with nutritional rehabilitation reserved for severe cases of anorexia nervosa.

Transcriptomic profiles of Mannheimia haemolytica planktonic and biofilm associated cells.

Mannheimia haemolytica is the principal agent contributing to bovine respiratory disease and can form biofilms with increased resistance to antibiotic treatment and host immune defenses. To investigate the molecular mechanisms underlying M. haemolytica biofilm formation, transcriptomic analyses were performed with mRNAs sequenced from planktonic and biofilm cultures of pathogenic serotypes 1 (St 1; strain D153) and St 6 (strain D174), and St 2 (strain D35).

Long-term antipsychotic use, orthostatic hypotension and falls in older adults with Alzheimer's disease.

Purpose: Antipsychotic use in Alzheimer disease (AD) is associated with adverse events and mortality. Whilst postulated to cause/exacerbate orthostatic hypotension (OH), the exact relationship between antipsychotic use and OH has never been explored in AD-a group who are particularly vulnerable to neuro-cardiovascular instability and adverse effects of medication on orthostatic blood pressure (BP) behaviour.

Methods: We analysed longitudinal data from an 18-month trial of Nilvadipine in mild-moderate AD.

A parcellation-based connectomic model of hemispatial neglect.

Background And Purpose: Hemispatial neglect is characterized by a reduced awareness to stimuli on the contralateral side. Current literature suggesting that damage to the right parietal lobe and attention networks may cause hemispatial neglect is conflicting and can be improved by investigating a connectomic model of the "neglect system" and the anatomical specificity of regions involved in it.

Methods: A meta-analysis of voxel-based morphometry magnetic resonance imaging (MRI) studies of hemispatial neglect was used to identify regions associated with neglect.

Impact of Multiple Sclerosis Subtypes on Pain Management in Patients With Trigeminal Neuralgia After Stereotactic Radiosurgery: An International Multicenter Analysis.

Background And Objectives: Trigeminal neuralgia affects approximately 2% of patients with multiple sclerosis (MS) and often shows higher rates of pain recurrence after treatment. Previous studies on the effectiveness of stereotactic radiosurgery (SRS) for trigeminal neuralgia did not consider the different MS subtypes, including remitting relapsing (RRMS), primary progressive (PPMS), and secondary progressive (SPMS). Our objective was to investigate how MS subtypes are related to pain control (PC) rates after SRS.

Clinical Implications of Pituitary Adenomas Exhibiting Dual Transcription Factor Staining: A Case Series of 27 Patients.

Objective: According to the 2017 World Health Organization classification of neuro-endocrine tumors, pituitary adenomas (PAs) are classified according to immunoexpression of the pituitary-specific transcription factors (TFs). A small subset of PAs exhibit multiple TF staining on immunohistochemistry and we present a series of 27 pathologically-confirmed cases of dual TF staining PAs (dsTF-PAs), and report clinically relevant implications.

Methods: A retrospective chart review of a multi-institutional database of patients with PAs surgically resected between 2008-2021 was performed.
