Validation of computer vision technology for analyzing bradykinesia in outpatient clinic videos of people with Parkinson's disease.

Background: Current diagnosis and monitoring of Parkinson's disease (PD) is based on subjective clinical assessments. Objective measures of motor functioning could support clinical acumen. Computer vision (CV) technology is a promising contactless technique but requires further validation.

Smartphone automated motor and speech analysis for early detection of Alzheimer's disease and Parkinson's disease: Validation of TapTalk across 20 different devices.

Introduction: Smartphones are proving useful in assessing movement and speech function in Alzheimer's disease and other neurodegenerative conditions. Valid outcomes across different smartphones are needed before population-level tests are deployed. This study introduces the TapTalk protocol, a novel app designed to capture hand and speech function and validate it in smartphones against gold-standard measures.

Two-year 3D gait outcomes following in-situ pinning or modified Dunn procedure in children with slipped capital femoral epiphysis.

Background: Slipped Capital Femoral Epiphysis (SCFE) is femoral head slippage off the femoral neck through the physis occurring in children aged 8-16 years. Surgical intervention is required in all paediatric cases and there is no universal agreement on choice of surgical procedure.

Research Question: What are the two-year 3D gait outcomes in children with SCFE who have undergone in-situ pinning (PIN) or modified Dunn procedure (MDP) compared with normative reference values?

Methods: 17 children with SCFE who had undergone PIN (n=7, slip severity mild to moderate) or MDP (n=10, slip severity moderate to severe) surgical procedures prospectively underwent a 3D gait analysis post-surgery (2∙0 ± 0∙5 years).

Endodontic sequelae associated with repetitive impacts to the dentofacial region during boxing activities.

Aim: To explore self-reported dentofacial trauma and their potential endodontic sequelae in boxers using a questionnaire, followed by clinical and radiographic assessment to (1) compare the nature and number of self-reported dentofacial injuries with physical evidence of injury sequelae; and (2) investigate potential risk factors influencing dentofacial trauma and their endodontic sequelae.

Methodology: A focus group validated questionnaire was completed by 176 boxers recruited from 16 London boxing clubs; 61 boxers from this cohort then attended a London dental hospital, for a clinical and radiographic assessment. Data from the questionnaire and clinical assessments were then collated and analysed using Chi-squared or t-tests.

Clinical and Diagnostic Features of West Nile Virus Neuroinvasive Disease in New York City.

West Nile virus (WNV) neuroinvasive disease (WNND) occurs in approximately 1 percent of WNV-infected patients and typically presents as encephalitis, meningitis, or acute flaccid paralysis (AFP). WNND remains a difficult inpatient diagnosis, creating significant challenges for prognostication and therapy selection. We characterized the clinical and diagnostic features of WNND cases at two major academic medical centers in New York City in routine clinical practice.

Development of a smartphone screening test for preclinical Alzheimer's disease and validation across the dementia continuum.

Background: Dementia prevalence is predicted to triple to 152 million globally by 2050. Alzheimer's disease (AD) constitutes 70% of cases. There is an urgent need to identify individuals with preclinical AD, a 10-20-year period of progressive brain pathology without noticeable cognitive symptoms, for targeted risk reduction.

Modified cadaver technique to simulate contaminated airway scenarios to train medical providers in suction-assisted laryngoscopy and airway decontamination.

Simulation training plays a vital role in modern medical education, fostering safe skill development. Task-trainer manikin and cadaveric airway management training (CAMT) offer realistic airway management practice. Simulation allows learners the opportunity to manage high-risk, low-frequency scenarios, including difficult airways and massive airway contamination, common in emergent airway management.

Trends in Pediatric Anterior Cruciate Ligament Reconstruction in Australia: An Analysis of Australian Medicare Benefits Schedule Database From 2001 to 2020.

Background: Anterior cruciate ligament (ACL) injuries are common and increasingly prevalent in the pediatric population. However, there remain sparse epidemiological data on the surgical treatment of these injuries. The objective of this study is to assess the trends in the rate of pediatric ACL reconstruction in Australia over the past 2 decades.

Brief webcam test of hand movements predicts episodic memory, executive function, and working memory in a community sample of cognitively asymptomatic older adults.

Introduction: Low-cost simple tests for preclinical Alzheimer's disease are a research priority. We evaluated whether remote unsupervised webcam recordings of finger-tapping were associated with cognitive performance in older adults.

Methods: A total of 404 cognitively-asymptomatic participants (64.

Low Health Literacy, Lack of Knowledge, and Self-Control Hinder Healthy Lifestyles in Diverse Patients with Steatotic Liver Disease.

Introduction: In parallel with the obesity and diabetes epidemics, steatotic liver disease (SLD) has emerged as a major global public health concern. The mainstay of therapy is counseling on weight loss and increased exercise. However, such lifestyle modifications infrequently lead to success.

Black blood MRI sequences in the acute management of ruptured and unruptured intracranial aneurysms.

We present an illustrative case series in which high spatial resolution black blood (BB) MRI sequences were used as an adjunct in the acute management of intracranial aneurysms with diagnostic uncertainty regarding rupture status. Several acute management dilemmas are discussed including the surveillance of previously treated ruptured intracranial aneurysms, identifying culprit lesion(s) amongst multiple ruptured intracranial aneurysms, and risk stratifying incidental unruptured intracranial aneurysms. We present our experience which supports the evaluation of this vessel wall imaging technique in larger multi-centre observational studies.

Outcomes of Fluorescence-Guided vs White Light Resection of Glioblastoma in a Single Institution.

Background Glioblastoma (GBM) is the most common malignant primary brain tumour and confers a very poor prognosis. Maximal safe resection of tumour is the goal of neurosurgical intervention and may be more easily achieved through the use of surgical adjuncts such as fluorescence-guided surgery (FGS). 5-Aminolevulinic acid (5-ALA) accumulates in GBM tissue and fluoresce red, distinguishing tumour cells from the surrounding tissue and therefore making resection easier.

Estimating presymptomatic episodic memory impairment using simple hand movement tests: A cross-sectional study of a large sample of older adults.

Introduction: Finding low-cost methods to detect early-stage Alzheimer's disease (AD) is a research priority for neuroprotective drug development. Presymptomatic Alzheimer's is associated with gait impairment but hand motor tests, which are more accessible, have hardly been investigated. This study evaluated how home-based Tasmanian (TAS) Test keyboard tapping tests predict episodic memory performance.

Lived Experience-Led Research Agenda to Address Early Death in People With a Diagnosis of a Serious Mental Illness: A Consensus Statement.

Importance: People with serious mental illness (SMI), defined as a diagnosis of schizophrenia spectrum disorder, bipolar disorder, or disabling major depressive disorder) die approximately 10 to 25 years earlier than the general population.

Objective: To develop the first-ever lived experience-led research agenda to address early mortality in people with SMI.

Evidence Review: A virtual 2-day roundtable comprising 40 individuals convened on May 24 and May 26, 2022, and used a virtual Delphi method to arrive at expert group consensus.

If at first you don't succeed, should you try again? The efficacy of repeated closed reductions of distal radius fractures.

Introduction: A repeated closed reduction ("re-reduction") of a displaced distal radius fracture is a common procedure performed to obtain satisfactory alignment and avoid surgery when the initial reduction is deemed unsatisfactory. However, the efficacy of re-reduction is unclear. Compared to a single closed reduction, does a re-reduction of a displaced distal radius fracture: (1) improve radiographic alignment at the time of fracture union and, (2) decrease the rate of operative intervention?

Materials And Methods: Retrospective cohort analysis of 99 adults aged 20-99 years with extra-articular or minimally displaced intra-articular, dorsally angulated, displaced distal radius fracture with or without an associated ulnar styloid fracture who underwent a re-reduction, compared against 99 adults matched for age and sex who were managed with a single reduction.

Unruptured untreated intracranial aneurysms: a retrospective analysis of outcomes of 445 aneurysms managed conservatively.

Background: Factors predicting the growth or rupture of unruptured intracranial aneurysms (UIAs) remain under debate. Increased availability of neuro-imaging has led to increasing incidental findings, therefore understanding the natural history is vital to make appropriate management and follow-up decisions. We analysed a large dataset of UIAs to better identify patients at increased risk, therefore requiring enhanced monitoring and/or prophylactic intervention.

Risk of Aneurysm Rupture (ROAR) study: protocol for a long-term, longitudinal, UK multicentre study of unruptured intracranial aneurysms.

Introduction: Unruptured intracranial aneurysms (UIA) are common in the adult population, but only a relatively small proportion will rupture. It is therefore essential to have accurate estimates of rupture risk to target treatment towards those who stand to benefit and avoid exposing patients to the risks of unnecessary treatment. The best available UIA natural history data are the PHASES study.

A latent class analysis of health behavior changes after cancer diagnosis among Hispanic/Latino cancer survivors.

Purpose: We aimed to identify subgroups of Hispanic/Latino (H/L) cancer survivors with distinct health behavior patterns and their associated sociodemographic, medical, and psychosocial characteristics.

Methods: Baseline data were used from a randomized clinical trial evaluating the efficacy of an enhanced patient navigation intervention in H/L cancer survivors. Participants (n = 278) completed the Lifestyle Behavior Scale and validated questionnaires on health-related quality of life (HRQOL), supportive care needs, distress, and satisfaction with cancer care.
