AI-Based Analysis of Ziehl-Neelsen-Stained Sputum Smears for as a Screening Method for Active Tuberculosis.

Tuberculosis is the primary cause of death due to infection in the world. Identification of in sputum is a diagnostic test, which can be used in screening programs-especially in countries with a high incidence of tuberculosis-to identify and treat those persons with the highest risk of disseminating the infection. We previously developed an algorithm which is able to automatically detect mycobacteria on tissue; in particular, our algorithm identified acid-fast bacilli on tissue with 100% specificity, 95.

Sensitivity of Cerebellar Reaching Ataxia to Kinematic and Dynamic Demands.

Individuals with cerebellar ataxia often face significant challenges in controlling reaching, especially when multi-joint movements are involved. This study investigated the effects of kinematic and dynamic demands on reaching movements by individuals with cerebellar ataxia and controls using a virtual reality task. Participants reached target locations designed to elicit a range of coordination strategies between shoulder and elbow joint movements.

Safety and immunogenicity of the Ad26/protein preF RSV vaccine in adults aged 18 to 59 years with and without at-risk comorbidities for severe respiratory syncytial virus disease: A phase 3, randomized, controlled, immunobridging trial.

Background: Respiratory syncytial virus (RSV) causes a significant disease burden in adults with chronic comorbidities. Rates of severe RSV disease and death are as high, or higher in younger adults with risk factors than in healthy older adults in whom RSV vaccination is recommended. We conducted an immunobridging study using the Ad26/protein RSV preF vaccine, which previously demonstrated efficacy in adults aged ≥65 years to support extrapolation of efficacy demonstrated in an older population to younger adult populations at high risk of severe RSV disease.

Serum and mucosal antibody-mediated protection and identification of asymptomatic respiratory syncytial virus infection in community-dwelling older adults in Europe.

Introduction: Respiratory syncytial virus (RSV) causes acute respiratory tract infection (ARTI) and reinfects adults throughout life, posing a risk for hospitalization in older adults (>60 years) with frailty and comorbidities.

Methods: To investigate serum and mucosal antibodies for protection against RSV infections, baseline serum samples were compared for RSV-pre- and -post-fusion (F) binding, and RSV-A2 neutralizing IgG antibodies between symptomatic RSV-ARTI ( = 30), non-RSV (RSV negative) ARTI ( = 386), and no ARTI ( = 338). Mucosal RSV-pre-F IgA and IgG levels, as well as serum RSV-G IgG antibodies, were analyzed to determine their association with protection from symptomatic RSV-ARTI in a subset study.

Serial engagement of distinct motor learning mechanisms to alter walking after stroke.

This study asked if combining different motor learning mechanisms-adaptation and reinforcement-could produce immediate improvements in over ground walking after stroke. Fifteen adults with stroke engaged in three conditions: (1) reinforcement following adaptation, (2) reinforcement alone, and (3) adaptation alone. Adaptation involved split-belt treadmill walking to produce after-effects that reduce step asymmetry.

Immunogenicity and safety of different dose levels of Ad26.RSV.preF/RSV preF protein vaccine in adults aged 60 years and older: A randomized, double-blind, placebo-controlled, phase 2a study.

Background: Respiratory syncytial virus (RSV) can cause severe illness in older adults. A combination vaccine containing Ad26.RSV.

Addressing emotional distress to improve outcomes in adults with type 1 diabetes: Protocol for ACT1VATE randomized controlled trial.

Background: Diabetes distress (DD) is a prevalent concern among people with type 1 diabetes (T1D) and is linked to poor clinical outcomes. Instead of targeting the elimination of DD, we propose a novel approach that empowers individuals with strategies to manage their diabetes effectively in the context of DD: Acceptance and Commitment Therapy (ACT). The purpose of this in-progress trial is to compare an ACT group intervention (ACT1VATE) with usual care in improving HbA1c, DD, quality of life, and cost-effectiveness in adults with T1D.

Immunogenicity, safety and reactogenicity of Ad26.RSV.preF/RSV preF protein vaccine in adults aged 60 to 75 years: A comparison of phase 2b and phase 3 clinical trial material.

The Ad26.RSV.preF/RSV preF protein vaccine has previously demonstrated efficacyin protecting older adults against respiratory syncytial virus (RSV)-related lower respiratory tract disease in a phase 2b study.

Understanding mechanisms of generalization following locomotor adaptation.

Our nervous system has the remarkable ability to adapt our gait to accommodate changes in our body or surroundings. However, our adapted walking patterns often generalize only partially (or not at all) between different contexts. Here, we sought to understand how the nervous system generalizes adapted gait patterns from one context to another.

A Randomized, Double-Blind, Placebo-Controlled, Phase 1 Study to Evaluate the Safety, Reactogenicity, and Immunogenicity of Single Vaccination of Ad26.RSV.preF-Based Regimen in Japanese Adults Aged 60 Years and Older.

Background: Respiratory syncytial virus (RSV) is increasingly recognized as a significant cause of lower respiratory tract disease (LRTD) in older adults. The Ad26.RSV.

Long-term efficacy and immunogenicity of Ad26.RSV.preF-RSV preF protein vaccine (CYPRESS): a randomised, double-blind, placebo-controlled, phase 2b study.

Background: Ad26.RSV.preF-RSV preF protein showed 80·0% vaccine efficacy against respiratory syncytial virus (RSV) lower respiratory tract disease (LRTD) in older adults during one RSV season.

Immunogenicity and safety of Ad26.RSV.preF/RSV preF protein vaccine at predicted intermediate- and end-of-shelf-life as an evaluation of potency throughout shelf life.

This study assessed three Ad26.RSV.preF/RSV preF protein combinations, combining different Ad26.

Optimal reaching subject to computational and physical constraints reveals structure of the sensorimotor control system.

Optimal feedback control provides an abstract framework describing the architecture of the sensorimotor system without prescribing implementation details such as what coordinate system to use, how feedback is incorporated, or how to accommodate changing task complexity. We investigate how such details are determined by computational and physical constraints by creating a model of the upper limb sensorimotor system in which all connection weights between neurons, feedback, and muscles are unknown. By optimizing these parameters with respect to an objective function, we find that the model exhibits a preference for an intrinsic (joint angle) coordinate representation of inputs and feedback and learns to calculate a weighted feedforward and feedback error.

Outcomes of the Dulce Digital-COVID Aware (DD-CA) discharge texting platform for US/Mexico border Hispanic individuals with diabetes.

Background: Hispanic individuals have higher type 2 diabetes (T2D) prevalence, poorer outcomes, and are disproportionately affected by COVID-19. Culturally-tailored, diabetes educational text messaging has previously improved HbA1c in this population.

Methods: During the pandemic, hospitalized Hispanic adults with T2D (N = 172) were randomized to receive Dulce Digital-COVID Aware ("DD-CA") texting platform upon discharge plus diabetes transition service (DTS) or DTS alone.

A New Method of Artificial-Intelligence-Based Automatic Identification of Lymphovascular Invasion in Urothelial Carcinomas.

The presence of lymphovascular invasion (LVI) in urothelial carcinoma (UC) is a poor prognostic finding. This is difficult to identify on routine hematoxylin-eosin (H&E)-stained slides, but considering the costs and time required for examination, immunohistochemical stains for the endothelium are not the recommended diagnostic protocol. We developed an AI-based automated method for LVI identification on H&E-stained slides.

Biallelic variants in SNUPN cause a limb girdle muscular dystrophy with myofibrillar-like features.

Alterations in RNA-splicing are a molecular hallmark of several neurological diseases, including muscular dystrophies, where mutations in genes involved in RNA metabolism or characterized by alterations in RNA splicing have been described. Here, we present five patients from two unrelated families with a limb-girdle muscular dystrophy (LGMD) phenotype carrying a biallelic variant in SNUPN gene. Snurportin-1, the protein encoded by SNUPN, plays an important role in the nuclear transport of small nuclear ribonucleoproteins (snRNPs), essential components of the spliceosome.

Co-design of a personalised digital intervention to improve vegetable intake in adults living in Australian rural communities.

Background: Diets low in vegetables are a main contributor to the health burden experienced by Australians living in rural communities. Given the ubiquity of smartphones and access to the Internet, digital interventions may offer an accessible delivery model for a dietary intervention in rural communities. However, no digital interventions to address low vegetable intake have been co-designed with adults living in rural areas.

Concomitant Administration of Ad26.RSV.preF/RSV preF Protein Vaccine and High-Dose Influenza Vaccine in Adults 65 Years and Older: A Noninferiority Trial.

Background: Since influenza and respiratory syncytial virus (RSV) carry significant burden in older adults with overlapping seasonality, vaccines for both pathogens would ideally be coadministered in this population. Here we evaluate the immunogenicity and safety of concomitant administration of Ad26.RSV.

The Scale for Assessment and Rating of Ataxia Is Reliable and Valid in the Telehealth Setting for Patients With Cerebellar Ataxia.

Objective: Health care has increasingly expanded into a hybrid in-person/telehealth model. Patients with a variety of health conditions, including cerebellar ataxia, have received virtual health evaluations; however, it remains unknown whether some outcome measures that clinicians utilize in the telehealth setting are reliable and valid. The goal of this project is to evaluate the psychometric properties of the Scale for Assessment and Rating of Ataxia (SARA) for patients with cerebellar ataxia in the telehealth setting.

The Value of ER∝ in the Prognosis of GH- and PRL-Secreting PitNETs: Clinicopathological Correlations.

Pituitary neuroendocrine tumors (PitNETs) are divided into multiple histological subtypes, which determine their clinical and biological variable behavior. Despite their benign evolution, in some cases, prolactin (PRL) and growth hormone (GH)-secreting PitNETs may have aggressive behavior. In this study, we investigated the potential predictive role of ER∝, alongside the clinicopathological classification of PitNETs (tumor diameter, tumor type, and tumor grade).

The dual function of prokinesis in the feeding and locomotor systems of parrots.

Prokinesis, a mode of avian cranial kinesis involving motion between the neurocranium and upper beak, has long been investigated in biomechanical analyses of avian feeding and drinking. However, the modern avian beak is also used for non-feeding functions. Here, we investigate the dual function of prokinesis in the feeding and locomotor systems of the rosy-faced lovebird (Agapornis roseicollis).

T cells, more than antibodies, may prevent symptoms developing from respiratory syncytial virus infections in older adults.

Introduction: The immune mechanisms supporting partial protection from reinfection and disease by the respiratory syncytial virus (RSV) have not been fully characterized. In older adults, symptoms are typically mild but can be serious in patients with comorbidities when the infection extends to the lower respiratory tract.

Methods: This study formed part of the RESCEU older-adults prospective-cohort study in Northern Europe (2017-2019; NCT03621930) in which a thousand participants were followed over an RSV season.
