Extended cognitive load induces fast neural responses leading to commission errors.

Extended performance of cognitively demanding tasks induces cognitive fatigue manifested with an overall deterioration of behavioral performance. In particular, long practice with tasks requiring impulse control is typically followed by a decrease in self-control efficiency, leading to performance instability. Here, we show that this is due to changes in activation modalities of key task-related areas occurring if these areas previously underwent intensive use.

The Effect of Plaque Detectors on the Color Stability of Two Types of Restorative Materials.

Objective: To investigate the color stability of a one-shade resin-based composite material (RC) and a glass-ionomer cement (GIC) after staining with plaque detectors (PDs) with different formulations and delivery forms.

Materials And Methods: Rectangular-shaped specimens (7 × 3 × 2 mm) were produced with RC (Venus Diamond One, Kulzer) and GIC (Fujy IX GP, GC) (n = 30). Further, the following PDs were used on the specimens: (1) tablets (T; Plaq-Search, TePe); (2) mouthwash (M; Plaque Agent, Miradent); and (3) light-curing liquid (L; Plaque test, Ivoclar).

Neuroethology of natural actions in freely moving monkeys.

The current understanding of primate natural action organization derives from laboratory experiments in restrained contexts (RCs) under the assumption that this knowledge generalizes to freely moving contexts (FMCs). In this work, we developed a neurobehavioral platform to enable wireless recording of the same premotor neurons in both RCs and FMCs. Neurons often encoded the same hand and mouth actions differently in RCs and FMCs.

Evaluation of vascular photobiomodulation for orofacial pain and tension type headache following COVID 19 in a pragmatic randomized clinical trial.

This pragmatic double-blind randomized clinical trial aims to assess the impact of vascular photobiomodulation on post-COVID-19 patients experiencing tension-type headache, orofacial pain, or both persisting for more than 3 months. Participants were divided into two groups: vascular photobiomodulation (VPBM) and simulated VPBM. Their conditions were evaluated using the Brief Pain Inventory (BPI), Visual Analogue Scale, and Headache Impact Test (HIT-6).

Design and Validation of a Tripping-Eliciting Platform Based on Compliant Random Obstacles.

The experimental study of the stumble phenomena is essential to develop novel technological solutions to limit harmful effects in at-risk populations. A versatile platform to deliver realistic and unanticipated tripping perturbations, controllable in their strength and timing, would be beneficial for this field of study. We built a modular tripping-eliciting system based on multiple compliant trip blocks that deliver unanticipated tripping perturbations.

CD3+CD4-CD8- Double-Negative Lymphocytes Are Increased in the Aqueous Humor of Patients with Retinitis Pigmentosa: Their Possible Role in Mediating Inflammation.

Recently, evidence has supported a significant role for immune and oxidative-mediated damage underlying the pathogenesis of different types of retinal diseases, including retinitis pigmentosa (RP). Our study aimed to evaluate the presence of immune cells and mediators in patients with RP using flow cytometric analysis of peripheral blood (PB) and aqueous humor (AH) samples. We recruited 12 patients with RP and nine controls undergoing cataract surgery.

Seasonal patterns of myositis-specific and myositis-associated autoantibodies in Italy: Seasonal patterns of myositis autoantibodies.

Objective: Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of systemic autoimmune disorders affecting skeletal muscles but also other organs. There are different forms of IIM, each with peculiar clinical manifestations and prognosis. Accordingly, several autoantibodies have been described in IIM, with different prevalence in the different forms of the disease.

Service Delivery Redesign for Noncommunicable Disease Management: Assessment of Needs and Solutions Through a Co-Creation Process in Argentina.

Introduction: In Argentina, the implementation of a national strategy to reduce the prevalence of noncommunicable diseases (NCDs) has been hampered by challenges at the provincial level. We aimed to design a new model of care for NCDs at the primary care level by conducting a multimodal system assessment and co-design of potential solutions in the province of Mendoza.

Methods: We carried out a mixed-methods study with 7 components: evaluation of patterns of care, patient focus groups, cross-sectional standardized population-based phone survey, an electronic cohort follow-up of patients with type 2 diabetes, in-depth interviews with stakeholders, a knowledge test for health care providers on chronic condition management, and a Delphi consensus to provide recommendations from stakeholders.

Dopaminergic therapy disrupts decision-making in impulsive-compulsive Parkinsonian patients.

Impulsive-compulsive behaviors (ICB) are common non-motor symptoms of Parkinson's disease (PD) often associated with dopaminergic drugs (DD) therapy. We investigated the acute effects of DD on decision-making in PD patients with ICB (ICB+) and without it (ICB-), and in healthy controls (HC). Participants performed a risk-based decision-making task twice, with PD patients tested before (DD OFF) and after (DD ON) DD intake.

Adaptive vs. Conventional Deep Brain Stimulation: One-Year Subthalamic Recordings and Clinical Monitoring in a Patient with Parkinson's Disease.

Conventional DBS (cDBS) for Parkinson's disease uses constant, predefined stimulation parameters, while the currently available adaptive DBS (aDBS) provides the possibility of adjusting current amplitude with respect to subthalamic activity in the beta band (13-30 Hz). This preliminary study on one patient aims to describe how these two stimulation modes affect basal ganglia dynamics and, thus, behavior in the long term. We collected clinical data (UPDRS-III and -IV) and subthalamic recordings of one patient with Parkinson's disease treated for one year with aDBS, alternated with short intervals of cDBS.

Dosimetry model for photobiomodulation based on anthropometric and hemodynamic variables in patients with orofacial pain post-Covid-19: Study protocol for randomized clinical trial.

Introduction: Orofacial pain and tension headache are symptoms that affect a large portion of the population, compromising productivity, social ability, and functional development. The treatment for reducing painful sensation should be chosen carefully, as pharmacological treatment may bring side effects and overload the organism of patients in pain. Low-level laser therapy has been used with local and systemic [vascular] applications for pain control.

Bypassing Sources of Care by Level and Coverage: Access to Essential Services in Peru and Uruguay in the Post-Pandemic Era.

Background And Aims: Healthcare provision to distinct social groups in Latin America contributes to inequities. Individuals make active choices by bypassing their coverage and intended healthcare source. After the pandemic, we sought to characterize bypassing behaviors and quantify their effects on access to essential services.

Issues in autoantibody tests used in the classification criteria for autoimmune rheumatic diseases: the laboratory autoimmunologist's perspective.

Classification criteria of autoimmune rheumatic diseases are an important means to define homogenous groups of patients that can be compared across studies for clinical trials and research purposes. The measurement of autoantibodies is a relevant aspect in the definition of classification criteria, with a significant weight in the scores necessary to classify patients with autoimmune rheumatic diseases. The impact of autoantibodies has gradually increased over the years, contributing to the evolution and improvement of the classification criteria.
