The aim of this in vitro study was to evaluate the preventive effect of different materials on dental erosion lesions by speckle coherent light scattering analysis. Forty bovine teeth were divided in the following groups (n = 10): 1) DURA- Preventive Treatment with Fluoride Varnish (Duraphat, Colgate-Palmolive); 2) ELX- Preventive treatment with Elmex® Erosion Protection Toothpaste (GABA International AG, Therwil, Switzerland); 3) MP- Preventive treatment with MI Paste® (GC America); and 4) REG- Preventive Treatment with Regenerate Enamel Science™ (Unilever). For all groups, each sample was divided into 3 areas: non-treatment (control); preventive treatment + erosive challenge; non-treatment + erosive challenge. The erosive challenge was carried out using Sprite® Zero soft drink (pH 2.58). After the erosive challenge, the samples were evaluated by speckle coherent light scattering method in the eroded area compared to the sound area. The results showed that there was a statistically significant difference between eroded area with and without preventive treatment, however, there was no statistically significant difference among the different preventive materials tested.

Apixaban to Prevent Covert Infarcts After Cryptogenic Stroke in Patients With Atrial Cardiopathy: A Secondary Analysis of the ARCADIA Randomized Clinical Trial.
JAMA Neurol
January 2025
Department of Neurology, UAB Heersink School of Medicine, University of Alabama at Birmingham, Birmingham.
Importance: In the Atrial Cardiopathy and Antithrombotic Drugs in Prevention After Cryptogenic Stroke (ARCADIA) randomized clinical trial, anticoagulation did not prevent recurrent stroke among patients with a recent cryptogenic stroke and atrial cardiopathy. It is unknown whether anticoagulation prevents covert infarcts in this population.
Objective: To test the use of apixaban vs aspirin for prevention of nonlacunar covert infarcts after cryptogenic stroke in patients with atrial cardiopathy.

Importance: Patients undergoing unplanned abdominal surgical procedures are at increased risk of surgical site infection (SSI). It is not known if incisional negative pressure wound therapy (iNPWT) can reduce SSI rates in this setting.
Objective: To evaluate the effectiveness of iNPWT in reducing the rate of SSI in adults undergoing emergency laparotomy with primary skin closure.

Importance: Biomarkers would greatly assist decision-making in the diagnosis, prevention, and treatment of chronic pain.
Objective: To undertake analytical validation of a sensorimotor cortical biomarker signature for pain consisting of 2 measures: sensorimotor peak alpha frequency (PAF) and corticomotor excitability (CME).
Design, Setting, And Participants: This cohort study at a single center (Neuroscience Research Australia) recruited participants from November 2020 to October 2022 through notices placed online and at universities across Australia.
Comparative Efficacy of Nonsteroid Immunosuppressive Medications in Childhood Nephrotic Syndrome.
JAMA Pediatr
January 2025
Division of Nephrology, The Hospital for Sick Children, Toronto, Ontario, Canada.
Importance: Cyclophosphamide and calcineurin inhibitors are the most used nonsteroid immunosuppressive medications globally for children with various chronic inflammatory conditions. Their comparative effectiveness remains uncertain, leading to worldwide practice variation. Nephrotic syndrome is the most common kidney disease managed by pediatricians globally and suboptimal treatment is associated with high morbidity.

Background: Epilepsy, a neurological disorder characterized by recurrent seizures, presents considerable difficulties in treatment, particularly when dealing with drug-resistant cases. Dapsone, recognized for its anti-inflammatory properties, holds promise as a potential therapeutic option. However, its effectiveness in epilepsy requires further investigation.
