Background: The anterolateral thigh (ALT) flap is a reliable and versatile flap with the ideal characteristics for soft-tissue reconstruction. However, as it is known for its highly variable anatomy, it requires preoperative perforator localization to optimize flap design and dissection of the flap. Dynamic Infrared Thermography (DIRT) is a non-invasive and quick imaging method that provides real-time information.

- This study looked at why certain embedded performance validity indicators (EVIs) lead to higher false-positive rates (FPRs) in ADHD evaluations among adults, focusing on 15 EVIs from six cognitive tests.
- The research involved 517 adults with ADHD and found that while some EVIs had FPRs over 10% when used alone, combining them reduced the overall FPR to 8.1%.
- The study concluded that the choice of tests and the number of EVIs used are crucial for reducing FPRs in ADHD assessments, emphasizing the need for more refined approaches to test validity.
Calcium phosphate cement (CPC) has evolved as an appealing bone substitute material, especially since CPCs were combined with poly(lactic-co-glycolic acid) (PLGA) porogens to render the resulting CPC/PLGA composite degradable. In view of the multiple variables of CPC and PLGA used previously, the effect of CPC composition and PLGA porogen morphology (i.e.

- This study explored whether high cut-scores on the Barkley Adult ADHD Rating Scale-Fourth Edition (BAARS-IV) can indicate when adults might be overreporting ADHD symptoms during evaluations.
- Researchers analyzed data from 162 adults, dividing them into valid and invalid groups based on their symptom validity tests, and found that certain cut-scores effectively distinguished between these groups.
- The study suggests using specific cut-scores from the Current Total and Current Sluggish Cognitive Tempo scales together to better identify symptom overreporting, recommending that scores above these thresholds should lead to further examination of the patient's claims.
Article Synopsis
- - The study focuses on finding inhibitors that prevent the fusion of the herpes simplex virus type 1 (HSV-1) with host cell membranes, utilizing a virus-free cell culture system to model the fusion process.
- - Researchers identified aescin, a saponin mixture, as a specific inhibitor of HSV-1 membrane fusion, achieving significant reductions in viral entry and spread in cell assays.
- - Analytical methods revealed the main compounds present in aescin and their varying functionalities, with aescin IA showing promising inhibitory properties against HSV-1.
