Purpose: To compare response patterns to video visual reinforcement audiometry (VVRA) and conventional visual reinforcement audiometry (CVRA) in infants 7-16 months of age.
Method: Fourteen normal-hearing infants aged 7-16 months (8 male, 6 female) participated. A repeated measures design was used. Each infant was tested with VVRA and CVRA over 2 different sessions. The total number of head turns prior to habituation, hit rate (response consistency), false alarm rate, and sensitivity for each reinforcement condition were evaluated.
Results: No significant differences were found between the 2 reinforcement methods for total number of head turns, hit rate, false alarm rate, or sensitivity. Overall, results showed no difference between the 2 reinforcer conditions in infants 7-16 months of age.
Conclusion: The results of the present study suggest that infants in the 7- to 16-month-old age range respond similarly to VVRA and CVRA as measured by response consistency and false alarm rate. VVRA is, therefore, a viable option for testing hearing in infants. However, prior to clinical implementation, the effectiveness of VVRA should be explored in infants with hearing loss.

Leishmania (Viannia) braziliensis causes cutaneous and mucocutaneous leishmaniasis. Macrophages are host cells for parasite replication and act as effector cells against the parasite. The two main macrophage phenotypes (M1 and M2) and their polarisation states have been implicated in Leishmania infection despite scarce data on L.

Purpose: We examined whether end-to-end deep-learning models could detect moderate (≥50%) or severe (≥70%) stenosis in the left anterior descending artery (LAD), right coronary artery (RCA) or left circumflex artery (LCX) in iodine contrast-enhanced ECG-gated coronary CT angiography (CCTA) scans.
Methods: From a database of 6293 CCTA scans, we used pre-existing curved multiplanar reformations (CMR) images of the LAD, RCA and LCX arteries to create end-to-end deep-learning models for the detection of moderate or severe stenoses. We preprocessed the images by exploiting domain knowledge and employed a transfer learning approach using EfficientNet, ResNet, DenseNet and Inception-ResNet, with a class-weighted strategy optimised through cross-validation.

: Multicomponent, non-pharmacological therapies are the preferred first-line treatments for fibromyalgia (FM), but little is known about them in primary care settings. Our study assessed the effectiveness of the FIBROCARE Program in improving the quality of life, functional impact, mood, and pain of people with FM. : We conducted a pragmatic, randomized controlled trial that was not blinded for both patients and the professionals delivering the treatments in the study groups.

In today's industrial landscape, optimizing energy consumption, reducing production times, and maintaining quality standards are critical challenges, particularly in energy-intensive processes like resistance spot welding (RSW). This study introduces an intelligent decision support system designed to optimize the RSW process for steel reinforcement bars. By creating robust machine learning models trained on limited datasets, the system generates interactive heat maps that provide real-time guidance to production engineers or intelligent systems, enabling dynamic adaptation to changing conditions and external factors such as fluctuating energy costs.

In addition to the traditional uses of plywood, such as furniture and construction, it is also widely used in areas that benefit from its special combination of strength and lightness, particularly as a construction material for the production of finishing elements of campervans and yachts. In light of the current need to reduce emissions of climate-damaging gases such as CO, the use of lightweight construction materials is very important. In recent years, hybrid structures made of carbon fibre-reinforced plastics (CFRPs) and metals have attracted much attention in many industries.
