An important impediment to the incorporation of artificial intelligence-based tools into healthcare is their association with so-called black box medicine, a concept arising due to their complexity and the difficulties in understanding how they reach a decision. This situation may compromise the clinician's trust in these tools, should any errors occur, and the inability to explain how decisions are reached may affect their relationship with patients. Explainable AI (XAI) aims to overcome this limitation by facilitating a better understanding of how AI models reach their conclusions for users, thereby enhancing trust in the decisions reached.

Background: Lung cancer (LC) patients are prone to suffer from malnutrition. Malnutrition negatively affects patients' response to therapy, increases the incidence of treatment-related side effects, and decreases survival. Early identification of LC patients who are malnourished or at risk of malnutrition can promote recovery and improve prognosis.

Penile cancer (PeCa) ranks as the 30th most prevalent cancer globally, predominantly affecting populations in developing countries. Phimosis and Human Papillomavirus (HPV) infection are recognized as the primary risk factors. Early-stage diagnosis typically warrants limited excision or non-invasive therapies.

Article Synopsis
  • Capsule endoscopy (CE) is a minimally invasive procedure used to examine the gastrointestinal tract, but it can be time-consuming and has limited diagnostic effectiveness in the upper GI tract.
  • Researchers developed an artificial intelligence (AI) model using convolutional neural networks (CNN) to automatically detect various types of pleomorphic lesions from a large dataset of CE images, evaluating its performance against expert classifications.
  • The AI model demonstrated high diagnostic accuracy across different areas of the GI tract, with the best results being 96.6% accuracy for gastric lesions and 97.6% for small bowel lesions, suggesting that AI tools could significantly enhance the effectiveness of capsule panendoscopy.

In plantations, coppice rotations often yield less than initial rotations. The TECHS project (Tolerance of Clones to Hydric, Thermal and Biotic Stresses) studied short rotation coppicing across a 3000 km gradient. The main objective of this work was to compare the survival, sprouting, and initial growth of clones managed and to examine factors that might influence the productivity of the coppice rotation: climate, genotypes, and stocking.

Introduction: Selective outcome reporting (SOR) is a bias that can occur in randomized controlled trials (RCTs), defined as the alteration or omission of primary outcome in the publication compared to the original protocol. Researchers may modify outcomes to highlight statistically significant results. This study aimed to assess the prevalence of SOR in RCTs related to dental caries in children and adolescents.

Background: Open Science Practices (OSPs) are essential when assessing research integrity and quality of Randomised Clinical Trials (RCTs). As dental caries represents a significant oral health burden, our objective was to identify and analyse the adoption of OSPs within RCTs focused on addressing this disease.

Methods: We searched PubMed to retrieve RCTs related to dental caries published from January 2000 to March 2022.

Micropropagation is an important tool for the propagation for recalcitrant species, like This is a first reported about a complete study of the , it includes the vegetative rescue protocol of mature trees, its micropropagation up to the implementation of a mini-garden and clonal micro-garden and evaluation of adventitious rooting of their propagules. The in vitro rejuvenation of genotypes (03, 05, 06, 13 and 15), over 21 successive subcultures, was evaluated by comparing minicutting and microcutting techniques and the efficiency of this biotechnological tool for cloning of the mature trees. The results provide evidence of the in vitro rejuvenation occurring in the mature trees during micropropagation, leading to increases in the multiplication ratios of the microstumps of three genotypes (03, 05 and 15).

Biology has become a highly mathematical discipline in which probabilistic models play a central role. As a result, research in the biological sciences is now dependent on computational tools capable of carrying out complex analyses. These tools must be validated before they can be used, but what is understood as validation varies widely among methodological contributions.

  • - The study investigates the differences in respiratory function and physical capacity between patients with chronic Chagas cardiomyopathy (CC) who have heart failure (HF) and those who do not.
  • - Using spirometry and a six-minute step test, the results showed that patients with HF had significantly lower lung function and functional capacity compared to those without HF.
  • - Conclusively, the research indicates that adults with CC and HF exhibit reduced lung function, suggesting a restrictive pulmonary pattern impacting their overall health.

The availability of manmade foodstuffs in the environment may significantly alter the diets, behavior and health of wild animals and the ecosystems ecology. One of the principal problems faced by urban populations of capuchin monkeys is their contact with household refuse, which may provoke a number of impacts on the health of these animals. The present study tested the use of feeding platforms as a strategy to reduce the consumption of unhealthy foodstuffs by these animals and analyzed the influence of this measure on the activity patterns and social interactions of the study groups.

: While human papillomavirus (HPV) is well known for its role in cervical cancer, it also affects vaginal cancers. Although colposcopy offers a comprehensive examination of the female genital tract, its diagnostic accuracy remains suboptimal. Integrating artificial intelligence (AI) could enhance the cost-effectiveness of colposcopy, but no AI models specifically differentiate low-grade (LSILs) and high-grade (HSILs) squamous intraepithelial lesions in the vagina.

The development of minimally invasive caries treatment has dramatically changed dentistry. Instead of traditional, often invasive methods that resulted in significant loss of healthy dental tissue, this approach focuses on preserving the vitality of the pulp and minimizing tissue loss by delaying and scaling back restorative treatments. This involves the use of modern methods, with selective caries removal with or without indirect (pulp) capping being the norm for treating extensive lesions.
