Background: The continuous changes in the medical education to prepare medical doctors for the future requires updates in medical curriculum. However, the perspectives of the medical students are not frequently considered during the revision of the medical curriculum. In parallel with the process of defining and adjusting the medical curriculum, a large survey was performed to inquire the perspectives of the medical students at the Faculty of Medicine of the University of Porto (FMUP), Portugal, about the role of Histology and of Embryology.Methods: Medical students at FMUP (Portugal) completed a structured and anonymous online questionnaire about the subjects Histology and Embryology. The questionnaire was prepared using questions of previous surveys performed in Europe, including another Portuguese medical school, and additional questions that were specifically prepared to this study. The questions referred to teaching methods, clinical relevance, use of virtual (digital) microscopes and association of Histology and Embryology with other subjects of the medical curriculum.Results: Four hundred and sixty-two students participated in the study. The students in clinical years were more likely to recognise the clinical relevance of Histology (p = 0.016) and Embryology (p < 0.001). Students agree that teaching of these subjects would benefit from a clinical orientation (89% for Histology; 90% for Embryology). Students highlighted that Histology is crucial to understand Biopathology and agree (75%) that an integration of Histology with Biopathology could be considered in the medical curriculum. Most students (55%) agree that slide microscopes are more useful than virtual microscopes.Conclusions: Our study contributes to the debate about the evolution of medical curriculum. Gathering the medical students’ perceptions using large surveys such as that performed in the present study may be useful to adapt the methods of teaching which may increase the motivation of the students. In the case of Histology and Embryology at the FMUP (Portugal) providing more clinically oriented teaching may be useful to motivate the students. Students of clinical years have strong clinical perspectives of Histology and Embryology and their enrolment in teaching of Histology and Embryology can also contribute to increase motivation of younger students. Consulting and involving medical students in the development of the medical curriculum can be positive and students should be more responsible and engaged in building their own education.

Temporomandibular disorders (TMDs) impact quality of life and present diagnostic and treatment challenges. Biomarkers may serve as an additional tool to support diagnosis and monitor disease progression, offering supplementary information for treatment strategies in specific and selected patients. This systematic review aimed to assess the role of biomarkers in diagnosing TMD and guiding personalized treatment. It also examined key biomarkers linked to chronic temporomandibular joint (TMJ) pain and how therapies affect biomarker levels and clinical outcomes. A comprehensive search was conducted in PubMed, Scopus, and Web of Science to identify observational and interventional studies assessing the role of biomarkers in synovial fluid/tissue, saliva, and blood. The research was registered in PROSPERO, adhered to PRISMA guidelines, and employed Cochrane Risk of Bias tools. To assess the effect, only studies examining biomarker levels were considered. A total of forty-six studies met the inclusion criteria: three randomized controlled trials were rated as having some concerns, as were most of the observational studies. Elevated levels of interleukins (1ß and 6), tumour necrosis factor alpha, and prostaglandin E2 in synovial fluid were correlated with temporomandibular joint (TMJ) inflammation. Increased matrix metalloproteinases (2, 7, and 9) indicated cartilage deterioration, while oxidative stress markers such as malondialdehyde were higher in TMD patients. Treatments including hyaluronic acid, platelet-rich plasma, and low-level laser therapy effectively reduced inflammatory biomarkers and improved symptoms. Biomarkers show potential to contribute to the understanding of pathophysiological mechanisms in TMD and may support future diagnostic and therapeutic strategies for selected patients. After high-quality studies confirm these findings, this approach will enable personalized medicine by tailoring treatments to individual patient profiles, ultimately leading to improved outcomes and quality of life.

Fibromyalgia is a prevalent chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, cognitive dysfunction, and sleep disturbances, with high impact in quality of life. Despite extensive research, the pathophysiological mechanisms of fibromyalgia remain partially understood, complicating the diagnosis and treatment. Some evidence underscores the central role of abnormal pain processing, particularly central sensitization and defective descending pain modulation pathways. This review synthesizes and discusses current findings on the neurobiological underpinnings of pain in fibromyalgia, with focus on descending inhibitory control mechanisms and on the role of biomarkers. We integrate data from neurochemical, neuroimaging, and clinical studies to explain how impaired descending modulation contributes to enhanced pain sensitivity and discuss the putative biomarkers associated with changes in descending modulation. A better understanding of descending pain modulation dysfunction in fibromyalgia and related biomarkers is crucial for improving clinical outcomes and developing novel and more effective treatments.

Mindfulness-Based Interventions (MBIs) are important tools to address mental health issues in children and adolescents. However, previous studies provided variable results that suggest that the effectiveness of those third-wave Cognitive Behavioral Therapies remains uncertain. Objectives: The main objective is to assess the impact of MBIs on anxiety, depression, and stress in children and adolescents. The secondary objective is to examine the modalities of MBIs used, the duration of interventions, and potential confounding factors, such as age. Methods: A comprehensive search of multiple databases was conducted to identify randomized clinical trials (RCTs) evaluating the effects of MBIs on mental health outcomes in children and adolescents. The research was registered in PROSPERO, adhered to PRISMA guidelines, employed the Cochrane Risk of Bias 2 tool, and calculated the effect sizes using mean differences. Results: Thirteen RCTs were included; ten were identified as having some concerns, while three were classified as having a low risk of bias. Mindfulness-Based Stress Reduction (MBSR) demonstrated a small positive effect on depression and anxiety, while non-specific MBIs showed a moderate positive effect both on depression and anxiety. Mindfulness-Based Cognitive Therapy (MBCT) was effective in reducing anxiety, depression (moderate positive effects on both), and stress symptoms. In one study, no significant improvements were seen on both anxiety and depression (for MBCT) and in another study on anxiety (for MBCT/MBSR). The meta-analysis did not identify a significant effect of mindfulness interventions on depression or anxiety. The high heterogeneity suggests varying outcomes, requiring further study of moderating factors. Conclusions: While some studies suggest benefits from MBIs, mainly MBCT’s ability to improve mental health outcomes in children and adolescents, their overall efficacy remains uncertain due to the high heterogeneity. The findings underscore the importance of considering the intervention type, duration, and moderating factors, such as age, when implementing MBIs.

Neuropathic pain is caused by a lesion or disease of the somatosensory system and is one of the most incapacitating pain types, representing a significant non-met medical need. Due to the increase in research in the field and since innovative therapeutic strategies are required, namely in intractable neuropathic pain, neurostimulation has been used. Within this approach, transcranial magnetic stimulation (TMS) that uses a transient magnetic field to produce electrical currents over the cortex emerges as a popular method in the literature. Since this is an area in expansion and due to the putative role of TMS, we performed a bibliometric analysis in Scopus with the primary objective of identifying the scientific production related to the use of TMS to manage neuropathic pain. The research had no restrictions, and the analysis focused on the characteristics of the literature retrieved, scientific collaboration and main research topics from inception to 6 July 2023. A total of 474 articles were collected. A biggest co-occurrence between the terms “neuropathic pain” and “transcranial magnetic stimulation” was obtained. The journal “Clinical Neurophysiology” leads the Top 5 most productive sources. The United States is the most productive country, with 50% of US documents being “review articles”, followed by France, with 56% of French documents being “original articles”. Lefaucheur, JP and Saitoh, Y are the two most influential authors. The most frequent type of document was “original article”. Most of the studies (34%) that identified the neuropathic pain type focused on traumatic neuropathic pain, although a large proportion (38%) did not report the neuropathic pain type. This study allows us to provide a general overview of the field of TMS application for neuropathic pain and is useful for establishing future directions of research in this field.

Giant cell tumor of bone (GCTB) is a distinctive, intermediate-grade primary bone neoplasm defined by a neoplastic mesenchymal stromal compartment and a prominent osteoclast-rich microenvironment. Although histologically benign, GCTB is clinically consequential due to its locally destructive behavior, propensity for recurrence, and rare capacity for metastasis and malignant transformation. Over the past decade, the identification of recurrent H3F3A p.G34 mutations has fundamentally reshaped the understanding of GCTB pathogenesis, establishing the stromal cell as the true neoplastic driver and positioning the tumor as a paradigmatic epigenetically driven osteolytic disease. This narrative review focus on biology, pathophysiology, and histopathology in the era of H3F3A. H3F3A-mutant stromal cells orchestrate pathological osteoclastogenesis through dysregulated RANKL signaling and chromatin reprogramming, giving rise to the characteristic cellular admixture of osteoclast-type giant cells, mononuclear histiocytic cells, and neoplastic stromal elements. The targeted inhibition of osteoclast activity with denosumab has transformed clinical management, inducing profound morphological changes and bone formation. However, its long-term impact on local control, recurrence patterns, and malignant progression remains unclear. Collectively, GCTB exemplifies a molecularly defined bone tumor in which advances in epigenetic biology and tumor–microenvironment interactions have directly influenced diagnostic practice and therapeutic strategy. Ongoing challenges include refining risk stratification, optimizing treatment sequencing, and clarifying the biological consequences of sustained osteoclast suppression.
