Peripheral nerve injuries pose a significant clinical challenge due to the complex biological processes involved in nerve repair and their limited regenerative capacity. Despite advances in surgical techniques, conventional treatments, such as nerve autografts, are faced with limitations like donor site morbidity and inconsistent functional outcomes. As such, there is a growing interest in new, novel, and innovative strategies to enhance nerve regeneration. Tissue engineering/regenerative medicine and its use of biomaterials is an emerging example of an innovative strategy. Within the realm of tissue engineering, functionalized hydrogels have gained considerable attention due to their ability to mimic the extracellular matrix, support cell growth and differentiation, and even deliver bioactive molecules that can promote nerve repair. These hydrogels can be engineered to incorporate growth factors, bioactive peptides, and stem cells, creating a conducive microenvironment for cellular growth and axonal regeneration. Recent advancements in materials as well as cell biology have led to the development of sophisticated hydrogel systems, that not only provide structural support, but also actively modulate inflammation, promote cell recruitment, and stimulate neurogenesis. This review explores the potential of functionalized hydrogels for peripheral nerve repair, highlighting their composition, biofunctionalization, and mechanisms of action. A comprehensive analysis of preclinical studies provides insights into the efficacy of these hydrogels in promoting axonal growth, neuronal survival, nerve regeneration, and, ultimately, functional recovery. Thus, this review aims to illuminate the promise of functionalized hydrogels as a transformative tool in the field of peripheral nerve regeneration, bridging the gap between biological complexity and clinical feasibility.

The microbiota–gut–brain axis has garnered increasing attention in recent years for its role in various health conditions, including neuroinflammatory disorders like complex regional pain syndrome (CRPS). CRPS is a debilitating condition characterized by chronic neuropathic pain, and its etiology and pathophysiology remain elusive. Emerging research suggests that alterations in the gut microbiota composition and function could play a significant role in CRPS development and progression. Our paper explores the implications of microbiota in CRPS and the potential therapeutic role of boron (B). Studies have demonstrated that individuals with CRPS often exhibit dysbiosis, with imbalances in beneficial and pathogenic gut bacteria. Dysbiosis can lead to increased gut permeability and systemic inflammation, contributing to the chronic pain experienced in CRPS. B, an essential trace element, has shown promise in modulating the gut microbiome positively and exerting anti-inflammatory effects. Recent preclinical and clinical studies suggest that B supplementation may alleviate neuropathic pain and improve CRPS symptoms by restoring microbiota balance and reducing inflammation. Our review highlights the complex interplay between microbiota, inflammation, and neuropathic pain in CRPS and underscores the potential of B as a novel therapeutic approach to target the microbiota–gut–brain axis, offering hope for improved management of this challenging condition.

Psychiatric disorders often coexist with internal medical conditions, posing significant challenges to diagnosis, treatment, and overall patient outcomes. This study examines the bidirectional relationship between these conditions, emphasizing their impact on morbidity, treatment adherence, and quality of life. Through a comprehensive review of the peer-reviewed literature, we explore the physiological, neuroinflammatory, and psychosocial mechanisms that underpin these interactions. Key psychiatric disorders, including depression, anxiety, cognitive impairments, and psychosis, are identified as critical contributors to diagnostic complexity and therapeutic hurdles. Our findings underscore the importance of integrated, multidisciplinary care models, advocating for early detection, routine mental health screening, and personalized treatment strategies. Challenges such as overlapping symptoms, diagnostic ambiguities, and potential drug interactions are critically analyzed, with practical, evidence-based recommendations proposed for clinical practice. Despite advancements, significant research gaps persist, particularly the lack of longitudinal studies and the limited application of precision medicine tailored to this population. Future directions focus on enhancing diagnostic tools, developing innovative therapeutic approaches, and integrating mental health services into routine care. This study highlights the critical need for holistic, patient-centered approaches to manage comorbid psychiatric and internal medical conditions, offering actionable insights to improve outcomes and bridge existing gaps in research and practice.

Spinal cord injuries (SCIs) present a major clinical challenge, often resulting in permanent loss of function and limited treatment options. Traditional approaches, including surgery, drugs, and rehabilitation, have had modest success in restoring neural connectivity due to the complex pathophysiology of SCI. In recent years, bioactive hydrogels have gained attention as a versatile platform for neural repair. Their ability to mimic the extracellular matrix, deliver therapeutic agents, and support cell survival makes them promising tools in regenerative medicine. This narrative review highlights the latest advances in hydrogel-based therapies for SCI, with a focus on innovations such as self-healing, conductive, and anti-inflammatory hydrogels. We also explore hybrid approaches that integrate nanomaterials, stem cells, and bioelectronics to address both primary and secondary injury mechanisms. While various hydrogel systems have been investigated, we place particular emphasis on gelatin-based hydrogels, especially gelatin methacryloyl (GelMA), due to their emerging clinical relevance. GelMA stands out for its bioactivity, tunable mechanics, and compatibility with 3D printing, making it a strong candidate for personalized therapies and scalable production. Unlike previous reviews that broadly summarize hydrogel use, this work specifically contextualizes gelatin-based platforms within the wider landscape of SCI repair, underscoring their translational potential. We also address current challenges, such as immune response, long-term integration, and clinical validation, and suggest future directions for bridging the gap from bench to bedside.

The research article highlights the significance of acute myocardial infarction (AMI) and its impact on depression and anxiety among patients’ post-primary percutaneous coronary interventions (PCI). The study aims to determine the frequency of depression and anxiety occurrence in patients with acute myocardial infarction after primary PCI. The objective of this study is to investigate the frequency of depression and anxiety in patients with acute myocardial infarction after primary PCI. The method used in the study involved the collection of data from 88 patients with acute myocardial infarction who underwent primary PCI treatment. The patients were tested before PCI and then at intervals of 1 month, 6 months, and 12 months post-PCI using the Hamilton Depression Scale (HAM-D17) and the Hamilton Anxiety Scale (HAM-A) to identify depression and anxiety symptoms, respectively. The study performed a comprehensive analysis of the collected data to determine the frequency of depression and anxiety occurrence in post-PCI patients. The study found evidence that primary PCI reduces depression and anxiety in patients who have experienced a myocardial infarction. However, mental health issues continue to be a significant psychological concern for patients post-PCI, impacting their lifestyle, self-care, and treatment adherence. The study suggests that healthcare providers should actively screen and manage psychiatric disorders in patients who have suffered from AMI as they are at an increased risk of mental disorders. In conclusion, the study indicates that depression and anxiety are common issues in acute myocardial infarction survivors, and interventions addressing these conditions should be a routine part of care. The study highlights the need for healthcare providers to be aware of the increased risk of mental disorders in individuals who have suffered from AMI. Understanding the impact of anxiety and depression on post-PCI patients is essential for the development of effective interventions that support patients’ recovery.

Gastric cancer is a significant health concern worldwide, and lymphadenectomy plays a crucial role in its treatment. However, there is ongoing debate regarding the optimal approach—D1 or D2 lymphadenectomy. This paper aims to synthesize the available evidence by conducting a comprehensive literature review and comparing the advantages and disadvantages of both techniques. The analysis includes studies, clinical trials, and systematic reviews that assess survival outcomes, morbidity, and quality of life. The selected studies revealed different outcomes associated with D1 and D2 lymphadenectomy, including lymph node harvest, disease control, recurrence rates, and overall survival. Postoperative complications also varied between the two techniques. These findings highlight the complex considerations involved in selecting the most suitable lymphadenectomy approach for individual patients. Therefore, the decision requires an individualized assessment that considers the potential benefits and risks of D1 and D2 techniques. A collaborative approach involving interdisciplinary teams is crucial for developing personalized treatment plans that optimize both oncological outcomes and postoperative quality of life.
