Micronutrients and nutraceuticals play crucial roles in wound healing and tissue regeneration, supporting various physiological processes. This review aims to synthesize and evaluate the functions of various micronutrients and nutraceuticals, emphasizing the synergistic interactions among different nutrients that facilitate wound healing processes. A thorough literature review was performed using electronic databases, including PubMed, Scopus, Web of Science, Embase, Google Scholar, and Cochrane Library, to identify molecular studies, animal models, randomized controlled trials, and observational human studies published up to January 2000. Two independent reviewers screened the articles, extracted data, and evaluated the Risk of Bias using the Risk of Bias 2 (RoB 2) tool for the 190 studies that met the inclusion criteria. Evidence suggests that bioactive compounds found in functional foods and dietary supplements can help prevent chronic conditions and promote wellness beyond basic nutrition. Vitamins A, C, and E, as well as minerals such as zinc, selenium, and iron, are essential for cell proliferation and the formation of new tissues. Additionally, nutraceuticals, including omega-3 fatty acids, glutamine, arginine, and polyphenols, exhibit anti-inflammatory and antioxidant properties, which promote healing and reduce the risk of infection. Probiotics and other bioactive compounds in nutraceuticals contribute to maintaining the balance of microbiota, reducing inflammation, and stimulating cell regeneration. Significant variability was noted in study design, sample size, intervention dosage, and outcome measures. This evidence underscores the necessity for further well-designed clinical trials to determine the optimal dosages and combinations for specific wound types across diverse patient populations. This systematic review was prospectively registered in PROSPERO (ID: 1072091).

Skin aging is a complex biological process influenced by intrinsic factorssuch as genetic predispositions and hormonal changes as well as extrinsic factors including ultraviolet radiation, environmental pollution, and lifestyle habits. This process culminates in a progressive decline in the structural and functional integrity of the skin. This review delves into the protective roles of carotenoids, highlighting their significant anti-oxidative, anti-inflammatory, and photoprotective properties. We included studies that investigated the effects of dietary or topical carotenoids on skin aging markers in human and animal models. Eligible studies were identified through searches of PubMed, Scopus, Web of Science, Embase, Google Scholar, and the Cochrane Library from January 2000 to March 2025. Risk of bias was assessed using the Cochrane RoB tool for randomized trials and animal studies. A total of 176 studies were included, and data were synthesized narratively due to heterogeneity in study designs and outcomes. The findings indicate that carotenoids mitigate oxidative stress-induced cellular damage by scavenging reactive oxygen species (ROS) and Reactive Nitrogen Species (RNS), attenuating chronic inflammation, and enhancing dermal matrix integrity via collagen biosynthesis and modulation of matrix metalloproteinases. Additionally, they support skin hydration and elasticity by indirectly regulating aquaporins and promoting hyaluronic acid synthesis. This review further explores emerging strategies that incorporate carotenoid supplementation in lifestyle medicine and preventive dermatology. By elucidating the cellular pathways through which carotenoids exert their effects and modulate mitochondrial function, this review highlights their translational potential in anti-aging skincare. Ongoing research is essential to comprehend the complex connections between carotenoids, skin physiology, and overall health. This understanding will ultimately facilitate the creation of personalized nutritional and dermocosmetic strategies.

Gut microbiota has increasingly been shown to exert effects beyond the gastrointestinal tract, some of which are mediated through its metabolites, such as trimethylamine N-oxide (TMAO)—a compound converted by gut bacteria from dietary choline found predominantly in animal products that is associated with cardiovascular disease (CVD). However, a significant gap persists in human clinical trials assessing its potential causal role. This narrative review aims to present the current understanding of the gut microbiome, TMAO, and their relationship with CVD, while proposing future directions that may support the use of TMAO as a biomarker and guide potential interventions to reduce its harmful impact. Both animal and human studies have demonstrated a link between TMAO and CVD, with animal studies also indicating a causal effect—showing increased cardiovascular risk following TMAO administration and reduced risk when TMAO is eliminated. While direct extrapolation from animal models to humans is limited due to biological differences, these findings offer a foundation for the development of well-designed clinical trials in human populations. Although direct approaches to target TMAO—such as trimethylamine (TMA) lyase inhibitors and antisense oligonucleotide (ASO) therapy—have shown promising results in animal studies, they have yet to be investigated in human trials, leaving indirect strategies such as dietary changes and probiotics as the only currently available options.

Background/Objectives: Sepsis is a severe medical condition characterized by a dysregulated host response to infection, with potentially fatal outcomes, requiring early diagnosis and rapid intervention. The limitations of traditional sepsis identification methods, as well as the complexity of clinical data generated in intensive care, have driven increased interest in applying artificial intelligence in this field. The aim of this narrative review article is to analyze how artificial intelligence is being used in the diagnosis and prognosis of sepsis, to present the most relevant current models and algorithms, and to discuss the challenges and opportunities related to integrating these technologies into clinical practice. Methods: We conducted a structured literature search for this narrative review, covering studies published between 2016 and 2024 in databases such as PubMed/Medline, Scopus, Web of Science, IEEE Xplore, and Google Scholar. The review covered models based on machine learning (ML), deep neural networks (DNNs), Recurrent Neural Networks (RNNs), and clinical alert systems implemented in hospitals. The clinical data sources used, algorithms applied, system architectures, and performance outcomes are presented. Results: Numerous artificial intelligence models demonstrated superior performance compared to conventional clinical scores (qSOFA, SIRS), achieving AUC values above 0.90 in predicting sepsis and mortality. Systems such as Targeted Real-Time Early Warning System (TREWS) and InSight have been clinically validated and have significantly reduced the time to treatment initiation. However, challenges remain, such as a lack of model transparency, algorithmic bias, difficulties integrating into clinical workflows, and the absence of external validation in multicenter settings. Conclusions: Artificial intelligence has the potential to transform sepsis management through early diagnosis, risk stratification, and personalized treatment. A responsible, multidisciplinary approach is necessary, including rigorous clinical validation, enhanced interpretability, and training of healthcare personnel to effectively integrate these technologies into everyday practice.

Iron deficiency (ID) is a common comorbidity in heart failure (HF), affecting nearly 50% of patients and worsening symptoms, exercise capacity, and prognosis. This review summarizes recent evidence from meta-analyses, clinical trials, and guidelines on the pathophysiology, diagnosis, and treatment of ID in HF. ID in HF results from chronic inflammation, intestinal congestion, and impaired iron metabolism. Diagnosis is based on serum ferritin and transferrin saturation (TSAT) levels. While oral iron therapy has limited efficacy, intravenous iron, particularly ferric carboxymaltose and ferric derisomaltose, improves symptoms and exercise tolerance and reduces hospitalizations. Timely diagnosis and treatment of ID in HF are essential. Intravenous iron is the preferred therapeutic approach, but further research is needed to optimize long-term management.

Antiretroviral therapy (ART) effectively suppresses HIV replication but fails to eradicate latent reservoirs, leading to viral rebound after interruption. Chimeric antigen receptor (CAR) T-cell therapy offers a potential strategy to achieve durable remission. A systematic PubMed search (July 2020–June 2025) identified 253 studies on CAR-T therapy in HIV; 74 met inclusion criteria and were qualitatively analyzed. Preclinical data showed that CAR-T cells can recognize and eliminate infected cells, reach viral reservoirs, and persist long term, particularly when derived from hematopoietic stem cells. Dual-target and combination approaches with checkpoint inhibitors or latency-reversing agents enhanced antiviral efficacy. Early clinical studies confirmed safety and modest reservoir reduction. CAR-T cell therapy represents a promising step toward a functional HIV cure. Further optimization of design, integration with gene-editing technologies, and standardized clinical evaluation are required to confirm durable efficacy and safety.
