Sickle cell disease (SCD) is a hereditary hemoglobinopathy resulting from a β-globin chain mutation that causes abnormal hemoglobin (HbS) polymerization and leads to severe complications. Current treatment options primarily focus on symptom management, with limited curative potential. Recently, Casgevy, the first CRISPR/Cas9-based gene therapy for SCD, has received breakthrough FDA approval. Clinical trials have shown that Casgevy administered to patients aged older than or equal to 12 years enables precise modifications in hematopoietic stem cells, resulting in elevated fetal hemoglobin (HbF) levels and a significant reduction in vaso-occlusive events. Unlike conventional treatments, this therapy offers a curative approach and eliminates the need for recurrent transfusions and transplants, thereby improving the quality of life of patients with SCD. Casgevy has emerged as a beacon of hope for SCD patients and signifies a potential paradigm shift in SCD management due to its safety, curative potential, and transformative impact, positioning it as a groundbreaking intervention. Nevertheless, ethical considerations surrounding CRISPR technology and regulatory frameworks must be addressed to ensure responsible application and equitable access to this one-time gene editing therapy. As the authors celebrate this scientific advancement, sustained interdisciplinary collaboration and ethical scrutiny are essential to navigating the evolving landscape of CRISPR technology in medicine. This review aims to provide a detailed insight into the application of Casgevy, challenges associated with its application, future prospects of this therapy, and its comparison with existing treatment options for SCD.

Modern studies have linked gut microbiota to metabolic syndrome – a condition linked to obesity, characterized by insulin resistance, dyslipidemia, hyperglycemia, and hyperlipidemia. The gut microbiota, influenced by diet, plays a pivotal role in metabolic syndrome, affecting energy absorption, metabolism, and immune responses. Dysbiosis disrupts energy metabolism and immune responses contributing to metabolic endotoxemia, leading to insulin resistance and systemic inflammation. Key metabolites like short-chain fatty acids and bile acids, modulate insulin sensitivity and metabolic pathways. Therapeutic strategies involving probiotics and prebiotics show potential in managing diabetes and cardiovascular diseases by targeting lipid metabolism, inflammation, and atherosclerosis. However, challenges in therapy standardization and regulatory approval remain. Continued research on gut microbiota’s role in metabolic syndrome could lead to innovative, personalized treatment and prevention strategies based on individual metabolic profiles. The review aims to elucidate the underlying mechanisms that influence metabolic health and cardiovascular function. It seeks to synthesize current research findings, highlighting the role of microbial composition, diversity, and metabolic byproducts in the modulation of host metabolism and cardiovascular outcomes.
This review explores the bidirectional relationship between mental health disorders and cardiovascular disease (CVD), highlighting the potential of integrated healthcare models to improve outcomes. While CVD remains the leading cause of global mortality, traditionally linked to risk factors like hypertension and diabetes, emerging evidence shows that mental health conditions, especially depression and anxiety, significantly increase CVD risk through mechanisms such as chronic stress, inflammation, and neuroendocrine dysregulation. Activation of the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system exacerbates inflammation, elevates blood pressure, and contributes to cardiovascular risk factors. Moreover, the psychological burden of CVD often worsens mental health, creating a vicious cycle that complicates treatment adherence and patient management. Integrated care models offer a holistic approach to address these interconnected issues, potentially improving clinical outcomes, reducing healthcare costs, and enhancing patient adherence. This review also explores the role of telehealth and digital health interventions in overcoming accessibility barriers, particularly for underserved populations. Finally, policy recommendations emphasize the need for increased funding, professional training in interdisciplinary care, and targeted outreach to ensure equitable access to integrated care. By addressing both CVD and mental health challenges, these models could improve quality of life and reduce the global burden of these intertwined diseases.
