Podocyte is one of the main components of glomerular filtration barrier in the kidney; the loss or dysfunction of podocyte could impair the functions of glomerular filtration barrier, leading to development of various renal diseases. Podocyte is a terminally differentiated cell, and thus does not possess any proliferative properties. Accordingly, its number and contribution to renal function are initially determined by its normal development. Information from the literature and results of our research indicate that genetic factors or prenatal adverse environment could cause developmental retardation of podocytes, thereby suggesting the potential fetal developmental origin(s) of kidney diseases, and involvement of epigenetic mechanisms in the regulation of key genes in podocyte development. In this review, we provide a brief overview on the podocyte normal development; discussion on the potential pathogenic mechanisms for developmental disorders of podocytes; as well as renal diseases associated with podocyte developmental retardation. We aim to provide some insights in articulating the strategies for diagnosis and treatments of renal diseases associated with podocyte developmental abnormalities.

Glucagon like peptide-1 (GLP-1) agonists and cardiometabolic protection: historical development and future challenges.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have revolutionized the treatment of cardiometabolic diseases, extending their therapeutic applications far beyond glycemic control in type 2 diabetes (T2D) and obesity. This editorial synthesizes key milestones, from the discovery of GLP-1 to recent clinical trials highlighting the pleiotropic effects of GLP-1RAs in addressing the interconnected spectrum of cardiometabolic conditions, with a focus on cardiovascular, renal, and hepatic benefits. In addition, as GLP-1RAs continue to reshape the management of cardiometabolic disease and global public health, we discuss future challenges to better elucidate their mechanisms of cardiometabolic protection and maximize their therapeutic potential.

Background: Lysinuric protein intolerance is a rare autosomal disorder caused by mutations in the Slc7a7 gene that lead to impaired transport of neutral and basic amino acids. The gold standard treatment for lysinuric protein intolerance involves a low-protein diet and citrulline supplementation. While this approach partially improves cationic amino acid plasma levels and alleviates some symptoms, long-term treatment is suggested to be detrimental and may lead to life-threatening complications characterized by a wide range of hematological and immunological abnormalities.

Background: Non-communicable diseases (NCDs) have become a major public health concern in Iraq, playing a significant role in the country's morbidity and mortality rates. To offer a thorough overview of the patterns and the overall impact of NCDs on public health, this study aims to map the trends in the incidence, prevalence, and mortality rates of NCDs in Iraq between 2003 and 2021.
Methods: Data from the Global Burden of Disease (GBD) Study 2021 were utilized.

Background: Oliguric acute kidney injury (AKI) is one of the critical conditions which needs emergent treatment due to the lack of the capacity of excreting toxins and fluids, and plasma membrane bleb formation is considered as one of the characteristic morphologic alterations in ischemic AKI in both animal models and human. We present here an autopsy case with clear electron microscopy images capturing a definitive instance of blebbing in ischemic AKI.
Case Presentation: A 66-year-old man was admitted for oliguric AKI with nephrotic syndrome (NS).

Therapeutic efficacy and safety of adeno-associated virus (AAV) liver gene therapy depend on capsid choice. To predict AAV capsid performance under near-clinical conditions, we established side-by-side comparison at single-cell resolution in human livers maintained by normothermic machine perfusion. AAV-LK03 transduced hepatocytes much more efficiently and specifically than AAV5, AAV8 and AAV6, which are most commonly used clinically, and AAV-NP59, which is better at transducing human hepatocytes engrafted in immune-deficient mice.
