Summary: This study used secondary ion mass spectrometry imaging to investigate the lipid organization in the plasma membranes of hippocampal neurons. Distinct lipid organization and significant alterations in levels of membrane lipids, especially ceramides, phosphatidylserines, phosphatidic acids, and triacylglycerols, were observed under the treatments of tetrodotoxin (TTX) and bicuculline (BIC). Many types of membrane lipids are suggested to be affected by, and involved in, the regulation of neuronal function.

Summary: Healthy adipose tissue is crucial for human wellbeing, contributing to energy balance and internal organ insulation, and playing a role in synthesizing and secreting adipokines affecting glucose and lipid balance. Inflammation induced by obesity in adipose tissue is linked to insulin resistance, metabolic syndrome, type 2 diabetes, as well as cardiovascular diseases, while alterations in perirenal adipose tissue have implications for renal and cardiovascular function. This suggests potential avenues for future pharmacological therapies targeting adipose tissue immunometabolism in the treatment of chronic kidney disease and cardiovascular disorders.

Summary: The abnormal functioning of proteasome is associated with crucial pathological conditions, such as neurodegeneration. However, the complex underlying causes at the cellular level are still unclear, and there are conflicting reports on the neuroprotective and neurodegenerative effects of proteasomal inhibitors like lactacystin, which are used as models for neurodegenerative diseases. The conflicting results may be due to different doses of lactacystin. Hence, a dose-dependent study was conducted to investigate the effects of lactacystin on cell membrane lipid profile and exocytosis dynamics.

Summary: Chronic kidney disease (CKD) is associated with metabolic and nutritional abnormalities, including resistance to insulin-like growth factor-1 (IGF-1) and reduced muscle mass and strength. Low levels of IGF-1 and hand-grip muscle strength (HGS) are independent predictors of increased mortality in CKD patients. The association of IGF-1 with survival in CKD patients depends on nutritional status.

Summary: The pathophysiology of vascular disease is associated with accelerated biological aging and a combination of various risk factors. Chronic kidney disease (CKD) serves as a valuable model to study the structural, functional, and molecular aspects of arterial aging. The cardiorenal syndrome results from the detrimental interaction between the kidney and the cardiovascular system. Understanding the molecular mechanisms of uremic early vascular aging provides insights into inflammatory pathways and emerging risk factors, offering new prospects for pharmacological and nutritional interventions.

Summary: Kidney transplantation is the preferred treatment for chronic kidney disease patients, offering improved quality of life and reduced mortality compared to dialysis. However, cardiovascular disease remains a leading cause of death in this population. A study investigated the functional properties of blood vessels two years after kidney transplantation and found that vessel stiffness improved while endothelial function worsened. Additionally, higher levels of a particular compound, indoxyl sulphate, were associated with decreased endothelial function and increased P-selectin levels after transplantation. Further experiments revealed that indoxyl sulphate impaired endothelium-dependent relaxation, potentially contributing to cardiovascular risk.

Summary: Elevated phosphate in urine may indicate high intake of inorganic P salts from food additives. Elevated phosphate in plasma is linked to vascular dysfunction and calcification. This study explored the associations between phosphate in urine and plasma, estimated phosphate intake, and incidence of cardiovascular disease (CVD). It found that higher levels of urinary phosphate were associated with CVD and myocardial infarctions. Plasma phosphate showed a weaker association with CVD.

Summary: This study investigated the bacterial DNA signatures in the circulation of CKD patients and those receiving KTx treatment. The results suggest that dysbiosis increases as CKD progresses, accompanied by an increase in trimethylamine (TMA) producing pathobionts Pseudomonas and Bacillus. Surprisingly, KTx patients displayed a significantly different microbiota compared to CKD5 patients, with further increase in TMA producing Bacillus and loss of salutogenic Lactobacilli. Two genera (Veillonella and Saccharimonidales) showed significant differences in abundance following KTx, reflecting a reciprocal relationship between TMA producers and utilisers.

Summary: Two decades ago, the term chronic kidney disease-mineral and bone disorder (CKD-MBD) was coined to describe the abnormalities in biochemical, bone, and extra-skeletal calcification in patients with CKD. CKD-MBD is a prevalent complication that contributes to fractures, cardiovascular disease, loss of quality of life, and premature mortality. Current therapies targeting phosphate retention, vitamin D metabolism, and parathyroid hormone disturbances have been largely unsuccessful, calling for new approaches. The role of the gut microbiome, immune system, inflammation, and oxidative stress in CKD-MBD is explored in this review, along with potential therapeutic options.

Summary: This study examined the association of interleukin-6 (IL-6) and albumin levels with outcomes in chronic kidney disease (CKD) patients, using the IL-6 to albumin ratio (IAR) as a predictor of death risk in incident dialysis patients. The results showed that IAR had a higher discrimination for predicting all-cause mortality compared to IL-6 and albumin alone. Additionally, high and middle IAR tertiles were significantly associated with an increased risk of all-cause mortality.

Summary: Muscle fat infiltration (MFI), also known as myosteatosis, refers to the accumulation of lipids in the skeletal muscle. MFI is usually assessed using imaging methods like CT, MRI, and ultrasound, primarily in the legs, arms, and trunk muscle groups. MFI is considered a marker of muscle quality, where higher fat deposition in the muscle leads to decreased contraction power and force production per unit of muscle mass.
