Background: Thrombospondin-2 (TSP2) is a matricellular protein with tissue expression induced by hyperglycaemia. TSP2 has been implicated in non-diabetic renal injury in preclinical studies and high circulating levels were associated with worse kidney function in cross-sectional clinical studies. Therefore, we investigated the prospective associations of circulating TSP2 level with kidney function decline and the trajectories of estimated glomerular filtration rate (eGFR) in type 2 diabetes.

Aims: Adipocyte fatty acid-binding protein (AFABP) is associated with cardiovascular diseases in type 2 diabetes. Whether circulating AFABP levels are associated with the risk of heart failure (HF) in type 2 diabetes remains undefined. We investigated the prospective association of circulating AFABP levels with incident HF hospitalization in type 2 diabetes, and its relationship to the use of sodium glucose co-transporter 2 inhibitors (SGLT2i) which reduce HF risk.

Aims: Sexual dimorphism has been reported in the epidemiology, neurobiologic susceptibility and clinical presentation of Alzheimer's disease (AD). As poor glycaemic control is associated with increased risks of AD, we aimed to investigate whether glycaemia-related risk factors also differ between men and women, using a retrospective, sex-specific analysis of a large Chinese cohort with diabetes.

Materials & Methods: A total of 85,514 Chinese individuals with type 2 diabetes (T2D; 46,783 women and 38,731 men), aged ≥60 years, were identified from electronic health records and observed for incident AD.

Article Synopsis
  • Adiponectin, often seen as beneficial for heart health, surprisingly correlates with higher rates of cancer and mortality in diabetes patients, despite its positive effects shown in lab studies.
  • A study involving 5,658 type 2 diabetes patients found that those with higher serum adiponectin levels were more likely to develop cancer and have cancer-related deaths over a median follow-up of 6.5 years.
  • The research revealed that for each doubling of adiponectin concentration, the risks for developing cancer and dying from cancer increased, indicating the complexity of adiponectin's role in diabetes and health outcomes.

Article Synopsis
  • Elevated levels of adipocyte fatty acid-binding protein (AFABP) in serum are linked to the progression of diabetic kidney disease (DKD), though whether this is due to AFABP's role in kidney damage or due to decreased clearance in DKD patients is unclear.
  • A study involving 5,454 Chinese participants with type 2 diabetes measured serum AFABP levels and tracked adverse renal outcomes over five years, finding that higher AFABP levels were significantly correlated with worsening kidney conditions.
  • These findings suggest that AFABP could serve as an important early marker for identifying individuals at risk of developing severe renal issues in DKD, regardless of their baseline kidney function.

Introduction: Raised circulating adipocyte fatty acid-binding protein (AFABP) concentrations are associated with various adverse health conditions. However, their relationship with mortality remains to be defined, especially in view of the sexual dimorphism of circulating AFABP concentrations. Here we investigated prospectively whether serum AFABP concentrations predict multiple mortality outcomes in men and women alike, using a large clinic-based cohort of individuals with type 2 diabetes, a condition with raised AFABP concentrations.
