Mitophagy, a selective clearance of damaged or superfluous mitochondria via autophagy machinery and lysosomal degradation, is an evolutionarily conserved process essential for various physiological functions, including cellular differentiation and immune responses. Defects in mitophagy are implicated in numerous human diseases, such as neurodegenerative disorders, cancer, and metabolic conditions. Despite significant advancements in mitophagy research over recent decades, novel and robust methodologies are necessary to elucidate its molecular mechanisms comprehensively.

  • Kidney disease (KD) is a serious complication of type 2 diabetes mellitus (T2DM), leading to increased risks of kidney failure and other serious health issues.
  • A study involving 252 T2DM patients revealed that while many received dietary guidance, only a small fraction actually adhered to recommended diets, with 31% of participants diagnosed with KD despite only 6% believing they had it.
  • The findings indicate a concerning lack of awareness about KD and underscore the need for better education on healthy lifestyles and regular screenings among T2DM patients to mitigate health risks.

  • Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disorder often leading to end-stage renal disease, and this study reviews native nephrectomy (NN) practices over 25 years at a transplant center.
  • A total of 89 out of 152 ADPKD patients who underwent kidney transplantation (KT) also had NN, with most NN being unilateral and planned surgeries showing better outcomes than acute ones.
  • The findings highlight the importance of careful planning and patient-specific strategies in NN for ADPKD due to increased complications associated with acute surgeries.

Article Synopsis
  • - The study aimed to address inconsistencies in diagnosing cerebral palsy (CP) among child neurologists and neurodevelopmentalists, focusing on their uncertainties surrounding the 2006 definition of CP.
  • - A survey conducted at the 2022 Child Neurology Society Annual Meeting revealed that 88% of respondents were uncertain about applying the 2006 definition, particularly regarding age of symptom onset and meaning of "nonprogressive."
  • - The authors propose four clarifications to the 2006 definition to improve diagnosis, emphasizing that motor symptoms should be observed by age 2 and that CP can be diagnosed earlier.

Background: Delays in early social and executive function are predictive of later developmental delays and eventual neurodevelopmental diagnoses. There is limited research examining such markers in the first year of life. High-risk infant groups commonly present with a range of neurodevelopmental challenges, including social and executive function delays, and show higher rates of autism diagnoses later in life.

Adenosine triphosphate (ATP) is a universal energy molecule and yet cells release it and extracellular ATP is an important signalling molecule between cells. Monitoring of ATP levels outside of cells is important for our understanding of physiological and pathophysiological processes in cells/tissues. Here, we focus on pancreatic beta cells (INS-1E) and test the hypothesis that there is an association between intra- and extracellular ATP levels which depends on glucose provision.
