Summary: This study identified nine pathogenic variants in the BCKDHA, BCKDHB, and DBT genes in six MSUD families, including two novel pathogenic variants in the BCKDHB gene, which enriched the genetic mutational spectrum of the disease. High-throughput sequencing is essential for the differential diagnosis, early treatment, and prenatal diagnosis of MSUD.

Summary: Maple syrup urine disease (MSUD) is a metabolic disorder that affects the digestion and processing of proteins necessary for growth. An intelligent dietary tool called MSUD Baby Buddy has been developed to assist caregivers of MSUD patients in tracking amino acid intake from baby formulas. The tool uses a knowledge-based system to provide accurate recommendations based on patient data and formula preferences. MSUD Baby Buddy aims to maintain proper amino acid levels and reduce the need for frequent visits to medical professionals.

Summary: Maple syrup urine disease (MSUD) is a metabolic disorder caused by deficient BCKD enzymatic complex activity. This study identified novel pathogenic mutations in BCKDHA, BCKDHB, and DBT genes in Chilean MSUD patients, and found no correlation between genotype and phenotype. Early diagnosis through newborn screening may help establish genotype-phenotype relationships more efficiently.

Summary: Maple syrup urine disease (MSUD) is a metabolic disorder caused by the inadequate breakdown of branched-chain amino acids. This is due to pathogenic variants in BCKDHA, BCKDHB, DBT, or DLD genes, which encode subunits of the branched-chain alpha-ketoacid dehydrogenase complex. In this study, we report a patient with MSUD carrying a novel homozygous start-loss variant in the PPM1K gene, highlighting the role of PPM1K variants in causing mild MSUD.

Summary: Overconsumption of fructose and childhood overweight are closely related to the development of pediatric NAFLD. However, their role in the early onset and progression of NAFLD in the allograft remains to be established. Furthermore, further research is needed to study the possible interaction between a BCAA imbalance and dietary intake in the development of NAFLD.

Summary: Maple Syrup Urine Disease (MSUD) is a metabolic disorder caused by deficiency in an enzyme complex, leading to the accumulation of certain amino acids. This study demonstrates that chronic administration of these amino acids can induce depressive-like behavior in rats, as well as alter neurotrophin levels. However, treatment with an antidepressant drug can prevent these behavioral changes and restore neurotrophin levels.

Summary: Maple syrup urine disease (MSUD) is a rare autosomal-recessive disorder caused by a deficiency of a specific enzyme. This leads to the accumulation of BCAAs in the body, resulting in various symptoms such as feeding problems, vomiting, lethargy, and irritability. If left untreated, it can lead to seizures, coma, and death. Blood and urine analysis can detect the accumulation of BCAAs.

Summary: Maple syrup urine disease (MSUD) is an autosomal recessive inherited metabolic disorder caused by BCKD deficiency, leading to toxic accumulation of BCAAs. Diagnosis is usually based on specific chemical testing in plasma and urine, with brain MRI results helping to confirm the disorder quickly.

Summary: Since 1972, 18 patients with neonatal-onset maple syrup urine disease (MSUD) have been detected by newborn bloodspot screening (NBS) in Ireland. Treatment has been based on early implementation of emergency treatment, diet, close monitoring, and even dialysis in the setting of acute metabolic decompensation. Early diagnosis and skilled multidisciplinary team management are crucial for achieving good outcomes for patients.

Summary: This study reports on a newly observed hierarchical SPIONs nanostructure, known as nanobundles, which possess magnetic and bundle-like morphology. Nanobundles were synthesized through colloidal chemical processes and sol-gel synthesis, where core-shell structured nanoclusters of nanoparticles were formed through magnetic assembly and self-assembly processes. These nanobundles show great potential in various fields such as medical imaging, magnetic separation, photonic crystals, and magnetic liquid manipulation.

Summary: Behavioral strategies require control of impulsive responses, but the neural basis of natural variation in impulsivity between individuals remains unknown. This study identified the subthalamic nucleus as a major hotspot for impulsivity and found that the subthalamic nucleus circuitry multiplexes motor control and trait impulsivity, which are molecularly dissociated by mGlu4.
