Michael Somogyi (Somogyi Mihály, 1883-1971) was a Hungarian biochemist who developed his scientific career in Europe and, primarily, the United States. He gave the name to the eponymous Somogyi effect or Somogyi hypothesis (in short, rebound hyperglycemia after insulin-induced hypoglycemia, particularly nocturnal), which was an axiom in the treatment of diabetes for decades. Although it is currently debated whether the Somogyi hypothesis is a real or relevant phenomenon in patients with diabetes, Somogyi's other significant career achievements are often overlooked.

Maple syrup urine disease (MSUD) is a rare inherited metabolic disorder characterized by deficient activity of the branched-chain alpha-ketoacid dehydrogenase (BCKDH) complex, required to metabolize the amino acids leucine, isoleucine, and valine. Despite its profound metabolic implications, the molecular alterations underlying this metabolic impairment had not yet been completely elucidated. We performed a comprehensive multi-omics integration analysis, including genomic, epigenomic, and transcriptomic data from fibroblasts derived from a cohort of MSUD patients and unaffected controls to genetically characterize an MSUD case and to unravel the MSUD pathophysiology.

Article Synopsis
  • Myxedema coma often involves reduced consciousness and low body temperature, potentially linked to thyroid issues, especially in patients with head trauma and central hormone deficiencies.
  • A 52-year-old man with head trauma exhibited symptoms like drowsiness and hypotension, with initial tests showing normal TSH levels but low ACTH and FT4, and his condition worsened before improving with medication.
  • The case highlights the importance of assessing both TSH and FT4 levels for diagnosing central hypothyroidism, as relying solely on TSH might lead to overlooked conditions in patients showing hormone deficiency symptoms post-trauma.

The In-between: Time to Talk About Bronchiectasis in Adolescents and Their Transition to Adult Care.

Arch Bronconeumol

September 2024

Pneumology Department, Hospital Universitari Vall d'Hebron, Vall d'HebronInstitut de Recerca (VHIR), Vall d'Hebron Barcelona Hospital Campus, Barcelona, Spain; Centre for Biomedical Network Research on Respiratory Diseases (CIBERES), Instituto de Salud Carlos III, Madrid, Spain. Electronic address:

Paediatric and adult bronchiectasis patients have been addressed in the literature as two different populations due to several differences, but there is insufficient evidence to understand how and when disease characteristics really change along patients' lifespan. This lack of knowledge is evident in all aspects of the transition: insufficient data is available about radiology, lung function, microbiology and treatment, and only limited information is currently available about changes in clinical presentation and psychosocial aspects. For instance, symptoms seem to improve during the third and fourth decades of life, a period sometimes referred to as the "honeymoon phase".

Role of CYP2D6 and CYP3A4 polymorphisms on aripiprazole and dehydroaripiprazole concentrations in patients undergoing long-acting treatment.

Prog Neuropsychopharmacol Biol Psychiatry

December 2024

Pharmacy Department, University Clinical Hospital Santiago de Compostela (CHUS), Spain; Clinical Pharmacology Group, Health Research Institute of Santiago de Compostela (IDIS), Spain. Electronic address:

Aripiprazole once-monthly (AOM) exhibits an important interindividual pharmacokinetic variability with significant implications for its clinical use. CYP2D6 and CYP3A4 highly contributes to this variability, as they metabolize aripiprazole (ARI) into its active metabolite, dehydroaripiprazole (DHA) and the latter into inactive metabolites. This study aims to evaluate the effect of CYP2D6 and CYP3A4 polymorphisms in combination and the presence of concomitant inducers and inhibitors of this cytochromes on ARI and DHA plasma concentrations in a real clinical setting.
