Metabolites from mid-trimester plasma of pregnant patients at high-risk for preterm birth.

Am J Obstet Gynecol MFM 2021 May 12:100393. Epub 2021 May 12.

Institute for Environmental Health Solutions, Gillings School of Global Public Health, University of North Carolina-Chapel Hill, Chapel Hill, NC; Department of Environmental Sciences and Engineering, Gillings School of Global Public Health, University of North Carolina-Chapel Hill, Chapel Hill, NC.

Leap-2/ghrelin interplay in adult growth hormone deficiency: cause or consequence? A pilot study.

IUBMB Life 2021 May 15. Epub 2021 May 15.

Dipartimento di Sicurezza e Bioetica, Sezione di Farmacologia, Università Cattolica del Sacro Cuore - Fondazione Policlinico Universitario A. Gemelli IRCCS, Roma, Italia.

Ghrelin and its endogenous antagonist liver-expressed antimicrobial peptide-2 (LEAP-2) are involved in GH secretion and glucose/lipids metabolism. LEAP-2 expression in conditions of metabolic impairment may be upregulated, usually pairing with a concomitant reduction in ghrelin secretion. Adult growth hormone deficiency (aGHD) is characterized by insulin resistance, weight gain and increased fat mass. Read More

Residual β-cell function after 10 years of autoimmune type 1 diabetes: prevalence, possible determinants, and implications for metabolism.

Ann Transl Med 2021 Apr;9(8):650

National Clinical Research Center for Metabolic Disease, Key Laboratory of Diabetes Immunology, Ministry of Education, Department of Metabolism and Endocrinology, The Second Xiangya Hospital of Central South University, Changsha, China.

Background: Type 1 diabetes (T1D) has long been considered a progressive autoimmune disease resulting in the failure of pancreatic β-cell function and absolute endogenous insulin deficiency. However, several studies have demonstrated patients with T1D have detectable C-peptide levels long after diagnosis, which has remarkable clinical significance. Since this issue has not been systematically explored in non-Caucasian populations, we aimed to identify the prevalence of residual β-cell function and its related clinical features in Chinese long-term T1D patients.
