Evaluation of serum insulin-like growth factor 1 concentrations in non-diabetic cats with chronic kidney disease.

Feline hypersomatotropism (HST) can develop in both diabetic and non-diabetic cats, but studies evaluating the prevalence of HST in cats without diabetes mellitus (DM) are lacking. The aims of the study were to evaluate circulating insulin-like growth factor 1 (IGF-1) in non-diabetic cats with chronic kidney disease (CKD), to assess whether there is a correlation between general test of renal function and IGF-1 concentration in cats with CKD, and to screen this population for the presence of HST. In this prospective study, one hundred fifty-four non-diabetic cats (n = 154) with CKD from referral centers in Buenos Aires (Argentina) were evaluated.

Increased insulin-like growth factor 1 concentrations in a population of non-diabetic cats with overweight/obesity.

Feline hypersomatotropism (HST) is typically associated with diabetes mellitus (DM), whereas HST without concurrent DM has only been reported in a few cases. Weight gain may be observed in cats with HST. The aims of this study were to evaluate circulating insulin-like growth factor-1 (IGF-1) in non-diabetic cats with overweight/obesity, to screen this population for the presence of HST, and to assess whether there is a correlation between body weight/body condition score (BCS) and serum IGF-1 concentration in overweight/obese cats.

Prevalence of hypersomatotropism and hyperthyroidism in cats with diabetes mellitus from referral centers in Buenos Aires (2020-2022).

Objectives: The aim of this study was to estimate the prevalence of hypersomatotropism (HST) and hyperthyroidism in cats with diabetes mellitus (DM) from referral centers in Buenos Aires, Argentina.

Methods: This was a prospective study. Systematic screening of serum insulin-like growth factor 1 (IGF-1) and total thyroxine was performed in all cats diagnosed with DM at referral centers in Buenos Aires between February 2020 and February 2022.

Extra-Neural Metastases From Primary Intracranial Ependymomas: A Systematic Review.

Background: Primary intracranial ependymomas (IE) are rare brain tumors rarely metastasizing outside the central nervous system. We systematically reviewed the literature on extra-neural metastases from primary IEs.

Methods: PubMed, Scopus, Web-of-Science, and Cochrane were searched following the PRISMA guidelines to include studies of extra-neural metastases from primary IEs.
