What is the impact on metabolism and fertility of the medical treatments for obesity and bariatric surgery? We have reviewed this topic in our manuscript at @MetabolitesMDPI journal #obesity #weightloss #endocrinology mdpi.com/3263072

Excited to share our new publication from my previous lab, where we evaluated treatment-resistant lactotroph pituitary neuroendocrine tumors using spatial transcriptomics. actaneurocomms.biomedcentral.com/articles/10.11…

@Alecman98 @ECFMG_IMG Congratulations!!

@alberto_guijosa @DanaFarber @harvardmed Muchas Felicidades!!!

Just landed back from #ASH2024 to get my Step 2 score!! The past months balancing research fellowship @DanaFarber @harvardmed and Step 2 prep were tough, but I’m deeply grateful to my mentors, friends, and family for their support and motivation every step of the way.

Excited to share our study @AJKDonline, revealing the underrepresentation of LMICs in 20 years of CKD drug RCTs (1,366 trials, 301,158 participants). We found a strong positive correlation between RCT participation and the Human Development Index, health expenditure, and R&D expenditure. As a Mexican medical graduate, I’m hopeful this work draws attention to the need for more inclusive global research. buff.ly/3ZL2Q1h
