Intermittent hypoxemia (IH), a pathophysiologic consequence of obstructive sleep apnea (OSA), adversely affects insulin sensitivity, insulin secretion, and glucose tolerance. Nifedipine, an L-type calcium channel blocker frequently used for treatment of hypertension, can also impair insulin sensitivity and secretion. However, the cumulative and interactive repercussions of IH and nifedipine on glucose homeostasis have not been previously investigated.

Article Synopsis
  • HIV-associated cardiovascular disease (CVD) is becoming more common, but the reasons for this increased risk in people living with HIV (PWH) are not well understood, particularly regarding lipoprotein(a) [Lp(a)].
  • A study involving 65 PWH and 52 controls found that Lp(a) levels were significantly higher in PWH, and they showed lower coronary endothelial function (CEF) as measured by cardiac imaging.
  • The study concluded that elevated Lp(a) in PWH is linked to impaired CEF, suggesting that Lp(a) might contribute to the increased cardiovascular risk in this population.

Confounding results of engineered mesenchymal stem cells (MSCs) used as cellular vehicles has plagued technologies whereby success or failure of novel approaches may be dismissed or inaccurately ascribed solely to the biotechnology platform rather than suitability of the human donor. Polymeric materials were screened for non-viral engineering of MSCs from multiple human donors to deliver bone morphogenic protein-4 (BMP4), a protein previously investigated in clinical trials for glioblastoma (GBM) to combat a subpopulation of highly invasive and tumorigenic clones. A "smart technology" that target the migratory and stem-like nature of GBM will require: (1) a cellular vehicle (MSC) which can scavenge and target residual cells left behind after surgical debulking and deliver; (2) anti-glioma cargo (BMP4).

Fructose-1,6-bisphosphatase (FBPase) deficiency is a rare, inborn error of metabolism, that causes hypoglycemia and lactic acidosis in response to inadequate glucose intake and/or high intakes of fructose, sucrose, or sorbitol. Pregnancy in women with FBPase deficiency puts them at high risk for metabolic decompensation due to increased glucose demands from the growing fetus. Here we report a 31-year-old primipara who was treated starting at 14 weeks gestation with a diet high in complex carbohydrates and low in fructose, sucrose, and sorbitol and close monitoring of glucose levels throughout her pregnancy.
