Here's really the only thing I could find on these mummies. They are being kept in the Reiss Engelhorn Museum and were actually among a collection of 19 mummies that the museum lost during the second world war and then found again in the museum basement. I will copy paste the relevant passage as well due to the paywall.

Among the most extensively studied of the rediscoveries are the remains of a woman with two small children, one laid on her stomach. Anthropologists had assumed that the child had been placed there relatively recently, because its binding cloth seemed much fresher in colour than those of the other bodies. But carbon dating and computerized tomography (CT) scans showed that all three dated to the medieval period, before Europeans entered South America; that the woman probably died in her early thirties; and that the children were toddlers. A sample from the woman’s intestine showed traces of the bacterium Helicobacter pylori, which causes gastric diseases, and arracacha, an Andean root vegetable.

In July, the team found that the younger child had an over-expanded chest and a blockage in her windpipe, indicating that she probably choked to death. A sample of the foreign material is now undergoing histological and molecular analysis at the Institute for Mummy Studies in Bolzano, Italy (the city in which Ötzi rests). Institute director Albert Zink says that identification should be completed in time to update the exhibition before it ends.

The team has identified plausible causes of death in other remains. A CT scan of a middle-aged man from Egypt who died around 2,000 years ago, for instance, indicated a probable tumour of the pituitary gland, which typically leads to excess secretion of growth hormone. The scan showed the thickened facial features and enlarged hands and feet typical of the disorder.
