Characteristics of Young Women Presenting With Acute Myocardial Infarction: The Prospective, Multicenter, Observational Young Women Presenting Acute Myocardial Infarction in France Study.

Background: The percentage of women <50 years of age hospitalized with myocardial infarction is increasing. We describe the clinical, morphological, and biological characteristics, as well as the clinical outcomes of this population.

Methods And Results: This prospective, observational study included consecutive women <50 years of age admitted for myocardial infarction at 30 centers in France (May 2017-June 2019).

Highly weathered mineral soils have highest transfer risk of radiocaesium contamination after a nuclear accident: A global soil-plant study.

Accidental release of radiocaesium (Cs) from nuclear power plants may result in long-term contamination of environmental and food production systems. Assessment of food chain contamination with Cs relies on Cs soil-to-plant transfer data and models mainly available for regions affected by the Chornobyl and Fukushima accidents. Similar data and models are lacking for other regions.

Differentiation between chemo- and radiotoxicity of Cs and Co on Lemna minor.

The uptake and effects of stable Cs and Co on L.minor were extensively studied, together with the effects of gamma radiation using a Cs or Co source. Innovative is that we combined external irradiation (from Cs or Co sources) with the direct uptake of certain amounts of stable Cs or Co to simulate the impact of the same mass of a radioisotope compared with that of the stable element.

Lack of evidence that progesterone in ovulatory cycles causes breast cancer.

A recent Perspective article asserted that progesterone secretion during ovulatory cycles is the cause of breast cancer. However, we challenge most of the evidence developed in this publication. First, there is a lack of evidence that progesterone is mutagenic for breast cells.
