Paternal smoking, obesity can harm unborn babies

Publisher’s rating: Researchers have identified notable associations between paternal factors and birth outcomes, encompassing preterm birth, low birth weight, small for gestational age (SGA), and high birth weight prevalences. Contrary to popular belief, the placenta and foetus are not solely molded by the mother’s genetic blueprint and lifestyle choices. Studies demonstrate the substantial influence of the father’s genes and habits in the development of a healthy baby.

Es ist wissenschaftlich belegt, dass Masken in der Covid-Pandemie nichts gebracht haben.

Publisher’s rating: Mehrere wissenschaftliche Studien bestätigen eine Schutzwirkung durch Gesichtsmasken. Masken verringern nachweislich die Übertragungsrate von Sars-CoV-2 und dienen vor allem als Fremdschutz.

The review says studies find that masks reduce the transmission of SARS-CoV-2, chiefly by protecting other people from infection. It notes that masks can also limit physical capacity and that effectiveness depends on the concentration of virus in the air; it recommends combining measures to reduce infection risk.

It notes that excess sugar may contribute to obesity, a cancer risk factor, and may be associated with insomnia and premature skin aging.

Chá de folha de mamão cura a dengue

La Croix-Rouge américaine demande maintenant aux donneurs de sang vaccinés contre le Covd-19 de les appeler pour déterminer s'ils sont toujours éligibles.

Publisher’s rating: Ces affirmations sont infondées. La question relative à la vaccination contre le Covid-19 n'est liée qu'à la période d'attente entre vaccination et don – pour des raisons relatives aux anticorps. De manière générale, les personnes vaccinées sont appelées à donner leur sang pour faire face aux besoins actuels des banques du sang.

The review says the claim is unfounded: vaccinated people can donate blood, and the Red Cross encourages donors to come forward. It explains that vaccination questions are asked to establish eligibility, since some vaccines may require a waiting period; for Covid-19 vaccines, the FDA allows donation without a waiting period if the donor feels well and has no symptoms.
