General, however, the risk of damage from medical imaging is usually proportional to the radiation dosage and the gestational age group of the embryo or fetus, the study authors said. If a patient requires multiple scans and repeated doses of radiation, a consultation with a qualified medical physicist is highly recommended to determine estimated fetal dose, Matzon and his co-workers concluded in the news headlines release..

The supplements also appeared to reduce the numbers of thick, scaly patches of skin that may become cancer. Those patches were low in the nicotinamide group by 11 % at three months, and by 20 % at nine a few months of treatment. Nevertheless, those benefits quickly disappeared through the study’s follow-up period. ‘When people halted taking their tablets after 12 months, the benefit was no seen,’ Damian said. ‘Put simply, you need to continue acquiring the tablets to allow them to be effective.’ Nicotinamide did not appear to cause any longer adverse events compared to the placebo, the researchers added.
