RESUMEN
Context: Infertility affects more and more younger patients nowadays. Life-saving cancer treatments - chemotherapy and radiation therapy unfortunately damage oocytes and reduce the window of fertility in women. There were an estimated 14.1 million cases of cancer worldwide in 2012, of which 6.7 million were in women. Aim: We are reviewing fertility options and treatments for women fighting oncological diseases. It is important to promote that there is a possibility for these patients to know all they can do in order to preserve their fertility and our government should help all these young patients.The trend of delayed childbearing has increased worldwide duet o increased life costs, difficulty of finding a suitable partner and carier options, while the number of women facing a cancer diagnosis is rising. Material and methods: We describe a review regarding the impact of these treatments for the fertility of these patients. Results: Show that informed patients can better cope with their diagnostic and have a better prognosis. Conclusions: Improving survival rates and current data have created a new medical field oncofertility. The term was first introduced in 2015 and is being used all over clinics that treat young patients nowadays.
RESUMEN
152Eu was standardized within the frame of a BIPM international comparison. The solution was prepared and bottled by PTB. The ampoules were measured at BIPM in the SIR ionization chambers and then dispatched to the participating laboratories. In the Radionuclide Metrology Laboratory of IFIN-HH, the solution was standardized using a coincidence method with "beta-efficiency extrapolation" by foil absorption. A simple 4pi beta-gamma-coincidence system was used, with NaI(Tl) and 4piPC detectors. No significant impurities were found apart for 0.5% 154Eu. To obtain linear extrapolation plots, a "gamma-window" of 180-1500 keV was chosen. Dead-times of 10 micros were used. A combined uncertainty of 0.24% was obtained, mainly from the extrapolation procedure component.
RESUMEN
A beta-gamma coincidence system consisting of a 2pi plastic beta detector and a Ge(Li) detector, is described. Such a system allows for a drastic reduction of background (approximately 70 times) as well as of Minimum Detectable Activity (approximately 7 times). An integral background (50-1500 keV) of less than 0.1 cps is obtained. The difficulty of the method, otherwise simple and inexpensive, is the precise determination of beta detector efficiency.
