Preclinical models in oncological pharmacology: limits and advantages
A wide range of experimental tumor models, each with distinct advantages and disadvantages, is nowadays available. Due to the inherent differences in their complexity and functionality, the choice of the model is usually dependent on the application. Thus, to advance specific knowledge, one has to choose and use appropriate models, which complexity is largely dependent on the hypotheses to test, that is on the objectives. Whatever the model chosen, the complexity of cancer is such that none of them will be able to fully represent it. In vitro tumor models have provided important tools for cancer research and still serve as low-cost screening platforms for drugs. The improved understanding o…
Body Mass Index and Weight Gain in Pregnant Women With HIV: A National Study in Italy.
Although most of the women (69.4%) had a normal BMI at start of pregnancy, only 37% had an adequate weight gain during pregnancy. Inadequate body weight gain was more common (44.8%) than excessive weight gain (18.2%), but 40% of overweight women and 50% of obese women had an excessive weight gain in pregnancy, with about 9% of the women in these categories gaining >18 kg during pregnancy (Table 1). Only 1.9% of the women had a vaginal delivery; elective and nonelective cesarean deliveries accounted for 81.3% and 16.7% of deliveries, respectively. Compared to underweight/normal women, overweight/obese women had similar occurrences of preterm delivery (23.4% vs 22.7%, P = .871), significantly…
