question:
Question: Are factors associated with HIV infection the same for all women?
Answer: Factors vary in importance and significance of association with HIV infection in different subpopulations of women resident in Great Britain. This diversity is also likely to occur in other populations. It is important to identify these differences between subpopulations. Prevention and control policies and activities for HIV/AIDS cannot treat all women as if they were the same.

no


question:
Question: Is mortality in patients with non-functioning pituitary adenoma increased : systematic analysis of 546 cases with long follow-up?
Answer: Despite the improvement of treatments over the last three decades, the mortality of patients with NFAs in our series remains high. Apart from age, factors related with the management/outcome of the tumor are not independent predictors, and pituitary hormone deficits managed with the currently-used substitution protocols do not adversely affect mortality.
answer:

yes
