question:
Question: Are immunologic marker paths for seroconversion : single determinations of immunoglobulin A and beta 2-microglobulin adequate to estimate time of HIV infection . Multicohort Analysis Project Workshop . Part II?
Answer: Further study of how serum IgA reflects HIV infection and careful clinical and statistical assessment of reduced beta 2M from 5 or 6 years after HIV infection are needed. The dependence of marker paths on mode of HIV transmission suggests that sexual transmission may have implications for HIV disease progression. The feasibility of using serum IgA and beta 2M, evaluable in single stored blood samples, to estimate time of HIV infection has been set back by our results.
answer:
no


question:
Question: Is hyperglycemia associated with increased risk of patient delay in pulmonary tuberculosis in rural areas?
Answer: Patient delay appears to be a serious problem in this rural area with a high prevalence of tuberculosis. Hyperglycemia is independently associated with an increased probability of patient delay, which, in turn, may result in more serious clinical manifestations.
answer:
yes


question:
Question: Is hSP expression in human leukocytes modulated by endurance exercise?
Answer: Strenuous exercise increased HSP expression in blood immediately after the run, indicating a protective function of HSP in leukocytes of athletes to maintain function after heavy exercise. The downregulation of HSP-positive cells in trained athletes at rest seems to be a result of adaptation mechanisms to regular endurance training.
answer:

yes
