Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: Context: This study was designed to examine the course of psychological distress and pain from study entry to death in 59 women with metastatic breast cancer participating in a randomized trial of the effects of group psychotherapy on psychosocial outcomes and survival. It was hypothesized that psychological distress would increase significantly before death independent of changes in pain.', 'Data were collected as part of a larger study (N = 125). Analyses were based on data from a subset of women who had died and for whom we had data from at least three assessments. Mean levels of mood, trauma symptoms, depression symptoms, well-being, and pain over three time points were examined: at baseline (T1), the second-to-last assessment before death (T2), and the last assessment before death (T3).', 'Results indicate that while psychological distress remained relatively constant or declined from T1 to T2, means on all measures significantly changed in the hypothesized direction from T2 to T3. Neither self-reported pain, nor the passage of time, appeared to account for these changes. Additionally, participation in group psychotherapy did not have a significant impact on this change in distress proximal to death.
Answer: Results suggest that specialized end-stage clinical interventions are particularly needed for cancer patients as they approach death. Moreover, intervention studies for patients with deteriorating illnesses may need to take this "spike" in psychological distress and pain proximal to death into account to avoid Type II errors in evaluations of psychological outcomes.

Output: Do psychological distress and pain significantly increase before death in metastatic breast cancer patients?


Input: Consider Input: Context: To test the role of mast cells in gut inflammation and colitis using interleukin (IL)-10-deficient mice as an experimental model.', 'Mast cell-deficient (Kit (W-sh/W-sh) ) mice were crossbred with IL-10-deficient mice to obtain double knockout (DKO) mice. The growth, mucosal damage and colitis status of DKO mice were compared with their IL-10-deficient littermates.', 'DKO mice exhibited exacerbated colitis compared with their IL-10-deficient littermates, as shown by increased pathological score, higher myeloperoxidase content, enhanced Th1 type pro-inflammatory cytokines and inflammatory signaling, elevated oxidative stress, as well as pronounced goblet cell loss. In addition, deficiency in mast cells resulted in enhanced mucosal damage, increased gut permeability, and impaired epithelial tight junctions. Mast cell deficiency was also linked to systemic inflammation, as demonstrated by higher serum levels of tumor necrosis factor α and interferon γ in DKO mice than that in IL-10-deficient mice.
Answer: Mast cell deficiency in IL-10-deficient mice resulted in systematic and gut inflammation, impaired gut barrier function, and severer Th1-mediated colitis when compared to mice with only IL-10-deficiency. Inflammation and impaired gut epithelial barrier function likely form a vicious cycle to worsen colitis in the DKO mice.

Output: Does mast cell deficiency exacerbate inflammatory bowel symptoms in interleukin-10-deficient mice?


Input: Consider Input: Context: Accurate diagnosis of egg allergy by IgE testing is challenged by a large number of atopic subjects sensitized, but clinically tolerant to eggs. In addition, discrimination between allergy to raw only, or raw and cooked egg allergy is important. In this study, we investigate the diagnostic performance of IgE tests to native and denatured egg proteins.', 'According to food challenges and clinical tolerance, study subjects were randomized to the following groups: (Group A) sensitized but clinically tolerant to egg, (Group B) allergic to raw egg only, or (Group C) allergic to raw and cooked egg. Serum-specific IgE to native or reduced and oxidized egg white, ovomucoid, and ovalbumin were measured.', 'Increasing titers of specific IgE to the various proteins were found according to the degree of the egg allergy. Cut-off values for IgE testing to native egg could be determined to distinguish between raw egg allergic and egg-tolerant subjects (1.6 kU/l), as well as raw and cooked egg allergic and egg-tolerant subjects (4.1 kU/l). ROC curves analysis showed that native ovalbumin was the best test for the diagnosis of allergy to raw and cooked egg, and native ovomucoid was best to distinguish between allergy to raw only, and allergy to raw and cooked egg. Sequential testing improved the diagnosis, when in addition to IgE to native egg white, IgE to native ovalbumin was tested for the diagnosis of raw and cooked egg allergy, and IgE to native ovomucoid for the discrimination between allergy to raw only, or to raw and cooked eggs.
Answer: The diagnosis of egg allergy can be significantly improved using a panel of IgE tests to egg proteins in the native or denatured form. The accuracy can be improved using combined IgE testing.


Output: Do native and denatured egg white protein IgE tests discriminate hen 's egg allergic from egg-tolerant children?
