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.

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.

Context: To examine the concentration of C-reactive protein (CRP) in relation to gestational weeks during pregnancy among Chinese women.', 'From a randomized control trial of prenatal supplementation with folic acid, iron-folic acid, and multiple micronutrients in China, we examined 834 pregnant women with CRP measured initially between 5 and 20 weeks and at follow-up between 28 and 32 weeks gestation. We calculated and plotted CRP geometric means by gestational weeks. The same analysis was repeated for women who had normal pregnancies (624 women) by excluding women with stillbirth, preterm, small for gestational age, body mass index <18.5 kg/m(2) or >30 kg/m(2) at enrollment, and hypertension or anemia during pregnancy.', 'We observed a significant positive trend between log-transformed CRP and gestational age from 5 to 20 weeks and from 28 to 32 weeks both in the full sample and in the subset of women who had normal pregnancies. CRP geometric mean was 0.81 mg/l at 5-7 weeks of gestation, 2.85 mg/l at 19-20 weeks of gestation, and 3.89 mg/l at 32 weeks of gestation. A similar increasing trend in the CRP median or percentage of elevated CRP were also observed.
Answer: We concluded that CRP increased with gestational age among healthy Chinese women who delivered healthy infants. Am. J. Hum. Biol. 28:574-579, 2016. ©️ 2016 Wiley Periodicals, Inc.

Context: To compare histologically the size and appearance of capsule disks after femtosecond laser-assisted cataract surgery and conventional cataract surgery.', 'In 100 eyes of 100 patients with visually significant cataracts, a femtosecond laser capsulotomy or a capsulorhexis with an aimed diameter of 5.0 mm was performed by one experienced surgeon. The diameter, area, circularity, and cut quality was histologically examined with light microscopy and scanning electron microscopy.', 'The mean diameter of the manual and the femtosecond laser capsule disk group were not statistically significantly different (manual 4.91 0.34; femtosecond: 4.93 0.03; p = 0.58). The mean area of the capsule disks was 18.85 2.69 mm2 in the manual and 19.03 0.26 mm2 in the femtosecond group (p = 0.64). The capsules of the femtosecond group (0.95 0.02) were significantly more circular than the ones of the manual group (0.81 0.07; p&lt;0.0001). The femtosecond laser capsule disks displayed a more saw blade-like structure created through the single laser spots. The histologic examination combined with prospective video analysis revealed respiratory movement of the eye during the capsulotomy as a potential risk factor for redial tears.
Answer: Femtosecond laser can perform a capsulotomy with high reliability. In comparison to a highly experienced cataract surgeon, the achieved results in size are similar. In terms of circularity, the femtosecond laser was superior the manual procedure. Better refractive outcomes based on a 360-degree optic overlap seem to be possible, especially for less experienced surgeons.
