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.

[Q]: Context: Anorectal manometry provides objective information about anorectal function, but its results depend on the examiner's skill, the type of equipment, and subject characteristics like age or gender. This single institution, prospective study was performed to investigate the effect of gender and age on the results of anorectal manometry.", 'All included subjects completed a questionnaire to assess their bowel function. The survey included 13 validated questions (eight on constipation and five on incontinence) and was used to exclude subjects with pathological constipation or incontinence. Subjects with normal bowel function underwent anorectal manometry to measure anal sphincter length (ASL), maximum resting pressure (MRP), and maximum squeeze pressure (MSP), and the results were compared by gender and age.', 'The mean age of the 154 participants (94 male and 60 female) was 59.1 years. ASL was greater in men (4.23 vs. 3.85 cm, p\u2009<\u20090.001). MRP was not significantly different according to gender (p\u2009=\u20090.93), but MSP was higher in men (190.18 vs. 116.49 mmHg, p\u2009<\u20090.001). ASL did not correlate with age (p\u2009=\u20090.707). MRP was inversely related to age in both men (R (2)\u2009=\u20090.152, p\u2009<\u20090.001) and women (R (2)\u2009=\u20090.282, p\u2009<\u20090.001), and MSP only in women (R (2)\u2009=\u20090.210, p\u2009<\u20090.001).
Answer: Anorectal manometric parameters are influenced by gender and age. This should be taken into consideration when interpreting manometric readings in a clinical setting.
[A]: Are anorectal manometric parameters influenced by gender and age in subjects with normal bowel function?


[Q]: Context: The present study investigated how parents and peers interact in promoting or delaying Dutch adolescents' sexual initiation and intention and focused specifically on parents as moderators of peer influence.", "Using a longitudinal design, two waves of online questionnaire data were collected among 900 Dutch adolescents (M = 13.8 years at T1), who were sexually inexperienced at baseline. At T1, participants reported on three types of perceived sexual peer norms: friends' sexual behaviors (descriptive norms), friends' sexual attitudes (injunctive norms), and experienced peer pressure to have sex. They also rated two parenting aspects at T1: the general quality of their relationship with parents and the frequency of sexuality-specific communication with their parents. Six months later, the participants reported on their experience with different sexual behaviors ranging from naked touching or caressing to intercourse and their intention to have sex in the next school year.", "Relationship quality with parents was significantly associated with both outcomes, with a higher relationship quality predicting smaller odds of sexual initiation and less intention to have sex. Two significant interaction effects showed that frequent sexual communication with parents significantly reduced the effects of sexually active friends and experienced peer pressure on adolescents' intention to have sex.
Answer: Our findings show that different types of sexual peer norms and both general and sexuality-specific parenting play an important role in the early stages of Dutch adolescents' sexual trajectories. Moreover, parent-adolescent communication about sexuality can function as a buffer for the sex-stimulating effects of sexual peer norms.
[A]: Do parents as moderators of longitudinal associations between sexual peer norms and Dutch adolescents ' sexual initiation and intention?


[Q]: Context: Myeloperoxidase (MPO) -containing macrophages and neutrophils have been described at sites of plaque rupture. The presence of these cells in precursor lesions to acute rupture (thin cap atheroma, or vulnerable plaque) and within thrombi adjacent to ruptures has not been described, nor an association with iron-containing macrophages within unstable plaques.', "We studied 61 acute ruptures, 15 organizing ruptures, 31 thin cap fibroatheromas, and 28 fibroatheromas from 72 sudden coronary death victims by immunohistochemical and histochemical techniques. Inflammatory cells were typed with anti-CD68 (macrophages), anti-BP-30 (neutrophil bactericidal glycoprotein), and anti-MPO. Iron was localized by Mallory's Prussian blue stain. In selected plaques alpha smooth muscle actin (DAKO, Carpinteria, CA, clone M0851) was performed.", 'MPO positive cells were present in 79% of ruptured caps, 28% of thin cap fibroatheroma, and no fibroatheromas; neutrophils were present in 72% of ruptures, 8% of thin cap fibroatheromas, and no fibroatheromas. Iron containing foam cells were present in the caps of 93% of acute ruptures, of 85% of organizing ruptures, 20% of thin cap atheromas, and 10% of fibroatheromas. MPO positive cells were more frequent in occlusive than non-occlusive thrombi adjacent to ruptures (p = .006) and were more numerous in diabetics compared to non-diabetics (p = .002)
Answer: Unstable fibrous caps are more likely to contain MPO-positive cells, neutrophils, and iron-containing macrophages than fibrous caps of stable fibroatheromas. MPO-positive cells in thrombi adjacent to disrupted plaques are associated with occlusive thrombi and are more numerous in diabetic patients.

Do monocytes and neutrophils expressing myeloperoxidase occur in fibrous caps and thrombi in unstable coronary plaques?
