In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[EX Q]: Context: Excessive infant crying, or infantile colic, is a common and often stress-inducing problem for parents that can ultimately result in child abuse. From previous research it is known that maternal depression is related to excessive crying, but so far little is known about the influence of paternal depression.', "In a prospective, population-based study, we obtained information on both maternal and paternal depressive symptoms at 20 weeks of pregnancy by using the Brief Symptom Inventory. Parental depressive symptoms were related to excessive crying in 4426 two-month-old infants. The definition of excessive crying was based on the widely used Wessel's criteria (ie, crying >3 hours for >3 days in the past week).", 'After adjustment for depressive symptoms of the mother and relevant confounders, we found a 1.29 (95% confidence interval: 1.09-1.52) higher risk of excessive infant crying per SD of paternal depressive symptoms.\Question: Are paternal depressive symptoms during pregnancy related to excessive infant crying?
[EX A]: Our findings indicate that paternal depressive symptoms during pregnancy might be a risk factor for excessive infant crying. This finding could be related to genetic transmission, interaction of a father with lasting depressive symptoms with the infant, or related indirectly through contextual stressors such as marital, familial, or economic distress.

[EX Q]: Context: Globally, heterosexual intercourse is the primary route of HIV-1 (HIV) transmission. It follows that mechanisms that protect against HIV infection are likely operative at the genital mucosa. In HIV-resistant Kenyan sex workers who are highly exposed to HIV infection yet remain uninfected, protection correlates with HIV-specific immune responses and genetic factors. However, these factors do not entirely explain this model of natural immunity to HIV. We hypothesized that protection may be mediated by innate immune proteins in the genital tract of HIV-resistant sex workers.', 'The genital proteome of mucosal secretions from HIV-resistant women was examined using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry. Cervical lavage samples were collected from 315 HIV-resistant, HIV-uninfected and HIV-infected commercial sex workers.', 'Univariate analysis identified a 6 kDa biomarker of HIV resistance in genital secretions from these women. This protein was identified by tandem mass spectrometry as elafin and was found to be overexpressed in HIV-resistant women compared with HIV-uninfected (P = 0.001) and infected (P = 0.002) women. The elevated levels of elafin/trappin-2 in HIV-resistant women were confirmed using ELISA. The prospective association of elevated cervicovaginal elafin/trappin-2 levels with protection from HIV acquisition was then confirmed in an independent cohort of high-risk female sex workers.\Question: Does elevated elafin/trappin-2 in the female genital tract is associate with protection against HIV acquisition?
[EX A]: Using a unique proteomics approach in a large scale, cross-sectional cohort study, we identified elafin/trappin-2 as a novel innate immune factor, which is highly associated with resistance. This association was confirmed within an independent, prospective cohort study. Genital tract elafin/trappin-2 levels constitute a natural correlate of HIV protection in humans.

[EX Q]: Context: The purpose of this study was to examine risk of nursing home (NH) placement among older adults receiving publicly funded home and community-based services (HCBS) or assisted living (AL) and to explore whether these settings of care modify the relationship between dementia and risk of NH placement.', 'The sample consisted of dually eligible Medicare and Medicaid beneficiaries age 65 and older who received HCBS (n = 1630) or resided in AL (n = 836) in Florida between July 1999 and June 2000. Cox proportional hazards regression was used to estimate risk of NH placement over a 5-year study period and to test the interaction of setting of care by dementia status.', 'In all, 15% of HCBS participants were placed in a NH compared to 26% of AL participants. As indicated by a significant interaction term in the regression model, setting of care modified the relationship between dementia and NH placement (HR = 0.45, CI = 0.31-0.66). In post hoc analyses stratified by setting of care, dementia was associated with a 50% increased risk of NH placement from HCBS (HR = 1.50, CI = 1.12-2.02) but was not associated with placement from AL (HR = 0.86, CI = 0.63-1.16).\Question: Does setting of care modify risk of nursing home placement for older adults with dementia?
[EX A]:
The findings suggest that differences in care provided in HCBS and AL may influence subsequent NH placement for older adults with dementia.
