PROBLEM: To become a parent is an emotionally life-changing experience. Paternal depression during the postnatal period has been associated with emotional and behavioral problems in children. The condition has predominantly been related to mothers, and the recognition of paternal postnatal depression (PND) has been paid less attention to. PND in fathers may be difficult to detect. However, nurses in pediatric services meet a lot of fathers and are in a position to detect a father who is suffering from PND. Therefore, the aim of this study was (a) to explore Child Health Center nurses' experiences of observing depression in fathers during the postnatal period; and (b) to explore hindrances of observing these fathers.", 'A qualitative descriptive study was conducted. Ten nurses were interviewed in 2014. A thematic data analysis was performed and data were analyzed for meaning.', 'Paternal PND was experienced as being vague and difficult to detect. Experiences of fathers with such problems were limited, and it was hard to grasp the health status of the fathers, something which was further complicated when routines were lacking or when gender attitudes influenced the daily work of the nurses.

PROBLEM: Apical potassium channels regulate ion transport in airway epithelial cells and influence air surface liquid (ASL) hydration and mucociliary clearance (MCC). We sought to identify whether genetic variation within genes encoding airway potassium channels is associated with chronic rhinosinusitis (CRS).', "Single nucleotide polymorphism (SNP) genotypes for selected potassium channels were derived from data generated on the Illumnia HumanHap550 BeadChip or Illumina Human610-Quad BeadChip for 828 unrelated individuals diagnosed with CRS and 5,083 unrelated healthy controls from the Children's Hospital of Philadelphia (CHOP). Statistical analysis was performed with set-based tests using PLINK, and corrected for multiple testing.", 'Set-based case control analysis revealed the gene KCNMA1 was associated with CRS in our Caucasian subset of the cohort (598 CRS cases and 3,489 controls; p\u200a=\u200a0.022, based on 10,000 permutations). In addition there was borderline evidence that the gene KCNQ5 (p\u200a=\u200a0.0704) was associated with the trait in our African American subset of the cohort (230 CRS cases and 1,594 controls). In addition to the top significant SNPs rs2917454 and rs6907229, imputation analysis uncovered additional genetic variants in KCNMA1 and in KCNQ5 that were associated with CRS.

PROBLEM: We aim to find what is the relationship between B cell antibody responses and specific T cell help in the specific cases of allergy and tolerance to peanuts.', 'B cell antibody responses to foreign proteins usually depend upon antigen-specific T cell help. However, specific antibody levels can sometimes be maintained lifelong after infections or vaccination.', 'We measured peanut-specific proliferation and antibody levels in peanut-allergic and non-allergic children using tritiated thymidine incorporation and UniCAP, respectively. We also investigated the corresponding tetanus toxoid specific responses in both groups.', "We found that tetanus-specific IgG did not correlate with lymphocyte proliferation (Spearman rank correlation coefficient r'=0.08, P=0.74) nor with tetanus-specific cytokine production (IFN-gamma: r'=0.198, P=0.285; TNF-alpha: r'=0.274, P=0.146; IL-4: r'=-0.007, P=0.96; P=0.221; IL-13: r'=0.363, P=0.056). Conversely, in peanut-allergic donors, peanut-specific IgE (average 21 kU/L, median 2.27 kU/L, range 0.34-100 kU/L) but not peanut-specific IgG was positively correlated with proliferation (r'=0.751, P=0.003). In these donors, specific IgE was positively correlated with peanut-specific Th2 cytokines production: r'=0.635, P=0.02 for IL-4 and r'=0.641, P=0.025 for IL-13 and negatively correlated with Th1 cytokines (r'=-0.71, P=0.007 for IFN-gamma and r'=-0.746, P=0.005 for TNF-alpha, respectively). However, peanut-specific IgE was not correlated with T cell proliferation or cytokine production in non-allergic individuals. In conclusion, in allergic individuals, B and T cell responses to peanut antigens are correlated whereas normal immune responses B and T cell responses are uncoupled.
