Quality of life is lower in food allergic adolescents compared to young children at a community educational symposium.

INTRODUCTION: Food allergies (FA) can detrimentally impact physical, emotional, and psychological quality of life (QoL) among pediatric patients. Given the changes from childhood into adolescence, the impact of FA on QoL likely evolves with age. The purpose of this study was to determine whether QoL differed between adolescents and children with FA who participated in a Food Allergy Symposium (FAS). METHODS: Patients with confirmed FA were recruited at an educational community symposium in September 2018 and September 2019. Patients and/or their parents were invited to complete the Food Allergy Quality of Life Questionnaires (FAQLQ). The Food Allergy Independent Measure (FAIM) reflects concerns about accidental food exposure and disease severity. Higher FAIM and FAQLQ scores reflect worse QoL. Summary scores were compared using the Wilcoxon rank sum test, Fisher's exact test, or the Chi-square test. RESULTS: Seventy-four surveys (82% children, 18% adolescents) were included. The FAQLQ total score was higher among adolescents than children (median 5.2 vs 4.2; p = 0.045), and the FAIM was lower in adolescents (median 2.2 vs 2.8; p = 0.037). More adolescents reported previous anaphylaxis than children (91.7% vs 51.8%; p = 0.011). The percentage reassured by having epinephrine was higher in adolescents (81.8% vs 45.8%; p = 0.046). No other QoL scores and survey responses were significantly different. DISCUSSION: In this study, adolescents were more concerned about their disease and more reassured by epinephrine carriage than younger children, which may reflect increased autonomy and responsibility. Community events are an important way to assess QoL and provide FA-related education to pediatric patients.

Maximum Dose Food Challenges Reveal Transient Sustained Unresponsiveness in Peanut Oral Immunotherapy (POIMD Study).

BACKGROUND: The maximum tolerated dose of peanut protein following peanut oral immunotherapy (POIT) is unknown because most research studies have not examined very high thresholds. OBJECTIVE: To define the maximum dose tolerated by patients on POIT and severity of allergic reactions after a 1-month period of treatment discontinuation. METHODS: In a phase 2 3-year POIT open-label study, we enrolled participants age 5 to 13 years with a 1-year build-up period followed by a 2-year daily maintenance dose of 3900 mg with assessment of the maximum tolerated dose using double-blind placebo-controlled food challenges (DBPCFCs) of 26,225 mg cumulative dose of peanut protein. The DBPCFC was performed at baseline, after 12-month build-up, at 2 year of maintenance, and after a 1-month period of treatment discontinuation. Biomarkers were assessed every 6 weeks for the first 6 months of therapy. A general linear mixed model was used for analysis. RESULTS: The mean maximum cumulative tolerated dose after 12 months increased by 12,063 mg (P < .001) (n = 12), slightly decreased during maintenance (n = 11), and significantly decreased by 7593 mg after avoidance for 1 month (P = .03) (n = 6). Biomarker analysis revealed decreases in cytokine expression within the first 6 weeks of initiation of POIT and decreased peanut-IgG4 and increased cytokine expression after 1 month of discontinuation. The DBPCFC reaction severity, examined through a symptom score with 1 point for each defined symptom, decreased after 12 months, but did not significantly change after 1 month of POIT discontinuation. CONCLUSIONS: The evaluation of POIT and sustained unresponsiveness by maximum tolerated dose by DBPCFCs in this small phase 2 trial showed that desensitization is diminished, with 100% loss of tolerated dose after 1 month of avoidance following 3 years of treatment.

Maternal development experiences of women hospitalized to prevent preterm birth.

OBJECTIVE: To examine ways that women's experience of hospitalization with bed rest to prevent preterm birth impacts prenatal maternal development. METHOD: Interviews based on the Interview Schedules for Dimensions of Maternal Development in Psychosocial Adaptation to Pregnancy were conducted at a hospital in the southwestern United States with a convenience sample of 41 women during confinement to bed rest to prevent preterm birth. The interviews were recorded, and verbatim transcripts were submitted to thematic analysis. RESULTS: Five themes were mapped from the women's narratives: (1) acceptance of pregnancy, but with fears specific to elevated risks to self and baby; (2) heightened identification with motherhood and fatherhood protector roles; (3) renewal or deepening of mother-daughter closeness intensified by high-risk pregnancy; (4) enhanced couple support and collaboration; and (5) acceptance of responsibility to perform in remaining pregnant and preparing for labor, but willingness to accept help from doctors and nurses. CONCLUSIONS: This study of hospitalization to prevent preterm birth showed that women experience hospitalization as a burden to be endured to meet future goals, but that it also can facilitate prenatal maternal development in psychosocial adaptation to high risk pregnancy. Implications for research and practice are discussed.

A model program: neonatal nurse practitioners providing community health care for high-risk infants.

Perinatal drug exposure costs our communities millions of dollars each year in hospital fees and in services such as foster care, child protection, and drug treatment. Infants and their families in this group require substantial long-term health care and community resources. Neonatal health care providers should take an active role in developing and implementing home visitation programs to support early hospital discharge and continuity of care for these high-risk infants and their families. Neonatal nurse practitioners should prepare in the future to practice not only in secondary-- and tertiary--level neonatal centers, but also in follow-up clinics, long-term developmental centers, and the community This article describes a home intervention program delivered by neonatal nurse practitioners for high-risk infants and their mothers. The target population is infants exposed prenatally to drugs and/or alcohol.

Effects of a low sodium diet on bone metabolism.

Osteoporosis is a serious public health problem, and dietary interventions may potentially be helpful in preventing this disorder. The purpose of this study was to determine the effects of a low sodium diet on bone metabolism in postmenopausal women. This was a longitudinal study to determine the effects of a low sodium (2-g/day) diet on bone. Forty postmenopausal African-American and Caucasian women were enrolled in a 2-g/day sodium diet for 6 months. Sodium and calcium excretion, bone turnover, and calcitropic hormones (intact parathyroid hormone (PTH) and 1,25 dihydroxyvitamin D) were measured before and 6 months after the intervention. In women who had baseline sodium excretions equal to or greater than the average sodium intake in the United States (> or =3.4 g/day), the low sodium diet resulted in significant decreases in sodium excretion (P = 0.01), in calcium excretion (P = 0.01), and in a biomarker of bone turnover, aminoterminal propeptide of type I collagen (P = 0.04). However, there were no significant changes in calcitropic hormones, including intact PTH (P = 0.97) or 1,25 dihydroxyvitamin D (P = 0.49) with the low sodium diet. These findings suggest that in postmenopausal women with sodium intakes > or =3.4 g/day, a low sodium diet may have benefits for skeletal health.
