Background: Cystic fibrosis (CF) is a rare genetic disease affecting approximately 30,000 people in the United States (US). African American persons with CF are even rarer, comprising approximately 5% of this population. Purpose: The purpose of this study was to explore the lived experiences of African American persons with CF to identify potential disparities in health care. Methods: Descriptive phenomenology was used to explore lived experiences of African American persons with CF over age 18 recruited from CF Foundation-accredited Centers in the US, CF-specific social media, and via snowball sampling. Study data was obtained through telephone interviews that were audio-recorded, transcribed verbatim, and analyzed using Colaizzi's method of thematic analysis. Results: Six men and six women (ages 23–45) completed the study. Interviews revealed three themes: (1) Accepting a Diagnosis of CF; (2) Desiring a Normal Life while Living with an Invisible Disease; and 3) A Slippery Slope of Subtle Racism. Each theme had 2–3 subthemes. Conclusions: It is critical to explore the unique challenges faced by African American persons with CF in order to develop interventions that improve their daily lives and create better futures. Implications for Practice: Findings highlight the unique challenges faced by underrepresented groups with CF and the need to address health inequities to improve care delivery.

Objective The aim of the study is to examine the impact of maternal interpregnancy body mass index (BMI) change on subsequent offspring mortality risk. Study Design This is a retrospective cohort study of women who had two consecutive live singleton deliveries of at least 20 weeks' gestation from the Utah Population Database. Our exposure was defined as interpregnancy BMI change from the date of first delivery to the conception date of subsequent pregnancy. We categorized BMI change as: < − 1, −1 to 0, 0 to <1 (reference), 1 to 2, 2 to 4, ≥4 kg/m 2. Our primary outcome was all-cause age-specific mortality during four time periods: neonatal (≤28 days), infant (29 days to <1 year old), childhood ((≥1 to <5 years old), and late childhood (5 to <18 years old). We also examined mortality specifically attributed to congenital anomalies. Analyses used Cox proportional hazard models stratified by full term (≥37 weeks) and preterm (<37 weeks) deliveries. All models were adjusted for relevant confounders. Results Of 266,752 women, among full-term deliveries, women with a BMI increase of 4 kg/m 2 or more had an increased risk of neonatal mortality in their subsequent pregnancy (hazard ratio or HR = 1.72, 95% confidence interval or CI: 1.23–2.41) Women who lost 1 kg/m 2 or more between deliveries also had increased neonatal mortality (HR = 1.46, 95% CI: 1.04–2.05). There were no differences in infant, early, or late childhood mortality by interpregnancy BMI change. Maternal interpregnancy interval weight loss of 1 kg/m 2 or more and weight gain of ≥4 kg/m 2 also had increased risk of mortality associated with congenital anomalies or conditions arising during the neonatal period following their subsequent delivery. Conclusion Women with significant interpregnancy weight gain and modest weight loss have a significant increased risk of neonatal mortality following their subsequent pregnancy. Key Points Significant weight gain between deliveries increases the risk of neonatal death. Modest weight loss between deliveries increases the risk of neonatal death. This risk may be partially explained by increased risk of congenital malformations. [ABSTRACT FROM AUTHOR]

Hydrocephalus is a neurological disorder with an incidence of 80-125 per 100,000 live births in the United States. The molecular pathogenesis of this multidimensional disorder is complex and has both genetic and environmental influences. This review aims to discuss the genetic and molecular alterations described in human hydrocephalus, from well-characterized, heritable forms of hydrocephalus (e.g., X-linked hydrocephalus from L1CAM variants) to those affecting cilia motility and other complex pathologies such as neural tube defects and Dandy-Walker syndrome. Ventricular zone disruption is one key pattern among congenital and acquired forms of hydrocephalus, with abnormalities in cadherins, which mediate neuroepithelium/ependymal cell junctions and contribute to the pathogenesis and severity of the disease. Given the relationship between hydrocephalus pathogenesis and neurodevelopment, future research should elucidate the genetic and molecular mechanisms that regulate ventricular zone integrity and stem cell biology.

Introduction: Capturing the patient experience of living with a rare disease such as X-linked hypophosphataemia (XLH) is critical for a holistic understanding of the burden of a disease. The complexity of the disease coupled with the limited population makes elicitation of the patient burden methodologically challenging. This study used qualitative information direct from patient and caregiver statements to assess the burden of XLH.Methods: A thematic analysis was conducted on statements received during a National Institute for Health and Care Excellence (NICE) online public open consultation from 15 June to 6 July 2018. Researchers and clinical experts generated themes and codes based on expected aspects of XLH burden. Statements were independently coded by two reviewers, adding additional codes as required, and analysed by frequency and co-reporting across age groups.Results: The majority of responses were submitted from UK-based patients with some from the USA and Australia, and the statements related to children, adolescents and adults. The findings suggest that the greatest burden experienced by children is associated with conventional therapy, co-reported with dosing regimen, adherence, distress and pain. During adolescence, the burden becomes increasingly complex and multi-factorial, with an increasing psychological burden. In adults, conventional therapy co-reported with bone deformity and orthopaedic surgery, as well as pain, mobility, fatigue and dental problems, featured highly.Discussion: Whilst our study was opportunistic in nature, it has highlighted the clear and distinctive evolution of the burden of XLH, transitioning from being therapy-oriented in childhood to multi-factorial in adolescence, and finally to adulthood with its high impact on need for other interventions, function and mobility. This qualitative thematic analysis enhances the understanding of the symptom and treatment burden of XLH. [ABSTRACT FROM AUTHOR]
