'Don't let it hold you back' - The experience of transition to adulthood in young people with primary ciliary dyskinesia: An interpretative phenomenological analysis.

Primary ciliary dyskinesia (PCD) is a rare, chronic genetic condition with variable features arising from motile cilia dysfunction, including recurrent respiratory infections, sinonasal disease, reduced hearing, infertility and situs inversus. The aim of the study was to understand the experiences of young people with PCD as they transition into adulthood and adult healthcare services. An interpretative phenomenological analytical method was applied. Semi-structured interviews were conducted with three participants aged 18-24 years. Four interconnected group experiential themes were identified: (1) reconceptualising a stigmatised identity, (2) sharing the journey to independence, (3) entering adulthood with newfound autonomy, (4) anticipating an uncertain future. Overall, we found that transition for young people with PCD presents as a complex period marked by identity-formation, creating systems of support and becoming an autonomous adult. Facilitation of personalised and integrated approaches to care should be prioritised. Our findings are important to help health professionals provide appropriate, anticipatory support.

Neonatal blood pressure by birth weight, gestational age, and postnatal age: a systematic review.

BACKGROUND: Blood pressure is a vital hemodynamic marker during the neonatal period. However, normative values are often derived from small observational studies. Understanding the normative range would help to identify ideal thresholds for intervention to treat hypotension or hypertension. Therefore, the aim of this study was to assess observed blood pressure values in neonates who have not received any blood-pressure modifying treatments from birth to three months postnatal age and whether these vary according to birth weight, gestational age and postnatal age. METHODS: This was a systematic review. A literature search was conducted in MEDLINE, PubMed, Embase, Cochrane Library, and CINAHL from 1946 to 2017 on blood pressure in neonates from birth to 3 months of age (PROSPERO ID CRD42018092886). Unpublished data were included where appropriate. RESULTS: Of 3,587 non-duplicate publications identified, 30 were included (one unpublished study). Twelve studies contained data grouped by birth weight, while 23 contained data grouped by gestational age. Study and clinical heterogeneity precluded meta-analyses thus results are presented by subgroup. A consistent blood pressure rise was associated with increasing birth weight, gestational age, and postnatal age. In addition, blood pressure seemed to rise more rapidly in the most preterm and low birth weight neonates. CONCLUSION: Despite blood pressure increasing with birth weight, gestational age, and postnatal age, there was marked blood pressure variability observed throughout. To better define hypotension and hypertension, future studies should develop consistent approaches for factors related to blood pressure variability, including the method and timing of measurement as well as statistical control of relevant patient characteristics.

The annotation of GBA1 has been concealed by its protein-coding pseudogene GBAP1.

Mutations in GBA1 cause Gaucher disease and are the most important genetic risk factor for Parkinson's disease. However, analysis of transcription at this locus is complicated by its highly homologous pseudogene, GBAP1. We show that >50% of short RNA-sequencing reads mapping to GBA1 also map to GBAP1. Thus, we used long-read RNA sequencing in the human brain, which allowed us to accurately quantify expression from both GBA1 and GBAP1. We discovered significant differences in expression compared to short-read data and identify currently unannotated transcripts of both GBA1 and GBAP1. These included protein-coding transcripts from both genes that were translated in human brain, but without the known lysosomal function-yet accounting for almost a third of transcription. Analyzing brain-specific cell types using long-read and single-nucleus RNA sequencing revealed region-specific variations in transcript expression. Overall, these findings suggest nonlysosomal roles for GBA1 and GBAP1 with implications for our understanding of the role of GBA1 in health and disease.

Dark Skin Representation in Mobile Applications for Dermatology Education: A Scoping Review.

There is increasing recognition regarding the need to represent ethnic diversity within dermatology education. Past evaluation of dermatology textbooks has demonstrated that depiction of dark skin makes up to 4.5%-19.9% of total photographs. The present study reviewed the representation of dark skin photography and diseases in dermatologic educational resources provided through mobile application technology. Of the 518 mobile applications reviewed, 18 were included in this analysis. A total of 6,645 in-app photographs were categorized in Fitzpatrick skin types I-IV (5,975 photographs, 89.9%), Fitzpatrick skin types V and VI (459 photographs, 6.9%), or uncertain (211 photographs, 3.2%). The degree of photographs depicting Fitzpatrick skin types V and VI ranged from 0.0% to 17.7% between different mobile applications. This was significantly different from past results derived from photographic depictions in dermatology textbooks-suggestive of fewer depictions within applications (P < 0.001). In addition, the number of mobile applications presenting educational information regarding four conditions that affect people with darker skin tones varied considerably: central centrifugal cicatricial alopecia (3 applications, 16.7%), melasma (9 applications, 50.0%), acral lentiginous melanoma (8 applications, 44.4%), and keloid scarring (11 applications, 61.1%). Overall, there is a limited depiction of darker skin tones and conditions that affect those with darker skin tones within educational mobile applications aimed at students and professionals in dermatology.

Variations in Cardiovascular Structure, Function, and Geometry in Midlife Associated With a History of Hypertensive Pregnancy.

Hypertensive pregnancy is associated with increased maternal cardiovascular risk in later life. A range of cardiovascular adaptations after pregnancy have been reported to partly explain this risk. We used multimodality imaging to identify whether, by midlife, any pregnancy-associated phenotypes were still identifiable and to what extent they could be explained by blood pressure. Participants were identified by review of hospital maternity records 5 to 10 years after pregnancy and invited to a single visit for detailed cardiovascular imaging phenotyping. One hundred seventy-three women (age, 42±5 years, 70 after normotensive and 103 after hypertensive pregnancy) underwent magnetic resonance imaging of the heart and aorta, echocardiography, and vascular assessment, including capillaroscopy. Women with a history of hypertensive pregnancy had a distinct cardiac geometry with higher left ventricular mass index (49.9±7.1 versus 46.0±6.5 g/m2; P=0.001) and ejection fraction (65.6±5.4% versus 63.7±4.3%; P=0.03) but lower global longitudinal strain (-18.31±4.46% versus -19.94±3.59%; P=0.02). Left atrial volume index was also increased (40.4±9.2 versus 37.3±7.3 mL/m2; P=0.03) and E:A reduced (1.34±0.35 versus 1.52±0.45; P=0.003). Aortic compliance (0.240±0.053 versus 0.258±0.063; P=0.046) and functional capillary density (105.4±23.0 versus 115.2±20.9 capillaries/mm2; P=0.01) were reduced. Only differences in functional capillary density, left ventricular mass, and atrial volume indices remained after adjustment for blood pressure (P<0.01, P=0.01, and P=0.04, respectively). Differences in cardiac structure and geometry, as well as microvascular rarefaction, are evident in midlife after a hypertensive pregnancy, independent of blood pressure. To what extent these phenotypic patterns contribute to cardiovascular disease progression or provide additional measures to improve risk stratification requires further study.
