Endothelial dysfunction in a child with Pearson marrow-pancreas syndrome managed with Descemet stripping automated endothelial keratoplasty using a suture pull-through techniqu

A 4-year-old girl with a history of Pearson marrow-pancreas syndrome presenting with severe, progressive photophobia was found to have bilateral, diffuse corneal thickening and peripheral pigmentary retinopathy. She underwent Descemet stripping automated endothelial keratoplasty (DSAEK) surgery in both eyes using a modified suture pull-through technique. Postoperatively there was no evidence of cataract formation or graft detachment; her corneas thinned, and her photophobia improved dramatically

Associations of actigraphy‐assessed sleep variables with adiposity and serum cardiometabolic outcomes in emerging adults

SummaryThis study assessed associations of actigraphy‐assessed sleep with adiposity and serum cardiometabolic outcomes in emerging adults, and whether sex and race modified these associations. Data on 147 emerging adults (age = 19.4 ± 1.3 years; body mass index = 26.4 ± 7.0 kg m$^{−2}$; 59% female; 65% White) from RIGHT Track Health were used. Actigraphy‐based sleep measures included sleep duration, sleep efficiency, sleep timing midpoint, day‐to‐day sleep duration and sleep timing midpoint variability. Combined sleep duration and sleep timing behaviours were also derived (early‐bed/late‐rise, early‐bed/early‐rise, late‐bed/late‐rise, late‐bed/early‐rise). Outcomes included body mass index and BodPod‐assessed fat mass index, fasting serum leptin, C‐reactive protein, and homeostatic model assessment‐insulin resistance. Sleep duration was 5.4 h per night. We noted an inverse association between sleep duration and homeostatic model assessment‐insulin resistance. The early‐bed/early‐rise group had greater body mass index, C‐reactive protein and homeostatic model assessment‐insulin resistance compared with the early‐bed/late‐rise group (referent). Sex modified associations of sleep efficiency with C‐reactive protein; stratified results revealed positive association between sleep efficiency and C‐reactive protein in males, but not females. Race modified associations of sleep duration with body mass index and leptin, and of sleep duration variability with C‐reactive protein. Stratified analyses revealed inverse associations between sleep duration with body mass index and leptin in Black, multiracial/other race individuals only. Positive association between sleep duration variability and C‐reactive protein was noted in White individuals only. Shorter sleep duration, particularly when combined with earlier sleep timing, is associated with greater adiposity and serum cardiometabolic outcomes. Additional studies are needed to assess individual‐ and contextual‐level factors that may contribute to sex and race differences in sleep health and cardiometabolic risk in emerging adults

Vitamin D status is heritable and under environment‐dependent selection in the wild

Vitamin D has a well‐established role in skeletal health and is increasingly linked to chronic disease and mortality in humans and companion animals. Despite the clear significance of vitamin D for health and obvious implications for fitness under natural conditions, no longitudinal study has tested whether the circulating concentration of vitamin D is under natural selection in the wild. Here, we show that concentrations of dietary‐derived vitamin D(2) and endogenously produced vitamin D(3) metabolites are heritable and largely polygenic in a wild population of Soay sheep (Ovis aries). Vitamin D(2) status was positively associated with female adult survival, and vitamin D(3) status predicted female fecundity in particular, good environment years when sheep density and competition for resources was low. Our study provides evidence that vitamin D status has the potential to respond to selection, and also provides new insights into how vitamin D metabolism is associated with fitness in the wild

Enterohepatic Helicobacter in ulcerative colitis:Potential pathogenic entities?

Background: Changes in bacterial populations termed "dysbiosis" are thought central to ulcerative colitis (UC) pathogenesis. In particular, the possibility that novel Helicobacter organisms play a role in human UC has been debated but not comprehensively investigated. The aim of this study was to develop a molecular approach to investigate the presence of Helicobacter organisms in adults with and without UC.Methodology/Principal Findings: A dual molecular approach to detect Helicobacter was developed. Oligonucleotide probes against the genus Helicobacter were designed and optimised alongside a validation of published H. pylori probes. A comprehensive evaluation of Helicobacter genus and H. pylori PCR primers was also undertaken. The combined approach was then assessed in a range of gastrointestinal samples prior to assessment of a UC cohort. Archival colonic samples were available from 106 individuals for FISH analysis (57 with UC and 49 non-IBD controls). A further 118 individuals were collected prospectively for dual FISH and PCR analysis (86 UC and 32 non-IBD controls). An additional 27 non-IBD controls were available for PCR analysis. All Helicobacter PCR-positive samples were sequenced. The association between Helicobacter and each study group was statistically analysed using the Pearson Chi Squared 2 tailed test. Helicobacter genus PCR positivity was significantly higher in UC than controls (32 of 77 versus 11 of 59, p = 0.004). Sequence analysis indicated enterohepatic Helicobacter species prevalence was significantly higher in the UC group compared to the control group (30 of 77 versus 2 of 59, p&lt;0.0001). PCR and FISH results were concordant in 74 (67.9%) of subjects. The majority of discordant results were attributable to a higher positivity rate with FISH than PCR.Conclusions/Significance: Helicobacter organisms warrant consideration as potential pathogenic entities in UC. Isolation of these organisms from colonic tissue is needed to enable interrogation of pathogenicity against established criteria.</p

Practice Nurse Education Needs Analysis survey results.

This report describes the outcomes from a questionnaire completed by practice nurses in the CWHHE CCG collaborative and the outer NWL CCGs. Data from the CWHHE CCGs were collected by Bucks New University. Data from the outer NWL CCGs were collected by the University of West London, using a survey based on that used by Bucks. The Aims of the study were to: • identify the key education priorities for practice nursing across the 8 NW London CCGs; • explore future practice and education requirements for practice nurses to: further service transformation to improve health outcome and patient/client experience eg to deliver ‘out of hospital care’ in line with both CCG and NW London wide strategy; ensure that practice nursing is well placed to deliver on (and where appropriate lead) service and practice development in line with local commissioning and service delivery priorities. • identify the education, training, development and support needs of the practice nurses in undertaking current and future roles and activities
