Primary versus Staged Closure of Exomphalos Major: Cardiac Anomalies Do Not Affect Outcome

Aim: The objective of the study is to describe management of exomphalos major and investigate the effect of congenital cardiac anomalies. / Methods: A single-center retrospective review (with audit approval) was performed of neonates with exomphalos major (fascial defect ≥ 5cm ± liver herniation) between 2004 and 2014. Demographic and operative data were collected and outcomes compared between infants who had primary or staged closure. Data, median (range), were analyzed appropriately. Results: A total of 22 patients were included, 20 with liver herniation and 1 with pentalogy of Cantrell. Gestational age was 38 (30–40) weeks, birth weight 2.7 (1.4–4.6) kg, and 13 (60%) were male. Two were managed conservatively due to severe comorbidities, 5 underwent primary closure, and 15 had application of Prolene (Ethicon Inc) mesh silo and serial reduction. Five died, including two managed conservatively, none primarily of the exomphalos. Survivors were followed up for 38 months (2–71). Cardiac anomalies were present in 20 (91%) patients: 8 had minor and 12 major anomalies. Twelve (55%) patients had other anomalies. Primary closure was associated with shorter length of stay (13 vs. 85 days, p = 0.02), but infants had similar lengths of intensive care stay, duration of parenteral feeds, and time to full feeds. Infants with cardiac anomalies had shorter times to full closure (28 vs. 62 days, p = 0.03), but other outcomes were similar. / Conclusion: Infants whose defect can be closed primarily have a shorter length of stay, but other outcomes are similar. Infants with more significant abdominovisceral disproportion are managed with staged closure; the presence of major cardiac anomalies does not affect surgical outcome

Resolution requirements for numerical simulations of transition

The resolution requirements for direct numerical simulations of transition to turbulence are investigated. A reliable resolution criterion is determined from the results of several detailed simulations of channel and boundary-layer transition

Sustainable rural development in England: Policy problems and equity consequences

Spatial planning policies ensure a 'no development' ethic for rural areas in England, brought about by strong restrictive housing polices and an urban-centric view of sustainable development. Such an ethic is unlikely to be ameliorated by the Localism Bill passing through the English Parliament in 2010-11. Economic development policies provide confusing signals for rural sustainable development as they appear simultaneously to require the pursuit of productivity, well-being, endogenous development and income support: objectives that are not compatible. Together these policy sets are likely to exacerbate inequalities in both wealth and opportunity in rural areas. This inhibits the achievement of sustainable development when viewed as having equity considerations at its core. © The Author(s) 2012

Solution structure of a repeated unit of the ABA-1 nematode polyprotein allergen of ascaris reveals a novel fold and two discrete lipid-binding sites

Parasitic nematode worms cause serious health problems in humans and other animals. They can induce allergic-type immune responses, which can be harmful but may at the same time protect against the infections. Allergens are proteins that trigger allergic reactions and these parasites produce a type that is confined to nematodes, the nematode polyprotein allergens (NPAs). These are synthesized as large precursor proteins comprising repeating units of similar amino acid sequence that are subsequently cleaved into multiple copies of the allergen protein. NPAs bind small lipids such as fatty acids and retinol (Vitamin A) and probably transport these sensitive and insoluble compounds between the tissues of the worms. Nematodes cannot synthesize these lipids, so NPAs may also be crucial for extracting nutrients from their hosts. They may also be involved in altering immune responses by controlling the lipids by which the immune and inflammatory cells communicate. We describe the molecular structure of one unit of an NPA, the well-known ABA-1 allergen of Ascaris and find its structure to be of a type not previously found for lipid-binding proteins, and we describe the unusual sites where lipids bind within this structur

An Amish founder variant consolidates disruption of CEP55 as a cause of hydranencephaly and renal dysplasia

This is the author accepted manuscript. The final version is available from Springer Nature via the DOI in this record.The centrosomal protein 55 kDa (CEP55 (OMIM 610000)) plays a fundamental role in cell cycle regulation and cytokinesis. However, the precise role of CEP55 in human embryonic growth and development is yet to be fully defined. Here we identified a novel homozygous founder frameshift variant in CEP55, present at low frequency in the Amish community, in two siblings presenting with a lethal foetal disorder. The features of the condition are reminiscent of a Meckel-like syndrome comprising of Potter sequence, hydranencephaly, and cystic dysplastic kidneys. These findings, considered alongside two recent studies of single families reporting loss of function candidate variants in CEP55, confirm disruption of CEP55 function as a cause of this clinical spectrum and enable us to delineate the cardinal clinical features of this disorder, providing important new insights into early human development.Medical Research CouncilNewlife Foundation for disabled childre

‘It used to be brutal, now it’s an art’:changing negotiations of violence and masculinity in British karate

In most western (and indeed eastern) cultures, fighting is seen as an ultimate symbol of masculinity – an embodied display of dominance, control and violence (Bourdieu, 2001). As a space legitimising and praising performances of mimetic violence (Dunning, 1999), combat sports provide an arena where the virtues of dominance and power at the heart of conceptions of orthodox masculinity (Anderson, 2010 ) or hegemonic masculinity (Connell, 2005) can be symbolically presented by men through bodily displays of strength, physical aggression, and the taking and overcoming of pain (Bourdieu, 2001; Messner, 1990; Wacquant, 2004). Yet, over the last twenty years the focus of karate in Britain has been perceived to shift from aggressive acts of 'hitting hard' to developing and displaying controlled, acrobatic and technically precise movements. Drawn from a nine-month ethnography and 7 semi-structured interviews, this chapter explores how British male karate practitioners re/negotiate ideas of masculinity and embodiments of a masculine identity in the context of karate’s changing emphasis on, and practices of, 'violence'. This paper suggests that a 'civilising' shift (Elias and Dunning, 1986) in the competition rules increases in women’s participation in karate with men, and subsequent negotiations of mimetic violence, complicate the use of violence as a symbol of praised masculine identity within British karate . A praised masculine identity is crafted by carefully blending traits conventional deemed feminine such as technical precision, elegance and agility alongside displays of strength and dominance. Such performances challenge conceptions of an orthodox sporting masculinity and notions of hierarchical gender distinction

Short-term beneficial effects of methylene blue on kidney damage in septic shock patients

Contains fulltext : 71022.pdf (publisher's version ) (Closed access)OBJECTIVE: We previously demonstrated that upregulation of renal inducible nitric oxide synthase (iNOS) is associated with proximal tubule injury during systemic inflammation in humans. In this study we investigated the short-term effect of methylene blue (MB), an inhibitor of the NO pathway, on kidney damage and function in septic shock patients. DESIGN AND SETTING: A prospective clinical study conducted in an intensive care unit. PATIENTS: Nine patients (four men, five women, mean age 71 +/- 3 years) with confirmed or suspected bacterial infection and with refractory septic shock defined as a mean arterial pressure or = 0.2 microg/kg per minute. INTERVENTIONS: A 4 h continuous intravenous infusion of 1 mg/kg MB per hour. MEASUREMENTS AND RESULTS: The urinary excretion of NO metabolites decreased with median 90% (range 75-95%) from baseline to 6 h after MB administration. The first 24 h creatinine clearance improved by 51% (18-173%) after MB treatment but was still strongly impaired. During the first 6 h after the start of MB treatment both the urinary excretion of cytosolic glutathione S-transferase A1-1 and P1-1, markers for proximal and distal tubule damage, respectively, decreased by 45% (10-70%) and 70% (40-85) vs. baseline. After termination of the MB infusion the NO metabolites and markers of tubular injury returned to pretreatment levels. CONCLUSIONS: In septic patients with refractory shock short-term infusion of MB is associated with a decrease in NO production and an attenuation of the urinary excretion of renal tubular injury markers

Search for rare quark-annihilation decays, B --> Ds(*) Phi

We report on searches for B- --> Ds- Phi and B- --> Ds*- Phi. In the context of the Standard Model, these decays are expected to be highly suppressed since they proceed through annihilation of the b and u-bar quarks in the B- meson. Our results are based on 234 million Upsilon(4S) --> B Bbar decays collected with the BABAR detector at SLAC. We find no evidence for these decays, and we set Bayesian 90% confidence level upper limits on the branching fractions BF(B- --> Ds- Phi) Ds*- Phi)<1.2x10^(-5). These results are consistent with Standard Model expectations.Comment: 8 pages, 3 postscript figues, submitted to Phys. Rev. D (Rapid Communications

Health Journalism Internships: A Social Marketing Strategy to Address Health Disparities

The USA seeks to eliminate health disparities by stimulating the rapid uptake of health-promoting behaviors within disadvantaged communities. A health journalism internship incorporates social marketing strategies to increase communities' access to cancer information, while helping the interns who are recruited from underrepresented communities gain admission to top graduate schools. Interns are taught basic health journalism skills that enable them to create immediate streams of cancer-related press releases for submission to community newspapers. Interns are charged with the social responsibility of continuing this dissemination process throughout their careers. Intermediate outcomes are measured as mediators of distal behavioral change goals
