Curating the Palaeolithic

This guidance explains the importance of the English Palaeolithic record (about 1 million to 11,700 years ago) in its Pleistocene context and best practices for protecting it through the planning process, illustrated by case studies from across the country. The guidance focuses on the curation of the Palaeolithic and Pleistocene records (Part A) and is particularly intended for curators. It also provides background information on the Palaeolithic and Pleistocene records for those less familiar with the period (Part B). The guidance document is accompanied by a number of concise online case studies that illustrate a range of approaches for curating the Palaeolithic record. The document is intended to be used alongside other key guidance produced by Historic England, and acknowledges the primacy of relevant legislation. It is not a statement of Government policy, nor does it seek to prescribe a single methodology

Compliance with Australian stroke guideline recommendations for outdoor mobility and transport training by post-inpatient rehabilitation services: an observational cohort study

Background: Community participation is often restricted after stroke, due to reduced confidence and outdoor mobility. Australian clinical guidelines recommend that specific evidence-based interventions be delivered to target these restrictions, such as multiple escorted outdoor journeys. The aim of this study was to describe post-inpatient outdoor mobility and transport training delivered to stroke survivors in New South Wales, Australia and whether therapy differed according to type, sector or location of service provider. Methods: Using an observational retrospective cohort study design, 24 rehabilitation service providers were audited. Provider types included outpatient (n = 8), day therapy (n = 9), home-based rehabilitation (n = 5) and transitional aged care services (TAC, n = 2). Records of 15 stroke survivors who had received post-hospital rehabilitation were audited per service, for wait time, duration, amount of therapy and outdoor-related therapy. Results: A total of 311 records were audited. Median wait time for post-hospital therapy was 13 days (IQR, 5–35). Median duration of therapy was 68 days (IQR, 35–109), consisting of 11 sessions (IQR 4–19). Overall, a median of one session (IQR 0–3) was conducted outdoors per person. Outdoor-related therapy was similar across service providers,except that TAC delivered an average of 5.4 more outdoor-related sessions (95 % CI 4.4 to 6.4), and 3.5 more outings into public streets (95 % CI 2.8 to 4.3) per person, compared to outpatient services. Conclusion: The majority of service providers in the sample delivered little evidence-based outdoor mobility and travel training per stroke participant, as recommended in national stroke guidelines

Structural Conservation Despite Huge Sequence Diversity Allows EPCR Binding by the PfEMP1 Family Implicated in Severe Childhood Malaria

SummaryThe PfEMP1 family of surface proteins is central for Plasmodium falciparum virulence and must retain the ability to bind to host receptors while also diversifying to aid immune evasion. The interaction between CIDRα1 domains of PfEMP1 and endothelial protein C receptor (EPCR) is associated with severe childhood malaria. We combine crystal structures of CIDRα1:EPCR complexes with analysis of 885 CIDRα1 sequences, showing that the EPCR-binding surfaces of CIDRα1 domains are conserved in shape and bonding potential, despite dramatic sequence diversity. Additionally, these domains mimic features of the natural EPCR ligand and can block this ligand interaction. Using peptides corresponding to the EPCR-binding region, antibodies can be purified from individuals in malaria-endemic regions that block EPCR binding of diverse CIDRα1 variants. This highlights the extent to which such a surface protein family can diversify while maintaining ligand-binding capacity and identifies features that should be mimicked in immunogens to prevent EPCR binding

Quantifying the Association between Bovine and Human Trypanosomiasis in Newly Affected Sleeping Sickness Areas of Uganda

BACKGROUND: Uganda has active foci of both chronic and acute HAT with the acute zoonotic form of disease classically considered to be restricted to southeast Uganda, while the focus of the chronic form of HAT was confined to the northwest of the country. Acute HAT has however been migrating from its traditional disease focus, spreading rapidly to new districts, a spread linked to movement of infected cattle following restocking. Cattle act as long-term reservoirs of human infective T. b. rhodesiense showing few signs of morbidity, yet posing a significant risk to human health. It is important to understand the relationship between infected cattle and infected individuals so that an appropriate response can be made to the risk posed to the community from animals infected with human pathogens in a village setting. METHODOLOGY/PRINCIPAL FINDINGS: This paper examines the relationship between human T. b. rhodesiense infection and human infective and non-human T. brucei s.l. circulating in cattle at village level in Kaberamaido and Dokolo Districts, Uganda. The study was undertaken in villages that had reported a case of sleeping sickness in the six months prior to sample collection and those villages that had never reported a case of sleeping sickness. CONCLUSIONS AND SIGNIFICANCE: The sleeping sickness status of the villages had a significant effect with higher odds of infection in cattle from case than from non-case villages for T. brucei s.l. (OR: 2.94, 95%CI: 1.38-6.24). Cattle age had a significant effect (p<0.001) on the likelihood of T. brucei s.l. infection within cattle: cattle between 18-36 months (OR: 3.51, 95%CI: 1.63-7.51) and cattle over 36 months (OR: 4.20, 95%CI: 2.08-8.67) had significantly higher odds of T. brucei s. l. infection than cattle under 18 months of age. Furthermore, village human sleeping sickness status had a significant effect (p<0.05) on the detection of T. b. rhodesiense in the village cattle herd, with significantly higher likelihood of T. b. rhodesiense in the village cattle of case villages (OR: 25, 95%CI: 1.2-520.71). Overall a higher than average T. brucei s.l. prevalence (>16.3%) in a village herd over was associated with significantly higher likelihood of T. b. rhodesiense being detected in a herd (OR: 25, 95%CI: 1.2-520.71)

Drying colloidal systems: laboratory models for a wide range of applications

The drying of complex fluids provides a powerful insight into phenomena that take place on time and length scales not normally accessible. An important feature of complex fluids, colloidal dispersions and polymer solutions is their high sensitivity to weak external actions. Thus, the drying of complex fluids involves a large number of physical and chemical processes. The scope of this review is the capacity to tune such systems to reproduce and explore specific properties in a physics laboratory. A wide variety of systems are presented, ranging from functional coatings, food science, cosmetology, medical diagnostics and forensics to geophysics and art

ASSESSMENT OF VANCOMYCIN CONCENTRATIONS IN SYRINGES PREPARED WITHIN A WARD SETTING

AimVancomycin is used as a second line antibiotic in the treatment of late onset neonatal infection for its activity against coagulase negative staphylococci. Vancomycin infusions are prepared within a ward setting for administration to neonates. Differences in preparation techniques on the ward have previously been recognised as a potential source of variation in vancomycin concentrations, as compared to concentrations in pre-made preparations. This study analyses a consecutive series of vancomycin syringes prepared in a ward for administration to neonates, to determine how accurate the concentration of each preparation was compared to the expected concentration.MethodVancomycin concentrations were determined by UV analysis (λ=280 nm) with a UV spectrophotometer (Jenway Genova Plus). A calibration curve for vancomycin was created (R2=0.9996) by manufacturing a series of solutions of vancomycin hydrochloride in glucose 5% w/v.Samples of vancomycin from syringes from which doses were administered to neonates were then analysed to assess their concentration. For each syringe, mean vancomycin concentration±standard deviation was calculated (n=3).Reasonable errors in preparations were calculated based on errors in each step of the preparation process. Theoretical error was calculated based on apparatus used, and experimental error was recorded based on a simulated process. Two preparation methods were compared; the method complying with that described in the local formulary, 1 and an alternative method reported by the nurses preparing the dose.ResultsAnalysis of results showed that concentration of the vancomycin syringes prepared ranged from 0.85 to 8.24 mg/mL. The expected concentration was 4.17 mg/ml.Theoretical error in preparation of vancomycin doses was lower with the formulary-compliant method1 versus an alternative method, as were variations in in vancomycin concentration.Depending on the type of error (theoretical or experimental) and method by which vancomycin syringes were prepared (formulary1 or alternative method), the percentage of syringes with vancomycin concentration outside of the specified ranges varied from 20%–43%. This is higher compared to the findings of the Department of Health2, where it was found that 19.2% of morphine infusions prepared by nurses in the neonatal intensive care unit were outside British Pharmacopoeia concentration limits.ConclusionPreparation of vancomycin doses should follow the formulary method1 to minimise variation in concentration of the final product. Alternatively, pre-made syringes may be preferred as an alternative to ward-made syringes as this removes individualised preparation as a source of error.</jats:sec
