Abstract
BACKGROUND Type 2 diabetes in young people is an aggressive disease with a greater risk of complications leading to increased morbidity and mortality during the most productive years of life. Prevalence in the UK and globally is rising yet experience in managing this condition is limited. There are no consensus guidelines in the UK for the assessment and management of paediatric type 2 diabetes. METHODS Multidisciplinary professionals from The Association of Children's Diabetes Clinicians (ACDC) and the National Type 2 Diabetes Working Group reviewed the evidence base and made recommendations using the Grading Of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. RESULTS AND DISCUSSION Young people with type 2 diabetes should be managed within a paediatric diabetes team with close working with adult diabetes specialists, primary care and other paediatric specialties. Diagnosis of diabetes type can be challenging with many overlapping features. Diabetes antibodies may be needed to aid diagnosis. Co-morbidities and complications are frequently present at diagnosis and should be managed holistically. Lifestyle change and metformin are the mainstay of early treatment, with some needing additional basal insulin. GLP1 agonists should be used as second-line agents once early ketosis and symptoms are controlled. Glycaemic control improves microvascular but not cardiovascular risk. Reduction in excess adiposity, smoking prevention, increased physical activity and reduction of hypertension and dyslipidaemia are essential to reduce major adverse cardiovascular events. CONCLUSIONS This evidence-based guideline aims to provide a practical approach in managing this condition in the UK.

Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
Real-time continuous glucose monitoring (rtCGM) and FreeStyle Libre glucose monitoring systems (isCGM) are new evolving technologies used in the management of Type 1 diabetes. They offer potential to improve diabetes control and reduce hypoglycaemia. rtCGM can be linked to insulin pump providing hybrid closed loop therapy. Families of children and young people are keen to have the benefit from these technologies. These are relatively expensive so it is important that health care professionals, families of children and young people (CYP) with diabetes are adequately trained in the use of these devices. Health care professionals need to be able to make patient selection based on individual needs and preferences to achieve maximum benefit. Association of Children's Diabetes Clinicians (ACDC) developed a comprehensive guideline in 2017 to help identify which patients may be most likely to benefit and how these technologies may be practically implemented. Since then new technologies have been introduced and the use of GCM has expanded in routine clinical practice. This article, aims to provide a practical approach and help identify which patients may be most likely to benefit and how the technology may be implemented in order to maximise the clinical benefits.

Abstract
We have developed a dual-antigen COVID-19 vaccine incorporating genes for a modified SARS-CoV-2 spike protein (S-Fusion) and the viral nucleocapsid (N) protein with an Enhanced T-cell Stimulation Domain (N-ETSD) to increase the potential for MHC class II responses. The vaccine antigens are delivered by a human adenovirus serotype 5 platform, hAd5 [E1-, E2b-, E3-], previously demonstrated to be effective in the presence of Ad immunity. Vaccination of rhesus macaques with the hAd5 S-Fusion + N-ETSD vaccine by subcutaneous prime injection followed by two oral boosts elicited neutralizing anti-S IgG and T helper cell 1-biased T-cell responses to both S and N that protected the upper and lower respiratory tracts from high titer (1 x 106 TCID50) SARS-CoV-2 challenge. Notably, viral replication was inhibited within 24 hours of challenge in both lung and nasal passages, becoming undetectable within 7 days post-challenge.

Abstract
Liver disease represents an increasing cause of global morbidity and mortality. Currently, liver transplant is the only treatment curative for end-stage liver disease. Donor organs cannot meet the demand and therefore scalable treatments and new disease models are required to improve clinical intervention. Pluripotent stem cells represent a renewable source of human tissue. Recent advances in three-dimensional cell culture have provided the field with more complex systems that better mimic liver physiology and function. Despite these improvements, current cell-based models are variable in performance and expensive to manufacture at scale. This is due, in part, to the use of poorly defined or cross-species materials within the process, severely affecting technology translation. To address this issue, we have developed an automated and economical platform to produce liver tissue at scale for modelling disease and small molecule screening. Stem cell derived liver spheres were formed by combining hepatic progenitors with endothelial cells and stellate cells, in the ratios found within the liver. The resulting tissue permitted the study of human liver biology 'in the dish' and could be scaled for screening. In summary, we have developed an automated differentiation system that permits reliable self-assembly of human liver tissue for biomedical application. Going forward we believe that this technology will not only serve as anin vitroresource, and may have an important role to play in supporting failing liver function in humans.

Abstract
Background Hyperhidrosis is estimated to affect ~ 4.8% of the US population, and most patients experience a negative psychological impact. Here, we describe development and psychometric evaluation of a patient-reported outcome (PRO) measure to assess severity of axillary hyperhidrosis in clinical trials that meets current U.S. regulatory standards to support product approvals. Methods Three rounds of hybrid concept-elicitation/cognitive-debriefing qualitative interviews were conducted in adults with clinician-diagnosed primary axillary hyperhidrosis, followed by similar interviews in children/adolescents. The draft measure included diary items for presence, severity, impact and bothersomeness (basis of the Axillary Sweating Daily Diary [ASDD]), exploratory weekly impact items, and a single-item Patient Global Impression of Change (PGIC). Phase 2 (adults only) and phase 3 (adults and children ≥9 years) clinical trial data were utilized to evaluate measurement properties of the resulting draft measure: floor/ceiling effects, nonresponse bias, test-retest reliability, construct validity, and responsiveness were assessed. The primary concept of interest was axillary sweating severity (ASDD Item 2); however, additional supportive concepts were explored to allow for development of a comprehensive hyperhidrosis measure. Results Twenty-nine patient interviews were conducted (N = 21 adult and N = 8 children/adolescents), resulting in the ASDD (4 items, patients ≥16y) and child-specific ASDD-C (2 items ≥9y to <16y), as well as 6 Weekly Impact items and the PGIC (patients ≥16y). No floor/ceiling effects or response biases were identified. Consistency between hypothesized and observed correlation patterns between ASDD/ASDD-C items and other efficacy measures supported construct validity. Intraclass correlation coefficients supported test-retest reliability (0.91–0.93; Item 2). Large effect sizes (− 2.2 to − 2.4) demonstrated that the ASDD/ASDD-C Item 2 could detect changes in hyperhidrosis severity, supporting the measure’s responsiveness. Patients perceiving a moderate improvement in symptoms on the PGIC experienced an average 3.8-point improvement on ASDD axillary sweating severity (Item 2); thus, a 4-point responder threshold was defined as a clinically meaningful change. Conclusions Qualitative and quantitative evidence support the reliability and validity of the ASDD/ASDD-C and its use in the clinical evaluation of axillary hyperhidrosis treatments. Further evaluation of this measure in future research studies is warranted to demonstrate consistent performance across different axillary hyperhidrosis populations and in different study contexts.

Abstract
BACKGROUND Certolizumab pegol, an Fc-free, PEGylated, anti-tumour necrosis factor (TNF) biologic, has demonstrated favourable results in three ongoing, phase 3, randomized, double-blinded, placebo-controlled trials in adults with psoriasis. OBJECTIVE Data were pooled from the ongoing trials to investigate efficacy in selected subgroups and add precision to estimates of treatment effects during the initial 16 weeks of treatment. METHODS In each trial, patients ≥18 years with moderate-to-severe chronic plaque psoriasis for ≥6 months were randomized to receive certolizumab 400 mg, certolizumab 200 mg or placebo every 2 weeks for 16 weeks. Coprimary endpoints for the pooled analysis were responder rates at Week 16, defined as ≥75% reduction in psoriasis area and severity index (PASI 75) and physician global assessment (PGA) of 0/1 ('clear'/'almost clear' with ≥2-category improvement). Safety was assessed by treatment-emergent adverse events. RESULTS A total of 850 patients treated with certolizumab 400 mg (N = 342), certolizumab 200 mg (N = 351) or placebo (N = 157) were included in the pooled analysis. At Week 16, PASI 75 and PGA 0/1 responder rates were 80.1% and 63.7% in the certolizumab 400 mg group, 74.5% and 54.6% in the certolizumab 200 mg group, and 7.5% and 2.8% in the placebo group (P < 0.0001 for each dose versus placebo). In patients with and without prior biologic therapy, both doses of certolizumab resulted in substantially higher responder rates versus placebo. The incidence of adverse events was generally similar between the 400 mg and placebo groups, and somewhat lower in the 200 mg group versus placebo. No new safety signals were identified. CONCLUSION Certolizumab pegol 400 mg or 200 mg every 2 weeks for 16 weeks was associated with statistically significant and clinically meaningful improvements in signs and symptoms of psoriasis in patients with and without prior biologic therapy, and a safety profile consistent with the anti-TNF class in psoriasis.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Assessing the environmental impact of salmon farms on benthic systems is traditionally undertaken using biotic indices derived from microscopic analyses of macrobenthic infaunal (MI) communities. In this study, we tested the applicability of using foraminiferal-specific high-throughput sequencing (HTS) metabarcoding for monitoring these habitats. Sediment samples and physico-chemical data were collected along an enrichment gradient radiating out from three Chinook salmon (Oncorhynchus tshawytscha) farms in New Zealand. HTS of environmental DNA and RNA (eDNA/eRNA) resulted in 1,875,300 sequences that clustered into 349 Operational Taxonomic Units. Strong correlations were observed among various biotic indices calculated from MI data and normalized fourth-root transformed HTS data. Correlations were stronger using eRNA compared to eDNA data. Quantile regression spline analyses identified 12 key foraminiferal taxa that have potential to be used as bioindicator species. This study demonstrates the huge potential for using this method for biomonitoring of fish-farming and other marine industrial activities.

Abstract
OBJECTIVE To examine the anti-inflammatory activities of tea tree oil (TTO) in vivo. METHODS Mice were sensitized to a chemical hapten, trinitrochlorobenzene, on their ventral skin and 7 days later challenged (or re-exposed) on their dorsal skin with the same hapten. RESULTS TTO applied 30 min before or up to 7 h after to the same dorsal site as hapten challenge caused a significant reduction in skin swelling after 24 h. TTO reduced oedema but not the influx of inflammatory cells. This finding was supported by the inability of TTO to suppress TNFalpha-induced E-selectin expression by human umbilical vein endothelial cells. TTO did not suppress irritant- or ultraviolet B-induced oedema. CONCLUSION Topical TTO, specifically the TTO components, terpinen-4-ol and alpha-terpineol can regulate the oedema associated with the efferent phase of a contact hypersensitivity response.

Abstract
BACKGROUND Neonatal necrotising enterocolitis is a serious, commonly fatal disease in premature neonates. Although feeding with expressed breast milk and other good nursery practices are partly protective, preventive measures are needed. Treating neonates enterally with a mixture of human IgA and IgG, prepared from donated blood, has been claimed to protect against necrotising enterocolitis. However, no IgA preparation is available in Australia. Our aim, therefore, was to identify whether or not enteral IgG could prevent the disorder. METHODS We did a multicentre, double-blind, placebo- controlled trial. We randomly assigned 768 infants to receive human IgG 1200 mg/kg daily, and 761 to receive placebo, for up to 28 days. Treatment began at the same time as enteral feeding. The primary outcome measure was the proportion of infants who developed definite necrotising enterocolitis during the trial, and any deaths that resulted from the disorder in the treatment and placebo groups. Analysis was on an intention-to-treat basis. FINDINGS 43 infants developed definite necrotising enterocolitis in the IgG group, ten of whom died. In the placebo group, 41 infants contracted the disorder and six died (p=0.47). 25 infants on IgG and 36 on placebo had suspect necrotising enterocolitis (p=0.14). INTERPRETATION Supplementation of enteral feeds with human IgG does not reduce necrotising enterocolitis.

Abstract
The objective of this preliminary study was to evaluate more fully the role of daily spiritual experiences and daily religious/spiritual coping in the experience of individuals with pain due to rheumatoid arthritis (RA). Thirty-five individuals with RA were asked to keep a structured daily diary for 30 consecutive days. The diary included standardized measures designed to assess spiritual experiences, religious and spiritual pain coping, salience of religion in coping, religious/spiritual coping efficacy, pain, mood, and perceived social support. The participants in this study reported having spiritual experiences, such as feeling touched by the beauty of creation or feeling a desire to be closer or in union with God, on a relatively frequent basis. These participants also reported using positive religious and spiritual coping strategies much more frequently than negative religious and spiritual coping strategies. Although most of the variance in these measures was due to differences between persons, each measure also displayed a significant variability in scores from day to day. Indeed, there was just as much (or more) variability in these measures over time as there was variability in pain. Individuals who reported frequent daily spiritual experiences had higher levels of positive mood, lower levels of daily negative mood, and higher levels of each of the social support domains. Individuals who reported that religion was very salient in their coping with pain reported much higher levels of instrumental, emotional, arthritis-related, and general social support. Coping efficacy was significantly related to pain, mood, and social support in that on days that participants rated their ability to control pain and decrease pain using spiritual/religious coping methods as high, they were much less likely to have joint pain and negative mood and much more likely to have positive mood and higher levels of general social support. Taken together, these results suggest that daily spiritual experiences and daily religious/spiritual coping variables are important in understanding the experience of persons who have RA. They also suggest that newly developed daily diary methods may provide a useful methodology for studying religious and spiritual dimensions of living with arthritis.

Abstract
This Position Paper reviews the role, standards of practice, education, training and staffing requirements for radiation oncology physics. The role and standard of practice for an expert in radiation oncology physics, as defined by the ACPSEM, are consistent with the IAEA recommendations. International standards of safe practice recommend that this physics expert be authorised by a Regulatory Authority (in consultation with the professional organization). In order to accommodate the international and AHTAC recommendations or any requirements that may be set by a Regulatory Authority, the ACPSEM has defined the criteria for a physicist-in-training, a base level physicist, an advanced level physicist and an expert radiation oncology physicist. The ACPSEM shall compile separate registers for these different radiation oncology physicist categories. What constitutes a satisfactory means of establishing the number of physicists and support physics staff that is required in radiation oncology continues to be debated. The new ACPSEM workforce formula (Formula 2000) yields similar numbers to other international professional body recommendations. The ACPSEM recommends that Australian and New Zealand radiation oncology centres should aim to employ 223 and 46 radiation oncology physics staff respectively. At least 75% of this workforce should be physicists (168 in Australia and 35 in New Zealand). An additional 41 registrar physicist positions (34 in Australia and 7 in New Zealand) should be specifically created for training purposes. These registrar positions cater for the present physicist shortfall, the future expansion of radiation oncology and the expected attrition of radiation oncology physicists in the workforce. Registrar physicists shall undertake suitable tertiary education in medical physics with an organised in-house training program. The rapid advances in the theory and methodology of the new technologies for radiation oncology also require a stringent approach to maintaining a satisfactory standard of practice in radiation oncology physics. Appropriate on-going education of radiation oncology physicists as well as the educating of registrar physicists is essential. Institutional management and the ACPSEM must both play a key role in providing a means for satisfactory staff tuition on the safe and expert use of existing and new radiotherapy equipment.

Abstract
This article is a review of how a school of nursing and midwifery might promote scholarship within the university system. It is argued that the emphasis on research in universities has undermined the importance of scholarship within education and practice. The difficulties of recognizing scholarly processes as opposed to products such as publications is outlined in relation to three areas of potential scholarship within nurse education, i.e. research, teaching and practice. Issues are raised about how scholarship might be promoted in these three areas in practical terms. It is argued that systems of recognition and reward should be equitably distributed between these wide areas of potential scholarship. This will mean universities accommodating different models of scholarship and nurses recognizing their responsibility to contribute to scholarly activity.

Abstract
Apolipoprotein-E (apoE) protects against coronary artery disease via hepatic removal of atherogenic remnant lipoproteins, sequestration of cholesterol from vessel walls and local anti-oxidant, anti-platelet and anti-inflammatory actions. ApoE gene transfer may thus ameliorate a hyperlipidaemic profile and have beneficial effects at lesion sites to prevent or regress atherosclerosis, a concept endorsed by adenoviral-mediated hepatic expression studies. Here, using plasmid vectors expressing allelic human apoE2 or apoE3 isoforms, skeletal muscle was evaluated as an effective secretory platform for apoE gene augmentation. Transfected myoblasts and myotubes were found to efficiently secrete recombinant apoE in vitro as spherical 10-16 nm lipoprotein particles with pre-beta mobility. Intramuscular plasmid injection in apoE(-/-) mice, which develop spontaneous atherosclerotic plaque and xanthoma resulted in expression and secretion of apoE. Human apoE mRNA was detected by RT-PCR in injected muscles and, although concentrations of apoE3, which is rapidly cleared from plasma, were near ELISA detection limits, levels of plasma apoE2 were measurable (17.5 +/- 4.3 ng/ml). To assess whether muscle-based expression of apoE2 could inhibit atherogenesis, long-term follow-up studies were conducted. Although hyperlipidaemia was not reduced in treated animals, end-point pathology showed clear retardation of atherosclerotic and xanthomatous lesions. Up to 9 months following a single apoE2 plasmid administration, atherosclerotic lesion coverage in proximal aorta was significantly reduced by 20-30% (P < 0.01), whereas development of gross dorsal xanthoma (>5 mm diameter) was effectively reduced to zero. We conclude that expression of apoE from ectopic muscle sites has therapeutic potential to limit progression of atherosclerosis.

Abstract
Inflammation is a basic pathological mechanism that underlies many diseases. An important component of the inflammatory response is the passage of plasma components and leukocytes from the blood vessel into the tissues. The endothelial monolayer lining blood vessels reacts to stimuli such as thrombin or vascular endothelial growth factor by changes in cell-cell junctions, an increase in permeability, and the leakage of plasma components into tissues. Other stimuli, such as tumor necrosis factor-alpha (TNF-alpha), are responsible for stimulating the transmigration of leukocytes. Here we show that angiopoietin-1, a cytokine essential in fetal angiogenesis, not only supports the localization of proteins such as platelet endothelial cell adhesion molecule-1 (PECAM-1) into junctions between endothelial cells and decreases the phosphorylation of PECAM-1 and vascular endothelial cadherin, but it also strengthens these junctions, as evidenced by a decrease in basal permeability and inhibition of permeability responses to thrombin and vascular endothelial growth factor. Furthermore, angiopoietin-1 inhibits TNF-alpha-stimulated leukocyte transmigration. Angiopoietin-1 may thus have a major role in maintaining the integrity of endothelial monolayers.

Abstract
We compare methods of detection of intercellular transport of the herpes simplex virus protein VP22 and of a green fluorescent protein (GFP)-VP22 fusion protein. Spread of both proteins was observed by immunofluorescence (IF) using organic fixatives. Spread of both proteins was also detected by IF after paraformaldehyde (PFA) fixation and detergent permeabilization, albeit at reduced levels. However, while spread of GFP-VP22 was observed by examining intrinsic GFP fluorescence after methanol fixation, little spread was observed after PFA fixation, suggesting that the levels of the fusion protein in recipient cells were below the detection limits of intrinsic-fluorescence or that PFA fixation quenches the fluorescence of GFP-VP22. We further considered whether elution of VP22 from methanol-fixed cells and postfixation binding to surrounding cells contributed to the increased detection of spread observed after methanol fixation. The results show that while this could occur, it appeared to be a minor effect not accounting for the observed VP22 cell-to-cell spread in culture.

Abstract
Foot-and-mouth disease virus (FMDV) capsids are inherently labile under mildly acidic conditions, dissociating to pentamers at pH values in the region of 6.5, with the release of protein 1A and the viral RNA. This acid-induced disassembly is thought to be required for the entry of the virus genome into the host cell. Previous work has highlighted a histidine-alpha-helix charge-dipole interaction at the twofold axes of symmetry between pentamers and has suggested that this interaction plays a role in acid-induced disassembly. The validity of this theory has now been tested by converting the implicated residue, His-142 of protein 1C, to Arg, Phe and Asp. The effects of such changes were studied by using a previously described vaccinia virus expression system, in which synthesis and processing of FMDV capsid proteins results in the self-assembly of capsids. In agreement with the histidine-alpha-helix charge-dipole theory, assembly in the arginine mutant was found to be greatly reduced, while capsids of the aspartic acid mutant were considerably more stable under acidic conditions than the wild-type. Aberrant but acid-stable complexes were obtained in the phenylalanine mutant.

Abstract
Gene transfer by direct intramuscular injection of naked plasmid DNA has been shown to be a safe, simple but relatively inefficient method for gene delivery in vivo. Eukaryotic plasmid expression vectors incorporating the Epstein-Barr virus (EBV) origin of replication (oriP) and EBNA1 gene have been shown to act as autonomous episomally replicating gene transfer vectors which additionally provide nuclear matrix retention functions. Prolonged expression of a LacZ reporter gene and recombinant human dystrophin was shown using EBV-based plasmid vectors transfected into C2C12 mouse myoblast and myotube cultures. Intramuscular injection of EBV-based dystrophin expression plasmids into nude/mdx mice resulted in significant enhancement in the number of muscle fibres expressing recombinant dystrophin compared with a conventional vector. This effect was observed for over 10 weeks after a single administration. These results indicate the potential advantage of EBV-based expression vectors for focal plasmid-mediated gene augmentation therapy in Duchenne muscular dystrophy (DMD) and a range of other gene therapeutic applications.

Abstract
To better define the role of melatonin in fish, we have compared in detail the distribution of 2-[125I]iodomelatonin binding sites with gene expression for melatonin receptor subtypes in a widely studied seasonal species, the rainbow trout. Three distinct partial sequences of the melatonin receptor gene were cloned from trout genomic DNA. Two of the sequences corresponded to the Mella receptor subtype, and one corresponded to the Mellb receptor subtype. Analysis of numerous clones failed to find a sequence equivalent to the Mel1c receptor subtype. Comparison of receptor gene expression with 2-[125I]iodomelatonin binding distribution indicated dendritic transport of the receptor. Melatonin receptors were associated predominantly with visually related areas of the trout brain, such as the thalamic region, the pretectal area, and the optic tectum. The pituitary was devoid of 2-[125I]iodomelatonin binding, and melatonin receptor gene expression was not detectable. It would appear from the results of the present study that melatonin in this species is involved primarily in the processing of visual signals. How melatonin interacts with circannual rhythms of growth and reproduction is unclear, although a direct interaction between melatonin and the hypothalamo-pituitary axis is not clearly indicated.

Abstract
Inguinal hernia (IH) is relatively common in premature newborn infants, and the timing of surgical correction is controversial. We studied 40 premature infants who developed an IH and who were initially treated in a neonatal intensive care unit. Birth weight (BW) ranged from 492 to 2,401 g; 21 infants had a BW less than 1,000 g. The weight of the infants at operation ranged from 1,000 to 4,400 g. Twenty-one patients underwent herniotomy within 2 weeks after the diagnosis (short waiting group), in which 1 case of incarceration occurred; 19 waited longer than 2 weeks between diagnosis and surgery (long waiting group). Two cases of strangulation occurred in this latter group, and in 1 of those testicular necrosis occurred. Operation time was analysed in boys with bilateral herniotomy (n = 25): the short waiting group (n = 12) showed a significantly reduced operation time compared to the long waiting group (n = 13). Patients weighing less than 1,000 g at birth (n = 21) had a longer average waiting period for surgery. In the group of male patients with bilateral herniotomy, average operation time was longer in the group weighing less than 1,000 g at birth (n = 13) than in the group over 1,000 g (n = 12). Body weight at surgery did not affect operation time. It is concluded that early hernia repair should be considered in premature infants to avoid operative difficulties and gonadal ischaemia caused by incarceration.

Abstract
The authors evaluated the responsiveness of 4 preschool-aged children to positive reinforcers within a concurrent operants paradigm during mealtimes. The children were presented with two identical, concurrently available sets of food. Each set differed in quantity and quality of positive reinforcement paired with acceptance of each bite of food or in the number of bites of food required to obtain positive reinforcement. Experiment 1 evaluated 1 child's responsiveness to positive reinforcement while permitting escape from bite offers. Experiment 2 evaluated 2 children's responsiveness to positive reinforcement when escape extinction occurred. Results from these experiments suggested that the children were responsive to positive reinforcers and chose more often the bites paired with the greater quantity and/or quality of reinforcement. Experiment 3 evaluated 1 child's responsiveness to positive reinforcement both without and with escape extinction. Results suggested that positive reinforcement affected choice behavior and that escape extinction affected amount of food consumed.

Plasma apolipoprotein AI (apoAI) and lecithin-cholesterol acyltransferase (LCAT) play important roles in reverse cholesterol transport, promoting the removal of excess cholesterol from peripheral cells and reducing formation of atherosclerotic lesions. Gene augmentation of either apoAI or LCAT, or both, are thus attractive targets for prevention or treatment of atherosclerosis. With the eventual aim of safe and efficient gene delivery to skeletal muscle, our chosen secretory platform for systemic delivery of anti-atherogenic proteins, we have constructed conventional and AAV-based plasmid vectors containing human apoAI or LCAT cDNAs; their efficacy was tested by lipoplex transfection of mouse C2C12 muscle cells or human 293 cells. The secretion of apoAI or LCAT by transduced cultures was two- to five-fold higher using AAV-based plasmid vectors than conventional plasmid vectors. Additionally, cells transfected with a bicistronic AAV-based vector containing an internal ribosome entry site (IRES) efficiently expressed both apoAI and LCAT simultaneously. Furthermore, AAV-based vector sequences were retained by host cells, whereas those of conventional plasmid vectors were lost. These studies indicate that ectopic overexpression of apoAI and LCAT in muscle tissue using AAV-based plasmid vectors might provide a feasible anti-atherogenic strategy in vivo.

Abstract
As the population ages and becomes more frail, pressure ulcer prevalence and incidence within specific care settings are being evaluated through outcomes review. This article summarizes the process and outcomes of an ongoing prevalence study at a 300-bed acute care community hospital. All patients on the adult medical, surgical, and critical care units were examined regularly by the "Rear Admirals," a team comprising a skin care resource person and a nursing unit representative. The Total Quality Management model, characterized by the phrase "Plan-Do-Check-Act," was used to address barriers to quality care. Findings during that time prompted changes in policies, products, protocols, work assignments, and documentation tools. The outcomes achieved demonstrated the effectiveness of those strategies. After implementation of the Total Quality Management model at our Institution, the prevalence of patients with nosocomial pressure ulcers was reduced by 83%.

Abstract
Radiographic film is routinely used to obtain dosimetric information about therapy treatment beams. One source of inaccuracy is the variability of the chemical processing of the radiographic film. Several processors, film types and two sources (light and x-rays) were used to investigate the reproducibility of film processing for valid film dosimetry. Particular attention is paid to films commonly used in radiation therapy. The results suggest that for this series of film, given the same exposure, the variability in processing may result in an error of +/- 3.3% in optical density, which would lead to an error of +/- 4.4% in indicated dose. This level of inaccuracy is typical for both point and relative dose estimates. These results indicate that film should not be used as a point or relative dosimeter, unless the combination of film type, exposure, processing and reading have been specifically validated.

Abstract
Various sequences in the mammalian genomes are unstable. One class of sequence arrangement is long inverted repeats, which are known to be unstable in bacteria and yeast. While in mammals some evidence suggests that short inverted repeats (<10 bp long) may show instability, nothing is known about the stability of long inverted repeats. Here we describe two unrelated multicopy transgenes in the mouse (loci 109 and OX1-5), each of which contains a long inverted repeat that shows substantial mitotic instability. This instability also occurs in the germline so that mutant transgenes appear within pedigrees at a high frequency. The mutation processes acting at these two inverted repeats are complex and can involve insertion or deletion, and can result in stabilization of the transgene. At transgene 109 mutational events range from very small rearrangements at the centre of the inverted repeat to complete transgene deletion. In addition we show that the rates of mutation at the inverted repeat of transgene OX1-5 can vary between the male and female germlines and between inbred strains of mice, suggesting the possibility of a genetic analysis to identify loci that modulate inverted repeat instability.

Abstract
Day surgery for children is becomingly increasing common because of the advantages to children and their families, and the reduction in costs. However, community follow-up of children appears to be sporadic. The author conducted a survey of parents, day surgery nurses and community nurses to determine if a follow-up visit was necessary after day surgery for insertion of grommets. Just over three quarters of parents (77 per cent) said they could have coped without the visit, a view echoed by both groups of nurses. Furthermore, 54 per cent of parents felt the visit was not absolutely necessary. This leads to the conclusion that provision of this service needs reviewing.

Abstract
BACKGROUND Surgical procedures suppress host antitumor defense mechanisms, which may increase the risk of metastatic tumor dissemination. We have evaluated the effects of the biologic response modifier polyadenylic-polyuridylic acid (PAPU) on natural cytotoxicity in patients with breast cancer undergoing operation. METHODS PAPU (150 mg) or placebo was given intravenously during the perioperative period (preoperative, days -1 and 0; postoperative, days 1, 3, 5, 7, and 14). The function (chromium release assay) and number (flow cytometry) of natural killer (NK) cells were measured before operation (days -2 and -1), on the day of operation (day 0), and after operation (days 1, 2, 4, 6, and 18). RESULTS Surgical procedures suppressed NK cell cytotoxicity in the placebo group on postoperative days 1 (p < 0.001), 4, 6, and 18 (p < 0.05), whereas inhibition on postoperative day 2 failed to reach significance. PAPU abolished this immunosuppression after operation. The NK cell activity was elevated when compared with the control group; it was significant (p < 0.05) on postoperative days 1, 2, 4, 6, and 18. Surgical procedures also reduced circulating NK cell numbers during the first postoperative week in the placebo group; the decrease was statistically significant on day 4. The decrease in NK cell numbers in the PAPU group was insignificant. CONCLUSIONS PAPU prevented the decrease in the circulating number and cytotoxic activity of NK cells that occurred after operation and enhanced NK cell cytotoxicity. This may have important implications for patients with cancer undergoing major operation.

Abstract
A forced-choice preference assessment was conducted in which two dependent measures were used to select preferred stimuli: (a) approach responding and (b) latency to the first aberrant response. Stimuli identified as preferred based on both dependent measures were then evaluated during treatment. The results suggested that latency may be a useful measure in the selection of preferred stimuli during forced-choice assessments.

Abstract
We evaluated the separate components in treatment packages for food refusal of 4 young children. First, treatment packages were implemented until food acceptance improved. Next, a component analysis was conducted within a multielement or reversal design to identify the active components that facilitated food acceptance. The results indicated that escape extinction was always identified as an active variable when assessed; however, other variables, including positive reinforcement and noncontingent play, were also identified as active variables for 2 of the children. The results suggest that the component analysis was useful for identifying variables that affected food acceptance.
