Abstract
Background Prison-based hepatitis C treatment is safe and effective; however, many individuals are released untreated due to time or resource constraints. On community re-entry, individuals face a number of immediate competing priorities, and in this context, linkage to hepatitis C care is low. Interventions targeted at improving healthcare continuity after prison release have yielded positive outcomes for other health diagnoses; however, data regarding hepatitis C transitional care are limited. Methods We conducted a prospective randomized controlled trial comparing a hepatitis C care navigator intervention with standard of care for individuals released from prison with untreated hepatitis C infection. The primary outcome was prescription of hepatitis C direct-acting antivirals (DAA) within 6 months of release. Results Forty-six participants were randomized. The median age was 36 years and 59% were male. Ninety percent (n = 36 of 40) had injected drugs within 6 months before incarceration. Twenty-two were randomized to care navigation and 24 were randomized to standard of care. Individuals randomized to the intervention were more likely to commence hepatitis C DAAs within 6 months of release (73%, n = 16 of 22 vs 33% n = 8 of 24, P < .01), and the median time between re-entry and DAA prescription was significantly shorter (21 days [interquartile range {IQR}, 11–42] vs 82 days [IQR, 44–99], P = .049). Conclusions Care navigation increased hepatitis C treatment uptake among untreated individuals released from prison. Public policy should support similar models of care to promote treatment in this high-risk population. Such an approach will help achieve hepatitis C elimination as a public health threat.

Abstract
BackgroundThere is a newly emergent ageing population of people living with HIV (PLWH) in Africa. However, there is little research into HIV-associated neurocognitive disorder (HAND) in this population. Existing research suggests HAND is prevalent however the aetiology remains unclear. This study aims to determine whether HAND is truly prevalent and explore potential causes in PLWH on c-ART using objective structural measures.AimsExplore whether substantial atrophy and/or white matter hyperintensities (WMH) is present on the clinical magnetic resonance imaging (MRI) reports and quantitative analysis of people with optimally managed HIV in Northern Tanzania.Explore the aetiology of HAND by assessing whether cerebral atrophy and/or WMH is associated with demographic risk factors, HIV–related factors and/or comorbidities.Investigate whether structural damage is related to objectively measured cognitive impairment, and whether this is a subcortical or cortical impairment.Explore which neurocognitive test is the best predictor of structural damage and therefore most valid diagnostic test for HAND.MethodsA systematic sample of PLWH aged ≥ 50 were recruited from a HIV clinic in Kilimanjaro, Tanzania. Demographic data and comorbidities were self-reported. HIV-disease management data were obtained. Viral load and CD4 count were measured. A neurocognitive battery and informant history of functional impairment identified HAND. Cerebral atrophy (brain and ventricle volume) and WMH were measured using quantitative analysis of 1.5T MRI.Preliminary resultsThis cohort (n=91) had well-managed HIV (75.9% suppressed viral load, median CD4 507 cells/ul). The significant independent predictor (IP) of decreased brain volume was older age at HIV diagnosis (p=.001), and of increased ventricle volume was increased age (p<.0001), male gender (p<.0001) and increased frailty (p<.0001). The significant IPs of increased WMH volume were increased age (p<.0001) and smoking (p=.021). Only memory impairment independently predicted all structural measures.ConclusionsThis is the first MRI study of older c-ART treated PLWH in Africa. Despite c-ART and good disease management, HAND was objectively prevalent and unrelated to measures of HIV. Cerebral atrophy and WMH were associated with factors of neurodegeneration. Cerebral atrophy was associated with male gender and age at diagnosis (legacy effect).

Abstract
Background and aims Prison-based HCV treatment rates remain low due to multiple barriers, including accessing transient elastography for cirrhosis determination. The AST-to-platelet ratio index (APRI) and FIB-4 scores have excellent negative predictive value (NPV) in hospital cohorts to exclude cirrhosis. We investigated their performance in a large cohort of prisoners with HCV infection. Methods This was a retrospective cohort study of participants assessed by a prison-based hepatitis program. The sensitivity, specificity, NPV and positive predictive value (PPV) of APRI and FIB-4 for cirrhosis were then analysed, with transient elastography as the reference standard. The utility of age thresholds as a trigger for transient elastography was also explored. Results Data from 1007 prisoners were included. The median age was 41, 89% were male, and 12% had cirrhosis. An APRI cut-off of 1.0 and FIB-4 cut-off of 1.45 had NPVs for cirrhosis of 96.1% and 96.6%, respectively, and if used to triage prisoners for transient elastography, could reduce the need for this investigation by 71%. The PPVs of APRI and FIB-4 for cirrhosis at these cut-offs were low. Age ≤35 years alone had a NPV for cirrhosis of 96.5%. In those >35 years, the APRI cut-off of 1.0 alone had a high NPV >95%. Conclusion APRI and FIB-4 scores can reliably exclude cirrhosis in prisoners and reduce requirement for transient elastography. This finding will simplify the cascade of care for prisoners living with hepatitis C.

Abstract
Six mothers of visually impaired children participated in semi-structured interviews. Three dominant themes emerged: 1) emotional issues, particularly surrounding the period of diagnoses; 2) coping strategies, which included the mother's personality, the child's attitude, and the use of support networks; 3) problems and concerns about relationships with professionals, the child's education, people's attitudes, and the amount of time involved in parenting. These themes are discussed in depth and compared with the studies of parenting children with other types of disabilities. The need for further research is explored.

Abstract
We show unequivocal evidence for formation of He_{2}^{*} excimers in liquid He II created by ionizing radiation produced through neutron capture. Laser beams induce fluorescence of the excimers. The fluorescence is recorded at a rate of 55.6 Hz by a camera. The location of the fluorescence is determined with an uncertainty of 5 μm. The technique provides an opportunity to record the flow of He_{2}^{*} excimers in a medium with very small viscosity and enables measurement of turbulence around macroscopic liter size objects or vortex matter in three dimensions.

Abstract
BACKGROUND & AIMS Treatment programs for people who inject drugs (PWID), including prisoners, are important for achieving hepatitis C elimination targets. There are multiple barriers to treatment of hepatitis C in prisons, including access to specialist physicians, testing and antiviral therapy, short prison sentences, and frequent inter-prison transfer. We aimed to assess the effectiveness of a nurse-led model of care for the treatment of prisoners with hepatitis C. METHODS A statewide program for assessment and management of hepatitis C was developed in Victoria, Australia to improve access to care for prisoners. This nurse-led model of care is supported by telemedicine to provide decentralized care within all prisons in the state. We prospectively evaluated the feasibility and efficacy of this nurse-led model of care for hepatitis C within the 14 adult prisons over a 13-month period. The primary endpoint was sustained virological response at post-treatment week 12 (SVR12) using per protocol analysis. RESULTS There were 416 prisoners included in the analysis. The median age was 41 years, 90% were male, 50% had genotype 3 and 44% genotype 1 hepatitis C and 21% had cirrhosis. Injecting drug use was reported by 68% in the month prior to prison entry, 54% were receiving opioid substitution therapy, and 86% reported never previously engaging with specialist HCV care. Treatment duration was 8 weeks in 24%, 12 weeks in 59%, and 24 weeks in 17% of treatment courses. The SVR12 rate was 96% (301/313) per protocol. Inter-prison transfer occurred during 26% of treatment courses but was not associated with lower SVR12 rates. No treatment-related serious adverse events occurred. CONCLUSION Hepatitis C treatment using a decentralized, nurse-led model of care is highly effective and can reach large numbers of prisoners. Large scale prison treatment programs should be considered to support hepatitis C elimination efforts. LAY SUMMARY There is a high burden of hepatitis C infection among prisoners worldwide. Prisoners who continue to inject drugs are also at risk of developing new infections. For this reason, the prison setting provides an opportunity to treat those people at greatest risk of infection and to stop transmission to others. We developed a new method of providing hepatitis C treatment to prisoners, in which nurses rather than doctors assessed prisoners locally at each prison site. Treatment was safe and most prisoners were cured. Such programs will contribute greatly to achieving the World Health Organization's hepatitis C elimination goals.

Abstract
The polarized neutron imaging technique provides a non-invasive method of characterizing localized magnetic fields inside superconductors. However, complete understanding of the magnetic field distribution has yet to be realized experimentally due to the complexity of the interaction between neutron polarization and magnetic field. In this article, we show that a well-defined and controlled magnetic field through the neutron path contributes to simplify the data analysis and makes future quantitative polarized neutron imaging possible. This is demonstrated in a set of experiments that visualize the magnetic field distribution inside and around the superconductors. The experimental results demonstrate that proper guide field setup allows the visualization of the magnetic field expulsion at the surface of the superconductor in the zero-field cooling condition, as well as the magnetic field trapped inside the superconductor under field cooling condition.

Abstract
BACKGROUND All-soft suture anchors (ASSAs) are commonly used for shoulder labral repair and capsulorrhaphy in patients with shoulder instability. While these anchors may have some specific advantages over other types of suture anchors, little is known about the prevalence and time-dependence of bone cyst formation and tunnel expansion after implantation of ASSAs. The aim of this study was to quantify the proportions of cyst formation and tunnel expansion around ASSAs and to characterize and test for differences in abnormalities observed at different postoperative time points. METHODS Thirty patients who were treated with arthroscopic shoulder stabilization surgery with ASSAs (1.4 mm; JuggerKnot, Biomet) underwent a computed tomography (CT) scan of the operatively treated shoulder at 1 month (10 patients), 6 months (10 patients), or 12 months (10 patients) postoperatively. Demographic and operative data were collected, and CT scans were evaluated for cyst formation, tunnel expansion, and tunnel volume measured in cubic millimeters. Statistical analyses were performed to detect differences in these outcomes among the follow-up groups. All shoulders were stable at all time points of the study, and there were no incidents of recurrent instability during the study period. RESULTS Ninety-one suture anchors were evaluated in 30 patients. Tunnel expansion was identified in the large majority of patients in the 6-month and 12-month follow-up groups, with a significant increase in these proportions compared with the 1-month follow-up group (p = 0.002). Mean tunnel volumes also significantly increased over the study period (p < 0.001). The presence of cyst formation was negligible in all 3 follow-up cohorts. CONCLUSIONS This study demonstrated low rates of cyst formation but a significantly increased tunnel volume 6 and 12 months after shoulder labral surgery with ASSAs. There was no association with the initial tunnel location. Additional well-controlled studies with longer follow-up are needed to identify potential associations among tunnel expansion, intraoperative technique, and clinical outcomes. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
The urachus is a vestigial remnant of the allantois, which is normally obliterated during fetal life to become the median umbilical ligament, which runs between the urinary bladder and umbilicus in adults. Failure of obliteration leaves a tubular urachal remnant, which may present with disease. We report a unique case of a urachal remnant causing umbilical pain and in-drawing on micturition in a nine-year-old boy. There was no urine discharge from the umbilicus and in-drawing did not occur on defecation. His urinary stream was normal. High frequency ultrasonography revealed a thick band with a narrow, anechoic, fluid filled central channel. Exploration via an infraumbilical curvilinear incision identified a thick urachal band that could be traced to the dome of the bladder. This was excised flush with the bladder. The patient remains well at nine months following surgery with complete cessation of symptoms.

Abstract
BACKGROUND/AIMS Long-term follow-up studies validating the clinical benefit of sustained virological response (SVR) in people with chronic hepatitis C (CHC) infection are lacking. Our aim was to identify rates and predictors of liver fibrosis progression in a large, well characterized cohort of CHC patients in whom paired liver fibrosis assessments were performed more than 10 years apart. METHODS CHC patients who had undergone a baseline liver biopsy pre-2004 and a follow up liver fibrosis assessment more than 10 years later (biopsy or liver stiffness measurement (LSM) using transient elastography [FibroScan]) were identified. Subjects who had undergone a baseline liver biopsy but had no follow up fibrosis assessment were recalled for LSM. Fibrosis was categorised as mild-moderate (METAVIR F0-2 / LSM result of ≤ 9.5 kPa) or advanced (METAVIR F3-4/ LSM >9.5 kPa). The primary objective was to assess the association between SVR and the rate of liver fibrosis progression over at least 10 years, defined as an increase from mild-moderate fibrosis at baseline liver biopsy (METAVIR F0-2) to advanced fibrosis at follow-up liver fibrosis assessment. RESULTS 131 subjects were included in this analysis: 69% male, 82% Caucasian, 60% G1 HCV, 25% G3 HCV. The median age at F/U fibrosis staging was 57 (IQR 54-62) years with median estimated duration of infection 33-years (IQR 29-38). At F/U, liver fibrosis assessment was performed by LSM in 86% and liver biopsy in 14%. The median period between fibrosis assessments was 14-years (IQR 12-17). 109 (83%) participants had received interferon-based antiviral therapy. 40% attained SVR. At F/U, there was a significant increase in the proportion of subjects with advanced liver fibrosis: 27% at baseline vs. 46% at F/U (p = 0.002). The prevalence of advanced fibrosis did not change among subjects who attained SVR, 30% at B/L vs 25% at F/U (p = 0.343). However, advanced fibrosis became more common at F/U among subjects with persistent viremia: 10% at B/L vs 31% at F/U (p = 0.0001). SVR was independently associated with protection from liver fibrosis progression after adjustment for other variables including baseline ALT (p = 0.011), duration of HCV infection and mode of acquisition. CONCLUSION HCV eradication is associated with lower rates of liver fibrosis progression. The data support early treatment to prevent long-term liver complications of HCV infection.

Abstract
UNLABELLED Essentials Ignorance of direct oral anticoagulants' effects on coagulation tests may be a safety issue. An electronic questionnaire was sent to prescribers in NHS Grampian with 143 respondents. We found widespread evidence of inappropriate interpretation of the clinical scenarios given. The study suggests potential for patient harm due to lack of knowledge and education is required. SUMMARY Background Lack of awareness of the nature of the direct oral anticoagulants (DOACs) combined with the poor correlation between routine coagulation test prolongation and the activity of these drugs represents a potential for patient harm. Objectives To establish the level of awareness of the different DOACs, and to assess whether prescribers were able to recognize the state of anticoagulation in a hypothetical patient. Methods and results An electronic questionnaire was sent by email to prescribers in our health board. Among 143 respondents, we found significant differences in awareness of the currently licensed drugs. Of the respondents, 88%, 80% and 50%, respectively, recognized rivaroxaban, dabigatran, and apixaban. When provided with a routine clinical situation, only 13.5%, 17.5% and 16.8%, respectively, recognized that the hypothetical patient was anticoagulated, and only 55-58% recognized that it was unsafe to proceed with an invasive procedure. Conclusion These results indicate a significant risk for patient harm related to lack of knowledge about this new group of frequently used drugs, and indicate that additional education and training on this subject are required.

Abstract
BACKGROUND Shorter sleep is a risk factor for weight gain in young children. Experimental studies show that sleep deprivation is associated with higher nighttime energy intake, but no studies have examined the patterning of energy intake in relation to nighttime sleep duration in young children. OBJECTIVES The objectives of the study were to test the hypothesis that shorter-sleeping children would show higher nighttime energy intake and to examine whether the additional calories were from drinks, snacks or meals. METHODS Participants were 1278 families from the Gemini twin cohort, using data from one child per family selected at random to avoid clustering effects. Nighttime sleep duration was measured at 16 months of age using the Brief Infant Sleep Questionnaire. Energy intake by time of day and eating episode (meal, snack, drink) were derived from 3-day diet diaries completed when children were 21 months. RESULTS Consistent with our hypothesis, shorter-sleeping children consumed more calories at night only (linear trend P < 0.001), with those sleeping <10 h consuming on average 120 calories (15.2% of daily intake) more at night than those sleeping ≥13 h. The majority of nighttime intake was from milk drinks. Associations remained after adjusting for age, sex, birth weight, gestational age, maternal education, weight and daytime sleep. CONCLUSIONS Shorter-sleeping, young children consume more calories, predominantly at night, and from milk drinks. Parents should be aware that providing milk drinks at night may contribute to excess intake. This provides a clear target for intervention that may help address associations between sleep and weight observed in later childhood.

Abstract
Background: Higher food intake is implicated in the elevated risk of obesity associated with shorter sleep in children, but the mechanisms driving higher intake are uncertain. Research in adults suggests that acute sleep deprivation affects brain reward systems, which increases responsiveness to palatable foods. However, there have been few studies addressing habitual sleep duration, and few in children, among whom the strongest associations with body mass index (BMI) are seen. Objective: The objective of this study is to test the hypothesis that shorter-sleeping children are more food responsive and explore the mediation of the relationship between sleep and weight by food responsiveness (FR). Methods: Participants were families from Gemini, a UK twin birth cohort, who had provided complete information on their children's sleep and appetite at age 5 years (n=1008). One child from each twin pair was randomly selected for analyses. Nighttime sleep duration was calculated from parent-reported bedtime and wake time, and categorised as shorter, adequate or longer according to age-specific reference values. FR was assessed with the Child Eating Behaviour Questionnaire. BMI s.d. scores (BMI-SDS) were calculated from parent-measured heights and weights using the UK 1990 reference data and were available for 494 children. Results: There was a significant linear association between shorter sleep and higher FR at age 5 years (P for linear trend=0.032), which was maintained after adjusting for age, sex, birth weight, maternal education and BMI-SDS. In the subset with BMI data at age 5 years, shorter sleep was associated with higher BMI-SDS (P=0.026) as expected. Testing for mediation by adding FR to the model attenuated the linear relationship to borderline significance (P=0.049), suggesting partial mediation. Conclusions: Shorter sleep in childhood is associated with higher FR, which may partly explain the association between shorter sleep and adiposity in childhood.

Abstract
BACKGROUND Identification and control of multi-jurisdictional foodborne illness outbreaks can be complex because of their multidisciplinary nature and the number of investigative partners involved. OBJECTIVE To describe the multi-jurisdictional outbreak response to an E. coli O157:H7 outbreak in Canada that highlights the importance of early notification and collaboration and the value of centralized interviewing. METHODS Investigators from local, provincial and federal jurisdictions, using a national outbreak response protocol to clarify roles and responsibilities and facilitate collaboration, conducted a rapid investigation that included centralized re-interview of cases, descriptive methods, binomial probability, and traceback findings to identify the source of the outbreak. RESULTS There were 31 laboratory confirmed cases identified in New Brunswick, Nova Scotia, and Ontario. Thirteen cases (42%) were hospitalized and one case (3%) developed hemolytic uremic syndrome; there were no deaths. Due to early notification a coordinated investigation was initiated before laboratory subtyping was available. Re-interview of cases identified 10 cases who had not initially reported exposure to the source of the outbreak. Less than one week after the Outbreak Investigation Coordinating Committee was formed, consumption of shredded lettuce from a fast food chain was identified as the likely source of the illnesses and the implicated importer/processor initiated a precautionary recall the same day. CONCLUSION This outbreak investigation highlights the importance of early notification, prompt re-interviewing and collaboration to rapidly identify the source of an outbreak.

Abstract
Background And Objectives: Shorter sleep is associated with higher weight in children, but little is known about
the mechanisms. The aim of this study was to test the hypothesis that shorter sleep was
associated with higher energy intake in early childhood. Methods: Participants were 1303 families from the Gemini twin birth cohort. Sleep duration was
measured using the Brief Infant Sleep Questionnaire when the children were 16 months
old. Total energy intake (kcal per day) and grams per day of fat, carbohydrate and
protein were derived from 3-day diet diaries completed by parents when children were 21
months old. Results: Shorter nighttime sleep was associated with higher total energy intake (P for
linear trend=0.005). Children sleeping <10 h consumed around
50 kcal per day more than those sleeping 11–<12 h a night (the
optimal sleep duration for children of this age). Differences in energy intake were
maintained after adjustment for confounders. As a percentage of total energy intake,
there were no significant differences in macronutrient intake by sleep duration. The
association between sleep and weight was not significant at this age
(P=0.13). Conclusions: This study provides the first evidence that shorter nighttime sleep duration has a
linear association with higher energy intake early in life. That the effect is observed
before emergence of associations between sleep and weight indicates that differences in
energy intake may be a mechanism through which sleep influences weight gain.

Abstract
Background and aims This paper aims at correcting misinformation in circulation portraying Mary Seacole as a nurse, Crimean War heroine, and health care pioneer, even, for some, a replacement for Florence Nightingale, who really was a health care pioneer as well as being the major founder of the modern profession of nursing. Methods and results The article focuses on the claims for Seacole made by C. Short in Scottish Medical Journal, 2011. It reports, using primary sources, on what Seacole actually did – running a business for officers, with kind acts on the side – short of constituting heroism, pioneering health care or nursing. Conclusion The article concludes with remarks on how Nightingale came to be forgotten as a health care pioneer, with comments on the two major sources that attacked her reputation, F.B. Smith in 1982, and Hugh Small in 1998. Detailed refutations in peer-reviewed sources are referenced. Finally, it is suggested that recent scandals in English hospital care, documented in the Francis Report, may provoke a revival of interest in Nightingale’s principles and methods.

Abstract
Overcorrection is a widely used behavior management procedure, the success of which has been well documented. However, overcorrection is not a simple, single procedure. Rather, it is a complex combination of procedures that often make it a complicated strategy to understand conceptually and to implement correctly. The complex nature of overcorrection combined with the use of multiple labels has created much confusion and debate among both researchers and practitioners. A number of issues relating to overcorrection are examined and evaluated. A proposal is made for revising the present overcorrection terminology. Finally, directions for future research are suggested.

Abstract
Identification of methionine aminopeptidase-2 (MetAP-2) as the molecular target of the antiangiogenic compound TNP-470 has sparked interest in N-terminal Met excision's (NME) role in endothelial cell biology. In this regard, we recently demonstrated that MetAP-2 inhibition suppresses Wnt planar cell polarity (PCP) signaling and that endothelial cells depend on this pathway for normal function. Despite this advance, the substrate(s) whose activity is altered upon MetAP-2 inhibition, resulting in loss of Wnt PCP signaling, is not known. Here we identify the small G protein Rab37 as a MetAP-2-specific substrate that accumulates in the presence of TNP-470. A functional role for aberrant Rab37 accumulation in TNP-470's mode of action is demonstrated using a Rab37 point mutant that is resistant to NME, because expression of this mutant phenocopies the effects of MetAP-2 inhibition on Wnt PCP signaling-dependent processes.

Abstract
Liver concentrations of selected pollutant classes were determined in groups of sheep fetuses and their dams, at 55 (Experiment 1) and 110 (Experiment 2) days of gestation (term = 145 d) following exposure, throughout their breeding lives and after mating, to pasture treated with either inorganic fertiliser (control, CC) or with sewage sludge (treated, TT). In a unique study designed to separate the respective contributions of environmental sources and mobilised tissue to the available EDC burden, in additional groups of animals, pollutant burdens at 110 days gestation were assessed following exposure to the respective treatments, either throughout their breeding lives until mating, but not thereafter (TC), or only between mating and slaughter (CT) (Experiment 3). With very few exceptions, maternal and fetal liver concentrations of diethylhexyl phthalate (DEHP) and selected polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDE) and polycyclic aromatic hydrocarbons (PAHs) were not significantly affected by sludge exposure in any group. In some cases, maternal and fetal tissue EDC concentrations were different but the differences were not consistent, and maternal and fetal concentrations of none of the classes of chemical were significantly correlated. It was not possible to identify a single chemical, or class of chemical, that may be responsible for previously observed physiological effects of exposure to sludge-treated pastures. It is concluded that exposure of sheep to pastures fertilised with sewage sludge was not associated with increased liver concentrations of EDCs, irrespective of the stage of development at which they were measured and of maternal tissue mobilisation and EDC release during gestation. Thus, retrospective measurements of EDC tissue burdens could not be used to accurately assess earlier fetal EDC insults.

Abstract
Fetal tissue concentrations of endocrine disrupting compounds (EDCs), and their relationship to maternal tissue concentrations, are largely unknown, in any species. In particular, the patterns of accumulation in the respective tissues following increased rates of environmental exposure are little known. This study was designed to determine fetal and maternal tissue concentrations of selected EDCs in sheep exposed to background, environmental concentrations of EDCs (pastures treated with inorganic fertiliser; Control; C) or to elevated, environmental concentrations (sludge-treated pastures; Treated; T). Mean log concentrations of diethylhexyl phthalate (DEHP) were similar in adult and fetal livers but there was a significant interaction between stage of development (maternal or fetal) and treatment reflecting the fact that mean concentrations were lower (P < 0.05) in C than T fetuses but not adults. Relative concentrations of polychlorinated biphenyls (PCB) in maternal and fetal tissue differed with congener; concentrations of congener 101 were higher (P < 0.05) in fetal tissue. Neither maternal nor fetal liver concentrations of any of the PCB congeners differed significantly with treatment. Polybrominated diphenyl ethers (PBDE) in the tissue were represented primarily by congeners 47 and 99. PBDE 99 concentrations were higher in maternal than fetal tissue (P = 0.01). None differed with treatment in either maternal or fetal tissues. Concentrations of many polycyclic aromatic hydrocarbons (PAH) were higher in maternal tissue but none differed with treatment in either adult or fetuses. It is concluded that sheep fetal liver EDC concentrations are variably related to those of their dams and in some cases appear to be selectively accumulated in fetuses. Differential accumulation of individual pollutants may have important implications for the assessment of risk from exposure.

Abstract
This study, conducted in Newfoundland and Labrador, assessed the level of awareness, perceptions and concerns of healthcare providers, health researchers, data managers and the general public about the collection, use and disclosure of personal health information (PHI) for research purposes. Data collection involved surveys and follow-up focus groups with participants. Results indicate a poor understanding generally with regard to privacy rights and responsibilities. Many professionals are unfamiliar with the legislative environment for PHI, particularly as it pertains to the access and use of PHI for research purposes. Lack of familiarity with basic requirements for patient-based research, coupled with heightened sensitivity to privacy issues owing to various federal and provincial regulatory initiatives, could have a chilling effect on health research. Importantly, our results indicate that the public is much less concerned about the use of their PHI for health research purposes than are professionals who collect, store and share it.
