ABSTRACT

Indigenous peoples in Canada and other settler colonial nations experience barriers to healing in the health care system and their communities. Drawing on four sequential sharing circles and indepth interviews with 11 Indigenous men, this article shares the stories of Indigenous men and their healing journeys with the aim of improving culturally safe support in the community. In sharing their stories, these men identified coping with colonialism, as well as trauma and grief, as barriers in their healing journey. They also described finding strength in cultural role models, fathering, as well as ceremony and connecting to the land. We discuss the implications of these findings for service provision and decolonizing community health services.

ABSTRACT

Preschool children with autism spectrum disorder (ASD) experience slower development of daily living skills (DLS) that are essential for independent functioning compared to typically developing children. Few studies have examined the trajectories of DLS in preschoolers with ASD and the existing literature has reported conflicting results. This study examined DLS trajectories and potential covariates for preschoolers with ASD from a multi-site longitudinal study following children from diagnosis to the end of grade 1. Multi-level modeling was conducted with DLS domain scores from the Vineland Adaptive Behavior Scales-2. The results demonstrated a positive trajectory of increasing scores over time, associations of age of diagnosis, developmental level, stereotypy, and language skills with the mean score at T4 or age 6 years, whereas rate of change was only associated with ASD symptom severity, such that an improvement in DLS trajectory was associated with lower and improving ASD symptom severity.

ABSTRACT

The prevalence of hypertension in children is increasing globally. Addressing this will require a robust understanding of associated risk factors. To this end, we conducted a systematic review to identify correlates of elevated blood pressure (BP) in children. Literature searches were conducted using pre-defined search terms from three academic databases. The abstract and full text of identified studies were screened for eligibility by two independent reviewers. A total of 100 studies were included in this systematic review. An assessment tool was first used to assess study quality; a narrative synthesis was then performed. We found a broad range of physiological, social and behavioural factors associated with elevated BP in children. The most common correlate observed was adiposity, suggesting that childhood obesity may be implicated in the increased prevalence of hypertension observed in children. However, the broad range of other factors identified underscores the multi-factorial aetiology of hypertension. Data from a broad range of studies showed that the correlates of hypertension in children are multi-factorial. Therefore, approaches aimed at preventing hypertension must in turn be multi-factorial to ensure that the burden of hypertension in childhood is addressed.

ABSTRACT

OBJECTIVE: To describe services received by preschool children diagnosed with autism spectrum disorder (ASD) during the five-year period following their diagnosis. METHOD: An inception cohort of preschoolers diagnosed with ASD from Halifax (Nova Scotia), Montreal (Quebec), Hamilton (Ontario), Edmonton (Alberta) and Vancouver (British Columbia) were invited to participate. Parents/caregivers (n=414) described the services provided to their children at four time points: baseline (T1; within four months of diagnosis; mean age three years); six months later (T2); 12 months later (T3); and at school entry (T4). Data were first coded into 11 service types and subsequently combined into four broader categories (no services, behavioural, developmental and general) for analysis. RESULTS: More than 80% of children at T1, and almost 95% at T4 received some type of service, with a significant number receiving >1 type of service at each assessment point. At T1, the most common service was developmental (eg, speech-language therapy). Subsequently, the most common services were a combination of behavioural and developmental (eg, intensive therapy based on applied behaviour analysis and speech-language therapy). Service provision varied across provinces and over time. DISCUSSION: Although most preschool children with ASD residing in urban centres were able to access specialized services shortly after diagnosis, marked variation in services across provinces remains a concern.


OBJECTIF: Décrire les services qu'ont reçus des enfants d'âge préscolaire ayant un trouble du spectre autistique (TSA) pendant la période de cinq ans suivant leur diagnostic. MÉTHODOLOGIE: Une cohorte initiale d'enfants d'âge préscolaire ayant un TSA diagnostiqué et qui provenaient de Halifax (Nouvelle-Écosse), de Montréal (Québec), de Hamilton (Ontario), d'Edmonton (Alberta) ou de Vancouver (Colombie-Britannique) a été invitée à participer à l'étude. Les parents et les tuteurs (n=414) ont décrit les services fournis à leur enfant à quatre moments : au début (T1; dans les quatre mois suivant le diagnostic, âge moyen de trois ans); six mois plus tard (T2); 12 mois plus tard (T3) et à l'entrée à l'école (T4). Les chercheurs ont d'abord codé les données en 11 types de services, pour ensuite les regrouper en quatre catégories plus vastes (absence de services, comportementaux, développementaux et généraux) en vue de leur analyse. RÉSULTATS: Plus de 80 % des enfants ont reçu certains services à T1, et près de 95 % à T4, et un nombre significatif a reçu plus d'un type de services à chaque évaluation. À T1, le service le plus courant était de type développemental (p. ex., orthophonie). Par la suite, les services les plus courants étaient un mélange de services comportementaux et développementaux (p. ex., thérapie intensive selon l'analyse de comportement appliquée et orthophonie). La prestation des services variait selon les provinces et au fil du temps. EXPOSÉ: Même si la plupart des enfants d'âge préscolaire ayant un TSA qui habitaient dans un centre urbain avaient accès à des services spécialisés peu après le diagnostic, les variations marquées des services entre les provinces demeurent préoccupantes.

ABSTRACT

Children with autism spectrum disorder (ASD) and structural language impairment (LI) may be at risk of more adverse social-developmental outcomes. We examined trajectories of early social competence (using the Vineland-II) in 330 children aged 2-4 years recently diagnosed with ASD, and compared 3 subgroups classified by: language impairment (ASD/LI); intellectual disability (ASD/ID) and ASD without LI or ID (ASD/alone). Children with ASD/LI were significantly more socially impaired at baseline than the ASD/alone subgroup, and less impaired than those with ASD/ID. Growth in social competence was significantly slower for the ASD/ID group. Many preschool-aged children with ASD/LI at time of diagnosis resembled "late talkers" who appeared to catch up linguistically. Children with ASD/ID were more severely impaired and continued to lag further behind.

ABSTRACT

OBJECTIVES: To examine temporal trends in the use of vault cytology tests in primary and secondary care and the demographics of those women tested. METHODS: Retrospective analysis of routinely collected data concerning women who had a vault cytology test processed during a 10-year period (1 April 1995 to 31 March 2005) at Birmingham Women's NHS Foundation Trust. RESULTS: A total of 8457 vault cytology tests from 3164 women (range 1-17 tests, median = 2) were processed, representing approximately 2% of the cervical cytology workload of the Department of Cytopathology at Birmingham Women's Hospital. There was a significant reduction in annual numbers processed (Pearson correlation -0.958, P < 0.001). Significant abnormalities (mild dyskaryosis or worse) were detected in 4.5%, with malignancy being detected in <0.1%. The unsatisfactory cytology test rate was 10.7% overall. There was a reduction in the numbers of vault cytology tests coming from the community, hospital outpatient clinics and operating theatres over time (χ(2) for linear trend = 139.53, 9 d.f., P < 0.0001). Tests originating from community settings had the lowest disease detection rates: no malignancies and only two severe abnormalities were detected from almost 4000 primary care samples; abnormal results represented 2.8% (n = 113), of which the majority (n = 73) were borderline results. All cancers (n = 8) were detected in samples taken in gynaecology and colposcopy clinics. CONCLUSIONS: Vault cytology test usage appears to be reducing, particularly from outpatient clinics and primary care. Community detection rates are very low. Further research is required to establish the true costs and benefits of vaginal vault cytology.

ABSTRACT

The BSCC terminology was originally published in 1986 and although highly successful, requires revision. Through a process of professional consensus and literature review this has been undertaken by the BSCC. The revision takes account of recent developments and improvements in understanding of morphology and disease process and is compatible with other terminologies in use elsewhere, whilst still maintaining a focus on practice in the UK cervical screening programmes.

ABSTRACT

BACKGROUND: Vaginal vault smears are used to detect persisting neoplasia of the lower genital tract after hysterectomy. Recent data suggest both widespread use and uncertain evidence of their effectiveness. OBJECTIVES: To identify and synthesise evidence on the use and effectiveness of vaginal vault smears and to assess the quality. SEARCH STRATEGY 'vault smear' OR 'vaginal vault smear' OR 'cervical vault smear' OR ('Hysterectomy') AND ('Follow up' OR 'Smear'). SELECTION CRITERIA Primary research, women who had a hysterectomy and were followed up by vault cytology. DATA COLLECTION AND ANALYSIS: Systematic search (eight electronic databases), supplemented by contact with experts and review of bibliographies. Two independent reviewers determined eligibility/validity and extracted data concerning test performance characteristics. Quality was assessed according to the established criteria. RESULTS: Of 441 unique references, only 19 were suitable. Quality of studies varied considerably and few were of 'high' methodological quality. Studies were geographically diverse, and were published over more than 40 years in 16 journals. From the higher scoring papers, there were 11 659 hysterectomies [6546, benign; 76, cervical intraepithelial neoplasia (CIN) I/CIN II; 5037, CIN III]. Proportions of abnormal vault smears and abnormal biopsies during follow up increased with worsening histology at hysterectomy (P < 0.0001 and P = 0.0001). There was only one report of vaginal cancer subsequent to hysterectomy for CIN and insufficient data to allow for reliable meta-analysis. CONCLUSIONS: Vault smears cause anxiety, consume resources and their value is largely unproven. Inconsistency of study design and limited methodological quality means that the value of vault smears could not be established. High-quality research is required to ensure that the guidelines are evidence based.

ABSTRACT

BACKGROUND: Hyperplastic mesonephric remnants are an incidental finding in occasional uterine or cervical surgical specimens. We describe three cases in which such remnants were postulated to be the source of abnormal glandular cells in cervical smears. CASES: In all three cases abnormal glandular cells were seen in cervical smears. Subsequent histology showed the presence of hyperplastic mesonephric remnants that communicated with the endocervical canal and were likely to be the source of the abnormal glandular cells. We believe that the key features of these cells, which may aid their distinction from other causes of glandular abnormalities, are their loose clustering, lack of significant anisocytosis and cuboidal outlines. CONCLUSION: We aim to document mesonephric hyperplasia as a possible source for abnormal glandular cells in cervical smears.

ABSTRACT

BACKGROUND: The vaginal vault smear is a test for cellular atypia in women who have undergone a hysterectomy. In asymptomatic women the test has poor sensitivity and specificity. Current guidelines recommend: vault smears should not be used after hysterectomy for benign pathology; two vault smears (6 and 12 months postsurgery) should be taken when there is evidence of completely excised CIN II/III in the specimen. AIM: To describe primary health care professionals' self-reported knowledge and behaviour relating to the use of vault smears. DESIGN OF STUDY: Questionnaire. SETTING: South Birmingham. METHODS: Postal questionnaire survey to primary health care professionals (general practitioners and practice nurses, n = 424). RESULTS: Response rate 80.0%, completed response rate 68.9%. Mean knowledge score was 7.3 out of possible 12 (SD 1.9); range 0-10. No significant differences were observed between GPs and practice nurses in knowledge scores, although differences were noted in the frequency of performing vault smears. An inverse relationship was observed between frequency of performing vault smears and level of knowledge about the test. There was a positive association between requesting further information and the 'knowledge score'. Only 11% correctly answered a question based on current guidelines. CONCLUSIONS: Knowledge of current guidelines was poor. Those who undertook fewest vault smears appeared best informed. This suggests that if all primary care professionals practised according to current guidelines, the number of vault smears performed may be reduced. Unnecessary vault smears may cause additional anxiety in women and have financial consequences for the NHS.

ABSTRACT

For the cytologist and clinician alike, glandular lesions pose possibly the greatest challenge in cervical screening. Worldwide, with increasing confidence in cytological prediction, terminology is evolving. In the UK, with the adoption of liquid based methods, the technical aspects of cervical cytology are being addressed, it is now time to standardise our terminology in glandular reporting. Consideration of the cytological complexity, clinical needs and international protocols is essential in this endeavour.

ABSTRACT

The process of new blood vessel formation within and around neoplastic tissue, termed angiogenesis, is a significant factor in the development, progression and metastasis of malignant tumours in all species. A major cause of death in cancer patients is the development of treatment-resistant metastatic disease, which may be avoided by therapies that target the genetically stable population of vascular endothelial cells within tumours. Tumstatin is a small protein formed by the cleavage of the alpha-3 subunit of the non-collagenous domain of mammalian type IV collagen. Recombinant human Tumstatin has been shown to have potent angiostatic properties in vitro and in vivo. Tumstatin is a potent initiator of apoptosis and inhibits the proliferation and migration of vascular endothelial cells in cell culture. Recently, a fragment of Tumstatin, termed Tum5, has been shown to have biologic activity similar to the parent compound. The systemic administration of angiostatic proteins like Tum5 may result in the remission of established tumours, while preventing or delaying the onset of clinically detectable metastasis. Recombinant canine Tum5 (cTum5) was cloned and its protein expression induced in a prokaryotic vector. The resulting cTum5 protein caused dose-dependent inhibition of vascular endothelial cells in vitro, which appears to be mediated through apoptosis.

ABSTRACT

The ability to synthesize capped RNA transcripts in vitro using bacteriophage polymerases has been of considerable value in a variety of applications. However, Pasquinelli et al. [RNA (1995) 1:957-967] found that one-third to one-half of the caps are incorporated in the reverse orientation, that is, with the m7G moiety of m7GpppG linked by a 3'-5' phosphodiester bond to the first nucleotide residue of the RNA chain. Such reverse caps are unlikely to be recognized by eIF4E, based on previous studies, and thus complicate any comparison of the translational efficiencies of in vitro-synthesized mRNAs. We therefore designed two novel cap analogs, P(1)-3'-deoxy-7-methyguanosine-5' P3-guanosine-5' triphosphate and P(1)-3'-O,7-dimethylguanosine-5' P3-guanosine-5' triphosphate, that are, theoretically, incapable of being incorporated in the reverse orientation. The key reactions of pyrophosphate bond formation were achieved in anhydrous dimethylformamide solutions employing the catalytic properties of zinc salts. Structures were proven by 1H NMR. Transcripts produced with SP6 polymerase using "anti-reverse" cap analogs (ARCAs) were of the predicted length and indistinguishable in size and homogeneity from those produced with m7GpppG or GpppG. Analysis of the transcripts with RNase T2 and tobacco acid pyrophosphatase indicated that reverse caps were formed with m7GpppG but not with ARCAs. Both of the ARCAs inhibited cell-free translation with a K(I) similar to that of m7GpppG. Finally, the translational efficiency of ARCA-capped transcripts in a rabbit reticulocyte lysate was 2.3- to 2.6-fold higher than that of m7GpppG-capped transcripts. This suggests the presence of reverse caps in conventional in vitro-synthesized mRNAs reduces their translational efficiency.

ABSTRACT

Conduct disorder (severe and persistent antisocial behaviour in children and youth) is an important community mental health problem in Canada and has been the focus of considerable recent public policy debate. Good research evidence is available on effective (and ineffective) interventions for conduct disorder. Paradoxically, however, relatively little of the research evidence is incorporated into policy decision-making. There is a policy-research gap. An example (Hamilton, Ontario) is used to illustrate this gap. The gap is then explained using a framework for health policy analysis that incorporates values, institutional structures, and information. Values and institutional structures greatly outweigh research evidence in influencing current Canadian policy-making for the problem of conduct disorder. Possibilities for improving the situation are suggested.
