Assessing the Risk of Australian Indigenous Sexual Offenders Reoffending: A Review of the Research Literature and Court Decisions.

The assessment of offenders' risk of reoffending, particularly sexual reoffending, is a core activity of forensic mental health practitioners. The purpose of these assessments is to reduce the risk of harm to the public, but they are controversial and become more contentious when Australian practitioners who want to undertake such assessments in an ethically responsible way must use reliable validated instruments, disclose the limitations of their assessment methods, instruments and data to judicial decision-makers and understand how decision-makers might use their reports. The purpose of this systematic literature review was to explore the practices of Australian practitioners and courts in respect of the assessment of Australian Indigenous male sexual offenders' risk of reoffending. We could not identify an instrument that has been developed for the assessment of this population group. Australian courts differ in whether they admit and give weight to practitioners' evidence and opinions based on data obtained with non-validated instruments. We could only identify three possible predictor variables with enough quantitative support to justify including them in an instrument that could be used to assess Indigenous sexual offenders. There is a need for research regarding the validity of the instruments that practitioners use.

Microvillous tip vesicles may be an origin of placental extracellular vesicles.

INTRODUCTION: Extracellular vesicles are now believed to be important mediators of placental-maternal communication. However, little is known about the formation of extracellular vesicles by human placenta. This study uses nanoscale three-dimensional imaging to investigate how and where placental extracellular vesicles form. METHODS: Term and first trimester human placental villi were imaged by serial block face scanning electron microscopy. These images were analysed to quantify vesicle surface density. Segmentation was performed to reconstruct three-dimensional images of extracellular vesicles. Live imaging light microscopy of first trimester villous explants was performed. RESULTS: Vesicles were observed on the tips of placental microvilli in term and first trimester placenta. In term placenta these microvillous tip vesicles had a median size of 0.55 µm and their surface area density exceeded 22000 per mm2. Microvillous tip vesicle membranes had a lower electron density than the microvillous plasma membrane. Thirty seven percent of vesicles had a complex membrane structure including double membranes, internal vesicles and vesicle chains. Budding of smaller secondary vesicles from microvillous tip vesicle membranes was observed. Live imaging of a first trimester villus explant observed formation of vesicles which were larger but visually similar to the secondary vesicles observed by electron microscopy. DISCUSSION: These observations suggest that extracellular vesicles are forming on the tips of placental microvilli prior to release into maternal blood. However, it cannot be discounted that there are maternal extracellular vesicles that have bound to microvilli. In either case, the high surface area density of microvillous tip vesicles is consistent with an important role in placental-maternal signalling.

Characteristics and outcome of infants with bronchopulmonary dysplasia established on long-term ventilation from neonatal intensive care.

INTRODUCTION: Ex-preterm infants with severe bronchopulmonary dysplasia (BPD) sometimes require long-term ventilation (LTV) to facilitate weaning from respiratory support. There are however limited data characterizing this cohort. We aim to describe the background characteristics, neonatal comorbidities, characteristics at the initiation of ventilation, and outcomes of neonatal unit graduates with BPD established on LTV. METHODS: A retrospective cohort study of infants born <32 weeks gestation with BPD referred to a regional LTV service between January 2015 and December 2020. RESULTS: Twenty-five infants were referred during the study period. Median birth gestation was 26 + 1 weeks (24 + 0-30 + 4) and birth weight 645 g (430-1485). At 36 weeks postmenstrual age (PMA), median FiO2 was 0.45 (0.24-0.80) and one-quarter of infants remained on invasive ventilation. Twenty (80%) infants were established on noninvasive ventilation (NIV), with the smallest weighing 2085 g, and five (20%) required tracheostomy invasive ventilation (TIV). At initiation of NIV/TIV, median PMA was 41 + 1 weeks and median FiO2 0.40 (0.29-0.80). Infants established on TIV spent almost five times longer in hospital before discharge compared to those on NIV (p = 0.003). By March 2022, 18 (72%) infants had discontinued ventilation, spending a median total time of 113 days (18-1792) on ventilation. CONCLUSION: Due to advances in interfaces, headgear, and ventilator technology, NIV is an attractive and practically achievable option for infants with severe BPD as small as 2 kg. Initiation and weaning should take place in a facility with the required multidisciplinary expertize.

How and why do South Asians attend GUM clinics? Evidence from contrasting GUM clinics across England.

BACKGROUND: Improving access to sexual healthcare is a priority in the UK, especially for ethnic minorities. Though South Asians in the UK report low levels of sexual ill health, few data exist regarding their use of genitourinary medicine (GUM) services. OBJECTIVES: To describe reasons for attendance at GUM clinics among individuals of South Asian origin relative to patients of other ethnicities. METHODS: 4600 new attendees (5% South Asian; n=226) at seven sociodemographically and geographically contrasting GUM clinics across England completed a questionnaire between October 2004 and March 2005, which were linked to routine clinical data. RESULTS: South Asians were more likely than other groups to be signposted to the GUM clinic by another health service-for example, in women 14% versus 8% respectively (p=0.005) reported doing so from a family planning clinic. These women also reported that they would be less likely to go to the clinic if their symptoms resolved spontaneously compared with other women (51% vs 31%, p=0.024). However, relative to other clinic attendees, no differences in the proportions of South Asians who had acute STI(s) diagnosed at clinic were noted. Furthermore, South Asian men were more likely to report as their reason for attendance that they wanted an HIV test (23.4% vs 14.8%, p=0.005). CONCLUSION: Despite having similar STI care needs to attendees from other ethnic groups, South Asians, especially women, may be reluctant to seek care from GUM clinics, especially if their symptoms resolve. Sexual health services need to develop locally-delivered and culturally-appropriate initiatives to improve care pathways.

Understanding the burden of bacterial sexually transmitted infections and Trichomonas vaginalis among black Caribbeans in the United Kingdom: Findings from a systematic review.

BACKGROUND: In the UK, people of black Caribbean (BC) ethnicity continue to be disproportionately affected by bacterial sexually transmitted infections (STIs) and Trichomonas vaginalis (TV). We systematically reviewed evidence on the association between bacterial STIs/TV and ethnicity (BC compared to white/white British (WB)) accounting for other risk factors; and differences between these two ethnic groups in the prevalence of risk factors associated with these STIs, sexual healthcare seeking behaviours, and contextual factors influencing STI risk. METHODS: Studies presenting relevant evidence for participants aged ≥14 years and living in the UK were eligible for inclusion. A pre-defined search strategy informed by the inclusion criteria was developed. Eleven electronic databases were searched from the start date to September-October 2016. Two researchers independently screened articles, extracted data using a standardised proforma and resolved discrepancies in discussion with a third researcher. Descriptive summaries of evidence are presented. Meta-analyses were not conducted due to variation in study designs. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. RESULTS: Of 3815 abstracts identified, 15 articles reporting quantitative data were eligible and included in the review. No qualitative studies examining contextual drivers of STI risk among people of BC ethnicity were identified. Compared to the white/WB ethnic group, the greater STI/TV risk among BCs was partially explained by variations in socio-demographic factors, sexual behaviours, and recreational drug use. The prevalence of reporting early sexual debut (<16 years), concurrency, and multiple partners was higher among BC men compared to white/WB men; however, no such differences were observed for women. People of BC ethnicity were more likely to access sexual health services than those of white/WB ethnicity. CONCLUSIONS: Further research is needed to explore other drivers of the sustained higher STI/TV prevalence among people of BC ethnicity. Developing holistic, tailored interventions that address STI risk and target people of BC ethnicity, especially men, could enhance STI prevention.

South African report of first case of chromoblastomycosis caused by Cladosporium (syn Cladophialophora) carrionii infection in a cat with feline immunodeficiency virus and lymphosarcoma.

This report describes a 6-year-old neutered male feline immunodeficiency-positive cat with repeated abdominal and thoracic effusions. The cat was diagnosed with and treated for lymphosarcoma but remission was short-lived and, on re-evaluation, a fungal peritoneal exudate was noted. Cytology of the organisms is described and the culture elucidated Cladosporium carrionii, an important cause of chromoblastomycosis. Treatment with itraconazole was unsuccessful in this case.

Clinical management of chlamydia in general practice: a survey of reported practice.

BACKGROUND: Chlamydia trachomatis is the most common curable sexually transmitted infection (STI) in the UK. Prevalence of the infection in different health care settings has been found to be between 2% and 29% and diagnoses of the infection continue to rise significantly. It is estimated, however, that only 10% of all chlamydial infections are seen and treated in genitourinary medicine (GUM) clinics. Few data exist about the actual practice patterns of primary care providers in the management of chlamydia. The management of patients identified with the infection within this setting warrants attention. AIMS: To determine general practitioners' (GPs') and nurses' reported clinical practice in the management of genital chlamydial infection. To design a needs-based education guideline on the management of chlamydia in rural primary care. DESIGN: An anonymous, confidential, self-administered postal questionnaire was sent to all GPs and cervical cytology practice nurses in 84 practices in Dyfed Powys Health Authority (DPHA) area, Wales, UK. RESULTS: Following two mailings of the survey, responses were obtained from 75/84 practices (response rate 89%). A total of 130/307 GPs (response rate 42%) and 72/152 nurses (response rate 47%) in these practices responded. The data demonstrated that few tests for chlamydia are being carried out in general practice: 42% (55/130) of GPs and 54% (37/72) of nurses reported carrying out between one and four tests a month, and 35% (46/130) of GPs and 29% (21/72) of nurses reported performing less than one test a month. Very few positive results are being obtained. The majority of GPs (72%) and nurses (68%) routinely use the appropriate endocervical swab when testing for chlamydia, however 19% of GPs and 20% of nurses are using either an incorrect wooden-stemmed swab or are taking an inappropriate high vaginal swab. CONCLUSIONS: Few chlamydia tests are being performed in primary care in DPHA, Wales. Health professionals in general practice are in need of, and are in favour of, up-to-date training on all aspects of chlamydial identification and management in primary care. Attention needs to be focused upon resources and the paucity of GUM services and their access within the DPHA area.

'Always between two cultures': young British Bangladeshis and their mothers' views on sex and relationships.

This paper presents data on the sexual health perspectives of young British Bangladeshis and their mothers. It discusses the implications of these data for the development of appropriate sexual health education. Between April and September 2006, 36 young people and 25 mothers of Bangladeshi young people were interviewed through seven focus group discussions. Groups were gender and age specific (16-18 years, 19-20 years and mothers). Recruitment took place in community-based organisations in an inner city London borough. Mothers expressed concern about pre-marital sex but felt unable to control out-of-home activity. Feelings of isolation, lack of control and communication difficulties were key issues for them. Young people had varied perspectives on pre-marital sex. Some experienced emotional conflict between what was expected of them in terms of their faith and their engagement in intimate relationships. Both the young people and mothers highlighted the need for sex and relationship education to take account of cultural perspectives and the involvement of parents and the wider community. However, parents and community representatives require information and communication support to enable this involvement. Sex and relationships education content needs to be inclusive, have both secular and faith perspectives and engage where relevant with local communities.

Pragmatic abilities in adults with and without dyslexia: a pilot study.

This study examines well-compensated adults with dyslexia to see if they experience more problems with pragmatic awareness than the normal population. Social interaction requires an individual to process language at speed by using working memory efficiently, in order to understand the intended, rather than literal, meaning between speaker and hearer. Previous studies have shown evidence amongst the dyslexic population of poor working memory capacity, slower speed of processing and automatization deficit. It is proposed that a dyslexic may not be able to interpret pragmatic content as efficiently as non-dyslexics, due to the need for fast processing in such circumstances, resulting in resource overload and over-intensity of memory. The study compares the score results of 20 dyslexic and 20 non-dyslexic adults on the Dyslexia Adult Screening Test (DAST), the Right Hemisphere Language Battery and the author's own pragmatic competence questionnaire. The results for all three measures indicate a statistically significant difference in pragmatic competence between the two groups and appear to demonstrate a correlation between dyslexia and pragmatic impairment. Consideration of individual subtest items on the DAST lend support to the argument that this may be due to deficits in working memory, processing and automatization.
