RESUMO

INTRODUCTION: This study investigated substance use and help-seeking among justice-involved young people to inform and improve service provision during and after contact with the justice system. METHODS: Young people (14-17 years) in the community with current or prior contact with the justice system were recruited in Queensland and Western Australia, Australia using purposive sampling between 2016 and 2018. A cross-sectional survey was delivered by computer-assisted telephone interview. Information was collected on sociodemographic and health factors; lifetime and frequency of use of alcohol, tobacco and other drugs; and use of health services related to substance use and mental health. RESULTS: Of the 465 justice-involved young people surveyed, most had used alcohol (89%), tobacco (86%) or other drugs (81%). Of the latter, cannabis use was most prevalent (79%), followed by ecstasy (26%) and amphetamine (22%). Young people engaging in higher risk drug use (daily use, injecting use) were more likely to also have an alcohol use disorder, be disengaged from education, unemployed, have attempted suicide and experienced incarceration. Of the cohort, 24% had received treatment at an alcohol and drug service in the past year and 30% had seen a health professional about emotional/behavioural problems. Males and Aboriginal and Torres Strait Islander young people were less likely to have sought professional help. CONCLUSION: The high levels of substance use and disproportionate levels of help-seeking observed in this study illustrate the importance of delivering tailored, comprehensive and coordinated trauma-informed and culturally safe alcohol and drug services to justice-involved young people.

RESUMO

OBJECTIVES: To overcome key knowledge gaps in relation to justice involved and vulnerable young people and their sexual health and to compare this group with their peers from other youth health surveys in Australia to determine the extent of the issues. METHODS: Young people, aged between 14 and 17 years, who had ever been or were currently involved with the criminal justice system were purposively sampled. The survey was anonymous and delivered using Computer Assisted Telephone Interview (CATI). RESULTS: A total of 465 justice involved MeH-JOSH young people, aged between 14 and 17 years, participated in the study: 44% Aboriginal and/or Torres Strait Islander (Indigenous) and 37% not attending school. Of the total valid responses, 76% (n = 348) reported having ever had sex, with sexual initiation at a median age of 14 years. We compared these data with their peers in other Australian surveys and found that young people in our study had a higher engagement in sex and start having sex at a younger age, reporting more sexual partners at all ages. CONCLUSIONS: The sexual behaviours of young people involved in the justice system in this study suggest they may be at a greater risk for sexually transmissible infections than their age-matched peers in the general population. Policymakers should elevate them to a priority population for targeting sexual health services and health promotion.

RESUMO

TITLE: Brevetabilité d'un anticorps - Évolution des règles et des pratiques et perspectives. ABSTRACT: Les anticorps monoclonaux représentent aujourd'hui la classe médicamenteuse la plus importante en termes de ventes mondiales. L'obtention d'une protection par brevet de ces molécules est donc cruciale. Une dynamique active de dépôts de demandes de brevets pour protéger les inventions que ces molécules représentent existe donc autant dans l'industrie que dans le monde de la recherche académique. Cependant, les demandeurs doivent faire face à des difficultés récurrentes pour obtenir des brevets de portée importante et faire valoir leurs droits devant les tribunaux. Les trois critères les plus débattus autour des revendications d'anticorps sont : la suffisance/clarté de l'invention, la nouveauté et l'activité inventive. L'objectif de cet article est donc de faire un état des lieux de la pratique en la matière.

RESUMO

Acoustic surveys of bats are one of the techniques most commonly used by ecological practitioners. The results are used in Ecological Impact Assessments to assess the likely impacts of future developments on species that are widely protected in law, and to monitor developments' postconstruction. However, there is no standardized methodology for analyzing or interpreting these data, which can make the assessment of the ecological value of a site very subjective. Comparisons of sites and projects are therefore difficult for ecologists and decision-makers, for example, when trying to identify the best location for a new road based on relative bat activity levels along alternative routes. Here, we present a new web-based, data-driven tool, Ecobat, which addresses the need for a more robust way of interpreting ecological data. Ecobat offers users an easy, standardized, and objective method for analyzing bat activity data. It allows ecological practitioners to compare bat activity data at regional and national scales and to generate a numerical indicator of the relative importance of a night's worth of bat activity. The tool is free and open-source; because the underlying algorithms are already developed, it could easily be expanded to new geographical regions and species. Data donation is required to ensure the robustness of the analyses; we use a positive feedback mechanism to encourage ecological practitioners to share data by providing in return high quality, contextualized data analysis, and graphical visualizations for direct use in ecological reports.

RESUMO

OBJECTIVE: This study investigated immersive virtual reality (IVR), as a novel technique to test executive function of healthy younger and older adults. We predicted IVR tasks to have greater predictive power than traditional measures when assessing age-related cognitive functioning due to the real-world validity of the tasks. METHODS: Participants (n=40) completed the Stroop colour-word test and the trail-making test (TMT) as traditional and commonly used assessments of executive functioning. Participants then completed three IVR tasks; a seating arrangement task, an item location task (both set in a virtual chemistry lab), and a virtual parking simulator. RESULTS: Younger adults completed significantly more parking simulator levels (p<0.001), placed significantly more objects (p<0.001), and located significantly more items than older adults (p<0.01), demonstrating higher levels of performance. Significant correlations were found between performance on traditional neuropsychological measures and IVR measures. For example, Stroop CW performance significantly correlated with the number of parking simulator levels completed (τ=0.43, p<0.01). This suggests that IVR measures assess the same underlying cognitive constructs as traditional tasks. In addition, IVR measures contributed a significant percentage of the explained variance in age. CONCLUSION: IVR measures (i.e. number of parking simulator levels completed and number of objects placed in the seating arrangement task) were found to be stronger contributors than existing traditional neuropsychological tasks in predicting age-related cognitive decline. Future research should investigate the implementation of these real-world-based tasks in clinical groups given this promising initial work.

RESUMO

OBJECTIVE: The objective of this article is to highlight the pitfalls of translating historical cases of wartime psychiatric trauma into modern post-traumatic stress disorder (PTSD). METHOD: We examined all available primary sources relating to the case of Martin O'Meara VC (1885-1935). RESULTS: We found that O'Meara's symptoms are not consistent with a diagnosis of PTSD. CONCLUSIONS: It is more likely that O'Meara developed a form of schizoaffective disorder, or long-lasting trauma-induced psychosis, after World War I.

RESUMO

OBJECTIVE: Assessment of Aboriginal social and emotional wellbeing (SEWB) is a complex and challenging task, in part due to a lack of suitable assessment tools. This paper reports the development and evaluation of a culturally appropriate screening tool called the Here and Now Aboriginal Assessment (HANAA). METHOD: The initial phase included development of a glossary of Aboriginal terms and concepts relating to SEWB. The glossary was used to identify 10 key HANAA domains, which included physical health, sleep, mood, suicide risk and self harm, substance use, memory, unusual experiences, functioning, life stressors and resilience. Evaluation of the HANAA included exploration of its cultural applicability, feasibility, reliability and validity. RESULTS: The HANAA was well accepted by study participants and easily implemented by assessors. Reliability was good, with inter-rater agreements between Aboriginal and non-Aboriginal assessors measured by Kappa statistics ranging from 0.5 to 1.0. There was also a good agreement between assessors and treating clinicians in identifying the main presenting problem and recommended course of action. CONCLUSION: The HANAA is a culturally appropriate and useful tool for the screening of SEWB among Aboriginal adults. It can also be used for teaching and training purposes of mental health and other professionals working with Aboriginal people.

RESUMO

BACKGROUND: Prison suicide rates are high, and suicide-related behaviors (SRBs) higher, but effects of contact with such behaviors in prison have not previously been examined. AIMS: To compare the mental state of young men witnessing a peer's suicide-related behavior in prison with that of men without such experience, and to test for factors associated with morbidity. METHOD: Forty-six male prisoners (age 16-21 years) reporting contact with another's suicide-related behavior in prison were interviewed 6 months after the incident, with validated questionnaires, as were 44 without such contact at least 6 months into their imprisonment. RESULTS: Significantly higher levels of psychiatric morbidity and own suicide-related behaviors were found in the witness group, even after controlling for their higher levels of family mental illness and pre-exposure experience of in-prison bullying. Some personal factors were associated with higher morbidity; incident and institutional factors were not. CONCLUSIONS: Findings of heightened vulnerabilities among young men exposed to suicide-related behaviors in prison suggest a need for longitudinal study to clarify temporal relationships and inform strategies to prevent or limit development of morbidity and further harm.

RESUMO

OBJECTIVES: To explore how Western Australian mental health clinicians want to evaluate their care. METHODS; Using a participatory action research framework, 10 senior psychiatrists and 11 clinical nurse specialists working in an inpatient mental health setting participated in individual interviews, focus groups and meetings. All interviews were de-identified during transcription and transcripts and field notes were analysed for common themes. RESULTS: Participants identified what they wanted to measure, how they wanted to measure it and how these changes could be implemented. Clinicians stressed the importance of measuring context (physical, clinical and service) and process as well as outcome, and of evaluating care at an individual and service level with consumer involvement. What is known about the topic? Completion rates of mandatory national outcome measures in mental health in Australia are variable and clinicians have mixed views as to their value. Several barriers have been identified as to their use including clinical, resource and ownership issues. What does this paper add? Some studies have identified areas of good practice and elicited practical suggestions for improvement but few have asked clinicians how they actually want to evaluate the care they provide. This study explored how mental health clinicians wanted to evaluate their care, using a participatory action research framework that encouraged participants to pinpoint problems and issues, account for their social context and develop actions to address them. What are the implications for practitioners? Clinicians were enthusiastic for high quality care and evaluation, but pessimistic about their ability to introduce sustainable change. Establishing and supporting active and responsible leadership at service level may solve this, as may encouraging local standard setting and benchmarking in collaboration with consumers and carers.

RESUMO

PURPOSE OF REVIEW: There is a well established association between personality disorder and offending but the nature of the relationship is less well understood. We reviewed the recent literature on personality disorder and offending, picking out studies that examined the relationship between the two. RECENT FINDINGS: Cluster A, B and C personality disorders are each associated with different types of offences. Although rates of personality disorder are high in all serious offenders, the role played by personality disorder may be greater in some offences than others, for example, in rapists compared with child molesters, men who kill their fathers rather than their mothers, men who kill their children compared with mothers who kill their children; and in less severe stalking behaviour compared with those who get convictions. Three articles suggested frameworks for understanding how personality disorder may interact with other factors to contribute to offending. SUMMARY: Frameworks that integrate personality traits; comorbid problems such as substance misuse, mood disorders and attention deficit hyperactivity disorder (ADHD) symptoms; motivation for offending; maladaptive cognitions; beliefs and attitudes; anger and arousal; and situational factors are helpful when considering risk assessment, risk management and treatment. More empirical research is needed to test these theories.

RESUMO

LPXTG proteins, present in most if not all Gram-positive bacteria, are known to be anchored by sortases to the bacterial peptidoglycan. More than one sortase gene is often encoded in a bacterial species, and each sortase is supposed to specifically anchor given LPXTG proteins, depending of the sequence of the C-terminal cell wall sorting signal (cwss), bearing an LPXTG motif or another recognition sequence. B. anthracis possesses three sortase genes. B. anthracis sortase deleted mutant strains are not affected in their virulence. To determine the sortase repertoires, we developed a genetic screen using the property of the gamma phage to lyse bacteria only when its receptor, GamR, an LPXTG protein, is exposed at the surface. We identified 10 proteins that contain a cell wall sorting signal and are covalently anchored to the peptidoglycan. Some chimeric proteins yielded phage lysis in all sortase mutant strains, suggesting that cwss proteins remained surface accessible in absence of their anchoring sortase, probably as a consequence of membrane localization of yet uncleaved precursor proteins. For definite assignment of the sortase repertoires, we consequently relied on a complementary test, using a biochemical approach, namely immunoblot experiments. The sortase anchoring nine of these proteins has thus been determined. The absence of virulence defect of the sortase mutants could be a consequence of the membrane localization of the cwss proteins.

RESUMO

The Bacillus cereus group of bacteria is a group of closely related species that are of medical and economic relevance, including B. anthracis, B. cereus, and B. thuringiensis. Bacteria from the Bacillus cereus group encode three large, highly conserved genes of unknown function (named crdA, crdB, and crdC) that are composed of 16 to 35 copies of a repeated domain of 132 amino acids at the protein level. Bioinformatic analysis revealed that there is a phylogenetic bias in the genomic distribution of these genes and that strains harboring all three large genes mainly belong to cluster III of the B. cereus group phylogenetic tree. The evolutionary history of the three large genes implicates gain, loss, duplication, internal deletion, and lateral transfer. Furthermore, we show that the transcription of previously identified antisense open reading frames in crdB is simultaneously regulated with its host gene throughout the life cycle in vitro, with the highest expression being at the onset of sporulation. In B. anthracis, different combinations of double- and triple-knockout mutants of the three large genes displayed slower and less efficient sporulation processes than the parental strain. Altogether, the functional studies suggest an involvement of these three large genes in the sporulation process.

RESUMO

Bacterial surface proteins are key players in host-symbiont or host-pathogen interactions. How these proteins are targeted and displayed at the cell surface are challenging issues of both fundamental and clinical relevance. While surface proteins of Gram-negative bacteria are assembled in the outer membrane, Gram-positive bacteria predominantly utilize their thick cell wall as a platform to anchor their surface proteins. This surface display involves both covalent and noncovalent interactions with either the peptidoglycan or secondary wall polymers such as teichoic acid or lipoteichoic acid. This review focuses on the role of enzymes that covalently link surface proteins to the peptidoglycan, the well-known sortases in Gram-positive bacteria, and the recently characterized l,d-transpeptidases in Gram-negative bacteria.

RESUMO

BACKGROUND: Detention in high security hospitals tends to last several years during patients' early adulthood, yet romantic partnerships and sexuality have been little studied. AIMS: To study such relationships among these inpatients. METHOD: Patients were engaged in a confidential, purpose-designed semi-structured interview concerning their relationships and their views on those of others. RESULTS: Seven (of 10) women and 18 (of 24) men gave interviews. All but one had previously been sexually active. No previous relationship lasted into high security but half (15) reported a new relationship. Most emphasized the importance of caring in respect of sexual activity but sexual intimacy short of intercourse was reported. Most (17) could describe 'safe sex' practices, but few (5) had ever followed them. At least half had experienced seriously abusive sexual relationships in childhood. CONCLUSIONS: Patients appeared able to talk reliably about their romantic and sexual relationships, their interest in which did not cease on incarceration. Findings suggest that it is important for staff to have accurate information on these to ensure safety and adequate support.

RESUMO

Bacillus anthracis, a gram-positive, spore-forming bacterium, is the etiological agent of anthrax. It belongs to the Bacillus cereus group, which also contains Bacillus cereus and Bacillus thuringiensis. Most B. anthracis strains are sensitive to phage gamma, but most B. cereus and B. thuringiensis strains are resistant to the lytic action of phage gamma. Here, we report the identification of a protein involved in the bacterial receptor for the gamma phage, which we term GamR (Gamma phage receptor). It is an LPXTG protein (BA3367, BAS3121) and is anchored by the sortase A. A B. anthracis sortase A mutant is not as sensitive as the parental strain nor as the sortase B and sortase C mutants, whereas the GamR mutant is resistant to the lytic action of the phage. Electron microscopy reveals the binding of the phage to the surface of the parental strain and its absence from the GamR mutant. Spontaneous B. anthracis mutants resistant to the phage harbor mutations in the gene encoding the GamR protein. A B. cereus strain that is sensitive to the phage possesses a protein similar (89% identity) to GamR. B. thuringiensis 97-27, a strain which, by sequence analysis, is predicted to harbor a GamR-like protein, is resistant to the phage but nevertheless displays phage binding.
