Homelessness and housing stress among police detainees: results from the DUMA program

This research reaffirms the need for intensive accommodation support services to complement criminal justice responses to crime and those who have contact with the criminal justice system. Foreword It is generally accepted that a person’s living situation, in particular their experience of homelessness and housing stress, can have both long-lasting and wide-ranging consequences. For criminal justice practitioners, the task of limiting homelessness and preventing crime remain key policy priorities in need of ongoing and integrated research. This paper provides a much needed examination of homelessness and housing stress among Australia’s criminal justice population. Using data from the AIC’s Drug Use Monitoring in Australia program, this study examines the prevalence and nature of homelessness among a sample of police detainees. It is the first of its kind to examine a broader range of homelessness experiences and the reasons why some offenders have few choices but to ‘sleep rough’ or seek accommodation support. Importantly, the authors estimate that 22 percent of the detainee population is homeless or experiencing housing stress in some form; much higher than has been previously estimated. This research reaffirms the need for intensive accommodation support services to complement criminal justice responses to crime and those who have contact with the criminal justice system

The relationship between online gaming and wellbeing among post-secondary students

As the “fastest growing form of entertainment in the world” (Tran, 2019, p. 76), gaming has become a significant part of our society (Groening & Binnewies, 2019). Considering its widespread popularity as a leisure activity amongst adolescents and adults (Entertainment Software Association of Canada, 2020), it is unsurprising that multiple studies have explored its relationship to the player’s wellbeing. Previous research has found mixed findings regarding gaming’s impact on wellbeing. Several findings have identified gaming as a way to relieve stress, relax (Russoniello et al., 2009; Snodgrass et al., 2011; Wack & Tantleff-Dunn, 2009), positively influence aspects of social wellbeing (Gitter et al., 2013; Kowert & Oldmeadow, 2015; Martončik & Lokša, 2016) and is associated with a variety of improvements in psychological and physiological functions (Ryan et al., 2006). Despite these benefits, numerous other findings have associated gaming with negative outcomes such as interfering with a player’s social functioning, wellbeing, and adjustment (Grüsser et al., 2007; Stockdale & Coyne, 2018; Weinstein, 2010). Given these apparent contradictions in previous literature, further exploration needs to be conducted in understanding the relationship of gaming and wellbeing among post-secondary students. To examine this relationship, additional factors that can impact one’s wellbeing should be considered such as the motives for engaging in their leisure pursuits, one’s feelings of connection and support from others in the community, and the breadth of activities one engages in. The purpose of this study was to explore the relationship between gaming and wellbeing among post-secondary students while taking into account the player’s motivation, social connectedness, and overall leisure repertoire. A secondary data analysis was undertaken using data (n = 982) gathered from the Georgian College Student Wellbeing Survey launched in January 2019 conducted by the Canadian Index of Wellbeing (CIW). Multiple factors were considered in exploring the relationship to wellbeing including the students demographic characteristics (age, sex, student status). Students identified the frequency and intensity of their gaming, a measure of their leisure repertoire was calculated, and the degree to which they were socially motivated to participate in their leisure assessed. Three different measures were used to assess social connectedness: (1) number of close friends, (2) feelings of social isolation, and (3) sense of community (i.e., social climate and bonds). Finally, as a measure of their subjective wellbeing, students rated their life satisfaction along an 11-point scale. The findings indicated that neither whether students participated in gaming nor their intensity of gaming were significant factors in explaining wellbeing. Instead, social factors (feelings of social isolation and perceptions of social climate and bonds) and leisure repertoire were particularly significant factors in explaining their wellbeing. Reducing feelings of social isolation emerged as the most important factor in explaining wellbeing irrespective of how intensely or how often students participate in gaming. Ultimately, social context is the most important factor in explaining variations in wellbeing, above and beyond other factors including gaming participation and intensity

Exploring stop signal reaction time over two sessions of the anticipatory response inhibition task

Various behavioural tasks measure response inhibition encompassing the ability to cancel unwanted actions, evaluated via stop signal reaction time (SSRT). It is unclear whether SSRT is an unchangeable inherent measure of inhibitory network integrity or whether it can improve with repetition. The current study explored if and how SSRT changed over two sessions for the Anticipatory Response Inhibition Task (ARIT), and how this compared with the Stop Signal Task (SST). Forty-four participants repeated the ARIT and SST over two sessions. SSRT and its constituent measures (Go trial reaction time, stop signal delay) were calculated. SSRT reflecting non-selective response inhibition was consistent between sessions in the ARIT and SST (both p > 0.293). Reaction time and stop signal delay also remained stable across sessions in the ARIT (all p > 0.063), whereas in the SST, reaction time (p = 0.013) and stop signal delay (p = 0.009) increased. SSRT reflecting behaviourally selective stopping on the ARIT improved (p < 0.001) over two sessions, which was underpinned by changes to reaction time (p < 0.001) and stop signal delay (p < 0.001). Overall, the maximal efficiency of non-selective inhibition remained stable across two sessions in the ARIT. Results of the SST confirmed that non-selective inhibition can, however, be affected by more than inhibitory network integrity. Behaviourally selective stopping on the ARIT changed across sessions, suggesting the sequential neural process captured by the SSRT occurred more quickly in session two. These findings have implications for future studies that necessitate behavioural measures over multiple sessions.publishedVersio

Utilization of Waist Circumference to Determine Type 2 Diabetes Risk Among Normal and Overweight Individuals

The purpose of this study is to investigate whether noninvasive measurements such as waist circumference (WC) and waist-to-hip ratio (WHR) are effective for people who have a normal to overweight BMI in determining risk for type 2 diabetes. 29 million US adults have diabetes and 86 million have prediabetes. Numerous studies have indicated waist circumference as a strong predictor of type 2 diabetes in obese individuals. However there are few that research the effects of these anthropometric measurements with individuals who look lean but are potentially metabolically obese

Traumatic brain injuries and problem gambling in youth: Evidence from a population-based study of secondary students in Ontario, Canada

Traumatic brain injury (TBI) is characterized by a change in brain function after an external force or sudden movement to the head. TBI is associated with risk-taking, impulsivity, psychological distress, substance abuse, and violent crime. Previous studies have also linked problem gambling to TBI, but these studies have not controlled for possible confounding variables such as mental health problems and hazardous drinking which are also linked to TBI. This study examines the relationship between problem gambling and TBI among adolescents. Data were obtained from the 2011, 2013 and 2015 cycles of the OSDUHS, a biennial cross-sectional school-based study of children in grades 7 to 12 (N = 9,198). Logistic regression was used to estimate adjusted odds ratios (AOR) in controlled and uncontrolled analyses. Adjusting for sex and grade only, problem gambling was associated with a history of TBI (AOR = 2.8). This association remained significant after adjusting for hazardous drinking and suicidality (AOR = 2.0). In addition, problem gambling had a statistically significant relationship with being male (AOR = 4.7), hazardous drinking (AOR = 4.5), and suicidality (AOR = 3.1). This study provides further data to suggest a link between TBI and problem gambling. However, research is needed on the causal relationship between these variables and the potential implications for treatment and prevention

Improved respiratory motion tracking through a novel fiducial marker placement guidance system during electromagnetic navigational bronchoscopy (ENB)

Background: Stereotactic ablative radiotherapy (SABR) is a treatment option for patients with early stage non-small cell lung cancer (NSCLC) and recurrent or oligometastatic disease who are not surgical candidates. Due to the continuous motion of tumors within the lungs, implementing a strategy to track the target lesion is crucial. One method is to place fiducial markers which the robotic SABR system is able to track during treatment. However, placing these markers in a manner that maximizes tracking efficacy can be challenging. Using a novel fiducial placement guidance system (FPGS) during fiducial deployment may offer a way to improve the quantity of fiducials tracked by the robotic SABR system. Method: This was an institutional, retrospective review identifying all patients who received robotic SABR for lung tumors from May 2015 until January 2017. The FPGS was instituted in May 2016. The median number of fiducials tracked and the rate of complication was compared between patients whose fiducials were placed using FPGS versus those that were not. Results: A total of 128 patients with 147 treated lung lesions were identified. Of the lesions that utilized FPGS (n = 44), 28 had 2 tracked fiducials (63.6%), 14 had 3 (31.8%) and 2 had 4 (4.6%). Of the lesions treated without FPGS (n = 103), 5 had 1 tracked fiducial (4.9%), 91 had 2 (88.4%), 6 had 3 (5.8%), and 2 had 4 (1.9%). A significant improvement in the median number of fiducials tracked per fraction was observed for the lesions with fiducials placed using FPGS on Wilcoxon rank sum test (p < 0.001). The rate of complication was low and not statistically different between cohorts (p = 0.44). Conclusions: The FPGS can be used during the deployment of fiducial markers and may increase the number of fiducials tracked

Possible Seasonality of Clostridium difficile in Retail Meat, Canada

We previously reported Clostridium difficile in 20% of retail meat in Canada, which raised concerns about potential foodborne transmissibility. Here, we studied the genetic diversity of C. difficile in retail meats, using a broad Canadian sampling infrastructure and 3 culture methods. We found 6.1% prevalence and indications of possible seasonality (highest prevalence in winter)

Environmental DNA metabarcoding provides enhanced detection of the European eel Anguilla anguilla and fish community structure in pumped river catchments

© 2020 Fisheries Society of the British Isles The European eel Anguilla anguilla (eel hereafter) is critically endangered and has a catadromous life cycle, which means adult eels that live in pumped catchments must pass through pumps during their downstream spawning migration. Policy makers are currently lacking detailed site-by-site eel distribution information to estimate the overall impact of individual pumping stations on eel escapement, and as such lack the data to enable informed prioritisation of pumping station management and targeted mitigation. This study investigated whether environmental DNA (eDNA) metabarcoding can provide increased detection sensitivity for eel and fish community structure in highly regulated pumped catchments, when compared directly to current standard practice fish survey protocols (seine netting/electric fishing). Eels were detected in 14 of 17 sites (82.4%) using eDNA metabarcoding in contrast to 3 of 17 sites (17.6%) using traditional catch methods. In addition, when using eDNA monitoring, species richness was higher in 16 of 17 sites (94.1%), and site occupancy was greater than or equal to traditional methods for 23 of 26 of the fish species detected (88.5%). Although eDNA methods presented significantly higher average species richness and species site occupancy overall, eDNA and catch methods were positively correlated in terms of species richness and site occupancy. It was therefore found that eDNA metabarcoding was a high-sensitivity method for detecting eels in pumped catchments while also increasing the detection of overall fish community structure compared to traditional catch methods. In addition, this study highlights how eDNA monitoring is especially suited to increase the detection of particular species, with traditional methods sufficient for others. This high sensitivity, coupled with the ability to sample multiple sites in a short time frame, suggests that eDNA metabarcoding workflows could be invaluable tools when prioritising pumping station management

Moderate to severe gambling problems and traumatic brain injury: A population-based study

Traumatic brain injury (TBI) is a common injury characterized by a change in brain function after an external blow to the head and is associated with substance abuse, psychological distress, risk-taking, and impulsivity. Convenience and clinical samples have also linked TBI to problem gambling, but have not ruled out confounding variables such as hazardous drinking and psychological distress. This study examines the relationship between TBI and moderate to severe problem gambling in a general population probability sample controlling for hazardous drinking and psychological distress. The data were obtained from a 2015–2016 cross-sectional general population telephone survey of adults ages 18+from Ontario, Canada (N = 3809). Logistic regression was used to estimate the association as adjusted odds ratios (AOR). Moderate to severe problem gambling was independently associated with a history of TBI after adjusting for potential confounders (AOR: 2.80), and had a statistically significant relationship with psychological distress (AOR = 2.74), hazardous drinking (AOR = 2.69), and lower educational levels (AOR = 0.37). This study provides further data to suggest a link between TBI and moderate to severe problem gambling; however, more research is needed to determine if there is a causal relationship or the potential implications for prevention and treatment
