Comparison of healthcare quality for uninsured and underinsured children through community health centres in Canada and the USA: a scoping review protocol.

INTRODUCTION: Children and youth who are uninsured or underinsured in Canada and the USA have limited options where they can receive healthcare. In both countries, community health centres (CHCs) have been established as a solution to provide quality care to children without adequate insurance, including those who are newcomers or refugees. However, little is known about how well these models deliver paediatric care. Cross-country analysis provides an important viewpoint to identify areas of success and growth. The purpose of this scoping review is to compare quality of care for uninsured and underinsured children through CHCs in the USA and Canada. METHODS: This scoping review follows the methodological guidelines from the Joanna Briggs Institute Evidence synthesis. The protocol has been registered with the Open Science Framework Registries and can be accessed online. A search will be conducted in electronic databases of peer-reviewed literature (Ovid MEDLINE ALL, CINAHL Complete via EbscoHost, Scopus; Health Business Elite via EbscoHost and Sociological Abstracts via ProQuest) as well as the grey literature. Two reviewers will review all titles and abstracts for inclusion in full-text review. Studies that meet inclusion criteria will be included in full-text review. Data will be extracted into Covidence, using the Donabedian model as a conceptual framework. Findings will be synthesised in a narrative format. ETHICS AND DISSEMINATION: As this study only uses publicly available data, ethics approval is not required. Findings will be shared at national and international conferences and published in a peer-reviewed journal. In addition, findings will be prepared into a policy brief or white paper to be shared with relevant policy stakeholders to advocate for a better model of care for marginalised children and youth.

A Systematic Review of Pharmacological Treatments for Internet Gaming Disorder.

OBJECTIVE: Internet gaming disorder (IGD) is an increasingly common behavioral addiction, with an estimated global prevalence of 3%. A variety of pharmacological treatments have been used to treat IGD, yet no review to date has synthesized clinical trials evaluating their efficacy. This systematic review therefore synthesized the literature reporting on clinical trials of pharmacological treatments for IGD. METHODS: We reviewed articles from MEDLINE, Embase, PubMed Central, CINAHL, and PsycINFO that were published as of March of 2022. A total of 828 articles were retrieved for review and 12 articles were included, reporting on a total of 724 participants. RESULTS: Most participants were male (98.6%), and all were currently living in South Korea. The most common drugs used to treat IGD were bupropion, methylphenidate, and a range of selective serotonin reuptake inhibitors. The Young Internet Addiction Scale was the most frequently used to measure gaming-related outcomes. All studies reported reduced symptoms of IGD from pre- to post-treatment. Across all clinical trials, IGD symptom reductions following the administration of pharmacological treatments ranged from 15.4% to 51.4%. A risk of bias assessment indicated that only four studies had a low risk of bias. CONCLUSION: Preliminary results suggest that a wide array of pharmacological interventions may be efficacious in the treatment of IGD. Future studies using double-blind randomized controlled trial designs, recruiting larger and more representative samples, and controlling for psychiatric comorbidities are needed to better inform understanding of pharmacological treatments for IGD.

Who makes in-play bets? Investigating the demographics, psychological characteristics, and gambling-related harms of in-play sports bettors.

Background and aims: Sports betting has increased markedly in recent years, in part due to legislative changes and the introduction of novel forms of sports betting (e.g., in-play betting). Some evidence suggests that in-play betting is more harmful than other types of sports betting (i.e., traditional and single-event). However, existing research on in-play sports betting has been limited in scope. To address this gap, the present study examined the extent to which demographic, psychological, and gambling-related constructs (e.g., harms) are endorsed by in-play sports bettors relative to single-event and traditional sports bettors. Methods: Sports bettors (N = 920) aged 18+ from Ontario, Canada completed an online survey containing self-report measures of demographic, psychological, and gambling-related variables. Participants were classified as either in-play (n = 223), single-event (n = 533), or traditional bettors (n = 164) based on their sports betting engagement. Results: In-play sports bettors reported higher problem gambling severity, endorsed greater gambling-related harms across several domains, and reported greater mental health and substance use difficulties compared to single-event and traditional sports bettors. There were generally no differences between single-event and traditional sports bettors. Discussion: Results provide empirical support for the potential harms associated with in-play sports betting and inform our understanding of who may be at risk for increased harms associated with in-play betting. Conclusions: Findings may be important for the development of public health and responsible gambling initiatives to reduce the potential harms of in-play betting, particularly as many jurisdictions globally move towards legalization of sports betting.

Children's memory "in the wild": examining the temporal organization of free recall from a week-long camp at a local zoo.

Free-recall paradigms have greatly influenced our understanding of memory. The majority of this research involves laboratory-based events (e.g., word lists) that are studied and tested within minutes. This literature shows that adults recall events in a temporally organized way, with successive responses often coming from neighboring list positions (i.e., temporal clustering) and with enhanced memorability of items from the end of a list (i.e., recency). Temporal clustering effects are so robust that temporal organization is described as a fundamental memory property. Yet relatively little is known about the development of this temporal structure across childhood, and even less about children's memory search for real-world events occurring over an extended period. In the present work, children (N = 144; 3 age groups: 4-5-year-olds, 6-7-year-olds, 8-10-year-olds) took part in a 5-day summer camp at a local zoo. The camp involved various dynamic events, including daily animal exhibit visits. On day 5, children were asked to recall all the animals they visited. We found that overall recall performance, in terms of number of animals recalled, improved steadily across childhood. Temporal organization and recency effects showed different developmental patterns. Temporal clustering was evident in the response sequences for all age groups and became progressively stronger across childhood. In contrast, the recency advantage, when characterized as a proportion of total responses, was stable across age groups. Thus, recall dynamics in early childhood parallel that seen in adulthood, with continued development of temporal organization across middle to late childhood.

Emotion dysregulation mediates the relationship between adverse childhood experiences and problematic gaming.

Gaming disorder (i.e., gaming addiction) is a relatively common mental health disorder with a worldwide prevalence rate of 3.05%. In the present research, we examined whether emotion dysregulation mediates the relation between adverse childhood experiences and problematic gaming in two samples of current video game players. The first sample consisted of 1,262 students recruited from five universities across Canada. The second sample comprised 417 community adults residing in Canada. Both samples of participants completed an online survey which included measures of adverse childhood experiences, problematic gaming, and emotion dysregulation. A total of 45.64% (n = 576) in the university sample and 49.76% (n = 205) in the community sample met the threshold for problematic gaming. In the student sample, adverse childhood experiences were positively associated with problematic gaming. In contrast, there was no significant association between adverse childhood experiences and problematic gaming in the community sample. In both samples, adverse childhood experiences were positively associated with emotion dysregulation, and emotion dysregulation was positively associated with problematic gaming. Importantly for the present research, emotion dysregulation mediated the relationship between adverse childhood experiences and problematic gaming in both the university and community sample. Although adverse childhood experiences are distal and static risk factors for problematic gaming, emotion dysregulation is a more proximal and modifiable risk factor. The results suggest that increasing adaptive emotion regulation skills may decrease the risk of problematic gaming among individuals who have experienced an adverse childhood experience.

Substance-induced psychosis and cognitive functioning: A systematic review.

Longitudinal studies of substance-induced psychosis (SIP) suggest that approximately 11-46% of persons will progress to schizophrenia with differential risk of progression depending on the type of substance used. The findings suggest SIP may be a distinct variant of a psychotic disorder, yet SIP is understudied and the disease expression is not well characterized, particularly the cognitive phenotype. There is some evidence for cognitive dysfunction in SIP, but a synthesis of this literature has not been undertaken. We systematically reviewed all empirical research (up to December 31, 2020) that examined cognition in SIP using clinical neuropsychological measures. The cognitive outcomes are summarized by type of SIP (methamphetamine, other stimulants, alcohol, cannabis, undifferentiated). There was evidence for global and domain-specific cognitive dysfunction in SIP compared to controls and non-psychotic persons who use substances. Impairments were of similar magnitude compared to persons with schizophrenia. Delineation of a specific cognitive profile in SIP was precluded by lack of literature with comparable study designs and outcomes. Variation in visual-based cognition may be a distinct feature of SIP, but this requires further investigation. More rigorously controlled studies of cognition in SIP are needed to inform differential diagnosis and identify the unique clinical needs of this population.

Tell Me About Your Visit With the Lions: Eliciting Event Narratives to Examine Children's Memory and Learning During Summer Camp at a Local Zoo.

School-aged children often participate in school field trips, summer camps or visits at informal learning institutions like zoos and museums. However, relatively little is known about children's memory and learning from these experiences, what types of event details and facts are retained, how retention varies across age, and whether different patterns are observed for different types of experiences. We aimed to answer these questions through a partnership with a local zoo. Four- to 10-year-old children (N = 122) participated in a weeklong summer camp, during which they engaged in dynamic events, including visits to zoo animals. On the last day of camp, we elicited autobiographical event narratives for two types of experiences: a child-selected animal event (visit to their favorite animal) and an experimenter-selected animal event. We coded event narratives for length and breadth using previously used autobiographical memory (AM) narrative coding schemes. In addition, we created a coding scheme to examine retention of semantic information (facts). We report the types of autobiographical event details and facts children recalled in their narratives, as well as age group differences that were found to vary depending on the type of information and type of event. Through this naturalistic, yet controlled, study we gain insights into how children remember and learn through hands-on activities and exploration in this engaging and dynamic environment. We discuss how our results provide novel information that can be used by informal learning institutions to promote children's memory and retention of science facts.

The Effect of Compositional Changes Due to Seasonal Variation on Milk Density and the Determination of Season-Based Density Conversion Factors for Use in the Dairy Industry.

The objective of this study was to determine the effect of seasonal variation on milk composition and establish an algorithm to predict density based on milk composition to enable the calculation of season-based density conversion calculations. A total of 1035 raw whole milk samples were collected from morning and evening milking of 60 spring-calving individual cows of different genetic groups, namely Jersey, Elite HF (Holstein-Friesian) and National Average HF, once every two weeks for a period of 9 months (March-November, 2018). The average mean and standard deviation for milk compositional traits were 4.72 ± 1.30% fat, 3.85 ± 0.61% protein and 4.69 ± 0.30% lactose and density was estimated at 1.0308 ± 0.002 g/cm3. The density of the milk samples was evaluated using three methods: a portable density meter, DMA 35; a standard desktop version, DMA 4500M; and an Association of Official Agricultural Chemists (AOAC) method using 100-mL glass pycnometers. Statistical analysis using a linear mixed model showed a significant difference in density of milk samples (p < 0.05) across seasonal and compositional variations adjusted for the effects of days in milk, parity, the feeding treatment, the genetic group and the measurement technique. The mean density values and standard error of mean estimated for milk samples in each season, i.e., spring, summer and autumn were 1.0304 ± 0.00008 g/cm3, 1.0314 ± 0.00005 g/cm3 and 1.0309 ± 0.00007 g/cm3, respectively.
