Facial injuries, including maxillofacial trauma (MFT), are common in children and adolescents due to their age and bone maturation stage. Children\'s injuries are less common than adults\' due to parental supervision and the flexibility of the facial bone. Causes of maxillofacial bone fractures (MFBF) vary based on socioeconomic, cultural, and environmental factors. Management of MFBF in children and adolescents should consider their growth and development stage. A systematic review is needed to understand the prevalence, pattern, and distribution of MFBF in Saudi Arabia. This systematic review aimed to identify papers on MFBF in children and adolescents in Saudi Arabia using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. The search strategy involved searching electronic databases like PubMed/Medline, Web of Science, and Ebsco. The review included full-text original research papers, with inclusion criteria including English publications, human studies, and no restrictions on sample size, gender, date, or language. The selection process involved screening titles and abstracts, evaluating full texts, and identifying relevant studies. Data extraction involved two authors individually assessing selected studies. The PRISMA flow diagram of the literature search revealed that 26 papers were identified, of which 15 remained after excluding duplicates. After screening titles and abstracts, 10 articles were removed, and five papers were assessed for eligibility. Four papers met the inclusion criteria for the systematic review. The studies examined 1447 patients for the presence of MFBF in different regions. The majority of MFBF were caused by falls and road traffic accidents (RTAs) in children and adolescents. Mandibular fractures were the most common, followed by maxillary fractures. The majority of patients had tooth/teeth avulsions, followed by tooth luxation and crown fractures. Only one study described investigation methods for MFBF diagnosis. The systematic review reveals a high prevalence of MFBF among children and adolescents in Saudi Arabia, primarily due to falls and RTAs. The mandible is the most frequently fractured bone, and many children have concomitant teeth involvement. To reduce MFBF, effective initiatives and parental awareness strategies are recommended.

BACKGROUND: Canada legalized recreational cannabis in 2018, and one of the primary objectives of the Cannabis Act was to protect youth by reducing their access to cannabis and providing public education. Canada has the highest prevalence of cannabis use worldwide, particularly among youth and young adults under the age of 25. Cannabis use is linked with many adverse effects for youth and young adults including psychosis, anxiety, depression, respiratory distress, cannabinoid hyperemesis syndrome, and impaired cognitive performance. Despite the high prevalence of cannabis use and the evolution of policies in Canada and globally, significant knowledge and research gaps remain regarding youth and young adult cannabis use. The aim of this scoping review is to map the extent, nature, and range of evidence available on youth and young adult cannabis use in Canada since its legalization, in order to strengthen policies, services, treatments, training, and public education strategies.
METHODS: Using a scoping review framework developed by Arksey and O\'Malley, along with the PRISMA-ScR guidelines, we conducted a rigorous search in five academic databases: MEDLINE, Embase, APA PsycINFO, CINAHL and Web of Science Core Collection. We included empirical studies that collected data in Canada after the legalization of recreational cannabis (October 2018) and focused on youth or young adults < 30. Two reviewers independently screened articles in two stages and extracted relevant information from articles meeting the inclusion criteria.
RESULTS: Of the 47 articles meeting our inclusion criteria, 92% used quantitative methods, 6% were qualitative, and 2% used a mixed-methods approach. Over two-thirds (68%) used secondary data. These studies were categorized into six focus areas: (1) prevalence, patterns, and trends, (2) cannabis-related injuries and emergency department (ED) visits, (3) rates and patterns during the pandemic, (4) perceptions of cannabis use, (5) prevention tools, and (6) cannabis-related offenses. Key findings from the studies reviewed include an increase in cannabis use among 18-24-year-olds post-legalization, with mixed results for youth under 18. ED visits for intentional and unintentional cannabis-related injuries have increased in young children and teens. Perception studies show a mix of concern and normalization of cannabis use. Though limited, prevention studies are promising in raising awareness. A decline in cannabis-related offenses was noted by one study. The review highlights several research gaps, including the need for more qualitative data, disaggregation of demographic data, intervention research, and comprehensive studies on the physical and mental health impacts of cannabis use among youth and young adults.
CONCLUSIONS: Maintaining a public health approach is critical, with a focus on reducing the high prevalence of cannabis use among youth and young adults. This involves implementing prevention strategies to minimize harms, enhancing public education, minimizing commercialization, reducing youth access to cannabis, promoting guidelines for lower-risk cannabis use and harm reduction strategies, and increasing training for healthcare providers.

BACKGROUND: Providing menstrual education and guidance for menstrual management for girls and young women with intellectual disabilities is recommended to ensure smooth pubertal transitions and to support menstrual self-agency.
METHODS: The purpose of this systematic review is to explore menstrual education interventions for girls and young women with intellectual disabilities.
RESULTS: Nine studies were included. Interventions were provided in small groups (n = 4) and individually (n = 5). Most studies used dolls (n = 7) and task analysis (n = 7) to teach pad-replacement skills. All reported significant improvements in participant skills and/or knowledge following the intervention. Only one study addressed self-agency and self-esteem as an outcome of the intervention. Menstrual education for girls and young women with intellectual disabilities is largely focused on pad-replacement skills.
CONCLUSIONS: Further research is needed to understand the impact of menstrual health and hygiene education on variables apart from skill improvement such as self-agency and long-term health outcomes related to menstrual health.

Adult obesity has remained a key health concern globally. Theory-based social marketing interventions are considered effective for improving dietary and physical activity (PA) behaviours. However, their application in universities is not yet established. This review aimed to identify social marketing strategies targeting healthy eating and/or PA behaviours of young adult university students and outline the intervention effectiveness. Literature search, screening, and data extraction followed the Joanna Briggs Institute (JBI) methodology for scoping reviews. PubMed/Medline and Scopus databases were searched for intervention and exploratory studies published between January 1, 2000, and September 20, 2023. Twelve articles were selected based on the eligibility criteria. Although different in study design, all studies reported improved healthy eating-related outcomes, while three showed improved PA-related outcomes. One study incorporated all six of the social marketing benchmarks, but the majority identified two. Most studies focused on behavioural objective, formative research, and marketing mix in their intervention design. Four studies incorporated behaviour change theories in development of the social marketing campaigns. Social marketing using social media could be a significant approach for improving healthy eating and PA in young adult university students when behavioural change theories and all social marketing benchmarks are adopted. More generalizable longer-term investigation into the effectiveness of this approach in university young adults is needed to tackle adult obesity related health issues.

BACKGROUND: Polyps are the predominant precursors of colorectal cancer. In the past three decades, the incidence and mortality rates of colorectal cancer have been increasing in adults younger than 50 years.
OBJECTIVE: The aim of this clinical audit was to evaluate the prevalence, characteristics and clinical associations of polyps in adults aged 18-49 years presenting to an established private gastroenterology clinic in the Toowoomba Darling Downs region.
METHODS: The audit included data from 353 patient records held by the Toowoomba Gastroenterology Clinic. Data extracted from patient medical records through the Medical Director program software contained structured endoscopy/colonoscopy and histology reports of excised lesions of patients presenting to the clinic. The extract involved identifying all patients aged 18-49 years in the database from January 2019 to March 2022. Patients were screened based on audit inclusion and exclusion criteria. Patients were risk stratified for recommended surveillance intervals as per Australian Clinical Guidelines.
RESULTS: Of the sample population, 33.4% were identified with polyps and 22.4% were identified with neoplastic polyps (NPs). A total of 6.7% of 18- to 29-year-old patients were identified with intermediate risk for colorectal cancer (CRC) screening, and 19.8% and 19.3% of 30- to 39-year-old and 40- to 49-year-old patients identified with intermediate or high risk for CRC screening respectively. Increased age, greater size of polyps and surveillance of previous polyps were associated with increased NP prevalence.
CONCLUSIONS: Data from this audit supported the temporal trend of increasing prevalence of polyps in adults younger than 50 years. Patient cohorts aged 30-39 and 40-49 years may benefit from earlier first colonoscopies. Findings could be the impetus for future research in young adults presenting for colonoscopy.

Background: As a result of demographic change, chronic and oncological diseases are gaining importance in the context of public health. Palliative care plays a crucial role in maintaining the quality of life of those affected. International guidelines demand access to palliative care not only for the elderly but also for younger people who face severe illnesses. It can be assumed that palliative care will become increasingly important for them. In order to develop public health strategies which are able to promote palliative care, it is important to assess the knowledge of, and attitude towards, palliative care as found among members of the general public and its specific target groups. In particular, little is known about young adults\' knowledge and perceptions of palliative care. Objectives and design: This work aimed to assess the understanding and viewpoints regarding palliative care among the general population and among young adults aged 18 to 24. We therefore conducted a systematic review, which, for this target population, could be seen as a novel approach. Methods: Exclusion and inclusion criteria were developed using the PICOS process. Literature was researched within MEDLINE (via PubMed), Google Scholar and Web of Science. A search string was developed and refined for all three databases. Grey literature was included. Duplicates were excluded using Mendeley. The literature was independently screened by two researchers. Narrative synthesis was used to answer the main research question. Results: For the general public, palliative care is still associated with death and dying and comforting sick people towards the end of their lives. Multiple social determinants are linked to better knowledge of palliative care: higher education, higher income, female gender, having relatives that received palliative care, and permanent employment. The population\'s knowledge of palliative care structures increases, the longer such structures have been established within a country. Young adults are familiar with the term palliative care, yet their understanding lacks nuance. They associate palliative care with death and dying and perceive palliative care to be a medical discipline primarily for the elderly. Nevertheless, young adults demand participation within the planning of interventions to destigmatize palliative care. Conclusions: The general public still lacks a detailed understanding of palliative care. Palliative care faces stigma at multiple levels, which creates barriers for those who set out to implement it. However, addressing young adults as a crucial peer group can help break down barriers and promote access to palliative care.

There is a lack of robust research investigating the association between neurocognitive impairments and chronic tobacco smoking in adolescents/young adults. Therefore, a systematic review and meta-analysis were conducted to examine this association by pooling cross-sectional studies published from 1980 to 2023. The systematic review assessed the neurocognitive performances between chronic tobacco smokers and non-smokers in each study. The meta-analysis included six studies that compared chronic tobacco smokers against non-smokers using neuropsychological tests covering three neurocognitive domains. The results showed a cross-sectional association between impairpments in motor impulsivity across two aspects: reaction delay and incongruent errors, with the effect size being (SDM = 0.615, p = 0.000) and (SDM = 0.593, p = 0.000) respectively. However, no significant associations were found for intelligence (SDM = 0.221, p = 0.425) or working memory (SDM = 0.150, p = 0.581). This study highlights the need for further research to explore a greater number of neurocognitive domains in the context of chronic smoking in adolescents/young adults, particularly motor impulsivity, intelligence and working memory, as well as the socioeconomic factors involved. There is also a need to further study the effects of emerging alternative nicotine administration methods in this age group.

Researchers have examined civic engagement as a health promotion tool among older adults and adolescents, yet less is known about its mental health implications for young adults. This systematic review identified 53 articles on civic engagement and well-being in young adults. Five key themes emerged: (1) varying associations between type of civic engagement and well-being, (2) duration and frequency of civic behaviors, (3) directionality in the civic-to-well-being pathway, (4) mediation and moderation factors affecting the civic-to-well-being pathway, and (5) civic engagement as a tool for coping with adversity or systemic oppression. Civic engagement demonstrates a heterogeneous relationship to well-being; future research should focus on the explanatory pathways for positive, negative, and null correlations particularly among historically marginalized young adults.

UNASSIGNED: A systematic review of the literature was performed to summarize cannabis use among adolescents and young adults during the COVID-19 pandemic. Special focus was given to the prevalence of cannabis use during COVID-19, as well as factors that may explain changes in cannabis consumption patterns.
UNASSIGNED: The protocol of this systematic review was registered. Articles from seven publication databases were searched in January 2022. The inclusion criteria for studies were as follows: 1) published in English; 2) study instruments needed to include items on COVID-19; 3) conducted after January 1st, 2020; 4) published in a peer-reviewed journal, dissertation, or thesis; 5) study population ≤25 years of age; 6) study designs were limited to observational analytical studies; 7) measured cannabis use. This review excluded other reviews, editorials, and conference abstracts that were not available as full text manuscripts. Independent review, risk of bias assessment, and data abstraction were performed by two authors.
UNASSIGNED: Fifteen articles from the United States (n=11) and Canada (n=4) were included in this review. The findings of this review showed that the prevalence of cannabis use during the pandemic among adolescents and young adults were mixed. Some mental health symptoms, including depression and anxiety, were identified as the most commonly reported reasons for increased cannabis use during the pandemic.
UNASSIGNED: This review highlights the inconsistencies in the prevalence of cannabis use among adolescents and young adults during the pandemic. Therapeutic interventions for mental health and continued public health surveillance should be conducted to understand the long-term effects of cannabis use among adolescents and young adults.

BACKGROUND: The high prevalence of cannabis use among young adults poses substantial global health concerns due to the associated acute and long-term health and psychosocial risks. Digital modalities, including websites, digital platforms, and mobile apps, have emerged as promising tools to enhance the accessibility and availability of evidence-based interventions for young adults for cannabis use. However, existing reviews do not consider young adults specifically, combine cannabis-related outcomes with those of many other substances in their meta-analytical results, and do not solely target interventions for cannabis use.
OBJECTIVE: We aimed to evaluate the effectiveness and active ingredients of digital interventions designed specifically for cannabis use among young adults living in the community.
METHODS: We conducted a systematic search of 7 databases for empirical studies published between database inception and February 13, 2023, assessing the following outcomes: cannabis use (frequency, quantity, or both) and cannabis-related negative consequences. The reference lists of included studies were consulted, and forward citation searching was also conducted. We included randomized studies assessing web- or mobile-based interventions that included a comparator or control group. Studies were excluded if they targeted other substance use (eg, alcohol), did not report cannabis use separately as an outcome, did not include young adults (aged 16-35 y), had unpublished data, were delivered via teleconference through mobile phones and computers or in a hospital-based setting, or involved people with mental health disorders or substance use disorders or dependence. Data were independently extracted by 2 reviewers using a pilot-tested extraction form. Authors were contacted to clarify study details and obtain additional data. The characteristics of the included studies, study participants, digital interventions, and their comparators were summarized. Meta-analysis results were combined using a random-effects model and pooled as standardized mean differences.
RESULTS: Of 6606 unique records, 19 (0.29%) were included (n=6710 participants). Half (9/19, 47%) of these articles reported an intervention effect on cannabis use frequency. The digital interventions included in the review were mostly web-based. A total of 184 behavior change techniques were identified across the interventions (range 5-19), and feedback on behavior was the most frequently used (17/19, 89%). Digital interventions for young adults reduced cannabis use frequency at the 3-month follow-up compared to control conditions (including passive and active controls) by -6.79 days of use in the previous month (95% CI -9.59 to -4.00; P<.001).
CONCLUSIONS: Our results indicate the potential of digital interventions to reduce cannabis use in young adults but raise important questions about what optimal exposure dose could be more effective, both in terms of intervention duration and frequency. Further high-quality research is still needed to investigate the effects of digital interventions on cannabis use among young adults.
