RESUMEN

BACKGROUND: Hemp-based psychoactives comprise a burgeoning legal substance market with rising trends in use across the U.S. and Canada as well as parts of Europe. Currently, scant empirical research on the use of these Novel Psychoactive Substances (NPS) exists. By examining policy, market conditions, consumer uptake, and related risks, this research extends theory on drug trends by describing the regulatory environments that shape the emergence and popularity of psychoactive hemp-based products among young adults. METHODS: Relying on ethnographic fieldwork of hemp-based markets across 3 U.S. state hemp and cannabis policy contexts as well as in-depth interviews with 40 young adult cannabis consumers recruited across 10 U.S. states, we examined how regulatory conditions shape hemp-based psychoactive markets, trends in their use, and associated risks. RESULTS: Young adults are motivated to consume hemp-based psychoactives due to the regulatory and market environments that facilitate the production of highly potent products that are inexpensive and easily accessible. States that regulate hemp-based psychoactives as cannabis, do not provide hemp markets with a competitive advantage and as such see minimal uptake. In the absence of hemp specific policies, substantial variations in product potencies, insufficient dosing information, and unscrupulous product packaging practices may increase related risks. CONCLUSION: Trend theory provides insight into the complex relationships that exist between drug policy, markets, and the proliferation of legal highs. Understanding the contextual significance that both market and regulatory conditions have on legal drug production, distribution, and consumption may better inform approaches to reduce the risks commonly associated with novel psychoactive substances like hemp-based psychoactives.

RESUMEN

PURPOSE: To identify risk factors for relaxing a strict e-cigarette ban in households with adolescents. METHODS: Youth (ages 12-17) in the Population Assessment of Tobacco and Health (PATH) Study whose parents held a strict vaping ban in 2016 (n = 6,514; 51.5% male) and their parents provided follow-up data on up to four occasions through 2020 on whether the ban was relaxed. RESULTS: 13.5% of households with strict vaping bans relaxed them in a subsequent wave. Results from a logistic regression model showed that the odds of relaxing strict bans were higher if, at baseline, parents vaped (OR = 2.20; 95% CI: 1.22-3.97; p < .01), parents smoked tobacco (OR = 2.55; CI: 2.00-3.26; p < .001), youth smoked tobacco (OR = 2.27; CI: 1.29-4.00; p < .01), parents reported no smoking ban (OR = 2.68; CI: 1.88-3.81; p < .001), youth did not know that their household had a vaping ban (OR = 1.95; CI: 1.50-2.54; p < .001), and parents perceived low harm from vaping (OR = 1.60; CI: 1.16-2.19; p < .01). Although most sociodemographic controls were not independently associated, parents were less likely to relax bans if they had a college degree (OR = 0.71; CI: 0.51-0.998; p < .05), graduate degree (OR = 0.50; CI: 0.43-0.72; p < .001), or children who were non-Hispanic Black (OR = 0.69; CI: 0.49-0.96; p < .05) or Hispanic (OR = 0.62; CI: 0.47-0.81; p < .001). DISCUSSION: While most households with adolescents prohibited e-cigarette use indoors, nearly one in seven relaxed prior strict vaping bans. Parents need support to maintain clear, consistent, and continuous restrictions that communicate that vaping is not safe or permissible for youth.

RESUMEN

INTRODUCTION: Co-use of tobacco and cannabis has long been an issue for prevention and intervention efforts targeting these substances. Blunt use-cannabis inside a cigar wrapper-has been a consistent mode of cannabis consumption since the 1990s. Since then, both tobacco control and cannabis policies have changed considerably. This paper examines the influence of tobacco taxes and smoke-free policies as well as medical and recreational cannabis policies on blunt use among young people. METHODS: Combining state-level tobacco control and cannabis policy data with the restricted-access youth cohort of the Population Assessment of Tobacco and Health (PATH) study, we use multilevel logistic regression models to examine the impact of these policies on past-year blunt use. RESULTS: While we found a main effect whereby both legal medical and recreational cannabis policies are associated with higher odds of blunt use among youth, interaction effects demonstrate that this association only emerges in states lacking a comprehensive tobacco smoke-free policy. In states with smoke-free policies, we found no significant associations between cannabis policy and odds of blunt use. CONCLUSIONS: Denormalization through smoke-free policies may mitigate the effects of recreational and medical cannabis policies on blunt use. Smoke-free policies represent a possible cost-effective mechanism to curb the co-use of tobacco and cannabis in the form of blunts. States with medical and recreational cannabis policies may benefit from greater prevention efforts for young people specifically focused on blunt use, especially in states that do not have strong tobacco control.

RESUMEN

BACKGROUND: Evidence indicates that communication skills teaching learnt in the classroom are not often readily transferable to the assessment methods that are applied nor to the clinical environment. An observational study was conducted to objectively evaluate students' communication skills in different learning environments. The study sought to investigate the extent to which the communication skills demonstrated by students in classroom, clinical, and assessment settings align. METHOD: A mixed methods study was conducted to observe and evaluate students during the fourth year of a five-year medical program. Participants were videorecorded during structured classroom 'interactional skills' sessions, as well as clinical encounters with real patients and an OSCE station calling upon communication skills. The Calgary Cambridge Observational Guides was used to evaluate students at different settings. RESULT: This study observed 28 students and findings revealed that while in the classroom students were able to practise a broad range of communication skills, in contrast in the clinical environment, information-gathering and relationship-building with patients became the focus of their encounters with patients. In the OSCEs, limited time and high-pressure scenarios caused the students to rush to complete the task which focussed solely on information-gathering and/or explanation, diminishing opportunity for rapport-building with the patient. CONCLUSION: These findings indicate a poor alignment that can develop between the skills practiced across learning environments. Further research is needed to investigate the development and application of students' skills over the long term to understand supports for and barriers to effective teaching and learning of communication skills in different learning environments.

RESUMEN

Urethral sphincter insufficiency following radical prostatectomy (RP) is a common cause of non-neurogenic stress urinary incontinence (SUI). Artificial urinary sphincter (AUS) insertion remains the standard of care for fit patients with SUI refractory to non-operative interventions. The proximal urethra is a common location for uncomplicated AUS placement. However, previous failed AUS, urethroplasty, or pelvic radiotherapy (RT) may compromise urethral tissue requiring technique modifications that optimise outcomes. In these situations, transcorporal cuff (TC) placement has been well described to facilitate continence restoration in men where there is no other feasible option other than urinary diversion or permanent incontinence. In the traditional TC approach, the procedure may be complicated by haematoma due to difficulty in completely closing the corporal defects behind the urethra. This narrated video demonstrates the tunical flap (TF) modification for transcorporal AUS implantation via a perineal and penoscrotal approach in patients with prior failed AUS placements secondary to urethral erosion. The TF technique for transcorporal AUS insertion provides circumferential reinforcement with tunica albuginea from the corpora cavernosa. Here, we show how this technique provides additional urethral support for compromised urethral tissue to help prevent cuff erosion. The TF preserves the corporal volume and does not limit candidacy for future penile prosthesis implantation. In our early results, there have been no postoperative haematoma formation with this technique.

RESUMEN

BACKGROUND: We aimed to define levels of unmet supportive care needs in people with primary brain tumor and to reach expert consensus on feasibility of addressing patients' needs in clinical practice. METHODS: We conducted secondary analysis of a prospective cohort study of people diagnosed with high-grade glioma (n = 116) who completed the Supportive Care Needs Survey-Short Form during adjuvant chemoradiation therapy. Participants were allocated to 1 of 3 categories: no need ("no need" for help on all items), low need ("low need" for help on at least 1 item, but no "moderate" or "high" need), or moderate/high need (at least 1 "moderate" or "high" need indicated). Clinical capacity to respond to the proportion of patients needing to be prioritized was assessed. RESULTS: Overall, 13% (n = 5) were categorized as no need, 23% (n = 27) low need, and 64% (n = 74) moderate/high need. At least 1 moderate/high need was reported in the physical and daily living domain (42%) and the psychological (34%) domain. In recognition of health system capacity, the moderate/high need category was modified to distinguish between moderate need ("moderate" need indicated for at least 1 item but "high" need was not selected for any item) and high need (at least 1 "high" need indicated). Results revealed 24% (n = 28) moderate need and 40% (n = 46) high need. Those categorized as high need indicated needing assistance navigating the health system and information. CONCLUSIONS: Using four step allocations resulted in 40% of patients indicating high need. Categories may facilitate appropriate triaging and guide stepped models of healthcare delivery.

RESUMEN

Cancer is the primary underlying condition for most Canadians who are provided Medical Assistance in Dying (MAID). However, it is unknown whether cancer patients who are provided MAID experience disproportionally higher symptom burden compared to those who are not provided MAID. Thus, we used a propensity-score-matched cohort design to evaluate longitudinal symptom trajectories over the last 12 months of patients' lives, comparing cancer patients in Alberta who were and were not provided MAID. We utilized routinely collected retrospective Patient-Reported Outcomes (PROs) data from the Edmonton Symptom Assessment System (ESAS-r) reported by Albertans with cancer who died between July 2017 and January 2019. The data were analyzed using mixed-effect models for repeated measures to compare differences in symptom trajectories between the cohorts over time. Both cohorts experienced increasing severity in all symptoms in the year prior to death (ß from 0.086 to 0.231, p ≤ .001 to .002). Those in the MAID cohort reported significantly greater anxiety (ß = -0.831, p = .044) and greater lack of appetite (ß = -0.934, p = .039) compared to those in the non-MAID cohort. The majority (65.8%) of patients who received MAID submitted their request for MAID within one month of their death. Overall, the MAID patients did not experience disproportionally higher symptom burden. These results emphasize opportunities to address patient suffering for all patients with cancer through routine collection of PROs as well as targeted and early palliative approaches to care.

RESUMEN

BACKGROUND: The relationship between overweight or obesity and depressive symptoms in individuals with or without cardio-metabolic abnormalities is unclear. In a cross-sectional study we examined the odds of experiencing depressive symptoms in overweight or obese older adults with or without metabolic abnormalities. METHODS: The participants included 3318 older adults from the Hunter Community Study Cohort with a Body Mass Index (BMI) ≥ 18.5 kgm2, stratified by BMI and metabolic health risk. Obesity was defined as BMI ≥ 30 kgm2 and metabolically healthy as the absence of metabolic risk factors, according to International Diabetic Federation criteria for metabolic syndromes. Moderate to severe depressive symptoms were defined as a Centre for Epidemiological Studies Depression Scale (CES-D) score ≥ 16. RESULTS: Compared to the metabolically healthy normal weight (MHNW) group, the odds of experiencing moderate/severe depressive symptoms were higher in those classified as a metabolically unhealthy normal weight (MUNW) (odds ratio (OR) = 1.25, 95% Confidence Interval (CI): 0.76-2.06) or metabolically unhealthy obesity (MUO) (OR = 1.48, 95% CI: 1.00-2.19), but not in those classified as metabolically unhealthy overweight (MUOW) (OR = 0.96, 95% CI: 0.63-1.45), metabolically healthy overweight (MHOW) (OR = 0.80, 95% CI: 0.51-1.26), and metabolically healthy obesity (MHO) (OR = 1.03, 95% CI: 0.65-1.64). Compared with MHNW males, the odds of moderate/severe depressive symptoms were increased in all other BMI category-metabolic health groups for males and females. LIMITATIONS: Our relatively small sample size and cross-sectional design did not allow us to robustly establish causality. CONCLUSION: The odds of experiencing moderate/severe depressive symptoms were increased in metabolically unhealthy older adults regardless of normal weight or obesity, with the odds of having moderate/severe depressive symptoms being higher in females than in males.

RESUMEN

Background: Depression is a significant global public health concern, affecting individuals across different age groups and cultural backgrounds. However, screening for depression remains an essential but often neglected aspect of healthcare, particularly in outpatient settings. This study aimed to assess the prevalence of depression among outpatients visiting the internal medicine department of the University Teaching Hospital of Kigali in Rwanda and evaluate the feasibility of implementing a depression screening program in this setting. Methods: An institution-based cross-sectional study design was employed, involving 300 adult medical outpatients through convenience sampling, aged 18 years and above, who visited the internal medicine department between October 7 to November 6, 2019. The Patient Health Questionnaire-9 (PHQ-9) was used as the screening tool to assess depressive symptoms. Additionally, socio-demographic and clinical data were collected to explore potential risk factors associated with depression using a binary logistic regression model. Results: A high prevalence of depression was identified among internal medicine outpatients, with 45.7% of participants screened positive for depression, with moderate, moderately severe, and severe depression accounting for 21%, 17%, and 8%, respectively. The following factors were significantly associated with positive screening for depression: lack of formal education (OR=4.463, p=0.011, 95% CI= [1.410; 14.127]), secondary education (OR=3.402, p=0.003, 95% CI= [1.517; 7.630]), low-income (OR=2.392, p=0.049, 95% CI= [1.003; 5.706]) and headache as a chief complaint (OR=3.611, p=0.001, CI= [1.718; 7.591]). Conclusion: This study highlights the high prevalence of depression among medical outpatients. Due to the stigma associated with mental health, patients frequently seek help for physical symptoms such as headaches and other bodily complaints rather than mental health concerns. Introducing routine depression screening in medical departments could potentially facilitate early identification, and intervention, and lead to improved patient care. Future research should focus on evaluating such screening programs' effectiveness and long-term outcomes in resource-limited settings like Rwanda.

RESUMEN

BACKGROUND AND AIMS: E-cigarette and other electronic nicotine delivery systems (ENDS) use has grown considerably over the past decade, with notable increases among young people. US state policy contexts for ENDS and tobacco may shape initiation into ENDS use among adolescents as they age into early adulthood. We aimed to determine whether state-level comprehensive vaping ban policies reduce the odds of youth initiation into ENDS use, net of additional state-level ENDS and tobacco policies, as well as the youth's cigarette smoking status. DESIGN: Longitudinal data from the Population Assessment of Tobacco and Health study were merged with a state-year database on tobacco and ENDS policies. Multivariable discrete-time event history models of ENDS initiation were estimated. SETTING: United States. PARTICIPANTS: Twenty thousand twelve youth assessed over six waves from 2013 to 2019 (n = 53 974 observations). MEASUREMENT: We examined comprehensive indoor vaping bans (i.e. 100% vape-free workplaces, restaurants and bars) as a key factor in initiation into ENDS use (i.e. first instance of vaping) from age 13 to 22. FINDINGS: Among young people, residing in a state with a comprehensive vaping ban was associated with 18% lower odds of ENDS initiation (odds ratio = 0.82; 95% confidence interval =[0.71, 0.94]), even after controlling for other state ENDS and tobacco policies, the youth's cigarette smoking and socio-demographic background and state-level covariates. CONCLUSIONS: In the United States, state-level vaping bans (i.e. 100% vape-free workplaces, restaurants and bars) are associated with reduced odds of youth initiation into electronic nicotine delivery systems use.

RESUMEN

As our understanding of the tumor microenvironment grows, the pathology field is increasingly utilizing multianalyte diagnostic assays to understand important characteristics of tumor growth. In clinical settings, brightfield chromogenic assays represent the gold-standard and have developed significant trust as the first-line diagnostic method. However, conventional brightfield tests have been limited to low-order assays that are visually interrogated. We have developed a hybrid method of brightfield chromogenic multiplexing that overcomes these limitations and enables high-order multiplex assays. However, how compatible high-order brightfield multiplexed images are with advanced analytical algorithms has not been extensively evaluated. In the present study, we address this gap by developing a novel 6-marker prostate cancer assay that targets diverse aspects of the tumor microenvironment such as prostate-specific biomarkers (PSMA and p504s), immune biomarkers (CD8 and PD-L1), a prognostic biomarker (Ki-67), as well as an adjunctive diagnostic biomarker (basal cell cocktail) and apply the assay to 143 differentially graded adenocarcinoma prostate tissues. The tissues were then imaged on our spectroscopic multiplexing imaging platform and mined for proteomic and spatial features that were correlated with cancer presence and disease grade. Extracted features were used to train a UMAP model that differentiated healthy from cancerous tissue with an accuracy of 89% and identified clusters of cells based on cancer grade. For spatial analysis, cell-to-cell distances were calculated for all biomarkers and differences between healthy and adenocarcinoma tissues were studied. We report that p504s positive cells were at least 2× closer to cells expressing PD-L1, CD8, Ki-67, and basal cell in adenocarcinoma tissues relative to the healthy control tissues. These findings offer a powerful insight to understand the fingerprint of the prostate tumor microenvironment and indicate that high-order chromogenic multiplexing is compatible with digital analysis. Thus, the presented chromogenic multiplexing system combines the clinical applicability of brightfield assays with the emerging diagnostic power of high-order multiplexing in a digital pathology friendly format that is well-suited for translational studies to better understand mechanisms of tumor development and growth.

RESUMEN

AIMS: The aims of this study were to measure whether household bans on vaping were associated with lower odds of youth past-month vaping when compared with (1) otherwise similar youth whose households did not have a vaping ban (using coarsened exact matching); and (2) themselves in waves when their household did not have a ban (using hybrid panel models). We used the same analytical strategies to examine cross-sectional associations between household smoking bans and adolescents' past-month cigarette smoking. DESIGN: This was a longitudinal study using data from a nationally representative sample of youth (age 12-17 years) in the Population Assessment of Tobacco and Health Study. SETTING: United States of America. PARTICIPANTS: A total of 16 214 adolescents followed over 48 103 total observations (approximately three waves). MEASUREMENTS: Measurements comprised youth past-month e-cigarette and cigarette use and parent-reported household bans on vaping and smoking. Potential confounders were prior adolescent smoking, vaping, and other nicotine product use; parent current smoking, vaping, and other nicotine use; adolescent peer e-cigarette/cigarette use; parental monitoring; and demographic characteristics. FINDINGS: Before matching, smoking bans were associated with 46% lower odds of youth smoking [odds ratio (OR) = 0.54; 95% confidence interval (CI) = 0.41-0.70] and vaping bans with 37% lower odds of youth e-cigarette use (OR = 0.63; 95% CI = 0.50-0.80). However, households with and without bans differed significantly on all confounders before matching. After matching, household vaping bans were associated with 56% lower odds of youth vaping (OR = 0.44; 95% CI = 0.33-0.58). Results from hybrid panel models also revealed 37% lower odds of vaping in waves when youth lived in a vape-free household compared to waves when they did not (OR = 0.63; 95% CI = 0.50-0.78). Associations between smoking bans and youth smoking were not statistically significant after matching or when using hybrid panel models. CONCLUSIONS: Household vaping bans appear to be associated with lower odds of past-month vaping among US adolescents, compared with similar youth whose households did not have a ban and to themselves in waves when their households did not have a ban.

RESUMEN

There is growing recognition that the public health measures employed to control the spread of the COVID-19 pandemic had unintended consequences on socioeconomic security and health inequalities, having the greatest impact on the most vulnerable groups. This longitudinal study aims to explore the medium to long-term impacts of the COVID-19 pandemic and subsequent public health measures on financial security for families living in the deprived and ethnically diverse city of Bradford. We collected data at four time points before and during the pandemic from mothers who participated in one of two prospective birth cohort studies in Bradford. The findings demonstrate that the risk of experiencing financial insecurity rose sharply during the pandemic and has not returned to pre-COVID-19 baseline levels. Several individual characteristics were found to be possible predictors of financial insecurity, including homeowner status, free school meal eligibility and not working. Protective factors against financial insecurity include: living in more affluent areas; greater levels of educational attainment; and families with two or more adults in the household. Notably, families of Pakistani Heritage were found to have the greatest risk of experiencing financial insecurity throughout the pandemic. Furthermore, this study demonstrated that there were strong associations between financial insecurity and maternal health and wellbeing outcomes, with mothers experiencing financial insecurity being more likely to report unsatisfactory general health and clinically important symptoms of depression and anxiety. The findings of this study highlight that the impact of financial insecurity experienced by mothers and their families throughout the pandemic was severe, wide ranging and affected the most vulnerable. In the wake of the pandemic, the emerging cost of living and energy crisis emphasises the urgent need for policy makers to act to support vulnerable families to prevent further widening of existing health and social inequalities.
