Exploring the research needs, barriers and facilitators to the collection of biological data in adolescence for mental health research: a scoping review protocol paper.

INTRODUCTION: While research into adolescent mental health has developed a considerable understanding of environmental and psychosocial risk factors, equivalent biological evidence is lacking and is not representative of economic, social and ethnic diversity in the adolescent population. It is important to understand the possible barriers and facilitators to conduct this research. This will then allow us to improve our understanding of how biology interacts with environmental and psychosocial risk factors during adolescence. The objective of this scoping review is to identify and understand the needs, barriers and facilitators related to the collection of biological data in adolescent mental health research. METHODS AND ANALYSIS: Reviewers will conduct a systematic search of PubMed, Medline, Scopus, Cochrane, ERIC, EMBASE, ProQuest, EBSCO Global Health electronic databases, relevant publications and reference lists to identify studies published in the English language at any time. This scoping review will identify published studies exploring mental health/psychopathology outcomes, with biological measures, in participants between the ages of 11 and 18 and examine the reported methodology used for data collection. Data will be summarised in tabular form with narrative synthesis and will use the methodology of Levac et al, supplemented by subsequent recommendations from the Joanna Briggs Institute Scoping Review Methodology. ETHICS AND DISSEMINATION: Ethical approval is not required for this scoping review. The scoping review will be conducted with input from patient and public involvement, specifically including young people involved in our study ('Co-producing a framework of guiding principles for Engaging representative and diverse cohorts of young peopLE in Biological ReseArch in menTal hEalth'-www.celebrateproject.co.uk) Youth Expert Working Group. Dissemination will include publication in peer-reviewed journals, academic presentations and on the project website.

National survey of patient perspectives on cost discussions among recipients of copay assistance.

BACKGROUND: Individuals with cancer and other medical conditions often experience financial concerns from high costs-of-care and may utilize copay assistance programs (CAP). We sought to describe CAP recipients' experiences/preferences for cost discussions with clinicians. METHODS: We conducted a national, cross-sectional electronic-survey from 10/2022 to 11/2022 of CAP recipients with cancer or autoimmune conditions to assess patient perspectives on cost discussions. We used multivariable logistic regression models to explore associations of patient perspectives on cost discussions with patient characteristics and patient-reported outcomes (eg, financial toxicity, depression/anxiety, and health literacy). RESULTS: Among 1,566 participants, 71% had cancer and 29% had autoimmune conditions. Although 62% of respondents desired cost discussions, only 32% reported discussions took place. Additionally, 52% of respondents wanted their doctor to consider out-of-pocket costs when deciding the best treatment, and 61% of respondents felt doctors should ensure patients can afford treatment prescribed. Participants with depression symptoms were more likely to want doctors to consider out-of-pocket costs (OR = 1.54, P = .005) and to believe doctors should ensure patients can afford treatment (OR = 1.60, P = .005). Those with severe financial toxicity were more likely to desire cost discussions (OR = 1.65, P < .001) and want doctors to consider out-of-pocket costs (OR = 1.52, P = .001). Participants with marginal/inadequate health literacy were more likely to desire cost discussions (OR = 1.37, P = .01) and believe doctors should ensure patients can afford treatment (OR = 1.30, P = .036). CONCLUSIONS: In this large sample of CAP recipients with cancer and autoimmune conditions, most reported a desire for cost discussions, but under one-third reported such discussions took place.

Opening the doors of precision medicine: novel tools to assess intestinal barrier in inflammatory bowel disease and colitis-associated neoplasia.

Mounting evidence underscores the pivotal role of the intestinal barrier and its convoluted network with diet and intestinal microbiome in the pathogenesis of inflammatory bowel disease (IBD) and colitis-associated colorectal cancer (CRC). Moreover, the bidirectional association of the intestinal barrier with the liver and brain, known as the gut-brain axis, plays a crucial role in developing complications, including extraintestinal manifestations of IBD and CRC metastasis. Consequently, barrier healing represents a crucial therapeutic target in these inflammatory-dependent disorders, with barrier assessment predicting disease outcomes, response to therapy and extraintestinal manifestations.New advanced technologies are revolutionising our understanding of the barrier paradigm, enabling the accurate assessment of the intestinal barrier and aiding in unravelling the complexity of the gut-brain axis. Cutting-edge endoscopic imaging techniques, such as ultra-high magnification endocytoscopy and probe-based confocal laser endomicroscopy, are new technologies allowing real-time exploration of the 'cellular' intestinal barrier. Additionally, novel advanced spatial imaging technology platforms, including multispectral imaging, upconversion nanoparticles, digital spatial profiling, optical spectroscopy and mass cytometry, enable a deep and comprehensive assessment of the 'molecular' and 'ultrastructural' barrier. In this promising landscape, artificial intelligence plays a pivotal role in standardising and integrating these novel tools, thereby contributing to barrier assessment and prediction of outcomes.Looking ahead, this integrated and comprehensive approach holds the promise of uncovering new therapeutic targets, breaking the therapeutic ceiling in IBD. Novel molecules, dietary interventions and microbiome modulation strategies aim to restore, reinforce, or modulate the gut-brain axis. These advancements have the potential for transformative and personalised approaches to managing IBD.

Hypofractionated Radiotherapy-Related Lymphopenia Is Associated With Worse Survival in Unresectable Intrahepatic Cholangiocarcinoma.

OBJECTIVE: The aim of this study was to evaluate the incidence of radiotherapy (RT)-related lymphopenia, its predictors, and association with survival in unresectable intrahepatic cholangiocarcinoma (ICC) treated with hypofractionated-RT (HF-RT). METHODS: Retrospective analysis of 96 patients with unresectable ICC who underwent HF-RT (median 58.05 Gy in 15 fractions) between 2009 and 2022 was performed. Absolute lymphocyte count (ALC) nadir within 12 weeks of RT was analyzed. Primary variable of interest was severe lymphopenia, defined as Grade 3+ (ALC <0.5 k/µL) per CTCAE v5.0. Primary outcome of interest was overall survival (OS) from RT. RESULTS: Median follow-up was 16 months. Fifty-two percent of patients had chemotherapy pre-RT, 23% during RT, and 40% post-RT. Pre-RT, median ALC was 1.1 k/µL and 5% had severe lymphopenia. Post-RT, 68% developed RT-related severe lymphopenia. Patients who developed severe lymphopenia had a significantly lower pre-RT ALC (median 1.1 vs. 1.5 k/µL, P=0.01) and larger target tumor volume (median 125 vs. 62 cm3, P=0.02). In our multivariable Cox model, severe lymphopenia was associated with a 1.7-fold increased risk of death (P=0.04); 1-year OS rates were 63% vs 77% (P=0.03). Receipt of photon versus proton-based RT (OR=3.50, P=0.02), higher mean liver dose (OR=1.19, P<0.01), and longer RT duration (OR=1.49, P=0.02) predicted severe lymphopenia. CONCLUSIONS: HF-RT-related lymphopenia is an independent prognostic factor for survival in patients with unresectable ICC. Patients with lower baseline ALC and larger tumor volume may be at increased risk, and use of proton therapy, minimizing mean liver dose, and avoiding treatment breaks may reduce RT-related lymphopenia.

A family-centered approach to social needs awareness in the pediatric emergency department.

Objective: We aimed to understand family preferences around reporting and receiving health-related social needs (HRSN) information by assessment modality during pediatric emergency department (PED) visits. Methods: Families were randomized into paper (control), cell phone, or tablet modality groups by their child's exam room. Nurses alerted families to complete a single HRSN assessment during routine workflow. We used logistic regression and McNemar's test to assess discordance in modality preference. Results: Forty-seven percent of families disclosed at least one HRSN across a total 611 assessments. Disclosure of HRSN was similar by modality. Twenty-three percent of those assigned tablet preferred cell phone (p < 0.001). Two-thirds of families preferred receiving digitally formatted community resources (email or text). There was no difference in preferred timing of HRSN assessment completion. Conclusions: Assessment modality did not appear to influence family HRSN disclosure. Families were generally satisfied with all HRSN assessment modalities but demonstrated a particular preference in using personal cell phones over tablets. Digitally formatted community referrals also pose numerous advantages over conventional paper handouts. Innovation: Use of personal cell phones is a novel, streamlined method of HRSN interventions in the clinical setting, performing similar to more conventional modalities, with a preference among families when compared to tablets.

Examining mental health and autonomic function as putative mediators of the relationship between sleep and trajectories of cognitive function: findings from the Irish longitudinal study on ageing (TILDA).

OBJECTIVES: This study investigates the mediating roles of autonomic function and mental health in the association between sleep and cognitive decline in adults aged 50 and above. METHOD: A total of 2,697 participants with observations on sleep and mediators at baseline and repeated measures of cognitive function (MMSE) were included. Clusters of individuals with similar cognitive trajectories (high-stable, mid-stable and low-declining) were identified. Multinomial logistic regressions were used to estimate the likelihood of membership to each trajectory group based on sleep duration and disturbance. Finally, mediation analysis tested potential mediating effects of autonomic function and mental health underpinning the sleep-cognition relationship. RESULTS: Short (p = .028), long (p =.019), and disturbed sleep (p =.008) increased the likelihood of a low-declining cognitive trajectory. Mental health measures fully attenuated relationships between cognitive decline and short or disturbed sleep but not long sleep. No autonomic function mediation was observed. CONCLUSION: Older adults with short or disturbed sleep are at risk of cognitive decline due to poor mental health. Individuals with long sleep are also at risk, however, the acting pathways remain to be identified. These outcomes have clinical implications, potentially identifying intervention strategies targeting mental health and sleep as prophylactic measures against dementia.

Comparison of 3T MR arthrography and 3T MRI in intra-articular hip pathology: a cost-analysis.

BACKGROUND: MR arthrography (MRA) has previously been the radiological gold standard for investigating labral and chondral lesions of the hip joint. In recent years, 3T MRI has demonstrated comparable accuracy, being adopted as the first-line imaging investigation in many institutions. AIMS: We compare the associated increased cost and radiation dose of the fluoroscopic component of the MRA compared to MRI. METHODS: In this retrospective review over 2 years, 120 patients (mean age 27.3 years ± 13.2, range 8-67) underwent 3T MRA or non-contrast 3T MRI. Three musculoskeletal radiologists reported the data independently. Primary objectives included cost-comparison between each and radiation dose of the fluoroscopic component of the MRA. Secondary objectives included comparing detection of pathology involving the acetabular labrum, femoral cartilage, and acetabular cartilage. RESULTS: Then, 58 (48%) underwent 3T MRA and 62 (52%) patients underwent 3T MRI. The added cost of the fluoroscopic injection prior to MRA was €116.31/patient, equating to €7211.22 savings/year. MRA was associated with a small radiation dose of 0.003 mSv. CONCLUSIONS: Transitioning from 3T MRA to 3T MRI in the investigation of intra-articular hip pathology increases cost savings and reduces radiation dose.

Born in Bradford's Age of Wonder cohort: protocol for adolescent data collection.

Background: Adolescence and transition into adulthood are periods shaping life-long mental health, cardiometabolic risk, and inequalities. However, they are poorly studied and understood. By extending and expanding the Born in Bradford (BiB) cohort study through this period using innovative, co-produced approaches to collect and analyse data, we aim to understand better the interplay of factors that influence health and wellbeing, and inform/evaluate interventions to improve them and reduce inequalities. Protocol: BiB Age of Wonder (AoW) is a large, whole city cohort that will capture the contemporary lived experience amongst multi-ethnic adolescents progressing into young adulthood. We will collect repeated data from existing BiB participants and their peers (N~30,000 adolescents). The protocol for the first phase of the quantitative methods, involving survey measurements and health assessments in mainstream secondary schools is described here. We describe the co-production behind these methods, and lessons learned from the first year of data collection.

Born in Bradford have been following the health and wellbeing of over 13,000 Bradford children since they were born. This group of children are now in their teenage years ­ a time that is crucial for their future mental and physical health. Age of Wonder aims to capture this journey through adolescence and early adulthood with up to 30,000 young people in Bradford over 7 years. In the first phase of this project, data collection is taking part in secondary schools in Bradford. This protocol describes how this data collection is currently being carried out in the schools. Young people aged 12-15 are being asked to complete questionnaires, covering topics such as mental and physical health. These topics have been designed with groups of young people, schools and other partners, to make sure we are capturing data on the things most important to young people. Those in Year 9 (13-14 years old), are also asked to take part in physical health measurements such as height, weight, blood pressure and a blood sample, as well as computer-based assessments of cognition (memory), movement and language. There have been a number of lessons learned from the first full year of data collection, such as how to make the research as easy as possible for schools to take part in when they have so many competing demands on their time.

Application and demonstration of meso-activity exposure factors to advance estimates of incidental soil ingestion among agricultural workers.

BACKGROUND: Soil is an understudied and underregulated pathway of chemical exposure, particularly for agricultural workers who cultivate food in soils. Little is known about how agricultural workers spend their time and how they may contact soil while growing food. Exposure factors are behavioral and environmental variables used in exposure estimation. OBJECTIVES: Our study aimed to derive exposure factors describing how growers engage in different tasks and use those factors to advance the use of time-activity data to estimate soil ingestion exposures among agricultural workers. METHODS: We administered a meso-activity-based, season-specific soil contact activity questionnaire to 38 fruit and vegetable growers. We asked growers to estimate the frequency and duration of six meso-activities and describe how they completed them. We used questionnaire data to derive exposure factors and estimate empirical and simulated exposures to a hypothetical contaminant in soil via incidental ingestion using daily, hourly, and hourly-task-specific ingestion rates. RESULTS: We generated exposure factors characterizing the frequency and duration of six meso-activities by season, and self-reported soil contact, glove use, and handwashing practices by meso-activity and season. Seasonal average daily doses (ADDs) were similar across all three forms of ingestion rates. No consistent patterns regarding task-specific contributions to seasonal or annual ADDs were observed.

Palliative Care for Patients With Cancer: ASCO Guideline Update.

PURPOSE: To provide evidence-based guidance to oncology clinicians, patients, nonprofessional caregivers, and palliative care clinicians to update the 2016 ASCO guideline on the integration of palliative care into standard oncology for all patients diagnosed with cancer. METHODS: ASCO convened an Expert Panel of medical, radiation, hematology-oncology, oncology nursing, palliative care, social work, ethics, advocacy, and psycho-oncology experts. The Panel conducted a literature search, including systematic reviews, meta-analyses, and randomized controlled trials published from 2015-2023. Outcomes of interest included quality of life (QOL), patient satisfaction, physical and psychological symptoms, survival, and caregiver burden. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS: The literature search identified 52 relevant studies to inform the evidence base for this guideline. RECOMMENDATIONS: Evidence-based recommendations address the integration of palliative care in oncology. Oncology clinicians should refer patients with advanced solid tumors and hematologic malignancies to specialized interdisciplinary palliative care teams that provide outpatient and inpatient care beginning early in the course of the disease, alongside active treatment of their cancer. For patients with cancer with unaddressed physical, psychosocial, or spiritual distress, cancer care programs should provide dedicated specialist palliative care services complementing existing or emerging supportive care interventions. Oncology clinicians from across the interdisciplinary cancer care team may refer the caregivers (eg, family, chosen family, and friends) of patients with cancer to palliative care teams for additional support. The Expert Panel suggests early palliative care involvement, especially for patients with uncontrolled symptoms and QOL concerns. Clinicians caring for patients with solid tumors on phase I cancer trials may also refer them to specialist palliative care.Additional information is available at www.asco.org/supportive-care-guidelines.

The Emerging Role and Clinical Applications of Morphomics in Diagnostic Imaging.

Analytic morphomics refers to the accurate measurement of specific biological markers of human body composition in diagnostic medical imaging. The increasing prevalence of disease processes that alter body composition including obesity, cachexia, and sarcopenia has generated interest in specific targeted measurement of these metrics to possibly prevent or reduce negative health outcomes. Typical morphomic measurements include the area and density of muscle, bone, vascular calcification, visceral fat, and subcutaneous fat on a specific validated axial level in the patient's cross-sectional diagnostic imaging. A distinct advantage of these measurements is that they can be made retrospectively and opportunistically with pre-existing datasets. We provide a narrative review of the current state of art in morphomics, but also consider some potential future directions for this exciting field. Imaging based quantitative assessment of body composition has enormous potential across the breadth and scope of modern clinical practice. From risk stratification to treatment planning, and outcome assessment, all can be enhanced with the use of analytic morphomics. Moreover, it is likely that many new opportunities for personalized medicine will emerge as the field evolves. As radiologists, embracing analytic morphomics will enable us to contribute added value in the care of every patient.

Changes in Compliance with Bans on Tobacco Product Display and Advertising at Traditional and Modern Point-of-Sale Retailers in Depok, Indonesia, 2019-2021.

INTRODUCTION: Banning Point-of-Sale (POS) advertising and product display is an important tobacco control strategy. Depok, Indonesia enacted some regional tobacco control policies regulating the POS environment in 2021. This study examined changes in compliance before and after the implementation of these policies as of 2021. METHODS: Data collectors visited 180 modern retailers (hyper/supermarkets/convenience stores) and 147 traditional retailers (warungs) in 2019. The same retailers were re-visited in 2021. Data collectors assessed compliance with tobacco product display, and advertising regulations at POS, including if products were displayed in spaces to target minors (near candy or at a child's eye-level). Data were analyzed using McNemar and Mann-Whitney U tests. RESULTS: From 2019 to 2021, in modern retailers, tobacco product display (95.6% vs 52.2%) and product advertising (36.1% vs 3.9%) were significantly reduced (p<0.001). In traditional retailers, tobacco product display (94.6% in 2019, 91.2% in 2021, p>0.05) and product advertising (87.1% in 2019, 87.8% in 2021, p>0.05) remained common during both data collection periods. Tobacco products were commonly displayed in spaces to target minors in both modern retailers (43.3% in 2019, 34.4% in 2021, p>0.05) and traditional retailers (90.5% in 2019, 83.0% in 2021, p>0.05). CONCLUSIONS: Compliance with bans on tobacco product advertising and display at modern retailers improved significantly from 2019 to 2021; however, most modern retailers continue to display tobacco products in 2021. Traditional retailers remain largely non-compliant. Tobacco products are commonly displayed in areas that target minors. The enforcement of regional regulations should be strengthened, particularly among traditional retailers. IMPLICATIONS: In Depok, Indonesia, tobacco advertising and product display bans have been implemented; however, more work is needed to support compliance. Enforcement efforts, such as those carried out by civil police, can focus on tobacco product display bans in traditional and modern retailers, and traditional retailers need additional support to remove tobacco product advertising. Retailers may receive money from the tobacco industry for these advertisements. Creative solutions may include supporting retailers in finding alternative advertising revenue.

Social Care Education and Training Among US Pediatric Emergency Medicine Fellowship Programs.

OBJECTIVE: The aim of the study is to assess the association of social determinants of health (SDOH) education and social needs training on pediatric emergency medicine (PEM) physician perception and practices of social care. METHODS: Data were derived from the 2021 National Social Care Practices Survey of PEM program directors (PDs) and fellows. Ordinal and binary logistic regression modeling were completed for educational/training factors and social care perspective and practice outcomes. RESULTS: A national sample of 44 PDs (49% response rate) and 109 fellows (28%) participated. A minority of fellows received SDOH education and social needs training during fellowship. Fellows and PDs with SDOH education had a 3.1 odds (95% confidence interval CI, 1.4-6.9) of screening for social needs, with 4.4 odds among fellows (95% CI, 1.2-20.7). Those with social needs training were more comfortable assessing social risk, with 2.4 odds overall (95% CI, 1.2-4.7) and 3.1 odds among fellows (95% CI, 1.4-6.7). They also had 2.4 odds overall (95% CI, 1.1-4.9) of screening for social needs, with a 2.9 odds among fellows (95% CI, 1.3-6.8). CONCLUSIONS: Social care education and training appear to be associated with comfort assessing social risk and social needs screening tendency among both PEM PDs and fellows. Key areas for educational interventions are identified among PEM fellows, who are uniquely positioned as clinical leaders and patient advocates.

Ready, set, co(produce): a co-operative inquiry into co-producing research to explore adolescent health and wellbeing in the Born in Bradford Age of Wonder project.

BACKGROUND: Co-production of research with communities and stakeholders is recognised as best practice, but despite this, transparent reporting and reflective accounts on co-producing research is lacking. Born in Bradford Age of Wonder (AoW) is a large longitudinal health research project, following the health trajectories of up to 30,000 young people across the Bradford district; moreover, AoW has been entirely co-produced with teachers, parents, and young people. This paper describes the co-production of the Born in Bradford Age of Wonder (AoW) project and shares general reflections on co-production from peer researchers involved in co-producing AoW. METHODS: A co-operative inquiry (CI) approach was used to gather written reflections on co-production from ten peer researchers (one teacher, one parent, eight young people) involved in co-producing the AoW project. Written reflections were collected and rough "themes" were identified using thematic analysis. RESULTS: Four key 'themes' were identified: (1) promoting young people's voice and views (2) identifying impacts of co-production, (3) fostering a collaborative ethos, and (4) suggested improvements to the co-production work in AoW. Peer researchers' reflections highlighted how co-production can positively impact research projects such as AoW, whilst also holding broader benefits including giving young people a voice, facilitating their personal development, and fostering a collaborative ethos both within AoW and with partner organisations. Suggested improvements to AoW co-production included supporting greater numbers of young people and researchers to engage in co-production, organising more regular sessions, and establishing clearer communication channels. CONCLUSIONS: Peer researchers' reflections highlight positive impacts of engaging in co-production, both for research projects (including AoW) and for peer researchers' personal and professional development. That said, continued efforts are needed in AoW to meet young people's needs and interests, maintain trusting relationships, and foster sustained growth of co-production efforts within and beyond the AoW project. Evaluation of AoW co-production, along with wider partnership building are key to these efforts.

Born in Bradford (BiB) is a large health research programme, working to improve the health and wellbeing of people in Bradford and beyond. BiB Age of Wonder (AoW) is the next stage of the BiB programme and is collecting data on up to 30,000 teenagers across the Bradford district. A key part of BiB research (and AoW) involves working with community members as equal partners, through a process called co-production. Co-production is often seen as the best way to do health research; however, not all researchers agree on important questions such as what co-production really is, or why or how it is done. To answer these questions, we need to better understand the perspectives and experiences of those involved in co-production. This study gathered written reflections on co-production from young people, teachers and parents (described as peer researchers) involved in co-producing AoW. The study looked to capture peer researchers' experiences of doing co-production in general, what possible impact it has, and how co-production in AoW can be improved moving forward.Findings indicated that taking part in co-production can help peer researchers directly impact projects (including AoW), gain useful skills, and encourage collaboration within and beyond AoW. Suggested improvements to AoW co-production included having more regular sessions and having clearer communication with peer researchers. Whilst these findings indicate that AoW co-production is generally working well, an important next step is to evaluate the AoW co-production work and highlight key successes and challenges.

Transfer Learning Reveals Cancer-Associated Fibroblasts Are Associated with Epithelial-Mesenchymal Transition and Inflammation in Cancer Cells in Pancreatic Ductal Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy characterized by an immunosuppressive tumor microenvironment enriched with cancer-associated fibroblasts (CAF). This study used a convergence approach to identify tumor cell and CAF interactions through the integration of single-cell data from human tumors with human organoid coculture experiments. Analysis of a comprehensive atlas of PDAC single-cell RNA sequencing data indicated that CAF density is associated with increased inflammation and epithelial-mesenchymal transition (EMT) in epithelial cells. Transfer learning using transcriptional data from patient-derived organoid and CAF cocultures provided in silico validation of CAF induction of inflammatory and EMT epithelial cell states. Further experimental validation in cocultures demonstrated integrin beta 1 (ITGB1) and vascular endothelial factor A (VEGFA) interactions with neuropilin-1 mediating CAF-epithelial cell cross-talk. Together, this study introduces transfer learning from human single-cell data to organoid coculture analyses for experimental validation of discoveries of cell-cell cross-talk and identifies fibroblast-mediated regulation of EMT and inflammation. SIGNIFICANCE: Adaptation of transfer learning to relate human single-cell RNA sequencing data to organoid-CAF cocultures facilitates discovery of human pancreatic cancer intercellular interactions and uncovers cross-talk between CAFs and tumor cells through VEGFA and ITGB1.

Are brake response times altered post CT-guided cervical spine nerve root injections?

OBJECTIVES: To assess if brake response times are altered pre and post CT-guided cervical spine nerve root injections. METHODS: Brake response times were assessed before and after CT-guided cervical spine nerve root injections in a cohort of patients. The average of 3 brake response times was recorded before and 30 min after injection. Statistical analysis was performed using GraphPad. A paired Student t-test was used to compare the times before and after the injections. RESULTS: Forty patients were included in this study. The mean age was 55 years. There were 17 male and 23 female patients. There was no significant difference in the mean pre and post CT-guided cervical spine nerve root injection brake response times; 0.94 s (range 0.4-1.2 s) and 0.93 s (range 0.5-1.25 s), respectively (P = .77). CONCLUSIONS: Brake response time did not significantly differ pre and 30 min post CT-guided cervical spine nerve root injections. ADVANCES IN KNOWLEDGE: To the authors' best knowledge, there are no current studies assessing brake response times post CT-guided cervical spine nerve root injections. While driving safety cannot be proven by a single metric, it is a useful study in demonstrating that this is not inhibited in a cohort of patients.

E-cigarette 'tobacco flavor', how do I name thee? Let me count the ways.

INTRODUCTION: In recent years, hundreds of jurisdictions around the world have enacted policies that prohibit sales of flavored e-cigarettes. In most cases, these jurisdictions permit the sale of tobacco flavored e-cigarettes. We sought to understand how tobacco flavor in e-cigarette advertisements were presented. METHODS: Our sample included 2,966 US English language e-cigarette ads compiled by a market research firm, Numerator, that ran from January 2018 to December 2020. We describe the prevalence of different tobacco flavor names in our sample and classified each name into one of the following thematic categories: Traditional Tobacco, Pipe/Cigar Tobacco, Sensory Expectancies, Color, Physical Attribute, Place, and non-characterizing Concept flavor. RESULTS: In our sample, 28% (n=832/2,966) of ads promoted at least one tobacco flavored e-cigarette product (e-cigarette device or liquid). Across the 832 ads, we counted 1,019 tobacco flavored products and identified 51 unique tobacco flavor names. The most common tobacco flavor names were Traditional Tobacco names like 'Tobacco' (n=393), 'Classic tobacco' (n=107) and 'Original' (n=59). Some names were associated with Color (e.g., 'Golden tobacco'; n=153), Sensory Expectancy (e.g., 'Rich tobacco'; n=148), Place where tobacco cultivation takes place (e.g., 'Carolina tobacco'; n=83), Physical Attributes of tobacco (e.g., 'Cut tobacco'; n=17) and non-characterizing Concept flavor (e.g., 'Freedom juice'; n=14). Few tobacco flavors suggested a type of Pipe/Cigar Tobacco (e.g., 'Cavendish'; n=4). CONCLUSION: We identified 51 different tobacco flavor names, highlighting the practice describing the flavor beyond 'tobacco'. Future research can investigate whether these flavor names and descriptors influence consumers' perceptions, including perceived risks, of e-cigarette products. IMPLICATIONS: Flavors are used to market e-cigarettes. Globally, many jurisdictions restrict flavored e-cigarette sales, but few restrict tobacco flavor. This study identified 51 unique ways tobacco flavored e-cigarettes have been named in a sample of US English language ads, suggesting diversified ways to market 'tobacco.' We identified several sub-categories of tobacco flavor names that rely on Color, Sensory Expectancies, and non-characterizing Concept flavor attributes. As e-cigarette flavor restrictions that exempt tobacco flavor are still prevalent, this study highlights the need for continued monitoring of naming conventions of tobacco flavored products and examination of how nuanced flavor names influence perceptions and expectations.

Paediatric Thoracic Imaging in Cystic Fibrosis in the Era of Cystic Fibrosis Transmembrane Conductance Regulator Modulation.

Cystic fibrosis (CF) is one of the most common progressive life-shortening genetic conditions worldwide. Ground-breaking translational research has generated therapies that target the primary cystic fibrosis transmembrane conductance regulator (CFTR) defect, known as CFTR modulators. A crucial aspect of paediatric CF disease is the development and progression of irreversible respiratory disease in the absence of clinical symptoms. Accurate thoracic diagnostics have an important role to play in this regard. Chest radiographs are non-specific and insensitive in the context of subtle changes in early CF disease, with computed tomography (CT) providing increased sensitivity. Recent advancements in imaging hardware and software have allowed thoracic CTs to be acquired in paediatric patients at radiation doses approaching that of a chest radiograph. CFTR modulators slow the progression of CF, reduce the frequency of exacerbations and extend life expectancy. In conjunction with advances in CT imaging techniques, low-dose thorax CT will establish a central position in the routine care of children with CF. International guidelines regarding the choice of modality and timing of thoracic imaging in children with CF are lagging behind these rapid technological advances. The continued progress of personalised medicine in the form of CFTR modulators will promote the emergence of personalised radiological diagnostics.

Tobacco product litter as a form of postconsumption marketing: an observational study in India.

BACKGROUND: Tobacco product litter may be a form of postconsumption marketing if the littered items are branded. We conducted an observational study in India to assess the presence of tobacco product litter and determine the proportion that included branding. METHODS: During November-December 2022, we identified tobacco product litter (cigarette/bidi butts and packaging; smokeless tobacco packaging) in nine Indian cities: Bengaluru, Bhubaneswar, Chennai, Delhi, Guwahati, Hyderabad, Lucknow, Mumbai and Patna. In each city, we conducted observations along 15 different routes, each approximately 250 m in distance, for a total of 135 observational routes. Data collectors classified each piece of tobacco litter (product/packaging) and recorded if the litter had visible branding, such as brand names and/or logos. RESULTS: The study identified 17 261 pieces of tobacco product litter; SLT packaging comprised the largest proportion of the sample (62%), followed by cigarette butts (26%), bidi butts (8%), cigarette packaging (3%) and bidi packaging (1%). Across the sample, 81% (n=13 924) of the litter was branded. A brand was visible on most packaging for cigarettes (98%), bidis (97%) and SLT (86%), and present on 82% of cigarette butts and 26% of bidi butts. CONCLUSION: This study found that the majority of tobacco product litter in India is branded, which could function as a form of postconsumption marketing. Plain and standardised packaging and banning branding features on filters would reduce tobacco litter branding.

State of the literature discussing smoke-free policies globally: A narrative review.

Despite the success of the Framework Convention on Tobacco Control (FCTC), most jurisdictions in the world do not have policies that create 100% smoke-free environments in indoor workplaces, indoor public places, public transport, or other public places. We conducted a narrative review of articles that discuss smoke-free policies and describe the state of the current literature. A search of peer-reviewed and gray literature, published between 1 January 2004 and 30 April 2022, was conducted using PubMed and EMBASE databases. We classified articles based on the location of the policy discussed (WHO region, World Bank income classification) and the environment that was being made smoke-free. Insights related to policy development and implementation, as well as compliance and enforcement, were also identified. The search identified 4469 unique citations; 134 articles met the criteria for inclusion and underwent data extraction by two independent coders. The sample included articles published in or about jurisdictions in each WHO region, in high- and low- and mediumincome countries, and articles that discussed policies regulating smoke-free indoor workplaces, indoor public places, public transport, outdoor/quasi-outdoor environments, and other (unspecified) public places. Some important insights from the literature related to smoke-free policy implementation included tobacco industry interference, the important role of civil society, and the need for effective communication, education, and leadership. Enforcement officials' awareness and training, stakeholders' attitudes and beliefs, and understanding social norms were identified as relevant determinants of effective smoke-free policies. There continue to be challenges for implementing smoke-free policies in jurisdictions throughout the globe, in high- and low- and middle-income countries. The literature includes insights to support 100% smoke-free policies in each environment that must be made smoke-free as per the FCTC.
