Lifeguard Pharmacy: the co-development of a new community pharmacy response service for people in danger from domestic abuse or suicidal ideation.

BACKGROUND: Domestic abuse (DA) and suicidal ideation (SI) are prevalent and often co-occur. Numerous practical and psychosocial barriers inhibit help-seeking, including accessibility and confidentiality concerns. Pharmacies are accessible and may be perceived as a discreet venue for a DA and SI response service. OBJECTIVE: To co-develop a community pharmacy response service for people experiencing domestic abuse or suicidal ideation. METHODS: Overall, 36 unique individuals contributed at least once to a series of focus groups, interviews or workshops to co-develop the service components. Participants had lived experience of DA/SI or were professionals from DA/SI support services or pharmacies. Audio recordings and field notes from events were thematically analysed. Specific themes were identified and informed the development of the service components. KEY FINDINGS: Participants supported the development of this new service and considered community pharmacies to be an ideal setting. They thought of the service as a lifeline, that would offer hope. Under this main concept of hope, five main themes were identified: Safety, Empathy, Empowerment, Equity, and Discretion. Participants' practical considerations were incorporated into the service design, including the name choice of "Lifeguard Pharmacy", the strapline "Bringing Hope to Life", and the development of a "Client Flowchart" outlining how to welcome a client, arrange for a consultation, and then guide clients out of the pharmacy afterwards. CONCLUSIONS: Overall, the findings supported the development and introduction of this pharmacy-based intervention, which may help overcome barriers to help-seeking for DA or SI due to its sense of hope, accessibility, and discretion.

A conversation analytical study of call openings in Emergency Medical Service calls where the patient is at imminent risk of out-of-hospital cardiac arrest.

Background: The Chain of Survival identifies the importance of early recognition of patients who are at imminent risk of out-of-hospital cardiac arrest. This research investigated the interaction between callers and call-takers during calls to the Emergency Medical Service; it specifically focussed on patients who were alive at the initiation of the EMS call, but who subsequently deteriorated into out-of-hospital cardiac arrest during the prehospital phase of care (i.e., before arrival at hospital). Methods: Conversation-analytic methods were used to examine the call openings of 38 Emergency Medical Service calls for patients who were at imminent risk of out-of-hospital cardiac arrest. Call openings centred on pre-triage questions designed to rapidly identify patients who are either in out-of-hospital cardiac arrest, or who are at imminent risk of out-of-hospital cardiac arrest. Results: Emergency Medical Service call openings did not facilitate efficient and accurate triage, thus delaying the identification of critically unwell patients by call-takers. In 50% of call openings, the caller wanted to give the reason for the call during the pre-triage questions. The caller and call-takers orientate to different agendas causing delays to call progression and risking information loss that impacts on effective call triage. Conclusions: The design of the Emergency Medical Service call opening can cause interactional trouble, thus impacting on call progression and risking critical information loss. Modifications to the Emergency Medical Service call opening to quickly align the caller and call-taker, communications training for call-takers and public education may support early identification of patients at imminent risk of out-of-hospital cardiac arrest.

A mixed-methods cross-sectional study to evaluate the public acceptability of a novel pharmacy-based response service for domestic abuse and/or suicidal ideation.

BACKGROUND: Domestic abuse (DA) and suicidal ideation (SI) are prevalent and often co-occur. Numerous practical and psychosocial barriers inhibit help-seeking, including accessibility and confidentiality concerns. Early intervention and referral are essential for both DA and SI. Pharmacies are accessible and may be perceived as a discreet venue for a DA and SI response service. There is a growing body of literature about the role of community pharmacy teams in suicide prevention and assisting domestic abuse victims globally. Whilst there have been some interventions in UK pharmacies to support domestic abuse victims and encouragement of staff training in suicide prevention, there is currently no commissioned service for DA and/or SI in pharmacies in the UK. OBJECTIVE: To assess public acceptability of a novel response service in community pharmacy for people in danger from domestic abuse and/or suicidal ideation. METHODS: Data collection consisted of an online public survey running for 6 weeks and qualitative interviews with pharmacy customers. Descriptive statistics were used to present the survey results and interviews were audio recorded, transcribed verbatim and then analysed using the Framework Analysis method and NVivo 11. RESULTS: The majority of 501 survey respondents and all 12 customer interview participants were supportive of offering a response service for DA and/or SI in community pharmacy. Participants emphasised the need for appropriate staff training and support. They considered it an ethical and accessible approach and the majority said that they would recommend such a service to family or friends, and use it themselves if needed. However, awareness of the service was low and marketing materials were considered insufficiently clear. CONCLUSIONS: There is strong public support and acceptability for a response service covering both suicidal ideation and domestic abuse in community pharmacies. Further research is required to develop appropriate marketing materials.

Qualitative exploration of uterine cancer care for lesbian, gay, bisexual, trans and queer (LGBTQ+) patients in the UK: shifting from equality to equity.

OBJECTIVE: Patients identifying as lesbian, gay, bisexual, transgender and/or queer/questioning (LGBTQ+) report significant disparities in cancer care and are disproportionally affected by a cancer diagnosis on a number of health-related indicators. This study aimed to explore uterine cancer (UC) care from the perspectives of LGBTQ+ patients and stakeholders, to identify this population's care needs, which have been underprioritised thus far. METHODS AND ANALYSIS: Qualitative interview data were collected from three cohorts of participants: LGBTQ+ UC patients, partners of UC patients and stakeholders who provide advocacy and/or support within the UC care pathway, including healthcare professionals (HCPs). Semi-structured qualitative interviews were conducted and data were analysed using inductive reflexive thematic analysis. RESULTS: Fifteen participants (three patients, one partner, eight HCPs and three cancer support charity representatives) were recruited. Data analysis identified themes which represented participants' reflections on the relevance and opportunities for identity disclosure during the diagnostic pathway; feelings and implications of not fitting into the gynaecological cancer environment and, opportunities and challenges surrounding HCP education, and protocolled sexual and gender identity data collection. CONCLUSION: UC patients who identify as LGBTQ+ have specific care needs and considerations, particularly related to transvaginal procedures and survivorship. Opportunities for disclosure of patients' LGBTQ+ identity during the UC care pathway are essential for these needs to be recognised. Despite this, there are conflicting agendas between HCPs and stakeholders on the best approach to integrate disclosure processes. The current findings highlight the need for public health agendas and clinical services to address the needs of LGBTQ+ UC patients.

Safety-netting advice documentation out-of-hours: a retrospective cohort from 2013 to 2020.

BACKGROUND: Providing safety-netting advice (SNA) in out-of-hours primary care is a recognised standard of safe care but it is not known how frequently this occurs in practice. AIM: Assess the frequency and type of SNA documented in out-of-hours primary care and explore factors associated with its presence. DESIGN AND SETTING: Retrospective cohort using the Birmingham Out-of-hours General Practice Research Database. METHOD: A stratified sample of 30 adult consultation records per month from July 2013 to February 2020 were assessed using a safety-netting coding tool. Associations were tested using linear and logistic regression. RESULTS: The overall frequency of SNA per consultation was 78.0%, increasing from 75.7% (2014) to 81.5% (2019). The proportion of specific SNA and the average number of symptoms patients were told to look out for increased with time. The most common symptom to look out for was if the patients' condition worsened followed by if their symptoms persisted, but only one in five consultations included a time-frame to reconsult for persistent symptoms. SNA was more frequently documented in face-to-face treatment-centre encounters compared to telephone-consultations (Odds Ratio [OR]=1.77, p=0.02), for possible infections (OR=1.53, p=0.006), and less frequently for mental (vs. physical) health consultations (OR=0.33, p=0.002) and where follow-up was planned (OR=0.34, p<0.001). CONCLUSION: The frequency of SNA documented in OOH was higher than previously reported during in-hours care. Over time, the frequency of SNA and proportion that contained specific advice increased, however this study highlights potential consultations where SNA could be improved, such as mental health and telephone consultations.

Communication in Primary Healthcare: A State-of-the-Art Literature Review of Conversation-Analytic Research.

We report the first state-of-the-art review of conversation-analytic (CA) research on communication in primary healthcare. We conducted a systematic search across multiple bibliographic databases and specialist sources and employed backward and forward citation tracking. We included 177 empirical studies spanning four decades of research and 16 different countries/health systems, with data in 17 languages. The majority of studies originated in United States and United Kingdom and focused on medical visits between physicians and adult patients. We generated three broad research themes in order to synthesize the study findings: managing agendas, managing participation, and managing authority. We characterize the state-of-the-art for each theme, illustrating the progression of the work and making comparisons across different languages and health systems, where possible. We consider practical applications of the findings, reflect on the state of current knowledge, and suggest some directions for future research. Data reported are in multiple languages.

The association between restricted activity and patient outcomes in older adults: systematic literature review and meta-analysis.

BACKGROUND: Restricted activity is a potential early marker of declining health in older adults. Previous studies of this association with patient outcomes have been inconclusive. This review aimed to evaluate the extent to which restricted activity is associated with decline in health. METHODS: A search was conducted for studies including people over 65 years old which investigated the association between measures of restricted activity and hospitalisation, cognitive decline, and mortality. Following data extraction by two reviewers, eligible studies were summarised using Inverse Variance Heterogeneity meta-analysis. RESULTS: The search identified 8,434 unique publications, with 11 eligible studies. Three measures of restricted activity were identified: bed rest, restricted movement, and dependency for activities of daily living (ADL). Three studies looked at hospitalisations, with two finding a significant association with bed rest or restricted movement and one showing no evidence of an association. Restricted activity was associated with a significant increase in mortality across all three measures (bed rest odds ratio [OR] 6.34, 95%CI 2.51-16.02, I2 = 76%; restricted movement OR 5.38 95%CI 2.60-11.13, I2 = 69%; general ADL dependency OR 4.65 95%CI 2.25-9.26, I2 = 84%). The significant heterogeneity observed could not be explained by restricting the analysis by length of follow-up, or measure of restricted activity. No meta-analysis was conducted on the limited evidence for cognitive decline outcomes. CONCLUSIONS: Limited studies have considered the prognostic value of restricted activity in terms of predicting future declining health. Current evidence suggests restricted activity is associated with hospitalisation and mortality, and therefore could identify a group for whom early intervention might be possible.

Soil microbiome feedbacks during disturbance-driven forest ecosystem conversion.

Disturbances cause rapid changes to forests, with different disturbance types and severities creating unique ecosystem trajectories that can impact the underlying soil microbiome. Pile burning-the combustion of logging residue on the forest floor-is a common fuel reduction practice that can have impacts on forest soils analogous to those following high-severity wildfire. Further, pile burning following clear-cut harvesting can create persistent openings dominated by nonwoody plants surrounded by dense regenerating conifer forest. A paired 60-year chronosequence of burn scar openings and surrounding regenerating forest after clear-cut harvesting provides a unique opportunity to assess whether belowground microbial processes mirror aboveground vegetation during disturbance-induced ecosystem shifts. Soil ectomycorrhizal fungal diversity was reduced the first decade after pile burning, which could explain poor tree seedling establishment and subsequent persistence of herbaceous species within the openings. Fine-scale changes in the soil microbiome mirrored aboveground shifts in vegetation, with short-term changes to microbial carbon cycling functions resembling a postfire microbiome (e.g. enrichment of aromatic degradation genes) and respiration in burn scars decoupled from substrate quantity and quality. Broadly, however, soil microbiome composition and function within burn scar soils converged with that of the surrounding regenerating forest six decades after the disturbances, indicating potential microbial resilience that was disconnected from aboveground vegetation shifts. This work begins to unravel the belowground microbial processes that underlie disturbance-induced ecosystem changes, which are increasing in frequency tied to climate change.

Cadaveric aortic aneurysm creation: A life-like model for training endovascular repair.

The recent decline in RAAA incidence and the fast paced scenario with associated challenges regarding training calls for initiative for a better training environment to maximize learning. This led us to the creation of a pulsatile human cadaveric RAAA model. Fresh frozen cadaver was used to create RAAA with BioTissue in hybrid suite with ability to perform CBCTA for sizing. As a proof of concept, the model was used to perform REVAR with proximal CODA balloon control. The model proved to be feasible and we believe it is a better environment to train and gain adequate proficiency in RAAA management.

Ideas, concerns, expectations, and effects on life (ICEE) in GP consultations: an observational study using video-recorded UK consultations.

BACKGROUND: Eliciting patients' ideas, concerns, expectations, and whether a problem has an 'effect' on their life (ICEE), is a widely recommended communication technique. However, it is not known how frequently ICEE components are raised in UK GP consultations. AIM: To assess the frequency of ICEE in routine GP consultations with adult patients and explore variables associated with ICEE. DESIGN & SETTING: An observational study was undertaken. It involved secondary analysis of a pre-existing archive of video-recorded, face-to-face GP consultations in the UK. METHOD: Observational coding of 92 consultations took place. Associations were assessed using binomial and ordered logistic regression. RESULTS: Most consultations included at least one ICEE component (90.2%). The most common ICEE component per consultation was patient ideas (79.3%), followed by concerns (55.4%), expectations (51.1%), and then effects on life (42.4%). For all ICEE components patients more commonly initiated the ICEE dialogue, and in only three consultations (3.3%) did GPs directly ask patients about their expectations. Problems that were acute (odds ratio [OR] 2.98, 95% confidence interval [CI] = 1.36 to 6.53, P = 0.007) or assessed by GPs aged ≥50 years (OR 2.10, 95% CI = 1.07 to 4.13, P = 0.030) were associated with more ICEE components. Problems assessed later in the consultation (OR 0.60 per problem order increase, 95% CI = 0.41 to 0.87, P = 0.007) by patients aged ≥75 years (OR 0.40, 95% CI = 0.16 to 0.98, P = 0.046) and from the most deprived cohort (OR 0.39, 95% CI = 0.17 to 0.92, P = 0.032) were associated with fewer ICEE components. Patient ideas were associated with more patients being 'very satisfied' post-consultation (OR 10.74, 95% CI = 1.60 to 72.0, P = 0.014) and the opposite was true of concerns (OR 0.14, 95% CI = 0.02 to 0.86, P = 0.034). CONCLUSION: ICEE components were associated with patient satisfaction and demographic variables. Further research is required to assess if the way ICEE are communicated affects these associations and other potential confounders.

Exploring early career researchers' perspectives of training and funding opportunities: Motivations and setbacks when applying for the UK's National Institute for Health and Care Research's fellowships and research funding.

Despite the availability of training and funding opportunities with the UK's National Institute for Health and Care Research (NIHR), early career researchers (ECRs) invariably experience concern in sustaining an academic career in health research given the uncertainties of success following rejection from peer-reviewed funding bodies. The objective of this study was to consider what motivates ECRs when applying for funding to NIHR programmes and how they overcome funding setbacks. Eleven ECRs took part in a one-to-one virtual in-depth interview; the sample included more women (n = 8) than men (n = 3) and participants included pre-doctoral researchers (n = 5), and both doctoral (n = 2) and post-doctoral (n = 4) ECRs. The interviews were analysed using the logic of a systems theory framework identifying factors impacting on ECRs occurring within an individual, within their social system and within their broader environment. The central themes that emerged from the data focussed on: (1) facilitators for ECRs to apply for NIHR funding; (2) exploring ECRs' setbacks and disappointments; (3) improving chances of funding; and (4) deciding to apply with a view to re-applying in future. The participants' responses provided an honest and frank reflection of the uncertainties and challenges as ECRs in the current climate. Further strategies to support ECRs could be facilitated through local NIHR infrastructure, mentorship, better access to local support networks and hard-wiring research into an organisation's strategic priorities.

Agreement between patient's description of abdominal symptoms of possible upper gastrointestinal cancer and general practitioner consultation notes: a qualitative analysis of video-recorded UK primary care consultation data.

INTRODUCTION: Abdominal symptoms are common in primary care but infrequently might be due to an upper gastrointestinal (UGI) cancer. Patients' descriptions may differ from medical terminology used by general practitioners (GPs). This may affect how information about abdominal symptoms possibly due to an UGI cancer are documented, creating potential missed opportunities for timely investigation. OBJECTIVES: To explore how abdominal symptoms are communicated during primary care consultations, and identify characteristics of patients' descriptions that underpin variation in the accuracy and completeness with which they are documented in medical records. METHODS AND ANALYSIS: Primary care consultation video recordings, transcripts and medical records from an existing dataset were screened for adults reporting abdominal symptoms. We conducted a qualitative content analysis to capture alignments (medical record entries matching patient verbal and non-verbal descriptions) and misalignments (symptom information omitted or differing from patient descriptions). Categories were informed by the Calgary-Cambridge guide's 'gathering information' domains and patterns in descriptions explored. RESULTS: Our sample included 28 consultations (28 patients with 18 GPs): 10 categories of different clinical features of abdominal symptoms were discussed. The information GPs documented about these features commonly did not match what patients described, with misalignments more common than alignments (67 vs 43 instances, respectively). Misalignments often featured patients using vague descriptors, figurative speech, lengthy explanations and broad hand gestures. Alignments were characterised by patients using well-defined terms, succinct descriptions and precise gestures for symptoms with an exact location. Abdominal sensations reported as 'pain' were almost always documented compared with expressions of 'discomfort'. CONCLUSIONS: Abdominal symptoms that are well defined or communicated as 'pain' may be more salient to GPs than those expressed vaguely or as 'discomfort'. Variable documentation of abdominal symptoms in medical records may have implications for the development of clinical decision support systems and decisions to investigate possible UGI cancer.

Selection of motion management in liver stereotactic body radiotherapy and its impact on treatment time.

Background and purpose: Reduction of respiratory tumour motion is important in liver stereotactic body radiation therapy (SBRT) to reduce side effects and improve tumour control probability. We have assessed the distribution of use of voluntary exhale breath hold (EBH), abdominal compression (AC), free breathing gating (gating) and free breathing (FB), and the impact of these on treatment time. Materials and Methods: We assessed all patients treated in a single institution with liver SBRT between September 2017 and September 2021. Data from pre-simulation motion management assessment using fluoroscopic assessment of liver dome position in repeat breath holds, and motion with and without AC, was reviewed to determine liver dome position consistency in EBH and the impact of AC on motion. Treatment time was assessed for all fractions as time from first image acquisition to last treatment beam off. Results: Of 136 patients treated with 145 courses of liver SBRT, 68 % were treated in EBH, 20 % with AC, 7 % in gating and 5 % in FB. AC resulted in motion reduction < 1 mm in 9/26 patients assessed. Median treatment time was higher using EBH (39 min) or gating (42 min) compared with AC (30 min) or FB (24 min) treatments. Conclusions: Motion management in liver SBRT needs to be assessed per-patient to ensure appropriate techniques are applied. Motion management significantly impacts treatment time therefore patient comfort must also be taken into account when selecting the technique for each patient.

Evaluation of a Novel System for RFID Intraoperative Cardiovascular Analytics.

Objective: To evaluate a novel technology for real time tracking of RF-Identified (RFID) surgical tools (Biotic System), providing intraoperative data analytics during simulated cardiovascular procedures. Ineffective asset management in the Operating Room (OR) leads to inefficient utilization of resources and contributes to prolonged operative times and increased costs. Analysis of captured data can assist in quantifying instrument utilization, procedure flow, performance and prevention of retained instruments. Methods & Results: Five surgeons performed thirteen simulated surgical cases on three human cadavers. Procedures included (i) two abdominal aortic aneurysm (AAA) repairs, (ii) three carotid endarterectomies (CE), (iii) two femoropopliteal (fem-pop) bypasses, (iv) thoracic aortic aneurysm repair, (v) coronary artery bypass graft, (vi) aortic valve replacement, (vii) ascending aortic aneurysm repair, (viii) heart transplants, and (ix) mitral valve replacement. For each case an average of 139 surgical instruments were RFID-tagged and tracked intraoperatively. Data was captured and analyzed retrospectively. Of the 139 instruments tracked across each of the 13 cases, 55 instruments (39.5%) were actually used, demonstrating a high level of redundancy. For repeat cases (i.e. CE/AAA/fem-pop): (i) average instrument usage was 41 ± 3.6 (8.8% variation) for CE (n=3); (ii) average instrument usage was 69 ± 4.0 (5.8% variation) for AAA (n=2); and (iii) average instrument usage was 48 ± 2.5 (5.3% variation) for fem- pop (n=2). Results also showed a reduction in end-of-procedure instrument counting times of 58-87%. Conclusions: We report on a method for collecting intraoperative data analytics regarding instrument usage via RFID technology. This system will help refine instrument selection, quantitate instrument utilization and prevent inadvertent retention in a patient. This should help increase efficiency in packaging and sterilization and let surgeons make objective decisions in the composition of surgical trays. Clinical and Translational Impact Statement-Intraoperative analytics of surgical tools and associated equipment may ultimately lead to safer more efficient surgeries that increase patient outcomes while decreasing the cost of care.

"Maybe this is just not the place for me:" Gender harassment and discrimination in the geosciences.

Rampant gender-based harassment and discrimination are recognized problems that negatively impact efforts to diversify science, technology, engineering and mathematics (STEM) fields. We explored the particularities of this phenomenon in the geosciences, via focus groups conducted at STEM professional society meetings, with the goal of informing interventions specific to the discipline. Using grounded theory analysis, two primary drivers for the persistence and perpetuation of gender-based harassment in the geosciences were identified: a particular history of power dynamics and maintenance of dominant stereotypes, and a pattern of ineffective responses to incidents of harassment and discrimination. Informed by intersectional feminist scholarship by women of color that illustrates how efforts to address the underrepresentation of women in STEM without attending to the overlapping impacts of racism, colonialism, ableism, and classism will not succeed, we view harassment and discrimination as structural problems that require collective solutions. Continuing to recruit individuals into a discipline without changing its fundamental nature can tokenize and isolate them or encourage assimilation and acceptance of deep-seated traditions no matter how damaging. It is the responsibility of those in power, and especially those who hold more privileged status due to their social identities, to contribute to the dismantling of current structures that reinforce inequity. By providing explanatory illustrative examples drawn from first-person accounts we aim to humanize the numbers reported in workplace climate surveys, address gaps in knowledge specific to the geosciences, and identify interventions aligned with an intersectional framework that aim to disrupt discriminatory practices endemic to the geosciences and larger STEM community.

Endovascular Porcine Model of Iliocaval Venous Thrombosis.

OBJECTIVE: To develop a large animal model of iliocaval deep venous thrombosis (DVT), which enables development and evaluation of interventional management and existing imaging modalities. METHODS: The experimental protocol consisted of a total endovascular approach. Pigs were percutaneously accessed through the right internal jugular and bilateral femoral veins. Three balloon catheters were inflated to induce venous stasis in the infrarenal inferior vena cava (IVC) and bilateral common iliac veins (CIVs). Hypercoagulability was induced by injecting 10 000 IU of thrombin. After 2.5 hours, the balloon catheters were removed before animal recovery. After seven, 14, 21, 28, or 35 days, animals were euthanised; the IVC and CIV were harvested en bloc, cross sectioned and prepared for histological examination. Multimodal imaging was performed before and after thrombus creation, and before animal euthanasia. RESULTS: Thirteen female domestic pigs with a mean weight of 59.3 kilograms were used. The mean maximum IVC diameter and area were 16.4 mm and 1.2 cm2, respectively. The procedure was successful in 12 animals with occlusive venous thrombosis in the region of interest on immediate post-operative magnetic resonance venography and a mean thrombus volume of 19.8 cm3. Clinical pathology results showed platelet consumption, D dimer increase, and inflammatory response. Histological evaluation demonstrated a red cell, fibrin, and platelet rich thrombus on day 1, with progressive inflammatory cell infiltration from day 7. Collagen deposition appeared in week 2 and neovascularisation in week 3. CONCLUSION: Endovascular occlusion combined with thrombin infusion is a reliable minimally invasive approach to produce acute and subacute DVT in a large animal model.

Reimagine fire science for the anthropocene.

Fire is an integral component of ecosystems globally and a tool that humans have harnessed for millennia. Altered fire regimes are a fundamental cause and consequence of global change, impacting people and the biophysical systems on which they depend. As part of the newly emerging Anthropocene, marked by human-caused climate change and radical changes to ecosystems, fire danger is increasing, and fires are having increasingly devastating impacts on human health, infrastructure, and ecosystem services. Increasing fire danger is a vexing problem that requires deep transdisciplinary, trans-sector, and inclusive partnerships to address. Here, we outline barriers and opportunities in the next generation of fire science and provide guidance for investment in future research. We synthesize insights needed to better address the long-standing challenges of innovation across disciplines to (i) promote coordinated research efforts; (ii) embrace different ways of knowing and knowledge generation; (iii) promote exploration of fundamental science; (iv) capitalize on the "firehose" of data for societal benefit; and (v) integrate human and natural systems into models across multiple scales. Fire science is thus at a critical transitional moment. We need to shift from observation and modeled representations of varying components of climate, people, vegetation, and fire to more integrative and predictive approaches that support pathways toward mitigating and adapting to our increasingly flammable world, including the utilization of fire for human safety and benefit. Only through overcoming institutional silos and accessing knowledge across diverse communities can we effectively undertake research that improves outcomes in our more fiery future.

The old and familiar meets the new and unknown: patient and clinician perceptions on e-cigarettes for smoking reduction in UK general practice, a qualitative interview study.

BACKGROUND AND AIMS: Clinicians could promote e-cigarettes for harm reduction to people who smoke but cannot stop, but many clinicians feel uneasy doing so. In a randomized controlled trial (RCT), primary care clinicians offered free e-cigarettes and encouraged people with chronic diseases who were unwilling to stop smoking to switch to vaping. We interviewed clinicians and patients to understand how to adopt harm reduction in routine practice. DESIGN: Qualitative analysis nested within an RCT, comprising thematic analysis of semi-structured interviews with primary care clinicians who delivered the trial intervention, and patients who took part. SETTING: Primary care clinics in England. PARTICIPANTS/CASES: Twenty-one patients and 11 clinicians, purposively sampled from an RCT. MEASUREMENTS: We qualitatively explored patients' and clinicians' experiences of: being offered/offering an e-cigarette, past and current perceptions about e-cigarettes and applying a harm reduction approach. FINDINGS: Four themes captured clinicians' and patients' reported perspectives. These were: (1) concepts of safety/risk, with clinicians concerned about recommending a product with unknown long-term risks and patients preferring the known risks of cigarettes; (2) clinicians felt they were going out on a limb by offering these as though they were prescribing them, whereas patients did not share this view; (3) equating quitting with success, as both patients and clinicians conceptualized e-cigarettes as quitting aids; and (4) unchanged views, as clinicians reported that training did not change their existing views about e-cigarettes. These themes were united by the higher-order concept: 'The old and familiar meets the new and unknown', as a contradiction between this new approach and long-established methods underpinned these concerns. CONCLUSIONS: A qualitative analysis found barriers obstructing clinicians and patients from easily accepting e-cigarettes for harm reduction, rather than as aids to support smoking cessation: clinicians had difficulty reconciling harm reduction with their existing ethical models of practice, even following targeted training, and patients saw e-cigarettes as quitting aids.

Shifting stoichiometry: Long-term trends in stream-dissolved organic matter reveal altered C:N ratios due to history of atmospheric acid deposition.

Dissolved organic carbon (DOC) and nitrogen (DON) are important energy and nutrient sources for aquatic ecosystems. In many northern temperate, freshwater systems DOC has increased in the past 50 years. Less is known about how changes in DOC may vary across latitudes, and whether changes in DON track those of DOC. Here, we present long-term DOC and DON data from 74 streams distributed across seven sites in biomes ranging from the tropics to northern boreal forests with varying histories of atmospheric acid deposition. For each stream, we examined the temporal trends of DOC and DON concentrations and DOC:DON molar ratios. While some sites displayed consistent positive or negative trends in stream DOC and DON concentrations, changes in direction or magnitude were inconsistent at regional or local scales. DON trends did not always track those of DOC, though DOC:DON ratios increased over time for ~30% of streams. Our results indicate that the dissolved organic matter (DOM) pool is experiencing fundamental changes due to the recovery from atmospheric acid deposition. Changes in DOC:DON stoichiometry point to a shifting energy-nutrient balance in many aquatic ecosystems. Sustained changes in the character of DOM can have major implications for stream metabolism, biogeochemical processes, food webs, and drinking water quality (including disinfection by-products). Understanding regional and global variation in DOC and DON concentrations is important for developing realistic models and watershed management protocols to effectively target mitigation efforts aimed at bringing DOM flux and nutrient enrichment under control.
