Abstract
Compared to younger adults, older adults who smoke cigarettes are half as likely to make a quit attempt, but more likely to maintain abstinence using evidence-based smoking treatments (EBSTs), illustrating the need for motivational messages to promote cessation through EBSTs. It is unclear whether messaging regarding the association between smoking and dementia might motivate older adults to quit. We conducted 90-min semi-structured qualitative interviews and surveys via telephone with 24 U.S. older adults who smoke (ages 50-75) with no cognitive impairment history. Rapid content analysis revealed the most reported health-related concern of aging was dementia/cognitive loss/loss of functioning. However, most participants were unaware of the association between cognitive decline and smoking. Participants had seen previous smoking cessation advertisements, but most did not feel motivated to quit by them. The majority found a message about smoking raising dementia risk and quitting decreasing that risk to be motivational for cessation. Exact message content preference varied, but 2 broad categories arose: hope- and fear-based messages. Most participants stated willingness to use some cessation pharmacotherapy and half were willing to use cessation counseling. Participants preferred messages to come from older adults who were successful quitters. To our knowledge, this was the first study to explore potential motivational messages targeting older adult smokers, including the potential acceptability of a dementia-related message in this context. This work supports patient desire for targeted motivational messages for older adult smokers. Messages highlighting the link between smoking and dementia are perceived to be motivational for this group; future work should compare a hope- to fear-based messages.

Abstract
INTRODUCTION Female carriers of BRCA1/2 genes have an increased lifetime risk of breast cancer. Options for managing risk include imaging surveillance or risk-reducing surgery (RRS). This mixed methods study aimed to identify factors affecting risk-management decisions and the psychosocial outcomes of these decisions for high-risk women and their partners. METHODS Semi-structured qualitative interviews were performed with women at high breast cancer risk who had faced these choices. Partners were also interviewed. Analysis used a framework approach. A bespoke questionnaire was developed to quantify and explore associations. RESULTS A total of 32 women were interviewed. Of these, 27 had partners of whom 7 (26%) agreed to be interviewed. Four main themes arose: perception of risk and impact of increased risk; risk-management strategy decision-making; impact of risk-management strategy; support needs and partner relationship issues. The questionnaire response rate was 36/157 (23%). Decision satisfaction was high in both surveillance and RRS groups. Relationship changes were common but not universal. Common causes of distress following RRS included adverse body image changes. Both groups experienced generalised and cancer-specific anxiety. Drivers for surgery included having children, deaths of close family from breast cancer and higher levels of cancer anxiety. CONCLUSIONS Levels of psychosocial and decision satisfaction were high for women choosing both RRS and surveillance but, for a minority, risk-reducing measures result in long-term psychosocial morbidity. Efforts to recognise women at increased risk of psychological morbidity may allow targeted support.

Abstract
BACKGROUND Health care delivered by community health workers reduces morbidity and mortality while providing a considerable return on investment. Despite growing consensus that community health workers, a predominantly female workforce, should receive a salary, many community health worker programmes take the form of dual-cadre systems, where a salaried cadre of community health workers works alongside a cadre of unsalaried community health workers. We aimed to determine the presence, prevalence, and magnitude of exploitation in national dual-cadre programmes. METHODS We did a systematic review of available evidence from peer-reviewed databases and grey literature from database inception to Aug 2, 2021, for studies on unsalaried community health worker cadres in dual-cadre systems. Editorials, protocols, guidelines, or conference reports were excluded in addition to studies about single-tier community health worker programmes and those reporting on only salaried cadres of community health workers in a dual-cadre system. We extracted data on remuneration, workload, task complexity, and self-reported experiences of community health workers. Three models were created: a minimum model with the shortest time and frequency per task documented in the literature, a maximum model with the longest time, and a median model. Labour exploitation was defined as being engaged in work below the country's minimum wage together with excessive work hours or complex tasks. The study was registered with PROSPERO, CRD42021271500. FINDINGS We included 117 reports from 112 studies describing community health workers in dual-cadre programmes across 19 countries. The majority of community health workers were female. 13 (59%) of 22 unsalaried community health worker cadres and one (10%) of ten salaried cadres experienced labour exploitation. Three (17%) of 18 unsalaried community health workers would need to work more than 40 h per week to fulfil their assigned responsibilities. Unsalaried community health worker cadres frequently reported non-payment, inadequate or inconsistent payment of incentives, and an overburdensome workload. INTERPRETATION Unsalaried community health workers in dual-cadre programmes often face labour exploitation, potentially leading to inadequate health-care provision. Labour laws must be upheld and the creation of professional community health worker cadres with fair contracts prioritised, international funding allocated to programmes that rely on unsalaried workers should be transparently reported, the workloads of community health workers should be modelled a priori and actual time use routinely assessed, community health workers should have input in policies that affect them, and volunteers should not be responsible for the delivery of essential health services. FUNDING None.

Abstract
The workshop "Drug Permeability - Best Practices for Biopharmaceutics Classification System (BCS) Based Biowaivers" was held virtually on December 6, 2021, organized by the University of Maryland Center of Excellence in Regulatory Science and Innovation (M-CERSI), and the Food and Drug Administration (FDA). The workshop focused on the industrial, academic, and regulatory experiences in generating and evaluating permeability data, with the aim to further facilitate implementation of the BCS and efficient development of high-quality drug products globally. As the first international permeability workshop since the BCS based biowaivers was finalized as the ICH M9 guideline, the workshop included lectures, panel discussions, and breakout sessions. Lecture and panel discussion topics covered case studies at IND, NDA, and ANDA stages, typical deficiencies relating to permeability assessment supporting BCS biowaiver, types of evidence that are available to demonstrate high permeability, method suitability of a permeability assay, impact of excipients, importance of global acceptance of permeability methods, opportunities to expand the use of biowaivers (e.g. non-Caco-2 cell lines, totality-of-evidence approach to demonstrate high permeability) and future of permeability testing. Breakout sessions focused on 1) in vitro and in silico intestinal permeability methods; 2) potential excipient effects on permeability and; 3) use of label and literature data to designate permeability class.

Abstract
OBJECTIVE The aim of this study was to identify patterns of distress and growth in parents of children with cancer and examine associations with subsequent parenting, parent-child relationship, and family environment. METHODS Participants included children with cancer history (8-17 years) stratified by time since diagnosis and their parent. At enrollment, parents (n = 254) reported depression and anxiety, and post-traumatic stress symptoms, posttraumatic growth (PTG), and benefit finding in relation to their child's cancer. Three years later, children (n = 214) reported parenting behavior, parent reactions to their distress, and family environment. Parents reported their reaction to children's distress and qualities of the parent-child relationship. RESULTS Latent profile analysis empirically identified 3 cross-sectional profiles using baseline data: "Resilience, High Growth" (50%), characterized by the lowest distress and the highest PTG/benefit finding; "Moderate Distress with Growth" (33%), characterized by relatively high levels of all indicators; and "Resilience, Low Growth" (17%), characterized by relatively low distress with low PTG/benefit finding. Membership in profiles was associated with parent gender; parents' stressful life events; socioeconomic status; and child diagnosis, on versus off treatment status, and treatment intensity. Parent membership in the Moderate Distress with Growth profile was generally linked with poorer parenting behavior, parent-child relationship quality, and family functioning. CONCLUSION The majority of parents exhibited resilience and growth. However, a subset of parents displaying moderate distress may be at risk for subsequent parenting and family functioning challenges. Findings further highlight the importance of screening for even moderate parent distress and the possible impact of parent psychosocial interventions indirectly on parenting and family functioning.

Abstract
While past studies have suggested that plasticity exists between dermal fibroblasts and adipocytes, it remains unknown whether fat actively contributes to fibrosis in scarring. We show that adipocytes convert to scar-forming fibroblasts in response to Piezo -mediated mechanosensing to drive wound fibrosis. We establish that mechanics alone are sufficient to drive adipocyte-to- fibroblast conversion. By leveraging clonal-lineage-tracing in combination with scRNA-seq, Visium, and CODEX, we define a "mechanically naïve" fibroblast-subpopulation that represents a transcriptionally intermediate state between adipocytes and scar-fibroblasts. Finally, we show that Piezo1 or Piezo2 -inhibition yields regenerative healing by preventing adipocytes' activation to fibroblasts, in both mouse-wounds and a novel human-xenograft-wound model. Importantly, Piezo1 -inhibition induced wound regeneration even in pre-existing established scars, a finding that suggests a role for adipocyte-to-fibroblast transition in wound remodeling, the least-understood phase of wound healing. Adipocyte-to-fibroblast transition may thus represent a therapeutic target for minimizing fibrosis via Piezo -inhibition in organs where fat contributes to fibrosis.

Abstract
PURPOSE The energy density (ED) of a diet can be leveraged to prevent weight gain or treat overweight and obesity. By lowering the ED of the diet, energy intake can be reduced while maintaining portion size. However, a reliable meta-analysis of data from randomized controlled trials (RCTs) is missing. Therefore, this meta-analysis synthesized the evidence of ED manipulation on energy intake in RCTs. METHODS The systematic literature search of multiple databases according to PRISMA criteria considered RCTs investigating the objectively measured energy intake from meals with different ED (lower ED (median 1.1 kcal/g) versus higher ED (median 1.5 kcal/g)) under controlled conditions. Subgroup analyses for age (children versus adults), meal type (preload versus entrée design), and intervention length (1 meal versus > 1 meal) were performed to achieve the most homogeneous result. RESULTS The meta-analysis of 38 included studies demonstrated that lowering ED considerably reduced energy intake - 223 kcal (95% CI: - 259.7, - 186.0) in comparison to the higher ED interventions. As heterogeneity was high among studies, subgroup analyses were conducted. Heterogeneity decreased in subgroup analyses for age and meal type combined, strengthening the results. An extended analysis showed a positive linear relationship between ED and energy intake. Dietary ED did not affect the amount of food intake. CONCLUSION Manipulating ED substantially affects energy intake whereas food intake remains constant. Thus, this approach can be regarded as a powerful tool for weight management through nutrition therapy. Registration on 08/08/2021: CRD42021266653.

Abstract
OBJECTIVE To fulfill the requirements for bariatric surgery, patients often need to participate in mandatory preoperative lifestyle interventions. Currently, the efficacy of multi-month preoperative lifestyle intervention programs on body mass index (BMI) reduction from the start of the program (T0) through the immediate preoperative time point (T1) to 1 year post-surgery (T2) and how the amount of preoperative BMI reduction affects postoperative outcome (T1 to T2) is unclear. The aim of this meta-analysis was to analyze the effects of preoperative lifestyle interventions on BMI 1 year post-surgery. METHOD A systematic literature search was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Randomized controlled trials that implemented preoperative lifestyle interventions lasting 1-8 months before bariatric surgery were included. The BMI of the intervention group was compared with that of a control group before participation in the preoperative lifestyle interventions (T0), after completion of the program before surgery (T1), and 1 year post-surgery (T2). Finally, the impact of successful BMI reduction at T1 on BMI at T2 was analyzed. RESULTS N = 345 patients derived from 4 studies undergoing preoperative lifestyle interventions reduced their BMI at T1 by 1.5 units compared to the control group (95% CI: -2.73, -0.28). One year post-surgery, both groups had lost comparable BMI points. The influence of reduced BMI at T1 on weight status at T2 is unclear due to the lack of available studies. Other endpoints and subgroup analyses were rarely examined. CONCLUSIONS Preoperative lifestyle interventions reduce BMI before bariatric surgery more effectively than usual care. These differences are not detectable 1 year post-surgery. Although a short-term energy reduction period before surgery is clearly important to minimize surgery risks, it is currently unclear whether, and if so, under what circumstances, participation in a preoperative lifestyle intervention is beneficial.

Abstract
BACKGROUND Restraint and seclusion in an inpatient child and adolescent psychiatric population adversely affects the overall value and safety of care. Due to adverse events, negative outcomes, and associated costs, inpatient psychiatric hospitals must strive to reduce and ultimately eliminate restraint and seclusion with innovative, data-driven approaches. AIM To identify patterns of client characteristics that are associated with restraint and seclusion in an inpatient child and adolescent psychiatric population. METHOD A machine learning application of fast-and-frugal tree modeling was used to analyze the sample. RESULTS The need for restraint and seclusion were correctly predicted for 73% of clients at risk (sensitivity), and 76% of clients were correctly predicted as negative or low risk (specificity), for needing restraint and seclusion based on the following characteristics: having a disruptive mood dysregulation disorder and/or attention-deficit hyperactivity disorder diagnosis, being 12 years old or younger, and not having a depressive and/or bipolar disorder diagnosis. CONCLUSIONS The client characteristics identified in the predictive algorithm should be reviewed on admission to recognize clients at risk for restraint and seclusion. For those at risk, interventions should be developed into an individualized client treatment plan to facilitate a proactive approach in preventing behavioral emergencies requiring restraint and seclusion.

Abstract
BACKGROUND Breast cancer has a significant heritable basis, of which approximately 60% remains unexplained. Testing for BRCA1/BRCA2 offers useful discrimination of breast cancer risk within families, and identification of additional breast cancer susceptibility genes could offer clinical utility. PATIENTS AND METHODS We included 2,135 invasive breast cancer cases recruited via the BOCS study, a retrospective UK study of familial breast cancer. ELIGIBILITY CRITERIA female, BRCA-negative, white European ethnicity, and one of: i) breast cancer family history, ii) bilateral disease, iii) young age of onset (<30 years), iv) concomitant ovarian cancer. We undertook exome sequencing of cases and performed gene-level burden testing of rare damaging variants against those from 51,377 ethnicity-matched population controls from gnomAD. RESULTS 159/2135 (7.4%) cases had a qualifying variant in an established breast cancer susceptibility gene, with minimal evidence of signal in other cancer susceptibility genes. Known breast cancer susceptibility genes PALB2, CHEK2 and ATM were the only genes to retain statistical significance after correcting for multiple testing. Due to the enrichment of hereditary cases in the series, we had good power (>80%) to detect a gene of BRCA1-like risk (odds ratio = 10.6) down to a population minor allele frequency of 4.6 x 10-5 (1 in 10,799, less than one tenth that of BRCA1)and of PALB2-like risk (odds ratio = 5.0) down to a population minor allele frequency of 2.8 x 10-4 (1 in 1,779, less than half that of PALB2). Power was lower for identification of novel moderate penetrance genes (odds ratio = 2-3) like CHEK2 and ATM. CONCLUSIONS This is the largest case-control whole-exome analysis of enriched breast cancer published to date. Whilst additional breast cancer susceptibility genes likely exist, those of high penetrance are likely to be of very low mutational frequency. Contention exists regarding the clinical utility of such genes.

Abstract
Introduction Forensic mental health services provide care to people in secure psychiatric hospitals and specialised community teams. Measuring outcomes is important to ensure such services perform optimally, however existing measures are not sufficiently comprehensive and are rarely patient reported. Objectives To examine a novel instrument for measuring outcomes in forensic mental health services, the FORensic oUtsome Measure (FORUM), which consists of a complementary patient reported questionnaire (FORUM-P) and clinician reported questionnaire (FORUM-C). Methods Inpatients at a forensic psychiatric service based in a regional healthcare organization in the UK completed the FORUM-P, while members of their clinical teams completed the FORUM-C. Patients and clinicians also provided feedback on the questionnaires. Results Sixty-two patients participated with a mean age of 41.0 years (standard deviation 11.3). For internal consistency, Cronbach’s alpha for the FORUM-P was 0.87 (95% confidence interval (CI) 0.80-0.93) and for the FORUM-C was 0.93 (95% CI 0.91-0.96). For test-retest reliability the weighted kappa for the FORUM-P was 0.44 (95% CI 0.24-0.63) and for the FORUM-C was 0.78 (95% CI 0.73-0.85). For interrater reliability of the FORUM-C the Spearman correlation coefficient was 0.47 (95% CI 0.18-0.69). The FORUM-P received an average rating of 4.0 out of 5 for comprehensiveness, 4.6 for ease of use and 3.9 for relevance, while the FORUM-C received 4.1 for comprehensiveness, 4.5 for ease of use and 4.3 for relevance. Conclusions Outcome measures in forensic mental health can be developed with good measures of reliability and validity, and can be introduced into services to monitor patient progress. Disclosure No significant relationships.

Abstract
OBJECTIVE The objective of this review was to synthesize evidence on the experiences of faculty and staff nurses working with nursing students in clinical placement in residential aged care facilities. INTRODUCTION Nursing education helps prepare students to provide quality care to older adults. Nursing programs across the globe are championing the integration of content on the care of older adults into their curricula as well as recognizing the value of clinical placements that focus exclusively on this population. Staff nurses who work in residential aged care facilities often work alongside students. In this role, they can support faculty and mentor students. This review explored faculty and staff experiences of nursing student placements in such facilities. INCLUSION CRITERIA This review considered qualitative studies that address the experiences of faculty and staff nurses working with nursing students in residential aged care facilities. Studies published in English from 1995 onward were included. METHODS The literature search was conducted in CINAHL, MEDLINE, Embase, and ERIC. The search for unpublished articles included Proquest Dissertations and Theses and Google searches of the Canadian Nurses Association and American Nurses Association websites. Papers were screened by two reviewers independently against the inclusion criteria. Those meeting the criteria were appraised using the JBI critical appraisal checklist for qualitative research. Key findings from included studies were extracted using a standardized tool and classified as unequivocal, credible, or not supported. This review followed the principles of meta-aggregration in line with the JBI approach. RESULTS Six studies, published between 2001 and 2017, were included in the review. A total of 32 findings were extracted and aggregated into nine categories. From the nine categories, four synthesized findings were developed: i) students enhance the environment, whereby faculty and staff perceive that student presence enhances the residential aged care work and living environment, ii) effort is required by faculty and staff to make the experience work, reflecting a need for faculty and staff to accept and work with negativities, iii) residential aged care facilities provide rich learning experiences, indicating an appreciation for available learning opportunities, and iv) importance of a residential aged care-academic partnership for a collaborative approach in creating positive experiences for faculty and staff working with students in this setting. CONCLUSION Faculty and staff experiences highlight that residential aged care has the potential to provide students with valuable learning experiences, including how to provide comprehensive and quality nursing care to older adults. A lack of resources in residential aged care inspires faculty and staff to be creative in how they work with students. However, working with students can be challenging for faculty who lack interest and expertise in caring for older adults in this setting. Additionally, staff can become frustrated when they perceive that students do not value the learning opportunities that are available or do not appreciate the expertise required to work with older adults. Partnerships between residential aged care facilities and academic programs can ensure that faculty and staff have the support and resources required to optimize the clinical placements for students.

Abstract
OBJECTIVES Bacteremia is a serious and potentially lethal condition. Staphylococcus aureus is a leading cause of bacteremia and methicillin-resistant S. aureus (MRSA) accounts for more than a third of the cases. Compared to methicillin-sensitive S. aureus, MRSA is more than twice as likely to be fatal. Furthermore, subpopulations of seemingly isogenic bacteria may exhibit a range of susceptibilities, often called heterogenous resistance. These heterogeneous antibiotic-resistant infections are often misdiagnosed as hospital-acquired secondary infections because there are no clinically used tests that can differentiate between homogeneous and heterogeneous antibiotic resistance. We describe the development and proof of concept of rapid bacterial identification using photoacoustic flow cytometry and labeled bacteriophages with the characterization and differentiation of heterogeneous antibiotic-resistant bacterial infections. METHODS In photoacoustic flow cytometry, pulsed laser light is delivered to a sample flowing past a focused transducer and particles that absorb laser light create an acoustic response. Optically labeled bacteriophage are added to a bacterial mixture that flows through the photoacoustic chamber. The presence of target bacteria is determined by bound labeled phage which are detected photoacoustically. Incubation of bacterial samples in the presence and absence of the antibiotic daptomycin creates a difference in bacterial cell numbers that is quantified using photoacoustic flow cytometry. RESULTS Four clinical isolates were tested in the presence and absence of daptomycin. Photoacoustic events for each isolate were recorded and compared to growth curves. Samples treated with daptomycin fell into three categories: resistant, susceptible, and heterogeneous resistant. CONCLUSIONS Here we show a method to determine the presence of bacteria as a marker for bloodstream infection level and antibiotic sensitivity in less than 4 hours. Additionally, these results show an ability to identify heterogeneous resistant strains that are often misidentified.

Abstract
Abstract
Background
Patient reported outcome measures (PROMs) are increasingly recognised as a measure of treatment efficacy in randomised controlled trials (RCTs). It can be difficult to determine meaningful target differences in PROM scores for sample size calculations and this can risk over-recruitment and/or erroneous trial conclusions. The Difference ELicitation in TriAls (DELTA2) statement sets recommendations for sample size calculations in RCTs including target difference determination. We aimed to evaluate sample size calculations from high-profile surgical RCTs that used PROMs as their primary outcome, against DELTA2 standards, with a focus on target differences.
Method
Pubmed was systematically searched for surgical RCTs published in the five highest ranking journals, by Thomson Reuters impact factor, for medicine and surgery. Studies were included if surgery was the intervention and/or comparator arm, and a PROM was the primary outcome. Surgery was defined as using instrumentation to change macro-anatomy with the aim of improving health. Data were extracted with a piloted data collection sheet that included the DELTA2 reporting recommendations.
Results
Most target differences used in sample size calculations were determined with suboptimal techniques and target difference justification was overall poor. In this sample, £28 million of UK public research spending supported trials with poor target difference justification.
Conclusions
In this sample of trials, sample size calculations were generally not reported to DELTA2 standards. There was frequent use of sub-optimal methods to determine the target difference. This risks over-recruitment and/or erroneous trial conclusions. Clinicians should be aware of these potential pitfalls when interpreting published trials.

Abstract
Abstract
Aim
Delirium is an acute change in cognition and associated with adverse patient outcomes. The incidence of post-operative delirium after elective non-cardiac surgery is unknown. We aimed to assess the incidence of post-operative delirium in this group and the effect on patient outcomes.
Method
Patients aged 65 and over who underwent elective non-cardiac surgery were identified on post-operative day three. Delirium screening was performed in real time using the validated 4-AT assessment tool. A retrospective review of the patients’ preoperative and perioperative record was conducted to collect demographics and identify risk factors for delirium. Outcome data was collected at 30 days. Patients with a positive delirium score (>4) underwent a more in-depth assessment and managing teams given a delirium management pack.
Results
75 (39 male) consecutive patients were screened over a period of 4 months. Median age 77 years and 18% had frailty assessed as “vulnerable”. The majority of patients (37.3%) underwent thoracic surgery, followed by hepatobiliary (17.3%), gynaecological (17.3%), colorectal (12%), maxillofacial (9.3%) and ENT (4%). 5.3% (4) of patients had a positive 4-AT screen. No patients had a formal delirium screen or diagnosis in the initial 48 hours. The median length of stay for patients with a positive screen was 8.5 days (IQR 7.5-12) compared to 8 days (IQR 5-13) for patients with a negative screen.
Conclusions
Reassuringly, rate of post-operative delirium following elective operations in our Trust are low (5%). Larger numbers of patients are required to assess the impact this has on patient outcomes and identify correlation with risk factors.

Abstract
Abstract
Introduction
Secondary analysis of outcomes after 11,085 hip fracture operations from the prospective UK Anaesthesia Sprint Audit of Practice (ASAP 2) found an association between reduced intraoperative systolic arterial pressure (SAP) and postoperative mortality at five and 30 days. We sought to determine the incidence of hypotension in the postoperative period, rather than just intraoperatively, in a small sample of patients with fractured neck of femur.
Method
We performed a retrospective review of the notes, electronic vital signs and electronic general practice records from 40 patients with fractured neck of femur. We identified the latest SAP performed at their general practice (if done within one year before admission). We noted the pre-operative baseline SAP reading from the ward as well as the lowest SAP during several time periods: the pre-operative period; the fracture surgery; the recovery room; and during each 24-h period postoperatively until the fifth postoperative day.
Results
A SAP recording from general practice within the previous year was only accessible in 21 (53%) of patients, but where it was accessible, it was within 20% of the immediate preoperative SAP in 14 (66%) of patients. The incidence of relative hypotension (< 80% preoperative SAP) was 54% in the operating theatre, 41% in the recovery room, 65% on the ward during the remainder of the first postoperative 24 h, 55% during postoperative day 2, 53% during day 3, 33% during day 4 and 41% during day 5.
Conclusions
Postoperative hypotension was common in our sample. In our analysis, the highest incidence was on the ward during the first 24 hours postoperatively. However, 41% of patients still had hypotension 5 days postoperatively.

Abstract
Food systems are significant sources of global greenhouse gas emissions (GHGE). Since emission intensity varies greatly between different foods, changing food choices towards those with lower GHGE could make an important contribution to mitigating climate change. Public engagement events offer an opportunity to communicate these multifaceted issues and raise awareness about the climate change impact of food choices. An interdisciplinary team of researchers was preparing food and climate change educational activities for summer 2020. However, the COVID-19 pandemic and lockdown disrupted these plans. In this paper, we report on shifting these events online over the month of June 2020. We discuss what we did and the reception to our online programme. We then reflect on and highlight issues that arose. These relate to: (1) the power dynamics of children, diet and climate change; (2) mental health, diet and COVID-19; (3) engaging the wider science, agriculture and food communities; (4) the benefits of being unfunded and the homemade nature of this programme; (5) the food system, STEAM (science, technology, engineering, arts and mathematics) and diversity; and (6) how our work fits into our ongoing journey of food and climate change education.

Abstract
OBJECTIVE The purpose of this scoping review was to examine teaching strategies and activities used in nursing students' clinical placement in residential aged care facilities. INTRODUCTION Population aging necessitates that nursing curricula ensure student interest and commitment to working with older adults. While searching for suitable clinical placements that provide students with opportunities to care for older adults, nursing programs have turned to residential aged care facilities. Studies show that carefully planned placement in these environments supports students' needs and offers rich learning possibilities. INCLUSION CRITERIA This review examined intentional teaching strategies and activities used during student placement in residential aged care facilities, and considered research and textual papers on the subject. The strategies and activities included those that took place prior to, during, or after the experience. METHODS The review included qualitative and quantitative research reports as well as text and opinion papers. Only research reports and papers published in English from 1992 to August 2019 were included. The databases searched were: CINAHL (EBSCO), MEDLINE (Ovid), Academic Search Premier (EBSCO), Embase (Elsevier), ERIC (EBSCO), ProQuest Dissertations and Theses, and Google (with advanced search strategies). Two independent reviewers screened citations for inclusion while a third reviewer resolved discrepancies. A table was developed for data extraction to record data relating to the review objective. Specific data extracted included the details on research design, geographical location, year of publication, description of the teaching strategy or activity. RESULTS Of the 84 research reports and papers that were eligible for full-text review, only 25 (30%) were included in the final set. Sixteen papers were research reports including a variety of qualitative, quantitative, and mixed method designs. The remaining nine were textual papers and included frameworks, descriptions, and evaluations of a teaching strategy or activity. Most research reports and papers identified more than one strategy and/or activity used concurrently. The use of care staff as student mentors and facility orientation for students were the two most common strategies and activities reported. CONCLUSION A range of teaching approaches during clinical placements in residential aged care facilities was revealed. These approaches targeted students, staff of aged care facilities, and nursing faculty. Collaborative efforts between aged care facilities and educational institutions allowed for the pooling of resources and the delivery of teaching approaches to students and the engagement of care staff. Many of the approaches were co-designed by educational programs and residential aged care facilities. The number of approaches that used more than one teaching strategy and/or activity reflects an appreciation for the importance of student placements and the complexities of aged care facilities. A lack of longitudinal or evaluative research highlights a gap in the literature. There is a need for further work to understand and evaluate the long-term effects and benefits of teaching strategies and activities used to enhance students' clinical placements in resident aged care facilities.

Abstract
BACKGROUND To fully characterize the risk for dementia associated with cigarette smoking, studies must consider competing risks that hinder the observation of dementia or modify the chance that dementia occurs (i.e., death). Extant research examining the competing risks fails to account for the occurrence of death following dementia, limiting our understanding of the relation between smoking and dementia. OBJECTIVE Examine the impact of smoking status, lifetime smoking exposure, and duration of abstinence on incident dementia, death following dementia, and death without dementia. METHODS Multi-state models estimated hazard ratios (HR) for 95% confidence interval (CI) of 10,681 cognitively healthy adults for transition from baseline to dementia, baseline to death, and dementia to death based on smoking status, lifetime cigarette exposure, and abstinence duration. RESULTS Compared to never smokers, current smokers had increased risk of dementia (HR = 1.66; 95% CI 1.18- 2.32; p = 0.004), and death from baseline (HR = 2.98; 95% CI 2.24- 3.98; p < 0.001) and incident dementia (HR = 1.88; 95% CI 1.08- 3.27; p = 0.03). Pack years increased risk of death from baseline (HR = 1.01; 95% CI 1.00- 1.01; p < 0.001), but not dementia risk (HR = 1.00; 95% CI 1.00- 1.00; p = 0.78) or death following dementia (HR = 1.01; 95% CI 1.00- 1.01; p = 0.05). Recent quitters (quit < 10 years), compared to never smokers, had increased risk of death after baseline (HR = 2.31; 95% CI 1.55- 3.43; p < 0.001), but not dementia (HR = 1.17; 95% CI 0.73- 1.88; p = 0.52) or death following dementia (HR = 1.01; 95% CI 0.42- 2.41; p = 0.99). CONCLUSION Current smoking increases the risk for dementia and death, but dementia is better attributed to smoking recency than lifetime exposure. Smoking cessation at any age might reduce these risks for cognitively healthy individuals.

Abstract
The aim of the study was to analyze sleep duration and behaviors in relation to psychological parameters in children and adolescents with obesity seeking inpatient weight-loss treatment in comparison to normal-weight children, and whether or not these variables would improve during the time course of treatment. Sixty children or adolescents with overweight and obesity (OBE) and 27 normal-weight (NW) peers (age: 9-17) were assessed for subjective sleep measures through self-reported and parent-reported questionnaires, as well as body weight, body composition, and psychological questionnaires. The OBE participants were assessed upon admission and before discharge of an inpatient multidisciplinary weight-loss program. NW participants' data were collected for cross-sectional comparison. In comparison to NW, children and adolescents with OBE had a shorter self-reported sleep duration and had poorer sleep behaviors and more sleep-disordered breathing as reported by their parents. No change in sleep measures occurred during the inpatient treatment. Psychological factors including higher anxiety, depression, and destructive-anger-related emotion regulation were moderate predictors for unfavorable sleep outcomes, independent of weight status. Children with obesity had less favorable sleep patterns, and psychological factors influenced sleep in children, independent of weight. More research is needed on the relationship and direction of influence between sleep, psychological factors, and obesity, and whether they can be integrated in the prevention and management of childhood obesity and possibly also other pediatric diseases.

Abstract
The development of a novel rapid dual energy X-ray absorptiometry (DEXA) system provides the opportunity to improve measurement of beef carcase composition. A prototype rapid DEXA system was built in a shipping container to scan 51 beef carcases selected for a wide range in weight and fatness. One side of each carcase was spray chilled and the other conventionally chilled overnight before being quartered for DEXA scanning and then being cut into 16 pieces for CT scanning to determine carcase composition. Spray chilling did not impact DEXA prediction of CT composition, with the DEXA system describing 89%, 95%, and 87% of the variation in beef carcase CT lean %, fat % and bone %, with a root mean square error of prediction of 2.31 lean %, 2.15 fat %, and 1.12 bone % units. These results demonstrate that the novel rapid DEXA system has excellent capacity to predict CT composition in beef carcases.

Abstract
Many lysosome functions are determined by a lumenal pH of ∼5.0, including the activity of resident acid-activated hydrolases. Lysosome pH (pHlys) is often increased in neurodegenerative disorders and predicted to be decreased in cancers, making it a potential target for therapeutics to limit the progression of these diseases. Accurately measuring pHlys, however, is limited by currently used dyes that accumulate in multiple intracellular compartments and cannot be propagated in clonal cells for longitudinal studies or used for in vivo determinations. To resolve this limitation, we developed a genetically encoded ratiometric pHlys biosensor, pHLARE (pHLysosomal Activity REporter), which localizes predominantly in lysosomes, has a dynamic range of pH 4.0 to 6.5, and can be stably expressed in cells. Using pHLARE we show decreased pHlys with inhibiting activity of the mammalian target of rapamycin complex 1 (mTORC1). Also, cancer cells from different tissue origins have a lower pHlys than untransformed cells, and stably expressing oncogenic RasV12 in untransformed cells is sufficient to decrease pHlys. pHLARE is a new tool to accurately measure pHlys for improved understanding of lysosome dynamics, which is increasingly considered a therapeutic target.

Abstract
Osteoclasts (OCs) and much less dendritic cells (DCs) induce significant expansion and functional activation of NK cells, and furthermore, the OC-expanded NK cells preferentially increase the expansion and activation of CD8+ T cells by targeting CD4+ T cells. When autologous OCs were used to expand patient NK cells much lower percentages of expanded CD8+ T cells, decreased numbers of expanded NK cells and decreased functions of NK cells could be observed, and the addition of allogeneic healthy OCs increased the patients' NK function. Mechanistically, OC-expanded NK cells were found to lyse CD4+ T cells but not CD8+ T cells suggesting potential selection of CD8+ T cells before their expansion by OC activated NK cells. In agreement, Increased IFN-γ secretion, and NK cell-mediated cytotoxicity and higher percentages of CD8+ T cells, in various tissue compartments of oral tumor-bearing hu-BLT mice in response to immunotherapy by OC-expanded NK cells were observed. Thus, our results indicate an important relationship between NK and CD8+ T cells.

Abstract
OBJECTIVE Safe vehicle speeds were identified as a key element in a safe system approach to road safety. The City of Yarra in Melbourne, Australia has a 40 km/h default speed limit across their municipality, but wished to reduce the speed limit in local residential streets to 30 km/h. The Monash University Accident Research Center provided Council with a design for a demonstration trial and agreed to evaluate its safety benefits over 12 months. The trial was expected to show significant reductions in speed and increased community support. METHOD A before and after design was employed with a control (untreated) area to evaluate the safety outcomes of the trial. Speed limits were reduced to 30 km/h in the trial area for 12 months but kept at kept at the current 40 km/h (25 mph) limit in the control region. Vehicle speeds were measured at around 100 selected sites in the trial and control areas, and resident surveys were undertaken in both regions before and after the trial. RESULTS The findings showed a small but modest reduction of 1.1% in average speed in the trial region but a surprising 2.7% in the control region. On further examination, significant reductions were observed in the percent of vehicles exceeding 40 km/h (25 mph) and 50 km/h (31 mph) in both the treated and control regions, but not at 30 km/h (19 mph). A regression analysis further showed a significant treatment effect of 11% at 40 km/h and 25% at 50 km/h when adjusting for differences between treated and controls. Among other findings, the survey results found increased support for the lower speed limit of 17% with little adverse consequences. CONCLUSION The findings give support for the likely safety benefits of the 30 km/h trial with increased support from the residents. Speed reductions in the control region suggested a carry-over of the effects of the trial but also added support by local residents for reduced speed limits in the region. Potential injury savings were estimated at a 4% reduction in the risk of a pedestrian injury from the observed treatment effect in the trial region.

Abstract
Legacy building interventions like plaster hand molds are offered in most children's hospitals, yet little is known about how the concept of legacy is understood and described by pediatric health care providers. Therefore, this study explored pediatric health care providers' perceptions of legacy at an academic medical center to ensure that future legacy interventions are evidence-informed and theoretically grounded. An electronic survey featuring three open-ended questions and two multiple-choice questions with an option for free text response was completed by 172 medical and psychosocial health care providers. Analysis yielded four themes: (1) legacy is intergenerational, enduring, and typically associated with end-of-life; (2) legacies articulate the impacts on others for which one is known and remembered; (3) legacies can be expressed through tangible items or intangible qualities; and (4) legacies are informed and generated by family relationships and work experiences. By understanding legacy as a personally and professionally contextualized experience, health care providers can better assess and meet the legacy needs of hospitalized pediatric patients and families.

OBJECTIVE The objective of this review is to synthesize evidence on the experiences and perceptions of faculty and staff nurses toward nursing students' clinical placements in residential aged care facilities. INTRODUCTION Nursing education plays an important role in preparing students to provide quality care to older adults. Recent reports suggest that nursing programs across the globe are championing the integration of content on the care of older adults into their curricula as well as recognizing the value of clinical placements that focus exclusively on care for older adults, such as in residential aged care facilities. Student experiences in residential aged care facilities can play a significant role in helping shape professional identity as well as how the setting is viewed. Student interactions with nursing faculty and staff in the residential care learning environment are both recognized as being influential in this process. This review seeks to explore faculty and staff experiences and perceptions of nursing student placements in such facilities. INCLUSION CRITERIA This review will consider qualitative studies that address the experiences and perceptions of faculty and staff nurses who work with nursing students in residential aged care facilities. Studies published in English and from 1995 onward will be sought. METHODS Two reviewers will independently appraise studies and extract qualitative data using the JBI standardized critical appraisal and extraction instruments. Findings from the review will be categorized according to similarity in meaning, and categories subjected to a meta-synthesis to produce a single comprehensive set of synthesized findings.

Abstract
OBJECTIVE The objective of this scoping review is to examine and map current knowledge of teaching strategies and activities used with nursing students during clinical placements in residential aged care facilities. INTRODUCTION Residential aged care facilities provide opportunities for nursing students to develop skills and interest in caring for older adults. Studies that address students' clinical placements in these settings highlight the benefits of and concerns with their experiences. Insight into the state of knowledge regarding teaching strategies used in residential aged care facilities could benefit nursing education programs and help to ensure student learning is maximized. INCLUSION CRITERIA This scoping review will consider research and narrative reports on teaching activities and strategies used by nursing faculty and residential aged care facility staff in teaching nursing students. The concepts of interest include planned and intentional activities and strategies used to facilitate student learning and student clinical experiences. A clinical experience is defined as when a student enters a residential aged care facility and is assigned an individual or individuals to care for. METHODS This scoping review will aim to locate published and unpublished literature employing a three-step search strategy. Only papers published in English from 1992 onward will be included. Data extracted from eligible papers will include details on the participants, context, strategy, activity and outcomes. Extracted data will be reported in a tabular form and presented narratively to address the review objective.

Abstract
The gastrointestinal (GI) microbiota plays an important role in health and disease, including brain function and behavior. Bariatric surgery (BS) has been reported to result in various changes in the GI microbiota, therefore demanding the investigation of the impact of GI microbiota on treatment success. The goal of this systematic review was to assess the effects of BS on the microbiota composition in humans and other vertebrates, whether probiotics influence postoperative health, and whether microbiota and psychological and behavioral factors interact. A search was conducted using PubMed and Web of Science to find relevant studies with respect to the GI microbiota and probiotics after BS, and later screened for psychological and behavioral parameters. Studies were classified into groups and subgroups to provide a clear overview of the outcomes. Microbiota changes were further assessed for whether they were specific to BS in humans through the comparison to sham operated controls in other vertebrate studies. Changes in alpha diversity appear not to be specific, whereas dissimilarity in overall microbial community structure, and increases in the abundance of the phylum Proteobacteria and Akkermansia spp. within the phylum Verrucomicrobia after surgery were observed in both human and other vertebrates studies and may be specific to BS in humans. Human probiotic studies differed regarding probiotic strains and dosages, however it appeared that probiotic interventions were not superior to a placebo for quality of life scores or weight loss after BS. The relationship between GI microbiota and psychological diseases in this context is unclear due to insufficient available data.

Abstract
OBJECTIVE This study aimed to (a) validate the factor structure for a measure of peer conflict in youth with type 1 diabetes (T1D); (b) determine empirical patterns of peer conflict in terms of context (friend vs. nonfriend) and content (diabetes-specific vs. general) within a broader context of socio-demographic factors; and (c) examine how these patterns and socio-demographic factors relate to adolescents' T1D adherence, quality of life, and glycemic control (HbA1c). METHODS Youth with T1D (N = 178), ages 12-18, reported demographic variables, illness duration, adherence, quality of life, and peer conflict. HbA1c was extracted from medical records. Confirmatory factor analysis validated a factor structure for the Diabetes Peer Conflict Scale (DPCS) and latent profile analysis (LPA) determined profiles of peer conflict. RESULTS A four-factor structure emerged for the DPCS: general friend conflict, general nonfriend conflict, T1D friend conflict, and T1D nonfriend conflict. Using these factors as indicators in LPA, four profiles were confirmed: (a) Low Overall Conflict (LOC) and (b) Moderate Overall Conflict (MOC), (c) a Nonfriend Conflict (NFC), and (d) a Friend Conflict (FC) profile. Differences were not identified between diabetes specific versus general conflict. Socio-demographic variables did not predict class membership. The LOC profile reported the highest quality of life and best glycemic control, whereas the FC profile reported the lowest adherence behaviors. Conclusions: Peer conflict uniquely contributes to diabetes adaptation above and beyond socio-demographic and illness factors.

Abstract
BACKGROUND Individuals with spina bifida are at increased risk for urinary tract infection (UTI), however there are few population-based investigations of the burden of UTI hospitalizations. OBJECTIVE We assessed rates and risk factors for UTI hospitalization in individuals with and without spina bifida. METHODS We conducted a retrospective cohort study to estimate rates of UTI hospitalization by spina bifida status. We included individuals enrolled in Tennessee Medicaid who lived in one of the Emerging Infections Program's Active Bacterial Surveillance counties between 2005 and 2013. Spina bifida was primarily defined and UTI hospitalizations were identified using International Classification of Diseases, Ninth Revision diagnoses. We also studied a subset without specific health conditions potentially associated with UTI. We used Poisson regression to calculate rate ratios (RR) of UTIs for individuals with versus without spina bifida, adjusting for race, sex and age group. RESULTS Over the 9-years, 1,239,362 individuals were included and 2,493 met criteria for spina bifida. Individuals with spina bifida had over a four-fold increased rate of UTI hospitalization than those without spina bifida-in the overall study population and in the subset without specific, high-risk conditions (adjusted rate ratios: 4.41, 95% confidence intervals: 3.03, 6.43) and (4.87, 95% CI: 2.99, 7.92), respectively. We detected differences in rates of UTI hospitalization by race and sex in individuals without spina bifida that were not seen among individuals with spina bifida. CONCLUSIONS Individuals with spina bifida had increased rates of UTI hospitalizations, and associated demographic patterns differed from those without spina bifida.

Abstract
Abstract: Background and Aims: We have previously demonstrated that the stage of differentiation of tumors has profound effect on the function of NK cells, and that stem-like/poorly differentiated tumors were preferentially targeted by the NK cells. Therefore, in this study we determined the role of super-charged NK cells in immune mobilization, lysis, and differentiation of stem-like/undifferentiated tumors implanted in the pancreas of humanized-BLT (hu-BLT) mice fed with or without AJ2 probiotics. The phenotype, growth rate and metastatic potential of pancreatic tumors differentiated by the NK cells (NK-differentiated) or patient derived differentiated or stem-like/undifferentiated pancreatic tumors were investigated. Methods: Pancreatic tumor implantation was performed in NSG and hu-BLT mice. Stage of differentiation of tumors was determined using our published criteria for well-differentiated tumors exhibiting higher surface expression of MHC- class I, CD54, and PD-L1 (B7H1) and lower expression of CD44 receptors. The inverse was seen for poorly-differentiated tumors. Results: Stem-like/undifferentiated pancreatic tumors grew rapidly and formed large tumors and exhibited lower expression of above-mentioned differentiation antigens in the pancreas of NSG and hu-BLT mice. Unlike stem-like/undifferentiated tumors, NK-differentiated MP2 (MiaPaCa-2) tumors or patient-derived differentiated tumors were not able to grow or grew smaller tumors, and were unable to metastasize in NSG or hu-BLT mice, and they were susceptible to chemotherapeutic drugs. Stem-like/undifferentiated pancreatic tumors implanted in the pancreas of hu-BLT mice and injected with super-charged NK cells formed much smaller tumors, proliferated less, and exhibited differentiated phenotype. When differentiation of stem-like tumors by the NK cells was prevented by the addition of antibodies to IFN-γ and TNF-α, tumors grew rapidly and metastasized, and they remained resistant to chemotherapeutic drugs. Greater numbers of immune cells infiltrated the tumors of NK-injected and AJ2-probiotic bacteria-fed mice. Moreover, increased IFN-γ secretion in the presence of decreased IL-6 was seen in tumors resected and cultured from NK-injected and AJ2 fed mice. Tumor-induced decreases in NK cytotoxicity and IFN-γ secretion were restored/increased within PBMCs, spleen, and bone marrow when mice received NK cells and were fed with AJ2. Conclusion: NK cells prevent growth of pancreatic tumors through lysis and differentiation, thereby curtailing the growth and metastatic potential of stem-like/undifferentiated-tumors.

Abstract
BACKGROUND AND OBJECTIVES Negative consequences of tobacco use during cancer treatment are well-documented but more in-depth, patient-level data are needed to understand patient beliefs about continued smoking (vs cessation) during gastrointestinal (GI) cancer treatment. METHODS We conducted semi-structured interviews with 10 patients who were active smokers being treated for GI cancers and 5 caregivers of such patients. All interviews were audio-recorded, transcribed verbatim, and uploaded to NVivo. We consensus coded data inductively using conventional content analysis and iteratively developed our codebook. We developed data matrices to categorize the themes regarding patient perspectives on smoking as well as presumed barriers to smoking cessation during active therapy. RESULTS Our interviews revealed three consistent themes: (a) Smoking cessation is not necessarily desired by many patients who have received a cancer diagnosis; (b) Failure in past quit attempts may lead to feelings of hopeless about future attempts, especially during cancer treatment; (c) Patients perceived little to no access to smoking cessation treatment at the time of their cancer diagnosis. CONCLUSIONS Well-designed systemic changes that promote the positive and efficacious effects of quitting smoking during cancer treatment, and that provide barrier-free access to such treatments may be helpful in promoting tobacco-free behavior during cancer treatment.

Abstract
Research on the efficacy, effectiveness, and dissemination potential of behavioral activation (BA)-focused interventions for depression and comorbid disorders has expanded rapidly. However, research that examines how BA interventions work has seen less growth. A primary purported mechanism of BA is activation, which reflects a person's meaningful (re)engagement in life. BA theory posits that depression will decrease as activation increases, and that changes in the mechanism variable will lead to changes in outcome. The current study aims to investigate activation as a potential mechanism of change in the context of a BA-focused residential treatment intervention for mood problems using repeated measures of self-reported activation and depression from a large comorbid sample (N = 578). Growth curve modeling was used to examine between-person differences in within-person change over time. Findings suggest that self-reported activation increases and depression decreases over time. Moreover, results show both linear and quadratic growth and that the rate of change in activation predicts the rate of change of depression. BA-focused residential treatment may facilitate activation, which exerts an effect on depression among residents with diagnostically complex presentations.
