    Abstract Patients with end-stage kidney disease (ESKD) have a high symptom-burden and high rates of morbidity and mortality. Despite this, evidence has shown that this patient group does not have timely discussions to plan for deterioration and death, and at the end of life there are unmet palliative care needs. Advance care planning is a process that can help patients share their personal values and preferences for their future care and prepare for declining health. Earlier, more integrated and holistic advance care planning has the potential to improve access to care services, communication, and preparedness for future decision-making and changing circumstances. However, there are many barriers to successful implementation of advance care planning in this population. In this narrative review we discuss the current evidence for advance care planning in patients on dialysis, the data around the barriers to advance care planning implementation, and interventions that have been trialled. The review explores whether the concepts and approaches to advance care planning in this population need to be updated to encompass current and future care. It suggests that a shift from a problem-orientated approach to a goal-orientated approach may lead to better engagement, with more patient-centred and satisfying outcomes.

    Abstract (1) Background: Long-term caregiving for patients receiving hemodialysis (HD), is associated with physical and psychological stress, which may impact on the well-being and quality of life of caregivers. Due to a lack of understanding of the experiences of informal caregivers of patients receiving HD, especially in Saudi Arabia, this study aimed to measure burden in informal caregivers of patients receiving HD, examine the factors that predict caregiver burden (CB), and explore the experience of burden in caregivers of patients receiving HD. (2) Methods: This study used a mixed-methods, sequential, explanatory design, which consisted of two phases. Phase 1 involved a cross-sectional study design, with a convenience sample of 61 caregivers of patients on maintenance HD for at least 3 months. All caregivers in the study completed the Arabic version of the Zarit Burden Interview to identify caregiver burden. Phase 2 of the study involved a qualitative descriptive design involving semi-structured interviews with nine caregivers. (3) Results: Study findings indicate that caregivers did not experience severe burden. Being older, a female caregiver and having comorbidities was positively associated with increased levels of caregiver burden. In the qualitative phase of the study, a number of important factors emerged that may contribute to a reduction in caregiver burden, including social support, cultural acceptance, and religious influences. (4) Conclusion and impact: CB was found to be low when a comparison was made with other studies using similar populations. Understanding the factors that influence caregiver burden will contribute to the accurate assessment of caregiver burden and help reduce burden in informal caregivers, patients with renal failure, and others with chronic illnesses worldwide.

    Abstract Armed conflicts have detrimental impacts on the environment, including land systems. The prevailing understanding of the relation between Land Use/Land Cover (LULC) and armed conflict fails to fully recognize the complexity of their dynamics - a shortcoming that could undermine food security and sustainable land/water resources management in conflict settings. The Syrian portion of the transboundary Orontes River Basin (ORB) has been a site of violent conflict since 2013. Correspondingly, the Lebanese and Turkish portions of the ORB have seen large influxes of refugees. A major challenge in any geoscientific investigation in this region, specifically the Syrian portion, is the unavailability of directly-measured "ground truth" data. To circumvent this problem, we develop a novel methodology that combines remote sensing products, machine learning techniques and quasi-experimental statistical analysis to better understand LULC changes in the ORB between 2004 and 2022. Through analysis of the resulting annual LULC maps, we can draw several quantitative conclusions. Cropland areas decreased by 21-24 % in Syria's conflict hotspot zones after 2013, whereas a 3.4-fold increase was detected in Lebanon. The development of refugee settlements was also tracked in Lebanon and on the Syrian/Turkish borders, revealing different LULC patterns that depend on settlement dynamics. The results highlight the importance of understanding the heterogenous spatio-temporal LULC changes in conflict-affected and refugee-hosting countries. The developed methodology is a flexible, cloud-based approach that can be applied to wide variety of LULC investigations related to conflict, policy and climate.

    Abstract Background: The label 'faller' and the associated stigma may reduce healthcare-seeking behaviours. However, falls are not inevitably progressive and many drivers are modifiable. This observational study described the 8-year longitudinal trajectories of self-reported falls in The Irish Longitudinal Study on Ageing (TILDA) and studied associations with factors, including mobility, cognition, orthostatic hypotension (OH), fear of falling (FOF) and use of antihypertensive and antidepressant medications.
    Methods: Participants aged ≥50 years at each wave were categorised by whether they averaged ≥2 falls in the previous year (recurrent fallers) or not (≤1 fall). Next-wave transition probabilities were estimated with multi-state models.
    Results: 8,157 (54.2% female) participants were included, of whom 586 reported ≥2 falls at Wave 1. Those reporting ≥2 falls in the past year had a 63% probability of moving to the more favourable state of ≤1 fall. Those reporting ≤1 fall had a 2% probability of transitioning to ≥2 falls. Besides older age and higher number of chronic conditions, factors that increased the risk of transitioning from ≤1 fall to ≥2 falls were lower Montreal Cognitive Assessment score, FOF and taking antidepressants. Conversely, male sex, higher timed up and go time, the presence of OH and being on antidepressants reduced the probability of improving from ≥2 falls to ≤1 fall.
    Conclusion: The majority of recurrent fallers experienced favourable transitions. Improvements in cognitive and psychological status, psychotropic prescribing, mobility and OH may help improve trajectories. Findings may help combat stigma associated with falling and promote preventative healthcare-seeking behaviours.

    Abstract Objectives: The aim of the study was to identify care home characteristics associated with reported care home influenza outbreaks and factors associated with increased transmission of influenza-like illness (ILI) in care homes in Cheshire and Merseyside during the 2017-2018 influenza season.
    Study design: This is a matched case-control study comparing characteristics between care homes with and without a declared influenza outbreak and a retrospective risk factor analysis of care home residents with ILI.
    Methods: Routinely collected outbreak surveillance data on symptomatic residents and staff, antiviral prophylaxis and influenza vaccination history, which were reported to Public Health England, were extracted from health protection electronic records. Further care home characteristics were extracted from the Care Quality Commission (CQC) website. Care homes with declared influenza outbreaks were matched with care homes without outbreaks. Chi-squared tests and logistic regression were used to examine associations between care home factors and ILI.
    Results: There were no significant differences in characteristics between 77 care homes with declared influenza outbreaks and 77 matched care homes without outbreaks. Of 2,744 residents from the homes with a declared outbreak, 644 (24%) developed an ILI. The care home risk factors were having a low CQC score and activation of antiviral prophylaxis and the protective factors were having higher numbers of residents, specializing in dementia care and having the highest CQC score. Significantly more cases occurred in residential homes than in nursing homes, in homes with lower CQC scores and in homes where eligible residents were given antiviral prophylaxis.
    Conclusions: In homes with declared outbreaks, certain characteristics including activation of antiviral prophylaxis were associated with an increased risk of ILI. Further research is needed, particularly focussing on temporality between provision of prophylactic antivirals and the onset of ILI.

    Abstract Importance: Transphobia and stigma remain barriers to seeking mental health care for gender-diverse adolescents.
    Objective: To examine the utility of brief social contact-based video interventions of transgender protagonists with depression to reduce transphobia and depression-related stigma and increase treatment-seeking intentions among adolescents in the general population.
    Design, setting, and participants: During August 2021, a total of 1437 participants were recruited and randomly assigned to 1 of 4 video-based conditions in a 2:2:1:1 ratio: (1) transgender adolescent girls, (2) transgender adolescent boys, (3) cisgender adolescent girls, or (4) cisgender adolescent boys.
    Interventions: In each of the approximately 110-second videos, an empowered presenter shared their personal story about coping with depression and reaching out for help.
    Main outcomes and measures: The primary outcome was the score on the Attitudes Toward Transgender Men and Women (ATTMW) scale. Secondary outcomes were (1) a "gender thermometer" rating for warmth in transgender perception, (2) the Depression Stigma Scale (DSS) score, and (3) the General Health-Seeking Questionnaire (GHSQ) score.
    Results: Of the 1437 randomized participants, 1098 (76%) completed the postintervention assessment and passed all the validity tests (mean [SD] age, 16.9 [1.2] years; 481 [44%] male; 640 [58%] White). A significant change in attitudes toward transgender youth was found within the intervention group only (mean [SD] ATTMW scores: intervention group, 34.6 [23.1] at baseline to 32.8 [24.2] after intervention; P < .001; control group, 33.5 [23.4] at baseline to 32.4 [24.1] after intervention; P = .01). The mean (SD) total DSS scores decreased significantly across study groups (intervention: 1.3 [3.3]; control: 1.7 [3.3]; P < .001). A significant increase in intention to seek help from a parent was found in the intervention (mean [SD] GHSQ score, 0.2 [1.1]) and control (mean [SD] GHSQ score, 0.3 [1.2]) groups (P < .001), as was a decrease in those not wanting to seek help from anyone (mean [SD] GHSQ score: intervention, 0.2 [1.6], P = .009; control, 0.3 [1.2], P < .001) Secondary analyses revealed significant differences in baseline ATTMW scores and intervention effects between transgender and gender-diverse and cisgender participants and between lesbian, gay, bisexual, or queer (LGBQ) and straight participants (F = 36.7, P < .001) and heterosexual participants (F = 37.0, P < .001). A significant difference was also found in mean (SD) transgender warmth scores from baseline to after intervention between groups (2.6° [13.1°] in the intervention group vs 0.4° [8.3°] in the control group; P < .001).
    Conclusions and relevance: In this randomized clinical trial, brief social contact-based videos proved efficacious in reducing transphobia and depression-related stigma and in increasing treatment-seeking intentions among adolescents in the general population. By personifying, individualizing, and providing face and voice to the experience of transgender youth, other adolescents, especially those who are cisgender and/or of a heterosexual orientation, can gain empathetic insights into the lives of their often marginalized and stigmatized fellow youth.

    Abstract Introduction: Motivational interviewing (MI) proficiency may erode quickly, limiting its effectiveness. We examined whether health professionals completing a 2-day workshop, with 3 to 5 hours of personalized coaching, and twice-yearly group reflections sustained proficiency for the duration of a hip fracture rehabilitation trial and whether intervention was implemented as intended.
    Methods: A fidelity study was completed as part of a process evaluation of the trial that tested whether physical activity increased among hip fracture patients randomly allocated to receive MI (experimental) compared with dietary advice (control) over ten 30-minute sessions. Twelve health professionals (none were proficient in MI before trial commencement) delivered the intervention for up to 952 days. Two hundred experimental sessions (24% of all sessions, 83 patients) were randomly selected to evaluate proficiency using the MI Treatment Integrity scale; along with 20 control sessions delivered by four dietitians. Linear mixed-effects regression analyses determined whether proficiency was sustained over time. Dose was assessed from all experimental sessions (n = 840, 98 patients).
    Results: Intervention was implemented as intended; 82% of patients received at least eight 30-minute sessions. All motivational interviewers were proficient, whereas dietitians did not inadvertently deliver MI. Time had no effect on MI proficiency (est < 0.001/d, P = .913, 95% CI, -0.001 to 0.001).
    Discussion: MI proficiency was sustained in a large trial over 2.6 years by completing a 2-day workshop, 3 to 5 hours of personalized coaching, and twice-yearly group reflections, even for those without previous experience; further research needs to establish the maximum duration of training effectiveness.

    Abstract Background: The relationship between the donor-derived cell-free DNA fraction (dd-cfDNA[%]) in plasma in kidney transplant recipients at time of indication biopsy and gene expression in the biopsied allograft has not been defined.
    Methods: In the prospective, multicenter Trifecta study, we collected tissue from 300 biopsies from 289 kidney transplant recipients to compare genome-wide gene expression in biopsies with dd-cfDNA(%) in corresponding plasma samples drawn just before biopsy. Rejection was assessed with the microarray-based Molecular Microscope Diagnostic System using automatically assigned rejection archetypes and molecular report sign-outs, and histology assessments that followed Banff guidelines.
    Results: The median time of biopsy post-transplantation was 455 days (5 days to 32 years), with a case mix similar to that of previous studies: 180 (60%) no rejection, 89 (30%) antibody-mediated rejection (ABMR), and 31 (10%) T cell-mediated rejection (TCMR) and mixed. In genome-wide mRNA measurements, all 20 top probe sets correlating with dd-cfDNA(%) were previously annotated for association with ABMR and all types of rejection, either natural killer (NK) cell-expressed (
    Conclusions: The dd-cfDNA(%) at time of indication biopsy strongly correlates with active molecular rejection and has the potential to reduce unnecessary biopsies.
