Advocates for improved equity in kidney transplant in the US have recently focused efforts on initiatives to increase referral for transplant evaluation. However, because donor kidneys remain scarce, increased referrals are likely to result in an increasing number of patients proceeding through the evaluation process without ultimately receiving a kidney. Unfortunately, the process of referral and evaluation can be highly resource-intensive for patients, families, transplant programs, and payers. Patients and families may incur out-of-pocket expenses and be required to complete testing and treatments that they might not have chosen in the course of routine clinical care. Kidney transplant programs may struggle with insufficient capacity, inefficient workflow, and challenging programmatic finances and payers will need to absorb the increased expenses of upfront pretransplant costs. Increased referral in isolation may risk simply transmitting system stress and resulting disparities to downstream processes in this complex system. We argue that success in efforts to improve access through increased referrals hinges on adaptations to the pretransplant process more broadly. We call for an urgent reevaluation and redesign at multiple levels of the pretransplant system in order to achieve the aim of equitable access to kidney transplantation for all patients with kidney failure.

Governments globally are adapting to sea level rise through a range of interventions to improve everyday lives of communities at risk. One prominent response is planned relocation, where people and communities are enabled to move from localities exposed to coastal erosion and inundation as a result of sea level rise. Managed retreat has significant social consequences including under-reported impacts on health, well-being and social identity. Here we adopt well-established measures of well-being and document the outcomes of planned relocation on well-being in the Volta Delta region of Ghana. Data from a bespoke survey for individuals (n = 505) in relocated and non-relocated communities demonstrate that planned relocation negatively impacts well-being and anxiety of those relocated when compared to a community that is equally exposed but has not moved. Individuals in the relocated community reported significantly lower levels of overall wellbeing, significantly higher levels of anxiety, and lower perceptions of safety, compared to non-relocated community members. These outcomes are explained as being related to the disruption of community connection, identities, and feelings of efficacy. Relocated community members reported significantly lower levels of attachment to the local area and home, significantly lower levels of community-based self-efficacy, and significantly lower levels of overall community-based identity. The results demonstrate that planned relocation to address sea level rise has multiple social consequences with outcomes for well-being that are not straightforwardly related to risk reduction.

This study aimed to compare the efficacy of two pharmacological protocols for inducing ex copula ejaculation in donkeys. Seven healthy jacks (male donkeys) aged 4 to 20 years (median 8 years) and weighing 136.2±4.17 kg (mean±SE) were enrolled. Using a crossover design, each jack was subjected in a random order to two treatment protocols (IX and IDO) with an interval of 7 days between the two protocols. Each jack was orally administered 3 mg/kg imipramine hydrochloride followed 2 hours later by intravenous (IV) administration of 1.1 mg/kg xylazine hydrochloride (IX protocol) or 0.02 mg/kg detomidine hydrochloride and 20 IU total dose oxytocin (IDO protocol). The jacks were monitored for behavioral changes and ejaculation up to 3 hours from the beginning of each protocol. A total of 22 ex copula ejaculation replicates were attempted. Both protocols resulted in deep sedation and partial to complete penile protrusion in all jacks. There was no difference in the efficacy with the IX protocol inducing ejaculation in 1 of the 11 replicates and the IDO protocol inducing ejaculation in none of the 11 replicates. The results suggest that neither of the two tested pharmacological protocols were effective in inducing ex copula ejaculation in donkeys.

The cause of Alzheimer's disease (AD), and the pathophysiological mechanisms involved, remain major unanswered questions in medical science. Oral bacteria, especially those species associated with chronic periodontitis and particularly Porphyromonas gingivalis, are being linked causally to AD pathophysiology in a subpopulation of susceptible individuals. P. gingivalis produces large amounts of proteolytic enzymes, haem and iron capture proteins, adhesins and internalins that are secreted and attached to the cell surface and concentrated onto outer membrane vesicles (OMVs). These enzymes and adhesive proteins have been shown to cause host tissue damage and stimulate inflammatory responses. The ecological and pathophysiological roles of P. gingivalis OMVs, their ability to disperse widely throughout the host and deliver functional proteins lead to the proposal that they may be the link between a P. gingivalis focal infection in the subgingivae during periodontitis and neurodegeneration in AD. P. gingivalis OMVs can cross the blood brain barrier and may accelerate AD-specific neuropathology by increasing neuroinflammation, plaque/tangle formation and dysregulation of iron homeostasis, thereby inducing ferroptosis leading to neuronal death and neurodegeneration.

Advocacy and policy change are powerful levers to improve quality of care and better support patients on home dialysis. While the kidney community increasingly recognizes the value of home dialysis as an option for patients who prioritize independence and flexibility, only a minority of patients dialyze at home in the United States. Complex system-level factors have restricted further growth in home dialysis modalities, including limited infrastructure, insufficient staff for patient education and training, patient-specific barriers, and suboptimal physician expertise. In this article, we outline trends in home dialysis use, review our evolving understanding of what constitutes high-quality care for the home dialysis population (as well as how this can be measured), and discuss policy and advocacy efforts that continue to shape the care of US patients and compare them with experiences in other countries. We conclude by discussing future directions for quality and advocacy efforts.

The Arg-specific gingipains of Porphyromonas gingivalis RgpA and RgpB have 97% identical sequences in their catalytic domains yet their propeptides are only 76% identical. RgpA isolates as a proteinase-adhesin complex (HRgpA) which hinders direct kinetic comparison of RgpAcat as a monomer with monomeric RgpB. We tested modifications of rgpA identifying a variant that enabled us to isolate histidine-tagged monomeric RgpA (rRgpAH). Kinetic comparisons between rRgpAH and RgpB used benzoyl-L-Arg-4-nitroanilide with and without cysteine and glycylglycine acceptor molecules. With no glycylglycine, values of Km, Vmax, kcat and kcat/Km for each enzyme were similar, but with glycylglycine Km decreased, Vmax increased and kcat increased ~ twofold for RgpB but ~ sixfold for rRgpAH. The kcat/Km for rRgpAH was unchanged whereas that of RgpB more than halved. Recombinant RgpA propeptide inhibited rRgpAH and RgpB with Ki 13 nM and 15 nM Ki respectively slightly more effectively than RgpB propeptide which inhibited rRgpAH and RgpB with Ki 22 nM and 29 nM respectively (p < 0.0001); a result that may be attributable to the divergent propeptide sequences. Overall, the data for rRgpAH reflected observations previously made by others using HRgpA, indicating rRgpAH fidelity and confirming the first production and isolation of functional affinity tagged RgpA.

Importance: The second year of the COVID-19 pandemic saw periods of dire health care resource limitations in the US, sometimes prompting official declarations of crisis, but little is known about how these conditions were experienced by frontline clinicians. Objective: To describe the experiences of US clinicians practicing under conditions of extreme resource limitation during the second year of the pandemic. Design, Setting, and Participants: This qualitative inductive thematic analysis was based on interviews with physicians and nurses providing direct patient care at US health care institutions during the COVID-19 pandemic. Interviews were conducted between December 28, 2020, and December 9, 2021. Exposure: Crisis conditions as reflected by official state declarations and/or media reports. Main Outcomes and Measures: Clinicians' experiences as obtained through interviews. Results: Interviews with 23 clinicians (21 physicians and 2 nurses) who were practicing in California, Idaho, Minnesota, or Texas were included. Of the 23 total participants, 21 responded to a background survey to assess participant demographics; among these individuals, the mean (SD) age was 49 (7.3) years, 12 (57.1%) were men, and 18 (85.7%) self-identified as White. Three themes emerged in qualitative analysis. The first theme describes isolation. Clinicians had a limited view on what was happening outside their immediate practice setting and perceived a disconnect between official messaging about crisis conditions and their own experience. In the absence of overarching system-level support, responsibility for making challenging decisions about how to adapt practices and allocate resources often fell to frontline clinicians. The second theme describes in-the-moment decision-making. Formal crisis declarations did little to guide how resources were allocated in clinical practice. Clinicians adapted practice by drawing on their clinical judgment but described feeling ill equipped to handle some of the operationally and ethically complex situations that fell to them. The third theme describes waning motivation. As the pandemic persisted, the strong sense of mission, duty, and purpose that had fueled extraordinary efforts earlier in the pandemic was eroded by unsatisfying clinical roles, misalignment between clinicians' own values and institutional goals, more distant relationships with patients, and moral distress. Conclusions and Relevance: The findings of this qualitative study suggest that institutional plans to protect frontline clinicians from the responsibility for allocating scarce resources may be unworkable, especially in a state of chronic crisis. Efforts are needed to directly integrate frontline clinicians into institutional emergency responses and support them in ways that reflect the complex and dynamic realities of health care resource limitation.

Decisions around initiating and forgoing treatments for kidney failure are complex, and contemporary approaches to medical decision making are designed to uphold patients' own preferences and values when there are multiple clinically reasonable treatment options. When patients do not have cognitive capacity to make their own decisions, these models can be adapted to support the previously expressed preferences of older adults and to promote open futures as autonomous persons for young children. Nonetheless, an autonomy-focused approach to decision making may not align with other overlapping values and needs of these groups. Dialysis profoundly shapes life experience. Values framing decisions about this treatment extend beyond independence and self-determination and vary between life stages. Patients at the extremes of age may place a strong emphasis on dignity, caring, nurturing, and joy. Models of decision making tailored to support an autonomous individual may also discount the role of family as not only surrogate decision makers but stakeholders whose lives and experience are interwoven with a patient's and will be shaped by their treatment decisions. These considerations underline a need to more flexibly incorporate a diversity of ethical frameworks to support medical decisions, especially for the very young and old, when facing complex medical decisions such as initiating or forgoing treatments for kidney failure.

Importance: Patients receiving maintenance dialysis experience intensive patterns of end-of-life care that might not be consistent with their values. Objective: To evaluate the association of patients' health care values with engagement in advance care planning and end-of-life care. Design, Setting, and Participants: Survey study of patients who received maintenance dialysis between 2015 and 2018 at dialysis centers in the greater metropolitan areas of Seattle, Washington, and Nashville, Tennessee, with longitudinal follow-up of decedents. Logistic regression models were used to estimate probabilities. Data analysis was conducted between May and October 2022. Exposures: A survey question about the value that the participant would place on longevity-focused vs comfort-focused care if they were to become seriously ill. Main Outcomes and Measures: Self-reported engagement in advance care planning and care received near the end of life through 2020 using linked kidney registry data and Medicare claims. Results: Of 933 patients (mean [SD] age, 62.6 [14.0] years; 525 male patients [56.3%]; 254 [27.2%] identified as Black) who responded to the question about values and could be linked to registry data (65.2% response rate [933 of 1431 eligible patients]), 452 (48.4%) indicated that they would value comfort-focused care, 179 (19.2%) that they would value longevity-focused care, and 302 (32.4%) that they were unsure about the intensity of care they would value. Many had not completed an advance directive (estimated probability, 47.5% [95% CI, 42.9%-52.1%] of those who would value comfort-focused care vs 28.1% [95% CI, 24.0%-32.3%] of those who would value longevity-focused care or were unsure; P < .001), had not discussed hospice (estimated probability, 28.6% [95% CI, 24.6%-32.9%] comfort focused vs 18.2% [95% CI, 14.7%-21.7%] longevity focused or unsure; P < .001), or had not discussed stopping dialysis (estimated probability, 33.3% [95% CI, 29.0%-37.7%] comfort focused vs 21.9% [95% CI, 18.2%-25.8%] longevity focused or unsure; P < .001). Most respondents wanted to receive cardiopulmonary resuscitation (estimated probability, 78.0% [95% CI, 74.2%-81.7%] comfort focused vs 93.9% [95% CI, 91.4%-96.1%] longevity focused or unsure; P < .001) and mechanical ventilation (estimated probability, 52.0% [95% CI, 47.4%-56.6%] comfort focused vs 77.9% [95% CI, 74.0%-81.7%] longevity focused or unsure; P < .001). Among decedents, the percentages of participants who received an intensive procedure during the final month of life (estimated probability, 23.5% [95% CI, 16.5%-31.0%] comfort focused vs 26.1% [95% CI, 18.0%-34.5%] longevity focused or unsure; P = .64), discontinued dialysis (estimated probability, 38.3% [95% CI, 32.0%-44.8%] comfort focused vs 30.2% [95% CI, 23.0%-37.8%] longevity focused or unsure; P = .09), and enrolled in hospice (estimated probability, 32.2% [95% CI, 25.7%-38.7%] comfort focused vs 23.3% [95% CI, 16.4%-30.5%] longevity focused or unsure; P = .07) were not statistically different. Conclusions and Relevance: This survey study found that there appeared to be a disconnect between patients' expressed values, which were largely comfort focused, and their engagement in advance care planning and end-of-life care, which reflected a focus on longevity. These findings suggest important opportunities to improve the quality of care for patients receiving dialysis.

Adaptation strategies to ameliorate the impacts of climate change are increasing in scale and scope around the world, with interventions becoming a part of daily life for many people. Though the implications of climate impacts for health and wellbeing are well documented, to date, adaptations are largely evaluated by financial cost and their effectiveness in reducing risk. Looking across different forms of adaptation to floods, we use existing literature to develop a typology of key domains of impact arising from interventions that are likely to shape health and wellbeing. We suggest that this typology can be used to assess the health consequences of adaptation interventions more generally and argue that such forms of evaluation will better support the development of sustainable adaptation planning.

LAY ABSTRACT: Autistic people are more likely to have a gender identity which does not match their sex assigned at birth. Some people experience distress about their sex and gender not matching, which is called gender dysphoria. Such individuals may wish to attend a gender clinic to access healthcare support for gender dysphoria. Currently, there is limited evidence to help clinicians best support autistic people who need healthcare for gender dysphoria. We wanted to find out what healthcare clinicians think about working with autistic patients with gender dysphoria. We interviewed 16 clinicians who work in healthcare services with adults and young people who are autistic and experience gender dysphoria. We recorded the interviews and carefully analysed the content to find key themes. We found that clinicians worked with patients to try and better understand their experiences of gender dysphoria. Clinicians identified features of autism that they believed were related to gender identity and dysphoria including different thinking styles, social differences, and sensory sensitivities. Clinicians noticed that autistic people spoke about their gender in different ways to non-autistic people. Clinicians tried to adapt their practice to better meet the needs of their autistic patients. These adaptations tended to focus on differences in the assessment process, for example, offering longer or shorter appointments and changing their communication style. We conclude that clinicians were offering an individualised approach to autistic patients experiencing gender dysphoria. However, these clinicians were particularly interested in working with autistic people, and so may not be representative of the wider clinician population. Clinicians working in this area should receive training on autism adaptations and the intersection of autism and gender dysphoria.

Gender dysphoria is distress in relation to incongruence between an individual's gender and sex assigned at birth. Gender clinics offer support for gender dysphoria, and there is a higher prevalence of autism in young people attending such clinics than in the general population. We aimed to investigate the lived experiences of autistic young people who have experienced gender dysphoria, and their parents, using a multi-perspectival IPA design. Young autistic people aged 13-17 years (n = 15), and their parents (n = 16), completed in-depth interviews about the young person's experience of gender dysphoria. We analysed each individual transcript to generate individual themes, and for each of the dyads, developed themes which acknowledged the similarities and differences in parent-child perspectives. The first superordinate theme was coping with distress which had two subordinate themes; understanding difficult feelings and focus on alleviating distress with external support. This theme described how young people were overwhelmed by negative feelings which they came to understand as being about gender incongruence and looked to alleviate these feelings through a gender transition. The second superordinate theme was working out who I am which had two subordinate themes: the centrality of different identities and needs and thinking about gender. This theme described how young people and their parents focused on different needs; while young people more often focused on their gender-related needs, parents focused on autism-related needs. We conclude that young people and parents may have different perspectives and priorities when it comes to meeting the needs of autistic young people who experience gender dysphoria.

BACKGROUND: Autistic people are overrepresented in gender clinic settings, but limited evidence is available to guide clinical decision making for this patient group. We aimed to generate a comprehensive understanding of the phenomenology of gender dysphoria in autistic people. METHODS: We conducted a multi-perspectival interpretative phenomenological analysis (IPA), from five different perspectives; autistic young people and adults with experience of gender dysphoria, parents of young people, and clinicians working with autistic people with gender dysphoria in both adult and young person settings (n = 68). RESULTS: IPA analysis resulted in two themes, 'discovering gender identity' and 'the complexities of moving towards gender comfort'. Participants agreed that there was often an interaction between gender dysphoria and features of autism such as sensory sensitivities. There was relative consensus across groups about the need for autism adaptations to be made in gender clinics. Autistic adults were more likely to see autism as an important identity than young people, but both groups were clear that autism did not impair their understanding of gender. In contrast, some parents and clinicians working with young people expressed concern that autism did impact self-understanding. DISCUSSION: While the groups tended to agree on the ways in which particular features of autism can compound gender dysphoria, there were a range of perspectives on the ways in which autism impacted on self-knowledge. CONCLUSION: Recommendations for adaptations when working with autistic people with gender dysphoria are presented.

Importance: There is increasing recognition of the long-term health effects of SARS-CoV-2 infection (sometimes called long COVID). However, little is yet known about the clinical diagnosis and management of long COVID within health systems. Objective: To describe dominant themes pertaining to the clinical diagnosis and management of long COVID in the electronic health records (EHRs) of patients with a diagnostic code for this condition (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10] code U09.9). Design, Setting, and Participants: This qualitative analysis used data from EHRs of a national random sample of 200 patients receiving care in the Department of Veterans Affairs (VA) with documentation of a positive result on a polymerase chain reaction (PCR) test for SARS-CoV-2 between February 27, 2020, and December 31, 2021, and an ICD-10 diagnostic code for long COVID between October 1, 2021, when the code was implemented, and March 1, 2022. Data were analyzed from February 5 to May 31, 2022. Main Outcomes and Measures: A text word search and qualitative analysis of patients' VA-wide EHRs was performed to identify dominant themes pertaining to the clinical diagnosis and management of long COVID. Results: In this qualitative analysis of documentation in the VA-wide EHR, the mean (SD) age of the 200 sampled patients at the time of their first positive PCR test result for SARS-CoV-2 in VA records was 60 (14.5) years. The sample included 173 (86.5%) men; 45 individuals (22.5%) were identified as Black and 136 individuals (68.0%) were identified as White. In qualitative analysis of documentation pertaining to long COVID in patients' EHRs 2 dominant themes were identified: (1) clinical uncertainty, in that it was often unclear whether particular symptoms could be attributed to long COVID, given the medical complexity and functional limitations of many patients and absence of specific markers for this condition, which could lead to ongoing monitoring, diagnostic testing, and specialist referral; and (2) care fragmentation, describing how post-COVID-19 care processes were often siloed from and poorly coordinated with other aspects of care and could be burdensome to patients. Conclusions and Relevance: This qualitative study of documentation in the VA EHR highlights the complexity of diagnosing long COVID in clinical settings and the challenges of caring for patients who have or are suspected of having this condition.
