The interplay of psychosis and non-compliance with fatal outcome in an adult with MSUD

Significant progress has been achieved in enhancing early outcomes for individuals with maple syrup urine disease (MSUD), a rare metabolic disorder that leads to the accumulation of branched-chain amino acids leucine, isoleucine, and valine, where leucine is known as the primary neurotoxic metabolite. Newborn screening is helpful in early diagnosis and implementation of dietary treatment, thus reducing neurological deterioration and complications in young children. However, patients face the life-long challenge of maintaining metabolic control through adherence to a strict low-leucine diet to avoid long-term consequences of chronic hyperleucinemia, which include cognitive deficits, mood disorders, and movement disorders. This case report exemplifies the complex involvement of MSUD in adult survivors. Despite presenting early in life, the patient thrived until the onset of psychiatric symptoms. The subject of this case is a 25-year-old woman with MSUD, who remained in her usual state of health until presentation to the emergency department (ED) with psychosis and altered mental status. However, due to a lack of medical records and poor communication, there was a delay in considering MSUD as a primary cause of her psychiatric symptoms. Although a genetics consultation was later arranged and efforts were made to decrease plasma leucine to the therapeutic range, these interventions proved inadequate in halting her deterioration in health. Her condition worsened within 72 h, culminating in her untimely death. This case emphasizes the comorbidity of psychiatric involvement in MSUD, which contributes to metabolic decompensation that can lead to cerebral edema and death. This case also highlights the pressing need for enhanced strategies for the acute management and long-term care of MSUD patients with psychiatric involvement, particularly in scenarios where mental disturbance could lead to noncompliance.

Followership: an undervalued concept in effective teams within the military and NHS

INTRODUCTION

Leadership is accepted as a crucial component of effective working within teams. Followership's contribution to successful performance is increasingly recognised but understudied. This study evaluated followership levels in military doctors at different stages of their careers and made recommendations for how followership concepts can be used to develop the self and better understand the challenges of small team working.

METHODS

A self-report study in which Kelley's followership questionnaire was distributed to 64 military doctors in three cohorts. 53 results were assessed using Kelley's followership framework. Subgroup analysis was undertaken to look at differences depending on service, age, gender and career stage.

RESULTS

The study demonstrated a predominant exemplary followership style within military doctors. No statistical difference was identified at the 0.05 level in followership by career stage, age, gender or service in the sample group.

CONCLUSION

This study gives insight into the attributes of doctors within the Defence Medical Services and laid out a methodology for further cohort evaluations of followership. It made recommendations on the areas of the field that require further research and how followership concepts may be included in further development courses and reporting for military medical personnel.

Emotional intelligence in military medical officers in the Defence Medical Services

BACKGROUND

Emotional intelligence (EI) is a concept describing an individual's ability to understand, process and act accordingly on others' and one's own emotions. It is a desirable quality for people working in teams and is beneficial to the individual in many ways. It is increasingly recognised that understanding and developing EI are important to working in the healthcare environment. It becomes especially pertinent in the deployed Defence Medical Services (DMS), where clinicians often fulfil a significant leadership role in a small team.

METHODS

This study was performed with the aim of exploring the role of EI in military doctors in the UK DMS. EI was measured in a cohort of 64 military doctors by way of a validated self-assessment questionnaire. Results were tested for differences in EI between different services and career stages.

RESULTS

The survey had an 83% return rate. There was roughly equal distribution between service, career groups and ages across the study population. There were more men than women. The population showed consistently high EI scores compared with control data. There were no statistical differences in EI scores between services or genders. Foundation doctors showed the highest EI scores and consultants the lowest (6.05 vs 5.3).

CONCLUSION

It was demonstrated that military doctors have consistently high EI score, especially at the most junior level. This suggests that traits deemed desirable by the single service selection processes also pertain to high EI without it being specifically measured for. The dangers of having too high EI and the benefits of having a range of EI within a team were discussed. There were limitations of being unable to obtain qualitative data and not including primary healthcare staff. Several recommendations were set out as to how the DMS may use or further investigate EI with regard to training and recruitment.

Hyperon Polarization along the Beam Direction Relative to the Second and Third Harmonic Event Planes in Isobar Collisions at sqrt[s_{NN}]=200 GeV

The polarization of Λ and Λ[over ¯] hyperons along the beam direction has been measured relative to the second and third harmonic event planes in isobar Ru+Ru and Zr+Zr collisions at sqrt[s_{NN}]=200  GeV. This is the first experimental evidence of the hyperon polarization by the triangular flow originating from the initial density fluctuations. The amplitudes of the sine modulation for the second and third harmonic results are comparable in magnitude, increase from central to peripheral collisions, and show a mild p_{T} dependence. The azimuthal angle dependence of the polarization follows the vorticity pattern expected due to elliptic and triangular anisotropic flow, and qualitatively disagrees with most hydrodynamic model calculations based on thermal vorticity and shear induced contributions. The model results based on one of existing implementations of the shear contribution lead to a correct azimuthal angle dependence, but predict centrality and p_{T} dependence that still disagree with experimental measurements. Thus, our results provide stringent constraints on the thermal vorticity and shear-induced contributions to hyperon polarization. Comparison to previous measurements at RHIC and the LHC for the second-order harmonic results shows little dependence on the collision system size and collision energy.

A Policy Mapping Analysis of the U.S. Congressional Approach to Medical Aid-in-Dying

This study examines the goals of medical aid-in-dying (MAID) legislation introduced to the US Congress from 1994-2020 using a policy mapping analysis approach. Using congress.gov, we identified 98 bills, 23 bills were analyzed in this study. Most of the bills aimed to restrict the use of federal funds, to regulate the drugs commonly used for MAID, to prohibit the development of policies or practices supporting MAID, and to regulate practitioners' roles in MAID. In practice, these bills would limit patient access to MAID by restricting drugs, funds, health care services, legal assistance, policy, and research. These findings suggest there lacks congressional support for MAID, even though polls of the public are divided yet favorable. Policymakers who support MAID should consider affirmative policies that 1) prevent MAID policies from discriminating against vulnerable groups, 2) support funding to study the use of MAID, and 3) build avenues to allow all qualified people to access MAID in places where it is legal.

Global rural health disparities in Alzheimer's disease and related dementias: State of the science

INTRODUCTION

Individuals living in rural communities are at heightened risk for Alzheimer's disease and related dementias (ADRD), which parallels other persistent place-based health disparities. Identifying multiple potentially modifiable risk factors specific to rural areas that contribute to ADRD is an essential first step in understanding the complex interplay between various barriers and facilitators.

METHODS

An interdisciplinary, international group of ADRD researchers convened to address the overarching question of: "What can be done to begin minimizing the rural health disparities that contribute uniquely to ADRD?" In this state of the science appraisal, we explore what is known about the biological, behavioral, sociocultural, and environmental influences on ADRD disparities in rural settings.

RESULTS

A range of individual, interpersonal, and community factors were identified, including strengths of rural residents in facilitating healthy aging lifestyle interventions.

DISCUSSION

A location dynamics model and ADRD-focused future directions are offered for guiding rural practitioners, researchers, and policymakers in mitigating rural disparities.

HIGHLIGHTS

Rural residents face heightened Alzheimer's disease and related dementia (ADRD) risks and burdens due to health disparities. Defining the unique rural barriers and facilitators to cognitive health yields insight. The strengths and resilience of rural residents can mitigate ADRD-related challenges. A novel "location dynamics" model guides assessment of rural-specific ADRD issues.

Medical Aid in Dying: How Might U.S. Policy Prevent Suffering at the End of Life?

Medical aid in dying refers to policies that allow terminally ill patients to seek assistance from their medical providers to obtain medications to hasten death. In this paper, we used a 7-point policy analysis model to examine the diversity of medical aid in dying policies that exist in jurisdictions (states and territories) in the U.S. and the implications of these policies for suffering at end of life. As of this writing, these practices are available in 12 jurisdictions, including 11 states and the District of Columbia. Legalization has occurred via statutory approaches in 10 jurisdictions and permissive approaches in two jurisdictions. We discuss the structures of these laws, the requirements for participation, and the limitations created by having jurisdiction-specific policies on such broad, bioethical issues. Existing laws appear to relieve suffering in patients at end of life. Jurisdictional differences create barriers to comprehensive expansion but provide insights into practice in different contexts.

Measurements of the Elliptic and Triangular Azimuthal Anisotropies in Central ^{3}He+Au, d+Au and p+Au Collisions at sqrt[s_{NN}]=200 GeV

The elliptic (v_{2}) and triangular (v_{3}) azimuthal anisotropy coefficients in central ^{3}He+Au, d+Au, and p+Au collisions at sqrt[s_{NN}]=200  GeV are measured as a function of transverse momentum (p_{T}) at midrapidity (|η|<0.9), via the azimuthal angular correlation between two particles both at |η|<0.9. While the v_{2}(p_{T}) values depend on the colliding systems, the v_{3}(p_{T}) values are system independent within the uncertainties, suggesting an influence on eccentricity from subnucleonic fluctuations in these small-sized systems. These results also provide stringent constraints for the hydrodynamic modeling of these systems.

Observation of Directed Flow of Hypernuclei _{Λ}^{3}H and _{Λ}^{4}H in sqrt[s_{NN}]=3 GeV Au+Au Collisions at RHIC

We report here the first observation of directed flow (v_{1}) of the hypernuclei _{Λ}^{3}H and _{Λ}^{4}H in mid-central Au+Au collisions at sqrt[s_{NN}]=3  GeV at RHIC. These data are taken as part of the beam energy scan program carried out by the STAR experiment. From 165×10^{6} events in 5%-40% centrality, about 8400 _{Λ}^{3}H and 5200 _{Λ}^{4}H candidates are reconstructed through two- and three-body decay channels. We observe that these hypernuclei exhibit significant directed flow. Comparing to that of light nuclei, it is found that the midrapidity v_{1} slopes of _{Λ}^{3}H and _{Λ}^{4}H follow baryon number scaling, implying that the coalescence is the dominant mechanism for these hypernuclei production in the 3 GeV Au+Au collisions.

Beam Energy Dependence of Triton Production and Yield Ratio (N_{t}×N_{p}/N_{d}^{2}) in Au+Au Collisions at RHIC

We report the triton (t) production in midrapidity (|y|<0.5) Au+Au collisions at sqrt[s_{NN}]=7.7-200  GeV measured by the STAR experiment from the first phase of the beam energy scan at the Relativistic Heavy Ion Collider. The nuclear compound yield ratio (N_{t}×N_{p}/N_{d}^{2}), which is predicted to be sensitive to the fluctuation of local neutron density, is observed to decrease monotonically with increasing charged-particle multiplicity (dN_{ch}/dη) and follows a scaling behavior. The dN_{ch}/dη dependence of the yield ratio is compared to calculations from coalescence and thermal models. Enhancements in the yield ratios relative to the coalescence baseline are observed in the 0%-10% most central collisions at 19.6 and 27 GeV, with a significance of 2.3σ and 3.4σ, respectively, giving a combined significance of 4.1σ. The enhancements are not observed in peripheral collisions or model calculations without critical fluctuation, and decreases with a smaller p_{T} acceptance. The physics implications of these results on the QCD phase structure and the production mechanism of light nuclei in heavy-ion collisions are discussed.

Measurement of Sequential ϒ Suppression in Au+Au Collisions at sqrt[s_{NN}]=200 GeV with the STAR Experiment

We report on measurements of sequential ϒ suppression in Au+Au collisions at sqrt[s_{NN}]=200  GeV with the STAR detector at the Relativistic Heavy Ion Collider (RHIC) through both the dielectron and dimuon decay channels. In the 0%-60% centrality class, the nuclear modification factors (R_{AA}), which quantify the level of yield suppression in heavy-ion collisions compared to p+p collisions, for ϒ(1S) and ϒ(2S) are 0.40±0.03(stat)±0.03(sys)±0.09(norm) and 0.26±0.08(stat)±0.02(sys)±0.06(norm), respectively, while the upper limit of the ϒ(3S) R_{AA} is 0.17 at a 95% confidence level. This provides experimental evidence that the ϒ(3S) is significantly more suppressed than the ϒ(1S) at RHIC. The level of suppression for ϒ(1S) is comparable to that observed at the much higher collision energy at the Large Hadron Collider. These results point to the creation of a medium at RHIC whose temperature is sufficiently high to strongly suppress excited ϒ states.

Beam Energy Dependence of Fifth- and Sixth-Order Net-Proton Number Fluctuations in Au+Au Collisions at RHIC

We report the beam energy and collision centrality dependence of fifth and sixth order cumulants (C_{5}, C_{6}) and factorial cumulants (κ_{5}, κ_{6}) of net-proton and proton number distributions, from center-of-mass energy (sqrt[s_{NN}]) 3 GeV to 200 GeV Au+Au collisions at RHIC. Cumulant ratios of net-proton (taken as proxy for net-baryon) distributions generally follow the hierarchy expected from QCD thermodynamics, except for the case of collisions at 3 GeV. The measured values of C_{6}/C_{2} for 0%-40% centrality collisions show progressively negative trend with decreasing energy, while it is positive for the lowest energy studied. These observed negative signs are consistent with QCD calculations (for baryon chemical potential, μ_{B}≤110  MeV) which contains the crossover transition range. In addition, for energies above 7.7 GeV, the measured proton κ_{n}, within uncertainties, does not support the two-component (Poisson+binomial) shape of proton number distributions that would be expected from a first-order phase transition. Taken in combination, the hyperorder proton number fluctuations suggest that the structure of QCD matter at high baryon density, μ_{B}∼750  MeV at sqrt[s_{NN}]=3  GeV is starkly different from those at vanishing μ_{B}∼24  MeV at sqrt[s_{NN}]=200  GeV and higher collision energies.

Contextuality and context-sensitivity in probabilistic models of cognition

The context-sensitivity of cognition has been demonstrated across a wide range of cognitive functions such as perception, memory, judgement and decision making. A related term, 'contextuality', has appeared from the field of quantum cognition, with mounting empirical evidence demonstrating that cognitive phenomena are sometimes contextual. Contextuality is a subtle notion that influences how we must view the properties of the cognitive phenomenon being studied. This article addresses the questions: What does it mean for a cognitive phenomenon to be contextual? What are the implications of contextuality for probabilistic models of cognition? How does contextuality differ from context-sensitivity? Starting from George Boole's "conditions of possible experience", we argue that a probabilistic model of a cognitive phenomenon is necessarily subject to an assumption of realism. By this we mean that the phenomenon being studied is assumed to have cognitive properties with a definite value independent of observation. In contrast, quantum cognition holds that a cognitive property maybe indeterminate, i.e., its properties do not have well established values prior to observation. We argue that indeterminacy is sufficient for incompatibility between cognitive properties. In turn, incompatibility is necessary for their contextuality. The significance of this argument for cognitive psychology is the following:if a cognitive phenomenon is found to be contextual, then there is reason to believe it may be indeterminate. We illustrate by means of two crowdsourced experiments how context-sensitivity and contextuality of cognitive properties in the form of facial trait judgements can be characterized from empirical data. Finally, we conceptually and formally contrast contextuality with context-sensitivity. We propose that both involve a form of context dependence, with causality being the differentiating factor: the context dependence in context-sensitivity has a causal basis, whereas the context dependence in contextuality is acausal. The resulting implications for probabilistic models of cognition are discussed.

Conversations about Community, Connection to Place, and Housing Preferences among Aging Adults in Lexington, Kentucky

While many researchers have called for housing to be addressed in age-friendly cities and communities, little research exists to guide communities through this process. To maximize the potential for adults to age in place, researchers partnered with a local Age-Friendly community initiative to conduct focus groups and learn more about residents' preferences related to housing and residential space. The focus group data offered a glimpse into aging residents' perspectives on housing to inform planning and development of housing in a mid-size city. This second phase of a sequential mixed methods study included qualitative focus groups with 19 aging individuals. Focus group sessions sought to better understand previously identified housing preferences, aging adults' sense of community, and their connection to place. Findings suggest that aging participants cared not only about the physical structure of their home, but also the community-based aspects of where they live. Study implications suggest that social workers, working with and alongside community members and aging-service providers who have local knowledge, can support age-friendly housing models that consider the housing preferences of older residents, as well as the resources and limitations of their community.

Identifying Aging Adults' Housing Preferences: An Age-Friendly Initiative

Community planning around housing needs of older adults is, at present, very understudied. This study stemmed from a practical need to determine the housing preferences of residents as part of an Age Friendly Community initiative. Data presented in this paper focus on the quantitative component of a sequential mixed methods study examining attitudes and preferences about housing. This first phase of this project involved data collected from 1,514 residents aged 30+ using a researcher-devised survey of 43 items. There was little difference in housing preferences between older and younger respondents or among those with varying financial means. Analysis revealed the most important housing considerations were safety in home, affordability, privacy, proximity to services frequently used, and accessibility. An unexpected finding was that almost half of older respondents expressed a willingness to share a home with a roommate. There were also differences in preferences on home environment based on current marital status. Data suggests that city planners and property developers should prioritize these preferences when planning for the housing-related needs of older residents. Future research should examine the interpretation of housing preferences, such as qualitative exploration of what it means for housing to be "safe" or 'affordable.'

MEDICAL AID IN DYING: DOES POLICY PREVENT SUFFERING AT THE END OF LIFE?

Medical aid in dying (MAID) reflects the legal provision for qualifying, terminally ill individuals to receive a prescription from their medical provider for self-ingestion to hasten death. This policy analysis examines current MAID policy with a focus on MAID’s intended relief of suffering. Using Wallace’s (2015) policy model, we evaluated MAID on: policy description, historical context, development of the policy, efficiency, alternative programs, effectiveness, and unintended consequences. Policy description: Currently legal in 10 jurisdictions (nine states and Washington, DC), common goals include relieving suffering and promoting self-determination. Historical context: Following a failed attempt at federal legalization, the U.S. adopted an incremental, jurisdiction-based approach to legalization beginning in Oregon (1994). Development of the policy: Although all statutes imitate Oregon’s model, subtle differences exist. Efficiency: Although each policy includes waiting periods that vary in sequential order and duration, revisions have targeted waiting periods to improve efficiency. Alternative programs: Frequently considered an alternative to MAID, existing statutes encourage providers to discuss palliative options. Effectiveness: Despite appearing effective in promoting self-determination, MAID-related complications (e.g., vomiting) may exacerbate suffering. Unintended consequences: MAID’s requirement of clinician participation may place providers in situations that challenge their self-determination and provoke distress. In sum, many questions remain unanswered regarding MAID’s effectiveness and efficiency. Thus, more data are needed. Ethical implications will continue to be debated, though policy implications (e.g., who uses MAID, the number of unique providers, the emergence of complications, those present during death) greatly impact implementation and overall choices to limit suffering at the end of life.

RESULTS FROM A PLATFORM-BASED CLINICAL TRIAL FOR PERSONS DIAGNOSED WITH MILD COGNITIVE IMPAIRMENT

The process of receiving a diagnosis of mild cognitive impairment (MCI) is overwhelming. Individuals may experience adaptive or maladaptive responses to the diagnosis. Five specific areas of maladaptive response were previously identified, including 1) failure to plan for future decline, 2) decreased compliance and interaction with medical care providers, 3) decreased confidence and reduced social engagement, 4) increased physical limitations and mobility, and 5) decreased medication compliance. This pilot study reports on the delivery of the platform-based trial for persons diagnosed with MCI with survey data and qualitative focus groups data (n=38). The study consisted of a single-site platform trial examining the intervention group. Using this approach allowed the participants to explore different biopsychosocial arms of the intervention. Second, the platform design allowed researchers to determine the effects of the interventions on patient help-seeking and adherence behavior in real-world care. Feasibility, opportunities, and challenges will be discussed. Opportunities include the group’s cohesion with the group-based intervention, which increased engagement for study group participation. Additionally, participants were most susceptive to intervention components that were novel (i.e., mindfulness) and administered by a professional (i.e., pharmacist, physical therapist) as opposed to self-facilitated activities. Challenges include frequency of study visits, the study partner requirement, and the in-person delivery of the intervention. These challenges were further compounded by the COVID-19 pandemic. Findings from this study offer considerations in implementing support programming and clinical research for persons diagnosed with MCI. The presentation will also include discussion on COVID-19 pandemic-related protocol modifications of this intervention study.

STARTING THE CONVERSATION: FINDINGS FROM AN ADVANCE CARE DIRECTIVE WORKSHOP

Every adult that enters a hospital is asked about an advance care directive (ACD) document. The completion rates of care directives started to grow in 2016, when Medicare provided a reimbursement benefit in the annual wellness exam. Previous data shows only 37% of older Americans have an ACD, of that 64% are white. Previous studies report data from medical visits, however, advance directive discussions conducted in a community setting has not yet been explored. This pilot study examines readiness to have discussions with your appointed decision-maker, primary care provider, and complete ACD document. This was a community workshop with a physician-led presentation regarding medical choices, followed by break-out groups with trained moderators reviewing ACD materials. Data from pre/posttest along with qualitative comments addressing information seeking (pre) and additional comments (post) are included. The workshop increased participants readiness to identify an individual to make medical decisions and put into writing the type of medical care they desire. It also showed resistance to having conversations with a person's primary care provider and chosen health care agent. Challenges included the pre/posttest completion rate and the inability to compare a control group. Viewing advance directive completion within the self-determination theory assists in understanding the need for a novel setting to promote relatedness. Further research needs to be done on community setting ACD workshops to provide a space for participants to be better informed in the ACD process. Community workshops need to be examined to have a broader spectrum of inclusion within historically marginalized communities.

STIFLED UTILIZATION OF DEMENTIA-RELATED HEALTHCARE SERVICES DUE TO STIGMA IN RURAL APPALACHIA

Residency in rural Appalachia is linked with heightened morbidity and mortality due to a myriad of conditions, many of which are associated with increased risk and prevalence of Alzheimer’s disease and related dementias (ADRD). Despite this, access to and utilization of dementia-specific healthcare services in the region are limited. This study presents community-based stigma associated with enrollment in healthcare clinical research offered in rural Appalachia. Additional data from focus groups with care partners of people with memory impairment in rural Appalachia discuss implications of stigma in their communities. Findings elaborate on recruitment challenges associated with terminology, such as caregiver and dementia, as well as availability of diagnosticians. This study illustrates unique characteristics needed for community-based education programs tailored to the culture and customs of rural regions in order to increase utilization of healthcare for older adults at risk or living with ADRD.

USE OF TECHNOLOGY TO DELIVER AND MONITOR NONPHARMACOLOGICAL INTERVENTION FOR ADRD WITH BEHAVIORAL SYMPTOMS

Onset of the COVID-19 pandemic created numerous barriers to providing care supports and clinical research for persons living with Alzheimer’s disease and related dementias (ADRD). Technology offered one avenue for continued care support and clinical data collection. This study reports on the use of technology to deliver a 6-week, non-pharmacological care intervention directed toward caregivers of persons with ADRD and remote data collection including cognitive assessment, biometric data, and survey data for community-residing persons with ADRD and behavioral symptoms (N=28). Benefits and challenges of such technology use for intervention delivery and data collection will be discussed. Benefits include increased geographical outreach, no travel time, and greater scheduling flexibility. Challenges include access to technology (equipment and/or internet), internet connection quality, ease of use, and equipment return at study completion. These findings offer specific aspects to consider while designing and implementing remote care programming and clinical research for community-residing persons with ADRD.

INCREASING DEMENTIA CARE MASTERY FOR RURAL CAREGIVERS: LESSONS FROM ADAPTING THE HARMONY @ HOME INTERVENTION

Providing care support to rural Alzheimer’s disease and related dementia (ADRD) caregivers has always been challenging, but particularly with the COVID-19 pandemic, new barriers have emerged for families in accessing care support. Delivered via telehealth, Harmony at HOME (H@H) provides dementia care mastery for caregivers of persons with ADRD in the skills of assessing and modifying the home environment to promote "person-environment fit," whereby increasing functional activity engagement and minimizing maladaptive behaviors. To enhance care supports specific to the needs of rural communities, this study reports the findings of two focus groups with rural caregivers who participated in the H@H intervention. Focus groups were aimed to identify the needs of caregivers in rural communities to guide adaptation approaches for future implementation of the H@H intervention in these underserved areas. Additional studies to assess real-world efficacy of the adaptations to H@H are needed as a next step toward implementing this intervention in clinical, home care settings.

Collision-System and Beam-Energy Dependence of Anisotropic Flow Fluctuations

Elliptic flow measurements from two-, four-, and six-particle correlations are used to investigate flow fluctuations in collisions of U+U at sqrt[s_{NN}]=193  GeV, Cu+Au at sqrt[s_{NN}]=200  GeV and Au+Au spanning the range sqrt[s_{NN}]=11.5-200  GeV. The measurements show a strong dependence of the flow fluctuations on collision centrality, a modest dependence on system size, and very little if any, dependence on particle species and beam energy. The results, when compared to similar LHC measurements, viscous hydrodynamic calculations, and trento model eccentricities, indicate that initial-state-driven fluctuations predominate the flow fluctuations generated in the collisions studied.

Evidence for Nonlinear Gluon Effects in QCD and Their Mass Number Dependence at STAR

The STAR Collaboration reports measurements of back-to-back azimuthal correlations of di-π^{0}s produced at forward pseudorapidities (2.6<η<4.0) in p+p, p+Al, and p+Au collisions at a center-of-mass energy of 200 GeV. We observe a clear suppression of the correlated yields of back-to-back π^{0} pairs in p+Al and p+Au collisions compared to the p+p data. The observed suppression of back-to-back pairs as a function of transverse momentum suggests nonlinear gluon dynamics arising at high parton densities. The larger suppression found in p+Au relative to p+Al collisions exhibits a dependence of the saturation scale Q_{s}^{2} on the mass number A. A linear scaling of the suppression with A^{1/3} is observed with a slope of -0.09±0.01.

Measurements of Proton High-Order Cumulants in sqrt[s_{NN}]=3 GeV Au+Au Collisions and Implications for the QCD Critical Point

We report cumulants of the proton multiplicity distribution from dedicated fixed-target Au+Au collisions at sqrt[s_{NN}]=3.0  GeV, measured by the STAR experiment in the kinematic acceptance of rapidity (y) and transverse momentum (p_{T}) within -0.5<y<0 and 0.4<p_{T}<2.0  GeV/c. In the most central 0%-5% collisions, a proton cumulant ratio is measured to be C_{4}/C_{2}=-0.85±0.09 (stat)±0.82 (syst), which is 2σ below the Poisson baseline with respect to both the statistical and systematic uncertainties. The hadronic transport UrQMD model reproduces our C_{4}/C_{2} in the measured acceptance. Compared to higher energy results and the transport model calculations, the suppression in C_{4}/C_{2} is consistent with fluctuations driven by baryon number conservation and indicates an energy regime dominated by hadronic interactions. These data imply that the QCD critical region, if created in heavy-ion collisions, could only exist at energies higher than 3 GeV.

Measurements of _{Λ}^{3}H and _{Λ}^{4}H Lifetimes and Yields in Au+Au Collisions in the High Baryon Density Region

We report precision measurements of hypernuclei _{Λ}^{3}H and _{Λ}^{4}H lifetimes obtained from Au+Au collisions at sqrt[s_{NN}]=3.0  GeV and 7.2 GeV collected by the STAR experiment at the Relativistic Heavy Ion Collider, and the first measurement of _{Λ}^{3}H and _{Λ}^{4}H midrapidity yields in Au+Au collisions at sqrt[s_{NN}]=3.0  GeV. _{Λ}^{3}H and _{Λ}^{4}H, being the two simplest bound states composed of hyperons and nucleons, are cornerstones in the field of hypernuclear physics. Their lifetimes are measured to be 221±15(stat)±19(syst)  ps for _{Λ}^{3}H and 218±6(stat)±13(syst)  ps for _{Λ}^{4}H. The p_{T}-integrated yields of _{Λ}^{3}H and _{Λ}^{4}H are presented in different centrality and rapidity intervals. It is observed that the shape of the rapidity distribution of _{Λ}^{4}H is different for 0%-10% and 10%-50% centrality collisions. Thermal model calculations, using the canonical ensemble for strangeness, describes the _{Λ}^{3}H yield well, while underestimating the _{Λ}^{4}H yield. Transport models, combining baryonic mean-field and coalescence (jam) or utilizing dynamical cluster formation via baryonic interactions (phqmd) for light nuclei and hypernuclei production, approximately describe the measured _{Λ}^{3}H and _{Λ}^{4}H yields. Our measurements provide means to precisely assess our understanding of the fundamental baryonic interactions with strange quarks, which can impact our understanding of more complicated systems involving hyperons, such as the interior of neutron stars or exotic hypernuclei.

Probing the Gluonic Structure of the Deuteron with J/ψ Photoproduction in d+Au Ultraperipheral Collisions

Understanding gluon density distributions and how they are modified in nuclei are among the most important goals in nuclear physics. In recent years, diffractive vector meson production measured in ultraperipheral collisions (UPCs) at heavy-ion colliders has provided a new tool for probing the gluon density. In this Letter, we report the first measurement of J/ψ photoproduction off the deuteron in UPCs at the center-of-mass energy sqrt[s_{NN}]=200  GeV in d+Au collisions. The differential cross section as a function of momentum transfer -t is measured. In addition, data with a neutron tagged in the deuteron-going zero-degree calorimeter is investigated for the first time, which is found to be consistent with the expectation of incoherent diffractive scattering at low momentum transfer. Theoretical predictions based on the color glass condensate saturation model and the leading twist approximation nuclear shadowing model are compared with the data quantitatively. A better agreement with the saturation model has been observed. With the current measurement, the results are found to be directly sensitive to the gluon density distribution of the deuteron and the deuteron breakup process, which provides insights into the nuclear gluonic structure.

Search for the Chiral Magnetic Effect via Charge-Dependent Azimuthal Correlations Relative to Spectator and Participant Planes in Au+Au Collisions at sqrt[s_{NN}]=200 GeV

The chiral magnetic effect (CME) refers to charge separation along a strong magnetic field due to imbalanced chirality of quarks in local parity and charge-parity violating domains in quantum chromodynamics. The experimental measurement of the charge separation is made difficult by the presence of a major background from elliptic azimuthal anisotropy. This background and the CME signal have different sensitivities to the spectator and participant planes, and could thus be determined by measurements with respect to these planes. We report such measurements in Au+Au collisions at a nucleon-nucleon center-of-mass energy of 200 GeV at the Relativistic Heavy-Ion Collider. It is found that the charge separation, with the flow background removed, is consistent with zero in peripheral (large impact parameter) collisions. Some indication of finite CME signals is seen in midcentral (intermediate impact parameter) collisions. Significant residual background effects may, however, still be present.

Comparison of behaviors characteristic of autism spectrum disorder behaviors and behavioral and psychiatric symptoms of dementia

BACKGROUND

Similarities exist in behavioral expression of autism spectrum disorder (ASD) and Alzheimer's disease and related dementias (ADRD). The purpose of this study was to assess presence of behavioral and psychiatric symptoms of dementia (BPSD) and ASD-like behaviors in adults with ADRD.

METHODS

Using a cross-sectional design, data from University of Kentucky Alzheimer's Disease Center participant cohort were used. Hierarchical linear regression was used to assess (1) the relationship between ASD-like behaviors (measured by the Gilliam Autism Rating Scale-Second Edition, GARS-2) and BPSD measured by the Neuropsychiatric Inventory (NPI), and (2) the relationship between ASD-like behaviors and dementia severity (measured by the Clinical Dementia Rating [CDR] sum of boxes), when controlling for BPSD.

RESULTS

Complete data were available for 142 participants. Using α of 0.05, analyses identified ASD behaviors were significantly associated with BPSD severity ratings (r = 0.47; p < 0.001) and dementia severity (r = 0.46; p < 0.001). GARS-2 explained 6.1% (p < 0.001) of variance in CDR sum of boxes when controlling for NPI and other covariates.

DISCUSSION

There is significant overlap in behaviors characteristic of ASD and BPSD as assessed by the NPI and GARS-2, despite the use of these instruments in disparate developmental vs. aging settings. ASD behaviors appear to not be solely present in early childhood as a manifestation of ASD but are also present in older adults with neurodegenerative cognitive impairment. Such associations warrant additional research into causation, assessment, and behavioral interventions to further enable new therapeutic approaches targeting ASD behaviors across the lifespan.

Becoming a Caregiver: Experiences of Young Adults Moving into Family Caregiving Roles

While the vast majority of family caregivers struggle to find balance between different roles in their lives, young adult caregivers are faced with the atypical challenge of caring for family member while simultaneously accomplishing developmental tasks typical of this stage in life (e.g., establishing career, developing romantic relationships). This exploratory, qualitative study examined strategies used by young adults to adopt family caregiving roles. These strategies can be described as embracement, compromise, and integration. While each approach allowed for the young adult to facilitate their caregiving role, additional research is needed to understand how the strategy affects the emerging adult's development.

Free-roaming dog population dynamics in Ranchi, India

Rabies causes approximately 20,000 human deaths in India each year. Nearly all of these occur following dog bites. Large-scale, high-coverage dog rabies vaccination campaigns are the cornerstone of rabies elimination strategies in both human and dog populations, although this is particularly challenging to achieve in India as a large proportion of the dog population are free-roaming and unowned. Further, little is known about free-roaming dog ecology in India which makes defining optimum vaccination strategies difficult. In this study, data collected using a mobile phone application during three annual mass vaccination and neutering (surgical sterilisation of both males and females) campaigns of free-roaming dogs in Ranchi, India (during which a total of 43,847 vaccinations, 26,213 neuter surgeries and 28,172 re-sight observations were made) were interrogated, using two novel approaches to estimate the proportion of neutered dogs that were lost from the city (assumed due to mortality or migration) between campaign years. Analysis revealed high losses of neutered dogs each year, ranging from 25.3% (28.2-22.8) to 55.8% (57.0-54.6). We also estimated that the total population declined by 12.58% (9.89-15.03) over the three-year period. This demonstrates that there is a high turnover of free-roaming dogs and that despite neutering a large number of dogs in an annual sterilisation campaign, the decline in population size was modest over a three-year time period. These findings have significant implications for the planning of rabies vaccination campaigns and population management programmes as well as highlighting the need for further research into the demographics of free-roaming, unowned dogs in India.

Measurement of the Sixth-Order Cumulant of Net-Proton Multiplicity Distributions in Au+Au Collisions at sqrt[s_{NN}]=27, 54.4, and 200 GeV at RHIC

According to first-principle lattice QCD calculations, the transition from quark-gluon plasma to hadronic matter is a smooth crossover in the region μ_{B}≤T_{c}. In this range the ratio, C_{6}/C_{2}, of net-baryon distributions are predicted to be negative. In this Letter, we report the first measurement of the midrapidity net-proton C_{6}/C_{2} from 27, 54.4, and 200 GeV Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC). The dependence on collision centrality and kinematic acceptance in (p_{T}, y) are analyzed. While for 27 and 54.4 GeV collisions the C_{6}/C_{2} values are close to zero within uncertainties, it is observed that for 200 GeV collisions, the C_{6}/C_{2} ratio becomes progressively negative from peripheral to central collisions. Transport model calculations without critical dynamics predict mostly positive values except for the most central collisions within uncertainties. These observations seem to favor a smooth crossover in the high-energy nuclear collisions at top RHIC energy.

The Dyad Dilemma: Strategies to Recruit Study Partners for Mild Cognitive Impairment Clinical Trials

Mild cognitive impairment (MCI) research faces challenges to successful enrollment, especially with clinical trial studies. This study explores researchers’ experiences recruiting from a U.S. Alzheimer’s Disease Center for a pilot, platform trial of biopsychosocial interventions for MCI dyads. Individuals with MCI that met the inclusion criteria for the study were invited to participate (n=39). Thematic analysis of recruitment case notes was utilized to track participants’ and study partners’ interest in participation. In most cases, participants with MCI were interested and willing to enroll and study partners were not. Recruiting persons with MCI and their study partners for clinical trials research may require specialized communication messaging such as education about how interventions address the needs of MCI, along with training on the relationship of MCI to cognitive decline. This presentation highlights effective strategies to engage study partners into recruitment for MCI research such as creating more flexible participation roles and offerings.

The Relationship Between Loneliness and the COVID-19 Pandemic on Cognition and Well-Being in Older Adults

Social distancing is necessary to limit the spread of Covid-19. However, many older adults are predisposed to isolation and loneliness despite calls to socially distance. The current study examined loneliness during Covid-19 in relation to cognition and wellbeing in older adults. Data were extracted from a U.S. ADRC longitudinal study of aging database. Cognition was assessed using the NACC UDS 3.0 battery. Measures of well-being include: Short Form Health Survey, Subjective Memory Assessment, and Geriatric Depression Scale. Measurement of loneliness was selected from the NIH ADRC Covid-19 questionnaire. Data were from 115 older adults with normal cognition or MCI with a visit ≤18 months before research stoppage in March 2020 and after resumption in late-June 2020. Cognition and wellbeing are compared before and after onset of pandemic. Isolation due to Covid-19 may have long-term implications. Results of this study will highlight the need for acute assessments and psychosocial interventions.

Cognitive Decline Over a 5-Year Period: The National Health and Aging Trends Study

The classification of Alzheimer’s disease and related dementia (ADRD) is important for understanding the progression of cognitive decline. This longitudinal study used data from the National Health and Aging Trends Study (NHATS). A sample of 3,287 eligible Medicare beneficiaries were included in the study. Nine cognitive profiles were examined from Waves 1 to 5 (2011-2015). Discriminant factor analysis was used to identify factors that differentiated across the cognitive profiles. Results showed that 1,076 had some measure of “possible” or “probable” dementia over the 5 years. In Wave 1, there were 104 self-reported ADRD diagnoses, and in Wave 5, there were 327 self-reported ADRD diagnoses. Social participation was an important factor in those that impairment reversed from probable to possible ADRD. Findings support previous evidence that certain activities may slow or reverse cognitive decline and can inform future studies exploring the causality of dementia onset.

A New Normal? Continued Impact of COVID19 on Alzheimer’s Clinical Trials Research

The COVID-19 pandemic has led to unprecedented challenges in Alzheimer’s disease and related dementias (ADRD) clinical trials research. Scientists continue to grapple with the potential and multifaceted consequences of COVID-19. This presentation will discuss strategies used at a U.S. Alzheimer’s Disease Research Center to implement virtual methods to counter COVID-19’s impact on safety for continued research engagement; address the disparate impact by age, race, and ethnicity for online accessibility; and plans for virtual engagement in future research. As scientists navigate lasting implications of COVID-19, future study planning, design, and management will likely be altered. Specifically, increased awareness of participant-centered approaches, inclusion of psychosocial implications, and focus on ways to meet older adults’ unique needs of virtual accessibility will be needed. We must be intentional to counter COVID-19’s lasting impact on ADRD clinical trials research while maintaining rigor and reproducibility to uphold and progress advances toward treatment and cures for ADRD.

A policy mapping analysis of the U.S. Congressional approach to medical aid-in-dying

Oregon was the first state to legalize medical aid-in-dying (MAID), in 1994. Since then eight states and Washington, DC have legalized MAID through legislation. Despite literature exploring the legal and ethical aspects of MAID, very little research examines MAID policy at the federal level. This study aimed to 1) examine the objectives of MAID legislation introduced to the US Congress, and 2) investigate whether these bills increase or decrease access to MAID. This study used the congress.gov website to search for bills related to MAID introduced by the US Congress between 1994 and 2020. From the 98 bills identified, we excluded bills that were not directly related to MAID or were introduced in subsequent congresses. In total, 23 bills were retained and analyzed. The greatest number of bills aimed to restrict funds for MAID, followed by bills that sought to regulate the drugs used for MAID. Other bills prohibited the development of policies supporting MAID, regulated penalties for practitioners related to the drugs used for MAID, and restricted legal assistance for accessing MAID. These bills intended to block or limit patient access to MAID by restricting drugs, funds, health care services, legal assistance, policy, and research. These findings suggest that the federal approach is incongruous with the growing numbers of states that have legalized MAID. Federal policymakers must develop policies to 1) prevent discrimination against vulnerable groups, 2) support funds to study MAID, and 3) build a system to allows eligible individuals to access MAID equally.

Exploring older adults' experiences using technology during a viral pandemic

Background

Older adults are at greater risk for morbidity and mortality associated with COVID‐19. Spatial distancing and sequestering practices are recommended to limit viral exposure. Older adults adopting these practices are at increased risk of social isolation and adverse health outcomes. Remote technologies offer various platforms for satisfying socialization and healthcare needs while sequestering. Understanding how older adults are using technology has implications for wellbeing during a pandemic.

Method

Researchers attempted to contact all participants enrolled in the University of Kentucky Alzheimer's Disease Research Center longitudinal study via telephone to survey technology use (n = 706). Participants were contacted directly, except for demented participants, whose primary caregivers were contacted to respond on their behalf, when possible. Participants and caregivers gave their assent verbally to complete the voluntary survey, the procedures of which were approved by the IRB. The surveys consisted of validated instruments to gauge the extent of use of and comfort with technology. Spearman correlations, chi‐square tests, and t‐tests were used to explore data.

Result

Ultimately, 384 participants were reached and 332 consented to participate. Most reported reliable home internet access (91.5%) and some internet use (90.6%). Recent feelings of loneliness were not related to any technology‐related variables (all ps > 0.29) other than decreasing with greater willingness to use telehealth (Rho = ‐0.11, p = 0.06). Those who reported a lack of comfort with technology (n = 76) were less likely to text messaging (67% vs 78%) and social media (56% vs 69%), ps ≤ 0.06, but felt socially connected using technology at similar levels (82% vs 75%), p = 0.22. Nearly 70% of this group reported they would use technology more with training. Across all participants, willingness to use telehealth was not related to frequency of frustration with tech (Rho = 0, p = 0.99).

Conclusion

The results suggest that some older adults’ use of technology is limited by familiarity. Lack of familiarity does not appear to create a barrier to using telehealth nor does frustration with technology appear to limit telehealth use. The findings have implications for supporting older adults sequestered during a pandemic but potentially more broadly.

Anticoagulation after Spontaneous Intraparenchymal Hemorrhage in Patients with Mechanical Heart Valves and Concomitant Atrial Fibrillation

Aim Patients with mechanical heart valves and coexisting atrial fibrillation (AFib-MHV) who suffer an intraparenchymal hemorrhage (IPH, defined as bleeding solely within the brain parenchyma and/or ventricle) are at a high risk of thromboembolism without anticoagulation. Data are lacking regarding the safety of early re-initiation of anticoagulation in these patients.

Patients and Methods We performed a descriptive, single-institution retrospective analysis of patients with AFib-MHV who suffered a non-traumatic, supratentorial IPH between July 2013 and June 2017. We analyzed the patients and IPH characteristics, anticoagulation and antiplatelet use, the occurrence of thrombotic and hemorrhage complications, and discharge disposition. We described the timing of initiation of anticoagulation and outcomes after IPH while in-patient.

Results Six patients with AFib-MHV suffered a spontaneous IPH. Four were initiated on anticoagulation prior to discharge, of whom two were initiated within 3 days post-hemorrhage. These patients suffered no bleeding complications and were discharged home with a modified Rankin Scale of 1.

Conclusion Patients with AFib-MHV who suffer a spontaneous IPH are a rare population to study. Further studies to guide the management of restarting anticoagulation in this select population are warranted.

Rural Older Adults in Disasters: A Study of Recovery From Hurricane Michael

OBJECTIVE

This study aims for a greater understanding of how older adults (age 65 and older) in Jackson County, Florida, are prepared for and cope with the effects of a natural disaster.

METHODS

A multidisciplinary, international research team developed a survey examining: (1) resources available to individuals aged 65+ in rural communities for preparing for a disaster; (2) challenges they face when experiencing a disaster; and (3) their physical, social, emotional, and financial needs when it strikes. The survey was administered with older adults (65+) in Jackson County, Florida, following Hurricane Michael in 2018. The descriptive, multivariate logistic, and linear regression analyses were performed to examine the relationship between respondents' demographic information and needs, concerns, and consequences of disaster.

RESULTS

Results indicated (n = 139) rural community-dwelling older adults rely on social support, community organizations, and trusted disaster relief agencies to prepare for and recover from disaster-related events.

CONCLUSIONS

Such findings can be used to inform the development of new interventions, programs, policies, practices, and tools for emergency management and social service agencies to improve disaster preparedness and resiliency among older populations in rural communities.

1316 An Evaluation of The Consent Process in One of The Largest Spinal Surgery Units in Europe

Complex spinal surgery has high morbidity and mortality making the process of consent central to patient care [1]. Our aim was to qualitatively assess our consent process with three set metrics; how far in advance patients were consented prior to the date of surgery, the inclusion of all relevant risks on the consent form and the provision of supplementary patient information leaflets or equivalent.

We retrospectively reviewed 100 consecutive patients undergoing elective spinal surgery at our tertiary centre which is the one of the largest spinal units in Europe between December 2019 and March 2020.

All patients had valid consent forms. 16% of patients were consented on the day of surgery, 22% were consented the day before. Of the remaining 62%, 22 patients (35%) were consented within 2 weeks of surgery, and 40 (65%) over 2 weeks prior to surgery.

94% were consented for all relevant risks as determined by the senior authors. 81% had no documentation of receiving supplementary information and 11% had documentation of consent discussion in clinic.

In conclusion, this audit revealed a significant variation in the consent process within our unit. This may highlight a deficit in the consenting process which we aim to explore further.
