Project description:Sociality-i.e., life in social groups-has evolved many times in rodents, and there is considerable variation in the nature of these groups. While many species-typical behaviors have been described in field settings, the use of consistent behavioral assays in the laboratory provides key data for comparisons across species. The preference for interaction with familiar or novel individuals is an important dimension of social behavior. Familiarity preference, in particular, may be associated with more closed, less flexible social groups. The dimension from selectivity to gregariousness has been used as a factor in classification of social group types. Laboratory tests of social choice range from brief (10 minutes) to extended (e.g., 3 hours). As familiarity preferences typically need long testing intervals to manifest, we used 3-hour peer partner preference tests to test for the presence of familiarity preferences in same-sex cage-mates and strangers in rats. We then conducted an aggregated analysis of familiarity preferences across multiple rodent species (adult male and female rats, mice, prairie voles, meadow voles, and female degus) tested with the same protocol. We found a high degree of consistency within species across data sets, supporting the existence of strong, species-typical familiarity preferences in prairie voles and meadow voles, and a lack of familiarity preferences in other species tested. Sociability, or total time spent near conspecifics, was unrelated to selectivity in social preference. These findings provide important background for interpreting the neurobiological mechanisms involved in social behavior in these species.

Project description:ObjectivesTo describe the association between parents' attention-deficit/hyperactivity disorder (ADHD) treatment preferences and goals and treatment initiation.MethodsParents/guardians of children aged 6 to 12 years diagnosed with ADHD in the past 18 months and not currently receiving combined treatment (both medication and behavior therapy [BT]) were recruited from 8 primary care sites and an ADHD treatment center. Parents completed the ADHD Preference and Goal Instrument, a validated measure, and reported treatment receipt at 6 months. Logistic regression was used to analyze the association of baseline preferences and goals with treatment initiation. Using linear regression, we compared the change in preferences and goals over 6 months for children who initiated treatment versus others.ResultsThe study included 148 parents/guardians. Baseline medication and BT preference were associated with treatment initiation (odds ratio [OR]: 2.6 [95% confidence interval (CI):1.2-5.5] and 2.2 [95% CI: 1.0-5.1], respectively). The goal of academic achievement was associated with medication initiation (OR: 2.1 [95% CI: 1.3-3.4]) and the goal of behavioral compliance with initiation of BT (OR: 1.6 [95% CI: 1.1-2.4]). At 6 months, parents whose children initiated medication or BT compared with others had decreased academic and behavioral goals, suggesting their goals were attained. However, only those initiating BT had diminished interpersonal relationship goals.ConclusionsParental treatment preferences were associated with treatment initiation, and those with distinct goals selected different treatments. Results support the formal measurement of preferences and goals in practice as prioritized in recent national guidelines for ADHD management.

Project description:Solitary insects that feed on floral nectar must use innate knowledge to find their first flower. While innate preferences for flower colours are often described as fixed, species-specific traits, the nature and persistence of these preferences have been debated, particularly in relation to ontogenetic processes such as learning. Here we present evidence for a strong context-dependence of innate colour preferences in the crepuscular hawkmoth Manduca sexta. Contrary to expectations, our results show that innate colour biases shift with changes in the visual environment, namely illuminance and background. This finding reveals that innate responses might emerge from a contextual integration of sensory inputs involved in object class recognition rather than from the deterministic matching of such inputs with a fixed internal representation.

Project description:ImportanceOlder adults with multiple chronic conditions (MCCs) vary in their health outcome goals and the health care that they prefer to receive to achieve these goals.ObjectiveTo describe the outcome goals and health care preferences of this population with MCCs.Design, setting, and participantsThis cross-sectional study included participants in the Patient Priorities Care study who underwent health priorities identification from February 1, 2017, to August 31, 2018, in a primary care practice. Patients eligible to participate were 65 years or older, English speaking, and had at least 3 chronic conditions; in addition, they used at least 10 medications, saw at least 2 specialists, or had at least 2 emergency department visits or 1 hospitalization during the past year. Of 236 eligible patients, 163 (69%) agreed to participate in this study. Data were analyzed from August 1 to October 31, 2020.ExposuresGuided by facilitators, participants identified their core values, as many as 3 actionable and realistic outcome goals, health-related barriers to these goals, and as many as 3 helpful and 3 bothersome health care activities.Main outcomes and measuresFrequencies were ascertained for outcome goals and health care preferences. Preferences included health care activities (medications, health care visits, procedures, diagnostic tests, and self-management) reported as either helpful or bothersome.ResultsMost of the 163 participants were White (158 [96.9%]) and women (109 [66.9%]), with a mean (SD) age of 77.6 (7.6) years. Of 459 goals, the most common encompassed meals and other activities with family and friends (111 [24.2%]), shopping (28 [6.1%]), and exercising (21 [4.6%]). Twenty individuals (12.3%) desired to live independently without specifying necessary activities. Of 312 barriers identified, the most common were pain (128 [41.0%]), fatigue (45 [14.4%]), unsteadiness (42 [13.5%]), and dyspnea (19 [6.1%]). Similar proportions of patients identified at least 1 medication that was helpful (130 [79.8%]) or bothersome (128 [78.5%]). Medications most commonly cited as helpful were pain medications, including nonopiods (36 of 55 users [65.5%]) and opioids (15 of 27 users [55.6%]); sleep medications (27 of 51 users [52.9%]); and respiratory inhalants (19 of 45 [42.2%]). Most often mentioned as bothersome were statins (25 of 97 users [25.8%]) and antidepressants (13 of 40 users [32.5%]). Thirty-two participants (19.6%) reported using too many medications. Health care visits were identified as helpful by 43 participants (26.4%); 15 (9.2%) reported too many visits. Procedures were named helpful by 38 participants (23.3%); 24 (14.7%) cited unwanted procedures. Among 48 participants with diabetes, monitoring of glucose levels was doable for 18 (37.5%) and too bothersome for 9 (18.8%).Conclusions and relevanceParticipants identified realistic and actionable goals while varying in health care activities deemed helpful or bothersome. The goals and health care preferences of more diverse populations must be explored. Previous work suggests that clinicians can use this information in decision-making.

Project description:The propensity of protein sites to be occupied by any of the 20 amino acids is known as site-specific amino acid preferences (SSAP). Under the assumption that SSAP are conserved among homologs, they can be used to parameterize evolutionary models for the reconstruction of accurate phylogenetic trees. However, simulations and experimental studies have not been able to fully assess the relative conservation of SSAP as a function of sequence divergence between protein homologs. Here, we implement a computational procedure to predict the SSAP of proteins based on the effect of changes in thermodynamic stability upon mutation. An advantage of this computational approach is that it allows us to interrogate a large and unbiased sample of homologous proteins, over the entire spectrum of sequence divergence, and under selection for the same molecular trait. We show that computational predictions have reproducibilities that resemble those obtained in experimental replicates, and can largely recapitulate the SSAP observed in a large-scale mutagenesis experiment. Our results support recent experimental reports on the conservation of SSAP of related homologs, with a slowly increasing fraction of up to 15% of different sites at sequence distances lower than 40%. However, even under the sole contribution of thermodynamic stability, our conservative approach identifies up to 30% of significant different sites between divergent homologs. We show that this relation holds for homologs of diverse sizes and structural classes. Analyses of residue contact networks suggest that an important determinant of these differences is the increasing accumulation of structural deviations that results from sequence divergence.

Project description:BackgroundListening to patient voices is critical, in terms of how people experience their condition as well as their treatment preferences. This research explored the patient journey, therapy attributes and goals among treatment experienced adults with chronic lymphocytic leukemia (CLL). We sought to understand patient experiences, needs and expectations to identify areas for improvement of treatment and care delivery.MethodsTwo online surveys were developed for completion by CLL patients. In Stage 1, participants completed a best-worst scaling (BWS) task to evaluate eleven previously validated healthcare journey moments that matter (MTM). Responses were used to generate the patient experience index (PEI) score. In Stage 2, participants completed a survey that included both a discrete choice experiment (DCE) to assess drivers of treatment preferences by evaluating the relative attribute importance (RAI) of seven features and a BWS exercise which explored long-term treatment goals.ResultsTwenty-five patients completed Stage 1 and thirty patients Stage 2. Treatment experience was balanced between oral and intravenous medication. The most important/least satisfied MTM were treatment effectiveness, access to support and other treatments as well as monitoring progress. The median PEI score was 66.2 (out of 100). DCE results demonstrated that patients most value treatments for CLL that are associated with prolonged progression free survival (PFS; RAI: 24.6%), followed by treatments that have a lower risk of severe side effects and lower out-of-pocket costs (RAI: 19.5%, 17.4%, respectively). The remainder of the weight in decision making (38.5%) was split between the remaining attributes, namely 'mild to moderate side effects' (13.4%), 'long-term risks' (12.2%), type of treatment (i.e., oral, IV or a combination of oral and IV; 8.7%) and treatment duration (i.e., ongoing versus fixed; 4.2%). Patients preferred oral to intravenous therapy. The most valued long-term treatment goal was to be physically healthy, followed by living a long life, spending time with family/friends, and avoiding hospitalization.ConclusionTreatment experienced patients with CLL are focused on receiving effective, safe therapies and value long PFS. Consideration and discussion of other attributes, such as once daily dosing, oral only medication, out-of-pocket costs and access to support services may affect patient treatment choices and ultimately enhance their healthcare experience and outcomes.

Project description:OBJECTIVES:To describe the development and validation of an instrument to measure parents' attention deficit-hyperactivity disorder (ADHD) treatment preferences and goals. METHODS:Parents of children 6 to 12 years of age diagnosed with ADHD in the past 18 months were recruited from 8 primary care sites and an ADHD treatment center (autism excluded). A 16-item medication, 15-item behavior therapy preference scale and a 23-item goal scale, were developed after a review of the literature, 90 parent and clinician semistructured interviews, and input from parent advocates and professional experts were administered to parents. Parent cognitive interviews confirmed item readability, clarity, content, and response range. We conducted an exploratory factor analysis and assessed internal consistency and test-retest reliability and construct and concurrent validity. RESULTS:We recruited 237 parents (mean child age 8.1 years, 51% black, 59% from primary care, 61% of children medication naive). Factor analyses identified 4 medication preference subscales (treatment acceptability, feasibility, stigma, and adverse effects, Cronbach's ? 0.74-0.87); 3 behavior therapy subscales (treatment acceptability, feasibility, and adverse effects, ? 0.76-0.83); and 3 goal subscales (academic achievement, behavioral compliance, and interpersonal relationships, ? 0.83-0.86). The most strongly endorsed goal was academic achievement. The scales demonstrated construct validity, concurrent validity (r = 0.3-0.6) compared with the Treatment Acceptability Questionnaire and Impairment Rating Scale and moderate to excellent test-retest reliability (intraclass coefficient = 0.7-0.9). CONCLUSIONS:We developed a valid and reliable instrument for measuring preferences and goals for ADHD treatment, which may help clinicians more easily comply with new national treatment guidelines for ADHD that emphasize shared decision making.

Project description:The Ramachandran plot distributions of nonglycine residues from experimentally determined structures are routinely described as grouping into one of six major basins: β, PII , α, αL , ξ and γ'. Recent work describing the most common conformations adopted by pairs of residues in folded proteins [i.e., (φ,ψ)2 -motifs] showed that commonly described major basins are not true single thermodynamic basins, but are composed of distinct subregions that are associated with various conformations of either the preceding or following neighbor residue. Here, as documentation of the extent to which the conformational preferences of a central residue are influenced by the conformations of its two neighbors, we present a set of φ,ψ-plots that are delimited simultaneously by the φ,ψ-angles of its neighboring residues on both sides. The level of influence seen here is typically greater than the influence associated with considering the identities of neighboring residues, implying that the use of this heretofore untapped information can improve the accuracy of structure prediction algorithms and low resolution protein structure refinement.

Project description:In cognitive psychology novelty is an antecedent of attention, emotion, memory, and behavior. However, the relationship between novelty and experience memorability remains conceptually underdeveloped in tourism. This research applies cognitive appraisal theory (CAT) to explore the contribution of novelty and emotion to memorable tourism experiences (MTEs). Seventy-five novel travel episodes were identified through semi-structured interviews. Analysis focused on the antecedent and consequent conditions of novelty. Novel experiences, whether positive or negative, were identified as critical to experience memorability. Novelty could be segmented into trip-related and event-related dimensions. Novelty contributes to how spatial, temporal, and contextual details of tourism experiences are remembered and reconstructed due to the elicitation of intense emotions. Analysis revealed negative experiences deemed as novel were found to be re-evaluated and often remembered as a positive experience. A conceptual model titled "cognitive appraisal of novelty in memorable tourism experiences" is presented for consideration in future research. By applying a retrospective and prospective approach the conceptual model explores the role of novelty through the process of cognitive appraisal, identifying goals, attention, and prior experiences as central for the experience of novelty. Future research should consider the application of recent advance in CAT to advance inquiry on tourism experiences as a psychological phenomenon.

Project description:"Novelty-seeking" behavior describes the variability of rats' locomotor response, namely high and low responders (HR and LR respectively), when exposed to a novel environment. Novelty-seeking in the rat is considered to model "sensation-seeking" in humans, a personality trait related to substance abuse. It is assumed that HR rats and LR rats differ in their emotional reactivity because of the disparate incentive value of contextual stimulus, thus differentially interacting with their environment. However, little is known about how HR and LR rats recognize novelty arising from the environment. The present study evaluates whether phenotype may affect spontaneous, non-spatial novelty discrimination. Selectively bred HR and LR rats were submitted to the novel-object recognition test. The task involved a delay of 3h after a first encounter with an object ("old"), which had to be discriminated from a second object ("new"). Object discrimination was assessed minute-by-minute during a 3-min choice session. Amnesic effects of scopolamine (0.5mg/kg, intraperitoneal) were also analyzed. HR-bred rats showed sustained novel-object recognition throughout the 3-min choice session, whereas LR-bred rats began to discriminate between objects only in the last minute. Surprisingly, level of discrimination in scopolamine-treated HR-bred rats was significant during the first minute of the choice test and diminished thereafter, presumably because both objects became equally familiar as they were explored. Additionally, scopolamine induced changes in muscarine M(2) receptor gene expression in a phenotype-dependent manner. Because consistent object discrimination mainly arises during the first minute, these findings may reflect differential novelty detection in HR-bred respect to LR-bred rats.
