Title: Abandoning the Dead Donor Rule?: A National Survey of Public Views on Death and Organ Donation.
Creator: Nair-Collins, Michael, Green, Sydney, Sutin, Angelina
Abstract/Description: Brain dead organ donors are the principal source of transplantable organs. However, it is controversial whether brain death is the same as biological death. Therefore, it is unclear whether organ removal in brain death is consistent with the 'dead donor rule', which states that organ removal must not cause death. Our aim was to evaluate the public's opinion about organ removal if explicitly described as causing the death of a donor in irreversible apneic coma. We conducted a cross-sectional...
Show moreBrain dead organ donors are the principal source of transplantable organs. However, it is controversial whether brain death is the same as biological death. Therefore, it is unclear whether organ removal in brain death is consistent with the 'dead donor rule', which states that organ removal must not cause death. Our aim was to evaluate the public's opinion about organ removal if explicitly described as causing the death of a donor in irreversible apneic coma. We conducted a cross-sectional internet survey of the American public (n=1096). Questionnaire domains included opinions about a hypothetical scenario of organ removal described as causing the death of a patient in irreversible coma, and items measuring willingness to donate organs after death. Some 71% of the sample agreed that it should be legal for patients to donate organs in the scenario described and 67% agreed that they would want to donate organs in a similar situation. Of the 85% of the sample who agreed that they were willing to donate organs after death, 76% agreed that they would donate in the scenario of irreversible coma with organ removal causing death. There appears to be public support for organ donation in a scenario explicitly described as violating the dead donor rule. Further, most but not all people who would agree to donate when organ removal is described as occurring after death would also agree to donate when organ removal is described as causing death in irreversible coma.

Title: Allostatic Load and Personality: A 4-Year Longitudinal Study..
Creator: Stephan, Yannick, Sutin, Angelina R, Luchetti, Martina, Terracciano, Antonio
Abstract/Description: Dysregulation across multiple physiological systems, referred to as allostatic load, has pervasive consequences for an individual's health. The present study examined whether allostatic load is associated with personality and personality changes during a 4-year follow-up. A total of 5200 participants aged from 50 to 99 years (59.5% women, mean [standard deviation] age = 66.91 [8.88] years) from the Health and Retirement Study provided data on cardiovascular, metabolic, and immune markers at...

The present study examined whether allostatic load is associated with personality and personality changes during a 4-year follow-up. A total of 5200 participants aged from 50 to 99 years (59.5% women, mean [standard deviation] age = 66.91 [8.88] years) from the Health and Retirement Study provided data on cardiovascular, metabolic, and immune markers at baseline and personality both at baseline and at 4 years later. Higher allostatic load was related to higher neuroticism (β = 0.03, p = .042), lower extraversion (β = -0.06, p < .001), and lower conscientiousness (β = -0.06, p < .001) at baseline, and to declines in extraversion (β = -0.03, p = .007), conscientiousness (β = -0.04, p < .001), and agreeableness (β = -0.02, p = .020) over the 4-year period, controlling for demographic covariates. A significant quadratic relation between allostatic load and changes in openness (β = -0.03, p = .002) suggested that openness declines when individuals exceed a high level of cumulative physiological dysregulation. No association was found with changes in neuroticism. Allostatic load is associated with personality change across adulthood and old age. The findings indicate that physiological dysregulation across multiple systems challenges personality stability and is associated with accelerated personality traits change.

Program spreadsheets listing the dates for delivery and number of attendees were also reviewed. Overall, evaluation findings were positive. In the 2011-2012 program year, 16 different course sessions were offered, and more than half of enrolled participants came from Title I schools. A total of 228 people were trained. In the 2012-2013 program year, 19 different course sessions were offered. Enrollment totals (638) and matching pre- and posttest totals (562) soundly exceeded the target metric of 425. At least 170 (27%) of a total of 638 participants could be verified as coming from the target demographic of Title I school faculty and staff. In the 2013-2014 program year, the course was offered online on a rolling basis via the Florida TRAIN course management system. Enrollment remained high and learner outcomes remained consistently strong across all content areas for knowledge and satisfaction. A total of 406 people participated in the training; complete pre- and posttest data were available for 341 of these individuals; and satisfaction data were available for 325. Of the 406 trainees, 199 (49%) reported working for Title I schools. Evaluation yielded very positive results. An overwhelming majority of participants reported finding the course consistently strong across the board and highly impactful for their own ability to help students manage their asthma effectively. Most participants also reported that they would change/improve their asthma management behaviors in the workplace. Recommendations were developed to help expand future program reach.

Show moreAmputation is a traumatic and life-changing event that can take years to adjust to. The present study (a) examines psychological adjustment in a specific trauma-exposed sample, (b) compares the phenomenology (e.g., vividness) of amputation-related memories to more recent memories, and (c) tests whether memory phenomenology is associated with psychological distress. A total of 24 upper-limb amputees recalled two autobiographical memories–an amputation-related memory and a recent memory–and rated the phenomenological qualities of each memory, including Vividness, Coherence, Emotional Intensity, Visual Perspective, and Distancing. Participants also completed self-rated measures of psychological distress and personality. The sample was generally well adjusted; participants showed no relevant symptoms of anxiety and depression, and personality scores were similar to the general population. There were no significant differences in phenomenology between the two types of memories recalled. Even though amputation-related memories were, on average, almost 20 years older than the recent memories, they retained their intense phenomenology. Despite the intensity of the memory, none of the phenomenological dimensions were associated with psychological distress. It is worth to further define which dimensions of phenomenology characterize memories of traumatic events, and their association with individuals' psychological reactions.

Abstract/Description: In two studies, the present research tested the phenomenology and content of autobiographical memory as distinct mediators between attachment avoidance and anxiety and depressive symptoms. In Study 1, participants (N = 454) completed measures of attachment and depressive symptoms in one session, and retrieved and rated two self-defining memories of romantic relationships in a separate session.

Show moreIn two studies, the present research tested the phenomenology and content of autobiographical memory as distinct mediators between attachment avoidance and anxiety and depressive symptoms. In Study 1, participants (N = 454) completed measures of attachment and depressive symptoms in one session, and retrieved and rated two self-defining memories of romantic relationships in a separate session. In Study 2, participants (N = 534) were primed with attachment security, attachment insecurity, or a control prime and then retrieved and rated a self-defining relationship memory. Memory phenomenology, specifically memory coherence and emotional intensity, mediated the association between attachment avoidance and depressive symptoms, whereas the negative affective content of the memory mediated the association between attachment anxiety and depressive symptoms. Priming attachment security led to retrieval of a more coherent relationship memory, whereas insecurity led to the retrieval of a more incoherent relationship memory. Discussion focuses on the construction and recollection of memories as underlying mechanisms of adult attachment and psychological distress, the importance of memory coherence, and the implications for counseling research and practice.

Show moreThere are three primary purposes to this booklet. The first is to introduce you to the basic tenets of professionalism. The second is to provide an introduction to the general orientation toward patient care that we teach here at the FSU College of Medicine. This is a patient-centered form of care, with an emphasis on the biopsychosocial model of health and illness. The third purpose is to provide an introduction to some of the specific skills necessary to conduct effective patient interviews. Although these three areas may seem distinct from one another, in fact they are deeply intertwined. We strongly encourage you to approach these three domains in an integrated fashion. You will have many opportunities to practice the skills described in this booklet. For example, we frequently use role-playing exercises to give you a chance to practice the skills that are necessary to conduct effective medical interviews. In these exercises, you will have the opportunity to interact with your classmates, medical school faculty, and trained "standardized patients" in pre-defined scenarios. Although this might initially feel awkward, research demonstrates that these types of learning experiences can be very valuable for those who take them seriously. The more you practice the more effective you will be when you do the "real thing." You will also be expected to behave in a professional manner from your first day as a medical student. It is important that you take this aspect of your education seriously. Professional behavior is fundamental to good medical practice, and the time to begin acting professionally is now. Your understanding of the skills and approaches outlined in this booklet, and your ability to use them, will be assessed frequently throughout your training as a student at FSU College of Medicine. We are confident that these skills and approaches to the practice of medicine will help you become a confident and effective interviewer.

Show moreBrain-derived neurotrophic factor (BDNF) regulates synaptic plasticity and neurotransmission, and has been linked to neuroticism, a major risk factor for psychiatric disorders. A recent genome-wide association (GWA) scan, however, found the BDNF Val66Met polymorphism (rs6265) associated with extraversion but not with neuroticism. In this study, we examine the links between BDNF and personality traits, assessed using the Revised NEO Personality Inventory (NEO-PI-R), in a sample from SardiNIA (n=1560) and the Baltimore Longitudinal Study of Aging (BLSA; n=1131). Consistent with GWA results, we found that BDNF Met carriers were more introverted. By contrast, in both samples and in a meta-analysis inclusive of published data (n=15251), we found no evidence for a main effect of BDNF Val66Met on neuroticism. Finally, on the basis of recent reports of an epistatic effect between BDNF and the serotonin transporter, we explored a Val66Met x 5-HTTLPR interaction in a larger SardiNIA sample (n=2333). We found that 5-HTTLPR LL carriers scored lower on neuroticism in the presence of the BDNF Val variant, but scored higher on neuroticism in the presence of the BDNF Met variant. Our findings support the association between the BDNF Met variant and introversion and suggest that BDNF interacts with the serotonin transporter gene to influence neuroticism.

Show moreThe controversy surrounding the dead donor rule and the adequacy of neurological criteria for death continues unabated. However, despite disagreement on fundamental theoretical questions, I argue that there is significant (but not complete) agreement on the permissibility of organ retrieval from heart-beating donors. Many disagreements are rooted in disputes surrounding language meaning and use, rather than the practices of transplant medicine. Thus I suggest that the debate can be fruitfully recast in terms of a dispute about language. Given this recasting, I argue that the language used to describe organ donation is misleading and paternalistic. Finally, I suggest that the near-agreement on the permissibility of heart-beating organ retrieval ought to be reconsidered. If the paternalism is not justified, then either the language used to describe organ transplantation must change radically, or it would seem to follow that much of the transplant enterprise lacks ethical justification.

Caregivers recruited from paediatricians' offices (n = 453) completed a survey about childhood health; nurses weighed and measured the children. Caregivers reported their own weight and height, demographic information about their family and made ratings of healthy weight for children in general and for their own child in particular. African American caregivers were more likely to view heavier girls as healthier, but this association held only for lower income families or caregivers with higher body mass index. Hispanic caregivers were more likely to misperceive their own child's weight if either the caregiver or the child had a higher body mass index. Parents who perceived heavier weight as healthier or misperceived their own child's weight were more likely to have a child with obesity. This latter association held regardless of ethnicity. The association between ethnicity and perceptions of healthy childhood weight are complex. The relation between caregivers' perceptions of healthy weight and their own child's obesity status, however, was similar regardless of ethnicity.

To identify the psychological factors associated with dyslipidemia, this study investigates the personality correlates of cholesterol (total, LDL, and HDL) and triglycerides. A community-based sample (N=5532) from Sardinia, Italy, had their cholesterol and triglyceride levels assessed and completed a comprehensive personality questionnaire, the NEO-PI-R. All analyses controlled for age, sex, BMI, smoking, drinking, hypertension, and diabetes. Low Conscientiousness and traits related to impulsivity were associated with lower HDL cholesterol and higher triglycerides. Compared to the lowest 10%, those who scored in top 10% on Impulsivity had a 2.5 times greater risk of exceeding the clinical threshold for elevated triglycerides (OR=2.51, CI=1.56-4.07). In addition, sex moderated the association between trait depression (a component of Neuroticism) and HDL cholesterol, such that trait depression was associated with lower levels of HDL cholesterol in women but not men. When considering the connection between personality and health, unhealthy lipid profiles may be one intermediate biomarker between personality and morbidity and mortality.

Show moreBACKGROUND: This study explores relationships between chronic inflammation and quality of life, making a case for biopsychosocial modeling of these associations. It builds on research from social and clinical disciplines connecting chronic conditions, and inflammatory conditions specifically, to reduced quality of life. METHODS: Data from Wave I of the National Social Life, Health, and Aging Project are modeled using ordinal logistic and ordinary least-squares regression techniques. Inflammation is measured using C-reactive protein; quality of life is conceptualized as happiness with life overall as well as intimate relationships specifically. RESULTS: For most NSHAP participants, chronic inflammation significantly predicts lower odds of reporting high QoL on both emotional and relational measures. Social structural factors do not confound these associations. Inconsistent results for participants with very high (over 6 mg/L) CRP measurements suggest additional social influences. CONCLUSIONS: Findings echo strong theoretical justification for investigating relationships between CRP and QoL in greater detail. Further research should explore possible mediation of these associations by sociomedical sequelae of chronic disease as well as social relationship dynamics. Elaboration is also needed on the mechanisms by which social disadvantage may cause chronic inflammation.

Each volunteering, consenting senior was placed into one of two groups: walking tours outside, then discussions (n=37); and focus group discussions indoors about photographs of BE conditions potentially influencing mobility (n=43). The authors sought to identify BE factors-both real and perceived by participating seniors-related to their ability to walk around senior wellness centers in a healthy and safe manner. The authors focused specifically on available literature and pilot study data for their concept of "safe senior zones" around senior wellness centers serving urban communities in this article. They also characterized their study population regarding sociodemographic variables and doctor-diagnosed chronic diseases, and types of walking aids reported used to help prevent falls. Their results can inform future applied practice and research on traffic-related exposures and BE factors concerning seniors, and support policy and planning to benefit community environmental public health.

However, regression models in general examine the average effects of the risk factors and ignore subgroups with different risk profiles. As a result, interventions are often geared towards the average member of the population, without consideration of the special health needs of different subgroups within the population. This paper demonstrates the value of using rule-based analysis methods that can identify subgroups with heterogeneous risk profiles in a population without imposing assumptions on the subgroups or method. The rules define the risk pattern of subsets of individuals by not only considering the interactions between the risk factors but also their ranges. We compared the rule-based analysis results with the results from a logistic regression model in The Environmental Determinants of Diabetes in the Young (TEDDY) study. Both methods detected a similar suite of risk factors, but the rule-based analysis was superior at detecting multiple interactions between the risk factors that characterize the subgroups. A further investigation of the particular characteristics of each subgroup may detect the special health needs of the subgroup and lead to tailored interventions.

Show moreThe aims of this study were to describe complementary and alternative medicine (CAM) use and to assess the relationships between CAM use and antiretroviral therapy (ART) adherence and human immunodeficiency virus (HIV) RNA viral load suppression among a sample of persons living with HIV (PLWH) engaged in care in the state of Florida. The Florida Medical Monitoring Project (n = 803) collected repeated cross-sectional data for surveillance of clinical outcomes among PLWH from 2009 to 2010. Past-year CAM use specifically for the management of HIV was measured via self-report. Logistic regression models were conducted to assess the effect of CAM use on ART adherence and viral load suppression, controlling for demographic and clinical factors using backwards stepwise deletion of factors with a p-value of >0.25. CAM use was reported in 53.3% (n = 428). In bivariate analysis, CAM use was the highest among those 40-49 years of age (61%; p < 0.05), males (56%; p < 0.01), whites (61%; p = 0.001), and those educated beyond high school (59%; p < 0.05). Among those using CAM, 63% and 37% reported one and two or more CAM modalities, respectively. CAM modalities included biologically based therapies (89%), mind-body medicine/manipulative body-based therapies (30%), spiritual healing (23%), energy therapies (6%), and whole medical systems (6%). In multivariable analyses, any CAM use and number of CAM methods used were not associated with ART adherence. Any CAM use was not associated with detectable viral load (adjusted odds ratio [aOR] 0.81; 95% confidence interval [CI] 0.58-1.12; p = 0.20). Those using two or more methods had significantly decreased risk for detectable viral load (aOR 0.60; 95% CI 0.39-0.92; p < 0.02). CAM use was not associated with negative effects on ART adherence. CAM users were less likely to have detectable viral load compared with non-users. Future research should focus on CAM use among PLWH not engaged in HIV care and the longitudinal patterns of CAM use and possible effects of long-term health outcomes.

Title: Correlates and Phenomenology of First and Third Person Memories.
Creator: Sutin, Angelina, Robins, Richard W.
Abstract/Description: The present research addressed fundamental questions about the visual perspective of autobiographical memories: Are stable personality characteristics associated with visual perspective? Does visual perspective influence the memory's phenomenological qualities?

Show moreThe present research addressed fundamental questions about the visual perspective of autobiographical memories: Are stable personality characteristics associated with visual perspective? Does visual perspective influence the memory's phenomenological qualities? Participants in Study 1 (N=1684) completed individual-difference measures and indicated the perspective from which they generally retrieve memories. Participants in Study 2 (N=706) retrieved a memory from their natural or manipulated perspective, rated its phenomenology, and completed the same individual-difference measures. Dissociation and anxiety were associated with third person retrieval style; the Big Five personality traits were primarily unrelated to perspective. Compared to third person memories, naturally occurring first person memories were higher on Vividness, Coherence, Accessibility, Sensory Detail, Emotional Intensity, and Time Perspective, and lower on Distancing; manipulating perspective eliminated these differences. Visual perspective is associated with clinically relevant constructs and, although associated with the memory's phenomenology, perspective does not shape it.

Show moreUntil recently, awareness of the sexually transmitted infection human papillomavirus (HPV)—the virus that causes cervical cancer—was relatively low. The purpose of this study was to identify factors associated with HPV knowledge now that HPV vaccines have become widely available. Young adult women (n = 739; aged 18-26 years) attending Florida State University who had not yet initiated HPV vaccination completed a survey between March-August 2009. The survey assessed HPV awareness, HPV knowledge, demographics, socio-political variables, sexual history, and health history variables. Over 97% of participants were aware of HPV prior to study enrollment; however, knowledge of HPV was only moderate. A multivariate regression analysis examining factors related to HPV knowledge revealed five independent correlates: Latina ethnicity, premarital sex values, number of lifetime sexual partners, history of cervical dysplasia, and HIV testing. These variables accounted for 14% of the variance in HPV knowledge. Less knowledge was observed for Latinas and women opposed to premarital sex. Greater knowledge was observed for women who had been tested for HIV and women with more sexual partners or a history of cervical dysplasia. These findings can inform future HPV vaccination campaigns and may be particularly useful in developing interventions for individuals with the largest deficits in HPV knowledge.

Title: Depressive Symptoms Are Associated with Weight Gain Among Women.

Show moreBACKGROUND: Many studies have linked depression and obesity; few have more than two assessments of depressive symptoms and adiposity to address the potential bidirectional relationship between adiposity and depressive symptoms from young adulthood through old age. We tested whether baseline depressive symptoms are associated with changes in weight, whether baseline adiposity is associated with changes in depressive symptoms, and whether these associations vary by sex.MethodParticipants (n=2251; 47% female) were from the Baltimore Longitudinal Study of Aging (BLSA). Using hierarchical linear modeling (HLM) on 30 years of data, the trajectory of adiposity and depressive symptoms over adulthood was estimated from >10 000 observations (mean=4.5 assessments per participant) of body mass index (BMI; kg/m2), waist circumference and hip circumference and >10 000 observations (mean=4.5 assessments per participant) of the Center for Epidemiological Studies Depression Scale (CES-D). Baseline depressive symptoms and adiposity were then tested as predictors of the trajectory of adiposity and depressive symptoms respectively. Additional analyses tested for sex-specific associations. RESULTS: Sex moderated the association between depressive symptoms and weight gain such that women who experienced depressed affect had greater increases in BMI (binteraction=0.12, s.e.=0.04), waist (binteraction=0.22, s.e.=0.10) and hip circumference (binteraction=0.20, s.e.=0.07) across the adult lifespan, controlling for relevant demographic and behavioral covariates. Baseline adiposity was unrelated to the trajectory of depressive symptoms (median b=0.00) for both sexes. CONCLUSIONS: Women who experience symptoms of depression tend to gain more weight across adulthood than men who experience such symptoms. Whether an individual was normal weight or overweight was unrelated to changes in depressive symptoms across adulthood.

Show moreBackground: Racial and ethnic minority youth have poorer asthma status than white youth, even after controlling for socioeconomic variables. Proper use of asthma controller medications is critical in reducing asthma mortality and morbidity. The clinical consequences of poor asthma management include increased illness complications, excessive functional morbidity, and fatal asthma attacks. There are significant limitations in research on interventions to improve asthma management in racial minority populations, particularly minority adolescents and young adults, although illness management tends to deteriorate after adolescence during emerging adulthood, the unique developmental period beyond adolescence but before adulthood. Objective: The objective of the pilot study was to test the feasibility, acceptability, and signals of efficacy of an intervention targeting adherence to controller medication in African American youth (ages 18-29) with asthma. All elements of the protocol were piloted in a National Heart, Lung, and Blood Institute (NHLBI)-funded pilot study (1R34HL107664 MacDonell). Results suggested feasibility and acceptability of the protocol as well as proof of concept. We are now ready to test the intervention in a larger randomized clinical trial. Methods: The proposed study will include 192 African American emerging adults with moderate to severe persistent asthma and low controller medication adherence recruited from clinic, emergency department, and community settings. Half of the sample will be randomized to receive a multicomponent technology-based intervention targeting adherence to daily controller medication. The multicomponent technology-based intervention consists of 2 components: (1) 2 sessions of computer-delivered motivational interviewing targeting medication adherence and (2) individualized text messaging focused on medication adherence between the sessions. Text messages will be individualized based on ecological momentary assessment. The remaining participants will complete a series of computer-delivered asthma education modules matched for length, location, and method of delivery of the intervention session. Control participants will also receive text messages between intervention sessions. Message content will be the same for all control participants and contain general facts about asthma (not tailored). Results: It is hypothesized that youth randomized to multicomponent technology-based intervention will show improvements in medication adherence (primary outcome) and asthma control (secondary outcome) compared with comparison condition at all postintervention follow-ups (3, 6, 9, and 12 months). The proposed study was funded by NHLBI from September 1, 2016 through August 31, 2021. Conclusions: This project will test a brief, technology-based intervention specifically targeting adherence to asthma controller medications in an under-researched population, African American emerging adults. If successful, our multicomponent technology-based intervention aimed at improving adherence to asthma medications has the potential to improve quality of life of minority emerging adults with asthma at relatively low cost. It could eventually be integrated into clinical settings and practice to reach a large number of emerging adults with asthma.

A team of health services researchers evaluated both years of the online training. Evaluators used a quasi-experimental design with pretest, posttest, and follow-up assessment. Questions measured knowledge gain and retention, user satisfaction, and implementation of management strategies. Over 650 people from nearly all 67 Florida counties took AFCC training online between 2011 and 2013. Test scores improved by a minimum of 11% points in all program years evaluated. Gains in both knowledge and confidence were substantial and highly significant across years. While individual trainees did forget some content on follow-up, they seemed to retain the specific messages most relevant for their own workplaces. Most trainees also planned to implement multiple management strategies recommended by the training. A large majority of participants rated the training as excellent on all quality metrics, including relevance of content and time efficiency of the online format. Nearly all respondents perceived the training as useful for both providing improved care and fulfilling licensure or certification requirements. Many participants also indicated that their centers would pursue formal certification as AFCCs via the program offered by FAC. The online AFCC course performed strongly in its first years, yielding both high participant satisfaction and substantial improvement in workplace asthma management activity. This training holds promise for introducing and improving multidimensional asthma management strategies at childcare facilities nationwide.

Cross-sectional and longitudinal analyses of two independent samples-one with more than 10,000 repeated assessments across 30 years (mean assessments per participant = 4.44, SD = 3.47) and one with nationally representative data-suggested that well-being declines with age. This decline, however, reversed when we controlled for birth cohort. That is, once we accounted for the fact that older cohorts had lower levels of well-being, all cohorts increased in well-being with age relative to their own baseline. Participants tested more recently had higher well-being, but time of measurement, unlike cohort, did not change the shape of the trajectory. Although well-being increased with age for everyone, cohorts that lived through the economic challenges of the early 20th century had lower well-being than those born during more prosperous times.

The present investigation extends this research to a longitudinal, important domain by exploring the consequences of focusing on one's goals versus accomplishments when pursuing a weight loss goal. Participants were tracked over the course of a 12-week weight loss program that utilized weekly group discussions and a companion website to direct participants' focus toward their end weight loss goal or toward what they had already achieved. Goal-focused participants reported higher levels of commitment to their goal and, ultimately, lost more weight than did accomplishment-focused and no focus control participants. Accomplishment-focused participants did not differ from controls on any measure.

This study examines detailed personality profiles of underweight, normal, and overweight individuals to provide insights into the causes and treatments of abnormal weight. METHODS: More than half of the population from four towns in Sardinia, Italy (n = 5693; age = 14-94 years; mean +/- standard deviation = 43 +/- 17 years) were assessed on multiple anthropometric measures and 30 facets that comprehensively cover the five major dimensions of personality, using the Revised NEO Personality Inventory. RESULTS: High Neuroticism and low Conscientiousness were associated with being underweight and obese, respectively. High Impulsiveness (specifically eating-behavior items) and low Order were associated with body mass index categories of overweight and obese, and with measures of abdominal adiposity (waist and hip circumference). Those scoring in the top 10% of Impulsiveness were about 4 kg heavier than those in the bottom 10%, an effect independent and larger than the FTO genetic variant. Prospective analyses confirmed that Impulsiveness and Order were significant predictors of general and central measures of adiposity assessed 3 years later. CONCLUSIONS: Overweight and obese individuals have difficulty resisting cravings and lack methodical and organized behaviors that might influence diet and weight control. Although individuals' traits have limited impact on the current obesogenic epidemic, personality traits can improve clinical assessment, suggest points of intervention, and help tailor prevention and treatment approaches.

We examined the impact of demographic, lifestyle and psychosocial factors on such non-compliance during the first 3 years of participation in a multidisciplinary prospective paediatric study. Design The Environmental Determinants of Diabetes in the Young (TEDDY) study collects a 3 d food record quarterly during the first year of life and semi-annually thereafter. High compliance with food record completion was defined as the participating families submitting one or more days of food record at every scheduled clinic visit. Setting Three centres in the USA (Colorado, Georgia/Florida and Washington) and three in Europe (Finland, Germany and Sweden). Subjects Families who finished the first 3 years of TEDDY participation (n 8096). Results High compliance was associated with having a single child, older maternal age, higher maternal education and father responding to study questionnaires. Families showing poor compliance were more likely to be living far from the study centres, from ethnic minority groups, living in a crowded household and not attending clinic visits regularly. Postpartum depression, maternal smoking behaviour and mother working outside the home were also independently associated with poor compliance. Conclusions These findings identified specific groups for targeted strategies to encourage completion of food records, thereby reducing potential bias in multidisciplinary collaborative research.

Show moreObjective: Message framing is a theoretically grounded health communication strategy designed to motivate action by emphasizing the benefits of engaging in a particular behavior (gains) or the costs of failing to engage in the behavior (losses). This study investigated whether the effectiveness of a framed message depends on the emotional state of the message recipient. We examined effects of fear versus anger, emotions that frequently occur within the context of health decision-making. Methods: Undergraduate students (N = 133) were randomly assigned to complete a fear or anger induction task after which they read a gain- or loss-framed pamphlet promoting fruit and vegetable consumption. Fruit and vegetable intake (servings per day) was subsequently assessed over the following two weeks. Results: As predicted, a significant frame by emotion interaction was observed, such that participants in the fear condition reported eating more servings of fruits and vegetables after exposure to a loss-framed message than to a gain-framed message. In contrast, participants in the anger condition reported eating (marginally) more servings of fruits and vegetables after exposure to a gain-framed message than to a loss-framed message. That is, greater increases in fruit and vegetable intake from baseline to follow-up were observed when frame was matched to participants' emotional state than when it was mismatched. Conclusion: The effectiveness of framed health communications depends on the message recipient's current emotional state. Affective factors that are incidental to the behavior recommended in a health communication can affect the relative success of gain- and loss-framed appeals.

Show moreSubjective age is a biopsychosocial marker of aging associated with a range of outcomes in old age. In the domain of cognition, feeling older than one's chronological age is related to lower cognitive performance and steeper cognitive decline among older adults. The present study examines whether an older subjective age is associated with the risk of incident cognitive impairment and dementia. Participants were 5,748 individuals aged 65 years and older drawn from the Health and Retirement Study. Measures of subjective age, cognition, and covariates were obtained at baseline, and follow-up cognition was assessed over a 2- to 4-year period. Only participants without cognitive impairment were included at baseline. At follow-up, participants were classified into one of the three categories: normal functioning, cognitive impairment without dementia (CIND), and dementia. An older subjective age at baseline was associated with higher likelihood of CIND (odds ratio [OR] = 1.18; 1.09-1.28) and dementia (OR = 1.29; 1.02-1.63) at follow-up, controlling for chronological age, other demographic factors, and baseline cognition. Physical inactivity and depressive symptoms partly accounted for these associations. An older subjective age is a marker of individuals' risk of subsequent cognitive impairment and dementia.

Show moreBackground and Objectives: A retrospective series and learning curve of the first 101 robotic general surgery cases from a single surgeon in a small community hospital has been previously reported. This study serves as a continuation and offers a more detailed statistical analysis while demonstrating the efficacy and safety of a general surgery robotics program in a community hospital with quality assessment measures. Methods: Measurements included total operative time, console time, conversion rates, complications, surgical site infections, surgical site occurrences, length of stay, and patient demographics. Descriptive statistics were included for all variables. Linear regression was used to test the hypothesis of a learning curve, reflected by a decrease in console time with experience. Results: Between March 2014 and February 2017, 200 robotic general surgery cases were performed by a single surgeon in a 266-bed community hospital, including laparoscopic cholecystectomies; ventral, incisional, and umbilical hernia repairs; colorectal; foregut and bariatric; inguinal hernia repairs; and miscellaneous procedures. One hundred and ninety-eight of the cases (99%) were completed robotically. Thirteen patients were readmitted within 30 days, and 21 had complications (11%). There were no mortalities, and all complications were resolved positively. The mean operative and console times of all 200 cases were 214.8 and 105.7 minutes, respectively. Decreased console time was significantly associated with increasing case load, even after controlling for surgery type. Conclusion: With increased operative volume, general surgeons who utilize the robotic platform can improve operative outcomes, decrease operative times and perform increasingly complicated procedures while maintaining low complication rates.

Subjective well-being, a phenotype that is genetically correlated with both of these traits, has not yet been studied with genome-wide data. We conducted genome-wide association studies of three phenotypes: subjective well-being (n = 298,420), depressive symptoms (n = 161,460), and neuroticism (n = 170,911). We identify 3 variants associated with subjective well-being, 2 variants associated with depressive symptoms, and 11 variants associated with neuroticism, including 2 inversion polymorphisms. The two loci associated with depressive symptoms replicate in an independent depression sample. Joint analyses that exploit the high genetic correlations between the phenotypes (|ρ^| ≈ 0.8) strengthen the overall credibility of the findings and allow us to identify additional variants. Across our phenotypes, loci regulating expression in central nervous system and adrenal or pancreas tissues are strongly enriched for association.

To identify genetic variants associated with serum BDNF, we tested the Val66Met (rs6265) functional variant and conducted a genome-wide association scan (GWAS). Methods. In a community-based sample (N = 2054; aged 19-101, M = 51, SD = 15) from Sardinia, Italy, we measured serum BDNF concentration and conducted a GWAS. Results. We estimated the heritability of serum BDNF to be 0.48 from sib-pairs. There was no association between serum BDNF and Val66Met in the SardiNIA sample and in a meta-analysis of published studies (k = 13 studies, total n = 4727, P = 0.92). Although no genome-wide significant associations were identified, some evidence of association was found in the BDNF gene (rs11030102, P = 0.001) and at two loci (rs7170215, P = 4.8 × 10(-5) and rs11073742 P = 1.2 × 10(-5)) near and within NTRK3 gene, a neurotrophic tyrosine kinase receptor. Conclusions. Our study and meta-analysis of the literature indicate that the BDNF Val66Met variant is not associated with serum BDNF, but other variants in the BDNF and NTRK3 genes might regulate the level of serum BDNF.

Show moreBACKGROUND: Independent of temporal circumstances, some individuals have greater susceptibility to depressive affects, such as feelings of guilt, sadness, hopelessness, and loneliness. Identifying the genetic variants that contribute to these individual differences can point to biological pathways etiologically involved in psychiatric disorders. METHODS: Genome-wide association scans for the depression scale of the Revised NEO Personality Inventory in community-based samples from a genetically homogeneous area of Sardinia, Italy (n = 3972) and from the Baltimore Longitudinal Study of Aging in the United States (n = 839). RESULTS: Meta-analytic results for genotyped or imputed single nucleotide polymorphisms indicate that the strongest association signals for trait depression were found in RORA (rs12912233; p = 6 × 10⁻⁷·), a gene involved in circadian rhythm. A plausible biological association was also found with single nucleotide polymorphisms within GRM8 (rs17864092; p = 5 × 10⁻⁶), a metabotropic receptor for glutamate, a major excitatory neurotransmitter in the central nervous system. CONCLUSIONS: These findings suggest shared genetic basis underlying the continuum from personality traits to psychopathology.

Show moreBACKGROUND: High Neuroticism and low Conscientiousness are frequently implicated in health-risk behaviors, such as smoking and overeating, as well as health outcomes, including mortality. Their associations with physiological markers of morbidity and mortality, such as inflammation, are less well documented. The present research examines the association between the five major dimensions of personality and interleukin-6 (IL-6), a pro-inflammatory cytokine often elevated in patients with chronic morbidity and frailty. METHOD: A population-based sample (n=4923) from four towns in Sardinia, Italy, had their levels of IL-6 measured and completed a comprehensive personality questionnaire, the NEO-PI-R. Analyses controlled for factors known to have an effect on IL-6: age; sex; smoking; weight; aspirin use; disease burden. RESULTS: High Neuroticism and low Conscientiousness were both associated with higher levels of IL-6. The findings remained significant after controlling for the relevant covariates. Similar results were found for C-reactive protein, a related marker of chronic inflammation. Further, smoking and weight partially mediated the association between impulsivity-related traits and higher IL-6 levels. Finally, logistic regressions revealed that participants either in the top 10% of the distribution of Neuroticism or the bottom 10% of conscientiousness had an approximately 40% greater risk of exceeding clinically relevant thresholds of IL-6. CONCLUSIONS: Consistent with the literature on personality and self-reported health, individuals high on Neuroticism or low on Conscientiousness show elevated levels of this inflammatory cytokine. Identifying critical medical biomarkers associated with personality may help to elucidate the physiological mechanisms responsible for the observed connections between personality traits and physical health.

Show moreIntroduction Approximately 20 million new sexually transmitted infections (STIs) are diagnosed yearly in the United States costing the healthcare system an estimated $16 billion in direct medical expenses. The presence of other STIs increases the risk of HIV transmission. The Centers for Disease Control and Prevention (CDC) has long recommended routine HIV screening for individuals with a diagnosed STI. Unfortunately, HIV screening prevalence among STI diagnosed patients are still sub-optimal in many healthcare settings. Objective To determine the proportion of STI-diagnosed persons in the Medicaid population who are screened for HIV, examine correlates of HIV screening, and to suggest critical intervention points to increase HIV screening in this population. Methods A retrospective database analysis was conducted to examine the prevalence and correlates of HIV screening among participants. Participant eligibility was restricted to Medicaid enrollees in 29 states with a primary STI diagnosis (chlamydia, gonorrhea, and syphilis) or pelvic inflammatory disease claim in 2009. HIV-positive persons were excluded from the study. Frequencies and descriptive statistics were conducted to characterize the sample in general and by STI diagnosis. Univariate and multivariate logistic regression were performed to estimate unadjusted odds ratios and adjusted odds ratio respectively and the 95% confidence intervals. Multivariate logistic regression models that included the independent variables (race, STI diagnosis, and healthcare setting) and covariates (gender, residential status, age, and state) were analyzed to examine independent associations with HIV screening. Results About 43% of all STI-diagnosed study participants were screened for HIV. STI-diagnosed persons that were between 20-24 years, female, residing in a large metropolitan area and with a syphilis diagnosis were more likely to be screened for HIV. Participants who received their STI diagnosis in the emergency department were less likely to be screened for HIV than those diagnosed in a physician's office. Conclusion This study showed that HIV screening prevalence among persons diagnosed with an STI are lower than expected based on the CDC's recommendations. These suboptimal HIV screening prevalence present "missed opportunities" for HIV screening in at-risk populations. Measures and incentives to increase HIV screening among all STI-diagnosed persons are vital to the timely identification of HIV infection, linkage to HIV care, and mitigating further HIV transmission.

Show moreBackground: In an era when obesity prevalence is high throughout much of the world, there is a correspondingly pervasive and strong culture of weight stigma. For example, representative studies show that some forms of weight discrimination are more prevalent even than discrimination based on race or ethnicity. Discussion: In this Opinion article, we review compelling evidence that weight stigma is harmful to health, over and above objective body mass index. Weight stigma is prospectively related to heightened mortality and other chronic diseases and conditions. Most ironically, it actually begets heightened risk of obesity through multiple obesogenic pathways. Weight stigma is particularly prevalent and detrimental in healthcare settings, with documented high levels of 'anti-fat' bias in healthcare providers, patients with obesity receiving poorer care and having worse outcomes, and medical students with obesity reporting high levels of alcohol and substance use to cope with internalized weight stigma. In terms of solutions, the most effective and ethical approaches should be aimed at changing the behaviors and attitudes of those who stigmatize, rather than towards the targets of weight stigma. Medical training must address weight bias, training healthcare professionals about how it is perpetuated and on its potentially harmful effects on their patients. Conclusion: Weight stigma is likely to drive weight gain and poor health and thus should be eradicated. This effort can begin by training compassionate and knowledgeable healthcare providers who will deliver better care and ultimately lessen the negative effects of weight stigma.

Show moreThe Uniform Determination of Death Act (UDDA) states that an individual is dead when "all functions of the entire brain" have ceased irreversibly. However, it has been questioned whether some functions of the hypothalamus, particularly osmoregulation, can continue after the clinical diagnosis of brain death (BD). In order to learn whether parts of the hypothalamus can continue to function after the diagnosis of BD, we performed 2 separate systematic searches of the MEDLINE database, corresponding to the functions of the posterior and anterior pituitary. No meta-analysis is possible due to nonuniformity in the clinical literature. However, some modest generalizations can reasonably be drawn from a narrative review and from anatomic considerations that explain why these findings should be expected. We found evidence suggesting the preservation of hypothalamic function, including secretion of hypophysiotropic hormones, responsiveness to anterior pituitary stimulation, and osmoregulation, in a substantial proportion of patients declared dead by neurological criteria. We discuss several possible explanations for these findings. We conclude by suggesting that additional clinical research with strict inclusion criteria is necessary and further that a more nuanced and forthright public dialogue is needed, particularly since standard diagnostic practices and the UDDA may not be entirely in accord.

Show moreA chronically elevated white blood cell (WBC) count is a risk factor for morbidity and mortality. The present research tests whether facets of impulsivity-impulsiveness, excitement-seeking, self-discipline, and deliberation-are associated with chronically elevated WBC counts. Community-dwelling participants (N = 5,652) from Sardinia, Italy, completed a standard personality questionnaire and provided blood samples concurrently and again 3 years later. Higher scores on impulsivity, in particular impulsiveness and excitement-seeking, were related to higher total WBC counts and higher lymphocyte counts at both time points. Impulsiveness was a predictor of chronic inflammation: for every standard deviation difference in this trait, there was an almost 25% higher risk of elevated WBC counts at both time points (OR = 1.23, 95% CI = 1.10-1.38). These associations were mediated, in part, by smoking and body mass index. The findings demonstrate that links between psychological processes and immunity are not limited to acute stressors; stable personality dispositions are associated with a chronic inflammatory state.

Show moreBackground Cardiovascular disease (CVD) is a leading health threat for HIV+ patients on antiretroviral therapy (ART); cardiometabolic comorbidities are key predictors of risk. Data are limited on incidence of metabolic comorbidities in HIV+ individuals initiating ART in low and middle income countries (LMICs), particularly for Hispanics. We examined incidence of diabetes and obesity in a prospective cohort of those initiating ART in the Dominican Republic. Methods Participants >= 18 years, initiating ART <90 days prior to study enrollment, were examined for incidence of impaired fasting glucose (IFG), diabetes mellitus (DM), overweight, and obesity. Fasting plasma glucose (FPG) 100-125mg/dl defined IFG; FPG >= 126 mg/dl, diagnosis per medical record, or use of hypoglycemic medication defined DM. Overweight and obesity were BMI 25-30 and >= 30kg/m2, respectively. Dyslipidemia was total cholesterol >= 240mg/dl or use of lipid-lowering medication. Framingham risk equation was used to determine ten-year CVD risk at the end of observation. Results Of 153 initiating ART, 8 (6%) had DM and 23 (16%) had IFG at baseline, 6 developed DM (28/1000 person-years follow up [PYFU]) and 46 developed IFG (329/1000 PYFU). At baseline, 24 (18%) were obese and 36 (27%) were overweight, 15 became obese (69/1000 PYFU) and 22 became overweight (163/1000 PYFU). Median observation periods for the diabetes and obesity analyses were 23.5 months and 24.3 months, respectively. Increased CVD risk (>= 10% 10-year Framingham risk score) was present for 13% of the cohort; 79% of the cohort had >= 1 cardiometabolic comorbidity, 48% had >= 2, and 13% had all three. Conclusions In this Hispanic cohort in an LMIC, incidences of IFG/DM and overweight/obesity were similar to or higher than that found in high income countries, and cardiometabolic disorders affected three-quarters of those initiating ART. Care models incorporating cardiovascular risk reduction into HIV treatment programs are needed to prevent CVD-associated mortality in this vulnerable population.

Show moreBackground: Approximately 24 million Americans are living with diabetes. Patient activation among individuals with diabetes is critical to successful diabetes management. The Patient Centered Medical Home (PCMH) model holds promise for increasing patient activation in managing their health. However, what is not well understood is the extent to which individual components of the PCMH model, such as the quality of physician-patient interactions and organizational features of care, contribute to patient activation. This study's objective is to determine the relative importance of the PCMH constructs or domains to patient activation among individuals living with diabetes. Methods: This study is a cross-sectional analysis of 1253 primary care patients surveyed with type II diabetes. The dependent variable, patient activation, was assessed using the Patient Activation Measure (PAM). Independent variables included 7 PCMH domains-organizational access, integration of care, comprehensive knowledge, office staff helpfulness, communication, interpersonal treatment and trust. Ordered logistic regression was performed to determine whether each PCMH domain was independently associated with patient activation, followed by a final ordered logistic regression that included all the PCMH domains in a single adjusted model. Results: Using the full adjusted model, the odds of patients reporting higher activation scores (PAM) were found to be significant in the domains that represented organizational access (OR 1.56, 95% CI 1.31-1.85) and comprehensive knowledge (OR 1.44, 95% CI 1.13-1.85). Conclusions: Many practices have struggled with the challenge to develop fully functional patient-centered medical homes. In an effort to become more patient-centered, this study aimed to address what factors activated diabetic patients to adhere to diabetes management plan. Understanding these factors can help identify PCMH attributes that practices can prioritize and improve upon to assist their patients in improving health outcomes.

Weighted logistic regression models were used to determine the association between marijuana use (past 12 months) and durable viral suppression (HIV-1 RNA value of ≤ 200 copies/milliliter in all measurements within the past 12 months). Of the 1,902 PLWH receiving antiretroviral therapy, completed an interview, and had a linked MRA, 20% reported marijuana use (13% less than daily and 7% daily use) and 73% achieved durable viral suppression. In multivariable analysis, marijuana use was not significantly associated with durable viral suppression in daily [Adjusted Odds Ratio (AOR): 0.87, 95% confidence interval (CI): 0.58, 1.33] or in less than daily [AOR: 0.83, 95% CI: 0.51, 1.37] users as compared to non-users when adjusting for sociodemographic factors, time since HIV diagnosis, depressive symptoms, alcohol, cigarette and other substance use. In this sample of PLWH receiving medical care in Florida, there was no statistically significant association between marijuana use and viral suppression. However, as the limits of the confidence intervals include effects that may be considered to be clinically important, there is a need for additional evidence from other samples and settings that include more marijuana users.

Abstract/Description: Birth defects are responsible for a large proportion of disability and infant mortality. Exposure to a variety of pesticides have been linked to increased risk of birth defects. We conducted a case-control study to estimate the associations between a residence-based metric of agricultural pesticide exposure and birth defects.

Show moreBirth defects are responsible for a large proportion of disability and infant mortality. Exposure to a variety of pesticides have been linked to increased risk of birth defects. We conducted a case-control study to estimate the associations between a residence-based metric of agricultural pesticide exposure and birth defects. We linked singleton live birth records for 2003 to 2005 from the North Carolina (NC) State Center for Health Statistics to data from the NC Birth Defects Monitoring Program. Included women had residence at delivery inside NC and infants with gestational ages from 20 to 44 weeks (n = 304,906). Pesticide exposure was assigned using a previously constructed metric, estimating total chemical exposure (pounds of active ingredient) based on crops within 500 meters of maternal residence, specific dates of pregnancy, and chemical application dates based on the planting/harvesting dates of each crop. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals for four categories of exposure (<10(th) , 10-50(th) , 50-90(th) , and >90(th) percentiles) compared with unexposed. Models were adjusted for maternal race, age at delivery, education, marital status, and smoking status. We observed elevated ORs for congenital heart defects and certain structural defects affecting the gastrointestinal, genitourinary and musculoskeletal systems (e.g., OR [95% confidence interval] [highest exposure vs. unexposed] for tracheal esophageal fistula/esophageal atresia = 1.98 [0.69, 5.66], and OR for atrial septal defects: 1.70 [1.34, 2.14]). Our results provide some evidence of associations between residential exposure to agricultural pesticides and several birth defects phenotypes.

Show moreBackground: This article summarizes exploratory analyses of relationships between chronic inflammation, its physical consequences, and quality of life (QoL). It summarizes key findings from preliminary analyses, and contextualizes these results with extant sociomedical literature to recommend directions for future research. Methods: Cross-sectional data from the National Social Life, Health, and Aging Project (NSHAP) were used to explore these relationships. Inflammation was assessed via the biomarker C-reactive protein (CRP). We examined associations between CRP levels and two different domains of QoL: happiness with life in general and happiness with intimate relationships. We used ordinal logistic regression with companion OLS models and Sobel-Goodman tests to assess potential mediation, and also conducted a variety of sensitivity analyses. Results: Findings suggest that mediation pathways for the overall association between chronic inflammation and QoL may differ markedly across particular outcome constructs. Specifically, it shows mediation potential for the clinical sequelae of chronic inflammation in frameworks using happiness as an outcome measure, but not in those using relationship satisfaction. Disability appears to mediate the effect of inflammation by 27 %; chronic pain appears to exert a similar mediation effect of 21 %. Conclusions: Pain and disability linked to chronic inflammation appear to play a small but significant mediating role in the overall reduction in QoL observed among older adults with biomarker evidence of chronic inflammation. We note that these patterns are best framed as dynamic elements of a complex causal fabric, rather than powerful determinants that override other factors contributing to QoL. Hypotheses for further exploration using longitudinal data from the NSHAP are thus offered, pending availability of Wave III data in future years.

Abstract/Description: Extraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report on a large meta-analysis of GWA studies for extraversion in 63,030 subjects in 29 cohorts. Extraversion item data from multiple personality...
Show moreExtraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report on a large meta-analysis of GWA studies for extraversion in 63,030 subjects in 29 cohorts. Extraversion item data from multiple personality inventories were harmonized across inventories and cohorts. No genome-wide significant associations were found at the single nucleotide polymorphism (SNP) level but there was one significant hit at the gene level for a long non-coding RNA site (LOC101928162). Genome-wide complex trait analysis in two large cohorts showed that the additive variance explained by common SNPs was not significantly different from zero, but polygenic risk scores, weighted using linkage information, significantly predicted extraversion scores in an independent cohort. These results show that extraversion is a highly polygenic personality trait, with an architecture possibly different from other complex human traits, including other personality traits. Future studies are required to further determine which genetic variants, by what modes of gene action, constitute the heritable nature of extraversion.

This trait is a central feature of extraversion and is a component of the multifaceted impulsivity construct. Those who score high on measures of excitement-seeking are more likely to smoke, use other drugs, gamble, drive recklessly, have unsafe/unprotected sex and engage in other risky behaviors of clinical and social relevance.

Show moreThe tendency to seek stimulating activities and intense sensations define excitement-seeking, a personality trait akin to some aspects of sensation-seeking. This trait is a central feature of extraversion and is a component of the multifaceted impulsivity construct. Those who score high on measures of excitement-seeking are more likely to smoke, use other drugs, gamble, drive recklessly, have unsafe/unprotected sex and engage in other risky behaviors of clinical and social relevance. To identify common genetic variants associated with the Excitement-Seeking scale of the Revised NEO Personality Inventory, we performed genome-wide association studies in six samples of European ancestry (N=7860), and combined the results in a meta-analysis. We identified a genome-wide significant association between the Excitement-Seeking scale and rs7600563 (P=2 × 10(-8)). This single-nucleotide polymorphism maps within the catenin cadherin-associated protein, alpha 2 (CTNNA2) gene, which encodes for a brain-expressed α-catenin critical for synaptic contact. The effect of rs7600563 was in the same direction in all six samples, but did not replicate in additional samples (N=5105). The results provide insight into the genetics of excitement-seeking and risk-taking, and are relevant to hyperactivity, substance use, antisocial and bipolar disorders.

Title: The Nature and Implementation of Representation in Biological Systems.
Creator: Nair-Collins, Michael
Abstract/Description: I defend a theory of mental representation that satisfies naturalistic constraints. Briefly, we begin by distinguishing (i) what makes something a representation from (ii) given that a thing is a representation, what determines what it represents. Representations are states of biological organisms, so we should expect a unified theoretical framework for explaining both what it is to be a representation as well as what it is to be a heart or a kidney.

Show moreI defend a theory of mental representation that satisfies naturalistic constraints. Briefly, we begin by distinguishing (i) what makes something a representation from (ii) given that a thing is a representation, what determines what it represents. Representations are states of biological organisms, so we should expect a unified theoretical framework for explaining both what it is to be a representation as well as what it is to be a heart or a kidney. I follow Millikan in explaining (i) in terms of teleofunction, explicated in terms of natural selection. To explain (ii), we begin by recognizing that representational states do not have content, that is, they are neither true nor false except insofar as they both "point to" or "refer" to something, as well as "say" something regarding whatever it is they are about. To distinguish veridical from false representations, there must be a way for these separate aspects to come apart; hence, we explain (ii) by providing independent theories of what I call f-reference and f-predication (the 'f' simply connotes 'fundamental', to distinguish these things from their natural language counterparts). Causal theories of representation typically founder on error, or on what Fodor has called the disjunction problem. Resemblance or isomorphism theories typically founder on what I've called the non-uniqueness problem, which is that isomorphisms and resemblance are practically unconstrained and so representational content cannot be uniquely determined. These traditional problems provide the motivation for my theory, the structural preservation theory, as follows. F-reference, like reference, is a specific, asymmetric relation, as is causation. F-predication, like predication, is a non-specific relation, as predicates typically apply to many things, just as many relational systems can be isomorphic to any given relational system. Putting these observations together, a promising strategy is to explain f-reference via causal history and f-predication via something like isomorphism between relational systems. This dissertation should be conceptualized as having three parts. After motivating and characterizing the problem in chapter 1, the first part is the negative project, where I review and critique Dretske's, Fodor's, and Millikan's theories in chapters 2-4. Second, I construct my theory about the nature of representation in chapter 5 and defend it from objections in chapter 6. In chapters 7-8, which constitute the third and final part, I address the question of how representation is implemented in biological systems. In chapter 7 I argue that single-cell intracortical recordings taken from awake Macaque monkeys performing a cognitive task provide empirical evidence for structural preservation theory, and in chapter 8 I use the empirical results to illustrate, clarify, and refine the theory.

Show moreNeighborhoods can provide opportunities for children to maintain a healthy weight or encourage unhealthy weight gain. Which neighborhood characteristics matter most remains poorly understood. We investigated links between neighborhood characteristics and weight change over the summer in children from 12 elementary schools with a high proportion of children from low-income families, in a mid-sized city in the US South. Mixed models and objective measures of height and weight were used. Study participants were 2770 children (average age 8.3, range 5.6-12.6 years). Older and female children and those who were already overweight were more likely to gain weight over the summer compared to younger, male, and normal weight children. Overweight children who lived near 2 or more small grocery stores gained less weight than overweight children who lived near 0 (weight change, p = 0.0468; body mass index (BMI) change, p = 0.0209) or 1 store (weight change, p = 0.0136; BMI change, p = 0.0033). Normal weight children living in neighborhoods with more large multifamily buildings gained more weight over the summer, although this association only approached significance. Additional efforts to understand which neighborhood factors have greater significance for overweight compared to normal weight children are warranted.
