Title: Examination of Nicotine-Induced Alterations in Germ Cell DNA.
Creator: Lopez, Katheryn, Medicine, Biomedical Sciences
Abstract/Description: While evidence from mouse models strongly suggests that prenatal nicotine exposure supports a hyperactive-inattentive phenotype following direct exposure in utero via maternal circulation (Zhu et al 2014), there is little evidence that suggests consequences resulting from indirect exposure of the offspring through a father's use of tobacco products. In order to address the question of the influence of a father smoking on their offspring, we developed a paternal nicotine exposure mouse model...
Show moreWhile evidence from mouse models strongly suggests that prenatal nicotine exposure supports a hyperactive-inattentive phenotype following direct exposure in utero via maternal circulation (Zhu et al 2014), there is little evidence that suggests consequences resulting from indirect exposure of the offspring through a father's use of tobacco products. In order to address the question of the influence of a father smoking on their offspring, we developed a paternal nicotine exposure mouse model in which adult male mice were exposed to nicotine in their drinking water for 12 consecutive weeks.We found that the offspring of these nicotine exposed male mice displayed deficits in working memory and attention, behavioral phenotypes that have been previously linked to ADHD. These intriguing findings were rationale to hypothesize that the fathers' germ cells may have undergone genetic changes as a result of the nicotine exposure and that these changes in the germ cell DNA were the basis for transmission of an ADHD-like phenotype to the offspring.To address these possibilities, we are performing molecular genetic analysis of germ cells and examining gross morphology of the testes of nicotine-exposed fathers to elucidate mechanisms by which paternal nicotine exposure may cause behavioral changes associated with ADHD in the offspring

Title: Hypothalamic-Pituitary Function in Brain Death: A Review.
Creator: Nair-Collins, Michael, Northrup, Jesse, Olcese, James
Abstract/Description: The 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,...
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.

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.

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.

Show moreBACKGROUND AND OBJECTIVES: Retention and recruitment of minority faculty members continues to be a concern of medical schools because there is higher attrition and talent loss among this group. While much has been written, there has not been a systematic review published on this topic. This is the first study to use evidence-based medicine (EBM) criteria and apply it to this issue. METHODS: We searched MEDLINE, Web of Knowledge, ProQuest, and Google Scholar for papers relating to the recruitment and retention of minority faculty. We then graded the evidence using the EBM criteria as defined by the American Academy of Family Physicians. The same criteria were applied to extract evidence-based observations of problems in recruitment and retention for minority faculty. RESULTS: Of the 548 studies identified and reviewed, 11 met inclusion criteria for this literature review. This article presents the data from the reviewed papers that described or evaluated minority faculty development programs. Faculty development programs in 15 different institutions showed mentoring and faculty development for minority faculty could increase retention, academic productivity, and promotion rates for this group. ConclusionS: For medical schools to be successful in retention and recruitment of minority medical school faculty, specific programs need to be in place. Overall evidence is strong that faculty development programs and mentoring programs increase retention, productivity, and promotion for this group of medical faculty. This paper is a call to action for more faculty development and mentorship programs to reduce the disparities that exist between minority faculty and all other faculty members.

Show moreWith the number of individuals diagnosed with type 2 diabetes on the rise, it has become more important to ensure these patients are effectively treated. The Centers for Disease Control and Prevention estimated that 8.3% of all Americans were diagnosed with diabetes in 2011 and this number will likely continue to rise. With lifestyle interventions, such as proper diet and exercise, continuing to be an essential component of diabetes treatment, more patients are requiring medication therapy to help them reach their therapeutic goals. It is important for the clinician, when determining the treatment strategy for these individuals, to find a balance between reaching treatment goals and limiting the adverse effects of the treatments themselves. Of all the adverse events associated with treatment of diabetes, the risk of hypoglycemia is one that most therapies have in common. This risk is often a limiting factor when attempting to aggressively treat diabetic patients. This manuscript will review how hypoglycemia is defined and categorized, as well as discuss the prevalence of hypoglycemia among the many different treatment options.

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.

Show moreMitochondria, important energy centers in the cell, also control sperm cell morphogenesis.Drosophila spermatids have a remarkably large mitochondrial formation called the nebenkern. Immediately following meiosis during sperm development, the mitochondria in the spermatid fuse together into two large aggregates which then wrap around one another to produce the spherical nebenkern: a giant mitochondrion about 6 micrometers in diameter. The fused mitochondria play an important role in sperm tail elongation by providing a structural platform to support the elongation of sperm cells. We have identified a novel testis-specific protein, Spermitin (Sprn), a protein with a Pleckstrin homology-like (PH) domain related to Ran-binding protein 1 at its C-terminus. Fluorescence microscopy showed that Sprn localizes at mitochondria in transfected Kc167 cells, and in the nebenkern throughout spermatid morphogenesis. The role of Sprn is unclear, as sprn mutant males are fertile, and have sperm tail length comparable to the wild-type.

After successful integration with the curriculum, a Course Page is now available for every required course in UGME at Florida State University. The 2005 Course Pages emphasized a variety of relevant course resources; the 2013 standardized design emphasizes usability and relies on faculty approval of all course resources. In 2010, Course Pages became accessible from any page on the medical library's website. Course Pages have enhanced the speed and accessibility to medical library resources for medical students and faculty from both on and off campus, and they have led to improved evaluation of usage, cost savings, more focused negotiations, and justified purchases.

Show moreObjectives Our library has provided 24/7 access for student study space since 2010. This service has functioned as anticipated with minor policy breaches in 2010 and 2013. The purpose of this study was to determine how well 24/7 access to our library is working, obtain student feedback on security procedures, and solicit ideas from all stakeholders for future improvements. Methods Stakeholders for 24/7 access to our academic health sciences library include both the service providers (library, student affairs, and security/legal personnel) and the service users (first- and second-year medical students and biomedical graduate students). To evaluate the effectiveness of the library's 24/7 access service, the authors conducted a series of free-response interviews with several service provider and user stakeholders to solicit the most detailed feedback possible. The authors also administered a brief survey to determine if students were satisfied with unstaffed access to library study space. The results of stakeholder feedback were used to evaluate the value of our extensive planning for 24/7 access to the library, our thorough and consistent implementation, and our responsiveness to the needs of our students. Results: Our library director invited (via email) 14 student/staff stakeholders to be interviewed by the primary investigator (PI) and co-PI. Three students and three staff members agreed to be interviewed; five interviews were conducted face-to-face and one was conducted by phone. In addition, our library director sent an email invitation to complete a 10-question survey to approximately 500 students; 114 surveys were completed. From the interviews and the survey, shared themes as well as several unique feedback items emerged. In general, the overwhelming response was that the 24/7 service meets the needs of students, providing a secure, consistent study area for students who do not choose to study in another College of Medicine study space, in another campus library, at home, or at another location. Specifically, 90% of the students were not concerned about safety/security issues in the library during unstaffed hours, 82% indicated that the library environment was conducive to studying during unstaffed hours, and 83% felt that the library's orientation on 24/7 policies and procedures has met their needs. Conclusions: Collecting formal feedback on our 24/7 service has validated the time spent in planning, implementation, and responding to student needs, and has also elicited several ideas for improving the 24/7 service. We plan to continue interviewing and surveying 24/7 stakeholders on a yearly basis to solicit current feedback and continually improve the service.

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.

Show moreBackground. Limited information is available on whether the associations of microalbuminuria and macroalbuminuria with the odds of hypertension differ among non-Hispanic Whites, non-Hispanic Blacks, and Hispanics. Methods. Cross-sectional data of 24,949 participants aged ≥18 years were collected from the National Health and Nutrition Examination Survey (NHANES) 1999–2008. Odds ratios of hypertension for microalbuminuria and macroalbuminuria were estimated by conducting weighted multiple logistic regression models. Results. After adjustment for extensive confounding factors, microalbuminuria is 1.45 (95% confidence interval (CI) [1.17, 1.80]), 2.07 (95% CI [1.52, 2.83]) and 2.81 (95% CI [2.06, 3.84]) times more likely to be associated with hypertension, and macroalbuminuria is 4.08 (95% CI [1.98, 8.38]), 8.62 (95% CI [3.84, 19.35]), and 4.43 (95% CI [2.13, 9.21]) times in non-Hispanic Whites, non-Hispanic Blacks, and Hispanics, respectively. The odds of hypertension for microalbuminuria (versus normalbuminuria) were 52% higher in non-Hispanic Blacks and 98% higher in Hispanics than in non-Hispanic Whites; the odds of hypertension for macroalbuminuria (versus normalbuminuria) did not differ among racial groups. Conclusion. Racial differences in the relation between microalbuminuria and hypertension are prevalent among non-Hispanic Whites, non-Hispanic Blacks, and Hispanics. More screening efforts should be encouraged in normotensive non-Hispanic Blacks and Hispanics with microalbuminuria.

Show moreEconomic variables such as income, education, and occupation are known to affect mortality and morbidity, such as cardiovascular disease, and have also been shown to be partly heritable. However, very little is known about which genes influence economic variables, although these genes may have both a direct and an indirect effect on health. We report results from the first large-scale collaboration that studies the molecular genetic architecture of an economic variable–entrepreneurship–that was operationalized using self-employment, a widely-available proxy. Our results suggest that common SNPs when considered jointly explain about half of the narrow-sense heritability of self-employment estimated in twin data (σg2/σP2 = 25%, h2 = 55%). However, a meta-analysis of genome-wide association studies across sixteen studies comprising 50,627 participants did not identify genome-wide significant SNPs. 58 SNPs with p<10−5 were tested in a replication sample (n = 3,271), but none replicated. Furthermore, a gene-based test shows that none of the genes that were previously suggested in the literature to influence entrepreneurship reveal significant associations. Finally, SNP-based genetic scores that use results from the meta-analysis capture less than 0.2% of the variance in self-employment in an independent sample (p≥0.039). Our results are consistent with a highly polygenic molecular genetic architecture of self-employment, with many genetic variants of small effect. Although self-employment is a multi-faceted, heavily environmentally influenced, and biologically distal trait, our results are similar to those for other genetically complex and biologically more proximate outcomes, such as height, intelligence, personality, and several diseases.

Title: Myofilament Calcium De-Sensitization and Contractile Uncoupling Prevent Pause-Triggered Ventricular Tachycardia in Mouse Hearts with Chronic Myocardial Infarction.

Abstract/Description: Myocardial infarction (MI) is a major risk for ventricular arrhythmia. Pause-triggered ventricular arrhythmia can be caused by increased myofilament Ca binding due to sarcomeric mutations or Ca-sensitizing compounds. Myofilament Ca sensitivity is also increased after MI. Here we hypothesize that MI increases risk for pause-triggered ventricular arrhythmias, which can be prevented by myofilament Ca-desensitization and contractile uncoupling.

Myofilament Ca sensitivity is also increased after MI. Here we hypothesize that MI increases risk for pause-triggered ventricular arrhythmias, which can be prevented by myofilament Ca-desensitization and contractile uncoupling. To test this hypothesis, we generated a murine chronic MI model using male B6SJLF1/J mice (n=40) that underwent permanent ligation of the left anterior descending coronary artery. 4 weeks post MI, cardiac structure, function and myofilament Ca sensitivity were evaluated. Pause-dependent arrhythmia susceptibility was quantified in isolated hearts with pacing trains of increasing frequency, followed by a pause and an extra stimulus. Coronary ligation resulted in a mean infarct size of 39.6±5.7% LV and fractional shortening on echocardiography was reduced by 40% compared to non-infarcted controls. Myofilament Ca sensitivity was significantly increased in post MI hearts (pCa50: Control=5.66±0.03; MI=5.84±0.05; P

Title: Personality, Metabolic Rate and Aerobic Capacity.
Creator: Terracciano, Antonio, Schrack, Jennifer, Sutin, Angelina, Chan, Wayne, Simonsick, Eleanor M., Ferrucci, Luigi
Abstract/Description: Personality traits and cardiorespiratory fitness in older adults are reliable predictors of health and longevity. We examined the association between personality traits and energy expenditure at rest (basal metabolic rate) and during normal and maximal sustained walking. Personality traits and oxygen (VO(2)) consumption were assessed in 642 participants from the Baltimore Longitudinal Study of Aging.

Show morePersonality traits and cardiorespiratory fitness in older adults are reliable predictors of health and longevity. We examined the association between personality traits and energy expenditure at rest (basal metabolic rate) and during normal and maximal sustained walking. Personality traits and oxygen (VO(2)) consumption were assessed in 642 participants from the Baltimore Longitudinal Study of Aging. Results indicate that personality traits were mostly unrelated to resting metabolic rate and energy expenditure at normal walking pace. However, those who scored lower on neuroticism (r = -0.12) and higher on extraversion (r = 0.11), openness (r = 0.13), and conscientiousness (r = 0.09) had significantly higher energy expenditure at peak walking pace. In addition to greater aerobic capacity, individuals with a more resilient personality profile walked faster and were more efficient in that they required less energy per meter walked. The associations between personality and energy expenditure were not moderated by age or sex, but were in part explained by the proportion of fat mass. In conclusion, differences in personality may matter the most during more challenging activities that require cardiorespiratory fitness. These findings suggest potential pathways that link personality to health outcomes, such as obesity and longevity.

Title: The Effect of Birth Cohort on Well-Being: The Legacy of Economic Hard Times.

Abstract/Description: In the present research, we examined the effects of age, cohort, and time of measurement on well-being across adulthood. 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.

Show moreIn the present research, we examined the effects of age, cohort, and time of measurement on well-being across adulthood. 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.

Show moreWeight discrimination is prevalent in American society. Although associated consistently with psychological and economic outcomes, less is known about whether weight discrimination is associated with longitudinal changes in obesity. The objectives of this research are (1) to test whether weight discrimination is associated with risk of becoming obese (Body Mass Index≥30; BMI) by follow-up among those not obese at baseline, and (2) to test whether weight discrimination is associated with risk of remaining obese at follow-up among those already obese at baseline. Participants were drawn from the Health and Retirement Study, a nationally representative longitudinal survey of community-dwelling US residents. A total of 6,157 participants (58.6% female) completed the discrimination measure and had weight and height available from the 2006 and 2010 assessments. Participants who experienced weight discrimination were approximately 2.5 times more likely to become obese by follow-up (OR = 2.54, 95% CI = 1.58–4.08) and participants who were obese at baseline were three times more likely to remain obese at follow up (OR = 3.20, 95% CI = 2.06–4.97) than those who had not experienced such discrimination. These effects held when controlling for demographic factors (age, sex, ethnicity, education) and when baseline BMI was included as a covariate. These effects were also specific to weight discrimination; other forms of discrimination (e.g., sex, race) were unrelated to risk of obesity at follow-up. The present research demonstrates that, in addition to poorer mental health outcomes, weight discrimination has implications for obesity. Rather than motivating individuals to lose weight, weight discrimination increases risk for obesity.

Show moreAbstract The 15 human kallikrein-related peptidases (KLKs) are clinically important biomarkers and therapeutic targets of interest in inflammation, cancer, and neurodegenerative disease. KLKs are secreted as inactive pro-forms (pro-KLKs) that are activated extracellularly by specific proteolytic release of their amino-terminal pro-peptide, and this is a key step in their functional regulation. Physiologically relevant KLK regulatory cascades of activation have been described in skin desquamation and semen liquefaction, and work by a large number of investigators has elucidated pairwise and autolytic activation relationships among the KLKs with the potential for more extensive activation cascades. More recent work has asked whether functional intersection of KLKs with other types of regulatory proteases exists. Such studies show a capacity for members of the thrombostasis axis to act as broad activators of pro-KLKs. In the present report, we ask whether such functional intersection is possible between the KLKs and the members of the matrix metalloproteinase (MMP) family by evaluating the ability of the MMPs to activate pro-KLKs. The results identify MMP-20 as a broad activator of pro-KLKs, suggesting the potential for intersection of the KLK and MMP axes under pathological dysregulation of MMP-20 expression.

Abstract/Description: Three troponin T (TnT) mutants that cause hypertrophic, restrictive, and dilated cardiomyopathy (I79N, ΔE96, and ΔK210, respectively), were examined using the thin-filament extraction/reconstitution technique. Effects of Ca(2+), ATP, phosphate, and ADP concentrations on force and its transients were studied at 25°C. Maximal Ca(2+) tension (THC) and Ca(2+)-activatable tension (Tact), respectively, were similar among I79N, ΔE96, and WT, whereas ΔK210 led to a significantly lower THC (∼20% less)...

Effects of Ca(2+), ATP, phosphate, and ADP concentrations on force and its transients were studied at 25°C. Maximal Ca(2+) tension (THC) and Ca(2+)-activatable tension (Tact), respectively, were similar among I79N, ΔE96, and WT, whereas ΔK210 led to a significantly lower THC (∼20% less) and Tact (∼25% less) than did WT. In pCa solution containing 8 mM Pi and ionic strength adjusted to 200 mM, the Ca(2+) sensitivity (pCa50) of I79N (5.63 ± 0.02) and ΔE96 (5.60 ± 0.03) was significantly greater than that of WT (5.45 ± 0.04), but the pCa50 of ΔK210 (5.54 ± 0.04) remained similar to that of WT. Five equilibrium constants were deduced using sinusoidal analysis. All three mutants showed significantly lower K0 (ADP association constant) and larger K4 (equilibrium constant of force generation step) relative to the corresponding values for WT. I79N and ΔK210 were associated with a K2 (equilibrium constant of cross-bridge detachment step) significantly lower than that of ΔE96 and WT. These results demonstrated that at pCa 4.66, the force/cross-bridge is ∼18% less in I79N and ∼41% less in ΔK210 than that in WT. These results indicate that the molecular pathogenesis of the cardiac TnT mutation-related cardiomyopathies is different for each mutation.

A linear polygenic score from all measured SNPs accounts for ≈2% of the variance in both educational attainment and cognitive function. Genes in the region of the loci have previously been associated with health, cognitive, and central nervous system phenotypes, and bioinformatics analyses suggest the involvement of the anterior caudate nucleus. These findings provide promising candidate SNPs for follow-up work, and our effect size estimates can anchor power analyses in social-science genetics.

Because such research projects typically involve formulating various search strategies, searching several library databases in-depth, and collecting, managing and sharing citations, the MML DALR program uses a team approach to meet researchers' needs. With a team approach, the time and skills of librarians, researchers in the College of Medicine's academic departments, and associates for library research embedded within each department complement each other efficiently and effectively. The poster describes how the research team concept evolved, and features examples of the project documentation, such as the participation requirements for the departmental associates for library research (DALRs).

Show moreCaregivers of older adults with dementia face significant challenges associated with their care recipients' condition and with their own mental and physical well-being. Qualitative research data were collected via interviews with caregivers who participated in the African-American Alzheimer's Caregiver Training and Support (ACTS) research project. Analysis of these data with a focus on information use indicated that participating caregivers' information use environments were shaped by key individuals, settings, and information sources. These included the ACTS counselors, ACTS intervention guidebook, fellow caregivers, use of a personal calendar/datebook, and the identification of key problems and development of goals to help ameliorate those problems. CBT groups fostered sharing, synthesizing, and validating information about dementia caregiving and dementia care resources; the ACTS CBT guidebook served as an important physical touchstone of reliable and portable information. Understanding the specific needs, behaviors, and constraints of African-American caregivers is important to the future development of information components of tailored, depression-reduction interventions.

Show moreKallikrein-related peptidase 6 (KLK6) is a trypsin-like serine protease upregulated at sites of central nervous system (CNS) injury, including de novo expression by reactive astrocytes, yet its physiological actions are largely undefined. Taken with recent evidence that KLK6 activates G-protein-coupled protease-activated receptors (PARs), we hypothesized that injury-induced elevations in KLK6 contribute to the development of astrogliosis and that this occurs in a PAR-dependent fashion. Using primary murine astrocytes and the Neu7 astrocyte cell line, we show that KLK6 causes astrocytes to transform from an epitheliod to a stellate morphology and to secrete interleukin 6 (IL-6). By contrast, KLK6 reduced expression of glial fibrillary acidic protein (GFAP). The stellation-promoting activities of KLK6 were shown to be dependent on activation of the thrombin receptor, PAR1, as a PAR1-specific inhibitor, SCH79797, blocked KLK6-induced morphological changes. The ability of KLK6 to promote astrocyte stellation was also shown to be linked to activation of protein kinase C (PKC). These studies indicate that KLK6 is positioned to serve as a molecular trigger of select physiological processes involved in the development of astrogliosis and that this is likely to occur at least in part by activation of the G-protein-coupled receptor, PAR1.

Creator: Davis, Laura, Provost, Bridgette, Rodríguez, Jose
Abstract/Description: Compared with hysterectomy or myomectomy, UAE for treating fibroids results in similar patient satisfaction. UAE is associated with fewer blood transfusions, shorter hospital stays, and quicker resumption of normal activities than surgical treatment. However, patients undergoing UAE are more likely to require further intervention at 2 and 5 years and are more likely to have minor complications than patients treated surgically (SOR: A, systematic review of RCTs).

Show moreHuman Biological Materials (HBM) come from individuals in a variety of circumstances. The use of HBM for research purposes raises a host of difficult ethical questions. The law is important in this arena because, in most cases, legal principles significantly influence the making of ethical choices. Following a general overview of research regulation in the United States generally and a few comments on the relevance of international statements for this country, this article explores several specific legal issues, and their ethical implications, related to the obtaining and handling of HBM for research purposes, namely: informed consent; privacy; and commercial or ownership (property) interests in HBM. The article concludes that, although the realistic liability risks are low, the law's important role in characterizing the rights and responsibilities involved will be very influential in shaping the ways that the chasm between science and ethics is resolved within the context of the use of human tissue for research purposes.

Abstract/Description: BACKGROUND: Physical inactivity plays a central role in the age-related decline in muscle strength, an important component in the process leading to disability. Personality, a significant determinant of health behaviors including physical activity, could therefore impact muscle strength throughout adulthood and affect the rate of muscle strength decline with aging.

Show moreBACKGROUND: Physical inactivity plays a central role in the age-related decline in muscle strength, an important component in the process leading to disability. Personality, a significant determinant of health behaviors including physical activity, could therefore impact muscle strength throughout adulthood and affect the rate of muscle strength decline with aging. Personality typologies combining "high neuroticism" (N ≥ 55), "low extraversion" (E < 45), and "low conscientiousness" (C < 45) have been associated with multiple risky health behaviors but have not been investigated with regards to muscle strength. PURPOSE: The purpose of this study is to investigate associations between individual and combined typologies consisting of high N, low E, and low C and muscle strength, and whether physical activity and body mass index act as mediators. METHOD: This cross-sectional study includes 1,220 participants from the Baltimore Longitudinal Study of Aging. RESULTS: High N was found among 18%, low E among 31%, and low C among 26% of the sample. High levels of N, particularly when combined with either low E or low C, were associated with lower muscle strength compared with having only one or none of these personality types. Facet analyses suggest an important role for the N components of depression and hostility. Physical activity level appears to partly explain some of these associations. CONCLUSION: Findings provide support for the notion that the typological approach to personality may be useful in identifying specific personality types at risk of low muscle strength and offer the possibility for more targeted prevention and intervention programs.

Title: Associations Between Personality Traits, Physical Activity Level, and Muscle Strength.
Creator: Tolea, Magdalena, Terracciano, Antonio, Simonsick, Eleanor M., Metter, E. Jeffrey, Costa, Paul, Ferrucci, Luigi
Abstract/Description: Associations among personality as measured by the Five Factor Model, physical activity, and muscle strength were assessed using data from the Baltimore Longitudinal Study of Aging (N = 1220, age: mean = 58, SD = 16). General linear modeling with adjustment for age, sex, race, and body mass index, and bootstrapping for mediation were used. We found neuroticism and most of its facets to negatively correlate with strength. The extraversion domain and its facets of warmth, activity, and positive...
Show moreAssociations among personality as measured by the Five Factor Model, physical activity, and muscle strength were assessed using data from the Baltimore Longitudinal Study of Aging (N = 1220, age: mean = 58, SD = 16). General linear modeling with adjustment for age, sex, race, and body mass index, and bootstrapping for mediation were used. We found neuroticism and most of its facets to negatively correlate with strength. The extraversion domain and its facets of warmth, activity, and positive-emotions were positively correlated with strength, independent of covariates. Mediation analysis results suggest that these associations are partly explained by physical activity level. Findings extend the evidence of an association between personality and physical function to its strength component and indicate health behavior as an important pathway.

Abstract/Description: Personality can be thought of as a set of characteristics that influence people's thoughts, feelings and behavior across a variety of settings. Variation in personality is predictive of many outcomes in life, including mental health. Here we report on a meta-analysis of genome-wide association (GWA) data for personality in 10 discovery samples (17,375 adults) and five in silico replication samples (3294 adults).

Show morePersonality can be thought of as a set of characteristics that influence people's thoughts, feelings and behavior across a variety of settings. Variation in personality is predictive of many outcomes in life, including mental health. Here we report on a meta-analysis of genome-wide association (GWA) data for personality in 10 discovery samples (17,375 adults) and five in silico replication samples (3294 adults). All participants were of European ancestry. Personality scores for Neuroticism, Extraversion, Openness to Experience, Agreeableness and Conscientiousness were based on the NEO Five-Factor Inventory. Genotype data of ≈ 2.4M single-nucleotide polymorphisms (SNPs; directly typed and imputed using HapMap data) were available. In the discovery samples, classical association analyses were performed under an additive model followed by meta-analysis using the weighted inverse variance method. Results showed genome-wide significance for Openness to Experience near the RASA1 gene on 5q14.3 (rs1477268 and rs2032794, P=2.8 × 10(-8) and 3.1 × 10(-8)) and for Conscientiousness in the brain-expressed KATNAL2 gene on 18q21.1 (rs2576037, P=4.9 × 10(-8)). We further conducted a gene-based test that confirmed the association of KATNAL2 to Conscientiousness. In silico replication did not, however, show significant associations of the top SNPs with Openness and Conscientiousness, although the direction of effect of the KATNAL2 SNP on Conscientiousness was consistent in all replication samples. Larger scale GWA studies and alternative approaches are required for confirmation of KATNAL2 as a novel gene affecting Conscientiousness.

Title: Five-Factor Personality Traits and Age Trajectories of Self-Rated Health: The Role of Question Framing.
Creator: Löckenhoff, Corinna, Terracciano, Antonio, Ferrucci, Luigi, Costa, Paul
Abstract/Description: We examined the influence of personality traits on mean levels and age trends in 4 single-item measures of self-rated health: general rating, comparison to age peers, comparison to past health, and expectations for future health. Community-dwelling participants (N = 1,683) completed 7,474 self-rated health assessments over a period of up to 19 years. In hierarchical linear modeling analyses, age-associated declines differed across the 4 health items. Across age groups, high Neuroticism and...

Community-dwelling participants (N = 1,683) completed 7,474 self-rated health assessments over a period of up to 19 years. In hierarchical linear modeling analyses, age-associated declines differed across the 4 health items. Across age groups, high Neuroticism and low Conscientiousness, low Extraversion, and low Openness were associated with worse health ratings, with notable differences across the 4 health items. Furthermore, high Neuroticism predicted steeper declines in health ratings involving temporal comparisons. We consider theoretical implications regarding the mechanisms behind associations among personality traits and self-rated health.

Show moreHuman longevity and personality traits are both heritable and are consistently linked at the phenotypic level. We test the hypothesis that candidate genes influencing longevity in lower organisms are associated with variance in the five major dimensions of human personality (measured by the NEO-FFI and IPIP inventories) plus related mood states of anxiety and depression. Seventy single nucleotide polymorphisms (SNPs) in six brain expressed, longevity candidate genes (AFG3L2, FRAP1, MAT1A, MAT2A, SYNJ1, and SYNJ2) were typed in over 1,000 70-year old participants from the Lothian Birth Cohort of 1936 (LBC1936). No SNPs were associated with the personality and psychological distress traits at a Bonferroni corrected level of significance (P < 0.0002), but there was an over-representation of nominally significant (P < 0.05) SNPs in the synaptojanin-2 (SYNJ2) gene associated with agreeableness and symptoms of depression. Eight SNPs which showed nominally significant association across personality measurement instruments were tested in an extremely large replication sample of 17,106 participants. SNP rs350292, in SYNJ2, was significant: the minor allele was associated with an average decrease in NEO agreeableness scale scores of 0.25 points, and 0.67 points in the restricted analysis of elderly cohorts (most aged >60 years). Because we selected a specific set of longevity genes based on functional genomics findings, further research on other longevity gene candidates is warranted to discover whether they are relevant candidates for personality and psychological distress traits.

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 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 moreCollagen XIV is a fibril-associated collagen with an interrupted triple helix (FACIT). Previous studies have shown that this collagen type regulates early stages of fibrillogenesis in connective tissues of high mechanical demand. Mice null for Collagen XIV are viable, however formation of the interstitial collagen network is defective in tendons and skin leading to reduced biomechanical function. The assembly of a tightly regulated collagen network is also required in the heart, not only for structural support but also for controlling cellular processes. Collagen XIV is highly expressed in the embryonic heart, notably within the cardiac interstitium of the developing myocardium, however its role has not been elucidated. To test this, we examined cardiac phenotypes in embryonic and adult mice devoid of Collagen XIV. From as early as E11.5, Col14a1(-/-) mice exhibit significant perturbations in mRNA levels of many other collagen types and remodeling enzymes (MMPs, TIMPs) within the ventricular myocardium. By post natal stages, collagen fibril organization is in disarray and the adult heart displays defects in ventricular morphogenesis. In addition to the extracellular matrix, Col14a1(-/-) mice exhibit increased cardiomyocyte proliferation at post natal, but not E11.5 stages, leading to increased cell number, yet cell size is decreased by 3 months of age. In contrast to myocytes, the number of cardiac fibroblasts is reduced after birth associated with increased apoptosis. As a result of these molecular and cellular changes during embryonic development and post natal maturation, cardiac function is diminished in Col14a1(-/-) mice from 3 months of age; associated with dilation in the absence of hypertrophy, and reduced ejection fraction. Further, Col14a1 deficiency leads to a greater increase in left ventricular wall thickening in response to pathological pressure overload compared to wild type animals. Collectively, these studies identify a new role for type XIV collagen in the formation of the cardiac interstitium during embryonic development, and highlight the importance of the collagen network for myocardial cell survival, and function of the working myocardium after birth.

Title: Absence of Myocardial Thyroid Hormone Inactivating Deiodinase Results in Restrictive Cardiomyopathy in Mice.
Creator: Ueta, Cintia, Oskouei, Behzad, Olivares, Emerson, Pinto, Jose, Correa, Mayrin, Simovic, Gordana, Simonides, Warner, Hare, Joshua, Bianco, Antônio Carlos
Abstract/Description: Cardiac injury induces myocardial expression of the thyroid hormone inactivating type 3 deiodinase (D3), which in turn dampens local thyroid hormone signaling. Here, we show that the D3 gene (Dio3) is a tissue-specific imprinted gene in the heart, and thus, heterozygous D3 knockout (HtzD3KO) mice constitute a model of cardiac D3 inactivation in an otherwise systemically euthyroid animal. HtzD3KO newborns have normal hearts but later develop restrictive cardiomyopathy due to cardiac-specific...

Here, we show that the D3 gene (Dio3) is a tissue-specific imprinted gene in the heart, and thus, heterozygous D3 knockout (HtzD3KO) mice constitute a model of cardiac D3 inactivation in an otherwise systemically euthyroid animal. HtzD3KO newborns have normal hearts but later develop restrictive cardiomyopathy due to cardiac-specific increase in thyroid hormone signaling, including myocardial fibrosis, impaired myocardial contractility, and diastolic dysfunction. In wild-type littermates, treatment with isoproterenol-induced myocardial D3 activity and an increase in the left ventricular volumes, typical of cardiac remodeling and dilatation. Remarkably, isoproterenol-treated HtzD3KO mice experienced a further decrease in left ventricular volumes with worsening of the diastolic dysfunction and the restrictive cardiomyopathy, resulting in congestive heart failure and increased mortality. These findings reveal crucial roles for Dio3 in heart function and remodeling, which may have pathophysiologic implications for human restrictive cardiomyopathy.

Show moreCONTEXT: Recent studies have shown an association between cigarettes per day (CPD) and a nonsynonymous single-nucleotide polymorphism in CHRNA5, rs16969968. OBJECTIVE: To determine whether the association between rs16969968 and smoking is modified by age at onset of regular smoking. DATA SOURCES: Primary data. STUDY SELECTION: Available genetic studies containing measures of CPD and the genotype of rs16969968 or its proxy. DATA EXTRACTION: Uniform statistical analysis scripts were run locally. Starting with 94,050 ever-smokers from 43 studies, we extracted the heavy smokers (CPD >20) and light smokers (CPD ≤10) with age-at-onset information, reducing the sample size to 33,348. Each study was stratified into early-onset smokers (age at onset ≤16 years) and late-onset smokers (age at onset >16 years), and a logistic regression of heavy vs light smoking with the rs16969968 genotype was computed for each stratum. Meta-analysis was performed within each age-at-onset stratum. DATA SYNTHESIS: Individuals with 1 risk allele at rs16969968 who were early-onset smokers were significantly more likely to be heavy smokers in adulthood (odds ratio [OR] = 1.45; 95% CI, 1.36-1.55; n = 13,843) than were carriers of the risk allele who were late-onset smokers (OR = 1.27; 95% CI, 1.21-1.33, n = 19,505) (P = .01). CONCLUSION: These results highlight an increased genetic vulnerability to smoking in early-onset smokers.
