RESUMO

OBJECTIVE: Emerging research challenges the one-factor model of the future time perspective (FTP) scale by demonstrating two- and three-factor models of the FTP scale. METHOD: Three samples (i.e., Switzerland and the United States; N = 2022) explored the factor structure, age pattern differences, tested the link between FTP factors, psychological well-being, and life satisfaction, as well as age as a moderator. RESULTS: We distinguished FTP into opportunities, extension, and constraint factors that corroborated previous research. We did not find a replicable curvilinear age pattern difference on any of the FTP factors. The association between extension and life satisfaction was stronger among younger than older adults. Alternatively, the association between constraint and life satisfaction was stronger among younger than older adults in Samples A and C, and the pattern was reversed in Sample B. Lastly, the association between constraint and environmental mastery was stronger among older adults than younger adults in Sample B and the pattern was reversed in Sample C. CONCLUSION: This variation in the perception of the future is different for people at different periods in life and has an important consequence for living life well, especially a focus on extension and lack of constraint.

RESUMO

Tartary buckwheat belongs to the family Polygonaceae, which is a traditionally edible and medicinal plant. Due to its various bioactive compounds, the consumption of Tartary buckwheat is correlated to a wide range of health benefits, and increasing attention has been paid to its potential as a functional food. This review summarizes the main bioactive compounds and important bioactivities and health benefits of Tartary buckwheat, emphasizing its protective effects on metabolic diseases and relevant molecular mechanisms. Tartary buckwheat contains a wide range of bioactive compounds, such as flavonoids, phenolic acids, triterpenoids, phenylpropanoid glycosides, bioactive polysaccharides, and bioactive proteins and peptides, as well as D-chiro-inositol and its derivatives. Consumption of Tartary buckwheat and Tartary buckwheat-enriched products is linked to multiple health benefits, e.g., antioxidant, anti-inflammatory, antihyperlipidemic, anticancer, antidiabetic, antiobesity, antihypertensive, and hepatoprotective activities. Especially, clinical studies indicate that Tartary buckwheat exhibits remarkable antidiabetic activities. Various tartary buckwheat -based foods presenting major health benefits as fat and blood glucose-lowering agents have been commercialized. Additionally, to address the safety concerns, i.e., allergic reactions, heavy metal and mycotoxin contaminations, the quality control standards for Tartary buckwheat and its products should be drafted and completed in the future.

RESUMO

Does being disagreeable-that is, behaving in aggressive, selfish, and manipulative ways-help people attain power? This question has long captivated philosophers, scholars, and laypeople alike, and yet prior empirical findings have been inconclusive. In the current research, we conducted two preregistered prospective longitudinal studies in which we measured participants' disagreeableness prior to entering the labor market and then assessed the power they attained in the context of their work organization ∼14 y later when their professional careers had unfolded. Both studies found disagreeable individuals did not attain higher power as opposed to extraverted individuals who did gain higher power in their organizations. Furthermore, the null relationship between disagreeableness and power was not moderated by individual differences, such as gender or ethnicity, or by contextual variables, such as organizational culture. What can account for this null relationship? A close examination of behavior patterns in the workplace found that disagreeable individuals engaged in two distinct patterns of behavior that offset each other's effects on power attainment: They engaged in more dominant-aggressive behavior, which positively predicted attaining higher power, but also engaged in less communal and generous behavior, which predicted attaining less power. These two effects, when combined, appeared to cancel each other out and led to a null correlation between disagreeableness and power.

RESUMO

OBJECTIVES: The assessment of personality traits is most often based on self-report. However, a growing body of research has shown that informant-report is a valuable and too often overlooked source of unique information. The aim of this study was to validate the French version of the informant-report form of the Big Five Inventory-2 (BFI-2) which assesses 15 facet traits in addition to the five major trait domains. METHODS: We asked 699 psychology and sports science and technology students to describe a person they knew well using the BFI-2 and obtained 661 valid records with demographic information. The data were analyzed using a bi-factor exploratory structural equation model with five bifactors corresponding to the Big Five domains, and three group factors (facets) each. RESULTS: This model had an excellent overall fit. Cronbach's alpha coefficients for the five domains were very satisfactory and the McDonald's omega coefficients were even better. The scales that measured the five major factors were therefore highly reliable, although Extraversion was somewhat less so. The scales measuring facets all had high reliability as measures of the whole formed by the major factor and the group factor. In addition, ten of them were reliable measures of their specific factor, and the remaining five appeared to be pure measures of the five domains. CONCLUSIONS: The informant-report form of the BFI-2 is a reliable instrument which is easy and quick to administer. These qualities should enable clinicians and researchers to exploit the much-neglected source of original information provided by informant-reports.

RESUMO

Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review the sources, formation, occurrence, toxicity and remediation methods of microplastics. We distinguish ocean-based and land-based sources of microplastics. Microplastics have been found in biological samples such as faeces, sputum, saliva, blood and placenta. Cancer, intestinal, pulmonary, cardiovascular, infectious and inflammatory diseases are induced or mediated by microplastics. Microplastic exposure during pregnancy and maternal period is also discussed. Remediation methods include coagulation, membrane bioreactors, sand filtration, adsorption, photocatalytic degradation, electrocoagulation and magnetic separation. Control strategies comprise reducing plastic usage, behavioural change, and using biodegradable plastics. Global plastic production has risen dramatically over the past 70 years to reach 359 million tonnes. China is the world's top producer, contributing 17.5% to global production, while Turkey generates the most plastic waste in the Mediterranean region, at 144 tonnes per day. Microplastics comprise 75% of marine waste, with land-based sources responsible for 80-90% of pollution, while ocean-based sources account for only 10-20%. Microplastics induce toxic effects on humans and animals, such as cytotoxicity, immune response, oxidative stress, barrier attributes, and genotoxicity, even at minimal dosages of 10 µg/mL. Ingestion of microplastics by marine animals results in alterations in gastrointestinal tract physiology, immune system depression, oxidative stress, cytotoxicity, differential gene expression, and growth inhibition. Furthermore, bioaccumulation of microplastics in the tissues of aquatic organisms can have adverse effects on the aquatic ecosystem, with potential transmission of microplastics to humans and birds. Changing individual behaviours and governmental actions, such as implementing bans, taxes, or pricing on plastic carrier bags, has significantly reduced plastic consumption to 8-85% in various countries worldwide. The microplastic minimisation approach follows an upside-down pyramid, starting with prevention, followed by reducing, reusing, recycling, recovering, and ending with disposal as the least preferable option.

RESUMO

BACKGROUND: Transgender individuals are considered at high risk of contracting HIV infection. Integrating HIV testing and counseling (HTC) services into current transgender health programs is necessary to increase its uptake. Our study aimed to describe the characteristics of trans men (TM) and trans women (TW) who accessed HTC services in a community-based transgender health center in Metro Manila, Philippines, and to examine the relationship between gender identity and their non-uptake of HIV testing.  METHODS: We conducted a cross-sectional study of TM and TW seeking care from 2017 to 2019. Medical records of clients were reviewed to ascertain their age, gender identity, year and frequency of clinic visits, lifestyle factors, and non-uptake of HIV testing. The effect of gender identity on the non-uptake of HIV testing was estimated using a generalized linear model with Poisson distribution, log link function, and a robust variance, adjusted for confounding variables.  RESULTS: Five hundred twenty-five clients were included in the study, of which about 82.3% (432/525) of the clients declined the HTC services being offered. In addition, the prevalence of non-uptake of HIV testing was 48% higher (Adjusted Prevalence Ratio: 1.48; 95% Confidence Interval: 1.31-1.67) among TM compared to TW. Approximately 3.7% (1/27) and 10.6% (7/66) of the TM and TW, respectively, who accessed the HTC services were reactive. Moreover, most reactive clients were on treatment 87.5% (7/8); three were already virally suppressed, four were on ART but not yet virally suppressed, and one TW client was lost to follow up. CONCLUSION: The non-uptake of HTC service of TM and TW is high. HIV program implementers should strategize solutions to reach this vulnerable population for increased and better HTC service uptake and linkage to care.

RESUMO

OBJECTIVE: Many studies have demonstrated that personality traits predict academic performance for students in high school and college. Much less evidence exists on whether the relationship between personality traits and academic performance changes from childhood to adolescence, and existing studies show very mixed findings. This study tests one hypothesis-that the importance of Agreeableness, Emotional Stability, and Conscientiousness for academic performance changes fundamentally during school-against an alternative hypothesis suggesting that the changing relationships found in previous research are largely measurement artifacts. METHOD: We used a nationwide sample of 135,389 primary and lower secondary students from Grade 4 to Grade 8. We replicated all results in a separate sample of another 127,375 students. RESULTS: We found that academic performance was equally strongly related to our measure of Conscientiousness at all these grade levels, and the significance of Agreeableness and Emotional Stability predominantly reflected their connections with Conscientiousness. However, age also appeared to shape the relationship between Emotional Stability and performance. CONCLUSION: Amidst the replication crisis in psychology these findings demonstrate a very stable and predictable relationship between personality traits and academic performance, which may have important implications for the education of children already in primary school.

RESUMO

This series of studies investigated whether the good psychometric properties of the English version of the Big Five Inventory-2 (BFI-2) could be replicated using its Dutch adaptation. Second, it aimed to further examine the predictive validity of both the Big Five domain and the more specific facet scales of the BFI-2 in a large and representative sample. Results indicated that the structure found in the English version was replicated in the Dutch adaptation. The 60-item BFI-2 was reliable at the level of both domains and facets, as were the abbreviated versions. In terms of validity, the domain scales predicted a broad range of criteria. Examination of preregistered hypotheses regarding the discriminant validity of the facets indicated that experts were able to predict which facets would be most strongly associated with specific criteria. Overall, results confirm the strong psychometric properties of the BFI-2 Big Five domain scales and indicate that theoretically identified facets can be more valid predictors of criteria than other facets of the same domain.

RESUMO

The continued and extended use of nuclear power is often considered and discussed as a viable energy policy option to meet energy demands while also meeting national CO2 emission reduction goals. A central issue in energy policy for sustainability is the question of nuclear reactor safety. However, studies on nuclear reactor safety often run up against the problem of estimating the probability of a major accident from patchy and limited empirical data. Here, we describe a simple probabilistic model of catastrophic nuclear reactor accidents based on a set of four assumptions. The model treats the accident probability in each of n reactors as a variable and returns the probability of a major accident in the reactor fleet. We find that, at 99.5% reactor safety, the probability of another Chernobyl- or Fukushima-sized event is 49% for the global fleet, and that safety would have to be 99.96% in order to bring that probability below 5%. We discuss our findings in light of the debate on energy policy for sustainability.

RESUMO

Metabolic syndrome is a cluster of disorders that increase the risk of cardiovascular disease and diabetes. This study has investigated the responses to rind of yellow mangosteen (Garcinia dulcis), usually discarded as waste, in a rat model of human metabolic syndrome. The rind contains higher concentrations of phytochemicals (such as garcinol, morelloflavone and citric acid) than the pulp. Male Wistar rats aged 8-9 weeks were fed either corn starch diet or high-carbohydrate, high-fat diet for 16 weeks, which were supplemented with 5% freeze-dried G. dulcis fruit rind powder during the last 8 weeks. We characterised metabolic, cardiovascular, liver and gut microbiota parameters. High-carbohydrate, high-fat diet-fed rats developed abdominal obesity, hypertension, increased left ventricular diastolic stiffness, decreased glucose tolerance, fatty liver and reduced Bacteroidia with increased Clostridia in the colonic microbiota. G. dulcis fruit rind powder attenuated these changes, improved cardiovascular and liver structure and function, and attenuated changes in colonic microbiota. G. dulcis fruit rind powder may be effective in metabolic syndrome by appetite suppression, inhibition of inflammatory processes and increased fat metabolism, possibly related to changes in the colonic microbiota. Hence, we propose the use of G. dulcis fruit rind as a functional food to ameliorate symptoms of metabolic syndrome.

RESUMO

BACKGROUND AND OBJECTIVES: Close observation may be an appropriate alternative to completion lymph node dissection (CLND) for selected patient populations, especially those with minimal tumor burden in the sentinel lymph node (SLN). In this study, we examined the practice patterns of CLND utilization. METHODS: Using the National Cancer Database, we examined CLND utilization in SLN-positive patients diagnosed with clinically node-negative Stage III melanoma from 2012 to 2015. Hierarchical logistic regression models were constructed to assess the factors associated with observation after positive SLN biopsy (SLNB). RESULTS: Of the 131 171 patients identified, 55 688 (42.5%) underwent SLNB and 7200 (12.9%) had an SLN with a metastatic disease. CLND was performed in 57.0% of the patients with a positive SLNB. Patients were more likely to forgo CLND if the primary tumor was located on the lower extremity (odds ratio [OR], 1.65, 95% confidence interval [CI], 1.40-1.94), were older (P < 0.001), had multiple comorbidities (OR, 1.61, 95% CI, 1.19-2.20), or were diagnosed with melanoma in 2015 (OR, 1.33, 95% CI, 1.13-1.56 vs 2012). CONCLUSIONS: CLND utilization varied based on patient factors and decreased over time. As evidence supports close observation in selected patient populations with low SLN tumor burden, monitoring is needed to ensure that CLND is performed in the appropriate patient populations. However, this will require improvements in the data collected by cancer registries.

RESUMO

The elucidation of protein-protein interactions is vital for determining the function and action of quaternary protein structures. Here, we discuss the difficulty and importance of establishing protein quaternary structure and review in vitro and in silico methods for doing so. Determining the interacting partner proteins of predicted protein structures is very time-consuming when using in vitro methods, this can be somewhat alleviated by use of predictive methods. However, developing reliably accurate predictive tools has proved to be difficult. We review the current state of the art in predictive protein interaction software and discuss the problem of scoring and therefore ranking predictions. Current community-based predictive exercises are discussed in relation to the growth of protein interaction prediction as an area within these exercises. We suggest a fusion of experimental and predictive methods that make use of sparse experimental data to determine higher resolution predicted protein interactions as being necessary to drive forward development.

RESUMO

Cancer prevention is central to the mission of the American Cancer Society (ACS). The ACS's prevention activities take many forms, but are primarily focused on modifiable risk factors that have been demonstrated to have the largest impact on cancer risk in the general population (with particular emphasis on tobacco use because of its large impact on cancer), and well-proven policy and program interventions. The ACS addresses nutrition, physical inactivity and obesity, alcohol consumption, excessive sun exposure, prevention of certain chronic infections, and selected other environmental factors through a variety of venues, including consensus guidelines (eg, nutrition and physical activity, human papillomavirus vaccination) and developing educational materials for health care providers and the general public. In contrast to the broad definition of environmental factors used by the ACS and most other public health agencies, some members of the general public associate the term "environmental" only with toxic air and water pollutants and other, predominantly manmade, hazards that people encounter, often involuntarily, in their daily life. This article will provide an overview of the ACS's approach to the prevention of cancer associated with such toxic pollutants in the context of its mission and priorities with respect to cancer prevention.

RESUMO

Resting state fMRI may help identify markers of risk for affective disorder. Given the comorbidity of anxiety and depressive disorders and the heterogeneity of these disorders as defined by DSM, an important challenge is to identify alterations in resting state brain connectivity uniquely associated with distinct profiles of negative affect. The current study aimed to address this by identifying differences in brain connectivity specifically linked to cognitive and physiological profiles of anxiety, controlling for depressed affect. We adopted a two-stage multivariate approach. Hierarchical clustering was used to independently identify dimensions of negative affective style and resting state brain networks. Combining the clustering results, we examined individual differences in resting state connectivity uniquely associated with subdimensions of anxious affect, controlling for depressed affect. Physiological and cognitive subdimensions of anxious affect were identified. Physiological anxiety was associated with widespread alterations in insula connectivity, including decreased connectivity between insula subregions and between the insula and other medial frontal and subcortical networks. This is consistent with the insula facilitating communication between medial frontal and subcortical regions to enable control of physiological affective states. Meanwhile, increased connectivity within a frontoparietal-posterior cingulate cortex-precunous network was specifically associated with cognitive anxiety, potentially reflecting increased spontaneous negative cognition (e.g., worry). These findings suggest that physiological and cognitive anxiety comprise subdimensions of anxiety-related affect and reveal associated alterations in brain connectivity.

RESUMO

BACKGROUND: Acute respiratory distress syndrome (ARDS) is a potentially devastating refractory hypoxemic illness with multi-organ involvement. Although several randomised controlled trials into ventilator and fluid management strategies have provided level 1 evidence to guide supportive therapy, there are few, established guidelines on how to manage patients with ARDS. In addition, and despite their continued use, pharmacotherapies for ARDS disease modulation have no proven benefit in improving mortality. Little is known however about the variability in diagnostic and treatment practices across the United Kingdom (UK). The aim of this survey, therefore, was to assess the use of diagnostic criteria and treatment strategies for ARDS in critical care units across the UK. METHODS: The survey questionnaire was developed and internally piloted at University Hospital Southampton NHS Foundation Trust. Following ethical approval from University of Southampton Ethics and Research Committee, a link to an online survey engine (Survey Monkey) was then placed on the Intensive Care Society (UK) website. Fellows of The Intensive Care Society were subsequently personally approached via e-mail to encourage participation. The survey was conducted over a period of 3 months. RESULTS: The survey received 191 responses from 125 critical care units, accounting for 11% of all registered intensive care physicians at The Intensive Care Society. The majority of the responses were from physicians managing general intensive care units (82%) and 34% of respondents preferred the American European Consensus Criteria for ARDS. There was a perceived decline in both incidence and mortality in ARDS. Primary ventilation strategies were based on ARDSnet protocols, though frequent deviations from ARDSnet positive end expiratory pressure (PEEP) recommendations (51%) were described. The majority of respondents set permissive blood gas targets (hypoxia (92%), hypercapnia (58%) and pH (90%)). The routine use of pharmacological agents is rare. Neuromuscular blockers and corticosteroids are considered occasionally and on a case-by-case basis. Routine (58%) or late (64%) tracheostomy was preferred to early tracheostomy insertion. Few centres offered routine follow-up or dedicated rehabilitation programmes following hospital discharge. CONCLUSIONS: There is substantial variation in the diagnostic and management strategies employed for patients with ARDS across the UK. National and/or international guidelines may help to improve standardisation in the management of ARDS.

RESUMO

The present research was conducted to map the hierarchical structure of youths' personality traits, to identify the foundational level of this structure, and to test whether the meanings of some youth personality dimensions shift with age. We addressed these issues by analyzing personality parent reports describing a cross-sectional sample of 16,000 children, adolescents, and young adults (ages 3 to 20). These parent reports were made using a broadband measure of youths' personal characteristics, the common-language California Child Q-Set. Analyses of the full sample and comparisons of 16 age groups supported three main conclusions. First, the hierarchical structure of youths' personality traits both resembles and differs from the adult personality hierarchy in important ways. Second, a set of six dimensions--Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness to Experience, and Activity--may constitute the foundational level of the youth personality hierarchy from middle childhood through adolescence. This "Little Six" structure represents a union of the most prominent personality and temperament dimensions. Third, the meanings of some youth personality dimensions (e.g., Activity, Conscientiousness) shift systematically with age. These findings advance our understanding of when and how personality structure develops during the first two decades of life.

RESUMO

Attention-deficit/hyperactivity disorder (ADHD) is a childhood-onset neurodevelopmental condition characterized by developmentally extreme and impairing symptoms of inattention and/or hyperactivity/impulsivity. Great interest has emerged in the ways ADHD and its underlying symptom dimensions relate to the development of personality traits. Much extant research on this topic is cross-sectional, relying on self-report measures and male samples. Herein, we present data from a prospective, longitudinal study of a socioeconomically and racially diverse sample of girls, including those with ADHD and a matched neurotypical comparison sample. We examined how parent- and teacher-reported ADHD in middle childhood relate to self-reported Big Five personality traits in adolescence. As expected, childhood ADHD diagnosis prospectively predicted lower self-reported Conscientiousness, lower Agreeableness, and higher Neuroticism in adolescence. With ADHD diagnosis covaried, Inattention (IA) predicted only low Conscientiousness, Hyperactivity/Impulsivity (HI) predicted only low Agreeableness, and neither predicted adolescent Neuroticism. An exploratory moderator analysis showed that family income moderated the effects of IA and HI on the negativity of adolescent self-descriptions of their own personalities, with more pronounced negative effects for girls in families with higher (rather than lower) income. Familial pressures to achieve in higher-income families may be linked to more pronounced negative ramifications of ADHD on personality development.

RESUMO

OBJECTIVE: The purpose of this study was to describe a new computer-controlled research apparatus for measuring in vivo uterine ligament force-displacement behavior and stiffness and to present pilot data for women with and without prolapse. STUDY DESIGN: Seventeen women with varying uterine support underwent testing in the operating room (OR) after anesthetic induction. A tripod-mounted computer-controlled linear servoactuator was used to quantify force-displacement behavior of the cervix and supporting ligaments. The servoactuator applied a caudally directed force to a tenaculum at 4 mm/sec velocity until the traction force reached 17.8 N (4 lbs). Cervix location on Pelvic Organ Prolapse Quantification system (POP-Q) in the clinic, in the OR, at rest, and with minimal force (<1.1 N); maximum force (17.8 N) was recorded. Ligament "stiffness" between minimum and maximum force was calculated. RESULTS: The mean ± SD subject age was 54.5 ± 12.7 years; parity was 2.9 ± 1.1; body mass index was 29.0 ± 4.3 kg/m(2), and POP-Q point C was -3.1 ± 3.9 cm. POP-Q point C was correlated most strongly with cervix location at maximum force (r = +0.68; P = .003) and at rest (r = +0.62; P = .009). Associations between cervix location at minimum force (r = +0.46; P = .059) and ligament stiffness (r = -0.44; P = .079) were not statistically significant. Cervix location in the OR with minimal traction lay below the lowest point found on POP-Q for 13 women. CONCLUSION: POP-Q point C was correlated strongly with cervix location at rest and at maximum traction force; however, only 19% of the variation in POP-Q point C location was explained by ligament stiffness. The cervix location in the OR at minimal traction lay below POP-Q point C value in three-fourths of the women.

OBJECTIVE: Although Loevinger's model of ego development is a theory of personality growth, there are few studies that have examined age-related change in ego level over developmentally significant periods of adulthood. To address this gap in the literature, we examined mean-level change and individual differences in change in ego level over 18 years of midlife. METHOD: In this longitudinal study, participants were 79 predominantly White, college-educated women who completed the Washington University Sentence Completion Test in early (age 43) and late (age 61) midlife as well as measures of the trait of Openness (ages 21, 43, 52, and 61) and accommodative processing (assessed from narratives of difficult life events at age 52). RESULTS: As hypothesized, the sample overall showed a mean-level increase in ego level from age 43 to age 61. Additionally, a regression analysis showed that both the trait of Openness at age 21 and accommodative processing of difficult events that occurred during (as opposed to prior to) midlife were each predictive of increasing ego level from age 43 to age 61. CONCLUSIONS: These findings counter prior claims that ego level remains stable during adulthood and contribute to our understanding of the underlying processes involved in personality growth in midlife.

RESUMO

Although the objective conditions of people's lives are fairly stable from day to day, daily life can feel like an emotional rollercoaster. For some people, life satisfaction hitches a ride on the emotional rollercoaster (i.e., momentary emotions spill over into broader evaluations of life). The extent to which positive and negative emotions spill over into life satisfaction is referred to as positive and negative emotion globalizing. Initial evidence suggests that emotion globalizing varies between individuals and is linked to a maladaptive psychological profile. Integrating a lifespan perspective, this is the first study to identify and describe age differences in emotion globalizing using data from two adult community samples (Study 1: N = 133 women, age range = 23-78; Study 2: N = 137, age range = 18-95). Further, we tested key boundary conditions of emotion globalizing by examining two types of emotions (i.e., current or after most stressful event of the day) and two types of satisfaction (i.e., overall life satisfaction [life satisfaction] or current day satisfaction [day satisfaction]). Specifically, we investigated how younger and older adults differed in the associations of current emotions with life satisfaction (i.e., emotion globalizing; Study 1), stressor-related emotions with life satisfaction (i.e., stressor-related emotion globalizing; Study 1), and stressor-related emotions with day satisfaction (Study 2). Results revealed that older (compared to younger) adults exhibited less negative (but not positive) emotion globalizing and stressor-related emotion globalizing. We found no age differences in the association between stressor-related emotions and day satisfaction. These findings extend insights into emotion globalizing and inform theories of emotional aging.
