This article contributes to a more systematic understanding of the role of mainstream media in deliberative processes by analyzing how inclusive local newspapers are of diverse perspectives on the Terri Schiavo case. Using both Pearson’s chi-square test and multinomial logistic regression, we assess how ownership, state political ideology, geographic location, and news format affect what ideas are included in the debate over whether Terri Schiavo’s hydration and nutrition tubes should be removed as well as the tone with which these ideas are discussed. We find that mainstream newspapers are relatively inclusive of diverse ideas and perspectives—regardless of whether the newspaper is independently or corporately owned, the political leanings of the target audience, and the geographic location of the outlet. However, we also find that local newspapers do significantly differ from one another in terms of the frequency and tone with which they include diverse viewpoints. Our research suggests that local outlets downplay ideas that are likely to be regarded as controversial by their target audiences. We conclude with a discussion of the implications of this research for understanding the role of media in deliberative democratic processes in the United States. PMID:26120237

The Origin of The Piz Terri-Lunschania zone (Central Alps, Switzerland)

NASA Astrophysics Data System (ADS)

Galster, Federico; Stockli, Daniel

2017-04-01

The Piz Terri-Lunschania zone (PTLZ) represents a band of metasedimentary rocks embedded in a crucial knot at the NE border of the Lepontine dome, at the intersection of the Gotthard, Lucomagno, Simano, Adula and Grava nappes. Its origin and its position in the tectonostratigraphy of the Central Alps are still not completely understood. A better understanding of this sedimentary zone and its tectonic position could shed lights on the Helvetic-Penninic connection and facilitate the disentanglement of the Lepontine dome tectonics. In this study we combine structural and stratigraphic observations with detrital zircon (DZ) and detrital rutile (DR) U-Pb geochronology as well as mineral trace element data from Permian, Triassic and Jurassic sandstones. We compare these data with those from adjacent tectonic units and coeval strata in other portions of the Alpine chain. Maximal depositional ages, abrupt changes in provenances and stratigraphic correlations based on new DZ and DR U-Pb and trace element data allow for a better understanding of the sedimentary evolution of the Terri basin and its palaeogeographic position along the northern margin of the Alpine Tethys. In particular the DZ U-Pb signatures, with its abundant 260-280 Ma zircons and the scarcity of 290-350 Ma zircons, corroborates an Ultra-Adula origin of the PTLZ as proposed by Galster et al (2010; 2012) based on stratigraphic arguments and reinforces the notion of a Briançonnais influence on the stratigraphic record of this complex zone, a fact that has important tectonic and Palaeogeographic implications.

Kirk, Susan

2008-11-01

To obtain a profile of children and young people in north west England who needed the ongoing support of medical technology. As part of a larger study, 28 community children's nursing teams in the north west of England were asked to profile the children and young people on their caseloads who needed the ongoing support of medical technology. Twenty-five teams returned data, from which a total of 591 children and young people were identified. The most prevalent technology used was gastrostomy/jejunostomy, which was used by more than two-thirds of the sample. Over a quarter of the children/young people were supported by more than one technology. The majority of the children/young people were seven years old or younger Although most had used the technology for five years or less (71 per cent), there were 164 children/ young people who had been technology-assisted for six or more years. Although there are limitations in this study, the data is nevertheless useful for planning future services and support, including identifying the numbers of young people who will be transferring to adult services. A more efficient means of collecting these data would be to systematically record long-term conditions and technology assistance in electronic health records.

Middle-aged adults with ideal blood pressure, cholesterol, and glucose levels exhibit substantially lower cardiovascular mortality than those with unfavorable levels. Four healthy lifestyle components-optimal body weight, diet, physical activity, and not smoking-are recommended for cardiovascular health (CVH). This study quantified associations between combinations of healthy lifestyle components measured in young adulthood and loss of the ideal CVH profile into middle age. Analyses included 2164 young adults in the Coronary Artery Risk Development in Young Adults study with the ideal CVH profile (defined as untreated blood pressure <120/80 mm Hg, total cholesterol <200 mg/dL, fasting blood glucose <100 mg/dL, and absence of cardiovascular disease) at baseline. Cox proportional hazards regression models estimated hazard ratios for loss of the ideal CVH profile over 25 years according to 4 individual and 16 combinations of optimal healthy lifestyle components measured in young adulthood: body mass index, physical activity, nonsmoking status, and diet quality. Models were adjusted for age, sex, race, education, study center, and baseline blood pressure, cholesterol, and glucose. Eighty percent (n=1737) of participants lost the ideal CVH profile by middle age; loss was greatest for young adults with no optimal healthy lifestyle components at baseline. Relative to young adults with no optimal healthy lifestyle components, those with all 4 were less likely to lose the ideal CVH profile (hazard ratio 0.59, 95% CI 0.44-0.80). Combinations that included optimal body mass index and nonsmoking status were each associated with lower risk. Optimal body mass index and not smoking in young adulthood were protective against loss of the ideal CVH profile through middle age. Importance of diet and physical activity may be included through their effects on healthy weight. © 2015 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.

Geological modeling of a fault zone in clay rocks at the Mont-Terri laboratory (Switzerland)

Kakurina, M.; Guglielmi, Y.; Nussbaum, C.; Valley, B.

Clay-rich formations are considered to be a natural barrier for radionuclides or fluids (water, hydrocarbons, CO2) migration. However, little is known about the architecture of faults affecting clay formations because of their quick alteration at the Earth's surface. The Mont Terri Underground Research Laboratory provides exceptional conditions to investigate an un-weathered, perfectly exposed clay fault zone architecture and to conduct fault activation experiments that allow explore the conditions for stability of such clay faults. Here we show first results from a detailed geological model of the Mont Terri Main Fault architecture, using GoCad software, a detailed structural analysis of 6 fully cored and logged 30-to-50m long and 3-to-15m spaced boreholes crossing the fault zone. These high-definition geological data were acquired within the Fault Slip (FS) experiment project that consisted in fluid injections in different intervals within the fault using the SIMFIP probe to explore the conditions for the fault mechanical and seismic stability. The Mont Terri Main Fault "core" consists of a thrust zone about 0.8 to 3m wide that is bounded by two major fault planes. Between these planes, there is an assembly of distinct slickensided surfaces and various facies including scaly clays, fault gouge and fractured zones. Scaly clay including S-C bands and microfolds occurs in larger zones at top and bottom of the Mail Fault. A cm-thin layer of gouge, that is known to accommodate high strain parts, runs along the upper fault zone boundary. The non-scaly part mainly consists of undeformed rock block, bounded by slickensides. Such a complexity as well as the continuity of the two major surfaces are hard to correlate between the different boreholes even with the high density of geological data within the relatively small volume of the experiment. This may show that a poor strain localization occurred during faulting giving some perspectives about the potential for

Young patients (<50years) exhibit specific characteristics in chronic heart failure (HF), but their phenotype in acute heart failure (AHF) is not well described. 2033 patients of the PROTECT trial were divided into two groups: young patients (≤50years) and older patients (>50years). Biomarkers from different pathophysiological domains were available in 1266 patients. Patients were compared with regard to clinical characteristics, biomarker profiles, and in-hospital (worsening renal function [WRF] and decongestion) and post-discharge (180-day survival) outcome. Young patients (n=121) were mostly men, had fewer comorbidities with better renal function, and more often had a reduced ejection fraction. At admission, young patients were more likely to have jugular venous distension, but less rales and dyspnea compared with older patients. During hospitalization, young patients received higher loop diuretic doses and were decongested earlier than older patients. WRF occurred less frequently in young patients (5.9% vs. 13.3%, p=0.020) and they were more often discharged alive. At 180days, the mortality of young patients was lower than that of the older patients (9.9% vs. 18.1, p=0.021). Biomarker levels indicative of inflammation and renal damage were lower in the young, although they exhibited higher BNP levels than older patients. Despite use of higher diuretic doses, young patients with AHF less often developed WRF during hospitalization and had better outcomes than older patients. Differences in biomarker levels between the age groups suggest distinct underlying pathophysiologies. https://clinicaltrials.gov numbers NCT00328692 and NCT00354458. Copyright © 2016.

Williams syndrome (WS) is a genetic disorder causing intellectual disability. Children with WS often exhibit various kinds of maladaptive behaviours that affect their social functioning. In order to determine whether these behaviours are syndrome-specific, it would be necessary to compare children with WS with children with other syndromes as well as to provide data on the socio-emotional profile in WS from a variety of cultures. The present study investigated the behavioural profile and its relation to maternal stress in Greek young children with WS in comparison with young children with Down syndrome and typically developing (TD) children. Participants were 60 mothers, 20 in each syndrome group and 20 in the control group. The three groups were matched for mental age. The behavioural profile of the participants was investigated through the Child Behaviour Checklist (1.5-5 years) and maternal stress through the Parental Stress Index. In accordance with studies in other cultures, it was found that young children with WS received significantly higher rates in emotional problems and anxiety/depression, compared with both children with Down syndrome and TD children. Moreover, mothers of children with WS reported significantly higher scores in the Total Stress index compared with mothers of TD children. However, in contrast with previous studies, only 25% of children with WS fell into the clinical range in the total Child Behavior Checklist score. The consistency of the socio-emotional characteristics of children with WS across cultures and developmental stages implies a strong influence of the genetic phenotype. However, Greek mothers avoided to characterize these behaviours as pathological. Implications of these findings for clinical practice are also discussed. © 2011 Blackwell Publishing Ltd.

Distinct health behavior and psychosocial profiles of young adult survivors of childhood cancers: a mixed methods study.

We used a mixed-methods approach to examine health behavior profiles of young adult cancer survivors and characterize related sociodemographic and psychosocial factors. We conducted a mail-based survey assessing sociodemographics, cancer treatment, health behaviors (e.g., tobacco use, physical activity), healthcare provider interactions, and psychosocial factors (e.g., Profile of Moods States [POMS]) among 106 young adult survivors from a southeastern cancer center and semi-structured interviews among a subset of 26. A k-means cluster analysis using eight health behaviors yielded three distinct health behavior profiles: high risk (n = 25), moderate risk (n = 39), and low risk (n = 40). High risks had the highest current alcohol, tobacco, and marijuana use; physical activity; and number of sexual partners (p's < 0.001). They had higher symptoms of POMS tension-anxiety, depression-dejection, fatigue-inertia, and confusion-bewilderment (p's < 0.05). Moderate risks had lowest physical activity (p < 0.05) but otherwise had moderate health behaviors. Low risks had the lowest alcohol, tobacco, and marijuana use and fewest sexual partners (p's < 0.05). They had the lowest levels of tension-anxiety, depression-dejection, fatigue-inertia, and confusion-bewilderment (p's < 0.05). Qualitative interviews showed that cancer had a range of effects on health behaviors and variable experiences regarding how healthcare providers address these behaviors. Assessing health behavior profiles, rather than individual health behaviors, is informative in characterizing young adult cancer survivors and targeting survivorship care. Young adult cancer survivors demonstrate distinct health behavior profiles and are differentially impacted by the experience of cancer. Healthcare providers should be consistently intervening to ensure that survivors understand their specific health risks.

Argillaceous formations generally act as aquitards because of their low hydraulic conductivities. This property, together with the large retention capacity of clays for cationic contaminants and the potential for self-sealing, has brought clay formations into focus as potential host rocks for the geological disposal of radioactive waste. Excavated in the Opalinus Clay formation, the Mont Terri underground rock laboratory in the Jura Mountains of NW Switzerland is an important international test site for researching clay formations. Research is carried out in the underground facility, which is located adjacent to the security gallery of the Mont Terri motorway tunnel. Fifteen partners from European countries, USA, Canada and Japan participate in the project. The objectives of the research program are to analyze the hydrogeological, geochemical and rock mechanical properties of the Opalinus Clay, to determine the changes induced by the excavation of galleries and by heating of the rock formation, to test sealing and container emplacement techniques and to evaluate and improve suitable investigation techniques. For the safety of deep geological disposal, it is of key importance to understand the processes occurring in the undisturbed argillaceous environment, as well as the processes in a disturbed system, during the operation of the repository. The objectives are related to: 1. Understanding processes and mechanisms in undisturbed clays and 2. Experiments related to repository-induced perturbations. Experiments of the first group are dedicated to: i) Improvement of drilling and excavation technologies and sampling methods; ii) Estimation of hydrogeological, rock mechanical and geochemical parameters of the undisturbed Opalinus Clay. Upscaling of parameters from laboratory to in situ scale; iii) Geochemistry of porewater and natural gases; evolution of porewater over time scales; iv) Assessment of long-term hydraulic transients associated with erosion and thermal

A low cardiovascular disease risk profile (untreated cholesterol <200 mg/dL, untreated blood pressure <120/<80 mm Hg, never smoking, and no history of diabetes mellitus or myocardial infarction) in middle age is associated with markedly better health outcomes in older age, but few middle-aged adults have this low risk profile. We examined whether adopting a healthy lifestyle throughout young adulthood is associated with the presence of the low cardiovascular disease risk profile in middle age. The Coronary Artery Risk Development in (Young) Adults (CARDIA) study sample consisted of 3154 black and white participants 18 to 30 years of age at year 0 (1985-1986) who attended the year 0, 7, and 20 examinations. Healthy lifestyle factors defined at years 0, 7, and 20 included average body mass index <25 kg/m(2), no or moderate alcohol intake, higher healthy diet score, higher physical activity score, and never smoking. Mean age (25 years) and percentage of women (56%) were comparable across groups defined by number of healthy lifestyle factors. The age-, sex-, and race-adjusted prevalences of low cardiovascular disease risk profile at year 20 were 3.0%, 14.6%, 29.5%, 39.2%, and 60.7% for people with 0 or 1, 2, 3, 4, and 5 healthy lifestyle factors, respectively (P for trend <0.0001). Similar graded relationships were observed for each sex-race group (all P for trend <0.0001). Maintaining a healthy lifestyle throughout young adulthood is strongly associated with a low cardiovascular disease risk profile in middle age. Public health and individual efforts are needed to improve the adoption and maintenance of healthy lifestyles in young adults.

We appreciate Terry and Goff's thoughtful comment in response to our proposed atoll development model. Flank collapse of reef-built slopes likely does affect plan-form atoll morphology in some locations and potentially poses a tsunami hazard to low-lying Pacific islands (Terry and Goff, 2013). However, given the often rapid rates of lagoon infill (> 1 mm/yr; Montaggioni, 2005), such failure events would likely need to be frequent and widespread in order to leave a morphologic imprint on modern western Pacific atoll lagoon depths. Few atoll flank collapse features have been dated but many of the arcuate bight-like structures (ABLS) identified could be inherited from scars incised into the initial volcanic edifice (e.g. Terry and Goff, 2013 and refs. therein) — submarine mass wasting has been extensively documented on young hotspot islands (e.g. Hawaiian Islands: Moore et al., 1989; Reunion: Oehler et al., 2008). Atolls in the Marshall Islands, where our main study site Enewetak Atoll is located, are likely ~ 50–100 million years old (Larson et al., 1995) and dating of adjacent deep-water turbidite aprons in the Nauru Basin (DSDP Site 462; Schlanger and Silva, 1986) suggests that large atoll flank collapse events have been relatively infrequent there since the mid-Miocene (< 11 Ma). In our simple, 1D atoll development model (Toomey et al., 2016a), we included the minimum set of processes (vertical accretion, dissolution, and lagoonal infilling) required to accurately simulate Enewetak's ‘recent’ depositional history (8.5–0 Ma) and explain basic differences in lagoon depth among western Pacific atolls.We agree future development of a model incorporating the wider range of processes impacting connectivity between reef-bound lagoons and the ocean (e.g. Ouillon et al., 2004; Toomey et al., 2016b), including stochastic mass wasting events, will be essential for exploring the plan-form and 3D shapes of atolls. To our knowledge, no quantitative model of long

Lack of Association between Polymorphisms of Hepatic Lipase with Lipid Profile in Young Jordanian Adults

PubMed Central

2014-01-01

The human hepatic lipase (LIPC) gene encodes hepatic lipase, an enzyme involved in lipoprotein metabolism and regulation. Therefore, variants in LIPC gene may influence plasma lipoprotein levels. In this study, the association of LIPC C-514T and G-250A polymorphisms with plasma lipid profiles in 348 young Jordanians was investigated. Genotyping of C-514T and G-250A was performed by polymerase chain reaction and subsequent digestion with DraI and NiaIII restriction enzymes, respectively, while Roche analyzer was used to determine plasma total cholesterol, triglycerides, low-and high-density lipoprotein. The G-250 and C-514 alleles were most abundant in Jordanians with 79 and 80% frequencies, respectively. Additionally, no difference was found in the lipid–lipoprotein profile between the different genotype groups of C-514T or G-250A polymorphisms, even when males and females were examined separately (P > 0.05). In young Jordanian adults, the examined LIPC polymorphisms seem to play a limited role in determining the lipid profile. PMID:25278769

These analyses assess contextual profiles of 612 young adult Ecstasy users, 18–30 years of age, from St. Louis (USA), Miami (USA) and Sydney (Australia). Bivariate analyses revealed different contextual factors influencing Ecstasy use. Friends were the most common sources of Ecstasy at all sites and most used with friends. St. Louis and Miami use mostly occurred in residences, whereas in Sydney use was mostly at clubs, bars or restaurants. Ecstasy consumption at public places and in cars, trains or ferries was significantly higher in Miami (89% and 77%) than in St. Louis (67% and 65%) and Sydney (67% and 61%). At all sites, simultaneous use of LSD/mushroom and nitrous oxide with Ecstasy was common; concurrent amphetamines predominated in Sydney and heroin/opiates in St. Louis Contextual factors influencing Ecstasy use among young adults vary by geographic region. Their inclusion may help tailor effective prevention programs to reduce or ameliorate Ecstasy use. PMID:21094585

Biopolitics, Terri Schiavo, and the sovereign subject of death.

PubMed

Bishop, Jeffrey P

2008-12-01

Humanity does not gradually progress from combat to combat until it arrives at universal reciprocity, where the rule of law finally replaces warfare; humanity installs each of its violences in a system of rules and thus proceeds from domination to domination. (Foucault, 1984, 85) In this essay, I take a note from Michel Foucault regarding the notion of biopolitics. For Foucault, biopolitics has both repressive and constitutive properties. Foucault's claim is that with the rise of modern government, the state became exceedingly concerned about the body politic, the bodies that make up the polis, including the health of those bodies. However, Giorgio Agamben claims that Foucault and all western political philosophy misses the relationship between power and Sovereignty, with disastrous results and totalizing tendencies. I explore the case of Terri Schiavo claiming that the social conservatives have attempted to politicize bare life in its legal maneuverings, but I also show how the social liberals open an uncontrollable space between life and death. Both the left and the right miss the aporia at the heart of western political philosophy, and bioethics is complicit in the totalizing effects of contemporary medicine.

Healthy Lifestyle through Young Adulthood and Presence of Low Cardiovascular Disease Risk Profile in Middle Age: The Coronary Artery Risk Development in (Young) Adults (CARDIA) Study

Background A low cardiovascular disease (CVD) risk profile (untreated cholesterol < 200 mg/dl, untreated blood pressure < 120/<80 mmHg, never smoking, and no history of diabetes and myocardial infarction) in middle age is associated with markedly better health outcomes in older age, but few middle aged adults have this low risk profile. We examined whether adopting a healthy lifestyle throughout young adulthood is associated with presence of the low CVD risk profile in middle age. Methods and Results The CARDIA study sample consisted of 3,154 black and white participants aged 18 to 30 years at Year 0 (Y0, 1985-86) who attended the Year 0, 7 and 20 (Y0, Y7 and Y20) examinations. Healthy lifestyle factors (HLFs) defined at Y0, Y7 and Y20 included: 1) Average BMI < 25 kg/m2; 2) No or moderate alcohol intake; 3) higher healthy diet score; 4) higher physical activity score; and 5) Never smoking. Mean age (25 years) and percentage of women (56%) were comparable across groups defined by number of HLFs. The age-, sex- and race-adjusted prevalences of low CVD risk profile at Y20 were 3.0%, 14.6%, 29.5%, 39.2% and 60.7% for people with 0 or 1, 2, 3, 4, and 5 HLFs, respectively (p-trend <0.0001). Similar graded relationships were observed for each sex-race group (all p-trend<0.0001). Conclusions Maintaining a healthy lifestyle throughout young adulthood is strongly associated with low CVD risk profile in middle age. Public health and individual efforts are needed to improve adoption and maintenance of healthy lifestyles in young adults. PMID:22291127

Young women with acute myocardial infarction (AMI) have higher mortality risk than similarly aged men. An adverse lipid profile is an important risk factor for cardiovascular outcomes after AMI, but little is known about whether young women with AMI have a higher-risk lipid pattern than men. We characterized sex differences in lipid profiles and treatment utilization among young adults with AMI. A total of 2,219 adults with AMI (1,494 women) aged 18-55 years were enrolled from 103 hospitals in the United States (2008-2012). Serum lipids and lipoprotein subclasses were measured 1 month after discharge. More than 90% of adults were discharged on a statin, but less than half received a high-intensity dose and 12% stopped taking treatments by 1 month. For both men and women, the median of low-density lipoprotein (LDL) cholesterol was reduced to <100 mg/dL 1 month after discharge for AMI, but high-density lipoprotein (HDL) cholesterol remained <40 mg/dL. Multivariate regression analyses showed that young women had favorable lipoprotein profiles compared with men: women had higher HDL cholesterol and HDL large particle, but lower total cholesterol-to-HDL cholesterol ratio and LDL small particle. Young women with AMI had slightly favorable lipid and lipoprotein profiles compared with men, suggesting that difference in lipid and lipoprotein may not be a major contributor to sex differences in outcomes after AMI. In both men and women, statin remained inadequately used, and low HDL cholesterol level was a major lipid abnormality. Copyright © 2016 Elsevier Inc. All rights reserved.

Self-harm and suicidal behaviour is most prevalent during adolescence, but little is known about the risk profile of adolescents admitted to hospital for suicidal behaviour. Young people who self-harm are at an increased risk of mortality compared to those who do not self-harm; adolescents admitted to hospital for suicidal behaviour are particularly at risk. The aim of this study was to generate a risk profile of adolescents admitted to hospital with suicidal behaviour. We conducted a 12-month retrospective audit of adolescent admissions to the mental health inpatient unit at a tertiary children's hospital in Melbourne, Australia. Routinely collected data were used to generate a risk profile. We found that 212 of 271 (78.2%) admissions were due to suicidal behaviour. Of these, 107 (51%) adolescents were diagnosed with one or more mental disorders at discharge, most commonly major depressive disorder. Beyond known distal determinants of health risk, the proximal risk profile of these adolescents included factors relating to gender, substance use, prior mental health diagnoses and prior admission to hospital. Poor sleep was also a risk factor, with 159 (75%) reporting a recent history of sleeping problems. The very high proportion of admissions to the mental health inpatient unit due to suicidal behaviour reinforces the importance of finding effective methods of identification of the risk processes underpinning suicidal behaviours to reduce the unnecessary waste of young lives by suicide. © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Segmenting by Risk Perceptions: Predicting Young Adults’ Genetic-Belief Profiles with Health and Opinion-Leader Covariates

PubMed Central

Smith, Rachel A.; Greenberg, Marisa; Parrott, Roxanne L.

2014-01-01

With a growing interest in using genetic information to motivate young adults’ health behaviors, audience segmentation is needed for effective campaign design. Using latent class analysis, this study identifies segments based on young adults’ (N = 327) beliefs about genetic threats to their health and personal efficacy over genetic influences on their health. A four-class model was identified. The model indicators fit the risk perception attitude framework (Rimal & Real, 2003), but the covariates (e.g., current health behaviors) did not. In addition, opinion leader qualities covaried with one profile: those in this profile engaged in fewer preventative behaviors and more dangerous treatment options, and also liked to persuade others, making them a particularly salient group for campaign efforts. The implications for adult-onset disorders, like alpha-1 antitrypsin deficiency are discussed. PMID:24111749

Lipid derangements during early postnatal life may induce stable epigenetic changes and alter metabolic programming. We investigated associations between serum lipid profiles in very young children and DNA methylation of tumor necrosis factor-alpha (TNFα) and leptin (LEP). Secondly, we explored if the maternal serum lipid profile modifies DNA methylation in the child. In 120 healthy children at 17 months of age, DNA methylation of TNFα and LEP was measured in DNA derived from whole blood. Linear mixed models were used to calculate exposure-specific differences and associations. Total cholesterol in children was associated with decreased methylation of TNFα (-5.8%, p = 0.036), and HDL-cholesterol was associated with decreased methylation of both TNFα (-6.9%, p = 0.013) and LEP (-3.4%, p = 0.021). Additional adjustment for gestational age at birth, birth weight, sex, breastfeeding and educational level attenuated the effects, TNFα (-6.1%, p = 0.058) and LEP (-3.1%, p = 0.041). In mothers, HDL-cholesterol only was associated with decreased methylation of TNFα in the child (-8.7%, p = 0.001). Our data support the developmental origin of health and disease hypothesis by showing that total cholesterol and HDL-cholesterol levels in very young children are associated with epigenetic metabolic programming, which may affect their vulnerability for developing cardiovascular diseases in later life.

Muon tomography in the Mont Terri underground rock laboratory

Lesparre, N.; Gibert, D.; Marteau, J.; Carlus, B.; Nussbaum, C.

2012-04-01

The Mont Terri underground rock laboratory (Switzerland) was excavated in a Mesozoic shale formation constituted by Opalinus clay. This impermeable formation presents suitable properties for hosting repository sites of radioactive waste. A muon telescope has been placed in this laboratory in October 2009 to establish the feasibility of the muon tomography and to test the sensor performance in a calm environment, where we are protected from atmospheric noisy particles. However, the presence of radon in the gallery as well as charged particles issued from the decay of gamma rays may create a background noise. This noise shift and smooths the signal inducing an under estimation of the rock density. The uncorrelated background has been measured by placing the planes of detection in anti-coincidence. This estimation is preponderant and has to be combined to the theoretical feasibility evaluation to determine the best experimental set-up to observe muon flux fluctuations due to density variations. The muon densitometry experience is here exposed with the estimation of its feasibility. The data acquired from different locations inside the underground laboratory are presented. They are compared to two models representing the layer above the laboratory corresponding to a minimum and a maximum muon flux expectation depending on the values of the rock density.

Consumption of pasteurized human lysozyme transgenic goats’ milk alters serum metabolite profile in young pigs

PubMed Central

Brundige, Dottie R.; Maga, Elizabeth A.; Klasing, Kirk C.

2009-01-01

Nutrition, bacterial composition of the gastrointestinal tract, and general health status can all influence the metabolic profile of an organism. We previously demonstrated that feeding pasteurized transgenic goats’ milk expressing human lysozyme (hLZ) can positively impact intestinal morphology and modulate intestinal microbiota composition in young pigs. The objective of this study was to further examine the effect of consuming hLZ-containing milk on young pigs by profiling serum metabolites. Pigs were placed into two groups and fed a diet of solid food and either control (non-transgenic) goats’ milk or milk from hLZ-transgenic goats for 6 weeks. Serum samples were collected at the end of the feeding period and global metabolite profiling was performed. For a total of 225 metabolites (160 known, 65 unknown) semi-quantitative data was obtained. Levels of 18 known and 4 unknown metabolites differed significantly between the two groups with the direction of change in 13 of the 18 known metabolites being almost entirely congruent with improved health status, particularly in terms of the gastrointestinal tract health and immune response, with the effects of the other five being neutral or unknown. These results further support our hypothesis that consumption of hLZ-containing milk is beneficial to health. PMID:19847666

Young Black gay/bisexual men (YBGBM) are affected by contextual stressors-namely syndemic conditions and minority stress-that threaten their health and well-being. Resilience is a process through which YBGBM achieve positive psychosocial outcomes in the face of adverse conditions. Self-efficacy, hardiness and adaptive coping, and social support may be important resilience factors for YBGBM. This study explores different profiles of these resilience factors in 228 YBGBM in New York City and compares profiles on psychological distress, mental health, and other psychosocial factors. Four profiles of resilience were identified: (a) Low self-efficacy and hardiness/adaptive coping (23.5%); (b) Low peer and parental support (21.2%); (c) High peer support, low father support (34.5%); and (d) High father and mother support, self-efficacy, and hardiness/adaptive coping (20.8%). YBGBM in profile 1 scored markedly higher on distress (d = .74) and lower on mental health functioning (d = .93) compared to men in the other profiles. Results suggest that self-efficacy and hardiness/adaptive coping may play a more important role in protecting YBGBM from risks compared to social support and should be targeted in interventions. The findings show that resilience is a multidimensional construct and support the notion that there are different patterns of resilience among YBGBM. © Society for Community Research and Action 2016.

Profile of young people attending alcohol and other drug treatment services in Aotearoa, New Zealand: clinical file search.

The aim of the present study was to provide a profile of young people attending alcohol and other drug (AOD) treatment services in Aotearoa, New Zealand. Data were gathered from a clinical file search of 184 randomly selected young people aged 13-19 years who had attended one of eight youth AOD treatment services in New Zealand during 2003 or 2004. These services represented eight of the 11 youth-specific AOD services available to youth in New Zealand. Young people who attend youth-specific AOD services in New Zealand present with a range of complex needs including substance use and mental health issues, criminality, family conflict and disengagement from school. A total of 62.0% were male, 56.4% had criminal convictions, 40.6% had spent some time in Child, Youth and Family Services care and 53.8% were reported to have a coexisting substance use and mental health disorder. Low rates of reporting of substance use and mental health diagnoses in treatment files suggest that substance use and mental health disorders among this population are likely to be higher than those reported. This paper provides a unique profile of young people attending youth-specific AOD treatments in New Zealand. Such information is useful in informing treatment planning and funding and ensuring that service development occurs to specifically meet the complex needs of this patient group.

Tailoring in risk communication by linking risk profiles and communication preferences: The case of speeding of young car drivers.

PubMed

Geber, Sarah; Baumann, Eva; Klimmt, Christoph

2016-12-01

Speeding is one of the most relevant risk behaviors for serious and fatal accidents, particularly among young drivers. This study presents a tailoring strategy for anti-speeding communication. By referring to their motivational dispositions toward speeding derived from motivational models of health behavior, young car drivers were segmented into different risk groups. In order to ensure that risk communication efforts would actually be capable to target these groups, the linkage between the risk profiles and communication preferences were explored. The study was conducted on the basis of survey data of 1168 German car drivers aged between 17 and 24 years. The data reveal four types of risk drivers significantly differing in their motivational profiles. Moreover, the findings show significant differences in communication habits and media use between these risk groups. By linking the risk profiles and communication preferences, implications for tailoring strategies of road safety communication campaigns are derived. Promising segmentation and targeting strategies are discussed also beyond the current case of anti-speeding campaigns. Copyright © 2015 Elsevier Ltd. All rights reserved.

One of the most severe complications of acute respiratory infections in young children is acute stenotic laryngotracheitis (croup). The relationship between cytokine blood levels and symptoms of croup, croup severity, disease sequel, despite numerous studies is still unclear. Cytokine profile in young children with acute stenotic laryngotracheitis investigation. 112 children aged 12 min. - 36 mon. with acute stenotic laryngotracheitis which were treated at the Lviv Regional Infectious Diseases Hospital were kept under observation. Croup symptoms, levels of interleukins (IL1, IL4, IL6, IL10, IL17) in serum, DNA and RNA viruses in respiratory nasal mucus were studied; Chan croup severity was used. In the pathogenesis of croup has an important role the imbalance between inflammatory (IL1, IL6) and anti-inflammatory (IL4, IL10, IL17) cytokines, which does not reduce the intensity of inflammatory reactions and its lead to local swelling, muscle spasm, excessive production of mucus in the place of viral replication. The levels of inflammatory and anti-inflammatory cytokines in the blood serum of children with croup were significantly higher than in patients with acute laryngitis. In patients with recurrent croup, unlike patients with the first case of croup does we don't see a significant correlation between the concentrations of inflammatory and anti-inflammatory cytokine levels Conclusions: The significantly higher levels of cytokines in children with croup compared with the group of patients with acute laryngitis were found, imbalance between anti-inflammatory (IL1, IL6) cytokine levels and inflammatory (IL4, IL10, IL17) cytokine levels in children who developed recurrent croup.

Nonalcoholic fatty liver is associated with obesity‐related metabolic disturbances, but little is known about the metabolic perturbations preceding fatty liver disease. We performed comprehensive metabolic profiling to assess how circulating metabolites, such as lipoprotein lipids, fatty acids, amino acids, and glycolysis‐related metabolites, reflect the presence of and future risk for fatty liver in young adults. Sixty‐eight lipids and metabolites were quantified by nuclear magnetic resonance metabolomics in the population‐based Young Finns Study from serum collected in 2001 (n = 1,575), 2007 (n = 1,509), and 2011 (n = 2,002). Fatty liver was diagnosed by ultrasound in 2011 when participants were aged 34‐49 years (19% prevalence). Cross‐sectional associations as well as 4‐year and 10‐year risks for fatty liver were assessed by logistic regression. Metabolites across multiple pathways were strongly associated with the presence of fatty liver (P < 0.0007 for 60 measures in age‐adjusted and sex‐adjusted cross‐sectional analyses). The strongest direct associations were observed for extremely large very‐low‐density lipoprotein triglycerides (odds ratio [OR] = 4.86 per 1 standard deviation, 95% confidence interval 3.48‐6.78), other very‐low‐density lipoprotein measures, and branched‐chain amino acids (e.g., leucine OR = 2.94, 2.51‐3.44). Strong inverse associations were observed for high‐density lipoprotein measures, e.g., high‐density lipoprotein size (OR = 0.36, 0.30‐0.42) and several fatty acids including omega‐6 (OR = 0.37, 0.32‐0.42). The metabolic associations were attenuated but remained significant after adjusting for waist, physical activity, alcohol consumption, and smoking (P < 0.0007). Similar aberrations in the metabolic profile were observed already 10 years before fatty liver diagnosis. Conclusion: Circulating lipids, fatty acids, and amino acids reflect fatty liver independently of routine metabolic risk

Hydrodynamic profile of young swimmers: changes over a competitive season.

2015-04-01

The aim of this study was to analyze the changes in the hydrodynamic profile of young swimmers over a competitive season and to compare the variations according to a well-designed training periodization. Twenty-five swimmers (13 boys and 12 girls) were evaluated in (a) October (M1); (b) March (M2); and (c) June (M3). Inertial and anthropometrical measures included body mass, swimmer's added water mass, height, and trunk transverse surface area. Swimming efficiency was estimated by the speed fluctuation, stroke index, and approximate entropy. Active drag was estimated with the velocity perturbation method and the passive drag with the gliding decay method. Hydrodynamic dimensionless numbers (Froude and Reynolds numbers) and hull velocity (i.e., speed at Froude number = 0.42) were also calculated. No variable presented a significant gender effect. Anthropometrics and inertial parameters plus dimensionless numbers increased over time. Swimming efficiency improved between M1 and M3. There was a trend for both passive and active drag increase from M1 to M2, but being lower at M3 than at M1. Intra-individual changes between evaluation moments suggest high between- and within-subject variations. Therefore, hydrodynamic changes over a season occur in a non-linear fashion way, where the interplay between growth and training periodization explain the unique path flow selected by each young swimmer. © 2014 John Wiley & Sons A/S.

Wong, Rebecca S. K.; Thung, Jin Seng; Pieter, Willy

2006-01-01

In an attempt to test the conceptual model by Lane and Terry, the purposes of this study were 1) to assess mood states in non-depressed and depressed young karate athletes; 2) to assess mood states in relation to performance in young karate athletes. The participants were recruited from the 2004 Malaysian Games (72 males, 19.20 ± 1.16 years; 37 females, 18.78 ± 0.88 years). The athletes were divided into winners (medalists) and losers. The Brunel Mood Scale (BRUMS) was administered prior to the start of competition. MANOVA was employed to treat the data, while Pearson correlations were calculated for mood states in each depressed mood group and by gender. In terms of non-depressed and depressed mood, tension in the females was higher in the depressed group (5.61 ± 3.02 vs. 3.11 ± 1.90, p = 0.026, eta2 = 0.133), as was fatigue (3.64 ± 2.61 vs. 0.89 ± 1.69, p = 0.006, eta2 = 0.199). Tension in the males was higher in the depressed group (4.41 ± 2.52 vs. 1.50 ± 1.55, p < 0.001, eta2 = 0.215), as was anger (1.43 ± 1.88 vs. 0.25 ± 1.00, p = 0.019, eta2 = 0.076). The highest associations among mood subscales were between anger and depression (r = 0.57), and between depression and fatigue ( r = 0.55) in depressed males. The female winning karateka scored higher on anger (3.08 ± 2.96 vs. 1.29 ± 2.24, p = 0.046, eta2 = 0.109). The highest correlations between mood dimensions in depressed females were between depression and anger (r = 0.85) and between depression and confusion (r = 0.85). Contrary to previous research on the influence of depression on anger, only the female winners scored higher on anger. Several negative mood dimensions were higher in both male and female depressed groups, lending some support to the conceptual model advanced by Lane and Terry. Key Points To date, there is no information about the relationship between mood and martial arts performance in Malaysian athletes. There might be cultural differences in the way Malaysian athletes

Sedentary behavior is associated with poor well-being in youth with adverse trajectories spanning to adulthood. Still, its determinants are poorly known. Our aim was to profile sedentary and non-sedentary young men and to clarify their differences in a population-based setting. A total of 616 men (mean age 17.9, SD 0.6) attending compulsory conscription for military service completed a questionnaire on health, health behavior, socioeconomic situation and media use. They underwent a physical (body composition, muscle and aerobic fitness) and medical examination. Profiles were formed by principal component analysis (PCA). A total of 30.1 % men were sedentary (daily leisure-time sitting ≥5 h) and 28.9 % non-sedentary (sitting ≤2 h). The sedentary men had more body fat, more depressive symptoms, but lower fitness and life satisfaction than non-sedentary men. However, according to PCA, profiles of unhealthy eating, life-dissatisfaction, and gaming were detected both among sedentary and non-sedentary men, as well as high self-rated PA and motives to exercise. Determinants of sedentary and non-sedentary lifestyles were multiple and partially overlapping. Recognizing individual patterns and underlying factors of the sedentary lifestyle is essential for tailored health promotion and interventions.

Recent research has emphasized the need to better discriminate asthma phenotypes and consider underlying mechanistic endotypes in epidemiologic and clinical studies. Although allergic asthma and nonallergic asthma are frequently combined into 1 disease category in observational research and clinical trials, few studies have investigated the extent to which these 2 separate phenotypes are associated with distinct cytokine immunologic profiles in a representative young adult population. To investigate the cytokine production-based endotypes underlying the clinical phenotypes of allergic and nonallergic asthma in a population-based birth cohort evaluated as young adults. Participants included 18- to 21-year-old members (n = 540) of a suburban Detroit birth cohort study, the Childhood Allergy Study. Phorbol myristate acetate-stimulated whole blood interleukin (IL)-4, IL-5, IL-10, IL-12, IL-13, IL-17A, IL-17F, IL-22, and interferon-γ secretory responses were analyzed for associations comparing participants with allergic vs nonallergic asthma phenotypes with those without asthma. T-helper cell type (TH) 2-polarized responses, measured as higher mean IL-5 and IL-13 secretions and lower ratios of interferon-γ and IL-12 to 3 TH2 cytokines (IL-4, IL-5, or IL-13), were observed only in participants with allergic asthma. Nonallergic asthma was associated with TH1-polarized responses, including higher adjusted interferon-γ secretion compared with participants with allergic asthma and, surprisingly, those without asthma (odds ratio 2.5, confidence interval 1.2-5.1, P < .01). As expected, young adults with a history of an allergic asthma phenotype exhibited a TH2-polarized cytokine response after polyclonal stimulation. However, TH1 polarization was observed in patients with a history of nonallergic asthma. Allergic and nonallergic asthma are associated with etiologically distinct immune endotypes, underscoring the importance of discriminating these endotypes in research

Nutritional epidemiology is increasingly shifting its focus from studying single nutrients to the exploration of the whole diet utilizing dietary pattern analysis. We analyzed associations between habitual diet (including macronutrients, dietary patterns, biomarker of fish intake) and lipoprotein particle subclass profile in young adults. Complete dietary data (food-frequency questionnaire) and lipoprotein subclass profile (via nuclear magnetic resonance spectroscopy) were available for 663 subjects from the population-based FinnTwin12 study (57% women, age: 21-25 y). The serum docosahexaenoic to total fatty acid ratio was used as a biomarker of habitual fish consumption. Factor analysis identified 5 dietary patterns: "Fruit and vegetables", "Meat", "Sweets and desserts", "Junk food" and "Fish". After adjustment for sex, age, body mass index, waist circumference, physical activity, smoking status and alcohol intake, the "Junk food" pattern was positively related to serum triglycerides (r = 0.12, P = 0.002), a shift in the subclass distribution of VLDL toward larger particles (r = 0.12 for VLDL size, P < 0.001) and LDL toward smaller particles (r = -0.15 for LDL size, P < 0.001). In addition, higher scores on this pattern were positively correlated with concentrations of small, dense HDL (r = 0.16, P < 0.001). Habitual fish intake associated negatively with VLDL particle diameter ("Fish" pattern and biomarker) and positively with HDL particle diameter (biomarker). Our results suggest that in young adults, higher habitual fish consumption is related to favorable subclass distributions of VLDL and HDL, while junk food intake is associated with unfavorable alterations in the distribution of all lipoprotein subclasses independent of adiposity and other lifestyle factors.

Comorbid internalizing mental disorders in alcohol use disorders (AUD) can be understood as putative independent risk factors for AUD or as expressions of underlying shared psychopathology vulnerabilities. However, it remains unclear whether: 1) specific latent internalizing psychopathology risk-profiles predict AUD-incidence and 2) specific latent internalizing comorbidity-profiles in AUD predict AUD-stability. To investigate baseline latent internalizing psychopathology risk profiles as predictors of subsequent AUD-incidence and -stability in adolescents and young adults. Data from the prospective-longitudinal EDSP study (baseline age 14-24 years) were used. The study-design included up to three follow-up assessments in up to ten years. DSM-IV mental disorders were assessed with the DIA-X/M-CIDI. To investigate risk-profiles and their associations with AUD-outcomes, latent class analysis with auxiliary outcome variables was applied. AUD-incidence: a 4-class model (N=1683) was identified (classes: normative-male [45.9%], normative-female [44.2%], internalizing [5.3%], nicotine dependence [4.5%]). Compared to the normative-female class, all other classes were associated with a higher risk of subsequent incident alcohol dependence (p<0.05). AUD-stability: a 3-class model (N=1940) was identified with only one class (11.6%) with high probabilities for baseline AUD. This class was further characterized by elevated substance use disorder (SUD) probabilities and predicted any subsequent AUD (OR 8.5, 95% CI 5.4-13.3). An internalizing vulnerability may constitute a pathway to AUD incidence in adolescence and young adulthood. In contrast, no indication for a role of internalizing comorbidity profiles in AUD-stability was found, which may indicate a limited importance of such profiles - in contrast to SUD-related profiles - in AUD stability.

The present study tested and extended Lane and Terry (2000) conceptual model of mood-performance relationships using a large dataset from an online experiment. Methodological and theoretical advances included testing a more balanced model of pleasant and unpleasant emotions, and evaluating relationships among emotion regulation traits, states and beliefs, psychological skills use, perceptions of performance, mental preparation, and effort exerted during competition. Participants ( N = 73,588) completed measures of trait emotion regulation, emotion regulation beliefs, regulation efficacy, use of psychological skills, and rated their anger, anxiety, dejection, excitement, energy, and happiness before completing a competitive concentration task. Post-competition, participants completed measures of effort exerted, beliefs about the quality of mental preparation, and subjective performance. Results showed that dejection associated with worse performance with the no-dejection group performing 3.2% better. Dejection associated with higher anxiety and anger scores and lower energy, excitement, and happiness scores. The proposed moderating effect of dejection was supported for the anxiety-performance relationship but not the anger-performance relationship. In the no-dejection group, participants who reported moderate or high anxiety outperformed those reporting low anxiety by about 1.6%. Overall, results showed partial support for Lane and Terry's model. In terms of extending the model, results showed dejection associated with greater use of suppression, less frequent use of re-appraisal and psychological skills, lower emotion regulation beliefs, and lower emotion regulation efficacy. Further, dejection associated with greater effort during performance, beliefs that pre-competition emotions did not assist goal achievement, and low subjective performance. Future research is required to investigate the role of intense emotions in emotion regulation and performance.

Applying a person-centered approach, the primary aim of this study was to examine what profiles of schoolwork engagement and burnout (i.e., exhaustion, cynicism, inadequacy) can be identified in high school (N = 979) and among the same participants in young adulthood (ages ranging from 17 to 25). We also examined gender differences, group differences in academic and socioemotional functioning and long-term educational outcomes, and temporal stability in the group memberships. Latent profile analysis identified 4 groups of students in high school. Both engaged (44%) and engaged-exhausted (28%) students were engaged and doing well in school, although engaged-exhausted students were more stressed and preoccupied with possible failures. Cynical (14%) and burned-out (14%) students were less engaged, valued school less, and had lower academic achievement. Cynical students, however, were less stressed, exhausted, and depressed than burned-out students. Six years later, engaged students were more likely than predicted by chance to attend university. In young adulthood, 4 similar groups were identified. Configural frequency analysis indicated that it was typical for engaged students to stay in the engaged group and for engaged-exhausted students to move into a more disengaged group. The results on broadband stability from adolescence to young adulthood showed that 60% of the youth manifested stable engaged and 7% stable disengaged patterns, whereas 16% displayed emergent engagement and 17% emergent disengagement patterns. Overall, the findings demonstrate that adolescence is not a uniform time for either school engagement and well-being or disengagement and distress.

Laterality is a key aspect of the analysis of basic and specific motor skills. It is relevant to sports because it involves motor laterality profiles beyond left-right preference and spatial orientation of the body. The aim of this study was to obtain the laterality profiles of young athletes, taking into account the synergies between the support and precision functions of limbs and body parts in the performance of complex motor skills. We applied two instruments: (a) MOTORLAT, a motor laterality inventory comprising 30 items of basic, specific, and combined motor skills, and (b) the Precision and Agility Tapping over Hoops (PATHoops) task, in which participants had to perform a path by stepping in each of 14 hoops arranged on the floor, allowing the observation of their feet, left-right preference and spatial orientation. A total of 96 young athletes performed the PATHoops task and the 30 MOTORLAT items, allowing us to obtain data about limb dominance and spatial orientation of the body in the performance of complex motor skills. Laterality profiles were obtained by means of a cluster analysis and a correlational analysis and a contingency analysis were applied between the motor skills and spatial orientation actions performed. The results obtained using MOTORLAT show that the combined motor skills criterion (for example, turning while jumping) differentiates athletes' uses of laterality, showing a clear tendency toward mixed laterality profiles in the performance of complex movements. In the PATHoops task, the best spatial orientation strategy was “same way” (same foot and spatial wing) followed by “opposite way” (opposite foot and spatial wing), in keeping with the research assumption that actions unfolding in a horizontal direction in front of an observer's eyes are common in a variety of sports.

Numerous data suggest that aerobic-type exercise improves lipoprotein-lipid profiles, cardiorespiratory fitness and body composition in young women. The aim of this study was to evaluate the biological response to high-low impact aerobic fitness among young women. Thirty-four young women aged 22 (19-24) years were divided into three groups: underweight (N=10), normal weight (N=12) and overweight (N=12). Aerobic capacity, anthropometry and body composition together with complete blood count and lipid profile were determined before and after completion of a 12-week-long training period. The training programme caused a significant decrease in weight (by 4.3 kg, P=0.003), body mass index (by 1.3 kg/m2, P=0.003), free fat mass (by 2.1 kg, P=0.002), total body water (by 0.4 kg, P=0.036), percentage of fat (by 3 percent points, P=0.002), all analyzed skinfolds thicknesses, as well as the lipid profile in overweight group, and no changes in normal weight group. Significant changes in weight (by 4.2 kg, P=0.005), body mass index (by 0.9 kg/m2, P=0.005), crus skinfold thickness (by 3.3 mm, P=0.028), and in maximum oxygen uptake (by 2.49 mL/kg/min; P=0.047) were observed among underweight women. No change in total blood count was observed in all groups. Twelve-week-long fitness training programme of two alternating styles (low and high impact) has a beneficial effect on overweight young women.

Serum lipid profiles of 76 men of young age (17-21years) were investigated using thin layer chromatography and determination of somatotypes was realized using the scheme of V.P. Chtetsov et al. (1978). The investigation was conducted on an empty stomach and after one hour after food loads (test meal with energy value of 419 kcal, content of proteins - 17,9 g, fats - 11,9 g, carbohydrates - 60,1 g). Regularities inherent to certain somatotypes were revealed. In young men with the abdominal somatotype (with the most pronounced fat component), changes evidencing membranes rigidity growth were revealed: cholesterol esterification processes inhibition and increase of sphingomyelin after meal (p = 0.001). In young men with muscular somatotype the highest level of phosphatidylcholine and the lowest level of easily-oxidized phospholipid fractions in comparison to other somatotypes [thoracic (p = 0.044), abdominal (p = 0.037) and undetermined (p = 0.021)] were registered. General rule is lowering of the free fatty acids levels after meal in comparison with the indices on the empty stomach for all somatotypes: thoracic (p = 0.0001), muscular (p = 0.012), abdominal (p = 0.041) and undetermined (p = 000018). Definiteness of the effect of lowering of free fatty acids levels after meal for all somatotypes could evidence the importance Of this process for maintaining the homeostatic body constants.

Context. We still do not understand which physical mechanisms are responsible for the transport of angular momentum inside stars. The recent detection of mixed modes that contain the clear signature of rotation in the spectra of Kepler subgiants and red giants gives us the opportunity to make progress on this question. Aims: Our aim is to probe the radial dependence of the rotation profiles for a sample of Kepler targets. For this purpose, subgiants and early red giants are particularly interesting targets because their rotational splittings are more sensitive to the rotation outside the deeper core than is the case for their more evolved counterparts. Methods: We first extracted the rotational splittings and frequencies of the modes for six young Kepler red giants. We then performed a seismic modeling of these stars using the evolutionary codes Cesam2k and astec. By using the observed splittings and the rotational kernels of the optimal models, we inverted the internal rotation profiles of the six stars. Results: We obtain estimates of the core rotation rates for these stars, and upper limits to the rotation in their convective envelope. We show that the rotation contrast between the core and the envelope increases during the subgiant branch. Our results also suggest that the core of subgiants spins up with time, while their envelope spins down. For two of the stars, we show that a discontinuous rotation profile with a deep discontinuity reproduces the observed splittings significantly better than a smooth rotation profile. Interestingly, the depths that are found to be most probable for the discontinuities roughly coincide with the location of the H-burning shell, which separates the layers that contract from those that expand. Conclusions: We characterized the differential rotation pattern of six young giants with a range of metallicities, and with both radiative and convective cores on the main sequence. This will bring observational constraints to the

Although children with ASD show significant variation in language skills, research on what type(s) of language profiles they demonstrate has been limited. Using growth-curve analyses, we investigated how different groups of young children with ASD show increases in the size of their lexicon, morpho-syntactic production as measured by Brown’s 14 grammatical morphemes, and wh-question complexity, compared to TD children, across six time points. Children with ASD who had higher verbal skills were comparable to TD children on most language measures, whereas the children with ASD who had low verbal skills had flatter trajectories in most language measures. Thus, two distinct language profiles emerged for children with ASD. PMID:23719855

Physiological transient imbalance typical of adolescence needs to be distinguished from hyperandrogenism-related dysfunction. The accurate determination of circulating androgens is the best indicator of hyperandrogenism. However, reliable reference intervals for adolescent and young women are not available. The aim of the study was to define androgen reference intervals in young women and to analyze the impact of the menstrual phase and ovulation efficiency over the androgen profile as assessed by reliable liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique. Female high school students aged 16-19 years were included in the study. The study was performed on reference subjects properly selected among an unbiased population. Normal-weight, drug and disease free, eumenorrheic females with no signs of hyperandrogenism were included. The steroid hormone profile was determined by a validated in-house LC-MS/MS method. A statistical estimation of overall and menstrual phase-specific reference intervals was performed. A subgroup of anovulatory females was identified based on progesterone circulating levels. The impact of ovulation efficiency over hormonal profile was analyzed. A total of 159 females satisfied healthy criteria. Androgen levels did not vary according to menstrual phase, but a significantly higher upper reference limit was found for T in the luteal phase compared to the follicular phase. Higher T and androstenedione levels were observed in anovulatory compared to ovulatory females, paralleled by higher LH and FSH and lower 17-hydroxyprogesterone and 17β-estradiol levels. This is the first study providing LC-MS/MS-based, menstrual phase-specific reference intervals for the circulating androgen profile in young females. We identified a subgroup of anovulatory healthy females characterized by androgen imbalance.

Resistance to insulin actions is contributing to many metabolic disturbances. Such factors as age, sex, nutrition, body fat, and physical activity determine body insulin resistance. Present study attempted to asses insulin resistance and its metabolic effects with respect to energy intake in young, lean, and active men. A total of 87 men aged 18-23 participated in the study. Plasma levels of glucose, insulin, lipoproteins, cortisol, and TSH were determined. Insulin resistance was expressed as Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) and calculated using homeostatic model. The median value of HOMA-IR (1.344) was used to divide subjects into two groups. Men did not differ in anthropometric parameters, daily physical activity, and plasma TSH and cortisol levels. However, in men with higher HOMA-IR significantly lower daily energy intake was observed concomitantly with higher TG, TC, and HDL-C concentrations in plasma versus their counterparts with lower HOMA-IR. Exclusively in subjects with higher HOMA-IR significant and positive correlation was noted between HOMA-IR and TC and LDL-C. We concluded that despite a normal body weight and physical activity, a subset of young men displayed unfavorable changes in insulin sensitivity and lipid profile, probably due to insufficient energy intake.

The aim of this study was to examine the influence of hormonal status, anthropometric profile, sexual maturity level, and physical performance on the technical abilities of 40 young male soccer players during small-sided games (SSGs). Anthropometric profiling, saliva sampling, sexual maturity assessment (Tanner scale), and physical performance tests (Yo-Yo and vertical jumps) were conducted two weeks prior to the SSGs. Salivary testosterone was determined by the enzyme-linked immunosorbent assay method. Technical performance was determined by the frequency of actions during SSGs. Principal component analyses identified four technical actions of importance: total number of passes, effectiveness, goal attempts, and total tackles. A multivariate canonical correlation analysis was then employed to verify the prediction of a multiple dependent variables set (composed of four technical actions) from an independent set of variables, composed of testosterone concentration, stage of pubic hair and genitalia development, vertical jumps and Yo-Yo performance. A moderate-to-large relationship between the technical performance set and the independent set was observed. The canonical correlation was 0.75 with a canonical R 2 of 0.45. The highest structure coefficient in the technical performance set was observed for tackles (0.77), while testosterone presented the highest structure coefficient (0.75) for the variables of the independent set. The current data suggest that the selected independent set of variables might be useful in predicting SSG performance in young soccer players. Coaches should be aware that physical development plays a key role in technical performance to avoid decision-making mistakes during the selection of young players.

Anisotropy of electrical conductivity of the excavation damaged zone in the Mont Terri Underground Rock Laboratory

2010-04-01

Electrical resistivity measurements were performed to characterize the anisotropy of electrical resistivity of the excavation damaged zone (EDZ) at the end-face of a gallery in the Opalinus clay of the Mont Terri Underground Rock Laboratory (URL). The data were acquired with a combination of square arrays in 18 zones on the gallery's face and in two series of four boreholes perpendicular to the face. Each data set is independently inverted using simulated annealing to recover the resistivity tensor. Both the stability and the non-uniqueness of the inverse problem are discussed with synthetic examples. The inversion of the data shows that the face is split in two domains separated by a tectonic fracture, with different resistivity values but with a common orientation. The direction of the maximum resistivity is found perpendicular to the bedding plane, and the direction of minimum resistivity is contained in the face's plane. These results show that the geo-electrical structure of the EDZ is controlled by a combination of effects due to tectonics, stratigraphy, and recent fracturing produced by the excavation of the gallery.

Metabolic profiling in Maturity-onset diabetes of the young (MODY) and young onset type 2 diabetes fails to detect robust urinary biomarkers.

It is important to identify patients with Maturity-onset diabetes of the young (MODY) as a molecular diagnosis determines both treatment and prognosis. Genetic testing is currently expensive and many patients are therefore not assessed and are misclassified as having either type 1 or type 2 diabetes. Biomarkers could facilitate the prioritisation of patients for genetic testing. We hypothesised that patients with different underlying genetic aetiologies for their diabetes could have distinct metabolic profiles which may uncover novel biomarkers. The aim of this study was to perform metabolic profiling in urine from patients with MODY due to mutations in the genes encoding glucokinase (GCK) or hepatocyte nuclear factor 1 alpha (HNF1A), type 2 diabetes (T2D) and normoglycaemic control subjects. Urinary metabolic profiling by Nuclear Magnetic Resonance (NMR) and ultra performance liquid chromatography hyphenated to Q-TOF mass spectrometry (UPLC-MS) was performed in a Discovery set of subjects with HNF1A-MODY (n = 14), GCK-MODY (n = 17), T2D (n = 14) and normoglycaemic controls (n = 34). Data were used to build a valid partial least squares discriminate analysis (PLS-DA) model where HNF1A-MODY subjects could be separated from the other diabetes subtypes. No single metabolite contributed significantly to the separation of the patient groups. However, betaine, valine, glycine and glucose were elevated in the urine of HNF1A-MODY subjects compared to the other subgroups. Direct measurements of urinary amino acids and betaine in an extended dataset did not support differences between patients groups. Elevated urinary glucose in HNF1A-MODY is consistent with the previously reported low renal threshold for glucose in this genetic subtype. In conclusion, we report the first metabolic profiling study in monogenic diabetes and show that, despite the distinct biochemical pathways affected, there are unlikely to be robust urinary biomarkers which distinguish monogenic subtypes

Does Drinking Location Matter? Profiles of Risky Single-Occasion Drinking by Location and Alcohol-Related Harm among Young Men.

In adolescents and young adults, acute consequences like injuries account for a substantial proportion of alcohol-related harm, especially in risky single-occasion (RSO) drinkers. The primary aim of the study was to characterize different drinking profiles in RSO drinkers according to drinking locations and their relationship to negative, alcohol-related consequences. The sample consisted of 2746 young men from the Cohort Study on Substance Use Risk Factors who had reported drinking six or more drinks on a single-occasion at least monthly over the preceding 12 months. Principal component analysis on the frequency and amount of drinking at 11 different locations was conducted, and 2 distinguishable components emerged: a non-party-dimension (loading high on theater/cinema, sport clubs, other clubs/societies, restaurants, and sport events) and a party-dimension (loading high on someone else's home, pubs/bars, discos/nightclubs, outdoor public places, special events, and home). Differential impacts of drinking location profiles were observed on severe negative alcohol-related consequences (SAC). Relative to those classified as low or intermediate in both dimensions, no significant difference experiencing SAC was found among those who were classified as high in the non-party-dimension only. However, those who were classified as high in the party-dimension alone or in both dimensions were more likely to experience SAC. These differential effects remained after adjusting for alcohol consumption (volume and risky single-occasion drinking), personality traits, and peer-influence [adjusted OR = 0.83 (0.68-1.02), 1.57 (1.27-1.96), and 1.72 (1.23-2.41), respectively], indicating independent effects of drinking location on SAC. The inclusion of sociodemographic factors did not alter this association. The fact that this cluster of party-dimension locations seems to predispose young men to experiencing SAC has important implications for alcohol control policies.

To determine exposure to media coverage of Terri Schiavo (TS) and its impact on ACP. Descriptive study of 117 English/Spanish-speakers, aged >or=50 years (mean 61 years) from a county hospital, interviewed six months after enrollment into an advance directive study. We assessed whether participants had heard of TS and subject characteristics associated with exposure. We also asked whether, because of TS, subjects engaged in ACP. Ninety-two percent reported hearing of TS. Participants with adequate literacy were more likely than those with limited literacy to report hearing of TS (100% vs. 79%, P < .001), as were participants with >or= a high school vs. < high school education (97% vs. 82%, P = .004), and English vs. Spanish-speakers (96% vs. 85%, P = .04). Because of TS, many reported clarifying their own goals of care (61%), talking to their family/friends about ACP (66%), and wanting to complete an advance directive (37%). Most diverse older adults had heard of TS and reported that her story activated them to engage in ACP. Media stories may provide a powerful opportunity to engage patients in ACP and develop public health campaigns.

While disturbances of the sleep-wake cycle are common in people with affective disorders, the characteristics of these disturbances differ greatly between individuals. This heterogeneity is likely to reflect multiple underlying pathophysiologies, with different perturbations in circadian systems contributing to the variation in sleep-wake cycle disturbances. Such disturbances may be particularly relevant in adolescents and young adults with affective disorders as circadian rhythms undergo considerable change during this key developmental period. This study aimed to identify profiles of sleep-wake disturbance in young people with affective disorders and investigate associations with biological circadian rhythms. Fifty young people with affective disorders and 19 control participants (aged 16-31 years) underwent actigraphy monitoring for approximately two weeks to derive sleep-wake cycle parameters, and completed an in-laboratory assessment including evening dim-light saliva collection for melatonin assay and overnight continuous core body temperature measurement. Cluster analysis based on sleep-wake cycle parameters identified three distinct patient groups, characterised by 'delayed sleep-wake', 'disrupted sleep', and 'long sleep' respectively. The 'delayed sleep-wake' group had both delayed melatonin onset and core temperature nadir; whereas the other two cluster groups did not differ from controls on these circadian markers. The three groups did not differ on clinical characteristics. These results provide evidence that only some types of sleep-wake disturbance in young people with affective disorders are associated with fundamental circadian perturbations. Consequently, interventions targeting endogenous circadian rhythms to promote a phase shift may be particularly relevant in youth with affective disorders presenting with delayed sleep-wake cycles.

Traditionally, physical and anthropometrical profiles of the most successful kayak athletes have been identified in male kayakers. This study attempted to identify the differences in morphology and fitness level of two performance-based groups of young elite female paddlers. Eighty-six female kayakers, aged 13.62 ± 0.57 years (mean ± SD) were allocated in two groups (Top-10 and Rest) depending on their ranking in the three Olympic distances (200, 500 and 1000 meters). All subjects underwent a battery of anthropometrical (heights, weight, girths and sum of skinfolds), physical fitness (overhead medicine ball throw, countermovement jump, sit-and-reach test and 20-m multistage shuttle run test) and specific performance assessments (200, 500 and 1000 meters). Best paddlers presented significantly greater anthropometrical values in muscle mass percentage, maturity status and chronological age (p < 0.05) whereas physical fitness comparison only revealed significant differences in countermovement jump (p < 0.05). Furthermore, aerobic power and muscle mass percentage appear to be crucial in achieving optimal performances at long (1000-m) and short duration races (200 and 500-m). These findings confirm the importance of a larger and compact morphology, as well as superior fitness level, for success in female kayakers. The current results not only identify the weak areas on body composition and physical fitness depending on the maturity status but also the development of specific training programs for FEMALES.

The total phenolic content and radical scavenging activity of Andrographis paniculata has been investigated to estimate the amount of phenolic compounds and diterpene lactones, respectively in the plant extracts. The stem extracts exhibited higher total phenolic content and scavenging activity than those of the leaf extracts from both young and mature plants. A range of 19.6-47.8 mg extract of A. paniculata from different parts of the plant is equivalent to the scavenging activity exhibited by one mg of standard Trolox. HPLC-ESI-MS/MS was also used to identify simultaneously the phytochemicals from the leaves and stems of both young and mature plant samples. Of the identified compounds, seven of the sixteen diterpene lactones, three of the six flavonoids, five of the six phenolic acids and two cyclic acids are reported here for the first time for this species. Multivariate statistical approaches such as Hierarchiral Component Analysis (HCA) and Principle Component Analysis (PCA) have clustered the plant extracts into the leaf and stem groups, regardless of plant age. Further classification based on the phytochemical profiles revealed that mostly phenolic acids and flavonoids were from the young leaf extracts, and diterpenoids and their glycosides from the mature leaf extracts. However, the phytochemical profiles for the stems of both young and mature plants were not significantly different as presented in the dendrogram of HCA and the score plot of PCA. The marker for mature plants might be the m/z 557 ion (dihydroxyl dimethyl 19-[(beta-D-glucopyranosyl)oxy]-19-oxo-ent-labda-8(17),13-dien-16,15-olide), whereas the m/z 521 ion (propyl neoandrographolide) could be the marker for leaf extracts.

It is common wisdom that practice makes perfect; but why do some adults learn better than others? Here, we investigate individuals’ cognitive and social profiles to test which variables account for variability in learning ability across the lifespan. In particular, we focused on visual learning using tasks that test the ability to inhibit distractors and select task-relevant features. We tested the ability of young and older adults to improve through training in the discrimination of visual global forms embedded in a cluttered background. Further, we used a battery of cognitive tasks and psycho-social measures to examine which of these variables predict training-induced improvement in perceptual tasks and may account for individual variability in learning ability. Using partial least squares regression modeling, we show that visual learning is influenced by cognitive (i.e., cognitive inhibition, attention) and social (strategic and deep learning) factors rather than an individual’s age alone. Further, our results show that independent of age, strong learners rely on cognitive factors such as attention, while weaker learners use more general cognitive strategies. Our findings suggest an important role for higher-cognitive circuits involving executive functions that contribute to our ability to improve in perceptual tasks after training across the lifespan.

Nuclear waste programs outside of the US have focused on different host rock types for geological disposal of high-level radioactive waste. Several countries, including France, Switzerland, Belgium, and Japan are exploring the possibility of waste disposal in shale and other clay-rich rock that fall within the general classification of argillaceous rock. This rock type is also of interest for the US program because the US has extensive sedimentary basins containing large deposits of argillaceous rock. LBNL, as part of the DOE-NE Used Fuel Disposition Campaign, is collaborating on some of the underground research laboratory (URL) activities at the Mont Terrimore » URL near Saint-Ursanne, Switzerland. The Mont Terri project, which began in 1995, has developed a URL at a depth of about 300 m in a stiff clay formation called the Opalinus Clay. Our current collaboration efforts include two test modeling activities for the FE heater test and the HG-A leak-off test. This report documents results concerning our current modeling of these field tests. The overall objectives of these activities include an improved understanding of and advanced relevant modeling capabilities for EDZ evolution in clay repositories and the associated coupled processes, and to develop a technical basis for the maximum allowable temperature for a clay repository.« less

Evidence of the role of ANGPTL3, a liver-secreted glycoprotein, in serum lipid turnover, led us to hypothesize that this protein may be involved in modification of the lipid profile induced by exercise-training. Given the lack of data regarding this issue, the main goal of the present study was to investigate the effects of regular participation in a recreational physical activity program on serum ANGPTL3 and selected lipid profile measures in young, apparently healthy female and male adults. We compared serum ANGPTL3, lipid profile measures, common lipid ratios, the Atherogenic Index of Plasma (AIP) and glucose in fasting blood samples derived from 22 active physical education students including active females (AF, N=6) and males (AM, N=16) with samples from 28 relatively sedentary age-matched peers, including female (SF, N=9) and male (SM, N=19) individuals not involved in any regular physical conditioning program. Despite high inter-individual variability of serum ANGPTL3, there was a general tendency toward higher serum ANGPTL3 and HDL-C in women compared to men, but without significant differences related to their physical activity status. Based on both routine lipid profile measures and lipid ratios, all participants had normal lipid profiles, normal glycemia, as well as favorable anthropometric indices not suggesting increased cardiometabolic risk. However, lower levels of the TG/HDL-C ratio and AIP in physically active compared to relatively sedentary participants, reflecting the predominance of large, buoyant LDL particles, strongly support the view of beneficial health-promoting effects of regular participation in recreational sport activities.

We aimed to determine differences in sexual practices, HIV sexual risk behaviors, and HIV risk profile of adolescents and young persons' in rural and urban Nigeria. We recruited 772 participants 15 to 24 years old from urban and rural townships in Nigeria through a household survey. Information on participants' socio-demographic profile (age sex, residential area, number of meals taken per day), sexual practices (vagina, oral and anal sex; heterosexual and homosexual sex; sex with spouse, casual acquaintances, boy/girlfriend and commercial sex workers), sexual behavior (age of sexual debut, use of condom, multiple sex partners, transactional sex and age of sexual partner), and other HIV risk factors (use of alcohol and psychoactive substances, reason for sexual debut, knowledge of HIV prevention and HIV transmission, report of STI symptoms) were collected through an interviewer administered questionnaire. Differences in sexual behavior and sexual practices of adolescents and HIV risk profile of adolescents and young persons resident in urban and rural areas were determined. More than half (53.5%) of the respondents were sexually active, with more residing in the rural than urban areas (64.9% vs 44.1%; p<0.001) and more resident in the rural area reporting having more than one sexual partner (29.5% vs 20.4%; p = 0.04). Also, 97.3% of sexually active respondents reported having vaginal sex, 8.7% reported oral sex and 1.9% reported anal sex. More male than female respondents in the urban area used condoms during the last vaginal sexual intercourse (69.1% vs 51.9%; p = 0.02), and reported sex with casual partners (7.0% vs 15.3%; p = 0.007). More female than male respondents residing in the rural area engaged in transactional sex (1.0% vs 6.7%; p = 0.005). More females than males in both rural (3.6% vs 10.2%; p = 0.04) and urban (4.7% vs 26.6%; p<0.001) areas self-reported a history of discharge. More females than males in both rural (1.4% vs 17.0%; p = 0.04) and urban

Data on the potential behavioral effects of music therapy in autism are scarce. The aim of this study was to investigate whether a musical training program based on interactive music therapy sessions could enhance the behavioral profile and the musical skills of young adults affected by severe autism. Young adults (N = 8) with severe (Childhood Autism Rating Scale >30) autism took part in a total of 52 weekly active music therapy sessions lasting 60 minutes. Each session consisted of a wide range of different musical activities including singing, piano playing, and drumming. Clinical rating scales included the Clinical Global Impression (CGI) scale and the Brief Psychiatric Rating Scale (BPRS). Musical skills-including singing a short or long melody, playing the C scale on a keyboard, music absorption, rhythm reproduction, and execution of complex rhythmic patterns-were rated on a 5-point Likert-type scale ranging from "completely/entirely absent" to "completely/entirely present." At the end of the 52-week training period, significant improvements were found on both the CGI and BPRS scales. Similarly, the patients' musical skills significantly ameliorated as compared to baseline ratings. Our pilot data seem to suggest that active music therapy sessions could be of aid in improving autistic symptoms, as well as personal musical skills in young adults with severe autism.

Approximately 5–10% of subjects with prediabetes become diabetic every year. Inflammation is involved in the development of obesity-related type 2 diabetes (T2D). However, to date, the relationship between inflammation and prediabetes, defined by hemoglobin A1c (HbA1c) ≥ 5.7 and < 6.5%, remains largely unexplored, especially in African Americans. Therefore, in this study we examined a comprehensive panel of 13 cytokines involved in the inflammatory response in overweight/obese subjects with prediabetes. A total of 21 otherwise healthy, overweight/obese, young adult African American females with prediabetes, together with 20 matched overweight/obese controls, were selected for this study. Plasma cytokines were assessed by multiplex cytokine profiling. Plasma concentrations of interleukin (IL)-5, IL-6, IL-7, tumor necrosis factor-α (TNF-α), and granulocyte-monocyte colony-stimulating factor (GM-CSF) were significantly higher in the prediabetic group, as compared to the control group (all p < 0.05). Plasma concentrations of all the other cytokines, interferon-γ (IFN-γ), IL-1β, IL-2, IL-4, IL-8, IL-10, IL-12p70 and IL-13, seemed to be elevated in the prediabetic group, but failed to reach statistical significances. Upon merging both groups, HbA1c was found to be positively correlated with IFN- γ, IL-1β, IL-2, IL-5, IL-7, IL-8, TNF-α and GM-CSF. This study demonstrates elevated levels of various pro-inflammatory cytokines in overweight/obese young subjects with prediabetes, which place them at higher risk of developing T2D and cardiovascular diseases. Our data also call for further investigations in animal models and population cohorts to establish the roles of a variety of pro-inflammatory cytokines in the early development of obesity-related T2D.

The aim of the study was to assess the impact of regular professional sports activity on the endothelial and platelet function in young men. The studied group were 79 young men (18–40 y, 25 athletes and 54 without any regular physical activity). The nitric oxide (NO) metabolic pathway intermediates, oxidative stress markers, mediators of inflammation, and platelet aggregation were measured. Flow mediated dilation (FMD) was studied before and after intravenous 16,0 g L-arginine infusion, which was repeated after oral administration of acetylsalicylic acid (ASA-75 mg/day) for 4 days. Both groups had similar demographic characteristics. In the athletes, there was significantly higher hsCRP level, better serum lipid profile, and lower pulse pressure. Greater baseline FMD in athletes and in response to L-arginine disappeared following ASA treatment. There were no differences in the levels of the NO pathway metabolites. The control group was characterized by higher PAI-1 following ASA treatment and sICAM-1 both at baseline and after ASA, but no differences in MDA and 6-keto-PGF-1 alpha and platelet aggregation were noted. Regular professional physical activity modulates endothelial but not platelet function and may thus exert an effect on overall cardiovascular risk. PMID:28630872

This study was undertaken to determine if young Maori have more permanent bilateral hearing loss, or less severe and profound hearing loss than New Zealand (NZ) Europeans. Data include hearing-impaired children from birth to 19 years of age from the New Zealand Deafness Notification Database (DND) and covering the periods 1982-2005 and 2009-2013. These were retrospectively analysed, as was information on children and young people with cochlear implants. Young Maori are more likely to be diagnosed with permanent hearing loss greater than 26 dB HL, averaged across speech frequencies, with 39-43% of hearing loss notifications listed as Maori. Maori have a lower prevalence of severe/profound losses (n=1571, chi squared=22.08, p=0.01) but significantly more bilateral losses than their NZ European peers (n=595, Chi-squared=9.05, p=0.01). The difference in severity profile is supported by cochlear implant data showing Maori are less likely to receive a cochlear implant. There are significant differences in the proportion of bilateral (compared to unilateral) losses and in the rates and severity profile of hearing loss among young Maori when compared with their NZ European peers. This has implications for screening and other hearing services in NZ.

Recent theories suggest that behavioural addictions and substance use disorders may be the result of the same underlying vulnerability. The present study investigates profiles of family background, personality and mental health factors and their associations with seven behavioural addictions (to the internet, gaming, smartphones, internet sex, gambling, exercise and work) and three substance use disorder scales (for alcohol, cannabis and tobacco). The sample consisted of 5287 young Swiss men (mean age = 25.42) from the Cohort Study on Substance Use Risk Factors (C-SURF). A latent profile analysis was performed on family background, personality and mental health factors. The derived profiles were compared with regards to means and prevalence rates of the behavioural addiction and substance use disorder scales. Seven latent profiles were identified, ranging from profiles with a positive family background, favourable personality patterns and low values on mental health scales to profiles with a negative family background, unfavourable personality pattern and high values on mental health scales. Addiction scale means, corresponding prevalence rates and the number of concurrent addictions were highest in profiles with high values on mental health scales and a personality pattern dominated by neuroticism. Overall, behavioural addictions and substance use disorders showed similar patterns across latent profiles. Patterns of family background, personality and mental health factors were associated with different levels of vulnerability to addictions. Behavioural addictions and substance use disorders may thus be the result of the same underlying vulnerabilities. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

This study explored whether young adults with major depression who are physically active differ in their depression symptom profile from those physically inactive. Analyses included data from 950 (47.6%) men and 1045 women (mean [standard deviation] age = 31.5 [2.6] years) participating in a national study. Participants reported leisure physical activity (International Physical Activity Questionnaire) and ambulatory activity (pedometer steps per day). Diagnosis and symptoms of major depression were assessed using the Composite International Diagnostic Interview. Prevalence of major depression was 5.5% (n = 52) for men and 11.6% (n = 121) for women. Interactions between physical activity and sex were observed for depressed mood, appetite changes, vacillating thoughts, and suicidality (all, p < .050). Among those with major depression, physically active men were significantly less likely to endorse the presence of insomnia (prevalence ratio [PR] = 0.78, 95% confidence interval [CI] = 0.63-0.96), fatigue (PR = 0.82, 95% CI = 0.69-0.99), and suicidality (PR = 0.69, 95% CI = 0.49-0.96) compared with inactive men. Physically active women were significantly less likely to endorse hypersomnia (PR = 0.50, 95% CI = 0.27-0.95), excessive/irrational guilt (PR = 0.76, 95% CI = 0.59-0.97), vacillating thoughts (PR = 0.74, 95% CI = 0.58-0.95), and suicidality (PR = 0.43, 95% CI = 0.20-0.89) compared with inactive women. Associations were adjusted for age, physical health, educational attainment, depression severity, and other depressive symptoms. Among adults with major depression, those physically active seem to differ in their depression symptom profile from those physically inactive.

Mood disorders are characterized by disabling symptoms and cognitive difficulties which may vary in intensity throughout the course of the illness. Sleep-wake cycles and circadian rhythms influence emotional regulation and cognitive functions. However, the relationships between the sleep-wake disturbances experienced commonly by people with mood disorders and the longitudinal changes in their clinical and cognitive profile are not well characterized. This study investigated associations between initial sleep-wake patterns and longitudinal changes in mood symptoms and cognitive functions in 50 young people (aged 13-33 years) with depression or bipolar disorder. Data were based on actigraphy monitoring conducted over approximately 2 weeks and clinical and neuropsychological assessment. As part of a longitudinal cohort study, these assessments were repeated after a mean follow-up interval of 18.9 months. No significant differences in longitudinal clinical changes were found between the participants with depression and those with bipolar disorder. Lower sleep efficiency was predictive of longitudinal worsening in manic symptoms (P = 0.007). Shorter total sleep time (P = 0.043) and poorer circadian rhythmicity (P = 0.045) were predictive of worsening in verbal memory. These findings suggest that some sleep-wake and circadian disturbances in young people with mood disorders may be associated with less favourable longitudinal outcomes, notably for subsequent manic symptoms and memory difficulties. © 2016 European Sleep Research Society.

The U(VI) speciation influenced by a novel Paenibacillus isolate from Mont Terri Opalinus clay.

Bacterial cell walls have a high density of ionizable functional groups available for U(VI) binding, hence have a great potential to affect the speciation of this contaminant in the environment. The studied strain of the genus Paenibacillus is a novel isolate originating from the Mont Terri Opalinus clay formations (Switzerland) which are currently investigated as a potential host rock for future nuclear waste storage. U(VI) binding to the cell surface functional groups was studied by potentiometry combined with time-resolved laser-induced fluorescence spectroscopy (TRLFS). Four bacterial U(VI) surface complexes were identified: R-COO-UO2(+), R-O-PO3-UO2, R-O-PO3H-UO2(+), and (R-O-PO3)2-UO2(2-). The corresponding complex stability constants were calculated to be 5.33 ± 0.08, 8.89 ± 0.04, 12.92 ± 0.05, and 13.62 ± 0.08, respectively. Hence UO2(2+) displays a moderate to strong interaction with the bacterial surface functional groups. In the acidic pH range (pH 3) UO2(2+) binding onto the cell envelope is governed by coordination to hydrogen phosphoryl sites. Upon increasing the pH an increasing coordination of UO2(2+) to carboxylic and deprotonated phosphoryl sites was found. At a pH greater than 7 uranyl hydroxides dominate the speciation. Additionally the bacteria-mediated release of inorganic phosphate in dependence on [U(VI)] at different pH values was studied to assess the influence of phosphate release on U(VI) mobilization.

The aim of the present study was to profile shoulder passive range of motion (ROM) and isometric strength for external (ER) and internal (IR) rotation as part of a preseason screening in adolescent national badminton players. Passive external range of motion (EROM) and internal range of motion (IROM) were examined on the dominant and nondominant shoulder in 31 adolescent national badminton players (12 females and 19 males) with a standard goniometer. Muscle strength was examined with a hand-held dynamometer in ER and IR. Total range of motion (TROM = EROM+IROM) was lower on the dominant side compared with the nondominant side in both groups (P < 0.001). Males were generally stronger than females in all strength measurements except for IR on the dominant side (P < 0.01). In females, IR dominant side strength was greater compared with IR on the nondominant side (P < 0.05). TROM was reduced on the dominant side compared with the nondominant side in young elite badminton players, irrespective of gender. No rotational strength differences existed between the dominant and nondominant side in male players, but in female players a higher IR strength on the dominant side was not balanced by a higher ER strength. © 2012 John Wiley & Sons A/S.

To describe socioeconomic and antiretroviral (ARV) drug resistance profiles among young pregnant women infected with HIV-1. A public health antenatal programme responsible for screening ∼90 000 pregnant women per year for nine different infectious diseases in Central Western Brazil. 96 young pregnant women (15-24 years) infected with HIV-1. Standard interviews and blood samples were taken at the time of recruitment, at the first medical appointment after confirmation of diagnosis of HIV-1 infection, and before ARV prophylaxis initiation. Clinical and laboratory data were retrieved from medical files. HIV-1 pol gene sequences (entire protease/PR, partial reverse transcriptase/RT) were obtained from plasma RNA. ARV resistance mutations (CPR/Stanford HIV-1; International AIDS Society-USA databases) were identified. The median age was 21 years; most reported <8 years education; 73% were recently diagnosed. Approximately 20% (19/96) presented late for antenatal care (after 26 gestational weeks), while 49% reported ≥2 previous pregnancies. Possible heterosexual transmission by an HIV-1 infected partner (17%) and commercial sex work (2%) were reported. The median of CD4 cell count was 526 cells/mm(3); the median viral load was: 10 056 copies/mL in ARV-naïve (48/96) patients and 5881 copies/mL in ARV-exposed (48/96) patients. Two probable seroconversion cases during pregnancy were identified in adolescents. One mother-to-child transmission case (1.0%) was observed. Transmitted drug resistance among ARV-naïve patients was 9.3% (CI 95% 3.3% to 19.6%); secondary drug resistance among ARV-exposed patients was 12.5% (CI 95% 4.7% to 25.6%). Despite high access to antenatal care, the low socioeconomic-educational profiles seen in these young HIV-1-infected women highlight the necessity of improved public health educational and preventive strategies regarding HIV infection and early unplanned pregnancy.

Asian subjects are at increased cardio-metabolic risk at comparatively lower body mass index (BMI) compared with white subjects. Sympathetic nervous system activation and dyslipidemia, both characteristics of increased adiposity, appear to be related. We therefore analyzed the association of muscle sympathetic nerve activity (MSNA) with the plasma lipidomic profile in young adult Asian and white subjects. Blood samples were collected from 101 participants of either Asian or white background (age, 18 to 30 years; BMI, 28.1 ± 5.9 kg/m2). Lipids were extracted from plasma and analyzed using electrospray ionization-tandem mass spectrometry. MSNA was quantified using microneurography. The association of MSNA and obesity with lipid species was examined using linear regression analysis. The plasma concentrations of total dihydroceramide, ceramide, GM3 ganglioside, lysoalkylphosphatidylcholine, alkenylphosphatidylethanolamine, and lysophosphatidylinositol were elevated in the Asian subjects relative to the white subjects. After adjustment for confounders, diacylglycerols and triacylglycerols, cholesterol esters, phosphatidylinositols, phosphatidylethanolamines, and phosphatidylglycerols bore significant associations with MSNA but only in the Asian subjects. These associations remained significant after further adjustment for the participants' degree of insulin resistance and appeared not to be related to differences in diet macronutrient content between groups. The lipidomic profile differs between Asian and white subjects. There exists a strong relationship between certain lipid species and MSNA. The association is stronger in Asian subjects, despite their lower BMI. This study demonstrates an association between circulating lipids and central sympathetic outflow. Whether the stronger association between the lipid profile and sympathetic activation underpins the apparent greater risk posed by increased adiposity in Asian individuals merits further attention.

Caloric restriction (CR) ameliorates cardiac dysfunction associated with obesity. However, most of the studies have been performed under severe CR (30–65% caloric intake decrease) for several months or even years in aged animals. Here, we investigated whether mild (20% food intake reduction) and short-term (2-weeks) CR prevented the obese cardiomyopathy phenotype and improved the metabolic profile of young (14 weeks of age) genetically obese Zucker fa/fa rats. Heart weight (HW) and HW/tibia length ratio was significantly lower in fa/fa rats after 2 weeks of CR than in counterparts fed ad libitum. Invasive pressure measurements showed that systolic blood pressure, maximal rate of positive left ventricle (LV) pressure, LV systolic pressure and LV end-diastolic pressure were all significantly higher in obese fa/fa rats than in lean counterparts, which were prevented by CR. Magnetic resonance imaging revealed that the increase in LV end-systolic volume, stroke volume and LV wall thickness observed in fa/fa rats was significantly lower in animals on CR diet. Histological analysis also revealed that CR blocked the significant increase in cardiomyocyte diameter in obese fa/fa rats. High resolution magic angle spinning magnetic resonance spectroscopy analysis of the LV revealed a global decrease in metabolites such as taurine, creatine and phosphocreatine, glutamate, glutamine and glutathione, in obese fa/fa rats, whereas lactate concentration was increased. By contrast, fatty acid concentrations in LV tissue were significantly elevated in obese fa/fa rats. CR failed to restore the LV metabolomic profile of obese fa/fa rats. In conclusion, mild and short-term CR prevented an obesity-induced cardiomyopathy phenotype in young obese fa/fa rats independently of the cardiac metabolic profile. PMID:28203206

The present study was aimed at investigating the effects of sleep deprivation and dietary irregularities during Ramadan intermittent fasting (RIF) on selective fitness profile parameters in young untrained male Muslim individuals. 77 untrained Muslim men were recruited in the study. They were divided into the experimental group (EG; n=37, age: 22.62±1.77 years) and the control group (CG; n=40, age: 23.00±1.48 years). EG was undergoing RIF while CG abstained. Aerobic fitness, anaerobic capacity or high-intensity efforts (HIEs), agility, flexibility, vertical jump height and handgrip strength were measured on 8 separate occasions-15 days before RIF, 7 days before RIF, 1st day of RIF, 7th day of RIF, 15th day of RIF, 21st day of RIF, last day of RIF and 15 days after RIF. Aerobic fitness and HIE showed a significant difference (p<0.05) during RIF in EG. Agility and flexibility score showed a significant decrease in EG during RIF, whereas changes in the vertical jump score (VJT) and handgrip strength were statistically insignificant. Studied parameters showed an insignificant variation in CG during RIF. Aerobic fitness, HIEs, agility and flexibility showed a significant intergroup variation during different experimental trials. The present investigation revealed that RIF had adverse effects on aerobic fitness, HIEs, agility and flexibility of young untrained Muslims of Kolkata, India. VJT, waist-hip ratio and handgrip strength were not affected by RIF in the studied population. Mild but statistically insignificant reduction in body mass was also reflected after the mid-Ramadan week.

JAEA participated in the Fault Slip Experiment of Mont Terri Project which aims at understanding (i) the conditions for slip activation and stability of clay faults, and (ii) the evolution of the coupling between fault slip, pore pressure and fluids migration. The experiment uses SIMFIP probe to estimate (i) the hydraulic and elastic properties of fault zone elements, (ii) the state of stresses across the fault zone and (iii) the fault zone apparent strength properties (friction coefficient and cohesion). To elaborate on the Fault Slip Experiment, JAEA performed friction experiment of borehole cores of depths 47.2m and 37.3m using a rotary-shear low to high-velocity friction apparatus at Institute of Geology, China Earthquake Administration. Friction experiments were performed either dry with room humidity or with 30wt% of H2O, at a normal stress of 1.38 MPa and at low to intermediate slip rates ranging 0.21 microns/s to 2.1mm/s. Sample from a depth of 37.3 m is a fault rock with scaly fabric with calcite veins, whereas that from 47.2 m in depth is a pelitic rock that disaggregates easily with water. Main experimental results are summarized as follows. (1) Gouge samples from both depths exhibit slight velocity-strengthening at V below 0.021 mm/s and notable velocity strengthening at V above approximately 0.021 mm/s. Frictional regimes can be classified into low-velocity and intermediate-velocity regimes, characterized by slight and clear velocity-strengthening behaviors, respectively. (2) Wet gouge from a depth of 47.2 m has mss of 0.12 0.2 at low V and 0.11 0.24 at intermediate V, while dry gouge from the same depth has mss two to three times as high as that for the wet gouge from the same depth. (3) In contrast, both dry and wet gouges from a depth of 37.3 m has mss of around 0.4 to 0.74 at low V and from around 0.45 to 0.75 at intermediate V. There are almost no differences between the dry and wet gouges from this depth (4) The wet gouge from 47.2 m depths has

In contemporary Chinese society, obstacles such as frequent violence against medical workers and tense doctor-patient relationships affect the health of Chinese doctors. This study attempted to explore the quality of life (QOL) of young clinical doctors in public hospitals in China's developed cities to study the psychometric properties of QOL and related risk factors of doctors' health. This study sampled young doctors aged 15-45 in 18 public hospitals of three cities in East China (Shanghai, Nanjing, and Hangzhou, N = 762). The Nottingham Health Profile was used to measure QOL, the dependent variable of this study. Methodologies such as reliability analysis, mean comparison, and exploratory factor analysis were used to study related psychometric properties. Almost 90 % of young Chinese clinical doctors have a bachelor's degree or above. Approximately 70.4 % of the doctors have relatively low job titles. Among the sample, 76.1 % have a monthly income ranging from USD 326 to USD 1139, and 91.3 % work over eight hours daily. These respondents have poor sleeping habits and mental functions, but have relatively good physical functions. Being female, low education, low job title, low salary, and long work hours are factors associated with doctors' poor QOL. Regression analysis results emphasize the great effect of high education on the improvement of QOL. Young clinical doctors in public hospitals in Chinese developed cities have poor QOL. Reforms on the current medical health system, improving the working environment of doctors and relieve their occupational stress should be required.

The aim of the study was to evaluate effects of Finnish sauna bathing on lipid profile in healthy, young men. Sixteen male subjects (20-23 years) were subjected to 10 sauna bathing sessions in a Finnish sauna every 1 or 2 days. The mean sauna temperature was 90±2°C, while humidity was 5-16%. Each session consisted of three 15-minute parts and a 2-minute cool-down between them. The following measurements were taken before and after the sauna sessions: body mass, heart rate, body skinfold thickness. The percentage fat content and then, the lean body mass were calculated. Total cholesterol, triacylglycerols, lipoprotein cholesterol LDL and HDL were measured in blood samples. A statistically significant decrease of total cholesterol and LDL cholesterol was observed during 3 weeks of sauna treatment and in the week afterwards. A significant decline in triacylglycerols was found directly after the 1st and 24 h directly after the 10th sauna session. After the 10th sauna session the level of HDL cholesterol remained slightly increased, but this change was not statistically significant. A decrease in blood plasma volume was found directly after the 1st and the last sauna bathing session due to perspiration. An adaptive increase in blood plasma volume was also found after the series of 10 sauna sessions. Ten complete sauna bathing sessions in a Finnish sauna caused a reduction in total cholesterol and LDL cholesterol fraction levels during the sessions and a gradual return of these levels to the initial level during the 1st and the 2nd week after the experiment. A small, statistically insignificant increase in HDL-C level and a transient decline in triacylglycerols were observed after those sauna sessions. The positive effect of sauna on lipid profile is similar to the effect that can be obtained through a moderate-intensity physical exercise.

It has been suggested that addictive behaviors related to consumption of specific foods could contribute to overeating and obesity. Although energy-dense, hyper-palatable foods are hypothesized to be associated with addictive-like eating behaviors, few studies have assessed this in humans. To evaluate in young adults whether intakes of specific foods are associated with 'food addiction', as assessed by the Yale Food Addiction Scale (YFAS), and to describe the associated nutrient intake profiles. Australian adults aged 18-35 years were invited to complete an online cross-sectional survey including demographics, the YFAS and usual dietary intake. Participants were classified as food addicted (FAD) or non-addicted (NFA) according to the YFAS predefined scoring criteria. A total 462 participants (86% female, 73% normal weight) completed the survey, with 14.7% ( n  = 68) classified as FAD. The FAD group had a higher proportion of females ( p  = .01) and higher body mass index ( p  < .001) compared to NFA. Higher YFAS symptom scores were associated with higher percentage energy intake (%E) from energy-dense, nutrient-poor foods including candy, take out and baked sweet products, as well as lower %E from nutrient-dense core foods including whole-grain products and breakfast cereals. These remained statistically significant when adjusted for age, sex and BMI category ( p  = .001). Statistically significant associations were identified between YFAS assessed food addiction and dietary intake, specifically intakes of energy-dense, nutrient-poor foods. However, the effect sizes were small limiting clinical applications. Further examination of the relationship between addictive-like eating and intake of specific foods in a nationally representative sample is warranted.

Coupled thermal–hydrological–mechanical (THM) processes in the near field of deep geological repositories can influence several safety features of the engineered and geological barriers. Among those features are: the possibility of damage in the host rock, the time for re-saturation of the bentonite, and the perturbations in the hydraulic regime in both the rock and engineered seals. Within the international cooperative code-validation project DECOVALEX-2015, eight research teams developed models to simulate an in situ heater experiment, called HE-D, in Opalinus Clay at the Mont Terri Underground Research Laboratory in Switzerland. The models were developed from the theory of poroelasticity in ordermore » to simulate the coupled THM processes that prevailed during the experiment and thereby to characterize the in situ THM properties of Opalinus Clay. The modelling results for the evolution of temperature, pore water pressure, and deformation at different points are consistent among the research teams and compare favourably with the experimental data in terms of trends and absolute values. The models were able to reproduce the main physical processes of the experiment. In particular, most teams simulated temperature and thermally induced pore water pressure well, including spatial variations caused by inherent anisotropy due to bedding.« less

Physiological profiles are described for 30 healthy young (20-31 years) and 30 healthy older (50-62 years) men. Half of the individuals in each group reported that during the previous five years they participated frequently in strenuous physical exercises; the other half reported sedentary lifestyles. A treadmill exercise test was used to determine maximal aerobic power (VO2 max). Heart rate and blood pressure were measured during rest, maximal exercise and recovery. The active older men demonstrated significantly lower resting heart rates, lower resting systolic and diastolic blood pressures, higher VO2 max, lower maximal exercise diastolic blood pressure and lower recovery heart rates than the age-matched sedentary men. Compared with the young sedentary men, the older active men had lower resting heart rates and higher VO2 max, walked longer on the treadmill, had lower recovery heart rates and weighed less. Older active men also had higher VO2 max levels than young sedentary men. In summary, physiological profiles of the older active men more closely resembled profiles of active men who were 30 years younger than those of older sedentary men. These results emphasize the range of benefits associated with exercise. PMID:3228686

The purpose of this study was to get new information from several sources about the background factors of Finnish smokers, snuffers, and dual users. Profiles of young smokers and snuffers were investigated in association with restorative treatment need, oral hygiene, eating habits, physical activity, body mass index (BMI), psychological and socioeconomic factors. The study group comprised 3420 conscripts. The data were collected from four different sources: a health examination including an oral health screening, a computer-based questionnaire for investigating individual background factors, a psychological test assessing cognitive skills, and the Cooper test. Statistical analyses comprised cross tabulation and binary logistic regression modelling. The odds for smoking were the greatest among those who had DT (Decayed teeth) > 0, used energy drinks or alcohol regularly, or whose parents were divorced. A score of ≥2900 m in the Cooper test, a higher physical exercise level, a higher own education level, and using sports drinks decreased the odds for smoking. The odds for snuffing were higher among those who ran >2500 m in the Cooper test, had a BMI of ≥25, used sports/energy drinks, or exercised regularly, and lower among those who achieved good results in the cognitive test. Using energy/sports drinks or alcohol was positively and a higher education level was negatively associated with dual use. Along with increasing prevalence of snuffing, heterogeneity is likely among snuffers. Good cognitive skills may prevent from smoking and snuffing.

The pervasiveness, connectedness, and intrusiveness of social network site use among young adolescents.

Espinoza, Guadalupe; Juvonen, Jaana

2011-12-01

Young adolescents are quickly becoming avid users of social networking sites (SNSs); however, little is known regarding how they use these sites. The goal of the present study was to examine the extent to which young adolescents use SNSs, with whom they connect via these sites, and whether SNS use disrupts daily functioning. Among 268 middle-school students surveyed, 63% reported having their own profile page on an SNS. On average, adolescents reported having 196 SNS contacts (friends), most of whom were known peers. Young adolescents with an SNS spent most of their time viewing and responding to comments written on their profile page. Among the SNS users, 39% reported getting behind on schoolwork and 37% reported losing sleep at least once because they were visiting an SNS. As SNS use becomes embedded in young teens' daily lives, it is important to better understand how such use affects their daily adaptive functioning.

Long-term endurance exercise severely affects metabolism in both human and animal athletes resulting in serious risk of metabolic disorders during or after competition. Young horses (up to 6 years old) can compete in races up to 90 km despite limited scientific knowledge of energetic metabolism responses to long distance exercise in these animals. The hypothesis of this study was that there would be a strong effect of endurance exercise on the metabolomic profiles of young horses and that the energetic metabolism response in young horses would be different from that of more experienced horses. Metabolomic profiling is a powerful method that combines Nuclear Magnetic Resonance (NMR) spectrometry with supervised Orthogonal Projection on Latent Structure (OPLS) statistical analysis. 1H-NMR spectra were obtained from plasma samples drawn from young horses (before and after competition). The spectra obtained before and after the race from the same horse (92 samples) were compared using OPLS. The statistical parameters showed the robustness of the model (R2Y = 0.947, Q2Y = 0.856 and cros-validated ANOVA p < 0.001). For confirmation of the predictive value of the model, a test set of 104 sample spectra were projected by the model, which provided perfect predictions as the area under the receiving-operator curve was 1. The metabolomic profile determined with the OPLS model showed that glycemia after the race was lower than glycemia before the race, despite the involvement of lipid and protein catabolism. An OPLS model was calculated to compare spectra obtained on plasma taken after the race from 6-year-old horses and from experienced horses (cross-validated ANOVA p < 0.001). The comparison of metabolomic profiles in young horses to those from experienced horses showed that experienced horses maintained their glycemia with higher levels of lactate and a decrease of plasma lipids after the race.

To examine the association between breast-feeding and blood pressure, anthropometry and plasma lipid profile in both adolescence and young adulthood. Longitudinal study of biological and behavioural risk factors for CVD. The Young Hearts Project, Northern Ireland. Schoolchildren aged 12 years and 15 years who participated in a cross-sectional study of lifestyle and health, and who were followed up as young adults aged 20-25 years. There was no significant difference in height, weight, BMI, skinfold thickness measurements, blood pressure or plasma lipid profile in adolescents who had been breast-fed compared with those who had not been breast-fed. However, by the time these adolescents had reached adulthood, those who had been breast-fed were significantly taller than those who had not been breast-fed (standing height, P = 0.013; leg length, P = 0.035). Specifically, the breast-fed group was on average taller by 1.7 cm (95 % CI 0.4, 3.0 cm) and had longer legs by 1.0 cm (95 % CI 0.1, 1.9 cm). There was no significant difference in other anthropometric measures, blood pressure or plasma lipid profile in adults who had been breast-fed compared with those who had not been breast-fed. Compared with those who had not been breast-fed, individuals who had been breast-fed were taller in adulthood. Given the known association of increased adult height with improved life expectancy, the results from the present study support a beneficial effect of breast-feeding.

The prevalence of obesity, as well as evidence about this pathology as a risk factor for cognitive decline and dementia in the elderly, is increasing worldwide. Executive functions have been found to be compromised in most studies, although the specific results are dissimilar. Obese young women constitute an interesting study and intervention group, having been found to be unaffected by age and hormonal negative effects on cognition and considering that their health problems affect not only themselves but their families and offspring. The objective of the present study was to compare the executive performance of obese young women with that of a healthy control group. A cross-sectional study was done among premenopausal women from a public hospital in Buenos Aires. The sample comprised 113 participants (32 healthy controls and 81 obese women), who were evaluated for depressive and anxiety symptoms (Beck Depression Inventory-II and State-Trait Anxiety Inventory) and executive functioning (Trail-Making Test B, Stroop Color and Word Test, Wisconsin Card Sorting Test, and verbal fluency test). Statistical analysis was done by using the SPSS version 20.0 software. Among executive functions, a significant difference was found between groups in inhibition (p<0.01). No correlation was found between psychopathologic measures and Stroop Test Interference results. We found slight correlations between Stroop Test Interference results, waist circumference, fat mass and HDL-cholesterol. In obese group, there was a negative slightly correlation between this cognitive test and 2h post-load glucose level. Inhibition was decreased in our obese young women group, and glucose/lipid metabolism may be involved in this association. The cognitive impairment is comparable with that described in addictive conditions. Our conclusions support the concept of multidisciplinary management of obese patients from the time of diagnosis.

Background Many aging changes seem similar to those elicited by sleep-deprivation and psychosocial stress. Further, sleep architecture changes with age suggest an age-related loss of sleep. Here, we hypothesized that sleep deprivation in young subjects would elicit both stress and aging-like transcriptional responses. Methodology/Principal Findings F344 rats were divided into control and sleep deprivation groups. Body weight, adrenal weight, corticosterone level and hippocampal CA1 transcriptional profiles were measured. A second group of animals was exposed to novel environment stress (NES), and their hippocampal transcriptional profiles measured. A third cohort exposed to control or SD was used to validate transcriptional results with Western blots. Microarray results were statistically contrasted with prior transcriptional studies. Microarray results pointed to sleep pressure signaling and macromolecular synthesis disruptions in the hippocampal CA1 region. Animals exposed to NES recapitulated nearly one third of the SD transcriptional profile. However, the SD -aging relationship was more complex. Compared to aging, SD profiles influenced a significant subset of genes. mRNA associated with neurogenesis and energy pathways showed agreement between aging and SD, while immune, glial, and macromolecular synthesis pathways showed SD profiles that opposed those seen in aging. Conclusions/Significance We conclude that although NES and SD exert similar transcriptional changes, selective presynaptic release machinery and Homer1 expression changes are seen in SD. Among other changes, the marked decrease in Homer1 expression with age may represent an important divergence between young and aged brain response to SD. Based on this, it seems reasonable to conclude that therapeutic strategies designed to promote sleep in young subjects may have off-target effects in the aged. Finally, this work identifies presynaptic vesicular release and intercellular adhesion molecular

2006-09-01

The health issues of young adulthood have received relatively little attention compared with those of adolescence, although the critical issues in young adulthood parallel those of adolescence. Young adults often fare worse than adolescents on health indicators, with many measures of negative outcomes--including rates of injury, homicide, and substance use--peaking during the young adult years. The contextual factors shaping health status and access to care in young adulthood differ significantly from the context of adolescence. This article synthesizes national data to present a health profile of young adults, reviewing social indicators that describe the context of young adulthood and presenting measures of health status. We examine mortality, morbidity, risky behaviors, and health care access and utilization, identifying the most significant gender and racial/ethnic disparities. The article also identifies limitations of existing data and offers suggestions for future research and health monitoring in this area. We conclude with a discussion of current efforts to address the health and well-being of young adults and argue for creating a national health agenda for young adults that includes research, programs and policies to address health issues during this period of the lifespan.

Marriage Matters But How Much? Marital Centrality Among Young Adults.

Marriage, once a gateway to adulthood, is no longer as widely considered a requirement for achieving adult status. With declining marriage rates and delayed marital transitions, some have wondered whether current young adults have rejected the traditional notion of marriage. Utilizing a sample of 571 young adults, the present study explored how marital centrality (the expected importance to be placed on the marital role relative to other adult roles) functioned as a unique and previously unexplored marital belief among young adults. Results suggested that marriage remains an important role for many young adults. On average, young adults expected that marriage would be more important to their life than parenting, careers, or leisure activities. Marital centrality profiles were found to significantly differ based on both gender and religiosity. Marital centrality was also associated with various outcomes including binge-drinking and sexual activity. Specifically, the more central marriage was expected to be, the less young adults engaged in risk-taking or sexual behaviors.

Young Adult Identities and Their Pathways: A Developmental and Life Course Model

Benson, Janel E.; Elder, Glen H.

2013-01-01

Developmental and life course studies of young adult identities have focused on two dimensions, subjective age and psychosocial maturity. This study examines the developmental synchrony of these two processes. In a longitudinal sample of young adults from Add Health (18 to 22), a person-centered analysis of indicators of these dimensions identified four identity profiles. Two depict early and late patterns of identity; the others represent contrasting types of discordance, “pseudo-adult”, subjective age more advanced than maturation level and “anticipatory”, with subjective age less advanced than maturational level. The profiles vary by gender, socioeconomic status, and race-ethnicity as well as by adolescent (ages12–16) pubertal maturation, psychosocial adjustment, and family context. These results provide support for a more holistic, interdisciplinary understanding of adult identity, and show that young adult identities in the Add Health sample follow differentiated paths into the adult years, with largely unknown consequences for the subsequent life course.

This study covers the lifestyle component of the problems related to young drivers' accident risk. The purpose of the study is to measure the relationship between lifestyle and accident risk, and to identify specific high-risk and low-risk groups. Lifestyle is measured through a questionnaire, where 20-year-olds describe themselves and how often they deal with a large number of different activities, like sports, music, movies, reading, cars and driving, political engagement, etc. They also report their involvement in traffic accidents. With a principal component analysis followed by a cluster analysis, lifestyle profiles are defined. These profiles are finally correlated to accidents, which makes it possible to define high-risk and low-risk groups. The cluster analysis defined 15 clusters including four high-risk groups with an average overrisk of 150% and two low-risk groups with an average underrisk of 75%. The results are discussed from two perspectives. The first is the importance of theoretical understanding of the contribution of lifestyle factors to young drivers' high accident risk. The second is how the findings could be used in practical road safety measures, like education, campaigns, etc.

Cigarette smoking is a world-wide habit and an important risk factor for cancer. It was known that cigarette smoking can change the expression of circulating microRNAs (miRNAs) in healthy middle-aged adults. However, it remains unclear whether cigarette smoking can change the levels of circulating miRNAs in young healthy smokers and whether there are differences in cancer susceptibility for the two cases. In this study, the miRNA expression profiles of 28 smokers and 12 non-smokers were determined by Agilent human MicroRNA array. We further performed bioinformatics analysis for the differentially expressed miRNAs. The result showed that 35 miRNAs were differentially expressed. Among them, 24 miRNAs were up-regulated and 11 miRNAs were down-regulated in smokers. Functional enrichment analysis showed that the deregulated miRNAs are related to immune system and hormones regulation. Strikingly, the up-regulated miRNAs are mostly associated with hematologic cancers, such as lymphoma, leukemia. As a comparison, the up-regulated plasma miRNAs in middle-aged smokers are mostly associated with solid cancers, such as hepatocellular carcinoma and lung cancer, suggesting that smoking could have different influences on young adults and middle-aged adults. In a conclusion, we identified the circulating miRNAs deregulated by cigarette smoking and revealed that the age-dependent deregulated miRNAs tend to be mainly involved in different types of human cancers.

Simultaneous contributions of self-esteem, depression, and anxiety to weight and perceived physical health in young adults is understudied. A diverse sample of 424 young adults completed measures of shape/weight based self-esteem, depression, anxiety, and perceived physical health. Height and weight were measured to calculate body mass index (BMI). Latent profile analysis was conducted to derive patterns of depression, anxiety, and shape/weight based self-esteem. Then, we examined the association of the profiles with weight status and perceived physical health. Three profiles emerged: (1) High Shape/Weight Influence (HSWI); (2) Low Shape/Weight, Depression, & Anxiety Influence (LSWDAI); and (3) High Depression & Anxiety Influence (HDAI). The HSWI profile had significantly higher BMI than the LSWDAI and HDAI profiles, and significantly lower perceived physical health than the LSWDAI profile. Over emphasis on shape/weight, regardless of depression and anxiety, is associated with elevated weight and negative internalized health views. Copyright © 2018 Elsevier Ltd. All rights reserved.

Based on previous studies reporting on the association of objective sleep duration and physiologic changes (i.e., increased cortisol) in children, we examined the role of objective sleep duration on differentiating behavioral profiles in children with insomnia symptoms. Seven hundred children (ages 5-12, 47.8% male) from the Penn State Child Cohort underwent a nine-hour polysomnography and parent completed Pediatric Behavior Scale. Insomnia symptoms were defined as parent report of difficulty falling and/or staying asleep, sleep disordered breathing as an AHI of ≥1, and objective short sleep duration as a total sleep time < 7.7 h. Children with insomnia symptoms demonstrated more overall behavioral problems than controls. Significant interactions between insomnia symptoms and objective sleep duration on scores of externalizing behaviors, mood variability and school problems were found. Profile analyses showed that children with insomnia symptoms and normal sleep duration were associated with clinically elevated externalizing behaviors, inattention, mood variability, and school problems, while children with insomnia and short sleep duration were associated with an overall elevated profile in which internalizing behaviors were more prominent. Childhood insomnia symptoms are associated with a wide array of behavioral problems, for which objective sleep duration is useful in differentiating behavioral profiles. Children with insomnia symptoms and normal sleep duration had a behavioral profile consistent with limit-setting and rule-breaking behaviors, while children with insomnia symptoms and short sleep duration had a behavioral profile more consistent with internalizing behaviors resembling that of psychophysiological disorders.

The aim of the study was to describe anthropometric and physical characteristics of elite young road-race motorcyclists (MC). 27 riders (15.6±1.1 years, 54.6±6.9 kg, 166.9±6.7 cm) competing at international elite level participated in this study. Anthropometric variables, hand grip and lumbar isometric strength, and lower-body muscular strength were measured. Comparisons of the MC and a reference group of Spanish physically active adolescents (16.0±0.6 years) showed that the riders were significantly lighter (-12.5 kg), and smaller (-4.7 cm). Riders also had significantly lower values for almost all skinfolds, and for all the measured girths (except forearm) than the reference group. Motorcyclists showed significantly less percent body fat (%BF) and higher muscle mass, and differences were observed for somatotype components compared to the reference group, except for the ectomorphy. Somatotype could be defined as mesomorphic-ectomorph (2.5-4.4-3.7). Mean (±SD) values of all riders were 34.8±5.0 cm for vertical jump height, 402.1±74.5 N for the right hand and 370.7±77.5 N for the left hand strengths, and 120.6±19.3 kg for lumbar isometric strength, respectively. Results demonstrate that MC are small and light, with lower body mass index, skinfolds, girth and breadth dimensions, and %BF than a reference group and other athletes, with high values of hand grip and lumbar isometric strength. © Georg Thieme Verlag KG Stuttgart · New York.

Since plutonium could be released from nuclear waste disposal sites, the exploration of the complex interaction processes between plutonium and bacteria is necessary for an improved understanding of the fate of plutonium in the vicinity of such a nuclear waste disposal site. In this basic study, the interaction of plutonium with cells of the bacterium, Sporomusa sp. MT-2.99, isolated from Mont Terri Opalinus Clay, was investigated anaerobically (in 0.1 M NaClO 4 ) with or without adding Na-pyruvate as an electron donor. The cells displayed a strong pH-dependent affinity for Pu. In the absence of Na-pyruvate, a strong enrichment of stable Pu(V) in the supernatants was discovered, whereas Pu(IV) polymers dominated the Pu oxidation state distribution on the biomass at pH 6.1. A pH-dependent enrichment of the lower Pu oxidation states (e.g., Pu(III) at pH 6.1 which is considered to be more mobile than Pu(IV) formed at pH 4) was observed in the presence of up to 10 mM Na-pyruvate. In all cases, the presence of bacterial cells enhanced removal of Pu from solution and accelerated Pu interaction reactions, e.g., biosorption and bioreduction.

OBJECTIVES While progress has been made to reduce adolescent pregnancies in the United States, rates of unplanned pregnancy among young adults (18–29 years) remain high. In this study, we assessed factors associated with perceived likelihood of pregnancy (likelihood of getting pregnant/getting partner pregnant in the next year) among sexually experienced young adults who were not trying to get pregnant and had ever used contraceptives. METHODS We conducted a secondary analysis of 660 young adults, 18–29 years old in the United States, from the cross-sectional National Survey of Reproductive and Contraceptive Knowledge. Logistic regression and classification tree analyses were conducted to generate profiles of young adults most likely to report anticipating a pregnancy in the next year. RESULTS Nearly one-third (32%) of young adults indicated they believed they had at least some likelihood of becoming pregnant in the next year. Young adults who believed that avoiding pregnancy was not very important were most likely to report pregnancy likelihood (odds ratio [OR], 5.21; 95% CI, 2.80–9.69), as were young adults for whom avoiding a pregnancy was important but not satisfied with their current contraceptive method (OR, 3.93; 95% CI, 1.67–9.24), attended religious services frequently (OR, 3.0; 95% CI, 1.52–5.94), were uninsured (OR, 2.63; 95% CI, 1.31–5.26), and were likely to have unprotected sex in the next three months (OR, 1.77; 95% CI, 1.04–3.01). DISCUSSION These results may help guide future research and the development of pregnancy prevention interventions targeting sexually experienced young adults. PMID:25782849

Similar post-stress metabolic trajectories in young and old flies.

Colinet, Hervé; Renault, David

2018-02-01

Homeostenosis (i.e. decline in stress resistance and resilience with age) is a fundamental notion of the biogerontology and physiology of aging. Stressful situations typically challenge metabolic homeostasis and the capacity to recover from a stress-induced metabolic disorder might be particularly compromised in senescent individuals. In the present work, we report the effects of aging on low temperature stress tolerance and metabolic profiles in Drosophila melanogaster females of different ages. Adult flies aged 4, 16, 30 and 44days were subjected to acute and chronic cold stress, and data confirmed a strong decline in cold tolerance and resilience of old flies compared to young counterparts. Using quantitative target GC-MS analysis, we found distinct metabolic phenotypes between young (4day-old) and old (44day-old) flies, with glycolytic pathways being differentially affected between the two age groups. We also compared the robustness of metabolic homeostasis in young vs. old flies when exposed to cold stress using time-series metabolic analysis. In both age groups, we found evidence of strong alteration of metabolic profiles when flies were exposed to low temperature stress. Interestingly, the temporal metabolic trajectories during the recovery period were similar in young and old flies, despite strong differences in thermotolerance. In conclusion, metabolic signatures markedly changed with age and homeostenosis was observed in the phenotypic response to cold stress. However, these changes did not reflect in different temporal homeostatic response at metabolic level. Copyright © 2017 Elsevier Inc. All rights reserved.

Exercise may increase production of reactive oxygen species (ROS) enhancing oxidative stress. Antioxidants can efficiently scavenge ROS before they initiate oxidative damage of biomolecules such as enzymes, nucleic acids, lipids and lipoproteins in the body. Vitamin C, an important antioxidant, may affect oxidative stress in living organism. Therefore, this study was carried out to investigate the effects of exercise and vitamin C on thiobarbituric acid-reactive substance (TBARS), lipid profile, erythrocyte and platelet indices in young soccer players. This investigation was carried out on twenty two male volunteer players in three groups. The first group was examined as a control. The second group was only exposed to exercise. The third group was exposed to exercise plus vitamin C (500 mg/day) administered per oral. The players were 23.50±0.59 year-old, 67.66±1.52 kg body weight and 1.74±0.03 m height. Blood samples were collected in vacutainer tubes for analysis of biochemical and hematological parameters. While the levels of high density lipoprotein-cholesterol (HDL-C) were significantly increased (P<0.05) with only exercise, the cholesterol and low density lipoprotein-cholesterol (LDL-C) were decreased (P<0.05 to P<0.01) with exercise and exercise plus vitamin C treatment. While TBARS levels were increased (P<0.05) with exercise training, it was decreased (P<0.05) with exercise plus vitamin C treatment. The platelet counts (PLT), mean platelet volume (MPV), plateletcrit (PCT) and red blood cell distribution width (RDW) were significantly decreased (P<0.05) with exercise plus vitamin C. There were significantly correlations (P<0.05 to P<0.01) between lipid values and erythrocyte and platelet indices. In light of these results, exercise may play a role in decreasing of LDL-C and in increasing of HDL-C. In addition, exercise plus vitamin C may diminish TBARS-levels and may affect the values of PLT, MPV, PCT and RDW in young soccer players.

The Young's modulus of thin conical InP nanowires with either wurtzite or mixed "zinc blende/wurtzite" structures was measured. It has been shown that the value of Young's modulus obtained for wurtzite InP nanowires (E [0001] = 130 ± 30 GPa) was similar to the theoretically predicted value for the wurtzite InP material (E [0001] = 120 ± 10 GPa). The Young's modulus of mixed "zinc blende/wurtzite" InP nanowires (E [111] = 65 ± 10 GPa) appeared to be 40% less than the theoretically predicted value for the zinc blende InP material (E [111] = 110 GPa). An advanced method for measuring the Young's modulus of thin and flexible nanostructures is proposed. It consists of measuring the flexibility (the inverse of stiffness) profiles 1/k(x) by the scanning probe microscopy with precise control of loading force in nanonewton range followed by simulations.

Early identification of high-risk individuals is key for the prevention of cardiovascular disease (CVD). The aim of this study was to assess the potential impact of a family history of metabolic syndrome (fhMetS) on the risk of metabolic disorders (abnormal body mass, lipid profile, glucose metabolism, insulin resistance, and blood pressure) in healthy young individuals. We studied CVD risk factors in 90 healthy volunteers, aged 27-39 years; of these, 78 had fhMetS and 12 were without fhMetS (control group). Fasting serum lipids, glucose, and insulin levels were assayed, and anthropometric parameters and blood pressure using, an ambulatory blood pressure monitoring system, were measured. Nutritional and physical activity habits were assessed. Despite similar nutritional and physical activity habits, abnormal body mass was found in 53.2% of the fhMetS participants and 46.1% of the control participants (p = 0.54). The occurrence of obesity was 19.4% and 0%, respectively (p = 0.69). Compared to the control participants, fhMetS was associated with significantly higher total cholesterol (5.46 mmol/L vs. 4.69 mmol/L, p < 0.030), low-density lipoprotein cholesterol ( 3.28 mmol/L vs. 2.90 mmol/L, p < 0.032), and non-high-density lipoprotein cholesterol ( 3.74 mmol/L vs. 3.25 mmol/L, p < 0.016) levels, in addition to lower fasting glucose levels ( 4.51 mmol/L vs. 4.81 mmol/L, p < 0.042). A positive correlation between fasting glucose and insulin levels (r = 0.28; p < 0.015) was detected in the fhMetS participants. Higher mean daytime systolic blood pressure (121.5 mmHg vs. 113.3 mmHg, p < 0.035), mean daytime diastolic blood pressure ( 79.0 mmHg vs. 74.5 mmHg, p < 0.045), and mean nighttime diastolic blood pressure ( 64.0 mmHg vs. 59.5 mmHg, p < 0.019) were observed in the fhMetS group. More than 50% of the fhMetS participants had excess weight or a lipid disorder, which may indicate an increased risk of cardiovascular disease and the need for regular ambulatory

In order to evaluate physiological characteristics in young male ballet dancers, 27 boys (aged 9 to 16 years) who participated in a boys' dance course during the Kuopio Dance and Music Festival in June 1988 were studied. In general, the boys had started dancing at the age of 8.6 years and had been training for 4.1 years. They had, on average, three dancing sessions per week and the mean time spent on dancing was four hours per week. In the study, some anthropometric measurements were taken, the maximal oxygen uptake (VO2 max) was measured by a cycle ergometer test and the explosive strength and the mechanical power of lower extremities were evaluated by a jumping test. The results indicate that boys who train in ballet are in general moderately lean, have relatively small body size and a high degree of flexibility. The younger boys especially have only moderate aerobic power, but both explosive strength and mechanical power in leg muscles are good in ballet trained boys. PMID:2630002

Objective: The primary aim of this article is to assess young dirvers' gender differences in the associations between substance use/environmental influences and high-risk driving behavior. Method: We determine the association of 12th-grade self-reported substance use/environmental influences with high-risk driving behavior as quantified by the number of offenses, serious offenses, crashes, and single-vehicle crashes on state driving records during subjects' (N = 3,607; 51% male) first 4 years of licensure. Results: The associations between high-risk driving and substance use/environmental influences were generally stronger among women than among men. When matched by substance-use profiles, women had fewer risky-driving incidents than men. Conclusions: The results indicate that young women who exhibit high-risk driving behavior deviate more from the general population of young women with respect to alcohol use, alcohol misuse, and marijuana use than high-risk-driving young men differ from other young men. In addition, findings indicate that even if young men and women were to eventually have equal levels of substance use, women would likely retain their lower-risk driving profiles. These findings suggest the need for (1) future research to understand the differential associations, and (2) prevention programs that consider these gender differences. PMID:16562407

[The profile of neonaticide mothers in legal expertise].

PubMed

Vellut, N; Simmat-Durand, L; Tursz, A

2013-10-01

Neonaticide is the term used to refer to the killing of newborn infants within the first 24 hours of life. A recent study conducted by Inserm Unit 750 found a frequency of 2.1 cases of neonaticide for 100,000 births in France. The persistence of these crimes raises serious issues, and scientists have attempted to explain this by the profile of neonaticidal mothers: young, or even teenage, single, primiparous, and socially deprived. The present study sought to question this profile, and to suggest a new profile for neonaticidal mothers. This retrospective study over the years 1996-2000 comprised 32 cases of neonaticide perpetrated in three French regions. Seventeen solved cases of these 32 cases generated 54 documents by expert consultants, mainly psychiatric and psychological expertise, studied and analysed here using Modalisa software for quantitative analyses and Nvivo software for qualitative data. No single socio-demographic profile was observed. The mothers were in contrasting situations at the time of the event. There were few psychotic profiles. The other psychopathological disturbances detected were very often related to the event. The most surprising feature in the expert reports describing the neonaticidal mothers was the existence of what we have termed "descriptive absent-factors". These mothers had not experienced major trauma in childhood such as the death of persons close or foster care. They were not living in an environment of family violence. They did not exhibit addictive or self-harm behaviour. Their parents before them had similar profiles, except three cases of alcoholism. Their parentage, and that of the infants, was not an issue. The most widely described personality features were immaturity, dependency on others, withdrawal, inhibition, emptiness, lack of affectivity, non-expressiveness, and devaluation of self-image. The very impoverished relational environment of these mothers also appears in the expertise data. Their affective and

[Physical activity, dietary habits and plasma lipoproteins in young men and women].

PubMed

Malara, Marzena; Lutosławska, Grazyna

2010-01-01

There are studies suggesting that in young women strenuous physical activity and inadequate daily energy intake cause unfavorable changes in lipoprotein profile. However until know data concerning this issue are contradictory, possibly due to small number of participants. This study aimed at evaluation of lipoprotein profile in young men and women with different weekly physical activity together with their dietary habits. A total of 202 subjects volunteered to participate of the study--54 female and 56 male students of physical education and 46 female and 49 male students representing other specialization. Daily energy and macronutrient intakes were assessed using FOOD 2 computer program. Plasma TG, TC and HDL-C were assayed colorimetically using Randox commercial kits (Great Britain). It has been demonstrated that high physical activity adversely affects lipoprotein profile in young women characterized by higher TC and LDL-C in comparison with women with low physical activity and with men with high physical activity. The effect of high physical activity on plasma lipoproteins is equivocal. Active men are characterized by higher HDL, but also by higher frequency of unfavorable plasma TC and similar frequency of unfavorable plasma LDL-C C as compared with their less active counterparts. The mean daily energy intake in highly active men and women covered 82% and 72.2% recommended intake, respectively. It seems feasible that in both sexes high physical activity and inadequate energy intake brings about unfavorable changes in plasma lipoproteins.

Although early-stage affective disorders are associated with both cognitive dysfunction and sleep-wake disruptions, relationships between these factors have not been specifically examined in young adults. Sleep and circadian rhythm disturbances in those with affective disorders are considerably heterogeneous, and may not relate to cognitive dysfunction in a simple linear fashion. This study aimed to characterise profiles of sleep and circadian disturbance in young people with affective disorders and examine associations between these profiles and cognitive performance. Actigraphy monitoring was completed in 152 young people (16-30 years; 66% female) with primary diagnoses of affective disorders, and 69 healthy controls (18-30 years; 57% female). Patients also underwent detailed neuropsychological assessment. Actigraphy data were processed to estimate both sleep and circadian parameters. Overall neuropsychological performance in patients was poor on tasks relating to mental flexibility and visual memory. Two hierarchical cluster analyses identified three distinct patient groups based on sleep variables and three based on circadian variables. Sleep clusters included a 'long sleep' cluster, a 'disrupted sleep' cluster, and a 'delayed and disrupted sleep' cluster. Circadian clusters included a 'strong circadian' cluster, a 'weak circadian' cluster, and a 'delayed circadian' cluster. Medication use differed between clusters. The 'long sleep' cluster displayed significantly worse visual memory performance compared to the 'disrupted sleep' cluster. No other cognitive functions differed between clusters. These results highlight the heterogeneity of sleep and circadian profiles in young people with affective disorders, and provide preliminary evidence in support of a relationship between sleep and visual memory, which may be mediated by use of antipsychotic medication. These findings have implications for the personalisation of treatments and improvement of functioning in

Association between interleukin-6 receptor gene variations and atherosclerotic lipid profiles among young adolescents in Taiwan

PubMed Central

2011-01-01

Background To analyze the potential genetic associations between four polymorphisms of interleukin-6 receptor (IL-6R) gene and atherosclerotic lipid profiles among young adolescents in Taiwan. Methods Using data from the Taipei Children Heart Study-II - a cross-sectional survey in 2003. After multi-stage sampling, we selected 418 boys and 441 girls with an average age of 13.1 years. We genotyped the subjects for four IL-6R gene polymorphisms (rs4845617 G/A, rs4845623 A/G, rs8192284 A/C, and rs2229238 C/T) using a TaqMan 5' nuclease assay. Lipid profiles, including total cholesterol (CHOL), triglycerides (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) were measured using standard methods. We also calculated CHOL/HDL-C ratio, LDL-C/HDL-C ratio, and TG/HDL-C ratio as atherosclerotic indexes. Results IL-6R rs8192284 A/C and rs2229238 C/T variants showed strong associations with high TG (additive model, OR = 1.58, 95%CI: 1.05-2.37; OR = 1.55, 95%CI: 1.04-2.29, respectively), low HDL-C (additive model, OR = 1.57, 95%CI: 1.03-2.39; OR = 1.68, 95%CI: 1.12-2.52, respectively), and high CHOL/HDL-C (additive model, OR = 1.68, 95%CI: 1.08-2.61, OR = 1.82, 95%CI: 1.18-2.79, respectively) in girls. We inferred five common haplotypes using rs4845617 G/A, rs4845623 A/G, and rs2229238 C/T (GAC, GAT, GGC, AAC, and AAT). In girls, the AAT haplotype was associated with a significant risk of high TG, low HDL-C, high CHOL/HDL-C, and abnormal lipid levels (high TG or low HDL-C) when compared with the GAC haplotype (OR range = 3.08-4.40, all p < 0.05). Conclusion The IL-6R rs8192284 A/C and rs2229238 C/T variants are associated with dyslipidemia in girls, but not in boys. The AAT haplotype of the IL-6R gene (rs4845617 G/A, rs4845623 A/G, and rs2229238 C/T) may play an important role in the pathogenesis of dyslipidemia and atherosclerosis in girls. PMID:21835044

Young people who have experienced homelessness, foster care, or poverty are among the most disadvantaged in society. This review examines whether young people who have these experiences differ from their non-disadvantaged peers with respect to their cognitive skills and abilities, and whether cognitive profiles differ between these three groups. Three electronic databases were systematically searched for articles published between 1 January 1995 and 1 February 2015 on cognitive functioning among young people aged 15 to 24 years who have experienced homelessness, foster care, or poverty. Articles were screened using pre-determined inclusion criteria, then the data were extracted, and its quality assessed. A total of 31 studies were included. Compared to non-disadvantaged youth or published norms, cognitive performance was generally found to be impaired in young people who had experienced homelessness, foster care, or poverty. A common area of difficulty across all groups is working memory. General cognitive functioning, attention, and executive function deficits are shared by the homeless and poverty groups. Creativity emerges as a potential strength for homeless young people. The cognitive functioning of young people with experiences of impermanent housing and poverty has been relatively neglected and more research is needed to further establish cognitive profiles and replicate the findings reviewed here. As some aspects of cognitive functioning may show improvement with training, these could represent a target for intervention.

2012-01-01

The aim of this research was to develop a path-flow analysis model to highlight the relationships between buoyancy and prone gliding tests and some selected anthropometrical and biomechanical variables. Thirty-eight young male swimmers (12.97 ± 1.05 years old) with several competitive levels were evaluated. It were assessed the body mass, height, fat mass, body surface area, vertical buoyancy, prone gliding after wall push-off, stroke length, stroke frequency and velocity after a maximal 25 [m] swim. The confirmatory model included the body mass, height, fat mass, prone gliding test, stroke length, stroke frequency and velocity. All theoretical paths were verified except for the vertical buoyancy test that did not present any relationship with anthropometrical and biomechanical variables nor with the prone gliding test. The good-of-fit from the confirmatory path-flow model, assessed with the standardized root mean square residuals (SRMR), is considered as being close to the cut-off value, but even so not suitable of the theory (SRMR = 0.11). As a conclusion, vertical buoyancy and prone gliding tests are not the best techniques to assess the swimmer’s hydrostatic and hydrodynamic profile, respectively. PMID:23486528

We investigated the musculoskeletal health profile of elite female football players (ET) in comparison to untrained (UT) young women subjected to 16 weeks of football training (2 × 1 h per week). DXA scans, blood sampling, sprint testing and Flamingo postural balance testing were carried out for 27 Danish national team players and 28 untrained women, with eight women being tested after training. At baseline total BMD and BMC were 13% (1.305 ± 0.050 versus 1.159 ± 0.056 g · cm(-2)) and 23% (3047 ± 235 versus 2477 ± 526 g) higher (P <0.001) and leg BMD and BMC were 24 and 28% higher (P <0.01) in ET than in UT. Resting plasma osteocalcin was 45% higher in ET than in UT (28.8 ± 10.9 versus 19.9 ± 9.9 µg · L(-1), P <0.05). Total lean body mass was 14% higher (50.4 ± 3.3 versus 44.3 ± 4.0 kg) in ET compared with UT, with no difference in total body mass. The number of Flamingo test falls was 56-63% less (P <0.01) and 30 m sprinting speed was 31% faster (P <0.001) in ET than UT. After 16 weeks of football training for UT, lean body mass increased by 1.4 ± 0.5 kg and the number of left leg falls decreased by 29% (P <0.05). No significant changes occurred in BMD or BMC, but plasma osteocalcin increased (P <0.05) by 37%. In summary, elite women footballers have an impressive musculoskeletal health profile compared with untrained controls, but short-term football training seems to reduce the risk of falls and increase bone formation.

School-readiness profiles of children with language impairment: linkages to home and classroom experiences.

2014-01-01

This study represents an effort to advance our understanding of the nature of school readiness among children with language impairment (LI), a population of children acknowledged to be at risk of poor academic achievement. The academic, social-emotional, and behavioural competencies with which children arrive at kindergarten affect the nature of their future educational experiences, and their overall academic achievement. To examine whether there are reliable profiles that characterize children with LI just prior to kindergarten entrance, and the extent to which profile membership is associated with characteristics of children's homes and preschool experiences. Questions addressed were twofold: (1) To what extent are there reliable profiles of children with LI with respect to their school readiness? (2) To what extent is children's profile membership associated with characteristics of their homes and preschool classrooms? Participants were 136 children with LI from early childhood special education classrooms. We utilized latent class analysis (LCA) to classify individuals into profiles based on individual responses on school readiness measures. We then used multilevel hierarchical generalized linear models to examine the relations between profile membership and children's home/classroom experiences. LCA analyses revealed that a four-profile solution was the most appropriate fit for the data and that classroom experiences were predictive of these profiles, such that children in classrooms with more instructional/emotional support were more likely to be placed in profiles characterized by higher school readiness skills. These results suggest that the school readiness profiles of young children with LI are associated with the quality of children's classroom experiences, and that high-quality classroom experiences can be influential for ensuring that young children with LI arrive in kindergarten ready to learn. © 2014 Royal College of Speech and Language Therapists.

2015-03-01

This study is divided into three sequential stages: identification of fitness and game performance profiles (individual player performance), an assessment of the relationship between these profiles, and an assessment of the relationship between individual player profiles and team performance during play (in championship performance). The overall study sample comprised 525 (19 teams) female volleyball players aged 12-16 years and a subsample (N.=43) used to examine study aims one and two was selected from overall sample. Anthropometric, fitness and individual player performance (actual game) data were collected in the subsample. These data were analyzed through clustering methods, ANOVA and independence chi-square test. Then, we investigated whether the proportion of players with the highest individual player performance profile might predict a team's results in the championship. Cluster analysis identified three volleyball fitness profiles (high, medium, and low) and two individual player performance profiles (high and low). The results showed a relationship between both types of profile (fitness and individual player performance). Then, linear regression revealed a moderate relationship between the number of players with a high volleyball fitness profile and a team's results in the championship (R2=0.23). The current study findings may enable coaches and trainers to manage training programs more efficiently in order to obtain tailor-made training, identify volleyball-specific physical fitness training requirements and reach better results during competitions.

High Aerobic Capacity Mitigates Changes in the Plasma Metabolomic Profile Associated with Aging.

Advancing age is associated with declines in maximal oxygen consumption. Declines in aerobic capacity not only contribute to the aging process but also are an independent risk factor for morbidity, cardiovascular disease, and all-cause mortality. Although statistically convincing, the relationships between aerobic capacity, aging, and disease risk remain largely unresolved. To this end, we employed sensitive, system-based metabolomics approach to determine whether enhanced aerobic capacity could mitigate some of the changes seen in the plasma metabolomic profile associated with aging. Metabolomic profiles of plasma samples obtained from young (13 month) and old (26 month) rats bred for low (LCR) or high (HCR) running capacity using proton nuclear magnetic resonance spectroscopy ( 1 H NMR) were examined. Results demonstrated strong profile separation in old and low aerobic capacity rats, whereas young and high aerobic capacity rat models were less predictive. Significantly differential metabolites between the groups include taurine, acetone, valine, and trimethylamine-N-oxide among other metabolites, specifically citrate, succinate, isovalerate, and proline, were differentially increased in older HCR animals compared with their younger counterparts. When interactions between age and aerobic capacity were examined, results demonstrated that enhanced aerobic capacity could mitigate some but not all age-associated alterations in the metabolomic profile.

Mapping the Outer Edge of the Young Stellar Cluster in the Galactic Center

We present new near-infrared spectroscopic observations of the outer edges of the young stellar cluster around the supermassive black hole at the Galactic center. The observations show a break in the surface density profile of young stars at ˜13″ (0.52 pc). These observations spectroscopically confirm previous suggestions of a break based on photometry. Using Gemini North's Near-Infrared Integral Field Spectrometer, we are able to detect and separate early- and late-type stars with a 75% completeness at {K}{{s}}=15.5. We sample a region with radii between 7″ and 23″ (0.28-0.92 pc) from Sgr A* and present new spectral classifications of 144 stars brighter than {K}{{s}}=15.5, where 140 stars are late-type (\\gt 1 Gyr) and only four stars are early-type (young, 4-6 Myr). A broken power-law fit of the early-type surface density matches well with our data and previously published values. The projected surface density of late-type stars is also measured and found to be consistent with previous results. We find that the observed early-type surface-density profile is inconsistent with the theory of young stars originating from a tightly bound infalling cluster, as no significant trail of young stars is found at radii above 13″. We also note that either a simple disk instability criterion or a cloud-cloud collision could explain the location of the outer edge, though we lack information to make conclusive remarks on either alternative. If this break in surface density represents an edge to the young stellar cluster, it would set an important scale for the most recent episode of star formation at the Galactic center.

Ground-based microwave radiometry to determine stratospheric and mesospheric ozone profiles

NASA Astrophysics Data System (ADS)

Lobsiger, E.

1987-05-01

From April 1984 to April 1985 a microwave radiometer was operated at Bern measuring the thermal emission of the rotational ozone transition at 142.2 GHz to determine stratospheric and mesospheric ozone abundances in the range 25-75 km altitude. From a total of 334 retrieved daytime profiles, monthly mean ozone partial pressures for Umkehr layers 6-10 were calculated. On this basis ozone variations compare favorably with Umkehr data from the nearby Arosa station and with a monthly zonal mean model compiled from satellite data by Keating and Young (1985). From the microwave data, an annual mean ozone distribution was determined. The method retrieves somewhat larger ozone volume mixing ratios between 25 and 30 km altitude. For the rest of the measurement range of the sensor there is good agreement with 20-year annual mean ozone values from Arosa, with the Krueger and Minzner profile and with the respective annual mean data given by Keating and Young.

Profile and distribution of glucosinolates (GLS) were detected in plant tissues of horseradish at different developmental stages: beginning of vegetative re-growth, flowering and silique formation. The GLS profile varied widely in the different tissues: we identified 17 GLS in roots and sprouts, one of which was not previously characterized in horseradish, i.e. the 2(S)-hydroxy-2-phenylethyl-GLS (glucobarbarin) and/or 2(R)-hydroxy-2-phenylethyl-GLS (epiglucobarbarin), 11 already found in the roots, including the putative 2-methylsulfonyl-oxo-ethyl-GLS, and 5 previously recognized only in the sprouts. Fifteen of those GLS were also identified in young and cauline leaves, 12 in the mature leaves and 13 in the inflorescences. No difference in GLS profile was observed in plant among the phenological stages. Differences in concentrations of GLS, quantified as desulfated, were found in plant. At the beginning of vegetative re-growth, sprouts while showing the same profile of the roots were much richer in GLS having the highest total GLS concentrations (117.5 and 7.7μmolg(-1) dry weight in sprouts and roots, respectively). During flowering and silique forming stages, the roots still maintained lower amount of total GLS (7.4μmolg(-1) of dry weight, on average) with respect to the epigeous tissues, in which mature and young leaves showed the highest total concentrations (70.5 and 73.8μmolg(-1) of dry weight on average, respectively). Regardless of the phenological stages, the aliphatic GLS were always predominant in all tissues (95%) followed by indolic (2.6%) and benzenic (2.4%) GLS. Sinigrin contributed more than 90% of the total GLS concentration. Aliphatic GLS concentrations were much higher in the epigeous tissues, particularly in the mature and young leaves, while benzenic and indolic GLS concentrations were higher in the roots. Through the phenological stages, GLS concentration increased in young and mature leaves and decreased in cauline leaves and inflorescences

There is relevant between individual variability in paracetamol clearance in young women. In this pooled study, we focused on the population pharmacokinetic profile of intravenous paracetamol metabolism and its covariates in young women. Population PK parameters using non-linear mixed effect modelling were estimated in a pooled dataset of plasma and urine PK studies in 69 young women [47 at delivery, 8/47 again 10-15 weeks after delivery (early postpartum), and 7/8 again 1 year after delivery (late postpartum), 22 healthy female volunteers with or without oral contraceptives]. Population PK parameters were estimated based on 815 plasma samples and 101 urine collections. Compared to healthy female volunteers (reference group) not on oral contraceptives, being at delivery was the most significant covariate for clearance to paracetamol glucuronide (Factor = 2.03), while women in early postpartum had decreased paracetamol glucuronidation clearance (Factor = 0.55). Women on contraceptives showed increased paracetamol glucuronidation clearance (Factor = 1.46). The oestradiol level did not further affect this model. Being at delivery did not prove significant for clearance to paracetamol sulphate, but was higher in pregnant women who delivered preterm (<37 weeks, Factor = 1.34) compared to term delivery and non-pregnant women. Finally, clearance of unchanged paracetamol was dependent on urine flow rate. Compared to healthy female volunteers not on oral contraceptives, urine paracetamol glucuronidation elimination in young women is affected by pregnancy (higher), early postpartum (lower) or exposure to oral contraceptives (higher), resulting in at least a two fold variability in paracetamol clearance in young women.

For a long time it has been postulated that diet may influence estrogen metabolism and in this way affect breast cancer risk. In order to investigate possible effects of variations of dietary fiber intake on estrogen metabolism, the urinary estrogen profile (13 estrogens), including the catecholestrogens, was determined in one 72-h summer and one winter sample collected in the midfollicular phase of the menstrual cycle by 11 lactovegetarian and 12 omnivorous young Finnish women. Urinary estrogens were purified by ion-exchange chromatography and the quantitative determination was carried out by capillary gas chromatography-mass spectrometry. Detailed records of the subjects' diet during one 5-day period in summer and one in winter were obtained and dietary fiber intake calculated. The mean difference with regard to intake of total fiber in the two dietary groups was 3 g/day in the summer (not significant) and 5 g/day in the winter (P less than 0.05), the mean (geometric) consumption being 23 and 19 g/day by the vegetarian and omnivorous women, respectively. Within the groups we found seasonal variation in fiber intake only for the omnivorous women. During winter, compared to summer, the omnivorous women consumed significantly less grain (P less than 0.001), vegetable (P less than 0.02) and total fiber (P less than 0.02). The excretion of 13 estrogens was remarkably constant in the omnivoric group but a significant seasonal variation of total and individual catecholestrogens and of estrone was observed in the vegetarians (P less than 0.05-0.005). The quantitatively most important estrogen was 2-hydroxyestrone, followed by estrone, estriol, 2-hydroxyestradiol, 4-hydroxyestrone and estradiol, the three latter being excreted in similar amounts. Between the dietary groups there were no significant differences in excretion of total or individual urinary estrogens in any season or between the mean values for both seasons. However, numerous significant (P less than 0

Transitioning from paediatric to adult care can be a particularly challenging time for young people with epilepsy and research has shown that there are a range of factors which may influence a young person's ability to successfully cope with this difficult time. The following study aimed to explore the psychosocial characteristics of this transitioning population, as well as investigate how knowledgeable the young person and their parent/carer are of their own condition throughout transition. Young people with epilepsy were recruited from two specialist epilepsy clinics in the North West and allocated to one of three groups; Group 1 pre-transition, Group 2 transitioning, and Group 3 post-transition. Results found that the young person's knowledge increased significantly throughout transition, whilst parent/carer's knowledge decreased. In addition, anxiety was found to be significantly lower in Group 2 (transitioning group) compared to Group 1 (pre-transition) and Group 3 (post-transition) and a number of significant gender differences were also identified across the groups. The study highlights the importance of considering all relevant psychosocial factors, such as anxiety, gender and the degree of knowledge the individual holds of their own condition during the transition process in order to develop psycho-educational programmes and transition pathways.

Divorce is a part of my life... resilience, survival, and vulnerability: young adults' perception of the implications of parental divorce.

PubMed

Eldar-Avidan, Dorit; Haj-Yahia, Muhammad M; Greenbaum, Charles W

2009-01-01

A qualitative study among 22 young adults (20-25 years old) whose parents divorced during their childhood was conducted in Israel, using semi-structured, in-depth, open-ended interviews. Qualitative data analysis led to identification of three profiles, aiming at a grounded theoretical conceptualization. Three core themes were identified: the centrality of the family; short- and long-term implications of parental divorce and its relations to supportive coping resources; and perspective at young adulthood. Further analysis led to typifying participants by three profiles, which represent the grounded theoretical conceptualizations: resilience, survival, and vulnerability. The most prominent difference among the profiles was the relationships between participants and their parents, and their perception of ongoing parental responsibility. A thorough discussion of the results and their implications for future research, theory development, and practice are presented.

Young men in 'crisis': attending to the language of teenage boys' distress.

PubMed

McQueen, Carolyn; Henwood, Karen

2002-11-01

The last two decades have seen a changing profile of young male mental health in Britain, including increased suicidal and parasuicidal behaviours. For mental health professionals to respond effectively and appropriately to meet these changing needs there needs to be further theorising and development of knowledge of young men's psychological processes and, in particular, how they make sense of their experiences within the cultural context of their lives. By drawing upon contemporary theories of subjectivities, this paper attempts to begin to address some of these issues. It looks in detail at two young men's accounts of their experiences of mental health problems. By using narrative, thematic and discourse analyses, the authors consider the cultural concepts the young men draw upon, and the language they use to voice their distress. The paper focuses on how gender and traditional masculinities constrain and influence the young men's narratives within the context of their individual life-histories and how these may become problematic for their mental health. The analyses provide a contemporary language-sensitive and culturally-sensitive reading of the young men's accounts of mental distress. It highlights how young men may talk about their distress in ways that are not immediately recognisable and extends the knowledge of the contemporary discourses used by young men in British society today. The implications for male subjectivities and mental health and therapeutic engagement are discussed.

Social inequalities in health information seeking among young adults in Montreal.

Over their lifecourse, young adults develop different skills and preferences in relationship to the information sources they seek when having questions about health. Health information seeking behaviour (HISB) includes multiple, unequally accessed sources; yet most studies have focused on single sources and did not examine HISB's association with social inequalities. This study explores 'multiple-source' profiles and their association with socioeconomic characteristics. We analyzed cross-sectional data from the Interdisciplinary Study of Inequalities in Smoking involving 2093 young adults recruited in Montreal, Canada, in 2011-2012. We used latent class analysis to create profiles based on responses to questions regarding whether participants sought health professionals, family, friends or the Internet when having questions about health. Using multinomial logistic regression, we examined the associations between profiles and economic, social and cultural capital indicators: financial difficulties and transportation means, friend satisfaction and network size, and individual, mother's, and father's education. Five profiles were found: 'all sources' (42%), 'health professional centred' (29%), 'family only' (14%), 'Internet centred' (14%) and 'no sources' (2%). Participants with a larger social network and higher friend satisfaction were more likely to be in the 'all sources' group. Participants who experienced financial difficulties and completed college/university were less likely to be in the 'family only' group; those whose mother had completed college/university were more likely to be in this group. Our findings point to the importance of considering multiple sources to study HISB, especially when the capacity to seek multiple sources is unequally distributed. Scholars should acknowledge HISB's implications for health inequalities.

Time-of-day effects on voice range profile performance were investigated in 20 vocally healthy untrained women between the ages of 18 and 35 years. Each subject produced two complete voice range profiles: one in the morning and one in the evening, about 36 hours apart. The order of morning and evening trials was counterbalanced across subjects. Dependent variables were (1) average minimum and average maximum intensity, (2) Voice range profile area and (3) center of gravity (median semitone pitch and median intensity). In this study, the results failed to reveal any clear evidence of time-of-day effects on voice range profile performance, for any of the dependent variables. However, a reliable interaction of time-of-day and trial order was obtained for average minimum intensity. Investigation of other subject populations, in particular trained vocalists or those with laryngeal lesions, is required for any generalization of the results.

Detection and cultivation of indigenous microorganisms in Mesozoic claystone core samples from the Opalinus Clay Formation (Mont Terri Rock Laboratory)

Mauclaire, L.; McKenzie, J. A.; Schwyn, B.; Bossart, P.

Although microorganisms have been isolated from various deep-subsurface environments, the persistence of microbial activity in claystones buried to great depths and on geological time scales has been poorly studied. The presence of in-situ microbial life in the Opalinus Clay Formation (Mesozoic claystone, 170 million years old) at the Mont Terri Rock Laboratory, Canton Jura, Switzerland was investigated. Opalinus Clay is a host rock candidate for a radioactive waste repository. Particle tracer tests demonstrated the uncontaminated nature of the cored samples, showing their suitability for microbiological investigations. To determine whether microorganisms are a consistent and characteristic component of the Opalinus Clay Formation, two approaches were used: (i) the cultivation of indigenous micoorganisms focusing mainly on the cultivation of sulfate-reducing bacteria, and (ii) the direct detection of molecular biomarkers of bacteria. The goal of the first set of experiments was to assess the presence of cultivable microorganisms within the Opalinus Clay Formation. After few months of incubation, the number of cell ranged from 0.1 to 2 × 10 3 cells ml -1 media. The microorganisms were actively growing as confirmed by the observation of dividing cells, and detection of traces of sulfide. To avoid cultivation bias, quantification of molecular biomarkers (phospholipid fatty acids) was used to assess the presence of autochthonous microorganisms. These molecules are good indicators of the presence of living cells. The Opalinus Clay contained on average 64 ng of PLFA g -1 dry claystone. The detected microbial community comprises mainly Gram-negative anaerobic bacteria as indicated by the ratio of iso/anteiso phospholipids (about 2) and the detection of large amount of β-hydroxy substituted fatty acids. The PLFA composition reveals the presence of specific functional groups of microorganisms in particular sulfate-reducing bacteria ( Desulfovibrio, Desulfobulbus, and

The purpose of this study was to evaluate whether the mRNA expression profiles of three genes (PRMT1, DDAH2 and NOS3) are related to ADMA metabolism and signalling, and the potential relationships with anthropometrical, biochemical, lifestyle and inflammatory indicators in healthy young adults. An emphasis on the putative effect of different mRNA expression on cardiovascular risk-related features was paid. Anthropometrical measurements as well as lifestyle features were analyzed in 120 healthy young adults. Fasting blood samples were collected for the measurement of glucose and lipid profiles as well as the concentrations of selected inflammatory markers. Profiles of mRNA expression were assessed for PRMT1, DDAH2 and NOS3 genes from peripheral blood mononuclear cells. Regarding inflammatory biomarkers, DDAH2 was inversely associated with IL-6 and TNF-alpha. Moreover, subjects in the highest quintile of DDAH2 mRNA expression showed a reduced risk to have higher values of waist circumference, and to be more prone to show higher values of HDL-c. Interestingly, DDAH2 gene expression seemed to be related with some anthropometrical, biochemical, lifestyle and inflammatory indicators linked to cardiovascular risk in apparently healthy young adults, emerging as a potential disease marker.

The aim of this study was to build a detailed, integrative profile of the correlates of young adults' feelings of loneliness, in terms of their current health and functioning and their childhood experiences and circumstances. Data were drawn from the Environmental Risk Longitudinal Twin Study, a birth cohort of 2232 individuals born in England and Wales in 1994 and 1995. Loneliness was measured when participants were aged 18. Regression analyses were used to test concurrent associations between loneliness and health and functioning in young adulthood. Longitudinal analyses were conducted to examine childhood factors associated with young adult loneliness. Lonelier young adults were more likely to experience mental health problems, to engage in physical health risk behaviours, and to use more negative strategies to cope with stress. They were less confident in their employment prospects and were more likely to be out of work. Lonelier young adults were, as children, more likely to have had mental health difficulties and to have experienced bullying and social isolation. Loneliness was evenly distributed across genders and socioeconomic backgrounds. Young adults' experience of loneliness co-occurs with a diverse range of problems, with potential implications for health in later life. The findings underscore the importance of early intervention to prevent lonely young adults from being trapped in loneliness as they age.

The aim of this study was to examine prelinguistic vocal development in very young cochlear implant recipients. A prospective longitudinal research design was used to observe the sequence and time-course of vocal development in seven children who were implanted between 10 and 36 months of age. Speech samples were collected twice before implant activation and on a monthly basis thereafter for up to 2 years. Children’s vocalizations were classified according to the levels of the Stark Assessment of Early Vocal Development- Revised (SAEVD-R; Nathani, Ertmer, & Stark, in press). The main findings were (a) six of seven children made advancements in vocal development after implantation, (b) children implanted between 12 and 36 months progressed through SAEVD-R levels in the predicted sequence whereas a child implanted at a younger age showed a different sequence, (c) milestones in vocal development were often achieved with fewer months of hearing experience than observed in typically developing infants and appeared to be influenced by age at implantation, and (d) in general, children implanted at younger ages completed vocal development at younger chronological ages than those implanted later in life. Clinical indicators of benefit from implant use were also identified. PMID:17463237

The aim of this article has been to classify swimmers based on kinematics, hydrodynamics, and anthropometrics. Sixty-seven young swimmers made a maximal 25 m front-crawl to measure with a speedometer the swimming velocity (v), speed-fluctuation (dv) and dv normalized to v (dv/v). Another two 25 m bouts with and without carrying a perturbation device were made to estimate active drag coefficient (CDa). Trunk transverse surface area (S) was measured with photogrammetric technique on land and in the hydrodynamic position. Cluster 1 was related to swimmers with a high speed fluctuation (ie, dv and dv/v), cluster 2 with anthropometrics (ie, S) and cluster 3 with a high hydrodynamic profile (ie, CDa). The variable that seems to discriminate better the clusters was the dv/v (F=53.680; P<.001), followed by the dv (F=28.506; P<.001), CDa (F=21.025; P<.001), S (F=6.297; P<.01) and v (F=5.375; P=.01). Stepwise discriminant analysis extracted 2 functions: Function 1 was mainly defined by dv/v and S (74.3% of variance), whereas function 2 was mainly defined by CDa (25.7% of variance). It can be concluded that kinematics, hydrodynamics and anthropometrics are determinant domains in which to classify and characterize young swimmers' profiles.

In this open-label, single-center, pharmacokinetic study of repaglinide, 12 healthy volunteers (6 men, 6 women) were enrolled in each of 2 groups (total, 24 volunteers). One group consisted of young adult subjects (18 to 40 years), and the other group consisted of elderly subjects (> or = 65 years). On day 1, after a 10-hour fast, all 24 subjects received a single 2-mg dose of repaglinide. Starting on day 2 and continuing for 7 days, subjects received a 2-mg dose of repaglinide 15 minutes before each of 3 meals. On day 9, subjects received a single 2-mg dose of repaglinide. Pharmacokinetic profiles, including area under the curve, maximum concentration (Cmax), time to Cmax, and half-life, were determined at completion of the single-dose and multiple-dose regimens (days 1 and 9, respectively). Trough repaglinide values were collected on days 2 through 7 to assess steady state. The single-dose and multiple-dose pharmacokinetic variables of serum repaglinide were not significantly different between young adult and elderly subjects. Repaglinide was well tolerated in both groups. Hypoglycemic events occurred in 5 young adult and 5 elderly subjects. This study demonstrates that the pharmacokinetics of repaglinide are similar in healthy young adult and elderly subjects.

The Middle East represents an attractive area for young individuals to seek employment, where they are exposed to numerous environmental conditions. The pursuit of a better standard of living has driven hundreds to the Middle East over the recent decades. This influx has also resulted in a predisposition to premature coronary artery disease (CAD). The aim of this study was to provide an overview of the risk factors in patients younger than 45 years, presenting with acute myocardial infarction (AMI). Out of the 148 patients analyzed, 137 were males and 11 females. 119 were from South Asia and 29 were Arabs. Their mean age was 36 ± 4.2 years. Smoking was the most prevalent risk factor in both groups at 67.6%. This was followed by hypertension, family history of CAD, hyperlipidemia and Diabetes mellitus. There was no significant difference in the clinical risk factor profile between these two groups. ST elevation myocardial infarction (STEMI) was noted in 67.6%, while 32.4% patients suffered a Non ST elevation myocardial infarction (NSTEMI). 84.5% received coronary stents, 8.8% had lone thrombus aspiration or balloon angioplasty only, while the rest were treated by conservative medical management or referred for coronary artery bypass surgery. Conclusion: There is no significant difference in the CAD risk profile between young South Asian and Arab patients. Preventive strategies focused on risk factor reduction, especially smoking cessation, should be implemented to protect young adults in the most productive years of their life. PMID:23991352

2016-01-01

Purpose This study assessed the long-term stability and instability of subjective well-being during post-school transition (i.e., transition from adolescence to young adulthood) and evaluated the determinants of transition stability. Methods Using two cohorts from a national representative longitudinal study, the Longitudinal Study of Australian Youth (N = 20991), latent profile analysis and latent transition analysis were conducted to examine transition patterns among subjective well-being profiles for youth from age 17 to 25. Multinomial logistic regressions were conducted to evaluate whether key socio-demographic variables were associated with transition stability. Results We identified: (1) three subjective well-being profiles: Low (30%), Moderate (50%), and High (20%); and (2) three major transition patterns among these subjective well-being profiles: stable, partially-stable, and unstable. The majority of youth had stable transition patterns during the transition from adolescence to adulthood. A large percentage of youth (52%) started low in subjective well-being profile and remained in the low subjective-wellbeing profile. Our examination also revealed gender was the most pronounced indicator for transition stability during this time period, with males more likely to have unstable transition patterns than females. Conclusions Results suggest that different subjective well-being status and transition patterns can be identified in the post-high school transition to adulthood, including unstable transitions. By targeting those groups more vulnerable to transition, mental health promotion and interventions may be delivered more effectively. PMID:27232183

Vitamin D deficiency has been associated with increased risk for cardiovascular disease and anemia. Vitamin D-related changes in lipid profile have been studied extensively but the relationship between vitamin D and lipid metabolism is not completely understood. As both vitamin D and intermittent training may potentially affect iron and lipid metabolism, the aim of the study was to evaluate whether a daily supplementation of vitamin D can modulate the response of hematological and lipid parameters to high-intensity interval training (HIIT) in soccer players. Thirty-six young elite junior soccer players were included in the placebo-controlled, double-blind study. Participants were non-randomly allocated into either a supplemented group (SG, n=20, HIIT and 5,000 IU of vitamin D daily) or placebo group (PG, n=16, HIIT and sunflower oil). Hematological parameters were ascertained before and after the 8-wk training. The change score (post- and pre-training difference) was calculated for each individual and the mean change score (MCS) was compared between SG and PG using the t test and analysis of covariance. There were no differences between SG and PG at baseline. The red and white cell count, hemoglobin, hematocrit, MCHC, ferritin, and HDL-cholesterol changed significantly over the 8-wk HIIT. However, no significant differences in MCS were observed between SG and PG for any variable. A daily vitamin D supplement did not have any impact on alteration in hematological or lipid parameters in young soccer players in the course of high-intensity interval training.

The prevention of addictions in young people is a challenge for Mental and Public Health policies, and requires specific risk-screening tools. Specific personality traits, as assessed using the Substance Use Risk Profile Scale (SURPS), could play a key role in the onset and escalation of substance use. This study aimed to examine (1) measurement invariance across age and gender (2) the effects of age and gender on associations between SURPS scores and the most frequently-consumed substances. Analyses were based on the responses from 5069 participants (aged 14-20 years) from the 2011 ESPAD-France dataset. Substance-use outcomes were experimentation and current frequency of alcohol, tobacco and cannabis use, and drunkenness. Our approach, consisting in analysing measurement and structural invariance and interaction terms, established the stability of (i) SURPS profiles, and (ii) relationships between these scores and substance experimentation and use over a developmental period ranging from mid-adolescence to early adulthood. Measurement invariance across genders was also confirmed despite the absence of scalar invariance for 2 items. Significant interactions between gender and SURPS factors were established, highlighting differential vulnerability, especially concerning Hopelessness and experimentation of alcohol and drunkenness, or Impulsivity and tobacco experimentation. Finally, Anxiety Sensitivity could be protective against substance use, especially for cannabis in girls. Our results suggest the relevance of the SURPS to assess vulnerability towards drug use, and underline the need to consider gender differences in addiction risks. Copyright © 2016 The Authors.

A blood test to detect stroke and its causes would be particularly useful in babies, young children, and patients in intensive care units, and for emergencies when imaging is difficult to obtain or unavailable. Using whole genome microarrays, we first showed specific gene expression profiles in rats 24 hours after ischemic and hemorrhagic stroke, hypoxia, and hypoglycemia. These proof-of-principle studies revealed that groups of genes (called gene profiles) can distinguish ischemic stroke patients from controls 3 hours to 24 hours after the strokes. In addition, gene expression profiles have been developed that distinguish stroke due to large-vessel atherosclerosis from cardioembolic stroke. These profiles will be useful for predicting the causes of cryptogenic stroke. Our results in adults suggest similar diagnostic tools could be developed for children. PMID:21636778

Isometric shoulder strength in young swimmers.

McLaine, Sally J; Ginn, Karen A; Fell, James W; Bird, Marie-Louise

2018-01-01

The prevalence of shoulder pain in young swimmers is high. Shoulder rotation strength and the ratio of internal to external rotation strength have been reported as potential modifiable risk factors associated with shoulder pain. However, relative strength measures in elevated positions, which include flexion and extension, have not been established for the young swimmer. The aim of this study was to establish clinically useful, normative shoulder strength measures and ratios for swimmers (14-20 years) without shoulder pain. Cross-sectional, observational study. Swimmers (N=85) without a recent history of shoulder pain underwent strength testing of shoulder flexion and extension (in 140° abduction); and internal and external rotation (in 90° abduction). Strength tests were performed in supine using a hand-held dynamometer and values normalised to body weight. Descriptive statistics were calculated for strength and strength ratios (flexion:extension and internal:external rotation). Differences between groups (based on gender, history of pain, test and arm dominance) were explored using independent and paired t tests. Normative shoulder strength values and ratios were established for young swimmers. There was a significant difference (p<0.002) in relative strength between males and females for all tests with no differences in strength ratios. Relative strength of the dominant and non-dominant shoulders (except for extension); and for swimmers with and without a history of shoulder pain was not significantly different. A normal shoulder strength profile for the young swimmer has been established which provides a valuable reference for the clinician assessing shoulder strength in this population.

Parental divorce occurred during late childhood to early adolescence; indicators of nonresidential father engagement were assessed during adolescence, and mental health problems and academic achievement of offspring were assessed 9 years later in young adulthood. Three profiles of father engagement were identified in our sample of mainly White, non-Hispanic divorced fathers: Moderate Involvement/Low Conflict, Low Involvement/Moderate Conflict, and High Involvement/High Conflict. Profiles differentially predicted offspring outcomes 9 years later when they were young adults, controlling for quality of the mother-adolescent relationship, mother's remarriage, mother's income, and gender, age, and offspring mental health problems in adolescence. Offspring of fathers characterized as Moderate Involvement/Low Conflict had the highest academic achievement and the lowest number of externalizing problems 9 years later compared to offspring whose fathers had profiles indicating either the highest or lowest levels of involvement but higher levels of conflict. Results indicate that greater paternal psychosocial support and more frequent father-adolescent contact do not outweigh the negative impact of interparental conflict on youth outcomes in the long term. Implications of findings for policy and intervention are discussed.

Sexual identity development is a central task of adolescence and young adulthood and can be especially challenging for sexual minority youth. Recent research has moved from a stage model of identity development in lesbian, gay, and bisexual (LGB) youth to examining identity in a non-linear, multidimensional manner. In addition, although families have been identified as important to youth's identity development, limited research has examined the influence of parental responses to youth's disclosure of their LGB sexual orientation on LGB identity. The current study examined a multidimensional model of LGB identity and its links with parental support and rejection. One hundred and sixty-nine LGB adolescents and young adults (ages 14–24, 56% male, 48% gay, 31% lesbian, 21% bisexual) described themselves on dimensions of LGB identity and reported on parental rejection, sexuality-specific social support, and non-sexuality-specific social support. Using latent profile analysis (LPA), two profiles were identified, indicating that youth experience both affirmed and struggling identities. Results indicated that parental rejection and sexuality-specific social support from families were salient links to LGB identity profile classification, while non-sexuality specific social support was unrelated. Parental rejection and sexuality-specific social support may be important to target in interventions for families to foster affirmed LGB identity development in youth. PMID:22847752

The EXTRAP-T2 reversed field pinch has undergone a significant reconstruction into the new T2R device. This paper reports the first measurements performed with Langmuir probes in the edge region of EXTRAP-T2R. The radial profiles of plasma parameters like electron density and temperature, plasma potential, electrical fields and electrostatic turbulence-driven particle flux are presented. These profiles are interpreted in a momentum balance model where finite Larmor radius losses occur over a distance of about two Larmor radii from the limiter position. The double shear layer of the E×B drift velocity is discussed in terms of the Biglari-Diamond-Terry theory of turbulence decorrelation.

This paper examines the video-based pedagogical practices of Terry (pseudonym), a head coach of a professional junior academy squad. Data were collected through 6 in-depth, semi-structured interviews and 10 field observations of Terry's video-based coaching in situ. Three embracing categories were generated from the data. These demonstrated that Terry's video-based coaching was far from apolitical. Rather, Terry strategically used performance analysis technologies to help fulfil various objectives and outcomes that he understood to be expected of him within the club environment. Kelchtermans' micropolitical perspective, Callero's work addressing role and Groom et al.'s grounded theory were primarily utilised to make sense of Terry's perceptions and actions. The findings point to the value of developing contextually grounded understandings of coaches' uses of video-based performance analysis technology. Doing so could better prepare coaches for this aspect of their coaching practice.

The variability of interstellar atomic lines, sporadically reported in the astronomical literature, has been confirmed both in the case of the nearby hot star δ Ori and the very young and violent star-forming region η Carinae, using high-resolution echelle spectra. The presented variability concerns the intensities and profiles of Na I, K I and Ca II. The time-scale of the above-mentioned variations clearly suggests very local phenomena as their cause. It is important to say that not all interstellar lines vary in unison.

This study was conducted to examine the effects of dietary valine on the physical and flavor characteristics, fatty acid (FA) profile, antioxidant status and Nrf2-dependent antioxidant enzyme gene expression in the muscle of young grass carp (Ctenopharyngodon idella) fed increasing levels of valine (4.3, 8.0, 10.6, 13.1, 16.9 and 19.1 g/kg) for 8 weeks. Compared with the control group, the group fed valine showed improved physical characteristics of fish fillets (increased relative shear force, hydroxyproline, protein and lipid levels and decreased cathepsin B and L activities, as well as cooking loss, were observed). Moreover, valine improved the flavor of young grass carp fillets by increasing the amino acid (AA) concentration in fish muscle (increased aspartic acid, threonine, glutamine, cystine, methionine, leucine, tyrosine, phenylalanine, lysine, histidine, arginine and valine concentrations were observed). Additionally, optimal valine supplementation increased the potential health benefits to humans by decreasing the saturated FA (C15:0 and C16:0) concentration and increasing the unsaturated FA (monounsaturated FAs (MUFAs), such as C16:1, C18:1c+t and C20:1, and polyunsaturated FAs (PUFAs), such as C18:3n-3, C20:2 and C22:6) concentration. In addition, the reduced glutathione (GSH) content and the activities of Cu/Zn superoxide dismutase (SOD1), catalase (CAT) and Selenium-dependent glutathione peroxydase (Se-GPx) increased under valine supplementation (P < 0.05). Furthermore, the SOD1, CAT and Se-GPx mRNA levels increased with dietary valine levels, possibly due to the up-regulation of NF-E2-related factor 2 (Nrf2), target of rapamycin (TOR) and ribosomal protein S6 kinase 1 (S6K1) and the down-regulation of Kelch-like-ECH-associated protein 1 (Keap1) in muscle (P < 0.05). In conclusion, valine improved the physical and flavor characteristics, FA profile, and antioxidant status and regulated the expression of the antioxidant enzyme genes Nrf2, Keap1, TOR

2016-10-01

Since amplified music gained widespread popularity, there has been community concern that leisure-noise exposure may cause hearing loss in adolescents and young adults who would otherwise be free from hearing impairment. Repeated exposure to personal stereo players and music events (e.g., nightclubbing, rock concerts, and music festivals) are of particular concern. The same attention has not been paid to leisure-noise exposure risks for young people with hearing impairment (either present from birth or acquired before adulthood). This article reports on the analysis of a subset of data (leisure participation measures) collected during a large, two-phase study of the hearing health, attitudes, and behaviors of 11- to 35-yr-old Australians conducted by the National Acoustic Laboratories (n = 1,667 hearing threshold level datasets analyzed). The overall aim of the two-phase study was to determine whether a relationship between leisure-noise exposure and hearing loss exists. In the current study, the leisure activity profiles and accumulated ("whole-of-life") noise exposures of young people with (1) hearing impairment and (2) with normal hearing were compared. Cross-sectional cohort study. Hearing impaired (HI) group, n = 125; normal (nonimpaired) hearing (NH) group, n = 296, analyzed in two age-based subsets: adolescents (13- to 17-yr-olds) and young adults (18- to 24-yr-olds). Participant survey. The χ² test was used to identify systematic differences between the leisure profiles and exposure estimates of the HI and NH groups. Whole-of-life noise exposure was estimated by adapting techniques described in ISO 1999. For adolescents, leisure profiles were similar for the two groups and few individuals exceeded the stated risk criterion. For young adults, participation was significantly lower for the HI group for 7 out of 18 leisure activities surveyed. Activity diversity and whole-of-life exposure were also significantly lower for the HI group young adults. A

The purpose of this study was to determine whether distinct latent profiles of religiousness/spirituality exist for ALWH, and if so, are latent profile memberships associated with health-related quality of life (HRQoL). Latent profile analysis of religiosity identified four profiles/groups. Compared to the other three groups, higher levels of emotional well-being were found among young perinatally infected adolescents who attended religious services, but who did not pray privately, feel God's presence or identify as religious or spiritual. Social HRQoL was significantly higher among the highest overall religious/spiritual group. Understanding adolescent profiles of religiousness/spirituality on HRQoL could inform faith-based interventions. PMID:27071797

Individuals with cerebral palsy (CP) are at increased risk for frailty and chronic disease due to factors experienced throughout the lifespan, such as excessive sedentary behaviors and malnutrition. However, little is known about noncommunicable diseases (NCDs) and multimorbidity profiles in young adults with CP. The study objective was to compare NCD and multimorbidity profiles between young adults with and without CP. A clinic-based sample of adults (18-30 years) with (n=452) and without (n=448) CP was examined at the University of Michigan Medical Center. The prevalence and predictors of 13 NCDs were evaluated, including existing diagnoses or historical record of musculoskeletal, cardiometabolic, and pulmonary morbidities. The level of motor impairment was determined by the Gross Motor Function Classification System (GMFCS) and stratified by less vs more severe motor impairment (GMFCS I-III vs IV-V). Logistic regression was used to determine the odds of NCD morbidity and multimorbidity in adults with CP compared to adults without CP, and for GMFCS IV-V compared to GMFCS I-III in those with CP, after adjusting for age, sex, body mass index, and smoking. Adults with CP had a higher prevalence of osteopenia, osteoporosis, hypertension, myocardial infarction, hyperlipidemia, asthma, and multimorbidity compared to adults without CP, and higher odds of musculoskeletal (odds ratio [OR]: 6.97) and cardiometabolic morbidity (OR: 1.98), and multimorbidity (OR: 2.67). Adults with CP with GMFCS levels IV-V had a higher prevalence of osteopenia/osteoporosis, osteoarthritis, hypertension, other cardiovascular conditions, pulmonary embolism, and multimorbidity, and higher odds of musculoskeletal (OR: 3.41), cardiometabolic (OR: 2.05), pulmonary morbidity (OR: 1.42), and multimorbidity (OR: 3.45) compared to GMFCS I-III.

MDMA (3,4-methylenedioxymethamphetamine) or 'Ecstasy' is an illicit drug frequently used by young people at parties and 'raves'. It is readily available in spite of the fact that it is illegal. 1 It is perceived by a lot of young people as being 'harmless', but there have been a few high-profile deaths associated with its use. 2 Known side effects of MDMA include hyperthermia, rhabdomyolysis, coagulopathy and cardiac arrhythmias. 3 Rarer side effects include surgical emphysema and pneumomediastinum, which have been better described with cocaine abuse. 4-6 We present a case of bilateral pneumothorax, surgical emphysema and pneumomediastinum in a young man after taking ecstasy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

We report on measurements of the luminosity function of early (young) and late-type (old) stars in the central 0.5 pc of the Milky Way nuclear star cluster as well as the density profiles of both components. The young (~ 6 Myr) and old stars (> 1 Gyr) in this region provide different physical probes of the environment around a supermassive black hole; the luminosity function of the young stars offers us a way to measure the initial mass function from star formation in an extreme environment, while the density profile of the old stars offers us a probe of the dynamical interaction of a star cluster with a massive black hole. The two stellar populations are separated through a near-infrared spectroscopic survey using the integral-field spectrograph OSIRIS on Keck II behind the laser guide star adaptive optics system. This spectroscopic survey is able to separate early-type (young) and late-type (old) stars with a completeness of 50% at K' = 15.5. We describe our method of completeness correction using a combination of star planting simulations and Bayesian inference. The completeness corrected luminosity function of the early-type stars contains significantly more young stars at faint magnitudes compared to previous surveys with similar depth. In addition, by using proper motion and radial velocity measurements along with anisotropic spherical Jeans modeling of the cluster, it is possible to measure the spatial density profile of the old stars, which has been difficult to constrain with number counts alone. The most probable model shows that the spatial density profile, n(r) propto r-γ, to be shallow with γ = 0.4 ± 0.2, which is much flatter than the dynamically relaxed case of γ = 3/2 to 7/4, but does rule out a 'hole' in the distribution of old stars. We show, for the first time, that the spatial density profile, the black hole mass, and velocity anisotropy can be fit simultaneously to obtain a black hole mass that is consistent with that derived from

This study examined profiles of non-residential father engagement (i.e., support to the adolescent, contact frequency, remarriage, relocation, and interparental conflict) with their adolescent children (N = 156) six to eight years following divorce and the prospective relation between these profiles and the psychosocial functioning of their offspring, nine years later. Parental divorce occurred during late childhood to early adolescence; indicators of non-residential father engagement were assessed during adolescence, and mental health problems and academic achievement of offspring were assessed nine years later in young adulthood. Three profiles of father engagement were identified in our sample of mainly White, non-Hispanic divorced fathers: Moderate Involvement/Low Conflict, Low Involvement/Moderate Conflict, and High Involvement/High Conflict. Profiles differentially predicted offspring outcomes nine years later when they were young adults, controlling for quality of the mother-adolescent relationship, mother’s remarriage, mother’s income, and gender, age and offspring mental health problems in adolescence. Offspring of fathers characterized as Moderate Involvement/Low Conflict had the highest academic achievement and the lowest number of externalizing problems nine years later compared to offspring whose fathers had profiles indicating either the highest or lowest levels of involvement but higher levels of conflict. Results indicate that greater paternal psychosocial support and more frequent father-adolescent contact do not outweigh the negative impact of interparental conflict on youth outcomes in the long-term. Implications of findings for policy and intervention are discussed. PMID:24484456

Studies in mature adults suggest that the plasma concentration ratio of triglyceride (TG)/HDL-cholesterol (HDL-C) provides a simple way to identify apparently healthy individuals who are insulin resistant (IR) and at increased cardiometabolic risk. This study extends these observations by examining the clinical utility of the TG/HDL-C ratio and the metabolic syndrome (MetS) in 2,244 healthy college students (17–24 years old) of Mexican Mestizo ancestry. The TG/HDL-C ratio separating the 25% with the highest value was used to identify IR and increased cardiometabolic risk. Cardiometabolic risk factors were more adverse in men and women whose TG/HDL-C ratios exceeded 3.5 and 2.5, respectively, and approximately one third were identified as being IR. The MetS identified fewer individuals as being IR, but their risk profile was accentuated. In conclusion, both a higher TG/HDL-C ratio and a diagnosis of the MetS identify young IR individuals with an increased cardiometabolic risk profile. The TG/HDL-C ratio identified a somewhat greater number of “high risk” subjects, whereas the MetS found a group whose risk profile was somewhat magnified. These findings suggest that the TG/HDL-C ratio may serve as a simple and clinically useful approach to identify apparently healthy, young individuals who are IR and at increased cardiometabolic risk.

Assessing the prevalence of relevant risk factors among young adults is a critical step in the process of preventing atherosclerotic cardiovascular diseases (ASCVD) later in life. The Israel Defense Force Periodic Health Examination Center performs a routine check-up for subjects aged 25-45 years. Medical history, physical examination notes, laboratory results and ECG tracings are recorded, computerized and processed to form the Young Adults Periodic Examinations in Israel (YAPEIS) database. Data representing 31,640 subjects (27,769 males and 3871 females) examined between the years 1991-1999 were analyzed. The prevalence of documented risk factors for ASCVD were evaluated. The results of all parameters were graded categorically as low, moderate or high and the Framingham risk score was calculated. Fifty-one percent of the study participants were found to be overweight (body mass index > or = 25 kg/m2), 8.5% had high systolic blood pressure and 14.6% had high diastolic blood pressure. The prevalence of hypercholesterolemia and hyperglycemia was found to be 44.7 and 9.7%, respectively. Thirty-two percent of the subjects smoked cigarettes, and 76.7% reported not performing any routine physical activity. Furthermore, 31.8% had a Framingham score indicating a greater than 5% risk for developing a coronary event within the next 10 years. As expected, the prevalence of these risk factors increased with age and were found to be less frequent among females. Thus we conclude that many young Israeli adults hold significant risk factors for future ASCVD. Many of these risk factors are modifiable, and risk behavior is often amenable to alteration. Awareness to the high prevalence of risk factors among young adults should spark vigorous health-promotion programs as well as screening, education, and interventional measures aimed at altering the expected outcome of future ASCVD.

The aim of the present study was to characterize the injuries of young dancers attending Centres for Advanced Training. 806 dancers, ages 10-18 years responded to surveys regarding their biological profile, dance experience and injury history, and were examined for their anthropometric profile. Of the 806 dancers, 347 reported an injury. Based on 4 age groups, the total hours of practice per week increased significantly with increasing age. Incidence of injuries per 1000 h of dance practice for dancers ages 11-12 were found to be significantly higher compared to the incidence for dancers ages 13-18 (p<0.05). Foot and ankle and other lower extremities were the most common injury location, and muscle injuries were the most common type of injury. Total months in CAT training (OR=1.044, 95% CI=1.014-1.075) and hours per week in creative style practice (OR=1.282, 95% CI=1.068-1.539) were found to be significantly associated with injuries. In conclusion, both young and mature dancers are exposed to extensive risk of injury. The intensity of training (such as number of months and number of hours of training per week) is important factor that should be taken into account in order to decrease future injuries among young dancers. © Georg Thieme Verlag KG Stuttgart · New York.

To study the influence of nasolabial angle alteration on facial profile attractiveness and investigate the perception differences in profile attractiveness among laypeople. A young Chinese female with normal hard and soft tissue cephalometric values was chosen as a research object. Profile photograph was taken in a natural head position. Photoshop software was chosen to rotate the nose tip and upper lip, thus changing the degree and direction of nasolabial angle. A total of 33 different profile pictures were achieved. Thirty-three professional orthodontists and 64 non-professionals were chosen to score these 33 pictures. When the upper lip position was fixed, the profile was considerably attractive because the angle of nasal tip was not changed or altered. When the nasal tip rotation angle was fixed, profiles with a retroclined upper lip were considered significantly attractive by the layperson and professional groups. Regardless of the direction of the nasal tip rotation, the respondents considered the profile with a retroclined upper lip highly attractive. The soft tissue profile with a retroclined upper lip looks considerably attractive in Chinese female populations. Therefore, during an orthodontic treatment, appropriate retraction of the incisor is recommended to improve soft tissue profile attractiveness.

The Full-Scale Emplacement (FE) Experiment at the Mont Terri underground research laboratory in Switzerland is a full-scale heater test in a clay-rich formation (Opalinus Clay). Based on the Swiss disposal concept it simulates the construction, emplacement, backfilling, and post-closure thermo-hydro-mechanical (THM) evolution of a spent fuel / vitrified high-level waste (SF / HLW) repository tunnel in a realistic manner. The main aim of this experiment is to investigate SF / HLW repository-induced THM coupled effects mainly in the host rock but also in the engineered barrier system (EBS), which consists of bentonite pellets and blocks. A further aim is to gather experience with full-scale tunnel construction and associated hydro-mechanical (HM) processes in the host rock. The entire experiment implementation (in a 50 m long gallery with approx. 3 m diameter) as well as the post-closure THM evolution will be monitored using a network of several hundred sensors (state-of-the-art sensors and measurement systems as well as fiber-optic sensors). The sensors are distributed in the host rock's near- and far-field, the tunnel lining, the EBS, and on the heaters. The heater emplacement and backfilling has not started yet, therefore only the host rock instrumentation is installed at the moment and is currently generating data. We will present the instrumentation concept and rationale as well as the first monitoring results of the excavation and ventilation phase. In particular, we investigated the excavation induced hydraulic response of the host rock. Therefore, the spatiotemporal evolution of porewater-pressure time series was analyzed to get a better understanding of HM coupled processes during and after the excavation phase as well as the impact of anisotropic geomechanic and hydraulic properties of the clay-rich formation on its hydraulic behavior. Excavation related investigations were completed by means of inclinometer data to characterize the non-elastic and time

Many visitors, including military troops, who enter highland regions from low altitude areas may suffer from acute mountain sickness (AMS), which negatively impacts workable man-hours and increases healthcare costs. The aim of this study was to evaluate the population level risk factors and build a multivariate model, which might be applicable to reduce the effects of AMS on Chinese young men traveling to this region. Chinese highland military medical records were used to obtain data of young men (n = 3727) who entered the Tibet plateau between the years of 2006-2009. The relationship between AMS and travel profile, demographic characteristics, and health behaviors were evaluated by logistic regression. Univariate logistic models estimated the crude odds ratio. The variables that showed significance in the univariate model were included in a multivariate model to derive adjusted odds ratios and build the final model. Data corresponding to odd and even years (2 subsets) were analyzed separately and used in a simple cross-validation. Univariate analysis indicated that travel profile, prophylactic use, ethnicity, and province of birth were all associated with AMS in both subsets. In multivariate analysis, young men who traveled from lower altitude (600-800 m vs. 1300-1500 m, adjusted odds ratio (AOR) = 1.32-1.44) to higher altitudes (4100-4300 m vs. 2900-3100 m, AOR = 3.94-4.12; 3600-3700 m vs. 2900-3100 m, AOR = 2.71-2.74) by air or rapid land transport for emergency mission deployment (emergency land deployment vs. normal land deployment, AOR = 2.08-2.11; normal air deployment vs. normal land deployment, AOR = 2.00-2.20; emergency air deployment vs. normal land deployment, AOR = 2.40-3.34) during the cold season (cold vs. warm, AOR = 1.25-1.28) are at great risk for developing AMS. Non-Tibetan male soldiers (Tibetan vs. Han, AOR = 0.03-0.08), born and raised in lower provinces (eastern vs. northwestern, AOR = 1.32-1.39), and deployed without prophylaxis

Background The gut microbiota plays an important role in human metabolism; previous studies suggest that the imbalance can cause a metabolic endotoxemia that may be linked to weight gain and insulin resistance. The purpose of this study was to investigate the relationship between the gut microbiota composition, the lipopolysaccharide levels and the metabolic profile in obese and normal-weight young subjects. Methods We studied 32 obese (BMI ≥ 30 kg/m2) and 32 normal-weight subjects (BMI = 18.5-24.9 kg/m2), aged 18-25 years. Quantification of intestinal bacteria was performed by real-time PCR. Endotoxin units were determined with the test QCL-1000, and biochemical profile was performed under a standard protocol of Spinreact. Results Obese individuals had a BMI of 34.5 (32.9-36.45) kg/m2, increased triglycerides (123 vs. 70 mg/dl), total cholesterol (168 vs. 142 mg/dl), and LDL-cholesterol (114 vs. 96.5 mg/dl). In obese subjects body temperature was higher than in normal-weight subjects. We found a greater number of Clostridum leptum and Lactobacillus (p < 0.001) and lower numbers of Prevotella and Escherichia coli (p < 0.001) in the obese group. A decrease of E. coli was associated with an increased risk of lipopolysaccharide levels ranging from 1 to 1.3 EU/ml. A positive correlation was found between serum lipopolysaccharides and BMI (r = 0.46, p = 0.008), triglyceride levels (r = 0.44, p = 0.011) as well as waist circumference (r = 0.34, p = 0.040), being more evident in young obese females. Conclusion Subclinical metabolic endotoxemia determined by serum concentration of lipopolysaccharides was related to the smallest amount of E. coli, high triglyceride levels, and central adiposity in obese young persons.

With large numbers of young people experiencing mental health difficulties but not seeking help, there is a need to develop not only innovative but also well-promoted strategies that are appealing to this population and reduce barriers to help seeking. Reach Out! (http://www.reachout.com.au) is presented as a case study, demonstrating an internet-based initiative that sucessfully incorporates technology and social branding to provide a service that promotes the mental health and wellbeing of young people in Australia aged 16 to 25. With over seven million visits since its launch in 1998 and one in three young Australians aware of the website, Reach Out! is a trusted service that young people in Australia use when going through a tough time. Online user profiling suggests that after visiting Reach Out!, 38% of young people contact a mental health professional. The implications of these results will be discussed. Reach Out! can serve as a model for the social sector to utilize technology and social branding to enhance existing community-based services and promote the mental health and wellbeing of young people.

Background: Determining somatic models and profiles in young athletes has recently become a fundamental element in selecting basketball playing positions. The aim of this study was to assess the relationship between the body build of young and adult elite male basketball players at different playing positions. Methods: Participants consisted of 35 young (age: 14.09 ± 0.30 years, n = 35) and 35 adult professional basketball players (age: 24.45 ± 5.40 years, n = 35) competing in elite leagues. The anthropometric characteristics assessed included body mass, body height, skinfolds, somatotypes, girths, and breadths. Results: The centers in both age groups were significantly taller and heavier (p < 0.001) compared to forwards and guards. The greatest difference between categories were in the guards’ personal height (from 169.36 to 186.68 = 17.32 cm). The guards from the professional team were closest in height to the forwards (difference = 7.17 cm) compared to young players where the difference between guards and forwards was 13.23 cm. Young competitors were more ectomorphic (2.12-3.75-4.17), while professional players were more mesomorphic (2.26-4.57-3.04). Significant criteria for center selection at professional level seems to be personal height and arm span ratio. Conclusions: The results indicate that the selection for basketball playing positions should include the analysis of body height and mass, shoulder breadth, humerus breadth, femur breadth and specifically for centers the difference between personal the height and arm span.

Journal of Sports Sciences, 17, 861-872; Terry, P. C., Lane, A. M., & Fogarty, G. J. (2003). Construct validity of the Profile of Mood States-Adolescents for use with adults. Psychology of Sport & Exercise, 4, 125-139.), the present study examined the validity and internal consistency reliability of the Chinese version of the Brunel Mood Scale (BRUMS-C) among 2,548 participants, comprising adolescent athletes (n = 520), adult athletes (n = 434), adolescent students (n = 673), and adult students (n = 921). Both adolescent and adult athletes completed the BRUMS-C before, during, or after regular training and both adolescent and adult students completed the BRUMS-C in a classroom setting. Confirmatory factor analyses (CFAs) provided support for the factorial validity of a 23-item six-factor model, with one item removed from the hypothesised measurement model. Internal consistency reliabilities were satisfactory for all subscales across each of the four samples. Criterion validity was supported with strong relationships between the BRUMS-C, abbreviated POMS, and Chinese Affect Scale consistent with theoretical predictions. Multi-sample CFAs showed the BRUMS-C to be invariant at the configural, metric, strong, and structural levels for all samples. Furthermore, latent mean difference analyses showed that athletes reported significantly higher levels of fatigue than students while maintaining almost the same levels of vigour, and adolescent students reported significantly higher levels of depressed mood than the other three samples.

Gene expression is dynamically regulated in a variety of mammalian physiologies. During mammalian aging, there are changes that occur in protein expression that are highly controlled by the regulatory steps in transcription, post-transcription, and post-translation. Although there are global profiles of human transcripts during the aging processes available, the mechanism(s) by which transcripts are differentially expressed between young and old cohorts remains unclear. Here, we report on N6-methyladenosine (m6A) RNA modification profiles of human peripheral blood mononuclear cells (PBMCs) from young and old cohorts. An m6A RNA profile identified a decrease in overall RNA methylation during the aging process as well as the predominant modification on proteincoding mRNAs. The m6A-modified transcripts tend to be more highly expressed than nonmodified ones. Among the many methylated mRNAs, those of DROSHA and AGO2 were heavily methylated in young PBMCs which coincided with a decreased steady-state level of AGO2 mRNA in the old PBMC cohort. Similarly, downregulation of AGO2 in proliferating human diploid fibroblasts (HDFs) also correlated with a decrease in AGO2 mRNA modifications and steady-state levels. In addition, the overexpression of RNA methyltransferases stabilized AGO2 mRNA but not DROSHA and DICER1 mRNA in HDFs. Moreover, the abundance of miRNAs also changed in the young and old PBMCs which are possibly due to a correlation with AGO2 expression as observed in AGO2-depleted HDFs. Taken together, we uncovered the role of mRNA methylation on the abundance of AGO2 mRNA resulting in the repression of miRNA expression during the process of human aging. © 2018 The Authors.

Accidental drowning accounts for 15% of all accidental deaths in Pinellas County, Florida, and this study was conducted to better understand the epidemiologic profile of the victim. The medical examiner's records of 230 drownings in Pinellas County from January 1, 1983, through December 31, 1987, were reviewed for demographic and epidemiologic data. Bodies of salt water were the most common drowning site (47%), followed by swimming pools (22%), lakes (11%), baths (7%), and canals (6%). The drowning incidence for males was more than three times that for females. Drowning was endemic among boys less than five years of age (30/100,000/year). Fifty-nine percent of young adult victims had detectable postmortem blood alcohol levels. Drowning rates were highest among children less than five years and adults more than 80 years. Epidemiologic profiles of populations at risk and contributing factors are described and public safety measures are suggested.

Unequal on top: Gender profiling and the income gap among high earner male and female professionals.

PubMed

Merluzzi, Jennifer; Dobrev, Stanislav D

2015-09-01

We develop a comprehensive, multi-level model of income inequality between high earner men and women during the early career stages. We argue that young women are routinely subjected to "gender profiling" by employers-women's potential contribution to the organization is interpreted through the lens of social stereotypes and cultural norms that attribute to them weaker labor market commitment than men. We investigate two specific mechanisms that arise from this profiling and lead to income inequality: First, women have diminished access to resources and advancement opportunities within the firm which results in lower returns to tenure for women than for men. Second, external mobility is greatly beneficial for men but much less so for women because it reinforces the image of weak commitment. Salary regressions of early career history data of young MBA alumni of a prestigious U.S. business school accord with our conjectures. Copyright © 2015 Elsevier Inc. All rights reserved.

To examine the relationship between young Australians' cyberbullying experiences, their help-seeking practices and associated mental well-being and social connectedness, with a view to informing national health and well-being agendas. An online survey was administered to young people aged 12-18 years (n = 2,338), recruited across Australia in year 2 of a larger 4-year study. Youth with no experience of cyberbullying had better well-being profiles and mental health overall. Conversely, cyberbully victims, had poorer well-being and mental health and tended not to engage with online support services, in spite of being more likely to be online after 11 pm. Parents and peers were identified as key sources of help for most young people when dealing with problems. Cyberbullying is a public health issue particularly for vulnerable youth whose mental health and well-being is impacted more than those not involved. As youth are spending increasing time in the 24/7 online environment, there is a need to develop initiatives that engage young people and encourage help-seeking online, whilst concomitantly building capacity of parents and peers to support their well-being.

Deformation mechanisms and evolution of the microstructure of gouge in the Main Fault in Opalinus Clay in the Mont Terri rock laboratory (CH)

Laurich, Ben; Urai, Janos L.; Vollmer, Christian; Nussbaum, Christophe

2018-01-01

We studied gouge from an upper-crustal, low-offset reverse fault in slightly overconsolidated claystone in the Mont Terri rock laboratory (Switzerland). The laboratory is designed to evaluate the suitability of the Opalinus Clay formation (OPA) to host a repository for radioactive waste. The gouge occurs in thin bands and lenses in the fault zone; it is darker in color and less fissile than the surrounding rock. It shows a matrix-based, P-foliated microfabric bordered and truncated by micrometer-thin shear zones consisting of aligned clay grains, as shown with broad-ion-beam scanning electron microscopy (BIB-SEM) and optical microscopy. Selected area electron diffraction based on transmission electron microscopy (TEM) shows evidence for randomly oriented nanometer-sized clay particles in the gouge matrix, surrounding larger elongated phyllosilicates with a strict P foliation. For the first time for the OPA, we report the occurrence of amorphous SiO2 grains within the gouge. Gouge has lower SEM-visible porosity and almost no calcite grains compared to the undeformed OPA. We present two hypotheses to explain the origin of gouge in the Main Fault: (i) authigenic generation consisting of fluid-mediated removal of calcite from the deforming OPA during shearing and (ii) clay smear consisting of mechanical smearing of calcite-poor (yet to be identified) source layers into the fault zone. Based on our data we prefer the first or a combination of both, but more work is needed to resolve this. Microstructures indicate a range of deformation mechanisms including solution-precipitation processes and a gouge that is weaker than the OPA because of the lower fraction of hard grains. For gouge, we infer a more rate-dependent frictional rheology than suggested from laboratory experiments on the undeformed OPA.

Circulating extracellular RNAs (exRNAs) are potential biomarkers of disease. We thus hypothesized that age-related changes in exRNAs can identify age-related processes. We profiled both large and small RNAs in human serum to investigate changes associated with normal aging. exRNA was sequenced in 13 young (30-32 years) and 10 old (80-85 years) African American women to identify all RNA transcripts present in serum. We identified age-related differences in several RNA biotypes, including mitochondrial transfer RNAs, mitochondrial ribosomal RNA, and unprocessed pseudogenes. Age-related differences in unique RNA transcripts were further validated in an expanded cohort. Pathway analysis revealed that EIF2 signaling, oxidative phosphorylation, and mitochondrial dysfunction were among the top pathways shared between young and old. Protein interaction networks revealed distinct clusters of functionally-related protein-coding genes in both age groups. These data provide timely and relevant insight into the exRNA repertoire in serum and its change with aging. Published 2018.

Petridou, Anatoli; Lazaridou, Despina; Mougios, Vassilis

2005-08-01

Although chronic exercise is generally believed to improve the lipidemic profile, it is not clear whether this is due to exercise training or to other determinants such as the usually low body fat of athletes. The aim of the present study was to compare the lipidemic profile of young lean athletes and non-athletes matched for percentage body fat. Fourteen endurance athletes and fourteen sedentary men participated in the study. Participants provided two blood samples at the beginning and end of a 7-d period, during which they recorded physical activity and food intake. Athletes had significantly higher energy expenditure and energy intake but not significantly different macronutrient composition of their diet from non-athletes. No significant differences were found in serum triacylglycerol, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol concentrations between groups. These data suggest that athletes and non-athletes with similar body fat do not differ in their lipidemic profiles.

To quantify the changes in the lens profile with accommodation in different age groups. The Pentacam HR system was used to obtain the images of the anterior eye segment from 23 young and 15 presbyopic emmetropic subjects in unaccommodated (with an accommodation stimulus of 0.0D) and accommodated (with an accommodation stimulus of 5.0D for the young group and 1.0D for the presbyopic group) states. The phakic crystalline lens shape, including curvature of crystalline lens and central lens thickness (CLT), and the measurements of anterior segment length (ASL), central anterior chamber depth (CACD) were investigated. The anterior chamber volume (ACV) was also measured. The reduction of CACD and ACV were significant in both groups after accommodation stimulus. From the profile of anterior eye segment, a significant decrease in anterior crystalline lens radii of curvature (-2.52mm) and a mean increase in CLT (0.222mm) and ASL (0.108mm) were found in the young group with an accommodation stimulus of 5.0D. However, no statistically significant changes of CLT, ASL, or crystalline lens radii of curvature were found in the presbyopic group. Our data showed that the shallowing of anterior chamber during accommodation was caused by the forward bulging of the anterior lens surface, rather than by anterior shifting of lens position in either young or presbyopic subjects.

An Analysis of natural mentoring relationship profiles and associations with mentees’ mental health: considering links via support from important others

2015-01-01

We explored associations between natural mentoring relationship profiles and young adults’ life satisfaction and symptoms of depression via participants’ perceived support from important others accounting for participants’ perceived support and mental health prior to the onset of their natural mentoring relationships. Participants included 396 young adults (57% female; mean age = 30.97, SD = .6), the majority of whom identified as Black or African American (79% Black, 18% White, 3% Biracial). Most participants had completed high school but few participants (13%) had completed degrees from 4-year institutions. We used a latent profile approach to identify natural mentoring relationship profiles and employed structural equation modeling to test our study hypotheses. Slightly over half of study participants (53%) reported the presence of a natural mentor in their lives since the age of 14. Results suggest that natural mentoring relationships characterized by high levels of relational closeness and either extended relationship duration or frequent contact may promote improvements in psychological well-being among mentees over time via greater experiences of social support from important others.

The prevalence and correlates of self-harm and suicidal behavior in 515 young offenders (mean age 17.3 years, SD = 1.7) serving community-based orders (CBOs; n = 242) or custodial sentences (n = 273) in Victoria, Australia, are described. Results from structured interviews showed that 83 (16.1%) participants reported self-harming in the previous 6 months, and this was more common among those serving custodial sentences than those serving CBOs (19.4% vs. 12.4%; OR 3.10, 95% CI: 1.74-5.55). Multiple incidents were more common in females and 24% (95% CI: 19-39) of participants who had self-harmed reported having done so with suicidal intent. Self-harm was associated with recent bullying victimization, expulsion from school, past year violent victimization, cannabis dependence, and risk-taking behavior in the preceding year. The epidemiological profile of self-harm in this population appears to be distinct from that seen in the general population. Young offenders who self-harm are a vulnerable group with high rates of psychiatric morbidity, substance misuse problems, and social risk factors. They may benefit from targeted psychological interventions designed specifically to address impulsivity, delivered both within-and during the transition from-the youth justice system. © 2014 The American Association of Suicidology.

In the context of reforms in the field of disability, this study documents the trajectories and mechanisms of support for young people with mental illness or intellectual disability or pervasive developmental disorders, during the teen-adult life transition period; andfactorsfostering or impeding this transition for their maintenance in an everyday environment, particularly in SESSAD (special education and home care service) and the SAMSAH/ SPAC (medico-social support for adults with disabilities/support services in social life). This study was conducted in the French department of Seine-et-Marne. It was supported by a mixed call for tenders, in which 77 respondents (professionals, families and users), and 26 organizations were consulted. The study shows that few young adults in SAMSAH/SPAC programmes are derived from SESSAD, and they encounter major difficulties living in an everyday environment, particularly during the transition period. Clinical or socio-economic factors related to the profiles of users or healthcare service organization facilitate or hinder the inclusion of young people in an everyday environment. Support for users was also often limited to followup over a suboptimal period, and was hampered by insufficient networking within the regional healthcare system. On the other hand, empowerment of users and their optimal inclusion in an everyday environment, as founding principles of the reform, constitute major action priorities for healthcare structures. Strengthening services for young people (16-25 years), including integration strategies, is recommended in order to establish an integrated network of services in the field of disability.

To assess adolescent and young adult determinants of visceral adipose tissue (VAT) at ages 26-28 years. Prospective study (ages 9-28 years) of cardiometabolic measures, menarche age, menses irregularities, metabolic syndrome, impaired fasting glucose-type 2 diabetes mellitus, and VAT in 400 girls (248 black, 152 white). Adolescent (age 14-19) independent variables for greater VAT at ages 26-28 included larger mean waist circumference (partial R(2) = 30.8%), earlier age at menarche (0.9%), and white race (1.8%). Young adult (ages 20-28 years) independent variables for greater VAT included larger mean waist circumference (partial R(2) = 61.7%), greater triglyceride levels (3.3%), lower high-density lipoprotein cholesterol (1.0%), and greater insulin resistance (homeostasis model assessment-estimated insulin resistance; 0.4%). Independent variables for greater VAT when both adolescent and young adult variables were used included waist (tertile rank change from adolescence to young adulthood, partial R(2) = 58.3%), greater young adult triglyceride levels (4.4%), white race (1.8%), greater young adult homeostasis model assessment-estimated insulin resistance (age 20-28, 2.4%), and earlier menarche age (0.7%). Menses irregularities were not independently associated with young adult VAT. Adolescent girls with early menarche and larger waist circumference should be targets for primary prevention of accretion of VAT. In young adulthood, VAT is associated with dysregulated cardiometabolic profiles, which is greater for those with waist circumference increases from adolescence to adulthood. Waist circumference during young adulthood, and to a lesser degree during adolescence, is an inexpensive surrogate for VAT at ages 26-28 years. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim of this study was to compare the kinematic characteristics of tennis matches between red clay and hard courts in young tennis players. Eight young tennis players performed two tennis matches on different court surfaces. The match activities were monitored using GPS units. The distance covered in different velocity ranges and the number of accelerations were analyzed. The paired t test and inference based on magnitudes were used to compare the match physical performance between groups. The total distance (24% of difference), high-intensity running distance (15 - 18 km/h) (30% of difference), the number of high-intensity activities (44% of difference), the body load (1% of difference), and accelerations >1.5 g (1.5-2 g and >2 g 7.8 and 8.1 % of difference, respectively) were significantly greater in clay court than hard court matches ( p < 0.05). Matches played on the red clay court required players to cover more total and high-intensity running distances and engage in more high-intensity activities than the matches played on the hard court. Finally, on the clay court the body load and the number of accelerations performed (>1.5 g) were possibly higher than on the hard court.

Parallel bodies of research have described the diverse and complex ways that men understand and construct their masculine identities (often termed "masculinities") and, separately, how adherence to traditional notions of masculinity places men at risk for negative sexual and health outcomes. The goal of this analysis was to bring together these two streams of inquiry. Using data from a national, online sample of 555 heterosexually active young men, we employed latent class analysis (LCA) to detect patterns of masculine identities based on men's endorsement of behavioral and attitudinal indicators of "dominant" masculinity, including sexual attitudes and behaviors. LCA identified four conceptually distinct masculine identity profiles. Two groups, termed the Normative and Normative/Male Activities groups, respectively, constituted 88 % of the sample and were characterized by low levels of adherence to attitudes, sexual scripts, and behaviors consistent with "dominant" masculinity, but differed in their levels of engagement in male-oriented activities (e.g., sports teams). Only eight percent of the sample comprised a masculinity profile consistent with "traditional" ideas about masculinity; this group was labeled Misogynistic because of high levels of sexual assault and violence toward female partners. The remaining four percent constituted a Sex-Focused group, characterized by high numbers of sexual partners, but relatively low endorsement of other indicators of traditional masculinity. Follow-up analyses showed a small number of differences across groups on sexual and substance use health indicators. Findings have implications for sexual and behavioral health interventions and suggest that very few young men embody or endorse rigidly traditional forms of masculinity.

Adolescent and Young Adult Male Mental Health: Transforming System Failures Into Proactive Models of Engagement.

Rice, Simon M; Purcell, Rosemary; McGorry, Patrick D

2018-03-01

Adolescent and young adult men do poorly on indicators of mental health evidenced by elevated rates of suicide, conduct disorder, substance use, and interpersonal violence relative to their female peers. Data on global health burden clearly demonstrate that young men have a markedly distinct health risk profile from young women, underscoring different prevention and intervention needs. Evidence indicates that boys disconnect from health-care services during adolescence, marking the beginning of a progression of health-care disengagement and associated barriers to care, including presenting to services differently, experiencing an inadequate or poorly attuned clinical response, and needing to overcome pervasive societal attitudes and self-stigma to access available services. This review synthesizes key themes related to mental ill health in adolescent boys and in young adult men. Key social determinants are discussed, including mental health literacy, self-stigma and shame, masculinity, nosology and diagnosis, and service acceptability. A call is made for focused development of policy, theory, and evaluation of targeted interventions for this population, including gender-synchronized service model reform and training of staff, including the e-health domain. Such progress is expected to yield significant social and economic benefits, including reduction to mental ill health and interpersonal violence displayed by adolescent boys and young adult men.

Behaviorally activated mRNA expression profiles produce signatures of learning and enhanced inhibition in aged rats with preserved memory.

Aging is often associated with cognitive decline, but many elderly individuals maintain a high level of function throughout life. Here we studied outbred rats, which also exhibit individual differences across a spectrum of outcomes that includes both preserved and impaired spatial memory. Previous work in this model identified the CA3 subfield of the hippocampus as a region critically affected by age and integral to differing cognitive outcomes. Earlier microarray profiling revealed distinct gene expression profiles in the CA3 region, under basal conditions, for aged rats with intact memory and those with impairment. Because prominent age-related deficits within the CA3 occur during neural encoding of new information, here we used microarray analysis to gain a broad perspective of the aged CA3 transcriptome under activated conditions. Behaviorally-induced CA3 expression profiles differentiated aged rats with intact memory from those with impaired memory. In the activated profile, we observed substantial numbers of genes (greater than 1000) exhibiting increased expression in aged unimpaired rats relative to aged impaired, including many involved in synaptic plasticity and memory mechanisms. This unimpaired aged profile also overlapped significantly with a learning induced gene profile previously acquired in young adults. Alongside the increased transcripts common to both young learning and aged rats with preserved memory, many transcripts behaviorally-activated in the current study had previously been identified as repressed in the aged unimpaired phenotype in basal expression. A further distinct feature of the activated profile of aged rats with intact memory is the increased expression of an ensemble of genes involved in inhibitory synapse function, which could control the phenotype of neural hyperexcitability found in the CA3 region of aged impaired rats. These data support the conclusion that aged subjects with preserved memory recruit adaptive mechanisms to

To address chronic disease risk holistically from a behavioral perspective, insights are needed to refine understanding of the covariance of key health behaviors. This study aims to identify distinct typologies of young adults based on 4 modifiable risk factors of chronic disease using a latent class analysis approach, and to describe patterns of class membership based on demographic characteristics, living arrangements, and weight. Overall, 441 young adults aged 18-35 attending community colleges in the Minnesota Twin Cities area completed a baseline questionnaire for the Choosing Healthy Options in College Environments and Settings study, a RCT. Behavioral items were used to create indicators for latent classes, and individuals were classified using maximum-probability assignment. Three latent classes were identified: 'active, binge-drinkers with a healthy dietary intake' (13.1%); 'non-active, moderate-smokers and non-drinkers with poor dietary intake' (38.2%); 'moderately active, non-smokers and non-drinkers with moderately healthy dietary intake' (48.7%). Classes exhibited unique demographic and weight-related profiles. This study may contribute to the literature on health behaviors among young adults and provides evidence that there are weight and age differences among subgroups. Understanding how behaviors cluster is important for identifying groups for targeted interventions in community colleges.

Young people often express a preference for seeking family planning information and services from the private sector. However, in many Marie Stopes International (MSI) social franchise networks, the proportion of young clients, and particularly those under 20 years of age, remains low. Marie Stopes Madagascar (MSM) piloted a youth voucher program that joins a supply-side intervention-youth-friendly social franchisee training and quality monitoring-with a corresponding demand-side-component, free vouchers that reduce financial barriers to family planning access for young people. Young people identified by MSM's community health educators (CHEs) received a free voucher redeemable at a BlueStar social franchisee for a package of voluntary family planning and sexually transmitted infection (STI) information and services. BlueStar social franchisees-private providers accredited by MSM-are reimbursed for the cost of providing these services. We reviewed service statistics data from the first 18 months of the youth voucher program, from July 2013 to December 2014, as well as client demographic profile data from July 2015. Findings: Between July 2013 and December 2014, 58,417 vouchers were distributed to young people by CHEs through a range of community mobilization efforts, of which 43,352 (74%) were redeemed for family planning and STI services. Most clients (78.5%) chose a long-acting reversible contraceptive (LARC), and just over half (51%) of young people benefited from STI counseling as part of their voucher service. Most (78%) services were provided in the Analamanga region (the capital and its surroundings), which was expected given the population density in this region and the high concentration of BlueStar franchisees. The client profile data snapshot from July 2015 revealed that 69% of voucher clients had never previously used a contraceptive method, and 96% of clients were aged 20 or younger, suggesting that the voucher program is successfully reaching the

To evaluate the effectiveness of an integrated infant and young child feeding counseling course for transforming the knowledge, attitudes and practices of pediatricians and nutritionists working for the municipal health system of São Paulo, Brazil. A randomized intervention study enrolling 29 professionals in the intervention group and 27 in the control group. Interviewers were trained in advance to collect data on the professionals working at health centers, before and 2 months after the intervention. Three research instruments were used, the first was to assess the profile of each professional, the second assessed their knowledge and the third was a clinical observation protocol. Analysis was performed using the Kruskal-Wallis test for independent samples and the Tukey method. The results for the knowledge questionnaire showed improvements in the intervention group (p < 0.001) for the whole questionnaire and for questions on breastfeeding (p = 0.004); HIV and infant and young child feeding (p = 0.049); complementary feeding (p = 0.012); and counseling in infant and young child feeding (p = 0.004). In terms of performance, it was observed that the intervention group had significantly improved their dietary anamnesis after the intervention (p < 0.001). This course effectively promoted an increase in knowledge and improvements in dietary anamnesis performance, but the same was not true of counseling skills.

The vast majority of young people have mobile phones. This has become a must-have item in their lives, with traditional socialization spaces displaced by virtual ones. They use their mobile phones for many hours a day, to the detriment of their psychological and social functioning, showing greater vulnerability to abusive or excessive use, and more likely to become problematic or addicted users. This paper aims to study the impact of mobile phone abuse in a sample of college students, assessing the social, personal, and communicational realms and deepening understanding of the different cyberbullying profiles, analyzing who has more personal and social problems using mobiles: victims or aggressors. Whether the number of hours of mobile phone use has an effect on these problems will also be explored. The sample (1,200 students) was selected by multistage cluster sampling among the faculties of the University of Extremadura. Data were obtained through Victimization (CYB-VIC) and Aggression (CYB-AGRES) through the mobile phone scales, and the Questionnaire of Experiences related to Mobile (CERM). The results show that mobile phone abuse generates conflicts in young people of both sexes, although girls have more communication and emotional problems than boys. In addition, age, field of knowledge, victim/aggressor profile, and hours of mobile phone use are crucial variables in the communication and emotional conflicts arising from the misuse of mobile.

After the accident at the Fukushima Daiichi Nuclear Power Plant, the thyroid ultrasound screening program for children aged 0–18 at the time of the accident was started from October 2011. The prevalence of thyroid carcinomas in that population has appeared to be very high (84 cases per 296,253). To clarify the pathogenesis, we investigated the presence of driver mutations in these tumours. 61 classic papillary thyroid carcinomas (PTCs), two follicular variant PTCs, four cribriform-morular variant PTCs and one poorly-differentiated thyroid carcinoma were analysed. We detected BRAFV600E in 43 cases (63.2%), RET/PTC1 in six (8.8%), RET/PTC3 in one (1.5%) and ETV6/NTRK3 in four (5.9%). Among classic and follicular variant PTCs, BRAFV600E was significantly associated with the smaller size. The genetic pattern was completely different from post-Chernobyl PTCs, suggesting non-radiogenic etiology of these cancers. This is the first study demonstrating the oncogene profile in the thyroid cancers discovered by large mass screening, which probably reflects genetic status of all sporadic and latent tumours in the young Japanese population. It is assumed that BRAFV600E may not confer growth advantage on paediatric PTCs, and many of these cases grow slowly, suggesting that additional factors may be important for tumour progression in paediatric PTCs.

Common reed (Phragmites communis) is widely distributed as the dominant plant species in the Songnen Plain of China. The aim of this study was to investigate different physiological adaptive mechanisms to salinity tolerance between young and old leaves. The profiles of 68 metabolites were measured and studied in reed leaves by gas chromatography-mass spectrometer. The nitrogen, carbon, and pigment contents showed stronger growth inhibition for older leaves with salinity stress. In young leaves, high K + contents not only promoted cell growth, but also prevented influx of superfluous Na + ions in cells; the Ca 2+ accumulation in old leaves implied that Ca 2+ triggered the SOS-Na + exclusion system and reduced Na + toxicity. Thus, the mechanism of enhanced tolerance differed between young and old leaves. The metabolite results indicated that the young and old leaves had different mechanisms of osmotic regulation; sugars/polyols and amino acids played important roles in developing salinity tolerance in young leaves but high contents of fatty acids were important for old leaves. These results implied dramatically enhanced sugars and amino acid synthesis but inhibited energy metabolism in young leaves. In contrast, fatty acid synthesis was enhanced in old leaves. The results extended our understanding of the differences in physiological metabolism in adaptive to the salt-alkalization of soil in Songnen grassland between young and old leaves of reeds.

The purposes of this study were to (1) measure changes in the young adult Caucasian male profile through time and (2) describe the male profile depicted in current fashion magazines. Profile photographs (n = 116) of male models collected from leading fashion magazines of the last 65 years were analyzed. They were reproduced as slides, and the images were scanned and projected onto a computer monitor. Soft tissue landmarks were digitized and the profiles were corrected for size differences. Six linear, nine angular, and three proportional parameters were measured. Anteroposterior lip position, lip curl, and vermilion area showed statistically significant correlations (r > or = 31, p < 0.01) with the progression of time. Other angular measurements and vertical facial proportions did not change significantly (r < or = 17, p > 0.05). The results showed that (1) the male profile depicted in fashion magazines has changed significantly with time and the changes were in the area of the lips; and (2) there was a trend of increasing lip protrusion, lip curl, and vermilion display. We conclude that similar to the female profile, the esthetic male profile has changed with time.

Surface-brightness profiles of dwarf galaxies in the NGC 5044 Group: Implications for the luminosity-shape and scalelength-shape relationships as distance indicators

NASA Astrophysics Data System (ADS)

Young, C. K.; Currie, M. J.

2001-04-01

In a recent paper, which presents CCD photometry for fifteen dwarf and intermediate early-type galaxies in the NGC 5044 Group, it has been claimed that ``a few relatively bright galaxies with ``convex'' profiles destroy the known relation between total magnitude and the ``shape'' parameter... thus ruling out the use of this relation as a distance indicator for individual galaxies''. In the same paper, further reasons were cited supposedly ``limiting also its use as a distance indicator for groups of galaxies''. We demonstrate that none of the three relatively bright galaxies cited as possessing ``convex'' profiles actually has a convex profile, and that one of these objects should be excluded because it is a late-type galaxy. Of the two remaining objects, one has an anomalous profile shape whilst the other is brighter than one might expect from its colour alone. However, we show that all of the other issues raised have already been accounted for by Young & Currie (\\cite{you94}, \\cite{you95} & \\cite{you98}). The main implications of the new observations are: (1) that the case of one galaxy with an anomalous profile shape, N42, highlights the need for some a priori criteria to be defined in order to establish objectively which objects are not suitable for distance determinations; and (2) on the basis of another unusual galaxy, N50, colour has now been shown to be a poorer discriminant between objects of the same profile shape and scalelength (but of different central surface brightness) than previously thought. How significant this latter problem is depends on how common N50-like objects are. This consideration reinforces the case for always using the more general scalelength-shape relationship of Young & Currie (\\cite{you95}) in preference to the luminosity-shape one of Young & Currie (\\cite{you94}). Reassuringly, through a re-analysis of the same CCD photometry, we find that NGC 5044 Group galaxies observe a tight scalelength-shape relationship. This finding

Hydrodynamic models for spherically symmetric winds driven by young stellar clusters with a generalized Schuster stellar density profile are explored. For this we use both semi-analytic models and one-dimensional numerical simulations. We determine the properties of quasi-adiabatic and radiative stationary winds and define the radius at which the flow turns from subsonic to supersonic for all stellar density distributions. Strongly radiative winds significantly diminish their terminal speed and thus their mechanical luminosity is strongly reduced.

Young women with acute myocardial infarction (AMI) have a higher risk of adverse outcomes than men. However, it is unclear how young women with AMI are different from young men across a spectrum of characteristics. We sought to compare young women and men at the time of AMI on six domains of demographic and clinical factors in order to determine whether they have distinct profiles. Using data from Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO), a prospective cohort study of women and men aged ⩽55 years hospitalized for AMI ( n = 3501) in the United States and Spain, we evaluated sex differences in demographics, healthcare access, cardiovascular risk and psychosocial factors, symptoms and pre-hospital delay, clinical presentation, and hospital management for AMI. The study sample included 2349 (67%) women and 1152 (33%) men with a mean age of 47 years. Young women with AMI had higher rates of cardiovascular risk factors and comorbidities than men, including diabetes, congestive heart failure, chronic obstructive pulmonary disease, renal failure, and morbid obesity. They also exhibited higher levels of depression and stress, poorer physical and mental health status, and lower quality of life at baseline. Women had more delays in presentation and presented with higher clinical risk scores on average than men; however, men presented with higher levels of cardiac biomarkers and more classic electrocardiogram findings. Women were less likely to undergo revascularization procedures during hospitalization, and women with ST segment elevation myocardial infarction were less likely to receive timely primary reperfusion. Young women with AMI represent a distinct, higher-risk population that is different from young men.

Recent genome-wide association studies in the Mexican population have identified several genetic loci associated with blood lipid levels in adults. However, studies focusing on the fatty acid desaturase (FADS) gene cluster have been understudied in this population, even though it seems associated with lipid profiles in other ethnicities. The aim of this study was to test associations between single nucleotide polymorphisms (SNPs) in the FADS cluster (rs174546, rs1535, rs174548, rs174550, rs174450, and rs174618) and serum lipid profiles in young Mexicans. Anthropometrics, serum lipid profiles, and FADS SNPs were measured in 998 subjects in the UP-AMIGOS cohort study. Genotype-phenotype (total cholesterol [TC], triglyceride [TG], high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], and very-low-density lipoprotein [VLDL]) associations were assessed using PLINK adjusted for sex, age, and body mass index (BMI). Among 6 FADS SNPs, we found that carriers of the C-allele of the FADS1-rs174546 showed a significant association with lower TG concentrations (β = -12.6 mg/dL, p = 0.009) and lower VLDL concentrations (β = -2.52 mg/dL, p = 0.005). We found that rs174546, rs1535, and rs174550 were in high linkage disequilibrium (r2 > 0.80). There were no significant associations between rs174550, rs174548, and rs174618 and lipid profiles. A genetic variant in the FADS1 (rs174546) gene is a major contributor of plasma TG and VLDL concentrations in healthy young Mexicans. © 2018 S. Karger AG, Basel.

Suriá Martínez, Raquel

2015-09-01

To identify distinct profiles of resilience in people with spinal cord injuries due to traffic accidents and to determine whether the profiles identified are related to differences in subjective well-being. The Resilience Scale (Wagnild and Young, 1993) and an adapted quality of life scale (GENCAT) were administered to 98 people with physical disabilities due to traffic accidents. Cluster analyses identified three different resilience profiles: a high-resilience group, a low-resilience group, and a group showing a predominance of high scores in self and life acceptance and social competence. The results also revealed statistically significant differences among profiles in most domains of subjective well-being. The results suggest the need to study resilience in greater depth and to design programs to enhance quality of life among people with disabilities due to traffic accidents. Copyright © 2014 SESPAS.

With the objective of widening the use of bamboo in the food industry, the present work aimed to produce and characterize the young bamboo culm flours from varieties Dendrocalamus asper, Bambusa tuldoides and Bambusa vulgaris as potential sources of fiber and starch. The young culms were collected, cut in three sections (bottom, middle, top), processed into flour, and they were physically, chemically and technologically analyzed. The data were obtained in triplicate and evaluated by means of average differences, using analysis of variance (ANOVA) and Scott-Knott test (p<0.05). The young bamboo culms flours presented low values for moisture content (<10g/100g), protein, lipids and ash contents (<3g/100g). Regarding the carbohydrates profile, the flours were significantly different in their sugar, starch and total fiber contents. All flour samples presented a potential for fiber extraction (>60g/100g), and the varieties B. vulgaris and D. asper, presented an additional potential for starch extraction (16 and 10g/100g, respectively). Regarding technological characteristics, all flours presented bright yellow color, lightly acidic pH (>5.0), water solubility index (WSI) lower to 2.5%, excepting D. asper, which presented a WSI superior to 7.5%. In this way, the evaluated young bamboo culms present potential application in the food industry as flours and as source of fibers; in addition, the varieties D. asper and B. vulgaris can also be used for starch extraction.

The purpose of this study was to investigate the association among anthropometric, physical performance parameters, and dynamic postural control attributes of young female volleyball athletes, and to determine if differences exist in these attributes according to playing position. Forty-three young female volleyball players participated in this study. Players were divided by position into hitters (N.=17), middle blockers (N.=8), setters (N.=10), and liberos (N.=8). Stature, body mass, vertical jump (VJ), peak power, horizontal jump (HJ), sit-and-reach (SRT), star excursion balance (SEBT), and agility (e.g. shuttle run and Illinois agility test) tests were assessed on non-consecutive days in randomized order. No difference was found between groups for SRT, peak power, VJ, and HJ (P≤0.05). Middle blockers and hitters were taller than setters (P≤0.05). Middle blockers were also taller than liberos (P=0.017). Significant differences were observed among groups for agility tests, with hitters significantly faster than setters (P=0.023) and middle blockers (P=0.037). In addition, liberos were significantly faster than setters (P=0.032) and middle blockers (P=0.046), during the Illinois agility test. No difference was observed between groups for reach distance scores in the SEBT. These results demonstrate important positional differences in agility measures of young female volleyball players. Coaches can use this information to determine the type of physical profile that is needed for specific positions and to design training programs to maximize strength, power, and neuromuscular development of young female volleyball athletes.

2015-01-01

Our aim was to compare the biopsychosocial characteristics of young women with those of older women who were enrolled in cardiac rehabilitation (CR). The baseline characteristics of women who prematurely terminated CR participation were also explored. Baseline physiological and psychosocial indices of women ≤ 55 years compared with older women eligible for CR were evaluated 1 week before enrolling in either a traditional CR or a gender-specific, motivationally enhanced CR. A greater proportion of young women (n = 65) compared with their older counterparts (n = 187) were diagnosed with acute myocardial infarction during their index hospitalization. They demonstrated lower high-density lipoprotein cholesterol, higher total cholesterol/high-density lipoprotein cholesterol ratios, and greater body weight compared with older women and were more likely to be active smokers. Young women compared with older women reported significantly worse health perceptions, quality of life, optimism, hope, social support, and stress and significantly more symptoms of depression and anxiety. Women who prematurely terminated CR participation were younger, more obese, with worse quality of life, and greater symptoms of depression and anxiety compared with women completing CR. Notable differences in physiological and psychosocial profiles of young women compared with older women enrolled in CR were evident, placing them at high risk for nonadherence to secondary prevention interventions as well as increased risk for disease progression and subsequent cardiac adverse events. Continued existence of these health differentials represents an important public health problem and warrants further research to address these age-related and sex-specific health disparities among women with coronary heart disease.

To analyse pH and flow rate (FR) of unstimulated whole saliva (UWS), detecting their possible correlations both among themselves and with body profile; in addition to identify daily, annually and gender differences. Eighty-one (47 ♀; 34 ♂) healthy young adults (mean age 22.7±4.09 years old) were enrolled. Saliva was sampled using spitting method. The data were statistically analysed using Pearson's coefficient, ANOVA or Kruskal-Wallis test, Student's t test or the Wilcoxon-Mann-Whitney test. The mean UWS/FR was 0.643 ml/min (range 0.164-1.656 ml/min; percentile 25 = 0.400 ml/min; percentile 50 = 0.643 ml/min, percentile 75 = 0.832 ml/min; median = 0.590 ml/min) and no significant differences were found in gender. The mean UWS/pH was 6.95 (range 6.06-7.91, S.D. 0.28, RSD % 4.08): pH was higher in males (7.02) than females (6.92; p = 0.009). The UWS/FR increased almost steadily during the day: from 0.593 ml/min at 9:00 to 0.669 ml/min at 17:00 (p = 0.04), the greatest increase was found between 9:00 and 11:00. Through the seasons the UWS/FR decreased from summer to spring with a difference of 0.048 ml/min (p < 0.05). The UWS/pH showed a slight increase between 9:00 and 17:00 (p < 0.05). There were little differences in UWS/pH among the seasons (max. 0.09; p < 0.05). Only a significant correlation between UWS/FR and pH was found (R = 0.20; p = 0.008). We did not find correlations between body profile vs UWS/FR or pH. UWS/FR varies more widely than UWS/pH: maintaining a proper acid/base balance is an essential factor for the homeostasis of the oral cavity and probably this would explain the reason for the lack of the variables evaluated influencing UWS/pH.

Childhood dental anxiety is very common, with 10-20 % of children and young people reporting high levels of dental anxiety. It is distressing and has a negative impact on the quality of life of young people and their parents as well as being associated with poor oral health. Affected individuals may develop a lifelong reliance on general anaesthetic or sedation for necessary dental treatment thus requiring the support of specialist dental services. Children and young people with dental anxiety therefore require additional clinical time and can be costly to treat in the long term. The reduction of dental anxiety through the use of effective psychological techniques is, therefore, of high importance. However, there is a lack of high-quality research investigating the impact of cognitive behavioural therapy (CBT) approaches when applied to young people's dental anxiety. The first part of the study will develop a profile of dentally anxious young people using a prospective questionnaire sent to a consecutive sample of 100 young people referred to the Paediatric Dentistry Department, Charles Clifford Dental Hospital, in Sheffield. The second part will involve interviewing a purposive sample of 15-20 dental team members on their perceptions of a CBT self-help resource for dental anxiety, their opinions on whether they might use such a resource with patients, and their willingness to recruit participants to a future randomised controlled trial (RCT) to evaluate the resource. The third part of the study will investigate the most appropriate outcome measures to include in a trial, the acceptability of the resource, and retention and completion rates of treatment with a sample of 60 dentally anxious young people using the CBT resource. This study will provide information on the profile of dentally anxious young people who could potentially be helped by a guided self-help CBT resource. It will gain the perceptions of dental care team members of guided self-help CBT for

Adverse Childhood Experiences and Young Adult Health Outcomes among Youth Aging Out of Foster Care.

Former youth in foster care (YFC) are at greater risk of chronic health conditions than their peers. Although research in general population samples has demonstrated a dose-response relationship between adverse childhood experiences (ACEs) and adult health outcomes, few studies have conducted similar analyses in highly stress-exposed populations such as YFC. This paper uses person-centered latent class analysis (LCA) methods to examine the relationship between different profiles of ACE exposures and divergent health trajectories amongst this high-risk population. Data are from longitudinal research that followed transition-age YFC from age 17-26 (N =732). Using three subgroups previously identified by their ACEs histories, Complex, Environmental, and Lower Adversity groups, we applied group mean statistics to test for differences between the groups for physical and sexual health outcomes in young adulthood. In contrast to prior research demonstrating that the Environmental group was at the highest risk of criminal behavior outcomes, for most of the physical and sexual health risk outcomes evaluated in this paper, the Complex Adversity group had the highest risk. This study demonstrates that there are subgroups of YFC which each have a distinct profile of risk in young adulthood, with the Complex group being at highest risk of the physical and sexual health risk outcomes evaluated. Findings strongly suggest the need for targeted strategies to promote screening for ACEs and chronic health conditions, linkage to adult healthcare, and continuity of care for adolescents and young adults in foster care to offset these trajectories.

A Latent Class Analysis of Heterosexual Young Men’s Masculinities

Masters, N. Tatiana; Beadnell, Blair; Wells, Elizabeth A.; Morrison, Diane M.; Hoppe, Marilyn J.

2015-01-01

Parallel bodies of research have described the diverse and complex ways that men understand and construct their masculine identities (often termed“masculinities”) and, separately, how adherence to traditional notions of masculinity places men at risk for negative sexual and health outcomes. The goal of this analysis was to bring together these two streams of inquiry. Using data from a national, online sample of 555 hetero-sexually active young men, we employed latent class analysis (LCA) to detect patterns of masculine identities based on men’s endorsement of behavioral and attitudinal indicators of“dominant” masculinity, including sexual attitudes and behaviors. LCA identified four conceptually distinct masculine identity profiles. Twogroups, termed the Normative and Normative/Male Activities groups, respectively, constituted 88 % of the sample and were characterized by low levels of adherence to attitudes, sexual scripts, and behaviors consistent with“dominant”masculinity, but differed in their levels of engagement in male-oriented activities (e.g., sports teams). Only eight percent of the sample comprised a masculinity profile consistent with “traditional” ideas about masculinity; this group was labeled Misogynistic because of high levels of sexual assault and violence toward female partners. The remaining four percent constituted a Sex-Focused group, characterized by high numbers of sexual partners, but relatively low endorsement of other indicators of traditional masculinity. Follow-up analyses showed a small number of differences across groups on sexual and substance use health indicators. Findings have implications for sexual and behavioral health interventions and suggest that very few young men embody or endorse rigidly traditional forms of masculinity. PMID:26496914

Total magnitudes of Virgo galaxies - III. Scale errors in the Reference Catalogue of Bright Galaxies T system and light-profile distortion by resolution-degrading and differential-distance effects

NASA Astrophysics Data System (ADS)

Young, Christopher Ke-shih

2004-11-01

We investigate the BT magnitude scales of the Second and Third Reference Catalogues of Bright Galaxies, finding both scales to be reasonably reliable for 11.5 <~Bt<~ 14.0. However, large-scale errors of 0.26 and 0.24mag per unit mag interval respectively are uncovered for early-type galaxies at the bright ends, whilst even larger ones of 0.74 and 0.36mag per unit mag interval are found for galaxies of all morphological types at the faint ends. We attribute this situation to several effects already discussed by Young et al. and Young (Paper I), including the application of relatively inflexible growth-curve models that are only in a few specific cases appropriate to the galaxies concerned. Of particular interest to this study though, we find that the apparent profile shapes of giant galaxies in the Virgo direction of cz < 15000 km s-1 tend to be less centrally concentrated the greater their distance. This demonstrates that even for relatively nearby galaxies, the distortion of the overall shapes of light profiles by resolution-degrading effects such as seeing and data smoothing, as originally predicted and modelled by Young & Currie and Young et al., is a significant effect. It is, therefore, not good practice simply to extrapolate the profiles of galaxies of identical intrinsic size and intrinsic profile shape (i.e. identical morphology) by means of the same growth-curve model, unless the galaxies are known a priori to be at the same distance and unless their photometry is of the same angular resolution. We also investigate the total-magnitude scale of the catalogue of photometric types of Prugniel & Héraudeau, finding it to be much more reliable than the BT one. However, we argue that photometric type is really a measure of apparent profile shape (i.e. intrinsic profile shape after scale reduction on account of distance followed by convolution with a seeing disc and often a smoothing function as well). Strictly, it should therefore only be applicable to

This study was conducted to assess whether choices of physical activity, smoking status, and parental education and income were correlated with the health status of young adult males which are important for preventive health policy. 491 18-29-year old males from lower socioeconomical districts in Turkey participated in this study. Information about demographic characteristics, parental education, household income, smoking status, and physical activity was obtained by means of a standardized questionnaire. BMI and metabolic parameters (serum lipid profile) were assessed. Mean total cholesterol, LDL, HDL and triglyceride levels were in the normal range. The physically active group displayed a better lipid profile. No relationship was found between parental education and serum lipids. Smoking was slightly correlated with household income (r=103, p=0.022). Young adult males who participate in relatively high levels of physical activity are at lower CHD risk than less active ones. The present study also showed that lower socioecnomic status does not always correlate with higher levels of cardiovascular risk factors. In conclusion, data supports that while family history cannot be changed, HDL levels can be modulated by lifestyle factors as in other populations and that with the determined benefits of increasing physical activity and thus, HDL levels, policy reform in schools to promote physical activity are warranted.

Cold gas and the disruptive effect of a young radio jet

Newly born and young radio sources are in a delicate phase of their life. Their jets are fighting their way through the surrounding gaseous medium, strongly experiencing this interaction while, at the same time, impacting and affecting the interstellar medium (ISM). Quantifying this interplay has far reaching implications: the rate of occurrence and the magnitude of the interaction between radio jets and ISM can have consequences for the evolution of the host galaxy. Despite the hostile conditions, cold gas - neutral atomic hydrogen and molecular - has been often found in these objects and can be also associated to fast outflows. Here we present the results from two studies of H I and molecular gas illustrating what can be learned from these phases of the gas. We first describe a statistical study of the occurrence and kinematics of H I observed in absorption with the Westerbork Synthesis Radio telescope. This allows a comparison between the properties of the gas in extended and in compact/young radio sources. The study shows that the young radio sources not only have an higher detection rate of H I, but also systematically broader and more asymmetric H I profiles, most of them blueshifted. This supports the idea that we are looking at young radio jets making their way through the surrounding ISM, which also appears to be, on average, richer in gas than in evolved radio sources. Signatures of the impact of the jet are seen in the kinematics of the gas, but the resulting outflows may be characteristic of only the initial phase of the radio source evolution. However, even among the young sources, we identify a population that remains undetected in H I even after stacking their profiles. Orientation effects can only partly explain the result. These objects either are genuinely gas-poor or have different conditions of the medium, e.g. higher spin temperature. The upcoming blind H I surveys which are about to start with large-field-of-view radio facilities (i.e. Apertif

Bolignano, Davide

2014-01-01

Young people are the future of research, especially in nephrology. The prevalence of young nephrologists within the main scientific European societies varies from the 12% to 34% and the 20% of the ERA-EDTA members are less than 40 years old in 2013. Recently, the ERA-EDTA has launched a new platform, the Young Nephrologists Platform (YNP), which the aim is to become the first modern network of young nephrologists from Europe and beyond. YNP aims at promoting the aggregation of young people through modern communication channels such as social networks, blogs and through the construction of a database collecting information on attitudes and personal experiences of each young nephrologist. A mentorship program, focused and young-oriented clinical courses on hot topics and the direct involvement of young nephrologists in working groups and scientific studies are some of the other interesting initiatives driven by YNP. The future of nephrology belongs to the young and YNP could represent a good springboard for the professional growth of young nephrologists.

After the accident at the Fukushima Daiichi Nuclear Power Plant, the thyroid ultrasound screening program for children aged 0-18 at the time of the accident was started from October 2011. The prevalence of thyroid carcinomas in that population has appeared to be very high (84 cases per 296,253). To clarify the pathogenesis, we investigated the presence of driver mutations in these tumours. 61 classic papillary thyroid carcinomas (PTCs), two follicular variant PTCs, four cribriform-morular variant PTCs and one poorly-differentiated thyroid carcinoma were analysed. We detected BRAF(V600E) in 43 cases (63.2%), RET/PTC1 in six (8.8%), RET/PTC3 in one (1.5%) and ETV6/NTRK3 in four (5.9%). Among classic and follicular variant PTCs, BRAF(V600E) was significantly associated with the smaller size. The genetic pattern was completely different from post-Chernobyl PTCs, suggesting non-radiogenic etiology of these cancers. This is the first study demonstrating the oncogene profile in the thyroid cancers discovered by large mass screening, which probably reflects genetic status of all sporadic and latent tumours in the young Japanese population. It is assumed that BRAF(V600E) may not confer growth advantage on paediatric PTCs, and many of these cases grow slowly, suggesting that additional factors may be important for tumour progression in paediatric PTCs.

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are omega-3 (n-3) fatty acids (FAs) known to influence cardiometabolic markers of health. Evidence suggests that single nucleotide polymorphisms (SNPs) in the fatty acid desaturase 1 and 2 (FADS1/2) gene cluster may influence an individual's response to n-3 FAs. This study examined the impact of a moderate daily dose of EPA and DHA fish oil supplements on cardiometabolic markers, FA levels in serum and red blood cells (RBC), and whether these endpoints were influenced by SNPs in FADS1/2. Young adults consumed fish oil supplements (1.8 g total EPA/DHA per day) for 12 weeks followed by an 8-week washout period. Serum and RBC FA profiles were analyzed every two weeks by gas chromatography. Two SNPs were genotyped: rs174537 in FADS1 and rs174576 in FADS2. Participants had significantly reduced levels of blood triglycerides (-13%) and glucose (-11%) by week 12; however, these benefits were lost during the washout period. EPA and DHA levels increased significantly in serum (+250% and +51%, respectively) and RBCs (+132% and +18%, respectively) within the first two weeks of supplementation and remained elevated throughout the 12-week period. EPA and DHA levels in RBCs only (not serum) remained significantly elevated (+37% and +24%, respectively) after the washout period. Minor allele carriers for both SNPs experienced greater increases in RBC EPA levels during supplementation; suggesting that genetic variation at this locus can influence an individual's response to fish oil supplements.

The Latino Epidemiologic Paradox describes favorable health profiles for Latinos compared to non-Latino Whites (NLW) despite poverty, low education, and low access to health care. An anomaly to this paradox is increased mortality of Latino adolescent and emerging adult males. Previous research shows motor vehicle crash fatalities bear a considerable proportion of the mortality burden attributed to this anomaly. Utilizing two U.S. data sources (CDC-WISQARS and NHTSA-FARS), graphical and linear regression methods were used to analyze crash fatality trends and changes in factors that influence crash injury fatality among young Latino males age 15-24. During 1999-2006, 59,719 motor vehicle fatalities occurred among Latino, NLW and Non-Latino Black (NLB) young males. Fatality rates were 37.7, 39.6, and 29.8 per 100,000 population/year for Latinos, NLW and NLB respectively. Over the study period, young Latino male mortality rates increased 27%. By 2006, fatality rates were 41.9, 38.3 and 27.8 per 100,000 population/year for Latinos, NLW and NLB respectively. Among driver fatalities, 43% Latino, 33% NLW and 27% NLB were restrained. Fifty-seven percent of Latino drivers had blood alcohol >or=0.01 g/dl (BAC+), as did 47% of NLW drivers and 42% of NLB drivers. Over the study period, BAC+ changed little among Latinos and NLW drivers but decreased among NLB drivers. Motor vehicle fatality rates for young Latino males are rising despite increasing restraint use and leveling driver BAC+. Without racial/ethnic specific exposure data, limitations exist in discerning the cause of diverging fatality trends and further understanding specific racial/ethnic group crash fatality disparities.

Combined oral contraceptives (COCs) may increase the risk for cardiovascular disease depending on the ethynyl estradiol (EE) dose and the androgenicity of the progestogens. Our objective was to evaluate the impact of a COC containing 20 mcg EE + 3 mg drospirenone on blood pressure (BP), renin-angiotensin-aldosterone system, insulin resistance, and androgenic profile of healthy young women. Eighty-one healthy young women aged 30 ± 1 years (case group, n = 49, received COC; control group, n = 32, used no COC) were assessed twice, before and after the 6-month study. Statistical analysis employed the paired t-tests and expressed the data in mean and standard deviation. Results were as follows: no changes in BP or in BMI; a significant increase in aldosterone, plasma renin activity, triglycerides, and total cholesterol levels, but a non-significant increase in HDL and no significant changes in LDL levels (these parameters remained within normal ranges); a significant increase in the HOMA-IR index and a significant decrease in dehydroepiandrosterone sulfate (SDHEA), androstenedione, total testosterone, and free testosterone levels; no significant variations in the control group parameters. An oral contraceptive combination of a low EE dose and an anti-androgenic progestogen does not negatively influence the risk factors for a cardiovascular disease.

Ketamine, methylenedioxymethamphetamine (MDMA/ecstasy), cocaine, gamma-hydroxybutyrate (GHB), methamphetamine, and d-lysergic acid diethylamide (LSD/acid) have been identified as "club drugs" because of their link to club culture among young adults. Yet little is known about users' demographic differences in the prevalence of club drugs. This study sought to provide a comprehensive profile of users' demographic differences in prevalence of club drug use and dependence. Using time-space sampling, a stratified sample of 400 18- to 29-year-old club-going young adults was recruited into the Club Drugs and Health Project. Though participants reported using an array of club drugs, almost all participants (90.0%) were cocaine users. Although there were several sexual orientation and gender differences in recent drug exposure, patterns of use (measured in days) were fairly similar across gender, sexual orientation, and age. Finally, a majority of individuals (58.5%) met or exceeded criteria for club drug dependence, with most (61.7%) indicating cocaine was the one drug causing them significant problems. Cocaine is a major drug in club culture. It is essential to develop culturally appropriate drug education and prevention initiatives for young adults using club drugs.

Obesity is a serious public health problem because its association with the risk to develop various chronic diseases. Atherogenic dyslipidemia that often accompany obesity is also associated to the metabolic syndrome and to cardiovascular diseases. The transition from adolescence to young adulthood appears to be a period where major changes occur in the lifestyle which contributes to the development of obesity, however, little attention has been given to this transition stage. The inclination to adopt unhealthy behaviors which occurs during early adulthood may be increased on university students because their lifestyle, which is characterized by lack of time to eat a healthy diet, which can make them susceptible to obesity. To determine the prevalence of obesity and lipid levels abnormalities and their relationship in a group of university students. Transversal study of university students aged between 18 and 24 years. Body mass index, waist circumference and blood lipid profile where evaluated. Of the 620 students surveyed about one-third have either overweight or obesity. 86% of students had at least one alteration in the evaluated parameters. Lipid profile results show a high prevalence of minor alterations in levels, particularly in cholesterol linked to low density lipoproteins levels. University young students have a high prevalence of overweight and plasma lipid levels above the norm, but most are in the low-risk categories. It is necessary to establish early preventive measures aimed at promoting in the university student good eating habits and increased physical activity. Copyright AULA MEDICA EDICIONES 2014.

To characterize the circumstances surrounding initiation of injecting drug use, data were collected from 229 young, recently initiated injection drug users enrolled through community-based recruitment in Baltimore, Maryland. Gender differences in the pattern of initiation, the number of persons present at initiation, risky injection, and sexual behaviors at initiation, as well as behaviors after initiation, were examined. Overall, men and women were similar statistically with respect to age at initiation (19.5 years) and risk behaviors at initiation. While men were initiated by men (77%), women were more often initiated by women (65%), most of whom were friends (75%) or relatives (23%). The percentage of women infected with human immunodeficiency virus (HIV) was slightly greater than that of men, 17% versus 11% (P < .2), whether initiated by a man or a woman. Persons who self-initiated had a lower HIV prevalence and fewer HIV-related risk behaviors. Analysis of variance assessed differences in the HIV risk profiles of female and male IDUs who were initiated by someone of the same sex, of the opposite sex, or who self-initiated. These results indicated that (1) young women and men had similar patterns of injection initiation; (2) most women were initiated by female friends, running counter to earlier literature claims that women were initiated to injection drug use by male sex partners; and (3) women initiated by men had a marginally greater mean score on the HIV risk profile.

There is a large spectrum of fault slow rupture processes such as stable creep and slow slip that radiate no or little seismic energy, and which relationships to normal earthquakes and fault permeability variations are enigmatic. Here we present measurements of a fault slow rupture, permeability variation and seismicity induced by fluid-injection in a fault affecting the Opalinus clay (Mt Terri URL, Switzerland) at a depth of 300 m. We observe multiple dilatant slow slip events ( 0.1-to-30 microm/s) associated with factor-of-1000 increase of permeability, and terminated by a magnitude -2.5 main seismic event associated with a swarm of very small magnitude ones. Using fully coupled numerical modeling, we calculate that the short term velocity strengthening behavior observed experimentally at laboratory scale is overcome by longer slip weakening that may be favored by slip induced dilation. Two monitoring points set across the fault allow estimating that, at the onset of the seismicity, the radius of the fault patch invaded by pressurized fluid is 9-to-11m which is in good accordance with a fault instability triggering when the dimensions of the critical slip distance are overcome. We then observe that the long term slip weakening is associated to an exponential permeability increase caused by a cumulated effective normal stress drop of about 3.4MPa which controls the successive slip activation of multiple fracture planes inducing a 0.1MPa shear stress drop in the fault zone. Therefore, our data suggest that the induced earthquake that terminated the rupture sequence may have represented enough dynamic stress release to arrest the fault permeability increase, suggesting the high sensitivity of the slow rupture processes to the structural heterogeneity of the fault zone hydromechanical properties.

2003-11-01

Using "calendar" data for single women aged 15-24 from successive Demographic and Health Surveys (DHS) conducted in Colombia and Peru during the 1990s, we document trends, year by year, in sexual activity, the use of contraceptives, and subsequent reproductive outcomes. We provide evidence of the important and hitherto largely untapped potential of DHS calendar data to draw complete sexual and reproductive profiles when data from various surveys are integrated. Over the period 1985-1999, young single women in both Colombia and Peru became sexually active at younger ages. The use of contraceptives, especially the use of condoms, increased but did not fully offset the rise in sexual activity, and thus the incidence of premarital conceptions rose among young single women. In both countries, sharp declines occurred in the proportion of premaritally conceived births that were reported as being wanted.

Growing evidence suggests that early symptoms of inattentiveness may affect the language development and academic success of young children. In the present study, we examined the extent to which profiles of inattentiveness and language could be discerned within a heterogeneous group of preschoolers attending early childhood special education programs (n = 461). Based on parent-reported observations of children's symptoms of inattentiveness and direct assessments of children's language skills (grammar, vocabulary, and narrative ability), three distinct profiles were identified. The three groups, representing levels of severity (at risk, almost average, above average), differed not only by their end of year performance, but also with respect to which their abilities changed over the course of the academic year. Children in the poorest performing profile had poorer mean scores in the spring of their preschool year on all measures, but exhibited patterns of gain that exceeded or equaled their peers in higher-performing groups, in the domains of vocabulary and grammar. Examination of subsequent kindergarten reading skills suggested that profile differences remained consistent. Findings underscore the associations between early symptoms of inattentiveness and language difficulties, and further indicate that these relations extend to the acquisition of early reading skills. Future research is needed to corroborate these findings with more robust measures of attention, and to understand the long-term associations between inattentiveness, language and literacy, and potential effects on these associations from early intervention.

Dental esthetics affects how people are perceived by society and how they perceive themselves, and this may also affect their oral health-related quality of life (OHRQoL). The aim of this study was to compare the impacts of self-perceived and normatively assessed dental esthetics on the OHRQoL of a young adult population. This was a cross-sectional descriptive study involving 375 undergraduate university students, aged 18 to 30 years old. Data collection was carried out through oral examinations and self-administered questionnaires. Dental esthetics of the students was assessed using the esthetic component of the Index of Orthodontic Treatment Need. Two OHRQoL instruments were used: the shortened version of the Oral Health Impact Profile and the Psychosocial Impact of Dental Aesthetics Questionnaire. Statistically significant relationships (P <0.05) were recorded between both self-perceived and normatively assessed dental esthetics of the students, respectively, and 3 of the 4 Psychosocial Impact of Dental Aesthetics Questionnaire subscales: dental self-confidence (Kruskall-Wallis, P = 0.000; P = 0.000), psychological impact (P = 0.003, P = 0.047), and esthetic concern (P = 0.006, P = 0.003). The only exception was the social impact subscale, in which a significant relationship was recorded only with self-perceived dental esthetics (P = 0.040). For the shortened version of the Oral Health Impact Profile scale, marked differences were also observed between the impacts recorded for both self-assessments and normative assessments, respectively, particularly for the psychological disability domain (Fisher exact test, P = 0.021, P = 0.000; P = 0.064, P = 0.096). Differences exist between the impacts of self-perceived and normatively assessed dental esthetics on the OHRQoL of young adults, particularly in the psychosocial domains. These differences should be considered in orthodontic treatment planning for young adult populations. Copyright �

J Strength Cond Res 30(8): 2194-2201, 2016-Elevated lean (skeletal muscle) mass is associated with increased muscle strength and anaerobic exercise performance, whereas low levels of lean mass are associated with insulin resistance and sarcopenia. Therefore, studies aimed at obtaining an improved understanding of mechanisms related to the quantity of lean mass are of interest. Percent lean mass (total lean mass/body weight × 100) in 77 young subjects (18-35 years) was measured with dual-energy x-ray absorptiometry. Twenty analytes and 296 metabolites were evaluated with the use of the standard chemistry screen and mass spectrometry-based metabolomic profiling, respectively. Sex-adjusted multivariable linear regression was used to determine serum analytes and metabolites significantly (p ≤ 0.05 and q ≤ 0.30) associated with the percent lean mass. Two enzymes (alkaline phosphatase and serum glutamate oxaloacetate aminotransferase) and 29 metabolites were found to be significantly associated with the percent lean mass, including metabolites related to microbial metabolism, uremia, inflammation, oxidative stress, branched-chain amino acid metabolism, insulin sensitivity, glycerolipid metabolism, and xenobiotics. Use of sex-adjusted stepwise regression to obtain a final covariate predictor model identified the combination of 5 analytes and metabolites as overall predictors of the percent lean mass (model R = 82.5%). Collectively, these data suggest that a complex interplay of various metabolic processes underlies the maintenance of lean mass in young healthy adults.

Nonalcoholic fatty liver disease (NAFLD) has been considered a novel component of the metabolic syndrome (MetS), with the oxidative stress participating in its progression. This study aimed to evaluate the metabolic profile in young and old mice with MetS, and the effects of apocynin and tempol on glycemic and lipid parameters. Young and old C57BL/6 mice with high fat diet- (HFD-) induced MetS received apocynin and tempol 50 mg·kg−1/day in their drinking water for 10 weeks. After HFD, the young group showed elevated fasting glucose, worsened lipid profile in plasma, steatosis, and hepatic lipid peroxidation. Nevertheless, the old group presented significant increase in fasting insulin levels, insulin resistance, plasma and hepatic lipid peroxidation, and pronounced steatosis. The hepatic superoxide dismutase and catalase activity did not differ between the groups. Tempol and apocynin seemed to prevent hepatic lipid deposition in both groups. Furthermore, apocynin improved glucose tolerance and insulin sensitivity in old mice. In summary, old mice are more susceptible to HFD-induced metabolic changes than their young counterparts. Also, the antioxidant therapy improved insulin sensitivity and glucose tolerance, and in addition, apocynin seemed to prevent the HFD-induced hepatic fat deposition, suggesting an important role of oxidative stress in the induction of NAFLD.

Ontogeny of the daily profile of plasma melatonin in European starlings raised under long or short photoperiods.

Photoperiodic manipulation of young European starlings suggests that their reproductive physiology is incapable of responding to a short photoperiod until they are fully grown. This study aimed to determine whether the lack of response to a short photoperiod is reflected in the daily profile of plasma melatonin concentrations. Five-day-old starlings taken from nest boxes showed a significant (p < 0.0001) rhythm in plasma melatonin concentrations, with high values during night. In nestlings hand-reared from 5 days of age on a long photoperiod (LD 16:8), equivalent to natural photoperiod at the time, the amplitude of the daily rhythm in melatonin increased significantly (p < 0.01) with age until birds were fully grown (20 days old). In nestlings reared on a short photoperiod (LD 8:16), the daily melatonin profile remained almost identical to that of long photoperiod birds until they were fully grown. However, after 20 days old, the duration of elevated nighttime melatonin began to extend to encompass the entire period of darkness. In contrast, fully grown starlings transferred from a long to a short photoperiod had partially adapted to the short photoperiod after 5 days; by 10 days, the daily melatonin profile was identical to that of birds held chronically on a short photoperiod. Thus, consistent with responses of reproductive physiology, the pineal of young birds appears to be incapable of perceiving, or adapting to, a short photoperiod.

Background Non-volitional sex (NVS) in young people continues to be a major public health problem with long-term negative health outcomes. For the first time, the prevalence of different types of NVS and associated factors are compared between young people with same-sex sexual activities and those who have not. Methods We obtained data from 10,401 young women and men (aged 12 to 25 years) who participated in a population study on sexual health, the Netherlands. We calculated and compared the prevalence of six types of NVS between women who had sex with men (yWSM) or women (yWSW), and men who had sex with women (yMSW) or men (yMSM). In sexually experienced participants (n = 5986) logistic regression analyses were applied to assess associations with NVS by assault or penetration. Analyses were weighted to represent the Dutch population. Results The prevalence of NVS ranged from 1% to 61%, depending on type. Prevalence was higher for young women (any: 40.6%) than men (any: 20.4%), and highest for yMSM and yWSW. Prevalence of NVS by assault or penetration was related to a range of socio-demographic, behavioral and social factors, which were largely similar regardless of sex or same-sex-experiences. The NVS perpetrators were in over 70% of cases known to the victim; 1 in 4 cases of NVS by penetration were accompanied by violence. Conclusion A substantial proportion of young people in the Netherlands have experienced NVS. Medical professionals, educators and caregivers should integrate services to continue to address NVS by targeting young people’s multifaceted risk profiles and evidenced based interventions for doing so are needed.

To contrast the psychosocial profile of adolescents with risk factors for homelessness, identified using Chamberlain and MacKenzie's self-report scale, compared to the profiles of homeless adolescents. Multinomial logistic regression analyses were conducted contrasting profiles for (a) 137 homeless adolescents, (b) 766 secondary students reporting risk factors for homelessness, and (c) 4,844 students not reporting risks for homelessness. Fourteen percent of a representative population of at-school adolescents, from Victoria, Australia, showed elevated risk of homelessness. These adolescents showed depressive symptoms at least equivalent to homeless adolescents (RR 6.0, 95% CI: 4.9, 7.3, and RR 3.5, 95% CI: 2.1, 5.8, respectively). In multivariate analyses, homeless and at risk adolescents reported equivalent levels of family conflict, early problem behaviour and low opportunities and rewards for family involvement. Compared to adolescents not at risk, at risk adolescents were more likely to be female and to show poorer social skills/assertiveness and depressive symptoms. Compared to at risk adolescents, homeless adolescents showed additional family, school, peer and individual risks, but lower depressive symptomatology. The findings highlight the potential we have to quickly and simply detect adolescents showing significant risk of homelessness. This sizable minority of adolescents report risks often equivalent to homeless adolescents. It is hoped that stakeholders working with young people will utilise this screening potential to identify and intervene effectively with this significant subpopulation of youth, and their families, while they are still at home and school.

2013-06-01

Vocational interests play a central role in the vocational decision-making process and are decisive for the later job satisfaction and vocational success. Based on Ackerman's (1996) notion of trait complexes, specific interest profiles of gifted high-school graduates can be expected. Vocational interests of gifted and highly achieving adolescents were compared to those of their less intelligent/achieving peers according to Holland's (1997) RIASEC model. Further, the impact of intelligence and achievement on interests were analysed while statistically controlling for potentially influencing variables. Changes in interests over time were investigated. N= 4,694 German students (age: M= 19.5, SD= .80; 54.6% females) participated in the study (TOSCA; Köller, Watermann, Trautwein, & Lüdtke, 2004). Interests were assessed in participants' final year at school and again 2 years later (N= 2,318). Gifted participants reported stronger investigative and realistic interests, but lower social interests than less intelligent participants. Highly achieving participants reported higher investigative and (in wave 2) higher artistic interests. Considerable gender differences were found: gifted girls had a flat interest profile, while gifted boys had pronounced realistic and investigative and low social interests. Multilevel multiple regression analyses predicting interests by intelligence and school achievement revealed stable interest profiles. Beyond a strong gender effect, intelligence and school achievement each contributed substantially to the prediction of vocational interests. At the time around graduation from high school, gifted young adults show stable interest profiles, which strongly differ between gender and intelligence groups. These differences are relevant for programmes for the gifted and for vocational counselling. ©2012 The British Psychological Society.

The aim of this study was to develop a novel chronic kidney disease (CKD) risk prediction tool for young potential living kidney donors. Living kidney donor selection practices have evolved from examining individual risk factors to a risk calculator incorporating multiple characteristics. Owing to limited long-term data and lack of genetic information, current risk tools lack precision among young potential living kidney donors, particularly African Americans (AAs). We identified a cohort of young adults (18-30 years) with no absolute contraindication to kidney donation from the longitudinal cohort study Coronary Artery Risk Development in Young Adults. Risk associations for CKD (estimated glomerular filtration rate <60 mL/min/1.73 m) were identified and assigned weighted points to calculate risk scores. A total of 3438 healthy adults were identified [mean age 24.8 years; 48.3% AA; median follow-up 24.9 years (interquartile range: 24.5-25.2)]. For 18-year olds, 25-year projected CKD risk varied by ethnicity and sex even without baseline clinical and genetic abnormalities; risk was 0.30% for European American (EA) women, 0.52% for EA men, 0.52% for AA women, 0.90% for AA men. Among 18-year-old AAs with apolipoprotein L1 gene (APOL1) renal-risk variants without baseline abnormalities, 25-year risk significantly increased: 1.46% for women and 2.53% for men; among those with 2 APOL1 renal-risk variants and baseline abnormalities, 25-year risk was higher: 2.53% to 6.23% for women and 4.35% to 10.58% for men. Young AAs were at highest risk for CKD, and APOL1 renal-risk variants drove some of this risk. Understanding the genetic profile of young AA potential living kidney donors in the context of baseline health characteristics may help to inform candidate selection and counseling.

Background Various Serosurveys and studies provide ample evidence of differing perspectives regarding epidemiology of HAV and HEV in India. This study was conducted to assess the seroprevalence of HAV and HEV and its associated factors with an aim to provide inputs to planners regarding requirement of HAV vaccine. Methods A multi-centric cross sectional survey amongst 4175 healthy trainees (young adults) was carried out in training centres, selected by multistage random sampling, giving equal representation to all regions of India. Sample size was calculated by taking prevalence of HAV seropositivity amongst adults as 60% and alpha 0.05. Results Seroprevalence for HAV and HEV was 92.68% (95% CI 91.82, 93.47) and 17.05% (15.90, 18.26), respectively. Logistic regression showed that hand washing without soap, regular close contact with domestic animals, consumption of unpasteurized milk and regular consumption of food outside home were risk factors for HAV (p < 0.05). For HEV, irregular hand washing, consumption of unpasteurized milk and irregular consumption of freshly prepared food were risk factors (p < 0.05). Conclusion High level of immunity against HAV among the healthy young adults clearly demonstrates that vaccination against HAV is not required at present in our country. The large proportion being susceptible to HEV points towards the requirement of preventive strategies in the form of safe drinking water supply, hygiene, sanitation, increasing awareness and behaviour change with respect to personal hygiene especially hand and food hygiene.

Styrene-butadiene rubber is a copolymer widely used in making car tires and has excellent abrasion resistance. The Young's modulus and tribology of pure styrene butadiene rubber (SBR) polymer and carbon nanotube reinforced polymer composites have been investigated using molecular dynamics simulations. The mechanism of enhanced tribology properties using carbon nanotube has been studied and discussed. The obtained Young's modulus shows the enhancement in mechanical properties of SBR polymer when carbon nanotubes are used as reinforcement. The concentration, temperature and velocity profiles, radial distribution function, frictional stresses, and cohesive energy density are calculated and analyzed in detail. The Young's modulus of SBR matrix increases about 29.16% in the presence of the 5% CNT. The atom movement velocity and average cohesive energy density in the friction area of pure SBR matrix was found to be more than that of the CNT/SBR composite. Graphical abstract Initial and final conditions of (a) pure SBR matrix and (b) CNT/SBR matrix subjected toshear loading and frictional stresses of top Fe layers of both pure SBR and CNT/SBR composite.

Differential sensitization of parenting on early adolescent cortisol: Moderation by profiles of maternal stress.

Martin, Christina Gamache; Kim, Hyoun K; Fisher, Philip A

2016-05-01

The hypothalamic-pituitary-adrenal (HPA) axis is a critical component of the body's stress-response neurobiological system, and its development and functioning are shaped by the social environment. Much of our understanding of the effects of the caregiving environment on the HPA axis is based on (a) parenting in young children and (b) individual maternal stressors, such as depression. Yet, less is known about how parenting behaviors and maternal stressors interact to influence child cortisol regulation, particularly in older children. With an ethnically diverse sample of 199 mothers and their early adolescent children (M=11.00years; 54% female), a profile analytic approach was used to investigate how multiple phenotypes of maternal stress co-occur and moderate the relation between parenting behaviors and youths' diurnal cortisol rhythms. Latent profile analysis yielded 4 profiles: current parenting stress, concurrent parenting and childhood stress, childhood stress, and low stress. For mothers with the concurrent parenting and childhood stress profile, inconsistent discipline, poor parental supervision, and harsh caregiving behaviors each were related to flattened diurnal cortisol rhythms in their adolescents. For mothers with the current parenting stress and childhood stress profiles, their use of inconsistent discipline was associated with flattened diurnal cortisol rhythms in their adolescents. For mothers with the low stress profile, none of the parenting behaviors was related to their adolescents' cortisol regulation. Findings suggest that based on mothers' stress profile, parenting behaviors are differentially related to youths' diurnal cortisol rhythms. Implications for parenting interventions are discussed.

This study was designed to compare the effects of two different relaxation techniques, namely progressive muscle relaxation (PMR) and autogenic relaxation (AGR) on moods of young soccer players. sixteen adolescent athletes (mean age: 14.1 ± 1.3) received either PMR or AGR training. Using Profile of Mood States- Adolescents, their mood states were measured one week before relaxation training, before the first relaxation session, and after the twelfth relaxation session. Mixed ANOVA revealed no significant interaction effects and no significant main effects in any of the subscales. However, significant main effects for testing sessions were found for confusion, depression, fatigue, and tension subscales. Post hoc tests revealed post-intervention reductions in the confusion, depression, fatigue, and tension subscale scores. These two relaxation techniques induce equivalent mood responses and may be used to regulate young soccer players' mood states.

To investigate injury risk behaviours among young Asian New Zealanders. Secondary analysis of data from Youth2000, a nationwide cross-sectional youth health survey conducted in 2001 in a random sample of New Zealand (NZ) secondary schools using a multimedia, computer-assisted, self-administered interview. Of the 9,567 survey participants (aged 12 to 18 years), this study was restricted to students who identified with an 'Asian' ethnic category (n=922). Many young Asian New Zealanders report engaging in injury risk behaviours, including: not using helmets when cycling; dangerous drink and drug driving; and being intentionally physically harmed by others. NZ-born Asian students are more likely than overseas-born Asian students to report most of these risky behaviours. Chinese and Indian students are less likely to engage in most of these behaviours than their NZ European peers. While young Asian New Zealanders are a relatively healthy population, many engage in well-recognised injury risk behaviours. The lower levels of these risky behaviours in Indian and Chinese students compared with NZ European students, and the positive dose-response effect seen in relation to duration of residence in NZ, are likely to be due to the effect of acculturation. Injury prevention strategies for young people in NZ need to specifically consider the diversity, context and specific risk profiles of young Asian New Zealanders. Health promotion efforts for this group should target the use of safety equipment and risky driving behaviours and consider traditional cultural practices that may be protective.

Vidarbha region in Maharashtra, India is witnessing a continuous decrease in orange crop due to the propagation of `Phytopthora root rot', a water mold disease. Under favorable conditions, the disease causing bacteria can attack the plant root system and propagates to the surface (where first visual impression is made), making difficult to regain the plant health. This research aims at co-relating eco-hydrological fluxes with disease sensing parameters of orange trees. Two experimental plots around a healthy-young and declined-young orange trees were selected for our analysis. A 3-dimentional electrical resistivity tomography (ERT) (Figure) was carried at each plot to quantify the soil moisture distribution at a vadose zone. Pedo-electric relations were obtained considering modified Archie's law parameters. ERT derived moisture data was validated with time domain reflectometry (TDR) point observations. Soil moisture profiles derived from ERT were observed to be differ marginally between the two plots. Disease quantification was done by estimating the density of Phytopthora spp. inoculum in soils sampled along the root zone. Identification of Phytopthora spp. was done in the laboratory using taxonomic and morphologic criteria of the colonies. Spatio-temporal profiles of soil moisture and inoculum density were then co-related to comment on the eco-hydrological fluxes contributing to the health propagation of root rot in orange tree for implementing effective water management practices.

This study examined the association of education level with objectively measured physical activity and sedentary time in young adults. Data from the Finnish ESTER study (2009–2011) (n = 538) was used to examine the association between educational attainment and different subcomponents of physical activity and sedentary time measured using hip-worn accelerometers (ActiGraph GT1M) for seven consecutive days. Overall physical activity, moderate-to-vigorous physical activity (MVPA), light-intensity physical activity and sedentary time were calculated separately for weekdays and weekend days. A latent profile analysis was conducted to identify the different profiles of sedentary time and the subcomponents of physical activity. The educational differences in accelerometer-measured physical activity and sedentary time varied according to the subcomponents of physical activity, and between weekdays and weekend days. A high education level was associated with high MVPA during weekdays and weekend days in both sexes, high sedentary time during weekdays in both sexes, and a low amount of light-intensity physical activity during weekdays in males and during weekdays and weekend days in females. The results indicate different challenges related to unhealthy behaviours in young adults with low and high education: low education is associated with a lack of MVPA, whereas high education is associated with a lack of light-intensity physical activity and high sedentary time especially during weekdays.

The aim of the study was to analyse the effect of Val 16Ala polymorphism in SOD2 gene on oxidative stress parameters and lipid profile of the blood during a three-month wrestling training. The study included 53 Polish young wrestlers. Blood samples were collected at the beginning of the programme and following three months of the training. The list of analysed parameters included erythrocyte and serum activities of superoxide dismutase (SOD), whole blood glutathione peroxidase (GPx) activity, total glutathione (tGSH) level, concentration of lipid hydroperoxides (LHs), total antioxidant capacity (TAC) and creatine kinase (CK) activity in the serum, as well as lipid profile parameters: triglycerides (TG), total cholesterol (TC), high-density (HDL-C), and low-density lipoprotein cholesterol (LDL-C). Three-month training resulted in a decrease in CK activity, an increase in serum SOD activity, as well as in unfavourable changes in serum lipid profile: an increase in TC, LDL-C, and TG, and a decrease in HDL-C. Aside from CK activity, all these changes seemed to be associated with presence of Val allele. Prior to the training programme, subjects with Ala/Ala genotype presented with lower levels of LHs, lower whole blood GPx activity, and lower serum concentrations of TC than the individuals with Ala/Val genotype. Both prior to and after three-month training, higher levels of tGSH were observed in Val/Val genotype as compared to Ala/Val genotype carriers. Moreover, multiple regression analysis demonstrated that SOD2 genotype was a significant predictor of pre-training whole blood GPx activity and erythrocyte SOD activity (Val/Val > Ala/Val > Ala/Ala). Altogether, these findings suggest that Val 16Ala polymorphism in SOD2 gene contributes to individual variability in oxidative stress status and lipid profile of the blood in young wrestlers, and may modulate biochemical response to training.

Few studies have explored the hormonal triggers for masturbation in infants and young children. Thus, we aimed to study the sex hormones and clinical profiles of masturbating infants and young children. This case-control study involved infants and young children who masturbate and were referred to three pediatric neurology clinics between September 2004 and 2006 (n=13), and a similar control group. All children underwent basic laboratory investigations prior to referral. Other tests included electroencephalography (n=8) and brain neuroimaging (n=9). We measured dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, free testosterone, estradiol, dehydroepiandrosterone, sex hormone-binding globulin (SHBG), and androstenedione in all participants. The median age at the first incident was 19.5 months (range, 4-36 months); the median masturbation frequency, 4 times/day; and the median duration of each event, 3.9 min. The subjects masturbated in both prone (n=10) and supine positions (n=3); two subjects used the knee-chest position. All subjects showed facial flushing; 6, friction between the thighs; 5, sweating; 9, sleeping after the event; and 12, disturbance on interruption. EEG was abnormal in one of eight subjects tested, and neuroimages were normal in all of nine subjects examined. The case and control groups had comparable levels of all sex hormones, except estradiol, which showed significantly lower levels in the case group (P=.02). Masturbation in children seems to be associated with reduced estradiol levels, but not with other sex hormones. Further studies are needed to confirm our findings.

We present the case of an 18-year-old man, previously healthy, who presented with acute quadriplegia and respiratory failure. Physical examination was compatible with a high cervical anterior spinal cord lesion. We plan to evaluate the cause of such a neurological presentation in a healthy young man. American University Medical Center, Beirut, Lebanon. The patient underwent routine blood hematological and chemistry work-up, hypercoagulable profile studies, genetic profile for thrombophelias, radiographic studies of the brain and cervical cord, cerebrospinal analysis and extensive electrophyisological studies. Magnetic resonance imaging and magnetic resonance angiogram of the brain, carotid and intracranial vessels were normal. Cerebral angiography was normal. Magnetic resonance imaging of the cervical cord revealed lesion of the anterior segment of the cervical cord between C2 and C5 levels. Hypercoagulable profile studies were normal. Electrophysiological studies confirmed an isolated lesion of the descending cortico-spinal tracts. DNA analysis revealed the presence of a G20210A mutation-causing hyperprothrombinemia. We conclude that a G20210A mutation causing-hyperprothrombinemia can cause anterior spinal artery thrombosis and anterior spinal cord infarction with the resultant neurological deficits in otherwise healthy patients.

Young offenders are at increased risk of preventable death after release from custody, but risk factors for death in this population are poorly understood. Despite their poor health profiles, no studies have examined mortality outcomes in young people who have served community-based orders. The aims of this study were to describe the causes and identify risk factors for death in a cohort of young offenders in Victoria, Australia. We interviewed young people serving a custodial (n = 273) or community-based order (n = 242) in Victoria, Australia in 2002-2003. Measures included demographics and family history, offence history, experience of victimisation, mental illness, self-harm and substance use. Deaths up to 31 December 2011 were identified through a probabilistic linkage with the National Death Index. The all-cause crude mortality rate was 4.2 (95% confidence interval 2.7-6.8) per 1000 person years and was not significantly different for those who had served custodial and community-based orders. Most deaths were due to drug overdose, traffic accidents or suicide. Adjusting for age, sex and order type, risk factors for death from the baseline interview included weekly use of opioids, sleeping pills or painkillers, polydrug use and injecting drug use. Young people who have served community-based and custodial orders are at an increased risk of preventable death. Those engaging in risky substance use, particularly injecting drug use and use of multiple central nervous system depressants, are at greatest risk. There is an urgent need to develop and rigorously evaluate preventive interventions. © 2014 Australasian Professional Society on Alcohol and other Drugs.

Assessing young unmarried men's access to reproductive health information and services in rural India

PubMed Central

2011-01-01

Background We investigated the accessibility of reproductive health information and contraceptives in a relatively less developed area of rural central India and assessed the risks facing young unmarried men. Methods This cross-sectional study used both qualitative and quantitative methods. Participants included 38 unmarried rural men in four focus-group discussions and a representative sample of 316 similarly profiled men, aged 17-22 years, in a survey. Information was collected on the men's socioeconomic characteristics; awareness, knowledge, and perceptions of family planning; attitudes toward future contraceptive use; intra-family communication; knowledge about STIs/HIV/AIDS; and access and use of condoms. Content analysis for qualitative information and descriptive analysis for survey data were used to draw conclusions. Results Young unmarried rural Indian men's sexual and reproductive health (SRH) knowledge is limited, although the majority is familiar with condoms (99%). The young men identified electronic mass media (67%) as the prime source of reproductive health information, yet they lacked detailed knowledge of various contraceptives and felt ignored by health providers, who, they felt, would be capable of providing SRH information through interpersonal communication. Young men are more concerned about avoiding infections and securing sexual pleasure and less concerned about avoiding potential pregnancies. For example, 68% of the young men were aware of condoms and their HIV/AIDS preventive role, but only about two-fifths mentioned condom use to prevent unwanted pregnancies. Although most young men (96%) knew where to access a condom, they felt uncomfortable or embarrassed doing so in their own villages or close by because of socio-cultural norms that prevented them from using contraceptives. Very few respondents (4%) disclosed using condoms themselves, but 59% said they knew someone from their peer group who had used them. Conclusions Young unmarried

Suicide in young men.

Pitman, Alexandra; Krysinska, Karolina; Osborn, David; King, Michael

2012-06-23

Suicide is second to only accidental death as the leading cause of mortality in young men across the world. Although suicide rates for young men have fallen in some high-income and middle-income countries since the 1990s, wider mortality measures indicate that rates remain high in specific regions, ethnic groups, and socioeconomic groups within those nations where rates have fallen, and that young men account for a substantial proportion of the economic cost of suicide. High-lethality methods of suicide are preferred by young men: hanging and firearms in high-income countries, pesticide poisoning in the Indian subcontinent, and charcoal-burning in east Asia. Risk factors for young men include psychiatric illness, substance misuse, lower socioeconomic status, rural residence, and single marital status. Population-level factors include unemployment, social deprivation, and media reporting of suicide. Few interventions to reduce suicides in young men have been assessed. Efforts to change help-seeking behaviour and to restrict access to frequently used methods hold the most promise. Copyright © 2012 Elsevier Ltd. All rights reserved.

Risks to young volunteers in international social projects.

2012-03-01

The number of young volunteers in international social projects has increased significantly with governmental and non-governmental project support. This paper investigates the hypothesis that the preventative medical advice currently given prior to departure is inadequate because the risk profile of young persons (<30 years) differs from that of the general population. A retrospective cross-sectional study was performed with participants of international social projects. A specific questionnaire was developed; inclusion criteria were age between 18 and 30 years at departure and a duration with the project of at least 6 months. One hundred and fifty-three data sets could be evaluated. Fifty-three percent were females; the destinations were as follows: 65.4% to Asia, 14.4% to Africa, and 10.5% to Latin America. The mean age was 20 years. Ninety percent of the participants received some kind of advice in travel medicine prior to departure. The vaccination rate was quite good, but pertussis (13.7%), yellow fever (80%), typhoid fever (54%), and rabies (49.7%) should be improved when travelling to high-risk regions. Food is a very important potential source of problems as 66% receive catering by the project, 56.2% from street stalls, and 44% were regularly invited to dine with locals. In Africa, only two-thirds of the participants of projects had regular access to safe water and the sanitary facilities were also poor; 51.7% of respondents reported new sexual contacts (one to more than six new partners). In most cases, condoms were used, but there were two unintended pregnancies. We conclude that young people need to be targeted with specialized advice for health and safety while abroad. This should highlight age-specific risks compared to advice for a more general population. Vaccination status should be improved for some regions and diseases.

Background. Thyroid carcinoma, which is rare in pediatric patients (age 0–18 years) but more common in adolescent and young adult (AYA) patients (age 15–39 years), carries the potential for morbidity and mortality. Methods. Hybrid‐capture‐based comprehensive genomic profiling (CGP) was performed prospectively on 512 consecutively submitted thyroid carcinomas, including 58 from pediatric and AYA (PAYA) patients, to identify genomic alterations (GAs), including base substitutions, insertions/deletions, copy number alterations, and rearrangements. This PAYA data series includes 41 patients with papillary thyroid carcinoma (PTC), 3 with anaplastic thyroid carcinoma (ATC), and 14 with medullary thyroid carcinoma (MTC). Results. GAs were detected in 93% (54/58) of PAYA cases, with a mean of 1.4 GAs per case. In addition to BRAF V600E mutations, detected in 46% (19/41) of PAYA PTC cases and in 1 of 3 AYA ATC cases, oncogenic fusions involving RET, NTRK1, NTRK3, and ALK were detected in 37% (15/41) of PAYA PTC and 33% (1/3) of AYA ATC cases. Ninety‐three percent (13/14) of MTC patients harbored RET alterations, including 3 novel insertions/deletions in exons 6 and 11. Two of these MTC patients with novel alterations in RET experienced clinical benefit from vandetanib treatment. Conclusion. CGP identified diverse clinically relevant GAs in PAYA patients with thyroid carcinoma, including 83% (34/41) of PTC cases harboring activating kinase mutations or activating kinase rearrangements. These genomic observations and index cases exhibiting clinical benefit from targeted therapy suggest that young patients with advanced thyroid carcinoma can benefit from CGP and rationally matched targeted therapy. Implications for Practice. The detection of diverse clinically relevant genomic alterations in the majority of pediatric, adolescent, and young adult patients with thyroid carcinoma in this study suggests that comprehensive genomic profiling may be beneficial for young

Ultra high risk of psychosis on committal to a young offender prison: an unrecognised opportunity for early intervention

PubMed Central

2012-01-01

Background The ultra high risk state for psychosis has not been studied in young offender populations. Prison populations have higher rates of psychiatric morbidity and substance use disorders. Due to the age profile of young offenders one would expect to find a high prevalence of individuals with pre-psychotic or ultra-high risk mental states for psychosis (UHR). Accordingly young offender institutions offer an opportunity for early interventions which could result in improved long term mental health, social and legal outcomes. In the course of establishing a mental health in-reach service into Ireland’s only young offender prison, we sought to estimate unmet mental health needs. Methods Every third new committal to a young offenders prison was interviewed using the Comprehensive Assessment of At-Risk Mental States (CAARMS) to identify the Ultra High Risk (UHR) state and a structured interview for assessing drug and alcohol misuse according to DSM-IV-TR criteria, the Developmental Understanding of Drug Misuse and Dependence - Short Form (DUNDRUM-S). Results Over a twelve month period 171 young male offenders aged 16 to 20 were assessed. Of these 39 (23%, 95% confidence interval 18% to 30%) met UHR criteria. UHR states peaked at 18 years, were associated with lower SOFAS scores for social and occupational function and were also associated with multiple substance misuse. The relationship with lower SOFAS scores persisted even when co-varying for multiple substance misuse. Conclusions Although psychotic symptoms are common in community samples of children and adolescents, the prevalence of the UHR state in young offenders was higher than reported for community samples. The association with impaired function also suggests that this may be part of a developing disorder. Much more attention should be paid to the relationship of UHR states to substance misuse and to the health needs of young offenders. PMID:22863073

We aimed to identify and characterize the food environments from which young people obtain food and to explore associations between the type of food environment and food intakes. Young people (n = 86, mean age 17 years; combined data of two sequential pilot studies (collected in 2008-09) and a study conducted in 2011-12) recorded in 4-day self-complete food diaries what food they consumed and where food was sourced. Nutrient, fruit and vegetable intake was calculated according to the source of food, categorized using a food environment classification tool. Over 4 days, respondents sourced food from an average of 4.3 different food environments. Home food was used daily and was more favourable in terms of nutrient profile than out-of-home food. Food sourced from specialist outlets, convenience stores and retail bakers had the highest energy density. Food from retail bakers and 'takeaway and fast food' outlets were the richest sources of fat while vending machines and convenience stores had the highest percentage of energy from sugar. This work provides details of 'where' young people obtain food and the nutritional consequences of choosing those food environments. While home food was a significant contributor to total dietary intake, food was obtained from a broad range of environments; particularly takeaway, fast food and education establishments. © The Author 2016.

This cross-sectional study aimed to map the functional profile of individuals with dyskinetic cerebral palsy (CP), to determine interrelationships between the functional classification systems, and to investigate the relationship of functional abilities with dystonia and choreoathetosis severity. Fifty-five children (<15y) and young people (15-22y) (30 males, 25 females; mean age 14y 6mo, standard deviation 4y 1mo) with dyskinetic CP were assessed using the Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), Communication Function Classification System (CFCS), Eating and Drinking Ability Classification System (EDACS), and Viking Speech Scale (VSS), as well as the Dyskinesia Impairment Scale. Over 50 per cent of the participants exhibited the highest limitation levels in GMFCS, MACS, and VSS. Better functional abilities were seen in EDACS and CFCS. Moderate to excellent interrelationship was found among the classification scales. All scales had significant correlation (r s =0.65 - 0.81) with dystonia severity except for CFCS in the young people group. Finally, only MACS (r s =0.40) and EDACS (r s =0.55) in the young people group demonstrated significant correlation with choreoathetosis severity. The need for inclusion of speech, eating, and drinking in the functional assessment of dyskinetic CP is highlighted. The study further supports the strategy of managing dystonia in particular at a younger age followed by choreoathetosis in a later stage. © 2017 Mac Keith Press.

We present new high angular resolution near-infrared spectroscopic observations of the nuclear star cluster surrounding the Milky Way's central supermassive black hole. Using the integral-field spectrograph OSIRIS on Keck II behind the laser-guide-star adaptive optics system, this spectroscopic survey enables us to separate early-type (young, 4-6 Myr) and late-type (old, >1 Gyr) stars with a completeness of 50% down to K' = 15.5 mag, which corresponds to ~10 M ⊙ for the early-type stars. This work increases the radial extent of reported OSIRIS/Keck measurements by more than a factor of three from 4'' to 14'' (0.16 to 0.56 pc), along the projected disk of young stars. For our analysis, we implement a new method of completeness correction using a combination of star-planting simulations and Bayesian inference. We assign probabilities for the spectral type of every source detected in deep imaging down to K' = 15.5 mag using information from spectra, simulations, number counts, and the distribution of stars. The inferred radial surface-density profiles, Σ(R)vpropR -Γ, for the young stars and late-type giants are consistent with earlier results (Γearly = 0.93 ± 0.09, Γlate = 0.16 ± 0.07). The late-type surface-density profile is approximately flat out to the edge of the survey. While the late-type stellar luminosity function is consistent with the Galactic bulge, the completeness-corrected luminosity function of the early-type stars has significantly more young stars at faint magnitudes compared with previous surveys with similar depth. This luminosity function indicates that the corresponding mass function of the young stars is likely less top-heavy than that inferred from previous surveys.

Few studies have examined the possible cardiometabolic consequences of World Trade Center-related exposures on children who lived and/or attended school near the disaster site. Our objective was to compare cardiometabolic profiles of participants in the World Trade Center Health Registry (WTCHR) with a matched comparison group. We evaluated WTCHR enrollees who resided in New York City and were born between September 11, 1993 and September 10, 2001, and a matched comparison group. We assessed exposure to dust cloud, home dust, as well as traumatic exposure, and associations with blood pressure, arterial wall stiffness, body mass index (BMI), total cholesterol, triglycerides, HDL, and LDL. A total of 402 participants completed the study, 222 in the comparison group and 180 in the WTCHR group. In multivariable regression analysis, after adjusting for relevant confounders we detected a weak association between participation in the WTCHR group and lower BMI (-1.12kg/m 2 , 95% CI -2.11, -0.12; p = 0.03), which became non-significant after adjusting for multiple comparisons. With respect to traumatic and psychosocial exposures, the only association that persisted in our multivariable model, below our predefined level of significance, was between post-traumatic stress disorder and higher BMI (2.06kg/m2, 95% CI 0.37, 3.74; p = 0.02). Our findings do not support an association between self-reported exposures to the WTC disaster and adverse cardiometabolic profile. However, further longitudinal studies may better inform the full extent of WTC-related conditions associated with exposure to the disaster. Copyright © 2017 Elsevier Inc. All rights reserved.

Psychological profile of pedophiles and child molesters.

PubMed

Murray, J B

2000-03-01

Pedophiles and child molesters share some characteristics. Most are male, and they can be heterosexual, homosexual, or bisexual. Some prefer adult sex partners but choose children because they are available and vulnerable. The sexual abuse perpetrated may be a 1-time incident and may consist only of fondling. Penetration is unlikely with young children. Perpetrators' ages range from teens to midlife. Most victims are girls, and the perpetrator usually is a relative, friend, or neighbor. The home of the victim is often the setting for the incident. When boys are victims, sexual abuse may take place outside the home, and perpetrators may be strangers. Perpetrators of sexual abuse of children often claim that they themselves were victims of childhood sexual abuse. Psychological profiles are helpful but are compromised partly because many perpetrators are prisoners and control groups are lacking for this research.

DK phocomelia/von Voss Cherstvoy syndrome is a rare condition characterized by upper limb and urogenital abnormalities and various brain anomalies. Previously reported cases have noted significant developmental delays, although no formal testing of cognitive abilities has been reported. In this paper we describe results from a comprehensive neuropsychological evaluation of a 12-year-old male with DK phocomelia syndrome. Test findings indicated mild impairment in intellectual functioning, with more significant impairment in adaptive skills and academic achievement. The neuropsychological profile converged with neurological findings, showing a distinct pattern of strengths and weaknesses that suggests functional compromise of posterior brain regions with relatively well-preserved functioning of more anterior regions. Specifically, impairments were evident in perceptual reasoning, visual perception, and visuomotor integration, whereas normal or near normal functioning was evident in memory, receptive language, social cognition, attention, and most aspects of executive functioning. To our knowledge this is the first report to describe the neurocognitive profile of an individual with DK phocomelia syndrome. © 2015 Wiley Periodicals, Inc.

During transition to adulthood young adults with disabilities are at risk of experiencing limitations due to changing physical and social requirements. To determine whether young adults with transversal upper limb reduction deficiency (tULRD) have experienced limitations in various domains of participation during transition to adulthood and how they dealt with these limitations. Fifteen participants (mean age 21.4 years) with tULRD. A qualitative study was performed using a semi-structured interview based on the Rotterdam Transition Profile to identify the limitations experienced in participation domains. Almost all the participants reported difficulties in finding a suitable study or job. Most young adults were convinced they were suitable for almost any study or job, but their teachers and potential employers were more reserved. Few difficulties were reported on the domains leisure activities, intimate relationships/sexuality, housing/housekeeping and transportation. Participants preferred to develop their own strategies for dealing with limitations. Various aids, adaptations and prostheses were used to overcome limitations. Rehabilitation teams were infrequently consulted for advice in solving transitional problems. Young adults with tULRD experience limitations mainly in choosing and finding a suitable study or job. Rehabilitation teams may play a more extensive role in supporting individuals with transitional problems. Implications for rehabilitation Most young adults with transversal upper limb reduction deficiency (tULRD) experience limitations in study and job selection during transition to adulthood, but they do not consult the rehabilitation team. Assessment of abilities in relation to job interests and practicing job specific bimanual activities may be helpful for young adults with a tULRD. How the rehabilitation teams can meet the needs of young adults with tULRD during transitional phases, when autonomy is of growing importance, should be investigated

Meteoric 10Be in soil profiles - A global meta-analysis

USGS Publications Warehouse

Graly, Joseph A.; Bierman, Paul R.; Reusser, Lucas J.; Pavich, Milan J.

2010-01-01

In order to assess current understanding of meteoric 10Be dynamics and distribution in terrestrial soils, we assembled a database of all published meteoric 10Be soil depth profiles, including 104 profiles from 27 studies in globally diverse locations, collectively containing 679 individual measurements. This allows for the systematic comparison of meteoric 10Be concentration to other soil characteristics and the comparison of profile depth distributions between geologic settings. Percent clay, 9Be, and dithionite-citrate extracted Al positively correlate to meteoric 10Be in more than half of the soils where they were measured, but the lack of significant correlation in other soils suggests that no one soil factor controls meteoric 10Be distribution with depth. Dithionite-citrate extracted Fe and cation exchange capacity are only weakly correlated to meteoric 10Be. Percent organic carbon and pH are not significantly related to meteoric 10Be concentration when all data are complied.The compilation shows that meteoric 10Be concentration is seldom uniform with depth in a soil profile. In young or rapidly eroding soils, maximum meteoric 10Be concentrations are typically found in the uppermost 20 cm. In older, more slowly eroding soils, the highest meteoric 10Be concentrations are found at depth, usually between 50 and 200 cm. We find that the highest measured meteoric 10Be concentration in a soil profile is an important metric, as both the value and the depth of the maximum meteoric 10Be concentration correlate with the total measured meteoric 10Be inventory of the soil profile.In order to refine the use of meteoric 10Be as an estimator of soil erosion rate, we compare near-surface meteoric 10Be concentrations to total meteoric 10Be soil inventories. These trends are used to calibrate models of meteoric 10Be loss by soil erosion. Erosion rates calculated using this method vary based on the assumed depth and timing of erosional events and on the reference data selected.

A number of factors can contribute to a delayed sleep schedule. An important factor could be a daily profile of light exposure favoring a later circadian phase. This study aimed to compare light exposure between 14 young adults complaining of a delayed sleep schedule and 14 matched controls and to identify possible associations between habitual light exposure and circadian phase. Exposure to white and blue light was recorded with ambulatory monitors for 7 consecutive days. Participants also noted their daily use of light-emitting devices before bedtime. Endogenous circadian phase was estimated with the dim light melatonin onset (DLMO) in the laboratory. The amplitude of the light-dark cycle to which the subjects were exposed was smaller in delayed than in control subjects, and smaller amplitude was associated with a later DLMO. Smaller amplitude was due to both decreased exposure in the daytime and increased exposure at night. Total exposure to blue light, but not to white light, was lower in delayed subjects, possibly due to lower exposure to blue-rich outdoor light. Lower daily exposure to blue light was associated with a later DLMO. Timing of relative increases and decreases of light exposure in relation to endogenous circadian phase was also compared between the 2 groups. In delayed subjects, there was a relatively higher exposure to white and blue light 2 h after DLMO, a circadian time with maximal phase-delaying effect. Delayed participants also had higher exposure to light 8 to 10 h after DLMO, which occurred mostly during their sleep episode but may have some phase-advancing effects. Self-reported use of light-emitting devices before bedtime was higher in delayed than in control subjects and was associated with a later DLMO. This study suggests that individuals complaining of a delayed sleep schedule engage in light-related behaviors favoring a later circadian phase and a later bedtime.

Nanoindentation measurements are made on thermosetting materials using cantiever deflection vs. piezoelectric scanner position behavior determined by AFM. The spring model is used to determine mechanical properties of materials. The generalized Sneddon's equation is utilized to calculate Young's moduli for thermosetting materials at ambient conditions. Our investigations show that the force-penetration depth curves during unloading in these materials can be described accurately by a power law relationship. The results show that the accuracy of the measurements can be controlled within 7%. The above method is used to study oxidation profiles in Pl\\1R-15 polyimide. The thermo-mechanical profiles ofPNIR-15 indicate that the elastic modulus at the surface portion of the specimen is different from that at the interior of the material. It is also shown that there are two zones within the oxidized portion of the samples. Results confirm that the surface layer and the core material have substantially different properties.

To evaluate the profile of anophthalmic cavity carriers and patients' evolution with the employed treatments. Retrospective study carried out at Faculdade de Medicina de Botucatu, to evaluate the profile and the evolution of patients with anophthalmic cavity treated in our service. Data were evaluated according to the frequency of occurrence and analysis of association. Anophthalmic cavity was more frequently observed in young males, workers in activities carried on with their hands. Trauma and phthisis bulbi were the most frequent causes, with differences according to age and gender. The complications were high (57.1% of cases), the majority occurred belatedly. Trauma is still an important cause of loss of the eye. The complications during the follow-up of the patient are frequent, occurring in general, very late, which reinforces the need for periodic and prolonged monitoring of patients with anophthalmic cavity.

Purpose This study was designed to compare the effects of two different relaxation techniques, namely progressive muscle relaxation (PMR) and autogenic relaxation (AGR) on moods of young soccer players. Methods Sixteen adolescent athletes (mean age: 14.1 ± 1.3) received either PMR or AGR training. Using Profile of Mood States- Adolescents, their mood states were measured one week before relaxation training, before the first relaxation session, and after the twelfth relaxation session. Results Mixed ANOVA revealed no significant interaction effects and no significant main effects in any of the subscales. However, significant main effects for testing sessions were found for confusion, depression, fatigue, and tension subscales. Post hoc tests revealed post-intervention reductions in the confusion, depression, fatigue, and tension subscale scores. Conclusion These two relaxation techniques induce equivalent mood responses and may be used to regulate young soccer players’ mood states. PMID:22375225

Literature data reported a higher frequency of breast cancer in young women (BCYW) in developing countries. BCYW is associated with delayed diagnosis, aggressive biology and poor prognosis. However, our knowledge of biological profile, treatment received and outcome of young patients is still limited in Morocco. We propose to analyze clinicopathologic, therapeutic and prognostic features of BCYW among a series of patients native and/or inhabitant of North of Morocco. We carried out a retro-prospective study of 331 infiltrating breast cancer cases registered between January 2010 and December 2015. Details of tumor pathology, treatment and outcome were collected. Disease-Free Survival (DFS) and Overall Survival (OS) were assessed by Kaplan-Meier analysis. A total of 82 patients were diagnosed with breast cancer at the age of 40 or younger (24.8%). Median age was 36 years. More than one quarter (26%) of patients had family history of breast or ovarian cancer. Advanced stages accounted for 34.2% of cases. Median tumor diameter was 2.8 cm. Intermediate and high-grade tumors represented 47.6% and 40.2%, respectively. Nodal involvement was present in 58.5% and lymphovascular invasion was found in 47.7% of the patients. About two thirds (66.2%) of tumors were hormone receptor positive, 29.2% over-expressed HER2 receptor and 23% were triple negative. Patients underwent breast conserving surgery in 38.2% of cases, 61.7% were offered adjuvant chemotherapy and 84.6% received hormone therapy. Five-year DFS and OS were respectively 88.9% and 75.6%. Locoregional recurrence occurred in 2.8% of cases and 8.3% of patients developed distant metastases. Our findings are in accordance with previous studies that have shown a higher frequency of breast cancer among Moroccan young women. In line with literature data, clinicopathologic profile seems to be aggressive and prognosis is pejorative in our series.

Emotional contagion and trait empathy in prosocial behavior in young people: the contribution of autonomic (facial feedback) and balanced emotional empathy scale (BEES) measures.

2013-01-01

The present research investigated first the facial feedback measured by EMG (electromyography) during decisions to engage in prosocial-helping behaviors and secondly the relation between this psychophysiological correlate and emotional empathy trait in young people. Thirty young subjects were invited to choose to adopt or not a prosocial behavior in response to social interactions. An increased zygomatic and corrugator muscle activity was found in response to prosocial interventions. Moreover, a significant positive correlation was found between empathic profile and the EMG modulation. These results highlight the role of emotions and empathy in prosocial behavior, induced by an "emotional contagion effect."

Vulvovaginitis is the most common cause of gynecological complaints in young girls. Factors which cause vulvovaginitis include, among other things, low level of sexual hormones (hypoestrogenism), the anatomical proximity of the rectum and delicate vulvar skin and vaginal mucosa. Usually vulvovaginitis in young girls is caused by non-specific factors. The aim of the study was to present the most frequent causes of vulvovaginitis in young girls.

Executive functioning (EF), needed for goal-oriented behaviour, thoughts, and emotions, is important for various life domains. This study examined the relationship between family demographics and EF subcomponents. A kindergarten sample was tested on subcomponents of working memory, inhibition, and cognitive flexibility. Parents provided information on demographic variables. For 78 children both EF and demographic data were available. First, demographic profiles were identified within the sample. Two profiles were found: A low-risk profile of mainly two-biological-parent, high-income families with a highly educated mother who did not smoke during pregnancy and a high-risk profile of low-income families with a young, low-educated mother who more often smoked during pregnancy. Second, children with different demographic profiles were compared on EF subcomponents. Results indicate differential relations between family demographics and EF subcomponents: Whereas for most EF subcomponents no association with family demographics was found, high-risk children performed better on response shifting and tended to perform worse on verbal memory than low-risk children. Parenting stress decreased performance only for high-risk children. Although this study found limited impact of family demographics for EF, further longitudinal research can provide nuanced insights about which factors influence specific EF subcomponents during which developmental periods and guide targeted prevention of EF difficulties. © 2015 The British Psychological Society.

The aim of this study was to evaluate the angular photogrammetric characteristics of subjects according to the facial esthetics criteria applicable in Côte d'Ivoire. This was a horizontal study, concerning of group of young people from Côte d'Ivoire whose attractiveness and photogrammetric characteristics were assessed. The data obtained were analyzed using SPSS 20.0 statistical software. The limit of statistical significance was P<0.05. Subjects were characterized by PCA. Attractive subjects had a large mid-face section with an upturned nose (P<0.01). Attractive women had facial profiles that were more convex than men who were judged handsome. Despite the subjectivity of the notion of beauty, certain angles of the facial profile contribute to the esthetic balance of black Ivorian faces. Copyright © 2016 CEO.

Older age is associated with changes in the brain, including the medial temporal lobe, which may result in mild spatial navigation deficits, especially in allocentric navigation. The aim of the study was to characterize the profile of real-space allocentric (world-centered, hippocampus-dependent) and egocentric (body-centered, parietal lobe dependent) navigation and learning in young vs. older adults, and to assess a possible influence of gender. We recruited healthy participants without cognitive deficits on standard neuropsychological testing, white matter lesions or pronounced hippocampal atrophy: 24 young participants (18–26 years old) and 44 older participants stratified as participants 60–70 years old (n = 24) and participants 71–84 years old (n = 20). All underwent spatial navigation testing in the real-space human analog of the Morris Water Maze, which has the advantage of assessing separately allocentric and egocentric navigation and learning. Of the eight consecutive trials, trials 2–8 were used to reduce bias by a rebound effect (more dramatic changes in performance between trials 1 and 2 relative to subsequent trials). The participants who were 71–84 years old (p < 0.001), but not those 60–70 years old, showed deficits in allocentric navigation compared to the young participants. There were no differences in egocentric navigation. All three groups showed spatial learning effect (p’ s ≤ 0.01). There were no gender differences in spatial navigation and learning. Linear regression limited to older participants showed linear (β = 0.30, p = 0.045) and quadratic (β = 0.30, p = 0.046) effect of age on allocentric navigation. There was no effect of age on egocentric navigation. These results demonstrate that navigation deficits in older age may be limited to allocentric navigation, whereas egocentric navigation and learning may remain preserved. This specific pattern of spatial navigation impairment may help differentiate normal aging from

Peer Mediated Interventions (PMIs) can be incorporated into integrated early childhood and preschool settings to address socialization impairments observed in children with ASD (Katz & Girolametto, 2013). However, research examining specific PMI strategies with young preschoolers remains limited. The current study examines the efficacy of the Stay, Play, Talk PMI (English, Shafer, Goldstein, & Kaczmerek, 1997) on the social communication skills of young preschool children diagnosed with an Autism Spectrum Disorder (ASD). Each of 3 typically developing children (ages 3-5 years) was paired with a child with an ASD (ages 3-4 years). Typically developing peers were taught to Stay with their friend, Play with their friend, and Talk to their friend. The child dyads played together during two, 20-min weekly sessions for 6-8 weeks. A multiple baseline design across participants was implemented to measure the impact of the Stay Play Talk strategies on social initiations and responses characterized by non-coordinated gestures, gestures, and words. Simulation Modeling Analysis was also conducted to confirm visual analysis. All 3 typical peer buddies and all 3 target children with ASD demonstrated increases in the frequency of their responses, reaching levels that greatly exceeded baseline levels. Further, social reciprocations increased among each dyad above baseline. Social initiations remained variable across dyads. Gains were not maintained two months post intervention. Results of this study corroborated previous findings that support the usefulness of PMIs to improve social communication of young children with ASD (Chan et al., 2009) and suggest an economical, naturally occurring approach to improve social communication during early childhood. Readers will gain knowledge regarding the social communication profile of children with ASD and how this profile can negatively impact language development and peer relationships. In addition, readers will be able to identify the

Positive self-care behaviours are more likely in young people who engage with allergy support groups, but reasons for this association are not well understood. This study explored how and why young people engage with allergy support groups to identify what activities and resources are beneficial. In-depth, semi-structured interviews were conducted with young people aged 12-21 years who reported engaging with allergy support groups (in person or on-line). Interviews were audiotaped, transcribed verbatim and analysed using thematic content analysis. The 21 participants had a range of allergies; initially most joined support groups on suggestion of their parent/carer although older participants sought groups independently. Feeling included and sharing experiences with people with similar problems/challenges were highly valued. Through membership, young people reported improved self-esteem and confidence in both managing their allergies and lives generally. Information, such as allergy alerts and hard-hitting video campaigns were reported to positively influence adherence to self-care behaviours such as carrying medication which led to sustained engagement. Participants wanted greater availability of allergy support groups, and higher profiles in healthcare and educational settings, as well as through social media. Participants valued the psychological and practical support of networking with others with allergies, and described how membership improved their confidence. This study also provides insight into the ways support groups improve young people's adherence to medical advice and positive self-care behaviours; participants responded well to hard-hitting video campaigns which appeared to emphasise the severity and susceptibility of anaphylaxis. Participants identified the need for more active promotion of support groups amongst young people and their clinicians, as well as making them available in more localities.

Species profiles are literature summaries of the life history, distribution and environmental requirements of coastal fishes and invertebrates. Profiles are prepared to assist with environmental impact assessment. The Atlantic menhaden (Brevoortia tyrannus) is an important commercial fish along the Atlantic coast. In the South Atlantic Region, Atlantic menhaden spawn during winter in continental shelf waters. Adults then move inshore and northward in spring; some move into estuaries as far as the brackish-freshwater boundary. Atlantic menhaden larvae in the South Atlantic Region enter estuaries after 1 to 3 months at sea. Young fish move into the shallow regions of estuaries andmore » seem to prefer vegetated marsh habitats. Atlantic menhaden are size-selective plankton feeders as larvae, and filter feeders as juveniles and adults. Due to their large population size, individual growth rates, and seasonal movements, Atlantic menhaden annually consume and redistribute large amounts of energy and materials. They are also important prey for large game fishes such as bluefish (Pomatomus saltatrix), striped bass (Morone saxatilis), and bluefin tuna (Thunnus thynnus). The Atlantic menhaden is associated with estuarine and nearshore systems during all phases of its life cycle. Young menhaden require these food-rich habitats to survive and grown. Destruction of estuarine wetlands has decreased nursery habitat available to Atlantic menhaden and other estuarine wetlands has decreased nursery habitat available to Atlantic menhaden and other estuarine-dependent species. 115 refs., 2 figs., 2 tabs.« less

Young Stars with SALT

We present a spectroscopic and kinematic analysis of 79 nearby M dwarfs in 77 systems. All of these dwarfs are low-proper-motion southern hemisphere objects and were identified in a nearby star survey with a demonstrated sensitivity to young stars. Using low-resolution optical spectroscopy from the Red Side Spectrograph on the South African Large Telescope, we have determined radial velocities, H-alpha, lithium 6708 Å, and potassium 7699 Å equivalent widths linked to age and activity, and spectral types for all of our targets. Combined with astrometric information from literature sources, we identify 44 young stars. Eighteen are previously known members ofmore » moving groups within 100 pc of the Sun. Twelve are new members, including one member of the TW Hydra moving group, one member of the 32 Orionis moving group, 9 members of Tucana-Horologium, one member of Argus, and two new members of AB Doradus. We also find 14 young star systems that are not members of any known groups. The remaining 33 star systems do not appear to be young. This appears to be evidence of a new population of nearby young stars not related to the known nearby young moving groups.« less

BACKGROUND AND OBJECTIVES: Few studies have explored the hormonal triggers for masturbation in infants and young children. Thus, we aimed to study the sex hormones and clinical profiles of masturbating infants and young children. METHODS: This case-control study involved infants and young children who masturbate and were referred to three pediatric neurology clinics between September 2004 and 2006 (n=13), and a similar control group. All children underwent basic laboratory investigations prior to referral. Other tests included electroencephalography (n=8) and brain neuroimaging (n=9). We measured dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, free testosterone, estradiol, dehydroepiandrosterone, sex hormone-binding globulin (SHBG), and androstenedione in all participants. RESULT: The median age at the first incident was 19.5 months (range, 4-36 months); the median masturbation frequency, 4 times/day; and the median duration of each event, 3.9 min. The subjects masturbated in both prone (n=10) and supine positions (n=3); two subjects used the knee-chest position. All subjects showed facial flushing; 6, friction between the thighs; 5, sweating; 9, sleeping after the event; and 12, disturbance on interruption. EEG was abnormal in one of eight subjects tested, and neuroimages were normal in all of nine subjects examined. The case and control groups had comparable levels of all sex hormones, except estradiol, which showed significantly lower levels in the case group (P=.02). CONCLUSION: Masturbation in children seems to be associated with reduced estradiol levels, but not with other sex hormones. Further studies are needed to confirm our findings. PMID:21060161

This study examines the addictive, criminal and psychopathological profile of a sample of 59 women incarcerated in the Villabona prison in Asturias (a region in northern Spain). The instruments administered were the EuropASI, the SCL-90-R and a semi-structured interview. Results showed that the profile is a young, single women with family dependents serving an average of 5 years' imprisonment. Of the total sample, 64.4% met criteria for a substance abuse disorder. We found a statistically significant relationship between the variables use-nonuse and type of crime: women who used substances had committed the most crimes against property and against the socioeconomic order. As regards psychopathology, 44.06% of the sample fulfilled the requirements for clinical case according to Derogatis' (1994) criteria. The results of the SCL-90-R showed that the predominant psychological disorders were, in the following order, depression, somatization, obsessive-compulsive disorder and paranoid ideation. Moreover, in the group of female users, 47.4% had dual pathology. Our results revealed a statistically significant relationship between clinical case and substance use. Finally, statistically significant differences were found between the user and nonuser groups in the EuropASI severity profile. Highest scores were found for the medical, psychiatric and family areas in the user group.

OBJECTIVES: To describe the profile of patients treated in the trauma and orthopedics nursing of a trauma care referral public hospital of in the state of Bahia. METHODS: Cross-sectional study in which data were collected from medical records of patients in the period from July to December 2008. RESULTS: The profile of the patients involved was formed by subjects mostly male young subjects, victims of trauma from accidents, especially those with motorcycles or car runover. On the other hand,the most frequent traumas associated with urban violence were perforations by gunshot and stab wounds. The primary injury presented by these individuals was exposed fracture of the femur and the most common treatment was external fixation. The most frequent in-hospital complication was wound infection, which required another surgical approach. Most inpatients were discharged and only one death was reported during this period. CONCLUSION: The results of this study corroborate those from other institutions in the country, which may contribute to elaborate public policies for accidents and violence prevention.

Although studies have found that young adults who sell drugs are more likely to be involved in risky behaviors than those who do not sell drugs, there has been relatively little research that has explored heterogeneity among young adults who sell drugs. Using a pooled sample of 18 to 25 year olds from the National Survey on Drug Use and Health (2006-2010) who report past-year drug selling (N = 5,373), this study employs latent profile analysis to specify latent groups and assess the correlates of group membership. Findings indicate substantial differences among young adults who sell drugs. In particular, the analysis found four groups of drug sellers: normative (49.6%), club drug users (23.6%), polysubstance users (16.0%), and criminal offenders (10.8%). Club drug users were characterized by high levels of ecstasy and hallucinogen use, polysubstance users were more likely to be depressed and anxious, White and female than the other groups. Criminal offenders were overwhelmingly male and more likely to be comprised of African-Americans and Hispanics. RESULTS indicate that drug selling in early adulthood varies substantially. Contrary to media and popular notions most drug sellers are not involved in crime and polysubstance using drug sellers are in clear need of mental health services. Further, most drug sellers in this age range are White. Findings suggest that policy efforts that operate under the assumption of homogeneity of drug selling may be misguided.

Structure of young oceanic crust at 13°N on the East Pacific Rise from expanding spread profiles

We present the results of the analysis of expanding spread profiles (ESPs) collected on and near the axis of the East Pacific Rise at 13°N. These profiles were collected at 0, 1.1, 2.1, 3.6, and 9.5 km from the rise axis, and all but the most distant profile show a distinct low-velocity zone (LVZ) located within layer 3 of the oceanic crust. At the ridge crest, the top of the magma chamber is at the base of layer 2, while 3.6 km off axis, the roof of the LVZ is 1.1 km below the top of layer 3. The profile farthest from the ridge could possibly have a residual LVZ confined to the lower 1.5 km of the crust. The total width of the LVZ, as determined from the ESP data, is at least 6 km, and possibly much greater. This wide LVZ apparently contradicts multichannel seismic data which show cross-axis reflections from the magma chamber with a width of <5 km. We suggest that a resolution of this apparent contradiction lies in a model of the rise axis with a small and transient central magma chamber of high partial melt fraction surrounded by a much larger and permanent region of hot rock with only isolated pockets of partial melt. The ESP data are sensitive to this larger region, while the reflection data accurately map the presence or absence of the central magma chamber with its high impedance contrast. We identify the presence of a layer at the top of the oceanic crust with initial P wave velocities between 2.35 and 2.6 km/s, while the S wave velocity is estimated as being ≤0.8 km/s. The layer thickness lies between 100 and 200 m. These velocities are consistent with previous estimates for the Pacific and recent results for the Atlantic. The thickness of this layer is consistent with that of layer 2A determined from geophysical measurements at Deep Sea Drilling Project hole 504B.

Coronary heart disease (CHD) is recognized as a lifestyle-related disease and is the second leading cause of death in Japan. However, the cardiac risk factor profile of young patients with CHD has not been clarified in suburban areas of Japan. Our study aimed to determine metabolic and lifestyle risk factors in young patients and compare them with older patients living in suburban areas of Nagano Prefecture. A multicenter study was conducted in 86 young (aged less than 40 years) and 91 older (aged 50 years and over) patients diagnosed with CHD from 1992 to 2002. There was a strong association between obesity and the occurrence of CHD events in young patients (odds ratio = 3.61, P = 0.006). Lifestyle in the young patients was characterized by a lack of physical activity and regular physical activity was found to decrease the risk of the CHD events in these patients (odds ratio = 0.31, P = 0.030). In older patients, hypertension was identified as an independent risk factor for CHD events. The results of the present study have demonstrated that obesity and a lack of regular physical exercise are independent risk factors for CHD events in younger patients. Thus, the data may be useful for the effective screening of high-risk individuals and the development of educational programs for the prevention of CHD, especially in younger Japanese.

We present medium-resolution (R ∼ 7000) near-infrared echelle spectroscopic data for 36 massive young stellar objects (MYSOs) drawn from the Red MSX Source survey. This is the largest sample observed at this resolution at these wavelengths of MYSOs to date. The spectra are characterized mostly by emission from hydrogen recombination lines and accretion diagnostic lines. One MYSO shows photospheric H I absorption, a comparison with spectral standards indicates that the star is an A-type star with a low surface gravity, implying that the MYSOs are probably swollen, as also suggested by evolutionary calculations. An investigation of the Brγ line profiles shows that most are in pure emission, while 13 ± 5 per cent display P Cygni profiles, indicative of outflow, while less than 8 ± 4 per cent have inverse P Cygni profiles, indicative of infall. These values are comparable with investigations into the optically bright Herbig Be stars, but not with those of Herbig Ae and T Tauri stars, consistent with the notion that the more massive stars undergo accretion in a different fashion than lower mass objects that are undergoing magnetospheric accretion. Accretion luminosities and rates as derived from the Br γ line luminosities agree with results for lower mass sources, providing tentative evidence for massive star formation theories based on scaling of low-mass scenarios. We present Br γ/Br12 line profile ratios exploiting the fact that optical depth effects can be traced as a function of Doppler shift across the lines. These show that the winds of MYSOs in this sample are nearly equally split between constant, accelerating and decelerating velocity structures. There are no trends between the types of features we see and bolometric luminosities or near-infrared colours.

Impact of a star formation efficiency profile on the evolution of open clusters

NASA Astrophysics Data System (ADS)

Shukirgaliyev, B.; Parmentier, G.; Berczik, P.; Just, A.

2017-09-01

Aims: We study the effect of the instantaneous expulsion of residual star-forming gas on star clusters in which the residual gas has a density profile that is shallower than that of the embedded cluster. This configuration is expected if star formation proceeds with a given star-formation efficiency per free-fall time in a centrally concentrated molecular gas clump. Methods: We performed direct N-body simulations whose initial conditions were generated by the program "mkhalo" from the package "falcON", adapted for our models. Our model clusters initially had a Plummer profile and are in virial equilibrium with the gravitational potential of the cluster-forming clump. The residual gas contribution was computed based on a local-density driven clustered star formation model. Our simulations included mass loss by stellar evolution and the tidal field of a host galaxy. Results: We find that a star cluster with a minimum global star formation efficiency (SFE) of 15 percent is able to survive instantaneous gas expulsion and to produce a bound cluster. Its violent relaxation lasts no longer than 20 Myr, independently of its global SFE and initial stellar mass. At the end of violent relaxation, the bound fractions of the surviving clusters with the same global SFEs are similar, regardless of their initial stellar mass. Their subsequent lifetime in the gravitational field of the Galaxy depends on their bound stellar masses. Conclusions: We therefore conclude that the critical SFE needed to produce a bound cluster is 15 percent, which is roughly half the earlier estimates of 33 percent. Thus we have improved the survival likelihood of young clusters after instantaneous gas expulsion. Young clusters can now survive instantaneous gas expulsion with a global SFEs as low as the SFEs observed for embedded clusters in the solar neighborhood (15-30 percent). The reason is that the star cluster density profile is steeper than that of the residual gas. However, in terms of the

Increased adiposity is linked with higher risk for cardiometabolic diseases. We aimed to determine to what extent elevated body mass index (BMI) within the normal weight range has causal effects on the detailed systemic metabolite profile in early adulthood. We used Mendelian randomization to estimate causal effects of BMI on 82 metabolic measures in 12,664 adolescents and young adults from four population-based cohorts in Finland (mean age 26 y, range 16-39 y; 51% women; mean ± standard deviation BMI 24 ± 4 kg/m(2)). Circulating metabolites were quantified by high-throughput nuclear magnetic resonance metabolomics and biochemical assays. In cross-sectional analyses, elevated BMI was adversely associated with cardiometabolic risk markers throughout the systemic metabolite profile, including lipoprotein subclasses, fatty acid composition, amino acids, inflammatory markers, and various hormones (p<0.0005 for 68 measures). Metabolite associations with BMI were generally stronger for men than for women (median 136%, interquartile range 125%-183%). A gene score for predisposition to elevated BMI, composed of 32 established genetic correlates, was used as the instrument to assess causality. Causal effects of elevated BMI closely matched observational estimates (correspondence 87% ± 3%; R(2)= 0.89), suggesting causative influences of adiposity on the levels of numerous metabolites (p<0.0005 for 24 measures), including lipoprotein lipid subclasses and particle size, branched-chain and aromatic amino acids, and inflammation-related glycoprotein acetyls. Causal analyses of certain metabolites and potential sex differences warrant stronger statistical power. Metabolite changes associated with change in BMI during 6 y of follow-up were examined for 1,488 individuals. Change in BMI was accompanied by widespread metabolite changes, which had an association pattern similar to that of the cross-sectional observations, yet with greater metabolic effects (correspondence 160% ± 2

Structural parameters of young star clusters: fractal analysis

NASA Astrophysics Data System (ADS)

Hetem, A.

2017-07-01

A unified view of star formation in the Universe demand detailed and in-depth studies of young star clusters. This work is related to our previous study of fractal statistics estimated for a sample of young stellar clusters (Gregorio-Hetem et al. 2015, MNRAS 448, 2504). The structural properties can lead to significant conclusions about the early stages of cluster formation: 1) virial conditions can be used to distinguish warm collapsed; 2) bound or unbound behaviour can lead to conclusions about expansion; and 3) fractal statistics are correlated to the dynamical evolution and age. The technique of error bars estimation most used in the literature is to adopt inferential methods (like bootstrap) to estimate deviation and variance, which are valid only for an artificially generated cluster. In this paper, we expanded the number of studied clusters, in order to enhance the investigation of the cluster properties and dynamic evolution. The structural parameters were compared with fractal statistics and reveal that the clusters radial density profile show a tendency of the mean separation of the stars increase with the average surface density. The sample can be divided into two groups showing different dynamic behaviour, but they have the same dynamic evolution, since the entire sample was revealed as being expanding objects, for which the substructures do not seem to have been completely erased. These results are in agreement with the simulations adopting low surface densities and supervirial conditions.

The present study examined sex and age differences in taste sensitivity among young adult, young-old and old-old Japanese. Participants were divided into three groups comprising 477 men and 519 women in the young-old group (aged 69-71 years), 449 men and 500 women in the old-old group (aged 79-81 years), and 35 men and 35 women in the young adult group (aged 24-32 years). Recognition thresholds for the four basic tastes were measured using the 1-mL whole mouth gustatory test, in which taste solutions of the four basic tastes were tested in five concentrations. Young adults showed significantly lower recognition thresholds than the young-old group, and the young-old group showed significantly lower recognition thresholds than the old-old group. Among the young-old and old-old groups, women showed significantly lower recognition thresholds than males for sour, salty and bitter tastes, but there was no sex difference in the sweet taste threshold between the two groups. The present study confirmed that there are age and sex differences in taste sensitivity for the four basic tastes among young adult, young-old, and old-old Japanese, and that the sensitivity of sweet taste is more robust than the other tastes.

Women with polycystic ovary syndrome (PCOS) have a high prevalence of cardiovascular disease (CVD) risk factors including dyslipidemia. Lipoproteins are heterogeneous, and measurement of serum lipids provides only the size of the pool and does not predict their function or composition. Recently, high-density lipoprotein cholesterol (HDL-C) function, as determined by cholesterol efflux capacity from macrophages, has been shown to be an independent predictor of subclinical CVD. The aim of the study was to comprehensively evaluate lipoprotein profile including lipid particle size and number and cholesterol efflux capacity in PCOS to better define CVD risk. A case control study was performed at an academic PCOS center. Women with PCOS (n = 124) and geographically matched controls (n = 67) were included in the study. The primary outcome was to measure HDL-C efflux capacity by an ex vivo system involving the incubation of macrophages with apolipoprotein (Apo) B-depleted serum from subjects, and the secondary outcome was to measure lipid particle size and number using nuclear magnetic resonance spectroscopy. Women with PCOS had significantly higher body mass index and blood pressure but similar HDL-C and low-density lipoprotein cholesterol levels compared to controls. The mean ApoA1 levels were lower, and the ApoB/ApoA1 ratio was higher in PCOS subjects compared to controls (P < .01). There were no differences in ApoB levels. Women with PCOS had an 7% decrease in normalized cholesterol efflux capacity compared to controls (P < .003). Cholesterol efflux capacity in PCOS correlated with body mass index, ApoA1, HDL-C, and the presence of metabolic syndrome. In a multivariable regression model, PCOS was significantly associated with diminished cholesterol efflux. PCOS was also associated with an atherogenic profile including an increase in large very low-density lipoprotein particles, very low-density lipoprotein (VLDL) size, and small low-density lipoprotein cholesterol

Subacute subdural hematomas are a poorly individualized nosological entity, often equated clinically to chronic subdural hematomas. Yet, their neurological deterioration which is usually rapid seems to distinguish them from chronic subdural hematomas. We wanted to show this dangerousness by establishing the clinically evolving profile of the three types of subdural hematomas. This was a prospective and retrospective study of 63 subdural hematoma (18 acute, 13 subacute, and 32 chronic) patients admitted between 2012 and 2014 in the neurosurgery unit of Lomé University Hospital. Hematomas were classified according to the elapsed time after head injury and blood density on CT. The main parameter studied was the evolution of the Glasgow Coma Score (GCS) in the 3 months following the trauma, enabling to establish an evolving profile of each type of hematoma. The average age of patients was 58.1 years for chronic subdural hematomas and 47.6 years for subacute subdural hematomas. Disease duration before admission was 13.1 days for chronic against 36.6 h for subacute hematoma. The clinical profile shows acute worsening within hours during the second week for patients with subacute hematoma, while it is progressive for patients with chronic hematoma. We noted two deaths, all victims of a subacute hematoma (one operated, one patient waiting for surgery). Iso-density hematoma on CT, especially in a young person, must be considered as a predictive factor of rapid neurological aggravation suggesting an urgent care or increased monitoring by paramedics.

On studying the young.

Cottle, T J

The process of studying youth culture is examined in terms of the consequence of the social and imaginative worlds of young people and those who study them. The impressions of the young, thus found, ultimately reveal to us insights into our own past, the relationship of generations, and the meaning of maturation. The ambivalence demonstrated by so many young people is discussed along with the difficulties this produces for observations of youth. Finally, mention is made of the importance of recognizing that studies of youth accentuate the tentativeness with which the results of social psychological studies must be held, and of resisting the temptation either to dehumanize young people through social scientific inquiries, or to overromanticize them to the extent that they themselves begin to question their own worth.

Mental disorders are the leading cause of work disability among young adults. This study examined whether distinct classes could be identified among young adults on the basis of medical history before receiving a disability pension due to a mental disorder. Medical history was obtained from pension applications and attached medical certificates for 1163 individuals aged 18-34 years who, in 2008, received a disability pension due to a mental disorder. Using latent class analysis, 10 clinical and individual adversities and their associations with sex, age and diagnostic category were examined. Three classes were identified: childhood adversity (prevalence, 33%), comorbidity (23%), and undefined (44%). The childhood adversity class was characterized by adverse events and symptoms reported during childhood and it associated with depressive disorders. The comorbidity class was characterized by comorbid mental disorders, suicide attempts and substance abuse and associated with younger age and bipolar disorder. The undefined class formed no distinct profile; individuals in this class had the lowest number of adversities and it associated with psychotic disorders. The identification of subgroups characterized by childhood circumstances and comorbidity may help planning of prevention and support practices for young adults with mental disorders and risk of work disability.

Although some historical women astronomers such as Henrietta Swan Leavitt and Cecilia Payne Gaposchkin have recently become somewhat well known among the astronomical community, many others--especially those from non-Western cultures--remain a mystery even to those of us who are actively aware of and interested in the role of early women in astronomy. As part of a project to educate myself on some of these women, I started a blog series (http://ashpags.tumblr.com/tagged/lady-astronomers) to share this newfound knowledge with a population that is on average relatively young, extremely tech savvy, and generally would not consider themselves to be science-inclined. I will discuss some of the more interesting women I have profiled, as well as my observations on the efficacy of this method of history education.

Social networking sites (SNSs) form increasingly popular venues for adolescents to express their developing identity, including their sexual self. This study investigated how and to what extent early and middle adolescents display sexuality and romance on SNSs and the demographic and psychosexual factors associated with their displays. Dutch adolescents aged 11-18 years were recruited and Facebook friended. Participants' Facebook profiles were evaluated for sexual and romantic references and Facebook engagement. Participants completed a digital questionnaire measuring constructs related to romantic and sexual development. Analyses included chi-square and Student's t-tests. A total of 104 adolescents (M(age) = 15.01, 68.3% female) were Facebook friended. Of 104 profiles, 25 (24.0%) contained 67 sexual references, and 27 (26.0%) contained 204 romantic references. Sexual references were mostly posted by others and referring to others or to no one in particular, whereas romantic references were predominantly posted by and referring to the profile owner. Displayers of sexual and romantic references were, compared with nondisplayers, older, more engaged in Facebook, more sexually experienced, and perceived more of their peers as approving of sex and as sexually active. In addition, sexual displayers were more likely boys and more sexually interested. There were no differences with respect to sexual intention and sexual attitudes. A minority of young adolescents display sexual and romantic references on SNSs. References may reflect adolescents' offline sexual and romantic experiences. Yet, they may be powerful in creating behavioral norms; therefore, guidance on interpreting and displaying such messages should be promoted.

Profiling Elements of Prosody in Speech-Communication (PEPS-C) has not been used widely to assess prosodic abilities of preschool children. This study was therefore aimed at investigating typically developing 4-year-olds' performance on PEPS-C. PEPS-C was presented to 30 typically developing 4-year-olds recruited in southern Ireland. Children were judged to have completed the test if they produced analysable responses to >95% of the items. The children's scores were compared with data from typically developing 5-6-year-olds. The majority (83%) of 4-year-olds were able to complete the test. The children scored at chance or weak ability levels on all subtests. The 4-year-olds had lower scores than 5-6-year-olds in all subtests, apart from one, with the difference reaching statistical significance in 8 out of 12 subtests. The results indicate that PEPS-C could be a valuable tool for assessing prosody in young children with typical development and some groups of young children with communication disorders.

Background To assess the late adolescent psychiatric outcomes associated with a positive Child Behavior Checklist – Juvenile Bipolar Disorder Phenotype (CBCL-JBD) in children diagnosed with ADHD and followed over a 9-year period. Methods Parents of 152 children diagnosed as ADHD (ages 7–11 years) completed the CBCL. Ninety of these parents completed it again 9 years later as part of a comprehensive evaluation of Axis I and II diagnoses as assessed using semi-structured interviews. As previously proposed, the CBCL-JBD phenotype was defined as T-scores of 70 or greater on the Attention Problems, Aggression, and Anxiety/Depression subscales. Results The CBCL-JBD phenotype was found in 31% of those followed but only 4.9% of the sample continued to meet the phenotype criteria at follow up. Only two of the sample developed Bipolar Disorder by late adolescence and only one of those had the CBCL-JBD profile in childhood. The proxy did not predict any Axis I disorders. However, the CBCL-JBD proxy was highly predictive of later personality disorders. Limitations Only a subgroup of the original childhood sample was followed. Given this sample was confined to children with ADHD, it is not known whether the prediction of personality disorders from CBCL scores would generalize to a wider community or clinical population Conclusions A positive CBCL-JBD phenotype profile in childhood does not predict Axis I Disorders in late adolescence; however, it may be prognostic of the emergence of personality disorders.

Portfolio theory and the alternative decision rule of cost-effectiveness analysis: theoretical and practical considerations.

Sendi, Pedram; Al, Maiwenn J; Gafni, Amiram; Birch, Stephen

2004-05-01

Bridges and Terris (Soc. Sci. Med. (2004)) critique our paper on the alternative decision rule of economic evaluation in the presence of uncertainty and constrained resources within the context of a portfolio of health care programs (Sendi et al. Soc. Sci. Med. 57 (2003) 2207). They argue that by not adopting a formal portfolio theory approach we overlook the optimal solution. We show that these arguments stem from a fundamental misunderstanding of the alternative decision rule of economic evaluation. In particular, the portfolio theory approach advocated by Bridges and Terris is based on the same theoretical assumptions that the alternative decision rule set out to relax. Moreover, Bridges and Terris acknowledge that the proposed portfolio theory approach may not identify the optimal solution to resource allocation problems. Hence, it provides neither theoretical nor practical improvements to the proposed alternative decision rule.

This article describes the treatment of a young adult male with a concave profile, skeletal class III malocclusion because of a prognathic mandible and proclined upper incisors. The therapy included stages: 1. Pre-surgical orthodontics involving leveling and aligning of upper and lower arches, protraction of lower molars and retraction of upper incisors; 2. Surgical phase involving BSSO with mandibular setback and 3. Post-surgical orthodontics for finishing and detailing. The treatment lasted 23 months and improved facial esthetics significantly The treatment resulted in a functional occlusion with a lack of lateral cuspid guidance that could be accepted considering the difficulty of the case. Over jet and overbite are within norms.

The present study sought to inform models of risk for drugged driving through empirically identifying patterns of marijuana use, alcohol use, and related driving behaviors. Perceived dangerousness and consequences of drugged driving were evaluated as putative influences on risk patterns. We used latent profile analysis of survey responses from 897 college students to identify patterns of substance use and drugged driving. We tested the hypotheses that low perceived danger and low perceived likelihood of negative consequences of drugged driving would identify individuals with higher-risk patterns. Findings from the latent profile analysis indicated that a four-profile model provided the best model fit. Low-level engagers had low rates of substance use and drugged driving. Alcohol-centric engagers had higher rates of alcohol use but low rates of marijuana/simultaneous use and low rates of driving after substance use. Concurrent engagers had higher rates of marijuana and alcohol use, simultaneous use, and related driving behaviors, but marijuana-centric/simultaneous engagers had the highest rates of marijuana use, co-use, and related driving behaviors. Those with higher perceived danger of driving while high were more likely to be in the low-level, alcohol-centric, or concurrent engagers' profiles; individuals with higher perceived likelihood of consequences of driving while high were more likely to be in the low-level engagers group. Findings suggested that college students' perceived dangerousness of driving after using marijuana had greater influence on drugged driving behaviors than alcohol-related driving risk perceptions. These results support targeting marijuana-impaired driving risk perceptions in young adult intervention programs.

The Seminar on Young Child Nutrition: Improving Nutrition and Health Status of Young Children in Indonesia held in Jakarta on November 2009 reviewed the current nutritional and health status of young children in Indonesia and identified key nutrient deficiencies affecting their optimal growth. The continuation of child growth from fetal stage is of paramount importance; and maternal and child health should be a central consideration in policy and strategy development. Clinical management of nutrient deficiency and malnutrition, as well as strategies and education to improve feeding practices of young Indonesian children were discussed in the seminar. Relevant experiences, approaches and strategies from France, New Zealand and Malaysia were also shared and followed with discussion on how regulatory systems can support the development of health policy for young children. This report highlights important information presented at the seminar.

In order to test the impact of a given risk profile on the incidence of osteoporosis which could justify BMD measurement, and that of a low risk profile which could render it unnecessary, BMD was measured in 217 women under 72 in whom menopause had occurred at least 6 years previously and who corresponded to one of the two following profiles: high risk (A, n = 102) = BMI < 27 kg/m2, with no estrogen replacement treatment, and with at least one of the following risk factors: BMI < 20, early menopause, positive family history, no dairy products associated with tobacco consumption (> 10 cigarettes/day for > 20 years and/or alcohol consumption of > 0.5 l wine/day during > 10 years, corticotherapy of > 6 months, rickets, anorexia nervosa. Low risk (B, n = 115) = absence of characteristics of group A, BMI > 27 kg/m2 with (B+, n = 24) or without estrogen therapy (B-, n = 91). BMD was measured by DXA in 4 centers using Lunar or Hologic equipment. Results were expressed in % of the mean of the respective young adult control groups. As expected, BMD was significantly different in these two subgroups of the population. Osteoporosis was diagnosed (BMD < 75% = < -2.5 SD, according to WHO) in 72% of group A, and in 17% (B+) and 19% (B-) respectively of group B. There was no difference between the various risk factors in group A concerning their impact on BMD, but concerning incidence, low BMI and early menopause were the most frequent. The high risk profile of group A seems to justify densitometry, since it leads to the diagnosis of osteoporosis in over 70%. However, the protective profile of group B does not exclude osteoporosis (risk still 20%); only in severe obesity (BMI > 33) does it drop to 1%.

Metabolic syndrome (MetS) in young adults poses significant cardiovascular diseases (CVD) risk for later years. Parental history of CVDs is known to affect the prevalence of CVD risk in adulthood. In sub-Saharan Africa, the burden of MetS in young adults and its relationship with parental CVDs is largely unknown. We studied the gender-specific prevalence of MetS and its association with parental history of diabetes, hypertension and CVDs in young adults resident in urban Ghana. In a cross-sectional design, 364 young adults aged 20-30 years were randomly recruited from students of University of Ghana. A structured questionnaire was used to collect data on demography, lifestyle, medical and parental medical history. Anthropometric indices and blood pressures were measured. Fasting blood samples were collected to measure plasma levels of glucose, lipid profile, urea and creatinine. MetS was defined according to the Joint Scientific Statement criteria. The prevalence of MetS was 12.4%, higher in females than male participants (18.4% vs 5.7, p = 0.019). Female participants had higher levels of all the components of MetS than the male participants. Compared to participants with no history of parental CVDs, participants with parental CVDs had a higher proportion of abdominal obesity. A positive history of parental CVDs was associated with increase in odds of MetS [OR (95% CI): 1.23 (1.12-3.04), p = 0.037]. In our study population, there is relatively high prevalence of MetS; higher in females compared to male participants. Parental history of CVDs was associated with MetS.

Young carer awareness, identification and referral.

PubMed

Sprung, Sally; Laing, Michelle

Young carers often provide care because they have always done so for the people they care about, and because they believe that the care recipient could not manage without them. For many young carers, looking after their own health, combining caring with schoolwork, getting access to training or having time off from carer duties can be a major challenge ( Department of Health [DH], 2008 ). This paper presents evidence from a literature review that builds a substantial body of knowledge to suggest that community nursing teams must develop supportive approaches towards increasing an awareness of young carers' needs. Identification of young carers by community nurses will encourage referral to appropriate services and agencies. The aim of this study was to appraise, for the Queen's Nursing Institute, the published evidence base to explore young carers' needs and how community nurses could support young carers' needs in England. Databases were systematically searched. Title and abstract reviews found 606 potential studies (see Figure 1 ), which were identified around topics corresponding to the headings of three distinct categories: mental health and wellbeing; education needs and resilience; and development of coping strategies. Full-text review resulted in 26 publications that met the study's inclusion criteria. The results of this work show that there is a scarcity of publications around the community nursing needs of young carers. However, studies consistently report young carers are hidden from view and have a significant requirement for support and information. Therefore, effective ways of delivering community nursing support and information to young carers needs to be developed by service providers as a matter of priority, and implemented to give the support that young carers need.

Humulus lupulus L., commonly named hop, is well-known for its sedative and estrogenic activity. While hop cones are widely characterized, only few works have been carried out on the young shoots of this plant. In the light of this, the aim of this study was to identify for the first time the flavonoids present in young hop shoots and to compare the composition of samples harvested from different locations in Northern Italy with their antioxidant activity. The samples were extracted by means of dynamic maceration with methanol. The HPLC-UV/DAD, HPLC-ESI-MS and MS 2 analysis were carried out by using an Ascentis C 18 column (250×4.6mm I.D., 5μm), with a mobile phase composed of 0.1M formic acid in both water and acetonitrile, under gradient elution. Quercetin and kaempferol glycosides were the main compounds identified and quantified in hop shoot extracts. Total flavonols ranged from 2698±185 to 517±48μg/g (fresh weight). The antioxidant activity was determined by means of the radical scavenging activity assay against diphenylpicrylhydrazyl (DPPH) and by using a photochemiluscence assay with a Photochem ® apparatus. The results showed that hop shoots represent a new source of flavonols; therefore, they can be useful for a possible incorporation in the diet as a functional food or applied in the nutraceutical ambit.

To identify young parents' perceptions and experiences of a parenting support programme, run by a non-government organisation, which provided both community group-based, and one-on-one home visiting, support. A qualitative descriptive study was conducted in one of the most socio-economically disadvantaged areas of Sydney, NSW; this is also an area with one of the highest percentage of births among young parents. Young parents were eligible to participate whether they attended one of the parenting groups and/or received professional home visiting through the young parents programme. Eighteen young women were interviewed, and a further ten participated in a focus group. Thematic analysis of the focus groups and interviews was undertaken. Four themes were identified in the analysis: 'someone I know and trust', 'we just talk about anything and everything', 'doing the personal' and 'getting out and relaxing'. These themes were linked through the common thread of relationships; the relationships between themselves and other young mothers, and with the workers on the programme. The characteristics of the person with whom they had a relationship, the type of relationship, the content of their interactions and the benefits of these relationships were all important. This study is limited by the small sample size and the 'low risk' status of the young parents who engaged in the programme. This study demonstrated not only the importance for young parents of all forms of interaction, whether it is one-on-one, in a group or social networking; but most importantly, the benefits of having someone to talk to. © 2012 The Authors.

Breast cancer in young women is more aggressive with a poorer prognosis and overall survival compared to older women diagnosed with the disease. Despite recent research, the underlying biology and molecular alterations that drive the aggressive nature of breast tumors associated with breast cancer in young women have yet to be elucidated. In this study, we performed transcriptomic profile and network analyses of breast tumors arising in Middle Eastern women to identify age-specific gene signatures. Moreover, we studied molecular alterations associated with cancer progression in young women using cross-species comparative genomics approach coupled with copy number alterations (CNA) associated with breast cancers from independent studies. We identified 63 genes specific to tumors in young women that showed alterations distinct from two age cohorts of older women. The network analyses revealed potential critical regulatory roles for Myc, PI3K/Akt, NF-κB, and IL-1 in disease characteristics of breast tumors arising in young women. Cross-species comparative genomics analysis of progression from pre-invasive ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC) revealed 16 genes with concomitant genomic alterations, CCNB2, UBE2C, TOP2A, CEP55, TPX2, BIRC5, KIAA0101, SHCBP1, UBE2T, PTTG1, NUSAP1, DEPDC1, HELLS, CCNB1, KIF4A, and RRM2, that may be involved in tumorigenesis and in the processes of invasion and progression of disease. Array findings were validated using qRT-PCR, immunohistochemistry, and extensive in silico analyses of independently performed microarray datasets. To our knowledge, this study provides the first comprehensive genomic analysis of breast cancer in Middle Eastern women in age-specific cohorts and potential markers for cancer progression in young women. Our data demonstrate that cancer appearing in young women contain distinct biological characteristics and deregulated signaling pathways. Moreover, our integrative genomic and cross

Studies investigating the relation between risk profiles and cardiovascular disease have measured risk at baseline only. We investigated maintenance and changes of risk profiles over time and their potential impact on incident cardiovascular disease. Population-based cohort study. Risk factors were measured at baseline (1987-1991) among 5574 cardiovascular disease-free adults aged 20-59 years. They were classified into four risk categories according to smoking status, presence of diabetes and widely accepted cut-off values for blood pressure, total cholesterol/HDL-ratio and body mass index. Categories were subdivided (maintenance, deterioration, improvement) based on risk factor levels at six and 11 years of follow-up. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for cardiovascular disease incidence 5-10 years following the risk-change period were fitted using Cox proportional hazards models. Only 12% of participants were low risk at baseline, and only 7% maintained it. Participants who maintained a low risk profile over 11 years had seven times lower risk of cardiovascular disease (HR: 0.14, 95% CI: 0.05-0.41) than participants with long-term high risk profile, whereas those low risk at baseline whose profile deteriorated had three times lower risk (HR: 0.36, 95% CI: 0.18-0.71). Our results suggest that, within each baseline risk profile group, compared with a stable profile, improving profiles may be associated with up to two-fold lower HRs, and deteriorating profiles with about two-fold higher HRs. Our study, using long-term risk profiles, demonstrates the full benefits of low risk profile. These findings underscore the importance of achieving and maintaining low risk from young adulthood onwards. © The European Society of Cardiology 2014.

Self-rated quality of life among the young unemployed and the young in work in northern Sweden.

Hultman, Barbro; Hemlin, Sven

2008-01-01

This study analysed self-assessed quality of life (QoL), using a QoL questionnaire (Hörnquist's QLcs) covering life spheres, somatic health, mental well-being, cognitive ability, social and family life, activity, financial situation, meaning in life and a global score "entire life", for young people aged 18-24 in a population-based cross-sectional study in northern Sweden. Of these, 651 were unemployed and 2802 were in work (employed, students and in military service). Results showed that the young unemployed exhibited poorer QoL than the young in work and the greatest difference was found regarding their financial situation. Young men rated somatic health and mental well-being higher than young women. However, QoL in other essential domains was rated higher by young women in work. Close friends and money reserve were important for all participants, no matter whether they were employed or not. The risk of being young and unemployed was greater if the person had a worse financial situation, shorter education, and fewer leisure activities with other people. Finally, it was concluded that while QoL is poorer when in unemployment - both for the young and those who are older (aged 25-64) - psychological well-being, in contrast to several previous studies, is even poorer for young people than for those who are older. This is worrying in a public health perspective and could have implications for unemployment policies for younger and less well-educated age groups.

Self-harm among young people remains largely stigmatised and misunderstood. Parents have been identified as key facilitators in the help-seeking process, yet they typically report feeling ill-equipped to support the young person in their care. The aim of this review was to examine the perspectives of both young people (aged 12–28) and parents and to develop the conceptual framework for a future qualitative study. A systematic search of MEDLINE and PsycINFO was performed to identify articles that focused on the experiences of family members and young people related to managing the discovery of self-harm. Fourteen articles were included for review. Four addressed the perspectives of young people and 10 reported on the impact of adolescent self-harm on parents. The impact of self-harm is substantial and there exists a discrepancy between the most common parental responses and the preferences of young people. In addition, parents are often reluctant to seek help for themselves due to feelings of shame and guilt. This highlights the need for accessible resources that seek to alleviate parents’ distress, influence the strategies implemented to manage the young person’s self-harm behaviour, reduce self-blame of family members, and increase the likelihood of parental help seeking.

Fibrolamellar hepatocellular carcinoma (FLC) is a rare subtype of liver cancer occurring mostly in children and young adults. We have shown that FLC comprises two separate entities: pure (p-FLC) and mixed-FLC (m-FLC), differing in clinical presentation and course. We show that p-FLCs have a distinct gene expression signature different from that of m-FLCs, which have a signature similar to that of classical hepatocellular carcinomas. We found p-FLC profiles to be unique among 263 profiles related to diverse tumoral and nontumoral liver samples. We identified two distinct molecular subgroups of p-FLCs with different outcomes. Pathway analysis of p-FLCs revealed ERBB2 overexpression and an up-regulation of glycolysis, possibly leading to compensatory mitochondrial hyperplasia and oncocytic differentiation. Four of the sixteen genes most significantly overexpressed in p-FLCs were neuroendocrine genes: prohormone convertase 1 (PCSK1); neurotensin; delta/notch-like EGF repeat containing; and calcitonin. PCSK1 overexpression was validated by immunohistochemistry, yielding specific, diffuse staining of the protein throughout the cytoplasm, possibly corresponding to a functional form of this convertase. p-FLCs have a unique transcriptomic signature characterized by the strong expression of specific neuroendocrine genes, suggesting that these tumors may have a cellular origin different from that of HCC. Our data have implications for the use of genomic profiling for diagnosis and selection of targeted therapies in patients with p-FLC. © 2014 by the American Association for the Study of Liver Diseases.

This study examined adult age differences in reflexive orienting to two types of uninformative spatial cues: central arrows and peripheral onsets. In two experiments using a Posner cuing task, young adults (ages 18 – 28 yrs), young-old adults (ages 60 – 74 yrs), and old-old adults (ages 75 – 92 yrs) responded to targets that were preceded 100–1,000 ms earlier by a central arrow or a peripheral abrupt onset. In Experiment 1, the cue remained present upon target onset. Facilitation effects at early cue-target stimulus onset asynchronies (SOAs) were prolonged in duration for the two older groups relative to the young adults. At later cue-target SOAs, inhibition of return (IOR) that was initiated by peripheral onset cues was observed in the performance of young adults but not in that of the two older groups. In Experiment 2, the cue was presented briefly and removed prior to target onset. The change in cue duration minimized age differences (particularly for young-old adults) in facilitation effects and led to IOR for all three age groups. The findings are consistent with the idea that attentional control settings change with age, with higher settings for older adults leading to delayed disengagement from spatial cues. PMID:21394555

Chlamydia trachomatis screening in young women.

2011-10-01

As the number of chlamydia screening programmes implemented worldwide increases, we summarize current understanding of the epidemiology, natural history, and management of chlamydia, focusing on screening in young women. Chlamydia diagnoses continue to rise, with young women at high risk. Recently published trials show that the risk of serious reproductive health outcomes is lower than previously thought. They illustrate that significant barriers - both practical and cultural - remain to engaging young people and health professionals in routine testing for sexually transmitted infections. Chlamydia control efforts have driven innovative approaches to testing including new approaches to engaging young people in discussions of sexual health and screening accessed via the Internet. Chlamydia is highly prevalent among young women and may cause serious reproductive sequelae. Gaps in our knowledge of the epidemiology, natural history and immunology of this organism continue to hamper efforts to control it. Sexual health promotion and screening of young people remain the mainstay of population control, although there is as yet no strong evidence of health screening benefits. Control efforts will require new strategies to engage young people and health professionals to normalize sexual health testing. (C) 2011 Lippincott Williams & Wilkins, Inc.

A young bipolar outflow from IRAS15398-3359

2015-08-01

The Class 0 protostar IRAS 15398-3359 is located in the Lupus I cloud at a distance of 155 pc. The source is known to harbour a molecular outflow, but the region has not attracted much interest until recently. IRAS 15398 is known to show interesting chemical signatures and being one of the very nearby, young outflow sources makes it an excellent target for detailed studies of the gas kinematics of different species.We present observations of several molecular species, carried out with the Submillimeter Array and ALMA, towards the IRAS 15398 outflow. The analysis of CO emission show obvious signs of episodic mass ejections, with a dynamical time scale between the knots in the jet, of the order 100 years. This is consistent with recent ALMA results where luminosity outbursts are estimated to occur on similar time-scales. The physical properties of the outflow, such as mass, momentum, momentum rate, mechanical luminosity, kinetic energy and mass-loss rate are estimated at relatively low values. We argue that this source is of a very young age, possibly younger than ~1000 years. This is consistent with recent studies of the kinematics of the inner envelope/disk. The observed line profiles were compared to full 3D radiative transfer models of the source, constructed with the Line Modelling Engine (LIME). The observed line shapes can only be understood when considering several distinctly different physical components, viz. the outflow cavity, the infalling envelope and the surrounding cloud material. This allows us to put quantitative constraints on the kinematics of the material close to the central source.

Observations of fault zone heterogeneity effects on stress alteration and slip nucleation during a fault reactivation experiment in the Mont Terri rock laboratory, Switzerland

NASA Astrophysics Data System (ADS)

Nussbaum, C.; Guglielmi, Y.

2016-12-01

The FS experiment at the Mont Terri underground research laboratory consists of a series of controlled field stimulation tests conducted in a fault zone intersecting a shale formation. The Main Fault is a secondary order reverse fault that formed during the creation of the Jura fold-and-thrust belt, associated to a large décollement. The fault zone is up to 6 m wide, with micron-thick shear zones, calcite veins, scaly clay and clay gouge. We conducted fluid injection tests in 4 packed-off borehole intervals across the Main Fault using mHPP probes that allow to monitor 3D displacement between two points anchored to the borehole walls at the same time as fluid pressure and flow rate. While pressurizing the intervals above injection pressures of 3.9 to 5.3 MPa, there is an irreversible change in the displacements magnitude and orientation associated to the hydraulic opening of natural shear planes oriented N59 to N69 and dipping 39 to 58°. Displacements of 0.01 mm to larger than 0.1 mm were captured, the highest value being observed at the interface between the low permeable fault core and the damage zone. Contrasted fault movements were observed, mainly dilatant in the fault core, highly dilatant-normal slip at the fault core-damage zone interface and low dilatant-strike-slip-reverse in the damage-to-intact zones. First using a slip-tendency approach based on Coulomb reactivation potential of fault planes, we computed a stress tensor orientation for each test. The input parameters are the measured displacement vectors above the hydraulic opening pressure and the detailed fault geometry of each intervals. All measurements from the damage zone can be explained by a stress tensor in strike-slip regime. Fault movements measured at the core-damage zone interface and within the fault core are in agreement with the same stress orientations but changed as normal faulting, explaining the significant dilatant movements. We then conducted dynamic hydromechanical simulations

Spine problems in young athletes.

2012-01-01

As the number of young people involved in sports activities increases, acute and chronic back pain has become more common. With a careful medical history and physical examination, along with the judicious use of imaging modalities, the causes of back pain can be correctly diagnosed and treated so that young athletes can quickly return to sports participation. Although most back pain in these young patients is muscular in origin, findings that should trigger increased concern include night pain, marked hamstring tightness, pain with lumbar spine hyperextension, or any neurologic finding. When recently developed vague back pain is present, a delay in radiographic imaging is warranted. With new back pain after trauma, AP and lateral radiographs of the symptomatic spinal area are indicated. CT, bone scans, and MRI should be reserved for special circumstances. Spondylolysis is the most common bony cause of back pain in young athletes. Spondylolysis can be treated with activity limitation, a specific exercise program, a thoracolumbar orthosis, and/or surgery. Treatment should be based on the amount of pain as well as the desire of the young athlete to continue in the sports activity that caused the pain. Other significant causes of back pain that require more extensive treatment in these young athletes include spondylolisthesis, lumbar disk disorders, and sacral stress fractures. It is anticipated that nearly all young athletes can return to sports activity after successful treatment. Even if surgical treatment is needed, return to all sports is expected, with the occasional exception of collision sports.

Searching mixed DNA profiles directly against profile databases.

Bright, Jo-Anne; Taylor, Duncan; Curran, James; Buckleton, John

2014-03-01

DNA databases have revolutionised forensic science. They are a powerful investigative tool as they have the potential to identify persons of interest in criminal investigations. Routinely, a DNA profile generated from a crime sample could only be searched for in a database of individuals if the stain was from single contributor (single source) or if a contributor could unambiguously be determined from a mixed DNA profile. This meant that a significant number of samples were unsuitable for database searching. The advent of continuous methods for the interpretation of DNA profiles offers an advanced way to draw inferential power from the considerable investment made in DNA databases. Using these methods, each profile on the database may be considered a possible contributor to a mixture and a likelihood ratio (LR) can be formed. Those profiles which produce a sufficiently large LR can serve as an investigative lead. In this paper empirical studies are described to determine what constitutes a large LR. We investigate the effect on a database search of complex mixed DNA profiles with contributors in equal proportions with dropout as a consideration, and also the effect of an incorrect assignment of the number of contributors to a profile. In addition, we give, as a demonstration of the method, the results using two crime samples that were previously unsuitable for database comparison. We show that effective management of the selection of samples for searching and the interpretation of the output can be highly informative. Copyright © 2013 Elsevier Ireland Ltd.

The pharmacokinetics of abacavir and its metabolites were investigated in 30 human immunodeficiency virus (HIV)-infected adolescents and young adults 13-25 years of age, equally divided into two groups: <18 years of age and ≥18 years of age. All the subjects received the recommended adult dose of 300 mg twice daily. The area under the plasma concentration-time curve (AUC) and half-life of abacavir did not differ significantly between the age groups or by gender or race, and there were only modest associations of age with apparent abacavir clearance and with volume of distribution. There were no significant correlations of carboxylate or glucuronide metabolite levels with age or gender, although glucuronide AUC was higher in Hispanic subjects than in African-American subjects. Zidovudine and lamivudine concentration profiles were also similar in the two age groups. A novel aspect of the study included an assessment of intracellular carbovir, zidovudine, and lamivudine triphosphate levels, and these were found to be similar in the two age-based groups. Overall, these findings suggest that current recommendations relating to adult dosages are appropriate for adolescents and young adults. PMID:19118380

Several authors emphasize the close relationship between self-esteem and athletic performance; such a relationship may raise the following question: by saying "strong" or "without any physical condition", is it a fair presentation of the individual's abilities or he reveals the most fundamental aspects of his personality, such as emotional temperament? To evaluate self-esteem, physical self and temperamental profile in a group of sportsmen, and to look for a relationship between these variables and athletic performance. We performed a cross-sectional, descriptive and analytic study in 80 young handball players of the "senior" category. We assessed self-esteem using the Rosenberg Self Esteem Scale, physical self-using the Physical Self-Inventory (PSI), and temperamental profile using the Temperament Evaluation of Memphis, Paris and San Diego Auto-questionnaire (TEMPS-A). Athletic performance was evaluated by the team coach by means of a score ranging from 1 to 10. High self-esteem was correlated to female gender (p=0.03), to an early start of physical activity (p<0.01), and certain dimensions of the physical self: perceived physical value (p=0.02), appearance (p<0.01), and the global score (p=0.01). Athletic performance was correlated to high self-esteem (p<0.01) and to two dimensions of the physical self: the global score (p=0.01) and the perceived physical value (p<0.01). Hyperthymic temperament was associated with high self-esteem (p=0.001). Good athletic performance was associated with hyperthymic (p<0.01) and cyclothymic (p<0.01) temperament. Low athletic performance was associated with depressive (p=0.04) and irritable (p=0.01) temperament. Our study shows the close relationship between selfesteem, temperamental profile and athletic performance. We suggest that the intervention of a psychiatrist or a psychologist aimed at improving sportsmen's' self-esteem might help to achieve better athletic performance. In this intervention, the individual temperamental

In the current recommendations for energy intake of different countries as well as in the international WHO recommendations for energy intake it is assumed that the elderly are less physically active than young adults. Therefore, the aim of the present study was to compare physical activity patterns and physical activity level (PAL) of young and elderly subjects. In 178 female (age 67.8+/-5.7 y, BMI 26.4+/-3.7 kg/m(2)) and 107 male (age 66.9+/-5.1 y, BMI 26.3+/-3.1 kg/m(2)) participants of the longitudinal study on nutrition and health status in an aging population of Giessen, Germany as well as in a young age group consisting of 154 women (age 24.8+/-3.0 y, BMI 21.0+/-2.2 kg/m(2)) and 68 men (age 26.8+/-3.4 y, BMI 23.3+/-2.4 kg/m(2)) different activities like occupational work, housework, gardening, walking and sports were assessed by a questionnaire. Energy expenditure of the different activities was calculated using multipliers for resting metabolic rate (RMR) according to the WHO. The same multipliers were used for young and elderly subjects. RMR was measured by indirect calorimetry after an overnight fast. PAL of the subjects was calculated as total energy expenditure divided by RMR. Young adults did more occupational work and performed more sports than elderly subjects. In contrast elderly women did more housework in comparison to young women, and elderly men walked more than young men. Both elderly women and men did more gardening than young women and men. In elderly women, PAL was significantly higher in comparison to young women, whereas PAL of young and elderly men did not differ significantly. The results indicate that despite different activity patterns, the young-old do not necessarily show a lower PAL than young subjects.

Thermal transport dynamics in the quasi-single helicity state

McKinney, I. J.; Terry, P. W.

2017-06-01

A dynamical model describing oscillations between multiple and single helicity configurations in the quasi-single helicity (QSH) state of the reversed field pinch [P. W. Terry and G. G. Whelan, Plasma Phys. Controlled Fusion 56, 094003 (2014)] is extended to include electron temperature profile dynamics. It is shown that QSH dynamics is linked to the electron temperature profile because the suppression of mode coupling between tearing modes proposed to underlie QSH also suppresses magnetic-fluctuation-induced thermal transport. Above the threshold of dominant-mode shear that marks the transition to QSH, the model produces temperature-gradient steepening in the strong shear region. Oscillations of the dominant and secondary mode amplitudes give rise to oscillations of the temperature gradient. The phasing and amplitude of temperature gradient oscillations relative to those of the dominant mode are in agreement with experiment. This provides further evidence that the model, while heuristic, captures key physical aspects of the QSH state.

We sought to identify relationship and individual psychological factors that related to four profiles of intimate partner violence (IPV) among pregnant adolescent couples: no IPV, male IPV victim only, female IPV victim only, mutual IPV, and how associations differ by sex. Using data from a longitudinal study of pregnant adolescents and partners (n = 291 couples), we used a multivariate profile analysis using multivariate analysis of covariance with between and within-subjects effects to compare IPV groups and sex on relationship and psychological factors. Analyses were conducted at the couple level, with IPV groups as a between-subjects couple level variable and sex as a within-subjects variable that allowed us to model and compare the outcomes of both partners while controlling for the correlated nature of the data. Analyses controlled for age, race, income, relationship duration, and gestational age. Among couples, 64% had no IPV; 23% male IPV victim only; 7% mutual IPV; 5% female IPV victim only. Relationship (F = 3.61, P < .001) and psychological (F = 3.17, P < .001) factors differed by IPV group, overall. Attachment anxiety, attachment avoidance, relationship equity, perceived partner infidelity, depression, stress, and hostility each differed by IPV profile (all P < .01). Attachment anxiety, equity, depression and stress had a significant IPV profile by sex interaction (all P < .05). Couples with mutual IPV had the least healthy relationship and psychological characteristics; couples with no IPV had the healthiest characteristics. Females in mutually violent relationships were at particularly high risk. Couple-level interventions focused on relational issues might protect young families from developing IPV behaviors.

Eating behaviours among young women.

1983-09-03

Disordered eating and weight-control behaviour is becoming increasingly common among adolescent girls. We studied four groups of young women aged between 15 and 27 years (106 school and university students, 50 ballet school students, 22 patients suffering from anorexia nervosa and 44 patients with bulimia). Our results suggest that most young women diet at some time and lose more than three kg in weight; that they may experience episodes of binge eating and "picking" behaviour; and that they wish to be thinner irrespective of their current body weight. Twenty per cent of young women may fulfil the criteria for an eating disorder (bulimia or anorexia nervosa) at some stage, however briefly, and about 7% abuse laxatives or diuretics in order to achieve a fashionably slim figure. We suggest that most young women may pass through a phase of what is currently called disordered eating, and that this is part of normal development and may not necessarily require treatment. The incidence of disordered eating is greater in those young women who are under pressure to maintain a low body weight.

2005-10-05

The aroma compounds of young and aged Chinese "Yanghe Daqu" liquor samples were extracted by solid phase microextraction (SPME) and analyzed by gas chromatography (GC)-olfactometry dilution analysis. The original liquor samples were diluted with deionized water to give a final alcohol content of 14% (v/v). The samples were stepwise diluted (1:1) with 14% (by volume) ethanol-water solution and then extracted by headspace SPME. The samples were preequilibrated at 50 degrees C for 15 min and extracted with stirring at the same temperature for 30 min prior to injection into GC. The aroma compounds were identified by both GC-MS and GC-olfactometry using DB-Wax and DB-5 columns. The results suggested that esters were the major contributors to Yanghe Daqu liquor aroma. Ethyl hexanoate, ethyl butanoate, and ethyl pentanoate had very high flavor dilution values in both young and aged liquors (FD > 8192). Methyl hexanoate, ethyl heptanoate, ethyl benzoate, and butyl hexanoate could also be very important because of their high flavor dilution values (FD > or = 256). Moreover, two acetals, 1,1-diethoxyethane and 1,1-diethoxy-3-methylbutane, also were shown high flavor dilution values in Yanghe Daqu liquors (FD > or = 256). Other aroma compounds having moderate flavor dilution values included acetaldehyde, 3-methylbutanol, and 2-pentanol (FD > or = 32). Comparing young and aged liquors, the aroma profiles were similar, but the aroma compounds in the aged sample had higher flavor dilution values than in the young ones.

Barriers to modern contraceptive methods uptake among young women in Kenya: a qualitative study.

Young women in Kenya experience a higher risk of mistimed and unwanted pregnancy compared to older women. However, contraceptive use among youth remains low. Known barriers to uptake include side effects, access to commodities and partner approval. To inform a youth focussed behaviour change communication campaign, Population Services Kenya developed a qualitative study to better understand these barriers among young women. The study was carried out in Nyanza, Coast, and Central regions. Within these regions, urban or peri-urban districts were purposively selected based on having contraceptive prevalence rate close to the regional average and having a population with low socioeconomic profiles. In depth interviews were conducted with a sample of sexually active women aged 15-24, both users and non-users, that were drawn from randomly selected households. All the respondents in the study were familiar with modern methods of contraception and most could describe their general mechanisms of action. Condoms were not considered as contraception by many users. Contraception was also associated with promiscuity and straying. Fear of side effects and adverse reactions were a major barrier to use. The biggest fear was that a particular method would cause infertility. Many fears were based on myths and misconceptions. Young women learn about both true side effects and myths from their social networks. Findings from this research confirm that awareness and knowledge of contraception do not necessarily translate to use. The main barriers to modern contraceptive uptake among young women are myths and misconceptions. The findings stress the influence of social network approval on the use of family planning, beyond the individual's beliefs. In such settings, family planning programming should engage with the wider community through mass and peer campaign strategies. As an outcome from this study, Population Services Kenya developed a mass media campaign to address key myths and

Cellular Immune Response in Young Children Accounts for Recurrent Acute Otitis Media

Sharma, Sharad K.; Pichichero, Michael E.

2013-01-01

Acute otitis media (AOM) is a common disease in young children. Streptococcus pneumoniae(Spn) and Haemophilus influenzae (NTHi) are the two most common pathogens that cause AOM. Over the past 5 years our group has been studying the immunologic profile of children that experience repeated AOM infections despite tympanocentesis drainage of middle ear fluid and individualized antibiotic treatment; we call these children stringently-defined otitis-prone (sOP). Although protection against AOM is primarily mediated by ototpathogen-specific antibody, our recent studies suggest that suboptimal memory B-& T- cell responses and an immaturity in antigen presenting cells may play a significant role in the propensity to recurrent AOM infections. This review focuses on the studies performed to define immunologic dysfunction in sOP children. PMID:24022464

The aim of the present study was to identify anthropometric, physical, coordinative and ice-skating specific characteristics that discriminate young elite ice skaters from non-elite skaters and their non-skating peers. 32 skaters aged 9-12 years old (11 elites and 21 non-elites) voluntarily participated in the study. They were submitted to 5 anthropometric, 7 physical, 3 coordination and 5 ice-skating specific tests. Reference values of a representative healthy non-skating sample were taken from the Flemish Sports Compass dataset. Figure skaters appeared to be predominantly average mature (93.8%), were lighter and leaner than the reference sample, and demonstrated better physical characteristics and motor coordination. There was no difference between the elite and non-elite group regarding maturity status and anthropometric or physical parameters. Still, elite skaters scored better than non-elites on the coordination tests jumping sideways and tended to do so on the moving sideways test. Profiles of figure skaters differ clearly from a reference population, while non-sport-specific motor coordination tests allow discrimination between elite and non-elite skaters. The relevance of these findings with respect to talent detection and identification in young ice skaters are discussed. © Georg Thieme Verlag KG Stuttgart · New York.

Species profiles are literature summaries of the taxonomy, morphology, distribution, life history, and environmental requirements of coastal fishes and invertebrates within a specified range. They are written to assist in environmental impact assessment and decision making by coastal planners and developers. Bluefish are the most important recreational fish in the United States, especially in the mid-Atlantic region. The commercial catch is smaller but has increased during recent years. One population spawns offshore during spring from northern Florida to North Carolina, and these young migrate into mid-Atlantic coastal waters to spend their summer and fall. A second population spawns offshore duringmore » summer from North Carolina to Massachusetts, but most of these young remain offshore for the remainder of the season. In late fall, young and adults of both populations migrate south until the following spring. Bluefish are migratory, opportunistic, pelagic predators throughout life, and their seasonal abundance may have profound community structuring effects. Schools of juvenile bluefish may be important forage for many pelagic predators, including adults of their own species. Photoperiod apparently triggers long-range migration, and temperature serves as a proximal cue to short-range migration. Bluefish are sensitive to bacterial infection in polluted water and have little tolerance for low oxygen conditions. 55 refs., 6 figs., 3 tabs.« less

Many industrialized countries have introduced human papillomavirus (HPV) vaccination of young women, but vaccine uptake often remains suboptimal. This study aimed to investigate whether a social media site like Facebook is an appropriate tool to assess knowledge, attitude and uptake related to HPV vaccination in young women in Germany. Between December 2012 and January 2013 two different targeting strategies were implemented on Facebook, providing a link to an online questionnaire. Advertisements were displayed to female Facebook users aged 18-25 years living in Germany. During the simple targeting strategy, advertisements comprised health-related images along with various short titles and text messages. During the focused strategy, advertisements were targeted to users who in addition had certain fashion brands or pop stars listed on their profiles. The targeting strategies were compared with respect to participant characteristics. Univariate and multivariate analyses were used to identify factors associated with HPV vaccine uptake. A total of 1161 women participated. The two targeting strategies resulted in significant differences regarding educational status and migrant background. Overall, awareness of HPV was high, but only 53% received at least one vaccine dose. In multivariate analysis, HPV vaccine uptake was independently associated with a physician's recommendation and trust in vaccine effectiveness. Concerns of adverse effects were negatively associated with vaccine uptake. Social network recruitment permits fast and convenient access to young people. Sample characteristics can be manipulated by adjusting targeting strategies. There is further need for promoting knowledge of HPV vaccination among young women. Physicians have a major role in the vaccination decision-making process of young women.

Objective We examined postsecondary employment experiences of young adults with an autism spectrum disorder (ASD) and compared these outcomes with those of young adults with different disabilities. Method Data were from Wave 5 of the National Longitudinal Transition Study 2 (NLTS2), a nationally representative survey of young adults who had received special education services during high school. We examined the prevalence of ever having had—and currently having—a paid job at 21–25 years of age. We analyzed rates of full employment, wages earned, number of jobs held since high school, and job types. Results About half (53.4%) of young adults with an ASD had ever worked for pay outside the home since leaving high school, the lowest rate among disability groups. Young adults with an ASD earned an average of $8.10 per hour, significantly lower than average wages for young adults in the comparison groups, and held jobs that clustered within fewer occupational types. Odds of ever having had a paid job were higher for those who were older, from higher-income households, and with better conversational abilities or functional skills. Conclusions Findings of worse employment outcomes for young adults with an ASD suggest this population is experiencing particular difficulty in successfully transitioning into employment. Research is needed to determine strategies for improving outcomes as these young adults transition into adulthood. PMID:23972695

Alignments of two multiple-sequence alignments, or statistical models of such alignments (profiles), have important applications in computational biology. The increased amount of information in a profile versus a single sequence can lead to more accurate alignments and more sensitive homolog detection in database searches. Several profile-profile alignment methods have been proposed and have been shown to improve sensitivity and alignment quality compared with sequence-sequence methods (such as BLAST) and profile-sequence methods (e.g. PSI-BLAST). Here we present a new approach to profile-profile alignment we call Comparison of Alignments by Constructing Hidden Markov Models (HMMs) (COACH). COACH aligns two multiple sequence alignments by constructing a profile HMM from one alignment and aligning the other to that HMM. We compare the alignment accuracy of COACH with two recently published methods: Yona and Levitt's prof_sim and Sadreyev and Grishin's COMPASS. On two sets of reference alignments selected from the FSSP database, we find that COACH is able, on average, to produce alignments giving the best coverage or the fewest errors, depending on the chosen parameter settings.

In 45, ≤ 60 years old patients with CLL and an adverse biologic profile, a front-line treatment with Fludarabine and Campath (Alemtuzumab(®)) was given. The overall response rate was 75.5%, the complete response rate (CR) 24.4% with the lowest CR rates, 16.7% and 8.3%, in 11q and 17p deleted cases. The 3-year progression-free survival (PFS) and overall survival were 42.5% and 79.9%, respectively. PFS was significantly influenced by CLL duration, beta2-microglobulin, and improved by post-remissional stem cell transplantation. Front-line fludarabine and alemtuzumab showed a manageable safety profile and evidence of a benefit in a small series of CLL patients with adverse biologic features. Copyright © 2013 Elsevier Ltd.

Current policy approaches to social and ethical issues surrounding biobanks manifest lack of public information given by researchers and government, despite the evidence that Italian citizens are well informed about technical and other public perspectives of biotechnologies. For this reason, the focus of our survey was to interview our University's students on these aspects. The sample consisted of Padua University students (N = 959), who were administered a questionnaire comprising eight questions covering their knowledge about biobanks, their perception of the related benefits and risks, their willingness to donate samples to a biobank for research purposes, their attitude to having their own DNA profile included in a forensic DNA database, and the reasons behind their answers. The vast majority of the students invited to take part in the survey completed the questionnaire, and the number of participants sufficed to be considered representative of the target population. Despite the respondents' unfamiliarity with the topics explored, suggested by the huge group of respondents answering "I don't know" to the questions regarding Itaian regulation and reality, their answers demonstrate a general agreement to participate in a biobanking scheme for research purposes, as expressed by the 91% of respondents who were reportedly willing to donate their samples. As for the idea of a forensic DNA database, 35% of respondents said they would agree to having their profile included in such a database, even if they were not fully aware of the benefits and risks of such action.This study shows that Italian people with a higher education take a generally positive attitude to the idea of donating biological samples. It contributes to empirical evidence of what Italy's citizens understand about biobanking, and of their willingness to donate samples for research purposes, and also to have their genetic profiles included in a national forensic DNA database.

The main aim of this work was to study the effect of sisal fiber surface treatments on water uptake behavior of composites based on untreated and treated fibers. For this purpose, sisal fibers were treated with different chemical treatments. All surface treatments delayed the water absorption of fibers only for a short time of period. No significant differences were observed in water uptake profiles of composites based on fibers with different surface treatments. After water uptake period, tensile strength and Young modulus values of sisal fiber/poly(lactic acid) (PLA) composites were decreased. On the other hand, composites based on NaOH + silane treated fibers showed the lowest diffusion coefficient values, suggesting that this treatment seemed to be the most effective treatment to reduce water diffusion rate into the composites. Finally, Young modulus values of composites, before water uptake period, were predicted using different micromechanical models and were compared with experimental data. PMID:28773524
