    Myogenic factor mRNA expression was examined during muscle regeneration after bupivacaine injection in Fischer 344/Brown Norway F1 rats aged 3, 18, and 31 mo of age (young, adult, and old, respectively). Mass of the tibialis anterior muscle in the young rats had recovered to control values by 21 days postbupivacaine injection but in adult and old rats remained 40% less than that of contralateral controls at 21 and 28 days of recovery. During muscle regeneration, myogenin mRNA was significantly increased in muscles of young, adult, and old rats 5 days after bupivacaine injection. Subsequently, myogenin mRNA levels in young rat muscle decreased to postinjection control values by day 21 but did not return to control values in 28-day regenerating muscles of adult and old rats. The expression of MyoD mRNA was also increased in muscles at day 5 of regeneration in young, adult, and old rats, decreased to control levels by day 14 in young and adult rats, and remained elevated in the old rats for 28 days. In summary, either a diminished ability to downregulate myogenin and MyoD mRNAs in regenerating muscle occurs in old rat muscles, or the continuing myogenic effort includes elevated expression of these mRNAs.

    The repeated dose liver micronucleus (RDLMN) assay using young adult rats has the potential to detect genotoxic hepatocarcinogens that can be integrated into a general toxicity study. The assay methods were thoroughly validated by 19 Japanese facilities. Methapyrilene hydrochloride (MP), known to be a non-genotoxic hepatocarcinogen, was examined in the present study. MP was dosed orally at 10, 30 and 100mg/kg/day to 6-week-old male Crl:CD (SD) rats daily for 14 days. Treatment with MP resulted in an increase in micronucleated hepatocytes (MNHEPs) with a dosage of only 100mg/kg/day. At this dose level, cytotoxicity followed by regenerative cell growth was noted in the liver. These findings suggest that MP may induce clastogenic effects indirectly on the liver or hepatotoxicity of MP followed by regeneration may cause increase in spontaneous incidence of MNHEPs.

    We have shown that prolonged repetitive reaching and grasping tasks lead to exposure-dependent changes in bone microarchitecture and inflammatory cytokines in young adult rats. Since aging mammals show increased tissue inflammatory cytokines, we sought here to determine if aging, combined with prolonged performance of a repetitive upper extremity task, enhances bone loss. We examined the radius, forearm flexor muscles, and serum from 16 mature (14-18months of age) and 14 young adult (2.5-6.5months of age) female rats after performance of a high repetition low force (HRLF) reaching and grasping task for 12weeks. Young adult HRLF rats showed enhanced radial bone growth (e.g., increased trabecular bone volume, osteoblast numbers, bone formation rate, and mid-diaphyseal periosteal perimeter), compared to age-matched controls. Mature HRLF rats showed several indices of radial bone loss (e.g., decreased trabecular bone volume, and increased cortical bone thinning, porosity, resorptive spaces and woven bone formation), increased osteoclast numbers and inflammatory cytokines, compared to age-matched controls and young adult HRLF rats. Mature rats weighed more yet had lower maximum reflexive grip strength, than young adult rats, although each age group was able to pull at the required reach rate (4reaches/min) and required submaximal pulling force (30force-grams) for a food reward. Serum estrogen levels and flexor digitorum muscle size were similar in each age group. Thus, mature rats had increased bone degradative changes than in young adult rats performing the same repetitive task for 12weeks, with increased inflammatory cytokine responses and osteoclast activity as possible causes.

    Prenatal ethanol exposure (PNEE) causes significant deficits in functional (i.e., synaptic) plasticity in the dentate gyrus (DG) and cornu ammonis (CA) hippocampal sub-regions of young adult male rats. Previous research has shown that in the DG, these deficits are not apparent in age-matched PNEE females. This study aimed to expand these findings and determine if PNEE induces deficits in hippocampal-dependent behaviours in both male and female young adult rats (PND 60). The metric change behavioural test examines DG-dependent deficits by determining whether an animal can detect a metric change between two identical objects. The temporal order behavioural test is thought to rely in part on the CA sub-region of the hippocampus and determines whether an animal will spend more time exploring an object that it has not seen for a larger temporal window as compared to an object that it has seen more recently. Using the liquid diet model of FASD (where 6.6% (v/v) ethanol is provided through a liquid diet consumed ad libitum throughout the entire gestation), we found that PNEE causes a significant impairment in the temporal order task, while no deficits in the DG-dependent metric change task were observed. There were no significant differences between males and females for either task. These results indicate that behaviours relying partially on the CA-region may be more affected by PNEE than those that rely on the DG. PMID:26632335

  6. Study of non-opioid analgesics tolerance in young and adult rats.

    It was demonstrated that systemic injections of metamizol and lysine-acetylsalicylate (LASA) induce inhibition of tail-flick reflex and hot-plate responses and their repeated administration leads to the development of tolerance. However, it has not been established whether these effects can be elicited by other non-steroidal anti-inflammatory drugs (NSAIDs). In this study the authors used other commonly applied analgesics--analgine, ketorolac, xefocam, which are the representatives of the three diverse groups of NSAIDs. In particular, analgine is a derivative of pirozolon, while ketorolac belongs to indoles and xefocam to amoxicams. The authors decided to examine and compare tolerance to analgine, ketorolac and xefocam in groups of young and adult rats. The experiments were carried out on experimental and control rats with saline by the model of tail-flick reflex to the stimulation of focusing light. Latency increase of this reflex indicates the degree of antinociception. The present study has revealed that systemic, intraperitoneal injections of NSAIDs (analgine, ketorolac and xefocam), the equivalent to maximal analgesic doses for humans, induces antinociception in awake rats of young and adult ages and when administered repeatedly, induce tolerance to these drugs and cross-tolerance to morphine. This is in line with results of earlier experiments, in which metamizol or LASA were given intravenously or microinjected into the periaqueductal gray matter. More importantly, the study indicate that the repeated administration of these non-opioid analgesics induces a decrease in antinociceptive effectiveness reminiscent of that induced by opiates. Moreover, the present results paradoxically suggest that analgine, ketorolac and xefocam tolerance is related to the endogenous opioid system. Taken together the present and previous findings the authors support the notion that the contribution of the CNS, particularly of the downstream pain-control system, to the tolerance effects of NSAIDs involve endogenous opioidergic mechanisms.

    Thyroid hormones and oxidative stress play significant roles in the normal functioning of the female reproductive system. Nitric oxide (NO), a free radical synthesized by nitric oxide synthases (NOS), participates in the regulation of thyroid function and is also a good biomarker for assessment of the oxidative stress status. Therefore, the purpose of this study was to investigate effects of thyroid hormones on uterine antioxidative status in young adult rats. Thirty immature female Sprague-Dawley rats were randomly divided into three groups: control, hypothyroid (hypo-T) and hyperthyroid (hyper-T). The results showed the body weights decreased significantly in both the hypo-T and hyper-T groups and that uterine weights were decreased significantly in the hypo-T group. The serum concentrations of total triiodothyronine (T3) and thyroxine (T4), as well as estradiol (E2), were significantly decreased in the hypo-T group, but increased in the hyper-T group. The progesterone (P4) concentrations in the hypo- and hyperthyroid rats markedly decreased. Immunohistochemistry results provided evidence that thyroid hormone nuclear receptor ?/? (TR?/?) and three NOS isoforms were located in different cell types of rat uteri. The NO content and total NOS and inducible NOS (iNOS) activities were markedly diminished in the hypo-T group but increased in the hyper-T group. Moreover, the activities of both glutathione peroxidase (GSH-Px) and catalase (CAT) exhibited significant decreases and increases in the hypo-T and hyper-T groups, respectively. The malondialdehyde (MDA) contents in both the hypo-T and hyper-T groups showed a significant increase. Total superoxide dismutase (T-SOD) activity in the hypo- and hyper-T rats markedly decreased. In conclusion, these results indicated that thyroid hormones have an important influence on the modulation of uterine antioxidative status. PMID:25797533

    In this study, the effects of pentavalent dimethylarsinic acid ((CH{sub 3}){sub 2}AsO(OH); DMA{sup V}) and trivalent dimethylarsinous acid ((CH{sub 3}){sub 2}As(OH); DMA{sup III}) on synaptic transmission generated by the excitatory Schaffer collateral-CA1 synapse were tested in hippocampal slices of young (14-21 day-old) and adult (2-4 month-old) rats. Both compounds were applied in concentrations of 1 to 100 {mu}mol/l. DMA{sup V} had no effect on the amplitudes of evoked fEPSPs or the induction of LTP recorded from the CA1 dendritic region either in adult or in young rats. However, application of DMA{sup III} significantly reduced the amplitudes of evoked fEPSPs in a concentration-dependent manner with a total depression following application of 100 {mu}mol/l DMA{sup III} in adult and 10 {mu}mol/l DMA{sup III} in young rats. Moreover, DMA{sup III} significantly affected the LTP-induction. Application of 10 {mu}mol/l DMA{sup III} resulted in a complete failure of the postsynaptic potentiation of the fEPSP amplitudes in slices taken both from adult and young rats. The depressant effect was not reversible after a 30-min washout of the DMA{sup III}. In slices of young rats, the depressant effects of DMA{sup III} were more pronounced than in those taken from adult ones. Compared to the (absent) effect of DMA{sup V} on synaptic transmission, the trivalent compound possesses a considerably higher neurotoxic potential.

  9. Ion transport in the heart atrial tissue of young and adult guinea-pigs and albino rats.

    Rubidium shifts between the extracellular fluid and cells were studied in the isolated atria of guinea-pig and albino rat hearts. In the young of both species, rubidium transport from the incubation medium to the cells was much slower than in preparations from adult animals. That implies that the efficiency of membrane mechanisms for the transport of Na+ and K+ ions in the atrial tissue increases during postnatal life. This conclusion is further confirmed by the finding that the intracellular potassium concentration in the atrial tissue of the young of both species is lower, and the intracellular sodium concentration higher, than in adult animals. Conversely, the serum potassium concentration in the young is higher, and the serum sodium concentration lower, than in adult individuals. PMID:157489

    Arsenite and its metabolites, dimethylarsinic or dimethylarsinous acid, have previously been shown to disturb synaptic transmission in hippocampal slices of rats (Krueger, K., Gruner, J., Madeja, M., Hartmann, L.M., Hirner, A.V., Binding, N., Mu{beta}hoff, U., 2006a.

Effects of dimethylarsinic and dimethylarsinous acid on evoked synaptic potentials in hippocampal slices of young and adult rats. Toxicol. Appl. Pharmacol. 225, 40-46). The present experiments investigate, whether the important arsenic metabolites monomethylarsonic acid (MMA{sup V}) and monomethylarsonous acid (MMA{sup III}) also influence the synaptic functions of the hippocampus. In hippocampal slices of young (14-21 days-old) and adult (2-4 months-old) rats, evoked synaptic field potentials from the Schaffer collateral-CA1 synapse were measured under control conditions and during and after 30 and 60 min of application of the arsenic compounds. MMA{sup V} had no effect on the synapse functions neither in slices of adult nor in those from young rats. However, MMA{sup III} strongly influenced the synaptic transmission: it totally depressed the amplitudes of fEPSPs at concentrations of 50 {mu}mol/l (adult rats) and 25 {mu}mol/l (young rats) and LTP amplitudes at concentrations of 25 {mu}mol/l (adult rats) and 10 {mu}mol/l (young rats), respectively. In contrast, application of 1 {mu}mol/l MMA{sup III} led to an enhancement of the LTP amplitude in young rats, which is interpretable by an enhancing effect on NMDA receptors and a lack of the blocking effect on AMPA receptors at this concentration (Krueger, K., Gruner, J., Madeja, M., Hartmann, L.M., Hirner, A.V., Binding, N., Mu{beta}hoff, U., 2006a. Blockade and enhancement of glutamate receptor responses in Xenopus oocytes by methylated arsenicals. Arch. Toxicol. 80, 492-501). These effects are probably not mediated by changes in cell excitability or in presynaptic glutamate release rates, since antidromically induced population spikes and paired-pulse facilitation failed to show any MMA{sup III} effect. The impairment of the excitatory CA1 synapse is more likely caused by the action of MMA{sup III} on postsynaptic glutamatergic receptors and may be jointly responsible for dysfunctions of cognitive effects in arsenic toxicity.

    The repeated-dose liver micronucleus (MN) assay is a newly established in vivo genotoxicity test for evaluation of liver carcinogens. It may be integrated into general toxicity studies, thereby reducing the numbers of animals required for assessment of chemical safety. A collaborative study by the Mammalian Mutagenicity Study (MMS) Group further evaluated this assay using a wide range of chemicals, including carcinogens and non-carcinogens in young adult rats. In this study, we administered clofibrate (125, 250, or 500mg/kg/day) for 14 or 28 days, and examined the micronucleated (MNed) cell frequencies in the liver and bone marrow. Clofibrate is a known liver carcinogen specific to rodents and has been shown to yield negative results in many in vitro genotoxicity and carcinogenicity tests in monkeys. Clofibrate is categorized as a Group 3 chemical by the International Agency for Research on Cancer and is considered a non-genotoxic carcinogen. After treatment with clofibrate for 14 or 28 days, frequencies of hepatic MNed cells were significantly increased, but there were no differences in the ratios of hepatic M-phase cells. Clofibrate did not increase the frequency of MNed cells in the bone marrow in the 14-day study, whereas a slight increase was observed at the highest dose in the 28-day study. These results suggested that the repeated-dose liver MN assay is more sensitive to clofibrate, an indirect liver carcinogen in rodents, than the conventional bone marrow MN assay. PMID:25892631

    We examined the effect of 28 days of overload on mammalian target of rapamycin (mTOR) and extracellular signal-regulated kinase (ERK) signaling in young adult (Y; 6-month old) and aged (O; 30-month old) Fischer 344 x Brown Norway rats subjected to bilateral synergist ablation (SA) of two thirds of the gastrocnemius muscle or sham surgery (CON). Although plantaris (PLA) muscle hypertrophy was attenuated by aging, mTOR phosphorylation was 44% and 35% greater in Y SA and O SA compared with CON (p = .038). Ribosomal protein S6 phosphorylation was 114% and 24% higher in Y SA and O SA compared with CON (p = .009). Eukaryotic initiation factor 2Bepsilon phosphorylation was 33% and 9% higher in Y SA and O SA compared with CON (p = .04). Translational signaling in young adult and aged plantaris muscle is equally responsive to chronic overload. PMID:19808838

    Treosulfan (TREO) is currently investigated as an alternative treatment of busulfan in conditioning before hematopoietic stem cell transplantation. The knowledge of the blood-brain barrier penetration of the drug is still scarce. In this paper, penetration of TREO and its active monoepoxide (S,S-EBDM) and diepoxide (S,S-DEB) into the CNS was studied in juvenile (JR) and young adult rats (YAR) for the first time. CD rats of both sexes (n = 96) received an intravenous dose of TREO 500 mg/kg b.wt. Concentrations of TREO, S,S-EBDM, and S,S-DEB in rat plasma, brain, and cerebrospinal fluid (CSF, in YAR only) were determined by validated bioanalytical methods. Pharmacokinetic calculations were performed in WinNonlin using a noncompartmental analysis and statistical evaluation was done in Statistica software. In male JR, female JR, male YAR, and female YAR, the brain/plasma area under the curve (AUC) ratio for unbound TREO was 0.14, 0.17, 0.10, and 0.07 and for unbound S,S-EBDM, it was 0.52, 0.48, 0.28, and 0.22, respectively. The CSF/plasma AUC ratio in male and female YAR was 0.12 and 0.11 for TREO and 0.66 and 0.64 for S,S-EBDM, respectively. Elimination rate constants of TREO and S,S-EBDM in all the matrices were sex-independent with a tendency to be lower in the JR. No quantifiable levels of S,S-DEB were found in the studied samples. TREO and S,S-EBDM demonstrated poor and sex-independent penetration into CNS. However, the brain exposure was greater in juvenile rats, so very young children might potentially be more susceptible to high-dose TREO-related CNS exposure than young adults. PMID:26428246

    The antidepressant effect of estrogens combined with antidepressants is controversial: some preclinical data showed that estrogens facilitate the effect of antidepressants in the forced swimming test (FST) in young adult rats, while others failed to find such effect in middle-aged rats in the chronic mild stress (CMS) model. In clinics similar differences were reported and may be due to the compounds, the depression model or type of depression, the experimental design, and the age of the subjects or the women's menopause stage. The objective of this study was to analyze the antidepressant-like effect of the combination of 17?-estradiol (E(2)) and fluoxetine (FLX) in young adults (2-4 months) and middle-aged (12-14 months) ovariectomized (OVX) rats in two experimental models: FST and CMS. E(2) (5 and 10 ?g/rat) and FLX (2.5 and 10 mg/kg) per se dose-dependently reduced immobility in both age groups and, in young adults both compounds increased swimming, whereas in middle-aged rats they increased swimming and climbing. Analysis of the antidepressant-like effect of the combination of suboptimal doses of FLX (1.25 mg/kg) and E(2) (2.5 ?g/rat) showed a decrease in immobility and an increase in swimming in both age groups. In the CMS, chronic E(2) (2.5 ?g/rat) with FLX (1.25 mg/kg) augmented relative sucrose intake, but middle-aged rats responded 2 weeks earlier than young adults. These results show that the antidepressant-like effect of the combination of E(2) and FLX in young adult and middle-aged female rats is evidenced in the two animal models of depression: FST and CMS.

    N-Methyl-N'-nitro-N-nitrosoguanidine (MNNG) is a direct-acting mutagen that induces tumors in the glandular stomach, but not in the liver or colon, of rats after oral administration. To evaluate the performance of repeated dose liver and gastrointestinal tract micronucleus (MN) assays in young adult rats, MNNG was administered by oral gavage to male CD (SD) rats aged 6 weeks at doses of 0 (vehicle; 2.5% DMSO aqueous solution), 3.125, 6.25, 12.5, and 25mg/kg/day once daily for 14 and 28 days, and the MN frequencies were examined in the hepatocytes, glandular stomach cells, and colonic cells. The MN induction in immature erythrocytes in the bone marrow of these animals was also simultaneously evaluated. The frequencies of micronucleated (MNed) glandular stomach cells were significantly increased in all MNNG treatment groups in a dose-dependent manner in both repeated dose studies. In contrast, the frequencies of MNed hepatocytes and colonic cells were not significantly increased compared to the vehicle control. In the bone marrow, a small but significant increase in the frequency of MNed immature erythrocytes was observed only at the highest dose in the 28-day study. Since a clear positive result in the glandular stomach agrees with the tissue specificity of tumor induction by this chemical, the MN assay with the glandular stomach, which is a direct contact site with high concentrations of test substances administered by oral gavage, may be useful for detecting genotoxic compounds that are short-lived in vivo, such as MNNG.

    This study investigated the effect of exposure to mobile phone radiations on oxidative stress and apoptosis in brain of rats. Rats were allocated into six groups (three young and three adult). Groups 1 and 4 were not subjected to the radiation source and served as control groups. In groups 2 and 5, the mobile phones were only connected to the global system for mobile communication, while in groups 3 and 6, the option of calling was in use. Microwaves were generated by a mobile test phone (SAR = 1.13 W/kg) during 60 days (2 h/day). Significant increments in conjugated dienes, protein carbonyls, total oxidant status, and oxidative stress index along with a significant reduction of total antioxidant capacity levels were evident after exposure. Bax/Bcl-2 ratio, caspase-3 activity, and tumor necrosis factor-alpha level were enhanced, whereas no DNA fragmentation was detected. The relative brain weight of young rats was greatly affected, and histopathological examination reinforced the neuronal damage. The study highlights the detrimental effects of mobile phone radiations on brain during young and adult ages. The interaction of these radiations with brain is via dissipating its antioxidant status and/or triggering apoptotic cell death. PMID:24801773

    Purpose Sexting has stirred debate over its legality and safety, but few researchers have documented the relationship between sexting and health. We describe the sexting behavior of young adults in the United States, and examine its association with sexual behavior and psychological well-being. Methods Using an adapted web version of Respondent-Driven Sampling (webRDS) we recruited a sample of U.S. young adults (ages 18 to 24; N=3447). We examined participant sexting behavior using 4 categories of sexting: 1) Non-Sexters, 2) Receivers, 3) Senders, and 4) Two-way Sexters. We then assessed the relationships between sexting categories and sociodemographic characteristics, sexual behavior and psychological well-being. Results Over half (57%) of respondents were Non-Sexters, 28.2% of the sample were Two-way Sexters, 12.6% were Receivers, and 2% were Senders. Males were more likely to be Receivers than females. Sexually active respondents were more likely to be Two-way Sexters than non-sexually active respondents. Among participants who were sexually active in the past 30 days, we found no differences across sexting groups in number of sexual partners, or number of unprotected sex partners in the past 30 days. We also found no relationship between sexting and psychological well-being. Conclusions Our results suggest that sexting is not related to sexual risk behavior or psychological well-being. We discuss the findings of this study and propose directions for further research on sexting. PMID:23299018

    Smoking during pregnancy exposes the fetus to nicotine, resulting in nicotine-stimulated neurotransmitter release. Recent evidence suggests that the hippocampus develops differently in males and females with delayed maturation in males. We show that chronic nicotine exposure during the first postnatal week has sex-specific long-term effects. Neonatal rat pups were chronically treated with nicotine (6mg/kg/day) (CNN) from postnatal day 1 to 7 or milk only (Controls), and hippocampal slices were prepared from Control- and CNN-treated young adults. Field excitatory postsynaptic potentials (fEPSPs) or population spikes (PSs) were recorded from the CA1 hippocampus following CA1 s. radiatum stimulation. Input/Output curves constructed from fEPSP data indicated that CNN-males, but not females, had significantly increased excitatory responses compared to Controls (p<0.05, n=10 Con, n=11 CNN). Long-term potentiation (LTP) was not significantly changed by CNN. In the presence of bicuculline, which blocks inhibitory GABA(A) receptors, an epileptiform burst consisting of a series of PSs was evoked. The amplitude of the first PS was significantly larger in CNN-males and females compared to Controls (males: p<0.01, n=8 Con, n=8 CNN; females: p<0.05, n=9 Con, n=7 CNN). Only CNN-males also had significantly larger second PSs (p<0.05, n=8 con, n=8 CNN). Epileptiform activity evoked by zero Mg(2+) incubation did not differ in amplitude or duration of bursts in CNN-males or females compared to Controls. These data indicate that neonatal nicotine exposure has long lasting effects and results in increased excitation within the CA1 hippocampus in adulthood, with males showing increased sensitivity to nicotine's effects.

    Behavior, in its broadest definition, can be defined as the motor manifestation of physiologic processes. As such, all behaviors manifest through the motor system. In the fields of neuroscience and orthopedics, locomotion is a commonly evaluated behavior for a variety of disease models. For example, locomotor recovery after traumatic injury to the nervous system is one of the most commonly evaluated behaviors 1-3. Though locomotion can be evaluated using a variety of endpoint measurements (e.g. time taken to complete a locomotor task, etc), semiquantitative kinematic measures (e.g. ordinal rating scales (e.g. Basso Beattie and Bresnahan locomotor (BBB) rating scale, etc)) and surrogate measures of behaviour (e.g. muscle force, nerve conduction velocity, etc), only kinetics (force measurements) and kinematics (measurements of body segments in space) provide a detailed description of the strategy by which an animal is able to locomote 1. Though not new, kinematic and kinetic measurements of locomoting rodents is now more readily accessible due to the availability of commercially available equipment designed for this purpose. Importantly, however, experimenters need to be very familiar with theory of biomechanical analyses and understand the benefits and limitations of these forms of analyses prior to embarking on what will become a relatively labor-intensive study. The present paper aims to describe a method for collecting kinematic and ground reaction force data using commercially available equipment. Details of equipment and apparatus set-up, pre-training of animals, inclusion and exclusion criteria of acceptable runs, and methods for collecting the data are described. We illustrate the utility of this behavioral analysis technique by describing the kinematics and kinetics of strain-matched young adult, middle-aged, and geriatric rats. PMID:21403621

    Calcium binding proteins play important roles in all aspects of neural functioning in the central nervous system. In the present study, we examined age-related changes of three different calcium binding proteins calbindin-D28k (CB), calretinin (CR) and parvalbumin (PV) immunoreactivities in the striatum of young (1 month), adult (6 months) and aged (24 months) ages in three species of rodents (mouse, rat and gerbil) using immunohistochemistry and Western blotting. Our results show that the number of CB-immunoreactive neurons was highest in the adult mouse and rat; however, in the gerbil, the number of CB-immunoreactive neurons was not significantly different from each group although the CB immunoreactivity was significantly decreased in the aged group compared with the adult group. The number of CR-immunoreactive neurons in the striatum was significantly highest in all the adult groups, and, especially, the number of CR-immunoreactive neurons and CR immunoreactivity in the aged gerbil were significantly decreased in the aged group compared with the other groups. Finally, we did not found any significant difference in the number of PV-immunoreactive neurons in the striatum with age among the three rodents. On the other hand, we found that protein levels of three calcium binding proteins in all the mouse groups were similar to the immunohistochemical data. These results indicate that the distribution pattern of calcium binding proteins is different according to age; the adult might show an apparent tendency of high expression in the striatum.

    2014-01-01

    Background Dietary fibre-induced satiety offers a physiological approach to body weight regulation, yet there is lack of scientific evidence. This experiment quantified food intake, body weight and body composition responses to three different soluble fermentable dietary fibres in an animal model and explored underlying mechanisms of satiety signalling and hindgut fermentation. Methods Young adult male rats were fed ad libitum purified control diet (CONT) containing 5% w/w cellulose (insoluble fibre), or diet containing 10% w/w cellulose (CELL), fructo-oligosaccharide (FOS), oat beta-glucan (GLUC) or apple pectin (PECT) (4 weeks; n = 10/group). Food intake, body weight, and body composition (MRI) were recorded, final blood samples analysed for gut satiety hormones, hindgut contents for fermentation products (including short-chain fatty acids, SCFA) and intestinal tissues for SCFA receptor gene expression. Results GLUC, FOS and PECT groups had, respectively, 10% (P < 0.05), 17% (P < 0.001) and 19% (P < 0.001) lower food intake and 37% (P < 0.01), 37% (P < 0.01) and 45% (P < 0.001) lower body weight gain than CONT during the four-week experiment. At the end they had 26% (P < 0.05), 35% (P < 0.01) and 42% (P < 0.001) less total body fat, respectively, while plasma total glucagon-like peptide-1 (GLP-1) was 2.2-, 3.2- and 2.6-fold higher (P < 0.001) and peptide tyrosine tyrosine (PYY) was 2.3-, 3.1- and 3.0-fold higher (P < 0.001). There were no differences in these parameters between CONT and CELL. Compared with CONT and CELL, caecal concentrations of fermentation products increased 1.4- to 2.2-fold in GLUC, FOS and PECT (P < 0.05) and colonic concentrations increased 1.9- to 2.5-fold in GLUC and FOS (P < 0.05), with no consistent changes in SCFA receptor gene expression detected. Conclusions This provides animal model evidence that sustained intake of three different soluble dietary fibres decreases food intake, weight gain and adiposity, increases circulating satiety hormones GLP-1 and PYY, and increases hindgut fermentation. The presence of soluble fermentable fibre appears to be more important than its source. The results suggest that dietary fibre-induced satiety is worthy of further investigation towards natural body weight regulation in humans. PMID:25152765

    Toluene, an industrial organic solvent, is voluntarily inhaled as drug of abuse. Toluene has been shown to inhibit the nicotinic acetylcholine receptors. Nicotinic receptors play an important role in brain development during brain growth spurt and early adolescence. The long-term effects of neonatal and adolescent toluene exposure on behavioral responses to nicotine in early adulthood were compared. Sprague-Dawley male and female rats were treated with toluene (500 mg/kg, ip) or corn oil daily over postnatal day (PN) 4-9 or 25-30. Nicotine-induced hypothermia, antinociception, and seizure activity were examined during PN 56-60. Toluene exposure during the brain growth spurt, but not adolescence, reduced the behavioral responses to nicotine in young adult rats. However, the levels of alpha4, alpha7, and beta2 nicotinic receptors were not altered in the frontal cortex, striatum, thalamus, hippocampus, and cerebellum by neonatal toluene exposure. These results indicate that toluene exposure during the brain growth spurt produces long-term changes in nicotine sensitivity, which may be unrelated to the total expression levels of alpha4, alpha7, and beta2 nicotinic receptors. The alterations in nicotine sensitivity may be related to the neurobehavioral disturbance associated with fetal solvent syndrome. PMID:17951610

    The influence of aging on susceptibility to environmental contaminants is not well understood. To extend knowledge in this area, we examined effects in rat brain of the volatile organic compound, toluene. The objective was to test whether oxidative stress (OS) plays a role in the adverse effects caused by toluene exposure, and if so, if effects are age-dependent. OS parameters were selected to measure the production of reactive oxygen species (NADPH Quinone oxidoreductase 1 (NQO1), NADH Ubiquinone reductase (UBIQ-RD)), antioxidant homeostasis (total antioxidant substances (TAS), superoxide dismutase (SOD), ?-glutamylcysteine synthetase (?-GCS), glutathione transferase (GST), glutathione peroxidase (GPX), glutathione reductase (GRD)), and oxidative damage (total aconitase and protein carbonyls). In this study, Brown Norway rats (4, 12, and 24 months) were dosed orally with toluene (0, 0.65 or 1g/kg) in corn oil. Four hours later, frontal cortex, cerebellum, striatum, and hippocampus were dissected, quick frozen on dry ice, and stored at -80°C until analysis. Some parameters of OS were found to increase with age in select brain regions. Toluene exposure also resulted in increased OS in select brain regions. For example, an increase in NQO1 activity was seen in frontal cortex and cerebellum of 4 and 12 month old rats following toluene exposure, but only in the hippocampus of 24 month old rats. Similarly, age and toluene effects on glutathione enzymes were varied and brain-region specific. Markers of oxidative damage reflected changes in oxidative stress. Total aconitase activity was increased by toluene in frontal cortex and cerebellum at 12 and 24 months, respectively. Protein carbonyls in both brain regions and in all age groups were increased by toluene, but step-down analyses indicated toluene effects were statistically significant only in 12month old rats. These results indicate changes in OS parameters with age and toluene exposure resulted in oxidative damage in frontal cortex and cerebellum of 12 month old rats. Although increases in oxidative damage are associated with increases in horizontal motor activity in older rats, further research is warranted to determine if these changes in OS parameters are related to neurobehavioral and neurophysiological effects of toluene in animal models of aging.

    Strokes in young adults are reported as being uncommon, comprising 10%–15% of all stroke patients. However, compared with stroke in older adults, stroke in the young has a disproportionately large economic impact by leaving victims disabled before their most productive years. Recent publications report an increased incidence of stroke in young adults. This is important given the fact that younger stroke patients have a clearly increased risk of death compared with the general population. The prevalence of standard modifiable vascular risk factors in young stroke patients is different from that in older patients. Modifiable risk factors for stroke, such as dyslipidemia, smoking, and hypertension, are highly prevalent in the young stroke population, with no significant difference in geographic, climatic, nutritional, lifestyle, or genetic diversity. The list of potential stroke etiologies among young adults is extensive. Strokes of undetermined and of other determined etiology are the most common types among young patients according to TOAST (Trial of Org 10172 in Acute Stroke Treatment) criteria. Prevention is the primary treatment strategy aimed at reducing morbidity and mortality related to stroke. Therefore, primary prevention is very important with regard to stroke in young adults, and aggressive treatment of risk factors for stroke, such as hypertension, smoking, and dyslipidemia, is essential. The best form of secondary stroke prevention is directed toward stroke etiology as well as treatment of additional risk factors. However, there is a lack of specific recommendations and guidelines for stroke management in young adults. In conclusion, strokes in young adults are a major public health problem and further research, with standardized methodology, is needed in order to give us more precise epidemiologic data. Given the increasing incidence of stroke in the young, there is an objective need for more research in order to reduce this burden. PMID:25750539

    Antiaging therapies show promise in model organism research. Translation to humans is needed to address the challenges of an aging global population. Interventions to slow human aging will need to be applied to still-young individuals. However, most human aging research examines older adults, many with chronic disease. As a result, little is known about aging in young humans. We studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. We developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. Our longitudinal measure allows quantification of the pace of coordinated physiological deterioration across multiple organ systems (e.g., pulmonary, periodontal, cardiovascular, renal, hepatic, and immune function). We applied these methods to assess biological aging in young humans who had not yet developed age-related diseases. Young individuals of the same chronological age varied in their "biological aging" (declining integrity of multiple organ systems). Already, before midlife, individuals who were aging more rapidly were less physically able, showed cognitive decline and brain aging, self-reported worse health, and looked older. Measured biological aging in young adults can be used to identify causes of aging and evaluate rejuvenation therapies. PMID:26150497

    1998-12-01

    After graduating from college and entering the work force, young adult athletes often struggle with the task of fueling themselves optimally for top performance and weight control. The stresses and time constraints of work, family, and social responsibilities often result in eating fast foods on the run. These young adults can benefit from nutrition education programs in the worksite, at health clubs, in the community, and via the media. Dietitians who specialize in sport nutrition have particular appeal to these athletes, who are struggling to each well, exercise well, and stay lean yet put little time or effort into their food program. This article includes two case studies of young adults and the dietary recommendations that taught them how to make wise food choices, fuel themselves well for high energy, and control their weight.

  1. [Ischemic stroke in the young adult].

    PubMed

    Calvet, D

    2016-01-01

    Ischemic stroke is not rare in young adults since one in ten stroke patients are less than 50years old. This incidence increased over the past last years, mainly due to the rise in the prevalence of traditional vascular risk factors in this sub-group of age but also of illegal drug use. Even though both survival and functional outcome of young stroke patients are better than those observed in older patients, socio-economic and quality of life consequences make this disease a main objective in terms of primary and secondary prevention. Identifying the cause of ischemic stroke in young adults is of major importance to prevent stroke recurrence. However, given the wide variety of potential underlying causes, the etiologic work-up of stroke in young adults requires a different approach from that in the elderly. In this context, a sequential diagnostic work-up is needed in order to optimize the yield of diagnostic tests, to reduce their cost and risks for the patient. Arterial dissection is the most frequent cause of stroke in young adults but other less frequent causes are numerous. Despite a comprehensive work-up, about one third of cases remains unexplained leading to the diagnosis of cryptogenic ischemic stroke. PMID:26361979

  1. Specific characteristics of sympathetic fibres innervating the heart of young rats.

    PubMed

    Vlk, J; Volín, M

    1980-01-01

    The noradrenaline content of the heart of albino rats was determined spectrofluorometrically by the trihydroxyindole method after adsorption to aluminium oxide. The concentration (mg/kg tissue) changed during postnatal life as follows: at 10 and 18 days--0.13, 24 days--0.18, 35 days--0.21, 45 days--0.34, over 3 months--0.68. We determined whether the low transmitter concentration in the heart tissue of the young was reflected in the function of the sympathetic fibres innervating and sinoatrial node. We stimulated the region of the sinoatrial node electrically in isolated atria and compared the positive chronotropic reaction of preparations from 15-day-old young and adult rats to various forms of stimulation (bursts of 1-5 s, frequencies of 10-100 Hz, voltage 10-25 V, duration of individual pulses 0.02-0.08 ms). The reactions of young and adult rats were all identical except for two: 1. with the shortest pulses (0.02 ms), the sympathetic innervation of the young hardly reacted at all, while adult animals had a marked positive chronotropic reaction; 2. with 5-s bursts, young rats reacted significantly more strongly than adult animals. The first of these differences could be related to lower excitability of infant rat nerve fibres, while insufficient reuptake of noradrenaline in the heart of infant rats could have accounted for the second.

  11. Low-dose memantine-induced working memory improvement in the allothetic place avoidance alternation task (APAAT) in young adult male rats

    PubMed Central

    Wesierska, Malgorzata J.; Duda, Weronika; Dockery, Colleen A.

    2013-01-01

    N-methyl-D-aspartate receptors (NMDAR) are involved in neuronal plasticity. To assess their role simultaneously in spatial working memory and non-cognitive learning, we used NMDAR antagonists and the Allothetic Place Avoidance Alternation Task (APAAT). In this test rats should avoid entering a place where shocks were presented on a rotating arena which requires cognitive coordination for the segregation of stimuli. The experiment took place 30 min after intraperitoneal injection of memantine (5, 10, 20 mg/kg b.w.: MemL, MemM, MemH, respectively) and (+)MK-801 (0.1, 0.2, 0.3 mg/kg b.w.: MK-801L, MK-801M, MK-801H, respectively). Rats from the control group were intact or injected with saline (0.2 ml/kg). Over three consecutive days the rats underwent habituation, two avoidance training intervals with shocks, and a retrieval test. The shock sector was alternated daily. The after-effects of the agents were tested on Day 21. Rats treated with low dose memantine presented a longer maximum time avoided and fewer entrances than the MemH, MK-801M, MK-801H and Control rats. The shocks per entrances ratio, used as an index of cognitive skill learning, showed skill improvement after D1, except for rats treated by high doses of the agents. The activity levels, indicated by the distance walked, were higher for the groups treated with high doses of the agents. On D21 the MK801H rats performed the memory task better than the MemH rats, whereas the rats' activity depended on condition, not on the group factor. These results suggest that in naïve rats mild NMDAR blockade by low-dose memantine improves working memory related to a highly challenging task. PMID:24385956

  12. Nonmedical use of prescription medications in young adults.

    PubMed

    Tapscott, Brian E; Schepis, Ty S

    2013-12-01

    Nonmedical use of prescription medications (NUPM) is an area of increasing public health concern, particularly in young adults. Young adults aged 18 to 25 have the highest annual and monthly rates of NUPM of any age group in the US, with notable consequences from using opioid, stimulant, tranquilizer and sedative medication. This article will review the literature on young adult NUPM, focusing first on the characteristics of those young adults engaged in NUPM. Then, we will examine the most common motives for NUPM, the sources young adults use to engage in nonmedical use and the related process of medication diversion. Finally, we will outline treatment and make specific recommendations of ways clinicians can help prevent the spread of NUPM in young adults, completing the work by covering future directions for research.

    2014-01-01

    Sexual prejudice is linked to hate crimes, mental health, risk behaviors, and stigma. Few studies have examined sexual prejudice among Latinos. We surveyed 382 college students in Puerto Rico. A structural model tested whether contact and positive experiences with homosexuals, perceived similarities with peers' attitudes toward homosexuality, and religiosity were predictive of sexual prejudice among Puerto Rican young adults. Sex differences in the structural model were explored. With the exception of peers' attitudes toward homosexuality, all study variables predict sexual prejudice. No sex differences were found. Implications for decreasing sexual prejudice among Puerto Rican youth in a college setting are discussed. PMID:18689195

    2012-01-01

    Past research has linked both emotion regulation and impulsivity with the development and maintenance of addictions. However, no research has investigated the relationship between emotion regulation and impulsivity within young adults. In the present study, we analyzed 194 young adults (27.8% female; 21.3 ± 3.32 years old; 91.8% single; 85.1% Caucasian), grouping them as low, average, or high emotionally dysregulated, and compared self-reported impulsivity, impulsive behaviors (such as alcohol and substance use and gambling) and cognitive impulsivity. We hypothesized that those with high levels of emotion dysregulation would score higher on self-reported and cognitive impulsivity, and report more impulsive behaviors. Analysis indicated that compared to low, the high emotion dysregulation group scored significantly higher on two self-report measures of impulsivity, harm avoidance, and cognitive reasoning. No significant differences were found between groups in impulsive behaviors and cognitive impulsivity. Overall, this study highlights the relationship between emotion dysregulation and impulsivity, suggesting that emotion regulation may be an important factor to consider when assessing individuals at a higher risk for developing an addiction.

    Background Stroke may be a clinical expression of several inherited disorders in humans. Recognition of the underlined genetic disorders causing stroke is important for a correct diagnosis, for genetic counselling and, even if rarely, for a correct therapeutic management. Moreover, the genetics of complex diseases such the stroke, in which multiple genes interact with environmental risk factors to increase risk, has been revolutionized by the Genome-Wide Association Study (GWAS) approach. Scope of review Here we review the single-gene causes of ischemic stroke, bringing the reader from the candidate gene method toward the exciting new horizons of genetic technology. Major conclusions The aetiological diagnosis of ischemic stroke in young adults is more complex than in the elderly. The identification of a genetic cause is important to provide appropriate counseling and to start a correct therapy, when available. The advent of GWAS technology, such as for other complex pathological conditions, has contributed enormously to the understanding of many of these genetic bases. For success large, well phenotyped case cohorts are required, and international collaborations are essential. General significance This review focuses on the main causes of genetically-based ischemic stroke in young adults, often classified as indeterminate, investigating also the recent findings of the GWAS, in order to improve diagnostic and therapeutic management.

    In a series of 1-shot economic trust games in which participants could make real monetary profits, but also risked losing money, 2 studies compared young and older adults' trust (amount invested with trustees) and trustworthiness (amount returned to investors by trustees). In Study 1, young (n = 35) and older (n = 32) participants acted as investors, and the age of simulated trustees (young, older) was manipulated. In Study 2, young (n = 61) and older (n = 67) participants acted in real life as both investors and trustees. They completed 2 face-to-face trust games with same- and other-age partners, and 3 anonymous trust games with same-, other-, and unknown-age partners. Study 1 found that young and older participants rate older trustees as appearing more trustworthy than young trustees, but neither group invest more with older than young trustees. Rather, older participants were more likely than young participants to invest money averaged across trustee age. In Study 2, there were no age-related differences in trust, but older adults were more trustworthy than young adults in anonymous games with same- and unknown-age partners. It was also found that young adults demonstrate greater reputational concerns than older adults by reciprocating more trust when face-to-face than anonymous. We discuss the complex influences of age on trust game investing and reciprocation, as well as the implications for older adults' wellbeing and financial security.

  16. Treatment seeking for smoking cessation among young adults.

    PubMed

    Hughes, John R; Cohen, Bevin; Callas, Peter W

    2009-09-01

    Young adult smokers (18-24 year olds) do not seek treatment for smoking cessation as often as older smokers. Two commonly hypothesized reasons for this are that younger smokers are not aware of treatments or cannot afford them. The State of Vermont provides free smoking cessation treatment, and most young smokers are aware of this; thus, we tested whether young adult smokers from Vermont would still underutilize treatment via a secondary analysis of the population-based 2005 VT Adult Tobacco Survey. Young adult smokers from Vermont were less likely to have used medication (24% vs. 58%; relative risk = 0.42) or psychosocial (28% vs. 53%; relative risk = 0.54) treatment than middle-aged smokers (25-44 year olds). We conclude that reasons other than awareness and cost cause young adult smokers to not seek treatment. PMID:19195814

    PubMed

    Leenaars, A A

    1997-01-01

    A small but concerning percentage of completed suicides are seen as having left no clues. The classical case, albeit a literary one, is Robinson's Richard Cory. These people often dissemble, even about their suicide risk. An even smaller group of these individuals present themselves in therapy without communicating a sign of suicide risk. Utilizing an idiographic approach, the case of a young adult male (Rick) is presented. The narrative reconstruction gives voice behind the man's mask. The autopsy reveals a young man who was in deep pain and unable to adjust to life's demands. Rick lacked ego strength, being overly narcissistic and having deeply troubled, symbiotic attachments to his family in a world of interpersonal isolation. In the end, even the help of his therapist, who tried to reach through the mask, was not enough and Rick killed himself. The pain had become unbearable. A few guiding remarks for such cases are offered, noting that therapists must constantly address the dissembling in some suicidal patients. PMID:9112719

    Jennings, Zellyne

    2000-05-01

    Functional literacy is interpreted as the ability of the individual to apply skills in reading, writing, calculation and basic problem-solving in those activities in which literacy is required for effective functioning in his/her own group and community. The paper describes the rationale, development and administration of the test used for measuring levels (high, moderate, low) of achievement in functional literacy in three domains (document, prose and quantitative). An assumption of the study was that a high level of functional literacy was required for the individual to function effectively in his/her own group and community. The context of the study is Guyana the most underdeveloped and impoverished country in the English-speaking Caribbean. The subjects are out of school youth in Guyana aged 14-25. Amongst the main findings are: only approximately 11% of the young people show a high level of functional literacy; females tend to have a higher level of functional literacy than males: and most of those at the low level never went beyond primary and low status secondary schools and usually end up unemployed or in semi- or unskilled jobs. Attention is drawn to the difficulty of attracting funding for literacy programmes from international aid agencies, given the inflated adult literacy rate which is reported for Guyana in international statistics. While they credit Guyana with an adult literacy rate of 97.5%, the study suggests that a more realistic figure is in the 70s. The importance of adult and continuing education is underscored in view of the need to help those who are out of school to meet the ever-changing demands of society for improved skills in literacy and numeracy.

    Increased levels of neurotoxic amyloid-beta in the brain are a prominent feature of Alzheimer’s disease. FG-Loop (FGL), a neural cell adhesion molecule-derived peptide that corresponds to its second fibronectin type III module, has been shown to provide neuroprotection against a range of cellular insults. In the present study impairments in social recognition memory were seen 24 days after a 5 mg/15 µl amyloid-beta(25–35) injection into the right lateral ventricle of the young adult rat brain. This impairment was prevented if the animal was given a systemic treatment of FGL. Unbiased stereology was used to investigate the ability of FGL to alleviate the deleterious effects on CA1 pyramidal cells of the amyloid-beta(25–35) injection. NeuN, a neuronal marker (for nuclear staining) was used to identify pyramidal cells, and immunocytochemistry was also used to identify inactive glycogen synthase kinase 3beta (GSK3?) and to determine the effects of amyloid-beta(25–35) and FGL on the activation state of GSK3?, since active GSK3? has been shown to cause a range of AD pathologies. The cognitive deficits were not due to hippocampal atrophy as volume estimations of the entire hippocampus and its regions showed no significant loss, but amyloid-beta caused a 40% loss of pyramidal cells in the dorsal CA1 which was alleviated partially by FGL. However, FGL treatment without amyloid-beta was also found to cause a 40% decrease in CA1 pyramidal cells. The action of FGL may be due to inactivation of GSK3?, as an increased proportion of CA1 pyramidal neurons contained inactive GSK3? after FGL treatment. These data suggest that FGL, although potentially disruptive in non-pathological conditions, can be neuroprotective in disease-like conditions. PMID:23951173

    The ventrolateral division of the hypothalamic ventromedial nucleus (VMNvl) is a brain center for estrogen-dependent triggering of female sexual behavior upon progesterone receptor (PR) activation. We examined the agonistic and antagonistic actions of tamoxifen in this nucleus by analyzing its effects on the total number of PR-immunoreactive neurons, PR mRNA and protein levels, and subcellular location of PRs in ovariectomized Wistar rats. The results show that tamoxifen has no agonistic action in the number of PR-immunoreactive neurons, but increases PR expression and labeling in the nucleus and cytoplasm of VMNvl neurons that constitutively express PRs. As an antagonist, tamoxifen partially inhibited the estradiol-dependent increase in the number of PR-immunoreactive neurons and in PR mRNA and protein levels, without interfering with the subcellular location of the protein. We suggest that tamoxifen influence on PR expression in the VMNvl critically depends on the presence or absence of estradiol. PMID:26597778

  5. Acute genistein treatment mimics the effects of estradiol by enhancing place learning and impairing response learning in young adult female rats

    Endogenous estrogens have bidirectional effects on learning and memory, enhancing or impairing cognition depending on many variables, including the task and the memory systems that are engaged. Moderate increases in estradiol enhance hippocampus-sensitive place learning, yet impair response learning that taps dorsal striatum function. This memory modulation likely occurs via activation of estrogen receptors, resulting in altered neural function. Supplements containing estrogenic compounds from plants are widely consumed despite limited information about their effects on brain function, including learning and memory. Phytoestrogens can enter the brain and signal through estrogen receptors to affect cognition. Enhancements in spatial memory and impairments in executive function have been found following treatment with soy phytoestrogens, but no tests of actions on striatum-sensitive tasks have been made to date. The present study compared the effects of acute exposure to the isoflavone genistein with the effects of estradiol on performance in place and response learning tasks. Long-Evans rats were ovariectomized, treated with 17?-estradiol benzoate, genistein-containing sucrose pellets, or vehicle (oil or plain sucrose pellets) for two days prior to behavioral training. Compared to vehicle controls, estradiol treatment enhanced place learning at a low (4.5 ?g/kg) but not high dose (45 ?g/kg), indicating an inverted pattern of spatial memory facilitation. Treatment with 4.4 mg of genistein over two days also significantly enhanced place learning over vehicle controls. For the response task, treatment with estradiol impaired learning at both the low and high doses; likewise, genistein treatment impaired response learning compared to rats receiving vehicle. Overall, genistein was found to mimic estradiol-induced shifts in place and response learning, facilitating hippocampus-sensitive learning and slowing striatum-sensitive learning. These results suggest signaling through estrogen receptor ? and membrane-associated estrogen receptors in learning enhancements and impairments given the preferential binding of genistein to the ER? subtype and affinity for GPER.

    Overweight and obesity are a major concern in young adults. Technology has been integrated into many weight loss interventions; however little is known about the use of this technology in young adults. The purpose of this study was to explore through focus group sessions the opinions of young adults on the use of technology for weight loss. A total of 17 young adults, between 18 and 25 years of age, participated in three focus group sessions. Major results indicated that young adults have very little knowledge on the use of Smartphone technology for weight loss but would like to use this type of technology to help them lose weight. Results also indicated that young adults struggle to make healthy food choices and have priorities that outweigh exercise and they need support and guidance to make better decisions. In conclusion, young adults would be open to using Smartphone technology for weight loss but also need feedback and guidance to help make healthy decisions. PMID:25789170

    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. PMID:25494858

    Adolescent and young adults (AYAs) face challenges in having their cancers recognized, diagnosed, treated, and monitored. Monitoring AYA cancer survival is of interest because of the lack of improvement in outcome previously documented for these patients as compared with younger and older patient outcomes. AYA patients 15-39 years old, diagnosed during 2000-2008 with malignant cancers were selected from the SEER 17 registries data. Selected cancers were analyzed for incidence and five-year relative survival by histology, stage, and receptor subtypes. Hazard ratios were estimated for cancer death risk among younger and older ages relative to the AYA group. AYA survival was worse for female breast cancer (regardless of estrogen receptor status), acute lymphoid leukemia (ALL), and acute myeloid leukemia (AML). AYA survival for AML was lowest for a subtype associated with a mutation of the nucleophosmin 1 gene (NPM1). AYA survival for breast cancer and leukemia remain poor as compared with younger and older survivors. Research is needed to address disparities and improve survival in this age group. PMID:25417236

    Little attention has been paid to hearing abilities and the effects of noise on the normal adolescent and young adult population. A series of studies will be presented on the prevalence of hearing loss and reported effects of hearing loss and tinnitus in adolescents and young adults from different cultural backgrounds. Adolescents and young adults from different backgrounds may tend to seek or avoid various noise environments that could be detrimental to their hearing and cause tinnitus. Attitudes and exposures to noise environments were evaluated to see if these may be correlated with their hearing losses and/or tinnitus. In addition, these adolescent and young adult subjects reported how often they used hearing protection in various noise environments. Finally, the issues of quality of life and the need for hearing conservation programs with these populations will be presented.

    Despite developmental differences between young adults and adults, studies of condom use have not typically considered young adults as a distinct age group. This study sought to examine how condom use and its correlates differed between high-risk young adults and adults. Sexually transmitted infection (STI) clinic patients (n?=?763) reported STI history, contraception, negative condom attitudes, fear of partner reaction to condom use and risky behaviours. Past 3-month condom use was examined as unprotected vaginal sex (UVS) acts, proportional condom use and consistent condom use. Regression models tested associations of age group and potential correlates with each condom use outcome. Interaction models tested whether associations differed by age group. Proportional condom use was greater in young adults than adults (mean 0.55 vs. 0.47); UVS and consistent condom use were similar between age groups. Young adults with a recent STI reported less condom use, whereas for older adults, a distant STI was associated with less condom use, compared to others in their age groups. Negative condom attitudes were more strongly linked to UVS acts for younger versus older adults. STI prevention efforts for younger adults may be improved by intensifying counselling about condom use immediately following STI diagnosis and targeting negative condom attitudes. PMID:25070945

    In the U.S., cigar use doubled from 5.0 to 10.6 billion cigars consumed annually between 1997 and 2007, driven in large part by increased sales of cigarette-sized “little cigars” and narrow, mid-sized “cigarillos.” The present study examined prevalence of cigarillo use as well as attitudes, knowledge and behaviors related to cigarillo use among a sample of predominantly urban African American young adults 18–24 not in school and not employed. Survey data were collected from 131 young adults attending education and job training centers in Baltimore, Maryland and from 78 young adults attending education, job training, or recreational programs in Washington, D.C. In Baltimore, 22% of young adults had smoked a cigarillo in the past 30 days, compared with nearly 63% in D.C. Both populations were heavily exposed to cigarillo advertising and marketing. Cigarillo use in this urban young adult population is a growing public health problem and undermines the progress made in decreasing cigarette use. PMID:24185161

    2009-01-01

    Limited information exists on how adolescents decide to use complementary/alternative medicine (CAM). There are also no instruments specific to CAM, for the young adult population, which makes it difficult to explore knowledge in this area. The purpose of this study was to develop and examine the psychometric properties of the CAM Questionnaire for Young Adults which measures young adults’ attitudes about CAM. Participants for this cross-sectional survey were selected from enrolled undergraduate students at an urban university. Factor analysis identified three subscales: 1) positive beliefs about CAM; 2) environmental influence; and 3) psychological comfort. The scale has good internal consistency (Cronbach’s alpha = 0.79) and shows beginning demonstration of validity. Its use in this sample revealed that young adults who are female and have used CAM in the past for preventing or treating illness have the most positive attitude towards CAM and the greatest likelihood for continued use. The implication that prevention may play a role in young adults’ attitudes about CAM is a potential focus for future research. PMID:21614159

    Persimmon is widely eaten in Asia and the nutritional components of young and mature persimmons differ. Although raw young persimmon has a strong bitter taste and is difficult to eat, the beneficial health effects of young persimmon powder have attracted attention in recent years. Young persimmon has been suggested to have hypolipidemic activity as well as other biological effects. However, there has been little investigation of the beneficial effects of young persimmon. In the present study, we investigated the antioxidative effects of persimmon in an animal study and compared the effects of young persimmon and mature persimmon. Six-week-old male F344 rats were divided into three groups and fed a standard diet, young persimmon diet, or mature persimmon diet for 4 wk. The young persimmon and mature persimmon groups were fed a diet containing 5% (w/w) freeze-dried young or mature persimmon. We analyzed phosphatidylcholine hydroperoxide (PCOOH) levels in the rats as a biomarker of membrane lipid peroxidation. Our study showed that plasma PCOOH levels were significantly lower in the young persimmon group (36.1 ± 28.5 pmol/mL plasma) than in the control group (120 ± 66 pmol/mL plasma). No significant difference was observed between the mature persimmon group (57.3 ± 15.6 pmol/mL plasma) and the control group. It is possible that ascorbic acid and soluble tannin contribute to the difference in the antioxidant effects of young and mature persimmons. These results indicated that intake of young persimmon contributes to the reduction of plasma phospholipid hydroperoxide levels in rats. PMID:25994144

Associations between perceived behaviors of family, friends, and significant other and participants’ dietary behaviors were examined using t-tests and linear regressions. Results Young adults consumed more fast food if they perceived that their family, friends, or significant other did so (p < .003). Sugar-sweetened beverage consumption was associated with perceived consumption by family and friends (p < .034). Fruit and vegetable consumption and dinner preparation were associated with perceived behavior of friends only (p < .001). Conclusions Young adults’ dietary behaviors appear to reflect their perceptions of normative behavior, particularly among friends. PMID:24034689

  13. Young and Older Adults' Gender Stereotype in Multitasking

    PubMed Central

    Strobach, Tilo; Woszidlo, Alesia

    2015-01-01

    In the present study, we investigated discrepancies between two components of stereotyping by means of the popular notion that women are better at multitasking behaviors: the cognitive structure in individuals (personal belief) and the perceived consensus regarding certain beliefs (perceived belief of groups). With focus on this notion, we examined whether there was empirical evidence for the stereotype's existence and whether and how it was shared among different age groups. Data were collected from 241 young (n = 129) and older (n = 112) German individuals. The reported perceptions of gender effects at multitasking were substantial and thus demonstrated the existence of its stereotype. Importantly, in young and older adults, this stereotype existed in the perception of attributed characteristics by members of a collective (perceived belief of groups). When contrasting this perceived belief of groups and the personal belief, older adults showed a similar level of conformation of the gender stereotype while young adults were able to differentiate between these perspectives. Thus, young adults showed a discrepancy between the stereotype's components cognitive structure in individuals and perceived consensus regarding certain beliefs. PMID:26733913

  6. Predictors of Heterosexual Casual Sex Among Young Adults

    PubMed Central

    Manning, Wendy; Giordano, Peggy; Longmore, Monica

    2013-01-01

    Casual sex is often associated with the young adult stage in the life course. Most recent research on the prevalence, motives, and consequences of heterosexual casual sex has relied on samples of college students, yet students are only a small and advantaged subset of the young adult population. The current study drew on the Toledo Adolescent Relationships Study, which was collected in 2006–2007 and included young adults (ages 18–24 years) whose trajectories reflected a wider spectrum of educational experiences (N = 1,023). We moved beyond prior work by examining both frequency and type of heterosexual casual sex: lifetime vaginal, lifetime oral, and recent vaginal sex. We found that young adults enrolled or who graduated from 4-year educational institutions reported fewer casual sex partners on all three measures compared to participants with-out a high school degree and those with some college experience. Sexual attitudes were key factors mediating the association between educational status and casual sex behavior. These results indicate that programs aimed at encouraging healthy sexual behavior should target individuals who are at risk of not graduating high school because they are at greatest risk of frequent casual sex partners.

  11. Recruiting young adult cancer survivors for behavioral research.

    PubMed

    Rabin, Carolyn; Horowitz, Santina; Marcus, Bess

    2013-03-01

    Young adults have been dramatically underrepresented in cancer survivorship research. One contributing factor is the difficulty recruiting this population. To identify effective recruitment strategies, the current study assessed the yield of strategies used to recruit young survivors for an exercise intervention including: clinic-based recruitment, recruitment at cancer-related events, mailings, telephone-based recruitment, advertising on the internet, radio, television and social networking media, distributing brochures and word-of-mouth referrals. When taking into account the strategies for which we could track the number of survivors approached, recruitment at an oncology clinic was the most productive: 38 % of those approached were screened and 8 % enrolled. When evaluating which strategy yielded the greatest percentage of the sample, however, mailings were the most productive. Given widespread use of the internet and social networking by young adults, investigators should also consider these low-cost recruitment strategies. PMID:22810954

  14. Aging-Dependent Changes in the Radiation Response of the Adult Rat Brain

    SciTech Connect

    Schindler, Matthew K. Forbes, M. Elizabeth; Robbins, Mike E.; Riddle, David R.

    2008-03-01

    Purpose: To assess the impact of aging on the radiation response in the adult rat brain. Methods and Materials: Male rats 8, 18, or 28 months of age received a single 10-Gy dose of whole-brain irradiation (WBI). The hippocampal dentate gyrus was analyzed 1 and 10 weeks later for sensitive neurobiologic markers associated with radiation-induced damage: changes in density of proliferating cells, immature neurons, total microglia, and activated microglia. Results: A significant decrease in basal levels of proliferating cells and immature neurons and increased microglial activation occurred with normal aging. The WBI induced a transient increase in proliferation that was greater in older animals. This proliferation response did not increase the number of immature neurons, which decreased after WBI in young rats, but not in old rats. Total microglial numbers decreased after WBI at all ages, but microglial activation increased markedly, particularly in older animals. Conclusions: Age is an important factor to consider when investigating the radiation response of the brain. In contrast to young adults, older rats show no sustained decrease in number of immature neurons after WBI, but have a greater inflammatory response. The latter may have an enhanced role in the development of radiation-induced cognitive dysfunction in older individuals.

  15. Muscle dissatisfaction in young adult men

    2006-01-01

    Backround Appearance concerns are of increasing importance in young men's lives. We investigated whether muscle dissatisfaction is associated with psychological symptoms, dietary supplement or anabolic steroid use, or physical activity in young men. Methods As a part of a questionnaire assessment of health-related behaviors in the population-based FinnTwin16 study, we assessed factors associated with muscle dissatisfaction in 1245 men aged 22–27 using logistic regression models. Results Of men, 30% experienced high muscle dissatisfaction, while 12% used supplements/steroids. Of highly muscle-dissatisfied men, 21.5% used supplements/steroids. Mean body mass index, waist circumference, or leisure aerobic activity index did not differ between individuals with high/low muscle dissatisfaction. Muscle dissatisfaction was significantly associated with a psychological and psychosomatic problems, alcohol and drug use, lower height satisfaction, sedentary lifestyle, poor subjective physical fitness, and lower life satisfaction. Conclusion Muscle dissatisfaction and supplement/steroid use are relatively common, and are associated with psychological distress and markers of sedentary lifestyle. PMID:16594989

    2013-01-01

    Objective Though children with attention-deficit/hyperactivity disorder (ADHD) are at risk for impulsive, health-endangering behavior, few studies have examined non-substance use-related risk-taking behaviors. This study examined whether adolescents and young adults with ADHD histories were more likely than those without ADHD histories to report frequent engagement in motorsports, a collection of risky driving-related activities associated with elevated rates of physical injury. Path analyses tested whether persistent impulsivity, comorbid conduct disorder or antisocial personality disorder (CD/ASP), and heavy alcohol use mediated this association. Analyses also explored whether frequent motorsporting was associated with unsafe and alcohol-influenced driving. Method Two-hundred and twenty-one adolescent and young adult males (16–25 years-old) diagnosed with ADHD in childhood and 139 demographically-similar males without ADHD histories reported their motorsports involvement. Persistent impulsivity, CD/ASP, heavy drinking, and hazardous driving were also measured in adolescence/young adulthood1 Results Adolescents and young adults with ADHD histories were more likely to report frequent motorsports involvement than those without childhood ADHD. Impulsivity, CD/ASP and heavy drinking partially mediated this association, such that individuals with ADHD histories, who had persistent impulsivity or CD/ASP diagnoses, were more likely to engage in heavy drinking, which was positively associated with frequent motorsporting. Motorsports involvement was associated with more unsafe and alcohol-influenced driving, and this association was more often found among those with, than without, ADHD histories. Conclusions Adolescents and young adults with ADHD histories, especially those with persisting impulsivity, comorbid CD/ASP and heavy drinking tendencies, are more likely to engage in motorsports, which may heighten risk of injury.

  5. Visual statistical learning in children and young adults: how implicit?

    PubMed Central

    Bertels, Julie; Boursain, Emeline; Destrebecqz, Arnaud; Gaillard, Vinciane

    2015-01-01

    Visual statistical learning (VSL) is the ability to extract the joint and conditional probabilities of shapes co-occurring during passive viewing of complex visual configurations. Evidence indicates that even infants are sensitive to these regularities (e.g., Kirkham et al., 2002). However, there is continuing debate as to whether VSL is accompanied by conscious awareness of the statistical regularities between sequence elements. Bertels et al. (2012) addressed this question in young adults. Here, we adapted their paradigm to investigate VSL and conscious awareness in children. Using the same version of the paradigm, we also tested young adults so as to directly compare results from both age groups. Fifth graders and undergraduates were exposed to a stream of visual shapes arranged in triplets. Learning of these sequences was then assessed using both direct and indirect measures. In order to assess the extent to which learning occurred explicitly, we also measured confidence through subjective measures in the direct task (i.e., binary confidence judgments). Results revealed that both children and young adults learned the statistical regularities between shapes. In both age groups, participants who performed above chance in the completion task had conscious access to their knowledge. Nevertheless, although adults performed above chance even when they claimed to guess, there was no evidence of implicit knowledge in children. These results suggest that the role of implicit and explicit influences in VSL may follow a developmental trajectory. PMID:25620943

  6. Declining Alternative Reinforcers Link Depression to Young Adult Smoking

    2010-01-01

    Aims Young adulthood represents a period of continued smoking progression and the establishment of regular and long-term smoking practices. Our understanding of the psychological processes that facilitate and solidify regular smoking patterns in this developmental period is limited. We sought to evaluate the role of depression symptoms in young adult smoking uptake and to evaluate whether non-smoking related alternative reinforcers was a mechanism by which depression symptoms influence smoking. Participants The sample was composed of 834 young adults who participated in a longitudinal study of smoking adoption (age 18 – 22 years old). Design and measurements In this prospective cohort study, smoking, depression, alternative reinforcers and several covariates were measured annually via telephone from emerging adulthood (age 18) to young adulthood (age 22). Findings Results of a parallel processes latent growth curve model showed that depression symptoms level (baseline age 18) had a significant negative effect on substitute alternative reinforcers trend (? = ?.01, z=?3.17, p=.002) and that substitute reinforcers trend had a significant negative effect on smoking trend (? = ?.62, z= ?2.99, p=.003). An assessment of indirect effects revealed that depression symptoms level had a significant positive indirect effect on smoking trend through substitute alternative reinforcers trend (B = .01, z = 2.09, p=.04, 99% CI = .001, .02), such that greater depression symptoms at baseline predicted decreases in substitute reinforcers across time which in turn predicted increases in smoking uptake/rate from emerging to young adulhood. Conclusions Depression symptoms in emerging adulthood indirectly influence smoking and mitigating declines and/or promoting greater alternative reinforcers to smoking may prevent smoking uptake and further increases in smoking rate among young adults.

    Schema-consistent material that is aligned with an individual's knowledge and experience is typically more memorable than abstract material. This effect is often more extreme in older adults and schema use can alleviate age deficits in memory. In three experiments, young and older adults completed memory tasks where the availability of schematic information was manipulated. Specifying nonobvious relations between to-be-remembered word pairs paradoxically hindered memory (Experiment 1). Highlighting relations within mixed lists of related and unrelated word pairs had no effect on memory for those pairs (Experiment 2). This occurred even though related word pairs were recalled better than unrelated word pairs, particularly for older adults. Revealing a schematic context in a memory task with abstract image segments also hindered memory performance, particularly for older adults (Experiment 3). The data show that processing schematic information can come with costs that offset mnemonic benefits associated with schema-consistent stimuli. PMID:25980799

    The inherited bone marrow failure syndromes are a diverse group of genetic diseases associated with inadequate production of one or more blood cell lineages. Examples include Fanconi anemia, dyskeratosis congenita, Diamond-Blackfan anemia, thrombocytopenia absent radii syndrome, severe congenital neutropenia, and Shwachman-Diamond syndrome. The management of these disorders was once the exclusive domain of pediatric subspecialists, but increasingly physicians who care for adults are being called upon to diagnose or treat these conditions. Through a series of patient vignettes, we highlight the clinical manifestations of inherited bone marrow failure syndromes in adolescents and young adults. The diagnostic and therapeutic challenges posed by these diseases are discussed. PMID:24888387

    Postprandial lipemia has been associated with acute endothelial dysfunction. Endothelial dysfunction, in turn, is associated with increased arterial stiffness. However, the relationship between postprandial lipemia and acute changes in arterial stiffness has not been extensively investigated. Therefore, we conducted a pilot study on the effects of postprandial lipemia on arterial stiffness in 19 healthy young adults before and after consumption of a high-fat mixed meal. Arterial stiffness was assessed locally with echo-tracking carotid arterial strain (CAS) and globally with carotid-femoral pulse wave velocity (PWV). As assessed by these two benchmark parameters, arterial stiffness did not differ significantly postprandially. However, the arterial distension period (ADP) was significantly lower 2 hours after mixed meal ingestion. In addition, slopes of carotid artery area (CAA) curves were significantly steeper postprandially. Therefore, we concluded that ADP may be a more sensitive marker of arterial stiffness in healthy young adults when compared to PWV and CAS. PMID:26060082

    Abstract Current findings suggest that mother's marital status indicating father's absence or conflicting relationship to father may be specifically related to dissociation and other stress-related symptoms. We have assessed relationships of mother's marital status, dissociative symptoms, and other psychopathological manifestations in a sample of 19 years’ old young adults (N?=?364) participating in European longitudinal study (European Longitudinal Study of Parenthood and Childhood). The results show clinically significant manifestations of dissociative symptoms in young adult men whose mothers were fatherless and in women whose mothers were re-married. Other psychopathological symptoms did not reach clinically significant manifestations. The results suggest that significant factor related to high level of dissociative symptoms in men growing in fatherless families might be linked with disturbed and conflicting attachment to a father's figure and pathological dependent attachment to mother. In women dissociative symptoms likely are linked to conflicting relationship between mother and daughter associated with stepfather’ presence in the family. PMID:25590849

    rising prevalence of food hypersensitivity (FHS) and severe allergic reactions to foods have been reported in the last decade. However, little is known on the prevalence in young adults. This study estimated the prevalence of FHS to the most common allergenic foods in an unselected population of young adults. We investigated a cohort of 1272 young adults 22 years of age by questionnaire, skin prick test (SPT) and histamin release (HR) followed by oral challenge to the most common allergenic foods. FHS was divided into primary and secondary FHS. Primary FHS was defined as being independent of pollen sensitization, whereas secondary FHS was defined as reactions to pollen related fruits and vegetables in pollen allergic patients. The questionnaire was returned by 77.1%. Primary FHS was reported by 19.6% and secondary FHS by 16.7% of the participants. Confirmed primary FHS by oral challenge was 1.7% [1.1% - 2.95%]. In primary FHS, the most common allergenic food was peanut (0.6%) followed by additives (0.5%), shrimp (0.2%), codfish (0.1%), cow's milk (0.1%), octopus (0.1%) and soy (0.1%). In secondary FHS, kiwi allergy was reported by 7.8% of the participants followed by hazelnut (6.6%), pineapple (4.4%), apple (4.3%), orange (4.2%), tomato (3.8%), peach (3.0%) and brazil nut (2.7%). This study found a 1.7% [1.1% - 2.95%] prevalence of primary FHS confirmed by oral challenge to the most common allergenic foods in an unselected population of young adults. PMID:19594854

    AIM: To assess the correlation between blood pressure levels and fasting plasma glucose levels among young adults attending Chatrapati Shahuji Maharaj University, Kanpur, India. METHODS: The present study was cross-sectional in nature, conducted among students in the Institute of Paramedical Sciences, Chatrapati Shahuji Maharaj University, Kanpur. Study subjects included 185 young adults. Among them, 94 were males and 91 were females, in the age group 17 to 19 years. RESULTS: Mean age among males was 18.5 ± 1.5 years and among females was 17.9 ± 1.8 years. Of the total 185 study subjects, 61 (32.9%) were classified as pre-diabetic and 20 (10.8%) as pre-hypertensive. Mean waist circumference, systolic blood pressure and serum high density lipoprotein did not vary significantly between normoglycemic and pre-diabetic subjects. However, the mean diastolic blood pressure of pre-diabetics (82 ± 5 mmHg) was significantly higher than normoglycemics (79 ± 6 mmHg). Mean serum cholesterol, serum triglycerides, serum low density lipoprotein (LDL) and serum very low density lipoprotein was also higher among pre-diabetic subjects in comparison to normoglycemic subjects and the difference was statistically significant. Upon multiple linear regression analysis, it was observed that body mass index (BMI) (? = 0.149), diastolic blood pressure (? = 0.375) and serum LDL (? = 0.483) were significantly associated with fasting plasma glucose. Multiple linear regression with diastolic blood pressure as the outcome variable showed that BMI (? = 0.219), fasting blood glucose (? = 0.247) and systolic blood pressure (? = 0.510) were significantly associated. CONCLUSION: A significant prevalence of pre-diabetes and pre-hypertension in young adults is a matter of concern therefore all young adults need to be targeted for screening of diabetes and hypertension and lifestyle modification.

    2015-04-01

    In the era of an ageing population, young adults on medical wards are quite rare, as only 12% of young adults report a long-term illness or disability. However, mental health problems remain prevalent in the younger population. In a recent report, mental health and obesity were listed as the most common problems in young adults. Teams set up specifically for the needs of younger adults, such as early intervention in psychosis services are shown to work better than traditional care and have also proven to be cost effective. On the medical wards, younger patients may elicit strong emotions in staff, who often feel protective and may identify strongly with the young patient's suffering. In order to provide holistic care for young adults, general physicians need to recognise common presentations of mental illness in young adults such as depression, deliberate self-harm, eating disorders and substance misuse. Apart from treating illness, health promotion is particularly important for young adults. PMID:25824067

    This study tested parental loneliness, family of origin environment, and a history of being bullied as predictors of loneliness in young adults. The role of social skills in young adults' loneliness was also examined. Participants were 111 young-adult-parent dyads who completed measures of loneliness and the family communication environment. In addition, young adults completed measures of social skills and history of being bullied. Predictions were tested with structural equation modeling, path analysis, and multiple regression analysis. Results showed that parental loneliness and a history of being bullied were each significant predictors of young adult loneliness. A family environment that supported open communication was negatively associated with young adults' loneliness. Parental loneliness and a history of being bullied each had direct effects on young adults' loneliness as well as indirect effects through reduced social skills. PMID:22303616

    Purpose The purpose of this study was to characterize the verbal memory limitations of young adults with language learning disability (LLD). Method Sixteen young adults with LLD and 34 age- and education-matched controls with typical language participated in a Deese–Roediger–McDermott (DRM; Deese, 1959; Roediger & McDermott, 1995) list recall experiment. Participants listened to 12-item word lists that converged on a nonpresented critical item (e.g., rain) semantically (umbrella, drench, weather, hail), phonologically (train, main, ran, wren), or dually in a hybrid list (umbrella, train, drench, main) and recalled words in no particular order. Group comparisons were made on veridical recall (i.e., words that were presented) and false recall of nonpresented critical items. Recall performance was analyzed by list type and list position to examine potential differences in the quality of memorial processes. Results The LLD group produced fewer veridical recalls than the controls. Both groups demonstrated list type and list position effects in veridical recall. False recall of the critical items was comparable in the 2 groups and varied by list type in predictable ways. Conclusion Young adults with LLD have verbal memory limitations characterized by quantitatively low levels of accurate recall. Qualitative patterns of recall are similar to those of unaffected peers. Therefore, the memory problem is characterized by limited capacity; memorial processes appear to be intact. PMID:25652445

    Exercise seems a simple and widely practised behaviour that activates molecular and cellular signalling cascades involved in various central nervous system processes. Despite impressive results obtained in animal studies, fitness interventions have produced less reliable effects in humans, particularly in young adults. In the present study we tested the hypothesis that an individually adapted exercise training consisting of three running sessions of 30 minutes per week for 6 weeks, has the potential to improve visuospatial and verbal memory, concentration performance, and affect in young and healthy adults. Twenty-eight students participated and underwent a graded fitness test to assess individual fitness. The experimental group took part in an aerobic running programme, whereas the control group were asked not to vary their everyday activities. We found a significant increase in visuospatial memory performance and a significant increase in positive affect on a .05 alpha level of significance. However, we observed no effects of running training on concentration performance and verbal memory. We conclude that physical activity can possibly serve as a means to improve positively valenced aspects of affect and benefit visuospatial but not verbal memory in young adults. PMID:18609015

    Background: In China, suicide is one of the major causes of death among adolescents and young adults aged 15 to 34 years. Aim: The current study examines how risk factors vary by age groups in rural China, referring to those aged 15 to 24 years and those aged 25 to 34 years. Method: A case-control psychological autopsy (PA) study is conducted in sixteen counties from three Chinese provinces, including 392 suicide cases and 416 community living controls in the sample. Results: In China, young adults aged 25 to 34 years have a higher risk for suicide than adolescents aged 15 to 24 years, and it holds true even controlling for relevant social factors. In addition, age-related factors such as education, marital status, whether having children, status in the family, physical health, and personal income all have varying degrees of impact on suicide risks for rural youth. Conclusions: This study shows that there are some age-related risk factors for suicide at certain life stages and emphasizes that young adults in rural China aged 25 to 34 years have an increased risk of suicide as a result of experiencing more psychological strains with age.

    Young adult involvement in sexual behavior typically occurs within a relationship context, but we know little about the ways in which specific features of romantic relationships influence sexual decision-making. Prior work on sexual risk taking focuses attention on health issues rather than relationship dynamics. We draw on data from the Toledo Adolescent Relationships Study (TARS) (n = 475) to examine the association between qualities and dynamics of current/most recent romantic relationships such as communication and emotional processes, conflict, demographic asymmetries, and duration and the management of sexual risk. We conceptualize ‘risk management’ as encompassing multiple domains, including (1) questioning the partner about previous sexual behaviors/risks, (2) using condoms consistently, and (3) maintaining sexual exclusivity within the relationship. We identify distinct patterns of risk management among dating young adults and find that specific qualities and dynamics of these relationships are linked to variations in risk management. Results from this paper suggest the need to consider relational dynamics in efforts to target and influence young adult sexual risk-taking and reduce STIs, including HIV. PMID:23805015

  6. Anatomical gradients of adult neurogenesis and activity: young neurons in the ventral dentate gyrus are activated by water maze training

    Hippocampal function varies in a subregion-specific fashion: spatial processing is thought to rely on the dorsal hippocampus, while anxiety-related behavior relies more on the ventral hippocampus. During development, neurogenesis in the dentate gyrus proceeds along ventral to dorsal as well as suprapyramidal to infrapyramidal gradients, but it is unclear whether regional differences in neurogenesis are maintained in adulthood. Moreover, it is unknown whether young neurons in the adult exhibit subregion-specific patterns of activation. We therefore examined the magnitude of neurogenesis and the activation of young and mature granule cells in dentate gyrus subregions in adult rats that learned a spatial water maze task, swam with no platform, or were left untouched. We found that both adult neurogenesis and granule cell activation, as defined by c-fos expression in the granule cell population as a whole, were higher in the dorsal than the ventral dentate gyrus. In contrast, c-fos expression in adult-born granule cells, identified by PSA-NCAM or location in the subgranular zone, occurred at a higher rate in the opposite subregion, the ventral dentate gyrus. Interestingly, c-fos expression in the entire granule cell population was equivalent in water maze-trained rats and swim control rats, but was increased in the young granule cells only in the learning condition. These results provide new evidence that hippocampally-relevant experience activates young and mature neurons in different dentate gyrus subregions and with different experiential specificity, and suggest that adult-born neurons may play a specific role in anxiety-related behavior or other non-spatial aspects of hippocampal function.

    Delta EEG power density, which has been viewed as a measure of intensity of NREM sleep, declines across the lifetime in humans, cats, and hamsters, but data in rats have been unclear. It is also uncertain whether older rats differ from younger animals in the degree of change in delta power during recovery sleep following short-term sleep deprivation. We have examined delta power density in NREM sleep under baseline conditions and following 48 h of sleep deprivation in young (3 months), middle-aged (12 months), and older (24 months) rats. The presence or absence of age effects was highly dependent on the method of normalizing the data. When expressed as a fraction of total NREM EEG power, there was no age effect on baseline delta power density, or on the change from baseline to recovery conditions. When expressed as a multiple of delta power in REM under the same condition, the younger rats had higher delta power density than the middle-aged and older rats. For all the ages combined, there was an increase in delta power density in the recovery condition. When examined by age, the younger rats (which started from a higher level of delta power density than the other groups) did not have an increase in delta during recovery; the middle-aged rats tended to, and the older rats (which started from lower baseline levels) significantly increased delta power density in the recovery condition. This suggests that the lower delta power seen during baseline in older rats is not due to decreased ability to generate delta activity. PMID:10674433

  8. Effects of Chronic Fluoxetine Treatment on Neurogenesis and Tryptophan Hydroxylase Expression in Adolescent and Adult Rats

    2014-01-01

    The antidepressant drug fluoxetine (Prozac) has been increasingly prescribed to children and adolescents with depressive disorders despite a lack of thorough understanding of its therapeutic effects in the paediatric population and of its putative neurodevelopmental effects. Within the framework of PRIOMEDCHILD ERA-NET, we investigated; a) effects of chronic fluoxetine treatment on adult hippocampal neurogenesis, a structural readout relevant for antidepressant action and hippocampal development; b) effects on tryptophan hydroxylase (TPH) expression, a measure of serotonin synthesis; c) whether treatment effects during adolescence differed from treatment at an adult age, and d) whether they were subregion-specific. Stereological quantification of the number of proliferating (Ki-67+) cells and of the number of young migratory neurons (doublecortin+), revealed a significant age-by-treatment interaction effect, indicating that fluoxetine affects both proliferation and neurogenesis in adolescent-treated rats differently than it does in adult-treated rats. In terms of subregional differences, fluoxetine enhanced proliferation mainly in the dorsal parts of the hippocampus, and neurogenesis in both the suprapyramidal and infrapyramidal blades of the dentate gyrus in adolescent-treated rats, while no such differences were seen in adult-treated rats. Fluoxetine exerted similar age-by-treatment interaction effects on TPH cells mainly in the ventral portion of the dorsal raphe nucleus. We conclude that fluoxetine exerts divergent effects on structural plasticity and serotonin synthesis in adolescent versus adult-treated rats. These preliminary data indicate a differential sensitivity of the adolescent brain to this drug and thus warrant further research into their behavioural and translational aspects. Together with recent related findings, they further call for caution in prescribing these drugs to the adolescent population. PMID:24827731

    Background The benefits of healthy habits are well-established, but it is unclear whether making health behavior changes as an adult can still alter coronary artery disease risk. Methods and Results The Coronary Artery Risk Development in Young Adults (CARDIA) prospective cohort study (n = 3538) assessed 5 healthy lifestyle factors (HLFs) among young adults between ages 18–30 (Year 0 baseline) and 20 years later (Year 20): not overweight/obese, low alcohol intake, healthy diet, physically active, nonsmoker. We tested whether change from Year 0 to 20 in a continuous composite HLF score (HLF change; range: ?5 to +5) is associated with subclinical atherosclerosis [coronary artery calcification (CAC) and carotid intima-media thickness (IMT)] at Year 20, after adjustment for demographics, medications, and baseline HLFs. By Year 20, 25·3% of the sample improved (HLF change ? +1); 40·4% deteriorated (had fewer HLFs); 34·4% stayed the same; 19·2% had CAC (>0). Each increase in HLFs was associated with reduced odds of detectable CAC (OR = .85, 95% CI: .74 – .98) and lower IMT (carotid bulb ? = ?.024, p = 0.001), and each decrease in HLFs was predictive to a similar degree of greater odds of CAC (OR = 1.17, 95% CI: 1.02 – 1.33) and greater IMT (? = +.020, p < 0.01). Conclusions Healthy lifestyle changes during young adulthood are associated with decreased, and unhealthy lifestyle changes with increased risk for subclinical atherosclerosis in middle age.

    (3H)Trioleyl glycerol (TO) and (14C)vitamin D3 were perfused intraduodenally for 5 hr in aged (19-21 months) and young adult (4-5 months) Sprague-Dawley rats. The rate of intestinal uptake from the gastrointestinal lumen and transport into the body of these lipids were decreased in the aged animals. Since the distribution of TO lipolytic products in the lumen was unchanged, reduced intestinal uptake rate probably occurred at the mucosal membrane. Furthermore, in the aged rats, the rate of transintestinal transport of both trioleyl glycerol and vitamin D3 was impaired. No evidence for impaired mucosal TO reesterification or for accumulation of vitamin D3 metabolites was found, suggesting that intestinal lipid accumulation resulted from a defect in lipoprotein assembly or in discharge from the mucosal cell. Impaired absorption of lipids may contribute to malnutrition and osteopenia of advancing age.

    Background The relationship between obesity and asthma is an area of debate. Objective To investigate the association of elevated body mass index (BMI) at a young age and young adult asthma. Methods BMI, questionnaires, and serologic tests results were analyzed in participants of a predominantly white, middle-class, population-based birth cohort from Detroit, Michigan at 6 to 8 and 18 years of age. Asthma diagnosis was based on medical record data. Allergen specific IgE was analyzed using UniCAP, with atopy defined as 1 or more allergen specific IgE levels of 0.35 kU/L or higher. Overweight was defined as a BMI in 85th percentile or higher. Results A total of 10.6% of overweight males at 6 to 8 years of age had current asthma at 18 to 20 years of age compared with 3.2% of males who were normal or underweight (relative risk [RR], 3.3; 95% confidence interval [CI], 1.0–11.0; P=.048). A total of 19.6% of females who were overweight at 6 to 8 years of age had asthma compared with 10.3% of females who were normal or underweight (RR, 1.9; 95% CI, 0.9–3.9; P=.09). After adjustment for atopy at 6 to 8 years of age, overweight males had an adjusted RR of 4.7 (95% CI, 1.4–16.2; P=.01), and overweight females had an adjusted RR of 1.7 (95% CI, 0.8–3.3; P=.15). Change in BMI between 6 to 8 years of age and 18 to 20 years of age was also examined. Patients with persistently elevated BMI exhibited increased risk of asthma as young adults (RR, 2.4; 95% CI, 1.2–4.7) but not with an increasing BMI (RR, 0.8; 95% CI, 0.3–2.2) or a decreasing BMI (RR, 0.8; 95% CI, 0.3–2.2). Conclusion Overweight males 6 to 8 years of age have increased risk of asthma as young adults. Being overweight remains a predictor of asthma after adjustment for early atopy. A similar but not statistically significant trend was also seen among overweight females. Overweight body habitus throughout childhood is a risk factor for young adult asthma. PMID:23176878

    Our experiments, carried out at night and during the day on adults and laboratory-born young of the sandhopper Talitrus saltator, deal with the identification and use of the moon as an orientating factor. Sandhoppers were released in an apparatus (a Plexiglas dome) that produced a scenario similar to the natural one (with artificial sky, moon or sun illuminated at different intensities). When tested at night, the adult and young sandhoppers used the artificial moon like the natural one, independently of the intensity of illumination of the artificial sky and moon. In other words, sandhoppers tested at night always identified the artificial moon as the moon and never as the sun. In daytime releases, the seaward orientation failed at low intensities of artificial sky and sun illumination (3.07 and 1.55 microW cm2, respectively), whereas the sun compass was used effectively at higher levels of artificial sun and sky illumination. The innate ability of moon compass orientation in inexpert young sandhoppers was demonstrated even under artificial light. PMID:16188607

    Purpose Indoor tanning (IT) increases risk for melanoma and is particularly common among young adult women. IT has also been linked with some psychiatric symptoms, and frequent tanning may indicate tanning dependence (addiction) associated with endorphin release during ultraviolet (UV) radiation exposure. The objective of the current study was to investigate associations between IT, tanning dependence, and psychiatric and substance use symptoms in young adult women. Design Cross-sectional survey and psychiatric interview. Setting Online, except for the MINI International Neuropsychiatric Interview (MINI) that was completed over the telephone. Subjects Participants were 306 female university students aged 18–25 years. Measures MINI, Seasonal Scale Index, tanning dependence scales, reporting ever having used a tanning bed or booth with tanning lamps (single item), reporting smoking a cigarette in the last 30 days (single item). Analysis Descriptive statistics, chi square analysis, multivariate logistic regression. Results Forty-six percent of the sample reported a history of IT, and 25% were classified as tanning dependent. Multivariate logistic regression analyses showed that IT was significantly associated with symptoms of alcohol use disorders, generalized anxiety, and not having social anxiety. Tanning dependence was associated with symptoms of alcohol use disorders. Conclusion Tanning is of concern not only for its association with skin cancer but for its association with psychiatric and substance use symptoms. Young women with certain psychological problems may seek relief from their symptoms by IT. These findings suggest that indoor tanners may benefit from health behavior and other psychosocial interventions. PMID:23621780

    This study examined vowel perception by young normal-hearing (YNH) adults, in various listening conditions designed to simulate mild-to-moderate sloping sensorineural hearing loss. YNH listeners were individually age- and gender-matched to young hearing-impaired (YHI) listeners tested in a previous study [Richie et al., J. Acoust. Soc. Am. 114, 2923-2933 (2003)]. YNH listeners were tested in three conditions designed to create equal audibility with the YHI listeners; a low signal level with and without a simulated hearing loss, and a high signal level with a simulated hearing loss. Listeners discriminated changes in synthetic vowel tokens /smcapi e ? invv æ/ when F1 or F2 varied in frequency. Comparison of YNH with YHI results failed to reveal significant differences between groups in terms of performance on vowel discrimination, in conditions of similar audibility by using both noise masking to elevate the hearing thresholds of the YNH and applying frequency-specific gain to the YHI listeners. Further, analysis of learning curves suggests that while the YHI listeners completed an average of 46% more test blocks than YNH listeners, the YHI achieved a level of discrimination similar to that of the YNH within the same number of blocks. Apparently, when age and gender are closely matched between young hearing-impaired and normal-hearing adults, performance on vowel tasks may be explained by audibility alone.

    The objective of this study was to characterize responses of adult rats to one and two weeks of whole body suspension. Body weights and food and water intakes were initially reduced during suspension, but, while intake of food and water returned to presuspension levels, body weight remained depressed. Diuresis was evident, but only during week two. Hindlimb muscle responses were differential, with the soleus exhibiting the greatest atrophy and the EDL a relative hypertrophy. These findings suggest that adult rats respond qualitatively in a manner similar to juveniles during suspension.

    Objectives: Orthodontic treatment need has often been assessed in child populations, but few studies employing internationally-recognized indices have been conducted in adult or young adult populations. The aim of this study was to determine the orthodontic treatment need of a young adult population in Spain by means of the Dental Aesthetic Index (DAI), the Index of Orthodontic Treatment Need (IOTN) and the need perceived by the patients. Study design: A cross-sectional epidemiological study was conducted in a broad, representative sample of 671 adults aged between 35 and 44 years using health centers in the Valencia Region of Spain, following the recommendations of the World Health Organization (WHO). Results: Orthodontic treatment was required by 31.3% of the sample according to the DAI and 19.2% according to the IOTN (DHC). The orthodontic treatment need perceived by the patients was 21.1%. On relating treatment need to different variables, significant differences in patient perception were encountered by gender, as women perceived a greater need (23.9%) than men (14.4%). Significant differences in previous orthodontic treatment history were found between middle/high (15%) and low (9%) social class and between secondary/tertiary (14%) and primary (3.3%) education. Conclusions: There was no agreement between the treatment need assessed objectively by the indices and that perceived by the patient, or between the indices themselves. The decision to undergo orthodontic treatment can depend on socioeconomic and psychological factors and on values and principles that do not easily lend themselves to objective measurement. Key words:Orthodontics, epidemiology, adult, malocclusion. PMID:22322504

    The emotions evoked by music can enhance recognition of excerpts. It has been suggested that memory is better for high than for low arousing music (Eschrich et al., 2005; Samson et al., 2009), but it remains unclear whether positively (Eschrich et al., 2008) or negatively valenced music (Aubé et al., 2013; Vieillard and Gilet, 2013) may be better recognized. Moreover, we still know very little about the influence of age on emotional memory for music. To address these issues, we tested emotional memory for music in young and older adults using musical excerpts varying in terms of arousal and valence. Participants completed immediate and 24 h delayed recognition tests. We predicted highly arousing excerpts to be better recognized by both groups in immediate recognition. We hypothesized that arousal may compensate consolidation deficits in aging, thus showing more prominent benefit of high over low arousing stimuli in older than younger adults on delayed recognition. We also hypothesized worst retention of negative excerpts for the older group, resulting in a recognition benefit for positive over negative excerpts specific to older adults. Our results suggest that although older adults had worse recognition than young adults overall, effects of emotion on memory do not seem to be modified by aging. Results on immediate recognition suggest that recognition of low arousing excerpts can be affected by valence, with better memory for positive relative to negative low arousing music. However, 24 h delayed recognition results demonstrate effects of emotion on memory consolidation regardless of age, with a recognition benefit for high arousal and for negatively valenced music. The present study highlights the role of emotion on memory consolidation. Findings are examined in light of the literature on emotional memory for music and for other stimuli. We finally discuss the implication of the present results for potential music interventions in aging and dementia. PMID:25814950

    Cancer registries are an important research resource that facilitate the study of etiology, tumor biology, patterns of delayed diagnosis and health planning needs. When outcome data are included, registries can track secular changes in survival related to improvements in early detection or treatment. The surveillance, epidemiology, and end results (SEER) registry has been used to identify major gaps in survival for older adolescent and young adult (AYA) patients compared with younger children and older adults. In order to determine the reasons for this gap, the complete registration and accurate classification of AYA malignancies is necessary. There are inconsistencies in defining the age limits for AYAs although the Adolescent and Young Adult Oncology Progress Review Group proposed a definition of ages 15 through 39 years. The central registration and classification issues for AYAs are case-finding, defining common data elements (CDE) collected across different registries and the diagnostic classification of these malignancies. Goals to achieve by 2010 include extending and validating current diagnostic classification schemes and expanding the CDE to support AYA oncology research, including the collection of tracking information to assess long-term outcomes. These efforts will advance preventive, etiologic, therapeutic, and health services-related research for this understudied age group. PMID:18360832

    Maternal separation (MatSep) is a model of behavioral stress during early life. We reported that MatSep exacerbates ANG II-induced hypertension in adult male rats. The aims of this study were to determine whether exposure to MatSep in female rats sensitizes blood pressure to ANG II infusion similar to male MatSep rats and to elucidate renal mechanisms involved in the response in MatSep rats. Wistar Kyoto (WKY) pups were exposed to MatSep 3 h/day from days 2 to 14, while control rats remained with their mothers. ANG II-induced mean arterial pressure (MAP; telemetry) was enhanced in female MatSep rats compared with control female rats but delayed compared with male MatSep rats. Creatinine clearance (Ccr) was reduced in male MatSep rats compared with control rats at baseline and after ANG II infusion. ANG II infusion significantly increased T cells in the renal cortex and greater histological damage in the interstitial arteries of male MatSep rats compared with control male rats. Plasma testosterone was greater and estradiol was lower in male MatSep rats compared with control rats with ANG II infusion. ANG II infusion failed to increase blood pressure in orchidectomized male MatSep and control rats. Female MatSep and control rats had similar Ccr, histological renal analysis, and sex hormones at baseline and after ANG II infusion. These data indicate that during ANG II-induced hypertension, MatSep sensitizes the renal phenotype in male but not female rats. PMID:23174859

    Skin cancer is an increasingly common disease, particularly among young adult women. Sunburn early in life is a risk factor for skin cancer. Few studies have reported on psychosocial correlates of sunburn. The current study consisted of an online survey of undergraduate women from a university in the northeastern part of the USA. A logistic regression demonstrated that young women who reported a history of four or more sunburns were significantly more likely to report fair skin, higher perceived susceptibility to skin cancer, greater perceived benefits of tanning (e.g., appearance enhancement), lower perceived control over skin protection, and more frequent sunscreen use. Sunbathing was not associated with a greater number of sunburns. These results suggest that young women who sunburn more often possess other skin cancer risk factors, are aware of their susceptibility to skin cancer, and try to use sunscreen, but feel limited control over their skin protection behavior and are not less likely to sunbathe than others. Therefore, interventions are needed to assist high risk young women in asserting more control over their sun protection behavior and perhaps improve the effectiveness of the sunscreen or other skin protection methods they do employ.

    Is young people's sexuality becoming more fluid and less tied to steady, stable identity patterns? Are we developing into a society where sexual relationships between individuals of the same sex are no longer reserved for the small minority of gay men and lesbian women? Adherents of so-called queer theory have promulgated such views. Using a population-based sample of young adults (aged 19 to 26, N 2753), we investigated homosexual experiences, desire and identity. We found that levels of prevalence of homosexuality were primarily a function of the criteria we used. Using the most restricted ("narrow") definitions, we found that about one percent of both genders reported "exclusive" homosexual interest and identity. Using the most inclusive criteria, we found that one of ten young men and one of four young women reported having some homosexual experience, interest or identity. Still, the most striking finding involved the substantial gender-specific differences: homoerotic activity and interest are far more interwoven with heterosexual activity for women. There are strong indications that homosexuality is a lot more threatening and potentially in conflict with traditional male gender roles than we find to be the case for women. In other words, while there may be signs of more fluid sexual identity categories, this phenomenon primarily applies to women. PMID:18771114

    Young, novice drivers constitute a disproportionate percentage of fatalities and injuries in road traffic accidents around the world. This study, attempts to identify motivational factors behind risky driving behavior, and examines the role of personality, especially sensation seeking, impulsivity and sensitivity to punishment/reward in predicting negative driving outcomes (accident involvement and traffic offences) among young drivers. Gender and driver's age are additional factors examined in relation to driving outcomes and personality. Adopting the contextual mediated model of traffic accident involvement (Sümer, 2003), the study is based on the theory that personality, age and gender represent distal factors that predict accident involvement indirectly through their relationship with stable tendencies towards aberrant driving behavior. Results from correlations and Structural Equation Modeling using AMOS 6 indicated that direct personality effects on driving outcomes were few, whereas personality had significant correlations with aberrant driving behavior, showing that personality is a distal but important predictor of negative driving outcomes. These high risk traits appear to be at a peak among young male drivers. Thus, personality is important in understanding aggressive and risky driving by young adults and needs to be taken into consideration in designing targeted accident prevention policies.

    This study explored the motivational factors that influence individuals across the stages of change for exercise. The authors compared physically active nonsmokers with physically active smokers in a college student population. Half of regular exercisers identified themselves as smokers. Compared with their nonsmoking peers, young smokers have higher rates of physical and emotional distress. Those participants who exercise and do not smoke are more likely to exhibit intrinsic factors for exercise. Undergraduate psychology students (N = 614) completed an Internet survey on exercise and smoking behavior as well as motivational factors for exercise. Multivariate analyses of variance revealed that intrinsic motivational factors for exercise were significantly higher for the active nonsmokers than for the active smokers. Interventions promoting consistent exercise and smoking abstinence should continue to be directed toward young adults, focusing on fostering intrinsic motivational factors for exercise.

    This study focuses on the experience of young adults employed in the tertiary sector in Brasília. The results show that young people are prepared for work by on-the-job training and nonformal education; schooling is mainly an indicator of trainability. Entry into the labour force reinforces social differences in family background and schooling. The results tend to support the moderate version of classical theory with regard to the nature of school/work relationships. In the context of the conflict paradigm, the data run contrary to both reproductionism and the radical critique of this view. From the comparative standpoint youth is an underprivileged group in the labour market, regardless of sex, socioeconomic status and country of residence. Despite these variations, societies are stratified by age groups.

    Food mishandling in home kitchens likely causes a significant amount of foodborne disease; however, little is known about the food safety hazards lurking in home kitchens. The purposes of this study were to audit the kitchens of young adults with education beyond high school to identify food safety problems and develop recommendations for education efforts. Researchers developed a criterion-referenced home kitchen observation instrument to assess compliance of home food storage and rotation practices (e.g., temperature), sanitation and chemical storage, and general kitchen condition (e.g., infestation) with recommended practices. The instrument contained seven scales: Kitchen Cleanliness (eight items), Appliance Cleanliness (three items), Cleaning Supplies Availability (eight items), Temperatures (Food Thermometer Access & Refrigerator/Freezer Temperatures) (five items), Cold Food Storage (seven items), Dry Food Storage (eight items), and Poisons Storage (two items). Descriptive statistics were conducted to describe the study population, as a whole, and by gender. A total of 154 young adults (mean age, 20.7+/- 1.3 SD) enrolled in a northeastern university participated. Participants scored 70% or higher on Poisons Storage, Dry Food Storage, Kitchen Cleanliness, and Cleaning Supplies Availability scales but less than 60% on the Appliance Cleanliness and Cold Food Storage scales. Performance was lowest on the Temperatures scale. Females scored significantly higher than males on the Kitchen Cleanliness and Cleaning Supply Availability scales. Average refrigerator and freezer temperatures were higher than recommendations. Food safety education targeted at this young adult population needs to evolve into focused messages pertaining to the key food safety violations in this population. PMID:17477272

    Young adults experience problematic responses to loss more often than is commonly recognized. Few empirical studies have examined the contribution of intra- and interpersonal characteristics to grief and depression in bereaved young adults. This study investigated the association of dependency and quality of the relationship with the deceased (i.e., depth and conflict) with complicated grief (CG) and depression. Participants were 157 young adults aged 17–29 who experienced loss of a family member or close friend within the past three years (M = 1.74 years). Participants completed the Inventory of Complicated Grief, Beck Depression Inventory, Depth and Conflict subscales of the Quality of Relationships Inventory, and the Dependency subscale of the Depressive Experiences Questionnaire. Relationships among dependency and interpersonal depth and conflict and CG and depression were examined through analyses of covariance. Sixteen percent of participants met criteria for CG and 34% had mild to severe depression. Dependency and depth were independently related to CG and dependency was related to depression, but the pattern of associations was somewhat different for each outcome. Greater depth was associated with CG, at both high and low levels of dependency. High levels of dependency were related to more depressive symptoms. Interpretation of the findings is limited by the relatively small sample size and cross-sectional design. CG and depression are related but distinct responses to loss. Although dependency is associated with both CG and depression following loss, relationships between the bereaved and deceased that are characterized by high levels of depth are particularly related to the development of CG symptoms.

    Background Emerging evidence from general population studies suggests that lesbian, gay and bisexual (LGB) adults are more likely to experience adverse cardiovascular outcomes relative to heterosexuals. No studies have examined whether sexual orientation disparities exist in biomarkers of early cardiovascular disease risk. Purpose To determine whether sexual orientation disparities in biomarkers of early cardiovascular risk are present among young adults. Methods Data come from Wave IV (2008–2009) of the National Longitudinal Study for Adolescent Health (N=12,451), a prospective nationally representative study of U.S. adolescents followed into young adulthood (mean age: 28.9 years). A total of 520 respondents identified as lesbian, gay, or bisexual. Biomarkers included C-reactive protein, glycosylated hemoglobin, systolic and diastolic blood pressure, and pulse rate. Analyses were conducted in 2012. Results In gender-stratified models adjusted for demographics (age, race/ethnicity); SES (income, education); health behaviors (smoking, regular physical activity, alcohol consumption); and BMI, gay and bisexual men had significant elevations in C-reactive protein, diastolic blood pressure, and pulse rate, compared to heterosexual men. Despite having more risk factors for cardiovascular disease, including smoking, heavy alcohol consumption, and higher BMI, lesbians and bisexual women had lower levels of C-reactive protein than heterosexual women in fully adjusted models. Conclusions Evidence was found for sexual orientation disparities in biomarkers of cardiovascular risk among young adults, particularly in gay and bisexual men. These findings, if confirmed in other studies, suggest that disruptions in core physiologic processes that ultimately confer risk for cardiovascular disease may occur early in the life course for sexual minority men.

    Adult hippocampal neurogenesis, the constitutive generation of new granule cells in the dentate gyrus of the mature brain, is a robust model of neural development and its dysregulation has been implicated in the pathogenesis of psychiatric and neurological disorders. Previous studies in mice have shown that altered expression of Disrupted-In-Schizophrenia 1 (Disc1), the mouse homolog of a risk gene for major psychiatric disorders, results in several distinct morphological phenotypes during neuronal development. Although there are advantages to using rats over mice for neurophysiological studies, genetic manipulations have not been widely utilized in rat models. Here, we used a retroviral-mediated approach to knockdown DISC1 expression in dividing cells in the rat dentate gyrus and characterized the morphological development of adult-born granule neurons. Consistent with earlier findings in mice, we show that DISC1 knockdown in adult-born dentate granule cells in rats resulted in accelerated dendritic growth, soma hypertrophy, ectopic dendrites, and mispositioning of new granule cells due to overextended migration. Our study thus demonstrates that the Disc1 genetic manipulation approach used in prior mouse studies is feasible in rats and that there is a conserved biological function of this gene across species. Extending gene-based studies of adult hippocampal neurogenesis from mice to rats will allow for the development of additional models that may be more amenable to behavioral and in vivo electrophysiological investigations. These models, in turn, can generate additional insight into the systems-level mechanisms of how risk genes for complex psychiatric disorders may impact adult neurogenesis and hippocampal function.

    Four case histories of a representative sample of young adult glue sniffers who had progressed to using illicit drugs or abusing alcohol or both contained several common factors that may have been relevant in the transition. For example, all had suffered parental deprivation or rejection in childhood leading to a state of chronic stress, and all had progressed from sniffing glue to inhaling heroin and thence to "snorting" and injecting heroin. The exact reason for the transition from glue sniffing to misusing other substances was not clear. Nevertheless, although these cases represent only a minority of glue sniffers, the problem of transition may be more common than hitherto supposed. PMID:3917701

    Para testicular rhabdomyosarcoma is a rare malignant tumour, which usually presents as a painless mass in the scrotum or groin. A case of para testicular rhabdomyosarcoma in a 17-year-old male is being reported here who presented with chronic scrotal pain. Paratesticular rhabdomyosarcoma is a rare non germ cell tumour of scrotal sac in children and young adult/teens which can invade testis at presentation. Embryonal variant is the most common type. 40% cases can have metastasis to retroperitoneal lymph node. Diagnosis can be done on high degree of clinical suspicion coupled with biopsy and immunohistochemistry. Multimodality approach of treatment is often beneficial for patients. PMID:26023555

    Using a mobile phone while doing another activity is a common dual-task activity in our daily lives. This study examined the effect of texting on the postural stability of young adults. Twenty college students were asked to perform static and dynamic postural stability tasks. Traditional COP and multivariate multiscale entropy (MMSE) were used to assess the static postural stability and the Star Excursion Balance Test (SEBT) was used to assess the dynamic postural stability. Results showed that (1) texting impaired postural stability, (2) the complexity index did not change much although the task conditions changed, and (3) performing texting is perceived to be more difficult.

    Adolescents and young adults (AYAs) with cancer are at risk for depression due to disruptions in their developmental trajectory, greater physical symptom burden, and increased likelihood of developing aggressive disease. Rates of depression and other psychological disorders are substantially higher in AYAs with cancer when compared with older adults. Psychiatrists caring for these patients must consider the age-appropriate developmental context of these patients along with familial and medical factors that may influence the presentation and treatment of depression. Previous research suggests that psychosocial interventions specifically designed for AYA patients are promising, but studies of psychopharmacology treatments for depression are lacking. There is a pressing need for prospective studies and controlled clinical trials that evaluate the optimal strategies for treating depression in this patient group. PMID:26246791

    Study Design Case report Background Clinical practice guidelines regarding the conservative management of degenerative hip conditions in older adults routinely incorporate therapeutic exercise and manual therapy. However, the application of these recommendations to young, active adults is less clear. The purpose of this case report is to describe the management of a young adult with advanced hip arthrosis using a multi-faceted rehabilitation program. Case Description A 28-year old female with severe left hip degeneration per diagnostic imaging was referred to physical therapy. Reduced hip range of motion and strength, sacroiliac joint asymmetries, and a modified Harris Hip Score of 76 were observed. She was seen for 12 visits over a 3-month period and treated with an individualized program including manual therapy, therapeutic exercise, and neuromuscular re-education. Outcome Substantial improvements were noted in pain, hip range of motion and strength and function (modified Harris Hip Score of 97). In addition, she discontinued the use of anti-inflammatory medications and returned to her prior level of activity. Improvements were maintained at a 3 month follow up, with symptom recurrence managed using a self mobilization technique to the left hip and massage to the left iliopsoas. Discussion Degenerative hip conditions are common among older adults but are relatively rare in the younger population. Although it is likely that this patient will experience a return of her symptoms and functional limitations as her hip disease progresses, the immediate improvements may delay the need for eventual surgical management. These outcomes suggest that physical therapy management should be considered in those with an early onset of degenerative hip disease and are consistent with results previously reported in the older population.

    Though research indicates a complex link between substance use and sexual risk behavior, there is limited research on the association between sexual risk behavior and prescription drug misuse. In light of the alarming increases in prescription drug misuse and the role of demographic characteristics in sexual risk behavior and outcomes, the current study examines demographic differences (gender, sexual identity, age, relationship status, parental class background, and race/ethnicity) in sexual risk behavior, sexual behavior under the influence of prescription drugs, and sexual risk behavior under the influence of prescription drugs in a sample of 402 young adults (18–29) who misuse prescription drugs. Nearly half of the sexually active young adult prescription drug misusers in this sample reported recent sex under the influence of prescription drugs, more than three quarters reported recent sex without a condom, and more than one-third reported recent sex without a condom after using prescription drugs. Zero-inflated Poisson regression models indicated that white race, younger age, higher parental class, and being a heterosexual man were all associated with sexual risk behavior, sex under the influence of prescription drugs, and sexual risk under the influence of prescription drugs. Findings have implications for the targeting of prevention and intervention efforts. PMID:25569204

    Rates of shelter use among homeless youth are low compared to use of other supportive services, yet research on barriers to shelter use has been conducted in limited regions, specifically in West Coast or Midwest cities. Additionally, while studies have generally focused on barriers to shelter use, studies on what might facilitate shelter use are lacking. This study explores barriers and facilitators to shelter use among homeless young adults from a large city in the Southwest region. Focus groups were conducted with a diverse sample of 49 homeless young adults ages 18-24. Drawing on models of health service use, findings were categorized into two domains--attitudinal and access. Themes related to attitudinal barriers include stigma/shame and self-reliance/pride. Attitudinal facilitators include the desire to extricate themselves from street life and turn their lives in a new direction. Access-related themes include barriers such as a lack of shelters and services available to meet the needs of youth, adverse shelter conditions, staff attitudes that are not acceptable to youth, restrictive shelter rules, restrictive definitions of homelessness, and a desire to differentiate themselves from older homeless individuals. Certain characteristics or circumstances (e.g., being pregnant), having supportive others, and shelters' ability to connect them to other services emerged as access facilitators to shelter use. Implications for policymakers, service providers, and future research are discussed. PMID:26246453

    Purpose This is the first study describing the tobacco industry’s objectives developing and publishing lifestyle magazines, linking them to tobacco marketing strategies, and how these magazines may encourage smoking. Methods Analysis of previously secret tobacco industry documents and content analysis of 31 lifestyle magazines to understand the motives behind producing these magazines and the role they played in tobacco marketing strategies. Results Philip Morris (PM) debuted Unlimited in 1996 to nearly 2 million readers and RJ Reynolds (RJR) debuted CML in 1999 targeting young adults with their interests. Both magazines were developed as the tobacco companies faced increased advertising restrictions Unlimited contained few images of smoking, but frequently featured elements of the Marlboro brand identity in both advertising and article content. CML featured more smoking imagery and fewer Camel brand identity elements. Conclusions Lifestyle promotions that lack images of smoking may still promote tobacco use through brand imagery. The tobacco industry still uses the “under the radar” strategies used in development of lifestyle magazines in branded websites. Prohibiting lifestyle advertising including print and electronic media that associate tobacco with recreation, action, pleasures, and risky behaviors or that reinforces tobacco brand identity may be an effective strategy to curb young adult smoking.

    The purpose of the present study was to determine the dietary predictors of visceral adipose tissue (VAT) area in overweight young adults. A total of 109 young adults (fifty males and fifty-nine females) ate ad libitum in a university cafeteria for 14 d. All food and beverages consumed in the cafeteria were measured using observer-recorded weighed plate waste. Food consumption outside the cafeteria (i.e. snacks) was assessed by multiple-pass 24 h recall procedures. VAT was determined using computed tomography. Stepwise regression demonstrated that the best predictor of visceral adiposity in women was total dietary fat (P

    Transition from pediatric to adult healthcare is a well-established challenge for individuals with neurodevelopmental disorders like cerebral palsy. With regard to ethics, some of the key aspects to explore include the following: if and how individuals feel respected during the transition process; if and how their values and preferences are developed and integrated within transition; and if and how young patients are prepared to participate in decision making (to be autonomous) within the transition. We carried out a qualitative study on 14 young adults with cerebral palsy. Some participants reported positive experiences. However, several tension points were identified, including before the transition (eg, transition envisaged with fear and apprehension); during the transition (eg, lack of cooperation or communication between providers in the pediatric and adult healthcare systems); and after the transition (eg, feelings of abandonment). We discuss the clinical influence and ethical significance of better capturing ethical values within the transition process and preparing young individuals to engage in discussions about their health and disease management.

    Few studies address the developmental transition from youth tobacco use uptake to regular adulthood use, especially for noncigarette tobacco products. The current study uses online panel data from the Legacy Young Adult Cohort Study to describe the prevalence of cigarette, other tobacco product, and dual use in a nationally representative sample of young adults aged 18–34 (N = 4,201). Of the 23% of young adults who were current tobacco users, 30% reported dual use. Ever use, first product used, and current use were highest for cigarettes, cigars, little cigars, and hookah. Thirty-two percent of ever tobacco users reported tobacco product initiation after the age of 18 and 39% of regular users reported progressing to regular use during young adulthood. This study highlights the need for improved monitoring of polytobacco use across the life course and developing tailored efforts for young adults to prevent progression and further reduce overall population prevalence.

    Young people are increasingly using social networking sites (SNSs) like MySpace and Facebook to engage with others. The use of SNSs can have both positive and negative effects on the individual; however, few studies identify the types of people who frequent these Internet sites. This study sought to predict young adults' use of SNSs and addictive tendency toward the use of SNSs from their personality characteristics and levels of self-esteem. University students (N = 201), aged 17 to 24 years, reported their use of SNSs and addictive tendencies for SNSs use and completed the NEO Five-Factor Personality Inventory and the Coopersmith Self-Esteem Inventory. Multiple regression analyses revealed that, as a group, the personality and self-esteem factors significantly predicted both level of SNS use and addictive tendency but did not explain a large amount of variance in either outcome measure. The findings indicated that extroverted and unconscientious individuals reported higher levels of both SNS use and addictive tendencies. Future research should attempt to identify which other psychosocial characteristics explain young people's level of use and propensity for addictive tendencies for these popular Internet sites.

    Aging is associated with cognitive decline and alterations in early perceptual processes. Studies in the auditory and visual sensory modalities have shown that the mismatch negativity [or the mismatch response (MMR)], an event-related potential (ERP) elicited by a deviant stimulus in a background of homogenous events, diminishes with aging and cognitive decline. However, the effects of aging on the somatosensory MMR (sMMR) are not known. In the current study, we recorded ERPs to electrical pulses to different fingers of the left hand in a passive oddball experiment in young (22–36 years) and elderly (66–95 years) adults engaged in a visual task. The MMR was found to deviants as compared to standards at two latency ranges: 180–220 ms and 250–290 ms post-stimulus onset. At 180–220 ms, within the young, the MMR was found at medial electrode sites, whereas aged did not show any amplitude difference between the stimulus types at the same latency range. At 250–290 ms, the MMR was evident with attenuated amplitude and narrowed scalp distribution among aged (Fz) compared to young (fronto-centrally and lateral parietal sites). Hence, the results reveal that the somatosensory change detection mechanism is altered in aging. The sMMR can be used as a reliable measure of age-related changes in sensory-cognitive functions.

    We investigated the effects of the introduction of foreign adults on the behavior of young horses. First, we observed the behavior of 1- and 2-year-old domestic horses housed in same-age and same-sex groups (a standard housing system, but different from a natural situation). Then, two same-sex adults were introduced into each experimental group. Observations made before, during and after an introduction indicated that young horses reared in homogeneous groups of young had different behaviors compared to other domestic horses reared under more socially natural conditions. After the introduction of adults, young horses expressed new behaviors, preferential social associations emerged, positive social behavior increased and agonistic interactions decreased. These results have important implications both for understanding the influence that adults may have on the behavior of young horses, and in terms of husbandry, indicating the importance of keeping young horses with adults, although further studies are still necessary.

    Summary Background Pulmonary disease contributes to significant morbidity and mortality in people with ataxia telangiectasia (A-T). To determine the association between age and lung function in children and young adults with A-T and to identify factors associated with decreased lung function, pulmonary function tests were performed in 100 consecutive people with A-T. Methods Children and adults ranging from 6 to 29 years of age and with the diagnosis of A-T were recruited, and underwent pulmonary function tests. Results The mean forced vital capacity % predicted (FVC %) in the population was 56.6 ± 20.0. Males and females between 6 and 10 years of age had similar pulmonary function. Older females were found to have significantly lower FVCs % than both older males (P < 0.02) and younger females (P < 0.001). The use of supplemental gamma globulin was associated with significantly lower FVC %. A modest correlation was found between higher radiation-induced chromosomal breakage and lower FVC % in males. No significant change in FVC % was found in a subset of subjects (n = 25) who underwent pulmonary function testing on two or more occasions over an average of 2 years. Conclusion In children and young adults with A-T, older females and people who required supplemental gamma globulin had significantly lower lung function by cross-sectional analysis. Stable lung function is possible over a 2-year period. Recognition of groups who are at higher risk for lower pulmonary function may help direct care and improve clinical outcomes in people with A-T.

    The purpose of this study was to assess the prevalence of childhood victimization experiences in a sample of young adults in St. Petersburg, Russia. The study sample included 743 students aged 19 to 25 from 15 universities in St. Petersburg, Russia. All of the study participants completed a reliable questionnaire assessing the following types of childhood victimization: conventional crime, child maltreatment, peer victimization, sexual victimization, and witnessing violence. Participation in the study was anonymous. High rates of victimization and exposure to violence were reported by the study participants. The majority of the sample experienced at least one type of victimization during childhood or adolescence, and poly-victimization was reported frequently. The most common type of victimization reported was peer or sibling assault (66.94%), followed by witnessing an assault without weapon (63.91%), personal theft (56.19%), vandalism (56.06%), and emotional bullying (49.99%). Sexual assault by a known adult was reported by 1.45% males and 5.16% of females. This study provides new information on the scope of childhood victimization experiences in Russia. Further research is warranted, including epidemiological research with representative data across the country and studies of the impact of trauma and victimization on mental health and well-being of Russian adults and children.

    Adolescents and young adults (AYA) with advanced or terminal cancer have distinctive medical and psychosocial needs that may not have been adequately provided by either pediatric or adult palliative care services. A discussion group, as part of a larger workshop on AYA with cancer, was held in Toronto on March 11-13, 2010;117:-. Recommendations were as follows: Develop a specific AYA screening tool designed to detect increased anxiety or new symptoms and to initiate discussion about palliative or symptom care; Set Canadian standards for palliative care in AYA patients. These standards should be included in hospital accreditation; Involve the palliative/symptom care team early in the disease trajectory to help manage clinically important symptoms that may not be associated with imminent death; Establish specific AYA multidisciplinary palliative care teams throughout Canada that are flexible and can work in both pediatric and adult facilities, and are able to work in a "virtual" environment to support patients being cared for at home; Improve physical facilities in hospices and hospitals to meet the distinctive needs of terminally ill AYA patients; Enhance support for palliative care at home by: changing legislation to improve Compassionate Care Benefits and developing "virtual palliative care support teams". Adequate provision of AYA palliative care and symptom management services will likely confer notable benefits to AYA patients and their families, and is likely to be cost saving to the tax payer by avoiding prolonged hospitalization and promoting easier return to work for the families and caregivers.

    Abstract Previous studies showed that psychiatric disorders such as major depression, bipolar disorders, and alcohol misuse are associated with an increased risk of ischemic stroke. However, the link between psychiatric disorders and stroke in the young population is rarely investigated. Using the Taiwan National Health Insurance Research Database, 2063 young adults aged between 18 and 45 years with ischemic stroke and 8252 age- and sex-matched controls were enrolled in our study between 1998 and 2011. Participants who had preexisting psychiatric disorders were identified. After adjusting for preexisting physical disorders and demographic data, patients with ischemic stroke had an increased risk of having preexisting psychiatric disorders, including bipolar disorder (odds ratio [OR]: 2.23, 95% confidence interval [CI]: 1.06?4.67), unipolar depression (OR: 2.15, 95% CI: 1.62?2.86), anxiety disorders (OR: 2.63, 95% CI: 1.87?3.69), and alcohol use disorders (OR: 2.86, 95% CI: 1.79?4.57). Young ischemic stroke (age ?30 years) was related to the risk of preexisting unipolar depression (OR: 1.49, 95% CI: 1.05?2.11), anxiety disorders (OR: 1.99, 95% CI: 1.33?2.97), and alcohol use disorders (OR: 2.54, 95% CI: 1.55?4.14); very young stroke (age <30 years) was only associated with the risk of preexisting unipolar depression (OR: 4.15, 95% CI: 1.47?11.72). Patients who had experienced ischemic stroke at age younger than 45 years had a higher risk of having pre-existing bipolar disorder, unipolar depression, anxiety disorders, and alcohol use disorders than those who did not after adjusting for demographic data and stroke-related medical comorbidities.

    Lead is an environmental pollutant with no known beneficial health effects, and environmental or occupational exposure to this metal is known to result in toxicity. It may affect numerous organ systems, including the renal, reticuloendothelial, reproductive, and nervous system. Children and young animals are particularly sensitive to the toxic effects of this metal, being the central nervous system the main target of lead toxicity. Adults seem to be more resistant to lead neurotoxicity, but lead nephrotoxicity is a prominent effect. This study compares lead effects of forebrain, cerebellar, and renal ALAD activity and the reactivation index with DTT obtained from prenatal and lactational lead-exposure of rats and prenatal, lactational, and long-term post lactational lead exposure of rats. 16 refs., 3 tabs.

    This paper describes the types of, and circumstances surrounding, unintentional farm-related fatal injuries involving young and older adults in Australia. Information was obtained from an inspection of coronial files for the period 1989-1992. Around 14% of all farm-related fatalities in Australia during 1989-1992 were of young adults aged 15-24 years and approximately one-quarter were of older adults aged > or = 55 years. Young adults were commonly fatally injured in motor vehicle incidents and in incidents involving firearms. Tractors were the most common agent involved in fatal incidents involving older adults. Intervention measures to prevent fatalities of older adults in agriculture should focus on the safe use of tractors, while for young adults it appears prevention efforts should centre around safe use of firearms and operation of motor vehicles on the farm. Ways to overcome barriers to the use of injury prevention measures in rural Australia should be further explored. PMID:12121411

    There is concern that many young adults (ages 19--29) will remain without health insurance in 2014 despite the Affordable Care Act's reforms, including subsidized private coverage offered in new state marketplaces and expanded Medicaid eligibility. How things turn out will likely depend on outreach efforts and states' decisions on expanding Medicaid. Commonwealth Fund Health Insurance Tracking Survey data from 2011 and 2013 show increasing awareness among young adults of the 2010 requirement that health plans cover children under age 26. Of the estimated 15 million young adults enrolled in a parent's plan in the prior 12 months, 7.8 million would not likely have been eligible to enroll prior to the law. Still, only 27 percent of 19-to-29-year-olds are aware of the marketplaces. Meanwhile, most uninsured young adults living below poverty will not have access to subsidized public or private insurance in states opting out of the Medicaid expansion. PMID:24044138

    The present study was designed to investigate the effects of chronic administration of the arginine analogue L-Name (50 mg/kg body weight), the angiotensin converting enzyme inhibitor, perindopril (2 mg/kg body weight), and perindopril (2 mg/kg) plus L-Name (50 mg/kg) on blood pressure, plasma renin activity, plasma angiotensinogen, and hepatic angiotensinogen mRNA levels in young and adult rats. The drugs were given daily from birth to day 21 to puppies and for 15 days to adults. Analytical procedures were performed on day 21 for the puppies and at 10 weeks for the adults. In puppies, blood pressure did not change with L-Name, it decreased to 45% of control values (P < 0.001) with perindopril, and decreased to 77% of control values (P < 0.05) with perindopril plus L-Name. In adults, blood pressure increased to 129% of control values (P < 0.02) with L-Name, decreased to 80% of control values (P < 0.05) with perindopril, and did not change with perindopril plus L-Name. Compared with controls, plasma renin activity was unchanged in puppies and adults with L-Name, undetectable in puppies and slightly increased in adults with perindopril, undetectable in puppies and slightly decreased in adults with perindopril plus L-Name. With L-Name, angiotensinogen mRNA levels were unchanged in puppies and slightly increased in adults, while plasma angiotensinogen levels were decreased (P < 0.05) in puppies and increased (P < 0.01) in adults; with perindopril, angiotensinogen mRNA levels were unchanged in puppies and slightly decreased in adults, while plasma angiotensinogen levels were undetectable in puppies and decreased (P < 0.05) in adults; with perindopril plus L-Name, angiotensinogen mRNA levels were unchanged in puppies while plasma angiotensinogen levels were undetectable in puppies and decreased (P < 0.01) in adults. This study suggests that during the early postnatal period (1) nitric oxide does not exert a basal vasodilator tone but contributes to the hypotensive state induced by perindopril, (2) angiotensin II is essential to maintain blood pressure, (3) and angiotensinogen mRNA levels are not influenced by nitric oxide or angiotensin II.

    Background: Dental appearance satisfaction is important among young adults because judgment concerning the personal characteristics of individuals is influenced by their dental appearance in the absence of other information. Aim: The aim of the study was to determine the self-evaluated dental appearance satisfaction among young adults. Subjects and Methods: This cross-sectional survey of financial industry prone undergraduates of University of Benin was conducted between July and September, 2010. The self-administered questionnaire which assessed information on demographic characteristics, smoking habit, alcohol use, previous dental visit, dental appearance satisfaction, tooth shape, size, arrangement and strength was the tool of data collection. The data was subjected to descriptive, Chi-square and regression statistics using statistical package for the social sciences version 17.0 (Chicago, IL, USA). (P < 0.05) was considered to be significant. Results: A total of 399 undergraduates which are made up of 179 (44.9%) males and 220 (55.1%) females with mean age of 24.66 (4.20) years participated in this study. Self-evaluated dental appearance satisfaction was expressed by 79.4% (317/399) of the participants. The significant predictors of self-evaluated dental appearance satisfaction were skin color (P = 0.03, odds ratio [OR] =2.57, 95% confidence interval [CI] =1.09-6.09) and perceived tooth strength (P = 0.02, OR = 5.83, 95% CI = 1.40-24.28) among males and alcohol consumption (P = 0.04, OR = 0.45, 95% CI = 0.21-0.95] and perceived size of tooth (P = 0.02, OR = 2.37, 95% CI = 1.15-4.89) among females. The significant predictors of self-evaluated dental appearance satisfaction among the participants were ethnicity (P = 0.04, OR = 0.55, 95% CI = 0.32-0.96), skin color (P = 0.04, OR = 1.74, 95% CI = 1.03-2.93), perceived tooth size (P = 0.03, OR = 1.82, 95% CI = 1.07-3.09) and strength (P = 0.01, OR = 3.42, 95% CI = 1.58-7.41). Conclusion: Ethnicity, tooth arrangement, size and strength need to be given detailed consideration in tooth replacement as they emerged as the significant predictors of self-evaluated dental appearance satisfaction among young adults.

    Accidents caused by scorpion stings, mainly affecting children, are considered an important cause of morbidity and mortality in tropical countries. Clinical studies demonstrate the relevant role of systemic inflammatory events in scorpion envenoming. However, remains poorly understood whether the major lethal component in Tityus serrulatus venom, tityustoxin (TsTX), is able to induce inflammatory responses in the cerebral microcirculation. In this study, we systematically examined leukocyte recruitment into the CNS in response to TsTX injection. Accordingly, developing rats were subjected to a subcutaneous (s.c.) injection of TsTX (0.75mg/kg), and leukocyte recruitment (i.e., 4, 8 and 12h after injection) and TNF-? levels were evaluated. Rats injected with TsTX presented a significant increase in leukocyte rolling and adhesion and higher levels of TNF-? at all time points studied, compared to the control group. Altogether, this work demonstrates the triggering of neuroimmunological mechanisms induced by TsTX injection in young rats. PMID:25545555

    2015-01-01

    Perceptions of family alcohol use have been linked to adolescent alcohol use behaviors, yet there have been no studies that have assessed this relationship in young adults. This study examined perceptions of family alcohol use and their association with participants’ self-reported alcohol use. Participants included 171 undergraduate students (mean age = 21.67, 71.9 percent female, 75.4 percent Caucasian). Participants completed measures assessing quantity and frequency of alcohol use, negative consequences of use, and sibling relationship quality. They also reported their perceptions of alcohol use for siblings and parents during a typical week. Perceptions of siblings’ quantity of weekly alcohol use were significantly associated with participants’ quantity of alcohol use (r = .21, p = .006) and frequency of alcohol use (r = .23, p = .002). Perceptions of parental alcohol use were not related to the participants’ alcohol use patterns. PMID:26339202

    2014-01-01

    We report a case of right optic neuritis caused by Rathke's cleft cyst (RCC) in a young adult. A 15-year-old boy presented with reduced visual acuity in the right eye. He was diagnosed with optic neuritis in the right eye 4 years earlier at other clinics before he was referred to our department. During our one-year examinations, the cause of the reduced vision in his right eye could not be determined conclusively. At the age of 17 years, a RCC was detected by a neurosurgeon who specialized in hypophyseal diseases. He underwent microscopic transsphenoidal resection of the cyst, and his vision recovered to 1.2 and he has had no recurrence for at least 9 months. We suggest that repeated rupturing of the RCC was the cause of the optic neuritis, and a RCC can be successfully treated by surgery even after 3 years of optic neuritis. PMID:25045561

    2014-01-01

    Chronic stress in young adults has become a growing problem within recent decades and many are unable to find cost-effective and accessible treatment for psychological stress in their daily lives. We analyze the market of using a mobile application, Positive Technology, as a solution. Eleven participants, aged between 18 and 24, participated in the exercise. Self-reported stress reduction was measured via an online marketing survey, while physiological measurements were monitored via peripheral devices. Secondary goals assessed the app's ease-of-use, accessibility, and cost. Results indicate that participants enjoyed the availability of the mobile solution and found the app to be fun and easy to learn. Stress levels were reduced in 73% of the participants, with higher effects in females and in participants aged 18-24. We conclude that the mobile platform is an effective means of delivering psychological stress reduction, and could provide an accessible, cost-effective solution. PMID:24875697

    2011-01-01

    In spite of the strong epidemiologic evidence linking migraine and ischemic stroke in young adults, the mechanisms explaining this association remain poorly understood. The observation that stroke occurs more frequently during the interictal phase of migraine prompts to speculation that an indirect relation between the two diseases might exist. In this regard, four major issues might be considered which may be summarized as follows: (1) the migraine-ischemic stroke relation is influenced by specific risk factors such as patent foramen ovale or endothelial dysfunction and more frequent in particular conditions like spontaneous cervical artery dissection; (2) migraine is associated with an increased prevalence of cardiovascular risk factors; (3) the link is caused by migraine-specific drugs; (4) migraine and ischemic vascular events are linked via a genetic component. In the present paper, we will review epidemiological studies, discuss potential mechanisms of migraine-induced stroke and comorbid ischemic stroke, and pose new research questions. PMID:21197470

    2001-01-01

    A young immunocompetent patient was admitted for a febrile illness with malaise, arthralgias, painful leg swelling, and polyserositis. Shortly prior to becoming ill, the patient had traveled to the Northern African desert. The symptoms disappeared during treatment with antibiotics (doxycycline and ceftriaxone) but recurred twice after stopping therapy. A motile gram-negative fusiform rod was isolated from a blood culture taken on the first admission. Analysis of the 16S rRNA gene of the blood culture isolate revealed close similarity with Helicobacter sp. flexispira taxon 8 (99.9% identity), a species that was previously reported as “Flexispira rappini.” This is the first reported case of a recurrent Helicobacter sp. flexispira bacteremia in an adult, immunocompetent patient.

  6. Does gingivitis lead to periodontitis in young adults?

    PubMed

    Prayitno, S W; Addy, M; Wade, W G

    1993-08-21

    It has been assumed that poor oral hygiene predisposes to gingivitis with progression to periodontitis and tooth loss. However, a high prevalence of gingivitis occurs in some populations in which severe periodontitis is rare. To assess whether gingivitis is a reliable predictor of periodontitis, we compared the periodontal health of tea pickers and university students aged between 18 and 30 in Indonesia. Oral hygiene and gingival health was significantly better in students than in tea pickers. However, the prevalence and the severity of chronic periodontitis were similar in the two groups. Our findings suggest that gingivitis is a poor predictor of periodontitis in subjects younger than 30 years. Attempts to prevent periodontitis in young adults through antigingivitis measures such as plaque control may be unsuccessful. PMID:8102432

    Young adults' Ecstasy use trajectories have important implications for individual and population-level consequences of Ecstasy use, but little relevant research has been conducted. This study prospectively examines Ecstasy trajectories in a population-based sample. Data are from the Natural History Study of Drug Use, a retrospective/prospective cohort study conducted in Australia. Population screening identified a probability sample of Ecstasy users aged 19-23 years. Complete data for 30 months of follow-up, comprising 4 time intervals, were available for 297 participants (88.4% of sample). Trajectories were derived using cluster analysis based on recent Ecstasy use at each interval. Trajectory predictors were examined using a generalized ordered logit model and included Ecstasy dependence (World Mental Health Composite International Diagnostic Instrument), psychological distress (Hospital Anxiety Depression Scale), aggression (Young Adult Self Report) and contextual factors (e.g. attendance at electronic/dance music events). Three Ecstasy trajectories were identified (low, intermediate and high use). At its peak, the high-use trajectory involved 1-2 days Ecstasy use per week. Decreasing frequency of use was observed for intermediate and high-use trajectories from 12 months, independently of market factors. Intermediate and high-use trajectory membership was predicted by past Ecstasy consumption (>70 pills) and attendance at electronic/dance music events. High-use trajectory members were unlikely to have used Ecstasy for more than 3 years and tended to report consistently positive subjective effects at baseline. Given the social context and temporal course of Ecstasy use, Ecstasy trajectories might be better understood in terms of instrumental rather than addictive drug use patterns. PMID:23899430

    Purpose We examined the influence of tobacco control program funding, smoke-free air laws, and cigarette prices on young adult smoking outcomes. Methods We use a natural experimental design approach that uses the variation in tobacco control policies across states and over time to understand their influence on tobacco outcomes. We combine individual outcome data with annual state-level policy data to conduct multivariable logistic regression models, controlling for an extensive set of sociodemographic factors. The participants are 18- to 25-year-olds from the 2002–2009 National Surveys on Drug Use and Health. The three main outcomes are past-year smoking initiation, and current and established smoking. A current smoker was one who had smoked on at least 1 day in the past 30 days. An established smoker was one who had smoked 1 or more cigarettes in the past 30 days and smoked at least 100 cigarettes in his or her lifetime. Results Higher levels of tobacco control program funding and greater smoke-free-air law coverage were both associated with declines in current and established smoking (p < .01). Greater coverage of smoke-free air laws was associated with lower past year initiation with marginal significance (p = .058). Higher cigarette prices were not associated with smoking outcomes. Had smoke-free-air law coverage and cumulative tobacco control funding remained at 2002 levels, current and established smoking would have been 5%–7% higher in 2009. Conclusions Smoke-free air laws and state tobacco control programs are effective strategies for curbing young adult smoking. PMID:24268360

    Objectives The present study investigates the usefulness of transiently evoked otoacoustic emissions (TEOAEs) and distortion product OAEs (DPOAEs) in detecting small changes in the hearing of young smoking adults. Methods Otoacoustic emissions were acquired from the ears of 48 young adults (age, 20 to 27 years). The dataset was divided into two groups, smoking (24 persons/48 ears) and nonsmoking (24 persons/48 ears). The level of smoking was relatively small in comparison to previous studies, an average of 3.8 years and 8.7 cigarettes per day. In each ear three OAE measurements were made: TEOAEs, DPOAEs, and spontaneous OAEs (SOAEs). Pure tone audiometry and tympanometry were also conducted. Audiometric thresholds did not differ significantly between the datasets. Half-octave-band values of OAE signal to noise ratios and response levels were used to assess statistical differences. Results Averaged data initially revealed that differences between the two study groups occurred only for TEOAEs at 1 kHz. However when the datasets were divided into ears with and without SOAEs more differences became apparent, both for TEOAEs and DPOAEs. In ears that exhibited SOAEs, both smokers and nonsmokers, there were no statistically significant differences between evoked OAEs; however in all ears without SOAEs, evoked OAEs were higher in the ears of nonsmokers, by as much as 5 dB. These differences were most prominent in the 1-2 kHz range. Conclusion A general decrease in OAE levels was found in the group of smokers. However, in ears which exhibited SOAEs, there was no difference between the evoked OAEs of smokers and nonsmokers. We conclude that smoking had not yet measurably affected the ears of those with acute hearing (i.e., those who exhibit SOAEs). However, in ears without SOAEs, smokers exhibited smaller evoked OAE amplitudes than nonsmokers, even though their audiometric thresholds were within the norm. PMID:26622946

    Purpose Cell phone use has become more widespread over the past decade. Young adults are frequently early adopters of new technologies, including cell phones. Most prior research examining sexting, the act of sending sexually explicit or suggestive images via text message, has focused on the legal or social consequences of this behavior. The current study focused on the public health implications of sexting by examining associations between sexting, substance use, and sexual risk behavior in youth. Methods Young adults (N=763) completed online questionnaires assessing demographics, cell phone use (e.g., texting, sexting), substance use, and sexual risk behaviors. Results Sexting was reported by a substantial minority of participants (44%). Compared to their non-sexting counterparts, participants who engaged in sexting were more likely to report recent substance use and high-risk sexual behaviors, including unprotected sex and sex with multiple partners. Of those who engaged in sexting, a considerable percentage (31.8%) reported having sex with a new partner for the first time after sexting with that person. In multivariate analyses, sexting was associated with high-risk sexual behavior after accounting for demographic factors, total texting behaviors, and substance use. Conclusions Results suggest that sexting is robustly associated with high-risk sexual behavior. Many individuals exchange explicit or provocative photos with long-term sexual partners, but at least some participants in this study were incurring new sexual risks subsequent to sexting. Additional research is needed to understand the contexts in which sexting occurs, motivations for sexting, and relationship of sexting to risk behavior. PMID:23299017

    STUDY OBJECTIVES--To evaluate the impact of an AIDS education programme designed for young adults. DESIGN--A randomised trial with a pre-post test design. SETTING--Participants were drawn from six youth training centres in the city of Nottingham, England. STUDY POPULATION--All trainees aged 16-19 years attending the six centres were included in the sample and centres were randomly allocated to experimental (n = 173) and control (n = 164) groups. The response rate to both questionnaires was high (71%). MEASUREMENTS AND MAIN RESULTS--Data on sexual behaviour, knowledge, and attitudes towards HIV/AIDS were obtained by confidential questionnaire. Two thirds of the sample were sexually active. There were no differences between groups at pre-test and no differences by sex. The experimental group had a significantly higher level of knowledge than the control group post-test. Significantly more experimental than control trainees knew post-test that HIV could be transmitted via anal sex and through broken skin. In addition, twice as many experimental (53%) as control trainees (25%; p < 0.001) were aware that a cure for AIDS was unlikely in the near future. There were no observed effects on sexual behaviour, intentions, or attitudes. CONCLUSIONS--The Streetwize UK educational programme had a significant impact on young adults' knowledge of HIV/AIDS transmission and prevention in the short term. If community based AIDS education is to do more than merely inform, however, resources must be made available for peer led interventions and skills training. PMID:8326271

    Adolescents and young adults use text messaging as their primary mode of communication, thus providing an opportunity to use this mode of communication for mobile health (mHealth) interventions. Youth with diabetes are an important group for these mHealth initiatives, as diabetes management requires an enormous amount of daily effort and this population has difficulty achieving optimal diabetes management. Goal setting and self-efficacy are 2 factors in the management of diabetes. We examined the feasibility of a healthy lifestyle text messaging program targeting self-efficacy and goal setting among adolescents and young adults with diabetes. Participants, ages 16-21, were assigned to either a text messaging group, which received daily motivational messages about nutrition and physical activity, or a control group, which received paper-based information about healthy lifestyle. Both groups set goals for nutrition and physical activity and completed a measure of self-efficacy. Participants' mean age was 18.7 ± 1.6 years old, with diabetes duration of 10.0 ± 4.6 years, and A1c of 8.7 ± 1.7%. The text messaging intervention was rated highly and proved to be acceptable to participants. Self-efficacy, glycemic control, and body mass index did not change over the course of the short, 1-month pilot study. Positive, daily, motivational text messages may be effective in increasing motivation for small goal changes in the areas of nutrition and physical activity. These interventions may be used in the future in youth with diabetes to improve diabetes care. Utilizing more targeted text messages is an area for future research. PMID:25172879

    Previous research suggested that disgust may interfere with healthy sexual functioning by demonstrating that women with sexual pain disorders are characterized by heightened disgust propensity, relatively strong (physiological and subjective) disgust responses when exposed to sexual stimuli, and relatively strong automatic sex-disgust memory associations. To broaden the understanding of the relationship between sex and disgust, Study 1 tested the relationship between trait disgust and sexual functioning in both men (N = 109) and women (N = 187), and showed that specifically for women both relatively high disgust propensity and high sensitivity were related to lower sexual functioning. Study 2 focused on healthy young adults (N = 19 men and N = 24 women), and tested the relationship between trait disgust and automatic sex-disgust associations as well as the predictive value of trait disgust propensity for participants' level of sexual arousal while watching an erotic video. Participants completed a single-target Implicit Association Task and self-report measures of trait disgust propensity, disgust sensitivity, and sexual functioning. Furthermore, genital and subjective sexual arousal was measured, while participants were watching neutral and erotic video clips. Women showed stronger sex-disgust associations and reported higher disgust propensity than men. Overall, indices of trait disgust and sex-disgust associations were not strongly associated with sexual functioning or sexual arousability. Unexpectedly, specifically in men, high levels of trait disgust sensitivity predicted higher levels of genital and subjective sexual arousal. Overall, no strong evidence was found to support the view that, among young adults without sexual difficulties, high trait disgust or relatively strong automatic sex-disgust associations are associated with low sexual functioning and low sexual arousal.

    This study explored the relationship between trajectories of affective self-regulation skills during secondary school and young adult substance use in a large multi-ethnic, urban sample (N = 995). During secondary school, participants completed a measure of cognitive and behavioral skills used to control negative, unpleasant emotions or perceived stress. As young adults, participants reported on the frequency and quantity of their alcohol, cigarette, and marijuana use in a telephone interview. Controlling for demographic variables, self-regulation did not significantly change over adolescence, although there was significant variation in participants’ rates of growth and decline. Lower seventh grade self-regulation and less steep increases in self-regulation were predictive of higher young adult substance use. Male participants had significantly lower initial self-regulation and higher young adult substance use. The results suggest that interventions that build affective self-regulation skills in adolescence may decrease the risk of young adult substance use. PMID:26549966

    We studied the acceptability and feasibility of delivering sun protection messages via electronic media such as short message services (SMS) to people aged 18-40 years. An online survey was conducted using a pre-established panel of volunteers. We compared the characteristics of those who indicated that they would like to be alerted to the UV index, with those who would not, using bivariate logistic regression. Characteristics found to be associated with a desire to receive such advice were entered into a multivariate logistic regression analysis. The median age of the 141 participants was 34 years. Overall, 80% of participants agreed that they would like to receive some form of sun protection advice. Of these, 20% preferred to receive it via SMS and 42% via email. Willingness to receive electronic messages about the UV index was associated with being unsure about whether a suntanned person would look healthy and greater use of sun protection in the past. Careful attention to message framing and timing of message delivery, and focus on the short-term effects of sun exposure such as sunburn and skin ageing should increase the acceptability of such messages to young people. Sun protection messages delivered to young adults via electronic media appear to be feasible and acceptable. PMID:22302765

    Research suggests that being bilingual results in advantages on executive control processes and disadvantages on language tasks relative to monolinguals. Furthermore, the executive function advantage is thought to be larger in older than younger adults, suggesting that bilingualism may buffer against age-related changes in executive function. However, there are potential confounds in some of the previous research, as well as inconsistencies in the literature. The goal of the current investigation was to examine the presence of a bilingual advantage in executive control and a bilingual disadvantage on language tasks in the same sample of young and older monolingual anglophones, monolingual francophones, and French/English bilinguals. Participants completed a series of executive function tasks, including a Stroop task, a Simon task, a sustained attention to response task (SART), the Wisconsin Card Sort Test (WCST), and the digit span subtest of the Wechsler Adult Intelligence Scale, and language tasks, including the Boston Naming Test (BNT), and category and letter fluency. The results do not demonstrate an unequivocal advantage for bilinguals on executive function tasks and raise questions about the reliability, robustness and/or specificity of previous findings. The results also did not demonstrate a disadvantage for bilinguals on language tasks. Rather, they suggest that there may be an influence of the language environment. It is concluded that additional research is required to fully characterize any language group differences in both executive function and language tasks. PMID:25120442

    Objective To examine the robustness of findings regarding state-level adult dependent coverage expansions using detailed outcomes that specify coverage source. Data Sources This study uses the 2001–2009 files of the Current Population Survey's Annual Social and Economic Supplement, covering calendar years 2000–2008, and considers young adults ages 19 through 29. Study Design Difference-in-differences methods were used to estimate the effect of state-level dependent coverage expansions on finely detailed categories of coverage, and falsification tests were used to evaluate the models themselves. Principal Findings Certain published results on state-level parental coverage expansions are flawed, with reported increases driven by changes in spousal coverage. Other published results appear to be in fact driven by parental coverage, but they are not robust to alternative model adjustments. Conclusions This study shows evidence that one study's results on “dependent” coverage are in fact driven by changes in rates of spousal coverage. Results from a second study, though not robust to use of a more conventional DD model, would seem to apply most strongly to individuals at ages at which one would typically have lost parental coverage before reform, consistent with a “passive” effect rather than an “active” effect that enrolls previously uninsured youths.

    Abstract Aim: The aim of this study was to describe the phenomenon of management by way of the ideas by secondary school students and young nurses. Background: Young adults are changing workplaces more than ever before, yet their work expectations and perspectives of management differ to those of previous generations. Methods: The data was collected from upper secondary school students and professionally educated nurses (n = 68), some of whom were immigrants (n = 41). Framed essays were used as a research method and emergent data was analysed using content analysis. Results: According to the results, good management involves systematic management, equality, appreciation of know-how, and the promotion of wellbeing at work. Conclusion: New perspectives on management were drawn from the study, in particular the multiple dimensions of equality in workplace organization and the manager's role in an employee's professional development process. Implication for nursing management: The interactive skills of the manager are emphasized in promoting wellbeing at work. This is especially so in multi-cultural teams, where the manager is expected to be adept at understanding intercultural communication and the values of young employees. PMID:24720464

    The regulation of ketone-body metabolism and the quantitative importance of ketone bodies as lipid precursors in adult rat brain has been studied in vitro. Utilization of ketone bodies and of pyruvate by homogenates of adult rat brain was measured and the distribution of /sup 14/C from (3-/sup 14/C)ketone bodies among the metabolic products was analysed. The rate of ketone-body utilization was maximal in the presence of added Krebs-cycle intermediates and uncouplers of oxidative phosphorylation. The consumption of acetoacetate was faster than that of D-3-hydroxybutyrate, whereas, pyruvate produced twice as much acetyl-CoA as acetoacetate under optimal conditions. Millimolar concentrations of ATP in the presence of uncoupler lowered the consumption of ketone bodies but not of pyruvate. Indirect evidence is presented suggesting that ATP interferes specifically with the mitochondrial uptake of ketone bodies. Interconversion of ketone bodies and the accumulation of acid-soluble intermediates (mainly citrate and glutamate) accounted for the major part of ketone-body utilization, whereas only a small part was oxidized to CO/sub 2/. Ketone bodies were not incorporated into lipids or protein. We conclude that adult rat-brain homogenates use ketone bodies exclusively for oxidative purposes.

    Adult neurogenesis is highly responsive to environmental and physiological factors. The majority of studies to date have examined short-term consequences of enhancing or blocking neurogenesis but long-term changes remain less well understood. Current evidence for age-related declines in neurogenesis warrant further investigation into these long-term changes. In this report we address the hypothesis that early life experience, such as a period of voluntary running in juvenile rats, can alter properties of adult neurogenesis for the remainder of the animal's life. The results indicate that the number of proliferating and differentiating neuronal precursors is not altered in runners beyond the initial weeks post-running, suggesting homeostatic regulation of these processes. However, the rate of neuronal maturation and survival during a 4 week period after cell division was enhanced up to 11 months of age (the end of the study period). This study is the first to show that a transient period of physical activity at a young age promotes changes in neurogenesis that persist over the long-term, which is important for our understanding of the modulation of neurogenesis by exercise with age. Functional integration of adult-born neurons within the hippocampus that resist homeostatic regulation with aging, rather than the absolute number of adult-born neurons, may be an essential feature of adult neurogenesis that promotes the maintenance of neural plasticity in old age.

  4. Trust, negotiation, and communication: young adults’ experiences of primary care services

    PubMed Central

    2013-01-01

    Background Young adulthood is an important transitional period during which there is a higher risk of individuals engaging in behaviours which could have a lasting impact on their health. Research has shown that young adults are the lowest responders to surveys about healthcare experiences and are also the least satisfied with the care they receive. However, the factors contributing to this reduced satisfaction are not clear. The focus of our research was to explore the needs and experiences of young adults around healthcare services with an aim of finding out possible reasons for lower satisfaction. Methods Twenty young adults were interviewed at GP surgeries and at a local young adult advice agency, exploring their experiences and use of primary care services. Interviews were analysed using thematic analysis. Results The use of primary care services varied amongst the young adult interviewees. Many interviewees reported positive experiences; those who did not linked their negative experiences to difficulties in negotiating their care with the health care system, and reported issues with trust, and communication difficulties. Most of the interviewees were unaware of the use of patient surveys to inform healthcare planning and delivery and were not inclined to take part, mainly because of the length of surveys and lack of interest in the topic area. Conclusions In order to effectively address the health needs of young adults, young adults need to be educated about their rights as patients, and how to most efficiently use primary care services. GPs should be alert to effective means of approaching and handling the healthcare needs of young adults. A flexible, varied approach is needed to gathering high quality data from this group in order to provide services with information on the changes necessary for making primary care services more accessible for young adults.

    Purpose The purpose of the study was to examine the characteristics of American young adults with increased risk for type 2 diabetes (T2D). Methods Participants ages 18 to 29, overweight/obese, and sedentary were recruited from the metro Atlanta area in the United States. Variables included demographics, anthropometric and clinical variables, and physical activity. Of 107 participants, 3 participants had undiagnosed diabetes and 1 participant did not complete the modifiable activity questionnaire. Thus, 103 young adults remained for the final data analysis. Results Most participants were females and African Americans. About 30% of participants had prediabetes, either impaired fasting glucose, an A1C of 5.7% to 6.4%, or both. Overall, prediabetes young adults were heavier and did less physical activity than Diabetes Prevention Program (DPP) trial participants. In addition, these young adults had a higher prevalence of parental T2D history and lower level of physical activity compared to young adults with normoglycemia. Conclusions Physical activity and parent T2D history are key risk factors for identifying young adults with prediabetes. Multilevel strategies are necessary to raise awareness of diabetes risk and to prevent T2D in young adults. PMID:23640300

    This study investigated the relationship between acculturation and psychological problems in Turkish and Moroccan young adults living in the Netherlands. A sample of 131 healthy young adults aged between 18 and 24 years old, with a Turkish or Moroccan background was recruited using snowball sampling. Data on acculturation, internalizing and externalizing problems, beliefs about psychological problems, attributions of psychological problems and barriers to care were collected and analyzed using Latent Class Analysis and multinomial logistic regression. Three acculturation classes were identified in moderately to highly educated, healthy Turkish or Moroccan young adults: integration, separation and diffusion. None of the participants in the sample were marginalized or assimilated. Young adults reporting diffuse acculturation reported more internalizing and externalizing problems than those who were integrated or separated. Separated young adults reported experiencing more practical barriers to care than integrated young adults. Further research with a larger sample, including young adult migrants using mental health services, is required to improve our understanding of acculturation, psychological problems and barriers to care in this population. Including experiences of discrimination in the model might improve our understanding of the relationship between different forms of acculturation and psychological problems. PMID:25845438

    2013-01-01

    Considering the prevalence and consequences of health-risking sexual behaviors (HRSBs) and STDs among young adults, their prevention is a public health priority. Emerging etiological and prevention outcome literatures suggested study of the long-term effects of universal family-focused interventions on young adult HRSBs and STDs. Although earlier studies have demonstrated intervention impact on adolescent substance misuse, no study has examined universal family-focused intervention effects on young adult HRSBs and STDs via reductions in adolescent misuse. Sixth grade students and their families enrolled in 33 rural Midwestern schools were randomly assigned to experimental conditions. Self-report questionnaires provided data at pretest (Ns=238, 221, and 208 for the Iowa Strengthening Families Program [ISFP], Preparing for the Drug Free Years [PDFY], and control groups, respectively), with seven data points through young adulthood (age 21). In latent growth modeling, three young adult HRSB measures (number of sexual partners, condom use, substance use with sex) and lifetime STDs were specified as distal outcomes mediated by adolescent substance initiation growth factors (average level and rate of change). Results showed that the models fit the data and, except for condom use, there were significant indirect effects, with a higher frequency of significant findings for ISFP. The model additions of direct intervention effects on young adult outcomes generally were not supported, consistent with a model positing that long-term intervention effects on young adult HRSBs and STDs outcomes are indirect. As an indication of the practical significance of long-term effects, analyses revealed relative reduction rates ranging from 6 % to 46 % for significant outcomes. PMID:23408278

    Purpose This study examined associations between frequency of self-weighing and healthy weight control behaviors, unhealthy weight control behaviors, muscle enhancing behaviors (e.g. steroid use, protein powders), and psychological well-being (i.e., self-esteem, depression, body satisfaction) in a community sample of young adults. Methods Data were drawn from Project EAT-III (Eating and Activity in Teens and Young Adults), the third wave of a population-based study. Participants included young adults (n=2,287, mean age=25.3) from the Minneapolis/St. Paul metropolitan area. Results Self-weighing a few times per week or more frequently was reported by 18% of young adult women and 12% of young adult men. Linear regression models, adjusted for body mass index and demographic characteristics, indicated that in both women and men more frequent self-weighing was associated with a higher prevalence of dieting, both healthy and unhealthy weight control behaviors, and muscle-enhancing behaviors. Additionally, young women who reported more frequent self-weighing were more likely to report binge eating. More frequent self-weighing was also associated with more depressive symptoms and lower self-esteem in women and lower body satisfaction in young men. Conclusions More frequent self-weighing is associated with healthy and unhealthy weight control practices, use of muscle enhancing behaviors, and poorer psychological well-being in young adults. Young adults engaging in self-weighing behaviors should be screened for these health indicators and counseled as appropriate. Prior to recommending self-weighing as a weight-monitoring tool, health care providers should ensure that young adults are not at risk for an unhealthy preoccupation with body weight or shape.

    Background Despite the high prevalence of mental health concerns, few young adults access treatment. While much research has focused on understanding the barriers to service access, few studies have explored unbiased accounts of the experiences of young adults with mental health concerns. It is through hearing these experiences and gaining an in-depth understanding of what is being said by young adults that improvements can be made to interventions focused on increasing access to care. Objective To move beyond past research by using an innovative qualitative research method of analyzing the blogs of young adults (18–25 years of age) with mental health concerns to understand their experiences. Methods We used an enhanced Internet search vehicle, DEVONagent, to extract Internet blogs using primary keywords related to mental health. Blogs (N = 8) were selected based on age of authors (18–25 years), gender, relevance to mental health, and recency of the entries. Blogs excerpts were analyzed using a combination of grounded theory and consensual qualitative research methods. Results Two core categories emerged from the qualitative analysis of the bloggers accounts: I am powerless (intrapersonal) and I am utterly alone (interpersonal). Overall, the young adult bloggers expressed significant feelings of powerlessness as a result of their mental health concerns and simultaneously felt a profound sense of loneliness, alienation, and lack of connection with others. Conclusions The present study suggests that one reason young adults do not seek care might be that they view the mental health system negatively and feel disconnected from these services. To decrease young adults’ sense of powerlessness and isolation, efforts should focus on creating and developing resources and services that allow young adults to feel connected and empowered. Through an understanding of the experiences of young adults with mental health problems, and their experiences of and attitudes toward receiving care, we provide some recommendations for improving receptivity and knowledge of mental health care services.

    Background Previous studies involving adults suggest that Post Traumatic Stress Disorder (PTSD) increases the prevalence of cannabis use disorders (CUD)(cannabis dependence and cannabis abuse). However, little work with PTSD and CUD has been conducted involving adolescents, despite the fact that CUD typically have their onset during adolescence. This study addresses the effect of PTSD on CUD among teenagers transitioning to young adulthood. Method The subjects in this ongoing study were the offspring of adult men with a lifetime history of a Substance Use Disorder (SUD) (SUD + probands, N=343) versus those with no lifetime history of a SUD (SUD ? probands, N=350). The participants were initially recruited when the index sons of these fathers were 10-12 years of age, and subsequent assessments were conducted at age 12-14, 16, 19, 22, and 25. Other variable examined were an index of behavioral undercontrol associated with future risk for developing SUD, known as the Transmissible Liability Index, or TLI, and affiliation with deviant peers. Multivariate logistic regression and path analyses were conducted. Results Of these 693 subjects, 31 subjects were diagnosed with PTSD, and 161 were diagnosed with a CUD. The CUD subjects included 136 male participants and 25 female participants, including 103 (64%) Caucasian participants and 58 (36%) participants of other races. Logistic regression demonstrated that the development of a CUD was associated with deviance of peers (Wald=63.4, p=0.000), the TLI (Wald=28.8, p=0.000), African American race (Wald=14.2, p=0.000), PTSD (Wald=12.7, p=0.000), male gender (Wald=12.0, p=0.001), household SES (Wald=9.2, p=0.002), and being an offspring of a SUD+ proband (Wald=6.9, 0.009). Path analyses demonstrated that PTSD is directly associated with the presence of a CUD and with peer deviance, that higher peer deviance is associated with the presence of a CUD, and that PTSD mediated the association between peer deviance and CUD. Conclusions These findings suggest that PTSD contributes to the etiology of CUD among teenagers making the transition to young adulthood beyond the effects of deviant peers, the TLI (Transmissible Liability Index, a measure of risk for SUD), and demographic factors.

    This study explored the roles and psychological experiences identified as defining adult moments using mixed methods with a racially, ethnically, and socioeconomically diverse sample of young adults both enrolled and not enrolled in college (N = 726; ages 18-35). First, we evaluated results from a single survey item that asked participants to rate how adult they feel. Consistent with previous research, the majority of participants (56.9%) reported feeling “somewhat like an adult,” and older participants had significantly higher subjective adulthood, controlling for other demographic variables. Next, we analyzed responses from an open-ended question asking participants to describe instances in which they felt like an adult. Responses covered both traditional roles (e.g., marriage, childbearing; 36.1%) and nontraditional social roles and experiences (e.g., moving out of parent’s home, cohabitation; 55.6%). Although we found no differences by age and college status in the likelihood of citing a traditional or nontraditional role, participants who had achieved more traditional roles were more likely to cite them in their responses. In addition, responses were coded for psychological experiences, including responsibility for self (19.0%), responsibility for others (15.3%), self-regulation (31.1%), and reflected appraisals (5.1%). Older participants were significantly more likely to include self-regulation and reflected appraisals, whereas younger participants were more likely to include responsibility for self. College students were more likely than noncollege students to include self-regulation and reflected appraisals. Implications for research and practice are discussed. PMID:23554545

    Young adults (YA) are underrepresented in behavioral weight loss programs and achieve poorer outcomes than older adults (OA). There has been a call to develop programs specifically targeting this age group. This study examined the performance of YA enrolled in a low intensity, team-based weight loss campaign and compared their outcomes to OA to determine the utility of such an approach for weight loss in this population. Shape Up Rhode Island 2009 was a 12-week online team-based weight loss and exercise competition (N=6795, 81% female, 94% White, age=44.7±11.2, BMI=29.4±5.9). YA was defined as 18–35 years and OA as >35 years; YA and OA were compared on enrollment, retention, weight loss and change in steps. A total of 1562 YA enrolled and 715 completed the program. Fewer YA completed compared with OA (46% vs. 62%, p<.001). However, among completers, YA achieved greater percent weight loss (?4.5±4.0% vs. ?3.8±3.2%) and greater daily step change (+1578.2±3877.2 vs. +1342.2±3645.7) than OA (p’s<.001). Further, more YA completers achieved a ?5% weight loss (40% vs. 29%, p<.001). Findings were consistent in the overweight/obese subsample, and using ?25 years of age as the cut off for YA. Weight losses among YA in this low-intensity weight loss campaign were quite promising, with over 700 YA completing the program and on average achieving a 4.5% weight loss. Indeed, the potential public health impact of such an approach is substantial; future efforts to develop programs for this age group may benefit from using a low intensity, team-based approach.

    The aims of the study were (1) to investigate gender differences in pornography consumption among Danish adults aged 18-30 and (2) to examine gender differences in situational, interpersonal, and behavioral characteristics of pornography consumption. A national survey study was conducted using a representative sample of 688 young heterosexual Danish adult men and women. The study found large gender differences in prevalence rates of pornography consumption and consumption patterns. Compared to women, men were exposed to pornography at a younger age, consumed more pornography as measured by time and frequency, and used pornography more often during sexual activity on their own. Gender differences in the interpersonal context of use were also evident, with women using pornography more often with a regular sexual partner than men. In turn, men were found to use pornography more often on their own or with friends (non-sexual partners) than women. For both men and women, the usual place of use was home and no significant gender difference was found in this regard. Men and women were found to vary in their preferences in pornographic materials, with men both preferring a wider range of hardcore pornography and less softcore pornography than women. Gender differences in sexual behavioral factors were limited to masturbation patterns with men masturbating more than women. Male gender, higher frequency of masturbation, lower age at first exposure, and younger age were found to account for 48.8% of the total variance of pornography consumption. The results were discussed in relation to the sociocultural environment and evolutionary theory. It is argued that gender differences in social acceptability, adherence to gender stereotypes, traditions of gender sexuality, gender norms, and mating strategies are key factors in understanding gender differences in pornography consumption.

    Little is known about the relationship between relative body weight and transition from experimentation to regular smoking in young adult women. In the current study, data from 2494 participants in wave 4 of the Missouri Adolescent Female Twin Study (aged 18-29years) who reported ever smoking a cigarette were analyzed using logistic regression. Body mass index (BMI) at time of interview was categorized according to CDC adult guidelines, and regular smoking was defined as having ever smoked 100 or more cigarettes and having smoked at least once a week for two months in a row. Since the OR's for the overweight and obese groups did not differ significantly from one another in any model tested, these groups were combined. Forty-five percent of women who had ever smoked had become regular smokers. Testing of interactions between potential covariates and levels of the categorical BMI variable revealed a significant interaction between overweight/obesity and childhood sexual abuse (CSA; p<0.001) associated with regular smoking. Among women reporting CSA, the association between overweight/obesity and having become a regular smoker was negative (n=374; OR=0.48, 95% CI: 0.28-0.81). Both underweight and overweight/obesity were positively associated with transition to regular smoking among women who did not report CSA (n=2076; OR=1.57, 95% CI: 1.05-2.35 and OR=1.73, 95% CI: 1.35-2.20, respectively). These results suggest that experiencing CSA alters the association between BMI and regular smoking in women who have experimented with cigarettes. PMID:20634004

    This study examined the utilization of the Internet by young adults as a source of information for the non-medical use of prescription drugs. Collected during 2008 and 2009, the data presented here comes from semi-structured interviews (N=62) conducted in a northwestern city of the United States through support from the National Institute on Drug Abuse. Previous studies have characterized young adults as particularly vulnerable to online prescription drug information which analysts portray as having a significant, invariably detrimental, impact on youth drug use behaviors. The results presented here suggest that young adults are more skeptical and information-savvy than many substance abuse analysts acknowledge. PMID:21599506

    Given the limited research on young adults' reactions to 12-step programs, the purpose of this study was to explore young adults' views of Alcoholics Anonymous and Narcotics Anonymous. Qualitative interviews with 26 young adults who had attended Alcoholics Anonymous or Narcotics Anonymous were conducted. Most participants viewed 12-step programs favorably, reporting that the programs provided hope and emotional support. Participants who rejected the programs often refused to accept the concepts of powerlessness and a higher power. Many participants who rejected Alcoholics Anonymous and Narcotics Anonymous were unaware of some of the key tenets of the programs, suggesting that 12-step facilitation would benefit this population.

    Two experiments explored whether the higher vulnerability to false memories in the DRM (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995) paradigm in older compared to young adults reflects a deficit in source monitoring. In both experiments, adding together the number of falsely recalled critical lures and the number of critical lures produced on a post-recall test asking participants to report items that they had thought of but did not recall, indicated that the critical lures were activated during the experiment equally often in young and older adults. However, older adults were more likely than young adults to say that they had actually heard the lures. When strongly encouraged to examine the origin of memories (Experiment 2), the warning substantially reduced false recall in young but not older adults. These results are consistent with the idea that older adults have more difficulty later identifying the source of information that was activated as a consequence of intact semantic activation processes.

    The repeated-dose liver micronucleus (RDLMN) assay using young adult rats has the potential to detect hepatocarcinogens. We conducted a collaborative study to assess the performance of this assay and to evaluate the possibility of integrating it into general toxicological studies. Twenty-four testing laboratories belonging to the Mammalian Mutagenicity Study Group, a subgroup of the Japanese Environmental Mutagen Society, participated in this trial. Twenty-two model chemicals, including some hepatocarcinogens, were tested in 14- and/or 28-day RDLMN assays. As a result, 14 out of the 16 hepatocarcinogens were positive, including 9 genotoxic hepatocarcinogens, which were reported negative in the bone marrow/peripheral blood micronucleus (MN) assay by a single treatment. These outcomes show the high sensitivity of the RDLMN assay to hepatocarcinogens. Regarding the specificity, 4 out of the 6 non-liver targeted genotoxic carcinogens gave negative responses. This shows the high organ specificity of the RDLMN assay. In addition to the RDLMN assay, we simultaneously conducted gastrointestinal tract MN assays using 6 of the above carcinogens as an optional trial of the collaborative study. The MN assay using the glandular stomach, which is the first contact site of the test chemical when administered by oral gavage, was able to detect chromosomal aberrations with 3 test chemicals including a stomach-targeted carcinogen. The treatment regime was the 14- and/or 28-day repeated-dose, and the regime is sufficiently promising to incorporate these methods into repeated-dose toxicological studies. The outcomes of our collaborative study indicated that the new techniques to detect chromosomal aberrations in vivo in several tissues worked successfully. PMID:25892619

    There has been relatively little longitudinal controlled investigation of the effects of yoga on general physical fitness, despite the widespread participation in this form of exercise. The purpose of this exploratory study was to examine the effect of short-term Bikram yoga training on general physical fitness. Young healthy adults were randomized to yoga training (N = 10, 29 ± 6 years, 24 sessions in 8 weeks) or a control group (N = 11, 26 ± 7 years). Each yoga training session consisted of 90-minute standardized supervised postures performed in a heated and humidified studio. Isometric deadlift strength, handgrip strength, lower back/hamstring and shoulder flexibility, resting heart rate and blood pressure, maximal oxygen consumption (treadmill), and lean and fat mass (dual-energy x-ray absorptiometry) were measured before and after training. Yoga subjects exhibited increased deadlift strength, substantially increased lower back/hamstring flexibility, increased shoulder flexibility, and modestly decreased body fat compared with control group. There were no changes in handgrip strength, cardiovascular measures, or maximal aerobic fitness. In summary, this short-term yoga training protocol produced beneficial changes in musculoskeletal fitness that were specific to the training stimulus. PMID:22592178

    Good eating habit is an essential part of a healthy lifestyle. It helps prevent civilisation diseases. The BMI and eating plan analysis are useful in individual's nutritional assessment. The aim of the study was to assess nutritional status and eating habits in young adults. An average BMI was 23.63 kg/ m2 in the interviewed men, and 20.6 kg/m2 in women. Caloric value of the daily eating plans was average: in men 2943 kcal, in women 2272 kcal. Four people were on diets, but none of BMI over 25 kg/m2. There were no people suffering from food allergies nor gastrointestinal diseases. Only one male did sports (weight-lifting) regularly. The majority of the students ate at lunchtime at the university cafeteria or prepared meals themselves. The eating plans varied very much: the majority was based on the Eating Guide Pyramid and consisted of three balanced meals during the day-time; there were also single cases where students stuck to eating high-calorie meals at night-time mostly.

    The objective of the study described in this article was to ascertain the food safety knowledge and practices of undergraduate students attending a major American university. The study participants were undergraduate college students (mean age 18.9 +/- 1.14 SD) enrolled in a required health course. The students were invited to take a validated food safety knowledge questionnaire as part of a health risk behavior online survey. The 786 respondents indicated their food is most often prepared at on-campus dining facilities and the majority of the students (72%) felt they were "unlikely or "very unlikely" at risk of foodborne disease. The mean food safety knowledge score of the participants was 10.23 (43%) +/- 4.13 SD (25%-60%), indicating the study population overall has poor knowledge of safe food practices. As a result, food safety educational initiatives and awareness campaigns should be developed to better inform young adults about safe food handling practices and habits. PMID:26058218

    Dietary antioxidants may protect against poor ventilatory function. We assessed the relation between ventilatory function and antioxidant components of diet in young Chileans. Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and the ratio FEV1/FVC were measured in 1232 adults aged 22–28 years, using a Vitalograph device. Dietary intake was ascertained with a food frequency questionnaire (FFQ) designed for this study, from which nutrient and flavonoid intakes were estimated. Dietary patterns were derived with Principal Component Analysis (PCA). After controlling for potential confounders, dietary intake of total catechins was positively associated with FVC (Regression coefficient (RC) of highest vs. lowest quintile of intake 0.07; 95% CI 0.01 to 0.15; p per trend 0.006). Total fruit intake was related to FVC (RC of highest vs. lowest quintile 0.08; 95% CI 0.003 to 0.15; p per trend 0.02). Intake of omega 3 fatty acids was associated with a higher FEV1 (RC for highest vs. lowest quintile 0.08; 95% CI 0.01 to 0.15 L; p per trend 0.02) and with FVC 0.08 (RC in highest vs. lowest quintile of intake 0.08, 95% CI 0.001 to 0.16; p per trend 0.04). Our results show that fresh fruits, flavonoids, and omega 3 fatty acids may contribute to maintain ventilatory function. PMID:25884660

    Impulsivity is a heritable, multifaceted construct with clinically relevant links to multiple psychopathologies. We assessed impulsivity in young adult (N~2100) participants in a longitudinal study, using self-report questionnaires and computer-based behavioral tasks. Analysis was restricted to the subset (N=426) who underwent genotyping. Multivariate association between impulsivity measures and single-nucleotide polymorphism data was implemented using parallel independent component analysis (Para-ICA). Pathways associated with multiple genes in components that correlated significantly with impulsivity phenotypes were then identified using a pathway enrichment analysis. Para-ICA revealed two significantly correlated genotype–phenotype component pairs. One impulsivity component included the reward responsiveness subscale and behavioral inhibition scale of the Behavioral-Inhibition System/Behavioral-Activation System scale, and the second impulsivity component included the non-planning subscale of the Barratt Impulsiveness Scale and the Experiential Discounting Task. Pathway analysis identified processes related to neurogenesis, nervous system signal generation/amplification, neurotransmission and immune response. We identified various genes and gene regulatory pathways associated with empirically derived impulsivity components. Our study suggests that gene networks implicated previously in brain development, neurotransmission and immune response are related to impulsive tendencies and behaviors. PMID:25268255

    This study is part of a broader project aimed at developing cognitive and neurocognitive profiles of adolescent and young adult readers whose educational and occupational prospects are constrained by their limited literacy skills. We explore the relationships among reading-related abilities in participants ages 16 to 24 years spanning a wide range of reading ability. Two specific questions are addressed: (a) Does the simple view of reading capture all nonrandom variation in reading comprehension? (b) Does orally assessed vocabulary knowledge account for variance in reading comprehension, as predicted by the lexical quality hypothesis? A comprehensive battery of cognitive and educational tests was employed to assess phonological awareness, decoding, verbal working memory, listening comprehension, reading comprehension, word knowledge, and experience with print. In this heterogeneous sample, decoding ability clearly played an important role in reading comprehension. The simple view of reading gave a reasonable fit to the data, although it did not capture all of the reliable variance in reading comprehension as predicted. Orally assessed vocabulary knowledge captured unique variance in reading comprehension even after listening comprehension and decoding skill were accounted for. We explore how a specific connectionist model of lexical representation and lexical access can account for these findings. PMID:17518215

    Symptoms of narcolepsy tend to arise during adolescence or young adulthood, a formative time in human development during which people are usually completing their education and launching a career. Little is known about the impact of narcolepsy on the social aspects of health-related quality of life in young adults. The purpose of this study was to examine relationships between health-related stigma, mood (anxiety and depression) and daytime functioning in young adults with narcolepsy compared to those without narcolepsy. Young adults (age 18–35) with narcolepsy (N = 122) and without narcolepsy (N = 93) were mailed a packet that included questionnaires and a self-addressed postage paid envelope. The questionnaire included demographic information and a composite of instruments including the SF 36, Functional Outcomes of Sleep Questionnaire (FOSQ), Fife Stigma Scale (FSS), Epworth Sleepiness Scale (ESS) and Hospital Anxiety and Depression Scale (HADS). Variable associations were assessed using descriptive statistics, ANOVA, Mann-Whitney U Test, correlations, stepwise multiple regression and path analysis. Young adults with narcolepsy perceived significantly more stigma and lower mood and health-related quality of life than young adults without narcolepsy (p<0.01). Health-related stigma was directly and indirectly associated with lower functioning through depressed mood. Fifty-two percent of the variance in functioning was explained by the final model in the young adults with narcolepsy. Health-related stigma in young adults with narcolepsy is at a level consistent with other chronic medical illnesses. Health-related stigma may be an important determinant of functioning in young adults with narcolepsy. Future work is indicated toward further characterizing stigma and developing interventions that address various domains of stigma in people with narcolepsy. PMID:25898361

    2010-01-01

    Background This study represents the first attempt to perform a profiling analysis of the intergenerational differences in the microRNAs (miRNAs) of primary cutaneous melanocytic neoplasms in young adult and older age groups. The data emphasize the importance of these master regulators in the transcriptional machinery of melanocytic neoplasms and suggest that differential levels of expressions of these miRs may contribute to differences in phenotypic and pathologic presentation of melanocytic neoplasms at different ages. Methods An exploratory miRNA analysis of 666 miRs by low density microRNA arrays was conducted on formalin fixed and paraffin embedded tissues (FFPE) from 10 older adults and 10 young adults including conventional melanoma and melanocytic neoplasms of uncertain biological significance. Age-matched benign melanocytic nevi were used as controls. Results Primary melanoma in patients greater than 60 years old was characterized by the increased expression of miRs regulating TLR-MyD88-NF-kappaB pathway (hsa-miR-199a), RAS/RAB22A pathway (hsa-miR-204); growth differentiation and migration (hsa-miR337), epithelial mesenchymal transition (EMT) (let-7b, hsa-miR-10b/10b*), invasion and metastasis (hsa-miR-10b/10b*), hsa-miR-30a/e*, hsa-miR-29c*; cellular matrix components (hsa-miR-29c*); invasion-cytokinesis (hsa-miR-99b*) compared to melanoma of younger patients. MiR-211 was dramatically downregulated compared to nevi controls, decreased with increasing age and was among the miRs linked to metastatic processes. Melanoma in young adult patients had increased expression of hsa-miR-449a and decreased expression of hsa-miR-146b, hsa-miR-214*. MiR-30a* in clinical stages I-II adult and pediatric melanoma could predict classification of melanoma tissue in the two extremes of age groups. Although the number of cases is small, positive lymph node status in the two age groups was characterized by the statistically significant expression of hsa-miR-30a* and hsa-miR-204 (F-test, p-value < 0.001). Conclusions Our findings, although preliminary, support the notion that the differential biology of melanoma at the extremes of age is driven, in part, by deregulation of microRNA expression and by fine tuning of miRs that are already known to regulate cell cycle, inflammation, Epithelial-Mesenchymal Transition (EMT)/stroma and more specifically genes known to be altered in melanoma. Our analysis reveals that miR expression differences create unique patterns of frequently affected biological processes that clearly distinguish old age from young age melanomas. This is a novel characterization of the miRnomes of melanocytic neoplasms at two extremes of age and identifies potential diagnostic and clinico-pathologic biomarkers that may serve as novel miR-based targeted modalities in melanoma diagnosis and treatment.

    Although influenza vaccination is recommended for all adults annually, the incidence of vaccine failure, defined as weak or absent increase in neutralizing antibody titers, is increased in the elderly compared to young adults. The T follicular helper subset of CD4 T cells (Tfh) provides B cell help in germinal centers and is necessary for class-switched antibody responses. Previous studies suggested a role for circulating T follicular helper cells (cTfh) following influenza vaccination in adults, but cTfh have not been studied in elderly adults where weak vaccine responses are often observed. Here, we studied cTfh expressing CXCR5 and Programmed Death 1 (PD-1). cTfh from elderly adults were present at reduced frequency, had decreased in vitro B cell help ability, and greater expression of inducible costimulator (ICOS) compared to young adults. At seven days after inactivated influenza vaccination, cTfh correlated with influenza vaccine-specific IgM and IgG responses in young adults but not in elderly adults. In sum, we have identified aging-related changes in cTfh that correlated with reduced influenza vaccine responses. Future rational vaccine design efforts should incorporate Tfh measurement as an immune correlate of protection, particularly in the setting of aging. PMID:25172499

    Background Twelve-Step Facilitation (TSF) interventions designed to enhance rates of engagement with 12-step mutual help organizations (MHOs) have shown efficacy among adults, but research provides little guidance on how to adapt TSF strategies for young people. Methods To inform TSF strategies for youth, this study used qualitative methods to investigate the self-reported experiences of 12-step participation, and reasons for non-attendance and discontinuation among young adults (18-24 yrs; N=302). Responses to open-ended questions following residential treatment were coded into rationally-derived domains. Results Young adults reported that cohesiveness, belonging, and instillation of hope were the most helpful aspects of attending 12-step groups; meeting structure and having to motivate oneself to attend meetings were the most common aspects young adults liked least; logistical barriers and low recovery motivation and interest were the most common reasons for discontinued attendance; and perceptions that one did not have a problem or needed treatment were cited most often as reasons for never attending. Conclusions Findings may inform and enhance strategies intended to engage young people with community-based recovery focused 12-step MHOs and ultimately improve recovery outcomes. PMID:25102256

    Increasing evidence suggests that alterations in early nutrition programme physiological changes in adulthood. In the present study, we determined the effects of undernutrition during gestation and lactation on the programming of thyroid function in adult rat offspring. Perinatal undernutrition was achieved by a 40% food restriction in female Wistar rats from the mating day to weaning. On postpartum day 21, the offspring of the control and food-restricted dams were weaned and given free access to a commercial diet until adulthood. The results showed that undernourished rats exhibited decreased 3,5,3'-triiodothyronine (T3) levels but had normal thyroxine (T4) and thyrotropin (TSH) levels at weaning; on day 90, these rats displayed a significant flip, exhibiting normalised T3 (total and free) and total T4 levels, but low free T4 and persistently higher TSH levels, which were maintained even on postnatal day 140. This profile was accompanied by a scarce fat depot, a lower RMR and an exacerbated sympathetic brown adipose tissue (BAT) tone (deiodinase type 2 expression) in basal conditions. Moreover, when a functional challenge (cold exposure) was applied, the restricted group exhibited partial changes in TSH (29 v. 100%) and T4 (non-response v. 17%) levels, a significant decrease in leptin levels (75 v. 32%) and the maintenance of a sympathetic BAT over-response (higher noradrenaline levels) in comparison with the control group. The findings of the present study suggest that undernutrition during the perinatal period produces permanent changes in the hypothalamus-pituitary-thyroid axis with consequent low body weight and decreased RMR and facultative thermogenesis. We hypothesise that these changes predispose individuals to exhibiting adult subclinical hypothyroidism. PMID:23800456

    The exposure of pregnant females to stress during a critical period of fetal brain development is an environmental risk factor for the development of schizophrenia in adult offspring. Schizophrenia is a group of common mental disorders of unclear origin, affecting approximately 1% of the global population, showing a generally young age at onset. In the present study, a repeated variable stress paradigm was applied to pregnant rats during the final week of gestation. The effects of an extract of Panax ginseng C.A. Meyer (PG) on rats exposed to prenatal stress (PNS) were investigated in terms of behavioral activity and protein expression analyses. In the behavioral tests, grooming behavior in a social interaction test, line-crossing behavior in an open-field test and swimming activity in a forced-swim test were decreased in the rats exposed to PNS compared with the non-stressed offspring; the changes in behavioral activity were reversed upon oral treatment with PG (300 mg/kg). Subsequently, western blot analysis and immunohistochemical analyses of the prefrontal cortex and hippocampus revealed that the downregulation of several neurodevelopmental genes which occurred following exposure to PNS was reversed upon treatment with PG. The current findings demonstrate that the downregulation of several genes following exposure to PNS may affect subsequent behavioral changes, and that these phenomena are reversed following treatment with PG during pregnancy. Our results suggest that oral treatment with PG reduces the incidence of psychiatric disorders, such as schizophrenia. PMID:25394395

  3. Alcohol exposure in utero perturbs retinoid homeostasis in adult rats

    2015-01-01

    Background Maternal alcohol exposure and adult alcohol intake have been shown to perturb the metabolism of various micro- and macro-nutrients, including vitamin A and its derivatives (retinoids). Therefore, it has been hypothesized that the well-known detrimental consequences of alcohol consumption may be due to deregulations of the metabolism of such nutrients rather than to a direct effect of alcohol. Alcohol exposure in utero also has long-term harmful consequences on the health of the offspring with mechanisms that have not been fully clarified. Disruption of tissue retinoid homeostasis has been linked not only to abnormal embryonic development, but also to various adult pathological conditions, including cancer, metabolic disorders and abnormal lung function. We hypothesized that prenatal alcohol exposure may permanently perturb tissue retinoid metabolism, predisposing the offspring to adult chronic diseases. Methods Serum and tissues (liver, lung and prostate from males; liver and lung from females) were collected from 60-75 day-old sprague dawley rats born from dams that were: (I) fed a liquid diet containing 6.7% alcohol between gestational day 7 and 21; or (II) pair-fed with isocaloric liquid diet during the same gestational window; or (III) fed ad libitum with regular rat chow diet throughout pregnancy. Serum and tissue retinoid levels were analyzed by reverse-phase high-performance liquid chromatography (HPLC). Serum retinol-binding protein (RBP) levels were measured by western blot analysis, and liver, lung and prostate mRNA levels of lecithin-retinol acyltransferase (LRAT) were measured by qPCR. Results Retinyl ester levels were significantly reduced in the lung of both males and females, as well as in the liver and ventral prostate of males born from alcohol-fed dams. Tissue LRAT mRNA levels remained unchanged upon maternal alcohol treatment. Conclusions Prenatal alcohol exposure in rats affects retinoid metabolism in adult life, in a tissue- and sex-dependent manner. We propose that the alcohol-induced perturbations of vitamin A metabolism may predispose to detrimental consequnces on adult health. PMID:26312243

    Young people are exposed to and engage in online risky activities, such as disclosing personal information and making unknown friends online. Little research has examined the psychological mechanisms underlying young people's online risk taking. Drawing on fuzzy trace theory, we examined developmental differences in adolescents' and young adults' online risk taking and assessed whether differential reliance on gist representations (based on vague, intuitive knowledge) or verbatim representations (based on specific, factual knowledge) could explain online risk taking. One hundred and twenty two adolescents (ages 13-17) and 172 young adults (ages 18-24) were asked about their past online risk-taking behavior, intentions to engage in future risky online behavior, and gist and verbatim representations. Adolescents had significantly higher intentions to take online risks than young adults. Past risky online behaviors were positively associated with future intentions to take online risks for adolescents and negatively for young adults. Gist representations about risk negatively correlated with intentions to take risks online in both age groups, while verbatim representations positively correlated with online risk intentions, particularly among adolescents. Our results provide novel insights about the underlying mechanisms involved in adolescent and young adults' online risk taking, suggesting the need to tailor the representation of online risk information to different age groups.

    2015-01-01

    The living conditions of young adults in Sweden have changed during the last decades due to the economic and employment situation in society. Although oral health is mainly considered to be good in this age group, their use of dental care has decreased and their priorities and opportunities regarding oral health are little known. The purpose of this study was to describe the views of Swedish young adults on their oral health and oral health-related quality of life (OHRQoL). The design of the study was qualitative, using content analysis. Sixteen young adults, aged 21–29 years, were interviewed. The findings from the interviews were summarized under the theme “Young adults reflected on their OHRQoL in a time perspective” consisting of three categories: “Past experiences, Present situation, and Future prospects.” The OHRQoL of young adults is dependent not only on their own experiences of oral health during childhood and their received dental care but also on their present self-perceived oral health, oral health habits, and social life; together with their expectations of future oral health. The findings in this study indicate that the oral health awareness and needs of young adults, as well as their expectations of oral care, merit further follow-up. PMID:26066517

    Background: Data on the physical strength capabilities are essential for designing safe and usable products and are useful in a wide range of clinical settings especially during treatment of disease affecting the function of the hand. The purpose of this study was to determine peak lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions in a healthy Iranian children and young adult population. Methods: The study was conducted among 511 participants (242 males and 269 females) aged 7-30 years. Measurements were carried out with both dominant and non-dominant hands in standard sitting posture using a B&L pinch gauge. Two repetitions of each strength measurement were recorded for each condition and the average value of the two trials was used in the subsequent analysis. Results: The results showed significant differences in the pinch strength data in terms of the age, gender and hand dominance. The lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions by females were 68.4%, 68.8%, 78.8% and 81.8% of those exerted by males, respectively. Strength exertions with the non-dominant hand were 6.4%, 5.2%, 6.6% and 5.1% lower than strength exertions of the dominant hand for the lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions, respectively. Conclusion: These findings can be used to fill the gaps in strength data for Iranian population. PMID:26000246

    2014-01-01

    Background While a significant minority of prescription drug misusers report purchasing prescription drugs, little is known about prescription drug selling. We build upon past research on illicit drug markets, which increasingly recognizes networks and nightlife as influential, by examining prescription drug market involvement. Methods We use data from 404 young adult prescription drug misusers sampled from nightlife scenes. Using logistic regression, we examine recent selling of and being approached to sell prescription drugs, predicted using demographics, misuse, prescription access, and nightlife scene involvement. Results Those from the wealthiest parental class and heterosexuals had higher odds (OR=6.8) of selling. Higher sedative and stimulant misuse (ORs=1.03), having a stimulant prescription (OR=4.14), and having sold other illegal drugs (OR=6.73) increased the odds of selling. College bar scene involvement increased the odds of selling (OR=2.73) and being approached to sell (OR=2.09). Males (OR=1.93), stimulant users (OR=1.03), and sedative prescription holders (OR=2.11) had higher odds of being approached. Discussion College bar scene involvement was the only site associated with selling and being approached; such participation may provide a network for prescription drug markets. There were also differences between actual selling and being approached. Males were more likely to be approached, but not more likely to sell than females, while the opposite held for those in the wealthiest parental class relative to lower socioeconomic statuses. Given that misuse and prescriptions of sedatives and stimulants were associated with prescription drug market involvement, painkiller misusers may be less likely to sell their drugs given the associated physiological dependence.

  4. Adolescent and young adult medicine is a special and specific area of medical practice.

    PubMed

    Steinbeck, Kate; Towns, Susan; Bennett, David

    2014-06-01

    Adolescent and young adult medicine is a concept that has gained traction in the last decade or so. The medical literature has come primarily from oncology. Advances in neuroscience that document continuing brain development into the third decade, and research that shows risk behaviours associated with adolescence both remain and may increase in the third decade, have been two of the drivers in the conversation around linking these two age groups together as a medical practice group. A third driver of importance is transition care in chronic illness, where older adolescents and young adults continue to have difficulties making effective linkages with adult care. The case for specific training in adolescent and young adult medicine, including the developmental concepts behind it, the benefits of the delineation and the particular challenges in the Australian health-care system, are discussed. On balance, there is a strong case for managing the health issues of adolescents and young adults together. This scenario does not fit easily with the age demarcations that are in place in acute care facilities. However, this is less the case in community services and can work in focused private practice. Such a situation suggests that both paediatric and adult physicians might be interested in adolescent and young adult medicine training and practice. PMID:24547968

    2010-01-01

    Introduction: While young adults have the highest prevalence of cigarette smoking of any adult age group, studies of tobacco and other substance use have reported challenges in recruiting this age group. The Internet may be a useful tool for reaching young adult smokers. The present study compared three Internet-based recruitment methods for young adult smokers to complete a survey about tobacco and other substance use: Craigslist advertisements, other Internet advertisements, and E-mail invitations through a survey sampling service. Methods: Recruitment campaigns invited young adults aged 18–25 years who had smoked at least one cigarette in the past 30 days to complete an online survey. Recruitment methods were compared across recruitment numbers, costeffectiveness, and demographic and smoking characteristics of recruited participants. Results: In 6 months, 920 people gave online consent to determine eligibility to complete the survey, of which 336 (36.5%) were eligible, and 201 (59.8%) completed the survey. While Internet advertisements yielded the largest proportion of recruited participants and completed surveys overall, Craigslist and sampling strategies were more successful at targeting young adult smokers who went on to complete the survey and were more costeffective. Participants differed in demographic and substance use characteristics across the three recruitment mechanisms. Discussion: We identified success at reaching young adults who have smoked cigarettes recently through the Internet, though costs, participant eligibility, proportion of completed surveys, and respondent characteristics differed among the three methods. A multipronged approach to Internet recruitment is most likely to generate a broad diverse sample of young adult smokers. PMID:20530194

    Beta-cyfluthrin (CYF) is a commonly used synthetic pyrethroid having both agricultural and domestic applications. The present study aimed to evaluate the neurobehavioural effects of beta-cyfluthrin in adult rats administered at doses 25 mg/kg body weight/day and 12.5 mg/kg body weight/day for a period of 30 days. Motor coordination and spatial memory were found to be impaired by beta-cyfluthrin. Levels of dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC), epinephrine (EPN), and serotonin (5-HT) decreased in frontal cortex, corpus striatum and hippocampus of treated rats. At the same time, significantly elevated levels of homovanillic acid (HVA) and nor-epinephrine (NE) were measured. Beta-cyfluthrin inhibited the activity of acetylcholinesterase (AChE) in all the regions of the brain. Hippocampal choline acetyltransferase (ChAT) expression was reduced 3.1 and 4.7 fold by the two doses respectively. Impairment of the antioxidant defense system, evident by decrease in the levels of antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) was seen in the treated rats. The neurochemical alterations manifested were more pronounced in the high dose group as the effects persisted even after withdrawal of exposure. PMID:26604153

    We investigated neurofunctional changes associated with source memory decline across the adult life span using functional magnetic resonance imaging (fMRI). Young, middle-aged and old adults carried out a natural/artificial judgment of images of common objects that were randomly presented in one of the quadrants of the screen. At retrieval, the images were displayed at the center of the screen and the participants judged whether each image was new or old and, if old, they indicated in which quadrant of the screen the image had originally been presented. Comparing the items associated with correct versus incorrect source judgments revealed that no regions showed greater activity in young adults than in middle-aged adults; however, in young and middle-aged adults the activity in the left hippocampus and left anterior temporal cortex was of greater magnitude than in the older adults. Several regions also exhibited greater activity in young adults than in old adults. These results suggest that in middle age the recollection neural network, assessable by fMRI, is still preserved.

  20. Purification and culture of adult rat dorsal root ganglia neurons.

    1989-06-01

    To study the trophic requirements of adult rat dorsal root ganglia neurons (DRG) in vitro, we developed a purification procedure that yields highly enriched neuronal cultures. Forty to fifty ganglia are dissected from the spinal column of an adult rat. After enzymatic and mechanical dissociation of the ganglia, myelin debris are eliminated by centrifugation on a Percoll gradient. The resulting cell suspension is layered onto a nylon mesh with a pore size of 10 microns. Most of the neurons, the diameter of which ranged from 17 microns to greater than 100 microns, are retained on the upper surface of the sieve; most of the non-neuronal cells with a caliber of less than 10 microns after trypsinization go through it. Recovery of neurons is achieved by reversing the mesh onto a Petri dish containing culture medium. Neurons to non-neurons ratio is 1 to 10 in the initial cell suspension and 1 to 1 after separation. When these purified neurons are seeded at a density of 3,000 neurons/cm2 in 6 mm polyornithine-laminin (PORN-LAM) coated wells, neuronal survival (assessed by the ability to extend neurites), measured after 48 hr of culture, is very low (from 0 to 16%). Addition of nerve growth factor (NGF) does not improve neuronal survival. However, when neurons are cultured in the presence of medium conditioned (CM) by astrocytes or Schwann cells, 60-80% of the seeded, dye-excluding neurons survive. So, purified adult DRG neurons require for their short-term survival and regeneration in culture, a trophic support that is present in conditioned medium from PNS or CNS glia.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2754765

    Background Head and neck squamous cell carcinoma (HNSCC) is a disease of middle-aged to elderly adults. However, an increased incidence of HNSCC in young people under 45 years of age has been reported recently. In the present review, we focused on the epidemiology and aetiology of HNSCC in adults under 45 years of age. Methods We reviewed literature related to HNSCC in adult patients less than 45 years of age and discussed current treatment options and prognosis. Results HNSCC in young adults is associated with a higher incidence rate in nonsmokers, lower female-to-male ratio, a higher percentage of oral cavity and oropharynx tumours, and fewer second primary tumours. However, aside from traditional risk factors of tobacco and alcohol exposure, the causes of these cancers in young adults remain unclear. Agents that might contribute to risk include infection with high-risk human papillomavirus subtypes as well as genetic factors or immunodeficiency status. The expected increase in incidence and mortality of the young with HNSCC may become a major public health concern if current trends persist, particularly lifestyle habits that may contribute to this disease. Conclusions Given the younger age and potential long-term adverse sequelae of traditional HNSCC treatments, young adults should be treated on a case-by-case basis and post-therapy quality of life must be considered in any treatment-decision making process.

    In order to assess the frequency and profile of cirrhosis in the young, 169 consecutive patients with cirrhosis were studied. Sixty three (37%) patients of less than or equal to 35 years age were defined as young and the remaining 106 (63%) patients (greater than 35 years) as adult cirrhotics. Men predominated significantly (p less than 0.01) in the young cirrhotic group. The aetiology, the frequency of positive hepatitis B markers and initial clinical presentation were similar in the two groups. During the follow up period (30.6 +/- 29.7 months for the young and 25.8 +/- 21.7 months for the adult group), except for abdominal distension and pedal oedema which occurred significantly more often in the adult compared with the young cirrhotics, no difference was noted in the two groups. Twenty seven (39.7%) deaths (40% as a result of hepatic failure and 52% due to variceal bleeding) occurred in the young and 47 (44.3%) deaths (63.8% because of hepatic failure and 26% because of variceal bleeding) occurred in the adult cirrhotics during the follow up (difference NS). The five year survival (61.9% v 55.7%) and the probability of survival within the same Child's grade of liver disease were comparable. In both the groups, however, the probability of survival was significantly higher in Child's A compared with Child's B and C and in Child's B compared with Child's C grade of liver disease. Survival was not influenced by sex of the patient and aetiology of cirrhosis. Results of this prospective study indicate that cirrhosis is not uncommon in young adults. The aetiology, clinical presentation, natural history of the disease and the survival rates in young cirrhotics do not differ significantly from adult cirrhotics. PMID:3343002

    Christakis and colleagues have shown that health behaviors cluster in social networks and suggest social norms may account for the clustering. This study examined: 1) whether obesity clusters among young adults and whether social norms do in fact account for the clustering, and 2) among OW/OB young adults, whether number of social contacts trying to lose weight is associated with weight loss intentions and whether social norms for weight loss account for this effect. Normal weight (NW) and OW/OB young adults (N=288; 66%Female; 75%Caucasian) completed measures assessing number of OW social contacts and social norms for obesity. OW/OB young adults also indicated number of OW social contacts currently trying to lose weight, social norms for weight loss, and weight loss intentions. Compared to NW, OW/OB young adults were more likely to have OW romantic partners and best friends and had more OW casual friends and family members (p's<.05), but social norms for obesity did not differ between groups, and social norms did not mediate the relationship between OW social contacts and participants' weight status. However, among OW/OB young adults, having more social contacts trying to lose weight was associated with greater intention to lose weight (r=.20, p=.02) and social norms for weight loss fully mediated this effect (p<.01). This study is the first to show that social contacts and normative beliefs influence weight status and intentions for weight control in young adults. Findings underscore the importance of targeting social influence in the treatment and prevention of obesity in this high-risk age group. PMID:21164501

  5. Neural Mechanisms of Reading Facial Emotions in Young and Older Adults

    The ability to read and appropriately respond to emotions in others is central for successful social interaction. Young and older adults are better at identifying positive than negative facial expressions and also expressions of young than older faces. Little, however, is known about the neural processes associated with reading different emotions, particularly in faces of different ages, in samples of young and older adults. During fMRI, young and older participants identified expressions in happy, neutral, and angry young and older faces. The results suggest a functional dissociation of ventromedial prefrontal cortex (vmPFC) and dorsomedial prefrontal cortex (dmPFC) in reading facial emotions that is largely comparable in young and older adults: Both age groups showed greater vmPFC activity to happy compared to angry or neutral faces, which was positively correlated with expression identification for happy compared to angry faces. In contrast, both age groups showed greater activity in dmPFC to neutral or angry than happy faces which was negatively correlated with expression identification for neutral compared to happy faces. A similar region of dmPFC showed greater activity for older than young faces, but no brain-behavior correlations. Greater vmPFC activity in the present study may reflect greater affective processing involved in reading happy compared to neutral or angry faces. Greater dmPFC activity may reflect more cognitive control involved in decoding and/or regulating negative emotions associated with neutral or angry than happy, and older than young, faces.

  6. Some factors influencing cadmium-manganese interaction in adult rats

    1989-07-01

    Recent data show that even a low dose of cadmium (20 {mu}g/day/rat) significantly suppresses manganese transduodenal transport when administered during a three-day period. The inhibitory effect of cadmium upon manganese absorption is enhanced by concurrently administered iron-fortified milk diet. This suggests that the (synergistic) action of cadmium and iron upon manganese and the competition between these (three) ions in the intestine depend on their relative concentrations and affinity for the binding sites within the intestinal mucosa. For this reason the authors considered it worthwhile examining whether this inhibitory effect of cadmium would be affected by simultaneously administered manganese-fortified milk. Since the absorption of heavy metals and, at the same time, the demand for manganese is higher in the young than in the old animals, they also studied how this interaction depends upon the animals' age and sex and whether it is the same in the whole small intestine.

    Although treatment outcome research on dissociative disorders (DD) is increasing, an examination of treatment progress in young adults with these disorders remains noticeably absent from the literature. Many studies of DD patients report mean ages over 35. The present study examined the response to treatment of a subsample of young adults ages 18-30 with dissociative identity disorder and dissociative disorder not otherwise specified who participated in a naturalistic, longitudinal study of DD treatment outcome. Over 30 months, these patients demonstrated decreases in destructive behaviors and symptomatology as well as improved adaptive capacities. Compared to the older adult participants in the study, the young adults were more impaired initially. However, these younger patients improved at a rapid pace, such that their clinical presentations were similar to or more improved than those of the older adults at the 30-month follow-up. This brief report suggests not only that young adult DD patients can benefit from a trauma-focused, phasic treatment approach but that their treatment may progress at a faster pace than that of older adults with DD.

  8. Explanation for the labeling of cervical motoneurons in young rats following the introduction of horseradish peroxidase into the calf.

    PubMed

    Haase, P

    1990-07-15

    This study was carried out to determine whether cervical motoneurons, labeled following the introduction of horseradish peroxidase into the rat hind leg, belong to the cutaneous trunci motoneuron pool. The cutaneous trunci is a superficial muscle that extends from the axilla, over the flank, and into the thigh. Its nerve supply is derived from the brachial plexus. In experimental animals, horseradish peroxidase was either injected directly into the right gastrocnemius muscles, or applied to gelfoam and implanted over the calf muscles in the right leg of 5-, 10-, 15-day-old and adult rats. In control animals the cutaneous trunci was denervated prior to the administration of horseradish peroxidase. Labeled cervical motoneurons were present in the 5-, 10-, and 15-day-old but not the adult experimental groups and were located within the predetermined confines of the cutaneous trunci motoneuron pool. No labeling of cervical motoneurons was observed in any of the control groups in which the cutaneous trunci muscle was denervated. The most likely explanation for the labeling of cervical motoneurons in young rats was the local diffusion of horseradish peroxidase from the calf to the thigh, where it entered the cutaneous trunci muscle and was taken up by some of its motoneurons. The absence of such labeling in adult rats was probably due to the presence of connective tissue barriers to diffusion and to the greater distance between the site of horseradish peroxidase application and the cutaneous trunci muscle, which prevented the tracer from reaching the cutaneous trunci muscle and labeling its motoneurons.

    Erythropoietic repopulating abilities of fetal liver cells and young and old adult marrow cells were compared as follows: Equal numbers of cells from a donor of each age were mixed with a constant portion of cells pooled from genetically distinguishable competitors. These mixtures were transplanted into stem cell-depleted recipients, and the proportions of recipient hemoglobin that were donor type measured the relative effectiveness of early erythropoietic precursor cells from the various donors. At intervals of 3-6 mo, recipients were sublethally irradiated, requiring a new round of competitive repopulation. When B6 mice were used as donors, with WBB6F1 competitors and recipients, the highest levels of stem cell activity were found using old donors. This was true even with unirradiated, immune-competent W/Wv recipients. When donors and recipients were WBB6F1 hybrids, with B6 competitors, fetal cells initially gave higher levels of repopulating ability, and they were similar to the adult and old marrow cells after 400 d and after recovery from two sublethal irradiations. These effects were mostly insignificant and probably reflect small differences in initial stem cell concentrations that are brought out by the sensitivity of the competitive repopulation assay. Repopulating abilities of 12-d fetal liver cells were not detectable. We also showed that the proportions of newly synthesized hemoglobins made by the two types of stem cells in tetraparental mice remained nearly constant when tested at 3-d intervals over 30 d. Minimum numbers of stem cells producing erythrocytes over a single 3-d period were calculated as 62 and 128, but these are too low, since variances were similar in the tetraparental mice and in the F1 hybrid control. We suggest that erythropoietic stem cells have essentially unlimited proliferative capacities and are found in approximately equal concentrations in the primary erythropoietic organs after 15 or 16 d of fetal life.

    The transition from pediatric to adult health care is often challenging for adolescents and young adults with sickle cell disease (SCD). Our study aimed to identify (1) measures of success for the transition to adult health care; and (2) barriers and facilitators to this process. We interviewed 13 SCD experts and asked them about their experiences caring for adolescents and young adults with SCD. Our interview guide was developed based on Social-Ecological Model of Adolescent and Young Adult Readiness to Transition framework, and interviews were coded using the constant comparative method. Our results showed that transition success was measured by health care utilization, quality of life, and continuation on a stable disease trajectory. We also found that barriers to transition include negative experiences in the emergency department, sociodemographic factors, and adolescent skills. Facilitators include a positive relationship with the provider, family support, and developmental maturity. Success in SCD transition is primarily determined by the patients' quality of relationships with their parents and providers and their developmental maturity and skills. Understanding these concepts will aid in the development of future evidence-based transition care models. PMID:26492583

    The objectives of this study are to compare the Autobiographical Memory Test (AMT) performance of two healthy samples of younger and older adults and to analyse the relationship between overgeneral memory (OGM) and working memory executive processes (WMEP) using a structural equation modelling with latent variables. The AMT and sustained attention, short-term memory and working memory tasks were administered to a group of young adults (N = 50) and a group of older adults (N = 46). On the AMT, the older adults recalled a greater number of categorical memories (p = .000) and fewer specific memories (p = .000) than the young adults, confirming that OGM occurs in the normal population and increases with age. WMEP was measured by reading span and a working memory with sustained attention load task. Structural equation modelling reflects that WMEP shows a strong relationship with OGM: lower scores on WMEP reflect an OGM phenomenon characterized by higher categorical and lower specific memories.

    Gastrointestinal stromal tumors (GISTs) typically occur late in life; however, there also are reports of pediatric and young adult patients. This rare subset of GISTs has clinicopathologic and molecular features distinct from their adult counterparts. Most pediatric GIST patients are female and often present with multifocal tumors that are epithelioid in nature. Although these young patients often have metastatic disease, it progresses slowly. Most pediatric GISTs lack the gain-of-function mutation in KIT or PDGFRA commonly found in adult cases. Expression profiling and genomic studies of pediatric GISTs show distinct molecular signatures, suggesting a unique origin as compared with adult GISTs. We and others have shown that the insulin-like growth factor 1 receptor may have a prominent role in driving KIT/PDGFRA mutation-negative adult and pediatric GISTs, and clinical trials are currently being designed to exploit these types of discoveries.

    2013-01-01

    Background Research on the quality of diabetes care provided to young adults with Type 1 diabetes is lacking. This study investigates perceptions of quality of care for young adults with Type 1 diabetes (23–30 years old) living in the Republic of Ireland. Methods Thirty-five young adults with Type 1 diabetes (twenty-nine women, six men) and thirteen healthcare professionals (ten diabetes nurse specialists, three consultant Endocrinologists) were recruited. All study participants completed semi-structured interviews that explored their perspectives on the quality of diabetes services in Ireland. Interviews were analyzed using standard qualitative thematic analysis techniques. Results Most interviewees identified problems with Irish diabetes services for young adults. Healthcare services were often characterised by long waiting times, inadequate continuity of care, overreliance on junior doctors and inadequate professional-patient interaction times. Many rural and non-specialist services lacked funding for diabetes education programmes, diabetes nurse specialists, insulin pumps or for psychological support, though these services are important components of quality Type 1 diabetes healthcare. Allied health services such as psychology, podiatry and dietician services appeared to be underfunded in many parts of the country. While Irish diabetes services lacked funding prior to the recession, the economic decline in Ireland, and the subsequent austerity imposed on the Irish health service as a result of that decline, appears to have additional negative consequences. Despite these difficulties, a number of specialist healthcare services for young adults with diabetes seemed to be providing excellent quality of care. Although young adults and professionals identified many of the same problems with Irish diabetes services, professionals appeared to be more critical of diabetes services than young adults. Young adults generally expressed high levels of satisfaction with services, even where they noted that aspects of those services were sub-optimal. Conclusion Good quality care appears to be unequally distributed throughout Ireland. National austerity measures appear to be negatively impacting health services for young adults with diabetes. There is a need for more Endocrinologist and diabetes nurse specialist posts to be funded in Ireland, as well as allied health professional posts. PMID:24168159

    Background Among Hispanics, lung cancer is the leading cause of cancer-related death for men and the second leading cause of cancer death for women in the United States. Despite recent growth in Baltimore City’s Hispanic population, few data exist on tobacco use behaviors in this group. Objectives The present research sought to explore the social and environmental influences and norms that encourage or discourage tobacco use among Hispanic young adults in Baltimore. Methods In collaboration with several community stakeholders, we conducted focus groups with Hispanic young adults 18 to 24 years old. Participants were recruited from a community-based service organization and invited to take part in one of four focus groups segregated by gender. Results A total of 13 young men and 11 young women participated. Data from these focus groups indicate that cultural identity and gender norms leverage substantial influence in young adults’ decision about whether, where, and with whom to smoke. The data also suggest multiple social and familial influences on their smoking and nonsmoking behaviors. Participants identified smoking practices and clear brand preferences that they feel distinguish Hispanics from other racial and ethnic groups. Despite acknowledging the high price of cigarettes, cost was not mentioned as a factor influential in their smoking decisions. Conclusion These results provide essential guidance for the development of appropriate tobacco prevention and cessation intervention strategies and policy recommendations to eliminate tobacco use among Hispanic young adults in Baltimore.

    Objectives. We sought to describe changes in young adults’ routine care and usual sources of care (USCs), according to provider specialty, after implementation of extended dependent coverage under the Affordable Care Act (ACA) in 2010. Methods. We used Medical Expenditure Panel Survey data from 2006 to 2012 to examine young adults’ receipt of routine care in the preceding year, identification of a USC, and USC provider specialties (pediatrics, family medicine, internal medicine, and obstetrics and gynecology). Results. The percentage of young adults who sought routine care increased from 42.4% in 2006 to 49.5% in 2012 (P?young adults with a USC, there was a trend between 2006 and 2012 toward increasing percentages with pediatric (7.6% vs 9.1%) and family medicine (75.9% vs 80.9%) providers and declining percentages with internal medicine (11.5% vs 7.6%) and obstetrics and gynecology (5.0% vs 2.5%) providers. Conclusions. Efforts under the ACA to increase health insurance coverage had favorable effects on young adults’ use of routine care. Monitoring routine care use and USC choices in this group can inform primary care workforce needs and graduate medical education priorities across specialties. PMID:26447914

    Objectives. We synthesized evidence regarding effective strategies for smoking cessation among employed or unemployed young adults aged 18 to 24 years. Methods. For this knowledge synthesis, we used (1) a systematic review of the scientific literature, (2) a Delphi panel of experts, and (3) 6 focus groups of employed and unemployed young adult smokers. Results. Of 51 related studies, only 4 included employed and unemployed young adults in their samples (as opposed to students), and none focused solely on them. Using the Delphi process, 27 experts reached consensus on priorities for research, practice, and policy, emphasizing population engagement, recruitment, and innovative interventions. Key themes from focus groups were that interventions should be relevant to young adults, individual choice should be respected, and the positive aspects of quitting should be stressed. Despite having negative views on traditional smoking cessation methods, participants expressed optimism about being able to quit and proposed creative recommendations. Conclusions. Our findings set an agenda for targeting research, improving practice, and informing policy for smoking cessation among young adults. We also demonstrate the value of using 3 complementary approaches: literature review, expert opinion, and target population perspectives. PMID:17600254

    Purpose Young adult survivors of childhood and adolescent cancer are an ever-growing population of patients, many of whom remain at lifelong risk for potentially serious complications of their cancer therapy. Yet research shows that many of these older survivors have deficient health-related knowledge and are not engaging in recommended health promotion and screening practices that could improve their long-term outcomes. The purpose of this review is to address these disparities by discussing how formal transition of care from pediatric to adult-focused survivorship services may help meet the unique medical, developmental, and psychosocial challenges of these young adults. Design Literature review and discussion. Results This article summarizes current research documenting the medical needs of young adult survivors, their suboptimal compliance with recommended follow-up, and the rationale, essential functions, current models, and innovative approaches for transition of follow-up care. Conclusion Systematic health care transition constitutes the standard of care for young adult survivors of childhood cancer. In developing a transitional care program, it is necessary to consider the scope of services to be provided, available resources, and other local exigencies that help determine the optimal model for use. Additional research is needed to improve health services delivery to this population. Effective advocacy is needed, particularly in the United States, to ensure the availability of uninterrupted health insurance coverage for survivorship services in young adulthood. PMID:20351333

    Introduction Smoking both cigarettes and marijuana is increasingly common among young adults, yet little is known about use patterns, motivations, or thoughts about abstinence. In a U.S. sample, this study explored young adults’ severity of cigarette and marijuana co-use, quit attempts, and thoughts about use. Methods Young adults age 18-to-25 who had smoked at least one cigarette in the past 30 days completed an anonymous online survey. Results Of 1987 completed surveys, 972 participants reported both past-month cigarette and marijuana use (68% male, 71% Caucasian, mean age 20.4 years [SD=2.0]). Frequency of use, temptations to use, measures of dependence, decisional balance, and past-year quit attempts were associated across the two substances (all p< .05), but not motivation to quit. Relative to marijuana, participants reported greater desire and a later stage of change for quitting cigarettes and were more likely to endorse a cigarette abstinence goal, yet they had lower expectancy of success with quitting cigarettes and with staying quit (all p<.001). Conclusions Cigarette and marijuana use, temptations to use, and pros/cons of using were related in this young adult sample. Differences in motivation and thoughts about abstinence, however, suggest that young adults may be more receptive to interventions for tobacco than marijuana use. Use patterns and cognitions for both substances should be considered in prevention and intervention efforts. PMID:24090626

    AIM To describe and compare the differences in electroretinographic responses between two different age groups of adult Dark Agouti (DA) rats and to better understand the effect of age on retinal histology and function. METHODS The electroretinographic responses of two different age groups of adult DA rats were compared. Animals were divided into younger adult DA rats 10-12wk (n=8) and older adult DA rats 17-19wk (n=8). Full field electroretinography (ERG) was recorded simultaneously from both eyes after dark adaption and light adaption and parameters including the positive scotopic threshold response (pSTR), negative scotopic threshold response (nSTR), scotopic a-wave, b-wave, photopic a-wave, b-wave and photopic negative response (PhNR) were compared between groups. RESULTS The older adult rats displayed lower stimulation thresholds of the STRs (pSTR and nSTR) and higher amplitudes of pSTR, scotopic a-wave and b-wave, photopic b-wave and PhNR amplitudes, with shorter implicit times. Photopic a-wave amplitudes were however higher in the younger adult rats. CONCLUSION In summary, for the rod system, photoreceptor, bipolar cell and RGC activity was enhanced in the older adult rats. For the cone system, RGC and bipolar cell activity was enhanced, while photoreceptor activity was depressed in the older adult rats. Such age-related selective modification of retinal cell function needs to be considered when conducting ophthalmic research in adult rats. PMID:26558198

    Abstract Background: Evidence suggests nonelderly adults with cancer are likely to receive aggressive treatment in their last month of life and less likely to receive hospice and/or palliative services. Young adults with cancer (18–39 years) are a unique population, and little is known about the characteristics of their end-of-life care trajectories when they die in the hospital. Objective: The purpose of this descriptive pilot study was to explore the characteristics of death among young adults with cancer who died in a tertiary academic hospital in order to elucidate their end-of-life trajectories. Methods: A retrospective chart review was conducted among hospitalized young adults with a primary cancer diagnosis who died in the hospital within a 10-year period. Study variables were abstracted for quantification and medical record notes were reviewed for validation. Results: A review of 61 patient records indicate that young adults commonly received cancer treatment within weeks of death and that do-not-resuscitate orders were frequently written only when death appeared imminent. Palliative care teams were frequently consulted for management of physical symptoms but often within days of death and most commonly on the day of death. Conclusions: Findings suggest palliative care was initiated late in the care trajectory for young adults with cancer who died in the hospital. This study highlights the need for further inquiry into end-of-life care for young adults with cancer so that interventions can be developed to meet the physical, emotional, social, and spiritual needs of this unique group of patients, their families, and friends.

    Despite the intensive investigation of bimanual coordination, it remains unclear how directing vision toward either limb influences performance, and whether this influence is affected by age. To examine these questions, we assessed the performance of young and older adults on a bimanual tracking task in which they matched motor-driven movements of their right hand (passive limb) with their left hand (active limb) according to in-phase and anti-phase patterns. Performance in six visual conditions involving central vision, and/or peripheral vision of the active and/or passive limb was compared to performance in a no vision condition. Results indicated that directing central vision to the active limb consistently impaired performance, with higher impairment in older than young adults. Conversely, directing central vision to the passive limb improved performance in young adults, but less consistently in older adults. In conditions involving central vision of one limb and peripheral vision of the other limb, similar effects were found to those for conditions involving central vision of one limb only. Peripheral vision alone resulted in similar or impaired performance compared to the no vision (NV) condition. These results indicate that the locus of visual attention is critical for bimanual motor control in young and older adults, with older adults being either more impaired or less able to benefit from a given visual condition.

    Opiate use patterns, user characteristics, and treatment response among young adults are of interest due to current high use prevalence and historical low levels of treatment engagement relative to older populations. Prior research in this population suggests that overall, young adults present at treatment with different issues. In this study the authors investigated potential differences between young adult (18-25 years of age) and older adult (26 and older) opiate users and the impact of differences relative to treatment motivation, length and outcomes. Data for this study was drawn from 760 individuals who entered voluntary, private, residential treatment. Study measures included the Addiction Severity Index (ASI), the Treatment Service Review (TSR), and University of Rhode Island Change Assessment (URICA). Interviews were conducted at program intake and 6-month post-discharge. Results indicate that older adults with a history of opiate use present at treatment with higher levels of severity for alcohol, medical, and psychological problems and young adults present at treatment with greater drug use and more legal issues. Significant improvement for both groups was noted at 6 months post treatment; there were also fewer differences between the two age groups of opiate users. Results suggest different strategies within treatment programs may provide benefit in targeting the disparate needs of younger opiate users. Overall, however, results suggest that individualized treatment within a standard, abstinence-based, residential treatment model can be effective across opiate users at different ages and with different issues, levels of severity, and impairment at intake.

    People with grapheme-color synesthesia perceive enriched experiences of colors in response to graphemes (letters, digits). In this study, we examined whether these synesthetes show a generic associative memory advantage for stimuli that do not elicit a synesthetic color. We used a novel between group design (14 young synesthetes, 14 young, and 14 older adults) with a self-paced visual associative learning paradigm and subsequent retrieval (immediate and delayed). Non-synesthesia inducing, achromatic fractal pair-associates were manipulated in visual similarity (high and low) and corresponded to high and low memory load conditions. The main finding was a learning and retrieval advantage of synesthetes relative to older, but not to younger, adults. Furthermore, the significance testing was supported with effect size measures and power calculations. Differences between synesthetes and older adults were found during dissimilar pair (high memory load) learning and retrieval at immediate and delayed stages. Moreover, we found a medium size difference between synesthetes and young adults for similar pair (low memory load) learning. Differences between young and older adults were also observed during associative learning and retrieval, but were of medium effect size coupled with low power. The results show a subtle associative memory advantage in synesthetes for non-synesthesia inducing stimuli, which can be detected against older adults. They also indicate that perceptual mechanisms (enhanced in synesthesia, declining as part of the aging process) can translate into a generic associative memory advantage, and may contribute to associative deficits accompanying healthy aging.

    The NMDA antagonist, memantine (Namenda), and the cholinesterase inhibitor, donepezil (Aricept), are currently being used widely, either individually or in combination, for treatment of Alzheimer’s disease (AD). NMDA antagonists have both neuroprotective and neurotoxic properties; the latter is augmented by drugs, such as pilocarpine, that increase cholinergic activity. Whether donepezil, by increasing cholinergic activity, might augment memantine’s neurotoxic potential has not been investigated. In the present study, we determined that a dose of memantine (20 mg/kg ip), considered to be in the therapeutic (neuroprotective) range for rats, causes a mild neurotoxic reaction in the adult rat brain. Co-administration of memantine (20 or 30 mg/kg) with donepezil (2.5 to 10mg/kg) markedly potentiated this neurotoxic reaction, causing neuronal injury at lower doses of memantine, and causing the toxic reaction to become disseminated and lethal to neurons throughout many brain regions. These findings raise questions about using this drug combination in AD, especially in the absence of evidence that the combination is beneficial, or that either drug arrests or reverses the disease process.

    The brain continues to develop through adolescence when excessive alcohol consumption is prevalent in humans. We hypothesized that binge drinking doses of ethanol during adolescence will cause changes in brain ethanol responses that persist into adulthood. To test this hypothesis Wistar rats were treated with an adolescent intermittent ethanol (AIE; 5 g/kg, i.g. 2 days on-2 days off; P25-P54) model of underage drinking followed by 25 days of abstinence during maturation to young adulthood (P80). Using markers of neuronal activation c-Fos, EGR1, and phophorylated extracellar signal regulated kinase (pERK1/2), adult responses to a moderate and binge drinking ethanol challenge, e.g., 2 or 4 g/kg, were determined. Adult rats showed dose dependent increases in neuronal activation markers in multiple brain regions during ethanol challenge. Brain regional responses correlated are consistent with anatomical connections. AIE led to marked decreases in adult ethanol PFC (prefrontal cortex) and blunted responses in the amygdala. Binge drinking doses led to the nucleus accumbens (NAc) activation that correlated with the ventral tegmental area (VTA) activation. In contrast to other brain regions, AIE enhanced the adult NAc response to binge drinking doses. These studies suggest that adolescent alcohol exposure causes long-lasting changes in brain responses to alcohol that persist into adulthood. PMID:25727639

    Nessler, Johnson, Bersick, and Friedman (D. Nessler, R. Johnson, Jr., M. Bersick, & D. Friedman, 2006, On why the elderly have normal semantic retrieval but deficient episodic encoding: A study of left inferior frontal ERP activity, NeuroImage, Vol. 30, pp. 299-312) found that, compared with young adults, older adults show decreased event-related brain potential (ERP) activity over posterior left inferior prefrontal cortex (pLIPFC) in a 400- to 1,400-ms interval during episodic encoding. This altered brain activity was associated with significantly decreased recognition performance and reduced recollection-related brain activity at retrieval (D. Nessler, D. Friedman, R. Johnson, Jr., & M. Bersick, 2007, Does repetition engender the same retrieval processes in young and older adults? NeuroReport, Vol. 18, pp. 1837-1840). To test the hypothesis that older adults' well-documented episodic retrieval deficit is related to reduced pLIPFC activity at encoding, we used a novel divided attention task in healthy young adults that was specifically timed to disrupt encoding in either the 1st or 2nd half of a 300- to 1,400-ms interval. The results showed that diverting resources for 550 ms during either half of this interval reproduced the 4 characteristic aspects of the older participants' retrieval performance: normal semantic retrieval during encoding, reduced subsequent episodic recognition and recall, reduced recollection-related ERP activity, and the presence of "compensatory" brain activity. We conclude that part of older adults' episodic memory deficit is attributable to altered pLIPFC activity during encoding due to reduced levels of available processing resources. Moreover, the findings also provide insights into the nature and timing of the putative "compensatory" processes posited to be used by older adults in an attempt to compensate for age-related decline in cognitive function. These results support the scaffolding account of compensation, in which the recruitment of additional cognitive processes is an adaptive response across the life span. PMID:23276214

    The present work aimed to investigate the effects of acute sucrose treatment on the perception of painful stimuli. Specifically, we sought to determine the involvement of the endogenous opioid peptide-mediated system as well as the role of the ?(1)-opioid receptor in antinociception organisation induced by acute sucrose intake. Nociception was assessed with the tail-flick test in rats (75, 150 and 250 g) of different ages acutely pre-treated with 500 ?L of a sucrose solution (25, 50, 150 and 250 g/L) or tap water. Young and Adult rats (250 g) showed antinociception after treatment with 50 g/L (during 5 min) and 150 g/L and 250 g/L (during 20 min) sucrose solutions. Surprisingly, this antinociception was more consistent in mature adult rodents than in pups. To evaluate the role of opioid systems, mature adult rodents were pre-treated with different doses (0.25, 1 or 4 mg/kg) of the non-selective opioid receptor antagonist naloxone, the selective ?(1)-opioid receptor antagonist naloxonazine or vehicle followed by 250 g/L sucrose solution treatment. Sucrose-induced antinociception was reduced by pre-treatment with both naloxone and naloxonazine. The present findings suggest that sweet substance-induced hypo-analgesia is augmented by increasing sucrose concentrations in young and adult rodents. Acute oral sucrose treatment inhibits pain in laboratory animal by mediating endogenous opioid peptide and ?(1)-opioid receptor actions. PMID:22197708

    Many lesbian, gay, bisexual, and transgender (LGBT) adolescents disclose their sexual and/or gender identities to peers at school. Disclosure of LGBT status is linked with positive psychosocial adjustment for adults; however, for adolescents, "coming out" has been linked to school victimization, which in turn is associated with negative adjustment. This study investigates the associations among adolescent disclosure of LGBT status to others at school, school victimization, and young adult psychosocial adjustment using a sample of 245 LGBT young adults (aged 21-25 years, living in California). After accounting for the association between school victimization and later adjustment, being out at high school was associated with positive psychosocial adjustment in young adulthood. Results have significant implications for training of school-based health and mental health providers, education and guidance for parents and caregivers, fostering positive development of LGBT youth, and developing informed school policies and educational practices.

    The purpose of this literature review is to make a point on the state of health of adolescents and young adults (15-25 years) suffering from cancer. The adaptation strategies and the impact of the announcement of cancer will be discussed. In addition, we are going to consider the characteristics of teenagers and young adults, given the fact that development is still in progress. This period is especially punctuated by various experiments and the emergence of some clinical signs. Also, we have identified various studies concerning the use of licit and illicit substances. Furthermore, we have taken interest in behavioral addictions, particularly cyber addiction. While trying to cross these variables with a population of teenagers and young adults in the context of somatic diseases, it occurred that this population was not well known and studied. The interest of this synthesis is to underline the importance to make future researches in these perspectives. PMID:25953377

    This is the first known study to explore how religious identity conflict impacts suicidal behaviors among lesbian, gay, bisexual, and transgender (LGBT) young adults and to test internalized homophobia as a mediator. A secondary analysis of 2,949 youth was conducted using a national dataset collected by OutProud in 2000. Three indicators of identity conflict and an internalized-homophobia scale (mediator), were included in logistic regressions with three different suicide variable outcomes. Internalized homophobia fully mediates one conflict indicator and partially mediates the other two indicators' relationship with suicidal thoughts. Internalized homophobia also fully mediates the relationship between one conflict indicator and chronic suicidal thoughts. Two indicators were associated with twice the odds of a suicide attempt. LGBT young adults who mature in religious contexts have higher odds of suicidal thoughts, and more specifically chronic suicidal thoughts, as well as suicide attempt compared to other LGBT young adults. Internalized homophobia only accounts for portions of this conflict. PMID:25763926

    A descriptive, exploratory study of 76 young adult women enrolled in a women's health course at a large, midwestern university was undertaken to identify their current health status, health perceptions, and general health behaviors. Two groups of young adult females participated, nursing students (n = 38) and non-nursing students (n = 38). The panel of young adult women in this study reported their health as good or excellent, viewed health as very important and generally used positive health practices. However, data revealed that the lifestyles of many respondents were not conducive to promoting or maintaining health. Negative health practices identified were drinking and driving, non-performance of self breast examinations, ineffective stress management strategies and poor dietary and exercise habits. No significant differences were noted between nursing and non-nursing students. PMID:8288422

    Factors that contribute to an increased prevalence of squamous cell carcinoma of the upper aerodigestive tract among young adults in the United States remain unknown. A potential etiologic factor may relate to a genetically controlled sensitivity to environmental carcinogens. This study, therefore, examined 20 young adult patients who had squamous cell carcinoma for mutagen-induced chromosome sensitivity. Lymphocytes from respective patients were cultured, exposed to the clastogen bleomycin, arrested during metaphase, and examined quantitatively for chromosome breakage. The young adult population with squamous cell carcinoma expressed a significantly increased number of bleomycin-induced chromosome breaks per cell. Furthermore, among the study patients, chromosome sensitivity was most apparent in the non-tobacco users and in patients less than 30 years of age. The expression of such chromosome fragility following mutagen exposure should be considered in epidemiologic studies that intend to define risk factors for development of head and neck cancer.

    In the United States, Europe, and Australia, and probably all countries of the world, older adolescents and young adults with cancer are under-represented in clinical trials of therapies that could improve their outcome. Simultaneously, the survival and mortality rates in these patients have mirrored the clinical trial accrual pattern, with little improvement compared with younger and older patients. This suggests that the relative lack of participation of adolescent and young adult patients in clinical trials has lessened their chances for as good an outcome as that enjoyed by patients in other age groups. Thus, increased availability of and participation in clinical trials is of paramount important if the current deficits in outcome in young adults and older adolescents are to be eliminated. Regardless of whether there is a causal relationship, the impact of low clinical trial activity on furthering our scientific knowledge and management of cancer during adolescence and early adulthood is detrimental.

    Normal aging is associated with disruption of neural systems that subserve different aspects of cognitive function, particularly in the hippocampus and frontal cortex. Abnormalities in hippocampal function have been well investigated in rodent models of aging, but studies of frontal cortex function in aged rodents are few. We tested young (4–5 mo old) and aged (27–28 mo old) male Long-Evans rats on an attentional set-shifting task modified slightly from previous publication. After training on two problems in which the reward was consistently associated with the same stimulus dimension, and a reversal of one problem, a new problem was presented in which the reward was consistently associated with the previously irrelevant stimulus dimension (extradimensional shift [EDS]). Aged rats as a group were significantly impaired on the EDS, although some individual aged rats performed as well as young rats on this phase. In addition, some aged rats were impaired on the reversal, although a group effect did not reach significance in this phase. Impairment in neither reversal nor EDS was associated with impairments in spatial learning in the Morris water maze. Young rats with neurotoxic lesions of medial frontal cortex are also selectively impaired on the EDS. These results indicate that normal aging in rats is associated with impaired medial frontal cortex function. Furthermore, age-related declines in frontal cortex function are independent of those in hippocampal function. These results provide a possible basis for correlating age-related changes in neurobiological markers in frontal cortex with cognitive decline. PMID:12177232

    Proofreading text relies on stored knowledge, language processing, and attentional resources. Age differentially affects these constituent abilities: while older adults maintain word knowledge and most aspects of language comprehension, language production and attention capacity are impaired with age. Research with young adults demonstrates that proofreading is more attentionally-demanding for contextual errors which require integration across multiple words compared to noncontextual errors which occur within a single word. Proofreading is also more attentionally-demanding for text which is more difficult to comprehend compared to easier text. Older adults may therefore be impaired at aspects of proofreading which require production, contextual errors, or more difficult text. The current study tested these possibilities using a naturalistic proofreading task. Twenty-four young and 24 older adults proofread noncontextual (spelling) and contextual (grammar or meaning) errors in passages that were easier or more difficult to comprehend. Older adults were preserved at proofreading spelling errors, but were impaired relative to young adults when proofreading grammar or meaning errors, especially for difficult passages. Additionally, older adults were relatively spared at detecting errors compared to correcting spelling errors, in keeping with previous research. Age differences were not attributable to individual differences in vocabulary knowledge or self-reported spelling ability. PMID:26580634

    Young and older adults studied word pairs and later discriminated studied pairs from various types of foils including recombined word-pairs and foil pairs containing one or two previously unstudied words. We manipulated how many times a specific word pair was repeated (1 or 5) and how many different words were associated with a given word (1 or 5) to tease apart the effects of item familiarity from recollection of the association. Rather than making simple old/new judgments, subjects chose one of five responses: (1) Old-Old (original), (2) Old-Old (rearranged), (3) Old-New, (4) New-Old, (5) New-New. Veridical recollection was impaired in old age in all memory conditions. There was evidence for a higher rate of false recollection of rearranged pairs following exact repetition of study pairs in older but not younger adults. In contrast, older adults were not more susceptible to interference than young adults when one or both words of the pair had multiple competing associates. Older adults were just as able as young adults to use item familiarity to recognize which word of a foil was old. This pattern suggests that recollection problems in advanced age are due to a deficit in older adults’ formation or retrieval of new associations in memory. A modeling simulation provided good fits to these data and offers a mechanistic explanation based on an age-related reduction of working memory. PMID:20973609

Proofreading is also more attentionally-demanding for text which is more difficult to comprehend compared to easier text. Older adults may therefore be impaired at aspects of proofreading which require production, contextual errors, or more difficult text. The current study tested these possibilities using a naturalistic proofreading task. Twenty-four young and 24 older adults proofread noncontextual (spelling) and contextual (grammar or meaning) errors in passages that were easier or more difficult to comprehend. Older adults were preserved at proofreading spelling errors, but were impaired relative to young adults when proofreading grammar or meaning errors, especially for difficult passages. Additionally, older adults were relatively spared at detecting errors compared to correcting spelling errors, in keeping with previous research. Age differences were not attributable to individual differences in vocabulary knowledge or self-reported spelling ability. PMID:26580634

    Background Social media has emerged as a potentially powerful medium for communication with adolescents and young adults around their health choices. Objective The goal of this systematic review is to identify research on the use of social media for interacting with adolescents and young adults in order to achieve positive health outcomes. Methods A MEDLINE/PubMed electronic database search was performed between January 1, 2002 and October 1, 2013, using terms to identify peer-reviewed research in which social media and other Web 2.0 technologies were an important feature. We used a systematic approach to retrieve papers and extract relevant data. Results We identified 288 studies involving social media, of which 87 met criteria for inclusion; 75 studies were purely observational and 12 were interventional. The ways in which social media was leveraged by these studies included (1) observing adolescent and young adult behavior (n=77), (2) providing health information (n=13), (3) engaging the adolescent and young adult community (n=17), and (4) recruiting research participants (n=23). Common health topics addressed included high-risk sexual behaviors (n=23), alcohol, tobacco, and other drug use (n=19), Internet safety (n=8), mental health issues (n=18), medical conditions (n=11), or other specified issues (n=12). Several studies used more than one social media platform and addressed more than one health-related topic. Conclusions Social media technologies offer an exciting new means for engaging and communicating with adolescents and young adults; it has been successfully used to engage this age group, identify behaviors, and provide appropriate intervention and education. Nevertheless, the majority of studies to date have been preliminary and limited in their methodologies, and mostly center around evaluating how adolescents and young adults use social media and the resulting implications on their health. Although these explorations are essential, further exploration and development of these strategies into building effective interventions is necessary. PMID:25560751

    Background The long-term health consequences of drug use among healthy young adults in the general population are not well described. We assessed whether drug use predicted decline in general self-rated health (GSRH) in a community-based cohort, healthy at baseline. Methods A prospective cohort of 3124 young adults (20-32 years old) from 4 US cities, the Coronary Artery Risk Development in Young Adults Study, was followed from 1987/88 to 2000/01. All reported “Good” or better GSRH at baseline, with reassessment in 2000/01. Drug use in 1987/88 was as follows: 812 participants were Never Users; 1554 Past Users Only; 503 Current Marijuana Users Only; and 255 Current Hard Drug Users (e.g. cocaine, amphetamines, opiates). Analyses measured the association of drug use (1987/88) with decline to “Fair” or “Poor” GSRH in 2000/01, adjusting for biological and psychosocial covariates. Results Reporting health decline were: 7.2% of Never Users; 6.5%, Past Use Only; 7.0%, Current Marijuana Only; and 12.6%, Current Hard Drugs (p<0.01). After multivariable adjustment, Current Hard Drug Use in 1987/88 remained associated with health decline (Odds Ratio (OR), referent Never Use: 1.83, 95% Confidence Interval 1.07-3.12). The health decline associated with Current Hard Drugs appeared to be partly mediated by tobacco smoking in 2000/01, which independently predicted health decline (OR 1.66, 95% CI 1.08-2.50) and weakened the apparent effect of Current Hard Drugs (OR 1.21, 95% CI 0.62-2.36). Conclusions Hard drug use in healthy young adults, even when hard drug use stops, is associated with a subsequent decrease in general self-rated health that may be partially explained by persistent tobacco use.

    During the 1918 influenza pandemic, healthy young adults unusually succumbed to infection and were considered more vulnerable than young children and the elderly. The pathogenesis of this pandemic in the young adult population remains poorly understood. As this population is normally the least likely to die during seasonal influenza outbreaks, thought to be due to their appropriate pre-existing and robust immune responses protecting them from infection, we sought to review existing literature for immunological reasons for excessive mortality during the 1918 pandemic. We propose the novelty of the H1N1 pandemic virus to an H1N1 naïve immune system, the virulence of this virus, and dysfunctional host inflammatory and immunological responses, shaped by past influenza infections could have each contributed to their overall susceptibility. Additionally, in the young adult population, pre-exposure to past influenza infection of different subtypes, such as a H3N8 virus, during their infancy in 1889–1892, may have shaped immunological responses and enhanced vulnerability via humoral immunity effects with cross-reactive or non-neutralizing antibodies; excessive and/or ineffective cellular immunity from memory T lymphocytes; and innate dysfunctional inflammation. Multiple mechanisms likely contributed to the increased young adult mortality in 1918 and are the focus of this review. PMID:26347742

    Posttraumatic epilepsy (PTE) has been modeled with different techniques of experimental traumatic brain injury (TBI) using mice and rats at various ages. We hypothesized that the technique of controlled cortical impact (CCI) could be used to establish a model of PTE in young adult rats. A total of 156 male Sprague-Dawley rats of 2-3 months of age (128 CCI-injured and 28 controls) was used for monitoring and/or anatomical studies. Provoked class 3-5 seizures were recorded by video monitoring in 7/57 (12.3%) animals in the week immediately following CCI of the right parietal cortex; none of the 7 animals demonstrated subsequent spontaneous convulsive seizures. Monitoring with video and/or video-EEG was performed on 128 animals at various time points 8-619 days beyond one week following CCI during which 26 (20.3%) demonstrated nonconvulsive or convulsive epileptic seizures. Nonconvulsive epileptic seizures of >10s were demonstrated in 7/40 (17.5%) animals implanted with 2 or 3 depth electrodes and usually characterized by an initial change in behavior (head raising or animal alerting) followed by motor arrest during an ictal discharge that consisted of high-amplitude spikes or spike-waves with frequencies ranging between 1 and 2Hz class 3-5 epileptic seizures were recorded by video monitoring in 17/88 (19%) and by video-EEG in 2/40 (5%) CCI-injured animals. Ninety of 156 (58%) animals (79 CCI-injured, 13 controls) underwent transcardial perfusion for gross and microscopic studies. CCI caused severe brain tissue loss and cavitation of the ipsilateral cerebral hemisphere associated with cell loss in the hippocampal CA1 and CA3 regions, hilus, and dentate granule cells, and thalamus. All Timm-stained CCI-injured brains demonstrated ipsilateral hippocampal mossy fiber sprouting in the inner molecular layer. These results indicate that the CCI model of TBI in adult rats can be used to study the structure-function relationships that underlie epileptogenesis and PTE. PMID:26432760

    We focus on the potential of social media related to the health of adolescent and young adults, who are nearly ubiquitous social media users but difficult to engage with their health and relatively low healthcare utilizers. Opportunities to better engage adolescents and young adults through social media exist in healthcare delivery, health education and health policy. However, challenges remain for harnessing social media, including making a clear value proposition and developing evidence-based frameworks for measuring the impact of social media on health.

    Over the past decade, new technology and media have changed the way we communicate, access information, and share content with one another. Most 12- to 17-year-olds now own cell phones, and most adolescents and young adults spend several hours per day on computers and cell phones. The American Academy of Pediatrics now encourages all pediatricians to increase their knowledge of new media and technology. This article details technology access among adolescents and young adults, highlights several current and potential innovative applications for new technology and social networking in health promotion, and discusses issues to consider as practitioners move toward integrating new media into clinical and health education settings.

    We investigate the effect of household cash transfers during childhood on young adult body mass indexes (BMI). The effects of extra income differ depending on the household’s initial socioeconomic status (SES). Children from the initially poorest households have a larger increase in BMI relative to children from initially wealthier households. Several alternative mechanisms are examined. Initial SES holds up as the most likely channel behind the heterogeneous effects of extra income on young adult BMI. (JEL D14, H23, H75, I12, J13, J15) PMID:24707346

    This study aimed at assessing the psychosocial adjustment, specifically the emotional distress, quality of life (QOL) and personal growth, in a sample of 36 Portuguese young adults with cancer and 435 healthy controls. Cancer patients scored significantly lower than controls in the role, cognitive and social domains of QOL and in personal growth. Cancer patients scored significantly lower than off-treatment survivors in the role domain of QOL and personal growth. Cancer patients revealed QOL and personal growth difficulties. These issues need to be considered in the psychosocial intervention within adolescents and young adults' oncology care. PMID:24238010

    We examine current perceptions and constraints surrounding condom use among young adults in the Philippines to garner a deeper contextual understanding of this aspect of HIV prevention within Filipino society. Through thematic analysis of focus group data, we found three broad themes, all of which included societal and individual barriers to using condoms. The findings may provide insight for similar settings that have strong religious influences on society. To strengthen HIV prevention efforts in such settings, we suggest that the development of strategies to address these constraints in the cultural setting and promote sexual health of young adults is essential.

    Readers construct mental models of situations described by text. Activity in narrative text is dynamic, so readers must frequently update their situation models when dimensions of the situation change. Updating can be incremental, such that a change leads to updating just the dimension that changed, or global, such that the entire model is updated. Here, we asked whether older and young adults make differential use of incremental and global updating. Participants read narratives containing changes in characters and spatial location and responded to recognition probes throughout the texts. Responses were slower when probes followed a change, suggesting that situation models were updated at changes. When either dimension changed, responses to probes for both dimensions were slowed; this provides evidence for global updating. Moreover, older adults showed stronger evidence of global updating than did young adults. One possibility is that older adults perform more global updating to offset reduced ability to manipulate information in working memory. PMID:25938248

    Word and name retrieval failures increase with age, and this study investigated how priming impacts young and older adults’ ability to produce proper names. The transmission deficit hypothesis predicts facilitation from related prime names, whereas the blocking and inhibition deficit hypotheses predict interference from related names, especially for older adults. On half of our experimental trials, we exposed participants to a prime name that is phonologically- and semantically-related to a target name. Related names facilitated production of targets overall, with older adults’ naming ability improved at least as much as young adults’. Results are contrary to predictions of the blocking and inhibitory deficit hypotheses, and suggest that an activation-based model of memory and language better accounts for retrieval and production of well-known names.

    2015-01-01

    Objective The goal of the present study was to examine whether sexual minority young adults are more vulnerable to developing cardiometabolic risk following exposure to stressful life events than heterosexual young adults. Method Data came from the National Longitudinal Study for Adolescent Health (Shin, Edwards, & Heeren, 2009; Brummett et al., 2013), a prospective nationally representative study of U.S. adolescents followed into young adulthood. A total of 306 lesbian, gay, and bisexual (LGB) respondents and 6,667 heterosexual respondents met inclusion criteria for this analysis. Measures of cumulative stressful life events were drawn from all 4 waves of data collection; sexual orientation and cardiometabolic biomarkers were assessed at Wave 4 (2008–2009). Results Gay/bisexual men exposed to 1–2 (? = 0.71, p = .01) and 5 + (? = 0.87, p = .01) stressful life events had a statistically significant elevation in cardiometabolic risk, controlling for demographics, health behaviors, and socioeconomic status. Moreover, in models adjusted for all covariates, lesbian/bisexual (? = 0.52, p = .046) women with 5 + stressful life events had a statistically significant elevation in cardiometabolic risk. There was no relationship between stressful life events and cardiometabolic risk among heterosexual men or women. Conclusion Stressful life events during childhood, adolescence, and young adulthood place LGB young adults at heightened risk for elevated cardiometabolic risk as early as young adulthood. The mechanisms underlying this relationship require future study. PMID:25133830

    Objective To examine the prevalence of medical conditions and use of health services among young adults with Down syndrome and describe the impact of these conditions upon their lives. Methods Using questionnaire data collected in 2011 from parents of young adults with Down syndrome we investigated the medical conditions experienced by their children in the previous 12 months. Univariate, linear and logistic regression analyses were performed. Results We found that in addition to the conditions commonly experienced by children with Down syndrome, including eye and vision problems (affecting 73%), ear and hearing problems (affecting 45%), cardiac (affecting 25%) and respiratory problems (affecting 36%), conditions also found to be prevalent within our young adult cohort included musculoskeletal conditions (affecting 61%), body weight (affecting 57%), skin (affecting 56%) and mental health (affecting 32%) conditions and among young women menstrual conditions (affecting 58%). Few parents reported that these conditions had no impact, with common impacts related to restrictions in opportunities to participate in employment and community leisure activities for the young people, as well as safety concerns. Conclusion There is the need to monitor, screen and provide appropriate strategies such as through the promotion of healthy lifestyles to prevent the development of comorbidities in young people with Down syndrome and, where present, to reduce their impact.

    Peer victimization leads to negative outcomes such as increased anxiety and depression. The prospective relationship between peer victimization and social anxiety in children and adolescents is well established, and adults with social anxiety disorder (SAD) are more likely than individuals with other anxiety disorders to report a history of teasing. However, a crucial bridge between these findings (peer victimization in young adults) is missing. We manipulated perceptions of peer exclusion in a young adult sample (N=108) using the Cyberball Ostracism Task. Reactivity to exclusion prospectively predicted social anxiety symptoms at a 2-month follow-up, whereas self-reported teasing during high school and current relational victimization did not. This research suggests that reactions to peer victimization may be a worthwhile target for clinical interventions in young adults. Targeting how young adults react to stressful social interactions such as exclusion may help prevent the development of SAD. Future research should test if reactivity to exclusion plays a role in the relationship between other disorders (e.g., depression) and peer victimization. PMID:23768673

    The Herth Hope Index (HHIndex), originally developed for adults, was examined for appropriateness in two studies of adolescents and young adults with cancer-those at various stages of treatment (N = 127) and those newly diagnosed (N = 74). The internal consistency reliability (Cronbach's alpha) of the index was .84 and .78, respectively, in the two samples. Construct validity was supported by discriminant correlations in the moderate to low range between the HHIndex and measures of uncertainty in illness and symptom distress, and by moderate convergent correlations with measures of resilience (self-esteem, self-confidence, and self-transcendence) and quality of life (index of well-being). A four-step factor analysis procedure was done, and confirmatory factor analysis suggested that a one-factor solution best fit the data in this population. Findings indicate that the HHIndex is a reliable measure of hope in adolescents and young adults with cancer. Evidence of discriminant and convergent validity in measuring hope in adolescents and young adults with cancer was also generated. Further exploration of the HHIndex factor structure in adolescents and young adults is needed. PMID:17665817

    Obesity has spread to all segments of the U.S. population. Young adults, aged 18-35 years, are rarely represented in clinical weight loss trials. We conducted a qualitative study to identify factors that may facilitate recruitment of young adults into a weight loss intervention trial. Participants were 33 adults aged 18-35 years with BMI ?25 kg/m(2). Six group discussions were conducted using the nominal group technique. Health, social image, and "self" factors such as emotions, self-esteem, and confidence were reported as reasons to pursue weight loss. Physical activity, dietary intake, social support, medical intervention, and taking control (e.g. being motivated) were perceived as the best weight loss strategies. Incentives, positive outcomes, education, convenience, and social support were endorsed as reasons young adults would consider participating in a weight loss study. Incentives, advertisement, emphasizing benefits, and convenience were endorsed as ways to recruit young adults. These results informed the Cellphone Intervention for You (CITY) marketing and advertising, including message framing and advertising avenues. Implications for recruitment methods are discussed.

    Adolescence is a time of sexual risk-taking and experimentation but also vulnerability. Young people may present to general physicians with systemic symptoms of sexually transmitted infections (STIs), such as arthritis, hepatitis or rash, but may not necessarily volunteer information about sexual activity. It is important for physicians to ask directly about sexual risks and if appropriate test for STIs and pregnancy. Knowing how to take a sexual history and consent a patient for an HIV test are core medical skills that all physicians should be trained to competently perform. Safeguarding young people is the responsibility of all healthcare professionals who come into contact with them, and young victims of abuse may present with physical symptoms such as abdominal pain or deliberate self-harm. We must all be aware of indicators of both child sexual exploitation and HIV infection and not be afraid to ask potentially awkward questions. If we don't we may miss vital opportunities to prevent or minimise harm to young people. PMID:26430183

    Ginsengs are widely used to improve cardiac health and circulation. Loosely termed as ginsengs, Asian (Panax), Siberian and Ashwagandha (Indian Ginseng) Indian ginsengs are prepared from different plants. We tested the popular belief of cardiotonic effects of ginsengs using both neonatal and adult rat cardiomyocytes, comparing extracts from the three ginsengs. Addition of 10% v/v of extract (100 microl of extract/ml of culture medium) of each of the ginsengs resulted in a rapid (<10 s) cessation of beating in neonatal cardiomyocytes due to calcium overload, while sequential dilutions revealed that treatment with a low dose (0.01% v/v, 0.1 microl/ml of the medium) resulted in constant, regular beats (transients), and a slight elevation of diastolic calcium without overload. Addition of extracts to sparking, calcium-tolerant adult cardiomyocytes resulted in initiation of calcium transients, and adult cells were able to tolerate exposure to high concentrations of extract. Cardiotonic effects in adult cells (cardiotoxicity in neonatal cells) were most profound with Asian ginseng (2.6 times that of Siberian ginseng, 1.6 times that of Indian ginseng) probably due to the active ingredients (ginsenosides in Asian, eleutherosides in Siberian and withanolides in Indian) being structurally different. We conclude that fully developed cardiomyocytes are able to accommodate higher doses of ginseng than neonatal cells, and that the effects of ginseng on newly formed, developing myocytes, could be extremely deleterious to the fetus. However, for adults, ginseng might well be a 'tonic' in its ability to increase beating and intramyocytic calcium levels. PMID:16945393

    The organohalides polychlorinated biphenyl (PCB) and polybrominated biphenyl (PBB) remain troublesome environmental pollutants. For example, the percentage of the population in which PCB is detectable in adipose tissue remains high. These compounds are of particular interest to residents of the North Central United States, especially in regions surrounding the Great Lakes where contaminated fish may be a regular component of the diet. Additionally, PBB was mistakenly fed to cattle and chickens in Michigan during the early 1970s, products of which were ingested by humans. Among the physiological effects of ingestion of PCB or PBB is the depression of thyroid status, which has been reported in adult humans, in adult experimental animals, and in the offspring of these animals. In adult rats, circulating levels of thyroid hormones are inversely proportional to dose of PCB or PBB in the diet. On the other hand, reports of effects of these organohalides on adrenocortical function remain equivocal, describing both PCB- and PBB-induced depression, and absence of effect in rats and monkeys. Despite the possible consequences of maternal ingestion of PCB or PBB on future generations, little work has been done previously to determine whether consumption of these materials by pregnant and lactating animals confers hypothyroidism on their offspring, and/or influences other mechanisms of endocrine control in the young. Since early studies showed that hypothyroidism induced by feeding pregnant rats the goitrogen thiouracil altered the functional capabilities in their young of the hypothalamus-pituitary-adrenal (HPA) axis, as revealed by circulating corticosterone levels, the present study was done to determine whether ingestion of either PCB (Aroclor 1254[reg sign]) or PBB (FireMaster BP-6[reg sign]) by pregnant and lactating rats resulted in depressed thyroid status and/or modified HPA axis function in their 15 day old young. 19 refs., 1 fig., 1 tab.

    PubMed Central

    Smeets, Carolina C. J.; Codd, Veryan; Samani, Nilesh J.; Hokken-Koelega, Anita C. S.

    2015-01-01

    Background Subjects born preterm have an increased risk for age-associated diseases, such as cardiovascular disease in later life, but the underlying causes are largely unknown. Shorter leukocyte telomere length (LTL), a marker of biological age, is associated with increased risk of cardiovascular disease. Objectives To compare LTL between subjects born preterm and at term and to assess if LTL is associated with other putative cardiovascular risk factors at young adult age. Methods We measured mean LTL in 470 young adults. LTL was measured using a quantitative PCR assay and expressed as T/S ratio. We analyzed the influence of gestational age on LTL and compared LTL between subjects born preterm (n = 186) and at term (n = 284). Additionally, we analyzed the correlation between LTL and potential risk factors of cardiovascular disease. Results Gestational age was positively associated with LTL (r = 0.11, p = 0.02). Subjects born preterm had shorter LTL (mean (SD) T/S ratio = 3.12 (0.44)) than subjects born at term (mean (SD) T/S ratio = 3.25 (0.46)), p = 0.003). The difference remained significant after adjustment for gender and size at birth (p = 0.001). There was no association of LTL with any one of the putative risk factors analyzed. Conclusions Young adults born preterm have shorter LTL than young adults born at term. Although we found no correlation between LTL and risk for CVD at this young adult age, this biological ageing indicator may contribute to CVD and other adult onset diseases at a later age in those born preterm.

    HPV vaccine uptake in young adult women in the Southern US has been previously found to be the lowest in the country. In addition, geographic variation with regard to HPV vaccination among young adult men has not been investigated yet. The objective of this study was to use the most recent data to determine if inequality still exists. We used Behavioral Risk Factor Surveillance System 2012 data from 8 states (no data available from Midwest) to examine the geographic variations in weighted proportion of adults who initiated (? 1 dose) and completed (3 doses) the HPV vaccine among 3727 young adults (2014 women and 1713 men) 18-26 years old based on self-reported HPV vaccination and socio-demographic characteristics. The weighted vaccine initiation and completion rates among men were: 6.3 and 1.7% overall, 8.5 and 2.2% in the Northeast, 6.7 and 1.6% in the West, and 4.9 and 1.4% in the South (p = 0.184 and 0.774). The rates among women were: 40.4% and 27.4, 58.7 and 45.6%, 39.0 and 24.8%, and 30.4 and 17.7% in the respective regions (p < 0.001 for both). Adjusted multivariable logistic regression showed that women living in the South and West were less likely to initiate and complete the 3-dose HPV vaccine series when compared to those in the Northeast. Despite an increase in HPV vaccine uptake among young adult women in all regions, geographic disparity still exists. Moreover, young adult men had very low HPV vaccine initiation and completion rates throughout the US. PMID:25669443

  11. Rhabdomyosarcoma in adolescent and young adult patients: current perspectives

    PubMed Central

    Egas-Bejar, Daniela; Huh, Winston W

    2014-01-01

    Rhabdomyosarcoma (RMS), a malignant tumor of mesenchymal origin, is the third most common extracranial malignant solid tumor in children and adolescents. However, in adults, RMS represents <1% of all solid tumor malignancies. The embryonal and alveolar histologic variants are more commonly seen in pediatric patients, while the pleomorphic variant is rare in children and seen more often in adults. Advances in the research of the embryonal and alveolar variants have improved our understanding of certain genes and biologic pathways that are involved in RMS, but much less is known for the other variants. Multimodality therapy that includes surgery and chemotherapy with or without radiation therapy is the mainstay of treatment for RMS. Improvements in the risk stratification of the pediatric patients based on presurgical (primary tumor site, tumor size, regional lymph node involvement, presence of metastasis) and postsurgical parameters (completeness of resection or presence of residual disease or metastasis) has allowed for the treatment assignment of patients in different studies and therapeutic trials, leading to increases in 5-year survival from 25%–70% over the past 40 years. However, for adult patients, in great part due to rarity of the disease and the lack of consensus on optimal treatment, clinical outcome is still poor. Many factors have been implicated for the differing outcomes between pediatric RMS versus adult RMS, such as the lack of standardized treatment protocols for adult RMS patients and the increased prevalence of advanced presentations. Now that there are increased numbers of survivors, we can appreciate the sequelae from therapy in these patients, such as bone growth abnormalities, endocrinopathies, and infertility. Improvements in risk stratification have led to clinical trials using lower doses of chemotherapy or radiation therapy with the intention of decreasing the incidence of side effects without compromising survival outcome.
