    The mechanism of a rise in blood pressure after kidney irradiation is unclear but most likely of renal origin. We have investigated the role of the renin-angiotensin system and dietary salt restriction in the development of systolic hypertension after bilateral kidney irradiation in young and adult rats. Three to 12 months after a single X-ray dose of 7.5 or 12.5 Gy to both kidneys of young and adult rats, the systolic blood pressure (SBP) and plasma renin concentration (PRC) were measured regularly. A single X-ray dose of 12.5 Gy caused a moderate rise in SBP and a slight reduction in PRC in both young and adult rats. A dose of 7.5 Gy did not significantly alter the SBP or PRC during the follow-up period of 1 year. In a second experiment, the kidneys of young rats received an X-ray dose of 20 Gy. Subsequently, rats were kept on a standard diet (110 mmol sodium/kg) or a sodium-poor diet (10 mmol sodium/kg). On both diets, SBP started to rise rapidly 3 months after kidney irradiation. Sodium balance studies carried out at that time revealed an increased sodium retention in the irradiated rats compared to controls on the same diet. In rats on a low sodium intake, there was neither a delay nor an alleviation in the development of hypertension. Compared to controls, the PRC tended to be lower in irradiated rats up to 4 months after irradiation. Subsequently, malignant hypertension developed in all 20 Gy rats, resulting in pressure natriuresis, stimulating the renin-angiotensin system. Our findings indicated that hypertension after bilateral kidney irradiation was not primarily the result of an activation of the renin-angiotensin system. Although there were some indications that sodium retention played a role, dietary sodium restriction did not influence the development of hypertension.

    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.

    We determined the acute effects of the angiotension converting enzyme inhibitor captopril on the arterial mechanics in rats at different ages, based on the exponentially tapered T-tube model. Male Wistar-Kyoto rats aged 4 and 12 months were individually referred to as young (n = 8) and adult rats (n = 8) and were anesthetized and thoractomized. The pulsatile aortic pressure and flow signals before and after the administration of captopril (20 mg/kg, i.p.) were measured by a high-fidelity pressure sensor and an electromagnetic flow probe, respectively. In each age group, captopril showed little change in basal heart rate as well as cardiac output. However, captopril produced a drop of 15% in mean aortic pressure in young and a fall of 12% in adult rats. In addition. captopril reduced total peripheral resistance by 21% in young and by 23% in adult animals. As for the pulsatile nature of the arterial system, captopril had increased wave transit time of the lower body circulation of 10% in young and of 12% in adult rats. By contrast, captopril reduced wave reflection factor by 22% in young and by 25% in adult animals. In conclusion, the converting enzyme inhibitor captopril has a stiffness-decreasing effect on Windkessel vessels and a dilated effect on resistance arterioles in either young or adult rats. No age dependence of vascular response and reflex tachycardia to captopril has been found in rats between 4 and 12 months. PMID:11708616

    Targeting mechanisms that result in increased concentrations of kynurenic acid (KYNA) in the brain has been considered as a therapeutic approach for the treatment of epilepsy and certain neurodegenerative disorders. Recently, KYNA has been implicated in the effects produced by the high-fat and low-protein/carbohydrate ketogenic diet (KD) in a report demonstrating an increased production of KYNA in vitro by one of the ketone bodies, ?-hydroxybutyrate, elevated by the KD. To further explore this association, brain concentrations of KYNA were compared in young (3 weeks old) and adult (8-10 weeks old) rats that were chronically exposed to the KD and regular diet. Exposure to the KD resulted in the anticipated elevations of ?-hydroxybutyrate with accompanying decreases in glucose concentrations. In comparison to rats fed the regular diet, KYNA concentrations were significantly (p < 0.05) increased in the hippocampus (256 and 363% increase in young and adult rats, respectively) and in the striatum (381 and 191% increase in young and adult rats, respectively) in KD-fed rats. KD-induced increases in KYNA concentrations in young versus adult rats in the hippocampus and striatum were comparable (p > 0.05). Exposure to the KD had no effect on KYNA concentrations in the cortex of young and adult rats (p > 0.05). In summary, chronic exposure to the KD resulted in several-fold increases in KYNA concentrations in discrete brain structures in the rats. Thus, the relevant clinical question for further exploration is whether KD-induced increases in KYNA concentrations can translate into clinically significant improvements in neuropsychiatric diseases associated with KYNA hypofunction.

    Titanium dioxide nanoparticles (TiO2 NPs) have potential applications as food additives, but concerns persist about their safety. Children are identified as having the highest exposure and may face the greatest health risks. However, the toxicological sensitivity of TiO2 NPs in different ages is not clear. Here, a comparative toxicity study of TiO2 NPs in 3-week (youth) and 8-week (adult) old Sprague-Dawley rats is reported following oral exposure at doses of 0, 10, 50, 200 mg kg(-1) body weight per day for 30 days. The organ mass and histology, blood biochemistry and redox state, intestinal function, and biodistribution of NPs are characterized. The results show that TiO2 NPs induce different toxic effects on young and adult rats. The liver edema, heart injuries and non-allergic mast cell activation in stomach tissues are found in young rats. On the other hand, only slight injury in the liver and kidney and decreased intestinal permeability and molybdenum contents are found in adult rats. Furthermore, TiO2 NP exposure can provoke reductive stress (i.e., increased reduced glutathione (GSH)/oxidized glutathione (GSSG) ratios) in plasmas through enhancing the glucose and GSH levels in young rats or reducing the glutathione peroxidase (GSH-Px) acitivity and GSSG levels in adult rats. These results suggest that different ages may require different biomarkers for identifying and monitoring oral toxicity of nanoparticles. PMID:22945798

    The percutaneous absorption of /sup 14/C-phenoxy ring labeled triadimefon was studied in adult and young male and female Sprague-Dawley rats. Triadimefon was applied (41.1 to 46.4 micrograms/cm2) in 0.2 ml of acetone to areas comprising 3% of the body surface (7.0 to 14.5 cm2). Thirty-six animals were treated at the initiation of each study. Groups of three animals were subsequently killed at 1, 4, 8, 12, 24, 48, 72, 96, 120, 144, 168, and 192 hr after treatment. Skin from the treated area as well as blood, heart, liver, kidneys, remaining carcass, urine, and feces were analyzed for /sup 14/C by scintillation counting techniques. Based on /sup 14/C counts, triadimefon was lost more rapidly from the skin of young animals (t 1/2, 20 to 25 hr) than from the skin of adult animals (t 1/2, 29 to 53 hr). Recovery studies indicated that adult males, adult females, young males, and young females, respectively, absorbed 53, 82, 57, and 52% of the dose. The rest of the dose based on material balance was presumably lost by evaporation. Approximately 2.5 to 3.9% of the dose penetrated the skin in one hour and was available for absorption. The rate of entry triadimefon into blood was 2 to 2.5 times faster for young than that observed in adult animals. Elimination of it from blood was faster in the case of the young animals. Triadimefon was absorbed through the skins of the adult male, adult female, young male, and young female rats, respectively, at rates of 0.20, 0.50, 0.58, and 0.48 micrograms/hr/cm2 of skin.

    To determine whether mature humeral cortical bone would be modified significantly by an acute exposure to weightlessness, adult rats (110 days old) were subjected to 14 days of microgravity on the COSMOS 2044 biosatellite. There were no significant changes in peak force, stiffness, energy to failure, and displacement at failure in the flight rats compared with ground-based controls. Concentrations and contents of hydroxyproline, calcium, and mature stable hydroxylysylpyridinoline and lysylpyridinoline collagen cross-links remained unchanged after spaceflight. Bone lengths, cortical and endosteal areas, and regionl thicknesses showed no significant differences between flight animals and ground controls. The findings suggest that responsiveness of cortical bone to microgravity is less pronounced in adult rats than in previous spaceflight experiments in which young growing animals were used. It is hypothesized that 14 days of spaceflight may not be sufficient to impact the biochemical and biomechanical properties of cortical bone in the mature rat skeleton.

    The hippocampus is important in learning and memory functions but its ability to aid in these functions declines during aging. In this study, we examined hippocampal proteins whose expressions changed in the aging process. A comparison of synaptosome proteins of hippocampus prepared from young-adult (9-week-old) rats with those from aged (30-month-old) rats by two-dimensional fluorescence difference gel electrophoresis revealed 24 spots that were expressed differently among about 1000 spots detected in both young-adult and aged rat samples. Nineteen of these 24 spots were identified by peptide mass fingerprinting. These proteins included chaperone proteins and proteins related to the cytoskeleton, neurotransmission, signal transduction and energy supply. The cytoskeleton-related proteins included actin and T-complex 1, which is thought to play a role in actin folding. Actin was up-regulated but T-complex 1 was down-regulated in aged rat synapses. These results suggest that age-dependent changes of actin filament formation are related to neuronal dysfunction associated with aging. PMID:15911115

    Recent evidence suggests that the behavioral benefits associated with voluntary wheel running in rodents may be due to modulation of glutamatergic transmission in the hippocampus, a brain region implicated in learning and memory. However, the expression of the glutamatergic ionotropic N-methyl-d-aspartate receptor (GluN) in the hippocampus in response to chronic sustained voluntary wheel running has not yet been investigated. Further, the developmental effects during young and mature adulthood on wheel running output and GluN expression in hippocampal subregions has not been determined, and therefore is the main focus of this investigation. Eight-week-old and 16-week-old male Wistar rats were housed in home cages with free access to running wheels and running output was monitored for 4weeks. Wheel access was terminated and tissues from the dorsal and ventral hippocampi were processed for Western blot analysis of GluN subunit expression. Young adult runners demonstrated an escalation in running output but this behavior was not evident in mature adult runners. In parallel, young adult runners demonstrated a significant increase in total GluN (1 and 2A) subunit expression in the dorsal hippocampus (DH), and an opposing effect in the ventral hippocampus (VH) compared to age-matched sedentary controls; these changes in total protein expression were not associated with significant alterations in the phosphorylation of the GluN subunits. In contrast, mature adult runners demonstrated a reduction in total GluN2A expression in the DH, without producing alterations in the VH compared to age-matched sedentary controls. In conclusion, differential running activity-mediated modulation of GluN subunit expression in the hippocampal subregions was revealed to be associated with developmental effects on running activity, which may contribute to altered hippocampal synaptic activity and behavioral outcomes in young and mature adult subjects.

    A sound diagnostic test for Mg deficiency is needed. This is a report of the parenteral Mg load test conducted in weanling and young adult rats fed a purified basal diet containing 3 mg magnesium/100 g with 150 mg of added magnesium/100 g (control) or 0 added magnesium (deficient). Weanlings were studied at about 1 week of dietary treatment and young adults at 2 weeks. The protocol included: a) a 6-hour preload urinary collection; b) an intraperitoneal load of 15 mg of magnesium/kg (weanlings) or 12 mg/kg (young adults) with 2 microCi 28Mg given simultaneously with each load; c) a 6-hour postload urinary collection; d) chemical analysis of selected tissues and urine for Mg; and e) 28Mg counting 6 and 24 hours postload. Controls all excreted large amounts of Mg pre- and postload, retaining less than 26% of nonradioactive loads. They had high urinary 28Mg counts. In Mg-deficient animals, the concentration of Mg in bone more than halved. These animals avidly conserved Mg and retained over 85% of nonradioactive Mg loads. Their 28Mg activity in vital organs was 3--6 times greater than in controls. We concluded that the parenteral Mg load test reliably identifies severe Mg deficiency.

    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

    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 (14-18 months of age) and 14 young adult (2.5-6.5 months of age) female rats after performance of a high repetition low force (HRLF) reaching and grasping task for 12 weeks. 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 (4 reaches/min) and required submaximal pulling force (30 force-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 12 weeks, with increased inflammatory cytokine responses and osteoclast activity as possible causes.

    Nitrate has described as an endocrine disruptor that promotes onset of diabetes. This study was undertaken to evaluate diabetic effect of high nitrate intake in young and adult male rats and its amelioration by fenugreek administration. The study revealed significant increase in serum glucose and blood glycosylated hemoglobin (HbA1c%), while serum insulin and liver glycogen were decreased among nitrate exposed animals, in particular the young group. A significant reduction in the body weight gain and serum thyroid hormones (T4 & T3) was also recorded. Further reduction in serum levels of urea and creatinine, as well as total protein in serum, liver and pancreas was demonstrated, with elevation in their levels in the urine of all nitrate exposed groups. Meanwhile, the activity of serum transaminases (ALT and AST) was increased, with decline in their activity in the liver tissue. In addition, an elevation in serum total bilirubin, tissues (liver and pancreas) nitric oxide and lipid profile, as well as liver activity of glucose-6-phosphatase was recorded. Fenugreek administration to nitrate exposed rats was found to be effective in alleviating hyperglycemia and other biochemical changes characterizing nitrate-induced diabetes. So, fenugreek can be considered to possess potent activity against onset of nitrate induced-diabetes. PMID:24615531

    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 α/β (TRα/β) 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.

    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.

    Adolescents and adults may respond differently to antidepressants, with poorer efficacy and greater probability of adverse effects in adolescents. The mechanisms underlying this differential response are largely unknown, but likely relate to an interaction between the neural effects of antidepressants and brain development. We used Fos immunohistochemistry to examine regional differences in adolescent (postnatal day (PND) 28) and young adult (PND 56) male, Wistar rats given a single injection of the selective serotonin reuptake inhibitor paroxetine (10mg/kg). Paroxetine induced widespread Fos expression in both adolescent and young adult rats. Commonly affected areas include the bed nucleus of the stria terminalis (dorsolateral), medial preoptic area, paraventricular hypothalamic and thalamic nuclei and central nucleus of the amygdala. Fos expression was generally lower in adolescents with significantly greater Fos expression observed in young adults in the prelimbic cortex, supraoptic nucleus, basolateral amygdala, lateral parabrachial and Kölliker-Fuse nuclei. However, a small subset of regions showed greater adolescent Fos expression including the nucleus accumbens shell, lateral habenula and dorsal raphe. Paroxetine increased plasma corticosterone concentrations in young adults, but not adolescents. Plasma paroxetine levels were not significantly different between the age groups. These results indicate a different c-Fos signature of acute paroxetine in adolescent rats, with greater activation in key mesolimbic and serotonergic regions, but a more subdued cortical, brainstem and hypothalamic response. This suggests that the atypical response of adolescents to paroxetine may be related to a blunted neuroendocrine response, combined with insufficient top-down regulation of limbic regions involved in reward and impulsivity.

    Penetration of 2,4,5,2{prime},4{prime},5{prime}-({sup 14}C)hexachlorobiphenyl (HCB) through skin of young (33 days) and adult (82 days) female Fischer 344 rats was determined in vivo and by two in vitro methods. In vivo dermal penetration at 120 hr was 45% in young and 43% in adults. At 72 hr in vivo dermal penetration was 35% in young and 26% in adults compared to 1.5% for young and 1.0% for adult as measured with a continuous flow in vitro system and 2.9% for young and 1.9% for adults as measured with a static in vitro system. Most of the dermally absorbed HCB remained in the body as only 4.9 and 2.6% of that absorbed was excreted by young and adult rats, respectively, at the end of 120 hr. Significant differences in dermal penetration and kinetics of HCB between young and adult female rats were observed. The elimination of ECB-derived material was approximately six times higher in feces than in urine. A physiological pharmacokinetic model was fitted to the organ and tissue radioactivity distribution data. Parameters in the model determined from dermal dosing of female Fischer 344 rats were in reasonable agreement with those reported in the literature for adult male Sprague-Dawley rats (iv dose). The rate constant for dermal penetration was 0.83 {times} 10{sup {minus}4} min{sup {minus}1} for adults and 0.96 {times} 10{sup {minus}4} min{sup {minus}1} for young. The delay or lag time parameter for dermal penetration was 4.4 hr in adults and 1.1 hr in young.

    Irreversible cognitive deficits induced by ethanol exposure during fetal life have been ascribed to a lower NMDA-dependent synaptic long-term potentiation (LTP) in the hippocampus. Whether NMDA-dependent long-term depression (LTD) may also play a critical role in those deficits remains unknown. Here, we show that in vitro LTD induced with paired-pulse low frequency stimulation is enhanced in CA1 hippocampus field of young adult rats exposed to ethanol during brain development. Furthermore, single pulse low frequency stimulation, ineffective at this age (LFS600), induced LTD after ethanol exposure accompanied with a stronger response than controls during LFS600, thus revealing an aberrant form of activity-dependent plasticity at this age. Blocking NMDA receptor or GluN2B containing NMDA receptor prevented both the stronger response during LFS600 and LTD whereas Zinc, an antagonist of GluN2A containing NMDA receptor, was ineffective on both responses. In addition, LFS600-induced LTD was revealed in controls only with a reduced-Mg(2+) medium. In whole dissected hippocampus CA1 field, perinatal ethanol exposure increased GluN2B subunit expression in the synaptic compartment whereas GluN2A was unaltered. Using pharmacological tools, we suggest that LFS600 LTD was of synaptic origin. Altogether, we describe a new mechanism by which ethanol exposure during fetal life induces a long-term alteration of synaptic plasticity involving NMDA receptors, leading to an aberrant LTD. We suggest this effect of ethanol may reflect a delayed maturation of the synapse and that aberrant LTD may also participates to long-lasting cognitive deficits in fetal alcohol spectrum disorder.

    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 in vivo genotoxicity of CI Solvent Yellow 14 (Sudan I) was examined using repeated-dose liver and gastrointestinal tract micronucleus (MN) assays in young adult rats. Sudan I is a mono-azo dye based on aniline and 1-amino-2-hydroxynaphthalene. This dye was demonstrated as a rat liver carcinogen in a National Toxicology Program (NTP) bioassay, and genotoxicity was noted in a rat bone marrow micronucleus (BMMN) assay. In the present study, Sudan I was administered orally to rats for 14-days, and the MN frequency in the liver, stomach, colon, and bone marrow were analyzed. The frequency of micronucleated hepatocytes (MNHEPs) was not significantly increased by the administration of the Sudan I. Gastrointestinal tract MNs were also not induced. However, in the BMMN assay, a significant increase in micronucleated immature erythrocytes (MNIMEs) was observed in a dose-dependent manner. While Sudan I has been reported to lack hepatic genotoxicity, it has also exhibited tumor-promoting activities. These results are consistent with the lack of induction of MN in the hepatocytes. The lack of MN induction in cells of the gastrointestinal tract was also logical because azo-compounds are reported to be unlikely to induce DNA damage in the rat gut. The repeated-dose rat liver and gastrointestinal tract MN assays have the potential to be used in the evaluation of the genotoxicity of a chemical in each organ in accordance with its mode of action.

    Young adult (60 day old) Wistar rats of either sex were orally intubated with 50 mg/kg body weight and 100 mg/kg body weight of aqueous root extract of Clitoria ternatea (CTR) for 30 days, along with age-matched saline controls. These rats were then subjected to passive avoidance tests and the results from these studies showed a significant increase in passive avoidance learning and retention. Subsequent to the passive avoidance tests, these rats were killed by decapitation. The amygdala was processed for Golgi staining and the stained neurons were traced using a camera lucida and analysed. The results showed a significant increase in dendritic intersections, branching points and dendritic processes arising from the soma of amygdaloid neurons in CTR treated rats especially in the 100 mg/kg group of rats, compared with age-matched saline controls. This improved dendritic arborization of amygdaloid neurons correlates with the increased passive avoidance learning and memory in the CTR treated rats as reported earlier. The results suggest that Clitoria ternatea aqueous root extract enhances memory by increasing the functional growth of neurons of the amygdala. PMID:16161034

    Background Isoflurane exposure causes improvement in long-term neurocognitive function in young adult rats, this is associated with an increase in dentate gyrus progenitor proliferation 4 days after anesthesia. However, the number of new neurons, that were born from cells that incorporated bromodeoxyuridine 4 days after anesthesia is not affected by anesthesia. We tested the hypothesis that progenitor proliferation continues to increase past 4 days, which would imply the possibility that the number of new neurons after anesthesia could be increased if bromodeoxyuridine labeling occurred at a later time point. Methods Bromodeoxyuridine was injected at 0, 1, 2, 4, 9, 16 days after 4 hours of isoflurane exposure to 60-day old rats. Brains were harvested 2 hours later, immunohistochemically stained, and the number of bromodeoxyuridine-positive cells in the dentate gyrus was assessed microscopically. Results After 4 hours of exposure to isoflurane in 60-day old rats, the number of bromodeoxyuridine-positive cells decreased on days 02, then increased on day 4 significantly, and regressed toward the control level on day 9 and 16. Conclusions Anesthesia-induced progenitor proliferation in the dentate gyrus was not sustained 9 days after anesthesia. We interpret these results to signify that an anesthetic effect on neurogenesis likely does not play a critical role in the previously observed isoflurane-induced long-term improvement in neurocognitive function in 60-day old rats and that the transient increase in progenitor proliferation serves to replenish the pool of neural stem cells. The mechanism of anesthesia-induced improvement in cognition of young adult rats remains elusive. PMID:23752046

    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.

    Hypertension remains a major societal problem affecting 76 million, or approximately one third, of US adults. While more prevalent in the older population, an increasing incidence in the younger population, including athletes, is being observed. Active individuals, like the young and athletes, are viewed as free of diseases such as hypertension. However, the increased prevalence of traditional risk factors in the young, including obesity, diabetes mellitus, and renal disease, increase the risk of developing hypertension in younger adults. Psychosocial factors may also be contributing factors to the increasing incidence of hypertension in the younger population. Increased left ventricular wall thickness and mass are increasingly found in young adults on routine echocardiograms and predict future cardiovascular events. This increasing incidence of hypertension in the young calls for early surveillance and prompt treatment to prevent future cardiac events. In this review we present the current epidemiological data, potential mechanisms, clinical implications, and treatment of hypertension in young patients and athletes. PMID:26821528

    Abstract Previous studies have shown that the change of cerebral metabolic rate of glucose (CMRglc) in response to traumatic brain injury (TBI) is different in young (PND35) and adult rats (PND70), and that prolonged ketogenic diet treatment results in histological and behavioral neuroprotection only in younger rat brains. However, the mechanism(s) through which ketones act in the injured brain and the biochemical markers of their action remain unknown. Therefore, the current study was initiated to: 1) determine the effect of injury on the neurochemical profile in PND35 compared to PND70 rats; and 2) test the effect of early post-injury administration of ketogenic diet on brain metabolism in PND35 versus PND70 rats. The data show that alterations in energy metabolites, amino acid, and membrane metabolites were not evident in PND35 rats on standard diet until 24?h after injury, when the concentration of most metabolites was reduced from sham-injured values. In contrast, acute, but transient deficits in energy metabolism were measured at 6?h in PND70 rats, together with deficits in N-acetylaspartate that endured until 24?h. Administration of a ketogenic diet resulted in significant increases in plasma ?-hydroxybutyrate (?OHB) levels. Similarly, brain ?OHB levels were significantly elevated in all injured rats, but were elevated by 43% more in PND35 rats compared to PND70 rats. As a result, ATP, creatine, and phosphocreatine levels at 24?h after injury were significantly improved in the ketogenic PND35 rats, but not in the PND70 group. The improvement in energy metabolism in the PND35 brains was accompanied by the recovery of NAA and reduction of lactate levels, as well as amelioration of the deficits of other amino acids and membrane metabolites. These results indicate that the PND35 brains are more resistant to the injury, indicated by a delayed deficit in energy metabolism. Moreover, the younger brains revert to ketones metabolism more quickly than do the adult brains, resulting in better neurochemical and cerebral metabolic recovery after injury. PMID:21635175

    Maternal protein restriction (MPR) during pregnancy is associated with increased cardiovascular risk in the offspring in adulthood. In this study we evaluated the cardiac function of young male rats born from mothers subjected to MPR during pregnancy, focusing on the myocardial mechanics and calcium-handling proteins. After weaning, rats received normal diet until 3 mo old, when the following parameters were assessed: arterial and left ventricular hemodynamics and in vitro cardiac contractility in isolated papillary muscles. The body weight was lower and arterial pressure higher in the MPR group compared with young adult offspring of female rats that received standard diet (controls); and left ventricle time derivatives increased in the MPR group. The force developed by the cardiac muscle was similar; but time to peak and relaxation time were longer, and the derivatives of force were depressed in the MPR. In addition, MPR group exhibited decreased post-pause potentiation of force, suggesting reduced reuptake function of the sarcoplasmic reticulum. Corroborating, the myocardial content of SERCA-2a and phosphorylated PLB-Ser16/total PLB ratio was decreased and sodium-calcium exchanger was increased in the MPR group. The contraction dependent on transsarcolemmal influx of calcium was higher in MPR if compared with the control group. In summary, young rats born from mothers subjected to protein restriction during pregnancy exhibit changes in the myocardial mechanics with altered expression of calcium-handling proteins, reinforcing the hypothesis that maternal malnutrition is related to increased cardiovascular risk in the offspring, not only for hypertension, but also cardiac dysfunction.

    Few studies have assessed the effects of developmental methylmercury (MeHg) exposure on learning and memory at different ages. The possibility of the amelioration or worsening of the effects has not been sufficiently investigated. This study aimed to assess whether low-dose MeHg exposure in utero and during suckling induces differential disturbances in learning and memory of periadolescent and young adult rats. Four experimental groups of pregnant Sprague-Dawley rats were orally exposed to MeHg or vehicle from gestational day 5 to weaning: (1) control (vehicle), (2) 250 μg/kg/day MeHg, (3) 500 μg/kg/day MeHg, and (4) vehicle, and treated on the test day with MK-801 (0.15 mg/kg i.p.), an antagonist of the N-methyl D-aspartate receptor. The effects were evaluated in male offspring through the open field test, object recognition test, Morris water maze, and conditioned taste aversion. For each test and stage assessed, different groups of animals were used. MeHg exposure, in a dose-dependent manner, disrupted exploratory behaviour, recognition memory, spatial learning, and acquisition of aversive memories in periadolescent rats, but alterations were not observed in littermates tested in young adulthood. These results suggest that developmental low-dose exposure to MeHg induces age-dependent detrimental effects. The relevance of decreasing exposure to MeHg in humans remains to be determined.

    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

    Increasing epidemiological and toxicological evidence suggests that pesticides and other environmental exposures may be associated with the development of Parkinson's disease (PD). Chlorpyrifos (CPF) is a widely used organophosphorous pesticide with developmental neurotoxicity. Its neurotoxicity, notably on the monoamine system, suggests that exposure of CPF may induce dopaminergic neuronal injury. We investigated whether neonatal exposure to CPF contributes to initiation and progression of dopaminergic neurotoxicity and explored the possible underlying mechanisms. The newborn rats were administrated 5 mg/kg CPF subcutaneously from postnatal day (PND) 11 to PND 14 daily. The effect of CPF on dopaminergic neurons, microglia, astrocyte, nuclear factor-?B (NF-?B) p. 65 and p. 38 mitogen-activated protein kinase (MAPK) signaling pathways was analyzed in the substantia nigra of rats at 12h, 24h, 72 h, 16d and 46 d after exposure. CPF-treated rats exhibited significant reduction of dopaminergic neurons at 16d and 46 d after exposure, and a significant increase in the expression of microglia and astrocytes in the substantia nigra after CPF exposure. Intense activation of NF-?B p. 65 and p. 38 MAPK inflammatory signaling pathways was observed. Our findings indicate that neonatal exposure to CPF may induce long-term dopaminergic neuronal damage in the substantia nigra mediated by the activation of inflammatory response via NF-?B p. 65 and p. 38 MAPK pathways in the nigrostriatal system.

    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

    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

    1. Ochratoxin A (OTA) is a mycotoxin produced by several fungi, especially Aspergillus and Penicillium species. Many food and foodstuffs can be contaminated by ochratoxin A, which is consequently found in blood of animals and humans. 2. The distribution into the brain of young adult rats fed OTA for 1 to 6 weeks and some consequences have been investigated in the present study. 3. Our results on rats given OTA (289 microg/kg/48 h) indicated that OTA accumulated in the whole brain as function of time according to a regression curve, Y=-8.723 a+16.72 with a correlation coefficient of r=0.989, where Y-axis is the OTA concentration in ng/g of brain and X-axis is the duration of the treatment in weeks. The brain OTA contents was 11.95 +/- 2.2, 23.89 +/- 4.4, 39.9 +/- 4.5, 50.3 +/- 7.3, 78.8 +/- 6.3, 94 +/- 16 ng/g of brain in the mycotoxin-treated animals for respectively 1, 2, 3, 4, 5 and 6-weeks treatment. OTA induced modifications of free amino-acid concentrations in the brain, mainly, Tyrosine (Tyr) and phenylalanine (Phe). Tyr decreased significantly as compared to control (p < 0.05). Phe increased significantly as compared to control (p < 0.05). 4. Aspartame, (25 mg/kg/48 h) a structural analogue of OTA largely modified the distribution and prevented the accumulation of OTA in the brain since the respective brain OTA contents decreased respectively to 9.6 +/- 7.9, 19.2 +/- 3.0, 26.8 +/- 4.2, 19.7 +/- 1.9, 13.7 /- 5.6 and 11.0 +/- 6.0 ng/g of tissue, for the same duration of treatment. It also prevented the modifications of Tyr and Phe levels. 5. The histological investigations showed several necrotic cells with pyknotic nucleus, detected in OTA treated animals with higher frequency as compared to the controls and Aspartame treated ones. Aspartame appeared to significantly prevent this nuclear effect as well, the meaning of which is discussed. PMID:9726534

    Steroid hormones are important players to regulate adult neurogenesis in the dentate gyrus of the hippocampus, but their involvement in the regulation of the same phenomenon in the subventricular zone (SVZ) of the lateral ventricles is not completely understood. Here, in male rats, we tested the existence of activational effects of testosterone (T) on cell proliferation in the adult SVZ. To this aim, three groups of male rats: castrated, castrated and treated with T, and controls were treated with 5-bromo-2'-deoxyuridine (BrdU) and killed after 24h. The density of BrdU-labeled cells was significantly lower in castrated animals in comparison to the other two groups, thus supporting a direct correlation between SVZ proliferation and levels of circulating T. To clarify whether this effect is purely androgen-dependent, or mediated by the T metabolites, estradiol (E2) and dihydrotestosterone (DHT), we evaluated SVZ proliferation in castrated males treated with E2, DHT and E2+DHT, in comparison to T- and vehicle-treated animals, and sham-operated controls. The stereological analysis demonstrated that E2 and T, but not DHT, increase proliferation in the SVZ of adult male rats. Quantitative evaluation of cells expressing the endogenous marker of cell proliferation phosphorylated form of Histone H3 (PHH3), or the marker of highly dividing SVZ progenitors Mash1, indicated the effect of T/E2 is mostly restricted to SVZ proliferating progenitors. The same experimental protocol was repeated on ovariectomized female rats treated with E2 or T. In this case, no statistically significant difference was found among groups. Overall, our results clearly show that the gonadal hormones T and E2 represent important mediators of cell proliferation in the adult SVZ. Moreover, we show that such an effect is restricted to males, supporting adult neurogenesis in rats is a process differentially modulated in the two sexes. PMID:25481234

    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.

  4. Different types of soluble fermentable dietary fibre decrease food intake, body weight gain and adiposity in young adult male rats

    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

    The normal number and arrangement of motoneurons contributing fibres, via the median and radial nerves, to the forearm muscles of the rat were determined at different stages of postnatal development. Horseradish peroxidase was applied directly to the proximal cut ends of the nerves in 5, 10, 21 days old and adult rats. At each stage of development, the motoneuronal pool for each nerve was confined to the ipsilateral, dorsolateral area of Lamina IX. In general, median nerve motoneurons were found dorsal and medial to those of the radial nerve and were located between the rostral parts of the C6-T1 segments of the spinal cord. The radial nerve motoneuronal pool extended between the caudal end of the C4 and rostral tip of the T1 segment. There was considerable overlap between the two populations, especially along the dorsoventral axis. Counts of labelled motoneurons revealed that significantly fewer were present in adult compared to 5 days old rats (P less than 0.05 for each nerve). Approximately 50% of the motoneurons were lost from each nerve over this period. Although results from other studies suggest that part of the apparent loss may have been due to deficiencies in the HRP tracing technique, the possibility of motoneuronal death cannot be entirely excluded in this study.

    Although increasing consumption of sugar drinks is recognized as a significant public health concern, little is known about (a) the cognitive effects resulting from sucrose consumption; and (b) whether the long-term effects of sucrose consumption are more pronounced for adolescents. This experiment directly compared performance on a task of spatial learning and memory (the Morris Water Maze) and sensitivity to outcome devaluation following 28 days of 2-h/day access to a 10% sucrose solution in adolescent and young-adult Wistar rats. Sucrose groups developed elevated fasting blood glucose levels after the diet intervention, despite drawing <15% of calories from sucrose and gaining no more weight than controls. In subsequent behavioral testing, sucrose groups were impaired on the Morris Water Maze, with some residual deficits in spatial memory observed more than 6 weeks after the end of sucrose exposure. Further, results from outcome devaluation testing indicated that in the older cohort of rats, those fed sucrose showed reduced sensitivity to devaluation of the outcome, suggestive of differences in instrumental learning following sucrose exposure. Data provide strong evidence that sucrose consumption can induce deficits in spatial cognition and reward-oriented behavior at levels that resemble patterns of sugar drink consumption in young people, and which can remain long after exposure.

    The repeated-dose liver micronucleus (RDLMN) assay has the potential to detect liver carcinogens and can be integrated into general toxicological studies. In this study, thioacetamide (TAA) was tested in 14- and 28-day RDLMN assays to assess the performance of the assay. The test substance, TAA, was administered orally to 6-week-old male Crl:CD (SD) rats once daily for 14 or 28 days at a dosage of 5, 10 or 20mg/kg/day. Hepatocytes were collected approximately 24h after the last TAA administration, and the incidence of micronuclei was assessed. In this study, bone marrow micronucleus assays were also conducted in the same animals. The 14- and 28-day RDLMN assays indicated that none of the TAA dosages significantly increased the proportion of micronucleated hepatocytes. Bone marrow micronucleus assays with TAA also provided negative results. It is known that TAA is a liver carcinogen in mice and rats. In the previous genotoxic studies, the Ames test and the chromosomal aberration test using CHL/IU cells have yielded negative results [1-4]. The liver micronucleus assay using young adult rats singly dosed with TAA (75 and 150mg/kg) also produced negative results [5]. TAA gave positive results only in the mouse bone marrow micronucleus assays [6,7]. PMID:25892627

    Rationale Previous studies in rodents show that early exposure to methylphenidate alters later responsiveness to drugs of abuse. An interesting feature of these studies is that early methylphenidate treatment decreases the rewarding value of cocaine when measured by conditioned place preference (CPP), but the same treatment increases cocaine self-administration. Objective The goal of the present study was to examine the effects of early methylphenidate exposure on cocaine-induced responding using both reward paradigms. Methods Rats were treated with methylphenidate (0, 2, or 5 mg/kg) from postnatal day (PD) 11 to PD 20 and then cocaine-induced CPP or cocaine self-administration was measured in separate groups of rats in adulthood. The CPP procedure included eight days of acquisition training, eight days of extinction training, and a reinstatement test. Rats were conditioned with 0, 10 or 20 mg/kg cocaine. Reinstatement was assessed after a priming dose of cocaine (10 mg/kg). For the self-administration experiment, a jugular catheter was implanted and rats were trained to press a lever reinforced with cocaine (0.25 or 0.75 mg/kg/infusion) on a fixed ratio (FR) 1 schedule. Rats were gradually moved from an FR1 to an FR10 schedule and, after criterion was reached, rats were placed on a progressive ratio schedule for five days. Results Cocaine produced robust rewarding effects as determined by both the CPP and self-administration experiments; however, early methylphenidate exposure only enhanced the reinforcing effects of cocaine on the self-administration paradigm. Interestingly, this methylphenidate enhancement was only seen in male rats. Conclusions These data suggest that in males methylphenidate enhances the reinforcing value of cocaine, but not cocaine-associated cues. PMID:20848087

    The present study was designed to examine the effect of exercise on femoral neck bone structure and strength in female rats after 4 and 10 months of exercise. Female Fischer rats aged 2 months were exercised for 4 h a day, 5 days a week on a motor-driven treadmill the speed of which was gradually increased until a daily distance of 2 km was reached. The training level was maintained for 4 months (n = 15) and 10 months (n = 15). Sedentary age-matched rats served as controls (n = 30). At death the proximal third of both femora was obtained from each rat. The left femoral neck was tested in a materials-testing machine, and the right was used for either trabecular bone mass measurement (BV/TV) or scanning electron microscopy (SEM). Biomechanical testing revealed a significant training-induced increase in femoral neck bone strength after 4 months of exercise, which although not accelerated was preserved after 10 months of exercise. Histologic investigation revealed a significant training-induced increase in BV/TV, accounted for by a significantly smaller proportion of marrow space. No difference in cortical area was found. Both histology and SEM revealed a tendency to an earlier closure of the growth line in the exercised animals. However, the exercised animals aged 6 months had a significantly increased total femoral length compared with the sedentary rats. No difference was found in total femoral length between sedentary and exercised rats aged 12 months. On the basis of this study, it is concluded that exercise has a positive effect on femoral neck bone strength.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8191936

    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), {gamma}-glutamylcysteine synthetase ({gamma}-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 1 g/kg) in corn oil. Four hours later, frontal cortex, cerebellum, striatum, and hippocampus were dissected, quick frozen on dry ice, and stored at - 80 Degree-Sign 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 12 month 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.

    Clinical and experimental evidence suggest that estrogens have a major impact on cognition, presenting neurotrophic and neuroprotective actions in regions involved in such function. In opposite, some studies indicate that certain hormone therapy regimens may provoke detrimental effects over female cognitive and neurological function. Therefore, we decided to investigate how estrogen treatment would influence cognition and depression in different ages. For that matter, this study assessed the effects of chronic 17β-estradiol treatment over cognition and depressive-like behaviors of young (3 months old), adult (7 months old) and middle-aged (12 months old) reproductive female Wistar rats. These functions were also correlated with alterations in the serotonergic system, as well as hippocampal BDNF. 17β-Estradiol treatment did not influence animals' locomotor activity and exploratory behavior, but it was able to improve the performance of adult and middle-aged rats in the Morris water maze, the latter being more responsive to the treatment. Young and adult rats displayed decreased immobility time in the forced swimming test, suggesting an effect of 17β-estradiol also over such depressive-like behavior. This same test revealed increased swimming behavior, triggered by serotonergic pathway, in adult rats. Neurochemical evaluations indicated that 17β-estradiol treatment was able to increase serotonin turnover rate in the hippocampus of adult rats. Interestingly, estrogen treatment increased BDNF levels from animals of all ages. These findings support the notion that the beneficial effects of 17β-estradiol over spatial reference memory and depressive-like behavior are evident only when hormone therapy occurs at early ages and early stages of hormonal decline.

    Moderate reduction in dietary protein composition of pregnant rats from 25% to 8% casein, calorically compensated by carbohydrates, has been described as a "hidden malnutrition" because it does not alter body and brain weights of pups at birth. However, this dietary treatment leads to altered central noradrenergic systems, impaired cortical long-term potentiation (LTP) and worsened visuo-spatial memory performance. Given the increasing interest on the role played by ?2-adrenoceptors (?2-ARs) on brain plasticity, the present study aimed to address the following in hidden-malnourished and eutrophic control rats: (i) the expression levels of ?2-ARs in the frontal cortex determined by immunohistochemistry, and (ii) the effect of the ?2 selective agonist clenbuterol on both LTP elicited in vivo in the prefrontal cortex and visuospatial performance measured in an eight-arm radial maze. Our results showed that, prenatally malnourished rats exhibited a significant reduction of neocortical ?2-AR expression in adulthood. Concomitantly, they were unable to elicit and maintain prefrontal cortex LTP and exhibited lower visuospatial learning performance. Administration of clenbuterol (0.019, 0.038 and 0.075 mg/kg i.p.) enhanced LTP in malnourished and control animals and restored visuospatial learning performance in malnourished but not in normal rats, in a dose-dependent manner. The results suggest that decreased density of neocortical ?2-ARs during postnatal life, subsequent to hidden prenatal malnutrition might affect some synaptic networks required to elicit neocortical LTP and form visuospatial memory, since those neuroplastic deficits were counteracted by ?2-AR stimulation.

    Heightened impulsivity is a feature of some psychiatric disorders, including addiction, that also have sex-specific patterns of expression. The relationship between addiction and impulsivity may be driven by drug-induced changes in behavior caused by long term adaptations in signaling within the medial prefrontal cortex (mPFC). Here, we used a response inhibition task that is sensitive to changes in mPFC function to examine the effects of sex and exposure to amphetamine (AMPH) on impulsive action and vigilance. We also examined drug-induced alterations in glutamatergic and dopaminergic signaling through challenge injections with the NMDA receptor antagonist MK-801 (dizocilpine) and AMPH. Male and female Sprague Dawley rats were injected (i.p.) with saline or 3 mg/kg AMPH every other day during adolescence (postnatal day (P) 2745) or adulthood (P85103). Starting on P125135, rats were tested for their ability to lever press for a food reward during periods of signaled availability and withhold responding during a premature response phase. In experiment 1, rats received challenge injections (i.p.) of MK-801 and AMPH followed by tests of task performance and locomotor activity. In experiment 2, rats received intra-mPFC infusion of MK-801. We found that females had better inhibitory control and poorer vigilance than males and that AMPH exposure had both sex- and age-of-exposure dependent effects on impulsivity. Systemic drug challenges disrupted task performance, particularly in females, and increased impulsivity while intra-mPFC infusions had modest effects. AMPH exposure did not affect responses to drug challenges. Together, these results suggest that sex mediates both trait and drug-induced impulsivity. PMID:24462963

    Marriage is widely thought to confer mental health benefits, but little is known about how this apparent benefit may vary across the life course. Early marriage, which is nonnormative, could have no, or even negative, mental health consequences for young adults. Using survey data from waves 1 and 3 of the National Longitudinal Study of Adolescent Health (n = 11,695), I find that married young adults exhibit levels of psychological distress that are similar to those of young adults in any kind of romantic relationship. Married and engaged young adults also report lower frequency of drunkenness than those who are not in a romantic relationship. Married young adults, especially those who first married at ages 22 to 26, report higher life satisfaction than those in other type of romantic relationships,those in no romantic relationship, and those who married prior to age 22. Explanations for these findings are examined, and their implications are discussed. PMID:22328171

    Young adulthood is a time of immense growth and possibilities. As a result, it is also a time when serious illness can have profound effects. This review examines the current data pertinent to young adult palliative care and discusses the challenges and opportunities where palliative medicine can enhance the care provided to this growing and vulnerable population. From the data, 2 primary themes emerged (1) ongoing young adult development not only generates unique biologic disease burdens and clinical treatment options but also requires frequent assessment and promotion and (2) binary health care systems often leave young adults without access to developmentally appropriate health care. Given its interdisciplinary approach, palliative care is uniquely poised to address the challenges known to caring for the seriously ill young adult. PMID:24198063

    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.

    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.

    Age is a significant factor in modifying specific needs when it comes to medical aesthetic procedures. In this review we will focus on young adults in their third decade of life and review minimally invasive aesthetic procedures other than cosmetics and cosmeceuticals. Correction of asymmetries, correction after body modifying procedures, and facial sculpturing are important issues for young adults. The implication of aesthetic medicine as part of preventive medicine is a major ethical challenge that differentiates aesthetic medicine from fashion. PMID:21673871

    Flu vaccines are partially protective in infants and elder people. New adjuvants such as immunostimulatory oligonucleotides (ODNs) are strong candidates to solve this problem, because a combination with several antigens has demonstrated effectiveness. Here, we report that IMT504, the prototype of a major class of immunostimulatory ODNs, is a potent adjuvant of the influenza vaccine in young adult and elderly rats. Flu vaccines that use virosomes or whole viral particles as antigens were combined with IMT504 and injected in rats. Young adult and elderly animals vaccinated with IMT504-adjuvated preparations reached antibody titers 20-fold and 15-fold higher than controls, respectively. Antibody titers remained high throughout a 120 day-period. Animals injected with the IMT504-adjuvated vaccine showed expansion of the anti-hemagglutinin antibody repertoire and a significant increase in the antibody titer with hemagglutination inhibition capacity when confronted to viral strains included or not in the vaccine. This indicates that the addition of IMT504 in flu vaccines may contribute to the development of significant cross-protective immune response against shifted or drifted flu strains. PMID:21793787

    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

  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

  2. Mechanisms of L-triiodothyronine-induced inhibition of synaptosomal na(+)-k(+)-ATPase activity in young adult rat brain cerebral cortex.

    2013-01-01

    The role of thyroid hormones (TH) in the normal functioning of adult mammalian brain is unclear. Our studies have identified synaptosomal Na(+)-K(+)-ATPase as a TH-responsive physiological parameter in adult rat cerebral cortex. L-triiodothyronine (T3) and L-thyroxine (T4) both inhibited Na(+)-K(+)-ATPase activity (but not Mg(2+)-ATPase activity) in similar dose-dependent fashions, while other metabolites of TH were less effective. Although both T3 and the β -adrenergic agonist isoproterenol inhibited Na(+)-K(+)-ATPase activity in cerebrocortical synaptosomes in similar ways, the β -adrenergic receptor blocker propranolol did not counteract the effect of T3. Instead, propranolol further inhibited Na(+)-K(+)-ATPase activity in a dose-dependent manner, suggesting that the effect of T3 on synaptosomal Na(+)-K(+)-ATPase activity was independent of β -adrenergic receptor activation. The effect of T3 on synaptosomal Na(+)-K(+)-ATPase activity was inhibited by the α2-adrenergic agonist clonidine and by glutamate. Notably, both clonidine and glutamate activate Gi-proteins of the membrane second messenger system, suggesting a potential mechanism for the inhibition of the effects of TH. In this paper, we provide support for a nongenomic mechanism of action of TH in a neuronal membrane-related energy-linked process for signal transduction in the adult condition. PMID:24307963

  3. Reducing Underage and Young Adult Drinking

    2010-01-01

    Forty years ago, when the National Institute on Alcohol Abuse and Alcoholism (NIAAA) was founded, alcoholism was considered an adult disease driven principally by physiological determinants. As NIAAA expanded its research portfolio, new data and insights were obtained that led to an increased focus on underage and young adult drinking. Fostered by interdisciplinary research, etiologic models were developed that recognized the multiplicity of relevant genetic and environmental influences. This shift in conceptualizing alcohol use disorders also was based on findings from large-scale, national studies indicating that late adolescence and early young adulthood were peak periods for the development of alcohol dependence and that early initiation of alcohol use (i.e., before age 15) was associated with a fourfold increase in the probability of subsequently developing alcohol dependence. In recent years, developmental studies and models of the initiation, escalation, and adverse consequences of underage and early young adult drinking have helped us to understand how alcohol use may influence, and be influenced by, developmental transitions or turning points. Major risk and protective factors are being identified and integrated into screening, prevention, and treatment programs to optimize interventions designed to reduce drinking problems among adolescents and young adults. In addition, regulatory policies, such as the minimum drinking age and zero-tolerance laws, are being implemented and evaluated for their impact on public health. PMID:23579934

    To extend our previous experiment on anti-glucocorticoid effects of melatonin which was performed under a very special condition using young rats, we have carried out another experiment of long term administration of pineal hormone melatonin to adult female rats which were conditioned by overdose glucocorticoid. The results clearly demonstrated significant protection, by melatonin, from the injurious effects of a glucocorticoid, dexamethasone: decrease of body weight gain, atrophy of the thymus and adrenals, and elevation of the level of total cholesterol in blood. Thus, it has been clarified that anti-glucocorticoid effects of melatonin could be shown experimentally not only in young rats but also in adults, and also, could be really seen not only in short term experiment but also in longer ones. Anti-glucocorticoid effects of melatonin seem to be of considerably wide range, not being limited to occur under a special condition, including the age of animals, in experiments. PMID:3661196

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.

    2001-08-01

    Measles outbreaks in Victoria in 1999 and 2001 have suggested that a substantial proportion of young Victorian adults may be susceptible to measles infection. We performed a serosurvey of 300 18-30-year-old healthy blood donors and 312 sera retrieved after diagnostic testing for a non-rash illness in patients of the same age group, with the aim of estimating the proportion of young adults in Victoria immune to measles. We also aimed to define more precisely the birth cohorts at risk of measles infection, with cohorts reflecting the measles immunisation policies of previous years. There was no significant difference in measles immunity between the 300 blood donors (79.0%, 95% confidence interval 73.9-83.5) and the 312 patients whose sera had been stored (84.0%, 95% CI 79.4-87.9, p=0.11). There was, however, a significant difference in immunity by birth cohort. In the combined results from both samples, the proportion of people born between 1968 and 1974 who were immune to measles was 88.4 per cent (95% CI 84.1-91.6) while the proportion of those born between 1975 and 1981 was 74.1 per cent (95% CI 68.7-79.1). This study confirms that a substantial proportion of young Victorian adults are susceptible to measles, but also demonstrates that those born between 1975 and 1981 are more likely to be non-immune than those born before 1975. A review of published Australian data supports this conclusion and confirms the need for a measles control program aimed at young adults. PMID:11596714

  20. Informal Mentoring and Young Adult Employment

    PubMed Central

    2007-01-01

    This study explores the role of informal mentoring (i.e., developing an important relationship with a non-parental adult) in the transition to full time employment among young adults (age 23-28). Multivariate analysis of the Add Health data reveals that mentoring is positively related to the likelihood of full time employment, and the relationship involves both selection and causation processes. Entrance into the world of work facilitates the development of mentoring relationships, especially among youth who identify work-related mentors after adolescence. These relationships have the potential for promoting attachment to the labor force. Mentoring relationships that develop outside of work settings and during adolescence have a positive impact on the odds of full time employment. The receipt of guidance and advice from mentors, as well as access to weak-tied mentoring relationships, teacher mentors, and friend mentors all contribute to the increased odds of employment in young adulthood. However, adolescent mentoring may be less effective among young women than it is among young men. PMID:19050736

    The pharmacokinetics of caffeine were studied in young (age: 1 day, 7 days, 14 days, 30-45 days) and adult dogs following a single intravenous dose of 50 mg/kg. Mean (+/-SE) plasma elimination half life (T1/2) was 47.5 (+/-5.35) h in 1-day-old puppies, as opposed to 6.66(+/-0.85) h in adult dogs. A rapid decrease in plasma T1/2 values occurred during the first 2 weeks of life. At about 14 days of age caffeine plasma T1/2 was similar to that of adults. The volume of distribution was greatest (0.94+/- 0.03 liters/kg) and the total body clearance was smaller (2.81 +/- 0.73 liters/kg/min X 10(-4)) in the 1-day-old animals. The much smaller body clearance of caffeine in the newborn as compared to the adult dog could be due to a lower rate of metabolism and/or renal excretion of this drug in the young. PMID:603798

    1985-06-01

    Uninstitutionalized young adults with chronic mental disorders and social disabilities pose a new challenge in community psychiatry. These attention-seeking, help-rejecting young men and women spend most of their lives in the community and differ markedly from older deinstitutionalized chronic psychiatric patients. Many confound identification by their abuse of drugs and/or alcohol. Most deny their mental illness and make inappropriate use of mental health services available to them. Because of the different problems and aspirations of these patients compared to older chronic patients, treatment programs must be age segregated to address these differences. Young adult chronic patients are best helped via flexible, accessible, nonstigmatizing, team-oriented treatment programs. Some patients require long-term neuroleptic therapy at low maintenance doses. In addition to their role as the primary provider of psychiatric care to these patients, psychiatrists must act as advisors to families and community planners and as political activists to focus additional attention on community-based (rather than state hospital-oriented) programs.

    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

    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.

    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 nave rats mild NMDAR blockade by low-dose memantine improves working memory related to a highly challenging task. PMID:24385956

    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.

    Ischemic stroke is rare in young adults, but it is genuinely a serious situation giving the fact that it touch a very active part of our society. We report a series of 128 cases. The purpose is to analyze the risk factors, etiologies and outcomes of ischemic stroke in young adults in Marrakesh. Retrospective study performed at the Neurology department Mohammed VI universitary hospital in Marrakesh interesting 128 patients. The diagnosis of ischemic stroke was assessed through clinical and radiological confrontation. Results: The age of our patients varied from 18 to 45 years old, 76 males and 52 females giving a male: female ratio of 1:46. Hypertension was the first risk factor involved with 63 (49.2%) cases, followed by smoking with 52 (40.6%) patients. The causes of ischemic stroke were characterized by the predominance of the cardio embolic origin with 43 (33.5%) cases, the existence of 14 (11%) cases of syphilitic arthritis, and the 52 (40.6%) cases of unknown etiologies. The authors stress the difficulties faced on supporting ischemic stroke in southern Morocco in particular when concerned by the etiological finding and the rehabilitation after the acute phase of the stroke. Our study points out the high incidence of embolic heart disease in our context. The lack of neurologists, low coverage of the population and the underestimation by physicians are factors that can explain why ischemic stroke remain undiagnosed. PMID:24932348

    Objective Develop a burn injury model in young age rats. Background Management of pain after burn injury in pediatric patients is an unresolved clinical issue. Methods A burn injury model in young rats of 34 weeks old was developed by briefly immersing the dorsal part of the right hindpaw in a hot water bath (85C) for 12 seconds under pentobarbital anesthesia. Results Burn injury, but not sham control, induced nociceptive behaviors (mechanical allodynia, thermal hyperalgesia) when examined on post-injury day 2, 4 and 7. In burn-injured rats, there was the upregulated expression of the NR1 subunit of the N-methyl-d- aspartate (NMDA) receptor, Akt1, Akt2, and protein kinase C ? (PKC ?), but downregulated expression of neuronal nitric oxide synthase (nNOS), inducible NOS (iNOS), and glycogen synthase kinase-3? (GSK-3?), within the spinal cord dorsal horn ipsilateral to burn injury. Moreover, intraperitoneal administration of a clinically available NMDA receptor antagonist dextromethorphan (30 mg/kg, once daily 7 days beginning on day 7 after burn injury) attenuated mechanical allodynia and thermal hyperalgesia in burn-injured rats. Different from our previous finding in adult burn-injured rats, however, burn injury in young rats of this age did not spontaneously shift the morphine antinociceptive response curve to the right within the dose range used in the study when exposed to morphine for the first time, suggesting that the development of intrinsic tolerance to morphine antinociception may be different from adult rats following burn injury. Conclusions Our data suggest that this model may be used to explore the mechanisms of burn injury-induced nociception in young rats and to differentiate the sequelae from burn injury between adult and young rats under certain experimental conditions.

    PubMed

    Gupta, Ruchi S

    2014-01-01

    It is critical that clinicians treating young adults understand the presentation and management of anaphylaxis. The most common trigger for anaphylaxis in this population is food. The prevalence of food allergy is growing, with 8% of US children and adolescents affected. All patients at risk for anaphylaxis should be prescribed epinephrine autoinjectors, as epinephrine is the only life-saving medication for a severe anaphylactic reaction. The presentation of anaphylaxis can involve multiple organ systems (eg, mucocutaneous, respiratory, cardiovascular, gastrointestinal) and, as such, patient education is needed to assist in prompt recognition. Appropriate training of patients and caregivers about how to identify anaphylaxis and what to do in an emergency is critical. Training of school and college staff also is essential, as 1 in 4 first-time reactions occurs outside the home. Additional counseling for adolescents at risk for anaphylactic reactions should address increased risk-taking behavior, decreased adult supervision, dating, and the transition of disease management from an adult to the patient.

    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.

    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

    The purpose of this study was to investigate factors associated with substance use among homeless young adults. Multinomial logistic regression analyses examined the influence of social networks and economic factors among a group of homeless young adults with differing levels of alcohol and drug use. In addition, for those with an alcohol use disorder, the role of future time expectancies was examined. A sample (n = 185) of homeless young adults aged 18 to 23 were recruited from a community drop-in center and interviewed utilizing self-report instruments. Findings suggest that social networks, economic factors, and future expectancies are significant predictors of the level of substance use among homeless young adults. Being able to identify those areas that place homeless young adults at risk for substance abuse and dependence has implications for effective intervention. PMID:20391267

    Risk factors for marijuana use in older adolescents and young adults have focused primarily on family environment and peer affiliation. A growing body of work has examined the relationship between environmental context and young adult substance use. This study builds on previous research linking neighborhood environment to young adult marijuana use by exploring two distinct features of neighborhoods, namely the physical (e.g. broken windows) and social environment (e.g. adults watching youth). Data were obtained from a longitudinal sample of 398 predominately African American young adults living in an urban environment. The data also included observational measures of physical and social order and disorder collected on the young adult's residential block. Exploratory structural equation modeling (ESEM) was utilized to test hypothesized relationships between these two features of the neighborhood environment and past year young adult marijuana use. A two-factor model of neighborhood environment with good fit indices was selected (CFI=0.97, RMSEA=0.037). There was a positive and significant direct effect from neighborhood physical disorder to marijuana use (0.219, p<0.05) controlling for gender, race, and free and reduced meals status. The direct effect from neighborhood social environment to marijuana use was not significant. These results converge with previous research linking vacant housing with young adult marijuana use but do not provide empirical support for the neighborhood social environment as a determinant of drug taking. Better explication of the social environment is needed to understand it's relationship to drug use. PMID:25005818

    Context Approximately 22% of U.S. young adults (aged 1824 years) are smokers.1 Young adults typically display an interest in quitting,1,2 but it is unknown whether the evidence-based cessation programs designed for adults will be equally effective for young adults. Purpose This meta-analysis investigated the efficacy of smoking-cessation programs for this population. Evidence acquisition In 20092011, studies published between 2004 and 2008 that investigated smoking cessation were first found through the DHHS Clinical Practice Guidelines for Treating Tobacco Use and Dependence3 as well as a PubMed search (20092010) and were then subjected to a rigorous inclusion process. Authors were contacted to glean young adult raw data. Fourteen studies provided data that were coded for descriptive information and aggregated using the Comprehensive Meta-Analysis Version 2.04. Evidence synthesis Among young adults, any type of intervention was more effective in producing successful smoking cessation than the control. This was the case for intent-to-treat analyses as well as complete cases. When interventions were effective for the larger adult sample, they were also effective for the younger adult sample. Conclusions While young adults tend to underutilize evidence-based cessation treatments, the current meta-analysis showed that these treatments should be as effective for young adults as they are for the general adult population. Thus, it may be useful to focus on motivating young adults to seek cessation treatment to increase utilization. PMID:22608385

    Investigating social participation of young adults with an autism spectrum disorder (ASD) is important given the increasing number of youth aging into young adulthood. Social participation is an indicator of life quality and overall functioning. Using data from the National Longitudinal Transition Study 2, we examined rates of participation in social activities among young adults who received special education services for autism (ASD group), compared to young adults who received special education for intellectual disability, emotional/behavioral disability, or a learning disability. Young adults with an ASD were significantly more likely to never see friends, never get called by friends, never be invited to activities, and be socially isolated. Among those with an ASD, lower conversation ability, lower functional skills, and living with a parent were predictors of less social participation. PMID:23615687

    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

    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

    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.

    Peripheral nerve injury promotes an enduring increase in the excitability of the spinal dorsal horn. This change, that likely underlies the development of chronic pain, may be a consequence of prolonged exposure of dorsal horn neurons to mediators such as neurotrophins, cytokines, and neurotransmitters. The long-term effects of such mediators can be analyzed by applying them to spinal neurons in organotypic slice culture. To assess the validity of this approach, we established serum-free, defined-medium organotypic cultures (DMOTC) from E13-14 prenatal rats. Whole-cell recordings were made from neurons maintained in DMOTC for up to 42 days. These were compared with recordings from neurons of similar age in acute spinal cord slices from 15- to 45-day-old rats. Five cell types were defined in acute slices as 'Tonic', 'Irregular', 'Delay', 'Transient' or 'Phasic' according to their discharge patterns in response to depolarizing current. Although fewer 'Phasic' cells were found in cultures, the proportions of 'Tonic', 'Irregular', 'Delay', and 'Transient' were similar to those found in acute slices. GABAergic, glycinergic, and 'mixed' inhibition were observed in neurons in acute slices and DMOTC. Pure glycinergic inhibition was absent in 7d cultures but became more pronounced as cultures aged. This parallels the development of glycinergic inhibition in vivo. These and other findings suggest that fundamental developmental processes related to neurotransmitter phenotype and neuronal firing properties are preserved in DMOTC. This validates their use in evaluating the cellular mechanisms that may contribute to the development of chronic pain. PMID:16516387

    Increased levels of neurotoxic amyloid-beta in the brain are a prominent feature of Alzheimers 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 l amyloid-beta(2535) 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(2535) 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(2535) 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 knowledge of the spatial distribution and the local concentration of trace elements in tissues are of great importance since trace elements are involved in a number of metabolic and physiological processes in the human body, and their deficiency and excess may lead to different metabolic disorders. In this way, the main goal of this work is to compare the elemental concentration in different brain structures, namely temporal cortex, entorhinal cortex, visual cortex and hippocampus, from Wistar female rats ( n = 15) with different ages: 2, 8 and 48 weeks. The measurements were performed at the Synchrotron Light Brazilian Laboratory, Campinas, São Paulo, Brazil. In the entorhinal cortex, the following elements decreased with age: Zn, S, Cl, K, Ca and Br. In the temporal cortex, Ca, Fe and Br levels increased with aging and on the other hand, P, S, Cl, K and Rb levels decreased with aging. In the visual cortex almost all the elements decreased with aging: Cl, Ca, Fe, Ni and Zn. In the hippocampus, in turn, most of the elements identified, increased with aging: Al, P, S, K, Fe, Cu, Zn and Rb. The increase of Fe with aging in the hippocampus is an important fact that will be studied, since it is involved in oxidative stress. It is believed that oxidative stress is the one of the main causes responsible for neuronal death in Parkinson's disease.

  9. The neurotrophin receptor p75NTR mediates early anti-inflammatory effects of estrogen in the forebrain of young adult rats

    Background Estrogen suppresses microglial activation and extravasation of circulating monocytes in young animals, supporting an anti-inflammatory role for this hormone. However, the mechanisms underlying estrogen's anti-inflammatory effects, especially in vivo, are not well understood. The present study tests the hypothesis that anti-inflammatory effects of estrogen are mediated by the pan-neurotrophin receptor p75NTR. Previously, we reported that estrogen attenuated local increases of interleukin(IL)-1β in the NMDA-lesioned olfactory bulb, while further increasing NGF expression. Results The present studies show that this lesion enhances expression of the neurotrophin receptor p75NTR at the lesion site, and p75NTR expression is further enhanced by estrogen treatment to lesioned animals. Specifically, estrogen stimulates p75NTR expression in cells of microvessels adjacent to the lesion site. To determine the role of this receptor in mediating estrogen's anti-inflammatory effects, a p75NTR neutralizing antibody was administered at the same time the lesion was created (by stereotaxic injections of NMDA) and specific markers of the inflammatory cascade were measured. Olfactory bulb injections of NMDA+vehicle (preimmune serum) increased IL-1β and activated the signaling molecule c-jun terminal kinase (JNK)-2 at 6 h. At 24 h, the lesion significantly increased matrix metalloproteinase (MMP)-9 and prostaglandin (PG)E2, a COX-2 mediated metabolite of arachadonic acid. All of these markers were significantly attenuated by estrogen in a time-dependent manner. However, estrogen's effects on all these markers were abolished in animals that received anti-p75NTR. Conclusion These data support the hypothesis that estrogen's anti-inflammatory effects may be, in part, mediated by this neurotrophin receptor. In view of the novel estrogen-dependent expression of p75NTR in cells associated with microvessels, these data also suggest that the blood brain barrier is a critical locus of estrogen's neuro-immune effects.

    The origins of the obesogenic environment date back to the early 1980s. This means that young adults i.e., those aged 18 to 35 years, have only ever experienced a food milieu that promotes obesity. Indeed, younger generations are becoming heavier sooner than their parents in developed countries, such as the USA. Young adults demonstrate food consumption patterns and dietary behaviors implicated in an excessive gain of body fat. They are the highest consumers of fast food and sugar-sweetened beverages among adult age groups and the lowest consumers of fruit and vegetables. Younger adults are meal skippers but may consume more energy from snacks than older adults. So that the gains made in stemming obesity in childhood are not undone during young adulthood, prevention programs are needed. This review highlights areas for consideration in planning such programs. PMID:26811006

  3. Environmental sustainability: Understanding young adults' learning, thinking, and actions

    Kola-Olusanya, Anthony O.

    This thesis explores the ways in which young-adults' environmental learning and experiences influence their decision to live sustainably. In particular, this thesis focuses on young adults' environmental and sustainability learning. It elaborates on young peoples' views about environmental and sustainability issues, such as climate change, the sources for their learning about these issues, and how young adults' learning encounters, in turn, affect their actions toward environmental protection and decision-making. Through a series of in-depth individual interviews with 18 young adults from three universities in southeastern Ontario, this qualitative study provides in-depth insight into young adults' understanding, learning experiences, and actions in relation to environmental and sustainability issues. Employing a Contextual Model of Learning framework the narratives of the young adults in this study are analyzed and discussed within three overlapping environmental learning contexts: personal, sociocultural, and physical settings. This framework allows for an examination of the complex interactions and relationships that shape how and where environmental learning occurs. The findings in this study suggest that the three overlapping learning contexts, that is the personal, sociocultural, and physical play an important role in shaping young adults' learning about environmental and sustainability issues. The data reveal that despite the unavailability or near-absence of environmental studies and education within the formal school curriculum (particularly at the elementary and high school levels), the young adults rely on other locations for learning, such as the internet, environmental non-governmental organisations (ENGOs), television, and family. In light of this, the research participants suggest the re-introduction of environmental programs and content in the school curriculum. Finally, the results of this study demonstrate the centrality of knowledge and experience in relation to environmental and sustainability issues in the actions and thoughts of the young adult research participants. This study makes an important contribution to the field of environmental and sustainability education by demonstrating the critical role of learning in a knowledge society. It illuminates the implications of various learning contexts for a sustainable global environment and future.

    Adolescent and young adult cancer survivors face unique challenges not systematically addressed by cancer clinicians. Four focus groups and two individual interviews were conducted with 19 survivors to profile experiences and identify key concerns for future interventions. The resultant themes reflect cancer care continuum challenges (such as delays in diagnosis, problems with adherence), psychosocial concerns (such as infertility and reproductive concerns, changing social relationships, financial burden), and the paradox of being diagnosed with cancer as a young adult. Future intervention development for adolescent and young adult survivors should involve patient voices at each stage of the research process. PMID:22416959

    Risk factors for marijuana use in older adolescents and young adults have focused primarily on family environment and peer affiliation. A growing body of work has examined the relationship between environmental context and young adult substance use. This study builds on previous research linking neighborhood environment to young adult marijuana use by exploring two distinct features of neighborhoods, namely the physical (e.g., broken windows) and social environment (e.g., adults watching youth). Data were obtained from a longitudinal sample of 398 predominately African American young adults living in an urban environment. The data also included observational measures of physical and social order and disorder collected on the young adult's residential block. Exploratory structural equation modeling (ESEM) was utilized to test hypothesized relationships between these two features of the neighborhood environment and past year young adult marijuana use. A two-factor model of neighborhood environment with good fit indices was selected (CFI = 0.97, RMSEA = 0.037). There was a positive and significant direct effect from neighborhood physical disorder to marijuana use (0.219, p < 0.05) controlling for gender, race, and free and reduced price meal (FARPM) status. The direct effect from neighborhood social environment to marijuana use was not significant. These results converge with previous research linking vacant housing with young adult marijuana use but do not provide empirical support for the neighborhood social environment as a determinant of drug taking. Better explication of the social environment is needed to understand its relationship to drug use. PMID:25005818

    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

    Effects of hippocampal lesions and aging on spatial learning and memory and ameliorating effects of red ginseng on learning deficits were investigated in the following two experiments: performance of young rats with selective hippocampal lesions with red ginseng by mouth (p.o.; Experiment 1) and aged rats with red ginseng (p.o.; Experiment 2) in the spatial tasks was compared with that of sham-operated or intact young rats. Each rat in these two behavioral experiments was tested with the three types of spatial-learning tasks (distance movement task, DMT; random-reward place search task, RRPST; and place-learning task, PLT) in a circular open field using intracranial self-stimulation as reward. The results in the DMT and RRPST tasks indicated that motivational and motor activity of young rats with hippocampal lesions with and without ginseng were not significantly different from that of sham-operated young rats in Experiment 1. However, young rats with hippocampal lesions displayed significant deficits in the PLT task. Treatment with red ginseng significantly ameliorated place-navigation deficits in young rats with hippocampal lesions on the PLT task. Similarly, red ginseng improved performance of aged rats on the PLT task in Experiment 2. The results, along with previous studies showing significant effects of red ginseng on the central nervous system, suggest that red ginseng ameliorates learning and memory deficits through effects on the central nervous system, partly through effects on the hippocampal formation.

    African mole-rats (family Bathyergidae) are small to medium sized, long-lived, and strictly subterranean rodents that became valuable animal models as a result of their longevity and diversity in social organization. The formation and integration of new hippocampal neurons in adult mammals (adult hippocampal neurogenesis, AHN) correlates negatively with age and positively with habitat complexity. Here we present quantitative data on AHN in wild-derived mole-rats of 1 year and older, and briefly describe its anatomical context including markers of neuronal function (calbindin and parvalbumin). Solitary Cape mole-rats (Georychus capensis), social highveld mole-rats (Cryptomys hottentotus pretoriae), and eusocial naked mole-rats (Heterocephalus glaber) were assessed. Compared to other rodents, the hippocampal formation in mole-rats is small, but shows a distinct cytoarchitecture in the dentate gyrus and CA1. Distributions of the calcium-binding proteins differ from those seen in rodents; e.g., calbindin in CA3 of naked mole-rats distributes similar to the pattern seen in early primate development, and calbindin staining extends into the stratum lacunosum-moleculare of Cape mole-rats. Proliferating cells and young neurons are found in low numbers in the hippocampus of all three mole-rat species. Resident granule cell numbers are low as well. Proliferating cells expressed as a percentage of resident granule cells are in the range of other rodents, while the percentage of young neurons is lower than that observed in surface dwelling rodents. Between mole-rat species, we observed no difference in the percentage of proliferating cells. The percentages of young neurons are high in social highveld and naked mole-rats, and low in solitary Cape mole-rats. The findings support that proliferation is regulated independently of average life expectancy and habitat. Instead, neuronal differentiation reflects species-specific demands, which appear lower in subterranean rodents. PMID:24904308

    Objective: This investigation examined patterns of heavy drinking among Black and White young adults from a person-centered perspective and linked family and individual factors in adolescence to young adult drinking patterns. Method: The analysis focuses on 331 10th-grade students (168 Whites, 163 Blacks; 51% males) who were followed into young adulthood (ages 20 and 22). Cluster analyses using heavy episodic drinking, drunkenness, and alcohol problems in young adulthood resulted in groups of drinkers with different patterns. Groups were examined across and within race. Associations between young adult drinking groups and adolescent family and individual factors were tested. Results: Groups followed well-established race differences, with Whites clustering into frequent drinking groups more than Blacks, and Blacks clustering into nonheavy drinking groups more than Whites. Further, Black heavy drinkers reported fewer alcohol problems than White counterparts. Parental monitoring, consistent discipline, ethnic identity, and delinquency were associated with adult heavy episodic drinking groups for both races. Monitoring and delinquency, along with parental norms, were associated with drunkenness groups for both races. However, race differences were observed for drunkenness clusters such that attachment was predictive for White clusters, and parental guidelines and discipline were predictive for Black clusters. Conclusions: Large race differences in heavy drinking at young adulthood were confirmed. Family dynamics in 10th grade were identified as important for the development of different drinking patterns in the early 20s, when many individuals have left home, which suggests a key target for substance use prevention programs.

    Objectives Lack of work-participation and early disability pensions (DP's) among young adults are increasing public health problems in most western European countries. The present study investigated determinants of early DP in young adults in vocational rehabilitation. Methods Data from 928 young adults (aged 18-40 years) attending a vocational rehabilitation program was linked to DP's recorded in the Norwegian Labor and Welfare Organization registries (1992-2010) and later compared to a group of 65 employees (workers). We used logistic regression to estimate the odds ratio for entitlement to DP following rehabilitation, adjusting for socio-demographical, psychosocial and health-behavior factors. Results Significant differences in socio-demographical, psychosocial and health-behavior factors were found between the rehabilitation group and workers. A total of 60 individuals (6.5 %) were granted a DP during follow-up. Increase in age, teenage parenthood, single status, as well as low education level and not being employed were found to be the strongest independent determinants of DP. Conclusion Poor social relations (being lone), early childbearing and weak connection to working life contributed to increase in risk of DP's among young adults in vocational rehabilitation, also after adjusting for education level. These findings are important in the prevention of early disability retirements among young adults and should be considered in the development of targeted interventions aimed at individuals particularly at risk of not being integrated into future work lives.

    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

    Little is known about how older persons determine if someone deserves their trust or not based on their facial appearance, a process referred to as facial trustworthiness.In the past few years, Todorov and colleagues have argued that, in young adults, trustworthiness judgments are an extension of emotional judgments, and therefore, that trust judgments are made based on a continuum between anger and happiness (Todorov, 2008; Engell et al., 2010). Evidence from the literature on emotion processing suggest that older adults tend to be less efficient than younger adults in the recognition of negative facial expressions (Calder et al., 2003; Firestone et al., 2007; Ruffman et al., 2008; Chaby and Narme, 2009). Based on Todorov';s theory and the fact that older adults seem to be less efficient than younger adults in identifying emotional expressions, one could expect that older individuals would have different representations of trustworthy faces and that they would use different cues than younger adults in order to make such judgments. We verified this hypothesis using a variation of Mangini and Biederman's (2004) reverse correlation method in order to test and compare classification images resulting from trustworthiness (in the context of money investment), from happiness, and from anger judgments in two groups of participants: young adults and older healthy adults. Our results show that for elderly participants, both happy and angry representations are correlated with trustworthiness judgments. However, in young adults, trustworthiness judgments are mainly correlated with happiness representations. These results suggest that young and older adults differ in their way of judging trustworthiness. PMID:24046755

One crisis line is operated by a major suicide prevention center; the second is a crisis help line for adolescents that offers peer counselors. Adults and young adults reported depression as the primary reason for contemplating suicide; adolescents reported interpersonal problems. Despite the chronic nature of the presenting problems, referrals were provided to fewer than one-half of the adults and young adults and fewer than one-third of the adolescent callers. Although the callers reported suicide ideation, a very small percentage fell into the high-risk categories with regard to degree of suicide planfulness and lethality of chosen method. PMID:8362278

    Adolescent homelessness has received increasing attention due to its fast growth throughout the United States and the poor mental outcomes experienced by homeless young people. This cross-sectional study (N = 156) identified correlates of depressive symptomatology among homeless young adults and investigated how depressive symptoms are influenced by the coping strategies these young adults employ. The findings are based on analysis of baseline data collected for a hepatitis vaccination intervention pilot study conducted in partnership with a young adult’s drop-in center in Santa Monica, California. Standardized tools assessed drug use history, coping ability, and psychiatric symptomatology. Linear regression modeling was used to identify correlates of depressive symptom severity. Poor perceived physical health, recent crack cocaine use and recent use of tranquilizers were significantly associated with increased severity of depressive symptoms. Self-destructive escape, non-disclosure/avoidance, passive problem-solving and thoughts of harming self were also associated with increased severity of depressive symptoms. PMID:21131507

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).

    In January 2001 a 19-year-old Sydney resident, who had recently returned from India, visited Melbourne for 4 days while infectious with measles. A further 50 measles cases were subsequently identified, mainly among young adults. Thirty-eight cases (75%) were in the same birth cohort (born between 1968 and 1981). This cohort was identified as being at high risk of measles infection after a previous outbreak in Victoria involving 75 cases. These individuals are now aged between 20 and 33 years. A high proportion of cases, 22 (43%) were hospitalised after multiple visits to various healthcare providers. None of the cases had documentation of receiving the recommended number of doses of measles-containing vaccine for their age. Repeated outbreaks clearly demonstrate that young adults remain the group at highest risk of measles infection in Victoria. More targeted strategies for young adults and healthcare workers are required to better protect these groups against measles. PMID:12206382

Methods The sample included 210 inner-city young adults (18 to 25 years) recruited from the Atlanta, Georgia, USA. Results Respondents who indicated greater fear of their neighborhood environment also had significantly greater levels of drug use than did those with lower perceived fear. However, this relationship was not a result of lower self-esteem or higher levels of depressive symptoms. Conclusions Exploratory results point to the need to consider the broader role of the community environment and its impact on drug use among young adults. PMID:19182981

Minimal evidence regarding treatment effectiveness of renovascular comorbidities in youth with early onset T2D is available, due to the relatively recent emergence of T2D in youth and young adults. Extrapolation of adult therapy guidelines is not an ideal approach to making therapeutic decisions in this population. Evolving management and intervention strategies are based on accumulating longitudinal data from cohorts of well characterized youth and young adults with T2D. The degree of similarity in histologic findings and disease specific characteristics of kidney disease in patients with early onset T2D and albuminuria compared to affected adults is not well characterized. Early aggressive therapies to minimize the impact of nephropathy are indicated as the evidence for best therapies in youth with T2D are further explored. PMID:24398660

The degree of similarity in histologic findings and disease specific characteristics of kidney disease in patients with early onset T2D and albuminuria compared with affected adults is not well characterized. Early aggressive therapies to minimize the impact of nephropathy are indicated as the evidence for best therapies in youth with T2D are further explored. PMID:24398660

  1. A Complementary Alternative Medicine Questionnaire for Young Adults

    PubMed Central

    Patterson, Christine; Arthur, Heather

    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

  2. Effects of β-adrenergic receptor agonists on drinking and arterial blood pressure in young and old rats

    PubMed Central

    Grobe, Connie L.; Beltz, Terry G.; Johnson, Alan Kim

    2011-01-01

    These experiments examined water-drinking and arterial blood pressure responses to β-adrenergic receptor activation in young (4 mo), “middle-aged” adult (12 mo), and old (29 mo) male rats of the Brown-Norway strain. We used isoproterenol to simultaneously activate β1- and β2-adrenergic receptors, salbutamol to selectively activate β2-adrenergic receptors, and the combination of isoproterenol and the β2-adrenergic receptor antagonist ICI 118,551 to stimulate only β1-adrenergic receptors. Animals received one of the drug treatments, and water drinking was measured for 90 min. About 1 wk later, animals received the same drug treatment for measurement of arterial blood pressure responses for 90 min. In some rats, levels of renin and aldosterone secretion in response to isoproterenol or salbutamol were measured in additional tests. Old and middle-aged rats drank significantly less after isoproterenol than did young rats and also had greater reductions in arterial blood pressure. Old and middle-aged rats drank significantly less after salbutamol than did young rats, although reductions in arterial blood pressure were equivalent across the ages. The β2-adrenergic antagonist ICI 118,551 abolished drinking after isoproterenol and prevented most of the observed hypotension. Renin secretion after isoproterenol and salbutamol was greater in young rats than in middle-aged rats, and wholly absent in old rats. Aldosterone secretion was reduced in old rats compared with young and middle-aged rats after treatment with isoproterenol, but not after treatment with salbutamol. In conclusion, there are age-related differences in β-adrenergic receptor-mediated drinking that can be explained only in part by age-related differences in renin secretion after β-adrenergic receptor stimulation.

    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

    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

    Approximately 15% of all ischemic strokes (IS) occur in young adults and adolescents. To date, only limited prior public health and research efforts have specifically addressed stroke in the young. Early diagnosis remains challenging because of the lack of awareness and the relative infrequency of stroke compared with stroke mimics. Moreover, the causes of IS in the young are heterogeneous and can be relatively uncommon, resulting in uncertainties about diagnostic evaluation and cause-specific management. Emerging data have raised public health concerns about the increasing prevalence of traditional vascular risk factors in young individuals, and their potential role in increasing the risk of IS, stroke recurrence, and poststroke mortality. These issues make it important to formulate and enact strategies to increase both awareness and access to resources for young stroke patients, their caregivers and families, and health care professionals. The American Academy of Neurology recently convened an expert panel to develop a consensus document concerning the recognition, evaluation, and management of IS in young adults and adolescents. The report of the consensus panel is presented herein. PMID:23946297

    Shortly after the 1963 passage of the Community Mental Health Centers Act, New York State launched the construction of four new psychiatric centers, including the Richard H. Hutchings Psychiatric Center in Syracuse. The Hutchings acute care crisis stabilization model was intended to significantly diminish the phenomenon of chronic psychiatric disability. After a decade of operation, however, the Hutchings Center must deal with a caseload of young and chronically disabled individuals who are contributing to the build-up both in the hospital and in the community of the new long-stay patient. The idiosyncratic needs of this chronic group must be defined so that prescriptive programs can be built to meet their needs. The Hutchings Center's original goal of returning patients to and serving them in the community remains the same, but the process of treatment, rehabilitation, and long-term community support must change.

    This experiment compared the effects of disuse on the adductor pollicis (AP) muscle in young (YM) and old (OM) men. The AP of the YM and OM was assessed for strength (MVC), compound muscle action potential (CMAP), and volume, and then immobilized for 2 weeks. MVC decreased approximately 22% in the YM, and OM (P<0.001). AP volume was 4.1% (not significant) and 9.5% (P<0.05) less in the YM and OM, respectively. CMAP increased in the OM 0, 24, and 48 h post-immobilization, and did not change in the YM. However, the YM showed a greater decrease in specific force as compared to the OM. YM and OM experienced similar losses in strength, yet muscle volume loss was only significant in OM. Although OM are more susceptible to immediate losses in muscle volume, muscle activation strategies appear to preserve strength during atrophy. PMID:16369818

    Bochdalek hernias (BHs) arise due to congenital diaphragmatic defect and can result in gross displacement of abdominal tissues into the thorax. Although they are uncommon in occurrence, they usually present as serious respiratory distress in infants. In the adult population, they are asymptomatic and only detected incidentally. In this report, we present the case of a 26-year-old male who acutely presented with severe epigastric pain radiating to the back and deranged vital signs as a result of incorrect previous diagnoses. A large left diaphragmatic hernia containing his pancreatic tail, spleen, stomach and other intra-abdominal organs was confirmed by CT scan, together occupying a third of the hemithorax. Although not common, diagnostics of BHs should be considered in patients presenting with acute abdomen. A plain chest X-ray displaying diminished left diaphragmatic outline or signs of mediastinal shift should raise suspicion. Previous normal chest X-ray can be deceptive and does not rule out a diaphragmatic hernia. Herein, we also review the literature for previously reported acute presentation of 11 similar cases in adults and highlight the value of including BH as one of the differential diagnoses.

    2016-03-01

    This article discusses the overweight/obesity situation among young adults in developing countries. For this target population, obesity prevalence ranges from 2.3 to 12 %, and overweight is 28.8 %, mostly affecting females. Weight is now increasing during this life stage of transition at a higher rate, 1 kg/year, than in developed countries. Maternal factors and early childhood socioeconomic status are associated with BMI in young adults along with changing environmental and behavioural factors in some low and middle income countries, brought about by demographic and socioeconomic transitions. Young adults with 'normal weight' obesity need identification using other convenient low cost measures (skin folds or waist circumference) along with BMI. Obesity prevention or management interventions were not identified, but clearly needed to help stem the obesity pandemic. Young people generally give little priority to their future health, so such interventions need to be conducted at some optimal age, be innovative, country specific and culturally acceptable.

    ? Hip dysplasia is a leading precursor of osteoarthritis and is seen in 20% to 40% of patients with osteoarthritis of the hip.? An increase in mechanical stress on the cartilage matrix with failure of the acetabular labrum represents the major pathomechanism of degeneration.? Because the prevalence of associated femoral deformities is high (>50%), the structural anatomy of the dysplastic hip must be assessed in multiple planes using radiographs and, if needed, advanced imaging modalities.? Acetabular osteotomy (periacetabular and/or rotational) is the most commonly used procedure for the treatment of the majority of dysplastic hips in adults.? Modern total hip replacement remains an excellent option for the more arthritic joints. Difficulties can arise from anatomical abnormalities and previous operations. PMID:26738905

    2015-08-30

    This study addresses knowledge gaps regarding family dynamics, and identifies young adults at-risk for psychopathological symptoms. In particular, we examined overparenting and its associations with young adults' adjustment (distress and interpersonal sensitivity). Both direct and indirect relations were assessed, the latter through young adults' relational characteristics (attachment, psychological control perception, and boundaries diffusion perception). Also, the contribution of gender of parents and young adults was addressed. Questionnaires were collected from 89 Jewish-Israeli intact families. Mothers reported significantly more use of overparenting than fathers. More overparenting of fathers had a direct relation with less adjustment in young adults. This direct relation was partially mediated by higher levels of young adults' attachment anxiety (for the dependent variables distress and interpersonal sensitivity) and young adults' perceptions of parental psychological control (for the dependent variable distress). More overparenting of mothers was related to less interpersonal sensitivity for male young adults and for young adults who reported less parental psychological control. This study showed that parenting qualities and their interplay with young adults' relational characteristics continue to play an important role in the lives of young adult offspring. Therefore, clinicians dealing with young adults at risk for, or suffering from, psychopathology, should be attentive to overparenting and its possible implications. PMID:26051175

    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.

    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.

    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

    Two of the most ethically complex situations in pediatrics are those involving families whose religious beliefs preclude the provision of life-sustaining treatment and those involving young adults who have reached the age of legal majority and who face decisions about life-sustaining treatment. This month's "Ethics Rounds" presents a case in which these 2 complexities overlapped. An 18-year-old Jehovah's Witness with sickle cell disease has life-threatening anemia. She is going into heart failure. Her doctors urgently recommend blood transfusions. The young woman and her family adamantly refuse. Should the doctors let her die? Is there any alternative?

    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

    Chronic phase shifts is a common feature in modern societies, which may induce sleep alterations and other health problems. The effects of phase shift on the circadian rhythms have been described to be more pronounced in old than in young animals. However, few works address the effects of chronic phase shifts during adolescence. Here we tested the development of the motor activity circadian rhythm of young rats under chronic phase shifts, which consisted on 6-h advances (A), 6h delays (D) or 6h advances and delays alternated every 5 days (AD) during the first 60 days after weaning. Moreover, the rhythmic pattern was compared to that of adult rats under the same lighting conditions. Results indicate that adolescent rats, independently on the lighting environment, developed a clear circadian rhythm, whose amplitude increased the first 50 days after weaning and showed a more stable circadian rhythm than adults under the same lighting conditions. In the case of A and AD groups, circadian disruption was observed only in adult rats. In all groups, the offset of activity correlated with light pattern better than the onset, and this correlation was always higher in the case of the rhythm of the pubertal rats. When AD groups were transferred to constant darkness, the group submitted to this condition during adolescence showed shorter period than that submitted in their adulthood. In conclusion, differently from adult rats, adolescent rats submitted to chronic phase shifts did not show circadian disruption and developed a single circadian rhythm, suggesting permanent changes in the circadian system.

    Iron is an essential element. However, in its free form, iron participates in redox-reactions, leading to the production of free radicals that increase oxidative stress and the risk of damaging processes. Living organisms have an efficient mechanism that regulates iron absorption according to their iron content to protect against oxidative damage. The effects of restricted and enriched-iron diets on oxidative stress and aging biomarkers were investigated. Adult Wistar rats were fed diets containing 10, 35 or 350 mg/kg iron (adult restricted-iron, adult control-iron and adult enriched-iron groups, respectively) for 78 days. Rats aged two months were included as a young control group. Young control group showed higher hemoglobin and hematocrit values, lower levels of iron and lower levels of MDA or carbonyl in the major studied tissues than the adult control group. Restricted-iron diet reduced iron concentrations in skeletal muscle and oxidative damage in the majority of tissues and also increased weight loss. Enriched-iron diet increased hematocrit values, serum iron, gamma-glutamyl transferase, iron concentrations and oxidative stress in the majority of tissues. As expected, young rats showed higher mRNA levels of heart and hepatic L-Ferritin (Ftl) and kidneys SMP30 as well as lower mRNA levels of hepatic Hamp and interleukin-1 beta (Il1b) and also lower levels of liver protein ferritin. Restricted-iron adult rats showed an increase in heart Ftl mRNA and the enriched-iron adult rats showed an increase in liver nuclear factor erythroid derived 2 like 2 (Nfe2l2) and Il1b mRNAs and in gut divalent metal transporter-1 mRNA (Slc11a2) relative to the control adult group. These results suggest that iron supplementation in adult rats may accelerate aging process by increasing oxidative stress while iron restriction may retards it. However, iron restriction may also impair other physiological processes that are not associated with aging. PMID:23593390

    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

    Objective To describe the development and psychometric properties of survey measures relevant to eating, physical activity, and weight-related behaviors among young adults. Methods Focus groups and reliability testing guided the development of the Project EAT-III survey. The final survey was completed by 2,287 young adults. Results The systematic process employed led to a psychometrically sound and developmentally appropriate survey. Test-retest reliabilities for items included on the final survey were mostly moderate to good and Cronbachs alphas were >0.7 for 83% of developed scales. Conclusions Future studies may find the systematic process used to be helpful in creating other weight-related surveys. PMID:22251762

    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

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.

    The aim of the study was to examine reinforcement learning (RL) in young adults with developmental language impairment (DLI) within the context of a neurocomputational model of the basal ganglia-dopamine system (Frank et al., 2004). Two groups of young adults, one with DLI and the other without, were recruited. A probabilistic selection task was used to assess how participants implicitly extracted reinforcement history from the environment based on probabilistic positive/negative feedback. The findings showed impaired RL in individuals with DLI, indicating an altered gating function of the striatum in testing. However, they exploited similar learning strategies as comparison participants at the beginning of training, reflecting relatively intact functions of the prefrontal cortex to rapidly update reinforcement information. Within the context of Franks model, these results can be interpreted as evidence for alterations in the basal ganglia of individuals with DLI. PMID:22921956

    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

    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.

    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.

    Abstract The relationship between atopic dermatitis (AD) and psychological distress has been well established for children and adolescents. However, it is unclear whether this relationship exists in young adults. This study aimed to assess the relationship between AD and psychological distress in young male adults in South Korea. A cross-sectional study was conducted using regional conscription data from 2008 to 2012. A dermatologist diagnosed AD based on historical and clinical features, and determined severity using the eczema area and severity index. A psychiatrist used medical records, an interview, and a psychological test to examine psychological distress (depression, anxiety, and somatization). The relationship between psychological distress and AD was assessed by multivariate logistic regression analyses. Among the 120,508 conscripts, 1517 (1.2%) presented with AD. The odds of having each type of psychological distress were significantly greater for individuals with AD compared with those without AD. The adjusted odds ratios for depression, anxiety, and somatization were 1.79 (95% CI 1.402.29), 1.38 (95% CI 1.081.76), and 1.75 (95% CI 1.402.20), respectively. Moderate-to-severe AD was significantly related to depression and somatization to a greater extent compared with mild AD. Depression, anxiety, and somatization are strongly and independently associated with AD in young adult males. Early treatment of skin inflammation might modify the risk of psychiatric problems. Prospective cohort studies are needed to verify causal relationships. PMID:26061325

    Background Emerging research suggests that young adult sexual minorities (identifying as lesbian, gay, or bisexual or engaging in same-sex attractions or behaviors) experience poorer health than their majority counterparts, but many measures of health inequity remain unexamined in population-based research. Purpose To describe a wide range of health status and healthcare access characteristics of sexual minorities in comparison with those of the majority population in a national sample of U.S. young adults. Methods Binary and multinomial logistic regression analyses of Wave IV data (2008) from the National Longitudinal Study of Adolescent Health (participants aged 24–32 years, n=13,088) were conducted. Health measures were self-rated health; diagnosis of any of several physical or mental illnesses or sexually transmitted infections; measured body mass index; depression classified from self-reported symptoms; use of antidepressant and anxiolytic medication; uninsured; forgone care; and receipt of physical, dental, and psychological services. Analyses were conducted in 2012–2013. Results Sexual minority women had elevated odds of most adverse health conditions and lower odds of receiving a physical or dental examination. Sexual minority men had elevated odds of fewer adverse health conditions. Conclusions Young adult sexual minorities are at higher risk of poor physical and mental health. The results highlight the multidimensionality of sexual minority status and respond to calls for greater understanding of the health of this population. PMID:25241194

    Extensive research over the past 30 years has revealed that individual and social determinants impact HIV risk. Even so, prevention efforts focus primarily on individual behaviour change, with little recognition of the dynamic interplay of individual and social environment factors that further exacerbate risk engagement. Drawing on long-term research with young adults in Lesotho, I examine how social environment factors contribute to HIV risk. During preliminary ethnographic analysis, I developed novel scales to measure social control, adoption of modernity, and HIV knowledge. In survey research, I examined the effects of individual characteristics (i.e., socioeconomic status, HIV knowledge, adoption of modernity) and social environment (i.e., social control) on HIV risk behaviours. In addition, I measured the impact of altered environments by taking advantage of an existing situation whereby young adults attending a national college are assigned to either a main campus in a metropolitan setting or a satellite campus in a remote setting, irrespective of the environment in which they were socialised as youth. This arbitrary assignment process generates four distinct groups of young adults with altered or constant environments. Regression models show that lower levels of perceived social control and greater adoption of modernity are associated with HIV risk, controlling for other factors. The impact of social control and modernity varies with environment dynamics. PMID:26284999

    Objectives. We evaluated a Social Branding antitobacco intervention for “hipster” young adults that was implemented between 2008 and 2011 in San Diego, California. Methods. We conducted repeated cross-sectional surveys of random samples of young adults going to bars at baseline and over a 3-year follow-up. We used multinomial logistic regression to evaluate changes in daily smoking, nondaily smoking, and binge drinking, controlling for demographic characteristics, alcohol use, advertising receptivity, trend sensitivity, and tobacco-related attitudes. Results. During the intervention, current (past 30 day) smoking decreased from 57% (baseline) to 48% (at follow-up 3; P = .002), and daily smoking decreased from 22% to 15% (P < .001). There were significant interactions between hipster affiliation and alcohol use on smoking. Among hipster binge drinkers, the odds of daily smoking (odds ratio [OR] = 0.44; 95% confidence interval [CI] = 0.30, 0.63) and nondaily smoking (OR = 0.57; 95% CI = 0.42, 0.77) decreased significantly at follow-up 3. Binge drinking also decreased significantly at follow-up 3 (OR = 0.64; 95% CI = 0.53, 0.78). Conclusions. Social Branding campaigns are a promising strategy to decrease smoking in young adult bar patrons. PMID:24524502

    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

    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

    Under physiological conditions, lymphatic vessels are thought to be absent from the central nervous system (CNS), although they are widely distributed within the rest of the body. Recent work in the eye, i.e., another organ regarded as alymphatic, revealed numerous cells expressing lymphatic markers. As the latter can be involved in the response to pathological conditions, we addressed the presence of cells expressing lymphatic markers within the spinal cord by immunohistochemistry. Spinal cord of young adult Fisher rats was scrutinized for the co-expression of the lymphatic markers PROX1 and LYVE-1 with the cell type markers Iba1, CD68, PGP9.5, OLIG2. Rat skin served as positive control for the lymphatic markers. PROX1-immunoreactivity was detected in many nuclei throughout the spinal cord white and gray matter. These nuclei showed no association with LYVE-1. Expression of LYVE-1 could only be detected in cells at the spinal cord surface and in cells closely associated with blood vessels. These cells were found to co-express Iba1, a macrophage and microglia marker. Further, double labeling experiments using CD68, another marker found in microglia and macrophages, also displayed co-localization in the Iba1+ cells located at the spinal cord surface and those apposed to blood vessels. On the other hand, PROX1-expressing cells found in the parenchyma were lacking Iba1 or PGP9.5, but a significant fraction of those cells showed co-expression of the oligodendrocyte lineage marker OLIG2. Intriguingly, following spinal cord injury, LYVE-1-expressing cells assembled and reorganized into putative pre-vessel structures. As expected, the rat skin used as positive controls revealed classical lymphatic vessels, displaying PROX1+ nuclei surrounded by LYVE-1-immunoreactivity. Classical lymphatics were not detected in adult rat spinal cord. Nevertheless, numerous cells expressing either LYVE-1 or PROX1 were identified. Based on their localization and overlapping expression with Iba1, the LYVE-1+ cell population likely represents a macrophage subpopulation, while a significant fraction of PROX1+ cells belong to the oligodendrocytic lineage based on their distribution and the expression of OLIG2. The response of these LYVE-1+ and PROX1+ cell subpopulations to pathological conditions, especially in spinal cord inflammatory conditions, needs to be further elucidated. PMID:26903808

Intriguingly, following spinal cord injury, LYVE-1-expressing cells assembled and reorganized into putative pre-vessel structures. As expected, the rat skin used as positive controls revealed classical lymphatic vessels, displaying PROX1+ nuclei surrounded by LYVE-1-immunoreactivity. Classical lymphatics were not detected in adult rat spinal cord. Nevertheless, numerous cells expressing either LYVE-1 or PROX1 were identified. Based on their localization and overlapping expression with Iba1, the LYVE-1+ cell population likely represents a macrophage subpopulation, while a significant fraction of PROX1+ cells belong to the oligodendrocytic lineage based on their distribution and the expression of OLIG2. The response of these LYVE-1+ and PROX1+ cell subpopulations to pathological conditions, especially in spinal cord inflammatory conditions, needs to be further elucidated. PMID:26903808

    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.

    Social norms-based interventions have shown promise in reducing drinking behavior and resulting consequences in young adults. Although most research has focused on young civilians (i.e., college students), some studies have investigated social norms-based interventions with active duty military and veteran samples. Yet, research has not yet determined how to maximize the effectiveness of social norms-based intervention in this heavy drinking population. As an initial step toward this goal, the current study utilized a community sample of 1,023 young adult veterans to examine: (1) whether veteran perceptions of the drinking behavior of their veteran peers differ from their perceptions of civilian drinking behavior, (2) whether perceptions of specific veteran groups differ from actual drinking behavior of veterans within those groups, (3) what levels of specificity in reference groups (same-gender civilians, same-branch veterans, same-gender veterans, or same-branch-and-same-gender veterans) are most strongly associated with veterans’ own drinking, and (4) whether perceptions about others’ attitudes toward drinking also contribute independently of perceived behavioral norms to veteran drinking. Findings indicated that participants perceived that other veterans drank more than civilians and that veteran groups drank more than veterans in the sample actually drank. Veteran-specific perceived behavioral norms were similar in their associations with drinking outcomes, whereas same-gender civilian perceived behavioral norms exhibited little or no associations with drinking. Veteran-specific perceived attitudinal norms exhibited little or no association on drinking behavior after controlling for perceived behavioral norms. These findings can be used to inform the development of social norms interventions for young adult veterans. PMID:26415056

    Hippocampal function varies in a subregion-specific fashion: spatial processing is thought to rely on the dorsal hippocampus, whereas anxiety-related behavior relies more on the ventral hippocampus. During development, neurogenesis in the dentate gyrus (DG) 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 DG 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 DG. 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 DG. 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 DG subregions and with different experiential specificity, and suggest that adult-born neurons may play a specific role in anxiety-related behavior or other nonspatial aspects of hippocampal function.

    This study describes young adult female college students' perceptions of risky social media behaviors. A sample of 14 young adult females, aged 18-22 years and residing in an urban university, participated in 1 of 3 focus groups held in campus housing. Data analysis yielded 4 themes surrounding young adults' engagement in risky behaviors associated with social media. Themes described the predominant culture, associated risk, and prevention. Important insights into young adult female college students' thoughts on risky social media behaviors can be used by advanced practice nurses to inform preventive education for young college women.

    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

    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 / 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.

    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

    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

    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 (Aub 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

    2012-01-01

    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

    2008-05-01

    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

    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.

    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 (Smer, 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 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.

    We examined verbal sexual health communication, pleasure discussions, and physical sexual communication in relation to condom use by young adult, heterosexual Latinos (ages 18-30years). Participants (N=220, 51% female) were recruited in a Midwestern state. Verbal sexual health communication was positively associated with consistent condom use among men (odds ratio [OR]=2.66, p<.05) and women (OR=3.12, p<.05). For men, pleasure discussions were negatively associated with consistent condom use (OR=0.21, p<.05). For women, verbal sexual health communication was positively associated with condom use at last sex (OR=2.75, p<.05), whereas physical sexual communication was negatively associated with condom use at last sex (OR=.29, p<.05). Various aspects of sexual communication may be important in HIV-prevention programs with young Latinos. Physical sexual communication and pleasure discussions, in particular, warrant further exploration given negative relationships with condom use. PMID:25305027

    (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.

    Objectives The study aimed to assess whether young binge drinkers have impaired macrovascular and microvascular function and cardiovascular (CV) disease risk factors compared to age-matched alcohol abstainers. Background Binge drinking rates are highest on college campuses and among 18- to 25-year-olds; however, macrovascular and microvascular endothelial function in young adults with a history of repeated binge drinking (?5 standard drinks in 2 hrs. in men; ?4 standard drinks in 2 hrs. in women) has not been investigated Methods We evaluated the cardiovascular profile, brachial artery endothelial-dependent flow mediated vasodilation (FMD), and flow independent nitroglycerin (NTG)-mediated dilation and vasoreactivity of resistance arteries (isolated from gluteal fat biopsies) in abstainers and binge drinkers. Results Men and women (1825 years of age, abstainers [A] n = 17, binge drinkers [BD] n = 19) were enrolled. Among the BD group, past-month average number of binge episodes was 6 1, and average duration of binge drinking behavior was 4 0.6 years. FMD and NTG-mediated dilations were significantly lower in the BD (FMD: 8.4% 0.7, P = 0.022; NTG: 19.6% 2, P = 0.009) than the A group (FMD: 11 0.7%; NTG: 28.6 2%). ACh- and SNP-induced dilation in resistance arteries was not significantly different between the A and BD groups. However, ET-1-induced constriction was significantly enhanced in the BD group compared to the A group (P = 0.032). No differences between groups were found in blood pressure, lipoproteins, and C-reactive protein. Conclusions Alterations in the macrocirculation and microcirculation may represent early clinical manifestations of CV risk in otherwise healthy young binge drinkers. This study has important clinical implications for screening young adults for a repeated history of binge drinking. PMID:23623907

    Aims Youth cultures play a key role in the social organisation of drug trends among young people; the current prescription drug misuse trend is no different. The authors evaluated whether patterns of prescription drug misuse differed across several youth cultures. Methods Using field survey methods and time-space sampling during 2011, the authors assessed the patterns and prevalence of prescription drug misuse among young adults who are socially active in various urban youth cultures (n = 1781). Findings The prevalence of lifetime prescription drug misuse is highest within indie rock scenes (52.5%), electronic dance music scenes (52.1%), lesbian parties (53.8%) and alt scenes (50.9%). Prescription drug misuse was lowest among young adults in hip-hop scenes (25.0%). These findings were upheld in logistic regression analyses that accounted for demographic differences across youth cultures: indie rock scenes (adjusted odds ratio = 2.11), electronic dance music scenes (adjusted odds ratio = 2.20), lesbian parties (adjusted odds ratio = 2.30) and alt scenes (adjusted odds ratio = 2.65) all reported statistically significant (P < 0.05) higher odds of misuse than college bar scenes. Recent prescription drug misuse mirrored patterns for lifetime misuse. Conclusions: The differing prevalence of prescription drug misuse across distinct youth cultures suggests that the trend has not diffused equally among young people. The differing prevalence across youth cultures indicates that the most efficacious strategies for youth intervention may be targeted approaches that account for the subculturally rooted differences in attitudes and social norms.

    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 1729 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 Despite many activities to prevent risky alcohol consumption among adolescents and young adults there is an increase of alcohol intoxications in the group of ten to twenty year old juveniles. Objectives This report gives an overview about the recent literature as well as the German federal prevention system regarding activities concerning behavioral and policy prevention of risky alcohol consumption among children, adolescents and young adults. Furthermore, effective components of prevention activities are identified and the efficiency and efficacy of ongoing prevention programs is evaluated. Methods A systematic literature review is done in 34 databases using Boolsche combinations of the key words alcohol, prevention, treatment, children, adolescents and young adults. Results 401 studies were found and 59 studies were selected for the health technology assessment (HTA). Most of the studies are done in USA, nine in Germany. A family strengthening program, personalized computer based intervention at schools, colleges and universities, brief motivational interventions and policy elements like increase of prices and taxes proved effective. Discussion Among the 59 studies there are three meta-analyses, 15 reviews, 17 randomized controlled trials (RCT) and 18 cohort studies. Despite the overall high quality of the study design, many of them have methodological weaknesses (missing randomization, missing or too short follow-ups, not clearly defined measurement parameters). The transferability of US-results to the German context is problematic. Only a few prevention activities reach a sustainable reduction of frequency and/or amount of alcohol consumption. Conclusion The HTA-report shows the need to develop specific and target group focused prevention activities for the German situation. Essential for that is the definition of target goals (reduction of consumption, change of behaviour) as well as the definition and empirical validation of risky alcohol consumption. The efficacy of prevention activities should be proven before they are launched. At present activities for the reduction or prevention of risky alcohol consumption are not sufficiently evaluated in Germany concerning their sustainable efficacy. PMID:21808659

    A variety of age-related differences in the innate and adaptive immune systems have been proposed to contribute to the increased susceptibility to infection of human neonates and older adults. The emergence of RNA sequencing (RNA-seq) provides an opportunity to obtain an unbiased, comprehensive, and quantitative view of gene expression differences in defined cell types from different age groups. An examination of ex vivo human monocyte responses to lipopolysaccharide stimulation or Listeria monocytogenes infection by RNA-seq revealed extensive similarities between neonates, young adults, and older adults, with an unexpectedly small number of genes exhibiting statistically significant age-dependent differences. By examining the differentially induced genes in the context of transcription factor binding motifs and RNA-seq data sets from mutant mouse strains, a previously described deficiency in interferon response factor-3 activity could be implicated in most of the differences between newborns and young adults. Contrary to these observations, older adults exhibited elevated expression of inflammatory genes at baseline, yet the responses following stimulation correlated more closely with those observed in younger adults. Notably, major differences in the expression of constitutively expressed genes were not observed, suggesting that the age-related differences are driven by environmental influences rather than cell-autonomous differences in monocyte development.

    The family practitioner, pediatrician, and dermatologist each have potential roles in the primary prevention, diagnosis, and treatment of localized thin melanomas. Surgical and medical oncologists are often involved when controversy arises over the nature of the skin lesion or whether sentinel lymph node (SLN) biopsies and adjuvant therapy are to be contemplated. This overview of melanoma will deal with the primary and nodal pathology, surgery, and medical therapy of melanoma in pediatric, adolescent, and young adult patientsand will raise areas of controversy that are only recently being addressed in databases of cases from this age group.

    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.

    The recent increase in the number of girls involved in the juvenile justice system has resulted in increased academic and public attention. Thus far, this attention has focused on entry into the juvenile justice system rather than longer-term consequences. This research helps fill this gap by examining a sample of 700 maltreated and/or impoverished juvenile courtinvolved females. Competing risks models were used to control for time from juvenile-court entry to adult outcomes: criminal justice system involvement, use of public mental health or substance use services, and income maintenance use. Results indicate that there are distinct predictors associated with the different outcomes, although learning disability and adolescent parenthood were associated with higher risk of both mental health/substance use services and income maintenance. Individualized services for juvenile courtinvolved girls are suggested. Prospective, longitudinal research is needed to investigate intrapsychic and behavioral dynamics associated with females young adult outcomes. PMID:23430819

    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.

    Purpose: Colorectal cancer (CRC) incidence has decreased over the past three decades, due largely to screening efforts. Relatively little is known about CRC incidence among the young adult (YA) population ages 2039, as screening typically commences at age 50 for average-risk individuals. We examined CRC incidence with a focus on YAs in order to identify high-risk subgroups. Methods: We analyzed 231,544 incident CRC cases from 19882009 (including 5617 YAs 2039 years of age) from the California Cancer Registry. We assessed age-specific incidence rates by race/ethnicity, gender, and colorectal tumor location, and calculated the biannual percent change (BAPC) to monitor change in incidence over the 22-year study period. Results: The absolute incidence of CRC per 100,000 was low among YAs 2029 and 3039 years old (ranging from 0.7 per 100,000 among Hispanic and African American females aged 2029 up to 5.0 per 100,000 among Asian/Pacific Islander males aged 3039). However, we observed increasing CRC incidence rates over time among both males and females in the YA population, particularly for distal colon cancer in Hispanic females aged 2029 (BAPC=+15.9%; p<0.042). Conclusion: The absolute incidence of CRC remains far lower for YAs than among adults aged 50 and over. However, CRC incidence is increasing among young adults, in contrast to the decreasing rates observed for adults in the screened population (aged 50 and above). More research is needed to better characterize YAs at increased risk for CRC. PMID:25538862

    Clones were derived by dilute plating from cultured aortic smooth muscle cells of 12-day-old rats. Clones Pup I to III resemble uncloned smooth muscle cultures from aortas of rat pups and from adult rat neointimas. They have a cobblestone morphology and proliferate in plasma-derived serum. By Northern analysis they contain platelet-derived growth factor B chain (PDGF-B) mRNA and high levels of CYPIA1, elastin, and osteopontin mRNAs, and they lack platelet-derived growth factor alpha-receptor (PDGF-alpha R) mRNA. In contrast, Pup V resembles smooth muscle cultures derived from uninjured adult rat arteries. It has an elongated morphology and proliferates poorly in plasma-derived serum. This clone expresses PDGF-alpha R mRNA, low levels of elastin and osteopontin mRNAs, and lacks CYPIA1 and PDGF-B mRNAs. Pup IV and VI have most of the properties of Pup I to III. We conclude that uncloned pup cultures are heterogeneous, but that the growth properties and gene expression pattern described for the uncloned culture is characteristic of individual clones within the population.

    Introduction Cigarette smoking is an addictive behaviour which continues to rise among young adults. It has been associated with various health hazards. Effect of smoking on cognitive function has been contradicting. Thus our aim was to compare cognitive performances between smokers and non smokers and also to observe the effect of varying intensity of smoking on cognition. Materials and Methods This is a cross-sectional study. Thirty non smokers, 30 mild smokers, 30 moderate smokers, 30 heavy smokers within the age group of 25-35 years were involved in the study. Their cognitive performance were assessed by digit symbol substitution test (DSST), digit vigilance test (DVT), visual reaction time (VRT), letter cancellation test (LCT), word recall (WR), and object recall (OR). Result The cognitive data were analysed using unpaired students t-test and ANOVA in SPSS 19. Smokers showed significant decline in their cognitive performances when compared to smokers (p ? 0.05). Mild smokers showed significantly better performance in the DSST, DVT and VRT tests than the non smokers. This indicates the attention and alertness were better in mild smokers than the non smokers. With the increase in the intensity of smoking cognitive performances were also significantly declined. Conclusion Thus the study indicates decreased cognitive performances in young adult smokers.

    Accumulating data suggest that depression is associated with risk factors for cardiovascular disease, but few studies have investigated potential behavioral mediators of such associations, particularly among women. In this study of healthy young adult women (n=225), we examined associations among depressive symptoms, health behaviors, and serum lipid levels. Depressive symptoms were assessed with the 20-item Center for Epidemiologic Studies-Depression scale, and a fasting blood sample was obtained for serum lipid levels, including total cholesterol, high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C). Diet was measured using 24-h recalls, and other health behaviors (physical activity, smoking) were assessed via self-report questionnaire. Results indicated a modest negative association between depressive symptoms and LDL-C levels. Higher levels of depressive symptoms were also associated with lower total and insoluble dietary fiber intake, both of which were associated with HDL-C and LDL-C. Mediational analyses indicated a significant indirect effect of depressive symptoms on LDL-C via total and insoluble dietary fiber in unadjusted analyses, but not in adjusted analyses. The present findings suggest that depressive symptoms are inversely associated with serum LDL-C levels in young adult women, but that these associations are not likely mediated by adverse lifestyle behaviors.

    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

    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

    We investigate determinants of subjective social status (SSS) as measured by respondents placing themselves on a ten-rung ladder from least to most "money", "education" and "respected job", in a large sample of young adults. The most potent clues of SSS are proximate in the life course, reflecting educational attainment and current socioeconomic and job situation, rather than distal characteristics such as family background, although relatively distal High school GPA has a lingering effect. Additional analyses reveal that College selectivity has a substantial impact on SSS, net of other variables in the model; Currently married does not significantly contribute to SSS, but contrary to some expectations Number of children significantly lowers SSS. We find no evidence of greater "status borrowing" by women as associations of SSS with shared household characteristics (Household income, Household assets, Home ownership) do not differ by gender. Our findings for these young adults support the conclusion of earlier research that SSS reflects a "cognitive averaging" of standard dimensions of socioeconomic status. PMID:26004468

    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.

    Previous research confirms a strong empirical association between the racial composition of young adults' residential areas and the racial compositions of the residential areas and schools of their youth. Perpetuation theory predicts that part of this association is causal. The present study uses data from the National Education Longitudinal Study (NELS) and the U.S. Censuses of 1990 and 2000 to test for this effect with regression models, propensity-score-weighted models with robustness tests, and regression models that look at long-distance movers. The findings suggest that the association declines rapidly as the distance moved increases, but it remains robust even at long distances. It is also stronger for African Americans and more assimilated Latinos than for whites and less assimilated Latinos. These findings suggests that to some extent, young white, African American, and Latino adults are residentially segregated from each other because they grew up that way. Policies that promote integrating youth residentially and/or desegregating schools may contribute to residential integration over time. PMID:26857168

    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 (2236 years) and elderly (6695 years) adults engaged in a visual task. The MMR was found to deviants as compared to standards at two latency ranges: 180220 ms and 250290 ms post-stimulus onset. At 180220 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 250290 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.

    Trends in mortality from all neoplasms and major cancer sites in Switzerland among populations aged between 20 and 44 years are presented. In men total cancer mortality was approximately constant around 270/10(6) between 1951 and 1965, but declined appreciably thereafter to 217 per million in 1980-1989. The overall fall was 20%. The pattern of trends was similar for women, although a modest decline was already apparent in the earlier calendar period, and the overall fall was 29% (from 303 to 215/10(6)). These favourable trends reflect therapeutic advancements for Hodgkin's disease, leukaemias, testis and (chiefly non-epithelial) ovarian cancer, better control of cervical cancer, the long-term decline in gastric cancer, but also the downward trends in cancer of the intestines and a few less common sites, such as gallbladder and thyroid neoplasms for reasons that are not yet clear. Appreciable rises were observed for lung and other tobacco-related sites in women, for the oral cavity in men and (in earlier calendar periods) cutaneous melanoma in both sexes. Although restricted to a selected number of sites, these rises are discouraging, since the causes of these neoplasms have long been recognized. Somewhat discouraging also is the absence of decline in male lung cancer. These problems notwithstanding, the overall pattern of trends in cancer mortality in young Swiss adults over the last few decades is still reassuring, particularly in comparison with those observed in other European countries, and in the more general framework of the debate on the perspectives of progress in cancer control. Although restricted to a small proportion of all cancer deaths, in fact, trends in young adults offer useful indications on the likely future trends in the same generations in the near future, since they reflect more recent changes in the pattern of exposure. The size of the changes, however, will probably differ, since the prevalent cancers in middle age are different from those in the young. PMID:1890144

    Objective: Given the evidence that several cognitive and emotional functions are impaired in adult alcohol-dependent patients and the possibility that some of these deficits are transmitted to their children, the objective of the present study was to test the hypothesis that the perception of complex mental states would be reduced in young adults from families with a positive family history of alcohol dependence. It was also anticipated that social-perceptual deficits would confer unique predictive ability beyond that shared with other cognitive risk factors for alcohol dependence and/or substance use risk. Method: Data from 301 youth ages 1821 years, recruited from an ongoing community longitudinal study of alcoholic and matched control families, were analyzed. Family history of alcohol dependence as well as alcohol-dependence diagnosis in the youth was based on diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. A substance use risk factor measured early problem alcohol/other drug use. The perception of mental states was measured with the computerized version of the Reading the Mind in the Eyes Test (RMET). Results: Children of alcohol-dependent parents did not show impairment in the mental states perception task, nor did social perception skills predict alcohol dependence in the youth. Correlational analysis performed between RMET and the substance use risk factor showed no significant association between the variables. Conclusions: The study results do not confirm the hypothesis that behaviorally measured social perception impairment is more prevalent in the children of alcohol-dependent parents. In addition, social-perceptual deficits were not a unique marker of either alcohol dependence or high risk for alcohol dependence in this young adult sample. PMID:25208207

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

    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

    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.

    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.

    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.

    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 1834 (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.

    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.

    The acoustic characteristics of sustained vowel have been widely investigated across various languages and ethnic groups. These acoustic measures, including fundamental frequency (F(0)), jitter (Jitt), relative average perturbation (RAP), five-point period perturbation quotient (PPQ5), shimmer (Shim), and 11-point amplitude perturbation quotient (APQ11) are not well established for Malaysian Malay young adults. This article studies the acoustic measures of Malaysian Malay adults using acoustical analysis. The study analyzed six sustained Malay vowels of 60 normal native Malaysian Malay adults with a mean of 21.19 years. The F(0) values of Malaysian Malay males and females were reported as 134.8518.54 and 238.2724.06Hz, respectively. Malaysian Malay females had significantly higher F(0) than that of males for all the vowels. However, no significant differences were observed between the genders for the perturbation measures in all the vowels, except RAP in /e/. No significant F(0) differences between the vowels were observed. Significant differences between the vowels were reported for all perturbation measures in Malaysian Malay males. As for Malaysian Malay females, significant differences between the vowels were reported for Shim and APQ11. Multiethnic comparisons indicate that F(0) varies between Malaysian Malay and other ethnic groups. However, the perturbation measures cannot be directly compared, where the measures vary significantly across different speech analysis softwares. PMID:21429707

    Despite the rapid growth of the gambling industry over the last 40 years, there have been few large-scale, nationally representative longitudinal studies of gambling among young adults. We use data from the National Longitudinal Study of Adolescent to Adult Health to investigate whether and how the gambling behavior of young adults is associated with their religious beliefs and practices during adolescence. We find that young adults who grew up as conservative Protestants, mainline Protestants, Mormons, and Jehovah's Witnesses; those were raised in a community with a higher percentage of conservative Protestants; and those who attended religious services weekly are less likely to have ever gambled. Among gamblers, young adults who attended religious services up to three times per month as adolescents are more likely to experience gambling problems than those who never attend. Notably, accounting for a young adult's propensity for risk-taking behavior does not explain the associations between religion and gambling. PMID:25722077

    2014-01-01

    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.

    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

    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

    This study examined whether or not the acoustic startle response and sensorimotor gating may be modulated by emotions differentially between young and older adults. Two groups of participants (mean age Young: 24 years old; Elderly: 63.6 years old) were presented with three types of auditory stimuli (Startle alone, High or Low frequency Prepulse) while viewing pleasant, neutral, or unpleasant images. Electromyographic activity of the eyeblink response was measured. Results show that older adults displayed diminished eyeblink responses whereas younger adults displayed enhanced eyeblink responses when viewing negative images. Sensorimotor gating also differed between young and older adults, with enhanced sensorimotor gating abilities while viewing positive pictures in older adults and diminished abilities while viewing negative pictures among younger adults. These results argue in favor of a differential emotional influence on the sensorimotor abilities of young and older adults, with a positivity bias among the latter. PMID:26941643

    2015-01-01

    Adults are more accurate in detecting deviations from normality in young adult faces than in older adult faces despite exhibiting comparable accuracy in discriminating both face ages. This deficit in judging the normality of older faces may be due to reliance on a face space optimized for the dimensions of young adult faces, perhaps because of early and continuous experience with young adult faces. Here we examined the emergence of this young adult face bias by testing 3- and 7-year-old children on a child-friendly version of the task used to test adults. In an attractiveness judgment task, children viewed young and older adult face pairs; each pair consisted of an unaltered face and a distorted face of the same identity. Children pointed to the prettiest face, which served as a measure of their sensitivity to the dimensions on which faces vary relative to a norm. To examine whether biases in the attractiveness task were specific to deficits in referencing a norm or extended to impaired discrimination, we tested children on a simultaneous match-to-sample task with the same stimuli. Both age groups were more accurate in judging the attractiveness of young faces relative to older faces; however, unlike adults, the young adult face bias extended to the match-to-sample task. These results suggest that by 3 years of age, children's perceptual system is more finely tuned for young adult faces than for older adult faces, which may support past findings of superior recognition for young adult faces.

    Background The purpose of this study is to provide Dutch norm data and to assess internal consistency and construct validity for the Pediatric Quality of Life Inventory Young Adult Generic Core Scales (PedsQL_YA) in Dutch young adults aged 1830years. Methods A sample of 649 young adults from the general Dutch population aged 1830years, stratified by age, sex, marital status and education, completed a socio-demographic questionnaire and the Dutch version of the PedsQL_YA online. Internal consistency of the PedsQL_YA scales was determined with Cronbachs alphas. Norm scores were obtained by calculating the mean PedsQL scale scores by gender, age and health status. Differences in scale scores were analyzed for gender, age and health status (construct validity) using two-sample t-tests and effect sizes were calculated. Construct validity was determined by testing differences in PedsQL scores between healthy young adults and young adults with chronic health conditions. Results All scales of the PedsQL_YA showed satisfactory to excellent internal consistency, with Cronbachs alphas between .77 and .94.

    Low doses (10 or 350 ME) of human interferon-alpha (HIA) were intranasally applied to young (3-4 months) and ageing (12-15 months) Wistar rats during food conditioning. In control groups, development of the conditioned reflex to acoustic stimulus (tone) did not differ significantly in young and ageing rats in the course of chronic applications of the HIA. However, the control ageing rats were better than young rats in time-interval conditioning. Small doses of HIA do not cause anorexia in rats whereas large doses do so. Tone-conditioning did not change in rats of both ages when they were treated with 10 ME of the HIA; moreover, 350 ME increased food motivation, especially in young rats. Time-interval conditioning in aging rats was descended by both doses to the level of young rats, whereas in young rats it did not change at all. We suggest that these differences between ages may by accounted for be different affinity and concentration of micro-opiod receptors (which are the targets for the HIA) in the brain structures responsible for food behaviour, and for counting time intervals.

  16. Aging faces and aging perceivers: young and older adults are less sensitive to deviations from normality in older than in young adult faces.

    Past studies examining the other-age effect, the phenomenon in which own-age faces are recognized more accurately than other-age faces, are limited in number and report inconsistent results. Here we examine whether the perceptual system is preferentially tuned to differences among young adult faces. In experiment 1 young (18-25 years) and older adult (63-87 years) participants were shown young and older face pairs in which one member of each pair was undistorted and the other had compressed or expanded features. Participants indicated which member of each pair was more normal and which was more expanded. Both age groups were more accurate when tested with young compared with older faces-but only when judging normality. In experiment 2 we tested a separate group of young adults on the same two tasks but with upright and inverted face pairs to examine the differential pattern of results between the normality and discrimination tasks. Inversion impaired performance on the normality task but not the discrimination task and eliminated the young adult advantage in the normality task. Collectively, these results suggest that the face processing system is optimized for young adult faces and that abundant experience with older faces later in life does not reverse this perceptual tuning.

    Adolescence and young adulthood are unique developmental periods that present opportunities and challenges for improving health. Health at this age can affect health throughout the lifespan. This review has two aims: (1) to examine trends in key indicators in outcomes, behaviors, and health care over the past decade for U.S. adolescents and young adults; and (2) to compare U.S. adolescents and young adults on these indicators. The review also assesses sociodemographic differences in trends and current indicators. Guided by our aims, previous reviews, and national priorities, the present review identified 21 sources of nationally representative data to examine trends in 53 areas and comparisons of adolescents and young adults in 42 areas. Most health and health care indicators have changed little over the past decade. Encouraging exceptions were found for adolescents and young adults in unintentional injury, assault, and tobacco use, and, for adolescents, in sexual/reproductive health. Trends in violence and chronic disease and related behaviors were mixed. Review of current indicators demonstrates that young adulthood continues to entail greater risk and worse outcomes than adolescence. Young adults fared worse on about two-thirds of the indicators examined. Differences among sociodemographic subgroups persisted for both trends and current indicators. PMID:24815958

    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.

    When two or more people witness an event together, the event report from one person can influence others' reports. In the current study we examined the role of age and motivational factors on peer influence regarding event reports in adolescents and young adults. Participants (N=249) watched a short video of a robbery then answered questions with no co-witness information or with information believed to be from a co-witness. Public and private response conditions were included to explore motivations for peer influence. Co-witness information influenced participants' responses, although the effect was equally strong in the private and the public co-witness conditions. Peer influence on event reports was steady across a large age range (11- to 25-year-olds). PMID:21919594

    Dissociative fugue is a rare disorder which has been described as sudden, unexpected, travel away from home or one's customary place of daily activities, with the inability to recall some or all of one's past. There is no systematic data existing on it and very few cases reported in the literature. Here we report a case of fugue in a young adult male who travelled 8 times away from his home during last 1½ year. He has a loss of memory for episodes with patchy recall of few events. Longest duration of fugue episode was of 1-month. The case describes mode of presentation to hospital and treatment given to restore his identity and reunite him in society and family. PMID:26257491

    This investigation consists of two studies designed to examine perceived fraudulence, its measurement, and the personality traits associated with the experience in young adults. For Study 1, the Perceived Fraudulence Scale (PFS), a new measure constructed for this study, was administered to a sample of 50 college undergraduates, along with several other self-report measures; a semistructured interview and thought-listing exercise were added to provide convergent assessments of perceived fraudulence. Correlational patterns and regression analyses supported the investigators' conceptualization of perceived fraudulence as involving a combination of fraudulent ideation, depressive tendencies, self-criticism, social anxiety, achievement pressures, and self-monitoring skills. Study 2, in which 100 college undergraduates completed several personality questionnaires, replicated the factor structure of the PFS and provided some evidence for the discriminant validity of the construct of perceived fraudulence.

    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

    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

    Purpose The purpose of this study was to determine whether citizens with language impairment understand legal rights as conveyed in Miranda warnings. Method Grisso's Instruments for Assessing Understanding and Appreciation of Miranda Rights (1998) was administered to 34 young adults, half of whom met the diagnostic criteria for specific language impairment (SLI). A correlational analysis of the relationship between language scores and Miranda rights comprehension was conducted, as were tests of differences between individuals with SLI (n = 17) and individuals without SLI. Results Language ability was positively correlated with overall performance on the Miranda measure. As a group, individuals with SLI were significantly poorer than their peers with normal language at defining Miranda vocabulary and applying Miranda rights in hypothetical situations. The group with SLI was also marginally less able to paraphrase Miranda sentences. Conclusion Language impairment limits comprehension of Miranda warnings. As a result, citizens with language impairment are at risk of being denied their constitutional rights. PMID:22230180

    Exposure to bright light appears to be protective against myopia in both animals (chicks, monkeys) and children, but quantitative data on human light exposure are limited. In this study, we report on a technique for quantifying light exposure using wearable sensors. Twenty-seven young adult subjects wore a light sensor continuously for two weeks during one of three seasons, and also completed questionnaires about their visual activities. Light data were analyzed with respect to refractive error and season, and the objective sensor data were compared with subjects’ estimates of time spent indoors and outdoors. Subjects’ estimates of time spent indoors and outdoors were in poor agreement with durations reported by the sensor data. The results of questionnaire-based studies of light exposure should thus be interpreted with caution. The role of light in refractive error development should be investigated using multiple methods such as sensors to complement questionnaires. PMID:25342873

    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

    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.

    Neurological soft signs (NSS) are frequently found in psychiatric disorders of significant neurodevelopmental origin, e.g., in patients with schizophrenia and autism. Yet NSS are also present in healthy individuals suggesting a neurodevelopmental signature of motor function, probably as a continuum between health and disease. So far, little is known about the neural mechanisms underlying these motor phenomena in healthy persons, and it is even less known whether the cerebellum contributes to NSS expression. Thirty-seven healthy young adults (mean age = 23 years) were studied using high-resolution structural magnetic resonance imaging (MRI) and "resting-state" functional MRI at three Tesla. NSS levels were measured using the "Heidelberg Scale." Cerebellar gray matter volume was investigated using cerebellum-optimized voxel-based analysis methods. Cerebellar function was assessed using regional homogeneity (ReHo), a measure of local network strength. The relationship between cerebellar structure and function and NSS was analyzed using regression models. There was no significant relationship between cerebellar volume and NSS (p < 0.005, uncorrected for height, p < 0.05 corrected for spatial extent). Positive associations with cerebellar lobule VI activity were found for the "motor coordination" and "hard signs" NSS domains. A negative relationship was found between lobule VI activity and "complex motor task" domain (p < 0.005, uncorrected for height, p < 0.05 corrected for spatial extent). The data indicate that in healthy young adults, distinct NSS domains are related to cerebellar activity, specifically with activity of cerebellar subregions with known cortical somatomotor projections. In contrast, cerebellar volume is not predictive of NSS in healthy persons. PMID:25708455

    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

    Robust sex differences in some spatial abilities that favor males have raised the question of whether testosterone contributes to those differences. There is some evidence for prenatal organizational effects of testosterone on male-favoring spatial abilities, but not much is known about the role of pubertal testosterone levels on adult cognitive abilities. We studied the association between pubertal testosterone (at age 14) and cognitive performance in young adulthood (at age 21-23), assessing male-favoring, female-favoring, and sex-neutral cognitive domains in a population-based sample of 130 male and 178 female twins. Pubertal testosterone was negatively associated with performance in the Mental Rotation Test in young adult men (r=-.27), while among women no significant associations between testosterone and cognitive measures were detected. The significant association among men remained after controlling for pubertal development. Confirmatory within-family comparisons with one-sided significance testing yielded a negative correlation between twin pair differences in testosterone levels and Mental Rotation Test performances in 35 male twin pairs (r=-.32): the twin brother with higher testosterone performed less well on the Mental Rotation Test. That association was evident in 18 pairs of dizygotic male twin pairs (r=-.42; analysis controlling for shared environmental effects). In contrast, the association of differences was not evident among 17 monozygotic male twin pairs (r=-.07; analysis controlling for shared genetic influences). Results suggest that pubertal testosterone levels are related specifically to male-favoring spatial ability and only among men. Within-family analyses implicated possible shared genetic effects between pubertal testosterone and mental rotation ability. PMID:22520299

    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

    Background Studies of sexuality or sexual behavior in childhood cancer survivors tend to examine relationships or achievement of developmental milestones but not physiological response to cancer or treatment. The purpose of this study is to (1) identify prevalence and risk factors for sexual dysfunction in childhood cancer survivors, and (2) examine the extent to which sexual dysfunction may be associated with health-related quality of life (HRQOL) and psychosocial outcomes. Methods Five hundred ninety-nine survivors age 18-39 years completed standardized measures of sexual functioning, HRQOL, psychological distress and life satisfaction. Descriptive statistics assessed prevalence of sexual symptoms. Bivariate analyses identified correlates of sexual symptoms and examined associations between symptoms and HRQOL/psychosocial outcomes. Results Most survivors appear to be doing well, although 52% of female survivors and 32% of male survivors reported at least “a little of a problem” in one or more areas of sexual functioning. Mean symptom score for females was more than twice that of males. Sexual symptoms were associated with reporting health problems. Significant associations between sexual functioning and HRQOL outcomes were observed, with gender differences in strengths of association suggesting that males find sexual symptoms more distressing than do females. Conclusions While most survivors appear to be doing well in this important life domain, some young adult survivors report sexual concerns. While female survivors may report more sexual symptoms than male survivors, males may experience more distress associated with sexual difficulties. Better specified measures of sexual function, behavior and outcomes are needed for this young adult population. PMID:19862693

    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

    Opposed to large nationally sponsored health initiatives or biobanks, little is known about gathering genetic samples from young adults participating in academic community-based epidemiologic studies of mental health and substance use, especially samples with a large number of minority participants. This study describes our experience of establishing a genetic arm within a longitudinal study of a cohort of young adults (mean age 29, 75 % African American, 58 % female). In total, 75 % of those interviewed in the most recent wave donated a DNA sample (31.6 % blood and 68.4 % saliva) and over 90 % provided consent for storage and sharing. Current smokers were more likely to donate a sample than nonsmokers (adjusted odds ratio (aOR) = 1.59, 95 % confidence interval (CI) = 1.14, 2.22). The odds of obtaining a saliva sample were increased for those who were former cannabis smokers and who drank more regularly, but decreased among participants with less education and a history with drug use. Fewer minorities (aOR = 0.37, 95 % CI = 0.18, 0.75; p = 0.006) and cannabis users (aOR = 0.46, 95 % CI = 0.27, 0.77) consented to sharing their sample with other investigators. Findings also illustrate there are many study parameters that are important in planning biologic collection efforts. Building strong rapport and trust with subjects, minimizing the burden involved by the respondent to obtain a biological sample, offering a choice to provide blood or saliva, and offering an incentive will increase the likelihood of obtaining a sample and, importantly, increase the opportunity to store and share the sample for the future.

    This literature review focuses on what matters to young adults when they access primary care services in the United Kingdom. Patients' access to and experience of primary care services differs across age groups. Existing research has largely focused on the needs and experiences of children, adolescents, and adults. There is some evidence to suggest the views of young adults (aged 18-25 years) that may differ from the views of other age groups, and research has not previously reported specifically on the views of this group of the population. The literature was reviewed to identify the views and priorities of young UK adults regarding primary healthcare provision, and furthermore, to identify those related topics that would benefit from further research. Relevant academic publications and grey literature published from 2000 onwards was reviewed and synthesised. We identified and reported emerging themes that were of importance to young adults in respect of the UK primary care provision. A total of 19 papers met our inclusion criteria. Young adults access primary care services less frequently than other age groups; this may be because of their experience of primary care throughout childhood and adolescence. Five aspects of primary care provision emerged as being of importance to young adults--the accessibility and availability of services, the confidentiality of health-related information, issues relating to communication with healthcare professionals, continuity of care, and behaviours and attitudes expressed towards young adults by healthcare professionals. There is a lack of focus of current research on the expectations, needs, and primary healthcare experiences of young adults. Young adults may hold views that are distinct from other age groups. Further research is needed to better understand the needs of a young adult population as their needs may impact the future use of services. PMID:23092551

    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

    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
