Inter-individual differences in cognitive capacities of young adult rats have largely been ignored. To explore this variability and its neurobiological bases, the relationships between individual differences in working memory and locomotor responses to novelty and to amphetamine were investigated in SD rats. Groups of good and poor learners were isolated, the latter demonstrating a markedly slower learning of the task compared to performant rats, with more perseverations independently to motivational state. They also presented a much higher increase in amphetamine-induced locomotion that remained significant for more than 1h after the injection. These results provide evidence that variability in cognitive capacities can be used to reveal their neurobiological substrates. They open new perspectives to study a possible cognitive origin of addictive behaviors and to investigate the involvement of these inter-individual differences on those observed later in life.

Kefir milk enhances intestinal immunity in young but not old rats.

The adjuvant effect of kefir fermented milk on the mucosal and systemic immune systems was examined in young (6 mo old) and old (26 mo old) rats. Kefir-fed rats consisted of young or old rats consuming kefir-fermented milk ad libitum on a daily basis in addition to the standard diet, for 28 d. Control rats consumed only the standard diet. The rats were immunized intraduodenally with cholera toxin (CT) on d 7 and 21 and killed on d 28. The nonspecific serum immunoglobulin (Ig)A titers in kefir-fed and control rats did not differ in either age group. The serum anti-CT IgA antibody concentrations were significantly higher in the kefir-fed young rats compared with their age-matched controls (+86%, P: < or = 0.05). This difference was associated with enhanced in vitro antibody secretion by cultured lymphocytes isolated from the Peyer's patches and the intestinal lamina propria (+180%, P: < or = 0.05). These enhanced responses were found only in the young rats. However, the nonspecific serum IgG titer was higher (>120%, P: < or = 0.05) and the anti-CT IgG titer was lower (-80%, P: < or = 0.05), in both young and old kefir-fed rats compared with their respective controls. Nevertheless, these results demonstrate that a kefir-supplemented diet affects the intestinal mucosal and systemic immune responses to intraduodenal CT differently in young and old rats. Most importantly, our data suggest that orally administered kefir enhances the specific intestinal mucosal immune response against CT in young adult, but not in senescent rats.

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.

Nerve growth factor (NGF) blocking therapies are an emerging and effective approach to pain management. However, concerns about the potential for adverse effects on the structure and function of the peripheral nervous system have slowed their development. Early studies using NGF antisera in adult rats reported effects on the size and number of neurons in the sympathetic chain ganglia. In the work described here, both young adult (6-8 week) and fully mature (7-8 month) rats were treated with muMab 911, a selective, murine, anti-NGF monoclonal antibody, to determine if systemic exposures to pharmacologically active levels of antibody for 1 month cause loss of neurons in the sympathetic superior cervical ganglia (SCG). State-of-the-art, unbiased stereology performed by two independent laboratories was used to determine the effects of muMab 911 on SCG neuronal number and size, as well as ganglion size. Following muMab 911 treatment, non-statistically significant trends toward smaller ganglia, and smaller and fewer neurons, were seen when routine, nonspecific stains were used in stereologic assessments. However, when noradrenergic neurons were identified using tyrosine hydroxylase (TH) immunoreactivity, trends toward fewer neurons observed with routine stains were not apparent. The only statistically significant effects detected were lower SCG weights in muMab 911-treated rats, and a smaller volume of TH immunoreactivity in neurons from younger rats treated with muMab 911. These results indicate that therapeutically relevant exposures to the anti-NGF monoclonal antibody muMab 911 for 1 month have no effect on neuron numbers within the SCG from young or old adult rats.

What is the central question of this study? Different nerve contributes periods of life are known for their differential sensitivity to interventions, and increased parasympathetic activity affects the development and maintenance of obesity. Thus, we evaluated the involvement of the vagus nerve by performing a vagotomy in young or adult rats that were offered an obesogenic high-fat diet. What is the main finding and its importance? Although the accumulation of adipose tissue decreased in both younger and older groups, the younger rats showed a greater response to the effects of vagotomy in general. In addition to the important role of the parasympathetic activity, we suggest that the vagus nerve contributes to the condition of obesity. Obesity has become a global problem, and this condition develops primarily because of an imbalance between energy intake and expenditure. The high complexity involved in the regulation of energy metabolism results from several factors besides endocrine factors. It has been suggested that obesity could be caused by an imbalance in the autonomous nervous system, which could lead to a condition of high parasympathetic activity in counterpart to low sympathetic tonus. High-fat (HF) diets have been used to induce obesity in experimental animals, and their use in animals leads to insulin resistance, hyperinsulinaemia and high parasympathetic activity, among other disorders. The aim of this work was to evaluate the effects of a vagotomy performed at the initiation of a HF diet at two different stages of life, weaning and adulthood. The vagotomy reduced parasympathetic activity (-32 and -51% in normal fat-fed rats and -43 and -55% in HF diet-fed rats; P < 0.05) and fat depots (-17 and -33%, only in HF diet-fed rats; P < 0.05). High-fat diet-fed rats exhibited fasting hyperinsulinaemia (fivefold higher in young rats and threefold higher in older rats; P < 0.05); however, vagotomy corrected it in younger rats only, and a similar effect was

In the rat, we previously demonstrated that serotonin-enhancing drugs impair cortical spreading depression (CSD) and that l-arginine (arginine) treatment enhances CSD. Here, we investigated the interaction between topical application of the serotonin uptake enhancer tianeptine and systemic arginine administration on CSD. From postnatal day 7-28, female Wistar rats (n=40) received by gavage 300mg/Kg/day arginine (n=20) or water (n=20). Half of the arginine- or water-treated rats underwent CSD recording at 30-40days of age (young), while the other half was recorded at 90-120days (adult). Following baseline recording (four episodes of CSD), we applied tianeptine solution (10mg/ml) to a rectangular portion of the intact dura mater for 10-min and then elicited CSD. This procedure was repeated three times. Compared to baseline values, CSD velocities and amplitudes following tianeptine application increased, and CSD duration decreased significantly (p<0.05) in both young and adult rats, regardless of treatment group. CSD acceleration caused by systemic treatment with arginine is in agreement with previous findings. Topical cortical application of tianeptine replicated the effect of systemic application, suggesting a cortically based mechanism for tianeptine's action. However, the absence of interaction between arginine and tianeptine treatments suggests that they probably act through separate mechanisms. Copyright © 2017 Elsevier B.V. All rights reserved.

The objects of this study were to investigate the effects of massage therapy during early life on postnatal growth, body composition, and skeletal development in juvenile and young adult rats. Massage therapy was performed for 10 minutes daily from D6 to D10 of postnatal life in rat pups (MT, n=24). Body composition, bone area, mineral content, and bone mineral density were measured by dual energy X-ray absorptiometry (DXA); bone strength and intrinsic stiffness on femur shaft were tested by three-point bending; cortical and cancellous bone histomorphometric measurements were performed at D21 and D60. Results were compared to age- and gender-matched controls (C, n=24). D21 body weight, body length, lean mass, and bone area were significantly greater in the MT cohort. Greater bone mineral content was found in male MT rats; bone strength and intrinsic stiffness were greater in D60 MT groups. At D60 MT treatment promoted bone mineralization by increasing trabecular mineral apposition rate in male and endosteal mineral surface in females, and also improved micro-architecture by greater trabeculae width in males and decreasing trabecular separation in females. In summary, massage therapy during early life elicited immediate and prolonged anabolic effects on postnatal growth, lean mass and skeletal developmental in a gender-specific manner in juvenile and young adult rats.

Glucocorticoids have been implicated in nonalcoholic fatty liver diseases (NAFLD). The influence of a palatable diet on the response to stress is controversial. This study explored whether a high-sucrose diet could protect from hepatic steatosis induced by chronic restraint stress in young adult rats. Male Wistar rats aged 21 days were allocated into four groups (n = 6-8 per group): control, chronic restraint stress, 30% sucrose diet, and 30% sucrose diet plus chronic restraint stress. After being exposed to either tap water or sucrose solution during eight weeks, half of the rats belonging to each group were subject or not to repeated restraint stress (1 h per day, 5 days per week) during four weeks. Triacylglycerol (TAG), oxidative stress, activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD-1), infiltration of immune cells, and glycogen amount in the liver were quantified. Serum concentrations of corticosterone and testosterone were also measured. The stressed group showed normal serum concentrations of corticosterone and did not have hepatic steatosis. However, this group showed increased glycogen, inflammation, mild fibrosis, oxidative stress, and a high activity of 11β-HSD-1 in the liver. The group exposed to the high-sucrose diet had lower concentrations of corticosterone, hepatic steatosis and moderate fibrosis. The group subject to high-sucrose diet plus chronic restraint stress showed low concentrations of corticosterone, hepatic steatosis, oxidative stress, and high concentrations of testosterone. Thus, restraint stress and a high-sucrose diet each generate different components of nonalcoholic fatty liver in young adult rats. The combination of both the factors could promote a faster development of NAFLD.

In a previous study, we found that chronic mild stress (CMS) paradigm did not induce anhedonia in young-adult male rats but it reduced their body weight gain. These contrasting results encouraged us to explore other indicators of animal's vulnerability to stress such as anxious-like behaviors, since stress is an etiologic factor also for anxiety. Thus, in this study, we evaluated the vulnerability of these animals to CMS using behavioral tests of depression or anxiety and measuring serum corticosterone. Male Wistar rats were exposed to four weeks of CMS; the animals' body weight and sucrose preference (indicator of anhedonia) were assessed after three weeks, and, after the fourth week, some animals were evaluated in a behavioral battery (elevated plus maze, defensive burying behavior, and forced swimming tests); meanwhile, others were used to measure serum corticosterone. We found that CMS (1) did not affect sucrose preference, immobility behavior in the forced swimming test, or serum corticosterone; (2) decreased body weight gain; and (3) increased the rat's entries into closed arms of the plus maze and the cumulative burying behavior. These data indicate that young male rats' vulnerability to CMS is reflected as poor body weight gain and anxious-like instead of depressive-like behaviors.

There is evidence that cue-induced sucrose seeking progressively increases after cessation of oral sucrose self-administration (incubation of sucrose craving) in both adolescent and adult rats. The synaptic plasticity changes associated with this incubation at different age groups are unknown. We assessed whether incubation of sucrose craving in rats trained to self-administer sucrose as young adolescents, adolescents, or adults is associated with changes in 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)propanoic acid (AMPA)/N-methyl-D-aspartate (NMDA) ratio (a measure of postsynaptic changes in synaptic strength) in nucleus accumbens. Three age groups initiated oral sucrose self-administration training (10 days) on postnatal day (P) 35 (young adolescents), P42 (adolescents), or P70 (adults). They were then tested for cue-induced sucrose seeking (assessed in an extinction test) on abstinence days 1 and 21. Separate groups of rats were trained to self-administer sucrose or water (a control condition), and assessed for AMPA/NMDA ratio in nucleus accumbens on abstinence days 1-3 and 21. Adult rats earned more sucrose rewards, but sucrose intake per body weight was higher in young adolescent rats. Time-dependent increases in cue-induced sucrose seeking (incubation of sucrose craving) were more pronounced in adult rats, less pronounced in adolescents, and not detected in young adolescents. On abstinence day 21, but not days 1-3, AMPA/NMDA ratio in nucleus accumbens were decreased in rats that self-administered sucrose as adults and adolescents, but not young adolescents. Our data demonstrate age-dependent changes in magnitude of incubation of sucrose craving and nucleus accumbens synaptic plasticity after cessation of sucrose self-administration.

Older adults generally experience difficulties with hearing. Age-related changes in the chemistry of central auditory regions, especially the chemistry underlying synaptic transmission between neurons, may be of particular relevance for hearing changes. In this study, we used quantitative microchemical methods to map concentrations of amino acids, including the major neurotransmitters of the brain, in all the major central auditory structures of young (6 months), middle-aged (22 months), and old (33 months old) Fischer 344 x Brown Norway rats. In addition, some amino acid measurements were made for vestibular nuclei, and activities of choline acetyltransferase, the enzyme for acetylcholine synthesis, were mapped in the superior olive and auditory cortex. In old, as compared to young, rats, glutamate concentrations were lower throughout central auditory regions. Aspartate and glycine concentrations were significantly lower in many and GABA and taurine concentrations in some cochlear nucleus and superior olive regions. Glutamine concentrations and choline acetyltransferase activities were higher in most auditory cortex layers of old rats as compared to young. Where there were differences between young and old rats, amino acid concentrations in middle-aged rats often lay between those in young and old rats, suggesting gradual changes during adult life. The results suggest that hearing deficits in older adults may relate to decreases in excitatory (glutamate) as well as inhibitory (glycine and GABA) neurotransmitter amino acid functions. Chemical changes measured in aged rats often differed from changes measured after manipulations that directly damage the cochlea, suggesting that chemical changes during aging may not all be secondary to cochlear damage.

Chronic MDMA induces neurochemical changes in the hippocampus of adolescent and young adult rats: Down-regulation of apoptotic markers.

While hippocampus is a brain region particularly susceptible to the effects of MDMA, the cellular and molecular changes induced by MDMA are still to be fully elucidated, being the dosage regimen, the species and the developmental stage under study great variables. This study compared the effects of one and four days of MDMA administration following a binge paradigm (3×5 mg/kg, i.p., every 2 h) on inducing hippocampal neurochemical changes in adolescent (PND 37) and young adult (PND 58) rats. The results showed that chronic MDMA caused hippocampal protein deficits in adolescent and young adult rats at different levels: (1) impaired serotonergic (5-HT2A and 5-HT2C post-synaptic receptors) and GABAergic (GAD2 enzyme) signaling, and (2) decreased structural cytoskeletal neurofilament proteins (NF-H, NF-M and NF-L). Interestingly, these effects were not accompanied by an increase in apoptotic markers. In fact, chronic MDMA inhibited proteins of the apoptotic pathway (i.e., pro-apoptotic FADD, Bax and cytochrome c) leading to an inhibition of cell death markers (i.e., p-JNK1/2, cleavage of PARP-1) and suggesting regulatory mechanisms in response to the neurochemical changes caused by the drug. The data, together with the observed lack of GFAP activation, support the view that chronic MDMA effects, regardless of the rat developmental age, extends beyond neurotransmitter systems to impair other hippocampal structural cell markers. Interestingly, inhibitory changes in proteins from the apoptotic pathway might be taking place to overcome the protein deficits caused by MDMA. Copyright © 2015 Elsevier Inc. All rights reserved.

Increased potassium intake attenuates the development of salt-dependent hypertension, but the detailed mechanisms of blood pressure (BP) reduction are still unclear. The aims of our study were (i) to elucidate these mechanisms, (ii) to compare preventive potassium effects in immature and adult animals and (iii) to evaluate the therapeutic effects of dietary potassium supplementation in rats with established salt hypertension.   Young (4-week-old) and adult (24-week-old) female salt-sensitive Dahl rats were fed a high-salt diet (5% NaCl) or a high-salt diet supplemented with 3% KCl for 5 weeks. The participation of vasoconstrictor (renin-angiotensin and sympathetic nervous systems) and vasodilator systems [prostanoids, Ca(2+) -activated K(+) channels, nitric oxide (NO)] was evaluated using a sequential blockade of these systems. Preventive potassium supplementation attenuated the development of severe salt hypertension in young rats, whereas it had no effects on BP in adult rats with moderate hypertension. Enhanced sympathetic vasoconstriction was responsible for salt hypertension in young rats and its attenuation for potassium-induced BP reduction. Conversely, neither salt hypertension nor its potassium-induced attenuation were associated with significant changes of the vasodilator systems studied. The relative deficiency of vasodilator action of NO and Ca(2+) -activated K(+) channels in salt hypertensive Dahl rats was not improved by potassium supplementation. The attenuation of enhanced sympathetic vasoconstriction is the principal mechanism of antihypertensive action exerted by preventive potassium supplementation in immature Dahl rats. Dietary potassium supplementation has no preventive effects on BP in adult salt-loaded animals or no therapeutic effects on established salt hypertension in young rats. © 2011 The Authors.

What is the central question of this study? Sleep curtailment in infancy and adolescence may lead to long-term risk for obesity, but the mechanisms involved have not yet been determined. This study examined the immediate and long-term metabolic effects produced by sleep restriction in young rats. What is the main finding and its importance? Prolonged sleep restriction reduced weight gain (body fat stores) in young animals. After prolonged recovery, sleep-restricted rats tended to save more energy and to store more fat, possibly owing to increased gross food efficiency. This could be the first step to understand this association. Sleep curtailment is associated with obesity and metabolic changes in adults and children. The aim of the present study was to evaluate the immediate and long-term metabolic alterations produced by sleep restriction in pubertal male rats. Male Wistar rats (28 days old) were allocated to a control (CTL) group or a sleep-restricted (SR) group. This was accomplished by the single platform technique for 18 h per day for 21 days. These groups were subdivided into the following four time points for assessment: sleep restriction and 1, 2 and 4 months of recovery. Body weight and food intake were monitored throughout the experiment. At the end of each time period, blood was collected for metabolic profiling, and the carcasses were processed for measurement of body composition and energy balance. During the period of sleep restriction, SR animals consumed less food in the home cages. This group also displayed lower body weight, body fat, triglycerides and glucose levels than CTL rats. At the end of the first month of recovery, despite eating as much as CTL rats, SR animals showed greater energy and body weight gain, increased gross food efficiency and decreased energy expenditure. At the end of the second and fourth months of recovery, the groups were no longer different, except for energy gain and gross food efficiency, which remained higher in SR

Awareness is growing that young adults may have distinctive experiences of adult healthcare and that their needs may differ from those of other adult users. In addition, the role of adult health teams in supporting positive transitions from paediatrics is increasingly under discussion. This paper contributes to these debates. It reports a qualitative study of the experiences of young adults - all with complex chronic health conditions - as users of adult health services. Key findings from the study are reported, including an exploration of factors that help to explain interviewees' experiences. Study findings are discussed in the context of existing evidence from young adults in adult healthcare settings and theories of 'young adulthood'. Implications for training and practice are considered, and priorities for future research are identified. © 2014 Royal College of Physicians.

Models using dextran sulfate sodium (DSS) to induce experimental colitis in rodents have been performed mostly in adult animals. For this reason, we aimed to develop a model of colitis in young rats. DSS was administered to 30-day-old rats at concentrations ranging from 0.5 to 5% in drinking water. Young rats were remarkably sensitive to DSS since clinical symptoms rapidly rose with 5% DSS and most animals died after the fifth day. With 1 and 2% DSS, the severity of mucosal lesions was also high on day 7, the animals showing leukocytosis and anemia. At 0.5% DSS, leukocytosis and mild colonic lesions were induced. This concentration of DSS significantly increased myeloperoxidase activity and goblet cell number in the colon, indicating mucosal inflammation. Since food consumption was not reduced by 0.5% DSS, we suggest that this protocol can be used to study the effects of dietary supplements on intestinal inflammatory processes.

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

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

Aripiprazole is a second-generation antipsychotic that is increasingly being prescribed to children and adolescents. Despite this trend, little preclinical research has been done on the neural and behavioral actions of aripiprazole during early development. In the present study, young male and female Sprague-Dawley rats were pretreated with vehicle, haloperidol (1 mg/kg), or aripiprazole (10 mg/kg) once daily on postnatal days (PD) 10–20. After one, four, or eight days (i.e., on PD 21, PD 24, or PD 28), amphetamine-induced locomotor activity and stereotypy, as well as dorsal striatal D2 receptor levels, were measured in separate groups of rats. Pretreating young rats with aripiprazole or haloperidol increased D2 binding sites in the dorsal striatum. Consistent with these results, dopamine supersensitivity was apparent when aripiprazole- and haloperidol-pretreated rats were given a test day injection of amphetamine (2 or 4 mg/kg). Increased D2 receptor levels and altered behavioral responding persisted for at least eight days after conclusion of the pretreatment regimen. Contrary to what has been reported in adults, repeated aripiprazole treatment caused D2 receptor up-regulation and persistent alterations of amphetamine-induced behavior in young rats. These findings are consistent with human clinical studies showing that children and adolescents are more prone than adults to aripiprazole-induced side-effects, including extrapyramidal symptoms.

We have previously reported that a moderately high fat diet increases motivation for sucrose in adult rats. In this study, we tested the motivational, neurochemical, and metabolic effects of the high fat diet in male rats transitioning through puberty, during 5-8 weeks of age. We observed that the high fat diet increased motivated responding for sucrose, which was independent of either metabolic changes or changes in catecholamine neurotransmitter metabolites in the nucleus accumbens. However, AGRP mRNA levels in the hypothalamus were significantly elevated. We demonstrated that increased activation of AGRP neurons is associated with motivated behavior, and that exogenous (third cerebroventricular) AGRP administration resulted in significantly increased motivation for sucrose. These observations suggest that increased expression and activity of AGRP in the medial hypothalamus may underlie the increased responding for sucrose caused by the high fat diet intervention. Finally, we compared motivation for sucrose in pubertal vs. adult rats and observed increased motivation for sucrose in the pubertal rats, which is consistent with previous reports that young animals and humans have an increased preference for sweet taste, compared with adults. Together, our studies suggest that background diet plays a strong modulatory role in motivation for sweet taste in adolescent animals. Published by Elsevier Ltd.

Intermittent alcohol exposure is a common pattern of alcohol consumption among adolescents and alcohol is known to modulate the expression of the endocannabinoid system (ECS), which is involved in metabolism and inflammation. However, it is unknown whether this pattern may have short-term consequences on the ECS in the spleen. To address this question, we examined the plasma concentrations of metabolic and inflammatory signals and the splenic ECS in early adult rats exposed to alcohol during adolescence. A 4-day drinking in the dark (DID) procedure for 4 weeks was used as a model of intermittent forced-alcohol administration (20%, v/v) in female and male Wistar rats, which were sacrificed 2 weeks after the last DID session. First, there was no liver damage or alterations in plasma metabolic parameters. However, certain plasma inflammatory signals were altered according to sex and alcohol exposition. Whereas fractalkine [chemokine (C-X3-C motif) ligand 1] was only affected by sex with lower concentration in male rats, there was an interaction between sex and alcohol exposure in the TNF-α and interleukin-6 concentrations and only female rats displayed changes. Regarding the mRNA and protein expression of the ECS, the receptors and endocannabinoid-synthesizing enzymes were found to be altered with area-specific expression patterns in the spleen. Overall, whereas the expression of the cannabinoid receptor CB1 and the nuclear peroxisome proliferator-activated receptor PPARα were lower in alcohol-exposed rats compared to control rats, the CB2 expression was higher. Additionally, the N-acyl-phosphatidylethanolamine-specific phospholipase D expression was high in female alcohol-exposed rats and low in male alcohol-exposed rats. In conclusion, intermittent alcohol consumption during adolescence may be sufficient to induce short-term changes in the expression of splenic endocannabinoid signaling-related proteins and plasma pro-inflammatory cytokines in young adult rats

Previous studies have shown that a highly enriched cocoa diet affects both intestinal and systemic immune function in young rats. The aim of this study was to elucidate whether diets containing lower amounts of cocoa could also influence the systemic and intestinal humoral immune response. Fecal and serum samples were collected during the study and, at the end, intestinal washes were obtained and mesenteric lymph nodes and small-intestine walls were excised for gene expression assessment. IgA, IgM, IgG1, IgG2a, IgG2b and IgG2c concentrations were quantified in serum whereas S-IgA and S-IgM were determined in feces and intestinal washes. Animals receiving 5 and 10% cocoa for 3 wk showed no age-related increase in serum IgG1 and IgG2a concentrations, and IgG2a values were significantly lower than those in reference animals. Serum IgM was also decreased by the 10% cocoa diet. The 5 and 10% cocoa diets dramatically reduced intestinal S-IgA concentration and modified the expression of several genes involved in IgA synthesis. A diet containing 2% cocoa had no effect on most of the studied variables. The results demonstrate the downregulatory effect of a 5% or higher cocoa diet on the systemic and intestinal humoral immune response in adult rats. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

Ontogenetic differences in the behavioral responsiveness to cocaine have often been attributed to the maturation of dopaminergic elements (e.g., dopamine transporters, D2 High receptors, receptor coupling, etc.). The purpose of this study was to determine whether ontogenetic changes in cocaine pharmacokinetics might contribute to age-dependent differences in behavioral responsiveness. Male and female neonatal (PD 5), preweanling (PD 10 and PD 20), and adult (PD 70) rats were injected (IP) with cocaine or saline and various behaviors (e.g., locomotor activity, forelimb paddle, vertical activity, head-down sniffing, etc.) were measured for 90 min. In a separate experiment, the dorsal striata of young and adult rats were removed at 10 time points (0-210 min) after IP cocaine administration. Peak cocaine values, cocaine half-life, and dopamine levels were determined using HPLC. When converted to percent of saline controls, PD 5 and PD 10 rats were generally more sensitive to cocaine than older rats, but this effect varied according to the behavior being assessed. Peak cocaine values did not differ according to age or sex, but cocaine half-life in brain was approximately 2 times longer in PD 5 and PD 10 rats than adults. Cocaine pharmacokinetics did not differ between PD 20 and PD 70 rats. Differences in the cocaine-induced behavioral responsiveness of very young rats (PD 5 and PD 10) and adults may be attributable, at least in part, to pharmacokinetic factors; whereas, age-dependent behavioral differences between the late preweanling period and adulthood cannot readily be ascribed to cocaine pharmacokinetics.

Permethrin is a Type I (non-cyano) pyrethroid that induces tremors at high concentrations and increases acoustic startle responses (ASR) in adult rodents, however its effects in young rats have been investigated to a limited extent. ASR and tremor were assessed in adult and postnatal day (P)15 Sprague-Dawley rats at oral doses of 60, 90, or 120 mg/kg over an 8 h period. Permethrin increased ASR in adults, regardless of dose, and 20% of the high-dose rats showed tremor at later time points. For the P15 rats all doses induced tremor at all time points, and ASR was increased at 2 h in the 90 and 120 mg/kg groups with a trend in the 60 mg/kg group compared with controls. The 60 mg/kg group showed increased ASR at 4 and 6 h, whereas the 90 mg/kg group showed no differences from the controls at these times. The 120 mg/kg group showed decreased ASR from 4-8 h post-treatment. P15 and adult rats both showed plasma and brain cis- and trans-permethrin increases after dosing. After the same dose of permethrin, P15 rats had greater cis- and trans-permethrin in brain and plasma compared with adults. P15 rats had an increased tremor response compared with adults even at comparable brain permethrin concentrations. For ASR, P15 rats responded sooner and showed a biphasic pattern ranging from increased to decreased response as a function of dose and time, unlike adults that only showed increases. Overall, young rats showed greater effects from permethrin compared with adults.

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

Inhalant abuse in young people is a growing public health concern. We reported previously that acute toluene intoxication in young rats, using a pattern of exposures that approximate abuse patterns of inhalant use in humans, significantly altered neurochemical measures in select brain regions. In this study, adolescent and young adult rats were exposed similarly to an acute (2 × 15 min), high dose (8000 − 12000 ppm) of toluene and high-resolution magic angle spinning proton magnetic resonance spectroscopy (HR-MAS 1H-MRS) was used to assess neurochemical profiles of tissue samples from a number of brain regions collected immediately following solvent exposure. The current investigation focused on N-acetyl-aspartate (NAA), choline-containing compounds, creatine, glutamate, GABA, and glutamine. Contrary to our predictions, no significant alterations were found in levels of NAA, choline, creatine, glutamate, or glutamine in adolescent animals. In contrast to these minimal effects in adolescents, binge toluene exposure altered several neurochemical parameters in young adult rats, including decreased levels of choline and GABA in the frontal cortex and striatum and lowered glutamine and NAA levels in the frontal cortex. One of the more robust findings was a wide-ranging increase in lactate after toluene exposure in adult animals, an effect not observed in adolescents. These age-dependent effects of toluene are distinct from those reported previously in juvenile rats and suggest a developmental difference in vulnerability to the effects of inhalants. Specifically, the results suggest that the neurochemical response to toluene in adolescents is attenuated compared to adults, and imply an association between these neurochemical differences and age-influenced differences in solvent abuse in humans.

Sexual interest and capacity can extend far into later life and result in many positive health outcomes. Yet there is little support for sexual expression in later life, particularly among young adults. This study assessed and compared young adults' explicit and implicit attitudes towards older adult sexuality. A sample of 120 participants (18-24 years; 58% female) completed a self-report (explicit) measure and a series of Implicit Association Tests capturing attitudes towards sexuality among older adults. Despite reporting positive explicit attitudes, young people revealed an implicit bias against the sexual lives of older adults. In particular, young adults demonstrated implicit biases favouring general, as compared to sexual, activities and young adults as compared to older adults. Moreover, the bias favouring general activities was amplified with regard to older adults as compared to younger adults. Our findings challenge the validity of research relying on self-reports of attitudes about older adult sexuality.

Genetic deletion of brain serotonin (5-HT) neurons in mice leads to ventilatory deficits and increased neonatal mortality during development. However, it is unclear if the loss of the 5-HT neurons or the loss of the neurochemical 5-HT led to the observed physiologic deficits. Herein, we generated a mutant rat model with constitutive central nervous system (CNS) 5-HT depletion by mutation of the tryptophan hydroxylase 2 (Tph2) gene in dark agouti (DA(Tph2-/-)) rats. DA(Tph2-/-) rats lacked TPH immunoreactivity and brain 5-HT but retain dopa decarboxylase-expressing raphe neurons. Mutant rats were also smaller, had relatively high mortality (∼50%), and compared with controls had reduced room air ventilation and body temperatures at specific postnatal ages. In adult rats, breathing at rest and hypoxic and hypercapnic chemoreflexes were unaltered in adult male and female DA(Tph2-/-) rats. Body temperature was also maintained in adult DA(Tph2-/-) rats exposed to 4°C, indicating unaltered ventilatory and/or thermoregulatory control mechanisms. Finally, DA(Tph2-/-) rats treated with the 5-HT precursor 5-hydroxytryptophan (5-HTP) partially restored CNS 5-HT and showed increased ventilation (P < 0.05) at a developmental age when it was otherwise attenuated in the mutants. We conclude that constitutive CNS production of 5-HT is critically important to fundamental homeostatic control systems for breathing and temperature during postnatal development in the rat.

The objective of this study was to investigate the effects of zinc deficiency initiated during adolescence on skeletal densitometry, serum markers of bone metabolism, femur minerals and morphometry in young adult rats. Ten-week-old male rats were fed a <1-mg Zn/kg diet (9ZD), a 5-mg Zn/kg diet (9MZD) or a 30-mg Zn/kg diet (9CTL) for up to 9 weeks. Analyses included bone mineral density, serum osteocalcin and C-terminal peptides of type I collagen, serum zinc, femur zinc, calcium and phosphorus, and femur morphometry. Bone mineral density was 14% lower in the spine of 9ZD, but was not altered in the whole body, tibia or femur, or in any of the aforementioned sites in 9MZD, compared to 9CTL. When adjusted for size, spine bone mineral apparent density was still 8% lower in 9ZD than 9CTL. Serum osteocalcin, a marker for bone formation, was approximately 33% lower in 9ZD compared to both 9MZD and 9CTL. The 9ZD and 9MZD had 57% lower femur zinc and 56-88% lower serum zinc concentrations compared to 9CTL. These findings indicate that severe zinc deficiency initiated during adolescence may have important implications for future bone health, especially with regards to bone consolidation in the spine. 2009 S.

Young rats treated daily with intraperitoneal 4-vinylcyclohexene diepoxide (VCD) undergo selective destruction of primordial follicles, resulting in gradual ovarian failure resembling the menopausal transition in women. To determine whether VCD has similar effects on ovaries of older rats, adult and peripubertal Sprague–Dawley rats were injected intraperitoneally daily for 30 d with vehicle or VCD at 40 or 80 mg/kg. Body weight, food intake, complete blood counts, and markers of liver injury and renal function were measured during VCD treatment. Complete gross necropsy and microscopic observations were performed on day 31, and ovarian follicles were counted. At 80 mg/kg, VCD destroyed primordial and primary follicles to a similar extent in both adult and peripubertal animals, although adult rats likely started with fewer follicles and therefore approached follicle depletion. Treatment with VCD did not affect body weight, but food intake was reduced in both adult and peripubertal rats treated with 80 mg/kg VCD. Adult rats treated with 80 mg/kg VCD had neutrophilia and increased BUN and creatinine; in addition, 4 of these rats were euthanized on days 25 or 26 due to peritonitis. VCD treatment did not increase alanine aminotransferase levels, a marker of liver injury, although the 80-mg/kg dose increased liver weights. In conclusion, VCD effectively destroys small preantral follicles in adult Sprague–Dawley rats, making them a suitable model of the menopausal transition of women. However, because adult rats were more sensitive to the irritant properties of VCD, the use of a lower dose should be considered. PMID:19295054

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.

Art has been shown to be an empowering and engaging entity with numerous benefits to vulnerable populations, including the homeless persons and young adults. However, little is known how homeless young adults perceive the use of art as messages that can communicate the danger of initiating or continuing drug and alcohol use. The purpose of this study was to solicit perspectives of homeless, drug-using young adults as to how art can be used to design messages for their peers about the danger of initiating or continuing drug and alcohol use. Qualitative methodology via focus group discussions was utilized to engage 24 homeless young adults enrolled from a drop-in site in Santa Monica, California. The findings revealed support for a myriad of delivery styles, including in-person communication, flyers, music, documentary film, and creative writing. The young adults also provided insight into the importance of the thematic framework of messages. Such themes ranged from empowering and hopeful messages to those designed to scare young homeless adults into not experimenting with drugs. The findings indicate that in addition to messages communicating the need to prevent or reduce drug and alcohol use, homeless young adults respond to messages that remind them of goals and dreams they once had for their future, and to content that is personal, real, and truthful. Our research indicates that messages that reinforce protective factors such as hope for the future and self-esteem may be as important to homeless young adults as information about the risks and consequences of drug use.

Attitudes, social groups, and self-descriptors, including supporting action against the tobacco industry, advertising receptivity, depression, alcohol use, and other factors associated with smoking were tested for associations with smoking behaviors in a 2005 cross-sectional survey of 1528 young adults (aged 18-25 years) from a web-enabled panel. Analyses were conducted in 2007. Being older was associated with current smoking, whereas having some higher education and being African American or Hispanic were negatively associated with smoking. Supporting action against the tobacco industry was negatively associated with smoking (AOR=0.34 [95% CI=0.22, 0.52]). Perceived usefulness of smoking, exposure to smokers, increased perceived smoking prevalence, receptivity to tobacco advertising, binge drinking, and exposure to tobacco advertising in bars and clubs were associated with smoking. Supporting action against the tobacco industry was associated with intentions to quit smoking (AOR=4.43 [95% CI=2.18, 8.60]). Young adults are vulnerable to tobacco-industry advertising. Media campaigns that denormalize the tobacco industry and appeal to young adults appear to be a powerful intervention to decrease young adult smoking.

The objective of the present study was to compare differences between elderly rats and young obesity-induced rats in their activity/inactivity circadian rhythm. The investigation was motivated by the differences reported previously for the circadian rhythms of both obese and elderly humans (and other animals), and those of healthy, young or mature individuals. Three groups of rats were formed: a young control group which was fed a standard chow for rodents; a young obesity-induced group which was fed a high-fat diet for four months; and an elderly control group with rats aged 2.5 years that was fed a standard chow for rodents. Activity/inactivity data were registered through actimetry using infrared actimeter systems in each cage to detect activity. Data were logged on a computer and chronobiological analysis were performed. The results showed diurnal activity (sleep time), nocturnal activity (awake time), amplitude, acrophase, and interdaily stability to be similar between the young obesity-induced group and the elderly control group, but different in the young control group. We have concluded that obesity leads to a chronodisruption status in the body similar to the circadian rhythm degradation observed in the elderly.

The purpose of this study is to investigate how the use of flavored e-cigarettes varies between youth (12-17 years old), young adults (18-29 years old), and older adults (30 + years old). Cross-sectional surveys of school-going youth ( n  = 3907) and young adult college students ( n  = 5482) in Texas, and young adults and older adults ( n  = 6051) nationwide were administered in 2014-2015. Proportions and 95% confidence intervals were used to describe the percentage of e-cigarette use at initiation and in the past 30 days that was flavored, among current e-cigarette users. Chi-square tests were applied to examine differences by combustible tobacco product use and demographic factors. Most e-cigarette users said their first and "usual" e-cigarettes were flavored. At initiation, the majority of Texas school-going youth (98%), Texas young adult college students (95%), and young adults (71.2%) nationwide said their first e-cigarettes were flavored to taste like something other than tobacco, compared to 44.1% of older adults nationwide. Fruit and candy flavors predominated for all groups; and, for youth, flavors were an especially salient reason to use e-cigarettes. Among adults, the use of tobacco flavor at initiation was common among dual users (e-cigarettes + combustible tobacco), while other flavors were more common among former cigarette smokers (P = 0.03). Restricting the range of e-cigarette flavors (e.g., eliminating sweet flavors, like fruit and candy) may benefit youth and young adult prevention efforts. However, it is unclear what impact this change would have on adult smoking cessation.

This study prospectively investigates associations between youth moderate-to-vigorous-intensity physical activity (MVPA) and body composition in young adult women using data from the Dietary Intervention Study in Children (DISC) and the DISC06 Follow-Up Study. MVPA was assessed by questionnaire on 5 occasions between the ages 8 and 18 years and at age 25-29 years in 215 DISC female participants. Using whole body dual-energy x-ray absorptiometry (DXA), overall adiposity and body fat distribution were assessed at age 25-29 years by percent body fat (%fat) and android-to-gynoid (A:G) fat ratio, respectively. Linear mixed effects models and generalized linear latent and mixed models were used to assess associations of youth MVPA with both outcomes. Young adult MVPA, adjusted for other young adult characteristics, was significantly inversely associated with young adult %fat (%fat decreased from 37.4% in the lowest MVPA quartile to 32.8% in the highest (p-trend = 0.02)). Adjusted for youth and young adult characteristics including young adult MVPA, youth MVPA also was significantly inversely associated with young adult %fat (β=-0.40 per 10 MET-hrs/wk, p = .02) . No significant associations between MVPA and A:G fat ratio were observed. Results suggest that youth and young adult MVPA are important independent predictors of adiposity in young women.

Effects of Maternal Behavior Induction and Pup Exposure on Neurogenesis in Adult, Virgin Female Rats

The states of pregnancy and lactation bring about a range of physiological and behavioral changes in the adult mammal that prepare the mother to care for her young. Cell proliferation increases in the subventricular zone (SVZ) of the female rodent brain during both pregnancy and lactation when compared to that in cycling, diestrous females. In the present study, the effects of maternal behavior induction and pup exposure on neurogenesis in nulliparous rats were examined in order to determine whether maternal behavior itself, independent of pregnancy and lactation, might affect neurogenesis. Adult, nulliparous, Sprague-Dawley, female rats were exposed daily to foster young in order to induce maternal behavior. Following the induction of maternal behavior each maternal subject plus females that were exposed to pups for a comparable number of test days, but did not display maternal behavior, and subjects that had received no pup exposure were injected with bromodeoxyuridine (BrdU, 90 mg/kg, i.v.). Brain sections were double-labeled for BrdU and the neural marker, NeuN, to examine the proliferating cell population. Increases in the number of double-labeled cells were found in the maternal virgin brain when compared with the number of double-labeled cells present in non-maternal, pup-exposed nulliparous rats and in females not exposed to young. No changes were evident in the dentate gyrus of the hippocampus as a function of maternal behavior. These data indicate that in nulliparous female rats maternal behavior itself is associated with the stimulation of neurogenesis in the SVZ. PMID:19712726

A cross-sectional study on experiences of young adult carers compared to young adult noncarers: parentification, coping and resilience.

Most young carer studies on parentification, resilience and coping concentrated on child carers up to age 18 years, whereas the group of young adult caregivers (18-24 years) has been neglected. In our study, we focused on these young adult caregivers, who are in a life phase in which young people usually are distancing themselves from their families and are striving for autonomy and freedom. To explore young adult carers' perceptions of parentification, resilience and coping compared to young adult noncarers. Cross-sectional. In 2014/2015, data were collected on 297 healthcare students from a school for vocational education and a university in the Netherlands. A fully structured questionnaire was used. Young adult carers were compared with young adult noncarers on parentification, resilience and coping. Fifty-six students identified themselves as a carer: 40 vocational education students and 16 university students. Carers scored significantly higher than noncarers on three out of six parentification dimensions. No differences were found for resilience and problem-focused coping behaviour, whereas results for emotion-focused coping demonstrated a higher score for the carers compared to the noncarers. Although it is important to take care of the needs of all young carers, special attention should be given to those who are at the start of their adult lives, undergoing extensive changes and taking major decisions on study and career issues. Home-care professionals and school counsellors should be able to recognise this group and their needs and activate support from specialised services and significant others. © 2018 The Authors.

Prior parity positively regulates learning and memory in young and middle-aged rats.

Zimberknopf, Erica; Xavier, Gilberto F; Kinsley, Craig H; Felicio, Luciano F

2011-08-01

Reproductive experience in female rats modifies acquired behaviors, induces long-lasting functional neuroadaptations and can also modify spatial learning and memory. The present study supports and expands this knowledge base by employing the Morris water maze, which measures spatial memory. Age-matched young adult (YNG) nulliparous (NULL; nonmated) and primiparous (PRIM; one pregnancy and lactation) female rats were tested 15 d after the litter's weaning. In addition, corresponding middle-aged (AGD) PRIM (mated in young adulthood so that pregnancy, parturition, and lactation occurred at the same age as in YNG PRIM) and NULL female rats were tested at 18 mo of age. Behavioral evaluation included: 1) acquisition of reference memory (platform location was fixed for 14 to 19 d of testing); 2) retrieval of this information associated with extinction of the acquired response (probe test involving removal of the platform 24 h after the last training session); and 3) performance in a working memory version of the task (platform presented in a novel location every day for 13 d, and maintained in a fixed location within each day). YNG PRIM outperformed NULL rats and showed different behavioral strategies. These results may be related to changes in locomotor, mnemonic, and cognitive processes. In addition, YNG PRIM exhibited less anxiety-like behavior. Compared with YNG rats, AGD rats showed less behavioral flexibility but stronger memory consolidation. These data, which were obtained by using a well-documented spatial task, demonstrate long lasting modifications of behavioral strategies in both YNG and AGD rats associated with a single reproductive experience.

Young adults with acute lymphoblastic leukemia are a distinctive category of patients, with substantial difference in disease biology and response to therapy; hence, they pose unique challenges and issues beyond those faced by children and older adults. Despite inferior survival compared to children, there is growing evidence to suggest that young adults have improved outcomes when treated with pediatric-based approaches. With better supportive care and toxicity management and multidisciplinary team and approach, we have made great improvement in outcomes of young adults with ALL. However, despite significant progress, patients with persistence of minimal residual disease have a poor prognosis. This review discusses current controversies in the management of young adults with ALL, outcomes following pediatric and adult protocols, and the role of allogeneic stem cell transplantation. We also explore recent advances in disease monitoring and highlight our approach to incorporation of novel therapies in the management of young adults with ALL.

Life history strategy and young adult substance use.

Richardson, George B; Chen, Ching-Chen; Dai, Chia-Liang; Swoboda, Christopher M

2014-11-03

This study tested whether life history strategy (LHS) and its intergenerational transmission could explain young adult use of common psychoactive substances. We tested a sequential structural equation model using data from the National Longitudinal Survey of Youth. During young adulthood, fast LHS explained 61% of the variance in overall liability for substance use. Faster parent LHS predicted poorer health and lesser alcohol use, greater neuroticism and cigarette smoking, but did not predict fast LHS or overall liability for substance use among young adults. Young adult neuroticism was independent of substance use controlling for fast LHS. The surprising finding of independence between parent and child LHS casts some uncertainty upon the identity of the parent and child LHS variables. Fast LHS may be the primary driver of young adult use of common psychoactive substances. However, it is possible that the young adult fast LHS variable is better defined as young adult mating competition. We discuss our findings in depth, chart out some intriguing new directions for life history research that may clarify the dimensionality of LHS and its mediation of the intergenerational transmission of substance use, and discuss implications for substance abuse prevention and treatment.

MARRIAGE AND MENTAL HEALTH AMONG YOUNG ADULTS

PubMed Central

Uecker, Jeremy E.

2012-01-01

Marriage is widely thought to confer mental health benefits, but little is known about how this relationship may vary across the life course. Early marriage—which is non-normative—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 = 11,743), I find that married young adults exhibit similar levels of psychological distress as young adults who are in any kind of romantic relationship. Married and engaged young adults report lower rates of drunkenness than others. Married young adults—especially those who first married at age 22–26—report higher life satisfaction than those in other types of relationships or no relationship at all, as well as those who married at younger ages. Explanations for these findings are examined, and their implications are discussed. PMID:22328171

Young adult (2-4 months old) and aged (24-26 months old) Fischer 344 (F344) rats were trained for spatial behavior (locating a hidden escape platform) in a circular water maze. The aged rats showed deficits in both the acquisition and retention of the learned response. Following the behavioral training, hippocampal slices from the rats were prepared. Potentiation of CA1 extracellular, somatic field potentials was studied in vitro following either a short stimulus train (4 pulses) or a longer train (50 pulses). Slices from the aged rats showed less short-term potentiation (124.8 +/- 4.9% baseline, mean +/- S.E.M.) at 1 min following the short train in comparison to slices from the young rats (151.8 +/- 7.5%, P less than 0.05). However, following the longer train, no differences were found between the groups in the degree of either short-term (measured at 1 min after stimulation) or long-term potentiation (measured at 60 min). The amount of potentiation seen at various time points after either train correlated with the behavioral measure of retention. These results indicate that F344 rats exhibit age-related behavioral deficits, and age-related synaptic potentiation deficits in response to short stimulation trains. The correlation between the degree of potentiation (both short-term and long-term) and retention of a behavioral task adds strength to the hypothesis that potentiation mechanisms may underlie memory processes.

Caloric restriction in young rats disturbs hippocampal neurogenesis and spatial learning.

It is widely known that caloric restriction (CR) has benefits on several organic systems, including the central nervous system. However, the majority of the CR studies was performed in adult animals and the information about the consequences on young populations is limited. In this study, we analyzed the effects of young-onset CR, started at 4weeks of age, in the number of neuropeptide Y (NPY)-containing neurons and in neurogenesis of the hippocampal formation, using doublecortin (DCX) and Ki67 as markers. Knowing that CR treatment could interfere with exploratory activity, anxiety, learning and memory we have analyzed the performance of the rats in the open-field, elevated plus-maze and Morris water maze tests. Animals aged 4weeks were randomly assigned to control or CR groups. Controls were maintained in the ad libitum regimen during 2months. The adolescent CR rats were fed, during 2months, with 60% of the amount of food consumed by controls. We have found that young-onset CR treatment did not affect the total number of NPY-immunopositive neurons in dentate hilus, CA3 and CA1 hippocampal subfields and did not change the exploratory activity and anxiety levels. Interestingly, we have found that young-onset CR might affect spatial learning process since those animals showed worse performance during the acquisition phase of Morris water maze. Furthermore, young-onset CR induced alterations of neurogenesis in the dentate subgranular layer that seems to underlie the impairment of spatial learning. Our data suggest that adolescent animals are vulnerable to CR treatment and that this diet is not suitable to be applied in this age phase. Copyright © 2016 Elsevier Inc. All rights reserved.

To determine whether oncology practitioners assess for alcohol consumption rates and usage patterns among young adult cancer survivors, and to determine drinking patterns and frequency of alcoholic beverage consumption among young adult cancer survivors. Retrospective chart review. Two outpatient cancer clinics. 77 young adult survivors of childhood cancer aged 18-30 years. Charts were selected from June to December 2009 and data were extracted using a structured questionnaire. Oncology practitioner assessment of alcohol use and alcohol consumption of young adult cancer survivors. Alcohol screening was conducted for 48 participants. No significant differences were noted in most variables between those not screened for alcohol use and those screened for alcohol use. Of the 48 screened for alcohol use, 30 reported "no use." For the 18 who reported alcohol use, the terms used to describe the frequency varied and were vague. The key finding of the study was that screening and documentation of alcohol consumption was poorly and inconsistently performed in the authors' sample of young adult cancer survivors. Similar to healthy young adults aged 18-30 years, young adult cancer survivors are at a developmental age where it is likely they will engage in unhealthy drinking; therefore, they should be screened for alcohol use and binge drinking. Practitioners can incorporate simple, short questions into health assessment visits that allow them to screen for unhealthy alcohol use.

2012-01-01

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

Bile duct ligation (BDL)-treated rats display cholestasis and liver damages. The potential protective activity of melatonin in young BDL rats in terms of apoptosis, mitochondrial function, and endoplasmic reticulum (ER) homeostasis has not yet been evaluated. Three groups of young male Sprague-Dawley rats were used: one group received laparotomy (Sham), a second group received BDL for two weeks (BDL), and a third group received BDL and intraperitoneal melatonin (100 mg/day) for two weeks (BDL + M). BDL group rats showed liver apoptosis, increased pro-inflamamtory mediators, caspases alterations, anti-apoptotic factors changes, and dysfunction of ER homeostasis. Melatonin effectively reversed apoptosis, mainly through intrinsic pathway and reversed ER stress. In addition, in vitro study showed melatonin exerted its effect mainly through the melatonin 2 receptor (MT2) in HepG2 cells. In conclusion, BDL in young rats caused liver apoptosis. Melatonin rescued the apoptotic changes via the intrinsic pathway, and possibly through the MT2 receptor. Melatonin also reversed ER stress induced by BDL.

In this study age-, circadian rhythm- and methylphenidate administration- effect on open field habituation and object recognition were analyzed. Young and adult male Wistar rats were treated with saline or methylphenidate 2.0 mg/kg for 28 days. Experiments were performed during the light and the dark cycle. Locomotor activity was significantly altered by circadian cycle and methylphenidate treatment during the training session and by drug treatment during the testing session. Exploratory activity was significantly modulated by age during the training session and by age and drug treatment during the testing session. Object recognition memory was altered by cycle at the training session; by age 1.5 h later and by cycle and age 24 h after the training session. These results show that methylphenidate treatment was the major modulator factor on open-field test while cycle and age had an important effect on object recognition experiment.

Cardiorespiratory effects of gap junction blockade in the locus coeruleus in unanesthetized adult rats.

The locus coeruleus (LC) plays an important role in central chemoreception. In young rats (P9 or younger), 85% of LC neurons increase firing rate in response to hypercapnia vs. only about 45% of neurons from rats P10 or older. Carbenoxolone (CARB - gap junction blocker) does not affect the % of LC neurons responding in young rats but it decreases the % responding by half in older animals. We evaluated the participation of gap junctions in the CO2 ventilatory response in unanesthetized adult rats by bilaterally microinjecting CARB (300μM, 1mM or 3mM/100nL), glycyrrhizic acid (GZA, CARB analog, 3mM) or vehicle (aCSF - artificial cerebrospinal fluid) into the LC of Wistar rats. Bilateral gap junction blockade in LC neurons did not affect resting ventilation; however, the increase in ventilation produced by hypercapnia (7% CO2) was reduced by ∼25% after CARB 1mM or 3mM injection (1939.7±104.8mLkg(-1)min(-1) for the aCSF group and 1468.3±122.2mLkg(-1)min(-1) for 1mM CARB, P<0.05; 1939.7±104.8mLkg(-1)min(-1) for the aCSF group and 1540.9±68.4mLkg(-1)min(-1) for the 3mM CARB group, P<0.05) due largely to a decrease in respiratory frequency. GZA injection or CARB injection outside the LC (peri-LC) had no effect on ventilation under any conditions. The results suggest that gap junctions in the LC modulate the hypercapnic ventilatory response of adult rats. Copyright © 2013 Elsevier B.V. All rights reserved.

Maternal fructose exposure (MFE) programs the development of metabolic syndrome (MetS) in young adult offspring. Epidemiological data indicate that MetS may increase the risks of overactive bladder (OAB) symptoms. However, it remains unknown whether MFE programs MetS-associated bladder dysfunction in adult offspring. Using Sprague-Dawley rats, we investigated the effects of MFE during pregnancy and lactation on developmental programming of MetS-associated bladder dysfunction. In addition, next generation sequencing technology was used to identify potential transcripts involved in the programmed bladder dysfunction in adult male offspring to MFE. We found that MFE programmed the MetS-associated OAB symptoms (i.e., an increase in micturition frequency and a shortened mean inter-contractile interval) in young adult male offspring, alongside significant alterations in bladder transcripts, including Chrm2, Chrm3, P2rx1, Trpv4, and Vipr2 gene expression. At protein level, the expressions of M2-, M3-muscarinic and P2X1 receptor proteins were upregulated in the MFE bladder. Functionally, the carbachol-induced detrusor contractility was reduced in the MFE offspring. These data suggest that alterations in the bladder transcripts and impairment of the bladder cholinergic pathways may underlie the pathophysiology of programmed bladder dysfunction in adult offspring to MFE.

Childhood Origins of Young Adult Environmental Behavior.

Evans, Gary W; Otto, Siegmar; Kaiser, Florian G

2018-05-01

Prospective, longitudinal analyses revealed that over a 12-year period from ages 6 to 18, individuals who grew up with mothers with more proenvironmental attitudes engaged in more proenvironmental behavior as young adults. A similar marginal association was uncovered between mothers' proenvironmental behaviors and the proenvironmental behavior of their young adult offspring. Maternal educational attainment, but not political ideology, was also associated with more proenvironmental behavior as children matured. Moreover, childhood time spent outdoors was positively associated with increased environmentally responsible behavior in young adulthood. Interestingly, one's own childhood proenvironmental behavior and attitude, at least as assessed at age 6, bear little on one's eventual proenvironmental behavior as a young adult. Finally, among this set of childhood factors, maternal education and childhood time spent outdoors were independent predictors of positive changes in environmental behavior from early childhood to young adulthood.

Prayer is the most common complementary and alternative intervention used by most Americans. Yet, little is known about the prayer practices of young adults. In this exploratory study, 4 types of prayer practices of 62 young adults (21-30 years old) are described. The 4 different categories of prayer were: contemplative-meditative, ritualistic, petitionary, and colloquial. Participants most often used colloquial prayer practice, that is, asking God to provide guidance or talking to God in their own words. Recommendations for future research are included.

Age-related decline is pervasive in tasks that require explicit learning and memory, but such reduced function is not universally observed in tasks involving incidental learning. It is unknown if habitual attention, involving incidental probabilistic learning, is preserved in older adults. Previous research on habitual attention investigated contextual cuing in young and older adults, yet contextual cuing relies not only on spatial attention but also on context processing. Here we isolated habitual attention from context processing in young and older adults. Using a challenging visual search task in which the probability of finding targets was greater in 1 of 4 visual quadrants in all contexts, we examined the acquisition, persistence, and spatial-reference frame of habitual attention. Although older adults showed slower visual search times and steeper search slopes (more time per additional item in the search display), like young adults they rapidly acquired a strong, persistent search habit toward the high-probability quadrant. In addition, habitual attention was strongly viewer-centered in both young and older adults. The demonstration of preserved viewer-centered habitual attention in older adults suggests that it may be used to counter declines in controlled attention. This, in turn, suggests the importance, for older adults, of maintaining habit-related spatial arrangements. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Young adults, technology, and weight loss: a focus group study.

Stephens, Janna; Moscou-Jackson, Gyasi; Allen, Jerilyn K

2015-01-01

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.

1999-07-01

To determine if oxidation enhances turbidity after proteolysis of rat lens crystallins by the calcium-activated protease calpain (EC 3.4.22.17). Total soluble proteins from young rat lens were hydrolyzed for 24 hr by endogenous lens calpain, and the proteins were further incubated with the oxidant diamide for up to 7 days. Turbidity was measured daily at 405 nm. To measure proteolysis and turbidity in cultured lenses, rat lenses were cultured for 6 days in low calcium medium and diamide. The lenses were then photographed to assess transmission of light. SDS-PAGE and immunoblotting assessed proteolysis of crystallins, alpha-spectrin, and activation of calpain. Appreciable in vitro turbidity occurred in soluble proteins from young rat lenses after proteolysis of crystallins by endogenous calpain. Calpain inhibitor E64, or anti-oxidants DTE and GSH, inhibited this turbidity. On the other hand, the oxidant diamide markedly enhanced calpain-induced turbidity. Cultured rat lenses showed elevated intralenticular calcium and proteolysis of crystallins by calpain, but no nuclear cataract. Addition of diamide to the culture medium caused development of nuclear cataract. Diamide enhanced turbidity only when crystallins were proteolyzed. Oxidation may be one of the factors promoting light scatter and insolubilization after proteolysis. These data are consistent with the hypothesis that proteolysis of crystallins from young rat lens may expose cysteine residues, which are then oxidized, become insoluble and scatter light.

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

Willoughby, Brian J; Hall, Scott S; Goff, Saige

2015-01-01

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

Dental care among young adults with intellectual disability

2015-01-01

Dental care among young adults with intellectual disability (ID) is poorly documented and largely unmet. By using population-based data from the Metropolitan Atlanta Developmental Disabilities Follow-Up Study, we assessed factors associated with at least one or two dental visits per year among young adults with and without ID. Significantly fewer young adults with ID (45%) visited a dentist at least once per year, compared with those without ID (58%). ID severity and the presence of co-occurring developmental disabilities predicted dental care use. Sociodemographics, daily functioning, societal participation, dental services, and dental health factors were examined as predictors of dental care frequency. Our findings can help focus efforts toward improving the frequency of dental care visits among young adults with ID. PMID:23501584

Psychological resilience in young and older adults.

Gooding, P A; Hurst, A; Johnson, J; Tarrier, N

2012-03-01

The goal of the current study was to investigate psychological resilience in the older adults (>64 years) compared with that of the young ones (<26 years). Questionnaire measures of depression, hopelessness, general health and resilience were administered to the participants. The resilience measure comprised three sub-scales of social support, emotional regulation and problem solving. The older adults were the more resilient group especially with respect to emotional regulation ability and problem solving. The young ones had more resilience related to social support. Poor perceptions of general health and low energy levels predicted low levels of resilience regardless of age. Low hopelessness scores also predicted greater resilience in both groups. Experiencing higher levels of mental illness and physical dysfunction predicted high resilience scores especially for the social support resilience scale in the older adults. The negative effects of depression on resilience related to emotional regulation were countered by low hopelessness but only in the young adults. These results highlight the importance of maintaining resilience-related coping skills in both young and older adults but indicate that different psychological processes underlie resilience across the lifespan.

Reproductive Health-Care Utilization of Young Adults Insured as Dependents.

PubMed

Andrasfay, Theresa

2018-05-01

The common practice of sending an explanation of benefits to policyholders may inadvertently disclose sensitive services to the parents of dependents, making confidentiality a potential barrier to reproductive health care. This study compares the reproductive health-care utilization of young adult dependents and young adult policyholders using nationally representative data collected after full implementation of the Affordable Care Act. Data from 2,108 young adults aged 18-25 years in the 2015 National Health Interview Survey were analyzed. Logistic regressions predicted utilization of two preventive services (general doctor visit and flu vaccination) and four reproductive health services (HIV testing, obstetrician/gynecologist visit, hormonal contraceptive use, and Pap testing) from the insurance type of the young adult (dependent, privately insured policyholder, or Medicaid). In unadjusted analyses, young adult dependents had lower utilization of HIV tests than their peers who were privately insured or Medicaid policyholders. Young women dependents had lower utilization of Pap tests than young women on Medicaid. Once controls were included, young adult dependents did not have significantly lower odds of obtaining reproductive health care than privately insured policyholders. Dependent young men still had marginally lower odds of ever having an HIV test (adjusted odds ratio = .65, p = .08) and dependent young women still had marginally lower odds of ever having a Pap test (adjusted odds ratio = .58, p = .06) than comparable Medicaid policyholders. Despite confidentiality concerns, young adults insured as dependents have utilization of several reproductive health services similar to that of comparable young adult policyholders.

Family resilience helps family members successfully overcome adversity, for example, chronic disease or unpleasant situations. However, few studies have identified correlates of family resilience among adolescents/young adults having a parent with cancer. This longitudinal study explored (1) relationships among family resilience, adolescents' perceived stress, and parent-adolescent/young adult communication; (2) trends in family resilience with data collection time; and (3) differences in parent-adolescent/young adult communication by parent gender (ie, father or mother). Participants were teenagers and young adults (12-25 years) with a parent who had cancer. Data were collected using structured questionnaires at 3 times for 4 to 5 months, with 2 months between each collection. Of 96 adolescent/young adult participants enrolled at T1, only 32 completed all measurements at T3. We found that (1) family resilience was negatively associated with adolescents' perceived stress (B = -0.35) and positively associated with adolescent/young adult communication with both the father (B = 0.58) and the mother (B = 0.36), (2) the degree of family resilience at T3 was significantly lower than at T1 (B = -4.79), and (3) at all 3 data collection times, the degree of adolescent/young adult communication was higher with mothers than with fathers, whether the mother had cancer or did not have cancer. Family resilience was positively associated with parent-adolescent/young adult communication and negatively related to perceived stress. Family resilience tended to decline with longer parental survival since cancer diagnosis. We suggest nursing interventions to reduce adolescent/young adult stress and develop optimal parent-adolescent/young adult communication to enhance family resilience.

Sixty-three percent of cancer survivors continue to work, or return to work after treatment. Among this population, work ability and challenges encountered in the workplace by young adult cancer survivors have not been well established. The purposes of the study are to describe what is currently known about work-related issues for young adult cancer survivors diagnosed between ages 15 and 39, to identify gaps in the research literature, and to suggest interventions or improvements in work processes and occupational settings. A narrative review of articles using PubMed, CINAHL, and PsychInfo was conducted without date limitations. Search phrases included young adult cancer survivors, long-term cancer survivors, young adults affected by cancer, further combined with key terms employment, work, and occupationally active. Inclusion criteria for publications were young adult cancer survivors initially diagnosed between the ages of 15 and 39, data about work or employment was presented, and articles written in English. Twenty-three publications met the inclusion criteria. Work-related issues included the potential for reduced work productivity from cancer-changed physical and cognitive functional ability that affected income, and resulted in distress. Coping style, support systems, and changing perspectives about work and life in general were also influential on career decisions among young adult cancer survivors. More research is needed to study interventions to better manage health changes in young adult cancer survivors within the context of the workplace. Since financial hardship has been shown to be especially high among young cancer survivors, employment is essential to ensure payment of cancer-associated costs and continued medical care. While young adult cancer survivors may initially grapple with cancer-related physical and psychosocial changes that impact work productivity or influence choice of occupation, employment appears to enhance overall quality of life.

Lexical fluency tests are frequently used in clinical practice to assess language and executive function. As part of the Spanish normative studies project in young adults (NEURONORMA young adults project), we provide age- and education-adjusted normative data for 3 semantic fluency tasks (animals, fruits and vegetables, and kitchen tools), three formal lexical fluency tasks (words beginning with P, M and R), three excluded-letter fluency tasks (words excluding A, E and S) and a verb fluency task. The sample consisted of 179 participants who are cognitively normal and range in age from 18 to 49 years. Tables are provided to convert raw scores to scaled scores. Age- and education-adjusted scores are provided by applying linear regression techniques. The results show that education impacted most of the verbal fluency test scores, with no effects related to age and only minimal effects related to sex. The norms obtained will be extremely useful in the clinical evaluation of young Spanish adults. Copyright © 2011 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

Quality of life in young adults with cerebral palsy.

Little is known about the quality of life (QOL) of young adults with cerebral palsy. This cross-sectional analysis compares the QOL of a cohort of young Australian adults with CP with a cohort of able-bodied peers to explore the relationship between QOL and impairments, functioning, and social participation. Young adults identified from the Victorian Cerebral Palsy Register were invited to complete a survey about QOL, gross motor function, independence in self-care, and social participation. QOL was assessed with the Quality of Life Instrument for Young Adults (YAQOL). A general population sample of young North American adults, who had completed the YAQOL was selected for comparison. Surveys and consent forms were completed by 335 young adults or their proxies, an overall participation rate of 63% of those located. The mean age of the study participants was 24.7 [s.d = 2.8] years; 51% were male and 49% female. Two hundred and seven (62%) of the 335 participants self-reported their QOL. When compared with the general population sample, self-reporting participants had similar QOL scores for the social relationship and environmental context domains (p > 0.05), while QOL scores were lower for the physical health, psychological well-being, and role function domains (p < 0.001). There was no association between psychological well-being and variables related to body structure and gross motor function in young adults with CP. Contrary to the assumption that young adults with severe CP have low psychosocial well-being, it is apparent that these individuals can have good psychosocial well-being regardless of their disability.

Isolated Systolic Hypertension in Young and Middle-Aged Adults.

PubMed

Yano, Yuichiro; Lloyd-Jones, Donald M

2016-11-01

Young and middle-aged adults (ages ≤50 years) are increasingly prone to stroke, kidney disease, and worsening cardiovascular disease (CVD) mortality. An alarming increase in the prevalence of high blood pressure (BP) may underlie the adverse trend. However, there is often uncertainty in BP management for young and middle-aged adults. Isolated systolic hypertension (ISH) is one such example. Whether ISH in young and middle-aged adults represents "pseudo" or "spurious" hypertension is still being debated. ISH in young and middle-aged adults is a heterogeneous entity; some individuals appear to have increased stroke volume, whereas others have stiffened aortae, or both. One size does not seem to fit all in the clinical management of ISH in young and middle-aged adults. Rather than treating ISH as a monolithic condition, detailed phenotyping of ISH based on (patho)physiology and in the context of individual global cardiovascular risks would seem to be most useful to assess an individual expected net benefit from therapy. This review provides an overview of the current understanding of ISH in young and middle-aged adults, including the prevalence, pathophysiology, and treatment.

Hypothyroidism: age-related influence on cardiovascular nitric oxide system in rats.

This study investigates whether changes in nitric oxide (NO) production participate in the cardiovascular manifestations of hypothyroidism and whether these changes are age-related. Sprague-Dawley rats aged 2 and 18 months old were treated with 0.02% methimazole (wt/vol) during 28 days. Left ventricular function was evaluated by echocardiography. Measurements of arterial blood pressure, heart rate, nitric oxide synthase (NOS) activity and NOS/caveolin-1 and -3 protein levels were performed. Hypothyroidism enhanced the age-related changes in heart function. Hypothyroid state decreased atrial NOS activity in both young and adult rats, associated with a reduction in protein levels of the three NOS isoforms in young animals and increased caveolin (cav) 1 expression in adult rats. Ventricle and aorta NOS activity increased in young and adult hypothyroid animals. In ventricle, changes in NOS activity were accompanied by an increase in inducible NOS isoform in young rats and by an increase in caveolins expression in adult rats. Greater aorta NOS activity level in young and in adult Hypo rats would derive from the inducible and the endothelial NOS isoform, respectively. Thyroid hormones would be one of the factors involved in the modulation of cardiovascular NO production and caveolin-1 and -3 tissue-specific abundance, regardless of age. Hypothyroidism appears to contribute in a differential way to aging-induced changes in the myocardium and aorta tissues. Low thyroid hormones levels would enhance the aging effect on the heart. Age-related changes in NO production participate in the cardiovascular manifestations of hypothyroidism. Copyright © 2012 Elsevier Inc. All rights reserved.

Young adult's attachment style as a partial mediator between maternal functioning and young adult offsprings' functioning.

Ruiz, Sarah K; Harris, Susan J; Martinez, Pedro; Gold, Philip M; Klimes-Dougan, Bonnie

2018-05-01

The quality of our early attachment relationships with primary caregivers is carried forward to new developmental domains, including interpersonal contexts in adulthood. One of the factors that can disrupt early attachment is maternal depression, which may be associated with less responsive care and may impede the development of a secure attachment. Moreover, this disruption in secure attachment may act as a mechanism by which offspring of depressed mothers are more likely to experience their own psychopathology. In this study we predicted that attachment anxiety and avoidance would mediate the relationship between maternal depression diagnosis and functional impairment predicting young adult offspring's functional impairment. This study utilized longitudinal data from 98 families with clinically diagnosed depressed and well mothers, and two of their young adult children, an older and younger sibling (N = 123, Female = 75, Mage = 22.09, SD = 2.57). Mother's and young adult children's functioning was based on clinical ratings on the Global Assessment Scale. Attachment was based on the young adult's self-report on the Experiences in Close Relationships. Results indicate that maternal diagnosis and functional impairment predicted offspring's functional impairment. This relationship was partially mediated through offspring's attachment anxiety, but not attachment avoidance. The mediator and outcome variable were measured concurrently, thus causal implications are limited. Our study provides critical evidence that early experiences with depressed mothers may have influence into young adulthood in typical and atypical domains of development. This work extends our understanding of the impact of early experiences in long-term development, and may have treatment implications for intervening on both maternal and romantic relationships to improve attachment.

The increasing industrial use of nanoparticles (NPs) has raised concerns about their impact on human health. Since aging and exposure to environmental factors are linked to the risk for developing pathologies, we address the question of TiO 2 NPs toxicokinetics in the context of a realistic occupational exposure. We report the biodistribution of titanium in healthy young adults (12-13-week-old) and in elderly rats (19-month-old) exposed to 10mg/m 3 of a TiO 2 nanostructured aerosol 6h/day, 5days/week for 4 weeks. We measured Ti content in major organs using inductively coupled plasma mass spectrometry immediately and up to 180days after the end of exposure. Large amounts of titanium were initially found in lung which were slowly cleared during the post-exposure period. From day 28, a small increase of Ti was found in the spleen and liver of exposed young adult rats. Such an increase was however never found in their blood, kidneys or brain. In the elderly group, translocation to extra-pulmonary organs was significant at day 90. Ti recovered from the spleen and liver of exposed elderly rats was higher than in exposed young adults. These data suggest that TiO 2 NPs may translocate from the lung to extra-pulmonary organs where they could possibly promote systemic health effects. Copyright © 2016.

Reducing Underage and Young Adult Drinking

PubMed Central

Windle, Michael; Zucker, Robert A.

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

2006-09-01

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

To compare the pharmacokinetics of coadministered intraperitoneal ketamine and xylazine in young (8 to 10 wk; n = 6) and old rats (2 to 2.4 y; n = 6), blood samples obtained at 15 and 30 min and 1, 2, and 4 h after drug administration were analyzed by HPLC–tandem mass spectrometry. In both groups, the withdrawal reflex was absent during anesthesia and was present at 1.1 (± 0.2) and 2.6 (± 0.7) h after drug administration in young and old rats, respectively, with the first voluntary movement at 1.5 ± 0.2 and 4.9 ± 1.0 h. Drug availability of ketamine and xylazine was 6.0 and 6.7 times greater, respectively, in old than young rats. The rate constant of elimination of both drugs was greatly decreased and the elimination half-life was significantly greater in old compared with young rats. In conclusion, age and associated factors affect the availability of ketamine and xylazine when coadministered to attain clinical anesthesia, changing the pharmacokinetics of these drugs and prolonging anesthesia duration and recovery times with aging. Compared with their young counterparts, aged rats required much higher doses to attain a similar level of anesthesia. Finally, the long half-life of both ketamine and xylazine, when coadministered to old rats, may be a factor in research protocols because residual plasma concentrations could still be present for as long as 3 and 5 d, respectively, after administration.

Objective Young adulthood represents a critical time to address elevated obesity rates and the risk of early mortality, particularly among people with serious mental illness. Few studies have assessed the benefits of lifestyle interventions targeting weight loss among these young adults. This study examined the impact of the 12-month In SHAPE lifestyle intervention on weight loss and fitness among overweight and obese young adults with serious mental illness (ages 21–30) compared with participants over age 30. Methods Data were combined from three trials of the 12-month In SHAPE program delivered through community mental health centers. In SHAPE includes weekly fitness trainer meetings, a gym membership, and nutrition education. Primary outcomes were weight loss and change in fitness at 12 months. Results Participants (N=194) had a schizophrenia spectrum disorder (53%) or a mood disorder (47%). The overall sample achieved significant weight loss and improved fitness; differences between young adults (N=29) and participants over age 30 (N=165) were not significant. An important finding was that 42% of young adults achieved clinically significant reductions in cardiovascular risk, defined as ≥5% weight loss or improved fitness (>50-m increase on the 6-Minute Walk Test), compared with 54% of adults over age 30 (a non-significant difference between age groups). Conclusions Among persons enrolled in a lifestyle intervention, overweight and obese young adults experienced benefits comparable with those of adults over age 30. Young adults with serious mental illness face high risk of gaining weight, but a meaningful proportion of these individuals can achieve clinically significant cardiovascular risk reduction, thus highlighting the need to promote lifestyle intervention participation in this group.

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

Meerhoff, Gideon F.

2014-01-01

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

Melamine and cyanuric acid (M/CA), when orally administered together to rats, can induce crystal formation within renal tubules and cause acute kidney injury. To investigate the pathomechanism of crystal-induced nephritis, melamine and/or cyanuric acid were administered to 3-week-old (young) and 8-week-old (adult) rats, respectively. Crystal formation, blood urea nitrogen elevation, tubular cell injury and macrophage infiltration were noted in rats fed with M/CA, but not in rats fed with vehicle, melamine or CA alone. These parameters were significantly higher in young rats than those in adult rats fed with M/CA 200 mg/kg body weight (BW) for 3 days. Krüppel-like factor 5 (KLF5) was expressed on distal tubule cells, especially when crystals deposited within the lumens. Both mRNA and protein levels were higher in young rats than those in adult rats fed with M/CA (200 mg/kg BW). KLF5 expression has been shown to modulate renal tissue cytokine production, and we found that proinflammatory cytokines like monocyte chemoattractant protein-1 and interlukin-6 were increased in kidney tissues of young rats fed with M/CA for 3 days. In contrast, interlukin-10, an anti-inflammatory cytokine, was upregulated in kidneys of adult rats fed with M/CA for 3 days. Crystals are prone to deposition in distal tubules of young rats fed with M/CA. M/CA Crystal-related nephritis might be induced by the KLF5 expression, which modulated macrophage recruitment and proinflammatory cytokine production, subsequently leading to renal tubular injury and interstitial inflammation.

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

Environmental enrichment of young adult rats (Rattus norvegicus) in different sensory modalities has long-lasting effects on their ability to learn via specific sensory channels.

PubMed

Dolivo, Vassilissa; Taborsky, Michael

2017-05-01

Sensory modalities individuals use to obtain information from the environment differ among conspecifics. The relative contributions of genetic divergence and environmental plasticity to this variance remain yet unclear. Numerous studies have shown that specific sensory enrichments or impoverishments at the postnatal stage can shape neural development, with potential lifelong effects. For species capable of adjusting to novel environments, specific sensory stimulation at a later life stage could also induce specific long-lasting behavioral effects. To test this possibility, we enriched young adult Norway rats with either visual, auditory, or olfactory cues. Four to 8 months after the enrichment period we tested each rat for their learning ability in 3 two-choice discrimination tasks, involving either visual, auditory, or olfactory stimulus discrimination, in a full factorial design. No sensory modality was more relevant than others for the proposed task per se, but rats performed better when tested in the modality for which they had been enriched. This shows that specific environmental conditions encountered during early adulthood have specific long-lasting effects on the learning abilities of rats. Furthermore, we disentangled the relative contributions of genetic and environmental causes of the response. The reaction norms of learning abilities in relation to the stimulus modality did not differ between families, so interindividual divergence was mainly driven by environmental rather than genetic factors.

Clark, N

1998-12-01

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

Young adults and parental divorce: exploring important issues.

PubMed

Cooney, T M

1988-01-01

This article discusses the potential impact of parental divorce on the lives of young adult offspring. Parental divorce may upset both social and psychological aspects of the transition to adulthood process. The family roles young adults are expected to assume could be altered by the break-up, as could opportunities for particular young adult pursuits, such as advanced education. Heightened adjustment problems also are likely to result, as divorce produces additional life changes during the highly transitional period of early adulthood. Qualitative data from an exploratory study of 39 college students, ages 18-23, illustrate many of the relevant issues. Suggestions for future research are provided.

Kelly, Brian C.; Parsons, Jeffrey T.

2009-01-01

Nonmedical prescription (Rx) drug use has recently increased, particularly among young adults. Using time-space sampling to generate a probability-based sample of club-going young adults (18–29), 400 subjects provided data on Rx drug misuse. Club-going young adults misuse Rx drugs at high rates. An overwhelming majority of the sample indicated lifetime use of pain killers, sedatives, and stimulants. A majority indicated recent pain killer use. Variations by gender and sexuality exist in this population. Young lesbian/bisexual women emerged as the group most likely to abuse Rx drugs. Research into the contexts influencing these patterns is imperative. PMID:17994483

2016-03-01

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. 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. 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. 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.

In contrast to adult rodents, juvenile rodents fail to show relapse following extinction of conditioned fear. Using different retrograde tracers injected into the infralimbic cortex (IL) and the ventral hippocampus (vHPC) in conjunction with c-Fos and parvalbumin (PV) immunochemistry, we investigated the neurocircuitry of extinction in juvenile and adult rats. Regardless of fear extinction or retrieval, juvenile rats had more c-Fos+ neurons in the basolateral amygdala (BLA) compared to adults, and showed a higher proportion of c-Fos+ IL-projecting neurons. Adult rats had more activated vHPC-projecting BLA neurons following extinction compared to retrieval, a difference not observed in juvenile rats. The number of activated vHPC- or IL-projecting BLA neurons was significantly correlated with freezing levels in adult, but not juvenile, rats. We also identified neurons in the BLA that simultaneously project to the IL and vHPC activated in the retrieval groups at both ages. This study provides novel insight into the neural process underlying extinction, especially in the juvenile period. Copyright © 2018 Elsevier B.V. All rights reserved.

Neurodevelopmental and behavioral health disorders commonly occur with epilepsy, yet risk for young adults is unknown. The aim of this study was to determine the distribution and risk characteristics of neurodevelopmental and behavior health comorbidities among young adults with epilepsy compared with those among young adults with migraine and healthy controls. A case-control study examining hospital admission, outpatient, and emergency department (ED) visits for young adults with an ICD-9-CM diagnosis of epilepsy, migraine, or lower extremity fracture (LEF) was conducted. The association of epilepsy, migraine, or LEF with comorbidities was evaluated with univariate and multivariate polytomous logistic regression. From 2000 to 2013, 29,139 young adults ages 19 to 25years were seen in hospitals and EDs for epilepsy (5666), migraine (17,507), or LEF (5966). Young adults with epilepsy had higher proportions of behavioral health comorbidities (51.8%) compared with controls with migraine (37.6%) or LEF (21.6%). In young adults with epilepsy compared with migraine, the increased risk of having any behavioral health comorbidity was 76%, and neurodevelopmental comorbidity was 297%. After adjustment, young adults with epilepsy showed significantly higher odds of each behavioral health comorbidity compared with controls with migraine and LEF. Young adults with epilepsy are particularly susceptible to behavioral health and neurodevelopmental disorders. Results are discussed within the context of transition to adult care.

Osteoporosis knowledge translation for young adults: new directions for prevention programs.

PubMed

Holland, Alyson

2017-08-01

Osteoporosis prevention is heavily reliant on education programs, which are most effective when tailored to their intended audience. Most osteoporosis prevention education is designed for older adults, making application of these programs to younger adults difficult. Designing programs for young adults requires understanding the information-seeking practices of young adults, so that knowledge about osteoporosis can be effectively translated. Individual interviews were conducted with 60 men and women-multiethnic, Canadian young adults-to explore both the sources and types of information they search for when seeking information on nutrition or bone health. The results of this study raised themes related to the sources participants use, to their interests and to ways of engaging young adults. Prevention programs should make use of traditional sources, such as peers, family members and medical professionals, as well as emerging technologies, such as social media. Choice of sources was related to the perceived authority of and trust associated with the source. Messaging should relate to young adult interests, such as fitness and food-topics on which young adults are already seeking information-rather than being embedded within specific osteoporosis awareness materials. Engaging young adults means using relatable messages that are short and encourage small changes. Small gender-based differences were found in the information-seeking interests of participants. Differences related to age were not examined. Creating short, action-oriented messages that are designed to encourage small changes in behaviour and are packaged with information that young adults are actively seeking is more likely to result in active engagement in prevention behaviours.

Preparing childhood cancer survivors for transition to adult care: The young adult perspective.

PubMed

Frederick, Natasha N; Bober, Sharon L; Berwick, Lexie; Tower, Mary; Kenney, Lisa B

2017-10-01

Childhood cancer survivors (CCSs) remain at risk for developing treatment-associated health conditions as they age; however, many do not obtain recommended follow-up, putting them at unnecessary risk for morbidity. Educational interventions targeted at providing survivors with the knowledge and skills necessary for healthcare independence might improve adherence and outcomes as they transition care to the adult medical system. To identify informational needs, educational preferences, and support that young adult CCSs perceive as beneficial for transition from pediatric to adult medical care. Sixteen young adult CCSs (ages 22-39 years) who have transitioned to adult care participated in focus groups led by a trained moderator and analyzed using a thematic analysis approach. Four major themes emerged: (1) education preferences-pediatric oncology provider as the primary source of information and guidance, enhanced by other formats, and early and ongoing engagement in education; (2) family role in transition-desire for independence and acknowledgement of need for ongoing parental support; (3) expectations for adult providers, such as close relationships, open communication, and care coordination; and (4) knowledge deficits regarding disease/treatment history, risk for long-term complications, and navigation of the adult medical system. Transition education as described by young adult CCSs should be a developmentally appropriate process beginning in early adolescents, primarily administered by pediatric oncology providers, and delivered in multiple formats. While healthcare independence is a goal for young adult CCSs, all stakeholders must recognize that families and providers continue to have an important role supporting survivors with transition logistics and medical decision-making. © 2017 Wiley Periodicals, Inc.

2016-06-01

Objectives Tobacco product risk perceptions may influence whether individuals use those products instead of or in addition to regular cigarettes. This study aimed to explore risk perceptions of various tobacco products relative to traditional cigarettes with young adults, a group with higher rates of tobacco use. Method We examined risk perception responses among a nationally representative sample of young adults (age 18-34 years; n = 2,871, including tobacco and non-tobacco users) from the 2011 National Young Adult Health Survey. Results Most (57.8%) respondents believed that e-cigarettes were less risky than cigarettes. Respondents were more likely to rate combustible products hookah (24.5%) and cigars (13.9%) as being less risky compared to noncombustible snus (10%) and other smokeless tobacco (SLT) products (7.1%) relative to cigarettes. Few (2.5%) rated menthol cigarettes as less risky. For e-cigarettes, hookah, and SLT, less risky beliefs were significantly higher among ever or current versus never product users. Between 22% and 33% of all respondents believed that SLT, snus, menthol cigarettes, and cigars were more risky than cigarettes, but differences in this belief between current and nonusers of these products were small and insignificant. Younger young adults were more likely to rate e-cigarettes and hookah as being "less risky" and rate cigars and SLT as being "more risky" than older young adults. Conclusion The public's views of comparative tobacco risk perceptions vary widely by tobacco product type and age-group. While "less risky" perceptions may be associated with product use, perceptions that products are "more risky" than cigarettes may not necessarily dissuade people from their use. © 2015 Society for Public Health Education.

Young and Older Adults' Gender Stereotype in Multitasking

Strobach, Tilo; Woszidlo, Alesia

2015-01-01

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

2013-09-01

We examined postsecondary employment experiences of young adults with an autism spectrum disorder (ASD) and compared these outcomes with those of young adults with different disabilities. Data were from Wave 5 of the National Longitudinal Transition Study-2 (NLTS2), a nationally representative survey of young adults who had received special education services during high school. We examined the prevalence of ever having had, and currently having, a paid job at 21 to 25 years of age. We analyzed rates of full-time employment, wages earned, number of jobs held since high school, and job types. Approximately one-half (53.4%) of young adults with an ASD had ever worked for pay outside the home since leaving high school, the lowest rate among disability groups. Young adults with an ASD earned an average of $8.10 per hour, significantly lower than average wages for young adults in the comparison groups, and held jobs that clustered within fewer occupational types. Odds of ever having had a paid job were higher for those who were older, from higher-income households, and with better conversational abilities or functional skills. Findings of worse employment outcomes for young adults with an ASD suggest that this population is experiencing particular difficulty in successfully transitioning into employment. Research is needed to determine strategies for improving outcomes as these young adults transition into adulthood. Copyright © 2013 American Academy of Child and Adolescent Psychiatry.

Designing programs for young adults requires understanding the information-seeking practices of young adults, so that knowledge about osteoporosis can be effectively translated. Methods: Individual interviews were conducted with 60 men and women—multiethnic, Canadian young adults—to explore both the sources and types of information they search for when seeking information on nutrition or bone health. Results: The results of this study raised themes related to the sources participants use, to their interests and to ways of engaging young adults. Prevention programs should make use of traditional sources, such as peers, family members and medical professionals, as well as emerging technologies, such as social media. Choice of sources was related to the perceived authority of and trust associated with the source. Messaging should relate to young adult interests, such as fitness and food—topics on which young adults are already seeking information—rather than being embedded within specific osteoporosis awareness materials. Engaging young adults means using relatable messages that are short and encourage small changes. Small gender-based differences were found in the information-seeking interests of participants. Differences related to age were not examined. Conclusion: Creating short, action-oriented messages that are designed to encourage small changes in behaviour and are packaged with information that young adults are actively seeking is more likely to result in active engagement in prevention behaviours.

Young adults born preterm have higher levels of cardiometabolic risk factors than their term-born peers. Muscular and cardiorespiratory fitness have important cardiometabolic and other health benefits. We assessed muscular, cardiorespiratory, and self-rated fitness in preterm-born young adults. We studied unimpaired participants of the ESTER (Ennenaikainen syntymä ja aikuisiän terveys [Preterm Birth and Early-Life Programming of Adult Health and Disease]) birth cohort study at age 23.3 (SD: 1.2) years: 139 born early preterm (EPT; <34 weeks), 247 late preterm (LPT; 34-36 weeks), and 352 at term (control group). We measured muscular fitness with the number of modified push-ups performed in 40 seconds and maximal handgrip strength of the dominant hand, cardiovascular fitness with heart rate at the end of a 4-minute step test, and self-rated fitness. Data were analyzed with linear regression. Young adults born EPT (-0.8; 95% confidence interval: -1.5 to -0.1; adjusted for gender, age, and source cohort) and LPT (-0.8; -1.4 to -0.3) performed fewer modified push-ups than controls. Handgrip strength was 23.8 (0.9-46.8) N lower in EPT participants. Cardiorespiratory fitness, measured by submaximal step test, was similar. On a self-rated fitness scale (1-5), the EPT adults reported 0.2 (0.0-0.4) lower scores than controls. After adjustment for early-life confounders, the results remained. They attenuated after further adjustment for mediating factors. Young adults born EPT and LPT had lower muscular fitness than controls, which may predispose them to cardiometabolic and other chronic diseases. Adults born EPT also perceived themselves as less fit than controls. Copyright © 2016 by the American Academy of Pediatrics.

For adolescents and young adults living in high-income countries cancer remains the most common disease-related death. Increasing survival rates and projected longevity are positive outcomes, although long-term consequences of cancer and/or its treatment will likely increase the global burden of cancer. In low and middle-income countries the impact and needs of young adults with cancer are largely unknown and require further attention. However, universal studies have revealed that cancer-related needs for this group are multifactorial, complex and largely unmet. In response to these findings, the body of work on supportive care for young adults with cancer is growing. Yet, there is no published research in the context of the United Kingdom, regarding the role young adults play in managing their supportive cancer care needs. To explore the experience, purpose and meaning of supportive cancer care to young adults recently diagnosed with cancer. Using constructivist grounded theory, data were collected in one to one interviews with eleven young adults (seven women and four men aged 19-24 years) being treated for cancer in two English hospitals. Data were analyzed using open and focused coding, constant comparison, theoretical coding and memoing, and this enabled construction of a subjective theory. Young adults in this study interpreted cancer as an interruption to the events, experiences and tasks forming the biographical work of their adult identity. Data analysis led to the construction of the theory, 'protecting an adult identity: self in relation to a diagnosis of cancer in young adulthood'. This theory arose from three categories: fragility of self, maintaining self in an altered reality and mobilizing external resources. Young adults faced the loss of their early adult identity. Interpreting cancer as a temporary interruption, they sought to re-establish their identity by directly and indirectly managing their supportive care needs. These findings contribute to

(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 D3more » 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.« less

Young adults: vulnerable new targets of tobacco marketing.

PubMed

Biener, Lois; Albers, Alison B

2004-02-01

We examined young adult smoking patterns and receptivity to cigarette advertising to assess vulnerability to tobacco marketing strategies. We obtained data from a telephone survey of 12,072 Massachusetts adults. Smokers aged 18 to 30 years were more likely than older adults to smoke only occasionally and to consume fewer than 10 cigarettes per day. They also were more receptive to cigarette marketing and were more likely to be frequent patrons of bars and clubs. Many young adult smokers are in the initiation phase of smoking and are likely to undergo a transition to either nonsmoking or heavier smoking. If unimpeded by regulation, tobacco promotion in bars and clubs is likely to lead to increased adult smoking prevalence.

The toxicities of 4-nitrophenol and 2,4-dinitrophenol in newborn and young rats was examined and the susceptibility of newborn rats was analyzed in terms of presumed unequivocally toxic and no observed adverse effect levels (NOAELs). In the 18-day repeated dose newborn rat study, 4-nitrophenol was orally given from Day 4 to Day 21 after birth but did not induce any toxicity up to 160 mg/kg in the main study, although it induced death in one of six males at 160 mg/kg, and three of six males and one of six females at 230 mg/kg in a prior dose-finding study. In the 28-day repeated dose oral toxicity study starting at 6 weeks of age, 4-nitrophenol caused the death of most males and females at 1,000 mg/kg but was not toxic at 400 mg/kg except for male rat-specific renal toxicity. As unequivocally toxic levels were considered to be 230 mg/kg/day in newborn rats and 600 to 800 mg/kg/day in young rats, and NOAELs were 110 mg/kg/day in newborn rats and 400 mg/kg/day in young rats, the susceptibility of the newborn to 4-nitrophenol appears to be 2.5 to 4 times higher than that of young animals. In the newborn rat study of 2,4-dinitrophenol, animals died at 30 mg/kg in the dose-finding study and significant lowering of body and organ weights was observed at 20 mg/kg in the main study. In the 28-day young rat study, clear toxic signs followed by death occurred at 80 mg/kg but there was no definitive toxicity at 20 mg/kg. As unequivocally toxic levels and NOAELs were considered to be 30 and 10 mg/kg/day in newborn rats and 80 and 20 mg/kg/day in young rats, respectively, the toxicity of 2,4-dinitrophenol in newborns again seems to be 2 to 3 times stronger than in young rats. Abnormalities of external development and reflex ontogeny in the newborn were not observed with either chemical. Based on these results, it can be concluded that the toxic response in newborn rats is at most 4 times higher than that in young rats, at least in the cases of 4-nitrophenol and 2,4-dinitrophenol.

To guide the development of adolescent health training and the planning of future services, accurate data describing health service use by adolescents and young adults are needed. To describe admission rates for adolescents (12-17 years) and young adults (age 18 years and over) attending a specialist children's hospital over an 8-year period. Specific objectives were to describe the (i) proportion of adolescents and young adults admitted under different specialties; (ii) age range, with emphasis on those 18 years and over; and (iii) proportion of patients admitted to the general adolescent ward. Data on adolescent and young adult admissions to Princess Margaret Hospital (PMH) were collected prospectively from July 2000 to June 2008. Adolescents and young adults accounted for one fifth (range 18-22%) of all admissions to PMH. Over the 8-year period, the number of adolescent and young adult admissions increased from 3935 (54% males) to 4967 (56% males) per year. The proportion admitted to the general adolescent ward ranged from 22% to 36%. The three specialties admitting the most adolescents and young adults were General Surgery (11-13%), Orthopaedics (11-13%) and Oncology/Haematology (10-14%). The age range was: 12-14 years (57-67%); 15-17 (30-39%); 18+ (2-5%). At least 15 patients aged 20 or over were admitted each year, mostly for Dental or Plastic Surgery. Adolescent and young adult health is part of the core business of paediatrics. This should be reflected in the planning of future paediatric services. All trainees require some basic training, regardless of heir specialty area.

Zinc deficiency is associated with multiple clinical complications, including taste disturbance, anorexia, growth retardation, skin changes, and hypogonadism. We investigated the zinc-deficiency-induced morphologic changes in the vallate taste buds of weanling and young adult male Wistar rats. A total of 24 weanling and 30 young adult rats were used. Each age group was further divided into a control group fed a zinc-adequate (50 ppm) diet, a zinc-deficient (< 1 ppm) diet group, and a zinc-adequate pair-fed group who were fed the same amount of food as that taken by the zinc-deficient group. Weanling rats were fed for 4 weeks and young adult rats were fed for 6 weeks. The morphometry and morphologic changes of vallate taste buds were analyzed using light and transmission electron microscopy. Light microscopy revealed no significant difference in papilla size and morphology among the various groups. In both weanling and young adult rats in the zinc-deficient diet and pair-fed groups, the number of taste buds per papilla (per animal) and the average profile area of the taste bud were significantly smaller than those of the corresponding controls (p < 0.05). Ultrastructural changes were seen only in the taste buds of weanling rats fed the zinc-deficient diet, with derangement of the architecture of the taste bud and widening of the intercellular space between taste bud cells. The proportion of type I taste bud cells in the taste buds of weanling rats fed the zinc-deficient diet decreased from 59% to 39%, and that of type II taste bud cells decreased from 25% to 12%. No obvious changes in the ultrastructure of type III taste bud cells were observed. The main effects of zinc deficiency in weanling and young adult rats and in adequate diet pair-fed rats were changes in the number and size of taste buds, and fine structure changes in the taste bud cells, especially during the accelerated growth stage after weaning.

Young adults with familial hypercholesterolemia (FH) are at a critical period for establishing behaviors to promote future cardiovascular health. To examine challenges transitioning to adult care for young adults with FH and parents of FH-affected young adults in the context of 2 developmental tasks, transitioning from childhood to early adulthood and assuming responsibility for self-management of a chronic disorder. Semistructured, qualitative interviews were conducted with 12 young adults with FH and 12 parents of affected young adults from a pediatric subspecialty preventive cardiology program in a northeastern academic medical center. Analyses were conducted using a modified grounded theory framework. Respondents identified 5 challenges: (1) recognizing oneself as a decision maker, (2) navigating emerging independence, (3) prioritizing treatment for a chronic disorder with limited signs and symptoms, (4) managing social implications of FH, and (5) finding credible resources for guidance. Both young adults and parents proposed similar recommendations for addressing these challenges, including the need for family and peer involvement to establish and maintain diet and exercise routines and to provide medication reminders. Systems-level recommendations included early engagement of adolescents in shared decision-making with health care team; providing credible, educational resources regarding FH; and using blood tests to track treatment efficacy. Young adults with FH transitioning to adult care may benefit from explicit interventions to address challenges to establishing healthy lifestyle behaviors and medication adherence as they move toward being responsible for their medical care. Further research should explore the efficacy of recommended interventions. Copyright © 2016 National Lipid Association. Published by Elsevier Inc. All rights reserved.

Body piercing and tattooing are accepted by a growing number of teenagers and young adults as a way of self-expressing. Some authors suggest association between body piercings/tattoos and early sexual initiation, higher number of sexual partners, or risky sexual behaviors. The aim of the study was to evaluate sexual behaviors among young adults with body modifications (BMs)--tattoos and piercings. One hundred twenty young healthy adults, ages between 20 and 35, were included in the population study. The study group was divided into three subgroups: controls (N = 60), adults with tattoos (N = 28), and adults with piercings (N = 32). The research instrument was a self-prepared questionnaire containing 59 questions assessing socioepidemiological parameters, sexual behaviors, incidents of sexual harassment in the past, and self-attractiveness evaluation, as well as questions concerning tattoos and piercings. Socioepidemiological variables and sexual behaviors were compared between subgroups. To assess and describe the correlation between having BM--tattoos and piercing--and sexual behaviors in the population of young adults by using the logistic regression model. Adults with BMs have had their first intercourse statistically earlier and were more sexually active compared with controls. There were no statically significant differences in sexual orientation, sexual preferences, engaging in risky sexual behaviors, frequency of masturbation, and history of sexual abuse between the groups. In contrast, the frequency of sexual intercourses was statistically higher and oral sex was more likely to be a dominant sexual activity in adults with BM compared with controls. The multivariate logistic model revealed that adults with BM were four times less likely to participate in religious practices and twice more likely to have early sexual initiation. Having BM is associated with early sexual initiation and more liberal attitudes toward sexual behaviors but not with engaging in

This study examined support for clean indoor air (CIA) laws among 2044 young adults in Minnesota during 2006 and 2007. Two-thirds of young adult participants supported restaurant CIA laws and 40% supported bar/club CIA laws. A higher proportion of young adults living with CIA laws supported the laws compared with young adults living without them. Nonsmokers, college students, those with nonsmoking friends, and those living with home smoking bans were consistently more supportive of both CIA laws.

This article, based on a study by the Swedish Social Insurance Inspectorate, describes the development of young adults receiving disability benefits due to reduced working capability, and the disability benefit systems in seven European countries; Denmark, Finland, Iceland, Norway, the Netherlands, Sweden, and the UK. This comparative study mainly uses Sweden as a benchmark. Apart from a documentary and legal data collection and analysis, 26 semi-structured interviews were conducted with representatives of the responsible ministries and authorities in the studied countries. In addition, national and European data was collected. There is an increasing trend of young adults, aged 19-29, on disability benefits in all studied countries. The most common diagnosis group among young adults on disability benefits is mental and behavioural disorders, ranging from 58% in the UK to 80% in Denmark. The comparison of the different disability benefit systems shows that there are relatively large national differences in terms of rules and regulations, the handling of disability benefit cases, and offered rehabilitation activities and other measures to support young adults on disability benefits to strengthen their working capability, and hence enable them to approach the labour market in the future. However, it is clear that these countries face similar challenges, and therefore there could be a lot to learn from European exchange of experiences and expertise in this area. This article identifies a number of measures of special interest to study and discusses further with regard to the further development of the Swedish system for disability benefits for young adults.

Reverse correlating trustworthy faces in young and older adults

Éthier-Majcher, Catherine; Joubert, Sven; Gosselin, Frédéric

2013-01-01

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

Bile duct ligation (BDL) model is used to study hepatic encephalopathy accompanied by cognitive impairment. We employed the proteomic analysis approach to evaluate cognition-related proteins in the prefrontal cortex of young BDL rats and analyzed the effect of minocycline on these proteins and spatial memory. BDL was induced in young rats at postnatal day 17. Minocycline as a slow-release pellet was implanted into the peritoneum. Morris water maze test and two-dimensional liquid chromatography-tandem mass spectrometry were used to evaluate spatial memory and prefrontal cortex protein expression, respectively. We used 2D/LC-MS/MS to analyze for affected proteins in the prefrontal cortex of young BDL rats. Results were verified with Western blotting, immunohistochemistry, and quantitative real-time PCR. The effect of minocycline in BDL rats was assessed. BDL induced spatial deficits, while minocycline rescued it. Collapsin response mediator protein 2 (CRMP2) and manganese-dependent superoxide dismutase (MnSOD) were upregulated and nucleoside diphosphate kinase B (NME2) was downregulated in young BDL rats. BDL rats exhibited decreased levels of brain-derived neurotrophic factor (BDNF) mRNA as compared with those by the control. However, minocycline treatment restored CRMP2 and NME2 protein expression, BDNF mRNA level, and MnSOD activity to control levels. We demonstrated that BDL altered the expression of CRMP2, NME2, MnSOD, and BDNF in the prefrontal cortex of young BDL rats. However, minocycline treatment restored the expression of the affected mediators that are implicated in cognition. Copyright © 2017 Elsevier Inc. All rights reserved.

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

Age-related tongue weakness may contribute to swallowing deficits in the elderly. One contributing factor may be an alteration in muscle fiber type properties with aging. However, it is not clear how muscle fiber types within the aged tongue may vary from those found in young adults, or how fiber types may vary across the anteroposterior axis of the extrinsic tongue muscles. We examined myosin heavy chain (MHC) composition of anterior, medial, and posterior sections of the genioglossus muscle (GG) in 10 old male Fischer 344/Brown Norway rats and compared findings to previously reported data from young adult male rats. Significant differences (p< .01) between young adult and old rats were found in the distribution of MHC isoforms along the anteroposterior axis of the muscle. In the anterior, medial, and posterior regions, there was a significantly smaller proportion of type IIb MHC in the old rat GG muscles, while the proportion of type IIx MHC was significantly greater. In the medial region, the proportion of type I MHC was found to be significantly greater in the old rats. Thus, we found a shift to more slowly contracting muscle fibers in the aged rat tongue.

Studying the neural correlates of smoking behaviors in young adulthood is of great importance to improve treatment outcomes. In previous addiction studies, the important roles of the salience network (SN) in drug cue processing and cognitive control have been revealed. Unfortunately, few studies focused on the resting-state functional connectivity and structural integrity abnormalities of SN in young adult smokers, and less is known about its association with smoking behaviors and cognitive control deficits. Thirty-one young male adult smokers and 30 age-, education- and gender-matched nonsmokers participated in this study. The structural and functional connectivity differences of SN were investigated between young adult smokers and nonsmokers by using diffusion tensor imaging (DTI) and resting-state functional connectivity (RSFC), which were then correlated with the smoking behavioral assessments (pack-years and Fagerström Test for Nicotine Dependence (FTND)) as well as impaired cognitive control measured by the Stroop task. Within SN, reduced RSFC and increased fractional anisotropy (FA) were found between the anterior cingulate cortex (ACC) and the right insula in young adult smokers relative to nonsmokers. The RSFC between the ACC and right insula was negatively correlated with the number of errors during the incongruent condition of the Stroop task in young adult smokers. Additionally, the right insula-ACC RSFC was negatively correlated with pack-years in young adult smokers. Our results revealed abnormal RSFC and structural integrity within the SN in young adult smokers, which shed new insights into the neural mechanism of nicotine dependence.

Effects of restricted maternal contact in neonatal rats on sexual behaviour in the adult.

Rats, deprived of maternal contact and nutrition every alternate day starting on day 5 of life, attained a body weight at 45 days of age which was 50% of that of rats which had free access to maternal contact and nutrition. After 55 days of unrestricted food availability the body weight of the neonatally deprived rats was approximately 15% lower than that of the controls. Malnourished female rats showed normal behavioural oestrous cycles and became pregnant and lactated normally as young adults. After ovariectomy they showed higher lordosis quotients in response to treatment with oestradiol benzoate and progesterone than controls but lost less body weight in response to treatment with oestradiol-filled constant-release implants. Malnourished male rats ejaculated less frequently than controls in tests with sexually receptive female rats but this difference disappeared with repeated testing. The malnourished males showed longer ejaculation latencies and had somewhat higher serum concentrations of LH than controls after castration and treatment with testosterone-filled constant-release implants which reduced serum androgen concentrations to about 30% of the intact level. The results show that rats are capable of sustaining a rather severe neonatal nutritional deprivation without losing the capacity for essentially normal mating behaviour in adulthood.

As they mature and become sexually active, more young people face serious health risks. Most face these risks with too little factual information, too little guidance about sexual responsibility, and too little access to health care.

Nowadays, the housing demand of young adults in Indonesia is important issues for the sustainable development of the market. Facing differences of life phases, such as marriage, leaving home after graduation, and new job positioning, young adults become the main segment facing constant housing choice decisions in the housing market. In their particular phase of life, young adults have distinct preferences for housing attributes which bring a great influence on their lives in the future. Data was gathered from a survey questionnaire that was answered by 180 young adults in Indonesia, ranging from age 22-33 years. The findings suggest that the green area and view, location, simplicity, home design, and accessibility are the significant parts as housing attributes for young adults’ housing preferences in Indonesia. The effect of these attributes has many consequences such as security, personalization, mood/ambiance, maintenance, interaction, image, flexibility, environmental, economy, durability, convenience, comfort, and circulation. The biggest group of young adults who prefer comfort as their wanted consequences tend to have high preferences on housing attributes of the green area and view, and simplicity.

The present studies assessed the roles of sex, age, novelty-seeking and plus-maze behavior on cocaine drinking in rats. Cocaine/saccharin solution was available in three daily, 5-hour sessions then a saccharin-only solution was also available in following sessions. In the one-bottle drinking phase, early and late adolescent males, post-natal day 28 (PN28) and PN42, consumed more cocaine/saccharin solution than young adults (PN65), but females did not exhibit significant age differences. Adolescents of both sexes consumed more cocaine/saccharin than adults during choice drinking. Saccharin availability in the two-bottle trials decreased cocaine/saccharin consumption in PN28 and PN65 rats. After a drug-free period, cocaine-stimulated locomotion was lower in cocaine/saccharin drinking than saccharin-only males, indicating tolerance. We tested the hypothesis that individual differences in pre-screened behavioral traits would correlate with cocaine/saccharin consumption in PN28 and PN65 male rats. High locomotor responses to novelty were associated with greater cocaine/saccharin drinking in adults in one-bottle sessions. In the subsequent choice drinking phase, correlations were age-specific. Adolescents with high novelty-induced locomotion and adults that spent less time on open arms of the elevated plus-maze drank more cocaine/saccharin. Thus, behavioral phenotypes correlated with individual differences in cocaine/saccharin consumption in an age-related manner. PMID:18790706

Preventing Smoking Progression in Young Adults: the Concept of Prevescalation.

Villanti, Andrea C; Niaura, Raymond S; Abrams, David B; Mermelstein, Robin

2018-03-10

As adolescents cross the threshold to young adulthood, they encounter more opportunities to engage in or accelerate previously discouraged or prohibited behaviors. Young adults, therefore, are more apt to initiate cigarette smoking and, more importantly, to accelerate their use if they tried and experimented as an adolescent. Preventing the escalation and entrenchment of smoking in the young adult years is critically important to reducing tobacco's long-term health toll. However, traditional interventions for youth have focused on preventing smoking initiation, and interventions for adults have focused on smoking cessation; both have failed to address the needs of young adults. We introduce the concept of "prevescalation" to capture the need and opportunity to prevent the escalation of risk behaviors that typically occur during young adulthood, with a focus on the example of cigarette smoking. Prevescalation negates the notion that prevention has failed if tobacco experimentation occurs during adolescence and focuses on understanding and interrupting transitions between experimentation with tobacco products and established tobacco use that largely occur during young adulthood. However, since risk behaviors often co-occur in young people, the core concept of prevescalation may apply to other behaviors that co-occur and become harder to change in later adulthood. We present a new framework for conceptualizing, developing, and evaluating interventions that better fit the unique behavioral, psychosocial, and socio-environmental characteristics of the young adult years. We discuss the need to target this transitional phase, what we know about behavioral pathways and predictors of cigarette smoking, potential intervention considerations, and research challenges.

The precise correction of refractive error is especially important in young adults. It is unclear whether cycloplegic refraction is necessary in this age group. The purpose of this study was to compare the non-cycloplegic and cycloplegic spherical equivalent (SE) refractive error measured in young adults. This was a prospective study of 1400 eyes (n = 700) of enlisted soldiers aged 18 to 21 years who were consecutively evaluated in an outpatient army ophthalmology clinic. One drop of cyclopentolate 1 % was installed twice 10 min apart, and cycloplegic refraction was performed in both eyes 40 min later using an auto-refractor. The difference between non-cycloplegic and cycloplegic refractive measurements was analyzed. The mean difference in SE between non-cycloplegic and cycloplegic measurements was 0.68 ± 0.83 D (95 % CI, 0.64-0.72). Significantly greater differences were observed in hypermetropes than myopes (1.30 ± 0.90 D versus 0.46 ± 0.68 D, p < 0.001). Moderate hypermetropes (2 to 5 D) demonstrated significantly greater refractive error than mild (0.5 to 2 D) or severe (>5 D) hypermetropes (1.71 ± 1.18 D versus 1.19 ± 0.74 D and 1.16 ± 1.08 D respectively, p < 0.001). Young hypermetropic adults possessed +1 to +2 D of latent hypermetropia. In contrast, young myopic adults revealed pseudomyopia of -0.5 D. Cycloplegic refraction should be performed in young hypermetropic adults complaining of various signs of asthenopia.

The purpose of this study was to determine rates of stimulant/atomoxetine use among teens (aged 12-17 years) and young adults (aged 18-23 years) and to investigate associations in medication use before and after the transition from teen to young adult. Repeated cross-sectional analyses using the nationally representative Medical Expenditure Panel Survey. The sample included all teens and young adults between 2003 and 2012. Within this group, a staggered sample of individuals between 2006 and 2012 born during a 5-year range was used to minimize false positive findings due to temporal trends. The primary outcome was attention deficit hyperactivity disorder (ADHD) medication use (two or more prescriptions and ≥60 tablets). A multivariable logistic regression was utilized to determine associations between ADHD medication use and race/ethnicity and other sociodemographic factors. A total of 62,699 individuals were included between 2003 and 2012. Rates of ADHD medication use increased for both teens (4.2%-6.0%) and young adults (1.2%-2.6%) between 2003-2004 and 2011-2012. In adjusted analysis, blacks, Hispanics, and Asians had lower rates of use compared with whites. The decrease in use among young adults was more pronounced among blacks compared with whites. A usual source of care and health insurance were less common among young adults, and both were associated with ADHD medication use. Although there has been an increase in the use of ADHD medications in both teens and young adults, we found a drop-off in levels of ADHD treatment among young adults when compared with teens. A portion of this decrease appears to be related to race/ethnicity, usual source of care, and health insurance status. Copyright © 2015 Society for Adolescent Health and Medicine.

Expansion of the youth mental health sector has exposed a need for an outcome measure for young adults accessing services. The Strengths and Difficulties Questionnaire (SDQ) is a widely used consumer and carer outcome measure for children and adolescents. The aim of this study was to evaluate the psychometric properties of a young adult SDQ. The young adult SDQ was introduced for routine clinical practice at Eastern Health Child and Youth Mental Health Service (EH-CYMHS), complementing the well-established adolescent and child versions. Data for adolescents (aged 12-17) and young adults (aged 18-25) where both self-report and parent SDQs had been completed at entry point to the service were extracted from a two-year period. Overall, paired cases involved 532 adolescents and 125 young adults. Across both self-report and parent SDQs, a similar pattern of results was found between adolescents and young adults on mean scores, inter-scale correlations, internal consistency, and inter-rater agreement. The findings of the current study support the use of the young adult SDQ in public mental health as an instrument whose psychometric properties, to date, appear consistent with those of the adolescent version. Further investigation is warranted. Copyright © 2018 Elsevier B.V. All rights reserved.

The brain stem contains important nuclei that control cardiovascular function via the sympathetic nervous system (SNS), which is strongly influenced by nitric oxide. Its biological activity is also largely determined by oxygen free radicals. Despite many experimental studies, the role of AT1R-NAD(P)H oxidase-superoxide pathway in NO-deficiency is not yet sufficiently clarified. We determined changes in free radical signaling and antioxidant and detoxification response in the brain stem of young and adult Wistar rats during chronic administration of exogenous NO inhibitors. Young (4 weeks) and adult (10 weeks) Wistar rats were treated with 7-nitroindazole (7-NI group, 10 mg/kg/day), a specific nNOS inhibitor, with N G -nitro-L-arginine-methyl ester (L-NAME group, 50 mg/kg/day), a nonspecific NOS inhibitor, and with drinking water (Control group) during 6 weeks. Systolic blood pressure was measured by non-invasive plethysmography. Expression of genes (AT1R, AT2R, p22phox, SOD and NOS isoforms, HO-1, MDR1a, housekeeper GAPDH) was identified by real-time PCR. NOS activity was detected by conversion of [3H]-L-arginine to [3H]-L-citrulline and SOD activity was measured using UV VIS spectroscopy. We observed a blood pressure elevation and decrease in NOS activity only after L-NAME application in both age groups. Gene expression of nNOS (youngs) and eNOS (adults) in the brain stem decreased after both inhibitors. The radical signaling pathway triggered by AT1R and p22phox was elevated in L-NAME adults, but not in young rats. Moreover, L-NAME-induced NOS inhibition increased antioxidant response, as indicated by the observed elevation of mRNA SOD3, HO-1, AT2R and MDR1a in adult rats. 7-NI did not have a significant effect on AT1R-NADPH oxidase-superoxide pathway, yet it affected antioxidant response of mRNA expression of SOD1 and stimulated total activity of SOD in young rats and mRNA expression of AT2R in adult rats. Our results show that chronic NOS inhibition by two

Background Homeless young adults are a vulnerable population with great healthcare needs. Under the Affordable Care Act, homeless young adults are eligible for Medicaid, in some states, including California. This study assesses homeless young adults' health insurance coverage and healthcare utilization prior to Medicaid expansion. Methods All homeless young adults accessing services at a drop-in center in Venice, CA, were invited to complete a self-administered questionnaire; 70% of eligible clients participated (n = 125). Results Within this majority White, heterosexual, male sample, 70% of homeless young adults did not have health insurance in the prior year, and 39% reported their last healthcare visit was at an emergency room. Past year unmet healthcare needs were reported by 31%, and financial cost was the main reported barrier to receiving care. Multivariable logistic regression found that homeless young adults with health insurance were almost 11 times more likely to report past year healthcare utilization. Conclusions Health insurance coverage is the sole variable significantly associated with healthcare utilization among homeless young adults, underlining the importance of insurance coverage within this vulnerable population. Service providers can play an important role by assisting homeless young adults with insurance applications and facilitating connections with regular sources of health care. PMID:25635142

The incidence of colorectal cancer in adolescent and young adult patients is increasing. However, survival and clinical features of young patients, especially those with stage IV disease, relative to adult patients remain unclear. This retrospective single-institution cohort study was conducted at a tertiary care cancer center. Subjects were 861 consecutive patients who were diagnosed with stage IV colorectal cancer at the age of 15 to 74 years and who were referred to the division of surgery or gastrointestinal oncology at the National Cancer Center Hospital from 1999 to 2013. Overall survival (OS) was investigated and clinicopathological variables were analyzed for prognostic significance. Of these, 66 (8%) were adolescent and young adult patients and 795 (92%) were adult patients. Median survival time was 13.6 months in adolescent and young adult patients and 22.4 months in adult patients, and 5-year OS rates were 17.3% and 20.3%, respectively, indicating significant worse prognosis of adolescent and young adult patients (p = 0.042). However, age itself was not an independent factor associated with prognosis by multivariate analysis. When compared with adult patients, adolescent and young adult patients consisted of higher proportion of the patients who did not undergo resection of primary tumor, which was an independent factor associated with poor prognosis in multivariate analysis. In patients who did not undergo resection (n = 349), OS of adolescent and young adult patients were significantly worse (p = 0.033). Prognoses were worse in adolescent and young adult patients with stage IV colorectal cancer compared to adult patients in Japan, due to a higher proportion of patients who did not undergo resection with more advanced and severe disease, but not due to age itself.

Tobacco industry research on smoking cessation. Recapturing young adults and other recent quitters.

Ling, Pamela M; Glantz, Stanton A

2004-05-01

Smoking rates are declining in the United States, except for young adults (age 18 to 24). Few organized programs target smoking cessation specifically for young adults, except programs for pregnant women. In contrast, the tobacco industry has invested much time and money studying young adult smoking patterns. Some of these data are now available in documents released through litigation. Review tobacco industry marketing research on smoking cessation to guide new interventions and improve clinical practice, particularly to address young adult smokers' needs. Analysis of previously secret tobacco industry documents. Compared to their share of the smoking population, young adult smokers have the highest spontaneous quitting rates. About 10% to 30% of smokers want to quit; light smokers and brand switchers are more likely to try. Tobacco companies attempted to deter quitting by developing products that appeared to be less addictive or more socially acceptable. Contrary to consumer expectations, "ultra low tar" cigarette smokers were actually less likely to quit. Tobacco industry views of young adult quitting behavior contrast with clinical practice. Tobacco marketers concentrate on recapturing young quitters, while organized smoking cessation programs are primarily used by older smokers. As young people have both the greatest propensity to quit and the greatest potential benefits from smoking cessation, targeted programs for young adults are needed. Tobacco marketing data suggest that aspirational messages that decrease the social acceptability of smoking and support smoke-free environments resonate best with young adult smokers' motivations.

Susceptibility to distraction during reading in young, young-old, and old-old adults.

PubMed

McGinnis, Debra

2012-01-01

BACKGROUND/STUDY CONTEXT: Susceptibility to distraction during reading may increase with age, resulting in comprehension errors. Neurological integrity and cognitive reserve are possible covariates of age-related distraction susceptibility. The current study investigated distraction susceptibility in three age groups (young, young-old, and old-old), and examined the covariation patterns of variable sets associated with neurological integrity and cognitive reserve. Participants responded to comprehension questions after reading stories that included semantically related or semantically unrelated distractors. Neurological integrity measures consisted of Mini-Mental State Examination, Selective Reminding, and Category Fluency. Cognitive reserve measures consisted of education and vocabulary. Old-old adults were more likely than young and young-old adults to select distractors when responding to comprehension questions (24.02%, 11.95%, 3.68%, respectively). Age-related distraction variance significantly overlapped neurological variance, and became more transparent after cognitive reserve variance was controlled. This study augments previous age-related distraction research by highlighting (a) the increase in distraction susceptibility in adults over 79, particularly when distractors are semantically related; (b) the influence of age-related neurological integrity on distraction; and (c) the possibility that education and verbal experience may decrease distraction susceptibility, consistent with cognitive reserve frameworks.

This study examined the relationships between cultural identity, severity of hearing loss (HL), and the use of a cochlear implant (CI). One hundred and forty-one adolescents and young adults divided into three groups (deaf with CI, deaf without CI, and hard-of-hearing (HH)) and 134 parents participated. Adolescents and young adults completed questionnaires on cultural identity (hearing, Deaf, marginal, bicultural-hearing, and bicultural-deaf) and communication proficiencies (hearing, spoken language, and sign language). Parents completed a speech quality questionnaire. Deaf participants without CI and those with CI differed in all identities except marginal identity. CI users and HH participants had similar identities except for a stronger bicultural-deaf identity among CI users. Three clusters of participants evolved: participants with a dominant bicultural-deaf identity, participants with a dominant bicultural-hearing identity and participants without a formed cultural identity. Adolescents and young adults who were proficient in one of the modes of communication developed well-established bicultural identities. Adolescents and young adults who were not proficient in one of the modes of communication did not develop a distinguished cultural identity. These results suggest that communication proficiencies are crucial for developing defined identities.

The Stroop Color-Word Interference Test (Stroop) measures cognitive flexibility, selective attention, cognitive inhibition and information processing speed. The Tower of London-Drexel University version test (TOL) assesses higher-order problem solving and executive planning abilities. In this study, as part of the Spanish normative studies project in young adults (NEURONORMA young adults), we present normative data for the Stroop and young adults TOL tests. The sample consisted of 179 participants who are cognitively normal and range in age from 18 to 49 years. Tables are provided to convert raw scores to scaled scores. Scores adjusted for sociodemographic factors were obtained by applying linear regression techniques. No effects were found for age and sex in either test. Educational level impacted most of the Stroop test variables and some of the TOL scores (Total Moves score and Total Initiation Time score). The norms obtained will be extremely useful in the clinical evaluation of young Spanish adults. Copyright © 2011 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

Using Holden's taxonomy of domestic violence (DV) exposure as a guiding framework, the current study examined young adults' diverse DV exposure experiences. Twenty-five young adults (ages 19-25) exposed to father-perpetrated DV during their childhood and adolescence were interviewed using a qualitative descriptive design. Data analyses focused on coercive control exposure through reports of non-physical abuse tactics, types of exposure (e.g., direct, indirect), physical violence exposure (e.g., severity, frequency), and child abuse and harsh parenting practices. DV-exposed young adults were directly and indirectly exposed to physical violence and an array of non-physical abuse tactics toward their mothers. Young adults categorized as having been exposed to coercive controlling violence reported exposure to ongoing, non-physical abuse tactics and more frequent and severe physical violence. These young adults were also more likely to intervene and become victimized during physical violence and reported repeated episodes of child abuse and harsh parenting. Although coercive control appeared to be associated with physical violence and child abuse, generalizations should be made with caution as a few participants exposed to situational conflict were exposed to frequent and severe DV. The findings suggest that DV exposure should be measured in methodologically sophisticated ways to capture the heterogeneity in experiences, with the goal of promoting empirically driven intervention and prevention initiatives that are tailored to individual and family needs. © The Author(s) 2016.

Adolescent Ego-Development Trajectories and Young Adult Relationship Outcomes

Adolescent ego-development trajectories were related to close-relationship outcomes in young adulthood. An adolescent sample completed annual measures of ego development from ages 14 through 17. The authors theoretically determined and empirically traced five ego-development trajectories reflecting stability or change. At age 25, the sample completed a close-relationship interview and consented for two peers to rate the participants’ego resiliency and hostility. Participants who followed the profound-arrest trajectory in adolescence reported more mundane sharing of experiences, more impulsive or egocentric conflict-resolution tactics, and less mature interpersonal understanding in their young adult relationships, and their young adult peers described these participants as more hostile. Participants who attained or maintained higher levels of ego development in adolescence reported more complex sharing of experiences, more collaborative conflict-resolution strategies, and greater interpersonal understanding, and their young adult peers rated them as less hostile and as more flexible.

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

Young adults are an important group for tobacco control interventions because of their high smoking prevalence. In 2014, New Zealand launched a young adult-targeted tobacco control campaign: 'Stop Before You Start'. The evaluation undertaken with young adults (aged 18 to 24 years) showed that the campaign exerted positive impacts on this age group. This study aimed to investigate the collateral effects of this campaign on older adults. Data were collected from a fortnightly survey of adult smokers and recent quitters, where respondents were maintained on a panel and interviewed every fortnight, up to six times. This paper reports on data collected over three consecutive fortnights (540 interviews). Ten measures were used to assess campaign effectiveness (eg, felt regret, tried to quit). After adjusting for recent quit attempt status and socio-demographic characteristics, age differences were not found in any of the outcome variables (aged 25-44 years and 45+ years were compared against 18-24 years). Internationally, little is known about the effectiveness of young adult-targeted tobacco control campaigns. Alongside data from the campaign evaluation with young adults, findings from the current study suggest that this young adult-targeted campaign also created a desirable impact on older adults.

To determine what the trends in stroke mortality have been over 2 decades in young adults. In this cohort study, we analyzed death certificate data for ischemic and hemorrhagic stroke (intracerebral hemorrhage [ICH] and subarachnoid hemorrhage [SAH]) in adults aged 20-44 in the United States for 1989 through 2009, covering approximately 2.2 billion person-years. Poisson regression was used to calculate and compare time trend data between groups and to compare trends in young adults to those in adults over age 45. Mortality from stroke in young adults declined by 35% over the study period, with reductions in all 3 stroke subtypes (ischemic stroke decreased by 15%, ICH by 47%, and SAH by 50%). Black race was a risk factor for all 3 stroke subtypes (relative risk 2.4 for ischemic stroke, 4.0 for ICH, and 2.1 for SAH), but declines in all stroke subtypes were more dramatic in black compared to white participants (p < 0.001 for all stroke subtypes). Although hospitalizations for stroke in young patients have been increasing, the apparent decrease in mortality rates and in racial disparities suggests that recognition and treatment in this group may be improving. © 2014 American Academy of Neurology.

The aim of this study was to analyze the effects of early overnutrition (EON) on the expression of the renin angiotensin aldosterone system (RAAS) components in renal cortex, renal arteries and renal perivascular adipose tissue (PVAT), as well as the vascular response of renal arteries to Angiotensin II (Ang II). On birth day litters were adjusted to twelve (L12-control) or three (L3-overfed) pups per mother. Half of the animals were sacrificed at weaning (21 days old) and the other half at 5 months of age. Ang II-induced vasoconstriction of renal artery segments increased in young overfed rats and decreased in adult overfed rats. EON decreased the gene expression of angiotensinogen (Agt), Ang II receptors AT1 and AT2 and eNOS in renal arteries of young rats, while it increased the mRNA levels of AT-2 and ET-1 in adult rats. In renal PVAT EON up-regulated the gene expression of COX-2 and TNF-α in young rats and the mRNA levels of renin receptor both in young and in adult rats. On the contrary, Ang II receptors mRNA levels were downregulated at both ages. Renal cortex of overfed rats showed increased gene expression of Agt in adult rats and of AT1 in young rats. However the mRNA levels of AT1 were decreased in the renal cortex of overfed adult rats. EON is associated with alterations in the vascular response of renal arteries to Ang II and changes in the gene expression of RAAS components in renal tissue.

Oddleifson, D August; Sawicki, Gregory S

2017-04-01

Adherence to prescribed treatment is a pressing issue for adolescents and young adults with cystic fibrosis (CF). This paper presents two narratives from the thematic analysis of unstructured interviews with 14 adolescents, young adults, and older adults living with CF. Through a new identity-based framework termed recursive perception that draws focus on how an individual perceives how others view them, it explores the social context of adherence and self-care among young adults with CF. It demonstrates that an individual's understanding of self and desire to maintain a certain image for peers can be deeply embedded in adherence and self-care patterns, leading individuals to feel they need to choose between tending to their health needs and living their lives. This suggests that current biomedical innovation in CF care must be complemented with renewed efforts to find effective means to empower young adults with CF to successfully navigate the social challenges of their illness and avoid the pitfalls of nonadherence that can lead to a permanent worsening of their health condition.

Considering quality of care for young adults with diabetes in Ireland

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

The ultimobranchial follicles (UBFs) are considered embryonic remnants from the ultimobranchial body (UBB). They are follicular structures that vary in size and appearance depending on the age of the rat. The main objective of this article was to study the progressive changes in shape, size, and frequency of the UBFs in the postnatal rat, from birth to old-age. To accomplish that objective, a systematic morphometric and incidental study of the UBF has been carried out in 110 Wistar rats of different ages and both sexes, divided into three groups: 1) young rats (5-90-day-old); 2) adult rats (6-15-month-old), and 3) old rats (18-24-month-old). The glands were serially sectioned and immunostained for calcitonin at five equidistant levels. According to our results, UBFs were observed in all thyroid glands but a more exhaustive sampling was occasionally necessary in male rats. In young rats, immature UBFs predominantly appeared whereas in adult rats, mature UBFs with cystic appearance and variable luminal content prevailed. We frequently found spontaneous anomalous UBFs in old rats, which we have termed as "ultimobranchial cystadenomata." Additionally, in young rats, UBF areas significantly increased with age and they were larger when compared to that of normal thyroid follicles. Likewise, in adult rats, UBFs were significantly larger than normal thyroid follicles but only in female rats. In general, UBFs in females were also significantly larger than those found in male rats. Finally, all these differences related to UBFs together with a higher incidence in females of UB cystadenomata suggest a sexual dimorphism in regard to the destiny of these embryonic remnants during postnatal thyroid development.

Career Decision-Making Processes of Young Adults With First-Episode Psychosis.

Boychuk, Christa; Lysaght, Rosemary; Stuart, Heather

2018-05-01

The first episode of psychosis often emerges during young adulthood, when individuals are pursuing important educational and career goals that can become derailed because of the development of major impairments. Past research has neglected the developmental nature of employment and education decisions that young adults with first-episode psychosis make within the context of their lives. The purpose of this grounded theory study was to advance a model of the career decision-making processes of young adults with first-episode psychosis, and the influences that affect their career decision-making. The career decision-making of young adults with first-episode psychosis emerged as a multistaged, iterative process that unfolded over three phases of illness, and was affected by several internal and environmental influences. These findings suggest the phase of illness and career decision-making stage should be considered in future vocational programming for young adults with first-episode psychosis.

2013-09-01

Being diagnosed with cancer as a young adult can lead to significant psychological distress and impaired quality of life. Compared to children and older adults diagnosed with cancer, fewer studies have addressed psychological distress among young adult cancer survivors. This study sought to identify the prevalence of, and factors associated with, distress among young adult cancer survivors (ages 18-39). Young adult cancer survivors (N = 335, mean age = 31.8, women = 68.4%) were recruited from an online research panel and stratified by cohort (time postactive treatment: 0-12, 13-24, and 25-60 months). Participants completed measures assessing demographic and clinical characteristics, global impact of cancer, cancer-related education and work interruption, and cancer-specific distress using the impact of event scale (IES). The mean score on the IES (M = 31.0, range = 0-75) was above the cut point of 20, suggesting clinically elevated distress. Analysis of covariance revealed significant main effects for cohort, global impact and cancer-related education/work interruption, and an interaction between cohort and cancer-related education/work interruption on distress. Although there was no significant effect of education/work interruption on distress for those in the 0-12 month cohort (p = .88), survivors in the 13-24 and 25-60 month cohorts reporting education/work interruption were significantly more distressed than those not reporting education/work interruption in the respective cohorts (p < .05). Young adult cancer survivors face unique challenges. These data underscore the importance of attending to cancer-related distress beyond the completion of treatment and may help inform targeted interventions to prevent or reduce significant distress and related sequelae in this population.

Attractiveness judgments and discrimination of mommies and grandmas: perceptual tuning for young adult faces.

PubMed

Short, Lindsey A; Mondloch, Catherine J; Hackland, Anne T

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.

2015-01-01

Young adults with chronic health conditions can experience barriers to work performance, ability, and their present and future worker roles. Work readiness resources can expand individuals' work skills, abilities, and interests. Five work readiness tools are presented (1) building an occupational profile, (2) generating environmental strategies, (3) on-the-job strategy use, and exploration of online tools (4) O*NET® and (5) O*NET® Interest Profiler, along with two theories (Knowles's Andragogy and Lawton's Ecological Model) to guide tool use. Use of these tools can assist young adults to better manage their health and expand their vocational identities for success at work. These approaches and tools support health professionals, community partners, and vocational organizations in their efforts to help young adults with chronic conditions.

Homeless young adults are a vulnerable population with great healthcare needs. Under the Affordable Care Act, homeless young adults are eligible for Medicaid, in some states, including California. This study assesses homeless young adults' health insurance coverage and healthcare utilization prior to Medicaid expansion. All homeless young adults accessing services at a drop-in center in Venice, CA, were invited to complete a self-administered questionnaire; 70% of eligible clients participated (n = 125). Within this majority White, heterosexual, male sample, 70% of homeless young adults did not have health insurance in the prior year, and 39% reported their last healthcare visit was at an emergency room. Past year unmet healthcare needs were reported by 31%, and financial cost was the main reported barrier to receiving care. Multivariable logistic regression found that homeless young adults with health insurance were almost 11 times more likely to report past year healthcare utilization. Health insurance coverage is the sole variable significantly associated with healthcare utilization among homeless young adults, underlining the importance of insurance coverage within this vulnerable population. Service providers can play an important role by assisting homeless young adults with insurance applications and facilitating connections with regular sources of health care. © The Author 2015.

2006-12-01

To describe food-preparation behaviors, cooking skills, resources for preparing food, and associations with diet quality among young adults. Cross-sectional analyses were performed in a sample of young adults who responded to the second wave of a population-based longitudinal study. Measures pertaining to food preparation were self-reported and dietary intake was assessed by a food frequency questionnaire, both by a mailed survey. Males (n = 764) and females (n = 946) ages 18 to 23 years. Cross-tabulations and chi2 tests were used to examine associations between food preparation, skills/resources for preparing foods, and characteristics of young adults. Mixed regression models were used to generate expected probabilities of meeting the Healthy People 2010 dietary objectives according to reported behaviors and skills/resources. Food-preparation behaviors were not performed by the majority of young adults even weekly. Sex (male), race (African American), and living situation (campus housing) were significantly related to less frequent food preparation. Lower perceived adequacy of skills and resources for food preparation was related to reported race (African American or Hispanic) and student status (part-time or not in school). The most common barrier to food preparation was lack of time, reported by 36% of young adults. Young adults who reported frequent food preparation reported less frequent fast-food use and were more likely to meet dietary objectives for fat (P < 0.001), calcium (P < 0.001), fruit (P < 0.001), vegetable (P < 0.001), and whole-grain (P = 0.003) consumption. To improve dietary intake, interventions among young adults should teach skills for preparing quick and healthful meals.

Self-management in young adults with bipolar disorder: Strategies and challenges.

2017-02-01

Early adoption of effective self-management strategies for bipolar disorder (BD) results in better clinical outcomes and increased quality of life. Therefore, facilitation of these strategies in young adults who are early in their illness course is vital. However, an understanding of self-management practices and needs of young adults with BD is lacking. This study explores young adult's perspectives of disorder self-management practices and challenges. Young adults with BD completed an online survey about disorder management strategies and challenges. Self-management was investigated through self-report and ratings of literature-derived strategies. Results were analysed using descriptive statistics and qualitative thematic analysis. Eighty-nine participants aged 18-30 (M=24.4; SD=3.9) completed the survey. Adherence to treatment, disorder psychoeducation, and sleep-management were the strategies rated most helpful. Six participant-reported self-management strategies were identified (1) Maintaining a healthy lifestyle; (2) Treatment attendance and adherence; (3) Participation in meaningful activities; (4) Engagement with social support; (5) Meditation and relaxation practices; and (6) Symptom monitoring. The most common self-management challenges experienced by young adults concerned the nature of the disorder, interpersonal relationships, and stigma. Participants likely represent a sub-set of young adults engaged with healthcare and therefore may not be representative of the population. Strategies reported vital by those successfully managing their disorder are not adequately utilised by young adults with BD. Both differences in strategy use and perceived self-management challenges represent important areas of clinical support and intervention. This increased understanding will help facilitate self-management skill development in this population. Copyright © 2016 Elsevier B.V. All rights reserved.

Published data on the comparative achievement of The Kidney Disease Dialysis Outcome Quality Initiative (KDOQI) recommended clinical performance targets between children and young adults on dialysis are scarce. To characterize the achievement of KDOQI targets among children (<18 years) and young adults (18-24 years) with prevalent end stage renal disease (ESRD), we performed a cross-sectional analysis of data collected by the Mid-Atlantic Renal Coalition, in conjunction with the 2007 and 2008 ESRD Clinical Performance Measures Projects. Data on all enrolled pediatric dialysis patients, categorized into three age groups (0-8, 9-12, 13-17 years), and on a random sample of 5% of patients ≥ 18 years in ESRD Network 5 were examined for two study periods: hemodialysis (HD) data were collected from October to December 2006 and from October to December 2007 and peritoneal dialysis (PD) data were collected from October 2006 to March 2007 and from October 2007 to March 2008. In total, 114 unique patients were enrolled the study, of whom 41.2% (47/114) were on HD and 58.8% (67/114) on PD. Compared to the pediatric patients, young adults were less likely to achieve the KDOQI recommended serum phosphorus levels and serum calcium × phosphorus product values, with less than one-quarter demonstrating values at or below each goal. Multivariate analysis revealed that both young adults and 13- to 17-year-olds were less likely to achieve target values for phosphorus [young adults: odds ratio (OR) 0.04, 95% confidence interval (95% CI) 0.01-0.19, p < 0.001; 13- to 17-year-olds: OR 0.17, 95% CI 0.04-0.77, p = 0.02] and calcium × phosphorus product (young adults: OR 0.01, 95% CI 0.002-0.09, p < 0.001; 13- to 17-year-olds: OR 0.09, 95% CI 0.02-0.56, p = 0.01) than younger children. In summary, there are significant differences in clinical indices between pediatric and young adult ESRD patients.

Young adults: beloved by food and drink marketers and forgotten by public health?

PubMed

Freeman, Becky; Kelly, Bridget; Vandevijvere, Stefanie; Baur, Louise

2016-12-01

Young adults are a highly desirable target population for energy-dense, nutrient-poor (EDNP) food and beverage marketing. But little research, resources, advocacy and policy action have been directed at this age group, despite the fact that young adults are gaining weight faster than previous generations and other population groups. Factors such as identity development and shifting interpersonal influences differentiate young adulthood from other life stages and influence the adoption of both healthy and unhealthy eating behaviours. EDNP food and beverage marketing campaigns use techniques to normalize brands within young adult culture, in particular through online social media. Young adults must be a priority population in future obesity prevention efforts. Stronger policies to protect young adults from EDNP food and beverage marketing may also increase the effectiveness of policies that are meant to protect younger children. Restrictions on EDNP food and beverage marketing should be extended to include Internet-based advertising and also aim to protect vulnerable young adults. © The Author 2015.

Elderly individuals compose a large percentage of the world population; however, few studies have addressed the efficacy of current medical countermeasures (MCM) against the effects of chemical warfare nerve agent exposure in aged populations. We evaluated the efficacy of the anticonvulsant diazepam in an old adult rat model of soman (GD) poisoning and compared the toxic effects to those observed in young adult rats when anticonvulsant treatment is delayed. After determining their respective median lethal dose (LD50) of GD, we exposed young adult and old adult rats to an equitoxic 1.2 LD50 dose of GD followed by treatment with atropine sulfate and the oxime HI-6 at one minute after exposure, and diazepam at 30 minutes after seizure onset. Old adult rats that presented with status epilepticus were more susceptible to developing spontaneous recurrent seizures (SRS). Neuropathological analysis revealed that in rats of both age groups that developed SRS, there was a significant reduction in the density of mature neurons in the piriform cortex, thalamus, and amygdala, with more pronounced neuronal loss in the thalamus of old adult rats compared to young adult rats. Furthermore, old adult rats displayed a reduced density of cells expressing glutamic acid decarboxylase 67, a marker of GABAergic interneurons, in the basolateral amygdala and piriform cortex, and a reduction of astrocyte activation in the piriform cortex. Our observations demonstrate the reduced effectiveness of current MCM in an old adult animal model of GD exposure and strongly suggest the need for countermeasures that are more tailored to the vulnerabilities of an aging population.

Mental health in young adults and adolescents - supporting general physicians to provide holistic care.

PubMed

Jurewicz, Izabela

2015-04-01

In the era of an ageing population, young adults on medical wards are quite rare, as only 12% of young adults report a long-term illness or disability. However, mental health problems remain prevalent in the younger population. In a recent report, mental health and obesity were listed as the most common problems in young adults. Teams set up specifically for the needs of younger adults, such as early intervention in psychosis services are shown to work better than traditional care and have also proven to be cost effective. On the medical wards, younger patients may elicit strong emotions in staff, who often feel protective and may identify strongly with the young patient's suffering. In order to provide holistic care for young adults, general physicians need to recognise common presentations of mental illness in young adults such as depression, deliberate self-harm, eating disorders and substance misuse. Apart from treating illness, health promotion is particularly important for young adults. © 2015 Royal College of Physicians.

2002-12-01

Repeated dose toxicity of 3-aminophenol was examined on oral administration to newborn and young rats, and susceptibility was analyzed in terms of the no observed adverse effect level (NOAEL) and the unequivocally toxic level. In the 18-day newborn rat study, starting at day 4 after birth, tremors and depression of body weight gain were observed, as well as hypertrophy of thyroid follicular epithelial cells and increases of relative liver and kidney weights at 240 mg/kg. Increase of relative liver weights in males and decrease of blood sugar in females without any histopathological changes at 80 mg/kg were not considered to be adverse effects. No chemical-related changes were observed at 24 mg/kg. Abnormalities of external development and reflex ontogeny in the newborn were not observed. In the 28-day study, starting at 5 weeks of age, depression of body weight gain, tremors, anemia, and liver, kidney and thyroid toxicity were observed at 720 mg/kg. Although slight pigmentation in the renal proximal tubular epithelium was observed in females at 240 mg/kg, this was not considered to be an adverse effect because of the lack of changes in related toxicological parameters. It was concluded that the NOAEL is 80 mg/kg/day in newborn rats and 240 mg/kg/day in young rats, with unequivocally toxic levels of 240 mg/kg/day and 720 mg/kg/day, respectively. Based on these two endpoints, the susceptibility of newborn rats to the chemical was approx. 3 times higher than that of young rats, consistent with our previous results for 4-nitrophenol and 2,4-dinitrophenol.

Young adult outcomes of very-low-birth-weight children.

PubMed

Hack, Maureen

2006-04-01

Information on the young adult outcomes of the initial survivors of neonatal intensive care has been reported from the United States, Canada, Australia, Great Britain and other European countries. The studies have varied with regard to whether they were regional or hospital-based, their birth-weight group and gestational age, rates of survival, socio-demographic background, and measures of assessment and types of outcome studied. Despite these differences the overall results reveal that neurodevelopment and growth sequelae persist to young adulthood. Very-low-birth-weight young adults have, with few exceptions, poorer educational achievement than normal-birth-weight controls, and fewer continue with post-high-school study. Rates of employment are, however, similar. There are no major differences in general health status, but the young adults demonstrate poorer physical abilities, higher mean blood pressure and poorer respiratory function. There is no evidence of major psychiatric disorder, although anxiety and depression are reported more often. The young adults report less risk-taking than control populations. They report fairly normal social lives and quality of life. When differences are noted they are usually due to neurosensory disabilities. Longer-term studies are needed to evaluate ultimate educational and occupational achievement. It will also be important to assess the effects of preterm birth, early growth failure and catch-up growth on later metabolic and cardiovascular health.

Healthy older adults have insufficient hip range of motion and plantar flexor strength to walk like healthy young adults.

PubMed

Anderson, Dennis E; Madigan, Michael L

2014-03-21

Limited plantar flexor strength and hip extension range of motion (ROM) in older adults are believed to underlie common age-related differences in gait. However, no studies of age-related differences in gait have quantified the percentage of strength and ROM used during gait. We examined peak hip angles, hip torques and plantar flexor torques, and corresponding estimates of functional capacity utilized (FCU), which we define as the percentage of available strength or joint ROM used, in 10 young and 10 older healthy adults walking under self-selected and controlled (slow and fast) conditions. Older adults walked with about 30% smaller hip extension angle, 28% larger hip flexion angle, 34% more hip extensor torque in the slow condition, and 12% less plantar flexor torque in the fast condition than young adults. Older adults had higher FCU than young adults for hip flexion angle (47% vs. 34%) and hip extensor torque (48% vs. 27%). FCUs for plantar flexor torque (both age groups) and hip extension angle (older adults in all conditions; young adults in self-selected gait) were not significantly <100%, and were higher than for other measures examined. Older adults lacked sufficient hip extension ROM to walk with a hip extension angle as large as that of young adults. Similarly, in the fast gait condition older adults lacked the strength to match the plantar flexor torque produced by young adults. This supports the hypothesis that hip extension ROM and plantar flexor strength are limiting factors in gait and contribute to age-related differences in gait. Copyright © 2014 Elsevier Ltd.

Meat protein in the diet has been shown to be beneficial for the growth of Lactobacillus in the caecum of growing rats; however, it is unknown whether gut microbiota in middle-aged animals have the same responses to meat protein diets. This study compared the composition of the gut microbiota between young and middle-aged rats after being fed 17.7% chicken protein diet for 14 days. Feces were collected on day 0 and day 14 from young rats (4 weeks old) and middle-aged rats (64 weeks old) fed with 17.7% chicken protein diets. The composition of the gut bacteria was analyzed by sequencing the V4-V5 region of the 16S ribosomal RNA gene. The results showed that the composition of the gut microbiota was significantly different between young and middle-aged rats on both day 0 and day 14. The percentage of Firmicutes decreased for middle-aged rats (72.1% versus 58.1% for day 0 and day 14, respectively) but increased for young rats (41.5 versus 57.7% for day 0 and day 14, respectively). The percentage of Bacteroidetes increased to 31.2% (20.5% on day 0) for middle-aged rats and decreased to 29.6% (41.3% on day 0) for young rats. The relative abundance of the beneficial genus Lactobacillus increased in response to the intake of chicken protein in the young group, while it had the opposite effect in the middle-aged group. The results of our study demonstrated that 17.7% chicken protein diet promoted the beneficial genus Lactobacillus in young rats, but the opposite effect were found in the middle-aged group. To evaluate the linkage between diet and host health, age effect should be considered in the future studies.

Prediction and evaluation of route dependent dosimetry of BPA in rats at different life stages using a physiologically based pharmacokinetic model

DOE Office of Scientific and Technical Information (OSTI.GOV)

Yang, Xiaoxia, E-mail: Xiaoxia.Yang@fda.hhs.gov; Doerge, Daniel R.; Fisher, Jeffrey W.

Bisphenol A (BPA) has received considerable attention throughout the last decade due to its widespread use in consumer products. For the first time a physiologically based pharmacokinetic (PBPK) model was developed in neonatal and adult rats to quantitatively evaluate age-dependent pharmacokinetics of BPA and its phase II metabolites. The PBPK model was calibrated in adult rats using studies on BPA metabolism and excretion in the liver and gastrointestinal tract, and pharmacokinetic data with BPA in adult rats. For immature rats the hepatic and gastrointestinal metabolism of BPA was inferred from studies on the maturation of phase II enzymes coupled withmore » serum time course data in pups. The calibrated model predicted the measured serum concentrations of BPA and BPA conjugates after administration of 100 μg/kg of d6-BPA in adult rats (oral gavage and intravenous administration) and postnatal days 3, 10, and 21 pups (oral gavage). The observed age-dependent BPA serum concentrations were partially attributed to the immature metabolic capacity of pups. A comparison of the dosimetry of BPA across immature rats and monkeys suggests that dose adjustments would be necessary to extrapolate toxicity studies from neonatal rats to infant humans. - Highlights: • A PBPK model predicts the kinetics of bisphenol A (BPA) in young and adult rats. • BPA metabolism within enterocytes is required for fitting of oral BPA kinetic data. • BPA dosimetry in young rats is different than adult rats and young monkeys.« less

Reaching young adult smokers through the internet: comparison of three recruitment mechanisms.

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

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

A successful captive breeding program for highly endangered black-footed ferrets (Mustela nigripes) has resulted in surplus animals that have been released at multiple sites since 1991. Because reproductive output of captive ferrets declines after several years, many adult ferrets must be removed from captive breeding facilities annually to keep total production high. Adults are routinely released, with young-of-the-year, on prairie dog (Cynomys spp.) colonies. We evaluated postrelease movements and survival rates for 94 radio-tagged young and adult ferrets. Radio-tagged adult ferrets made longer movements than young ferrets during the night of release and had significantly lower survival rates for the first 14 days. Coyotes (Canis latrans) caused the largest number of ferret losses. A larger data set of 623 ferrets represented adults and young that were individually marked with passive integrated transponders but were not radio tagged. Minimum survival rates, calculated primarily from ferrets detected during spotlight searches and identified with tag readers, again were significantly lower for adults than for young ferrets at 30 days postrelease (10.1 percent and 45.5 percent survival, respectively) and at 150 days postrelease (5.7 percent and 25.9 percent). Assessment of known survival time by using linear modeling demonstrated a significant interaction between age and sex, with greater disparity between adults and kits for females than for males. Postrelease survival of adult ferrets might be increased if animals were given earlier and longer exposure to the quasinatural environments of preconditioning pens.

2010-01-01

This paper is a report of a study exploring the meaning of interactions with and supports of self-management from parents and other significant others for young adults with type 1 diabetes. Adolescence and young adulthood is known to be a critical period for people living with diabetes in terms of diabetes control, which is why support from significant others is of utmost importance during the transition to adult life. A grounded theory approach was used. Interviews with 13 young adults with type 1 diabetes and 13 parents 2 years after transfer to adult diabetes care were conducted during 2006-2007. Internet communication between young people on a diabetes website was also included in the constant comparative analysis. Transition to adult life for young adults with diabetes was characterized by a relational and reflexive process leading to ongoing redefinition of relationships and identity. Parents were perceived as the most reliable supporters, compared to partners, siblings and other significant others. Chat friends can also become important through emotional, social and diabetes-related support in internet communication. The young adults showed growing awareness of their own capacities, shortcomings and emotional reactions, reflections which contribute to a redefinition of self. Further research is needed to explore how contemporary interactions contribute to development of the self. By focusing on supporting relationships, nurses are in a strategic position to develop knowledge and modify clinical programmes that promote diabetes management and care by taking supporting interactions into account from a contemporary point of view.

Black-White Disparity in Young Adults' Disease Risk: An Investigation of Variation in the Vulnerability of Black Young Adults to Early and Later Adversity.

Socioeconomic adversity in early years and young adulthood are risk factors for poor health in young adulthood. Population differences in exposure to stressful socioeconomic conditions partly explain the higher prevalence of disease among black young adults. Another plausible mechanism is that blacks are differentially vulnerable to socioeconomic adversity (differential vulnerability hypothesis), which has not been adequately investigated in previous research. The present study investigated variation in the vulnerability of black young adults leading to cardiometabolic (CM) disease risk. We used a nationally representative sample of 8,824 adolescents who participated in the Add Health study. Early and later adversity was measured using a cumulative index of social and material adversity in adolescence and young adulthood. CM disease risk was assessed using nine biomarkers. Path analysis within a structural equation modeling framework was used. The findings indicated that both early and later socioeconomic adversity act as stressors with independent additive influences on young adults' CM disease risk, consistent with the differential exposure hypothesis. Moreover, the results showed that black youth are less vulnerable to early socioeconomic adversity than whites, but they are more vulnerable to later adversity. The findings provide support for the unique and additive influences of early and later socioeconomic adversity on CM disease risk contributing to the black-white health disparity in young adulthood. The results also suggest that vulnerability to adversity varies depending on the life stage, which highlights the need for life-stage specific interventions to mitigate the existing black-white disparity in young adults' physical health.

Framing disability among young adults with disabilities and non-disabled young adults: an exploratory study.

PubMed

Soffer, Michal; Chew, Fiona

2015-01-01

To explore how young adults frame disability and to compare the meanings of disability between persons with and without disabilities. Snow ball sampling was used to recruit the participants. The sample comprised of 14 young adults from Upstate New York area; nine were non-disabled, five had a physical disability. Data were collected by semi-structured interviews. Qualitative content analysis was used to analyze the data. Five themes emerged from the analysis: disability as a deviation from "the norm", disability as inability, disability as something one needs to overcome, the role of the environment in disability, and disability as a negative phenomenon. The findings suggest that persons with disabilities hold somewhat different meanings of disability compared with non-disabled persons. While the biomedical frame of disability was somewhat challenged, disability is mainly understood via a biomedical lens. Disability should be framed as form of human diversity, not as a mark of Cain.

[Relationship between the growth rate of the liver of young rats and the inhibitory effect of extracts of their liver on the multiplication of cultured cells].

PubMed

Aujard, C; Chany, E; Frayssinet, C

1976-12-08

We have shown that extracts of liver from young Rats are less active, than extracts of liver from adult Rats, in inhibiting the multiplication of cells in culture. This inhibitory activity is at a minimum in livers taken from 10 to 15 days old Rats, which corresponds to the time of maximum increase in weight of the liver. The existence of an inverse relationship between the inhibitory activity of these extracts and the state of proliferation of the liver suggests that the inhibitory substance contained in the liver extracts may act as a regulator of growth of the organ.

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

Young and old rats, aged 3 and 24 months old, respectively, were conditioned to press a lever under lamp-on conditions for reward acquisition and lamp-off for no reward using a variable interval reinforcement schedule that averaged 15 s; i.e., the minimal requirement was 4 responses/min. Over a 30-day period, young and old groups showed increased response to lamp-on from 22 to 35/min and from 10 to 23/min, respectively, and shortened response to lamp-off after initial training. Response to lamp-on as a percentage of total response to lamp-on and -off (the discrimination ratio) was over 80%. For the next 30 days, reversal learning was imposed to reinforce discrimination of the lamp-off state. Young rats showed a steadily increasing discrimination ratio from 40% to 70%, and old rats from 30% to 60%. In comparison with the initial training, young rats showed a total response increase from 50% to 60%, while old rats showed an approximately 5% decrease without loss of reward-obtaining efficiency. In vivo microdialysis during reversal revealed that young rats had higher dopamine transmission in the basolateral amygdala than old rats. The dopamine level was positively correlated with the number of responses to state of reward in young rats and negatively with the numbers of both NRF and RF responses to lamp-on and -off states in old rats. These results suggest that in reversal discrimination, basolateral amygdalar dopamine efflux correlates with the manner of age-related conditioned response rather than the ability to learn.

Background: A growing body of evidence indicates that the density of tobacco retail outlets around the home residence may influence tobacco use among youth and adults. The purpose of this study was to examine the impact of neighborhood tobacco retail outlet density on young adult initiation of different tobacco product types. Methods: Cross-sectional data from a 2013 nationally representative sample of young adults aged 18–34 was examined in relation to a 2012 geocoded listing of all outlets likely to sell tobacco in the United States. Separate multivariable logistic regression analyses examined associations between neighborhood outlet density and past 6 months first use of cigarettes, non-cigarette combustible products, and noncombustible products among adults aged 18–24 and 25–34. Results: Outlet density was significantly associated with recent initiation of cigarettes and other combustibles, but this impact varied for younger and older groups. Increased density was significantly associated with a higher likelihood of initiating cigarette use among adults aged 25–34 (OR = 3.75, 95% CI = 1.18, 11.90), and of initiating non-cigarette combustible use among 18–24 year olds (OR = 3.16, 95% CI = 1.03, 9.74). There was no impact of outlet density on recent noncombustible product initiation among either group. Conclusion: This study is the first to examine the impact of tobacco outlet density on young adult initiation of cigarettes and other tobacco products. Findings demonstrate that residential neighborhood outlet density is associated with recent initiation of combustible products and this effect varies by product type and age. The tobacco outlet environment may be a critical factor in promoting young adult tobacco use initiation. PMID:25666816

Objective To determine the impact of hormones on the biomechanical properties of the vagina and its supportive tissues following surgical menopause in young vs middle aged rats. Methods Long-Evans rats [4-month virgin (N = 34), 4-month parous (N = 36), and 9-month parous (N = 34)], underwent ovariectomy (OVX) or sham surgery. OVX'd animals received hormones [estrogen (E2) or estrogen plus progesterone (E2 + P4)], placebo, or the Matrix Metalloproteinase inhibitor (CMT-8). Animals were sacrificed after 8 weeks and the biomechanical properties of the vagina and supportive tissues determined. Data was analyzed using a one-way analysis of variance and post-hoc tests. Results OVX induced a rapid decline in the biomechanical properties of pelvic tissues in young but not middle aged rats. Supplementation with E2, E2 + P4, or CMT-8 restored tissues of young rats to control levels with no effect on middle aged tissues. Parity did not impact tissue behavior. Conclusions OVX has a differential effect on the tissues of young vs middle aged rats. PMID:18395691

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

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

2016-03-01

We explored beliefs about electronic cigarettes (e-cigarettes) as well as social influences on e-cigarette use in straight-to-work (STW) young adults. Thirty interviews were conducted with STW young adults ages 19-31 years old. We asked participants about smoking and e-cigarette use, beliefs about e-cigarettes, and influences on decisions to use e-cigarettes. We conducted interviews in community locations and transcribed and coded them using NVivo. We identified 4 themes: benefits of e-cigarette use; dual use/continued smoking; social influences; and quitting smoking and e-cigarettes. STW young adults initiated e-cigarette use to quit smoking but most became dual users or reported cycles of smoking and e-cigarette use. Flavors were a primary attraction for e-cigarette users. Family and friends supported e-cigarette use and often provided participants with their first e-cigarette. Most participants who no longer identified as smokers still smoked occasionally. Users felt they were more positively perceived by others when they used e-cigarettes but were still seen as smokers or former smokers. E-cigarette use may bring STW young adults closer to their aspirational identity of non-smoker but many may be vulnerable to smoking relapse or increased dependence on nicotine through dual use.

1999-04-01

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

Previous research has established that treatments for cancer can result in short- and long-term effects on sexual function in adult cancer patients. The purpose was to investigate patient-reported physical and psychosexual complications in adolescents and young adults after they have undergone treatment for cancer. In this population-based study, a study-specific questionnaire was developed by a method used in several previous investigations carried out by our research group, Clinical Cancer Epidemiology. The questionnaire was developed in collaboration with adolescent and young adult cancer survivors (15-29 years) and validated by professionals from oncology units, midwives, epidemiologists, and statisticians. The topics covered in the questionnaire were psychosocial health, body image, sexuality, fertility, education, work, and leisure. The web-based questionnaire was sent to adolescent and young adult cancer survivors and matched controls in Sweden. In this study, adolescent and young adult cancer survivors (15-29 years) showed low satisfaction regarding sexual function compared to controls (P < 0.01). Female adolescent and young adult cancer survivors had a statistically significant lower frequency of orgasm during sexual activity than the controls (P < 0.01). Male adolescent and young adult cancer survivors had statistically significant lower sexual desire than the controls (P = 0.04). We found that adolescent and young adult cancer survivors perceived themselves as being less satisfied with their sexual function than matched population-based controls. Adolescent and young adult cancer survivors need psychological rehabilitation support from the health care profession during and after cancer treatment to help them to reduce their reported poor sexual function to enhance a good sexual quality of life.

The individual placement and support (IPS) model of supported employment was first developed in community mental health centres for adults with severe mental illness. While IPS is an established evidence-based practice in this broad population, evidence on its effectiveness focused specifically on young adults has been limited. The current study aimed to address this gap. To investigate the effects of IPS on young adults, the authors conducted a secondary analysis on a pooled sample of 109 unemployed young adults (under age 30) from four randomized controlled trials employing a common research protocol that included a standardized measurement battery and rigorous fidelity monitoring. Researchers assessed these participants over 18 months on nine competitive employment outcome measures. On all measures, the IPS group had significantly better employment outcomes. Overall, 40 (82%) of IPS participants obtained employment during follow-up compared with 25 (42%) of control participants, χ(2) = 17.9, P < .001. IPS participants averaged 25.0 weeks of employment, compared with 7.0 weeks for control participants, t = 4.50, P < .001. The current analysis supports a small number of previous studies in showing that IPS is highly effective in helping young adults with severe mental illness to attain competitive employment. When young adults acquire competitive jobs and initiate a path towards normal adult roles, they may avoid the cycle of disability and psychiatric patient roles that are demeaning and demoralizing. © 2014 Wiley Publishing Asia Pty Ltd.

Objective The Individual Placement and Support (IPS) model of supported employment was first developed in community mental health centers for adults with severe mental illness. While IPS is an established evidence-based practice in this broad population, evidence on its effectiveness focused specifically on young adults has been limited. The current study aimed to address this gap. Methods To investigate the effects of IPS on young adults, the authors conducted a secondary analysis on a pooled sample of 109 unemployed young adults (under age 30) from four randomized controlled trials employing a common research protocol that included a standardized measurement battery and rigorous fidelity monitoring. Researchers assessed these participants over 18 months on nine competitive employment outcome measures. Results On all measures the IPS group had significantly better employment outcomes. Overall, 40 (82%) of IPS participants obtained employment during follow-up compared to 25 (42%) of control participants, Χ2 =17.9, p < .001. IPS participants averaged 25.0 weeks of employment, compared to 7.0 weeks for control participants, t = 4.50, p < .001. Conclusions The current analysis supports a small number of previous studies in showing that IPS is highly effective in helping young adults to attain competitive employment. When young adults acquire competitive jobs and initiate a path toward normal adult roles, they may avoid the cycle of disability and psychiatric patient roles that are demeaning and demoralizing.

This study used data from the Pittsburgh ADHD Longitudinal Study (PALS) to evaluate financial outcomes of young adults (YA) with ADHD relative to comparisons. Participants for this study included 309 individuals who had been diagnosed with ADHD (DSM-III-R or DSM-IV) in childhood and 208 comparison YA without childhood ADHD diagnoses (total N = 517) who were followed through age 25. Participants were predominately male (88 %) and Caucasian (84 %). Diagnostic interviews were conducted in childhood. Young adults and their parents reported on financial outcomes and a number of predictor variables. Young adults with ADHD experienced greater financial dependence on family members (p < 0.05) and the welfare system (p < 0.01) and had lower earnings (p < 0.05) than comparisons. ADHD diagnostic status, education attainment, and delinquency were significant predictors of financial outcomes. A projection of lifetime earnings indicated that ADHD group participants could expect to earn $543,000-$616,000 less over their lifetimes than comparisons. Due to the propensity of individuals with ADHD to underreport problems, the data are likely to be underestimates. These findings support the need for interventions to improve labor market outcomes as well as the development of interventions that target the management of personal finances for individuals with ADHD in young adulthood.

2014-02-01

Our understanding of age-related changes to foot function during walking has mainly been based on plantar pressure measurements, with little information on differences in foot kinematics between young and older adults. The purpose of this study was to investigate the differences in foot kinematics between young and older adults during walking using a multi-segment foot model. Joint kinematics of the foot and ankle for 20 young (mean age 23.2 years, standard deviation (SD) 3.0) and 20 older adults (mean age 73.2 years, SD 5.1) were quantified during walking with a 12 camera Vicon motion analysis system using a five segment kinematic model. Differences in kinematics were compared between older adults and young adults (preferred and slow walking speeds) using Student's t-tests or if indicated, Mann-Whitney U tests. Effect sizes (Cohen's d) for the differences were also computed. The older adults had a less plantarflexed calcaneus at toe-off (-9.6° vs. -16.1°, d = 1.0, p = <0.001), a smaller sagittal plane range of motion (ROM) of the midfoot (11.9° vs. 14.8°, d = 1.3, p = <0.001) and smaller coronal plane ROM of the metatarsus (3.2° vs. 4.3°, d = 1.1, p = 0.006) compared to the young adults. Walking speed did not influence these differences, as they remained present when groups walked at comparable speeds. The findings of this study indicate that independent of walking speed, older adults exhibit significant differences in foot kinematics compared to younger adults, characterised by less propulsion and reduced mobility of multiple foot segments.

Young adults at work without basic educational level (BEL), and young adults in Neither Employment, Education nor Training (NEET) are at high risk of adverse employment outcomes. Evidence lacks on the impact of mental health problems during childhood, adolescence and young adulthood on employment outcomes of young adults. Therefore, the aims of this study were to (1) identify trajectories of mental health problems from childhood to young adulthood and (2) investigate the relation between these trajectories and the educational or employment status of young adults. Data were used from the Tracking Adolescents' Individual Lives Survey (TRAILS), a Dutch prospective cohort study with 9-year follow-up. Trajectories of mental health problems measured at ages 11, 13.5, 16 and 19 years were identified in 1711 young adults with latent class growth models. Young adults with high-stable trajectories of total problems, from childhood to young adulthood, were more likely to work without BEL or be in NEET at age 19, than to be at school or to work with BEL (28.0% vs 16.0%, p=0.01). The same was found for externalising problems (35.3% vs 23.2%, p=0.02). For internalising and attention problems, no statistically significant differences were found. Young adults with high-stable trajectories of mental health problems from age 11 to 19, were at risk of adverse employment outcomes. Interventions reducing mental health problems in childhood may improve the educational or employment status of young adults and their chances for successfully entering the labour market.

Reactivity to Exclusion Prospectively Predicts Social Anxiety Symptoms in Young Adults

2013-01-01

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

Deaths from stroke in US young adults, 1989–2009

Objective: To determine what the trends in stroke mortality have been over 2 decades in young adults. Methods: In this cohort study, we analyzed death certificate data for ischemic and hemorrhagic stroke (intracerebral hemorrhage [ICH] and subarachnoid hemorrhage [SAH]) in adults aged 20–44 in the United States for 1989 through 2009, covering approximately 2.2 billion person-years. Poisson regression was used to calculate and compare time trend data between groups and to compare trends in young adults to those in adults over age 45. Results: Mortality from stroke in young adults declined by 35% over the study period, with reductions in all 3 stroke subtypes (ischemic stroke decreased by 15%, ICH by 47%, and SAH by 50%). Black race was a risk factor for all 3 stroke subtypes (relative risk 2.4 for ischemic stroke, 4.0 for ICH, and 2.1 for SAH), but declines in all stroke subtypes were more dramatic in black compared to white participants (p < 0.001 for all stroke subtypes). Conclusions: Although hospitalizations for stroke in young patients have been increasing, the apparent decrease in mortality rates and in racial disparities suggests that recognition and treatment in this group may be improving.

Bombesin-induced changes in expression of pancreatic enzymes in young and old rats.

PubMed

Dubick, M A; Cornell, T; Majumdar, A P

1993-01-01

Bombesin is known to induce pancreatic growth. In aged animals, reduced responsiveness of tissues of the gastrointestinal tract to a number of hormones/peptides, including bombesin, has been demonstrated, yet the effects of chronic bombesin administration on the aging pancreas is poorly understood. In the present study, groups of 4- and 20- to 22-month-old male Fischer 344 rats were infused by osmotic minipump with saline (control) or bombesin (300 ng/kg/h) for 14 days. In young rats, bombesin administration increased trypsin activity in the pancreas, which was accompanied by an increase in trypsinogen steady-state mRNA levels. However, this response to bombesin was not observed in aged rats. Bombesin also increased pancreatic glutathione peroxidase and reductase, but not superoxide dismutase activity in young rats, whereas activity of these antioxidant enzymes was not affected by bombesin in old rats. These data further support the observation that responsiveness of the pancreas to hormones is diminished with advancing age.

Goals and everyday problem solving: manipulating goal preferences in young and older adults.

PubMed

Hoppmann, Christiane A; Blanchard-Fields, Fredda

2010-11-01

In the present study, we examined the link between goal and problem-solving strategy preferences in 130 young and older adults using hypothetical family problem vignettes. At baseline, young adults preferred autonomy goals, whereas older adults preferred generative goals. Imagining an expanded future time perspective led older adults to show preferences for autonomy goals similar to those observed in young adults but did not eliminate age differences in generative goals. Autonomy goals were associated with more self-focused instrumental problem solving, whereas generative goals were related to more other-focused instrumental problem solving in the no-instruction and instruction conditions. Older adults were better at matching their strategies to their goals than young adults were. This suggests that older adults may become better at selecting their strategies in accordance with their goals. Our findings speak to a contextual approach to everyday problem solving by showing that goals are associated with the selection of problem-solving strategies.

Development of acute hydrocephalus does not change brain tissue mechanical properties in adult rats, but in juvenile rats.

Regional changes in brain stiffness were previously demonstrated in an experimental obstructive hydrocephalus juvenile rat model. The open cranial sutures in the juvenile rats have influenced brain compression and mechanical properties during hydrocephalus development and the extent by which closed cranial sutures in adult hydrocephalic rat models affect brain stiffness in-vivo remains unclear. The aims of this study were to determine changes in brain tissue mechanical properties and brain structure size during hydrocephalus development in adult rat with fixed cranial volume and how these changes were related to brain tissue deformation. Hydrocephalus was induced in 9 female ten weeks old Sprague-Dawley rats by injecting 60 μL of a kaolin suspension (25%) into the cisterna magna under anaesthesia. 6 sham-injected age-matched female SD rats were used as controls. MR imaging (9.4T, Bruker) was performed 1 day before and then at 3 days post injection. T2-weighted anatomical MR images were collected to quantify ventricle and brain tissue cross-sectional areas. MR elastography (800 Hz) was used to measure the brain stiffness (G*, shear modulus). Brain tissue in the adult hydrocephalic rats was more compressed than the juvenile hydrocephalic rats because the skulls of the adult hydrocephalic rats were unable to expand like the juvenile rats. In the adult hydrocephalic rats, the cortical gray matter thickness and the caudate-putamen cross-sectional area decreased (Spearman, P < 0.001 for both) but there were no significant changes in cranial cross-sectional area (Spearman, P = 0.35), cortical gray matter stiffness (Spearman, P = 0.24) and caudate-putamen (Spearman, P = 0.11) stiffness. No significant changes in the size of brain structures were observed in the controls. This study showed that although brain tissue in the adult hydrocephalic rats was severely compressed, their brain tissue stiffness did not change significantly. These results are in contrast with our

Purpose Examine young adults' health care utilization and expenditures prior to the ACA. Methods We used 2009 Medical Expenditure Panel Survey (MEPS) to 1) compare young adults' health care utilization and expenditures of a full-spectrum of health services to children and adolescents and 2) identify disparities in young adults' utilization and expenditures, based on access (insurance and usual source of care) and other socio-demographic factors, including race/ethnicity and income. Results Young adults had: 1) significantly lower rates of overall utilization (72%) than other age groups (83-88%, P<.001) and 2), the lowest rate of office-based utilization (55% vs. 67-77%, P<.001) and higher rate of ER visits compared to adolescents (15% v. 12%, P<.01). Uninsured young adults had high out-of-pocket expenses. Compared to the young adults with private insurance, the uninsured spent less than half on health care ($1,040 vs. $2,150/ person, P<.001), but essentially the same out-of-pocket expenses ($403 vs. $380/person, p =.57). Among young adults, we identified significant disparities in utilization and expenditures based on the presence/absence of a usual source of care, race/ethnicity, home language and sex. Conclusions Young adults may not be utilizing the health care system optimally by having low rates of office-based visits and high rates of ER visits. The ACA provision of insurance for those previously uninsured or under-insured will likely increase their utilization and expenditures and lower their out-of-pocket expenses. Further effort is needed to address non-insurance barriers and ensure equal access to health services. PMID:24702839

Objective To examine self-reported rates and disparities in delivery of preventive services to young adults. Design Population-based cross-sectional analysis. Multivariate logistic regression was used to examine how age, gender, race/ethnicity, income, insurance, and usual source of care influence the receipt of preventive services. Setting 2005 and 2007 California Health Interview Surveys (CHIS). Participants 3670 and 3621 young adults aged 18-26 years who responded to CHIS 2005 and 2007, respectively. Main Outcome Measures Self-reported receipt of flu vaccination, STD screening, cholesterol screening, diet counseling, exercise counseling and emotional health screening. Results Delivery rates ranged from 16.7% (flu vaccine) to 50.6% (cholesterol screening). Being female and having a usual source of care significantly increased receipt of services, with females more likely to receive STD screening (p<.001), cholesterol screening (p<.01), emotional health screening (p<.001), diet counseling (p<.01) and exercise counseling (p<.05) than males after controlling for age, race/ethnicity, income, insurance and usual source of care. Young adults with a usual source of care were more likely to receive a flu vaccine (p<.05), STD screening (p<.01), cholesterol screening (p<.001), diet counseling (p<.05) and exercise counseling (p<.05) than those without a usual source of care after adjusting for age, race/ethnicity, income, and insurance. Conclusions Rates of preventive service delivery are generally low. Greater efforts are needed to develop guidelines for young adults to increase the delivery of preventive care to this age group, and to address the gender and ethnic/racial disparities in preventive services delivery.

OBJECTIVE Young adults with type 1 diabetes transitioning from pediatric to adult care are at risk for adverse outcomes. Our objective was to describe experiences, resources, and barriers reported by a national sample of adult endocrinologists receiving and caring for young adults with type 1 diabetes. RESEARCH DESIGN AND METHODS We fielded an electronic survey to adult endocrinologists with a valid e-mail address identified through the American Medical Association Physician Masterfile. RESULTS We received responses from 536 of 4,214 endocrinologists (response rate 13%); 418 surveys met the eligibility criteria. Respondents (57% male, 79% Caucasian) represented 47 states; 64% had been practicing >10 years and 42% worked at an academic center. Only 36% of respondents reported often/always reviewing pediatric records and 11% reported receiving summaries for transitioning young adults with type 1 diabetes, although >70% felt that these activities were important for patient care. While most respondents reported easy access to diabetes educators (94%) and dietitians (95%), fewer (42%) reported access to mental health professionals, especially in nonacademic settings. Controlling for practice setting and experience, endocrinologists without easy access to mental health professionals were more likely to report barriers to diabetes management for young adults with depression (odds ratio [OR] 5.3; 95% CI 3.4, 8.2), substance abuse (OR 3.5; 95% CI 2.2, 5.6), and eating disorders (OR 2.5; 95% CI 1.6, 3.8). CONCLUSIONS Our findings underscore the need for enhanced information transfer between pediatric and adult providers and increased mental health referral access for young adults with diabetes post-transition.

To compare long-term outcome of children and young adults with arterial ischemic stroke (AIS) from 2 large registries. Prospective cohort study comparing functional and psychosocial long-term outcome (≥2 years after AIS) in patients who had AIS during childhood (1 month-16 years) or young adulthood (16.1-45 years) between January 2000 and December 2008, who consented to follow-up. Data of children were collected prospectively in the Swiss Neuropediatric Stroke Registry, young adults in the Bernese stroke database. Follow-up information was available in 95/116 children and 154/187 young adults. Median follow-up of survivors was 6.9 years (interquartile range 4.7-9.4) and did not differ between the groups (p = 0.122). Long-term functional outcome was similar (p = 0.896): 53 (56%) children and 84 (55%) young adults had a favorable outcome (modified Rankin Scale 0-1). Mortality in children was 14% (13/95) and in young adults 7% (11/154) (p = 0.121) and recurrence rate did not differ (p = 0.759). Overall psychosocial impairment and quality of life did not differ, except for more behavioral problems among children (13% vs 5%, p = 0.040) and more frequent reports of an impact of AIS on everyday life among adults (27% vs 64%, p < 0.001). In a multivariate regression analysis, low Pediatric NIH Stroke Scale/NIH Stroke Scale score was the most important predictor of favorable outcome (p < 0.001). There were no major differences in long-term outcome after AIS in children and young adults for mortality, disability, quality of life, psychological, or social variables. © 2015 American Academy of Neurology.

Repetition blindness and homophone blindness in young and older adults.

PubMed

Tyrrell, Caitlin J; James, Lori E; Noble, Paula M

2016-11-01

We tested age effects on repetition blindness (RB), defined as the reduced probability of reporting a target word following presentation of the same word in a rapidly presented list. We also tested age effects on homophone blindness (HB), in which the first word is a homophone of the target word rather than a repeated word. Thirty young and 28 older adults viewed rapidly presented lists of words containing repeated, homophone, or unrepeated word pairs and reported all of the words immediately after each list. Older adults exhibited a greater degree of RB and HB than young adults using a conditional scoring method that provides certainty that blindness has occurred. The existence of RB and HB for both age groups, and increased blindness for older compared to young adults, supports predictions of a binding theory that has successfully accounted for a wide range of phenomena in cognitive aging.

2009-01-01

Objectives. We examined relationships between parenting status and multiple forms of violence perpetration among young adults in high-poverty environments. Methods. We analyzed data obtained from a survey of 990 young adults in New York City. Respondents reported on violence they had perpetrated toward themselves, intimate partners, and others. Associations between parenting and violence were examined in logistic regressions, controlling for sociodemographics. Results. Fewer young men (33.0%) than young women (48.6%) reported that they were raising children. Among young men, parenting was associated with violence toward themselves (odds ratio [OR] = 1.8; 95% confidence interval [CI] = 1.03, 3.16) but not with violence toward partners or others. Among young women, violence perpetration did not differ by parenting status. Correlations among forms of violence were higher among young women than among young men, especially among mothers. Community violence was associated with violence toward others for both genders. For young men, community violence was associated with violence toward partners. Conclusions. Parenting did not reduce inner-city young adults' perpetration of violence. Among fathers, parenting may be, along with unemployment, a risk for violence toward self. Understanding patterns of violence can inform interventions that support young adults, including those who are parenting, in creating nonviolent homes and communities. PMID:19833989

Knowledge and Beliefs About E-Cigarettes in Straight-to-Work Young Adults.

2017-02-01

Young adults are a growing segment of electronic cigarette (e-cigarette) users. Young adults who go straight to work (STW) from high school make up a large portion of the young adult population, yet research to date has focused on college-educated young adults. This study explored STW young adult beliefs and knowledge about e-cigarettes. Semistructured individual interviews were used to elicit in-depth information from STW young adults ages 19-31 from a state in the southwest United States. Thirty interviews were conducted focusing on beliefs about e-cigarettes, current knowledge, and information-seeking practices. Interviews were recorded, transcribed, and analyzed using NVivo. Nine themes were identified falling into three categories: (1) beliefs about e-cigarettes, (2) knowledge about e-cigarettes, and (3) personal rules about e-cigarettes. STW young adults held positive beliefs about the health and safety of e-cigarettes for themselves, others, and the environment. They reported their social networks and the Internet as reliable sources of information about e-cigarettes, but they reported parents as the best source for advice. Participants had rules about e-cigarettes that contradicted some of their beliefs such as using e-cigarettes around children indicating that their beliefs were not as strongly held as they initially reported. Industry marketing and contradictory information may contribute to STW young adult knowledge and beliefs about e-cigarettes. Lack of credible public health information may also contribute to this issue. Ensuring that what is known about the benefits and harms of e-cigarettes is conveyed through multichannel communication and continued monitoring of marketing practices of the e-cigarette industry in light of the soon to be implemented regulations should be top priorities for public health. Beliefs and knowledge of STW young adults have not been explored even though they are heavily targeted by the e-cigarette industry. This group

Functional Gastrointestinal disorders (FGID) are common disorders in gastroenterology which are common in young adults. The aim of this study is evaluating the prevalence of upper FGID in iranian young adults. This was a cross-sectional study which was on 995 persons who were going to marry. A ROME III based questionnaire was used to determine the frequency of upper GI Syndromes among the sample population. Our results determined 74 subjects had functional dyspepsia (36 subjects diagnosed as postprandial distress syndrome patient and Epigastric pain syndrome was seen in 38 subjects). Functional heartburn was diagnosed in 52 participants. Globus was seen in 35 subjects and 41 had unspecified excessive belching. Many epidemiologic studies were done all around the world but there are different reports about prevalence and incidence of FGIDs. Our results were agreed with reported prevalence of FGIDs in Iran in adults. And our findings were agreed with some other Asian studies.

Motor vehicle crashes are the leading cause of death among young drivers. Though previous research has focused on crash events, near crashes offer additional data to help identify driver errors that could potentially lead to crashes as well as evasive maneuvers used to avoid them. The Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study (NDS) contains extensive data on real-world driving and offers a reliable methodology to quantify and study near crashes. This article presents findings on near crashes and how they compare to crash events among teen, young adult, and experienced adult drivers. A subset from the SHRP2 database consisting of 1,653 near crashes for teen (16-19 years, n = 550), young adult (20-24 years, n = 748), and experienced adult (35-54 years, n = 591) drivers was used. Onboard instrumentation including scene cameras, accelerometers, and Global Positioning System logged time series data at 10 Hz. Scene videos were reviewed for all events to classify near crashes based on 7 types: rear-end, road departure, intersection, head-on, side-swipe, pedestrian/cyclist, and animal. Near crash rates, incident type, secondary tasks, and evasive maneuvers were compared across age groups and between crashes and near crashes. For rear-end near crashes, vehicle dynamic variables including near crash severity, headway distance, time headway, and time to collision at the time of braking were compared across age groups. Crashes and near crashes were combined to compare the frequency of critical events across age. Teen drivers exhibited a significantly higher (P <.01) near crash rate than young adult and experienced adult drivers. The near crash rates were 81.6, 56.6, and 37.3 near crashes per million miles for teens, young adults, and experienced adults, respectively. Teens were also involved in significantly more rear-end (P <.01), road departure (P <.01), side-swipe (P <.01), and animal (P <.05) near crashes compared to young and experienced

Lymphoma is one of the most frequent cancers in adolescent and young adults. Hodgkin Lymphoma is curable in more than 90% of cases. Recent pediatric and adults protocols aimed to decrease long term toxicities (mostly gonadic and cardiovascular) and secondary malignancies, reducing the use of alkylating agents and limiting radiation fields. Risk-adapted strategies, using positron emission tomography staging, are about to become a standard, both in adult and pediatric protocols. These approaches allow obtaining excellent results in adolescents with Hodgkin lymphoma. On the other hand, treatment of adolescents with diffuse large B-cell lymphoma raises some questions. Even through children have good outcomes when treated with risk-adapted strategies, adolescents who are between 15 and 18 years old seem to experience poorer survivals, whereas patients older than 18 years old have globally the same outcome than older adults. This category of patient needs a particular care, based on a tight coordination between adults and pediatric oncologists. Primary mediastinal lymphomas, a subtype of BLDCL frequent in young adult population, exhibits poorer outcomes in children or young adolescent population than in older ones. Taking together, B-cell lymphoma benefited from recent advances in immunotherapy (in particular with the extended utilization of rituximab) and metabolic response-adapted strategies. In conclusion, adolescent and young adult's lymphomas are very curable diseases but require a personalized management in onco-hematological units. Copyright © 2016 Société Française du Cancer.

This study assessed whether smoking in the movies was associated with smoking in young adults. A national web-enabled cross-sectional survey of 1528 young adults, aged 18-25, was performed between September and November 2005. Logistic regression and path analysis using probit regression were used to assess relationships between exposure to smoking in the movies and smoking behavior. Analysis was completed in December 2006. Exposure to smoking in the movies predicted current smoking. The adjusted odds of current smoking increased by a factor of 1.21 for each quartile increase in exposure to smoking (p<0.01) in the movies, reaching 1.77 for the top exposure quartile. The unadjusted odds of established smoking (100+ cigarettes with current smoking) increased by 1.23 per quartile (p<0.001) of exposure, reaching 1.86 for the top quartile. This effect on established smoking was mediated by two factors related to smoking in the movies: positive expectations about smoking and exposure to friends and relatives who smoked, with positive expectations accounting for about two thirds of the effect. The association between smoking in the movies and young adult smoking behavior exhibited a dose-response relationship; the more a young adult was exposed to smoking in the movies, the more likely he or she would have smoked in the past 30 days or have become an established smoker.

Objective To explore the effects of subcutaneous microenvironment of adult rats on survival, development and androgen secretion of Leydig cells of transplanted juvenile rat testis. Methods Healthy adult SD rats were randomly divided into control group, sham group, castrated group and non-castrated group. Rats in the control group were kept intact, no testis was transplanted subcutaneously after adult recipients were castrated in the sham group; 5-7-day juvenile rat testes were transplanted subcutaneously in the castrated group, with one testis per side; Testes resected from juvenile rats were directly transplanted subcutaneously on both sides of the recipients in the non-castrated group. The grafts were obtained and weighed 4 weeks later. Then the histological features of the grafts were examined by HE staining; the expression and distribution of hydroxysteroid 17-beta dehydrogenase 1 (HSD-17β1) were investigated by immunohistochemistry; and the serum androgen level was determined by ELISA. Results The average mass of grafts obtained from the castrated group was significantly higher than that of the non-castrated group. Immunohistochemistry indicated that Leydig cells were visible in the tissues from both the castrated and non-castrated groups, but the number of HSD-17β1-posotive cells in the castrated group was larger than that in the non-castrated group. ELISA results showed that the serum androgen level was higher in the control group and non-castrated group than in the sham group and castrated group, and compared with the sham group, the serum androgen level in the castrated group was significantly higher. Conclusion The juvenile rat testis subcutaneously transplanted could further develop under the adult recipient rat skin, and the Leydig cells of grafts harbored the ability to produce and secret androgen.

The effects of nicergoline on basal and K(+)-stimulated release of ACh in the hippocampus of 3- and 19-month old rats has been studied by microdialysis. A significant decrease of basal ACh release (59%) was found in aged vehicle treated rats in comparison to young rats. High-K+ (100 mM) in the perfusate strongly increased the release of ACh by up to 6-fold over the baseline of both young and aged rats. Chronic oral administration of nicergoline to aged rats (5 mg/kg b.i.d. for 6 weeks) significantly reversed (93%) the age-related decrease of basal release of ACh, leaving the increase due to K+ depolarization unchanged. In young animals, nicergoline did not affect the basal output of ACh, but enhanced the K(+)-evoked release of ACh by 39%. Results from this study demonstrate that nicergoline treatment increases the ability of hippocampal cholinergic terminals to release ACh, and suggest that this drug can reset the cholinergic impairement associated with aging.

The objective of the present study was to determine the reliability and validity of the Persian translation of the Pediatric Quality of Life Inventory (PedsQL™) 4.0 Generic Core Scales Young Adult Version in an Iranian sample of young adult patients with rheumatoid arthritis (RA). One hundred ninety-seven young adult patients with RA completed the 23-item PedsQL™ and the 36-item Short-Form Health Survey (SF-36). Disease activity based on Disease Activity Score 28 was also measured. Internal consistency and test-retest reliability, as well as construct, discriminant, and convergent validity, were tested. Confirmatory factor analysis (CFA) was used to verify the original factor structure of the PedsQL™. Also, responsiveness to change in PedsQL™ scores over time was assessed. Cronbach's alpha coefficients ranged from α = 0.82 to α = 0.91. Test-retest reproducibility was satisfactory for all scales and the total scale score. The PedsQL proved good convergent validity with the SF-36. The PedsQL distinguished well between young adult patients and healthy young adults and also RA groups with different comorbidities. The CFA did not confirm the original four-factor model, instead, analyses revealed a best-fitting five-factor model for the PedsQL™ Young Adult Version. Repeated measures analysis of variance indicated that the PedsQL scale scores for young adults increased significantly over time. The Persian translation of the PedsQL™ 4.0 Generic Core Scales Young Adult Version demonstrated good psychometric properties in young adult patients with RA and can be recommended for the use in RA research in Iran.

Context Most adults with a psychiatric disorder first met diagnostic criteria during childhood and/or adolescence, yet specific homotypic and heterotypic patterns of prediction have not been firmly established. Objective To establish which childhood and adolescent psychiatric disorders predict particular young adult disorders when accounting for comorbidities, disaggregating similar disorders, and examining childhood and adolescent predictors separately. Design/Setting/Patients Eleven waves of data from the prospective population-based Great Smoky Mountains Study (N = 1,420) were used, covering children in the community ages 9−16, 19, and 21 years old. Outcome Common psychiatric disorders were assessed in childhood (ages 9 to 12) and adolescence (ages 13 to 16) with the Child and Adolescent Psychiatric Assessment, and in young adulthood (ages 19 and 21) with the Young Adult Psychiatric Assessment. Results Adolescent depression significantly predicted young adult depression in the bivariate analysis, but this effect was entirely accounted for by comorbidity of adolescent depression with adolescent oppositional defiant disorder, anxiety and substance disorders in adjusted analyses. Generalized anxiety and depression cross-predicted each other, and oppositional defiant disorder (but not conduct disorder) predicted later anxiety disorders and depression. Evidence of homotypic prediction was supported for substance use disorders, antisocial personality disorder (from conduct disorder) and anxiety disorders, although this effect was primary accounted for by DSM-III-R overanxious disorder. Conclusions Stringent tests of homotypic and heterotypic prediction patterns suggest a more developmentally and diagnostically nuanced picture in comparison with the previous literature. The putative link between adolescent and young adult depression was not supported. Oppositional defiant disorder was singular in being part of the developmental history of a wide range of young adult

Introduction National data indicate that the prevalence of non-cigarette tobacco product use is highest among young adults; however, little is known about their openness to use these products in the future and associated risk factors. This study sought to characterize openness to using non-cigarette tobacco products and associated factors among U.S. young adults. Methods In 2014, National Adult Tobacco Survey data (2012–2013) were analyzed to characterize openness to using the following tobacco products among all young adults aged 18–29 years (N=5,985): cigars; electronic cigarettes (“e-cigarettes”); hookah; pipe tobacco; chew, snuff, or dip; snus; and dissolvables. Among those who were not current users of each product, multivariable logistic regression was used to examine associations between demographics, cigarette smoking status, lifetime use of other non-cigarette products, perceived harm and addictiveness of smoking, and receipt of tobacco industry promotions and openness to using each product. Results Among all young adults, openness to using non-cigarette tobacco products was greatest for hookah (28.2%); e-cigarettes (25.5%); and cigars (19.1%). In multivariable analyses, which included non-current users of each product, non-current ever, current, and former smokers were more likely than never smokers to be open to using most examined products, as were men and adults aged 18–24 years. Receipt of tobacco industry promotions was associated with openness to using e-cigarettes; chew, snuff, or dip; and snus. Conclusions There is substantial openness to trying non-cigarette tobacco products among U.S. young adults. Young adults are an important population to consider for interventions targeting non-cigarette tobacco product use. PMID:26549502

Background The dietary limitation during pregnancy influences the growth and development of the fetus and offspring and their health into adult life. The mechanisms underlying the adverse effects of gestational protein restriction (GPR) in the development of the offspring hearts are not well understood. Objectives The aim of this study was to evaluate the effects of GPR on cardiac structure in male rat offspring at day 60 after birth (d60). Methods Pregnant Wistar rats were fed a normal-protein (NP, 17% casein) or low-protein (LP, 6% casein) diet. Blood pressure (BP) values from 60-day-old male offspring were measured by an indirect tail-cuff method using an electro sphygmomanometer. Hearts (d60) were collected for assessment of connexin 43 (Cx43) mRNA expression and morphological and morphometric analysis. Results LP offspring showed no difference in body weight, although they were born lighter than NP offspring. BP levels were significantly higher in the LP group. We observed a significant increase in the area occupied by collagen fibers, a decrease in the number of cardiomyocytes by 104 µm2, and an increase in cardiomyocyte area associated with an increased Cx43 expression. Conclusion GPR changes myocardial levels of Cx43 mRNA in male young adult rats, suggesting that this mechanism aims to compensate the fibrotic process by the accumulation of collagen fibers in the heart interstitium.

2010-03-01

The maximum isometric force production capacity of the fingers decreases with age. However, little information is available on age-related changes in dynamic motor capacity of individual fingers. The purpose of this study was to compare the dynamic motor function of individual fingers between elderly and young adults using rapid single-finger and double-finger tapping. Fourteen elderly and 14 young adults performed maximum frequency tapping by the index, middle, ring, or little finger (single-finger tapping) and with alternate movements of the index-middle, middle-ring, or ring-little finger-pair (double-finger tapping). The maximum pinch force between the thumb and each finger, tactile sensitivity of each fingertip, and time taken to complete a pegboard test were also measured. Compared with young subjects, the older subjects had significantly slower tapping rates in all fingers and finger-pairs in the tapping tasks. The age-related decline was also observed in the tactile sensitivities of all fingers and in the pegboard test. However, there was no group difference in the pinch force of any finger. The tapping rate of each finger did not correlate with the pinch force or tactile sensitivity for the corresponding finger in the elderly subjects. Maximum rate of finger tapping was lower in the elderly adults compared with the young adults. The decline of finger tapping ability in elderly adults seems to be less affected by their maximum force production capacities of the fingers as well as tactile sensitivities at the tips of the fingers.

To examine young adults' health care utilization and expenditures prior to the Affordable Care Act. We used 2009 Medical Expenditure Panel Survey to (1) compare young adults' health care utilization and expenditures of a full-spectrum of health services to children and adolescents and (2) identify disparities in young adults' utilization and expenditures, based on access (insurance and usual source of care) and other sociodemographic factors, including race/ethnicity and income. Young adults had (1) significantly lower rates of overall utilization (72%) than other age groups (83%-88%, p < .001), (2) the lowest rate of office-based utilization (55% vs. 67%-77%, p < .001) and (3) higher rate of emergency room visits compared with adolescents (15% vs. 12%, p < .01). Uninsured young adults had high out-of-pocket expenses. Compared with the young adults with private insurance, the uninsured spent less than half on health care ($1,040 vs. $2,150/person, p < .001) but essentially the same out-of-pocket expenses ($403 vs. $380/person, p = .57). Among young adults, we identified significant disparities in utilization and expenditures based on the presence/absence of a usual source of care, race/ethnicity, home language, and sex. Young adults may not be utilizing the health care system optimally by having low rates of office-based visits and high rates of emergency room visits. The Affordable Care Act provision of insurance for those previously uninsured or under-insured will likely increase their utilization and expenditures and lower their out-of-pocket expenses. Further effort is needed to address noninsurance barriers and ensure equal access to health services. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Porter, Jerlym S; Wesley, Kimberly M; Zhao, Mimi S; Rupff, Rebecca J; Hankins, Jane S

2017-10-01

The aim of this study was to explore perspectives of transition and transition readiness of young adult patients (YAs) with sickle cell disease (SCD) who have transitioned to adult health care. In all, 19 YAs with SCD (ages 18-30 years) participated in one of three focus groups and completed a brief questionnaire about transition topics. Transcripts were coded and emergent themes were examined using the social-ecological model of adolescent and young adult readiness for transition (SMART). Themes were consistent with most SMART components. Adult provider relationships and negative medical experiences emerged as salient factors. YAs ranked choosing an adult provider, seeking emergency care, understanding medications/medication adherence, knowing SCD complications, and being aware of the impact of health behaviors as the most important topics to include in transition programming. The unique perspectives of YAs can inform the development and evaluation of SCD transition programming by incorporating the identified themes. © The Author 2017.

Holmes, Louisa M; Ling, Pamela M

2017-03-01

To examine occupational differences in workplace exposure to secondhand smoke (SHS) among young adults in California. Data are taken from the 2014 Bay Area Young Adult Health Survey, a probabilistic multimode cross-sectional household survey of young adults, aged 18-26, in Alameda and San Francisco Counties. Respondents were asked whether they had been exposed to SHS 'indoors' or 'outdoors' at their workplace in the previous 7 days and also reported their current employment status, industry and occupation. Sociodemographic characteristics and measures of health perception and behaviour were included in the final model. Young adults employed in service (p<0.001), construction and maintenance (p<0.01), and transportation and material moving (p<0.05) sectors were more likely to report workplace SHS exposure while those reporting very good or excellent self-rated health were less likely (p<0.001). Despite California's clean indoor air policy, 33% of young adults in the San Francisco Bay Area still reported workplace SHS exposure in the past week, with those in lower income occupations and working in non-office environments experiencing the greatest exposure. Closing the gaps that exempt certain types of workplaces from the Smoke-Free Workplace Act may be especially beneficial for young adults. Published by the BMJ Publishing Group Limited.

Messier, Claude; Awad-Shimoon, Nesrine; Gagnon, Michèle; Desrochers, Alain; Tsiakas, Maria

2011-09-12

Several studies have documented an increased incidence of dementia among diabetic patients. In addition, impaired glucose regulation in both, younger and older adults, has been shown to be associated with neuropsychological deficits, particularly of episodic memory. The main purpose of this study was to examine this association in a large sample of young nondiabetic adults. All participants underwent a glucose tolerance test together with measures of insulin levels and lipids. Regression analyses revealed that glucoregulatory indices based on evoked glucose levels were significantly associated with the verbal memory performance of 122 young adults, independent of demographic and vascular risk factors. Participants were assessed after drinking glucose or saccharin, using a repeated-measures design. There was no effect of glucose on cognitive performance. Glucoregulatory indices calculated on the basis of insulin levels or fasting glucose levels explained less cognitive variability compared to indices based on evoked glucose levels. Cardiovascular risk factors were associated with hyperinsulinemia but these factors were not associated with cognitive performance in this young adult group. These findings suggest that cognitive decrements are observable in young, nondiabetic adults, prior to the onset of impaired glucose regulation and diabetes. Copyright © 2011 Elsevier B.V.

Changes in contractile properties and action potentials of motor units in the rat medial gastrocnemius muscle during maturation.

PubMed

Dobrzynska, Z; Celichowski, J

2016-02-01

The early phase of development of muscles stops following the disappearance of embryonic and neonatal myosin and the elimination of polyneuronal innervation of muscle fibres with the formation of motor units (MUs), but later the muscle mass still considerably increases. It is unknown whether the three types are visible among newly formed MUs soon after the early postnatal period and whether their proportion is similar to that in adult muscle. Moreover, the processes responsible for MU-force regulation by changes in motoneuronal firing rate as well as properties of motor unit action potentials (MUAPs) during maturation are unknown. Three groups of Wistar rats were investigated - 1 month old, 2 months old and the adult, 9 months old. The basic contractile properties and action potentials of MUs in the medial gastrocnemius (MG) muscle were analysed. The three types of MUs were distinguishable in all age groups, but higher proportion of slow MUs was noticed in young rats (29%, 18% and 11% in 1, 2 and 9 months rats, respectively). The fatigue index for fast fatigable MUs in 1 month old rats was about 2 times higher than in 9 months old rats. The twitch time parameters of fast MUs were shortened during the maturation; for these units, the force-frequency curves in young rats were shifted towards lower frequencies, which suggested that fast motoneurons of young animals generate lower firing rates. Higher twitch-to-tetanus ratios noted for the three MU types in young rats suggested the smaller role of rate coding in force regulation processes, and the higher role of MU recruitment in young rats. No significant differences in MUAP parameters between two groups of young and adult animals were observed. Concluding, the maturation process evokes deeper changes in fast MUs than in slow ones.

What Are Young Adults Saying About Mental Health? An Analysis of Internet Blogs

Westra, Henny A; Eastwood, John D; Barnes, Kirsten L

2012-01-01

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

Development of acute hydrocephalus does not change brain tissue mechanical properties in adult rats, but in juvenile rats

PubMed Central

Pong, Alice C.; Jugé, Lauriane; Bilston, Lynne E.; Cheng, Shaokoon

2017-01-01

Introduction Regional changes in brain stiffness were previously demonstrated in an experimental obstructive hydrocephalus juvenile rat model. The open cranial sutures in the juvenile rats have influenced brain compression and mechanical properties during hydrocephalus development and the extent by which closed cranial sutures in adult hydrocephalic rat models affect brain stiffness in-vivo remains unclear. The aims of this study were to determine changes in brain tissue mechanical properties and brain structure size during hydrocephalus development in adult rat with fixed cranial volume and how these changes were related to brain tissue deformation. Methods Hydrocephalus was induced in 9 female ten weeks old Sprague-Dawley rats by injecting 60 μL of a kaolin suspension (25%) into the cisterna magna under anaesthesia. 6 sham-injected age-matched female SD rats were used as controls. MR imaging (9.4T, Bruker) was performed 1 day before and then at 3 days post injection. T2-weighted anatomical MR images were collected to quantify ventricle and brain tissue cross-sectional areas. MR elastography (800 Hz) was used to measure the brain stiffness (G*, shear modulus). Results Brain tissue in the adult hydrocephalic rats was more compressed than the juvenile hydrocephalic rats because the skulls of the adult hydrocephalic rats were unable to expand like the juvenile rats. In the adult hydrocephalic rats, the cortical gray matter thickness and the caudate-putamen cross-sectional area decreased (Spearman, P < 0.001 for both) but there were no significant changes in cranial cross-sectional area (Spearman, P = 0.35), cortical gray matter stiffness (Spearman, P = 0.24) and caudate-putamen (Spearman, P = 0.11) stiffness. No significant changes in the size of brain structures were observed in the controls. Conclusions This study showed that although brain tissue in the adult hydrocephalic rats was severely compressed, their brain tissue stiffness did not change significantly

The purpose of this study was to examine sociodemographic and health care-related characteristics of young adults covered through the Affordable Care Act (ACA)-dependent coverage expansion. Our sample consisted of 36,802 young adults aged 19-25 years from 2011 to 2014 National Health Interview Survey. Sociodemographic differences among young adults with the four insurance types were described: privately insured under parents, privately insured under self/spouse, publicly insured, and uninsured. Multivariable logistic models were fitted to compare those covered under parent with those covered through other traditional insurance types, in terms of the following outcomes: health status, health behaviors, insurance history and experience, access to care, care utilization, and receipt of preventive service, controlling for sociodemographic factors. Young adults who were covered under their parents' insurance were most likely to be college students and non-Hispanic whites. These young adults also had more stable insurance, better access to care, better care utilization patterns, and reported better health status, compared to their peers. The beneficiaries of the ACA-dependent coverage expansion were more likely to be college students from families with high socioeconomic status. Coverage under parents was associated with improved access to care and health outcomes among young adults. The enrollees through the ACA represent the healthiest subgroup of young adults and those with the best care utilization patterns, suggesting that the added cost relative to premium for insurers from this population will likely be minimal.

A case of a young adult patient in the days immediately after a cancer diagnosis illustrates the critical importance of three interrelated core coordinating mechanisms—closed-loop communication, shared mental models, and mutual trust—of teamwork in an adolescent and young adult multidisciplinary oncology team. The case illustrates both the opportunities to increase team member coordination and the problems that can occur when coordination breaks down. A model for teamwork is presented, which highlights the relationships among these coordinating mechanisms and demonstrates how balance among them works to optimize team function and patient care. Implications for clinical practice and research suggested by the case are presented. PMID:27624944

The survival gap between adolescents and young adults (AYAs) with hematological malignancies persists in many countries. To determine to what extent it does in Japan, we investigated survival and treatment regimens in 211 Japanese AYAs (15-29 years) in the Osaka Cancer Registry diagnosed during 2001-2005 with hematological malignancies, and compared adolescents (15-19 years) with young adults (20-29 years). AYAs with acute lymphoblastic leukemia (ALL) had a poor 5-year survival (44%), particularly young adults (29% vs. 64% in adolescents, p = 0.01). Additional investigation for patients with ALL revealed that only 19% of young adults were treated with pediatric treatment regimens compared with 45% of adolescents (p = 0.05). Our data indicate that we need to focus on young adults with ALL and to consider establishing appropriate cancer care system and guidelines for them in Japan.

Self-reference enhances relational memory in young and older adults.

Hou, Mingzhu; Grilli, Matthew D; Glisky, Elizabeth L

2017-11-27

The present study investigated the influence of self-reference on two kinds of relational memory, internal source memory and associative memory, in young and older adults. Participants encoded object-location word pairs using the strategies of imagination and sentence generation, either with reference to themselves or to a famous other (i.e., George Clooney or Oprah Winfrey). Both young and older adults showed memory benefits in the self-reference conditions compared to other-reference conditions on both tests, and the self-referential effects in older adults were not limited by low memory or executive functioning. These results suggest that self-reference can benefit relational memory in older adults relatively independently of basic memory and executive functions.

Health insurance, patient protection and Affordable Care Act, and young adults.

PubMed

Dodich, Colleen; Patel, Dilip

2013-12-01

In summary, the ACA aims to correct some of the shortcomings of our current health insurance systems. It aims to make health insurance more affordable and more accessible and the health insurance systems easier to navigate. For the young adult population, it aims to protect more individuals by allowing them to stay on their parent's insurance longer and by making it easier to choose an insurance plan that is right for them. Those with preexisting medical conditions do not have to worry about being excluded from a health plan because of their medical history. The law is also making health insurance mandatory, which may help prevent young adults who fall ill from incurring large medical bills. Initial outcomes from the implementation of the ACA have shown both positive and negative responses. All in all, it is giving young adults more options when it comes to obtaining health insurance. As part of discussion with adolescents and young adults, physicians may take into consideration key points summarized in Table 4.

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

Recruiting Young Adult Cancer Survivors for Behavioral Research

PubMed Central

Horowitz, Santina; Marcus, Bess

2012-01-01

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

Cilostazol enhances atorvastatin-induced vasodilation of female rat aorta during aging.

PubMed

Nurullahoğlu-Atalık, K E; Kutlu, S; Solak, H; Koca, R Özen

2017-09-01

Statins have cholesterol-independent effects including an increased vascular nitric oxide activity and are commonly used by patients with cardiovascular disease. Such patients frequently have cardiovascular diseases, which may be treated with cilostazol, a platelet aggregation inhibitor. This study was designed to investigate whether combined use of cilostazol would increase the inhibitory effect of statin on vascular smooth muscle and how maturation would affect these responses. Female Wistar rats, aged 3-4 months (young) and 14-15 months (adult), were sacrificed by cervical dislocation and the thoracic aorta was dissected and cut into 3- to 4-mm-long rings. The rings were mounted under a resting tension of 1 g in a 20-ml organ bath filled with Krebs-Henseleit solution. Rings were precontracted with phenylephrine (10 -6  M), and the presence of endothelium was confirmed with acetylcholine (10 -6  M). Then, the concentration-response curves were obtained for atorvastatin alone (10 -10 to 3 × 10 -4  M; control) and in the presence of cilostazol (10 -6  M) in young and adult rat aortas. This experimental protocol was also carried out in aorta rings, which had been pretreated with N G -nitro-l-arginine methyl ester (l-NAME, 10 -4  M). Atorvastatin induced concentration-dependent relaxations in young and adult rat thoracic aorta rings precontracted with phenylephrine. The pIC 50 value of atorvastatin was significantly decreased in adult rat aortas. In addition, pretreatment of aortas with cilostazol enhanced the potency of atorvastatin in both young and adult aortas. Incubation with l-NAME did not completely eliminate the relaxations to atorvastatin in the presence of cilostazol. These results suggest that combined application of cilostazol with atorvastatin was significantly more potent than atorvastatin alone. Combined drug therapy may be efficacious in delaying the occurrence of cardiovascular events.

The prevalence of severe obesity among children and young adults has increased over the past decade. Although the prevalence of cardiometabolic risk factors is relatively low among children and young adults who are overweight or obese, those with more severe forms of obesity may be at greater risk. We performed a cross-sectional analysis of data from overweight or obese children and young adults 3 to 19 years of age who were included in the National Health and Nutrition Examination Survey from 1999 through 2012 to assess the prevalence of multiple cardiometabolic risk factors according to the severity of obesity. Weight status was classified on the basis of measured height and weight. We used standard definitions of abnormal values for total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein cholesterol, triglycerides, blood pressure, glycated hemoglobin, and fasting glucose and report the prevalence of abnormal values in children and young adults according to weight status. Among 8579 children and young adults with a body-mass index at the 85th percentile or higher (according to the Centers for Disease Control and Prevention growth charts), 46.9% were overweight, 36.4% had class I obesity, 11.9% had class II obesity, and 4.8% had class III obesity. Mean values for some, but not all, cardiometabolic variables were higher with greater severity of obesity in both male and female participants, and the values were higher in male participants than in female participants; for HDL cholesterol, the mean values were lower with greater severity of obesity. Multivariable models that controlled for age, race or ethnic group, and sex showed that the greater the severity of obesity, the higher the risks of a low HDL cholesterol level, high systolic and diastolic blood pressures, and high triglyceride and glycated hemoglobin levels. Severe obesity in children and young adults was associated with an increased prevalence of cardiometabolic risk factors

Objective This study assessed whether smoking in the movies was associated with smoking in young adults. Methods A national web-enabled cross-sectional survey of 1528 young adults, aged 18–25, was performed between September and November 2005. Logistic regression and path analysis using probit regression were used to assess relationships between exposure to smoking in the movies and smoking behavior. Analysis was completed in December 2006. Results Exposure to smoking in the movies predicted current smoking. The adjusted odds of current smoking increased by a factor of 1.21 for each quartile increase in exposure to smoking (p<0.01) in the movies, reaching 1.77 for the top exposure quartile. The unadjusted odds of established smoking (100+ cigarettes with current smoking) increased by 1.23 per quartile (p<0.001) of exposure, reaching 1.86 for the top quartile. This effect on established smoking was mediated by two factors related to smoking in the movies: positive expectations about smoking and exposure to friends and relatives who smoked, with positive expectations accounting for about two thirds of the effect. Conclusions The association between smoking in the movies and young adult smoking behavior exhibited a dose–response relationship; the more a young adult was exposed to smoking in the movies, the more likely he or she would have smoked in the past 30 days or have become an established smoker.

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

2013-04-01

Passage of the U.S. Family Smoking Prevention and Tobacco Control Act in 2009 led to a ban on the sale of flavored cigarettes, largely because of studies showing targeting of these products to youth and young adults. There are no current restrictions on the marketing or sale of noncigarette or new nontraditional smokeless tobacco products (such as snus and dissolvable products), which are available in more than 45 flavors. To determine the prevalence of flavored tobacco use, dual use of flavored and menthol tobacco products, and sociodemographic predictors of flavored tobacco product use in young adults aged 18-34 years (N=4196). The current study utilizes data from Legacy's Young Adult Cohort Study, a nationally representative sample collected in January 2012. Data were analyzed using Stata IC 11.0 in June 2012. Overall, 18.5% of tobacco users report using flavored products, and dual use of menthol and flavored product use ranged from 1% (nicotine products) to 72% (chewing tobacco). In a multivariable model controlling for menthol use, younger adults were more likely to use flavored tobacco products (OR=1.89, 95% CI=1.14, 3.11), and those with a high school education had decreased use of flavored products (OR=0.56; 95% CI=0.32, 0.97). Differences in use may be due to the continued targeted advertising of flavored products to young adults and minorities. Those most likely to use flavored products are also those most at risk of developing established tobacco-use patterns that persist through their lifetime.

U.S. trends in population health suggest alarming disparities among young adults, who are less healthy across most measureable domains than their counterparts in other high-income countries; these international comparisons are particularly troubling for women. To deepen our understanding of gender disparities in health and underlying behavioral contributions, we document gender-specific clusters of health behavior among U.S. young adults using nationally representative data from the National Longitudinal Study of Adolescent to Adult Health. We find high levels of poor health behavior, but especially among men; 40 percent of men clustered into a group characterized by unhealthy behavior (e.g., poor diet, no exercise, substance use), compared to only 22 percent of women. Additionally, women tend to age out of unhealthy behaviors in young adulthood more than men. Further, we uncover gender differences in the extent to which sociodemographic position and adolescent contexts inform health behavior clustering. For example, college education was more protective for men, whereas marital status was equally protective across gender. Parental drinking mattered for health behavior clustering among men, whereas peer drinking mattered for clustering among women. We discuss these results in the context of declining female advantage in U.S. health and changing young adult social and health contexts.

2011-01-01

Methylphenidate is a psychostimulant widely used in the treatment of attention deficit hyperactivity disorder. In this study, the effects of two nonstereotypy-inducing doses of methylphenidate (2.5 and 5.0 mg/kg s.c.) were examined in periadolescent [postnatal days (P) 35 and 42] and young adult (P70), male Long-Evans rats using a three-period locomotor activity paradigm that affords inferences about exploration, habituation, and attention to a novel stimulus (an “alcove”) in a familiar environment in a single test session. In the first test period, P35 and P42 rats were more active than P70 rats, and methylphenidate increased locomotion in a dose-related manner. The introduction of a novel spatial stimulus in the third test period revealed a significant interaction of dose and age such that P70 rats exhibited dose-related increases in distance traveled, but P35 rats did not. Furthermore, methylphenidate dose-relatedly disrupted the rats' tendency to spend increasing amounts of time in the alcove across the test period at P70 but not at P35. Brain and serum methylphenidate concentrations were significantly lower at P35 than at P70, with intermediate levels at P42. Developmental differences in dopaminergic neurochemistry were also observed, including increased dopamine content in the caudate-putamen, nucleus accumbens, and frontal cortex and decreased densities of D1-like receptors in the frontal cortex in P70 than in P42 rats. These results raise the possibility that children and adults may respond differently when treated with this drug, particularly in situations involving response to novelty and that these effects involve developmental differences in pharmacokinetics and dopaminergic neurochemistry.

Young adults with type 1 diabetes transitioning from pediatric to adult care are at risk for adverse outcomes. Our objective was to describe experiences, resources, and barriers reported by a national sample of adult endocrinologists receiving and caring for young adults with type 1 diabetes. We fielded an electronic survey to adult endocrinologists with a valid e-mail address identified through the American Medical Association Physician Masterfile. We received responses from 536 of 4,214 endocrinologists (response rate 13%); 418 surveys met the eligibility criteria. Respondents (57% male, 79% Caucasian) represented 47 states; 64% had been practicing >10 years and 42% worked at an academic center. Only 36% of respondents reported often/always reviewing pediatric records and 11% reported receiving summaries for transitioning young adults with type 1 diabetes, although >70% felt that these activities were important for patient care. While most respondents reported easy access to diabetes educators (94%) and dietitians (95%), fewer (42%) reported access to mental health professionals, especially in nonacademic settings. Controlling for practice setting and experience, endocrinologists without easy access to mental health professionals were more likely to report barriers to diabetes management for young adults with depression (odds ratio [OR] 5.3; 95% CI 3.4, 8.2), substance abuse (OR 3.5; 95% CI 2.2, 5.6), and eating disorders (OR 2.5; 95% CI 1.6, 3.8). Our findings underscore the need for enhanced information transfer between pediatric and adult providers and increased mental health referral access for young adults with diabetes post-transition. © 2016 by the American Diabetes Association.

Aging is characterized by progressive decline in physiological and body function due to increase in oxidative damage. Gelam honey has been accounted to have high phenolic and nonphenolic content to attenuate oxidative damage. This study was to determine the effect of local gelam honey on oxidative damage of aged rats. Twenty-four male Spraque-Dawley rats were divided into young (2 months) and aged (19 months) groups. Each group was further divided into control (fed with plain water) and supplemented with 2.5 mg/kg body weight of gelam honey for 8 months. DNA damage level was determined by comet assay and plasma malondialdehyde (MDA) by high performance liquid chromatography (HPLC). The activity of blood and cardiac antioxidant enzymes was determined by spectrophotometer. The DNA damage and MDA level were reduced in both gelam honey supplemented groups. Gelam honey increases erythrocytes CAT and cardiac SOD activities in young and cardiac CAT activity in young and aged groups. The DNA damage was increased in the aged group compared to young group, but reduced at the end of the study. The decline of oxidative damage in rats supplemented with gelam honey might be through the modulation of antioxidant enzyme activities. PMID:25505937

Advances in care and treatment of adolescents/young adults with HIV infection have made survival into adulthood possible, requiring transition to adult care. Researchers have documented that the transition process is challenging for adolescents/young adults. To ensure successful transition, a formal transition protocol is needed. Despite existing research, little quantitative evaluation of the transition process has been conducted. The purpose of the study was to pilot test the "Movin' Out" Transitioning Protocol, a formalized protocol developed to assist transition to adult care. A retrospective medical/nursing record review was conducted with 38 clients enrolled in the "Movin' Out" Transitioning Protocol at a university-based adolescent medicine clinic providing care to adolescents/young adults with HIV infection. Almost half of the participants were able to successfully transition to adult care. Reasons for failure to transition included relocation, attrition, lost to follow-up, and transfer to another adult service. Failure to transition to adult care was not related to adherence issues, X(2) (1, N=38)=2.49, p=.288; substance use, X(2) (1, N=38)=1.71, p=.474; mental health issues, X(2) (1, N=38)=2.23, p=.322; or pregnancy/childrearing, X(2) (1, N=38)=0.00, p=.627). Despite the small sample size, the "Movin' Out" Transitioning Protocol appears to be useful in guiding the transition process of adolescents/young adults with HIV infection to adult care. More research is needed with a larger sample to fully evaluate the "Movin' Out" Transitioning Protocol. Copyright © 2015 Elsevier Inc. All rights reserved.

Reports on prenatal exposure to some of the first generation antipsychotic drugs like, haloperidol, their effects on fetal neurotoxicity and functional impairments in the offspring, are well documented. But studies on in utero exposure to second generation antipsychotics, especially quetiapine, and its effects on fetal neurotoxicity, apoptotic neurodegeneration, postnatal developmental delay and neurobehavioral consequences are lacking. Therefore, the present study was undertaken to evaluate the effect of prenatal administration to equivalent therapeutic doses of quetiapine on neuro-architectural abnormalities, neurohistopathological changes, apoptotic neurodegeneration in fetal hippocampus, and postnatal development and growth as well as its long-lasting imprint on cognitive impairment in young-adult offspring. Pregnant Wistar rats (n=24) were exposed to selected doses (55 mg, 80 mg and 100mg/kg) of quetiapine, equivalent to human therapeutic doses, from gestation day 6 to 21 orally with control subjects. Half of the pregnant subjects of each group were sacrificed at gestation day 21 for histopathological, confocal and electron microscopic studies and rest of the dams were allowed to deliver naturally. Their pups were reared postnatally up to 10 weeks of age for neurobehavioral observations. In quetiapine treated groups, there was significant alterations in total and differential thickness of three typical layers of hippocampus associated with neuronal cells deficit and enhanced apoptotic neurodegeneration in the CA1 area of fetal hippocampus. Prenatally drug treated rat offspring displayed post-natal developmental delay till postnatal day 70, and these young-adult rats displayed cognitive impairment in Morris water maze and passive avoidance regimes as long-lasting impact of the drug. Therefore, quetiapine should be used with cautions considering its developmental neurotoxicological and neurobehavioral potential in animal model, rat. Copyright © 2015 Elsevier

To evaluate one of the first implemented provisions of the Patient Protection and Affordable Care Act (ACA), which permits young adults up to age 26 to enroll as dependents on a parent's private health plan. Nearly one-in-three young adults lacked coverage before the ACA. STUDY DESIGN, METHODS, AND DATA: Data from the Current Population Survey 2005-2011 are used to estimate linear probability models within a difference-in-differences framework to estimate how the ACA affected coverage of eligible young adults compared to slightly older adults. Multivariate models control for individual characteristics, economic trends, and prior state-dependent coverage laws. This ACA provision led to a rapid and substantial increase in the share of young adults with dependent coverage and a reduction in their uninsured rate in the early months of implementation. Models accounting for prior state dependent expansions suggest greater policy impact in 2010 among young adults who were also eligible under a state law. ACA-dependent coverage expansion represents a rare public policy success in the effort to cover the uninsured. Still, this policy may have later unintended consequences for premiums for alternative forms of coverage and employer-offered rates for young adult workers. © Health Research and Educational Trust.
