RESUMO
OBJECTIVE: To establish whether physical fitness and cognitive self-perceptions act as mediators in the link between global fitness and cognitive performance measured objectively in adolescents. We also compared differences across sex. METHODS: A total of 1296 adolescents (50 % girls) from grades 5 to 8 (ages 10-14) participated in this cross-sectional study. The ALPHA-fitness test battery assessed physical fitness, comprising cardiorespiratory, speed-agility, and muscular fitness components. We used the 1-5-point International Fitness Scale for physical fitness self-perception, and the 1-10 scale for cognitive performance self-perception. Objective cognitive performance was assessed using a neurocognitive battery consisting of eight tasks. Using principal component analysis, these tasks were grouped into three domains: attention, working memory, and problem solving. We examined three serial mediation models adjusted for sex, standardized body mass index, maturation, and school vulnerability index. RESULTS: Physical fitness and cognitive self-perceptions mediated the effects on attention (B = .0027, CI = .0011 to .0047), memory (B = .0025; CI = .0003 to .0055 and B = .0035; CI = .0009 to .0063), and problem-solving (B = -.0137; CI = -.0231 to -.0052 and B = .0072; CI = .0043 to .0106). By sex, boys showed mediation in all domains, while girls only showed mediation in problem-solving. CONCLUSIONS: Adolescents' perceptions play a crucial and positive mediating role in linking objective measures of physical fitness to cognitive performance outcomes, particularly when self-perceptions of physical fitness and cognition are considered together. Therefore, educating families and school/health environments about the importance of adolescent perceptions, while fostering self-awareness and reinforcing their capabilities, is essential.
RESUMO
Objective: To determine how cognitive domains mediate the link between fitness components, their global score (GFS), and adolescents' academic achievement (ACA) across various school subjects. Methods: In this study, 1,296 adolescents aged 10-14 participated. GFS was computed by three fitness components (strength, muscular, and cardiorespiratory fitness) through the ALPHA-fitness test battery. ACA was determined by five school subjects (Language, English, Mathematics, Science, and History) and two academic scores (a) "Academic Average" (five subjects) and (b) "Academic-PISA" (Language, Mathematics, and Science). A principal component analysis was performed to establish four factors (working memory [WM], cognitive flexibility [CF], inhibitory control [IC], and fluid reasoning [FR]). A parallel mediation approach was implemented with 5,000 bootstrapped samples controlled for sex, maturity, central obesity, having breakfast before cognitive tasks, schools, and school vulnerability. Total, direct, indirect effects, and mediation percentages were estimated. Results: Overall, the finding showed a full parallel mediation effect for Language (92.5%) and English (53.9%), while a partial mediation for Mathematics (43.0%), Science (43.8%), History (45.9%), "Academic Average" (50.6%), and "Academic-PISA" (51.5%). In particular, WM, IC, and FR mediated all school subjects except mathematics, where IC was not significant. CF has not mediated any relationship between GF and academic performance. Conclusion: This study underscores the pivotal role of cognitive domains, specifically WM, IC, and FR, in mediating the link between physical fitness and academic performance in adolescents. These insights have relevant implications for educational and public health policies.
RESUMO
OBJECTIVE: To carry out and evaluate a communications campaign (La CLAve) to reduce the duration of untreated psychosis (DUP) in a U.S. Latinx community. METHOD: We employed evidence-based messaging in multiple media outlets. We recruited 132 Latinxs with first-episode psychosis (FEP) and caregivers seeking mental health care within a high-density Latinx community. We evaluated the campaign's dissemination, the extent to which the community received the campaign message, and the campaign outcome. We tested whether DUP (number of weeks) changed across three time periods (16-month baseline, 2-year campaign, and 16-month postcampaign) and whether participants' language background (primarily Spanish speaking or English speaking) moderated change in DUP. RESULTS: The campaign was disseminated widely. During the height of the campaign over a 1-year period, our team distributed 22,039 brochures and performed 740 workshops. The campaign message was received by the community as noted for example by increases in the number of unduplicated weekly calls to the campaign's 1-800 number. Applying square root transformations to DUP, we found a significant main effect for language background but not for campaign period nor their interaction. The unadjusted mean DUP for Spanish-speaking persons with FEP was more than twice as high as the mean DUP for English-speaking persons with FEP. CONCLUSION: Spanish-speaking Latinxs with FEP are especially in need of early psychosis treatment. The campaign reached the community but additional steps are needed to reduce treatment delay. Greater attention is needed to increase access to early intervention services for communities of color. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

AIM: Initiatives aimed at reducing the duration of untreated psychosis (DUP) attempt to increase the community's level of psychosis literacy. Most of these efforts, however, have failed to reduce DUP. One plausible explanation is that the campaigns do not actually increase psychosis literacy. To date, there have been few efforts to assess whether the campaign messaging does indeed increase psychosis literacy prior to or during the campaign. This study evaluated whether the message of the La CLAve DUP reduction program delivered during the campaign increased the psychosis literacy of a U.S. Latinx community. METHODS: The sample consisted of 81 Latinx community residents aged 15-84. Two community health educators of the La CLAve campaign facilitated workshops using a narrative film to initiate a conversation in the community about the signs of psychosis and the importance of professional help-seeking early in the illness course. Psychosis literacy was assessed via questionnaires pertaining to a hypothetical vignette administered before and after the workshops. RESULTS: The psychosis literacy of participants increased after the workshops in several domains. Participants' knowledge of multiple psychotic symptoms, self-efficacy in their ability to recognize psychosis in others, and correct attributions of a hypothetical vignette's psychotic symptoms significantly increased. No changes were observed in recommendations for professional help-seeking. CONCLUSIONS: These findings provide support for the effectiveness of the La CLAve messaging in increasing psychosis literacy of U.S. Latinx community residents. Evidence-based campaign messaging is needed to increase the success of DUP reduction programs especially among underserved communities.

INTRODUCTION: Gender and ethnic differences exist in suicidal ideation, plan, and attempt among adolescents in the U.S. However, limited research has used theoretically-informed approaches to integrate how cultural and classic risk factors together account for suicide-related pathways among vulnerable populations. Informed by the interpersonal theory of suicide, the present cross-sectional study examined gender differences in the association between a cultural (i.e., discrimination) and classic (i.e., depressive symptomatology) risk factor, and suicidality among youth of Latin American heritage. METHODS: A total of 390 Latinx adolescents (ages 13-18; 50% female) attending a high school in Southern California, U.S.A. completed a series of questionnaires that included measures of depressive symptoms, suicidality (including ideation, past attempts, and likelihood of future behavior), perceived discrimination, and demographics. RESULTS: We found that discrimination was associated with increased suicidality among Latinx adolescents. The discrimination-suicidality association was stronger for girls versus boys, such that girls who experienced greater discrimination demonstrated the highest levels of suicidality. Although depression was also significantly associated with suicidality, the discrimination x gender interaction was found above and beyond the main effect of depressive symptomatology and covariates. Additional analyses revealed significant gender and moderation effects only for suicidal ideation and not for attempts. CONCLUSIONS: These findings indicate that the relationship between discrimination and suicidality (particularly ideation) is more pronounced for Latinx girls than boys. This study also highlights the importance of drawing on theory-driven and culturally informed work that incorporates classic and cultural correlates of suicidality among diverse subpopulations.

OBJECTIVE: The study examined psychosis literacy among Latinos with first-episode psychosis (FEP) and their caregivers. The authors tested a model that knowledge of psychosis and attribution of illness to psychosis predicted professional help seeking in a cross-sectional design. METHODS: The sample (N=148) consisted of 79 Latino consumers who met criteria for a clinical diagnosis of a psychotic disorder and 69 family caregivers. Participants watched a four-minute narrative about a woman with psychosis and were asked to identify the symptoms of serious mental illness (knowledge of psychosis), describe the character's problem and whether she had a serious mental illness (illness attribution), and offer suggestions about what the parents should do (help seeking). Responses to the open-ended questions were reliably coded by two trained raters. RESULTS: Consumers reported low psychosis literacy across all indices (e.g., only 8% included delusions in their knowledge of serious mental illness). Compared with consumers, caregivers reported significantly greater psychosis literacy across most indices, although relatively few reported knowledge of delusions (28%) and disorganized speech (36%). Logistic regression analyses found that caregivers were more than twice as likely as consumers to suggest that the parents seek professional help. Among both consumers and caregivers, greater knowledge of psychosis and attribution of symptoms to serious mental illness were associated with increased likelihood of recommending professional help seeking. CONCLUSIONS: Community campaigns and psychoeducation interventions within clinical settings are needed to improve psychosis literacy among Latinos with FEP. Increasing knowledge of psychosis and facilitating attributions of psychotic symptoms to serious mental illness have the potential to promote professional help seeking.

BACKGROUND: Nicotine improves attention and processing speed in individuals with schizophrenia. Few studies have investigated the effects of nicotine on cognitive control. Prior functional magnetic resonance imaging (fMRI) research demonstrates blunted activation of dorsal anterior cingulate cortex (dACC) and rostral anterior cingulate cortex (rACC) in response to error and decreased post-error slowing in schizophrenia. METHODS: Participants with schizophrenia (n = 13) and healthy controls (n = 12) participated in a randomized, placebo-controlled, crossover study of the effects of transdermal nicotine on cognitive control. For each drug condition, participants underwent fMRI while performing the stop signal task where participants attempt to inhibit prepotent responses to "go (motor activation)" signals when an occasional "stop (motor inhibition)" signal appears. Error processing was evaluated by comparing "stop error" trials (failed response inhibition) to "go" trials. Resting-state fMRI data were collected prior to the task. RESULTS: Participants with schizophrenia had increased nicotine-induced activation of right caudate in response to errors compared to controls (DRUG × GROUP effect: p corrected < 0.05). Both groups had significant nicotine-induced activation of dACC and rACC in response to errors. Using right caudate activation to errors as a seed for resting-state functional connectivity analysis, relative to controls, participants with schizophrenia had significantly decreased connectivity between the right caudate and dACC/bilateral dorsolateral prefrontal cortices. CONCLUSIONS: In sum, we replicated prior findings of decreased post-error slowing in schizophrenia and found that nicotine was associated with more adaptive (i.e., increased) post-error reaction time (RT). This proof-of-concept pilot study suggests a role for nicotinic agents in targeting cognitive control deficits in schizophrenia.

Introduction: Smoking is associated with significant morbidity and mortality. Understanding the neurobiology of the rewarding effects of nicotine promises to aid treatment development for nicotine dependence. Through its actions on mesolimbic dopaminergic systems, nicotine engenders enhanced responses to drug-related cues signaling rewards, a mechanism hypothesized to underlie the development and maintenance of nicotine addiction. Methods: We evaluated the effects of acute nicotine on neural responses to anticipatory cues signaling (nondrug) monetary reward or loss among 11 nonsmokers who had no prior history of tobacco smoking. In a double-blind, crossover design, participants completed study procedures while wearing nicotine or placebo patches at least 1 week apart. In each drug condition, participants underwent functional magnetic resonance imaging while performing the monetary incentive delay task and performed a probabilistic monetary reward task, probing reward responsiveness as measured by response bias toward a more frequently rewarded stimulus. Results: Nicotine administration was associated with enhanced activation, compared with placebo, of right fronto-anterior insular cortex and striatal regions in response to cues predicting possible rewards or losses and to dorsal anterior cingulate for rewards. Response bias toward rewarded stimuli correlated positively with insular activation to anticipatory cues. Conclusion: Nicotinic enhancement of monetary reward-related brain activation in the insula and striatum in nonsmokers dissociated acute effects of nicotine from effects on reward processing due to chronic smoking. Reward responsiveness predicted a greater nicotinic effect on insular activation to salient stimuli. Implications: Previous research demonstrates that nicotine enhances anticipatory responses to rewards in regions targeted by midbrain dopaminergic systems. The current study provides evidence that nicotine also enhances responses to rewards and losses in the anterior insula. A previous study found enhanced insular activation to rewards and losses in smokers and ex-smokers, a finding that could be due to nicotine sensitization or factors related to current or past smoking. Our finding of enhanced anterior insula response after acute administration of nicotine in nonsmokers provides support for nicotine-induced sensitization of insular response to rewards and losses.

Objetivo: Determinar el grado de información sobre la infección genital por el virus papiloma humano que poseen pacientes que asistieron al Servicio de Ginecología de la Maternidad Concepción Palacios entre noviembre 2012 y octubre 2013. Métodos: Estudio prospectivo, descriptivo, transversal. Se incluyó una muestra probabilística de 372 pacientes a quienes se les aplicó una encuesta. Resultados: 257 pacientes (69,1 %) poseían un grado de información bueno; 18 (4,8 %) regular y 97 (26,1 %) malo. Entre las primeras, la edad promedio fue de 41 ± 12 años y 58,8 % pertenecían al estrato IV mientras que, para las últimas, la edad promedio fue de 47 ± 15 años y 64,9 % pertenecían al estrato socioeconómico IV (P=0,000). Entre las pacientes con mayor nivel de conocimiento, 56,8 % tenían entre 26 y 45 años, 58,8 % tenían primaria aprobada y 58,8 % tenían diagnóstico previo de infección por virus de papiloma humano. Entre aquellas con bajo nivel de conocimiento, 36,1 % tenían entre 26 y 45 años, 77,3 % tenían primaria aprobada y 19,6 tenían diagnóstico previo de la infección. Respecto a la información que poseen, 268 saben que es una infección de trasmisión sexual, 251 que el preservativo protege contra la infección, 222 asocian la infección con el inicio temprano de actividad sexual, 261 con el número de parejas sexuales y 212 con el cáncer de cuello uterino. Conclusiones: Un alto porcentaje de pacientes presentan un buen grado de información sobre la infección genital por virus de papiloma humano.
Objective: To determine the knowledge about the genital infection by the human papillomavirus, of patients attending the gynecology department of the Maternity Concepción Palacios in the period November 2012 - October 2013. Methods: Prospective, descriptive, cross-sectional study included 372 patients who applied a survey. Results: 257 patients (69.1%) possessed a good degree of information; 18 (4.8%) regular and 97 (26.1%) bad. The average age was 41 ± 12 years and 58.8% belonged to the socio-economic stratum IV while for those who had good knowledge of Human Papilloma virus (HPV), for the women´s with less information was average age 47 ± 15 years and 64.9% belonged to the socio-economic stratum IV (P = 0,000). Among the patients with higher levels of knowledge, 56.8% had between 26 and 45 years, 58.8% had elementary school approved and 58.8% had previous diagnosis of HPV infection. Among those with a low level of knowledge, 36.1% had between 26 and 45 years, 77.3% had elementary school approved and 19.6 had previous diagnosis of infection. Respect to the information 268 know that is an infection of sexual transmission, 251 knew the condom protects against the infection, 222 associated the infection with the early begin of activity sexual, 261 with the number of sexual couples and 212 with the cancer of neck uterine. Conclusions: A high percentage of patients have a good knowledge HPV genital infection.
RESUMO
Though social influence is a critical factor in the initiation and maintenance of marijuana use, the neural correlates of influence in those who use marijuana are unknown. In this study, marijuana-using young adults (MJ; n = 20) and controls (CON; n = 23) performed a decision-making task in which they made a perceptual choice after viewing the choices of unknown peers via photographs, while they underwent functional magnetic resonance imaging scans. The MJ and CON groups did not show differences in the overall number of choices that agreed with versus opposed group influence, but only the MJ group showed reaction time slowing when deciding against group choices. Longer reaction times were associated with greater activation of frontal regions. The MJ goup, compared to CON, showed significantly greater activation in the caudate when presented with peer information. Across groups, caudate activation was associated with self-reported susceptibility to influence. These findings indicate that young adults who use MJ may exhibit increased effort when confronted with opposing peer influence, as well as exhibit greater responsivity of the caudate to social information. These results not only better define the neural basis of social decisions, but also suggest that marijuana use is associated with exaggerated neural activity during decision making that involves social information.

Previous studies have reported that peer groups are one of the most important predictors of adolescent and young adult marijuana use, and yet the neural correlates of social processing in marijuana users have not yet been studied. In the current study, marijuana-using young adults (n = 20) and non-using controls (n = 22) participated in a neuroimaging social exclusion task called Cyberball, a computerized ball-tossing game in which the participant is excluded from the game after a pre-determined number of ball tosses. Controls, but not marijuana users, demonstrated significant activation in the insula, a region associated with negative emotion, when being excluded from the game. Both groups demonstrated activation of the ventral anterior cingulate cortex (vACC), a region associated with affective monitoring, during peer exclusion. Only the marijuana group showed a correlation between vACC activation and scores on a self-report measure of peer conformity. This study indicates that marijuana users show atypical neural processing of social exclusion, which may be either caused by, or the result of, regular marijuana use.
RESUMO
Though decades of research have shown that people are highly influenced by peers, few studies have directly assessed how the value of social conformity is weighed against other types of costs and benefits. Using an effort-based decision-making paradigm with a novel social influence manipulation, we measured how social influence affected individuals' decisions to allocate effort for monetary rewards during trials with either high or low probability of receiving a reward. We found that information about the effort-allocation of peers modulated participant choices, specifically during conditions of low probability of obtaining a reward. This suggests that peer influence affects effort-based choices to obtain rewards especially under conditions of risk. This study provides evidence that people value social conformity in addition to other costs and benefits when allocating effort, and suggests that neuroeconomic studies that assess trade-offs between effort and reward should consider social environment as a factor that can influence decision-making.

BACKGROUND: Though substance use is often associated with elevated risk-taking in real-world scenarios, many risk-taking tasks in experimental psychology using financial gambles fail to find significant differences between individuals with substance use disorders and healthy controls. We assessed whether participants using marijuana would show a greater propensity for risk-taking in distinct domains including, but not limited to, financial risk-taking. METHODS: In the current study, we assessed risk-taking in young adult (age 18-25) regular marijuana users and in non-using control participants using a domain-specific risk-taking self-report scale (DOSPERT) encompassing five domains of risk-taking (social, financial, recreational, health/safety, and ethical). We also measured behavioral risk-taking using a laboratory monetary risk-taking task. RESULTS: Marijuana users and controls reported significant differences on the social, health/safety, and ethical risk-taking scales, but no differences in the propensity to take recreational or financial risks. Complementing the self-report finding, there were no differences between marijuana users and controls in their performance on the laboratory risk-taking task. CONCLUSIONS: These findings suggest that financial risk-taking may be less sensitive than other domains of risk-taking in assessing differences in risky behavior between those who use marijuana and those who do not. In order to more consistently determine whether increased risk-taking is a factor in substance use, it may be necessary to use both monetary risk-taking tasks and complementary assessments of non-monetary-based risk-taking measures.

PURPOSE: To assess the acceptability and efficacy of training community health workers (promotores) in Mexico to both recognize psychosis and to teach others to recognize psychosis. METHODS: Two studies were carried out utilizing a single-group design. In Study 1, promotores watched a DVD-based psychosis literacy training. In Study 2, promotores were trained to administer a flip-chart version of the program and they then administered it to community residents. RESULTS: Significant increases in the post-training assessment of psychosis literacy were observed. CONCLUSION: Promotores can be an important resource in identifying psychosis early and enhancing the sustainability of psychosis literacy information campaigns.

Adolescents and young adults who affiliate with friends who engage in impulsive behavior are more likely to engage in impulsive behaviors themselves, and those who associate with prosocial (i.e. more prudent, future oriented) peers are more likely to engage in prosocial behavior. However, it is difficult to disentangle the contribution of peer influence vs. peer selection (i.e., whether individuals choose friends with similar traits) when interpreting social behaviors. In this study, we combined a novel social manipulation with a well-validated delay discounting task assessing impulsive behavior to create a social influence delay discounting task, in which participants were exposed to both impulsive (smaller, sooner or SS payment) and non-impulsive (larger, later or LL payment) choices from their peers. Young adults in this sample, nâ=â51, aged 18-25 had a higher rate of SS choices after exposure to impulsive peer influence than after exposure to non-impulsive peer influence. Interestingly, in highly susceptible individuals, the rate of non-impulsive choices did not increase after exposure to non-impulsive influence. There was a positive correlation between self-reported suggestibility and degree of peer influence on SS choices. These results suggest that, in young adults, SS choices appear to be influenced by the choices of same-aged peers, especially for individuals who are highly susceptible to influence.

OBJECTIVE: The objective of the study is to determine the safety of intravenously administered combination sedatives in the emergency department (ED). METHODS: This was a retrospective study of alcohol-intoxicated patients in the ED. We examined the incidence of adverse events in agitated patients who received combination sedatives intravenously and compared the efficacy of combination sedatives and single-agent sedatives. RESULTS: Of 1300 patient visits, there was a single adverse event, a dystonic reaction, in the combination sedative group, for an adverse event rate of less than 1%. Patients who received combination sedatives were less likely to require a second dose of sedative medication than patients who received a single-agent sedative (21% vs 44%). CONCLUSIONS: Combination sedatives appear to be safe when administered intravenously in the ED. Combination sedatives may be more effective than single-agent sedatives in agitated alcohol-intoxicated patients.
