Biomechanical and organizational risk and prevalence of low back pain in the old adults caregivers of a nursing home in Joao Pessoa/PB

The objective present study was to investigate the presence of low back pain in caregivers of a nursing home, related with the labored activities executed by these workers. 16 subjects were investigated, 15 female and one male, with 40,8 age average all being caregivers as their profession. It consisted of three phases, where the first concerns the analysis of the collective work, assessed in a perspective of caregivers, Second, a postural assessment to verify the retractions in such workers and the third stage was used Diagram of Corllet to identify the presence of signs and symptoms in caregivers. The study demonstrated that organizational and biomechanical factors are responsible for the high level of physical fatigue and presence of pain in 93,75% of the caregivers in some region of the body. 50% referred pain in the lumbar region. The results of the postural evaluation confirmed that the caregivers had alterations in the postural alignment, presenting retractions of the anterior and posterior chain. The suggestions are to minimize the risk factors of this productive process and the symptoms and signals presented from these workers by adoption ergonomic measures and the realization of a physical program with stretching and muscular strengthening of the muscles of the anterior and posterior body chain based on the method of Reorganization Postural Sensoperceptive.     

An ergonomic study on the biomechanical consequences in children, generated by the use of computers at school

This research deals with the influence of the computer use in schools related to the children posture, in an ergonomic point of view. The research tries to identify probable causes for the children early postural constraints, relating it to the sedentary behavior and the lack of an ergonomic project in schools. The survey involved 186 children, between 8 and 12 years old, students of a private school in Rio de Janeiro-Brasil. An historical and theoretical school furniture research was conducted as well as a survey with the students and teachers, computer postural evaluation, ergonomic evaluation (RULA method), and observations in the computer classroom. The research dealt with the student's perception with respect to the furniture utilized by him in the classroom during the use of the computer, his body complaint, the time he spent working on the school computer and the possibility of the existence of sedentariness. Also deals with the teachers' perception and knowledge regarding ergonomics with reference to schoolroom furniture and its Regulatory Norms (RN). The purpose of the research work is to highlight the importance of this knowledge, having in view the possibility of the teachers' collaboration in the ergonomic adaptation of the classroom environment and in their conscientious opinion during the purchasing of this furniture. A questionnaire was utilized and its results showed some discontent on the part of the teachers with relation to the schoolroom furniture as well as the teachers' scant knowledge of Ergonomics.We conclude with a survey that despite the children had constraints in postural assessments and school furniture needs a major ergonomic action, the time that children use the computer at school is small compared with the time of use at home and therefore insufficient to be the main cause of quantified commitments, thus the study of computer use at home as a development and continuity of this research.     

Barriers to Prevention: Ethnic and Gender Differences in Latino Adolescent Motivations for Engaging in Risky Behaviors

Using a sample from the Longitudinal Study of Adolescent health (Add health), we tested whether psychosocial motivation or health factors were the best predictors of sexual engagement by Latinos. The Latino sample (3,460) included sub samples of Mexican (n = 1587) Chicano (n = 137), Cuban (n = 501), Puerto Rican (n = 586), Central/South American (n = 367) adolescents and individuals self-identified as Hispanic other (n = 282). Our findings showed that most Latino adolescents understood that if they had unprotected sex they were at risk for HIV/AIDS and STI’s. Additionally, as we hypothesized, the motivation items were better predictors of sexual engagement than the health risk items. However, the motivation items were only significant for the females with one exception, the Mexican males. There were other subgroup differences as well. Our findings have important implications for prevention strategies.     

Winning a Race: Narratives of Healing and Psychotherapy in Children and Adolescents Who Have Been Sexually Abused

This article explores the process of recovering from sexual abuse according to children and adolescents who have been sexually abused and have successfully completed psychotherapy. In this qualitative study, interviews were conducted with 20 participants from 8 to 18 years of age and then subject to narrative analysis. Results show that participants’ narratives of recovery involve an improvement of psychological well-being. Moreover, they feel better equipped to overcome future challenges, feeling empowered and able to retake control of their lives. Factors that support and inhibit recovery are examined, as are developmental differences. Discussion underlines the valuable role of psychotherapy in helping children and adolescents in their healing process, changing the meaning of the abusive experience, and developing new capacities.     

Training effects on motor–cognitive dual-task performance in older adults

This systematic review investigated whether healthy older adults benefit from training interventions in motor–cognitive dual-task (DT) situations and which specific aspects of the intervention and/or task selection contribute to training benefits. Training effects were analysed with regard to the training programme (e.g., general ST or DT training) and task conditions (e.g., standing or walking, complexity of secondary cognitive task). Literature was searched via OVIDsp (Medline, EMBASE, PsycINFO). DT studies were included by the following criteria: (1) investigation of at least one motor task, (2) assessment of DT performance outcomes on standing or walking, (3) conduction of an intervention, and (4) investigation of older adults in an experimental–control group design or an old–young comparison. Thirteen studies met all inclusion criteria. Four types of interventions were identified: (1) general single-task (ST) motor training, (2) specific ST motor training, (3) general DT training, and (4) task-related (specific) DT training. For DT standing conditions only DT interventions improved motor performance, whereas DT walking also benefits by ST training. Most benefits on motor and cognitive performance seem to be reached by DT training interventions whereas a GST produced lowest effects. Thus, balance orientated motor and cognitive DT performance in healthy older adults can be improved by performance related exercises. Furthermore, to reach beneficial effects, it seems necessary that the training intervention includes a certain level of exercise load such as rising difficulties, appropriate intensity and duration, a certain level of task specificity, and variable task prioritization. The transfer of training effects into everyday situations needs to be further investigated.     

“It's a Different Condom,Let's See How It Works”: Young Men's Reactions to and Experiences of Female Condom Use During an Intervention Trial in South Africa

Although male partner cooperation is often essential for successful use of the female condom, only a few studies have directly assessed men's experiences of using the device. We examined barriers to and facilitators of female condom use via qualitative in-depth interviews with 38 young men (18 to 28 years) in South Africa whose partners, all university students, were enrolled in a female condom intervention trial. In all, 21 men used the female condom; the remaining 17 did not attempt use. The main facilitators to female condom use were convenience of use for men, curiosity to see how female condoms compared to male condoms, enhanced sexual sensation, and perceptions of better safety and comfort of the device compared to male condoms. The main barriers were men's limited familiarity with the device, insertion difficulties, and men's concerns about loss of control over sexual encounters. We recommend that human immunodeficiency virus (HIV) prevention and condom promotion programs around the world target men directly for education on female condoms and that they also work with couples jointly around issues of safer-sex communication and negotiation.     

Does Where I Live Affect Whether I Apply? The Contextual Determinants of Applying for Deferred Action for Childhood Arrivals

The Deferred Action for Childhood Arrivals (DACA) program provides temporary relief from deportation and legal work authorization for eligible undocumented youth in the United States. This study investigates the factors that help or hinder undocumented youth in applying for DACA. We focus on contexts of reception to understand the determinants of DACA applications, as studies of previous legalization programs indicate that the communities in which immigrants live help shape application decisions. Our analysis shows that more immigrant‐serving organizations in a state translate into more applications, that DACA implementation rates are not statistically significantly lower in states with hostile policy climates, and that socioeconomic factors are most significantly related to DACA applications. In identifying the collective factors that influence applying to DACA, we demonstrate that the structural opportunities and barriers present in receiving locales shape undocumented youths’ decisions to regularize their immigration status, which has significant implications for their resulting incorporation trajectories.

Observing Erotic Videos With Heterosexual Content Induces Different Cerebral Responses in Homosexual and Heterosexual Men

ABSTRACT

To determine the cerebral functionality associated with the perception and processing of erotic stimuli in men with different sexual orientation, this work evaluated the electroencephalographic activity (EEG) from several cortical areas, as well as subjective arousal in homosexual and heterosexual men during observation of an erotic film with heterosexual content. The heterosexual men rated the erotic video with higher general and sexual arousal than the homosexual participants. During observation of the neutral and erotic videos, both groups showed a decreased amplitude of the alpha band in prefrontal and parietal cortices, indicating increased attention. When watching the erotic video, the homosexual men showed an increased amplitude of the theta and fast bands only in the prefrontal cortex, which could be related to the cognitive processing of the erotic stimulus. These EEG results should broaden our knowledge of the cortical mechanisms related to the different perception and processing of erotic stimuli in men with different sexual orientations.
