A marcha humana, ou locomoção bípede, pode ser definida como sendo umprocesso contínuo de perda e recuperação o equilíbrio a partir da mudança de posição. Durante a marcha normal, a ativação da musculatura da coluna vertebral e acelerações do tronco resultam em ciclos de cargas aplicadas à coluna. O aumento da velocidade de caminhada aumenta a amplitude de movimento da coluna lombar e os níveis de ativação da musculatura ao redor do tronco. A coordenação postural automática alterada associada com lombalgia pode ser resultado de uma variedade de fatores que vão desde a estratégia de movimento escolhida até a diminuição da força exercida sobre a superfície de apoio, passando por mudanças nos níveis de contração muscular por medo do movimento e/ou dor. O foco atencional do indivíduo, quando dirigido a algum fator externo pode alterar a sua percepção da dor e diminuir as alterações em seus padrões de movimento na marcha. Estudos anteriores mostram que a força de reação do solo apresentou alterações significativas entre grupos de pessoas com e sem dor lombar crônica. O objetivo deste estudo foi analisar a possível influência do foco atencional no equilíbrio dinâmico de pessoas com dor lombar crônica bem como buscar, na marcha de pessoas com dor lombar crônica clinicamente comprovada, diferentes padrões de movimentos sob diferentes focos atencionais. Além disso, pretendeu-se descrever os efeitos dos diferentes focos atencionais sobre o comportamento das variáveis analisadas na marcha em sujeitos com e sem dor lombar crônica. Fizeram parte do grupo analisado 22 sujeitos que foram orientados, primeiramente, a executar três caminhadas que consistam em, ao menos, três ciclos completos da marcha na velocidade preferida, em linha reta, ao longo da pista de caminhada. Diferentes situações de condução do foco atencional foram utilizadas ao longo das caminhadas que se seguiram. A obtenção dos parâmetros cinemáticos angulares tridimensionais da marcha foi executada através de um sistema de análise de movimentos (Vicon Motion Systems) e os dados cinéticos foram obtidos utilizando-se duas plataformas de força modelo OR6-2000, (Advanced Mechanical Technology, Inc.,Watertown, MA, EUA). Todos os dados foram tabulados em planilhas eletrônicas do Microsoft Excel 2003 (Microsoft Corp., EUA). A análise estatística foi realizada no software SPSS 13.0, por meio de Análises de Variância entre as diferentes situações de condução do foco atencional e as variáveis analisadas, com nível de significância de 5%. A ANOVA entre as diferentes situações de condução do foco atencional e as variáveis analisadas não mostrou diferenças significativas entre cada tarefa executada simultaneamente à marcha dos indivíduos (p> 0,9). Conclui-se, a partir dos resultados encontrados, que as diferentes situações de condução do foco atencional utilizadas nesse estudo, apesar de referendadas pela bibliografia utilizada como base teórica, não podem ser usadas de maneira consistente como forma de diminuir os efeitos da dor lombar crônica sobre o comportamento das variáveis analisadas na marcha dos indivíduos avaliados nesse estudo. / The human gait, or bipedal locomotion, can be defined as the continuous process of losing and regaining balance from the change of a geographic location to another. During normal operation, the activation of the muscles of the spine and trunk accelerations result in load cycles applied to the column and increased walking speed increases the range of motion of the lumbar spine and the activation levels of the muscles around the trunk. Changes in the automatic postural coordination associated with low back pain may result from a variety of factors ranging from the motion strategy chosen to decrease the force exerted on the support surface , through changes in levels of muscular contraction for fear of movement and or pain. The attentional focus of the individual, when directed at some external factor, can change your perception of pain and decrease the changes in their patterns of gait movement. Previous studies show that the ground reaction force significantly changed between groups of people with and without chronic low back pain. The present study aimed to analyze the possible influence of attentional focus on dynamic balance of people with chronic low back pain and seek, in the gait of people with chronic low back pain clinically proven, different movement patterns under different attentional foci. In addition, we intend to describe the effects of different attentional focus on the behavior of the variables in gait in subjects with and without chronic low back pain. Formed the group examined 22 subjects who were asked, first, to run three walks consisting of at least three complete cycles of motion in preferred speed, straight along the hiking trail. Different leading situations of attentional focus were used along the walks that followed. The attainment of the three-dimensional angular kinematic parameters of gait was performed using a motion analysis system ( Vicon Motion Systems) and kinetic data were obtained using two force platforms model OR6 - 2000 ( Advanced Mechanical Technology , Inc. Watertown , MA , USA ) . All data were tabulated in spreadsheets Microsoft Excel 2003 ( Microsoft Corp . , USA ) . Statistical analysis was performed with SPSS 13.0, using analysis of variance between the different leading situations of the attentional focus and the other variables, with a significance level of 5 %. The ANOVA between different leading situations of the attentional focus and the other variables showed no significant differences between each task performed simultaneously with the motion of individuals (p > 0.9). It is concluded from the results that the different leading situations of the focus used in this study, although ratified by the bibliography used as a theoretical basis, can’t be used consistently in order to diminish the effects of chronic low back pain about the behavior of the variables in the gait of the subjects in this study.

The aim of this essay is to study how youth utilize social media based on themes such as identity and integrity. The focus has been on young people’s use of Instagram. The study is based on qualitative focus groups to collect empiricism. Interviews have been done with four different groups. Two groups of mixed girls and boys and two groups where one was with girls only and one with only boys. The purpose has been to see if there are similarities and / or differences between how girls and boys look at their use of Instagram. The study also concerns the participants' urge to use social networks based on concepts such as confirmation and motivation. The result of this study shows both differences and similarities between the different focus groups. Social media have a function in how young people create their identity and how the identity is maintained. The study also presents that young people have different types of identities depending on context. A similarity between users is the strategic use they have of Instagram.

O objetivo deste estudo transversal foi a aplicação do enfoque de risco de acordo com a metodologia proposta pela Organização Mundial da Saúde em uma favela com alta mobilização social e organização comunitária, na zona leste do município de São Paulo. Foram identificadas familias (n=458) que possuiam crianças abaixo de cinco anos de idade (n=694), homogeneamente distribuidas entre sexo e faixa etária. A realização de entrevistas com as mães e tomada de medidas antropométricas das crianças permitiram identificar os fatores de risco e a desnutrição proteico-calórica (D.P.C.). A comunidade foi caracterizada em termos dos perfis do meio ambiente, da família, da mãe e da criança. A prevalência encontrada utilizando-se a classificação de Gomez, foi de 70,3 por cento eutróficos, 25,6 por cento desnutridos de I grau; 3,4 por cento desnutridos de II grau; e 0,6 por cento de III grau. Para o diagnóstico da desnutrição optou-se pelo padrão de referência NCHS, adotando-se o percentil 10 como nivel crítico e o indicador para peso/idade ( 19,7 por cento da população total). As 60 variáveis independentes identificadas foram analisadas considerando-se as categorias de \"risco\" e \"não risco\" para desnutrição. Foram selecionadas 17 variáveis estatisticamente associadas por meio do teste x2 (p<0.05) e Odds-Ratio. Os fatores de risco que compuseram a escala foram: água de torneira para beber, presença de chuveiro e de descarga na bacia, tamanho da família, número de cômodos na casa, presença de geladeira e de liquidificador, baixo peso ao nascer, morbidade e tipos de morbidade, diarréia, assistência médica, paridade, estado civil, suplementação alimentar, idade da mãe e pré-natal. Para alguns fatores de risco clássicos, como aleitamento materno, não ficou evidenciada a associação significante nesta comunidade de estudo. As variáveis da categoria risco que estatisticamente estavam associadas à desnutrição foram agrupadas e constituíram Escala de Risco, com faixas estatisticamente definidas, estabelecendo-se pontos de corte nas faixas, com base na validade por meio de modelo de regressão logística. Os achados demonstraram que esta escala é indicada pois foi desenvolvida baseada em dados reais da comunidade, com sensibilidade=85,606060 por cento e especificidade=31,760435 por cento . Concluiu-se que a referida escala pode ser usada pela comunidade e pelos serviços locais de saúde no combate conjunto a desnutrição. / The aim of this transversal study was to apply the nutritional approach, based on the World Health Organization risk approach methodology, on an slum in the east side of São Paulo city. From the slum, a highly organized community, were selected families (n=458) with children under five years old (n=694), with uniform sex and age distribution. The interviews with the mothers and the anthropometry measurements allowed the identification of the risk factors (independent variables) and the protein-energy malnutrition (dependent variable). The community was characterized in terms of environment, family/mother and children profiles. The adoption of Gomez-type nutrition classification presented prevalence of 70.3 per cent standard; 25.6 per cent first degree malnutrition; 3.4 per cent second degree malnutrition and 0.6 per cent third degree malnutrition. The malnutrition diagnosis used the NCHS - National Center for Health Statistics percentiles, adopting the 10th percentile as the critical level and the weight-for-age index (19.7 per cent of the total population). From the 60 independent variables analyzed as \"risk\" and \"no risk\" categories for the malnutrition, 17 were selected through the testing for significance -x2- p<0.05 as well as it was applied the Odds-Ratio to evaluate the strength of the association. The 17 risk factors that composed the risk scale were: drinking water; existing blender and refrigerator; shower and flush; family size; dwelling number of room; birth weight; morbidity and kinds of morbidity; diarrhoea; parity; marital status; medical assistance; nutritional supplementation; mother\'s age; and prenatal. Some classic risk factors, such as breast feeding, didn\' t present significance for the studied community. The risk scale was statistically defined in zones, establishing cut points based on the validity through multiple regression model. The findings showed that this scale is indicated because it was carried out based on actual community data, with sensibility = 85.606060 per cent and specifieity = 31.760435 per cent . In conel usion, is suggested the use of the scale in the community and by the local health services for joint action against the malnutrition.

Class of 2014 Abstract / Specific Aims: The final year of the Doctor of Pharmacy program at the University of Arizona is comprised of seven 6-week Advanced Pharmacy Practice Experiences (APPEs). Students evaluate rotations via voluntary anonymous, web-based assessments at the end of each rotation. The purpose of this study was to evaluate an original and a modified assessment tool using pharmacy student focus groups to determine if student feedback via the assessment tools accurately reflected opinions of rotation content and preceptor performance. Methods: Two moderators conducted tape-recorded focus groups with fourth-year pharmacy students using 10 standardized prompts. The first focus group included 5 students from the class of 2013. Based on data from that session, the assessment tool was modified. The second focus group included 5 students from the class of 2014 to evaluate the outcome of these modifications. Session transcripts and notes were used to construct thematic analysis tables and draw conclusions. Main Results: Focus group data revealed feedback via both assessment tools was not completely honest because of concerns about anonymity. The Class of 2013 felt limited by evaluating only their primary preceptor. The Class of 2014 stated that some revisions to the evaluation tool, such as item-specific comment boxes and separate evaluative sections for rotation site, preceptor, and rotation experience were helpful; however, they found the assessment tool lengthy, leading to survey fatigue. Conclusion: Student feedback from either assessment tool was not completely reflective of true attitudes of rotation experiences. Continued improvements to the tool and its delivery may provide more accurate feedback for quality improvement purposes.

Class of 2016 Abstract / Objectives: To identify stakeholder concerns regarding a potential requirement that all prescriptions include the reason for use or indication. Methods: This was a mixed methods study that employed focus groups. Participants were invited by the Chief Executive Officer (CEO) of the Arizona Pharmacy Association (AzPA) to attend focus groups via webinar. E-mail invites were sent to AzPA members and members of Arizona healthcare professional associations with prescriptive authority except for prescribers who care for animals. The discussion began with a PowerPoint presentation and then questions were presented to guide discussion. Afterwards, questionnaires were distributed through e-mail. Interval level data were analyzed using means and standard deviations. The commentary of the focus group discussion was summarized in themes. Results: Preliminary findings, from two focus groups with a total of seven participants, reflected the following concerns with the inclusion of the indication on prescriptions: compromise of patient privacy; technology capabilities; prescriber time; prescriber compliance; and prior authorization complications. The proposed benefits were: enhanced communication; better medication counseling; reduced prescribing errors; decreased controlled substance diversion; and increased accuracy of a prospective drug use review by pharmacists for patients with complicated disease states. Conclusions: In conclusion, stakeholders were concerned with the implementation of including the indication on prescription orders.

Magister Artium (Psychology) - MA(Psych) / The effects of risky sexual behaviour (RSB) amongst adolescents are devastating in South Africa. Recent studies show that parent-child (PC) communication about RSB is associated with positive outcomes such as delayed sexual debut and increased autonomy among adolescents. There are however challenges on how to define caregivers within the South African context due the historical background of South Africa such as Apartheid and labour migration. For the purposes of this study, caregivers would be regarded as individuals who the have sole responsibility of caring for a child. The aim of this study was to explore caregiver-child communication in relation to RSB to gain an in-depth and contextualized understanding of how South African families interact, feel and experience their communication and the challenges they face, it therefore uses a qualitative approach. These aims translate into the following objectives a) exploring the process of communication i.e. how they communicate in terms of style, content, timing and frequency b) exploring the experiences of communication of RSB for both caregivers and children in terms of their thoughts and feelings as well as the challenges faced. Conducting focus group discussions and individual interviews was the method of data collection. Four focus groups (two focus groups with male adolescents and two focus groups with female adolescents) were conducted as well as three individual interviews with caregivers a total of 23 participants were used. Both groups of participants are of mixed racial backgrounds and from the Northern sub district of Cape Town. The data was analyzed by using thematic analysis. All ethical principles were adhered to. This study found mothers to be an influential source of sexual communication with their children and this communication hinged more on the health risks of early sexual debut and negative social outcomes. Caregivers highlight the barriers to communication with their adolescents which create caregiver anxiety and avoidance of sexual communication. School has also been identified as highly influential to both caregivers and adolescents especially with regards to the biological and physiological aspects of sex education. Two types ‘educational systems’ have been identified within the South African context. The impact of these systems on the quality of education and nature of the resources provided to both caregivers and learners are discussed in relation to sexual education and communication. The community and extended family of the participants are very involved in the socialisation of the adolescents in this study and often assist caregivers. Caregiver monitoring is the most utilized strategy used to ensure that adolescent whereabouts and activities are known at all times. Possible interventions such as additional strategies for caregivers to consider and communication workshops for caregivers and educators are discussed. The limitations of this study such as the limited amount of caregivers interviewed and the lack of male caregiver insight were identified and recommendations for future studies are provided.

The objective of the present study was to; 1) determine if the use of a continuous cognitive task demonstrates distinct characteristics of a more automatic control of posture, compared to an external focus (EF) and feet together (FT) postural task, and to 2) examine which condition, if any, exhibits the characteristics of increased ankle stiffness proposed by Winter et al. (1998), as well as displaying increased ankle muscular co-contractions, which are a suggested neuromuscular mechanism that stiffens posture. Fifteen young adults stood on a force platform and performed 4 separate conditions: FT, EF, single number sequence (SNS), and double number sequence (DNS). Throughout the session, surface electromyography (EMG) signals were collected from the tibialis anterior (TA) and medial gastrocnemius (MG) of each leg. Each testing session consisted of 24 trials, with 6 per condition. Results displayed decreased sway area for SNS and DNS compared to FT. Sway variability in the anterior/posterior (AP) direction SNS and DNS were smaller compared to EF and FT. As well sway variability in the medial/lateral (ML) direction was smaller for SNS and DNS compared to FT. ML Mean velocity (MV) did not differ across conditions, though in the AP direction it was larger for SNS and DNS compared to EF and FT. AP Mean power frequency (MPF) was larger for SNS compared to FT. In the ML direction MPF was larger for SNS and DNS compared to FT. Co-Contraction indices revealed no differences across conditions. Conversely the left TA for DNS revealed increased EMG activation compared to EF and SNS.
