RESUMO
The increasingly popular #fitspiration community on Instagram aims to promote body positivity and inspire health in its followers. However, fitspiration accounts often endorse unattainable, overly fit body ideals. The aim of this study is to explore the effects of viewing fitspiration photos on body image and fit-ideal internalisation. We compared 109 British students' (18-50 years-old) responses on state self-esteem, mood satisfaction, body satisfaction and fit-ideal internalisation before and after viewing fitspiration photos. Online questionnaires exposed students to either five male or five female fitspiration photos, respectively for their given gender. Photos were sourced from public Instagram accounts. This study also examined the influence age and Instagram usage have on body image. Exposure to fitspiration photos produced a significant reduction in state self-esteem, mood satisfaction and fit-ideal internalisation, but had no significant influence on body satisfaction. Age had no effect on body image; however, gender impacted mood satisfaction and fit-ideal internalisation. Instagram usage influenced fit-ideal internalisation, with specific Instagram factors, such as how the importance of a photo's "likes" were negatively associated with state self-esteem, mood and body satisfaction. Unexpectedly, Instagram frequency use and posting were related to higher levels of state self-esteem. Detailed explanations of the findings and potential future research opportunities are also discussed.

OBJECTIVE: To evaluate a minimal dose intervention of six 1-hour sessions of task-oriented circuit gait training including a caregiver over a 12-week period to persons post stroke in the South African public health sector. DESIGN: Stratified, single blinded, randomized controlled trial with three intervention groups. PARTICIPANTS: Persons post stroke ( n = 144, mean age 50 years, 72 women), mean 9.5 weeks post stroke. INTERVENTIONS: Task group ( n = 51)-accompanied by a caregiver; task-oriented circuit gait training (to improve strength, balance, and task performance while standing and walking). Strength group ( n = 45); strength training of lower extremities while sitting and lying. Control group ( n = 48); one 90-minute educational session on stroke management. MEASURES: The six-minute walk test (6MinWT) was the primary outcome; the secondary outcomes included comfortable and fast gait speeds, Berg Balance Scale (BBS), and Timed Up and Go (TUG). Particpants evaluated at baseline, post intervention (12 weeks), and at follow-up 12 weeks later. Change scores were compared using generalized repeated measures analysis of variance (ANOVA). RESULTS: Task group change scores for all outcomes post intervention and at follow-up were improved compared to the other groups ( P-values between 0.000005 and 0.04). The change scores (mean, 1SD) between baseline and follow-up for the Task, Strength, and Control groups, respectively, were as follows: 6MinWT:119.52 m (81.92), 81.05 m (79.53), and 60.99 m (68.38); comfortable speed 0.35 m/s (0.23), 0.24 m/s (0.22), and 0.19 m/s (0.21); BBS: 9.94 (7.72), 6.93 (6.01), and 5.19 (4.80); and TUG: -14.24 seconds (16.86), -6.49 seconds (9.88), and -5.65 seconds (8.10). CONCLUSION: Results support the efficacy of a minimal dose task-oriented circuit training program with caregiver help to enhance locomotor recovery and walking competency in these persons with stroke.

Soil transmitted helminths (STHs) affect more than one billion of the world's population and are very prevalent in regions with high poverty rates and poor sanitation. Efforts to achieve Millennium Development Goals, such as combating diseases and increasing the number of people with access to safe drinking water and proper sanitation facilities, will directly help in eliminating STHs. The Plains regions of Bangladesh has one of the highest prevalence rates of STHs, and the efforts made by the World Health Organization might not be enough to eradicate these diseases in this region before the 2015 goal. This survey was conducted in the Manikganj district of Central Bangladesh to evaluate local awareness about the transmission and prevention of STHs. The results from this survey show that although a large percentage of the respondents were knowledgeable about the spread and impact of intestinal worms, the majority of individuals still do not take the necessary steps to prevent infection. Our findings demonstrate the complexity of controlling and eliminating STHs and show that concluding efforts should incorporate additional measures for vaccine development as well as improved educational efforts that are sensitive to the region's traditions and cultures.

Hp-FAR-1 is a major, secreted antigen of the parasitic nematode Heligmosomoides polygyrus, a laboratory mouse model frequently used to study the cellular mechanisms of chronic helminth infections. The DNA encoding Hp-FAR-1 was recovered by screening a fourth larval (L4) H. polygyrus cDNA expression library using antibodies raised against L4 stage excretory/secretory (E/S) proteins. Predictions of secondary structure based on the Hp-FAR-1 amino acid sequence indicated that an alpha-helix predominates in Hp-FAR-1, possibly with some coiled-coil conformation, with no beta-structure. Fluorescence-based ligand binding analysis confirmed that the recombinant Hp-FAR-1 (rHp-FAR-1) binds the fluorescent fatty acid analog 11-((5-[dimethylaminoaphthalene-1-sulfonyl)amino)undecanoic acid (DAUDA), and by competition oleic acid. RT-PCR amplification of the hp-far-1 gene indicated that the gene is transcribed in all parasitic stages of the organism's life cycle. The presence of a secreted FAR protein in the well-defined laboratory model of H. polygyrus provides an excellent model for the further study and analysis of the in vivo role of secreted FAR proteins in parasitism, and supports the mounting evidence that secreted FAR proteins play a major role in nematode parasitism.
