title: PERCEIVED BARRIERS TO LEISURE-TIME PHYSICAL ACTIVITY IN THE BRAZILIAN POPULATION

description: ABSTRACT The aim of this study was to synthesize and analyze scientific evidence of the perceived barriers to leisure-time physical activity (PA) in the Brazilian population. The Lilacs, SciELO, PubMed, ScienceDirect and Web of Science journal databases were reviewed and the number of reports of each barrier to PA, grouped according to the level of determinants of the social ecological model (intrapersonal, interpersonal and environmental) was analyzed. We found 25 studies (11 in adolescents, 8 in adults and 6 in older adults), totaling 62,678 reports of barriers to PA. The studies were conducted in the South (n=15), Southeast (n=7), and Northeast (n=2) regions, and one study also included different regions of Brazil. Overall, about seven out of every 10 reports on barriers to PA involved intrapersonal barriers. Adults and older adults had a higher proportion of reports of intrapersonal barriers (84.8% and 74%, respectively), than adolescents (47.8%). There are still few studies with older adults, children, and in populations of the Midwest and North of the country. The most frequently reported barriers to PA among adolescents were lack of company, lack of social support from family and friends, unsuitable climate and limited access to spaces for PA. Lack of motivation and lack of time were the most frequently reported barriers in adults, whereas in older adults the predominant barriers were lack of motivation and diagnosed disease or physical limitation. PA promotion programs need to take into account the different barriers to PA, since these are specific to age groups. Level of Evidence II; Systematic Review of Level II Studies.

title: Comparison of optical coherence tomographic findings between Behcet disease patients with and without ocular involvement and healthy subjects

description: ABSTRACT Purpose: We aimed to compare the retinal nerve fiber layer, ganglion cell layer, inner plexiform layer, and the choroid thickness between patients with Behcet disease and healthy subjects by using spectral domain optical coherence tomography (SD-OCT). Methods: Ninety eyes of 45 healthy subjects and 104 eyes of 52 patients with Behcet disease were included in this study. Rheumatoid factor and C-reactive protein levels were measured by blood testing in the patients. Results: The mean thickness of the retinal nerve fiber layer, ganglion cells layer, and inner plexiform layer were significantly lower in patients with Behcet's disease than in the healthy subjects. The mean choroidal thickness was significantly higher in the patients than in the healthy subjects. Conclusions: SD-OCT was a useful and non-invasive tool for the detection of retinal nerve degeneration and choroidal changes in patients with Behcet disease even in the absence of ocular involvement.

title: 2D analysis of laminated composite and sandwich plates using a new fifth-order plate theory

description: Abstract In the present paper, a new fifth-order shear and normal deformation theory (FOSNDT) is developed for the bi-directional bending analysis of laminated composite and sandwich plates subjected to transverse loads. This theory considered the effects of both transverse shear and normal deformations. In-plane displacements use a polynomial shape function expanded up to fifth-order in terms of the thickness coordinate to properly account the effect of transverse shear deformation. Transverse displacement is the function of x, y and z- coordinates to account the effect of transverse normal deformations i.e. thickness stretching. Hence, the present theory involves nine unknowns in the displacement field. The present theory does not require a problem dependent shear correction factor as it satisfies traction free boundary conditions at top and bottom surfaces of the plate. The governing differential equations and associated boundary conditions are obtained using the principle of virtual work. The plate is analysed for simply supported boundary conditions using Navier’s solution technique. To prove the efficiency of the present theory, the non-dimensional displacements and stresses obtained for laminated composite and sandwich plates are compared with existing exact elasticity solutions and other theories. It is observed from the comparision that the displacements and stresses obtained by the present theory are in excellent agreement with the results obtained by exact elasticity solutions compared to other higher-order plate theories available in the literature.

title: Managment of orbital complications of sinusitis

description: Purpose: We reported on the clinical approaches of ophthalmology and otorhinolaryngology departments in the treatment of the orbital complications of sinusitis. We also included an in-depth literature review. Methods: We retrospectively reviewed the medical files of 51 patients from January 2008 to January 2014. The records were evaluated for age, gender, type of orbital complications, symptoms, predisposing factors, imaging studies, medical and surgical management, culture results, and follow-up information. SPSS version 15.0 software (Statistical Analysis, The Statistical Package for Social Sciences Inc, Chicago, IL) was used for the statistical analysis. Results: Fifty-one patients met the criteria, with available medical records, for the study (29 male, 22 female). Thirty-two (62.7%) were diagnosed with preseptal cellulitis and 19 (37.3%) with postseptal cellulitis. After a detailed evaluation, 15 were diagnosed with a subperiosteal abscess (SPA), and 4 were diagnosed with orbital cellulitis. The age and gender was similar for the two groups. Five patients with medial SPA were treated with endoscopic sinus surgery, one patient with inferior SPA was treated with external surgery, and six patients with other localizations were treated with a combination of endoscopic sinus surgery and external surgery. All patients presented with periorbital erythema and edema. The length of hospitalization and duration of symptoms were similar in both groups. Visual acuity was between 1/10 to 10/10 (mean 7/10) and statistically significant for preseptal and postseptal cellulitis groups (p&lt;0.001). All patients received intravenous antibiotics upon the first day of admission. Conclusion: Orbital complications of acute sinusitis required intensive follow-up and a multidisciplinary approach. A contrast-enhanced paranasal sinus computerized tomography (CT) scan can detect the extent of the infection. An initial trial of intravenosus (IV) antibiotics may be appropriate when close monitoring is possible. Surgery may be indicated when there has been no improvement within 48 hours of intravenous treatment, loss of visual acuity (under 8/10), and a non-medial abscess.

title: Pipeline Stress Analysis Through Stress Function Fittings

description: Abstract This work presents a hybrid experimental technique for stress analysis in pipes due to soil-pipe interaction. It was used a variation of Digital Speckle Pattern Interferometry (DSPI) combined with a small indentation setup for acquiring radial displacement points. Data collected are fitted under the Airy stress functions method for the determination of displacements and strain components. The radial displacement data is fitted in to extract Airy stress function coefficients in a short combination selected specifically for the analysis of stress fields in pipes. This technique is of great utility as an auxiliary approach to the actual field data compilation.

title: Evaluation of choroidal thickness in patients with obstructive sleep apnea/hypopnea syndrome

description: Purpose: To compare the subfoveal choroidal thickness (SFCT) of patients with different severities of obstructive sleep apnea/hypopnea syndrome (OSAHS) and normal controls via enhanced depth imaging optical coherence tomography (EDI-OCT). Methods: In this retrospective, case-control study, 49 eyes from 49 patients that had undergone polysomnography were included. SFCT of the horizontal and vertical line scans were manually measured for all eyes based on EDI-OCT images. Two separate analyses were performed according to different apnea/hypopnea index (AHI) groupings. Initial testing was conducted using non-OSAHS, mild OSAHS (5≤AHI&lt;15), moderate OSAHS (15≤AHI&lt;30), and severe OSAHS (AHI≥30) patient groupings, while secondary testing used non-OSAHS, mild OSAHS (5≤AHI&lt;15), and moderate/severe OSAHS (AHI≥15) patient groupings. Results: The mean SFCT was 314.5 μm in the non-OSAHS patients (n=14), 324.5 μm in the mild OSAHS patients (n=15), 269.3 μm in the moderate OSAHS patients (n=11), and 264.3 μm in the severe OSAHS patients (n=9). SFCT between the four groups revealed no significant differences despite a trend towards slight thinning in the severe group (P=0.08). When the moderate and severe groups were merged and compared with the mild OASHS and non-OSAHS groups, SFCT of the moderate/severe group was found to be significantly thinner than that of the mild group (P=0.016). A negative significant correlation was found between SFCT and AHI in OSAHS patients (r=0.368, P=0.033). Conclusions: In patients with moderate/severe OSAHS, EDI-OCT revealed a thinned SFCT. Other accompanying systemic or ocular diseases may induce perfusion and oxygenation deficiency in eyes of OSAHS patients. Further studies are required in order to determine the exact relationships between ocular pathologies and clinical grades of OSAHS.

title: The role of mast cells in vascularized recurrent pterygium

description: Objective: To determine and compare the mast cell count in primary and recurrent vascularized pterygium, and in normal bulbar conjunctiva. Methods: The study included 22 patients with primary pterygium (PP group) and 28 patients with vascularized recurrent pterygium (VRP group) that underwent excision via the limbal conjunctival autograft technique. Normal conjunctiva samples were collected from the superotemporal bulbar conjunctival region, just temporal to the site from which the autograft conjunctival tissue was harvested. The total number of mast cells in the pterygium (primary and recurrent) and control tissue samples was calculated microscopically using 1% toluidine blue stain under 400× magnification. Results: The mean mast cell count in primary and vascularized recurrent pterygium tissue was 7.45 ± 2.06 mm–2 and 16.11 ± 4.33 mm–2, respectively, and the difference was significant (independent samples t-test, P&lt;0.001). The mean mast cell count in pterygium tissue was significantly higher than that in normal conjunctiva tissue in both groups (Student's t-test, P&lt;0.001). Conclusion: An increase in the number of mast cells might play a role in the pathogenesis of recurrent pterygium. Determination of a mast cell count cut-off value could be of diagnostic significance for recurrent pterygium.

title: Influence of head posture on the visual acuity of children with nystagmus

description: Purpose: Evaluate the relationship between the postural alignment of the head and possible interference in the view of children. Methods: We evaluated 11 children between 2 and 7 years of age of both sexes, with the visually impaired, who had nystagmus and head lock position. The test Lea Grating Acuity Test® was used to collect measurements of visual acuity. This applied on two occasions: with and without postural alignment of the head. For reliability of the postural alignment of the head, the slopes were measured by Fisiologic® software. Results: The children had a poorer performance after physiological postural alignment. This poor performance is possible due to loss of position lock nystagmus to gain postural alignment, said to be ideal. Postural compensations were observed, and sharply increased eyestrain. Conclusion: The pursuit of traditional postural alignment affect the visual response of children with visual impairments.

title: Aqueous wheat extract (Triticuma estivum) prevents carboplatin-induced myelosuppression and oxidative stress in Wistar rats

description: ABSTRACT: The present study aimed to evaluate the use of aqueous wheat extracts as an adjunct to antineoplastic therapy with carboplatin. In this study, 32 rats were used which were randomly distributed into 4 groups: G1 - negative control; G2 - control treated with physiological solution; G3 - animals treated with aqueous extract of wheat in the concentration of 100mg/kg; G4 - animals treated with aqueous wheat extract at the concentration of 400mg/kg; 300mg/m² of carboplatin was administered intraperitoneally at day 0 in animals from groups G2, G3, and G4, whereas 1ml of physiological solution was administered by the same route in animals from group G1. Animals were treated daily for 21 days by orogastric gavage according to their respective experimental group. Blood was collected from animals on days 3, 7 and 21 for complete blood count (CBC), biochemistry, and measurement of paraoxonase 1 (PON1) activity. On day 21, animals were euthanized and necropsied. Promising results were obtained regarding oxidative balance in groups G3 and G4. Both presented better PON1 activity in comparison with group G2 (P&lt;0.05). Total leukocyte count of group G4 differed significantly from group G2 (P&lt;0.05) on day 21. Myelogram values of animals from groups G3 and G4 were similar to those from G1; animals from G3 had lower numbers of promyelocytes and increased numbers of erythrocytes and rubriblasts than animals from G2 (P&lt;0.05). In the present experimental study, aqueous wheat extract was safe at the doses used in the animals, and was an effective treatment for myelosuppression and for the prevention of an excessive release of free radicals induced by carboplatin.
