title: The door is open, but not everyone may enter: racial inequities in healthcare access across three Brazilian surveys

description: Abstract Health policies in Brazil have sought to expand healthcare access and mitigate inequities, but recent revisions of their content have weakened the Brazilian Unified Health System. This study estimates three healthcare indicators across three national surveys conducted in 2008, 2013, and 2019 to assess the impact of changes to the National Primary Care Policy on racial inequities in healthcare. Considering the survey design and sampling weights, we estimated the prevalence of each outcome among both whites and Blacks for the whole country, and according to the Brazilian regions. We test the following hypotheses: compared to whites, Blacks showed higher frequency of coverage by the Family Health Strategy, lower frequency of health insurance coverage, and higher frequency of perceived difficulty accessing health services (H1); Racial inequities decreased in the ten-year period but remained constant between 2013-2019 (H2); Racial gaps have widened among regions with lower proportions of Blacks (H3). Our findings fully support H1, but not H2 and H3. Racial inequities either remained constant or decreased in the 2013-2019 period. By downplaying the importance of the universality and equity principles, the latest revision of the National Primary Care Policy has contributed to the persistence of racial inequities in healthcare.

title: Smartphone as a tool for evaluating oblique muscle dysfunction

description: ABSTRACT Purpose: The aim of this study was to describe a simple, accessible, and reliable method using a smartphone for evaluating oblique muscle dysfunctions. Methods: The photograph rotation tool in the iPhone PHOTO app was used by 75 examiners to evaluate 22 photographs from only 9 patients, captured in infra- and supra-dextroversion, and infra- and supra-levoversion, as not all the patients were photographed in the 4 positions mentioned. Each patient received a score for the superior and inferior oblique muscle functions, ranging from -4 (hypofunction) to 4 (hyperfunction) or 0 (normal function), using preediting and postediting photographs. These values were compared with the scores previously given by trained personnel in strabismus screening. The difference in score between the two groups was expressed in natural (whole and non-negative) numbers. The mean and pattern deviation were then calculated. Results: The scores of most of the edited photos showed a lower mean than those of the unedited ones, except for a patient with left superior oblique hyperfunction. The patients with no oblique dysfunction and those with right superior oblique hyperfunction demonstrated (after editing the photograph) scores with greater similarity with their initial scores (p&lt;0.05 and p&lt;0.01, respectively). Similar results were found in the patients with oblique hypofunctions and right inferior oblique hyperfunction (p&lt;0.01). Conclusion: The proposed method for assessing muscular function in vertical strabismus is reproducible, accessible, simple, and reliable, and provides better consistency to the admeasurement.

title: EVALUATION OF THE RANGE OF MOTION OF A HIP ARTHROPLASTY SYSTEM: A COMPUTER SIMULATION STUDY

description: ABSTRACT Objective: To date, the literature lacks consensus on the most efficient method to measure the range of motion of an in vitro prosthetic system. In this study, we propose the use of a relatively low-cost online software to measure the range of motion of hip prosthetic implants manufactured in Brazil and compare its results with the current technical standards for hip arthroplasty. Methods: Three different diameters of femoral heads were evaluated (28 mm, 32 mm, and 36 mm). The mean values of the angular displacement of the prosthesis in each motion axis were obtained by computer simulations. Results: The range of motion with each femoral head was 28mm (extension/flexion: 148°, internal/external rotation: 179°, adduction/abduction: 107°), 32 mm (152°/185°/114°), and 36 mm (158°/193°/120°). Conclusion: The computational method showed that the larger the femoral head, the greater the range of motion of the hip joint prosthetic system. Additional clinical studies are necessary to compare the physical results obtained with the values found in this study by computational modeling. Level of evidence V, Experimental study.

title: Simultaneous ocular and osseous syphilis: a case report

description: ABSTRACT Syphilis is a reemerging and potentially serious disease. Owing to its ubiquity and pleomorphism, it is called “the great imitator”. We report the case of a young woman with secondary syphilis who presented with bilateral acute syphilitic posterior placoid chorioretinopathy along with a syphilitic skull periostitis. A pachymeningeal enhancement was observed on magnetic resonance imaging, but we believe it was an extension of the bone process rather than a meningitis itself on the basis of the normal cerebrospinal fluid analysis results. Treatment with intravenous crystalline penicillin resulted in complete resolution of the signs, symptoms, and imaging findings. Secondary syphilis is the stage with the highest bacteremia and the highest transmissibility, presenting mainly with mucocutaneous disorders and, less frequently, with involvement of other organs. High suspicion and a pragmatic approach are essential to the diagnosis because this disease can affect several organs, as in the present case, in which the eyes, bones, and skin were affected.

title: Does nutritional status moderate the association between social support, self-efficacy, and physical activity time of adolescents?

description: Abstract The scope of this paper is to analyze the association between social support, self-efficacy and practice time of physical activity of different intensity (light, moderate, vigorous) and evaluate if these associations are moderated by the nutritional status of adolescents. It involved a cross-sectional study with 650 adolescents (10-14 years old, 52.9% female) from João Pessoa, State of Paraíba. Social support was measured by a scale with five items for each source of support (father, mother and friends) and self-efficacy, with a scale of four items. The physical activity time was measured by means of an accelerometer and the nutritional status was assessed by body mass index. The results of the multiple linear regression analysis showed that social support of friends was positively and significantly associated with moderate intensity physical activity time (β=2.67; CI95%: 0.28; 5.07). The nutritional status did not moderate the association of social support and self-efficacy with the duration of physical activity (p&gt;0.05). The conclusion drawn is that adolescents who perceived that they are receiving more social support from friends tend to practice more moderate intensity physical activity, irrespective of their nutritional status.

title: The effect of ellagic acid on the repair process of periodontal defects related to experimental periodontitis in rats

description: Abstract Objective This study aims to evaluate the effect of ellagic acid (EA) by measuring the levels of alveolar bone resorption and inflammatory and oxidative stress markers in the periodontal tissues and serum on the periodontal repair process related to experimental periodontitis in rats. Methodology Forty Wistar rats were divided into four study groups as follows: Group 1=healthy control (n=10); Group 2=EA control (15 mg/kg)(n=10); Group 3=periodontitis (n=10); Group 4=periodontitis+EA (15 mg/kg) (n=10). The periodontitis model was established by ligating bilateral mandibular first molars for 14 days. Then, rats were given normal saline or EA for another 14 days by gavage administration. Serum and gingiva myeloperoxidase (MPO) activity, 8-hydroxydeoxyguanosine(8-OHdG), and glutathione (GSH) levels were analyzed by ELISA. İmmunohistochemical analysis was used to detect Interleukin (IL)-6, IL-10, and tumor necrosis factor-alpha (TNF-α) immunoreactivities in the periodontal tissues. Alveolar bone loss (ABL) and attachment loss (AL) was evaluated by histomorphometry analysis. Results ABL and AL were statistically higher in group 3 than in groups 1, 2 and 4 and in group 4 than in groups 1 and 2 (p&lt;0.05). MPO activities in gingival tissue and serum were significantly increased in group 3 compared to groups 1 and 2 (p&lt;0.05). Significantly higher serum GSH levels, lower gingiva, and serum 8-OHdG levels, and MPO activity were observed in group 4 compared to group 3 (p&lt;0.05). Rats with periodontitis (group 3) expressed significantly higher immunoreactivities of IL-6 and TNF-α and lower IL-10 immunoreactivity compared to those other groups (p&lt;0.05). IL-6 and TNF-α immunoreactivities significantly decreased and IL-10 immunoreactivity increased in group 4 after the use of EA compared to group 3 (p&lt;0.001). Conclusions Our findings showed that EA provides significant improvements on gingival oxidative stress and inflammatory markers and alveolar bone resorption in the repair process associated with experimental periodontitis. Therefore, EA may have a therapeutic potential on periodontitis.

title: FROM GARRINCHA’S LEGS TO NEYMAR’S LEGS: THE GENU VARUM AND VALGUM IN SOCCER. HISTORICAL OVERVIEW AND UPDATE

description: ABSTRACT The presence of abnormalities in knee alignment (genu varum and genu valgum) is extremely common in soccer. It can occur in the junior league / youth academy and perpetuate itself throughout the professional career. The consequences of years of high-level sports practice in players with genu varum / genu valgum can be harmful to the knees. By observing football matches of the present and the past, the authors of the article noted that great Brazilian soccer players were, or are, affected by the malalignment of the knees: Garrincha (the most famous), Leandro, Dunga, Romário, Rivaldo and Neymar. This study aims to discuss the relationship between high-performance sport and the development of these orthopedic deformities, serving as a tool for updating the trauma-orthopedic knee subspecialty. Level of Evidence III, Retrospective comparative study.

title: Comparative analysis of biofilm formation by Candida albicans and Candida krusei in different types of contact lenses

description: ABSTRACT Objective: To evaluate the Candida krusei and Candida albicans biofilm formation abilities on 5 different types of contact lenses and compare their metabolic activities and biomass. Methods: After biofilm formation by both the test species, their metabolic activity was assessed by the 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide reduction assay with menadione, while the biomass was determined by staining with 0.4% crystal violet dye for further statistical analysis. Results: Both the Candida species could form biofilms on different types of contact lenses, with greater metabolic activities and lower biomass formation in rigid gas permeable lenses. Conclusion: Biofilm formation with greater metabolic activity and greater biomass were expected on soft contact lenses considering their surface hydrophobicity. However, the results demonstrated a greater metabolic activity on rigid contact lenses. This result has a great significance with regards to the increasing risk of microbial keratitis, although further studies are warranted to better elucidate the formation of biofilms on different types of contact lens materials in the future.
