title: Criteria for identification of Schistosoma mansoni eggs in faecal sediments prepared with the Helmintex method and stained by ninhydrin

description: Helmintex is a sensitive method used for detecting Schistosoma mansoni eggs. Here, we describe the observed frequency of six proposed criteria associated with the identification of S. mansoni eggs prepared with the Helmintex method and stained with ninhydrin. The efficacy of these criteria in classifying S. mansoni eggs when applied in various combinations was also examined. Nine observers registered the presence or absence of 6 different criteria in 100 eggs using a microscope at 100x magnification. Ninhydrin purple, which was frequently observed, was the criterion associated with the lowest inter-observer variability. At least three criteria were associated with a significantly better performance in egg identification. In conclusion, ninhydrin staining and a combination of criteria are recommended for microscope examination of faecal sediments.

title: Assessment of stormwater runoff in pavement of soil-cement blocks

description: ABSTRACT In this article, the authors assessed the runoff coefficient C (drained volume/volume precipitate), which defines the capacity reduction of runoff, of a pavement with soil-cement interlocking blocks (20.7 m long and 3 m wide) within a structure of transverse concrete beams deployed in an area with slope of 6% and low permeability soil, and similar conditions in areas occupied by poor populations. One hundred and eighty-four events (rainfall) were recorded, but only events with a precipitate volume greater than the maximum capacity storage of pavement (≈ 1,500 liters) and a temperature less than 23ºC, to maintain the accuracy of the measurement sensor, were considered. The experimental values of the coefficient C varied in the range of 0.47 to 0.79, confirming that the soil-cement block pavement is semi permeable.

title: Long-term treatment with 3,4-methylenedioxymethamphetamine caused retina damage in C57BL/6 mice

description: ABSTRACT Purpose: As a class of psychostimulant drugs, amphetamines are widely abused for their stimulant, euphoric, and hallucinogenic properties. Many of these effects result from acute increases in dopamine and serotonin neurotransmission. Following the onset of these effects, 3,4 methylenedioxymethamphetamine produces persistent damage to dopamine and serotonin nerve terminals, resulting in long-lasting neurotoxicity. The purpose of this investigation was to assess the effects of treatment with low dose of methylenedioxymethamphetamine on retinal function of C57BL/6 mice and its underlying mechanisms. Methods: C57BL/6 mice were divided randomly into two groups (n=10): one group was treated with phosphate buffered saline by intraperitoneal injection daily; the other group was treated with 1 mg/kg methylenedioxymethamphetamine by intraperitoneal injection daily for three months. Electroretinography was used to test retinal function every month. H&E staining and terminal deoxynucleotidyl transferase assay were used to evaluate the retinal morphology and histology. Enzyme-linked immunosorbent assay assays were used to measure markers of oxidative stress and inflammatory factors. Gene and protein expression was detected by real-time PCR and western blot. Results: Three-month treatment with methylenedioxymethamphetamine induced significant retinal dysfunction via photoreceptor cell apoptosis by oxidative stress and inflammatory responses. Conclusions: These results suggest that long-term treatment with methylenedioxymethamphetamine increases inflammatory responses in photoreceptor cells resulting in retinal dysfunction in C57BL/6 mice. Thus, this investigation provides preclinical rationale for the retina damage caused by the methylenedioxymethamphetamine abuse.

title: Feeding effects of cottonseed and its co-products on the meat proteome from ram lambs

description: ABSTRACT: Gossypol easily pairs with lysine side chains and enzymes involved in the cellular growth process. The effect of gossypol (a compound present in cotton co-products) in ruminant metabolism and meat quality is not yet clear. This study was undertaken in order to evaluate the effects of cotton co-products in lamb muscle proteome. Twenty-four Santa Inês ram lambs, 5-months old (20.6 ± 1.9 kg), were randomly assigned to four treatments: control (without cottonseed), whole cottonseed, cottonseed meal and high oil cottonseed meal. At 95 days into the experiment, lambs were slaughtered and samples from Longissimus dorsi were collected. Proteins were extracted and analyzed by 2-D electrophoresis. Spots showing a significant effect from the treatment (the “treatment effect”) and present in more than 90 % of the samples were identified using mass spectrometry. Cotton co-products decreased the abundance of aldehyde and malate dehydrogenases, creatine kinase M-type and Adenosine triphosphate (ATP) synthase. They also increased four proteins related to muscle contraction. Thus, feeding cotton co-products to lambs changed the abundance of important muscle proteins. A cotton co-product diet induced a negative impact on the energy supply of muscle cells and, consequently, the abundance of ATP dependent proteins (contractile apparatus) increased, probably in order to offset and maintain muscle function. These proteomic changes can promote our understanding of alterations in the sensorial properties of meat due to cotton co-product diets in further investigations.

title: Conscious capitalism: a netnographic analysis in groups of the social network Linkedin

description: Abstract The concept of conscious capitalism structured by John Mackey and Raj Sisodia, is based on the principles of higher purpose, stakeholder integration, conscious leadership, and conscious culture and management, understanding that capitalism can be a force for the economy, social welfare, and for the environment. In this context, the objective of the study was to identify and analyze the content posted and the interactions carried out in discussions about conscious capitalism in groups of the social network Linkedin. The research an exploratory and descriptive study, adopting a qualitative approach and netnographic procedures observing groups on Linkedin. The study used a model of simplified flow of a netnographic research project by Kozinets (2010). The main results indicate that: most of the group owners are in the United States, where conscious capitalism was born; the groups were created with the purpose of interacting with themes related to conscious capitalism; the interactions in the groups happen mainly through posts and comments with subjects related to conscious capitalism. However, the number of members of a group does not reflect a higher number of interactions. Finally, most groups understand conscious capitalism according to the definition set by the pioneers, John Mackey and Raj Sisodia, but putting it into practice in organizations has been a challenge.

title: ARTHROSCOPIC TREATMENT FOR LATERAL EPICONDYLITIS: OUTCOMES IN 104 CASES OF A SINGLE INSTITUTION

description: ABSTRACT Objective: To evaluate the outcomes of patients that underwent arthroscopic surgery for lateral epicondylitis (LE), after failed conservative treatment. Methods: One hundred four patients with LE treated with arthroscopic debridement of the extensor carpi radialis brevis (ECRB) tendon were enrolled in this retrospective study. They were evaluated using Disabilities of the Arm, Shoulder and Hand (DASH) score, Visual Analogue Scale (VAS) and Short Form Health Survey (SF-36) scale. Mean age at surgery was 46.9 years. Duration of symptoms was 2.1 years (range: 6 m to 10 yrs.). Mean follow-up was 34.4 months (range: 6 to 68 m). Results: Mean postoperative scores were: 20.67 points on the DASH; 1.8 points on the VAS at rest, with 48 cases (46%) without pain, 40 (38%) with mild pain, 13 (13%) with moderate pain and 4 (4%) with severe pain; 4.7 points on the VAS in activity, with 21 (20%) without pain, 21 (20%) with mild pain, 35 (34%) with moderate pain and 27 (26%) with severe pain; and SF-36 was 66.8 points. Of the 23 patients who practiced sports regularly or with higher physical demand from the upper limbs, 17 (74%) were able to return to the same activity at the same level. No significant complications were observed postoperatively, except for 3 (2.8%) cases of postoperative superficial infection. Conclusion: Surgical treatment with arthroscopy for recalcitrant LE is effective and safe, presenting positive outcomes in the studied patients. Level of evidence IV, Case Series.

title: INACTIVE BEHAVIOR IN ADOLESCENT STUDENTS OF THE BRAZILIAN WESTERN AMAZON

description: ABSTRACT Objective: To identify the prevalence of physical inactivity in adolescent students in the city of Porto Velho, RO, Northern Brazil, and its associated factors. Methods: School-based study, conducted with 2,694 adolescents. The self-reported variable for outcome was physical inactivity. Factors associated with inactive behavior were verified by multiple logistic regression. The independent variables were inserted into the model in hierarchical blocks. Results: The overall prevalence of inactive behavior was 39.5%. Females showed a higher prevalence of physical inactivity (46.2%) than males (31.4%). Adolescents in private schools and with reports of negative health perception had a high prevalence of physical inactivity. Regarding associated factors, the female sex showed a magnitude of association of 1.84 with physical inactivity. Being in a private school was associated with a 2.54 times greater chance of physical inactivity compared to public school students. Going to school by bus, car or motorcycle was associated with a 1.29 and 1.63 higher chance of physical inactivity respectively. Adolescents who reported having a negative health perception had 1.29 higher chance of physical inactivity, while having excess body fat showed magnitude of association of 1.36 in adolescents. Conclusions: There was a high prevalence of physical inactivity in the studied adolescents. Considering that the behavior of physical inactivity adopted during adolescence may continue in adulthood, the promotion of actions that can change this behavior may improve health in the future as well as quality of life.

title: Sutureless transconjunctival intrascleral intraocular lens fixation: the modified Yamane technique

description: ABSTRACT Purpose: To evaluate the efficacy and safety of the modified Yamane technique with sutureless transconjunctival intrascleral intraocular lens fixation. Methods: Sutureless transconjunctival intrascleral haptic fixated intraocular lens implantation was performed in patients with aphakia and dislocated intraocular lenses. A clear corneal incision (2.8 mm) was made into the temporal quadrant and a three-piece intraocular lens was implanted into the anterior chamber. The haptics of the intraocular lens were externalized with a 27 G needle via transconjunctival scleral tunnels at the 6 and 12 o’clock positions. The transconjunctival scleral tunnels were prepared to conform to the haptic position and curvature. The site of the scleral tunnels was 2mm from the limbus with a length of 2 mm in the sclera and was aimed at the end of the posterior chamber. The tips of the haptics were cauterized to create a terminal knob. The haptics were pushed back and the knobs were implanted into the scleral tunnels. Results: The study cohort included 21 patients with unilateral aphakia and dislocated intraocular lenses. All patients were examined postoperatively and at postoperative day 1, day 7, month 1, and month 3. All examinations revealed formation of the anterior chamber and well-centralized intraocular lenses. No haptic-related complications of exposure, foreign body sensation, or discomfort were observed. Conclusion: Sutureless transconjunctival intrascleral haptic fixated intraocular lensimplantation is an effective, safe, and practical surgical alternative. This technique was superior to the Yamane method with regard to comfort and surgical duration. Further studies with longer follow-up evaluations are warranted to verify long-term complications.

title: PRIMARY LEIOMYOSARCOMA OF BONE: CLINICOPATHOLOGIC AND PROGNOSTIC FACTORS ANALYSIS IN A SINGLE INSTITUTION

description: ABSTRACT Objective: Primary leiomyosarcoma of bone (PLB) is a rare type of malignant bone tumor considered as a variant of the spindle cell sarcomas (SCS). The objective of this study was to analyze the clinicopathologic and the prognostic factors of patients with PLB treated at a single institution. Methods: We retrospectively reviewed the records of 22 patients with pathologically confirmed PLB. The data collected were: age, sex, tumor size and location, grade and stage of the disease and histopathologic features. Mean age was 45.5 years (range, 17 to 73 y). Location was: upper limb (27.3%), lower limb (68.2%) and pelvis (4.5%). Patients had high grade in 90.9% of the reports. Margins were negative in 77.3% of the cases. Histological reports describe spindly sarcomatous cells arranged in fascicles with increased vascular formation without osteoid or chondroid matrix production. On immunohistochemistry, smooth muscle actin and desmin where positive in all cases. Results: Mean follow-up time was 73.5 months (range, 5.3 to 331.1 m). We found 22.7% of local recurrence (LR). Distant metastasis (DM) was reported in 9 (40.9%) patients. Lung metastasis was the only DM affected site. Overall survival (OS) rate in 5 years was 59.1%. Predictors of OS were LR and DM. Conclusions: PLB is an extremely rare malignant bone tumor that has a higher rate of DM and similar OS prognosis compared with other bone sarcomas. Level of Evidence IV, Case Series.
