Este trabalho foi premiado no 13° Seminário de Iniciação Científica da UFT, e objetiva monitorar água e tecidos de peixe utilizando um eletrodo de baixo custo (usando pilha descartada) e técnicas voltamétricas para detecção de cobre. As análises foram desenvolvidas no LABMADE (Laboratório de pesquisa em Materiais para Aplicações em Dispositivos Eletrônicos) localizado na Universidade Federal do Tocantins/Araguaína, por meio de um Potenciostato/Galvanostato. A presença de altos índices de metais na água não significa necessariamente que haverá danos aos organismos vivos, mas certamente indicam um estado de contaminação latente poderá levar a toxicidade. Nesse contexto, torna-se necessário monitorar os parâmetros de qualidade aquática e dos seres que o habitam.

As feiras livres são ambientes com características populares que comercializam produtos de origem vegetal e animal, na maioria dos casos sem controle do serviço de vigilância sanitária local. Os alimentos ficam expostos ao ar livre em condições adversas, em contato com possíveis contaminantes. O Brasil apresenta uma grande variedade de rios navegáveis, estes por sua vez são grandes produtores de pescado. O peixe e seus derivados são altamente consumidas pela população. No entanto o pescado quando armazenado de forma incorreta pode ser um potencial transmissor de DTA (Doenças transmitidas por alimentos). Já que sua deterioração pode ser acelerada. O objetivo deste trabalho é avaliar as condições higiênico-sanitárias da comercialização de pescado nas feiras livres de Palmas-TO. Na realização dessa pesquisa foi analisado e aplicado chek list e a avaliação dos aspectos sanitários foi realizada através de roteiro baseado na RDC nº 216 da ANVISA (Agência Nacional de Vigilância Sanitária). Os resultados obtidos no trabalho demonstram problemas na maioria dos boxes de venda do pescado, em equipamentos, utensílios, local de armazenamento e higiene dos manipuladores. Diante disso é possível concluir que a venda de pescado em feiras de Palmas não atendem as condições mínimas de boas práticas de manipulação e higienização, o que pode colocar em risco a saúde dos consumidores, sendo considerado um problema grave de saúde pública.

A raiva é considerada uma zoonose de grande importância por ser uma enfermidade infecciosa caracterizada por encefalomielite fatal causada pelo vírus da família Rhabdoviridae. A principal forma de prevenção é a vacinação dos animais. Em humanos, quando há ocorrência de ataques por animais suspeitos de estarem acometidos pela enfermidade, é feita a vacinação pós-exposição. Este presente trabalho teve como objetivo avaliar fichas de atendimento antirrábico humano pós-exposição no município de Araguaína, no período de 2010 a 2012. Foram analisadas as fichas de todas pessoas que procuraram tratamento após terem sofrido algum tipo de acidente e que pudesse oferecer risco de contração da enfermidade. No período do estudo, foram notificados 1756 atendimentos por agravo com animais e administradas cerca de 1730 doses de vacina. Foram encontrados dados significativos em relação aos fatores estudados, sendo os homens mais frequentemente acometidos quando comparado com as mulheres. Referente à faixa etária, houve diferença estatística significativa quando comparado os adultos em relação aos idosos, sendo os adultos os mais acometidos. Os resultados comprovaram que existe muita demanda deste tipo de atendimento no município. Apesar do grande número de agravos não houve, neste período, cães, gatos ou seres humanos diagnosticados com raiva no município.

Background:
Numerous surgical techniques have been described for the repair of complete distal biceps tendon ruptures. However, the outcome of repair with cortical button fixation has not been extensively evaluated. The hypothesis of the present study was that elbow strength and range of motion would be less than normal after repair but that ongoing disability would be minimal as measured with use of the Disabilities of the Arm, Shoulder and Hand (DASH) score.

Methods:
We performed a retrospective cohort study of patients with complete distal biceps tendon rupture that was repaired with cortical button fixation via a 1-incision anterior approach. Outcome was assessed on the basis of elbow range-of-motion and strength measurements, DASH scores, and radiographs of the operatively treated elbow. Descriptive statistics were generated for patient demographics and outcome variables. Strength was assessed with limb-symmetry index, and range of motion was evaluated with paired t tests.

Results:
Sixty male patients consented to this study. The average age at the time of follow-up was 49.6 ± 7.8 years, and the average time from injury to follow-up was 3.7 ± 1.7 years. The mechanism of injury included lifting heavy objects (62%) and sporting activities (25%). Elbow flexion and supination range of motion were not different between the operatively treated and contralateral arms. The operatively treated elbow demonstrated decreased flexion strength (96% of that on the contralateral side) and supination strength (91% of that on the contralateral side). The findings did not change when controlling for hand dominance. The mean DASH score was 7.9 ± 11.4, which is not significantly different from the normative value for the general population. Postoperative complications included heterotopic ossification (Brooker class I [29 patients] or II [5 patients]), neurapraxia (7 patients), and rerupture (3 patients).

Conclusions:
The repair of complete distal biceps tendon ruptures with cortical button fixation was associated with decreased strength in elbow flexion and forearm supination compared with the contralateral arm, although the differences were small and likely were not clinically important. The complication rate was relatively high; however, most complications were minor and were associated with minimal disability, as reflected by the DASH scores.

» Hoffa fractures are intra-articular distal femoral condylar fractures commonly arising from high-energy trauma with the knee in a flexed position.» Motor vehicle accidents and falls from a height are the most commonly cited mechanisms that engage the lateral or the medial condyle, depending on the internal or external rotation of the knee.» Standard weight-bearing after screw fixation should be delayed for approximately 12 weeks.» Most of the literature found on Hoffa fractures placed more focus on the surgical approach or fixation method rather than outcomes associated with the number or type of screws used.

Published: August 2019

Abstract
Background: We aimed to establish the value of Time-resolved contrast-enhanced magnetic resonance angiography (TR-MRA) in identifying thrombosis of transverse sinus(TS) in patients with a unilaterally absent TS signal on MRV.
Methods: Forty-five patients who were suspected of TS thrombosis clinically with a unilaterally absent TS signal on phase contrast(PC) MRV, were evaluated with TR-MRA. Images obtained by each technique were assessed independently by two neuroradiologists for whether the absent signal was thrombosis or atretic TS. The final diagnosis given based on clinical data and all radiological images(including the asymmetry of the sigmoid notches and TR-MRA) by a consultant neurologist was set as the gold standard and then, the accuracy of radiological diagnosis were validated by observing the agreement with it. The image quality comparison between PC MRV and TR-MRA via calculating signal-to-noise ratios [SNRs] and contrast-to-noise ratios [CNRs] of the normal TS.
Results: For imaging quality of normal TS, the mean SNR and CNR of TR-MRA were 452.14 and 440.92 respectively, significantly higher than the values of PC MRV (both p<0.001). The interobserver agreement of TR-MRA in identifying TS thrombosis from atretic TS was excellent [κ =0.951; 95% confidence interval (CI) 0.902-1.000], much higher than MRV (κ = 0.526; 95% CI, 0.389–0.663). Consensus of assessment based on TR-MRA was highly consistent with the gold standard (sensitivity of 100%, specificity of 93.75%) , superior to PC MRV (sensitivity of 75%, specificity of 81.8%).
Conclusion: TR-MRA is better than PC MRV in the visualization of TS, and helpful to distinguish thrombosis from congenitally atretic TS.

Abstract
Abstract
Background: To investigate the alimentary tract Buckyball injuries in Chinese pediatric patients, and describe the managements and precautionary measures through multicenter investigation.
Methods: Medical records of 74 pediatric patients from 9 large Chinese third-grade class-A hospitals were included in this study. Questionnaires were distributed online, and medical records were reviewed. Follow-ups were through telephone and outpatient service.
Results: Among the 74 cases were 50 boys (68%) and 24 girls (32%). The age was 36.00 (21.75, 77.00) months, range from 7 months to 11 years old, and it showed two peaks, between one and three years old, and from six to eleven years old. The annual case numbers showed sharp increase, and Hebei Province had the largest number of 23 cases. Only 3 of them had exact reasons for swallowing the balls, the rest 71 patients had no intension for the ingestion. From onset to the emergency department time was 2.00 (1.00, 5.25) days, varied from 4 hours to 40 days. Twenty-one patients had no symptoms, and abdominal pain, vomiting, fever, abdominal distension, fiercely crying, melena, and flatus and defecation stopped were in 40 (54.05%), 36 (48.65%), 11 (14.86%), 3 (4.05%), 3 (4.05%), 2 (2.70%), 1 (1.35%) cases. Gastroscope, coloscope, laparoscopic operation, and laparotomy operation were adopted. Gastrointestinal perforation, ischemia and necrosis of gastrointestinal wall, abscess, ileus, fistula was found in 38 (51.53%), 14 (18.92%), 7 (9.46%), 6 (8.11%), 2 (2.70%), other 28 (37.84%) patients had gastrointestinal mucosa erosion. The numbers of Buckyball ingested was 4 (2, 8), with a range from 1 to 39. During the follow-up period of 6 (1, 15) months, three patients had ileus, and one suffered a second operation. The remaining 71 patients were uneventful. None of the 74 patients reported a second time swallowing of Buckyballs or other magnetic foreign bodies.
Conclusions: Pediatric alimentary tract magnetic foreign body ingestion in China is still increasing. Treatments and managements are of great significance, while prevention is more important and time critical. Precautionary measures toward the issue should be taken from three levels.

Abstract
Abstracts

Background

Depth of invasion (DOI) could be calculated by MRI preoperatively, whether MRI-determined DOI could predict the prognosis and whether it could be used as an indicator for neck dissection for cT1N0 tongue squamous cell carcinoma (SCC) remain unknown, the main goal of the current study aimed to answer the questions.

Methods

Patients with surgically treated cT1N0 tongue SCC were retrospectively enrolled, MRI-determined DOI was measured based on T1-weigthed layers by a 1.5T scan. A multivariate logistic regression analysis model was used to determine the independent predictors for occult neck lymph node metastasis. The main study endpoints were locoregional control survival (LRC) and disease specific survival (DSS), the Cox model was used to determine the independent prognostic factors for the LRC and DSS.

Results

Occult neck lymph node metastasis was noted in 26 (17.2%) patients, ROC curve indicated the optimal cutoff value of MRI-determined DOI was 7.5mm for predicting neck lymph node metastasis with sensitivity of 86.9%. The factors of lymphovascular invasion, MRI-determined DOI, pathologic DOI, and pathologic tumor grade were significantly associated with the presence of neck lymph node metastasis in univariate analysis, further logistic regression analysis confirmed the independence of lymphovascular invasion, MRI-determined DOI, and pathologic DOI in predicting the neck lymph node metastasis. The 5-year LRC and DSS rates were 84% and 90%, respectively. Cox model analysis suggested the MRI-determined DOI was an independent prognostic factor for both the LRC and DSS.

Conclusions

Elective neck dissection is suggested if MRI-determined DOI is greater than 7.5mm in cT1N0 tongue SCC, and MRI-determined DOI ≥7.5mm indicates more risk for disease recurrence and cancer caused death.

Published: August 2019

Abstract
Background Allostatic load (AL) is a preclinical marker of the pathophysiologic processes that precede the onset of disease. The goal of this study was to examine the association between racially-motivated housing discrimination and AL score within a sample of Indigenous university students.Methods Data for this cross-sectional study were collected from Indigenous adults attending university in a small city in western Canada between 2015 and 2017 ( N = 104; Mean age = 27.8 years). An item adapted from the Experience of Discrimination Scale was to assess racially-motivated housing discrimination in the past 12 months. AL was measured as a composite of 7 biomarkers assessing neuroendocrine, cardiovascular, metabolic, and immune system function. Bias-corrected and accelerated bootstrapped linear regression models were used to examine associations adjusting for age, income, parenthood, and other situations in which discrimination had been experienced.Results Indigenous university students who experienced racially-motivated housing discrimination in the past year (16.8% of the sample) had an average AL score of approximately 4, which was almost double that of their peers who had not. In an adjusted model. racially-motivated housing discrimination was associated with a-1.5 point increase in AL score. This model explained 35% of the adjusted variance in AL score, of which racially-motivated housing discrimination explained 24% ( R 2 Change = 0.24, F Change = 32.52, Sig. F Change p <0.001).Conclusions Indigenous adults who experienced racially-motivated housing discrimination in the past year had early and more pronounced wear and tear on neuroendocrine, cardiovascular, metabolic, and immune system functioning in young and middle adulthood than Indigenous peers who did not. These findings combine with others to highlight the need for increased efforts to prevent racially-motivated housing discrimination in urban centres.

Abstract
Introduction : In low-resource settings, most maternal deaths caused by hemorrhage, occur in poorly resourced facilities or outside of health facilities where there is no access to skilled obstetric care. Community distribution of misoprostol is one of the compelling strategies for preventing or treating postpartum hemorrhage to avert maternal deaths. This scoping review was conducted to synthesize existing evidence that shows the negative impact of community distribution of misoprostol on facility delivery and misuse for labor induction or pregnancy termination.
Methods: We identified and included all peer-reviewed articles on misoprostol implementation from PubMed, Cochrane Review Library, Popline, and Google Scholars. Narrative synthesis was used to analyze and interpret the findings in which quantitative and qualitative syntheses are integrated.
Results: Three qualitative studies, six observational studies, and four experimental or quasi-experimental studies from Africa and Asia are included in this study. All before-after household surveys reported, increased delivery coverage after the intervention: ranging from 4 to 46 percentage points at the end of the intervention when compared to the baseline (5 studies). The pooled analysis of experimental and quasi-experimental involving 7,564 women from four of the studies revealed that there is no significant difference in facility delivery among the misoprostol and control groups [OR 1.011; 95% CI: 0.906-1.129]. A qualitative study among professionals also indicated that community distribution of misoprostol for the prevention of postpartum hemorrhage is acceptable to community members and stakeholders and it is a feasible interim solution until access to facility birth is improved.
In the community-based distribution of misoprostol programs, administration of misoprostol before delivery was reported in less than 2% among seven studies involving 11,108 mothers. Evidence also shows that most women used misoprostol pills as instructed. No adverse outcomes from misuse in either of the studies reviewed.
Conclusions: The claim that community-based distribution of misoprostol would divert institutional delivery strategies to home deliveries and promote misuse are not supported with evidence. Therefore, community-based distribution of misoprostol can be an appropriate strategy for reducing maternal deaths which occur due to postpartum hemorrhages especially in resource-limited settings where many deliveries take place outside of health facilities.

Abstract
Background Synthesis of psychometric properties of substance use measures to identify patterns of use and substance use disorders remains limited. To address this gap, we sought to systematically evaluate the psychometric properties of measures to detect substance use and misuse. Methods We conducted a systematic review and meta-analysis of literature on measures of substance classes associated with HIV risk (heroin, methamphetamine, cocaine, ecstasy, alcohol) that were published in English before June 2016 that reported at least one of the following psychometric outcomes of interest: internal consistency (alpha), test-retest/inter-rater reliability (kappa), sensitivity, specificity, positive predictive value, and negative predictive value. We used meta-analytic techniques to generate pooled summary estimates for these outcomes using random effects and hierarchical logistic regression models. Results Findings across 387 paper revealed that overall, 65% of pooled estimates for alpha were in the range of fair-to-excellent; 44% of estimates for kappa were in the range of fair-to-excellent. In addition, 69%, 97%, 37% and 96% of pooled estimates for sensitivity, specificity, positive predictive value, and negative predictive value, respectively, were in the range of moderate-to-excellent. Conclusion We conclude that many substance use measures had pooled summary estimates that were at the fair/moderate-to-excellent range across different psychometric outcomes. Most scales were conducted in English, within the United States, highlighting the need to test and validate these measures in more diverse settings. Additionally, the majority of studies had high risk of bias, indicating a need for more studies with higher methodological quality.

Abstract
Objective Previous studies showed that flight muscles were degenerated after migration in some aphid species; however, the underlying molecular mechanism remains virtually unknown. In this study, using the wheat aphid, Sitobion avenae , we aim to investigate aphid flight muscle degeneration and the underlying molecular mechanism.Results Wheat aphid starts to differentiate winged or wingless lines at the second instar nymph, determined at the third instar, and then fully developed at the fourth instar. After migration, the flight muscles degenerated via programmed cell death, which is evidenced by a Terminal deoxynucleotidyl transferase dUTP-biotin nick end labeling assay. Then, we identified a list of differentially expressed genes before and after tethered flights using differential-display reverse transcription-PCR. One of the differentially expressed gene, ubiquitin-ribosomal S27a, was confirmed using qPCR. Ubiquitin-ribosomal S27a is drastically up regulated following aphids’ migration and before the flight muscle degeneration. Our data suggested that aphid flight muscles degenerate after migration, during which endogenous proteins may be degraded to reallocate energy for reproduction.
