A batata-doce é um alimento, que possui uma grande variabilidade genética, no qual pode ser selecionadas para algumas finalidades como, por exemplo: maior resistência a pragas e doenças. Pesquisadores da Universidade Federal do Tocantins -UFT- vem realizando desde 1997, estudos com batata-doce, destinada a produção de etanol. Desde então vem sendo realizados melhoramento genético entre genótipos com o intuito de melhorar a produção do biocombustível. Entretanto, existem genótipos com características desejáveis ao consumo humano. Diante disso, o objetivo deste trabalho foi avaliar alguns desses genótipos, com intuito de encontrar características adequadas para mesa. As análises realizadas foram: formato, resistência a insetos, cor de casca e cor de polpa. Foram avaliadas 30 cultivares, nas quais duas morreram. As cultivares HSF 0506 e BDI 2011-52 apresentaram bom formato de raiz (nota 1). As cultivares BDI 2011-52 (nota 1,11) e HSF 0506 (nota 1,33) se destacaram com melhores notas em resistência a insetos. A cor predominante de casca e polpa foi branca (64%) e creme (71%), respectivamente. Segundo os dados avaliados, conclui-se que a cultivar HSF 0506 se mostrou superior às outras, atendendo os padrões de mesa solicitados pelo consumidor.

Objetivou-se avaliar os efeitos da aplicação do pó de rocha fosfatada como substrato na produção de mudas de Paricá (Shizolobium amazonicum). O experimento foi desenvolvido no viveiro Florestal da Universidade Federal do Tocantins, campus de Gurupi, sendo conduzido em delineamento inteiramente casualizado, constituído por 5 tratamentos: T1: 0% de pó de rocha (PDR) + 100% de Substrato comercial; T2: 25% de PDR + 75% de Substrato comercial; T3: 50% de PDR + 50% de Substrato comercial; T4: 75% de PDR + 25% de Substrato comercial; T5: 100% de PDR + 0% de Substrato comercial), com 4 repetições, onde em cada repetição foram avaliadas as médias de 10 plântulas. Foram observados os efeitos da adição do pó de rocha ao substrato comercial no desenvolvimento da espécie Shizolobium amazonicum. As mudas de Shizolobium amazonicum produzidas com baixas proporções de pó de rocha ao substrato comercial tiveram uma boa resposta (Efeito positivo) no seu desenvolvimento. Portanto recomenda-se utilização de uma mistura de 25% PDR + 75% substrato comercial, elevando os níveis minerais do substrato, pois esse tratamento permitiu melhor desempenho germinativo, mostrando-se mais adequados para a produção eficaz de mudas da espécie.

Background:
For almost 30 years, bone-anchored prostheses have offered an alternative solution to prosthetic sockets by attaching the artificial limb directly to the femoral residuum by means of an osseointegration implant. Osseointegration implant surgery was introduced in our center in 2009. The aim of the present study is to report on safety, prosthesis-wearing time, and health-related quality-of-life (HRQoL) for patients with femoral bone-anchored prostheses during a 5-year follow-up period.

Methods:
All patients who underwent implantation of a press-fit osseointegration implant between May 2009 and November 2013 were eligible for the present study. Implantation was performed in 2 stages. Adverse events included infectious complications (grade 1 to 4), aseptic loosening, breakage, stoma-redundant tissue, and stoma hypergranulation. Prosthesis-wearing time and HRQoL were measured with the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA) prosthetic use score and global score, respectively.

Results:
Thirty-nine of 42 eligible patients were included. Thirty patients (77%) presented with some kind of infection (156 events in total), with 148 (95%) events being classified as grade 1 or 2 and 8 events (5%) being classified as grade 3; the latter 8 events occurred in 4 patients. There were no instances of septic loosening. The intramedullary stem of the osseointegration implant broke in 2 patients. In total, soft-tissue refashioning had to be done 30 times in 14 patients. The Q-TFA median prosthetic use and global scores improved significantly from 71 to 100 and from 33 to 75, respectively (p < 0.001).

Conclusions:
Despite the adverse events, patient prosthetic use and HRQoL improved significantly. Grade-1 and 2 infections were frequent but could mostly be treated with nonoperative measures. Most infections seemed to occur in the first 2 years and did not lead to deep infections. Two broken intramedullary stems were revised successfully. Current developments focus on reduction of infectious complications and prevention of osseointegration implant breakage.

Published: April 2020

Case:A 59-year-old man was struck by an automobile resulting in left anterior column posterior hemitransverse acetabular fracture with ureteral entrapment. Open reduction internal fixation was performed with removal of the ureter from the fracture. At follow-up 7 months post-op, the patient did not report significant hip or urinary symptoms, and implant position and fracture alignment remained intact.Conclusion:Surgeons should be mindful of possible ureteral injury associated with acetabular fractures. Awareness of this rare entrapment within medially displaced acetabular fractures may heighten clinical suspicion and improve management.

Abstract
Background Evidence is needed regarding effective incentive strategies to increase clinician survey response rates. Within a larger clinical trial of population-based BRCA1/2 mutation screening, we conducted a randomized controlled study comparing the use of upfront cash cards requiring email activation versus checks as clinician survey incentives.Methods We mailed paper surveys to 500 primary care providers (PCPs) in New York, Boston, Los Angeles and Philadelphia who were nominated by study participants to disclose BRCA1/2 mutation results obtained through the study. The first 303 clinicians were randomized to receive the $50 incentive as a cash card (N = 155) or check (N = 148). We compared response rates by incentive type, adjusting for PCP characteristics and study site.Results In unadjusted analyses, PCPs who received checks versus cash cards were more likely to respond to the survey (54.1% versus 41.9%, p = 0.046); this remained true when we adjusted for provider characteristics (OR for checks 1.61, 95% CI 1.01, 2.59). No other clinician characteristics had a statistically significant association with response rates in adjusted analyses. When we included an interaction term for incentive type and city, the favorable impact of checks on response rates was evident only in Los Angeles and Philadelphia.Conclusions An upfront cash card incentive requiring email activation may be less effective in eliciting clinician responses than up-front checks. However, the benefit of checks for clinician response rates may depend on clinicians’ geographic location.

Abstract
Background Patient safety in hospitals is being jeopardized, as too many patients experience adverse events. Most of the adverse events arise from human factors, such as inefficient teamwork and communication failures, and the incidence of adverse events is greatest in the surgical area. Previous research has shown the effect of team training on patient safety culture and on different areas of teamwork. Limited research has investigated teamwork in surgical wards. The aim of the study was to evaluate the outcome of a team training intervention among healthcare professionals in a surgical ward after 6 and 12 months. The Systems Engineering Initiative for Patient Safety 2.0 was used as a conceptual framework for the study.Methods This study had a pre-post design with measurements at baseline, after 6 months and 12 months of intervention. The intervention was conducted in a urology and gastrointestinal surgery ward in Norway, and study site was selected based on the leaders’ willingness to participate in the project. Survey data from healthcare professionals, measured by the TeamSTEPPS Teamwork Perceptions Questionnaire, the Collaboration and Satisfaction about Care Decisions in Teams, and the unit-based sections of the Hospital Survey of Patient Safety Culture Questionnaire, were used to evaluate the intervention. A paired t-test, a Wilcoxon signed-rank test, a generalized linear mixed model and linear regression analysis were used to analyze the data.Results After six months, improvements were found in organizational outcomes in two patient safety dimensions. After 12 months improvements were found in both organizational and professional outcomes, that was in three patient safety culture dimensions and three teamwork dimensions. The generalized linear mixed model estimates demonstrated that physicians had effect on two patient safety culture measures. Furthermore, results showed that teamwork was associated with the organizational outcome Patient Safety Grade.Conclusion These results demonstrate that the team training program had an effect after 12 months of implementation. Future studies are recommended to examine the causal effect of a team training intervention in this context, preferably with studies with larger sample sizes and stronger study designs.Trial registration number:ISRCTN13997367 (retrospectively registered)

Abstract
Background An ongoing global pandemic of pneumonia caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused thousands of deaths in China since December, 2019. We aimed to describe the clinical course of patients died of SARS-CoV-2 infection.Methods In this retrospective study, we reviewed 194 patients with SARS-CoV-2 infection, who died consecutively between Feb 3 to 24, 2020 in Tongji Hospital (Wuhan, China). Basic demographic and clinical information, laboratory findings, complications and treatments were extracted from electronic medical records of Hospital Information System. Unpaired t test was employed to evaluate the statistical differences of the serum level of high-sensitive cardiac troponin I (hs-cTnI) among different age or sex groups. The relationship between hs-cTnI and inflammatory cytokines were estimated using Spearman correlation analysis.Results The death patients aged 69.62 ± 10.98, in which 68.6% were male. 74.7% patients had underlying chronic illnesses. The most common symptoms were fever (83%), cough (69.3%), and dyspnea (65.6%). Decreased lymphocyte count (91.4%), elevated level of hs-cTnI (82.9%) and inflammatory parameters in serum were commonly seen. The hs-cTnI level was significantly higher in the group aged 60–79 and male patients. A week positive correlation was observed between hs-cTnI values and D-dimer values (r = 0.343, p༜0.05). Acute respiratory distress syndrome was the main complication. Assisted respiration, antimicrobial drugs, glucocorticoids and immune globulin were the major treatments.Conclusion Most non-survivors with SARS-CoV-2 infection were old with chronic illnesses, complicated by multiple organ dysfunction. Prevention is better than cure in high-risk population.

Abstract
Background Many surveys today use a web-survey as an alternative to more traditional survey modes. Yet, web-surveys targeting older individuals are still uncommon for various reasons. However, with younger cohorts approaching older age, the potentials for web-surveys among older people might be improved. In this study, we investigated response patterns in a web-survey targeting older adults and the potential importance of offering a paper questionnaire as an alternative to the web questionnaire.Methods We analyzed data from three waves of a web-based retirement study, in which a paper questionnaire was offered as an alternative to the web questionnaire in the last reminder. We mapped the response patterns, compared web- and paper respondents and compared different key outcomes resulting from the sample with and without the paper respondents, both at baseline and after two follow-ups.Results Paper-respondents were more likely to be women, low educated, fully retired, non-married and reported higher depression and lower self-rated health, compared with web-respondents. The association between retirement status and depression was only present among web-respondents. The differences between web and paper respondents were stronger in the longitudinal sample (after two follow-ups) than at baseline.Conclusions We conclude that a web survey might be a feasible and good alternative in surveys targeting people in the retirement age range. However, without offering a paper questionnaire, a small but important group will likely be missing with potential biased estimates as the result.

Abstract

Background: Ethiopia’s maternal mortality rate is among the highest in the world with 470 deaths per 100,000 live births. Every year post-partum hemorrhage (PPH) remains the leading cause of maternal mortality in Ethiopia. The problem is worse in the rural setting where there are not proper facilities and trained health workers to administer injectable medicine. Currently, the methods used by health centers in rural areas include referring the patient to the nearest hospital within a short period of time even though most of patients die in the ambulances without reaching the hospitals in nearby. Method: In this project, the design of rotary-wing unmanned aerial vehicle (UAV) with thermoelectric cold-box system is proposed. The temperature of blood bag is controlled by a thermoelectric cooler working based on the Pieter effect. The blood is transported to rural health centers through UAV, and the blood containing box will release it from higher altitudes using servo dropping mechanism. Results: The prototype was built and undergone through different iteration process. The proposed device was tested for safety, delivery time, bioavailability, range of operation, weight of the package and durability. For this design, the drone was flown a distance of 10km with less than 15 minutes while 100 meters above the ground. Conclusion: The proposed project has a clinical significance such as saving the lives of mothers and the child. Through the design of a UAV, the transportation of medical and biological component is feasible. The use of UAVs for medical supply delivery will considerably reduce the number of people admitting to the hospital and, therefore, minimizes the cost of medical services that comes with hospitalization.

Abstract
Background: Predicting survival of recipients after liver transplantation is regarded as one of the most important challenges in contemporary medicine. Hence, improving on current prediction models is of great interest. Nowadays, there is a strong discussion in the medical field about machine learning (ML) and whether it has greater potential than traditional regression models when dealing with complex data. Criticism to ML is related to unsuitable performance measures and lack of interpretability which is important for clinicians. Methods: In this paper, ML techniques such as random forests and neural networks are applied to large data of 62294 patients from the United States with 97 predictors selected on clinical/statistical grounds, over more than 600, to predict survival from transplantation. Of particular interest is also the identification of potential risk factors. A comparison is performed between 3 different Cox models (with all variables, backward selection and LASSO) and 3 machine learning techniques: a random survival forest and 2 partial logistic artificial neural networks (PLANNs). For PLANNs, novel extensions to their original specification are tested. Emphasis is given on the advantages and pitfalls of each method and on the interpretability of the ML techniques. Results: Well-established predictive measures are employed from the survival field (C-index, Brier score and Integrated Brier Score) and the strongest prognostic factors are identified for each model. Clinical endpoint is overall graft-survival defined as the time between transplantation and the date of graft-failure or death. The random survival forest shows slightly better predictive performance than Cox models based on the C-index. Neural networks show better performance than both Cox models and random survival forest based on the Integrated Brier Score at 10 years. Conclusion: In this work, it is shown that machine learning techniques can be a useful tool for both prediction and interpretation in the survival context. From the ML techniques examined here, PLANN with 1 hidden layer predicts survival probabilities the most accurately, being as calibrated as the Cox model with all variables.

Abstract
Background Preserving the health of health care workers (HCWs) has now become one of the main concerns of all countries affected by the coronavirus. Maintaining the health of the hospital workers, especially the medical staff, requires knowledge and awareness, followed by proper behavior for disease prevention and transmission. The purpose of this study was to evaluate the knowledge, attitude and behavior of HCWs to ward patients with suspected or confirmed COVID-19.Methods A cross-sectional study was designed to assess the level of knowledge, attitude and behavior of 191 HCWs of Taleghani Hospital in Kermanshah toward patients with suspected or confirmed COVID-19. Responses to the checklists of demographic characteristics, knowledge, attitude, and behavior toward patients with COVID-19 were analyzed by SPSS 22.Results 191 subjects (118 females and 73 males) with a mean age of 34.7 ± 8.6 years participated in this study. The level of knowledge of HCWs in this study was excellent regarding the ways of transmitting the disease such as close contact with the patient with suspected Coronavirus (99%). According to their positions, participants had a significant difference in their knowledge of asymptomatic patients (P < 0.001). The study found that 14% of the HCWs did not have the necessary knowledge about the symptoms of COVID-19, indicating poor knowledge of the HCWs at the beginning of the disease epidemic. The results obtained from the evaluation of HCWs attitudes showed that some workers believed that protective and preventive measures should only be applied when managing people with severe symptoms (P < 0.001). Finally, there was a significant difference in behavior and adherence to protective and preventive measures between the participants when facing patients with severe symptoms and without symptoms of COVID-19 (P = 0.05).Conclusion Knowledge, attitude, and behavior toward COVID-19 infection and facing patients with severe and overt symptoms among health care workers in the hospital were Excellent, but these were insufficient for patients without obvious symptoms. These results suggest that additional training regarding subclinical cases of Coronavirus is needed for HCWs to protect them from contamination and prevent disease transmission to their colleagues and other patients as well.
