Psychophysiological correlates of the disposition effect
We assess the psychophysiological characteristics underlying the disposition effect and find that subjects showing greater disposition effect are those who sweat more and present lower body temperature and heart rate
ROTAÇÃO DE CULTURAS E PREPARO DO SOLO SOBRE O BANCO DE SEMENTES DE PLANTAS DANINHAS EM TERRAS BAIXAS
On the rice crop, weed species more adapted to the production system appear in greater incidence in the area, thus, crop rotation can be an alternative to help reduce the weed seed bank. In this sense, the objective of this work was to evaluate the dynamics of the barnyardgrass (Echinochloa spp.) and alexandergrass (Urochloa plantaginea) seed banks in lowlands, in response to crop rotation and soil management. Rice, soybean and sorghum crops were used under conventional tillage and no-till system, cultivated in strips. Barnyardgrass and alexandergrass seed banks were evaluated after two years of cultivation, in the top 0-5 and 5-10 cm layers of soil. Barnyardgrass and alexandergrass seed bank densities were higher in continuous sorghum cultivation compared to rice cultivation. There was no difference of the seed bank between different soil layers, except for alexandergrassin continuous sorghum cultivation. The continuous sorghum cultivation in lowlands, without the use of a post-emergence herbicide, increases barnyardgrass and alexandergrassseed bank.No monocultivo de arroz, as espécies daninhas mais adaptadas a este sistema de produção aparecem em maior incidência na área. A rotação de culturas pode ser uma alternativa para auxiliar na redução do banco de sementes de plantas daninhas. Nesse sentido o objetivo do trabalho foi avaliar a dinâmica do banco de sementes de capim-arroz (Echinochloa spp.) e papuã (Urochloa plantaginea) em terras baixas, em combinações de rotação de culturas e do manejo de solo. Foram utilizadas as culturas de arroz, soja e sorgo, sob o manejo de preparo do solo convencional e sistema de semeadura direta, cultivado em faixas. Foi avaliado o banco de sementes de capim-arroz e papuã após dois anos de cultivo, na camada de 0-5 e 5-10 cm de profundidade. A densidade do banco de sementes de capimarroz e papuã foi superior no monocultivo de sorgo em relação ao cultivo de arroz. Não houve diferença do banco de sementes de plantas daninhas entre diferentes camadas de solo, exceto para o papuã no monocultivo de sorgo. O monocultivo de sorgo, sem aplicação de herbicidas em pós-emergência, em terras baixas incrementa o banco de sementes de capim-arroz e papuã
Day and night surgery: is there any influence in the patient postoperative period of urgent colorectal intervention?
Background
Medical activity performed outside regular work hours may increase risk for patients and professionals. There is few data with respect to urgent colorectal surgery. The aim of this work was to evaluate the impact of daytime versus nighttime surgery on postoperative period of patients with acute colorectal disease.
Methods
A retrospective study was conducted in a sample of patients with acute colorectal disease who underwent urgent surgery at the General Surgery Unit of Braga Hospital, between January 2005 and March 2013. Patients were stratified by operative time of day into a daytime group (surgery between 8:00 and 20:59) and the nighttime group (21:00–7:59) and compared for clinical and surgical parameters. A questionnaire was distributed to surgeons, covering aspects related to the practice of urgent colorectal surgery and fatigue.
Results
A total of 330 patients were included, with 214 (64.8 %) in the daytime group and 116 (35.2 %) in the nighttime group. Colorectal cancer was the most frequent pathology. Waiting time (p?<?0.001) and total length of hospital stay (p?=?0.008) were significantly longer in the daytime group. There were no significant differences with respect to early or late complications. However, 100 % of surgeons reported that they are less proficient during nighttime.
Conclusions
Among patients with acute colorectal disease subjected to urgent surgery, there was no significant association between nighttime surgery and the presence of postoperative medical and surgical morbidities. Patients who were subjected to daytime surgery had longer length of stay at the hospital

Burden of injury along the development spectrum: associations between the Socio-demographic Index and disability-adjusted life year estimates from the Global Burden of Disease Study 2017
Background The epidemiological transition of non-communicable diseases replacing infectious diseases as the main contributors to disease burden has been well documented in global health literature. Less focus, however, has been given to the relationship between sociodemographic changes and injury. The aim of this study was to examine the association between disability-adjusted life years (DALYs) from injury for 195 countries and territories at different levels along the development spectrum between 1990 and 2017 based on the Global Burden of Disease (GBD) 2017 estimates. Methods Injury mortality was estimated using the GBD mortality database, corrections for garbage coding and CODEm-the cause of death ensemble modelling tool. Morbidity estimation was based on surveys and inpatient and outpatient data sets for 30 cause-of-injury with 47 nature-of-injury categories each. The Socio-demographic Index (SDI) is a composite indicator that includes lagged income per capita, average educational attainment over age 15 years and total fertility rate. results For many causes of injury, age-standardised DALY rates declined with increasing SDI, although road injury, interpersonal violence and self-harm did not follow this pattern. Particularly for self-harm opposing patterns were observed in regions with similar SDI levels. For road injuries, this effect was less pronounced. Conclusions The overall global pattern is that of declining injury burden with increasing SDI. However, not all injuries follow this pattern, which suggests multiple underlying mechanisms influencing injury DALYs. There is a need for a detailed understanding of these patterns to help to inform national and global efforts to address injury-related health outcomes across the development spectrum
Maternal mortality and morbidity burden in the Eastern Mediterranean region : findings from the Global Burden of Disease 2015 study
Assessing the burden of maternal mortality is important for tracking progress and identifying public health gaps. This paper provides an overview of the burden of maternal mortality in the Eastern Mediterranean Region (EMR) by underlying cause and age from 1990 to 2015.
We used the results of the Global Burden of Disease 2015 study to explore maternal mortality in the EMR countries.
The maternal mortality ratio in the EMR decreased 16.3% from 283 (241-328) maternal deaths per 100,000 live births in 1990 to 237 (188-293) in 2015. Maternal mortality ratio was strongly correlated with socio-demographic status, where the lowest-income countries contributed the most to the burden of maternal mortality in the region.
Progress in reducing maternal mortality in the EMR has accelerated in the past 15 years, but the burden remains high. Coordinated and rigorous efforts are needed to make sure that adequate and timely services and interventions are available for women at each stage of reproductive life
Quantifying risks and interventions that have affected the burden of diarrhoea among children younger than 5 years : an analysis of the Global Burden of Disease Study 2017
Background Many countries have shown marked declines in diarrhoea! disease mortality among children younger than 5 years. With this analysis, we provide updated results on diarrhoeal disease mortality among children younger than 5 years from the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) and use the study's comparative risk assessment to quantify trends and effects of risk factors, interventions, and broader sociodemographic development on mortality changes in 195 countries and territories from 1990 to 2017.
Methods This analysis for GBD 2017 had three main components. Diarrhoea mortality was modelled using vital registration data, demographic surveillance data, and verbal autopsy data in a predictive, Bayesian, ensemble modelling tool; and the attribution of risk factors and interventions for diarrhoea were modelled in a counterfactual framework that combines modelled population-level prevalence of the exposure to each risk or intervention with the relative risk of diarrhoea given exposure to that factor. We assessed the relative and absolute change in diarrhoea mortality rate between 1990 and 2017, and used the change in risk factor exposure and sociodemographic status to explain differences in the trends of diarrhoea mortality among children younger than 5 years.
Findings Diarrhoea was responsible for an estimated 533 768 deaths (95% uncertainty interval 477 162-593 145) among children younger than 5 years globally in 2017, a rate of 78.4 deaths (70.1-87.1) per 100 000 children. The diarrhoea mortality rate ranged between countries by over 685 deaths per 100 000 children. Diarrhoea mortality per 100 000 globally decreased by 69.6% (63.1-74.6) between 1990 and 2017. Among the risk factors considered in this study, those responsible for the largest declines in the diarrhoea mortality rate were reduction in exposure to unsafe sanitation (13.3% decrease, 11.2-15.5), childhood wasting (9.9% decrease, 9.6-10.2), and low use of oral rehydration solution (6.9% decrease, 4-8-8-4).
Interpretation Diarrhoea mortality has declined substantially since 1990, although there are variations by country. Improvements in sociodemographic indicators might explain some of these trends, but changes in exposure to risk factors-particularly unsafe sanitation, childhood growth failure, and low use of oral rehydration solution-appear to be related to the relative and absolute rates of decline in diarrhoea mortality. Although the most effective interventions might vary by country or region, identifying and scaling up the interventions aimed at preventing and protecting against diarrhoea that have already reduced diarrhoea mortality could further avert many thousands of deaths due to this illness
