    Abstract A two-dimensional multichannel seismic reflection profile acquired in the Madeira Abyssal Plain during June 2016 was used in a modeling workflow comprising seismic oceanography processing, geostatistical inversion and Bayesian classification to predict the probability of occurrence of distinct water masses. The seismic section was processed to image in detail the fine scale structure of the water column using seismic oceanography. The processing sequence was developed to preserve, as much as possible, the relative seismic amplitudes of the data and enhance the shallow structure of the water column by effectively suppressing the direct arrival. The migrated seismic oceanography section shows an eddy at the expected Mediterranean Outflow Water depths, steeply dipping reflectors, which indicate the possible presence of frontal activity or secondary dipping eddy structures, and strong horizontal reflections between intermediate water masses suggestive of double diffuse processes. We then developed and applied an iterative geostatistical seismic oceanography inversion methodology to predict the spatial distribution of temperature and salinity. Due to the lack of contemporaneous direct measurements of temperature and salinity we used a global ocean model as spatial constraint during the inversion and nearby contemporaneous ARGO data to infer the expected statistical properties of both model parameters. After the inversion, Bayesian classification was applied to all temperature and salinity models inverted during the last iteration to predict the spatial distribution of three distinct water masses. A preliminary interpretation of these probabilistic models agrees with the expected ocean dynamics of the region.

    Abstract Abstract Background Self-Organizing Maps (SOM) are an unsupervised learning clustering and dimensionality reduction algorithm capable of mapping an initial complex high-dimensional data set into a low-dimensional domain, such as a two-dimensional grid of neurons. In the reduced space, the original complex patterns and their interactions can be better visualized, interpreted and understood. Methods We use SOM to simultaneously couple the spatial and temporal domains of the COVID-19 evolution in the 278 municipalities of mainland Portugal during the first year of the pandemic. Temporal 14-days cumulative incidence time series along with socio-economic and demographic indicators per municipality were analyzed with SOM to identify regions of the country with similar behavior and infer the possible common origins of the incidence evolution. Results The results show how neighbor municipalities tend to share a similar behavior of the disease, revealing the strong spatiotemporal relationship of the COVID-19 spreading beyond the administrative borders of each municipality. Additionally, we demonstrate how local socio-economic and demographic characteristics evolved as determinants of COVID-19 transmission, during the 1st wave school density per municipality was more relevant, where during 2nd wave jobs in the secondary sector and the deprivation score were more relevant. Conclusions The results show that SOM can be an effective tool to analysing the spatiotemporal behavior of COVID-19 and synthetize the history of the disease in mainland Portugal during the period in analysis. While SOM have been applied to diverse scientific fields, the application of SOM to study the spatiotemporal evolution of COVID-19 is still limited. This work illustrates how SOM can be used to describe the spatiotemporal behavior of epidemic events. While the example shown herein uses 14-days cumulative incidence curves, the same analysis can be performed using other relevant data such as mortality data, vaccination rates or even infection rates ...

    Abstract Abstract The rapid spread of the SARS-CoV-2 epidemic has simultaneous time and space dynamics. This behaviour results from a complex combination of factors, including social ones, which lead to significant differences in the evolution of the spatiotemporal pattern between and within countries. Usually, spatial smoothing techniques are used to map health outcomes, and rarely uncertainty of the spatial predictions are assessed. As an alternative, we propose to apply direct block sequential simulation to model the spatial distribution of the COVID-19 infection risk in mainland Portugal. Given the daily number of infection data provided by the Portuguese Directorate-General for Health, the daily updates of infection rates are calculated by municipality and used as experimental data in the geostatistical simulation. The model considers the uncertainty/error associated with the size of each municipality’s population. The calculation of daily updates of the infection risk maps results from the median model of one ensemble of 100 geostatistical realizations of daily updates of the infection risk. The ensemble of geostatistical realizations is also used to calculate the associated spatial uncertainty of the spatial prediction using the interquartile distance. The risk maps are updated daily and show the regions with greater risks of infection and the critical dynamics related to its development over time.

    Abstract Purpose: To describe the use of endocavitary ultrasound probe as an auxiliary tool when performing partial nephrectomy in cases of endophytic renal tumors, to standardize the method, and to report the preliminary results achieved with this technique.
    Methods: Fifteen patients diagnosed with completely endophytic underwent partial nephrectomy with the use of an endocavitary ultrasound probe. This article describes the technique involved in partial nephrectomy and details the preparation of the endocavitary ultrasound probe to ensure its safe use.
    Results: All the patients had a RENAL score between 8 and 11. The median time of warm ischemia was 26 and 18 minutes for laparoscopic or robot-assisted surgery, respectively. The median duration of surgery was 150 minutes, and the median console time was 145 minutes for the laparoscopic and robot-assisted surgery groups, respectively. The median estimate of blood loss was 200 mL. Only three patients in the laparoscopic group had focal positive surgical margins. There were no cases of infection at the site of probe entry.
    Conclusions: Intraoperative use of an endocavitary ultrasound probe for partial nephrectomy is possible and a safe alternative to the excision of endophytic tumors when neither robotic probes nor laparoscopic probes are available.

    Abstract Canola is a product of traditional plant breeding techniques to remove from rapeseed the antinutritional components erucic acid. This crop proves to be a promising crop due to the diverse purposes of its oil, especially by its potential for biofuel production. This paper aimed to integrate the information available in the literature and report the most promising strategies for genetic and biotechnological progress in canola. Thus, we carried out a detailed review of the origin and uses of canola, its socioeconomic importance in the global and Brazilian aspects, tropicalization, with emphasis on genetic breeding. We demonstrate the main breeding strategies that can be used to increase your oil production. We propose here a breeding strategy for canola, in which some strategies previously mentioned are integrated. The purpose of this strategy is to enhance the selection and efficiency at the beginning of a breeding program. Among these, genome wide selection (GWS) is a suitable tool to help breeders to improve the efficiency selection in a canola breeding program increasing the selection accuracy or even reducing the cycle time. The proposed strategies must be analyzed for each situation, adjusting the GWS model to obtain highest selection accuracy.

    Abstract Context: The effects of androgen therapy on arterial function in transgender men (TM) are not fully understood, particularly concerning long-term androgen treatment.
    Objective: To evaluate arterial stiffness in TM receiving long-term gender-affirming hormone therapy by carotid-femoral pulse wave velocity (cf-PWV).
    Methods: A cross-sectional case-control study at the Gender Dysphoria Unit of the Division of Endocrinology, HC-FMUSP, Sao Paulo, Brazil. Thirty-three TM receiving intramuscular testosterone esters as regular treatment for an average time of 14 ± 8 years were compared with 111 healthy cisgender men and women controls matched for age and body mass index. Aortic stiffness was evaluated by cf-PWV measurements using Complior device post-testosterone therapy. The main outcome measure was aortic stiffness by cf-PWV as a cardiovascular risk marker in TM and control group.
    Results: The cf-PWV after long-term testosterone therapy was significantly higher in TM (7.4 ± 0.9 m/s; range 5.8-8.9 m/s) than in cisgender men (6.6 ± 1.0 m/s; range 3.8-9.0 m/s,
    Conclusion: The TM group on long-term treatment with testosterone had higher aging-related aortic stiffening than the control groups. These findings indicate that aortic stiffness might be accelerated in the TM group receiving gender-affirming hormone treatment, and suggest a potential deleterious effect of testosterone on arterial function. Preventive measures in TM individuals receiving testosterone treatment, who are at higher risk for cardiovascular events, are highly recommended.
