PCUMex survey: Controversies in the management of prostate cancer among Mexican urologists

AbstractBackgroundProstate cancer is the first cause of mortality related to malignancy in Mexican men. Common clinical practice has to be evaluated in order to gain a picture of reality apart from the guidelines.AimTo analyze clinical practice among urologists in Mexico in relation to prostate cancer management and to compare the results with current recommendations and guidelines.MethodsWe collected the data from 600 urologists, members of the Sociedad Mexicana de Urología, who were invited by email to answer a survey on their usual decisions when managing controversial aspects of prostate cancer patients.ResultsQuinolones were the most common antibiotic used as prophylaxis in prostate biopsy (75.51%); 10–12 cores were taken in more than 65% of prostate biopsies; and 18.27% of the participants performed limited pelvic lymphadenectomy. Treatment results showed that 10.75% of the urologists surveyed preferred radical prostatectomy as monotherapy in high-risk patients with extraprostatic extension and 60.47% used complete androgen deprivation in metastatic prostate cancer.ConclusionsThere are many areas of opportunity for improvement in our current clinical practice for the management of patients with prostate cancer

Cruise Summary Report - MEDWAVES survey. MEDiterranean out flow WAter and Vulnerable EcosystemS (MEDWAVES)

The MEDWAVES (MEDiterranean out flow WAter and Vulnerable EcosystemS) cruise targeted areas under the potential influence of the MOW within the Mediterranean and Atlantic realms. These include seamounts where Cold-water corals (CWCs) have been reported but that are still poorly known, and which may act as essential “stepping stones” connecting fauna of seamounts in the Mediterranean with those of the continental shelf of Portugal, the Azores and the Mid-Atlantic Ridge. During MEDWAVES sampling has been conducted in two of the case studies of ATLAS: Case study 7 (Gulf of Cádiz-Strait of Gibraltar-Alboran Sea) and Case study 8 (Azores). The initially targeted areas in the Atlantic were: the Gazul Mud volcano, in the Gulf of Cádiz (GoC) area, included in the case study 7, and the Atlantic seamounts Ormonde (Portuguese shelf) and Formigas (by Azores), both part of the case study 8. In the Mediterranean the targeted areas were The Guadiaro submarine canyon and the Seco de los Olivos (also known as Chella Bank) seamount. Unfortunately it was not possible to sample in Guadiaro due to time constraints originated by adverse meteorological conditions which obligate us to reduce the time at sea focusing only in 4 of the 5 initially planned areas. MEDWAVES was structured in two legs; the first leg took place from the 21st September (departure from Cádiz harbour in Spain) to the 13th October 2016 (arrival in Ponta Delgada, São Miguel, Azores, Portugal took place the 8th of October due to the meteorological conditions that obligated to conclude the first leg earlier as planned). during the Leg 1 sampling was carried out in Gazul, Ormonde and Formigas. The second leg started the 14th October (departure from Ponta Delgada) and finished the 26th October (arrival in Málaga harbour, Spain). MEDWAVES had a total of 30 effective sampling days, being 6 days not operative due to the adverse meteorological conditions experienced during the first leg which forced us to stay in Ponta Delgada from the 08th to the 13th October. During MEDWAVES the daily routine followed a similar scheme, depending of course on the weather and sea conditions. The main activity during the day, starting early in the morning (around 08:00 AM, once the night activities were finished), was the ROV deployment. Generally a single ROV dive of around 8 hours was performed, however in several occasions two dives were carried out in the same day (see General station list, Appendix II). After the ROV (and sometimes between two dives) the Box Corer and/or Van Veen Grab and/or Multicore was deployed. After these activities, during the night CTD-Rosette deployments and MB was conducted. Accordingly to this schema the scientific personnel worked in the day or in the night watch. A total of 215 sampling stations have been covered in MEDWAVES, using the following sampling gears: Multibeam echosounder, CTD-Rosette, LADCP, Box Corer, Van Veen Grab, Multicorer and a Remotely Operated Vehicle (ROV). Table 1 sumamrised the number of sampling stations conducted with each gear in each sampling zone. Additionally MB surveys have been conducted during the transits between area

Momentum scale calibration of the LHCb spectrometer

For accurate determination of particle masses accurate knowledge of the momentum scale of the detectors is crucial. The procedure used to calibrate the momentum scale of the LHCb spectrometer is described and illustrated using the performance obtained with an integrated luminosity of 1.6 fb-1 collected during 2016 in pp running. The procedure uses large samples of J/ψ → μ + μ - and B+ → J/ψ K + decays and leads to a relative accuracy of 3 × 10-4 on the momentum scale

Curvature-bias corrections using a pseudomass method

Momentum measurements for very high momentum charged particles, such as muons from electroweak vector boson decays, are particularly susceptible to charge-dependent curvature biases that arise from misalignments of tracking detectors. Low momentum charged particles used in alignment procedures have limited sensitivity to coherent displacements of such detectors, and therefore are unable to fully constrain these misalignments to the precision necessary for studies of electroweak physics. Additional approaches are therefore required to understand and correct for these effects. In this paper the curvature biases present at the LHCb detector are studied using the pseudomass method in proton-proton collision data recorded at centre of mass energy √(s)=13 TeV during 2016, 2017 and 2018. The biases are determined using Z→μ + μ - decays in intervals defined by the data-taking period, magnet polarity and muon direction. Correcting for these biases, which are typically at the 10-4 GeV-1 level, improves the Z→μ + μ - mass resolution by roughly 18% and eliminates several pathological trends in the kinematic-dependence of the mean dimuon invariant mass

The analysis on the human protein domain targets and host-like interacting motifs for the MERS-CoV and SARS-CoV/CoV-2 infers the molecular mimicry of coronavirus.

The MERS-CoV, SARS-CoV, and SARS-CoV-2 are highly pathogenic viruses that can cause severe pneumonic diseases in humans. Unfortunately, there is a non-available effective treatment to combat these viruses. Domain-motif interactions (DMIs) are an essential means by which viruses mimic and hijack the biological processes of host cells. To disentangle how viruses achieve this process can help to develop new rational therapies. Data mining was performed to obtain DMIs stored as regular expressions (regexp) in 3DID and ELM databases. The mined regexp information was mapped on the coronaviruses’ proteomes. Most motifs on viral protein that could interact with human proteins are shared across the coronavirus species, indicating that molecular mimicry is a common strategy for coronavirus infection. Enrichment ontology analysis for protein domains showed a shared biological process and molecular function terms related to carbon source utilization and potassium channel regulation. Some of the mapped motifs were nested on B, and T cell epitopes, suggesting that it could be as an alternative way for reverse vaccinology. The information obtained in this study could be used for further theoretic and experimental explorations on coronavirus infection mechanism and development of medicines for treatment

The Asociación Mexicana de Gastroenterología consensus on the diagnosis and treatment of acute pancreatitis in children and adolescents

Acute pancreatitis (AP) and recurrent acute pancreatitis (RAP) are conditions, whose incidence is apparently on the rise. Despite the ever-increasing evidence regarding the management of AP in children and adults, therapeutic actions that could potentially affect having a poor prognosis in those patients, especially in the pediatric population, continue to be carried out. Therefore, the Asociación Mexicana de Gastroenterología convened a group of 24 expert pediatric gastroenterologists from different institutions and areas of Mexico, as well as 2 pediatric nutritionists and 2 specialists in pediatric surgery, to discuss different aspects of the epidemiology, diagnosis, and treatment of AP and RAP in the pediatric population. The aim of this document is to present the consensus results. Different AP topics were addressed by 6 working groups, each of which reviewed the information and formulated statements considered pertinent for each module, on themes involving recommendations and points of debate, concerning diagnostic or therapeutic approaches. All the statements were presented and discussed. They were then evaluated through a Delphi process, with electronic and anonymous voting, to determine the level of agreement on the statements. A total of 29 statements were formulated, all of which reached above 75% agreement in the first round of voting. Resumen: La pancreatitis aguda (PA) y la pancreatitis aguda recurrente (PAR) son enfermedades cuya incidencia aparentemente va en incremento. A pesar de la creciente evidencia sobre el manejo de la PA en adultos y niños, aún se siguen teniendo conductas que potencialmente podrían impactar en un pronóstico no tan adecuado de estos pacientes, sobre todo en población pediátrica. Es por esto que la Asociación Mexicana de Gastroenterología convocó a un grupo de 24 gastroenterólogos pediatras expertos, de diferentes instituciones y de diferentes zonas geográficas de México, 2 nutriólogas pediatras, así como 2 especialistas en cirugía pediátrica para discutir sobre diferentes aspectos de la epidemiología, diagnóstico y tratamiento de la PA y PAR en población pediátrica. El objetivo de este documento es presentar los resultados obtenidos de este consenso. Se organizaron 6 mesas de trabajo con diferentes tópicos sobre la PA. Cada mesa de trabajo revisó la información y generó los enunciados/declaraciones que consideraron pertinentes para cada módulo, en tópicos que representaran recomendaciones o puntos de debate sobre cuestiones de abordaje diagnóstico o terapéutico. Se presentaron y discutieron todas las declaraciones. Posteriormente, se sometieron a evaluación mediante un proceso Delphi, de voto anónimo, vía electrónica, para conocer el nivel de acuerdo en los enunciados/declaraciones. Se elaboraron un total de 29 enunciados/declaraciones. Todas las declaraciones tuvieron un porcentaje de consenso mayor del 75% en la primera ronda de votación
