ABSTRACTPurpose/ObjectivesThe healthcare workforce is challenged with preparing for the increasing number of older persons and complexities of their healthcare needs. Fellowship trained geriatric dentists are charged with the task of addressing the dental needs of this vastly growing cohort.The purpose of this study is to formulate a set of competencies for Geriatric Dental Fellowship Training Programs.MethodsThe Delphi technique—a series of three rounds of anonymous questionnaires to obtain the opinions of experts without bringing them together.ResultsIn Round 1, we proposed 45 competencies based on findings in previous literature. In Round 2, there were 19 respondents whose edits narrowed our list to 39 competencies proposed by the participants. In Round 3, based on group consensus we formulated a final list of 42 competencies.ConclusionUtilizing the Delphi process, a panel of geriatric dental experts identified a set of core competencies for curriculums in dental fellowship programs.
Introducción: El dopaje es lo contrario a la esencia misma del espíritu deportivo. Este fenómeno es de tal importancia que todos los responsables tanto a nivel educativo, deportivo como político-sanitario, están en la obligación de intentar evitar que se produzca, con el objetivo de proteger la salud de los jóvenes. Material y Método: Revisión bibliográfica de los posibles efectos positivos que tiene la práctica de la Educación Física sobre los jóvenes a la hora de conseguir rechazar el fenómeno del dopaje y en segundo lugar, de la legislación vigente y las diferentes entidades encargadas de controlar el dopaje. Resultados y Discusión: En primer lugar se pueden observar los diferentes estudios que demuestran la capacidad por parte de la Educación Física de influir en los jóvenes de forma positiva a la hora de tomar ciertas decisiones morales y en segundo lugar se puede apreciar la existencia de obligaciones a los Estados por parte del ordenamiento jurídico en lo que se refiere a la lucha contra el dopaje en las aulas. Conclusión: El dopaje debe erradicarse partiendo de un sistema educativo en el que se contemple la labor de los profesores de Educación Física en este ámbito. ; Introduction: Doping is the opposite the sportsmanship essence.

Graphene-based devices are planned to augment the functionality of Si and III-V based technology in radio-frequency (RF) electronics. The expectations in designing graphene field-effect transistors (GFETs) with enhanced RF performance have attracted significant experimental efforts, mainly concentrated on achieving high mobility samples. However, little attention has been paid, so far, to the role of the access regions in these devices. Here, we analyse in detail, via numerical simulations, how the GFET transfer response is severely impacted by these regions, showing that they play a significant role in the asymmetric saturated behaviour commonly observed in GFETs. We also investigate how the modulation of the access region conductivity (i.e., by the influence of a back gate) and the presence of imperfections in the graphene layer (e.g., charge puddles) affects the transfer response. The analysis is extended to assess the application of GFETs for RF applications, by evaluating their cut-off frequency. ; This research was founded by Spanish government grant numbers TEC2017-89955-P (MINECO/AEI/FEDER, UE), TEC2015-67462-C2-1-R (MINECO), IJCI-2017-32297 (MINECO/AEI), FPU16/04043 and FPU14/02579, and the European Union's Horizon 2020 Research and Innovation Program under Grant GrapheneCore2 785219.

In the last years, supercapacitors (SCs) have been proposed as a promising alternative to cover the power density deficiency presented in batteries. Electrical double-layer SCs, pseudocapacitors, and hybrid supercapacitors (HSCs) have shown very attractive features such as high-power density, long cycle life, and tunable specific capacitance. The advances of these energy storage devices made by transition metal oxides (TMOs) and their production in pseudocapacitors and HSCs depend on chemical composition, crystalline structure, morphology, theoretical capacitance, and oxidation states. In this way, this critical review considers several metal oxides (RuO2, MnO2, V2O5, and Co3O4) and their different configurations with diverse carbon-based materials. Energy storage mechanisms and fundamental principles to understand the promising effect of metal oxides in SCs devices are thoroughly described. Special attention as regards to the energy storage mechanisms relative to the specific capacitance values is presented in the reviewed articles. This review envisages the TMO as a key component to obtain high specific capacitance SCs. ; The Peruvian government agencies CONCYTEC and FONDECYT/World Bank (contract 026-2019 FONDECYTBMINC.INV) .

BioFETs based on two-dimensional materials (2DMs) offer a unique opportunity to enhance, at a low cost, the sensitivity of current biosensors enabling the design of compact devices compatible with standard CMOS technology. The unique combination of large exposed surface areas and minimal thicknesses of 2DMs is an outstanding feature for these devices, and the assessment of their behaviour requires combined experimental and theoretical efforts. In this work we present a 2D-material based BioFET simulator including complex electrolyte reactions and analysing different models for the electrolyte– molecule interaction. These models describe how the molecular charge is screened by the electrolyte ions when their distributions are modified. The electrolyte simulation is validated against experimental results as well as against the analytical predictions of the Debye–H¨uckel approximation. The role of the electrolyte charge screening as well as the impact of the interaction model on the device responsivity are analysed in detail. The results are discussed in order to conclude about the consequences of employing different interaction approximations for the simulation of BioFETs and more generally on the correct modelling of biomolecule-device interaction in BioFETs. ; The authors would like to thank the nancial support of Spanish Government under project TEC2017-89955-P (MINECO/AEI/FEDER,UE).

Background: Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction. Methods: This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index 60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models were used to explore the associations between lockdowns and non-operation. Intervals from diagnosis to surgery were compared across COVID-19 government response index groups. This study was registered at ClinicalTrials.gov, NCT04384926. Findings: Of eligible patients awaiting surgery, 2003 (10·0%) of 20 006 did not receive surgery after a median follow-up of 23 weeks (IQR 16-30), all of whom had a COVID-19-related reason given for non-operation. Light restrictions were associated with a 0·6% non-operation rate (26 of 4521), moderate lockdowns with a 5·5% rate (201 of 3646; adjusted hazard ratio [HR] 0·81, 95% CI 0·77-0·84; p<0·0001), and full lockdowns with a 15·0% rate (1775 of 11 827; HR 0·51, 0·50-0·53; p<0·0001). In sensitivity analyses, including adjustment for SARS-CoV-2 case notification rates, moderate lockdowns (HR 0·84, 95% CI 0·80-0·88; p<0·001), and full lockdowns (0·57, 0·54-0·60; p<0·001), remained independently associated with non-operation. Surgery beyond 12 weeks from diagnosis in patients without neoadjuvant therapy increased during lockdowns (374 [9·1%] of 4521 in light restrictions, 317 [10·4%] of 3646 in moderate lockdowns, 2001 [23·8%] of 11 827 in full lockdowns), although there were no differences in resectability rates observed with longer delays. Interpretation: Cancer surgery systems worldwide were fragile to lockdowns, with one in seven patients who were in regions with full lockdowns not undergoing planned surgery and experiencing longer preoperative delays. Although short-term oncological outcomes were not compromised in those selected for surgery, delays and non-operations might lead to long-term reductions in survival. During current and future periods of societal restriction, the resilience of elective surgery systems requires strengthening, which might include protected elective surgical pathways and long-term investment in surge capacity for acute care during public health emergencies to protect elective staff and services.
