    Abstract Quantitative approaches encompassing parallel reaction monitoring (PRM), data-independent acquisition (DIA), and data-dependent acquisition (DDA) are commonly used to investigate protein expression profiles. However, analytical performances of assays developed using PRM, DIA, and Tandem Mass Tag (TMT)-based DDA for quantitative proteomics have yet not been investigated. Here, we developed assays for glycopeptides identified from six glycoproteins, including Leucine-rich alpha-2-glycoprotein (LRG1), Prostaglandin-H2 D-isomerase (PTGDS), Aminopeptidase N (ANPEP), CD63 antigen (CD63), Clusterin (CLU), and Prostatic acid phosphatase (ACPP), using PRM, DDA, and DIA and evaluated the analytical performances of each assay using the different acquisition modes. We also compared assays in each acquisition mode on three different orbitrap instruments: Thermo Fisher Q Exactive, Exploris 480, and Lumos. We found that DIA showed the largest linear range, highest sensitivity, and most reproducibility. We then applied our developed DIA assays to urine samples from non-aggressive (n = 48) and aggressive (n = 35) prostate cancer patients. In conclusion, we developed assays for the six glycoproteins, evaluated the analytical performances of each assay in DIA, PRM, and PRM acquisition modes on three types of mass spectrometry instruments, and chose the DIA assays for the quantitative analysis of urine samples from patients with aggressive and non-aggressive prostate cancer.

    Abstract As radiation oncologists, we often participate in discussions on work-life balance, are offered lectures and free meals, and complete hospital-mandated modules, all under the guise of physician wellness. But how often are these measures efficacious? How do we define being well in our demanding and fast-paced careers? What does it actually look like on a day-to-day basis to achieve work-life balance? Furthermore, is it even possible?

    Title translation Modelo predictivo de dermatitis alérgica de contacto en pacientes con eccema de manos.
    Abstract Introduction: Patch tests are only indicated for hand eczema when it is diagnosed as chronic. A positive reaction of current relevance requires a change in treatment strategy. Knowing which clinical factors are associated with current relevance would allow tests to be performed sooner.
    Objective: To develop a model for predicting currently relevant patch test positivity in patients with hand eczema only.
    Material and methods: Retrospective study of patients with hand eczema only. We collected data on age, sex, time since onset, occupation, and history of atopic dermatitis. We built a predictive logistic regression model and assessed discrimination by computing the area under the receiver operating characteristic curve.
    Results: We included 262 patients; 66.03% had positive patch tests (28.6% of current relevance). Univariate analysis detected significant associations between positivity of current relevance and employment as a hairdresser-aesthetician, a personal history of atopy, male sex, and a time since onset of over 6 months. Multivariate analysis confirmed employment as a hairdresser-aesthetician as an independent risk factor and male sex and a personal history of atopy as protective factors. The score suggested by the predictive model was 2.316(hairdresser-aesthetician)-1.792(atopic dermatitis)-0.601(male sex).
    Conclusions: Occupation, sex, and a history of atopy influence the likelihood of patch test positivity of current relevance in patients with hand eczema in Spain. Our model suggests that a diagnosis of chronic eczema is not necessarily an indication for patch testing. Future studies with larger samples are needed to determine the true usefulness of predictive models in this setting.

    Abstract Despite considerable efforts, accurate computations of electron-phonon and carrier transport properties of low-dimensional materials from first principles have remained elusive. By building on recent advances in the description of long-range electrostatics, we develop a general approach to the calculation of electron-phonon couplings in two-dimensional materials. We show that the nonanalytic behavior of the electron-phonon matrix elements depends on the Wannier gauge, but that a missing Berry connection restores invariance to quadrupolar order. We showcase these contributions in a MoS_{2} monolayer, calculating intrinsic drift and Hall mobilities with precise Wannier interpolations. We also find that the contributions of dynamical quadrupoles to the scattering potential are essential, and that their neglect leads to errors of 23% and 76% in the room-temperature electron and hole Hall mobilities, respectively.

    Abstract Introduction: The incidence of skin cancer, for which the main risk factor is exposure to ultraviolet radiation, has risen worldwide. Sunburn is one of the simplest ways to assess sun exposure habits. To date, few studies have evaluated sun exposure in university students.
    Objectives: To determine behaviors, attitudes, and knowledge related to sun exposure and sun protection measures among medical students at the Universidad de Las Palmas de Gran Canaria; and to assess their relation to sunburn frequency.
    Material and methods: The voluntary participants in this cross-sectional survey were first-, second- and sixth-year university students enrolled during the 2016-2017 academic year. The students responded to a validated questionnaire about their habits, attitudes, and knowledge in relation to sun exposure. Respondents were grouped according to the number of sunburns they had experienced during the previous summer.
    Results: A total of 286 students responded. The students demonstrated a high level of knowledge, but the percentage who experienced a sunburn was high. Multivariate analysis showed independent correlations between experiencing a sunburn and age, male sex, academic year of enrollment at the time of the survey, phototype, and negative attitudes toward the use of sun protection measures.
    Conclusions: Our medical students' level of knowledge about sun exposure and sun protection is high and scarcely varies with time spent at the university. However, their knowledge is not reflected in their behavior and attitudes or in the frequency of sunburns.
