Basal Cell Carcinoma: Incidence and Trends in Valencia, Spain. / Carcinoma basocelular: incidencia y tendencias en Valencia (España).

BACKGROUND: There is a need for epidemiological and incidence data on the occurrence of basal cell carcinoma (BCC) in Spain. OBJECTIVES: Our study was designed to retrospectively retrieve cases from our computer databases from 2010 through 2016 to provide updated data on the actual incidence of BCC in Valencia, eastern Spain. MATERIAL AND METHODS: This was an epidemiological study on basal cell carcinoma conducted in Valencia, eastern Spain. We analyzed a total of 2171 patients and 4047 tumors, and gathered data to estimate the actual incidence of BBC in our region. RESULTS AND CONCLUSIONS: Our study confirmed that the incidence of BCC is much higher than previously reported. We calculated a crude incidence of 410.38 BCCs/100 000 person-years, an adjusted rate for the European population of 256.98 BCCs/100 000 person-years, and an adjusted rate for the world population of 196.26 BCCs/100 000 person-years. Risk is up to 29.49% higher for men (464.07 cases/100 000 person-years vs 358.40 cases/100 000 person-years for women). Incidence also increases by an annual 3.91% (a significantly higher annual incidence of 8.28% in women vs a 0.92% annual incidence in men). Overall, the lifetime risk for developing a BCC is 5.8% (5.02% in women and 7% in men).

Nuclear Charge Radius of

Collinear laser spectroscopy was performed on the isomer of the aluminium isotope ^{26m}Al. The measured isotope shift to ^{27}Al in the 3s^{2}3p ^{2}P_{3/2}^{○}→3s^{2}4s ^{2}S_{1/2} atomic transition enabled the first experimental determination of the nuclear charge radius of ^{26m}Al, resulting in R_{c}=3.130(15) fm. This differs by 4.5 standard deviations from the extrapolated value used to calculate the isospin-symmetry breaking corrections in the superallowed ß decay of ^{26m}Al. Its corrected Ft value, important for the estimation of V_{ud} in the Cabibbo-Kobayashi-Maskawa matrix, is thus shifted by 1 standard deviation to 3071.4(1.0) s.

Nuclear moments of indium isotopes reveal abrupt change at magic number 82.

In spite of the high-density and strongly correlated nature of the atomic nucleus, experimental and theoretical evidence suggests that around particular 'magic' numbers of nucleons, nuclear properties are governed by a single unpaired nucleon1,2. A microscopic understanding of the extent of this behaviour and its evolution in neutron-rich nuclei remains an open question in nuclear physics3-5. The indium isotopes are considered a textbook example of this phenomenon6, in which the constancy of their electromagnetic properties indicated that a single unpaired proton hole can provide the identity of a complex many-nucleon system6,7. Here we present precision laser spectroscopy measurements performed to investigate the validity of this simple single-particle picture. Observation of an abrupt change in the dipole moment at N = 82 indicates that, whereas the single-particle picture indeed dominates at neutron magic number N = 82 (refs. 2,8), it does not for previously studied isotopes. To investigate the microscopic origin of these observations, our work provides a combined effort with developments in two complementary nuclear many-body methods: ab initio valence-space in-medium similarity renormalization group and density functional theory (DFT). We find that the inclusion of time-symmetry-breaking mean fields is essential for a correct description of nuclear magnetic properties, which were previously poorly constrained. These experimental and theoretical findings are key to understanding how seemingly simple single-particle phenomena naturally emerge from complex interactions among protons and neutrons.

Large Shape Staggering in Neutron-Deficient Bi Isotopes.

The changes in the mean-square charge radius (relative to ^{209}Bi), magnetic dipole, and electric quadrupole moments of ^{187,188,189,191}Bi were measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). A large staggering in radii was found in ^{187,188,189}Bi^{g}, manifested by a sharp radius increase for the ground state of ^{188}Bi relative to the neighboring ^{187,189}Bi^{g}. A large isomer shift was also observed for ^{188}Bi^{m}. Both effects happen at the same neutron number, N=105, where the shape staggering and a similar isomer shift were observed in the mercury isotopes. Experimental results are reproduced by mean-field calculations where the ground or isomeric states were identified by the blocked quasiparticle configuration compatible with the observed spin, parity, and magnetic moment.

Evidence of a sudden increase in the nuclear size of proton-rich silver-96.

Understanding the evolution of the nuclear charge radius is one of the long-standing challenges for nuclear theory. Recently, density functional theory calculations utilizing Fayans functionals have successfully reproduced the charge radii of a variety of exotic isotopes. However, difficulties in the isotope production have hindered testing these models in the immediate region of the nuclear chart below the heaviest self-conjugate doubly-magic nucleus 100Sn, where the near-equal number of protons (Z) and neutrons (N) lead to enhanced neutron-proton pairing. Here, we present an optical excursion into this region by crossing the N = 50 magic neutron number in the silver isotopic chain with the measurement of the charge radius of 96Ag (N = 49). The results provide a challenge for nuclear theory: calculations are unable to reproduce the pronounced discontinuity in the charge radii as one moves below N = 50. The technical advancements in this work open the N = Z region below 100Sn for further optical studies, which will lead to more comprehensive input for nuclear theory development.

Life cycle assessment, C footprint and carbon balance of virgin olive oils production from traditional and intensive olive groves in southern Spain.

Olive oil production shapes the socio-economic and environmental life of many areas of the Mediterranean basin, especially southern Spain, the highest olive oil-producing region worldwide. Olive grove cultivation is tending to intensify from traditional low-density to intensive and high-density cropping systems, which might result in higher environmental impacts. The aim of this study is to estimate the environmental impacts, carbon (C) footprint and carbon balance of producing virgin origin olive oil in Spain from four traditional rainfed, four irrigated, and three intensive olive farms, including the processing phase. Environmental impacts of producing 1 kg of unpacked virgin olive oil at the farm and industrial phases were quantified with the Life Cycle Assessment (LCA) tool and a "cradle-to-gate" approach using data from surveys at these farms and 12 olive oil mills. On average, the farming phase accounted for 76.3% of the EIs. Therefore, to reduce the impact of the virgin olive oils production, most of the efforts should be made especially in the farming phase. Despite the high variability between seasons and between independent replicates of the same farming system, intensive farming had significant higher impacts on most environmental impact categories than traditional rainfed farming, mainly due to the application of nitrogen fertilizer, plant protection products and herbicides. In terms of climate change, the environmental impact of the functional unit is in the ranges of 1.80-2.41, 1.59-2.78 and 2.28-3.26 kg of CO2 eq. for traditional rainfed, irrigated and intensive, respectively. C footprint was negative and averaged -5.5, -4.3 and -2.7 kg CO2 eq. Olive groves are efficient atmospheric CO2 sinks mainly by fixing CO2 into permanent and non-permanent trees structures. The lower intensification of the traditional rainfed groves contributed more in mitigating the increase of atmospheric CO2. Finally, the C footprint and C balance are negative, especially in traditional irrigated and intensive farming. The application of organic sources of fertilizer and the implementation of temporary spontaneous cover crops, both technically and economically feasible, are sound strategies to achieve a positive carbon balance and reduce the impacts of olive cultivation.

Factores relacionados con una respuesta inmediata a los síntomas en pacientes con ictus o accidente isquémico transitorio / Factors related to immediate response to symptoms in patients with stroke or transient ischaemic attack

INTRODUCCIÓN: Pese a los recientes avances en el manejo agudo del ictus, se aplican terapias de reperfusión a menos de un 10% de los pacientes. Una de las causas es el retraso en la búsqueda de atención médica por el paciente y sus familiares, que analizaremos a continuación. MÉTODOS: Se realizó un estudio observacional, prospectivo, en pacientes consecutivos con ictus o accidente isquémico transitorio. Se recogieron parámetros sociodemográficos y clínicos, y datos sobre el retraso en la decisión, retraso prehospitalario y el tipo de contacto médico seleccionado. Se realizaron análisis descriptivo, bivariante y multivariante para determinar los factores relacionados con la búsqueda de atención médica en los primeros 15minutos. RESULTADOS: Se recogieron 382 pacientes. Un 24,9% decidió solicitar atención médica en los primeros 15 minutos. Lo favorecieron la severidad del evento (OR: 1,08; IC 95%: 1,04-1,13; p < 0,001), estar acompañado de un hijo (OR: 3,44; IC 95%: 1,88-6,27; p < 0,001) y el tratamiento con insulina (OR: 2,89; IC 95%: 1,35-6,20; p = 0,006). Los infartos lacunares (OR: 0,41; IC 95%: 0,17-0,97; p = 0,042), los infartos parciales de circulación anterior (OR: 0,43; IC 95%: 0,22-0,85; p = 0,015) y los cuadros monosintomáticos sin afasia o paresia de miembros (OR: 0,15; IC 95%: 0,033-0,724; p = 0,018) se relacionaron con retrasos mayores de 15 minutos. CONCLUSIONES: La severidad y estar acompañado de un hijo fueron los principales determinantes de una reacción inmediata. Futuras intervenciones deben promocionar una consulta inmediata independientemente de la severidad, así como incidir en un mayor abanico de síntomas

INTRODUCTION: Despite recent advances in the management of acute stroke, fewer than 10% of patients receive reperfusion therapy. One of the main reasons for such a low rate of administration is the delay on the part of patients and their families in seeking medical attention. This study aimed to analyse this delay. METHODS: A prospective observational study was conducted on consecutive stroke or transient ischaemic attack. Data on sociodemographic and clinical parameters, decision delay, pre-hospital delay, and first medical contact were collected. Descriptive, bivariate, and multivariate logistic regression analyses were performed to determine factors associated with seeking medical attention within the first 15minutes of stroke or TIA occurrence. RESULTS: A total of 382 patients were included, 24.9% of whom had a decision delay of 15 minutes or less. Stroke severity (OR 1.08; 95% CI, 1.04-1.13; P < .001), patient's son/daughter witnessing the event (OR 3.44; 95% CI, 1.88-6.27; P < .001), and insulin treatment (OR 2.89; 95% CI, 1.35-6.20; P = .006) were related to an immediate reaction. Lacunar infarcts (OR 0.41; 95% CI, 0.17-0.97; P=.042), partial anterior circulation infarcts (OR 0.43; 95% CI, 0.22-0.85; P = .015), and monosymptomatic events not involving limb paresis or aphasia (OR 0.15; 95% CI, 0.033-0.724; P = .018) favoured delays longer than 15 minutes. CONCLUSIONS: Severity of the event and presence of a son/daughter are the factors most frequently associated with an immediate response to stroke. Future interventions should emphasise the need for an immediate response irrespective of severity and include a wider spectrum of symptoms

Laser spectroscopy of indium Rydberg atom bunches by electric field ionization.

This work reports on the application of a novel electric field-ionization setup for high-resolution laser spectroscopy measurements on bunched fast atomic beams in a collinear geometry. In combination with multi-step resonant excitation to Rydberg states using pulsed lasers, the field ionization technique demonstrates increased sensitivity for isotope separation and measurement of atomic parameters over previous non-resonant laser ionization methods. The setup was tested at the Collinear Resonance Ionization Spectroscopy experiment at ISOLDE-CERN to perform high-resolution measurements of transitions in the indium atom from the [Formula: see text] and [Formula: see text] states to [Formula: see text]p [Formula: see text]P and [Formula: see text]F Rydberg states, up to a principal quantum number of [Formula: see text]. The extracted Rydberg level energies were used to re-evaluate the ionization potential of the indium atom to be [Formula: see text]. The nuclear magnetic dipole and nuclear electric quadrupole hyperfine structure constants and level isotope shifts of the [Formula: see text] and [Formula: see text] states were determined for [Formula: see text]In. The results are compared to calculations using relativistic coupled-cluster theory. A good agreement is found with the ionization potential and isotope shifts, while disagreement of hyperfine structure constants indicates an increased importance of electron correlations in these excited atomic states. With the aim of further increasing the detection sensitivity for measurements on exotic isotopes, a systematic study of the field-ionization arrangement implemented in the work was performed at the same time and an improved design was simulated and is presented. The improved design offers increased background suppression independent of the distance from field ionization to ion detection.

Spectroscopy of short-lived radioactive molecules.

Molecular spectroscopy offers opportunities for the exploration of the fundamental laws of nature and the search for new particle physics beyond the standard model1-4. Radioactive molecules-in which one or more of the atoms possesses a radioactive nucleus-can contain heavy and deformed nuclei, offering high sensitivity for investigating parity- and time-reversal-violation effects5,6. Radium monofluoride, RaF, is of particular interest because it is predicted to have an electronic structure appropriate for laser cooling6, thus paving the way for its use in high-precision spectroscopic studies. Furthermore, the effects of symmetry-violating nuclear moments are strongly enhanced5,7-9 in molecules containing octupole-deformed radium isotopes10,11. However, the study of RaF has been impeded by the lack of stable isotopes of radium. Here we present an experimental approach to studying short-lived radioactive molecules, which allows us to measure molecules with lifetimes of just tens of milliseconds. Energetically low-lying electronic states were measured for different isotopically pure RaF molecules using collinear resonance ionisation at the ISOLDE ion-beam facility at CERN. Our results provide evidence of the existence of a suitable laser-cooling scheme for these molecules and represent a key step towards high-precision studies in these systems. Our findings will enable further studies of short-lived radioactive molecules for fundamental physics research.
