Published: December 2020

Background: Cytokine levels can be changed in methamphetamine (METH) use disorders (MUDs) and primary psychosis. The present study assessed serum levels of some kinds of interleukins (ILs) in METH-associated psychosis (MAP) and their relationships with psychotic symptoms and cognitive dysfunction.Methods: Serum IL-2R, IL-6, IL-8, and IL-10 levels were examined by chemiluminescence assays in MAP patients (n = 119) and healthy controls (n = 108). The Positive and Negative Syndrome Scale (PANSS) and Montreal Cognitive Assessment (MOCA) were administered.Results: Serum levels of IL-6 and IL-8 were significantly increased in MAP patients (all p &lt; 0.05). There was a negative relationship between IL-2R levels and PANSS positive (P) subscale scores (r = −0.193, p = 0.035). IL-6, IL-8 and IL-10 levels were all negatively correlated with the naming, delayed recall and orientation subscores on the MOCA (r = −0.209, p = 0.022; r = −0.245, p = 0.007; r = −0.505, p &lt; 0.001, respectively).Conclusions: Our results indicate that immune disturbances are related to MAP and that IL-2R, IL-6, IL-8, and IL-10 are associated with the severity of psychotic symptoms and cognitive function impairment.

Background: Despite the high participation rates in the Basque Country, colorectal cancer screening programme (Spain), there is still a part of the population that has never participated. Since it is essential to ensure equal access to health services, it is necessary to identify the determinants of health and socio-economic factors related to non-participation in the screening programme.Methods: Cross sectional descriptive study including all invited population in a complete round between 2015 and the first trimester of 2017. Health risk factors available in medical records and their control have been analyzed using univariate and multivariate analyses.Results: 515,388 people were invited at the programme with a 71.9% of fecal immunochemical test participation rate. Factors that increase the risk of non-participation are: being men (OR = 1.10, 95% CI 1.09–1.12); younger than 60 (OR = 1.18, 95% CI 1.17–1.20); smoker (OR = 1.20, 95% CI 1.18–1.22); hypertensive (OR = 1.14, 95% CI 1.12–1.15) and diabetic (OR = 1.40, 95% CI 1.36–1.43); having severe comorbidity (OR = 2.09, 95% CI 2.00–2.19) and very high deprivation (OR = 1.15, 95% CI 1.12–1.17), as well as making &lt;6 appointments to Primary Care in 3 years (OR = 2.39, 95% CI 2.33–2.45). Still, the area under the curve (AUC) indicates that there are more factors related to non-participation.Conclusions: The participation in the Basque Country colorectal cancer-screening Programme is related to some risk factors controlled by Primary Care among others. Therefore, the involvement of these professionals could improve, not only the adherence to the CRC screening, but also other health styles and preventive interventions.

Published: December 2020

Background: Europe overall suffered greatly in the early stages of the COVID-19 pandemic but the impact of different countries varied. Italy was in the forefront, but there too there were differences, with the Lombardy region the epicentre of the pandemic.Methods: We report Crude Mortality Rates (CMRs) from deaths reported as due to COVID-19 and, in five countries where age-specific data are available, Standardized Mortality Rates (SMRs) in the European Union and United Kingdom.Results: As of 30th August 2020, Belgium was the country with the highest cumulative CMR (86.3/100,000), but the Lombardy region reached almost double this figure (167.6/100,000), far ahead of the corresponding figure for the rest of Italy at 37.0/100,000. SMRs could be calculated for five countries (Italy, Portugal, Sweden, Germany, and Netherlands). Among them, Sweden had the highest SMR (61.6/100,000). The corresponding figures for Italy, Netherlands, Portugal and Germany were 50.2, 41.4, 15.9, and 10.1 per 100,000, respectively.Conclusion: It is clear that countries within Europe have performed very differently in their responses to the COVID-19 pandemic, but the many limitations in the available data must be addressed before a definitive assessment of the reasons for these differences can be made.
Calibration curve for the photoluminescence method after electron irradiation for quantifying low-level carbon in silicon

Published: December 2020

Abstract
As an extension of the standardization of the photoluminescence method after electron irradiation [Tajima et al., Jpn. J. Appl. Phys. 59, SGGK05 (2020)], we present the calibration curve for quantifying C impurities ranging from 1 × 1014 to 3 × 1015 cm−3 in Czochralski-grown Si with resistivity higher than 50 Ω · cm (n-type) and than 5 kΩ · cm (p-type) and with the O concentration of 1.5 × 1017 cm−3. The intensity ratio of the G-line to the intrinsic emission normalized by the ratio of the reference sample was used as an index of the C concentration. The curve was determined as quadratic formulas by the substantial agreement between the theory and the experimental data, which allowed us to expand the applicability of the curve to the O concentration range up to 5.5 × 1017 cm−3. We showed that the relative root-mean-square discrepancy of the C concentration from values determined by secondary ion mass spectroscopy was 16%.

Published: December 2020

Abstract
A high-frequency pulse and a short pulse were generated using a quantum dot (QD) mode-locked laser diode (MLLD). We adopted a highly stacked QD structure using a strain-compensation technique within the active region of the QD-MLLD to fabricate a short-cavity MDDL. A two-section MLLD structure was fabricated with a cavity length of 500 μm. This laser exhibited lasing with a threshold current of approximately 34 mA with zero bias within the saturable absorber region. The spectrum of this laser has a well-defined, wide-range longitudinal mode. A short pulse of 464 fs in width and a high repetition rate of 81 GHz was observed through an interference measurement using a Michelson interferometer.

Obesity and Oesophageal Adenocarcinoma: Underlying Mechanisms
Authors: Fairhurst Natalie , Owen Richard 
Published: December 2020

The incidence of oesophageal adenocarcinoma (OA) in the Western World has drastically increased by almost 400% in the last 30 years, making it the 8th most common cancer in the World. This cancer normally presents in late-stage disease meaning that therapeutic options are limited. Given this, identification of modifiable predisposing factors is crucial in order that therapeutic intervention can be targeted correctly.
In the present case report, we describe the case of a 59 year-old woman diagnosed with T2 oesophageal adenocarcinoma on a background of BMI 49 and few other predisposing co-morbidities. This case highlights the difficulty in identfying causal relationships between obesity and oesophageal adnocarcinoma, and the limitations this brings to managing cases in practice. Further evidence is needed to define the pathophysiology of the disease as well as potential predisposing factors which can be targeted therapeutically to mitigate against disease development and progression.
Characterization of Cosmic Grain Analogs Formed at Low Temperature from Small Hydrocarbon Precursors in the NASA Ames COSmIC Facility
Authors: Sciamma-O’Brien Ella , Salama Farid 
Published: December 2020

Abstract
Here, we present the results of the first solid-phase ex situ analysis of cosmic grain analogs produced at low temperature (<200 K) in the NASA Ames COsmic SImulation Chamber (COSmIC) from small hydrocarbon precursors, methane (CH4) and acetylene (C2H2), seeded in an argon supersonic jet expansion and submitted to a plasma discharge. The plasma-induced chemical reactions, initiated between the precursor molecules and their atomic and molecular fragments, radicals and ions, produce larger molecules and eventually solid particles that are collected in situ under controlled conditions. Scanning electron microscopy (SEM) imaging was used to provide insight on the morphology and growth structure of the grains produced in COSmIC, and to investigate how the precursors used to produce the grains affect these parameters. This SEM study has shown that under identical experimental conditions with fixed physical and chemical parameters (precursor density, temperature, energy, and reaction time), heavier precursors in the initial mixture produce larger grains and in larger quantity, most likely as a result of a more complex chemistry: most of the grains produced in the Ar/CH4 (95:5) gas mixture ranged from 15 to 385 nm in diameter with an average density of 2.1 grains μm−2, while the grains produced in the Ar/C2H2 (95:5) gas mixture ranged from 40 to 650 nm with a density of 3.5 grains μm−2. Changes in the morphology were also observed, with grains produced from acetylene (C2H2) precursors tending to be more spherical than grains produced from methane (CH4) precursors. This change in morphology could be associated with different stages of growth formation at low temperature from a more “planar” growth at first, followed by coagulation into more spherical particles. This study demonstrates that the COSmIC experimental setup can be used to investigate carbon grain formation from small gas-phase molecular precursors at low temperature (<200 K), i.e., under a temperature regime that is representative of the dust condensation zone and outer region of circumstellar envelopes.
Peculiarities in the Horizontal Branch Stars of Globular Cluster NGC 1851: Discovery of a Blue Straggler Companion to an EHB Star

Abstract
We present a study of far-UV (FUV) bright horizontal branch (HB) stars to understand the peculiarities seen in the HB sequence of the globular cluster NGC 1851, using ground- and space-based multiwavelength data. Optical and UV color–magnitude diagrams are used to classify HB stars and their membership from Hubble Space Telescope and Gaia DR2 data. The spectral energy distributions (SEDs) of the hot HB stars located from the core to tidal radii are constructed. The SEDs reveal that the HB stars near the “Grundahl jump” show a decrease in the FUV flux when atmospheric models of cluster metallicity are used for fitting, but a better fit is found with higher-metallicity models, as expected due to atmospheric diffusion. We report on four particularly interesting extreme HB (EHB) stars, two each in the inner and outer regions. We detect a subluminous EHB and “blue-hook” candidates with temperatures T
eff ∼ 25,000 K and 31,000 K, respectively. We found an EHB star (T
eff ∼ 17,000 K) with a radius that lies between the BHB and normal EHB stars. The most peculiar of our EHB stars (T
eff ∼ 28,000 K) is found to be a photometric binary to a blue straggler star (BSS; T
eff ∼ 7000 K), which is an important target for spectroscopic study. This discovery of the candidate EHB+BSS binary system could help to explain the mass loss in the red giant branch phase, leading to the formation of EHB stars.
Résilience urbaine et pouvoir princier : Saint-Omer à la fin du XV e siècle
Authors: Santamaria Jean-Baptiste 
Published: December 2020

Pays potentiellement riche, l’Artois est affecté par une guerre continue pendant les derniers siècles du Moyen Âge et la première modernité. Saint-Omer, extrêmement prospère jusqu’au xiii e siècle, subit ensuite une crise très profonde. La maison de Bourgogne puis les Habsbourg s’efforcent de remédier à ses difficultés, à la fois pour consolider sa fidélité et tenir solidement le plat pays dont elle constitue la clé. Le prince est d’autre part considéré, dans le cadre d’une vision du monde forgée par l’Antiquité (Aristote), le christianisme (saint Augustin) et le Moyen Âge (saint Thomas), comme le protecteur qui permet à la cité de se redresser et de retrouver son rang après les catastrophes. Les moyens dont il dispose dépendent par ailleurs évidemment de la bonne santé financière de ses pays, en particulier de ses bonnes villes. Les exigences liées à la guerre entravent cependant la résilience : l’entretien des armées et l’édification des fortifications écrasent une cité très endettée que l’insécurité empêche de préserver sa fonction commerciale. Le pouvoir princier s’efforce d’intervenir mais ses moyens restent réduits, d’autant que la résistance aux attaques françaises reste la priorité absolue, dans un contexte où la défaite pourrait provoquer la destruction de la ville.
« Classer des lettres classer une vie »
Authors: Paulhan Claire 
Published: December 2020

Éditer des correspondances entre écrivains constitue, depuis toujours, un domaine particulier de l’édition, qui se raréfie cependant : est-ce parce que publier ce genre de titres exige de longs travaux de recherche dans les fonds d’archives ? Est-ce parce que ces correspondances demandent un double appareil critique, ou parce qu’elles ne concernent qu’un public lettré ? Pourtant, l’édition de correspondances a évolué et, après avoir enrichi l’étude des œuvres, elle apporte aujourd’hui quantité de détails concrets et d’informations à l’histoire littéraire et souvent à l’histoire tout court.
Comment on écrit des lettres de Fernando Pessoa
Authors: Eiras Pedro 
Published: December 2020

En 2016, Pedro Eiras publie un livre intitulé Cartas Reencontradas [ Lettres retrouvées ] de Fernando Pessoa a Mário de Sá-Carneiro . En fait, il n’a pas retrouvé les lettres mythiques que Pessoa a écrites à son ami Sá-Carneiro, et qui se sont perdues à la suite du suicide de ce dernier : il a fallu qu’il les invente d’un bout à l’autre. Comment écrit-on des lettres disparues de Fernando Pessoa ? Cet article, publié en portugais dans A Phala , en 2018, a été traduit en français pour Sigila par Agnès Levécot.
