Abstract
The COVID-19 pandemic presented high mortality from its beginning, without effective treatment for seriously ill patients. Build on the experience in Argentine hemorrhagic fever with convalescent plasma, we incorporated 90 patients with COVID-19, of which 87 were evaluable, into a multicenter study. We collected 397 plasma donations from 278 convalescent donors. Patients received plasma with an IgG concentration of 0.7-0.8 (measured by Abbott chemiluminescence) for every 10 kg of body weight. Survival during the first 28 days was the primary objective; 77% were male, age 54 ± 15.6 y/o (range 27-85), body mass index 29.7 ± 4.4; hypertension 39% and diabetes 20.7%; 19.5% had an immunosuppressive condition, 23% were health workers. Plasma was administered to 55 (63%) on spontaneous breathing with oxygen supplementation (mainly oxygen mask with reservoir bag in 80%), and to 32 patients (37%) on mechanical ventilation. The 28-day survival rate was 80%; 91% in patients infused on spontaneous breathing and 63% in those on mechanical ventilation (p = 0.0002). There was a significant improvement in the WHO pneumonia clinical scale at 7 and 14 days, and in PaO2 / FiO2, ferritin and LDH, in the week post-infusion. We observed an episode of circulatory volume overload and a febrile reaction, both mild. Convalescent plasma infusions are feasible, safe, and potentially effective, especially before requiring mechanical ventilation. They are an attractive clinical option for treating severe forms of COVID-19 until other effective therapies become available.

Abstract
SuperCam is a highly integrated remote-sensing instrumental suite for NASA's Mars 2020 mission. It consists of a co-aligned combination of Laser-Induced Breakdown Spectroscopy (LIBS), Time-Resolved Raman and Luminescence (TRR/L), Visible and Infrared Spectroscopy (VISIR), together with sound recording (MIC) and high-magnification imaging techniques (RMI). They provide information on the mineralogy, geochemistry and mineral context around the Perseverance Rover. The calibration of this complex suite is a major challenge. Not only does each technique require its own standards or references, their combination also introduces new requirements to obtain optimal scientific output. Elemental composition, molecular vibrational features, fluorescence, morphology and texture provide a full picture of the sample with spectral information that needs to be co-aligned, correlated, and individually calibrated. The resulting hardware includes different kinds of targets, each one covering different needs of the instrument. Standards for imaging calibration, geological samples for mineral identification and chemometric calculations or spectral references to calibrate and evaluate the health of the instrument, are all included in the SuperCam Calibration Target (SCCT). The system also includes a specifically designed assembly in which the samples are mounted. This hardware allows the targets to survive the harsh environmental conditions of the launch, cruise, landing and operation on Mars during the whole mission. Here we summarize the design, development, integration, verification and functional testing of the SCCT. This work includes some key results obtained to verify the scientific outcome of the SuperCam system.

Abstract
We report the first measurement of the neutron cross section on argon in the energy range of 100-800 MeV. The measurement was obtained with a 4.3-h exposure of the Mini-CAPTAIN detector to the WNR/LANSCE beam at LANL. The total cross section is measured from the attenuation coefficient of the neutron flux as it traverses the liquid argon volume. A set of 2631 candidate interactions is divided in bins of the neutron kinetic energy calculated from time-of-flight measurements. These interactions are reconstructed with custom-made algorithms specifically designed for the data in a time projection chamber the size of the Mini-CAPTAIN detector. The energy averaged cross section is 0.91±0.10(stat)±0.09(syst) b. A comparison of the measured cross section is made to the GEANT4 and FLUKA event generator packages, where the energy averaged cross sections in this range are 0.60 and 0.68 b, respectively.

Abstract
The pumice volcanic samples could have possible connections to the evolution of life and give us insight about their bio-geochemical processes related. In this regard, the samples from the volcanic eruption from La Restinga (El Hierro, Spain) in 2011 have been mainly studied by means of Raman spectroscopy. The research also includes analysis of XRD, Scanning Electron Microscopy and Optical Microscopy to support the Raman analysis. The results show that the Raman methods and mineral analyses are in strong agreement with the results obtained from other authors and techniques. The internal white foamy core (WFC) of the studied pumice samples shows amorphous silica, Fe-oxides, Ti-oxides, quartz, certain sulfates, carbonates, zeolites and organics. On the other hand, the external part (dark crust - DC) of these samples mainly presents primary-sequence mineralogy combined with some secondary alteration minerals such as olivine, feldspar, pyroxene, amorphous silica, and Fe-oxide. Raman spectroscopy detected other minerals not yet reported on these samples like barite, celestine and lepidocrocite. Also, the different chemometric and calibration methods for Raman spectroscopy in elemental composition, mineral classification and structural characterization has been successfully applied. From the astrobiological perspective, the research was also complemented with comparisons to other similar samples from terrestrial analogs. The main consideration was taking into account the proposed hypothesis regarding the potential behavior of the pumice as a substrate for the evolution of life. Furthermore, the detailed analysis from La Restinga eruption is coherent with the mineral phases and processes discussed from previous literature. The white internal part fulfills the conditions to work as an organic reservoir, confirmed by the detection of organic matter and selected minerals that could be used as energy sources for bacterial communities. The external layers of the samples work as a shielding layer to protect the organics from decay in extreme conditions. Finally, here we have demonstrated that the characteristics and advantages of Raman spectroscopy could help to assess and understand the possible biogenicity and alteration processes of any geological sample to be found on Mars.

Abstract
Spinal muscular atrophy (SMA) is an autosomal recessive disease caused by homozygous deletions or loss-of-function mutations in SMN1, which result in a degeneration of motor neurons in the spinal cord and brain stem. Even without a randomized placebo-controlled trial, salbutamol has been offered to patients with SMA in the neuromuscular clinics of most of hospitals for many years. We describe the response to salbutamol in 48 patients with SMA type II who were not taking any other medication. We investigate the changes over an eighteen-month period in motor functional scales and we analyze side effects and subjective response to treatment. Our results suggest that oral administration of salbutamol might be helpful in the maintenance of motor function in patients with SMA type II. An apparent beneficial effect was observed in functional scales of children under the age of 6, especially during the first 6 months of therapy. The majority of patients of all ages referred some kind of subjective positive effect associated with therapy intake. Salbutamol seemed safe and was well tolerated without serious side effects.

Abstract
Abstract
Introduction: There is evidence of variation in the patterns of treatment of older women with breast cancer (BC). As women age, there are less similarities in terms of their functional ability, physiology and social wellbeing. This multifaceted relationship between disease and ageing makes the interpretation of age-related differences in BC management and outcomes at a population level complex. Measuring frailty is as an emerging concept and offers a way to standardise how characteristics of ageing are used in BC.
Objective: We compared the primary treatment patterns of women aged ≥70yrs compared to those aged 50–69yrs, with early invasive BC (EIBC; stage 1-3A); using a novel measure of frailty in addition to commonly used patient fitness measures.
Methods: Women aged ≥50yrs, diagnosed with unilateral EIBC in England and Wales between 01/01/2014 and 31/12/2016; were identified by linkage of several national datasets. Patient fitness was measured by the reported WHO performance status (WHO PS), a calculated Charlson comorbidity score (CCS) and a developed frailty measure based on the electronic Frailty Index (eFI). Multilevel logistic regression was used to account for clustering in the data.
Results: Among 126,111 women aged ≥50yrs with BC, 88,028 had EIBC: 88% in women aged 50-69yrs and 75% in women aged ≥70yrs. Table 1 describes the proportion of women who received surgery by age and measures of fitness. Overall, older women were less likely to undergo primary surgery, regardless of fitness. For each measure of fitness, fewer women in both age groups underwent surgery as their levels of fitness decreased; the magnitude of this change was greater for women aged ≥70yrs. Older women were also less likely to receive BCS for tumours <5cm, compared to women aged 50-69yrs.

The association between independent factors of ageing and fitness, and 'no surgery' remained after accounting for case-mix differences and clustering within geographical region. Compared to women aged 50–69yrs, there was strong regional variation in the adjusted rate of surgical treatment for EIBC in women aged ≥70yrs.
Discussion: Older women are less likely to undergo surgery for EIBC. Even a minor decrease in fitness levels significantly impacts the likelihood of receiving surgery in women ≥70yrs; such a pattern is not observed in women aged 50–69yrs. Long-term follow up of these women will enable further understanding of the implications of this variability in practice on outcomes. We also acknowledge poor data completion for the WHO PS, and propose that eFI is suitable replacement measure of fitness in older patients with BC.

Abstract
Mutational profiling has demonstrated utility in predicting the likelihood of disease progression in patients with myelofibrosis (MF). However, there is limited data regarding the prognostic utility of genetic profiling in MF patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HCT). We performed high-throughput sequencing of 585 genes on pre-transplant samples from 101 patients with MF who underwent allo-HCT and evaluated the association of mutations and clinical variables with transplantation outcomes. Overall survival (OS) at 5 years post-transplantation was 52%, and relapse-free survival (RFS) was 51.1 % for this cohort. Nonrelapse mortality (NRM) accounted for most deaths. Patient's age, donor's age, donor type, and Dynamic International Prognostic Scoring System score at diagnosis did not predict for outcomes. Mutations known to be associated with increased risk of disease progression, such as ASXL1, SRSF2, IDH1/2, EZH2, and TP53, did not impact OS or RFS. The presence of U2AF1 (P = .007) or DNMT3A (P = .034) mutations was associated with worse OS. A Mutation-Enhanced International Prognostic Scoring System 70 score was available for 80 patients (79%), and there were no differences in outcomes between patients with high risk scores and those with intermediate and low risk scores. Collectively, these data identify mutational predictors of outcome in MF patients undergoing allo-HCT. These genetic biomarkers in conjunction with clinical variables may have important utility in guiding transplantation decision making.

Abstract
The neutron is the simplest nuclear system that can be used to probe the structure of the weak interaction and search for physics beyond the standard model. Measurements of neutron lifetime and β-decay correlation coefficients with precisions of 0.02% and 0.1%, respectively, would allow for stringent constraints on new physics. The UCNτ experiment uses an asymmetric magneto-gravitational UCN trap with in situ counting of surviving neutrons to measure the neutron lifetime, τn = 877.7s (0.7s)stat (+0.4/−0.2s)sys. We discuss the recent result from UCNτ, the status of ongoing data collection and analysis, and the path toward a 0.25 s measurement of the neutron lifetime with UCNτ.

Abstract
INTRODUCTION Data published in the literature about humeral resurfacing prostheses are not conclusive with good functional results but with large differences in the revision rate. The aim of our study was to evaluate the clinical and functional outcomes in patients operated at our center. MATERIAL AND METHODS Retrospective study of 19 cases in 18 patients. Follow-up of 31 (12-61) months. Surgery was indicated in cases of primary or secondary osteoarthritis. Demographic data, Constant scale, DASH questionnaire, complications and satisfaction were analyzed. Three patients were lost to follow-up due to death unrelated to surgery. RESULTS Mean age of 56 (25-80) years. Constant normalized of 73 (23-104) points. DASH questionnaire of 31 (7-84) points. Ninety four percent of the patients resumed their recreational activities and 81% sports activities. In seven cases, inferior conflict in the glenoid with varus implant was observed radiologically. There were five complications; a conservatively resolved capsulitis, three reinterventions due to symptomatic inferior glenoid usury and another to uncontrollable pain in a conservative way. Patients without rotator cuff lesion presented better scores on the functional questionnaires. All patients were satisfied with the symptomatic improvement over the previous situation and would be operated again if necessary. CONCLUSIONS The functional outcomes reported are similar to those previously published and, based on them, we believe that the resurfacing prosthesis is an option to be considered in cases of primary or secondary osteoarthritis when there is no rotator cuff injury, regardless of age.

Abstract
INTRODUCTION Identification of predictive factors of mortality in a liver transplant (LT) program optimizes patient selection and allocation of organs. OBJECTIVE To determine survival rates and predictive factors of mortality after LT in the National Liver Transplant Program of Uruguay. METHODS A retrospective study was conducted analyzing data prospectively collected into a multidisciplinary database. All patients transplanted since the beginning of the program on July 2009 to April 2017 were included (n = 148). Twenty-nine factors were analyzed through the univariate Kaplan-Meier model. A Cox regression model was used in the multivariate analysis to identify the independent prognostic factors for survival. RESULTS Overall survival was 92%, 87%, and 78% at discharge, 1 year, and 3 years, respectively. The Kaplan-Meier survival curves were significantly lower in: recipients aged >60 years, Model for End-Stage Liver Disease score >21, LT due to hepatocellular carcinoma (HCC) and acute liver failure (ALF), donors with comorbidities, intraoperative blood loss beyond the median (>2350 mL), red blood cell transfusion requirement beyond the median (>1254 mL), intraoperative complications, delay of extubation, invasive bacterial, and fungal infection after LT and stay in critical care unit >4 days. The Cox regression model (likelihood ratio test, P = 1.976 e-06) identified the following independent prognostic factors for survival: LT for HCC (hazard ratio [HR] 4.511; P = .001) and ALF (HR 6.346; P = .004), donors with comorbidities (HR 2.354; P = .041), intraoperative complications (HR 2.707; P = .027), and invasive fungal infections (HR 3.281; P = .025). CONCLUSION The survival rates of LT patients as well as the mortality-associated factors are similar to those reported in the international literature.
