Abstract
Multiple sclerosis (MS) is unsurpassed for its clinical and pathological hetherogeneity, but the biological determinants of this variability are unknown. HLA-DRB1*15, the main genetic risk factor for MS, influences the severity and distribution of MS pathology. This study set out to unravel the molecular determinants of the heterogeneity of MS pathology in relation to HLA-DRB1*15 status. Shotgun proteomics from a discovery cohort of MS spinal cord samples segregated by HLA-DRB*15 status revealed overexpression of the extracellular matrix (ECM) proteins, biglycan, decorin, and prolargin in HLA-DRB*15-positive cases, adding to established literature on a role of ECM proteins in MS pathology that has heretofore lacked systematic pathological validation. These findings informed a neuropathological characterisation of these proteins in a large autopsy cohort of 41 MS cases (18 HLA-DRB1*15-positive and 23 HLA-DRB1*15-negative), and seven non-neurological controls on motor cortical, cervical and lumbar spinal cord tissue. Biglycan and decorin demonstrate a striking perivascular expression pattern in controls that is reduced in MS (-36.5%, p = 0.036 and - 24.7%, p = 0.039; respectively) in lesional and non-lesional areas. A concomitant increase in diffuse parenchymal accumulation of biglycan and decorin is seen in MS (p = 0.015 and p = 0.001, respectively), particularly in HLA-DRB1*15-positive cases (p = 0.007 and p = 0.046, respectively). Prolargin shows a faint parenchymal pattern in controls that is markedly increased in MS cases where a perivascular deposition pattern is observed (motor cortex +97.5%, p = 0.001; cervical cord +49.1%, p = 0.016). Our findings point to ECM proteins and the vascular interface playing a central role in MS pathology within and outside the plaque area. As ECM proteins are known potent pro-inflammatory molecules, their parenchymal accumulation may contribute to disease severity. This study brings to light novel factors that may contribute to the heterogeneity of the topographical variation of MS pathology.

Abstract
PURPOSE/OBJECTIVE(S) Biomarkers for oligometastatic disease remain elusive and few studies have attempted to correlate genomic data to the presence of true oligometastatic disease. MATERIALS/METHODS Patients with non-small cell lung cancer (NSCLC) and brain metastases were identified in our departmental database. Electronic medical records were used to identify patients for whom liquid biopsy-based comprehensive genomic profiling (Guardant Health) was available. Oligometastatic disease was defined as patients having ≤5 non-brain metastases without diffuse involvement of a single organ. Widespread disease was any spread beyond oligometastatic. Fisher's exact tests were used to identify mutations statistically associated (p<0.1) with either oligometastatic or widespread extracranial disease. A score of +1 was assigned for every mutation present associated with oligometastatic disease, and -1 was assigned for mutations associated with widespread disease. Scores were summed for each patient to create a risk score for the likelihood of oligometastatic disease, with scores subsequently correlated to the likelihood of having oligometastatic disease vs widespread disease. For oligometastatic patients, a competing risk analysis was done to assess for cumulative incidence of oligometastatic progression accounting for the potential competing risks of widespread progression of extracranial disease or death. Cox regression was used to determine the association between oligometastatic risk score and oligometastatic progression. RESULTS One hundred thirty patients met study criteria and were included in the analysis. 51 patients (39%) had oligometastatic disease. Genetic mutations included in the Guardant panel associated (p<0.1) with the presence of oligometastatic extracranial disease included ATM, JAK2, MAP2K2, and NTRK1; ARID1A and CCNE1 were associated with widespread disease. Patients with a positive, neutral and negative risk score for oligometastatic disease had a 78%, 41% and 11.5% likelihood of having oligometastatic disease, respectively (p<0.0001). Overall survival for patients with positive, neutral and negative risk scores for oligometastatic disease was 86% vs 82% vs 64% at 6 months (p = 0.2). The competing risk analysis found that the oligometastatic risk score was significantly associated with the likelihood of oligometastatic progression based on the Wald Chi-square test. Patients with positive, neutral and negative risk scores for oligometastatic disease had a cumulative incidence of oligometastatic progression of 77% vs 35% vs 33% at 6 months (p = 0.03 from competing risk model). CONCLUSION Elucidation of a genomic signature for oligometastatic disease derived from non-invasive liquid biopsy appears feasible for NSCLC patients. Patients with the oligometastatic signature exhibited higher rates of early oligometastatic progression. Validation of this signature could lead to a biomarker that has the potential to direct local therapies in oligometastatic patients.

Abstract
This study analysed the mechanisms of quinolone resistance among enterotoxigenic Escherichia coli (ETEC) in a periurban area of Lima, Peru. The susceptibility to nalidixic acid and ciprofloxacin, the role of Phe-Arg-b-Naphtylamyde inhibitable-(PAbN) efflux pumps, the presence of mutations in gyrA and parC as well as the presence of aac(6')Ib-cr, qepA, qnrA, qnrB, qnrC, qnrD, qnrVC and oqxAB were determined in 31 ETEC from previous case/control studies of children's diarrhoea. Discordances between disk diffusion, with all isolates showing intermediate or fully resistance to nalidixic acid, and minimal inhibitory concentration (MIC), with 7 isolates being below considered resistance breakpoint, were observed. Twenty-one isolates possessed gyrA mutations (19 S83L, 2 S83A). AAC(6') Ib-cr, QnrS, QnrB and QepA were found in 7, 6, 2 and 1 isolates respectively, with 3 isolates presenting 2 transferable mechanisms of quinolone resistance (TMQR) concomitantly. TMQR were more frequent among isolates with MIC to nalidixic acid ranging from 2 to 16 mg/L (p=0.03), while gyrA mutations were more frequent among isolates with nalidixic acid MIC >= 128 mg/L (p=0.0002). In summary, the mechanisms of quinolone resistance present in ETEC isolates in Peru have been described. Differences in the prevalence of underlying mechanisms associated with final MIC levels were observed. The results suggest two different evolutive strategies to survive in the presence of quinolones related to specific bacterial genetic background.

Abstract
BACKGROUND The use of allogeneic stem cell transplantation (allo-SCT) for the treatment of hematologic diseases is steadily increasing. However, allo-SCT has the downside of causing considerable treatment-related morbidity and mortality. Mobile technology applied to healthcare (mHealth) has proven to be a cost-effective strategy to improve care and offer new services to people with multimorbidity, but there are few data on its usefulness in allo-SCT recipients. OBJECTIVE The aim of this report was to describe a new integrated healthcare model facilitated by an mHealth platform, named EMMASalud-MY-Medula, and to report the results of a le. STUDY DESIGN The MY-Medula platform development approach consisted of 4 phases. Firstly, patient and healthcare professional needs were identified and technological development and pre-testing tests were conducted (phases 1-3, January 2016-March 2021). Then, a non-randomized, prospective, observational, single-center pilot study was conducted (October 2021-January 2022) at the adult Stem Cell Transplant Unit of a tertiary university hospital. RESULTS Twenty-eight volunteer allo-SCT recipients were included in the pilot study. Fifty percent were outpatients in the first-year post-SCT and the remaining 50% were affected by steroid-dependent graft-versus-host disease (SR-GVHD). All patients used MY-Medula application during the two-month follow-up period with a median number of visits to the application of 143 (range 6-477). A total of 2067 self-monitoring records were made, and 205 text messages were received, most of them related to symptoms description (47%) and doubts about medication (21%). In 3.4% of the cases drug dose adjustments were performed by the pharmacist because of dosing errors or interactions. At the end of the study, a 6-question Likert-type questionnaire for patients and a 22-question test for healthcare professionals showed a high degree of satisfaction (95% and 100% respectively) with the new healthcare pathway. CONCLUSIONS Re-engineering allo-SCT recipients follow-up into an integrated, multidisciplinary model of care facilitated by mHealth tools is feasible and has been associated with a high usability and degree of satisfaction by patients and healthcare professionals. A randomized trial aiming to determine the cost-effectiveness of MY-Medula-based follow-up post-SCT is currently enrolling participants.

Abstract
Introduction SARS-CoV-2, responsible for COVID-19, is a pandemic that has taken the world by storm. We present the only contemporary reported case of COVID-19 myocarditis leading to recovery with utilization of biventricular impella for temporary mechanical circulatory support. No cases have been reported regarding utilization of Bi-V impella as therapy for management of SARS-CoV-2.. Case Report We present a 35 year old-woman with history of systemic sclerosis who was found to have 5 days of generalized malaise associated with fevers and cough. On arrival she was found tachycardic at 112 bpm and febrile 101.8 F. She tested positive for COVID-19 via nasal CPR. Cardiac enzymes were found elevated on admission with troponin T elevated at 0.28. On day two of hospitalization patient had spontaneous PEA arrest secondary to hypoxemia. Transthoracic echocardiogram(TTE) revealed EF <10% and RV impairment which compare to prior which had normal ejection fraction. Labs showed elevated lactic acidosis of 10. Invasive hemodynamics assessment RA 21 mmHg, PA 32/23(mean 26 mmHg) and PCWP 18 mmHg. Calculated PAPi 0.76, CO 2.1 L/min and CI of 1.2 L/min/m^2. Decision was made to place right and left sided ventricular impellas for mechanical circulatory support. She was started on IVIG for COVID-19 myocarditis along with remdesivir and solumedrol. After two weeks of continuous temporary mechanical circulatory support(TMCS), patient hemodynamics improved and she was able to be weaned from her need for TMCS. Repeat echocardiogram demonstrated recovery and remodeling with an LVEF of 60% and no significant valvular disease. She was discharge home at day 23 with no neurological deficit. Summary The use of biventricular continuous microaxial flow devices during acute COVID-19 myocarditis is key to allow ventricular rest and optimal offloading without the increased risk of surgically placed TMCS such as Centrimag or VA or VV ECMO. With recent emergency use by the FDA, its wide adaptation remains sparse. Our case demonstrates a unique approach to management of COVID-19 myocarditis. It is the only reported case in the literature utilizing biventricular Impella devices for circulatory support without the concurrent use of ECMO. Due to the success in this patient, this promising approach warrants continued investigation in the management of COVID myocarditis and cardiogenic shock.

Abstract
To exploit the hydrolytic activity and high selectivity of immobilized lipase B from Candida antarctica on octyl agarose (CALB-OC) in the hydrolysis of triacetin and also to produce new value-added compounds from glycerol, this work describes a chemoenzymatic methodology for the synthesis of the new dimeric glycerol ester 3-((2,3-diacetoxypropanoyl)oxy)propane-1,2-diyl diacetate. According to this approach, triacetin was regioselectively hydrolyzed to 1,2-diacetin with CALB-OC. The diglyceride product was subsequently oxidized with pyridinium chlorochromate (PCC) and a dimeric ester was isolated as the only product. It was found that the medium acidity during the PCC treatment and a high 1,2-diacetin concentration favored the formation of the ester. The synthesized compounds were characterized using IR, MS, HR-MS, and NMR techniques. The obtained dimeric ester was evaluated at 100 ppm against seven bacterial strains and two Candida species to identify its antimicrobial activity. The compound has no inhibitory activity against the bacterial strains used but decreased C. albicans and C. parapsilosis growth by 49% and 68%, respectively. Hemolytic activity was evaluated, and the results obtained support the use of the dimeric ester to control C. albicans and C. parapsilosis growth in non-intravenous applications because the compound shows hemolytic activity.

Abstract
Background: The "Habsburg jaw" has long been associated with inbreeding due to the high prevalence of consanguineous marriages in the Habsburg dynasty. However, it is thought that mandibular prognathism (MP) is under the influence of a dominant major gene.Aim: To investigate the relationship between the "Habsburg jaw" and the pedigree-based inbreeding coefficient (F) as a relative measure of genome homozygosity.Subjects and methods: The degree of MP and maxillary deficiency (MD) of 15 members of the Habsburg dynasty was quantified through the clinical analysis of 18 dysmorphic features diagnosed from 66 portraits.Results: A statistically significant correlation (r = 0.711, p = 0.003) between MP and MD was observed among individuals. Only MP showed a statistically significant positive regression on F as evidenced from univariate analysis (b = 6.36 ± 3.34, p = 0.040) and multivariate analysis (PCA) performed from single dysmorphic features (b = 14.10 ± 6.62, p = 0.027, for the first PC).Conclusion: Both MP and MD are generally involved in the "Habsburg jaw." The results showed a greater sensitivity to inbreeding for the lower third of the face and suggest a positive association between the "Habsburg jaw" and homozygosity and therefore a basically recessive inheritance pattern.

Abstract
Abstract
Background
There is scarce evidence about the prevalence and clinical relevance of moderate to severe valvular heart disease (VHD) in survivors of out of hospital cardiac arrest (OHCA).
Purpose
To determine whether VHD influence prognosis of OHCA survivors.
Methods
All consecutive patients admitted to the Acute Cardiac Care Unit after OHCA and surviving until hospital discharge were included. All patients received targeted-temperature management according to our local protocol. Univariate and multivariate Cox-proportional hazard models were employed.
Results
A total of 201 patients were included in the analysis. Mean age was 57.6±14.2 years and 168 (83.6%) were male. Eighteen patients (9.0%) had moderate or severe VHD during index admission (Table 1). Patients with VHD were less frequently of male sex, [11 (61.1%) vs 157 (85.8%), p=0.014], experienced less acute coronary syndrome-related arrhytmias [2 (11.1%) vs 85 (46.5%), p=0.005], and had a lower pH at hospital admission (6.9±1.6 vs 7.2±0.15, p=0.008). During a median follow-up of 40.3 (18.9–69.1) months, patients with VHD showed higher mortality [7 (38.9%) vs 28 (15.3%), p=0.004] and more heart failure-related admissions [7 (38.9%) vs 15 (8.2%), p<0.001]. Only five patients received surgical or percutaneous treatment for VHD during follow-up, with no deaths in this subgroup. Moderate or severe VHD proved to be an independent predictor of global cardiovascular events and specifically heart failure episodes (Figure 1).
Table1 Variable With valvular disease Without valvular disease p value Age, mean±DS, years 63.5±13.2 57.0±14.1 0.066 Hypertension, n (%) 12 (66.7) 95 (51.9) 0.231 Diabetes, n (%) 5 (27.8) 24 (13.1) 0.149 Dyslipidaemia, n (%) 7 (38.9) 79 (43.2) 0.726 Smokin habit, n (%) 4 (22.2) 90 (49.2) 0.045 Witnessed cardiac arrest, n (%) 18 (100) 175 (95.6) 1.000 Time from CA to ROSC, mean±DS, minute 19.1±7.5 21.2±13.1 0.506 Shockable rhythm, n (%) 13 (72.2) 163 (89.1) 0.055 LVEF at hospital discharge (%) 42.8±12.1 46.9±14.6 0.254
Figure 1
Conclusion
The presence of significant VHD in survivors after OHCA is a predictor of poor outcomes. Specific management of VHD may be specially relevant in this high-risk patients and guideline-oriented therapy, including surgery and percutaneous intervention should be encouraged when indicated.

Abstract
The use of commercial yeast strains is a common practice in winemaking leading to a predictable quality in wine production, avoiding stuck or sluggish fermentations. However, the use of commercial yeasts leads to a consequent reduction in autochthonous microbial diversity. In this study, 1047 isolates from three Spanish appellations of origin were checked for fingerprinting on interdelta polymorphisms and the strain composition and diversity analysed using an extensible open-source platform for processing and analysis of an in-house polymorphism database developed for this study. Ancient vineyards managed with organic practices showed intermediate to low levels of strains diversity indicating the existence of stable populations of Saccharomyces cerevisiae strains. A drastic reduction in the number of different S. cerevisiae strains was observed in vineyards with cellars using a selected autochthonous S. cerevisiae strain for winemaking. Contrary, the use of allochthonous commercial strains in wineries did not seem to affect the native S. cerevisiae strain composition and diversity. SIGNIFICANCE AND IMPACT OF THE STUDY: The aim of this study was to compare different viticulture and oenological practices to determine their influence on the composition and diversity of Saccharomyces cerevisiae strains in wine fermentations. The study shows that the use of autochthonous strains of S. cerevisiae as starters for wine fermentation could have an important incidence on S. cerevisiae strains diversity in surrounding vineyards. The use of autochthonous strains of S. cerevisiae reduced the detected number of S. cerevisiae strains, a fact that was not observed when allochthonous commercial strains were used. Furthermore, vineyards managed with organic practices showed intermediate to low levels of S. cerevisiae strain diversity, whereas conventional practices showed higher levels.

Abstract
OBJECTIVE The task force of the International Conference of Frailty and Sarcopenia Research (ICFSR) developed these clinical practice guidelines to overview the current evidence-base and to provide recommendations for the identification and management of frailty in older adults. METHODS These recommendations were formed using the GRADE approach, which ranked the strength and certainty (quality) of the supporting evidence behind each recommendation. Where the evidence-base was limited or of low quality, Consensus Based Recommendations (CBRs) were formulated. The recommendations focus on the clinical and practical aspects of care for older people with frailty, and promote person-centred care. Recommendations for Screening and Assessment: The task force recommends that health practitioners case identify/screen all older adults for frailty using a validated instrument suitable for the specific setting or context (strong recommendation). Ideally, the screening instrument should exclude disability as part of the screening process. For individuals screened as positive for frailty, a more comprehensive clinical assessment should be performed to identify signs and underlying mechanisms of frailty (strong recommendation). Recommendations for Management: A comprehensive care plan for frailty should address polypharmacy (whether rational or nonrational), the management of sarcopenia, the treatable causes of weight loss, and the causes of exhaustion (depression, anaemia, hypotension, hypothyroidism, and B12 deficiency) (strong recommendation). All persons with frailty should receive social support as needed to address unmet needs and encourage adherence to a comprehensive care plan (strong recommendation). First-line therapy for the management of frailty should include a multi-component physical activity programme with a resistance-based training component (strong recommendation). Protein/caloric supplementation is recommended when weight loss or undernutrition are present (conditional recommendation). No recommendation was given for systematic additional therapies such as cognitive therapy, problem-solving therapy, vitamin D supplementation, and hormone-based treatment. Pharmacological treatment as presently available is not recommended therapy for the treatment of frailty.

Abstract
The Priorat and Montsant Appellations of Origin are considered to produce some of the finest wines in the Mediterranean area of Spain. Located in the south of Catalonia (North-East Spain), they account for close to 4000 ha cultivated by more than 1300 vine growers under severe Mediterranean climatic conditions and hence threatened by global warming. In this context, sustainable practices are needed for the optimal use of natural resources in order to ensure the durability of high-quality wine production in the region. In addition, these practices allow this region to maintain high levels of biodiversity, a major characteristic of Priorat and Montsant's agricultural landscape, which represents an important touristic attraction. The Project LIFE Priorant+Montsant, funded by the European Union, proposed the implementation of sustainable practices at a regional scale, in order to achieve remarkable reductions of resource consumption in three axes: 1) Irrigation water management, 2) vine fertilization and 3) synthetic pesticide use. Reductions are achieved by providing the necessary technical support to growers to adopt practices, developing optimized strategies and evaluating the viticulture and winery production processes. After the two first seasons of the project, 2017 and 2018, the objectives of reduction of resources consumption have been successfully achieved. A total of 53 vineyard plots, representing the main grape varieties in the region (Grenache, Carignan, Cabernet Sauvignon and Syrah) were classified in eight sub-areas and monitored for water consumption. From pea-size to harvest (phenological stages), weekly measurements of phenology, water potential and meteorological data were collected. Irrigation recommendations were then given to growers, to avoid water potential below − 1.4 MPa. Overall, more than 50 irrigation recommendations were emitted to growers. The water consumption with the optimized irrigation strategy ranged from 10 to 63 litres per ha, the recommended dose saved 20 to 87% of the irrigation water per year, according to previous general recommendations in this region. Regarding fertilization, soil samples were provided by growers and leave samples were taken from vineyards to assess nutrient levels and develop the corresponding recommendation of fertilization, depending on the analysis results. The analyzed soil samples from the different sub-areas were grouped by the Principal Component Analysis, in which the first and second principal components accounted for 31.6% and 11.8% of the variability and were related to soil texture and nutrient content of soils, respectively. Overall, the recommended doses of organic fertilizers saved more than 20% of the usual chemical fertilizer application in the region. The reduction of pesticide use will be achieved through three actions related to three main pests and diseases of grapevine: optimized formulations against powdery mildew, alternative products to reduce copper use against downy mildew and, increase of surface under mating disruption strategy against grape berry moth Lobesia botrana. Before implementing these actions, no vineyards were managed under mating disruption in the Montsant area and 207 ha have been monitored in 2018 after two years. In the Priorat area, more than 200 ha have also adopted this strategy during the project. This action has saved more than 500 application doses of synthetic insecticides in those vineyards. Within the same scope, several formulations will be proved in the following years in order to assess their effectiveness against powdery and downy mildew in further specific field trials. Candidate products will be introduced in Integrated Pest Management strategies to achieve the desired pesticide reduction levels. The results will represent specific regional strategies for irrigation, fertilization and plant protection, and are extensible to most of the vineyards in Priorat and Montsant, as well as to other vitivinicultural regions which similar conditions.

Abstract
BACKGROUND The increasing age in the industrialized countries places significant demands on intensive care unit (ICU) resources and this triggers debates about end-of-life care for the elderly. OBJECTIVES We sought to determine the impact of age on the decision-making process to limit or withdraw life-sustaining treatment (DWLST) in an ICU in France. We hypothesized that there are differences in the decision-making process for young and old patients. DESIGN, SETTING, PARTICIPANTS We prospectively studied end-of-life decision-making for all consecutive admissions (n=390) to a tertiary care university ICU in Toulouse, France over a period of 11 months between January and October 2011. RESULTS Among the 390 patients included in the study (age ≥70yo, n=95; age <70yo, n=295) DWLST were more common for patients 70 years or older (43% for age ≥70yo vs. 16% for age <70yo, p <0.0001). Reasons for DWLST were different in the 2 groups, with the 'no alternative treatment options' and 'severity of illness' as the most frequent reasons cited for the younger group whereas it was 'severity of illness' for the older group. 'Advanced age' led to DWLSTs in 43% of the decisions in the group ≥70yo (vs. 0% in the group <70yo, p <0.0001). Multivariate logistic regression showed a high SAPS II score and age ≥70yo as independent risk factors for DWLSTs in the ICU. We did not find age ≥70yo as an independent risk factor for mortality in ICU. CONCLUSION We found that age ≥70yo was an independent risk factor for DWLSTs for patients in the ICU, but not for their mortality. Reasons leading to DWLSTs are different according to the age of patients.

Abstract
Background RAS assessment is mandatory for therapy decision in metastatic colorectal cancer (mCRC) patients. This determination is based on tumor tissue, however, genotyping of circulating tumor (ct)DNA offers clear advantages as a minimally invasive method that represents tumor heterogeneity. Our study aims to evaluate the use of ctDNA as an alternative for determining baseline RAS status and subsequent monitoring of RAS mutations during therapy as a component of routine clinical practice. Patients and methods RAS mutational status in plasma was evaluated in mCRC patients by OncoBEAM™ RAS CRC assay. Concordance of results in plasma and tissue was retrospectively evaluated. RAS mutations were also prospectively monitored in longitudinal plasma samples from selected patients. Results Analysis of RAS in tissue and plasma samples from 115 mCRC patients showed a 93% overall agreement. Plasma/tissue RAS discrepancies were mainly explained by spatial and temporal tumor heterogeneity. Analysis of clinico-pathological features showed that the site of metastasis (i.e. peritoneal, lung), the histology of the tumor (i.e. mucinous) and administration of treatment previous to blood collection negatively impacted the detection of RAS in ctDNA. In patients with baseline mutant RAS tumors treated with chemotherapy/antiangiogenic, longitudinal analysis of RAS ctDNA mirrored response to treatment, being an early predictor of response. In patients RAS wt, longitudinal monitoring of RAS ctDNA revealed that OncoBEAM was useful to detect emergence of RAS mutations during anti-EGFR treatment. Conclusion The high overall agreement in RAS mutational assessment between plasma and tissue supports blood-based testing with OncoBEAM™ as a viable alternative for genotyping RAS of mCRC patients in routine clinical practice. Our study describes practical clinico-pathological specifications to optimize RAS ctDNA determination. Moreover, OncoBEAM™ is useful to monitor RAS in patients undergoing systemic therapy to detect resistance and evaluate the efficacy of particular treatments.

Abstract
Summary
Aim: To determine the long-term prognostic value of SPECT myocardial perfusion imaging (MPI) for the occurrence of cardiovascular events in diabetic patients. Patients, methods: SPECT MPI of 210 consecutive Caucasian diabetic patients were analysed using Kaplan-Meier event-free survival curves and independent predictors were determined by Cox multivariate analyses. Results: Follow-up was complete in 200 (95%) patients with a median period of 3.0 years (0.8-5.0). The population was composed of 114 (57%) men, age 65 ±10 years, 181 (90.5%) type 2 diabetes mellitus, 50 (25%) with a history of coronary artery disease (CAD) and 98 (49%) presenting chest pain prior to MPI. The prevalence of abnormal MPI was 58%. Patients with a normal MPI had neither cardiac death, nor myocardial infarction, independently of a history of coronary artery disease or chest pain. Among the independent predictors of cardiac death and myocardial infarction, the strongest was abnormal MPI (p <0.0001), followed by history of CAD (Hazard Ratio (HR)=15.9; p=0.0001), diabetic retinopathy (HR=10.0; p=0.001) and inability to exercise (HR=7.7; p=0.02). Patients with normal MPI had a low revascularisation rate of 2.4% during the followup period. Compared to normal MPI, cardiovascular events increased 5.2 fold for reversible defects, 8.5 fold for fixed defects and 20.1 fold for the association of both defects. Conclusion: Diabetic patients with normal MPI had an excellent prognosis independently of history of CAD. On the opposite, an abnormal MPI led to a >5-fold increase in cardiovascular events. This emphasizes the value of SPECT MPI in predicting and risk-stratifying cardiovascular events in diabetic patients.

Abstract
Among all novel challenges nowadays worldwide, infectious disease is probably one of the most important. It is well-known that common treatments used include high doses of antibiotics, which are very invasive therapies for patients. These treatments are more intensive when the infection is related to multidrug resistant microorganisms. In this sense, in this work we report the use of reverse micelles to form less than 5 nm gold, silver, and gold-silver nanoparticles (NPs) with biological activity against five opportunistic Candida strains responsible of several diseases in human beings. As a result, we evaluate the interface properties and droplet-droplet interactions of micelles founding high fluidity in the polar head of the surfactant, necessary to form a flexible interaction channel in the "dimmer" micelle-micelle. In this condition, we form monodispersed, highly reactive NPs with sizes less than 5 nm with high antifungal activity against C. parapsilosis, C. Krusei, C. glabrata, C. guillermondii, and C. albicans, with minimum inhibitory concentrations (MIC50) less than 0.7 ppm in all cases, the lowest reported to the best of our knowledge. These are very promising results to develop alternative therapies to treat fungal diseases in humans, animals, and plants, or to coat conventional surfaces in surgery rooms.

Abstract
Aims and MethodThe ability of routine clinical practice to detect drug use at acute psychiatric admission was assessed by comparing the results of urinalysis with information on drug use extracted from patient records (n=112).ResultsUrinalysis detected drug use in 23% of the sample. Cannabis was the drug most frequently found. Of the cases of drug use positively identified by urinalysis, 54% were not identified in the notes. Some information on drug use proximal to admission was found in 40% of patient records. Patients asked about proximal drug use were younger than those not asked.Clinical ImplicationsAll patients should be asked about drug use.

Abstract
OBJECTIVES Sarcopenia, defined as an age-associated loss of skeletal muscle function and muscle mass, occurs in approximately 6 - 22 % of older adults. This paper presents evidence-based clinical practice guidelines for screening, diagnosis and management of sarcopenia from the task force of the International Conference on Sarcopenia and Frailty Research (ICSFR). METHODS To develop the guidelines, we drew upon the best available evidence from two systematic reviews paired with consensus statements by international working groups on sarcopenia. Eight topics were selected for the recommendations: (i) defining sarcopenia; (ii) screening and diagnosis; (iii) physical activity prescription; (iv) protein supplementation; (v) vitamin D supplementation; (vi) anabolic hormone prescription; (vii) medications under development; and (viii) research. The ICSFR task force evaluated the evidence behind each topic including the quality of evidence, the benefit-harm balance of treatment, patient preferences/values, and cost-effectiveness. Recommendations were graded as either strong or conditional (weak) as per the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Consensus was achieved via one face-to-face workshop and a modified Delphi process. RECOMMENDATIONS We make a conditional recommendation for the use of an internationally accepted measurement tool for the diagnosis of sarcopenia including the EWGSOP and FNIH definitions, and advocate for rapid screening using gait speed or the SARC-F. To treat sarcopenia, we strongly recommend the prescription of resistance-based physical activity, and conditionally recommend protein supplementation/a protein-rich diet. No recommendation is given for Vitamin D supplementation or for anabolic hormone prescription. There is a lack of robust evidence to assess the strength of other treatment options.

Abstract
Cooling tower emissions have become an increasingly common hazard to the environment (air polluting, ice formation and salts deposition) and to the health (Legionella disease) in the last decades. Several environmental policies have emerged in recent years limiting cooling tower emissions but they have not prevented an increasing intensity of outbreaks. Since the level of emissions depends mainly on cooling tower component design and the operating conditions, this paper deals with an experimental investigation of the amount of emissions, drift and PM10, emitted by a cooling tower with different configurations (drift eliminators and distribution systems) and working under several operating conditions. This objective is met by the measurement of cooling tower source emission parameters by means of the sensitive paper technique. Secondary objectives were to contextualize the observed emission rates according to international regulations. Our measurements showed that the drift rates included in the relevant international standards are significantly higher than the obtained results (an average of 100 times higher) and hence, the environmental problems may occur. Therefore, a revision of the standards is recommended with the aim of reducing the environmental and human health impact. By changing the operating conditions and the distribution system, emissions can be reduced by 52.03% and 82% on average. In the case of drift eliminators, the difference ranges from 18.18% to 98.43% on average. As the emissions level is clearly influenced by operating conditions and components, regulation tests should be referred to default conditions. Finally, guidelines to perform emission tests and a selection criterion of components and conditions for the tested cooling tower are proposed.
