Dret internacional dels drets humans en períodes de crisi: criteris d"aplicació de les obligacions jurídiques internacionals en matèria de drets econòmics, socials i culturals

L"objecte de l"article és oferir una panoràmica dels criteris d"aplicació de les obligacions jurídiques internacionals en matèria de drets econòmics, socials i culturals (DESC) en períodes de crisi. L"estudi analitza les dificultats per considerar una crisi econòmica com una situació excepcional que amenaci la vida de la nació i permeti derogar o suspendre certs drets humans; també clarificar en quina mesura és possible derogar o suspendre els DESC. La pràctica internacional, judicial i quasi-judicial ens ofereix tres criteris potencialment restrictius de la discrecionalitat estatal per repercutir negativament en el gaudi dels DESC: existència d"obligacions mínimes, no regressivitat i protecció indirecta. El seu respecte podria evitar abusos com a resultat d"una crisi i garantir la progressivitat dels DESC, tot i que la relativitat de la justiciabilitat dels DESC afegeixi una dificultat legal estructural a nivell estatal

Fragment dissolved molecular dynamics: a systematic and efficient method to locate binding sites

Diverse computational methods to support Fragment-based drug discovery (FBDD) are available in the literature. Despite their demonstrated efficacy to support FBDD campaigns, they exhibit some drawbacks such as protein denaturation or ligand aggregation that have not been yet clearly overcome in the framework of biomolecular simulations. In the present work, we discuss a systematic semi-automatic novel computational procedure, designed to surpass these difficulties. The method, named fragment dissolved Molecular Dynamics (fdMD) utilizes simulation boxes of solvated small fragments, adding a repulsive Lennard-Jones potential term to avoid aggregation, which can be easily used to solvate the targets of interest. This method has the advantage of solvating the target with a low number of ligands, thus preventing this way denaturation of the target, while simultaneously generating a database of ligandsolvated boxes that can be used in further studies. A number of scripts are made available to analyze the results and obtain the descriptors proposed as a means of trustfully discard spurious binding sites. To test our method, four Test cases of different complexity have been solvated with ligand boxes and four molecular dynamics runs of 200 ns length have been run for each system, which have been extended up to 1 µs when needed. The reported results point that the selected number of replicas are enough to identify the correct binding sites irrespective of the initial structure, even in the case of proteins having several close binding sites for the same ligand. We also propose a set of descriptors to analyze the results, among which, the average MMGBSA and the average KDEEP energies emerge as the most robust ones.Peer ReviewedPostprint (author's final draft

Fragment Dissolved molecular dynamics: A systematic and efficient method to locate binding sites.

Fragment-based drug discovery (FBDD) has been popular in the last decade, but some drawbacks, such as protein denaturation or ligand aggregation, have not yet clearly overcome in the framework of biomolecular simulations. In this work a systematic and semi-automatic method is presented as a novel proposal, named fragment dissolved Molecular Dynamics (fdMD), to improve research in future FBDD projects. Our method employs simulation boxes of solvated small fragments, adding a repulsive Lennard-Jones potential term to avoid aggregation, which can be easily used to solvate the object of interest. This method has the advantage of solvating the target with a low number of ligands, thus preventing this way denaturation of the target, while simultaneously generating a database of ligand-solvated boxes that can be used with other targets. A number of scripts are made available to analyze the results and obtain the descriptors proposed as a means of trustfully discard spurious binding sites. To test our method, four sets of different complexity have been solvated with ligand boxes and four molecular dynamics runs of 200 ns length have been run for each system, which have been extended up to 1 μs when needed. The reported results point that the selected number of replicas are enough to identify the correct binding sites irrespective of the initial structure, even in the case of proteins having several close binding sites for the same ligand. Among the proposed descriptors, average MMGBSA and average KDEEP energies emerge as the most robust ones

Interfacial chiral selection by bulk species

A chiral selection process in a self-assembled soft monolayer of an achiral amphiphile as a consequence of its interaction with chiral species dissolved in the aqueous subphase, is reported. The extent of the chiral selection is statistically measured in terms of the enantiomorphic excess of self-assembled submillimeter domains endowed with well-defined orientational chirality that is unambiguously resolved using optical microscopy. Our results show that the emergence of chirality is mediated by electrostatic interactions and significantly enhanced by hydrophobic effects. This chiral chemical effect can be suppressed and even reversed by opposing a macroscopic physical influence, such as vortical stirring. This result gives evidence for the crucial role of hydrodynamic effects in supramolecular aggregation

High Prevalence of Signs of Renal Damage Despite Normal Renal Function in a Cohort of HIV-Infected Patients: Evaluation of Associated Factors

Renal disorders are an emerging problem in HIV-infected patients. We performed a cross-sectional study of the first 1000 HIV-infected patients attended at our HIV unit who agreed to participate. We determined the frequency of renal alterations and its related risk factors. Summary statistics and logistic regression were applied. The study sample comprised 970 patients with complete data. Most were white (94%) and men (76%). Median (IQR) age was 48 (42–53) years. Hypertension was diagnosed in 19%, dyslipidemia in 27%, and diabetes mellitus in 3%. According to the Chronic Kidney Disease Epidemiology Collaboration (CKD EPI) equation, 29 patients (3%) had an eGFR < 60 ml/min/1.73m2; 18 of them (62%) presented altered albumin/creatinine and protein/creatinine (UPC or UAC) ratios. Of the patients with eGFR> 60mL/min, it was present in 293 (30%), 38 of whom (7.1%) had UPC> 300mg/g. Increased risk of renal abnormalities was correlated with hypertension (OR, 1.821 [95%CI, 1.292;2.564]; p = 0.001), age (OR, 1.015 [95%CI, 1.001;1.030], per one year; p = 0.040), and use of tenofovir disoproxil fumarate (TDF) plus protease inhibitor (PI), (OR, 1.401 [95%CI, 1.078;1.821]; p = 0.012). Current CD4 cell count was a protective factor (OR, 0.9995 [95%CI, 0.9991;0.9999], per one cell; p = 0.035). A considerable proportion of patients presented altered UPC or UAC ratios, despite having an eGFR > 60mL/min. CD4 cell count was a protective factor; age, hypertension, and use of TDF plus PIs were risk factors for renal abnormalities. Based on our results, screen of renal abnormalities should be considered in all HIV-infected patients to detect these alterations early

Impact of protease inhibitors on the evolution of urinary markers: subanalyses from an observational cross-sectional study

Kidney injury (defined as the presence of albuminuria, proteinuria, glycosuria [without hyperglycemia], hematuria, and/or renal hypophosphatemia) is an emerging problem in human immunodeficiency virus (HIV)-infected patients, although few data are available on the role of protease inhibitors (PIs) in this condition. To determine the time to kidney injury in a cohort of HIV-infected patients receiving a PI-containing regimen. We report the results of a subanalysis of a published cross-sectional study. The subanalysis included only patients receiving PI-containing regimens for more than 6 months (377 of the overall 970 patients). We determined associated factors and constructed receiver operating characteristic curves to estimate time to kidney injury depending on the PI used. The percentage of patients with kidney injury was 27.7% for darunavir, 27.9% for lopinavir, and 30% for atazanavir. Time to kidney injury was as follows: 229 days for atazanavir/ritonavir (area under the curve [AUC], 0.639; sensitivity, 0.89; specificity, 0.41); 332 days for atazanavir/ritonavir plus tenofovir (AUC, 0.603; sensitivity, 0.75; and specificity, 0.29); 318 days for nonboosted atazanavir (AUC, 0.581; sensitivity, 0.89; and specificity, 0.29); 478 days for lopinavir/ritonavir (AUC, 0.566; sensitivity, 0.864; and specificity, 0.44); 1339 days for lopinavir/ritonavir plus tenofovir (AUC, 0.667; sensitivity, 0.86; and specificity, 0.77); 283 days for darunavir/ritonavir (AUC, 0.523; sensitivity, 0.80; and specificity, 0.261); and 286 days for darunavir/ritonavir plus tenofovir (AUC, 0.446; sensitivity, 0.789; and specificity, 0.245). The use of lopinavir/ritonavir without tenofovir was a protective factor (odds ratio = 1.772; 95% CI, 1.070-2.93; P = 0.026). For all PIs, the percentage of patients with kidney injury exceeded 27%, irrespective of tenofovir use. The longest time to kidney injury was recorded with lopinavir/ritonavir. These results demonstrate the need for renal monitoring, including urine samples, in patients receiving a PI-based regimen, even when tenofovir is not used concomitantly.Peer ReviewedPostprint (published version

Influence of Regulated Deficit Irrigation on Arbequina’s Crop Yield and EVOOs Quality and Sensory Profile

Regulated deficit irrigation in super-high-density (SHD) olive orchards is a well-known strategy to save water and control plant vigor, without decreasing fruit or oil yield. As there is controversial information about its influence on virgin olive oil quality, a trial was conducted in five SHD olive orchards of Arbequina cultivar in different locations of central, east, north and northeast Spain under full irrigation (FI) and regulated deficit irrigation (RDI) treatments. RDI applied during phase II of fruit growing (40% of total needs) saves more than 20% of water on average, without reductions in olive fruit or extra virgin olive oil (EVOO) yield. No threshold of 3.5 MPa of stem water potential was crossed in any case. RDI modified sterols and the fatty acid profile of EVOOs but not phenols, quality parameters, or the sensory profile. Latitude, altitude, and yearly rainfall have a big impact on some compounds such as campesterol, oleuropein, or margaroleic or linolenic acids.info:eu-repo/semantics/publishedVersio

Anemia in patients with high-risk acute coronary syndromes admitted to Intensive Cardiac Care Units

Little information exists about the role of anemia in patients with acute coronary syndromes (ACS) admitted to Intensive Cardiac Care Units (ICCU). The aim of this study was to assess the prevalence of anemia and its impact on management and outcomes in this clinical setting. All consecutive patients admitted to eight different ICCUs with diagnosis of non-ST segment elevation ACS (NSTEACS) were prospectively included. Anemia was defined as hemoglobin < 130 g/L in men and < 120 g/L in women. The association between anemia and mortality or readmission at six months was assessed by the Cox regression method. A total of 629 patients were included. Mean age was 66.6 years. A total of 197 patients (31.3%) had anemia. Coronary angiography was performed in most patients (96.2%). Patients with anemia were significantly older, with a higher prevalence of comorbidities, poorer left ventricle ejection fraction and higher GRACE score values. Patients with anemia underwent less often coronary angiography, but underwent more often intraaortic counterpulsation, non-invasive mechanical ventilation and renal replacement therapies. Both ICCU and hospital stay were significantly longer in patients with anemia. Both the incidence of mortality (HR = 3.36, 95% CI: 1.43-7.85, P = 0.001) and the incidence of mortality/readmission were significantly higher in patients with anemia (HR = 2.80, 95% CI: 2.03-3.86, P = 0.001). After adjusting for confounders, the association between anemia and mortality/readmission remained significant (P = 0.031). Almost one of three NSTEACS patients admitted to ICCU had anemia. Most patients underwent coronary angiography. Anemia was independently associated to poorer outcomes at 6 months
