Abstract
BACKGROUND AND OBJECTIVE The treatment of psoriasis should not only focus on skin affectations but also weigh the parameters for health-related quality of life (HRQoL), thereby tackling the concept of cumulative life course impairment (CLCI) and treating the patient from a holistic perspective. The CRYSTAL study aimed to characterize psoriasis with real-word data from Spanish clinical practice in patients with moderate to severe disease who received continuous systemic treatment for at least 24 weeks by using the absolute Psoriasis Area and Severity Index (PASI) score and its correlation to HRQoL. MATERIAL AND METHODS This was a non-interventional, cross-sectional study conducted in 30 centers in Spain, with 301 patients between the ages of 18 and 75 years. The study collected data regarding current treatment and absolute PASI and their relationship to HRQoL using the Dermatology Life Quality Index (DLQI), to activity impairment using the Work Productivity and Activity Impairment (WPAI) questionnaire, and to treatment satisfaction. RESULTS The mean (SD) age was 50.5 (12.5) years, with a duration of disease of 14 (14.1) years. The mean (SD) absolute PASI reported was 2.3 (3.5), with 28.7% of patients presenting with PASI from >1 to ≤3 and 22.6% with PASI>3. Higher PASI scores were associated with higher DLQI (p<0.001) and WPAI scores and lower levels of treatment satisfaction (p<0.001). CONCLUSIONS These data indicate that achieving lower absolute PASI values may correlate not only with better HRQoL but also with better work productivity and treatment satisfaction.

Abstract
Reticular materials constructed from regular molecular building blocks (MBBs) have been widely explored in the past three decades. Recently, there has been increasing interest in the assembly of novel, intricate materials using less-symmetric ligands; however, current methods for predicting structure are not amenable to this increased complexity. To address this gap, we propose herein a generalised version of the net-clipping approach for anticipating the topology of metal-organic frameworks (MOFs) assembled from organic linkers and different polygonal and polyhedral MBBs. It relies on the generation of less-symmetric nets with less-connected linkers, via the rational deconstruction of more-symmetric and more-connected linkers in edge-transitive nets. We applied our top-down strategy to edge-transitive nets containing 4-c tetrahedral, 6-c hexagonal, 8-c cubic or 12-c hexagonal prism linkers, envisaging the formation of 102 derived and 46 clipped nets. Among these, we report 33 new derived nets (icn7-icn39) and 6 new clipped nets (icn1-icn6). Importantly, the feasibility of using net-clipping to anticipate clipped nets is supported by literature examples and new experimental additions. Finally, we suggest and illustrate that net-clipping can be extended to less-regular, non-edge transitive nets as well as to covalent-organic frameworks (COFs), thus opening new avenues for the rational design of new reticular materials exhibiting unprecedented topologies.

Abstract
A novel procedure for the synthesis of α,α-diaryl-α-amino acid derivatives has been developed. Silver oxide catalyzes the conjugate addition of α-aryl isocyanoacetates to o-quinone diimide, affording the corresponding α,α-diarylisocyano esters in excellent yields and regioselectivities in short reaction times. Acid hydrolysis of the isocyano group provides the corresponding amino acids bearing a diarylated tetrasubstituted carbon atom. The reaction is also amenable to the synthesis of α-alkyl-α-arylisocyano esters, while the reaction with 3-hydroxy o-quinone diimides provides 4H-benzo[e][1,3]oxazines via a conjugate addition/cyclization process.

Abstract
A diastereo- and enantioselective organocatalytic aldol reaction between alkylidenepyrazolones and trifluoromethyl ketones leading to chiral tertiary alcohols bearing a trifluoromethyl group is presented. The methodology is based on the use of a bifunctional organocatalyst in order to activate the γ-hydrogen atoms of the alkylidenepyrazolone nucleophile and the carbonyl group of the trifluoromethylarylketone providing highly functionalized trifluoromethyl alcohols with moderate yields, excellent diastereoselectivity, and moderate to good enantioselectivity. Experiments monitoring the conversion by 1H NMR and the enantiomeric excess by HPLC with the reaction time showed that full conversion of the starting materials is not achieved and that the enantiomeric excess decreases upon extended times, probably due to the reversibility of the reaction.

Vine shoots were subjected to a mild aqueous extraction (to remove water-soluble extractives), and the extracted solids were reacted in catalyzed media (containing water and 1-butanol) to achieve the one-stage solubilization of lignin and hemicelluloses, yielding a cellulose-rich solid. Operating in a microwave-heated reactor under optimized conditions (190 °C in media containing 2% of catalyst and 52% 1-butanol), 67.8% lignin was dissolved, and solids containing 75% cellulose were obtained. Lignin was recovered from the reaction medium and characterized, whereas the hemicellulose-derived products present in the aqueous phase (obtained under conditions leading to maximum concentrations of 17.7 g pentoses/L) were converted into furfural at 64.6% molar yield by acidic processing in the presence of recycled 1-butanol.

Abstract
Background COVID-19 is primarily a respiratory disease; however, there is also evidence that it causes endothelial damage in the microvasculature of several organs. The aim of the present study is to characterize in vivo the microvascular reactivity in peripheral skeletal muscle of severe COVID-19 patients. Methods This is a prospective observational study carried out in Spain, Mexico and Brazil. Healthy subjects and severe COVID-19 patients admitted to the intermediate respiratory (IRCU) and intensive care units (ICU) due to hypoxemia were studied. Local tissue/blood oxygen saturation (StO2) and local hemoglobin concentration (THC) were non-invasively measured on the forearm by near-infrared spectroscopy (NIRS). A vascular occlusion test (VOT), a three-minute induced ischemia, was performed in order to obtain dynamic StO2 parameters: deoxygenation rate (DeO2), reoxygenation rate (ReO2), and hyperemic response (HAUC). In COVID-19 patients, the severity of ARDS was evaluated by the ratio between peripheral arterial oxygen saturation (SpO2) and the fraction of inspired oxygen (FiO2) (SF ratio). Results Healthy controls (32) and COVID-19 patients (73) were studied. Baseline StO2 and THC did not differ between the two groups. Dynamic VOT-derived parameters were significantly impaired in COVID-19 patients showing lower metabolic rate (DeO2) and diminished endothelial reactivity. At enrollment, most COVID-19 patients were receiving invasive mechanical ventilation (MV) (53%) or high-flow nasal cannula support (32%). Patients on MV were also receiving sedative agents (100%) and vasopressors (29%). Baseline StO2 and DeO2 negatively correlated with SF ratio, while ReO2 showed a positive correlation with SF ratio. There were significant differences in baseline StO2 and ReO2 among the different ARDS groups according to SF ratio, but not among different respiratory support therapies. Conclusion Patients with severe COVID-19 show systemic microcirculatory alterations suggestive of endothelial dysfunction, and these alterations are associated with the severity of ARDS. Further evaluation is needed to determine whether these observations have prognostic implications. These results represent interim findings of the ongoing HEMOCOVID-19 trial. Trial registration ClinicalTrials.gov NCT04689477. Retrospectively registered 30 December 2020.

Abstract
Throughout history there have been epidemics and pandemics of all kinds, however the most recent ones have been respiratory diseases that have had a significant effect on the society and that have caused high mortality rates. The preventive measures to minimize the risk of contagion by contact with infected surfaces include ergonomic accessories including personal protective equipment (PPE) to prevent hands to be in contact with surfaces that could be infected by viruses, bacteria, fungi, etc., thus avoiding infection by the usual entry routes (mouth, nose, and eyes) to the human body of highly contagious diseases such as COVID-19. The collaborative manufacture of these safety accessories at the site of consumption is a current option that minimizes infectious diseases and reduces costs. Accessories such as the so-called “ear saver” and “anti-contact keys” can be produced by 3D printing with a general CAD/CAM and allow users in hospitals, and schools, such as medical and teaching staff and society in general to extend the life of N95 respirator fasteners (protective masks) and avoid contagion. These devices can be used to open doors and windows and control elevators, etc. The accessories can be optimized ergonomically for individual use by providing a custom design. The collaborative manufacture of these elements allows the product design stages to be carried out autonomously. In the manufacturing stage, 3D printers can be used to produce the devices at the point of use, thus saving on transport and distribution costs. This paper describes a comparative analysis of their design, manufacture and use in hospitals, schools, universities, and commercial areas with the aim of improving the current design.

Abstract
Naphthols, hydroxyindoles and an activated phenol are reacted with differently substituted (E)-nitrobut-1-en-3-ynes using the commercially available Rawal's chiral squaramide. The corresponding β-nitroalkynes were obtained with good yields and excellent enantioselectivities. Moreover, dihydronaphthofurans can be accessed via silver catalysed cyclization in a tandem one-pot procedure, with high preservation of the optical purity.

Abstract
The development of new prebiotics capable of modulating the gut microbiota in the elderly has become an area of great interest due to the particular vulnerability and frailty of this population. In the present work, mixtures of pectin-derived oligosaccharides (POS) were manufactured from lemon peel waste and evaluated for their capability to modulate the gut microbiota using, as inoculum, a pool of faeces from elderly donors. Both changes in the microbiota and the metabolic activity were assessed and compared with commercial fructooligosaccharides (FOS) and the standard ileal efflux medium (SIEM) using the TIM-2 in vitro colon model. POS fermentation led to similar or even better effects than FOS at phylum, family and genus levels. Higher increments in beneficial species such as Faecalibacterium prausnitzii and larger alpha diversity values were observed with POS in comparison with FOS and in some cases with SIEM. The PCoA analyses revealed that the microbial profiles resulting from POS and FOS bacterial fermentation were rather similar and differed from those observed after SIEM fermentation. Finally, although butyrate cumulative production was comparable among substrates, the highest short chain fatty acid (SCFA) and the lowest branched chain fatty acid (BCFA) cumulative production was observed in POS experiments. These results support the potential of pectin-derived oligosaccharides as prebiotic candidates targeting gut health in the elderly.

Abstract
Mixtures of xylooligosaccharides (XOS) were manufactured from Eucalyptus nitens samples by hydrothermal processing. In order to obtain a product suitable to be used as a prebiotic, the liquors obtained were subjected to a refining sequence consisting of a two-step membrane filtration followed by anion exchange and freeze-drying. The process proposed allowed to obtain a highly refined product mainly made up of a mixture of substituted XOS with a degree of polymerization, DP3–10, which was evaluated for its prebiotic potential by in vitro fermentation assays. Their effects on the microbiota composition and the metabolic activity were assessed along the fermentation time and compared to fructooligosaccharides (FOS, a gold standard prebiotic), using fecal inocula from donors belonging to two age-groups (young and elderly). Significant and similar increases were observed in most of the bacterial groups considered (including Bifidobacterium spp. or several butyrate-producers) in both XOS and FOS in vitro interventions, although XOS resulted in significantly higher increases in total bacteria and lower rises in Clostridium clusters I and II than FOS. Regarding the metabolic activity, higher amounts of total organic acid (TOA; 150 vs. 110 mM) and higher total short-chain fatty acid (SCFA)/TOA ratio (0.88 vs. 0.70 mol/mol) were achieved at 28 h using XOS as a carbon source in comparison with FOS. Moreover, both substrates resulted in different metabolite profiles. Higher percentages of acetate and propionate were achieved when XOS were used as substrates, whereas FOS resulted in slightly higher concentrations of butyrate. No differences were found between both age-groups. Taking together these results, it can be concluded that XOS produced from E. nitens by a biorefinery-based approach led to, at least, similar prebiotic activity as that observed with FOS.

Abstract
The controlled drug exposure test (DPT) is currently considered the gold standard for the diagnosis of drug allergy. Drug-induced adverse reactions (ADRs) are a growing reason for consultation in both primary and specialized care. Allergology consultations in Spain are the ones that usually study these ADRs and rule out immunological mechanisms involved in up to 90% of the cases consulted. An adequate approach to these cases has an obvious impact on the costs and efficacy of the treatments required by other specialists, so that if we did not use DPTs, patients would require more expensive, more toxic and less effective treatments in most of the cases. In recent years, a large number of new drugs have been developed and this document is intended to be a practical guide in the management of PDT with the vision of the Spanish Allergology Society. Diagnostic work begins with a detailed history of the patient. Skin tests are only useful for some medications, and in most cases the diagnosis can only be confirmed by DPT. Although there is usually cross-reactivity, DPTs can confirm the diagnosis and also help to find a tolerable alternative drug. The individual management of patients in a programmed way, taking into account both the type of drug to be studied and the patient´s comorbidities, usually allows a solution to be found for the majority of patients.

Abstract
High- and low-acetylated galactoglucomannooligosaccharides (GGMOS_Ac and GGMOS, respectively) were assayed as substrates in the TIM-2 in vitro colon model using, as inoculum, fecal microbiota from the elderly. The effects on the microbiota and their activity were also compared to a standard ileal efflux medium (SIEM). GGMOS resulted in higher organic acid productions and higher short-chain fatty acids/total organic acid molar ratios. Although comparable Actinobacteria abundances were observed with both substrates, GGMOS fermentation led to higher Firmicutes/Bacteroidetes ratios and lower Proteobacteria percentages than GGMOS_Ac. No differences were found concerning the percentages of beneficial genus such as Blautia, Faecalibacterium, Coprococcus, or Bifidobacterium. However, higher bacterial diversities and numbers of genera such as Oscillospira and Lachnospira were found with GGMOS_Ac. This suggests that GGMOS would be more suitable substrates for the elderly, even though GGMOS_Ac promoted positive effects that support the interest of further research using these oligosaccharides as "carriers" of desired substituents.

Abstract
Material removal technologies should be thoroughly analyzed not only to optimize operations but also to minimize the different waste emissions and obtain cleaner production centers. The study of environmental sustainability in manufacturing processes, which is rapidly gaining importance, requires activity modeling with material and resource inputs and outputs and, most importantly, the definition of a balanced scorecard with suitable indicators for different levels, including the operational level. This paper proposes a metrics deployment approach for the different stages of the product life cycle, including a conceptual framework of high-level indicators and the definition of machining process indicators from different perspectives. This set of metrics enables methodological measurement and analysis and integrates the results into aggregated indicators that can be considered for continuous improvement strategies. This approach was validated by five case studies of experimental testing of the sustainability indicators in material removal operations. The results helped to confirm or modify the approach and to adjust the parameter definitions to optimize the initial sustainability objectives.

Abstract
Herein, an efficient asymmetric aminoalkylation of pyrazolones with α-amido sulfones catalyzed by a quinine-derived squaramide in dichloromethane/aqueous media has been established. A variety of chiral amines were obtained with high yields (up to 98%) and excellent enantioselectivities (up to 99% ee). The corresponding products are transformed into optically active acetylated pyrazoles after treatment with Ac2O/Et3N, because of the instability of some adducts. The reaction tolerates a wide range of α-amido sulfones and different pyrazolones.

Abstract
Chiral cyclic ureas (2-imidazolinones) were prepared by the reaction of nitrones and isocyanoacetate esters using a multicatalytic system that combines a bifunctional Brønsted base-squaramide organocatalyst and Ag+ as a Lewis acid. The reaction could be achieved with a range of nitrones derived from aryl- and cycloalkylaldehydes with moderate diastereo- and good enantioselectivity. A plausible mechanism involving an initial formal [3 + 3] cycloaddition of the nitrone and isocyanoacetate ester, followed by rearrangement to an aminoisocyanate and cyclization to the imidazolinone, is proposed.

Abstract
Introduction: Almotriptan (ALT), a serotonin 5-HT1B/1D agonist has been used in the acute treatment of migraine with or without aura for 20 years, accumulating data on more than 15,000 patients in studies and from an estimated >150 million treated migraine attacks in daily clinical practice. The last major review of ALT was written almost 10 years ago. The current narrative review provides an overview of the experience gained with almotriptan over that time, and highlights data published in the last decade. Areas covered: Randomized clinical trials, observational studies, postmarketing studies and meta-analyses involving ALT for the treatment of acute migraine identified through a systematic literature search. Expert opinion: Triptans are a mainstay of anti-migraine treatment. Findings with ALT over the last 10 years have reinforced the positive efficacy and tolerability results that were reported during the first 10 years following its introduction. In particular, more recent clinical results have confirmed its efficacy in women with menstrual migraine, the usefulness of early intervention, long-term benefit in adults, and also its efficacy and safety in adolescents. Overall, ALT can be considered an optimal choice for managing acute migraine resistant to first-line drugs.

Abstract
Multiple sclerosis (MS) is an inflammatory and neurodegenerative autoimmune demyelinating disease of the central nervous system. Patients exhibit heterogeneous patterns of disabling symptoms, including spasticity. In the majority of patients with MS spasticity, it and its associated symptoms contribute to disability, interfere with performance of everyday activities, and impair quality of life. Even under treatment with oral antispasticity drugs, about a third of patients continue to experience spasticity of moderate to severe intensity, underscoring the need for additional treatment options. The efficacy of tetrahydrocannabinol:cannabidiol (THC:CBD) oromucosal spray as add-on therapy in patients with refractory MS spasticity has been demonstrated in clinical trials and observational studies. To gain insight into patients' response to treatment at the individual level, in-depth changes from baseline in various clinical scales and video-assessed parameters were evaluated in patients with resistant MS spasticity before and after 1 month of treatment with THC:CBD oromucosal spray. All 6 patients showed ≥20% improvement in the spasticity Numerical Rating Scale (i.e., were initial responders to treatment), but displayed individual variability in other spasticity-related parameters. Improved Modified Ashworth Scale scores were observed in 5 cases, with a reduction of -2/-3 points in lower limb scores for 1 patient who also showed benefit in terms of a more stable gait but modest improvement in the timed 10-meter walk test (10MWT). Improvement in the 10MWT (or 25-foot walk test) was noted in 4 of the 6 cases. THC:CBD oromucosal spray also improved upper limb function as indicated by faster 9-Hole Peg Test results.

Abstract
Background Persistent alopecia (PA) after docetaxel has been recently described. The aim of our study is to establish the incidence and characteristics of PA following adjuvant docetaxel for breast cancer (BC) and to test the ability of scalp cooling in prevention. Patients and methods BC patients receiving adjuvant chemotherapy followed or not by endocrine therapy (and a control group receiving only endocrine therapy) were interviewed in a single institution at 1.5 to 5 years following primary diagnosis searching for PA. A confirmatory prevalence study was later performed in other two institutions. Finally, a prevention study using prophylactic scalp cooling (PSC) with ELASTO-GEL hypothermia caps in patients receiving adjuvant docetaxel was performed. Results In the initial prevalence study (492 patients), minor forms of PA (grade 1) were recorded with all chemotherapy regimens and aromatase inhibitors. Patients receiving docetaxel regimens at cumulative dose (CD) ≥ 400 mmg/m2 presented a significantly higher prevalence of grades 1 PA (33–52%) and 2 PA (5–12%). Prevalence of grade 2 PA with docetaxel CD ≥ 400 mmg/m2 was confirmed in two other institutions. Overall, grade 2 PA was seen in 10.06% (95% CI 7.36–13.61) of 358 patients with docetaxel regimens reaching CD ≥ 400 mmg/m2, but not in patients with lower docetaxel CD, other chemotherapy regimens, or endocrine therapy alone. In prevention trial, no grade 2 PA occurred among 116 patients receiving adjuvant docetaxel (≥ 400 mmg/m2) and PSC followed-up after a 96 months median time. PSC was well tolerated. No scalp relapses were seen among 30 patients (22% of all inclusions) having disease relapse. Conclusion Adjuvant treatment with docetaxel (CD ≥ 400 mmg/m2) is associated with a significant rate of grade 2 PA, leading to wearing a wig, in around 10% of patients. This toxicity was completely prevented with scalp cooling. Clinical Trial Reference: NCT00515762.
