The host inflammatory response is critical in the progression of lung injuries in patients with SARS-CoV-2. Corticosteroids (CS) have been widely used as immunomodulating agents, but the right timing, dosage and type of molecule are unknown. In fact, the early use of CS could facilitate the viral replication but late administration may not prevent the alveolar damage. Nevertheless, a short administration of high doses of CS in the early stage of the inflammatory phase resulted in favorable outcomes. Noteworthy, some inhaled CS inhibited in vitro the viral replication of SARS-CoV-2. We aimed to define the place in therapy for CS in COVID-19 infection describing the features of patients who may benefit from their administration.Background Rising number of multidrug-resistant human pathogens demands novel antibiotics to this aim, unexplored natural sources are investigated to find new compounds. In this context, bacteria associated to medicinal plants, including Phragmites australis, might represent an important source of antimicrobial compounds. Materials & methods In the present work, 21 bacterial endophytes isolated from P. australis roots were tested, by cross-streaking, for their inhibitory activity against 36 multidrug-resistant pathogens isolated from food, clinical patients and hospitals. Results & conclusion Seven endophytes, belonging to Pseudomonas and Stenotrophomonas, were able to inhibit the growth of most of the target strains. In conclusion, this preliminary work could pave the way for the discovery of new antibiotics against superbugs.

Marfan syndrome (MFS) is an autosomal dominant disorder of the connective tissue caused by mutations in the

(fibrillin-1) gene encoding a large glycoprotein in the extracellular matrix called fibrillin-1. The major complication of this connective disorder is the risk to develop thoracic aortic aneurysm. To date, no effective pharmacologic therapies have been identified for the management of thoracic aortic disease and the only options capable of preventing aneurysm rupture are endovascular repair or open surgery. Here, we have studied the role of mitochondrial dysfunction in the progression of thoracic aortic aneurysm and mitochondrial boosting strategies as a potential treatment to managing aortic aneurysms.

Combining transcriptomics and metabolic analysis of aortas from an MFS mouse model (



) and MFS patients, we have identified mitochondrial dysfunction alongside with mtDNA depletion as a new hallmark of aortic aneurysm disease in MFS. To demonstrate the importance of mitochondrial decline in thes, and died prematurely. Restoring mitochondrial metabolism with the NAD precursor nicotinamide riboside rapidly reverses aortic aneurysm in



mice.

Mitochondrial function of VSMCs is controlled by the extracellular matrix and drives the development of aortic aneurysm in Marfan syndrome. Targeting vascular metabolism is a new available therapeutic strategy for managing aortic aneurysms associated with genetic disorders.

This study aims to evaluate, compare and rank the therapy techniques used in the management of autism spectrum disorder using multicriteria decision-making approaches. Materials & methods Fuzzy PROMETHEE and fuzzy TOPSIS approaches were used. Fuzzy PROMETHEE utilizes a pair-wise comparison of alternatives under the fuzzy environment while fuzzy TOPSIS utilizes geometric distance from the positive ideal solution under the fuzzy environment for the evaluation of the effectiveness of the alternatives.The techniques selected for evaluation are applied behavioral analysis, cognitive behavioral therapy, speech therapy and pharmacological therapy such as Risperidone and Aripiprazole. Criteria used in this study include efficacy, cost and side effects, and their weights are assigned based on specific patient conditions. Results The results indicate that applied behavioral analysis, cognitive behavioral therapy and speech therapy are the most preferred techniques, followed by Aripiprazole and Risperidone. Conclusion More criteria could be considered and the weights could be assigned according to the patient profile.Aim This study aimed to examine the effects of Clinical Pilates Exercises (CPE) on Health-Related Physical Fitness in Primary Caregivers. Patients & methods Fifty-five participants were randomly divided into the CPE group and the Control group. Individuals in the CPE group performed CPE two-times a week for 8 weeks. Results The intergroup comparisons showed that there were significant differences in favor of the CPE group in the sit-up test, body extension endurance, body flexion endurance, side bridge (right), squat test and flexibility tests (p less then 0.05). The intragroup comparisons revealed significant differences in the CPE group in the sit-up test, body flexion endurance, side bridge (both sides), squat test and flexibility tests (p less then 0.05). Conclusion CPEs are effective on improvement of health-related fitness parameters in the primary caregivers of children with disabilities. Clinical trial registration number NCT03729466.Aim To compare by micro-costing the costs incurred by quick diagnosis units of tertiary and second-level hospitals. Patients & methods We included 407 patients from a tertiary and secondary hospital unit. A bottom-up approach was applied. Results Cost per patient was €577.5 ± 219.6 in the tertiary versus €394.7 ± 92.58 in the secondary unit (p = 0.0559). Mean number of visits and ratio of successive/first visits were significantly higher in the former (3.098 and 2.07 vs 2.123 and 1.12, respectively). Personnel and indirect costs including their percent contribution to overall costs accounted for the main differences. Conclusion A greater volume of appointments, number of staff and staff time and a greater complexity of patients from the tertiary hospital unit justified the differences in cost outcomes.

The management of completely displaced fractures of the distal radius in children remains controversial. This study evaluates the outcomes of surgical and non-surgical management of 'off-ended' fractures in children with at least two years of potential growth remaining.

A total of 34 boys and 22 girls aged 0 to ten years with a closed, completely displaced metaphyseal distal radial fracture presented between 1 November 2015 and 1 January 2020. selleck chemicals After 2018, children aged ten or under were offered treatment in a straight plaster or manipulation under anaesthesia with Kirschner (K-)wire stabilization. Case notes and radiographs were reviewed to evaluate outcomes. In all, 16 underwent treatment in a straight cast and 40 had manipulation under anaesthesia, including 37 stabilized with K-wires.

Of the children treated in a straight cast, all were discharged with good range of mo (ROM). Five children were discharged at six to 12 weeks with no functional limitations at six-month follow-up. A total of 11 childrendial fractures in appropriately selected cases results in excellent outcomes without exposing the child to the risks of surgery. This study suggests that nonoperative management of these injuries is a viable and potentially underused strategy.

Most of Xanthomonads use the type III secretion system to inject transcription activator-like effector (TALE) proteins into host cell. TALEs bind to the effector binding elements in the promoter of host susceptibility genes triggering disease development. PacBio single-molecule real-time (SMRT) long-read sequencing technology was used to identify the TALE encoding genes, which is otherwise not possible using next-generation short-read sequencers. 1.74 Gb raw data containing 368980 subreads with an average read length of 4724 bp and longest read length of 77471 were generated. Subreads were assembled into 15 scaffolds generating ~5.4 Mb (348x) genome. Xcp exhibited close lineage with X. citri pv. citri with 98.78% average nucleotide identity. Of the 4263 protein-coding genes, eleven non-TALE type III effectors and two TALE encoding genes were identified.We investigate the differential ionization probability of chiral molecules in the strong-field regime as a function of the helicity of the incident light. To this end, we analyze the fourfold ionization of bromochlorofluoromethane (CHBrClF) with subsequent fragmentation into four charged fragments and different dissociation channels of the singly ionized methyloxirane. By resolving for the molecular orientation, we show that the photoion circular dichroism signal strength is increased by 2 orders of magnitude.Glasses, unlike their crystalline counterparts, exhibit low-frequency nonphononic excitations whose frequencies ω follow a universal D(ω)∼ω^4 density of states. The process of glass formation generates positional disorder intertwined with mechanical frustration, posing fundamental challenges in understanding the origins of glassy nonphononic excitations. Here we suggest that minimal complexes-mechanically frustrated and positionally disordered local structures-embody the minimal physical ingredients needed to generate glasslike excitations. We investigate the individual effects of mechanical frustration and positional disorder on the vibrational spectrum of isolated minimal complexes, and demonstrate that ensembles of marginally stable minimal complexes yield D(ω)∼ω^4. Furthermore, glasslike excitations emerge by embedding a single minimal complex within a perfect lattice. Consequently, minimal complexes offer a conceptual framework to understand glasslike excitations from first principles, as well as a practical computational method for introducing them into solids.Precise knowledge of the charge and rigidity dependence of the secondary cosmic ray fluxes and the secondary-to-primary flux ratios is essential in the understanding of cosmic ray propagation. We report the properties of heavy secondary cosmic ray fluorine F in the rigidity R range 2.15 GV to 2.9 TV based on 0.29 million events collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The fluorine spectrum deviates from a single power law above 200 GV. The heavier secondary-to-primary F/Si flux ratio rigidity dependence is distinctly different from the lighter B/O (or B/C) rigidity dependence. In particular, above 10 GV, the F/Si/B/O ratio can be described by a power law R^δ with δ=0.052±0.007. This shows that the propagation properties of heavy cosmic rays, from F to Si, are different from those of light cosmic rays, from He to O, and that the secondary cosmic rays have two classes.Under uniaxial shock compression, the steepness of the plastic shock front usually exhibits power law characteristics with the Hugoniot pressure, also known as the "Swegle-Grady law." In this Letter, we show that the Swegle-Grady law can be described better by a third power law rather than the classical fourth power law at the strain rate between 10^5-10^7  s^-1. A simple dislocation-based continuum model is developed, which reproduced the third power law and revealed very good agreement with recent experiments of multiple types of metals quantitatively. New insights into this unusual macroscopic phenomenon are presented through quantifying the connection between the macroscopic mechanical response and the collective dynamics of dislocation assembles. It is found that the Swegle-Grady law results from the particular stress dependence of the plasticity behaviors, and that the difference between the third power scaling and the classical fourth power scaling results from different shock dissipative actions.
