Nature and Pandemic
Authors: Espinoza Lolas Ricardo 
Published: March 2022

The article shows how the Covid-19 pandemic is not only a matter associated with nature, but it is an essential topic in order to understand humanity today, because at the beginning of the pandemic it was immediately shown that nature was behind this disaster, because it was, in a certain way, taking revenge on the humans. After all, the very conception of nature that we use today is a human conception, created from the subjectivity of the Self, that goes hand in hand with the modern creation of the nation-state. Nature, nation-state, etc., are creations of the Self and in this way nature is understood as something objective, but at the same time the human subject treats himself as an object. Here lies the very problem, because neither the Self nor the nature behave in an objective way, but both moments are made visible from a dynamic articulation of the movement of one in the other. This vision was part of the conception of the ancient Greeks and by Nietzsche and other current thinkers such as Žižek.
The Sexistential Vulnerability of Bodies in Contact in the Philosophy of Jean-Luc Nancy
Authors: Recchia Luciani Francesca Romana 
Published: March 2022

The philosophy of sexual existence as a mode of expression of the “con-being”, pivotal in his book “Sexistence”, occupies a relevant space in Jean-Luc Nancy’s late philosophical production. In this text, the body, the touch, the sex are protrusions that dot a conceptual map that is the result of a long philosophical militancy marked by an authentic “haptic ontology”, a sign of a thought of relationality, interdependence and “sexistencial vulnerability” that connotes the bodies in contact that we all are. But Nancy goes so far as to elaborate a “trans-ontology” through which the “r-existence (resistance) of sexistence” is manifested, that is to say that stubborn rejection of distinct and different bodies to the homologation and uniformity of the identical and of the identity shared by “trans-feminism” which makes its strong point of the inexhaustible combinatorics of the sexes. Thus, both for the sexistencial approach and for the transfeminist one, at the heart of every theory are the lives and practices of distinct and different sexual bodies in relation.
Universal Design for Learning and Inclusive Teaching: Future Perspectives
Authors: Rossi Martina 
Published: March 2022

This contribution aims to reflect on the didactic and methodological changes brought about by Distance Learning, with particular regard to the concept of Inclusive Teaching. During the last year, in fact, the epidemiological emergency dictated by Covid-19 has led to the emergence of new needs, imposing a redesign of tools and resources in use. All this has had a strong impact on students with disabilities and Specific Learning Disorders (SLD), who, in addition to having fewer digital skills than their European peers, were suddenly forced to follow lessons at home without the physical support of the teacher. It was necessary, in fact, to think and re-think about the design of inclusive educational interventions. From a methodological and conceptual point of view, Inclusive Teaching is linked to the concept of Universal Design for Learning (UDL), an inclusive psycho-pedagogical approach that aims to break down the barriers that exist in learning processes. During the pandemic period, one of the major challenges that scholars have begun to consider is applying the UDL approach, generally used in in-person classes, lectures and online courses.
The Vagaries of the Superego
Authors: Žižek Slavoj 
Published: March 2022

Starting from the distinction between “ideal ego”, “ego-ideal” and “superego” structured from the Imaginary-Symbolic-Real triad made by Lacan, this study investigates how is possible to distinguish the a-sexual social space from the domain of libidinally-cathexed interactions. Through the analysis of Balibar’s, Miller’s, Schuster’s and Hägglund’s ideas, paths and strategies are defined to analyze the existing dynamics between symbolic power, law and superego. What emerges is the reconstruction of a new subjectivity which is capable, at the same time, to overcome the jouissance-superego dynamic at the basis of Lacanian reflection and face the challenges of contemporary post-humanism. Therefore, what subject stands for is the inhuman core of being-human, what Hegel called selfrelating negativity, what Freud called death drive. The text proposes, in short, how the Subject is what is in a human being more than human, the immortality of the deathdrive which makes it a living dead, something that insists beyond the cycle of life and death.

Authors: Potbhare Renuka , RaviKumar Ameeta , Munukka Eveliina , Lahti Leo , Ashma Richa 
Published: March 2022

Background
Human skin harbors complex transient and resident microbial communities that show intra- & inter-individual variation due to various environmental and host-associated factors such as skin site, diet, age, gender, genetics, or the type and use of cosmetics. This variation remains largely uncharacterized in the Indian population; hence, the present study aims to characterize the variation in skin microbiota among individuals of Indian origin and quantify associations with age, diet, and geography.

Methods
Axillary sweat samples from genetically unrelated individuals (N = 58) residing in the three geographical locations of Maharashtra, India, were collected using a sterile cotton swab. Bacterial DNA was extracted using a standard protocol and checked for quality. Variable regions (V3–V4) of the 16S rRNA gene were sequenced using the Illumina platform. We used standard methods from microbiota bioinformatics, including alpha and beta diversity, community typing, and differential abundance, to quantify the association of skin microbiota with age, diet, and geographical location.

Results
Our study indicated the prevalence of phyla- Firmicutes, Proteobacteria, and Actinobacteria, consistent with previous reports on skin microbiota composition of the world population level. The alpha diversity (Shannon index) was significantly associated with the age group (Kruskal–Wallis test, p = 0.02), but not with geography (p = 0.62) or diet (p = 0.74). The overall skin microbiota community composition was significantly associated with geographical location based on Community State Types (CST) analysis and PERMANOVA (R2 = 0.07, p = 0.01). Differential abundance analysis at the genus level indicated a distinctively high abundance of Staphylococcus and Corynebacterium among individuals of the Pune district. Pseudomonas and Anaerococcus were abundant in individuals from Ahmednagar whereas, Paenibacillus, Geobacillus, Virgibacillus, Jeotgalicoccus, Pullulanibacillus, Delsulfosporomusa, Citinovibrio, and Calditerricola were abundant in individuals from Nashik district.

Conclusion
Our work provides one of the first characterizations of skin microbiota variation in different sub-populations in India. The analysis quantifies the level of individuality, as contrasted to the other factors of age, geography, and diet, thus helping to evaluate the applicability of skin microbiota profiles as a potential biomarker to stratify individuals.

Published: March 2022

ABSTRACT

Objective
The purpose of this study was to investigate if COVID-19 lockdown affected stress-perception and burnout in chiropractic students from our institution.

Methods
Stress and burnout in students were assessed using the Perceived Stress Scale and the Maslach Burnout Inventory. The surveys were sent out electronically in March 2020 to chiropractic students enrolled at our college. Data were analyzed with descriptive statistics and t test or analysis of variance to determine statistically significant differences between variables. Data were compared with that obtained in 2018, under no lockdown conditions.

Results
The survey had an overall response rate of 48.94%. Women presented statistically significant higher values for stress (p = .002) and exhaustion (p = .007). Younger students tended to suffer more stress than their older peers. When comparing lockdown data with that of 2018, students presented significantly lower stress levels but higher cynicism.

Conclusion
Women presented higher values for stress and exhaustion than the men. When comparing data with a prior study in 2018 with no lockdown situation, current students appeared to have lower levels of stress but increased cynicism.

ObjectiveTo compare all‐cause and cause‐specific mortality risk between patients with gout and patients without gout in the Veteran's Health Administration (VHA).MethodsWe performed a matched cohort study, identifying patients with gout in the VHA from January 1999 to September 2015 based on the presence of ≥2 International Classification of Diseases, Ninth Revision codes for gout (274.X). Gout patients were matched up to 1:10 on birth year, sex, and year of VHA enrollment with patients without gout and followed until death or end of study (December 2017). Cause of death was obtained from the National Death Index. Associations of gout with all‐cause and cause‐specific mortality were examined using multivariable Cox regression.ResultsGout (n = 559,243) and matched non‐gout controls (n = 5,428,760) had a mean age of 67 years and were 99% male. There were 246,291 deaths over 4,250,371 patient‐years in gout patients and 2,000,000 deaths over 40,441,353 patient‐years of follow‐up in controls. After matching, gout patients had an increased risk of death (hazard ratio [HR] 1.09 [95% confidence interval (95% CI) 1.08–1.09]), which was no longer present after adjusting for comorbidities (HR 0.98 [95% CI 0.97–0.98]). The strongest association of gout with cause‐specific mortality was observed with genitourinary conditions (HR 1.50 [95% CI 1.47–1.54]). Gout patients were at lower risk of death related to neurologic (e.g., Alzheimer's disease and Parkinson's disease) (HR 0.63 [95% CI 0.62–0.65]) and mental health (HR 0.66 [95% CI 0.65–0.68]) conditions.ConclusionA higher risk of death among gout patients in the VHA was related to comorbidity burden. While deaths attributable to neurologic and mental health conditions were less frequent among gout patients, genitourinary conditions were the most overrepresented causes of death.

Published: March 2022

ObjectivesTo assess test–retest reliability of musculoskeletal ultrasound (US) measures of inflammation in patients with knee osteoarthritis (OA) and to assess the sensitivity to change of US measures of inflammation in patients with knee OA.MethodsTo mimic a common clinical scenario, 36 patients (n = 70 knees) with symptomatic knee OA who were in stable condition underwent 2 assessments within 14 days by different operators and different US machines, graded by a single rater. Test–retest reliability was measured using Cohen's kappa coefficient, intraclass correlation coefficient (ICC), and absolute agreement parameters. A total of 51 patients (n = 72 knees) were tested immediately before and 21–28 days after intraarticular glucocorticoid injection to investigate sensitivity to change and longitudinal construct validity. Paired t‐tests and standardized response mean (SRM) were used to assess sensitivity to change. Multivariate linear regression was used to investigate longitudinal construct validity of US with Knee Injury and Osteoarthritis Outcome Score (KOOS) pain scores, while adjusting for covariates.ResultsUS measures of inflammation demonstrated moderate (κ = 0.41, 0.60) to substantial (κ = 0.61, 0.80) agreement. Quantitative measures of synovitis and effusion demonstrated good test–retest reliability (ICC2,1 0.71, 0.92). US measures of synovitis and effusion demonstrated low‐to‐moderate sensitivity to change (SRM –0.29, –0.50). The associations between changes in US measures and KOOS pain scores over time were low, and 95% confidence intervals included zero.ConclusionIn a clinical setting, US measures of inflammatory features of knee OA have substantial reliability and low‐to‐moderate sensitivity to change, whereas measures of structural OA features are less reliable. Longitudinal construct validity of US measures of synovitis and effusion to KOOS pain scores is not strongly supported.

Published: March 2022

ObjectivesPatients with systemic lupus erythematosus (SLE) have a high risk of cardiovascular disease that could potentially increase postoperative major adverse cardiac events (MACE). We determined the rate of MACE in patients with SLE undergoing noncardiac surgery using national claims‐based data.MethodsThis was a retrospective cohort study using Optum Clinformatics Data Mart from 2007 to 2020. We identified a cohort of patients with SLE who had undergone noncardiac surgeries using Current Procedural Terminology codes. We also identified two control cohorts without SLE, one with diabetes mellitus (DM) and one without DM. After matching cases and controls by age and sex, the odds of MACE were estimated using multivariable logistic regression models also including race and the Revised Cardiac Risk Index (RCRI) scores. We also examined use of preoperative cardiac testing.ResultsWe identified 4750 patients with SLE, 496,381 DM controls, and 1,484,986 non‐DM controls. After matching, the odds ratio (OR) for MACE in patients with SLE versus non‐DM controls was 1.51 (95% confidence interval 1.09‐2.08), which decreased after adjustment for RCRI score (OR: 0.97, 95% confidence interval 0.7‐1.36). No significant differences were observed in the incidence of MACE between patients with SLE and DM controls (0.82 vs 1.04, P = 0.16). High‐risk patients with SLE (RCRI score of ≥3) were less likely to receive preoperative cardiac testing than non‐DM controls (42.7% vs 35.1%, P < 0.05).ConclusionPatients with SLE have an increased risk of postoperative MACE, which is driven by increased RCRI scores. Concerningly, high‐risk patients received less cardiac testing 2 months before surgery than non‐DM controls.

AbstractAlthough much research on device engineering have brought about significant improvements in PM6:Y6‐based polymer solar cell (PSCs) performance, there is still a lack of relevant research to solve the problems caused by the over‐aggregation of Y6 and the long‐term stability of the device morphology. Herein, a newly designed and synthesized low‐bandgap asymmetric small molecule acceptor TIT‐2Cl based on thieno[3,2‐b]indole core is elaborately introduced into PM6:Y6‐based PSCs to suppress the over‐aggregation of Y6 molecules with significantly increased efficiency from 15.78% to 17.00%. Moreover, the addition of TIT‐2Cl contributes to improved light harvesting, the lowest unoccupied molecular orbital level of Y6:TIT‐2Cl, charge separation, transport, and extraction. Simultaneously, the PSCs are further prepared by using the progressive spin‐coating method of layer‐by‐layer (LBL). Due to the formation of vertical phase distribution and the improvement of carrier transport performance, the champion efficiency of LBL‐type ternary PSCs reaches 18.18%, which is the highest efficiency reported for PM6:Y6‐based PSCs, along with superior stability and compositional insensitivity. Therefore, the results show that the combination of ternary strategy by incorporating appropriate asymmetric molecules and the LBL method is an effective means to fabricate highly efficient stable PSCs.

Published: March 2022

AbstractSeawater electrolysis is an attractive technique for massive green hydrogen production owing to the dominant advantages of seawater resources, namely low‐cost and limitlessness. However, the oxygen evolution reaction (OER) catalysts will be easily deactivated for severe seawater Cl− permeation and corrosion. Herein, a structural buffer engineering strategy is reported to endow the Co2(OH)3Cl with long‐term operation stability and a high OER selectivity of ≈99.6% in seawater splitting. The lattice Cl− of Co2(OH)3Cl can act as the structural buffer, whose continuous leaching during OER can leave vacancies for seawater Cl− invasion, so as to avoid catalyst deactivation. Accordingly, Co2(OH)3Cl can maintain 99.9% of its initial current density after 60 000 s operation, while that of Co(OH)2 decays by 52.7% in 7 000 s. Meanwhile, the lattice Cl− of Co2(OH)3Cl can optimize the binding energy of reaction intermediates on the neighboring OCoO site. Thus, Co2(OH)3Cl exhibits a current density of 330.5 mA cm–2 at the potential of 1.63 V versus RHE, 45.9 times higher than that of Co(OH)2. The structural buffer strategy may be applied to incorporate other metal oxides with suitable anions, and effectively boost their OER activity and stability in alkaline seawater.

AbstractThe laser‐induced graphene (LIG) has a great potential in electrochemically active electrodes for wearable biosensors. Herein, for the first time, a stretchable and non‐enzymatic glucose sensor based on LIG derived from commercial poly(ether sulfone) (PES) membranes is reported. The LIG is in situ transferred onto an elastomer and tightly wrapped by the elastomer in one laser carbonization step. Superior to the conventional casting and demolding transfer process, this method avoids the LIG's morphology distortion and loss. By adjusting the laser settings and the patterns, hierarchically structured electrodes are prepared with greatly increased surface areas for glucose detection. The electrodeposited dendritic gold‐nanoparticles act as the catalyst for glucose sensing. The optimized flexible sensor demonstrates a linear range for glucose from 10 μm to 10.0 mm and a detection limit of 26 μm. The sensor shows a sensitivity of 0.024 ± 0.001 mA mm−1 and selectivity toward other interfering metabolites, as well as excellent performance under mechanical bending (stable performance after 500 bending cycles) and stretchability (resistance unchanged after 1000 cyclic stretching at 20% strain). Due to the simplicity of preparation and extraordinary fidelity, the novel PES‐LIG sensor is a promising candidate for the next generation of skin‐adherent diagnostic devices and wearable electronics.

AbstractIn the context of diminishing atmospheric CO2 emissions, there is an urgent need to develop processes that can be carried out at a scale commensurate with appropriate CO2 volumes. One possible reaction is the transformation of CO2 to methane (Sabatier reaction). Due to its chemical stability, catalytic CO2 hydrogenation to methane is carried out at temperatures of 450 °C or higher and pressures above 5 bars, thus, requiring a significant energy input. One alternative possibility to conventional thermal catalysis is the use of solar light as the primary energy, performing the photocatalytic CO2 hydrogenation. In this broad context, the present study shows the photocatalytic activity of nanometric films of oriented Ru nanoparticles (NPs) strongly grafted on defective graphene. These graphene films (thinner than 20 nm) containing Ru NPs nanoplatelets (less than 2 nanomolRu/cm2) are among the most active photocatalysts ever prepared for CO2 hydrogenation and operate through photoinduced charge separation.

AbstractMetal sulfide solid‐solutions have served as one of the most promising photocatalysts due to continuously adjustable bandgap structure and light‐absorption performance. Herein, a novel quaternary CdIn2S4‐xSex solid‐solution nanocrystal photocatalyst is prepared by one‐step hydrothermal synthesis, including the initial production of CdIn2S4‐x(SeO3)x and its in situ reduction of SeO32− to produce Se2− by N2H4. It is found that the bandgap structure of CdIn2S4‐xSex nanocrystals can be adjusted from 2.42 to 1.87 eV by varying the molar ratio of Se/S. Compared with pure CdIn2S4, the CdIn2S4‐xSex solid‐solution photocatalyst clearly represents excellent photocatalytic hydrogen production performance, while the CdIn2S4‐xSex (x = 0.4) solid‐solution nanocrystal exhibits the optimal hydrogen‐production efficiency of 314.24 µmol h−1, which is 3.3 times superior to that of CdIn2S4 (94.83 µmol h−1). It is found that the introduction of Se increases the charge density of S2− to form electron‐enriched S(2+δ )−, which can promote the effective adsorption of H+ for the following interfacial hydrogen‐evolution reaction. Meanwhile, the CdIn2S4‐xSex solid‐solution nanocrystals have a higher conduction band and stronger visible‐light absorption ability, which is also essential for accelerating photocatalytic hydrogen‐production efficiency. This study may offer possibilities for developing high‐performance photocatalysts.
