Recent mortality rates due to complications of medical and surgical care in the US
Authors: Mattiuzzi Camilla , Plebani Mario , Lippi Giuseppe 
Published: May 2024

Abstract

Objectives
Medical errors and complications pose a major threat to the safety of healthcare systems worldwide. This article was hence aimed at determining the current burden of complications of medical and surgical care in the US.

Methods
We searched the latest version of the US Centers for Disease Control and Prevention (CDC) WONDER online database (years 2018–2022) using ICD-10 codes Y40-Y84 (complications of medical and surgical care).

Results
The age-adjusted death rate for complications of medical and surgical care increased from 1.17 × 100,000 in 2018 to 1.49 × 100,000 in 2021, but then declined to 0.85 × 100,000 in 2022. The gender-specific analysis showed a similar trend, with the age-adjusted death rate values always being higher in men than in women. A clear age-dependent relationship was also found in the crude mortality rate for complications of medical and surgical care, as higher death rates were observed in older patients.

Conclusions
This analysis reveals that the burden of complications of medical and surgical care has increased over time, especially during the COVID-19 pandemic, but has then considerably declined in 2022. However, root cause analysis and actions are still needed for preventing the still noticeable consequences of medical complications.
Bees (Hymenoptera: Apoidea) diversity and synanthropy in a protected natural area and its influence zone in western Mexico

Published: May 2024

Abstract
Mexico’s wild bee richness includes 1,800 species, however, there is a lack of studies on this group in the country. Therefore, it is of extreme importance to intensify the study on this group of insects, so this research aimed to compile an inventory of the melittofauna of Sierra de Quila, Jalisco, Mexico, to evaluate alpha diversity in different types of vegetation, and assess which of the most abundant bee species are synanthropic (organisms that live near and benefit from humans and their environmental modifications). Bees were collected and recorded over two years between 10:00 and 16:00 h, in the flora and fauna protection area of Sierra de Quila and its region of influence, using entomological nets. A total of 15,641 individuals of 233 species belonging to 66 genera and five families were recorded, of which Apidae is the best represented family with 88 species, followed by Halictidae with 54 species, Megachilidae with 49 species, Andrenidae with 24 species, and Colletidae with 18 species. Tropical dry forest showed a higher richness of wild bees than the pine-oak forest, eight species were asynanthropic and only five species were eusynanthropic. Our results show that Sierra de Quila is one of the richest areas in bee species for the state of Jalisco, making it an important area for the conservation of this group of native pollinators.
An experimental validation of diffusion-based devolatilization models in extruders using post-industrial and post-consumer plastic waste

Published: May 2024

Abstract
Extrusion is a key process in mechanical recycling. In a degassing step, volatile components, including all impurities and moisture, are removed from a polymer melt to ensure consistently high quality of the recyclates. Predicting devolatilization performance is therefore of interest in the design of degassing screws; in the plastics industry, it also plays an important role in the transition from a linear to a circular economy. Using two different devolatilization models, we first modelled the degassing process of a lab-scale twin-screw extruder and an industrial-scale recycling single-screw extruder. We then predicted the devolatilization performance of both machines, validated the results with experimental data obtained from emissions tests carried out with post-industrial and post-consumer polypropylene materials and performed linear regression analysis to compare our two models in terms of predictive quality. Our results showed that both models are equally suitable for reliable prediction of the devolatilization performance.
Guiding light with surface exciton–polaritons in atomically thin superlattices

Published: May 2024

Abstract
Two-dimensional materials give access to the ultimate physical limits of photonics with appealing properties for ultracompact optical components such as waveguides and modulators. Specifically, in monolayer semiconductors, a strong excitonic resonance leads to a sharp oscillation in permittivity from positive to even negative values. This extreme optical response enables surface exciton–polaritons to guide visible light bound to an atomically thin layer. However, such ultrathin waveguides support a transverse electric (TE) mode with low confinement and a transverse magnetic (TM) mode with short propagation. Here, we propose that realistic semiconductor–insulator–semiconductor superlattices comprising monolayer WS2 and hexagonal boron nitride (hBN) can improve the properties of both TE and TM modes. Compared to a single monolayer, a heterostructure with a 1-nm hBN spacer separating two monolayers enhances the confinement of the TE mode from 1.2 to around 0.5 μm, while the out-of-plane extension of the TM mode increases from 25 to 50 nm. We propose two simple additivity rules for mode confinement valid in the ultrathin film approximation for heterostructures with increasing spacer thickness. Stacking additional WS2 monolayers into superlattices further enhances the waveguiding properties. Our results underscore the potential of monolayer-based superlattices as a platform for visible-range nanophotonics with promising optical, electrical, and magnetic tunability.
Happiness and the Biopolitics of Knowledge: From the Contemplative Lifestyle to the Economy of Well-Being and Back Again
Authors: Cimino Antonio 
Published: May 2024

Abstract
The article explores the relationship between two different approaches to happiness and knowledge, that is, the contemplative model and the economistic and instrumental model. Whereas the former equates happiness with the contemplative life, the latter separates happiness from knowledge and subordinates both to what present-day policy-makers call “the economy of well-being.” While biopolitical modernity seems to have rendered the contemplative model obsolete and purposeless, the article suggests reviving the contemplative lifestyle, by putting forward three arguments. First, it contends that we should challenge the economistic and instrumental model, by reaffirming the principle that knowledge and happiness are primarily intrinsic values and ends in themselves. Second, the two models do not necessarily exclude each other and we should strive to combine them. Third, the envisaged integration of the two models requires that we revise them significantly. The elitist and metaphysical character of the traditional contemplative model must be abandoned as it is no longer palatable to modernity. Also, the primacy of economic and instrumental rationality that defines the modern biopolitics of knowledge must be questioned.

AbstractChinese onion (Allium chinense G. Don) is an edible vegetable as well as a traditional Chinese medicine. It is rich in steroidal saponins and possesses broad health benefits. In this study, the optimal extraction protocol of the total saponins from Chinese onion (ACS) was explored, and the content of the total steroidal saponins in ACS reached 56.62%. Network pharmacology was applied to predict the related signalling pathways and targets between the main phytochemicals in ACS and hypercholesterolaemia. Enrichment analysis showed that ACS might intervene hypercholesterolaemia through the PI3K-Akt signalling pathway. Meanwhile, cholesterol-lowering effects were verified by ACS intervention in high-cholesterol diet-induced hypercholesterolaemia in Kunming mice. Compared with the model group, the TC and LDL-C levels of mice were decreased and the HDL-C level increased significantly after administration of ACS at a dose of 200 mg kg−1 day−1. The body weight gain, liver index, and atherosclerosis index all decreased dramatically. ACS could significantly reduce the fat content in the liver and reduce the number of fat droplets from the haematoxylin and eosin (H&E) staining of mouse liver. The immunohistochemical staining indicated that ACS could up-regulate the expression of PI3K protein in the liver, thus playing an anti-hypercholesterolaemic role. This study indicated that ACS exhibited significant therapeutic and preventive effects on hypercholesterolaemia, and exerted anti-hypercholesterolaemia through the PI3K-Akt signalling pathway.

Published: May 2024

AbstractThis paper introduces an in-line dye tracer experiment to measure the residence time functions in continuous concrete processing. These functions quantify the material-system interdependency and can be used to compare different material-system combinations and for quality and process control. A Rhodamine B solution was used as the tracer material and detected by measuring the color intensity using a digital image processing technique. The experiment was validated on a 3D concrete printing system by comparing the results of impulse, step-up and step-down inputs with different tracer quantities. The results show that a high signal-to-noise ratio can be obtained with low tracer concentrations. For the examined combination of material and system, an impact on the original process was only observed for the step-up inputs at high tracer quantities. It is concluded that the presented method is cost-effective and non-labor-intensive and, therefore, has the potential for wide adoption and integration in automated workflows.

Published: May 2024

This article deals with the singularly perturbed nonlinear Volterra-Fredholm integro-differential equations. Firstly, some priori bounds are presented. Then, the finite difference scheme is constructed on non-uniform mesh by using interpolating quadrature rules [5] and composite numerical integration formulas. The error estimates are derived in the discrete maximum norm. Finally, theoretical results are performed on two examples and they are compared for both Bakhvalov (B-type) and Shishkin (S-type) meshes.

Tamsulosin is a first-line drug in the treatment of lower urinary tract symptoms (LUTS) in benign prostatic hyperplasia (BPH). Despite high estimates of its efficacy and safety, it rates may vary due to genetic polymorphisms of genes for the enzymes involved in the drugs metabolism.The aim of the work was to evaluate the carriage influence of genes polymorphisms of the CYP3A enzymes group of tamsulosin metabolizers on the efficacy and safety of therapy in patients with LUTS in BPH.Materials and methods. A total of 142 patients with LUTS, with an established BPH diagnosis (N40 according to ICD-10) were included in the study and underwent all stages. All patients received monotherapy with tamsulosin 0.4 mg/day for at least 8 weeks. An IPSS questionnaire with the definition of quality of life, a prostate ultrasound with the determination of the prostate volume and residual urine, as well as uroflowmetry, were used to evaluate the results of the treatment. Controls were performed at 2, 4 and 8 weeks from the start of the therapy. The carriage of polymorphic markers CYP3A4 (*1B, *22) and CYP3A5*3 was determined in patients; HPLC was used to determine drug concentrations in blood plasma and levels of cortisol and its metabolite 6-beta-hydroxycortisol in urine to assess the phenotypic activity of CYP3A.Results. No statistically significant associations between CYP3A phenotype (defined by CYP3A4 and CYP3A5 genotypes) and clinical parameters of the tamsulosin therapy efficacy and the safety assessment in the studied sample of patients were found (p >0.05). Similar data were obtained for individual variants of CYP3A4*1B, CYP3A4*22, CYP3A5*3 (p >0.05). The comparison of the tamsulosin residual equilibrium concentration values in patients in the study sample with respect to the carriers of CYP3A4 and CYP3A5 gene variants did not reveal the presence of significant differences in either CYP3A phenotypes and carriers and non-carriers of individual CYP3A4*1B (p=0.57), CYP3A4*22 (p=0.37) and CYP3A5*3 (p=0.76) variants. No association was found between the metabolic ratio of 6-beta-hydroxycortisol / cortisol in urine and the CYP3A phenotype encoded by a combination of genotypes of CYP3A4 and CYP3A5 gene variants (p >0.05).Conclusion. A possible association between the carriage of CYP3A4*1B, CYP3A4*22, CYP3A5*3 variants, a CYP3A activity assessed by the content of an endogenous substrate of this isoenzyme and its metabolite in urine, the level of plasma concentration of the drug, and the efficacy and safety of tamsulosin, has not been confirmed. The contribution of CYP3A4 and CYP3A5 genetic polymorphisms to clinical parameters of the tamsulosin therapy requires a further study.

The aim of the work was to compare the effects of ademethionine, acetylcysteine and taurine on the zoosocial behavior of rats in a post-intoxicated state after an acute ethanol poisoning.Materials and methods. The study was conducted on male rats of the Wistar line. The post-intoxication state was modeled by a single injection of ethanol (3 g/kg, intraperitoneally). 30 min after awakening, the animals were injected with a physiological solution, acetylcysteine (1 g/kg), ademetionine (100 mg/kg) or taurine (40 mg/kg). A zoosocial interaction test was performed 30 min after the administration.Results. Among the behavioral indicators investigated, the following were validated: the number of acts of freezing, their duration, the number of acts of sniffing in front, the number of acts of avoidance and the number of vertical stances without support (p <0.05 between the values of the negative and positive control groups in all cases). The administration of acetylcysteine, ademetionine and taurine reduced the number of freezing acts by 53.64, 7.27 and 24.51%, respectively (p <0.05 when compared with the indicator index in the animals from the positive control group in all cases). The administration of acetylcysteine and taurine reduced the number of avoidance acts by 50 and 10%, respectively (p <0.05 when compared to that of the animals from the positive control group in both cases). All amino acids normalized the communicative performance, although it did not differ from that of the animals from the positive control group (p >0.05). Alcoholization reduced the number of vertical stances by 65% (p <0.001 when compared with that in the animals from the negative control group), and when followed by the administration of ademetionine and taurine, the reduction was 38 and 36%, respectively (p <0.05 when compared to that in the animals from the negative control group).Conclusion. According to the data obtained, sulfur-containing amino acids, primarily those that had central effects, normalized neuronal functions, positively influencing a complex behavior of rats. Taking into account the results of the previous studies, it was possible to conclude that the therapeutic effect of ademetionine and taurine in the context of a post-intoxication state is mediated by their central effects, which are not so pronounced in comparison with acetylcysteine.

Published: May 2024

Nonlinear loads, a crucial component of power systems grids, pose a challenge due to harmonics injection. Our research tackles this issue with a novel approach - a modified green plug / switched filter compensation scheme using fuzzy logic controllers. This innovative scheme, presented in the paper, utilizes dual action pulse width modulation to ensure switching functions from harmonic reduction and capacitive compensation for inrush nonlinear type AC loads. The scheme&#039;s multi-loop regulations and online switching effectively handle dynamic type slow acting inrush, motorized and other rectifier type-nonlinear loads, enhancing power factor, power quality at source and load buses, and reducing total harmonic distortion at key source and sensitive nonlinear load buses. A simulation model in the MATLAB/SIMULINK software environment demonstrates the efficiency of the proposed FACTS technique. The results show that voltage, current, active power, reactive power, power factor regulation, and effective energy utilization are achievable with the designed FACTS-MFCC-SFC. The switched modulated AC green plug filter significantly improves power quality and enhances power factor in the case of inrush and nonlinear loads.
