Anxiety in L2 Chinese from different angles
Authors: Zhou Jing
Published: September 2023

The current study examines the influence of experience, reading and writing anxieties, and self-assessed proficiency on foreign language anxiety in the context of learning Chinese as a foreign language. Data were collected using questionnaires from 93 learners of Chinese and analyzed using correlational and multiple regression methods. Results indicated that learners at level 200 (i.e., intermediate low/mid) were more anxious compared to those at level 400 (i.e., advanced low/mid). Foreign language anxiety, foreign language reading anxiety, and foreign language writing anxiety were significantly correlated with each other. Foreign language reading anxiety, foreign language writing anxiety, and self-assessed proficiency (listening and reading) were shown to significantly predict foreign language anxiety in the context of L2 Chinese.

This work evaluates the in vitro antioxidant and antidiabetic activities of two metformin hydrochloride-based Schiff bases. Moreover, the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was used to examine the in vitro cytotoxic effects of HL1 and HL2 on the A549 lung cancer cell line. The two Schiff bases that have been previously synthesized by using two effective, green techniques, namely stirring and microwave-assisted, are N,N-dimethyl-N′-[(Z)-(2-nitrophenyl) methylidene] imidodicarbonimidic diamide and N,N-dimethyl-N′-[(Z)-(4-nitrophenyl) methylidene] imidodicarbonimidic diamide, indicated by HL1 and HL2, respectively. Studies of antidiabetic efficacy using alpha-amylase revealed that HL2 has a higher inhibition than HL1, but the results on sucrase enzyme showed that HL1 had the highest inhibitory action, whereas the outcome of the antioxidant test with the 2,2-diphenyl-1-picrylhydrazyl assay demonstrated that HL2 was the most effective antioxidant, followed by ascorbic acid and HL1. In the MTT assay, HL1 had the best result, with an IC50 value of 57.13 µg/mL compared to HL2 with an IC50 value of 76.83 µg/mL. It was observed that HL1 was the most effective against the human lung cancer cell line A459. The findings were supported by computational and pharmacokinetic studies (SwissADME). Based on empirical and computational studies, we suggest that HL1 and HL2 are promising candidates as antioxidants and antidiabetics after being examined in vivo.
A new approach to model the fluid dynamics in sandwich packings
Authors: Franke Patrick , Shabanilemraski Iman , Schubert Markus , Hampel Uwe , Kenig Eugeny Y.
Published: September 2023

Sandwich packings represent new separation column internals, with a potential to intensify mass transfer. They comprise two conventional structured packings with different specific geometrical surface areas. In this work, the complex fluid dynamics in sandwich packings is modeled using a novel approach based on a one-dimensional, steady momentum balance of the liquid and gas phases. The interactions between the three present phases (gas, liquid, and solid) are considered by closures incorporated into the momentum balance. The formulation of these closures is derived from two fluid-dynamic analogies for the film and froth flow patterns. The adjustable parameters in the closures are regressed for the film flow using dry pressure drop measurements and liquid hold-up data in trickle flow conditions. For the froth flow, the tuning parameters are fitted to overall pressure drop measurements and local liquid hold-up data acquired from ultra-fast X-ray tomography (UFXCT). The model predicts liquid hold-up and pressure drop data with an average relative deviation of 16.4 % and 19 %, respectively. Compared to previous fluid dynamic models for sandwich packings, the number of adjustable parameters could be reduced while maintaining comparable accuracy.

Authors: Kara Aziz , Gerçek Hacer Gizem , Özkan Yekta , Çelikkol Sadıç Çağla , Koca Serkan Bilge
Published: September 2023

Objectives

Type 1 diabetes (T1D) causes psychological distress, negatively impacting normal childhood activities. Depression, anxiety disorders, and eating problems are commonly observed in this population.

Methods

The study population consisted of 40 adolescents (22 females and 18 males) who had been diagnosed with T1D and 41 healthy adolescents (21 females and 20 males). The aim of this study was to compare adolescents with T1D to healthy controls in terms of depression, anxiety, and eating problems and subsequently examine the T1D group in relation to the risk of diabetes-specific eating disorders. Eating Attitudes Test (EAT-40), Revised Children’s Anxiety and Depression Scale (RCADS), and Diabetes Eating Problem Survey – Revised (DEPS-R) scales were used to compare the case and control groups.

Results

The case group exhibited significantly higher scores in EAT-40 total score, RCADS parent form major depressive disorder (MDD), social anxiety disorder (SAD), generalized anxiety disorder (GAD), panic disorder (PD), total anxiety score, total scale scores, RCADS child form MDD, PD, and total scale scores compared to the control group. Individuals at high risk of diabetes-specific eating disorder within the case group demonstrated significantly higher RCADS (child and parent form) MDD scores and RCADS parent form separation anxiety (SA) and total scale scores. Binary logistic regression analysis revealed that the RCADS parent form total scale score could predict DEPS-R.

Conclusions

Routine screening of children and adolescents diagnosed with T1D for depression, anxiety, and eating disorder risk may facilitate early detection of possible psychopathologies, allowing for early intervention to address factors that may disrupt treatment adherence. Further longitudinal studies with larger samples are needed to investigate psychopathologies, particularly eating disorders, in children and adolescents with T1D.
Preparation, characterization, and stability of lipid nanoparticles including unsaturated lipids
Authors: Park Yeseul , Park Jin-Won
Published: September 2023

Among the SARS-CoV-2 vaccines developed to date, the mRNA vaccines developed by the Pfizer/BioNTech and Moderna companies have been formulated using saturated lipids, specifically 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC), along with cholesterol. DSPC and cholesterol have the disadvantage of causing sclerosis. Therefore, in this study, lipid nanoparticles (LNPs) were prepared and characterized by replacing DSPC with 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) and excluding cholesterol. The results showed that the DOPC-based LNPs had a smaller diameter (75.67 nm) compared to the previous study and the polydispersity index (PI) indicated a good dispersion homogeneity, suggesting size uniformity. Additionally, the LNPs maintained their size between 57 nm and 152 nm and showed stable PI values (0.330–0.393) throughout the 25 days.

Published: September 2023

A novel three-dimensional coordination compound has been solvothermally synthesized based on a tetracarboxylate ligand H4L (H4L = 1,3,6,8-tetrakis(4-carboxylphenyl)pyrene), Zn2L(H2O)2·2DEF (1) (DEF = N,N′-diethylformamide). Each Zn ion is coordinated by four carboxylate oxygen atoms from four L4− ligands and one oxygen atom from a water molecule to provide a distorted square-pyramidal geometry. Pairs of adjacent Zn cations are bridged by four carboxylate groups of four different L4− ligands to generate a paddle-wheel [Zn2(COO)4(H2O)2] secondary building unit (SBU). Each SUB is further linked to four L4− ligands to give a three-dimensional framework with cds-type (CdSO4-type) topology. The crystal structure has been determined via single-crystal X-ray diffraction, and the compound was characterized by elemental and thermal analysis, infrared spectroscopy, powder X-ray diffraction, and solid-state photoluminescence measurements.

Water pollutants especially alcoholic based aromatic compounds are documented as emergent water pollutants and caused serious health problems for all living organisms. It is a major challenge for all researchers to synthesize effective adsorbents to eliminate these water pollutants. For this purpose, two MOFs were synthesized and characterized using SEM, FTIR, EDX and PXRD techniques. These MOFs exhibited excellent adsorption capacity for resorcinol and adsorption process was spontaneous, endothermic and proceeds with physiosorption as confirmed using thermodynamics data (∆H
ads = 30.473 kJ/mol). Furthermore, separation-factor value was in the range of 0.0238–0.1312 for 30–100 ppm resorcinol concentration which represents that adsorption process was favorable. Langmuir and Pseudo 2nd order Models were best described which represented that chemisorption process also favored due to presence of –OH group and N-atom between adsorbent and adsorbate as well as monolayer adsorption-process is proceeded. Moreover, ion-exchange and electrostatic-interactions are the major interactions which are responsible for adsorption of resorcinol. Along with electrostatic-interactions, ion-exchange, hydrogen-bonding and π–π stacking/interactions are also accountable for adsorptive elimination of resorcinol. In summary we can conclude that MOFs are considered outstanding adsorbents for elimination of water pollutants to purify water, as water is very important for healthy life.

Published: September 2023

The results of investigation of optical excitation, photoluminescence (PL) and cathodoluminescence (CL) spectra in Cr-doped β-Ga2O3 thin films are presented. The broad bands due to the generation of electron-hole pairs and transitions from the 4А2 ground level to the 4Т1 and 4Т2 excited states in Cr3+ ions are observed in the photoexcitation spectra. The R-lines and phonon repetitions of R-lines are observed on the luminescence spectra against the background of a broad structureless band with a maximum around 700 nm, caused by the 4T2 – 4A2 transitions in Cr3+ ions. The crystal field force Dq was determined and the Stokes and anti-Stokes repetitions of R-lines were interpreted.

Published: September 2023

A comparative analysis of the edge absorption spectra measured in the temperature range of 290–470 K for two types of zinc selenide substrates has been carried out. It has been established that the self-absorption edge of pure ZnSe: Yb melt crystals is described by the «crystalline» approximation of the general Urbach rule, which is a consequence of dynamic disordering. In samples doped with ytterbium, at 330 K, a reversible transition from dynamic to static disordering was detected, which is described by the “glassy” approximation of the general Urbach rule.

Published: September 2023

The objective of the current research was to compare oxidative stress markers, metabolic variables and serum amyloid A (SAA) in dairy cows with Staphylococcus aureus subclinical mastitis before and after treatment and to evaluate their correlation with treatment outcome. Oxidative stress biomarkers, including total antioxidant capacity (TAC) and malondialdehyde (MDA) and SAA were measured in milk samples and non-esterified fatty acids (NEFA), glucose, calcium and magnesium were determined in blood serum samples of two groups of cows: 1) S. aureus subclinical mastitis cows with unsuccessful treatment (UST group; S. aureus isolated in bacterial culture and somatic cell count (SCC) ≥ 200,000 cells/mL in milk samples obtained before and after treatment; n=26), and 2) S. aureus subclinical mastitis cows with successful treatment (ST group; negative bacterial culture and SCC < 200,000 cells/mL in milk samples obtained after treatment; n=26). Successful treatment signi­fi­cantly decreased milk SCC and SAA and serum NEFA (P<0.05), while significantly increased serum calcium, magnesium and glucose levels (P<0.05) in ST cows. After unsuccessful treatment, mean milk SAA dropped significantly (P<0.05) while milk TAC and SCC and serum calcium levels increased (P<0.05) in UST cows. The findings of the present study showed that the improvement of negative energy balance (observed as decreased NEFA and increased glucose concentration following successful treatment) might be an important variable for the treatment outcome of S. aureus subclinical mastitis in dairy cows
Evolution of avian infectious bronchitis vaccine viruses reisolated from vaccinated broilers
Authors: Boudaoud A. , Barberis A.
Published: September 2023

Genetic and phenotypic diversity among infectious bronchitis virus (IBVs) is a key element of the epidemiology of avian infectious bronchitis. Virtually, all studies have focused on the evolution of wild viruses. Live-attenuated vaccine strains deserve a special attention. Two strains of IBV, 2T/17 and 16T/17, detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR) in samples from H120 vaccinated chickens showing respiratory signs, were genetically analysed targeting the S1 gene. The total RNA was extracted by the classical Trizol method. The whole S1 gene was amplified in an end-point RT-PCR using a specific primer pair, before being sequenced. The obtained sequences were compared to those of vaccine strains and reference viruses and finally subjected to a phylogenetic analysis. The two isolates turned out to be vaccine strains as evidenced by the monophyletic cluster they formed with the H120 vaccine strain (100% bootstrap). Also, they shared with this vaccine strain 99.60% and 99.47% of nucleotides (nt) for strain 2T/17 and 16T/17 respectively. The sequence alignment revealed, for each of the two strains, one non-synonymous nt substitution outside the hypervariable regions: C56T and T39G leading to two amino acid (aa) substitutions: Alv19Val and Cys13Trp, respectively for the strain 2T/17 and 16T/17. The second hypervariable region of strain 2T/17 displayed 2 nt substitutions at positions 345 and 347, resulting in an aa substitution Lys116Thr. As for 16T/17 strain, it harboured two non-synonymous nt substitutions (T353G and T380G), leading to two aa substitutions: Val118Gly and Met127Arg. The chromatogram analysis revealed minor and major peaks at all positions where nt changes were observed. Nucleotides associated with minor peaks matched with those observed in the sequence of the H120 vaccine strain at the same positions, indicating subpopulation selection. Only the substitution T353G results in a mutation as evidenced by the absence of minor peak at this position. Viral subpopulations contained in IBV live-attenuated vaccines are susceptible to be in vivo selected and emerge as persistent pathotype with reversion to virulence. This draws attention to the need of monitoring the evolution of IBV vaccine strains.

O presente artigo procura analisar uma maneira específica na qual os antigos romanos estabeleceram novos templos e cultos para deuses e deusas estrangeiras, através da consulta dos Livros Sibilinos, uma ação realizada para expiar prodígios que foram reportados.
A terminologia da “compaixão” na Ilíada, de Homero: breve contribuição à semântica de uma emoção
Authors: Maciel Felipe Marques
Published: September 2023

O objetivo deste artigo é investigar o campo semântico da “compaixão” na Ilíada, de Homero, utilizando a metodologia dos campos lexicais, proposta por Michael Clarke (2014), em consonância com métodos próprios da história das emoções, de Barbara Rosenwein (2011). Argumentamos que os principais estudos sobre a compaixão enfocam os termos “éleos” e “oîktos” e seus cognatos, ignorando outros que podem ser importantes para a compreensão de tal condição emocional na poesia homérica, como os verbos “olophýromai” e “oimṓzō”, além de seus termos cognatos. Utilizamos como estudos de casos passagens relacionadas a Zeus e Aquiles, dois personagens centrais no poema, e demonstramos a pertinência da investigação para propósitos narrativos e antropológicos.

The Danube Homeland of the Slavs in the Tale of Bygone Years: A Problem of Interpretation
Authors:   Saint Petersburg State University, Alimov Denis
Published: September 2023

Introduction. The article discusses the image of the ancestral homeland of the Slavs as described in the early 12th century Old-Russian chronicle known as the “Tale of Bygone Years.” Methods and materials. The focus of the article is on the concept of the Danube Slavic land, which, according to the chronicle, was the ancient homeland of the Slavs. In order to elucidate this concept, the author uses elements of historical-semantic analysis of the text and compares its information with data from other sources relevant for the study of this topic. Analysis. Taking into account the heterogeneity of knowledge underlying the chronicle ethnogenetic construction, the author identifies various elements of this knowledge. Results. The author comes to the conclusion that the image of the Danube homeland of the Slavs was not a bookish construction but a reflection of the ethnic realities of the early Middle Ages, when the Carpathian basin was the core area of the Slavic ethnic identity. According to the author, the formation of the idea that the Middle Danube Slavic land was the primary homeland of the Slavs was also the result of the perception of the Slavs as autochthonous inhabitants of Illyricum and Pannonia, which existed in Rome in the time of the Pannonian diocese of Methodius and probably influenced the formation of Slavic ethnogenetic legends through Cyril’s and Methodius’s cultural and ideological legacy.
Essence and content of anti-crisis management in Russia
Authors: Shilenkov Egor
Published: September 2023

The author of the publication reveals the problem of liquidity management and asset valuation during a crisis. These aspects are of particular importance, since their goal is similar: to determine the investment attractiveness of a business and its solvency (both for third-party investors and for self-audit). First of all, the author pays attention to the peculiarities of liquidity management. He emphasizes that a wide range of methods is used to form the liquidity metric. In addition, the author notes that in a crisis situation, attention is also paid to issues related to the implementation of effective working capital management, the purpose of which is to calculate the structure and volume of current assets, the sources from which they are covered, and their relationship relative to each other. According to the theoretical developments of domestic authors in the field of financial management, there are many options for influencing the level of risks. The article provides a list of the main methods widely used in practice in Russia. Further, the author discusses the importance of creating an effective mechanism for anti-crisis management, as well as the high requirements for liquidity management. He reinforces his thoughts with the example of the bankruptcy of Transaero. After that, the author pays attention to the issue of asset management in a crisis period. They identified several effective methods used in the event of a crisis. It is emphasized that asset management takes into account the potential for changes in their market value. In some sectors, the market value of assets can depreciate extremely intensively, while in others, on the contrary, it can increase. According to the author, anti-crisis policy in an unstable economic environment can be reoriented to the use of more rational asset formation tools in the current conditions.

This paper presents a study on the characterization of density as a function of temperature for phase change materials (PCMs). More specifically, in this study we analyze organic alkane PCMs, often called paraffins. PCMs are materials that have the ability to absorb a substantial amount of heat during phase transition from solid to liquid, and therefore prove to be useful in thermal energy storage. The density of paraffin wax PCMs is largely dependent on temperature, and during the phase change process, the density decreases dramatically as the PCM transitions from solid to liquid. Consequently, the PCM experiences dramatic volumetric expansion during this transition. Besides the thermal energy storage uses of PCMs, this volumetric expansion that they exhibit is also used in thermal actuator applications, often referred to as wax motors. While density of PCMs does affect their thermal and mechanical performance, the property is not well-characterized within the literature. In this paper, we examine ten paraffin wax PCMs with varying melting
temperatures and characterize their densities as a function of temperature. This characterization was done using
a piston and cylinder dilatometer test setup within a temperature-controlled thermal chamber that we designed
and validated to the well-characterized density properties of water. The density and temperature relationships were
further analyzed using piecewise linear regression analysis to develop mathematical models of density as it relates to
temperature, which will be useful to those wishing to analyze designs in which PCMs are used, such as in PCM-filled heat sinks.
A MIXED DQ-NEWMARK METHOD FOR DYNAMIC RESPONSE AND STRESS ANALYSIS OF POROUS FG RECTANGULAR PLATES UNDER MOVING LOAD
Authors: Akhzary Ali , Khorshidvand Ahmad Reza
Published: September 2023

In this paper, the stress analysis and dynamic behavior of porous functionally graded rectangular plates under moving
concentrated load when supported on the Winkler-Pasternak model of elastic foundations are considered. The mechanical
properties of functionally graded plates, such as their elasticity modulus and density, are varied in accordance with the power law, while the constant Poisson's ratio is taken into consideration, and porosity is assumed to be classified into two categories: evenly and unevenly distributed. On the basis of first-order shear deformation theory and Hamilton's principle, the theoretical equations of motion and boundary conditions are obtained. The concepts of change of variables, as well as the implementation of the generalized differential quadrature method and the Newmark procedure, have all been used to achieve dimensionless discrete equations. The effects of the volume fraction index, the velocity of the load, the porosity volume fraction and distribution pattern, the boundary conditions, the modulus of the Winkler foundation, and the Pasternak shear layer foundations' stiffness on the displacements and stresses of plates have been investigated.

Published: September 2023

This research presents a constitutive model for the macro scale simulation of masonry structures. The model is containing an orthotropic plane stress assumption, which appears as an appropriate assumption for the in-plane analysis of masonry walls. The material model is based upon damage mechanics, split into tensile and compression parts. The novelty herewith is the consistent mapping of the damage evolution laws. Aim of this research is to develop a simple but accurate constitutive law, suitable to simulate large scale structures and buildings with reasonable computational costs. The developments are presented and compared with available literature examples from laboratory testings.
Equation for time-dependent local scour at pier-like structures with eccentric in-line arrangements
Authors: Nandi Buddhadev , Das Subhasish
Published: September 2023

Excess scour developing around tandem and eccentric piers of side-by-side bridges may aggravate bridge failure. Thinking differently, this combination of pier-like structures may increase scour and shift sediments towards the bank, which may help in self-dredging. Therefore, accurate estimation of temporal scour depth (dst) around such piers has a very high priority nowadays. However, little work has been done in this regard. Most of the previous equations predict dst only for an isolated pier. Here, two to three piers are placed eccentrically in line in addition to isolated piers to derive equations empirically for accurate prediction of dst considering circular, triangular and square pier shapes. The present experimental results for an isolated circular pier are validated using equations from the literature, cross-validated with other published experimental data. Predictive equations are proposed for two to three piers with eccentrically in-line arrangements, taking their intermediate spacings as key variables. These equations are established based on dimensional analysis and non-linear regression. Overall analysis reveals that the estimated temporal scour depths based on the proposed integrated equation are closely within the ±80% accuracy band. The proposed equations can be used to predict temporal scour accurately for selected combinations of piers within the given experimental ranges.

Introduction:The productive and sustainable development in the department of Cauca depends to a large extent on the effective use of information and communication technologies (ICT). However, the institutional framework lacks mechanisms or methods to select investment projects with ICT resources. This situation has become an obstacle to economic growth and the improvement of social conditions in the region. Methods:In this article, the construction of a methodological design, one that allows for the selection and evaluation of projects with ICT resources that contribute to the solidarity economy of Cauca communities, is consolidated. The investigative process used a mixed approach, carrying out a systematic review of academic and political-organizational information, after which proposals and selection criteria used in Cauca in the last 5 years were analyzed.Results:With the information collected and analyzed, a route for the selection and evaluation of projects was compiled. Likewise, user stories were used to create a simulator that materializes the process of selecting and evaluating projects in a more efficient and effective way.Conclusions:In conclusion, the creation of the methodological design, materialized in the simulator, represents a valuable tool for the department of Cauca, since it allows for a rigorous and coherent evaluation of investment projects with ICT resources Originality:Promoting productive growth, the solidarity economy also contributes to sustainable development for the communities of Cauca.Limitations:The sample was limiteddue to the geographical location of the municipalities.

Purpose. Obtaining extracranial diﬀuse tumor foci of glioblastoma in Balb/c Nude mice by implantation of mitochondria isolated from human glioblastoma.

Material and methods. Human glioblastoma mitochondria were isolated using diﬀerential centrifugation in a high speed refrigerated centrifuge. Mitochondrial samples were diluted with 0.9 % NaCl solution to a protein concentration of 3 mg of protein in 0.4 ml of saline. Balb/c Nude mice (N = 6) were intraperitoneally transplanted with freshly isolated glioblastoma mitochondria at the rate of 3 mg of protein per 1 animal in 0.4 ml of physiological solution. Male mice of Balb/c Nude line (N = 4), which were injected once intraperitoneally with 0.4 ml of physiological solution, served as control. All animals were euthanized by guillotine decapitation 17-21 days aﬅer parenteral implantation of mitochondria isolated from glioblastoma.

Results. Speciﬁc changes in the spleen structure were revealed (N = 4): the formation of strands of cells resembling glioblastoma multi-forme was observed in multiple ﬁelds of vision. The initiation of diﬀuse growth of glioblastoma cells in the stromal part of the red pulp of the spleen was evidenced by the expression of GFAP and ki-67, which were also recorded in the tumor preparation of the patient with glioblastoma. Morphological examination of the mesentery and lymph nodes revealed multiple areas with atypical cells resembling glioblastoma multiforme, localized in ﬁbrous septa and sinuses. Stained granules with the corresponding immunohistochemical proﬁle, GFAP and ki-6, were clearly deﬁned in the mesentery and lymph node of a Balb/c Nude mouse (N = 6) aﬅer transplantation of human glioblastoma mitochondria. An additional study of the immunophenotype of cells in the spleen, mesentery, and lymph nodes of Balb/c Nude mice by the generally accepted marker S100 leﬅ no doubt about the induction of malignant growth aﬅer transplantation of mitochondria isolated from human glioblastoma.

Conclusions. Parenteral implantation of mitochondria isolated from human glioblastoma in male Balb/c Nude mice Might cause the growth and development of extracranial foci of glioblastoma in animals.

Breast cancer (BC) is the most common malignant disease. The use of neoadjuvant drug therapy increases the likelihood of achieving a complete pathomorphological response (pCR), leads to an increase in resectability and ablation; helps to determine the sensitivity of tumor cells to chemopreventive agents, thereby improving the patient’s prognosis. Since pathomorphological assessment occurs aﬅer surgery, it is necessary to develop methods for non-invasive response assessment for timely correction of the volume of treatment. One such method is magnetic resonance imaging (MRI). Assessment of the obtained images using texture analysis allows to increase the accuracy of the method both in the control of neoadjuvant treatment and in the assessment of the response to neoadjuvant therapy during preoperative planning.

This article provides an analysis of the literature data on the potential to improve the prognostic value of breast MRI in assessing the complete pathomorphological response to neoadjuvant drug treatment of breast cancer using texture analysis of data.

Authors: Akhverdiev B. D.
Published: September 2023

Purpose of the study. The purpose of the study was to compare the eﬀect of spinal and general anesthesia on the incidence of postoperative complications aﬅer hernioplasty and on the dynamics of the frailty index (FI) in elderly patients with inguinal hernia.

Patients and methods. 78 patients diagnosed with inguinal hernia were involved in the study (average age was 70.1 ± 0.8 years). Patients underwent open hernia repair and Lichtenstein plasty of the posterior wall of the inguinal canal. The patients were divided into two groups depending on the type of anesthesia: spinal anesthesia (SA; N = 65) and general anesthesia (GA; N = 13). At the time of admission, 30 days aﬅer the surgery, the FI was calculated using the Edmonton questionnaire.

Results. In the SA group, 39 patients (60 %) had a FI ≥ 7; 9 patients (13.8 %) had a FI ≥ 9; 8 patients (12.3 %) had a FI ≥ 11; and 9 patients (13.8 %) had the highest FI ≥ 12. At 30 days aﬅer surgery, 20 patients (30.8 %) showed a decrease in FI values (FI from 7 to 9 decreased almost 2-fold). In the GA group, on the day of admission, 6 patients (46.2 %) had FI ≥ 7, 5 (38.5 %) had FI ≥ 9, and 2 (15.4 %) had FI ≥ 11. At 30 days aﬅer surgery, no changes were observed in patients with FI ≥ 7.

Conclusion. In the spinal anesthesia group, urinary retention was predominant among complications, while in patients aﬅer general anesthesia, pulmonary atelectasis prevailed among complications. The use of spinal anesthesia for hernioplasty was accompanied by a decrease in the frailty index within 30 days aﬅer surgery in individuals with a FI ≥ 7. In the GA group, decrease in the index within 30 days aﬅer surgery was observed in patients with FI ≥ 9.
