The article analyzes current trends in the use of artificial intelligence, cognitive technologies, Big Data and other innovations in order to predict the stability of the Russian banking system. The current trends in the development of banking innovations in the context of digitalization of the economy are summarized. Among the research methods used, the Random Forest artificial intelligence system, formed in the Google Collab cloud service in Python, should be noted. A neural network model for predicting the dynamics of bank profits based on the use of the Random Forest (RF – random forest) machine learning model is proposed. The results of the study indicate that, with the average value of the profit of banks for the period 2010-2021. 1126.0416 billion rubles, the mean absolute error (Mean Absolute Error) amounted to 129.96666 billion rubles, or 11.5%, which can be regarded as a good result in conditions of market uncertainty. The analysis showed that current trends are global in nature and lead to qualitative changes in the flow of business processes between consumers of banking services and credit institutions.
Purpose: is to form a model that predicts the value of the target variable – the profit of the banking system using the Random Forest deep learning model, which is an ensemble of “decision trees”. The scientific novelty is to put forward and prove the hypothesis that with the help of the formed artificial intelligence system “Random Forest”, a profit forecast for commercial banks of the Russian Federation can be obtained.
Method or methodology of the work. The work used such research methods as: monographic, analytical, artificial intelligence system – “Random Forest”, as well as comparative analysis. Calculations were performed in XL tables, Google Collab cloud service in Python.
Results. The developed AI-system “Random Forest”, designed to predict the profits of banks, is presented. It is of practical importance to use the results of the Random Forest neural network to predict the development of credit institutions, which makes it possible to solve a major national economic problem - ensuring the stability of the banking system of the Russian Federation. A neural network model for predicting the dynamics of bank profits based on the use of the Random Forest (RF) machine learning model is proposed, which is a machine learning algorithm that consists in using an ensemble (set) of decision trees.
The scope of the results: the financial sector, the banking sector, forecasting and ensuring the sustainable activity of credit institutions in the Russian Federation.
Dental and oral manifestations of coeliac disease - a literature review
Authors: Jakubowska Eliza , Łazicka Patrycja , Tuczyńska Magdalena , Karolak Aleksandra , Jasińska Joanna 
Published: May 2023

Introduction
Coeliac disease is a genetic autoimmune disease of the digestive system. It is caused by permanent intolerance to gluten (a protein contained in wheat, rye, barley), which results in the atrophy of the intestinal villi in the small intestine and deficiency of nutrients in the body. It can also manifest itself with various pathologies within the teeth and oral mucosa.
Aim of the study
The purpose of the study is to present the symptoms of coeliac disease in oral cavity.
Materials and methods
PubMed and Google Scholar medical databases were analyzed, operating with the following keywords: coeliac disease, oral cavity, manifestations, lesions, symptoms, oral health in as many configurations as needed. Twenty-eight related articles published during the last five years (2018-2023) were selected.
Results
In addition to the classic intestinal symptomatology, coeliac disease can also manifest itself in the oral cavity in the form of delayed tooth eruption, enamel defects, MIH, recurrent aphthous stomatitis or xerostomia. The etiology of the changes is still not clear, but studies show that they most likely arise as a result of impaired absorption of vitamins and minerals in the small intestine.
Conclusion
The variety of symptoms of celiac disease makes it a significant diagnostic challenge. It is important to raise awareness among dentists about the symptoms of the disease because a quick diagnosis can prevent many complications.

Published: May 2023

Background Routine blood tests following total shoulder arthroplasty (TSA) cost the British national health system over £65,000 in 2018 without definite evidence of their impact on patients’ outcomes. This study aimed to ascertain whether routine laboratory tests are necessary after elective TSA. Methods A retrospective review of electronic records was completed for 274 patients that underwent TSA in the past six years. In total, 216 patients were eligible for analysis. The primary outcome was intervention rate for abnormal postoperative blood tests. Secondary outcomes were hospital length of stay (LOS), and readmissions at 30 and 90 days. Results In total, 193 patients underwent 216 TSAs; 72% were female, and the mean cohort age was 78 ± 7.2 years. Overall, 136 patients (63%) had an abnormal postoperative blood test, however; only 8 (3.7%) required intervention. The average postoperative drop in haemoglobin (Hb) was 19g/l. In four patients (1.8%) Hb levels dropped to < 80g/l; however, only two (0.9%) were symptomatic and received a red blood cell transfusion. Six patients (2.8%) developed acute kidney injury and did not require haemofiltration. The mean LOS was 3.2 ± 2.9 days. Five patients (2.3%) were readmitted within 30 days and six patients (2.8%) within 90 days. Univariate analysis only showed association between patients with abnormal creatinine and LOS (p < 0.05), and all of these patients had raised preoperative creatinine levels. Conclusions Routine postoperative blood tests are not required as they did not change the clinical outcome in this cohort or the readmission rate, causing unnecessary costs. It is recommended to request postoperative blood tests for patients with raised preoperative creatinine levels.
Paediatric post-COVID-19 hyperinflammatory syndrome mimicking appendicitis: a case series
Authors: Coles V , Yardley I , Hameed S , Brennan K 
Published: May 2023

Introduction A novel hyperinflammatory syndrome has emerged in the paediatric population: paediatric inflammatory multisystem syndrome – temporally associated with SARS-CoV-2 (PIMS-TS). Up to 50% of patients develop shock with cardiac dysfunction but presentation with acute abdominal pain is common and difficult to distinguish from appendicitis. Method Prospective case series of PIMS-TS patients presenting to a single UK tertiary paediatric centre. Results As of 16 September 2020, 89 patients have presented with PIMS-TS to our institution; 19 (21.3%) were referred for surgical review. Pyrexia and acute abdominal pain were seen in all 19 patients. Diarrhoea was reported in 14 (73%) and vomiting in 12 (63%). On examination, eight (42%) had right abdominal tenderness, of which five had right iliac fossa (RIF) peritonism. C-reactive protein (CRP) was universally raised: median 176 (15–463)mg/l. Abdominal imaging was performed in 17 (89%), with 11 undergoing abdominal ultrasonography (65%) and 8 abdominal computed tomography (47%); two required both. Findings included nonspecific features of inflammation in the RIF. Eight patients (42%) had an abnormal echocardiogram at admission. Two (10%) patients, with classical signs and symptoms of appendicitis, underwent appendicectomy without radiological imaging and were subsequently diagnosed with PIMS-TS. During the same period, 18 patients underwent appendicectomy for histologically confirmed appendicitis. Serum CRP and ferritin levels were significantly higher in the PIMS-TS cohort compared with children with appendicitis. Conclusions PIMS-TS is a novel paediatric condition that may mimic appendicitis. It should be considered in patients presenting with abdominal pain to avoid unnecessary surgery in children at risk of cardiovascular instability.

Published: May 2023

Introduction Men with gynaecomastia are routinely referred to breast clinics, yet most do not require breast surgical intervention. The aim of this study was to assess the impact of a novel point-of-care gynaecomastia decision infographic in primary care on the assessment, management and referral practices to tertiary breast surgical services. Methods A study was carried out of male patient referrals from primary care in Greater Manchester to a tertiary breast centre between January and March in 2018–2020. Referral patterns were compared before and after the infographic went live in general practices in Greater Manchester in January 2020. Data were collected for gynaecomastia referrals, including aetiology, investigation and management. Results In total, 394 men were referred to a tertiary breast centre from 163 general practices, of which 271 (68.8%) had a diagnosis of gynaecomastia. Use of the decision infographic by primary healthcare providers was associated with a decrease in male breast referrals with gynaecomastia (79.6% to 62.0%). Fewer gynaecomastia patients were referred with a benign physiological or drug-related cause after implementation of the infographic (52.2% vs 41.8%). Only 10 (3.7%) patients with gynaecomastia underwent breast surgery during the study period. Conclusion Implementation of a gynaecomastia infographic in primary care in Manchester was associated with a reduction in gynaecomastia referrals to secondary care. We hypothesise that implementation of the infographic into primary care nationally may potentially translate to hundreds of patients receiving more specialty-appropriate referrals, improving overall management of gynaecomastia. Further study is warranted to test this hypothesis.

IntroductionWe assessed the practice of surgeons regarding venous thromboembolism (VTE) chemical prophylaxis for total hip replacement (THR) and total knee replacement (TKR), before and after issuing of updated National Institute for Health and Care Excellence (NICE) guidance in 2018.MethodsA survey, circulated through the British Hip Society and regional trainee networks/collaboratives, was completed by 306 UK surgeons at 187 units. VTE chemical prophylaxis prescribing patterns for surgeons carrying out primary THR (n=258) and TKR (n=253) in low-risk patients was assessed after publication of 2018 NICE recommendations. Prescribing patterns before and after the NICE publication were subsequently explored.ResultsFollowing the new guidance, 34% (n=87) used low-molecular-weight heparin (LMWH) alone, 33% (n=85) aspirin (commonly preceded by LMWH) and 31% (n=81) direct oral anticoagulants (DOACs: with/without preceding LMWH) for THR. For TKR, 42% (n=105) used aspirin (usually monotherapy), 31% (n=78) LMWH alone and 27% (n=68) DOAC (with/without preceding LMWH). NICE guidance changed the practice of 34% of hip surgeons and 41% of knee surgeons, with significantly increased use of aspirin preceded by LMWH for THR (before=25% vs after=73%; p<0.001), and aspirin for TKR (before=18% vs after=84%; p<0.001). Significantly more regimens were NICE guidance compliant after the 2018 update for THR (before=85.7% vs after=92.6%; p=0.011) and TKR (before=87.0% vs after=98.8%; p<0.001).ConclusionOver one-third of surveyed surgeons changed their VTE chemical prophylaxis in response to 2018 NICE recommendations, with more THR and TKR surgeons now compliant with latest NICE guidance. The major change in practice was an increased use of aspirin for VTE chemical prophylaxis.
Establishing the shadowline: the border between legally acceptable and unacceptable standards of surgical practice
Authors: Ricketts D , O’Brien Aidan , Patterson M , Phadnis J 
Published: May 2023

Introduction Our study investigated how the standard of surgical care is assessed within the English and Welsh litigation process. The ‘shadowline’ represents the dividing line between acceptable and unacceptable standards of care. Our hypothesis was that different assessors risk adopting materially different interpretations regarding the acceptable standard of care. Any variation in the interpretation of where the shadowline falls will create uncertainty and unfairness to surgeons and patients alike. Methods We summarised the legal literature and suggested the factors affecting the assessment of surgical standards. We illustrated our findings on distribution curves. Results There was a risk that the shape of the curve and the location of the shadowline may vary according to the assessor. Importantly, a gap may have developed between the legal and clinical shadowlines in respect of the consenting process. Discussion and conclusion We suggested how a gap between the surgical and legal shadow lines could be narrowed. Clinical governance, balanced literature and realistic expert assessments were all part of the solution.
Protocol for a systematic review of long-term physical sequelae and financial burden of multidrug-resistant and extensively drug-resistant tuberculosis
Authors: Akalu Temesgen Yihunie , Clements Archie C. A. , Baraki Adhanom Gebreegziabher , Alene Kefyalew Addis 
Published: May 2023

Introduction
Multidrug resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) are major public health threats that are significant causes of physical sequelae and financial consequences for infected people. Treatment for MDR- and XDR-TB are more toxic and take longer duration than for drug-susceptible-TB. As a result, the long-term sequelae are thought to be more common among patients with MDR- and XDR-TB than drug-susceptible-TB, but this is yet to be quantified. Hence, the aim of this systematic review and meta-analysis is to quantify the global burden and types of long-term physical sequelae and financial burden associated with both MDR- and XDR-TB.

Method and analysis
We will search CINHAL, MEDLINE, Embase, Scopus, and Web of science for studies that report physical and financial sequelae associated with rifampicin-resistant (RR), MDR- and XDR-TB or their treatments. The search will be conducted without time, language, and place restrictions. A random-effects meta-analysis will be conducted to estimate the pooled prevalence of each physical sequela. Heterogeneity will be measured using the Higgins I2 statistics. We will assess publication bias visually using the funnel plot and statistically using Egger’s test. Adjustments for publication basis will be made using Tweedie’s and Duval Trim and Fill analysis.

Ethics and dissemination
Since the study is based on published evidence, ethics approval is not required. The findings of the systematic review will be presented at various conferences and will be published in a peer-reviewed journal.

Protocol registration
The protocol is published in the PROSPERO with registration number CRD42021250909.
Финансовые и инструментальные трансферты в семьях пожилых респондентов в России и Эстонии: есть ли этнокультурные различия?
Authors: Синявская Оксана Вячеславовна , Козлов Владимир Александрович , Гудкова Татьяна Борисовна 
Published: May 2023

В рамках исследования рассматривается обмен как финансовыми (денежные средства или их близкие эквиваленты), так и инструментальными (помощь в уходе или по хозяйству) трансфертами пожилых респондентов с другими членами расширенной семьи, проживающими или не проживающими с ними, а также особенности ухода пожилых респондентов за внуками.
Авторы опираются на базу данных международного исследования SHARE, проведенного в России в 2021 г. и регулярно проводимого в Эстонии (анализируется волна 2015 г.), и с использованием бинарной логистической регрессии анализируют факторы получения и передачи трансфертов респондентами 50 лет и старше.
Отталкиваясь от ранее проведенных в других странах исследований и учитывая ограничения данных, авторы работы предполагали увидеть этнические различия в обменах финансовыми ресурсами в большей степени, чем инструментальной поддержкой; в получении денежных трансфертов — больше, чем в их передаче. Результаты проведенного исследования отчасти подтвердили сформулированные в статье гипотезы, выявив слабое и неустойчивое влияние этнической принадлежности на включенность людей старшего возраста в межсемейные обмены. Только при контроле прочих факторов (включая образование и особенно доход), принадлежность к этнической группе, отличной от доминирующей в стране, повышает вероятность участия в обмене (как передаче, так и получении) финансовыми трансфертами, но за, редким исключением, не оказывает значимого влияния на вероятность участия в обмене инструментальными трансфертами и совсем не дифференцирует уход за внуками.

Abstract
With the rapid development of smart wearable devices and the urgent demands for new energy resources, fibrous flexible power supply units had attracted a lot of interest. Here, we reported the fabrication of polylactic acid (PLA) piezoelectric nanofibrous yarn-based fabric through conjugated electrospinning and weaving process. Five kinds of PLA yarns including poly(l-lactide) (PLLA), poly(d-lactide) (PDLA), PLLA positive/PDLA negative, PDLA positive/PLLA negative, and PLLA/PDLA mixture (1:1 w/w) ones were prepared and investigated. Among these, the PLLA/PDLA yarn had more uniform and oriented structure with 301 MPa tensile strength, which could meet the requirement of weaving. A 4 cm × 4 cm woven PLLA/PDLA fabric could provide a maximum current of 90.86 nA and a voltage of 8.69 V under 5 N force, and the piezoelectricity could be enhanced by the fabric area and the applied force. This approach may be helpful for the design of wearing generators.
Introduction: language contact and linguistic dynamics – speakers, speaker groups, and linguistic structures
Authors: Winter-Froemel Esme , Ellena Sandra , Goldschmitt Stefanie 
Published: May 2023

Abstract
The introductory paper to the special issue summarises key aspects of contact-related linguistic dynamics such as the communicative interfaces of modern complex societies, the multi-layered textual and discoursal repertoire of their speaker groups and the role of the speakers’ cognitive mechanisms, social identity, and interactional strategies in settings of language contact. Giving an overview of the contributions, it aims to connect classic topics of language contact research with recent theoretical and methodological approaches investigated in the papers, and to highlight interconnections and interdisciplinary links that can stimulate further research on linguistic variation and change.

Abstract
This study focused on testing manufactured silver nanoparticles (AgNPs) against the malaria pathogen Plasmodium falciparum and the malaria vector Anopheles stephensi using the plant filtrate from Madhuca longifolia. The M. longifolia leaf extracts were used to synthesize the AgNPs, which were then subjected to several physicochemical methods to determine their characteristics. To evaluate the effectiveness of the green produced AgNP therapy, the mosquitocidal activity of A. stephensi, cytotoxicity assay in Vero cells, and antiplasmodial activity assay were performed. The larval and pupal toxicity of biosynthesized AgNPs against the malarial vector A. stephensi is 90% promising in laboratory settings at low dosages (10 ppm). When tested on African green monkey kidney cells, the cytotoxic effect of biosynthesized materials was found to be inappropriately damaging up to 100 g·mL−1. The antimalarial efficacy of AgNPs was evaluated against P. falciparum strains. The parasites that were restrained by AgNPs at 100 ppm had the highest parasitemia restraint rate (80.4%). AgNPs then showed significant in vitro antimalarial activity against P. falciparum. Our findings suggested that the biosynthesized AgNPs might function as a novel antimalarial agent that is both safer for the environment and a barrier to infections spread by mosquitoes.

Abstract
Zr-metal-organic frameworks (Zr-MOFs) were prepared by a solvothermal method and characterized by X-ray diffraction, scanning electron microscopy, and thermogravimetry. Zr-MOFs were used to remove doxycycline hydrochloride (DOC) from wastewater. According to the experimental results, the maximum adsorption capacity of DOC by Zr-MOFs within 5 h was 148.7 mg·g−1. From the pseudo-second-order kinetics model, all R
2 values were greater than 0.99, which proved that the adsorption of DOC by Zr-MOFs was consistent with practice. According to the Freundlich isotherm model, the adsorption of DOC by Zr-MOFs proceeded via multilayer adsorption. The aforementioned results show that Zr-MOFs have good application prospects for removing DOC from wastewater.
