Self-awareness Regarding Obesity and Specific Therapy in Patients with Overweight or Obesity and Cardiovascular Diseases from Moscow Region

Objective: Despite the proven effectiveness of lifestyle interventions and specific medications in the treatment of obesity, little is known about their use in real-world practice. . Aims: To study the awareness of patients about the problem of overweight/obesity, as well as the clinical practice of non-drug and drug therapy according to the survey Material and Methods: Eligible patients were recruited from the prospective outpatient registry of patients with cardiovascular diseases. The design of the study was a cross-sectional cohort singlecentre. All of the included patients completed a specifically designed questionnaire. The study included 295 patients (mean age 66.8 ± 11.8 years) with a body mass index (BMI) of ≥ 25 kg/m2. One hundred eight (36.6%) individuals were overweight, 124 (42.2%) had first-class obesity, 42 (14.2%) had second-class obesity, and 21 (7.1%) patients had third-class obesity. Results: 252 patients (85.4%) were informed of being overweight/obese, and all of them received non-drug recommendations for the treatment of obesity. Anti-obesity medications (AOM) were recommended only to 25 (8.5%) patients: 3 – overweight, 11 – obesity class I, 6 obesity class II, and 5 – obesity class III. Twenty-one (7.1%) patients took the prescribed medications (84% adherence). The drugs were more often taken by patients with class II and III disease (40.5% and 57.1% of patients, respectively). Overweight (8.5%) and class I obesity (18.0%) patients took these drugs less often (p < 0.0001). Conclusion: The results of the survey have demonstrated good awareness of patients about their obesity/overweight and quite frequent use of non-drug obesity therapy. However, the rate of AOM prescription was extremely low.

E-cigarette use among early adolescent tobacco cigarette smokers: testing the disruption and entrenchment hypotheses in two longitudinal cohorts

ObjectiveUsing longitudinal data from two large-scale cohorts in the UK and USA, we examine whether e-cigarette use steers adolescent early smokers away from tobacco cigarettes (disruption hypothesis) or deepens early...

Baseline protective behavioral strategy use predicts more moderate transdermal alcohol concentration dynamics and fewer negative consequences of drinking in young adults' natural settings.

Test whether frequent protective behavioral strategies (PBS) users report (a) fewer alcohol-related consequences and (b) less risky alcohol intoxication dynamics (measured via transdermal alcohol concentration [TAC] sensor "features") in daily life. Two hundred twenty-two frequently heavy-drinking young adults (Mage = 22.3 years) wore TAC sensors for 6 consecutive days. TAC features peak (maximum TAC), rise rate (speed of TAC increase), and area under the curve (AUC) were derived for each day. Negative alcohol-related consequences were measured in the morning after each self-reported drinking day. Past-year PBS use was measured at baseline. Young adults reporting more frequent baseline PBS use showed (a) fewer alcohol-related consequences and (b) lower intoxication dynamics on average (less AUC, lower peaks, and slower rise rates). Limiting/stopping and manner of drinking PBS showed the same pattern of findings as the total score. Serious harm reduction PBS predicted fewer negative alcohol-related consequences, but not TAC features. Multilevel path models showed that TAC features peak and rise rate partially explained associations between PBS (total, limiting/stopping, and manner of drinking) and consequences. Independent contributions of PBS subscales were small and nonsignificant, suggesting that total PBS use was a more important predictor of risk/protection than the specific types of PBS used. Young adults using more total PBS may experience fewer alcohol-related consequences during real-world drinking episodes in part through less risky intoxication dynamics (TAC features). Future research measuring PBS at the daily level is needed to formally test TAC features as day-level mechanisms of protection from acute alcohol-related consequences.

Comparison of different bone substitutes in the repair of rat calvaria critical size defects: questioning the need for alveolar ridge presentation.

This study aimed to evaluate the effectiveness of biomaterials in bone healing of critical bone defects created by piezoelectric surgery in rat calvaria. Histomorphologic analysis was performed to assess bone regeneration and tissue response. Fifty animals were randomized into five groups with one of the following treatments: Control group (n = 10), spontaneous blood clot formation with no bone fill; BO group (Bio-Oss, Geistlich Pharma; n = 10), defects were filled with bovine medullary bone substitute; BF group (Bonefill, Bionnovation; n = 10), defects were filled with bovine cortical bone substitute; hydroxyapatite group (n = 10), defects were filled with hydroxyapatite; calcium sulfate group (n = 10), defects were filled with calcium sulfate. Five animals from each group were euthanized at 30 and 45 days. The histomorphometry calculated the percentage of the new bone formation in the bone defect. All data obtained were evaluated statistically considering P < .05 as statistically significant. The results demonstrated the potential of all biomaterials for enhancing bone regeneration. The findings showed no statistical differences between all the biomaterials at 30 and 45 days including the control group without bone grafting. In conclusion, the tested biomaterials presented an estimated capacity of osteoconduction, statistically nonsignificant between them. In addition, the selection of biomaterial should consider the specific clinical aspect, resorption rates, size of the particle, and desired bone healing responses. It is important to emphasize that in some cases, using no bone filler might provide comparable results with reduced cost and possible complications questioning the very frequent use of ridge presentation procedures.

Effects of Bipolaris yamadae strain HXDC-1-2 as a bioherbicide against Echinochloa crus-galli in rice and dry fields.

Barnyardgrass (Weed Science Society of America recommended) or Barnyard grass (Britannica recommended) (Echinochloa crus-galli (L.) P. Beauv.) is one of the most problematic and dominant weeds in world agricultural systems, especially in paddy fields, where tillering and grain yield can be reduced by 50-70% because of its competitive pressure. The frequent use of chemical herbicides to control E. crus-galli has led to the evolution of herbicide resistance. Developing bioherbicides using pathogenic fungi to control E. crus-galli could be an alternative option. In a previous study we showed that a strain of Bipolaris yamadae (HXDC-1-2) was promising in controlling gramineous weeds. Here we present a study that evaluated this fungus as a mycoherbicide against E. crus-galli in greenhouse and paddy fields, characterized mycelium growth and conidial production, and examined the infection development. The median effective dose (ED50) and 90% effective dose (ED90) values of microcapsulated B. yamadae strain HXDC-1-2 on E. crus-galli in the greenhouse were 7.17 × 102 and 9.35 × 103 conidia mL-1, respectively. Conidial germination, mycelial growth, and attachment formation occurred on E. crus-galli leaves within 1 to 6 h. The hyphae directly invaded cells and stomata, primarily from the appressorium on the epidermis, and necrotic lesions were observed on the leaf surface within 20 to 24 h. Applied to E. crus-galli plants at 1 × 105 conidia mL-1, the fungus reduced the weed's fresh weight of 75%. B. yamadae strain HXDC-1-2 has the potential to be developed as a bioherbicide against E. crus-galli plants, especially in rice fields. © 2024 Society of Chemical Industry.

Lifestyle Factors Associated With Frequent Recurrent Headaches in Children and Adolescents: A Canadian Population-Based Study.

Lifestyle behaviors have been postulated to affect headache frequency in youth and are often the primary target of self-management recommendations. Our study aimed to assess the association between various lifestyle factors and frequent recurrent headaches in children and youth. Children and adolescents aged 5-17 years were enrolled in a large cross-sectional Canadian population-based health survey, completed on January 31, 2019. Headache frequency was dichotomized into "approximately once/week or less" or ">once/week" (defined as frequent recurrent headaches). The association between frequent headaches and meal schedules, screen exposure, physical activity, chronotype, and frequent substance use/exposure (alcohol, cigarettes, electronic cigarettes, and cannabis) was assessed using both unadjusted logistic regression models and models adjusted for age/sex. Fully adjusted models examined the odds of frequent headaches according to all exposures. Survey design effects were accounted for using bootstrap replicate weighting. There were an estimated nweighted = 4,978,370 eligible participants in the population. The mean age was 10.9 years (95% CI 10.9-11.0); 48.8% were female; 6.1% had frequent headaches. Frequent headaches were associated with older age (odds ratio [OR] = 1.31, 95% CI 1.28-1.34, p < 0.001) and female sex (OR = 2.39, 95% CI 2.08-2.75, p < 0.001). In models adjusted for age/sex, the odds of frequent headaches decreased with meal regularity (adjusted OR [aOR] = 0.90, 95% CI 0.89-0.92, p < 0.001) and increased with later chronotype (aOR = 1.10, 95% CI 1.05-1.15, p < 0.001) and excess screen exposure (≥21 hours vs none in past week: aOR = 2.97, 95% CI 1.53-5.77, p = 0.001); there was no significant association with reported physical activity (aOR = 0.95, 95% CI 0.67-1.34, p = 0.77). In 12- to 17-year-olds, frequent headaches were associated with frequent alcohol use (≥1/wk vs never: aOR = 3.50, 95% CI 2.18-5.62, p < 0.001), binge drinking (≥5 times in past month vs never: aOR = 5.52, 95% CI 2.95-10.32, p < 0.001), smoking cigarettes (daily vs never: aOR = 3.81, 95% CI 1.91-7.62, p < 0.001), using e-cigarettes (daily vs never: aOR = 3.10, 95% CI 2.29-4.20, p < 0.001), and cannabis use (daily vs never: aOR = 3.59, 95% CI 2.0-6.45, p < 0.001). In the entire sample, daily exposure to smoking inside the house was associated with frequent headaches (aOR = 2.00, 95% CI 1.23-3.27, p = 0.005). Several lifestyle behaviors were associated with frequent headaches in children and youth, such as meal irregularity, late chronotype, prolonged screen exposure, and frequent substance use/exposure, suggesting that these are potential modifiable risk factors to target in this population.

Driving and mobile phone use: Work addiction predicts hazardous but not excessive mobile phone use in a longitudinal study of young adults.

Work addiction (WA), characterized by dimensions such as overcommitment, difficulties in detachment from work, and work-life imbalance, is presumed to be associated with increased smartphone usage, even during risky activities like driving. The study investigated the connection between WA and future problematic and hazardous smartphone use, considering personality factors: anxiety, rumination, and worry. A three-wave longitudinal study (N=1,866) was conducted from March to July 2019, June to September 2020, and June to November 2021, involving a representative sample of 18-34-year-old residents in Hungary's capital. The study employed Hungarian versions of the Bergen Work Addiction Scale, Problematic Mobile Phone Use Questionnaire, Ruminative Response Scale, Anxiety subscale of the Brief Symptom Inventory 18, and Penn-State Worry Questionnaire. Additionally, author-developed questions on mobile phone use while driving were included. At baseline, those at risk for WA showed more frequent mobile phone use while driving at both time points 2 and 3 compared to the non-risk group. Path analyses revealed rumination, anxiety at time 1, and worry at time 2 as significant mediators between baseline WA and mobile phone use while driving at time 3. However, when analyzing all three mediators together, only anxiety at time 1 and worry at time 2 remained significant. This study demonstrates that WA predicts future mobile phone use while driving through mediation by anxiety and worry. Our findings add to the growing evidence highlighting the detrimental aspects of WA, emphasizing the need for improved prevention and treatment strategies.

High antibiotic resistance rates in Helicobacter pylori strains in Turkey over 20 years: implications for gastric disease treatment.

Helicobacter pylori (Hp) eradication therapy is crucial for preventing the development of gastritis, peptic ulcers, and gastric cancer. An increase in resistance against antibiotics used in the eradication of Hp is remarkable. This meta-analysis aims to examine the resistance rates of Hp strains isolated in Turkey over the last 20 years against clarithromycin (CLR), metronidazole (MTZ), levofloxacin (LVX), tetracycline (TET), and amoxicillin (AMX) antibiotics. Literature search was carried out in electronic databases, by searching articles published in Turkish and English with the keywords ' helicobacter pylori ' or 'Hp' and 'antibiotic resistance' and 'Turkey'. That meta-analysis was carried out using random-effect model. First, the 20-year period data between 2002 and 2021 in Turkey were planned to be analyzed. As a second stage, the period between 2002 and 2011 was classified as Group 1, and the period between 2012 and 2021 as Group 2 for analysis, with the objective of revealing the 10-year temporal variation in antibiotic resistance rates. In gastric biopsy specimens, 34 data from 29 studies were included in the analysis. Between 2002-2021, CLR resistance rate was 30.9% (95% CI: 25.9-36.2) in 2615 Hp strains. Specifically, in Group 1, the CLR resistance rate was 31% in 1912 strains, and in Group 2, it was 30.7% in 703 strains. The MTZ resistance rate was found to be 31.9% (95% CI: 19.8-45.4) in 789 strains, with rates of 21.5% in Group 1 and 46.6% in Group 2. The overall LVX resistance rate was 25.6%, with rates of 26.9% in Group 1 and 24.8% in Group 2. The 20-year TET resistance rate was 0.8%, with 1.50% in Group 1 and 0.2% in Group 2. The overall AMX resistance rate was 2.9%, 3.8% between 2002-2011, and 1.4% between 2012-2021. Hp strains in Turkey exhibit high resistance rates due to frequent use of CLR, MTZ, and LVX antibiotics. However, a significant decrease has been observed in TET and AMX resistance to Hp in the last 10 years. Considering the CLR resistance rate surpasses 20%, we suggest reconsidering the use of conventional triple drug therapy as a first-line treatment. Instead, we recommend bismuth-containing quadruple therapy or sequential therapies (without bismuth) for first-line treatment, given the lower rates of TET and AMX resistance. Regimens containing a combination of AMX, CLR, and MTZ should be given priority in second-line therapy. Finally, in centers offering culture and antibiogram opportunities, regulating the Hp eradication treatment based on the antibiogram results is obviously more appropriate.

Unlocking maintenance insights in industrial text through semantic search

Maintenance records in Computerized Maintenance Management Systems (CMMS) contain valuable human knowledge on maintenance activities. These records primarily consist of noisy and unstructured texts written by maintenance experts. The technical nature of the text, combined with a concise writing style and frequent use of abbreviations, makes it difficult to be processed through classical Natural Language Processing (NLP) pipelines. Due to these complexities, this text must be normalized before feeding to classical machine learning models. Developing these custom normalization pipelines requires manual labor and domain expertise and is a time-consuming process that demands constant updates. This leads to the under-utilization of this valuable source of information to generate insights to help with maintenance decision support. This study proposes a Technical Language Processing (TLP) pipeline for semantic search in industrial text using BERT (Bidirectional Encoder Representations), a transformer-based Large Language Model (LLM). The proposed pipeline can automatically process complex unstructured industrial text and does not require custom preprocessing. To adapt the BERT model for the target domain, three unsupervised domain fine-tuning techniques are compared to identify the best strategy for leveraging available tacit knowledge in industrial text. The proposed approach is validated on two industrial maintenance records from the mining and aviation domains. Semantic search results are analyzed from a quantitative and qualitative perspective. Analysis shows that TSDAE, a state-of-the-art unsupervised domain fine-tuning technique, can efficiently identify intricate patterns in the industrial text regardless of associated complexities. BERT model fine-tuned with TSDAE on industrial text achieved a precision of 0.94 and 0.97 for mining excavators and aviation maintenance records, respectively.

Pornography usage during adolescence: Does it lead to risky sexual behavior?

Are youths who consume pornography more likely to engage in risky sexual behaviors? Using longitudinal data from the National Study of Youth and Religion and an individual fixed effects strategy, this paper investigates the relationship between pornography use among 13- to 23-year-olds and a range of subsequent risky sexual behaviors. It also estimates a lagged dependent variable model where risky sexual behavior of the previous wave is included as a control. The findings suggest that moderate and frequent pornography use increases the likelihood of engaging in acts such as unprotected sex and having multiple sexual partners. Finally, a heterogeneity analysis by gender reveals that males and females behave differently in response to exposure to pornography, but that is true for only a few indicators of risky sex. The paper's findings provide critical information on determinants of risky sexual behavior and meaningful evidence for the policy debate on government censoring and monitoring online behavior.

Genre and stylistic peculiarities of the political discourse (on the material of Addresses of Heads of states)

The article is dedicated to the comparative analysis of Kazakh, Russian and Bulgarian presidential discourse. Presidential power influences both the domestic and foreign policy of the state. Based on this, there has been a tendency to consider the presidential discourse as an independent trend for the last two decades in Linguistics. The article presents an overview of a number of works devoted to the study of the speeches of Heads of state, the classification of political genres and the discursive approach to the investigation of metaphor, and it identifies the conceptual spheres to be the most active sources of modern political metaphors. The purpose of the work is to determine similarities and dissimilarities in the texts of the Addresses of the Heads of States(Kazakhstan, Russia and Bulgaria), the quantitative analysis and interpretation of linguistic means, as well as the manifestation of the linguistic persona of the leader in the Address. The object of the research is the study of the personal factor in the Address, the patterns of representation of reality by the political figure through the prism of the frequent use of language means. The material of the research is the texts of the Addresses of the Presidents of Kazakhstan, Russia and Bulgaria for 2021-2022. The analysis made it possible to conclude about the high frequency of use of specific types of metaphor in the given historical period. We suppose thatthe construction of semantic models, calculation of the frequent use of linguistic means and analysis of statistical data allow us to show the peculiarities of the implementation of metaphors in the Kazakh, Russian, and Bulgarian political discourse, due to the individual characteristics of the speech of the President’s persona and his ethnocultural representation of the reality.

Perception of undergraduate students of Nigeria’s premier university on the use of emergency remote teaching during Covid-19

This study reports preliminary findings on undergraduate students’ perception of the Emergency Remote Teaching (ERT) at the University of Ibadan, Nigeria, during Covid-19. Proportional to size sampling was used in obtaining the sample size of 366, while respondents were selected using convenience sampling. Data collection was through a structured questionnaire containing both open and closed ended questions and data was collected on the factors - attitude, affect, motivation; perceived behavioural control (accessibility, self-efficacy, ease of use,); and cognitive engagement. Findings showed that students’ positive attitude towards face-to-face learning was significantly higher than towards ERT and correlation analysis showed a relationship between preference for face-to-face learning and struggling with ERT. Also, the average difference in students’ motivation for learning before and after commencement of ERT was not statistically significant. Students reported more frequent use of educational technologies after ERT commenced than before and the difference was statistically significant. Increase was reported in all the self-efficacy and cognitive engagement constructs. Positive changes reported were mainly acquisition of additional hobbies as well as business, social and technology skills. Challenges to online learning included poor power supply, cost of data subscription, network disruptions and distractions from family and friends.

Patterns of Socioeconomic Marginalization among People Who Use Drugs: A Gender-Stratified Repeated Measures Latent Class Analysis.

Socioeconomic factors are important correlates of drug use behaviors and health-related outcomes in people who use drugs (PWUD) residing in urban areas. However, less is known about the complex overlapping nature of socioeconomic conditions and their association with a range of individual, drug use, and health-related factors in men and women who use drugs. Data were obtained from two community-recruited prospective cohorts of PWUD. Using a gender-stratified approach, we conducted repeated measures latent class analyses (RMLCA) to identify discrete latent socioeconomic subgroups. Multivariable generalized estimating equations were then used to identify correlates of class membership. Between June 2014 and December 2018, RMLCA of 9844 observations from 1654 participants revealed five distinct patterns of socioeconomic status for both men and women. These patterns were primarily distinguished by variations in income, material and housing security, income generation activity, exposure to violence, criminal justice involvement, and police contact. Across gender, progressive increases in exposure to multiple dimensions of socioeconomic disadvantage were found to be associated with frequent use of opioids and stimulants, accessing social services, and being hepatitis C virus antibody-positive. Similar but less congruent trends across gender were observed for age, binge drug use, engagement with opioid agonist therapy, and living with HIV. Gendered patterns of multiple and overlapping dimensions of socioeconomic adversity aligned with patterns of frequent drug use and health-related concerns, highlighting priority areas for gender-inclusive, multilevel responses to mitigate health disparities and meet the diverse socioeconomic needs of urban-dwelling men and women who use drugs.

Are they using any strategy to decolonize the curriculum? English lecturers' experiences: Strategies to decolonize the curriculum

AbstractThis article presents the results of an interpretive case study of three lecturers teaching English at a South African University. The purpose of the study was to explore the lecturers' strategies to decolonize the curriculum succinctly. Purposive, with convenient sampling, identified the three most available lecturers. An emailed reflective activity, one-on-one semi-structured interviews, and document analysis were consulted for data generation. Inductive and deductive processes were used to ensure guided analysis of the generated data. The article argues that universities are not doing enough to help lecturers to have relevant strategies to decolonize the curriculum, particularly the English curriculum. This study revealed that the University environment allowed the lecturers to be left without any option other than the frequent use of verbal and habitual strategies in decolonizing the curriculum. Yet, they would prefer the option of using written strategies. As a result, the study copiously recommends that English lecturers use all three levels of strategies (written, verbal and habitual) to decolonize the university curriculum.

Unraveling the mechanism of social media application addiction among college students: the moderating role of self-regulation

PurposeThis study seeks to explore the impact of “fear of missing out” (FOMO) and “psychological enhancement” (PE) on addiction to social media applications, subsequently influencing users' life satisfaction and continuous usage intention.Design/methodology/approachThis research involved the administration of two sets of questionnaires during distinct periods: December 15 to December 30, 2022 and August 26 to September 2, 2023. The participants were college students from three universities in China, and the data collection utilized the “Questionnaire Star” platform. Only responses deemed valid and consistent were included in the subsequent statistical analysis. A total of 1,108 valid samples were used for the final analysis. Analyses including reliability, validity, path analysis, structural equation modeling, mediation effects and moderation effects were conducted using SPSS and AMOS software.FindingsThe study revealed that both FOMO and PE exerted positive influences on users' addiction to social media applications. Furthermore, this addiction was found to have a negative effect on users' life satisfaction while simultaneously contributing positively to their intention to continue using these platforms. The mediating effect of social media application addiction and the moderating impact of self-regulation were also substantiated through the analysis.Research limitations/implicationsFirstly, it is important to note that the research population of this study is limited to college students, which may limit its generalizability and representativeness. Although college students are a group known for their familiarity with and frequent use of smartphones and social media apps, the findings may not fully capture the behaviors of social media app users in other age groups. To enhance the understanding of social media app addiction across different age groups, future studies should consider expanding the research population and conducting multi-group difference analyses. Secondly, while focusing on specific users within a particular region can minimize unexplained variance in model estimation, it may also restrict the broader applicability of the study results. Therefore, future studies should consider testing the research model with diverse groups from different regions and cultural backgrounds. This approach will provide valuable insights into how social media app addiction may vary across various contexts, thereby enriching our understanding of this phenomenon.Practical implicationsOur findings reveal that in the “attention economy” environment shaped by addiction, social media app managers should leverage technology to swiftly and accurately target audiences, attract them to their platforms and cultivate long-term relationships. Encouraging users to develop new beneficial habits through app-specific functions and precise services will foster continuous usage and unlock revenue and marketing opportunities for app companies.Social implicationsDespite the extensive scholarly discourse on social media application addiction, there is a lack of a well-defined framework delineating how addictive user behaviors can be leveraged in the marketing strategies of social media application platforms. The present study seeks to address these gaps, contributing to a better understanding of the formation mechanisms and knowledge systems related to social media application addiction. By investigating the causes and consequences of such addiction, this research offers valuable insights and recommendations for the innovative development of these apps, given their widespread popularity. Concurrently, the study establishes a theoretical basis for the concept that users can mitigate the negative effects of social media addiction by exercising their own self-regulation.Originality/valueAs the functionalities and features of social media apps converge, their individual uniqueness starts to diminish, intensifying the competition among social media companies. This escalating rivalry places higher demands on these companies. This study aims to aid social media app companies in comprehending and analyzing the diverse psychological needs of users. By enriching their platform features and services, leading users towards addiction and gaining an edge in the “Attention Economy” competition. Understanding and catering to users' needs will be instrumental in thriving within this dynamic and evolving attention economy landscape.

Frequent Use of Contingency Management and Opioid Treatment Programs that Provide Treatment for More than Only Opioid Use Disorder

Contingency management is an effective behavioral intervention for treating substance use disorders that provides patients with incentives for objective verification of completed targeted recovery behaviors including abstinence from substances, attending treatment, and medication adherence. Accredited/licensed opioid treatment programs provide effective, medications for opioid use disorder. This study evaluated the prevalence of frequent contingency management use among a national sample of opioid treatment programs in the U.S. ( N = 672). A binary logistic regression model examined factors associated with providing contingency management, including state-level fatal overdoses, number of pharmacotherapies, outpatient treatment, facility ownership, and residential treatment. Most evaluated facilities provided contingency management ( n = 440; 65.5%). Facilities that prescribed more pharmacotherapies, were located in states with high drug overdose death rates, and for-profit (compared to nonprofit) providers were more likely to offer contingency management. Because contingency management effectively treats substance use disorders, contingency management should be offered more broadly across opioid treatment programs.

Adaptive fast Walsh-Hadamard transform for magnetic flux leakage signal of broken wire damage extraction under noise background

ABSTRACT Steel wire rope usually works in harsh environments, making it prone to damage during frequent use. Magnetic flux leakage testing is an important way of non-destructive testing, preventing some major accidents of hoist equipment by identifying the damage to steel wire ropes. Whereas, the harsh environment usually generates noise and results in difficulty in extracting the damage features of the magnetic flux leakage signal, which makes it hard to identify the damage. The fast Walsh-Hadamard transform is widely used in signal processing. The denoising effect depends closely on the transform coefficients. If the transformation coefficients can be adaptively retained, better denoising effects can be achieved. Therefore, we propose the adaptive fast Walsh-Hadamard transform to extract the magnetic flux leakage signal of steel wire rope under noise background. Using the cross-correlation co efficient and the similarity of the greyscale histogram as the indexes, the Fast Walsh-Hadamard transform combines the adaptive particle swarm optimisation to adaptively retain the optimal transformation coefficient and then gets the optimal denoising signal. Meanwhile, compared to wavelet denoising methods, the adaptive fast Walsh-Hadamard transform can effectively improve denoising performance in peak-to-peak reductivity and can be successfully used in steel wire rope damage extraction.

Problematic smartphone use among russian and foreign medical students: prevalence, content consumed, associations with other forms online behavior

Aim of the study was to investigate the prevalence of problematic smartphone use, the characteristics of the content consumed and associations with other forms of online behavior among Russian and foreign medical students. Material and methods. 296 medical students were examined using the online survey method: 219 Russians (main group) and 77 foreigners (comparison group); 107 (36.2 %) boys and 189 (63.8 %) girls; age 20 [18; 21] years (median [lower quartile; upper quartile]). The structure of online behavior was assessed: adaptive, non-adaptive, and pathological (PIU) Internet use; specific forms of PIU: problematic use of computer games and social networks, mixed and undifferentiated form of PIU. The values of the total score of the scales of the applied psychometric questionnaires were determined. The indicators were compared in the general group of subjects, in groups of Russians and foreigners, including gender. Results. Problematic smartphone use is typical for 14.2 % of all surveyed. The share of smartphone addicts is higher among foreigners than among Russians (27.3 and 8.0 %, respectively), both boys and girls. PIU prevailed among foreigners (16.1 and 7.4 %), they are more often dependent on social networks (34.5 and 2.4 %). Foreign women were distinguished by a high incidence of problematic use of computer games (20.0 and 3.6 %) and social networks (25.0 and 3.1 %), as well as a mixed form of PIU (20.0 and 2.5 %). The content consumed by Russians (boys + girls) was dominated by being on social networks (77.6 Russians and 46.7 % foreigners) and listening to music (50.7 and 31.2 %, respectively). Gender differences in content included more frequent use of social networks by Russian students, both boys (81.1 and 48.1 %) and girls (76.5 and 43.5 %); more frequent listening to music by Russian males in comparison with foreign males (66.0 and 29.6 %) and Russian females (66.0 and 45.8 %). Foreign boys use smartphones for games more often than foreign girls, the preoccupation with smartphone games is higher among Russian women as well. Conclusions. The prevalence of problematic smartphone use, the characteristics of the content consumed and associations with other forms of PIU among Russian and foreign students were established. In our opinion, it is necessary to carry out further research aimed at solving an urgent medical and social problem of timely diagnosis of smartphonedependent behavior and prevention of somatic and neuropsychic health disorders associated with it in young people.

Hand eczema: a common diagnosis in everyday practice

Hand eczema is one of the most common dermatoses at the doctor’s office during visits. There is some evidence that the prevalence rates reach almost 15% of the population. This disease greatly affects patients’ quality of life, work activities and other areas of life. The eczema pathogenesis is quite complex and is built up of genetic factors, environmental effects and various irritating agents. Disturbances of skin barrier also plays a significant role in the development of the disease. For example, patients with atopic dermatitis often suffer from hand eczema. Excessive hand hygiene (frequent washing and use of alcohol-based products) also increases the risk of developing this unpleasant dermatosis. Clinical features distinguish acute from chronic eczema. Acute eczema manifests as erythema, oedema, and vesicular rashes. The chronic course is characterized by skin thickening, peeling, erosion and cracks. Exacerbations occur 2 or more times per year. Hand eczema can be divided into irritant, which develops in response to contact with physical, mechanical, and chemical irritants, and allergic, which is provoked by contact with an allergen that induces type IV immune response. It is also common to distinguish protein contact dermatitis, which refers to a subtype of allergic eczema. Traditionally, moisturizers and topical corticosteroids are used for the treatment of hand eczema. Among topical corticosteroids, methylprednisolone aceponate (Advantan®) is especially worth noting. In addition to the pronounced therapeutic effect, the option to use it once a day is an undoubted advantage over many other drugs. This fact has a positive effect on therapy adherence. This topical corticosteroid is well tolerated and highly effective for the treatment of eczematous dermatitis, which is confirmed by many-year experience in using it.
