Authors: Yaskevich Natalia A. , Lysakov Alexey S. , Yaskevich Roman A. , Moskalenko Olga L. 
Published: May 2023

The purpose of the study. To evaluate the role of chronobiological personality type in the formation of Internet-addictive behavior in schoolchildren.
Materials and methods. The study involved 25 students of both sexes of the 6th grade of secondary school No. 84 in Krasnoyarsk. The chronobiological personality type was determined using the Morningness-Evningness Questionnaire. The Chen Internet addiction Scale was used to assess the level of Internet addiction.
Results. The most common chronobiological type among students was the daytime chronotype. A pronounced and stable pattern of Internet addictive behavior on the CIAS scale was detected in 8,0% of the surveyed schoolchildren, among whom there were only girls. The frequency of gaming addiction was higher in boys, while the frequency of social media addiction was 3 times higher among girls compared to boys. Internet addiction was observed mainly in adolescents with a daytime chronotype. The frequency of gambling addiction was twice as high among the representatives of the evening chronotype, while dependence on social networks was twice as common among schoolchildren of the daytime chronobiological type.
Conclusion. It was found that Internet addiction was observed mainly in students with a daytime chronobiological type.
Text-Forming Repetitions in Intercultural Communication: Chinese-Russian Correspondences
Authors: Ma Yuxin 
Published: May 2023

The success of intercultural communication depends largely on how accurately the communicative goal of the speaker is expressed. Means that contribute to the communicative goal are nationally specific, so they can vary significantly in the texts of intercultural communication. The object of scientific observation in this article is textual repetitions of different types and ways of their expression in the translation and the original text.
The aim of this study is to identify the communicative functions and the specificity of textual repetitions, used in the Chinese and Russian texts of the journalistic genre.
The material of this research was the report delivered by the Chinese Presi-dent Xi Jinping at the 20th National Congress of the Communist Party of China on October 16, 2022, and its Russian version. The article focuses on the intercultural features of the elements of cohesion in the texts of intercultural communication in Chinese and Russian.
The result of the study is to identify the types of communicative tactics in the transfer of comparable information in the texts in Chinese and Russian: correspondence, incomplete correspondence and inconsistency. It is demonstrated that in the translation of the repetitions the Russian-speaking text to a large extent corresponds to the original, preserves the text-forming connections created by these repetitions, but has national specificity in the stylistic processing of the original.
Work-related musculoskeletal pain and discomfort in laparoscopic surgeons: an international multispecialty survey
Authors: Dixon F , Vitish-Sharma P , Khanna A , Keeler BD 
Published: May 2023

Introduction As laparoscopic surgery is used more widely across the globe and within multiple surgical specialties the potential impact on surgeons is yet to be fully quantified. Maintenance of uncomfortable body positions may lead to work-related musculoskeletal disorders (WMSD) in surgeons, with potential knock-on effects. Methods An international open online survey of multispecialty laparoscopic surgeons was carried out, designed and reported in accordance with the CHERRIES checklist for internet e-survey research. There was no paid advertising and no incentives offered. Results A total of 259 surgeons from 9 specialties and 32 countries answered the survey, with 90% reporting pain attributable to performing laparoscopic surgery. All training grades were represented. Longer average operative duration and a greater number of years in practice were both associated with a significantly higher prevalence of pain. Surgeons with a pre-existing injury were significantly more likely to report pain than those without. Twenty per cent of surgeons would consider early retirement owing to pain. Conclusions The impact on surgeons of performing laparoscopic surgery is significant, even given the limitations of an open survey. Innovations such as robotic surgery and improved ergonomic education may reduce the incidence of WMSD in surgeons, to mitigate both the personal effects on surgeons and the wider effect on the future surgical workforce.

Published: May 2023

When a pulsed laser cleans a glass insulator, the laser power, scanning speed, and repetition frequency affect the laser-cleaning effect. Herein, we considered glass insulators and their surface contaminations as objects, established a finite element model, analyzed the influence of these parameters on the temperature and stress fields, and explored the optimal cleaning parameters for glass insulator surface contamination. In addition, a laser test platform was constructed to verify the cleaning effect. The results indicated that the difference in the cleaning effect was negligible for lasers at repetition frequencies of 10–75 kHz. When the power increased, the scanning speed decreased and the temperature of the fouled layer increased. When the power was 60–70 W and the scanning speed was 240 mm/s, the equivalent tensile stress did not exceed the tensile strength of the insulator. The ablation reaction can remove the fouling part, and the tensile stress can overcome the adhesion force generated between the dirt and glass insulator to achieve effective cleaning. Experiments confirmed that the surface dirt removal rate of glass insulators can be approximately 99% at 60–70 W (laser power) and 240 mm/s (scanning speed).

Authors: Norrbäck Mattias , Neovius Martin , Ottosson Johan , Näslund Ingmar , Bruze Gustaf 
Published: May 2023

Background
The personal economic impact of bariatric surgery is not well-described.

Objectives
To examine earnings and work loss from 5 years before to 5 years after bariatric surgery compared with the general population.

Setting
Nationwide matched cohort study in the Swedish health care system.

Methods
Patients undergoing primary bariatric surgery (n = 15,828) and an equal number of comparators from the Swedish general population were identified and matched on age, sex, place of residence, and educational level. Annual taxable earnings (primary outcome) and annual work loss (secondary outcome combining months with sick leave and disability pension) were retrieved from Statistics Sweden. Participants were included in the analysis until the year of study end, emigration or death.

Results
From 5 years before to 5 years after bariatric surgery, earnings increased for patients overall and in subgroups defined by education level and sex, while work loss remained relatively constant. Bariatric patients and matched comparators from the general population increased their earnings in a near parallel fashion, from 5 years before (mean difference -$3,489 [95%CI -3,918 to -3,060]) to 5 years after surgery (-$4,164 [-4,709 to -3,619]). Work loss was relatively stable within both groups but with large absolute differences both at 5 years before (1.09 months, [95%CI 1.01 to 1.17]) and 5 years after surgery (1.25 months, [1.11 to 1.40]).

Conclusions
Five years after treatment, bariatric surgery had not reduced the gap in earnings and work loss between surgery patients and matched comparators from the general population.

Published: May 2023

Background
Uterine Carcinosarcomas (UCS) are a rare type of cancer composed of an admixture of high-grade carcinomatous and sarcomatous elements. Clinicopathological prognostic factors in UCS are well established, but studies that approach the impact of biomarkers in this unusual disease are scarce. The study objective was to evaluate the prevalence and prognostic impact of a panel of prominent biomarkers in uterine carcinosarcoma (UCS) using an immunohistochemical characterization with four biomarkers.

Methods and findings
The internal database of a single Brazilian institution was carefully explored to select women diagnosed with UCS who were submitted to surgery and postoperative chemotherapy with carboplatin and paclitaxel between January 2012 and December 2017. Tissue microarrays containing UCS samples were evaluated by immunohistochemistry for L1CAM, CDX2, p53 and microsatellite instability markers. A total of 57 cases were included. The mean age was 65.3 years (standard deviation, SD 7.0). L1CAM was negative (score 0, no staining) in 27 (47.4%) patients. Of L1CAM-positive, 10 (17.5%) showed weak (score 1, <10%), 6 (10.5%) showed moderate (score 2, between 10–50%), and 14 (24.6%) showed strong L1CAM staining (score 3, ≧50%). dMMR occurred in 3 (5.3%) cases. The p53 was aberrantly expressed in 15 (26.3%) tumors. CDX2 was positive in 3 (5.3%) patients. The three-year progression-free survival (PFS) rate in the general population of the study was 21.2% (95% CI: 11.7–38.1) and the three-year overall survival (OS) rate was 29.4% (95% CI: 18.1–47.6). By multivariate analysis, the presence of metastases and CDX2-positive were significantly associated with poorer PFS (p < 0.001 and p = 0.002, respectively) and OS (p < 0.001 and p = 0.009, respectively).

Conclusion
The strong influence of CDX2 on prognosis requires further investigation. Biological or molecular variability may have impaired the assessment of the impact of the other markers on survival.
The effect of angiotensin converting enzyme gene insertion/deletion polymorphism on anthropometric and biochemical parameters among hypertension patients: A case-control study from Northwest Ethiopia
Authors: Birhan Tsegaye Adane , Molla Meseret Derbew , Tesfa Kibur Hunie 
Published: May 2023

Introduction
The angiotensin-converting enzyme (ACE) gene polymorphism has recently been linked with altered anthropometric and biochemical parameters in hypertensive patients. However, these links are still poorly understood and there is scarce evidence on the topic. Therefore, this study aimed to assess the effect of ACE gene insertion/deletion (I/D) polymorphism on anthropometric and biochemical parameters among essential hypertension patients at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia.

Materials and methods
A case-control study with 64 cases and 64 controls was conducted from October 07, 2020, to June 02, 2021. The anthropometric measurements, biochemical parameters, and ACE gene polymorphism were determined using standard operating procedures, enzymatic colorimetric method, and polymerase chain reaction, respectively. A one-way analysis of variance was used to determine the association of genotypes with other study variables. P value < 0.05 was regarded as statistically significant.

Result
The systolic/diastolic blood pressure and blood glucose level (P-value<0.05) were significantly higher among study hypertensive patients with the DD genotype. However, anthropometric measures and lipid profiles of cases and controls were not associated with ACE gene polymorphism (P-value>0.05).

Conclusion
The DD genotype of the ACE gene polymorphism was found to have a significant association with high blood pressure and blood glucose levels in the study population. Advanced studies with a considerable sample size may be needed to utilize the ACE genotype as a biomarker for the early detection of hypertension-related complications.

There are few established easy-to-perform exercise protocols with evidence-based effects for individuals with type 2 diabetes (T2D). A unique exercise regimen, interval walking training (IWT), has been reported to be beneficial for improving metabolic function, physical fitness and muscle strength in adults of overall health. This pilot study aims to demonstrate descriptive statistics of IWT adherence and changes in various data before and after the intervention of IWT in adults with T2D, perform statistical hypothesis testing, and calculate effect sizes. We performed a single-arm interventional pilot study with IWT for 20 weeks. We enrolled 51 participants with T2D aged 20–80 years with glycohemoglobin (HbA1c) levels of 6.5–10.0% (48–86 mmol/mol) and a body mass index of 20–34 kg/m2, respectively. The target was 60 min/week of fast walking for 20 weeks. The participants visited the hospital and were examined at 4-week intervals during this period. Between the start of IWT and after 20 weeks, we measured and evaluated changes in glucose and lipid metabolism data, body composition, physical fitness, muscle strength, dietary calorie intake, and daily exercise calories. All included participants completed IWT, with 39% of them reaching the target length of fast walking over 1,200 minutes in 20 weeks. In the primary outcome, HbA1c levels, and in the secondary, lipid metabolism and body composition, no significant changes were observed except for high-density lipoprotein cholesterol (HDL-C) (from 1.4 mmol/L to 1.5 mmol/L, p = 0.0093, t-test). However, in the target achievement group, a significant increase in VO2 peak by 10% (from 1,682 mL/min to 1,827 mL/min, p = 0.037, t-test) was observed. Effect sizes were Cohen’s d = 0.25 of HDL-C, -0.55 of triglyceride, and 0.24 of VO2 peak in the target achievement group, which were considered to be of small to medium clinical significance. These results could be solely attributed to IWT since there were no significant differences in dietary intake and daily life energy consumption before and after the study. IWT could be highly versatile and was suggested to have a positive effect on lipid metabolism and physical fitness. In future randomized controlled trial (RCT) studies, the detailed effects of IWT, focusing on these parameters, will be examined.
Trial registration: This trial was registered with the Japanese University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR: Usefulness on interval walking training in patients with type 2 diabetes. 000037303).

Published: May 2023

Background
Equine neonatal sepsis can be challenging to diagnose and prognosticate. Neutrophil gelatinase-associated lipocalin (NGAL), a new marker of renal damage and inflammation, can potentially be helpful.

Objectives
To evaluate NGAL in neonatal foals with sepsis, and assess its relation to outcome.

Animals
Foals ≤ 14 days, with admission blood analysis and stored serum.

Methods
NGAL was measured on stored serum from 91 foals. Foals were scored for sepsis and survival and categorized according to sepsis status (septic, sick non-septic, healthy, and uncertain sepsis status) and outcome groups (survivors and non-survivors). The septic foals were further sub-categorized according to severity (normal sepsis, severe sepsis and septic shock). A Kruskal-Wallis test was used to compare serum NGAL concentrations in survivors and non-survivors, in the sepsis status groups, and in the sepsis severity groups. Optimal cut-off values for serum NGAL concentrations to diagnose sepsis and outcome were determined with receiver operating characteristic (ROC) curves. NGAL was compared to creatinine and SAA.

Results
Median serum NGAL concentrations were significantly higher in septic than non-septic foals. However, serum NGAL concentrations did not differ between sepsis severity subgroups. Serum NGAL concentrations were significantly lower in survivors than in non-survivors. Optimal cut-off values of serum NGAL concentrations were 455 μg/L (sensitivity 71.4%, specificity 100%) and 1104 μg/L (sensitivity 39.3%, specificity 95.2%) for predicting sepsis and non-survival, respectively. NGAL correlated to SAA, but not to creatinine. NGAL performed similarly to SAA to diagnose sepsis.

Conclusion
Serum NGAL concentrations may be useful for diagnosing sepsis and predicting outcome.

Authors: Jo Eun-Jung , Lee Young Uk , Kim Ahreum , Park Hye-Kyung , Kim Changhoon 
Published: May 2023

Background
The prevalence of multiple chronic conditions (MCC), defined as several coexisting chronic conditions, has increased with the aging of society. MCC is associated with poor outcomes, but most comorbid diseases in asthma patients have been evaluated as asthma-associated diseases. We investigated the morbidity of coexisting chronic diseases in asthma patients and their medical burdens.

Methods
We analyzed data from the National Health Insurance Service-National Sample Cohort for 2002–2013. We defined MCC with asthma as a group of one or more chronic diseases in addition to asthma. We analyzed 20 chronic conditions, including asthma. Age was categorized into groups 1–5 (< 10, 10–29, 30–44, 45–64, and ≥ 65 years, respectively). The frequency of medical system use and associated costs were analyzed to determine the asthma-related medical burden in patients with MCC.

Results
The prevalence of asthma was 13.01%, and the prevalence of MCC in asthmatic patients was 36.55%. The prevalence of MCC with asthma was higher in females than males and increased with age. The significant comorbidities were hypertension, dyslipidemia, arthritis, and diabetes. Dyslipidemia, arthritis, depression, and osteoporosis were more common in females than males. Hypertension, diabetes, COPD, coronary artery disease, cancer, and hepatitis were more prevalent in males than females. According to age, the most prevalent chronic condition in groups 1 and 2 was depression, dyslipidemia in group 3, and hypertension in groups 4 and 5. Older age, low income, and severe disability were independent risk factors for MCC in patients with asthma. The frequency of asthma-related medical system use and asthma-associated costs increased with increasing numbers of coexisting chronic diseases.

Conclusion
Comorbid chronic diseases in asthma patients differed according to age and sex. The asthma-related-medical burdens were highest in patients with five or more chronic conditions and groups 1 and 5.

Objetivo: escribir y analizar el efecto de la infección por el virus SARS-CoV-2 sobre la movilización de células en donantes de precursores hematopoyéticos que acudieron a la unidad de trasplante de precursores hematopoyéticos de una institución médica de alta complejidad en Medellín, Colombia. Métodos: estudio transversal retrospectivo analítico basado en registros médicos de pacientes sometidos a trasplante de médula ósea en una entre marzo de 2020 y marzo de 2021.Resultados: de 64 donantes y receptores de células hematopoyéticas, el 22.2 % de los receptores con antecedentes positivos de infección del donante tuvieron fracaso del injerto de granulocitos en comparación con el 9.1 % de los receptores sin estos antecedentes; no hubo diferencia en la tasa de mortalidad. La mediana de células CD34 movilizadas en población donante con antecedente de infección fue de 5 437 965 [RIC 5 070 714 – 7 215 985], similar a los donantes sin antecedente (Mediana de 5 976 773 [RIC 5 046 689 – 7 276 463]) sin encontrar diferencias (p=0.28).Conclusiones: no es posible determinar que la infección por SARS-CoV-2 genere cambios en las células que se movilizan de un donante de células madre hematopoyéticas por lo demás sano, con base en el análisis estadístico que realizamos, no creemos que los datos varíen si se amplía la población estudio, sin embargo se requieren más estudios prospectivos en el futuro.
