BackgroundMedical staff play a crucial role in delivering healthcare services, especially during epidemics of infectious diseases such as coronavirus disease 2019 (COVID-19). However, there is a growing issue of burnout and low wellbeing among this group. While it is widely recognized that burnout has a negative impact on subjective wellbeing, the exact relationship between the two is not yet completely understood. The purpose of this study is to explore the chain mediating role of psychological capital and perceived social support between burnout and subjective wellbeing among medical staff.MethodsUsing the convenient sampling method, 604 medical staff were selected for a cross-sectional study. All participants completed a self-report questionnaire that collected demographic information, as well as data from the Maslach Burnout Inventory-Human Services Survey, General Wellbeing Schedule, Psychological Capital Questionnaire, and Perceived Social Support Scale. SPSS 27.0 and SPSS PROCESS macro were used for data analysis.ResultsThere was a significant correlation between burnout, psychological capital, perceived social support, and subjective wellbeing (p &lt; 0.01). Burnout not only has a direct negative impact on the subjective wellbeing of medical staff (effect: −0.2045; Bootstrap 95%CI: −0.2506, −0.1583), but also exerts an indirect influence on subjective wellbeing through three pathways: the independent mediating effect of psychological capital (effect: −0.0481; Bootstrap 95%CI: −0.0876, −0.0109), the independent mediating effect of perceived social support (effect: −0.0092; Bootstrap 95%CI: −0.0203, −0.0003), and the chained mediating effect of psychological capital and perceived social support (effect: −0.0092; Bootstrap 95%CI: −0.0183, −0.0019).ConclusionHigh burnout in medical staff can impair the level of psychological capital, leading to diminished perceived social support and ultimately reduced subjective wellbeing. The findings of this study contribute to understanding the potential pathways between burnout and subjective wellbeing and provide preliminary data support for developing strategies to improve the mental health of medical staff.

Published: June 2024

BackgroundPrevious observational studies have shown a correlation between leisure sedentary behaviors (LSB) and physical activity (PA) with the incidence of obstructive sleep apnea (OSA). However, the causal associations remain unknown. Therefore, our study used bidirectional two-sample Mendelian randomization (MR) to identify potential causal relationships between LSB/PA and OSA.MethodsWe sourced genetic variation data for LSB and PA from the UK Biobank, while data on OSA were collected from the FinnGen study. The primary analysis method employed was the inverse variance weighted (IVW) approach, complemented by the weighted median and MR-Egger methods. For sensitivity analyses, we conducted Cochran’s Q test, the MR-Egger intercept test, the MR-PRESSO global test, and the leave-one-out analysis.ResultsIVW analyses showed that genetically predicted leisure television watching (odds ratio [OR] = 1.38, 95% confidence interval [CI] = 1.09–1.75, p = 0.007) and computer use (OR = 1.48, 95% CI = 1.15–1.92, p = 0.002) significantly increased the risk of OSA. Conversely, self-reported vigorous physical activity (VPA) (OR = 0.33, 95% CI = 0.11–0.98, p = 0.046) may reduce the risk of OSA. No causal effects on OSA risk were observed for driving or self-reported moderate-to-vigorous physical activity. Furthermore, the reverse MR analysis indicated no significant causal relationship between OSA and any LSB/PA phenotype. Sensitivity tests showed no significant heterogeneity or horizontal pleiotropy.ConclusionThis study suggests that leisurely television watching and computer use are risk factors for OSA, while VPA may be a protective factor. Additionally, OSA does not affect PA or LSB levels. We recommend reducing sedentary activities, particularly television watching and computer use, and prioritizing VPA to reduce the risk of OSA. Further research in diverse populations and settings is needed to validate these findings.

When reviewing the safety of food packaging, safety assessors must determine the migration levels of a food contact substance (FCS) from the packaging into the contained food products. Migration values can be expressed relative to levels in food using a single ‘food mass-to-surface area (mF/A) ratio’, representative of the general food supply. Because no published literature has examined mF/A ratios for the current U.S. food supply, this study aimed to use food databases to develop a standard mF/A ratio representative of packaged foods in the current U.S. food supply. First, we obtained information on the food-contact surface area (A) and food mass (mF) for a selection of packaged foods sold in U.S. retail stores. To adequately represent the variation of food products on the market, we identified a representative product per food category, using a 95-category list that was derived from the USDA WWEIA Food Categories. The values for A and mF per package were determined for each representative product using product size information from the Syndigo Nutrition Database. These data were used to calculate the A/mF ratio for each of the 95 representative products, and the average A/mF ratio was determined. The average A/mF ratio was weighted using consumption data from the WWEIA component of NHANES, so that more weight was given to foods that are consumed in greater quantities. The final step was to then take the reciprocal of the averaged A/mF ratio to obtain the final mF/A ratio. The resulting mF/A ratio was 4.8 g/in2, which rounds to 5 g/in2. In summary, we determined that 5 g/in2 is representative of the current U.S. food supply and could be used as a standard mF/A ratio when estimating migration levels of an FCS from packaging into food.
For whom the wheels roll: examining the mobility of care in Washington, DC, USA

Published: June 2024

IntroductionInfrastructure regularly supports male pursuits more than women’s. Recent transportation scholarship focuses on this inequity by quantifying the daily travel of women and men for everyday care provision, often termed “the mobility of care.” Care trips include dropping off and picking up family members, accompanying young children and old adults to medical appointments, and acquiring household goods. This study analyzes gendered travel behavior in the National Capital Region of the United States, including Washington, D.C.MethodsThe basis of this study’s analysis is data from the 2017/2018 Regional Travel Survey conducted by the National Capital Region Transportation Planning Board. The survey included records from approximately 16,000 households, 2,000 in Washington, D.C. Our study sample contained 19,274 unique people who made 49,215 trips. Many of these trips were made using the local bus and subway systems. Following an established methodology, the researchers recoded trip purpose data into five broad categories: care, work, shopping, leisure, school, and all other purposes. We then ran descriptive and statistical analyses of travelers aged 18 through 65 to measure the frequencies of household demographic characteristics and person-level trips for all purposes made by five travel modes: walk, bike, car, bus, and subway.ResultsBased on our analysis, trips for work represent the majority of trips (34.7%), followed by shopping (28.2%), care (22.3%), leisure (8.5%), other (4.1%), and school trips (2.3%). Our findings indicate that women make more care-related trips during the day than men (25.1% vs. 18.8%). They also make fewer work-related trips than men (30.3% vs. 40.2%). Regression analyses revealed correlations between care-related travel by all modes and public transportation by age, race, location of residence, and income.DiscussionThe mobility of care, done mostly by women, is one of the primary reasons that people travel in and around Washington, D.C., and its suburbs. However, D.C.’s bus and subway systems are primarily designed to support the mobility of work done mostly by men. As a result, our study identifies the need for improvements in gender-responsive infrastructure, including public transportation policies and programs that explicitly address the mobility of care, improve access to care, and reduce the environmental impact of cars.

Purpose: To determine normal anatomical variation of abdominal wall musculature.Methods: A retrospective analysis of CT scans was performed on adults (&gt;18 years) with normal abdominal wall muscles. Two radiologists analysed the images independently. Distances from three fixed points in the midline were measured. The fixed points were; P1, mid-way between xiphoid and umbilicus, P2, at the umbilicus, and P3, mid-way between umbilicus and pubic symphysis. From these three fixed points the following measurements were recorded; midline to lateral innermost border of the abdominal wall musculature, midline to lateral edge of rectus abdominis muscle, and midline to medial edges of all three lateral abdominal wall muscles. To obtain aponeurotic width, rectus abdominis width was subtracted from the distance to medial edge of lateral abdominal wall muscle.Results: Fifty normal CT scan were evaluated from between March 2023 to August 2023. Mean width of external oblique aponeurosis at P1 was 16.2 mm (IQR 9.2 mm to 20.7 mm), at P2 was 23.5 mm (IQR 14 mm to 33 mm), and at P3 no external oblique muscle was visible. Mean width of the internal oblique aponeurosis at P1 was 32.1 mm (IQR 17.5 mm to 45 mm), at P2 was 10.13 (IQR 1 mm to 17.5 mm), and at P3 was 9.2 mm (IQR 3.0 mm to 13.7 mm). Mean width of the transversus abdominis aponeurosis at P1 was −25.1 mm (IQR 37.8 mm to −15.0 mm), at P2 was 29.4 mm (IQR 20 mm to 39.8 mm), and at P3 was 20.3 mm (IQR 12 mm to 29 mm).Conclusion: In this study we describe normal anatomical variation of the abdominal wall muscles. Assessing this variability on the pre-operative CT scans of ventral hernia patients allows for detailed operative planning and decision making.

Advancements in light engineering have led to the creation of pulsed laser sources capable of delivering high-repetition-rate, high-power few-cycle laser pulses across a wide spectral range, enabling exploration of many fascinating nonlinear processes occurring in all states of matter. High-harmonic generation, one such process, which converts the low-frequency photons of the driver laser field into soft x-rays, has revolutionized atomic, molecular, and optical physics, leading to progress in attosecond science and ultrafast optoelectronics. The Extreme Light Infrastructure, Attosecond Light Pulse Source (ELI ALPS) facility pioneers state-of-the-art tools for research in these areas. This paper outlines the design rationale, capabilities, and applications of plasma- and gas-based high-repetition-rate (1 kHz to 100 kHz) attosecond extreme ultraviolet (XUV) beamlines developed at ELI ALPS, highlighting their potential for advancing various research fields.

Статья посвящена проблеме построения и организации подводного акустического канала связи (ПАКС) в океанической или морской воде. При моделировании ПАКС необходимо учитывать воздействие свойств океанической или морской воды на скорость распространения и коэффициент затухания акустического сигнала в ПАКС. В работе произведены исследования влияния температуры воды, солености воды и глубины на скорость распространения акустического сигнала в океанической или морской воде. Проведен анализ влияния свойств океанической или морской воды на коэффициент затухания акустического сигнала с помощью уравнений Торпа, Фишера-Симмонса и Эйнсли-Макколма.
The article deals with the problem of constructing and organizing an underwater acoustic communication channel (UACC) in oceanic or sea water. The effect of ocean or sea water properties on the propagation rate and attenuation factor of the acoustic signal in the UACC should be taken into account when modeling the UACC. The study investigated the effect of water temperature, water salinity and depth on the speed of acoustic signal propagation in oceanic or sea water. The effect of the properties of ocean or sea water on the attenuation coefficient of the acoustic signal was analyzed using the Thorp equation, the Fisher-Simmons equation, and the Ainslie-McColm equation.

Published: June 2024

The article contains a procedure for simulating the process of formation and development of the pedagogical mastery in a primary school teacher (based on the experience of the Pavlysh secondary school). The corresponding model consists of a methodological block (it implements scientific approaches and corresponding principles – integrity, continuity and secession, individualization and differentiation, scientificity, innovation, professional and pedagogical self-improvement), a content block (reflects the content of the development of pedagogical mastery in primary school teachers, which covers three main components: love for the child (the humanistic orientation), pedagogical abilities (professional competence, pedagogical experience, pedagogical technique) and pedagogical interaction (pedagogical culture, personal qualities), an organizational and activity block (includes certain pedagogical conditions: systematic deepening of teachers' knowledge; creative development of advanced pedagogical experience, systematic self-analysis, creation of one's own methodical laboratory, harmonious atmosphere in the educational institution, free time for self-education), a diagnostic and resultative block (reflects criteria for evaluating the level of development of pedagogical mastery in primary school teachers).
It was found out that, according to V. Sukhomlynsky, the elements of pedagogical mastery of a primary school teacher are humanism, pedagogical abilities, and pedagogical interaction. Besides the professional knowledge, the knowledge of psychology (as a basis for understanding age and individual characteristics, the richness of methods of studying a child) and perfect mastery of a native language (as a basis for developing pupils' speech competence and forming a citizen) are important. Also, the important didactic skills of the primary school teacher are determined: the ability to teach to learn, to think, to work independently; to create situations of success; to predict the result of education and upbringing, its possible difficulties. Under such conditions, a teacher should be a standard for pupils, so his/her pedagogical culture and a high level of emotional intelligence development are important.
