Sport in Town: The Smart Healthy ENV Project, a Pilot Study of Physical Activity with Multiparametric Monitoring

Background: Increasing evidence links meteorological characteristics and air pollution to physiological responses during sports activities in urban areas with different traffic levels. Objective: The main objective of the Smart Healthy ENV (SHE, “Smart Monitoring Integrated System For A Healthy Urban Environment In Smart Cities”) project was to identify the specific responses of a group of volunteers during physical activity, by monitoring their heart rates and collecting breath samples, combined with data on meteorological determinants and pollution substances obtained through fixed sensor nodes placed along city routes and remotely connected to a dedicated data acquisition server. Methods: Monitoring stations were placed along two urban routes in Pisa, each two km long, with one located within the park beside the Arno river (green route) and the other in a crowded traffic zone (red route). Our sample participants were engaged in sports activities (N = 15, with different levels of ability) and were monitored through wearable sensors. They were first asked to walk back and forth (4 km) and then to run the same route. The experimental sessions were conducted over one day per route. A breath sample was also collected before each test. A questionnaire concerning temperature and fatigue perception was administered for all of the steps of the study over the two days. Results: The heart rates of the participants were monitored in the baseline condition, during walking, and while running, and were correlated with meteorological and pollutant data and with breath composition. Changes in the heart rates and breath composition were detected during the experimental sessions. These variations were related to the physical activity and to the meteorological conditions and air pollution levels. Conclusions: The SHE project can be considered a proof-of-concept study aimed at monitoring physiological and environmental variables during physical activity in urban areas, and can be used in future studies to provide useful information to those involved in sports and the broader community.
Adaptation and Measurement Invariance by Gender of the Flourishing Scale in a Colombian Sample

There is increasing interest in the study of flourishing as an indicator of subjective wellbeing. The objective herein was to adapt and study the psychometric properties of Diener’s Flourishing Scale (FS) among the Colombian population. Accordingly, a cross-sectional study was conducted with a non-probability sample of 1255 Colombian adults. The scale’s structure, invariance by gender, and convergent and concurrent validity were studied from a confirmatory perspective using structural equation models. The confirmatory factor analysis showed excellent fit indicators for the one-dimensional structure (CFI = 0.985, RMSEA = 0.039, SRMR = 0.020) as well as for the convergent (CFI = 0.909, RMSEA = 0.050, SRMR = 0.063) and concurrent (CFI = 0.966, RMSEA = 0.036, SRMR = 0.041) validity models. The correlations calculated among flourishing with positive and negative effects (PANAS), satisfaction with life (SWL), and optimism and pessimism (LOT) were statistically significant and as expected. Configural, metric, and scalar invariance across gender was confirmed. Percentiles were provided for the total score. The FS scale was a valid and reliable measure to assess high levels of wellbeing among the Colombian population.
Burnout of Healthcare Workers amid the COVID-19 Pandemic: A Japanese Cross-Sectional Survey

The coronavirus disease 2019 (COVID-19) global pandemic has drastically changed how we live and work. Amid the prolonged pandemic, burnout of the frontline healthcare professionals has become a significant concern. We conducted a cross-sectional survey study to provide data about the relationship between the COVID-19 pandemic and the prevalence of burnout in healthcare professionals in Japan. Healthcare workers in a single Japanese national university hospital participated in the survey, including basic demographics, whether a participant engaged in care of COVID-19 patients in the past 2 weeks and the Maslach Burnout Inventory. Of those, 25.4% fully answered the survey; 33.3% were doctors and 63.6% were nurses, and 36.3% engaged in care of COVID-19 patients in the past 2 weeks. Compared to those belonging to General Medicine, those in Emergency Intensive Care Unit were at higher risk of burnout (odds ratio (OR), 6.7; 95% CI, 1.1–42.1; p = 0.031). Of those who engaged in care of COVID-19 patients, 50% reported burnout while 6.1% did not (OR 8.5, 95% CI; 1.3–54.1; p = 0.014). The burnout of healthcare workers is a significant concern amid the pandemic, which needs to be addressed for sustainable healthcare delivery.
Firm Growth as a Driver of Sustainable Product Innovation: Mediation and Moderation Analysis. Evidence from Manufacturing Firms

Facing worldwide environmental and social concerns, manufacturing firms are trying to adopt effective environmentally friendly actions to mitigate their environmental impacts. Although the existent literature has provided many insights about the drivers of sustainable product innovation, little is known about the impact of firm growth. Thus, we intend to contribute to this gap in the literature by examining the impact that firm growth can have on sustainable product innovation. To achieve this goal, the partial least square (PLS) modeling technique was used to analyze a dataset of 3250 manufacturing firms from 39 different countries. The results reveal that firm growth exerts a positive effect on sustainable product innovation and that the relationship is partially mediated by the adoption of environmental practices. The findings also indicate that managerial barriers lessen the effectiveness of the adoption of environmental practices in facilitating the development of sustainable product innovation, while improving labor conditions increases it. However, operational barriers do not exert a significant moderating effect between the adoption of environmental practices and sustainable product innovation. These results prompt interesting insights related to theory development in environmental management and sustainable product innovation research.
On the real structure of gypsum crystals

X-ray diffraction patterns of gypsum exhibit different reflection intensities, depending on the conditions under which the gypsum was manufactured. Pole figures and area detector images have shown that these differences in intensity result in large part from the formation of textures during the preparation of the powder. The differences in intensity of integrated area detection images suggest that gypsum crystals can be categorized as mosaic crystals. Weissenberg photographs confirmed this claim. Calculations of lattice energy based on the theory of reciprocal crystals indicated that interpenetration twins form according to known laws through isoepitaxial overgrowth. Crystallite pairs of gypsum were known intergrown at different angles with the (010)/(010) and (010)/(010) faces. This results in six different layer arrangements. Energy was calculated by shifting one layer against another along a grid parallel to (010) and rotating it 360° around each grid point in increments of 10°. In all cases, an energetically favourable angle range was found for nearly every point on the grid.
Hand Areas Which Are Commonly Missed during Hand Disinfection by Nursing Students Who Completed a Basic Educational Course in Hand Hygiene

Abstract Background: Teaching nursing students how to correctly perform hand hygiene procedures may guarantee a reduction in transmitting pathogens through direct contact and, thus, it may lead to a decrease in the number of hospital infections. The aim of the study, which was conducted in low fidelity simulation conditions, was to assess the performance and the efficiency of a hand-rubbing disinfection technique among nursing students on the last day of their course. Materials and methods: The study was conducted in a group of 190 nursing students studying at the Jagiellonian University and it focused on the performed hand-rubbing disinfection procedure. The accuracy of the task performance was assessed by measuring the percentage of the amount of Fluo-Rub (B. Braun) fluorescent alcohol-based gel remaining on students’ hands after disinfection. The gel was rubbed into particular hand parts including four surfaces (left palm, right palm, left back and right back) divided into thirteen areas (I–XIII) and each surface was examined separately. The results were then dichotomized based on the cut-off point of 10% and two categories: “clean” and “dirty” were established. Additionally, the range of negligence in the disinfection procedure was assessed by counting the total number of the areas classified as “dirty”. The comparison of continuous and categorical variables was conducted by means of Friedman’s and Cochrane’s tests, respectively. Results: It was found out that the palm surfaces that were commonly missed during hand disinfection included the whole thumb (I and VI), the fingertip of the little finger (V) and the midpalm (XIII), whereas in the case of back surfaces (on both right and left hand) the most commonly missed areas were the fingertips and the whole thumb I–VI. Only 30 students (13%) had all 52 areas of both hands completely clean, whereas more than one third—66 students (33%)—failed to disinfect properly more than 10 areas out of all assessed ones on the surfaces of both hands. Conclusions: In the examined group of nursing students, a significant lack of compliance with hand disinfection procedures was observed and it was related mainly to thumbs and back parts of both hands. Therefore, it is essential to conduct systematic training sessions and assessment of hand hygiene procedures for nursing students at the end of every educational stage as it can lead to their developing these skills properly.
Decay of Ozone in Water: A Review

Scientific publications on ozone decay kinetics in water report very wide result variations, depending on a multiplicity of factors, such as ozone concentration, pH, temperature, alkalinity, fluid-dynamic conditions, presence of UV radiations, and concentration of organic and inorganic carbon. This paper intends to provide an engineering-oriented review that summarizes and compares the main results reported in the recent literature so that the condensed information can guide the reader in getting operational indications to assist applications and research.
A Cross-Country Examination on the Fear of COVID-19 and the Sense of Loneliness during the First Wave of COVID-19 Outbreak

The aim of the current study is to examine gender, age. and cross-country differences in fear of COVID-19 and sense of loneliness during the lockdown, by comparing people from those countries with a high rate of infections and deaths (e.g., Spain and Italy) and from countries with a mild spread of infection (e.g., Croatia, Serbia, Slovakia, Slovenia, and Bosnia and Herzegovina). A total of 3876 participants (63% female) completed an online survey on “Everyday life practices in COVID-19 time” in April 2020, including measures of fear of COVID-19 and loneliness. Males and females of all age groups in countries suffering from the powerful impact of the COVID-19 pandemic reported greater fear of COVID-19 and sense of loneliness. In less endangered countries, females and the elderly reported more symptoms than males and the young; in Spanish and Italian samples, the pattern of differences is considerably more complex. Future research should thoroughly examine different age and gender groups. The analysis of emotional well-being in groups at risk of mental health issues may help to lessen the long term social and economic costs due to the COVID-19 outbreak.
Trust and Compliance with COVID-19 Preventive Behaviors during the Pandemic

This study examined the role of trust in lay people’s health behaviors related to the current pandemic. A total of 376 Israelis completed an online questionnaire during the second lockdown. A latent profile analysis was conducted to identify profiles of individuals based on their levels of trust in the various institutions and stakeholders examined in this study. A three-profile solution was deemed most appropriate. The largest profile (N = 178) was characterized by low levels of trust in the government, but high levels of trust in science and one’s primary care provider. Next, was the generally low trust profile (N = 108), characterized by low levels of trust directed towards all stakeholders and institutes. The third profile (N = 79) was characterized by high levels of trust. Results are discussed in relation to the important role of trust in determining people’s response to the current pandemic and the unique features of Israeli society.
Quality of Work Life and Contribution to Productivity: Assessing the Moderator Effects of Burnout Syndrome

This study is focused on assessing the effects of burnout as a moderator of the relationship between employees’ quality of work life (QWL) and their perceptions of their contribution to the organization’s productivity by integrating the QWL factors into the trichotomy of (de)motivators of productivity in the workplace. The empirical findings resulting from an OLS multiple regression, with interaction terms, applied to a survey administered at 514 employees in 6 European countries, point out two important insights: (i) QWL hygiene factors (e.g., safe work environment and occupational healthcare) positively and significantly influence the contribution to productivity; and (ii) burnout de-motivator factors (that is, low effectiveness, cynicism, and emotional exhaustion) significantly moderate the relationship between QWL and the contribution to productivity. Combining burnout with other QWL components, such as occupational health, safe work, and appropriate salary, new insights are provided concerning the restricting (i.e., low effectiveness and cynicism) and catalyzing (emotional exhaustion) burnout components of contribution to productivity. These findings are particularly relevant given the increased weight of burnout, mental disorders and absenteeism in the labor market, affecting individuals’ quality of life and organizations’ performance and costs.
Old Tricks, New Opportunities: How Companies Violate the International Code of Marketing of Breast-Milk Substitutes and Undermine Maternal and Child Health during the COVID-19 Pandemic

Breastfeeding is critical to maternal and child health and survival, and the benefits persist until later in life. Inappropriate marketing of breastmilk substitutes (BMS), feeding bottles, and teats threatens the enabling environment of breastfeeding, and exacerbates child mortality, morbidity, and malnutrition, especially in the context of COVID-19. These tactics also violate the International Code of Marketing of Breast-Milk Substitutes. This study identified marketing tactics of BMS companies since the start of the COVID-19 pandemic by reviewing promotional materials and activities from 9 companies in 14 countries, and the official Code reporting data from the Philippines. Eight qualitative themes emerged that indicate companies are capitalizing on fear related to COVID-19 by using health claims and misinformation about breastfeeding. Other promotional tactics such as donations and services were used to harness the public sentiment of hope and solidarity. Past studies show that these tactics are not new, but the pandemic has provided a new entry point, helped along by the unprecedented boom in digital marketing. There was a sharp increase of reported violations in the Philippines since the pandemic: 291 during the first months of the outbreak compared with 70 in all of 2019, corroborating the thematic findings. A lack of public awareness about the harm of donations and inadequate Code implementation and enforcement have exacerbated these problems. Proposed immediate action includes using monitoring findings to inform World Health Assembly (WHA) actions, targeted enforcement, and addressing misinformation about breastfeeding in the context of COVID-19. Longer-term action includes holding social media platforms accountable, raising public awareness on the Code, and mobilizing community monitoring.
Technical Accuracy of Dental Laboratories in the Quality and Shade Matching of Porcelain Fused to Metal Crowns: An In Vitro Study

Dental laboratories (LABs) are integral to the performance of a dentist in providing successful oral rehabilitation. The aim of this study was to compare the adaptation, contour, contacts, and shade matching of different government and commercial dental LABs in the fabrication of porcelain fused to metal (PFM) crowns. Thirty-two dental LABs were selected to fabricate PFM crowns (one PFM crown each). Marginal adaptation, contour, proximal contacts, and shade matching were evaluated. Evaluation of the crowns’ quality was performed following modified USPHS/FDI criteria. Visual and colorimeter assessments were employed to evaluate shade matching. Differences between groups were examined by Pearson’s Chi-square and Fisher’s exact test. The quality of marginal adaptation of crowns was good in 81.25%, however the quality of contours, contacts, and shade matching was compromised in 43.75%, 59.38%, and 39% of all LABs, respectively. Visual and colorimeter shade matching was acceptable in 62.5% and 80% of LABs in the cervical third and middle third regions of crowns, respectively, however in the incisal third the shade matching was unacceptable in nearly 60% of LABs. Commercial laboratories showed significantly better contours and shade matching, but not marginal adaptation. However, no significant differences were found in comparison of proximal contacts between the groups.
Impact of COVID-19 Restrictions on Western Australian Children’s Physical Activity and Screen Time

Physical activity is essential for children’s healthy development, yet COVID-19 physical distancing restrictions such as school closures and staying at home, playground closures, and the cancelling of organised community sport have dramatically altered children’s opportunities to be physically active. This study describes changes in levels of physical activity and screen time from February 2020 (i.e., before COVID-19 restrictions were introduced in Western Australia) to May 2020 (i.e., when COVID-19 restrictions were in place). Parents of children aged 5 to 9 years from Western Australia were eligible to participate and recruited through convenience sampling. An online survey instrument that included validated measures of their children’s physical activity (unstructured, organized, home-based, indoor/outdoor active play, dog play/walking), sociodemographic, and other potential confounders was administered to parents. Paired t-tests and mixed ANOVA models assessed changes in physical activity outcomes. The analytic sample comprised parents of 157 children who were 6.9 years of age (SD = 1.7) on average. Overall, weekly minutes of total physical activity (PA) did not change from before to during COVID-19. However, frequency and duration (total and home-based) of unstructured physical activity significantly increased. Outdoor play in the yard or street around the house, outdoor play in the park or playground or outdoor recreation area, and active indoor play at home all significantly increased. Frequency and total duration of organised physical activity significantly declined during COVID-19 distancing. During Western Australian COVID-19 restrictions, there was an increase in young children’s unstructured physical activity and outdoor play and a decrease in organised physical activity. It remains to be seen whether children’s increased physical activity has been sustained with the easing of physical distancing restrictions.
Preclinical Evaluation of 99mTc-ZHER2:41071, a Second-Generation Affibody-Based HER2-Visualizing Imaging Probe with a Low Renal Uptake

Radionuclide imaging of HER2 expression in tumours may enable stratification of patients with breast, ovarian, and gastroesophageal cancers for HER2-targeting therapies. A first-generation HER2-binding affibody molecule [99mTc]Tc-ZHER2:V2 demonstrated favorable imaging properties in preclinical studies. Thereafter, the affibody scaffold has been extensively modified, which increased its melting point, improved storage stability, and increased hydrophilicity of the surface. In this study, a second-generation affibody molecule (designated ZHER2:41071) with a new improved scaffold has been prepared and characterized. HER2-binding, biodistribution, and tumour-targeting properties of [99mTc]Tc-labelled ZHER2:41071 were investigated. These properties were compared with properties of the first-generation affibody molecules, [99mTc]Tc-ZHER2:V2 and [99mTc]Tc-ZHER2:2395. [99mTc]Tc-ZHER2:41071 bound specifically to HER2 expressing cells with an affinity of 58 ± 2 pM. The renal uptake for [99mTc]Tc-ZHER2:41071 and [99mTc]Tc-ZHER2:V2 was 25–30 fold lower when compared with [99mTc]Tc-ZHER2:2395. The uptake in tumour and kidney for [99mTc]Tc-ZHER2:41071 and [99mTc]Tc-ZHER2:V2 in SKOV-3 xenografts was similar. In conclusion, an extensive re-engineering of the scaffold did not compromise imaging properties of the affibody molecule labelled with 99mTc using a GGGC chelator. The new probe, [99mTc]Tc-ZHER2:41071 provided the best tumour-to-blood ratio compared to HER2-imaging probes for single photon emission computed tomography (SPECT) described in the literature so far. [99mTc]Tc-ZHER2:41071 is a promising candidate for further clinical translation studies.
The Effects of Abdominal Hypopressive Training on Postural Control and Deep Trunk Muscle Activation: A Randomized Controlled Trial

Background: Abdominal Hypopressive Training (AHT) provides postural improvement, and enhances deep trunk muscle activation. However, until recently, there was a lack of scientific literature supporting these statements. The major purpose of this study was to investigate the effect of AHT on posture control and deep trunk muscle function. Methods: 125 female participants aged 18–60 were randomly allocated to the Experimental Group (EG), consisting of two sessions of 30 min per week for 8 weeks of AHT, or the Control Group (CG), who did not receive any treatment. Postural control was measured with a stabilometric platform to assess the static balance and the activation of deep trunk muscles (specifically the Transverse Abdominal muscle (TrA)), which was measured by real-time ultrasound imaging. Results: The groups were homogeneous at baseline. Statistical differences were identified between both groups after intervention in the Surface of the Center of Pressure (CoP) Open-Eyes (S-OE) (p = 0.001, Cohen’s d = 0.60) and the Velocity of CoP under both conditions; Open-Eyes (V-OE) (p = 0.001, Cohen´s d = 0.63) and Close-Eyes (V-CE) (p = 0.016, Cohen´s d = 0.016), with the EG achieving substantial improvements. Likewise, there were statistically significant differences between measurements over time for the EG on S-OE (p < 0.001, Cohen´s d = 0.99); V-OE (p = 0.038, Cohen´s d = 0.27); V-CE (p = 0.006, Cohen´s d = 0.39), anteroposterior movements of CoP with Open-Eyes (RMSY-OE) (p = 0.038, Cohen´s d = 0.60) and activity of TrA under contraction conditions (p < 0.001, Cohen´s d = 0.53). Conclusions: The application of eight weeks of AHT leads to positive outcomes in posture control, as well as an improvement in the deep trunk muscle contraction in the female population.
