Published: October 2022

Organic products have grown ever more popular in recent years due to increased concerns regarding one’s health, the environment, and sustainability. The COVID-19 pandemic has only accelerated this growth, prompting producers to adapt to a rapidly growing market while maintaining the same standard of quality. We have conducted a questionnaire-based pilot study on 190 organic food consumers from Bihor county, Romania, in order to analyze the main factors influencing customers’ beliefs regarding organic food consumption, as well as assess the extent to which their consumption frequency changed after the pandemic. A principal component analysis was performed, dividing the factors into two categories referring to intrinsic and extrinsic characteristics of the products, respectively. It was noticed that the most important cues were ranked the same by our 190 respondents, regardless of their socio-demographical background. At the same time, people who consumed organic products more frequently before the pandemic have either maintained or increased their consumption, while more indifferent consumers maintained or decreased the proportion of organic foods in their diet.
Using Mindfulness to Improve Mental Health Outcomes of Immigrant Women with Experiences of Intimate Partner Violence
Authors: Vroegindewey Ashley , Sabri Bushra
Published: October 2022

Immigrant women are disproportionately affected by intimate partner violence (IPV), which poses risk for mental health problems, such as PTSD and depression. Post-migration barriers limit immigrant women’s access to supportive services, which can further debilitate their mental health symptoms and their safety. The Being safe, Healthy, and Positively Empowered (BSHAPE) digital intervention was designed to address physical safety and healthcare needs of immigrant women through a multi-component approach that integrated mindfulness-based stress reduction (MBSR) practices. This paper reports qualitative feedback findings from eighteen Black immigrant women with recent IPV exposure and co-occurring mental health symptoms, who participated in the mindfulness sessions of BSHAPE. We identified elements of mindfulness that women perceived as beneficial in their healing. Women’s feedback indicated healing and empowerment through positive appraisals and coping strategies. The benefits were noted for mindfulness elements promoting self-compassion, self-actualization, intentionality of moving forward in life, and developing positivity or a sense of optimism. Other helpful elements were relaxation, self-care and reflection, self-awareness, self-control and focused thinking. Our findings show that incorporating mindfulness practices in interventions can be beneficial for promoting the healing and empowerment of immigrant women in abusive relationships.

Published: October 2022

Background: Transcranial direct current stimulation (tDCS) has emerged as a prevention method or minimizer of the normal cognitive deterioration that occurs during the aging process. tDCS can be used to enhance cognitive functions such as immediate memory, learning, or working memory in healthy subjects. The objective of this study was to analyze the effect of two 20-min sessions of anodal transcranial direct stimulation on immediate memory, learning potential, and working memory in healthy older adults. Methods: A randomized, single-blind, repeated-measures, sham-controlled design was used. The sample is made up of 31 healthy older adults, of whom 16 were in the stimulation group and 15 were in the sham group. The anode was placed on position F7, coinciding with the left dorsolateral prefrontal cortex region, and the cathode was placed on Fp2, the right supraorbital area (rSO). Results: When comparing the results of the treatment group and the sham group, differences were observed in working memory and learning potential; however, no differences in immediate memory were found. Conclusion: The results showed that tDCS is a non-invasive and safe tool to enhance cognitive processes in healthy older adults interested in maintaining some cognitive function.

Published: October 2022

Heart rate time series are widely used to characterize physiological states and athletic performance. Among the main indicators of metabolic and physiological states, the detection of metabolic thresholds is an important tool in establishing training protocols in both sport and clinical fields. This paper reviews the most common methods, applied to heart rate (HR) time series, aiming to detect metabolic thresholds. These methodologies have been largely used to assess energy metabolism and to identify the appropriate intensity of physical exercise which can reduce body weight and improve physical fitness. Specifically, we focused on the main nonlinear signal evaluation methods using HR to identify metabolic thresholds with the purpose of identifying a method which can represent a useful tool for the real-time settings of wearable devices in sport activities. While the advantages and disadvantages of each method, and the possible applications, are presented, this review confirms that the nonlinear analysis of HR time series represents a solid, robust and noninvasive approach to assess metabolic thresholds.

Introduction: Safety of the environment in which vegetables are grown, marketed and consumed is paramount as most are eaten raw. Irrigation sources include open drains and streams, which are often contaminated with human and animal waste due to poor sanitation infrastructure. In irrigated vegetable farms using such sources in Ghana, we assessed Escherichia coli counts, antibiotic resistance patterns and resistant genes on irrigated lettuce. Methods: A cross-sectional study was conducted between January–May 2022, involving five major vegetable farms in Ghana. Results: Escherichia coli was found in all 25 composite lettuce samples analyzed. Counts expressed in CFU/g ranged from 186 to 3000, with the highest counts found in lettuce irrigated from open drains (1670) and tap water using hose pipes (3000). Among all bacterial isolates, resistance ranged between 49% and 70% for the Watch group of antibiotics, 59% for the Reserved group and 82% were multidrug-resistant. Of 125 isolates, 60 (48%) were extended-spectrum beta-lactamase-producing, of which five (8%) had the blaTEM-resistant gene. Conclusions: Lettuce was contaminated with Escherichia coli with high levels of antibiotic resistance. We call on the Ghana Ministry of Food and Agriculture, Food and Drugs Authority and other stakeholders to support farmers to implement measures for improving vegetable safety.

Authors: Liu Diyi , Cheng Kun , Huang Kevin , Ding Hui , Xu Tiantong , Chen Zhenni , Sun Yanqi
Published: October 2022

Bibliometric techniques and social network analysis are employed in this study to evaluate 14,955 papers on air pollution and health that were published from 2001 to 2021. To track the research hotspots, the principle of machine learning is applied in this study to divide 10,212 records of keywords into 96 clusters through OmniViz software. Our findings highlight strong research interests and the practical need to control air pollution to improve human health, as evidenced by an annual growth rate of over 15.8% in the related publications. The cluster analysis showed that clusters C22 (exposure, model, mortality) and C8 (health, environment, risk) are the most popular topics in this field of research. Furthermore, we develop co-occurrence networks based on the cluster analysis results in which a more specific keyword classification was obtained. These key areas include: “Air pollutant source”, “Exposure-Response relationship”, “Public & Occupational Health”, and so on. Future research hotspots are analyzed through characteristics of the cluster groups, including the advancement of health risk assessment techniques, an interdisciplinary approach to quantifying human exposure to air pollution, and strategies in health risk assessment.
Influences of Boundary-Spanning Leadership on Job Performance: A Moderated Mediating Role of Job Crafting and Positive Psychological Capital
Authors: Xue Rukuan , Woo Hyung Rok
Published: October 2022

Due to the pursuit of a flexible organization, the interest in internal as well as external boundary management has increased as a key to achieve high performance. This study identified boundary-spanning leadership (BSL) as a critical factor enhancing job crafting and job performance of subordinates. By examining the mediating effect of job crafting and the moderating effect of positive psychological capital (PsyCap), the authors aimed to present the effects of BSL assimilating job resources, such as external information and knowledge into organization. Data were collected from 238 workers of 11 companies using questionnaires in South Korea to test the moderated mediation model. The results of regression analysis using LISREL and SPSS, revealed that the manager’s BSL provoked job crafting, which in turn achieved job performance of subordinates. Moreover, PsyCap positively moderated the effect of BSL on job crafting of subordinates. The findings suggested, therefore, in order to maximize the positive effects of BSL in an organization, it should also be necessary to understand and boost PsyCap along with enhancing job crafting.

Published: October 2022

The present study illustrates zooplankton dynamics in relation to environmental factors from the surrounding area of Tiaowei Island based on ten seasonal sampling cruises over three years. A total of 116 species of zooplankton were collected with a predominance of Copepoda (mainly consisting of Centropagidae, Oithonidae, Acartia, Labidocera and Paracalanus), accounting for 31.6 % of the total number of species. The diversity indices indicated a relatively high richness, abundance and evenness of zooplankton ranging from 2.794 to 4.012 on the Shannon–Wiener index for each cruise. More than 20 species of Cnidaria medusae are found as gelatinous organisms, which not only compete with fish but also potentially cause disasters. Significant seasonal variations were detected in both the zooplankton structure and environmental variables. NMDS illustrated a highly overlapping community structure in spring, autumn and winter, while the zooplankton composition in the summer was different from that of the other three seasons with a higher diversity index. Meanwhile, out of thirteen environmental parameters, eight varied significantly among seasons but there were no significant variations among stations. The biota–environmental relationship following a redundancy analysis revealed that water temperature, pH, salinity, dissolved oxygen and suspended particulate composition were the main environmental parameters, seasonally impacting the zooplankton communities. Planktonic larvae (such as nauplius larvae and branchyura zoea) and some zooplankton (including Corophium sinensis and Oithonasimilis) were significantly vulnerable to the dynamics of suspended particulate composition and water temperature.
Does Participating in Physical Exercise Make Chinese Residents Happier?—Empirical Research Based on 2018 Chinese General Social Survey
Authors: Gan Liluo , Jiang Yumei
Published: October 2022

Participating in physical exercise to improve fitness, as well as experience the social and economic functions of sport, can help individuals improve their subjective well-being. The ordinary least squares (OLS) regression model was used to empirically study the impact of the frequency and intensity of physical exercise on Chinese residents’ subjective well-being and its mechanisms using data from the 2018 China General Social Survey (CGSS). The findings revealed that participating in physical exercise significantly increased Chinese residents’ subjective well-being; the impact of physical exercise on Chinese residents’ subjective well-being varied with age, marriage, political status, and so on, and participation in physical exercise improved in rural individuals, male individuals, and individuals from the eastern regions. Higher intensity physical exercise increases the likelihood of subjective well-being; urban individuals, female individuals, and individuals in the central and eastern regions have a higher probability of improving subjective well-being.

Authors: Mertens Michel GCAM , Meeus Mira , Pieters Louise , Balasch-Bernat Mercè , Dueñas Lirios , Verborgt Olivier , Struyf Filip
Published: October 2022

The coracoid pain test (CPT) could contribute to the diagnosis of frozen shoulder (FS) with palpation. However, due to assessor performance these values might be unreliable. Therefore, the aim was to explore the diagnostic accuracy of an instrument-assisted CPT and two alternative approaches (pain severity and side comparison) for assistance in the diagnosis of FS. Patients with FS and healthy age-matched controls were recruited. All participants underwent the instrument-assisted CPT on both shoulders with a pressure algometer. Sensitivity, specificity, and likelihood ratios were determined for the three approaches. In total, 35 patients with FS and 35 healthy participants were included. The original approach was positive in eight participants (11.4%), with only sufficient specificity to draw a conclusion. The pain severity approach was positive in 31 participants (44.3%) with sufficient sensitivity, specificity and likelihood ratios. The side comparison approach was positive in 10 participants (14.3%) with excellent specificity and positive likelihood ratio. The specificity of the instrument-assisted CPT can be used to increase the probability of FS with both the original and alternative approaches. Only the pain severity approach can draw a conclusion with a negative test result. This study should be repeated with a cross-sectional design to strengthen and confirm the conclusions.

Published: October 2022

Effective patient–provider communication improves mammography utilization. Using information technology (IT) promotes health outcomes. However, there are disparities in access to IT that could contribute to disparities in mammography utilization. This study aims to assess the association between IT-based health care communication and mammography utilization and to evaluate if this effect is modified by race/ethnicity and age. To this end, this study was conducted using the National Health Interview Survey from 2011 to 2018. A total of 94,290 women aged 40 years and older were included. Multiple logistic regression models were used, and odds ratios were reported. The study found that all IT-based healthcare communication strategies were significantly associated with mammography utilization in all years from 2011 to 2018. In 2018, women who looked up health information on the internet, scheduled a medical appointment on the internet, and communicated with providers by email had a significantly higher chance to use mammography (p ≤ 0.005 for all strategies across all years). White women and women aged 50 years and older benefited the most from IT-based healthcare communication. In conclusion, facilitating access to IT may help increase mammography utilization, which may contribute to eliminating disparities in breast cancer mortality.
An Analysis of Theoretical Perspectives in Research on Nature-Based Interventions and Pain
Authors: Jones Reo J. F. , Littzen Chloé O. R.
Published: October 2022

Chronic pain results from a complex series of biomechanical, inflammatory, neurological, psychological, social, and environmental mechanisms. Pain and pain-related diseases are the leading causes of disability and disease burden globally. Employing nature-based interventions for the treatment of pain is an emerging field. Current theory driving the suggested mechanism(s) linking the pain reducing effects of nature-based interventions is lacking. A two-step approach was taken to complete a theoretical review and analysis. First, a literature review was completed to gather a substantive amount of research related to theoretical frameworks on the topic of nature-based interventions and pain. Secondly, a theoretical analysis as proposed by Walker and Avant was completed to explore current theoretical frameworks accepted in the literature on nature-based interventions and pain. Stress reduction theory and attention restoration theory were the most common theoretical frameworks identified. Neither theoretical framework explicitly identifies, describes, or intends to adequately measure the concept of pain, revealing a limitation for their application in research with nature-based interventions and pain. Theoretical development is needed, as it pertains to nature-based interventions and pain. Without this development, research on nature-based interventions and pain will continue to use proxy concepts for measurement and may result in misrepresented findings.

Authors: Socan Maja , Erčulj Vanja Ida
Published: October 2022

The aim of the study was to investigate the real-life experience of persons infected with SARS-CoV-2 in Slovenia in the first pandemic wave and how the buffering effect of social and informational support affected negative feelings. We used a self-administrated questionnaire. There were 1182 eligible notified cases with the response rate 64.9%. At least 62% of responders were able to follow the isolation rules, while 21.1% did not or could not organize their living separately from other household members. The main providers during the isolation period were close family members. The most prevalent emotion in our study was worry (70.3%) and fear (37.6%). Worry and fear during the illness were less probable for men than women, but more probable for older patients. Participants with strong emotional support had lower odds of being sad. Those who were exposed to a larger number of sources of information had higher odds of being worried. Those patients who used a higher number of more credible sources of information had higher odds of being afraid during illness. Pets did not play a special role in psychological well-being. The role of the media and public health communications should be explored further to achieve an improved response.

Authors: Wdowiak-Szymanik Aleksandra , Wdowiak Agata , Szymanik Piotr , Grocholewicz Katarzyna
Published: October 2022

Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2. The pandemic over the past two years has completely changed people’s daily habits with an impact on oral hygiene, eating habits, and oral health. Materials and methods: The available literature was reviewed on the PubMed platform and from other sources MEDLINE and Cochrane Reviews. The analysis included comparative and clinical trials as well as pragmatic clinical/randomized controlled trials, and observational studies which focused on the effects of COVID-19 on the dietary habits of the population, oral hygiene, and caries incidence. Results: The analysis shows that the COVID-19 pandemic had a significant negative impact on dietary habits and an ambiguous impact on oral health habits of the population. The researchers showed that patients’ visits were limited only to those necessary, because of fear of infecting with the SARS-CoV-2. Conclusions: The literature review shows that the COVID-19 pandemic, by affecting many aspects of everyday life, including eating habits, caring for oral hygiene, and avoiding regular visits to the dentist, may generate an increase in oral diseases. Due to the differences in knowledge results, further research observations in this field are necessary.
Qualitative Purpose Profiles of Chinese Student Teachers
Authors: Jiang Fei , Reilly Timothy S. , Mariano Jenni Menon
Published: October 2022

Teachers are well positioned to help students cultivate their purpose in life, which is an asset that is associated with optimal development. Teachers must also have a grasp on their own sense of purpose, especially during times of intense social pressure and change, when the capability to sustain and support worthy aims may impart personal resilience and contribute to the social good. To train educators who have this capability, it is therefore vital for teacher education programs to in turn understand their own students’ individualized purpose statuses. Using a qualitative person-centered approach, the current study identified purpose profiles of teacher education candidates in China as part of a larger multinational study. Three hundred and thirty-one participants wrote answers to questions about the content and fulfillment of their purpose in life, and statements were reliably coded for how specifically the respondents referenced their purpose, and for whether their purpose aimed to benefit others. A consensual qualitative research approach then identified four purpose profiles: beyond-the-self purpose, self-oriented life goal, daydreamer and purposeless. The meaning of these profiles and their significance for cultivating purpose among China’s teachers are discussed.

Authors: Muñoz-Paredes Inés , Herrero Azael J. , Llamas-Ramos Rocío , Rodríguez-Pérez Vicente , Seco-Calvo Jesús
Published: October 2022

Background: The relationship between fragility and neurological diseases is extensive and affects many patients with multiple sclerosis (MS), whose risk factors are related to fragility. Objective: To study the effects of exercise and transcranial direct current stimulation (tDCS) in MS patients with fatigue from four dimensions: functional mobility, balance, fatigue, and depression. Methods: A total of 12 patients who belonged to two associations of people with physical disabilities participated. Functional mobility, depression, balance, and fatigue were assessed before and after the intervention. Transcranial direct current stimulation and the exercise program were carried out over a 4-week period with a wash-out period of 5 months. Results: After the application of tDCS, we found significant improvements in balance (p < 0.05, g = 0.632), depression (p < 0.05, g = 0.402), functional mobility (p < 0.05, g = 0.297), and fatigue (p < 0.05, g = 0.526). After the exercise program, significant improvements were shown in balance (p < 0.01, g = 0.418), depression (p < 0.001, g = 0.540), functional mobility (p < 0.01, g = 0.262), and fatigue (p < 0.01, g = 0.742). Two-way mixed-measures ANOVA showed that all variables improved in both groups, with significant differences over time but not between groups. Secondary analysis showed significant correlations between balance and functional mobility (r = 0.671, p = 0.017), depression and fatigue (r = 0.586, p = 0.044) and between intensity of rehabilitation and balance (r = 0.622, p = 0.031). CONCLUSION: Participating in an exercise program and receiving tDCS separately improved the variables of depression, balance, mobility, and fatigue.

Published: October 2022

The COVID-19 pandemic has burdened the healthcare system and influenced individuals’ health-related choices. The aim of the study was to estimate the prevalence and to identify the correlates of the use of more and less effective contraceptive methods among Poles in the initial period of the COVID-19 pandemic. The cross-sectional online study was conducted among the representative sample of 642 female respondents aged 18–49. Three groups of contraception choices (only effective methods—42.2%, mixed effective and ineffective methods—26.8%, none—31.0%) were distinguished and 11 potential determinants were considered. One in ten women declared having difficulty in accessing contraception during the first months of the pandemic. A multinomial logistic regression model explained 48.7% of the variation in contraceptive method choice. Both effective and ineffective methods were more often declared by young women, and less often in case of lower education, planning children or subjective no need for contraception. In addition, factors that reduced the chance of effective contraception were poor financial situation, already having children and a relatively higher degree of religiosity. The study confirmed that a significant share of Polish women do not opt for effective methods of contraception. Their choices had strong demographic, social and cultural determinants.
University Students Eating Habits: Normal Semester vs. Lockdown Period Caused by COVID-19 Pandemic
Authors: Monteiro Mónica , Ferreira-Pêgo Cíntia
Published: October 2022

In the face of the COVID-19 pandemic, university students’ eating habits may change due to the stress caused by mandatory full lockdown and social isolation, as well as uncertainty about their academic future. An analysis of 332 Portuguese university students from different areas of study was carried out through an online questionnaire to verify if the lockdown period caused by COVID-19 had any influence on the students’ eating habits, as well as if this differed among students from health sciences courses and those from other areas. We found that, compared to a normal semester of classes, during the lockdown period, healthier eating habits were adopted, characterized by a decrease in meal delivery platforms used, self-reported consumption of fast-food, pre-cooked meals, foods rich in sugar and salt, and sugar-sweetened and alcoholic beverages, as well as increased self-reported consumption of vegetables, fruit and legumes, and physical exercise. Thus, although the lockdown led to stress and uncertainty, university students were able to take care of their eating habits and lifestyle, probably as a way of feeling stronger and safer against this disease.
Urban Agriculture as a Means to Food Sovereignty? A Case Study of Baltimore City Residents
Authors: Colson-Fearon Brionna , Versey H. Shellae
Published: October 2022

A large body of research suggests that neighborhood disparities in food access persist. Emerging evidence suggests that the global COVID-19 pandemic likely exacerbated disparities in food access. Given the potential role that alternative food networks (AFNs) and local food sources may play during times of extreme scarcity, this study examines urban agriculture (e.g., community farms and gardens) as a sustainable strategy to address food insecurity. In-depth qualitative interviews with fifteen community stakeholders revealed several major themes including food insecurity as a feature of systemic racism, food affordability and distance to food as major barriers to food security, and the role of AFNs in creating community empowerment. Our findings indicate that urban agricultural practices help build social capital, inform and educate community members about healthy eating behaviors, and facilitate the distribution of affordable food. Implications for future research and policy targeting sustainable food distribution in marginalized communities of color are discussed.
Analysis of the Spatial Association Network of PM2.5 and Its Influencing Factors in China
Authors: Wang Huiping , Ge Qi
Published: October 2022

The spatial association network of PM2.5 is constructed using a modified gravity model, with the data of 31 provinces in China from 2009–2020. On this basis, the spatial correlation structure of PM2.5 and its influencing factors were investigated through social network analysis (SNA). The results showed that, first, the PM2.5 has a typical and complex spatial correlation, and the correlation degree tends to decrease with the implementation of collaborative management. Second, they show that there is a clear “core-edge” distribution pattern in the network. Some areas with serious PM2.5 pollution have experienced different degrees of decline in centrality due to policy pressure. Third, the network is divided into “net benefits”, “net spillovers”, “two-way spillovers” and “brokers”. The linkage effect among the four blocks is obvious. Fourth, the government intervention and the industrial structure differentiation promote the formation of the network, but environmental regulation and car ownership differentiation have the opposite effect on the network.
Study on the Impact of Government Health Expenditure Equity on Residents’ Health Level in the Chengdu–Chongqing Economic Circle of China
Authors: Yu Haidong , Peng Yujie , Pu Lanfang
Published: October 2022

Background: When the global COVID-19 epidemic continues to spread, residents pay more attention to their health. This paper studies the relationship between the equity of government health expenditure and the health level of residents. Methods: The Theil index and a principal component analysis were used to measure the equity of government health expenditure and the health level of residents in the Chengdu–Chongqing economic circle. Then, an empirical study on the relationship between the equity of government health expenditure and the health level of residents in this region was conducted with the System GMM model. Results: 1. The Theil index rose from 0.0115 in 2015 to 0.0231 in 2017 and gradually decreased to 0.0106 in 2020. 2. The overall health level of residents showed an upward trend, rising from 1.95 in 2015 to 2.33 in 2017, then remained high and fluctuated slightly. 3. There was a positive correlation between the Theil index and the health level of residents at a significance level of 1% (β = 0.903, p < 0.01). Conclusions: 1. The Theil index was close to 0, indicating that the equity of government health expenditure in the Chengdu–Chongqing economic circle was generally good. 2. The health level of residents in the Chengdu–Chongqing economic circle had improved compared to before. 3. The fairer the government’s health expenditure, the higher the residents’ health level.
State Trends of Cannabis Liberalization as a Causal Driver of Increasing Testicular Cancer Rates across the USA
Authors: Reece Albert , Hulse Gary
Published: October 2022

Background. The cause of the worldwide doubling-tripling of testicular cancer rates (TCRs) in recent decades is unknown. Previous cohort studies associated cannabis use with TCR including dose–response relationships but the contribution of cannabis to TCRs at the population level is unknown. This relationship was tested by analyzing annual trends across US states and formally assessed causality. Four US datasets were linked at state level: age-adjusted TCRs from Centers for Disease Control Surveillance Epidemiology and End Results database; drug use data from annual National Survey of Drug Use and Health including 74.1% response rate; ethnicity and median household income data from the US Census Bureau; and cannabinoid concentration data from Drug Enforcement Agency reports. Data was processed in R in spatiotemporal and causal inference protocols. Results. Cannabis-use quintile scatterplot-time and boxplots closely paralleled those for TCRs. The highest cannabis-use quintile had a higher TCR than others (3.44 ± 0.05 vs. 2.91 ± 0.2, mean ± S.E.M., t = 10.68, p = 1.29 × 10−22). A dose–response relationship was seen between TCR and Δ9-tetrahydrocannabinol (THC), cannabinol, cannabigerol, and cannabichromene (6.75 × 10−9 < p < 1.83 × 10−142). In a multivariate inverse probability-weighted interactive regression including race and ethnic cannabis exposure (ECE), ECE was significantly related to TCR (β-estimate = 0.89 (95%C.I. 0.36, 2.67), p < 2.2 × 10−16). In an additive geospatiotemporal model controlling for other drugs, cannabis alone was significant (β-estimate = 0.19 (0.10, 0.28), p = 3.4 × 10−5). In a full geospatial model including drugs, income and ethnicity cannabinoid exposure was significant (cannabigerol: β-estimate = 1.39 (0.024, 2.53), p = 0.0017); a pattern repeated at two spatial and two temporal lags (cannabigerol: β-estimate = 0.71 (0.05, 1.37), p = 0.0.0350; THC: β-estimate = 23.60 (11.92, 35.29), p = 7.5 × 10–5). 40/41 e-Values > 1.25 ranged up to 1.4 × 1063 and 10 > 1000 fitting causal relationship criteria. Cannabis liberalization was associated with higher TCRs (ChiSqu. = 312.2, p = 2.64 × 10−11). Rates of TC in cannabis-legal states were elevated (3.36 ± 0.09 vs. 3.01 ± 0.03, t = 4.69, p = 4.86 × 10−5). Conclusions. Cannabis use is closely and causally associated with TCRs across both time and space and higher in States with liberal cannabis legislation. Strong dose–response effects were demonstrated for THC, cannabigerol, cannabinol, cannabichromene and cannabidiol. Cannabinoid genotoxicity replicates all major steps to testicular carcinogenesis including whole-genome doubling, chromosomal arm excision, generalized DNA demethylation and chromosomal translocations thereby accelerating the pathway to testicular carcinogenesis by several decades.

Published: October 2022

This study aimed to understand the knowledge of Portuguese citizens about air quality and the extent to which the concerns about specific environmental problems can motivate their acquaintance of information. Moreover, this study also allowed to understand which information about air quality needs further dissemination to provide the citizens with all the available tools and the correct knowledge. For this, a national online survey about air quality perception was conducted, where 1131 answers were obtained and two different populations were compared: the general population and a sub-population from an urban-industrial area of Lisbon metropolitan area that had experienced frequent air pollution events in the past. Air pollution was considered the environmental topic of higher concern among this sub-population (61.4%), while in the general population it ranked thirdly (27.4%). Generally, the sub-population showed higher knowledge about air quality than the general population, with 61% being able to identify at least one air pollutant. The perception of the local air quality was also very different between populations, with 61% of the sub-population considering it poor or very poor, while only 14% of the general population had the same perception, which highlights the different levels of concern between populations. A weak knowledge about air pollutants (50% of the general population could not identify any air pollutant) and an erroneous perception of the contribution of the different pollution sources to air quality levels were found. More than 50% of the respondents of both populations were considered to not have enough information regarding the air quality in their area of residence, with the national air quality database being unknown to almost everyone. Overall, strong efforts should be made to increase the awareness about the importance of air quality, which may promote a higher acceptance of the implementation of future actions to improve air quality.

Authors: Richardson Leigh Ann , Izuora Kenneth , Basu Arpita
Published: October 2022

Atherosclerosis is the underlying cause of cardiovascular diseases (CVD) and is interrelated to stroke, heart attack, and heart failure. The Mediterranean Diet (MedDiet) has been closely associated with reduced CVD morbidity and mortality, but research is not well explored for this relationship in individuals with diabetes (who experience greater CVD morbidity and mortality than individuals without diabetes). The aim of this review was to explore the literature related to the MedDiet and atherosclerosis and associated risk factors in individuals with and without diabetes. In total, 570 articles were identified, and 36 articles were included. The articles were published between 2011 and 2021. Platforms used for the search were PubMed, Scopus, Cochrane Library, and ProQuest. Our literature search included clinical and observational studies. Clinical studies revealed the MedDiet was associated with improved biomarkers, plaque, and anthropometric measurements that are associated with atherosclerosis and CVD. Observational studies identified associations between the MedDiet and lower presence of atherosclerosis, improved vascular aging, and increased endothelial progenitor cells. However, most of the studies took place in Mediterranean countries. Further research is needed to better understand the long-term effects the MedDiet on atherosclerosis and its associated risk factors in diverse populations to include individuals with and without diabetes.

This paper uses the environmental information announcement system as a quasi-natural experiment, cleaning China’s Industrial Enterprise Pollution Database, a unique and comprehensive firm-level database, and merges it with China’s Industrial Enterprise Database. Then, we use the difference-in-differences model to test the effect of environmental information announcements on firm pollution emissions and the transmission mechanism. The empirical results found that environmental information announcement has a significant environmental performance improvement effect. That is, environmental information announcements can significantly reduce pollution emissions. Moreover, the effects of environmental information announcement differ significantly under different regions, city levels, and environmental regulatory intensities. Specifically, in the eastern region, first-class cities, and regions with higher environmental regulations, the emission reduction effects of enterprises are more obvious. Further transmission mechanism test results show that environmental information disclosure has a dual emission reduction mechanism of internal driving and external pressure. Front-end of technological innovation and end-of-end environmental governance are important manifestations in internal driving. Under external pressure, companies will reduce production so as to achieve the goal of reducing pollution emissions.

The consequences of climate change are becoming increasingly evident and highlight the important interdependence between the well-being of people and ecosystems. Although climate change is a global phenomenon, its causes and consequences vary dramatically across territories and population groups. Among settings particularly susceptible to health impacts from climate change are cities with a Mediterranean climate. Here, impacts will put additional pressure on already-stressed ecosystems and vulnerable economies and societies, increasing health inequalities. Therefore, this article presents and discusses a conceptual framework for understanding the complex relationship between climate change and health in the context of cities with Mediterranean climate from a social and climate justice approach. The different elements that integrate the conceptual framework are: (1) the determinants of climate change; (2) its environmental and social consequences; (3) its direct and indirect impacts on health; and (4) the role of mitigation and adaptation policies. The model places special emphasis on the associated social and health inequalities through (1) the recognition of the role of systems of privilege and oppression; (2) the distinction between structural and intermediate determinants of climate change at the root of health inequalities; (3) the role of individual and collective vulnerability in mediating the effects of climate change on health; and (4) the need to act from a climate justice perspective to reverse health inequities.
An Exploratory Study of Beryllium and UK Soft Touch Regulation: An Enduring Example of Weaknesses of UK Occupational Health and Safety Governance
Authors: Watterson Andrew , Beck Matthias
Published: October 2022

Smart regulation, better regulation, responsive regulation, business-friendly regulation and voluntary ‘self-regulation’ have their origins deeply embedded in UK policies in the 20th century. Their aim generally is to reduce workplace regulatory obligations on employers. This can overtly or covertly undermine efforts to improve working conditions. In the UK, the historical control and regulation of beryllium (a toxic metal used in industry) illustrates this problem, and as we illustrate through an exploratory analysis of original archival material and official publications. Soft touch regulation of the metal beryllium was developed within the UK semiconductor industry when tighter controls were proposed in the 1960s and 1970s. Historical industry, government and science responses to health and safety information about beryllium provide important lessons for current debates on occupational health and safety.
The Slope Safety, Heavy Metal Leaching, and Pollutant Diffusion Prediction Properties under the Influence of Unclassified Cemented Paste Backfill in an Open Pit

Published: October 2022

Open-pit unclassified cemented paste backfilling (OPUCPB) methods have not only addressed the disposal problems of tailings but also eliminated geological hazards of high and steep open pit slopes and created conditions for ecological restoration of the open pit in the future. In this paper, slope safety simulations, heavy metal leaching, groundwater monitoring, and pollutant diffusion predictions were examined to evaluate the slope safety pattern and environmental protection enabled by OPUCPB. The results showed that: (1) The safety factor of the open pit slope was proportional to the height of OPUCPB operation. Under the condition of seismic force and seepage field, the safety factor of slope B was increased from 1.188 to 1.574 by OPUCPB. (2) The toxic and harmful components in tailings were significantly stabilized by the OPUCPB. Under the conditions of acid leaching and water leaching, the quality of the leaching solution met the requirements of the class III limit of groundwater (GB/T14848-2017). (3) The monitoring results of groundwater quality around the open pit showed that the OPUCPB had no effect on groundwater, and the water quality met the requirements of the class III limit of groundwater (GB/T14848-2017). (4) Considering the diffusion prediction of pollutants and groundwater under extreme conditions, it was found that the pollution process is slow, and the shortest time required for pollutants to reach the standard limit is 232 d at a distance of 50 m from the leakage point. Therefore, the influence of OPUCPB can be controlled, and this method can achieve improved reclamation of open pits and safety treatment of tailings. It was worth popularizing and applying in mining enterprises.

The management of postoperative bleeding is mandatory in patients receiving anticoagulants. In this case report, we introduce a fully digital workflow for surgical splint fabrication to prevent postoperative bleeding in patients receiving anticoagulants and/or at risk of inadvertent extraction of a mobile tooth during impression making. An 87-year-old woman using apixaban had a left mandibular canine that required extraction due to chronic apical periodontitis. A digital impression was obtained using an intraoral scanner. First, the tooth to be extracted was deleted using three-dimensional (3D) computer-aided design (CAD) software (Geomagic Freeform, 3D Systems) and a stereolithography (STL) file was exported. This modified STL file was imported into another CAD software (3Shape Dental System, 3Shape) and a surgical splint was designed. The splint was fabricated using a 3D printer (Form 3; Formlabs) and light-curable resin (Dental LT Clear, Formlabs) and was delivered after the tooth extraction. The patient was followed-up 2 days after the extraction; no postoperative bleeding was detected and the surgical splint was removed. The additively manufactured surgical splint fabricated using a fully digital workflow was efficacious for managing postoperative bleeding after a dental extraction.
