Cross-Sectional Analysis of Fall-Related Factors with a Focus on Fall Prevention Self-Efficacy and Self-Cognition of Physical Performance among Community-Dwelling Older Adults
Authors: Hayashi Shintaro , Misu Yuka , Sakamoto Toshimasa , Yamamoto Taisei
Published: January 2023

This study aimed to determine how fall prevention self-efficacy and degree of deviation in self-cognition of physical performance, which have recently received attention for their potential to explain falls in combination with a wide variety of fall-related factors, as well as affect falls. Older adults using day-care services (n = 27 with six men, mean age: 81.41 ± 7.43 years) were included in this study. Fall history in the past year, the modified fall efficacy scale (MFES), and physical performance and cognition errors were examined by evaluating the functional reach test (FRT), the stepping over test, and the timed up and go test (TUG), along with a questionnaire. In the fall (n = 14) and non-fall (n = 13) groups, logistic regression analysis using Bayesian statistical methods was used to identify factors associated with falls. The odds ratios for the MFES ranged from 0.97 to 1.0, while those of cognition-error items ranged from 3.1 to 170.72. These findings suggested that deviation in self-cognition of physical performance, particularly overestimation of timed cognitive ability, was a factor with more explanatory power for fall history. Future studies should analyze differences by disease and age group, which were not clarified in this study, to identify more detailed fall risk factors.

Published: January 2023

Ambient Assisted Living (AAL) is a medical surveillance system comprised of connected devices, healthcare sensor systems, wireless communications, computer hardware, and software implementations. AAL could be used for an extensive variety of purposes, comprising preventing, healing, as well as improving the health and wellness of elderly individuals. AAL intends to ensure the wellbeing of elderly persons while also spanning the number of years seniors can remain independent in their preferred surroundings. It also decreases the quantity of family caregivers by giving patients control over their health situations. To avert huge costs as well as possible adverse effects on standard of living, classifiers must be used to distinguish between adopters as well as nonadopters of such innovations. With the development of numerous classification algorithms, selecting the best classifier became a vital and challenging step in technology acceptance. Decision makers must consider several criteria from different domains when selecting the best classifier. Furthermore, it is critical to define the best multicriteria decision-making strategy for modelling technology acceptance. Considering the foregoing, this research reports the incorporation of the multicriteria decision-making (MCDM) method which is founded on the fuzzy method for order of preference by similarity to ideal solution (TOPSIS) to identify the top classifier for continuing toward supporting AAL implementation research. The results indicate that the classification algorithm KNN is the preferred technique among the collection of different classification algorithms for the ambient assisted living system.

Epidermoid cysts are most often benign cystic lesions, with uterine cervical localisation being very unusual. We present the case of a 52-year-old female patient diagnosed with an epidermoid cyst at the level of the uterine cervix. A bioptic and haemostatic uterine curettage was performed, followed by total hysterectomy with bilateral adnexectomy. The histopathologic analysis and immunohistochemical essay of the resection specimens confirmed the cervical epidermoid cyst. The presence of high-risk HPV (human papillomavirus) was only seen in the cervical mucosa. The exact etiopathogenesis is unknown, but postpartum cell implantation of reminiscent embryonic tissue can be involved in the development of these lesions.

Published: January 2023

The purpose of this study was to evaluate the effectiveness of three different physical training approaches to improving cadets’ fitness variables. Retrospective data for male and female land management law enforcement officers attending a 15-week training program at three separate time points were provided for analysis. The time points reflected the three different training approaches, including calisthenic training (CT) = 83, functional fitness training (FT) = 90, and strength training (ST) = 110. Inferential data analysis was used to find which mode of exercise had the greatest impact on body composition, cardiovascular endurance, muscular strength, agility, and flexibility. All groups displayed decreases in body fat percentage, with weight loss being more significant within the CT and FT groups, while the ST group increased in body weight. The CT group had the greatest flexibility increases compared to the FT and ST groups. ST training elicited significantly smaller changes in cardiovascular endurance than the FT and CT groups. ST training showed greater improvements in lean mass, while CT and FT showed greater increases in flexibility and endurance. These results suggest that training protocols can increase performance and optimize the abilities to perform job tasks in tactical athletes.

Published: January 2023

Inspiratory muscle training (IMT) is effective in improving postural stability and balance in different clinical populations. However, there is no evidence of these effects in soccer players. A single-blind, two-arm (1:1), randomized, placebo-controlled pilot study on 14 soccer players was performed with the main aim of assessing the effect of IMT on static balance, and secondarily, of examining changes in the respiratory muscle function. The experimental group (EG) received an IMT program with progressive intensity, from 20% to 80%, of the maximal inspiratory pressure (MIP). The sham group (SG) performed the same program with a fixed load of 20% of the MIP. Static balance and respiratory muscle function variables were assessed. A two-factor analysis of variance for repeated measures was used to assess differences after training. Statistical significance was set at p < 0.05. Significant increases were observed in the EG on length of sway under eyes open (from 2904.8 ± 640.0 to 3522.4 ± 509.0 mm, p = 0.012) and eyes closed (from 3166.2 ± 641.3 to 4173.3 ± 390.8 mm, p = 0.004). A significant increase in the maximal voluntary ventilation was observed for both groups (EG p = 0.005; SG p = 0.000). No significant differences existed between the groups. IMT did not improve the static balance in a sample of soccer players. Conducting a high-scale study is feasible and could refine the results and conclusions stemming from the current pilot study.

Authors: Gómez-Pérez Vanesa , Escrivá Peiró Dolores , Sancho-Cantus David , Casaña Mohedo Jorge
Published: January 2023

Background: Patient safety is a public health problem worldwide. In situ simulation (ISS) arises as a learning strategy that allows health professionals to immerse themselves in a real environment without endangering the patients until they have learned the skills needed, thus increasing the quality of care. This systematic review aimed to verify the efficacy of the use of “in situ simulation” as a method that will allow health professionals to increase patient safety in Intensive Care Units after the situation experienced during the pandemic caused by the COVID-19 virus. Methods: Seven studies were reviewed using the PRISMA methodology for systematic reviews. The CASPe guide was used to assess the quality of the manuscripts. Results: The main topics that emerged from this review in relation to in situ simulation were as follows: looking at aspects such as patient self-perception of safety, adverse events, interprofessional communication and health system organization in relation to in situ simulation. Conclusions: The adequate implementation of in situ simulation after the COVID-19 pandemic in ICU services is shown to be an efficient and effective strategy to promote improvement in the attitudes on a culture of safety and teamwork of professionals.

Authors: Alanazi Abdullah , Alghamdi Ghada , Aldosari Bakheet
Published: January 2023

Introduction: Information technology is vital to support dental care services and is yet to be thoroughly investigated. This study aims to assess the dentists’ needs and requirements for health records from dental care providers’ perspectives. Methods: In-depth interviews were conducted with dentists during clinic practices. This qualitative research method involves exploring the information and functions dentists use to obtain information from EHR. The target population is the dental staff interacting with the patients and accessing the electronic health records in the government and private sectors. Results: Thirty-five dentists were interviewed directly after the treatment session and asked four pre-defined questions, the dentists’ needs were collected, and the met and unmet needs were presented. The interview results revealed 42 needs (15 were met and 27 were unmet), with an average of 1.17 needs per session. The information needs were categorized into foreground and background information needs and reported in nine main themes. Discussion: The interviews were analyzed, and as a result, nine themes were generated: chief complaints and symptoms, medical and health history, medications, visual representations of the problem, treatment procedures, X-ray services, needs related to advanced features, needs related to insurance coverage, and finally, information needs related to the treatment environment. The required information and functions mentioned by dentists in the study emphasize the need for integrated modules for oral and medical care services. Generally, it is evident that dentists have substantial unmet needs, and the desired EHR should have functions that cover all dentists’ needs. Conclusion: The study’s findings demonstrate gaps between current and desired EHR to serve dentists’ needs. Dentists need better access to patient history and medical information, progress notes, and X-rays to provide visualization tools for problems and patient charts. Moreover, essential needs were related to messaging capability, educational tools, availability of tutorial videos, and accessing external resources. Information needs were described and should be considered when designing EHR to meet all dentists’ needs.

Published: January 2023

The aim of this study was to understand the perceptions, understanding and experiences of the families of individuals with autism spectrum disorder (ASD) related to adapted physical activity (APA), and their educators, through their use of metaphors. The research was based on systematic content analysis in the qualitative research model. The data were collected based on metaphors. The participants included 85 families of individuals with ASD attending private institutions operating in Istanbul and Ankara. The metaphors used by the families were examined under two headings: adapted physical activities, and educators. When the metaphors used to describe APA were examined, four themes emerged, education, emotion, support and development, and these themes were divided into the categories of guidance, skill, affection, and care. When the metaphorical perceptions of educators were examined, three themes emerged: education, emotion, and social adaptation. These were further categorized as experience, knowledge, entertainment, independence, happiness, and treatment. The metaphors showed that experiences in APA support increased self-confidence for individuals with autism spectrum disorder and support the social adaptation of individuals who have the opportunity to apply knowledge and experience. This research shows that families have positive perceptions of APA educators and their lessons.
Prevalence and Causes of Elective Surgical Cancellations: Findings from a Rural Tertiary Hospital in the Eastern Cape, South Africa
Authors: Sukwana Abongile , Mrara Busisiwe , Oladimeji Olanrewaju
Published: January 2023

Background: Cancellations of elective surgeries adversely affect the patient, hospital staff, facility, and health system. Cancellations potentially result in hospital financial losses, theatre inefficiency, and substandard patient care. A common benchmark for the cancellation rate of elective surgeries is less than five percent, and most operating rooms fall short of this standard. There is a paucity of data on the rates and causes of elective surgical cancellations in rural, resource-limited settings. This study aimed to determine the prevalence of elective surgery cancellations, the causes for such cancellations, and the surgical disciplines most affected at Nelson Mandela Academic Hospital (NMAH). Methodology: This was an observational, descriptive, cross-sectional review of operating theatre records from January 2019 to July 2019. The prevalence and main causes of elective case cancellations were determined. The causes were classified, and the most affected surgical departments and patient characteristics were identified. Results: The prevalence of elective surgical case cancellations was 14.4% in our hospital, higher than the international benchmark of 5%. Patient-, facility-, and surgical-related factors were the leading causes of cancellations, and avoidable cancellations were mostly surgical- and anaesthetic-related. Ophthalmology was the most affected, followed by gynaecology and general surgery, with plastic surgery being the least affected. The most common patient-related factors were nonattendance and uncontrolled medical conditions, while overbooking was the most common surgical reason. Abnormal investigatory results and unfit status were the most common anaesthetic reasons. Facility-related issues included the lack of theatre time, equipment scarcity or malfunction, and staff unavailability. Most cancellations were unavoidable, but with careful planning, could be avoided. Conclusion and recommendations: This study identified challenges with theatre efficiency in a rural, resource-limited setting that call for the cooperation of multidisciplinary teams of surgeons, anaesthetists, nursing staff, and health care policymakers.

Published: January 2023

The aim of this study was to evaluate knowledge of oral cancer risk factors among international dental and medical students at the Lithuanian University of Health Sciences (LSMU). A cross-sectional study was conducted among international medical and dental students at the LSMU in 2018–2019. In total, 253 students participated, for a response rate of 76.2%. An anonymous self-administered English questionnaire, consisting of 18 items, covered background information (gender, faculty and academic study year), and statements about risk factors for oral cancer and attitudes towards the prevention and treatment of oral cancer. The fifteen statements had the following answer options: yes, no and I don’t know. The statistical data analysis was performed using SPSS version 22. Overall, a good, fair and poor knowledge of oral risk factors was reported by 15.02%, 56.92% and 28.06% of the participants, respectively. The mean score for knowledge of oral cancer risk factors was 10.01 (SD = 2.56), which was defined as fair knowledge. Cronbach’s alpha was found to be 0.78 (a good value). Bartlett’s sphericity test and the KMO index were adequate (χ2 = 677.563, p < 0.001; KMO = 0.788). This study demonstrates a lack of knowledge of oral cancer risk factors among international medical and dental students.

Authors: Choudhury Avishek , Kuehn Annabella , Shamszare Hamid , Shahsavar Yeganeh
Published: January 2023

Background: College students are one of the most susceptible age groups to mental health problems. With the growing popularity of mobile health (mHealth), there is an increasing need to investigate its implications for mental health solutions. This review evaluates mHealth interventions for addressing mental health problems among college students. Methods: An online database search was conducted. Articles were required to focus on the impact of mHealth intervention on student mental health. Fifteen of the 487 articles, initially pulled from the search query, were included in the review. Results: The review identified three primary aspects of mental health: depression, anxiety, and stress. Research that found statistically significant improvements following mHealth intervention involved study durations between four and eight weeks, daily app use, guided lessons using cognitive behavioral therapy, acceptance and commitment therapy, and meditation. The review’s findings show that future work must address the concern of digital divide, gender and sex differences, and have larger sample sizes. Conclusions: There is potential to improve depressive symptoms and other similar mental health problems among college students via mobile app interventions. However, actions must be taken to improve barriers to communication and better reach the younger generations.

Published: January 2023

Wound assessment is essential for evaluating wound healing. One cornerstone of wound care practice is the use of clinical guidelines that mandate regular documentation, including wound size and wound tissue composition, to determine the rate of wound healing. The traditional method requires wound care professionals to manually measure the wound area and tissue composition, which is time-consuming, costly, and difficult to reproduce. In this work, we propose an approach for automatic wound assessment that incorporates automatic color and measurement calibration and artificial intelligence algorithms. Our approach enables the comparison of images taken at different times, even if they were taken under different lighting conditions, distances, lenses, and camera sensors. We designed a calibration chart and developed automatic algorithms for color and measurement calibration. The wound area and wound composition on the images were annotated by three physicians with more than ten years of experience. Deep learning models were then developed to mimic what the physicians did on the images. We examined two network variants, U-Net with EfficientNet and U-Net with MobileNetV2, on wound images with a size of 1024 × 1024 pixels. Our best-performing algorithm achieved a mean intersection over union (IoU) of 0.6964, 0.3957, 0.6421, and 0.1552 for segmenting a wound area, epithelialization area, granulation tissue, and necrotic tissue, respectively. Our approach was able to accurately segment the wound area and granulation tissue but was inconsistent with respect to the epithelialization area and necrotic tissue. The calibration chart, which helps calibrate colors and scales, improved the performance of the algorithm. The approach could provide a thorough assessment of the wound, which could help clinicians tailor treatment to the patient’s condition.

Published: January 2023

This study aims to report what motivates individuals to be physically active, to determine whether motivating factors influence physical activity (PA) levels, and whether this differs across the lifespan. This is a cross-sectional study with 498 individuals: 117 adolescents, 306 adults, and 75 older adults. PA was assessed using Baecke’s questionnaire, and motivating factors for practicing sports were investigated using a scale with twelve questions. The factor analysis identified three motivating factors for sports practice: psychosocial, bodily, and well-being. The scale’s overall reliability and internal consistency indicated a Cronbach’s alpha of 0.885. The analysis of covariance (ANCOVA) adjusted for sex indicated the three factors as having a significant effect on PA (p < 0.050); however, only the well-being factor showed a significant interaction with age groups (p = 0.023, ηp2 = 0.030). Subsequently, the effect of the well-being factor on PA scores in each age group was explored through regression analyses. Only older adults showed a significant association in the unadjusted [OR = 0.378, p = 0.001, R2 = 0.243] and the sex-adjusted analysis [OR = 0.377, p = 0.001, R2 = 0.288]. These results help us to better understand the underlying motivational reasons in different age groups for engaging in sports.

Background and Aim: Spontaneous bacterial peritonitis (SBP) is a common infection in liver cirrhosis. This systematic review and meta-analysis provide detailed information on the prevalence of SBP among hepatitis B virus (HBV) and hepatitis C virus (HCV)-related liver cirrhosis globally. Methods: A systematic search for articles describing the prevalence of SBP in HBV and HCV-related cirrhosis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Our search returned ten (10) eligible articles involving 1713 viral cirrhosis cases representing eight (8) countries. A meta-analysis was performed on our eligible studies using the random effect model. A protocol was registered with PROSPERO (CRD42022321790). Results: The pooled prevalence of SBP in HBV-associated cirrhosis had the highest estimate [8.0% (95% CI, 2.7–21.0%; I2 = 96.13%; p < 0.001)], followed by SBP in HCV-associated liver cirrhosis [4.0% (95% CI, 1.3%–11.5%; I2 = 88.99%; p < 0.001)]. China (61.8%, CI: 57.1–66.3%), the USA (50.0%, CI: 34.6–65.4%), and Holland (31.1%, CI: 21.6–42.5%) had the highest estimate for SBP in HBV associated liver cirrhosis, SBP in HCV associated liver cirrhosis and SBP in HBV + HCV associated liver cirrhosis respectively. There was a significant difference in the prevalence of SBP in viral hepatitis-associated liver cirrhosis with the year of sampling and method of SBP detection at P < 0.001. There was an increase in SBP incidence at the beginning of 2016 across the liver cirrhosis in this study. Conclusion: The findings of this review revealed a rise in the incidence of SBP in viral hepatitis over the last decade. The latter indicates a possible future rise in the global prevalence of SBP among HBV and HCV-related liver cirrhosis.

Background: This study was conducted to assess the level of knowledge and awareness of hypothyroidism and its neuropsychiatric clinical manifestations among the Saudi population. Methods: This was a cross-sectional study employing a convenient sampling technique, conducted between February and May 2022. A questionnaire was distributed online to all participants in all five regions. Results: In this survey, a total of 2016 Saudi citizens participated. When asked about depression, more than half of the participants (59.6%) correctly identified depression as one of the neuropsychiatric clinical symptoms of hypothyroidism. Nearly half of the participants (47.5%) were unaware that anxiety was not a neuropsychiatric manifestation of hypothyroidism. With a percentage of 91.0%, the majority of participants exhibited poor knowledge. The regression analysis showed that males have significantly reduced knowledge about hypothyroidism than females (coefficient −3.686, p-value < 0.0001). Similarly, those who have “enough income and can save” were more knowledgeable than others (coefficient 0.731, p-value < 0.02). Regarding the source of information, journals provide three times more information (p-value 0.0001), and healthcare practitioners provides four times more information as compared to family and friends (p-value 0.0001). Conclusion: Due to a lack of knowledge about hypothyroidism and its complications, symptoms, risk factors, and treatment, the most viable solution to these misconceptions would be to implement a variety of educational programs to increase public awareness of this issue.
Woaded Blue: A Colorful Approach to the Dialectic between Written Historical Sources, Experimental Archaeology, Chromatographic Analyses, and Biochemical Research
Authors: Cardon Dominique , Koren Zvi C. , Sumi Hisako
Published: January 2023

Research into the sustainability of natural, potentially renewable, resources is one of the major issues of our time. It naturally includes the quest for sustainable sources of colorants for textiles, cosmetics, and food. In industrialized countries, natural dyeing with plants and a few species of coccid insects was practiced on a large scale for centuries before synthetic colorants were developed. Therefore, historical documents on the growing of dye plants and dyeing processes offer a relevant basis from which to start reconsidering the potential of natural colorants in our time. However, written sources need to be completed by experimental archaeologists to allow a scientific understanding of the biochemical reactions at work in the historical processes described. The results of such interdisciplinary research can then inspire contemporary programs to revive the production of natural dyes. The long history of dyeing blue with woad, Isatis tinctoria L., is revisited here as an illustration of the fruitful complementarity of sources and approaches. This article presents a step-by-step re-assessment of the production chain of woad as described in historical texts, from the growing of the plant to its use as a source of indigo in the woad and indigo vats. The experimental reconstitution of the processing of woad leaves into couched woad allowed us to follow the evolution of the composition and proportions of indigoid colorants in the leaves by HPLC analyses. Additionally, HPLC analyses allowed a comparison of the respective indigoid contents of couched woad and sukumo, the form of indigo dye resulting from another couching process, traditionally used in Japan for dyers’ knotweed, Persicaria tinctoria (Ait.) H. Gross. The reconstitution of the 18th century woad and indigo vat process allowed investigations into the bacterial flora associated with the use of couched woad in vat liquors, which were found to contain different indigo-reducing bacteria, including two distinct strains of a new indigo-reducing species.
The Usefulness of the Johari Window for the Cultural Heritage Planning Process
Authors: Spennemann Dirk H. R.
Published: January 2023

The standard heritage planning process follows the trajectory of identification, nomination, evaluation, listing and protection. The epistemology of the nominations and valuations is only rarely, if ever, examined. The Johari window was developed by the psychologists Joseph Luft and Harrington Ingham as a tool to examine group dynamics, in particular an individual’s position in, and their relationship and interactions with others in a group. This paper examines the usefulness of the Johari window for the Cultural Heritage Planning Process. Based on the interrelationship of what oneself and others know about each other and are prepared to divulge, the Johari window allows to conceptualize overlapping levels of knowledge and ownership within five newly defined epistemological domains. It also serves as an analytical tool to systematically query the heritage universe of a community and thereby examine the composition and comprehensiveness of heritage registers as well as nominations that have been put forward.

Authors: Geleta Birtukan Tolera , Lee Je-Chang , Heo Jae-Yun
Published: January 2023

This study evaluated unripe fruits of ten apple cultivars removed during fruit thinning for their antioxidant activity and mineral content. The unripe fruits were collected from Chuncheon and Jeongseon located at Gangwon-Do of Korea. Antioxidant activities such as total phenolic content (TPC), total flavonoid content (TFC), DPPH (2,2-diphenyl-1-picrylhydrazyl) activity, FRAP (Ferric reducing antioxidant power), vitamin C and mineral contents were measured. In the unripe fruits obtained from Chuncheon and Jeongseon, TPC was in the range 8.97–81.4 and 7.11–42.15 mg GAE/g, TFC was in the range 9.38–33.81 and 6.83–19.24 mg QE/g, DPPH was in the range 27.17–82.58 and 29.73–73.24, FRAP was in the range 33.54–371.12 and 26.76–185.69 µM trolox /g, and Vitamin C was in the range 1.1–4.9 and 1.1–2.8 mg/AA/g, respectively. Among the cultivars tested, ‘Hongro’ and ‘Honggeum’ had consistently highest antioxidant activity, while ‘Summer King,’ ‘Tsugaru,’ and ‘Arisoo’ had the lowest value. ‘Picnic’ had the highest mineral contents expect P and K in Joengsoen, while ‘Summer King’ and ‘Tsugaru’ had the lowest value in both locations. These differences could be due to the genetic characteristics and/or their growth environments. These results could provide information to help with better utilization of thinned unripe fruits of apples in Korea.
A Study on the Characteristics of Buds and Flowers in Pomegranate: Differences among Cultivars
Authors: Ferrara Giuseppe , Porfido Carlo , Terzano Roberto , Sarkhosh Ali , Mazzeo Andrea
Published: January 2023

The growing cultivation of pomegranate and the interest of consumers in the nutraceutical properties of the fruit have not yet spurred similar increases in the knowledge base of some important botanical and physiological aspects of this species, such as bud differentiation. The aim of this research was to study the bud morphology of four pomegranate cultivars (‘Comune S. Giorgio’, ‘Wonderful’, ‘Ki-Zakuro’, and ‘Haku Botan’) to better clarify the bud differentiation process. In all four cultivars, the number and the position of the buds were variable, from a typical two buds per node to a single bud or more (3). Two types of buds were observed: small and thin on the twigs (short, medium, and long) and large and round on the spurs; large buds were also observed on twigs but in a reduced number. Flowers showed differences among the cultivars, with a larger number of petals in ‘ornamental’ cultivars because of the petaloidy. Hermaphrodite flowers were larger and longer than the staminate flowers and also more abundant. Moreover, flowers developing from a flower bud were longer than flowers developing from mixed buds. The presence of an undifferentiated meristem, starch grains in the protective scales, and two small transition leaves were observed in all the types of buds from summer to the end of endodormancy in all cultivars. However, a dome-shaped meristem was observed in a few flower buds. Our observations indicate pomegranate behaves as a species for warm, sub-tropical, and tropical areas more than for temperate ones.

Published: January 2023

Epigallocatechin gallate (EGCG) is an important contributor to bitterness and astringency in summer tea leaves; however, the transcriptional regulatory mechanisms of EGCG biosynthesis remain unclear. In this study, EGCG content was significantly decreased after foliar spraying with nano-Se fertilizers in tea leaves. A WRKY transcription factor (TF), CsWRKY70, was found to be positively related to EGCG content. The open reading frame of CsWRKY70 was 891 bp encoding 296 amino acids. CsWRKY70 is localized to the nucleus and has transcriptional activation activity. The electrophoretic mobility shift assay indicated that CsWRKY70 can directly bind to the promoters of CsLAR and CsUGT84A containing W-box (5′-C/TTGACT/C-3′) sequences. Dual-luciferase reporter experiment verified that CsWRKY70 activated CsLAR and CsUGT84A expressions in tobacco leaves. In summary, these results demonstrated that CsWRKY70 may reduce EGCG biosynthesis by inhibiting the CsLAR and CsUGT84A expressions under nano-Se treatment. Our findings provide new insight into the regulatory mechanism of WRKY TFs involved in catechin biosynthesis and offer a theoretical basis for breeding low or high EGCG content tea cultivars.

Many individuals practicing field-based research are subjected to sexual harassment and assault. This fact holds true for people engaged in archaeological field research and may be true for students who are just learning field methods while enrolled in an archaeological field school. We review some of our current research on the means of reducing and preventing sexual harassment and assault at archaeological field schools, as well as ways to create safer, more inclusive learning spaces. Additionally, we suggest that for the discipline to advance field school teaching and learning, we, as field directors, must situate ourselves as active and advocacy anthropologists: an approach that puts our students as a central focus when developing field-based pedagogy. As the authors of this work, we review our identities and positionality in conducting this research and in making meaning from the data we have collected.

The mobility of a metal in mining-impacted sediments is determined by the environmental conditions that influence the metal’s oxidation state and bonding environment. Coeur d’Alene Lake, USA, has been impacted by legacy mining practices that allowed the hydrologic transport of mining waste to the lakebed, resulting in substantial amounts of redox-sensitive Fe and Mn along with Ag, As, Cd, Cu, Hg, Pb, Sb, and Zn. Future lake conditions may include algal blooms and additional algal detritus at the sediment–water interface, which may alter Fe and Mn forms that can influence their, and other metal(loid)s, mobility during seasonal anoxia. Cores of the lakebed sediments were exposed to anoxic and anoxic + algal detritus conditions for 8 weeks. Sediment samples were collected biweekly for analysis of Fe and Mn oxidation states and bonding environments by synchrotron-based X-ray absorption spectroscopy. Over the 8-week period and at a location 12.5 cm deep in the sediments, anoxic and anoxic + algae conditions produced limited changes in Fe and Mn oxidation states and bonding environments. At a location 2.5 cm below the sediment–water interface, the anoxic condition promoted a relatively stable environment in which Fe and Mn oxidation states and bonding environments did not vary greatly during the experiment. At the 2.5 cm depth, the anoxic + algae condition substantially altered the Mn oxidation state distribution and bonding environment, but this condition did not strongly influence the Fe oxidation state distribution or bonding environment. The anoxic + algae condition increased the presence of Mn3+, produced Mn4+ at select times, altered the Mn bonding environment, and temporarily increased the release of Mn into porewater. The algae influence on sediment and porewater Mn likely occurred because of the increased formation of organo-Mn complexes produced during algae-enhanced enzymatic processes. The lack of influence of algal detritus on sediment and porewater Fe and the formation of soluble organo-Mn complexes may limit the potential increase in the mobility of other metal(loid)s with future lake conditions.

Older people in nursing homes are at a high risk of being infected by coronavirus disease 2019 (COVID-19). They also experienced nursing home lockdowns that harm their psychological wellbeing. Better support for this vulnerable population requires understanding their perceptions of challenges and coping strategies during the COVID-19 pandemic. A qualitative descriptive study was conducted using semi-structured interviews. Thematic analysis approach was used to analyze the data. Participants were recruited from six nursing homes in three cities in Hunan Province, China. Fourteen nursing home residents participated in the study. Four themes were identified from interviews and described as: mental stress and coping strategies, self-regulation to respond to lockdown, the lack of social connection and coping strategies, and the need for medical care services and coping strategies. This study revealed that nursing home residents perceived stress during the nursing home lockdown, but they reported initiating activities to maintain health and connections with their families and peers. Resilience improvement interventions are necessary to enable residents’ autonomy and develop their resilience in coping with difficulties and hardship during crises. The findings also indicate that a supportive environment with interactions from families, peers, and staffs played a key role in enabling residents’ positive health and wellbeing during the lockdown.

Breast cancer (BC) in younger age is a critical and potentially traumatic experience that can interrupt the continuity of self-narrative during a crucial phase. In the Narrative Identity framework the translation of memories into autobiographical narratives is an internal and external process that plays a key role in meaning-making, social relationships and self-coherence. The aim of this study is to examine the role and function that autobiographical memory narratives (AMN) play in the process of adaptation to BC medical treatment. Seventeen BC women below 50 years received prompts to provide autobiographical memory narratives at four phases during their treatment (pre-hospitalization-T1-post-surgery-T2-chemo-radio therapy-T3-follow-up-T4). The Emotional Processing Scale (EPS) was also administered. In all, 68 AMN were collected. A three step procedure of data analysis was conducted. The first one, an empirically-derived memory coding manual to analyze key dimensions of AMN was developed: Agency; Emotional Regulation and Interpersonal Relations. Findings show a particular vulnerability in narrative identity faced by BC women during the shift from T1-T3. In the second one, an emotional coping profile for each woman focusing on the shift from T1-T3 was created. For the third step, these profiles were compared with the EPS scores. The final results suggest the capacity of the AMNs to differentiate the women’s emotional adaptation over the course of the BC treatment. Despite the study’s limitations, it supports the use of AMN as clinical device to construct a deeper knowledge and profiling trajectory of how women have internalized and elaborated past encounters with illness and help providers, as well as their prior experience of bodily/psychological health and integrity. This information adds to an understanding of their current efforts at recovery and adaptation. In this way we believe that the recollection of narrative memories, not only at the end of the cancer treatment but also during its process, could help the women to mend the broken continuity of their narrative self, as they seek to maintain a healthy balance of internal resources across their past, present, and projected future.
Revisiting the Impact of Environmental Regulation on Green Total Factor Productivity in China: Based on a Comprehensive Index of Environmental Regulation from a Spatiotemporal Heterogeneity Perspective
Authors: Jiang Lei , Chen Yuan , Zhang Bo
Published: January 2023

Promoting greener and sustainable development is one of the main goals of the most recent 14th Five-Year Plan (i.e., 2021–2025). Environmental regulation is seen as fundamental to green transformation and an important way for all of China to reach a high-quality and sustainable development mode. However, large spatial disparities exist across the different regions in China, so formulating region-oriented environmental regulatory policies to achieve regional high-quality and sustainable development is now a matter of great practical significance. In the present paper, we analyze this problem and begin by calculating the high development level measured through the Green Total Factor Productivity (GTFP) of 259 Chinese cities. Thereafter we construct a comprehensive index of environmental regulation through the linear weighted-sum method. Lastly, we investigate the spatiotemporal heterogeneity of the impact of environmental regulation on GTFP using a Geographically and Temporally Weighted Regression (GTWR) model. We find that: (1) From the spatial dimension perspective, the impact of environmental regulation of Chinese cities on GTFP is either linear (monotonically increasing or decreasing), non-linear (U-shaped or inverted U-shaped), or nonsignificant. Most cities have a U-shaped relationship, indicating that environmental regulation first inhibits GTFP at the early stage, but then promotes it. There are also significant differences among cities in the turning points of environmental regulation; (2) From the time dimension perspective, the number of cities is on the rise having monotonically decreasing impacts of environmental regulation on GTFP. Furthermore, even for the same city, the relationship between the two variables shows different characteristics in different years; (3) The impact of five control variables on GTFP may also vary from one city to another over the sample period, also presenting spatiotemporal heterogeneity effects. Consequently, the formulation and implementation of environmental regulatory policies should not only adapt to local conditions but also choose reasonable and effective measures to achieve high-quality development targets.
