Effects of Environmental Stress on the Pollen Viability of Ornamental Tree-Species in the City of Granada (South-Eastern Spain)
Authors: Ramírez-Aliaga Priscila , Foyo-Moreno Inmaculada , Cariñanos Paloma
Published: December 2022

Atmospheric conditions, as well as pollutants, can induce changes in the viability and germinability of the pollen grain. This process frequently occurs in cities due to the high rate of air pollution that can alter the quality of pollen, affecting its biological functions. In this work, the effect of different environmental stress factors, mainly UV-B radiation and polluting gases (CO, NO2 and SO2), on the viability and maturity of the pollen of four ornamental tree-species present in the green infrastructure of Granada, namely Acer negundo, Carpinus betulus, Olea europaea and Cupressus spp. is analyzed. Differential staining techniques were used with fresh pollen collected in areas with different exposure to environmental stress to detect intact cell membranes (Trypan blue) and the state of maturity (Pyrogallol red). It was observed that the species from sectors more exposed to environmental stress registered a low viability and were affected by factors such as UV-B radiation and atmospheric pollutants. On the contrary, the pollen from tree species growing in peri-urban forests presented a higher rate of viability and less effect of pollutant factors. Differences were also observed according to the species/genus and according to the sampling area. This modification in the morphological and/or organic composition of the pollen wall may cause a loss of quality in the reproductive processes of plants, and it may be bioindicator of the process of progressive degradation that plant species can experience in urban environments under conditions of environmental stress, and prevent the impacts that can affect other species.

Published: December 2022

Habitats have been undergoing significant changes due to environmental processes and human impact that lead into habitat fragmentation and connectivity loss. To improve quality habitats and maintain ecological connectivity, elements that improve the connectivity of habitats need to be identified. To meet this goal, finding optimal pathways locations plays a key role for designing corridors for biodiversity conservation. Conducted in the Castilla y León region of Spain, this paper aims to determine optimal pathways and to enhance the connectivity of protected areas. To this end, three different scenarios were developed including the Natura 2000 network and their surroundings (Natura 2000, Level 0, and Level 1). We used Restoration Planner (RP) available in GuidosToolbox to analyze the network and detect pairwise optimum restoration pathways between the five largest network objects. Our results demonstrate that connector density varies across the region for each scenario. There was also a large variability in the length of connectors. Connectors were found mainly distributed around the center and northwestern part of Castilla y León. This paper also suggests that proposed new restoration pathways should increase in the study area. Thus, the findings can be used effectively for extensive planning and interpretation in biodiversity conservation.

Published: December 2022

To keep pace with the rapid advancements in molecular genetics and rare diseases research, we have updated the list of ectodermal dysplasias based on the latest classification approach that was adopted in 2017 by an international panel of experts. For this purpose, we searched the databases PubMed and OMIM for the term “ectodermal dysplasia”, referring mainly to changes in the last 5 years. We also tried to obtain information about those diseases on which the last scientific report appeared more than 15 years ago by contacting the authors of the most recent publication. A group of experts, composed of researchers who attended the 8th International Conference on Ectodermal Dysplasias and additional members of the previous classification panel, reviewed the proposed amendments and agreed on a final table listing all 49 currently known ectodermal dysplasias for which the molecular genetic basis has been clarified, including 15 new entities. A newly reported ectodermal dysplasia, linked to the gene LRP6, is described here in more detail. These ectodermal dysplasias, in the strict sense, should be distinguished from syndromes with features of ectodermal dysplasia that are related to genes extraneous to the currently known pathways involved in ectodermal development. The latter group consists of 34 syndromes which had been placed on the previous list of ectodermal dysplasias, but most if not all of them could actually be classified elsewhere. This update should streamline the classification of ectodermal dysplasias, provide guidance to the correct diagnosis of rare disease entities, and facilitate the identification of individuals who could benefit from novel treatment options.
Investigating the Diversity of Tuberculosis Spoligotypes with Dimensionality Reduction and Graph Theory
Authors: Senelle Gaetan , Guyeux Christophe , Refrégier Guislaine , Sola Christophe
Published: December 2022

The spoligotype is a graphical description of the CRISPR locus present in Mycobacterium tuberculosis, which has the particularity of having only 68 possible spacers. This spoligotype, which can be easily obtained either in vitro or in silico, allows to have a summary information of lineage or even antibiotic resistance (when known to be associated to a particular cluster) at a lower cost. The objective of this article is to show that this representation is richer than it seems, and that it is under-exploited until now. We first recall an original way to represent these spoligotypes as points in the plane, allowing to highlight possible sub-lineages, particularities in the animal strains, etc. This graphical representation shows clusters and a skeleton in the form of a graph, which led us to see these spoligotypes as vertices of an unconnected directed graph. In this paper, we therefore propose to exploit in detail the description of the variety of spoligotypes using a graph, and we show to what extent such a description can be informative.
Endoscopic Surveillance and Treatment of Upper GI Tract Lesions in Patients with Familial Adenomatous Polyposis—A New Perspective on an Old Disease
Authors: Paszkowski Jacek , Samborski Paweł , Kucharski Marcin , Cwaliński Jarosław , Banasiewicz Tomasz , Pławski Andrzej
Published: December 2022

Familial adenomatous polyposis (FAP) is an autosomal dominant disease caused by a germline mutation in the adenomatous polyposis coli (APC) gene. Patients with FAP develop up to thousands of colorectal adenomas as well as lesions in the upper GI tract. In FAP, the upper digestive lesions include gastric fundic gland polyps (FGPs), antrum adenomas, duodenal or small intestinal adenomas, and carcinoma. Patients, after colectomy, are still at significant risk for extracolonic malignancies. Advances in endoscope resolution and optical enhancement technologies allow endoscopists to provide assessments of benign and malignant polyps. For this reason, in the past decades, endoscopic resection techniques have become the first line of treatment in patients with polyps in the upper GI, whereby polyps and even early cancers can be successfully cured. In FAP patients, endoscopic ampullectomy appears to be a safe and effective way of treating patients with ampullary tumors. According to current indications, endoscopic retrograde cholangiopancreatography (ERCP) and stenting of the main pancreatic duct follow ampullectomy.
The Diverse Role of CUB and Sushi Multiple Domains 1 (CSMD1) in Human Diseases
Authors: Ermis Akyuz Esra , Bell Sandra M.
Published: December 2022

CUB and Sushi Multiple Domains 1 (CSMD1), a tumour suppressor gene, encodes a large membrane-bound protein including a single transmembrane domain. This transmembrane region has a potential tyrosine phosphorylation site, suggesting that CSMD1 is involved in controlling cellular functions. Although the specific mechanisms of action for CSMD1 have not yet been uncovered, it has been linked to a number of processes including development, complement control, neurodevelopment, and cancer progression. In this review, we summarise CSMD1 functions in the cellular processes involved in the complement system, metastasis, and Epithelial mesenchymal transition (EMT) and also in the diseases schizophrenia, Parkinson’s disease, and cancer. Clarifying the association between CSMD1 and the aforementioned diseases will contribute to the development of new diagnosis and treatment methods for these diseases. Recent studies in certain cancer types, e.g., gastric cancer, oesophageal cancer, and head and neck squamous cell carcinomas, have indicated the involvement of CSMD1 in response to immunotherapy.

Published: December 2022

Bacteriocins are gaining immense importance in therapeutics since they show significant antibacterial potential. This study reports the bacteriocin KAE01 from Enterococcus faecium, along with its characterization, molecular modeling, and antibacterial potency, by targeting the matrix protein of Pseudomonas aeruginosa. The bacteriocin was purified by using ammonium sulfate precipitation and fast protein liquid chromatography (FPLC), and its molecular weight was estimated as 55 kDa by means of SDS-PAGE. The bacteriocin was found to show stability in a wide range of pH values (2.0–10.0) and temperatures (100 °C for 1 h and 121 °C for 15 min). Antimicrobial screening of the purified peptide against different strains of P. aeruginosa showed its significant antibacterial potential. Scanning electron microscopy of bacteriocin-induced bacterial cultures revealed significant changes in the cellular morphology of the pathogens. In silico molecular modeling of KAE01, followed by molecular docking of the matrix protein (qSA) of P. aeruginosa and KAE01, supported the antibacterial potency and SEM findings of this study.

Published: December 2022

Background: Aortic root dilation (ARD) has been described in 22q11.2DS, even without congenital heart disease (CHD). However, the clinical implications and longitudinal course are unclear. In this study, we evaluated aortic root (AR) dimensions in 22q112.DS adolescents/adults without major intracardiac CHDs, analyzed the progression over time and investigated correlations with extracardiac comorbidities. Methods: AR dimensions were evaluated in 74 patients, measuring the sinus of Valsalva (VS) and proximal ascending aorta (AA), using Z-score to define mild, moderate and severe degrees. Changes in AR dimensions during longitudinal echocardiographic follow-up were investigated. Phenotypic characteristics have been collected. Results: Twenty-four patients (32.4%) showed ARD in terms of VS Z-score (2.43; IQR 2.08–3.01), eight (33.3%) of a moderate/severe degree. Thirteen (54.2%) had concomitant AAD (Z-score 2.34; IQR 1.60–2.85). The risk of ARD was significantly directly related to skeletal/connective tissue disorders (OR 12.82, 95% CI 1.43–115.31; p = 0.023) and inversely related to BMI (OR 0.86, 95% CI 0.77–0.97; p = 0.011). A significant increase in AR diameter’s absolute value (p = 0.001) over time has been detected. Conclusion: Isolated ARD is common in 22q11.2DS. Although some clinical risk factors have been identified, pathogenetic mechanisms and risk of complications are undefined. Regular cardiac evaluations should be part of the 22q11.2DS follow-up, and also in non-CHDs patients, to improve long-term outcome.

Published: December 2022

(1) Background: Rumors are a special type of information. Based on the classic theory of the communication of information, the “5W” communication model, this article aims to build a new model and thus explains the generation and communication of Internet health rumors. (2) Methods: The authors selected 50 Internet health rumors, which were widely spread in widely used websites and social media in China, then grounded theory is used to perform the qualitative analysis of the Internet health rumors. (3) Results: Three Core Concepts are abstracted after qualitative analysis. An internal dynamic mutual assistance mechanism of the communication of rumors is built and illustrated. Based on Lasswell’s “5W” communication model, the authors develop an eight-element communication model for Internet health rumors to illustrate the generation and communication of Internet health rumors. (4) Conclusions: By removing one or several elements of this new model, the chain of the communication of Internet health rumors could be cut off, which is valuable information for the government or websites to manage communication of Internet health rumors.
Linking Perceived Environmental CSR to Residents’ Environmental Citizenship Behavior in Rural Tourism: The Mediating Role of Resident–Environment Relationship Quality
Authors: Rao Xiaojuan , Qiu Hongliang , Morrison Alastair M. , Wei Wei
Published: December 2022

Residents’ environmental citizenship behavior is essential to the environmental protection and sustainable development of rural destinations. However, previous research with regards to environmental citizenship behavior has focused on an employee perspective, rather than a resident one. Through the theoretical lens of the Stimulus-Organism-Response (SOR) model, our research examined how perceived environmental CSR (ECSR) contributes to residents’ environmental citizenship behavior, with resident-environment relationship quality acting as the organism. Data collected from a Chinese rural destination were analyzed with a structural equation modeling approach. Results indicate that: (1) perceived ECSR directly and positively influences residents’ environmental citizenship behavior; (2) relationship quality variables (i.e., environmental identification and environmental commitment) directly and positively affect residents’ environmental citizenship behavior; (3) environmental identification directly and positively affects environmental commitment; (4) relationship quality variables positively mediate the effect of perceived ECSR on residents’ environmental citizenship behavior. The current research complements existing tourism literature on environmental citizenship behavior with a focus on perceived ECSR and relationship quality from the aspect of residents in rural destinations. The findings also provide some practical implications that potentially facilitate the adoption of environmental citizenship behavior among residents for sustainable destination management.

Published: December 2022

Topical anesthetics are commonly used to minimize pain and anxiety during dental procedures. Research is scarce on the influence of topical anesthetics on bond strength. Thus, this research evaluated the effect of dentin contamination by topical anesthetic solution and gel on the micro-shear bond strengths of etch-and-rinse and self-etch bonding systems. Ninety transversally hemi-sectioned dentin discs were prepared and randomly assigned to three groups: no contamination (control group), contamination with topical anesthetic solution (Xylonor spray, Septodont), and contamination with topical anesthetic gel (Xylonor gel, Septodont). Each contamination group was subdivided into two subgroups (n = 15) based on whether the adhesive system was etch-and-rinse (Optibond Solo Plus, Kerr) or self-etch (Optibond XTR, Kerr). Tygon tubes with resin composite (Filtek Z350 XT, 3M ESPE) were placed on each surface and light cured. After 24 h, a universal testing machine was used to measure micro-shear bond strength (MPa). Furthermore, nine additional specimens of non-contaminated and contaminated dentin were prepared and scanned by a scanning electron microscope. The data of micro-shear bond strength were analyzed using two-way ANOVA, and narrative analysis was used to qualitatively interpret visual data of the micro-morphology of dentin from the scanning electron microscope. No significant differences in micro-shear bond strength among different contamination groups and adhesive systems were found (p > 0.05). The results are supported by micro-morphology of the treated dentin surfaces and modes of failure, as the micro-morphology was similar among contamination and control groups. There was no significant impact of topical anesthetic forms and dentin bonding systems on the micro-shear bond strength, which was supported by the micro-morphology from a scanning electron microscope.
The Consequences of the Pandemic for Subjective Well-Being: Data for Improving Policymaking
Authors: Martínez Lina , Lora Eduardo , Espada Andres David
Published: December 2022

The pandemic has affected people’s lives and emotions in profound ways, which governments ignore at their peril. Among the often disregarded consequences of the pandemic, especially in developing countries, are its toll on subjective well-being and its implications for health policymaking. This paper uses a battery of surveys with over 1800 observations collected in 2019 and 2020, which inform on many aspects of subjective well-being before and during the pandemic in Cali, Colombia. The results show a dramatic and widespread reduction in life satisfaction in several dimensions of well-being beyond health, and not just among those directly affected by COVID-19. This analysis focuses on differences in well-being by gender and health status, providing information about gender variances and differences in subjective well-being between those who experienced and those who did not experience physical illness (including the COVID-19 infection) during the pandemic. This analysis aims at contributing to the body of research that studies the consequences of the pandemic for life satisfaction and well-being, in the context of a city experiencing profound social unrest during the pandemic.

Published: December 2022

Background: Data on the relation between non-emergency and emergency cardiac admission rates during the COVID-19 lockdown and post-lockdown period are sparse. Methods: Consecutive cardiac patients admitted to our tertiary heart center between 1 January and 30 June 2020 were included. The observation period of 6 months was analyzed in total and divided into three defined time periods: the pre-lockdown (1 January–19 March), lockdown (20 March–19 April), and post-lockdown (20 April–30 June) period. These were compared to the reference periods 2019 and 2022 using daily admission rates and incidence rate ratios (IRR). Results: Over the observation period from 1 January to 30 June, cardiac admissions (including non-emergency and emergency) were comparable between 2019, 2020, and 2022 (n = 2889, n = 2952, n = 2956; p = 0.845). However, when compared to the reference period 2019, non-emergency admissions decreased in 2020 (1364 vs. 1663; p = 0.02), while emergency admissions significantly increased (1588 vs. 1226; p < 0.001). Further analysis of the lockdown period revealed that non-emergency admissions dropped by 82% (IRR 0.18; 95%-CI 0.14–0.24; p < 0.001) and 42% fewer invasive cardiac interventions were performed (p < 0.001), whereas the post-lockdown period showed a 52% increase of emergency admissions (IRR 1.47; 95%-CI 1.31–1.65; p < 0.001) compared to 2019. Conclusions: We demonstrate a drastic surge of emergency cardiac admissions post-COVID-19 related lockdown suggesting that patients who did not keep their non-emergency appointment had to be admitted as an emergency later on.

Published: December 2022

A study on a single-leg landing task after an overhead stroke in badminton suggests that poor knee biomechanical indicators may be a risk factor for anterior cruciate ligament (ACL) injury. A preventive program targeting neuromuscular control strategies is said to alter the biomechanics of the knee joint and have a beneficial effect on reducing ACL injury. However, the relationship between muscle activity around the knee joint and knee biomechanical risk factors in the badminton landing task is unclear. The purpose of this study was to investigate the relationship between this movement pattern of muscle activity and knee kinematics and kinetics. This experiment analyzed knee muscle activity and biomechanical information in a sample of 34 badminton players (17 male, 17 female) during a badminton landing task. We assessed the relationship between the rectus femoris (RF), medial hamstring (MHAM), lateral hamstring (LHAM), medial gastrocnemius (MGAS), lateral gastrocnemius (LGAS), medial and lateral hamstring to quadriceps co-contraction ratio (MH/Q and LH/Q) with the knee flexion angle, valgus angle, extension moment, valgus moment, and proximal tibial anterior shear force. A moderate negative correlation was found between the peak knee flexion angle and electromyography (EMG) activity in LGAS (r = 0.47, p = 0.0046, R2 = 0.23, 95% CI: 0.16 to 0.70). Peak proximal tibial shear force showed strong and positive correlations with RF EMG activity (r = 0.52, p = 0.0016, R2 = 0.27, 95% CI: 0.22 to 0.73) and strong and negative correlations with MH/Q (r = 0.50, p = 0.0023, R2 = 0.25, 95% CI: 0.20 to 0.72). The knee extension moment showed moderate and positive correlations with RF EMG activity (r = 0.48, p = 0.0042, R2 = 0.23, 95% CI: 0.17 to 0.70) and strong and negative correlations with MH/Q (r = 0.57, p = 0.0004, R2 = 0.33, 95% CI: 0.29 to 0.76). The peak knee valgus moment showed strong and positive correlations with LH/Q (r = 0.55, p = 0.0007, R2 = 0.31, 95% CI: 0.26 to 0.75). Our findings suggest that there is a correlation between lower extremity muscle activity and knee kinematics and kinetics during the single-leg landing task in badminton; therefore, lower extremity muscle activity should be considered when developing rehabilitation or injury prevention programs.
Environmental Regulation, Scientific and Technological Innovation, and Industrial Structure Upgrading in the Yellow River Basin, China
Authors: Wang Jianshi , Cheng Yu , Wang Chengxin
Published: December 2022

Industrial structure upgrading is an important prerequisite for achieving regional ecological environment protection and high-quality development, and environmental regulation can improve the capacity of scientific and technological innovation and promote industrial structure transformation and upgrading. Based on the panel data of 78 cities in the Yellow River Basin, the relationships among environmental regulation, scientific and technological innovation, and industrial structure upgrading in the Yellow River Basin were analyzed using the mediating effect model and the panel threshold model. The results showed the following findings: (1) Although both formal and informal environmental regulations can promote industrial structure upgrading in the Yellow River Basin, regional heterogeneity and temporal stage characteristics are observed. (2) Transmission mechanism test results show that formal and informal environmental regulations directly affect industrial structure upgrading and indirectly act on it through the level of scientific and technological innovation, showing a significant mediating effect. (3) Taking scientific and technological innovation as the threshold variable, formal environmental regulations have a corresponding relationship with industrial structure upgrading in the form of a broken line, and informal environmental regulations significantly promote industrial structure upgrading after scientific and technological innovation crosses a certain threshold. Finally, we discuss the article and make corresponding suggestions in terms of environmental regulation and technological innovation.

Authors: Sims Stacy T. , Mackay Kelsi , Leabeater Alana , Clarke Anthea , Schofield Katherine , Driller Matthew
Published: December 2022

Background: While iron deficiency is commonly discussed in populations of professional female athletes, less is known about highly trained, sub-elite female athletes (e.g., those winning international age-group competitions) who generally have less access to medical and allied health support. Methods: Thirteen non-professional highly trained female endurance athletes provided training diaries and completed a blood test, where iron markers of haemoglobin (Hb), haematocrit (Hct), C-reactive protein (Crp), serum iron, serum ferritin, and transferrin were assessed. Resting metabolic rate (RMR) and body composition using dual-energy X-ray absorptiometry (DXA) were also obtained. Participants were classified as iron deficient (ID) if serum ferritin was <30 ug/L serum ferritin. Results: Six of the 13 females were classified as ID. Serum iron, ferritin, Hb, Hct, and ferrin were greater in the ID group (p < 0.05). Crp resulted in large to very large correlations with serum iron (r = −0.72), serum ferritin (r = −0.66), and transferrin (r = 0.70). Conclusions: In this population of highly trained female athletes, 46% were diagnosed with sub-optimal iron levels, which could have lasting health effects and impair athletic performance. The need for more education and support in non-professional athletes regarding iron deficiency is strongly advised.

The worldwide pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has impacted all healthcare systems. One potential sequela experienced by hospitalized coronavirus disease 2019 (COVID-19) survivors includes muscle weakness with a reduction in strength and, consequently, a possible increase in frailty. The aim of this clinical trial was to evaluate the efficacy of adding an online therapeutic exercise program for 8 weeks to the medical prescriptions on functional variables in patients hospitalized due to COVID-19. A randomized controlled trial including 70 previously hospitalized COVID-19 survivors was conducted. Patients were randomly allocated to an experimental (n = 35) or control (n = 35) group. Both groups received regular prescriptions provided by their medical doctors. The experimental group also received a live online therapeutic exercise program for 8 weeks (3 sessions/week). Handgrip strength, gait speed, lower-extremity strength, balance, and frailty were assessed at baseline, at the end of the program, and one month after the end of the intervention. The repeated measures analysis of variance revealed significant Group*Time interactions for all the outcomes: (handgrip dominant: F = 17.395, p < 0.001, η2 = 0.24; handgrip non-dominant: F = 33.197, p < 0.001, η2 = 0.33; 4 m walk test (4WT): F = 13.039, p = 0.001, η2 = 0.16; short physical performance battery (SPPB): F = 26.421, p < 0.001, η2 = 0.28; the five chair-raise test (5CRT): F = 5.628, p = 0.004, η2 = 0.08; FRAIL scale: F = 11.249, p = 0.001, η2 = 0.14): patients in the experimental group experienced greater improvements in all outcomes than those assigned to the control group. This study revealed that the addition of an online exercise program for 8 weeks obtained greater improvements in handgrip strength, gait speed, lower-extremity strength, balance, and frailty in a sample of previously hospitalized COVID-19 survivors than application of just usual medical prescription.

Published: December 2022

United States (U.S.) mariners continued sailing throughout COVID-19. Many aspects of their work could make them prone to adverse mental health outcomes but research on workplace determinants of their mental health during COVID-19 is limited. Between January and July 2021 an online survey assessed the outcomes of increased depressive symptoms, increased anxiety symptoms, and increased perceived stress in addition to concerns, worries, and experiences when sailing during COVID-19, job satisfaction, and safety climate in n = 1384 U.S. mariners. Demographic measures were also collected. Logistic regression models (for depression and anxiety) and a linear regression model (for stress) were developed. We found that increased COVID-19 concerns and poor self-reported mental health were related to increased odds of likely depression and anxiety and higher stress. Mariners who experienced more adverse experiences aboard a vessel had increased stress and increased odds of depression. Poor sleep quality was also related to increased odds of depression, and poor vessel support/safety culture was related to higher stress. Differences in outcomes were seen by vessel type, age, and credential in regression analyses. Results from this study will help to prioritize interventions to minimize the mental health impacts of COVID-19, and influence evidence-based recommendations to improve the mental health of mariners going forward.

Nursing homes for the elderly in Spain have experienced high rates of infection and mortality from COVID-19, although rates have varied from one region to another. Madrid is the region where most institutionalized older adults have died from the coronavirus. However, there is little known about the psychosocial and environmental factors involved in the high incidence of COVID-19 among the institutionalised population in this region. This article describes the protocol of a study on nursing homes during the SARS-CoV-2 pandemic in the Autonomous Community of Madrid (hereafter: Region of Madrid or Madrid Region) and provides information on the study design, measures used, and characteristics of the population studied. A questionnaire about life in nursing homes during the COVID-19 pandemic was designed and a total of 447 persons over 60 years of age without cognitive impairment—220 in private nursing homes and 227 in public nursing homes—participated by answering questions about different topics: personal situations during the pandemic, feelings and methods of coping, residential environment, health, quality of life, ageism, and self-perception of ageing. The institutionalised person profile discussed in this study was an old woman, widowed, without children, with a low level of education, with multimorbidity, and who perceived her health and quality of life positively. Most of the participants were very concerned about COVID-19 and its effects. In fact, 38% had been diagnosed with COVID-19, of whom 20% were admitted to hospital and 20% had suffered negative impacts, such as pain and neurological problems. In addition, 70% of the residents remained confined to their rooms, which increased their perceptions of loneliness and social isolation. The worst-rated aspects of the nursing home resulted from the restrictive measures imposed on nursing homes during the pandemic. This research offers useful material for understanding the pandemic and its consequences from the perspective of the older institutionalised population, which could provide insights for designing public policies.

Published: December 2022

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection has been associated with greater morbidity and increased mortality in certain populations, such as those with chronic medical conditions, the elderly, and pregnant women. Our goal was to determine if COVID-19 infection during pregnancy increased the risk of preeclampsia in a population of women with increased risk factors for preeclampsia. We present a prospective observational matched case–control study of 100 deliveries with confirmed SARS-CoV2. Specifically, we investigated the maternal and neonatal outcomes in a high-risk population of pregnant women. Among women with COVID-19, the severity of symptoms was associated with the incidence of preeclampsia, but not with pre-existing diabetes or hypertension. Women with more severe symptoms were more likely to delivery pre-term with smaller babies. After adjusting for diabetes, hypertensive women with COVID-19 had an increased risk of preeclampsia aOR4.3 [1.5,12.4] compared to non-hypertensive women with COVID-19. After adjusting for hypertension, women with diabetes and COVID-19 had an increased risk of preeclampsia aOR3.9 [1.2,12.5]. This relationship was not seen among women without COVID-19. For women who had pre-existing diabetes or hypertension, the risk of developing preeclampsia was only increased if they were also diagnosed with COVID-19, suggesting that in our population of women the risk of preeclampsia is not associated with pre-existing diabetes or hypertension.

Published: December 2022

Various studies have indicated that persons with special needs may face several barriers to dental treatment, which increases the prevalence of oral diseases in this population. Moreover, these studies suggested that Saudis with special needs have a higher prevalence of oral diseases, such as dental caries and periodontal disease. The aim of this review is to synthesize evidence regarding the current status, trends in oral health behaviors, and oral health care utilization among these individuals, as well as to assess the quality of the literature. Furthermore, this review seeks to recommend directions for future research and oral health care policymaking. An electronic search was conducted using the following databases and registers: PubMed/Medline, Embase, ISI Web of Science, Scopus, ClinicalTrials.gov, and CENTRAL. Gray literature, which included conference proceedings and unpublished literature, was searched via the library services and Google/Google Scholar, and the quality of studies was assessed using the AXIS scale for cross-sectional studies. A total of 38 studies were included in this review, with the majority of the studies graded as ‘low’. Within the limitations of this study, it can be concluded that individuals with special needs have limited access to oral health care, poor oral health status, and a general lack of awareness in regard to oral health. Therefore, nationwide surveys should be carried out to ascertain the actual extent of the oral inequities among individuals with special needs.

Published: December 2022

It is very necessary to study the mechanism of rock burst, which is related to the safe construction of many geotechnical projects. Previous studies have shown that small trigger stress will lead to large energy release, but the specific conditions that cause the release and how to quantify the energy are urgent problems to be solved. In this study, an innovative calculation method of rock mass energy release is proposed, and the calculated release energy is consistent with the monitoring results of field monitoring equipment. The revealed mechanism of rock burst reflected is that under the condition of a large-ratio pre-state stress field (mostly > 2.5), a small trigger stress field will lead to a large amount of energy release under “late butterfly shape” or “final butterfly shape” of the plastic zone. This study reveals the key factor of rock burst, which plays an important reference role for the mechanism research, subsequent monitoring and treatment method of rock burst.

With increasing water resources stress under climate change, it is of great importance to deeply understand the spatio-temporal variation of crop water requirements and their response to climate change for achieving better water resources management and grain production. However, the quantitative evaluation of climate change impacts on crop water requirements and the identification of determining factors should be further explored to reveal the influencing mechanism and actual effects thoroughly. In this study, the water requirements of winter wheat and summer maize from 1981 to 2019 in the lower reaches of the Yellow River Basin were estimated based on the Penman–Monteith model and crop coefficient method using daily meteorological data. Combined with trends test, sensitivity and contribution analysis, the impacts of different meteorological factors on crop water requirement variation were explored, and the dominant factors were then identified. The results indicated that the temperature increased significantly (a significance level of 0.05 was considered), whereas the sunshine duration, relative humidity and wind speed decreased significantly from 1981 to 2019 in the study area. The total water requirements of winter wheat and summer maize presented a significant decreasing trend (−1.36 mm/a) from 1981 to 2019 with a multi-year average value of 936.7 mm. The crop water requirements of winter wheat was higher than that of summer maize, with multi-year average values of 546.6 mm and 390.1 mm, respectively. In terms of spatial distribution patterns, the crop water requirement in the north was generally higher than that in the south. The water requirements of winter wheat and summer maize were most sensitive to wind speed, and were less sensitive to the minimum temperature and relative humidity. Wind speed was the leading factor of crop water requirement variation with the highest contribution rate of 116.26% among the considered meteorological factors. The results of this study will provide important support for strengthening the capacity to cope with climate change and realizing sustainable utilization of agricultural water resources in the lower reaches of the Yellow River Basin.
Decision-Making concerning Involuntary Oral Care for Older Individuals with Dementia

Many older individuals with dementia (OIWD) show care-resistant behavior for oral care. Providing care despite resistance is considered to be involuntary care. Although involuntary care should be minimized, in some OIWD it may be necessary to avoid health risks. This study aims to assess the attitudes of healthcare providers with regard to involuntary oral care provision for OIWD who show care-resistant behavior. An online questionnaire consisting of general questions and case specific questions was administered via social media and networking to individuals involved in the oral care of OIWD. A total of 309 participants were included in this study. The outcomes of the questionnaires were categorized per case. In all cases, a discrepancy was seen between the assessment of oral health problems as potentially harmful (range: 73.1–93.5%) and the willingness to provide involuntary care (range: 31.1–63.4%). Hence, many healthcare providers are aware of the subsequent potential health risks related to not providing care, but are still reluctant to provide involuntary oral care. Therefore, many OIWD who show care-resistant behavior potentially do not receive the necessary oral care they require.
Social Values of Care Robots

Care robots have the potential to address the challenge of aging societies, such as labor shortages or the aging workforce. While previous studies have focused mainly on the productivity or workability of care robots, there has been an increasing need to understand the social value of care robots. This study attempted to identify the social values of care robots by conducting focus group interviews (FGIs) with twenty-four care recipients and caregivers and by using analytic hierarchy processes (AHPs) with thirteen individuals with expertise in the care service and care robot industries. Our results show that the labor- and health-related benefits, the technology innovation, and the provision of essential care work have the highest importance among the criteria of care robots’ social values. The criteria that receive lowest priority are cost, the autonomy and needs of the care recipients, and the organizational innovation. Our study suggests that along with the private benefits and costs of care robots, their social values also need to be considered to improve the quality of care and to unlock the potential of the care robot industries.

Published: December 2022

COVID-19 has generated an uncertain environment, which has motivated changes in consumers’ behavior globally. However, previous studies have not clarified if these effects are equally strong throughout the population. In this research, we want to analyze if there are behavioral differences between long-COVID consumers and others. For this purpose, we analyzed a sample of 522 consumers divided into three groups depending on their type of exposure to the disease: those with long COVID; ones that had recovered from COVID-19; and those that had never had COVID-19. The results show that the effect that COVID-19 has on purchase behavior differs depending on the type of exposure to the disease. In fact, those with long COVID experienced more pleasure when purchasing than other people, but they needed higher trust levels in the enterprises to purchase from them, since that reduces their perception of uncertainty. Furthermore, for long-COVID individuals, an organization’s legitimacy level is even more important than for other consumer groups with less contact with the disease.

Published: December 2022

The purpose of this article is to understand the experience of workers’ perceptions of job insecurity and its relation to performance. To this end, we conducted semi-structured interviews with 38 workers in the retail, services, education, financial, construction, and pharmaceutical industries in Chile. Using content analysis based on workers’ accounts of their own experience, we identified two main categories: (a) the experience of job insecurity viewed in relation to the context of the COVID-19 pandemic and emotional aspects of job insecurity, and (b) the relation between job insecurity and performance. The possibility of job loss expresses itself in experiences and emotions that are related to the performance of workers in different ways. These findings are discussed in terms of stress theory and the motivation to preserve jobs.

Widespread dissemination of misinformation about climate change has seriously harmed the health of future generations and the world. Moreover, misinformation-sharing behaviors exhibit strong individual characteristics. However, research is limited on the antecedents of and mechanism underlying the willingness to share misinformation about climate change in terms of individual personalities and physiological states. Accordingly, we surveyed 582 women (224 pregnant) using a questionnaire and constructed a moderated mediation model to explore the relationships among individuals’ bullshit receptivity, belief in misinformation about climate change, willingness to share misinformation about climate change, and pregnancy. The results showed that: (1) bullshit receptivity is positively related to the willingness to share misinformation about climate change; (2) belief in misinformation about climate change mediates the relationship between bullshit receptivity and willingness to share misinformation about climate change; and (3) for individuals with higher bullshit receptivity, pregnancy exacerbates the detrimental effects of bullshit receptivity on belief in misinformation about climate change.
