RESUMO

OBJECTIVE: Caregiver contribution (CC) is important for the self-care behaviors of chronic disease individuals, as it could enhance patient outcomes. Therefore, it is necessary to assess this CC by using a good validity and reliability instrument. The Caregiver Contribution to Self-Care Chronic Illness Inventory (CC-SC-CII) was designed to assess CC to self-care behaviors of patients with chronic illness in Italy. However, it was unclear whether this tool had sound psychometrics properties in the context of Chinese culture. Therefore, we performed the cross-cultural adaption of the CC-SC-CII and we tested its psychometric properties among Chinese caregivers of patients with chronic disease. DESIGN: A cross-sectional observational design. SETTINGS: Participants were recruited from communities and institutions in Pingdingshan, Henan Province, China. PARTICIPANTS: 301 caregivers of care recipients with chronic disease completed the Chinese version of the CC-SC-CII (C-CC-SC-CII). PRIMARY AND SECONDARY OUTCOME MEASURES: The content validity index of items (I-CVI), the scale content validity index-average (S-CVI/Ave), exploratory factor analysis, confirmatory factor analysis (CFA), internal consistency and item analysis were tested. RESULTS: The range of I-CVI was between 0.833 and 1.00, and the score of S-CVI was 0.991. In CFA, the C-CC to self-care monitoring scale had satisfactory fit indices. However, the C-CC to self-care maintenance and management scales had unsupported fit indices. The reliability coefficients of C-CC-SC-CII were 0.792, 0.880 and 0.870 for its three scales. Item-total correlations were all over 0.590. Test-retest reliability showed that the range of intraclass correlation coefficients was from 0.728 to 0.783. CONCLUSION: The C-CC-SC-CII has sound psychometrics characteristics and is a culturally appropriate and reliable instrument for assessing CC to the self-care behaviours of patients with chronic disease in China.

RESUMO

Cadmium (Cd) and arsenic (As) contamination in paddy soils poses serious health risks to humans. The accumulation of Cd and As in rice (Oryza sativa L.) depends on their bioavailability, which is affected by soil physicochemical properties and soil microbial activities. However, little is known about the intricate interplay between rice plants and their rhizosphere microbes during the uptake of Cd and As. In this study, different bacterial communities were established by sterilizing paddy soils with γ-radiation. A pot experiment using two paddy soils with different levels of contamination was conducted to explore how the bacterial community composition affects Cd and As accumulation in rice plants. The results showed that the sterilization treatment substantially changed the bacterial composition in the rhizosphere, and significantly increased the grain yield (by 33.5-38.3%). The sterilization treatment resulted in significantly decreased concentrations of Cd (by 18.2-38.7%) and As (by 20.3-36.7%) in the grain, straw, and root of rice plants. The accumulation of Cd and As in rice plants was negatively correlated with the relative abundance of sulfate-reducing bacteria and iron-oxidizing bacteria in the rhizosphere. Other specific taxa associated with the accumulation of Cd and As in rice plants were also identified. Our results suggest that regulating the composition of the rhizosphere bacterial community could simultaneously reduce Cd and As accumulation in rice grain and increase the grain yield. These results would be useful for developing strategies to cultivate safe rice crops in areas contaminated with Cd and As.

RESUMO

OBJECTIVES: Patients living with cardiovascular diseases use different strategies to solve various problems. This study aimed to identify the category, type and specific self-management strategies reported by hospitalized patients with cardiovascular diseases. METHODS: This is a qualitative descriptive study. Twenty-eight individuals with cardiovascular diseases from a Cardiology Department affiliated with a school in China were recruited by purposive sampling. Face-to-face semi-structured interviews were used. The interviews were audio-recorded, transcribed, translated and analysed by using content analysis. RESULTS: Five self-management strategy categories (medical and alternative therapy uptake, risk assessment and avoidance, resource seeking and utilization, maintaining normality, and optional management), and seventeen self-management strategy types, encompassing one hundred and ten specific strategies were identified. The most commonly used self-management strategy types were lifestyle adjustment (eleven strategies), self-maintenance (nine strategies) and problem-solving (nine strategies). Additionally, the most described explicit self-management strategies were receiving family/colleague support, maintaining daily routines, monitoring symptoms and managing side effects, discussing with professionals, using medicines, and improving awareness. CONCLUSION: This study identified diverse strategies reported by some Chinese cardiovascular patients. It may inform the design and development of personalized self-management interventions for health practitioners and policymakers, helping cardiovascular patients in Chinese communities worldwide receive culture-tailored services.

RESUMO

AIM: To analyse the application status of nursing assessment terminology for neurological conditions and determine whether the International Classification of Functioning, Disability, and Health (ICF) covers nursing assessment. DESIGN: A multi-centre cross-sectional study. METHODS: Four researchers extracted all nursing problems from the patients of three different hospitals and formed a pool of nursing terminology from the electronic nursing records, self-reports, family reports, medical examinations, and clinical records for all patients. The ICF Linking Rules were then used to map the nursing assessment terminology of neurological conditions with the ICF. RESULTS: Though 37.5% of nursing assessment terms were closely related to neurological diseases, this does not appear in the existing electronic nursing assessment records. The unrecorded rate of 9 (16.1%) terms ranged from 40%-50%, while the unrecorded rate of 8 (14.3%) terms was more than 80%. Overall, 96.4% of nursing assessment terms could be described by the corresponding categories of the ICF, with 37 (66.1%) of the "same" concepts, 9 (16.1%) "similar" concepts, 6 (10.7%) "narrower" concepts (the nursing assessment terms were more specific than the ICF categories), and 2 (3.6%) "broader" concepts (the nursing assessment were less specific than the ICF categories).

RESUMO

AIMS : Lifestyle factors have been well-established as essential targets for fighting individual chronic diseases, but little research has concentrated on multimorbidity from the perspective of multiple lifestyle factors in the Chinese population. Thus, this study aimed to explore the associations of lifestyle factors with the occurrence of multimorbidity. METHODS AND RESULTS : Cross-sectional data retrieved from the China Health and Retirement Longitudinal Study were used for analysis. Multimorbidity was calculated on a simple count of self-reported chronic conditions. Lifestyle factors included sleep duration, physical activity, alcohol intake, smoking status, and body mass index. Logistic regression analysis was used to examine the independent and accumulating effects of lifestyle factors on multimorbidity. Latent class analysis was performed to explore the lifestyle patterns. Six thousand, five hundred, and ninety-one valid subjects were included for analysis. Overall, the community dweller's median number of chronic conditions was 1 (range 1-11) and median number of high-risk lifestyle factors was 2 (range 0-5). All lifestyle factors were associated with the occurrence of multimorbidity but varied between genders. We also identified that participants who accumulated more unhealthy lifestyle factors having a higher likelihood of multimorbidity. 'Physical activity and weight', 'smoke and drink', and 'sleep and weight' dominated high-risk lifestyles were the most common lifestyle patterns. CONCLUSION : This study revealed the associations of unhealthy lifestyle factors and their accumulating effect with multimorbidity in Chinese community dwellers. Three common lifestyle patterns indicated that a holistic approach focused on engaging and changing multiple modifiable lifestyle behaviours within an individual might be more effective in managing multimorbidity.

RESUMO

OBJECTIVE: Inflammation has been suggested to play an important role in the development and progression of metabolic syndrome (MetS). Dietary inflammatory index (DII), a measurement of inflammatory potential in diets, was suggested to be associated with MetS. The aim of this systematic review and meta-analysis was to establish the associations of DII with MetS and its components based on available observational studies. DESIGN: Systematic review and meta-analysis. SETTING: A comprehensive literature search of studies that assessed the associations between DII and MetS was conducted in PubMed, Medline and Embase, using a combination of search terms relating to DII and MetS. PARTICIPANTS: Eighteen articles were eligible, of which fourteen were cross-sectional and four were cohort in design. RESULTS: Results from the random effects meta-analysis showed significantly positive associations of higher DII (top v. bottom quartiles) with MetS (OR: 1·23 (95 % CI 1·10, 1·37)), abdominal obesity (OR: 1·15 (95 % CI 1·02, 1·29)), high blood pressure (OR: 1·17 (95 % CI 1·07, 1·29)), hyperglycaemia (OR: 1·18 (95 % CI 1·05, 1·33)) and hypertriacylglycerolaemia (OR: 1·17 (95 % CI 1·07, 1·28)). The effects of summary OR became stronger when analyses were restricted to cohorts, studies that adjudged for covariates (including BMI, physical activity and total energy intake). CONCLUSIONS: Higher DII, representing pro-inflammatory diet, is associated with higher odds of MetS and its components, except for low HDL-cholesterol. The findings prompt dietary interventions for preventing MetS from the aspect of inflammation.

RESUMO

One of the main challenges of electrochemical Fenton-based processes is the treatment of organic pollutants at near-neutral pH. As a potential approach to this problem, this work addresses the use of a low content of soluble chelated metal catalyst, formed between Fe(III) and ethylenediamine-N,N'-disuccinic (EDDS) acid (1:1), to degrade the herbicide triclopyr in 0.050 M Na2SO4 solutions at pH 7.0 by photoelectro-Fenton with UVA light or sunlight (PEF and SPEF, respectively). Comparison with electro-Fenton treatments revealed the crucial role of the photo-Fenton-like reaction, since this promoted the production of soluble Fe(II) that enhanced the pesticide removal. Hydroxyl radicals formed at the anode surface and in the bulk were the main oxidants. A boron-doped diamond (BDD) anode yielded a greater mineralization than an IrO2-based one, at the expense of reduced cost-effectiveness. The effect of catalyst concentration and current density on the performance of PEF with BDD was examined. The PEF trials in 0.25 mM Na2SO4 + 0.35 mM NaCl medium showed a large influence of generated active chlorine as oxidant, being IrO2 more suitable than RuO2 and BDD. In SPEF with BDD, the higher light intensity from solar photons accelerated the removal of the catalyst and triclopyr, with small effect on mineralization. A plausible route for the herbicide degradation by Fe(III)-EDDS-catalyzed PEF and SPEF is finally proposed based on detected byproducts: three heteroaromatic and four linear N-aliphatic compounds, formamide, and tartronic and oxamic acids.

RESUMO

Objectives: To examine the effects of the Roy Adaptation Model-based interventions on adaptation in persons with heart failure. Methods: A quasi-experimental study was conducted in Hangzhou, China, from March 2018 to November 2019. A convenience sample of 112 participants with heart failure from a multi-campus hospital was enrolled. Participants were allocated into an intervention group (n = 55) and a control group (n = 57) according to their hospitalized campus. A culturally-tailored care plan intervention based on the Roy Adaptation Model was performed in the intervention group. The control group received bedside patient education and a regular booklet for HF home care before discharge. Heart ultrasound, Minnesota Living with Heart Failure Questionnaire (MLHFQ), a knowledge survey, Self-care Heart failure Index (SCHFI), and Coping and Adaptation Processing Scale-Short Form (CAPS-SF) were used to measure patients' levels of adaptation of physical function, self-concept, role function, and interdependence at baseline and six months after discharge. Results: Ninety-one participants with complete data, 43 in the intervention group and 48 in the control group, were included in the analysis for the primary endpoints and showed adaptive improvement trends. Most patients in the intervention group completed 60% or more of the given interventions. At the sixth month after discharge, compared with the control group, the intervention group had improved adaptive behaviors showing higher scores of the MLHFQ (70.90 ± 22.45 vs. 54.78 ± 18.04), heart failure-related knowledge (13.79 ± 2.45 vs. 10.73 ± 4.28), SCHFI maintenance (57.67 ± 13.22 vs. 50.35 ± 10.88), and CAPS-SF (40.23 ± 4.36 vs. 38.27 ± 2.60) at the six-month follow-up (P < 0.05). There were no significant differences between the two groups in the scores of left ventricular ejection fraction, scores of SCHFI management and SCHFI confidence subscales (P > 0.05). Conclusions: The findings reported evidence of positive adaptation in patients with heart failure, indicating that the Roy Adaptation Model is an effective guide for developing an implemented framework for the nursing practice of the patients. The culturally-tailored care plan intervention is helpful to improve adaptation of patients with heart failure.

RESUMO

OBJECTIVE: We aimed to examine whether eHealth interventions can effectively improve anthropometric and biochemical indicators of patients with metabolic syndrome (MetS). DESIGN: Systematic review and meta-analysis. METHODS: PubMed, the Web of Science, Embase, Medline, CINAHL, PsycINFO, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Wanfang and Weipu databases were comprehensively searched for papers that were published from database inception to May 2019. Articles were included if the participants were metabolic syndrome (MetS) patients, the participants received eHealth interventions, the participants in the control group received usual care or were wait listed, the outcomes included anthropometric and biochemical indicators of MetS, and the study was a randomised controlled trial (RCT) or a controlled clinical trial (CCT). The Quality Assessment Tool for Quantitative Studies was used to assess the methodological quality of the included articles. The meta-analysis was conducted using Review Manager V.5.3 software. RESULTS: In our review, seven RCTs and two CCTs comprising 935 MetS participants met the inclusion criteria. The results of the meta-analysis revealed that eHealth interventions resulted in significant improvements in body mass index (standardised mean difference (SMD)=-0.36, 95% CI (-0.61 to -0.10), p<0.01), waist circumference (SMD=-0.47, 95% CI (-0.84 to -0.09), p=0.01) and systolic blood pressure(SMD=-0.35, 95% CI (-0.66 to -0.04), p=0.03) compared with the respective outcomes associated with the usual care or wait-listed groups. Based on the included studies, we found significant effects of the eHealth interventions on body weight. However, we did not find significant positive effects of the eHealth interventions on other metabolic parameters. CONCLUSIONS: The results indicated that eHealth interventions were beneficial for improving specific anthropometric outcomes, but did not affect biochemical indicators of MetS. Therefore, whether researchers adopt eHealth interventions should be based on the purpose of the study. More rigorous studies are needed to confirm these findings.

RESUMO

Purpose: This study aimed to investigate the status of cardiac rehabilitation knowledge and attitude of the medical staff. Patients and Methods: A questionnaire survey of doctors and nurses was performed in the departments of cardiology of 7 teaching hospitals with attitudes, knowledge toward CR in Zhejiang Province, China, from April to September 2018, to assess Chinese medical staff for the degree of mastery and attitude toward cardiac rehabilitation. Results: A total of 160 questionnaires were distributed and 152 valid were collected. The responding individuals included 106 nurses (69.74%) and 46 doctors (30.26%). The scores of cardiac rehabilitation knowledge were 56.68±5.06, and those of cardiac rehabilitation attitude were 15.19±3.86. Subgroup analysis showed the lower the job title (P<0.001), the lower the educational level (P = 0.011), and the shorter the years of specialty experience (P=0.005), the more negative the attitude toward cardiac rehabilitation. Conclusion: The medical staff has a good mastery of cardiac rehabilitation knowledge. But we also find that staffs with lower education level and job title, shorter specialty work experience were associated with a more negative attitude toward implement rehabilitation.

RESUMO

OBJECTIVES: High levels of organisational citizenship behaviour can enable nurses to cooperate with coworkers effectively to provide a high quality of nursing care during the outbreak of COVID-19. However, the association between autonomy, optimism, work engagement and organisational citizenship behaviour remains largely unexplored. This study aimed to test if the effect of autonomy on organisational citizenship behaviour through the mediating effects of optimism and work engagement. STUDY DESIGN: This was a cross-sectional study. SETTING: The study was conducted in the Wuhan Jinyintan Hospital in China. PARTICIPANTS: In total, 242 nurses who came from multiple areas of China to work at the Wuhan Jinyintan hospital during the COVID-19 epidemic participated in this study. METHODS: A serial mediation model (model 6) of the PROCESS macro in SPSS was adopted to test the hypotheses, and a 95% CI for the indirect effects was constructed by using Bootstrapping. RESULTS: The autonomy-organisational citizenship behaviour relationship was mediated by optimism and work engagement, respectively. In addition, optimism and work engagement mediated this relationship serially. CONCLUSION: The findings of this study may have implications for improving organisational citizenship behaviour. The effects of optimism and work engagement suggest a potential mechanism of action for the autonomy-organisational citizenship behaviour linkage. A multifaceted intervention targeting organisational citizenship behaviour through optimism and work engagement may help improve the quality of nursing care among nurses supporting patients with COVID-19.

RESUMO

OBJECTIVE: Close contacts of novel coronavirus disease 2019 (COVID-19) patients may suffer from physical and psychological problems. Few studies have investigated the quarantine experiences of close contacts of COVID-19 patients. The objective of this study was to best capture participants' quarantine experiences during the COVID-19 outbreak in China. METHODS: A descriptive, qualitative design was used. All interviews were recorded and coded using thematic analysis. RESULTS: Fifteen participants took part in this study. The following five themes emerged: (1) experience in the early stage of quarantine; (2) experience in the middle stage of quarantine; (3) experience in the late stage of quarantine; (4) self-coping persisted throughout the quarantine period; and (5) external support was evident throughout the quarantine period. CONCLUSION: Our study highlights the need to assess the psychological state of close contacts in the early stage of quarantine and to provide psychological support for them, especially for the older and the less educated. Although close contacts had physical symptoms and psychological issues, they adopted positive coping strategies, which indicated that they were vulnerable but strong. Furthermore, external support from the Chinese government helped them cope with the quarantine effectively. Learning from the quarantine experience is expected to help the Chinese government and institutions from other parts of the world to better care for close contacts.

RESUMO

Background: Adaptive capacity may serve as an indicator of the individuals' coping behaviors toward illness management and may contribute to day-to-day living with chronic illness and improved quality of life. Practical and well-constructed instruments for measuring adaptation have not been adequately explored. An English 15-item Coping and Adaptation Processing-Short Form (CAPS-SF) for assessing adaptation has been created and validated in line with the underlying tenets of Coping and Adaptation Processing theory, but there is no applicable Chinese version. Methods: The CAPS-SF was translated and culturally adapted into simplified Chinese. Among Chinese adults with chronic illness, 81 patients were selected for cultural adaptation and 288 patients were approached for psychometric testing. Content validity was evaluated by an expert panel. Construct validity was tested by confirmatory factor analysis. Concurrent validity and predictive validity were analyzed by Spearman correlation coefficient. Reliability was assessed by internal consistency and test-retest coefficients. Floor/ceiling effect was calculated. Results: Adequate content validity was ensured by the expert panel. A four-factor structure (resourceful and focused, self-initiated and knowing-based, physical and fixed, and positive and systematic) describing individuals' coping strategies was identified and verified. Concurrent validity and predictive validity were demonstrated by strong correlations with the confrontation of coping mode (r = 0.46) and a quality-of-life measure (r = 0.58). The McDonald's omega coefficient of total scale was 0.82. Split-half reliability and test-retest reliability were 0.87 and 0.87. No floor/ceiling effect was present. Conclusion: The Chinese version CAPS-SF is a theoretically based and culturally acceptable instrument with sound psychometric properties. Further studies are advocated to refine its four-factor structure.

RESUMO

This work reports the novel application of an Fe-based 2D metal-organic framework (MOF), prepared with 2,2'-bipyridine-5,5'-dicarboxylate (bpydc) as organic linker, as highly active catalyst for heterogeneous photoelectro-Fenton (PEF) treatment of the lipid regulator bezafibrate in a model matrix and urban wastewater. Well-dispersed 2D structures were successfully synthesized and their morphological, physicochemical and photocatalytic properties were assessed. UV/Vis PEF using an IrO2/air-diffusion cell with an extremely low catalyst concentration (0.05 g L-1, tenfold lower than reported 3D MOFs) outperformed electro-oxidation with electrogenerated H2O2, electro-Fenton and visible-light PEF. Its excellent performance was explained by: (i) the enhanced mass transport of H2O2 (and organic molecules) at the 2D structure, providing active sites for heterogeneous Fenton's reaction and in-situ Fe(II) regeneration; (ii) the ability of photoinduced electrons to reduce H2O2 to •OH, and Fe(III) to Fe(II); and (iii) the enhanced charge transfer and excitation of Fe-O clusters, which increased the number of electron-hole pairs. LC-QToF-MS and GC-MS allowed the identification of 16 aromatic products of bezafibrate. The complete removal of four micropollutants mixed in urban wastewater at pH 7.4 revealed the great potential of (Fe-bpydc)-catalyzed PEF process.

RESUMO

Owing to its sustainability and low cost, direct revegetation (DR) has been considered a promising alternative to capped revegetation (CR) for dealing with the serious environmental problem derived from various types of mine wastelands that are widespread in the world. However, a direct comparison of the performance of these two revegetation approaches for reclamation of extremely acidic mine wastelands and the underlying mechanisms is still lacking. To bridge this critical knowledge gap, we established 5000 m2 of vegetation on a highly acidified (pH < 3) Pb/Zn mine tailings pond employing both CR and DR schemes (2500 m2 for each scheme). We then profiled the structure, ecological network and function of soil microbial communities associated with two dominant plant species of the vegetations via high-throughput sequencing. Our results showed that CR and DR achieved a vegetation coverage of 59.7% and 90.5% within two years, respectively. This pattern was accompanied by higher concentrations of plant nutrients and lower acidification potentials in topsoils of the rhizospheres of the vegetation established by DR compared to those of CR. Revegetation approach, rather than plant identity, mostly affected the structure, ecological network and function of soil microbial community in the mine tailings pond. Rhizosphere soils of the vegetation established by DR generally had higher microbial diversity, higher relative abundances of dominant microbial phyla (e.g. Nitrospirae) that can aid plant uptake of nutrients, more complicated microbial interactive networks and more microbial genes responsible for nutrient cycling than those by CR. As the first report on a direct comparison of CR and DR schemes for reclamation of an extremely acidic mine wasteland, our study has important implications for not only the understanding of microbial ecology in revegetated mine wastelands but also the further development of sustainable revegetation schemes.

RESUMO

Purpose: This study aimed to translate the Roy adaptation model concept of adaptation level into measurable concepts when considering the health-related quality of life, social support, and self-efficacy of community-dwelling Chinese adults with metabolic syndrome. Patients and Methods: This was a descriptive cross-sectional study. Data were collected from 144 adults with metabolic syndrome in the suburban area of Hangzhou, China. Correlation analysis was performed to examine the relationships between environmental stimuli (sociodemographic characteristics), adaptation level (health-related quality of life and social support), and prerequisite of behavior (self-efficacy). Regression analysis was applied to test the effect of stimuli on adaptation level and their associations with behavior. Results: Adaptation level was potentially influenced by environmental stimuli and evaluated by the quality of life. Age and education level were related to physiological and psychological function. Besides, family income was related to physiological function. Thus, adaptation level may predict individuals' behavior towards illness management, with a percentage classification accuracy of 76.40%. The vitality and social functioning of the quality of life were identified as significant correlates of self-efficacy. Conclusion: Our findings demonstrate that individuals' internal and external resources should be considered when developing nursing interventions to improve patients' adaptation level. Future research should explore whether facilitating self-efficacy among community-dwelling adults with metabolic syndrome may positively influence an individual's adaptation process in health management.

RESUMO

INTRODUCTION: The Roy adaptation model provides a basis for developing the science of nursing. Its theoretical assumptions have been tested in empirical studies. Although several works have historically reviewed the development of this model, a refinement of its key concepts is needed. The proposed scoping review aims to describe how the concept of adaptation was defined and measured in nursing studies related to chronic health conditions. METHODS AND ANALYSIS: This scoping review will adopt the methodology proposed by Arksey and O'Malley. Several databases, including MEDLINE (OVID), CINAHL, EMBASE, PsycINFO, PubMed, Wan Fang, China National Knowledge Infrastructure and VIP net, will be selected and used to mine literature published in English and Chinese languages, up to December 2019. Key terms related to 'Roy adaptation model' will be identified and used for developing tailored search strategies for each database. Articles will be included in the analysis if they are primary research reports explaining the concept of adaptation within the field of chronic care. All screening and extraction of literature will be independently performed and checked by two authors, according to the guideline of Preferred Reporting Items for Systematic Review and Meta-Analysis-Extension for Scoping Reviews. The findings will be organised and summarised into narratives in line with the construction of conceptual-theoretical-empirical system of knowledge for further consultation and translation. ETHICS AND DISSEMINATION: This scoping review does not require ethical approval. The findings are expected to be published in peer-reviewed English or Chinese journals as well as conference proceedings in the area of chronic care.

RESUMO

BACKGROUND: Limited work has been done to explain how work-family conflict is related to anxiety symptoms and the roles of emotional exhaustion and social support may play. METHODS: Based on a sample of 764 female nurses and physicians, a model was tested in which emotional exhaustion served as a mediator and social support was regarded as a moderator between work-family conflict and anxiety symptoms. RESULTS: This current study supported a moderated mediation model where the relationship between work-family conflict and anxiety symptoms via emotional exhaustion was weakest for female medical staff who reported high levels of social support. CONCLUSIONS: This study contribute to providing an understanding of how and when work-family conflict affects anxiety symptoms. The results implicate a wide range of interventions aimed at promoting mental wellbeing among female medical staff for policymakers and individuals.

RESUMO

A short term pot trail was employed to evaluate the exposure of mixed heavy metals (Cu, Pb and Zn) on growth, radial oxygen loss (ROL) and root anatomy in Bruguiera gymnorrhiza. The possible function of BgC4H, a cytochrome P450 gene, on root lignification was also discussed. The exposures of mixed Cu, Pb and Zn directly reduce O2 leakage at root surface. The reduced ROL inhibited by heavy metals was mainly ascribed by the changes in root anatomical features, such as decreased root porosity together with increased lignification within the exodermis. BgC4H was found to be up-regulated after 0.5-day metal exposure, and remained higher transcript levels within 3-day metal exposure when compared to control roots. Besides, the inhibited photosynthesis may also result in less oxygen can be transported to the underground roots. In summary, the mangrove B. gymnorrhiza appeared to react to external mixed metal contaminants by developing a lignified and impermeable exodermis, and such a root barrier induced by mixed Cu, Pb and Zn appeared to be an adaptive response to block metal ions enters into the roots.

RESUMO

The radial translocation of cadmium (Cd) from the root to the shoot is one of the major processes affecting Cd accumulation in rice (Oryza sativa L.) grains, but few studies have focused on Cd apoplastic transport in rice. The aim of this study was to determine how apoplastic barriers affect Cd translocation via the apoplastic pathway, Cd accumulation levels in upper parts (shoot and grains) of rice cultivars, and the possible mechanism involved. Hydroponic and soil pot trials were conducted to study the development and chemical constituents of apoplastic barriers and their permeability to bypass flow, and to determine Cd localization in the roots of rice cultivars with different Cd-accumulating characteristics. The Cd accumulation in upper parts was positively correlated with bypass flow in the root and the apparent Cd concentration in the xylem, indicating that the apoplastic pathway may play an important role in Cd root-shoot translocation in rice. Apoplastic barriers were deposited closer to the root tip and were thicker in low Cd-accumulating cultivars than in high Cd-accumulating cultivars. The amounts and rates of increase in lignin and suberin were significantly higher in ZD14 (a low Cd-accumulating cultivar) than in FYXZ (a high Cd-accumulating cultivar) under Cd stress, indicating that stronger barriers were induced by Cd in ZD14. The stronger and earlier formation of barriers in the low Cd-accumulating cultivar decreased bypass flow more efficiently, so that more Cd was retained in the root during apoplastic translocation. This was confirmed by localization analyses of Cd in root transverse sections. These results suggest that apoplastic barriers reduce Cd root-to-shoot translocation via the apoplastic pathway, leading to lower Cd accumulation in the upper parts of rice plants. Bypass flow may have the potential to be used as a rapid screening indicator for low Cd-accumulating rice cultivars.
