    猪废水(SW),以高度复杂的有机和营养物质为特征,对水生环境和公众健康造成严重影响。此外,SW拥有具有巨大经济潜力的宝贵资源。因此,SW处理技术越来越重视资源回收,在逐步走向节能的同时,可持续性循环经济原则。这篇综述全面地概括了治疗SW的最新知识,包括常规(即,人工湿地,空气汽提和有氧系统)和基于资源利用的(即,厌氧消化,膜分离,厌氧氨氧化,微生物燃料电池,和基于微藻的系统)技术。此外,本研究还阐述了影响SW治疗性能的关键因素,如pH值,温度,溶解氧,水力停留时间和有机负荷率。再利用能源的潜力,还总结了SW处理过程中产生的生物质和消化物。此外,与全面实施相关的障碍,长期治疗,节能设计,强调了各种基于资源利用的SW处理技术的养分回收。此外,未来的研究前景,例如流程优化的优先级,深入探索微生物机制,提高能量转换效率,以及各种技术的集成,强调扩大工程应用,建立可持续的SW处理系统。
    Swine wastewater (SW), characterized by highly complex organic and nutrient substances, poses serious impacts on aquatic environment and public health. Furthermore, SW harbors valuable resources that possess substantial economic potential. As such, SW treatment technologies place increased emphasis on resource recycling, while progressively advancing towards energy saving, sustainability, and circular economy principles. This review comprehensively encapsulates the state-of-the-art knowledge for treating SW, including conventional (i.e., constructed wetlands, air stripping and aerobic system) and resource-utilization-based (i.e., anaerobic digestion, membrane separation, anaerobic ammonium oxidation, microbial fuel cells, and microalgal-based system) technologies. Furthermore, this research also elaborates the key factors influencing the SW treatment performance, such as pH, temperature, dissolved oxygen, hydraulic retention time and organic loading rate. The potentials for reutilizing energy, biomass and digestate produced during the SW treatment processes are also summarized. Moreover, the obstacles associated with full-scale implementation, long-term treatment, energy-efficient design, and nutrient recovery of various resource-utilization-based SW treatment technologies are emphasized. In addition, future research prospective, such as prioritization of process optimization, in-depth exploration of microbial mechanisms, enhancement of energy conversion efficiency, and integration of diverse technologies, are highlighted to expand engineering applications and establish a sustainable SW treatment system.

    移动健康(mHealth)干预措施可有效改善慢性病管理,主要在高收入国家。然而,人们对mHealth干预措施对减少心血管危险因素的功效知之甚少,包括高血压和糖尿病,在低收入和中等收入国家正在迅速增加。
    本研究旨在评估mHealth干预措施对非洲糖尿病和高血压管理的有效性。
    我们搜索了PubMed,科克伦图书馆,谷歌学者,非洲在线期刊,和WebofScience从开始到2022年7月发表的相关研究。感兴趣的主要结果是血红蛋白A1c(HbA1c)的变化,收缩压,和舒张压。随机或固定效应模型用于荟萃分析,I2统计量用于衡量研究异质性。Z检验和P值用于评估mHealth干预措施对HbA1c和血压水平的影响。
    本综述包括7项研究(随机对照试验),共有2249名参与者。两项研究评估了mHealth对血糖控制的影响,5项研究评估了mHealth对血压控制的影响。在糖尿病患者中,使用m健康干预措施与HbA1c水平的显著降低(加权平均差异[WMD]0.20,95%CI-0.40至0.80;P=.51),收缩压(WMD-1.39,95%CI-4.46至1.68;P=.37)和舒张压(WMD0.36,95%CI-1.37至2.05;P=.69)无关。在使用留一法进行敏感性分析后,Kingue等人的研究对干预有影响,导致收缩压降低2mmHg(WMD-2.22,95%CI-3.94~-0.60;P=.01),但省略研究后,舒张压和HbA1c水平无显著差异.
    我们的综述没有提供确凿的证据证明mHealth干预措施在非洲糖尿病和高血压患者中降低血压和血糖控制的有效性。为了证实这些发现,需要更大的随机对照试验.
    Mobile health (mHealth) interventions are effective in improving chronic disease management, mainly in high-income countries. However, less is known about the efficacy of mHealth interventions for the reduction of cardiovascular risk factors, including for hypertension and diabetes, which are rapidly increasing in low- and middle-income countries.
    This study aimed to assess the efficacy of mHealth interventions for diabetes and hypertension management in Africa.
    We searched PubMed, Cochrane Library, Google Scholar, African Journals Online, and Web of Science for relevant studies published from inception to July 2022. The main outcomes of interest were changes in hemoglobin A1c (HbA1c), systolic blood pressure, and diastolic blood pressure. The random or fixed effect model was used for the meta-analysis, and the I2 statistic was used to gauge study heterogeneity. Z tests and P values were used to evaluate the effect of mHealth interventions on HbA1c and blood pressure levels.
    This review included 7 studies (randomized controlled trials) with a total of 2249 participants. Two studies assessed the effect of mHealth on glycemic control, and 5 studies assessed the effect of mHealth on blood pressure control. The use of mHealth interventions was not associated with significant reductions in HbA1c levels (weighted mean difference [WMD] 0.20, 95% CI -0.40 to 0.80; P=.51) among patients with diabetes and systolic blood pressure (WMD -1.39, 95% CI -4.46 to 1.68; P=.37) and diastolic blood pressure (WMD 0.36, 95% CI -1.37 to 2.05; P=.69) among patients with hypertension. After conducting sensitivity analyses using the leave-one-out method, the Kingue et al study had an impact on the intervention, resulting in a 2 mm Hg reduction in systolic blood pressure (WMD -2.22, 95% CI -3.94 to -0.60; P=.01) but was nonsignificant for diastolic blood pressure and HbA1c levels after omitting the study.
    Our review provided no conclusive evidence for the effectiveness of mHealth interventions in reducing blood pressure and glycemic control in Africa among persons with diabetes and hypertension. To confirm these findings, larger randomized controlled trials are required.

    微塑料已被证明是关键的环境污染问题之一。此外,微纤维,环境中最突出的微塑料形式,同样引起了各国的注意。随着全球人口和工业化的增加,纤维的生产和使用逐年增加。因此,形成大量的微纤维。如果未正确使用或处理纤维产品,会造成直接/间接的严重超细纤维环境污染。微纤维在进入自然环境时会进一步破碎成更小的纤维碎片。目前,研究人员在微纤维的识别方面进行了广泛的研究,为进一步的机智研究奠定基础。本文利用文献计量分析对超细纤维污染研究进行了系统综述。首先,分析了超细纤维的主要来源及其影响因素。我们旨在总结服装纤维制备和护理过程对微纤维形成的影响。然后,这项工作详细阐述了水中/水之间的迁移,大气,和陆地环境。我们还讨论了超细纤维对生态系统的影响。最后,超细纤维目前和可预见的有效治疗方法,处置,并对资源利用方法进行了说明。本文将为今后的超细纤维研究提供结构化参考。
    Microplastics have been proven to be one of the critical environmental pollution issues. Moreover, microfibers, the most prominent form of microplastics in the environment, have likewise attracted the attention of various countries. With the increase in global population and industrialization, the production and use of fibers continue to increase yearly. As a result, a large number of microfibers are formed. If fiber products are not used or handled correctly, it will cause direct/indirect severe microfiber environmental pollution. Microfibers will be further broken into smaller fiber fragments when they enter the natural environment. Presently, researchers have conducted extensive research in the identification of microfibers, laying the foundation for further resourcefulness research. This work used bibliometric analysis to review the microfiber contamination researches systematically. First, the primary sources of microfibers and the influencing factors are analyzed. We aim to summarize the influence of the clothing fiber preparation and care processes on microfiber formation. Then, this work elaborated on the migration in/between water, atmosphere, and terrestrial environments. We also discussed the effects of microfiber on ecosystems. Finally, microfibers\' current and foreseeable effective treatment, disposal, and resource utilization methods were explained. This paper will provide a structured reference for future microfiber research.

    COVID-19是一种新兴的流行病,迅速发展的公共卫生紧急情况,一个国家的医疗保健系统可能面临重症监护病房(ICU)病床和器官支持需求的显着激增。在医疗资源不足的地区,这可能会进一步加剧现有的短缺,限制ICU提供正常标准护理的能力。它可以在道德或法律上提出有关如何优先分配挽救生命的医疗资源的问题。在像印度这样的发展中国家,仍然有许多医院受到竞争优先事项的挑战,并且仍然准备不足。在COVID-19大流行之后,指导资源匮乏地区的重症监护灾难计划人员,并确保ICU准备就绪,这篇综述分享了我们利用现有和替代资源准备ICU的经验和策略,专注于空间,设备,以及医护人员的安全和培训。
    COVID-19 pandemic is an emerging, rapidly evolving public health emergency where a nation\'s health-care system can face a marked surge in demand for intensive care unit (ICU) beds and organ support. In regions with insufficient medical resources, it may further aggravate the existing shortage, limiting an ICU\'s ability to provide the normal standard of care. It can present ethically or legally demanding questions about how to prioritize the allocation of life-saving medical resources. In developing countries like India, still many hospitals are challenged by competing priorities and remain underprepared. In the wake of COVID-19 pandemic, to guide the intensive care disaster planners in regions with low resources and to ensure ICU readiness, this review shares our experience and strategies for preparing ICU with existing and alternative resources, focusing on space, equipment, and health-care workers\' safety and training.

    OBJECTIVE: Coronavirus disease 19 (COVID-19) is a major cause of hospital admission and represents a challenge for patient management during intensive care unit (ICU) stay. We aimed to describe the clinical course and outcomes of COVID-19 pneumonia in critically ill patients.
    METHODS: We performed a systematic search of peer-reviewed publications in MEDLINE, EMBASE and the Cochrane Library up to 15th August 2020. Preprints and reports were also included if they met the inclusion criteria. Study eligibility criteria were full-text prospective, retrospective or registry-based publications describing outcomes in patients admitted to the ICU for COVID-19, using a validated test. Participants were critically ill patients admitted in the ICU with COVID-19 infection.
    RESULTS: From 32 articles included, a total of 69 093 patients were admitted to the ICU and were evaluated. Most patients included in the studies were male (76 165/128 168, 59%, 26 studies) and the mean patient age was 56 (95%CI 48.5-59.8) years. Studies described high ICU mortality (21 145/65 383, 32.3%, 15 studies). The median length of ICU stay was 9.0 (95%CI 6.5-11.2) days, described in five studies. More than half the patients admitted to the ICU required mechanical ventilation (31 213/53 465, 58%, 23 studies) and among them mortality was very high (27 972/47 632, 59%, six studies). The duration of mechanical ventilation was 8.4 (95%CI 1.6-13.7) days. The main interventions described were the use of non-invasive ventilation, extracorporeal membrane oxygenation, renal replacement therapy and vasopressors.
    CONCLUSIONS: This systematic review, including approximately 69 000 ICU patients, demonstrates that COVID-19 infection in critically ill patients is associated with great need for life-sustaining interventions, high mortality, and prolonged length of ICU stay.

    The tides are a predictable, renewable, source of energy that, if harnessed, can provide significant levels of electricity generation. The Alderney Race (AR), with current speeds that exceed 5 m s-1 during spring tides, is one of the most concentrated regions of tidal energy in the world, with the upper-bound resource estimated at 5.1 GW. Owing to its significance, the AR is frequently used for model case studies of tidal energy conversion, and here we review these model applications and outcomes. We examine a range of temporal and spatial modelling scales, from regional models applied to resource assessment and characterization, to more detailed models that include energy extraction and array optimization. We also examine a range of physical processes that influence the tidal energy resource, including the role of waves and turbulence in tidal energy resource assessment and loadings on turbines. The review discusses model validation, and covers a range of numerical modelling approaches, from two-dimensional to three-dimensional tidal models, two-way coupled wave-tide models, Large Eddy Simulation (LES) models, and the application of optimization techniques. The review contains guidance on model approaches and sources of data that can be used for future studies of the AR, or translated to other tidal energy regions. This article is part of the theme issue \'New insights on tidal dynamics and tidal energy harvesting in the Alderney Race\'.

    Mitochondria play a significant role in many biological systems. There is emerging evidence that differences in the mitochondrial genome may contribute to multiple common diseases, leading to an increasing number of studies exploring mitochondrial genomics. There is often a large amount of complex data generated (for example via next generation sequencing), which requires optimised bioinformatics tools to efficiently and effectively generate robust outcomes from these large datasets. Twenty-four online resources dedicated to mitochondrial genomics were reviewed. This \'mitochondrial toolbox\' summary resource will enable researchers to rapidly identify the resource(s) most suitable for their needs. These resources fulfil a variety of functions, with some being highly specialised. No single tool will provide all users with the resources they require; therefore, the most suitable tool will vary between users depending on the nature of the work they aim to carry out. Genetics resources are well established for phylogeny and DNA sequence changes, but further epigenetic and gene expression resources need to be developed for mitochondrial genomics.

    A cascade of reviews and growing body of literature exists on forest invasion ecology, its mechanism or causes; however, no review addressed the sustainable management of invasive plants of forest in totality. Henceforth, the present paper aims to provide a critical review on the management of invasive species particularly in the context of forest plants. Plant invasion in forest is now increasingly being recognized as a global problem, and various continents are adversely affected, although to a differential scale. Quest for the ecological mechanism lying behind the success of invasive species over native species of forest has drawn the attention of researches worldwide particularly in the context of diversity-stability relationship. Transport, colonization, establishment, and landscape spread may be different steps in success of invasive plants in forest, and each and every step is checked through several ecological attributes. Further, several ecological attribute and hypothesis (enemy release, novel weapon, empty niche, evolution of increased competitive ability, etc.) were proposed pertaining to success of invasive plant species in forest ecosystems. However, a single theory will not be able to account for invasion success among all environments as it may vary spatially and temporally. Therefore, in order to formulate a sustainable management plan for invasive plants of forest, it is necessary to develop a synoptic view of the dynamic processes involved in the invasion process. Moreover, invasive species of forest can act synergistically with other elements of global change, including land-use change, climate change, increased concentrations of atmospheric carbon dioxide, and nitrogen deposition. Henceforth, a unified framework for biological invasions that reconciles and integrates the key features of the most commonly used invasion frameworks into a single conceptual model that can be applied to all human-mediated invasions.
