Ecosystems are subject to various stress factors, such as temperature rises due to climate changes and metal disposal. Thermal stress can amplify or mask the effects of metals on aquatic organisms. This study aims to carry out a systematic review on the effects of temperature rises due to climate changes on the toxicity of metals for freshwater organisms. Searches were made in different electronic databases and article selection was based on the following inclusion criteria: concordance with the question of a systematic review; publication in English, Spanish, and Portuguese between 1960 and 2020; and the use of standard methodology. Forty-three articles were included, which were classified with respect to the year and country of publication, test-organisms and metals studied, temperatures tested, and the effects observed. In 80% of the studies analyzed, a temperature rise was responsible for increasing the toxicity of metals for the aquatic organisms. The temperatures studied contemplated the temperature rise predicted by the Intergovernmental Panel for Climate Change at the end of the 21st century. Brazil stood out among the countries for having the greatest number of research studies in this area, although there is still the need for an increase in studies in tropical climate regions. Based on the literature review, it was shown that the metals most studied were copper and cadmium and the test-organisms most used in the research projects were fish. The information obtained from ecotoxicological studies is essential to predict the effects and prevent the risks associated with the metal contamination of aquatic ecosystems due to climate changes.

The advancement made in biomedical industry upsurges the consumption rate of pharmaceutical drugs. The lack of proper monitoring and regulation methods leads to the unregulated discharge of pharmaceuticals in wastewater, where it can affect the aquatic organisms. Anticancer drugs are also known as cytostatic drugs mainly used for the treatment of cancer by disrupting the cell function and prevent multiplication of cancerous cell. Therefore, anticancer drugs are suspected to pose potential risk on environment by influencing mutagenic effects on the cells of aquatic organisms. An extensive research has been already made in the field of pharmaceutical removal, however their application on the removal of anticancer drugs is limited. This review paper elucidates about different electrochemical techniques for the mitigation of cytostatic drugs.

AbstractConstraints and limits to adaptation are critical to understanding the extent to which human and natural systems can successfully adapt to climate change. We conduct a systematic review of 1,682 academic studies on human adaptation responses to identify patterns in constraints and limits to adaptation for different regions, sectors, hazards, adaptation response types, and actors. Using definitions of constraints and limits provided by the Intergovernmental Panel on Climate Change (IPCC), we find that most literature identifies constraints to adaptation but that there is limited literature focused on limits to adaptation. Central and South America and Small Islands generally report greater constraints and both hard and soft limits to adaptation. Technological, infrastructural, and ecosystem-based adaptation suggest more evidence of constraints and hard limits than other types of responses. Individuals and households face economic and socio-cultural constraints which also inhibit behavioral adaptation responses and may lead to limits. Finance, governance, institutional, and policy constraints are most prevalent globally. These findings provide early signposts for boundaries of human adaptation and are of high relevance for guiding proactive adaptation financing and governance from local to global scales.

The Amazon has the highest richness of freshwater organisms in the world, which has led to a multitude of hypotheses on the mechanisms that generated this biodiversity. However, most of these hypotheses focus on the spatial distance of populations, a framework that fails to provide an explicit mechanism of speciation. Ecological conditions in Amazon freshwaters can be strikingly distinct, as it has been recognized since Alfred Russel Wallace’s categorization into black, white, and blue (= clear) waters. Water types reflect differences in turbidity, dissolved organic matter, electrical conductivity, pH, amount of nutrients and lighting environment, characteristics that directly affect the sensory abilities of aquatic organisms. Since natural selection drives evolution of sensory systems to function optimally according to environmental conditions, the sensory systems of Amazon freshwater organisms are expected to vary according to their environment. When differences in sensory systems affect chances of interbreeding between populations, local adaptations may result in speciation. Here, we briefly present the limnologic characteristics of Amazonian water types and how they are expected to influence photo-, chemical-, mechano-, and electro-reception of aquatic organisms, focusing on fish. We put forward that the effect of different water types on the adaptation of sensory systems is an important mechanism that contributed to the evolution of fish diversity. We point toward underexplored research perspectives on how divergent selection may act on sensory systems and thus contribute to the origin and maintenance of the biodiversity of Amazon aquatic environments.

Opportunistic Bacteria

Opportunistic bacteria are microorganisms that have been isolated from a host suffering from stress as a result of parasitic infestation. In this study, two bacterial species, namely Aeromonas hydrophila and Rhizobium radiobacter, were isolated from Trypauchen vagina fish that were infected with Microsporidian parasite cysts from Iraqi marine waters. The infection were mass implanted in the internal and external skeletal muscles and under the gill cover. Many symptoms of bacterial infection were observed in the fish, including flatulence with haemorrhagic fluids, skin disscolouration blackening, separation of crusts, and deformities in the area. The two bacterial species were characterised morphologically and identified using Vitek II system (Biomerieux - USA). To control infection, antibiotic susceptibility was performed using six antibiotics: nalidixic acid, nitrofurantoin, gentamicin, streptomycin, tetracycline and amoxicillin, both bacteria showed high antibiotic resistance. Identification of opportunistic bacteria has a pivotal role in preventing stress factors in fish, treating infections and alleviating their impact on other aquatic organisms.

The socio-ecological systems (SESs) framework provides cross-disciplinary insight into complex environmental problems. Numerous studies have applied the SES framework to coastal and marine environments over the last two decades. We review and analyze 98 of those studies to (i) describe how SES concepts were examined and measured, (ii) describe how the studies included feedbacks and thresholds, and (iii) identify and analyze elements unique to coastal and marine SES frameworks. We find that progress has been made in understanding key SES properties in coastal and marine ecosystems, which include resilience, adaptive capacity, vulnerability, and governance. A variety of methods has been developed and applied to analyze these features qualitatively and quantitatively. We also find that recent studies have incorporated land-based stressors in their analyses of coastal issues related to nutrient runoff, bacterial pollution, and management of anadromous species to represent explicit links in land-to-sea continuums. However, the literature has yet to identify methods and data that can be used to provide causal evidence of non-linearities and thresholds within SES. In addition, our findings suggest that greater alignment and consistency are needed in models with regard to metrics and spatial boundaries between ecological and social systems to take full advantage of the SES framework and improve coastal and marine management.

AimsThis evaluation aimed to identify patient, practitioner and infrastructural barriers to initiation of clozapine treatment in patients with treatment-resistant schizophrenia (TRS). In response to recent research supporting use of clozapine as the most effective treatment for patients with TRS, concerted efforts have been made to establish why clozapine is underutilised in the NHS. Following a study conducted by South London and Maudsley NHS Foundation Trust, which identified barriers and made recommendations, this evaluation aimed to identify barriers to initiation of clozapine in patients under the care of Mersey Care NHS Foundation Trust.This evaluation also aimed to make further recommendations to increase use of clozapine in Mersey Care's TRS patients and assess whether there have been any differences to concerns about clozapine initiation compared to previous evaluations.MethodAn online questionnaire containing a series of Likert scales was e-mailed to all Consultant Psychiatrists in Mersey Care NHS Foundation Trust. The questionnaire asked Consultants to rate how often they felt a range of barriers interfered with successful initiation of Clozapine treatment. The barriers chosen were based on the 2019 systematic review “Barriers to using clozapine in treatment-resistant schizophrenia.”ResultNineteen consultant psychiatrists completed the online questionnaire. All 19 indicated they either “agreed” (16%) or “strongly agreed” (84%) that they were confident in diagnosing TRS. This was a significant increase compared to the South London and Maudsley evaluation, with only 81% of participants in that study being “fairly familar” or “very familiar” with clozapine guidelines.Furthermore, concerns about inadequate blood testing facilities appear to have been addressed, with no participants in this evaluation staing there were insufficient blood testing facilities. However, 53% of Consultants who completed this evaluation stated they “often” (37%) or “very often” (16%) have patients who refuse clozapine because of the requirement for regular blood testing. Refusal to agree to required blood testing was the commonest reason identified for failure to initiate clozapine in TRS patients. This was consistent with the results from the South London and Maudsley study.ConclusionThose Mersey Care consultants surveyed identified that providing patients with further information about clozapine would be the most valuable intervention to increase likelihood of uptake of clozapine in the treatment of TRS. Significant progress has been made in improving the likelihood that clozapine can be successfully initiated, especially in the removal of practitioner barriers. This evaluation suggests interventions should now be aimed at reducing patient barriers to initiation of treatment.

Horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare, inherited disorder characterized by a congenital absence of conjugate horizontal eye movements with progressive scoliosis developing in childhood and adolescence. Mutations in the Roundabout (ROBO3) gene located on chromosome 11q23–25 are responsible for the development of horizontal gaze palsy and progressive scoliosis. However, some studies redefined the locus responsible for this pathology to a 9-cM region. This study carried out a systematic review in which 25 documents were analyzed, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. The search was made in the following electronic databases from January 1995 to October 2019: PubMed, Scopus, Web of Science, PEDRO, SPORT Discus, and CINAHL. HGPPS requires a multidisciplinary diagnostic approach, in which magnetic resonance imaging might be the first technique to suggest the diagnosis, which should be verified by an analysis of the ROBO3 gene. This is important to allow for adequate ocular follow up, apply supportive therapies to prevent the rapid progression of scoliosis, and lead to appropriate genetic counseling.

While much progress has been made in promoting inclusive finance through the ownership of a basic personal account, billions of people in developed and emerging markets are still underrepresented in financial services. Also, they are unable to contribute to the provision of better access to financial services. The purpose of this study was defined as to explore the contribution of digital financial services (DFSs) in promoting inclusive finance in China. This study presents a theoretical discussion on how DFSs play an important role in promoting China’s inclusive finance. This study uses the systematic review method of qualitative sampling to achieve the goal of this study. Different forces play different roles behind the promotion of inclusive finance. However, DFSs are considered to be one of the most influential forces in the development of inclusive finance in the present world. Many examples of how DFS can improve inclusive finance are discussed in the literature. In addition, different contributions to DFS usage are presented here to achieve the objectives of this study. The contents of the study contributed to a better understanding of the practical impact and implication of DFS tools in transforming the financial sector. In this study, first, a structured review method is followed; second, most important discussion on the contribution of DFS in promoting inclusive finance is presented and third, the relation between the topic and related research is identified.
