A study on the understanding of sterilisation in the central sterile services department by the healthcare personnel in a tertiary care hospital in Sikkim

Background: Globally, hundreds of millions of people are affected every year by avoidable infections in healthcare (healthcare-associated infections, [HAIs]). Through knowledge, best practices and infection prevention and control (IPC), we can prevent HAI to patients and health workers. Following recent threats caused by widespread epidemics and increasing awareness about the spread of antimicrobial resistance, several countries are paying more attention and investing resources to strengthening IPC infrastructures and improving practices. Objective: The objective was to assess the practices by the healthcare staff regarding the sterilisation process in the central sterilisation service department (CSSD) and to bring about improvements in the practices in the hospital. Materials and Methods: A cross-sectional study was conducted where the healthcare staff were given a set of questionnaires on sterilisation in the CSSD. The staff who participated in the study included doctors, intensive care unit nursing staff, infection control nurses, operation theatre nursing staff, CSSD staff and outpatient department nursing staff. Results: The questionnaire was administered to 120 health staff. All the staff agreed that instruments should be cleaned at the source. The majority of the participants (82%) believed that medical devices should be reprocessed centrally in CSSD; however, very few of them (18%) have felt otherwise. Almost 70% of staff did not know about the indicators used in CSSD and the zones in CSSD. The expiry date of the items once received from CSSD, 60% said it is not mentioned on the pack and 40% of participants agreed that it is mentioned on the pack. Conclusion: The processes of sterilisation and decontamination are complex, require specific infrastructure and equipment and involve several steps that need to be correct, from device collection, receipt by the unit, processing, storage and distribution them throughout the facility. Quality control measures to evaluate the proper functioning of the equipment are of the utmost importance.

ANALYSIS OFMODERN CYBERSECURITY THREAT TECHNIQUES ANDAVAILABLE MITIGATING METHODS

Modern means of communication have improved the way of life of humans around the world. Never has there been a time of unprecedented innovation in the way we humans communicate and share information with one another. Modern Technology has made it conceivable to keep in contact with our family, companions, and colleagues. Modern applications like Zoom, Google Hangout and Microsoft Teams have seen a geometric increase in new users and this growth has reflected the company’s share price. However, the use of modern technology has brought with it issues and concerns in terms of cyberthreats. This study helps to identify modern cybersecurity threats and how to effectively mitigate against them. The methodology used for this study was based on literature search and analysis, we also used model adaptation from generic ones. Our finding show that Organizations now need to grapple with these unprecedented threats and find effective solutions to protect their data, applications, and people from the risk of cyber-attacks and at the same time ensure they adhere strictly to regulatory requirements. This paper sheds light on the modern cyber security threat and identifies methods of mitigating against these threats. This paper can also be used as a Cyber security survival guide to investigate information and protect against cybersecurity threats in an organization. In conclusion, the aim of this paper review is to explore the more recent Cybersecurity threats and recommend effective method that can be adopted at an organizational level to guards against these persistent threats.

Neoextrativismo, garimpo e vulnerabilização dos povos indígenas como expressão de um colonialismo persistente no Brasil

ABSTRACT This essay argues that the most recent threats of vulnerability against indigenous peoples, intensified in the context of the COVID-19 pandemic, reflect a persistent colonialism. This is updated in the context of Brazil’s semi-peripheral insertion into the capitalist, neoliberal, and globalized world-system as an exporter of commodities produced by the two strategic sectors of neo-extractivism, mining and agribusiness. The neo-extractivist model benefits mainly transnational groups and national elites with great economic and political power, in addition to the financial sector. Moreover, it establishes connections with the underworld of inferior and illegal circuits linked to sectors such as mining, and ranges from practices of violence to money laundering with the participation of local groups that, in recent times, have been assuming growing political and institutional power. Such groups are part of the complex mosaic of the strengthening of far-right ideologies in recent years on the national scene, which have been gathering alliances. This essay is based on collaborative research experiences in recent years with the Munduruku people in the Middle Tapajós region, along with reflections on the current expansion of the anti-indigenous political agenda.

Trapped in the global? A look at the contemporary evolution of migration policies in Cameroon

ABSTRACT Recent debates on policies in Africa highlight their propensity to be globalized today and to see other actors acting significantly alongside the state. This configuration dates from the early 2000s and marks a break with the pattern and format of policies observed between 1960 and the late 1970s, on the one hand, and between 1980 and the late 1990s, on the other. Concerning migration, the European influence, motivated by a security rationale, is highlighted in the orientation of migration policies. Looking at Cameroonian migration policy, one can detect trajectories that contrast in some respects to the sequencing of public interventions mentioned above. This analysis mobilizes a socio-historical approach to discuss the main trends in the Cameroonian migration policy since the 1960s. A temporality that contrasts with the dynamics discussed in the literature for other sectors shows the importance of international dynamics in defining this policy. It also reveals that the security issue seems to have always influenced the content of this policy, according to various modalities and motivations. This point thus undermines the vision of a policy whose security inclination is linked to recent threats and driven by external actors.

Saving the sea turtles of Anguilla: Combining scientific data with community perspectives to inform policy decisions

Historic over-exploitation and the more recent threats caused by fisheries by-catch, disease and climate change have left sea turtle populations in the Wider Caribbean at risk of extinction. In 1995, following regional declines in nesting and foraging populations, the island of Anguilla implemented a moratorium on the hunting of turtles. At the request of the Government of Anguilla for scientific data to either support or remove the moratorium, comprehensive population estimates were obtained, and foraging, nesting and migratory movements were examined. In addition, community perspectives on turtles and their protection were assessed. Between 2015 and 18 surveys of 30 nesting beaches estimated low nesting activity with a maximum of 41 hawksbill, 15 green, and 1–2 leatherback turtles nesting in Anguilla annually. The inter-nesting range of hawksbills exhibited high levels of geographic overlap and occurred within 1.5 km of nesting beaches. Migratory tracks of hawksbill turtles traversed through seven exclusive economic zones, two of which allow a legal turtle fishery. Site fidelity was observed in foraging areas of green turtles and genetic analysis revealed population differentiation between green turtle foraging sites in Anguilla and between hawksbill rookeries in Anguilla compared to other Leeward Islands, indicating the individual importance of each foraging and nesting site. The Anguillan public (n = 302) overwhelmingly agreed with the current ban on harvesting sea turtles and considered turtles important for ecotourism. Our work provides a case-study, that can be applied globally, of how scientific research combined with community perspectives can effectively inform policy and ultimately protect endangered species, and highlights that local Governments provided with high quality data in a timely fashion for their policy making timetable are more likely to integrate findings into their decision-making process.

The Influence of Emotional Framing and Graph Complexity on Biases in Graphical Memory for COVID-19 Data in a Lifespan Sample.

The coronavirus disease 2019 (COVID-19) is one of the biggest recent threats to public health. People rely on news for up-to-date information during such major events, but news is often emotional in nature, which can affect how we learn and remember information. Additionally, graphs are widely used in news, but comprehension and memory for graphical information can be influenced by various factors, including emotions. We tested how the emotional framing of news would affect graphical memory across the lifespan. Participants studied a graph showing the number of weekly or daily new COVID-19 deaths after reading COVID-19 news framed as more positive or negative. Participants also reported their attitudes toward the pandemic, political leaning, news consumption habits, mood, and need for cognition. There was no overall difference in memory across conditions or age, but memory was more biased by the emotional framing of the news when the graphs were less visually complex. A number of exploratory correlations are also discussed. The findings indicate that framing news with a more positive or negative lens can bias understanding of and memory for related graphical information in some cases and can have implications for improving media literacy and public health compliance.

White Mango Scale (Aulacaspis tubercularis) Management approaches: A Review

There are different species of insects and diseases that contribute to low yield of mango tree throughout its stages of development. This review was intended to collect research works on white mango scale with special focus on research works done in Ethiopia. Different findings of research works on the insect were carefully studied. The white mango scale insect, Aulacaspis tubercularis (Hemiptera: Diaspididae) is a recent threat to mango production in Ethiopia which was introduced the first time in 2010 in western part of the country. It has spread to all mango producing areas of the country within a short period of time reducing the production and quality of mangos. Control measures taken against the white mango scale include use of chemical insecticides, quarantine, cultural practices, biological control using parasitoids and predators and integrated pest management. Quarantining the insect is the management method recommended in many cases. Generally, the current reports revealed that mango production in Ethiopia will be under serious threat which can even destroy total mango production in the future.

Mcr Genes Conferring Colistin Resistance in Enterobacterales; a Five Year Overview.

The present review aims to study and detect the global emergence of mcr genes in E. coli, K. pneumoniae and Salmonella spp., isolates from human specimens over the last six years. Nowadays the rise of multidrug-resistant superbugs has made essential the return of drugs that were previously abandoned. A clear example is colistin, which acts against multidrug - resistant gram - negative pathogens, including Enterobacterales. Colistin resistance is an unfortunate fact, with the emergence of mcr genes conferring resistance to colistin in Enterobacterales posing the most recent threat. Literature about mcr genes and their spread in E. coli, K. pneumoniae and Salmonella spp. is cited, focusing on the emergence of mcr genes in human specimens since 2015. The data were taken from the PubMed and Scopus databases. It seems that the mcr-1 gene continues to be the protagonist among the three species. E. coli is the dominant species harbouring mcr genes. Moreover, plasmid - mediated colistin resistance is also conferred upon other species that carry different genes resistant to antibiotics. There are only scarse reports on human Salmonella spp isolates harbouring mcr genes. Finally, the emergence of the mcr-9 gene in all of them is quite remarkable. CONCLUSION: Plasmid - mediated colistin resistance in Enterobacterales is a global issue and has been worsening over the years. The continuous mutations of mcr gene subtypes underline the need for better surveillance, constant investigation and wise use of colistin, especially in countries with high levels of antibiotic resistance.

Knowledge and perception of middle school students regarding COVID‐19 disease at the start of the pandemic

Facing recent threats of coronavirus disease (COVID‐19), an educational strategy was designed and applied to middle school students in order to reinforce related knowledge and behaviors. A group of 65 middle school students (14–18 years old) developed several designed online curricular activities. After the intervention, students answered a questionnaire to assess if they: (a) were familiar with the terms COVID 19 and SARS‐CoV‐2; (b) were conscious about the importance of preventive measures to stop the spread of this disease; (c) were engaged in these activities; (d) were motivated to research on health‐related issues. This study was a first to attempt to evaluate student's perceptions about SARS‐CoV‐2 infection and support education regarding COVID‐19, mainly on the reinforcement of preventive measures.

ArcelorMittal, Zenica: the logic of collective action

This article explores a recent successful threat of industrial action at the ArcelorMittal steel plant at Zenica, Bosnia and Herzegovina. Building in interviews with trade unions leaders, the author locates the campaign against the background of the economic, political and social situation in the country as well as the difficulties these impose on effective trade union organisation which, with certain exceptions, exists at a low level particularly in the private sector. Other aspects also make trade unions unattractive, not least to young people. Consequently, examples of industrial action which are successful are not only are of practical assistance in raising the wages of the workers involved, they also provide powerful examples of the continuing logic of collective action and, thus, a strong motivation to seek out trade union membership. Furthermore, in a country beset by the political problems that Bosnia and Herzegovina has, examples of strike action - of workers simply getting on with their everyday normal lives - also act to reassert what is most important by documenting citizens in their lives as workers not as ethnicities.

Real-time Privacy Preserving Framework for Covid-19 Contact Tracing

The recent unprecedented threat from COVID-19 and past epidemics, such as SARS, AIDS, and Ebola, has affected millions of people in multiple countries. Countries have shut their borders, and their nationals have been advised to self-quarantine. The variety of responses to the pandemic has given rise to data privacy concerns. Infection prevention and control strategies as well as disease control measures, especially real-time contact tracing for COVID-19, require the identification of people exposed to COVID-19. Such tracing frameworks use mobile apps and geolocations to trace individuals. However, while the motive may be well intended, the limitations and security issues associated with using such a technology are a serious cause of concern. There are growing concerns regarding the privacy of an individual’s location and personal identifiable information (PII) being shared with governments and/or health agencies. This study presents a real-time, trust-based contact-tracing framework that operates without the use of an individual’s PII, location sensing, or gathering GPS logs. The focus of the proposed contact tracing framework is to ensure real-time privacy using the Bluetooth range of individuals to determine others within the range. The research validates the trust-based framework using Bluetooth as practical and privacy-aware. Using our proposed methodology, personal information, health logs, and location data will be secure and not abused. This research analyzes 100,000 tracing dataset records from 150 mobile devices to identify infected users and active users.

Examining Recovery Status and Supports before and after Substance Abuse Disorder Treatment Among Clients Who Experienced Lifetime and Recent Firearm-Related Threats

Firearm-related risks have often been overlooked in the sequela of substance use and substance use disorders. This study compares adult substance abuse disorder treatment (SADT) clients who experienced recent ( n = 274) and lifetime ( n = 889) firearm threats to adults who were not threatened with a firearm ( n = 2029) before and 12 months after program entry. More men experienced firearm threats (38.8%) than women (34.2%). However, among those with any firearm threats, more women (27.2%) experienced firearm threats in the year before program entry than men (20.2%). Being threatened with a firearm was associated with increased economic vulnerability, criminal justice system involvement, mental health problems, and victimization both before and after SADT program entry. A higher number of adverse childhood experiences were associated with firearm threats and particularly recent firearm threats. Results of this study underscore the importance of screening for firearm-related risks in substance abuse disorder treatment programs.

Improving threat detection with a detection development life cycle

Threat detection is one of the main activities of an information security programme. Performing threat detection goes beyond deploying threat detection technologies. These technologies can be highly effective in their job of detecting threats, but their effectiveness is dependent on what detection specialists usually call detection content. Detection content is usually detached from the data analytics capabilities of the tool and needs to be constantly updated to ensure the most recent threats can be detected. These updates are generally developed by the detection technology provider as part of a subscription service, or by the organisation deploying and operating the technology, as part of activities commonly described as detection engineering. This paper describes the implementation and operation of a detection development life cycle (DDLC) process, which can be used to control the selection, creation and management of threat detection content.

An approach to categorize chest X-ray images using sparse categorical cross entropy

The Coronavirus disease (COVID-19) pandemic is the most recent threat to global health. Reverse transcription-polymerase chain reaction (RT-PCR) testing, computed tomography (CT) scans, and chest X-ray (CXR) images are being used to identify Coronavirus, one of the most serious community viruses of the twenty-first century. Because CT scans and RT-PCR analyses are not available in most health divisions, CXR images are typically the most time-saving and cost-effective tool for physicians in making decisions. Artificial intelligence and machine learning have become increasingly popular because of recent technical advancements. The goal of this project is to combine machine learning, deep learning, and the health-care sector to create a categorization technique for detecting the Coronavirus and other respiratory disorders. The three conditions evaluated in this study were COVID-19, viral Pneumonia, and normal lungs. Using X-ray pictures, this research developed a sparse categorical cross-entropy technique for recognizing all three categories. The proposed model had a training accuracy of 91% and a training loss of 0.63, as well as a validation accuracy of 81% and a validation loss of 0.7108.

Molecular docking and simulation studies of synthetic protease inhibitors against COVID-19: a computational study

COVID-19 is the most recent threat to global health. Many people preferred treatment in case of infection instead of vaccination. The inhibition of viral replication is a good strategy for the treatment of COVID-19 infection. 3CLpro and PLpro are two important viral proteases responsible for proteolysis, infection, and replication of the virus. Therefore, targeting of these two enzymes is an attractive way to deal with COVID-19. The aim of this study was to screen some synthetic protease inhibitors to determine an appropriate hit molecule against COVID-19 using molecular docking and molecular dynamic simulations. The strategy depends on docking existing synthetic compounds mostly HIV protease inhibitors against two COVID-19 proteases to identify promising drugs for the treatment of COVID-19. We used protein data bank to obtain the X-ray crystal structure of the most important COVID-19 proteases 3CL pro (PDB ID: 6M2N) and PL pro (PDB ID: 6WX4). In this conceptual context, an attempt has been made to suggest an in silico computational relationship between 50 synthetic protease inhibitors and COVID-19 proteases. Out of 50 screened compounds, the best docking scores were found for these five protease inhibitors BDBM7021, BDBM698, BDBM694, BDBM93239, BDBM700. A 100-ns MD simulation was carried out to assess the stability of COVID-19 proteases and inhibitors, revealing an average RMSD value of 0.7 and favorable binding free energy (MM-GBSA) for all complexes confirming their potency as powerful binders in the COVID-19 proteases’ binding pocket. Furthermore, the current results must be confirmed using in-vitro and in-vivo antiviral methods. Communicated by Ramaswamy H. Sarma

Building Cultural Heritage Resilience through Remote Sensing: An Integrated Approach Using Multi-Temporal Site Monitoring, Datafication, and Web-GL Visualization

In the American West, wildfires and earthquakes are increasingly threatening the archaeological, historical, and tribal resources that define the collective identity and connection with the past for millions of Americans. The loss of said resources diminishes societal understanding of the role cultural heritage plays in shaping our present and future. This paper examines the viability of employing stationary and SLAM-based terrestrial laser scanning, close-range photogrammetry, automated surface change detection, GIS, and WebGL visualization techniques to enhance the preservation of cultural resources in California. Our datafication approach combines multi-temporal remote sensing monitoring of historic features with legacy data and collaborative visualization to document and evaluate how environmental threats affect built heritage. We tested our methodology in response to recent environmental threats from wildfire and earthquakes at Bodie, an iconic Gold Rush-era boom town located on the California and Nevada border. Our multi-scale results show that the proposed approach effectively integrates highly accurate 3D snapshots of Bodie’s historic buildings before/after disturbance, or post-restoration, with surface change detection and online collaborative visualization of 3D geospatial data to monitor and preserve important cultural resources at the site. This study concludes that the proposed workflow enhances the monitoring of at-risk California’s cultural heritage and makes a call to action to employ remote sensing as a pathway to advanced planning.

Environmental activists’ hysteresis as a driving force for establishing environmental actions against urban forest privatization in Bandung, Indonesia

Despite the huge and growing environmental movement to protect urban forests in Indonesia, the tensions between environmental activists’ past engagements with nature and the emerging environmental problems are under-studied. The inner contradiction between the intensive nature of the connections and experiences that the actor maintains and the recent external threat to the environment is the key energizer of an environmental movement. Through Pierre Bourdieu’s seminal concept of hysteresis, this article explores how activists’ previous experiences with nature suffer disjuncture caused by the threat of urban forest privatization occurring in their neighborhood. Drawn from in-depth interviews with the co-founders of an environmental movement organization, the activist narratives in this article reveal that the development of their current struggles was driven by feelings of disappointment, anxiety, anger and a fear of losing the urban forest. The urban forest, for them, not only constitutes a physical space, but serves social and spiritual purposes, represents local identity and is the basis for everyday life.

A 900-year record of effective moisture in the Laurentian Great Lakes region

The (Laurentian) Great Lakes region (GLR) of North America contains ∼20% of the world's freshwater by total area. Yet, the water quantity and quality of lakes in this region are threatened by water level fluctuations and excessive algal growth associated with climate warming. To understand the mechanisms that drive these changes, we have established a 900-year history of environmental change using sediments from a small kettle lake, Barry Lake, located within the GLR. To understand how water quantity changed over time, we used stable isotopes of oxygen and carbon in marl to reconstruct effective moisture. Our reconstruction for Barry Lake shows that the Little Ice Age (LIA) was wetter than present, whereas the Medieval Climate Anomaly (MCA) was drier than present. There is considerable spatiotemporal variation in effective moisture across the GLR and northeastern (NE) USA. This variation may reflect changes in the sign of the Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO), which can alter moisture delivery by modifying the strength and position of the polar and subtropical jet streams. To identify changes in water quality, we reconstructed primary production using sedimentary chlorophyll a (Chl-a(s)) contents and stable isotopes of carbon and nitrogen in organic matter. There was relatively little change until the last 150 years, revealing that shifts in effective moisture did not noticeably influence primary production. Rather, primary production was impacted by anthropogenic pressures such as land use change and associated increases in nutrient delivery. Our research contextualizes recent threats to water quantity and quality in the GLR against a backdrop of environmental change, while also synthesizing hydroclimate records from across this region and the NE USA.

Leptospermum repo (Myrtaceae), a new species from northern Aotearoa / New Zealand peat bog habitats, segregated from Leptospermum scoparium s. l.

Leptospermum repo de Lange & L.M.H.Schmid sp. nov. (Myrtaceae) is segregated from L. scoparium J.R.Forst. & G.Forst. (sensu lato). The new species is endemic to the peat bogs of the Waikato, Bay of Plenty, and adjacent eastern ranges of the northern portion of Te Ika a Maui / North Island, Aotearoa / New Zealand. The new species belongs to the northern Te Ika a Maui / North Island clade of L. scoparium s. l., from whose other members it is morphologically distinguished by its gracile, spindly, open-branched growth habit; widely divergent, longer, linear, linear-lanceolate (rarely filiform), shortly cuspidate leaves; flowers with white petals, stamens mostly with white filaments (very rarely tinged pink near base), and by the style and stigma which are usually green (very rarely pink). Leptospermum repo now occupies ca. 10% of its former peat bog habitat, where aside from a few protected peat bogs the species is still in decline through loss of its habitat. A more recent potential threat to L. repo is myrtle rust disease, caused by Austropuccinia psidii, an exotic rust first detected in Aotearoa / New Zealand in May 2017. This rust poses a serious threat to the Myrtaceae of Aotearoa / New Zealand, for which there is at present no known effective treatment to prevent the death of infected hosts. Therefore, due to the historic loss of habitat, a threat which is still ongoing, causing the decline of many L. repo populations; and the potential threat of Austropuccinia psidii to this species, the listing proposed for the species (as Leptospermum aff. scoparium (c) (AK191319; "Waikato peat bog") by the New Zealand Indigenous Vascular Plant Threat Listing Panel of "Threatened / Nationally Critical DP, De" is here upheld.

Parallel evolution of Varroa resistance in honey bees: a common mechanism across continents?

The near-globally distributed ecto-parasitic mite of the Apis mellifera honeybee, Varroa destructor, has formed a lethal association with Deformed wing virus, a once rare and benign RNA virus. In concert, the two have killed millions of wild and managed colonies, particularly across the Northern Hemisphere, forcing the need for regular acaricide application to ensure colony survival. However, despite the short association (in evolutionary terms), a small but increasing number of A. mellifera populations across the globe have been surviving many years without any mite control methods. This long-term survival, or Varroa resistance, is consistently associated with the same suite of traits (recapping, brood removal and reduced mite reproduction) irrespective of location. Here we conduct an analysis of data extracted from 60 papers to illustrate how these traits connect together to explain decades of mite resistance data. We have potentially a unified understanding of natural Varroa resistance that will help the global industry achieve widespread miticide-free beekeeping and indicate how different honeybee populations across four continents have resolved a recent threat using the same suite of behaviours.
