Uncontrolled production of oxygen and nitrogen radicals results in oxidative and nitrosative stresses that impair cellular functions and have been regarded as causative common denominators of many pathological processes. In this review, we report on the beneficial effects of molecular hydrogen in scavenging radicals in an artificial system of•OH formation. As a proof of principle, we also demonstrate that in rat hearts in vivo, administration of molecular hydrogen led to a significant increase in superoxide dismutase as well as pAKT, a cell survival signaling molecule. Irradiation of the rats caused a significant increase in lipid peroxidation, which was mitigated by pre-treatment of the animals with molecular hydrogen. The nuclear factor erythroid 2-related factor 2 is regarded as an important regulator of oxyradical homeostasis, as well as it supports the functional integrity of cells, particularly under conditions of oxidative stress. We suggest that the beneficial effects of molecular hydrogen may be through the activation of nuclear factor erythroid 2-related factor 2 pathway that promotes innate antioxidants and reduction of apoptosis, as well as inflammation.

Abstract Background Higher valency pneumococcal conjugate vaccines (PCV10 and PCV13) replaced PCV7, and an updated global analysis of PCV impact on invasive pneumococcal disease (IPD) incidence is needed. We aimed to estimate the change in vaccine-type (VT), non-VT type and all-serotype (ST) IPD incidence following introduction of PCV10/13 among children < 5 years of age. Methods IPD ST-specific incidence or cases and population denominators were obtained directly from surveillance sites. IPD incidence rate ratios (IRRs) for each site were estimated comparing the pre-any PCV incidence to each post-PCV10/13 year using Bayesian multi-level, mixed effects Poisson regressions. All-site weighted average IRRs were estimated using linear mixed-effects regressions. Results were stratified by product (PCV10 vs. PCV13) and years of prior PCV7 use (none, some [1-3 years or 4-5 years if < 70% PCV uptake], or many [≥ 4 years with ≥ 70% uptake]). Results Analyses included 45 surveillance sites from 31 countries, primarily high-income (80%). Thirty surveillance sites had pre- and post-PCV data (PCV10: no prior PCV7=5 sites, some=2, many=2; PCV13: no prior PCV7=3, some=5, many=13). Five years after PCV10/13 introduction, the all-site IRRs in children < 5 years were generally similar across products and prior PCV7 use strata for all-serotype IPD (range 0.23-0.41), PCV7 STs (0.01-0.13), PCV10non7 STs (1, 5, and 7F; 0.05-0.20), and ST6A (0.01-0.18). IRRs for ST19A were lower for PCV13 sites (range by PCV7 use: 0.09-0.31) than for PCV10 sites (1.1-1.4). ST3 IRRs were dynamic, differing by product at year 5 (range for PCV13 sites=0.86-1.02; PCV10 sites=1.55-1.78), but converging by year 7. NonPCV13 STs increased across all strata (range 1.9-2.6), except one strata with a single African site that declined. Figure 1. All-Site Weighted Average Incidence Rate Ratios, Children <5> * Total sites indicates number of sites with incidence rate data included and pre/post sites indicates number of sites with both pre- and post-PCV data to estimate IRRs for each outcome. ** Year 0 indicates the year of PCV10/13 introduction and year -1 indicates the last year of PCV7 use prior to PCV10/13 introduction. Conclusion All-serotype IPD in children < 5 years declined following both PCV10 and PCV13 use, driven by substantial declines in VT serotypes and offset by increases in nonPCV13 STs. ST19A decreased among PCV13-sites, mitigating replacement disease occurring after PCV7 use, but increased, on average, among PCV10-sites. Changes in ST3 were heterogeneous, increasing in some sites and no change from baseline in others. Data from low-income and high-burden settings were limited. Disclosures Julia C.

Full textAbstract:
The diffusion of the Indo-Pacific concept in India’s strategic vocabulary has accompanied the emergence of a broader strategic reference frame, in which the impacts of climate change on coastal areas and maritime-related environmental issues figure among the lowest common denominators of cooperation at the regional scale. In the Indian Ocean Region (IOR), unregulated fishing, natural disasters relief or marine pollution indeed became major security concerns for littoral States as well as it gave a new role for the armies in mitigating increasing environmental risks. In fact, we are seeing an expansion in India-France maritime security cooperation, with particular focus on the Indian Ocean. With its expanding economic, marine military, and strategic goals in the Indo-Pacific region, India is eager to develop connections with countries throughout the area. France is emphasising its identity as an Indo-Pacific nation and showing interest in bolstering its partnership with India. The Indian Ocean has emerged as a hot topic in recent Indo-French bilateral talks, as both nations seek to broaden their long-standing strategic partnership to the maritime domain. In February 2022, they inked a roadmap to boost their bilateral exchanges on the blue economy and forge a common vision of ocean governance on the basis of the rule of law, and cooperation on sustainable and resilient coastal and waterways infrastructure (MEA, Feb 2022).[i] In this regard, both agreed to explore the potential for collaboration in marine science research for a better understanding of the oceans, including the Indian Ocean. One such partnership is the ‘The Indo-Pacific Oceans Initiative’ (IPOI), wherein France and India have taken the responsibility of being the ‘lead’ for the Marine Resources Pillar, which is one of seven identified pillars (MEA, Mar 2022).[ii] In such a context, this paper aims to explore India’s cooperation opportunities in the field of environmental security in the IOR in the context of Indo-French relations. As a preferred net security provider in the region, India has made of France one of the cornerstones of its SAGAR policy and a first-choice partner on maritime issues, as testified recently by the India-France Roadmap on Blue Economy and Ocean Governance. Based on several years of research on Indo-French relations and environmental security in the Indo-Pacific, the paper will first compare the securitization process of maritime-related environmental issues within the regional security policies of both countries and the adaptation of their navies to emerging environmental risks in the Indian Ocean. Then, it will analyse to what extent this process contributes to reshape military-to-military cooperation between the two navies/coast guard in emerging areas such as disaster relief operations, protection of maritime ecosystems or cyclone early warning. Then, it will consider the multilateral implications of this cooperation and its potential contribution to the security architecture of the Indian Ocean.

Outbreaks of election-related violence can be devastating, but experience has shown that they can be prevented. The need for improved efficiency of electoral violence early warning and prevention is increasingly argued. Good practices – developed nationally, regionally and globally – offer useful understanding of the phenomenon and of what can be done to improve prevention and mitigation. Although diverse and contingent on mandates and contexts in which organisations operate, early warning and prevention methodologies have common denominators that can be comparatively analysed. The establishment of national infrastructures for peace, which are also mandated to coordinate early warning, prevention and mitigation of electoral violence, helps to ensure that the impact of such efforts is maximised.

Small island nations are increasingly imperiled by larger nations that are emitting most of the greenhouse gases, forcing changes in the global climate, and causing catastrophic ecological and social problems. Among the most adversely affected people are islanders who are suffering immense health, economic, and cultural injustices that should be addressed at all levels of governance. Leaders of Anglican, Eastern Orthodox, and Roman Catholic denominations have been responding meaningfully to the plight of the small island nations by drawing motivation from their theological traditions for mitigating the problems and calling all Christians to act individually, collectively within their parishes, and collaboratively in the public square.

Active shooting violence at confined settings, such as educational institutions, poses serious security concerns to public safety. In studying the effects of active shooter scenarios, the common denominator associated with all events, regardless of reason/intent for shooter motives, or type of weapons used, was the location chosen and time expended between the beginning of the event and its culmination. This in turn directly correlates to number of casualties incurred in any given event. The longer the event protracts, the more casualties are incurred until law enforcement or another barrier can react and culminate the situation.Objective: Using AnyLogic technology, devise modeling scenarios to test multiple hypotheses against free-agent modeling simulation to determine the best method to reduce casualties associated with active shooter scenarios.Design, setting, subjects: Test four possible scenarios of responding to active shooter in a public school setting using agent-based computer modeling techniques—scenario 1: basic scenario where no access control or any type of security is used within the school; scenario 2, scenario assumes that concealed carry individual(s) (5-10 percent of the work force) are present in the school; scenario 3, scenario assumes that the school has assigned resource officer; scenario 4, scenario assumes that the school has assigned resource officer and concealed carry individual(s) (5-10 percent) present in the school.Main outcomes measured: Statistical data from modeling scenarios indicating which tested hypothesis resulted in fewer casualties and quicker culmination of event.Results: The use of AnyLogic proved the initial hypothesis that a decrease on response time to an active shooter scenario directly reduced victim casualties.Conclusions: Modeling tests show statistically significant fewer casualties in scenarios where on-scene armed responders such as resource officers and concealed carry personnel were present.

Full textAbstract:
Erectile dysfunction (ED) is a condition with multifactorial pathogenesis, quite common among men, especially those above 60 years old. A vascular etiology is the most common cause. The interaction between chronic inflammation, androgens, and cardiovascular risk factors determines macroscopically invisible alterations such as endothelial dysfunction and subsequent atherosclerosis and flow-limiting stenosis that affects both penile and coronary arteries. Thus, ED and cardiovascular disease (CVD) should be considered two different manifestations of the same systemic disorder, with a shared aetiological factor being endothelial dysfunction. Moreover, the penile arteries have a smaller size compared with coronary arteries; thus, for the same level of arteriopathy, a more significant blood flow reduction will occur in erectile tissue compared with coronary circulation. As a result, ED often precedes CVD by 2–5 years, and its diagnosis offers a time window for cardiovascular risk mitigation. Growing evidence suggests, in fact, that patients presenting with ED should be investigated for CVD even if they have no symptoms. Early detection could facilitate prompt intervention and a reduction in long-term complications. In this review, we provide an overview of the pathogenetic mechanisms behind arteriogenic ED and CVD, focusing on the role of endothelial dysfunction as the common denominator of the two disorders. Developed algorithms that may help identify those patients complaining of ED who should undergo detailed cardiologic assessment and receive intensive treatment for risk factors are also analyzed.

Abstract. The quantification of CO2 emissions from anthropogenic land use and land use change (eLUC) is essential to understand the drivers of the atmospheric CO2 increase and to inform climate change mitigation policy. Reported values in synthesis reports are commonly derived from different approaches (observation-driven bookkeeping and process-modelling) but recent work has emphasized that inconsistencies between methods may imply substantial differences in eLUC estimates. However, a consistent quantification is lacking and no concise modelling protocol for the separation of primary and secondary components of eLUC has been established. Here, we review differences of eLUC quantification methods and apply an Earth System Model (ESM) of Intermediate Complexity to quantify them. We find that the magnitude of effects due to merely conceptual differences between ESM and offline vegetation model-based quantifications is ~ 20 % for today. Under a future business-as-usual scenario, differences tend to increase further due to slowing land conversion rates and an increasing impact of altered environmental conditions on land-atmosphere fluxes. We establish how coupled Earth System Models may be applied to separate secondary component fluxes of eLUC arising from the replacement of potential C sinks/sources and the land use feedback and show that secondary fluxes derived from offline vegetation models are conceptually and quantitatively not identical to either, nor their sum. Therefore, we argue that synthesis studies should resort to the "least common denominator" of different methods, following the bookkeeping approach where only primary land use emissions are quantified under the assumption of constant environmental boundary conditions.

Objectives Some studies suggested more COVID-19-associated hospitalizations among racial and ethnic minorities. To inform public health practice, the COVID-19-associated Hospitalization Surveillance Network (COVID-NET) quantified associations between race/ethnicity, census tract socioeconomic indicators, and COVID-19-associated hospitalization rates. Methods Using data from COVID-NET population-based surveillance reported during March 1–April 30, 2020 along with socioeconomic and denominator data from the US Census Bureau, we calculated COVID-19-associated hospitalization rates by racial/ethnic and census tract-level socioeconomic strata. Results Among 16,000 COVID-19-associated hospitalizations, 34.8% occurred among non-Hispanic White (White) persons, 36.3% among non-Hispanic Black (Black) persons, and 18.2% among Hispanic or Latino (Hispanic) persons. Age-adjusted COVID-19-associated hospitalization rate were 151.6 (95% Confidence Interval (CI): 147.1–156.1) in census tracts with >15.2%–83.2% of persons living below the federal poverty level (high-poverty census tracts) and 75.5 (95% CI: 72.9–78.1) in census tracts with 0%–4.9% of persons living below the federal poverty level (low-poverty census tracts). Among White, Black, and Hispanic persons living in high-poverty census tracts, age-adjusted hospitalization rates were 120.3 (95% CI: 112.3–128.2), 252.2 (95% CI: 241.4–263.0), and 341.1 (95% CI: 317.3–365.0), respectively, compared with 58.2 (95% CI: 55.4–61.1), 304.0 (95%: 282.4–325.6), and 540.3 (95% CI: 477.0–603.6), respectively, in low-poverty census tracts. Conclusions Overall, COVID-19-associated hospitalization rates were highest in high-poverty census tracts, but rates among Black and Hispanic persons were high regardless of poverty level. Public health practitioners must ensure mitigation measures and vaccination campaigns address needs of racial/ethnic minority groups and people living in high-poverty census tracts.

Mitigating climate change demands rapid reductions of greenhouse gas emissions from the construction and operation of buildings. As the design and construction industry improves tools and techniques for adding up buildings’ contributions to greenhouse gas emissions it must also consider and critique the methods used to normalize these data for analysis: how to divide them. Using Life Cycle Assessment methods, we accounted for the lifetime global warming potential of four case study buildings, each endemic of a primary structural material: steel, concrete, masonry, and mass timber. To improve the critical understanding of these denominators role in comparisons and decisions, we normalized the absolute totals using spatial (kgCO2eq/m2), temporal (kgCO2eq/year), and human (kgCO2eq/person) dimensions. The expanded analysis and visualization of lifetime carbon using novel metrics more closely associates these impacts with buildings’ purpose to shelter people over time. Attributing emissions to people, rather than buildings offers a meaningful and nuanced basis for comparison, for example, normalizing based on occupants shows that as the density increases, carbon intensity per person declines. Attending to the spatial demands of use, dividing emissions by net rather than gross area means emissions intensity decreases as building systems become more spatially efficient, while simultaneously increasing the potential occupant density. In long-lived buildings, the temporal carbon intensity (per year, or per generation) declines with age, and the time value of carbon suggests that future emissions reductions may be worth less than the present emissions to achieve them compared to even the least carbon-intensive new construction, thus emphasizing the urgent need for adaptation of existing buildings. A critical reassessment of the denominators used to normalize emissions complicates short-term considerations of life cycle emissions and militates for an architecture of persistence: designed for human use and reuse, for adaptation and maintenance.

Full textAbstract:
This paper focuses on the safety aspect of passenger trains approaching a terminal station with a bumper block/post. As evidenced by the recent collision of a commuter train at Hoboken terminal on September 29, 2016, the consequences of a collision with a bumper post could be catastrophic, however, railroads can take preventative measures to reduce the element of risk. Case studies obtained from the National Transportation Safety Board (NTSB) involving similar bumper block accidents are analyzed to identify any potential common denominator. The objective of this paper is to comprehensively present the various mitigation techniques that railroads can adopt to safeguard their systems against these types of accidents. Although some of the mitigation techniques presented in the paper may already be known in the industry generically, their application to specifically mitigating the hazard of bumper collisions is a novel attempt to focus systematically on this topic. Examples of mitigation techniques discussed here in include speed restricting devices, driver alerted features, bumper blocks with more impact tolerance, and organizational safety culture. The effect of newer technologies such as PTC (in USA only) and CBTC towards mitigating this hazard as well as the unique constraints presented at terminal stations is also assessed.

Full textAbstract:
On 30 June 2013, nineteen Prescott FD, Granite Mountain Hot Shots, a quasi-military Wildland Fire Crew, died on the Yarnell Hill Fire in Arizona. This tragic Arizona State Forestry (ASF) wildfire was “investigated” by a USDA US Forest Service-funded Serious Accident Investigation Team (SAIT). Their alleged "factual" report (SAIR) concluded they "found no indication of negligence, reckless actions, or violations of policy or protocol." Stated in the positive - they did everything right and yet nineteen men perished. This no blame, no-fault conclusion clearly defies logic and reason. Both USFS and BLM training publications mirror each other: "If firefighters follow the Standard Firefighting Orders and are alerted to the 18 Watch Out Situations, much of the risk of firefighting can be reduced." In 2001 and 2002, former USFS Fire Director Jerry Williams fully supported that joint assertion: “The Ten Standard Firefighting Orders must be firm rules of engagement. … They are the result of hard-learned lessons. Compromis¬ing one or more of them is a common denominator of all tragedy fires. … [where] the Fire Orders were ignored, overlooked, or otherwise compromised.” “Entrapment avoid¬ance must be our primary emphasis and our measure of professional operational success. We must embrace the rules of engagement as a way of doing business - as a professional standard. ... because we owe it to one another. The Fire Orders must become a shared obligation, where the leader’s situational awareness depends on participation by the entire crew and where the crew’s participation is tempered with respect for the leader’s responsibility ..." The SAIT states: "The 10 Standard Firefighting Orders and 18 Watch Out Situations ... [are] the foundation of training in fire suppression operations, ... but they require judgment in application. These principles, ... outline the [SAIT’s] perspective regarding the use and consideration of the 10 and 18 in [the SAIR]." This contradicts the GMHS aftermath.Additionally, other Agency video training sources have made light of this serious subject. “Visualizing The Ten and Eighteen - With Humor” (2004) Kathy Murphy; “WFSTAR: Fire Orders” (2018); and the Wildland Fire LLC - “Honor the Fallen” (2018). In this video, the Standard Fire Orders are denigrated by the USFS Apprenticeship Program Manager: “the truth is that we try to put it into these little boxes in these rules and the 10 and 18 that cannot, they’re not gonna keep us safe, that’s been proven time and time again, we can’t follow our own rule, you know, these rules whatever they are” and states they need to have “luck decision conversation[s],” concluding with “it was good … until it wasn’t.” Did these, and coaching from others, result in the third-year GMHS sole survivor McDonough’s SAIT assertion that Fire Order Ten regarding safely fighting fire, was “hillbilly” and “old”? The documented YH Fire and GMHS tragedy is inaccurate. Indeed, knowing, recognizing, and applying the 10 and 18, and mitigating any Watchout Situations are responsible for saving tens of thousands of WF lives every year! There are no documented cases revealing otherwise.

Full textAbstract:
The electrical disturbance in Forsmark 2006 [3] led to increased attention being paid to the power supplies of nuclear power plants and their role in safety system reliability, both nationally and internationally. Since then numerous disturbances similar in nature have occurred in the electrical power supply which raises questions whether best available technology (BAT) has been utilised in the design and analysis of the electrical power supply of the safety functions of nuclear facilities. On repeated occasions this type of disturbances has had an impact on redundant parts of several safety systems due to functional dependencies between these. The frequency of these occurrences has been unexpected. The Swedish Radiation Safety Authority (SSM) has decided to write this document to clarify the regulators position on this issue. The document is also intended to support SSM:s assessments and evaluations of the Licensees efforts regarding degraded power supplies. An assessment of nuclear power plant electrical power systems is necessary in the light of the past years’ operational experience [1–7], where disturbances in the electrical power supply on repeated occasions have caused a power supply with degradation severe enough to challenge plant safety. As the potential consequences of such a degraded power supply can be severe it must be proven that the frequency of such occurrences is tolerably low. Furthermore, it is important to consider experiences from known situations with degraded power supplies, to enable a reasonable approach to identify and take counter-measures based on the root-cause and ensure utilisation of best available technology. A sufficient approach to enable prevention, protection and mitigation against this type of disturbances has been difficult to identify. Actual events and conditions causing a degraded power supply have often been complex in nature and difficult to anticipate, wherefore events and conditions which has not yet occurred are difficult to foresee. For this reason it is deemed most effective to identify and implement proportional measures that enhances the independence of the power supplies, such that a degraded power supply with a higher reliability is prevented from propagating to multiple parts of the safety systems. In this memorandum, SSM describes a state-based approach to analysing electrical power system functionality in different states of degraded power supply. The approach is intended to identify potential design weaknesses and measures to enhance robustness. Such an approach is viewed as more favourable in facilitating the identification of such measures, which may otherwise be neglected due to an estimated low frequency of occurrence, or missed due to incomplete identification of possible events and conditions. Furthermore this document describes how an assessment of electrical power system design can be performed, where the lowest common denominator from operational experience e.g. [1–7] is identified and counteracted. Actual occurrences of degraded power supplies, which all have been “unknown during the event identification process” but “well-known electrical phenomena”, can be described as unidentified degrading conductive disturbances.
