Environmental drivers impact the accumulation and diversity of antibiotic resistance in green stormwater infrastructure.

Antibiotic resistance poses an urgent public health concern, with the environment playing a crucial role in the development and dissemination of resistant bacteria. There is a growing body of research indicating that stormwater is a significant source and transport vector of resistance elements. This research sought to characterize the role of green stormwater infrastructure (GSI), designed for stormwater infiltration, in accumulating and propagating antibiotic resistance in the urban water cycle.

Review of emerging contaminants in green stormwater infrastructure: Antibiotic resistance genes, microplastics, tire wear particles, PFAS, and temperature.

Green stormwater infrastructure is a growing management approach to capturing, infiltrating, and treating runoff at the source. However, there are several emerging contaminants for which green stormwater infrastructure has not been explicitly designed to mitigate and for which removal mechanisms are not yet well defined. This is an issue, as there is a growing understanding of the impact of emerging contaminants on human and environmental health.

Integrated tire wear buildup and rainfall-runoff model to simulate tire wear particles in stormwater.

This paper presents an approach to integrate tire wear buildup and rainfall-runoff models to simulate tire wear buildup on road surfaces and its subsequent transport in stormwater runoff events. To do so, a buildup model is presented based on vehicle kilometers traveled, vehicle type, vehicle speed, and road roughness within a watershed. This buildup model was integrated into an EPA SWMM model that simulated the runoff of tire wear particles in twelve watersheds in the San Francisco, CA bay area.

Impact of traffic on air pollution in a mid-sized urban city during COVID-19 lockdowns.

In this study, we evaluated the changes in air pollutant concentrations around Milwaukee, WI, during and after lockdown due to the COVID-19 pandemic for a period of 126 days. Measurements of particulate matter (PM, PM, and PM), NH, HS, and O + NO, were made on a 74-km route of arterial and highway roads from April to August 2020 using a Sniffer 4D sensor mounted to a vehicle. Traffic volume during measurement periods were estimated from smartphone-based traffic data.

Hydrologic and water quality performance of a subsurface gravel wetland treating stormwater runoff.

Subsurface gravel wetlands are an emerging type of green infrastructure that can be used to manage stormwater through the capture and slow release of runoff. They are unique to other types of green infrastructure in that they have a distinct fully saturated gravel layer below an occasionally saturated soil layer that influences pollutant removal processes. While they have been widely applied to treat wastewater, our understanding of their efficiency in treating stormwater with variable pollutant inputs is limited.

Antibiotic resistance genes in an urban stream before and after a state fair.

The global spread of antibiotic resistance genes (ARGs) concomitant with a decrease in antibiotic effectiveness is a major public health issue. While research has demonstrated the impact of various urban sources, such as wastewater treatment plant (WWTP) effluent, stormwater runoff, and industrial discharge on ARG abundance in receiving waters, the impact of short-term gatherings such as state fairs is not comprehensively understood. The objective of this research was to explore the impact of a 2-week Wisconsin State Fair gathering - over 1.

The Charter on Professionalism for Health Care Organizations.

In 2002, the Physician Charter on Medical Professionalism was published to provide physicians with guidance for decision making in a rapidly changing environment. Feedback from physicians indicated that they were unable to fully live up to the principles in the 2002 charter partly because of their employing or affiliated health care organizations. A multistakeholder group has developed a Charter on Professionalism for Health Care Organizations, which may provide more guidance than charters for individual disciplines, given the current structure of health care delivery systems.

Perspective: Organizational professionalism: relevant competencies and behaviors.

The professionalism behaviors of physicians have been extensively discussed and defined; however, the professionalism behaviors of health care organizations have not been systemically categorized or described. Defining organizational professionalism is important because the behaviors of a health care organization may substantially impact the behaviors of physicians and others within the organization as well as other institutions and the larger community. In this article, the authors discuss the following competencies of organizational professionalism, derived from ethical values: service, respect, fairness, integrity, accountability, mindfulness, and self-motivation.

Professional medical associations and their relationships with industry: a proposal for controlling conflict of interest.

Professional medical associations (PMAs) play an essential role in defining and advancing health care standards. Their conferences, continuing medical education courses, practice guidelines, definitions of ethical norms, and public advocacy positions carry great weight with physicians and the public. Because many PMAs receive extensive funding from pharmaceutical and device companies, it is crucial that their guidelines manage both real and perceived conflict of interests.

Council ofMedical Specialty Societies: committed to continuing medical education reform.

The Council of Medical Specialty Societies (CMSS) recognizes the need for continuing medical education (CME) reform and intends to be actively engaged in that process. While recognizing that CME reform must involve many organizations, the CMSS and particularly the 23 societies that make up the CMSS are in a position to affect many of the needed changes. Of these, perhaps the most important is the need to link CME to a change in physician behavior and patient outcomes.
