Implementation of pooled saliva tests for universal screening of cCMV infection.

Congenital cytomegalovirus (cCMV) is the most common intrauterine infection, leading to neurodevelopmental disabilities. Universal newborn infant screening of cCMV has been increasingly advocated. In the absence of a high-throughput screening test, which can identify all infected newborn infants, the development of an accurate and efficient testing strategy has remained an ongoing challenge.

Two decades of changing anthropogenic mercury emissions in Australia: inventory development, trends, and atmospheric implications.

Mercury is a toxic environmental pollutant emitted into the atmosphere by both natural and anthropogenic sources. In Australia, previous estimates of anthropogenic mercury emissions differ by up to a factor of three, with existing inventories either outdated or inaccurate and several lacking Australia-specific input data. Here, we develop a twenty-year inventory of Australian anthropogenic mercury emissions spanning 2000-2019 with annual resolution.

Ehrlichiosis and anaplasmosis subcommittee report to the Tick-borne Disease Working Group.

Ehrlichioses and anaplasmosis have undergone dramatic increases in incidence, and the geographic ranges of their occurrence and vectors have also expanded. There is marked underreporting of these diseases owing to deficient physician awareness and knowledge of the illnesses as well as limited access to appropriate diagnostic tests. Human monocytic ehrlichiosis and anaplasmosis are life threatening diseases with estimated case fatality rates of 2.

COVID-19 and the Consequences of Anchoring Bias.

Suspicion of coronavirus disease in febrile patients might lead to anchoring bias, causing misdiagnosis of other infections for which epidemiologic risks are present. This bias has potentially severe consequences, illustrated by cases of human granulocytic anaplasmosis and Lyme disease in a pregnant woman and human granulocytic anaplasmosis in another person.

Impact of clinical decision support on oritavancin prescribing in the emergency department.

Background: Emergency department (ED) visits and hospitalizations from skin and soft tissue infections (SSTIs) have been on the rise and have led to an increased clinical and economic burden. Owing to their single-dose regimen, recently approved lipoglycopeptides such as oritavancin have the potential to shift the management of SSTIs from an inpatient to outpatient setting. Limited data exist regarding the use of these drugs in the ED setting.

Effects of Sea Salt Aerosol Emissions for Marine Cloud Brightening on Atmospheric Chemistry: Implications for Radiative Forcing.

Marine cloud brightening (MCB) is proposed to offset global warming by emitting sea salt aerosols to the tropical marine boundary layer, which increases aerosol and cloud albedo. Sea salt aerosol is the main source of tropospheric reactive chlorine (Cl ) and bromine (Br ). The effects of additional sea salt on atmospheric chemistry have not been explored.

Oral rapid HIV testing in the dental setting: Experiences from three dental hygiene clinics.

Background: Oral rapid HIV testing (ORHT) is implemented in the dental setting to make individuals aware of their possibly undiagnosed HIV infection. The testing process and characteristics of clients willing to receive ORHT has yet, however, to be systematically collected.

Case Description: Three dental hygiene clinics located in academic institutions implemented ORHT from March 2016 to April 2017.

A Coupled Global Atmosphere-Ocean Model for Air-Sea Exchange of Mercury: Insights into Wet Deposition and Atmospheric Redox Chemistry.

Air-sea exchange of mercury (Hg) is the largest flux between Earth system reservoirs. Global models simulate air-sea exchange based either on an atmospheric or ocean model simulation and treat the other media as a boundary condition. Here we develop a new modeling capability (NJUCPL) that couples GEOS-Chem (atmospheric model) and MITgcm (ocean model) at the native hourly model time step.

New Avenues for Antimicrobial Stewardship: The Case for Penicillin Skin Testing by Pharmacists.

It is well-appreciated that patients with documented penicillin allergies often receive broader-spectrum antibiotics. This practice has been associated with increased antimicrobial resistance and cost. In recent years, considerable efforts have been made to spread awareness on the implications of self-reported penicillin allergies.

To Assess the Success of Computerized Order Sets and Pharmacy Education Modules in Improving Antiretroviral Prescribing.

Purpose: To assess the success of order set and pharmacist training improvement (OSPTI) in improving prescription of antiretroviral therapy (ART) in a tertiary care, public, teaching hospital.

Methods: In this pre-OSPTI (January 2012 through June 2013) and post-OSPTI study (July 2013 through September 2014), an infectious disease pharmacist reviewed all patients on ART. A review of intervention data in July 2013 led to order-set changes in the hospital's computerized order entry system for frequently intervened on antiretrovirals: ritonavir, tenofovir, emtricitabine/tenofovir disoproxil fumarate (FTC/TDF), and lamivudine.

Total Mercury Released to the Environment by Human Activities.

We estimate that a cumulative total of 1540 (1060-2800) Gg (gigagrams, 10 grams or thousand tonnes) of mercury (Hg) have been released by human activities up to 2010, 73% of which was released after 1850. Of this liberated Hg, 470 Gg were emitted directly into the atmosphere, and 74% of the air emissions were elemental Hg. Cumulatively, about 1070 Gg were released to land and water bodies.

Errors in isolation of patients with infectious tuberculosis at a public teaching hospital in New York.

Background: Studies report variability in the rates and causes of isolation errors among in-patients with active tuberculosis (TB). We reviewed our experience with delays or premature discontinuation of airborne infection isolation (AII).

Methods: Medical records of patients admitted to the Bellevue Hospital Center, New York City Health & Hospitals, New York, NY, USA, between January 2006 and July 2012 with a positive respiratory culture for Mycobacterium tuberculosis were reviewed.

Observed decrease in atmospheric mercury explained by global decline in anthropogenic emissions.

Observations of elemental mercury (Hg(0)) at sites in North America and Europe show large decreases (∼ 1-2% y(-1)) from 1990 to present. Observations in background northern hemisphere air, including Mauna Loa Observatory (Hawaii) and CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) aircraft flights, show weaker decreases (<1% y(-1)). These decreases are inconsistent with current global emission inventories indicating flat or increasing emissions over that period.

Observational and modeling constraints on global anthropogenic enrichment of mercury.

Centuries of anthropogenic releases have resulted in a global legacy of mercury (Hg) contamination. Here we use a global model to quantify the impact of uncertainty in Hg atmospheric emissions and cycling on anthropogenic enrichment and discuss implications for future Hg levels. The plausibility of sensitivity simulations is evaluated against multiple independent lines of observation, including natural archives and direct measurements of present-day environmental Hg concentrations.

Historical Mercury releases from commercial products: global environmental implications.

The intentional use of mercury (Hg) in products and processes ("commercial Hg") has contributed a large and previously unquantified anthropogenic source of Hg to the global environment over the industrial era, with major implications for Hg accumulation in environmental reservoirs. We present a global inventory of commercial Hg uses and releases to the atmosphere, water, soil, and landfills from 1850 to 2010. Previous inventories of anthropogenic Hg releases have focused almost exclusively on atmospheric emissions from "byproduct" sectors (e.

Global biogeochemical implications of mercury discharges from rivers and sediment burial.

Rivers are an important source of mercury (Hg) to marine ecosystems. Based on an analysis of compiled observations, we estimate global present-day Hg discharges from rivers to ocean margins are 27 ± 13 Mmol a(-1) (5500 ± 2700 Mg a(-1)), of which 28% reaches the open ocean and the rest is deposited to ocean margin sediments. Globally, the source of Hg to the open ocean from rivers amounts to 30% of atmospheric inputs.
