Article Synopsis
  • Dry deposition plays a significant role in removing reactive organic carbon from the atmosphere, impacting airborne chemical reactions and transferring this carbon to other environmental systems.
  • Using aircraft measurements, researchers found that oil operations can lead to high deposition rates of organic carbon, reaching up to 100 tons per hour, with rapid lifetimes of about 4 hours that can compete with oxidation processes.
  • Traditional models for gas-phase deposition may not capture all deposited organic carbon, indicating a need to consider these deposition processes in assessing the effects on freshwater ecosystems, as they contribute significantly to the overall carbon balance compared to terrestrial sources.

Anxiety is a complex phenomenon: Its eliciting stimuli and circumstances, component behaviors, and functional consequences are only slowly coming to be understood. Here, we examine defense systems from field studies; laboratory studies focusing on experimental analyses of behavior; and, the fear conditioning literature, with a focus on the role of uncertainty in promoting an anxiety pattern that involves high rates of stimulus generalization and resistance to extinction. Respectively, these different areas provide information on evolved elicitors of defense (field studies); outline a defense system focused on obtaining information about uncertain threat (ethoexperimental analyses); and, provide a simple, well-researched, easily measured paradigm for analysis of nonassociative stress-enhanced fear conditioning (the SEFL).

Background: In patients with multivessel disease with successful primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction, the FLOWER-MI trial (Flow Evaluation to Guide Revascularization in Multivessel ST-Elevation Myocardial Infarction) showed that a fractional flow reserve (FFR)-guided strategy was not superior to an angiography-guided strategy for treatment of noninfarct-related artery lesions regarding the 1-year risk of death from any cause, myocardial infarction, or unplanned hospitalization leading to urgent revascularization. The extension phase of the trial was planned using the same primary outcome to determine whether a difference in outcomes would be observed with a longer follow-up.

Methods: In this multicenter trial, we randomly assigned patients with ST-segment-elevation myocardial infarction and multivessel disease with successful percutaneous coronary intervention of the infarct-related artery to receive complete revascularization guided by either FFR (n=586) or angiography (n=577).

Background: Endomyocardial biopsies (EMB) are recommended for the detection of acute cardiac rejection (ACR) despite limited sensitivity. We report the long-term post-transplant results of Doppler echocardiography as a noninvasive alternative of routine EMB.

Methods: Two cohorts of heart transplantation (HT) recipients were chronologically defined as follows: the Dual Monitoring Cohort (DMC) from January 1990 to December 1997 included patients who underwent routine EMB and Doppler echocardiography within 24 hours for ACR surveillance; and the "Echo-First Cohort" (EFC), including patients transplanted from January 1998 to December 2018 with Doppler echocardiography as first-line approach for ACR surveillance.

Purpose: Acute radiodermatitis (ARD) is a frequent side effect of radiotherapy, a therapeutic option for head and neck squamous cell carcinoma (HNSCC). It is responsible for pain, quality of life (QoL) impairment, and increased risk of treatment discontinuation, which may compromise the prognosis for patients. Local therapies to prevent or alleviate ARD have been proposed without providing any high level of evidence to establish recommendations.

Increasingly, interprofessional teamwork is required for the effective delivery of public health services in primary healthcare settings. Interprofessional competencies should therefore be incorporated within all health and social service education programs. Educational innovation in the development of student-led clinics (SLC) provides a unique opportunity to assess and develop such competencies.

Introduction: Australians in rural areas experience limited access to services and poorer health outcomes than residents of metropolitan areas. Nurse practitioners (NPs) were introduced in 2000 to reduce pressure on the health system, address workforce shortages and improve rural populations' access to health care services.

Objective: This scoping review sought to identify, examine and synthesise research evidence of NP practice in Australian rural primary health care services to better understand how NPs are addressing service gaps in rural areas and to identify existing gaps in our knowledge.

Article Synopsis
  • - The text evaluates the effectiveness of UV-C disinfection for high-touch surfaces in patient areas, noting varying results across different studies and room types.
  • - Out of twelve studies analyzed, UV-C showed the best results on flat surfaces, particularly in isolation rooms, while handheld and complex surfaces had reduced effectiveness.
  • - Overall, UV-C disinfection appears to outperform standard cleaning methods, but its effectiveness can vary based on the type of surface and the characteristics of the room.

Over the 30 years since IBNS was founded, a central theme of "Translation" has emerged. This reflects increasing realization that mental disorders such as anxiety and depression are extremely widespread, expensive and painful to societies and individuals across the world. The Blanchard lab has been particularly involved in attempts to understand the evolutionary and functional mechanisms underlying defensive behaviors as a focal component of these disorders.

Anxiety and depression are highly prevalent behavior disorders, particularly in women. Recent preclinical work using animal models has been suboptimal in predicting the efficacy of drugs targeted at these conditions, suggesting a potential discrepancy between such models and the human disorders. Notably female animals tend to be equal to, or less responsive than, males in these tasks.

Background: Transcatheter closure of a symptomatic prosthetic paravalvular leak (PVL) is feasible, but there is presently no conclusive evidence to show consistent efficacy. We aimed to identify predictors of clinical success after transcatheter PVL closure.

Methods: Consecutive patients referred to 24 European centers for transcatheter PVL closure in 2017 to 2019 were included in a prospective registry (, FFPP).

In general, deep neural network (DNN) pruning methods fall into two categories: 1) weight-based deterministic constraints and 2) probabilistic frameworks. While each approach has its merits and limitations, there are a set of common practical issues such as trial-and-error to analyze sensitivity and hyper-parameters to prune DNNs, which plague them both. In this work, we propose a new single-shot, fully automated pruning algorithm called slimming neural networks using adaptive connectivity scores (SNACS).

We examined the behavioural responses and Fos expression pattern of rats that were exposed to snake threats from shed snakeskin and a live snake. We differentiated the behavioural responses and the pattern of Fos expression in response to the odour cues and mild threat from a live snake. Animals exposed to the snake odour alone or to the confined snake showed a great deal of risk assessment.

Background: Communication difficulties, including hypokinetic dysarthria and swallowing difficulties (dysphagia), affect a large percentage of people diagnosed with Parkinson's disease. Onset of these symptoms has been identified in up to 78% of people with early-stage Parkinson's disease. Communication difficulties are frequently disregarded until they have a significant impact on quality of life, while the person may often be unaware of indicators of dysphagia and the associated risk of aspiration pneumonia.

The IMPACT-ICU program provides staff with tools that make difficult palliative conversations easier; introduces the "3 conversations," incorporates role-play activities, and provides for continued coaching. This program is highly relevant to the military health system, which typically lacks a specialized palliative care service. It is easily transferable to any environment to include austere locations as well as other disparate health care institutions.
