Prejudice between triage nurses and emergency medical technicians: is it a big deal?

Acta Biomed 2021 Jul 29;92(S2):e2021026. Epub 2021 Jul 29.

Department of Biomedical Sciences for Health, University of Milan, Milano, Italy.

The transmission of information between registered nurses (RNs) and emergency medical technicians (EMTs) in triage plays a fundamental role in patient care. Despite their common purpose is to assure patients to get the best diagnostic, therapeutic and care pathway, triage RNs and EMTs hold different perspectives during the process. One aspect that has not been investigated in the international literature concerns the possible presence of prejudice, meant as a preconceived opinion capable of causing people to adopt unjust attitudes toward EMTs by triage RNs.

Examining how meta-analytic methods perform in the presence of bias: A simulation study.

Res Synth Methods 2021 Jul 30. Epub 2021 Jul 30.

Population Health Sciences, Bristol Medical School, University of Bristol.

Standard meta-analysis methods are vulnerable to bias from incomplete reporting of results (both publication and outcome reporting bias) and poor study quality. Several alternative methods have been proposed as being less vulnerable to such biases. To evaluate these claims independently we simulated study results under a broad range of conditions first with no bias, then introducing simulated publication bias, outcome reporting bias, and bias from poor study quality.

Perceptions of Spiritual Dryness in Iran During the COVID-19 Pandemic.

J Relig Health 2021 Jul 29. Epub 2021 Jul 29.

Cancer Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

This study addresses perceptions of spiritual dryness (a specific form of spiritual struggle) during the COVID-19 pandemic among Iranian Muslims (n = 362), and how these perceptions can be predicted. Spiritual dryness was perceived often to regularly by 27% and occasionally by 35%. Regression models revealed that the best predictors of spiritual dryness (SDS-7) were usage of mood-enhancing medications, loneliness/social isolation and praying as positive predictors, and being restricted in daily life concerns as negative predictor.

Cardiovascular risk assessment: The foundation of preventive cardiology.

Nathan D Wong

Am J Prev Cardiol 2020 Mar 1;1:100008. Epub 2020 May 1.

Heart Disease Prevention Program, Division of Cardiology, C240 Medical Sciences, University of California, Irvine, CA, 92697-4079, USA.

The foundation of preventive cardiology begins with knowing the patient's baseline cardiovascular disease (CVD) risk from which the patient-clinician risk discussion informs on the best ways to lower risk through lifestyle management, as well as a decision about the initiation and intensity of pharmacologic therapy. Global CVD risk assessment involves estimation of cardiovascular risk using a basic panel of risk factors. The Framingham Heart Study championed the first such risk scores, followed by others around the world. Read More
