The Correlation Between Neonatal Intensive Care Unit Safety Culture And Quality Of Care, Jochen Profit, Paul J Sharek, Xin Cui, Courtney C Nisbet, Eric J Thomas, Daniel S Tawfik, Henry C Lee, David Draper, J Bryan Sexton

Journal Articles

OBJECTIVES: Key validated clinical metrics are being used individually and in aggregate (Baby-MONITOR) to monitor the performance of neonatal intensive care units (NICUs). The degree to which perceptions of key components of safety culture, safety climate, and teamwork are related to aspects of NICU quality of care is poorly understood. The objective of this study was to test whether NICU performance on key clinical metrics correlates with caregiver perceptions of safety culture.

STUDY DESIGN: Cross-sectional study of 6253 very low-birth-weight infants in 44 NICUs. We measured clinical quality via the Baby-MONITOR and its nine risk-adjusted and standardized subcomponents (antenatal corticosteroids, …

Decomposing Loss Aversion From Gaze Allocation And Pupil Dilation, Feng Sheng, Arjun Ramakrishnan, Darsol Seok, Wenjia Joyce Zhao, Samuel Thelaus, Puti Cen, Michael Louis Platt

Journal Articles

Loss-averse decisions, in which one avoids losses at the expense of gains, are highly prevalent. However, the underlying mechanisms remain controversial. The prevailing account highlights a valuation bias that overweighs losses relative to gains, but an alternative view stresses a response bias to avoid choices involving potential losses. Here we couple a computational process model with eye-tracking and pupillometry to develop a physiologically grounded framework for the decision process leading to accepting or rejecting gambles with equal odds of winning and losing money. Overall, loss-averse decisions were accompanied by preferential gaze toward losses and increased pupil dilation for accepting gambles. …

Examining Measurement Reactivity In Daily Diary Data On Substance Use: Results From A Randomized Experiment, Anne Buu, Songshan Yang, Runze Li, Marc A Zimmerman, Rebecca M Cunningham, Maureen A Walton

Journal Articles

The debate about whether measurement reactivity exists in daily diary research on substance use is still unsettled due to the issues of study design and statistical methodology. This study proposes a time-varying effect model (TVEM) that characterizes the trajectory of substance use behaviors with nonparametric functions determined by the data rather than imposes presumed parametric functions. It also allows researchers to investigate the effect of measurement reactivity on not only the likelihood of using substances but also the amount of substance use. The TVEM was applied to analyze diary data on alcohol and marijuana use collected from an experiment, which …

De Novo Mutations Across 1,465 Diverse Genomes Reveal Mutational Insights And Reductions In The Amish Founder Population, Michael D Kessler, Douglas P Loesch, James A Perry, Nancy L Heard-Costa, Daniel Taliun, Brian E Cade, Heming Wang, Michelle Daya, John Ziniti, Soma Datta, Juan C Celedón, Manuel E Soto-Quiros, Lydiana Avila, Scott T Weiss, Kathleen Barnes, Susan S Redline, Ramachandran S Vasan, Andrew D Johnson, Rasika A Mathias, Ryan Hernandez, James G Wilson, Deborah A Nickerson, Goncalo Abecasis, Sharon R Browning, Sebastian Zöllner, Jeffrey R O'Connell, Braxton D Mitchell, Timothy D O'Connor

Journal Articles

De novo mutations (DNMs), or mutations that appear in an individual despite not being seen in their parents, are an important source of genetic variation whose impact is relevant to studies of human evolution, genetics, and disease. Utilizing high-coverage whole-genome sequencing data as part of the Trans-Omics for Precision Medicine (TOPMed) Program, we called 93,325 single-nucleotide DNMs across 1,465 trios from an array of diverse human populations, and used them to directly estimate and analyze DNM counts, rates, and spectra. We find a significant positive correlation between local recombination rate and local DNM rate, and that DNM rate explains a …

Clinical Mortality In A Large Covid-19 Cohort: Observational Study., M. Jarrett, S. Schultz, J. Lyall, J. Wang, L. Stier, M. De Geronimo, K. Nelson

Journal Articles

BACKGROUND: Northwell Health, an integrated health system in New York, has treated more than 15,000 inpatients with COVID-19 at the US epicenter of the SARS-CoV-2 pandemic.

OBJECTIVE: We describe the demographic characteristics of patients who died of COVID-19, observation of frequent rapid response team/cardiac arrest (RRT/CA) calls for non-intensive care unit (ICU) patients, and factors that contributed to RRT/CA calls.

METHODS: A team of registered nurses reviewed the medical records of inpatients who tested positive for SARS-CoV-2 via polymerase chain reaction before or on admission and who died between March 13 (first Northwell Health inpatient expiration) and April 30, 2020, …

Distinct Profiles Of Specialized Pro-Resolving Lipid Mediators And Corresponding Receptor Gene Expression In Periodontal Inflammation, Brittney Ferguson, Nishantha R Bokka, Krishna Rao Maddipati, Srinivas Ayilavarapu, Robin Weltman, Lisha Zhu, Wanqi Chen, W Jim Zheng, Nikola Angelov, Thomas E Van Dyke, Chun-Teh Lee

Journal Articles

Polyunsaturated fatty acid-derived specialized pro-resolving lipid mediators (SPMs) play an important role in modulating inflammation. The aim of the study was to compare profiles of SPMs, SPM related lipid mediators and SPM receptor gene expression in gingiva of subjects with periodontitis to healthy controls. A total of 28 subjects were included; 13 periodontally healthy and 15 periodontitis before or after non-surgical periodontal therapy. Gingival tissues were collected from two representative posterior teeth prior to and 8 weeks after scaling and root planning; only once in the healthy group. Lipid mediator-SPM metabololipidomics was performed to identify metabolites in gingiva. qRT-PCR was …

Systemic Th17 Response In The Presence Of Periodontal Inflammation, Lina J Suárez, Daniel E Vargas, Adriana Rodríguez, Roger M Arce, Nelly S Roa

Journal Articles

BACKGROUND: The relationship between periodontitis and the pathogenesis of other inflammatory diseases, such as diabetes, rheumatoid arthritis and obesity has been an important topic of study in recent decades. The Th17 pathway plays a significant role in how local inflammation can influence systemic inflammation in the absence of systemic pathology.

OBJECTIVE: To determine Th17 biased-cells in systemically healthy patients in the presence of generalized chronic periodontitis.

METHODOLOGY: A total of 28 patients were recruited without systemic inflammatory pathology, which was determined by clinical history, the Health Assessment Questionnaire (HAQ) and rheumatoid factor detection. Of these patients, 13 were diagnosed as …
