As COVID-19 continues to spread globally, monitoring the disease at different scales is critical support public health decision making. Surveillance for SARS-CoV-2 RNA in wastewater can supplement surveillance based on diagnostic testing. In this paper, we report results of wastewater-based Emory University campus that included routine sampling sewage from a hospital building, an isolation/quarantine and 21 student residence halls between July 13th, 2020 March 14th, 2021. We examined...
This study examines the feasibility of rapidly training and fit testing health care workers to use elastomeric half-mask respirators (EHMRs), widely used in construction manufacturing, as an alternative N95 during periods shortage.
Abstract High ambient temperature poses significant health risk globally. However, the relative importance of different exposure pathways leading to risks remains unclear. For 9 US states during 2016–2018, ED visit records for heat exhaustion and stroke (HEAT), fluid electrolyte imbalance (FEI), volume depletion (VD), acute kidney injury (AKI) were identified via diagnosis codes. Co‐diagnosed Y92 subcodes (Y codes) used categorize patient's location at time or condition. Logistic regressions...
Bioaerosol samples were collected in an airborne infection isolation room, bathroom, and anteroom of a ventilated patient with coronavirus disease 2019. Twenty-eight negative for severe acute respiratory syndrome 2 (SARS-CoV-2) nucleic acid, possibly due to the being on closed-circuit ventilator or efficiency air exchanges room.
Short-term temperature variability, defined as the range occurring within a short time span at given location, appears to be increasing with climate change. Such variation in may influence acute health outcomes, especially cardiovascular diseases (CVD). Most research on variability has focused impact of within-day diurnal range, but over period few days also health-relevant through its thermoregulation and autonomic cardiac functioning. To address this gap, study utilized database emergency...
Previous research has shown that rooms of patients with coronavirus disease 2019 (COVID-19) present the potential for healthcare-associated transmission through aerosols containing severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). However, data on presence these outside patient are limited. We investigated whether virus-containing were in nursing stations and room hallways a referral center critically ill COVID-19 patients.Eight National Institute Occupational Safety Health BC...
Climate change is an important driver of migration, but little research exists on whether migrant communities in the U.S. identify climate change-related factors as reasons for migrating. In 2021, we conducted a multidisciplinary, collaborative project to better understand nexus and immigrant health Atlanta area. This paper presents one arm this collaboration that explored both role decisions immigrate Georgia ways intersects with other possible drivers migration. First generation migrants...
Cloth masks are a tool for controlling community transmission during pandemics, as well other outbreak situations. However, cloth vary in their designs, and the consequences of this variability effectiveness source control have received little attention, particularly terms user discomfort problematic mask-wearing behaviors. In present studies, common design parameters were systematically varied to ascertain effect(s) on subjective frequency behaviors, which detract from control. The type...
Climate change has negatively impacted the agricultural and socioeconomic infrastructure of Latin American Caribbean (LAC) countries leading to conditions that promote human migration. It also led emergence reemergence infectious diseases. This pilot study aimed identify climate-related drivers migration describe burden climate-sensitive neglected tropical diseases (NTD) in immigrants living Atlanta, Georgia, USA. First generation from LAC Atlanta-metro area were recruited between May...
Background: Reusable elastomeric half-mask respirators (EHMR) are an alternative to address shortages of disposable respirators. While respirator discomfort has been noted as a barrier adherence wearing N95 filtering facepiece (FFR) among health care personnel (HCP), few have examined EHMR comfort while providing patient care, which was the purpose this study. Method: Among cohort 183 HCP, we prospectively how HCP rated tolerability using Respirator Comfort, Wearing Experience, and Function...
During shortages, elastomeric half-mask respirators (EHMRs) are an alternative to reusing N95 filtering facepiece but require between-use disinfection. The objectives of this study were (a) measure microbial reductions on EHMR surfaces under laboratory conditions by a standardized procedure using wipes impregnated with health care disinfectants and (b) EHMRs disinfected volunteer providers.
A wide range of household secondary infection rates has been reported, and the role children in population transmission dynamics for SARS-CoV-2 remains ill-defined. We sought to better understand early pandemic.
Research on temperature and respiratory hospitalizations is lacking in the southeastern U.S. where cold weather relatively rare. This retrospective study examined association between waves pneumonia influenza (P&I) emergency department (ED) visits three metro-Atlanta hospitals.We used a case-crossover design, restricting data to cooler seasons of 2009-2019, determine whether influenced ED hospitalizations. analysis considered effects by race/ethnicity, age, sex, severity comorbidities. We...
Ecological theories suggest that environmental, social, and individual factors interact to cause obesity. Yet, many analytic techniques, such as multilevel modeling, require manual specification of interacting factors, making them inept in their ability search for interactions. This paper shows evidence an explainable artificial intelligence approach, commonly employed genomics research, can address this problem. The method entails using random intersection trees decode interactions learned...
Evidence varies as to how far aerosols spread from individuals infected with SARS-CoV-2 in hospital rooms. We investigated the presence of containing inside dedicated COVID-19 patient Three National Institute for Occupational Safety and Health BC 251 two-stage cyclone samplers were set up each room a six-hour sampling period. Samplers place on tripods, which held two at various heights above floor. Extracted samples underwent reverse transcription polymerase chain reaction selected gene...
Background: Recent cases of hospital-acquired (HA) aspergillosis on our Trauma Service raised the question whether this represented an outbreak or just increased case identification. Patients and Methods: After Institutional Review Board approval, we performed a retrospective analysis all 117 patients with positive pulmonary Aspergillus cultures at Grand Strand Medical Center from 2010 through 2016. The diagnosis community-acquired (CA) invasive (IPA) was determined when were admitted...
Migration from Latin America to the US has been increasing over past few decades. Migrants may experience structural and environmental vulnerabilities that increase their risk for negative impacts of climate change upon resettlement. This pilot study examined these determinants health American immigrants in Atlanta. Between May December 2021, were recruited complete a questionnaire, with subset completing an in-depth interview. Questionnaire results analyzed descriptively, interview...
Abstract Objective: Understanding the cognitive determinants of healthcare worker (HCW) behavior is important for improving use infection prevention and control (IPC) practices. Given a patient requiring only standard precautions, we examined dimensions along which different populations HCWs cognitively organize care tasks (ie, their mental models). Design: read description then rated similarities 25 from an perspective. Using multidimensional scaling, identified characteristics tasks)...
Reflexive lattice polytopes play a key role in combinatorics, algebraic geometry, physics, and other areas. One important class of are simplices defining weighted projective spaces. We investigate the question when reflexive space simplex has integer decomposition property. provide complete classification having property for case there at most three distinct non-unit weights, conjecture general an arbitrary number weights. Further, any $m\geq 1$, we define $m$-th stabilization, simplex....
