Comparing complication rates between Abbott Tendril 2088 and competitive manufacturer leads: Novel real-world data approach.

Introduction: While several studies have reported on the reliability of cardiac pacing leads, there are limited comparative data on lead performance. We compared long-term performance of Abbott Tendril™ STS 2088TC (Tendril 2088) leads with competitive manufacturer (CM) pacing leads using novel real-world data analytic methods.

Methods: Medicare fee-for-service (FFS) claims and Abbott device registration databases were linked to identify patients implanted with single-chamber or dual-chamber pacemakers with the Abbott Tendril 2088 lead from January 1, 2014 to December 31, 2019 and were followed through December 31, 2021.

Examining Excess Mortality Associated With the COVID-19 Pandemic for Renters Threatened With Eviction.

Importance: Residential evictions may have increased excess mortality associated with the COVID-19 pandemic.

Objective: To estimate excess mortality associated with the COVID-19 pandemic for renters who received eviction filings (threatened renters).

Design, Setting, And Participants: This retrospective cohort study used an excess mortality framework.

Beyond Gentrification: Housing Loss, Poverty, and the Geography of Displacement.

We assess the relationship between gentrification and a key form of displacement: eviction. Drawing on over six million court cases filed in 72 of the largest metropolitan areas across the United States between 2000 and 2016, we show that most evictions occurred in low-income neighborhoods that did not gentrify. Over time, eviction rates decreased more in gentrifying neighborhoods than in comparable low-income neighborhoods.

The impacts of rent burden and eviction on mortality in the United States, 2000-2019.

Investments in stable, affordable housing may be an important tool for improving population health, especially in the context of rising costs and evictions for American renters. Still, a lack of longitudinal data linking these exposures to health outcomes has limited prior research. In this study, we use linked administrative data to estimate the associations of rent burden and eviction with all-cause mortality.

A comprehensive demographic profile of the US evicted population.

Millions of American renter households every year are threatened with eviction, an event associated with severe negative impacts on health and economic well-being. Yet we know little about the characteristics of individuals living in these households. Here, we link 38 million eviction court cases to US Census Bureau data to show that 7.

Eviction from public housing in the United States.

Neither academic researchers nor the U.S. Department of Housing and Urban Development have studied evictions from public housing in national perspective.

Estimating eviction prevalence across the United States.

SignificanceSeveral negative effects of forced displacement have been well documented, yet we lack reliable measurement of eviction risk in the national perspective. This prevents accurate estimations of the scope and geography of the problem as well as evaluations of policies to reduce housing loss. We construct a nationwide database of eviction filings in the United States.

Coralline photosynthetic physiology across a steep light gradient.

Coralline algae (CA) are globally distributed and fulfil many important roles within coastal ecosystems. In this study, photosynthetically active radiation (PAR) measured for 616 days at 2 and 10 m in a temperate subtidal kelp forest in southern New Zealand provided context to photosynthesis vs. irradiance relationships for, and pigment concentrations of, an articulated coralline alga, Arthrocardia sp.

Paediatric patients in mass casualty incidents: a comprehensive review and call to action.

The paediatric population is disproportionately affected during mass casualty incidents (MCIs). Several unique characteristics of children merit special attention during natural and man-made disasters because of their age, physiology, and vulnerability. Paediatric anaesthesiologists play a critical part of MCI care for this population, yet there is a deficit of publications within the anaesthesia literature addressing paediatric-specific MCI concerns.

The Concentrated Geography of Eviction.

Preventing eviction is a tractable, efficient way to reduce homelessness. Doing so requires understanding the precise geography of eviction. Drawing on over 660,000 eviction records across 17 cities, this study finds the geography of evictions to be durable across time.

Association of Eviction With Adverse Birth Outcomes Among Women in Georgia, 2000 to 2016.

Importance: More than 2 million families face eviction annually, a number likely to increase due to the coronavirus disease 2019 pandemic. The association of eviction with newborns' health remains to be examined.

Objective: To determine the association of eviction actions during pregnancy with birth outcomes.

Whole community estimates of macroalgal pigment concentration within two southern New Zealand kelp forests.

Light availability is a fundamental factor that controls the productivity and distribution of macroalgae and is highly variable, both spatially and temporally, in subtidal coastal systems. Our comprehension of how macroalgae respond to such variability is a significant knowledge gap that limits our understanding of how light influences the structure and productivity of these environments. Here, we examined the pigment characteristics of individual species, and for the first time the whole community, within one low-light, and one high-light kelp-forest system in southern New Zealand.

Light dose versus rate of delivery: implications for macroalgal productivity.

The role of how light is delivered over time is an area of macroalgal photosynthesis that has been overlooked but may play a significant role in controlling rates of productivity and the structure and persistence of communities. Here we present data that quantify the relative influence of total quantum dose and delivery rate on the photosynthetic productivity of five ecologically important Phaeophyceae species from southern New Zealand. Results suggested that greater net oxygen production occurs when light is delivered at a lower photon flux density (PFD) over a longer period compared to a greater PFD over a shorter period, given the same total dose.

Who gets evicted? Assessing individual, neighborhood, and network factors.

The prevalence and consequences of eviction have transformed the lived experience of urban poverty in America, yet little is known about why some families avoid eviction while others do not. Applying discrete hazard models to a unique dataset of renters, this study empirically evaluates individual, neighborhood, and social network characteristics that explain disparities in displacement from housing. Family size, job loss, neighborhood crime and eviction rates, and network disadvantage are identified as significant and robust predictors of eviction, net of missed rental payments and other relevant factors.

Forced Displacement From Rental Housing: Prevalence and Neighborhood Consequences.

Drawing on novel survey data of Milwaukee renters, this study documents the prevalence of involuntary displacement from housing and estimates its consequences for neighborhood selection. More than one in eight Milwaukee renters experienced an eviction or other kind of forced move in the previous two years. Multivariate analyses suggest that renters who experienced a forced move relocate to poorer and higher-crime neighborhoods than those who move under less-demanding circumstances.

Light Limitation within Southern New Zealand Kelp Forest Communities.

Light is the fundamental driver of primary productivity in the marine environment. Reduced light availability has the potential to alter the distribution, community composition, and productivity of key benthic primary producers, potentially reducing habitat and energy provision to coastal food webs. We compared the underwater light environment of macroalgal dominated shallow subtidal rocky reef habitats on a coastline modified by human activities with a coastline of forested catchments.

Non-additive counteraction of KCl-perturbation of lactate dehydrogenase by trimethylamine N-oxide.

Added KCl increases the apparent Michaelis constant (Km) of pyruvate for porcine muscle-type lactate dehydrogenase (100 mM KCl, 83%; 200 mM KCl, 188%). The effects of 100 mM KCl were fully reversed by 375 mM trimethylamine N-oxide (TMAO). TMAO (375-750 mM) partially reversed the effects of 200 mM KCl.
