Abstract Sifting through vast textual data and summarizing key information from electronic health records (EHR) imposes a substantial burden on how clinicians allocate their time. Although large language models (LLMs) have shown immense promise in natural processing (NLP) tasks, efficacy diverse range of clinical summarization tasks has not yet been rigorously demonstrated. In this work, we apply domain adaptation methods to eight LLMs, spanning six datasets four distinct tasks: radiology...
In the 1960s many American cities experienced violent, race-related civil disturbances. This article examines census data from 1950 to 1980 measure riots' impact on value of central-city residential property, and especially black-owned property. Both OLS IV estimates indicate that riots depressed median property between 1960 1970, with little or no rebound in 1970s. Census tract for a small number suggest relative losses population tracts were directly affected by compared other same cities.
The onset of World War I spurred the “Great Migration” African Americans from US South, arguably most important internal migration in history. We create a new panel dataset more than 5,000 men matched 1910 to 1930 census manuscripts address three interconnected questions: To what extent was there selection into migration? How large were migrants’ gains? Did narrow racial gap economic status? find evidence positive selection, but gains large. A substantial amount black-white convergence this...
We study the local effects of a federal program that helped cities clear areas for redevelopment, rehabilitate structures, complete city plans, and enforce building codes. use an instrumental variable strategy to estimate program's on city-level measures income, property values, employment poverty rates, population. The estimated population are positive economically significant. They not driven by changes in demographic composition. Estimated reduction but imprecise. results consistent with...
It is unclear whether asthma and its allergic phenotype are risk factors for hospitalization or severe disease from SARS-CoV-2. All patients over 28 days old testing positive SARS-CoV-2 between March 1 September 30, 2020, were retrospectively identified characterized through electronic analysis at Stanford. A sub-cohort was followed prospectively to evaluate long-term COVID-19 symptoms. 168,190 underwent testing, 6,976 (4.15%) tested positive. In a multivariate analysis, not an independent...
We document the intergenerational mobility of Black and White American men from 1880 through 2000 by building new historical datasets for late nineteenth early twentieth century combining them with modern data to cover middle century. find large disparities in mobility, children having far better chances escaping bottom distribution than every generation. This gap was more important proximately determining each generation's racial initial parents' economic status. (JEL D31, J15, J62, N31, N32)
We present new estimates of home ownership for black and white households from 1870 to 2007. Black increased by 46 percentage points, whereas 20 points. Remarkably, 25 the 26 point narrowing occurred between 1910. Part this early convergence is accounted falling due movement out agriculture, but most post-emancipation gains among blacks. After 1910, ownership, racial gap barely changed. discuss influence residential segregation, public policy, permanent income on gap.
Extra-Amazonian autochthonous Plasmodium vivax infections have been reported in mountainous regions surrounded by the Atlantic Forest Espírito Santo state, Brazil. Sixty-five patients and 1,777 residents were surveyed between April 2001 March 2004. Laboratory methods included thin thick smears, multiplex-PCR, immunofluorescent assay (IFA) against P. malariae crude blood-stage antigens enzyme-linked immunosorbent (ELISA) for antibodies vivax-complex (P. variants) malariae/Plasmodium...
We construct datasets of linked census records to study internal migrants' selection and destination choices during the first decades “Great Migration” (1910–1930). both whites blacks intra- inter-regional migration. While there is some evidence positive selection, degree was small participation in migration widespread. Differences background, including initial location, cannot account for racial differences choices. Blacks were similarly responsive pre-existing migrant stocks from their...
BACKGROUNDProlonged symptoms after SARS-CoV-2 infection are well documented. However, which factors influence development of long-term symptoms, how vary across ethnic groups, and whether correlate with biomarkers points that remain elusive.METHODSAdult reverse transcription PCR-positive (RT-PCR-positive) patients were recruited at Stanford from March 2020 to February 2021. Study participants seen for in-person visits diagnosis every 1-3 months up 1 year diagnosis; they completed symptom...
Whether immigrants advance in labor markets during their lifetimes relative to natives is a fundamental question the economics of immigration. We examine linked census records for five cohorts spanning 1850–1940, when immigration United States was at its peak. find U-shaped pattern assimilation: were “catching up” early and later cohorts, but not between. This change due shifts immigrants’ source countries. Instead, it rooted men’s early-career occupations, which we associate with structural...
Analyzing vast textual data and summarizing key information from electronic health records imposes a substantial burden on how clinicians allocate their time. Although large language models (LLMs) have shown promise in natural processing (NLP), effectiveness diverse range of clinical summarization tasks remains unproven. In this study, we apply adaptation methods to eight LLMs, spanning four distinct tasks: radiology reports, patient questions, progress notes, doctor-patient dialogue....
Nicotinamide adenine dinucleotide (phosphate) reduced:quinone oxidoreductase (NQO1) and glutathione S-transferase (GST) M1 are phase II enzymes important in response to oxidative stress, such as occurs during exposure ozone. We examined the relationship between functionally significant polymorphisms NQO1 (Pro187Ser) GSTM1 (homozygous deletion) asthma risk children with high lifetime enrolled from allergy referral clinic at a public pediatric hospital Mexico City, together their parents....
We examine the hypothesis that advances in household technology caused US baby boom, and we find no support for this claim. Advances occurred before while fertility declined. From 1940 to 1960, levels/changes county-level appliance ownership electrification negatively predict rates. Exposure electricity early adulthood children-ever-born are correlated relevant cohorts. The Amish, who used modern technologies much less than other households, experienced a coincident boom. This evidence can...
Valvular and vascular calcification are common causes of cardiovascular morbidity mortality. Developing effective treatments requires understanding the molecular underpinnings these processes. Shear stress is thought to play a role in inhibiting calcification. Furthermore, NOTCH1 regulates valvular endothelium, human mutations can cause calcific aortic valve disease. Here, we determined genome-wide impact altering shear NOTCH signaling on endothelium. mRNA-sequencing primary endothelial...
ABSTRACT The immunogenicity and protective efficacy of four versions recombinant C-terminal 19-kDa epidermal growth factor-like region the major surface protein 1 (rMSP1 19 ) Plasmodium falciparum was studied in Aotus monkeys. Vaccination with each rMSP1 constructs elicited high levels antibodies to MSP1 but only one construct, fragment expressed as a secreted fusion from Saccharomyces cerevisiae (yP30P2MSP1 ), induced degree immunity nancymai against lethal P. challenge. Protective...
