Scientific Questions Being Studied

The goal of this project is to examine if social distance measurements due to Covid_19 caused stress to cancer patients compared to non-cancer patients. In particular we will use the data to examine differences by race, ethnicity, age and sex and to answer to the following questions:
In the past month, have recommendations for socially distancing caused stress for you?
Have you EVER been near someone that you know, or suspect, had COVID-19 (such as co-workers, family members, or others)?
Do you think you have had COVID-19?
We will examine all of the questions above and determine if there are differences in patients diagnosed with cancer compared to patients never diagnosed with cancer and are the differences in those question above differ by race, ethnicity, gender and age.

Project Purpose(s)

  • Disease Focused Research (cancer)
  • Social / Behavioral

Scientific Approaches

We plan to use univariate and multivariate analyses in order to examine questions about perceived stress and social distancing in cancer and non-cancer patients . The multivariate analyses will include a serries of logistic regression models where the outcomes will be perceived stress due to COVID-19 recommendations or if you think you had COVID-19 and independent covariate will include age, race, ethnicity and gender.

Anticipated Findings

We anticipate that the recommendations for social distancing will caused more stress to cancer patients compared to non-cancer patients and these relationships will vary by age, race, ethnicity and gender.

Duplicate of Spectrum of tumors after breast cancer

Interested to know what secondary or recurrent tumors developed after breast cancer and are there any demographic/behavioral/medications/medical conditions that modify/influence the risk of secondary tumors (recurrent/new tumors)

Scientific Questions Being Studied

Interested to know what secondary or recurrent tumors developed after breast cancer and are there any demographic/behavioral/medications/medical conditions that modify/influence the risk of secondary tumors (recurrent/new tumors)

Project Purpose(s)

  • Disease Focused Research (breast cancer)
  • Population Health
  • Other Purpose (Interested to know what secondary or recurrent tumors developed after breast cancer and are there any demographic/behavioral/medications/medical conditions that modify/influence the risk of secondary tumors (recurrent/new tumors))

Scientific Approaches

Plan to
Create a cohort of all participants diagnosed with breast cancer
This is case only study
For the above cohort collect all tumors that happened after diagnosis of breast cancer
Use cox model in order to determine the risk of subsequent tumors (outcome will be time to the second tumor)
Since the range of second/recurrent tumors is large we propose to look first at the spectrum of tumors and then do analyses for specific second tumors like a recurrence
Need to examine what are the factors associated with the second tumor

Anticipated Findings

We anticipate to determine guidelines for risk of second tumors after diagnosis of breast cancer

Demographic Categories of Interest

This study will not center on underrepresented populations.

Validation of Physical measurements

Validate physical measurements (height, weight, BMI) and blood measurement s between electronic health record data and physical measurements at the physical visit at the clinic. Examine those correlations by age categories, gender, race ethnicity and disease spectrum.

Scientific Questions Being Studied

Validate physical measurements (height, weight, BMI) and blood measurement s between electronic health record data and physical measurements at the physical visit at the clinic. Examine those correlations by age categories, gender, race ethnicity and disease spectrum.

Project Purpose(s)

  • Methods Development

Scientific Approaches

Create calendar period specific measurements of height, weight, blood pressure from the EHR and during the physical measurement visits and examine the correlation and agreement between the two. In addition, examine those correlations by race ethnicity, age, gender and disease status.

Anticipated Findings

How interchangeable are the EMR data with Physical measurement data during the PMB visit
Are the All of Us data coming from the EMR valid for analyses and if yes this will facilitate an expansion of use of the All of Us data

Demographic Categories of Interest

  • Race / Ethnicity
  • Age
  • Education Level
