How was research for this document conducted? Who participated?

“Since asthma surveillance data were not available at the census tract level for most of Louisiana, we estimated asthma burden using the inpatient discharge data available through LDH.”  (4)

“Case counts are not provided for CTs with a 2018 population of less than 800 to safeguard privacy.” (4)

“To minimize the need for suppression, inpatient discharge data was aggregated for the three most recent years available (2017–2019) and average annual crude rates were calculated for cases where asthma (ICD-10 code J45) was the primary diagnosis, as well as where asthma was any diagnosis.” (4)

“Spearman’s Rank Correlation was utilized to analyze the correlation between various social and environmental vulnerability factors, COVID-19 incidence, and the measures of asthma risk by CT.” (4)

 

“This was performed by first ranking the values in each dataset using RANK.AVG function in MS Excel 2016, followed by applying the PEARSON function to compare two datasets. Significance was set at alpha less than 0.05 (α < 0.05), with degrees of freedom (df) equal to two less than the total number of data points represented in both datasets” (4)

The research team works for the Section of Environmental Epidemiology and Toxicology, Office of Public Health, Louisiana Department of Health in Baton Rouge. Team members included Arundhati Bakshi; Shanon Soileau; Collete Stewart; Kate Friedman; Collete Maser; Alexis Williams; Kathleen Aubin; and Alicia Van Doren. 

How are the links between environmental conditions and health articulated?

“Currently, much of the environmental focus of the pandemic remains on PM2.5 levels; however, we noted that higher levels of ozone was consistently associated with higher incidence rates of COVID-19, and it was the only environmental factor that appeared to have an additive effect over SVI on COVID-19 incidence (Fig 1).” (11)

“Specifically, our data show a moderately strong positive correlation between SVI due to minority status/language barrier and three health data variables: asthma hospitalization; estimated asthma prevalence; and cumulative COVID-19 incidence at 3 months (Table 2). Interestingly, SVI measures were either negatively or not significantly correlated COVID-19 incidence at the 9-and 12-month time points, indicating that social vulnerability factors may have played a greater role in COVID-19 spread early in the pandemic, but may have been of diminishing importance as the pandemic wore on (Fig 1 and Table 2).” (9)

What forms of evidence and expertise are used in the document?

margauxf

This document uses data resources from the Center for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR), the Environmental Protection Agency (EPA), and the Louisiana Department of Health (LDH).

These data resources include the Social Vulnerability Index (2018 - CDC/ATSDR), the NATA Respiratory Hazard Index (EPA 2014), PM2.5level (average annual concentration in ug/m3, EPA 2016), ozone level (summer seasonal average of daily maximum 8-hour concentration in air in parts per billion, EPA 2016), indoor mold concerns reported to IEQES program (average annual number of calls, LDH 2017-2019), cumulative COVID-19 incidence rate at 3-, 6-, 9- and 12-month increments (LDH March 2020 - March 2021), asthma hospitalization (average annual crude rate, where asthma was a primary diagnosis among hospitalization cases, LDH 2017-2019), and estimated asthma prevalence (average annual crude rate, where asthma was any diagnosis among hospitalization cases, LDH 2017-2019).

Main argument, narrative and effect

margauxf

The authors offer a review of themes within occupational health and environmental public health surveillance over the past decade. In reviewing the history of public health surveillance, the authors highlight key acts of Congress in the 1970s that have made the development of “modern” occupational health and environmental health surveillance possible—but which also failed to develop into a cohesive and well-connected data management systems across federal agencies. Separate agencies were tasked with different data collection, management and intervention tasks in ways that fragmented the surveillance system to the point of ineffectiveness.

The authors argue that effective surveillance for occupational and environmental health demands development of a clear purpose for collecting data and having the data available to make meaningful analysis possible. They turn to the CDC’s childhood lead prevention program to demonstrate these points.

This article presents how Newark is taking precautionary measures to help people affected by incoming Hurricane Sandy.  The city of Newark opened JFK Center as a shelter with the help of the Amercian Red Cross. The city also advised business and home owners how to prepare for the storm to avoid minimal damage to their properties. This display of precaution demonstrates how Newark is resilient to incoming storms during hurricane seasons.

Newark recommends certain safety measures before and during dangerous storms and hurricane's.  

Newark recommends to have diaster supplies handy such as: 

flashlights, batteries, first aid kit, emergency food and water, non electric can opener, medicines, cash on hand, also study shoes.

The City of Newark recommended safety measures.  

They suggest to make plans to secure your property by clearing loose and clogged rain gutters, if you can consider building a safe room, prepare emergency supply kits filled with gallons of water, food, board up windows and doors.  Trim shrubs around your house.  Have a battery operated radio and tv if possible.  Turn off propane tanks.  charge all mobile devices.

There were several forms of resilience int eh article. The Federal Emergency Management Agency (FEMA) were preparing several emergency personnel are preparing all along the coast. In addition to this, there were several shelters open, one specfically at the John F. Kennedy Recreation Center. Many of the shelters had also teamed up with Red Cross to help during the storm.

Both the Federal Emergency Management Agency (FEMA) and Red Cross helped during this natural disaster. Also, New Jersey had sent out several sotrm warning and procedures on what to do if stuck in a troubling situation during the sotrm. New Jersey also sent out shelter locations to go to if necessary. In Newark, the public safety sent out several tips and methods to prevent any internal damage, such as flooding, in housing and what to store during the super storm.

Newark recommends to have things like handy in case they are needed:

  • flashlights
  • batteries
  • a first aid kit
  • emergency food and water
  • a non electric can opener
  • medicines
  • cash

they also recommend to put these things in a room that you deem safe along with a battery operated tv/radio, charge all your electronics and turn all the propane tanks in your possession off before the storm
