379. Abstract For Comparison of Mandatory vs Non-Mandatory Compliance Rates For SARS-CoV-2 Testing in Grades K-12

Background Rapid testing to identify asymptomatically infected students with SARS-CoV-2 in elementary schools has been suggested as a possible method to reduce risk for in person instruction. As of August 3, 2020 (updated on January 25, 2021), California schools who obtained a waiver to conduct in-person instruction are not required to have mandatory testing for asymptomatic students, except for high contact sports which are required to undergo weekly testing. We explored the uptake of voluntary vs mandatory testing in a private waivered school. Methods Between the dates January 25, 2021 to April 16, 2021, the K-12 school superintendent sent an email to all parents outlining the voluntary testing program with a link to the on-line sign up and consent form. All students were offered weekly self-collected anterior nares BinaxNOW Rapid Antigen Test. Signed parental consent was required and tests were performed at the school. Students participating in contact sports were required to undergo testing the week a varsity game was played as a condition of participation. Data was gathered from the school administration and de-identified. Results K-5 Lower school had a school population of 448 students. Testing was offered on 8 weeks during the period of 2/15-2/19 to 4/5-4/9. 2 students (0.45%) receive screening on the week of 3/22-3/26. The other seven weeks when screening was offered 0 students received screening. 6-12 Upper school had a school population of 360 enrolled students. Testing was offered 3/8-3/12 and 3/15-3/19. The upper school had 22 students (6.11%) receive testing on the week of 3/8-3/12 and 21 students (5.83%) on the week of 3/15-3/19. Contact sports teams had 67 students on their roster. Weekly testing was offered from 3/22-3/26 to 4/12-4/16. Contact sports teams had 10 students (14.93%) receive testing on the week of 3/22-3/26, 33 students (52.24%) on the week of 4/5-4/9, and 32 students (49.25%) on the week of 4/12-4/16. Figure 1. Percent of students from each campus and sports team screened per week offered. Conclusion Voluntary SARS-CoV-2 screening was not a feasible approach for detection of asymptomatically infected individuals due to low uptake, however in the same school, mandatory testing had high uptake and would be a feasible strategy.

Overview of large building testing in Baltic countries

The objectives of this paper are to review measurements of airtightness of 2 large building groups – middle size shops, and warehouses/distribution centres. The mean air leakage rate at 50 Pa pressure difference q50 was 1.04 m3/m2h and 1.35 m3/m2h for shops and warehouses respectively. Analysis of measurement results is valuable because it allows to make a conclusion about compliance of national and corporative construction airtightness norms with actual air barrier condition on a comissioning stage. In the concluding part of the study there are suggested ways to improve air barrier such as review of construction norms, implementation of a mandatory testing and quality control of a measurement.

Elective surgeries in the “new normal” post-COVID-19 pandemic: to test or do not test?

ABSTRACT The new coronavirus (SARS-CoV-2) pandemic has been wreaking havoc all over the planet. In a precautionary measure, populations have been forced and kept under quarantine to contain the outbreak of the COVID-19 disease. The quarantine primary goal is to avoid the overload to the hospitals, which should be available for the care of COVID-19 patients. However, the virus does not have a uniform spread throughout the planet, and Brazil is no different. Although all the world’s attention is now on the COVID-19 pandemic, there is no similar pattern of spread, and other diseases are still a real problem. Given the risks of transmission between patients and healthcare providers, there is a great challenge for healthcare institutions who must balance resources to assure safe care to patients and professionals while they take care of other disease patients, and perform surgical procedures that need to be carried out. Under such circumstances, as COVID-19 can also present pre- or asymptomatic transmission, it can be challenging to identify patients who are carrying and spreading the virus. Studies and information on mandatory testing for who are candidates to undergo elective surgery are scarce. Thus, the authors have reviewed the literature, and discuss the need to test these patients under the current context.

The Effects of Legislation Mandating DNA Testing in Sexual Assault Cases: Results in Texas

Many cities and states have taken steps to identify and process all untested sexual assault kits (SAKs). Texas was one of the first states to enact such legislation—SB 1636—which created a time line for a statewide audit and mandatory testing of SAKs. A mixed-methods approach was used to assess the effects of SB 1636 at both state and local levels. The study did not detect any effect of SB 1636 on reporting, arrests, or convictions. The legislation did have a significant effect on criminal justice workloads, particularly crime laboratories.

OVERCOMING VITAMIN-D DEFICIENCY IN MALE GYMNASTS DURING PRETEEN YEARS

This paper addresses the issue of vitamin-D deficiency, which is approaching epidemic scale in the Asian countries. Lack of proper nutrition and awareness contributes to this problem. After an explanation of the mechanism of production of vitamin D, the authors list adverse effects of vitamin-D deficiency and propose mandatory testing of vitamin-D deficiency during physical examinations. The remedial measures to overcome this deficiency in the context of preteen male gymnasts include supplements, proper nutrition in the form of sun-ripe fruits and vegetables as well as guarded-graduated sun-exposure. The last two are preferred over supplements as the supplements may produce toxicity if taken in higher doses.
