The Tuberculosis Sentinel Research Network (TB-SRN) of the International epidemiology Databases to Evaluate AIDS (IeDEA): protocol for a prospective cohort study in Africa, Southeast Asia and Latin America

Introduction
Tuberculosis (TB) is a leading infectious cause of death globally. It is the most common opportunistic infection in people living with HIV, and the most common cause of their morbidity and mortality. Following TB treatment, surviving individuals may be at risk for post-TB lung disease. The TB Sentinel Research Network (TB-SRN) provides a platform for coordinated observational TB research within the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium.

Methods and analysis
This prospective, observational cohort study will assess treatment and post-treatment outcomes of pulmonary TB (microbiologically confirmed or clinically diagnosed) among 2600 people aged ≥15 years, with and without HIV coinfection, consecutively enrolled at 16 sites in 11 countries, across 6 of IeDEA’s global regions. Data regarding clinical and sociodemographic factors, mental health, health-related quality of life, pulmonary function, and laboratory and radiographic findings will be collected using standardised questionnaires and data collection tools, beginning from the initiation of TB treatment and through 12 months after the end of treatment. Data will be aggregated for proposed analyses.

Ethics and dissemination
Ethics approval was obtained at all implementing study sites, including the Vanderbilt University Medical Center Human Research Protections Programme. Participants will provide informed consent; for minors, this includes both adolescent assent and the consent of their parent or primary caregiver. Protections for vulnerable groups are included, in alignment with local standards and considerations at sites. Procedures for requesting use and analysis of TB-SRN data are publicly available. Findings from TB-SRN analyses will be shared with national TB programmes to inform TB programming and policy, and disseminated at regional and global conferences and other venues.

Assessing the feasibility of a randomised controlled trial examining the effect of hearing aids on cognitive decline in elderly individuals: a study protocol

Introduction
Hearing loss is one of the leading potentially modifiable risk factors for dementia. There is growing evidence suggesting that treating hearing loss with hearing aids could be a relatively low-cost intervention in reducing cognitive decline and the risk of dementia in the long term. However, given the current constraints of the limited evidence, it is premature to draw definitive conclusions about the effect of hearing aids on cognitive functioning. More long-term randomised studies examining this effect would be recommended. Prior to embarking on large-scale lengthy randomised controlled trials (RCTs), it is imperative to determine the viability of such studies. Therefore, the purpose of the current study is to assess the feasibility of a RCT that investigates the effect of hearing aids on cognitive functioning in elderly hearing impaired individuals.

Methods and analysis
In this randomised controlled feasibility trial, 24 individuals aged 65 years or older with mild to moderate hearing loss (≥35–

Abstract 12041: Coronary Artery Calcium and All-Cause Mortality in the Multicenter Aids Cohort Study: MACS

Circulation, Volume 148, Issue Suppl_1, Page A12041-A12041, November 6, 2023. Introduction:People living with HIV (PLWH) have more subclinical cardiovascular disease than people without HIV (PWOH), but few studies have evaluated risk for mortality based on coronary artery calcium (CAC) among this population.Purpose:This study aimed to determine the association between CAC and all-cause mortality among male PLWH and PWOH and to identify a potential interaction with HIV serostatus.Methods:The study population was derived from the MACS, a US prospective observational cohort study including male PLWH and PWOH. Participants underwent cardiac non-contrast computed tomography from July 2004 to November 2013. Men with atrial fibrillation, coronary heart disease, or coronary revascularization were excluded. Cox proportional hazards model was used to calculate adjusted hazard ratios [aHR] for all-cause mortality among men with vs. without baseline CAC (Agatston score >0) and per standard deviation (SD) increment in continuous Agatston score [log (CAC+1)], controlling for demographic and cardiac risk factors. CAC differences by HIV serostatus were evaluated using multiplicative CACхHIV interaction terms.Results:Among 1344 males (mean age 50 years, CAC prevalence 46%, 823 (61%) PLWH), we observed 110 deaths (13%) among PLWH and 41 deaths (8%) among PWOH during the follow-up period (median: 13.4 years). Among PLWH, 62% had an undetectable plasma HIV viral load, the median CD4 cell nadir was 284 cells/μL, and 17% had a history of clinical AIDS. The age-adjusted mortality rate was 13.5 (95% CI: 11.0-16.5) among PLWH and 7.8 (5.4-10.9) among PWOH per 1000 person-years. CAC presence was associated with all-cause mortality among all participants (aHR=1.47, 95% CI: 1.02-2.11, p=0.04), and among PLWH (aHR=1.61, 1.04-2.47, p=0.03). In PWOH, we found no significant association (aHR=1.27, 0.63-2.59, p=0.50), although the interaction was not significant (p= 0.49). Higher log (CAC+1) was also associated with all-cause mortality among all participants (aHR=1.37 per SD, 1.15-1.63, p

Abstract 310: Impact of “Cognitive Aids” on Responder Performance During Pediatric Code Blue Simulations – Results From Performance Improvement Project at a Tertiary Care Center in Saudi Arabia

Circulation, Volume 148, Issue Suppl_1, Page A310-A310, November 6, 2023. Introduction:Despite advances such as high-fidelity code blue simulations, pediatric In-Hospital Cardiac Arrest mortality rate has plateaued at 62% in the USA. It is expected to be higher in low-income countries. Studies show deviations from the PALS guidelines despite regular PALS training due to skills and knowledge decay. Use of simple, easily accessible resources as “Cognitive Aids”, that decrease reliance on memory during stressful events, however, has not been studied well.Aim:To evaluate impact of cognitive aids on resuscitative capabilities of code-blue responders during simulations.Method:Performance Improvement (PI) project by Pediatrics Department at King Faisal Specialist Hospital and Research Centre, Madinah, Saudi Arabia. Simulations were run by Consultant, Pediatric Intensivist and PICU nurse on regular pediatric floors. A performance assessment checklist and a scoring tool were designed to evaluate team members for responsiveness, effective resuscitation, effective communication and resource utilization.Results:A total of 94 responders participated multiple times in 35 simulations that were conducted in two phases: Codes 1 – 19 as the Pre-PI phase and Codes 20 – 35 as Post-PI phase. Cognitive aids were not utilized during the Pre-PI codes and based on the assessment scores, interventions were introduced in the form of A3 size PALS resuscitation cards, “Pediatric Cardiac Arrest Resuscitation Direction” document with prompts to facilitate smooth running of the code and SBAR notes. Based on the scores, improvement was observed in responsiveness by 27% (Pre-PI:192/262 vs. Post-PI:222/223), effective resuscitation by 38% (Pre-PI:293/511 vs. Post-PI:409/431), effective communication by 46% (Pre-PI:94/245 vs. Post-PI:173/207) and resource utilization by 56% (PrePI:37/94 vs. Post-PI:76/80). Total of 36 (38%) responders participated in actual pediatric cardiac arrests after project completion and 97% (35/36) reported higher confidence.Conclusion:Cognitive aids were helpful supportive tools in overcoming skills and knowledge decay and enhance team performance and quality of resuscitation during code blue simulations. We suggest use of such tools wherever high-fidelity simulation training may not be available.
