A community-university run conference as a catalyst for addressing health disparities in an urban community.

The African American population of Buffalo, New York experiences striking race-based health disparities due to adverse social determinants of health. A team of community leaders and university faculty determined that a community dialogue was needed to focus research and advocacy on the root causes of these disparities. In response, we organized the annual Igniting Hope conference series that has become the premier conference on health disparities in the region. The series, now supported by an R13 conference grant from NCATS, has been held four times (2018-2021) and has attracted community members, community leaders, university faculty, and trainees. The agenda includes talks by national leaders and breakout/working groups that led to a new state law that has reduced disproportionate traffic-ticketing and drivers' license suspensions in Black neighborhoods; mitigation of the disproportionate COVID-19 fatalities in Black communities; and the launching of a university-supported institute. We describe the key elements of success for a conference series designed by a community-university partnership to catalyze initiatives that are having an impact on social determinants of health in Buffalo.

An influenza A (H3N2) virus outbreak in the Kingdom of Cambodia during the COVID-19 pandemic of 2020.

BACKGROUND: Global influenza virus circulation decreased during the COVID-19 pandemic, possibly due to widespread community mitigation measures. Cambodia eased some COVID-19 mitigation measures in June and July 2020. On 20 August a cluster of respiratory illnesses occurred among residents of a pagoda, including people who tested positive for influenza A but none who were positive for SARS-CoV-2. METHODS: A response team was deployed on 25 August 2020. People with influenza-like illness (ILI) were asked questions regarding demographics, illness, personal prevention measures, and residential arrangements. Respiratory swabs were tested for influenza and SARS-Cov-2 by real-time reverse transcription PCR, and viruses were sequenced. Sentinel surveillance data were analyzed to assess recent trends in influenza circulation in the community. RESULTS: Influenza A (H3N2) viruses were identified during sentinel surveillance in Cambodia in July 2020 prior to the reported pagoda outbreak. Among the 362 pagoda residents, 73 (20.2%) ILI cases were identified and 40 were tested, where 33/40 (82.5%) confirmed positive for influenza A (H3N2). All 40 were negative for SARS-CoV-2. Among the 73 residents with ILI, none were vaccinated against influenza, 47 (64%) clustered in 3/8 sleeping quarters, 20 (27%) reported often wearing a mask, 27 (36%) reported often washing hands, and 11 (15%) reported practicing social distancing. All viruses clustered within clade 3c2.A1 close to strains circulating in Australia in 2020. CONCLUSIONS: Circulation of influenza viruses began in the community following the relaxation of national COVID-19 mitigation measures, and prior to the outbreak in a pagoda with limited social distancing. Continued surveillance and influenza vaccination are required to limit the impact of influenza globally.

Ketorolac tromethamine as compared with morphine sulfate for treatment of postoperative pain.

Ketorolac tromethamine, a nonnarcotic, prostaglandin synthesis-inhibiting analgesic, was compared with morphine sulfate for relief of moderate to severe postoperative pain. The 155 patient participants received single intramuscular doses of either ketorolac, 10, 30, or 90 mg, or morphine, 6 or 12 mg, administered in a double-blind, randomized fashion. Pain scores (verbal and visual analog) were recorded at baseline and assessed at 30 minutes and then hourly to 6 hours. Pain relief was rated at the same times. Ketorolac, 90 and 30 mg, was rated significantly better than morphine, 6 mg, at each assessment interval after 1 hour. Ketorolac, 90 and 30 mg, was rated similarly to morphine, 12 mg, for the first 3 hours and better than morphine, 12 mg, 4 hours after injection. There were no serious side effects reported. The only side effect reported in more than 3% of patients was 8% somnolence with morphine. This study shows ketorolac to be a safe and effective analgesic for relief of postoperative pain.

Mesenchymal stromal cells from the human placenta promote neovascularization in a mouse model in vivo.

Cell transplantation is a promising strategy in regenerative medicine for revascularization of ischemic tissues. Based on our observation that placental mesenchymal stromal cells (PMSC) enhance endothelial cell viability in vitro via secretion of angiogenic factors, we asked whether PMSC support vascular growth in vivo. PMSC were isolated from amnion and placental endothelial cells (PLEC) from chorion and either separately or co-transplanted subcutaneously into immune-deficient mice. Co-transplantation resulted in a higher number of perfused human vessels (CD31+/vimentin+) containing mouse glycophorin A+ erythrocytes. Results indicate positive effects of PMSC on neovascularization in vivo, making them attractive candidates to create autologous PMSC/PLEC pairs for research and transplantation.

Reasons for delay in initiation of antiretroviral therapy in a population of HIV-infected South African children.

The aim of this study was to determine the reasons for delay of antiretroviral therapy (ART) in eligible HIV-infected children after the implementation of the South African National ART programme in April 2004, and to describe implemented interventions to improve ART access. This descriptive, retrospective audit included all HIV-infected children attending an ART clinic from April to December 2004, summarizing the following: (i) demographic data; (ii) HIV disease stage; (iii) CD4+ counts/percentages; (iv) ART eligibility and (v) reasons for ART delay. There were 276 study participants with a mean age of 4 years 4 months (range: 1 month-13 years). According to the South African national guidelines, 243 children were eligible for ART, but only 96 children were initiated on treatment during the study period, which was 39.5% of the eligible group and 34.8% of the total group. Important reasons for treatment delay were: (i) co-infection with tuberculosis (26.4%); (ii) lack of human resources (20.3%); (iii) socio-economic obstacles (17.3%) and (iv) incorrect disease stage classification (13.7%). Paediatric ART clinics need to co-operate closely with existing tuberculosis clinics for the effective management of tuberculosis co-infection; address socio-economic factors of HIV-affected families, especially the legal guardianship in orphans and improve their own staff capacity and the education of medical staff in HIV/AIDS management.
