Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infections and Reinfections Among Fully Vaccinated and Unvaccinated University Athletes-15 States, January-November 2021.

BACKGROUND: Limited data currently exist on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections among fully vaccinated persons or reinfections in college-aged populations. Centers for Disease Control and Prevention (CDC) partnered with National Collegiate Athletic Association (NCAA) institutions to analyze retrospective data and present characteristics of positive coronavirus disease 2019 (COVID-19) cases among student athletes 18 years of age and older. METHODS: De-identified, individual-level data contributed by 21 universities on 1378 student athletes who tested positive for SARS-CoV-2 from January through November 2021 (pre-Omicron) were examined to determine percentages of infection among unvaccinated, partially vaccinated, and fully vaccinated individuals (breakthrough infections) as well as reinfections. Comparisons by demographic characteristics and regions were also made to further characterize these infections. RESULTS: Among the 1378 student athletes positive for SARS-CoV-2, 1070 (77.6%) were infected when unvaccinated and 22.4% (n = 308) were infected after full vaccination. There was a significant difference between Black (14.7%, n = 40) and White (23.9%, n = 168) student athletes who experienced a SARS-CoV-2 infection after being fully vaccinated (P < .01). Proportions of infections among fully vaccinated individuals did not differ statistically by sex (p = 0.06). CONCLUSIONS: This article adds to the knowledge of SARS-CoV-2 infections among fully vaccinated individuals in college-aged populations. The level of infections among fully vaccinated student athletes indicates the need for maintaining precautions to prevent infection. Further study of COVID-19 vaccination, infection, and reinfection among the well-resourced and diverse population of student athletes might contribute further understanding of factors that play a role in health equity among young adults.

Health and Health Care Use of American Indian/Alaska Native Women Veterans: A Scoping Review.

BACKGROUND: American Indian/Alaska Native (AI/AN) women serve in the U.S. military, use Veterans Health Administration (VA) health care, and reside in rural areas at the highest rates compared with other women veterans. However, little is known about their unique health care needs, access, and health care use. OBJECTIVE: We assessed the existing literature on the health and health care use of U.S. AI/AN women veterans. METHODS: Online databases were searched to identify studies. Study characteristics extracted included health care topic, study design, overall sample size and number of AI/AN women veterans, and funding source. We screened 1,508 publications for inclusion; 28 publications were ultimately retained. RESULTS: Health care access and use were the most common health care research topics (39%), followed by mental health (36%) and physical health (25%). Few studies considered the impact of rurality. Most studies found significant differences between AI/AN women veterans and other women veterans or AI/AN men veterans. Publication dates ranged from 1998 to 2023, with 71% published after 2010. The majority of studies (75%) were secondary analyses of extant health care data. More than three-quarters of studies (82%) were funded federally (e.g., VA). Many studies were based on VA administrative data, resulting in a gap in knowledge regarding AI/AN women veterans who are not eligible for, or choose not to use, VA health care. CONCLUSION: Research to inform the health and health care of AI/AN women veterans is limited, especially in terms of known AI/AN and women veterans' prevalent health concerns (e.g., diabetes, hypertension), women's health and reproduction, and how AI/AN women veterans access, use, and confront barriers to health care. Moreover, there is scarce research specific to cultural, tribal, and regional factors that likely affect access and use of particular health care systems or that can affect perspectives on illness that impact long-term treatment adherence and patient outcomes.

Blood Pressure, Readmission, and Mortality Among Patients Hospitalized With Acute Kidney Injury.

Importance: Acute kidney injury (AKI) complicates 20% to 25% of hospital admissions and is associated with long-term mortality, especially from cardiovascular disease. Lower systolic blood pressure (SBP) following AKI may be associated with lower mortality, but potentially at the cost of higher short-term complications. Objective: To determine associations of SBP with mortality and hospital readmissions following AKI, and to determine whether time from discharge affects these associations. Design, Setting, and Participants: This retrospective cohort study of adults with AKI during a hospitalization in Veteran Healthcare Association (VHA) hospitals was conducted between January 2013 and December 2018. Patients with 1 year or less of data within the VA system prior to admission, severe or end-stage liver disease, stage 4 or 5 chronic kidney disease, end-stage kidney disease, metastatic cancer, and no blood pressure values within 30 days of discharge were excluded. Data analysis was conducted from May 2022 to February 2024. Exposure: SBP was treated as time-dependent (categorized as <120 mm Hg, 120-129 mm Hg, 130-139 mm Hg, 140-149 mm Hg, 150-159 mm Hg, and ≥160 mm Hg [comparator]). Time spent in each SBP category was accumulated over time and represented in 30-day increments. Main Outcomes and Measures: Primary outcomes were time to mortality and time to all-cause hospital readmission. Cox proportional hazards regression was adjusted for demographics, comorbidities, and laboratory values. To evaluate associations over time, hazard ratios (HRs) were calculated at 60 days, 90 days, 120 days, 180 days, 270 days, and 365 days from discharge. Results: Of 237 409 admissions with AKI, 80 960 (57 242 aged 65 years or older [70.7%]; 77 965 male [96.3%] and 2995 female [3.7%]) were included. The cohort had high rates of diabetes (16 060 patients [20.0%]), congestive heart failure (22 516 patients [28.1%]), and chronic lung disease (27 682 patients [34.2%]), and 1-year mortality was 15.9% (12 876 patients). Overall, patients with SBP between 130 and 139 mm Hg had the most favorable risk level for mortality and readmission. There were clear, time-dependent mediations on associations in all groups. Compared with patients with SBP of 160 mm Hg or greater, the risk of mortality for patients with SBP between 130 and 139 mm Hg decreased between 60 days (adjusted HR, 1.20; 99% CI, 1.00-1.44) and 365 days (adjusted HR, 0.58; 99% CI, 0.45-0.76). SBP less than 120 mm Hg was associated with increased risk of mortality at all time points. Conclusions and Relevance: In this retrospective cohort study of post-AKI patients, there were important time-dependent mediations of the association of blood pressure with mortality and readmission. These findings may inform timing of post-AKI blood pressure treatment.

Historically black college and university (HBCU) COVID-19 return-to-campus policies and prevention measures-Fall 2021.

Objectives: Examine publicly accessible HBCU COVID-19 policies and associations with community COVID-19 infection and vaccination rates, and utilization of a dashboard. Participants: Excluding unaccredited or closed programs (n = 5) and those without COVID-19 information on website (n= 18), 76 HBCUs were included. Methods: Data on vaccine requirements, masking, and other policies were collected. Student enrollment and demographics and community infection and vaccination rates were obtained from websites. Results: Between August 15 and September 6, 2021, 36% of HBCU websites indicated vaccination requirements for students, with differences by private (57%) and public (17%). Masking requirements were more prevalent in HBCUs in areas with >50% community vaccination coverage vs those with <25%. Private institutions were more likely than public to require faculty/staff testing (34% vs 19%). HBCUs in areas with low/moderate COVID-19 rates were twice as likely to require vaccinations than HBCUs with higher rates. Conclusions: Easily accessible COVID-19 policies may help guide community prevention measures.
