Captopril to Lisinopril Conversion in Pediatric Cardiothoracic Surgery Patients Less Than 7 Years of Age (RISE-7).

Hypertension after cardiothoracic surgery is common, often requiring pharmacologic management. The recommended first-line antihypertensives in pediatrics are angiotensin converting enzyme inhibitors. Captopril and enalapril are approved for infants and children; however, lisinopril is only approved for > 7 years of age. This study evaluated safety and efficacy of converting from captopril to lisinopril in patients utilizing a pre-defined conversion of 3 mg captopril to 1 mg lisinopril. This was a single center, retrospective study including patients less than 7 years of age admitted for cardiothoracic surgery who received both captopril and lisinopril from 01/01/2017 to 06/01/2022.The primary outcome was mean change in systolic blood pressure (SBP) from baseline for 72 h after conversion of captopril to lisinopril. A total of 99 patients were enrolled. There was a significant decrease in mean SBP (99.12 mmHg vs 94.86 mmHg; p = 0.007) with no difference in DBP (59.23 mmHg vs 61.95 mmHg; p = 0.07) after conversion to lisinopril. Of the 99 patients who were transitioned to lisinopril, 79 (80%) had controlled SBP, 20 (20%) remained hypertensive, 13 (13%) received an increase in their lisinopril dose, and 2 (2%) required an additional antihypertensive agent. There was a low overall rate of AKI (3%) and hyperkalemia (4%) respectively. This study demonstrates that utilizing lisinopril with a conversion rate of 3 mg of captopril to 1 mg of lisinopril was safe and effective for controlling hypertension in pediatric patients following cardiothoracic surgery.

Childcare and School Acute Gastroenteritis Outbreaks: 2009-2020.

OBJECTIVES: Acute gastroenteritis (AGE) outbreaks commonly occur in congregate settings, including schools and childcare facilities. These outbreaks disrupt institutions, causing absences and temporary facility closures. This study analyzed the epidemiology of school and childcare AGE outbreaks in the United States. METHODS: We analyzed AGE outbreaks occurring in kindergarten to grade 12 schools and childcare facilities reported via the National Outbreak Reporting System in the United States from 2009 to 2019 and compared this information to 2020 data. Outbreak and case characteristics were compared using the Kruskal-Wallis rank sum test, χ2 goodness-of-fit test, and Fisher exact test. RESULTS: From 2009 to 2019, there were 2623 school, 1972 childcare, and 38 school and childcare outbreaks. School outbreaks were larger (median, 29 cases) than childcare outbreaks (median, 10 cases). Childcare outbreaks were longer (median, 15 days) than school outbreaks (median, 9 days). Norovirus (2383 outbreaks; 110 190 illnesses) and Shigella spp. (756 outbreaks; 9123 illnesses) were the most reported etiologies. Norovirus was the leading etiology in schools; norovirus and Shigella spp. were dominant etiologies in childcare centers. Most (85.7%) outbreaks were spread via person-to-person contact. In 2020, 123 outbreaks were reported, 85% in the first quarter. CONCLUSIONS: Schools and childcare centers are common AGE outbreak settings in the United States. Most outbreaks were caused by norovirus and Shigella spp. and spread via person-to-person transmission. Fewer outbreaks were reported in 2020 from the COVID-19 pandemic. Prevention and control efforts should focus on interrupting transmission, including environmental disinfection, proper handwashing, safe diapering, and exclusion of ill persons.

Outbreaks of Acute Gastrointestinal Illness Associated with a Splash Pad in a Wildlife Park - Kansas, June 2021.

In June 2021, Kansas state and county public health officials identified and investigated three cases of shigellosis (a bacterial diarrheal illness caused by Shigella spp.) associated with visiting a wildlife park. The park has animal exhibits and a splash pad. Two affected persons visited animal exhibits, and all three entered the splash pad. Nonhuman primates are the only known animal reservoir of Shigella. The splash pad, which sprays water on users and is designed so that water does not collect in the user area, was closed on June 19. The state and county public health codes do not include regulations for splash pads. Thus, these venues are not typically inspected, and environmental health expertise is limited. A case-control study identified two distinct outbreaks associated with the park (a shigellosis outbreak involving 21 cases and a subsequent norovirus infection outbreak involving six cases). Shigella and norovirus can be transmitted by contaminated water; in both outbreaks, illness was associated with getting splash pad water in the mouth (multiply imputed adjusted odds ratio [aORMI] = 6.4, p = 0.036; and 28.6, p = 0.006, respectively). Maintaining adequate water disinfection and environmental health expertise and targeting prevention efforts to caregivers of splash pad users help prevent splash pad-associated outbreaks. Outbreak incidence might be further reduced when U.S. jurisdicitons voluntarily adopt CDC's Model Aquatic Health Code (MAHC) recommendations and through the prevention messages: "Don't get in the water if sick with diarrhea," "Don't stand or sit above the jets," and "Don't swallow the water."†.

Evolving Epidemiology of Reported Giardiasis Cases in the United States, 1995-2016.

BACKGROUND: Giardiasis is the most common intestinal parasitic disease of humans identified in the United States (US) and an important waterborne disease. In the United States, giardiasis has been variably reportable since 1992 and was made a nationally notifiable disease in 2002. Our objective was to describe the epidemiology of US giardiasis cases from 1995 through 2016 using National Notifiable Diseases Surveillance System data. METHODS: Negative binomial regression models were used to compare incidence rates by age group (0-4, 5-9, 10-19, 20-29, 30-39, 40-49, 50-64, and ≥ 65 years) during 3 time periods (1995-2001, 2002-2010, and 2011-2016). RESULTS: During 1995-2016, the average number of reported cases was 19 781 per year (range, 14 623-27 778 cases). The annual incidence of reported giardiasis in the United States decreased across all age groups. This decrease differs by age group and sex and may reflect either changes in surveillance methods (eg, changes to case definitions or reporting practices) or changes in exposure. Incidence rates in males and older age groups did not decrease to the same extent as rates in females and children. CONCLUSIONS: Trends suggest that differences in exposures by sex and age group are important to the epidemiology of giardiasis. Further investigation into the risk factors of populations with higher rates of giardiasis will support prevention and control efforts.
