Abstract
BACKGROUND Canadian immunization programs for rotavirus started in 2011. We sought to determine their effect on the burden of community-acquired admissions and hospital-acquired rotavirus at pediatric hospitals. METHODS The Canadian Immunization Monitoring Program Active (IMPACT) network conducted active surveillance for rotavirus-positive hospital admissions between 2005 and 2020 at 12 pediatric hospitals. We used yearly rates of community-acquired rotavirus per 10 000 admissions and hospital-acquired rotavirus infections per 1000 patient-days to determine changes in the pre- and post-vaccine program periods. RESULTS During the 15-year study period, 5691 rotavirus hospital admissions and hospital-acquired infections were detected, including 4323 (76%) community-acquired infections and 1368 (24%) hospital-acquired infections. The average community-acquired rate in the pre-vaccine period was 60.3 (95% confidence interval [CI] 53.7-68.3) per 10 000 admissions, with a decline to 11.0 (95% CI 7.5-15.1) per 10 000 admissions in the post-vaccine period, resulting in an average reduction of 81.7% (95% CI 74.4%-87.8%). The rate of hospital-acquired rotavirus declined from 0.35 (95% CI 0.29-0.41) per 1000 patient-days in the pre-vaccine period to 0.05 (95% CI 0.03-0.07) per 1000 patient-days in the post-vaccine period, resulting in an 85.3% (95% CI 77.7%-91.9%) average decline. Herd protection was present among children aged 2-16 years. INTERPRETATION Although start dates of rotavirus vaccine programs across provinces varied, there was around an 80% average decrease in both community-acquired and hospital-acquired rotavirus infections at pediatric hospitals in Canada in the 1- to 9-year interval after implementation of rotavirus vaccine programs. Herd protection is an important aspect of rotavirus vaccines for other children who are not vaccine eligible, and rotavirus vaccines continue to provide important benefits both for children and health care systems.

Abstract
BACKGROUND Monitoring the risk of intussusception after the introduction of rotavirus vaccines is recommended by the World Health Organization (WHO). Although the validity of intussusception monitoring using electronic health records (EHRs) has been confirmed previously, no similar studies have been conducted in China. We aimed to verify the diagnosis and determine an algorithm with the best performance for identification of intussusception using Chinese EHR databases. RESEARCH DESIGN AND METHODS Using the Regional Health Information Platform in Ningbo, patients aged 0-72 months from 2015 to 2021 with any related visits for intussusception were included. The algorithms were based on diagnostic codes or keywords in different clinical scenarios, and their performance was evaluated with positive predictive value (PPV) and sensitivity in line with the Brighton guidelines. RESULTS Brighton level 1 intussusception was confirmed in 2958 patients with 3246 episodes. Fine-tuned algorithms combining the appearance of the relevant ICD-10 codes or the Chinese keyword 'Chang Tao' in any diagnostic reports with the results of enema treatments or related surgeries showed the highest sensitivity, while the highest PPV was obtained by further criteria based on typical radiographic appearances. CONCLUSION Intussusception could be identified and validated internally using EHRs in Ningbo.

Abstract
BACKGROUND Worldwide rotavirus vaccination has resulted in a substantial decrease in rotavirus-induced severe gastroenteritis and related hospitalizations among children. Still, the characterization of patients warranting hospitalization needs to be further elucidated. The purpose of the study is to compare the clinical and laboratory features of children hospitalized with acute rotavirus infection before and after the introduction of routine vaccination. METHODS This is a retrospective observational study. Participants were pediatric patients who presented to the Bnai Zion Medical Center pediatric emergency department and were diagnosed with rotavirus acute gastroenteritis between 2017 and 2019. RESULTS During the pre-vaccination period (2007-2009), 114 infants and young children (median age: 14 months, range: 1-72 months; 59 male, 55 female) were hospitalized for rotavirus-induced acute gastroenteritis with a rate of 11.71 positive rotavirus tests per 1000 emergency room visits. In the post-vaccination period (2012-2019), 168 infants and young children (median age: 17 months, range: 0-84 months; 90 male, 78 female) were hospitalized with a rate of 4.18 positive rotavirus tests per 1000 emergency room visits. There were no statistical differences between the two groups in gender, breast-feeding rates and sibling(s). The proportion of cases with moderate-to-severe dehydration was higher in the post-vaccination children than in the pre-vaccination children. CONCLUSIONS Rates of rotavirus-attributed acute gastroenteritis hospitalizations declined from the pre- to the post-vaccination period. Higher rates of dehydration were found in the post-vaccination children. Ongoing surveillance is warranted to better understand the implications of the vaccine.

Evidence of a plateau in the incidence of type 1 diabetes in children 0-4 years of age from a regional pediatric diabetes center; Auckland, New Zealand: 1977-2019. Pediatr Diabetes 2021; 22:854-860. [PMID: 34018288 DOI: 10.1111/pedi.13236] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 03/28/2021] [Accepted: 04/29/2021] [Indexed: 12/16/2022] Open
Abstract
OBJECTIVE To determine the incidence of new onset type 1 diabetes in children aged 0-14 years from 1977 to 2019 in Auckland, New Zealand. RESEARCH DESIGN AND METHODS A cohort study of children with type 1 diabetes aged 0-14 years (n = 1688; 50.4% male) managed by the regional diabetes service between 1977 and 2019. Incidence rates were estimated using census data. RESULTS The incidence of type 1 diabetes increased by 2.9%/year from 1977 to 2006 (95% confidence interval [CI] 2.13% - 3.48%). Although there was no significant change from 2006 to 2019 (-0.3%/year, 95% CI -1.62% - 1.08%), there was a dramatic fall from 1976 to 2018 in the proportion of New Zealand Europeans, from 69.9 to 33.9%. New Zealand Europeans had the highest incidence (23.3/100,000, 95% CI 20.6-26.1) compared to Māori (8.3/100,000, 95% CI 6.3-10.2), Pasifika (8.6/100,000, 95% CI 6.9-10.4) and other (6.4/100,000, 95% CI 4.7-8.0). All groups showed an overall increase in incidence over time, Māori 4.4%/year, Pasifika 3.7%, compared to New Zealand European 2.7%, and other 2.1%. Incidence increased consistently in 5-9 and 10-14 year olds (2.0% and 2.2%/year, respectively). By contrast, whereas 0-4 year olds showed an increase of 4.6%/year from 1977 to 2003 (p < 0.01), there was no change from 2003 to 2019 (p = 0.2). CONCLUSION There has been a plateau in the incidence of type 1 diabetes in children 0-4 years of age in the Auckland region since 2003, but not older children. The apparent plateau in the overall incidence of new onset type 1 diabetes in children 0-14 years since 2006 was mediated by substantial changes in the ethnic makeup of the Auckland region.
