Introduction: Acute appendicitis is a common surgical emergency, and the standard approach to diagnosis and management has been codified in several practice guidelines. Adherence to these guidelines provides insight into independent surgical practice patterns and institutional resource constraints as impediments to best practice. We explored data from the recent ESTES SnapAppy observational cohort study to determine guideline compliance in contemporary practice to identify opportunities to close evidence-to-practice gaps.

March 2023

Department of Clinical Epidemiology and Biostatistics, Shanghai Children's Medical Center, Shanghai Jiaotong University School of Medicine, 1678 Dongfang Road, Shanghai, People's Republic of China, 200127.

Consequences of epidemic quarantine on children's well-being are not clear and there are scarce data about the short-term impact of epidemic quarantine on children's growth and development. The study aimed to explore and analyze the potential impacts of the Omicron outbreak on children's growth and development during the lockdown in Shanghai, China. Totally, 4565 children aged 1-36 months who had a routine physical examination in the child health departments of hospitals before (June 1, 2021, to July 6, 2021) and after (June 1, 2022, to July 6, 2022) Shanghai's lockdown were included in this study.

Article Synopsis
  • The study examines how adherence to adjunctive use criteria (AUC) for intravascular ultrasound (IVUS) impacts clinical outcomes in low IVUS volume countries, specifically in Thailand, where over 21,000 patients were analyzed.
  • It found that 75.8% of patients met the AUC, with a higher rate of IVUS-guided PCI performed in that group compared to those who did not meet the criteria.
  • Despite an increase in complications associated with IVUS-guided PCI, the overall procedural success rates improved regardless of AUC adherence, suggesting that IVUS could be beneficial even in cases that do not strictly meet the criteria.

BMC Pediatr

January 2023

Department of Clinical Epidemiology and Biostatistics, Shanghai Children's Medical Center, Shanghai Jiaotong University School of Medicine, 1678 Dongfang Road, Shanghai, 200127, People's Republic of China.

Background: Studies on perinatal risk factors and the developmental delay of children have been inconclusive and few studies have assessed the association between infants and toddlers' body mass index (BMI) and developmental outcomes.

Methods: We conducted a cross-sectional study of children aged 1-36 months who had a routine physical examination in the child health departments of hospitals from March 2018 to November 2021 in 16 provinces, 4 autonomous regions and 2 municipalities directly under the central government by using the Infant Toddler Growth Development Screening Test (ITGDST). Normal children were defined as those with scores ≥ mean - 2 standard deviations (SD), while children with developmental delay were those with scores < mean-2SD in terms of overall development, gross motor, fine motor and language development.
