Gastrointestinal Endoscopy in the Neonate

Application of Nanoparticles in the Diagnosis of Gastrointestinal Diseases: A Complete Future Perspective

The diagnosis of gastrointestinal (GI) diseases currently relies primarily on invasive procedures like digestive endoscopy. However, these procedures can cause discomfort, respiratory issues, and bacterial infections in patients, both during and after the examination. In recent years, nanomedicine has emerged as a promising field, providing significant advancements in diagnostic techniques. Nanoprobes, in particular, offer distinct advantages, such as high specificity and sensitivity in detecting GI diseases. Integration of nanoprobes with advanced imaging techniques, such as nuclear magnetic resonance, optical fluorescence imaging, tomography, and optical correlation tomography, has significantly enhanced the detection capabilities for GI tumors and inflammatory bowel disease (IBD). This synergy enables early diagnosis and precise staging of GI disorders. Among the nanoparticles investigated for clinical applications, superparamagnetic iron oxide, quantum dots, single carbon nanotubes, and nanocages have emerged as extensively studied and utilized agents. This review aimed to provide insights into the potential applications of nanoparticles in modern imaging techniques, with a specific focus on their role in facilitating early and specific diagnosis of a range of GI disorders, including IBD and colorectal cancer (CRC). Additionally, we discussed the challenges associated with the implementation of nanotechnology-based GI diagnostics and explored future prospects for translation in this promising field.

Systematic review and meta-analysis of the incidence rates of adverse events after digestive endoscopy in children

BACKGROUND

With the widespread use of digestive endoscopy in children, a variety of adverse events (AEs) have occurred after digestive endoscopy. However, there are notable differences in the incidence of adverse reactions in digestive endoscopy in children at present, which makes it difficult to assess the safety of digestive endoscopy in children.

METHODS

Studies related to digestive endoscopy in children were screened from January 2005 to October 2021 from PubMed, Web of Science, Spring, CNKI, and Science Direct databases. RevMan5.3 and Stata were employed to carry out meta-analysis on the incidence of adverse respiratory events, myoclonus, abdominal pain, fever, bleeding, chest pain, sore throat, vomiting, and delayed capsule discharge after digestive endoscopy in children. The article quality was evaluated by the Agency for Healthcare Research and Quality (AHRQ). The chi-square test and I² were adopted to test literature heterogeneity, and the article publication bias was assessed by displaying an inverted funnel plot as a funnel plot.

RESULTS

In all, 15 articles were included, involving a total of 27,770 children. In all, 15 articles were included, involving a total of 27,770 children. The risk ratio (RR) value of adverse respiratory events after digestive endoscopy in children was 1.31 [95% confidence interval (CI): 1.17 to 1.47, P<0.00001]; the odds ratio (OR) value of the incidence of myoclonus was 1.21 (95% CI: 1.01 to 1.46, P=0.04); the incidence of abdominal pain was 1.18 (95% CI: 1.11 to 1.27, P<0.00001); the incidence of fever was 1.09 (95% CI: 1.06 to 1.12, P<0.00001); the incidence of bleeding was 1.24 (95% CI: 0.94 to 1.64, P=0.13); the incidence of chest pain was 1.06 (95% CI: 1.03 to 1.09, P<0.0001); incidence of sore throat was 1.11 (95% CI: 1.05 to 1.18, P=0.0004); incidence of vomiting was 1.13 (95% CI: 1.06 to 1.21, P=0.0001); and the incidence of delayed capsule expulsion was 1.18 (95% CI: 1.00 to 1.40, P=0.05).

DISCUSSION

The incidence of AEs after digestive endoscopy in children was low, which can be used in the diagnosis and therapy of digestive system diseases in children.

Malabsorption Syndromes and Food Intolerance

Feeding intolerance is ubiquitous in neonatal intensive care units with as many signs and symptoms as possible diagnoses. Optimizing nutrition is paramount in both preterm and term infants. Determining the cause of feeding intolerance and adjusting nutrition interventions is an important part of the daily care of newborns. This review discusses the role of malabsorption and food intolerance as possible causes of nutrition difficulties in the newborn.
