Children with mild hyponatremia at the emergency department are at higher risk of hospitalization

Updates in hyponatremia and hypernatremia

PURPOSE OF REVIEW

Hyponatremia and hypernatremia are commonly encountered electrolyte abnormalities that require timely and careful intervention, as they can be associated with significant morbidity and mortality.

RECENT FINDINGS

This review article addresses the etiology, presentation, diagnosis, and management of both hyponatremia and hypernatremia, emphasizing the latest advancements and emerging trends in pediatric care.

SUMMARY

A methodical approach is needed to accurately assess and treat hyponatremia and hypernatremia. Both conditions continue to rely on serum and urine testing, however newer tests such as copeptin and stimulated testing may hold promise to further refine testing in the future.

A Nomogram for Predicting Surgical Risk in Neonates with Necrotizing Enterocolitis: A Retrospective Cohort Study

OBJECTIVES

To construct a nomogram that predicts the risk of surgery in patients with necrotizing enterocolitis (NEC).

METHODS

This retrospective cohort study recruited patients diagnosed with NEC at the Children's Hospital of Soochow University from 2013 to 2023. The neonates were divided into conservative and surgical-treatment groups. Univariate and multivariate logistic regressions were performed to identify factors influencing surgical risk, and a predictive model was constructed.

RESULTS

This study comprised 154 cases of NEC, 103 cases (66.9%) in the conservative group and 51 cases (33.1%) in the surgical group. Multivariate logistic regression analysis revealed that increased bloody stools [odds ratio (OR) 5.066; 95% confidence interval (CI) 1.7396-14.7532; p = 0.0029), oxygen inhalation (OR 1.8278; 95% CI 1.2113-2.7581; p = 0.0041), use of vasoconstrictors (OR 4.4446; 95% CI 1.7157-11.5137; p = 0.0021), portal venous gas (OR 4.5569; 95% CI 1.6324-12.7209; p = 0.0038), and blood sodium (OR 0.8339; 95% CI 0.7477-0.9301; p = 0.0011) were independent factors of surgical risk. The area under the nomogram's receiver operating characteristic (ROC) curve was 0.886. Decision curve analysis (DCA) and calibration curves demonstrated good predictive performance for the nomogram.

CONCLUSIONS

The nomogram effectively assessed the risk of surgical intervention in NEC patients, providing new insights and references for diagnosing and treating NEC.
