1. Complications in hospitalized neonates born to mothers with HDP subtypes: a retrospective cohort study and mediation analysis.
In a retrospective cohort with 989 HDP-exposed neonates and 989 controls, both preeclampsia/eclampsia and superimposed preeclampsia increased adverse neonatal outcomes. Mediation analysis showed gestational age as a key mediator: PE/E raised intraventricular hemorrhage via direct and indirect effects, while SP increased neonatal respiratory distress syndrome and intraventricular hemorrhage mainly via gestational age.
Impact: This study advances perinatal epidemiology by quantifying direct versus gestational age-mediated pathways linking HDP subtypes to neonatal complications, including respiratory distress and hemorrhage.
Clinical Implications: Risk stratification and antenatal counseling should consider HDP subtype-specific pathways. Early neonatal monitoring for respiratory distress and hemorrhage is warranted, with strategies to safely prolong gestation where feasible.
Key Findings
- Both PE/E and SP increased risks of preterm birth, small for gestational age, low birth weight, and asphyxia.
- Hematologic complications (neutropenia, polycythemia, thrombocytopenia) were more frequent in HDP-exposed neonates.
- PE/E increased intraventricular hemorrhage via both direct effects and indirect effects through gestational age.
- SP increased neonatal respiratory distress syndrome and intraventricular hemorrhage via indirect effects through gestational age.
Methodological Strengths
- Matched control selection with adjusted logistic regression for neonatal outcomes
- Formal mediation analysis separating direct and gestational age–mediated effects
Limitations
- Retrospective observational design with potential residual confounding
- Generalizability limited to hospitalized neonates
Future Directions: Prospective multicenter studies should test interventions targeting safe gestational prolongation and evaluate HDP subtype-specific neonatal care pathways.
BACKGROUND: Hypertensive disorders in pregnancy (HDP), including four subtypes, are common complications significantly contributing to perinatal morbidity and mortality. Research on the impact of HDP subtypes-preeclampsia/eclampsia (PE/E) and superimposed preeclampsia (SP)-on comprehensive outcomes for hospitalized neonates is relatively limited. Additionally, PE/E and SP often result in shorter gestational age (GA), and the role of GA in the preterm birth-related complications of these HDP subtypes remains unclear. METHODS: This retrospective cohort study identified a total of 989 cases (exposed group), including 845 cases of PE/E and 144 cases of SP . We randomly selected 989 normotensive pregnant women from the same period as controls (control group). Adjusted odds ratios and 95% confidence intervals for neonatal outcomes were calculated using logistic regression. Mediation analysis was conducted to investigate the role of GA in the relationship between HDP subtypes and preterm birth-related complications. RESULTS: Both PE/E and SP increased the risk of adverse birth outcomes, including preterm birth, small for gestational age, low birth weight, and asphyxia, as well as hematological complications such as neutropenia, polycythemia, and thrombocytopenia. PE/E and SP also increased the risk of hypoglycemia while decreasing the risk of pathologic jaundice, with no impact on infection complications. Mediation analysis revealed that PE/E increased the risk of intraventricular hemorrhage while reducing the risk of patent ductus arteriosus and retinopathy of prematurity, both through direct effects (the disease of PE/E itself) and indirect effects (via GA). SP increased the risk of neonatal respiratory distress syndrome and intraventricular hemorrhage through indirect effects (via GA). CONCLUSION: PE/E and SP are key maternal diseases influencing the outcomes of hospitalized neonates, with GA playing an important mediating role in preterm birth-related complications. Early monitoring and management of those mothers and infants are crucial to improving prognosis.
2. Complications in hospitalized neonates born to mothers with HDP subtypes: a retrospective cohort study and mediation analysis.
Focusing on mediation results, gestational age largely explains the elevated risks of neonatal respiratory distress syndrome and intraventricular hemorrhage under superimposed preeclampsia, while preeclampsia/eclampsia exerts both direct and indirect effects on intraventricular hemorrhage and reduces patent ductus arteriosus and retinopathy of prematurity.
Impact: Clarifying direct versus gestational age-mediated pathways refines mechanistic understanding and prioritizes perinatal strategies to mitigate respiratory and neurological complications.
Clinical Implications: Clinical teams should anticipate NRDS and IVH particularly when gestation is shortened by SP; consider antenatal steroids and meticulous neonatal surveillance, while tailoring care by HDP subtype.
Key Findings
- Gestational age mediates the association of SP with increased NRDS and IVH.
- PE/E shows both direct and gestational age-mediated increases in IVH risk.
- PE/E is associated with reduced PDA and ROP via both direct and indirect pathways.
Methodological Strengths
- Causal mediation framework to disentangle direct and indirect effects
- Adjusted logistic regression with reporting of odds ratios and 95% CIs
Limitations
- Observational design limits causal inference despite mediation modeling
- Potential selection bias inherent to hospitalized neonatal populations
Future Directions: Evaluate whether strategies to safely prolong gestation in SP reduce NRDS and IVH and define subtype-specific neonatal care bundles.

3. Mastering esophageal cancer imaging: what radiologists need to know.
This educational review consolidates imaging principles for esophageal cancer across subtypes, emphasizes TNM-based staging, and details recognition of postoperative complications, including ARDS after esophagectomy. It underscores how imaging findings directly shape therapeutic plans and follow-up.
Impact: By integrating staging with postoperative complication imaging, the review provides practical guidance that can reduce morbidity, including prompt recognition of ARDS.
Clinical Implications: Radiologists should apply standardized imaging protocols for staging and vigilantly assess for postoperative complications such as ARDS, anastomotic leak, and pneumonia to inform timely interventions.
Key Findings
- Esophageal SCC and EAC differ in origin, epidemiology, and prognosis, necessitating tailored imaging assessment.
- TNM staging guides prognosis and treatment selection; surgery remains standard for early-stage disease.
- Postoperative complications include ARDS, and imaging is central for detection and management during follow-up.
Methodological Strengths
- Comprehensive synthesis linking imaging features to clinical decision-making
- Clear delineation of postoperative complication imaging patterns
Limitations
- Narrative review without systematic search or quantitative synthesis
- Lack of pooled diagnostic accuracy metrics limits evidence grading
Future Directions: Prospective, multicenter diagnostic accuracy studies and standardized postoperative imaging pathways, potentially leveraging AI, are needed.
Esophageal cancer, particularly squamous cell carcinoma (SCC) and adenocarcinoma (EAC), is a major contributor to cancer-related mortality. The different histopathologic subtypes have different pathological origins, epidemiology and prognosis. TNM staging system allows to stratify the prognosis and determine the most appropriate treatment. Surgery remains the gold standard for treating early-stage esophageal cancer, including various procedures that can adapt to the singular cases helping to reduce morbidity. However, esophagectomy remains burdened by considerable postoperative complications, such as anastomotic leakage, pleural effusion, pneumonia, acute respiratory distress syndrome, stricture formation, chylothorax, delayed gastric emptying, hiatal herniation, and reflux esophagitis. Accurate radiologic evaluation plays a crucial role in detecting, characterizing, and staging esophageal cancer, directly influencing treatment strategies. Radiological imaging is pivotal in determining patient's prognosis, both for the management of post-operative complications and for long-term follow-up. A thorough understanding of the imaging characteristics and underlying pathology is essential for improving diagnostic accuracy and guiding therapeutic decision-making.
