Funded by a CDC grant, a trial in Guinea-Bissau randomize newborns to either receive or be denied the hepatitis B birth dose—despite the fact that this vaccine is protective and is recommended by WHO.

"Is this another Tuskegee?"

Scoop: The leaked protocol of the CDC-funded Hepatitis B vaccine trial in Guinea-Bissau. “This is another Tuskegee.”
The protocol reveals that the trial will withhold the Hepatitis B birth dose from thousands—without placebos, without universal maternal screening, and with endpoints critics call indefensible.

Antenatal steroids and CP.

A study of more than 20K preterm births (32–36 wks), used a regression discontinuity design at the 34-week cutoff, found no difference in CP risk just before vs after 34 weeks (RR 0.98; 95% CI 0.50–1.98).

In a meta-analysis including more than 20,000 preterm infants, iNO use was linked to mild reduction in BPD, mortality (only in RCTs), higher ROP (but not the severe disease), and no significant effects on brain injury, IVH, or NEC.

Have you ever wondered why the certainty of evidence is frequently downgraded in neonatal Cochrane reviews?

Here is the answer.

Imprecision and risk of bias were the most common reasons for downgrading the certainty of evidence

pubmed.ncbi.nlm.nih.gov/41379741/
Why is neonatal evidence mainly very low or low certainty - a meta-epidemiological review of Cochrane Neonatal reviews - PubMed
The neonatal evidence was mainly limited due to imprecision and risk of bias. This indicates that larger scale high-quality studies in various neonatal topics are still greatly warranted.

In NICUs, we make critical decisions based on numbers — SpO₂, HR, etc. — assuming our tools are equally accurate. A new study found significant performance gaps between two commonly used pulse-ox systems.

A study of 15,102 infants (23–28 weeks GA) found that each 1-week delay in reaching full enteral feeds (≥120 mL/kg/day) was linked to:
+16% risk of sepsis (ARR 1.16)
Higher NEC risk (ARR 1.20)
More growth faltering in weight, length, and HC.

this study produced a model that can safely reduce ROP screens. Trained on >100k infants and validated on >25k, the model has AUROC 0.916. With 100% sensitivity, NPV was 99.9% and screens dropped 12%. A good tool to improve risk-stratification.

Why it matters:
Vaginal birth may provide cues that jump-start immune & stress pathways.
C-section infants might miss this activation window, possibly contributing to slightly higher rates of asthma/allergies.

Key findings:
- 95 genes were more active in the vaginal-birth group
- IL-6 and IL-8 were also higher
Suggesting vaginal birth “activates” the newborn immune system.
After correction, effects weren’t significant—likely due to small sample size. Think trend, not conclusion

Automated O₂ control improved oxygen stability and reduced key complications in preterm infants; BPD and oxygen dependency.
Larger trials are needed before routine clinical adoption.

Infants managed with CLAC had:
• Shorter ventilation (11 vs. 40 days, p=0.02)
• Less time on O₂ (33 vs. 47 days, p=0.03)
• Lower rates of BPD (55% vs. 84%, p=0.02)
• Fewer required home O₂ (27% vs. 51%, p=0.02)
CLAC reduced hypo- or hypoxemia episodes (p<0.001).
