EBUS fine-needle biopsy improved tissue adequacy, not overall diagnostic yield

Journal of bronchology & interventional pulmonology (PubMed)Aug 17, 2026

AI-summarized from the linked source. Educational brief, not medical advice.

Brief summary

A single-center randomized trial of 150 patients found similar overall diagnostic yield with 22-gauge fine-needle biopsy and 19-gauge fine-needle aspiration during EBUS-TBNA, but biopsy produced adequate tissue more often and yielded larger cores.

What NurseJet pulled from the source

Overall diagnostic yield was 94.7% with fine-needle biopsy and 89.3% with aspiration, a difference that was not statistically significant. Adequate tissue was obtained in 98.6% versus 86.7%, and mean core length was 11.52 versus 9.29 mm; a higher histologic diagnostic yield was found only in a post hoc analysis and should be treated as hypothesis-generating.

Why this matters for nurses

Oncology and procedural nurses coordinate preparation, specimen transfer, recovery surveillance, and communication across bronchoscopy and pathology teams. Better tissue adequacy may reduce diagnostic friction, but this study does not show a statistically significant improvement in the primary outcome of overall diagnostic yield.

Bedside takeaway

Fine-needle biopsy yielded more adequate EBUS tissue, but nurses should not describe it as improving overall diagnostic yield in this trial.

How This Applies in Practice

Use this when: Preparing for or recovering a patient from EBUS-TBNA for mediastinal lymphadenopathy when the team is selecting or using a sampling needle.

On your shift

Confirm the selected needle strategy, specimen containers, labeling requirements, and pathology handoff during the procedural pause.
Document samples and transfers according to the bronchoscopy workflow so tissue adequacy is not undermined by a preventable handling error.
Monitor the recovery findings required by protocol, including bleeding, and escalate unexpected changes promptly.

Keep in mind: Needle choice remains a procedural-team decision. The single-center trial did not improve overall diagnostic yield. Follow facility policy, the bronchoscopy protocol, and provider orders.

Key takeaways

The trial randomized 150 consecutive patients to 22-gauge fine-needle biopsy or 19-gauge fine-needle aspiration during EBUS-TBNA.
Overall diagnostic yield did not differ significantly between the two needle strategies.
Fine-needle biopsy produced adequate tissue in 98.6% of procedures versus 86.7% with aspiration and yielded larger tissue cores.
The reported advantage in histologic diagnostic yield came from a post hoc analysis, and minor bleeding was the only reported tolerability issue.

Practice implications

For EBUS-TBNA, confirm the planned needle and specimen workflow during the procedural pause, protect labeling and handoff accuracy, and monitor for bleeding in recovery. Present the tissue-adequacy result separately from the unchanged primary diagnostic-yield result when discussing the evidence with the team.

Limitations & cautions

This was a single-center trial, compared needles of different gauges and designs, and did not show a significant difference in its primary diagnostic-yield outcome. The histologic-yield finding was post hoc, so it cannot establish superiority without confirmation.

Renal failure (PubMed)Sep 7, 2026Research Article

A single-center retrospective cohort found that approximately one quarter of laboratory-defined acute kidney injury cases on internal medicine wards were not documented, particularly when maximal creatinine was lower.

Med-SurgAI summaryReview source

Research ArticleResearchQuality ImprovementAI summary · original source linked below

Among 161 adult hospitalizations meeting serum-creatinine criteria for acute kidney injury, 39 cases (24.2%) were undocumented. Length of stay and in-hospital mortality did not differ significantly by documentation status.

Key takeaways

In the 149 hospitalizations with a demonstrable creatinine change, 33 cases (22.1%) were undocumented.
Higher maximal creatinine was associated with lower adjusted odds of underdocumentation.
The study did not test whether a detection or documentation intervention improves care or outcomes.

Why this matters on shift

A smaller creatinine rise may receive less attention even when it meets the study's laboratory definition of acute kidney injury, which can affect how renal risk is communicated across the inpatient team.

Bedside takeaway

Trend ordered renal-function results and communicate clinically important changes through local escalation and documentation workflows.

Nursing implications

Trend ordered renal-function results and communicate clinically important changes through the care team according to local escalation and documentation workflows.

Limitations & cautions

Abstract-only summary. This was a retrospective, single-center study of 161 hospitalizations; urine-output criteria and reliable preadmission creatinine values were unavailable, and the reference creatinine method may affect case classification.

European heart journal (PubMed)Sep 6, 2026Research Article

In the pragmatic TARGET-D randomized trial, vitamin D dosing titrated to a serum target did not significantly reduce the composite of death, recurrent myocardial infarction, heart-failure hospitalization, or stroke after myocardial infarction.

Telemetry Med-SurgAI summaryReview source

Research ArticleResearchMedication SafetyPatient EducationAI summary · original source linked below

Among 630 participants followed for an average of 4.2 years, major cardiovascular events occurred in 15.7% with targeted vitamin D management and 18.4% with usual care (hazard ratio 0.85, 95% CI 0.58 to 1.24; P=0.40).

Key takeaways

At baseline, 87% of participants had a 25-hydroxyvitamin D level of 40 ng/mL or lower.
The primary composite outcome and the individual outcomes of death, heart-failure hospitalization, and stroke were not significantly different.
A lower recurrent-MI rate was a secondary finding and should not override the nonsignificant primary result.

Why this matters on shift

The trial cautions against presenting targeted vitamin D supplementation as a proven strategy for reducing major cardiovascular events after myocardial infarction.

Bedside takeaway

Present vitamin D as prescribed supplementation, not as a replacement for established post-MI secondary prevention.

Nursing implications

Reinforce the prescribed secondary-prevention plan and avoid implying that vitamin D replaces therapies with established post-MI benefit.

Limitations & cautions

Abstract-only summary. The trial included 630 participants, 78.1% were men, the primary confidence interval included benefit and no benefit, and individual secondary outcomes were not the primary endpoint.

Research ArticleResearchPatient EducationAI summary · original source linked below

Eighty family caregivers at two teaching hospitals in Tehran were randomized. Compared with routine care, the intervention group reported larger reductions in total needs and in health-service, psychological-emotional, work-social, and information domains after four weeks.

Key takeaways

The intervention was designed around family caregivers' supportive-care needs.
All four measured need domains favored the smartphone-education group at four weeks.
The abstract reports statistical significance but does not provide effect sizes or describe the educational content in detail.

Why this matters on shift

Caregiver education is part of oncology care, and mobile delivery may extend structured support beyond brief in-person teaching encounters.

Bedside takeaway

Ask caregivers about unmet information and support needs, then reinforce teaching with approved digital resources.

Nursing implications

Assess what caregivers still need to know and use approved digital education as a supplement to individualized teaching and follow-up.

Limitations & cautions

Abstract-only summary. The trial included 80 caregivers at two hospitals, assessed self-reported needs after only four weeks, and did not report patient outcomes or effect sizes in the abstract.
