Semaglutide reduced weight in adults without diabetes across nine trials

International journal of obesity (2005) (PubMed)Aug 29, 2026

Brief summary

A meta-analysis of placebo-controlled trials found subcutaneous semaglutide reduced body weight, waist circumference, and C-reactive protein in adults with overweight or obesity without diabetes.

What NurseJet pulled from the source

Nine randomized trials included 6,239 participants. Compared with placebo, semaglutide reduced body weight by a mean 12.04 percentage points and waist circumference by 9.36 cm; serious adverse-event risk did not differ significantly (RR 1.12, 95% CI 0.76-1.65). Longer-term efficacy and safety remain uncertain.

Why this matters for nurses

Nurses increasingly encounter semaglutide in weight-management care. The findings help frame expected population-level benefit while preserving medication reconciliation, adverse-effect assessment, dose-specific teaching, and realistic discussion of longer-term uncertainty.

Bedside takeaway

Pair weight-response monitoring with dose-specific medication reconciliation, tolerance assessment, and realistic long-term uncertainty.

How This Applies in Practice

Use this when: Caring for an adult prescribed subcutaneous semaglutide for weight management without diabetes.

On your shift

Reconcile the exact product, current dose, titration schedule, indication, last administration, and other medications.
Assess tolerance, hydration and nutrition, weight trend, administration technique, and barriers to follow-up.
Escalate concerning symptoms, dosing errors, or inability to maintain intake through the prescribing team's approved pathway.

Keep in mind: Do not infer an individual response from pooled averages or change dosing independently. Follow facility policy and provider orders.

Key takeaways

The review included nine randomized placebo-controlled trials and 6,239 adults without diabetes.
Mean percentage body-weight change favored semaglutide by 12.04 percentage points.
Waist circumference and C-reactive protein also decreased relative to placebo.
Serious adverse events did not differ significantly, but the review called for longer-term safety and efficacy data.

Practice implications

Confirm the product, prescribed dose and titration, indication, administration technique, missed-dose plan, tolerance, and follow-up. Report concerning symptoms or inability to maintain hydration and nutrition through the prescribing team's established pathway.

Limitations & cautions

The abstract reports nine placebo-controlled trials but does not establish long-term outcomes across all clinical populations. The serious-adverse-event estimate was imprecise, and pooled efficacy should not be used to predict an individual's response or support an unprescribed dose change.

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.

Journal of neurology (PubMed)Sep 6, 2026Systematic Review

A cumulative meta-analysis found longer survival over time in Duchenne muscular dystrophy, alongside a shift from predominantly respiratory toward cardiac causes of death.

Peds ICUAI summaryReview source

Systematic ReviewResearchPatient EducationAI summary · original source linked below

The review included 53 studies and more than 13,000 patients. Pooled median survival was 29 years among ventilated patients and 19 years among non-ventilated patients, but these study-level observational comparisons do not establish that ventilation alone caused the difference.

Key takeaways

Sixty percent of patients in the included studies received home mechanical ventilation.
Survival improved progressively over time in both ventilated and non-ventilated groups.
As respiratory survival improved, cardiac and other causes accounted for a larger share of deaths.

Why this matters on shift

Patients living longer with Duchenne muscular dystrophy may need sustained respiratory support plus ongoing cardiac and multisystem surveillance across care transitions.

Bedside takeaway

Verify each patient's established respiratory and cardiac plan during admissions and care transitions.

Nursing implications

During admissions and handoffs, verify the established ventilation, airway-clearance, and cardiac-monitoring plan and coordinate concerns with the multidisciplinary team.

Limitations & cautions

Abstract-only summary. This was a study-level meta-analysis of heterogeneous observational survival reports; the ventilated and non-ventilated groups were not randomized, so associations should not be interpreted as treatment effects.
