Summary
Three impactful endocrinology studies stood out: an intraoperative dual near-infrared imaging strategy halved 1-year hypoparathyroidism after total/completion thyroidectomy; patient-derived medullary thyroid cancer organoids were established with preserved function, enabling future TKI and PET tracer testing; and a meta-analysis of randomized trials showed whole fruit-based products modestly improve HbA1c in type 2 diabetes. Collectively, these works advance surgical safety, precision oncology modeling, and pragmatic nutrition therapy.
Research Themes
- Intraoperative imaging to prevent post-thyroidectomy hypoparathyroidism
- Patient-derived organoids for precision endocrinology-oncology
- Dietary whole fruit interventions for glycemic control in T2D
Selected Articles
1. Combined near-infrared autofluorescence and preresection indocyanine green angiography for parathyroid gland preservation during thyroid surgery: A clinical controlled trial.
In a matched controlled study (154 intervention, 462 controls), combining intraoperative parathyroid near-infrared autofluorescence with preresection ICG angiography significantly reduced 1-year hypoparathyroidism after total/completion thyroidectomy. Adjusted analyses showed an 84% relative risk reduction.
Impact: Demonstrates a pragmatic intraoperative imaging protocol that halves long-term hypoparathyroidism—a major morbidity of thyroidectomy—potentially shifting standard surgical workflow.
Clinical Implications: Adopting dual NIR autofluorescence and preresection ICG angiography can improve parathyroid identification and perfusion preservation, reducing long-term calcium/vitamin D dependence and readmissions. Training and equipment integration into endocrine surgery programs should be considered.
Key Findings
- 1-year hypoparathyroidism occurred in 6.5% with dual NIR imaging vs 12.3% with standard care.
- Unadjusted odds ratio 0.50 (95% CI 0.248–0.996); adjusted odds ratio 0.16 (95% CI 0.048–0.560).
- Matched, controlled comparison across 154 intervention and 462 control patients undergoing total/completion thyroidectomy.
Methodological Strengths
- Matched controlled design with 1:3 matching and multivariable adjustment for key surgical and patient factors.
- Clinically meaningful, long-term endpoint (1-year hypoparathyroidism) in a sizable cohort.
Limitations
- Nonrandomized, single-institution design with retrospective controls may introduce residual confounding.
- Generalizability may be limited by device availability, learning curve, and institutional expertise.
Future Directions: Prospective multicenter randomized trials to validate efficacy, cost-effectiveness analyses, and standardized training curricula for widespread adoption.
2. A meta-analysis of available data of the effects of selected whole and powdered fruits on glycemia in type 2 diabetes.
This meta-analysis of five RCTs (n=245) found that whole fruit-based products produce modest but significant improvements in glycemic control in T2D, lowering HbA1c by 0.33%, reducing fasting glucose, and increasing HDL. Heterogeneity was low-to-moderate and no serious adverse events were reported.
Impact: Provides evidence-based support for recommending whole fruit as part of T2D dietary management, countering concerns about fruit sugars and informing guidelines.
Clinical Implications: Clinicians can encourage incorporation of whole fruit or selected fruit-based products into T2D diets to achieve modest HbA1c reductions and lipid benefits, while monitoring individual glycemic responses and portion sizes.
Key Findings
- HbA1c decreased by −0.33% (95% CI −0.54% to −0.11%) with whole fruit-based products.
- Fasting blood glucose decreased by −6.59 mg/dL; HDL increased by 2.72 mg/dL.
- Heterogeneity was low to moderate (I²=44% for HbA1c; 0% for FBG and HDL); no serious adverse events reported.
Methodological Strengths
- Randomized controlled trials only; pre-registered meta-analysis (PROSPERO).
- Consistent directionality across outcomes with low heterogeneity for key secondary endpoints.
Limitations
- Only five trials with relatively small total sample; variable fruit types and formulations (whole vs powdered).
- Short-to-moderate intervention durations limit assessment of long-term sustainability and complications.
Future Directions: Larger, longer RCTs comparing specific fruits, doses, and delivery forms (whole vs processed) with standardized co-interventions, and evaluation of CGM-derived glycemic variability.
3. Patient-derived medullary thyroid cancer organoids: a potential model for mechanistic studies on diagnostics and therapy.
The authors successfully established patient-derived MTC organoids from 10 biopsies that preserved calcitonin/CEA production and MTC-specific gene/protein profiles, with self-renewal across passages. Proof-of-principle exposure to TKIs and PET tracers suggests feasibility for individualized diagnostic and therapeutic testing.
Impact: Introduces a first-of-its-kind MTC organoid platform enabling functional testing where clinical trials are constrained by rarity, laying groundwork for precision selection of TKIs and imaging tracers.
Clinical Implications: While not yet ready for routine use, patient-derived MTC organoids could inform personalized TKI choice and PET tracer selection, potentially reducing ineffective therapy and optimizing surveillance imaging.
Key Findings
- Established organoids from 10 MTC biopsies with sustained self-renewal across passages.
- Organoids preserved MTC functionality, producing calcitonin and CEA; MTC-specific markers confirmed by qPCR and immunofluorescence.
- Proof-of-principle TKI and PET tracer exposures demonstrated feasibility for future personalized testing.
Methodological Strengths
- Use of patient-derived tissue with validation of gene/protein expression and functional hormone secretion.
- Assessment of self-renewal and preliminary pharmacologic/imaging tracer feasibility.
Limitations
- Small sample size (n=10) limits generalizability and statistical inference.
- TKI and PET tracer experiments were preliminary without correlation to clinical outcomes.
Future Directions: Develop multicenter MTC organoid biobanks, standardize assays linking in vitro responses to clinical outcomes, and explore co-culture and microenvironment modeling.
