(Press-News.org) Reston, VA—The Society of Nuclear Medicine and Molecular Imaging (SNMMI) and 10 other professional societies have issued new appropriate use criteria (AUC) for lymphoscintigraphy in sentinel node mapping and lymphedema/lipedema. The criteria, summarized in the April issue of The Journal of Nuclear Medicine (JNM), include a list of relevant clinical scenarios, a systematic review of evidence in the literature, and a systematic analysis of available evidence, followed by grading each of the clinical scenarios.
Sentinel lymph nodes are the first lymph nodes where cancer cells are most likely to spread from a primary tumor. During a sentinel node biopsy, physicians inject radiotracers into a patient’s body to identify the location of the sentinel node, known as lymphoscintigraphy. Upon identification, the sentinel lymph node is then removed to determine if it is cancerous.
In recent years, advances in radiopharmaceuticals and imaging technology have evolved to expand the clinical use of sentinel node mapping. Given these innovations, an international multidisciplinary panel of expert healthcare providers convened to create AUC to better define recommendations for the use of lymphoscintigraphy among various types of cancers.
The AUC covers four clinical categories of cancer—breast cancer, skin cancer, cancer of other sites, and lymphedema—in a total of 32 clinical scenarios. Pediatric considerations were also addressed. Once these clinical scenarios were identified, the expert panel reviewed and graded them for appropriateness based on available literature as well as expert opinion. Other factors affecting the AUC recommendations were potential harm—including long-term harm that may be difficult to capture—costs, availability, and patient preferences.
“These AUC are intended to assist health care practitioners in considering nuclear lymphoscintigraphy,” noted the authors. “It is hoped that through these recommendations, nuclear medicine lymphatic imaging techniques will be used to benefit patients in the most cost-effective manner.”
SNMMI has developed a multipronged approach to disseminate AUC for lymphoscintigraphy to all relevant stakeholders, including referring physicians, nuclear medicine physicians, and patients. The dissemination and implementation tactics will include a mix of outreach and educational activities targeted to each of these audiences.
The panel included representatives from the SNMMI, Society for Vascular Medicine, Australia and New Zealand Society of Nuclear Medicine, American College of Radiology, Society of Surgical Oncology, European Association of Nuclear Medicine, American Head and Neck Society, American Society of Clinical Oncology, American Society of Breast Surgeons, American College of Nuclear Medicine, and American College of Surgeons. The process for AUC development was modeled after the RAND/UCLA Appropriateness Method for AUC development.
The full AUC for lymphoscintigraphy in sentinel node mapping and lymphedema/lipedema can be viewed on SNMMI's website.

Scientists discover pristine deep-sea coral reefs in the Galápagos Marine Reserve
2023-04-17
17 April 2023 - Galápagos, Ecuador – Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) – the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.
Cresting the ridge of a submerged volcano, and stretching over several kilometers, the impressive reef structure was first recorded by Dr. Michelle ...

Leaps in artificial blood research aim to improve product safety, efficacy
2023-04-17
COLUMBUS, Ohio – Researchers have made huge strides in ensuring that red blood cell substitutes – or artificial blood – are able to work safely and effectively when transfused into the bloodstream.
The key is to make the artificial blood molecules big enough so they don’t leak from blood vessels into tissue and cause dangerous cardiovascular side effects, notes a new study led by researchers from The Ohio State University.
Although blood loss is typically treated by transfusing units of donated blood, in cases where transfusions aren’t readily ...

Researchers discover a new embryonic brain circuit
2023-04-17
EMBARGOED UNTIL 17-APR-2023 11:00 ET
Basel, April 17, 2023 Using a new approach for studying live embryonic mouse brains at single-cell resolution, researchers have identified an active multi-layer circuit that forms in the cortex during an unexpectedly early stage of development. Perturbing the circuit genetically led to changes similar to those seen in the brains of people with autism. The findings are reported today in Cell by a team based at the Institute of Molecular and Clinical Ophthalmology Basel.
“Understanding the detailed development of cell types and circuits in the cortex can provide ...
Study links poor diet to 14 million cases of type 2 diabetes globally
2023-04-17
A research model of dietary intake in 184 countries, developed by researchers at the Friedman School of Nutrition Science and Policy at Tufts University, estimates that poor diet contributed to over 14.1 million cases of type 2 diabetes in 2018, representing over 70% of new diagnoses globally. The analysis, which looked at data from 1990 and 2018, provides valuable insight into which dietary factors are driving type 2 diabetes burden by world region. The study was published April 17 in the journal Nature Medicine.
Of the 11 dietary factors considered, three had an outsized contribution to the rising global incidence of type 2 diabetes: ...
