Background: Despite increasing research on the double burden of malnutrition (DBM; i.e., coexisting over- and undernutrition), there is no global consensus on DBM definitions.
Objectives: To identify published operational DBM definitions, measure their frequency of use, and discuss implications for future assessment.
Methods: Following a structured search of peer-reviewed articles with terms describing "overnutrition" [e.g., overweight/obesity (OW/OB)] and "undernutrition" (e.g., stunting, micronutrient deficiency), we screened 1920 abstracts, reviewed 500 full texts, and extracted 623 operational definitions from 239 eligible articles.
Results: We organized three identified DBM dimensions (level of assessment, target population, and forms of malnutrition) into a framework for building operational DBM definitions. Frequently occurring definitions included coexisting: ) OW/OB and thinness, wasting, or underweight ( = 289 occurrences); ) OW/OB and stunting ( = 161); ) OW/OB and anemia ( = 74); and ) OW/OB and micronutrient deficiency ( = 73).
Conclusions: Existing DBM definitions vary widely. Putting structure to possible definitions may facilitate selection of fit-for-purpose indicators to meet public health priorities.

Worldwide prevalence of the double burden of malnutrition in children and adolescents at the individual level: systematic review and meta-regression.
J Pediatr (Rio J)
December 2024
The University of Texas Health Science Center at Houston, School of Public Health in Austin, Department of Epidemiology, Michael & Susan Dell Center for Healthy Living, Texas Physical Activity Research Collaborative (Texas PARC), Austin, TX, USA. Electronic address:
Objective: This study aimed to assess the prevalence of the double burden of malnutrition (DBM) at the individual level in children and adolescents through a comprehensive literature review.
Sources: Electronic databases, including PubMed, Scopus, and Web of Science, were searched for articles published up until September 9, 2022. Studies reporting individual-level DBM in children and adolescents were included, and meta-regression models were used to investigate potential causes of heterogeneity across studies.
Disparities in steatosis prevalence in the United States by Race or Ethnicity according to the 2023 criteria.

Article Synopsis
- - The 2023 nomenclature for steatotic liver disease (SLD) encompasses metabolic dysfunction-associated SLD (MASLD), alcohol-associated liver disease (ALD), and a mix of both (MetALD), prompting a study on racial and ethnic disparities in SLD prevalence among US adults.
- - Data from the 2017-2018 National Health and Nutrition Examination Survey (NHANES) revealed that 42.4% of participants had MASLD, while the rates for MetALD and ALD were significantly lower (1.7% and 0.6%, respectively), with a higher prevalence observed in Hispanic individuals.
- - Factors such as male gender, age, higher BMI, and various
Countermovement jump and vertical hop demonstrate braking/deceleration and performance alterations after ACL reconstruction with BMA, DBM, and suture tape augmentation.
J Orthop
February 2025
Orthopedic Surgery, Marshall University School of Medicine, 1600 Medical Center Drive, Huntington, WV, 25701, USA.
Objectives: This study evaluated countermovement jump and Single Leg Jump measures to identify landing measures that best distinguish a novel Anterior Cruciate Ligament reconstruction technique using bone marrow aspirate, demineralized bone matrix, and suture tape augmentation patients from controls. The secondary objective assessed performance differences between operated and non-operated limbs post-reconstruction. The hypothesis was that novel Anterior Cruciate Ligament reconstruction patients at return to sport would not differ from controls during landing and that the operated limb's performance would not differ from the unoperated limb.

Renown Health-Pennington Cancer Institute, Reno, Nevada - USA.
Purpose: Circulating tumor cell (CTC)-based (HER2) assay is a laboratory test developed by Epic Sciences using single-cell genomics to detect (HER2) amplification in CTCs found in the peripheral blood of metastatic breast cancer (MBC) patients.
Patients And Methods: Peripheral blood was collected in Streck tubes and centrifugation was used to remove plasma and red blood cells. The remaining nucleated cells were deposited on glass slides, immunofluorescent-stained with proprietary antibodies, scanned by a high-definition digital scanner, and analyzed by a proprietary algorithm.
Central Obesity is an Independent Determinant of Advanced Fibrosis in Lean Patients With Nonalcoholic Fatty Liver Disease.

Department of Hepatology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.
Background: The current definition of lean is based on body mass index (BMI). However, BMI is an imperfect surrogate for adiposity and provides no information on central obesity (CO). Hence, we explored the differences in clinical profile and liver disease severity in lean patients with nonalcoholic fatty liver disease (NAFLD) with and without CO.
