Background: Low fruit and vegetable (FV) intake in low- and middle-income countries, which is associated with noncommunicable diseases and micronutrient deficiencies, requires food system interventions addressing FV accessibility, affordability, and acceptability. Periodic FV intake monitoring during interventions informs progress toward achieving increased intakes and contributes to understanding the effectiveness of these interventions.

Objectives: This study evaluates the trend in FV intake before, during, and after implementation of a set of nutrition-sensitive food system interventions addressing accessibility, affordability, and acceptability to increase FV consumption over a 1-y period in Vietnamese and Nigerian low-income urban and periurban females.

Recent literature suggests that agricultural value chains are changing rapidly and places an increasing focus on the importance of actors and activities taking place in the "midstream" of these value chains, after production and prior to final sale. This article discusses the financial needs of midstream actors in agricultural value chains, emphasizing differences across midstream activities and highlighting how value chain characteristics can influence both financial needs and potential remedies. The paper concludes with a brief discussion of the prospects of digital financial services and policy levers for government actors in this space.

Myeloid and erythroid precursor vacuolation is a common dysplastic finding associated with myeloid malignancies, toxins, drug, and nutritional deficiencies. It has been described as a core morphologic feature in VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome. We sought to determine the number of cases attributable to VEXAS syndrome in bone marrow biopsies and aspirates (BAMB) reporting myeloid precursor vacuolation.

Obesity interventions for parents of children with obesity can improve children's weight and health. This randomized controlled trial (RCT) evaluated whether a parent-based intervention based on cognitive behavioral therapy (CBT) principles was superior to a parent-based intervention based on a psychoeducation program (PEP) in improving children's obesity. This study was a pragmatic, two-armed, parallel, superiority RCT.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare complication after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) adenoviral vector vaccination. In British Columbia (BC), Canada, a provincial clinical care pathway was developed to guide clinicians in evaluating for VITT among patients who present with thrombocytopenia or thrombosis symptoms within 4 to 28 days after adenoviral vector vaccine exposure. All patients had enzyme-linked immunosorbent assay (ELISA) testing for platelet factor 4 (PF4) antibodies, and all cases with positive PF4-ELISA or d-dimer levels ≥2.

Many patients with solid tumours are treated with targeted pharmacotherapy based on the results of genetic testing ('precision medicine'). This study investigated the use of targeted drugs after OncoFOCUS™+ screening in patients with malignant melanoma, non-small cell lung cancer and metastatic colorectal cancer, and then audited the results against the National Comprehensive Cancer Network (NCCN) guidelines. Patients who were not indicated for targeted pharmacotherapy did not receive such treatment (99%, 100/101).

Background: Pediatric obesity has become increasingly prevalent over recent decades. In view of the psychosocial and physical health risks, and the high likelihood that children with obesity will grow to become adults with obesity, there is a clear need to develop evidence-based interventions that can be delivered in the health care system to optimize the health and well-being of children with obesity and their families. The aim of this paper is to describe the development, implementation, and planned evaluation of a parent-based weight management intervention designed for parents of 8-12 year olds with obesity.

Article Synopsis
  • The study examines a randomized experiment where Salvadoran migrants received matching funds for educational remittances directed to chosen students in El Salvador.
  • Results showed that the matching funds led to higher educational spending, increased attendance in private schools, and reduced youth labor supply in connected households.
  • For every dollar received by the students, educational spending grew by $3.72, with no change in remittances or reductions in support for other students.

Although most theoretical models of household decision making assume perfect information, empirical studies suggest that information asymmetries can have large impacts on resource allocation. I demonstrate the importance of these asymmetries in transnational households, where physical distance between family members can make information barriers especially acute. I implement an experiment among migrants in Washington, DC, and their families in El Salvador that examines how information asymmetries can have strategic and inadvertent impacts on remittance decisions.

Background: Parents play a fundamental role in helping children with obesity to make and maintain healthy lifestyle changes.

Objective: This study aimed to characterize stages of engagement to change nutrition and physical activity habits among parents whose children with obesity were enrolled in obesity management and examine differences in parents' own nutrition and physical activity habits according to their stage of engagement.

Methods: Medical records of 113 children (body mass index [BMI] ≥95th percentile) enrolled in an outpatient weight management clinic were reviewed for baseline (cross-sectional) data.

Background: Over recent decades, the prevalence of pediatric obesity has increased markedly in developed and developing countries, and the impact of obesity on health throughout the lifespan has led to urgent calls for action. Family-based weight management interventions that emphasize healthy lifestyle changes can lead to modest improvements in weight status of children with obesity. However, these interventions are generally short in duration, reported in the context of randomized controlled trials and there are few reports of outcomes of these treatment approaches in the clinical setting.
