Food access

Binge eating disorder, characterized by the overconsumption of food in a discrete time period, is the most common eating disorder in the United States, but its neurological basis is not fully understood. The paraventricular nucleus of the thalamus (PVT) is a limbic brain region implicated in eating, and the anorexigenic neuropeptide, pituitary adenylate cyclase-activating polypeptide (PACAP), is densely expressed in the PVT. This study sought to examine the possible involvement of PACAP in the PVT in binge-type eating...

Central fatigue is a common pathological state characterized by psychological loss of drive, lack of appetite, drowsiness, and decreased psychic alertness. The mechanism underlying central fatigue is still unclear, and there is no widely accepted successful animal model that fully represents human characteristics. We aimed to construct a more clinically relevant and comprehensive animal model of central fatigue. In this study, we utilized the Modified Multiple Platform Method (MMPM) combined with alternate-day fasting (ADF) to create the animal model...

The "Food as Medicine" (FAM) movement encourages public health and medical professionals to recognize the importance of dietary patterns and food access. The purpose of this work was to describe patient and physician engagement with a produce prescription (PRx) program to improve access to fresh vegetables in a healthcare setting. A Federally Qualified Health Center, regenerative farm, and academic institution partnered for the PRx program (2017-21). During harvest seasons, patients redeemed "prescriptions" for initial and "refill" produce boxes...

BACKGROUND: Design thinking is an iterative process that innovates solutions through a person-centric approach and is increasingly used across health contexts. The person-centric approach lends itself to working with groups with complex needs. One such group is families experiencing economic hardship, who are vulnerable to food insecurity and face challenges with child feeding. OBJECTIVE: This study describes the application of a design thinking framework, utilizing mixed methods, including co-design, to develop a responsive child-feeding intervention for Australian families-'Eat, Learn, Grow'...

INTRODUCTION: Poor quality of complementary foods is a key contributor to undernutrition even with optimal breastfeeding. Minimum Acceptable Diet (MAD) has tremendous health and nutrition benefits but only 12% of Ethiopian children's feeding practices meet its standards. The Ethiopian government has recently increased efforts to expand nutrition-sensitive irrigation to improve child nutrition. However, the impact that irrigation has brought on the minimum acceptable diet practice of children below two years has not yet been studied...

The gut-brain peptide ghrelin and its receptor are established as a regulator of hunger and reward-processing. However, the recently recognized ghrelin receptor inverse agonist, liver-expressed antimicrobial peptide 2 (LEAP2), is less characterized. The present study aimed to elucidate LEAP2s central effect on reward-related behaviors through feeding and its mechanism. LEAP2 was administrated centrally in mice and effectively reduced feeding and intake of palatable foods. Strikingly, LEAP2s effect on feeding was correlated to the preference of the palatable food...

Peppers (Piper nigrum L.) are distinguished by their pungent flavor and aroma. Piperine is a major acid-amide alkaloid with a piperidine ring that gives pepper its flavor and scent. In plant metabolomics research, the accessibility of the chemical standards is critical for scientific credibility. We isolated and identified 10 novel dimers of acid amide alkaloids (9-15 and 20-22), along with 12 known monomers (1-6) and dimers (7, 8, 16-19) from black pepper. Subsequently, we found the distribution of monomers and dimers of acid amide alkaloids in black and white peppers by twenty-two acid amide alkaloids which we obtained using the molecular networking technique and multivariate analysis to reveal the molecular relationships between the acid amide alkaloids in black and white peppers...

Cardiovascular devices are essential for the treatment of cardiovascular diseases including cerebrovascular, coronary, valvular, congenital, peripheral vascular and arrhythmic diseases. The regulation and surveillance of vascular devices in real-world practice, however, presents challenges during each individual product's life cycle. Four examples illustrate recent challenges and questions regarding safety, appropriate use and efficacy arising from FDA approved devices used in real-world practice. We outline potential pathways wherein providers, regulators and payors could potentially provide high-quality cardiovascular care, identify safety signals, ensure equitable device access, and study potential issues with devices in real-world practice...

BACKGROUND: High sodium and low potassium intake are positively associated with blood pressure, a significant risk factor for cardiovascular disease. The mean intake of sodium among United States adults exceeds the chronic disease risk reduction level of 2300 mg/d, whereas potassium intake remains lower than the recommended levels. From 2008 through 2019, there were several local and national initiatives to reduce sodium in New York City (NYC). OBJECTIVES: We aimed to update and compare estimates of sodium intake among NYC adults overall and by covariates from the 2010 Heart Follow-Up Study (HFUS) with the 2018 HFUS...

INTRODUCTION: Binge eating disorder (BED) is a widespread eating disorder that primarily affects women worldwide, and it is characterized by the presence of binge eating episodes and the absence of any compensatory behavior to prevent weight gain. BED presents elevated comorbidity with other psychiatric disorders, such as anxiety, and it has been suggested that stress sensibility could be a vulnerability factor for the development of BED and the associated anxiety comorbidity. In this study, we aim to investigate whether the Wistar-Kyoto rat strain (WKY), which has a stress hyper-reactive phenotype, could develop both binge-type eating and anxiety-like behaviors simultaneously...

In December 2023, the US Food and Drug Administration and the UK Medicines and Healthcare Products Regulatory Agency granted the first regulatory approval for genome therapy for sickle cell disease. This approval brings hope to those suffering from this debilitating genetic disease. However, several barriers may hinder global patient access, including high treatment costs, obtaining informed consent for minors, inadequate public health infrastructure, and insufficient regulatory oversight. These barriers reflect the structural inequalities inherent in global health governance, where patient access often depends on social and institutional arrangements...

Passion fruit ( Passiflora spp.) is an important fruit tree in the family Passifloraceae. The color of the fruit skin, a significant agricultural trait, is determined by the content of anthocyanin in passion fruit. However, the regulatory mechanisms behind the accumulation of anthocyanin in different passion fruit skin colors remain unclear. In the study, we identified and characterized a R2R3-MYB transcription factor, PeMYB114 , which functions as a transcriptional activator in anthocyanin biosynthesis. Yeast one-hybrid system and dual-luciferase analysis showed that PeMYB114 could directly activate the expression of anthocyanin structural genes ( PeCHS and PeDFR )...

AIMS: This study describes a program co-created with Aboriginal communities to strengthen cultural ties with the children. Food data are reported from two knowledge systems (lenses): Western and Aboriginal relational, focused on Country, community, and kinship. METHODS: A cultural program was undertaken with primary school children of Aboriginal heritage, on Yuin nation, over 10 weeks including culturally appropriate practices (painting, bushtucker, and dance)...

BACKGROUND: Mastitis, a pervasive and detrimental disease in dairy farming, poses a significant challenge to the global dairy industry. Monitoring the milk somatic cell count (SCC) is vital for assessing the incidence of mastitis and the quality of raw cow's milk. However, existing SCC detection methods typically require large-scale instruments and specialized operators, limiting their application in resource-constrained settings such as dairy farms and small-scale labs. To address these limitations, this study introduces a novel, smartphone-based, on-site SCC testing method that leverages smartphone capabilities for milk somatic cell identification and enumeration, offering a portable and user-friendly testing platform...

BACKGROUND: Faced with the increase in the number of chronic diseases with the aging of the population, and with the observation of the insufficiency of therapeutic control, a new need has emerged, that of having a patient as a partner in care. METHODS: This study is a randomized controlled trial. Patients with coronary heart disease will be recruited from one clinical site and randomly assigned into two groups: the intervention group and the control group. All participants will be followed up for a total of one year (with three-time points for data collection)...

In order to understand the impacts in the post-disaster scenario of the 2017 El Niño events in the Piura region-Peru, we examined post-traumatic stress disorder (PTSD), food insecurity (FI), and social capital (SC) across three-time points in mothers in highly affected areas. In the Piura, Castilla, and Catacaos districts, we studied mothers combining mixed-method assessments at three (June-July 2017), eight and 12 months after the flooding. Each outcome was measured with the PTSD-Checklist-Civilian (PCL-C), the Household-Food-Insecurity-Access-Scale (HFIAS), the Adapted-Social-Capital-Assessment-Tool (SASCAT) surveys...

To prevent obesity and diabetes environmental interventions such as eliminating food deserts, restricting proliferation of food swamps, and improving park access are essential. In the United States, however, studies that examine the food and park access relationship with obesity and diabetes using both global and local regression are lacking. To guide county, state, and federal policy in combating obesity and diabetes, there is a need for cross-scale analyses to identify that relationship at national and local levels...

In many African countries, land access and tenure insecurity pose significant challenges to agriculture, in particular for the youth. As the farming population ages, young people are expected to take over, but they don't often show much interest in farming, which could harm the future of agriculture in Africa, where the population is the youngest. Land reforms and titling programs are suggested as amongst strategies to make agriculture more attractive to investors and promote youth involvement. As a result, majority African countries undertook reforms such as land titling, ownership mapping and market facilitation as policy prescriptions for promoting youth involvement in agriculture...

The presence of Vibrio parahaemolyticus (Vp) in different production stages of seafood has generated negative impacts on both public health and the sustainability of the industry. To further better investigate the fitness of Vp at the phenotypical level, a great number of studies have been conducted in recent years using plate counting methods. In the meantime, with the increasing accessibility of the next generation sequencing and the advances in analytical chemistry techniques, omics-oriented biotechnologies have further advanced our knowledge in the survival and virulence mechanisms of Vp at various molecular levels...
