Background: Global food systems are essential to sustain life; however, unhealthy diets are the leading cause of poor health and death worldwide. Natural food environments are a critical source of healthful food such as fresh fruit and vegetables, lean meat and aquatic foods, particularly in low- and middle-income countries (LMICs) and Indigenous food systems. Understanding and monitoring natural food environments is critical to protecting the supply of healthy food, and the land and water it comes from, for current and future generations.

There are calls for governments around the world to adopt pricing policies, including taxes, subsidies and price controls that ensure all people have access to, and can afford, healthy diets. Despite the strong potential of pricing policies to promote healthy diets and to support a post-COVID-19 recovery, there are gaps in evidence with regard to 'how' to design and apply effective food taxes in practice, and countries report challenges in navigating the different policy options.In this practice piece, we examine the global evidence for food taxes with a view to identifying practical lessons for policy design, adoption and implementation, using the Pacific Islands Region as a case study.

In Solomon Islands, the retail food environment is an important food source, for instance, the dominant source of fresh fruit and vegetables for urban consumers is open markets. The effects of COVID-19 mitigation measures (such as restriction of human movement and border closures) in early 2020 placed food security at risk in many parts of the community. Of particular concern was the risk of price gouging in an already price-sensitive market.

Adults presenting with transverse maxillomandibular discrepancies in Class III skeletal patterns, asymmetries and anterior open bite can be challenging to treatment plan and manage. Therefore, they often necessitate a multidisciplinary approach, with surgical input from the oral and maxillofacial team. It can be difficult to assess how much the maxilla needs to be expanded after surgery in these patients, as the upper and lower teeth cannot be brought into occlusion.

Preventing noncommunicable diseases is a global priority, for which the World Health Organization has recommended policies to reduce the consumption of tobacco products, alcohol and unhealthy foods. However, regulation has been strongly opposed by affected industries, who have invoked the provisions of legally binding trade and investment agreements. The aim of this analysis of the legal, economic and public health literature was to present a short primer on the relationship between noncommunicable disease prevention policy and trade and investment agreements to help public health policy-makers safeguard public health policies.

Black individuals are less likely to receive an accurate diagnosis of mild cognitive impairment (MCI) than their White counterparts, possibly because diagnoses are typically made by a physician, often without reference to objective neuropsychological test data. We examined racial differences in actuarial MCI diagnoses among individuals diagnosed with MCI via semi-structured clinical interview (the Clinical Dementia Rating) to examine for possible biases in the diagnostic process. Participants were drawn from the National Alzheimer's Coordinating Center Uniform Data Set and included 491 individuals self-identifying as Black and 2,818 individuals self-identifying as White.

Black adults are diagnosed with Alzheimer's disease (AD) at higher rates than White adults. Biopsychosocial risk factors that differentially affect individuals by race, including health, education, and APOE e4, may explain these findings. Some research suggests that the risk for AD associated with the APOE e4 allele may differ by race.

Introduction: Both symptoms and functional impairment should be assessed in college students seeking evaluations for Attention Deficit Hyperactivity Disorder (ADHD). However, impairment is not specific to ADHD. Although it is well documented that self-reported symptoms can be reported noncredibly, there is less research examining credibility of self-reported impairment, and few clinicians rule out alternative causes for impairment.

Ischemic events, common in many diseases, result from decreased blood flow and impaired delivery of oxygen and glucose to tissues of the body. While much is known about the cellular transcriptional response to ischemia, much less is known about the posttranscriptional response to oxygen and glucose deprivation. The goal of this project was to investigate one such posttranscriptional response, the regulation of mRNA stability.

Previous research has demonstrated that older adults are not as accurate as younger adults at perceiving negative emotions in facial expressions. These studies rely on emotion recognition tasks that involve choosing between many alternatives, creating the possibility that age differences emerge for cognitive rather than perceptual reasons. In the present study, an emotion discrimination task was used to investigate younger and older adults' ability to visually discriminate between negative emotional facial expressions (anger, sadness, fear, and disgust) at low (40%) and high (80%) expressive intensity.
