Sustainable healthy diets are those dietary patterns that promote all dimensions of individuals' health and well-being; have low environmental pressure and impact; are accessible, affordable, safe, and equitable; and are culturally acceptable. The food environment, defined as the interface between the wider food system and consumer's food acquisition and consumption, is critical for ensuring equitable access to foods that are healthy, safe, affordable, and appealing. Current food environments are creating inequities, and sustainable healthy foods are generally more accessible for those of higher socioeconomic status. The physical, economic, and policy components of the food environment can all be acted on to promote sustainable healthy diets. Physical spaces can be modified to improve relative availability (ie, proximity) of food outlets that carry nutritious foods in low-income communities; to address economic access certain actions may improve affordability, such as fortification, preventing food loss td loss through supply chain improvements; and commodity specific vouchers for fruits, vegetables, and legumes. Other policy actions that address accessibility to sustainable healthy foods are comprehensive marketing restrictions and easy-to-understand front-of-pack nutrition labels. While shaping food environments will require concerted action from all stakeholders, governments and private sector bear significant responsibility for ensuring equitable access to sustainable healthy diets. To perform a systematic study about the contribution of architecture and interior design researchers in studying the effect of physical environment on mental disorders. Mental disorders are a major health problem worldwide and related to severe distress, functional disabilities, and heavy economical burdens. Studies propose that physical environment design can trigger or reduce mental disorder symptoms. However, there is a lack of knowledge about the extent of architectural design research contribution to all types of mental disorder prevention or intervention. A team of cross-disciplinary researchers gathered information from peer-reviewed manuscripts about the effect of architectural design on enhancing or reducing mental disorder symptoms. Data were collected from manuscripts published between 2008 and 2020 (research related to the topic became clearer in quality and quantity then). Keywords including architecture, interior design, physical environment, and mental disorders were used in the systematic search. Databases were collected using online resources. Numerical data collected from quantitative studies were organized in tables. Our data showed that there were a lot of studies about dementia and autism; few studies about schizophrenia, anxiety, stress-related disorders, and depressive disorders; and no studies about the rest of the mental disorders. General environment followed by housing facility design were the most assessed physical environments for mental disorders. As all mental disorders can have a significant impact on the society, we conclude that architectural studies should focus more on improving or preventing the symptoms of all types of mental disorders through the design of physical environments.

Several β-carotenoids have been inversely associated with breast cancer risk, but association by type of tumor and participant characteristics remain nuclear. The objective of this review of epidemiological studies is to investigate the relationship between β-carotenoids and breast cancer. This review covers the 2014-2020 period and was carried out using the PubMed and EMBASE databases. Only epidemiological studies carried out on β-carotenoids and breast cancer were included. The initial keyword search yielded 1559 results and finally a total of 28 studies were included. The quality of the articles and the risk of bias for each included article were assessed. The selected articles were subsequently classified according to their quality. The evidence from the included studies confirms that there is an association between β-carotenoids and breast cancer risk; the dietary intake of β-carotenoids may be beneficial in reducing the risk of developing breast cancer. Peripheral nerve injury is a common clinical disorder. The aim of the present study was to investigate the role of cerium oxide nanoparticles on axonal regeneration and functional recovery of the sciatic nerve after a crush injury in the rat model. A total of 40 adult male Wistar rats were divided into four groups. The animals underwent deep anesthesia. Afterward, the right sciatic nerve of rats was exposed and crushed. https://www.selleckchem.com/PARP.html In two experimental groups, rats were treated intraperitoneally with cerium oxide nanoparticles at the dosage of 20 or 80 mg/kg daily for 1 week. The control group was given a vehicle. Then, during the nerve regeneration motor and sensory function recovery tests, histomorphometric evaluations, histological assessment of gastrocnemius muscle, and gastrocnemius muscle wet weights tests were performed. Results demonstrated that the rate of nerve regeneration increased with the administration of cerium oxide nanoparticle in high doses. Also, the morphometric analysis showed that the number of myelinated fibers and myelin sheath thicknesses was significantly greater in the cerium oxide nanoparticle group versus the control group. Other parameters also improved in the cerium oxide nanoparticle treatment groups compared with the control group. These data indicate that this nanoparticle has therapeutic potential and can be considered as a new treatment for nervous system regeneration. These data indicate that this nanoparticle has therapeutic potential and can be considered as a new treatment for nervous system regeneration.Issue Epistemology, the branch of philosophy that deals with the nature, value, and use of knowledge, receives little or no formal attention in medical education. Yet the understanding of medical epistemology - focused on what kinds of medical knowledge are relevant to clinical decisions, the strengths and limitations of those different kinds of knowledge, and how they relate to one another and to clinical expertise - represents a critical aspect of medical practice. Evidence Understanding the meaning of the term "evidence" is one of the fundamental tasks of medical epistemology. Other foundations of the evidence-based medicine movement, such as the "hierarchy of evidence" and the concept of "best" evidence, rest upon epistemological assertions, claims regarding the appropriate kinds and relative value of knowledge in medicine. Here we rely upon the work of philosophers of medicine who have been engaged in debates regarding the epistemic tenets of the evidence-based medicine movement. We argue that medical students and physicians-in-training should learn basic terminology and methods of epistemology as they are being introduced to the concepts and techniques of evidence-based medicine.
