Cultivating community-based participatory research (CBPR) to respond to the COVID-19 pandemic: an illustrative example of partnership and topic prioritization in the food services industry.

Background: As an illustrative example of COVID-19 pandemic community-based participatory research (CBPR), we describe a community-academic partnership to prioritize future research most important to people experiencing high occupational exposure to COVID-19 - food service workers. Food service workers face key challenges surrounding (1) health and safety precautions, (2) stress and mental health, and (3) the long-term pandemic impact.

Method: Using CBPR methodologies, academic scientists partnered with community stakeholders to develop the research aims, methods, and measures, and interpret and disseminate results.

Impulsive, Disinhibited Behavior-Dining in a Restaurant.

Dining in a restaurant with a loved one who has dementia can be an ordeal, especially if the expectations of the caregiver do not match those of the patient and the restaurant environment is not suitable for patients with dementia. The size of the dining area, lighting, background music or noise, décor of the room, number of customers, variety of the items on the menu, number of plates and cutlery on the table, in addition to flowers, candles, and other decorations on the table are all potent distractors. There are so many stimuli; the patient can be overwhelmed with information overload and not able to focus on the main purpose of the event: have dinner and especially enjoy the other person's company.

Phenolic-rich extract from the Costa Rican guava (Psidium friedrichsthalianum) pulp with antioxidant and anti-inflammatory activity. Potential for COPD therapy.

The potential therapeutic effects of Costa Rican guava (Psidium friedrichsthalianum) extracts for chronic obstructive pulmonary disease were examined. The ethyl acetate fraction displayed the highest antioxidant activity, as compared to the hexane, chloroform, and n-butanol fractions, as well as the crude extract. This fraction was evaluated for its anti-inflammatory activity response relationship against interleukin-8 (IL-8) and inhibition of matrix metalloproteinase-1 (MMP-1) expression before and after treatment with cigarette smoke.

Anthocyanins from Eugenia brasiliensis edible fruits as potential therapeutics for COPD treatment.

Nine anthocyanins (1-9) from the edible fruits of Eugenia brasiliensis were identified by HPLC-PDA and LC-MS, and seven of these are described for the first time in this Brazilian fruit. Two of the major anthocyanins, delphinidin (8) and cyanidin (9), were studied for their inhibitory activity against chemokine interleukin-8 (IL-8) production before and after cigarette smoke extract (CSE) treatment of cells. In non-treated cells the amount of IL-8 was unchanged following treatment with cyanidin and delphinidin in concentrations 0.

Edible Myrciaria vexator fruits: bioactive phenolics for potential COPD therapy.

The edible fruits of Myrciaria vexator McVaugh (Myrtaceae), from northern South America, are eaten in certain locales, either fresh or processed into jellies and drinks. Activity-guided fractionation of M. vexator resulted in identification of ellagic acid (1), cyanidin-3-O-glucoside (2), delphinidin-3-O-glucoside (3), 2-O-(3,4-dihydroxybenzoyl)-2,4,6-trihydroxyphenylacetic acid (4), and jaboticabin (5), and latter two compounds are being reported for the first time in this species.

Antioxidants of therapeutic relevance in COPD from the neotropical blueberry Anthopterus wardii.

Four flavone C-glycosides, isoorientin (1), orientin (2), vitexin (3), and isovitexin (4), were isolated from the neotropical blueberry of Anthopterus wardii, a so-called "superfruit", using antioxidant activity-guided fractionation. A dose-response relationship of compounds 1-4 was determined for their anti-inflammatory activity against interleukin-8 (IL-8) and for the inhibition of matrix metalloproteinase-1 (MMP-1) expression, an inflammatory marker for chronic obstructive pulmonary disease. The four flavone C-glycosides exhibited inhibitory activity against IL-8 production and MMP-1 expression, with compounds 1, 3, and 4 having the most potent inhibitory activities in both assays at 100 μg/ml.

Work-related stressors experienced by part-time clinical affiliate nursing faculty in baccalaureate education.

This descriptive and multivariate correlational study identifies work-related situations that were perceived as stressful in a sample of part-time clinical affiliate nursing faculty (n = 91) from a western state who teach in baccalaureate programs. The most stressful conditions include being physically and emotionally drained; working outside regular hours; dealing with the number of role expectations; and receiving inadequate monetary compensation. Subjects reported other specific stressful situations related to their work with clinical agencies, universities, and students.
