Urban Partnerships to Address Health Literacy in High Need Populations

Low health literacy disproportionately affects racial and ethnic minority communities and lower-income socioeconomic groups. To address this critical determinant of health inequity, two nonprofit organizations, Repairers of the Breach, a day shelter for individuals experiencing homelessness, and Bread of Healing a neighborhood-based clinic serving individuals with low incomes, partnered with researchers at Marquette University to implement and evaluate an evidence-supported health literacy program. The partnership delivered the curriculum in seven one-hour sessions over seven weeks. The program attendees were predominantly African American men and women from 19–73 years old. Most participants had formal education ranging from elementary school to some college. Forty individuals attended at least one class and 14 attendees completed 4 or more classes. Program completers demonstrated gains in confidence and topic knowledge. Most interviewees reported a personal/family need for the program, acceptability of the group format, and the ability to learn the skills they needed for self-care. The project used a successful collaboration between community-based organizations serving vulnerable populations and an urban academic institution to demonstrate the necessity, feasibility, acceptability, and effectiveness of formal health literacy education in adults with low incomes or who are experiencing homelessness. Urban and metropolitan serving institutions can work in partnership with community to address low health literacy in high need populations

Development and use of “ICP-MS TuneSim”: a software app that allows students to simulate tuning an inductively coupled plasma mass spectrometer

A new app, freely available for Windows computers, has been developed to simulate tuning of an inductively coupled plasma mass spectrometer, on the basis of optimization data collected using a sector-field instrument. The app allows students to adjust parameters, including the torch position, gas flows, radio-frequency power, and guard-electrode state, while observing the signal for three “measured” variables in real time. The app has been used with a group of second-year undergraduate students to supplement theoretical material taught in an Atomic Spectrometry lecture course. The exercise familiarized students with key components of the instrument and demonstrated how multiple factors may need to be balanced when performing optimization

Evaluating Airsoft Electric Guns for Control of Invasive Brown Treesnakes

Firearms are often used in lethal control of invasive vertebrates, but safety and regulatory aspects limit the circumstances under which they can be used. During August 2016 at the Brown Treesnake Project laboratory on Guam, we evaluated hobby‐grade Airsoft Electric Guns (AEGs; a lower powered, less‐hazardous, and less‐regulated alternative to firearms) for capture and control of small animals, with specific emphasis on invasive brown treesnakes (Boiga irregularis). Tests of AEGs differing in power with ammunition (plastic pellets) masses ranging from 0.20 to 0.39 g, fired at gelatin blocks from distances of 4, 8, and 12 m, showed that heavy ammunition is of overriding importance for maximizing lethality: 0.39‐g pellets penetrated more deeply at 12 m than did 0.20‐g pellets at 4 m. Inspection of tissue damage in brown treesnake carcasses subjected to fire with the 0.39‐g ammunition from the same distances suggested that injuries sustained by a direct hit from 12 m would often be lethal, and snakes would be unlikely to survive multiple hits from automatic fire discharged at approximately 17/s. Limited trials with live snakes helped us to understand behavioral responses in a snake hit by ≥1 pellets, including distance traveled over time. Based on these factors, we assessed the risk that a snake injured by pellet fire might evade subsequent capture by rapid responders in the proximity. We also discuss ethical considerations and regulatory advantages of using AEGs

Long-term athletic training does not alter age-associated reductions of left-ventricular mid-diastolic lengthening or expansion at rest

Purpose: The interaction of ageing and exercise training status on left-ventricular (LV) peak strain is unclear. Additionally, strain analysis across the entire cardiac cycle facilitates a more detailed assessment of deformation, yet this has not been implemented to characterize the ageing LV and in association with training status. This study investigated healthy ageing and training status on LV systolic and diastolic strain utilizing novel echocardiographic applications. Methods: Forty healthy males were included and allocated into four groups; young recreationally active (YRA,n = 9; 28 ± 5 years), old recreationally active (ORA, n = 10; 68 ± 6), young trained (YT,n = 10; 27 ± 6 years), and old trained (OT, n = 11, 64 ± 4 years) groups. Two-dimensional speckle-tracking echocardiography was performed to ascertain peak LV longitudinal and circumferential strain (base and apex) strain within each myocardial layer and at 5% increments across the cardiac cycle. Results: Older groups had lower diastolic longitudinal lengthening and circumferential expansion between 40–85% mid-diastole, regardless of training status (P 0.05). Longitudinal and circumferential (base and apex) peak and layer-specific strain did not differ between groups (P > 0.05). Conclusion: Novel applications of diastolic strain revealed lower age-associated LV longitudinal lengthening and circumferential expansion in older age. Yet, diastolic strain profiles did not differ based on chronic habits of exercise training and, thus, older trained men did not demonstrate an attenuation of age-associated differences in mid-diastolic LV strain. © 2020, The Author(s)

Flint’s Children: Narratives on Hope

Hope plays an important role in resiliency, well-being, and buffering against adversity. To explore children’s experiences with hope while developing in low-income communities, we conducted interviews with twenty-one children residing in Flint, Michigan, ages 9-12 years. Research questions focused on the specific hopes children have, the importance they ascribe to different hopes, and their experiences of feeling hopeful or less hopeful about desired outcomes. Children expressed interrelated hopes across multiple social-ecological domains, including hopes for themselves, hopes for their interpersonal relationships, and hopes for the community. Children placed particular importance on their hopes of helping others, which included providing for their families and aiding others in the community. Children, however, expressed uncertainty regarding their hopes related to career aspirations, academic achievement, financial stability, and obtaining basic needs. Our findings expand upon what is known about children’s internal dialogues with feeling hopeful or less hopeful about desired outcomes in low-income communities. These findings can enhance community and school-based programming so they further align with the specific hopes that children have, and attune to areas in which children in impoverished communities are most in need of hope-engendering strategies

The influence of age and exercise training status on left ventricular systolic twist mechanics in healthy males—an exploratory study

Age-related differences in twist may be mitigated with exercise training, although this remains inconclusive. Moreover, temporal left ventricular (LV) systolic twist mechanics, including early-systolic (twistearly), and beyond peak twist (twistpeak) alone, have not been considered. Therefore, further insights are required to ascertain the influence of age and training status on twist mechanics across systole. Forty males were included and allocated into 1 of 4 groups based on age and training status: young recreationally active (YRA, n = 9; 28 ± 5 years), old recreationally active (ORA, n = 10; 68 ± 6 years), young trained (YT, n = 10; 27 ± 6 years), and old trained (OT, n = 11, 64 ± 4 years) groups. Two-dimensional speckle-tracking echocardiography was performed to determine LV twist mechanics, including twistearly, twistpeak, and total twist (twisttotal), by considering the nadir on the twist time-curve during early systole. Twisttotal was calculated by subtracting twistearly from their peak values. LV twistpeak was higher in older than younger men (p = 0.036), while twistpeak was lower in the trained than recreationally-active (p = 0.004). Twistpeak is underestimated compared with twisttotal (p < 0.001), and when early-systolic mechanics were considered, to calculate twisttotal, the age effect (p = 0.186) was dampened. LV twist was higher in older than younger age, with lower twist in exercise-trained than recreationally-active males. Twistpeak is underestimated when twistearly is not considered, with novel observations demonstrating that the age effect was dampened when considering twistearly. These findings elucidated a smaller age effect when early phases of systole are considered, while lower LV systolic mechanics were observed in older aged trained than recreationally-active males

A mixed methods study to inform fatal overdose prevention in San Diego, California: perspectives from people who use drugs

Background: In the United States, community overdose education and naloxone distribution (OEND) programs have demonstrated efficacy in reducing opioid-related mortality. OEND programs have expanded across San Diego County, California, but differential naloxone accessibility among people who use drugs (PWUD) has not been assessed. We examined factors that shape individual naloxone accessibility in San Diego.Methods: We employed a convergent parallel mixed methods design using surveys (n=194) and qualitative interviews (n=20). Ordinal logistic regression examined factors associated with personal naloxone accessibility (i.e., the frequency with which participants could access naloxone within five minutes, categorized as never, sometimes, or always). Qualitative interviews explored participant perceptions of naloxone accessibility and whether and how they maintained naloxone. We organized multilevel findings into a modified social-ecological model.Results: In quantitative and qualitative samples, participants were majority male (72% and 70% respectively), non-White race/ethnicity (55% and 75%), with an average age around 42 years. In the quantitative sample, 24% never had personally accessible naloxone, 52% sometimes did, and 24% always did. Factors independently associated with greater personal naloxone accessibility were female gender (Adjusted Odds Ratio [AdjOR]: 2.51, 95% Confidence Interval [CI]: 1.31–4.85), monthly income <$500 (AdjOR: 0.42, 95%CI:0.19, 0.90), witnessing an overdose (AdjOR: 3.51, 95%CI:1.67–7.55), and knowing where to get free naloxone (AdjOR: 3.44, 95%CI: 1.79–6.75). Qualitative data suggested that naloxone was generally easy to acquire in San Diego due to community harm reduction outreach and mutual aid among peers, albeit community barriers including distance to harm reduction providers and frequent relocation/displacement for those experiencing homelessness. Individual attitudes toward overdose risk, naloxone, and community responsibility contributed to varied individual naloxone accessibility.Conclusions: This study highlights multilevel factors influencing personal naloxone accessibility among people who use drugs in San Diego, emphasizing the importance of harm reduction outreach and peer-to-peer support. We identified opportunities for interventions that address both individual attitudes and community-level barriers to improve naloxone accessibility

Gone with the wind: dune provenance and sediment recycling in the northern Rub’ al-Khali, United Arab Emirates

The Rub’al-Khali dune field in southern Arabia is the largest sand sea in the world. Deciphering thepalaeoenvironmental history of the Rub’al-Khali is critical to understanding its role as a barrier to human migration, dispersaland settlement. To determine sediment provenance and transport pathways, we combined data from a geological mappingproject with traditional heavy mineral optical point-counting methods, heavy mineral geochemical fingerprinting and detritalzircon U–Pb geochronology of Miocene and Quaternary sediments in the United Arab Emirates (UAE). Detrital zircon U–Pbage spectra demonstrate that most Neogene and Quaternary sediments in the UAE are ultimately sourced from the PrecambrianArabian Shield. Heavy mineral and geochemical signatures indicate that the dune sands are locally recycled from the deflationof Miocene sandstones and Quaternary siliciclastic palaeodunes exposed along the Arabian Gulf coast, whereas carbonatepalaeodunes along the Gulf coast are derived from the deflation of sediments deposited by the Tigris–Euphrates River system inthe Gulf during Pleistocene lowstands. In the eastern Emirates, Miocene and Quaternary alluvial fan deposits emanating fromthe Hajar Mountains have an ophiolitic heavy mineral signature. The data reveal new insights into the origin and developmentof the Rub’al-Khali dune field
