Vascular Flora of E. C. Hafer Park, Edmond, Oklahoma

E. C. Hafer Park is located on the western edge of the Cross Timbers ecoregion, in central Oklahoma within the City of Edmond. The park contains post oak-blackjack oak forest, tallgrass prairie, riparian forest, and areas developed for recreational activities. A vascular plant inventory conducted during 2013, 2015, 2016, and 2017 yielded 270 species in 190 genera and 65 families. The largest families were the Asteraceae (46 species), Poaceae (42), and Fabaceae (27). There were 96 annuals, four biennials, and 170 perennials. Sixty species (22.2%) were not native to the United States. No rare species currently being tracked by the Oklahoma Natural Heritage Inventory were present. Compared to floristic inventories for other sites of similar size in Oklahoma, Hafer Park has a relatively high number of species. However, it also has a relatively high percentage of exotic species from other continents, some of which are invasive and are threatening the native forest, grassland, and riparian plant communities

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Critic's Choice Essay - Take time to watch, not just smell the wildflowers!

Although plant-pollinator interactions between orchids and bees in the tropics may seem more interesting than those closer to home, Oklahoma is full of fascinating plant-pollinator interactions and mechanisms

Tribute to John Taylor

It’s no wonder that the Taylors have been responsible for the identification and distribution information of more native Oklahoma species than anyone else, worldwide; John loved working in the field more than anything else he did. He and Connie traveled extensively and exhaustively throughout their careers. He was active in the Oklahoma Academy of Science and Oklahoma Native Plant Society and Connie, even in her retirement, continues her active participation in these organizations

Critic's Choice Essay - Pollination Ecology of Our Native Prairie Plants

The Oklahoma prairie in the summer is an ideal place and time to study pollination ecology. With its "cornucopia" pattern of flowering, where many plants flower synchronously, it has many flowers available every day. This past summer at the Oklahoma Department of Wildlife Conservation's Arcadia Conservation Education Area, Dr. Rebecca Pace, an entomologist, and I taught a course in pollination ecology for the University of Central Oklahoma

Vascular Flora of Alabaster Caverns State Park, Cimarron Gypsum Hills, Woodward County,Oklahoma

Alabaster Caverns State Park is located in the Cimarron Gypsum Hills of northwestern Oklahoma, a semi-arid region of the state. The majority of the park is dominated by mixed-grass prairie and gypsum outcrops, with some riparian habitat and wooded north-facing slopes. A vascular plant inventory conducted from 2004 through 2007 yielded 274 species in 199 genera and 66 families. The largest families were the Poaceae (52 species), Asteraceae (47), and Fabaceae (23). There were 100 annuals, 6 biennials, and 163 perennials, as well as 5 species that have more than one life history form. Forty-two species (15.3%) were not native to North America. Three taxa currently being tracked by the Oklahoma Natural Heritage Inventory (2012) were present: Echinocereus reichenbachii (S3G5), Haploesthes greggii (S1G4?), and Marsilea vestita (S1G5). Compared to floristic inventories of sites in the Cimarron Gypsum Hills that are less impacted by public visitation, but more intensively grazed, Alabaster Caverns State Park has a higher number of species as well as a higher proportion of introduced species
