Functional Reach and Gait Speed Improvement in A Matter of Balance Participants.

BACKGROUND: Falls among older adults are the most common cause of hospital admissions. A Matter of Balance may reduce these falls by improving balance, flexibility, gait speed, and agility. OBJECTIVE: The study aimed to measure functional reach and gait speed among adults older than 65 years following A Matter of Balance. It was hypothesized that functional reach scores would increase and gait speed scores would decrease. METHODS: This was an interventional study with the primary outcomes of functional reach (measured by the Functional Reach test) and gait speed (measured by the Timed Up and Go test). A one-tailed paired t test was used to compare pre- and postprogram functional reach mean differences. A one-tailed Wilcoxon signed-rank test was used for comparing median differences of pre- and postprogram gait speed. Characteristics of participants who improved scores were compared with those who did not improve, using two-tailed independent-samples t tests and two-tailed Pearson's χ2. Effect sizes were computed for tests significant beyond p < .05. RESULTS: Mean functional reach increased by 0.6 inches (SD = 2.21, p = .002; d = 0.2). Median gait speed decreased by 1.25 s (interquartile range = 2.39, p < .001; r = .76). Improvement was not attributable to differences of age, sex, health status, preexisting conditions, or delivery site. CONCLUSIONS: Following A Matter of Balance, functional reach and gait speed improved. Adults older than 65 years should be encouraged to participate in the program, as it may reduce their fall risk.

Prioritizing Injury Prevention: Cause of Injury Text Analysis.

BACKGROUND: Motor vehicle (MVCs) and motorcycle crashes (MCCs) continue to be among the most prevalent mechanisms of trauma injury and mortality. We sought to identify specific populations and factors associated with MVCs and MCCs for local injury prevention efforts. A novel, yet easily performed, research method was utilized-a qualitative content analysis of text narratives describing each patient's cause of injury. OBJECTIVE: To determine target populations for local MVC and MCC injury prevention. METHODS: A retrospective descriptive analysis was performed using registry data from a Level I trauma center. The registry was queried for all trauma patients presenting with MVC or MCC injuries between June 8, 2014, and June 7, 2019. Cases were then reviewed via their respective text narratives of injury causation. Common themes were identified, coded by independent raters, and assessed for interrater reliability using Cohen's κ. Frequencies and proportions are reported for each preventable factor and patient characteristic. RESULTS: There were a total of 2,861 cases studied, of which 2,330 (81.4%) were MVC and 531 (18.6%) were MCC. Demographics varied by mechanism of injury. Driver drug or alcohol use was involved in 97 (3.4%), protective devices were not used in 776 (27.1%), distracted driving was involved in 30 (1%), excessive speeding was involved in 152 (5.3%), and driver sleeping/syncope/medical condition was present in 113 (3.9%) cases. CONCLUSIONS: Content analysis of cause of injury text narratives can detect target populations and preventable factors to direct injury prevention efforts specific to the local population.

Comparative compositions of grain of tritordeum, durum wheat and bread wheat grown in multi-environment trials.

Three genotypes each of bread wheat, durum wheat and tritordeum were grown in randomized replicated field trials in Andalusia (Spain) for two years and wholemeal flours analysed for a range of components to identify differences in composition. The contents of all components that were determined varied widely between grain samples of the individual species and in most cases also overlapped between the three species. Nevertheless, statistically significant differences between the compositions of the three species were observed. Notably, tritordeum had significantly higher contents of protein, some minerals (magnesium and iron), total phenolics and methyl donors. Tritordeum also had higher levels of total amino acids (but not asparagine) and total sugars, including raffinose. By contrast, bread wheat and tritordeum had similar contents of the two major dietary fibre components in white flour, arabinoxylan and ß-glucan, with significantly lower contents in durum wheat.

Comparative Compositions of Grain of Bread Wheat, Emmer and Spelt Grown with Different Levels of Nitrogen Fertilisation.

Five cultivars of bread wheat and spelt and three of emmer were grown in replicate randomised field trials on two sites for two years with 100 and 200 kg nitrogen fertiliser per hectare, reflecting low input and intensive farming systems. Wholemeal flours were analysed for components that are suggested to contribute to a healthy diet. The ranges of all components overlapped between the three cereal types, reflecting the effects of both genotype and environment. Nevertheless, statistically significant differences in the contents of some components were observed. Notably, emmer and spelt had higher contents of protein, iron, zinc, magnesium, choline and glycine betaine, but also of asparagine (the precursor of acrylamide) and raffinose. By contrast, bread wheat had higher contents of the two major types of fibre, arabinoxylan (AX) and ß-glucan, than emmer and a higher AX content than spelt. Although such differences in composition may be suggested to result in effects on metabolic parameters and health when studied in isolation, the final effects will depend on the quantity consumed and the composition of the overall diet.

The effect of soil type on yield and micronutrient content of pasture species.

The use of multispecies swards on livestock farms is growing due to the wide range of benefits they bring, such as improved biomass yield and animal performance. Preferential uptake of micronutrients by some plant species means the inclusion of legumes and forbs in grass-dominated pasture swards could improve micronutrient provision to livestock via careful species selection. However, although soil properties affect plant micronutrient concentrations, it is unknown whether choosing 'best-performing' species, in terms of their micronutrient content, needs to be soil-specific or whether the recommendations can be more generic. To address this question, we carried out an experiment with 15 common grass, forb and legume species grown on four soils for five weeks in a controlled environment. The soils were chosen to have contrasting properties such as texture, organic matter content and micronutrient concentrations. The effect of soil pH was tested on two soils (pH 5.4 and 7.4) chosen to minimise other confounding variables. Yield was significantly affected by soil properties and there was a significant interaction with botanical group but not species within a botanical group (grass, forb or legume). There were differences between botanical groups and between species in both their micronutrient concentrations and total uptake. Micronutrient herbage concentrations often, but not always, reflected soil micronutrient concentrations. There were soil-botanical group interactions for micronutrient concentration and uptake by plants, but the interaction between plant species (within a botanical group) and soil was significant only for forbs, and predominantly occurred when considering micronutrient uptake rather than concentration. Generally, plants had higher yields and micronutrient contents at pH 5.4 than 7.4. Forbs tended to have higher concentrations of micronutrients than other botanical groups and the effect of soil on micronutrient uptake was only significant for forbs.
