It is plausible to assume that healthcare practitioners do not know to what extent bed/body alarms could reduce falls when compared to other fall prevention measures. Thus, the purpose of this study was to determine the following: Do bed/body alarms reduce the incidence of falls and/or subsequent injuries in a facility that uses such devices, as compared to a facility in which no bed/body alarms were used among the elderly over a 5-month period? A retrospective chart review was conducted in 2 homogenous long-term care facilities. The sample size was N = 160 across the 2 facilities and included 80 residents at each facility. Analysis of the data indicated that there was a total of 94 falls in the facility that used the bed/body alarms, and a total of 70 falls in the facility that did not use the bed/body alarms. Further analysis of the data indicated that there was a slightly higher mean for falls with injuries within the facility that did use the bed/body alarms (M = 18.800) as compared to a mean of 14.0 for the facility that did not use the bed/body alarms (p = .001). The analysis of data suggested that the use of bed/body alarms did not reduce falls within the elderly population. However, since response time to the alarms was not noted, it is plausible to assume that reduction in falls could have been achieved if response time was also studied as an intervening variable.

Supplemental Digital Content is available in the text., Background: Long-term right ventricular (RV) pacing leads to heart failure or a decline in left ventricular (LV) function in up to a fifth of patients. We aimed to establish whether patients with focal fibrosis detected on late gadolinium enhancement cardiovascular magnetic resonance (CMR) have deterioration in LV function after RV pacing. Methods: We recruited 84 patients with LV ejection fraction ≥40% into 2 observational CMR studies. Patients (n=34) with a dual-chamber device and preserved atrioventricular conduction underwent CMR in 2 asynchronous pacing modes (atrial asynchronous and dual-chamber asynchronous) to compare intrinsic atrioventricular conduction with forced RV pacing. Patients (n=50) with high-grade atrioventricular block underwent CMR before and 6 months after pacemaker implantation to investigate the medium-term effects of RV pacing. Results: The key findings were (1) initiation of RV pacing in patients with fibrosis, compared with those without, was associated with greater immediate changes in both LV end-systolic volume index (5.3±3.5 versus 2.1±2.4 mL/m2; P1.1 g of fibrosis with 90% sensitivity and 70% specificity. Conclusions: Fibrosis detected on CMR is associated with immediate- and medium-term deterioration in LV function following RV pacing and could be used to identify those at risk of heart failure before pacemaker implantation.

Permanent pacemaker (PPM) implantation is an increasingly common procedure with complication rate estimated between 3% and 6%. Cardiac perforation by pacemaker lead(s) is rare, but a previous study has shown that it is probably an underdiagnosed complication. We are presenting a case of a patient who presented 5 days after PPM insertion with new-onset pleuritic chest pain. She had a normal chest X-ray (CXR), and acceptable pacing checks. However, a CT scan of the chest showed pneumopericardium and pneumothorax secondary to atrial lead perforation. The pain only settled by replacing the atrial lead. A repeat chest CT scan a few months later showed complete resolution of the pneumopericardium and pneumothorax. We believe that cardiac perforation can be easily missed if associated with normal CXR and acceptable pacing parameters. Unexplained chest pain following PPM insertion might be the only clue for such complication, although it might not always be present.

News from the RECs At Hansen Agricultural REC, better blackberries and a soil disinfestation alternative Hazel White A t 27 acres, Hansen Agricultural Research and Extension Center (HAREC), in Ventura County, is small. It is exposed to the Santa Ana winds and has heavy clay loam soil infested with one of the highest levels of Verticillium wilt fungus recorded anywhere in the state. And yet it’s proving a major resource for Central Coast growers interested in producing a very profitable blackberry crop or in managing soil pests in strawberries without fumigation. HAREC has developed a growing program for a firm, sweet, large blackberry to produce a good yield during a high-prices sales window in late summer and fall. UC Cooperative Extension (UCCE) Farm Advisor Oleg Daugovish, in charge of berry research, is also contributing to the in- ternational knowledge bank on anaerobic soil disinfestation (ASD), an alternative to chemical fu- migation that uses waste carbon products, such as rice bran. Growers of high-value organic strawber- ries in the Central Coast region have taken up ASD enthusiastically. Prime-Ark 45 blackberry In fall 2011, a new, publicly available primocane blackberry variety, Prime-Ark 45, from the Uni- versity of Arkansas fruit breeding program was planted at HAREC. “It looked good, tasted good, and yielded well,” Daugovish recalls. Since then he has established how to manipulate the timing of the harvest, working with UCCE researchers with blackberry trials under way in other parts of the coast: Mark Bolda, UCCE Director and Farm Advisor in Santa Cruz County, and Mark Gaskell, UC Small Farms Program Advisor in San Luis Obispo and Santa Barbara counties (Gaskell and Daugovish 2016). “Our results are consistent and add up to the same story,” says Daugovish. “This is a high-quality crop, easy to manage, and fruiting can be optimized for the lucrative window in late summer.” Oleg Daugovish Timing the California blackberry harvest for late summer, when berries from other sources are scarce, helps growers maximize returns. 104 CALIFORNIA AGRICULTURE • VOLUME 70 , NUMBER 3

Craft has been accused of ‘discontinuity’ (Greer, 2006), simply producing objects to be looked at rather than used. This paper suggests that there is a role for craft practitioners and craft thinkers in the world of interactive technologies. By focusing on new roles for jewellery and through discussion surrounding issues related to this new role, the research proposes that a synthesis between interactive technologies and craft creates a new space for craft and a new method of research practice.Research into wearable computing in the 1990s led by design labs such as Philips and IBM, envisioned clothes and jewellery which would enable communication and entertainment systems to be integrated into clothing and jewellery. The mode and purpose of wearing jewellery make it an appropriate choice as a controlling device in physical computing (Wallace and Dearden, 2005). The challenge for the craftsperson is to demonstrate that craft thinking can add to the field of interaction design through the applicatio...
