Abstract
WHAT IS KNOWN AND OBJECTIVES Obstetrics services are a high-throughput and high-risk environment poised for pharmacist involvement, but determining how to ideally allocate services is difficult. There is recent interest in the development of tools for service prioritization, but none are specifically targeted to obstetrics. Therefore, the aim of this study was (i) to conduct a practice audit surveying the demographics of patients attending obstetrics wards at a high-capacity maternity hospital; and (ii) to evaluate a triage tool developed to prioritize pharmacy services. METHODS A retrospective case review of women discharged after birth admissions was undertaken at a hospital in National Health Service (NHS) Scotland during June 2014. Demographic and admission data were collected, as well as pharmacist interventions and missed opportunities in patient care on post-natal wards. A pharmacy triage tool was developed and retrospectively applied to each case to ascertain a risk category that would trigger and target pharmacist review. Interventions/opportunities were classified as either clinical (medication related) or administrative (potential for error development). RESULTS AND DISCUSSION One hundred and seventy-five cases were reviewed with a median age of 29 years old. Eighty-six patients (49·1%) were retrospectively classified with elevated risk using the triage tool. A total of 117 charts (66·9%) were identified with missed opportunities for pharmacist intervention, which was significantly greater among patients classified as higher risk (75·6 vs. 58·4%, P = 0·017). Compared to low-risk patients, patients with a higher-risk classification had lower rates of administrative missed opportunities (55·4 vs. 80·8%, P = 0·015), but numerically higher rates of clinical (26·2 vs. 9·6%, p=NS) and mixed clinical/administrative (18·5 vs. 9·6%, p=NS) missed opportunities, although this failed to reach statistical significance. WHAT IS NEW AND CONCLUSION Evaluation of a triage tool for obstetric services demonstrated potential for prioritizing higher-risk patients for pharmacist review and addressing opportunities for clinical improvements.

Abstract
AIMS The metabolic syndrome (MetS) is a risk factor for cancer. However, it is not known if the MetS confers a greater cancer risk than the sum of its individual components, which components drive the association, or if the MetS predicts future cancer risk. MATERIALS AND METHODS We linked 20,648 participants from the Australian and New Zealand Diabetes and Cancer Collaboration with complete data on the MetS to national cancer registries and used Cox proportional hazards models to estimate associations of the MetS, the number of positive MetS components, and each of the five MetS components separately with the risk for overall, colorectal, prostate and breast cancer. Hazard ratios (HR) and 95% confidence intervals (95%CI) are reported. We assessed predictive ability of the MetS using Harrell's c-statistic. RESULTS The MetS was inversely associated with prostate cancer (HR 0.85; 95% CI 0.72-0.99). We found no evidence of an association between the MetS overall, colorectal and breast cancers. For those with five positive MetS components the HR was 1.12 (1.02-1.48) and 2.07 (1.26-3.39) for overall, and colorectal cancer, respectively, compared with those with zero positive MetS components. Greater waist circumference (WC) (1.38; 1.13-1.70) and elevated blood pressure (1.29; 1.01-1.64) were associated with colorectal cancer. Elevated WC and triglycerides were (inversely) associated with prostate cancer. MetS models were only poor to moderate discriminators for all cancer outcomes. CONCLUSIONS We show that the MetS is (inversely) associated with prostate cancer, but is not associated with overall, colorectal or breast cancer. Although, persons with five positive components of the MetS are at a 1.2 and 2.1 increased risk for overall and colorectal cancer, respectively, and these associations appear to be driven, largely, by elevated WC and BP. We also demonstrate that the MetS is only a moderate discriminator of cancer risk.

Abstract
This prospective 3-arm parallel-group randomized clinical trial investigated the effect of supplemental vibrational force on rate of orthodontic tooth alignment with fixed appliances. Eighty-one subjects (40 males, 41 females; mean age, 14.1 y) undergoing first premolar extraction-based fixed appliance treatment were randomly allocated to treatment supplemented with daily use (20 min) of a removable intraoral vibrational device (AcceleDent; OrthoAccel Technologies Inc.; n = 29), an identical nonfunctional (sham) device ( n = 25), or fixed appliances only ( n = 27). Mandibular study casts were taken at baseline (treatment start: placement of 0.014-in. nickel-titanium arch wire), initial alignment (0.018-in. nickel-titanium arch wire), and final alignment (0.019 x 0.025–in. stainless steel arch wire). Overall mean irregularity index in the mandibular arch at baseline was 8.5 ± 3.8 mm (95% CI, 7.6 to 9.3) with no significant difference between groups ( P = 0.73). For the total sample, mean irregularity index at initial alignment was 2.7 ± 2.8 mm (95% CI, 2.2 to 3.4) with no significant difference between groups ( P = 0.40). Mean time from baseline to initial alignment was 59 ± 25 d (95% CI, 54.5 to 65.6); from initial to final alignment, 150 ± 62.5 d (95% CI, 136 to 165); and baseline to final alignment, 209 ± 65 d (95% CI, 195 to 224). Kaplan-Meier analysis demonstrated that patterns of alignment were not significantly different among the 3 groups ( P = 0.66). Multivariate linear regression for initial and overall alignment rates using initial irregularity index as the covariate showed no significant differences among groups. The most important influence on both initial and overall rates of alignment was initial irregularity ( P = 0.1 × 10−4). This prospective randomized clinical trial found no evidence that supplemental vibrational force can significantly increase the rate of initial tooth movement or reduce the amount of time required to achieve final alignment when used in conjunction with a preadjusted edgewise fixed appliance ( ClinicalTrials.gov NCT02314975).

Consequences of varied soil hydraulic and meteorological complexity on unsaturated zone time lag estimates. JOURNAL OF CONTAMINANT HYDROLOGY 2014; 170:53-67. [PMID: 25444116 DOI: 10.1016/j.jconhyd.2014.10.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2014] [Revised: 09/29/2014] [Accepted: 10/01/2014] [Indexed: 06/04/2023]
Abstract
The true efficacy of a programme of agricultural mitigation measures within a catchment to improve water quality can be determined only after a certain hydrologic time lag period (subsequent to implementation) has elapsed. As the biophysical response to policy is not synchronous, accurate estimates of total time lag (unsaturated and saturated) become critical to manage the expectations of policy makers. The estimation of the vertical unsaturated zone component of time lag is vital as it indicates early trends (initial breakthrough), bulk (centre of mass) and total (Exit) travel times. Typically, estimation of time lag through the unsaturated zone is poor, due to the lack of site specific soil physical data, or by assuming saturated conditions. Numerical models (e.g. Hydrus 1D) enable estimates of time lag with varied levels of input data. The current study examines the consequences of varied soil hydraulic and meteorological complexity on unsaturated zone time lag estimates using simulated and actual soil profiles. Results indicated that: greater temporal resolution (from daily to hourly) of meteorological data was more critical as the saturated hydraulic conductivity of the soil decreased; high clay content soils failed to converge reflecting prevalence of lateral component as a contaminant pathway; elucidation of soil hydraulic properties was influenced by the complexity of soil physical data employed (textural menu, ROSETTA, full and partial soil water characteristic curves), which consequently affected time lag ranges; as the importance of the unsaturated zone increases with respect to total travel times the requirements for high complexity/resolution input data become greater. The methodology presented herein demonstrates that decisions made regarding input data and landscape position will have consequences for the estimated range of vertical travel times. Insufficiencies or inaccuracies regarding such input data can therefore mislead policy makers regarding the achievability of water quality targets.

Abstract
In the past decade, black walnut (Juglans nigra) trees throughout western North America have suffered from widespread branch dieback and canopy loss, causing substantial tree mortality (2,3). The fungus, Geosmithia morbida, vectored by the walnut twig beetle (WTB), Pityophthorus juglandis, has been associated with this devastating disease known as Thousand Cankers Disease (TCD) (2,3). In August of 2012, branch samples from TCD symptomatic black walnut trees (5 to 10 cm in diameter and 15 to 30 cm long) were collected on the North Carolina side of the Great Smoky Mountain National Park (GRSM) in Cataloochee Cove (35°37.023' N, 83°07.351' W) and near the Big Creek Campground (35°45.290' N, 83°06.473' W), in Haywood County. Five symptomatic trees near the Big Creek Campground and three from Cataloochee Cove displayed typical TCD signs including progressive crown thinning, branch flagging, and branch dieback; however, insect holes were not observed. Samples were double bagged in Ziploc plastic bags, sealed in a 19-liter plastic bucket, and transported to the University of Tennessee. Outer bark was removed from the samples and small, elliptical, necrotic cankers were observed. Wood chips (3 to 4 mm2) from cankers were excised and placed on 1/10 strength potato dextrose agar amended with 30 mg/liter streptomycin sulfate and 30 mg/liter chlortetracycline HCL and incubated on a 12-h dark/light cycle at 22°C for 5 to 7 days. Fungal isolates were tentatively identified as G. morbida by using culture morphology, and characteristics of conidiophores and conidia (2). The isolated fungus from the Cataloochee Cove location was grown in 1/10 strength potato dextrose broth at room temperature for 2 weeks. Isolates from Big Creek Campground were contaminated and were not analyzed further. Fungal colonies were tan to light yellow. Conidia were tan, subcylindrical, and catenulate. Conidiophores were multibranched, verticillate, and verrucose. To verify the morphological data, DNA was extracted from fungal mycelia using DNeasy Plant Mini Kit (Qiagen, Valencia, CA) according to the manufacturer's published protocol. Isolates from Cataloochee Cove were characterized using ITS1 and ITS4 universal primers (4). The putative G. morbida isolate (GenBank Accession No. KC461929) had ITS sequences that were 100% identical to the G. morbida type isolate CBS124663 (FN434082.1) (2). Additionally, fungal DNA from Cataloochee Cove was amplified using G. morbida-specific microsatellite loci (GS04, GS27, and GS36) (1). PCR products were analyzed with the QIAxcel Capillary Electrophoresis System (Qiagen) and were similar to those previously published (2). To date, all confirmed cases of TCD in the native range of black walnut have been in urban areas, along rural roadsides and/or fence rows. The report in North Carolina is the first finding of G. morbida, the causal agent of TCD, in a forest setting. References: (1) D. Hadziabdic et al. Conserv. Genet. Resources 4:287, 2012. (2) M.

Abstract
We present the simulation, implementation, and measurement of a multispectral metamaterial absorber (MSMMA) and show that we can realize a simple absorber structure that operates in the mid-IR and terahertz (THz) bands. By embedding an IR metamaterial absorber layer into a standard THz metamaterial absorber stack, a narrowband resonance is induced at a wavelength of 4.3 μm. This resonance is in addition to the THz metamaterial absorption resonance at 109 μm (2.75 THz). We demonstrate the inherent scalability and versatility of our MSMMA by describing a second device whereby the MM-induced IR absorption peak frequency is tuned by varying the IR absorber geometry. Such a MSMMA could be coupled with a suitable sensor and formed into a focal plane array, enabling multispectral imaging.

Abstract
Chemical amendment of dairy cattle slurry has been shown to effectively reduce incidental phosphorus (P) losses in runoff; however, the effects of amendments on incidental nitrogen (N) losses are not as well documented. This study examined P and N losses in runoff during three simulated rainfall events 2, 10 and 28 days after a single application of unamended/chemically amended dairy cattle slurry. Twenty-five hydraulically isolated plots, each measuring 0.9 m by 0.4 m and instrumented with runoff collection channels, were randomly assigned the following treatments: (i) grass-only, (ii) slurry-only (the study-control), (iii) slurry amended with industrial grade liquid alum comprising 8% Al₂O₃, (iv) slurry amended with industrial grade liquid poly-aluminum chloride (PAC) comprising 10% Al₂O₃, and (v) slurry amended with lime. During the first rainfall event, lime was ineffective but alum and PAC effectively reduced dissolved reactive P (DRP) (by 95 and 98%, respectively) and total P (TP) flow-weighted-mean-concentrations (by 82 and 93%, respectively) in runoff compared to the study-control. However, flow-weighted-mean-concentrations of ammonium-N (NH₄--N) in runoff were increased with alum- (81%) and lime-treated (11%) slurry compared to the study-control whereas PAC reduced the NH₄--N by 82%. Amendments were not observed to have a significant effect on NO₃--N losses during this study. Slurry amendments reduced P losses for the duration of the study, whereas the effect of amendments on N losses was not significant following the first event. Antecedent volumetric water content of the soil or slope of the plots did not appear to affect runoff volume. However, runoff volumes (and consequently loads of P and N) were observed to increase for the chemically amended plots compared to the control and soil-only plots. This work highlights the importance of considering both P and N losses when implementing a specific nutrient mitigation measure.

Abstract
The objective of the study was to evaluate the different headspace equilibration methods for the quantification of dissolved greenhouse gases in groundwater. Groundwater samples were collected from wells with contrasting hydrogeochemical properties and degassed using the headspace equilibration method. One hundred samples from each well were randomly selected, treatments were applied and headspace gases analysed by gas chromatography. Headspace equilibration treatments varied helium (He):water ratio, shaking time and standing time. Mean groundwater N(2)O, CO(2) and CH(4) concentrations were 0.024 mg N L(-1), 13.71 mg C L(-1) and 1.63 μg C L(-1), respectively. All treatments were found to significantly influence dissolved gas concentrations. Considerable differences in the optimal He:water ratio and standing time were observed between the three gases. For N(2)O, CO(2) and CH(4) the optimum operating points for He:water ratio was 4.4:1, 3:1 and 3.4:1; shaking time was 13, 12 and 13 min; and standing time was 63, 17 and 108 min, respectively. The headspace equilibration method needs to be harmonised to ensure comparability between studies. The experiment reveals that He:water ratio 3:1 and shaking time 13 min give better estimation of dissolved gases than any lower or higher ratios and shaking times. The standing time 63, 17 and 108 min should be applied for N(2)O, CO(2) and CH(4), respectively.

Abstract
We design, fabricate and characterise a narrowband Fabry-Pérot multispectral filter set for the visible range (400-750 nm) that is suitable for integration onto complementary-metal oxide-semiconductor image sensors. We reduce the fabrication steps by fixing the physical cavity length and altering the effective optical length instead. Using electron-beam lithography, a sub-wavelength hole array is patterned in a silicon nitride cavity layer, backfilled with poly(methyl methacrylate), and bounded by aluminium mirrors to create 23 filters with full-width half-maximums of 22-46 nm. Additionally, for colourmetric reproduction applications, using as few as 10 filters gives a colour difference (CIEDE2000) of 0.072, better than trichromatic filters.

Abstract
Dairy soiled water (DSW) is a dilute, low nutrient effluent produced on Irish dairy farms through the regular washing down of milking parlours and holding areas. In Ireland, there is no closed period for the land application of DSW except where heavy rain is forecast within 48 h. Chemical amendments have the potential to decrease phosphorus (P) and suspended sediment (SS) loss from DSW applied to land. This study examined the impact of three time intervals (12, 24 and 48 h) between DSW application and rainfall and five treatments (control, unamended DSW, and DSW amended with lime, alum or ferric chloride (FeCl(2))) on P and sediment losses from an intact grassland soil in runoff boxes. Rainfall was simulated at 10.5 ± 1 mm h(-1). Phosphorus concentrations (1-1.6 mg L(-1)) in runoff from DSW application, while not quantitative measures of P loss to surface waters in the field, indicated the importance of incidental P losses and that the current 48 h restriction in Ireland is prudent. Unamended DSW application increased P loss by, on average, 71%, largely due to an increase in particulate phosphorus (PP) loss. All three amendments were effective in decreasing P and SS losses in runoff and, apart from the SS results for lime, were significantly different (p<0.05) to the control at at least one time point. Lime (a 64% reduction in total phosphorus (TP) in comparison with DSW only) was less effective than alum or FeCl(2), likely due to the lower solubility of CaCO(3) in water. Chemical amendment showed potential to decrease P losses from land application of DSW, but the efficacy of such amendments would need to be assessed in field trials and a cost-benefit analysis conducted to further examine whether they could be practically implemented on farms.

Abstract
INTRODUCTION Since the late 1980s, British Columbia (BC) Canada has been undergoing a process of regionalization of health services which includes decentralization and the demand for self-sufficiency with respect to caring for people with mental health issues. In BC, regionalization has meant the continued downsizing of its one large provincial psychiatric hospital Riverview, which has resulted in relocating patients from this hospital to cities and towns throughout BC, and the establishment and/or renovation of psychiatric tertiary-care facilities to treat local community members who experience mental ill health. In the context of the relocation of psychiatric tertiary care, communities in northern BC face the specific challenge of having to provide these specialized services in remote settings, not only for people transferred from Riverview, but also for the increasing number of people 'aging-in-place' in a region that has the fastest growth of older adults in BC. Little is known about the capacity of these remote communities to manage change, develop broader models of care, and integrate people with psychogeriatric mental health issues with residents at existing facilities. METHODS This study employed a qualitative research design which involved field research in the rural community where people were transferred, and interviews and focus groups with key people involved in the transfer process. In the analysis of the data a gender-based lens was applied to clarify the differing needs and concerns of male and female patients and to attend to possible needs relating to culture and ethnicity. RESULTS The findings illustrate persistent 'hinterland-metropolis' and 'front-line versus administrative staff' tensions, with respect to resource distribution and top-down governance, and demonstrate the need for more transparent and comprehensive planning by health authorities with respect to instituting mental health reforms in a northern context, as well as improved communication between administrative and front-line staff. The research suggests that it is important to attend to the differing needs of women and men in the context of psychogeriatric care, as well as to other factors such as ethnicity and culture, in order to provide appropriate care. Finally, building community capacity to deal with the complex needs of patients is severely hampered not only by facility and regional health authority staff turnover, but also the stresses inherent to working in northern communities which include geographic, social and economic challenges. CONCLUSION Increased local engagement is a way to identify and address challenges related to relocating psychogeriatric care to northern and remote settings, and to enhance psychogeriatric care provision in similar locales. While provincial and regional level 'big picture' planning is a necessity, study participants highlighted the critical role of local perspective and expertise.

Abstract
California is the second largest sweet cherry producer in the United States with annual revenues up to $200 million. The South Australian cherry industry generates about 10% of Australia's overall production with approximately 1,500 metric tons of cherries produced yearly. In California, perennial canker diseases and subsequent branch dieback are responsible for extensive damage throughout sweet cherry orchards, reducing annual yields and tree longevity. Surveys of cherry orchards and isolation work were conducted in California to identify the main canker-causing agents. Calosphaeria pulchella was the main fungus isolated from cankers, followed by Eutypa lata and Leucostoma persoonii, respectively. Preliminary surveys in cherry orchards in South Australia documented C. pulchella and L. persoonii in cankers. The pathogenicity of C. pulchella in sweet cherry was confirmed following field inoculations of 2- to 3-year-old branches. C. pulchella was able to infect healthy wood and produce cankers with as much virulence as E. lata or L. persoonii. Spore trapping studies were conducted in two sweet cherry orchards in California to investigate the seasonal abundance of C. pulchella spores. Experiments showed that rain and sprinkler irrigation were important factors for aerial dissemination. Finally, this study illustrates the symptoms and signs of the new disease Calosphaeria canker.
