Published: October 2011

AbstractThis paper presents the outcome of an experimental design to investigate the impact of persuasive short messaging service (SMS) on students' self‐regulated learning strategies while attending an introductory information systems course over a 12‐week trimester. The participants were undergraduate students enrolled in INFO 101 at a tertiary institution in New Zealand. The instrument used in this study was the original motivated strategies for learning questionnaires (MSLQ) developed by Pintrich. MSLQ measures three general types of strategies: cognitive, meta‐cognitive and resource management. The findings of the research identified that several aspects of students' learning strategies had been improved for the experiment group while the Time and Study Environment Management dimension of MSLQ had been significantly lowered for the control group who received no SMS intervention. The study demonstrates a positive impact of persuasive SMS on students' learning and suggests that the intervention is able to improve students' self‐regulated learning effort compared to the control group. Moreover the study shows that students who received SMS intervention performed better than students who did not receive SMS intervention. Most importantly, the study shows that SMS intervention enables Māori and Pacific students, who historically have a lower performance than the main cohort, to perform better than the main cohort and to a significant level higher than those Māori and Pacific students who did not receive any SMS intervention. This study suggests that practitioners should consider the adoption of the persuasive SMS intervention by using the principles of persuasive technology for sending SMS messages especially for the high risk students.Practitioner NotesWhat is already known about this topic
Persuasive technology is the adoption of computing technology in an attempt to change attitudes and behaviour.

Practitioners should also target the persuasive SMS intervention to high risk students.
Capital Versus Performance Covenants in Debt Contracts
Authors: CHRISTENSEN HANS B. , NIKOLAEV VALERI V. 
Published: October 2011

ABSTRACTBuilding on contract theory, we argue that financial covenants control the conflicts of interest between lenders and borrowers via two different mechanisms. Capital covenants control agency problems by aligning debt holder–shareholder interests. Performance covenants serve as trip wires that limit agency problems via the transfer of control to lenders in states where the value of their claim is at risk. Companies trade off these mechanisms. Capital covenants impose costly restrictions on the capital structure, while performance covenants require contractible accounting information to be available. Consistent with these arguments, we find that the use of performance covenants relative to capital covenants is positively associated with (1) the financial constraints of the borrower, (2) the extent to which accounting information portrays credit risk, (3) the likelihood of contract renegotiation, and (4) the presence of contractual restrictions on managerial actions. Our findings suggest that accounting‐based covenants can improve contracting efficiency in two different ways.
Newly qualified nurses experiences in the intensive care unit
Authors: O’Kane Catherine E 
Published: October 2011

Aim: The aim of this research was to investigate newly qualified nurses (NQN) experiences of starting their career in the intensive care unit (ICU). The author also investigated the opinions of senior nurses from ICU in relation to NQN in ICU.Background: Although not a new concept, NQN in ICU has little substantive research to support recruitment. There is a current demand to investigate this topic, because of retention of staff and a shortage of qualified nurses.Method: This was a comparative, qualitative study using two forms of data collection. This study was conducted over two phases. Phase I, used semi‐structured interviews with eight NQN, with one participant for the pilot study. PHASE II used a focus group to interview seven senior nurses in ICU.Findings: NQN experienced anxiety about time management, accountability and socialization. Senior nurses felt NQN coped well with the demanding aspects of ICU but were aware that preceptors are under a lot of pressure. They were concerned about NQN lack of hospital knowledge. The competency‐based practice highlighted the importance of record keeping and its associated legal implications.Conclusion: NQN cope well with the complexity of ICU. Having student placements in this area seem to ease this transition and reduce some ‘reality shock’. They therefore seem better equipped to deal with the steep learning curve.
Effects of Prazosin, an α1‐Adrenergic Receptor Antagonist, on the Seeking and Intake of Alcohol and Sucrose in Alcohol‐Preferring (P) Rats
Authors: Verplaetse Terril L. , Rasmussen Dennis D. , Froehlich Janice C. , Czachowski Cristine L. 
Published: October 2011

Background:  Previous studies show that prazosin, an α1‐adrenergic receptor antagonist, decreases alcohol drinking in animal models of alcohol use and dependence [Rasmussen et al. (2009) Alcohol Clin Exp Res 3:264–272; Walker et al. (2008) Alcohol 42:91–97] and in alcohol‐dependent men [Simpson et al. (2009) Alcohol Clin Exp Res 33:255–263]. This study extended these findings by using a paradigm that allows for separate assessment of prazosin on motivation to seek versus consume alcohol or sucrose in selectively bred rats.Methods:  Alcohol‐preferring (P) rats were trained to complete an operant response that resulted in access to either 2% sucrose or 10% alcohol. A 4‐week Seeking Test Phase examined responding in single, weekly extinction sessions when no reinforcer could be obtained. A 4‐week Drinking Test Phase consisted of rats lever‐pressing to “pay” a specified amount up front to gain access to unlimited alcohol (or sucrose) for a 20‐minute period. On Seeking and Drinking test days, prazosin (0.0, 0.5, 1.0, and 1.5 mg/kg) was administered intraperitoneally 30 minutes prior to behavioral sessions.Results:  Rats were self‐administering an average of 0.9 (±0.09) g/kg alcohol on vehicle test day and had pharmacologically relevant blood ethanol concentrations. Prazosin significantly decreased alcohol seeking at all doses tested. The highest dose of prazosin also increased the latency to first response for alcohol and decreased alcohol intake. While sucrose‐seeking and intake were similarly affected by prazosin, the high dose of prazosin did not increase response latency.Conclusions:  These findings are consistent with and extend previous research and suggest that prazosin decreases motivation to initiate and engage in alcohol consumption. The specificity of prazosin in attenuating the initiation of alcohol‐ but not sucrose‐seeking suggests that this effect is not because of prazosin‐induced motor‐impairment or malaise. Together with previous findings, these data suggest that prazosin may be an effective pharmacotherapy, with specific application in people that drink excessively or have a genetic predisposition to alcohol abuse.
Alloimmunization to transfused platelets requires priming of CD4+ T cells in the splenic microenvironment in a murine model
Authors: Gilson Christopher R. , Zimring James C. 
Published: October 2011

BACKGROUND: Alloantibodies are a clinically significant sequelae of platelet (PLT) transfusion, potentially rendering patients refractory to ongoing PLT transfusion support. These antibodies are often IgG class switched, suggesting the involvement of CD4+ T‐cell help; however, PLT‐specific CD4+ T cells have not been visualized in vivo, and specifics of their stimulation are not completely understood.STUDY DESIGN AND METHODS: A murine model of alloimmunization to transfused PLTs was developed to allow in vivo assessment and characterization of CD4+ T cells specific for PLT major histocompatibility complex (MHC) alloantigen. PLTs were harvested from BALB/c mice, filter leukoreduced, and transfused into C57BL/6 recipients. PLT‐specific CD4+ T‐cell responses were visualized by using a T‐cell receptor transgenic mouse that detects peptide from donor MHC I presented on recipient MHC II. Antibody responses were determined by indirect immunofluorescence using BALB/c donor targets.RESULTS: C57BL/6 recipients of BALB/c leukoreduced PLT transfusions produced BALB/c antibodies, with proliferation of antigen‐specific CD4+ T cells seen in the spleen but not lymph nodes or liver. Depletion of recipient CD4+ cells or splenectomy independently abrogated the alloantibody response.CONCLUSION: We report a novel model to study antigen‐specific CD4+ T cells during alloimmunization to PLT transfusion. The presented data support a critical role for CD4+ T‐cell help in the humoral response to PLT transfusion and establish the spleen as a required microenvironment for effective CD4+ T‐cell priming against donor PLT–derived MHC I.

Published: October 2011

BACKGROUND: A large heterogeneity in current mobilization and collection practices is perceived. Moreover, recent evidence introduced novel issues into some specific topics. Optimization of the clinical practice, through the adoption of clinical practice guidelines, previously proved to reduce health care resource use.STUDY DESIGN AND METHODS: Two Italian scientific societies, Società Italiana Di Emaferesi e Manipolazione Cellulare (SIDEM) and Gruppo Italiano Trapianto Midollo Osseo (GITMO), perceived the need of hematologists and transfusionists to share a common paradigm in the setting of hematopoietic stem cell transplantation (SCT). The aim of the current position paper is to provide common definitions and criteria for mobilization and collection of peripheral blood stem cells both in autologous and in the allogeneic setting. Current international and national standards (i.e., International Society of Hematotherapy and Graft Engineering) and recommendations (i.e., European Group for Blood and Marrow Transplantation) were harmonized with the Panel recommendations.RESULTS: The Expert Panel consisted of nine members (five transfusionists and four hematologists with both clinical and scientific experience of SCT in both pediatric and adult setting) and one methodologist and first convened on April 19, 2010: they in turn agreed on the questions to be answered by the project. Available literature was reviewed by one expert and the methodologist and presented to the other members. Statements were then formulated. SIDEM and GITMO planned an informal meeting of the Panel every 2 years to discuss relevant updates and possible changes to the recommendations.CONCLUSION: The efforts of the expert panel members allowed to set up and share a common approach to the mobilization, enumeration, and collection issues in the field of both autologous and allogeneic peripheral blood SCT.

Social determinants of iron supplementation among women of reproductive age: a systematic review of qualitative data
Authors: Nagata Jason M. , Gatti Lisa R. , Barg Frances K. 
Published: October 2011

AbstractIron supplementation for women of reproductive age is a main part of an interdisciplinary strategy recommended for the control and prevention of iron deficiency and the treatment of mild‐to‐moderate iron‐deficiency anaemia. This systematic review reports the findings from a meta‐synthesis of qualitative data concerning the experiences and perceptions of iron supplementation among women of reproductive age and health service providers worldwide. Qualitative systematic review methods were used to conduct a search of published literature, define inclusion and exclusion criteria, appraise quality of studies and extract data on the use of iron supplementation among women of reproductive age. Coding, thematic analysis, reciprocal translation and line of argument synthesis were used to synthesize data. Twelve studies spanning 17 countries met inclusion criteria and were included in the analysis. Seven domains emerged from the review: cultural norms and societal values including explanatory models and medical pluralism; political and socio‐economic circumstances; education and communication; social organization and social relationships; health care access and supplement supply; food and nutrition availability; and adherence. In addition, 16 sub‐domains are highlighted. Connecting review findings to a conceptual framework of social determinants of health highlights salient issues that policy makers must consider when adapting global iron supplementation recommendations to the local context.

AbstractThis study utilized data from a prospective birth cohort study on 568 Indian children, to determine whether a longer duration of breastfeeding and later introduction of solid feeding were associated with a reduced higher body mass index (BMI) and less adiposity. Main outcomes were high BMI (>90th within‐cohort sex‐specific BMI percentile) and sum of skinfold thickness (triceps and subscapular) at age 5. Main exposures were breastfeeding (six categories from 1–4 to ≥21 months) and age of starting regular solid feeding (four categories from ≤3 to ≥6 months). Data on infant‐feeding practices, socio‐economic and maternal factors were collected by questionnaire. Birthweight, maternal and child anthropometry were measured. Multiple regression analysis that accounted for potential confounders demonstrated a small magnitude of effect for breastfeeding duration or introduction of solid feeds on the risk of high BMI but not for lower skinfold thickness. Breastfeeding duration was strongly negatively associated with weight gain (0–2 years) [adjusted β = –0.12 standard deviation, 95% confidence interval (CI): –0.19 to –0.05 per category change in breastfeeding duration, P = 0.001], and weight gain (0–2 years) was strongly associated with high BMI at 5 years (adjusted odds ratio = 3.8, 95% CI: 2.53–5.56, P < 0.001). In our sample, findings suggest that longer breastfeeding duration and later introduction of solids has a small reduction on later high BMI risk and a negligible effect on skinfold thickness. However, accounting for sampling variability, these findings cannot exclude the possibility of no effect at the population level.

Background Most stroke research has studied rehabilitation effectiveness and rehabilitation efficiency separately and not investigated the potential trade-offs between these two indices of rehabilitation. Aims To determine whether there is a trade-off between independent factors of rehabilitation effectiveness and rehabilitation efficiency. Methods Using a retrospective cohort study design, we studied all stroke patients ( n = 2810) from two sub-acute rehabilitation hospitals from 1996 to 2005, representing 87·5% of national bed-years during the same period. Results Independent predictors of poorer rehabilitation effectiveness and log rehabilitation efficiency were older age race-ethnicity caregiver availability ischemic stroke longer time to admission dementia admission Barthel Index score, and length of stay. Rehabilitation effectiveness was lower in females, and the gender differences were significantly lower in those aged ≥70 years (β −4·7 (95% confidence interval −7·4 to −2·0)). There were trade-offs between effectiveness and efficiency with respect to admission Barthel Index score and length of stay. An increase of 10 in admission Barthel Index score predicted an increase of 3·6% (95% confidence interval 3·2–4·0) in effectiveness but a decrease of 0·04 (95% confidence interval −0·05 to −0·02) in log efficiency (a reduction of efficiency by 1·0 per 30 days). An increase in log length of stay by 1 (length of stay of 2·7 days) predicted an increase of 8·0% (95% confidence interval 5·7–10·3) in effectiveness but a decrease of 0·82 (95% confidence interval −0·90 to −0·74) in log efficiency (equivalent to a reduction in efficiency by 2·3 per 30 days). For optimal rehabilitation effectiveness and rehabilitation efficiency, the admission Barthel Index score was 30–62 and length of stay was 37–41 days. Conclusions There are trade-offs between effectiveness and efficiency during inpatient sub-acute stroke rehabilitation with respect to admission functional status and length of stay.
Future directions for the Prostate Cancer Specialist Nurse in Australia
Authors: Sykes Julie 
Published: October 2011

Prostate cancer is the most commonly diagnosed cancer in Australian men. A cancer diagnosis causes physical, social and psychological morbidity. The role of the specialist nurse in chronic illness care is well recognized both nationally and internationally; however, the role of the Prostate Cancer Specialist Nurse is not as developed or formalized in Australian health care delivery. Prostate Cancer Foundation of Australia (PCFA) aims to bridge this gap and has developed a model to pilot a number of Prostate Cancer Specialist Nurses in various locations throughout both metropolitan and regional Australia.This paper reports on the findings of a project commissioned by PCFA to define a model for a national Prostate Cancer Specialist Nursing service. The service model was developed following an extensive consultation process at a national level. A framework for practice and professional development for the Prostate Cancer Specialist Nurse has been developed which utilizes both the Australian Nursing and Midwifery Council Registered Nurse Competency Frameworks and the National Cancer Nursing Education Project Professional Development Framework. The pilot program will involve PCFA working in partnership with host health regions by providing funding for the recruitment of the nurses on a 3‐year trial basis. The nurses will be employed directly by the host health regions and will be professionally supported by PCFA. The program will also be formally evaluated.
Assessing the role of non‐cotton refuges in delaying Helicoverpa armigera resistance to Bt cotton in West Africa

AbstractNon‐cotton host plants without Bacillus thuringiensis (Bt) toxins can provide refuges that delay resistance to Bt cotton in polyphagous insect pests. It has proven difficult, however, to determine the effective contribution of such refuges and their role in delaying resistance evolution. Here, we used biogeochemical markers to quantify movement of Helicoverpa armigera moths from non‐cotton hosts to cotton fields in three agricultural landscapes of the West African cotton belt (Cameroon) where Bt cotton was absent. We show that the contribution of non‐cotton hosts as a source of moths was spatially and temporally variable, but at least equivalent to a 7.5% sprayed refuge of non‐Bt cotton. Simulation models incorporating H. armigera biological parameters, however, indicate that planting non‐Bt cotton refuges may be needed to significantly delay resistance to cotton producing the toxins Cry1Ac and Cry2Ab. Specifically, when the concentration of one toxin (here Cry1Ac) declined seasonally, resistance to Bt cotton often occurred rapidly in simulations where refuges of non‐Bt cotton were rare and resistance to Cry2Ab was non‐recessive, because resistance was essentially driven by one toxin (here Cry2Ab). The use of biogeochemical markers to quantify insect movement can provide a valuable tool to evaluate the role of non‐cotton refuges in delaying the evolution of H. armigera resistance to Bt cotton.
A Randomized Clinical Trial Evaluating a Farm‐of‐Origin Autogenous Moraxella bovis Vaccine to Control Infectious Bovine Keratoconjunctivis (Pinkeye) in Beef Cattle

Published: October 2011

BackgroundA randomized, masked, 2‐arm parallel trial was conducted to assess the efficacy of a Moraxella bovis (M. bovis) autogenous vaccine to prevent naturally occurring infectious bovine keratoconjunctivis (IBK) in beef calves.HypothesisThe null hypothesis was that treatment group was not associated with either risk of IBK or last observed weight.AnimalsThe trial was conducted between May and November 2009 and 2010 on a university‐owned farm in Iowa. The vaccine contained 2 randomly selected M. bovis from IBK cases that occurred at the farm in 2008. Calves born between January and May 2009 and 2010 without visible corneal lesions were randomly allocated to receive vaccine (n = 191) or placebo (n = 178).MethodsTwo SC doses were administered 21–28 days apart. Allocation to treatment was concealed using bottles marked A or B. Staff observing the animals for IBK could not determine the treatment grouping. The herd met the “at‐risk” criteria (ie, >15% IBK in unvaccinated calves and M. bovis detection in IBK cases). Analysis was “per‐protocol”.ResultsThe risk of IBK was 58/185 (31%) in vaccinated calves and 66/173 (38%) in unvaccinated calves (adjusted risk ratio = 0.78; 95% CI, 0.49–1.24). Average weight before sale did not differ between the vaccinated calves (196.6 kg, SD ± 39.9) and unvaccinated calves (198.1 kg, SD ± 42.7) (P value = .19). No adverse effects were noted.Conclusion and Clinical ImportanceCombination of the study results with previous studies suggests that autogenous M. bovis vaccines often are ineffective in controlling naturally occurring IBK.
