ABSTRACTBackground  Sublingual buprenorphine is an effective maintenance treatment for opioid dependence, yet intravenous buprenorphine misuse occurs. A buprenorphine/naloxone formulation was developed to mitigate this misuse risk. This randomized, double‐blind, cross‐over study was conducted to assess the intravenous abuse potential of buprenorphine/naloxone compared with buprenorphine in buprenorphine‐maintained injection drug users (IDUs).Methods  Intravenous heroin users (n = 12) lived in the hospital for 8–9 weeks and were maintained on each of three different sublingual buprenorphine doses (2 mg, 8 mg, 24 mg). Under each maintenance dose, participants completed laboratory sessions during which the reinforcing and subjective effects of intravenous placebo, naloxone, heroin and low and high doses of buprenorphine and buprenorphine/naloxone were examined. Every participant received each test dose under the three buprenorphine maintenance dose conditions.Results  Intravenous buprenorphine/naloxone was self‐administered less frequently than buprenorphine or heroin (P < 0.0005). Participants were most likely to self‐administer drug intravenously when maintained on the lowest sublingual buprenorphine dose. Subjective ratings of ‘drug liking’ and ‘desire to take the drug again’ were lower for buprenorphine/naloxone than for buprenorphine or heroin (P = 0.0001). Participants reported that they would pay significantly less money for buprenorphine/naloxone than for buprenorphine or heroin (P < 0.05). Seven adverse events were reported; most were mild and transient.Conclusions  These data suggest that although the buprenorphine/naloxone combination has intravenous abuse potential, that potential is lower than it is for buprenorphine alone, particularly when participants received higher maintenance doses and lower buprenorphine/naloxone challenge doses. Buprenorphine/naloxone may be a reasonable option for managing the risk for buprenorphine misuse during opioid dependence treatment.

ABSTRACTAims  To describe the empirical construction and initial validation of the Cannabis Use Problems Identification Test (CUPIT), a brief self‐report screening instrument for detection of currently and potentially problematic cannabis use.Design  In a three‐phase prospective design an item pool of candidate questions was generated from a literature review and extensive expert consultation. The CUPIT internal structure, cross‐sectional and longitudinal psychometric properties were then systematically tested among heterogeneous past‐year users.Participants  Volunteer participants were 212 high‐risk adolescents (n = 138) and adults (n = 74) aged 13–61 years from multiple community settings.Measurements  The comprehensive assessment battery included several established measures of cannabis‐related pathology for CUPIT validation, with DSM‐IV/ICD‐10 diagnoses of cannabis use disorders as criterion standard.Findings  Sixteen items loading highly on two subscales derived from principal components analysis exhibited good to excellent test–retest (0.89–0.99) and internal consistency reliability (0.92, 0.83), and highly significant ability to discriminate diagnostic subgroups along the severity continuum (non‐problematic, risky, problematic use). Twelve months later, baseline CUPIT scores demonstrated highly significant longitudinal predictive utility for respondents’ follow‐up diagnostic group membership. Receiver operating characteristic (ROC) analysis identified a CUPIT score of 12 to be the optimal cut‐point for maximizing sensitivity for both currently diagnosable cannabis use disorder and those at risk of meeting diagnostic criteria in the following 12 months.Conclusions  The CUPIT is a brief cannabis screener that is reliable, valid and acceptable for use across diverse community settings and consumers of all ages. The CUPIT has clear potential to assist with achievement of public health goals to reduce cannabis‐related harms in the community.

ABSTRACTAim  To assess the effects of binge drinking on students' next‐day academic test‐taking performance.Design  A placebo‐controlled cross‐over design with randomly assigned order of conditions. Participants were randomized to either alcoholic beverage [mean = 0.12 g% breath alcohol concentration (BrAC)] or placebo on the first night and then received the other beverage a week later. The next day, participants were assessed on test‐taking, neurocognitive performance and mood state.Participants  A total of 196 college students (≥21 years) recruited from greater Boston.Setting  The trial was conducted at the General Clinical Research Center at the Boston Medical Center.Measurements  The Graduate Record Examinations© (GREs) and a quiz on a lecture presented the previous day measured test‐taking performance; the Neurobehavioral Evaluation System (NES3) and the Psychomotor Vigilance Test (PVT) measured neurocognitive performance; and the Profile of Mood States (POMS) measured mood.Findings  Test‐taking performance was not affected on the morning after alcohol administration, but mood state and attention/reaction‐time were affected.Conclusion  Drinking to a level of 0.12 g% BrAC does not affect next‐day test‐taking performance, but does affect some neurocognitive measures and mood state.

ABSTRACTAimsStudies have shown that the impairing effects of Δ‐9‐tetrahydrocannabinol (THC) are dose‐related. Cannabis intake increases the risk of traffic accidents. The purpose of this study was to see how different clinical tests and observations were related to blood THC concentrations and to determine whether the combined influence of THC and ethanol was different from either drug alone.DesignA retrospective cross‐sectional forensic database study.SettingDrivers apprehended by the police suspected of driving under the influence of alcohol other drugs.ParticipantsWe investigated 589 cases positive for THC only. In addition, 894 cases with THC and ethanol were included. A comparison was made with 3480 drivers with only ethanol in their blood and 79 drivers who tested negative.MeasurementsData were analytical results of blood samples and the 27 clinical tests and observations included in the Norwegian clinical test for impairment (CTI).FindingsNo relationship was found between blood THC concentration and most of the CTI tests. Blood THC concentration was, however, related to conjunctival injection, pupil dilation and reaction to light and to the overall risk of being judged impaired. When THC and ethanol were detected together the risk of being judged impaired was increased markedly.ConclusionsThis study demonstrates that cannabis impairs driving ability in a concentration‐related manner. The effect is smaller than for ethanol. The effect of ethanol and cannabis taken simultaneously is additive. Conjunctival injection, dilated pupils and slow pupil reaction are among the few signs to reveal THC influence.

A. Schiettecatte, C. Bourgain, C. Breucq, N. Buls, V. De Wilde and J. de Mey  Initial axillary staging of breast cancer using ultrasound‐guided fine needle aspiration: a liquid‐based cytology studyObjective:  To evaluate the preoperative detection of axillary metastasis combining ultrasound (US)‐guided fine needle aspiration cytology (FNAC) and liquid‐based cytology (Surepath®) to reduce sentinel node procedures.Methods:  In total, 148 patients with clinically negative lymph nodes and no preoperative therapy were included. All patients underwent preoperative ultrasound of the axilla with FNAC if suspicious lymph nodes were found. Complete axillary lymph node dissection was performed at primary surgery when FNAC was positive. All other patients underwent a sentinel node procedure.Results:  US‐guided FNAC of the axilla revealed metastasis in 34 (23.0%) of the 148 patients. These 34 patients were 53.1% of all patients (n = 64) with proven axillary lymph node involvement. In 66 patients (44.6%), both ultrasound and histopathology were negative. Overall sensitivity of US‐guided FNAC was 50.0%, specificity 100%, positive predictive value 100% and negative predictive value 70.2%. In T1 tumours, all patients referred for sentinel node procedure were node‐negative. The correlation between malignant FNAC and histopathology was 100%. US‐guided liquid‐based FNAC in patients with no clinically positive lymph nodes reduced the necessity for a sentinel node procedure by 23.0%.Conclusions:  We advocate that US‐guided fine needle aspiration (FNA) combined with liquid‐based cytology of axillary lymph nodes should be included in the preoperative staging of breast cancer.

AbstractThe effect of different combinations of time of sowing and depth and width of soil cultivation using a rotary slot‐seeding machine to introduce red clover (Trifolium pratense) was determined for some characteristics of newly established red clover plants in a lowland Dactylis glomerata‐dominated grassland in the Czech Republic. Sowing was carried out on four sowing dates in one growing season: 11 May; 21 June (after the first cut); 9 August (after the second cut); and 19 September. The experimental treatments consisted of all combinations of four depths (5, 10, 15 and 20 cm) and four widths (5, 10, 15 and 20 cm) of soil cultivation. Measurements were made of number of plants, weight and height of plants, weight and height of roots. Measurements at 2 months after sowing showed fewer seedlings for the 11 May sowing than for later sowing dates. The number of red clover plants increased as the row width was increased up to 15 cm, regardless of the depth of slot. Positive effects of slot width on weight and height of plants and weight and length of roots were recorded. A highly positive correlation was found between weight of plants and weight of roots. Width of row was the key factor for the successful establishment of seedlings into the existing sward by slot‐seeding. A row width of 10 cm and depth of slot of 5 cm was considered a satisfactory combination.

Journal of Advanced Nursing66(4), 911–922.AbstractTitle.  The Psychological Reward Satisfaction Scale: developing and psychometric testing two refined subscales for nurses. Aim.  This paper is a report of the development and psychometric testing of two refined subscales of the Psychological Reward Satisfaction Scale.Background.  Besides financial and material rewards, nurses also value psychological rewards: supportive and positively evaluated outcomes of the relationship an employee develops with the supervisor. Satisfaction with these rewards influences employees’ attitudes. Recently, the Psychological Reward Satisfaction Scale was developed to measure an employee’s satisfaction with psychological rewards. However, this instrument needs refinement before it can be used with a nursing sample.Method.  We conducted a pilot study to test the reliability of the refined subscales. Forty nurses completed an online survey twice, with a time interval of 2 weeks. Afterwards, we gathered survey data with a larger sample of 337 nurses to examine the two subscales and their influence on turnover intention and the turnover antecedents job satisfaction and organizational commitment (measured by validated scales) in more detail. Data collection took place in Belgium in 2006.Results.  The two refined subscales each contained four items. A series of hierarchical regression analyses suggested that satisfaction with psychological rewards from the head nurse has a statistically significant influence on nurses’ turnover intention, job satisfaction and affective commitment, whereas pay satisfaction has not. Satisfaction with psychological rewards from the physicians only explained nurses’ affective commitment.Conclusion.  When trying to motivate nurses through rewarding them, hospital managers should not only concentrate on financial rewards, but also pay attention to psychological rewards.

gallagher k., porock d. & edgley a. (2010) The concept of ‘nursing’ in the abortion services. Journal of Advanced Nursing66(4), 849–857.AbstractTitle.  The concept of ‘nursing’ in the abortion services. Aim.  This paper is a report of a study of the perceptions of nurses who work in abortion services.Background.  International debate surrounds abortion. In England and Wales the Abortion Act which was introduced in 1967 recently came under public review in relation to its legal limit of 24 weeks gestation. The review did not extend to those working within abortion services, and these nurses’ views remained unknown. Investigating the perceptions of nurses who work in abortion services adds a dimension to the debate from a professional perspective which has hitherto been absent.Methods.  Qualitative semi‐structured interviews were conducted in 2007 with nine nurses working in three different abortion clinics in the United Kingdom. NVivo was used to manage the interview data and thematic analysis identified patterns of nursing concepts and attitudes.Findings.  Two global themes of ‘Attitudes Towards’ and ‘Coping With’ abortion were identified. Six organizational themes detailed these: ‘society’, ‘nurses’ and ‘reasoning’ in ‘Attitudes Towards’ and ‘role’, ‘clients’ and ‘late gestation abortion’ in ‘Coping With’. Eleven basic themes further described the organizational themes. Kim’s theory of Human Living was used to clarify and provide a rationale for the nursing approach to care in this setting.Conclusion.  The ability of participants to care for their clients as individuals illustrates the nature of empowerment of the nurses to attain the goals of the client. Making this support explicit through defined roles for nurses would potentially enable nurses in abortion services to perform their role more effectively at all gestation times.

manias e. (2010) Medication communication: a concept analysis.Journal of Advanced Nursing66(4), 933–943.AbstractTitle. Medication communication: a concept analysis.Aim. This paper is a report of a concept analysis of medication communication with a particular focus on how it applies to nursing.Background. Medication communication is a vital component of patient safety, quality of care, and patient and family engagement. Nevertheless, this concept has been consistently taken‐for‐granted without adequate analysis, definition or clarification in the quality and patient safety literature.Data sources. A literature search was undertaken using bibliographic databases, internet search engines, and hand searches. Literature published in English between January 1988 and June 2009 was reviewed. Walker and Avant’s approach was used to guide the concept analysis.Discussion. Medication communication is a dynamic and complex process. Defining attributes consider who speaks, who is silent, what is said, what aspects of medication care are prioritized, the use of body language in conversations, and actual words used. Open communication occurs if there is cooperation among individuals in implementing plans of care. Antecedents involve environmental influences such as ward culture and geographical space, and sociocultural influences such as beliefs about the nature of interactions. Consequences involve patient and family engagement in communication, evidence of appropriate medication use, the frequency and type of medication‐related adverse events, and the presence of medication adherence. Empirical referents typically do not reflect specific aspects of medication communication.Conclusion. This concept analysis can be used by nurses to guide them in understanding the complexities surrounding medication communication, with the ultimate goal of improving patient safety, quality of care, and facilitating patient and family engagement.

Journal of Advanced Nursing66(4), 743–752.AbstractTitle.  The role of the public health nurse in a changing society. Aim.  This study is a report of a study to clarify the role of the public health nurse in one Irish community care area in the light of acknowledged problems in defining boundaries of the role.Background.  Demographic developments and planned reorientation towards primary care of the health service in Ireland have changed the workload of public health nurses, which is unique compared with other countries. However, there is a lack of clarity and consequent problems in defining the role of the Irish public health nurse.Method.  A descriptive qualitative study was conducted with 25 representatives of community nursing from one county in Ireland with a population of 209,077 and a complement of 65 full‐time equivalent public health nurses. Purposive sampling was used and 21 public health nurses, two registered general nurses, one assistant director and one school nurse participated. Tape‐recorded, individual semi‐structured interviews were conducted over a 15‐month period from 2002 to 2004. The constant comparative method was used for analysis.Findings.  Four themes emerged: ‘Jack of all trades: the role of the public health nurse defined and described’, ‘the essence of the role’, ‘challenges to the role of the public health nurse’ and ‘communication’. The first theme is discussed in this paper.Conclusion.  Public health nurses need to define and redesign their role so that they no longer think that they are the catch‐all service in the community. This will enable them to deal with the rapid demographic, sociological and cultural changes in the population, a change that has international resonance.

Journal of Advanced Nursing66(4), 828–838.AbstractTitle.  Self‐efficacy, self‐care behaviours and quality of life of kidney transplant recipients. Aim.  This paper is a report of an exploration of the effects of self‐efficacy and different dimensions of self‐management on quality of life among kidney transplant recipients.Background.  Self‐efficacy is an important factor influencing self‐management. Patients with higher self‐efficacy have better self‐management and experience better quality of life. Self‐efficacy influences the long‐term medication‐taking behaviour of kidney transplant recipients.Method.  A longitudinal, correlational design was used. Data were collected during 2005–2006 with 150 adult kidney transplant recipients on self‐efficacy, self‐management and quality of life using a self‐efficacy scale, self‐management scale and the Medical Outcomes Scale SF‐36 (Chinese), respectively. Relationships among variables were analysed by path analysis.Results.  Participants with higher self‐efficacy scored significantly higher on the problem‐solving (β = 0·51), patient–provider partnership (β = 0·44) and self‐care behaviour (β = 0·55) dimensions of self‐management. Self‐efficacy directly influenced self‐care behaviour and indirectly affected the mental health component of quality of life (total effect = 0·14). Problem‐solving and partnership did not statistically significantly affect quality of life. Neither self‐efficacy nor self‐management had any effect on the physical health component of quality of life.Conclusion.  Transplant care teams should incorporate strategies that enhance self‐efficacy, as proposed by social cognitive theory, into their care programmes for kidney transplant recipients. Interventions to maintain and improve patients’ self‐care behaviour should continue to be emphasized and facilitated. Support to enhance patients’ problem‐solving skills and the partnership of patients with health professionals is needed.

Journal of Advanced Nursing66(4), 839–848.AbstractTitle.  Effects of self‐efficacy, affectivity and collective efficacy on nursing performance of hospital nurses. Aim.  This paper is a report of a study conducted to examine the influence of self‐efficacy and affectivity (individual‐level variables) and collective efficacy (group‐level variable) on nursing performance among hospital nurses.Background.  Previous studies of nursing performance, which have focused on individual factor outcomes, have shown limitations. Due to the heavy focus on the analysis of single‐level performances, the influence of organizational contextual factors on nursing performance has rarely been studied. Hence, for a better understanding of nurses’ professional development and effective functioning in hospitals, there is a need to study the effects of organizational characteristics as well as individual characteristics on nursing performance.Method.  A descriptive‐correlational design was used with a convenience sample of 1996 nurses selected from 182 nursing units in 28 hospitals in six metropolitan cities and seven provinces in Korea. Data were collected in 2006 using self‐administered questionnaires, which were analysed with using descriptive statistics, Pearson correlation coefficients and multilevel analysis.Results.  Individual‐level variables, including job position, years of experience, employment status, self‐efficacy and positive affectivity were positively related to nursing performance. Collective efficacy and the number of in‐service meetings within units were statistically significant group‐level variables. Group‐level variables reduced the error variances in nursing performance.Conclusion.  Understanding the effects of group‐level variables on nursing performance improves performance management approaches in hospitals.
