Rational and Experiential Decision-Making Preferences of Third-Year Student Pharmacists

Objective. To examine the rational (systematic and rule-based) and experiential (fast and intuitive) decision-making preferences of student pharmacists, and to compare these preferences to the preferences of other health professionals and student populations.Methods. The Rational-Experiential Inventory (REI-40), a validated psychometric tool, was administered electronically to 114 third-year (P3) student pharmacists. Student demographics and preadmission data were collected. The REI-40 results were compared with student demographics and admissions data to identify possible correlations between these factors.Results. Mean REI-40 rational scores were higher than experiential scores. Rational scores for younger students were significantly higher than students aged 30 years and older (p<0.05). No significant differences were found based on gender, race, or the presence of a prior degree. All correlations between REI-40 scores and incoming grade point average (GPA) and Pharmacy College Admission Test (PCAT) scores were weak.Conclusion. Student pharmacists favored rational decision making over experiential decision making, which was similar to results of studies done of other health professions.     

Changes in femur neck bone density in US adults between 1988–1994 and 2005–2008: demographic patterns and possible determinants

Summary  

This analysis compares femur neck bone mineral density (FNBMD) and bone determinants in adults between National Health and Nutrition Examination Survey (NHANES) III (1988–1994) and NHANES 2005–2008. FNBMD was higher in NHANES 2005–2008 than in NHANES III, but between-survey differences varied by age, sex, and race/ethnicity. The likelihood that FNBMD has improved appears strongest for older white women.     

Loss of Afferent Vestibular Input Produces Central Adaptation and Increased Gain of Vestibular Prosthetic Stimulation

Implanted vestibular neurostimulators are effective in driving slow phase eye movements in monkeys and humans. Furthermore, increases in slow phase velocity and electrically evoked compound action potential (vECAP) amplitudes occur with increasing current amplitude of electrical stimulation. In intact monkeys, protracted intermittent stimulation continues to produce robust behavioral responses and preserved vECAPs. In lesioned monkeys, shorter duration studies show preserved but with somewhat lower or higher velocity behavioral responses. It has been proposed that such changes are due to central adaptive changes in the electrically elicited vestibulo-ocular reflex (VOR). It is equally possible that these differences are due to changes in the vestibular periphery in response to activation of the vestibular efferent system. In order to investigate the site of adaptive change in response to electrical stimulation, we performed transtympanic gentamicin perfusions to induce rapid changes in vestibular input in monkeys with long-standing stably functioning vestibular neurostimulators, disambiguating the effects of implantation from the effects of ototoxic lesion. Gentamicin injection was effective in producing a large reduction in natural VOR only when it was performed in the non-implanted ear, suggesting that the implanted ear contributed little to the natural rotational response before injection. Injection of the implanted ear produced a reduction in the vECAP responses in that ear, suggesting that the intact hair cells in the non-functional ipsilateral ear were successfully lesioned by gentamicin, reducing the efficacy of stimulation in that ear. Despite this, injection of both ears produced central plastic changes that resulted in a dramatically increased slow phase velocity nystagmus elicited by electrical stimulation. These results suggest that loss of vestibular afferent activity, and a concurrent loss of electrically elicited vestibular input, produces an increase in the efficacy of a vestibular neurostimulator by eliciting centrally adapted behavioral responses without concurrent adaptive increase of galvanic afferent activation in the periphery.     

The Predictive Validity of Risk Assessment Approaches for Young Australian Offenders

Validation literature on the predictive ability of North American youth violence risk assessment inventories is developing across international settings. Yet no information exists on the utility of the Structured Assessment of Violence Risk in Youth (SAVRY) and the Psychopathy Checklist: Youth Version (PCL:YV),]and little research has been conducted on the Youth Level of Service/Case Management Inventory (YLS/CMI) across Australian young offender populations. The current study investigated the validity of the risk instruments on 213 young people in detention in Victoria, Australia. Findings indicated moderate to strong predictive accuracy for re-offence outcomes across the three inventories for the total sample and for males. The SAVRY was also able to identify the strength of protective factors for young female offenders. The inventories appear to be suitable prediction aides in the Australian youth justice context although further research is required to ascertain their applicability to Australian young female offenders.     

Echocardiographic diagnosis of permanent pacemaker lead malposition in the left ventricle: A case study

Inadvertent endocardial lead malposition is recognized as a rare incident which is usually underreported and if recognized during implantation can be easily corrected. This phenomenon is caused by the ventricular lead unintentionally crossing a pre-existing patent foremen ovale, septal defects (atrial or ventricular) or directly from the aorta via an accidental subclavian puncture resulting in the lead implanting into the left ventricle. While this is a rare occurrence we report, the incidental finding of pacemaker lead malposition during a routine follow-up transthoracic echocardiogram and the benefits of three-dimensional transesophageal echocardiography in this patient prior to lead extraction.     

The changing role of the pathologist in the management of Barrett's oesophagus

Pathological specimens from columnar‐lined oesophagus (CLO) comprise a considerable proportion of the workload of gastrointestinal pathologists in Western countries. There remain controversies concerning the diagnostic role of pathology. More recently, in the UK at least, the diagnosis has been regarded as primarily an endoscopic endeavour, with pathology being corroborative and only diagnostic when endoscopic features are equivocal or when there are additional features that make the endoscopic diagnosis unclear. There is also recognition that demonstration of intestinalisation or ‘goblet cells’ is not paramount, and should not be required for the diagnosis. There have been notable changes in the management of CLO neoplasia: pathologists are centrally involved in its management. Pathological assessment of endoscopic mucosal resection (EMR) specimens provides the most useful means of determining the management of early neoplasia and of determining indications for surgery. This represents an extraordinarily rapid change in management, in that, <10 years ago, laborious Seattle‐type biopsy protocols were recommended, and high grade dysplasia was an indication for resectional surgery. Now, individual patient management is paramount: multi‐professional meetings determine management after biopsy and EMR assessment. One significant change is that major resections are undertaken less often, in Western countries, for CLO neoplasia.     

Correlates of HPV Knowledge in the Era of HPV Vaccination: A Study of Unvaccinated Young Adult Women

Until recently, awareness of the sexually transmitted infection human papillomavirus—the virus that causes cervical cancer—was relatively low. The purpose of this study was to identify factors associated with human papillomavirus knowledge now that human papillomavirus vaccines have become widely available. Young adult women (n = 739; aged 18–26 years) attending Florida State University who had not yet initiated human papillomavirus vaccination completed a survey between March–August 2009. The survey assessed human papillomavirus awareness, human papillomavirus knowledge, demographics, socio-political variables, sexual history, and health history variables. Over 97% of participants were aware of human papillomavirus prior to study enrollment; however, knowledge of human papillomavirus was only moderate. A multivariate regression analysis examining factors related to human papillomavirus knowledge revealed five independent correlates: Latina ethnicity, premarital sex values, number of lifetime sexual partners, history of cervical dysplasia, and HIV testing. These variables accounted for 14% of the variance in human papillomavirus knowledge. Less knowledge was observed for Latinas and women opposed to premarital sex. Greater knowledge was observed for women who had been tested for HIV and women with more sexual partners or a history of cervical dysplasia. These findings can inform future human papillomavirus vaccination campaigns and may be particularly useful in developing interventions for individuals with the largest deficits in human papillomavirus knowledge.     

If Mothers Had Their Say: Research-Informed Intervention Design for Empowering Mothers to Establish Smoke-Free Homes

The Empowering Mothers to Establish Smoke-free Homes (EMESH) project developed in response to an interdisciplinary health team seeking effective interventions for reducing/eliminating the environmental tobacco smoke exposure of infants with compromised respiratory status. Two study phases that informed the EMESH intervention design are described. Phase I involved semi-structured interviews with 20 caretakers of infants diagnosed with Bronchopulmonary Dysplasia (BPD). In Phase II, 75 randomly selected medical records of infants with BPD were reviewed to explore the family demographics and staff behavior regarding environmental tobacco smoke (ETS) interventions. Interview results suggest that families are open to partnering with social workers and interdisciplinary team members in addressing infants’ ETS exposure, families’ unique circumstances indicate a need for tailored interventions, and the use of self-efficacy and decisional balance tools are feasible options. Results from the medical records review indicate that many families are economically vulnerable and reside in regions where smoking is common. There is a paucity of staff documentation regarding ETS conversations and interventions, indicating that these conversations may not take place. Together these results suggest a two-pronged approach in the next phases of EMESH: staff training in hosting and documenting ETS conversations and a tailored, parent-driven set of intervention options.
