A Chronic Disease State Simulation in an Ambulatory Care Elective Course

Objective. To implement a chronic disease state simulation in an ambulatory care elective course and to assess the simulation’s impact on students’ perceptions of their empathy toward patients and of their counseling skills.Design. The chronic disease state simulation occurred over 2 weeks. Students alternated playing the role of patient and pharmacist. As patients, students adhered to medication regimens, lifestyle modifications, and blood glucose or blood pressure monitoring. As pharmacists, students conducted patient interviews, and provided education and counseling. Empathy and counseling skills were assessed through course surveys, written reflections, and SOAP notes.Assessment. Results from a cohort of 130 students indicated the simulation enhanced students’ perceptions of their abilities to empathize with and counsel patients with chronic diseases.Conclusion. The chronic disease state simulation provides a novel approach to develop skills needed for working with complex patient cases in ambulatory care settings.

Concurrent use of intranasal and orally inhaled fluticasone propionate does not affect hypothalamic-pituitary-adrenal-axis function.

Two double-blind, randomized, placebo-controlled, parallel group safety and efficacy studies included evaluation of the hypothalamic-pituitary-adrenal (HPA)-axis effects of concurrent treatment with intranasal and orally inhaled fluticasone propionate (FP). In the first study, patients with asthma who were > or =12 years of age were assigned randomly to receive twice-daily doses (either 88 or 220 microg) of orally inhaled FP delivered from a metered-dose inhaler (MDI). In the second study, patients were assigned randomly to receive either orally inhaled FP 250 microg or orally inhaled FP 250 microg/salmeterol 50 microg delivered via the Diskus device. In both studies, patients with rhinitis were allowed to continue the use of intranasal FP at their usual dosing. Treatment periods were 26 weeks and 12 weeks for the MDI and Diskus studies, respectively. HPA-axis effects were assessed using response to short cosyntropin stimulation testing. The number and percentage of patients with an abnormal cortisol response, defined as a morning plasma cortisol of <5 microg/dL, a poststimulation peak of <18 microg/dL, or a poststimulation rise of <7 microg/dL, were summarized in two subgroups: patients who used intranasal FP and those who did not. The concurrent administration of intranasal FP and orally inhaled FP via an MDI or Diskus or via Diskus with salmeterol was not associated with HPA-axis effects compared with orally inhaled FP alone. The results of these two studies suggest that concurrent use of intranasal FP with orally inhaled FP administered via MDI or Diskus for treatment of comorbid rhinitis and asthma does not increase the risk of HPA-axis abnormalities.     

Ischemia-driven target vessel revascularization after-primary percutaneous coronary intervention: patients at risk and their outcomes

Clinical and angiographic correlates of ischemia-driven target vessel revascularization (ITVR) in patients undergoing primary percutaneous coronary interventions (PCI) are currently less well known. Accordingly, we examined 2,981 patients enrolled in different Primary Angioplasty in Myocardial Infarction trials, who underwent primary PCI to evaluate risk factors and outcomes of individuals requiring subsequent ITVR. At 6 months, ITVR was required in 321 patients (11%). Compared to the cohort without ITVR, patients requiring ITVR were younger (P=0.036), females (P=0.018), and more likely to have systolic blood pressure >100 mmHg on presentation (P=0.022), family history of premature coronary artery disease (P=0.035), and postprocedure dissection (P=0.001). In contrast, Killip Class >I on presentation (P=0.05), left circumflex as infarct-related artery (P=0.022), and the use of ticlopidine (P=0.044) and stents (p=0.057) were less frequent among ITVR patients. Multivariate analysis identified younger age (for each 10-year decrease, odds ratio [OR], 1.18; 95% confidence interval [CI], 1.06-1.32), female gender (OR: 1.41, 95% CI: 1.05-1.89), and final dissection (OR: 1.69, 95% CI: 1.23-2.33) as independent risk factors for ITVR. In-hospital reinfarction (P < 0.001) was increased and at 6 months remained higher in ITVR patients; in-hospital and 6-month mortality did not differ between the two groups. Our study identifies the incidence, risk factors, and outcomes of patients requiring ITVR after primary PCI. Importantly, our data suggest that no increase in mortality occur, if ITVR is promptly performed to treat recurrent ischemia after primary PCI.     

Meta-analytic evidence for neuroimaging models of depression: State or trait?

Background

Major Depressive Disorder (MDD) is a leading cause of disease burden worldwide. With the rapid growth of neuroimaging research on relatively small samples, meta-analytic techniques are becoming increasingly important. Here, we aim to clarify the support in fMRI literature for three leading neurobiological models of MDD: limbic–cortical, cortico–striatal and the default mode network.

Methods

Searches of PubMed and Web of Knowledge, and manual searches, were undertaken in early 2011. Data from 34 case-control comparisons (n=1165) and 6 treatment studies (n=105) were analysed separately with two meta-analytic methods for imaging data: Activation Likelihood Estimation and Gaussian-Process Regression.

Results

There was broad support for limbic–cortical and cortico–striatal models in the case-control data. Evidence for the role of the default mode network was weaker. Treatment-sensitive regions were primarily in lateral frontal areas.

Limitations

In any meta-analysis, the increase in the statistical power of the inference comes with the risk of aggregating heterogeneous study pools. While we believe that this wide range of paradigms allows identification of key regions of dysfunction in MDD (regardless of task), we attempted to minimise such risks by employing GPR, which models such heterogeneity.

Conclusions

The focus of treatment effects in frontal areas indicates that dysregulation here may represent a biomarker of treatment response. Since the dysregulation in many subcortical regions in the case-control comparisons appeared insensitive to treatment, we propose that these act as trait vulnerability markers, or perhaps treatment insensitivity. Our findings allow these models of MDD to be applied to fMRI literature with some confidence.

Scientific Basis of Botanical Medicine as Alternative Remedies for Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune inflammatory disorder that causes permanent disability and mortality to approximately 1 to 100 people in the world. Patients with RA not only suffer from pain, stiffness, swelling, and loss of function in their joints, but also have a higher risk of cardiovascular disease and lymphoma. Typically prescribed medications, including pain-relieving drugs, nonsteroidal anti-inflammatory drugs (NSAID), and disease-modifying antirheumatic drugs, can help to relieve pain, reduce inflammation and slow the course of disease progression in RA patients. However, the general effectiveness of the drugs has been far from satisfactory. Other therapeutic modalities like TNF-alpha (TNF-α) inhibitors and interleukin-1 receptor antagonists targeting precise pathways within the immune system are expensive and may be associated with serious side effects. Recently, botanical medicines have become popular as alternative remedies as they are believed to be efficacious, safe and have over a thousand years experience in treating patients. In this review, we will summarize recent evidence for pharmacological effects of herbs including Black cohosh, Angelica sinensis, Licorice, Tripterygium wilfordii, Centella asiatica, and Urtica dioica. Scientific research has demonstrated that these herbs have strong anti-inflammatory and anti-arthritic effects. A wide range of phytochemicals including phenolic acids, phenylpropanoid ester, triterpene glycosides, phthalide, flavonoids, triterpenoid saponin, diterpene and triterpene have been isolated and demonstrated to be responsible for the biological effects of the herbs. Understanding the mechanisms of action of the herbs may provide new treatment opportunities for RA patients.
