Differential Responses of Blood Essential Amino Acid Levels Following Ingestion of High-Quality Plant-Based Protein Blends Compared to Whey Protein-A Double-Blind Randomized, Cross-Over, Clinical Trial.

This study assessed the bio-equivalence of high-quality, plant-based protein blends versus Whey Protein Isolate (WPI) in healthy, resistance-trained men. The primary endpoint was incremental area under the curve (iAUC) of blood essential Amino Acids (eAAs) 4 hours after consumption of each product. Maximum concentration (Cmax) and time to maximum concentration (Tmax) of blood leucine were secondary outcomes. Subjects (n = 18) consumed three plant-based protein blends and WPI (control). An analysis of Variance model was used to assess for bio-equivalence of total sum of blood eAA concentrations. The total blood eAA iAUC ratios of the three blends were [90% CI]: #1: 0.66 [0.58-0.76]; #2: 0.71 [0.62-0.82]; #3: 0.60 [0.52-0.69], not completely within the pre-defined equivalence range [0.80-1.25], indicative of 30-40% lower iAUC versus WPI. Leucine Cmax of the three blends was not equivalent to WPI, #1: 0.70 [0.67-0.73]; #2: 0.72 [0.68-0.75]; #3: 0.65 [0.62-0.68], indicative of a 28-35% lower response. Leucine Tmax for two blends were similar to WPI (#1: 0.94 [0.73-1.18]; #2: 1.56 [1.28-1.92]; #3: 1.19 [0.95-1.48]). The plant-based protein blends were not bio-equivalent. However, blood leucine kinetic data across the blends approximately doubled from fasting concentrations, whereas blood Tmax data across two blends were similar to WPI. This suggests evidence of rapid hyperleucinemia, which correlates with a protein's anabolic potential.

Evaluation of Branched-Narrative Virtual Patients for Interprofessional Education of Psychiatry Residents.

OBJECTIVE: This pilot study evaluated the utility of branched-narrative virtual patients in an interprofessional education series for psychiatry residents. METHODS: Third-year psychiatry residents attended four interprofessional education advanced psychopharmacology sessions that involved completion of a branched-narrative virtual patient and a debriefing session with a psychiatric pharmacist. Pre- and post-assessments analyzed resident learning and were administered around each virtual patient. Simulation 4 served as a comprehensive review. The primary outcome was differences in pre- and post-assessment scores. Secondary outcomes included resident satisfaction with the virtual patient format and psychiatric pharmacist involvement. RESULTS: Post-test scores for simulations 1, 2, and 3 demonstrated significant improvement (p < 0.05) from pre-test scores. Scores for simulation 4 did not retain significance. Resident satisfaction with the branched-narrative virtual patient format and psychiatric pharmacist involvement was high throughout the series (100 %; n = 18). CONCLUSIONS: Although there are important methodological limitations to this study including a small sample size and absence of a comparator group, this pilot study supports the use of branched-narrative virtual patients in an interprofessional education series for advanced learners.

Isolated sinus tachycardia following reinitiation of risperidone in a patient with suspected autonomic hypersensitivity.

The second generation antipsychotic risperidone is generally considered to have low cardiac adverse events, with an increased risk of ventricular arrhythmias being reported only rarely in literature. We report here the case of a patient with a significant history of alcohol dependence, yet with no previous cardiac history, who had previously tolerated risperidone well, but had experienced isolated sinus tachycardia in the post detox period, following the reinitiation of risperidone therapy. The Naranjo Adverse Drug Reaction (ADR) probability scale rating for this being a medication adverse event (AE) was 4, thus indicating that this patient's AE was associated with risperidone therapy. This case report will contribute to the limited evidence of adverse cardiac events associated with risperidone therapy, with particular emphasis on the susceptibility of patients in a state of autonomic hypersensitivity.

Clinical effectiveness of baclofen for the treatment of alcohol dependence: a review.

Baclofen, an agonist at the B subunit of gaba-aminobutyric acid receptor, possesses pharmacologic properties that may confer utility for the treatment of alcohol dependence. Research suggests that not only can it be useful in promoting maintenance of alcohol abstinence but also it may play a key role in decreasing alcohol cravings and anxiety often associated with alcohol dependence. To assess the benefit of baclofen for alcohol dependence, a review of the literature was conducted to identify published data investigating this off-label treatment. Four randomized controlled trials to date have been published and were included in this review. Although primary outcomes differ between studies, patients randomized to baclofen experience higher rates of abstinence from alcohol than those taking placebo in two of the trials. Secondary analyses indicate that baclofen is safe in patients with alcohol dependence, including those with moderate to severe liver cirrhosis, and may provide beneficial anxiolytic effects. Despite some positive data, the largest available randomized controlled trial failed to find any differences between baclofen and placebo. In all studies, individuals with severe medical comorbidities, seizure disorders, and psychiatric disorders were excluded from trials, which may limit external validity. In summary, there may be beneficial effects from using baclofen for the treatment of alcohol dependence; however, limited conclusions can be drawn from the small number of studies currently available for review. Larger well-designed trials are needed to further define baclofen's role for the treatment of alcohol dependence.
