Recent studies indicate that 123 I-iomazenil ( 123 I-IMZ) single-photon emission computed tomography (SPECT) can demonstrate neuronal viability. Although cognitive dysfunction has been recognized as an important issue in adult patients with moyamoya disease (MMD), no standard neuroradiological methods to define such conditions have been established. We examined the relationship between cognitive function and 123 I-IMZ SPECT before and after revascularization in patients with MMD. ⋯ Preoperative cognitive function was associated with 123 I-IMZ uptake in adult patients with MMD. After revascularization, cognitive function could be recovered in the viable areas of the brain, which is consistent with 123 I-IMZ SPECT findings.

Advancements in clinical science have shown the necessity for a paradigm shift away from a biomedical toward a biopsychosocial approach. Yet, the translation from clinical science into clinical practice is challenging. The aim of this study was to assess the short-term and mid-term changes in pain knowledge and attitudes and guideline-adherent recommendations of healthcare professionals (HCP) by means of an interdisciplinary training program (ITP) about chronic pain. ⋯ The knowledge and attitudes about pain scores improved at post-training (Δ = 9.04, 95% confidence interval 7.72-10.36) and at 6-month follow-up (Δ = 7.16, 95% confidence interval 5.73-8.59). After the training program, HCPs provided significantly more recommendations in accordance with clinical guidelines. Thus, an ITP can improve the biopsychosocial perspective of chronic pain management among HCPs in the short-term and mid-term.

While pharyngitis is a common primary care complaint, evidence reveals that this diagnosis is an area where antibiotic therapy is frequently misused. Appropriate diagnosis and management of pharyngitis is crucial to ensure antimicrobial stewardship and improve patient safety and outcomes. Pharyngitis etiologies include both infectious and noninfectious sources such as bacteria, viruses, fungal organisms, trauma, irritants, laryngopharyngeal reflux, and medications. Clinicians need to obtain a thorough history and careful physical examination, along with appropriate diagnostic testing when indicated, to ensure treatment plans are targeted toward the most likely pharyngitis etiology.

Voltage-gated sodium (Na v ) channels present untapped therapeutic value for better and safer pain medications. The Na v 1.8 channel isoform is of particular interest because of its location on peripheral pain fibers and demonstrated role in rodent preclinical pain and neurophysiological assays. To-date, no inhibitors of this channel have been approved as drugs for treating painful conditions in human, possibly because of challenges in developing a sufficiently selective drug-like molecule with necessary potency not only in human but also across preclinical species critical to the preclinical development path of drug discovery. ⋯ In this report, we have leveraged numerous physiological end points in nonhuman primates to evaluate the analgesic and pharmacodynamic activity of a novel, potent, and selective Na v 1.8 inhibitor compound, MSD199. These pharmacodynamic biomarkers provide important confirmation of the in vivo impact of Na v 1.8 inhibition on peripheral pain fibers in primates and have high translational potential to the clinical setting. These findings may thus greatly improve success of translational drug discovery efforts toward better and safer pain medications, as well as the understanding of primate biology of Na v 1.8 inhibition broadly.
