ReviewAdvances in the use of chloroquine and hydroxychloroquine for the treatment of COVID-19.
Coronavirus Disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is spreading worldwide. Antiviral therapy is the most important treatment for COVID-19. Among the drugs under investigation, anti-malarials, chloroquine (CQ) and hydroxychloroquine (HCQ), are being repurposed as treatment for COVID-19. ⋯ However, recent studies indicated that the use of CQ/HCQ, alone or in combination with a macrolide, did not show any favorable effect on patients with COVID-19. Adverse effects, including prolonged QT interval after taking CQ/HCQ, may develop in COVID-19 patients. Therefore, current data are not sufficient enough to support the use of CQ/HCQ as therapies for COVID-19 and increasing caution should be taken about the application of CQ/HCQ in COVID-19 before conclusive findings are obtained by well-designed, multi-center, randomized, controlled studies.

ReviewThe current state of acute treatment for migraine in adults in the United States.
Migraine is a common and disabling disorder with substantial personal, social, and economic burden that affects 37 million people in the United States. Risk factors for migraine include age, sex, and genetics. The goal of acute treatment of migraine attacks is to stop the pain and associated symptoms of the migraine attack and return the patient to normal function. ⋯ Unmet acute treatment needs still exist due to lack of efficacy, unwanted side effects, or contraindication to treatment. Effective treatment of migraine requires the clinician to assess the patient, make an accurate diagnosis, and then offer appropriate therapy based on the patient's medical history, comorbidities, and preferences, as well as published clinical evidence. The objective of this narrative review is to familiarize primary care clinicians with the variety of acute treatment options available in the United States today based on clinical trial findings, meta-analyses, evidence-based guidelines, and professional society consensus statements.

ReviewThe clinical significance of isolated diastolic hypertension.
The prevalence of isolated diastolic hypertension (IDH) has been increased in hypertensive subjects with the new 2017 ACC/AHA blood pressure treatment guidelines to 6.5% from 1.3% by the JNC-7 guidelines. However, its clinical significance as a cause of adverse cardiovascular (CV) events especially in older subjects has been debated by several investigators, who have demonstrated no adverse CV effects of untreated IDH, but not by others. It is also more common in the young subjects who are at low CV risk and quite rare in the older subjects, who are at increased CV risk. ⋯ In contrast, the prevalence of IDH is low in older subjects and is not associated with adverse CV events in the majority of cases. Thus, its further lowering should be avoided to prevent further decrease in normal SBP and prevent the onset of adverse CV events. However, the decision to treat IDH in older subjects should be individualized.

Redesigning Primary Care in an Academic Medical Center: Lessons, Challenges, and Opportunities.
To evaluate patient access, provider productivity, and patient satisfaction during a 24-month redesign process of an academic medical center, which requires balance between clinical and educational missions. ⋯ While this project was limited to one site, the inclusion of a set of well-planned metrics, and tracking of processes over time can provide insight for ongoing primary care redesign efforts at similar sites seeking to balance the academic mission with clinical productivity and high patient satisfaction.

The 'attended alone' and 'attended with' signs in the assessment of cognitive impairment: a revalidation.
Objectives: To examine the diagnostic utility of the 'attended alone' (AA) and 'attended with' (AW) signs for the diagnosis of major and minor neurocognitive disorder. Methods: Consecutive unselected new outpatient referrals (N = 1209) to a dedicated cognitive disorders clinic over a 5-year period (2015-2019 inclusive) were observed for the AA and AW signs. Criterion diagnoses were by usual clinic assessment using standard (DSM-5) diagnostic criteria. ⋯ Diagnostic utility of AW and AA was independent of patient gender. Conclusion: AW and AA are easily observed and categorized signs. AW has a high sensitivity for cognitive impairment while AA has a high positive predictive value for its absence.
