Evaluation and Treatment of Sexual Pain Disorders.

Pain that occurs during sexual activity is highly prevalent during a woman's lifetime, affecting ∼15% of women. The etiology of dyspareunia is multifactorial. Therefore, treatment must be individualized.

Workplace Violence in a Large Urban Emergency Department.

Importance: Workplace violence (WPV) against health care workers (HCWs) is common and likely underreported. Reliable data on the incidence of WPV and its impact on victims are lacking.

Objective: To prospectively define the frequency of WPV against HCWs in the emergency department (ED), examine whether HCW demographics are associated with increased risk, and explore the impact of these events on HCWs.

Evaluation of Low-Value Services Across Major Medicare Advantage Insurers and Traditional Medicare.

Importance: Compared with traditional Medicare (TM), Medicare Advantage (MA) insurers have greater financial incentives to reduce the delivery of low-value services (LVS); however, there is limited evidence at a national level on the prevalence of LVS utilization among MA vs TM beneficiaries and whether LVS utilization rates vary among the largest MA insurers.

Objective: To determine whether there are differences in the rates of LVS delivered to Medicare beneficiaries enrolled in MA vs TM, overall and by the 7 largest MA insurers.

Design, Setting, And Participants: This cross-sectional study included Medicare beneficiaries aged 65 years and older residing in the US in 2018 with complete demographic information.

Impact of modal gain and waveguide design on two-state lasing in quantum well-dot lasers.

We study the current-controlled lasing switching from the ground state (GS) to the excited state (ES) transition in broad-area (stripe width 100 µm) InGaAs/GaAs quantum well-dot (QWD) and quantum well (QW) lasers. In the lasers with one QWD layer and a 0.45 µm-thick GaAs waveguide, pure GS lasing takes place up to an injection current as high as 8 A (40 kA/cm).
