Hyperbaric oxygen therapy to treat lingering COVID-19 symptoms.

Background: SARs-Cov-2 infections can produce prolonged illness and significant disability. Patients recovering from COVID-19 can have persistent symptoms leading to long-term morbidity.

Methods: Six patients with long-lasting (> 30 days) COVID-19 symptoms were treated with hyperbaric oxygen (HBO2) therapy.

Clinical Inquiry: What is the most effective treatment for scabies?

Topical permethrin is the most effective treatment for classic scabies (strength of recommendation [SOR]: A, meta-analyses with consistent results). Topical lindane and crotamiton are inferior to permethrin but appear equivalent to each other and benzyl benzoate, sulfur, and natural synergized pyrethrins (SOR: B, limited randomized trials). Although not as effective as topical permethrin, oral ivermectin is an effective treatment compared with placebo (SOR: B, a single small randomized trial).

Clinical inquiries. What's the best way to monitor low-risk patients with a history of differentiated thyroid cancer?

Recombinant human thyrotropin (rhTSH)-stimulated serum thyroglobulin (Tg) level alone is sufficient to monitor for recurrent disease in low-risk patients with a history of differentiated thyroid cancer (DTC). Low-risk patients are defined as patients who have undergone total thyroidectomy and radioactive iodine (I(131)) remnant ablation therapy and show no clinical evidence of recurrent disease.

Analytic model for diffuse reflectivity of silicon nanowire mats.

Disordered silicon nanowires are diffuse optical reflectors, with reflectivity modified by the nanowire absorption. We present an analytical model which describes the reflectivity, absorption, and transmission of a nanowire mat, across a wide spectral range, and including substrate effects. The model provides the ability to predict the optical properties of other nanowire mat structures, including core/shell heterostructures.
