RESUMEN
OBJECTIVE: We evaluated the efficacy and safety of trifarotene plus oral doxycycline in acne. METHOD(S): This was a randomized (2:1 ratio) 12-week, double-blind study of once-daily trifarotene cream 50microg/g plus enteric-coated doxycycline 120mg (T+D) versus trifarotene vehicle and doxycycline placebo (V+P). Patients were aged 12 years or older with severe facial acne (>=20 inflammatory lesions, 30 to 120 non-inflammatory lesions, and <=4 nodules). Efficacy outcomes included change from baseline in lesion counts and success (score of 0/1 with >=2 grade improvement) on investigator global assessment (IGA). Safety was assessed by adverse events and local tolerability. RESULT(S): The study enrolled 133 subjects in the T+D group and 69 subjects in the V+P group. The population was balanced, with an approximately even ratio of adolescent (12-17 years) and adult (>=18 years) subjects. The absolute change in lesion counts from baseline were: -69.1 T+D versus -48.1 V+P for total lesions, -29.4 T+D versus -19.5 V+P for inflammatory lesions, and -39.5 T+D versus -28.2 for non-inflammatory lesions (P<0.0001 for all). Success was achieved by 31.7 percent of subjects in the T+D group versus 15.8 percent in the V+P group (P=0.0107). The safety and tolerability profiles were comparable between the T+D and V+P arms. CONCLUSION(S): T+D was demonstrated to be safe and efficacious as a treatment option for patients with severe acne.Copyright © 2022 Matrix Medical Communications. All rights reserved.
RESUMEN
Ventilator sharing has been proposed as a method of increasing ventilator capacity during instances of critical shortage. We sought to assess the ability of a regulated, shared ventilator system, the multisplit ventilator system, to individualize support to multiple simulated patients using one ventilator. We employed simulated patients of varying size, compliance, minute ventilation requirement, and positive end-expiratory pressure (PEEP) requirement. Performance tests were performed to assess the ability of the system, versus control, to achieve individualized respiratory goals to clinically disparate patients sharing a single ventilator following ARDSNet guidelines (Acute Respiratory Distress Syndrome). Resilience tests measured the effects of simulated adverse events occurring to one patient on another patient sharing a single ventilator. The multisplit ventilator system met individual oxygenation and ventilation requirements for multiple simulated patients with a tolerance similar to that of a single ventilator. Abrupt endotracheal tube occlusion or extubation occurring to one patient resulted in modest, clinically tolerable changes in ventilation parameters for the remaining patients. The proof-of-concept ventilator system presented in this paper is a regulated, shared ventilator system capable of individualizing ventilatory support to clinically dissimilar simulated patients. It is resilient to common adverse events and represents a feasible option to ventilate multiple patients during a severe ventilator shortage. Copyright © 2022 by ASME.
