Clinical effectiveness of flucloxacillin delivery using an elastomeric device for outpatient parenteral antimicrobial therapy.

There has been a surging interest in using elastomeric infusion devices to deliver outpatient parenteral antimicrobial therapy (OPAT), which is more cost-effective than standard antibiotic administration, which requires multiple daily home visits. This has been particularly important since the outbreak of the coronavirus pandemic, because reducing patient contact can also help to minimise transmission of COVID-19 to outpatients who are at a high risk of COVID-19-triggered complications. In this retrospective study, the clinical effectiveness of intravenous (IV) infusion of flucloxacillin using an elastomeric device was explored in a convenience sample of patients. Patients with three primary infective diagnoses-bloodstream infection, non-vertebral osteomyelitis and vertebral osteomyelitis-were included in the analyses. In non-vertebral osteomyelitis patients, Accufuser antibiotic infusion shortened the course of OPAT care relative to standard antibiotic administration (p<.05). In contrast, in vertebral osteomyelitis patients, it prolonged the course of OPAT care relative to standard administration (p<.05). In patients with bloodstream infections, no significant difference was found between the treatment modes (p=.93). Thus, the clinical effectiveness of Accufuser antibiotic infusion varies among patients with different infective diagnoses, and there seems to be a complex relationship between the method of antibiotic delivery and the patient's condition.

Water-associated attributes in the contemporary dentin bonding milieu.

OBJECTIVES: The water-associated attributes of resin-dentin interfaces created by contemporary adhesives are important determinants of bond integrity and stability. In the present work, these attributes were estimated from the perspectives of causality, to examine the behavior of the first and most-recently launched versions of universal adhesives when applied in either the etch-and-rinse mode or the self-etch mode. METHODS: The immediate cause of interfacial permeability and the time-dependent cause of water sorption were investigated in conjunction with the intermediate effect of interface degradation and the more long-term effect of loss of mechanical strength, before and after thermomechanical cycling. The results were compared with control etch-and-rinse and self-etch adhesives. RESULTS: Although the introduction of this new class of universal adhesives has brought forth significant changes to the dental adhesion arena, including more application options, reduced bonding armamentarium and increased user friendliness, the water-associated attributes that are critical for making resin-dentin bonds more durable to environmental challenges and less susceptible to degradation have remained unchanged at large, when compared with benchmarks established by former classes of adhesives. CONCLUSION: It appears that the current trend of adhesive development has brought forth significant changes but lacks the vigor that demarcates progress and technological sublimity. CLINICAL SIGNIFICANCE: The advent of the user friendly universal adhesives has brought forth significant changes to the dental adhesion arena. However, the elements that are critical for making resin-dentin bonds more durable to environmental challenges and less susceptible to degradation have remained unchanged at large.

'I'm Not Calling Him!': Disruptive Physician Behavior in the Acute Care Setting.

Results of a qualitative study of the experience of 15 acute care nurses with disruptive physician behavior and its impact on communication are reported. Findings will help educators and leaders prepare nurses by coaching and educating them on the importance of communication and patient advocacy.
