ObjectiveTo gain an understanding of what challenges pulse oximetry for paediatric pneumonia management poses, how it has changed service provision and what would improve this device for use across paediatric clinical settings in low-income countries.DesignFocus group discussions (FGDs), with purposive sampling and thematic analysis using a framework approach.SettingCommunity, front-line outpatient, and hospital outpatient and inpatient settings in Malawi and Bangladesh, which provide paediatric pneumonia care.ParticipantsHealthcare providers (HCPs) from Malawi and Bangladesh who had received training in pulse oximetry and had been using oximeters in routine paediatric care, including community healthcare workers, non-physician clinicians or medical assistants, and hospital-based nurses and doctors.ResultsWe conducted six FGDs, with 23 participants from Bangladesh and 26 from Malawi. We identified five emergent themes: trust, value, user-related experience, sustainability and design. HCPs discussed the confidence gained through the use of oximeters, resulting in improved trust from caregivers and valuing the device, although there were conflicts between the weight given to clinical judgement versus oximeter results. HCPs reported the ease of using oximeters, but identified movement and physically smaller children as measurement challenges. Challenges in sustainability related to battery durability and replacement parts, however many HCPs had used the same device longer than 4 years, demonstrating robustness within these settings. Desirable features included back-up power banks and integrated respiratory rate and thermometer capability.ConclusionsPulse oximetry was generally deemed valuable by HCPs for use as a spot-check device in a range of paediatric low-income clinical settings. Areas highlighted as challenges by HCPs, and therefore opportunities for redesign, included battery charging and durability, probe fit and sensitivity in paediatric populations.Trial registration numberNCT02941237.
Denosumab (Amgen, Thousand Oaks, California, USA) is a new bone antiresorptive agent used in patients with osteoporosis or metastatic cancer to the bones. As with the bisphosphonates that are used as antiresorptive medications, denosumab has been associated with osteonecrosis of the jaws (ONJ). Over the past two years there has been an increase in the literature describing ONJ in patients receiving agents such as denosumab. Due to promising study results that demonstrate the effectiveness of denosumab in avoiding skeletal complications related to osteoporosis and metastatic bone disease, more patients will receive denosumab in the future. It is reported that this has the potential to become a comparable challenge to bisphosphonate related osteonecrosis of the jaws (BRONJ) for clinicians. This article describes the management of two patients that developed ONJ while receiving denosumab, reviews the incidence of ONJ associated with denosumab, and contrasts the pharmacokinetics of denosumab and the bisphosphonates. The importance of avoiding interventional dental treatment until denosumab has been withdrawn for six months cannot be overstated.Keywords: Bisphosphonates, bisphosphonate related osteonecrosis of the jaws, denosumab, denosumab associated osteonecrosis of the jaws, necrosis of the jaws.Abbreviations and acronyms: BP = bisphosphonate; BRONJ = bisphosphonate related osteonecrosis of the jaws; DONJ = denosumab associated osteonecrosis of the jaws; FDA = US Food and Drug Administration; ONJ = osteonecrosis of the jaws; OPG = osteoprotegerin; PET = positron emission tomography; RANK = receptor activator of nuclear factor kappa; RANKL = receptor activator of nuclear factor kappa-B ligand.
In our survey of surgeons working in low-resource settings, a majority report poor surgical lighting as a major risk to patient safety and nearly one-third report delayed or cancelled operations due to poor lighting. Developing and distributing robust, affordable, high-quality surgical headlights could provide an ideal solution to this significant surgical safety issue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
