ABSTRACT

OBJECTIVE: Nonadherence to disease-modifying antirheumatic drugs (DMARDS) in rheumatoid arthritis (RA) and spondyloarthritis (SpA) results in increased disease activity and symptoms and poorer quality of life. We aimed to describe patients' attitudes and experiences of DMARDs in RA and SpA to inform strategies to improve medication adherence. METHODS: Databases (MEDLINE, Embase, PsycINFO, and CINAHL) were searched to January 2016. Thematic synthesis was used to analyze the findings. RESULTS: From 56 studies involving 1,383 adult patients (RA [n = 1,149], SpA [n = 191], not specified [n = 43]), we identified 6 themes (with subthemes): intensifying disease identity (severity of sudden pharmacotherapy, signifying deteriorating health, daunting lifelong therapy), distressing uncertainties and consequences (poisoning the body, doubting efficacy, conflicting and confusing advice, prognostic uncertainty with changing treatment regimens), powerful social influences (swayed by others' experiences, partnering with physicians, maintaining roles, confidence in comprehensive and ongoing care, valuing peer support), privilege and right of access to biologic agents (expensive medications must be better, right to receive a biologic agent, fearing dispossession), maintaining control (complete ownership of decision, taking extreme risks, minimizing lifestyle intrusion), and negotiating treatment expectations (miraculous recovery, mediocre benefit, reaching the end of the line). CONCLUSION: Patients perceive DMARDs as strong medications with alarming side effects that intensify their disease identity. Trust and confidence in medical care, positive experiences with DMARDS among other patients, and an expectation that medications will help maintain participation in life can motivate patients to use DMARDs. Creating a supportive environment for patients to voice their concerns may improve treatment satisfaction, adherence, and health outcomes.

ABSTRACT

Most humans harbor both CD177neg and CD177pos neutrophils but 1-10% of people are CD177null, placing them at risk for formation of anti-neutrophil antibodies that can cause transfusion-related acute lung injury and neonatal alloimmune neutropenia. By deep sequencing the CD177 locus, we catalogued CD177 single nucleotide variants and identified a novel stop codon in CD177null individuals arising from a single base substitution in exon 7. This is not a mutation in CD177 itself, rather the CD177null phenotype arises when exon 7 of CD177 is supplied entirely by the CD177 pseudogene (CD177P1), which appears to have resulted from allelic gene conversion. In CD177 expressing individuals the CD177 locus contains both CD177P1 and CD177 sequences. The proportion of CD177hi neutrophils in the blood is a heritable trait. Abundance of CD177hi neutrophils correlates with homozygosity for CD177 reference allele, while heterozygosity for ectopic CD177P1 gene conversion correlates with increased CD177neg neutrophils, in which both CD177P1 partially incorporated allele and paired intact CD177 allele are transcribed. Human neutrophil heterogeneity for CD177 expression arises by ectopic allelic conversion. Resolution of the genetic basis of CD177null phenotype identifies a method for screening for individuals at risk of CD177 isoimmunisation.

ABSTRACT

Sustainable implementation of new workforce redesign initiatives requires strategies that minimize barriers and optimize supports. Such strategies could be provided by a set of guiding principles. A broad understanding of the concerns of all the key stakeholder groups is required before effective strategies and initiatives are developed. Many new workforce redesign initiatives are not underpinned by prior planning, and this threatens their uptake and sustainability. This study reports on a cross-sectional qualitative study that sought the perspectives of representatives of key stakeholders in a new workforce redesign initiative (extended-scope-of-practice physiotherapy) in one Australian tertiary hospital. The key stakeholder groups were those that had been involved in some way in the development, management, training, funding, and/or delivery of the initiative. Data were collected using semistructured questions, answered individually by interview or in writing. Responses were themed collaboratively, using descriptive analysis. Key identified themes comprised: the importance of service marketing; proactively addressing barriers; using readily understood nomenclature; demonstrating service quality and safety, monitoring adverse events, measuring health and cost outcomes; legislative issues; registration; promoting viable career pathways; developing, accrediting, and delivering a curriculum supporting physiotherapists to work outside of the usual scope; and progression from "a good idea" to established service. Health care facilities planning to implement new workforce initiatives that extend scope of usual practice should consider these issues before instigating workforce/model of care changes.

ABSTRACT

BACKGROUND: There is generally a lengthy wait on outpatient orthopedic waiting lists in Australian public hospitals to consult a specialist. Patients then wait again for surgery, if required. Patients with higher need are rarely prioritized, and there is the potential for increased morbidity for those who wait. There is generally no option of alternative care whilst waiting. This paper compares historical orthopedic outpatient clinic data with the outcomes of a physiotherapy-led initiative in one large Australian tertiary hospital. METHODS: Two physiotherapists working within-scope conducted a telephone triage (October to December 2010) using a standard instrument for all new patients on the orthopedic waiting list. They were offered primary treatment options of retaining their appointment, being discharged, referral to a new model of assessment (multidisciplinary specialist clinic), or referral to physiotherapy. The outcomes were costs of the service, waiting time, and percentage of patients taking up management options. This was compared with a historical sample of new patients on the orthopedic waiting list (January to March 2009), whose treatment consumption was tracked longitudinally. RESULTS: The telephone triage resulted in 16.4% patients being discharged directly (compared with 0.1% comparison sample). For approximately AU$17.00 per patient, the telephone triage process released 21 booked appointments on the outpatient clinic waiting list. Moreover, approximately 26% patients were referred directly to physiotherapy, which was not a primary management option in the comparison sample. The waiting time for an appointment, for those patients who remained on the waiting list, was significantly shorter for the telephone triage sample than the comparison sample. There were significantly higher rates of failure to attend appointments, and significantly lower rates of discharge, in the comparison sample, than the telephone triage sample. CONCLUSION: A physiotherapist-led intervention offering alternative management options whilst patients waited for an orthopedic outpatient clinic consultation appears to be cost-effective, and patient-centered.

ABSTRACT

Calgranulins comprise three proteins, S100A8 (Calgranulin A), S100A9 (Calgranulin B) and S100A12 (Calgranulin C) that are predominantly expressed by neutrophils, monocytes and activated macrophages. These S100 calcium-binding proteins are important molecular mediators in a range of diseases, including inflammatory arthritis, atherosclerosis and microbial infections. Much of the literature has focused on the pro-inflammatory functions of calgranulins, and this has tended to underplay important regulatory, anti-oxidant and protective properties. S100A8 and S100A9 are particularly complex in their actions because they exert intracellular and extracellular functions, they form a heterocomplex, S100A8-A9 (calprotectin), and have actions that are independent of or dependent on heterocomplex formation. In some circumstances S100A9 appears to regulate, rather than synergize with the actions of S100A8 and vice versa. Moreover, these calgranulins also bind zinc and other divalent cations and are sensitive to post-translational oxidative modifications, properties that also affect some functions. It is important to note that S100A8 has potent anti-oxidant activity, which could be important in host protection. Furthermore, although the genes for S100A8 and S100A9 are induced by activation of the toll-like receptor/interleukin-1 pathway, their expression is enhanced by interleukin-10 and glucocorticoids, thus suggesting a regulatory role in inflammation. On the other hand, S100A12 appears to be predominantly pro-inflammatory, particularly by its ability to activate mast cells. Measurement of S100A12 levels may be a highly sensitive biomarker for inflammatory disease activity. This review summarizes the current understanding of the biology of calgranulins, with a focus on their pleiotropic roles in inflammatory arthritis.

ABSTRACT

A national review of learning disability services in Scotland, The Same As You? recommended that Health Boards should close all long stay beds by 2005 and reduce assessment and treatment places to specified levels. A psychiatry-led service planning study was carried out in 2007 to find out whether these recommendations had been met. The extent of delayed discharges was also investigated. All 15 Health Boards in Scotland responded and supplied the requested information. There were 388 adults with learning disabilities within inpatient services, 91 of whom were within forensic learning disability services. The age, gender, reasons for admission and length of stay are reported for this inpatient population. Recommendations are made for future recording of delayed discharges and the adequacy of the number of assessment and treatment inpatient places in Scotland is discussed.

ABSTRACT

Nontraumatic avascular necrosis (AVN) of bone is a well-reported complication of glucocorticoid therapy for immunologic and malignant disease. We present the case of a 13-year-old girl with no history of trauma who presented with a 5-day history of increasing pain in both knees after cord blood transplantation for acute lymphoblastic leukemia. Plain film and magnetic resonance imaging (MRI) were reported as normal. Bone scintigraphy revealed evidence of bilateral avascular necrosis in the distal femora. MRI subsequently became abnormal several weeks later. The case illustrates the natural history of AVN, in which changes that are detected by MRI can take several weeks to develop. The scintigraphic findings influenced early management of the condition.

ABSTRACT

UNLABELLED: Plantar fasciitis is a common cause of foot pain and may be disabling. Although localized injection is painful, anesthetics or corticosteroids can relieve symptoms well. Bone scintigraphy can confirm the diagnosis. We hypothesized that blood-pool abnormalities could provide prognostic information on the response to such injections. METHODS: We devised scintigraphic criteria that graded the blood-pool abnormalities as being localized to the plantar enthesis, being localized to half the length of the aponeurosis, or involving the whole aponeurosis. We evaluated 24 patients with an established diagnosis of plantar fasciitis, 8 of whom had bilateral disease, leading to a total of 32 feet injected. RESULTS: After injection, pain was relieved either completely or nearly completely in 20 feet. The other 12 feet had short-term or no improvement, with persistent pain and loss of function at 4-5 wk after injection. Of the 20 feet responding to injection, 14 had focal hyperemia on blood-pool images and 6 had minimal extension into the proximal third of the plantar soft tissues. No patient with diffuse hyperemia in the plantar fascia had a response (5/12 feet). On the delayed images of the 20 responders, mild inferior calcaneal uptake was seen in 8 feet, moderate uptake in 6, and severe uptake in 6. These groups did not significantly differ (P > 0.05). The blood-pool studies had good reproducibility, with a kappa-value of 0.64. CONCLUSION: Critical evaluation of plantar blood-pool images provides prognostic information on the response to localized injection into the enthesis. Reporting such studies is simple and reproducible.
