ABSTRACT

The high burden of kidney disease, global disparities in kidney care, and the poor outcomes of kidney failure place a growing burden on affected individuals and their families, caregivers, and the community at large. Health literacy is the degree to which individuals and organizations have, or equitably enable individuals to have, the ability to find, understand, and use information and services to make informed health-related decisions and actions for themselves and others. Rather than viewing health literacy as a patient deficit, improving health literacy lies primarily with health care providers communicating and educating effectively in codesigned partnership with those with kidney disease. For kidney policy makers, health literacy is a prerequisite for organizations to transition to a culture that places the person at the center of health care. The growing capability of and access to technology provides new opportunities to enhance education and awareness of kidney disease for all stakeholders. Advances in telecommunication, including social media platforms, can be leveraged to enhance persons' and providers' education. The World Kidney Day declares 2022 as the year of "Kidney Health for All" to promote global teamwork in advancing strategies in bridging the gap in kidney health education and literacy. Kidney organizations should work toward shifting the patient-deficit health literacy narrative to that of being the responsibility of health care providers and health policy makers. By engaging in and supporting kidney health-centered policy making, community health planning, and health literacy approaches for all, the kidney communities strive to prevent kidney diseases and enable living well with kidney disease.

ABSTRACT

BACKGROUND: The integration of general practitioners into specialist outpatient clinics is associated with improved access to care; however, little is understood about the organisation-level factors that affect successful implementation. We aimed to identify factors that were facilitators or barriers to the implementation of a General Practitioner with Special Interest (GPwSI) model of care across a range of specialties. METHODS: Semi-structured, in-depth interviews were conducted with 25 stakeholders at 13 GPwSI clinics in operation within a Queensland public health service. A deductive content analysis was conducted using the Consolidated Framework for Implementation Research (CFIR). RESULTS: Stakeholders generally supported the GPwSI model and saw advantages to patients and specialist medical practitioners in terms of waiting lists, workload, and improving clinician self-efficacy and knowledge. A number of factors were identified as being crucial to the success of the program, such as adequate support and planning for the implementation, appropriate funding and advocacy. CONCLUSIONS: Our evaluation indicates that a GPwSI model can be a beneficial resource for improving care to patients and reducing wait lists, dependent upon adequate planning, training, and support.

ABSTRACT

Nurses and midwives of Australia now is the time for change! As powerfully placed, Indigenous and non-Indigenous nursing and midwifery professionals, together we can ensure an effective and robust Indigenous curriculum in our nursing and midwifery schools of education. Today, Australia finds itself in a shifting tide of social change, where the voices for better and safer health care ring out loud. Voices for justice, equity and equality reverberate across our cities, our streets, homes, and institutions of learning. It is a call for new songlines of reform. The need to embed meaningful Indigenous health curricula is stronger now than it ever was for Australian nursing and midwifery. It is essential that nursing and midwifery leadership continue to build an authentic collaborative environment for Indigenous curriculum development. Bipartisan alliance is imperative for all academic staff to be confident in their teaching and learning experiences with Indigenous health syllabus. This paper is a call out. Now is the time for Indigenous and non-Indigenous nurses and midwives to make a stand together, for justice and equity in our teaching, learning, and practice. Together we will dismantle systems, policy, and practices in health that oppress. The Black Lives Matter movement provides us with a 'now window' of accepted dialogue to build a better, culturally safe Australian nursing and midwifery workforce, ensuring that Black Lives Matter in all aspects of health care.

ABSTRACT

Bait collection is a multibillion dollar worldwide activity that is often managed ineffectively. For managers to understand the impacts on protected inter-tidal mudflats and waders at appropriate spatial scales macrofaunal surveys combined with video recordings of birds and bait collectors were undertaken at two UK sites. Dug sediment constituted approximately 8% of the surveyed area at both sites and is less muddy (lower organic content) than undug sediment. This may have significant implications for turbidity. Differences in the macrofaunal community between dug and undug areas if the same shore height is compared as well as changes in the dispersion of the community occurred at one site. Collection also induces a 'temporary loss of habitat' for some birds as bait collector numbers negatively correlate with wader and gull abundance. Bait collection changes the coherence and ecological structure of inter-tidal mudflats as well as directly affecting wading birds. However, as ß diversity increased we suggest that management at appropriate hectare/site scales could maximise biodiversity/function whilst still supporting collection.

ABSTRACT

INTRODUCTION: The shortage of nurses willing to work in rural Australian healthcare settings continues to worsen. Australian rural areas have a lower retention rate of nurses than metropolitan counterparts, with more remote communities experiencing an even higher turnover of nursing staff. When retention rates are lower, patient outcomes are known to be poorer. This article reports a study that sought to explore the reasons why registered nurses resign from rural hospitals in the state of New South Wales, Australia. METHODS: Using grounded theory methods, this study explored the reasons why registered nurses resigned from New South Wales rural hospitals. Data were collected from 12 participants using semi-structured interviews; each participant was a registered nurse who had resigned from a rural hospital. Nurses who had resigned due to retirement, relocation or maternity leave were excluded. Interviews were transcribed verbatim and imported into NVivo software. The constant comparative method of data collection and analysis was followed until a core category emerged. RESULTS: Nurses resigned from rural hospitals when their personal value of how nursing should occur conflicted with the hospital's organisational values driving the practice of nursing. These conflicting values led to a change in the degree of value alignment between the nurse and hospital. The degree of value alignment occurred in three dynamic stages that nurses moved through prior to resigning. The first stage, sharing values, was a time when a nurse and a hospital shared similar values. The second stage was conceding values where, due to perceived changes in a hospital's values, a nurse felt that patient care became compromised and this led to a divergence of values. The final stage was resigning, a stage where a nurse 'gave up' as they felt that their professional integrity was severely compromised. The findings revealed that when a nurse and organisational values were not aligned, conflict was created for a nurse about how they could perform nursing that aligned with their internalised professional values and integrity. Resignation occurred when nurses were unable to realign their personal values to changed organisational values - the organisational values changed due to rural area health service restructures, centralisation of budgets and resources, cumbersome hierarchies and management structures that inhibited communication and decision making, out-dated and ineffective operating systems, insufficient and inexperienced staff, bullying, and a lack of connectedness and shared vision. CONCLUSIONS: To fully comprehend rural nurse resignations, this study identified three stages that nurses move through prior to resignation. Effective retention strategies for the nursing workforce should address contributors to a decrease in value alignment and work towards encouraging the coalescence of nurses' and hospitals' values. It is imperative that strategies enable nurses to provide high quality patient care and promote a sense of connectedness and a shared vision between nurse and hospital. Senior managers need to have clear ways to articulate and imbue organisational values and be explicit in how these values accommodate nurses' values. Ward-level nurse managers have a significant responsibility to ensure that a hospital's values (both explicit and implicit) are incorporated into ward culture.

ABSTRACT

OBJECTIVE: To determine the clinical impact of muscle involvement in a large systemic sclerosis (SSc) cohort. METHOD: Using the Canadian Scleroderma Research Group (CSRG) database, SSc patients with either elevated creatine kinase (CK) or a prior history of myositis/myopathy were identified. Regression and Kaplan-Meier analyses were performed to determine characteristics associated with muscle involvement in SSc and survival outcome. RESULTS: In 1145 patients with SSc, 5.6% had an elevated CK. This subset was more likely to be male (24.5% in elevated CK vs. 12.6% in normal CK, p < 0.013), younger (52 vs. 56 years, p < 0.045), have diffuse cutaneous SSc (dcSSc; 40.4% vs. 37.9%, p < 0.002), tendon friction rubs (30.0% vs. 13.4%, p < 0.001), and forced vital capacity (FVC) < 70% (23.9% vs. 13.1%, p < 0.039), be ribonucleoprotein (RNP) antibody positive (12.0% vs. 5.0%, p < 0.032), topoisomerase1 (topo1)-antibody positive (26.0% vs. 14.4%, p < 0.026), have a higher modified Rodnan skin score (MRSS; 16.14 vs. 9.81, p < 0.001), and a higher Health Assessment Questionnaire (HAQ) score (0.98 vs. 0.79, p < 0.011). Survival was reduced for patients with elevated CK (p < 0.025). Nearly 10% of patients in the CSRG cohort had a prior history of myositis/myopathy. This subset also had findings similar to those with elevated CK and increased mortality (p < 0.003). CONCLUSIONS: Muscle involvement in SSc has a poor prognosis impacting survival, especially in men with early dcSSc with topo1 and RNP autoantibodies and interstitial lung disease (ILD).

ABSTRACT

OBJECTIVE: To investigate the relationship between function and disease activity in early inflammatory arthritis (EIA). METHODS: Canadian Early Arthritis Cohort (CATCH) (n=1143) is a multi-site EIA cohort. Correlations between the Health Assessment Questionnaire Disability Index (HAQ) and DAS28 were done at every 3 months for the first year and then at 18 and 24 months. We also investigated the relationship between HAQ and DAS28 by age (<65 versus ≥65) and RF (positive vs negative). RESULTS: Mean HAQ and DAS28 scores were highest at the initial visit with HAQ decreasing over 24 months from a baseline of 0.94 to 0.40 and DAS28 scores decreasing from 4.54 to 2.29. All correlations between HAQ and DAS28 were significant at all time points (p<0.01). The correlations between HAQ and DAS28 were variable over time. The strongest correlation between HAQ and DAS28 occurred at initial visit (most DMARD naive) (n=1,143) and 18 months (r=0.57, n=321) and 24 months (r=0.59, n=214). The baseline correlation between HAQ and DAS28 was significantly different than correlations obtained at 3, 6, and 12 months (p=0.02, 0.01, and 0.01, respectively). Age did not change the association between HAQ and DAS28 {<65 years old (r=0.50, n=868) versus ≥65 (r=0.48, n=254), p=0.49}. The correlation between HAQ and DAS28 was stronger with RF+ patients (r=0.63, n=636) vs RF negative (r=0.47, n=477), p=0.0043. CONCLUSION: Over 2 years in EIA, HAQ and DAS both improved; correlations at time points were different over 2 years and RF status affected the correlations.

ABSTRACT

OBJECTIVE: It is known that age at disease onset has an impact on the clinical course and outcome of systemic lupus erythematosus (SLE); however, the precise differences in the prevalence of SLE manifestations are debated. Our objective was to conduct a systematic literature review and meta-analysis of all studies that directly compare childhood-onset lupus with adult-onset lupus to determine which clinical manifestations vary with age at disease onset. METHODS: A comprehensive literature search of the MEDLINE/PubMed,EMBASE, CINAHL, and SCOPUS databases was conducted to identify relevant articles. Study quality was assessed using the STROBE checklist. Study sample characteristics and clinical manifestation event rates were extracted from each study. Pooled odds ratios (ORs) were calculated using the random effects method, and between-study heterogeneity was quantified using the I (2) statistic. RESULTS: Of the 484 studies identified by the search strategy, 16 were included in this review. The total number of patients was 5993 adults and 905 children with SLE. Study quality was on average 16/32, ranging from 8 to 29. Several statistically significant differences were found: malar rash, ulcers/mucocutaneous involvement, renal involvement, proteinuria, urinary cellular casts, seizures, thrombocytopenia, hemolytic anemia, fever, and lymphadenopathy were more common in childhood-onset SLE with ORs ranging from 1.3 to 3.7; however, Raynaud's, pleuritis, and sicca were more common in adult-onset SLE (twice as common). CONCLUSIONS: The results of this meta-analysis suggest that some clinical manifestations of lupus are different in childhood-onset SLE and adult-onset SLE.

ABSTRACT

Secretory immunoglobulin A (SIgA) is the most prevalent antibody in the human body and a first line of defense in mucosal immunity. We located secretory component (SC) relative to dimeric IgA1 (dIgA1) within the SIgA1 structure using the constrained modeling of solution scattering and analytical ultracentrifugation data. The extended solution structure of dIgA1 is largely preserved within SIgA1. From conformational searches of SC locations, the best-fit SC models within SIgA1 show that SC is extended along the outermost convex edge of the Fc dimer in dIgA1. The topology of our SIgA1 structure reveals that it is able to bind to one FcalphaRI receptor molecule. SC binding to the Fc dimer confers protection to SIgA1 by the masking of proteolytically susceptible surface sites from bacterial proteases in the harsh environment of the mucosa. The models support a "zipper-like" unfolding of SC upon dIgA1 in the formation and transportation of SIgA1 into the mucosa.

ABSTRACT

INTRODUCTION: Like the fictional 'Accidental Tourist', an author who does not plan to write about travel, the accidental mentor is an experienced rural nurse who does not plan to be a mentor, and yet assumes that role with new or novice rural nurses as a result of them encountering a critical incident. Accidental mentoring is a short-term relationship that provides support for the new or novice nurse in managing the incident, while maintaining their level of confidence. This article describes the findings from a constructivist grounded theory study that examined Australian rural nurses' experiences of mentoring, including evidence for a new concept of mentoring - accidental mentoring. METHODS: Constructivist grounded theory is a research methodology that focuses on issues of importance for participants around an area of common interest - in this case Australian rural nurse mentoring. In this study, seven participants were interviewed, generating nine transcripts. These were analysed using a process of concurrent data generation and analysis. In addition, the literature regarding rural nurse workforce and mentoring was incorporated as a source of data, using collective frame analysis. RESULTS: Rural nurses live their work, which predisposes them to developing supportive relationships with new or novice rural nurses. Supportive relationships range from preceptoring, to accidental mentoring, mentoring and deep friendship, depending on the level of trust and engagement that is established between the partners and the amount of time they spend together. Accidental mentoring is a short-term relationship that is prompted by experienced rural nurses observing a new or novice rural nurse experiencing a critical incident. CONCLUSIONS: Findings are presented that illustrate a new concept of accidental mentoring not present in the current literature around nurse mentoring. A series of recommendations are included that suggest strategies for improved rural nurse retention as an outcome of recognising and developing such supportive relationships in the workplace. Strategies include: performance review and development processes that account for all forms of supportive relationships conducted in the workplace; recognising the importance of developing supportive relationships and allocating time for these; and continuing professional development designed to meet local needs for developing a culture of support in the workplace.

ABSTRACT

Oligonucleotide array based analysis was conducted to examine the temporal pattern of gene expression across the various stages of lung development to identify regulatory pathways at key developmental time points. Whole embryo total RNA or embryonic lung total RNA was harvested from A/J mice at seven developmental stages. To investigate changes in gene expression during lung development, four samples from each stage were examined using Affymetrix U74Av2 murine oligonucleotide microarrays. From the over 12,000 genes and ESTs represented on the array, 1346 genes and ESTs were identified as having a significant change in expression between at least one time point and the others (p<0.001, Kruskal-Wallis test). Within this group of approximately 1300 genes, four patterns of expression were seen: (1) upregulation during the embryonic period of development (up-down); (2) upregulation during the postnatal period of lung development (down-up) and (3) fluctuating expression, up initially, down for one or more time points, and then up again (up-down-up); and (4) vice versa (down-up-down). Expression patterns of genes previously reported to be involved in pulmonary development were also examined. Using the pathway visualisation tool, GenMapp, at least three regulatory pathways were found to contain clusters of differentially expressed genes: Wnt signalling, cell cycle, and apoptosis. Furthermore, we have shown that many of the genes involved in lung development are either known oncogenes or tumour suppressor genes altered in lung cancer, such as Cyr61, Rassf1a, and Dutt1/Robo1, or putative lung cancer genes. In addition, the genes identified pertinent to early development may also serve as candidate susceptibility genes for various inherited lung cancer disorders as well as for various heritable disorders of lung development. These results will contribute to our understanding of novel aspects of the regulatory machinery for embryonic lung development and of the genes involved in lung tumorigenesis.

ABSTRACT

Few studies have measured brain protein synthesis in vivo using reliable methods that consider the precursor pool, and there is a paucity of data on the regional sensitivity of this organ to nutritional or toxic substances. We hypothesized that different areas of the brain will exhibit variations in protein synthesis rates, which might also be expected to show different sensitivities to the nutritional toxin, ethanol. To test this, we dosed male Wistar rats with ethanol (75 mmol/kg body weight) and measured rates of protein synthesis (ie, the fractional rate of protein synthesis, defined as the percentage of the protein pool renewed each day; k(s), %/d) in different brain regions 2.5 hours later with the flooding dose method using L-[4-(3)H] phenylalanine. In the event that some regions were refractory to the deleterious effects of ethanol, we also predosed rats with cyanamide, an aldehyde dehydrogenase inhibitor (ie, cyanamide + ethanol), to increase endogenous acetaldehyde, a potent neurotoxic agent. The results indicated the mean fractional rates of protein synthesis in the cortex was 21.1%/d, which was significantly lower than either brain stem (30.2%/d, P <.025), cerebellum (30.1%/d, P <.01), or midbrain (29.8%, P <.025). Ethanol significantly decreased protein synthesis in the cortex (21%, P < 0.01), cerebellum (19%, P <.025), brain stem (44%, P <.025), but not in the midbrain (not significant [NS]). However, significant reductions in protein synthesis in the midbrain occurred in cyanamide + ethanol-dosed rats (60%, P <.0001). Cyanamide + ethanol treatment also reduced k(s) in the brain stem (66%, P <.001), cortex (59%, P <.001), and cerebellum (55%, P <.001). In conclusion, the applicability of the flooding dose technique to measure protein synthesis in the brain in vivo is demonstrated by its ability to measure regional difference. Impaired protein synthesis rates may contribute to or reflect the pathogenesis of alcohol-induced brain damage.

ABSTRACT

MOTIVATION: The methods for analyzing overlap data are distinct from those for analyzing probe data, making integration of the two forms awkward. Conversion of overlap data to probe-like data elements would facilitate comparison and uniform integration of overlap data and probe data using software developed for analysis of STS data. RESULTS: We show that overlap data can be effectively converted to probe-like data elements by extracting maximal sets of mutually overlapping clones. We call these sets virtual probes, since each set determines a site in the genome corresponding to the region which is common among the clones of the set. Finding the virtual probes is equivalent to finding the maximal cliques of a graph. We modify a known maximal-clique algorithm such that it finds all virtual probes in a large dataset within minutes. We illustrate the algorithm by converting fingerprint and Alu-PCR overlap data to virtual probes. The virtual probes are then analyzed using double-linkage intersection graphs and structure graphs to show that methods designed for STS data are also applicable to overlap data represented as virtual probes. Next we show that virtual probes can produce a uniform integration of different kinds of mapping data, in particular STS probe data and fingerprint and Alu-PCR overlap data. The integrated virtual probes produce longer double-linkage contigs than STS probes alone, and in conjunction with structure graphs they facilitate the identification and elimination of anomalies. Thus, the virtual-probe technique provides: (i) a new way to examine overlap data; (ii) a basis on which to compare overlap data and probe data using the same systems and standards; and (iii) a unique and useful way to uniformly integrate overlap data with probe data.

ABSTRACT

A new method for separation and purification is described. The process, referred to as solid-phase precipitation and extraction (SPPE), was developed and applied to postcleavage isolation of synthetic peptides. The technique uses normal approaches of chromatography and solid-phase extraction sorbents with a precipitation or drying procedure so that the sorbent becomes a support matrix for thin-film deposition of the compounds of interest. This procedure causes precipitated compounds of interest to be trapped on the large surface area or in the pores of the matrix so that by-products and impurities can be removed by strong wash solvents. In application to solid-phase peptide synthesis chemistry, by-products from the cleavage and deprotection are selectively extracted from the crude sample mixture under mild conditions. In comparison to the ether precipitation method used in peptide chemistry, the SPPE process provides isolated products that are 14-17% (w/w) higher purity.

ABSTRACT

A pilot study was conducted to investigate the hypothesis that dietary tryptophan manipulation would influence self-report affective status in alcoholic males. No significant effect of dietary manipulation was observed on the tryptophan/large neutral amino acids ratio or psychological indices of affect. The notion that dietary manipulation may be utilized in improving mood state in alcoholic males was not supported.

ABSTRACT

This paper explores the development and implementation of specific criteria to determine the level of clinical performance of postgraduate nursing students during the first year of a Master of Nursing course. The authors describe two commonly used clinical skill assessment tools and identify limitations of these tools for postgraduate nursing students. As a result of these limitations, Clinical Assessment Criteria (CAC) utilising the framework of Benner (1984) was developed. Inherent within the CAC is four levels of clinical nursing performance, which enable the nurse teacher and student to monitor the progression from novice to proficient levels of practice within a specialty area. Following a successful pilot study, the CAC was incorporated into clinical assessments in nine specialty postgraduate courses. Furthermore, the framework developed for the CAC can also be integrated into a variety of professional development domains.
