    Storytelling at board meetings: A case study of co-developing recommendations

    Get PDF
    In healthcare, stories shared by patients often provide details and insights into experiences of illness and care. Stories are a way to educate healthcare providers and others to improve care and systems to become more patient and family centred and to better meet patients’ needs and priorities. Telling stories may bring benefits to both storytellers and audience members but also presents risks of harm. A reflective storytelling practice aims to honor stories and storytellers by ensuring there is time to prepare, reflect, learn, ask questions, and engage in dialogue with the storyteller to explore what went well and where there are learning and improvement opportunities. Healthcare Excellence Canada (HEC) is a pan-Canadian health organization focused on improving the quality and safety of care in Canada. HEC commits to engage patients, caregivers, and communities and aims to develop practices and structures to enable engagement activities. At the request of the HEC Board, the Patient Engagement and Partnerships team co-developed recommendations on the process for how best to meaningfully share stories at Board meetings, including stories from those leading, providing, and receiving care. This Case Study outlines the process HEC used to co-develop storytelling recommendations, focusing on a trauma-informed approach to create safe spaces for preparing, learning from and reflecting on stories, to clearly articulate their purpose, and to ensure the locus of control for storytelling rests with the storytellers. This Case Study shares these recommendations and invites other organizations to use these recommendations and/or adapt them within their own context.

    A Long Spell of Uncertainity

    We find ourselves in a period of sustained economic uncertainty. Today, like 6 months ago, the U.S. economy is on the brink of a recession. Weakness in lending activity, coupled with weakness in the housing sector and related manufacturing industries has stymied economic growth since late 2007. At times, recession seems imminent. But, the official measures, such as quarterly gross domestic product, do not clearly signal that the economy is contracting. Further, prices are rising rapidly for food and energy. That is the uncertainty. Will 2008 be remembered as a recession year, or as a period of disappointing but slow growth? And, will 2008 be known as the year when inflation reignited in America. In some sense, the answer does not matter. The United States and its citizens already are experiencing some of the consequences of recession, and of higher inflation. Job counts are declining and unemployment is rising. Many face the prospect of losing their homes. Prices including food and energy are rising 2% faster than in most recent years. But, of course, the answer matters quite a lot. If the U.S. economy falls into recession, or if a recession has already begun, job losses will accelerate and unemployment will rise sharply. The real estate and financial markets may spiral down faster. There is also a risk that prices increases will accelerate if inflation in food and energy spreads into wage inflation impacting a broad spectrum of sectors. Our view is that the economy will avoid both a significant recession and rapid inflation. Strong exports will encourage growth, and consumers and the financial sector will slowly work their way through their current difficulties. Inflation largely will be contained to the food and energy sectors. But, the scenario is far from rosy. We expect weak economic growth through 2008 and early 2009, and elevated inflation rates through 2010. In particular, we expected annual growth in real GDP of 1.1% in 2008, 1.7% in 2009. GDP growth rates only returns to trend growth of 2.8% in 2010. Inflation will hit 4.0% in 2008, and will be well above 2% in subsequent years, at 2.6% in 2009, and 2.7% in 2010. A significant slowdown will be avoided because the weak dollar will encourage strong exports, and because consumer spending will expand modestly despite a weak employment situation and high energy prices. Consumer confidence has declined rapidly but consumer spending should stay steady thanks to lower interest rates, and in the very short-term, federal government rebate checks. Current high energy prices also are expected to stabilize, and therefore, will not cause even further strain on consumer spending for other goods and services. This relatively positive scenario naturally assumes that the U.S. economy will avoid other major dislocations. The economy may fall into a significant recession if there are other major disruptions in the financial system that limit access to capital. Inflation may spike further if oil prices rise or additional weather causes further increases in food prices

    Prophylactic plasma exchange in CD46-associated atypical haemolytic uremic syndrome

    Get PDF
    Patients with atypical haemolytic uremic syndrome (aHUS) with a mutation in the gene encoding membrane cofactor protein (CD46) are known to have a better prognosis than those with mutations in factor H (CFH) or factor I (CFI), but a small number of the former still proceed to end-stage renal failure. Plasma therapy (PE) is the recommended approach to treat both acute episodes and prevent recurrences in aHUS, but studies have yet to show PE efficacy in aHUS associated with a CD46 mutation. The factors determining failure to treatment are not clear and may be related to the mutation involved or to insufficient treatment. Our experience of PE in a family of three sisters with CFH-associated aHUS suggests that intensive and prophylactic PE allows renal function to be maintained in both native kidneys and allografts. The success of this strategy has led us to use it in all cases of aHUS. Here, we describe the effect of this strategy in a child with aHUS and a CD46 mutation. The initial episode was treated with daily PE, resulting in the recovery of renal function. However, over the next 4 years, there was a progressive decline in renal function to end-stage renal failure, with evidence of an on-going thrombotic microangiopathy despite continuous prophylactic PE. Prophylactic PE does not influence the natural course of aHUS and CD46 mutation

    Deletion of Complement Factor H–Related Genes CFHR1 and CFHR3 Is Associated with Atypical Hemolytic Uremic Syndrome

    Atypical hemolytic uremic syndrome (aHUS) is associated with defective complement regulation. Disease-associated mutations have been described in the genes encoding the complement regulators complement factor H, membrane cofactor protein, factor B, and factor I. In this study, we show in two independent cohorts of aHUS patients that deletion of two closely related genes, complement factor H–related 1 (CFHR1) and complement factor H–related 3 (CFHR3), increases the risk of aHUS. Amplification analysis and sequencing of genomic DNA of three affected individuals revealed a chromosomal deletion of ∼84 kb in the RCA gene cluster, resulting in loss of the genes coding for CFHR1 and CFHR3, but leaving the genomic structure of factor H intact. The CFHR1 and CFHR3 genes are flanked by long homologous repeats with long interspersed nuclear elements (retrotransposons) and we suggest that nonallelic homologous recombination between these repeats results in the loss of the two genes. Impaired protection of erythrocytes from complement activation is observed in the serum of aHUS patients deficient in CFHR1 and CFHR3, thus suggesting a regulatory role for CFHR1 and CFHR3 in complement activation. The identification of CFHR1/CFHR3 deficiency in aHUS patients may lead to the design of new diagnostic approaches, such as enhanced testing for these genes

    The LIGO Laboratory 40m prototype interferometer at Caltech is being commissioned to prototype an optical configuration for Advanced LIGO. This optical configuration has to control five length degrees of freedom, and its control topology will be significantly more complicated than any other present interferometers. This paper explains the method of sensing, controls and lock acquisition

    Plasma therapy in atypical haemolytic uremic syndrome: lessons from a family with a factor H mutation

    Whilst randomised control trials are undoubtedly the best way to demonstrate whether plasma exchange or infusion alone is the best first-line treatment for patients with atypical haemolytic uremic syndrome (aHUS), individual case reports can provide valuable information. To that effect, we have had the unique opportunity to follow over a 10-year period three sisters with aHUS associated with a factor H mutation (CFH). Two of the sisters are monozygotic twins. A similar natural evolution and response to treatment would be expected for the three patients, as they all presented with the same at-risk polymorphisms for CFH and CD46 and no identifiable mutation in either CD46 or CFI. Our report of different modalities of treatment of the initial episode and of three transplantations and relapses in the transplant in two of them, strongly suggest that intensive plasma exchange, both acutely and prophylactically, can maintain the long-term function of both native kidneys and allografts. In our experience, the success of plasma therapy is dependent on the use of plasma exchange as opposed to plasma infusion alone, the prolongation of daily plasma exchange after normalisation of haematological parameters followed by prophylactic plasma exchange, the use of prophylactic plasma exchange prior to transplantation and the use of prophylactic plasma exchange at least once a week posttransplant with immediate intensification of treatment if there are any signs of recurrence

    Atypical Haemolytic Uraemic Syndrome Associated with a Hybrid Complement Gene

    BACKGROUND: Sequence analysis of the regulators of complement activation (RCA) cluster of genes at chromosome position 1q32 shows evidence of several large genomic duplications. These duplications have resulted in a high degree of sequence identity between the gene for factor H (CFH) and the genes for the five factor H-related proteins (CFHL1–5; aliases CFHR1–5). CFH mutations have been described in association with atypical haemolytic uraemic syndrome (aHUS). The majority of the mutations are missense changes that cluster in the C-terminal region and impair the ability of factor H to regulate surface-bound C3b. Some have arisen as a result of gene conversion between CFH and CFHL1. In this study we tested the hypothesis that nonallelic homologous recombination between low-copy repeats in the RCA cluster could result in the formation of a hybrid CFH/CFHL1 gene that predisposes to the development of aHUS. METHODS AND FINDINGS: In a family with many cases of aHUS that segregate with the RCA cluster we used cDNA analysis, gene sequencing, and Southern blotting to show that affected individuals carry a heterozygous CFH/CFHL1 hybrid gene in which exons 1–21 are derived from CFH and exons 22/23 from CFHL1. This hybrid encodes a protein product identical to a functionally significant CFH mutant (c.3572C>T, S1191L and c.3590T>C, V1197A) that has been previously described in association with aHUS. CONCLUSIONS: CFH mutation screening is recommended in all aHUS patients prior to renal transplantation because of the high risk of disease recurrence post-transplant in those known to have a CFH mutation. Because of our finding it will be necessary to implement additional screening strategies that will detect a hybrid CFH/CFHL1 gene

    Orbital effects of a monochromatic plane gravitational wave with ultra-low frequency incident on a gravitationally bound two-body system

    Full text link
    We analytically compute the long-term orbital variations of a test particle orbiting a central body acted upon by an incident monochromatic plane gravitational wave. We assume that the characteristic size of the perturbed two-body system is much smaller than the wavelength of the wave. Moreover, we also suppose that the wave's frequency is much smaller than the particle's orbital one. We make neither a priori assumptions about the direction of the wavevector nor on the orbital geometry of the planet. We find that, while the semi-major axis is left unaffected, the eccentricity, the inclination, the longitude of the ascending node, the longitude of pericenter and the mean anomaly undergo non-vanishing long-term changes. They are not secular trends because of the slow modulation introduced by the tidal matrix coefficients and by the orbital elements themselves. They could be useful to indepenedently constrain the ultra-low frequency waves which may have been indirectly detected in the BICEP2 experiment. Our calculation holds, in general, for any gravitationally bound two-body system whose characteristic frequency is much larger than the frequency of the external wave. It is also valid for a generic perturbation of tidal type with constant coefficients over timescales of the order of the orbital period of the perturbed particle.Comment: LaTex2e, 24 pages, no figures, no tables.
