241 IMPLEMENTATION OF AN INTRACEREBRAL CEREBRAL HAEMORRHAGE CARE BUNDLE

Background

Mortality for Intracerebral haemorrhage (ICH) is 31% (Irish National Audit Stroke, 2019). An ICH care bundle focusing on acute anticoagulation reversal, blood pressure lowering, and a neurosurgical care pathway was associated with improved survival. Translating evidence-based medicine into clinical practice is challenging. The aim of this study was to determine feasibility and outcomes of implementation of a care bundle.

Methods

An ICH care bundle was developed using an iterative process involving expert stakeholder review of the evidence-based literature. A pre-and-post quasi-experimental research design was employed to evaluate this intervention. Baseline data were collected before implementation (January 2016-June 2018). Implementation took place in a staged manner in a single university teaching hospital with multiple ‘Plan Do Study Act cycles’ (June 2018 to January 2021). Data on compliance, process measures and outcomes were collected.

Results

Systolic blood pressure (first 24-hours) and anticoagulant reversal were significantly better controlled post-implementation (χ2 (1, N = 91) = 5.34, P = 0.02), (χ2 (1, N = 25) = 5.85, P = 0.016), respectively. DNAR orders were significantly lower in the post-implementation group (χ2 (1, N = 25) = 5.85, P = 0.029). However, ‘Do Not Actively Resuscitate’ status did not significantly differ when accounting for low GCS as a surrogate measure for poor prognosis (χ2 (1, N = 34) = 0.00, P = 0.966). Modified Rankin Scale on discharge did not differ significantly pre-and-post-implementation (z = −0.075, P = 0.94). A greater proportion of patients survived in the post-implementation group; however, this was not statistically significant (χ2 (1, N = 133) = 0.77, P = 0.38). Length of stay significantly increased post implementation.

Conclusion

An ICH care bundle was developed based on expert stakeholder feedback. The feasibility of implementing this bundle of care was demonstrated in a real-world clinical practice setting. A cluster-randomized trial or a large registry study is the next step to evaluate the overall impact of this care bundle on patient outcomes.

Deciding to discontinue prescribed psychotropic medication: A qualitative study of service users' experiences

Many mental health service users decide to discontinue their psychotropic medication at some stage in the treatment process; however, few studies have captured these experiences. This study aimed to explore people's experiences of coming off medication. A qualitative descriptive design and individual interviews with 23 people who experienced coming off medication were employed. COREQ checklist was used. Data were analysed using inductive and deductive approaches and six major themes were developed. Findings suggest that while medication was useful for many in the short-term, the adverse effects had significant impact and contributed to the decision to come off medication. Participants also reported being driven by a questioning of the biomedical model of treatment and the belief that there were other strategies to manage their distress. Mixed experiences of support from healthcare professionals for the medication cessation process were reported. The discontinuation process was often difficult resulting in changes in mood and behaviour which for many culminated in relapse of distress, rehospitalization and return to medication. To support the process of coming off and staying off medication, participants identified a range of useful strategies but particularly highlighted the importance of peer support. Findings from this study demonstrate the importance of mental health nurses having a collaborative discussion with service users which may support safer decision-making and lessen the risk of people discontinuing medication abruptly. Finding also indicates a need for robust studies that develop and test interventions to support people who wish to discontinue psychotropic medications.

Mental health service users experiences of medication discontinuation: a systematic review of qualitative studies

BACKGROUND

The use of psychotropic medication is often the first line of treatment for people with mental distress. However, many service users discontinue their prescribed medication, and little is known about their experiences or the reasons why they choose to stop taking medication.

AIM

The aim of this review is to synthesize research literature focused on the experiences of people who decided to discontinue taking medication for their mental health problem.

METHODS

A systematic review of qualitative studies was conducted. Data bases were searched for qualitative research which explored participants' motivations for discontinuing medication and their experiences of the process.

RESULTS

Six themes were identified: (1) Taking medications: a loss of autonomy, (2) Discontinuing medication: a thought-out process, (3) Factors influencing the decision to discontinue medication, (4) Discontinuing medication: experiences of the process, (5) Outcomes of discontinuing medication, (6) Managing mental distress in the absence of medication.

CONCLUSION

Service providers need to be aware that for some service user's psychotropic medication is not deemed a suitable treatment approach. Those who wish to discontinue medication need to be supported in the context of positive, therapeutic risk where their mental and physical health can be monitored and the likelihood of success increased.

Predictors of recovery following allogeneic CD34+-selected cell infusion without conditioning to correct poor graft function

Poor graft function is a serious complication following allogeneic hematopoietic stem cell transplantation. Infusion of CD34+-selected stem cells without pre-conditioning has been used to correct poor graft function, but predictors of recovery are unclear. We report the outcome of 62 consecutive patients who had primary or secondary poor graft function who underwent a CD34+-selected stem cell infusion from the same donor without further conditioning. Forty-seven of 62 patients showed hematological improvement and became permanently transfusion and growth factor-independent. In multivariate analysis, parameters significantly associated with recovery were shared CMV seronegative status for recipient/donor, the absence of active infection and matched recipient/donor sex. Recovery was similar in patients with mixed and full donor chimerism. Five -year overall survival was 74.4% (95% CI 59-89) in patients demonstrating complete recovery, 16.7% (95% CI 3-46) in patients with partial recovery and 22.2% (CI 95% 5-47) in patients with no response. In patients with count recovery, those with poor graft function in 1-2 lineages had superior 5-year overall survival (93.8%, 95% CI 82-99) than those with tri-lineage failure (53%, 95% CI 34-88). New strategies including cytokine or agonist support, or second transplant need to be investigated in patients who do not recover.

Crude Fat, Diethyl Ether Extraction, in Feed, Cereal Grain, and Forage (Randall/Soxtec/Submersion Method): Collaborative Study

A method for determining crude fat in animal feed, cereal grain, and forage (plant tissue) was collaboratively studied. Crude fat was extracted from the animal feed, cereal grain, or forage material with diethyl ether by the Randall method, also called the Soxtec method or the submersion method. The proposed submersion method considerably decreases the extraction time required to complete a batch of samples. The increase in throughput is very desirable in the quest for faster turnaround times and the greater efficiency in the use of labor. In addition, this method provides for reclamation of the solvent as a step of the method. The submersion method for fat extraction was previously studied for meat and meat products and was accepted as AOAC Official Method 991.36. Fourteen blind samples were sent to 12 collaborators in the United States, Sweden, Canada, and Germany. The within-laboratory relative standard deviation (repeatability) ranged from 1.09 to 9.26% for crude fat. Among-laboratory (including within) relative standard deviation (reproducibility) ranged from 1.0 to 21.0%. The method is recommended for Official First Action.

Crude Fat, Hexanes Extraction, in Feed, Cereal Grain, and Forage (Randall/Soxtec/Submersion Method): Collaborative Study

A method for determining crude fat in animal feed, cereal grain, and forage (plant tissue) was collaboratively studied. Crude fat was extracted from the animal feed, cereal grain, or forage material with hexanes by the Randall method, also called the Soxtec method or the submersion method. The use of hexanes provides for an alternative to diethyl ether for fat extractions. The proposed submersion method considerably decreases the extraction time required to complete a batch of samples compared to Soxhlet. The increase in throughput is very desirable in the quest for faster turnaround times and the greater efficiency in the use of labor. In addition, this method provides for reclamation of the solvent as a step of the method. The submersion method for fat extraction was previously studied for meat and meat products and was accepted as AOAC Official Method 991.36. Fourteen blind samples were sent to 14 collaborators in the United States, Sweden, Canada, and Germany. The within-laboratory relative standard deviation (repeatability) ranged from 1.23 to 5.80% for crude fat. Among-laboratory (including within) relative standard deviation (reproducibility) ranged from 1.88 to 14.1%. The method is recommended for Official First Action.

How to deal with calcium in the superficial femoral artery

Despite the continuous evolution of endovascular therapy, severe calcification remains a major issue for the minimally invasive treatment of superficial femoral artery (SFA) disease. The presence of calcium might negatively affect both the crossing of peripheral lesions and outcomes of all available treatment modalities and is therefore associated with unfavorable acute and long-term results. This manuscript summarizes the challenges raised from severe calcified atherosclerotic lesions and presents the outcomes of the various endovascular modalities in the treatment of calcified SFA disease.

Effect of Continuous Digital Hypothermia on Lamellar Inflammatory Signaling When Applied at a Clinically-Relevant Timepoint in the Oligofructose Laminitis Model

BACKGROUND

Although continuous digital hypothermia (CDH) protects lamellae from injury in the oligofructose (OF) model of sepsis-related laminitis (SRL), conflicting results exist from these studies regarding effects of CDH on lamellar inflammatory events.

HYPOTHESIS/OBJECTIVES

To determine the effect of CDH on lamellar inflammatory events in normal and OF-treated horses when instituted at a clinically relevant time point (onset of clinical signs of sepsis in this model).

ANIMALS

Standardbred geldings (n = 15) aged 3-11 years were used.

METHODS

In a randomized, controlled discovery study, animals were administered either OF (OF group, n = 8) or water (CON group, n = 8) by nasogastric tube and CDH was initiated in one forelimb (ICE) 12 hours later. Lamellar tissue samples were collected 24 hours after initiation of CDH (ICE and ambient [AMB] forelimbs). Lamellar mRNA concentrations of inflammatory mediators and lamellar leukocyte numbers were assessed using qPCR and immunohistochemistry, respectively; values from four sample groups (CON AMB, OF AMB, CON ICE, and OF ICE) were analyzed using mixed model linear regression.

RESULTS

Although lamellar mRNA concentrations of multiple inflammatory mediators (IL-1β, IL-6, CXCL1, MCP2, COX-2) were increased after OF administration (OF AMB group versus CON AMB; P < 0.05), only 2 inflammatory mediators (IL-6 and COX-2) and lamellar leukocyte numbers were decreased with CDH (OF ICE versus OF AMB; P < 0.05).

CONCLUSIONS AND CLINICAL IMPORTANCE

Continuous digital hypothermia initiated at a time point similar to that commonly used clinically (clinical onset of sepsis) resulted in a more focused inhibition of inflammatory signaling.

UK consensus statement on the use of plerixafor to facilitate autologous peripheral blood stem cell collection to support high-dose chemoradiotherapy for patients with malignancy

Plerixafor is a CXC chemokine receptor (CXCR4) antagonist that mobilizes stem cells in the peripheral blood. It is indicated (in combination with granulocyte-colony stimulating factor [G-CSF]) to enhance the harvest of adequate quantities of cluster differentiation (CD) 34+ cells for autologous transplantation in patients with lymphoma or multiple myeloma whose cells mobilize poorly. Strategies for use include delayed re-mobilization after a failed mobilization attempt with G-CSF, and rescue or pre-emptive mobilization in patients in whom mobilization with G-CSF is likely to fail. Pre-emptive use has the advantage that it avoids the need to re-schedule the transplant procedure, with its attendant inconvenience, quality-of-life issues for the patient and cost of additional admissions to the transplant unit. UK experience from 2 major centers suggests that pre-emptive plerixafor is associated with an incremental drug cost of less than £2000 when averaged over all patients undergoing peripheral blood stem cell (PBSC) transplant. A CD34+ cell count of <15 µl^-1 at the time of recovery after chemomobilization or after four days of G-CSF treatment, or an apheresis yield of <1 × 10⁶ CD34+ cells/kg on the first day of apheresis, could be used to predict the need for pre-emptive plerixafor.

ANCA-negative Granulomatosis with Polyangiitis: A Difficult Diagnosis

Granulomatosis with polyangitiis (GPA) is a systemic small and medium vessel vasculitis, commonly associated with anti-neutrophil cytoplasmic antibodies (ANCAs). Presenting signs and symptoms in GPA are varied and patients may present with constitutional, non-specific symptoms, which can delay the diagnosis. Tissue biopsy of the site of active disease can confirm the diagnosis of GPA, in which necrotising granulomatous inflammation is seen. However, surrogate markers may be used for diagnosis without a tissue biopsy. They include upper and lower airway symptoms, signs of glomerulonephritis and a positive ANCA. However, approximately 10-20% of patients with GPA are ANCA negative, allowing for the diagnosis to be overlooked, particularly in those patients with non-specific findings. The reason for the absence of ANCAs is unclear.

LEARNING POINTS

A case of granulomatosis with polyangitiis presenting with non-specific findings is described.Some 10% of cases are ANCA negative.When a vasculitis is suspected, a negative ANCA does not exclude the diagnosis of GPA, so further investigations (i.e. tissue biopsy) should be considered.

Not Another ACS Rule Out

CASE

A 50 year old African-American woman with diabetes, hypertension, and hyperlipidemia presented with progressively worsening retro-sternal chest pain, exacerbated by activity and relieved by rest. She also endorsed a thirty-pound unintentional weight loss, and dysphagia. She was dysarthric with left-sided Bell's Palsy and a palpable left axillary lymph node. She had been evaluated at several hospitals in the previous months for similar typical chest pain. Her troponin values were normal, and an EKG showed T-wave inversions in leads I and aVL. On echocardiography, her ejection fraction was 45 percent with anterolateral hypokinesis. She was treated for NSTEMI, and an angiogram showed 95 percent stenosis of the right coronary artery. A modified barium swallow study revealed weakened swallowing with aspiration of thin liquids. An MRI Brain demonstrated scattered T2/ FLAIR hyper-intense foci in the subcortical white matter and focal meningeal thickening. ANA, dsDNA, ANCA, and Lyme antibodies were all negative, and a chest CT showed hilar lymphadenopathy. Cardiac MRI demonstrated scattered foci of delayed enhancement in the mid-myocardium and sub-epicardium without infarction. An endobronchial biopsy of hilar lymph nodes showed two small epithelioid granulomas, consistent with Sarcoidosis. She was started on high-dose corticosteroids with rapid improvement. A repeat modified barium swallow study was normal and a repeat echocardiogram demonstrated recovered ejection fraction of 55 percent with improved wall motion in the septum and apex. Additionally, her left-sided Bell's Palsy and dysarthria improved after several days of therapy.

DISCUSSION

To our knowledge, this report is the third case of multi-organ Sarcoidosis presenting as ACS. This case depicts the simultaneous presentation of neurologic, pharyngeal, pulmonary, and cardiac Sarcoidosis. Myocardial involvement in Sarcoidosis is rare and usually presents as conduction abnormalities with arrhythmia rather than ACS. Though her symptoms were consistent with Sarcoidosis, she had multiple risk factors for coronary atherosclerosis including diabetes, hypertension, and hyperlipidemia. This case highlights the importance of including Sarcoidosis in the differential diagnosis for patients with recurrent typical chest pain of uncertain etiology.

But is it science?

Early years science education is not science, but a curricular construction designed to induct young children into a range of ideas and practices related to the natural world. While inquiry-based learning is an important approach to this, it is not of itself unique to science and there are a range of logico-mathematical constructions that come closer to the essence of science. In this paper we discuss just three: empirical question-asking, transgressive play, and good thinking. The challenge, of course is to induct early years practitioners to a different way of shaping early science.

Effect of Delayed Digital Hypothermia on Lamellar Inflammatory Signaling in the Oligofructose Laminitis Model

Background

In the oligofructose (OF) model of sepsis‐related laminitis (SRL), digital hypothermia (“cryotherapy”) initiated before the onset of clinical signs is reported not only to limit lamellar injury, but also to cause marked inhibition of lamellar inflammatory signaling.

Hypothesis/Objectives

Because hypothermia also has been reported to be protective when not initiated until the onset of lameness in the OF model of SRL, we hypothesized that the lamellar protection conferred by hypothermia is caused by local lamellar inhibition of inflammatory signaling as described when hypothermia was initiated earlier in the disease process.

Animals

Eight Standardbred geldings aged 3–11 years with no lameness and no abnormalities of the feet detectable by gross or radiographic examination.

Methods

Using the OF model of SRL, lamellar mRNA concentrations of proinflammatory cytokines, chemokines, and endothelial adhesion proteins were compared between samples from treated limbs (CRYO, submerged in ice water for 36 hour starting at the onset of lameness), untreated limbs (NON‐CRYO, opposite limb from CRYO limbs maintained at ambient temperature), and untreated limbs from normal horses in which laminitis was not induced (CON).

Results

Although OF administration resulted in increases in lamellar mRNA concentrations of several inflammatory mediators in NON‐CRYO limbs (vs CON), digital hypothermia had no significant effect on these increases.

Conclusions and Clinical Importance

The lack of inflammatory inhibition in lamellar tissue samples in our study indicates that the protective effects of digital hypothermia instituted at the onset of clinical signs of laminitis do not arise from inhibition of inflammatory pathways.

Informing etiologic research priorities for squamous cell esophageal cancer in Africa: A review of setting-specific exposures to known and putative risk factors

Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers in most Eastern and Southern African countries, but its etiology has been understudied to date. To inform its research agenda, we undertook a review to identify, of the ESCC risk factors which have been established or strongly suggested worldwide, those with a high prevalence or high exposure levels in any ESCC-affected African setting and the sources thereof. We found that for almost all ESCC risk factors known to date, including tobacco, alcohol, hot beverage consumption, nitrosamines and both inhaled and ingested PAHs, there is evidence of population groups with raised exposures, the sources of which vary greatly between cultures across the ESCC corridor. Research encompassing these risk factors is warranted and is likely to identify primary prevention strategies.

A Direct Oral Anticoagulant as a Cost Effective Alternative to Warfarin for Treatment of Provoked Venous Thrombosis

In Ireland, Warfarin is the primary anticoagulant prescribed in the secondary prevention of provoked DVT. We completed a comprehensive cost analysis of a trial group of 24 patients treated with Rivaroxaban (between November 2013 and December 2014), versus a control group treated with Warfarin (between January 2008 and November 2013). The groups were matched for gender (3/7 M/F ratio), DVT type (5 proximal, 19 distal DVTs), provoking factor (20 traumatic, 4 atraumatc), and age. We calculated the cost for each group based on drug administration and clinic costs (labour, sample analysis, and additional costs). Warfarin patients attended clinic 14.58 times; Rivaroxaban patients attended 2.92 times. Overall, the cost per patient on Rivaroxaban is €273.30 versus €260.68 with warfarin. This excludes patient costs which would further increase cost of Warfarin therapy.

Reflective Questions, Self-Questioning and Managing Professionally Situated Practice

Reflective self-questioning arises within the workplace when people are confronted with professional problems and situations. This paper focuses on reflective and ‘situated reflective’ questions in terms of self-questioning and professional workplace problem solving. In our view, the situational context, entailed by the setting, social and personal/individual perspectives, is interactional. The supporting empirical data is drawn from our work with two groups in their tertiary phase of education: professional trainers within a large corporate organisation and para-professionals within a large college system; each embraces phenomenological principles. The discussions of situated reflective practice (SRP) entail those circumstances where change is visited upon the individual by forces outside their immediate control. The positive sense of SRP is that it can prepare an individual for anticipated change, and is therefore considered a method of change management. The situation acts as a catalyst for the thought.

What are the risks and knowledge deficits for prescribing and administering opioids in the ward environment? A quality project on assessing and improving knowledge

Investigations into Medical Emergency Team (MET) calls and related clinical incident reviews at a large district teaching hospital provided evidence that over sedation can be a significant issue post opioid administration and that safe and effective pain management requires accurate opioid knowledge and patient assessment skills. The aim of the study was to develop education that was directed at identified knowledge deficits, and to evaluate the impact of this tailored education program on knowledge of safe prescribing and administration of opioids. Knowledge levels were explored using a structured questionnaire in a pre and post-test design. A convenience sample of 34 nurses and 5 junior medical officers across three surgical wards in a tertiary referral hospital had their knowledge assessed. Results showed significant improvement when repeat questionnaires were given two weeks post-delivery of education. Mean scores were 68% at baseline and 89% two weeks post completion of the education program. The greatest improvement in scores was recorded for drug knowledge including dose, half-life and administration. The findings from this study suggest that the opioid education program is effective in improving the knowledge of safe prescribing and administration of opioids, however further studies are required.

Delayed seizure-like activity following analytically confirmed use of previously unreported synthetic cannabinoid analogues

Synthetic cannabinoid use has become widespread, leading to increased burdens on health care providers. Symptoms range from agitation and psychosis to seizures and acute kidney injury. We report a case where a patient was assessed and treated twice within 12 h for seizures following synthetic cannabinoid intoxication. Blood sample determinations showed low concentrations of analogues not previously reported, some of which are legal. Clinicians should be aware that synthetic cannabinoids may cause an array of severe health consequences. Given the ever evolving structure of available analogues, clinicians must also be prepared for other unexpected adverse effects.

Inflammatory bowel disease and thromboembolism. Is inflammation at the centre of the clot?

Thromboembolic events are well recognised in patients with inflammatory bowel disease (IBD). We present three cases which highlight the need for vigilance with respect to this complication. We also propose that consideration be given to re-evaluating disease activity in those patients who develop thromboembolic complications.

A survey of pedagogical approaches and quality mechanisms used in education programs for mental health professionals

The provision of high-quality education and training that is responsive, relevant, accessible and evidence based is critical if the vision for quality mental health services presented in recent policy initiatives in Ireland is to be fulfilled. This paper reports the findings related to pedagogical approaches and quality assurance mechanisms utilized within mental health education. The study involved canvassing all Higher Education Institutions in Ireland. A total of 227 courses in 31 educational institutes were identified and 149 questionnaires were returned from 129 Course Coordinators. Various quality processes were identified in existing programs; however, formal feedback from service providers, service users and carers was seldom reported. Ongoing evaluation and quality assurance strategies are a key element of governance and there is a need to develop strategies that explore the impact of education programs on mental health education and health outcomes. Recommendations are made in terms of future interprofessional mental health education and practice.

Service user involvement in mental health practitioner education in Ireland

In recent years, there is an ever increasing call to involve people who use mental health services in the development, delivery and evaluation of education programmes. Within Ireland, there is very little evidence of the degree of service user involvement in the educational preparation of mental health practitioners. This paper presents the findings on service user involvement in the education and training of professionals working in mental health services in Ireland. Findings from this study indicate that in the vast majority of courses curricula are planned and delivered without consultation or input from service users. Currently the scope of service user involvement is on teaching, with little involvement in curriculum development, student assessment and student selection. However, there is evidence that this is changing, with many respondents indicating an eagerness to move this agenda forward.

Laminar inflammatory gene expression in the carbohydrate overload model of equine laminitis

REASONS FOR PERFORMING STUDY

There is a need to assess the laminar inflammatory response in a laminitis model that more closely resembles clinical cases of sepsis-related laminitis than the black walnut extract (BWE) model.

OBJECTIVES

To determine if a similar pattern of laminar inflammation, characterised by proinflammatory cytokine expression, occurs in the CHO model of laminitis as has been previously reported for the BWE model.

METHODS

Sixteen horses administered 17.6 g of starch (85% corn starch/15% wood flour)/kg bwt via nasogastric (NG) tube were anaesthetised either after developing a temperature>38.9°C (DEV group, n=8) or at onset of Obel grade 1 lameness (OG1 group, n=8). Control horses (CON group, n=8) were anaesthetised 24 h after NG administration of 6 l of deionised water. Laminar tissue was collected from horses while under anaesthesia, followed by humane euthanasia. Real time-quantitative PCR was used to assess laminar mRNA concentrations of genes involved in inflammatory signalling.

RESULTS

Increased mRNA concentrations (P<0.05) for IL-1β, IL-6, IL-12p35, COX-2, E-selectin and ICAM-1 were present in laminae from horses with OG1 lameness but not at the DEV time, when compared to the CON horses. No differences between the groups were found for IL-2, IL-4, IL-10, TNF-α, IFN-γ or COX-1 at either the DEV or OG1 time points.

CONCLUSIONS

There was a notable difference in the temporal pattern of inflammatory events between the BWE and CHO models, with the majority of laminar inflammatory events appearing to occur at or near the onset of lameness in the CHO model, whereas many of these events peak earlier in the developmental stages in the BWE model. This suggests that, in addition to circulating inflammatory molecules, there may be a local phenomenon in the CHO model resulting in the simultaneous onset of multiple laminar events including endothelial activation, leucocyte emigration and proinflammatory cytokine expression.

POTENTIAL RELEVANCE

The similar (although somewhat delayed) inflammatory response in the CHO model of laminitis indicates that inflammatory signalling is a consistent entity in the pathophysiology of laminitis.
