A Feasibility Study of Lavender Aromatherapy in an Awake Craniotomy Environment.

PURPOSE: Integrative medicine interventions are needed for awake craniotomies, as many patients experience anxiety. Lavender aromatherapy significantly reduces anxiety or pain in a variety of surgical procedures. This feasibility study used lavender aromatherapy during awake craniotomies to determine the number of patients who would consent and complete the study, the technicality of lavender aromatherapy use, and acceptance by operating room (OR) staff. METHODS: We approached 40 consecutive patients (≥18 years old). Exclusion criteria were pulmonary issues or sensitivity to lavender. Outcome measures in consented patients were enrollment and completion rates, anxiety and pain as measured by the Visual Analog Scale for Anxiety (VAS-A) and Visual Analog Scale for Pain (VAS-P), and satisfaction with pain control using the Patient Opinion of Pain Management (POPM) survey. RESULTS: Of the 40 patients approached, 4 declined participation or had their surgery cancelled. Of the remaining 36, 4 required increased sedation during surgery and 1 was unable to detect lavender. Thus, 31 patients (77.5%) completed the study. VAS-A and VAS-P scores trended lower after lavender inhalation, but the difference did not reach statistical significance. There was a slight increase in VAS-P score at the OR1 time point. Expectancy for reduction in both anxiety and pain were not significantly different. Improvement in anxiety also was not different, while improvement in pain trended lower (P=0.025). POPM results indicated the majority of patients were either "satisfied" or "very satisfied" with pain management. CONCLUSIONS: This study demonstrated 77.5% completion and the ability to integrate lavender aromatherapy into the OR. Thus, we plan to conduct a randomized clinical trial to assess efficacy of lavender aromatherapy.

Cost-Utility Analysis of Mechanical Thrombectomy Using Stent Retrievers in Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: Recently, 5 randomized controlled trials demonstrated the benefit of endovascular therapy compared with intravenous tissue-type plasminogen activator in acute stroke. Economic evidence evaluating stent retrievers is limited. We compared the cost-effectiveness of intravenous tissue-type plasminogen activator alone versus mechanical thrombectomy and intravenous tissue-type plasminogen activator as a bridging therapy in eligible patients in the UK National Health Service. METHODS: A model-based cost-utility analysis was performed using a lifetime horizon. A Markov model was constructed and populated with probabilities, outcomes, and cost data from published sources, including 1-way and probabilistic sensitivity analysis. RESULTS: Mechanical thrombectomy was more expensive than intravenous tissue-type plasminogen activator, but it improved quality-adjusted life expectancy. The incremental cost per (quality-adjusted life year) gained of mechanical thrombectomy over a 20 year period was $11 651 (£7061). The probabilistic sensitivity analysis demonstrated that thrombectomy had a 100% probability of being cost-effective at the minimum willingness to pay for a quality-adjusted life year commonly used in United Kingdom. CONCLUSIONS: Although the upfront costs of thrombectomy are high, the potential quality-adjusted life year gains mean this intervention is cost-effective. This is an important factor for consideration in deciding whether to commission this intervention.

What is known about adverse events in older medical hospital inpatients? A systematic review of the literature.

PURPOSE: Large international studies have shown that older hospital inpatients are at particular risk of adverse events. The purpose of this review was to synthesize data from studies designed to assess the scale and nature of this harm, with the ultimate aim of informing the development of new safety and quality measurement tools to facilitate improved hospital care for these vulnerable patients. DATA SOURCES STUDY SELECTION: and data extraction A systematic search using Ovid SP and other sources was carried out, rigorous inclusion and exclusion criteria were applied and quality assessment of included studies was conducted. Data were synthesized to give a picture of the incidence, types, causes, preventability and outcomes of adverse events in older medical inpatients. RESULTS OF DATA SYNTHESIS: Nine relevant studies were identified. A wide range of adverse event incidences were reported, from 5.29 to 6.2% in re-analyses of large adverse event studies, to 60% in studies in which the development of 'geriatric syndromes' (e.g. falls, delirium, incontinence) was also considered to be adverse events. Important causative factors other than age included clinical complexity, co-morbidity, illness severity, reduced functional ability and lower quality of care. Adverse events in older people lead to unnecessary interventions with resultant complications and increased length of stay. CONCLUSION: More work is needed to understand the complex nature of adverse events in older inpatients. We must tailor safety measurement and improvement strategies to address challenges presented by the complexity of the geriatric syndromes and the processes of care encountered by older inpatients.

Renal impairment reduces the efficacy of thrombolytic therapy in acute ischemic stroke.

BACKGROUND: Renal impairment is a potent risk factor for stroke, which remains a leading cause of death and disability. Thrombolysis for acute ischemic stroke has transformed patient outcomes, although the safety and efficacy of this approach remain poorly characterized in patients with renal dysfunction, who manifest a higher risk of bleeding due to uremia. We therefore examined the impact of renal impairment on clinical outcomes with thrombolysis within the current 4.5-hour therapeutic window. METHODS: This retrospective multicenter cohort study (2009-2011) examined 229 stroke patients receiving thrombolysis with alteplase (0.9 mg/kg; mean age 70 ± 13 years; 59% male, 24% diabetic). Sixty-five patients had an estimated glomerular filtration rate (eGFR) <60 ml/min. The primary outcome was the improvement in National Institutes of Health Stroke Scale (NIHSS) score at 24 h. Secondary outcomes included the NIHSS score at 7 days, the incidence of symptomatic and asymptomatic intracranial hemorrhage (ICH), extracranial bleeding and death during the index hospitalization. Univariate and multivariate regression analyses were performed to determine the association between demographic characteristics and comorbid factors of interest and outcomes. eGFR was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation. RESULTS: There was no significant difference in mean time to thrombolysis between the groups (221 ± 66 vs. 220 ± 70 min from symptom onset; p = 0.9). An eGFR <60 ml/min was independently associated with a statistically significant reduction of the therapeutic effect of alteplase at 24 h on multivariate regression [coefficient -2.3, 95% confidence interval (CI) -3.7 to -0.9; p = 0.002], and this persisted at 7 days (coefficient -3.5, 95% CI -5.3 to -1.7; p < 0.001). On modeling eGFR as a continuous variable, every 10 ml/min decline in eGFR was associated with a 0.40 diminution in NIHSS score improvement with alteplase (95% CI 0.07-0.74; p = 0.02). Older age and a higher presenting NIHSS score were associated with a greater therapeutic effect (p = 0.04 and p < 0.001, respectively). In-patient mortality was 5%, with no significant differences between groups. Renal impairment was not associated with a higher rate of ICH (6.2 vs. 6.7%; p = 0.9). Greater NIHSS score at presentation was the only factor associated with a greater risk of death (odds ratio 1.24, 95% CI 1.10-1.40; p < 0.001) and ICH (odds ratio 1.12, 95% CI 1.03-1.23; p = 0.004). CONCLUSIONS: Our results suggest that renal impairment is associated with reduced efficacy of thrombolysis in acute ischemic stroke without any excess hemorrhagic complications. This may relate to diminished fibrinolysis in the uremic milieu or differences in infarct anatomy. Longer-term prospective studies are required to characterize and improve functional outcomes following stroke in a manifestly high-risk group.

Mild stroke symptoms as the initial presentation of a patient with underlying subacute bacterial endocarditis.

We describe a patient with sub-acute bacterial endocarditis, whose chief presenting feature was mild expressive dysphasia.

The uses of aromatherapy in women's health.

Aromatherapy is the practice of therapeutic use of essential plant-based oils. Essential oils and aromatherapy have been used in the care of women for centuries. The published research has used small samples and often combines other complementary therapies with aromatherapy; however, the use of essential oils has not been shown to cause harm and is accepted by women. Aromatherapy mixtures are appropriate for use by nurses in labor and delivery settings. The article reviews the literature and discusses appropriate essential oil mixtures for use in women's health setting and labor and delivery.

Psychological distress after stroke and aphasia: the first six months.

OBJECTIVE: We explored the factors that predicted psychological distress in the first six months post stroke in a sample including people with aphasia. DESIGN: Prospective longitudinal observational study. SETTING AND SUBJECTS: Participants with a first stroke from two acute stroke units were assessed while still in hospital (baseline) and at three and six months post stroke. MAIN MEASURES: Distress was assessed with the General Health Questionnaire-12. Other measures included: NIH Stroke Scale, Barthel Index, Frenchay Aphasia Screening Test, Frenchay Activities Index, MOS Social Support Scale and social network indicators. Logistic regression was used to identify predictors of distress at each stage post stroke; and to determine what baseline factors predicted distress at six months. RESULTS: Eighty-seven participants were able to self-report on measures used, of whom 32 (37%) had aphasia. 71 (82%) were seen at six months, including 11 (16%) with aphasia. Predictors of distress were: stroke severity at baseline; low social support at three months; and loneliness and low satisfaction with social network at six months. The baseline factors that predicted distress at six months were psychological distress, loneliness and low satisfaction with social network (Nagelkerke R(2) = 0.49). Aphasia was not a predictor of distress at any time point. Yet, at three months post stroke 93% of those with aphasia experienced high distress, as opposed to 50% of those without aphasia (chi(2) (1) = 8.61, P<0.01). CONCLUSIONS: Factors contributing to distress after stroke vary across time. Loneliness and low satisfaction with one's social network are particularly important and contribute to long-term psychological distress.

Space re-exploration in hemispatial neglect.

Exploration of the space around us is a fundamental part of human behaviour. When it breaks down there is an important opportunity to understand its underlying mechanisms. Here we show that many right-hemisphere patients with left neglect re-explore rightward locations, failing to keep track of them during search. Importantly, such re-exploration occurred despite leftward stimuli being indistinguishable in peripheral vision, so it is unlikely to result from implicit processing of neglected targets. Revisits generally occurred after visits to other targets and are therefore not immediate perseverations. Finally, manipulating the visual salience of found targets altered the degree of neglect, but not revisit rates. Space exploration appears to be modulated both by the ability to keep track of spatial locations and by stimulus salience.
