Abstract
BACKGROUND Alcoholism associates with increased Staphylococcus aureus bacteremia incidence and mortality. The objective was to compare disease progression, treatment and prognosis of Staphylococcus aureus bacteremia in alcoholics versus non-alcoholics. METHODS The study design was a multicenter retrospective analysis of methicillin-sensitive Staphylococcus aureus bacteremia with 90-day follow-up. Patients were stratified as alcoholics or non-alcoholics based on electronic health record data. Altogether 617 Staphylococcus aureus bacteremia patients were included of which 83 (13%) were alcoholics. RESULTS Alcoholics, versus non-alcoholics, were younger, typically male and more commonly had community-acquired Staphylococcus aureus bacteremia. No differences in McCabe´s classification of underlying conditions was observed. Higher illness severity at blood culture sampling, including severe sepsis (25% vs. 7%) and intensive care unit admission (39% vs. 17%), was seen in alcoholics versus non-alcoholics. Clinical management, including infectious disease specialist (IDS) consultations and radiology, were provided equally. Alcoholics, versus non-alcoholics, had more pneumonia (49% vs. 35%) and fewer cases of endocarditis (7% vs. 16%). Mortality in alcoholics versus non-alcoholics was significantly higher at 14, 28 and 90 days (14% vs. 7%, 24% vs. 11% and 31% vs. 17%), respectively. Considering all prognostic parameters, male sex (OR 0.19, p = 0.021) and formal IDS consultation (OR 0.19, p = 0.029) were independent predictors of reduced mortality, whereas ultimately or rapidly fatal comorbidity in McCabe´s classification (OR 12.34, p < 0.001) was an independent predictor of mortality in alcoholics. CONCLUSIONS Alcoholism deteriorates Staphylococcus aureus bacteremia prognosis, and our results suggests that this is predominantly through illness severity at bacteremia onset. Three quarters of Staphylococcus aureus bacteremia patients we studied had identified deep infection foci, and of them alcoholics had significantly less endocarditis but nearly half of them had pneumonia.

Scand J Clin Lab Invest 2023; 83:432-438. [PMID: 37694716 DOI: 10.1080/00365513.2023.2255970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 08/18/2023] [Accepted: 09/03/2023] [Indexed: 09/12/2023]
Abstract
We set out to determine the performance of the Testi Technologies enzymatic assay saliva ethanol test strips of three different detection levels: 0 g/L, 0.2 g/L and 0.5 g/L, using as the reference method a gas chromatography analyser (GC). Alcohol levels were measured in 104 volunteers at up to three points in time, using up to three test strips per measurement, while gathering blood samples and breathalyser readings in parallel. The plasma alcohol concentrations (PAC) were determined from the plasma samples using GC. The qualitative results of the test strips were compared to the quantitative results from the reference method, as well as the breathalyser readings, and the amount of true and false positive and true and false negative results were classified using predetermined cut-off levels. The best performing test strips were the 0 g/L and the 0.2 g/L strips. The 0 g/L strips had a sensitivity and specificity of 1.00, as false negatives and false positives were not detected. The 0.2 g/L strips had a sensitivity and specificity [95% confidence interval (CI)] of 0.98 (0.96 - 1.00) and 0.83 (0.62 - 1.00) respectively, an accuracy of 0.97 (0.95 - 0.99), and a diagnostic odds ratio of 205.00 (35.33 - 1189.66). The test strips perform their intended purpose of screening for alcohol consumption well, with their great sensitivity as a defining property compared to other testing methods. For them to be able to be implemented in a clinical setting however, further refinement of the tests' characteristics would be required.

Abstract
BACKGROUND Ischemic stroke is the leading cause of disability and one of the leading causes of death. Ischemic stroke mimics (SMs) can account for a noteble number of diagnosed acute strokes and even can be thrombolyzed. METHODS The aim of our comprehensive review was to summarize the findings of different studies focusing on the prevalence, type, risk factors, presenting symptoms, and outcome of SMs in stroke/thrombolysis situations. RESULTS Overall, 61 studies were selected with 62.664 participants. Ischemic stroke mimic rate was 24.8% (15044/60703). Most common types included peripheral vestibular dysfunction in 23.2%, toxic/metabolic in 13.2%, seizure in 13%, functional disorder in 9.7% and migraine in 7.76%. Ischemic stroke mimic have less vascular risk factors, younger age, female predominance, lower (nearly normal) blood pressure, no or less severe symptoms compared to ischemic stroke patients (p < 0.05 in all cases). 61.7% of ischemic stroke patients were thrombolysed vs. 26.3% among SMs (p < 0.001). (p < 0.001). Overall intracranial hemorrhage was reported in 9.4% of stroke vs. 0.7% in SM patients (p < 0.001). Death occurred in 11.3% of stroke vs 1.9% of SM patients (p < 0.001). Excellent outcome was (mRS 0-1) was reported in 41.8% ischemic stroke patients vs. 68.9% SMs (p < 0.001). Apart from HINTS manouvre or Hoover sign there is no specific method in the identification of mimics. MRI DWI or perfusion imaging have a role in the setup of differential diagnosis, but merit further investigation. CONCLUSION Our article is among the first complex reviews focusing on ischemic stroke mimics. Although it underscores the safety of thrombolysis in this situation, but also draws attention to the need of patient evaluation by physicians experienced in the diagnosis of both ischemic stroke and SMs, especially in vertigo, headache, seizure and conversional disorders.

Abstract
PURPOSE The relationship between the telestroke technology and clinical risk factors in a dysplipidemic ischemic stroke population and neurologic outcomes is not fully understood. This issue was investigated in this study. PATIENTS AND METHODS We analyzed retrospective data collected from a regional stroke registry to identify demographic and clinical risk factors in patients with improving (NIHSS ≤ 7) or worsening (NIHSS > 7) neurologic outcome in dyslipidemic ischemic stroke population. We used logistic multivariate models to identify independent predictors of improving or worsening outcome based on dyslipidemia disease status in ischemic stroke patients. RESULTS In the adjusted analysis for dyslipidemic ischemic stroke population, cholesterol reducer use (odd ratio; [OR] = 0.393, 95% confidence interval [CI], 0.176-0.879, P = 0.023) and direct admission (OR = 0.435, 95% CI, 0.199-0.953, P = 0.037) were more likely to be associated with neurologic improvement and no clinical or demographic factors were associated with poor neurologic outcome in dyslipidemic ischemic stroke patients treated in the telestroke network. For the ischemic stroke population without dyslipidemia, increasing age (OR = 1.070, 95% CI, 1.031-1.109, P < 0.001), coronary artery disease (OR = 3.633, 95% CI, 1.307-10.099, P = 0.013), history of drug or alcohol abuse (OR = 6.548, 95% CI, 1.106-38.777, P = 0.038), and improvement in ambulatory outcome (OR = 2.880, 95% CI, 1.183-7.010, P = 0.020) were associated with worsening neurological functions, while being Caucasian (OR = 0.294, 95% CI, 0.098-0.882, P = 0.029) was associated with improving neurologic functions. CONCLUSION Demographic and clinical risk factors among the dysplipidemic ischemic stroke population in the telestroke network were not associated with worsening neurologic functions.

Abstract
Multiple sclerosis (MS) is an inflammatory demyelinating disorder characterized by the progressive disruption of the myelin sheath around the nerve fibres. The early initiation of disease-modifying treatments is crucial for preventing disease progression and neurological damage. Unfortunately, a diagnostic delay of several years is not uncommon, particularly in the presence of physical and mental comorbidities. Among psychiatric comorbidities, the role of alcohol misuse is still under debate. In this paper, we discuss a case of early-onset alcohol dependence and its possible role in delaying the initiation of a specific therapy for MS. The differential diagnosis between idiopathic and secondary neurodegenerative disorders is often challenging. When dealing with patients reporting an early-onset substance abuse (likely to present organic damage), clinicians may be prone to formulate a diagnosis of secondary neuropathy, particularly when facing non-specific symptoms. This case report highlights the need for in-depth medical investigations (including imaging) in the presence of neurological signs suggesting a damage of the central nervous system, prompting a differential diagnosis between idiopathic and secondary neurodegenerative conditions. Indeed, a timely diagnosis is crucial for the initiation of specific therapies positively affecting the outcome.

Introduction of an Electronic Mobile Device Version of an Alcohol Impairment Scale (the Hack's Impairment Index Score) Does Not Impair Nursing Assessment of Patients in Emergency Departments. Curr Ther Res Clin Exp 2021; 94:100630. [PMID: 34306270 PMCID: PMC8296087 DOI: 10.1016/j.curtheres.2021.100630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 03/19/2021] [Indexed: 11/28/2022] Open
Abstract
Annually, there are up to 5 million visits to EDs across the country of patients with a primary complaint of “Alcohol Intoxication”. ED Health Care Providers are charged with initial assessment, serial evaluations and then deciding when these patients are clinically improved to the point when they are ready for disposition. Previously, there was no widely accepted tool for providers to use to perform a standardized, formal examination of these patients. Hack's Impairment Index (HII Score) is a clinical tool currently being used at the bedside by nurses at select institutions across the United States using paper prompts. An App version of the HII Score for use on mobile devices was developed. This study evaluated the effects on nursing performance with the tool when paper charting was replaced.
Background There is no formal assessment to determine level of disability in the millions of patients with alcohol-induced impairment who present to emergency departments annually. Hack's Impairment Index (HII) is a standardized, serializable clinical tool designed to quantify ability. Nursing staff members at this center perform the HII and determine a score using paper prompts. Objective We developed an HII electronic application and investigated whether or not an electronic version on a mobile device would affect nursing performance. Methods A chart review-based quality improvement project compared the number, repetitions, and completeness of HII score documentation performed by nurses over 6.5 months. Group 1: paper-based HII scores for the 90-day period before intervention; group 2: iPad-based HII scores for the 90 days after intervention. There was a 2-week period for staff training and electronic version feedback between groups. Informal, ad hoc interviews were performed with nurses at investigation termination. Results Group 1: 476 emergency department patients with alcohol-induced impairment had HII scores ordered; 339 (71.2%; 95% CI, 67.1, 75.3%) had HII assessments with a total of 539 HII scores documented. An average (SD) 1.60 (0.01) serial assessments occurred per patient, 5 (1.1%; 95% CI, (0, 2.2%) scores were incomplete. Group 2: 569 alcohol-induced impairment emergency department patients were seen and had HII scores ordered; 420 (73.8%; 95% CI, (70.2, 77.4%) had HII assessments with a total of 639 HII scores documented. An average (SD) 1.52 (0.03) serial assessments occurred per patient, 4 (0.9%; 95% CI, (0.81, 0.99%) had incomplete HII scores. Conclusions Although our study took place at 1 center, was a chart review, and not directly observed, we found that the mobile device-based HII application to determine a score did not interfere with nursing performance. Specifically, the repetition and completeness of nursing assessments of emergency department patients with impairment from alcohol use was not altered when comparing paper chart documentation with electronic format documentation.

Abstract
Background Acute ischemic stroke attack with and without a recent TIA may differ in clinical risk factors, and this may affect treatment outcomes following thrombolytic therapy. We examined whether the odds of exclusion or inclusion for thrombolytic therapy are greater in ischemic stroke with TIA less than 24 h preceding ischemic stroke (recent-TIA) as compared to those without recent TIA or non-TIA > 24 h and less than 1 month (past-TIA). Methods A retrospective hospital-based analysis was conducted on 6315 ischemic stroke patients, of whom 846 had proven brain diffusion-weighted magnetic resonance imaging (DW-MRI) of an antecedent TIA within 24 h prior to ischemic stroke. The logistic regression model was developed to generate odds ratios (OR) to determine clinical factors that may increase the likelihood of exclusion or inclusion for thrombolytic therapy. The validity of the model was tested using a Hosmer-Lemeshow test, while the Receiver Operating Curve (ROC) was used to test the sensitivity of our model. Results In the recent-TIA ischemic stroke population, patients with a history of alcohol abuse (OR = 5.525, 95% CI, 1.003–30.434, p = 0.05), migraine (OR = 4.277, 95% CI, 1.095–16.703, p = 0.037), and increasing NIHSS score (OR = 1.156, 95% CI, 1.058–1.263, p = 0.001) were associated with the increasing odds of receiving rtPA, while older patients (OR = 0.965, 95% CI, 0.934–0.997, P = 0.033) were associated with the increasing odds of not receiving rtPA. Conclusion In recent-TIA ischemic stroke patients, older patients with higher INR values are associated with increasing odds of exclusion from thrombolytic therapy. Our findings demonstrate clinical risks factors that can be targeted to improve the use and eligibility for rtPA in in recent-TIA ischemic stroke patients.

Abstract
BACKGROUND AND AIM Alcohol intoxication can be a posterior circulation stroke mimic as they share symptoms such as dysarthria, gait disturbances and nystagmus. We describe alcohol intoxication as a stroke mimic and the frequency of acute alcohol intoxication among stroke patients. METHODS Prospective observational single-center study (2014-2017, Haga Ziekenhuis, the Hague). In all patients older than 16 years presenting as possible acute stroke less than 6 hours of onset, blood ethanol was measured; greater than 0.1 blood alcohol concentration (BAC) was considered elevated. RESULTS In total 974 patients were included: 60 (6%) had elevated blood ethanol (mean: 1.3 BAC). In 180 of 974 patients (18%) a stroke mimic was diagnosed: 12 were due to alcohol intoxication (1% of total cohort, 7% of stroke mimic, mean ethanol level: 2.2 BAC). Half of these patients denied or downplayed their alcohol consumption. Stroke and concurrent alcohol intoxication occurred in 38 of 794 strokes (5%, mean ethanol level: 1.1 BAC). Compared to other stroke patients, these 38 patients presented more often after working hours (mean 6.38pm versus 2.23pm) and received alteplase and endovascular therapy less often (24% versus 43%, P = .018 and 3% versus 10%, P = .241, respectively). CONCLUSIONS Of all patients presenting as possible acute stroke, 6% also drank alcohol. 18% of the whole cohort was diagnosed with a stroke mimic. Acute alcohol intoxication as sole diagnosis was diagnosed in 1% of the total cohort and 7% of stroke mimics, 50% denied or downplayed their alcohol consumption. 5% of all stroke patients also drank alcohol, they were significantly less likely to receive alteplase or endovascular treatment.
