Oral Fluid, Electrolytes, and Energy Management in Various Adult and Geriatric Illnesses beyond Diarrhea: An Indian Expert Panel Delphi Consensus Recommendation.

BACKGROUND: Dehydration is a highly prevalent clinical challenge in adults which can go undetected. Although dehydration is commonly associated with an increased risk of hospitalization and mortality, only a few international guidelines provide recommendations regarding oral fluids, electrolytes, and energy (FEE) management in adults/geriatrics with dehydration due to nondiarrheal causes. Currently, there is a lack of comprehensive recommendations on the role of oral FEE in nondiarrheal dehydration in adult and geriatric Indian patients. MATERIALS AND METHODS: A modified Delphi approach was designed using an online questionnaire-based survey followed by a virtual meeting, and another round of online surveys was used to develop this consensus recommendation. In round one, 130 statements, including 21 open-ended questions, were circulated among ten national experts who were asked to either strongly agree, agree, disagree, or strongly disagree with statements and provide responses to open-ended questions. The consensus was predefined at 75% agreement (pooling "strongly agree" and "agree" responses). Presentation of relevant literature was done during a virtual discussion, and some statements (the ones that did not achieve predefined agreement) were actively discussed and deliberately debated to arrive at conclusive statements. Those statements that did not reach consensus were revised and recirculated during round two. RESULTS: Consensus was achieved for 130/130 statements covering various domains such as assessment of dehydration, dehydration in geriatrics, energy requirement, impact of oral FEE on patient outcome, and fluid recommendations in acute and chronic nondiarrheal illness. However, one statement was not added as a recommendation in the final consensus (129/130) as further literature review did not find any supporting data. Oral FEE should be recommended as part of core treatment from day 1 of acute nondiarrheal illness and started at the earliest feasibility in chronic illnesses for improved patient outcomes. Appropriately formulated fluids with known electrolyte and energy content, quality standards, and improved palatability may further impact patient compliance and could be a good option. CONCLUSION: These consensus recommendations provide guidance for oral FEE recommendations in Indian adult/geriatric patients with various nondiarrheal illnesses.

Recommendations for Evaluation and Selection of Deceased Organ Donor: Position Statement of ISCCM.

There is a wide gap between patients who need transplants and the organs that are available in India. Extending the standard donation criterion is certainly important to address the scarcity of organs for transplantation. Intensivists play a major role in the success of deceased donor organ transplants. Recommendations for deceased donor organ evaluation are not discussed in most intensive care guidelines. The purpose of this position statement is to establish current evidence-based recommendations for multiprofessional critical care staff in the evaluation, assessment, and selection of potential organ donors. These recommendations will give "real-world" criteria that are acceptable in the Indian context. The aim of this set of recommendations is to both increase the number and enhance the quality of transplantable organs.

Renal Replacement Therapy in Adult Intensive Care Unit: An ISCCM Expert Panel Practice Recommendation.

Acute kidney injury (AKI) contributes significantly to morbidity and mortality in ICU patients. The cause of AKI may be multifactorial and the management strategies focus primarily on the prevention of AKI along with optimization of hemodynamics. However, those who do not respond to medical management may require renal replacement therapy (RRT). The various options include intermittent and continuous therapies. Continuous therapy is preferred in hemodynamically unstable patients requiring moderate to high dose vasoactive drugs. A multidisciplinary approach is advocated in the management of critically ill patients with multi-organ dysfunction in ICU. However, an intensivist is a primary physician involved in life-saving interventions and key decisions. This RRT practice recommendation has been made after appropriate discussion with intensivists and nephrologists representing diversified critical care practices in Indian ICUs. The basic aim of this document is to optimize renal replacement practices (initiation and management) with the help of trained intensivists in the management of AKI patients effectively and promptly. The recommendations represent opinions and practice patterns and are not based solely on evidence or a systematic literature review. However, various existing guidelines and literature have been reviewed to support the recommendations. A trained intensivist must be involved in the management of AKI patients in ICU at all levels of care, including identifying a patient requiring RRT, writing a prescription and its modification as per the patient's metabolic need, and discontinuation of therapy on renal recovery. Nevertheless, the involvement of the nephrology team in AKI management is paramount. Appropriate documentation is strongly recommended not only to ensure quality assurance but also to help future research as well.

ISCCM Guidelines on Acute Kidney Injury and Renal Replacement Therapy.

Acute kidney injury (AKI) is a complex syndrome with a high incidence and considerable morbidity in critically ill patients. Renal replacement therapy (RRT) remains the mainstay of treatment for AKI. There are at present multiple disparities in uniform definition, diagnosis, and prevention of AKI and timing of initiation, mode, optimal dose, and discontinuation of RRT that need to be addressed. The Indian Society of Critical Care Medicine (ISCCM) AKI and RRT guidelines aim to address the clinical issues pertaining to AKI and practices to be followed for RRT, which will aid the clinicians in their day-to-day management of ICU patients with AKI.

Automated Continuous Electrocardiogram Monitoring Accelerates the Detection of Atrial Fibrillation after Ischemic Stroke or Transient Ischemic Attack on a Hyper Acute Stroke Unit.

BACKGROUND AND AIM: Rapid and sensitive detection of atrial fibrillation (AF) is of paramount importance for initiation of adequate preventive therapy after stroke. Stroke Unit care includes continuous electrocardiogram monitoring (CEM) but the optimal exploitation of the recorded ECG traces is controversial. In this retrospective single-center study, we investigated whether an automated analysis of continuous electrocardiogram monitoring (ACEM), based on a software algorithm, accelerates the detection of AF in patients admitted to our Stroke Unit compared to the routine CEM. METHODS: Patients with acute ischemic stroke or transient ischemic attack were consecutively enrolled. After a 12-channel ECG on admission, all patients received CEM. Additionally, in the second phase of the study the CEM traces of the patients underwent ACEM analysis using a software algorithm for AF detection. Patients with history of AF or with AF on the admission ECG were excluded. RESULTS: The CEM (n = 208) and ACEM cohorts (n= 114) did not differ significantly regarding risk factors, duration of monitoring and length of admission. We found a higher rate of newly-detected AF in the ACEM cohort compared to the CEM cohort (15.8% versus 10.1%, P < .001). Median time to first detection of AF was shorter in the ACEM compared to the CEM cohort [10 hours (IQR 0-23) versus 46.50 hours (IQR 0-108.25), P < .001]. CONCLUSIONS: ACEM accelerates the detection of AF in patients with stroke compared with the routine CEM. Further evidences are required to confirm the increased rate of AF detected using ACEM.

Airway Management and Related Procedures in Critically Ill COVID-19 Patients: Position Statement of the Indian Society of Critical Care Medicine.

The coronavirus disease (COVID-19) pandemic has affected nearly all nations globally. The highly contagious nature of the disease puts the healthcare workers at high risk of acquiring infection, especially while handling airway and performing aerosol-generating procedures. The Indian Society of Critical Care Medicine, through this position paper, aims to provide guidance for safe airway management to all healthcare workers dealing with airway in COVID-19 patients.

Critical Care for COVID-19 Affected Patients: Updated Position Statement of the Indian Society of Critical Care Medicine.

The management of coronavirus disease-2019 (COVID-19) is witnessing a change as we learn more about the pathophysiology and the severity of the disease. Several randomized controlled trials (RCTs) and meta-analysis have been published over the last few months. Several interventions and therapies which showed promise in the initial days of the pandemic have subsequently failed to show benefit in well-designed trials. Understanding of the methods of oxygen delivery and ventilation have also evolved over the past few months. The Indian Society of Critical Care Medicine (ISCCM) has reviewed the evidence that has emerged since the publication of its position statement in May and has put together an addendum of updated evidence.

Severe Hemorrhagic Transformation after Thrombolysis for Acute Ischemic Stroke Prevents Early Neurological Improvement.

BACKGROUND: Intravenous thrombolysis can improve neurological outcomes after acute ischemic stroke (AIS), but hemorrhagic transformation (HT) of the infarct remains a risk. Current definitions for symptomatic intracerebral hemorrhage (ICH) all entail that there be some degree of associated neurological deterioration. However, early deleterious effects of secondary ICH might also be manifested as reduced neurological improvement. This study aims to investigate whether there are any independent associations between different radiological subtypes of HT and the degree of neurological improvement 24 hours after thrombolysis. METHODS: This study is a retrospective analysis of a single-center database of consecutive thrombolysis cases for AIS. Multivariate regression analysis was undertaken to explore the relationship between different subtypes of HT with changes in National Institutes of Health Stroke Scale (NIHSS) score 24 hours after thrombolysis, after adjusting for potential confounders. RESULTS: As compared to cases with no HT, occurrence of the parenchymal hematoma 2 (PH2) subtype of secondary ICH was independently associated with reduced improvement or worsening in the NIHSS score, with an average effect size of 7 points (95% confidence interval -10 to -4, P < .001). In the absence of PH2, thrombolysis for AIS was generally associated with an improvement in the neurological status at 24 hours. CONCLUSIONS: The PH2 subtype of HT is associated with reduced neurological improvement or deterioration 24 hours after thrombolysis for AIS.

A Retrospective Cohort Study on the Use of Intravenous Thrombolysis in Stroke Mimics.

BACKGROUND: The urgency of intravenous thrombolysis in acute ischemic stroke can lead to inadvertent thrombolysis of patients with nonstroke diagnoses (stroke mimics), increasing the risk of adverse events. The objectives of this study were to compare thrombolysed acute ischemic stroke and stroke mimic cases based on demographic factors, physiological parameters, radiological findings, and clinical presentation, and to evaluate the clinical implications of thrombolysing stroke mimics. METHODS: A retrospective analysis of a single-center database of all thrombolysed strokes and mimics over a period greater than 3 years. Diagnoses were confirmed by expert consensus after a review of clinical factors and imaging. Intercohort variation was assessed using Wilcoxon rank-sum or Pearson's chi-square test. RESULTS: The stroke mimic cohort tended to be younger (mean age 59.9 years versus 73.7 years, P < .001) and had a lower National Institutes of Health Stroke Score at presentation (mean 5.9 points versus 6.4 points, P < .01). However, the time taken from the onset of symptoms to delivery of thrombolytic drugs was longer in the mimic cohort (mean time 170 minutes versus 138 minutes, P < .01). Any differences in blood glucose (P = .07), time taken from hospital arrival to delivery of intravenous thrombolysis (P = .57), and blood pressure on admission (systolic, P = .09 and diastolic, P = .34) were not statistically significant. No adverse events were reported in the mimic cohort. CONCLUSION: Despite similarities in clinical presentation, thrombolysed stroke mimics are of a different physiological and demographic population, and are associated with fewer adverse events compared with thrombolysed acute ischemic stroke patients.

Trends in C-Reactive Protein Levels Are Associated with Neurological Change Twenty-Four Hours after Thrombolysis for Acute Ischemic Stroke.

BACKGROUND: Elevated inflammatory markers such as C-reactive protein (CRP) are associated with worse outcomes in patients thrombolysed for acute ischemic stroke (AIS). AIMS: To investigate whether changes in CRP levels are associated with neurological change after thrombolysis for AIS. METHODS: Retrospective analysis of a single-center database of consecutive thrombolysis cases for AIS from October 18, 2011, to June 15, 2015, inclusive. Multivariate regression analysis was used to investigate the relationship between change in CRP 12-24 hours after thrombolysis and change in NIHSS (National Institutes of Health Stroke Scale) score 24 hours after thrombolysis. The other potentially confounding predictor variables included in the model were CRP on admission and NIHSS score before thrombolysis. RESULTS: Complete data were available for 108 out of possible 435 eligible patients. Increases in CRP levels 12-24 hours after thrombolysis were negatively associated with reduction in NIHSS score 24 hours after thrombolysis (coefficient .08, 95% confidence interval .031-.129, P = .002). Thus, on average, for every 12.5 mg/L additional increase in CRP 12-24 hours after thrombolysis, NIHSS score at 24 hours improved by 1 point less. CONCLUSION: While it was previously known that elevated CRP levels are associated with worse outcomes in patients thrombolysed for AIS, the current work demonstrates that changes in CRP levels after thrombolysis also relate to neurological change, and thus may have scope for use as prognostic markers.

A Fall in Systolic Blood Pressure 24 Hours after Thrombolysis for Acute Ischemic Stroke Is Associated with Early Neurological Recovery.

BACKGROUND: Outcomes are worse in patients who underwent thrombolysis for acute ischemic stroke (AIS) with persistent hypertension. The objective of this study is to investigate whether fall in systolic blood pressure (SBP) has any relationship with neurological outcome 24 hours after thrombolysis, after adjusting for potentially confounding factors. METHODS: Retrospective analysis of a single-center database of consecutive thrombolysis cases for AIS. Multivariate regression analysis was used to explore the relationship between fall in SBP and reduction in National Institutes of Health Stroke Scale (NIHSS) score 24 hours after thrombolysis. Other potentially confounding predictor variables used in the model were SBP on thrombolysis, blood glucose level on thrombolysis, NIHSS score on thrombolysis, administration of antihypertensive medications, and the time to thrombolysis after symptom onset. RESULTS: A fall in SBP 24 hours after thrombolysis is independently associated with greater improvement in NIHSS score 24 hours after thrombolysis (coefficient .051, 95% confidence interval .023-.078, P < .001). Thus, a reduction of 10 mmHg in SBP after 24 hours is associated with a .51 point reduction in the NIHSS score. CONCLUSIONS: Restoration of SBP toward normal limits after thrombolysis for AIS is associated with greater early neurological improvement.

Cerebellar Hemorrhage Presenting with Ventricular Tachycardia.

OBJECTIVE: The aim of the present study was to demonstrate the practical implications of the association between stroke and cardiac arrhythmia. METHODS: We present here a case of cerebellar hemorrhage presenting with nonsustained ventricular tachycardia (NSVT) in a 61-year-old man with no previously known medical problems. RESULTS: The patient was given oral metoprolol, with a significant reduction in the episodes of NSVT. On further examination, there was an ataxic gait and slurred speech, which was reported to be new by the patient and his accompanying partner. A computed tomography scan of the head performed within 3 hours of symptom onset demonstrated an acute cerebellar parenchymal hemorrhage with local mass effect and extension into the fourth ventricle. CONCLUSION: This case acts as a reminder of the association between stroke and cardiac arrhythmia. It is plausible that episodes of NSVT occurred before presentation and were exacerbated by the increased sympathetic activity following the onset of hemorrhage. As such, it is crucial to interpret electrocardiogram investigations in the context of the clinical presentation. Prompt diagnosis is vital to optimizing care.

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.

Culture-positive unilateral panophthalmitis in a serology-positive case of dengue hemorrhagic fever.

Dengue fever, a mosquito-borne disease commonly found in the tropics, is one of the most prevalent forms of Flavivirus infection in humans. Symptomatically, it is characterized by fever, arthralgia, headache, and rash. Ophthalmic manifestations can involve both the anterior and posterior segment. Panophthalmitis is rare in dengue hemorrhagic fever, and there is no report of culture-positive panophthalmitis in this setting. Here, we report a case of a serology-positive 33-year-old male patient of dengue hemorrhagic fever who developed sudden onset pain, redness, and proptosis in the right eye. The patient subsequently developed panophthalmitis in his right eye, and Bacillus cereus was isolated from eviscerated sample. This case provides unique insights into pathogenesis of panophthalmitis in dengue and highlights the management options.

Written medical discharge communication from an acute stroke service: a project to improve content through development of a structured stroke-specific template.

Specific guidelines for the content of discharge summaries from acute stroke services do not currently exist. The aims of this project were to assess the strengths and weaknesses of stroke discharge communication from Imperial College Healthcare NHS Trust, to develop a structured template to guide completion, and to re-audit discharge communication following its implementation. The audit compared local performance against record standards from the Academy of Medical Royal Colleges (1), which was augmented by criteria generated from the British Association of Stroke Physicians (BASP) Stroke Service Standards (2). Discharge information was examined within the Trust's Electronic Discharge Communication (EDC) system to determine the recording of selected items for consecutively discharged patients from the hyperacute and acute stroke units. The audit was repeated following implementation of a newly developed stroke-specific discharge summary template. Fifty-one EDC summaries were examined at baseline (July 2012) and 30 summaries at re-audit (January 2013). The criteria which showed low adherence initially and which showed the most significant improvement following the introduction of the template were the guidance on blood pressure and lipids targets (increased from 2% and 0% respectively at baseline, to 93% post intervention), and the driving and flying advice (from 3% to 79%). Documentation was also seen to improve for measures of physical and cognitive function, discharge arrangements, and follow up plans. This audit cycle has demonstrated improvement in the consistency of content within written discharge communication following the introduction of a structured stroke-specific template adhering to combined criteria from identified standards.

A Gabor-block-based kernel discriminative common vector approach using cosine kernels for human face recognition.

In this paper a nonlinear Gabor Wavelet Transform (GWT) discriminant feature extraction approach for enhanced face recognition is proposed. Firstly, the low-energized blocks from Gabor wavelet transformed images are extracted. Secondly, the nonlinear discriminating features are analyzed and extracted from the selected low-energized blocks by the generalized Kernel Discriminative Common Vector (KDCV) method. The KDCV method is extended to include cosine kernel function in the discriminating method. The KDCV with the cosine kernels is then applied on the extracted low-energized discriminating feature vectors to obtain the real component of a complex quantity for face recognition. In order to derive positive kernel discriminative vectors, we apply only those kernel discriminative eigenvectors that are associated with nonzero eigenvalues. The feasibility of the low-energized Gabor-block-based generalized KDCV method with cosine kernel function models has been successfully tested for classification using the L(1), L(2) distance measures; and the cosine similarity measure on both frontal and pose-angled face recognition. Experimental results on the FRAV2D and the FERET database demonstrate the effectiveness of this new approach.
