A Case-Control Study of Distinguishing Between Stroke Mimics and True Strokes.

This study was conducted with the primary aim to distinguish patients with a true stroke versus a stroke mimic based on clinical features and imaging. We conducted a retrospective case-control study on 116 adult patients who received alteplase (tPA) to treat acute stroke at our hospital. We further analyzed 79 patients with a normal computed tomography angiography (CTA). Based on their magnetic resonance imaging (MRI) of the brain, they were divided into cases (stroke mimics) and controls (true strokes). Data were collected retrospectively by reviewing individual medical charts on the electronic medical record (EMR), including age, gender, history of stroke, seizure, hypertension, diabetes, atrial fibrillation, hyperlipidemia, presenting NIH Stroke Scale/Score, hemorrhagic conversion, history of migraine, history of depression, sidedness of symptoms and aphasia. Data were categorized to separate those who were later diagnosed to be stroke mimics by being-postictal, encephalopathic, in acute migraine, suffered post-stroke recrudescence (PSR) due to metabolic insult, or had conversion disorder when symptoms could not be attributed to any medical condition or mental illness. Of the 79 study subjects, 48 (60%) were stroke mimics. The mean age of the cohort was 68.67 years, and 46.8% of the study subjects were females. Based on the multivariate logistic regression analysis, factors associated with being a stroke mimic were older age, history of migraine, and a history of prior stroke. In conclusion, increased attention to history and clinical examination as the first step can aid in the proper diagnosis of strokes versus stroke mimics. Identifying stroke mimics early could help expedite hospital workup and prevent inadvertent investigations, reducing hospital occupancy during the ongoing COVID-19 pandemic. We could potentially avoid the administration of tPA to such patients, reducing both the cost and adverse effects of it. Every stroke can cause neurological deficits, but every deficit need not be a stroke.

Harms and Contributors of Leaving Against Medical Advice in Patients With Infective Endocarditis.

INTRODUCTION: Patients leaving against medical advice (AMA) are commonly encountered in hospital medicine. The problem is prevalent worldwide and across all fields of medicine. A retrospective study of 47,583 patients reported a 3.3% AMA rate in 2015. OBJECTIVES: In this retrospective study, we aimed (1) to study the demographic, clinical, and laboratory parameters of infective endocarditis (IE) patients leaving AMA. We also compared (2) the various risk factors and outcomes of these patients with IE patients who completed treatment. RESULTS: A total of 111 patients diagnosed with IE were recruited for 36 months. Of the 74 patients with available details, 32 patients (29%) left AMA during their treatment. The mean age of patients leaving AMA was 39, and among those who left AMA, 66% were females. As compared with patients completing therapy, patients leaving AMA tend to have higher comorbidities, including injection drug use (68.1% versus 31.9%), prior IE (83.3% versus 16.7%), and chronic hepatitis C (72.4% versus 27.8%). Rates of consumption of substances of abuse were higher among those who left AMA. Patients leaving AMA also had higher psychiatric comorbidities (63% versus 37.5%), history of leaving AMA (70.5% versus 29.5%), and consumption of more than 2 substances of abuse. Morbidity was higher in patients leaving AMA. There was a statistically significant association between the development of distal embolus ( P < 0.001), the need for recurrent admissions ( P = 0.002), recurrent bacteremia ( P < 0.001), developing new embolus ( P < 0.001), and overall morbidity ( P = 0.002) among IE patients leaving AMA. CONCLUSIONS: Infective endocarditis patients leaving AMA tend to be younger females. These patients have prior comorbidities of injection drug use, prior IE, multiple psychiatric comorbidities, drug use, and multiple socioeconomic issues. Patients leaving AMA tend to develop further non-Central nervous system embolic events, recurrent bacteremia, and require frequent admissions. Morbidity in these patients was higher.

Predictors, patterns and outcomes following Infective endocarditis and stroke.

Patients with infective endocarditis can have multiple neurological manifestations.  Cerebrovascular events (CVE) in patients with IE can be hemorrhagic or embolic.  Multiple factors are known to predispose to CVE and increased mortality in patients with IE.  In this study, we aimed to describe various outcomes among patients with IE and CVE.  We retrospectively analyzed 160 patients with definite IE.  Among these, patients with radiological evidence of CVE were included.  Clinical, radiological, echocardiographic details were obtained.  Outcome studied were the requirement of intensive care unit care, the requirement of mechanical ventilation, prolonged course of antibiotics, prolonged duration of hospital stay, the requirement of surgical intervention, and mortality.  In this study, 16 [10%] of patients with IE were identified to have a CVE.  The mean age of the patients was 55, and 87.5% of them were male.  25% of patients had prior IE.  IE involving left-sided valves were predominant, with the involvement of mitral valve reported in 62.5% of patients.  More than half of the patient's had details of magnetic resonance imaging (MRI) of the brain.  CVE were mostly ischemic, anterior circulation predominant, multiple, and bilateral.  In patients with IE and CVE morbidity including the requirement of ICU care, prolonged antibiotics course, and the requirement of surgical intervention contributed to increased duration of hospital stay.  In conclusion, CVE in patients with IE tends to present as multiple infarcts predominantly located over anterior circulation.  IE patients with CVE tend to have higher morbidity and mortality.

To study the contributing factors and outcomes of Clostridioides difficile infection in patients with solid tumors.

BACKGROUND: Clostridioides difficile infection (CDI) is a considerable healthcare burden, and now identified as the leading cause of acquired diarrheal illness in patients receiving antibiotics. Patients with malignancies are more prone to acquire CDI, owing to their frequent exposure to risk factors. OBJECTIVE: This study aims to investigate the factors affecting the outcome of Clostridioides Difficile Infection in patients with solid tumors at our community healthcare center. METHODS: This is a retrospective study that included a total of 59 patients with solid tumors who were hospitalized for Clostridioides difficile infection. RESULTS: The median age of the study population was 79 years with 39 males and 20 females. The patients had a diagnosis of a malignancy involving the following sites: prostate (25), lung (19), colon (7), bladder (4), breast (3), and renal (1). There were 52 cases of first time and 7 cases of recurrent CDI admissions. 40 patients were detected to have CDI at presentation while 19 patients were diagnosed with CDI after admission. CDI was categorized as follows: non-severe (29), severe (28), and very severe (2). There were 33 patients on chemotherapy and 20 patients undergoing radiotherapy. Twenty-seven patients had a recent history of cancer care-related procedures or interventions. Twenty-nine patients were from either a rehabilitation center or a long-term nursing care facility. There were 39 recent hospitalizations with 29 patients receiving antibiotics. Almost half of the patients were on proton pump inhibitors (29) and 12 were on steroids (20.3%) at the time of developing CDI. Patients with a high-risk qSOFA score of 2 or more (p-value = 0.008) or a high white blood cell count of >15 × 109/L (p-value = 0.016) at the time of admission were found to have higher in-hospital mortality. Critical care data suggested that 9 patients required intensive care, 7 patients required vasopressor support, and 6 needed mechanical ventilation. Patients were treated with either vancomycin alone (13), or metronidazole alone (25), or combination therapy with vancomycin + metronidazole (21). The median duration of hospital stay was 6 days with 11 fatalities (18.64%). CONCLUSIONS: CDI causes significant morbidity in patients with malignancies. A high qSOFA score and leukocytosis are significantly associated with high morbidity and thus should be used to prioritize and intensify inpatient care of these patients.

Factors contributing to poor outcome in patients on warfarin receiving 4-factor prothrombin complex concentrate in critically ill.

AIM: To compare the demographical profile, indications, efficacy, and contributors to adverse outcome following administration of 4F-PCC in patients on warfarin with supratherapeutic INR. METHODOLOGY: Retrospective cross-sectional study was performed in a community based teaching hospital. All patients 18 years and older on warfarin with supratherapeutic INR, who had received 4F-PCC between January 2014 and December 2018 were eligible and included in the study. RESULTS: 44 patients were included in the analysis. The mean age of the patients was 79.5 years. The male to female ratio was 1:1. Patients were on warfarin for atrial fibrillation, thromboembolism in 79.5% (N-35), and 20.5% (N-9) respectively. Indications for use of 4F-PCC were active bleeding in 93% (N-41) of patients. The common sites of bleeding were gastrointestinal, intracranial, and musculoskeletal which were seen in 54.5% (N-24), 29.5% (N-13) and 6.8% (N-3) respectively. The median number of doses of 4F-PCC administered was 1 per patient. The mean dose administered was 2,883u. Clinical improvement was documented in 84% (N-37) of patients. Mortality was seen in 16% (N-7) of patients. BMI greater than 30, anemia, hypotension, presence of intracranial bleed, the requirement of blood products, and mechanical ventilation were associated with higher odds for mortality. Hypotension and requirement of mechanical ventilation were statistically significant. CONCLUSION: 4F-PCC continues to be an effective agent in the rapid reversal of warfarin therapy in patients with supratherapeutic INR presenting with major bleeding events. Most patients have clinical improvement with a single, weight-adjusted dose.

Systematic Review of Methemoglobinemia in Acetaminophen Poisoning.

BACKGROUND: Acetaminophen (N-acetyl-para-aminophenol, paracetamol, (APAP) toxicity is one of the commonly encountered poisonings by emergency physicians. Methemoglobinemia is an uncommon association and rarely seen in APAP poisoning. METHODS: Retrospective analysis of all the published reports on APAP induced methemoglobinemia from 1968 to 2019. RESULTS: In total there were 14 cases with 9 females and 6 males. The median age of the study cohort was 59 years. The most common presenting feature was altered mentation (9 patients) followed by cyanosis (3 patients). The intent of consumption was therapeutic (7 cases) versus suicidal (5 cases) attempt.In most cases, the dose of APAP consumption was not known. Aspirin, sulfasalazine, benzocaine spray, nitrate preservative, contaminated water, detergents, etc. where the other agents consumed by the patients in addition to APAP before developing methemoglobinemia. The median MethHb level of the study cohort was 15.85% Patients were treated with NAC, hemodialysis, methylene blue, and ascorbic acid and CRRT in various combinations. Full recovery was seen in 9 patients while 4 patients died. CONCLUSION: APAP toxicity is a well-known and common entity with multiple sequelae that presents with a variable spectrum of mild to fulminant multiorgan failure. Awareness of non-classical presentations like methemoglobinemia is essential to ensure timely intervention.

Clinical spectrum, risk factors, management and outcome of patients with retroperitoneal hematoma: a retrospective analysis of 3-year experience.

Objective: Retroperitoneal Hematoma (RPH) is an underdiagnosed and overlooked disease entity and has a high mortality rate if not diagnosed in a timely manner. This study aims to analyze the clinical characteristics, risk factors, treatment and the outcome of RPH cases at our medical center.Methods: In this retrospective study, all cases who presented to the emergency room (ER) and/or admitted to our center with the diagnosis of RPH from Jan 2016 to Dec 2018 were included (3-year data).Results: A total number of 78 RPH cases were included including both the traumatic and spontaneous bleed. The most common setting was spontaneous bleeding with no concurrent use of anti-thrombotic agents. Zone 3 (pelvic hematoma) bleed was the most common type of RPH. Most patients were successfully managed medically alone (59%). Others required surgical intervention, either laparoscopy, laparotomy or through the interventional radiological approach. There was a significant association between the need for vasopressors (OR-5.65, P-value of 0.039), spontaneous bleed (P-value of 0.001), bleed without antithrombotic agents (P-value of 0.002) with prolonged hospital stay (> 5 days). On follow-up, 83% of cases were reported to be alive. Only 2 patients died secondary to hemorrhagic shock.Conclusion: Most cases of RPH had an excellent outcome with conservative management alone.

Factors Associated with 30-day Unplanned Readmissions of Sepsis Patients: A Retrospective Analysis of Patients Admitted with Sepsis at a Community Hospital.

Introduction Mortality from sepsis is decreasing in recent years owing to improved quality of care, targeted programs, and the implementation of sepsis bundles. This has led to an increased pool of sepsis survivors at risk of readmissions. Studies have shown that these sepsis readmissions are common and expensive. The factors associated with these readmissions remain elusive and have incited a lot of research in recent years. The 30-day sepsis readmission rate is increasingly being used as a quality metric for hospitals. A conducted a retrospective chart review analysis of patients admitted with sepsis to find factors affecting the 30-day readmissions of sepsis survivors. Methods Patients admitted to our hospital either on the medical-surgical floor or in the intensive care unit (ICU) with an administrative coding for sepsis between January 2014 to November 2015 were identified. A literature search, as well as expert opinion, was considered for the list of factors to be studied, including age, sex, residence on admission, length of stay, getting hemodialysis, hospitalization in the prior year, presence of acute kidney injury (AKI), source of sepsis, discharge disposition, receipt of red blood cell (RBC) products, and route of antibiotics on discharge. A univariate binary logistic regression analysis was performed to test the association between the above-mentioned variables and sepsis readmission. Variables with statistical significance in the univariate analysis were used to compute the multivariate regression analysis along, with adjusted OR and their 95% CI. Results A total of 1297 patients were identified with sepsis. Of these, 1068 patients met inclusion criteria. The readmission rate in our study population was 19.19%, and 52% of the readmissions were secondary to an infectious cause. After controlling for the effect of all the potential confounders, the factors that showed a positive association with readmissions were hospitalizations in the year prior to the index hospitalization and discharge to either nursing home or short-term rehab. The requirement of the intensive care unit was not associated with increased readmission. High hemoglobin on discharge was associated with a reduced chance of readmission. Conclusions Readmissions after sepsis hospitalization are common and mostly caused by infections. Several factors associated with index sepsis hospitalization can be associated with readmissions. Some of these factors are modifiable and more research is needed to see if these readmissions can be prevented.
