Incidence of Acute Ischemic Stroke in Hospitalized Patients With Atrial Fibrillation Who Had Anticoagulation Interruption: A Retrospective Study.

BACKGROUND: Atrial fibrillation (AF) is one of the leading causes of acute ischemic stroke requiring anticoagulation. Many patients experience treatment interruption in the hospital setting. The aim of this study was to evaluate the effect of anticoagulation interruption on short-term risk of ischemic stroke in hospitalized patients with AF. METHODS: We performed a retrospective medical record review using the Hospital Corporation of America (HCA) database. We included patients admitted to our institution between December 2015 and December 2018 who had a prior history of AF. Patients were excluded if they had ischemic stroke, hemorrhagic stroke, history venous thromboembolism or mechanical valve on admission. We compared the incidence of ischemic stroke in patients in whom anticoagulation was interrupted for more than 48 h to those who continued anticoagulation. RESULTS: A total of 2,277 patients with history of AF were included in the study. In this cohort, 79 patients (3.47%) had anticoagulation interruption of more than 48 h during their hospital stay. There was no difference in incidence of stroke between the interruption and no interruption groups (1.27% (n = 1) vs. 0.23% (n = 5), P = 0.19). Interruption of anticoagulation did not associate with a significant increase in the risk of in-hospital ischemic stroke. CHA2DS2VASc score was a strong predictor of in-hospital stroke risk regardless of anticoagulation interruption (odds ratio: 7.199, 95% confidence interval: 2.920 - 17.751). CONCLUSION: In this study, the in-hospital incidence of ischemic stroke in patients with AF did not significantly increase by short-term anticoagulation interruption.

Characteristics and outcomes of diabetic patients with acute exacerbation of COPD.

RATIONALE AIMS AND OBJECTIVES: Patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and diabetes mellitus form a special population due to an increased risk of hyperglycemia from the use of corticosteroids. There is limited data regarding specific outcomes in diabetic patients with AECOPD. METHODS: A retrospective data analysis of adult patients admitted to North Florida Division of the Hospital Corporation of America (HCA Healthcare) with a primary or secondary diagnosis of AECOPD from January 1, 2018, to December 31, 2018. We excluded patients who needed intensive care unit (ICU) care on day 0. Outcomes assessed included length of stay, mortality, and need for ICU transfer after 48 h from admission. Characteristics included age, sex, and race, comorbidities such as diabetes mellitus, chronic kidney disease, acute kidney injury, congestive heart failure, and anemia were analyzed. Comparisons were analyzed via binary and multivariate logistic regression models. RESULTS: A total of 3788 patients admitted for AECOPD were included; amongst them, 1356 patients (~36%) had diabetes mellitus. This subset of patients had higher rates of comorbidities. A significant portion of diabetic patients (72%) received intravenous rather than oral steroids, similar to non-diabetic patients. In addition, diabetic patients were more likely to develop acute kidney injury (14.2% vs 8.0%, p < 0.004) and decompensated heart failure (9.2% vs 4.6%, p < 0.001). Diabetic patients had higher length of stay and increased need for ICU transfer. However, diabetes itself did not independently affect length of stay (CI -0.028, 0.479, p = 0.081) when adjusted to comorbidities and patient's characteristics. Moreover, diabetes was independently associated with an increased need for transfer to ICU (Odds ratio 1.9, p = 0.031). The oral route of steroid use was associated with decreased LOS (ß coefficient - 0.9, p < 0.001). CONCLUSION: Diabetes mellitus is independently associated with increased ICU transfers amongst patients hospitalized with AECOPD. The use of oral steroids rather than intravenous steroids was independently associated with decreased length of stay in diabetic and non-diabetic patients. Despite no difference in intravenous vs. oral corticosteroids demonstrated in previous COPD trials, a significant portion of diabetic patients continue to receive intravenous corticosteroids. Further investigation is required to explore these findings.

Renin-Angiotensin-Aldosterone System Blockers Prior to Hospitalization and Their Association With Clinical Outcomes in Coronavirus Disease 2019 (COVID-19).

OBJECTIVE: To determine the effect of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) use prior to hospitalization on clinical outcomes in coronavirus disease 2019 (COVID-19) patients. DESIGN: An observational retrospective cohort study from 178 hospitals from a large health system across the United States.  Patient population: Hospitalized patients (n=2726) with confirmed COVID-19 between January 1, 2020, and April 1, 2020. Main outcome(s) and measure(s): Outcomes during hospitalization, including disease severity by level of care, intensive care unit (ICU) admission, mechanical ventilator (MV) use, hospital length of stay, and in-hospital death. Patient demographics and comorbidities were also recorded. RESULTS: A total of 2,726 patients were included in the analysis. Three hundred ninety-eight (14.6%) patients were taking an ACEI, while 352 (12.9%) patients were taking an ARB prior to hospitalization. After adjusting for comorbidities, age, renal function, and severity of illness based on level of care, ACEI prior to admission was independently associated with decreased need for MV (odds ratio [OR] 0.56, p value 0.003) and mortality (OR 0.45, p value <0.001). Similarly, patients who took ARBs were less likely to require MV when compared to the non-renin-angiotensin-aldosterone system blockade (RAASb) group (7.4% vs 12.2%, p value 0.009, respectively). ARB prior to admission was also independently associated with decreased need for MV (OR 0.46, p value 0.001) and mortality (OR 0.66, p value 0.017) compared to the non-RAASb group. CONCLUSION: Taking ACEIs and ARBs prior to admission for COVID-19 was independently associated with decreased need for mechanical ventilation and in-hospital mortality.

Performance of a pre-procedural Mehran score to predict acute kidney injury after percutaneous coronary intervention.

AIM: Acute kidney injury (AKI) is a known complication of patients undergoing cardiac catheterization or percutaneous coronary interventions (PCI).The Mehran score was developed to identify patients at risk for AKI after cardiac catheterization or PCI, but its use of contrast volume as part of the score calculation limits its application prior to the procedure. In this study, we evaluated the utility of a modified Mehran score that utilizes only pre-procedural data by excluding contrast volume. METHODS: This was done in a retrospective fashion using data from patients who received PCI at our institution between July 2015 and December 2017 by evaluating the discriminative ability of the scoring systems for predicting outcomes through a receiver-operator characteristic curve analysis. RESULTS: One thousand five hundred and seven patients were included in the study. A total of 70 (4.6%) patients developed AKI. The removal of contrast volume from the Mehran score resulted in a small loss of discrimination with AUROC 0.73 vs 0.74, P = .01 for the pre-procedural Mehran and the original Mehran, respectively. When compared to the original score, the pre-procedural Mehran score had a four-category net discrimination index (NRI) of -0.10 and an integrated discrimination index (IDI) for of -0.12. CONCLUSION: Despite a small loss in discrimination, there was no difference in the four-category net discrimination index between the two scores. The pre-procedural modified Mehran score is a useful clinical predictor of the risk of AKI in patients undergoing PCI.

In-Hospital acute ischemic stroke following ST-elevation myocardial infarction.

BACKGROUND: In-hospital ischemic stroke following acute ST-elevation myocardial infarction (STEMI) has not been evaluated on a national scale in the United States. METHODS: We used 2003 to 2014 Nationwide Inpatient Sample data to identify adults with a principal diagnosis of STEMI. Patients were divided into two groups defined by presence or absence of ischemic stroke. Clinical characteristics and in-hospital outcomes were studied using relevant statistics. Multiple linear and logistic regression models identified factors associated with ischemic stroke, national trend of in-hospital stroke incidence and in-hospital mortality. RESULTS: Of 1,842,529 STEMI patients hospitalized from 2003 to 2014, 22,268 (1.2%) developed acute in-hospital ischemic stroke. Those with acute strokes were older (age ≥ 65 years: 70% vs 46%), more likely female (51% vs 33%), and had higher rates of atrial fibrillation (28.9% vs 12.2%) and heart failure (40.5% vs 21.1%). Age and gender adjusted incidence of in-hospital ischemic stroke following STEMI remained stable; 1.4% in 2003 and 1.5% in 2014 (P trend = 0.50). However, age and gender adjusted in-hospital mortality declined in STEMI patients with and without in-hospital ischemic stroke [AOR 0.97 (0.95-0.99) P trend = 0.03, and AOR 0.98 (0.98-0.99) P trend < 0.001, respectively]. Patients with ischemic strokes had higher in-hospital mortality (25.7% Vs 7.2%, p < 0.001), [AOR 2.11, 95% CI (1.92-2.32)]. CONCLUSION: In the United States, the incidence of acute in-hospital stroke remained stable from 2003 to 2014 following STEMI with significant decrease of in-hospital mortality trends. Despite slight improvement in mortality trends, in-hospital mortality rates remained elevated calling for interventions to optimize health care delivery.

Human Papillomavirus Positive Squamous Cell Carcinoma of the Rectum.

Squamous cell carcinoma (SCC) is most commonly seen in the esophagus and anal canal in the gastrointestinal tract. The incidence of SCC of the rectum is infrequent with no clear etiology. There have been limited reported cases of SCC of the rectum caused by human papillomavirus (HPV). Due to the rarity of carcinoma, the management of SCC of the rectum is not standardized. We report a case of a 51-year-old female with an insignificant medical history presenting with hematochezia and weight loss and was found to have HPV-positive SCC of the rectum. This case report emphasizes the importance of work-up, usefulness of HPV testing for high-risk patients, and clinical management of SCC of the rectum.

A Rare Case of an Immunocompetent Male With Zoster Meningitis.

Varicella zoster meningitis is an uncommon complication of herpes zoster, especially in immunocompetent patients. We report a case of a healthy 45-year-old male who developed aseptic meningitis as a result of reactivated varicella zoster virus infection. This case highlights the importance of remaining cognizant of varicella zoster virus as a cause of meningitis in not only the elderly or immunocompromised patients but also in patients who are healthy.

A Rare Case of Severe Hypercalcemia Secondary to Atypical Parathyroid Cystic Adenoma with Negative Sestamibi Scan.

The two types of parathyroid cysts are functional and non-functional cysts. Cystic parathyroid lesions are a rare cause of hypercalcemia and often pose a diagnostic challenge due to the reduced detection on preoperative imaging studies. We, herein, present a rare case of an elderly female presenting to the emergency department with altered mental status associated with hypercalcemic crisis and a negative sestamibi scan. Following surgical resection, pathology revealed the diagnosis of cystic parathyroid adenoma and normalization of serum calcium levels.

Comparison of the Performance of the NCDR CathPCI Score and Mehran Score to Predict Acute Kidney Injury Post-Percutaneous Coronary Intervention.

Background: A comparison of acute kindney injury (AKI) post-percutaneous coronary intervention (PCI) prediction models is lacking. In this study, we aim to compare the National Cardiovascular Data Registry (NCDR) CathPCI score to the Mehran score in acute coronary syndrome (ACS) vs non-ACS patients. Methods: We included patients who received PCI at our facility between July 2015 and December 2017. We excluded patients without a pre- and/or post-PCI serum creatinine, patients on dialysis at the time of PCI and patients with missing variables required to calculate the predictive scoring model. The primary outcome of this study was AKI post-PCI. Performance of the NCDR CathPCI score and the Mehran score were evaluated by comparing the area under the receiver-operating characteristic curve (AUROC) for both scores. Results: The analysis included 1,507 patients. In non-ACS patients, the Mehran score performed better than the NCDR CathPCI score with AUROC 0.75 and 0.68 respectively (p=0.014). When categorized into 4 risk groups, a Mehran score ≥ 2 had a sensitivity of 86% and a Mehran score of ≥ 3 had a specificity of 83% in non-ACS patients. In contrast, when the NCDR CathPCI score was categorized into risk groups, it was not able to predict the risk of AKI (p=0.78) with sensitivity of 0% for the intermediate and high risk group. In ACS patients, the NCDR CathPCI score was superior in predicting the risk for AKI with AUROC 0.79 versus 0.74 (p=.019). Conclusion: In predicting AKI post-PCI, the NCDR CathPCI score performed better in ACS populations, and the Mehran score performed better in the non-ACS population.

Correlation of the Neutrophil-to-Lymphocyte Ratio (NLR) and Platelet-to-Lymphocyte Ratio (PLR) with Contrast-Induced Nephropathy in Patients With Acute Coronary Syndrome Undergoing Percutaneous Coronary Interventions.

Introduction Contrast-induced acute nephropathy (CIN) in patients undergoing percutaneous coronary intervention (PCI) in the setting of acute coronary syndromes (ACS) is associated with adverse outcomes, including longer hospitalization and short and long-term mortality. Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are inflammatory markers that have been validated separately in prior studies as a predictor of CIN in patients with ACS who undergo a left heart catheterization. Our study aims to further investigate the role of NLR and PLR together as markers for predicting CIN in patients with ACS.  Methods A retrospective chart review was performed on a total of 1,577 patients aged 18 - 90 who presented with ACS and underwent PCI between January 2011 to December 2015 at the Florida Hospital Orlando. Cut-off values used for a high PLR and NLR were PLR > 128 and NLR > 2.6. CIN was defined as an increased serum creatinine level by ≥ 0.5 mg/dL, or ≥ 25%, over the baseline value within 72 hours after contrast agent administration. Patients with end-stage renal disease (ESRD) were excluded.  Results Of the 1,577 patients included in the study, 213 (13.51%) patients had CIN. On multivariate logistic regression analysis, high NLR showed an independent association with an elevated risk of CIN (OR 2.03, 95% CI: 1.403 - 3.176, P < 0.001). High PLR did not correlate with CIN (OR 0.831, 95% CI: 0.569 - 1.214, P = 0.339).  Conclusion Elevated NLR is an independent predictor of CIN in patients with acute myocardial infarction (AMI) and may be used to improve on current risk prediction models.

Both Full Glasgow-Blatchford Score and Modified Glasgow-Blatchford Score Predict the Need for Intervention and Mortality in Patients with Acute Lower Gastrointestinal Bleeding.

BACKGROUND: Glasgow-Blatchford score (GBS) has been developed for risk stratification in management of acute upper gastrointestinal (GI) bleeding. However, the performance of GBS in patients with lower GI bleeding is unknown. AIM: To evaluate the performance of full or modified GBS and modified GBS in prediction of major clinical outcomes in patients with lower GI bleeding. METHODS: A retrospective study of patients admitted to a tertiary care center with either non-variceal upper GI bleeding or lower GI bleeding was conducted. The full and modified GBS were calculated for all patients. The primary outcome was a combined outcome of inpatient mortality, need for endoscopic, surgical, or radiologic procedure to control the bleed or treat the underlying source, and need for blood transfusion. RESULTS: A total of 1026 patients (562 cases for upper GI and 464 cases for lower GI) were included in the study. Hospital-based interventions and mortality were significantly higher in upper GI bleeding group. The performance of the full GBS in lower GI bleeding (area under the receiver operating curve (AUROC) 0.78, 95% CI 0.74-0.82) was comparable to full GBS in upper GI bleeding (AUROC 0.77, 95% CI 0.73-0.81) in predicting the primary outcome. Similarly, the performance of modified GBS in lower GI bleeding was shown to be comparable to modified GBS in upper GI bleeding (AUROC 0.78, 95% CI 0.74-0.83 vs. AUROC 0.76 95% CI 0.72-0.80). CONCLUSION: In patients with lower GI bleeding, both full GBS and modified GBS can predict the need for hospital-based interventions and mortality.

Variations in practice patterns and resource utilization in patients treated for chronic obstructive pulmonary disease.

RATIONALE, AIMS, AND OBJECTIVES: Several studies have looked at patient-related variables influencing hospital length of stay (LOS) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). However, there has been increasing recognition that physician-related factors also play a significant role. This study aims to evaluate differences in practice patterns between teaching and nonteaching services and their effect on LOS in a large community hospital. METHODS: A retrospective study of 354 patients admitted to Florida Hospital, Orlando, with AECOPD between January 2009 and December 2011. Patients who presented with acute respiratory failure requiring mechanical ventilation were excluded. Practice patterns of interest were use of oral versus intravenous systemic steroids, use of oral versus intravenous antibiotics, and utilization of consultations. RESULTS: Length of stay was significantly lower in the teaching compared with the nonteaching group (2.80 vs. 5.04 days, P < .001). There was significantly greater use of oral steroids (85% vs. 8.9%, P < .001), greater use of oral antibiotics (72% vs. 33%, P < .001), and lower utilization of consults (0.3 vs. 1.4 consults per patient, P < .001) in the teaching compared with the nonteaching group. The teaching service was independently associated with decreased LOS in a multivariable regression model. However, after adjustment for the difference in practice patterns between the 2 groups, the teaching service was no longer associated with decreased LOS. Of the practice patterns, only utilization of consults was independently associated with increased LOS. CONCLUSIONS: The teaching service had decreased LOS compared with the nonteaching service in patients hospitalized for AECOPD. The observed difference was completely explained by differences in practice patterns between the 2 groups. The study identifies an opportunity for more efficient and cost-effective care of AECOPD patients through streamlining of consultations, use of oral steroids in lieu of IV steroids, and antibiotic stewardship.

Safety and efficacy of ledipasvir/sofosbuvir on hepatitis C eradication in hepatitis C virus/human immunodeficiency virus co-infected patients.

AIM: To evaluate the safety and efficacy of ledipasvir/sofosbuvir on hepatitis C eradication in patients with hepatitis C virus (HCV)/human immunodeficiency virus (HIV) co-infection in an urban HIV clinic. METHODS: A retrospective cohort study of 40 subjects co-infected with HIV-1 and HCV treated with the fixed-dose combination of ledipasvir and sofosbuvir for 12 wk from 2014 to 2016. All patients included were receiving antiretroviral therapy (ART) with HIV RNA values of 100 copies/mL or fewer regardless of baseline HCV RNA level. The primary end point was a sustained virologic response of HCV at 12 wk (SVR12) after the end of therapy. RESULTS: Of the 40 patients enrolled, 55% were black, 22.5% had been previously treated for HCV, and 25% had cirrhosis. The patients were on a wide range of ART. Overall, 39 patients (97.5%) had a SVR 12 after the end of therapy, including rates of 97.1% in patients with HCV genotype 1a and 100% in those with HCV genotype 1b. One patient with HCV genotype 3a was included and achieved SVR12. Rates of SVR12 were similar regardless of previous treatment or the presence of compensated cirrhosis. Only 1 patient experienced relapse at week 12 following treatment and deep sequencing didn't reveal any resistance associated mutation in the NS5A or NS5B region. Interestingly, 7 (17.5%) patients who were adherent to ART experienced HIV viral breakthrough which resolved after continuing the same ART regimen. Two (5%) patients experienced HIV-1 virologic rebound due to noncompliance with HIV therapy, which resolved after resuming the same ART regimen. No severe adverse events were observed and no patient discontinued treatment because of adverse events. The most common adverse events included headache (12.5%), fatigue (10%), and diarrhea (2.5%). CONCLUSION: This retrospective study demonstrated the high rates of SVR12 of ledipasvir/sofosbuvir on HCV eradication in patients co-infected with HCV and HIV, regardless of HCV baseline levels, HCV treatment history or cirrhosis condition. The oral combination of ledipasvir/sofosbuvir represents a safe and well tolerated HCV treatment option that does not require modification for many of the common HIV ART. Occasional HIV virologic rebound occurred but later resolved without the need to change ART.

Prior beta blockers use is independently associated with increased inpatient mortality in patients presenting with acute myocardial infarction.

BACKGROUND: Beta blockers (BBs) are recommended for patients presenting with acute myocardial infarction. However, the effects of prior BBs use on inpatient mortality in patients presenting with acute myocardial infarction (AMI) are unknown. METHODS: This was a retrospective cohort study of patients presenting with AMI in Florida Hospital Orlando from January 1, 2013 to December 31, 2014. Data were collected prospectively, as part of the Acute Coronary Treatment and Intervention Outcomes Network (ACTION) Registry. RESULTS: 1128 patients were included in the analysis, with 354 (31.4%) patients on home BBs and 774 (68.6%) not on home BBs on presentation. Patients in prior BBs group were older, had higher incidence of multiple comorbidities, and were more likely to take cardiovascular medications. During hospitalization, Patients in prior BBs group were more likely to develop decompensated heart failure (9.9% vs. 3.6%, P<0.001), less likely to have STEMI (33.9% vs. 54.4%, P<0.001), and subsequently less PCI (73.2% vs. 81.3%, P=0.002), but higher inpatient mortality (8.8% vs. 4.8%, P=0.009). In multivariable logistic regression analysis, prior BBs use was independently associated with increased inpatient mortality (adjusted OR 3.15, 95% CI 1.44-6.87, P=0.004), as well as in GRACE model (adjusted ratio=1.83, 95% CI 1.01-3.34, P<0.047). However, prior BBs use did not contribute significantly to predict inpatient mortality on the basis of GRACE model in terms of discrimination and calibration. CONCLUSIONS: Prior BBs use was independently associated with increased inpatient mortality, and should be considered a high risk marker for patients presenting with acute myocardial infarction.

Impact of Consultation on Hospital Outcomes and Resource Utilization for Patients with Acute Congestive Heart Failure.

OBJECTIVES: Consultation is an important tool for acquiring subspecialty support when managing patients with acute congestive heart failure (CHF). The effect of consultation on hospital outcomes and resource utilization in CHF is unknown. The objectives of our study were to determine the effect of consultation on outcomes in CHF and to evaluate factors affecting the frequency of consultation. METHODS: Our study was a retrospective cohort study of patients admitted to Florida Hospital Orlando for CHF between January 1, 2011 and December 31, 2013. Data on demographics, number of consultations, length of stay (LOS), readmissions within 30 days, cost of care, and mortality were compared according to the number of consultations. For statistical analysis, analysis of variance, the χ2 test, and multivariate linear regression analysis were used. Risk-adjusted outcomes were reported as observed/expected. RESULTS: A total of 1554 patients were included; 103 (6.6%) patients received no consultation; 482 (31%) received 1; 365 (23.5%) received 2; 229 (14%) received 3; and 375 (24%) received ≥4. Teaching service, age, and African American race were associated with decreased consultation (P < 0.001 for all) and high case-mix index was associated with increased consultation (P < 0.001). Adjusted LOS and costs increased with an increased number of consultations (P < 0.001 for both). There was no difference in adjusted mortality or 30-day readmission rate based on the number of consultations (P = 0.35 and 0.98, respectively). CONCLUSIONS: Increased consultation with patients with CHF is associated with increased costs and LOS without improved mortality or readmission rate. Decreased utilization of consultations by the teaching service suggests that there is an opportunity to decrease utilization of healthcare resources by streamlining the utilization of consultations.

Pseudomembranous aspergillar tracheobronchitis in a non-neutropenic critically ill patient in the intensive care unit.

Invasive aspergillosis is an important cause of morbidity and mortality among immunocompromised patients. Prolonged neutropenia is the most common risk factor. It has rarely been reported to occur in non-neutropenic critically ill patients in the intensive care unit setting. Mortality rate in this group has been reported to be as high as 92%. We report a case of tracheobronchial aspergillosis in a non-neutropenic critically ill patient to highlight the fact that critically ill patients admitted in the intensive care unit can develop opportunistic infections such as invasive aspergillosis even in the absence of classic risk factors and prior history of immunosuppression. Early diagnosis and prompt initiation of antifungal therapy may improve the outcome and decrease mortality rate.

Monocular diplopia-associated migraine-like headache induced by nicotine withdrawal.

We describe an extremely rare case of migraine-associated monocular diplopia developed in a 23-year-old man after sudden cessation of smoking. The physical examination and brain MRI scan were unremarkable. The symptoms resolved after starting nicotine patch. We reviewed the literature and discussed the diagnosis and possible mechanism of this phenomenon.

Signet Cell in the Brain: A Case Report of Leptomeningeal Carcinomatosis as the Presenting Feature of Gastric Signet Cell Cancer.

Malignant infiltration of pia and arachnoid mater, referred to as leptomeningeal carcinomatosis (LMC), is a rare complication of gastric carcinoma. The most common underlying malignancy in patients with LMC are leukemia, breast cancer, lymphoma, and lung cancer. We report a case of gastric adenocarcinoma that presented with LMC in the absence of overt gastrointestinal signs or symptoms. A 56-year-old Hispanic woman presented to the hospital with a three-week history of intermittent headaches and visual blurring. An initial brain imaging showed infarction in the distribution of right posterior inferior cerebellar artery (PICA) along with communicating hydrocephalus. She underwent ventriculoperitoneal (VP) shunt placement with improvement in her symptoms. Two months later she presented again with deterioration in her mental status. Imaging studies and cerebrospinal fluid (CSF) analysis confirmed the diagnosis of LMC. Further studies determined the primary tumor to be signet ring cell gastric adenocarcinoma. However, she did not have any preceding gastrointestinal symptoms. In light of the poor prognosis, the patient's family proceeded with comfort care measures. Our case portrays a rare presentation of gastric adenocarcinoma with LMC without other distant organ metastatic involvement. It also illustrates the occult nature of gastric carcinoma and signifies the importance of neurologic assessment of patients, with or at risk of gastric carcinoma. â€‹It also raises a theoretical concern for VP shunt as a potential conduit of malignant cells from the abdomen to the central nervous system, which may serve as an important susbtrate for future research.

Predictors of the Need for Therapeutic Intervention in Older Adult Patients With a Nonvariceal Gastrointestinal Bleed.

OBJECTIVE: Gastrointestinal bleeding (GIB) is a common cause of hospitalization in the older adult population. The aim of the study was to identify factors that are associated with the need for a therapeutic intervention in patients older than 65 years with nonvariceal GIB. METHODS: This is a retrospective cohort study of older adult patients admitted to a tertiary care center between 2009 and 2011 with nonvariceal GIB. The primary outcome was a composite endpoint of inpatient mortality or need for an endoscopic, surgical, or radiologic procedure to control the bleed or to treat the underlying source of the bleed. RESULTS: A total of 314 patients were included. In-hospital mortality was 1.3% (4 patients). An intervention to control the bleeding was performed in 15 patients (4.8%). Four patients (1.3%) needed a nonurgent intervention. Twenty-three patients (7.23%) had the primary combined outcome of in-hospital mortality or need for any therapeutic endoscopic, surgical, or radiologic intervention. Factors that were independently associated with the primary outcome were systolic blood pressure within the first 24 hours of <90 mm Hg (odds ratio 3.05, 95% confidence interval 1.08-8.59, P = 0.001), and initial hemoglobin of <7 g/dL (odds ratio 4.81, 95% confidence interval 1.56-14.74, P = 0.006). CONCLUSIONS: Nonvariceal GIB in older adult patients ceases spontaneously in most patients without an invasive intervention. Systolic blood pressure within the first 24 hours of <90 mm Hg and an initial hemoglobin level of <7 g/dL could be used to identify high-risk patients who may benefit from an urgent therapeutic intervention.

Comparison of hospital outcomes and resource use in acute COPD exacerbation patients managed by teaching versus nonteaching services in a community hospital.

RATIONALE, AIMS, AND OBJECTIVES: The impact of teaching versus nonteaching services on outcomes and resource use in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is unknown. The aim of the study is to evaluate the impact of an internal medicine teaching service compared to a nonteaching service on outcomes and resource use in patients admitted with AECOPD in a community teaching hospital. METHODS: A retrospective cohort study of patients admitted for a primary diagnosis of chronic obstructive pulmonary disease exacerbation to Florida Hospital Orlando, a large community teaching hospital, between January 1, 2011, and December 31, 2014. Data were extracted from Premier administrative database. Risk adjusted length of stay (LOS), cost of hospitalization, 30-day readmissions, and mortality rate were measured. Risk adjustment for outcomes was based on Premier CareScience methodology. RESULTS: A total of 1419 patients were included, 306 in the teaching group and 1113 in the nonteaching group. Risk adjusted cost and LOS were significantly lower in the teaching group compared to the nonteaching group (observed/expected cost 0.66 vs 1.06, P < .001) and (observed/expected LOS 0.93 vs 1.69, P < .001), respectively. No significant difference was found between the 2 groups in risk adjusted mortality and readmissions (P = .48 and .89, respectively). Use of consults was significantly lower in the teaching groups with 73% vs 31% of the patient in the teaching group had no consults compared to the nonteaching group (P < .001). The teaching service was significantly associated with decreased use of consults after adjustment for other variables (odds ratio, 0.17, 95% CI, 0.15-0.23, P < .001). CONCLUSION: The teaching service had more favorable outcomes compared to nonteaching services in patients hospitalized for AECOPD. The physician practice model has a major impact on the cost, LOS, and use of consults in patients with AECOPD.
