Multidisciplinary Perspectives of Challenges in Infective Endocarditis Complicated by Septic Embolic-Induced Acute Myocardial Infarction.

BACKGROUND: Infective endocarditis (IE) management is challenging, usually requiring multidisciplinary collaboration from cardiologists, infectious disease specialists, interventional cardiologists, and cardiovascular surgeons, as more than half of the cases will require surgical procedures. Therefore, it is essential for all healthcare providers involved in managing IE to understand the disease's characteristics, potential complications, and treatment options. While systemic embolization is one of the most frequent complications of IE, the coronary localization of emboli causing acute myocardial infarction (AMI) is less common, with an incidence ranging from 1% to 10% of cases, but it has a much higher rate of morbidity and mortality. There are no guidelines for this type of AMI management in IE. METHODS: This narrative review summarizes the current knowledge regarding septic coronary embolization in patients with IE. Additionally, this paper highlights the diagnosis and management challenges in such cases, particularly due to the lack of protocols or consensus in the field. RESULTS: Data extracted from case reports indicate that septic coronary embolization often occurs within the first two weeks of the disease. The aortic valve is most commonly involved with vegetation, and the occluded vessel is frequently the left anterior descending artery. Broad-spectrum antibiotic therapy followed by targeted antibiotic therapy for infection control is essential, and surgical treatment offers promising results through surgical embolectomy, concomitant with valve replacement or aspiration thrombectomy, with or without subsequent stent insertion. Thrombolytics are to be avoided due to the increased risk of bleeding. CONCLUSIONS: All these aspects should constitute future lines of research, allowing the integration of all current knowledge from multidisciplinary team studies on larger patient cohorts and, subsequently, creating a consensus for assessing the risk and guiding the management of this potentially fatal complication.

A case of celiac plexus block causing iatrogenic Cushing's syndrome.

Treatment with corticosteroids can lead to iatrogenic Cushing's syndrome when used for longer intervals and in high doses. Less common administration routes may conceal the exposure, raising the possibility of misdiagnosis and mismanagement.

Clinical and Radiological Characterization of Central Nervous System Involvement in Nocardiosis: A 20-Year Experience.

Background This study aimed to present the clinical and radiological characteristics and the outcomes of patients with Nocardia infection of the central nervous system (CNS). Methodology We conducted a retrospective review of patients aged 18 and older admitted between August 1998 and November 2018 with culture-proven nocardiosis and CNS involvement. Results Out of 110 patients with nocardiosis, 14 (12.7%) patients had CNS involvement. The median age was 54.5 (27, 86) years, and 12 (85.7%) patients were male. Overall, 12 (85.7%) patients were immunosuppressed on high doses of glucocorticoids; seven (50%) patients were solid organ transplant recipients. Only eight (57.1%) patients had neurological symptoms at presentation, and the rest were diagnosed with CNS involvement after imaging surveillance. Three distinct radiologic patterns were identified, namely, single or multiple abscesses, focal cerebritis, and small, septic embolic infarcts. All isolates of Nocardia were susceptible to trimethoprim/sulfamethoxazole and amikacin, with susceptibility to linezolid and carbapenems being 90.9% and 79.5%, respectively. Despite receiving antibiotic therapy, six (42.8%) patients died, most of them within weeks of initial admission. All surviving patients underwent prolonged antimicrobial therapy until the resolution of MRI abnormalities. All solid organ transplant recipients recovered. Conclusions Nocardia CNS infection was a rare condition, even among a large, immunosuppressed patient population. CNS imaging surveillance is paramount for immunosuppressed patients with nocardiosis, as CNS involvement influences the choice and duration of therapy. Nocardia antibiotic susceptibility varied widely between strains and the empiric therapy should consist of multiple classes of antimicrobials with CNS penetration. Mortality was high, but all solid organ transplant recipients recovered.

Expanding the Role of the Surgical Preoperative Evaluation Clinic: Impact on Risk and Quality Outcome Measures.

Objective: To prove that inpatient-adjusted surgical risk and quality outcome measures can be considerably impacted by interventions to improve documentation in the preoperative evaluation (POE) clinic. Patients and Methods: We designed a quality improvement project with a multidisciplinary team in our POE clinic to more accurately reflect surgical risk and impact expected surgical quality outcomes through improved documentation. Interventions included an improved patient record acquisition process and extensive POE provider education regarding patient comorbidities' documentation. For patients admitted after their planned operations, POE clinic comprehensive evaluation notes were linked to inpatient History and Physical notes. High complexity patients seen from October 1, 2018 to December 31, 2018 were the preintervention cohort, and the patients seen from January 1, 2019 to December 31, 2019 were the postintervention cohort. Results: The primary outcome measures included the total number of coded diagnoses per encounter and the number of coded hierarchical condition categories per encounter. The secondary outcomes included the calculated severity of illness, risk of mortality, case-mix index, and risk-adjustment factor. Postintervention results show statistically significant increases in all primary outcomes with a P<.05. All secondary outcome measures reported positive change. Conclusion: Our interventions confirm that a comprehensive POE and thorough documentation provide a more accurate clinical depiction of the preoperative patient, which in turn impacts quality outcomes in inpatient surgical settings. These results are impactful for direct and indirect patient care and publicly reported hospital and provider level performance data.

Acute Onset of Heart Failure and Renal Failure Due to Pacemaker Syndrome.

Here, we report the outcome of an 87-year-old man with permanent non-valvular atrial fibrillation who initially presented with complete heart block and received a single right ventricle lead pacemaker programmed to ventricular demand pacing (VVIR). Over the next 10 months, the patient was readmitted to the hospital four times with recurrent edema, pleural effusions, and ascites. He was diagnosed with new onset systolic heart failure with mid-range (40-49%) ejection fraction and cardiorenal syndrome requiring dialysis. The underlying cause of his presentation was determined to be pacemaker syndrome mediated by new onset severe tricuspid regurgitation. He was treated with reimplantation of a pacemaker with His bundle pacing with subsequent improvement in his cardiac status and renal function. Implantation of dual-chamber pacing (DDDR) or His bundle pacing to achieve a narrow QRS complex over ventricular demand pacemaker is recommended whenever possible to reduce the incidence of pacemaker syndrome and improve patient outcomes.

Invasive Nocardiosis Versus Colonization at a Tertiary Care Center: Clinical and Radiological Characteristics.

Objective: To describe the clinical and radiographic findings in a large cohort of patients with positive cultures for Nocardia emphasizing the differences between invasive disease and colonization. Patients and Methods: We conducted a single-center, retrospective cohort study of 133 patients with a positive Nocardia isolate between August 1, 1998, and November 30, 2018, and a computed tomography (CT) of the chest within 30 days before or after the bacteria isolation date. Results: Patients with colonization were older (71 vs 65 years; P=.004), frequently with chronic obstructive pulmonary disease (56.8% vs 16.9%; P<.001) and coronary artery disease (47.7% vs 27%, P=.021), and had Nocardia isolated exclusively from lung specimens (100% vs 83.1%; P=.003). On CT of the chest, they had frequent airway disease (84.1% vs 51.7%; P<.001). Patients with invasive nocardiosis had significantly (P<.05) more diabetes, chronic kidney disease, solid organ transplant, use of corticosteroids, antirejection drugs, and prophylactic sulfa. They had more fever (25.8% vs 2.3%; P<.001), cutaneous lesions (14.6% vs 0%; P=.005), fatigue (18% vs 0%; P=.001), pulmonary nodules (52.8% vs 27.3%; P=.006), and free-flowing pleural fluid (63.6% vs 29.4%; P=.024). The patterns of nodule distribution were different-diffuse for invasive nocardiosis and peribronchiolar for Nocardia colonization. Conclusion: The isolation of Nocardia in sputum from a patient with respiratory symptoms does not equal active infection. Only by combining clinical and chest CT findings, one could better differentiate between invasive nocardiosis and Nocardia colonization.

Continuous Glucose Monitoring for Patients with COVID-19 Pneumonia: Initial Experience at a Tertiary Care Center.

OBJECTIVE: Patients hospitalized with COVID-19 and hyperglycemia require frequent glucose monitoring, usually performed with glucometers. Continuous glucose monitors (CGMs) are common in the outpatient setting but not yet approved for hospital use. We evaluated CGM accuracy, safety for insulin dosing, and CGM clinical reliability in 20 adult patients hospitalized with COVID-19 and hyperglycemia. METHODS: Study patients were fitted with a remotely monitored CGM. CGM values were evaluated against glucometer readings. The CGM sensor calibration was performed if necessary. CGM values were used to dose insulin, without glucometer confirmation. RESULTS: CGM accuracy against glucometer, expressed as mean absolute relative difference (MARD), was calculated using 812 paired glucometer-CGM values. The aggregate MARD was 10.4%. For time in range and grades 1 and 2 hyperglycemia, MARD was 11.4%, 9.4%, and 9.1%, respectively, with a small variation between medical floors and intensive care units. There was no MARD correlation with mean arterial blood pressure levels, oxygen saturation, daily hemoglobin levels, and glomerular filtration rates. CGM clinical reliability was high, with 99.7% of the CGM values falling within the "safe" zones of Clarke error grid. After CGM placement, the frequency of glucometer measurements decreased from 5 to 3 and then 2 per day, reducing nurse presence in patient rooms and limiting viral exposure. CONCLUSION: With twice daily, on-demand calibration, the inpatient CGM use was safe for insulin dosing, decreasing the frequency of glucometer fingersticks. For glucose levels >70 mg/dL, CGMs showed adequate accuracy, without interference from vital and laboratory values.

When a "Low T" Diagnosis Can Be the Clue to a More Complex Problem.

Male hypogonadism remains a poorly evaluated and managed clinical condition despite the availability of clinical guidelines. We present a case of a male patient diagnosed with secondary hypogonadism related to partial empty sella syndrome, whose clinical course was complicated by a hypotensive near-syncopal event. Although initial hypopituitarism symptoms could be subtle and nonspecific and could involve only one hormonal axis, a thorough evaluation of the pituitary function may identify additional deficiencies such as a subclinical chronic adrenal insufficiency that may become manifest during situations of increased physiological stress with potential life-threatening consequences.

Invasive Nocardiosis in Transplant and Nontransplant Patients: 20-Year Experience in a Tertiary Care Center.

OBJECTIVE: To present the clinical characteristics and outcome of transplant and nontransplant patients with invasive nocardiosis. PATIENTS AND METHODS: We conducted a retrospective chart review of 110 patients 18 years and older diagnosed with culture-proven invasive nocardiosis (defined as the presence of clinical signs and/or radiographic abnormalities) between August 1, 1998, and November 30, 2018. Information on demographic, clinical, radiographic, and microbiological characteristics as well as mortality was collected. RESULTS: One hundred ten individuals with invasive nocardiosis were identified, of whom 54 (49%) were transplant and 56 nontransplant (51%) patients. Most transplant patients were kidney and lung recipients. The overall mean age was 64.9 years, and transplant patients had a higher prevalence of diabetes and chronic kidney disease. A substantial proportion of nontransplant patients were receiving corticosteroids (39%), immunosuppressive medications (16%), and chemotherapy (9%) and had chronic obstructive pulmonary disease (20%), rheumatologic conditions (18%), and malignant neoplasia (18%). A higher proportion of transplant patients (28%) than nontransplant patients (4%) received trimethoprim-sulfamethoxazole prophylaxis. In both groups, the lung was the most common site of infection. Seventy percent of all Nocardia species isolated were present in almost equal proportion: N brasiliensis (16%), N farcinica (16%), N nova (15%), N cyriacigeorgia (13%), and N asteroides (11%). More than 90% of isolates were susceptible to trimethoprim-sulfamethoxazole, linezolid, and amikacin. There was no significant difference in mortality between the 2 groups at 1, 6, and 12 months after the initial diagnosis. CONCLUSION: The frequency of invasive Nocardia infection was similar in transplant and nontransplant patients and mortality at 1, 6, and 12 months was similar in both groups. Trimethoprim-sulfamethoxazole prophylaxis failed to prevent Nocardia infection.

Home Telemonitoring to Reduce Readmission of High-Risk Patients: a Modified Intention-to-Treat Randomized Clinical Trial.

BACKGROUND: Home telemonitoring has been used with discharged patients in an attempt to reduce 30-day readmissions with mixed results. OBJECTIVE: To assess whether home 30-day telemonitoring after discharge for patients at high risk of readmission would reduce readmissions or mortality. DESIGN: Prospective, randomized controlled trial. PATIENTS: We compared 30-day readmission rates and mortality for patients at high risk for readmission who received home telemonitoring versus standard care between November 1, 2014, and November 30, 2018, in 2 tertiary care hospitals. INTERVENTIONS: The intervention group received home-installed equipment to measure blood pressure, heart rate, pulse oximetry, weight if heart failure was present, and glucose if diabetes was present. Results were transmitted daily and reviewed by a nurse. Both groups received standard care. MAIN MEASURES: The primary outcome was a composite end point of hospital readmission or death within 30 days after discharge. The secondary outcome was an emergency department visit within 30 days after discharge. KEY RESULTS: A total of 1380 participants (mean [SD] age, 66 [14] years; 722 [52.3%] men and 658 [47.7%] women) participated in this study. Using a modified intention-to-treat analysis, the risk of readmission or death within 30 days among patients at high readmission risk was 23.7% (137/578) in the control group and 18.2% (87/477) in the telemonitoring group (absolute risk difference, - 5.5% [95% CI, - 10.4 to - 0.6%]; relative risk, 0.77 [95% CI, 0.61 to 0.98]; P = .03). Emergency department visits occurred within 30 days after discharge in 14.2% (81/570) of patients in the control group and 8.6% (40/464) of patients in the telemonitoring group (absolute risk difference, - 5.6% [95% CI, - 9.4 to - 1.8%]; relative risk, 0.61 [95% CI, 0.42 to 0.87]; P = .005). CONCLUSIONS: Thirty days of postdischarge telemonitoring may reduce readmissions of high-risk patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02136186.

Patients Threatening Harm to Others Evaluated in the Emergency Department under the Florida Involuntary Hold Act (Baker Act).

OBJECTIVES: This study describes the specific threats of harm to others that led to the use of the Baker Act, the Florida involuntary hold act for emergency department (ED) evaluations. The study also summarizes patient demographics, concomitant psychiatric diagnoses, and emergent medical problems. METHODS: This is a retrospective review of 251 patients evaluated while on involuntary hold from January 1, 2014 through November 30, 2015 at a suburban acute care hospital ED. The data that were collected included demographic information, length of stay, reason for the involuntary hold, psychiatric disorder, substance use, medical illness, and violence in the ED. The context of the homicidal threat also was collected. RESULTS: We found that 13 patients (5.2%) were homicidal. Three patients had homicidal ideations alone, whereas 10 made homicidal threats toward others. Of the 10 making homicidal threats, 7 named a specific person to harm. Ten of the 13 homicidal patients (76.9%) also were suicidal. Eleven patients (84.6%) had a psychiatric disorder: 9 patients (69.2%) had a depressive disorder and 8 patients (61.5%) had a substance use disorder. Eight patients had active medical problems that required intervention in the ED. CONCLUSIONS: We found that three-fourths of patients expressing homicidal threats also were suicidal. The majority of patients making threats of harm had a specific plan of action to carry out the threat. It is important to screen any patient making homicidal threats for suicidal ideation. If present, there is a need to implement immediate management appropriate to the level of the suicidal threat, for the safety of the patient. Eighty-five percent of patients making a homicidal threat had a previously documented psychiatric disorder, the most common being a depressive disorder. This finding differs from previous studies in which psychosis predominated. More than 60% of homicidal patients had an unrelated medical disorder requiring intervention. It is important not to overlook these medical disorders while focusing on the psychiatric needs of the patient; most of our homicidal patients proved to be cooperative in the ED setting.

Patients on Involuntary Hold Status in the Emergency Department.

OBJECTIVES: Patients requiring involuntary holds are frequently seen in the emergency department (ED). Much of what is known comes from studies of patients at urban academic centers. Our aim was to describe the demographic and clinical characteristics of patients who were evaluated while on involuntary status at a suburban ED. METHODS: The medical records of patients seen in the ED requiring involuntary hold status between January 1, 2014 and November 30, 2015 were reviewed. Demographic and clinical variables including medical and psychiatric comorbidity were collected. A subanalysis was performed comparing patients who attempted suicide with all other involuntary patients. RESULTS: Two hundred fifty-one patient records were reviewed; 215 patients (85.3%) had psychiatric disorders-depression was the most common (57%)-and 108 patients (43%) had substance use disorders. Only 13 patients (5.2%) had neither a psychiatric disorder nor a history of substance use. Twenty-two patients (8.8%) were violent in the ED. Thirteen patients (5.2%) were readmitted, and 1 patient died within 30 days of discharge from the ED. One hundred twenty-four patients (49.4%) had medical disorders. Suicidal ideation was the most common reason for involuntary hold (n = 185, 73.7%); 63 patients (25.1%) attempted suicide. Compared with other involuntary patients, the patients who attempted suicide were less likely to use opiates (odds ratio 0.27, 95% confidence interval 0.08-0.94, P = 0.04) and to have medical disorders (odds ratio 0.52, 95% confidence interval 0.28-0.98, P = 0.04). CONCLUSIONS: Patients in this study differed from those in urban centers with respect to sex and psychiatric disorder; however, substance misuse was common in both settings. Suicidal ideation including suicide attempt was the most common reason for involuntary status. Patients who attempted suicide were similar to other patients on involuntary hold with respect to demographic and clinical variables.

Patient portal adoption and use by hospitalized cancer patients: a retrospective study of its impact on adverse events, utilization, and patient satisfaction.

BACKGROUND: Portal use has been studied among outpatients, but its utility and impact on inpatients is unclear. This study describes portal adoption and use among hospitalized cancer patients and investigates associations with selected safety, utilization, and satisfaction measures. METHODS: A retrospective review of 4594 adult hospitalized cancer patients was conducted between 2012 and 2014 at Mayo Clinic in Jacksonville, Florida, comparing portal adopters, who registered for a portal account prior to hospitalization, with nonadopters. Adopters were classified by their portal activity during hospitalization as active or inactive inpatient users. Univariate and several logistic and linear regression models were used for analysis. RESULTS: Of total patients, 2352 (51.2%) were portal adopters, and of them, 632 (26.8%) were active inpatient users. Portal adoption was associated with patients who were young, female, married, with higher income, and had more frequent hospitalizations (P < .05). Active inpatient use was associated with patients who were young, married, nonlocals, with higher disease severity, and were hospitalized for medical treatment (P < .05). In univariate analyses, self-management knowledge scores were higher among adopters vs nonadopters (84.3 and 80.0, respectively; P = .01) and among active vs inactive inpatient users (87.0 and 83.3, respectively; P = .04). In regression models adjusted for age and disease severity, the association between portal behaviors and majority of measures were not significant (P > .05). CONCLUSIONS: Over half of our cancer inpatients adopted a portal prior to hospitalization, with increased adoption associated with predisposing and enabling determinants (eg: age, sex, marital status, income), and increased inpatient use associated with need (eg: nonlocal residence and disease severity). Additional research and greater effort to expand the portal functionality is needed to impact inpatient outcomes.

Patient portal use and hospital outcomes.

Objectives: To determine whether use of a patient portal during hospitalization is associated with improvement in hospital outcomes, 30-day readmissions, inpatient mortality, and 30-day mortality. Materials and Methods: We performed a retrospective propensity score-matched study that included all adult patients admitted to Mayo Clinic Hospital in Jacksonville, Florida, from August 1, 2012, to July 31, 2014, who had signed up for a patient portal account prior to hospitalization (N = 7538). Results: Out of the admitted patients with a portal account, 1566 (20.8%) accessed the portal while in the hospital. Compared to patients who did not access the portal, patients who accessed the portal were younger (58.8 years vs 62.3 years), had fewer elective admissions (54.2% vs 64.1%), were more frequently admitted to medical services (45.8% vs 35.2%), and were more likely to have liver disease (21.9% vs 12.9%) and higher disease severity scores (0.653 vs 0.456). After propensity score matching, there was no statistically significant difference between the 2 cohorts with respect to 30-day readmission (P = .13), inpatient mortality (P = .82), or 30-day mortality (P = .082). Conclusion: Use of the patient portal in the inpatient setting may not improve hospital outcomes. Future research should examine the association of portal use with more immediate inpatient health outcomes such as patient experience, patient engagement, medication reconciliation, and prevention of adverse events.

Mayo Registry for Telemetry Efficacy in Arrest Study: An Assessment of the Utility of Telemetry in Predicting Clinical Decompensation.

INTRODUCTION: Our study assesses the utility of telemetry in identifying decompensation in patients with documented cardiopulmonary arrest. METHODS: A retrospective review of inpatients who experienced a cardiopulmonary arrest from May 1, 2008, until June 30, 2014, was performed. Telemetry records 24 hours prior to and immediately preceding cardiopulmonary arrest were reviewed. Patient subanalyses based on clinical demographics were made as well as analyses of survival comparing patients with identifiable rhythm changes in telemetry to those without. RESULTS: Of 242 patients included in the study, 75 (31.0%) and 110 (45.5%) experienced telemetry changes at the 24-hour and immediately preceding time periods, respectively. Of the telemetry changes, the majority were classified as nonmalignant (n = 50, 66.7% and n = 66, 55.5% at 24 hours prior and immediately preceding, respectively). There was no difference in telemetry changes between intensive care unit (ICU) and non-ICU patients and among patients stratified according to the American Heart Association telemetry indications. There was no difference in survival when comparing patients with telemetry changes immediately preceding and at 24 hours prior to an event (n = 30, 27.3% and n = 15, 20.0%) to those without telemetry changes during the same periods (n = 27, 20.5% and n = 42, 25.2%; P = .22 and .39). CONCLUSION: Telemetry has limited utility in predicting clinical decompensation in the inpatient setting.

Descriptive Analysis of Medication Administration During Inpatient Cardiopulmonary Arrest Resuscitation (from the Mayo Registry for Telemetry Efficacy in Arrest Study).

Advanced cardiovascular life support guidelines exist, yet there are variations in clinical practice. Our study aims to describe the utilization of medications during resuscitation from in-hospital cardiopulmonary arrest. A retrospective review of patients who suffered a cardiopulmonary arrest from May 2008 to June 2014 was performed. Clinical and resuscitation data, including timing and dose of medications used, were extracted from the electronic medical record and comparisons made. A total of 94 patients were included in the study. Patients were divided into different groups based on the medication combination used during resuscitation: (1) epinephrine; (2) epinephrine and bicarbonate; (3) epinephrine, bicarbonate, and calcium; (4) epinephrine, bicarbonate, and epinephrine drip; and (5) epinephrine, bicarbonate, calcium, and epinephrine drip. No difference in baseline demographics or clinical data was present, apart from history of dementia and the use of calcium channel blockers. The number of medications given was correlated with resuscitation duration (Spearman's rank correlation = 0.50, p <0.001). The proportion of patients who died during the arrest was 12.5% in those who received epinephrine alone, 30.0% in those who received only epinephrine and bicarbonate, and 46.7% to 57.9% in the remaining groups. Patients receiving only epinephrine had shorter resuscitation durations compared to that of the other groups (p <0.001) and improved survival (p = 0.003). In conclusion, providers frequently use nonguideline medications in resuscitation efforts for in-hospital cardiopulmonary arrests. Increased duration and mortality rates were found in those resuscitations compared with epinephrine alone, likely due to the longer resuscitation duration in the former groups.

Mayo registry for telemetry efficacy in arrest study: An evaluation of the feasibility of the do not intubate code status.

Introduction: Guidelines recommend discussing code status with patients on hospital admission. No study has evaluated the feasibility of a full code with do not intubate (DNI) status. Methods: A retrospective analysis of patients who experienced a cardiopulmonary arrest was performed between May 1, 2008 and June 20, 2014. A descriptive analysis was created based on whether patients required mechanical ventilatory support during the hospitalization and comparisons were made between both patient subsets. Results: A total of 239 patients were included. Almost all (n = 218, 91.2%) required intubation during the hospitalization. Over half (n = 117, 53.7%) were intubated on the same day as the cardiopulmonary arrest and 91 patients (41.7%) were intubated at the time of arrest. Comparisons between intubated and non-intubated patients showed little differences in clinical characteristics, except for a higher proportion of medical cardiac etiology for admission in patients who did not require intubation (n = 10, 47.6% versus n = 55, 25.2%; p = 0.18) and initial arrest rhythm of ventricular tachycardia/fibrillation (n = 8, 38.1% versus n = 50, 22.9%; p = 0.37). No differences in 24-hour and posthospital survivals were present. Conclusion: Mechanical ventilatory support is commonly utilized in patients who experience a cardiopulmonary arrest. The DNI status may not be a feasible code status option for most patients.
