Normal-Flow Low-Gradient Aortic Stenosis: Comparing the U.S. and European Guidelines.

Patients with normal-flow low-gradient (NFLG) severe aortic stenosis present both diagnostic and management challenges, with debate about the whether this represents true severe stenosis and the need for valve replacement. Studies exploring the natural history without intervention have shown similar outcomes of patients with NFLG severe aortic stenosis to those with moderate aortic stenosis and better outcomes after valve replacement than those with low-flow low-gradient severe aortic stenosis. Most studies (all observational) have shown that aortic valve replacement was associated with a survival benefit vs surveillance. Based on available data, the European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines and European Association of Cardiovascular Imaging/American Society of Echocardiography suggest that these patients are more likely to have moderate aortic stenosis. This clinical entity is not mentioned in the American Heart Association/American College of Cardiology guidelines. Here we review the definition of NFLG severe aortic stenosis, potential diagnostic algorithms and points of error, the data supporting different management strategies, and the differing guidelines and outline the unanswered questions in the diagnosis and management of these challenging patients.

Cerebral embolic protection device utilization and outcomes in transcatheter aortic valve replacement: A nationally representative propensity matched analysis.

INTRODUCTION: In patients undergoing transcatheter aortic valve replacement (TAVR), cerebral embolic protection devices (CEPD) are used to possibly diminish the risk of periprocedural stroke. Trends and outcomes of CEPD usage in TAVR are not well characterized. METHODS: National readmission databases (NRD) 2017-2019 was used to identify hospital admissions for TAVR using ICD-10 codes, with versus without Sentinel CEPD. Primary outcomes of the study were in-hospital and 30-day stroke. Secondary outcomes include in-hospital mortality, 30-day mortality, 30-day readmission rate, and other procedural complications. We matched both cohorts using propensity score matching (PSM) and performed logistic regression to compute the odds ratios (ORs) and corresponding 95 % confidence intervals (CI). RESULTS: Out of 190,837 TAVR admissions in the United States, 10,643 (5.6 %) patients had TAVR with Sentinel CEPD. After propensity score matching, our cohort included 10,503 patients with CEPD and 10,541 without CEPD. Trends in CEPD utilization are noted in Fig. 1. In the PSM cohort, Sentinel CEPD was not associated with decreased risk of in-hospital stroke (1.9 % vs. 1.8 %, OR: 0.98, 95 % CI: 0.76-1.26, p = 0.88), 30-day stroke (2.1 % vs. 2.1 %, OR: 1.01, 95 % CI: 0.78-1.30, p = 0.96), or 30-day mortality (1.3 % vs. 1.0 %, OR: 0.74, 95 % CI: 0.51-1.07, p = 0.11) when compared to TAVR without CEPD. Other in-hospital and short-term outcomes post-TAVR were not impacted by Sentinel CEPD usage, including acute kidney injury, vascular complications, paravalvular leak, cardiogenic shock, circulatory support, or permanent pacemaker (Table 1). CONCLUSION: In this nationally representative cohort, Sentinel CEPD utilization during transfemoral TAVR for stroke prevention was not associated with reduced odds of in-hospital stroke, 30-day stroke, or 30-day mortality. Future studies should focus on optimizing patient selection for CEPD and establishing predictive models to identify the subset of TAVR patients with higher risk for periprocedural stroke who might benefit from CEPD.

Impact of COVID-19 pandemic on the volume, cost, and outcomes of cardiac electrophysiology procedures in the United States.

BACKGROUND: During the COVID-19 pandemic, professional societies recommended deferral of elective procedures for optimal resource utilization. OBJECTIVE: We sought to assess changes in procedural trends and outcomes of electrophysiology (EP) procedures during the pandemic. METHODS: National Inpatient Sample databases were used to identify all EP procedures performed in the United States (2016-2020) by International Classification of Diseases, Tenth Revision codes. We evaluated trends in utilization, cost/revenue, and outcomes from EP procedures performed. RESULTS: An estimated 1.35 million EP procedures (82% devices and 18% catheter ablations) were performed (2016-2020) with significant yearly uptrend. During the pandemic, there was a substantial decline in EP procedure utilization from a 5-year peak of 298 cases/million population in the second quarter of 2019 to a nadir of 220 cases in the second quarter of 2020. In 2020, the pandemic was associated with the loss of 50,233 projected EP procedures (39,337 devices and 10,896 ablations) with subsequent revenue loss of $7.06 billion. This deficit was driven by revenue deficit from dual-chamber permanent pacemaker (PPM) utilization ($2.88 billion, 49.3% of lost cases), ablation procedures ($1.84 billion, 21.7% of lost cases), and implantable cardioverter-defibrillator implantation ($1.36 billion, 12.0% of lost cases). To the contrary, there was a 9.4% increase in the utilization of leadless PPM. EP device implantation during the pandemic was associated with higher adverse in-hospital events (9.4% vs 8.0%; P < .001). CONCLUSION: In the United States, the significant decline in EP procedures during the pandemic was primarily driven by the reduction in dual-chamber PPM utilization, followed by arrhythmia ablation and implantable cardioverter-defibrillator implantation. There was a substantial increase in leadless PPM utilization during the pandemic.

Impact of concomitant surgical interventions on outcomes of septal myectomy in obstructive hypertrophic cardiomyopathy.

BACKGROUND: Septal myectomy (SM) is offered to symptomatic patients with obstructive hypertrophic cardiomyopathy (oHCM) despite medical therapy. Frequently, patients undergo concomitant planned or ad-hoc mitral valve replacement (MVR), aortic valve replacement (SAVR), or coronary artery bypass grafting (CABG). OBJECTIVES: We sought to assess characteristics and outcomes of patients with oHCM undergoing concomitant surgical interventions at the time of SM. METHODS: The National Readmission Databases were used to identify all SM admissions in the United States (2010-2019). Patients undergoing SM were stratified into: isolated SM (±MV repair), SM + CABG only, SM + MVR, SM + SAVR, and SM + MVR + SAVR. Primary outcomes were in-hospital mortality, in-hospital adverse events, and 30-day readmission. RESULTS: 12,063 encounters of patients who underwent SM were included (56.1% isolated SM, 9.0% SM + CABG only, 17.5% SM + MVR, 13.1% SM + SAVR, and 4.3% SM + MVR + SAVR). Patients who underwent isolated SM were younger (54.3 vs. 67.1 years-old, p < 0.01) and had lower overall comorbidity burden. In-hospital mortality was lowest in isolated SM, followed by CABG only, SM + SAVR, SM + MVR, and SM + SAVR+MVR groups (2.3% vs. 3.7% vs. 5.3% vs. 6.7% vs. 13.7%, p < 0.01), respectively. SM with combined surgical interventions was associated with higher adverse in-hospital events (24.3% vs. 11.1%, p < 0.01) and 30-day readmissions (16.9% vs. 10.4%, p < 0.01). MV repair performed concomitantly with SM was not associated with increased in-hospital mortality (3.9% vs. 3.4%, p = 0.72; aOR 0.99; 95% CI: 0.54-1.80, p = 0.97]) or adverse clinical events. CONCLUSIONS: In SM for oHCM, patients undergoing concomitant surgical interventions were characteristically distinct. Aside from MV repair, concomitant interventions were associated with worse in-hospital death, adverse in-hospital events, and 30-day readmission.

Hospital Procedural Volume and Clinical Outcomes Following Septal Reduction Therapy in Obstructive Hypertrophic Cardiomyopathy.

Background Prior national data showed a substantial in-hospital mortality in septal myectomy (SM) with an inverse volume-outcomes relationship. This study sought to assess the contemporary outcomes of septal reduction therapy and volume-outcome relationship in obstructive hypertrophic cardiomyopathy. Methods and Results All septal reduction therapy admissions between 2010 to 2019 in the United States were analyzed using the National Readmission Databases. Hospitals were stratified into tertiles of low-, medium-, and high-volume based on annualized procedural volume of alcohol septal ablation and SM. Of 19 007 patients with obstructive hypertrophic cardiomyopathy who underwent septal reduction therapy, 12 065 (63%) had SM. Two-thirds of hospitals performed ≤5 SM or alcohol septal ablation annually. In all SM encounters, 482 patients (4.0%) died in-hospital post-SM. In-hospital mortality was <1% in 1505 (88.4%) hospitals, 1% to 10% in 30 (1.8%) hospitals, and ≥10% in 167 (9.8%) hospitals. There were 63 (3.7%) hospitals (averaging 2.2 SM cases/year) with 100% in-hospital mortality. Post-SM (in low-, medium-, and high-volume centers, respectively), in-hospital mortality (5.7% versus 3.9% versus 2.4%, P=0.003; adjusted odds ratio [aOR], 2.86 [95% CI, 1.70-4.80], P=0.001), adverse in-hospital events (21.30% versus 18.0% versus 12.6%, P=0.001; aOR, 1.88 [95% CI, 1.45-2.43], P=0.001), and 30-day readmission (17.1% versus 12.9% versus 9.7%, P=0.001; adjusted hazard ratio, 1.53 [95% CI, 1.27-1.96], P=0.001) were significantly higher in low- versus high-volume hospitals. For alcohol septal ablation, the incidence of in-hospital death and all other outcomes did not differ by hospital volume. Conclusions In-hospital SM mortality was 4% with an inverse volume-mortality relationship. Mortality post-alcohol septal ablation was similar across all volume tertiles. Morbidity associated with SM was substantial across all volume tertiles.

Cardiac magnetic resonance for prophylactic implantable-cardioverter defibrillator therapy international study: prognostic value of cardiac magnetic resonance-derived right ventricular parameters substudy.

AIMS: Right ventricular systolic dysfunction (RVSD) is an important determinant of outcomes in heart failure (HF) cohorts. While the quantitative assessment of RV function is challenging using 2D-echocardiography, cardiac magnetic resonance (CMR) is the gold standard with its high spatial resolution and precise anatomical definition. We sought to investigate the prognostic value of CMR-derived RV systolic function in a large cohort of HF with reduced ejection fraction (HFrEF). METHODS AND RESULTS: Study cohort comprised of patients enrolled in the CarDiac MagnEtic Resonance for Primary Prevention Implantable CardioVerter DefibrillAtor ThErapy registry who had HFrEF and had simultaneous baseline CMR and echocardiography (n = 2449). RVSD was defined as RV ejection fraction (RVEF) <45%. Kaplan-Meier curves and cox regression were used to investigate the association between RVSD and all-cause mortality (ACM). Mean age was 59.8 ± 14.0 years, 42.0% were female, and mean left ventricular ejection fraction (LVEF) was 34.0 ± 10.8. Median follow-up was 959 days (interquartile range: 560-1590). RVSD was present in 936 (38.2%) and was an independent predictor of ACM (adjusted hazard ratio = 1.44; 95% CI [1.09-1.91]; P = 0.01). On subgroup analyses, the prognostic value of RVSD was more pronounced in NYHA I/II than in NYHA III/IV, in LVEF <35% than in LVEF ≥35%, and in patients with renal dysfunction when compared to those with normal renal function. CONCLUSION: RV systolic dysfunction is an independent predictor of ACM in HFrEF, with a more pronounced prognostic value in select subgroups, likely reflecting the importance of RVSD in the early stages of HF progression.

Clinical Outcomes of Revascularization with Percutaneous Coronary Intervention Prior to Transcatheter Aortic Valve Replacement: A Comprehensive Meta-Analysis.

BACKGROUND: Prior studies on revascularization prior to transcatheter aortic valve replacement (TAVR), in patients with significant coronary artery disease (CAD), have reported mixed results. AIM: We sought to perform a meta-analysis combining current evidence by investigating outcomes of revascularization in patients who undergo TAVR with coexisting CAD. METHODS: We searched literature for studies reporting on outcomes following TAVR performed with versus without pre-TAVR PCI, for coexisting CAD. Random-effect model was used to pool estimates of odds ratios (ORs). RESULTS: Twenty-four reports with 12,182 TAVR patients were included: 22 observational and 2 clinical trials. 4,110 (33.7%) were in the pre-TAVR PCI group, 51.4% were females, and mean age was 81.9 years. The 30-day mortality was 5.2% versus 5.0% in patients with versus without pre-TAVR PCI, respectively [OR= 1.19 (95% CI: 0.91-1.55, P= 0.20)]. Pooled 1-year mortality was 18.1% versus 19.1% in patients with versus without pre-TAVR PCI (OR= 1.12, 95% CI: 0.95-1.31, P= 0.61). There was no significant difference between the groups for myocardial infarction, stroke, acute kidney injury, pacemaker implantation, or re-hospitalization. Pre-TAVR PCI was associated with an increased risk of life-threatening bleeding at 30 days. CONCLUSION: Pre-TAVR revascularization with PCI was not associated with improved 30-day or 1-year mortality; however, it was associated with an increased risk of life-threatening bleeding at 30-day post-TAVR. Our results do not support routine revascularization with PCI prior to TAVR with coexisting CAD. Future trials addressing anatomical complexity and symptom burden may help better risk stratify patients who may benefit from pre-TAVR revascularization.

Cardiogenic shock in autoimmune rheumatologic diseases: an insight on etiologies, management, and treatment outcomes.

Autoimmune rheumatological disorders are known to have an increased risk for cardiovascular diseases including coronary artery disease (CAD), myocarditis, pericarditis, valvulopathy, and in consequence cardiogenic shock. Data on cardiogenic shock in rheumatological diseases are scarce; however, several reports have highlighted this specific entity. We sought to review the available literature and highlight major outcomes and the management approaches in each disease. Systematic literature search, including PubMed, Ovid/Medline, Cochrane Library, and Web of Science, was conducted between January 2000 and December 2009. We reviewed all cases reporting cardiogenic shock with rheumatologic conditions, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Takayasu's arteritis (TA), granulomatosis with polyangiitis (GPA), giant cell arteritis (GCA), and antiphospholipid syndrome (APS). We selected 45 papers reporting a total of 48 cases. Mean age was 39 ± 7.3 years and 68.8% were females. Most common rheumatologic conditions associated with cardiogenic shock were SLE (31%), GPA (23%), TA (14.6%), APA (10.4%), and RA (8.3%). Cardiogenic shock was found to be caused by eosinophilic myocarditis in 58% of cases, CAD in 19% of cases, and valvulopathy in 6% of cases. Most patient required high-dose steroids and second immunosuppressant therapy. Mechanical circulatory supported was required in 23 cases, IABP in 16 cases, and ECMO in 12 cases. Complete recovery occurred in 37 patients while 9 patients died and 2 required heart transplant. Responsible for two-thirds of cases, eosinophilic myocarditis should be suspected in young cardiogenic shock patients with underlying rheumatologic conditions. Lupus and GPA are the two most common conditions.

Characteristics and comparative clinical outcomes of prisoner versus non-prisoner populations hospitalized with COVID-19.

Prisons in the United States have become a hotbed for spreading COVID-19 among incarcerated individuals. COVID-19 cases among prisoners are on the rise, with more than 143,000 confirmed cases to date. However, there is paucity of data addressing clinical outcomes and mortality in prisoners hospitalized with COVID-19. An observational study of all patients hospitalized with COVID-19 between March 10 and May 10, 2020 at two Henry Ford Health System hospitals in Michigan. Clinical outcomes were compared amongst hospitalized prisoners and non-prisoner patients. The primary outcomes were intubation rates, in-hospital mortality, and 30-day mortality. Multivariable logistic regression and Cox-regression models were used to investigate primary outcomes. Of the 706 hospitalized COVID-19 patients (mean age 66.7 ± 16.1 years, 57% males, and 44% black), 108 were prisoners and 598 were non-prisoners. Compared to non-prisoners, prisoners were more likely to present with fever, tachypnea, hypoxemia, and markedly elevated inflammatory markers. Prisoners were more commonly admitted to the intensive care unit (ICU) (26.9% vs. 18.7%), required vasopressors (24.1% vs. 9.9%), and intubated (25.0% vs. 15.2%). Prisoners had higher unadjusted inpatient mortality (29.6% vs. 20.1%) and 30-day mortality (34.3% vs. 24.6%). In the adjusted models, prisoner status was associated with higher in-hospital death (odds ratio, 2.32; 95% confidence interval (CI), 1.33 to 4.05) and 30-day mortality (hazard ratio, 2.00; 95% CI, 1.33 to 3.00). In this cohort of hospitalized COVID-19 patients, prisoner status was associated with more severe clinical presentation, higher rates of ICU admissions, vasopressors requirement, intubation, in-hospital mortality, and 30-day mortality.

Spontaneous Biliary Pericardial Tamponade: A Case Report and Literature Review.

BACKGROUND: Biliary pericardial tamponade (BPT) is a rare form of pericardial tamponade, characterized by yellowish-greenish pericardial fluid upon pericardiocentesis. Historically, BPT reported to occur in the setting of an associated pericardiobiliary fistula. However, BPT in the absence of a detectable fistula is extremely rare. LEARNING OBJECTIVE: A biliary pericardial tamponade is a rare form of tamponade warranting a prompt workup (e.g., MRCP or HIDA scan) for a potential fistula between the biliary system and the pericardial space. A pericardio-biliary fistula can be iatrogenic or traumatic. People with a history of chest wall trauma, abdominal surgery, or chest surgery are at increased risk. The use of HIDA scanning plays a salient role in effectively surveilling for the presence of a fistula - especially when MRCP is contraindicated. CASE PRESENTATION: A 75-year-old Hispanic male presenting with dyspnea and diagnosed with cardiac tamponade is the subject of the study. Subsequent pericardiocentesis revealed biliary pericardial fluid (bilirubin of 7.6 mg/dl). The patient underwent extensive workup to identify a potential fistula between the hepatobiliary system and the pericardial space, which was non-revealing. The mechanism of bile entry into the pericardial space remains to be unidentified. LITERATURE REVIEW: A total of six previously published BPT were identified: all were males, with a mean age of 53.3 years (range: 31-73). Mortality was reported in two out of the six cases. The underlying etiology for pericardial tamponade varied across the cases: incidental pericardio-biliary fistula, traumatic pericardial injury, and presence of associated malignancy. - Conclusion: Biliary pericardial tamponade is a rare form of tamponade that warrants a prompt workup (e.g., Hepatobiliary Iminodiacetic Acid - HIDA scan) for an iatrogenic vs. traumatic pericardio- biliary fistula. As a first case in the literature, our case exhibits a biliary tamponade in the absence of an identifiable fistula.

Readmission-free period and in-hospital mortality at the time of first readmission in acute heart failure patients-NRD-based analysis of 40,000 heart failure readmissions.

The 30-day readmission rates, predictors, and outcomes for acute heart failure (AHF) patients are well published, but data beyond 30 days and the association between readmission-free period (RFP) and in-hospital readmission-related mortality remain unknown. We queried the National Readmission Database to analyze comparative outcomes of AHF. Patients were divided into three groups based on their RFP: group 1 (1-30 days), group 2 (31-90 days), and group 3 (91-275 days). AHF cases and clinical variables were identified using ICD-9 codes. The primary outcome was in-hospital mortality at the time of readmission. A total of 39,237 unplanned readmissions occurred within 275 days; 15,181 within group 1, 11,925 within group 2, and 12,131 within group 3. In-hospital mortality in groups 1, 2, and 3 were 7.4%, 5.1%, and 4.1% (p < 0.001). Group 1 had higher percentages of patients with cardiogenic shock (1.3% vs. 0.9% vs. 0.9%; p < 0.001), acute kidney injury (30.2% vs. 25.9% vs. 24.0%; p < 0.001), dialysis use (8.6% vs. 7.5% vs. 6.9%; p < 0.001), and non-ST elevation myocardial infarction (4.4% vs. 3.8% vs. 3.6%; p < 0.001), but there was no statistical difference among the three groups for ST-elevation myocardial infarction, percutaneous coronary intervention (PCI), or ventricular assist device use at the time of index admission. However, group 3 had higher PCI (1.7%) compared with groups 1 and 2 (p < 0.001). In multivariable logistic regression, groups 2 and 3 had odd ratio of 0.70 and 0.55, respectively, for in-hospital mortality compared with group 1. Longer RFP is associated with decreased risk of in-hospital mortality at the time of first readmission.

Speckle tracking echocardiography can predict subclinical myocardial involvement in patients with sarcoidosis: A meta-analysis.

BACKGROUND: This meta-analysis aims to evaluate the utility of speckle tracking echocardiography (STE) as a tool to evaluate for cardiac sarcoidosis (CS) early in its course. Electrocardiography and echocardiography have limited sensitivity in this role, while advanced imaging modalities such as cardiac magnetic resonance (CMR) and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) are limited by cost and availability. METHODS: We compiled English language articles that reported left ventricular global longitudinal strain (LVGLS) or global circumferential strain (GCS) in patients with confirmed extra-cardiac sarcoidosis versus healthy controls. Studies that exclusively included patients with probable or definite CS were excluded. Continuous data were pooled as a standard mean difference (SMD), comparing sarcoidosis group with healthy controls. A random-effect model was adopted in all analyses. Heterogeneity was assessed using Q and I2 statistics. RESULTS: Nine studies were included in our final analysis with an aggregate of 967 patients. LVGLS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD -3.98, 95% confidence interval (CI): -5.32, -2.64, P < .001, also was significantly lower in patients who suffered major cardiac events (MCE), -3.89, 95% CI -6.14, -1.64, P < .001. GCS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD: -3.33, 95% CI -4.71, -1.95, P < .001. CONCLUSION: LVGLS and GCS were significantly lower in extra-cardiac sarcoidosis patients despite not exhibiting any cardiac symptoms. LVGLS correlates with MCEs in CS. Further studies are required to investigate the role of STE in the early screening of CS.

Assessment of right ventricular function following left ventricular assist device (LVAD) implantation-The role of speckle-tracking echocardiography: A meta-analysis.

BACKGROUND: Right ventricular failure (RVF) following left ventricular assist device (LVAD) implantation is associated with worse outcomes. Prediction of RVF is difficult with routine transthoracic echocardiography (TTE), while speckle-tracking echocardiography (STE) showed promising results. We performed systematic review and meta-analysis of published literature. METHODS: We queried multiple databases to compile articles reporting preoperative or intraoperative right ventricle global longitudinal strain (RVGLS) or right ventricle free wall strain (RVFWS) in LVAD recipients. The standard mean difference (SMD) in RVGLS and RVFWS in patients with and without RVF postoperatively was pooled using random-effects model. RESULTS: Seventeen studies were included. Patients with RVF had significantly lower RVGLS and RVFWS as compared to non-RVF patients; SMD: 2.79 (95% CI: -4.07 to -1.50; P: <.001) and -3.05 (95% CI: -4.11 to -1.99; P: <.001), respectively. The pooled odds ratio (OR) for RVF per percentage increase of RVGLS and RVFWS were 1.10 (95 CI: 0.98-1.25) and 1.63 (95% CI 1.07-2.47), respectively. In a subgroup analysis, TTE-derived GLS and FWS were significantly lower in RVF patients as compared to non-RVF patients; SMD of -3.97 (95% CI: -5.40 to -2.54; P: <.001) and -3.05 (95% CI: -4.11 to -1.99; P: <.001), respectively. There was no significant difference between RVF and non-RVF groups in TEE-derived RVGLS and RVFWS. CONCLUSION: RVGLS and RVFWS were lower in patients who developed RVF as compared to non-RVF patients. In a subgroup analysis, TTE-derived RVGLS and RVFWS were reduced in RVF patients as compared to non-RVF patients. This difference was not reported with TEE.

Protocol registration issues of systematic review and meta-analysis studies: a survey of global researchers.

BACKGROUND: Although protocol registration of systematic reviews/meta-analysis (SR/MA) is still not mandatory, it is highly recommended that authors publish their SR/MA protocols prior to submitting their manuscripts for publication as recommended by the Cochrane guidelines for conducting SR/MAs. our aim was to assess the awareness, obstacles, and opinions of SR/MA authors about the protocol registration process. METHODS: A cross-sectional survey study included the authors who published SR/MAs during the period from 2010 to 2016, and they were contacted for participation in our survey study. They were identified through the literature search of SR/MAs in Scopus database. An online questionnaire was sent to each participant via e-mail after receiving their approval to join the study. We have sent 6650 emails and received 275 responses. RESULTS: A total of 270 authors responses were complete and included in the final analysis. Our results has shown that PROSPERO was the most common database used for protocol registration (71.3%). The registration-to-acceptance time interval in PROSPERO was less than 1 month (99.1%). Almost half of the authors (44.2%) did not register their protocols prior to publishing their SR/MAs and according to their opinion that the other authors lack knowledge of protocol importance and mandance to be registered, was the most commonly reported reason (44.9%). A significant percenatge of respondents (37.4%) believed that people would steal their ideas from protocol databases, while only 5.3% reported that their SR/MA had been stolen. However, the majority (72.9%) of participants have agreed that protocol registries play a role in preventing unnecessary duplication of reviews. Finally, 37.4% of participants agree that SR/MA protocol registration should be mandatory. CONCLUSION: About half of the participants believes that the main reason for not registering protocols, is that the other authors lack knowledge concerning obligation and importance to register the SR/MA protocols in advance. Therefore, tools should be available to mandate protocol registration of any SRs beforehand and increasing awareness about the benefits of protocol registration among researchers.

Cutaneous Fusariosis in a Patient with Job's (Hyper-IgE) Syndrome.

Fusarium is a filamentous fungus that is ubiquitous in nature and can cause severe opportunistic infections in immunocompromised hosts. The association between Fusarium and hyper-IgE syndrome is exceedingly rare and has only been documented in a single report previously. A 44-year-old male, working as marijuana grower, with prior diagnosis of hyper-IgE syndrome and recurrent infections presented with enlarging right knee ulcer that did not respond to antimicrobial treatment. The patient was diagnosed with cutaneous fusariosis, confirmed with punch biopsy and positive wound cultures. The patient was managed with extended antifungal therapy (i.e., posaconazole) and surgical debridement resulting in remarkable improvement with wound healing leaving a pale scar. Fusarium should be considered in differential for cutaneous and invasive fungal infections in presence of cutaneous manifestations. Exposure to Cannabis plants is a noticeable risk factor. Multimodal approach involving systemic antifungals and wound debridement is essential for favorable outcome. Posaconazole was demonstrated to be a highly efficacious antifungal choice.

The Utility of Intraoperative Lateral Spread Recording in Microvascular Decompression for Hemifacial Spasm: A Systematic Review and Meta-Analysis.

BACKGROUND: Microvascular decompression (MVD) is the surgical treatment of choice for hemifacial spasm (HFS). During MVD, monitoring of the abnormal lateral spread response (LSR), an evoked response to facial nerve stimulation, has been traditionally used to monitor adequacy of cranial nerve (CN) VII decompression. OBJECTIVE: To assess the utility of LSR monitoring in predicting spasm-free status after MVD postoperatively. METHODS: We searched PubMed, Web of Science, and Embase for relevant publications. We included studies reporting on intraoperative LSR monitoring during MVD for HFS and spasm-free status following the procedure. Sensitivity of LSR, specificity, diagnostic odds ratio, and positive predictive value were calculated. RESULTS: From 148 studies, 26 studies with 7479 patients were ultimately included in this meta-analysis. The final intraoperative LSR status predicted the clinical outcome of MVD with the following specificities and sensitivities: 89% (0.83- 0.93) and 40% (0.30- 0.51) at discharge, 90% (0.84-0.94) and 41% (0.29-0.53) at 3 mo, 89% (0.83-0.93) and 40% (0.30-0.51) at 1 yr. When LSR persisted after MVD, the probability (95% CI) for HFS persistence was 47.8% (0.33-0.63) at discharge, 40.8% (0.23-0.61) at 3 mo, and 24.4% (0.13-0.41) at 1 yr. However, when LSR resolved, the probability for HFS persistence was 7.3% at discharge, 4.2% at 3 mo, and 4.0% at 1 yr. CONCLUSION: Intraoperative LSR monitoring has high specificity but modest sensitivity in predicting the spasm-free status following MVD. Persistence of LSR carries high risk for immediate and long-term facial spasm persistence. Therefore, adequacy of decompression should be thoroughly investigated before closing in cases where intraoperative LSR persists.

Correction to: Readmission-free period and in-hospital mortality at the time of first readmission in acute heart failure patients-NRD-based analysis of 40,000 heart failure readmissions.

The original version of this article unfortunately contained a mistake. Unfortunately, the name of one of the authors (Dr. Pradhum Ram) has been misspelled as (Prathaum Ram) instead.
