Subclinical imaging changes in cerebral cavernous angiomas during prospective surveillance

OBJECTIVEThe purpose of this study was to systematically assess asymptomatic changes (ACs), including subclinical hemorrhage, growth, or new lesion formation (NLF) during longitudinal follow-up of cerebral cavernous angiomas (CAs), and to correlate these with symptomatic hemorrhage (SH) during the same period and with clinical features of the disease.METHODSOne hundred ninety-two patients were included in this study, among 327 consecutive patients with CA, prospectively identified between September 2009 and February 2019. Included patients had undergone clinical and MRI follow-up, in conjunction with institutional review board–approved biomarker studies, and harbored ≥ 1 CA with a maximum diameter of ≥ 5 mm on T2-weighted MRI. Rates of AC and SH per lesion-year and patient-year were assessed using prospectively articulated criteria. In multifocal/familial cases, rates of NLF were also assessed.RESULTSThere were no differences in demographic or disease features among cases included or excluded in the study cohort, except for a higher proportion of included patients with CCM3 mutation. Follow-up was 411 patient-years (2503 lesion-years). The rate of AC was higher than the rate of SH (12.9% vs 7.5% per patient-year, and 2.1% vs 1.2% per lesion-year, both p = 0.02). Patients presenting with a prior history of SH had a higher rate of AC than those with other forms of presentation (19.7% and 8.2% per patient-year, respectively; p = 0.003). A higher rate of NLF on T2-weighted MRI (p = 0.03) was observed in patients with prior SH. Three of 6 solitary/sporadic and 2 of 28 multifocal/familial patients underwent resection of the lesion after AC.CONCLUSIONSRates of AC are greater than SH during prospective follow-up of CAs, and greater in cases with prior SH. AC may be a more sensitive biomarker of lesional activity, and a more efficient surrogate outcome in clinical trials than SH. Patients experiencing an AC are more likely to undergo a surgical intervention when CAs are solitary/sporadic than when they are multifocal/familial.

Introduction: Patients undergoing typical atrial flutter (AFL) ablation remain at risk of developing atrial fibrillation (AF). However, it is unknown whether common risk factors associated with AF occurrence, particularly race, bear out in this population. Hypothesis: We sought to compare the occurrence of new AF in male veteran African-American (AA) and Caucasian (Cau) patients with AFL following successful cavo-tricuspid isthmus ablation. Methods: A retrospective review of patients undergoing AFL ablation between 2002 and 2019 was performed. Patients with prior history of AF were excluded. Records were reviewed and demographics, comorbidities and post-ablation outcomes including new AF and stroke were recorded. The overall incidence of AF and cases per 1000 person-years (CPTPY) were determined. Results: The study cohort comprised 217 patients (age: 66±9.3 years, AA: 97 [45%], Cau:108 [50%]; see Table) with a mean follow-up of 55±42 months after AFL ablation. New AF was detected in 30 (31%) AA and 45 (42%) Cau patients (p=0.21 by Log Rank test). Overall incidence of AF was 78 CPTPY (67 and 91 CPTPY cases in AA and Cau patients, respectively). Time to occurrence of AF was earlier in Cau than AA patients (p=<0.001). New stroke events occurred in 9 (4.4%) patients (4 AA, 5 Cau; p=0.86). Conclusions: Male AA and Cau patients have similar significant risks for developing AF and experiencing stroke after AFL ablation.

OBJECTIVE The objective of this study was to identify the natural history and clinical predictors of postoperative recurrence of skull base and non–skull base meningiomas. METHODS The authors performed a retrospective hospital-based study of all patients with meningioma referred to their institution from September 1993 to January 2014. The cohort constituted both patients with a first-time presentation and those with evidence of recurrence. Kaplan-Meier curves were constructed for analysis of recurrence and differences were assessed using the log-rank test. Cox proportional hazard regression was used to identify potential predictors of recurrence. RESULTS Overall, 398 intracranial meningiomas were reviewed, including 269 (68%) non–skull base and 129 (32%) skull base meningiomas (median follow-up 30.2 months, interquartile range [IQR] 8.5–76 months). The 10-year recurrence-free survival rates for patients with gross-total resection (GTR) and subtotal resection (STR) were 90% and 43%, respectively. Skull base tumors were associated with a lower proliferation index (0.041 vs 0.062, p = 0.001), higher likelihood of WHO Grade I (85.3% vs 69.1%, p = 0.003), and younger patient age (55.2 vs 58.3 years, p = 0.01). Meningiomas in all locations demonstrated an average recurrence rate of 30% at 100 months of follow-up. Subsequently, the recurrence of skull base meningiomas plateaued whereas non–skull base lesions had an 80% recurrence rate at 230 months follow-up (p = 0.02). On univariate analysis, a prior history of recurrence (p < 0.001), initial WHO grade following resection (p < 0.001), and the inability to obtain GTR (p < 0.001) were predictors of future recurrence. On multivariate analysis a prior history of recurrence (p = 0.02) and an STR (p < 0.01) were independent predictors of a recurrence. Assessing only patients with primary presentations, STR and WHO Grades II and III were independent predictors of recurrence (p < 0.001 for both). CONCLUSIONS Patients with skull base meningiomas present at a younger age and have less aggressive lesions overall. Extent of resection is a key predictor of recurrence and long-term follow-up of meningiomas is necessary, especially for non–skull base tumors. In skull base meningiomas, recurrence risk plateaus approximately 100 months after surgery, suggesting that for this specific cohort, follow-up after 100 months can be less frequent.

Background: Overweight and obese adults living with heart failure (HF) have lower mortality compared to those of normal weight. However, the specific relationships of overall weight status and central adiposity with mortality among those with HF are less well-defined. We examined the relationships among body mass index (BMI), waist circumference (WC) and mortality among patients hospitalized for HF in the REGARDS Study. Methods: REGARDS is a national cohort of US community-dwelling adults aged >45 recruited from 2003 to 2007. We measured all-cause mortality rates among 565 participants hospitalized with HF who were normal weight (BMI 18.5-24.9 kg/m 2 ), overweight (BMI 25.0-29.9 kg/m 2 ), or obese (BMI > 30.0 kg/m 2 ) at baseline. Underweight participants (BMI < 18.5 kg/m 2 ) were excluded. Baseline WC, weight, and height were measured during an in-home exam. Index HF hospitalizations during follow-up were adjudicated by a panel of experts. Vital status was determined using the Social Security Death Index or the National Death Index. Cox proportional models estimated hazard ratios for all-cause mortality following the index HF hospitalization. Models were sequentially adjusted for WC, sociodemographics, HF severity (EF and BNP during HF hospitalization, prior history of HF, prior history of diastolic dysfunction), comorbidities, and health behaviors. Results: Among 565 participants hospitalized for HF, 116 (21%) were normal weight, 209 (37%) overweight, and 240 (42%) obese at baseline. Over a mean follow-up of 2.5 years, 253 deaths occurred. In multivariable analyses, overweight was associated with lower all-cause mortality in all models (Table). Each 1-cm increase in WC was associated with higher risk of all-cause mortality, but the relationship was not statistically significant after health behaviors were added in the final model. . Conclusions: Among adults hospitalized for HF, overweight as assessed by BMI may be associated with lower risk for mortality. However, central adiposity may confer higher risk of mortality.

OBJECT Neuroophthalmological morbidity is commonly associated with large and giant cavernous and supraclinoid internal carotid artery (ICA) aneurysms. The authors sought to evaluate the neuroophthalmological outcomes after treatment of these aneurysms with the Pipeline Embolization Device (PED). METHODS The Pipeline for Uncoilable or Failed Aneurysms (PUFS) trial was an international, multicenter prospective trial evaluating the safety and efficacy of the PED. All patients underwent complete neuroophthalmological examinations both before the PED procedure and at a 6-month follow-up. All examinations were performed for the purpose of this study and according to study criteria. RESULTS In total, 108 patients were treated in the PUFS trial, 98 of whom had complete neuroophthalmological follow-up. Of the patients with complete follow-up, 39 (40%) presented with a neuroophthalmological baseline deficit that was presumed to be attributable to the aneurysm, and patients with these baseline deficits had significantly larger aneurysms. In 25 of these patients (64%), the baseline deficit showed at least some improvement 6 months after PED treatment, whereas in 1 patient (2.6%), the deficits only worsened. In 5 patients (5%), new deficits had developed at the 6-month follow-up, while in another 6 patients (6%), deficits that were not originally assumed to be related to the aneurysm had improved by that time. A history of diabetes was associated with failure of the baseline deficits to improve after the treatment. The aneurysm maximum diameter was significantly larger in patients with a new deficit or a worse baseline deficit at 6 months postprocedure. CONCLUSIONS Patients treated with the PED for large and giant ICA aneurysms had excellent neuroophthalmological outcomes 6 months after the procedure, with deficits improving in most of the patients, very few deficits worsening, and few new deficits developing.

Purpose To evaluate treatment patterns in patients diagnosed with incident chronic myelogenous leukemia (CML) newly initiating therapy with imatinib, dasatinib, or nilotinib. Patients were followed to determine switching and discontinuation rates. Factors associated with switching or discontinuation from index TKI therapy, reasons for discontinuation based on electronic chart notes, and frequency of laboratory monitoring were assessed during the follow-up period. Methods A retrospective cohort study was conducted in chronic myelogenous leukemia patients aged ≥ 18 years who were identified from the Kaiser Permanente Southern California (KPSC) Cancer Registry database during the study time period of 1 January 2007 to 12 December 2013. The index date was defined as the date of the first TKI prescription (imatinib, dasatinib, or nilotinib) identified during the study time period with no prior history of TKI use within 12 months. Patients had to have continuous membership with drug benefit eligibility and no prior history of stem cell transplant (SCT) or other cancers during the 12 months prior to the index date. Baseline characteristics were identified during 12 months prior to the index date and outcomes were identified during the follow-up period after the index date. All patients were followed from index TKI therapy until end of study time period (12 December 2014), death, stem cell transplant, or disenrollment from the health plan unless one of the following occurred first: a patient switched their index therapy, or a patient discontinued their index therapy. Forward stepwise selection multivariable logistic regression models were used to evaluate factors associated with patients who continued therapy compared to those who switched or discontinued therapy with the index TKI. Chart notes were reviewed 30 days prior and 30 days post index TKI discontinuation to evaluate reasons for discontinuation. Molecular and cytogenetic testing frequency was also assessed during the follow-up period among the different patient groups. Results Two hundred sixteen patients were identified with incident chronic myelogenous leukemia and use of TKI therapy: 189 (87.5%) received imatinib, 19 (8.8%) received dasatinib, and 8 (3.7%) received nilotinib. The mean age on index date was 53 years and 63% were male; 103 patients (48%) continued on their index therapy, while 62 patients (28%) switched, and 51 patients (24%) discontinued.

Introduction: Certain patient demographics and biomarkers have been shown to predict survival in patients infected with COVID-19. However, predictors of outcome in patients who are critically ill and require advanced respiratory support are unclear. Methods: We performed a multicenter analysis of 159 consecutive patients with confirmed COVID-19 who were admitted to Intensive Care Unit (ICU) between March 01, 2020 and April 30, 2020. Patients were then followed until May 23, 2020. Demographic data (age, sex, race, BMI) and past medical history (hypertension, diabetes, COPD, CKD, history of cardiac ischemic disease, atrial fibrillation and heart failure) were recorded. Laboratory values (troponin, CPK, pro-BNP, ferritin, LDH and d-dimer) were analyzed. Patient status was classified as either alive or deceased at hospital discharge or the end of follow up period. Results: Mean patient age was 66+/-15 and 53% were male. Mean BMI was 31+/- 9. Mean hospital ICU stay was 11+/-8 days. Mortality rate of this ICU cohort at the end of follow-up was 63%. Fifty-five (34%) patients were discharged from the hospital. A multivariable logistic regression analysis identified four factors (age, prior history of diabetes, prior history of atrial fibrillation and elevated troponin) that had significant and independent contributions to the likelihood of survival. Each increase in decade of age above 40 (p = 0.010) was predicted to reduce survival by 30%, the presence of diabetes (p = 0.041) by 57%, a prior history of atrial fibrillation (p= 0.011) by 75%, and each increase of 0.1 ng/mL of troponin above 0.05 ng/ml (p = 0.001) by 55%. Conclusion: Mortality of critically ill COVID-19 patients is high. Early aggressive treatment of high-risk patients identified in this study (advanced age, history of diabetes and atrial fibrillation and elevated troponin) could improve clinical outcome. The highly predictive value of elevated troponin levels on survival may indicate cardiac involvement of COVID-19 infection as a determinant of mortality. Additionally, of available published literature at this time, this is the first study that suggests a relationship between atrial fibrillation and increased mortality from COVID-19. Larger studies are needed to confirm these findings.

Abstract Objective We sought to determine if there is an association between fibroblast growth factor 21 (FGF21) levels and a history of gestational diabetes mellitus (GDM) in women with and without metabolic dysfunction, defined as a diagnosis of metabolic syndrome or type 2 diabetes (T2DM), 5 to 10 years following participation in a multiple cohort GDM study. Study Design At 5 to 10 years after index pregnancy, women underwent a follow-up visit and were categorized as having no metabolic syndrome, metabolic syndrome, or T2DM. FGF21 levels were compared between women who did and did not have a history of GDM using multivariable linear regression. Results Among 1,889 women, 950 underwent follow-up and 796 had plasma samples analyzed (413 GDM and 383 non-GDM). Total 30.7% of women had been diagnosed with T2DM or metabolic syndrome. Overall, there was no difference in median FGF21 levels in pg/mL between the prior GDM and non-GDM groups (p = 0.12), and the lack of association was observed across all three metabolic categories at follow-up (p for interaction = 0.70). Conclusion There was no association between FGF21 levels and prior history of mild GDM in women with and without metabolic dysfunction 5 to 10 years after the index pregnancy (ClinicalTrials.gov number, NCT00069576, original trial).

Tularaemia is a rare infectious disease endemic in most European countries caused by the bacterium Francisella tularensis. 1 Patients often show acute non-specific symptoms, which causes a delay in diagnosis and proper treatment, potentially resulting in significant morbidities such as deep neck abscess, meningitis, endocarditis and septic shock. The authors present a case of a 5-year old boy with a 4-day history of fever, sore throat and painful cervical lymphadenopathy, whose clinical progression worsened despite being treated with recommended antibiotics as per WHO guidelines once the diagnosis of Tularaemia was confirmed by serologic tests. He developed a parapharyngeal abscess and a persistent left necrotic cervical lymph node, which both were surgically drained and excised, respectively, and an extended course of antibiotic was given. Subsequently, the patient fully recovered from the illness and the follow-up was negative for relapse.

Objectives: Among patients treated non-operatively for 1 year following a diagnosis of posterior shoulder instability (PSI), little is known about the the incidence of surgery between 1-13 years after injury. The purpose of this study is to define the frequency and evaluate the factors predictive for late surgical intervention of symptomatic PSI. Methods: This study included a population-based cohort of 115 patients (14 females, 101 males) diagnosed with PSI between January 1994 and July 2012 with a minimum 5-years follow-up (mean:13.9 years; range: 5-23 years). Landmark survival analysis was performed to evaluate incidence of surgery after 1 year. Survival was estimated using Kaplan Meier method and predictors of late surgical intervention were analyzed using Cox proportional hazards regression. Results: A total of 61/115 (53%) patients were treated non-operatively for 1 year following diagnosis of PSI. Of these, 24/61 (39%) converted to surgery for symptomatic PSI. The overall survival free of surgery at 1 and 5 years was 53.0% (95% CI 434.7-63.0) and 37.1% (95% CI 29.1-47.1), respectively. BMI >35 (p=0.04, HR 3.3) was predictive for late conversion to surgery. Age, gender, occupation, or history of glenohumeral dislocation were not significant. Assessing surgery as a time dependent covariate, a patient undergoing surgery was at an increased risk for radiographic progression of osteoarthritis (p=0.02, HR=4.0, 95% CI 1.2-13.2). Conclusion: Conservative management was performed for at least one year in over half of patients diagnosed with PSI. However, long-term follow-up demonstrates that nearly 40% of these patients eventually require surgery. Increased BMI was predictive for late failure of while age, gender, history of dislocation and occupation did not show an effect. Patients who underwent surgery were at an increased risk of radiographic progression of arthritis.

BackgroundThere are few data in the literature on the characteristics and natural history of intracranial arterial infundibular dilatations in children.MethodsAn institutional review board-approved retrospective review was performed of infundibula reported on MR angiography in patients <18 years of age at our tertiary pediatric institute from 1998 to 2016. Clinical data (age, sex, diagnosis, other vascular variants/pathologies) were recorded and images assessed for vessel of origin, infundibulum size and exact location. Ratios of infundibulum:parent artery were assessed at diagnosis and last follow-up. Temporal evolution to aneurysm was evaluated.ResultsWe found 60 intracranial infundibula in 60 children (male:female=27:33; mean age 9.7±5.2 years, range 2–18 years,). Family history of aneurysms was present in 2/60 (3.3%). Syndromic association was found in 14/60 (23.3%), most frequently sickle cell disease (4/14=28.6%). Mean infundibulum size was 2.2±0.5 mm, with mean ratio to parent artery of 0.54±0.17. The most common location was on the P1-posterior cerebral artery (34/63=56.7%), whereas posterior communicating infundibula were seen in only 4/60 (6.7%) cases. Other cerebrovascular variants were seen in 12/60 (20%) patients. On follow-up imaging (in 32/60 patients over 86 patient-years, mean 32.3±35.7 months), no significant change in infundibulum:parent artery ratio was noted. None of the infundibular dilatations showed interval evolution to aneurysm.ConclusionWe present the largest reported cohort of pediatric intracranial arterial infundibula, which we found to be distinct from their adult counterparts with regard to location, etiology and temporal evolution. Growth over time and/or aneurysmal formation are rare, not necessitating frequent short-term imaging surveillance during childhood.
