Stingray Sensor System for Persistent Survey of the GEO Belt. SENSORS (BASEL, SWITZERLAND) 2024; 24:2596. [PMID: 38676213 PMCID: PMC11054799 DOI: 10.3390/s24082596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 03/13/2024] [Accepted: 03/24/2024] [Indexed: 04/28/2024]
Abstract
The Stingray sensor system is a 15-camera optical array dedicated to the nightly astrometric and photometric survey of the geosynchronous Earth orbit (GEO) belt visible above Tucson, Arizona. The primary scientific goal is to characterize GEO and near-GEO satellites based on their observable properties. This system is completely autonomous in both data acquisition and processing, with human oversight reserved for data quality assurance and system maintenance. The 15 ZWO ASI1600MM Pro cameras are mated to Sigma 135 mm f/1.8 lenses and are controlled simultaneously by four separate computers. Each camera is fixed in position and observes a 7.6-by-5.8-degree portion of the GEO belt, for a total of a 114-by-5.8-degree field of regard. The GAIA DR2 star catalog is used for image astrometric plate solution and photometric calibration to GAIA G magnitudes. There are approximately 200 near-GEO satellites on any given night that fall within the Stingray field of regard, and all those with a GAIA G magnitude brighter than approximately 15.5 are measured by the automated data reduction pipeline. Results from an initial one-month survey show an aggregate photometric uncertainty of 0.062 ± 0.008 magnitudes and astrometric accuracy consistent with theoretical sub-pixel centroid limits. Provided in this work is a discussion of the design and function of the system, along with verification of the initial survey results.

Abstract
OBJECTIVE Patients with hearing loss and tinnitus face lengthy waits to be seen in the ENT clinic. SHOEBOX Audiometry is an iPad-based, audiometric screening tool. A virtual hearing loss and non-pulsatile tinnitus clinic involving an ENT specialist virtually assessing cases based on the SHOEBOX audiogram, a patient symptom questionnaire and the primary care referral letter were implemented. This service evaluation explored the outcomes of the virtual clinic in reducing the need for a face-to-face ENT appointment. METHOD This was a retrospective service evaluation of the first six months of the virtual hearing loss and non-pulsatile tinnitus clinic. RESULTS A total of 210 patients were included: 34.8 per cent (73) were discharged without requiring audiologist assessment or an ENT appointment, 51.9 per cent (109) required formal audiological assessment, 36.7 per cent (77) required imaging and only 13.8 per cent (29) required a face-to-face ENT appointment. CONCLUSION A virtual hearing loss and non-pulsatile tinnitus clinic minimised the number of patients requiring a traditional face-to-face clinic appointment within ENT.

Abstract
Large constellations of bright artificial satellites in low Earth orbit pose significant challenges to ground-based astronomy1. Current orbiting constellation satellites have brightnesses between apparent magnitudes 4 and 6, whereas in the near-infrared Ks band, they can reach magnitude 2 (ref. 2). Satellite operators, astronomers and other users of the night sky are working on brightness mitigation strategies3,4. Radio emissions induce further potential risk to ground-based radio telescopes that also need to be evaluated. Here we report the outcome of an international optical observation campaign of a prototype constellation satellite, AST SpaceMobile's BlueWalker 3. BlueWalker 3 features a 64.3 m2 phased-array antenna as well as a launch vehicle adaptor (LVA)5. The peak brightness of the satellite reached an apparent magnitude of 0.4. This made the new satellite one of the brightest objects in the night sky. Additionally, the LVA reached an apparent V-band magnitude of 5.5, four times brighter than the current International Astronomical Union recommendation of magnitude 7 (refs. 3,6); it jettisoned on 10 November 2022 (Universal Time), and its orbital ephemeris was not publicly released until 4 days later. The expected build-out of constellations with hundreds of thousands of new bright objects1 will make active satellite tracking and avoidance strategies a necessity for ground-based telescopes.

Abstract
Abstract
Objectives
In implementing the 2021 CKD-EPI without race equation in our institution, we sought to investigate the differences between the new CKD-EPI equation and the current MDRD equation to assist clinicians in transitioning to the new equation.
Methods
A retrospective study was performed in patients with eGFR<60 ml/min/1.73 m2 calculated by MDRD. Stata was used to analyze the eGFR calculated by the two equations and measure the differences according to respective categories.
Results
eGFRs calculated by the 2021 CKD-EPI without race equation were well correlated to eGFRs calculated by the MDRD. However, notable differences were observed. Compared to the MDRD, the CKD-EPI w/o race equation for Black males with a serum creatinine less than 1.5 yielded decreased eGFR results with mean negative differences of -4.49 (18-60 years old), -6.43 (60-80 years old), and -8.87 (>80 years old). For serum creatinine cohorts between 1.5 to 2.0 and greater than 2.0, the differences were -3.35, -5.46, -7.48 and -1.86, -3.40, -4.14, respectively. A similar trend was noted in Black females. For those with a serum creatinine less than 1.5, the CKD-EPI equation yielded mean negative differences that increased with advancing age: -2.56, -4.74 and -7.27. For serum creatinine between 1.5 to 2.0 and greater than 2.0, the negative differences were -2.31, -3.73 and -5.28 and -1.30, -2.06 and -2.70, respectively. Therefore, in Black patients, the mean eGFR difference between the two equations increased as age increased and serum creatinine level decreased. In contrast, the CKD-EPI equation for White males with a serum creatinine less than 1.5 yielded increased eGFR results with mean positive difference of 7.22 (18-60 years old), 4.09 (60-80 years old), and 1.26 (>80 years old). For serum creatinine cohorts between 1.5 to 2.0 and greater than 2.0, the differences were 5.15, 2.54 and 0.18 and 2.01, 0.69 and -0.15, respectively. Similarly, White females had mean positive differences of 8.09 (18-60 years old), 4.61 (60-80 years old) and 2.00 (>80 years old). For cohorts with serum creatinine between 1.5 to 2.0 and greater than 2.0, the positive differences were 4.21, 2.24, 0.51 and 2.02, 0.82, 0.10. Therefore, in White patients, the difference of eGFR between the two equations increased as age decreased and creatinine level decreased.
Conclusions
Although the 2021 CKD-EPI equation strongly correlated with the MDRD, distinct differences exist. In our study, Black males and females exhibited a negative difference of around -5.0 and -4.0, respectively. The difference in eGFR was greater in those of older age and serum creatinine less than 1.5. Meanwhile, White males and females exhibited a positive difference of around 2.5 and 2.7. The difference in eGFR was greater in those of younger age and serum creatinine less than 1.5.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Therapy-related myeloid neoplasm (t-MN) in the pediatric population is not well characterized. We studied 12 pediatric patients diagnosed with t-MN in our institution since 2006. The median age at the t-MN diagnoses was 14.8 years (range, 9 to 20 y). The primary malignancies included 9 solid tumors and 3 hematopoietic malignancies. Rhabdomyosarcoma (n=4) was the most common primary malignancy. Five of the 9 patients with solid tumors and all 3 patients with hematopoietic malignancies had primary neoplasms involving bone marrow. The median latency period was 5.2 years (range, 1.8 to 13.8 y). Thrombocytopenia was present in all patients at the t-MN diagnoses. Complete or partial monosomy of chromosome 5 or 7 were the 2 most common cytogenetic abnormalities. A quarter of patients demonstrated a genetic predisposition to t-MN: 1 with Li-Fraumeni syndrome with a germline TP53 R248Q mutation, 1 with Noonan syndrome with a somatic mutation (PTPN11 S502T), and 1 with a constitutive chromosomal translocation [t(X;9)(p22;q34)] and a germline TP53 L130V mutation. Outcomes remain poor. Two patients survived 3 and 5.1 years after hematopoietic stem cell transplantation.

Abstract
Abstract
Introduction/Objective
Glomus tumors are mesenchymal neoplasms with glomus body type modified smooth muscle cell differentiation. Most glomus tumors have a benign clinical course. However, rarely, they display malignant histologic features.
Methods/Case Report
We undertook a retrospective study using a natural language search in CoPath to find surgical pathology cases from 1993-2020 containing “glomus” in the pathology diagnosis. All relevant cases were included, and clinicopathologic data were reviewed in detail.
Results (if a Case Study enter NA)
A total of 66 tumors were identified, of which 42 were in female (63.6%) and 24 in male (36.4%) patients. The age at surgery ranged from 22 to 79 years with a median of 47.5. Females were significantly younger than males at presentation (p=0.025) by 8.8±3.8 years. Forty cases (60.6%) were located on the digits, 24 in nonvisceral soft tissue of extremities, trunk, and lip (36.4%), and one each in stomach and breast parenchyma. Sixty-three (95.5%) were benign (of which one recurred locally), 2 (3%) were malignant, and 1 (1.5%) was atypical. Four (6%) were multicentric. One case showed mixed histology (oncocytic and classic features) and one was classified as glomangiomatosis. The malignant cases each presented with a single tumor in lower extremity soft tissue in female patients (aged 33 and 49 years). The tumors measured 0.5 and 1.8 cm respectively and showed marked cytologic atypia in both and increased mitotic activity in the first. They were both completely excised.
Conclusion
The majority of glomus tumors are benign, however 3% are malignant. The most common location is the digits, followed by soft tissue. This tumor is more commonly seen in female patients. Unusual histologic variants such as glomangiomatosis and oncocytic component at times may create some difficulty to reach the diagnosis, especially on small biopsies. Unusual locations such as stomach can lead to a wrong diagnosis such as carcinoid, especially in a small biopsy material.

Abstract
OBJECTIVES To provide an overview of the challenges encountered during the interpretation of sequence variants detected by next-generation sequencing (NGS) in myeloid neoplasms, as well as the limitations of the technology with the goal of preventing the over- or undercalling of alterations that may have a significant effect on patient management. METHODS Review of the peer-reviewed literature on the interpretation, reporting, and technical challenges of NGS assays for myeloid neoplasms. RESULTS NGS has been integrated widely and rapidly into the standard evaluating of myeloid neoplasms. Review of the literature reveals that myeloid sequence variants are challenging to detect and interpret. Large insertions and guanine-cytosine-heavy areas prove technically challenging while frameshift and truncating alterations may be classified as variants of uncertain significance by tertiary analysis informatics pipelines due to their absence in the literature and databases. CONCLUSIONS The analysis and interpretation of NGS results in myeloid neoplasia are challenging due to the varied number of detectable gene alterations. Familiarity with the genomic landscape of myeloid malignancies and knowledge of the tools available for the interpretation of sequence variants are essential to facilitate translation into clinical and therapy decisions.

Abstract
Abstract
Background/Introduction
The inspIRE clinical trial was designed to assess the safety and efficacy of a fully integrated biphasic pulsed field ablation (PFA) system comprised of a multi-channel generator, variable decapolar irrigated loop circular catheter, and mapping system (Figure A) for the treatment of paroxysmal atrial fibrillation (PAF).
Purpose
Using this novel PFA system in a multicentre clinical trial, we present the initial feasibility of electrical pulmonary vein isolation (PVI), procedural performance, and acute safety results.
Methods
inspIRE is a prospective, non-randomized, multi-centre study, planned to enrol up to 550 patients. PVI is performed with the novel, variable loop circular catheter, compatible mapping system and generator. Acute procedural effectiveness (entrance block in all clinically targeted PVs post adenosine/isoproterenol challenge) and the incidence of primary adverse events (PAEs) were assessed. PAEs are defined as the occurrence of cardiac tamponade/perforation, myocardial infarction, stroke/cerebrovascular accident, thromboembolism, transient ischemic attack, permanent phrenic nerve paralysis, pulmonary edema, pericarditis, and any major vascular access complications within 7 days of the ablation procedure. Additionally, any incidence of procedure or device related death, atrio-esophageal fistula, or PV stenosis (related to the ablation procedure or study catheter) within the 12M follow-up period is classified as a PAE.
Results
A total of 35 PAF subjects (age 59.7±10.7 years, 54.3% male) were treated across 5 European sites by 6 operators. Acute procedural success was achieved in 100% of study subjects (Figure B) with zero incidence of PAEs. Mean total procedure time was 82.9±19.9 minutes with 27.0±11.9 minutes of PFA from first to last application. Average fluoroscopy use was 10.6±6.8 minutes and LA dwell time was 45.6±15.3 minutes.
Conclusion
Initial results of the inspIRE trial demonstrate the acute safety and effectiveness of the new integrated IRE circular catheter, mapping system and generator for PVI in PAF patients.

Abstract
The purpose of our study is to highlight the demographic characteristics, pathological features, and clinical course of multiple myeloma (MM) patients with secondary primary malignancies (SPM). A retrospective chart review was performed from January 2009 to February 2020. Patients' demographic, pathologic and cytogenetic features, treatment characteristics and clinical outcomes were collected. We identified 871 MM patients including 40 patients who developed SPM. Among the 40 patients with SPM, 17 patients developed hematological SPM and 23 patients developed solid SPM. The median time from diagnosis of MM to the occurrence of hematological SPM was 6.85 versus 3.91 years in solid SPM, with a median overall survival (OS) after diagnosis of SPM of 120 and 880 days, respectively. Interestingly, we observed that there was no significant difference in OS between MM patients with or without SPM. Multivariable analysis showed that age and autologous stem cell transplantation were independent factors associated with patients' clinical outcomes. Our study highlights the importance of understanding the etiology, biology, clinical outcome and management in MM patients with SPM.

Discordance Between Immunohistochemistry and In Situ Hybridization to Detect HER2 Overexpression/Gene Amplification in Breast Cancer in the Modern Age: A Single Institution Experience and Pooled Literature Review Study. Clin Breast Cancer 2021; 22:e123-e133.

Abstract
BACKGROUND Human epidermal growth factor 2 (HER2) amplification and/or overexpression occurs in 12% to 25% of breast cancers. Accurate detection of HER2 is critical in predicting response to HER2-targeted therapy. Both immunohistochemistry (IHC) and in situ hybridization (ISH) are FDA-approved methods for detecting HER2 status because its protein overexpression is largely attributable to gene amplification. However, variable discordant results between IHC and ISH have been reported. METHODS We determined the frequency of HER2 IHC/ISH discordance in these patients and also performed a pooled literature review analysis. RESULTS Of the 1125 consecutive primary or metastatic breast cancers with HER2 IHC and ISH performed simultaneously between 2015 and 2020, 84.6% had an unequivocal HER2 status. Discordance was found in 30 cases from 26 patients, including 13 IHC-/ISH+ and 17 IHC+/ISH-, representing 1.6% and 11.9% of IHC- and IHC+ cases, respectively. Review of the literature between 2001 and 2020 identified 46 relevant studies, with a total of 43,468 cases with IHC and ISH performed. The IHC-/ISH+ and IHC+/ISH- discordances were seen in all antibody clones and ISH methods used. The IHC+/ISH- discordance was significantly higher than IHC-/ISH+ (13.8% vs. 3%, P < .0001). The overall discordance constituted 4% of all cases and 5.4% of those with an unequivocal IHC status. Significantly lower incongruities for both IHC-/ISH+ and IHC+/ISH- were found in those published after 2018. The discordances probably reflect altered biology of HER2 oncogene/oncoprotein. Routinely performing both IHC and ISH may uncover such cases to prevent denial of potentially beneficial targeted therapy.

Abstract
EBV positive mucocutaneous ulcer (EBVMCU) is a newly recognized clinicopathologic entity in the 2017 World Health Organization (WHO) classification. Patients frequently present with an isolated ulcerative lesion in mucosal and cutaneous sites with immunosuppression as the main risk factor. The disease typically follows an indolent clinical course. Herein we describe a series of three patients diagnosed with EBVMCU. Histopathologic examination of these cases shows ulceration in mucosal or cutaneous surface with a substantial number of large atypical transformed cells in the background of dense polymorphous infiltrates. One patient regressed spontaneously with no treatment, one patient needed Rutiximab, and one patient had persistent EBVMCU process with possible transformation to large B cell lymphoma. The aim of the present case series is to highlight the pathologic, diagnostic and clinical features of patients with EBVMCU.

Abstract
Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare primary and highly aggressive intestinal T-cell lymphoma derived from intraepithelial lymphocytes. MEITL is previously designated as type II enteropathy-associated T cell lymphoma (EATL). Unlike to classic form of EATL, MEITL is not associated with celiac disease. The diagnosis of MEITL is very challenging and the clinical outcome of patients with MEITL is very poor. Herein we describe a series of four patients diagnosed with MEITL identified upon a 10-year institutional retrospective review. Histopathologic examination of these cases revealed monotonous population of medium sized cells infiltrating intestinal mucosa, positive for CD3, CD8 and CD56 in all four cases. Two patients had the combination chemotherapy; however, the average survival time was only 7.5 months for these two patients after diagnosis. The aim of the present case series is to highlight the pathology, diagnosis and clinical course of the patients with MEITL based on the current literature.

Abstract
Abstract
Introduction/Objective
The incidence of patients with multiple myeloma (MM) followed by hematologic malignancies as second primary malignancy is around 0.8 – 3.1%. The majority of cases are myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), however, acute lymphoblastic or mixed phenotype leukemia can be rarely observed.
Methods
A retrospective chart review was performed for patients diagnosed with acute lymphoblastic or mixed phenotype leukemia from January 2009 through February 2020. Two patients were identified and the corresponding clinical data were reviewed.
Results
Case 1 was a 74-year old male diagnosed with pre-B ALL 5 years after an IgG Lambda MM. His MM therapy included Bortezomib-based chemotherapy followed by Lenalidomide maintenance. Pre-B diagnosis was confirmed on a pelvic lesion biopsy with sheets of intermediate sized cells (CD45+, PAX5+, CD34+, CD43+, CD10+, BCL6+ and BCL2+). The patient had 4 cycles of HyperCVAD chemotherapy, followed by Blinatumomab and Inotuzumab treatment. Unfortunately, the patient was referred to hospice 2 years after the diagnosis of ALL. Case 2 was a 69-year old male diagnosed with mixed phenotype acute leukemia 8 years after an lgA Lambda MM with del 13q and Trisomy 11. The patient was treated with Bortezomib-based chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) and Lenalidomide maintenance. Bone marrow biopsy showed around 79% blasts (CD34+, PAX-5+, CD79a+ and MPO+). Flow cytometry from bone marrow showed 90% precursor B cells, however MPO was negative. Furthermore, a DNTM3A p.T835M missense variant (25-30% fraction) was identified by next generation sequencing (NGS). The patient was scheduled for Hyper-CVAD chemotherapy.
Conclusion
Lenalidomide maintenance following auto-HSCT is considered a standard therapy for MM patients. Recent studies indicate that Lenalidomide maintenance is associated with an increased risk of second primary hematologic malignancies. Although AML and MDS are more commonly seen, ALL and rarely mixed phenotype leukemias can occur.

Abstract
We report, to the best of our best knowledge, the oldest individual to ever be diagnosed with Familial Hemophagocytic Lymphohistiocytosis (FHL) Type 2 from homozygous c.1349C>T (p.T450M) missense variants in the PRF1 gene. This rare case advanced in complexity with a simultaneous diagnosis of Chronic Active Epstein-Barr Virus (CAEBV) - a distinct clinical entity from acute EBV infections and a well-described trigger of Hemophagocytic Lymphohistiocytosis (HLH). This is, to the best of our knowledge, the only individual to ever be diagnosed with CAEBV in the setting of this specific variant and the oldest to be diagnosed with a coexisting perforin variant. This case provides understanding of EBV, human genetics, and lymphoproliferative disorders while adding a unique differential diagnosis to adults who present with fever of unknown origin and diffuse lymphadenopathy without evidence of malignancy. This report explores the diagnosis and treatment of both HLH and CAEBV, encouraging discussion regarding current clinical management and future research needs.

WiSE-CRT and LV-SELECT study and POST-M REGISTRY
Background
The WiSE-CRT (Wireless stimulation endocardial) system has advantages over conventional epicardial CRT. Whenever conventional CRT failed to implant or failed to echocardiographic response, the WiSE-CRT was implanted as part of the WiSE CRT study (N = 13), as part of the LV-SELECT study (N = 35) or as part of the POST-M REGISTRY (N = 117) over the last 8 years. All these studies have reported high rates of clinical and echocardiographic response compared to conventional CRT.
Objectives
The purpose of this analysis was to determine the safety and clinical response in the largest available number of implanted patients (pts) with long term follow up of 2 years and the first, second and third generation of WiSE-CRT devices.
Method
All pts undergoing a WiSE-CRT implantation as part of the WiSE CRT study (N = 13), as part of the LV-SELECT study (N = 35) or as part of the POST-M REGISTRY (N = 117) were analysed (N = 165). Pts were followed-up for 24 months and considered CRT responders if an improvement in NYHA ≥ 1 class from baseline (pre-implant) was achieved.
Results
In total, 165 pts were implanted, demographics include: 68.2 ± 9.6 year’s old, 81.8% male, 49.7% with history of AFib and 54.5% non-ischaemic aetiology. The mean intrinsic QRS duration was 165.0 ± 32.3 msec (28 pts pace-maker dependent). 161 pts had the system successfully implanted with no major complications, 3 (1.8%) pts developed a pericardial effusion and 1 (0.6%) electrode was lost during implantation and recovered surgically. During the 24-month follow-up period, 20 (12.1%) pts died from any cause, 4 (2.4%) pts developed TIA or Stroke and 15 (9.1%) pts had pocket or transmitter infection. There was a significant improvement in NYHA functional class in 63.6% pts and an average improvement of -26.1 (-45.1, -7.1) msec in QRS duration.
Conclusion
Despite a history of failed conventional CRT implantation, pts undergoing CRT upgrades with a WiSE-CRT have a high success rate and a complication rate similar to previously described. In addition endocardial LV pacing led to symptomatic improvements in 64% of patients reaching the 24 month of follow up.

Abstract
Abstract
Background
Silent cerebral lesions (SCL) often occur after invasive cardiac procedures. Reported SCL incidence with AF ablation varies (incidence, up to 50%), depending on technology used, procedural workflow, and detection method.
Objective
To evaluate the impact of ablation workflow modifications on SCL incidence following pulmonary vein isolation radiofrequency (RF) ablation with a novel multi-electrode RF balloon catheter in patients with symptomatic paroxysmal AF (PAF).
Methods
In the RADIANCE feasibility study of the balloon catheter, all enrolled patients who underwent ablation were screened for SCL using pre- and post-procedural diffusion-weighted MRI. Several modifications were made to the ablation workflow in a subsequent European registration study (SHINE) of the same catheter: eliminating dual transseptal access, using an over-the-wire mini lasso, continuously irrigating all side ports, bolus dosing with heparin before transseptal puncture, maintaining activated clotting time (ACT) at 350–400 sec, and setting a maximum temperature limit of 55°C (previously, 60–65°C). Interim data are presented for SHINE (data cutoff, 22 Oct 2018).
Results
In the neurological assessment evaluable (NAE) populations of RADIANCE (n=38) and SHINE (n=30), respectively, mean ages were 60.8±10.04 and 59.7±7.83 years, and 57.9% and 70.0% were male. One patient in each study had a history of TIAs. SCL incidences were 23.7% (10 lesions in 9 patients) in RADIANCE and 7.1% (2 lesions in 2 patients) in SHINE (excluding 1 SCL that occurred in a patient who failed to meet inclusion criteria [age>75] and 1 SCL that occurred after data cut-off). SHINE NAE enrollment has since completed with no further SCL occurrences. Overall, mean ACTs were 344.3±24.55 sec in RADIANCE and 381.6±73.31 sec in SHINE (p=0.01); in patients with SCL, mean ACTs were 349.3±25.65 and 417.8±87.33 sec, respectively.
Conclusion(s)
Modifications to the workflow led to a decrease in the SCL incidence for PAF ablation using the novel RF balloon catheter.

Abstract
We present a case of chronic myelomonocytic leukemia (CMML) associated with myeloid sarcomas. The CMML also harbored a NPM1 mutation, which is uncommonly described outside the context of acute myeloid leukemia (AML). We describe our treatment strategy, which involved remission-induction chemotherapy that led to rapid resolution of myeloid sarcomas, and we present a literature review highlighting the treatment challenges that similar cases pose.

Abstract
Primary bone marrow diffuse large B-cell lymphoma (BM-DLBCL) is uncommon, with prior reports largely limited to small case series. Here we report the case of a patient who presented with neurologic deficits consistent with acute transverse myelitis and was found to have DLBCL isolated to the bone marrow. We follow this case with a review of the literature summarizing 107 reported cases of BM-DLBCL. Consistent with our case, literature review indicates that BM-DLBCL is characterized by (1) frequent presentation with cytopenias and B symptoms (2) predominant non-germinal center phenotype and (3) aggressive disease with high International Prognostic Index score and low overall survival, with a median survival of 10.0 months in our cohort.

Abstract
OBJECTIVES To assess bone marrow (BM) sampling in academic medical centers. METHODS Data from 6,374 BM samples obtained in 32 centers in 2001 and 2011, including core length (CL), were analyzed. RESULTS BM included a biopsy (BMB; 93%) specimen, aspirate (BMA; 92%) specimen, or both (83%). The median (SD) CL was 12 (8.5) mm, and evaluable marrow was 9 (7.6) mm. Tissue contraction due to processing was 15%. BMB specimens were longer in adults younger than 60 years, men, and bilateral, staging, and baseline samples. Only 4% of BMB and 2% of BMB/BMA samples were deemed inadequate for diagnosis. BM for plasma cell dyscrasias, nonphysician operators, and ancillary studies usage increased, while bilateral sampling decreased over the decade. BM-related quality assurance programs are infrequent. CONCLUSIONS CL is shorter than recommended and varies with patient age and sex, clinical circumstances, and center experience. While pathologists render diagnoses on most cases irrespective of CL, BMB yield improvement is desirable.

Abstract
Diuretics are the mainstay of treatment of refractory heart failure. There is a high incidence of dyselectrolytemia and suboptimal response due to diuretic resistance. Ultrafiltration by peritoneal route can be a safe and effective alternative. This study aims to study the ultrafiltration by peritoneal route in refractory heart failure patients with respect to change in functional status, renal parameters, left ventricular ejection fraction, number of days of hospitalization, and level of myocardial depressant factors. This was a prospective observational study conducted in Nephrology Department of tertiary care hospital. We studied patients with refractory heart failure who had persistent symptoms requiring frequent admissions despite optimal medical decongestion or had dyselectrolytemia with worsening renal parameters. The data were collected at baseline and then after 6 months of starting ultrafiltration. A total of 30 participants were studied. All the patients were in NYHA functional status Class IV before peritoneal ultrafiltration. There was a significant improvement in functional status and only 14 patients (46%) had Class III to Class IV status after application of ultrafiltration. (P < 0.001) There was a significant improvement in duration of hospital stay (75.8 ± 43.3 days to 7.8 ± 12.4, P > 0.001), serum creatinine (3.18 ± 0.98 to 2.16 ± 0.79 mg/dl, P < 0.001), and left ventricular ejection fraction [29.3 ± 7.4 (%) to 48.5 ± 11.8 (%), P < 0.0001] post ultrafiltration. There was also significant improvement in level of myocardial depressant factors (IL-1, IL-6, TNF alpha). Ultrafiltration by peritoneal route seems to be an effective alternative and should be offered to patients with chronic heart failure who are symptomatic despite maximal medical treatment.

Abstract
Myeloproliferative neoplasms (MPNs) are a group of heterogeneous disorders of the hematopoietic system that include myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET). PV and ET are characterized by significant thrombohemorrhagic complications and a high risk of transformation to MF and acute myeloid leukemia. The diagnosis and management of PV and ET has evolved since the identification of mutations implicated in their pathogenesis. These NCCN Guideline Insights discuss the recommendations outlined in the NCCN Guidelines for the risk stratification, treatment, and special considerations for the management of PV and ET.
