Biallelic disruption of DDX41 activity is associated with distinct genomic and immunophenotypic hallmarks in acute leukemia. Front Oncol 2023; 13:1153082. [PMID: 37434984 PMCID: PMC10331015 DOI: 10.3389/fonc.2023.1153082] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Accepted: 03/20/2023] [Indexed: 07/13/2023] Open
Abstract
Introduction Inherited DDX41 mutations cause familial predisposition to hematologic malignancies including acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), with the majority of DDX41 mutated MDS/AMLs described to date harboring germline DDX41 and co-occurring somatic DDX41 variants. DDX41-AMLs were shown to share distinguishing clinical features such as a late AML onset and an indolent disease associated with a favorable outcome. However, genotype-phenotype correlation in DDX41-MDS/AMLs remain poorly understood. Methods Here, we studied the genetic profile, bone marrow morphology and immunophenotype of 51 patients with DDX41 mutations. We further assessed the functional impact of ten previously uncharacterized DDX41 variants of uncertain significance. Results Our results demonstrate that MDS/AML cases harboring two DDX41 variants share specific clinicopathologic hallmarks that are not seen in other patients with monoallelic DDX41 related hematologic malignancies. We further showed that the features seen in these individuals with two DDX41 variants were concordant with biallelic DDX41 disruption. Discussion Here, we expand on previous clinicopathologic findings on DDX41 mutated hematologic malignancies. Functional analyses conducted in this study unraveled previously uncharacterized DDX41 alleles and further illustrate the implication of biallelic disruption in the pathophysiology of this distinct AML entity.

Abstract
INTRODUCTION Care for patients with acute myeloid leukemia (AML) is centralized in the Ontario single-payer public healthcare system, with intensive induction chemotherapy and clinical trials only offered at specialized cancer centers with large catchment areas. METHODS We therefore conducted a retrospective single-center review of all AML patients assessed at a large specialized cancer center in Ontario, Canada. RESULTS Between 2012 and 2017, 1,310 patients were assessed by our center for upfront AML therapy. The median distance was 33.1 km, with 29% of patients living more than 50 km away from the center. There was no significant difference in probability of intensive induction chemotherapy or clinical trial by distance from center, both in univariate and multivariable analysis adjusting for age, sex, cytogenetics and molecular testing, and performance status. There was no significant difference in overall survival by distance from center on univariate and multivariable analysis. CONCLUSION In conclusion, geographic distance from treatment center does not appear to impact choice of upfront therapy, participation in clinical trials, or clinical outcomes in this study of newly diagnosed patients with AML treated in a single-payer environment.

Abstract
INTRODUCTION The association between allergic rhinitis and otitis media with effusion (OME) has not yet been well studied in the Indian population. In our study, we have attempted to assess the role of nasal cytology on allergic rhinitis symptomatology and on middle ear dysfunction, and the diagnosis was established by symptomatology, AEC, and a nasal smear for eosinophils. MATERIAL AND METHODS The present study is a single-centre, hospital-based observational study and was conducted at the Department of Otorhinolaryngology and Head-Neck Surgery (All India Institute of Medical Sciences [AIIMS], Bhopal) among patients with symptoms of allergic rhinitis. The ENT examination included anterior rhinoscopy/diagnostic nasal endoscopy (zero-degree endoscope) along with otoscopy to examine the ear and nose. A nasal smear from the inferior turbinate of the nasal cavity was taken and then examined under a microscope to find out the percentage of eosinophils. The chi-squared test was used for group comparisons of categorical data. Statistical significance was kept at p < 0.05. RESULTS In this study, out of 126 subjects with allergic rhinitis, 62 (49.2%) had middle ear dysfunction. The most prevalent middle ear pathologies were eustachian tube dysfunction (ETD; 28 cases, 22%), chronic otitis media (COM [16.6%]), OME (5.5%), and acute otitis media (AOM [4.5%]). ETD made up 45.1% of the ear diseases, with COM (33.87%), OME (11.29%), and AOM (9.6%) following. The mean value of absolute eosinophil count (AEC) among the allergic rhinitis participants (n = 32) was found to be 392.42. Absolute eosinophilia was present in 10 patients out of the 32 subjects being tested. Middle ear pathology was found in 7 of the 10 subjects found positive for absolute eosinophilia. Among the ear pathologies found in the participants (n = 7), the most common were ETD and OME (n = 5). CONCLUSION There was no correlation between nasal smear cytology and the severity of nasal symptoms or middle ear disease. The majority of the participants were in nasal eosinophil grade I and showed sneezing as the most common nasal symptom and COM as the most common middle ear pathologic manifestation.

Gupta V, Begum Y, Singh A, Agrawal D. Perception of medical students towards teaching basic clinical skills in otorhinolaryngology through peer physical examination (PPE). JOURNAL OF EDUCATION AND HEALTH PROMOTION 2023; 12:172. [PMID: 37404916 PMCID: PMC10317272 DOI: 10.4103/jehp.jehp_1165_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Accepted: 11/10/2022] [Indexed: 07/06/2023]
Abstract
BACKGROUND Medical education is now largely learner centered with self-directed learning. The best method for teaching physical examination skills is difficult to determine. The process by which students examine each other as part of their learning process in anatomy and clinical skills is known as peer physical examination (PPE). The aim of this study was to demonstrate the perceptions of students toward PPE in ear, nose, throat, head, and neck. MATERIALS AND METHODS This cross-sectional study was conducted in 2018 among 100 medical students after obtaining ethical approval. In the PPE programme, students participated in a small group of 2-3 students. A self-administered questionnaire was also filled out by students before and after the program, which gathered demographic details and responses to the modified Peer Physical Examination Questionnaire (PPEQ). Significant associations (P < 0.05) were examined using ANOVA analysis. RESULTS In the present study, 81.5% of students have previously conducted examinations on fellow students. Prior to the program, the willingness to be examined (for throat) by a peer was 71.7%, which rose to 95.7% after the program. Most students replied that "I am concerned about being a possible object of sexual interest during PPE." A univariate analysis showed that age, gender, and residence of students were significantly associated with PPEQ scores (P < 0.05). CONCLUSION In the present study, it was observed that there was a change in the willingness for PPE before and after the programme and also that there was a change in the perception towards PPE following the program.

Abstract
BACKGROUND
Acute ischemic stroke secondary to large vessel occlusion is among the most serious complications associated with COVID‐19 infection resulting in worse morbidity and mortality. We sought to study the association between COVID‐19 infection and large vessel occlusion thrombus pathology to better define the etiopathogenesis of this atypical cause of stroke.
METHODS
Thrombi were collected during mechanical thrombectomy and stained using hematoxylin and eosin. Blinded analysis of pathology was prospectively performed by a board‐certified neuropathologist. Red blood cell, fibrin, and white blood cell predominance was ascertained. Concomitant peripheral blood counts and clinical and imaging data were collected and analyzed. All samples underwent performance of reverse transcription polymerase chain reaction for SARS‐CoV2.
RESULTS
Between January 2020 and February 2022, a total of 952 acute ischemic stroke admissions were seen at the University Medical Center of El Paso, TX. Of these, 195 patients (20.5%) had large vessel occlusions and underwent mechanical thrombectomy and 53 patients had thrombus collected and analyzed. Seven patients (3.6%) tested positive for SARS‐CoV2. COVID‐19 positive patients were more likely to be younger (mean 57.4 years;
P
=0.07), male (85.7%;
P
=0.03), and have red blood cell predominant thrombi (85.7%;
P
=0.03). There was a statistically significant association between peripheral neutrophil count and white blood cell lysis in the overall cohort (
P
=0.015), who did not differ according to COVID‐19 status.
CONCLUSION
Thrombi retrieved from patients who were COVID‐19 positive and had stroke demonstrated red blood cell predominance. This finding requires further investigation using appropriate immunohistochemical techniques in a larger cohort of patients.

Benefit of Early Ruxolitinib Initiation Regardless of Fibrosis Grade in Patients with Primary Myelofibrosis: A Post Hoc Analysis of the Single-Arm Phase 3b JUMP Study. Cancers (Basel) 2023; 15:2859. [PMID: 37345196 DOI: 10.3390/cancers15102859] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 04/28/2023] [Accepted: 05/11/2023] [Indexed: 06/23/2023] Open
Abstract
Bone marrow fibrosis (BMF) is an adverse prognostic factor for myelofibrosis (MF). The single-arm, open-label, phase 3b JUMP trial (NCT01493414) assessed the safety and efficacy of the JAK1/JAK2 inhibitor ruxolitinib in patients with symptomatic MF. This post hoc analysis investigated the impact of BMF grade on response and outcomes in patients with primary MF (PMF) from the JUMP study. BMF was assessed by biopsy and graded from 0 to 3; grades 0-1 were considered low-grade fibrosis (LGF) and grades 2-3 were considered high-grade fibrosis (HGF). Patients with LGF (n = 268) had lower rates of cytopenias at baseline but showed comparable disease burden vs. patients with HGF (n = 852). The proportion of patients achieving a spleen response was greater in the LGF group vs. the HGF group at Week 24 and at any time during the study, while overall survival estimates were improved in patients with LGF vs. patients with HGF. Early initiation of ruxolitinib therapy (within 2 years of diagnosis) was associated with increased response rates in all patients. These results highlight the efficacy of ruxolitinib in symptomatic patients with PMF, with the greatest clinical improvements observed in patients with LGF and in patients who received early treatment.

Abstract
BACKGROUND Surgical site infections after gastrointestinal perforation with peritonitis have significant morbidity, increased hospital stays, and cost of treatment. The appropriate management of these wounds is still debatable. METHODS Patients undergoing surgery for gastrointestinal perforation with peritonitis via midline incision were screened for inclusion. After the closure of the midline fascia, patients were randomized into an open negative pressure wound therapy group (application of negative pressure wound therapy and attempted delayed closure at day 4) or a standard care group (no negative pressure wound therapy and attempted delayed closure at day 4). Postoperative outcomes, including surgical site infection till 30 days, were compared between the groups. This was assessed by an independent assessor not involved in the study for delayed closure. Although a priori sample size was calculated, an interim analysis was performed due to slow recruitment during the COVID pandemic. After interim analysis, a continuation of the trial was deemed unethical and terminated. RESULTS Ninety-six patients were assessed, and 69 were randomized (34 in the negative pressure wound therapy group and 31 in the standard care group). The age, body mass index, comorbidities, blood loss, operative time, and stoma formation were comparable. The surgical site infection was significantly lower in the negative pressure wound therapy group compared to the standard care group (6 [18%] vs 19 [61%], P < .01). The number needed to prevent 1 surgical site infection was 2.3. In a subgroup analysis, the use of negative pressure wound therapy also significantly decreased the rate of surgical site infection in stoma patients (4 [30.7%] vs 9 [69.3%], P = .03). CONCLUSION Open negative pressure wound therapy significantly decreases the incisional surgical site infection rate in patients with a dirty wound secondary to gastrointestinal perforation with peritonitis.

Abstract
Climate change has resulted in extreme temperature and drought around the globe, which poses serious threat to food security. Both heat and drought stress affects the production and productivity of wheat crop. The present study was undertaken to evaluate 34 landraces and elite cultivars of Triticum spp. for phenological and yield-related traits under optimum, heat, and combined heat-drought stress environments during 2020-2021 and 2021-2022. The pooled analysis of variance showed significant genotype × environment interaction, suggesting an influence of stress on trait expression. The trait performance of genotypes exhibited significant reduction under combined heat-drought stress as compared to optimum and heat stress environments. The maximum seed yield penalty was observed under combined heat-drought stress environment as compared to heat stress alone. Regression analysis indicated significant contribution of number of grains per spike towards stress tolerance. Based on Stress Tolerance Index (STI), genotypes Local-17, PDW 274, HI-8802, and HI-8713 were identified to be tolerant to both heat and combined heat and drought stress at Banda, whereas genotypes DBW 187, HI-8777, Raj 4120, and PDW 274 were tolerant at Jhansi location. The genotype PDW 274 showed stress tolerance under all treatments at both the locations. The genotypes PDW 233 and PDW 291 showed highest stress susceptibility index (SSI) across the environments. The number of grains per spike and test kernel weight were positively associated with seed yield across the environments and locations. The selected genotypes Local-17, HI 8802, and PDW 274 were identified to be the potential sources of heat and combined heat-drought tolerance, which may be utilized in hybridization to develop tolerant wheat genotypes and also for mapping of underlying genes/quantitative trait loci (QTLs).

Abstract
BACKGROUND Improvements in survival after pancreaticoduodenectomy has increased the number of patients potentially at risk of pancreatic insufficiency. AIMS We studied long-term (> 1 year) pancreatic functions (endocrine and exocrine) after pancreaticoduodenectomy and aimed to recognize the impact of various clinicopathological factors and postoperative complications on pancreatic functions. METHODS All patients who underwent pancreaticoduodenectomy at least 1 year prior were recruited from July 2020 to December 2021. Endocrine function was assessed using HbA1c, fasting blood sugar and postprandial blood sugar levels. Pancreatic exocrine function was assessed clinically with history of steatorrhea and objectively with quantitative estimation of fecal elastase-1 levels in stool samples. Volume of remnant pancreas, parenchymal thickness and duct diameter were assessed by computed tomography. Quality of life assessment was done using SF-36 questionnaire. RESULTS Of the 106 patients assessed, 64 patients met the inclusion criteria. Endocrine insufficiency was noted in 51.6%, and 34.3% had new onset diabetes mellitus. The incidence of pancreatic exocrine insufficiency was 87.5% and severe insufficiency was found in 62.5% of patients. Twenty-nine (45.3%) patients had both exocrine and endocrine insufficiency. Patients with CRPOPF had higher risk of severe exocrine insufficiency (5 vs. 2, OR 1.57(0.28-8.81) p = 0.6). The SF-36 scores were lower than general population especially in role limitation due to physical health, role limitation due to emotional problems, energy/fatigue, general health perception and health change domains. CONCLUSION Post-pancreaticoduodenectomy patients have a high frequency of pancreatic insufficiency and should be screened for same. The post-operative pancreatic fistula increases the risk of pancreatic exocrine insufficiency.

Abstract
Background In India, facility-based surveillance for congenital rubella syndrome (CRS) was initiated in 2016 to estimate the burden and monitor the progress made in rubella control. We analyzed the surveillance data for 2016-2021 from 14 sentinel sites to describe the epidemiology of CRS. Method We analyzed the surveillance data to describe the distribution of suspected and laboratory confirmed CRS patients by time, place and person characteristics. We compared clinical signs of laboratory confirmed CRS and discarded case-patients to find independent predictors of CRS using logistic regression analysis and developed a risk prediction model. Results During 2016-21, surveillance sites enrolled 3940 suspected CRS case-patients (Age 3.5 months, SD: 3.5). About one-fifth (n = 813, 20.6%) were enrolled during newborn examination. Of the suspected CRS patients, 493 (12.5%) had laboratory evidence of rubella infection. The proportion of laboratory confirmed CRS cases declined from 26% in 2017 to 8.7% in 2021. Laboratory confirmed patients had higher odds of having hearing impairment (Odds ratio [OR] = 9.5, 95% confidence interval [CI]: 5.6-16.2), cataract (OR = 7.8, 95% CI: 5.4-11.2), pigmentary retinopathy (OR = 6.7, 95 CI: 3.3-13.6), structural heart defect with hearing impairment (OR = 3.8, 95% CI: 1.2-12.2) and glaucoma (OR = 3.1, 95% CI: 1.2-8.1). Nomogram, along with a web version, was developed. Conclusions Rubella continues to be a significant public health issue in India. The declining trend of test positivity among suspected CRS case-patients needs to be monitored through continued surveillance in these sentinel sites.

Abstract
BACKGROUND Myelofibrosis (MF)-associated constitutional symptoms can severely impact health-related quality of life. Clinical trials in MF traditionally measure symptom response to treatment as a landmark endpoint of total symptom score (TSS) reduction ≥50% from baseline. However, this dichotomous assessment provides a limited view of clinically relevant symptomatic changes. Herein we evaluated longitudinal change from baseline in TSS over the continuous 24-week period and individual symptom scores to obtain a more comprehensive understanding of symptom benefits experienced by patients with MF receiving therapy. METHODS Longitudinal symptom change was evaluated using mixed-effect model repeated measure (MMRM) methodology with individual item-level analyses to complement the interpretation of the landmark symptom results in the completed phase III SIMPLIFY studies of momelotinib in MF. MMRM compared mean change in TSS from baseline with Week 24 using data from all patient visits. Generalized estimating equations were used to estimate item-level odds ratios using multiple predictive imputations for missing data. RESULTS Momelotinib and ruxolitinib groups reported similar overall symptom improvements, with a TSS difference of <1.5 points between groups for each post-baseline visit in SIMPLIFY-1. In SIMPLIFY-2, the improvement in TSS observed in momelotinib-treated patients was consistent with that observed in SIMPLIFY-1, whereas progressive TSS deterioration was observed with control. Item-level scores were heterogeneous in both studies. A similar and greater proportion of momelotinib-treated patients were categorized as "improved" or "stable" compared with control in SIMPLIFY-1 and SIMPLIFY-2, respectively. Odds ratios for between-group comparison ranged from 0.75 to 1.21 in SIMPLIFY-1, demonstrating similarity in likelihood of symptom improvement. In SIMPLIFY-2, the likelihood of symptom improvement in each item was higher in the momelotinib arm. CONCLUSIONS These findings suggest that momelotinib provides clinically relevant symptom benefits in the JAK inhibitor-naïve and JAK inhibitor-exposed settings.

Abstract
Background Predicting response to biliary drainage is critical to stratify patients with acute cholangitis. Total leucocyte count (TLC) is one of the criteria for predicting the severity of cholangitis and is routinely performed. We aim to investigate the performance of neutrophil-lymphocyte ratio (NLR) in predicting clinical response to percutaneous transhepatic biliary drainage (PTBD) in acute cholangitis. Patients and methods This retrospective study comprised consecutive patients with acute cholangitis who underwent PTBD and had serial (baseline, day 1, and day 3) TLC and NLR measurements. Technical success, complications of PTBD, and clinical response to PTBD (based on multiple outcomes) were recorded. Univariate and multivariate analysis was performed to identify factors significantly associated with clinical response to PTBD. The sensitivity, specificity, and area under the curve of serial TLC and NLR for predicting clinical response to PTBD were calculated. Results Forty-five patients (mean age 51.5 years, range 22-84) met the inclusion criteria. PTBD was technically successful in all the patients. Eleven (24.4%) minor complications were recorded. Clinical response to PTBD was recorded in 22 (48.9%) patients. At univariate analysis, the clinical response to PTBD was significantly associated with baseline TLC (P = 0.035), baseline NLR (P = 0.028), and NLR at day 1 (P=0.011). There was no association with age, the presence of comorbidities, prior endoscopic retrograde cholangiopancreatography, admission to PTBD interval, diagnosis (benign vs. malignant), severity of cholangitis, organ failure at baseline, and blood culture positivity. At multivariate analysis, NLR-1 independently predicted the clinical response. Area under the curve of NLR at day 1 for predicting clinical response was 0.901. NLR-1 cut-off value of 3.95 was associated with sensitivity and specificity of 87% and 78%, respectively. Conclusion TLC and NLR are simple tests that can predict clinical response to PTBD in acute cholangitis. NLR-1 cut-off value of 3.95 can be used in clinical practice to predict response.

Abstract
BACKGROUND The tumor microenvironment plays a significant role in tumor growth, metastasis and chemoresistance via dysregulated signaling pathways. Toward this, an inflammatory chemokine, interleukin-8 (IL-8), is overexpressed in various cancers and is involved in tumor progression and chemoresistance. However, the mechanistic role of IL-8 in mediating metastasis and chemoresistance in oral squamous cell carcinoma (OSCC) is not known. METHODS AND RESULTS In the present study, we evaluated the effect of IL-8 in regulating metastasis as well as chemoresistance in OSCC cell lines. For this, IL-8 was blocked exogenously using neutralizing IL-8 monoclonal antibody and IL-8 levels were enhanced by exogenous supply of recombinant human IL-8 (rhIL-8) to OSCC cells. The epithelial-to-mesenchymal transition (EMT) was evaluated using qPCR, migration by scratch/wound healing assay and invasion ability using transwell assay. rIL-8 induced chemoresistance was studied by apoptosis assay and the nuclear localization of NFκB using immunocytochemistry. IL-8 was significantly overexpressed in OSCC patients and cell lines. While exogenous blockade of IL-8 significantly reduced EMT, migration and invasion potential in OSCC cells, IL-8 overexpression upregulated these cellular traits thereby confirming the role of IL-8 in OSCC metastasis. Exogenous blockade of IL-8 also reversed chemoresistance in cisplatin resistant OSCC subline via NFκB signaling. CONCLUSION IL-8 plays a crucial role in OSCC metastasis and its targeted blockade can help in management of cisplatin resistance.

Abstract
Introduction Fine needle aspiration cytology (FNAC) plays a vital role in the diagnosis of thyroid nodules. However, it is challenging due to the heterogeneity of thyroid nodules, overlapping cytomorphological features, and interobserver variability. Cytomorphometric analysis turns subjective observations into quantitative values. In this study, we performed cytomorphometric image analysis on cytological smears of thyroid nodules, classified according to The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). Materials and methods A retrospective analysis of Papanicolaou (PAP) and Hematoxylin & Eosin (H&E) stained fine needle aspirate smears from 50 patients with thyroid nodules with available follow-up histopathology was performed for a period of two years (March 2021 - March 2023), after obtaining approval from the institutional human ethical committee (IHEC-LOP/2020/IM0355). The nodules were categorized according to TBSRTC and were then subjected to cytomorphometric image analysis. Each nucleus was analyzed for 14 parameters, including aspect ratio, intensity, diameter, perimeter, roundness, area, fractal dimension, feret diameter, circularity, radii, fournier description, and chromatin texture parameters such as heterogeneity and clumpiness. The data obtained was analyzed through relevant statistical methods using SPSS version 23 (IBM Inc., Armonk, New York) and was compared by using the analysis of variance (ANOVA) test and post hoc test. Results Our results revealed that cytomorphometric image analysis not only distinguishes benign and malignant thyroid nodules but also can aid in categorizing thyroid nodules with predominant follicular patterns, such as follicular variant of papillary carcinoma, follicular adenoma and follicular carcinoma (p<0.001). Conclusions Morphometric analysis of cytological smears combined with cytomorphology has the potential to be an important tool in the diagnosis of thyroid nodules. It can improve diagnostic accuracy for better treatment and improved prognosis.

Abstract
There are variable presentations of complications of rhinosinusitis, which may be subtle especially due to use of antibiotics. Thus the classical picture as described by Chandler is rarely seen and threshold for diagnosing and treating a complication should be low. To identify possible risk factors for development of complications in acute bacterial rhinosinusitis (ABRS) and suggest a new method of reporting/classifying the complications. We conducted a retrospective study and observed the clinical presentation and risk factors of 9 patients who presented with complications of ABRS in our OPD during a period of 6 years, and then tried to formulate a reporting method based on the risk factors. We identified certain risk factors which include age, gender, sinus involved, extension beyond sinus, history of trauma, anatomical variations, and duration of symptoms. There are possible risk factors for development of complications. These factors can be studied in further details to ascertain their causal relationship in causing these complications. We also suggest a new method of reporting the complications. Such a reporting system would help in accurately identifying the exact severity of the disease, prognosticating the disease and guide treatment.

Abstract
Haploidentical donors offer a potentially readily available donor, especially for non-White patients, for blood or marrow transplantation (BMT). In this collaboration across North America, we retrospectively analyzed outcomes of first BMT using haploidentical donor and posttransplantation cyclophosphamide (PTCy) in MDS/MPN-overlap neoplasms (MDS/MPN), an otherwise incurable hematological neoplasm. We included 120 patients, 38% of non-White/Caucasian ethnicity, across 15 centers with median age at BMT 62.5 years. The median follow-up is 2.4 years. Graft failure was reported in 6% patients. At 3-years, nonrelapse mortality (NRM) was 25%, relapse 27%, grade 3-4 acute graft versus host disease (GVHD) 12%, chronic GVHD requiring systemic immunosuppression 14%, progression-free survival (PFS) 48% and overall survival (OS) 56%. On multivariable analysis, statistically significant associations included older age at BMT (per decade increment) with NRM (sdHR 3.28, 95%CI 1.30-8.25), PFS (HR 1.98, 95% 1.13-3.45) and OS (HR 2.01, 95% CI 1.11-3.63), presence of mutation in EZH2/RUNX1/SETBP1 with relapse (sdHR 2.61, 95%CI 1.06-6.44), and splenomegaly at BMT/prior splenectomy with OS (HR 2.20, 95%CI 1.04-4.65). Haploidentical donors are a viable option for BMT in MDS/MPN, especially for those disproportionately represented in the unrelated donor registry. Disease-related factors including splenomegaly and high-risk mutations dominate outcomes following BMT.

Abstract
Background
Antimicrobial resistance (AMR) poses a significant challenge for treating pneumococcal disease. This study assessed AMR trends in Streptococcus pneumoniae from US children.
Methods
We evaluated antibiotic resistance, defined as facility antimicrobial susceptibility reports of intermediate/resistant, in 30-day non-duplicate S. pneumoniae isolates from children (<18 years) with invasive (blood or cerebrospinal fluid/neurological) or non-invasive (respiratory or ear/nose/throat) isolates at 219 US hospital inpatient/outpatient settings in the BD Insights Research Database (January 2011-February 2020). We used descriptive statistics to characterize the percentage of AMR isolates and generalized estimated equations to assess variations in resistance over time.
Results
Of 7,605 S. pneumoniae isolates analyzed, 6,641 (87.3%) were from non-invasive sources. Resistance rates were higher in non-invasive versus invasive isolates. Isolates showed high observed rates of resistance to ≥1 drug class (56.8%), ≥2 drug classes (30.7%), macrolides (39.9%), and penicillin (39.6%) and significant annual increases in resistance to ≥1 drug class (+0.9%), ≥2 drug classes (+1.8%), and macrolides (+5.0%).
Conclusions
Among US children over the last decade, S. pneumoniae isolates showed persistently high rates of resistance to antibiotics and significant increases in ≥1 drug class, ≥2 drug classes, and macrolide resistance rates. Efforts to address AMR in S. pneumoniae may require vaccines targeting resistant serotypes and antimicrobial stewardship efforts.

Abstract
The results of conventional corrective procedures remain suboptimal for severe cubitus varus deformities (> 30°) in children. We present the results of shortening dome osteotomy for the correction of such deformities. PATIENTS AND METHODS We present retrospective review of prospectively collected data of 18 patients (11 boys and 7 girls) who underwent shortening dome osteotomy between January 2011 and December 2019 for severe cubitus varus deformities (> 30°) secondary to malunited supracondylar fracture. The procedure involved the removal of convexo-concave bone (5-8 mm wide) between the two domes. Humero-ulnar angles, lateral condylar prominence index (LCPI), and elbow range of movements were recorded preoperatively and postoperatively. RESULTS Mean age was 7.5 years (range 5 years-11 years). Indication for surgery was poor cosmesis in all the patients and tardy ulnar nerve symptoms in three patients. Mean preoperative humero-ulnar angle was 26.1° varus (range 22°-34°), while it was 7.1° valgus (range 0°-12°) for contralateral normal elbow. They were followed for a mean duration of 2.2 years (range 12 months-5.8 years). The mean postoperative valgus angle achieved was 7.3° (range 2°-12°) as total angular correction achieved was 34.4° (range 30°-44°) (p < 0.001). Radiological healing was observed in all the patients at mean duration of 7.1 weeks (range 5 weeks-9 weeks). Mean preoperative and postoperative LCPI were - 2.4 (range +4.7 to - 10.5) and - 1.7 (range +4.5 to - 5.1), respectively (p = 0.595). Three patients had pin tract infections and two of them responded to aseptic dressings and oral antibiotics, while another required early pin removal and additional protection in splint. All patients regained preoperative arc of motion within 6 months after the procedure. CONCLUSION Shortening dome osteotomy is a safe and effective method for correcting severe cubitus varus deformities (> 30°) secondary to malunited supracondylar fracture in children.

Abstract
The 3D edge-enhancing gradient-echo (EDGE) MR imaging sequence offers superior contrast-to-noise ratio in the detection of focal cortical dysplasia. EDGE could benefit from 7T MR imaging but also faces challenges such as image inhomogeneity and low acquisition efficiency. We propose an EDGE-MP2RAGE sequence that can provide both EDGE and T1-weighted contrast, simultaneously, improving data-acquisition efficiency. We demonstrate that with sequence optimization, EDGE images with sufficient uniformity and T1-weighted images with high gray-to-white matter contrast can be achieved.
