J Prosthet Dent 2023:S0022-3913(23)00463-8. [PMID: 37633728 DOI: 10.1016/j.prosdent.2023.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 07/11/2023] [Accepted: 07/12/2023] [Indexed: 08/28/2023]
Abstract
STATEMENT OF PROBLEM Aggressive surgical debridement including maxillectomy in patients with coronavirus disease 2019 (COVID-19) associated mucormycosis of the maxilla alters facial appearance, function, and an individual's overall quality of life (QOL). These patients require rehabilitation of defects with obturators to help them recover from esthetic and functional disabilities and regain near-normal quality of life. Because COVID-19 associated with mucormycosis is a newer entity, less is known about the quality of life of these patients after rehabilitation with obturators. Hence, the effects of COVID-19 associated with mucormycosis, treatment, and rehabilitation need to be evaluated to assess QOL. PURPOSE The purpose of this clinical study was to assess the impact on QOL after rehabilitation with obturators for participants with COVID-19-associated mucormycosis who underwent maxillectomy. MATERIAL AND METHODS Oral health impact profile-14 (OHIP-14) and obturator functioning scale (OFS) questionnaires were administered to 26 participants with COVID-19-associated mucormycosis of the maxilla who underwent maxillectomy and required rehabilitation with obturators. Questionnaire responses were received on numerical Likert scales of 0 to 4 for OHIP-14 and 1 to 5 for OFS. The repeated measures analysis of variance (ANOVA) with pairwise post hoc Bonferroni tests were used to evaluate and compare mean scores of OHIP-14 and OFS at different preoperative and postoperative stages (α=.05). RESULTS A total of 26 participants who underwent maxillectomy were provided with obturators. A higher mean ±standard deviation OHIP score was observed before rehabilitation at T1 (51.0 ±9.6) followed by 1 week after fabrication of the surgical obturator at T2 (18.6 ±16.4), and 1 week after fabrication of the interim obturator at T3 (4.7 ±8.2). The lower mean scores ±standard deviation were seen 1 week after the fabrication of definitive obturators at T4 (2.9 ±7.2). Comparison of the scores at T1, T2, T3, and T4 found significant difference (P≤.001). Similarly, higher mean ±standard deviation OFS scores were seen 1 week after rehabilitation with surgical obturators at T2 (27.3 ±12.6) and at least 1 week after fabrication with definitive obturators at T4 (15.7 ±5.6). A comparison of the scores at T2, T3, and T4 found significant differences (P≤.001). CONCLUSIONS Considerable improvement was seen in QOL with the fabrication of surgical obturators in participants who had received maxillectomy/debridement for mucormycosis. This improvement had a linear relationship with the time elapsed and the consecutive fitting of the obturators with healing.

Abstract
To develop a prognostic model for patients undergoing allogeneic hematopoietic cell transplantation (allo-HCT) for myelofibrosis (MF), we examined the data of 623 patients undergoing allo-HCT between 2000 and 2016 in the United States (the Center for International Blood and Marrow Transplant Research [CIBMTR] cohort). A Cox multivariable model was used to identify factors prognostic of mortality. A weighted score using these factors was assigned to patients who received transplantation in Europe (the European Bone Marrow Transplant [EBMT] cohort; n = 623). Patient age >50 years (hazard ratio [HR], 1.39; 95% confidence interval [CI], 0.98-1.96), and HLA-matched unrelated donor (HR, 1.29; 95% CI, 0.98-1.7) were associated with an increased hazard of death and were assigned 1 point. Hemoglobin levels <100 g/L at time of transplantation (HR, 1.63; 95% CI, 1.2-2.19) and a mismatched unrelated donor (HR, 1.78; 95% CI, 1.25-2.52) were assigned 2 points. The 3-year overall survival (OS) in patients with a low (1-2 points), intermediate (3-4 points), and high score (5 points) were 69% (95% CI, 61-76), 51% (95% CI, 46-56.4), and 34% (95% CI, 21-49), respectively (P < .001). Increasing score was predictive of increased transplant-related mortality (TRM; P = .0017) but not of relapse (P = .12). The derived score was predictive of OS (P < .001) and TRM (P = .002) but not of relapse (P = .17) in the EBMT cohort as well. The proposed system was prognostic of survival in 2 large cohorts, CIBMTR and EBMT, and can easily be applied by clinicians consulting patients with MF about the transplantation outcomes.

Abstract
BACKGROUND AND AIMS Gastric outlet and biliary obstruction are common manifestations of GI malignancies and some benign diseases for which standard treatment would be surgical gastroenterostomy and hepaticojejunostomy (ie, "double bypass"). Therapeutic EUS has allowed for the creation of an EUS-guided double bypass. However, same-session double EUS-guided bypass has only been described in small proof-of-concept series and lacks a comparison with surgical double bypass. METHODS A retrospective multicenter analysis was performed of all consecutive same-session double EUS-guided bypass procedures performed in 5 academic centers. Surgical comparators were extracted from these centers' databases from the same time interval. Efficacy, safety, hospital stay, nutrition and chemotherapy resumption, long-term patency, and survival were compared. RESULTS Of 154 identified patients, 53 (34.4%) received treatment with EUS and 101 (65.6%) with surgery. At baseline, patients undergoing EUS exhibited higher American Society of Anesthesiologists scores and a higher median Charlson Comorbidity Index (9.0 [interquartile range {IQR}, 7.0-10.0] vs 7.0 [IQR, 5.0-9.0], P < .001). Technical success (96.2% vs 100%, P = .117) and clinical success rates (90.6% vs 82.2%, P = .234) were similar when comparing EUS and surgery. Overall (11.3% vs 34.7%, P = .002) and severe adverse events (3.8% vs 19.8%, P = .007) occurred more frequently in the surgical group. In the EUS group, median time to oral intake (0 days [IQR, 0-1] vs 6 days [IQR, 3-7], P < .001) and hospital stay (4.0 days [IQR, 3-9] vs 13 days [IQR, 9-22], P < .001) were significantly shorter. CONCLUSIONS Despite being used in a patient population with more comorbidities, same-session double EUS-guided bypass achieved similar technical and clinical success and was associated with fewer overall and severe adverse events when compared with surgical gastroenterostomy and hepaticojejunostomy.

Abstract
Tuberculosis (TB) is a chronic granulomatous infectious disease with 25% morbidity due to extrapulmonary form. Hence, knowledge about varied presentations of extrapulmonary oropharyngeal type may help in early diagnosis and management in acute as well as chronic settings. This article describes immunocompetent patients' presentation with varied oropharyngeal manifestations and later diagnosed with tuberculous tonsillitis and tuberculous abscesses with Pott's spine. The varied manifestation of oropharyngeal TB, which is supposed to be a chronic condition, may help in early diagnosis in acute and chronic settings.

Momelotinib long-term safety and survival in myelofibrosis: integrated analysis of phase 3 randomized controlled trials. Blood Adv 2023; 7:3582-3591. [PMID: 37042865 PMCID: PMC10368854 DOI: 10.1182/bloodadvances.2022009311] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 02/08/2023] [Accepted: 03/06/2023] [Indexed: 04/13/2023] Open
Abstract
Momelotinib is the first inhibitor of Janus kinase 1 (JAK1) and JAK2 shown to also inhibit activin A receptor type 1 (ACVR1), a key regulator of iron homeostasis, and has demonstrated improvements in splenomegaly, constitutional symptoms, and anemia in myelofibrosis (MF). This long-term analysis pooled data from 3 randomized phase 3 studies of momelotinib (MOMENTUM, SIMPLIFY-1, and SIMPLIFY-2), representing MF disease from early (JAK inhibitor-naive) to late (JAK inhibitor-experienced) stages. Patients in the control arms (danazol in MOMENTUM, ruxolitinib in SIMPLIFY-1, and best available therapy in SIMPLIFY-2) could cross over to receive momelotinib at the end of the 24-week randomized period, and all patients could continue momelotinib treatment after the completion of these studies via an extended access protocol (XAP). Across these studies, 725 patients with MF received momelotinib; 12% remained on therapy for ≥5 years, with a median treatment exposure of 11.3 months (range, 0.1-90.4 months). The most common nonhematologic treatment-emergent adverse event (AE) occurring in ≥20% of patients was diarrhea (any grade, 27% and grade ≥3, 3%). Any-grade thrombocytopenia, anemia, and neutropenia occurred in 25%, 23%, and 7% of patients, respectively. The most common reason for momelotinib discontinuation was thrombocytopenia (4% discontinuation rate). The incidence of AEs of clinical importance (eg, infections, malignant transformation, peripheral neuropathy, and hemorrhage) did not increase over time. This analysis of one of the largest randomized trial databases for a JAK inhibitor to date in MF demonstrated a consistent safety profile of momelotinib without long-term or cumulative toxicity. These trials were registered at www.clinicaltrials.gov as: MOMENTUM (#NCT04173494), SIMPLIFY-1 (#NCT01969838), SIMPLIFY-2 (#NCT02101268), and XAP (#NCT03441113).

Abstract
BACKGROUND Antibiotic usage and antibiotic resistance (ABR) patterns changed during the COVID-19 pandemic. Inadequate empiric antibiotic therapy (IET) is a significant public health problem and contributes to ABR. We evaluated factors associated with IET before and during the COVID-19 pandemic to determine the impact of the pandemic on antibiotic management. METHODS This multicenter, retrospective cohort analysis included hospitalized US adults who had a positive bacterial culture (specified gram-positive or gram-negative bacteria) from July 2019 to October 2021 in the BD Insights Research Database. IET was defined as antibacterial therapy within 48 h that was not active against the bacteria. ABR results were based on susceptibility testing and reports from local facilities. Multivariate analysis was used to identify risk factors associated with IET in patients with any positive bacterial culture and ABR-positive cultures, including multidrug-resistant (MDR) bacteria. RESULTS Of 278,344 eligible patients in 269 hospitals, 56,733 (20.4%) received IET; rates were higher in patients with ABR-positive (n = 93,252) or MDR-positive (n = 39,000) cultures (34.9% and 45.0%, respectively). Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2)-positive patients had significantly higher rates of IET (25.9%) compared with SARS-CoV-2-negative (20.3%) or not tested (19.7%) patients overall and in the ABR and MDR subgroups. Patients with ABR- or MDR-positive cultures had more days of therapy and longer lengths of stay. In multivariate analyses, ABR, MDR, SARS-CoV-2-positive status, respiratory source, and prior admissions were identified as key IET risk factors. CONCLUSIONS IET remained a persistent problem during the COVID-19 pandemic and occurred at higher rates in patients with ABR/MDR bacteria or a co-SARS-CoV-2 infection.

Abstract
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), has re-emerged as one of the major concerns for global wheat production since the evolution of Ug99 and other virulent pathotypes of Pgt from East Africa, Europe, Central Asia, and other regions. Host resistance is the most effective, economic, and eco-friendly approach for managing stem rust. Understanding the virulence nature, genetic diversity, origin, distribution, and evolutionary pattern of Pgt pathotypes over time and space is a prerequisite for effectively managing newly emerging Pgt isolates through host resistance. In the present study, we monitored the occurrence of stem rust of wheat in India and neighboring countries from 2016 to 2022, collected 620 single-pustule isolates of Pgt from six states of India and Nepal, analyzed them on Indian stem rust differentials, and determined their virulence phenotypes and molecular genotypes. The Ug99 type of pathotypes did not occur in India. Pathotypes 11 and 40A were most predominant during these years. Virulence phenotyping of these isolates identified 14 Pgt pathotypes, which were genotyped using 37 Puccinia spp.-specific polymorphic microsatellites, followed by additional phylogenetic analyses using DARwin. These analyses identified three major molecular groups, demonstrating fewer lineages, clonality, and long-distance migration of Pgt isolates in India. Fourteen of the 40 recently released Indian wheat varieties exhibited complete resistance to all 23 Pgt pathotypes at the seedling stage. Twelve Sr genes were postulated in 39 varieties based on their seedling response to Pgt pathotypes. The values of slow rusting parameters i.e. coefficient of infection, area under disease progress curve, and infection rates, assessed at adult plant stage at five geographically different locations during two crop seasons, indicated the slow rusting behavior of several varieties. Six Sr genes (Sr2, Sr57, Sr58, Sr24, Sr31, and Sr38) were identified in 24 wheat varieties using molecular markers closely linked to these genes. These findings will guide future breeding programs toward more effective management of wheat stem rust.

Abstract
PURPOSE It is recommended to drain the pancreatic fluid collections later in the course of the acute necrotizing pancreatitis (ANP). However, earlier drainage may be indicated. We compared early (≤ 2 weeks) vs. late (3rd to 4th week) percutaneous catheter drainage (PCD) of acute necrotic collections (ANC). MATERIALS AND METHODS This retrospective study comprised ANP patients who underwent PCD of ANC. The diagnosis of ANP was based on revised Atlanta classification criteria and computed tomography performed between 5 and 7 days of illness. Patients were divided into two groups [1st 2 weeks (group I) and 3rd-4th weeks (group II)] based on the interval between the onset of pain and insertion of catheter. The technical success, clinical success, complications, and clinical outcomes were compared between the two groups. RESULTS One hundred forty-eight patients (74 in each group) were evaluated. The procedures were technically successful in all patients. The clinical success rate was 67.6% in group I vs. 77% in group II (p = 0.069). The incidence of complications was significantly higher in group I (n = 12, 16%) than group II (n = 4, 5.4%) (p = 0.034). These included 15 minor (11 in group I and 4 in group II) and one major complication (group I). Of the clinical outcomes, the need for surgery was significantly higher in group I than in group II (13 patients vs. 5 patients, p = 0.031). CONCLUSION Early PCD is as technically successful as late PCD in the management of ANC. However, early PCD is associated with higher surgical rate and higher incidence of complications.

Abstract
Allogeneic hematopoietic cell transplantation (allo-HCT) remains the only curative treatment for myelofibrosis. However, the optimal conditioning regimen either with reduced-intensity conditioning (RIC) or myeloablative conditioning (MAC) is not well known. Using the Center for International Blood and Marrow Transplant Research database, we identified adults aged ≥18 years with myelofibrosis undergoing allo-HCT between 2008-2019 and analyzed the outcomes separately in the RIC and MAC cohorts based on the conditioning regimens used. Among 872 eligible patients, 493 underwent allo-HCT using RIC (fludarabine/ busulfan n=166, fludarabine/melphalan n=327) and 379 using MAC (fludarabine/busulfan n=247, busulfan/cyclophosphamide n=132). In multivariable analysis with RIC, fludarabine/melphalan was associated with inferior overall survival (hazard ratio [HR]=1.80; 95% confidenec interval [CI]: 1.15-2.81; P=0.009), higher early non-relapse mortality (HR=1.81; 95% CI: 1.12-2.91; P=0.01) and higher acute graft-versus-host disease (GvHD) (grade 2-4 HR=1.45; 95% CI: 1.03-2.03; P=0.03; grade 3-4 HR=2.21; 95%CI: 1.28-3.83; P=0.004) compared to fludarabine/busulfan. In the MAC setting, busulfan/cyclophosphamide was associated with a higher acute GvHD (grade 2-4 HR=2.33; 95% CI: 1.67-3.25; P<0.001; grade 3-4 HR=2.31; 95% CI: 1.52-3.52; P<0.001) and inferior GvHD-free relapse-free survival (GRFS) (HR=1.94; 95% CI: 1.49-2.53; P<0.001) as compared to fludarabine/busulfan. Hence, our study suggests that fludarabine/busulfan is associated with better outcomes in RIC (better overall survival, lower early non-relapse mortality, lower acute GvHD) and MAC (lower acute GvHD and better GRFS) in myelofibrosis.

Abstract
Oral squamous cell carcinoma (OSCC) is the most common type of cancer among men in the Indian subcontinent. Cytokines regulate inflammation and angiogenesis in a variety of cancers. Genetic variability in the cytokine genes can potentially influence the predisposition to oral carcinogenesis. The aim of the current study was to investigate the associations of SNPs in cytokine genes with the susceptibility of oral squamous cell carcinoma. In the present study, we have analyzed the allelic frequency of 32 single nucleotide polymorphisms (SNPs) using MassArray-based iPLEX assay in 16 cytokine genes in 166 OSCC patients and 151 healthy subjects from central India. Out of 32 SNPs analyzed, five SNPs were significantly associated with the risk of OSCC. AA and GG genotypes of IL-1β +3953 were associated with an increased and decreased risk of OSCC, respectively. In several genetic models, GG genotype and G allele in IL-12A 3'UTR G>A were found to be associated with an increased risk of OSCC. Similarly, the GG genotype of IL-12B +1188 T>G was associated with increased susceptibility to OSCC. We conclude that SNPs in the genes coding for IL-1β, IL-12A and IL-12B are associated with increased genetic susceptibility to OSCC in the central Indian population.

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.

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: 0] [Impact Index Per Article: 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.
