Computer simulations have been completed that describe passage of a 10-km-diameter asteroid through the Earth's atmosphere and the subsequent cratering and ejecta dynamics caused by impact of the asteroid into both oceanic and continental sites. The asteroid was modeled as a spherical body moving vertically at 20 km/s with a kinetic energy of 2.6 × 1030 ergs (6.2 × 107 Mt ). Detailed material modeling of the asteroid, ocean, crustal units, sedimentary unit, and mantle included effects of strength and fracturing, generic asteroid and rock properties, porosity, saturation, lithostatic stresses, and geothermal contributions, each selected to simulate impact and geologic conditions that were as realistic as possible. Calculation of the passage of the asteroid through a U.S. Standard Atmosphere showed development of a strong bow shock wave followed by a highly shock compressed and heated air mass. Rapid expansion of this shocked air created a large low-density region that also expanded away from the impact area. Shock temperatures in air reached ∼20, 000K near the surface of the uplifting crater rim and were as high as ∼2000K at more than 30 km range and 10 km altitude. Calculations to 30 s showed that the shock fronts in the air and in most of the expanding shocked air mass preceded the formation of the crater, ejecta, and rim uplift and did not interact with them. As cratering developed, uplifted rim and target material were ejected into the very low density, shock-heated air immediately above the forming crater, and complex interactions could be expected. Calculations of the impact events showed equally dramatic effects on the oceanic and continental targets through an interval of 120 s. Despite geologic differences in the targets, both cratering events developed comparable dynamic flow fields and by ∼29s had formed similar-sized transient craters ∼39km deep and ∼62km across. Transient-rim uplift of ocean and crust reached a maximum altitude of nearly 40 km at ∼30s and began to decay at velocities of 500 m/s to develop large-tsunami conditions. After ∼30s, strong gravitational rebound drove both craters toward broad flat-floored shapes. At 120 s, transient crater diameters were ∼80km (continental) and ∼105km (oceanic) and transient depths were ∼27km; crater floors consisting of melted and fragmented hot rock were rebounding rapidly upward. By 60 s, the continental crater had ejected ∼2 × 1014t, about twice the mass ejected from the oceanic crater. By 120 s, ∼70, 000km3 (continental) and ∼90, 000km3 (oceanic) target material were excavated (no mantle) and massive ejecta blankets were formed around the craters. We estimate that in excess of ∼70% of the ejecta would finally lie within ∼3 crater diameters of the impact, and the remaining ejecta (∼1013t), including the vaporized asteroid, would be ejected into the atmosphere to altitudes as high as the ionosphere. Effects of secondary volcanism and return of the ocean over hot oceanic crater floor could also be expected to contribute substantial material to the atmosphere.

The case records of 499 victims of civil and terrorist violence were examined, and the presence or absence of post-traumatic stress disorder (PTSD) and associated features recorded. The results support the face, and predictive, validities of PTSD. ‘Acting as if the event were reoccurring’ and 'survivor guilt’ seemed not to be characteristic symptoms, and the homogeneity of the emotional state in PTSD was questionable. Only marital disharmony and suicidal behaviour were associated complications. PTSD seemed to be found in a wide range of stressors, but the danger in over-reliance on results from combat veterans is emphasised.

The problem of producing reliable thermocompression gold ball bonds to aluminum metallization has been discussed by many authors. In most of these discussions, little information is provided to relate bond reliability to process parameters-cleanliness and bonder settings. The influence of bond and capillary temperatures upon bond integrity is discussed. The use of beryllia capillaries to achieve the high capillary temperatures achievable with pulse tip bonding without sacrificing production throughput is discussed. An accelerated life test for ascertaining bond reliability is discussed and shown to be an effective tool for process prove-in. Finally, a bonding technique is discussed that not only meets the requirements of MIL STD 883A, but also will withstand temperature stresses equivalent to 300°C storage for 4 h, 2000 h of accelerated operating life, and 1300 temperature cycles.

Basic relationships that control the dynamic performance of toric variable-speed drives are studied. These basic toric relationships are then utilized to derive seven linear differential equations that describe a commercial model of a toric transmission. Experimental verification of these equations is made to support the theoretical work. By means of a numerical evaluation of the transfer functions, a simplified interpretation is made to show the relationships between transmission parameters and dynamic performance.

The sample studied was a group of 643 adults each seeking compensation for "Nervous Shock" and seen by a single Belfast psychiatrist for medico-legal assessment. Demographic information, risk factors, diagnosis, type of incident, symptoms and outcome were recorded for each patient. From the symptoms recorded, a subgroup of 23% were identified as suffering from Post-Traumatic Stress Disorder (PTSD) as defined in DSM III. This subgroup tended to be older, included more females, had more depressive symptoms and had more severe, prolonged disturbance. The findings document our experience of PTSD in the special context of Northern Ireland and suggest it may be a more useful term in describing psychological reaction to violence than the nebulous concept of "Nervous Shock" used at present by our courts.

In the years 1963--1977, the pathology department of the University of Colorado Medical School did 93 autopsies of patients with liver transplants. Fifteen of these patients had received a second graft. Sepsis was the greatest single cause of death or failure, and fungi and other organisms often considered opportunistic were frequent pathogens. Problems relating to removal of the liver from the donor, emplacement of the graft in the new host, and maintenance of the graft during the prolonged procedures together offer a monstrous challenge to the transplantation surgeon. All of these problems, classed as technical, include as complications infarction of the graft as the result of prolonged ischemia and blood loss or shock due to various causes, and all may produce alteration in structure of the liver; such changes may be misinterpreted as rejection. Rejection was a major cause of failure in only 5 patients, although the immunosuppression employed to control it contributed to the sepsis that so often was lethal. Hyperacute rejection was not observed in any of these transplanted livers, although 15 of these patients received a second transplant. Two of the patients whose grafts failed due to rejection had changes that indicated progression to an early stage of cirrhosis. We conclude that despite the persistent problems the liver is an organ peculiarly favorable for transplantation.

A case report with ultrastructural analysis of an apocrine carcinoma of the breast is presented. The key finding with electron microscopy is numerous large mitochondria with abundant incomplete cristae. The ultrastructure of this tumor is compared to the ultrastructure of apocrine cells in the skin, oncocytes, and apocrine metaplastic cells of the breast. The apocrine carcinoma cells have some of the features of typical metaplastic breast epithelium and some features of oncocytes. Their exact origin remains open to speculation.

The Nuu-Chah-Nulth are a tribe of 2,300 Pacific Northwest native Indians. A retrospective study has identified 157 requiring referral to rheumatologists over 15 years. Rheumatoid arthritis (RA) was found in 23, systemic lupus erythematosus (SLE) in 8, sacroiliitis 5, and Reiter's syndrome 1. Overlap syndromes with combinations of RA, SLE, scleroderma and polymyositis were seen in 9. Other rheumatic disorders included osteoarthritis 10, soft tissue rheumatism 14, and musculoskeletal complaints of known etiology (trauma, infection, neoplasm) 12. The remaining 75 patients suffered from periodic weather dependent joint swelling (52) or polyarthralgia (23) which were sometimes accompanied by features of systemic connective tissue disease. These findings are compared with rheumatic disease in other North American Indians.

This study is an attempt to evaluate the psychiatric sequelae in victims of violence in Northern Ireland between 1979 and 1984. Seven hundred and nineteen consecutive referrals for medico-legal reports were investigated using detailed analysis of case records. These clients were all seeking compensation for psychological injury allegedly sustained following a violent incident. Details of demographic data, diagnosis and utilization of treatment services were recorded. Clients showed a high rate of anxiety and depressive reactions and neuroses, with notable infrequency in the diagnosis of hysteria and phobic neurosis. A large number of people were prescribed drugs, a significant percentage continuing to take these for over one year. The significance of these results is discussed with regard to the issues of compensation neurosis and ‘nervous shock’.

A device was constructed to study dynamic penetration in crushed rock both in air and a high-vacuum (10^(-5) mm Hg) condition. The apparatus is designed to drop cylindrical, metal rods, pointed on one end, into cohesion-less crushed rock material. Dynamic penetration is studied as a function of several particle sizes and mixtures of these particle sizes. Other factors considered are the density of packing, probe dimensions, vacuum pressure, and vacuum degassing rates. Experimental results show that the density of packing of the crushed rock particles is the dominant factor affecting the dynan1ic penetration. The maximum penetration occurs in air in the crushed rock with low-density packing. The 1ninimum penetration occurs in air in densely packed material. Dynamic penetration in vacuum for the low-density and high-density packing lies between the results of penetration in air for the same packing conditions. At vacuum pressures above approximately 0.1 mm Hg, all penetration values approach the air penetration measurements.

Since cotton today is machine picked, the mere process of ginning creates a significant amount of trash and dust. A large cotton gin in Fresno operating at 23 bales per hour uses two rotating filters to control this material. Total emissions from the facility are in the order of 50 pounds per hour, or about one-half the emissions from a typical gin using cyclones as control equipment.

- Abstract
The problem investigated in this study was whether students who received computer-assisted reading instruction would display positive attitudes toward reading six or more months after the instruction was completed. A Likert attitude scale was administered to thirteen pre-adolescent and adolescent subjects to assess their attitudes toward reading six or more months after they had received computer-assisted instruction (CAI). In addition, a questionnaire was administered to the subjects' parents to determine their perception of the subjects' attitudes toward reading. Data obtained from the Likert scale indicated that the subjects' attitudes toward reading were neutral. An analysis of responses to the parent questionnaire revealed that the students' attitudes toward school-related reading were positive as a result of CAI. This study concluded that CAI had no apparent positive impact on the subjects' attitudes toward recreational reading.

McCarthy MJ, Wicker A, Roddy J, Remiker M, Roy I, McCoy M, Cerino ES, and Baldwin J
- Abstract
Despite the potential of mobile health (mHealth) to address high rates of depression and anxiety in underserved rural communities, most mHealth interventions do not explicitly consider the realities of rural life. The aim of this scoping review is to identify and examine the available literature on mHealth interventions that consider the needs of rural populations in order to gauge their feasibility and utility for addressing depression and anxiety. Additionally, we provide an overview of rural users' perceptions about and preferences for mHealth-delivered mental health screening and intervention systems. Out of 169 articles identified, 16 met inclusion criteria. Studies were conducted across a wide range of countries, age groups, and rural subpopulations including individuals with bipolar disorder, anxiety, perinatal depression, PTSD, and chronic pain, as well as refugees, veterans, and transgender and LGBTQ+ individuals. All interventions were in the feasibility/acceptability testing stage for rural users. Identified strengths included their simplicity, accessibility, convenience, availability of support between sessions with providers, and remote access to a care team. Weaknesses included problems with charging phone batteries and exceeding data limits, privacy concerns, and general lack of comfort with app-based support. Based upon this review, we provide recommendations for future mHealth intervention development including the value of developer-user coproduction methods, the need to consider user variation in access to and comfort with smartphones, and potential data or connectivity limitations, mental health stigma, and confidentiality concerns in rural communities., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

- Abstract
Introduction: Polymorphisms in genes responsible for the metabolism and transport of tacrolimus have been demonstrated to influence clinical outcomes for patients following allogeneic hematologic stem cell transplant (allo-HSCT). However, the clinical impact of germline polymorphisms specifically for oral formulations of tacrolimus is not fully described. Methods: To investigate the clinical impact of genetic polymorphisms in CYP3A4 , CYP3A5 , and ABCB1 on oral tacrolimus pharmacokinetics and clinical outcomes, we prospectively enrolled 103 adult patients receiving oral tacrolimus for the prevention of graft-versus-host disease (GVHD) following allo-HSCT. Patients were followed in the inpatient and outpatient phase of care for the first 100 days of tacrolimus therapy. Patients were genotyped for CYP3A5 *3 (rs776746), CYP3A4 *1B (rs2740574), ABCB1 exon 12 (rs1128503), ABCB1 exon 21 (rs2032582), ABCB1 exon 26 (rs1045642). Results: Expression of CYP3A5 *1 was highly correlated with tacrolimus pharmacokinetics in the inpatient phase of care ( p < 0.001) and throughout the entirety of the study period ( p < 0.001). Additionally, Expression of CYP3A5 *1 was associated with decreased risk of developing AKI as an inpatient ( p = 0.06). Variants in ABCB1 were not associated with tacrolimus pharmacokinetics in this study. We were unable to discern an independent effect of CYP3A4 *1B or *22 in this population. Conclusion: Expression of CYP3A5 *1 is highly influential on the pharmacokinetics and clinical outcomes for patients receiving oral tacrolimus as GVHD prophylaxis following allo-HSCT., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (Copyright © 2024 Seligson, Zhang, Zemanek, Johnson, VanGundy, Wang, Phelps, Roddy, Hofmeister, Li and Poi.)

- Abstract
Problem: Type 1 diabetes is associated with the risk of adverse outcomes for mother and baby., Background: How pregnant people adapt to the challenges of type 1 diabetes and engage with healthcare professionals can affect how likely they will be to maintain good glycaemic control. Therefore, it is important to understand the childbearing and care experiences of women with type 1 diabetes., Aim: To examine contemporary literature describing the childbearing experiences of women with type 1 diabetes over the last decade., Method: The review follows 5 stages of Arksey and O'Malley's scoping review framework. Four databases were searched for English language publications 2012-2023 using indexed terms and Boolean operators. 64 studies were retrieved, 10 included in the review. Braun and Clarke's thematic synthesis process was used to collate findings., Findings: Five key themes emerged: 1. Glycaemic control dominates the childbearing journey, 2. Emphasis on risk, 3. Importance of social and peer support, 4. Care organisation, systems, and communication, 5. The impact of technology on the childbearing experience., Conclusion: Based on lived experiences, women with type 1 diabetes value being treated as partners in their care by health professionals providing medical and midwifery services. Peer and social support from family, friends and the diabetes community can bring comfort and reassurance in a perceived 'medicalised' childbearing journey. Further research is needed on the impact of the use of type 1 diabetes technologies on childbearing experiences and how peer support can be incorporated into current care provision., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

- Abstract
Children with congenital heart disease (CHD) are at risk of malnutrition; however, there is limited information regarding the impact of nutritional status on organ dysfunction and outcomes after surgery for CHD. The study aim was to assess the association between malnutrition, organ dysfunction, and outcomes after surgery for CHD. Retrospective cohort study of patients aged 30 days to 18 years admitted to the cardiac intensive care unit (CICU) following cardiac surgery. Nutritional status (malnutrition defined as weight for age z-score < - 2) and validated organ dysfunction scores (pSOFA and PELOD-2) on CICU days 1 and 3 were collected. The cohort included 967 patients with a median age of 2.8 years (IQR 0.46, 7.12) and hospital survival of 98.86%. The prevalence of malnutrition was 18.5% (n = 179). By multivariable logistic regression analysis including age, malnutrition, cardiopulmonary bypass time, and duration of mechanical ventilation; High STAT category (OR 7.51 [1.03-54], p = 0.0462) and PSOFA score > 5 day 1 (OR 1.84 [1.25-2.72], p = 0.0021) were associated with mortality; in a similar model including the same variables; High STAT category (OR 9.12 [1.33-62], p = 0.0243) and PELOD-2 score > 5 day 1 (OR 1.75 [1.10-2.77], p = 0.0175) were associated with mortality. Malnutrition was associated with persistent or worsening organ dysfunction by pSOFA (p < 0.05) and PELOD-2 (p < 0.01) on day 3. Malnutrition was present in infants and children undergoing surgery for congenital heart disease. Organ dysfunction and high surgical risk were associated with mortality. Malnutrition was not associated with mortality but was associated with postoperative organ dysfunction., (© 2023.

- Abstract
Background: Despite experiencing many adversities, American Indian and Alaska Native populations have demonstrated tremendous resilience during the COVID-19 pandemic, drawing upon Indigenous determinants of health (IDOH) and Indigenous Nation Building., Objective: Our multidisciplinary team undertook this study to achieve two aims: (1) to determine the role of IDOH in tribal government policy and action that supports Indigenous mental health and well-being and, in turn, resilience during the COVID-19 crisis and (2) to document the impact of IDOH on Indigenous mental health, well-being, and resilience of 4 community groups, specifically first responders, educators, traditional knowledge holders and practitioners, and members of the substance use recovery community, working in or near 3 Native nations in Arizona., Methods: To guide this study, we developed a conceptual framework based on IDOH, Indigenous Nation Building, and concepts of Indigenous mental well-being and resilience. The research process was guided by the Collective benefit, Authority to control, Responsibility, Ethics (CARE) principles for Indigenous Data Governance to honor tribal and data sovereignty. Data were collected through a multimethods research design, including interviews, talking circles, asset mapping, and coding of executive orders. Special attention was placed on the assets and culturally, socially, and geographically distinct features of each Native nation and the communities within them. Our study was unique in that our research team consisted predominantly of Indigenous scholars and community researchers representing at least 8 tribal communities and nations in the United States. The members of the team, regardless of whether they identified themselves as Indigenous or non-Indigenous, have many collective years of experience working with Indigenous Peoples, which ensures that the approach is culturally respectful and appropriate., Results: The number of participants enrolled in this study was 105 adults, with 92 individuals interviewed and 13 individuals engaged in 4 talking circles. Because of time constraints, the team elected to host talking circles with only 1 nation, with participants ranging from 2 to 6 in each group. Currently, we are in the process of conducting a qualitative analysis of the transcribed narratives from interviews, talking circles, and executive orders. These processes and outcomes will be described in future studies., Conclusions: This community-engaged study lays the groundwork for future studies addressing Indigenous mental health, well-being, and resilience. Findings from this study will be shared through presentations and publications with larger Indigenous and non-Indigenous audiences, including local recovery groups, treatment centers, and individuals in recovery; K-12 and higher education educators and administrators; directors of first responder agencies; traditional medicine practitioners; and elected community leaders. The findings will also be used to produce well-being and resilience education materials, in-service training sessions, and future recommendations for stakeholder organizations., International Registered Report Identifier (irrid): DERR1-10.2196/44727., (©Julie A Baldwin, Angelica Alvarado, Karen Jarratt-Snider, Amanda Hunter, Chesleigh Keene, Angelina E Castagno, Alisse Ali-Joseph, Juliette Roddy, Manley A Begay Jr, Darold H Joseph, Carol Goldtooth, Carolyn Camplain, Melinda Smith, Kelly McCue, Andria B Begay, Nicolette I Teufel-Shone.

- Abstract
Background: Systemic sclerosis (SSc) associated interstitial lung disease (ILD) is a common complication of SSc, with a high mortality, despite current available treatments. Rituximab has shown some promising, although varied, results for the treatment of SSc-ILD., Aims: To determine whether rituximab stabilised or improved pulmonary function at 12 months, in patients with SSc-ILD., Methods: A retrospective analysis of patients with SSc-ILD who progressed despite conventional therapy and received rituximab between 2008 and 2019 was performed at two tertiary centres. Baseline percentage forced vital capacity (FVC) and percentage diffusing capacity of carbon monoxide (DLCO) were compared with 1-year post the first dose of rituximab. Mean and median change in FVC (%) and DLCO (%) were calculated. For those with available data, the FVC (%) and DLCO (%) 2 years and 1 year prior to rituximab were compared with the change 12-months post-rituximab., Results: Thirteen patients were included in the analysis. All patients demonstrated stability in their pulmonary function testing at 1-year post-rituximab. The mean FVC (%) was 57.18 (±16.93 standard deviation (SD)) prior to rituximab and 59.75 (±18.83 SD) 12-month post-rituximab, demonstrating an increase of 2.57 (±4.70 SD; P-value 0.07). The mean DLCO (%) increased from 37.10 (±18.41 SD) prior to rituximab to 38.03 (±19.83) post-rituximab. The mean change in DLCO (%) was 0.93 (±5.05 SD; P-value 0.53). In the 2 years preceding rituximab, the mean FVC (%) and DLCO (%) declined by 9.25 and 9.66 respectively., Conclusion: This case series suggests that rituximab might stabilise pulmonary function tests, and delay deterioration in patients with progressive SSc-ILD. These findings add to the growing body of evidence suggesting a role for rituximab in the treatment of SSc-ILD., (© 2022 Royal Australasian College of Physicians.)

- Abstract
Background: Venetoclax (VEN) in combination with hypomethylating agent (HMA) therapy is a standard treatment option for patients with newly diagnosed acute myeloid leukemia (AML); however, data are limited in the relapsed or refractory (R/R) populations and in those with poor-risk disease. A retrospective review was conducted involving patients with AML who received HMA alone or in combination with VEN (VEN + HMA)., Methods: VEN + HMA was compared to HMA alone in first-line and R/R settings. Patients were stratified by specific HMA and line of therapy. The primary endpoint was overall response rate (ORR) up to 6 months from start of treatment., Results: Fifty-two patients were evaluated for efficacy and 78 patients for safety. ORR was 67% (VEN + HMA) versus 80% (HMA) in the first line and 50% versus 22% in R/R setting. A greater clinical benefit was seen with VEN + HMA compared to HMA in both lines of therapy (first-line: 87% vs. 80%; R/R: 75% vs. 67%). The median duration of response was longer with VEN + HMA first-line, but shorter in the R/R setting compared to HMA (8.3 vs. 7.2 months and 2.5 vs. 3.7 months, respectively). Of the 32 patients who responded to therapy, 63% had a complex karyotype. Survival benefits were greater with VEN + HMA in both lines of therapy, although not statistically significant. Grade 3/4 neutropenia was reported in all patients receiving VEN, and 95% of these patients also experienced grade 3/4 thrombocytopenia. There were three cases of tumor lysis syndrome., Conclusion: The addition of VEN to HMA has consistently shown benefit as first-line treatment and may have some benefit in R/R settings as well. Further studies are needed to compare across various lines of treatment and unfavorable disease. Dynamic strategies that improve toxicity management should be considered., Competing Interests: Julianna Roddy, PharmD, BCOP, is currently employed with Merck Research Labs, Merck & Inc. Her contribution to this study was completed while she was employed at the James Cancer Hospital, Ohio State University. James Blachly, MD, has performed consulting and/or advisory board work for AbbVie, AstraZeneca, Astellas, KITE Pharma, and INNATE Pharma., (Copyright 2023, Freeman et al.)

- Abstract
Systemic sclerosis (SSc) is an autoinflammatory, fibrotic condition of unknown aetiology. The presence of detectable autoantibodies against diverse nuclear antigens, as well as strong HLA associations with disease, suggest autoimmune involvement, however the links between endogenous and exogenous risk factors and SSc pathology remain undetermined. We have conducted a genetic analysis of HLA inheritance in two independent and meta-analysed cohorts of 1,465 SSc cases and 13,273 controls, including stratified association analyses in clinical and autoantibody positive subgroups of disease. Additionally, we have used patient genotypes to impute gene dosages across the KIR locus, encoding paired activating and inhibitory lymphocyte receptors for Class I HLA ligands, to conduct the largest analysis of KIR-HLA epistatic interactions in SSc to date. We confirm previous Class II HLA associations with SSc risk and report a new Class I association with haplotype HLA-B*44:03-HLA-C*16:01 at genome-wide significance (GWS). We further report statistically significant HLA associations with clinical and serological subtypes of disease through direct case-case comparison, and report a new association of HLA-DRB1*15:01 , previously shown to bind topoisomerase-1 derived peptides, with anti-topoisomerase (ATA) positive disease. Finally, we identify genetic epistasis between KIRs and HLA class I ligands, suggesting genetic modulation of lymphocyte activation may further contribute to an individual's underlying disease risk. Taken together, these findings support future functional investigation into endogenous immunological and environmental stimuli for disrupted immune tolerance in SSc., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Hanson, Sahhar, Ngian, Roddy, Walker, Stevens, Nikpour, Assassi, Proudman, Mayes, Kenna and Brown.)

- Abstract
Myocarditis is a concerning potential consequence of COVID-19 infection, attributed to ventricular dysfunction, cardiac fibrosis, ventricular arrhythmias, cardiogenic shock, and sudden cardiac death. Recently, the Israeli Health Ministry announced that a small number of cases of myocarditis may be linked to second dose of Pfizer's BioNTech-partnered COVID-19 vaccine. The long-term impact of COVID-19 myocarditis and coronary microthrombosis which has also been described and the best therapies for these complications remain unknown. Indeed, monomorphic ventricular tachycardia and regular ventricular arrhythmias have previously been found to be more common in those recovered from myocarditis than in acute myocarditis itself. Follow-up assessment of cardiac function has been suggested for this cohort to detect and possibly prevent further cardiac events in the rehabilitation phase. Functional capacity has been shown to be a better determinant of long-term morbidity than diagnostic testing alone, but integrated approach is likely the way forward in clinical follow-up. Assessment of residual complications in the post-COVID-19 recovery phase may identify the population burden of long-term cardiac disease as a direct consequence of COVID-19., (© 2021.

- Abstract
Objective: We undertook this study to examine the X chromosome complement in participants with systemic sclerosis (SSc) as well as idiopathic inflammatory myopathies., Methods: The participants met classification criteria for the diseases. All participants underwent single-nucleotide polymorphism typing. We examined X and Y single-nucleotide polymorphism heterogeneity to determine the number of X chromosomes. For statistical comparisons, we used χ
2 analyses with calculation of 95% confidence intervals., Results: Three of seventy men with SSc had 47,XXY (P = 0.0001 compared with control men). Among the 435 women with SSc, none had 47,XXX. Among 709 men with polymyositis or dermatomyositis (PM/DM), seven had 47,XXY (P = 0.0016), whereas among the 1783 women with PM/DM, two had 47,XXX. Of 147 men with inclusion body myositis (IBM), six had 47,XXY, and 1 of the 114 women with IBM had 47,XXX. For each of these myositis disease groups, the excess 47,XXY and/or 47,XXX was significantly higher compared with in controls as well as the known birth rate of Klinefelter syndrome or 47,XXX., Conclusion: Klinefelter syndrome (47,XXY) is associated with SSc and idiopathic inflammatory myopathies, similar to other autoimmune diseases with type 1 interferon pathogenesis, namely, systemic lupus erythematosus and Sjögren syndrome., (© 2022 The Authors.

- Abstract
In patients hospitalized with COVID-19 pneumonia, both tocilizumab and baricitinib have been shown to have clinical benefit compared with placebo. To date, there are few data comparing the two treatments, and their relative benefits and harms are unknown. This study aims to evaluate the effectiveness of tocilizumab versus baricitinib in patients hospitalized with COVID-19 pneumonia and hypoxemia., Design: Retrospective cohort study., Setting: Seven inpatient acute-care hospitals in Wisconsin., Participants: Patients hospitalized with COVID-19, hypoxemia, and Pao
2 -to-Fio2 ratio less than or equal to 300 mm Hg, who received either tocilizumab or baricitinib., Interventions: Electronic chart review., Measurements and Main Results: Patients were divided into tocilizumab and baricitinib cohorts based on actual medication received. The primary outcome was hospital discharge alive and free from mechanical ventilation within 60 days, assessed by logistic regression. Three hundred eighty-two patients were included: 194 in the tocilizumab cohort and 188 in the baricitinib cohort. Most baseline characteristics in the two cohorts were similar. All patients received dexamethasone. Two patients were lost to follow-up. In the remaining 380 patients, probability of successful discharge in the two cohorts was quantitatively similar in unadjusted, multivariate-adjusted, and propensity score-matched analyses. Hospital length of stay, rates of thromboembolic events, and rates of hospital-acquired infections were all similar in the two cohorts., Conclusions: In patients hospitalized with COVID-19 pneumonia and hypoxemia who receive dexamethasone, treatment with tocilizumab or baricitinib appears to result in similar outcomes., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2022 The Authors.

- Abstract
Background: To describe the epidemiology, determinants and survival impact of gastric antral vascular ectasia (GAVE) in systemic sclerosis (SSc)., Methods: Consecutive SSc patients prospectively enrolled in the Australian Scleroderma Cohort Study (ASCS) were included. Univariable and multivariable logistic regression were used to determine the associations of GAVE with clinical manifestations and serological parameters. Kaplan-Meier (K-M) survival curves were used to estimate survival., Results: The prevalence of GAVE in this SSc cohort of 2039 SSc patients was 10.6% (n = 216) over a median follow-up period of 4.3(1.7-8.4) years. SSc patients with a history of GAVE compared with those without a history of GAVE were older at SSc onset [49.5 (40.0-58.2) vs 46.7 (36.0-56.7) years, p = 0.05]; more likely to have diffuse disease subtype (dcSSc) (35.3% vs 24.1%, p < 0.001); be negative for Scl-70, U1RNP and Scl/PM antibody (4.0% vs 16.1%, p < 0.001, 3.5% vs 7.4%, p = 0.041, 0.0% vs 2.0%, p = 0.042; and respectively) and positive for RNAP III antibody (24.9% vs 8.3%, p < 0.001). Those with GAVE had a worse HRQoL (p = 0.002). Independent determinants of GAVE included the presence of RNAP III antibody (OR 3.46, p < 0.001), absence of Scl-70 antibody (OR 0.23, p = 0.001), presence of GIT dysmotility (OR 1.64, p = 0.004), and digital ulcers; pits; or digital amputation (OR 1.59, p = 0.014)., Conclusions: GAVE is an underestimated and underappreciated SSc manifestation of SSc, which occurs with a relatively high frequency. Identifying an at-risk GAVE phenotype, as presented herein, is of practical importance as screening may prove advantageous given GAVE can be easily diagnosed and treated., (© 2022. The Author(s).)

- Abstract
Cytomegalovirus (CMV) is the most clinically significant infection after allogeneic hematopoietic-cell transplantation (allo-HCT) and is associated with increased mortality. The risk for CMV reactivation increases with graft versus host disease (GVHD). GVHD contributes to significant morbidity and mortality and is treated with immunosuppressive therapies that can further increase CMV infection risk. Prophylaxis with letermovir, an oral antiviral approved to prevent CMV, has been shown to decrease the incidence of CMV infection post-allo-HCT in patients at high risk of CMV reactivation, but there is a lack of data confirming this benefit in patients with GVHD. In this single-center, retrospective study, we assessed the incidence of clinically significant CMV infection (CS-CMVi) in allo-HCT patients who received letermovir prophylaxis ( n = 119) and who developed aGVHD compared to a control group ( n = 143) who did not receive letermovir. Among aGVHD patients, letermovir prophylaxis decreased CS-CMVi in patients with aGVHD (HR 0.08 [95% CI 0.03-0.27], p < 0.001), reduced non-relapsed mortality ( p = 0.04) and improved overall survival ( p = 0.04). This data suggests that letermovir prophylaxis improves outcomes by preventing CS-CMVi in patients with aGVHD.

- Abstract
Objective : We undertook a comprehensive cross-sectional analysis of a multicentred Australian cohort of systemic sclerosis (SSc) patients to evaluate the associations of anti-Ro52/TRIM21 with SSc pulmonary involvement. Method : The study included 596 patients from the Australian Scleroderma Cohort Study database whose anti-Ro52/TRIM21 status was known. Anti-Ro52/TRIM21 was measured via line immunoassay. Data on demographic variables, autoantibody profiles, presence of interstitial lung disease (ILD), presence of pulmonary arterial hypertension (PAH), oxygen saturation, Six-Minute Walk Test distance, Borg dyspnoea score, and lung function tests were extracted. SPSS software was used to examine associations using univariate and multivariate analyses. Results : Anti-Ro52/TRIM21 was present in 34.4% of SSc patients. In the cross-sectional analysis, anti-Ro52/TRIM21 was independently associated with PAH [odds ratio 1.75, 95% confidence interval (CI) 1.05-2.90], but not ILD or other surrogate measures of pulmonary involvement such as average patient oxygen saturation. The antibody, however, was also associated with a higher forced vital capacity/diffusing capacity of the lung for carbon monoxide ratio. Prospectively, anti-Ro52/TRIM21 was also associated with an increased risk of death in patients with SSc (hazard ratio 1.62, 95% CI 1.11-2.35), independent of confounding factors. The primary cause of death appeared to be related to PAH and/or ILD, and anti-Ro52/TRIM21 was associated with PAH-related complications. Conclusion : Anti-Ro52/TRIM21 was independently associated with PAH and mortality in SSc patients. Future longitudinal studies are recommended to investigate the timing and pathogenic mechanisms of this autoantibody in PAH.

- Abstract
Chimeric antigen receptor T cell (CAR T) therapy has been integrated into treatment algorithms for acute leukemia, lymphoma, and, most recently, multiple myeloma. The number of clinical trials in both hematologic and solid tumor malignancies for new products and potential indications continues to grow. The clinical toxicities of CAR T therapy include cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome, which often warrant inpatient admission for close monitoring and treatment. Consequently, many centers have built processes around the administration of these cells in the inpatient setting. As new products gain Food and Drug Administration approval with more manageable toxicity profiles, and as institutions gain experience with the management of these toxicities, outpatient administration and monitoring should be expected. In addition, payor reimbursements for inpatient treatment have put the sustainability of inpatient CAR T therapy in jeopardy, especially for centers with a payor mix that includes a high proportion of Medicare patients. This has the serious potential to limit access to care. As the use of CAR T therapy continues to expand, changes in payment models, care settings, or both are needed to ensure the sustainability of safe, efficient, and cost-effective treatment. This review outlines the efficacy and toxicity of currently approved products, as well as best practices to optimize the management of CAR T cell therapy in the outpatient setting., (Copyright © 2021 The American Society for Transplantation and Cellular Therapy.

- Abstract
Objective: To assess the outcome of empirical therapeutic interventions for synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome., Methods: The clinical features and treatment outcomes of a cohort of 21 patients diagnosed with SAPHO in Western Australia were reviewed retrospectively., Results: All 21 patients met published diagnostic criteria; 20 (95%) were Caucasian, and the median age was 47 years. The median follow-up was 6 years (range, 2 to 32 years). Three patients (14%) received no treatment; 18 (86%) required conventional synthetic disease-modifying antirheumatic drug (DMARDs). Thirteen (62%) had an initial good response to methotrexate; 8 relapsed and progressed to biologic DMARDs (bDMARDs) during a period of 14 years. Of the 13 recipients on a tumor necrosis factor inhibitor, 11 (85%) continued treatment for a median of 4 years (range, 1 to 14 years), whereas none of 3 recipients of interleukin 17/23 continued treatment (median, 4 months). Higher Physician Global Assessment scores (better outcomes) were observed in bDMARD recipients (mean, 7.06±2.24 [SD]) compared with non-bDMARD recipients (mean, 5.63±2.50; P =.1672) after a median of 3 years of therapy., Conclusion: This study describes the broad range of clinical manifestations in SAPHO, variable courses over time, and inconsistent outcomes with diverse empirical therapies. Moderately good long-term treatment outcomes were observed in most recipients of tumor necrosis factor inhibitor. Poorer outcomes were observed with bisphosphonates and interleukin 17/23 axis inhibitors; however, low numbers preclude robust comparison. Suboptimal treatment may be associated with poorer clinical outcomes and greater skeletal damage., Trial Registration: Australian and New Zealand Clinical Trials Registry: ACTRN12619000445178., (© 2021 The Authors.)

- Abstract
Objective: To describe the clinical characteristics and outcomes of systemic sclerosis-mixed connective tissue disease (SSc-MCTD) and SSc overlap syndrome., Methods: We included patients from the Australian Scleroderma Cohort Study who met American College of Rheumatology/European Alliance of Associations for Rheumatology criteria for SSc. Three mutually exclusive groups were created: SSc-MCTD, SSc overlap, and SSc only. Univariate comparison of clinical features was performed by analysis of variance or chi-square test. Survival analysis was performed using Kaplan-Meier (KM) curves and Cox proportional hazards regression models., Results: Of 1,728 patients, 97 (5.6%) had SSc-MCTD, and 126 (7.3%) had SSc overlap. Those with MCTD-SSc were more commonly Asian (18.3% versus 10.1% in SSc overlap, and 3.6% in SSc only; P < 0.0001) and younger at disease onset (38.4 years versus 46.5 or 46.8 years, P < 0.0001). Those with SSc-MCTD or SSc overlap were more likely to have limited cutaneous SSc. All 3 groups had similar frequency of interstitial lung disease (ILD), although pulmonary arterial hypertension (PAH) was less common in SSc overlap. Synovitis and myositis were more common in SSc overlap and SSc-MCTD than in SSc only. KM curves showed better survival in SSc-MCTD than SSc overlap or SSc only (P = 0.011), but this was not significant after adjustment for sex and age at disease onset. SSc-specific antibodies were survival prognostic markers, with antinuclear antibody centromere or anti-RNP conferring better survival than anti-Scl-70 or anti-RNA polymerase III (P = 0.005). Patients with SSc-MCTD and SSc overlap had lower mortality following diagnosis of ILD and PAH than patients with SSc only., Conclusion: This study provides insights into the clinical characteristics of patients with SSc-MCTD, SSc overlap, and SSc only and shows that anti-RNP antibodies are associated with better survival than anti-Scl-70 and anti-RNA polymerase III antibodies., (© 2020, American College of Rheumatology.)

- Abstract
Background: Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma. Recent advances in immunotherapy have resulted in the development of chimeric antigen receptor-modified T-cell (CAR-T) therapy, such as axicabtagene ciloleucel (axi-cel). However, axi-cel administration is not without risks of toxicity., Patients and Methods: This retrospective study of 37 patients with relapsed or refractory diffuse large B-cell lymphoma evaluated the incidence and severity of common and severe safety events after axi-cel treatment in a real-world setting. Ninety percent of patients had received 3 or more prior lines of therapy (median prior therapies 3, range 2-7) before receiving CAR-T therapy, and 32.4% had relapsed after prior stem-cell transplantation., Results: All but one patient experienced cytokine release syndrome (CRS) of any grade (97.3%). Of those 36 patients, 83.3% experienced maximum CRS grade of 1 or 2, occurring after a median of 27 hours and persisting for a median of 6 days. Twenty-seven patients (73.0%) experienced neurotoxicity of any grade. Of those 27 patients, 96.3% experienced maximum neurotoxicity grade of 2 or higher, occurring after a median of 145 hours (6 days) and persisting for a median of 7 days. All 10 patients aged 65 or older had neurotoxicity of grade 2 or higher, compared to 59.3% (11/27) under age 65 (P = .02). Patients with baseline Eastern Cooperative Oncology Group performance status score of 2 were significantly more likely to have shorter time to neurotoxicity compared to patients with performance status of 0 (P = .01)., Conclusion: With more real-life experience and data, we will be able to define and refine management of toxicities unique to CAR-T therapy., (Copyright © 2020 Elsevier Inc.
