Power electronics (PE) and high-frequency switching circuits are key to superior performance of electric vehicles. It is vital to monitor the condition of the PE components in real-time for safety and reliability. In this article, we propose two anomaly detection methods based on a combination of data preprocessing to suppress noise and outliers, multivariate regression models to predict signals of interest under nominal operation, and sequential analysis of residuals. In particular, the methods utilize median filtering to extract on-state medians in each switching cycle in nonlinear autoregressive exogenous neural network models or filtered on-state data in partial least squares-based models to represent the nominal circuit behavior. Optimal and approximate dynamic programming-based feature selection methods are developed to select the most informative signals or their transformations. Predictions from the learned models are used to generate the residuals for anomaly detection by Page's cumulative sum test. The proposed models and anomaly detection methods are validated on three accelerated aging experimental datasets, comprised of 60 power mosfet devices with low-frequency and high-frequency switching under disparate operating conditions. Due to the simplicity and efficiency of the data-driven anomaly detection schemes, the proposed methods can potentially be embedded in real-time digital platforms.

BACKGROUND: Risdiplam is an oral small molecule approved for the treatment of patients with spinal muscular atrophy, with approval for use in patients with type 2 and type 3 spinal muscular atrophy granted on the basis of unpublished data. The drug modifies pre-mRNA splicing of the SMN2 gene to increase production of functional SMN. We aimed to investigate the safety and efficacy of risdiplam in patients with type 2 or non-ambulant type 3 spinal muscular atrophy. METHODS: In this phase 3, randomised, double-blind, placebo-controlled study, patients aged 2-25 years with confirmed 5q autosomal recessive type 2 or type 3 spinal muscular atrophy were recruited from 42 hospitals in 14 countries across Europe, North America, South America, and Asia. Participants were eligible if they were non-ambulant, could sit independently, and had a score of at least 2 in entry item A of the Revised Upper Limb Module. Patients were stratified by age and randomly assigned (2:1) to receive either daily oral risdiplam, at a dose of 5·00 mg (for individuals weighing =20 kg) or 0·25 mg/kg (for individuals weighing

- Abstract
Anthropogenic warming of the oceans and associated deoxygenation are altering marine ecosystems. Current knowledge suggests that these changes might be reversible in the centennial timescale in the ocean surface and irreversible at deeper depth if global warming were to decline. However, knowledge on the persistence of their combined effects on marine ecosystems remains limited. Here we explore to what extent global warming will drive alterations on marine habitats by following the evolution of a metabolic index that captures the ecophysiological response of marine organisms to both changes in temperature and oxygen, through an idealised ramp-up ramp-down atmospheric CO2 concentration experiment. Using a multi-model approach, we find that changes in ocean temperature and oxygen drives a centuries-long irreversible loss of ~4% in the habitable volume of the upper 1000 m of the world ocean. These results suggest the combined effect of warming and deoxygenation will diminish the capability of the ocean to hold life far after recovering from a temperature overshoot.

Item does not contain fulltext Duchenne muscular dystrophy (DMD) is caused by the lack of dystrophin, but many patients have rare revertant fibers that express dystrophin. The skeletal muscle pathology of DMD patients includes immune cell infiltration and inflammatory cascades. There are several strategies to restore dystrophin in skeletal muscles of patients, including exon skipping and gene therapy. There is some evidence that dystrophin restoration leads to a reduction in immune cells, but dystrophin epitopes expressed in revertant fibers or following genome editing, cell therapy, or microdystrophin delivery after adeno-associated viral gene therapy may elicit T cell production in patients. This may affect the efficacy of the therapeutic intervention, and potentially lead to serious adverse events. To confirm and extend previous studies, we performed annual enzyme- linked immunospot interferon-gamma assays on peripheral blood mononuclear cells from 77 pediatric boys with DMD recruited into a natural history study, 69 of whom (89.6%) were treated with corticosteroids. T cell responses to dystrophin were quantified using a total of 368 peptides spanning the entire dystrophin protein, organized into nine peptide pools. Peptide mapping pools were used to further localize the immune response in one positive patient. Six (7.8%) patients had a T cell-mediated immune response to dystrophin at at least one time point. All patients who had a positive result had been treated with corticosteroids, either prednisolone or prednisone. Our results show that ∼8% of DMD individuals in our cohort have a pre-existing T cell-mediated immune response to dystrophin, despite steroid treatment. Although these responses are relatively low level, this information should be considered a useful immunological baseline before undertaking clinical trials and future DMD studies. We further highlight the importance for a robust, reproducible standard operating procedure for collecting, storing, and shipping samples from multiple centers to minimize the number of inconclusive data.

O artigo que aqui se apresenta em forma de narrativa autobiográfica, compreende a temática da formação e trabalho docente como valorização da subjetividade singular e plural que contribui na investigação das mais variadas formas de expressão que a categoria docente vivenciou e vivencia num contexto de Pandemia, uma vez que tal processo permite investigar a própria subjetividade, mas também a ação profissional nas dimensões temporal e espacial que se reorganizam. Deste modo, narramos aqui nossa experiência em dupla docência, ao longo do 1º semestre de 2020, em um curso de Licenciatura em Ciências Humanas em uma Faculdade de Educação no âmbito do Programa de Residência Educacional na cidade de São Paulo a partir de uma reflexão: como nós, orientadoras de residência, (re)significamos nossa atuação frente ao processo de ensino e aprendizagem no contexto de ensino remoto? Tal processo resultou em uma autorreflexão sobre os desafios e potencialidade do uso de recursos tecnológicos e audiovisuais na realização da atividade docente.

The small sample sizes inherent in rare and pediatric disease settings offer significant challenges for clinical trial design. In such settings, Bayesian adaptive trial methods can often pay dividends, allowing the sensible incorporation of auxiliary data and other relevant information to bolster that collected by the trial itself. Previous work has also included the use of one-arm trials augmented by the participants’ own natural history data, from which the future course of the disease in the absence of intervention can be predicted. Patient response can then be defined by the degree to which post-intervention observations are inconsistent with the predicted “natural” trajectory. While such trials offer obvious advantages in efficiency and ethical hazard (since they expose no new patients to a placebo, anathema to patients or their parents and caregivers), they can offer no protection against bias arising from the presence of any “placebo effect,” the tendency of patients to improve merely by being in the trial. In this paper, we investigate the impact of both static and transient placebo effects on one-arm responder studies of this type, as well as two-arm versions that incorporate a small concurrent placebo group but still borrow strength from the natural history data. We also propose more traditional Bayesian changepoint models that specify a parametric functional form for the patient’s post-intervention trajectory, which in turn allow quantification of the treatment benefit in terms of the model parameters, rather than semi-parametrically in terms of a response relative to some “null” model. We compare the operating characteristics of our designs in the context of an ongoing investigation of centronuclear myopathies (CNMs), a group of congenital neuromuscular diseases whose most common and severe form is X-linked, affecting approximately 1 in 50,000 newborn boys. Our results indicate our two-arm responder and changepoint methods can offer protection against placebo effects, improving power while protecting the trial’s Type I error rate. However, further research into innovative trial designs as well as ongoing dialog with regulatory authorities remain critically important in rare disease research.

Summary Background Spinal muscular atrophy is a rare, autosomal recessive, neuromuscular disease caused by biallelic loss of the survival motor neuron 1 (SMN1) gene, resulting in motor neuron dysfunction. In this STR1VE-EU study, we aimed to evaluate the safety and efficacy of onasemnogene abeparvovec gene replacement therapy in infants with spinal muscular atrophy type 1, using broader eligibility criteria than those used in STR1VE-US. Methods STR1VE-EU was a multicentre, single-arm, single-dose, open-label phase 3 trial done at nine sites (hospitals and universities) in Italy (n=4), the UK (n=2), Belgium (n=2), and France (n=1). We enrolled patients younger than 6 months (180 days) with spinal muscular atrophy type 1 and the common biallelic pathogenic SMN1 exon 7–8 deletion or point mutations, and one or two copies of SMN2. Patients received a one-time intravenous infusion of onasemnogene abeparvovec (1·1 × 1014 vector genomes [vg]/kg). The outpatient follow-up consisted of assessments once per week starting at day 7 post-infusion for 4 weeks and then once per month until the end of the study (at age 18 months or early termination). The primary outcome was independent sitting for at least 10 s, as defined by the WHO Multicentre Growth Reference Study, at any visit up to the 18 months of age study visit, measured in the intention-to-treat population. Efficacy was compared with the Pediatric Neuromuscular Clinical Research (PNCR) natural history cohort. This trial is registered with ClinicalTrials.gov , NCT03461289 (completed). Findings From Aug 16, 2018, to Sept 11, 2020, 41 patients with spinal muscular atrophy were assessed for eligibility. The median age at onasemnogene abeparvovec dosing was 4·1 months (IQR 3·0–5·2). 32 (97%) of 33 patients completed the study and were included in the ITT population (one patient was excluded despite completing the study because of dosing at 181 days). 14 (44%, 97·5% CI 26–100) of 32 patients achieved the primary endpoint of functional independent sitting for at least 10 s at any visit up to the 18 months of age study visit (vs 0 of 23 untreated patients in the PNCR cohort; p Interpretation STR1VE-EU showed efficacy of onasemnogene abeparvovec in infants with symptomatic spinal muscular atrophy type 1. No new safety signals were identified, but further studies are needed to show long-term safety. The benefit–risk profile of onasemnogene abeparvovec seems favourable for this patient population, including those with severe disease at baseline. Funding Novartis Gene Therapies.

International audience; Rationale: The relationship between the initial treatment strategy and survival in pulmonary arterial hypertension (PAH) remains uncertain. Objectives: To evaluate the long-term survival of patients with PAH categorized according to the initial treatment strategy. Methods: A retrospective analysis of incident patients with idiopathic, heritable, or anorexigen-induced PAH enrolled in the French Pulmonary Hypertension Registry (January 2006 to December 2018) was conducted. Survival was assessed according to the initial strategy: monotherapy, dual therapy, or triple-combination therapy (two oral medications and a parenteral prostacyclin). Measurements and Main Results: Among 1,611 enrolled patients, 984 were initiated on monotherapy, 551 were initiated on dual therapy, and 76 were initiated on triple therapy. The triple-combination group was younger and had fewer comorbidities but had a higher mortality risk. The survival rate was higher with the use of triple therapy (91% at 5 yr) as compared with dual therapy or monotherapy (both 61% at 5 yr) (P < 0.001). Propensity score matching of age, sex, and pulmonary vascular resistance also showed significant differences between triple therapy and dual therapy (10-yr survival, 85% vs. 65%). In high-risk patients (n = 243), the survival rate was higher with triple therapy than with monotherapy or dual therapy, whereas there was no difference between monotherapy and double therapy. In intermediate-risk patients (n = 1,134), survival improved with an increasing number of therapies. In multivariable Cox regression, triple therapy was independently associated with a lower risk of death (hazard ratio, 0.29; 95% confidence interval, 0.11-0.80; P = 0.017). Among the 148 patients initiated on a parenteral prostacyclin, those on triple therapy had a higher survival rate than those on monotherapy or dual therapy. Conclusions: Initial triple-combination therapy that includes parenteral prostacyclin seems to be associated with a higher survival rate in PAH, particularly in the youngest high-risk patients.

Myotubular myopathy, also called X-linked centronuclear myopathy (XL-CNM), is a severe congenital disease targeted for therapeutic trials. To date, biomarkers to monitor disease progression and therapy efficacy are lacking. The Mtm1−/y mouse is a faithful model for XL-CNM, due to myotubularin 1 (MTM1) loss-of-function mutations. Using both an unbiased approach (RNA sequencing [RNA-seq]) and a directed approach (qRT-PCR and protein level), we identified decreased Mstn levels in Mtm1−/y muscle, leading to low levels of myostatin in muscle and plasma. Myostatin (Mstn or growth differentiation factor 8 [Gdf8]) is a protein released by myocytes and inhibiting muscle growth and differentiation. Decreasing Dnm2 by genetic cross with Dnm2+/− mice or by antisense oligonucleotides blocked or postponed disease progression and resulted in an increase in circulating myostatin. In addition, plasma myostatin levels inversely correlated with disease severity and with Dnm2 mRNA levels in muscles. Altered Mstn levels were associated with a generalized disruption of the myostatin pathway. Importantly, in two different forms of CNMs we identified reduced circulating myostatin levels in plasma from patients. This provides evidence of a blood-based biomarker that may be used to monitor disease state in XL-CNM mice and patients and supports monitoring circulating myostatin during clinical trials for myotubular myopathy., Graphical Abstract, X-linked centronuclear myopathy (XL-CNM) is a severe congenital disease targeted for therapeutic trials. The authors identified decreased plasma myostatin levels in XL-CNM patients and mice. Decreasing Dnm2 in mice blocked or postponed disease progression and resulted in an increase in circulating myostatin, supporting monitoring circulating myostatin in XL-CNM clinical trials.

PURPOSE: An initiative aimed to increase the rate of advance care planning (ACP) activities for outpatients with metastatic cancer, an essential step to achieving goal concordant care. METHODS: Patients with metastatic cancer were identified by International Classification of Diseases-10 coding and later by oncologists' electronic health record documentation of metastatic tumor status. ACP activities were defined as either an ACP note, Advance Directive, Physician Orders for Life-Sustaining Therapy (POLST), or a Palliative Medicine (PM) consultation within the prior year. From 2017 to 2020, the initiative screened more than 5,000 total unique cancer patients per year. PM consultants were embedded in tumor boards, oncology care team meetings, and shared oncology clinic space. Quarterly reports were sent to 60 oncologists at three cancer care sites with data of their percentage of ACP activities for patients with metastatic cancer compared with their peers. Oncologists' identities were initially blinded, but later unblinded. Oncologists also received a monthly list of patients with metastatic cancer without ACP activities. RESULTS: The rate of ACP activities for patients with metastatic cancer increased from a baseline of 37% in July 2017 to 57% by the end of 2020. PM consultations increased from 12% to 39% and ACP notes increased from 16% to 29% during the same interval. There was no change in Advance Directive (17%-20%) or POLST completion (7%-6%). CONCLUSION: ACP activities are an essential step to achieve goal concordant care, and this initiative successfully increased ACP activities for patients with metastatic cancer. However, given that the main source of increased ACP activities during this initiative was PM referrals, further progress will depend upon strengthening the oncology care teams' ACP skills and motivation for completion.

To evaluate sensitivity to change and discriminant validity of the 20-item Motor Function Measure (MFM-20) in 2-7-year-old patients with spinal muscular atrophy types 1 (SMA1) or 2 (SMA2) treated with nusinersen.Children aged 2 to 7 years old with SMA1 or SMA2 treated with nusinersen were assessed at least three times using the MFM-20 over an average follow-up time of 17 months. Evolution of 4-month-standardized MFM-20 scores was calculated for each MFM-20 domain (D1 standing and transfers, D2 axial and proximal, D3 distal) and for the total score (TS).Included in the study were 22 SMA1 subjects and 19 SMA2 subjects. Baseline MFM scores were significantly lower in patients with SMA1 than SMA2 (TS 29.5% vs. 48.3%, D1 4.5% vs. 10.6%, D2 43.6% vs. 72.6%, D3 51.2% vs. 75.0%). When considering the mean change during nusinersen treatment, standardized over a 4-month period, TS was improved for both SMA1 (+ 4.1%, SRM 1.5) and SMA2 (+ 2.8%, SRM 0.89) patients. For SMA1 patients, considerable changes were observed in D2 (+ 6.2%, SRM 0.89) and D3 (+ 6.0%, SRM 0.72), whereas the change in D1 was small (+ 0.5%, SRM 0.44). In SMA2 2 subjects, D3 was improved to a larger extent (+ 4.2%, SRM 0.53) than D1 (+ 1.8% SRM 0.63) or D2 (+ 3.2%, SRM 0.69).Our results validate use of MFM-20 to monitor function of young SMA1 and SMA2 subjects treated with nusinersen. Significant motor function improvements following treatment were observed in both SMA1 and SMA2 patients.

International audience; BACKGROUND: Pulmonary venoocclusive disease (PVOD) is an uncommon form of pulmonary hypertension (PH) predominantly characterized by pulmonary vein and capillary involvement. An association between chemotherapy, in particular mitomycin C (MMC), and PVOD has been reported.RESEARCH QUESTION: What are the characteristics of MMC-induced PVOD, and what is the prognosis for patients with MMC-induced PVOD?STUDY DESIGN AND METHODS: We report the clinical, functional, radiologic, and hemodynamic characteristics at diagnosis and outcomes of patients with PVOD from the French PH Registry after exposure to MMC. The results are expressed as the median (minimum-maximum).RESULTS: From June 2011 to December 2018, 17 incident cases of MMC-induced PVOD were identified. At diagnosis, these patients had severe clinical and functional impairment, with 12 patients having a New York Heart Association (NYHA) functional class of III or IV and a 6-min walk distance of 220 (0-465) m. Right heart catheterization confirmed severe precapillary PH with a mean pulmonary artery pressure of 38 (30-52) mm Hg, a cardiac index of 2.2 (1.5-4) L/(min x m(2)), and pulmonary vascular resistance of 8.3 (5.1-14.5) Wood units. The diffusing capacity of the lungs for carbon monoxide was markedly decreased at 31% (20%-51%) of the theoretical values associated with severe hypoxemia. MMC was withdrawn for all patients, and 14 patients received specific pulmonary arterial hypertension (PAH) therapies. Among these patients, mild but statistically insignificant improvements were observed in NYHA functional class (P = .10), 6-min walk distance (P = .09), and pulmonary vascular resistance (-4.7 Wood units; P = .052) at reassessment (median delay of 4.8 months). Three patients experienced pulmonary edema requiring the cessation or reduction of PAH treatment. The median overall survival was 20 months, and the 6-, 12-, and 24-month survival rates were 76%, 58%, and 18%, respectively.INTERPRETATION: PVOD after MMC treatment is a rare but life-threatening complication associated with a poor prognosis despite MMC withdrawal and PAH-specific therapy.

Por meio de subsidios empiricos e teoricos e amparando-se no metodo materialista historico e dialetico, a investigacao demonstra que (i) a extincao da contribuicao sindical acarretou a reducao das negociacoes coletivas, bem como ensejou retracao qualitativa desde a referencia da classe trabalhadora; (ii) que as negociacoes coletivas concentraram-se em categoriais com maior tradicao e articulacao sindical; (iii) que a fragilizacao das entidades sindicais e a consequente reducao da abrangencia das protecoes trabalhistas individuais nao proporcionou esperado aquecimento da economia capitalista no pais em periodo de crise, fato que demonstra o papel funcional a reproducao da relacao social do capital cumprido pelo direito do trabalho. Palavras-chave: Crise capitalista; Negociacao coletiva; Contribuicao sindical. Abstract The paper discusses how the Act n. 13.467/2017 impacted collective bargaining in Brazil. Through empirical and theoretical subsidies and based on the historical and dialectical materialist method, the investigation shows that (i) the extinction of the union contribution resulted in reduction and qualitative retraction – from the reference of the working class – of collective bargaining; (ii) that collective bargaining was concentrated in categories with greater tradition and union articulation; (iii) that the weakening of unions and the consequent reduction in the scope of individual labor protections did not provide the expected heating up of the capitalist economy in the country in times of crisis, a fact that demonstrates the functional role fulfilled by labor law for the reproduction of the social relationship of capital. Keywords: Capitalist crisis; Collective bargaining; Union contribution.

The median (min-max) age at diagnosis was 17 years (2-53), with a female-to-male ratio of 1.5. At diagnosis, most of the patients (74%) were in functional class III or IV with severe hemodynamic compromise, including a median pulmonary vascular resistance (PVR) of 14.0 (4.2-31.5) Wood units (WU). An associated congenital heart disease (CHD) was found in 7 PAH patients (35%). Patients with CHD-associated PAH were significantly younger at diagnosis than PAH patients without CHD. Four patients (20%) suffered from recurrent haemoptysis requiring repeated arterial embolisations. Thirteen out of 16 patients (81%) of whom imaging was available displayed chest computed tomography abnormalities, including dilated, tortuous pulmonary vessels, ground-glass opacities as well as bronchial and non-bronchial arteries anomalies. After a median follow-up of 47 months (1-591 months), 10 patients underwent lung transplantation and one patient benefited from a heart-lung transplantation due to associated CHD. Histopathologic analysis of lung explants showed a congested lung architecture with severe pulmonary arterial remodelling, subpleural vessel dilation and numerous haemorrhagic foci.PAH due to

To compare the societal financial costs and quality of life (QoL) of untreated patients with spinal muscular atrophy (SMA) and treated patients identified because they presented symptoms or were identified by early testing (sibling or newborn screening).Data from two different sources were used: data collected prospectively in untreated patients from 2016 to 2018 and data collected during a prospective follow-up study from 2018 to 2021. Patients or their caregiver completed a questionnaire that included questions on direct medical and non-medical costs, indirect non-medical costs, and health-related QoL.Data (median; range) were available for 149 patients (93 untreated - 10 years; 2 years-59 years), 42 patients (6 years 3 months; 9 months-58 years) treated after presenting with symptoms, and 14 patients (1 year 7 months; 5 months-2 years) treated after early diagnosis. Total costs were lower in untreated patients due to the high cost of drugs used in treated patients. Costs were lower for treated patients who were identified by early testing than for treated patients identified because they presented with symptoms. In all groups, patients with two SMN2 copies had higher costs than those with more copies.Early patient identification and treatment offer the opportunity to reduce the total societal costs of SMA where treatments are available for presymptomatic and postsymptomatic patients.Untreated patients with spinal muscular atrophy had lower total financial costs than treated patients. Total financial costs were lower for treated patients identified by early screening than for treated patients identified after symptom onset. Direct financial costs excluding treatment were much lower in treated patients identified by early screening. Hospitalization costs were much lower in patients identified by early screening.COSTO ECONÓMICO Y CALIDAD DE VIDA DE PACIENTES CON ATROFIA MUSCULAR ESPINAL IDENTIFICADOS POR SÍNTOMAS O CRIBADO NEONATAL: OBJETIVO: Comparar los costos financieros sociales y la calidad de vida (QoL) de pacientes no tratados con atrofia muscular espinal (AME) y pacientes tratados, identificados porque presentaron síntomas o fueron identificados mediante pruebas tempranas (cribado de hermanos o recién nacidos). MÉTODO: Se utilizaron datos de dos fuentes diferentes: datos recopilados prospectivamente en pacientes no tratados de 2016 a 2018 y datos recopilados durante un estudio de seguimiento prospectivo de 2018 a 2021. Los pacientes o sus cuidadores completaron un cuestionario que incluía preguntas sobre cuestiones médicas y no médicas directas. -costos médicos, costos indirectos no médicos y calidad de vida relacionada con la salud. RESULTADOS: Los datos (mediana; rango) estaban disponibles para 149 pacientes (93 sin tratamiento - 10 años; 2 años - 59 años), 42 pacientes (6 años 3 meses; 9 meses - 58 años) tratados después de presentar síntomas y 14 pacientes (1 año 7 meses; 5 meses-2 años) tratados tras un diagnóstico precoz. Los costos totales fueron menores en los pacientes no tratados debido al alto costo de los medicamentos utilizados en los pacientes tratados. Los costos fueron más bajos para los pacientes tratados que fueron identificados mediante pruebas tempranas que para los pacientes tratados identificados porque presentaban síntomas. En todos los grupos, los pacientes con dos copias de SMN2 tuvieron costos más altos que aquellos con más copias. INTERPRETACIÓN: La identificación y el tratamiento tempranos de los pacientes ofrecen la oportunidad de reducir los costos sociales totales de la AME, en lugares donde los tratamientos están disponibles para pacientes presintomáticos y postsintomáticos.

EXECUTIVE SUMMARY With increased therapeutic capabilities in healthcare today, many patients with multiple progressive comorbidities are living longer. They experience recurrent hospitalizations and often undergo procedures that are not aligned with their personal goals. That is why it is essential to discuss and document healthcare preferences prior to an acute event when significant interventions could occur, especially for patients with serious and progressive illness. Completion of an advance directive and a physician order for life-sustaining treatment (POLST) supports provision of goal-concordant care. Further, for patients who have do not attempt resuscitation (DNAR) orders or are diagnosed with advanced dementia, having a POLST is essential. This may be best accomplished with hospitalization discharge plans. Our 896-bed academic medical center, Cedars-Sinai Medical Center, launched a quality initiative in 2015 to complete POLSTs for patients being discharged with DNAR status or with dementia returning to a skilled nursing facility. As part of interdisciplinary progression of care rounds, emphasis was placed on those patients for whom POLST completion was indicated. Proactive, facilitated discussions with patients, family members, and attending physicians were initiated to support POLST completion. The completed forms were then uploaded to the electronic health record. Individual units and physicians received regular feedback on POLST completion rates, and the data were later shared at medical staff quality improvement meetings.During the initiative, POLST completion rates for DNAR patients discharged alive rose from 41% in fiscal year (FY) 2014 to 75% in FY 2019. Similar improvement was seen for patients with dementia discharged to skilled nursing facilities, regardless of code status (rising from 14% in FY 2014 to 54% in FY 2019). Subsequently, we have expanded our efforts to include early discussion and completion of these advanced care planning documents for patients recently diagnosed with high mortality cancers (ovarian, pancreatic, lung, glioblastoma), focusing on the completion of advanced care planning documentation and palliative care referrals.

Item does not contain fulltext Aim: To perform cross-sectional and longitudinal miRNA profiling in plasma from Duchenne muscular dystrophy (DMD) subjects and find non-invasive biomarkers in DMD. Subjects/materials & methods: Plasma was collected from 14 age and sex matched controls and 46 DMD subjects. Free-circulating and extracellular vesicle (EV)-derived miRNA expression was measured by RT-qPCR. Results: Free-circulating and EVs derived miR-29c-3p and miR-133a-3p are dysregulated in DMD subjects. Free-circulating and EV-derived miR-29c-3p are reduced in DMD subjects undergoing daily corticosteroid treatment. Free-circulating miR-1-3p and miR-122-5p are longitudinally upregulated in ambulant DMD subjects. Conclusion: We detected novel free-circulating and EV-derived dysregulated miRNAs in plasma from DMD subjects and characterized the longitudinal profile of free-circulating miRNA on plasma from DMD subjects.

Summary Background Systemic sclerosis-associated interstitial lung disease (ILD) carries a high mortality risk; expert guidance is required to aid early recognition and treatment. We aimed to develop the first expert consensus and define an algorithm for the identification and management of the condition through application of well established methods. Methods Evidence-based consensus statements for systemic sclerosis-associated ILD management were established for six domains (ie, risk factors, screening, diagnosis and severity assessment, treatment initiation and options, disease progression, and treatment escalation) using a modified Delphi process based on a systematic literature analysis. A panel of 27 Europe-based pulmonologists, rheumatologists, and internists with expertise in systemic sclerosis-associated ILD participated in three rounds of online surveys, a face-to-face discussion, and a WebEx meeting, followed by two supplemental Delphi rounds, to establish consensus and define a management algorithm. Consensus was considered achieved if at least 80% of panellists indicated agreement or disagreement. Findings Between July 1, 2018, and Aug 27, 2019, consensus agreement was reached for 52 primary statements and six supplemental statements across six domains of management, and an algorithm was defined for clinical practice use. The agreed statements most important for clinical use included: all patients with systemic sclerosis should be screened for systemic sclerosis-associated ILD using high-resolution CT; high-resolution CT is the primary tool for diagnosing ILD in systemic sclerosis; pulmonary function tests support screening and diagnosis; systemic sclerosis-associated ILD severity should be measured with more than one indicator; it is appropriate to treat all severe cases; no pharmacological treatment is an option for some patients; follow-up assessments enable identification of disease progression; progression pace, alongside disease severity, drives decisions to escalate treatment. Interpretation Through a robust modified Delphi process developed by a diverse panel of experts, the first evidence-based consensus statements were established on guidance for the identification and medical management of systemic sclerosis-associated ILD.

International audience; Introduction: The recent development of disease-modifying treatments in spinal muscular atrophy (SMA) type 1 shifted these patients' management from palliative to proactive. The aim of this study was to assess patients' nocturnal gas exchanges before noninvasive ventilation (NIV) initiation and their clinical evolution to determine if capnia is a good criterion to decide when to introduce respiratory support.Patients and methods: This multicentric retrospective study reports the respiratory management and evolution of 17 SMA type 1 children (10 females) for whom treatment with Nusinersen was initiated between 2016 and 2018.Results: Median [interquartile range-IQR] age at diagnosis and at first Nusinersen injection was of 4 [3;8] and 4 [3;9] months, respectively. Patients were followed during 38 [24;44] months. Thirteen (76%) patients were started on NIV at a median [IQR] age of 12 [9;18] months. Repeated hospitalizations and intensive care unit admissions were needed for 11 of them. Blood gas and nocturnal gas exchange recordings performed before NIV initiation were always normal. 9/13 X-ray performed before NIV showed atelectasis and/or acute lower respiratory tract infections. There was a significant decrease in the total number of hospital admissions between the first and second year of treatment (p = 0.04).Conclusion: This study shows that patients do not present with nocturnal hypoventilation before respiratory decompensations and NIV initiation, and suggests that a delay in NIV initiation might result in respiratory complications. There is a need for disease-centered guidelines for the respiratory management of these patients, including NIV indications.

RationaleThe characteristics of patients with respiratory complaints and/or lung radiologic abnormalities after hospitalisation for coronavirus disease 2019 (COVID-19) are unknown. The objectives were to determine their characteristics and the relationships between dyspnoea, radiologic abnormalities and functional impairment.MethodsIn the COMEBAC (Consultation Multi-Expertise de Bicêtre Après COVID-19) cohort study, 478 hospital survivors were evaluated by telephone 4 months after hospital discharge, and 177 who had been hospitalised in an intensive care unit (ICU) or presented relevant symptoms underwent an ambulatory evaluation. New-onset dyspnoea and cough were evaluated, and the results of pulmonary function tests and high-resolution computed tomography of the chest were collected.ResultsAmong the 478 patients, 78 (16.3%) reported new-onset dyspnoea, and 23 (4.8%) new-onset cough. The patients with new-onset dyspnoea were younger (56.1±12.3 versus 61.9±16.6 years), had more severe COVID-19 (ICU admission 56.4% versus 24.5%) and more frequent pulmonary embolism (18.0% versus 6.8%) (all p≤0.001) than patients without dyspnoea. Among the patients reassessed at the ambulatory care visit, the prevalence of fibrotic lung lesions was 19.3%, with extent versus 56±14 years, p=0.03), more frequently managed in an ICU (87.9 versus 47.4%, pversus 84.9±14.8% pred, pDLCO) (73.3±17.9 versus 89.7±22.8% pred, pDLCO ConclusionsNew-onset dyspnoea and mild fibrotic lesions were frequent at 4 months, but the association of new-onset dyspnoea, fibrotic lesions and low DLCO was rare.

Introduction The aim of this study was to study the feasibility of a fully integrated multiparametric imaging framework to characterize non-small cell lung cancer (NSCLC) at 3-T PET/MRI. Patients and methods An 18F-FDG PET/MRI multiparametric imaging framework was developed and prospectively applied to 11 biopsy-proven NSCLC patients. For each tumor, 12 parametric maps were generated, including PET full kinetic modeling, apparent diffusion coefficient, T1/T2 relaxation times, and DCE full kinetic modeling. Gaussian mixture model-based clustering was applied at the whole data set level to define supervoxels of similar multidimensional PET/MRI behaviors. Taking the multidimensional voxel behaviors as input and the supervoxel class as output, machine learning procedure was finally trained and validated voxelwise to reveal the dominant PET/MRI characteristics of these supervoxels at the whole data set and individual tumor levels. Results The Gaussian mixture model-based clustering clustering applied at the whole data set level (17,316 voxels) found 3 main multidimensional behaviors underpinned by the 12 PET/MRI quantitative parameters. Four dominant PET/MRI parameters of clinical relevance (PET: k2, k3 and DCE: ve, vp) predicted the overall supervoxel behavior with 97% of accuracy (SD, 0.7; 10-fold cross-validation). At the individual tumor level, these dimensionality-reduced supervoxel maps showed mean discrepancy of 16.7% compared with the original ones. Conclusions One-stop-shop PET/MRI multiparametric quantitative analysis of NSCLC is clinically feasible. Both PET and MRI parameters are useful to characterize the behavior of tumors at the supervoxel level. In the era of precision medicine, the full capabilities of PET/MRI would give further insight of the characterization of NSCLC behavior, opening new avenues toward image-based personalized medicine in this field.

Objectives To formulate new "Choosing Wisely" for Critical Care recommendations that identify best practices to avoid waste and promote value while providing critical care. Data sources Semistructured narrative literature review and quantitative survey assessments. Study selection English language publications that examined critical care practices in relation to reducing cost or waste. Data extraction Practices assessed to add no value to critical care were grouped by category. Taskforce assessment, modified Delphi consensus building, and quantitative survey analysis identified eight novel recommendations to avoid wasteful critical care practices. These were submitted to the Society of Critical Care Medicine membership for evaluation and ranking. Data synthesis Results from the quantitative Society of Critical Care Medicine membership survey identified the top scoring five of eight recommendations. These five highest ranked recommendations established Society of Critical Care Medicine's Next Five "Choosing" Wisely for Critical Care practices. Conclusions Five new recommendations to reduce waste and enhance value in the practice of critical care address invasive devices, proactive liberation from mechanical ventilation, antibiotic stewardship, early mobilization, and providing goal-concordant care. These recommendations supplement the initial critical care recommendations from the "Choosing Wisely" campaign.

Pulmonary and Respiratory Medicine - Abstract
BackgroundThe phenotype of pulmonary arterial hypertension (PAH) patients carryingSOX17pathogenic variants remains mostly unknown.MethodsWe report the genetic analysis findings, characteristics and outcomes of patients with heritable PAH carryingSOX17variants from the French Pulmonary Hypertension Network.Results20 patients and eight unaffected relatives were identified. The median (range) age at diagnosis was 17 (2–53) years, with a female:male ratio of 1.5. At diagnosis, most of the patients (74%) were in New York Heart Association Functional Class III or IV with severe haemodynamic compromise, including a median pulmonary vascular resistance of 14.0 (4.2–31.5) WU. An associated congenital heart disease (CHD) was found in seven PAH patients (35%). Patients with CHD-associated PAH were significantly younger at diagnosis than PAH patients without CHD. Four patients (20%) suffered from recurrent haemoptysis requiring repeated arterial embolisations. 13 out of 16 patients (81%) for whom imaging was available displayed chest computed tomography abnormalities, including dilated, tortuous pulmonary vessels, ground-glass opacities as well as anomalies of the bronchial and nonbronchial arteries. After a median (range) follow-up of 47 (1–591) months, 10 patients underwent lung transplantation and one patient benefited from a heart–lung transplantation due to associated CHD. Histopathological analysis of lung explants showed a congested lung architecture with severe pulmonary arterial remodelling, subpleural vessel dilation and numerous haemorrhagic foci.ConclusionsPAH due toSOX17pathogenic variants is a severe phenotype, frequently associated with CHD, haemoptysis and radiological abnormalities. Pathological assessment reveals severe pulmonary arterial remodelling and malformations affecting pulmonary vessels and thoracic systemic arteries.
