Response to pharmacological and device-based therapy for heart failure (HF) may vary by sex. We examined sex differences in response to ambulatory hemodynamic monitoring in clinical practice using the CardioMEMS PAS (Post-Approval Study). The CardioMEMS PAS was a prospective, single-arm, multicenter, open-label study of 1200 adults with New York Heart Association class III HF and at least 1 HF hospitalization (HFH) within 12 months who underwent pulmonary artery pressure sensor implantation between 2014 and 2017. Changes in pulmonary artery pressure over time were stratified by ejection fraction <40% and sex. Clinical outcomes including HFH rate at 12 months, 1-year mortality, and quality of life were examined in women and men. Four hundred fifty-two women (38% of total) enrolled in the PAS were less likely to be White (78% versus 86%) and more likely to have nonischemic cardiomyopathy (44% versus 34%) and had significantly higher SBP (132 versus 124 mm Hg), mean ejection fraction (44% versus 36%), aEMS PAS had similar reductions from baseline in pulmonary artery pressure over 1 year and experienced similar reductions in HFH. Hemodynamic monitoring provides similar benefit with regard to HF events in both women and men. Registration URL https//www.clinicaltrials.gov; Unique identifier NCT02279888. Cardiomyopathy is a major clinical feature in Barth syndrome (BTHS), an X-linked mitochondrial lipid disorder caused by mutations in ( ), encoding a mitochondrial acyltransferase required for cardiolipin remodeling. Despite recent description of a mouse model of BTHS cardiomyopathy, an in-depth analysis of specific lipid abnormalities and mitochondrial form and function in an in vivo BTHS cardiomyopathy model is lacking. We performed in-depth assessment of cardiac function, cardiolipin species profiles, and mitochondrial structure and function in our newly generated cardiomyocyte-specific knockout mice and Cre-negative control mice (n≥3 per group). cardiomyocyte-specific knockout mice recapitulate typical features of BTHS and mitochondrial cardiomyopathy. Fewer than 5% of cardiomyocyte-specific knockout mice exhibited lethality before 2 months of age, with significantly enlarged hearts. More than 80% of cardiomyocyte-specific knockout displayed ventricular dilation at 16 weeks of age and surviveodel mirrors multiple physiological and biochemical aspects of BTHS cardiomyopathy. Our results give important insights into the underlying cause of BTHS cardiomyopathy and provide a framework for testing therapeutic approaches to BTHS cardiomyopathy, or other mitochondrial-related cardiomyopathies. Trimethylamine N-oxide (TMAO)-a gut-derived metabolite-is elevated in heart failure (HF) and linked to poor prognosis. We investigated variations in TMAO in HF, left ventricular assist device (LVAD), and heart transplant (HT) and assessed its relation with inflammation, endotoxemia, oxidative stress, and gut dysbiosis. We enrolled 341 patients. TMAO, CRP (C-reactive protein), IL (interleukin)-6, TNF-α (tumor necrosis factor alpha), ET-1 (endothelin-1), adiponectin, lipopolysaccharide, soluble CD14, and isoprostane were measured in 611 blood samples in HF (New York Heart Association class I-IV) and at multiple time points post-LVAD and post-HT. Gut microbiota were assessed via 16S rRNA sequencing among 327 stool samples. Multivariable regression models were used to assess the relationship between TMAO and (1) New York Heart Association class; (2) pre- versus post-LVAD or post-HT; (3) biomarkers of inflammation, endotoxemia, oxidative stress, and microbial diversity. ln-TMAO was lower among HF New York He levels were independent from measures of inflammation, endotoxemia, oxidative stress, and gut dysbiosis.The effective implementation of locally adapted cancer care solutions in low- and middle-income countries continues to be a challenge in the face of fragmented and inadequately resourced health systems. Consequently, the translation of global cancer care targets to local action for patients has been severely constrained. City Cancer Challenge (C/Can) is leveraging the unique value of cities as enablers in a health systems response to cancer that prioritizes the needs of end users (patients, their caregivers and families, and health care providers). C/Can's City Engagement Process is an implementation framework whereby local stakeholders lead a staged city-wide process over a 2- to 3-year period to assess, plan, and execute locally adapted cancer care solutions. CB1954 Herein, the development and implementation of the City Engagement Process Framework (CEPF) is presented, specifying the activities, outputs, processes, and indicators across the process life cycle. Lessons learned on the application of the framework in the first so-called Key Learning cities are shared, focusing on the early outputs from Cali, Colombia, the first city to join C/Can in 2017. Creating lasting change requires the creation of a high-trust environment to engage the right stakeholders as well as adapting to local context, leveraging local expertise, and fostering a sustainability mindset from the outset. In the short term, these early learnings inform the refinement of the approach in new cities. Over time, the implementation of this framework is expected to validate the proof-of-concept and contribute to a global evidence base for effective complex interventions to improve cancer care in low- and middle-income countries.Potato cyst nematodes (PCN), the umbrella term for Globodera rostochiensis and G. pallida, co-evolved with their Solanaceous hosts in the Andeans. From there, PCN proliferated worldwide to virtually all potato production areas. PCN is a major factor limiting the potato production in Indonesia. In our survey, only G. rostochiensis was found. Fourteen field populations were collected on Java and Sumatra, and unique variants were called by mapping re-sequencing data on a G. rostochiensis reference genome. A phylogenetic tree based on 1.4 million unique variants showed a genotypic separation between the outgroup, a Scottish Ro1 population, and all Indonesian populations. This separation was comparable in size to the genotypic distinction between the Javanese and the Sumatran PCN populations. Next, variants within PCN effector gene families SPRYSEC, 1106, 4D06, and venom allergen-like protein (VAL) that all interfere with the host innate immune system were compared. Distinct selective pressures acted on these effector families; while SPRYSECs (4,341 SNPs/indels) behaved like neutral genes, the phylogenetic trees of 1106, 4D06 and VAL proteins (respectively 235, 790 and 150 SNPs/indels) showed deviating topologies.
