Background: Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and internal organs. Gastrointestinal tract (GIT) involvement may lead to malnutrition, which can in turn negatively affect morbidity, mortality, and quality of life. The aim of the study was to assess the prevalence of malnutrition in SSc patients with both the European Society of Clinical Nutrition and Metabolism (ESPEN) and the Global Leadership Initiative on Malnutrition (GLIM) criteria and to assess whether it relates with disease activity and severity.
Methods: Adult SSc patients were included in the study. Biochemical analyses, disease activity index (DAI), disease severity scale (DSS), anthropometric data, and body composition parameters for GLIM and ESPEN assessment were recorded at enrollment.
Results: One hundred and two SSc patients were enrolled (86 females, mean age 55 ± 14 years). The prevalence of malnutrition was 8.8% (9 of 102), according to ESPEN, and 16.6% (17 of 102), according to GLIM criteria. GLIM severity grading of malnutrition was moderate in 12.7% (13 of 102) and severe in 3.9% (4 of 102) . In SSc patients with malnutrition according to GLIM criteria, DAI and DSS were significantly higher than in SSc patients without malnutrition (P < .0001), whereas no association was observed between malnutrition and DAI or DSS when using the ESPEN criteria.
Conclusion: Prevalence of malnutrition is higher with GLIM than with ESPEN criteria. Irrespective of the method used, prevalence of malnutrition in SSc is lower than one would expect in a chronic, autoimmune disease with GIT involvement.

Role of Exercise Stress Echocardiography in Systemic Sclerosis: Pathophysiological and Prognostic Significance of the Systemic Sclerosis with a Heart Failure and Preserved Ejection Fraction Phenotype.

Aims: Left ventricular (LV) diastolic dysfunction and heart failure with preserved ejection fraction (HFpEF) are common cardiac complications of patients with systemic sclerosis (SSc). Exercise stress echocardiography is often used in symptomatic patients with SSc to detect abnormal increases in pulmonary pressures during exercise, but the pathophysiologic and prognostic significance of exercise stress echocardiography to assess the presence of HFpEF in these patients is unclear.
Methods And Results: Patients with SSc (n=140) underwent ergometry exercise stress echocardiography with simultaneous expired gas analysis.

Viral variant and host vaccination status impact infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), yet how these factors shift cellular responses in the human nasal mucosa remains uncharacterized. We performed single-cell RNA sequencing (scRNA-seq) on nasopharyngeal swabs from vaccinated and unvaccinated adults with acute Delta and Omicron SARS-CoV-2 infections and integrated with data from acute infections with ancestral SARS-CoV-2. Patients with Delta and Omicron exhibited greater similarity in nasal cell composition driven by myeloid, T cell and SARS-CoV-2 cell subsets, which was distinct from that of ancestral cases.

The aims of this study were to investigate the prevalence of cryofibrinogenemia in a cohort of patients with systemic sclerosis (SSc) regardless of clinical manifestations, who were admitted to our hospital and determine the associations among CF positivity, disease features and ongoing therapies. This was a monocentric and retrospective study. The inclusion criteria were a diagnosis of SSc (according to the ACR/EULAR 2013 classification criteria), regular administration of i.

Objectives: Patients' outcomes and experiences can be affected by rheumatologist knowledge and awareness of systemic sclerosis (SSc). Our survey, directed at UK-based rheumatologists, aimed to expand our understanding of the above points along with their ability to keep up to date with guidelines defining best practice.
Methods: Rheumatologists were invited to participate in an online survey, with the results analysed and presented descriptively and graphically by SRUK.

Background: Unsafe surgical practices are a preventable cause of morbidity and mortality. The WHO published its surgical safety checklist (SSC) to help reduce surgical errors and complications and improve patient outcomes. This study aims to audit compliance with the WHO's SSC and explore attitudes toward its implementation in hospitals within a low- and middle-income country.
