Discordance Between Patient and Physician Global Assessments in Early Systemic Sclerosis

open access: yesArthritis Care &Research, EarlyView.
Objective This study aims to identify factors associated with patient global assessment (PtGA) and physician global assessment (PhGA) and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (<5 years) from the Collaborative National Quality and Efficacy Registry were included.

New organic matter degradation proxies: Valid in lake systems? [PDF]

open access: yes, 2004
We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...

The Gut–Heart Axis in Systemic Sclerosis: Evidence From a Large Prospective Early Disease Cohort

open access: yesArthritis Care &Research, EarlyView.
Objective Cardiac involvement significantly impacts prognosis in systemic sclerosis (SSc), highlighting the need for early risk stratification. Gastrointestinal (GI) symptoms are common and often manifest early. Emerging data suggest a link between GI and cardiac manifestations, possibly through shared mechanisms like dysautonomia.

Carbon, light organic matter and oxidizable organic carbon fractions

open access: yesComunicata Scientiae, 2010
A avaliação da matéria orgânica leve em água e o fracionamento do carbono orgânico por diferentes graus de oxidação podem contribuir para o entendimento da dinâmica da matéria orgânica do solo em áreas sob manejo orgânico. Este trabalho teve como objetivo avaliar o carbono orgânico total (COT) do solo, a matéria orgânica leve (MOL) em água e frações ...
