Background: This study was aimed at evaluating the aerobic capacity of patients with antisynthetase syndrome (ASS) and dermatomyositis (DM) and analyzing possible relationships between aerobic capacity and disease status, cardiovascular diseases and their risk factors.

Methods: The study was a cross-sectional, single-center study that assessed the aerobic capacity of 22 women (13 with DM and 9 with ASS) who were matched by age and body mass index to 17 healthy women (control group). The aerobic capacity (oxygen uptake [VO peak], anaerobic threshold, respiratory compensation point and time-to-exhaustion) was evaluated using the cardiopulmonary treadmill test. Disease status was assessed using International Myositis Assessment & Clinical Studies Group (IMACS) set scores.

Results: The patients had low IMACS parameters that showed low or absent disease activity. The distribution of cardiovascular diseases and their risk factors was similar between the patients and the control group (P >  0.05) at the time of the analysis. The patients with DM and the control group had similar aerobic capacity. However, the patients with ASS exhibited significantly reduced aerobic capacity (relative VO peak, anaerobic threshold, respiratory compensation point and time to exhaustion) when compared to the control group. In addition, patients with ASS had a lower anaerobic threshold compared to the DM group. There were no significant relationships between the aerobic capacity and disease status, cardiovascular diseases and their risk factors.

Conclusion: In contrast to DM patients and healthy individuals, patients with stable ASS have significantly impaired aerobic capacity, which is unlikely to be totally explained by traditional cardiovascular diseases, their risk factors and disease status. Further studies are needed to corroborate our data and to clarify the cause of this reduced aerobic capacity in ASS.

Background/aim: Exertional breathlessness is a dominating symptom in cardiorespiratory disease, limiting exercise capacity. Multidimensional measurement has been proposed to capture breathlessness, but it is unknown whether it is useful to differentiate people with abnormal vs normal exertional breathlessness intensity.

Methods: This was a secondary analysis of a randomized controlled trial of outpatients aged ≥18 years performing a symptom-limited cycle incremental exercise test (IET).

Background: Aerobic exercises (AEs) have gained much interest in managing fibromyalgia (FM). This trial aimed to find out how AEs affect women with FM in terms of lung function, chest expansion, dyspnea, exercise capacity, and quality of life.

Methods: Eighty FM-diagnosed women were allocated randomly into 2 equal-sized groups.

Electronic address:

In this paper, zein-carboxymethyl starch (CMS) nanoparticles were prepared by antisolvent precipitation method to improve the stability of rutin (RT). The encapsulation efficiency, loading capacity, oxidation resistance, structural properties were evaluated. The results showed that electrostatic, hydrogen bond and hydrophobic interaction were the main driving forces for the formation of nanoparticles.
