ObjectiveWe aimed to determine the prevalence and clinical characteristics of self-reported hyperthyroidism in patients with sarcoidosis.MethodsA national registry-based study investigating 3836 respondents to the Sarcoidosis Advanced Registry for Cures questionnaire in the period between June 2014 and August 2019 was conducted. This registry is generated from a web-based questionnaire that is self-reported by patients with sarcoidosis. We compared patients with sarcoidosis who had hyperthyroidism with those who did not. We used multivariate logistic regression analysis to study the association between hyperthyroidism and different cardiac manifestations in patients with sarcoidosis.ResultsThree percent of the study respondents self-reported having hyperthyroidism and were generally middle-aged Caucasian women. Compared with patients without hyperthyroidism, patients with hyperthyroidism had more sarcoidosis-related comorbidities (59% vs 43%, P = .001) and more steroid-related comorbidities (56% vs 44%, P = .01), but there was no difference in the sarcoidosis-specific treatments they received, which included corticosteroids. Patients with hyperthyroidism reported sarcoidosis involvement of the heart (26.6% vs 14.9%, P = .005), kidneys (14.9% vs 8%, P = .033) and sinuses (17.7% vs 10.2%, P = .030) more frequently. Cardiac manifestations that were more frequently reported in patients with hyperthyroidism included atrial arrhythmias (11.3% vs 6.3%, P = .046), ventricular arrhythmias (17.2% vs 7.5%, P < .001), congestive heart failure (10.4% vs 5%, P = .017), and heart block (9.4% vs 4.7%, P = .036).ConclusionHyperthyroidism is infrequent in patients with sarcoidosis but is potentially associated with different cardiac manifestations. We suggest considering routine screening for hyperthyroidism in patients with sarcoidosis, especially in those with cardiac involvement. Further studies are needed to investigate the impact of identifying and treating hyperthyroidism in patients with sarcoidosis. 相似文献

Coal-smoke emissions of a thermal power plant affected the physio-chemical status of Peristrophe bicalyculata (Reth) Nees, as observed at the pre-flowering, flowering and post-flowering stages of plant growth. The nitrate level was
raised while nitrate reductase activity, and the soluble protein content of leaf declined heavily at the polluted site during
different stages of plant growth, compared to the control. The rate of photosynthesis also decreased under the pollution stress.
Sugar level in root, stem and leaves increased with growing age of the plant but was always lower at the polluted site than
at the reference site. In roots, the difference was marginal till flowering stage and quite conspicuous afterwards; stems
showed a reverse pattern of variation. Sulphur content was higher at the polluted site in all the organs and at each stage
of the plant life. The Zn and Fe concentrations were reduced in all plant parts under the pollution stress. Copper content
in root was consistently low at the polluted site. In the stem and leaves, however, it was almost equal on both the sites
at the pre-flowering stage but showed a wide difference during the later part of plant ontogeny. 相似文献

Object recognition can break down in a variety of ways after brain damage. The resulting different forms of agnosia provide us with useful constraints on theories of normal object recognition. Recent studies suggest a division of labor for the recognition of different types of stimuli (common objects, words, faces, direction of eye gaze, spatial relations among parts of the human body), a high degree of interactivity in the processes underlying object recognition, and the possibility that recognition and awareness of recognition may be neurally distinct. 相似文献

Street dust samples from urban and suburban areas were collected from the city of Karak, Jordan, during the summer season of 2004. Samples were analyzed for their heavy metal concentrations (Pb, Cu, Zn, Ni, Fe, Cr, Cd, and Mn). The results showed that all heavy metals are higher in city urban areas than the surrounding suburbs. The distribution and concentrations of heavy metals in all areas show automobile originated sources such as emissions and wear and tear of automobiles were the main source of pollution. Despite the fact that the city of Karak and the capital Amman are under the same climatic conditions and same type of fuel used in both cities, the heavy metal concentrations of street dust samples were lower in Karak than Amman due to the lower traffic density. 相似文献
