The fatality of novel coronavirus disease 2019 (COVID‐19) is precipitously increased in patients with underlying comorbidities or elderly people. Kidney transplant (KT) recipients are one of the vulnerable populations for infection. COVID‐19 infection in KT recipients might be a complicated and awkward situation, but there has been a lack of reports concerning this group. Herein, we demonstrated two distinct cases with different clinical progress. The first case was a 36‐year‐old man who underwent KT 3 years ago. He was diagnosed with COVID‐19 expressing relevant symptoms. Following administration of lopinavir/ritonavir and hydroxychloroquine with reduced immunosuppressant, he recovered from COVID‐19. However, the unexpected fluctuations in tacrolimus trough levels needed to be managed because of drug‐to‐drug interaction. The second case was developed in a 56‐year‐old man without any symptoms. He received a second KT from an ABO‐incompatible donor 8 years ago. He was diagnosed with COVID‐19 by screening due to exposure history. During the hospitalization period, the chest infiltrative lesion showed a wax and wane, but he successfully recovered by administration of hydroxychloroquine with azithromycin. These apparently different cases suggest that assertive screening and management could improve the clinical course. In addition, antiviral agents should be used cautiously, especially in patients on calcineurin inhibitors.
Background: There were a few studies which were conducted to know about the behavior of the chronic obstructive pulmonary diseases (COPD) patients. The aims of this study was to explore the behaviour of COPD patients, such as awareness and impact of disease, the pathway of visiting doctors, and the treatment pattern and preference. Methods: A face-to-face interview of 300 subjects with COPD was conducted. Results: The most concerned symptom which made the respondents to visit the hospital was 'breathlessness' (78%). Only 58% of them knew the exact diagnosis. Seventy-three percent of them visited the hospital 'once a month' or 'once every 2 month'. They have made 12.8 prescheduled visits to the hospital in the past 1 year. Unscheduled visits and hospital stay figured to two in the past year. Only 11% of respondents felt they were currently in good health. 'Severe' and 'very severe' COPD patients perceived their health to be in a worse condition than 'mild' and 'moderate' COPD patients. When conditions worsened, 42% of patients were hospitalized. The most common prescription treatment was a fixed combination of inhaled corticosteroids and long-acting β2 agonists (48%), followed by a long acting anticholinergics (38%). Conclusion: Over forty percent of the patients didn't know exactly about their condition. Most of them had a negative attitude toward their current health status. Doctors need to know more about COPD patients in terms of their attitude toward the disease, impact of the disease, interaction with healthcare professionals and treatment related problems.
A series of centrifuge model tests was conducted to measure the ultimate horizontal bearing capacity of suction piles. Three different pile lengths were tested in sand. Model piles were laterally loaded at different points along the pile length to evaluate the effect of the loading depth on the ultimate horizontal bearing capacity of suction piles. Two tests were conducted for each loading point. Results from centrifuge model tests were then compared with the analytical predictions to determine the validity of the analytical solution in predicting the ultimate horizontal bearing capacity of rigid suction piles loaded at various depths. Predicted values from the analytical solution compared well with the measured values from the centrifuge model tests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
