Background: Recent evidence suggests that increased visceral adiposity is a strong independent risk factor for cardiovascular death and all-cause mortality in hemodialysis (HD) patients. Irisin, which is a novel myokine, can play critical roles in diabetes and adiposity. The purpose of our study was to investigate whether serum irisin levels are associated with body mass index, waist circumference (WC), and total fat mass in non-diabetic patients undergoing maintenance HD.Methods: This cross-sectional study included 108 non-diabetic HD patients and 40 age- and sex-matched apparently healthy subjects. Serum irisin concentrations were determined using an enzyme-linked immunosorbent assay. Body fat composition (TBF-410 Tanita Body Composition Analyzer) was measured and calculated.Results: Serum irisin levels did not differ between HD patients and the healthy controls (523.50?±?229.32 vs. 511.28?±?259.74, p?=?0.782). Serum irisin levels were associated with age (r?=?0.314; p?=0.006), HOMA-IR (r?=?0.472; p?=?0.003), WC (r?=?0.862; p?0.001), and total fat mass (r?=?0.614; p?0.001). In multivariate regression analysis, WC (β?=?1.240, p?0.001) and total fat mass (β?=?0.792, p?=?0.015) were the variables that were significantly associated with irisin concentrations (R2?=?0.684, p?0.001) after adjusting for confounding factors (age and HOMA-IR). Conclusions: These results suggest that serum irisin levels are related to visceral adiposity in non-diabetic HD patients. 相似文献

The relationship between pulmonary function and right ventricle (RV) in Duchenne muscular dystrophy (DMD) has not been evaluated. Using cardiac magnetic resonance (CMR), we describe the relationship of RV size and function with spirometry in a DMD cohort. Fifty-seven boys undergoing CMR and pulmonary function testing within 1 month at a single center (2013–2015) were enrolled. Comparisons of RV ejection fraction (RVEF) and end-diastolic volume index (RVEDVI) were made across categories of percent forced vital capacity (FVC%), and relationships were assessed. Mean age was 15.5 ± 3.5 years. Spirometry and CMR were performed within 3.9 ± 4.1 days. Median FVC% was 92.0 % (67.5–116.5 %). Twenty-three (40 %) patients had abnormal FVC% (<80 %) of which 13 (57 %) had mild (FVC% 60–79 %), 6 (26 %) had moderate (FVC% 40–59 %), and 4 (17 %) had severe (FVC <40 %) reductions. Mean RVEF was 58.3 ± 3.7 %. Patients with abnormal FVC% were older and had lower RVEF and RVEDVI. Both RVEF and RVEDVI were significantly associated with FVC% (r = 0.31, p = 0.02 and r = 0.39, p = 0.003, respectively). In a large DMD cohort, RVEF and RVEDVI were related to FVC%. Worsening respiratory status may guide monitoring of cardiac function in these patients. 相似文献

Nonunion of the humerus in a severely osteoporotic bone is a likely event especially if the fracture is transverse. The management of such a combination is a challenge. Most of the conventional fixation
methods are unlikely to succeed as the bone failure precedes implant failure in osteoporosis. The
challenge is further compounded in severe osteoporosis when the cortical thickness is affected more
severely. We used a combination of an intramedullary fibula with a locking plate in 5 cases. The results show that it may be a good combination in such situations as the bone strength is augmented and the plate pullout is less likely. 相似文献

Immune reconstitution inflammatory syndrome is commonly seen in acquired immunodeficiency syndrome (AIDS) patients having concomitant opportunistic infection, following initiation of highly active anti-retroviral therapy (HAART). We describe IRIS in a young man with unknown human immunodeficiency virus (HIV) status who presented with cryptococcal lymphadenitis as the first manifestation of AIDS. At presentation the patient had features overlapping with tuberculosis (TB) lymphadenitis which was ruled out by fine needle aspiration cytology. The patient responded to antifungal treatment but following the start of HAART, symptoms recurred which were managed conservatively. Though TB is common in India, a thorough workup including histopathology of lymph node should be done before the patient is started on anti-tuberculosis treatment. HIV infected patients having opportunistic co-infection should be closely monitored following initiation of HAART. 相似文献
