Deficient sleep quality (sQ) has been linked with a higher hospitalization rate and mortality in dialysis patients, however the prevalence of sleep disorders and their influence on prognosis in non-dialysis chronic kidney disease (CKD) has been poorly investigated. The aim of this study was to assess factors related with sQ in CKD patients (stages I-IV) followed in a nephrology outpatient clinic as well as the long-term impact of sQ on patient’s outcome. Between January and May 2008, Pittsburgh sleep Quality Index (PsQI) was self-administered by 122 patients (68 males and 54 females) with a mean age of 65 years. Patients were classified as “good” (global PsQI oor” sleepers (global PsQI ≥ 6). We identified 66 (54%) poor sleepers (Ps), characterized by an older age (66 ± 14.2 vs 57 ± 17.0, p ominance (59% vs 26%, p orse renal function (49 ± 19.1 vs 57 ± 23.2 ml/min, p s a significant correlation between phosphate and PsQI score (r = 0.234, p = 0.01), however no correlation with calcium or PTH. Vitamin D was also lower in Ps (17 ± 7.2 vs 23 ± 15.1 ng/ml, p ospitalization rate was higher among Ps (64% vs 44%, p s period, there was also a trend towards higher mortality for Ps (18% vs 16%). In summary, over 50% of CKD patients have poor sQ, which was associated with older age, female gender, worse renal function, lower vitamin D and higher phosphate levels. Deficient sleep was associated with a greater probability of hospitalization and might be a prognostic marker in CKD.

Rotating effects on the photoionization cross-section of a 2D quantum ring

引用

Communications in Theoretical Physics 2024年第10期76卷 153-159页

作者： Carlos Magno o Pereira Frankbelson dos s Azevedo Luís Fernando C Pereira Edilberto o silva Departamento de Física Universidade Federal do Maranh?o

In this article, we investigate the nonrelativistic quantum motion of a charged particle within a rotating frame, taking into account the Aharonov–Bohm(AB) effect and a uniform magnetic field. our analysis entails the derivation of the equation of motion and the corresponding radial equation to describe the system. solving the resulting radial equation enables us to determine the eigenvalues and eigenfunctions, providing a clear expression for the energy levels. Furthermore,our numerical analysis highlights the substantial influence of rotation on both energy levels and optical properties. specifically, we evaluate the photoionization cross-section with and without the effects of rotation. To elucidate the impact of rotation on the photoionization process of the system, we present graphics that offer an appealing visualization of the intrinsic nature of the physics involved.
