Objectives: Phase angle (PA) is a poor prognostic factor in patients with advanced cancer. This study aimed to identify possible correlations between PA and symptoms, quality of life, fluid retention, and laboratory data in cancer patients in palliative care settings.
Methods: Individuals who visited the outpatient clinic or were admitted to the palliative care unit were eligible. Patients with a performance status of 4 and/or those unable to complete questionnaires were excluded. PA was evaluated using a bioanalyzer device. The correlation coefficient between PA and the variables of interest was analyzed.
Results: A total of 102 patients were analyzed. PA was weakly correlated with age (ρ = ?0.22), performance status (ρ = ?0.30), functional well-being (ρ?=?0.20), anorexia/cachexia subscale (ρ?=?0.22), and Functional Assessment of Anorexia/Cachexia Therapy trial outcome index (ρ?=?0.26). PA was also correlated with fluid retention (ρ = ?0.34) and albumin (ρ?=?0.32), C-reactive protein (ρ = ?0.31), and hemoglobin (ρ?=?0.41) levels. Sub-analysis stratified according to sex revealed that males demonstrated the same results; however, female sex demonstrated a correlation between PA and social well-being (ρ = ?0.43).
Conclusions: PA was correlated with physical condition, but not with psychological well-being. 相似文献
Immunoglobulin (Ig) G4‐related disease has various clinical signs and symptoms, and steroidal therapy with corticosteroids has been found to be effective for treatment. Few cases of IgG4‐related disease associated with paravertebral tumor have been reported, and there have been no reports on complete resection of such a tumor. Here, we report a case of IgG4‐related disease associated with a paravertebral tumor that was successfully resected without the need for postoperative medication. An 84‐year‐old woman was admitted to our hospital with a paravertebral tumor. She underwent thoracoscopic surgery, and pathological examination of the tumor specimen revealed that the tumor resulted from IgG4‐related disease. After resection, there was no need for postoperative medication. Our case indicates the rare possibility of a paravertebral tumor associated with IgG4‐related disease and the potential for complete resection as a treatment for such a tumor. 相似文献
Biliary secretion of bile acids and phospholipids, both of which are essential components of biliary micelles, are mediated by the bile salt export pump (BSEP/ABCB11) and multidrug resistance 3 P-glycoprotein (MDR3/ABCB4), respectively, and their genetic dysfunction leads to the acquisition of severe cholestatic diseases. In the present study, we found two patients with itraconazole (ITZ)-induced cholestatic liver injury with markedly high serum ITZ concentrations. To characterize the effect of ITZ on bile formation in vivo, biliary bile acids and phospholipids were analyzed in ITZ-treated rats, and it was revealed that biliary phospholipids, rather than bile acids, were drastically reduced in the presence of clinically relevant concentrations of ITZ. Moreover, by using MDR3-expressing LLC-PK1 cells, we found that MDR3-mediated efflux of [1?C]phosphatidylcholine was significantly reduced by ITZ. In contrast, BSEP-mediated transport of [3H]taurocholate was not significantly affected by ITZ, which is consistent with our in vivo observations. In conclusion, this study suggests the involvement of the inhibition of MDR3-mediated biliary phospholipids secretion in ITZ-induced cholestasis. Our approach may be useful for analyzing mechanisms of drug-induced cholestasis and evaluating the cholestatic potential of clinically used drugs and drug candidates. 相似文献
Background Tapered femoral stems have been shown to produce less thigh pain and stress shielding than other cement-less stem designs.
The purpose of this study was to examine the performance of this type of femoral stem in Japanese patients.
Methods A series of 40 total hip arthroplasties with a Synergy tapered femoral component were performed in 33 patients between March
1999 and February 2001 at our institution. Three hips (in three patients) were lost to follow-up, so 37 hips in 30 patients
were followed for an average of 70 months. The patients’ average age at the time of surgery was 59 years (range 43–80 years).
Clinical evaluation included the Japanese Orthopaedic Association (JOA) Hip Score and the incidence of thigh pain. Preoperative
radiographic examination included the cortical index and Dorr’s bone type. Postoperative radiographic examination included
evaluation of biological fixation, spot welds, cortical hypertrophy, and stress shielding.
Results The average JOA Hip Score improved significantly from 35 preoperatively to 91 postoperatively. No patient suffered thigh pain.
All femoral components were classified as bony stable. Spot welds and cortical hypertrophy were commonly found in the middle
to the distal portion of the component. Severe (third and fourth degree) stress shielding was observed in 24.3% of the cases.
A low cortical index, a Dorr type C femur, and a large stem size were associated with severe stress shielding.
Conclusions The midterm clinical results with the Synergy femoral component were satisfactory for Japanese patients. Although severe stress
shielding was frequently observed in patients with poor bone quality, stem stability was not affected. Extent of grit blasting
and stem length may be factors causing severe stress shielding in Japanese patients with poor bone quality. In conclusion,
poor bone quality is a less favorable indication for the cementless tapered stem. 相似文献
In Japan, it is required to measure the hydrogen sulfide (H2S) concentration before sewerage work can commence, in order to prevent toxic accidents caused by H2S. The actual H2S concentration of the sewerage hole is often different from that initially measured, and there is often a more than fatal concentration because of rapidly volatilizing H2S. However, no countermeasures for this have been developed, nor has any system for the measurement of the H2S held in sewerage water and sludge been established yet. In this paper, therefore, the measurement of H2S dissolved in water was investigated, and the actual form of the H2S held in the water and the sludge was analyzed. Prevention measures against toxic accidents were also investigated. Water and sludge were collected from an actual sewerage hole, and the quantities of H2S held in them were measured by the new method with the stripping which we developed. We also determined the quantity of H2S volatilized from the water surface during work, and estimated the change of air quantity necessary to reduce the concentration of H2S to a safety level for workers. As a result, it was shown that even if the H2S concentration of the gas phase before the work is regarded as at a safety level for workers, they may be in an extremely dangerous situation resulting from the rapid volatilization of H2S during their work.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
