OBJECTIVE: Existing literature indicates that the mortality rate with each variceal bleeding episode is 30-50%. Over the past 2 decades, there have been significant developments in the management of variceal bleeding. The effect of these developments on the natural history of variceal bleeding is unclear. Therefore, a retrospective, multicenter study was conducted to define the outcomes of variceal bleeding and to describe the patterns of current practice in the management of variceal bleeding. METHODS: All patients with documented variceal bleeding hospitalized at four large county hospitals from January 1, 1997, to June 30, 2000, were included. Study outcomes were in-hospital, 6-wk, and overall mortality, rate of rebleeding, transfusion requirement, and length of stay. After discharge, patients were followed until death or study closure date, on June 30, 2000. RESULTS: A total of 231 subjects were included, and their in-hospital, 6-wk, and overall mortality rates were 14.2%, 17.5%, and 33.5%, respectively. The frequency of rebleeding during follow-up was 29%. Median length of total hospital stay was 8 days (0-34 days). Median number of packed red cell units transfused was 4 U (0-60 U). Upper endoscopy was performed in 95% of patients within 24 h, and endoscopic therapy was done in all but eight patients (ligation 64%, sclerotherapy 33%). Octreotide was administered in 74% of the patients. Portasystemic shunts were performed in 7.5% of the patients for controlling acute variceal bleeding. CONCLUSIONS: The mortality rate after variceal bleeding in this study was substantially lower than previously reported. This suggests that advances made in the management of variceal bleeding have improved outcomes after variceal bleeding. 相似文献
The aim of this work was to specify the timecourse of response to interferon (IFN) of hepatitis Gvirus (HGV) and hepatitis C virus (HCV) in coinfectedindividuals. A group of 33 patients, undergoing 12 months of IFN therapy for chronic hepatitis C,was screened for the presence of both HGV and HCV RNAsto select seven coinfected patients. Spontaneousrecovery from HGV infection was excluded through the detection of antibodies to the envelope-2protein of HGV and HCV isolates were genotyped. Withinthree months of treatment, we found that HGV RNA wastransiently cleared in 6/7 patients, but the rate of long-term favorable response was very low(1/7). In addition, considering the same individualsseparately, it was shown that HGV and HCV responded toIFN with different kinetics in 5/7 patients. Takentogether, these results underscore the importance of thevirological basis of the resistance to IFNtreatment. 相似文献
OBJECTIVE: To assess the clinimetric properties of a new health-related quality of life (HRQOL) instrument, the World Health Organization Disability Assessment Schedule II (WHODAS II), in patients with early inflammatory arthritis. METHODS: Internal consistency as well as criterion, construct, and discriminative validity of the WHODAS II were assessed in 172 patients with early inflammatory arthritis who completed the WHODAS II, the Medical Outcomes Study Short Form 36 (SF-36), and other measures of disease severity, functioning, pain, depression, and resource use. Test-retest reliability of the WHODAS II was assessed by having a subset of 20 patients complete the WHODAS II a second time, 1 week after the first assessment. RESULTS: The WHODAS II had high internal consistency (Cronbach's alpha = 0.96 for patients working or in school and 0.93 for patients not working or in school). Test-retest intraclass correlation coefficients of the WHODAS II total score and subscales ranged from 0.82-0.96. The WHODAS II total score was strongly correlated with the SF-36 physical component score (Kendall's tau-b 0.51, P < 0.001) and moderately correlated with the SF-36 mental component score (tau-b 0.43, P < 0.001). WHODAS II correlations with disease outcomes ranged from Kendall's tau-b 0.15-0.55. The WHODAS II significantly differentiated between every aspect of disease severity assessed with the exception of measures of health resource use. CONCLUSION: The WHODAS II is a valid and reliable measure of HRQOL in cross-sectional studies of patients with early inflammatory arthritis. Research is still required to investigate potential item redundancy and determine its usefulness in longitudinal studies. 相似文献

Purpose: To determine improvements in goal satisfaction following individualized mobility-related powered wheelchair skills training and whether changes in satisfaction are maintained 3 months post-training.Materials and methods: Seventeen powered wheelchair users, from two centres, who were randomized to the training intervention from a larger multicentre study, were included in this secondary analysis. The intervention consisted of five 30-min individualized Wheelchair Skills Training Program sessions. Participants rated their current satisfaction with each of their goals from 0 to 10 (10 being the highest) prior to training, immediately after the intervention, and approximately 3 months following the intervention. Themes relating to the participants’ goals were also explored.Results: Goal satisfaction scores improved statistically (p?.001) from baseline (4.7?±?1.9) to immediately following training (8.0?±?1.0) and were maintained 3 months (8.3?±?1.2) following the intervention. Participants’ goal satisfaction scores were not significantly correlated with goal attainment scores recorded by the trainer (r?=?0.387, n?=?17, p?=?.125). The majority of goals set fell into the broader “manoeuvring” category.Conclusion: Goal satisfaction following the Wheelchair Skills Training Program improved years after initially learning how to operate a powered wheelchair. The five training sessions were effective in improving goal satisfaction. The quantification of goal satisfaction appears to be a sensitive outcome for powered wheelchair users undergoing mobility-related training.
Implications for rehabilitation
Goal satisfaction improved following the Wheelchair Skills Training Program.
Even with years of powered wheelchair experience, the majority of goals set fell into the broader “manoeuvring” category.
An individual’s goal satisfaction may not correlate with whether they have attained their goal as determined by a trainer.
Purpose: The purpose of this study was to systematically examine the effect of an 8-week controlled whole-body vibration training on improving fall risk factors and the bone mineral density among people with multiple sclerosis (PwMS).
Methods: This study adopted a single group pre-test–post-test design. Twenty-five PwMS (50.3 years SD 14.1) received vibration training on a side-alternating vibration platform. Each training session was repeated three times every week for 8 weeks. Prior to and following the 8-week training course, a battery of fall risk factors were evaluated: the body balance, functional mobility, muscle strength, range of motion, and fear of falling. Bone density at both calcanei was also assessed.
Results: Twenty-two participants completed the study. Compared with pre-test, almost all fall risk factors and the bone density measurement were significantly improved at post-test, with moderate to large effect sizes varying between 0.571 and 1.007.
Conclusions: The 8-week vibration training was well accepted by PwMS and improved their fall risk factors. The important findings of this study were that vibration training may increase the range of motion of ankle joints on the sagittal plane, lower the fear of falling, and improve bone density.
IMPLICATIONS FOR REHABILITATION
An 8-week vibration training course could be well-accepted by people with multiple sclerosis (MS).
Vibration training improves the risk factors of falls in people living with MS.
Vibration training could be a promising rehabilitation intervention in individuals with MS.
