Clinical impact of tamsulosin on generic and symptom-specific quality of life for benign prostatic hyperplasia patients: Using international prostate symptom score and Rand Medical Outcomes Study 36-item Health Survey

AIM: To examine the efficiency of alpha1-blocker treatment on disease-specific and generic quality of life (QOL) in men with clinically diagnosed benign prostatic hyperplasia (BPH), the improvement of QOL scores with International prostate symptom score (I-PSS) and Rand Medical Outcomes Study 36-item Health Survey (SF-36) was prospectively analyzed. METHODS: A total of 68 newly diagnosed patients with symptomatic BPH that satisfied all inclusion and none of the exclusion criteria were prospectively recruited. All patients received 0.2 mg/day of tamsulosin for 12 weeks. All patients underwent pretreatment documentation of lower urinary tract symptoms (LUTS) and assessment of symptom-specific QOL. Symptoms and general health-related QOL (HRQOL) were assessed using the I-PSS and SF-36, respectively. Also, other objective variables, such as prostate volume, maximal urinary flow and postvoid residual urine volume, were evaluated. RESULTS: After 12 weeks, decrease in I-PSS was 27% compared with baseline (from 16.4 +/- 7.18 to 11.9 +/- 7.56). All questionnaires in the I-PSS showed improvement after tamsulosin treatment and the I-PSS QOL score was improved from 4.51 +/- 1.14 to 3.17 +/- 1.38 (P < 0.0001) at 12 weeks after tamsulosin administration. In intragroup comparisons of HRQOL scores with age-gender adjusted SF-36 Japanese national norms, three SF-36 subscales (bodily pain, BP; social function, SF; and mental health, MH) were worse in the BPH group aged over 70 years, while younger BPH groups aged <70 had better mean SF-36 physical function (PF) scores compared with age-gender adjusted Japanese national norms. In the BPH group with a prostatic volume > or =20 mL, three mean SF-36 scales (BP, SF and MH) were significantly improved after tamsulosin treatment. It is noteworthy that these SF-36 subscales were identical to those observed to worsen in the older BPH group compared to Japanese national norms. CONCLUSIONS: Treatment with tamsulosin for symptomatic BPH patients is associated with significant improvement in the generic HRQOL, in addition to disease-specific QOL and symptoms, at 3 months after drug administration. In particularly, for generic HRQOL with SF-36, tamsulosin treatment can efficiently improve three mean SF-36 subscales (BP, SF and MH) that are decreased in older BPH patients.     

A prospective study of changes in the quality of life of patients following mitral valve repair and replacement.

OBJECTIVE: The primary aim of medical care and surgery for mitral valve disease is to improve the overall functional capacity and health of patients. AIM: To assess whether there was an actual improvement in quality of life (QOL) of patients 3 months following primary mitral valve repair (MRr) or mitral valve replacement (MVR). METHODS: Prospective study of 61 consecutive patients (34 males, mean age 64+/-12) who underwent primary, isolated mitral valve repair (MRr, n=40) or mitral valve replacement (MVR, n = 21) from April 1997 to October 1998. QOL parameters using the validated short form 36 (SF-36) questionnaire were determined before and at 3 months after surgery and analysed using the Wilcoxon matched pairs rank test. RESULTS: Mean QOL scores (scale 0-100) for all patients following mitral valve surgery showed clinical and statistically significant improvement in seven of eight QOL parameters, namely (i) physical function (post, 60+/-31 vs. pre, 44+/-29; P = 0.0001); (ii) role limitation due to physical function (50+/-42 vs. 23+/-36; P = 0.0002); (iii) social function (76+/-31 vs. 59+/-36; P = 0.0006); (iv) role limitation due to emotional problems (65+/-42 vs. 44+/-45; P = 0.003); (v) energy (57+/-24 vs. 40+/-24; P < 0.0001); (vi) mental health (73+/-20 vs. 66+/-21; P = 0.007); and (vii) general health perception (68+/-19 v 56+/-22; P = 0.0001); but not pain (73+/-29 v 71+/-30; P = 0.4). Following MRr there was significant improvement in seven of eight QOL parameters and following MVR there was significant improvement in three of eight QOL parameters. Whilst patients with ejection fraction > or = 50% showed significant improvement in seven of eight QOL parameters, there was no significant improvement in any QOL parameters in patients with impaired left ventricular (LV) function. Similarly, patients with mitral regurgitation with end-systolic dimensions of > or = 45 mm showed no significant improvement in any QOL parameters at 3 months follow-up. CONCLUSIONS: Our study suggests that following mitral valve surgery there was significant improvement in the QOL of patients especially in those patients requiring mitral valve repair. However, patients with impaired LV function and those with MR with end-systolic dimensions > or = 45 mm were unlikely to demonstrate a significant improvement in QOL at 3 months follow-up.     

Long-term detrimental effect of bile duct injury on health-related quality of life

HYPOTHESIS: Long-term quality of life (QOL) in patients undergoing laparoscopic cholecystectomy (LC) incurring bile duct injury (BDI) and repair is comparable to that of patients undergoing uncomplicated LC. DESIGN: Case comparison study. SETTING: Secondary and tertiary care centers. PATIENTS: Eighty-six patients incurring BDI during LC between January 1, 1991, and July 31, 2003, were surveyed. Comparison subjects underwent uncomplicated LC during the same period. MAIN OUTCOME MEASURES: Health-related QOL as assessed by the Karnofsky Performance Scale, Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and Psychosocial Adjustment to Illness Scale. RESULTS: Fifty patients with BDI (39 [78%] female; mean +/- SEM age, 55 +/- 2 years) and 74 patients with uncomplicated LC (51 [69%] female, mean +/- SEM age, 52 +/- 2 years) responded. Of the 50 BDI patients, 48 (96%) had no stricture and normal liver function at QOL assessment. The mean +/- SEM follow-up period to QOL assessment for the BDI and uncomplicated LC groups was 62 +/- 6 and 47 +/- 3 months, respectively. The mean +/- SD Karnofsky Performance Scale scores were 77 +/- 9 vs 93 +/- 8 for the 2 groups, respectively (P <.001). The mean +/- SD SF-36 physical component scale scores after BDI vs uncomplicated LC were 36 +/- 11 vs 47 +/- 12, respectively (P <.001), compared with 50 +/- 10 for the normal population (P <.001). The mean +/- SD SF-36 mental component scale scores were 43 +/- 14 vs 49 +/- 11 for the 2 groups, respectively (P =.02), compared with 50 +/- 10 for the normal population (P =.01). Patients with BDI scored poorer on the Psychosocial Adjustment to Illness Scale health care orientation and domestic environment scales (P=.01). CONCLUSION: After BDI and repair, there are long-term detrimental effects of BDI on health-related QOL.     

Health-related quality of life after different types of solid organ transplantation

OBJECTIVE: To describe functional health and health-related quality of life (QOL) before and after transplantation; to compare and contrast outcomes among liver, heart, lung, and kidney transplant patients, and compare these outcomes with selected norms; and to explore whether physiologic performance, demographics, and other clinical variables are predictors of posttransplantation overall subjective QOL. SUMMARY BACKGROUND DATA: There is increasing demand for outcomes analysis, including health-related QOL, after medical and surgical interventions. Because of the high cost, interest in transplantation outcomes is particularly intense. With technical surgical experience and improved immunosuppression, survival after solid organ transplantation has matured to acceptable levels. More sensitive measures of outcomes are necessary to evaluate further developments in clinical transplantation, including data on objective functional outcome and subjective QOL. METHODS: The Karnofsky Performance Status was assessed objectively for patients before transplantation and up to 4 years after transplantation, and scores were compared by repeated measures analysis of variance. Subjective evaluation of QOL over time was obtained using the Short Form-36 (SF-36) and the Psychosocial Adjustment to Illness Scale (PAIS). These data were analyzed using multivariate and univariate analysis of variance. A summary model of health-related QOL was tested by path analysis. RESULTS: Tools were administered to 100 liver, 94 heart, 112 kidney, and 65 lung transplant patients. Mean age at transplantation was 48 years; 36% of recipients were female. The Karnofsky Performance Status before transplantation was 37 +/- 1 for lung, 38 +/- 2 for heart, 53 +/- 3 for liver, and 75 +/- 1 for kidney recipients. After transplantation, the scores improved to 67 +/- 1 at 3 months, 77 +/- 1 at 6 months, 82 +/- 1 at 12 months, 86 +/- 1 at 24 months, 84 +/- 2 at 36 months, and 83 +/- 3 at 48 months. When patients were stratified by initial performance score as disabled or able, both groups merged in terms of performance by 6 months after liver and heart transplantation; kidney transplant patients maintained their stratification 2 years after transplantation. The SF-36 physical and mental component scales improved after transplantation. The PAIS score improved globally. Path analysis demonstrated a direct effect on the posttransplant Karnofsky score by time after transplantation and diabetes, with trends evident for education and preoperative serum creatinine level. Although neither time after transplantation nor diabetes was directly predictive of a composite QOL score that incorporated all 15 subjective domains, recent Karnofsky score and education level were directly predictive of the QOL composite score. CONCLUSIONS: Different types of transplant patients have a different health-related QOL before transplantation. Performance improved after transplantation for all four types of transplants, but the trajectories were not the same. Subjective QOL measured by the SF-36 and the PAIS also improved after transplantation. Path analysis shows the important predictors of health-related QOL. These data provide clearly defined and widely useful QOL outcome benchmarks for different types of solid organ transplants.     

Quality of life after organ transplantation in type 1 diabetics with end-stage renal disease

Quality of life (QOL) should be an important consideration while choosing therapeutic options for patients with type 1 diabetes mellitus (DM) and end-stage renal disease (ESRD) including dialysis, cadaver (CKT) or living kidney transplant (LKT) or simultaneous pancreas-kidney (SPK) transplant. METHODS: QOL was assessed in four groups of patients with history of type 1 DM and ESRD: recipients of SPK (n = 43), CKT (n = 43), LKT (n = 11) and wait listed (WL) patients (n = 23). Diabetes Quality of Life (DQOL), Short Form-36 (SF-36) and Quality of Well-Being (QWB) questionnaires were utilized. A subset of SPK (n = 19) and CKT (n = 12) recipients underwent longitudinal QOL evaluation. RESULTS: On DQOL questionnaire, SPK group had better satisfaction subscore compared with CKT (1.8 +/- 0.5 vs. 2.2 +/- 0.6, p < 0.01) LKT (1.8 +/- 0.5 vs. 2.4 +/- 0.7, p < 0.05) and WL (1.8 +/- 0.5 vs. 2.6 +/- 0.6, p < 0.001) groups and better impact subscore compared with CKT (1.7 +/- 0.6 vs. 2.1 +/- 0.6, p < 0.05) and WL (1.7 +/- 0.6 vs. 2.3 +/- 0.6, p < 0.01) groups. There were no significant differences on physical/mental composite scores of SF-36. QWB score was better in SPK group vs. WL group (0.62 +/- 0.11 vs. 0.55 +/- 0.04, p < 0.05). Longitudinal decline in satisfaction (2.3 +/- 0.5 vs. 2.6 +/- 0.9, p = 0.058) and impact (2.0 +/- 0.5 vs. 2.2 +/- 0.5, p = 0.019) subscores of DQOL were noted in CKT group. There were no significant changes in the composite scores of SF-36 in both groups. QWB scores declined in the CKT group (0.67 +/- 0.10 vs. 0.61 +/- 0.05, p = 0.01). CONCLUSION: QOL was better in type 1 diabetics with ESRD following transplantation when compared with remaining on WL. SPK transplantation had significant positive effect on diabetes-related QOL which was sustained longitudinally but it was difficult to show an overall improvement in general QOL.     

Prospective decision analysis for peripheral vascular disease predicts future quality of life

OBJECTIVE: Decision making for peripheral vascular disease can be quite complex as a result of pre-existing compromise of patient functional status, anatomic considerations, uncertainty of favorable outcome, medical comorbidities, and limitations in life expectancy. The ability of prospective decision-analysis models to predict individual quality of life in patients with lower extremity arterial occlusive disease was tested. METHODS: This was a prospective cohort study. The settings were university and Veterans Administration vascular surgery practices. All 214 patients referred with symptomatic lower extremity arterial disease of any severity over a 2-year period were screened, and 206 were enrolled. A Markov model was compared with standard clinical decision-making. Utility assessment and generalized (Short Form-36; SF-36) and disease-specific (Walking Impairment Questionnaire; WIQ) quality of life were derived before treatment. Estimates of treatment outcome probabilities and intended and actual treatment plans were provided by attending vascular surgeons. The main outcome measures were generalized (SF-36) and disease-specific (WIQ) variables at study entry and at 4 and 12 months. RESULTS: Primary intervention consisted of amputation for 9, bypass for 42, angioplasty for 8, and medical treatment for 147 patients. Considering all patients, no improvement in mean overall patient quality of life measured by the SF-36 Physical Component Score (27 +/- 8 vs 28 +/- 8; P = .87) or WIQ (39 +/- 22 vs 39 +/- 23; P = .13) was noted 12 months after counseling and treatment by the vascular surgeons. Individually considered SF-36 categories were improved only for Bodily Pain (40 +/- 23 vs 49 +/- 25; P = .03), with the most significant improvement observed among patients with the most severe pain (68 +/- 25 vs 37 +/- 23; P = .02) and among those undergoing bypass (60 +/- 29 vs 31 +/- 22; P = .02). It is noteworthy that when the treatment chosen was incongruent with the Markov model, patients were more likely to report a poorer quality of life at 1 year (Physical Component Score, 25 +/- 8 vs 29 +/- 8; P < .001). The quality of life predicted at baseline by the Markov model correlated positively with the Physical Component Score (r = 0.23), Bodily Pain (r = 0.33), and Fatigue (r = 0.44) and negatively with WIQ (r = -0.08) observed 1 year later. CONCLUSIONS: Prospective application of an individualized decision Markov model in patients with vascular disease was predictive of patient quality of life at 1 year. The patient's outcome was worse when the treatment received did not follow the model's recommendation. This decision analysis model may be useful to identify patients at risk for poor outcomes with standard clinical decision making.     

Switching from cyclosporine to tacrolimus leads to improved disease-specific quality of life in patients after kidney transplantation

BACKGROUND: Advances in transplantation medicine are linked to improved efficacy of immunosuppressive agents. At the same time, these agents endanger medical success by side effects that may impair survival and quality of life (QOL). This study examined whether conversion to tacrolimus-based immunosuppression due to cyclosporine-related side effects improved. QOL in patients after kidney transplantation. METHODS: In total 64 patients (29 men) with an average age of 51 years (SD+/-12) who had received a kidney allograft an average of 5.6 years (SD+/-4) before conversion participated. The reasons for conversion were cardiovascular/metabolic (n=26) or periodontal/dermatological side effects (n=38) of cyclosporine therapy. QOL was assessed before conversion and in average 7 months thereafter by a global (SF-36) and a disease-specific instrument (ESRD-SCL). RESULTS: Disease-specific QOL (ESRD-SCL, global index) improved significantly (P<.001, explanation of variance [EV]=16.6%) after conversion from cyclosporine to tacrolimus. In detail, cardiac and renal dysfunction (P<.01, EV=12.9%) as well as increased growth of gum and hair (P<.0001, EV=53.2%) were significantly reduced at end of the study. However, global QOL (SF-36) remained unchanged. CONCLUSION: Regardless of the indication (cardiovascular or cosmetic), switching to tacrolimus due to cyclosporine-related side effects improved disease-specific QOL within the short term.     

MELD fails to measure quality of life in liver transplant candidates.

Previous studies have demonstrated an association between Child Turcotte-Pugh (CTP) class and impaired quality of life. However, the relationship between the model for end-stage liver disease (MELD) score and quality of life (QOL) has not been well studied. In this study, quality of life questionnaires (Medical Outcomes Short Form 36 [SF-36] and the Chronic Liver Disease Questionnaire [CLDQ]) were administered to 150 adult patients awaiting liver transplantation. We also collected demographic data and laboratory results and recorded manifestations of hepatic decompensation. The study found that all domains of the SF-36 and CLDQ were significantly lower in our patient cohort than in normal controls (P < .001). There was a moderate negative correlation between CPT class and physical components of the SF-36 (r = -.30), while there was a weak negative correlation (r = -.10) between CPT class and the mental component. There was a negative moderate correlation between CPT class and overall CLDQ (r = -.39, P < .001) and a weak correlation (r = -.20) between MELD score and overall CLDQ score. Both encephalopathy (correlation coefficient = -.713, P = .004) and ascites (correlation coefficient = -.68, P = .006) were predictive of the QOL using CLDQ (adjusted R(2) = .1494 and f = 0.000). In conclusion, in liver transplant candidates, the severity of liver disease assessed by the MELD score was not predictive of QOL. The presence of ascites and/or encephalopathy was significantly associated with poor quality of life. CTP correlates better to QOL, probably because it contains ascites and encephalopathy.     

Effects of diabetes and cadaveric organs on functional performance and health-related quality of life after kidney transplantation

BACKGROUND: The current study was undertaken to identify factors specific to kidney transplantation that are associated with posttransplant functional performance (FP) and health-related quality of life (HRQOL). METHODS: Karnofsky FP status was assessed longitudinally in 86 adult kidney transplant recipients. Patients reported HRQOL using the Short Form-36 (SF-36) health survey and the Psychosocial Adjustment to Illness Scale (PAIS). RESULTS: FP improved (P <0.001) after kidney transplantation (from 75 +/- 1 to 77 +/- 1, 81 +/- 1, and 82 +/- 1 at 0, 3, 6, and 12 months, respectively). Patients receiving organs from living donors showed continued improvement through posttransplant year 1 while those receiving cadaveric organs stabilized at month 6 (simple interaction contrast, year 1 versus pretransplant; P <0.05). Patients receiving dialysis therapy for 6 months or more prior to transplantation demonstrated lower SF-36 posttransplant physical component scores in comparison with patients who were transplanted preemptively (38 +/- 1 versus 45 +/- 2, P <0.05). Path analysis demonstrated the positive direct effect of time on FP with kidney transplantation (beta = 0.23, P <0.05), and the negative direct effects on FP of diabetes (beta = -0.22) and cadaveric organs (beta = -0.22, both P <0.05). In turn, FP had a positive direct effect on HRQOL (beta = 0.40, P <0.001). CONCLUSIONS: Overall improvement in FP is attenuated 1 year after kidney transplantation in recipients of organs from cadaveric donors. The positive effect of time after transplantation, and the negative effects of cadaveric organs and diabetes on posttransplant HRQOL, are indirect and are mediated by the direct effects of these variables on posttransplant FP.     

Changes in Quality of Life After Balloon Treatment Followed by Gastric Banding in Severely Obese Patients—The Use of Two Different Quality of Life Questionnaires

Background  Improvements in quality of life (QOL) obtained by weight loss have mainly been reported after bariatric surgery. QOL has not been investigated in surgical patients first losing weight by nonsurgical means followed by a surgical intervention and never simultaneously by two QOL—a generic and a disease-specific—questionnaires. Methods  Prospective data were obtained from 40 consecutive patients (mean age 36.6 years, body weight 142.4 kg, body mass index (BMI) 46.5 kg/m²). Two different QOL questionnaires, the generic Medical Outcomes Study Short Form-36 (SF-36) and the disease-specific Health-Related Quality of Life (HRQL) questionnaire, were evaluated at three points in time: at the start, 3 months after the placement of an intragastric balloon that remained in situ for 6 months, and 3 months after subsequent gastric banding. Results  QOL scores revealed a significant improvement in many health domains, with an earlier improvement with the disease-specific HRQL, whereas the generic QOL questionnaire lagged behind. However, in the end, the SF-36 caught up completely to normal-weight levels, whereas some scales of the HRQL remained below these levels. Work productivity and involvement in sports improved significantly. BMI declined significantly over time, but no correlation with SF-36 and HRQL score changes was found. Conclusion  The QOL improved substantially independent of changes in BMI. Because of the divergent outcomes of generic and disease-specific QOL questionnaires, prospective studies should examine the sensitivity to changes of both kinds of QOL questionnaires.     

Palatal implants for the treatment of snoring and obstructive sleep apnea/hypopnea syndrome.

OBJECTIVE: Randomized, double-blinded, placebo-controlled, clinical trial to determine the effectiveness of palatal implants for treatment of mild/moderate obstructive sleep apnea/hypopnea syndrome (OSAHS). STUDY DESIGN AND SETTING: Sixty-two non-obese adults with history of snoring, daytime sleepiness, and mild/moderate OSAHS, were randomized to receive palatal implants (n = 31) or placebo procedure (n = 31). Complete follow-up including quality of life (QOL, SF-36), snoring visual analog scale (VAS), and Epworth Sleepiness Scale (ESS) data were obtained in 62 patients. Seven patients refused follow-up polysomnography for a total of 55 patients (29 implant and 26 placebo). RESULTS: The treatment group (change in score of -7.9 +/- 7.7) was significantly improved compared with the placebo group (change in score of 0.9 +/- 4.3) for apnea/hypopnea index (AHI) (P < 0.0001), QOL, SF-36 (P < 0.0001), snoring VAS (P < 0.0001), and ESS (P = 0.0002). CONCLUSIONS: Palatal implants improve AHI, QOL, snoring intensity, and daytime sleepiness for selected patients with mild/moderate OSAHS.     

Predictors of success after laparoscopic gastric bypass: a multivariate analysis of socioeconomic factors

Background Laparoscopic gastric bypass (LGB) has proven efficacy in causing significant and durable weight loss. However, the degree of postoperative weight loss and metabolic improvement varies greatly among individuals. Our study is aimed to identify independent predictors of successful weight loss after LGB. Methods Socioeconomic demographics were prospectively collected on patients undergoing LGB. Primary endpoint was percent of excess weight loss (EWL) at 1-year follow-up. Insufficient weight loss was defined as EWL ≤−1 SD from mean EWL. Logistic regression was used in both univariate and multivariate models to identify independent preoperative demographics associated with successful weight loss. Results A total of 180 consecutive patients were enrolled over 30 months. Mean preoperative body mass index (BMI) was 48. Mean EWL was 70.1 ± 17.3% (1 SD); therefore, success was defined as EWL ≥52.8%. According to this definition, 147 patients (81.7%) achieved successful weight loss 1 year after LGB. On univariate analysis, preoperative BMI had a significant effect on EWL, with patients with BMI <50 achieving a higher percentage of EWL (91.7% vs 61.6%; p = 0.001). Marriage status was also a significant predictor of successful outcome, with single patients achieving a higher percentage of EWL than married patients (89.8% vs 77.7%; p = 0.04). Race had a noticeable but not statistically significant effect, with Caucasian patients achieving a higher percentage of EWL than African Americans (82.9% vs 60%; p = 0.06). Marital status remained an independent predictor of success in the multivariate logistic regression model after adjusting for covariates. Married patients were at more than two times the risk of failure compared to those who were unmarried (OR 2.6; 95% CI: 1.1–6.5, p = 0.04). Conclusions Weight loss achieved at 1 year after LGB is suboptimal in superobese patients. Single patients with BMI < 50 had the best chance of achieving greater weight loss.

Do Patients With Diabetes Have Poorer Improvements in Patient-Reported Outcomes After Total Knee Arthroplasty?

BackgroundDiabetes is one of the most common comorbidities in patients undergoing total knee arthroplasty (TKA) for osteoarthritis. However, the evidence remains unclear on how it affects patient-reported outcome measures after TKA.MethodsWe reviewed prospectively collected data of 2840 patients who underwent primary unilateral TKA between 2008 and 2018, of which 716 (25.2%) had diabetes. All patients had their HbA1c measured within 1 month before surgery, and only well-controlled diabetics (HbA1c <8.0%) were allowed to proceed with surgery. Patient demographics and comorbidities were recorded, and multiple regression was performed to evaluate the impact of diabetes on improvements in patient-reported outcome measures (Short Form 36 (SF-36), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Knee Society Score (KSS)) and knee range of motion (ROM).ResultsCompared with nondiabetics, patients with diabetes were more likely to possess a higher body mass index (P-value <.001), more comorbidities (P-value <.001), and poorer preoperative SF-36 Physical Component Summary (PCS) (P-value <.001), WOMAC (P-value = .002), KSS-function (P-value <.001), and knee ROM (P-value <.001). Multiple regression showed that diabetic patients experienced marginally poorer improvements in KSS-knee (?1.22 points, P-value = .025) and knee ROM (?1.67°, P-value = .013) than nondiabetics. However, there were no significant differences in improvements for SF-36 PCS (P-value = .163), Mental Component Summary (P-value = .954), WOMAC (P-value = .815), and KSS-function (P-value = .866).ConclusionPatients with well-controlled diabetes (HbA1c <8.0%) can expect similar improvements in general health and osteoarthritis outcomes (SF-36 PCS and Mental Component Summary, WOMAC, and KSS-function) compared with nondiabetics after TKA. Despite having marginally poorer improvements in knee-specific outcomes (KSS-knee and knee ROM), these differences are unlikely to be clinically significant.     

Quality of life after laparoscopic gastric banding: Prospective study (152 cases) with a follow-up of 2 years

To evaluate influence of laparoscopic gastric banding (LGB) on quality of life (QOL) in patients with morbid obesity. Laparoscopic adjustable gastric banding is a popular bariatric operation in Europe. The objectives of surgical therapy in patients with morbid obesity are reduction of body weight, and a positive influence on the obesity-related comorbidity as well the concomitant psychologic and social restrictions of these patients. In a prospective clinical trial, development of the individual patient QOL was analyzed, after LGB in patients with morbid obesity. From October 1999 to January 2001, 152 patients [119 women, 33 men, mean age 38.4 y (range 24 to 62), mean body mass index 44.3 (range 38 to 63)] underwent evaluation for LGB according the following protocol: history of obesity; concise counseling of patients and relative on nonsurgical treatment alternatives, risk of surgery, psychologic testing, questionnaire for eating habits, necessity of lifestyle change after surgery; medical evaluation including endocrinologic and nutritionist work-up, upper GI endoscopy, evaluation of QOL using the Gastro Intestinal Quality of Life Index (GIQLI). Decision for surgery was a multidisciplinary consensus. This group was follow-up at least 2 years, focusing on weight loss and QOL. Mean operative time was 82 minutes; mean hospital stay was 2.3 days and the mean follow-up period was 34 months. The BMI dropped from 44.3 to 29.6 kg/m and all comorbid conditions improved markedly: diabetes melitus resolved in 71% of the patients, hypertension in 33%, and sleep apnea in 90%. However, 26 patients (17%) had late complications requiring reoperation. Preoperative global GIQLI score was 95 (range 56 to 140), significant different of the healthy volunteers score (120) (70 to 140) P < 0.001. Correlated with weight loss (percentage loss of overweight and BMI), the global score of the group increased to 100 at 3 months, 104 at 6, 111 at 1 year to reach 119 at 2 years which is no significant different of healthy patients. Analyzing the subscale, physical condition, emotional status, and social integration increased significantly (P < 0.001) from preoperative to end of follow-up. Digestive symptoms were not modified. In case of failure of the procedure (10.5%) global Giqli score is not modified. Patients who have required successful revisional surgery for late complications (6.5%) have an excellent QOL outcome that are not different from the whole group. Together with a satisfactory reduction of the excess overweight, laparoscopic gastric banding may lead in a carefully selected population of patients with morbid obesity to a significant improvement of patient QOL, in at least 2 years follow-up.     

Comparison of outcomes after laparoscopic adjustable gastric banding in African-Americans and whites

BACKGROUND: Race may affect outcomes after bariatric surgery. This study compares outcomes in terms of weight loss and comorbidity resolution between African-Americans and whites after laparoscopic adjustable gastric banding (LAGB). METHODS: Data from 959 patients undergoing LAGB between July 2001 and July 2004 were prospectively collected and entered into an electronic registry. Propensity score matching analysis was used to match whites to African-Americans on the basis of age, gender, and preoperative body mass index (BMI). Preoperative comorbidities (diabetes, hypertension, obstructive sleep apnea, hypercholesterolemia, and hypertriglyceridemia) were also compared. Operative time (OR), length of stay (LOS), comorbidity resolution, and percent excess weight loss (%EWL) at 1, 2, and 3 years were analyzed. All data were updated through May 2006. RESULTS: A total of 65 white LAGB patients were matched to 58 African-American LAGB patients on the basis of age, gender, and preoperative BMI. The preoperative mean age and BMI were 37 +/- 19 years and 47 +/- 7 kg/m2, respectively. A total of 55% of the white group and 64% of the African-American group had one or more comorbidities (P = NS). Median OR time and LOS were similar in both groups: 50 minutes and 23 hours, respectively. The majority of patients in both groups had major improvement or resolution of one or more comorbidities (61% whites vs 77% African-Americans, P = NS). There was, however, a significant difference in %EWL between whites and African-Americans at each time interval (49% vs 39% at 1 year; 55% vs 44% at 2 years; 52% vs 41% at 3 years; P < .05 for all values.). CONCLUSION: Despite the disparity in weight loss with the LAGB in African-Americans and whites, both patient populations experienced a similar improvement/resolution of obesity-related comorbidities.     

Self-assessed quality of life in peritoneal dialysis patients.

BACKGROUND/AIMS: Studies comparing quality of life (QOL) between peritoneal and hemodialysis patients have yielded inconsistent results. Physical (PCS) and mental component summary (MCS) scales of Short Form 36 (SF-36) health survey are highly validated measures of self-assessed QOL. We sought to evaluate these indices in PD patients: (1) as measures of QOL, (2) predictors of QOL, (3) to study change in QOL over time, and (4) to compare QOL in PD vs. hemodialysis patients. METHODS: SF-36 questionnaires were administered every 3 months to patients over a 2-year period and PCS and MCS were calculated. Mean follow-up was 15.3 +/- 6.6 months for PD and 14.5 +/- 5.7 months for HD. RESULTS: Average PCS in PD (31.8 +/- 7.8) was lower than HD (36.9 +/- 9.8) (p < 0.02), while MCS was similar in the groups (p = NS). The prevalence of depression was 26.1% in PD and 25.4% in HD patients (p = NS). Serum albumin was the only significant predictor of PCS among PD patients and explained much of the decrease in PCS in them. The number of hospitalizations and in-hospital days were significantly lower for PD compared to HD patients (p < 0.05). PCS as well as MCS remained stable in both groups throughout the observation period. CONCLUSION: Self-assessed physical function is diminished, while mental function is similar in PD compared to HD patients. When corrected for serum albumin, this difference is eliminated. Over time, QOL in patients treated with PD remained stable.     

Effect of medical comorbidity on self-assessed pain, function, and general health status after rotator cuff repair

BACKGROUND: In a previous study, we found that medical comorbidities have a negative effect on preoperative pain, function, and general health status in patients with a chronic rotator cuff tear. In this study, we evaluated the relationship between medical comorbidities and the postoperative outcome of rotator cuff repair. METHODS: One hundred and twenty-five patients were evaluated on the basis of a history (including medical comorbidities) and use of outcome tools preoperatively and at one year after rotator cuff repair. Outcome was evaluated with the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire, the Simple Shoulder Test (SST), visual analog scales (pain, function, and quality of life), and the Short Form-36 (SF-36). RESULTS: The mean number of medical comorbidities was 1.91 (range, zero to six). At one year after rotator cuff repair, there were no significant correlations between comorbidities and pain, shoulder function, or quality of life as determined with the SST, DASH, and visual analog scales (p > 0.05). A greater number of comorbidities was associated with a worse postoperative general health status (SF-36 role emotional [p = 0.045], SF-36 bodily pain [p = 0.032], SF-36 general health [p = 0.001], and SF-36 vitality [p = 0.033]). Nevertheless, a greater number of comorbidities was associated with greater improvement, compared with the preoperative status, in the pain score on the visual analog scale (p = 0.009), function as assessed with the visual analog scale (p = 0.022) and the DASH (p = 0.044), and quality of life as assessed with the visual analog scale (p = 0.041). CONCLUSIONS: Patients with more medical comorbidities have a worse general health status after rotator cuff repair. Interestingly, it also appears that these patients have greater improvement in overall shoulder pain, function, and quality-of-life scores compared with preoperative scores. Therefore, despite a negative effect of comorbidities on outcomes, patients with more comorbidities have greater improvement after the repair, to the point where postoperative shoulder function and pain are not significantly influenced by medical comorbidities. Consequently, a higher number of medical comorbidities should not be considered a negative factor in determining whether a patient should undergo rotator cuff repair.     

Laparoscopic versus open gastric bypass: a randomized study of outcomes, quality of life, and costs

OBJECTIVE: To compare outcomes, quality of life (QOL), and costs of laparoscopic and open gastric bypass (GBP). SUMMARY BACKGROUND DATA: Laparoscopic GBP has been reported to be a safe and effective approach for the treatment of morbid obesity. The authors performed a prospective randomized trial to compare outcomes, QOL, and costs of laparoscopic GBP with those of open GBP. METHODS: From May 1999 to March 2001, 155 patients with a body mass index (BMI) of 40 to 60 kg/m2 were randomly assigned to undergo laparoscopic (n = 79) or open (n = 76) GBP. The two groups were similar in age, sex ratio, mean BMI, and comorbidities. Main outcome measures included operative time, estimated blood loss, length of hospital stay, operative complications, percentage of excess body weight loss, and time to return to activities of daily living and work. Changes in QOL were assessed using the SF-36 Health Survey and the bariatric analysis of reporting outcome system (BAROS). Operative and hospital costs of the two operations were also compared. RESULTS: There were no deaths in either group. Mean operative time was longer for laparoscopic GBP than for open GBP, but operative blood loss was less. Two (2.5%) of the 79 patients in the laparoscopic group required conversion to laparotomy. Median length of hospital stay was shorter for laparoscopic GBP patients (3 vs 4 days). The rate of postoperative anastomotic leak was similar between groups. Wound-related complications such as infection (10.5 vs 1.3%) and incisional hernia (7.9 vs 0%) were more common after open GBP; late anastomotic stricture was less frequent after open GBP (2.6 vs 11.4%). Time to return to activities of daily living and work were shorter after laparoscopic GBP than after open GBP. Weight loss at 1 year was similar between groups. Preoperative SF-36 scores were similar between groups; however, at 1 month after surgery, laparoscopic patients had better physical conditioning, social functioning, general health, and less body pain than open GBP patients. At 6 months, the BAROS outcome was classified as good or better in 97% of laparoscopic GBP patients compared with 82% of open GBP patients. Operative costs were higher for laparoscopic GBP patients, but hospital costs were lower. CONCLUSIONS: Laparoscopic GBP is a safe and cost-effective alternative to open GBP. Despite a longer operative time, patients undergoing laparoscopic GBP benefited from less blood loss, a shorter hospital stay, and faster convalescence. Laparoscopic GBP patients had comparable weight loss at 1 year but a more rapid improvement in QOL than open GBP patients. The higher initial operative costs for laparoscopic GBP were adequately offset by the lower hospital costs.     

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn''s disease

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.
