Sexual Dysfunction After Conventional and Endovascular AAA Repair: Results of the DREAM Trial.

Contains fulltext : 57776.pdf (publisher's version ) (Open Access)Purpose: To assess sexual function in the first postoperative year after elective endovascular aneurysm repair (EVAR) and open repair (OR) of abdominal aortic aneurysm (AAA).Methods: In the Dutch Randomized Endovascular Aneurysm Management (DREAM) trial, 153 patients (141 men; mean age 71 years, range 53-85) were randomly allocated to EVAR (n=77) or OR (n=76). Sexual functioning was evaluated preoperatively and at 5 times in the first postoperative year (3, 6, 13, 26, and 52 weeks) using a questionnaire derived from the Medical Outcomes Study. The proportions of patients reporting sexual dysfunction for any of 5 aspects (interest, pleasure, engagement, orgasm, and erection) and any increase in the magnitude of dysfunction were compared between EVAR and OR.Results: Preoperatively, the proportion of patients reporting sexual dysfunction in at least 1 aspect was 66% for the OR group and 74% in the EVAR group (p=NS). Surgery had a clear impact on sexual dysfunction. The proportion of patients reporting sexual dysfunction on at least 1 aspect increased to 79% in the OR group and 82% in the EVAR group. The magnitude of sexual dysfunction increased in both groups on all 5 aspects at 3 weeks postoperatively, but this was more pronounced in the OR group (interest: OR p=0.038 vs. EVAR p=0.071; pleasure: OR p=0.009 vs. EVAR p=0.065; engagement: OR p=0.006 vs. EVAR p=0.054; orgasm OR p=0.023 vs. EVAR p=0.112, and erection: OR p=0.046 vs. EVAR p=0.030). At 6 weeks, the OR group still reported a significant increase in 3 aspects (pleasure p=0.031, engagement p=0.010, and orgasm p=0.003), whereas the EVAR group no longer showed a significant difference. From 3 months on, both groups had returned to baseline.Conclusions: EVAR and open elective AAA repair both have an impact on sexual function in the early postoperative period. After EVAR, recovery to preoperative levels is faster than after open repair, but at 3 months, sexual dysfunction levels are similar in both groups

Minimally Important Difference of the Absolute and Functional Claudication Distance in Patients with Intermittent Claudication

Item does not contain fulltextOBJECTIVE: Disease severity and treatment outcomes in patients with intermittent claudication (IC) are commonly assessed using walking distance measured with a standardized treadmill test. It is unclear what improvement or deterioration in walking distance constitutes a meaningful, clinically relevant, change from the patients' perspective. The purpose of the present study was to estimate the minimally important difference (MID) for the absolute claudication distance (ACD) and functional claudication distance (FCD) in patients with IC. METHOD: The MIDs were estimated using an anchor based approach with a previously defined clinical anchor derived from scores of the walking impairment questionnaire (WIQ) in a similar IC population. Baseline and 3 month follow up data on WIQ scores and walking distances (ACD and FCD) were used from 202 patients receiving supervised exercise therapy from the 2010 EXITPAD randomized controlled trial. The external WIQ anchor was used to form three distinct categories: patients with "clinically relevant improvement," "clinically relevant deterioration," and "no clinically relevant change." The MIDs for improvement and deterioration were defined by the upper and lower limits of the 95% confidence interval of the mean change in ACD and FCD, for the group of IC patients that remained unchanged according to the WIQ anchor. RESULTS: For the estimation of the MID of the ACD and FCD, 102 and 101 patients were included, respectively. The MID for the ACD was 305 m for improvement, and 147 m for deterioration. The MID for the FCD was 250 m for improvement, and 120 m for deterioration. CONCLUSION: The MIDs for the treadmill measured ACD and FCD can be used to interpret the clinical relevance of changes in walking distances after supervised exercise therapy and may be used in both research and individual care

Gender differences following supervised exercise therapy in patients with intermittent claudication

Item does not contain fulltextOBJECTIVE: Prevalence of peripheral arterial disease is equal in men and women. However, women seem to suffer more from the burden of disease. Current studies on gender-related outcomes following supervised exercise therapy (SET) for intermittent claudication (IC) yield conflicting results. METHODS: A follow-up analysis was performed on data from the 2010 Exercise Therapy in Peripheral Arterial Disease (EXITPAD) study, a multicenter randomized controlled trial including IC patients receiving SET or a walking advice. The SET program was supervised by physiotherapists and included interval-based treadmill walking approximating maximal pain combined with activities such as cycling and rowing. Patients usually started with three 30-minute sessions a week. Training frequency was adapted during the following year on the basis of individual needs. The primary outcome was gender differences regarding the change in absolute claudication distance (ACD) after SET. ACD was defined as the number of meters that a patient had covered just before he or she was forced to stop walking because of intolerable pain. Secondary outcomes were gender differences in change of functional walking distance, quality of life, and walking (dis)ability after SET. Walking distances were obtained by standardized treadmill testing according to the Gardner-Skinner protocol. Quality of life was measured by the 36-Item Short Form Health Survey, and walking (dis)ability was determined by the Walking Impairment Questionnaire (WIQ). Measurements were performed at baseline and after 3, 6, 9, and 12 months. Only patients who met the 12-month follow-up measure were included in the analysis. RESULTS: A total of 113 men and 56 women were available for analysis. At baseline, groups were similar in terms of clinical characteristics and ACD walking distances (men, 250 meters; women, 270 meters; P = .45). ACD improved for both sexes. However, ACD increase was significantly lower for women than for men during the first 3 months of SET (Delta 280 meters for men vs Delta 220 meters for women; P = .04). Moreover, absolute walking distance was significantly shorter for women compared with men after 1 year (565 meters vs 660 meters; P = .032). Women also reported less on several WIQ subdomains, although total WIQ score was similar (0.69 for men vs 0.61 for women; P = .592). No differences in quality of life after SET were observed. CONCLUSIONS: Women with IC benefit less during the first 3 months of SET and have lower absolute walking distances after 12 months of follow-up compared with men. More research is needed to determine whether gender-based IC treatment strategies are required
