Echocardiographic findings in former professional cyclists after long-term deconditioning of more than 30 years.

BACKGROUND: In professional cyclists, typical changes include reversible dilatation of atria and left ventricle (LV), LV hypertrophy but normal diastolic function. Data on long-term outcome are limited. METHODS: Of all 134 former Swiss professional cyclists (PC) participating >or=1x in the professional bicycle race Tour de Suisse from 1955 to 1975, 62 (42%) were recruited for a prospective case control study. The PC and a control group of 62 golfers (matched for age, gender, hypertension, present physical activity) were screened [clinical examination, history, echocardiography, measurement of proBNP (normal <227 pg/mL)]. RESULTS: The interval since the last bicycle race as PC was 38 (15-49) years. Average age at exam was equal in controls and PC (66+/-6 vs 66+/-7 years; P = 0.73). Percentage of participants undergoing >4 h of endurance training per week was identical (P = 0.72). Total kilometers (km) on the bicycle were higher in PCs with 311,000 (60,000-975,000) than in controls (2500 [0-120,000]; P < 0.0001). PC had larger atrial volume indices (P = 0.002) and tended to have higher LV muscle mass indices (P = 0.07). Multiple regression analysis identified the total number of bicycle km as an independent factor for LV muscle mass. For left atrial size, heart rate at rest, age, years since the last bicycle race and the current hours of endurance training were identified as independent predictors. Long axis function of both ventricles (systolic velocities of mitral and tricuspid annulus) was decreased in PC (P

Patient radiation dose during percutaneous interventional closure of interatrial communications.

OBJECTIVE: To determine fluoroscopy time (FT) and radiation dose (RD) applied in percutaneous closure of interatrial septal communications (IAC). BACKGROUND: Percutaneous closure of IAC, namely patent foramen ovale (PFO) and atrial septal defect (ASD) is increasingly performed. In this often young population in full reproductive age, radiation dosage should be an important issue, yet consistent data on applied radiation dose have not been available to date. METHODS: A single center observational cohort study in 50 consecutive patients undergoing closure of a PFO or ASD. RD and FT as recorded by the cardiac catheter laboratory were determined to be the main outcome measures. Secondary outcome measures were determined to be major adverse events. RESULTS: FT averaged 6.3 (+/-4, 1.4-21.1) min, whereas RD measured as dose area product averaged 325.5 (+/-271.1; 11.6-1103.4) dGray x cm(2). The latter is equivalent to an effective dose of 6.5 milliSievert (0.24-22 mSv). CONCLUSION: Whereas closure of IAC can be associated with a low radiation exposure of 0.24 mSv, sometimes appreciably higher doses are applied, mandating more careful consideration of radiation safety issues in this patient population, especially the subset younger than 45 years. Analogous to data and recommendations published for radiation dose in coronary angiography, there is a need for binding reference values which would serve as guidelines for closure of IAC.

Fecal incontinence among morbid obese women seeking for weight loss surgery: an underappreciated association with adverse impact on quality of life.

PURPOSE: Morbid obesity is associated with urinary incontinence (UI). The study purpose was to determine the prevalence of fecal incontinence (FI), its associated risk factors, and its impact on quality of life (QOL) in morbidly obese women. MATERIALS AND METHODS: A questionnaire-based study on morbidly obese women [body mass index (BMI)>or=35 m/kg2], attending a bariatric surgery seminar, was conducted. Data included demographics, past medical, surgical and obstetric history, and obesity-related co-morbidities. Patients who reported of FI, completed the Cleveland Clinic Foundation Fecal Incontinence scale (CCF-FI) and the Fecal Incontinence Quality of Life scale (FIQL). RESULTS: Participants included 256 women [median age 45 years (19-70)] and mean BMI of 49.3+/-9.4 m/kg2. FI was reported in 63%. History of obstetric injury (OR: 2.4, 95% CI: 1.33-4.3; p<0.001) and UI (OR: 1.2, 95% CI: 1.1-1.4; p<0.001) were significantly associated with FI. There was no association with age, BMI, parity, and presence of diabetes or hypertension. Median CCF-FI score was 7 (1-20); 34.5% scored>or=10. Incontinence for gas was the most frequent type (87%) of FI, followed by incontinence for liquids (80%), which also had the highest impact on QOL (p<0.01). Mean FIQL scores were >3 for all four domains studied. CCF-FI scores were significantly correlated with FIQL scores in all domains (p=0.02). COMMENT: The prevalence of FI among morbidly obese women may be much higher than the rates reported in the general population. FI has adverse effects on QOL. Its correlation with UI suggests that morbid obesity may pose a risk of global pelvic floor dysfunction.

Sinus node disease and arrhythmias in the long-term follow-up of former professional cyclists.

AIMS: Significant brady- and tachyarrhythmias may occur in active endurance athletes. It is controversial whether these arrhythmias do persist after cessation of competitive endurance training. METHODS AND RESULTS: Among all 134 former Swiss professional cyclists [hereafter, former athletes (FAs)] participating at least once in the professional bicycle race Tour de Suisse in 1955-1975, 62 (46%) were recruited for the study. The control group consisted of 62 male golfers matched for age, weight, hypertension, and cardiac medication. All participants were screened with history, clinical and echocardiographic examination, ECG, and 24 h ECG. The time for the last bicycle race of FAs was 38 +/- 6 years. The mean age at examination was 66 +/- 6 years in controls and 66 +/- 7 years in FAs (P = 0.47). The percentage of study participants with >4 h current cardiovascular training per week was identical. QRS duration (102 +/- 20 vs. 95 +/- 13 ms, P = 0.03) and corrected QTc interval (416 +/- 27 vs. 404 +/- 18, P = 0.004) were longer in FAs. There was no significant difference in the number of isolated atrial or ventricular premature complexes, or supraventricular tachycardias in the 24 h ECG; however, ventricular tachycardias tended to occur more often in FAs than in controls (15 vs. 3%, P = 0.05). The average heart rate was lower in FAs (66 +/- 9 vs. 70 +/- 8 b.p.m.) (P = 0.004). Paroxysmal or persistent atrial fibrillation or flutter was reported more often in FAs (P = 0.028). Sinus node disease (SND), defined as bradycardia of <40 b.p.m. (10 vs. 2%), atrial flutter (6 vs. 0%), pacemaker for bradyarrhythmias (3 vs. 0%), and/or maximal RR interval of >2.5 s (6 vs. 0%), was more common in FA (16%) than in controls (2%, P = 0.006). Observed survival of all FAs was not different from the expected. CONCLUSIONS: Among FAs, SND occurred significantly more often compared with age-matched controls, and there is trend towards more frequent ventricular tachycardias. Further studies have to evaluate prevention of arrhythmias with extreme endurance training, the necessity of regular follow-up of heart rhythm, and management of arrhythmias in former competitive endurance athletes.

Pseudoaneurysm of the inferior gluteal artery: an unusual complication after abdominoperineal resection for rectal cancer. Report of a case.

We report an unusual case of profuse, sporadic hemorrhage from a chronically infected perineal wound after an abdominoperineal resection. Surgical exploration and angiography on two occasions failed to identify the source of bleeding. A pseudoaneurysm of the internal iliac artery was eventually identified with a provocative angiogram using tissue plasminogen activator. This aneurysm was successfully treated with embolization with coils.

Morbid obesity adversely impacts pelvic floor function in females seeking attention for weight loss surgery.

PURPOSE: This study was designed to determine the impact of excess body mass on the prevalence of pelvic floor disorders in morbidly obese females. METHODS: A total of 358 morbidly obese females (body mass index (BMI) >or= 35 kg/m(2)) completed two validated, condition-specific, quality of life questionnaires of pelvic floor dysfunction, which assessed stress/impact in three main domains of pelvic floor disorders: pelvic organ prolapse, colorectal-anal, and urogenital incontinence. Prevalence and severity scores in the study population were compared with data from 37 age-matched nonobese controls (BMI 35 kg/m(2) did not show increased adverse impacts on pelvic floor disorders symptoms. CONCLUSION: More than 90 percent of morbidly obese females experience some degree of pelvic floor disorders, and 50 percent of these females report that symptoms adversely impact quality of life. In morbidly obese females, obesity is as important as obstetric history in predicting pelvic floor dysfunction.
