Urinary incontinence as a marker of higher mortality in patients receiving home care services.

OBJECTIVE: To evaluate urinary incontinence (UI) as a predictor of nursing home admission, hospitalization or death in patients receiving home care services. SUBJECTS AND METHODS: A total of 699 community-dwelling participants receiving home care services in Geneva were evaluated in Autumn 2004 using the Minimal Data Set-Home Care, a validated instrument that includes grading of UI. Data on death, hospitalization and nursing home admission were collected up until June 2007. The impact of UI on time-dependent outcomes was analysed using survival analysis and multivariate regression Cox models to adjust for age, gender, body mass index, cardiac failure, cognitive impairment, delirium, depression, disability, alcohol and tobacco use, self-rated health, faecal incontinence and number of medications. RESULTS: We found that UI was present in 193 participants (27.8%). After adjustment for confounding factors, UI was associated with a longer length of hospital stay: +36.7 days, (95% confidence interval [CI]: 1.2-72.3) and a higher mortality rate (hazard ratio [HR] 1.6; 95% CI: 1.1-2.6). The HR for death was 1.5 (95% CI: 0.9-2.5) for participants complaining of one episode of urinary leakage per week at most, 2.0 (95% CI: 1.2-3.5) for those presenting with two or more episodes per week and 4.2 (95% CI: 2.3-7.7; P for trend: <0.001) for daily UI compared with participants without UI. Institutionalization (HR 1.1; 95% CI: 0.6-2.2) and hospitalization rates (HR 1.0; 95% CI: 0.7-1.3) were not different between patients with or without UI. CONCLUSION: In a cohort of patients receiving home care services, UI was a strong predictor of length of hospital stay and mortality, increasing with UI severity.

Comparative sensitivities of functional MRI sequences in detection of local recurrence of prostate carcinoma after radical prostatectomy or external-beam radiotherapy.

OBJECTIVE: The aim of this retrospective study was to determine the respective accuracies of three types of functional MRI sequences-diffusion-weighted imaging (DWI), dynamic contrast-enhanced (DCE) MRI, and 3D (1)H-MR spectroscopy (MRS)-in the depiction of local prostate cancer recurrence after two different initial therapy options. MATERIALS AND METHODS: From a cohort of 83 patients with suspicion of local recurrence based on prostate-specific antigen (PSA) kinetics who were imaged on a 3-T MRI unit using an identical protocol including the three functional sequences with an endorectal coil, we selected 60 patients (group A, 28 patients who underwent radical prostatectomy; group B, 32 patients who underwent external-beam radiation) who had local recurrence ascertained on the basis of a transrectal ultrasound-guided biopsy results and a reduction in PSA level after salvage therapy. RESULTS: All patients presented with a local relapse. Sensitivity with T2-weighted MRI and 3D (1)H-MRS sequences was 57% and 53%, respectively, for group A and 71% and 78%, respectively, for group B. DCE-MRI alone showed a sensitivity of 100% and 96%, respectively, for groups A and B. DWI alone had a higher sensitivity for group B (96%) than for group A (71%). The combination of T2-weighted imaging plus DWI plus DCE-MRI provided a sensitivity as high as 100% in group B. CONCLUSION: The performance of functional imaging sequences for detecting recurrence is different after radical prostatectomy and external-beam radiotherapy. DCE-MRI is a valid and efficient tool to detect prostate cancer recurrence in radical prostatectomy as well as in external-beam radiotherapy. The combination of DCE-MRI and DWI is highly efficient after radiation therapy. Three-dimensional (1)H-MRS needs to be improved. Even though it is not accurate enough, T2-weighted imaging remains essential for the morphologic analysis of the area.

Reproducibility and gender-related differences of heart rate variability during all-day activity in young men and women.

BACKGROUND: Only few data are available on reproducibility over time in healthy young men and women and the corresponding gender-related changes of heart rate variability (HRV) measurements. METHODS: We studied temporal and spectral HRV indices obtained from 24-hour Holter recordings in 32 healthy volunteers (14 men and 18 women, mean age 29 +/- 3 years) during 2 days of their usual all-day activity. RESULTS: Time-domain measures and the spectral low-frequency (LF) and high-frequency (HF) components as well as the LF/HF ratio were comparable on both test days. Significantly higher values on test day 2 were observed only for the spectral very-low-frequency (VLF) component and for the resulting total power. Compared to men, women had higher day- and nighttime vagus-associated HRV indices, including root mean square of successive differences (RMSSD), pNN50 (NN50 count divided by the total number of all NN intervals), and HF power, and lower day- and nighttime VLF and LF power with lower LF/HF ratio and total power. CONCLUSIONS: Temporal indices and the LF and HF spectral HRV measures are reproducible over usual all-day activity in young healthy subjects. Young women have higher day-and nighttime vagal tone than men with similar age range.
