Objective To determine whether planned caesarean section (CS) for a second delivery protects against anal incontinence in women with obstetric anal sphincter lesions. Design Randomised trial. Setting Six maternity units in the Paris area. Sample Women at high risk of sphincter lesions (first delivery with third-degree laceration and/or forceps) but no symptomatic anal incontinence. Methods Endoanal ultrasound was performed in the third trimester of the second pregnancy. Women with sphincter lesions were randomised to planned CS or vaginal delivery (VD). Main outcome measures Anal incontinence at 6 months postpartum. Secondary outcomes were urinary incontinence, sexual morbidity, maternal and neonatal morbidities and worsening of external sphincter lesions. Results Anal sphincter lesions were detected by ultrasound in 264/434 women enrolled (60.8%); 112 were randomised to planned VD and 110 to planned CS. At 6-8 weeks after delivery, there was no significant difference in anal continence between the two groups. At 6 months after delivery, median Vaizey scores of anal incontinence were 1 (interquartile range 0-4) in the CS group and 1 (interquartile range 0-3) in the VD group (P = 0.34). There were no significant differences for urinary continence, sexual functions or for other maternal and neonatal morbidities. Conclusions In women with asymptomatic obstetric anal sphincter lesions diagnosed by ultrasound, planning a CS had no significant impact on anal continence 6 months after the second delivery. These results do not support advising systematic CS for this indication. Tweetable abstract Caesarean section for the second delivery did not protect against anal incontinence in women with asymptomatic obstetric anal sphincter lesions.

Our objective was to find a mean flow velocity (MFV) cut-off point to differentiate between normal and cognitive impaired patients using Clinical Dementia Rating (CDR) as a comparison method. To evaluate MFV (in cm/s) and pulsatility index (PI) from the left middle cerebral artery (MCA) and basilar artery using transcranial Doppler in a pilot study from an outpatient cognition unit and compare with cognitively normal older adults (at the age of sixty or older) from the Geriatric Ambulatory of Fluminense Federal University. We hypothesized that there is a MFV and PI cut-off point to potentially distinguish between normal and impaired cognition. Sixty-one patients with cognitive decline, including 18 with amnestic mild cognitive impairment (aMCI), 31 with probable Alzheimer disease (AD), 12 with vascular dementia (VD), and 10 cognitively normal older adults were included in the study. Patients with dementia (both AD and VD, p < 0.01) and aMCI (p < 0.05) had lower MFV than the control group in the MCA (32.2 cm/s, 31.9 cm/s, and 36.6 cm/s, respectively) and dementia patients had higher PI compared to control (AD and VD, both p < 0.05). Basilar MFV showed to be no difference between the patients and the control group. A cut off value of 39.1 cm/s was found in a ROC curve (area under de curve value 0.85, 95% CI 0.75-0.95) for mean MCA MFV to be predictive of cognitive impairment (CDR >= 0.5). In this study, the values of MCA MFV below 39.1 cm/s were predictive of cognitive impairment according to CDR. TCD is an inexpensive method that could be used in a clinical scenario to help differentiate normal cognition from cognitive decline. Multicentric and longitudinal studies should be done to validate that.
