Prevalence of faecal incontinence among women with urinary incontinence

Four hundred and sixty-five women attending a urodynamic clinic were interviewed, and completed a detailed bowel questionnaire, about their urinary and bowel symptoms. All the women underwent video-cystourethrography with pressure and flow studies. The reported incidence of faecal incontinence was 15.3% (   n = 71  ) on direct questioning and 26% 0(  n = 121  ) on the postal questionnaire. Faecal incontinence was more common in women with a urodynamic diagnosis of detrusor instability (30'%1 (   n = 26  )) than among women diagnosed as having genuine stress incontinence (21% (   n = 38  )). Denervation and myogenic injuries sustained during childbirth have been suggested as a common cause for genuine stress and faecal incontinence, but there may be an alternative mechanism to explain why women with detrusor instability suffer from faecal incontinence.     

Reproducibility of Echocardiograph‐Derived Multilevel Left Ventricular Apical Twist Mechanics

Left ventricular (LV) twist mechanics are routinely assessed via echocardiography in clinical and research trials investigating the function of obliquely oriented myocardial fibers. However, echocardiograph‐derived measures of LV twist may be compromised by nonstandardized acquisition of the apical image. This study examined the reproducibility of echocardiograph‐derived parameters of apical twist mechanics at multiple levels of the apical myocardium. Two sets of 2D LV parasternal short‐axis images were obtained in 30 healthy subjects (24 men; 19–57 year) via echocardiography. Images were acquired immediately distal to the papillary muscles (apical image 1), immediately above the point of LV cavity obliteration at end systole (apical image 3), and midway between apical image 1 and apical image 3 (apical image 2). Repeat scans were performed within 1 hour, and twist mechanics (rotation and rotation rate) were calculated via frame‐by‐frame tracking of natural acoustic echocardiographic markers (speckle tracking). The magnitude of apical rotation increased progressively toward the apex (apical image 1: 4.2 ± 2.1°, apical image 2: 7.2 ± 3.9°, apical image 3: 11.8 ± 4.6°). apical images 1, 2, and 3 each had moderate to good correlations between repeat scans (ICC: 0.531–0.856). When apical images 1, 2, and 3 were averaged, rotation was 7.7 ± 2.7° and between‐scan correlation was excellent (ICC: 0.910). Similar results were observed for systolic and diastolic rotation rates. Averaging multiple standardized apical images, tending progressively toward the apex, generated the most reproducible rotation indices and may be optimal for the assessment of LV twist mechanics across therapeutic, interventional, and research studies; however, care should be taken given the influence of acquisition level on the magnitude of apical rotation.     

Connecting food,well-being and environmental sustainability: towards an integrative public health nutrition

Modern society has no shortage of human nutrition science, nor interventions designed to improve the way we eat. Yet nutrition science, and the models, approaches and interventions derived from this, is apparently delivering diminishing returns in terms of population weight gain, unhealthy eating patterns and the obesity ‘epidemic’. We draw on a range of literature(s) to argue that public health nutritionists in affluent societies face an ingenuity gap – a series of complex and inter-connected challenges which are neither fully recognised nor easily amenable to resolution through conventional thinking and practice. Four such challenges are: nutritionism; economism; consumerism and individualism. We use an integrative framework to explain their significance for public health nutrition, where they exert a combined and compounding influence. In addition to these problems, insights from other disciplines show that ‘modern’ society and some of its key characteristics are linked to increasing environmental threats. The latter undermine food security and the sustainability of society itself, and possess global impact. For public health nutrition to be situated in and responsive to this broader context, the discipline will need a better understanding of the relationship between modern society, food choice and environmental sustainability. As ‘healthy eating’ may not be an achievable goal within the present social, economic and cultural system, public health nutrition has a unique and vital role to play in shaping change for the future.
