Long-term functional outcome of colonic resections: how much does faecal impairment influence quality of life?

AIM: Older data suggest that colonic resection has a negative impact on continence and quality of life. The aim of this study was to evaluate the functional outcome of colonic resections for colonic cancer and diverticulitis and its influence on quality of life. METHODS: Patients who underwent colonic resection between 2005 and 2013 were identified from a prospective database. A survey with two questionnaires [Faecal Incontinence Quality of Life (FIQL) scale, Short Form 12 (SF-12)] and additional questions concerning bowel function was sent to all patients. RESULTS: Colonic resection was performed in 362 patients in the study period; 297 patients returned the questionnaires (response rate 82.0%). Faecal urgency or incontinence more than once a month was present in 15% of patients and 25% of patients reported that bowel symptoms limited their quality of life. The mean total FIQL score for all patients was 3.58. The SF-12 score was comparable to a reference population without prior colonic resection. Patients after right-sided resections had liquid stool more often than others (45.3% vs 38.7%, P = 0.011). No differences in bowel function and quality of life were detected between resections for colonic cancer and diverticulitis. CONCLUSION: Most patients experience no limitation in bowel function after segmental colectomy. Those with limitations in bowel function still seem to cope well, as the quality of life is not severely affected. Nevertheless, most patients with lower functional scores also had lower quality of life scores. Whether surgery is a relevant factor has to be questioned, as the prevalence of faecal incontinence in a comparable population without prior surgery is almost identical.

Vitamin D levels and associated factors: a population-based study in Switzerland.

QUESTIONS UNDER STUDY: To update the prevalence of vitamin D insufficiency and to identify factors associated with vitamin D status in the Swiss adult population. METHODS: Data from the 2010-2011 Swiss Study on Salt intake, a population-based study in the Swiss population, was used. Vitamin D concentration in serum was measured by liquid chromatography- tandem mass spectrometry. Major factors that influence vitamin D levels were taken into account. Survey statistical procedures were used to estimate means and prevalences of vitamin D levels and status. Monthly-specific tertiles of vitamin D and ordinal logistic regression were used to determine the associations of covariates of interest with vitamin D status. RESULTS: The prevalences of vitamin D insufficiency (serum 25-hydroxyvitamin D: 20-29.9 ng/ml) and deficiency (<20 ng/ml) were the highest in the January-March period; 26.4% (95%CI: 21.6-31.7) and 61.6% (95%CI: 56.0-67.0), respectively. In the same period, more than 9 of ten men were vitamin D insufficient or deficient. Each unit increase of Body Mass Index was associated with an 8% decreased likelihood of being in a higher vitamin D tertiles. Oral contraceptive, altitude, urinary excretion of calcium, use of vitamin D supplement or treatment, high wine consumption, physical activity were associated with vitamin D tertiles. Compared to the French-speaking region, the Italian-speaking region was independently associated with a higher likelihood of being in higher vitamin D tertiles (OR: 1.66, 95%CI: 1.14-2.43). CONCLUSIONS: Low levels of vitamin D are common among Swiss adults, in particular during winter months and outside the Italian-speaking region.

[Hypertension in solid organ transplants]. / L'hypertension chez les transplantés d'organes.

Hypertension is highly prevalent in transplantation and affects all type of organs. With the introduction of calcineurin inhibitors as immunosuppressive drugs, acute allograft rejection episodes have been significantly reduced and hence patient and allograft survival rates have dramatically improved. However, cardiovascular complications have become an important cause of morbidity and mortality. Treating cardiovascular risk factors such as diabetes, dyslipidemia and hypertension seems obvious, however in this population, there is little evidence for specific blood pressure targets, or for the best strategy to achieve blood pressure control. The aim of this article is to review the epidemiology and physiopathology of hypertension in transplant recipients as well as its clinical management.

Clinical research opportunities: what you need to know for your practice.

Cardiologists and cardiovascular practitioners are facing significant reimbursement constraints. In this setting, increasing numbers of practitioners are looking to participate in clinical research as a new source of revenue. An aging population and consolidation among pharmaceutical companies, medical device companies, and contract research organizations are placing great emphasis on speed of new products to market. Opportunities exist for well-positioned and knowledgeable clinical investigators to enhance their practices, increase their professional knowledge, and expand their network of scientific colleagues. This article provides an overview of the drug and pharmaceutical industry referable to clinical investigation, the tools necessary to become a valued, principal investigator and an outline of challenges and opportunities for clinicians wishing to engage and enhance their clinical research activities.
