Background. Surgical stress during major surgery may be related to adverse clinical outcomes and early quantification of stress response would be useful to allow prompt interventions. The aim of this study was to evaluate the acute phase protein albumin in the context of the postoperative stress response. Methods. This prospective pilot study included 70 patients undergoing frequent abdominal procedures of different magnitude. Albumin (Alb) and C-reactive protein (CRP) levels were measured once daily starting the day before surgery until postoperative day (POD) 5. Maximal Alb decrease (Alb Δ min) was correlated with clinical parameters of surgical stress, postoperative complications, and length of stay. Results. Albumin values dropped immediately after surgery by about 10 g/L (42.2±4.5 g/L preoperatively versus 33.8±5.3 g/L at day 1, P

Fat redistribution, increased inflammation and insulin resistance are prevalent in non-diabetic subjects treated with maintenance dialysis. The aim of this study was to test whether pioglitazone, a powerful insulin sensitizer, alters body fat distribution and adipokine secretion in these subjects and whether it is associated with improved insulin sensitivity.This was a double blind cross-over study with 16 weeks of pioglitazone 45 mg vs placebo involving 12 subjects.At the end of each phase, body composition (anthropometric measurements, dual energy X-ray absorptometry (DEXA), abdominal CT), hepatic and muscle insulin sensitivity (2-step hyperinsulinemic euglycemic clamp with 2H2-glucose) were measured and fasting blood adipokines and cardiometabolic risk markers were monitored.Four months treatment with pioglitazone had no effect on total body weight or total fat but decreased the visceral/sub-cutaneous adipose tissue ratio by 16% and decreased the leptin/adiponectin (L/A) ratio from 3.63 × 10(-3) to 0.76 × 10(-3). This was associated with a 20% increase in hepatic insulin sensitivity without changes in muscle insulin sensitivity, a 12% increase in HDL cholesterol and a 50% decrease in CRP.Pioglitazone significantly changes the visceral-subcutaneous fat distribution and plasma L/A ratio in non diabetic subjects on maintenance dialysis. This was associated with improved hepatic insulin sensitivity and a reduction of cardio-metabolic risk markers. Whether these effects may improve the outcome of non diabetic end-stage renal disease subjects on maintenance dialysis still needs further evaluation.ClinicalTrial.gov NCT01253928.

Summary Background & aims Undernutrition is associated with increased hospital costs. Whether these increased costs are totally compensated by third payer systems has not been assessed. We aimed to assess the differences between actual and reimbursed hospital costs according to presence/absence of nutritional risk, defined by a Nutritional risk screening-2002 (NRS-2002) score ≥3. Methods Retrospective study. Administrative data for years 2013 and 2014 of the department of internal medicine of the Lausanne university hospital. The data included total and specific costs (i.e. clinical biology, treatments, pathology). Reimbursed costs were based on the Swiss Diagnosis Related Group (DRG) system. Results 2200 admissions with NRS-2002 data were included (mean age 76 years, 53.9% women), 1398 (63.6%) of which were considered nutritionally ‘at-risk’. After multivariate adjustment, patients nutritionally ‘at-risk’ had higher costs (multivariate-adjusted difference ± standard error: 34,206 ± 1246 vs. 22,214 ± 1666 CHF, p < 0.001) and higher reimbursements (26,376 ± 1105 vs. 17,783 ± 1477 CHF, p < 0.001). Still, the latter failed to cover the costs, leading to a deficit between costs and reimbursements of 7831 ± 660 CHF in patients ‘at-risk’ vs. 4431 ± 881 in patients ‘not at-risk’ (p < 0.003). Being nutritionally ‘at-risk’ also led to a lower likelihood of complete coverage of costs: multivariate-adjusted odds ratio and 95% confidence interval 0.77 (0.62–0.97). Patients ‘at-risk’ had lower percentage of total costs in medical interventions, food, imaging and “other”, but the absolute differences were less than 2%. Conclusion Hospital costs of patients nutritionally ‘at-risk’ are less well reimbursed than of patients ‘not at-risk’. Better reporting of undernutrition in medical records and better reimbursement of undernourished patients is needed. [ABSTRACT FROM AUTHOR]

Summary Background The Nutritional Risk Score (NRS) is a validated tool to identify patients who should benefit of nutritional interventions. Nutritional screening however has not yet been widely adopted by surgeons. Furthermore, the question about reliability of nutritional assessment performed by surgeons is still unanswered. Methods Data was obtained from a recent randomised trial including 146 patients with an NRS ≥3 as assessed by the surgeons. Additional detailed nutritional assessment was performed for all patients by nutritional specialists and entered prospectively in a dedicated database. In this retrospective, surgeons' scoring of NRS and its components was compared to the assessment by nutritionists (considered as gold standard). Results Prospective NRS scores by surgeons and nutritionists were available for 141 patients (97%). Surgeons calculated a NRS of 7, 6, 5, 4 and 3 in 2, 8, 38, 21 and 72 patients respectively. Nutritionists calculated a NRS of 6, 5, 4, 3 and 2 in 8, 26, 47, 57, 3 patients, respectively. Surgeons' assessment was entirely correct in 56 patients (40%), while at least the final score was consistent in 63 patients (45%). Surgeons overrated the NRS in 21% of patients and underestimated the score in 29%. Evaluation of the nutritional status showed most of the discrepancies (54%). Conclusion Surgeon's assessment of nutritional status is modest at best. Close collaboration with nutritional specialists should be recommended in order to avoid misdiagnosis and under-treatment of patients at nutritional risk. [ABSTRACT FROM AUTHOR]

Nutrition is central in pediatric care : essential for growth and development, it plays also a role in the prevention of many diseases.Even if breastfeeding is highly recommended, its implementation may be difficult in particular for premature and ill newborns. The creation of a specific unit for breastfeeding support in neonatology allows to help mothers willing to nurse and to improve the rate of breastfeeding for these vulnerable infants.Eating disorders represent an important challenge for patient care. Early detection and rapid management of anorexia is essential for the prognosis. This article describes the challenges and the practical process underlying the development of a practical guideline to manage children and adolescents hospitalized for anorexia., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Background. Surgical stress during major surgery may be related to adverse clinical outcomes and early quantification of stress response would be useful to allow prompt interventions. The aim of this study was to evaluate the acute phase protein albumin in the context of the postoperative stress response. Methods. This prospective pilot study included 70 patients undergoing frequent abdominal procedures of different magnitude. Albumin (Alb) and C-reactive protein (CRP) levels were measured once daily starting the day before surgery until postoperative day (POD) 5. Maximal Alb decrease (Alb Δ min) was correlated with clinical parameters of surgical stress, postoperative complications, and length of stay. Results. Albumin values dropped immediately after surgery by about 10 g/L (42.2 ± 4.5 g/L preoperatively versus 33.8 ± 5.3 g/L at day 1, P < 0.001). Alb Δ min was correlated with operation length (Pearson ρ = 0.470, P < 0.001), estimated blood loss (ρ = 0.605, P < 0.001), and maximal CRP values (ρ = 0.391, P = 0.002). Alb Δ min levels were significantly higher in patients having complications (10.0 ± 5.4 versus 6.1 ± 5.2, P = 0.005) and a longer hospital stay (ρ = 0.285, P < 0.020). Conclusion. Early postoperative albumin drop appeared to reflect the magnitude of surgical trauma and was correlated with adverse clinical outcomes. Its promising role as early marker for stress response deserves further prospective evaluation.

Background/aims: The aim of the current study was to assess the postoperative evolution of nutritional status and to relate it with postoperative outcomes., Methods: Demographic, surgical and nutritional parameters were assessed 10 days preoperatively (d-10) and 30 days postoperatively (d30) in 146 patients. Risk factors responsible for perioperative (>5% between d-10 and d30) weight loss were identified. Overall, severe (Clavien 3-5) and infectious complications were compared in patients with and without perioperative weight loss (>5%)., Results: Nutritional status worsened beyond the postoperative period as reflected by decreasing weight (67 ± 13 kg at d-10 vs. 63 ± 13 kg at d30, p < 0.001), body mass index (23.4 ± 4 vs. 22.2 ± 4 kg/m2, p < 0.001) and mid upper-arm muscle circumference (MAMC, 241 ± 32 vs. 232 ± 30 mm, p < 0.001). Fifty-two patients (46%) lost >5% of their body weight between d-10 and d30. Patients who presented overall (63 vs. 36%, p = 0.004) and major (27 vs. 10%, p = 0.016) postoperative complications were at significantly higher risk to deteriorate postoperative nutritional status. Multivariate analysis identified low preoperative lean body mass (OR 3.2; 95% CI 1.2-8.9, p = 0.023) and low preoperative MAMC (OR 2.5; 95% CI 0.9-6.8, p = 0.066) as independent risk factors for perioperative weight loss., Conclusions: These data suggest continuing nutritional follow-up after the index hospitalization., (© 2016 S.

Screening for undernutrition among hospitalized children requires a systematic assessment of dietary intake. The development of a new tool for quick and playful assessment of dietary intake, called "Fleur" ("Flower"), at the Hôpital de l'Enfance in Lausanne allows to identify children at risk of undernutrition and to adapt their nutrition to their specific needs.

Acquired pressure ulcer is associated with significant human, economic and functional consequences. Its prevalence varies between 3 and 23% in a community hospital and between 7 and 54% in an elderly home residency. Pressure ulcer healing is a complex process which involves numerous cellular and molecular mechanisms. An altered nutritional status is a contributing factor in the development of pressure ulcers and the delay in pressure ulcer healing. The key to management of undernutrition is screening and early intervention. According to the gravity of undernutrition, various degrees of intervention will be required. Systematic oral supplementation with various nutrients may provide benefit in the prevention of pressure ulcers, but further studies have to be completed in human subjects prior to being recommended for the treatment of pressure ulcers.

About 1/5 of patients are undernourished in Swiss hospitals. Despite of a high morbidity and mortality associated with this pathology, nearly 1/3 of them do not receive an appropriate nutritional support which can be even indicated at an obese patient. This paper approaches the key points of early nutritional care. NRS-2002 is presented like a simple tool able to identify patients nutritionally at-risk who are likely to benefit from nutritional support. Moreover, the major role of a diet adapted to the specific needs of the patient points out the need for an institutional policy coordinated around diet-nutrition.

Docosahexaenoic acid [22:6(n-3)] is enriched in brain membrane phospholipids and essential for brain function. Neurogenesis during embryonic and fetal development requires synthesis of large amounts of membrane phospholipid. We determined whether dietary (n-3) fatty acid deficiency during gestation alters neurogenesis in the embryonic rat brain. Female rats were fed diets with 1.3% energy [(n-3) control] or 0.02% energy [(n-3) deficient], from alpha-linolenic acid [18:3(n-3)], beginning 2 wk before gestation. Morphometric analyses were performed on embryonic day 19 to measure the mean thickness of the neuroepithelial proliferative zones corresponding to the cerebral cortex (ventricular and subventricular zones) and dentate gyrus (primary dentate neuroepithelium), and the thickness of the cortical plate and sectional area of the dentate gyrus. Phospholipids and fatty acids were determined by HPLC and GLC. Docosahexaenoic acid was 55-65% lower and (n-6) docosapentaenoic acid [22:5(n-6)] was 150-225% higher in brain phospholipids at embryonic day 19 in the (n-3) deficient (n = 6 litters) than in the control (n = 5 litters) group. The mean thickness of the cortical plate and mean sectional area of the primordial dentate gyrus were 26 and 48% lower, respectively, and the mean thicknesses of the cortical ventricular zone and the primary dentate neuroepithelium were 110 and 70% higher, respectively, in the (n-3) deficient than in the control embryonic day 19 embryos. These studies demonstrate that (n-3) fatty acid deficiency alters neurogenesis in the embryonic rat brain, which could be explained by delay or inhibition of normal development.
