- Background & aims: The aim of the Enhanced Recovery After Surgery (ERAS) pathway is to attenuate the stress response to surgery and enable rapid recovery. The objective of this meta-analysis was to study the differences in outcomes in patients undergoing major elective open colorectal surgery within an ERAS pathway and those treated with conventional perioperative care.Methods: Medline, Embase and Cochrane database searches were performed for relevant studies published between January 1966 and November 2009. All randomized controlled trials comparing ERAS with conventional perioperative care were selected. The outcome measures studied were length of hospital stay, complication rates, readmission rates and mortality.Results: Six randomized controlled trials with 452 patients were included. The number of individual ERAS elements used ranged from 4 to 12, with a mean of 9. The length of hospital stay [weighted mean difference (95% confidence interval): -2.55 (-3.24, -1.85)] and complication rates [relative risk (95% confidence interval): 0.53 (0.44, 0.64)] were significantly reduced in the enhanced recovery group. There was no statistically significant difference in readmission and mortality rates.Conclusion: ERAS pathways appear to reduce the length of stay and complication rates after major elective open colorectal surgery without compromising patient safety.

In: Clinical Nutrition. - : Churchill Livingstone. - 0261-5614 .- 1532-1983. ; 35:2, s. 408-413

Journal article (peer-reviewed)abstract
- Background: Patients receiving a carbohydrate drink (CHO) before major abdominal surgery display improved insulin sensitivity postoperatively and increased proteolysis of IGFBP-3 (IGFBP-3-PA) compared to patients undergoing similar surgery after overnight fasting. Aims: We hypothesized that serum IGFBP-3-PA increases bioavailability of circulating IGF-I and preserves insulin sensitivity in patients given CHO. Design: Matched control study. Methods: At Karolinska University Hospital, patients given CHO before major elective abdominal surgery (CHO,n = 8) were compared to patients undergoing similar surgical procedures after overnight fasting (FAST,n = 10). Results from two different techniques for determination of free-dissociable IGF-I (fdIGF-I) were compared with changes in IGFBP-3-PA and insulin sensitivity. Results: Postoperatively, CHO displayed 18% improvement in insulin sensitivity (hyperinsulinemic clamp) and increased IGFBP-3-PA vs. FAST. As determined by IRMA, fdIGF-I increased by 48 +/- 25% in CHO while fdIGF-I decreased by 13 +/- 18% in FAST (p < 0.01 vs. CHO, when corrected for duration of surgery). However, fdIGF-I determined by ultra-filtration decreased similarly in both groups (-22 +/- 8% vs. -25 +/- 8%, p = 0.8) and IGFBP-1 increased similarly in both groups. Patients with less insulin resistance after surgery demonstrated larger increases in fdIGF-I by IRMA (r = 0.58, p < 0.05). Fifty-three % of the variability of the changes in fdIGF-I by IRMA could be explained by changes in IGFBP-3-PA and total IGF-I levels (p < 0.05), while IGFBP-1 did not contribute significantly. Conclusion: During conditions when serum IGF-I bioavailability is regulated by IGFBP-3 proteolysis, measurements of fdIGF-I by IRMA is of physiological relevance as it correlates with the associated changes in insulin sensitivity.

Carbohydrates and insulin resistance in clinical nutrition : Recommendations from the ESPEN expert group.
- 2017

In: Clinical Nutrition. - : Elsevier BV. - 0261-5614 .- 1532-1983. ; 36:2, s. 355-363

Journal article (peer-reviewed)abstract
- Growing evidence underscores the important role of glycemic control in health and recovery from illness. Carbohydrate ingestion in the diet or administration in nutritional support is mandatory, but carbohydrate intake can adversely affect major body organs and tissues if resulting plasma glucose becomes too high, too low, or highly variable. Plasma glucose control is especially important for patients with conditions such as diabetes or metabolic stress resulting from critical illness or surgery. These patients are particularly in need of glycemic management to help lessen glycemic variability and its negative health consequences when nutritional support is administered. Here we report on recent findings and emerging trends in the field based on an ESPEN workshop held in Venice, Italy, 8-9 November 2015. Evidence was discussed on pathophysiology, clinical impact, and nutritional recommendations for carbohydrate utilization and management in nutritional support. The main conclusions were: a) excess glucose and fructose availability may exacerbate metabolic complications in skeletal muscle, adipose tissue, and liver and can result in negative clinical impact; b) low-glycemic index and high-fiber diets, including specialty products for nutritional support, may provide metabolic and clinical benefits in individuals with obesity, insulin resistance, and diabetes; c) in acute conditions such as surgery and critical illness, insulin resistance and elevated circulating glucose levels have a negative impact on patient outcomes and should be prevented through nutritional and/or pharmacological intervention. In such acute settings, efforts should be implemented towards defining optimal plasma glucose targets, avoiding excessive plasma glucose variability, and optimizing glucose control relative to nutritional support.

The effect of glucose control in liver surgery on glucose kinetics and insulin resistance
- 2021

In: Clinical Nutrition. - : Churchill Livingstone. - 0261-5614 .- 1532-1983. ; 40:7, s. 4526-4534

Journal article (peer-reviewed)abstract
- BACKGROUND & AIMS: Clinical outcome is negatively correlated to postoperative insulin resistance and hyperglycemia. The magnitude of insulin resistance can be modulated by glucose control, preoperative nutrition, adequate pain management and minimal invasive surgery. Effects of glucose control on perioperative glucose kinetics in liver surgery is less studied.METHODS: 18 patients scheduled for open hepatectomy were studied per protocol in this prospective, randomized study. In the treatment group (n = 9), insulin was administered intravenously to keep arterial blood glucose between 6 and 8 mmol/l during surgery. The control group (n = 9) received insulin if blood glucose >11.5 mmol/l. Insulin sensitivity was measured by an insulin clamp on the day before surgery and immediately postoperatively. Glucose kinetics were assessed during the clamp and surgery.RESULTS: Mean intraoperative glucose was 7.0 mM (SD 0.7) vs 9.1 mM (SD 1.9) in the insulin and control group respectively (p < 0.001; ANOVA). Insulin sensitivity decreased in both groups but significantly (p = 0.03, ANOVA) more in the control group (M value: 4.6 (4.4-6.8) to 2.1 (1.2-2.6) and 4.6 (4.1-5.0) to 0.6 (0.1-1.8) mg/kg/min in the treatment and control group respectively). Endogenous glucose production (EGP) increased and glucose disposal (WGD) decreased significantly between the pre- and post-operative clamps in both groups, with no significant difference between the groups. Intraoperative kinetics demonstrated that glucose control decreased EGP (p = 0.02) while WGD remained unchanged (p = 0.67).CONCLUSION: Glucose control reduces postoperative insulin resistance in liver surgery. EGP increases and WGD is diminished immediately postoperatively. Insulin seems to modulate both reactions, but mostly the WGD is affected. Intraoperative EGP decreased while WGD remained unaltered.REGISTRATION NUMBER OF CLINICAL TRIAL: ANZCTR 12614000278639.

The international declaration on the human right to nutritional care : A global commitment to recognize nutritional care as a human right
- 2023

In: Clinical Nutrition. - : Churchill Livingstone. - 0261-5614 .- 1532-1983. ; 42:6, s. 909-918
-
Journal article (other academic/artistic)abstract
- Access to nutritional care is frequently limited or denied to patients with disease-related malnutrition (DRM), to those with the inability to adequately feed themselves or to maintain their optimal healthy nutritional status which goes against the fundamental human right to food and health care. That is why the International Working Group for Patient's Right to nutritional care is committed to promote a human rights based approach (HRBA) in the field of clinical nutrition. Our group proposed to unite efforts by launching a global call to action against disease-related malnutrition through The International Declaration on the Human Right to Nutritional Care signed in the city of Vienna during the 44th ESPEN congress on September 5th 2022. The Vienna Declaration is a non-legally binding document that sets a shared vision and five principles for implementation of actions that would promote the access to nutritional care. Implementation programs of the Vienna Declaration should be promoted, based on international normative frameworks as The United Nations (UN) 2030 Agenda for Sustainable Development, the Rome Declaration of the Second International Conference on Nutrition and the Working Plan of the Decade of Action on Nutrition 2016-2025. In this paper, we present the general background of the Vienna Declaration, we set out an international normative framework for implementation programs, and shed a light on the progress made by some clinical nutrition societies. Through the Vienna Declaration, the global clinical nutrition network is highly motivated to appeal to public authorities, international governmental and non-governmental organizations and other scientific healthcare societies on the importance of optimal nutritional care for all patients.

- 2015
-
In: Annals of Surgery. - : Lippincott Williams & Wilkins. - 0003-4932 .- 1528-1140. ; 261:6, s. 1153-1159

Journal article (peer-reviewed)abstract
- Background: The ERAS (enhanced recovery after surgery) care has been shown in randomized clinical trials to improve outcome after colorectal surgery compared to traditional care. The impact of different levels of compliance and specific elements, particularly out with a trial setting, is poorly understood.Objective: This study evaluated the individual impact of specific patient factors and perioperative enhanced recovery protocol compliance on postoperative outcome after elective primary colorectal cancer resection.Methods: The international, multicenter ERAS registry data, collected between November 2008 and March 2013, was reviewed. Patient demographics, disease characteristics, and perioperative ERAS protocol compliance were assessed. Linear regression was undertaken for primary admission duration and logistic regression for the development of any postoperative complication.Findings: A total of 1509 colonic and 843 rectal resections were undertaken in 13 centers from 6 countries. Median length of stay for colorectal resections was 6 days, with readmissions in 216 (9.2%), complications in 948 (40%), and reoperation in 167 (7.1%) of 2352 patients. Laparoscopic surgery was associated with reduced complications [odds ratio (OR) = 0.68; P < 0.001] and length of stay (OR = 0.83, P < 0.001). Increasing ERAS compliance was correlated with fewer complications (OR = 0.69, P < 0.001) and shorter primary hospital admission (OR = 0.88, P < 0.001). Shorter hospital stay was associated with preoperative carbohydrate and fluid loading (OR = 0.89, P = 0.001), and totally intravenous anesthesia (OR= 0.86, P < 0.001); longer stay was associated with intraoperative epidural analgesia (OR = 1.07, P = 0.019). Reduced postoperative complications were associated with restrictive perioperative intravenous fluids (OR = 0.35, P < 0.001).Conclusions: This analysis has demonstrated that in a large, international cohort of patients, increasing compliance with an ERAS program and the use of laparoscopic surgery independently improve outcome.

Derangements in mitochondrial metabolism in intercostal and leg muscle of critically ill patients with sepsis-induced multiple organ failure
- 2006
-
In: American Journal of Physiology. Endocrinology and Metabolism. - Bethesda, USA : American Physiological Society. - 0193-1849 .- 1522-1555. ; 291:5, s. E1044-50
-
Journal article (peer-reviewed)abstract
- Critically ill patients treated for multiple organ failure often develop muscle dysfunction. Here we test the hypothesis that mitochondrial and energy metabolism are deranged in leg and intercostal muscle of critically ill patients with sepsis-induced multiple organ failure. Ten critically ill patients suffering from sepsis-induced multiple organ failure and requiring mechanical ventilation were included in the study. A group (n = 10) of metabolically healthy age- and sex-matched patients undergoing elective surgery were used as controls. Muscle biopsies were obtained from the vastus lateralis (leg) and intercostal muscle. The activities of citrate synthase and mitochondrial respiratory chain complexes I and IV and concentrations of ATP, creatine phosphate, and lactate were analyzed. Morphological evaluation of mitochondria was performed by electron microscopy. Activities of citrate synthase and complex I were 53 and 60% lower, respectively, in intercostal muscle of the patients but not in leg muscle compared with controls. The activity of complex IV was 30% lower in leg muscle but not in intercostal muscle. Concentrations of ATP and creatine phosphate were, respectively, 40 and 34% lower, and lactate concentrations were 43% higher in leg muscle but not in intercostal muscle. We conclude that both leg and intercostal muscle show a twofold decrease in mitochondrial content in intensive care unit patients with multiple organ failure, which is associated with lower concentrations of energy-rich phosphates and an increased anaerobic energy production in leg muscle but not in intercostal muscle.

Metabolism and catabolism in hip fracture patients : nutritional and anabolic intervention—a review
- 2006
-
In: Acta Orthopaedica. - New York, USA : Medical Journals Sweden AB. - 1745-3674 .- 1745-3682. ; 77:5, s. 741-747
-
Research review (peer-reviewed)abstract
- Patients suffering from hip fracture are known to be at risk of catabolism and protein-energy malnutrition. In this review we discuss the pathogenesis of hip fracture-related catabolism per- and postoperatively. We also describe the consequences of malnutrition after a hip fracture and summarize studies that have evaluated the effect of nutritional or anabolic treatment of these patients. There has been relatively little published on the effects of nutritional and anabolic pharmacological interventions for improvement of nutritional status and on the role of nutritional status in clinical outcomes. Even so, there have been 19 randomized studies in this field. 12 studies evaluated nutritional supplementation or protein supplementation. 6 found improved clinical outcome with fewer complications, faster recovery and shorter length of hospital stay, whereas the others reported no difference in clinical outcome. For pharmacological interventions, the outcomes have been even less clear. Supplementation studies in general appear to be underpowered or suffer logistic problems. Studies of higher scientific quality are needed, and enteral feeding, anabolic treatment and multimodal approaches need to be evaluated in greater depth.

Epidermoid anal cancer : a review of a population-based series of 308 consecutive patients treated according to prospective protocols
- 2005
-
In: International Journal of Radiation Oncology, Biology, Physics. - New York, USA : Elsevier. - 0360-3016 .- 1879-355X. ; 61, s. 92-102
-
Research review (peer-reviewed)abstract
- Purpose: The primary therapy in epidermoid anal cancer is radiotherapy, generally with chemotherapy. The use of neoadjuvant chemotherapy has been infrequently reported in the literature. This study presents results from a large population-based series and provides comparisons between different treatments.Methods and materials: Between 1985 and 2000, 308 patients with invasive epidermoid anal cancer were diagnosed in the Stockholm Health Care Region. Treatment was given according to defined protocols. External beam radiotherapy alone or with concomitant bleomycin and neoadjuvant chemotherapy followed by radiotherapy alone were the primary treatments. Radical surgery was reserved for poor responders or recurrences. Data were reviewed with regard to treatment, outcome, and prognostic factors.Results: Among the 276 patients (90%) treated with curative intent, 264 (96%) received treatment in accordance with the protocols. The overall 5-year survival rate was 68%. Among the 142 patients with locally advanced tumors (T > or =4 cm or N+), patients treated with neoadjuvant platinum-based chemotherapy (n = 91) had significantly better complete response rates compared with patients treated with radiotherapy with or without bleomycin (n = 51) (92% vs. 76%, p < 0.01). A significantly increased overall 5-year survival rate was also found among patients receiving neoadjuvant therapy (63% vs. 44%, p < 0.05).Conclusion: Structured treatment protocols result in favorable outcome on a population level. The results further suggest a significant therapeutic gain from including neoadjuvant chemotherapy in the treatment of locally advanced anal cancer.
