The clinical and economic impact of the use of diabetes-specific enteral formula on ICU patients with type 2 diabetes

The Application and Mechanism Analysis of Enteral Nutrition in Clinical Management of Chronic Diseases

Chronic diseases have emerged as a significant challenge in global public health due to their complex etiologies, prolonged disease courses, and high treatment costs. With the aging population and changes in lifestyle, the number of patients with chronic diseases has increased dramatically, which has brought heavy burden to families and society. Chronic diseases are often accompanied by digestive and absorptive disorders as well as metabolic disorders, resulting in insufficient nutrient intake, further worsening the condition and weakening the physique. Therefore, the importance of nutritional intervention in chronic disease management has become increasingly prominent. As an important means of nutritional intervention, enteral nutrition plays a key role in improving the nutritional status of patients, promoting rehabilitation, shortening hospital stay and so on, thereby providing a new solution for chronic disease management. This article reviews the current application status, mechanism of action and comprehensive benefit of enteral nutrition in the clinical management of chronic diseases. Through systematic review and analysis of existing research findings, the specific application effects and mechanisms of enteral nutrition in chronic disease management are clarified. This review aims to promote the popularization and application of enteral nutrition, in order to effectively improve patients' treatment outcomes and quality of life, provide scientific evidence for the optimization of clinical management strategies for chronic diseases, and offer theoretical support for the development of enteral nutrition products, and thereby drive the continuous improvement of chronic disease management.

Dietary recommendations for people with diabetes in special situations: a position statement report by Arabic Association for the Study of Diabetes and metabolism (AASD)

BACKGROUND

Diabetes is a significant global health concern. Regional factors play a crucial role in determining the appropriate diet for patients.

MAIN BODY

The Arabic Association for the Study of Diabetes and Metabolism has developed a position statement that addresses the dietary needs of patients in the context of low income and cultural dietary habits. This statement aims to explore the most suitable diet for Middle East and North Africa (MENA) region and provide guidance for physicians to overcome barriers in optimal care. While most dietary guidelines focus on uncomplicated diabetes, it's essential to recognize that diabetes often coexists with other common diseases in our region.

CONCLUSION

International guidelines cannot be directly applied to the Egypt and Arab countries due to cultural and dietary differences. Our position statement shares valuable insights into managing diabetes in special situations and diverse clinical settings within this region. These recommendations are flexible, considering personal, cultural, and traditional differences.

Glycemic Control in Diabetic Patients Receiving a Diabetes-Specific Nutritional Enteral Formula: A Case Series in Home Care Settings

BACKGROUND AND AIM

In patients with Diabetes Mellitus (DM), Enteral Nutrition (EN) is associated with less hyperglycemia and lower insulin requirements compared to Parenteral Nutrition (PN). The primary aim of this study was to assess changes in glycemic control (GC) in DM patients on EN therapy. The secondary objectives included evaluating the impact of the specialized formula on various clinical parameters and the tolerability of the nutritional formula by monitoring potential gastrointestinal side effects.

METHODS

We report a case series on the effects of a Diabetes-Specific Formula (DSF) on GC, lipid profile (LP), and renal and hepatic function in a DM cohort receiving EN support.

RESULTS

Twenty-two DM subjects with total dysphagia (thirteen men, nine women) on continuous EN were observed. The use of a DSF in EN was associated with an improvement in glycemic indices across all patients studied, leading to a reduction in average insulin demand. No hospitalizations were reported during the study period.

CONCLUSION

The study demonstrated that the use of DSFs in a multi-dimensional home care management setting can improve glycemic control, reduce glycemic variability and insulin need, and positively impact the lipid profile of the DM cohort. The metabolic improvements were supported by the clinical outcomes observed.

ESPEN practical and partially revised guideline: Clinical nutrition in the intensive care unit

Following the new ESPEN Standard Operating Procedures, the previous 2019 guideline to provide best medical nutritional therapy to critically ill patients has been shortened and partially revised. Following this update, we propose this publication as a practical guideline based on the published scientific guideline, but shortened and illustrated by flow charts. The main goal of this practical guideline is to increase understanding and allow the practitioner to implement the Nutrition in the ICU guidelines. All the items discussed in the previous guidelines are included as well as special conditions.

Glycemic Management of Hospitalized Patients Receiving Nutrition Support

Enteral nutrition (EN) and parenteral nutrition (PN) increase the risk of hyperglycemia and adverse outcomes, including mortality, in patients with and without diabetes. A blood glucose target range of 140-180 mg/dL is recommended for hospitalized patients receiving artificial nutrition. Using a diabetes-specific EN formula, lowering the dextrose content, and using a hypocaloric PN formula have all been shown to prevent hyperglycemia and associated adverse outcomes. Insulin, given either subcutaneously or as a continuous infusion, is the mainstay of treatment for hyperglycemia. However, no subcutaneous insulin regimen has been shown to be superior to others. This review summarizes the evidence on and provides recommendations for the treatment of EN- and PN-associated hyperglycemia and offers strategies for hypoglycemia prevention. The authors also highlight their institution's protocol for the safe use of insulin in the PN bag. Randomized controlled trials evaluating safety and efficacy of targeted insulin therapy synchronized with different types of EN or PN delivery are needed.

Association of specialized enteral nutrition with glycemic control and clinical outcomes in critically ill patients: A meta-analysis of randomized controlled trials

OBJECTIVE

To evaluate the association of glycemic-control formulae (GCF) with measurements of glycemic control and clinical outcomes compared to standard enteral formulae (SF) in critically ill patients.

DATA SOURCES

MEDLINE, EMBASE, Scopus and the Cochrane Central Register of Controlled Trials were searched from inception up to January, 2021.

STUDY SELECTION

RCTs that assessed the effects of GCF relative to SF in adult critically ill patients.

DATA EXTRACTION

Measurements of glycemic control were the primary outcomes. Secondary outcomes included insulin requirements, mechanical ventilation (MV), length of intensive care unit (ICU) stay and mortality. Two authors independently extracted data and assessed risk of bias using the Cochrane's RoB 2 tool and the GRADE approach was used to assess the quality of evidence.

DATA SYNTHESIS

Ten studies (12 reports, 685 patients) were included. The use of GCFs was associated with lower blood glucose (WMD, -16.06 mg/dL; 95% CI -23.48 to -8.63; I² = 47%) and lower daily administered insulin (WMD, -7.20 IU; 95% CI -13.92 to -0.48; I² = 53%). Glycemic variability, measured by the coefficient of variation, was also associated with the use of GCFs (WMD, -6.84%; 95% CI, -13.57 to -0.11; I² = 95%). In contrast, analyses for length of ICU stay (WMD, -0.12, 95% CI -1.77 to 1.52; I² = 0%), duration of MV (WMD, -0.34 days; 95% CI, -1.72 to 1.04; I² = 0%) and mortality (RR, 1.13; 95% CI 0.82 to 1.56; I² = 0%) were not statistically significant. Quality of evidence ranged from low to very low, and only one study was judged as at low risk of bias.

CONCLUSIONS

In this meta-analysis, GCFs were significantly associated with lower insulin requirements and improved glycemic control. Although results for clinical outcomes were not statistically significant, there is insufficient evidence to confirm or exclude important differences due to serious imprecision in the effect estimates and overall low quality of evidence. The effects of GCFs on clinical outcomes require confirmation in larger randomized trials.

Diabetes-Specific Nutrition Formulas in the Management of Patients with Diabetes and Cardiometabolic Risk

Food-based dietary management, enhanced with evidence-based commercial products, such as diabetes-specific nutrition formulas (DSNFs), can help control the development, progression, and severity of certain chronic diseases. In this review, evidence is detailed on the use of DSNFs in patients with or at risk for diabetes and cardiometabolic-based chronic disease. Many DSNF strategies target glycemic excursions and cardiovascular physiology, taking into account various elements of healthy eating patterns. Nevertheless, significant research, knowledge, and practice gaps remain. These gaps are actionable in terms of formulating and testing relevant and pragmatic research questions, developing an educational program for the uniform distribution of information, and collaboratively writing clinical practice guidelines that incorporate the evidence base for DSNF. In sum, the benefits of DNSF as part of validated clinical practice algorithms include mitigation of chronic disease progression, cost-savings for the healthcare system, and applicability on a global scale.

ESPEN guideline on clinical nutrition in the intensive care unit

Following the new ESPEN Standard Operating Procedures, the previous guidelines to provide best medical nutritional therapy to critically ill patients have been updated. These guidelines define who are the patients at risk, how to assess nutritional status of an ICU patient, how to define the amount of energy to provide, the route to choose and how to adapt according to various clinical conditions. When to start and how to progress in the administration of adequate provision of nutrients is also described. The best determination of amount and nature of carbohydrates, fat and protein are suggested. Special attention is given to glutamine and omega-3 fatty acids. Particular conditions frequently observed in intensive care such as patients with dysphagia, frail patients, multiple trauma patients, abdominal surgery, sepsis, and obesity are discussed to guide the practitioner toward the best evidence based therapy. Monitoring of this nutritional therapy is discussed in a separate document.

Very high-protein and low-carbohydrate enteral nutrition formula and plasma glucose control in adults with type 2 diabetes mellitus: a randomized crossover trial

BACKGROUND AND OBJECTIVES

Standard enteral nutrition (EN) formulas can  worsen hyperglycemia in diabetic patients. We hypothesized that altering the proportion of macronutrients in a formula; increasing protein while decreasing carbohydrate concentrations would improve glycemic response. The objective of this study was to demonstrate that an EN formula containing a very high concentration of protein (in the form of whey peptides) and low concentration of carbohydrate provide better control of postprandial blood glucose relative to a very high-protein/higher-carbohydrate formula.

SUBJECTS AND METHODS

This was a randomized crossover clinical trial of 12 ambulatory adult subjects with type 2 diabetes. The primary outcome was glycemic response following a bolus of isocaloric amounts of two EN formulas; the secondary outcome was insulin response. Subjects were randomized to the experimental or the control formula, on two separate days, 5-7 days apart.

RESULTS

Mean blood glucose concentrations at 10-180 min post-infusion and mean area under the curve for glucose over 240 min post-infusion were significantly lower with the experimental formula than with the control formula (71.99 ± 595.18 and 452.62 ± 351.38, respectively; p = 0.025). There were no significant differences in the mean insulin concentrations over time, insulinogenic indices, and first-phase insulin measurements.

CONCLUSIONS

An EN formula containing high-protein and low-carbohydrate loads can significantly improve glucose control in subjects with type 2 diabetes in ambulatory settings as evidenced by observed improved glucose control without significant difference in insulin response.

Nutrition and Hyperglycemia Management in the Inpatient Setting (Meals on Demand, Parenteral, or Enteral Nutrition)

PURPOSE OF REVIEW

The goal of this paper is to provide the latest evidence and expert recommendations for management of hospitalized patients with diabetes or hyperglycemia receiving enteral (EN), parenteral (PN) nutrition support or, those with unrestricted oral diet, consuming meals on demand.

RECENT FINDINGS

Patients with and without diabetes mellitus commonly develop hyperglycemia while receiving EN or PN support, placing them at increased risk of adverse outcomes, including in-hospital mortality. Very little new evidence is available in the form of randomized controlled trials (RCT) to guide the glycemic management of these patients. Reduction in the dextrose concentration within parenteral nutrition as well as selection of an enteral formula that diminishes the carbohydrate exposure to a patient receiving enteral nutrition are common strategies utilized in practice. No specific insulin regimen has been shown to be superior in the management of patients receiving EN or PN nutrition support. For those receiving oral nutrition, new challenges have been introduced with the most recent practice allowing patients to eat meals on demand, leading to extreme variability in carbohydrate exposure and risk of hypo and hyperglycemia. Synchronization of nutrition delivery with the astute use of intravenous or subcutaneous insulin therapy to match the physiologic action of insulin in patients receiving nutritional support should be implemented to improve glycemic control in hospitalized patients. Further RCTs are needed to evaluate glycemic and other clinical outcomes of patients receiving nutritional support. For patients eating meals on demand, development of hospital guidelines and policies are needed, ensuring optimization and coordination of meal insulin delivery in order to facilitate patient safety.
