Clinical Impact of Weight Loss During Hospitalization on Prognosis After Pancreatic Surgery.

Purpose This study aimed to elucidate the relationship between early-stage weight loss (WL) during hospitalization after pancreatic surgery and prognosis and investigate risk factors affecting WL. Methods We included 68 patients diagnosed with pancreatic ductal adenocarcinoma (PDAC) who underwent radical surgery. The %WL value was calculated based on the percentage of body weight at discharge compared with the body weight at admission. High WL was defined as %WL >10%. We initially evaluated the association between %WL and postoperative survival using the Kaplan-Meier method. Subsequently, we analyzed the factors affecting %WL using a logistic regression model. Results In terms of overall survival (OS), the high %WL group exhibited a significantly worse prognosis than the low %WL group (p=0.043). Univariate analysis revealed a hazard ratio of 2.244 (95% confidence interval (CI), 1.006-5.006; p=0.048) for high %WL in relation to overall survival. Multivariate analysis identified an operative time >450 min (odds ratio, 17.8; 95% confidence interval, 1.01-312.42; p=0.049) and postoperative complications (odds ratio, 12.1; 95% confidence interval, 2.01-72.79; p<0.01) as independent risk factors for high %WL. Conclusion Preventing high %WL by streamlining surgical procedures, minimizing postoperative complications, and implementing medical nutritional therapy (MNT) is imperative to improve the prognosis of patients with PDAC.

Meta-analysis of bone mineral density in adults with phenylketonuria

BackgroundLifelong management of phenylketonuria (PKU) centers on medical nutrition therapy, including dietary phenylalanine (Phe) restriction in addition to Phe-free or low-Phe medical foods/protein substitutes. Studies have reported low bone mineral density (BMD) in mixed-age PKU populations, possibly related to long-term Phe restriction. Therefore, a meta-analysis investigating BMD specifically in adults with PKU was conducted.MethodsStudies reporting BMD-related outcomes were identified from a systematic literature review evaluating somatic comorbidities experienced by adults with PKU on a Phe-restricted diet (searched February 1, 2022, updated November 1, 2023). Risk of study bias was assessed (Scottish Intercollegiate Guidelines Network checklists). The primary outcome of the meta-analysis was pooled mean BMD Z-scores of different bones. Secondary outcomes were the prevalence of low BMD Z-scores at pre-specified thresholds. Subgroup analyses of mean BMD Z-scores (decade of study publication, controlled versus uncontrolled blood Phe levels, gender) were conducted.ResultsBMD-related data from 4097 individuals across 10 studies rated as at least acceptable quality were included. Mean BMD Z-scores were statistically significantly lower compared with an age-matched control or reference (non-PKU) population, across bones, but still within the expected range for age (> -2.0): lumbar spine (seven studies, n = 304), -0.63 (95% confidence interval (CI): -0.74, -0.52); femoral neck (four studies, n = 170), -0.74 (95% CI: -1.25, -0.22); radius (three studies, n = 114), -0.77 (95% CI: -1.21, -0.32); total body (four studies, n = 157), -0.61 (95% CI: -0.77, -0.45). The small number of observations in the subgroup analyses resulted in a high degree of uncertainty, limiting interpretation. Estimated prevalence of BMD Z-scores ≤ -2.0 was 8% (95% CI: 5%, 13%; four studies, n = 221) and < -1.0 was 42% (95% CI: 35%, 51%; five studies, n = 144).ConclusionsAdults with PKU had lower BMD Z-scores than the reference (non-PKU) population but < 1 in 10 were below the expected range for age. The low number of studies prevents identification of which population characteristics are most impacting BMD.This meta-analysis was supported by BioMarin Pharmaceutical Inc., Novato, CA and is registered with the Research Registry (reviewregistry1476).

Ultra-processed foods cause weight gain and increased energy intake associated with reduced chewing frequency: A randomized, open-label, crossover study.

To elucidate the effects of ultra-processed foods (UPFs) on body weight and ad libitum energy intake compared with non-UPFs. In this randomized, open-label crossover study conducted at the University of Tokyo Hospital, overweight/obese Japanese male participants were randomly assigned (1:1) to start the study with consumption of either UPFs or non-UPFs for 1 week, followed by a 2-week washout period, before crossing over to the alternate food diet for 1 week. Individuals with diabetes, hypertension or any other medical conditions who visited a hospital regularly were excluded. The meals were designed to be matched for the total energy and macronutrient levels. The primary outcome was the difference in the body weight change between the UPF and non-UPF periods. The differences in the average daily energy intake and chewing frequency were assessed as one of the prespecified secondary outcomes. Nine eligible participants were randomly assigned to start the study with either UPFs or non-UPFs. All participants completed the study. During the UPF period, participants gained 1.1 kg more weight (95% confidence interval 0.2 to 2.0; P = .021) and consumed 813.5 kcal more per day (342.4 to 1284.7; P = .0041) compared with during the non-UPF period. Regarding the chewing frequency, the number of chews per calorie was significantly lower during the UPF period (P = .016). Consumption of UPFs causes significant weight gain. Medical nutritional therapy focused on reducing the consumption of UPFs could be an effective strategy for preventing obesity.

A Randomized Trial of the Efficacy of Three Weight Loss Diet Interventions in Overweight/Obese with Polycystic Ovary Syndrome.

Polycystic Ovary Syndrome (PCOS) is a highly prevalent, complex, heterogeneous, polygenic endocrine disorder characterized by metabolic and reproductive dysfunction that affects 8-13% of women of reproductive age worldwide. The pathogenesis of PCOS has not been fully clarified and includes genetics, obesity, and insulin resistance (IR). Oxidative stress (OS) of PCOS is independent of obesity. It can induce IR through post-insulin receptor defects, impair glucose uptake in muscle and adipose tissue, and exacerbate IR by reducing insulin secretion from pancreatic β-cells. To investigate the effects of Calorie Restricted Diet (CRD), High Protein Diet (HPD), and High Protein and High Dietary Fiber Diet (HPD+HDF) on body composition, insulin resistance, and oxidative stress in overweight/obese PCOS patients. A total of 90 overweight/obese patients with PCOS were selected to receive an 8- week medical nutrition weight loss intervention at our First Hospital of Peking University, and we randomly divided them into the CRD group (group A), the HPD group (group B), and the HPD+HDF group (group C), with 30 patients in each group. We measured their body composition, HOMA-IR index, and oxidative stress indicators. The t-test, Mann-Whitney U test, analysis of variance (ANOVA), and Kruskal-Wallis H test were used to compare the efficacy of the three methods. After eight weeks, the body weights of the three groups decreased by 6.32%, 5.70% and 7.24%, respectively, and the Visceral Fat Area (VFA) values decreased by 6.8 cm2, 13.4 cm2 and 23.45 cm2, respectively, especially in group C (p <0.05). The lean body mass (LBM), also known as the Fat-Free Mass (FFM) values of group B and group C after weight loss, were higher than that of group A (p <0.05). After weight loss, the homeostatic model assessment of insulin resistance (HOMA-IR) index and malondialdehyde (MDA) were decreased. Superoxide dismutase (SOD) was increased in all three groups (p <0.05), and the changes in SOD and MDA in group B and group C were more significant (p <0.05). HOMA-IR index positively correlated with body mass index (BMI) (r=0.195; p <0.05); MDA positively correlated with percent of body fat (PBF) (r=0.186; p <0.05) and HOMA-IR index (r=0.422; p <0.01); SOD positively correlated with LMI/FFMI (r=0.195; p <0.05), negatively correlated with HOMA-IR index (r=-0.433; p <0.01). All three diets were effective in reducing the body weight of overweight/obese patients with PCOS by more than 5% within 8 weeks and could improve both insulin resistance and oxidative stress damage. Compared with CRD, HPD and HPD+HDF diets could better retain lean body mass and significantly improve oxidative stress damage.

Desnutrición relacionada con la enfermedad

Malnutrition is one of the main public health problems that affects the whole world, not just the most disadvantaged societies. Disease-related malnutrition (DRM) is a new acronym for an old health problem that identifies the pairing of malnutrition and disease. DRM has a very high prevalence and negative consequences for the patient and national health systems. Classically, defining malnutrition has been considered a complex issue. The GLIM criteria for diagnosing malnutrition have become a turning point in the approach to DRM, allowing the scientific community to use the same language regarding this clinical entity. Morphofunctional assessment has entailed a fundamental paradigm shift in its diagnostic approach. Nutritional care is a human right that includes screening, diagnosis, feeding, and evidence-based medical nutrition therapy.

Chinese expert consensus on the application of electrolytes in parenteral nutrition (2024 edition)

As essential nutrients for human beings, electrolytes play a central role in nutritional and metabolic support treatment. To further standardize the use of electrolyte preparations in parenteral nutrition, the China International Exchange and Promotive Association for Medical and Health Care Clinical Nutrition Health Branch, Chinese Medical Doctor Association Nutritionist Professional Committee, Chinese Society of Parenteral and Enteral Nutrition, and Chinese Nutrition Society Branch of Clinical Nutrition, invited authoritative experts in the fields of critical medicine, emergency medicine, internal medicine, surgery, and pharmacology in China to create this expert consensus. This consensus was based on the latest guidelines and evidence-based medicine at home and abroad, and combined with the actual clinical medical environment in China. This consensus covered the following topics: electrolytes monitoring during parenteral nutrition, risk assessment and nutritional treatment of refeeding syndrome, electrolytes supplementation during parenteral nutrition for various diseases (including severe diseases, heart failure, post-surgical short bowel syndrome, perioperative period, trauma, diabetic foot, chronic kidney disease, liver disease, neonates), and the compatibility principles of electrolyte preparations in parenteral nutrition. Finally, 13 clinical questions and 26 recommendations were proposed aiming at providing scientific, standardized, and practical guidance for the rational application of electrolytes in parenteral nutrition.

Weight gain during pregnancy and the probability of macrosomia in women with gestational diabetes

Objective. To analyze the association between gestational weight gain in women with gestational diabetes and an increased risk of macrosomia. Materials and methods. Cohort study with 139 pregnant women screened by a single-step oral glucose tolerance curve between 24-28 weeks of gestation were confirmed with gestational diabetes and sent to a hospital. Pre-pregnancy body mass index (BMI) was calculated from pre-pregnancy weight. Weight was measured at each prenatal consultation. The reference category was women with normal prenatal BMI who gained appropriate weight during pregnancy. At each visit, medical nutrition therapy (MNT) consisted of nutritional counseling, physical activity plan, and insulin therapy. Compliance with MNT was measured by capillary glucose measurements taken by each participant at home. Results. 74.8% were primiparous, and 28.8% had normal pre-pregnancy BMI. The no linear logistic regression model showed women with normal pre-pregnancy BMI had twice (OR= 2.08, 95%CI: 1.07,4.05) the possibility of macrosomia, compared to mothers with overweight or obesity, adjusting for Capurro index, number of children in the family, and percent of compliance MNT. Macrosomia was the most prevalent childhood complication (12.3%). Conclusion. Women with normal pre-pregnancy BMI who gained more weight during pregnancy were at higher risk of having macrosomic infants.

Going Viral: Sharing of Misinformation by Social Media Influencers

This paper tackles the issue of health and well-being misinformation, the dissemination of false or misleading information related to medical treatments, diseases, mental health, nutrition, exercise or general well-being, propagated by social media influencers. It investigates the virality of misinformation posts by TikTok and Instagram influencers exploring users’ appraisals and their sharing tendencies. Grounded in social influence and cognitive appraisal theories (CAT), three online experimental studies dissect the dynamics of virality, user comments and their effects on perceived deception, parasocial interaction and sharing intent. The results of Study 1 demonstrate heightened post virality reduces perceived deception, fostering stronger parasocial connections and sharing intentions. Conversely, lower virality levels heighten deception perceptions. In Study 2, critical comments are shown to enhance deception in high virality posts. Whereas supportive comments are shown to enhance the indirect effect of low virality posts on sharing intentions, via deception and parasocial interaction. The study contributes by demonstrating how social influence theory and CAT together explain how social media influencer misinformation posts based on their virality and user responses are likely to be shared and what consumer appraisals explain this effect. It provides directions of how marketers can tackle this issue.

Neonatal outcomes of gestational diabetes mellitus (GDM) mothers: A cross-sectional study comparing medical nutritional therapy, metformin, and insulin treatments at a tertiary care centre

Gestational Diabetes Mellitus (GDM) poses a rising global health challenge, affecting 10-14.3% of pregnant women. This study aimed to investigate and compare neonatal outcomes among mothers with GDM treated with Medical Nutritional Therapy (MNT), metformin, and insulin at a tertiary care center. Understanding the impact of these treatments on neonatal outcomes is crucial for optimal care.Conducted at a tertiary care center in Chennai, India, this cross-sectional study included 160 GDM mothers identified through medical records from December 2021 to December 2023. Inclusion criteria covered women aged 18 and above, experiencing singleton pregnancies, diagnosed with GDM, and maintaining regular follow-up. Data analysis included birth weight, Apgar scores, neonatal hypoglycemia, and preterm birth rates. Multinomial logistic regression determined adjusted odds ratios.The study analyzed the distribution of perinatal factors among 160 neonates, revealing that 41.3% were delivered vaginally, while 58.8% were through cesarean section. The majority were preterm, with 118 being appropriate for gestational age.Neonatal Intensive Care Unit (ICU) admission was noted in 34.4% of cases, while 62.7% did not. Neonatal hypoglycemia was observed in 36.3% of cases, and seizures were present in 19.4%. Apgar scores were low in 23.8% of cases.A multinomial logistic analysis found that the Metformin, Insulin, and Metformin + Insulin groups had significantly higher odds of having a Cesarean section compared to the diet-only group. However, the Metformin group had lower odds of preterm birth, NICU admission, neonatal hypoglycemia, seizures, and AGA. The Metformin group had higher odds of LGA and Apgar score &amp;#60;7 at both the 1st and 5th minutes. No significant differences were found in the odds of preterm birth, NICU admission, or seizures between the diet-only and Metformin groups.This pioneering South Indian study of 160 neonates born to GDM mothers compared different treatment options. Metformin, alone or with insulin, showed comparable neonatal outcomes to insulin. Caution in GDM deliveries is recommended for optimal well-being. The study emphasizes the need for further research considering maternal outcomes as potential confounders to comprehensively understand GDM treatments and neonatal outcomes.

Evaluation of the Effect of Nutrition Education on Osteopathic Medical Students' Personal Nutrition Choices and Incorporation Into Future Medical Practice.

Our current research project evaluates the impact of nutrition education on the medical student's personal nutrition goals and the likelihood of incorporating nutrition needs into patient evaluation and treatment plans in future practice. The growing popularity of lifestyle medicine has further emphasized the importance of nutrition in the treatment of all patients, especially those suffering from chronic diseases. The paucity of formal medical nutrition education in medical school curricula leaves a significant gap in the knowledge base of physicians in practice. In an attempt to close the gap, we increased nutrition education in first-year osteopathic medical students by establishing a nutrition course emphasizing modern competencies and their importance in clinical practice. Methods: The course evaluation utilized a two-group quasi-experimental pre-test/post-test study design. The intervention group consisted of medical students participating in the newly established course, and the control group consisted of second-year medical students who had not taken the course as part of their curriculum. Information was collected about students' knowledge, attitudes, behaviors around nutrition, their plans to pursue a residency with a focus on culinary medicine and incorporate medical nutrition into their medical practice in the future, and their intention to incorporate culinary medicine into future treatment plans. Participation rates within a voluntary culinary medicine interest group were also tracked. Students in the intervention group were 26% more likely to report that proper nutrition for patient care had been addressed in coursework. This suggests that medical students exposed to the medical nutrition course have received more training that is critical in proper patient care than students in the control group. Students in the intervention group were 93% more likely to believe that proper nutrition can be used to prevent disease. Lastly, significantly more students in the intervention group (33% more) intend to explore residency programs with a focus on culinary medicine than those students in the control group. These results demonstrate that nutritional education promotes an awareness of the effectiveness of nutritional counseling in disease prevention and management. Furthermore, it will hopefully prompt future physicians to consider nutritional counseling during their clinical rotations, through residency, and into their independent practice. The presentation of nutrition in the first year of medical school is critical to develop increasing numbers of primary care physicians that promote the importance of nutrition and a healthy lifestyle for patients.

A knowledge-based decision support system to support family doctors in personalizing type-2 diabetes mellitus medical nutrition therapy

BackgroundType-2 Diabetes Mellitus (T2D) is a growing concern worldwide, and family doctors are called to help diabetic patients manage this chronic disease, also with Medical Nutrition Therapy (MNT). However, MNT for Diabetes is usually standardized, while it would be much more effective if tailored to the patient. There is a gap in patient-tailored MNT which, if addressed, could support family doctors in delivering effective recommendations. In this context, decision support systems (DSSs) are valuable tools for physicians to support MNT for T2D patients – as long as DSSs are transparent to humans in their decision-making process. Indeed, the lack of transparency in data-driven DSS might hinder their adoption in clinical practice, thus leaving family physicians to adopt general nutrition guidelines provided by the national healthcare systems. MethodThis work presents a prototypical ontology-based clinical Decision Support System (OnT2D- DSS) aimed at assisting general practice doctors in managing T2D patients, specifically in creating a tailored dietary plan, leveraging clinical expert knowledge. OnT2D-DSS exploits clinical expert knowledge formalized as a domain ontology to identify a patient's phenotype and potential comorbidities, providing personalized MNT recommendations for macro- and micro-nutrient intake. The system can be accessed via a prototypical interface. ResultsTwo preliminary experiments are conducted to assess both the quality and correctness of the inferences provided by the system and the usability and acceptance of the OnT2D-DSS (conducted with nutrition experts and family doctors, respectively). ConclusionsOverall, the system is deemed accurate by the nutrition experts and valuable by the family doctors, with minor suggestions for future improvements collected during the experiments.

The latest evidence and clinical guidelines for use of meal replacements in very-low-calorie diets or low-calorie diets for the treatment of obesity.

Obesity is a complex chronic disease with increasing prevalence across the globe. Medical nutrition therapy (MNT) is an important component of obesity treatment, and low-calorie diets (LCDs) and very-low-calorie diets (VLCDs) are part of the MNT toolbox. This narrative review focuses on the latest evidence and clinical guidelines regarding the use and impact of meal replacements (MRs) as part of LCDs/VLCDs for the treatment of obesity and some associated complications. MRs can be used in conjunction with food as partial diet replacement (PDR) or can be used exclusively to serve as the sole source of dietary energy (total diet replacement [TDR]). Use of MR may be associated with better control of cravings and hunger typically observed during reduced calorie intake through effects of ketosis or stimuli narrowing, although the exact mechanisms for these effects remain unclear. Several clinical guidelines have endorsed the use of MRs as a part of MNT for obesity, primarily based on evidence that shows an average weight reduction of ~10 kg or more with TDR over at least 12 months in large, randomized controlled trials. When compared to usual care controls, these effects are 6-8 kg greater, and when compared to food-based diets, the effects are nearly twice the effect of a food-based diet. MR-based diets have been found to be safe and associated with improvements in quality of life. These diets are also effective for improving key cardiometabolic health outcomes, including dysglycaemia, blood pressure, lipids, and metabolic associated fatty liver. The effectiveness, safety, and associated health improvement makes MRs use a valuable strategy for several higher risk clinical scenarios where weight reduction is indicated.

Assessing Weight Stigma: Validating Attitudes and Beliefs Questionnaires Among Future Healthcare Professionals.

Background This study aimedto establish the reliability and validity of the Anti-Fat Attitudes (AFA) questionnaire and the Beliefs About Obese Persons (BAOP) scale. Methodology A convenience sample of 257 students from three distinct sections of the University of Medicine and Pharmacy "Grigore T. Popa" Iasi (Medical Faculty, Nutrition and Dietetics, and Nursing) participated in an observational study. Construction validity was tested with exploratory factor analysis. The students completed a form containing sociodemographic data, the AFA questionnaire, and the BAOP scale. Weight and height were self-reported and used to determine the body mass index. Results The value of the Cronbach alpha coefficient for the AFA questionnaire indicated adequate internal consistency (0.862). The exploratory factor analysis identified the following three factors corresponding to the original questionnaire: Dislike, Fear of Fat, and Willpower. We validated a single-factor structure of the BAOP scale, which had adequate internal consistency (0.781). There were statistically significant differences (AFA: p = 0.02; BAOP: p = 0.03) between the scores of the students from Nutrition and Dietetics, Nursing, and General Medicine. Conclusions This study demonstrated that the AFA questionnaire and the BAOP scale could be used to evaluate weight stigma in healthcare students, providing a useful tool to assess the effects of weight stigma awareness interventions in this population.

Complications in Patients with Surgically Altered Gastrointestinal Anatomy Undergoing Endoscopic Retrograde Cholangiopancreatography: 15-Year Experience at a Tertiary Care Center in Latin America.

Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure, but it poses challenges in patients with surgically altered gastrointestinal anatomy (SAGA). Alternative techniques like single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), or push enteroscopy (PE) have been used, albeit with potential complications. Limited Latin American data exists on ERCP complications in SAGA patients. Our goal is to describe complications of ERCP in SAGA at a national referral institution. Retrospective, single-center cohort study. All SAGA ERCP procedures performed at the Gastrointestinal Endoscopy Department of the National Institute of Medical Sciences and Nutrition Salvador Zubirán from January 2008 to May 2023 were included. Extracted data from records included procedure specifics, endoscope type, success, and complications. Complications were evaluated during procedure and 28-day post-procedure and classified using the AGREE system. A total of 266 procedures in 174 patients were included, 74% were women, and the median age was 44years. Predominant modified anatomy was Roux-en-Y biliary reconstruction (79%), followed by Whipple procedure (13%) and subtotal gastrectomy with Roux-en-Y reconstruction (6.0%). The main indications were cholangitis with stricture (31%), stricture (19%), and cholangitis (19%). DBE was used in 89%, PE in 7.5%, and SBE in 3.4%. Success rates were 77% endoscopic, 72% technical, and 69% therapeutic; in 30%, the procedure was unsuccessful. Complications happened in 18% of cases, most commonly cholangitis (7.5%), followed by perforation (2.6%) and hemorrhage (1.9%). According to the AGREE classification, 10.9% were grades 1 and 2, 6.4% were grade 3, and 0.4% were grade 4 complications. No significant differences emerged between groups with and without complications. Procedures increased over time, but complications and unsuccessful procedures remained stable. ERCP complications align with international data, often not requiring invasive treatment. Enhanced exposure to such cases correlates with fewer complications and failures. Prospective studies are essential to identify complication and failure predictors.

A Novel Machine-Learning Algorithm to Predict the Early Termination of Nutrition Support Team Follow-Up in Hospitalized Adults: A Retrospective Cohort Study.

For hospitalized adults, it is important to initiate the early reintroduction of oral food in accordance with nutrition support team guidelines. The aim of this study was to develop and validate a machine learning-based algorithm that predicts the early termination of medical nutritional therapy (the transition to oral feeding). This retrospective cohort study included consecutive adult patients admitted to the Hacettepe hospital (from 1 January 2018 to 31 December 2022). The outcome of the study was the prediction of an early transition to adequate oral feeding before discharge. The dataset was randomly (70/30) divided into training and test datasets. We used six ML algorithms with multiple features to construct prediction models. ML model performance was measured according to the accuracy, area under the receiver operating characteristic curve, and F1 score. We used the Boruta Method to determine the important features and interpret the selected features. A total of 2298 adult inpatients who were followed by a nutrition support team for medical nutritional therapy were included. Patients received parenteral nutrition (1471/2298, 64.01%), enteral nutrition (717/2298, 31.2%), or supplemental parenteral nutrition (110/2298, 4.79%). The median (interquartile range) Nutritional Risk Screening (NRS-2002) score was 5 (1). Six prediction algorithms were used, and the artificial neural network and elastic net models achieved the greatest area under the ROC in all outcomes (AUC = 0.770). Ranked by z-value, the 10 most important features in predicting an early transition to oral feeding in the artificial neural network and elastic net algorithms were parenteral nutrition, surgical wards, surgical outcomes, enteral nutrition, age, supplemental parenteral nutrition, digestive system diseases, gastrointestinal complications, NRS-2002, and impaired consciousness. We developed machine learning models for the prediction of an early transition to oral feeding before discharge. Overall, there was no discernible superiority among the models. Nevertheless, the artificial neural network and elastic net methods provided the highest AUC values. Since the machine learning model is interpretable, it can enable clinicians to better comprehend the features underlying the outcomes. Our study could support personalized treatment and nutritional follow-up strategies in clinical decision making for the prediction of an early transition to oral feeding in hospitalized adult patients.

Diabetes-specific formula with standard of care improves glycemic control, body composition, and cardiometabolic risk factors in overweight and obese adults with type 2 diabetes: results from a randomized controlled trial.

Medical nutrition therapy is important for diabetes management. This randomized controlled trial investigated the effects of a diabetes-specific formula (DSF) on glycemic control and cardiometabolic risk factors in adults with type 2 diabetes (T2D). Participants (n = 235) were randomized to either DSF with standard of care (SOC) (DSF group; n = 117) or SOC only (control group; n = 118). The DSF group consumed one or two DSF servings daily as meal replacement or partial meal replacement. The assessments were done at baseline, on day 45, and on day 90. There were significant reductions in glycated hemoglobin (-0.44% vs. -0.26%, p = 0.015, at day 45; -0.50% vs. -0.21%, p = 0.002, at day 90) and fasting blood glucose (-0.14 mmol/L vs. +0.32 mmol/L, p = 0.036, at day 90), as well as twofold greater weight loss (-1.30 kg vs. -0.61 kg, p < 0.001, at day 45; -1.74 kg vs. -0.76 kg, p < 0.001, at day 90) in the DSF group compared with the control group. The decrease in percent body fat and increase in percent fat-free mass at day 90 in the DSF group were almost twice that of the control group (1.44% vs. 0.79%, p = 0.047). In addition, the percent change in visceral adipose tissue at day 90 in the DSF group was several-fold lower than in the control group (-6.52% vs. -0.95%, p < 0.001). The DSF group also showed smaller waist and hip circumferences, and lower diastolic blood pressure than the control group (all overall p ≤ 0.045). DSF with SOC yielded significantly greater improvements than only SOC in glycemic control, body composition, and cardiometabolic risk factors in adults with T2D.
