Severe vitamin C deficiency associated with continuous renal replacement therapy: A case report.

Hypovitaminosis C is prevalent in critically ill patients. Continuous renal replacement therapy (CRRT) clears vitamin C, increasing the risk for vitamin C deficiency. However, recommendations for vitamin C supplementation in critically ill patients receiving CRRT vary widely, from 250 mg/day to 12 g/day. This case report describes a patient who developed a severe vitamin C deficiency after prolonged CRRT despite receiving ascorbic acid (450 mg/day) supplementation in her parenteral nutrition. This report summarizes recent research investigating vitamin C status in critically ill patients receiving CRRT, discusses the patient case, and provides recommendations for clinical practice. In critically ill patients receiving CRRT, the authors of this manuscript suggest providing at least 1000 mg/day of ascorbic acid to prevent vitamin C deficiency. Baseline vitamin C levels should be checked in patients who are malnourished and/or have other risk factors for vitamin C deficiency, and vitamin C levels should be monitored thereafter every 1-2 weeks.

Nutritional Supplement Use and Athletic Characteristics among a Sample of NCAA Division I and Division III Student-Athletes.

Due to documented adverse events, understanding the prevalence of nutritional supplements commonly used by athletes is essential. This cross-sectional study used data from a web-based survey conducted in February-March 2022. Participants were Division I (DI) and Division III (DIII) student-athletes of the National Collegiate Athletic Association (NCAA). Chi-square tests were conducted to identify the differences in the prevalence of demographic and athletic characteristics between the divisions. Multivariable odds ratios and 95% confidence intervals were calculated using logistic regression adjusting for potential confounders to determine the predictors of supplement usage. A total of 247 NCAA student-athletes (72.5% Division I, 27.5% Division III) completed the survey, yielding a 24.5% response rate. There were no significant differences between nutritional supplementation and NCAA divisions. Instead, all student-athletes used supplements regardless of division. There were significant differences in race, ethnicity, sports dietitian access, name, image, and likeness (NIL), advisement to consume NS, and knowledge of NS between the divisions (all P-values < 0.01). Unadjusted regression models showed that being in an upper-level academic standing was associated with higher odds of using sports food and ergogenic supplements than student-athletes with a lower-level academic standing. However, multivariable logistic regression analysis revealed that none of the demographic and athletic characteristics significantly affected supplement usage. Allocating resources for access to sports dietitians and supplement education for all divisions may benefit student-athletes knowledge and safety.

Probiotics for the treatment of type 2 diabetes: A review of randomized controlled trials.

With the increasing prevalence of type 2 diabetes mellitus (T2DM), there is increased interest in probiotic supplementation for improving glycaemic control. This review evaluates nine randomized controlled trials that tested the effects of probiotics on glycaemic outcomes including fasting plasma glucose, fasting plasma insulin, haemoglobin A1c, and homeostatic model assessment of insulin resistance among adults with T2DM. Based on the evidence reviewed, multistrain probiotics that contain seven million to 100 billion colony forming units of Lactobacillus acidophilus, Streptococcus thermophilus, Lactobacillus bulgaricus, and/or Bifidobacterium lactis administered for 6 to 12 weeks may be efficacious for improving glycaemic control in adults with T2DM. Further research is needed to understand the role of the gut microbiota and the probiotic dose, medium, and duration of exposure that is most effective for disease management.

Case Report: Transitioning to a Mixed-Oil Intravenous Lipid Emulsion in an Adult Patient Receiving Home Parenteral Nutrition.

A potential risk of long-term parenteral nutrition (PN) is intestinal failure-associated liver disease (IFALD). One recommendation for mitigating risk is limiting the fat dose to reduce the harmful effects of the ω-6 fatty acids, which are the main ingredient in traditional fats. SMOFlipid (SMOF) (Kabi-Fresenius, Bad Homburg, Germany) is a combination of soybean oil, medium-chain triglycerides, olive oil, and fish oil emulsion. This fat source may alleviate the risk of IFALD and improve liver function tests. A patient with a long history of PN reliance and IFALD is presented in this case report. After 4 months on SMOF, total and direct bilirubin levels improved.

Role of Probiotics in Managing Gastrointestinal Dysfunction in Children with Autism Spectrum Disorder: An Update for Practitioners.

Children with autism spectrum disorder (ASD) are 4 times as likely to experience gastrointestinal symptoms as children without ASD. The gut microbiota has increasingly been the subject of investigation as a contributing factor to these symptoms in this population because there is evidence to suggest that alterations in the intestinal microflora are correlated with gastrointestinal and ASD symptom severity. Probiotic therapy has been proposed as a treatment for augmented gastrointestinal symptom severity in children with ASD. This narrative review systematically searched the literature to provide an update for practitioners on the state of the evidence surrounding probiotic therapy in children with ASD as a treatment option for reducing gastrointestinal symptoms. A total of 186 articles were screened and 5 articles met the inclusion criteria. A collective sample of 117 children with ASD is represented and outcomes addressed include improvement in gastrointestinal symptoms as well as influence of probiotic supplementation on the gut microbiota and ASD symptoms and behavior. There is promising evidence to suggest that probiotic therapy may improve gastrointestinal dysfunction, beneficially alter fecal microbiota, and reduce the severity of ASD symptoms in children with ASD. Future research is still warranted in this area because there are methodologic flaws in the available literature and optimal species, strains, dosages, and duration of treatment have not been identified.

Nutritional and dental issues in patients with intellectual and developmental disabilities.

BACKGROUND: People with intellectual and developmental disabilities are among the most disadvantaged and underserved groups of dental patients. Considerable health care disparities for this population have been identified, particularly oral and dental health as well as access to dental care services. People with Down syndrome and cerebral palsy have a variety of nutritional and dental considerations. CONCLUSIONS: These people have a higher prevalence of untreated caries and periodontal disease than the general population and may have higher rates of obesity, edentulism, and chronic oral and systemic diseases. Diet choices may affect the oral health and may play an important role in the systemic health of these people. Suggestions to improve and affect dietary intake are provided. CLINICAL IMPLICATIONS: Health issues within this population require a holistic approach to care. Concerns about oral health and diet must be addressed to support optimal health.
