Background: We investigated the effectiveness of a novel, hunger-based outpatient tube weaning program for children with feeding-tube dependency.

Methods: This interdisciplinary program induced hunger via rapid reduction in tube-fed calories, followed by 2 weeks of daily outpatient mealtime support and regular follow-up. Forty-one children (6.9 months to 12.8 years) participated in this retrospective cohort study.

Results: Before the program, children received a median of 90.0% (interquartile range [IQR]: 75.0%-100%) of caloric intake via tube feeds. At the end of the 2-week program, children received 16.0% (IQR: 0.0%-30.0%) of caloric intake via tube feeds, which further reduced to 1.5% (IQR: 0.0%-33.0%) at 6-months, and 0.0% (IQR: 0.0%-35.0%) at 1-year follow-up. The percentage of participants who ate >30 different foods increased from 4.9% at baseline to 81.5% at 1-year follow-up. The baseline median weight z score of -1.24 (IQR: -1.69 to -0.69) decreased to -1.81 (IQR: -2.77 to -1.02) at 1-year follow-up. A linear mixed-effects model demonstrated that weight z score was significantly higher at baseline and 2-weeks compared to the 1-year follow-up (P < 0.001 and P = 0.001, respectively), but was not significantly different between 6 months and 1 year (P = 0.44). Age was not associated with percentage of caloric intake via tube feeds or number of foods eaten.

Conclusion: Children who participated in the hunger-based tube-weaning program had increased and more varied oral intake 1 year following the intervention. The median weight z score decreased over the year after intervention but did not significantly decrease between 6 and 12 months after the program.

Malnutrition in patients with obesity presents a complex and often overlooked clinical challenge. Although obesity is traditionally associated with overnutrition and excessive caloric intake, it can also coincide with varying degrees of malnutrition. The etiopathogenesis of obesity is multifaceted and may arise from several factors such as poor diet quality, nutrient deficiencies despite excess calorie consumption, genetics, and metabolic abnormalities affecting nutrient absorption and utilization. Moreover, a chronic low-grade inflammatory state resulting from excess adipose tissue, commonly observed in obesity, can further exacerbate malnutrition by altering nutrient metabolism and increasing metabolic demands. The dual burden of obesity and malnutrition poses significant risks, including immune dysfunction, delayed wound healing, anemia, metabolic disturbances, and deficiencies in micronutrients such as vitamin D, iron, magnesium, and zinc, among others. Malnutrition is often neglected or not given enough attention in individuals with obesity undergoing rapid weight loss through aggressive caloric restriction, pharmacological therapies, and/or surgical interventions. These factors often exacerbate vulnerability to nutrition deficiencies. We advocate for healthcare practitioners to prioritize nutrition assessment and initiate medical intervention strategies tailored to address both excessive caloric intake and insufficient consumption of essential nutrients. Raising awareness among healthcare professionals and the general population about the critical role of adequate nutrition in caring for patients with obesity is vital for mitigating the adverse health effects associated with malnutrition in this population.

Aims: The present study evaluated the effect of oral zinc supplementation on shortening hospital length of stay.

Methods: A systematic review was conducted for randomized control trials in patients who were hospitalized regardless of age and cause of admission. Studies were collected from PubMed, Web of Science, SCOPUS, and the Cochrane Library until July 2023. Results were compared between the zinc group and those who received a placebo and/or the standard therapy.

Results: Eight studies were qualified for our meta-analysis. Of the 1267 patients, 633 and 634 were in the zinc supplementation and control groups, respectively. The meta-analysis found that oral zinc supplementation group experienced a lower length of hospital stay than the control group (mean difference, -0.43 days; 95% confidence interval, -0.65 to -0.22; P < 0.0001; heterogeneity, I² = 20%).

Conclusion: The administration of oral zinc supplements was associated with a slightly reduced duration of hospital stay.

Most every new clinician practicing in nutrition support enters their practice environment with wide open eyes and a sense of curiosity as they encounter new patient and clinical experiences. As clinicians expand their expertise, they often identify challenges they are eager to address. Eagerness turns to passion as the desire to affect change grows. Malnutrition has sparked curiosity and interest in many, and, in some, it has become a passion. As a result, many major achievements have occurred both in the United States and globally that have the capability of moving the needle favorably to achieve better outcomes for our patients. This lecture will highlight how curiosity, eagerness, and passion have led to successes in addressing aspects of malnutrition. These successes offer the structure to continue our efforts to move the needle forward. Our patients deserve nothing more.

Background: Differences in definitions and operational diagnoses for sarcopenia create difficulties in understanding the epidemiology of the disease. We examined the prevalences of sarcopenia using the revised European Working Group on Sarcopenia in Older People (EWGSOP2) and the Sarcopenia Definitions and Outcomes Consortium (SDOC) consensuses and analyzed their level of agreement in patients receiving hemodialysis.

Methods: Data from the SARCopenia trajectories and associations with clinical outcomes in patients receiving hemodialysis (SARC-HD) multicenter study in Brazil were analyzed. Muscle strength was assessed using handgrip strength, muscle mass by calf circumference, and physical performance by the 4-m gait speed test. Sarcopenia was diagnosed according to both the EWGSOP2 (low muscle strength plus low muscle mass) and the SDOC (low muscle strength plus low physical performance). The Cohen kappa statistic was used to determine the level of agreement between the consensuses.

Results: 838 patients (57.8 ± 15.0 years; 61% men) from 19 dialysis units were included. We found similar prevalences of sarcopenia between the consensuses (EWGSOP2, n = 128, 15.3%; SDOC, n = 105, 12.5%) but with weak agreement (50 of 233 patients, 21.5%; κ = 0.34, 95% CI 0.25-0.43). Agreement was also weak within age categories (≥60 years, κ = 0.34; <60 years, κ = 0.15; both P < 0.001). Of the 51 patients diagnosed by the EWGSOP2 criterion as having severe sarcopenia, all but 1 (98.0%) met the SDOC criterion for sarcopenia (κ = 0.61, 95% CI 0.52-0.70). Low muscle strength was more frequently diagnosed using the SDOC than with the EWGSOP2 (52.3% vs 25.9%).

Conclusion: We found a weak agreement between the EWGSOP2 and SDOC consensuses for the diagnosis of sarcopenia in patients receiving hemodialysis. Although still weak, agreement was marginally better for older patients. These findings highlight the importance of a global and standardized conceptual diagnosis of sarcopenia.

Background: Collaboration between registered dietitians and gastroenterologists has not been evaluated in cystic fibrosis (CF). We surveyed registered dietitians and gastroenterologists regarding the current participation of gastroenterologists in CF centers and identified possible areas to enhance partnership between the two disciplines.

Methods: An anonymous online survey was distributed targeting registered dietitians and gastroenterologists involved in CF care through three international listservs (CF Nutrition, CF DIGEST, and PEDGI) over a 6-week period. SurveyMonkey was used, and informed consent was obtained.

Results: A total of 131 respondents participated in this survey, including 80 registered dietitians and 51 gastroenterologists (41 pediatric and 10 adult gastroenterologists). Most respondents (82%) were from the United States, and two-thirds had ≥5 years of experience in CF. A significant number of registered dietitians reported the nonavailability of gastroenterologists for collaboration and there was greater availability of gastroenterologists in pediatric centers. Barriers to interdisciplinary collaboration included lack of CF expertise and dedicated time among the gastroenterologists and difficulties in coordinating the gastroenterology clinics. More gastroenterologists than registered dietitians perceived that they worked collaboratively with the other discipline in various domains (clinical care, quality improvement, research, presentations, and publications). Both disciplines had mutual respect and interest to further the collaboration.

Conclusion: There is an increased need for gastroenterologist participation and collaboration (particularly in adult centers) in CF alongside registered dietitians to enhance comprehensive patient care. Future efforts should focus on training more gastroenterologists in CF and facilitating easier access to gastroenterologists for the CF population.

Information on the use of validated malnutrition risk screening tools in pediatric facilities to guide malnutrition identification, diagnosis, and treatment is scarce. Therefore, a survey of pediatric healthcare facilities and practitioners to ascertain malnutrition risk screening practices in North America was conducted. A pediatric nutrition screening practices survey was developed and sent to members of the American Society for Parenteral and Enteral Nutrition, the Council for Pediatric Nutrition Professionals and the Academy of Nutrition and Dietetics Pediatric Nutrition Practice Group. Respondents represented 113 pediatric hospitals in the United States and six in Canada, of which 94 were inpatient and 59 were outpatient. Nutrition risk screening was completed in 90% inpatient settings, and 63% used a validated screening tool. Nurses performed most malnutrition risk screens in the inpatient setting. Nutrition risk screening was reported in 51% of outpatient settings, with a validated screening tool being used in 53%. Measured anthropometrics were used in 78% of inpatient settings, whereas 45% used verbally reported anthropometrics. Measured anthropometrics were used in 97% outpatient settings. Nutrition risk screening was completed in the electronic health record in 80% inpatient settings and 81% outpatient settings. Electronic health record positive screen generated an automatic referral in 80% of inpatient and 45% of outpatient settings. In this sample of pediatric healthcare organizations, the results demonstrate variation in pediatric malnutrition risk screening in North America. These inconsistencies justify the need to standardize pediatric malnutrition risk screening using validated pediatric tools and allocate resources to perform screening.

Children with medical complexity (CMC) and children with chronic critical illness (CCI) represent growing populations with high healthcare use and dependence on specialized care, both in the hospital and community setting. Nutrition assessment and delivery represent critical components of addressing the short-term and long-term health needs for these populations across the care continuum. This article provides a framework and reviews existing literature for the assessment of nutrition status and subsequent delivery of nutrition prescriptions in CMC and children with CCI. The specific aims are to (1) describe the epidemiology of health services experience for CMC and children with CCI, with a focus on their nutrition outcomes; (2) detail how to assess their nutrition status and energy requirements; (3) review methods of delivery of the nutrient prescription; (4) introduce perioperative considerations; (5) highlight examples of special populations of CMC and children with CCI; and (6) propose future research initiatives to improve nutrition and overall outcomes for these populations.

Background: There exists a bidirectional relationship between tuberculosis (TB) and nutrition, wherein they mutually influence and interact causally. However, current guidance for providing nutrition support to individuals diagnosed with TB remains inadequate, leading to a significant gap in comprehensive patient care. This study aims to assess the nutrition status of patients with TB and endeavors to provide insights into early nutrition interventions for individuals vulnerable to TB-associated malnutrition.

Methods: Data from 2204 newly admitted patients at Beijing Chest Hospital in 2020 were collected, with 1735 patients with confirmed TB aged ≥18 years after exclusions. Patient data, encompassing diagnosis and results from routine blood tests and biochemical analyses conducted on the day after admission, were gathered using the electronic medical records system. Nutrition risk screening was conducted using the Nutritional Risk Screening 2002 (NRS 2002) tool, and questionnaire-based assessments were administered. Statistical analyses were performed using SPSS 17.0 software.

Results: Among 1735 patients with TB, the occurrence rate of nutrition risk was 74.58%. Factors such as age ≥65 years, sputum smear positivity for TB, and concurrent illnesses significantly increased the occurrence rate of nutrition risk. Nutrition risk among patients with TB exhibited negative correlations with parameters such as body weight, hemoglobin, and serum albumin level while showing positive correlations with white blood cell count and C-reactive protein, among others.

Conclusion: The occurrence rate of nutrition risk among patients with TB at Beijing Chest Hospital was notably high, particularly among older individuals, those with sputum smear positivity, and those with concurrent illnesses.
