AI Article Synopsis
- Pediatric patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) face risks related to their nutritional status, specifically body mass index (BMI), which affects transplantation success.
- A study analyzed BMI data from patients treated between 2003 and 2023 and found that underweight patients had significantly lower survival rates and higher complications compared to those with normal or higher BMI.
- The research emphasizes the need for regular nutritional assessment before and after transplant to improve outcomes, suggesting that BMI should be closely monitored to manage risks effectively.
Article Abstract
Background: Pediatric patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) face several risk factors influencing transplantation success, including nutritional status as measured by body mass index (BMI).
Methods: This study analyzed BMI data collected from patients transplanted between 2003 and 2023, and aimed to evaluate whether deviations from normal BMI are associated with poorer clinical outcomes. BMI levels assessed before and after first-line treatment and pre-transplantation were analyzed retrospectively to determine a correlation with survival and post-transplant complications.
Results: Underweight patients had significantly lower 12- and 36-month overall survival rates compared to normal-weight and overweight patients ( = 1.22 × 10 and = 8.88 × 10, respectively). Event-free survival was also lower for underweight patients at all time points. A higher pre-transplant BMI increases the risk of acute graft-versus-host disease (GVHD, = 0.00068). Otherwise, pre-transplant BMI was not significantly correlated with early TRCs and cGVHD. As secondary objectives, this study identified differences in BMI across primary disease groups, with solid tumor patients having the highest BMI and myelodysplastic syndrome patients having the lowest. BMI cut-offs were identified to predict or protect against serious outcomes, including delayed engraftment, TRCs, and acute and chronic GVHD.
Conclusions: This study highlights the importance of nutritional assessment and management in pediatric patients undergoing allo-HSCT to optimize post-transplant outcomes, as deviations from a normal BMI can significantly impact post-transplant health. These findings underscore the importance of integrating BMI assessment throughout the entire pre-HSCT therapeutic course to identify patients at higher risk for complications and to define more effective nutritional management strategies.

Reliable and sensitive testing of physical function is crucial for assessing the effects of treatment or exercise intervention in various patient populations. The present study investigated the test-retest reliability and sensitivity (smallest detectable difference: SDD) of selected physical performance tests commonly used in clinical rehabilitation, including tests of habitual and maximal walking speed, walking endurance capacity, handgrip strength (HGS), and lower limb muscle power (Sit-to-Stand (STS), stair climb) in adults with severe obesity meeting the criteria for bariatric surgery. Thirty-two adults (BMI 43.

Purpose Of The Review: Ultra-processed foods (UPFs) represent foods that have undergone substantial industrial processing, such as the addition of preservatives and various other ingredients, thereby making them more tasty, appealing and easy to consume. UPFs are often rich in sugars, saturated fats and salt, while they are low in essential nutrients.The aim of this review is to examine the relationship between the widespread consumption of UPFs and the development of obesity among children and adolescents.

Purpose Of Review: Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder with several causal pathways including impaired glucose tolerance, insulin resistance (IR), compensatory hyperinsulinemia and excess androgens (hyperandrogenism). This heterogeneous condition causes a range of reproductive, metabolic and psychological implications, the severity of which can differ between individuals depending on factors such as age, diet, ethnicity, genetics, medication, contraceptive use, adiposity, and Body Mass Index (BMI).
Recent Findings: Dietary interventions that focus on a low glycaemic index and glucose control are an efficient first-line dietary solution for the management of impaired glucose tolerance and IR, which subsequently improves weight management, quality of life and PCOS-related symptoms in individuals with this condition.
