Impact of Oral Phosphorus Supplements on the 6-month Change in FGF23 Levels in Anorexic Adolescents Suffering From Undernutrition.

Fibroblast growth factor 23 (FGF23) is a recently discovered phosphaturic hormone produced by osteocytes. It is involved in phosphate-calcium metabolism (via its phosphaturic action and inhibition of 1,25-OH vitamin D). There are no published studies on the role of FGF23 in undernourished anorexic adolescents taking oral phosphorus supplements.

Preoperative Immunonutrition in Patients With Bone and Soft Tissue Sarcomas

This study will evaluate whether a short nutritional intervention before surgery can improve recovery in patients with bone and soft tissue sarcomas. Patients with these tumors often have a higher risk of poor nutrition and loss of muscle mass. These problems may increase the risk of complications after major orthopedic surgery. Participants will be randomly assigned to one of two groups. One group will receive a special oral nutritional supplement twice daily before surgery, in addition to standard care. The other group will receive standard care without the preoperative nutritional supplement. The main aim of the study is to compare the rate of clinically relevant postoperative complications within 30 days after surgery. The study will also evaluate changes in muscle mass on CT scans, blood markers of nutrition and inflammation, nutritional risk, functional status, length of hospital stay, and tolerance of the nutritional supplement.

The goal of this observational study is to learn whether preoperative oral nutrition support improves clinical outcomes in elderly patients with femur fractures who have a high frailty index. The main questions it aims to answer are: * Does preoperative nutrition support improve hemodynamic stability during and after surgery? * Does it reduce postoperative complications, mortality, and length of hospital stay? Researchers will compare patients who receive preoperative oral nutrition support with those who follow routine nutrition. Participants will: * Receive routine medical care with or without nutrition support * Have their hemodynamic values, complications, and outcomes recorded during hospitalization * Be followed at 30 and 90 days after surgery for complications and mortality.

Sustainable Eating Pattern to Limit Malnutrition in Older Adults

The SENIOR STUDY is aimed at improving the condition of older adults and malnutrition management in and out Italian hospital settings, since malnutrition is highly prevalent, clinically relevant and potentially treatable condition. This study consist of two phases: an initial cross-sectional phase and a secondary nutritional intervention phase (RCT). The SENIOR CROSS-SECTIONAL study aims to map malnutrition status in accordance with the most recent GLIM criteria and investigate the association between malnutrition and anthropometric, demographic and socioeconomic, and lifestyle factors. In addition, sarcopenia will be diagnosed (EWGSOP2 consensus criteria) and blood markers will be measured. Malnutrition in Italian hospital setting is highly prevalent but the current malnutrition data prevalence and the general characteristics of older adults are not updated. Thus, it is expected to find a high malnutrition prevalence and an inadequate nutritional status.

Microbiome and Malnutrition in Pregnancy

This study is being conducted to investigate how a mother's nutritional status and her gut microbiome during pregnancy contribute to the birth outcomes and health of her baby. The gut microbiome is the totality of microorganisms (e.g. bacteria, viruses, fungi) living in the gastrointestinal tract. This study will focus on pregnant women, 28 years and younger living in the Toronto and greater Toronto area. The focus is on younger women due to their vulnerability to undernutrition. Pregnant participants, and upon delivery, their newborns will be followed throughout pregnancy and for a year afterwards. Throughout this period, the investigators will collect stool samples, rectal swabs, blood samples, health assessments, nutritional and dietary assessments and birth/ labour details. The goal is to define the relationship between a mother's nutritional status and her microbiome dynamics during pregnancy and how they contribute to the birth outcomes and growth of her newborn. With the hypothesis that alterations of the microbiota in the maternal gut (dysbiosis) exacerbated by nutritional status or pathogen exposure during pregnancy, impacts weight gain because of impaired nutrient absorption, leading to corresponding negative birth outcomes.

Extending the Validation of SCREEN to Persons Living With Dementia or in Retirement Homes

Older adults (≥ 55 years) who do not eat enough nutritious food are at risk of malnutrition. Malnutrition can lead to frailty, hospitalization, poor quality of life, and death. SCREEN (Seniors in the Community Risk Evaluation for Eating and Nutrition) is the leading nutrition risk screening tool for cognitively well older adults living in the community. The purpose of this study is to determine if SCREEN can be used to find nutrition risk among older adults diagnosed with mild cognitive impairment or dementia (i.e., MCI-D) or those with a MoCA \< 26 living in the community and persons living in retirement homes. SCREEN and other nutrition and health measures will be completed in 600 older adults (300 living in retirement homes with or without MCI-D, and 300 living with MCI-D in the community). SCREEN will be completed twice to determine reliability, and persons with MCI-D will have their results compared to those of a caregiver who completes it on their behalf. A dietitian's assessment and rating of nutrition risk will be used as the gold-standard to determine validity.

To compare the detection rates of undernutrition between a range of nutritional screening tools, physiological measures and assessment tools amongst patients with different IBD phenotypes 2. To correlate nutritional status, nutritional biomarkers and body composition with clinical outcomes in patients with IBD treated with advanced medical therapy or surgery 3. To determine a potential relationship between radiological muscle mass measurements and clinical outcomes in patients with IBD treated with advanced medical therapy or surgery Participants will undergo an assessment at pre-treatment baseline and then again at their scheduled follow-up. This is a non-interventional study and participants will not be required to have any invasive tests or hospital visits beyond that of standard clinical care.

Standard Duodenal Switch vs. Single Anastomosis Duodeno-Ileostomy Duodenal Switch

The aim of the Torsby I Trial is to identify differences and similarities between a standard duodenal switch (DS) and a single-anastomosis duodeno-ileostomy (SADI) regarding effect on weight, comorbidities and malnutrition.

The Effect of Intradialytic Parenteral Nutrition on Nutritional Status and Quality of Life in Hemodialysis Patients

Protein-energy wasting (PEW), a hypercatabolic state characterized by loss of muscle mass and fuel reserves, is highly prevalent in hemodialysis patients. Nutritional status and body composition are closely linked to morbidity, mortality and quality of life. Lean tissue mass (LTM) appears to be the best read-out for the association between nutritional status and outcomes. Intradialytic parenteral nutrition (IDPN) is occasionally used with the aim to reduce loss of LTM, but its efficacy has not been established. The goal of this study is to study the effect of IDPN on changes in LTM in hemodialysis patients.

This study aims to describe the incidence of depression and its complications like malnutrition in patients followed for surgical site infection to allow their best management and prevention

Nutritional Prehabilitation to Improve Cancer Outcomes (N-PICO)

Brief Summary The goal of this clinical trial is to evaluate the acceptability and adherence of low- and high-intensity remote nutritional interventions for cancer patients in rural and urban areas, specifically focusing on those with invasive cancer who are about to start treatment. The main question\[s\] it aims to answer are: Can low- and high-intensity remote nutritional interventions improve adherence to cancer treatment and quality of life? What is the impact of nutritional support on treatment delays, unplanned healthcare utilization, and dietary modifications? Researchers will compare the low-intensity arm (initial nutritional consultation plus written materials) to the high-intensity arm (1-hour consultation, monthly follow-ups, and written materials) to see if higher intensity interventions lead to better outcomes in terms of adherence, quality of life, and healthcare utilization. Participants will: Receive either a low- or high-intensity nutritional consultation. Complete surveys assessing quality of life, dietary habits, treatment delays, and unplanned healthcare use. Be asked to participate in monthly follow-up consultations (for the high-intensity group) to track progress and provide additional support.

Nutritional Management of the Patient With Type 2 Diabetes at Nutritional Risk or With Malnutrition in Clinical Practice

The objective of this observational study is to characterize the patient profile and nutritional treatment patterns of individuals with type 2 diabetes (T2D) or drug-induced diabetes who present with malnutrition, or are at risk of it, and who are prescribed a diabetes-specific oral nutritional supplement (ONS) that is high in calories and protein and contains soluble fiber. Participants will complete a series of questionnaires during visits 1 and 3.

Child Health, Nutrition and Microbiome Development

Childhood malnutrition is a global public health issue with devastating consequences on the health, well-being, and psychosocial development of children. Emerging evidence suggests that malnourished children have immature gut microbiota compared to age-matched healthy controls and it does not repair even after nutritional interventions. The present study aims to characterize how the gut microbiome develops during the first two years of life in children residing in malnutrition endemic areas of Khyber Pakhtunkhwa, the region with the highest prevalence of childhood malnutrition in Pakistan and the region.

Nutrition in Patient With Critical Limb Ischemia

A prospective pilot study examining nutritional supplements among vascular surgery patients with Critical Limb Ischemia (CLI). CLI patients have a high rate of malnutrition and has the potential to benefit greatly from nutritional intervention. The investigators plan to evaluate nutrition and functional status of patients by assessing objective lab values and the use of the hand grip strength test. Providing perioperative nutritional supplements to patients has potentially improved their nutritional status, which in turn may improve the patient's clinical status after surgery.

Early Nutritional Intervention in Patients With Cancer

The goal of this intervention study is to study the effect of nutritional interventions in patients with cancer receiving palliative chemotherapy. The main question it aims to answer is: Does early nutritional interventions affect body weight, quality of life, survival, muscle mass, performance status, physical function, nutritional risk and treatment tolerance in patients with cancer receiving palliative chemotherapy? Researchers will compare patients receiving the intervention to a historical control cohort following current clinical practice.

Tailored Stapled SADI-S: Initial Report and Preliminary Results

Obesity is a serious health problem worldwide and can lead to many diseases such as diabetes, high blood pressure, heart disease, and sleep apnea. When lifestyle changes and medications are not enough, metabolic and bariatric surgery (MBS) is currently the most effective and long-lasting treatment option. This study focuses on one of the newer types of bariatric surgery called Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S). This procedure combines two parts: Sleeve gastrectomy, which reduces the size of the stomach so the patient feels full after eating a small amount. Duodeno-ileal bypass, which shortens the path food takes through the small intestine to reduce calorie absorption. Our hospital's surgical team is studying a tailored version of this operation, where the length of the bypassed intestine is adjusted to each patient's anatomy. We believe this personalized approach may improve weight loss results while lowering the risk of vitamin and nutrient deficiencies. The study will include 40 adult patients with obesity who are undergoing SADI-S surgery, either as their first weight loss operation or as a revision surgery after an earlier sleeve gastrectomy. During the operation, surgeons will measure the total length of each patient's small intestine and use a formula to decide how much of it should be bypassed. The duodeno-ileal connection will be made using a stapled technique, which is expected to be safe and efficient. After surgery, patients will be followed regularly at 1, 3, 6, 9, and 12 months, and then once per year. At each visit, the study team will monitor weight loss, body mass index (BMI), resolution of diabetes and other obesity-related conditions, nutritional status (including vitamins and minerals), and any side effects such as diarrhea, reflux, or nutritional problems. The goal of this study is to learn whether this tailored SADI-S technique can provide strong, sustained weight loss and health improvement with fewer long-term complications. The results will help improve surgical planning for future patients by showing whether measuring and customizing the bypass length is safer and more effective than using a fixed length. All data collected will be kept confidential. Patients' participation in the study will not change their regular care or follow-up, and they can withdraw at any time without affecting their treatment.
