Multimodal Nutritional and Sarcopenia Assessment for Risk Stratification in Lung Cancer Surgery

This prospective observational cohort study aims to evaluate the prognostic value of multimodal nutritional status and sarcopenia assessment in patients undergoing lung cancer surgery. Postoperative complications, mortality, and prolonged hospital stay remain major clinical concerns in thoracic surgery. Although malnutrition and sarcopenia are recognized as important determinants of surgical outcomes, their combined and multidimensional evaluation has not been sufficiently studied. Adult patients undergoing anatomical lung resection for primary lung cancer will be included. Nutritional status will be assessed using serum biomarkers, inflammatory indices, and validated clinical nutritional scores. Sarcopenia will be evaluated using computed tomography-based muscle mass and density measurements, as well as ultrasonographic muscle thickness. These parameters will be analyzed in relation to postoperative complications, intensive care unit (ICU) requirement, length of hospital stay, and mortality. Multivariable analyses will be performed to identify independent predictors, and a combined risk stratification model will be developed. This study aims to improve preoperative risk assessment and to support personalized perioperative management strategies, including identification of patients who may benefit from targeted nutritional optimization and prehabilitation.

Impact of Sleep Deprivation on Malnutrition in ICU (Intensive Care Unit) Patients

Study Design This study is a prospective cohort design conducted at Zhongshan Hospital affiliated with Fudan University. It will involve systematic assessments of sleep quality, nutritional status, and associated clinical outcomes in adult ICU patients over a defined observation period. Sample Size: An estimated 150 adult patients (≥18 years) will be recruited from the ICU. Assessments 1. Sleep Quality Assessment: 1. Polysomnography (PSG): Sleep quality and duration will be quantified using PSG, which records brain waves, blood oxygen levels, heart rate, and breathing, as well as eye and leg movements. This will provide a comprehensive picture of sleep architecture and disturbances. 2. Sleep Quality Index: In addition to PSG data, the Pittsburgh Sleep Quality Index (PSQI) will be administered to assess subjective sleep quality, sleep latency, duration, habitual sleep efficiency, sleep disturbances, and daytime dysfunction. 2\. Nutritional Status Evaluation: 1. Nutritional Risk Screening Tools: The Nutritional Risk Screening (NRS-2002) and the Malnutrition Universal Screening Tool (MUST) will be applied to assess nutritional risk and identify malnutrition. 2. Biochemical Assessment: Blood samples will be collected to measure biochemical indicators such as serum albumin, transferrin, prealbumin, and other relevant markers of nutritional status. 3. Anthropometric Measurements: Body mass index (BMI) and muscle mass assessments will be conducted using bioelectrical impedance analysis (BIA) or dual-energy X-ray absorptiometry (DEXA) to quantify body composition. 3\. Physiological Monitoring: 1. Continuous monitoring of vital signs, including heart rate, blood pressure, and respiratory rate, will be performed. 2. Assessment of immune function through laboratory tests, including white blood cell count and levels of inflammatory markers (C-reactive protein). 4\. Complications Tracking: 1\. Data on complications such as infections, delayed wound healing, and respiratory failure will be systematically recorded throughout the ICU stay. This study aims to elucidate the complex interplay between sleep deprivation and malnutrition in ICU patients. By identifying key associations and influencing factors, we hope to inform targeted clinical interventions that can improve patient care, recovery, and quality of life. The findings will serve as a foundation for future research exploring the intricate relationships between sleep and nutritional status in critical care settings.

Management of Undernutrition on Discharge From Hospital by Dieticians and Physical Activity Teachers at Home

The DENUTADOM study is a single-center feasibility study. It is an interventional research project involving human subjects (RIPH2), which will lead to a change in the care and treatment of adult patients diagnosed as suffering from moderate to severe undernutrition during hospitalization. The aim of this study was to assess patient compliance with a new undernutrition management program (diet and physical activity) at discharge from hospital. In this study, during hospitalization, patients may be included in the study if they meet the inclusion criteria. To this end, the physician will offer to participate in the study, and will provide the patient with an information document. If the patient agrees to take part, he or she will be included in the study after signing the consent form. Participation will last 3 months. On inclusion, after seeing the physician, an adapted physical activity teacher (EAPA) and a hospital dietician will assess the patient's physical capacities and dietary needs, in order to draw up an adapted physical and dietary program. The CRA will assess the patient's quality of life using a questionnaire. When the patient is discharged, he will be given a notebook in which to keep track of appointments with healthcare professionals (GP, private dietician, EAPA). Patients are also asked to keep a record of their non-protocol care appointments and participation in physical activities. After hospitalization, the patient will have to follow a multi-professional program: dietetic by a private dietician (at D3-J5, at 3 weeks and then at 6 weeks), medical by the general practitioner (at 1 month), and adapted physical activity by the EAPA (during 3 months). At three months, the patient will be seen again by the hospital's health professionals. The investigating physician will reassess nutritional status, and the EAPA will reassess physical capacity. The patient will be asked to return his diary so that data can be collected. They will also be given a quality of life and satisfaction questionnaire to complete. When all patients have completed their follow-up, a satisfaction questionnaire will be sent to each healthcare professional. Currently, as part of standard care, , dietetics and physical rehabilitation are not reimbursed. As a result, although recommended, patients rarely benefit from a dietetic consultation and adapted physical activity follow-up following a diagnosis of undernutrition. We therefore hypothesize that early cooperative outpatient care, involving general practitioners, private dieticians and adapted physical activity teachers (EAPA), for adult patients diagnosed as moderately or severely malnourished during hospitalization will optimize the management of these patients.

PSYCHOSOCIAL STIMULATIONS AND TREATMENT OUTCOME OF SEVERE ACUTE MALNOURISHED CHILDREN

A playroom and a playground are already part of the stabilization unit and are furnished with basic facilities for engaging the SAM children in play-based motor, language, and personal-social activities. The severely acute malnourished children in the intervention group will be sent to a development pediatrician who will do a developmental assessment of the child and stimulation. A sensory therapist, an occupational therapist, and a physiotherapist will also be available for sessions.
