Osteoporosis and Sarcopenia Prevention in Middle-Aged Population

This initiative is designed to yield substantial and multi-level benefits for the Hong Kong community by pioneering a transformative model of preventive healthcare. It represents the largest randomized controlled trial for osteoporosis and sarcopenia prevention in the region, adopting a comprehensive approach to fracture prevention through innovative fitness, lifestyle, and digital strategies. The study's primary objective is to evaluate the efficacy of preventing fractures, osteoporosis, and sarcopenia through an incentivized program of fitness and lifestyle modifications in adults aged 40-60. The secondary objectives include: (1) to validate the use of simple, low-cost measures (grip strength and InBody body composition analysis) as reliable proxy indicators for osteoporosis and sarcopenia risk relative to the gold-standard DEXA scan; (2) to develop a formal, standardized clinical protocol for early detection and prevention, including specified DEXA anatomical measurement sites, for use by healthcare professionals in primary and community care settings; (3) to assess changes in exercise behavior, musculoskeletal health, physical function, health literacy, and participant engagement with the digital (AI chatbot) support system; (4) to analyze the cost-effectiveness of the intervention compared to standard care or pharmacological treatment, including an assessment of healthcare utilization and Quality-Adjusted Life Years (QALYs). After baseline screening and consent, participants are randomly assigned to one of two groups (1:1 ratio) with intention-to-treat principles. The Control Group will receive passive, static support. This involves participating in one initial FUN Day, receiving standard exercise videos, using a passive chatbot for data reporting, undergoing start and end DEXA scans (which require a co-payment), completing a 3-month assessment, and receiving souvenirs at the study start and end. Meanwhile, the Intervention Group will receive active, dynamic support designed to build and reinforce healthy habits. This involves participating in the initial FUN Day, a reinforcement FUN Day at 2 months, nine mandatory structured exercise touchpoints, using an active chatbot with reminders, feedback, and gamification, undergoing start and end DEXA scans (which require a co-payment), completing a 3-month assessment, and receiving ongoing incentives and souvenirs at multiple points. Therefore, researchers will compare between the control and intervention groups to see if intervention can prevent osteoporosis and sarcopenia at a population level. All participants will undergo a series of assessments at specific timepoints. This includes two DEXA scans (at the study start and in the fourth year, requiring a participant co-payment), InBody composition analysis, and physical health assessments (e.g., grip strength, balance, cardiovascular fitness). These assessments will be performed at baseline (during the first FUN Day), 3 months, 12 months, 24 months, and 36 months. A long-term follow-up will continue for up to 10 years to monitor adverse health events such as falls and fractures. Participants will also complete questionnaires via an AI chatbot at baseline, 3 months, and annually during follow-up. The collected data will encompass health literacy (e.g., osteoporosis/sarcopenia knowledge scores), digital engagement (e.g., chatbot responsiveness), and economic outcomes (e.g., incremental cost per Quality-Adjusted Life Year \[QALY\] gained). Data analysis will employ appropriate statistical methods to compare outcomes between the control and intervention groups across all assessments and timepoints.

Effects of Lower Body EMS Training in Postmenopausal Women

This study evaluates the effects of a 8-week lower body Electrical Muscle Stimulation (EMS) training program on body composition, muscle function, and arteriosclerosis markers in postmenopausal women. Menopause is associated with a rapid decline in estrogen, which increases the risk of sarcopenia (muscle loss) and arterial stiffness (cardiovascular disease). While resistance training is effective for these conditions, participation rates among postmenopausal women are often low. This study investigates whether applying EMS during lower body resistance exercises provides superior benefits compared to resistance training alone or no intervention. Participants will be randomized into three groups: 1. Lower-body EMS combined with Resistance Training Group 2. Resistance Training Only Group 3. Control Group (No intervention) The study aims to verify the efficacy of EMS as a time-efficient and effective alternative exercise modality for improving vascular and musculoskeletal health in this population.

Sarcopenia Risk Screening in Patients With Gastrointestinal Cancer Using SARC-F

Sarcopenia is a syndrome characterized by progressive loss of skeletal muscle mass and strength and is associated with worse outcomes in cancer patients. It can negatively affect prognosis, increase postoperative complications, reduce tolerance to systemic therapy, and impair quality of life. Sarcopenia may be present even in patients with preserved nutritional status or overweight. This study evaluated the proportion of patients with gastrointestinal cancer who were at risk of sarcopenia, as assessed by the SARC-F screening questionnaire, before initiation of systemic treatment and during treatment. Patients with a positive screening result could be referred for further nutritional evaluation and assessment of sarcopenia severity using anthropometric measurements and DXA, according to standard clinical practice.

Effectiveness of Combined GLP-1 Receptor Agonist Therapy and Structured Exercise on Skeletal Muscle Morphology, Quality, and Physical Function in Overweight and Obese Individuals

This randomized controlled trial aims to investigate the effects of a 24-week home-based progressive resistance exercise program combined with tirzepatide treatment on skeletal muscle mass, muscle quality, and functional capacity in overweight and obese individuals. A total of 108 participants initiating tirzepatide therapy will be randomized to either exercise plus pharmacotherapy or pharmacotherapy alone. The primary outcome is change in thigh muscle thickness and echo intensity assessed by ultrasonography.

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.

Muscle Ultrasound for Sarcopenia Assessment in Kidney Transplant Recipients

This is a single-center prospective observational study designed to evaluate the effectiveness of multimodal muscle ultrasound for the assessment of sarcopenia in kidney transplant recipients. Adult patients undergoing kidney transplantation will undergo both muscle ultrasound and bioelectrical impedance analysis (BIA) at predefined time points before and after transplantation. The primary objective is to evaluate the diagnostic performance of muscle ultrasound for sarcopenia assessment, including its correlation and agreement with BIA-derived skeletal muscle index (BIA-SMI), as well as its diagnostic accuracy. Secondary objectives include describing the longitudinal changes in sarcopenia prevalence and muscle-related parameters from the pre-transplant period to 1 year after transplantation. The study aims to provide evidence for a convenient, noninvasive, radiation-free, and reliable method for sarcopenia assessment in kidney transplant recipients.

The Efficacy of Aerobic Exercise Training on ANS and Endothelial Function in Compensated Cirrhosis

The goal of this randomized controlled trial is to investigate whether a 16-week structured aerobic exercise program combined with nutritional consultation can improve autonomic and endothelial function in patients with compensated cirrhosis. Study Design: This assessor-blinded, parallel-group randomized controlled trial will be conducted at King Chulalongkorn Memorial Hospital, Bangkok, Thailand. Fifty adults with compensated (Child-Pugh class A) cirrhosis will be recruited during routine hepatology clinic visits. Eligible participants are aged 45-75 years, have a sedentary lifestyle (\<150 minutes of moderate or \<75 minutes of vigorous physical activity per week), and have abstained from alcohol for at least six months. Exclusion criteria include active or recently treated hepatocellular carcinoma (within three months), severe portal hypertension complications (untreated large varices, prior variceal bleeding, or severe gastropathy), transjugular intrahepatic portosystemic shunt (TIPS), unstable cardiac disease, orthopedic limitations, morbid obesity (BMI \>35 kg/m²), or current use of alpha- or beta-blockers that affect autonomic function. Intervention: Participants will be randomly assigned to either the intervention or control group. Both groups will receive nutritional consultation and individualized dietary guidance at baseline, week 8, and week 16. Nutritional goals are set at 35 kcal/kg/day and 1.2 g/kg/day of protein intake. If targets are unmet, the dietitian will provide individualized recommendations to support adequate intake. The intervention group will participate in a 16-week aerobic exercise program consisting of brisk walking at moderate intensity (50-70% of maximal heart rate), totaling 150 minutes per week. The program includes two phases: * Phase 1 (Weeks 1-4): Combined hospital-based (1 session per week) and home-based exercise under physical therapist supervision, with gradual intensity titration. * Phase 2 (Weeks 5-16): Fully home-based exercise following prescribed intensity and frequency, with weekly follow-up via telephone or messaging to monitor adherence, safety, and exercise log completion. The control group will maintain their usual physical activity levels while receiving the same schedule of nutritional consultations and weekly follow-up for monitoring compliance and adverse events. Outcomes: Primary outcomes include changes in autonomic and endothelial function after 16 weeks. * Autonomic function will be assessed using the Ewing autonomic battery test (HR response to standing, deep breathing, and Valsalva maneuver; BP response to posture and sustained handgrip) and heart rate variability (HRV) indices (SDNN, RMSSD, LF/HF ratio). * Endothelial function will be evaluated using flow-mediated dilation (FMD) of the brachial artery, analyzed via Cardiovascular Suite™ software to assess nitric oxide-dependent vasodilation. Secondary outcomes include: 1. Splanchnic hemodynamics: Changes in celiac and superior mesenteric artery (SMA) blood flow measured via mesenteric Doppler ultrasound (Vivid IQ, GE Healthcare). Time-averaged mean velocity (TAMV), vessel diameter, and blood flow will be recorded at baseline and post-intervention. 2. Sarcopenia-related measures: Muscle mass (DEXA, BIA), muscle strength (handgrip dynamometry), and physical performance (6-minute walk test). 3. Laboratory outcomes: Serum ammonia, liver function tests, fasting glucose, albumin, renal function, and coagulation profile. 4. Correlative analyses: Associations between (a) muscle mass and serum ammonia, and (b) muscle mass and autonomic parameters (e.g., HRV indices).

BCW-Based Resistance Training for Community-Dwelling Sarcopenia Patients

The purpose of this randomized controlled trial is to evaluate the effects of a Behavior Change Wheel (BCW)-based resistance exercise program on muscle health, physical performance, and exercise adherence in community-dwelling older adults with sarcopenia. Participants will be randomly assigned to either an experimental group or a waitlist control group. The experimental group will receive a 12-week BCW-based resistance exercise intervention (twice a week) immediately. The waitlist control group will maintain their usual routine for the first 3 months for comparison, and will then cross over to receive the identical 12-week intervention. The study aims to provide an effective and ethical exercise management strategy for sarcopenic patients.

Preoperative Prehabilitation for Sarcopenic Patients Prior to Pancreatic Surgery for Cancer

Major digestive surgery is associated with a significant rate of postoperative complications. To improve postoperative outcome, efforts are focused on postoperative course leading to the concept of rehabilitation. However, the rehabilitation concept does not allow to improve muscular and functional reserves at the time of surgery. Sarcopenia is a condition characterized by loss of skeletal muscle mass and function. Also, the prevalence of sarcopenia in patients with cancer is high and has a prevalence of around 25% in patients with pancreatic cancer, with a considerable impact on postoperative and survival outcomes. The hypothesis is the preoperative management of sarcopenia by a rehabilitation program could improve patients' operative outcomes by reducing the rate of postoperative complications.

MyokinE100 System: Closed Loop Electrical Muscle Stimulation to Mitigate ICU Acquired Weakness in Medical ICU Patients

The goal of this clinical trial is to learn if a new medical device that sends electrical signals to the thigh muscles is safe and easy to use for people in the ICU (Intensive Care Unit) who are at risk of losing muscle strength. It will also explore whether this treatment can help slow down muscle weakening. The main questions this study aims to answer are: * Do participants develop medical problems when receiving electrical muscle stimulation in the ICU? * Is electrical muscle stimulation a practical way to help reduce muscle weakness in critically ill patients? Researchers will compare the control group (standard of care) to the intervention group (standard of care plus 60-minute sessions of electrical muscle stimulation daily during the ICU stay) to see if the device is safe and easy to use. Participants will: * Receive either standard of care or standard of care plus electrical muscle stimulation of the thigh muscles * Have their muscle strength checked during the study * Complete a survey three months after ICU discharge to check on their recovery

Evaluation of Safety and Efficacy of a Digital Therapeutic Device to Improve Strength in Sarcopenia (Sarc-DTx)

This clinical trial aims to demonstrate that the use of a digital therapeutic device (exoDTx) in patients with sarcopenia is superior to self-exercise in terms of muscle strength improvement and safety.

Effect of Sarcopenia and Frailty on Rocuronium Pharmacodynamics in Geriatric Patients

This prospective observational study aims to evaluate whether sarcopenia and frailty affect the pharmacodynamic profile of rocuronium in geriatric patients undergoing elective surgery under general anesthesia.

Assessment of in Vivo Skeletal Muscle Viscoelasticity (ARFI Imaging) With Aging and Cancer

Sarcopenia is known to be associated with loss in muscle mass that results from a reduced number of muscle fibres, an atrophy of remaining muscle fibres, and an increased infiltration of non-contractile tissue (collagen, fat). Accentuated by cancer and treatments, sarcopenia impairs muscle function resulting in a higher risk of physical disability and death. The commonly used test for sarcopenia screening consists in a DEXA (Dual energy X-ray absorptiometry) scan. However, this test can't provide structural muscle information. In contrast, the mechanical properties of muscle tissue can be explored using an acoustic radiation force impulse (ARFI). The question remains whether muscle sonoelastography using ARFI imaging could be helpful for sarcopenia screening. For this, volunteers will be recruited in three groups: ≤ 30 years (Gr A) and ≥ 70years, both without any serious chronic disease, and patients ≥ 70 years presenting curative cares for cancer (Gr C). The volunteers belonging to the groups A and B will be followed during one day. The patients included in the group C will be followed during 6 months. For this latter group; the first visit (t0) will take place before treatment and the second visit will take place 6 months later (t6months) Volunteers will have clinical examinations (weight, stature, BMI, performance status/ ECOG) and will be evaluated on their nutritional status (MNA-SF, 24h dietary recall) and physical capacities (IPAQ, SPPB, lower limb muscle strength, 6-min walk test, QLQ-C30 items relative to the fatigue symptom).

Effects of Aquatic Exercise in Older Adults With Sarcopenia:A Randomized Trial

Sarcopenia is a geriatric syndrome characterized by age-related loss of skeletal muscle mass, strength, and physical performance, leading to increased risk of falls, functional decline, and reduced quality of life. Exercise interventions, particularly resistance training, are effective in managing sarcopenia; however, land-based exercises may be challenging for older adults due to balance impairments, joint problems, and fear of falling. Pool-based exercise programs may offer a safe and feasible alternative, as water buoyancy reduces joint loading while providing resistance to support muscle strengthening. Despite these potential benefits, evidence regarding the effects of aquatic exercise in individuals with sarcopenia remains limited, especially in Türkiye. This study aims to evaluate the effects of a 6-week supervised pool-based exercise program on muscle strength, muscle morphology, physical performance, mood, and quality of life in individuals aged 65 years and older with sarcopenia. Sarcopenia will be identified using the Sonographic Thigh Adjustment Ratio (STAR), based on ultrasound measurements of anterior thigh muscle thickness. In addition, appendicular skeletal muscle mass will be assessed using bioelectrical impedance analysis (ASM/height²). Outcome measures will include ultrasound-based muscle thickness, STAR, muscle strength, functional performance tests, depressive symptoms, and health-related quality of life. Assessments will be performed at baseline, immediately after the intervention, and at 1-month follow-up.

CARTIZ Registry: Cartilage, Arthropathy and Imaging Under Tirzepatide in Zone-stratified Cohorts - A Four-Institute Mexican Observational Registry

CARTIZ is a prospective observational clinical registry of adults in Mexico receiving tirzepatide (a dual GLP-1/GIP receptor agonist) under an independent clinical indication - typically type 2 diabetes, insulin resistance, obesity, renal protection, metabolic hypertension, or associated off-label metabolic use. The registry is entirely observational: CARTIZ does not initiate, modify, interrupt, or supply tirzepatide, and does not dictate dose, route, or duration. All pharmacological exposure decisions are made by the treating physician independently of study participation. The registry is operationalized through a four-institute architecture integrating three Mexican National Institutes of Health and one national imaging laboratory. Core 1 (Knee Cartilage Imaging, Ci3M UAM-Iztapalapa) performs bilateral 3T MRI with quantitative T2 mapping at Week 0 and Week 52. Core 2 (Cardiac Imaging, Instituto Nacional de Cardiología Ignacio Chávez) performs non-contrast cardiac computed tomography for radiomic phenotyping of epicardial adipose tissue at Week 0 and Week 52 under cardiovascular Co-Principal Investigator Dr. Erick Alexánderson Rosas. Core 3 (HLA Typing, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Transplant Department) performs Class I and Class II HLA typing by PCR-SSO Reverse Luminex. Core 4 (Body Composition, Universidad La Salle México) performs multi-frequency bioelectrical impedance analysis (seca mBCA) at six longitudinal timepoints capturing visceral adipose tissue trajectory, phase-angle trajectory, appendicular skeletal muscle mass, and hydration ratios at zero marginal cost. The registry enrolls n=30 patients across three clinical sites with identical protocol (IMSS Clínica Río Magdalena, INCMNSZ outpatient clinic, and a private practice site in Mexico City), generating 60 evaluable knees and 30 paired cardiac CT studies. The primary co-endpoints address a mechanistic question no other tirzepatide study is positioned to answer: whether the articular response to tirzepatide in inflammatory arthropathy precedes and mechanistically precedes weight loss, through formal mediation analysis of Week-4 ACR20 response via high-sensitivity C-reactive protein, SERPINB2, and dipeptidyl peptidase-4 activity, restricted to the Mechanistic Analysis Set of patients with tirzepatide exposure ≤16 weeks at Week 0 and delta-BMI \<1.0 kg/m² through Week 4. A prespecified Surgical Tissue Subcohort is declared at initial registration to establish public scientific priority on direct human epicardial adipose tissue transcriptomic characterization under dual GIP/GLP-1 receptor agonism. Subcohort participants who undergo clinically indicated cardiac surgery at INCar during follow-up (coronary artery bypass grafting, valve replacement, or combined procedures) are invited to provide specific additional informed consent for collection of epicardial adipose tissue fragments routinely excised during operative access and otherwise discarded as surgical waste. Operational launch is contingent on separate INCar tissue-specific approvals and will proceed via PRS record amendment when ready

Magnesium Supplementation as a Nutritional Intervention in Sarcopenia

Sarcopenia is a progressive condition common in older adults and is characterized by loss of muscle strength, muscle mass, and physical performance. It is associated with an increased risk of falls, disability, reduced independence, and poorer quality of life. Nutritional interventions are recommended as part of sarcopenia management; however, evidence regarding the role of specific micronutrients remains limited. Magnesium is an essential mineral involved in muscle contraction, neuromuscular function, energy production, and inflammation regulation. Low magnesium status is frequent in older adults and may contribute to muscle impairment and physical decline. This study aims to evaluate the effects of magnesium supplementation on muscle strength, muscle mass, and physical performance in older adults with sarcopenia living in the eastern Algarve region of Portugal. In addition, the study will assess the prevalence of low magnesium status and sarcopenia in this population. The study will be conducted in two phases. In the first, observational phase, community-dwelling adults aged 70 years or older will be assessed for sarcopenia according to established diagnostic criteria. Blood samples will be collected to measure serum and erythrocyte magnesium levels and C-reactive protein as an inflammatory marker. Participants diagnosed with sarcopenia and presenting low magnesium levels will be eligible for the second phase. In the second phase, eligible participants will be randomly assigned to receive either oral magnesium supplementation (400 mg/day of magnesium citrate) or a placebo for 12 weeks, in a double-blind and controlled design. After the intervention period, participants will be reassessed for muscle strength, muscle mass, physical performance, magnesium status, and inflammation. The results of this study are expected to clarify the role of magnesium supplementation as a nutritional strategy in sarcopenia. Findings may contribute to improving nutritional recommendations and supporting interventions aimed at preserving muscle health, physical function, and quality of life in older adults.

The Effect of Volunteer-Engaged Lifestyle Optimisation Via ICOPE on Sarcopenia in Older Adults (VELO-S)

Sarcopenia prevention and management are highly prioritised goals in the Healthy Ageing agenda. The study aims to: 1) evaluate the effects of the digital-enhanced, volunteer-engaged collaborative care pathway to improve sarcopenia, reduce fall risk, and increase health-related quality of life (HRQL) among community-dwelling older adults with risk of, or diagnosed with, sarcopenia; 2) evaluate whether the volunteers who received health coach capacity training and supported the intervention experienced health benefits across time; 3) explore the engagement experiences and perceived effects of elderly participants with sarcopenia during the program; 4) evaluate the intervention implementation process and effects from the perspectives of social care workers.

Routine Validation and Reproducibility Testing of Laboratory Assays and Research Techniques Used for Endocrine, Cardiometabolic, and Musculoskeletal Disorder Research (VALD)

The purpose of this research study is to validate (check the accuracy of) laboratory assays, intravenous catheter insertion, and equipment or devices and their reproducibility, which is necessary to perform high quality research on chronic diseases, nutrition, and metabolism (the process by which a substance is handled in the body) at the University of Missouri. As technology changes and uses new testing methods, it is necessary to compare results from old tests, equipment and devices and new tests, equipment, or devices and the reproducibility of these measurements to make sure the results are accurate. Reproducibility means performing the same test more than once to see if the same results can be achieved each time. This study will look at the validation and reproducibility of tests and laboratory assays in participants who are healthy or affected by relevant endocrine, cardiometabolic, and musculoskeletal disorders.

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.

Ursolic Acid-Standardized Apple Pomace Supplementation for Muscle Strength and Physical Performance in Older Adults With Mild Sarcopenia: A Randomized, Double-Blind, Placebo-Controlled Trial

Sarcopenia is an age-related condition characterized by loss of muscle strength and physical performance, leading to increased risk of falls and disability. This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the effects of ursolic acid-standardized apple pomace supplementation on muscle strength and physical performance in older adults with mild sarcopenia. Participants will be randomly assigned to receive either 200 mg/day, 400 mg/day of the supplement, or placebo for 12 weeks. The primary outcome is change in handgrip strength, with additional assessments of physical performance, body composition, fatigue, and quality of life. The study will also evaluate the safety and tolerability of the intervention.

Effect of Protein, Mobility Therapy and Electric Stimulation on Recovery in Older ICU Survivors

Older ICU survivors with ICU acquired weakness (ICUAW) are malnourished, sarcopenic, and functionally debilitated as a consequence of the high burden of comorbidities common in the elderly. To address the sequalae of critical illnesses, the investigators will perform a trial incorporating an intervention that combines mobility-based physical rehabilitation (MRP), high protein supplementation (HPRO), and neuromuscular electric stimulation (NMES). The investigators will then assess both clinical and functional outcomes and determine the relationship of disability with systemic inflammation.

Prevalence of Sarcopenia and Its Associated Factors in Patients With Knee Osteoarthritis in a Tertiary Care Hospital in Upper Egypt

Osteoarthritis (OA) and sarcopenia are two highly prevalent, interconnected geriatric syndromes that often coexist, leading to a condition termed "osteosarcopenia". Globally, the pooled prevalence of sarcopenia in patients with knee OA is estimated at approximately 25.07%, significantly higher than in the general population.

Regime for Vitamin D Maintenance in Post-Operative Patients

Vitamin D plays a significant part calcium and phosphate haemostasis, thus, intrinsically critical for bone health. Increasing evidence also reveal that insufficient serum vitamin D levels also result in poor muscle health with such individuals having a compromised muscle building potential (4 times slower muscle building). Muscle health is a critical component of a post-surgical patient recovery, with impaired muscle function leading to reduced functional ability, resulting in a poorer quality of life. Poor muscle health also has negative repercussion on survivability, with reduced overall, and disease-specific survival, especially shown in cancer patients. Thus, maintenance of vitamin D levels post-surgery may be more critical than previously thought.

Association Between Sarcopenia, Fatigue and Orthostatic Intolerance in Geriatric Patients: A Case Control Study

This study aims to explore the relationship between sarcopenia, fatigue, and orthostatic intolerance in older adults. It will be conducted among geriatric patients attending Ain Shams University Hospitals. Participants aged 65 years and older will be divided into two groups: those with sarcopenia, diagnosed according to the European Working Group on Sarcopenia in Older People 2, and age- and sex-matched controls without sarcopenia. The study will compare levels of fatigue and the presence of orthostatic intolerance between the two groups. The findings are expected to improve understanding of how sarcopenia is associated with fatigue and orthostatic symptoms in the elderly population, which may help guide better clinical assessment and management.
