Goat Milk-Derived Formula vs. Undiluted Goat Milk in Infants Unable to Exclusively Breastfeed: Growth and Biomarker Analysis

The goal of this clinical trial is to learn if Goat Milk-Derived Formula Alternatives (GMDFA) are safe and effective for infants who are unable to be exclusively breastfed. It will also study growth patterns, biological markers, and gut microbiome differences among infants receiving GMDFA, undiluted goat milk, or breast milk. The main questions it aims to answer are: 1. Do infants receiving GMDFA show similar growth patterns to those who are breastfed? 2. Are biological markers of gut health and nutrition (such as calprotectin, lipocalin-2, CRP, and claudin) comparable between the groups? 3. How do feeding types (GMDFA, goat milk, or breast milk) influence the infant gut microbiome composition, metabolic pathways, and lipid profiles? 4. Is GMDFA a safe and nutritionally adequate feeding option for infants unable to be exclusively breastfed? We will compare GMDFA, undiluted goat milk, and breast milk (reference group) to evaluate infant growth, gut health, and metabolic outcomes. Participants will: Be randomly assigned to one of three feeding groups: GMDFA, undiluted goat milk, or breastfed Attend regular follow-up visits for growth measurements and sample collection (blood, stool, and breast milk where applicable) Have feeding practices monitored and recorded through caregiver interviews and feeding logs Additional Analyses: Microbiome analysis: to identify gut bacterial diversity and composition across feeding groups Metagenomic analysis: to explore functional genes and metabolic pathways related to nutrition and gut health Lipidomic analysis: to assess differences in lipid and fatty acid profiles in breast milk, goat milk, and infant samples

Semaglutide Treatment in Type 1 Diabetes

The goal of this clinical trial is to investigate the efficacy of semaglutide on body weight, insulin dose requirements and improvements in glucose control and safety aspects in regards to risk of hypoglycemia and diabetic ketoacidosis for patients with established Type 1 Diabetes.

Bio-significance of LPC16:0 in Fibromyalgia

Fibromyalgia (FM) is a very common but mysterious pain disorder characterized by chronic widespread muscular pain. Fatigue, anxiety and depression are common comorbidities. The syndrome is commonly associated with several symptoms, including fatigue, sleeping disturbance, cognitive impairment, and comorbid pain syndrome, especially irritable bowel symptoms and temporomandibular disease. Anxiety and depression are common psychiatric co-morbidies. Daily stress is believed to trigger or aggravate pain conditions. These symptoms can markedly affect patients' quality of life, and even lead to disability. So far, the etiology and pathogenesis are largely unknown, and diagnostic biomarkers and curative treatment remain to be developed. Recent technological advances enable scientists to explore mechanisms by genetic, transcriptomic, proteomic, and metabolomic researches. However, no definitive result has been concluded for clinical practice so far. In this study, the investigators use tailored questionnaires to evaluate fibromyalgia and associated symptoms, including numeric rating scale for soreness, widespread soreness index, Fibromyalgia impact questionnaire, Hospital Anxiety and Depression Scale, and perceived stress scale. The investigators also use metabolomics and lipidomic approach to probe the potential pathophysiology of fibromyalgia. In our prior translation research (PMID: 32907805), the investigators found that excessive LPC16:0 resulting from lipid oxidization inflicts psychological stress-induced chronic non-inflammatory pain via activating ASIC3. In this content, our prior translational research identified a potential nociceptive ligand that causes fibromyalgia symptoms, which is likely to function as biomarkers for diagnosis or disease monitor. In the current clinical investigation, the investigators aim to reversely translate the novel findings in animal studies and validate the bio-significance of LPC16:0 for fibromyalgia with clinical approaches.

Metabolomic and Lipidomic Analysis Predicts Immunotherapy-related Adverse Events in Gastric Cancer Patients

This study comprehensively examines metabolic and lipidomic dynamics in gastric cancer patients initiating PD-1/PD-L1 inhibitor therapy, employing a longitudinal design with pre- and post-treatment patients. The primary objectives include identifying irAE-associated metabolic and lipid biomarkers, developing predictive risk models, and evaluating the prognostic value of these molecular profiles. The findings are expected to contribute significantly to personalized treatment strategies and improved clinical decision-making in immunooncology.

Cancer-associated Muscle Mass - Molecular Factors and Exercise Mechanisms

Muscle mass loss is a common adverse effect of cancer. Muscle mass loss occurs with or without reduction in body weight. Cancer cachexia (CC) is the involuntary loss of body weight of \>5% within 6 months and it occurs in 50-80% of patients with metastatic cancer. It is estimated that CC is a direct cause of up to 30% of all cancer-related deaths. No treatment currently is available to prevent CC, likely because the chemical reactions that causes of this devastating phenomenon in unknown. No treatment currently is available to prevent muscle mass loss in patients with cancer but is urgently needed as the reduced muscle mass and function is associated with impaired physical function, reduced tolerance to anticancer therapy, poor quality of life (QoL), and reduced survival. There is evidence of an interdependence between informal caregiver (e.g. spouse) and patient QoL. Thus, identifying caregiver distress and needs can potentially benefit QoL for patients with cancer cachexia. Despite the enormous impact on disease outcomes, it is not known why the loss of muscle mass and function occurs and very few studies have investigated the underlying molecular causes in humans. In particular, there is a severe lack of studies that have obtained human skeletal muscle and adipose tissue sample material. Such reference sample materials will be invaluable to obtaining in-depth molecular information about the underlying molecular causes of the involuntary but common muscle mass and fat mass loss in cancer. At a whole body level, cancer cachexia is associated with reduced sensitivity to the hormone insulin, high levels of lipids in the blood, and inflammation. Within the skeletal muscle, the muscle mass loss is associated with elevated protein breakdown and reduced protein build-up while emerging, yet, limited data also suggest malfunction of the power plants of the cells called mitochondrions. The role of malnutrition and how it contributes to weight loss is understood only to the extent of the observed loss of appetite and the reduced food intake because of pain, nausea, candidiasis of the mouth, and breathlessness. Evidence is increasing that the environment of the intestinal system could be implicated in cancer cachexia, yet, the possible effect of cancer and the cancer treatment on the intestinal environment is not understood. Thus, large and as yet poorly understood details of this syndrome precede a later weight loss. Exercise training could help restore muscle function and how the chemical reactions works in cancer. In healthy people, and patients with diabetes, cardiovascular disease, and obesity exercise potently improves health. Exercise has been thought to slow down the unwanted effects of cancer cachexia by changing the reactions mentioned above. Thus, there is a tremendous gap in our knowledge of how and if exercise can restore the cells power plants function, muscle mass, strength, and hormone sensitivity in human cachexic skeletal muscle. Tackling that problem and examining potential mechanisms, will enable us to harness the benefits of exercise for optimizing the treatment of patients with cancer. The data will provide novel clinical knowledge on cachexia in cancer and therefore addressing a fundamental societal problem. Three specific aims will be addressed in corresponding work packages (WPs): * investigate the involvement of hormone sensitivity of insulin and measure the chemical reactions between the cells in patients with lung cancer (NSCLC) and describe the physical performance and measure amount of e.g. muscles and adipose tissue across the 1st type of cancer treatment and understand how that is related to the disease and how patients and informal caregiver feel (WP1). * find changes in the chemical reactions in skeletal muscle, adipose tissue (AT), and blood samples in these patients, to understand how to predict how the disease will develop (WP2). * measure changes of skeletal muscle tissue in response to exercise and see if it might reverse the hormone insensitivity and improve muscle signaling and function (WP3). The investigators believe that: * the majority of patients with advanced lung cancer, at the time of diagnosis already are in a cachectic state, where they lose appetite, and have hormonal changes, and an overall altered chemical actions between the cells affecting both muscle mass and AT. The investigators propose that all this can predict how the disease will progress, and how patient- and informal caregiver fell and how they rate their quality of life. * lung cancer and the treatment thereof is linked with changes in the blood, the muscle tissues, and the adipose tissues, especially in patients experiencing cachexia, that could be targeted to develop new treatment. * exercise can restore the muscles and improve insulin sensitivity and improve the function of the cells power plants in patients with lung cancer-associated muscle problems.
