As part of the mandatory annual assessment of physical fitness, soldiers are required to complete a standardized military march. A total of 100 healthy volunteer participants will be recruited from soldiers serving at the Bundeswehr Hospital Ulm. During this march, physiological and metabolic parameters will be assessed. At baseline, anthropometric data and information on medical history, lifestyle, and fitness status will be collected, including a validated questionnaire on physical activity. Blood and urine samples will be obtained to determine routine laboratory and metabolic parameters, and body composition will be assessed using bioelectrical impedance analysis. In addition, selected sensors will be applied to continuously record physiological data. Participants will then complete a 6 km march carrying 15 kg of equipment. After completion of the march, sensors will be removed and additional blood and urine samples will be collected to evaluate metabolic responses to physical exertion, including catecholamine levels.

Weight loss is a known negative prognostic factor in amyotrophic lateral sclerosis (ALS). Over the last years, various interventional studies targeting the energy deficit in ALS yielded promising results; however,it is still unclear which kind of nutrition or nutritional supplement is most beneficial. Moreover, there is lack of evidence regarding interventions in patients with a PEG in later disease stages.In a pilot study conducted in 2013, it was demonstrated that body weight can be stabilized in ALS by applying either a fat-rich or carbohydrate-rich high-caloric food supplement. In 2014, Wills et al. conducted a placebo-controlled randomized controlled pilot study, which indicated that a carbohydrate-rich, hypercaloric diet, consisting in 125% of estimated energy requirements as determined by indirect calorimetry, in patients fed via percutaneous endoscopic gastrostomy was safe and well tolerated. Moreover, these patients showed longer survival than patients fed with a fat-rich, hypercaloric diet or an isocaloric diet . Hypercaloric, high-carbohydrate diet also showed beneficial effects on body weight and Body Mass Index . Although these results were promising, the low number of patients (n=24) was a severe limiting factor of this study. The aim of this study is to investigate the effect of a hypercaloric PEG nutrition, consisting of 120% of estimated calorie requierements, compared to an isocaloric nutrition. Individual energy requirement is determined by performing indirect calorimetry and activity questionnaire. The investigators hypothsize, that a hypercaloric PEG nutrition slows down disease progression as measured by neurofilament light chains (NfL) in serum after 6 months compared to placebo. Power calculation relies on the results of the lipids and calories for ALS (LIPCAL-ALS) study which tested the effect of an oral high-caloric fatty nutritional supplement in ALS. The study revealed that NfL serum values declined significantly in the intervention group while remaining stable in the placebo group over the course of the study. Assuming a similar effect size, we calculated that 76 patients had to be included in the current trial.

This study aims at evaluating efficacy and tolerability of an ultra-high-caloric, fatty diet (UFD) compared to placebo in patients with amyotrophic lateral sclerosis (ALS).

This is a randomized controlled study evaluating safety and efficacy of repeated immunoadsorption versus immunoglobulins in steroid-refractory Chronic Inflammatory Demyelinating Polyneuropathy (CIDP).

This clinical trials aims to investigate the impact of parental metabolism during pregnancy on fetal epigenetic signatures. The metabolic profiles of both parents will be evaluated through a blood sample collected from the father and an oral glucose tolerance test administered to the pregnant mother. Additionally, epigenetic signatures will be assessed using parental blood samples. Fetal epigenetic signatures can be identified by analyzing fetal cell-free DNA that circulates in the mother's bloodstream.

The goal of this clinical trial is to clarify the interaction of central insulin action and physical activity with the immune system. Therefore, participants will undergo bicycle spiroergometer tests. This approach will be compared between days with insulin delivery to the brain as nasal spray and days with placebo spray. In another trial (NCT06552130) lean participants already have been tested. Significant effects on circulating cytokines could be identified. In this amendment, overweight persons in which brain insulin resistance is expected will be tested.

The goal of this clinical trial to clarify the impact of changes in thyroid hormone levels on glucose and lipid metabolism. Patients will be included in whom thyroid hormone levels are intentionally changed by treatment. In patients with Graves' disease, thyroid hormone levels will be lowered using medication, while in patients with thyroid cancer, thyroid hormone levels will be raised using medication. Oral glucose tolerance tests will be performed before treatment and at two time points after treatment begins to assess metabolic effects.

This study aims to leverage structural, functional, and metabolic magnetic resonance imaging (MRI) of the brain to identify imaging features that correlate with clinical parameters. It is hypothesized that individuals with metabolic diseases exhibit distinct functional and structural brain differences compared to healthy controls. These differences may evolve over time due to changes in whole-body metabolism or body weight, influenced by factors such as the natural progression of the disease or therapeutic interventions. Additionally, potential brain changes may correlate with body composition metrics, such as the fat content of specific body compartments. This is a prospective, single-center study conducted at Ulm University Hospital, designed to track the clinical and imaging histories of patients with metabolic diseases and compare them to healthy individuals. Eligible participants include adults (aged 18 and older) capable of providing informed consent. Recruitment will occur through routine clinical care or existing research studies. To provide a comprehensive understanding, the study will include both cross-sectional analyses and longitudinal follow-up of participants, integrating repeated assessments during routine medical visits.

Genetic obesity results from changes in specific genes that affect appetite regulation, metabolism, and fat storage. Its severity and associated health issues vary depending on the genetic cause. In some cases, hormonal imbalances, developmental delays, or other complications may also occur. Identifying the genetic cause is essential for personalized treatment and understanding potential symptoms. As genetic obesity is rare, specialists often encounter few patients with diverse genetic backgrounds and clinical features. Therefore, collecting global data is crucial to improve our understanding of the condition's progression, complications, and treatment responses for each genetic subtype. To support this, the International Genetic Obesity Registry (iGO Registry) has been established to gather detailed patient information on genetic obesity. This registry will help advance research and improve clinical care for affected individuals. It will collect data from routine outpatient visits, focusing on relevant diagnostic and treatment information on an international level.

Given the lack of knowledge on lipodystrophies, the medical and social responsibility for the persons affected by it calls for the monitoring of the progression over long periods of time. Sensible clinical and basic research into rare diseases such as lipodystrophy is only possible in multi-location networks with sufficient case numbers. Also, reliable information on the incidence of certain manifestation patterns, health status, etc. is of utmost importance for health care and health policy in this rare disease. Therefore, the European Consortium of Lipodystrophies (ECLip), an association of European experts on lipodystrophy, has launched a registry (OSSE) for lipodystrophies which is committed to help to improve the research conditions by consolidating this kind of information in a registry.

This study is designed as an explorative study aiming at exploring safety and efficacy of immunoadsorption (IA) in patients with Chronic Inflammatory Demyelinating Poly-neuropathy (CIDP) compared to intravenous immunoglobulins (IVIg) and methyl-prednisolone (MP). For this purpose, approximately 140 patients with CIDP will be included within the framework of the German multicenter network "Kompetenznetz Peripherer Nerv" (KKPNS). The study will be purely observational. IA will be performed as an escalation therapy, i.e., in patients who did not respond to IVIg and/or MP treatment. Patients will be included in the study during ongoing IVIg or MP treatment and switched to IA during the 18-month observation period in case of an insufficient response. IA will be performed according to the therapeutic scheme of each participating center. A non-mandatory recommendation for number of sessions, treatment volumes, and frequency will be given (see below). Six-month follow-up visits including collection of standardized clini-cal data will be performed.

The goal of this clinical trial is to evaluate the influence of parasympathetic transmission from the brain to different metabolic organs. This transmission can be blocked with the muscarinic antagonist atropine. Participants will undergo an oral glucose tolerance test combined with a double tracer dilution technique either with atropine infusion or placebo. Healthy individuals and high-risk individuals will be compared to identify possible changes in signaling in high-risk groups. In addition, men and women will be included to take into account possible sex differences.

In the context of the COLORIZE study, it is being tested whether the endoscopic light mode Texture and Color Enhancement Imaging (TXI) is non-inferior to the standard White Light Endoscopy (WLE) in assessing inflammatory activity in patients with Inflammatory Bowel Disease (IBD). For this purpose, ileocolonoscopy is performed on patients diagnosed with IBD, and standardized image documentation will be carried out in both WLE and TXI modes. Step biopsies are taken, and clinically validated, endoscopic, and histological scores are used.

This study focuses on improving fertility preservation and long-term care for children, adolescents, and young adults (CAYA) undergoing cancer treatments or stem cell transplantation. These treatments can harm fertility, and ensuring that patients receive the right support and follow-up care is critical. The main study goals are: 1. Understanding Fertility Risks: Researchers aim to identify factors that predict fertility problems after cancer treatments, such as the type of therapy, hormone levels, body composition, or genetic predispositions. 2. Addressing Patient and Family Needs: The program will explore the concerns, needs, and challenges faced by young patients and their parents regarding fertility. It will also examine how these issues affect their quality of life. 3. Improving Clinical Care: Current practices in fertility preservation and counseling will be studied to identify gaps and improve care structures. To achieve these goals, the program will: * Create a database to collect and analyze medical data from patients before, during, and after cancer treatments. * Study the prevalence and long-term effects of fertility problems in young patients. * Document medical interventions like fertility preservation methods (e.g., freezing eggs or sperm) and treatments for late effects. * Assess patients' and families' fertility-related quality of life and their informational needs. Ultimately, the project aims to establish an interdisciplinary center to support fertility preservation and improve the quality of care for young patients facing cancer and its treatments.
