With increasing age and the additional impact from the bowel cancer and the chemotherapy and/ or radiotherapy it has been described that testosterone (a male hormone produced naturally in the body) levels are reduced. Testosterone has an impact on numerous body functions including the muscle mass and quality. Previous studies have identified that muscle mass is reduced as a result of ageing but also because of the deleterious effect of cancer and chemotherapy and/or radiotherapy. There is growing evidence from published studies that patients with better muscle mass and quality, do better after surgery. Mr Jenkins and his team are therefore looking at ways, the investigators can try and prevent or reduce this muscle loss and therefore improve patient outcomes. The aim of this study is to assess whether using testosterone replacement therapy in the form of a topically applied gel daily for a total of 12 weeks, is feasible and acceptable by the patients who are diagnosed with colorectal cancer and are waiting to undergo surgery. The investigators will also collect information related to the testosterone replacement therapy such as questionnaires on the quality of life, fatigue and muscle mass, and blood biomarker changes in the blood.
Chronic kidney disease (CKD) has become a global public health priority over the past few decades, affecting 10-12% of the adult population and has received increasing attention. Sarcopenia describes a generalizes degenerative skeletal muscle disorder involving the loss of muscle mass, muscle function and/or physical performance. Indeed, Sarcopenia is a condition with many causes and it can be considered "primary sarcopenia" when no other cause is evident but ageing. While in the clinical practice, it also occurs in patients with chronic diseases, such as chronic kidney disease, which can be considered "secondary sarcopenia". Notably, the occurrence of sarcopenia in CKD patients is not only related with ageing, the accumulation of uremic toxins, inflammation, insulin resistance, malnutrition and oxidative stress also contribute to the muscle depletion. Moreover, sarcopenia increased risk of falls and fractures, impaired ability to perform activities of daily living, disabilities, loss of independence and increased risk of death. Hence, it is of great significance to prevent the occurrence and development of sarcopenia in patients with CKD. The purposes of this project were to investigate the prevalence of sarcopenia, further explore the risk factors for sarcopenia and detect the relationship between sarcopenia and outcomes in CKD patients.
The presence of sarcopenia before lung resection surgery might be an important factor of short-term and long-term prognosis in lung cancer patients. Through this study, investigators plan to demonstrate evidence whether sarcopenia is a useful clinical biomarker for risk stratification in elderly patients undergoing lung cancer surgery.
The placement of TIPS (transjugular intrahepatic portosystemic shunt) is the most effective strategy to treat complications of portal hypertension. However, the threat of developing post-TIPS complications diminishes its use and applicability. Hepatic encephalopathy (HE) is the most feared and frequent post-TIPS complication, affecting between 25-54% of patients. Available treatments against HE are only partially effective. Therefore, the best existing strategy is to accurately select patients for TIPS excluding those presenting known high risk factors associated to post-TIPS HE. Despite applying this approach, the incidence of post-TIPS HE still remains very high. The investigators hypothesize that a better identification of risk factors for post-TIPS HE, together with the introduction of therapeutic interventions modulating pathophysiological mechanisms involved in post-TIPS HE development - among which sarcopenia stands out- would lead to a reduction in the incidence of HE and, eventually, to an increase in the number of patients benefiting from TIPS. Thus, our project is aimed at 1. Demonstrate that a 12 weeks lifestyle intervention based on resistance training and nutritional counseling can reduce sarcopenia and, ultimately, post-TIPS HE. 2. To study predictive factors of post-TIPS HE, focusing on the role of factors that have never been evaluated in the setting of TIPS: gut microbiome and cognitive function
Hong Kong is facing a significant societal challenge - a rapidly aging society. The proportion of the population aged 65 and over in Hong Kong increased from 16.6% in 2005 to 20.1% in 2020. The number of people aged 65 or older worldwide is estimated to reach 1.6 billion by 2050. In terms of quality of life, a major difficulty that many older people experience is a severe limitation in mobility and manipulability in their daily life, resulting in tremendous social and economic challenges. Hence, the investigators propose to develop innovative intelligent robotics systems to improve mobility and manipulability, prevent falls, enhance independence, and improve the quality of life of older adults. In particular, the investigators propose a User-Centric Co-creation (UC3) approach to developing novel intelligent wearable robots to enhance mobility and manipulability. The UC3 approach will start with a psycho-social study to identify the individual needs of older adults for achieving mobility and manipulability, which then leads to determining kinesiology-based design parameters for personalized wearable robots. The robots will be developed based on novel hybrid soft/rigid structures integrated with intelligent sensors, distributed actuators, and cooperative control methods. The robotic devices will be tested with elderly users in a user- user-centric environment for evaluation and continuous improvement. The investigators have conducted preliminary studies of the proposed approach. The results of the preliminary studies have clearly shown the feasibility as well as the novelty of the proposed approach. It can be stated confidently that our multidisciplinary team of experts in engineering, gerontology and medicine will be able to work with the elderly community and potential users to successfully deliver the project objectives. Furthermore, an Impact Committee, consisting of leaders in Hong Kong's elder community, elderly care organizations and related industries, has been proposed. It will advise and facilitate the research team to ensure the maximum impact of the research results and successful technology transfer. Commercialization efforts will be embedded in every phase of the project to ensure that the results will both benefit the elderly community and contribute to the economic development of Hong Kong. The outcomes of this project will place Hong Kong at the frontier of global robotics research and technology, provide critical technology to transform the elderly care services in Hong Kong, and create opportunities for training the next generation of scientists and engineers in robotics technology in Hong Kong.
The aim of this study is to determine whether preoperative sarcopenia (low muscle strength/muscle mass) is correlated with time weighted average intraoperative hypotension in patients undergoing minimally invasive pylorus preserving pancreaticoduodenectomy.
The hand is important to perform activities of daily living (ADL). However, many people experience a loss of hand function as result of a traumatic brain injury, spinal cord injury, stroke or orthopedic problems, or due to ageing. To improve hand function, or reduce its decline, one can benefit from exercise therapy or use of assistive aids to improve ADL independence. A promising innovative approach combining both is a wearable soft-robotic glove that supports hand grip. With this glove, performance of functional activities can be supported directly, while also facilitating repeated use of the affected arm and hand during functional daily activities. One of our previous studies showed that besides a direct support effect, a therapeutic effect on performance was found after several weeks of using the soft-robotic glove as support during ADL. However, several participants reported complaints of increased pain and/or overload, mainly at the beginning of the trial. Clinicians suspect that a (too) high intensity of hand use compared to normal is contributing to this observation. This might be related to more fatigue experienced when using the glove in high-demand tasks, due to a larger movement capacity (faster, further, more repetitions) and can be associated with decreased blood perfusion/lower saturation levels at muscular level and altered muscle activation and movement coordination. Therefore, the primary objective is to examine the effect of use of the assistive soft-robotic glove during strenuous ADL tasks on the kinematic movement profile, compared to not using the soft-robotic glove. Secondary objectives are to examine whether pain or discomfort is experienced in strenuous activities with the soft-robotic glove as well as the characteristics and locations of such pain/discomfort, and to examine whether use of the glove is associated with increased handgrip strength, larger number of ADL task repetitions, diminished blood perfusion / reduced tissue saturation at the muscle and/or changes in muscle activity.
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.
We are conducting a study in different centers in Spain in elderly people, in order to assess the effectiveness of a physical exercise intervention program in people in a situation of frailty. Frailty in an elderly person is a situation in which, although there are no major differences in their usual abilities, the person presents a certain decrease in their capacities. This slight decrease is usually accompanied by a progressive deterioration.
