Tracking Neurodegeneration in Early Wolfram Syndrome

Type 1 DiabetesDiabetes Insipidus2 more

The goal of this study is to determine the pattern of early neurodegenerative changes in WFS (Wolfram Syndrome). The investigator will perform cross-sectional and longitudinal assessments of youth with WFS, targeting sensitive neural systems with quantified neuroimaging and behavioral measures. In addition, the investigator will establish the utility of a WFS severity rating scale (WFS Unified Rating Scale or WURS). Preliminary data support the feasibility of this approach and its potential to generate important new information about neurodevelopmental and neurodegenerative patterns in WFS. This work is necessary to position the field for future clinical trials to test interventions for WFS neurodegeneration. Ultimately, a better understanding of the trajectory of neurodegeneration in WFS and the development of effective interventions may be relevant to other more common neurodegenerative and endocrine (Type 1 and Type 2 diabetes) diseases in which ER stress has been implicated.

The Impact of Metabolic Syndrome on Patients Undergoing Elective Laparotomy

Metabolic SyndromeAnesthesia2 more

Worldwide, the rising incidence of obesity has led to the identification of an obesity related syndrome, called metabolic. This syndrome is characterized by central obesity, hypertension, insulin resistance and altered lipid levels. Taking into consideration the rising incidence of obesity, anesthetists will more frequently encounter patients with metabolic syndrome, in their everyday practice. Moreover, the comorbidities that are related to the metabolic syndrome, increase the risk for perioperative complications. Therefore, strategies that will evaluate and modify the risk will be of great importance in the management of these patients, in order to maximize peri-anaesthetic and surgical safety. The aim of the study is to assess the incidence of metabolic syndrome and the impact of its presence on the outcome of patients undergoing elective laparotomy.

Gastrointestinal Symptoms in Postural Orthostatic Tachycardia Syndrome

Postural Tachycardia Syndrome

Patients with POTS experience significant gastrointestinal symptoms. Current evidence suggesting that abnormal post-ganglionic sympathetic function could play a role in the pathophysiology of these GI abnormalities. Sympathetic fiber regulate motor and the postprandial GI peptides secretion. The focus of the present proposal is to determine glucose homeostasis, GI motility, and their association with GI and cardiovascular symptoms in POTS patients versus healthy controls. Furthermore, we will determine differences in these outcomes in POTS patients with and without evidence of postganglionic sympathetic fiber neuropathy. As a long-term goal, this study can lead us to understand the pathophysiology of common co-morbidities in patients with POTS to provide new treatment approaches and prevention strategies.

Mobile Self-Management of Irritable Bowel Syndrome for Adolescents

Irritable Bowel SyndromeAbdominal Pain

The objective of the proposed research is to conduct user testing of a mobile-based self-management support intervention for adolescents and young adults with Irritable Bowel Syndrome (IBS), a chronic digestive condition. The application (app; BodiMojo Buddy) uses a virtual coach that can serve to increase patient engagement through interactive skill-building, self-care, and mindfulness-based cognitive behavioral activities. If the BodiMojo Buddy mobile app is successful, it will have a significant public health impact by providing a mobile resource to the 10-15% of the US population who suffer from IBS and potentially improving health outcomes and reducing significant costs to the US healthcare system. Study participation involves participants downloading and using the app for 30 days. During the 30 days, participants will interact with the app by inputting their current mood, receiving supportive feedback from the app, reading messages, and doing brief activities (such as relaxation activities, etc.). Before and after the 30 days of user testing, participants will complete a few brief questionnaires about their behavior, how their symptoms affect their life, and how they receive support from others. These questions will take around 20 minutes to complete at each administration.

Development of an in Vitro Hematopoietic Culture System and Application to Myelodysplastic Syndromes....

Hematopoietic Cell ProliferationMyelodysplastic Syndromes

Myelodysplastic syndromes (MDS) are myeloid hemopathies characterized by ineffective clonal haematopoiesis, peripheral cytopenias and a predisposition to the occurrence of acute myeloid leukemias. Their diagnosis involves a cytological evaluation of the medulla, while their prognosis, in addition to extrinsic factors depending on the patient himself (age, comorbidities), intrinsic factors. The cytological evaluation is subject to a certain subjectivity since qualitative and the diagnosis is sometimes difficult in the absence of marker of clonality. More and more studies emphasize the interest of flow cytometry (CMF) in the diagnosis of SMD: by looking for qualitative and / or quantitative aberrations of the expression of membrane markers, CMF allows to establish scores Diagnosis that we have put in place within the laboratory. However, these studies are based on a static model that studies the phenotypic characteristics of patients at a given time but does not really reflect ineffective hematopoiesis. A dynamic model for in vitro reproduction of hematopoiesis would be an innovative tool for the study of SMD. This project aims to develop and standardize a system of differentiation in liquid medium of hematopoietic stem cells (CSH) in mature cells by studying each stage of the differentiation in terms of proliferation, apoptosis and phenotypic expression. HSCs will be obtained by CD34 + sorting from the medullary sample at diagnosis: the investigator will study cell proliferation, apoptosis and the acquisition of surface markers, in order to identify the quantitative and qualitative abnormalities associated with the differentiation of haematopoietic progenitors Smart. This should make it possible to identify diagnostic and prognostic factors in terms of response to treatment, acutism and survival.

Postmastectomy Pain Syndrome in an Indian Cancer Hospital

Pain SyndromeMastectomy1 more

Breast cancer is the most common cancer in women in India and accounts for 27% of all cancers in women. Incidence rises in early thirties, peaks at 50-64 years. Approximately 48% are below 50 years of age. Most present when symptoms develop, so are 2B and beyond. Treatment depends on the stage of the disease. Surgical removal of the tumour is part of the treatment attempting a cure. Simple mastectomy involves removal of breast tissue without axillary lymph node dissection or removal of chest wall muscles. Radical mastectomy involves removal of the entire breast, skin, pectoralis major and minor muscles and ipsilateral axillary lymph nodes. Modified radical mastectomy involves removal of the breast and ipsilateral axillary lymph nodes. The pectoralis muscle is preserved. Breast conserving surgery involves removal of tumour with or without axillary dissection. The extent of surgery tells us about the nerve damage, local tissue handling. For example operating in upper and outer quadrant of breast and axilla increases nerve handling in that particular region. Local radiation also plays a role. Persistent pain after mastectomy was first reported in the 1970s by Wood and defined by International Association for Study of Pain (IASP) as pain in the anterior aspect of the thorax, axilla, and/or upper half of the arm beginning after mastectomy or quadrantectomy and persisting for more than three months after surgery and known as Postmastectomy pain Syndrome (PMPS). It is a common problem, with a 25- 60% incidence. The pain is described as burning or tenderness with paroxysms of lancinating, shock-like pain, and also described by some as dysesthesia (perception of non noxious stimuli as painful). Risk factors for PMPS include age, raised Body mass index (BMI), severity of postoperative pain, type of surgery, susceptibility to pain with a history of other pains such as headache and dysmenorrhoea. Axillary hematoma and postoperative radiotherapy have also been implicated in the development of PMPS. Tata Memorial Hospital, is a tertiary cancer institute in India. Around 4000 patients with suspected breast cancers register annually at the hospital and approximately 2800 breast cancer surgeries are performed yearly. Very few studies on PMPS in Indian population exist. We therefore plan to identify the incidence of PMPS in our patients and also the severity of pain along with its impact on daily function and quality of life

Efficacy of Heat-shock Protein (HSP) Inhibitors in Myeloproliferative Syndromes (MPS)

Myeloproliferative Syndrome

Heat-shock proteins (HSP) have been very highly conserved throughout the evolution of species and are characterized by their chaperone function, thanks to their ability to prevent aggregation and to promote the renaturation/break down of damaged proteins. Among other targets, they also chaperone JAK2, a key step that is deregulated in signalling in myeloproliferative syndromes (MPS) because of the JAK2V617F mutation. These HSP also have a potent cytoprotective action through their multiples inhibiting effects on apoptotic processes. Little is known about levels of HSP expression, in particular for HSP70 and HSP27, in MPS cells. However, in vitro studies of different cell models have shown the interest of HSP90 inhibitors in slowing cell proliferation in MPS. These results have been confirmed in animal models with results in terms of blood counts and overall survival. In addition, it seems that the V617F mutated form of JAK2 is more sensitive than the wild-type to HSP90 inhibitors. Finally, inhibitors of HSP90 remain efficacious with regard to the inhibition of cell growth, even in cases of resistance to JAK2 inhibitors. Nonetheless, HSP90 inhibitors are known to stimulate the expression of other HSP, notably HSP27 and HSP70, which are, through their properties, tumorigenic and could lead to an escape phenomenon. Thus the combined use of several HSP inhibitors could be beneficial, and eventually present synergistic effects on the inhibition of tumour processes.
