Active clinical trials for "Syndrome"

BACKGROUND. Sustained lung inflation (SLI) associated to an adequate PEEP may help the efficacy of the respiratory effort in lung of preterm infants at risk for respiratory distress syndrome (RDS) and reduce need of mechanical ventilation (MV). The investigators aim will be to demonstrate the hypothesis that the introduction of SLI in the delivery room protocol may reduce the need of MV in preterm infants. STUDY DESIGN: Multicenter prospective randomized controlled trial. The study will be carried out at the neonatal care units of the Careggi Infants with a gestational age between 25 and 28 weeks will be eligible and randomized at birth to receive SLI or not. Peak inflation pressure (PIP) of 25 cm H2O will be delivered for 15 seconds and then reduced to a positive end expiratory pressure (PEEP) of 5 cm H2O. Primary endpoint will be the need of MV within the first 72 hrs of life (excluding the transient tracheal intubation for surfactant replacement: e.g. INSURE). Population size: hypothesizing that SLI maneuver might decrease the need of MV during the first 72 hours of life from 35 to 20% the investigators calculated that 138 newborns must be enrolled in each groups to detect this difference statistically significant with 80% power at 0.05 level.

Idiopathic nephrotic syndrome (INS) is the most frequent glomerular disease in childhood. Currently, all children with INS are treated at onset with steroids. The optimal duration and dosage of steroid therapy is debated. For each patient, the challenge is to minimise potential side effects of steroids, while achieving a good clinical response. The aim of our study is to assess the benefits and potential adverse effects of a prolonged initial corticosteroid regimen, for the treatment of the initial episode. The results will be compared with data obtained retrospectively. In addition genetic studies will be undertaken with the aim of evaluating pharmacodynamics of steroid treatment with the ultimate goal to individualise treatment in single patients. Study group: children aged 6 months - 18 years, diagnosed with an initial episode of idiopathic nephrotic syndrome Control group: data of children with a onset INS between January 2007 and December 2009 from the same area of the study group and treated with a short steroid regimen will be retrospectively analysed and compared

Platelets play a key role in the athero-thrombotic process. However, the in vivo mechanism accounting for thrombus growth at site of coronary atherosclerotic lesion has not been fully elucidated. While platelet adhesion and aggregation on the thrombogenic core of atherosclerotic plaque is an established mechanism for thrombus growth, the role of systemic factors, which may contribute to thrombus via amplification and propagation of platelet aggregation, is still to be clarified. There is a growing body of evidence that lipopolysaccharides (LPS), are implicated in athero-thrombosis. Circulating levels of endotoxins have been associated with human atherosclerosis progression, particularly in smokers or in patients with infections. Furthermore, endotoxins seem to be implicated in the thrombotic process through several mechanisms including up-regulation of macrophage tissue factor expression and amplification of platelet response upon interaction with Toll-like receptor 4. The relationship between endotoxins and platelets may be relevant in the context of acute coronary syndromes as endotoxins could locally amplify platelet-derived thrombus growth but this issue is still unexplored. Previous studies demonstrated that low-grade endotoxemia is detectable in human circulation, likely as consequence of enhanced gut permeability, and may be responsible for leucocyte-platelet aggregate and eventually thrombosis. The investigators hypothesize that low-grade endotoxemia may be observed in patients with coronary heart disease and may favor, at site of coronary unstable plaque, thrombus growth. To explore this issue, Escherichia Coli (EC)-LPS concentration and biomarkers of platelet activation will be measured in coronary thrombus and intra-coronary blood of patients with STEMI and stable angina (SA), respectively, and in peripheral circulation of both patients and controls. EC DNA will be searched in serum of all patients by polymerase chain reaction (PCR). Furthermore, to substantiate that LPS could be biologically active, immune-histochemical analysis of thrombi and in vitro studies will be performed to assess the interplay between LPS and platelet activation.

In this observational case-control study investigators aimed to assess the serum levels of adipokines such as Apelin, Chemerin and adiponectin in patients with irritable bowel syndrome (IBS), and compare it with healthy controls. Furthermore, investigators evaluated the possible correlation of these adipokines with IBS-QoL, IBSSS, GI symptoms and other clinical and psychological disorders.

The purpose of this study is to identify psychopathology (psychiatric symptoms) that can differentiate between Schizotypal Disorder (SD) and Asperger Syndrome (normal IQ, no language impairment Autism Spectrum Disorder) (AS) in young adults. With our present knowledge, the differentiation between AS and SD can be difficult, as they both present with social difficulties, odd (but not psychotic) behaviour, and a 'feeling of not being as everyone else'. Studies suggest that adults with AS symptoms are either overlooked, or diagnosed within the schizophrenia spectrum in Adult Psychiatry. A 'correct' diagnosis is important, as it is the first step towards the most optimal plan, treatment and rehabilitation for the patient. The only way to diagnose psychiatric illness is the description of present psychopathology. To identify symptoms that can differentiate between the two disorders, we will use semi-structured interviews to explore present psychopathology in young adults with typical symptoms of SD and AS respectively, with special focus on presence of alterations in self-experience. Alterations in self-experience are typical for the schizophrenia spectrum, and are therefore not thought to be equally present in AS and SD. The hypotheses are that the total level of altered experiences is higher in SD, than in AS, and with a different pattern of altered experiences in SD than in AS. If the hypotheses are true, an examination of altered self-experience will be valuable to aid clinical differentiation between the two disorders.

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.

This clinical study is designed to evaluate the providing of a computational prediction engine for optimization of personalized nutrition Personalized recommendations for effective diet, lifestyle and activities based on the patient's parameters measurements and reactions will be provided on a bi-weekly basis, all Lab tests and dietician control will be performed twice a month.

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

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.
