The principal means of measuring motor impairment in Huntington disease (HD) is the Unified Huntington's Disease Rating Scale (UHDRS) total motor score, which is subjective, categorical, requires significant training to administer correctly, and only captures impairments in clinic. In this Direct to Phase II SBIR we will develop a wearable sensor system for objective, sensitive, and continuous assessment of Huntington's chorea during activities of daily living. The developed technology could be used clinically to detect changes in motor function in response to medications, or could be used scientifically to expedite and reduce the cost of early stage pharmaceutical clinical trials.

This study is conducted to explore the feasibility and value of Intraoperative ultrasonographic localization of pulmonary nodules in video-assisted thoracoscopic surgery (VATS).

The study was planned with the aim of comparison of postural sway responses at menstrual cycles in women with and without the dysmenorrheal syndrome. Women will stand on a postural sway evaluation system on the first day of the menstrual cycles and a well-being day which they will select. Every participant will be evaluated same tool. They will be assessed for three times at every session: 1st evaluation will be performed at the normal standing position. 2nd evaluation will be performed at the normal standing position while individuals saying the numbers from 200 to 1. 3rd evaluation will be performed at the normal standing position while individuals holding the mini blocks on their hands.

Systemic lupus erythematosus is systemic autoimmune disease characterized by a wide range of clinical manifestations, from skin and mucosal lesions to severe injuries in the central nervous system, kidneys and other organs. The presence of high titres of autoantibodies against nuclear components, immune complexes deposition, complement deficiency and lymphocytes infiltration in affected tissues, which causes tissue and organ damage are the main characteristics of the disease. Nowadays, many studies elucidate the essential role of autophagy in the occurrence, development and severity of systemic lupus erythematosus.

Cardiogenic shock is an uncommun pathology with a high mortatily rate around 45%. Veno arterial extracorporeal membrane oxygenation (VA-ECMO) is a temporary extracorporeal assist device which restore an adequate blood flow when a circulatory failure occures. VA-ECMO main indication is refractory cardiogenic shock whatever the etiology. Current medical care of terminal cardiac failure includes use of long-term mechanical circulatory support devices (MCSD) such as Left Ventricular Assist Device (LVAD). LVAD therapy may lead to heart transplant (bridge to transplantation), to recovery (bridge to recovery) or to permanent implantation (destination therapy). Few patients with refractory cardiogenic shock treated with VA-ECMO may secondarily need a long term MCSD with LVAD. LVAD long-term heart assist showed interesting survival rate when implantation occured (71% after 2 years follow-up and 45% after 4 years follow-up) out of acute heart failure situation. There are only few datas concerning LVAD implantion during refractory cardiogenic shock, with a mortality between 20 to 50% in different studies. In this way, in comparaison of current few datas on the subject of LVAD implantation under VA-ECMO, the investigators (15 french-speacking centers) would retrospectively describe a large population.

The primary function of epithelial tissues is to form a barrier between the body and the external environment, in order to protect the internal tissues from environmental stresses, by minimizing water loss and preventing the entry of pathogens, pollutants and allergens. Allergic disorders, such as atopic dermatitis, have been associated to an impaired epithelial barrier function. Indeed, defects in the epithelial barriers allow tissue-damaging factors to enter the tissue and thus activate the immune response. This study aims to establish a method to assess the epithelial barrier function in vivo by electrical impedance (EI) spectroscopy, a new technique for the characterisation of epithelial tissue. By this technique, a harmless electrical signal is sent through the skin and the response of the tissue is analysed, which is influenced by several cellular properties, such as shape, orientation and size. In order to validate this technique, skin of mice was treated with some molecules able to destroy the epithelial barrier. The investigators observed that, after damaging the barrier, a decrease of the EI can be detected, consistent with the type and degree of the damage. Based on this result, the investigators believe that this technique is a good candidate as an in vivo method to determine skin barrier defects, which might be used in the future as an early diagnostic tool for the prediction of the risk to develop atopic dermatitis in young subjects, allowing the possibility to apply in time possible preventive measures. In addition, this technique might be suitable for the evaluation of a given therapy during the hospitalisation. To confirm this hypothesis, in the present study patients with atopic dermatitis will be recruited. EI measurements will be performed in both lesional and non-lesional skin and values will be compared in order to detect any difference in the electrical response due to the inflammatory state. In addition, in order to evaluate whether these patients have an appreciable defect in their skin electrical behaviour, the investigators will compare non-lesional and lesional skin of patients with skin of healthy volunteers. Peripheral venous blood and skin biopsies will be collected, in oder to characterise several immune cell populations, to detect specific skin barrier mutations and to measure serum cytokines and immunoglobulins. These and some other parameters and will be analysed in order to identify a possible correlation with the EI.

The expression level of PD-L1 on tumor cells is a pivotal point which might have some influence on prognosis, especially for those who might use PD-1 or PD-L1 antibody for treatment. The aim of this study is to detect the expression of PD-1 on advaced osteosarcoma patient who might use these antibodies for treatment. All those specimen should be taken by pathologist and confirmed with high tumor cellularity.

To counteract long term sequelae from stroke, ultrarapid diagnosis and treatment, high quality multidiciplinary in-hospital care and optimal long term rehabilitation is required. In this study, the investigators are moving the essential first diagnosis and treatment out into the community close to where the patient live, thus shortening the all important time from debut of symptoms to thrombolytic treatment improving the prognosis of stroke patients.

After a surgery, the recovery of the previous health status of patients, such as walk, body care, sleep, diet, feeling of comfort, is one of the priorities of the perioperative medicine. The QoR-15 was designed to measure quality of recovery after surgery. It provided a valid, extensive and efficient evaluation of the postoperative quality of recovery. The primary objectives of this study is to translate the original QoR-15 questionnaire into French, and do a full psychometric evaluation of the French version. We will test its validity, reliability, responsiveness, and clinical acceptability and feasibility, with patients undergoing abdominal, orthopedic, […], gynecological surgery, in the University Hospital of Strasbourg. The secondary objectives will be to evaluate the quality of recovery of the patients who undergone surgery at Strasbourg University Hospital, and to evaluate the incidence of postoperative complications occurring within three months postoperatively and a possible association with the QoR-15F.
