Bladder cancer is the seventh cause of cancer mortality in France. Overall survival is poor, between 45 and 50% at 5 years. Optimal staging of lymph nodes and metastasis is crucial for treatment decision of muscle invasive bladder cancer (MIBC). Guidelines do not recommend FDG-Positron Emission Tomography (PET) Computed Tomography (CT), but rather CT for lymph node and metastatic staging, despite its low accuracy. We performed a retrospective analysis of patients undergoing PET CT for localized MIBC in two centers, to help define the utility of PET CT in this setting.
AFFIRM is an 8-session manualized group coping skills intervention focused on reducing sexual risk behaviours and psychosocial distress among SGMY. AFFIRM is delivered by two facilitators (primarily social workers and peers) through a combination of education and rehearsal (i.e., simulation of real-life experiences) in a manner that affirms participants' sexual and gender minority identities and experiences. AFFIRM is being tested in a five-year trial using a stepped wedge waitlist crossover design, where all participants receive the intervention in clusters.
Height and weight are important informations in clinical life. Medication is dosed by them and weight, especially overweight, is a risk factor for cardiovascular diseases. Mostly you have to rely on the self-reported informations, because there is plenty of work and little time to weigh and measure every patient. But can the investigators really trust this informations? Former studies have shown, that most of self-reported heights and weights differ from the measured ones. This fact might lead to a wrong dosage of medicine or underestimated risk factors. So the Cardial-MASS-Study tries to detect influencing factors on the reliability of self-reported informations especially among patients, treated at the cardiological department at Saarland University.
Gut microbiota modulation has effect on chronic liver disease
Despite new charachersitics of COVID-19 patients, critical care implementation seems to be similar to those with Acute Respiratory Distress Syndrome (ARDS) in intensive care units (ICU). Regarding the initial gravity of these patients, sedation and neuromuscular blockers are usually administrated, increasing the risk to develope an ICU-acquired weakness which is directly correlated to morbi-mortality and a burden during recovery. Respiratory symptoms are mostly related to dyspnoea and non-productive cough, with only 33% of COVID-19 patient having a bronchial hypersecretion ; consequently, chest physiotherapy is only implemented in after case-by-case evaluation. This unprecedented situation requires to identify how physiotherapy is being implemented in COVID-19 patients in ICU. This retrospective, multicentric study aims to identify the charactheristics of physiotherapy (type and time spent) implemented in Argentina, Belgium, Chili, France, Italy and Spain
Cerebral swelling is a major complication following aneurysmal subarachnoid hemorrhage.This study is a retrospective cohort aimed to predict the extent of brain swelling. Cerebral venous assessment can identify the risk of brain swelling and improve surgical outcomes.
Current methods of detecting glaucoma and monitoring its progression over time involve visual assessment of the optic nerve, thickness measurements of nerve tissue in the eye (using optical coherence tomography, OCT) as well as functional tests which measure peripheral, or side, vision. The objective of this study is to determine if a new technique of measuring blood flow in the eye, using OCT, can be used to better detect and/or monitor changes in glaucoma patients and suspects than these methods.
The investigators hypothesise that intact umbilical cord milking (I-UCM) will reduce neonatal morbidity and improve long term neurodevelopmental outcome in very preterm infants. All babies born less than 32 weeks gestation, meeting the inclusion criteria will be randomly assigned to either I-UCM or immediate cord clamping (ICC) and their short and long term outcome measures analyzed.
Primary Objective - To compare the effectiveness of 2 treatment protocols for patients with breast cancer-related subclinical lymphedema identified through bioimpedance spectroscopy, L-dex scores Secondary Objectives - To determine the necessary duration of intervention to reverse L-dex scores back to a normal range in patients with breast cancer-related subclinical lymphedema - To determine the time elapsed post-surgically to the development of subclinical lymphedema identified by bioimpedance spectroscopy, L-dex scores - To identify risk factors for the development of subclinical lymphedema in patients with breast cancer - To identify factors associated with the progression to clinical lymphedema following treatment of subclinical lymphedema as identified by bioimpedance spectroscopy, L-dex scores Women with breast cancer diagnoses and planned axillary lymph node procedures will receive pre-operative screening of arm volume with bioimpedance, which will capture baseline measurements. Then, subjects will undergo periodic screenings for the first 3 years following surgery. If a significant change in volume compared to baseline is detected with bioimpedance, subjects will be randomized to 1 of 2 treatment groups. The outcomes of 2 treatment protocols will be compared. Additionally, subjects will be screened each week during their treatment interventions to determine the necessary quantity of intervention before L-dex scores normalize.
Nasal mucus and nasal epithelium are the first defense barriers against allergens. Various proteins are found in nasal mucus that play a role in allergic rhinitis and reflect immune response to allergen exposure. The difference in the proteomic profile of allergic rhinitis patients and healthy controls can give insight about how the response works and which proteins could lead to either enhanced immune reaction or to defense response like augmentation of epithelial integrity. It is also known that the airway epithelium plays a crucial role in the regulation of airway immune responses and inflammation. Gene expression profiling is widely used to analyses complex disease. For the airway epithelium gene expression profile in diseased and healthy state as well as in baseline and provoked state can clarify the mechanism of defense reactions and the course of inflammatory processes. Nasal mucus proteins as consequence of different gene expression can be seen as part of the end products of this complex mechanisms and interactions between allergens and the epithelium. Nasal mucus proteins have different origins and production sites and gene expression does not necessarily result in functional metabolites. The aim of this proposed project is to try and analyze in a holistic proteomic approach the response to allergen on a genetic/genomic level from the nasal epithelium to protein/proteomic level in nasal mucus. This analysis gives us insight of how the different gene expression profiles result in a protein expression and further clarifies which proteins are directly originate from the epithelium and which are result of plasma exudation or underlie different regulatory processes. From allergic rhinitis patients and healthy controls nasal mucus, nasal mucosa, and serum will be obtained. Nasal mucus will be collected with a special suction device equipped with a mucus trap from the middle meatus under endoscopic control without touching the mucosa. Nasal mucosa will be obtained through nasal brushes under local anesthesia and put into primary culture. Serum prepared from blood samples. Patients with grass or tree pollen allergy will be included and allergic state will be determined by skin prick tests and RAST (Radio-Allergo-Sorbent-test). The aimed for sample size will be 15 patients per group. Samples will be obtained in and out of pollen season. Allergic patients will fill out a symptom score and samples will be taken when symptoms are strong (in pollen season) and disappeared (out of pollen season). For healthy controls the time point of sample taking will be correlated to the allergic rhinitis patients to have a similar pollen exposure. Nasal mucus will be sent for Liquid Chromatography Tandem mass spectrometry for proteomic analysis and from nasal epithelial cells RNA will be isolated and send for Microarray analysis. By an integrative omics approach gene and protein expression will be correlated and cross talk between nasal mucus and epithelium will be analysed. The identification of key genes or gene clusters leads to further identification of key proteins or protein groups as biomarkers that could serve for novel therapeutic or diagnostic strategies in allergic rhinitis. The integrative omic approach downsizes the potential candidates since the focus lies on epithelial gene expression and their protein products and excludes proteins that are highly abundant without direct correlation to allergen exposure e.g. through plasma exudation. Moreover, the genomic and proteomic analysis could explain in more detail how the barrier of mucus and epithelium are affected by allergen exposure. The comparison to healthy controls and the longitudinal changes throughout the season further sheds light on how these individuals react upon allergen exposure and how this could lead to prevention of sensitization.
