This project aims to explore how social media use, in particular food photography, influences eating behaviours. It will be approached through three methods - a correlational experience sampling method, an experimental experience sampling method, and an experimental laboratory method. This registration describes the correlational experience sampling method.

Secondary bacterial influenza pneumonia caused by Panton-Valentine Leukocidin Positive Staphylococcus aureus is a rare complication but with poor prognosis. This pathology seems to affect young patients (20-40 years) without any medical history. Since the influenza pandemic of 2009, this complication is more and more mentioned, sought and diagnosed. However, the literature is poor, consisting of case reports, experimental studies on murine models, and low-power studies. The main objective is to evaluate the mortality in intensive care units of patients post-influenza bacterial pneumonia due to a Panton-Valentine Leukocidin positive Staphylococcus aureus

Endoscopic Submucosal Dissection (ESD) is currently the main method of treatment of early esophageal cancer and precancerous lesions. Therefore, the investigators are looking forward to conduct a cohort study on early esophageal cancer patients undergoing endoscopic treatment collected from Zhongshan Hospital, Fudan University, comparing the WHO standard with Japanese standard of endoscopic therapy diagnosis. In addition，the investigators will collect patients' detailed informations and analyze the risk factors for metastasis and recurrence of early esophageal cancer.

This is a psychosocial screening application to usual care in a cohort of neuroendocrine tumor patients. The application involves monitoring using the NCCN Distress Thermometer(DT), Hospital Anxiety and Depression Scale(HADS), Self-Perceived Burden Scale(SPBS) and Connor-Davidson Resilience Scale(CD-RISC). These assessments will be completed at baseline, 3 months, 6 months, 12 months and 24 months. Patients will have the option of filling out questionnaires more frequently if desired.

This is a cross-sectional cohort study which aims to compare the invasive and non-invasive assessments on aortic blood pressure and cardiac funtion in subjects without history of cardio-vascular disease. Left ventricular (LV) filling pressure, LV volume, and aortic blood pressure will be measured invasively. Non-invasive assessment includes echocardiography,aortic, and carotid blood pressure measurement.

Introduction: Taxinomisis trial is part of the Taxinomisis project. The concept of the Taxinomisis project is to stratify carotid artery disease relying on new modern data corresponding to contemporary patients based on information from longitudinal studies. Taxinomisis trial will validate this tool and adjust such stratification. Initial step of the project is characterization of symptomatic and asymptomatic carotid atherosclerotic plaque lesions, identification of risk and susceptibility factors through the exploitation of longitudinal cohort data and multiomics and disintegration of carotid artery disease phenotypes into endotypes through joint modeling of multipleomics data sets and systems medicine approaches. Finally such stratification model will be validated and adjusted in the Taxinomisis clinical trial.

To evaluate whether the use of the Argus II retinal prosthesis improves the confidence and self-esteem of patients with advanced retinopathy pigmentosa

Rugby union is a high intensity, intermittent team sport which is played over 80 minutes. Players are divided into two main positional groups, forwards and backs, with backs covering a larger distance and completing more sprints and forwards partaking in more static exertions. With the game of rugby union getting progressively faster, body composition and power to weight ratio are key determinants. Due to the demands placed on these players it is essential that they are in optimal health continually, however, whilst the required physical attributes are well documented, this research will provide an insight into physiological and anthropometric changes that occur across two seasons. During this study subjects will be asked to attend the lab on 8 occasions over the course of two seasons (June 2018, September 2018, January 2019, April 2019, June 2019, September 2019, January 2020 and April 2020). During these visits the following tests will be completed; a peripheral Quantitative Computed Tomography (pQCT) scan of the bone mineral composition of the tibia and radius, total body composition via Dual Energy X-ray Absorptiometry (DXA), anterior-posterior spine bone mineral density to assess fracture risk via DXA, vertebral fracture risk via DXA. ~24ml of whole blood will be taken to determine serum 25(OH)D, albumin, calcium, zinc, total red blood cell count, lymphocytes, monocytes, carboxy-terminal collagen crosslinks (CTX) and amino-terminal propeptide (P1NP) concentrations. In June all players will complete a 6 minute run to determine fitness. Players will be expected to measure body weight and complete wellness questionnaires daily at the club and have skinfold measurements taken monthly. global positioning system (GPS) data will be collected during each training session and performance analysis will be utilised to determine the amount of contacts completed. Illness and injury occurrences will be recorded throughout the season.

Urodynamic examination evaluates storage and empting phases of the urinary bladder. It enables the clinician to correlate physiologic findings to patients' complains. The data gathered during the examination divided to storage and empting. During the storage phase, bladder sensation is measured while the bladder is filled with sterile water. During years of practice, we noticed that early sensation (bladder over-sensitivity) is occasionally associated with bladder outlet obstruction (as demonstrated in the emptying phase of the examination.

Induction of labor is a common obstetric procedure that is routinely performed worldwide. However, when cervical conditions are not favorable (bishop <6), induction of labor is preceded by cervical ripening, usually with prostaglandins. The method of ripening most commonly used in France (89% of maternity wards) is the dinoprostone vaginal insert. In the majority of hospitals in France, dinoprostone vaginal inserts are usually placed in the morning, because of the higher availability of personnel (midwives and nurses). However, morning placement might increase the likelihood of the delivery occurring at night, since the mean interval between the insert placement and delivery is about 13 to 20 hours. Many studies have now shown that the risk of obstetrical complications, as well as neonatal morbidity and mortality is increased when deliveries occur at night. Several factors have been suggested behind the increased morbidity at night, including the lower number of personnel working, the fatigue associated with night work and the disruption of the circadian rhythm, and the insufficient supervision of residents. Very few studies have evaluated the importance of the timing of placement of the intravaginal dinoprostone insert, and its influence on the occurrence of night deliveries. Some investigators have recently performed a retrospective study at Angers university hospital that assessed the time interval between placing the dinoprostone vaginal insert and delivery, as well as the factors impacting the time to delivery, and found that nulliparity, obesity, a closed cervix on initial examination, and intact membranes at the time of insertion increased the time to delivery. Moreover, the investigators proposed a regression equation that allows to calculate the mean time from insert placement to delivery for each patient, and have decided to incorporate it in the routine practice. The investigators have decided to analyze the validity of the mathematical model. The consequence would be, thanks to a personalized timing for placement of dinoprostone vaginal insert based on every patient's characteristics (parity, BMI, cervical dilation and state of membranes), a decreased number of deliveries occurring between 12 p.m. and 6 a.m.
