In France, the incidence of congenital hypothyroidism has increased significantly since the newborn screening program was introduced in 1978. The largest increase is seen in children with eutopic thyroid gland. More than one-third of children with eutopic gland have transient hypothyroidism. Clinical practice guidelines recommend to re-evaluate thyroid function in children with eutopic gland around the age of 3 years to determine whether hypothyroidism is transient or permanent. Up until today it is still difficult to determine early on whether hypothyroidism is transient or permanent in children with eutopic gland. Our aim is to identify one or more predictive factors for transient congenital hypothyroidism in children with eutopic gland or thyroid hemiagenesis.

The population over 65 years of age will be increasingly exposed to surgical procedures that require general anesthesia. Postoperative delirium is one of the main causes of preventable postoperative morbidity in the elderly population and is a frequent event after cardiac surgery with extracorporeal circulation. The excess administration of anesthetics that potentiate the Gamma Aminobutyric A receptor, such as propofol, are related to an intraoperative electroencephalographic pattern called burst suppression that has been associated with postoperative delirium. It is unknown whether this pattern is secondary to a relative overdose of anesthetics or rather corresponds to a characteristic of a vulnerable brain that is suppressed at doses at which other patients are not. Our objective will be to determine whether burst suppression in people over 65 years of age during a standardized anesthetic induction with propofol for cardiac surgery with extracorporeal circulation is associated with postoperative delirium compared to older people who do not present it.

This is a sub-study nested into the existing NICHD Global Network for Women's & Children's Health Research Maternal Newborn Health (MNH) registry that is a prospective, observational population-based registry in Eastern Maharashtra, India. This study will assess the prevalence of iron deficiency anemia (IDA) and non-iron deficiency anemia (NIDA) in Eastern Maharashtra and will assess the association between both conditions and neo-natal and infant health outcomes (birth weight, gestational age at birth, weight-for-gestational-age z-score and infant hemoglobin concentration at 6 weeks). The investigators will also assess the relative strength of the association between anemia in the 1st trimester and 3rd trimester (after iron needs have increased but mothers may have been taking iron folic acid (IFA) supplements for several months) and infant health outcomes.

Anti-neutrophil cytoplasm antibodies (ANCA) are defined as important serological markers for the diagnosis of some forms of small vessel vasculitis, including granulomatosis with polyangiitis (GPA) , microscopic polyangiitis(MPA) and to a lesser extent Churg -Strauss syndrome or Eosinophilic granulomatosis with polyangiitis (EGPA).So they are called ANCA-associated vasculitis(AAV). An international consensus statement for ANCA testing statement was issued in 2017 and states that the antigen specific immunoassays can be used for the accurate diagnosis of ANCA-associated vasculitis without the need for indirect immunofluorescence(IIF). In the present study we will test whether the antigen specific assays screening is a valuable alternative to IIF confirming with immunoassay for the diagnosis of AAV on a number of patients and controls. Aim To evaluate the performance of the recommended strategy for the detection of ANCA based on screening with antigen specific immunoassays on a number of AAV patients and relevant disease controls In Kagawa university hospital (rheumatology department). Patients and methods This is a prospective study will be conducted at the department of rheumatology in Kagawa university hospital in which consecutive samples will be included from patients suspected to have AAV; patients subsequently identified as having AAV will be included as AAV patients, while patients in which the diagnosis AAV is rejected, will be included as disease controls. PR3-and MPO-ANCA will be performed using assays from Medical & Biological Laboratories Co (Anchor CLEIA) isayama.takuya@mbl.co.jp

Posterior vitreous detachment is a common event. With optical coherence tomography, the investigators can precisely follow the stage of posterior vitrous detachment. In this study, the investigators investigate if the loss of contact between the vitreous and the fovea is the start of glaucoma progression.

--- Background and study aim Atrial fibrillation (AF) is an irregular heart rhythm which causes a five-fold increase in the risk of stroke. Approximately one in ten people aged over 70 have AF. If AF is recognised then the risk of stroke can be reduced by taking tablets regularly. AF can be difficult to recognise as it can occur without symptoms and only intermittently. Consequently, AF is not recognised in many people, meaning they live with an increased risk of stroke. Therefore, it is important to find ways to identify AF more reliably. Recently, wearable devices have been developed which could be useful for identifying AF. Several devices can monitor heart activity in daily life, including wristbands, smart watches and chest patch monitors. The aim of this study is to assess the acceptability and performance of wearables for use in AF screening in older adults. The primary objective is to determine the feasibility of measuring inter-beat-intervals using a wristband. The secondary objectives are: (i) to determine the acceptability of wearables; (ii) to determine the acceptability of the screening approach; (iii) to assess the performance of wearables for acquiring signals; (iv) to assess the performance of signal processing algorithms; and (v) to assess the performance of wearables for AF screening. --- Who can participate? Selected people who have previously participated in the SAFER Programme can participate in this study. The Investigators will invite previous SAFER Programme participants to also participate in this study, aiming to enrol 65 without AF, and 65 with AF. --- What does the study involve? Participants will be asked to wear three devices for seven days: Two wristbands (like watches), and one chest patch (like a plaster). These devices will collect measurements of their heart's activity. The Investigators will also ask participants to tell them how they found wearing the devices by completing a questionnaire. The Investigators will compare how participants found wearing each device, and how accurately each device identifies AF. --- What are the possible benefits and risks of participating? There will be no direct benefit to participants, although this research is intended to benefit future patients like them. Some participants may experience irritation or redness whilst wearing a chest patch - participants will be advised that if this occurs then they should remove it straightaway.

The aim of this study is to assess the changes in retinal nerve fiber layer due to SSRI treatment in first-attack major depressive patients.

The investigators evaluate the response of rectal cancer to neoadjuvant therapy and classify the response according to specific periods of time after the end of neoadjuvant treatment.

Bowel cancer is the 3rd most common cancer in males and females. Most bowel cancers develop from precancerous polyps in the bowel. Colonoscopy can detect and remove these polyps, thereby reducing the risk of developing bowel cancer. However, colonoscopy is an invasive procedure with inherent risk, and can be both uncomfortable and embarrassing to undergo. The risks and numerous other barriers often mean colonoscopy, and cancer preventing polyp removal, is not performed. The investigators aim to start the first in-human feasibility clinical investigation of a robotic magnetic colonoscope in 2021. The new device aims to reduce the discomfort and risk associated with colonoscopy. As part of the patient and end user involvement aspect of the project the investigators aim to perform a mixed methodology inductive type research project exploring experiences of colonoscopy for patient and endoscopists. The study will follow an exploratory mixed methodology format with two parallel work-streams for patients and endoscopists. Each work-stream will consisting of a focus groups (1-2 for each patients and endoscopists), followed by 20 endoscopist and 30 patient in-depth interviews, then an online questionnaire. Each stage will be thematically analysed to form the semi-structured questions for the next stage. The target population will be endoscopists who perform colonoscopy and people who have undergone, or refused to undergo, a colonoscopy. Focus groups will be performed in groups of 6-10 participants, and both interview and focus groups will be performed via video/teleconferencing.

In our study, we aimed to compare the average length of stay, death rates and costs of intensive care patients in October-November-December 2019 (before COVID 19) and October-November-December 2020 (during COVID 19).
