This study explores the influence of the food matrix of seaweed-containing food products on iodine bioavailability. The investigation will ascertain whether iodine bioavailability (as a percentage of the dose ingested that is excreted in urine) is comparable between seaweed sheets, seaweed powder (in capsules), pizza fortified with powdered seaweed, and potassium iodide supplements.
The prevalence of Caesarean sections continues to increase around the world. In France, the proportion of Caesarean sections has doubled from 11% in 1981 to 20,2% in 2016, bringing with it an increase in the risk of obstetrical complications. Uterine defects, or Isthomcele, first defined by Morris in 1995 as a scarring abnormality with a dehiscence of the hysterotomy following a caesarean section. This purely iatrogenic pathology can cause inter-menstrual bleeding or pelvic pain. Several definitions of isthmosceles exist in scientific literature with variations according to the nature of the reference examination chosen and the measurements made. However, for the majority of authors, isthmoceles are characterized by a residual myometrial thickness of less than 3 millimetres in the sagittal plane. The prevalence of isthmoceles amoung patients with a unicicatricial uterus is about 61%. Currently, the main diagnostic technique for isthmoceles are 2D or 3D ultrasound and hysterosonography. Small, non-controlled studies have found that surgical treatment of the isthmocele is effective in reducing metrorrhagia. In these studies, the authors noted that patients with metrorrhagia were also more frequently affected by secondary infertility. A small number of non-comparative studies with a low level of evidence have looked into the efficacy of surgical treatment of isthmoceles on related symptoms: metrorraghia, pelvic pain and/or secondary infertility. Their results show an idiopathic secondary infertility rate in the presence of isthmoceles prior to surgical treatment of approximately 66%. Significantly higher pregnancy rates after treatment suggest that the surgical management of isthmoceles is worthwhile. However, these data suffer from not negligible selection bias. The initial findings concerning fertility after surgical repair seem promising and some teams propose systematic surgical management of the isthmocele before a technique of assisted reproduction (ART) although without any evidence in literature. Isthmocele surgery can result in uterine perforations, adhesions and intrauterine synechia known to be detrimental to future fertility. The efficacy of surgical management of surgey must therefore be demonstrated prior to any attempts at treatment. This will require large prospective studies based on a consensual definition of isthmocele. The diagnosis using Hysterosonography is currently considered as the "gold standard" examination. The main hypothesis of our study is that a significant isthmocele, defined by a residual myometrial thickness of less than 3mm, measured in the sagittal plane by hysterosonography, could alter the results of ART.
Decline in cognitive function after surgery occurs most commonly in older patients and patients undergoing major surgeries, such as heart surgery. Postoperative Cognitive Dysfunction (POCD) may last a prolonged period of time while Postoperative Delirium (POD) is a more acute disturbance in attention, awareness and cognition. The cause of POCD and POD are not fully understood, however some of the pathophysiology of POCD is similar to that of Alzheimer's disease (AD). Insulin given intravenously during heart surgery has been shown to preserve short and long-term memory function after the operation. Clinical trials further demonstrated that insulin given via the nose (intranasal) improves memory performance of patients with AD or cognitive impairment suggests that intranasal insulin also could be a therapeutic option for POCD and POD. This study is designed to examine the effect intranasal insulin on POCD and POD. The goal is to investigate whether administration of intranasal insulin during and after heart surgery improves cognitive function postoperatively.

Postcraniotomy headache (PCH) has been underestimated for the past decades. However, current treatments for PCH are either considered insufficient or accompanied by severe side-effects. Some studies revealed that peri-incisional injection of a mixed cocktail that contains ropivacaine, epinephrine, ketorolac, and methylprednisolone showed significant efficacy in relieving postoperative pain after total hip or knee arthroplasty. Previous literature reported that the cause of PCH was related to incision of the scalp and dura, which is considered similar to causes to postoperative pain after total hip or knee arthroplasty. Thus, investigators suppose that the cocktail mixture can better relieve PCH in adults.
This trial is a prospective randomized multicenter trial that assigns patients to either a treatment for Acute Respiratory Distress Syndrome (ARDS) with an Extracorporal Membrane Oxygenation (ECMO) immediately after admission to the intensive care unit or conservative treatment. The later can undergo ECMO following failure of conservative therapy as a rescue therapy. Patients will be included within 96h of the onset of symptoms of ARDS and will be randomized according to standard procedure. Follow-up will be performed until hospital discharge.
Autologous Platelet-Rich-Plasma (PRP) represents a regenerative therapy that has gained remarkable ground in the field of orthopaedics in recent years. PRP has been implemented for a plethora of musculoskeletal ailments, being associated with minor complications and noteworthy efficacy (Akeda et al., 2019). PRP has been depicted to contain a variety of growth factors crucial for regulation of cell proliferation and migration as well as extracellular matrix synthesis (Cheng et al., 2019). Furthermore, therapeutic effect of PRP administration is considered to be additionally exerted via its anti-inflammatory and immunoregulative properties, as it has been delineated to induce regional decrease of pro-inflammatory mediators at the injection site (Hirase et al., 2020). Lumbar Degenerative Disc Disease (DDD) and Facet Joint Syndrome (FJS) constitute chronic degenerative conditions of lumbar spine that have been associated with substantial morbidity and disability in recent years. Besides the noted progress in comprehension of these conditions' pathogenesis, available therapeutic modalities remain extremely limited and controversial, being not capable of altering the natural progress of underlying disease (Wu et al., 2016; Wu et al., 2017; Hirase et al., 2020). Autologous PRR has been recommended as a beneficial alternative instead of conventional treatment strategies for interventional management of lumbar DDD and FJS (Aufiero et al., 2015; Navani and Hames, 2015; Kirchner and Anitua, 2016; Levi et al., 2016; Tuakli-Wosornu et al., 2016; Wu et al., 2016; Akeda et al., 2017; Lutz GE, 2017; Wu et al., 2017; Cheng et al., 2019). Results of these studies indicated that intra-discal and intra-articular injection of PRP for DDD and FJS respectively is characterized by safety and satisfactory efficacy in reducing intensity of clinical manifestations, exerting also potentially regenerative effects. However, quality of available evidence is remarkably low, since in the overwhelming majority of these studies was a limited number of patients evaluated. Furthermore, determined follow-up intervals were not extended and, most importantly, patients were not majorly with rigorous clinical and radiologic criteria selected. Aim of this study is to investigate the precise effects of intradiscal and intra-articular injection of PRP in patients with early-stage lumbar DDD and FJS, as determined by particular radiologic classifications. The prospective design, the defined greater number of recruited individuals in pilot analysis as well as the comparatively greater follow-up underline the originality of our protocol.
The objective of the randomized controlled study is to compare combination of sublingual misoprostol and routine uterotonics versus routine uterotonics alone on PPH in low risk women after vaginal delivery. The hypothesis is that combination of sublingual misoprostol and routine uterotonics is more effective than routine uterotonics alone in reduction of PPH in low risk women after vaginal delivery.
The primary objective of the research is to study the relation between the presence and /or the anti SARS-Co-V-2 IgM level in an early stage of COVID-19 infection, and the evolution of the illness.
Background: There is consistent evidence that community and clinical samples of individuals with an alcohol use disorder (AUD) have attentional biases toward alcohol cues. The alcohol attentional control training program (AACTP) has shown promise for retraining these biases and decreasing alcohol consumption in community samples of excessive drinkers. However, there is a lack of evidence regarding the effectiveness of ACTP in clinical AUD samples. The main aim of the present study is to investigate whether primary pharmacological and psychological, evidence-based alcohol treatment can be enhanced by the addition of a gamified AACTP smartphone application for patients with an AUD. Design and methods: The study will be implemented as a randomized controlled trial. A total of 317 consecutively enrolled patients with AUD will be recruited from alcohol outpatient clinics in Denmark. Patients will be randomized to one of three groups upon initiation of primary alcohol treatment: Group A: a gamified AACTP smartphone application + treatment as usual (TAU); Group B: a gamified AACTP sham-control application + TAU; or Group C: only TAU. Treatment outcomes will be assessed at baseline, post-treatment, and at 3- and 6-month follow-ups. Repeated measures MANOVA will be used to compare the trajectories of the groups over time on alcohol attentional bias, alcohol craving, and drinking reductions. It is hypothesized that Group A will achieve better treatment outcomes than either Group B or Group C. Perspectives: Because attentional bias for alcohol cues is proportional to the amount of alcohol consumed, and these biases are not addressed within current evidence-based treatment programs, this study is expected to provide new evidence regarding the effectiveness of the gamified AACTP in a clinical population. Furthermore, due to promising results found using AACTP in community samples of excessive drinkers, there is a high probability that the AACTP treatment in this study will also be effective, thereby allowing AACTP to be readily implemented in clinical settings. Finally, it is expected that this study will increase the effectiveness of evidence-based AUD treatment and introduce a new, low-cost gamified treatment targeting patients with an AUD. Overall, this study is likely to have an impact at the scientific, clinical, and societal levels.
