NCT03872271
Defunctioning ileostomy has demonstrated its benefits (rate and seriousness of anastomotic leakage) in cancer for low colorectal and coloanal anastomoses, whereas there are no such good quality evidences in case of ileal pouch-anal anastomosis (IPAA) performed for inflammatory bowel disease (IBD). However, most surgical teams do protect systematically IPAA by an ileostomy. Total proctocolectomy with IPAA is the gold standard for surgical management of ulcerative colitis (UC). This demanding procedure is often performed in 2 or 3 stages, namely subtotal colectomy, completion proctectomy with IPAA and defunctioning ileostomy closure. Subtotal colectomy with double stoma is first performed to allow nutritional support, reduce inflammation and stop immunosuppressive agents. Completion proctectomy with IPAA is then performed on a healthier patient. Hence, the need for a systematic defunctioning ileostomy is questioned. No study addressed specifically the question of completion proctectomy, whereas it concerns 36% to 42% of patients undergoing IPAA. Globally, the overall 6-month morbidity rate is 55% in case of stoma creation vs. 30% otherwise in IPAA. Moreover, defunctioning ileostomy has several drawbacks including an additional surgical procedure (stoma closure), a worse quality of life before closure, and the risk of dehydration that may require readmission. Following stoma closure, the risk of anastomotic leakage is around 4%. Overall, during the stoma period, 8% of patients will require reoperation. Finally, the risk of incisional hernia is 15-20% at the ex-ileostomy site. Therefore, the aim of this trial is to assess the need for a systematic defunctioning ileostomy after completion proctectomy with IPAA.
NCT04499157
Open-angle glaucoma is a degeneration of the optic nerve, highlighted by campimetric alterations, and wose only current therapeutic target is the lowering of the intra-ocular pressure (using eye drops, surgery or laser). MEMOPTIC is a tablet combining citicoline, magnesium and Gingko biloba, which have a neuroprotective effect already used in neurodegenerative diseases such as Alzheimer's disease for example. Citicoline has also shown several promising results in ophthalmological diseases (glaucoma, amblyopia or more recently in ischemic optic neuropathies). The citicoline used in eye drops (NEURODROP) has already shown results on the preservation of the vision of glaucomatous patients. The purpose of this project is to determine if MEMOPTIC can have an effect, in addition to the conventional treatments, in the preservation of vision of patients treated for an open-angle glaucoma.
NCT05103072
Patients with subthalamic nucleus have to go through a lot of examinations and tests, before and after surgery which is difficult, sometimes painful, for the patient. The investigators used to chose the best plot of the leads for stimulation by a procedure long and exhausting for the patient and the examinator. The investigators can chose the plot using a software (Guide Xt), which can delete the exhausting test. The investigators would like to study the non inferiority of this tool to choose the best plot .
NCT05717855
Evaluation of prenatal optic chiasm (OC) is important for the differential diagnosis of septo-optic dysplasia (SOD), which is a congenital optic disc anomaly, and the absence of the cavum septum pellucidum (CSP). Septo-optic dysplasia is associated with a wide range of neurological abnormalities, including hypoplasia of the visual pathways, CSP agenesis, and developmental delay.
NCT05715164
Pakistan is one of the most vulnerable low- and middle-income countries with 29 million adult active tobacco users. Smoking cessation services are lacking as the tobacco control initiatives have largely failed to address the smoking endemic. Over the last five years, Pakistan has witnessed the use of innovative tobacco harm reduction such as e-cigarettes, nicotine pouches, and non-nicotine replacement therapies (non-NRTs). However, their use remains limited. THR products are imported legally as consumer goods and are taxable. The lack of sufficient data for THR and its application is a challenge in gauging their effectiveness in assisting smokers to quit combustible smoking. Evidence-based studies on e-cigarettes and other nicotine products are required to gauge the effectiveness of e-cigarettes and nicotine pouches as smoking cessation aids. Keeping in view the study objectives, a sample size of 600 participants will be sufficient to assess the effectiveness of e-cigarettes and nicotine pouches for smoking cessation in Pakistan. Of these, 200 participants each will receive e-cigarettes and nicotine pouches along with basic care counseling, while the remaining 200 participants will only receive basic care counseling for 48 weeks. The association of participants' characteristics with smoking and health status will be based on bivariate and multivariate analysis. The simple t-test and variance analysis will assess the differences in intervention indicators between the control and treatment groups. For the inferential analysis, the average treatment impact of the treatments will find using quasi-experimental techniques such as difference in difference (DID) or Propensity Score Matching (PMS). This study will be evaluated participants at baseline, after their self-decided "quit date,". The follow-up will be a survey every 12 weeks. Results may inform the public, decision-makers, and researchers about the use of e-cigarettes and nicotine pouches helping smokers to quit smoking or switch to less harmful alternatives in the short- and medium-term periods.

NCT05124418
Periodontal plastic surgery is widely used to improve the esthetic and functional demands of patients. The palatal masticatory mucosa is the main donor area. A lot of methods to evaluate the thickness of palatal soft tissue were used. However, the methods published before were invasive or non-reproducible. Therefore, the aim of this study was to investigate the accuracy of the novel invasive method to evaluate the thickness of palatal masticatory mucosa thickness. Twelve periodontally healthy patients who will have CBCT on maxilla for implant surgery will be recruited in this study. Each patient will be measured at 15 points of palatal masticatory mucosa over canine to the second molar area, it will be done by a dynamic navigation system (test group) and periodontal probe piercing (control group). The data will be analyzed to evaluate the accuracy of dynamic navigation in the measurement of palatal masticatory mucosa thickness.
NCT05677620
This project evaluates the morphological predictive factors for prescribing a mandibular advancement device in the therapeutic approach of Obstructive sleep apnea (OSA). The investigators will carry out the project with patients who travel to CUF Tejo Hospital to solve their sleep disturbance, namely cases of obstructive sleep apnea. The investigators designed three groups of 22 individuals each. The investigators will only include individuals after signing the informed consent. In the 1st appointment, the principal investigator will conduct a complete anamnesis and a clinical examination, where several items will be documented: Age, gender, body mass index, mallampati index, neck, and waist circumference. The clinical interview will assess the patient's daytime sleepiness, nighttime snoring, and quality of life through the respective questionnaires: the Epworth Sleepiness Scale (ESS), the snoring severity scale (SSS), and the Sleep Apnea Quality of Life Index (SAQLI). Still, in the 1st consultation, a level III Polysomnography (PSG) will be prescribed to assess the possibility of OSA, and a pharyngeal computed tomography (CT) with cephalometric analysis and recording in maximum comfortable protrusion to evaluate the Upper Airway (UA) and the prognosis of mandibular advancement in case of UA collapse. The other group will perform Drug-Induced Sleep Endoscopy (DISE) and CT with registration in maximum comfortable protrusion. Then, the investigators will make personalized and titled mandibular advancement devices (MAD). The measurements and PSG III questionnaires will be carried out after 1 and 6 months to evaluate the results.

NCT05708651
The goal of this four-part preclinical \[I-II\] and clinical \[III-IV\] trial is to compare, with randomised crossover study design \[I-IV\], a new medical airway device with standard procedure (biteblock or no device) for upper airway patency during sedation with intravenous propofol \[I-IV\]. \- Page 1 of 9 \[DRAFT\] - The two main questions it aims to answer are if this new airway device is superior to standard procedure with respect to * maintenance of spontaneous ventilation \[I\] and upper airway volumes \[II\] at moderate and deep steady-state levels of sedation in healthy volunteer study participants, and * fewer and less lasting bedside signs of respiratory depression \[III-IV\], and less adjuvant use of manual airway support \[III-IV\] during procedural sedation (PS) according to standard of care(SOC) in study patients scheduled for colonoscopy or ureteral catheterisation under PS. Owing to the crossover study design used throughout the trial, there are no comparison groups of study participants \[I-II\] or study patients \[III-IV\].

The aim of this nationwide, observational cohort study is to evaluate current surveillance strategies after primary resection of pancreatic ductal adenocarcinoma (PDAC) in the Netherlands, with regard to the detection, treatment and survival of PDAC recurrence.
NCT03294720
The objective of this study is to evaluate the use of wrapping an ACL graft with a collagen matrix tissue wrap and injecting autologous bone marrow aspirate concentrate under the wrapping and into the graft. Investigators hypothesize that this method of augmenting ACL surgery will accelerate and improve the graft maturation and ligamentization process. Investigators propose to test this hypothesis with a series of cases of ACL reconstructions evaluated with post-operative MRI mapping sequences and validated clinical outcome measures
NCT04925739
Continuous positive airway pressure (CPAP) is the first-line treatment for obstructive sleep apnea syndrome (OSA). It consists of a pressure generator connected to a mask applied to the patient's face. CPAP treatment is restrictive, and nearly a quarter of patients abandon it over the long term. Various factors can influence adherence to CPAP therapy, including adverse events associated with the mask. However, it is clear that compliance with CPAP treatment, even if it has tended to improve over the last 30 years, is still sub-optimal. The "Air Liquide Medical Systems" company has developed a mask that aims to improve comfort and ease of use for the patient. This leaky nasal mask has a "silent" intentional leak port, which significantly reduces the noise caused by the escape of air. The noise associated with intentional leakage is one of the discomforts reported by patients and their spouses. In addition, this mask is equipped with a new generation headgear with adjustment indicators to assist the patient in fitting the mask. Optimal headgear fit is a prerequisite for comfort during treatment, as it reduces unintentional leakage. The main objective is to evaluate, through a questionnaire, the comfort and general appreciation of a nasal mask equipped with a silent leak system and a headgear with adjustment aids, of patients with OSA treated with CPAP. Secondary objectives are : 1. To evaluate the appearance of CPAP side effects related to the mask, 2. To collect the patient's appreciation of the mask headgear, 3. To evaluate the discomfort caused by the nasal obstruction reported by the patient, 4. To evaluate the daytime sleepiness of the patient, 5. To study the parameters of the CPAP treatment.
NCT05539898
A number of large randomized studies have demonstrated the importance of left ventricle ejection fraction (LV EF) for ventrucular tachyarhrythmia's (VT) prediction. The use of this indicator as the sole predictor of high arrhythmic risk requiring ICD implantation is enshrined in the current clinical recommendations. At the same time, many experts consider LV EF as too generalized indicator, which can be an integral indicator of total cardiovascular mortality, but lacks specificity in determining the risk of VT. It is known that only about 20% of patients with ICD implanted for primary prevention of sudden cardiac death (SCD) receive appropriate life-saving therapy. Purpose of the study: to develop additional criteria for selection of patients with heart failure for implantation of cardioverter-defibrillator for the purpose of primary SCD prevention on the basis of stratification of the risk of occurrence of stable ventricular tachyarrhythmias.
NCT05159726
This is a prospective, single-center, randomized control study to determine if video education at the time of postpartum discharge improves patient knowledge on the warning signs for the top three causes of severe maternal morbidity (infection, hemorrhage, and blood pressure disorders) in the first seven days following delivery. Participants will be randomized to written discharge education + video education (intervention) vs standard discharge education (control). They will complete a baseline questionnaire and a post-discharge education questionnaire during their postpartum stay to assess for knowledge improvement. The investigators hypothesize that video education will improve patient's knowledge of severe maternal morbidity warning signs.
NCT05088369
This will be a single centre, Phase 1, Placebo-controlled, Randomized, Doubleblind, SAD \& MAD Study to Assess the Safety, Tolerability and PK of HM201 in Healthy Subjects.
NCT04375462
Individuals with cancer causing an intestinal or stomach obstruction often require gastric drainage to prevent symptoms of nausea, vomiting, and to prevent aspiration. This is often achieved by a nasogastric (NG) tube, although prolonged NG tube use can lead to unwanted side effects like ulcers, bleeding, and they are generally uncomfortable. Gastric drainage through the use of a percutaneously placed endoscopic gastrostomy (PEG) tube has been used in people with cancer since the 1980s. This allows relief of symptoms of malignant bowel obstruction though venting of stomach contents. Decompressive PEG tubes are routinely used in individuals with malignant obstruction, although these tubes tend to get clogged from food blocking the tube. The AspireAssist is a weight loss device that allows participants to remove a large amount of the food in their stomachs after each meal to help them to lose weight via an aspiration device attached to the abdominal portion of the tube which allows instillation of water into the stomach, followed by aspiration of the gastric contents into a receptacle or the toilet. The device is placed endoscopically in an identical fashion to a standard PEG tube. Although most commonly used for weight loss, the device is FDA cleared to be used as a venting tube as well. The purpose of this study is to determine if the AspireAssist provides an improved quality of life when compared with a standard venting gastrostomy tube for participants with malignant bowel obstructions.
NCT05637138
The measurement of tcpCO2 has many disadvantages: the need for regular calibration (4 to 8 hours) of the sensor, the fact that the sensor heats the skin (risk of burns), the impossibility of measurement in ambulatory and the high cost of the monitor. In order to develop a new type of tcpCO2 sensor, it is necessary to acquire knowledge in fundamental physiology on the diffusion of CO2 through the skin.
NCT03148899
In human volunteers intranasal administration of oxytocin significantly increases parasympathetic and decreases sympathetic cardiac control. OSA is a very prevalent disease with high cardiovascular risk factors, yet this disease remains very poorly treated. This proposal, based on the current literature and new basic science results detailed above on the role of oxytocin in cardiovascular control, will test if oxytocin administration improves adverse cardiovascular events during the recurrent nocturnal apneas in patients with OSA. This project will lay the groundwork and provide preliminary data to obtain NIH funding to test this important hypotheses more thoroughly and in larger clinical trials. This study will explore if intranasal oxytocin has any positive cardiovascular benefits in patients with sleep apnea.
