NCT02584283
Rationale: Recent publications report good results of controlled donation after circulatory death (DCD) Maastricht category III liver transplantation when strict donor-recipient matching is applied and ischemia times are kept to a minimum. However a major concern remains the high rate of biliary complications after transplantation of DCD livers. Non-anastomotic biliary strictures (NAS) occur in 29% of patients receiving a DCD graft whereas the incidence of NAS in recipients of donation after brain death (DBD) liver grafts is 11%. NAS are associated with higher morbidity and increased cost of liver transplantation. Injury to the biliary epithelium and the peribiliary vascular plexus occurring during donor warm ischemia and static cold storage (SCS) has been identified as a major risk factor for development of NAS. Machine perfusion has been proposed as an alternative strategy for organ preservation, offering the opportunity to improve the quality of the organ by providing oxygen to the graft. Experimental studies have shown that end-ischemic dual hypothermic oxygenated machine perfusion (DHOPE) helps liver grafts to recover from ischemia by restoring mitochondrial function. Moreover, DHOPE has been shown to provide better preservation of peribiliary vascular plexus of the bile ducts, which could be an important step forward in reducing the incidence of NAS after transplantation. Objective: To study the efficacy of end-ischemic DHOPE in reducing the incidence of NAS within six months after controlled DCD (Maastricht category III) liver transplantation. Study design: An international, multicenter, prospective, randomized, controlled, interventional, clinical trial with a two parallel arm approach (treatment/control). Study population: Adult patients (≥18 yrs old) undergoing a liver transplantation with a liver graft procured from a controlled DCD donor (Maastricht category III) with a body weight ≥40 kg. Intervention: In the intervention group liver grafts will be subjected to two hours of hypothermic, oxygenated perfusion at the end of SCS and before implantation. In the control group donor liver grafts will be preserved in accordance to standard practice by SCS only. Main study parameters/endpoints: The incidence and severity of symptomatic NAS as diagnosed by an Adjudication committee (who are blinded for the group assignment) by means of magnetic resonance cholangiopancreatography (MRCP).

NCT04572282
With the growing number of cancer survivors, challenges to deal with comorbidities and impacted quality of life of cancer survivors by the disease and treatments also surge. Symptoms and Adverse Events are common and insufficiently monitored in real time / real life, which leads to increased symptom burden, treatment delays and unplanned hospital admissions. Remote monitoring apps have been shown to improve quality of life, symptom control and survival in published clinical trials, but no data with such interventions exists on the Portuguese population. We will conduct a pilot study to explore the feasibility of a mobile app for remote symptom monitoring in cancer patients. Patients will be recruited in Portuguese hospitals and will be invited to test the app for one month. Patient experience and satisfaction will be assessed via a weekly survey. The results of this pilot study will inform subsequent randomized clinical trials to test safety and efficacy of remote monitoring and lifestyle interventions to improve symptoms control and quality of life.
NCT04540237
Granulomatous mastitis is a rare, chronic, benign inflammatory disease of the breast that plays a role in many varying etiologies, including infectious and non-infectious causes. Etiological reasons were examined in various studies, but neither etiology nor definite criteria for diagnosis were found. Our aim in this study is to examine the role of cytokines in differentiating the etiology of granulomatous mastitis and using it as a prognostic marker.
NCT02770274
To compare the safety and effectiveness of dual anti-platelet therapy with cilostazol 100 mg twice daily and aspirin 100 mg daily versus monotherapy with aspirin 100 mg daily in patients undergoing peripheral angioplasty or stenting or both for the management of peripheral arterial disease.
NCT04705584
Spring catarrh is a prevalent type of conjunctival allergic disorder in temperate countries. Topical steroids are the cornerstone management of spring catarrh beside other anti allergic drugs. However, prolonged use of topical steroids especqially in resistant spring catarrh carries risk of ocular side effects as 2nd glaucoma and cataract. We will investigate the safety and efficacy of topical immuonosuppressant in the management of resistant spring catarrh as an alternative to steroid therapy.

NCT04703088
Spinal anesthesia is the preferred technique for elective cesarean section as per ASA guidelines. Hypotension is the main complication of this technique and is secondary to both sympatholysis and its associated decrease in systemic vascular resistance and to the Bezold-Jarisch reflex, which causes hypotension and bradycardia in response to noxious stimuli detected in the cardiac ventricles. In pregnant patients, spinal anesthesia induced hypotension is worsened by compression of the aorta and inferior vena cava by the gravid uterus. In this setting, hypotension could lead to uteroplacental hypoperfusion and fetal distress. In its 2020 guidelines for enhanced recovery after cesarean section, SOAP states that preventing spinal-induced hypotension is an important strategy to enhance maternal and neonatal outcomes in cesarean delivery Recent studies showed that 5-hydroxytryptamine-3 receptor antagonists, mostly used as nausea and vomiting prophylaxis agents, also contributed to inhibit the Bezold-Jarisch reflex and its associated hemodynamic consequences. Ondansetron is the most studied molecule in this field. Many recent studies and meta-analyses show renewed interest in the use of norepinephrine as a first line agent for preventing and treating spinal anesthesia-induced hypotension in obstetric anesthesia practice instead of phenylephrine. Norepinephrine has the advantage of a better cardiac output and cardiac frequency as compared to phenylephrine without any fetal side effect. The combination of ondansetron and phenylephrine for the prevention of spinal anesthesia-induced hypotension has been studied, but not the combination of ondansetron and norepinephrine. The main objective of this study is to evaluate the sparing effect of a standard dose of ondansetron on norepinephrine consumption during elective cesarean section under spinal anesthesia by determining the effective dose in 50% of subjects (ED50) of a prophylactic norepinephrine infusion after receiving a single dose of 4 mg of ondansetron or a saline control.

NCT03391830
To evaluate the benefit for statin use in prevention of of CI-AKI after computed tomography urogram (CTU).
NCT03089047
To compare the physiologic benefits of rejuvenated RBCs (rejRBCs) to standards RBCs (PRBCs), we will emulate critical conditions by safely maximizing stress on the cardiovascular system, in an elective, feasible volunteer study. Maximal oxygen uptake (VO2max) will be measured in an anemic, post-donation, pre-transfusion state, and also after transfusing 14-day-old, autologous blood randomized to standard storage or standard storage with rejuvenation. We hypothesize that transfusion of standard PRBCs is less effective at increasing oxygen delivery (measured by VO2max) compared with transfusion of rejRBCs.
NCT04703465
Liver transplantation is currently the only effective way to treat end-stage liver disease.The shortage of donor liver is still the major problem. Incidence of HBcAb+ varies between different regions. The HBcAb positive rate could be as high as 52% in China.HBcAb positive donor liver may enlarge donor pool and thus save ESLD patients. However, the use of HBcAb positive donor liver may induce HBV infection in hepatitis B negative recipient after liver transplantation. Tenofovir alafenamide (TAF) has better stability in plasma and higher liver targeting property in comparison with tenofovir (TDF), with an extra amide bond, which allows strong antiviral effect with much less doses and reducing the renal and bone injury. Our study intends to evaluate the efficacy and safety of HBV prophylaxis treatment of TAF in HBV negative patients after receiving HBcAb positive donor livers.

In recent years, media attention has focused on the long-term sequelae of repeated concussive episodes in professional athletes. The growing understanding of the damage done by what was once considered a "ding" during a game or match, and the neurologic consequences of "playing through" or returning to play too soon has led to additional interest in and concern for pediatric athletes (18 or under) who experience sports-related concussions during game or practice play. Because it has only been in recent years that the full scope of damage done by repeated concussive episodes has come to light, very little research has been done on treatment of concussion in either adults or children. Brain injuries in children can be especially problematic, as the brain may continue to develop until the child reaches the age of 24 or older, so concussion during this time of development may be particularly damaging. Docosahexaenoic acid (DHA) is an omega-3 fatty acid commonly found in both fish oils and algae. DHA is known to improve development of the eyes and brain in young children. It is thought to be an effective anti-inflammatory and anti-oxidant, and since it occurs naturally and causes very few harmful side effects, it may be a useful compound in the treatment of pediatric concussion. This is a feasibility trial of DHA for the treatment of sports concussion in a pediatric population. The investigators' primary aim is to determine acceptability of randomization for this compound as well as rate of enrollment given our clinical population. The investigators' secondary aim is to examine preliminary outcomes. The investigators hypothesize that subjects who take 2 g of DHA daily for 3 months will see a shorter time to full recovery and return to play and a shorter time to resolve balance disturbance. These are good, albeit unvalidated, clinical indicators of concussive recovery.

NCT04047849
This study is a non-blinded, prospective, randomized controlled trial designed to compare the effect of outpatient oral antibiotics (i.e., amoxicillin and azithromycin) on the length of time (days) that pregnancy continues after a patient's water bag has ruptured prematurely. If a patient has been diagnosed with rupture of their water bag between 18 0/7 weeks and 22 6/7 weeks and there are no other associated complications with the pregnancy, the patient is eligible for initial consideration for this study. Patients will be admitted to the hospital for a 24-hour monitoring period. If the patient remains without further complications during this monitoring period, the patient will be eligible for enrollment. If enrollment is desired, the patient will be randomly assigned to receive either antibiotics (treatment arm of the study) or no antibiotics (control arm of the study). The treatment arm will receive an outpatient, 7-day course of oral antibiotics (azithromycin and amoxicillin) with the first dose given in the hospital to ensure no side effects. The control arm will not receive outpatient antibiotics. Both groups will have weekly, office follow-up visits with high-risk pregnancy specialists to ensure no further complications. Both groups will be admitted to the hospital if the patients reach 23 0/7 weeks without complications. At this time the patients will receive all medications and therapies recommended by the governing board of OBGYNs. Subjects of both groups will also be admitted before 23 0/7 weeks if further complications noted either at their clinic follow up visits or anytime outside of the hospital. The duration of time that the patient remains pregnant after breaking of the water bag will be compared in each group. The investigators will also see if there is a difference in the number of patients able to reach 23 0/7 weeks between each group (treatment versus control).
NCT02364167
The study entitled "Acupuncture vs. placebo acupuncture and vs. standard therapy for pain control after elective caesarian section - a randomized controlled trial" aims to investigate whether acupuncture with indwelling fixed needles reduces pain and analgesic requirement as compared to placebo and standard therapy in patients after after elective caesarian section (CS) in the period from January 2015 to May 2016. For that purpose 180 adult patients scheduled to elective elective CS in spinal anesthesia will be recruited according to eligibility criteria. 120 patients will be randomized either to verum or placebo acupuncture, 60 patients will be included in non-randomized "standard therapy" arm. The outcome measures are: postoperative analgesic requirement, pain intensity, incidence of side effects and physiological parameters.
