This prospective randomized double-blinded controlled study will be conducted to evaluate the effect of perioperative vitamin C on acute and chronic post mastectomy pain after breast cancer surgery
Chronic pain is a prevalent condition that negatively affects patients' quality of life. Implantable neurostimulation therapies have been proposed as a treatment option for chronic pain. However, real-world data on the effectiveness and safety of these therapies in Spain are scarce. This study aims to obtain real-world data on the effectiveness and safety of implantable stimulation systems for chronic pain treatment in Spain.
The goal of this clinical trial is to learn about hepatectomy on the prognosis of patients with nasopharyngeal carcinoma liver metastases (NCLM). The main questions it aims to answer are: To explore the effect of hepatectomy on the overall survival, recurrence-free survival and other prognostic indicators of patients with NCLM. To explore the impact of hepatectomy on the safety of patients with NCLM. Researchers will compare the prognosis of the patients in the hepatectomy group and the patients with NCLM who were prospectively enrolled in the same institution and received only systemic treatment at the same time by propensity score matching.
This study will be a prospective randomized study to evaluate the effect of tranexamic acid (TXA) use on intraoperative and postoperative outcomes among patients undergoing rhinoplasty by two Facial Plastic surgeons at Vanderbilt. Outcomes will include intra- and post-operative bleeding and postoperative bruising and swelling.
A study comparing atrioventricular junction ablation (AVJA) versus continued optimum medical rate control in patients with cardiac resynchronization therapy (CRT) and atrial fibrillation (AF) with suboptimal heart rate control on optimum medication.
- To compare the effect (heart rate and mean arterial pressure) of Ringer Lactate preloading and without preloading on induction dose requirement of Propofol. - The Propofol requirement for induction dose with respect to loss of eyelash reflex in Ringer Lactate preloaded versus control group.
The benefits of physical activity and adequate sleep are well documented, and their importance strengthens with the increasing prevalence of chronic diseases and multimorbidity. Interventions to promote physical activity and sleep that use commercial activity trackers may be useful non-pharmacological approaches to managing individual health; however, limited evidence exists on their use to improve physical activity in elderly patients with multimorbidity. This study aims to measure the effects of behavioral change techniques (BCTs) delivered by a wearable device on physical activity (PA) and quality of sleep (QS) in elderly patients with multimorbidity. The investigators designed an open-label randomized controlled trial with participants recruited through primary care and a specialist outpatient clinic. Participants must be more than 65 years old, have multimorbidity, and have access to smartphones. All eligible participants will receive PA promotion content and will be randomly assigned to wear a smartwatch. The primary outcome will be the participants' PA measurement at six months using the IPAQ-SF. Secondary outcomes will include changes in the participants' frailty status, biometric measurements, quality of life, and biopsychosocial assessments. A sample size of 40 participants per arm was calculated to detect group differences, with 50 participants recruited and randomized into each arm. This study aims to contribute to a better understanding of PA patterns and the impact of smartwatch-based PA interventions in patients with multimorbidity. The trial's findings are expected to improve our understanding of how physical activity patterns, patient-reported outcomes (PROMs), and healthcare resource utilization are linked in patients with multiple medical conditions. The study will use a registry for locally developed PROMs and data from the participants' medical records to determine how wearable data and medical information data can be used to predict PROMs and unplanned hospital admissions.
Uterine niche is a frequent condition in patients with a history of cesarean section. Many treatment methods have been described for repair of niche with varying effectivities. In conventional Laparoscopic approach, not all bleeding points and fibrotic area are resected, while conventional hysteroscopic one result in more wide defect with high risk of recurrence and cannot be used in large niche with low RMT. In this new Double approach (hysteroscopy and laparoscopy) technique, the benefit of both laparoscopy and hysteroscopy will be attained.
The goal of this experimental observation study is to figure out differently expressed biomarkers in lesion tissues in traumatic brain injury or hypertension intracranial hemorrhage patients. The main questions it aims to answer is: - Which RNA, protein and metabolites are differently expressed in lesion tissues? - What molecular mechanism is participated in TBI or ICH? Participants will be treated by emergency operation, and their lesion tissues will be collected during the operation.
The goal of this experimental observation study is to figure out differently expressed biomarkers in body fluid in traumatic brain injury patients. The main questions it aims to answer is: - Which RNA, protein and metabolites are differently expressed in lesion tissues? - What molecular mechanism is participated in TBI? Participants will be treated by emergency operation, and their body fluid samples will be collected in emergency room and during the operation.
