Filter by:Hirschsprung disease (HSCR) is characterized by the absence of ganglion cells (aganglionosis) in the distal bowel extending proximally for varying distances that results in persistent spasm in the affected bowel and functional intestinal obstruction. Patients can be classified as rectosigmoid HSCR when aganglionosis confined to the rectosigmoid and long-segment or total colonic HSCR when aganglionosis extends beyond the upper sigmoid. Aganglionosis of long-segment HSCR can extend to the descending colon, transverse colon, ascending colon, but not to the terminal ileum. To date, there is insufficient evidence to recommend a preferred or superior method for the surgical repair for long-segment HSCR. In general, a pull-through with standard of care for the intestine and mesentery, which avoids excessive resection of the colon and coloanal reconstruction, is performed for long-segment HSCR.There are reports that a significant percentage of long-segment HSCR patients continue to have difficulty with soiling and incontinence,however there were also reports long-segment HSCR patients have the same continece as rectosigmoid HSCR.The outcome of long-segment HSCR should be thoroughly evaluated. The present study was designed to evaluate the long-term outcomes of long-segment HSCR.
The investigators perform a retro-prospective exploratory cohort study among patients 65 to 85 years old with pre-operative head MRI result after thoracic surgery in Renji Hospital Affiliated to Shanghai Jiaotong University from November 2020 to December 2021. Perioperative data were collected, including preoperative general condition, laboratory examination, auxiliary examination (blood routine, blood coagulation, liver and kidney function, etc.), perioperative indicators （use of anesthetics, anesthetic time, blood pressure, etc.）, postoperative cerebral function follow-up and occurrence of cerebral vascular complications (brain infarction, brain bleed, etc.) of patients.
Anaesthetic depth and complications after major surgery: an international, randomised controlled trial - The BALANCED trial. In this large, international, randomised controlled trial that enrolled patients aged 60 years and over with significant comorbidity and at increased risk of complications after major surgery, we found no evidence that light general anaesthesia (bispectral index 50) was superior to deep general anaesthesia (bispectral index 35) in reducing 1-year mortality. The BALANCED long term follow up study will look at whether depth of anesthesia affects long term (beyond 1 year) survival. The primary hypothesis is that targetting BIS 50 will result in superior long term survival compared to targetting BIS 35. The two secondary hypotheses are that BIS titration to BIS 50 will 1. reduce local cancer recurrence or metastatic spread and consequently improve long-term survival 2. reduce postoperative delirium and associated cognitive impairment and consequently improve long-term survival Both these mechanisms would be expected to take longer to manifest as reduced survival than 1-year all-cause mortality primary outcome in the Balanced trial. Trials of cancer outcomes often use 5-year survival or similar timeframes to determine evidence of clinical benefit. A steeper cognitive trajectory due to intermediate outcomes such as delirium and cognitive impairment may take longer than 1 year to produce a clinically important difference in survival 30. The 10.6% relative risk reduction seen in the Balanced trial could translate to a statistically and clinically meaningful survival difference in this high-risk population. This population may have 5-year survival of ~80% translating to an absolute survival difference of ~2% potentially (if the ~10% RRR is maintained beyond 1 year). The alternative is that there is no long-term mortality difference which would provide continuing clinical guidance of the safety of current practice in patients who are not at high risk of delirium. This study could provide a rationale for trials in larger populations (such as the total Balanced trial population) or targeted subgroups such as cancer and delirium to provide further mechanistic insights. Long-term survival is an important patient-centred outcome. The mechanisms described above may manifest in longer-term outcomes providing a clear rationale for the current trial.
The omega gastric bypass (OAGB) is developing worldwide as an alternative to the Y gastric bypass (RYGB). Cases of nutrition deficiency after OAGB, in particular protein deficency, are regularly reported in the literature, raising the question of the medium/long-term safety of this procedure. In its technology assessment report issued in September 2019 (HAS, 2019), the Haute Autorité de Santé rules on the invalidity of OAGB with a 200 cm biliary limb and the lack of sufficient data on the safety of OAGB with a 150 cm biliary limb compared to RYGB. The lack of long-term data on weight, resolution of comorbidities, quality of life, and endoscopic evaluation given the risk of lower esophageal cancer is also noted. The main objective of the study is to compare the incidence of serious adverse events related to surgery after OAGB at 10 years, according to 2 types of loop: a realization with a 150-cm biliary loop (OAGB AB150) versus a realization with a 200-cm biliary loop (OAGB AB200).
Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a disease caused by allo-immunisation during pregnancy. If left untreated, FNAIT can lead to severe fetal intracranial haemorrhage. This complication can be prevented by weekly administration of intravenous immunoglobulin (IVIg) to the mother during pregnancy. Knowledge on long-term development of FNAIT survivors with or without IVIg treatment is very limited but an important subject in the counselling of parents of newly diagnosed cases. To evaluate the long-term neurodevelopmental outcome in two groups of children with FNAIT will be asked to participate in our study in an outpatient clinic setting.
A prospective study for long-term follow-up (LTFU) to evaluate safety and efficacy in subjects who participated in the Phase 1/2 randomized placebo-controlled trial MESRIX.
This study involves individuals who are currently participating in the Wounded Warrior Recovery Project and underwent aeromedical evacuation (AE) due to injury during deployment in Iraq or Afghanistan. The goal of the study is to understand how best to engage wounded warriors in research activities studying long-term health. Based on the results from this study, the investigators can plan a larger study with the goal to better understand the long-term health conditions of individuals who were injured in combat and improve patient care. As part of the study, participants will be asked to provide two sets of lab work over the course of a year. Each set of lab work will include one blood draw, one urine sample, and height, weight, and blood pressure measurements. In order to track long-term health, information from participants' lab work will be linked with study-related health data, as well as surveys they have completed with the Wounded Warrior Recovery Project (WWRP).
The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on oesophageal symptoms and disease, including the presence of Barrett oesophagus ≥ 5 years post-surgery.
The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on bone mineral density, fracture risk, and body composition ≥ 5 years post-surgery.
A number of large trials have confirmed the benefits of thrombolysis in acute stroke, but there are gender differences. The authors sought to examine the relationship between sex and outcome after thrombolysis. Previous reports [1-6] concerning sex-related differences in stroke management and outcome are inconsistent and sometimes difficult to interpret, and so the reasons for gender disparities in stroke outcome have remained unclear. Functional outcomes and quality of life after stroke are consistently poorer in women despite adjustment for baseline differences in age and prestroke function, and the fact that comorbidities and clinical outcomes were not different between women and men [3, 7] . Once the reasons for these differences are better understood, intervention might be possible to help provide the best care for all patients. This work is a continuation and extension of the Ebrictus Study [8-10] . Prior work has suggested sex-based differences in thrombolytic therapy in subjects with acute stroke [11] .The authors will explore whether sex might modify the effect of thrombolysis on survival and functional outcomes in patients with acute ischemic stroke [12] beyond the usually evaluated time period of 6 months after stroke and compared this with the group without thrombolytic treatment.
