A time to look back: analysis of morphokinetic characteristics of human embryo development.

2013

Objective To describe the times associated with the morphological changes that occur in the embryo during preimplantation development based on the largest sample size described with time lapse. Design Cohort study. Setting University-affiliated private center. Patient(s) A total of 9,530 embryos from 1,806 intracytoplasmic sperm injection (ICSI) cycles. Intervention(s) None. Main Outcome Measure(s) Using a time-lapse system, embryo images were acquired for at least 68 hours, in some cases reaching 120–130 hours. Embryo cleavage time points up to 8-cell-stage (t2–t8) as well as morulae (tM) and blastocyst formation (tB) were registered in hours after ICSI. Additionally, duration of the cell …

Anatomical basis for the interposition of a gastric pouch between the ileum and the anus after total proctocolectomy.

2003

After a total proctocolectomy, ileoanal continuity is achieved by an ileal pouch–anal anastomosis. This anastomosis is not possible when the ileum cannot reach the anus. To avoid definitive ileostomy in this circumstance, we devised a gastric pouch, taken from the left half of the vertical portion of the stomach, vascularized by the right gastroepiploic pedicle, then interposed it between the ileum and the anus. The aim of this anatomical study on seven cadavers was to estimate the capacity of this gastric pouch to reach the anus. The distance between the caudal edge of the pubic symphysis and the apex of the pouch was measured. It is accepted that an ileal pouch always reaches the anus wit…

Correlation of preoperative imaging characteristics with donor outcomes and operative difficulty in laparoscopic donor nephrectomy

2019

This study aimed to understand the relationship of preoperative measurements and risk factors on operative time and outcomes of laparoscopic donor nephrectomy. Two hundred forty-two kidney donors between 2010 and 2017 were identified. Patients' demographic, anthropomorphic, and operative characteristics were abstracted from the electronic medical record. Glomerular filtration rates (GFR) were documented before surgery, within 24 hours, 6, 12, and 24 months after surgery. Standard radiological measures and kidney volumes, and subcutaneous and perinephric fat thicknesses were assessed by three radiologists. Data were analyzed using standard statistical measures. There was significant correlat…

Transcatheter embolization of the kidney with butyl-2-cyanoacrylate: Experimental and clinical results

1978

The technique and efficacy of therapeutic catheter embolization of the kidney with butyl-2-cyanoacrylate (Histoacryl) were studied in 80 rabbits (including control groups) and in 10 dogs. A mixture of butyl-2-cyanoacrylate, 50% glucose, and tantalum powder was used for the embolization. Complete and permanent vascular occlusion was found in nearly all cases. The main complication observed was a reflux of embolizing material into the lumbar arteries, which occurred in seven rabbits. Clinically, therapeutic embolization was performed in six patients with hypernephroma. The indication for embolization in these patients, as well as in two others with iatrogenic lesions, was pronounced hematuria…

An International, Multicenter Retrospective Observational Study to Assess Technical Success and Clinical Outcomes of Patients Treated with an Endovas…

2022

Introduction: Type III endoleaks post-endovascular aortic aneurysm repair (EVAR) warrant treatment because they increase pressure within the aneurysm sac leading to increased rupture risk. The treatment may be difficult with regular endovascular devices. Endovascular aneurysm sealing (EVAS) might provide a treatment option for type III endoleaks, especially if located near the flow divider. This study aims to analyze clinical outcomes of EVAS for type III endoleaks after EVAR. Methods: This is an international, retrospective, observational cohort study including data from 8 European institutions. Results: A total of 20 patients were identified of which 80% had a type IIIb endoleak and the r…

Effect of ischemic postconditioning on microvascular obstruction in reperfused myocardial infarction. Results of a randomized study in patients and o…

2014

Background: Ischemic postconditioning (PCON) appears as a potentially beneficial tool in ST-segment elevation myocardial infarction (STEMI). We evaluated the effect of PCON on microvascular obstruction (MVO) in STEMI patients and in an experimental swine model. Methods: A prospective randomized study in patients and an experimental study in swine were carried out in two university hospitals in Spain. 101 consecutive STEMI patients were randomized to undergo primary angio-plasty followed by PCON or primary angioplasty alone (non-PCON). Using late gadolinium enhancement cardiovascular magnetic resonance, infarct size and MVO were quantified (% of left ventricular mass). In swine, using an ang…

The Impact of the Introduction of Innovative REDS Scale for the Evaluation of Central Tunnelled Catheter (CTC) Exit Site on Infection Prevention in L…

2021

Central tunneled catheter (CTC)-related infections are a leading cause of a catheter loss, thus being the source of significant morbidity and mortality. The study aims at evaluating the impact of the implementation of the innovative redness, edema, discharge and tenderness, symptoms (REDS) scale (devised by the authors) for the description of the tunnel condition on the frequency of infection in long-term catheter users. The same cohort of the 40 patients was observed for 4 years altogether: 2 years before and 2 years after REDS application. The results, as well as follow-up evaluation of participants, were compared. The 2-year cumulative incidence of the CTC exit site infection (ESI) dropp…
