Aim To prepare loratadine-loaded solid lipid nanoparticles (SLNs) using a modified two-step ultrasound-assisted phase inversion temperature (PIT) process. Results/methodology Loratadine was dissolved in beeswax and Tween 80 was dissolved in water. The two phases were mixed together to prepare a water-in-oil emulsion preconcentrate (w/o) at a PIT of 85°C, followed by gradual water addition at 25°C to trigger nanoparticles formation (o/w). Kinetic stability was investigated. No change in the size was observed within 6 months. Fourier-transform infrared spectroscopy demonstrated stability of the emulsions via molecular structure of water at the interface of the o/w nanoemulsions. SLNs enhanced the in vitro skin permeation of loratadine. Conclusion Stable SLNs were successfully prepared by ultrasound-assisted PIT.

Dual-lumen cannulas were designed to provide venovenous extracorporeal membrane oxygenation (VV ECMO) with single-vessel access. Anatomic and size considerations may make appropriate placement challenging in children. Dual-lumen cannulas are repositioned in 20-69% of pediatric patients, which can be difficult without transient discontinuation of ECMO support.

We repositioned three dual-lumen ECMO cannulas introduced via the right internal jugular vein using a transfemoral snare technique under real-time ultrasound and fluoroscopy.

Two of three patients were supported on VV ECMO and one on veno-veno-arterial (VV-A) ECMO. Two of the three patients had their dual-lumen cannula repositioned under ultrasound and fluoroscopy guidance and one was repositioned just with ultrasound. No patient experienced a complication from the transfemoral snare technique such as femoral hematoma, hemorrhage or limb ischemia.

We describe three patients who successfully had dual-lumen cannulas repositioned without cessation of ECMO using a transfemoral "lasso" technique.

One element of this is the requirement of postoperative blood transfusion. Patients who undergo elective lumbar decompression are at a low risk of requiring a postoperative transfusion yet undergo multiple preoperative group & save tests. For those who are at a low risk of bleeding, a single group & save sample may be adequate. This review analysed the postoperative blood loss and transfusion rate associated with lumbar decompression surgery without fusion in one institution. A subsequent cost analysis and review of the literature was performed. The aim was to assess whether single group & save sampling, within the context of lumbar decompression, was cost effective and amenable to the patient without impacting patient care. Average blood loss was estimated as a drop in Hb of 12.3g/dl. Six patients (14%) had Hb loss of over 20g/dl. No patients underwent a blood transfusion. Through examination of medical records, we found that 65% of patients (35) were suitable for single group & save sampling, estimating a saving of £2415.95 (53%). Selective group & save testing holds economic potential and safeguards patients from undergoing unnecessary testing. The next step after this review would be a prospective multi-centre study.This paper investigates intonation in the urban dialect of Liverpool, Scouse. Scouse is reported to be part of a group of dialects in the north of the UK where rising contours in declaratives are a traditional aspect of the dialect. This intonation is typologically unusual and has not been the subject of detailed previous research. Here, we present such an analysis in comparison with Manchester, a city less than 40 miles from Liverpool but with a noticeably different prosody. Our analysis confirms reports that rising contours are the most common realization for declaratives in Liverpool, specifically a low rise where final high pitch is not reached until the end of the phrase. Secondly, we consider the origin of declarative rises in Scouse with reference to the literature on new dialect formation. Our demographic analysis and review of previous work on relevant dialects suggests that declarative rises were not the majority variant when Scouse was formed but may have been adopted for facilitating communication in a diverse new community. We highlight this contribution of intonational data to research on phonological aspects of new dialect formation, which have largely considered segmental phonology or timing previously.Background. Completely minimally invasive esophagectomy (CMIE) has been associated with reduced morbidity compared to open esophagectomy in the treatment of esophageal cancer. Three-dimensional (3D) vision can enhance depth perception during minimally invasive surgery when compared to two-dimensional (2D) vision. We aimed to compare outcomes from 2-stage CMIEs when performed in 2D vs 3D. Method. All consecutive 2-stage CMIEs performed for esophageal or gastroesophageal junctional cancer at a single-centre between 2016 and 2018 were identified from a prospectively maintained database. All operations were completed in either 2D or 3D. All esophagogastric anastomoses were hand-sewn thoracoscopically. Intraoperative and postoperative clinical parameters were compared between 2D and 3D CMIE. Results. Overall, 98 patients underwent a 2-stage CMIE, of which 59 (60.2%) were in 2D and 39 (39.8%) in 3D. Olaparib ic50 Median operative blood loss was less in the 3D group compared to the 2D group (283 mls vs 409 mls, P = .016). A higher number of lymph nodes were retrieved from 3D CMIE (30 vs 25, P = .010). The median duration of surgery was 407 minutes (interquartile ranges (IQR) 358-472 minutes) and 426 minutes (IQR 369-509 minutes) when performed in 2D and 3D, respectively (P = .162). There were no significant intergroup differences in 30-day postoperative complications, short-term mortality, and hospital stay. Conclusion. We report reduced blood loss and higher lymph node yield when performing 3D CMIE than 2D CMIE. Other intraoperative and postoperative clinical outcomes were similar in both groups. A randomized controlled trial is needed to validate these findings of superior outcomes from CMIE performed in 3D over 2D.
