  Intubation and extubation generate large amounts of small particles that remain suspended in air for long durations and disperse through theatre. Endonasal access and pituitary tumour resection generate smaller concentrations of larger particles which are airborne for shorter periods and travel shorter distances.

To evaluate neural cell therapy to prevent cyst expansion and potentially replace lost neurons, we developed a rat model of PTS. We combined contusive trauma with subarachnoid injections of blood, causing tethering of the spinal cord to the surrounding vertebrae, resulting in chronically expanding cysts. The cysts were usually located rostral to the injury, extracanalicular, lined by astrocytes. T2*-weighted magnetic resonance imaging (MRI) showed hyperintense fluid-filled cysts but also hypointense signals from debris and iron-laden macrophages/microglia. Two types of human neural stem/progenitor cells-fetal neural precursor cells (hNPCs) and neuroepithelial-like stem cells (hNESCs) derived from induced pluripotent stem cells-were transplanted to PTS cysts. Cells transplanted into cysts 10 weeks after injury survived at least 10 weeks, migrated into the surrounding parenchyma, but did not differentiate during this period. The cysts were partially obliterated by the cells, and cyst walls often merged with thin layers of cells in between. Cyst volume measurements with MRI showed that the volumes continued to expand in sham-transplanted rats by 102%, while the cyst expansion was effectively prevented by hNPCs and hNESCs transplantation, reducing the cyst volumes by 18.8% and 46.8%, respectively. The volume reductions far exceeded the volume of the added human cells. Thus, in an animal model closely mimicking the clinical situation, we provide proof-of-principle that transplantation of human neural stem/progenitor cells can be used as treatment for PTS.Gadolinium (Gd)-contrast MRI for reliable detection of blood-brain barrier (BBB) breakdown is widely used in neuromyelitis optica spectrum disorder (NMOSD) attack. Nonetheless, little is known about the predictive role of gadolinium-enhancing lesion in prognosis of NMOSD attack. The aim of this work is to investigate the predictive value of persistently Gd-enhanced lesions to medium-term outcome after attack. Data for this analysis came from an ongoing prospective cohort study (CLUE). NMOSD patients with acute attack were enrolled from January 2019 to March 2020.  https://www.selleckchem.com/peptide/pki-14-22-amide-myristoylated.html  All patients underwent Gd-contrast MRI at baseline and 1 month, and disability was assessed by Expanded Disability Status Scale (EDSS). Primary outcome was EDSS improvement from baseline to month 6. Multiple logistic regression identified predictors for poor recovery of NMOSD attack. Forty-one participants were analyzed, of which 21 patients had persistently Gd-enhancing lesions. Patients in no enhancement (NE) group showed a significant shift in 6-month EDSS distributions compared with those in persistent enhancement (PE) group (p = 0.005). Poor recovery rate of the PE group was higher than that of the NE group at 6 months (p = 0.033). In patients with aquaporin-4-positive, first-attack, transverse myelitis or in a high-dose steroid treatment subgroup, the improvement of EDSS scores in the PE group was still less compared with that in the NE group (p  less then  0.05). The presence of persistently Gd-enhancing lesion appears to be associated with poor recovery after attack (OR = 5.473, p = 0.014). Our study found that persistently gadolinium-enhancing lesion is a poor prognosis predictor after NMOSD attack. Trial registration ID NCT04106830.Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive, life-threatening disease characterized by the aggregation and deposition of amyloidogenic misfolded transthyretin (TTR) in the myocardium. The gradual accumulation of insoluble TTR amyloid fibrils can result in restrictive cardiomyopathy and heart failure. Tafamidis (Vyndaqel®; Vyndamax®), a TTR stabilizer, has been approved for use in the treatment of adults with ATTR-CM in several countries. Tafamidis stabilizes both wild-type and mutant TTR, inhibiting the formation of TTR amyloid fibrils. In the pivotal phase III ATTR-ACT trial, tafamidis significantly reduced all-cause mortality and frequency of cardiovascular-related hospitalizations relative to placebo in patients with ATTR-CM. In addition, tafamidis recipients experienced significantly less deterioration in 6-minute walk test distance and quality of life than placebo recipients over the 30-month treatment period. Treatment benefits were largely consistent between patients with wild-type TTR and patients with a variant TTR genotype. Tafamidis was generally well tolerated in patients with ATTR-CM and, with a safety profile similar to that of placebo, tafamidis is suitable for long-term use. Given that treatment for this condition has in the past been largely limited to symptom management, tafamidis constitutes a valuable disease-modifying therapy for patients with ATTR-CM.
  Due to an increase in survival, a growing population of childhood cancer survivors (CCS) is present. However, female CCS are at risk of developing premature ovarian insufficiency (POI) after cancer treatment. POI involves a decreased chance of conceiving and the increased infertility state has a large impact on affected individuals' health and mental life. The objective of this study was to investigate health state and well-being among female CCS with and without POI and healthy controls (HC).
 
  Female CCS treated in southern Sweden between 1964 and 2008 were included. Each patient was matched with a HC. The final study population included 167 female CCS and 164 HC that were examined between October 2010 and January 2015 at the Reproductive Medicine Centre at Skåne University Hospital in Malmö, Sweden. All participants, except for two HCs, answered an EQ-5D-3L questionnaire for measuring health state including a visual analogue scale (VAS) for estimating well-being.
 
  There were 22 CCS with POI, none of the HC had POI.
