003), and a trend towards an overexpression of STAR mRNA (p = 0.06). Concerning oocytes genes, both techniques did not lead to a difference of GDF9 and ZP3 mRNA. Concerning cell cycle genes, slow freezing led to a significant underexpression of CCND2 (p = 0.04); while vitrification did not lead to a difference for CCND2 and CDKN1A mRNA. CONCLUSION Vitrification preserved follicular morphology better than slow freezing and led to gene overexpressed, while slow freezing led to gene underexpressed.BACKGROUND In less well-resourced countries, the high cost of commercially available peritoneal dialysis (PD) fluid limits its use. The major concerns regarding bedside-prepared PD fluid is peritonitis as well as electrolyte disorders. The aim of this study was to review our experience with the use of PD fluids prepared at the bedside using the intravenous infusion solution Balsol (Fresenius Kabi). METHODS This was a retrospective review of all patients who received PD for acute kidney injury (AKI) using a bedside-prepared PD solution adapted from the intravenous solution Balsol in our intensive care unit. RESULTS In total, 49 cases of acute PD were performed. Of the 49 children, 21 (43%) were male. The ages of the patients ranged from newborn to 10.2 years (median 0.33 years). The weight of children ranged from 1.3 kg to 50 kg (median 4.1 kg). The type of PD catheters used Cook catheters, 41 patients; Kimal peel-away, 10 patients; and surgical inserted Tenckhoff type of catheter, 2 patients. The duration of PD was 1-17 days (median 3 days) Complications included peritonitis in 2 of 49 patients and blocked catheter in 6 of 49 patients. There were no electrolyte disturbances as a result of the PD. Overall survival was 43% of patients. CONCLUSIONS Locally prepared PD solutions at the bedside adapted from intravenous solutions can be used safely and effectively. This has important relevance for centres in less well-resourced countries, where commercially produced PD fluid is not available for the management of AKI.BACKGROUND Immune checkpoint inhibitors (ICIs) frequently cause thyroid dysfunction but its underlying mechanism remains unclear. We have previously demonstrated increased circulating natural killer (NK) cells and HLA-DR surface expression on inflammatory intermediate CD14+CD16+ monocytes in programmed cell death protein-1 (PD-1) inhibitor treated patients. This study characterizes intrathyroidal and circulating immune cells and class II HLA in ICI-induced thyroiditis. METHODS This is a single center prospective cohort study of 10 patients with ICI-induced thyroiditis by flow cytometry of thyroid fine needle aspirates (n=9) and peripheral blood (n=7) compared to healthy thyroid samples (n=5) and healthy volunteer blood samples (n=44); HLA class II was tested in n=9. RESULTS ICI-induced thyroiditis samples demonstrated overall increased T lymphocytes (61.3% vs. 20.1%, p=0.00006), CD4-CD8- T lymphocytes (1.9% vs. 0.7%, p=0.006); and as percent of T lymphocytes, increased CD8+T lymphocytes (38.6% vs. 25.7%; p=0.0259) as compared to healthy thyroid samples. PD-1 inhibitor-induced thyroiditis had increased CD4+PD1+ T lymphocytes (40.4% vs. 0.8%; p=0.021) and CD8+PD1+ T lymphocytes (28.8% vs. 1.5%; p=0.038) in thyroid compared to blood. Circulating NK cells, certain T lymphocytes (CD4+CD8+, CD4-CD8- T, gamma delta) and intermediate monocytes were increased in ICI-induced thyroiditis. Six patients typed as HLA-DR4-DR53 and three as HLA-DR15. TMP269 order CONCLUSIONS ICI-induced thyroiditis is a T lymphocyte mediated process with intra-thyroidal predominance of CD8+ and CD4-CD8- T lymphocytes. HLA haplotypes may be involved but need further evaluation. These findings expand the limited understanding of ICI-induced thyroiditis, which could be further translated to guide immunomodulatory therapies for advanced thyroid cancer.Middle ear administration has numerous applications, including antibiotherapy and gene therapy, and is increasingly used to target the auditory and vestibular systems. In animal studies, investigating repeated exposure that mimics clinical dosing regimens has remained a challenge due to the lack of suitable models. Intratympanic injections are not suitable for long-term studies due to the increased risk related to tympanic membrane rupture or scarring and repeat anesthesia events. Surgical models of middle ear catheterization previously used have not been reliable for longer than 4 weeks, resulted in elevated stress levels, and have been associated with significant changes related to the surgery and/or the presence of the catheter such as local trauma and inflammatory and degenerative processes. These complications cause decreased hearing/deafness and greatly diminish the value and accuracy of ototoxicity studies. We describe here a procedure that permits repeat dosing into the middle ear of guinea pigs and can be used to produce a model of aminoglycoside-induced hair cell injury. The innocuity of the procedures and the efficacy of the ototoxicity model were confirmed using auditory brain stem response assessment, histopathological evaluation, and cytocochleograms. Procedure-related changes were limited to minimal inflammation in the middle ear.Several hundred U.S. conflict resolution and restorative justice programs are addressing community violence using neutral facilitation to help people in conflict, or those who have experienced a crime, to talk things out face-to-face and come up with self-determined solutions. Very little quantitative intervention research has been conducted on the capacity of these programs to reduce violence, violent crime, and criminal recidivism. The scientific literature pertaining to the association of conflict resolution interventions with violence prevention are identified, screened, and sorted. Study design, sampling, measurement, and analyses are assessed using objective standards. Individual criminal recidivism outcomes and neighborhood gun violence rates are charted. In the 10 included studies, disparate conflict resolution and restorative justice interventions each appears to be related to modest reductions in individual criminal recidivism for participants, when compared with standard criminal justice system treatment.
