A promising approach is to augment the anti-tumour immune response in these patients; most cancers do not activate immune effector cells because they express immunosuppressive ligands. We have previously shown that CD200 (an immunosuppressive ligand) is overexpressed in AML and confers an inferior overall survival compared to CD200low/neg patients. Here we show that a fully human anti-CD200 antibody (TTI-CD200) can block the interaction of CD200 with its receptor and restore AML immune responses in vitro and in vivo.
Higher expression of olfactomedin-4 (OLFM4), a gene regulated by nuclear factor-kappa B (NF-κB), has been related to a higher risk of organ failure and death in patients with septic shock. We aimed to evaluate the association between OLFM4 single nucleotide polymorphisms (SNPs) and septic shock-related death in 175 patients who underwent major surgery, as well as its performance in predicting mortality.

We carried out a retrospective study. A total of seven OLFM4 SNPs were genotyped by Agena Bioscience's MassARRAY platform. Statistical analysis was performed by Kaplan-Meier and Cox regression tests. The diagnostic performance for predicting septic shock-related death was evaluated by the area under the receiver-operating characteristic (AUROC) curve.

Patients with rs17552047 A allele and rs1891944 TT genotype had higher survival than patients with rs17552047 G allele (P-value=.024) and patients with rs1891944 CC/CT genotype (P-value=.038). However, only rs17552047 was associated with a lower risk of death under an additive inheritance model (adjusted hazard ratio [aHR]=0.44, 95% CI=0.27-0.71). The multivariate model with the most significant clinical variables (lactate, chronic kidney disease, peritonitis, heart disease and elective surgery) showed an AUROC of 0.776 for predicting septic shock-related death. see more When we added the OLFM4 rs17552047 SNP to the previous model, the AUROC was 0.811 and was close to reaching significant differences with the previous model (P-value=.065).

OLFM4 rs17552047 A allele predicts septic shock survival in patients who underwent major surgery. Furthermore, rs17552047, together with clinical variables, could be useful to predict the outcome of septic shock.

Forecasting drug exposures using pharmacometric models can improve individual target attainment when compared with conventional therapeutic drug monitoring (TDM). However, selecting the "correct" model for this model-informed precision dosing (MIPD) is challenging. We derived and evaluated a model selection algorithm (MSA) and a model averaging algorithm (MAA), which automates model selection and finds the best model or combination of models for each patient using vancomycin as a case study, and implemented both algorithms in the MIPD software "TDMx." The predictive performance (based on accuracy and precision) of the two algorithms was assessed in (i) a simulation study of six distinct populations and (ii) a clinical dataset of 180 patients undergoing TDM during vancomycin treatment and compared with the performance obtained using a single model. Throughout the six virtual populations the MSA and MAA (imprecision 9.9-24.2%, inaccuracy less than ± 8.2%) displayed more accurate predictions than the single models (imprecision 8.9-51.1%; inaccuracy up to 28.9%). In the clinical dataset, the predictive performance of the single models applying at least one plasma concentration varied substantially (imprecision 28-62%, inaccuracy -16 to 25%), whereas the MSA or MAA utilizing these models simultaneously resulted in unbiased and precise predictions (imprecision 29% and 30%, inaccuracy -5% and 0%, respectively). MSA and MAA approaches implemented in TDMx might thereby lower the burden of fit-for-purpose validation of individual models and streamline MIPD.
Asherman syndrome (AS) is a symptomatic intrauterine adhesion caused by endometrial basal layer fibrosis as a result of either uterine cavity surgery or infection leading to many complications. There is a concern to repair the injured tissues by using bone marrow mesenchymal stem cells (BM-MSCs). We aimed in this study to develop an animal model of AS and evaluate the anti-inflammatory and anti-fibrotic effects of BM-MSCs in this model through histological, immunohistochemical, and morphometric studies.

Forty-two adult female adult albino rats were divided into (i) donor group composed of 2 rats used for isolation and propagation of BM-MSCs, and (ii) experimental groups 40 rats equally divided into 4 groups GpI (control), GpII (AS model), GpIII (BM-MSCs-treated AS rats), GpIV (untreated AS rats). Histological staining and immunohistochemical (IHC) detection of proliferating cell nuclear antigen (PCNA), vascular endothelial growth factor (VEGF), and nuclear factor-kappa beta (NF-kB) were performed. The results were evaluated by morphometric and statistical analysis.

Significant endometrial thinning, fibrosis, and degeneration of the endometrial epithelium with a significant decrease in PCNA and VEGF immunoexpression and a significant increase in NF-kB immunoexpression were detected in GpII and GpIV groups. These changes were substantially reversed in BM-MSCs-treated animals.

BM-MSCs treatment resulted in substantial improvement of intrauterine adhesion in the rat model of Asherman syndrome.

Spinal infarction is a rare condition and usually presents with a sudden or acute course. A prolonged course is rare and may mimic the presentation of inflammatory myelitis. Here we present a case of atypical spinal cord infarction with a stuttering course for six days..

A 47-year-old male presented initially with symptoms of sudden onset, limb pain. Sudden chest pain radiating to the back, occurred three days later. Sudden urinary retention and quadriparesis were presented after another three days. The diagnosis of spinal cord infarction was made through diffusion restriction in spinal magnetic resonance imaging.

A prolonged course of spinal cord infarction is relatively uncommon but a stepwise and stuttering course may provide clues. Diffusion restriction in magnetic resonance imaging also may be helpful. The diagnosis of spinal cord infarction should always be kept in mind.
