Round-Robin test for the histological diagnosis of acute colonic Graft-versus-Host disease validating established histological criteria and grading systems.

Histomorpholgy is one of the mainstays of acute Graft-versus-host disease (GvHD) diagnosis. However, concerns about reproducibility and the most appropriate grading system question its usefulness. Our aim was to assess histomorphological parameters and previously reported grading systems for GvHD regarding reproducibility and validity.

Being in the Know: The Role of Awareness and Retrieval of Transient Stimulus-Response Bindings in Selective Contingency Learning.

Previous studies demonstrated that contingency learning can be both (a) unaware (Schmidt et al., 2007), and (b) explained in terms of an automatic retrieval of stimulus-response bindings from the last episode in which the cue stimulus has been presented (Giesen et al., 2020; Schmidt et al.

The role of single-nucleotide polymorphisms of the 8q24 chromosome region in patients with concomitant bladder and prostate cancer.

Objective: To assess whether single-nucleotide polymorphisms (SNPs) of the 8q24 chromosome region are associated with recurrence-free survival (RFS) after radical cystoprostatectomy (RC) in patients with concomitant bladder (BC) and prostate cancer (PC).

Materials And Methods: A cohort of thirty-six patients treated with RC and pelvic lymph node dissection and histologically exhibited invasive BC and incidental PC. Using Sanger sequencing, a total of seven SNPs in the androgen-responsive element of the promoter region of the following genes were assessed in tumor-free lymph nodes and correlated with oncological outcomes: PSCA (rs2294008, rs2978974, rs1045531, rs3736001), MYC (rs6983267), FXBO32 (rs7830622), and MIR151A (rs14974929).

A novel concept of screening for subgrouping factors for the association between socioeconomic status and respiratory allergies.

Background: The new subgroup screening tool "subscreen" aims to understand the unclear and complex association between socioeconomic status (SES) and childhood allergy. This software R package has been successfully used in clinical trials but not in large population-based studies.

Objective: To screen and identify subgrouping factors explaining their impact on the association between SES and respiratory allergies in childhood and youth.

Management of Muscle-invasive Bladder Cancer in the 2020s: Challenges and Perspectives.

Despite an increased use of neoadjuvant and adjuvant chemotherapy, the long-term survival rates after radical cystectomy or trimodal therapy (TMT) for muscle-invasive bladder cancer (MIBC) remain basically unchanged for decades. Detection and effective treatment of micrometastatic disease are still a clinical dilemma. Assessment of circulating tumor DNA in combination with improved imaging modalities may improve the prediction of micrometastatic disease.

Radical Cystectomy in Female Patients - Improving Outcomes.

Purpose Of Review: To review the methods of improving surgical, oncological, and functional outcomes in women with bladder cancer treated with radical cystectomy.

Recent Findings: Οrthotopic urinary diversion (ONB) is a safe option for well-selected women as it combines high rates of daytime and nighttime continence with exceptional oncologic outcomes. It is considered safe even for patients with limited lymph node disease and trigone involvement, as long as a preoperative biopsy of the bladder neck or an intraoperative frozen section analysis of distal urethral margin rules out malignant disease.

EAU-ESMO Consensus Statements on the Management of Advanced and Variant Bladder Cancer-An International Collaborative Multistakeholder Effort: Under the Auspices of the EAU-ESMO Guidelines Committees.

The prognostic impact of hexaminolevulinate-based bladder tumor resection in patients with primary non-muscle invasive bladder cancer treated with radical cystectomy.

Purpose: To investigate whether hexaminolevulinate-based (HAL) bladder tumor resection (TURBT) impacts on outcomes of patients with primary non-muscle-invasive bladder cancer (NMIBC) who were eventually treated with radical cystectomy (RC).

Methods: A total of 131 consecutive patients exhibiting NMIBC at primary diagnosis were retrospectively investigated whether they had undergone any HAL-guided TURBT prior to RC. Uni- and multivariable analyses were used to evaluate the impact of HAL-TURBT on cancer-specific (CSS) and overall survival (OS).

Follistatin Effects in Migration, Vascularization, and Osteogenesis and Bone Repair .

The use of biomaterials and signaling molecules to induce bone formation is a promising approach in the field of bone tissue engineering. Follistatin (FST) is a glycoprotein able to bind irreversibly to activin A, a protein that has been reported to inhibit bone formation. We investigated the effect of FST in critical processes for bone repair, such as cell recruitment, osteogenesis and vascularization, and ultimately its use for bone tissue engineering.

The prognostic effect of salvage surgery and radiotherapy in patients with recurrent primary urethral carcinoma.

Background: To evaluate the impact of salvage therapy (ST) on overall survival (OS) in recurrent primary urethral cancer (PUC).

Patients: A series of 139 patients (96 men, 43 women; median age = 66, interquartile range: 57-77) were diagnosed with PUC at 10 referral centers between 1993 and 2012. The modality of ST of recurrence (salvage surgery vs.

Gene expression and epigenetic aberrations in F1-placentas fathered by obese males.

Gene expression and/or epigenetic deregulation may have consequences for sperm and blastocysts, as well as for the placenta, together potentially contributing to problems observed in offspring. We previously demonstrated specific perturbations of fertilization, blastocyst formation, implantation, as well as aberrant glucose metabolism and adiposity in offspring using a mouse model of paternal obesity. The current investigation analyzed gene expression and methylation of specific CpG residues in F1 placentas of pregnancies fathered by obese and normal-weight male mice, using real-time PCR and bisulfite pyrosequencing.

In vitro-generated MDSCs prevent murine GVHD by inducing type 2 T cells without disabling antitumor cytotoxicity.

Myeloid-derived suppressor cells (MDSCs) inhibit T-cell expansion and functions by versatile mechanisms such as nutrient depletion, nitrosylation, or apoptosis. Since graft-versus-host disease (GVHD) is characterized by the expansion of donor-derived T cells destroying recipient tissue, we analyzed whether MDSCs can be used for GVHD prevention in murine allogeneic bone marrow transplantation models. Transplantation of MDSCs, generated from bone marrow cells by granulocyte-macrophage colony-stimulating factor (GM-CSF)/G-CSF in vitro, inhibited GVHD-induced death and attenuated histologic GVHD, whereas antitumor cytotoxicity of alloantigen-specific T cells was maintained.

The phosphoproteome and its physiological dynamics in Staphylococcus aureus.

Phosphorylation events on proteins during growth and stress/starvation can represent crucial regulation processes inside the bacterial cell. Therefore, serine, threonine and tyrosine phosphorylation patterns were analyzed by two powerful complementary proteomic methods for the human pathogen Staphylococcus aureus. Using 2D-gel analysis with a phosphosensitive stain (Pro-Q Diamond) and gel-free titanium dioxide based phosphopeptide enrichment, 103 putative phosphorylated proteins with successfully mapped 68 different phosphorylation sites were found in the soluble proteome of S.

Expression of transketolase-like 1 and activation of Akt in grade IV glioblastomas compared with grades II and III astrocytic gliomas.

Transketolases link the Embden-Meyerhof pathway to the pentose phosphate pathway. An influence of p-Akt on this metabolism was described. This study was performed to compare the expression of transketolase-like 1 (TKTL1) and p-Akt in glioblastoma multiforme (GBM) and other astrocytic gliomas (AGs, grades II and III).

Short- and long-term results of laparoscopic gastric banding for morbid obesity.

Background: Today, gastric banding has become a common bariatric procedure. Weight loss can be excellent, but is not sufficient in a significant proportion of patients. Few long-term studies have been published.

Band erosion and passage, causing small bowel obstruction.

A rare complication of adjustable gastric banding is reported. A 65-year-old man developed recurrent vomiting, epigastric pain, and small-bowel obstruction 13 months after laparoscopic adjustable gastric banding for morbid obesity. Investigation revealed that the band had migrated completely into the gastric lumen and had passed far down the jejunum.

Transfusion-related acute lung injury (TRALI)--an important, severe transfusion-related complication.

Background: Transfusion-related acute lung injury (TRALI) is an immune-mediated transfusion reaction that can cause severe complications or even death. It is now the leading cause of transfusion-related death in the United States.

Methods: The TRALI syndrome is presented in two cases in a surgical intensive care unit and discussed against the background of the present literature.

Chemoimmunotherapy for melanoma with dacarbazine and 2,4-dinitrochlorobenzene: results from a murine tumour model.

An empirically established chemoimmunotherapy that combines the epifocal application of the contact sensitizer dinitrochlorobenzene (DNCB) to cutaneous metastases with the systemic administration of dacarbazine (DTIC) yields high response rates and results in prolonged survival. However, despite the fact that this therapy has been in clinical use for several years, the mode of action still remains elusive. In order to overcome this limitation we established a murine model system.
