Purpose: To examine technical parameters of measurement accuracy and differences in tumor response classification using RECIST 1.1 and volumetric assessment in three common metastasis types (lung nodules, liver lesions, lymph node metastasis) simultaneously.

Materials And Methods: 56 consecutive patients (32 female) aged 41-82 years with a wide range of metastatic solid tumors were examined with MSCT for baseline and follow up.

Objective: To prospectively analyze duplex sonography, CTA, and MRA with respect to stenosis grading of the celiac trunk (TC) and the superior mesenteric artery (SMA), with DSA as the reference.

Materials And Methods: 52 subjects were enrolled (mean age: 71). The image quality was graded: 1-insufficient, 2-bad, 3-moderate, 4-good or 5-excellent.

Article Synopsis
  • Researchers developed and tested four prototypes of sheath-turning auxiliary devices (STADs) designed for easier catheter direction changes during endovascular procedures, using modified dilators and catheters.
  • In an evaluated in vitro setup with bovine veins, success rates ranged from 75% to 90% for the prototypes, with average procedure times around 60 seconds; handling and reliability varied among the prototypes.
  • A patient observation study indicated that the maximum soft tissue thickness (STTmax) in the common femoral artery averaged 3.3 cm, with most patients having STTmax ≤ 5 cm, suggesting the devices need optimization for thicker tissues.

Here, we report the identification of a new human leukocyte antigen (HLA)-B*44 allele found almost simultaneous in three DNA samples which were part of routine bone marrow donor typing by order of the German registry 'Aktion Knochenmarkspende Bayern'. The samples appeared noticeable in different polymerase chain reactions using sequence-specific primers (PCR-SSP) or sequence-specific oligonucleotides (PCR-SSO). Sequence-based typing revealed a novel allele officially designated as B*4441*.

A new human leukocyte antigen (HLA)-B allele was found during routine typing of samples for a German unrelated bone marrow donor registry, the "Aktion Knochenmarkspende Bayern". After first interpretation of data of two independent low-resolution sequence-specific oligonucleotide typing tests, a B*51 variant was suggested. Further analysis via sequence-based typing identified the sequence as new B*52 allele.

IL-10 is a potent immunosuppressant which inhibits allo-antigen-specific T cell responses. In addition, IL-10 is a strong endogenous anti-inflammatory cytokine. To investigate the role of IL-10 in the induction of acute GVHD following allogeneic bone marrow transplantation (BMT) we performed a prospective study on spontaneous IL-10 production by peripheral blood mononuclear cells (PBMNC) in 84 patients admitted for allogeneic BMT.

Transfusion-associated graft-versus-host disease (TA-GVHD) resulting from the engraftment of competent lymphocytes contained in blood products has been well described in immunocompromised patients and more recently in immunocompetent patients. Prophylactic irradiation of blood products prior to transfusion is the most efficient way to prevent TA-GVHD. Standard blood bank measures to reduce mononuclear cell contamination in red blood cell units, such as freezing, washing and filtration, may reduce the number of viable lymphocytes to prevent immunizations.

Monoclonal antibodies are increasingly used for treatment of acute graft-versus-host disease (aGVHD) in bone marrow transplantation. We treated seven patients with steroid resistant aGVHD with the monoclonal anti-T cell antibody OKT3. Though five patients showed improvement of aGVHD, only two became long-term survivors.
