Background: Primary effusion lymphoma (PEL) is a lymphoid proliferation related to Kaposi sarcoma herpesvirus 8/human herpesvirus 8 (KSHV/HHV8) that affects mainly human immunodeficiency virus (HIV) infected individuals but can also occur in other immunodeficiency settings. It is characterized by lymphomatous effusions in different serous body cavities without the presence of a detectable tumor mass. The diagnosis is challenging and the clinical outcomes are poor. Aim: The aim of this paper is to report a rare case of PEL in a man who have sex with women (MSW) with HIV-1/2 infection, history of visceral Kaposi sarcoma (KS) and the development of a seronegative arthritis previous to the lymphoproliferative disease diagnosis. PEL presented with ascites, was treated with high-dose chemotherapy and autologous stem cell transplantation, with a good clinical outcome. Case Presentation: We describe a case of a 48-year-old HIV-1/2-infected patient from a high HHV8 seroprevalent country, hospitalized following a three-month history of increased abdominal volume and general constitutional symptoms. Laboratory data revealed normocytic normochromic anemia and a high level of lactate dehydrogenase. A diagnostic paracentesis was performed with cytology compatible with high-grade B-cell lymphoma. Peritoneal fluid cytology showed large lymphoid cells expressing leucocyte-common antigen CD45 without expression of the CD20 antigen (B-lymphocytes) and positivity for HHV8 by immunocytochemical staining, compatible with the diagnosis of PEL.

Combinatorial therapies for spinal cord injury repair

引用

Neural Regeneration Research 2025年第5期20卷 1293-1308页

Spinal cord injuries have profound detrimental effects on individuals, regardless of whether they are caused by trauma or non-traumatic events. The compromised regeneration of the spinal cord is primarily attributed to damaged neurons, inhibitory molecules, dysfunctional immune response, and glial scarring. Unfortunately, currently, there are no effective treatments available that can fully repair the spinal cord and improve functional outcomes. Nevertheless, numerous pre-clinical approaches have been studied for spinal cord injury recovery, including using biomaterials, cells, drugs, or technological-based strategies. Combinatorial treatments, which target various aspects of spinal cord injury pathophysiology, have been extensively tested in the last decade. These approaches aim to synergistically enhance repair processes by addressing various obstacles faced during spinal cord regeneration. Thus, this review intends to provide scientists and clinicians with an overview of pre-clinical combinatorial approaches that have been developed toward the solution of spinal cord regeneration as well as update the current knowledge about spinal cord injury pathophysiology with an emphasis on the current clinical management.

Percutaneous nephrostomy versus ureteral stent in hydronephrosis secondary to obstructive urolithiasis:A systematic review and meta-analysis

Objective: To assess if there is a preferable intervention between retrograde ureteral stent (RUS) and percutaneous nephrostomy (PCN) tube, in cases of upper urinary tract stone obstruction with complications requiring urgent drainage, by evaluating outcomes regarding urinary symptoms, quality of life (QoL), spontaneous stone passage, and length of hospital stays, since there is no literature stating the superiority of one modality over the ***: We searched MEDLINE and other sources for relevant articles in June 2019 without any date restrictions or filters applied. The selection was done first by the title and abstract screening and then by full-text assessment for eligibility. Only randomized controlled trials or cohort studies in patients with hydronephrosis secondary to obstructive urolithiasis that presented comparative data between PCN and RUS placement concerning at least one of the defined outcome measures were included. Lastly, MEDLINE database and PubMed platform were screened again using the same terms, from June 2019 until November ***: Of 556 initial articles, seven were included in this review. Most works were considered of moderate-to-high quality. Three studies regarding QoL showed a tendency against stenting, even though only one demonstrated statistically significant negative impact on overall health state. Two works reported significantly more post-intervention urinary symptoms in stenting patients. One article found that PCN is a significant predictor of spontaneous stone passage, when adjusted for stone size and location. Findings on length of hospital stays were not consistent among ***: PCN appears to be the intervention better tolerated, with less impact on the patient’s perceived QoL and less post-operative urinary symptoms, in comparison with RUS. Nevertheless, further studies with larger samples and a randomized controlled design are suggested.

Graphite Nucleation in Cast Iron Melts Based on Solidification Experiments and Microstructure Simulation

引用

Journal of Materials Science & Technology 2008年第3期24卷 321-324页

作者： andreia Sommerfeld Bernd Bttger Babette Tonn Institute of Metallurgy Clausthal University of TechnologyClausthal-Zellerfeld ACCESS e.V. Intzestr.552072 Aachen

Microstructure strongly influences the mechanical properties of cast iron. By inoculating the melt with proper inoculants, foreign substrates are brought into the melt and eventually the graphite can crystallize on them. The elements and substrates that really play a role for nucleation are yet unknown. Until now there is very little knowledge about the fundamentals of nucleation, such as composition and morphology of nuclei. In this work we utilized EN-GJL-200 as a base material and examined several produced specimens. The specimens were cast with and without inoculants and quenched at different solidification states. Specimens were also examined with a high and low oxygen concentration, but the results showed that different oxygen contents have no influence on the nucleation in cast iron melts. Our research was focused on the microscopic examination and phase-field simulations. For studying the samples we applied different analytical methods, where SEM-EDS, -WDS were proved to be most effective. The simulations were conducted by using the software MICRESS, which is based on a multiphase-field model and has been coupled directly to the TCFE3 thermodynamic database from TCAB. On the basis of the experimental investigations a nucleation mechanism is proposed, which claims MnS precipitates as the preferred site for graphite nucleation. This theory is supported by the results of the phase-field simulations.
