Long-term oncological outcomes of bladder cancer: a population-based study with a 25-year follow-up.

Objective: To describe the oncological outcomes for patients with newly diagnosed bladder cancer, as long-term oncological outcomes and natural history of different initial subtypes of diagnoses of bladder cancer are understudied.

Patients And Methods: This was a prospective, multicentre population-based cohort study, where newly diagnosed patients with bladder cancer from 1995 to 1996 in Stockholm County, Sweden were followed. The primary outcome was cancer-specific mortality (CSM), separately analysed for low-grade non-muscle-invasive bladder cancer (NMIBC Low), high-grade non-muscle-invasive bladder cancer (NMIBC High), and muscle-invasive bladder cancer (MIBC).

An open-source platform for structured annotation and computational workflows in digital pathology research.

The rapid evolution of digital pathology has enabled large-scale data acquisition, driving sophisticated clinical research and advancing the development of AI-driven tools. These innovations have also revolutionised histopathological slide review, especially the annotation step (i.e.

Pelvic lymph-node dissections in bladder and prostate cancer surgery and the risk of postoperative venous thromboembolism.

Introduction: To evaluate the risk of venous thromboembolic events in patients operated with radical cystectomy or radical prostatectomy and pelvic lymph-node dissection.

Material And Methods: Patients operated with radical cystectomy for bladder cancer or with radical prostatectomy for prostate cancer from 1997 through 2016 were identified from Swedish nationwide registers. We estimated odds ratios of association between lymph-node dissection and pulmonary embolism and deep venous thrombosis (DVT) using logistic regression adjusted for the probability of having lymph-node dissection.

Risk of Venous Thromboembolic Events After Surgery for Cancer.

Importance: The risks and benefits of thromboprophylaxis therapy after cancer surgery are debated. Studies that determine thrombosis risk after cancer surgery with high accuracy are needed.

Objectives: To evaluate 1-year risk of venous thromboembolic events after major cancer surgery and how these events vary over time.

Risk of Postoperative Ischemic Stroke and Myocardial Infarction in Patients Operated for Cancer.

Background: Risk assessment for ischemic stroke (IS) and myocardial infarction (MI) is done routinely before surgery, but the increase in risks associated with surgery is not known. The aim of this study is to assess the risk of arterial ischemic events during the first year after oncological surgery.

Methods: We used Swedish healthcare databases to identify 443,300 patients who underwent cancer surgery between 1987 and 2016 and 4,127,761 matched comparison subjects.

Effect of digital-enabled multidisciplinary therapy conferences on efficiency and quality of the decision making in prostate cancer care.

Objectives: To investigate the impact on efficiency and quality of preprostatectomy multidisciplinary therapy conferences (MDT) at Karolinska University Hospital related to the use of a digital solution compared with standard of care. Further, to explore whether gains in MDT efficiency and quality impact oncological or functional patient outcomes.

Methods: We conducted a prospective, observational study of preoperative prostate cancer MDT at Karolinska between February 2017 and March 2021, including 1329 patients.

Characteristics of Patients in SPCG-15-A Randomized Trial Comparing Radical Prostatectomy with Primary Radiotherapy plus Androgen Deprivation Therapy in Men with Locally Advanced Prostate Cancer.

Background: There is no high-grade evidence for surgery as primary treatment for locally advanced prostate cancer. The SPCG-15 study is the first randomized trial comparing surgical treatment with radiotherapy.

Objective: To describe the baseline characteristics of the first 600 randomized men in the SPCG-15 study.

Prognostic Utility of the Gleason Grading System Revisions and Histopathological Factors Beyond Gleason Grade.

Background: The International Society of Urological Pathology (ISUP) revised the Gleason system in 2005 and 2014. The impact of these changes on prostate cancer (PCa) prognostication remains unclear.

Objective: To evaluate if the ISUP 2014 Gleason score (GS) predicts PCa death better than the pre-2005 GS, and if additional histopathological information can further improve PCa death prediction.

Interchangeability of light and virtual microscopy for histopathological evaluation of prostate cancer.

Virtual microscopy (VM) holds promise to reduce subjectivity as well as intra- and inter-observer variability for the histopathological evaluation of prostate cancer. We evaluated (i) the repeatability (intra-observer agreement) and reproducibility (inter-observer agreement) of the 2014 Gleason grading system and other selected features using standard light microscopy (LM) and an internally developed VM system, and (ii) the interchangeability of LM and VM. Two uro-pathologists reviewed 413 cores from 60 Swedish men diagnosed with non-metastatic prostate cancer 1998-2014.

Transplantation of Human Neural Precursor Cells Reverses Syrinx Growth in a Rat Model of Post-Traumatic Syringomyelia.

Posttraumatic syringomyelia (PTS) is a serious condition of progressive expansion of spinal cord cysts, affecting patients with spinal cord injury years after injury. To evaluate neural cell therapy to prevent cyst expansion and potentially replace lost neurons, we developed a rat model of PTS. We combined contusive trauma with subarachnoid injections of blood, causing tethering of the spinal cord to the surrounding vertebrae, resulting in chronically expanding cysts.

Expression of Pluripotency Markers in Nonpluripotent Human Neural Stem and Progenitor Cells.

Nonpluripotent neural progenitor cells (NPCs) derived from the human fetal central nervous system were found to express a number of messenger RNA (mRNA) species associated with pluripotency, such as NANOG, REX1, and OCT4. The expression was restricted to small subpopulations of NPCs. In contrast to pluripotent stem cells, there was no coexpression of the pluripotency-associated genes studied.

Neuroprotective effects of human spinal cord-derived neural precursor cells after transplantation to the injured spinal cord.

To validate human neural precursor cells (NPCs) as potential donor cells for transplantation therapy after spinal cord injury (SCI), we investigated the effect of NPCs, transplanted as neurospheres, in two different rat SCI models. Human spinal cord-derived NPCs (SC-NPCs) transplanted 9 days after spinal contusion injury enhanced hindlimb recovery, assessed by the BBB locomotor test. In spinal compression injuries, SC-NPCs transplanted immediately or after 1 week, but not 7 weeks after injury, significantly improved hindlimb recovery compared to controls.
