Small peptide CSF fingerprint of amyotrophic lateral sclerosis.

Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by abnormal protein aggregation in the motor neurons. Present and earlier proteomic studies to characterize peptides in cerebrospinal fluid (CSF) associated with motoneuron pathology did not target low molecular weight proteins and peptides. We hypothesized that specific changes in CSF peptides or low molecular weight proteins are significantly altered in ALS, and that these changes may support deciphering molecular pathophysiology and even guide approaches towards therapeutic interventions.

Enhancing neuroimaging genetics through meta-analysis for Tourette syndrome (ENIGMA-TS): A worldwide platform for collaboration.

Tourette syndrome (TS) is characterized by multiple motor and vocal tics, and high-comorbidity rates with other neuropsychiatric disorders. Obsessive compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), autism spectrum disorders (ASDs), major depressive disorder (MDD), and anxiety disorders (AXDs) are among the most prevalent TS comorbidities. To date, studies on TS brain structure and function have been limited in size with efforts mostly fragmented.

Verifying Death Reports in the Platelet Inhibition and Patient Outcomes (PLATO) Trial.

Background: Excess vascular deaths in the PLATO trial comparing ticagrelor to clopidogrel have been repeatedly challenged by the Food and Drug Administration (FDA) reviewers and academia. Based on the Freedom of Information Act, BuzzFeed won a court order and shared with us the complete list of reported deaths for the ticagrelor FDA New Drug Application (NDA) 22-433. This dataset was matched against local patient-level records from PLATO sites monitored by the sponsor.

INPART - a psycho-oncological intervention for partners of patients with haemato-oncological disease - study protocol.

Background: Suffering from cancer confronts both the patient and their partner with a number of psychosocial challenges in various aspects of their life. These challenges may differentially impact on quality of life, coping ability and compliance to treatment. This especially holds true for haemato-oncological diseases.

Calgranulin A (S100A8) Immunostaining: A Future Candidate for Risk Assessment in Patients with Non-Muscle-Invasive Bladder Cancer (NMIBC).

Introduction: There is an urgent need to identify patients with bladder cancer (BC) who are at high risk of recurrence or progression. Calgranulin A is a strong marker for muscle-invasive or advanced BC and recent studies have shown its potential for identifying patients at risk even in non-muscle-invasive bladder cancer (NMIBC). The present study examines risks of recurrence and progression dependent on immunostaining with calgranulin A in NMIBC.

Rho GDP dissociation inhibitor-β in renal cell carcinoma.

Rho GDP dissociation inhibitor-β (ARHGDIB) is an important mediator of cell signaling. The expression of ARHGDIB is associated with tumor growth and metastasis in a variety of non-genitourinary cancers; however, the role of ARHGDIB in renal cell carcinoma (RCC) has not yet been evaluated. In the present study, tissue samples from 105 patients undergoing surgery for RCC were obtained.

Surgical therapy of prostatitis: a systematic review.

Purpose: The clinical term "prostatitis" refers to a clinical syndrome defined by the following 4 distinct entities: acute bacterial prostatitis (category 1), chronic bacterial prostatitis (category 2), chronic prostatitis/chronic pelvic pain syndrome (category 3), and asymptomatic prostatitis (category 4) The etiology of the chronic forms is still not fully understood and choice of therapy is often debated. The objective of this systematic review is to collect evidence on the surgical treatment of the chronic form of prostatitis and to evaluate its clinical implication.

Methods: We performed a systematic literature search and identified 6683 relevant publications, of which 16 were included in the review.

True Incidence of Gleason 6 Pathology in Patients with Metastatic Castration Resistant Prostate Cancer (mCRPC).

Introduction: Recent evidence from histology studies regarding random prostate biopsies hint toward a relationship between higher biopsy Gleason score and the development of metastatic castration resistant prostate cancer (mCRPC). However, prostate biopsy underestimates final pathology in about one-third of patients. We evaluated the final whole gland pathology from radical prostatectomy exclusively in order to assess the true risk of progressing to the mCRPC state for patients with confirmed Gleason ≤6 prostate cancer.

Novel therapeutic options for second-line therapy in metastatic renal cell carcinoma.

Metastatic renal cell carcinoma (mRCC) has gained a variety of therapeutic options since the introduction of targeted therapy, starting in 2007. The basic molecular mechanisms included predominantly the targeting of vascular endothelial growth factor or the inhibition of the mammalian target of rapamycin. Recently, results from two randomized controlled trials, the CheckMate-25 and the METEOR trial, regarding therapy for RCC in the second-line setting have been published.

Prediction of Perioperative Death Following Surgery for Renal Cell Carcinoma with Vein Involvement: A Retrospective Study.

Introduction: Advanced renal cell carcinoma (RCC) shows a propensity for extending into the tributaries of the renal veins, which poses a notable surgical challenge. In this study we addressed the question as to whether patients with RCC and vein involvement can be identified as having a significant risk of immediate death associated with surgery preoperatively.

Materials And Methods: A total of 118 patients with RCC and vein involvement from February 1999 until November 2012 were evaluated.

Clinical effects of phosphodiesterase 3A mutations in inherited hypertension with brachydactyly.

Autosomal-dominant hypertension with brachydactyly is a salt-independent Mendelian syndrome caused by activating mutations in the gene encoding phosphodiesterase 3A. These mutations increase the protein kinase A-mediated phosphorylation of phosphodiesterase 3A resulting in enhanced cAMP-hydrolytic affinity and accelerated cell proliferation. The phosphorylated vasodilator-stimulated phosphoprotein is diminished, and parathyroid hormone-related peptide is dysregulated, potentially accounting for all phenotypic features.

PDE3A mutations cause autosomal dominant hypertension with brachydactyly.

Cardiovascular disease is the most common cause of death worldwide, and hypertension is the major risk factor. Mendelian hypertension elucidates mechanisms of blood pressure regulation. Here we report six missense mutations in PDE3A (encoding phosphodiesterase 3A) in six unrelated families with mendelian hypertension and brachydactyly type E (HTNB).

The Fuhrman grading system has no prognostic value in patients with nonsarcomatoid chromophobe renal cell carcinoma.

The prognostic value of the Fuhrman nuclear grading system has been questioned for chromophobe renal cell carcinoma (chRCC) because this subtype frequently displays nuclear and nucleolar pleomorphism. The present study reevaluates this grading system in a series of patients with nonsarcomatoid chRCC. We identified 176 patients (3.

Clinical behavior of chromophobe renal cell carcinoma is less aggressive than that of clear cell renal cell carcinoma, independent of Fuhrman grade or tumor size.

Chromophobe renal cell carcinoma (chRCC) is the third most common subtype of RCC, after clear cell (ccRCC) and papillary RCC. Its lower incidence and frequent exclusion from clinical trials might be why chRCC characteristics have not been extensively studied. The aim of our study was to examine tumor characteristics and long-term prognosis of chRCC compared to ccRCC.

Galectin-1 and Galectin-3 mRNA expression in renal cell carcinoma.

Background: Galectins are known to regulate cell differentiation and growth as well as cell adhesion and apoptosis. Galectins have been discussed as possible prognosticators for survival in renal cell cancer (RCC) and other urological tumors. They might also play an emerging role as possible new marker-proteins for RCC.

Small renal cell carcinomas--how dangerous are they really? Results of a large multicenter study.

Aim Of The Study: Modern diagnostic ultrasound and cross-sectional imaging has enabled the detection of increasing numbers of renal tumours. The aim of this study was to investigate the tumour- and patient-specific characteristics and prognosis of small renal cell carcinomas (RCCs) after surgical resection.

Methods: The study included 2197 patients who underwent surgical resection of histologically confirmed RCC ⩽ 4 cm between 1990 and 2011.

Incidence and long-term prognosis of papillary compared to clear cell renal cell carcinoma--a multicentre study.

Aim Of The Study: Papillary renal cell carcinoma (pRCC) is the second most common subtype of RCC after the conventional clear cell type (cRCC). However, its characteristics and prognosis have been less intensively investigated. The aim of our study was to examine the tumour characteristics and long-term prognosis of pRCC compared to clear cell RCC (cRCC).

Does obesity influence the prognosis of metastatic renal cell carcinoma in patients treated with vascular endothelial growth factor-targeted therapy?

Background: Obesity increases the risk for renal cell carcinoma (RCC). However, it has only recently been identified as an independent positive prognostic factor for localized RCC.

Objective: To determine whether obesity influences long-term prognosis in metastatic RCC patients receiving vascular endothelial growth factor-targeted therapy.

Is there a need to further subclassify pT2 renal cell cancers as implemented by the revised 7th TNM version?

Background: The recently modified TNM classification of renal cell carcinoma (RCC) (7th edition) has implemented a subdivision of pT2 tumours into stage pT2a (>7 or ≤10 cm) versus pT2b disease (>10 cm).

Objective: Our aim was to evaluate whether this subdivision of pT2 RCC is justified due to a clinical prognosis divergence between the two groups (pT2a vs pT2b)

Design, Setting, And Participants: In total, 5122 patients were subjected to either radical nephrectomy or nephron-sparing surgery at three centres in Germany (University Hospitals of Hannover, Homburg/Saar, and Marburg). Patients were reclassified into stage pT2a and pT2b according to the maximum tumour diameter as suggested by the 7th revised version of the TNM classification system.

Present state of target therapy for disseminated renal cell carcinoma.

Both experimental and clinical researches focusing on advanced kidney cancer have increased continuously since the successful introduction of targeted therapy in the treatment of advanced metastatic renal cell carcinoma. Being refractory to conventional hormone therapy, chemotherapy or radiotherapy, renal cell carcinoma has become a model tumor for the development and evaluation of diverse novel targeted drugs. This review highlights currently available agents and summarizes evidence-based data regarding their effectiveness in metastatic renal cell carcinoma.

Altered expression of Akt signaling pathway parameters in prostate needle biopsies derived from benign, adjacent and cancerous tissue.

PTEN, p-Akt and p27kip1 are known to be altered in prostate cancer. The aim of the present study was to determine the addition of molecular markers to a classical histopathological approach to enhance the sensitivity in detection of malignant or premalignant lesions within prostatic biopsies. Forty-two fine needle biopsies from malignant, tumor adjacent and benign areas were obtained from 14 patients scheduled for a prostatic biopsy.

Cell therapy for acute myocardial infarction.

The infarcted heart heals by scar formation, and large myocardial infarctions typically result in heart failure. Although adult stem cells with the capacity to transform into various cardiac cell types and to secrete cardioprotective cytokines have been identified, endogenous repair mechanisms in the adult heart are not sufficient for meaningful tissue regeneration. These observations, however, suggest that it may be feasible to develop interventions aimed at enhancing these processes, and to promote functional, and eventually, structural recovery of the infarcted heart.

Haeme oxygenase promotes progenitor cell mobilization, neovascularization, and functional recovery after critical hindlimb ischaemia in mice.

Aims: Neovascularization is an important element of long-term functional recovery during chronic ischaemia. We postulated that haeme oxygenase (HO) is required for progenitor cell recruitment, neovascularization, and blood flow recovery after critical hindlimb ischaemia (HLI).

Methods And Results: The femoral artery was ligated in FVB/N mice proximal to its superficial and deep branches.

Growth differentiation factor 15 for risk stratification and selection of an invasive treatment strategy in non ST-elevation acute coronary syndrome.

Background: An invasive treatment strategy improves outcome in patients with non-ST-elevation acute coronary syndrome at moderate to high risk. We hypothesized that the circulating level of growth differentiation factor 15 (GDF-15) may improve risk stratification.

Methods And Results: The Fast Revascularization during InStability in Coronary artery disease II (FRISC-II) trial randomized patients with non-ST-elevation acute coronary syndrome to an invasive or conservative strategy with a follow-up for 2 years.
