BACKGROUND: In spite of significant improvement after multi-modality treatment, prognosis of most patients with glioblastoma remains poor. Standard clinical prognostic factors (age, gender, extent of surgery and performance status) do not clearly predict long-term survival. The aim of this case-control study was to evaluate immuno-histochemical and genetic characteristics of the tumour as additional prognostic factors in glioblastoma. PATIENTS AND METHODS: Long-term survivor group were 40 patients with glioblastoma with survival longer than 30 months...

To assess at 3 years bacillus Calmette-Guerin (BCG) maintenance treatment for NMIBC using one-third dose schedule and fewer instillations every 3 or 6 months. This was a phase III randomized study including patients with intermediate-risk or high-risk NMIBC, who received, after a full-dose induction schedule, three-weekly instillations of one-third dose BCG every 6 months (group I) and two-weekly instillations every 3 months (group II) during 3 years. We assessed oncological efficacy, BCG side effects, leukocyturia, and prostate-specific antigen...

Iron is a tightly regulated micronutrient with no physiologic means of elimination and is necessary for cell division in normal tissue. Recent evidence suggests that dysregulation of iron regulatory proteins may play a role in cancer pathophysiology. We use public data from The Cancer Genome Atlas (TCGA) to study the association between survival and expression levels of 61 genes coding for iron regulatory proteins in patients with World Health Organization Grade II-III gliomas. Using a feature selection algorithm we identified a novel, optimized subset of eight iron regulatory genes (STEAP3, HFE, TMPRSS6, SFXN1, TFRC, UROS, SLC11A2, and STEAP4) whose differential expression defines two phenotypic groups with median survival differences of 52...

INTRODUCTION: A 42-year-old woman presented with urinary incontinence 9 years after the last of four vaginal deliveries. She had also had one Caesarean section. Immediately after the last delivery, she presented with haematuria, which resolved within a few hours, but the drain remained prophylactically for 7 days. Nine years later, she was referred to a specialist hospital. METHOD: The patient presented with continuous urinary incontinence, and physical examination revealed a loss of urine from the vagina, the latter confirmed by a methylene blue test showing loss of urine from the uterine cervix...

STUDY QUESTION: What are the primary causes of severe male factor infertility? SUMMARY ANSWER: Although 40% of all patients showed primary causes of infertility, which could be subdivided into three groups based on the severity of their effect, ~75% of oligozoospermia cases remained idiopathic. WHAT IS KNOWN ALREADY: There are few large-scale epidemiological studies analyzing the causes of male factor infertility. STUDY DESIGN, SIZE, DURATION: A prospective clinical-epidemiological study was conducted at the Andrology Centre, Tartu University Hospital between 2005 and 2013, recruiting male partners of couples failing to conceive a child for over ≥12 months...

The role of mitochondrial DNA for the evolution of life-history traits remains debated. We examined mitonuclear effects on the activity of the multisubunit complex of the electron transport chain (ETC) involved in oxidative phosphorylation (OXPHOS) across lines of the seed beetle Acanthoscelides obtectus selected for a short (E) or a long (L) life for more than >160 generations. We constructed and phenotyped mitonuclear introgression lines, which allowed us to assess the independent effects of the evolutionary history of the nuclear and the mitochondrial genome...

OBJECTIVES: Urinary calculi rarely occur in renal transplant. However, because of peculiarities shown with renal allografts, a prudent approach is necessary to prevent further complications or even graft failure. There are no well-established guidelines for uro?ithiasis in renal grafts regarding adequate therapy selection. In the present article, different therapeutic interventions are discussed, including in 1 case a pyelovesicostomy as an uncommon intervention. MATERIALS AND METHODS: We retrospectively reviewed data of 1115 patients who underwent renal transplant between January 2002 and December 2014 for urolithiasis in different databases...

Inducing selective or targeted cell apoptosis without affecting large number of neighbouring cells remains a challenge. A plausible method for treatment of posterior capsular opacification (PCO) due to remaining lens epithelial cells (LECs) by reactive chemistry induced by localized single electrode microplasma discharge at top of a needle-like glass electrode with spot size ~3 μm is hereby presented. The focused and highly-localized atmospheric pressure microplasma jet with electrode discharge could induce a dose-dependent apoptosis in selected and targeted individual LECs, which could be confirmed by real-time monitoring of the morphological and structural changes at cellular level...

Despite great interest, two randomised controlled trials (RCTs) of cytoreductive nephrectomy in the tyrosine kinase inhibitor setting in metastatic renal cell carcinoma have either closed early (SURTIME) or are recruiting very slowly (CARMENA) after 7 yr. Challenges in RCT delivery in uro-oncologic surgery are many. Multiple steps are needed to ensure strong recruitment to trials addressing important urologic cancer questions. Feasibility/pilot studies are key stepping stones towards successful delivery of surgical RCTs...

The objective of this study was to evaluate the independent associations between nausea, vomiting, fatigue and health-related quality of life of women in early pregnancy in the Generation R study, which is a prospective mother and child cohort. Analyses were based on 5079 women in early pregnancy in the Rotterdam area, the Netherlands. The information on nausea, vomiting and fatigue in the previous three months was measured in the questionnaire at enrollment, as well as potential confounders (i.e., maternal/gestational age, ethnic background, educational level, parity, marital status, body mass index, tobacco and alcohol use, chronic/infectious conditions, uro-genital conditions/symptoms, sleep quality, headache, anxiety, and depression)...

A correlation between the absolute configuration and chiroptical properties of non-racemic 1,6,7-trisubstituted 2,3-dihydro-1H,5H-pyrazolo[1,2-a]pyrazoles was studied. A series of 16 novel representatives were prepared by Cu-catalyzed [3+2]-cycloadditions of racemic (Z)-2-benzylidene-5-oxopyrazolidin-2-ium-1-ides to tert-butyl (S)-(3-oxopent-4-yn-2-yl)carbamate, and their structures were determined by NMR, VCD, ECD, and X-ray diffraction. A clear correlation between the sign of specific rotation and configuration at position C(1) allows for easy determination of the absolute configuration of 1,6,7-trisubstituted 2,3-dihydro-1H,5H-pyrazolo[1,2-a]pyrazoles by ECD and NMR...

INTRODUCTION AND OBJECTIVES: Nephroureterectomy remains the gold standard treatment option for upper tract tumors. However, segmental ureterectomy may be another option in patients with single kidney, borderline renal function or high medical comorbidities. The aim of this video is to assess the feasibility of robotic surgery as a minimally invasive technique in treatment of a high comorbid patient with ureteric tumor. MATERIALS AND METHODS: Eighty-year old male patient, with a medical history of chronic hypertensive and uncontrolled Diabetes Mellitus, was referred to our department for treatment of ureteric tumor...

Mitochondria play a key role in ageing. The pursuit of genes that regulate variation in lifespan and ageing have shown that several nuclear-encoded mitochondrial genes are important. However, the role of mitochondrial-encoded genes (mtDNA) is more controversial and our appreciation of the role of mtDNA for the evolution of lifespan is limited. We use replicated lines of seed beetles that have been artificially selected for long or short life for >190 generations, now showing dramatic phenotypic differences, to test for a possible role of mtDNA in the divergent evolution of ageing and lifespan...

PURPOSE: The capture of adequate treatment outcomes and quality of life (QOL) of advanced breast cancer patients in clinical routine represents a great challenge. Patient-reported outcomes (PROs) are data elements directly reported by patients about experiences with care, including symptoms, functional status, or quality of life. There is growing interest in the medical community for the evaluation and implementation of PROs of adverse events (PRO-AEs). Recent interest in PROs in health care has evolved in the context of patient centeredness...

Phospholamban (PLN) plays a central role in Ca(2+) homeostasis in cardiac myocytes through regulation of the sarco(endo)plasmic reticulum Ca(2+)-ATPase 2A (SERCA2A) Ca(2+) pump. An inherited mutation converting arginine residue 9 in PLN to cysteine (R9C) results in dilated cardiomyopathy (DCM) in humans and transgenic mice, but the downstream signaling defects leading to decompensation and heart failure are poorly understood. Here we used precision mass spectrometry to study the global phosphorylation dynamics of 1,887 cardiac phosphoproteins in early affected heart tissue in a transgenic R9C mouse model of DCM compared with wild-type littermates...

This review aims to discuss the current state-of-the-art of sentinel node (SN) mapping in urological malignancies. The principles and methodological aspects of lymphatic mapping and SN biopsy in urological malignancies are reviewed. Literature search was restricted to English language. The references of the retrieved articles were examined to identify additional articles. The review also includes meta-analyses published in the past 5 years. SN biopsy for penile cancer is recommended by the European Association of Urology as the preferred staging tool for clinically node-negative patients with at least T1G2 tumours (level of evidence 2a, Grade B)...
