AIM: Cinitapride (CIN) is a benzamide-derived molecule used for the treatment of gastroesophageal reflux and dyspepsia. Its pharmacokinetics are controversial due to the use of supratherapeutic doses and the lack of sensitive methodology. Therefore, a sensitive and accurate micromethod was developed for its quantitation in human plasma. RESULTS: CIN was extracted from 300 µl of heparinized plasma by liquid-liquid extraction using cisapride as internal standard, and analyzed with an ultra performance liquid chromatograph employing positive multiple-reaction monitoring-MS...

We previously reported that insufficiency of antithrombin III (ATIII), the major anti-coagulation molecule in vivo, exacerbated renal ischemia-reperfusion injury in animal models and possibly humans. In the present study, we investigated the relationship between ATIII level and contrast induced nephropathy (CIN) in patients and examined therapeutic effect of ATIII on CIN in Sprague-Dawley rats. Patients with low ATIII activity presented a higher incidence of acute kidney injury (AKI) following coronary angiography...

Carcinosarcoma and adenoid basal carcinoma (ABC) are both rare lesions in uterine cervix. There were only 5 cases of cervical carcinosarcoma combined with ABC and/without cervical intraepithelial neoplasia (CIN) reported in English literature. These limited studies showed that there was a strong association between HPV, carcinosarcoma, ABC and CIN, suggesting a common etiology for these lesions. Here, we present the case of a 65-year-old woman with cervical carcinosarcoma combined with ABC and CIN III. However, HPV-16, 18, 31 and 33 was negative in the cervical carcinosarcoma tissue by in situ hybridization detection...

PURPOSE: Besides cervical cancer, HPV infection is linked to a multitude of diseases in both males and females, suggesting that vaccination programmes should be re-evaluated, with a judicious assessment made of the disease burden stratified by sex, age, and genotype. Projections of burden into the near future are also needed to provide a benchmark for evaluating the impact of vaccination programmes, and to assess the need for scaling-up preventive measures. METHODS: Using the disability-adjusted life-years (DALY) measure, we estimated the total HPV-associated disease burden in the Netherlands...

Large-scale, massively parallel sequencing of human cancer samples has revealed tremendous genetic heterogeneity within individual tumors. Indeed, tumors are composed of an admixture of diverse subpopulations-subclones-that vary in space and time. Here, we discuss a principal driver of clonal diversification in cancer known as chromosomal instability (CIN), which complements other modes of genetic diversification creating the multilayered genomic instability often seen in human cancer. Cancer cells have evolved to fine-tune chromosome missegregation rates to balance the acquisition of heterogeneity while preserving favorable genotypes, a dependence that can be exploited for a therapeutic benefit...

Chromosomal instability (CIN) is classically defined as an increase in the rate at which numerical or structural chromosomal aberrations are acquired in a cancer cell. The number of somatic copy number abnormalities (CNAs) revealed by high resolution genomic array can be considered as a surrogate marker for CIN, but several points, related to sample processing and data analysis, need to be standardized. In this work we analyzed 51 CRC samples and matched normal mucosae by whole genome SNP arrays and compared different bioinformatics tools in order to identify broad (>25% of a chromosomal arm) and focal somatic copy number abnormalities (BCNAs and FCNAs respectively)...

S100A7 is an EF-hand calcium-binding protein that has been suggested to be implicated in cell proliferation, migration, invasion and tumor metastasis. However, its role in cervical cancer has not yet been fully clarified. The present study used immunohistochemistry analysis of S100A7 in clinical specimens of cervical cancer to show that S100A7 expression was significantly upregulated in cervical cancer tissues compared with normal cervical tissues and S100A7 expression in high grade cervical intraepithelial neoplasm (CIN) was significantly higher than cervical cancer...

BACKGROUND: Several observational studies reported that Oseltamivir (Tamiflu) reduced mortality in infected and hospitalized patients. Due to the restriction of observation to hospital stay and time-dependent treatment assignment, such findings were prone to common types of survival bias (length, time-dependent and competing risk bias). METHODS: British hospital data from the FLU-CIN study group were used which included 1391 patients with confirmed pandemic influenza A/H1N1 2009 infection...

AIMS: Cystatin C have shown to be a renal function parameter with higher sensitivity and specificity than serum creatinine. In tubular diseases, cystatin C degradation and an increase in its urinary elimination would be observed. We have tried to define if different kinds of kidney diseases may significantly affect the serum levels of cystatin C. DESIGN AND METHODS: Four hundred and four patients were studied: 249 men and 155 women, mean age was 64.3±10.1 years...

Neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C represent early renal injury markers for contrast-induced nephropathy (CIN). Baseline parameters such as type and quantity of contrast, patient preparation, renal function status, and diabetes mellitus (DM) are known to affect the response of the kidney to contrast-induced injury. This study was taken up to know the biomarker response to contrast administration in 58 diabetic and 59 nondiabetic male patients with same baseline parameters and baseline serum creatinine <1...

INTRODUCTION: Conservative treatments including cold knife cone biopsy (CKC) or loop electrosurgical excision procedure (LEEP) are fertility-preserving alternatives to hysterectomy. The risks of persistent cervical neoplasia in women with negative surgical margins following conservative treatment of adenocarcinoma-in-situ (AIS) are uncertain. This study aims to investigate the risk of persistent or recurrent cervical neoplasia (AIS, adenocarcinoma and/or high-grade cervical squamous intraepithelial neoplasia (CIN)) and compliance with follow-up recommendations in conservatively treated women with AIS and negative histopathological margins...

Asymmetric dimethylarginine (ADMA) is a competitive inhibitor of the nitric oxide (NO)-synthase and a biomarker of endothelial dysfunction (ED). ED plays an important role in the pathogenesis of contrast-induced nephropathy (CIN). The aim of our study was to evaluate serum ADMA concentration as a biomarker of an acute renal damage during the follow-up of 90 days after contrast medium (CM) application.Blood samples were obtained from 330 consecutive patients with diabetes mellitus or mild renal impairment immediately before, 24 and 48 hours after the CM application for coronary angiography...

We evaluated whether primary percutaneous coronary intervention (pPCI) during off-hours is related to an increased incidence of contrast-induced nephropathy (CIN). We retrospectively analyzed the incidence of CIN mortality among 2552 patients with consecutive ST-segment elevation myocardial infarction treated with pPCI during regular hours (weekdays 8:00 am to 5:00 pm) and off-hours (weekdays 5:01 pm to 7:59 am, weekends and holidays). Patients in the off-hour group were more frequently admitted with acute heart failure symptoms (16...

OBJECTIVE: Contrast induced nephropathy (CIN) is a result of injury to the proximal tubules. The incidence of CIN is around 11% for imaging done in the acute care setting. We aim to analyze the metabolic patterns in the urine, before and after dosing with intravenous contrast for computed tomography (CT) imaging of the chest, to determine if metabolomic changes exist in patients who develop CIN. METHODS: A convenience sample of high risk patients undergoing a chest CT with intravenous contrast were eligible for enrollment...

Low rates of chromosomal instability (CIN) are weakly tumor promoting, whereas high rates of CIN cause cell death and tumor suppression. In this context, Sansregret and colleagues show that one mechanism to restrain excessive CIN in tumor cells and increase fitness is through mutations in the anaphase promoting complex/cyclosome. This serves to delay mitotic progression and decrease the rate of chromosome missegregation. Cancer Discov; 7(2); 134-6. ©2017 AACRSee related article by Sansregret et al., p. 218...
