Sampling for Collection of Central Line–Day Denominators in Surveillance of Healthcare-Associated Bloodstream Infections. Infect Control Hosp Epidemiol 2016; 27:338-42. [PMID: 16622809 DOI: 10.1086/503338] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2005] [Accepted: 12/08/2005] [Indexed: 11/03/2022]
Abstract
Objective.To determine the feasibility of estimating the number of central line-days at a hospital from a sample of months or individual days in a year, for surveillance of healthcare-associated bloodstream infections.Design.We used data reported to the National Nosocomial Infections Surveillance system in the adult and pediatric intensive care unit component for 1995-2003 and data from a sample of hospitals' daily counts of device use for 12 consecutive months. We calculated the percentile error as the central line-associated bloodstream infection percentile based on rates per line-days minus the percentile based on rates per estimated line-days.Setting and Participants.A total of 247 hospitals were used for sampling whole months and 12 hospitals were used for sampling individual days.Results.For a 1-month sample of central line–days data, the median percentile error was 3.3 (75th percentile, 7.9; 90th percentile, 15.4). The percentile error decreased with an increase in the number of months sampled. For a 3-month sample, the median percentile error was 1.4 (75th percentile, 4.3; 95th percentile, 8.3). Sampling individual days throughout the year yielded lower percentile errors than sampling an equivalent fraction of whole months. With 1 weekday sampled per week, the median percentile error ranged from 0.65 to 1.40, and the 90th percentile ranged from 2.8 to 5.0. Thus, for 90% of units, collecting data on line-days once a week provides an estimate within ± 5 percentile points of the true line-day rate.Conclusion.Sample-based estimates of central line-days can yield results that are acceptable for surveillance of healthcare-associated bloodstream infections.

Abstract
Partial trisomy of the 10q region was originally reported in 1979 [1]. For 25 years, the diagnosis was made microscopically based on large, visible insertions in the region identified by karyotype analysis. Previous case reports have included both unbalanced translocations and large duplications/insertions in the 10q region [2]. Probands with partial trisomy 10q syndrome often have an abnormal phenotype that may include developmental delay [3-5], craniofacial abnormalities [3, 5], talipes (clubfoot) [2], microcephaly [2-4], or congenital heart disease [2-6]. Prenatal diagnoses by karyotype have been made following ultrasound diagnosis of sacrococcygeal teratoma [7], renal pyelectasis [3, 8-10], and other fetal abnormalities [4]. In this case, we report the first prenatal diagnosis of partial trisomy 10q (10q22.3-10q23.2) with a normal karyotype and an abnormal chromosomal microarray analysis (CMA). This is the smallest copy number variant (CNV) (7.5 Mb) in the 10q22.3-10q23.2 regions yet reported.

Comparison of the prognostic value of measures of the tumor inflammatory cell infiltrate and tumor-associated stroma in patients with primary operable colorectal cancer. Oncoimmunology 2016; 5:e1098801. [PMID: 27141369 DOI: 10.1080/2162402x.2015.1098801] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2015] [Revised: 09/15/2015] [Accepted: 09/17/2015] [Indexed: 12/19/2022] Open
Abstract
The aim of the present study was to compare the clinical utility of two measures of the inflammatory cell infiltrate - a H&E-based assessment of the generalized inflammatory cell infiltrate (the Klintrup-Mäkinen (KM) grade), and an immunohistochemistry-based assessment of combined CD3+ and CD8+ T-cell density (the "Immunoscore"), in conjunction with assessment of the tumor stroma percentage (TSP) in patients undergoing resection of stage I-III colorectal cancer (CRC). Two hundred and forty-six patients were identified from a prospectively maintained database of CRC resections in a single surgical unit. Assessment of KM grade and TSP was performed using full H&E sections. CD3+ and CD8+ T-cell density was assessed on full sections and the Immunoscore calculated. KM grade and Immunoscore were strongly associated (p < 0.001). KM grade stratified cancer-specific survival (CSS) from 88% to 66% (p = 0.002) and Immunoscore from 93% to 61% (p < 0.001). Immunoscore further stratified survival of patients independent of KM grade from 94% (high KM, Im4) to 60% (low KM, Im0/1). Furthermore, TSP stratified survival of patients with a weak inflammatory cell infiltrate (low KM: from 75% to 47%; Im0/1: from 71% to 38%, both p < 0.001) but not those with a strong inflammatory infiltrate. On multivariate analysis, only Immunoscore (HR 0.44, p < 0.001) and TSP (HR 2.04, p < 0.001) were independently associated with CSS. These results suggest that the prognostic value of an immunohistochemistry-based assessment of the inflammatory cell infiltrate is superior to H&E-based assessment in patients undergoing resection of stage I-III CRC. Furthermore, assessment of the tumor-associated stroma, using TSP, further improves prediction of outcome.

Abstract
Objectives To assess and compare patient perceived quality of osteoarthritis (OA) management in primary healthcare in Denmark, Norway, Portugal and the UK. Methods Participants consulting with clinical signs and symptoms of knee OA were identified in 30 general practices and invited to complete a cross-sectional survey including quality indicators (QI) for OA care. A QI was considered as eligible if the participant had checked ‘Yes’ or ‘No’, and as achieved if the participant had checked ‘Yes’ to the indicator. The median percentage (with IQR and range) of eligible QIs achieved by country was determined and compared in negative binominal regression analysis. Achievement of individual QIs by country was determined and compared using logistic regression analyses. Results A total of 354 participants self-reported QI achievement. The median percentage of eligible QIs achieved (checked ‘Yes’) was 48% (IQR 28%, 64%; range 0–100%) for the total sample with relatively similar medians across three of four countries. Achievement rates on individual QIs showed a large variation ranging from 11% (referral to services for losing weight) to 67% (information about the importance of exercise) with significant differences in achievement rates between the countries. Conclusions The results indicated a potential for improvement in OA care in all four countries, but for somewhat different aspects of OA care. By exploring these differences and comparing healthcare services, ideas may be generated on how the quality might be improved across nations. Larger studies are needed to confirm and further explore the findings.

Age-related sperm DNA methylation changes are transmitted to offspring and associated with abnormal behavior and dysregulated gene expression. Mol Psychiatry 2015; 20:995-1001.

Abstract
Advanced paternal age (APA) has been shown to be a significant risk factor in the offspring for neurodevelopmental psychiatric disorders, such as schizophrenia and autism spectrum disorders. During aging, de novo mutations accumulate in the male germline and are frequently transmitted to the offspring with deleterious effects. In addition, DNA methylation during spermatogenesis is an active process, which is susceptible to errors that can be propagated to subsequent generations. Here we test the hypothesis that the integrity of germline DNA methylation is compromised during the aging process. A genome-wide DNA methylation screen comparing sperm from young and old mice revealed a significant loss of methylation in the older mice in regions associated with transcriptional regulation. The offspring of older fathers had reduced exploratory and startle behaviors and exhibited similar brain DNA methylation abnormalities as observed in the paternal sperm. Offspring from old fathers also had transcriptional dysregulation of developmental genes implicated in autism and schizophrenia. Our findings demonstrate that DNA methylation abnormalities arising in the sperm of old fathers are a plausible mechanism to explain some of the risks that APA poses to resulting offspring.

Abstract
A retrospective epidemiological case-control study was performed in Karachi, Pakistan, from January to April 2013. The owners of 217 dairy cattle and buffalo farms from six different locations in Karachi were interviewed. The aim of the study was to identify risk factors associated with the presence of haemorrhagic septicaemia (HS). Farms with a history of at least one instance of sudden death in a dairy animal during 2012 and a positive clinical HS diagnosis (made by local veterinarians) were defined as cases. Farms having no history of sudden deaths in 2012 were defined as controls. Univariable analyses were initially conducted, and factors with P ≤ 0.25 were offered to a multivariable logistic regression model to identify putative risk factors. The final multivariable logistic model contained five factors. Vaccination was found to be a protective factor (OR = 0.22) along with the length of time cattle were kept on farm (months). For every extra month cattle were kept, the odds of HS disease were reduced by a factor of 0.9. In contrast, for every extra animal in a herd, the risk of infection increased by a factor of 1.01. Supplying underground water and the presence of foot and mouth disease on the farm increased the risk by 2.90 and 2.37, respectively. To understand the epidemiology of HS in Karachi dairy herds, more in-depth research is required to study the risk and protective factors identified in this survey and to evaluate risk mitigation strategies, where possible.

Abstract
PURPOSE Chemotherapy-induced diarrhoea (CID) has a significant impact. A medicinal food product (ReCharge) containing iron-saturated lactoferrin and anhydrous milk fat reduces the detrimental effects of chemotherapy on the gut in animals. We report results of a randomised blinded placebo-controlled phase IIb trial investigating the efficacy and safety of ReCharge in preventing CID. METHODS Eligible patients were adults due to start the first cycle of a 2- or 3-week-cycle chemotherapy regimen, had an Eastern Cooperative Oncology Group (ECOG) status of 3 or less, had adequate haematological, liver and renal function and provided written informed consent. Patients (197) were randomised to ReCharge or placebo. They consumed 100-g study product for 2 weeks before and 6 weeks after starting chemotherapy, completed daily diaries for 8 weeks and attended clinic visits until 12 weeks (2-week cycles) or 14 weeks (3-week cycles). The primary outcome was days with CID. RESULTS The mean number of days with diary-recorded CID was marginally but not statistically significantly lower on ReCharge than placebo (-2.0, 95 % CI (-4.7 to 0.7), p = 0.2). The proportion reporting diarrhoea in the previous cycle at the clinic visit was 30 % lower (p = 0.012) on ReCharge. Missing diary data may have contributed to the discrepancy. No significant differences were found in quality of life or other adverse events. CONCLUSIONS We found no clear evidence that ReCharge reduced CID as measured by patient self-report diary. The converse finding of benefit as recorded at clinic visits and incomplete adherence to diary completion indicates that further research is required into methods for measuring CID.

Abstract
INTRODUCTION AND METHODS Malignant pleural mesothelioma (MPM) is an uncommon cancer with poor survival. We have used data collected for the UK National Lung Cancer Audit to assess current practice and to highlight regional variation in the management of mesothelioma patients, as well as to describe survival patterns in subgroups. RESULTS Our data on 8740 cases seen in hospitals in England and Wales is the largest cohort of MPM in the literature and represents approximately 80% of the total incident cases. 83% are male and median age is 73 years. Performance status is recorded in 81% and of these approximately 70% are PS 0-2. Stage is poorly recorded and unreliable in this dataset. The patient pathway is similar to lung cancer with approximately one-fifth having a non-elective referral to secondary care. A histo-cytological diagnosis is made in 87% and varies across organisations. Only 67% have anti-cancer treatment, and this also varies across organisations, but there has been an annual increase in the proportion receiving chemotherapy. Overall median survival was 9.5 months, with a 1YS of 41.4% and 3YS of 12.0%, but was strongly linked to performance status and histological subtype. Median survival also varied by cancer network from 209 days to 349 days, but appeared to increase from of 9.2 months in 2008 to 10.5 months in 2012. CONCLUSION Our data provide a large scale, detailed assessment of MPM epidemiology, treatment choices and outcomes. Incidence is increasing in line with predictions and uptake of treatments has generally mirrored publication of key MPM treatment trials, in particular increasing use of chemotherapy but low uptake of radical surgery. However, there is significant variation in care patterns and outcomes that may reflect limited expertise in area with low incidence. Initiatives to improve outcomes should include improved recording of clinical stage.

Abstract
AIMS The aim of this study was to examine the accuracy of standard magnetic resonance imaging (MRI) in the localised staging of prostate cancer in those who had undergone radical prostatectomy. PATIENTS AND METHODS The cohort consisted of 110 patients who had undergone MRI for staging of prostate cancer and subsequently underwent radical prostatectomy. T stage was analysed both on MRI and from the specimen following radical surgery. RESULTS Of the patients 57% of patients had their disease up-staged following radical surgery from preoperative MRI findings. Of those patients who had their disease up-staged following surgery, nearly 50% of patients had gone from organ confined disease at time of MRI to extra-prostatic involvement from the surgical specimen. CONCLUSION We have reported that MRI has a wide range of accuracy. Given developments in MRI technologies further work should be pursued to help in the staging of this disease for which decision to treat is difficult.

Abstract
Endoscope design is at the intersection of many disciplines, including robot design, computer science, material science, and medical devices. When considering design features, it is important to ensure that the device safely navigates the patient's body and, once in position, performs the task required by the surgeon. Whether surgical access is achieved through existing orifices or by small incisions, the goal is to provide the surgeon with a stable platform within the patient from which to cut, suture, and grasp, while transmitting a clear image. The device described in this article can generate force at the tip of the snakebot in any direction without pressing against interstitial tissue to redirect the applied force.

Abstract
A device comprising a filter attached to a vacuum cleaner was purpose-built to sample rust spores from three potentially high-risk pathways in Australia: passengers, fresh flowers, and sea cargo. The proportion of spores recovered from eight surfaces comparable with those on each pathway (cotton, denim, roses, carnations, chrysanthemums, wood, plastic, and metal) was estimated in the laboratory. Spore recovery percentages were highest for denim clothing (61% Puccinia triticina Erikss. and 62% Uromycladium tepperianum) and lowest for carnations (4% P. triticina Erikss. and 5% U. tepperianum). Subsequently, the device was tested at several locations on the Central Coast of New South Wales, Australia, recently affected by a "myrtle rust" outbreak. Symptomatic and asymptomatic myrtle rust hosts, myrtle rust nonhosts, and inanimate objects (e.g., clothing and vehicles) were sampled in conjunction with the emergency response to the outbreak. A polymerase chain reaction (PCR) assay developed for P. psidii established the presence of myrtle rust, and visual inspections provided spore count estimations. All samples from symptomatic myrtle rust hosts produced positive PCR results and spore count estimations were generally much greater. Several samples from asymptomatic myrtle rust hosts, myrtle rust nonhosts, and inanimate objects also produced positive PCR results; however, there were discrepancies between PCR results and spore count estimations in some of these samples, all of which had <100 spores. This study highlights the utility of the device and analytical methodology, especially during the early stages of a disease outbreak when infection symptoms on plants and contamination on objects is not visible upon gross examination.

Abstract
INTRODUCTION A number of international guidelines have been developed to support primary care clinicians improve the quality of care for patients with chronic heart failure at the end of life. The objective of this study was to undertake a systematic evaluation of such guidelines in relation to end-of-life care. METHODS A systematic literature search of research databases and guideline clearing houses was undertaken. The selected guidelines were independently assessed by two researchers using the AGREE II quality criteria. A data-extraction framework was devised based on the holistic needs assessment tool of the Gold Standards Framework. The content of each guideline was then analysed using an approach similar to that used for thematic analysis. RESULTS A total of 19 guidelines were included. Those guidelines with lower overall AGREE II scores covered fewer domains on the holistic needs assessment. Across all guidelines the lowest scoring domain was applicability and stakeholder involvement. Qualitative assessment showed that some guidelines adopt an unwavering disease orientated approach to assessing patient need. Guidance around continuity of care, out of hours care and after care was particularly poor in several guidelines. There was considerable heterogeneity in the evidence presented even amongst those guidelines that achieved high AGREE II scores. CONCLUSION Combined quantitative and qualitative assessment demonstrates the importance of rigorous guideline development. Whilst the variation in evidence presented could be a result of methodological heterogeneity in the development of guidelines, it raises important questions about the processes by which evidence, information and knowledge become transformed into clinical guidelines.

Abstract
Abstract
Background: We previously described a Chloride Intracellular Channel-3 (CLIC3)-dependent recycling pathway which trafficked active integrins from late endosomes to the cell surface and which was required for the migratory and invasive behaviour of A2780 ovarian cancer cells in vitro. We also demonstrated that elevated expression of CLIC3 was associated with poor prognosis in pancreatic cancer. We therefore set out to investigate the role of CLIC3 in breast cancer.
Materials and Methods: CLIC3 expression was assessed by immunohistochemistry and the weighted histoscore method in a tissue microarray (TMA) consisting of triplicate cores from 141 patients diagnosed with invasive estrogen receptor (ER)-negative early breast carcinoma between 1995 and 1998. Full clinicopathological and follow-up data were available. Further data were obtained from publicly available gene expression datasets (Desmedt, GSE7390) and Oncomine™. Knockdown of CLIC3 in the ER-ve MDA-MB231 breast cancer cell line was achieved by nucleofection of 2 different siRNA sequences (Dharmacon). Inverse invasion assays measured invasion into a plug of matrigel supplemented with fibronectin over 72 hours whilst organotypic invasion assays measured invasion into a fibroblast-containing collagen matrix over 6 days.
Results: CLIC3 mRNA expression was significantly elevated in breast cancer in comparison to normal breast tissue in two independent data sets. High CLIC3 protein levels were associated with significantly shorter breast cancer specific survival (p = 0.026) in a TMA of 141 ER-ve patients. This finding was corroborated by the observation that high CLIC3 mRNA levels were associated with shorter overall survival in 198 patients in the Desmedt dataset (p = 0.038). Transient silencing of CLIC3 expression using two independent siRNA sequences had no effect on proliferation of MDA-MB231 cells but significantly reduced their invasiveness by 46% and 93% respectively in an inverse invasion assay and by 36% and 42% respectively in an organotypic invasion assay. CLIC3 was found to co-localise with Rab7 and LAMP1 in late endosomes/lysosomes in MDA-MB231 cells.
Conclusions: Our clinical and in vitro data indicate an important role for CLIC3 in the invasive and metastatic behaviour of some breast cancers. Further work to elucidate molecular mechanisms is underway and will be presented.

Abstract
AIM It is recognised that colorectal cancer may arise from different genomic instability pathways. There is evidence to suggest that colon and rectal cancers exhibit different clinicopathological features. We examined the relationship between tumour site, clinicopathological characteristics and cancer-specific survival in patients undergoing potentially curative resection for colorectal cancer. METHOD Four hundred and eleven patients who underwent surgery. Clinicopathological data including components of the Peterson index, Klintrup scores, haemoglobin and the modified Glasgow Prognostic Score (mGPS) were studied. RESULTS There were 134 (33%) right sided, 125 (30%) left sided and 152 (37%) rectal tumours. Emergency presentation (P < 0.001), anaemia (P < 0.001), higher mGPS (P < 0.001), advanced T stage (P < 0.001), poor differentiation (P < 0.001) and older age (P < 0.05) were more commonly observed in right sided cancer. The mean follow-up was 94 months (minimum 36 months) and 114 patients died of cancer. There was no difference between tumour site and survival (P = 0.427). On multivariate analysis older age (P = 0.015), lymph node ratio (P < 0.001), mGPS (P = 0.028), Peterson Index (P < 0.001) and Klintrup score (P = 0.008) were independently related to cancer-specific survival. Klintrup score was only associated with poor cancer-specific survival in rectal cancer (P = 0.009). CONCLUSION The study suggests that colorectal cancer is a group of heterogeneous tumours with different clinicopathological features. Despite this, there was no difference between tumour site and survival. The prognostic role of clinicopathological factors in tumours arising from different genomic instability pathways requires further study.

Abstract
BACKGROUND Cell line models suggest that activation of NFκB is associated with progression of prostate cancer. This pathway may be a therapeutic target if these observations translate to clinical specimens. METHODS Immunohistochemistry measured NFκBp65 (p65), NFκBp65 nuclear localisation signal (NLS), NFκBp65 phosphorylated at ser 276 (p65(ser276)), NFκBp65 phosphorylated at ser 536 (p65(ser536)), IκBα phosphorylated at ser 32/36 (pIκBα(ser32/36)) and MMP-9 protein expression in 61 matched hormone naive prostate cancer (HNPC) and castrate-resistant prostate cancer (CRPC) tumours. Animal and cell models were used to investigate the role of NFκB inhibition in prostate carcinogenesis. RESULTS In HNPC tumours, NLS expression significantly associated with a shorter time to disease recurrence and disease-specific death. In CRPC tumours p65, pIκBα(ser32/36) and MMP-9 expression significantly associated with shorter time to death from disease recurrence and shorter disease-specific death. MMP-9 and pIκBα(ser32/36) expression significantly associated with metastases at recurrence and were independent of Gleason sum and prostate-specific antigen at recurrence. Expression of phosphorylated Akt was associated with increased p65 activation in mouse models and inhibition of NFκB in LNCaP cells significantly reduced cellular proliferation and induced apoptosis. CONCLUSION These results provide further evidence that the NFκB pathway could be exploited as a target for CRPC.

Abstract
The electron and ion temperatures of the imploded core plasma are two of the most important metrics of inertial confinement fusion experiments. We have developed a technique for inferring electron temperatures from the contrast of x-ray images observed through a group of x-ray filters. Generally, the plasma electron temperature exhibits spatial and temporal variations, so time-averaged and time-resolved measurements are expected to yield somewhat different results. By analyzing the intensity of images observed with both a time-integrated detector (imaging plates) and a time-resolved detector (gated micro-channel plate), we found the electron temperature observed from x-ray images to be systematically higher than the ion temperature inferred from fusion neutron spectroscopy.
