    There is evidence that consumption of foods containing dietary fiber decreases the risk of colorectal cancer (CRC). Whole grains contain dietary fiber, as well as a range of micronutrients and bioactive compounds, but the association between the consumption of whole grains and the risk of CRC remains less studied. The aim of the present study was to investigate the association between whole-grain bread consumption and CRC incidence among Norwegian women, using data from a prospective cohort study (the Norwegian Women and Cancer Study). Dietary intake was estimated from the food-frequency questionnaires of 78,254 women in the cohort (median age: 55 years), and these women were then followed up for CRC incidence. During the 9 years of median follow-up, 795 women were diagnosed with CRC (316 proximal, 193 distal, 218 rectal). Associations between whole-grain bread consumption and the risk of CRC (including colorectal subsites) were investigated using Cox proportional hazards regression models. When compared to the low consumption group, the hazard ratio for CRC was 0.89 (95% confidence interval (CI): 0.72-1.09) for the high consumption group and 0.86 (95% CI: 0.72-1.02) for the medium consumption group in a multivariable model. Overall, no association between whole-grain bread consumption and CRC was found. PMID:26771634

    Background Smoking, dietary factors, and alcohol consumption are known life style factors contributing to gastrointestinal carcinogenesis. Genetic variations in carcinogen handling may affect cancer risk. The multidrug resistance 1(MDR1/ABCB1) gene encodes the transport protein P-glycoprotein (a phase III xenobiotic transporter). P-glycoprotein is present in the intestinal mucosal lining and restricts absorption of certain carcinogens, among these polycyclic aromatic hydrocarbons. Moreover, P-glycoprotein transports various endogenous substrates such as cytokines and chemokines involved in inflammation, and may thereby affect the risk of malignity. Hence, genetic variations that modify the function of P-glycoprotein may be associated with the risk of colorectal cancer (CRC). We have previously found an association between the MDR1 intron 3 G-rs3789243-A polymorphism and the risk of CRC in a Danish study population. The aim of this study was to investigate if this MDR1 polymorphism was associated with risk of colorectal adenoma (CA) and CRC in the Norwegian population. Methods Using a case-control design, the association between the MDR1 intron 3 G-rs3789243-A polymorphism and the risk of colorectal carcinomas and adenomas in the Norwegian population was assessed in 167 carcinomas, 990 adenomas, and 400 controls. Genotypes were determined by allelic discrimination. Odds ratio (OR) and 95 confidence interval (95% CI) were estimated by binary logistic regression. Results No association was found between the MDR1 polymorphism (G-rs3789243-A) and colorectal adenomas or cancer. Carriers of the variant allele of MDR1 intron 3 had odds ratios (95% CI) of 0.97 (0.72–1.29) for developing adenomas, and 0.70 (0.41–1.21) for colorectal cancer, respectively, compared to homozygous wild type carriers. Conclusion The MDR1 intron 3 (G-rs3789243-A) polymorphism was not associated with a risk of colorectal adenomas or carcinomas in the present Norwegian study group. Thus, this

    Both individual patient treatment and cancer registries depend on adequate histopathology reports. To ensure the quality of these reports, professional organizations have published guidelines on minimum data sets for various cancer types. Norway has a population of 4.6 million, and all individuals have a unique identification number. As required by law, relevant information on cancer is submitted to the Cancer Registry of Norway. A closed, national health data network has been established facilitating electronic transferal between various institutions. The Cancer Registry and the Norwegian Society for Pathology have jointly established a nationwide project to (i) develop standardized templates in database format for histopathology reports on cancer resection specimens and (ii) develop an Extensible Markup Language (XML) standard to facilitate future electronic transfer of cancer reports from hospitals to the Cancer Registry. A minimum data set template for reporting colorectal carcinoma resection specimens and the Extensible Markup Language standard have been established. The template is based on international guidelines and classification systems. For most key parameters, pull-down menus with predefined alternatives have been constructed. The template is fully integrated into software being used by all pathology laboratories in Norway. Since the introduction of the template in April 2005, the template had been used for reporting 430 (93%) of 462 colorectal resections at 2 pilot laboratories (Akershus University Hospital [Lørenskog, Norway] and Stavanger, University Hospital [Stavanger, Norway]), demonstrating that high and consistent quality can be ascertained. Pathologists have found the template both time saving and user friendly. The template is now gradually implemented nationwide. PMID:18187180

  10. Norwegian mastitis control programme.

    2009-01-01

    This paper describes the methods and results of the Norwegian Mastitis Control Program implemented in 1982. The program has formed an integral part of the Norwegian Cattle Health Services (NCHS) since 1995. The NCHS also have specific programs for milk fever, ketosis, reproduction and calf diseases. The goal of the program is to improve udder health by keeping the bulk milk somatic cell count (BMSCC) low, to reduce the use of antibiotics, to keep the cost of mastitis low at herd level and improve the consumers' attitude to milk products. In 1996, a decision was made to reduce the use of antibiotics in all animal production enterprises in Norway by 25% within five years. Relevant data has been collected through the Norwegian Cattle Herd Recording System (NCHRS); including health records since 1975 and somatic cell count (SCC) data since 1980. These data have been integrated within the NCHRS. Since 2000, mastitis laboratory data have also been included in the NCHRS. Data on clinical disease, SCC and mastitis bacteriology have been presented to farmers and advisors in monthly health periodicals since 1996, and on the internet since 2005. In 1996, Norwegian recommendations on the treatment of mastitis were implemented. Optimal milking protocols and milking machine function have been emphasised and less emphasis has been placed on dry cow therapy. A selective dry cow therapy program (SDCTP) was implemented in 2006, and is still being implemented in new areas. Research demonstrates that the rate of clinical mastitis could be reduced by 15% after implementing SDCTP. The results so far show a 60% reduction in the clinical treatment of mastitis between 1994 and 2007, a reduction in BMSCC from 250,000 cells/ml to 114,000 cells/ml, and a total reduction in the mastitis cost from 0.23 NOK to 0.13 NOK per litre of milk delivered to the processors, corresponding to a fall from 9.2% to 1.7% of the milk price, respectively. This reduction is attributed to changes in attitude and

    Archival material has revealed milestones and new details in the history of the Norwegian Naval Observatories. We have identified several of the instrument types used at different epochs. Observational results have been extracted from handwritten sources and an extensive literature search. These allow determination of an approximate location of the first naval observatory building (1842) at Fredriksvern. No physical remains exist today. A second observatory was established in 1854 at the new main naval base at Horten. Its location is evident on military maps and photographs. We describe its development until the Naval Observatory buildings, including archives and instruments, were completely demolished during an allied air bomb raid on 23 February 1945. The first director, C.T.H. Geelmuyden, maintained scientific standards at the the Observatory between 1842 and 1870, and collaborated with university astronomers to investigate, develop, and employ time-transfer by telegraphy. Their purpose was accurate longitude determination between observatories in Norway and abroad. The Naval Observatory issued telegraphic time signals twice weekly to a national network of sites, and as such served as the first national time-service in Norway. Later the Naval Observatory focused on the particular needs of the Navy and developed into an internal navigational service.

    We describe tularaemia in a Norwegian dog caused by Francisella tularensis subspecies holarctica. A Hamilton Hound and his owner developed tulaeremia after hunting an infected mountain hare (Lepus timidus). The dog showed signs of lethargy, anorexia and fever during a period two to four days after hunting and thereafter fully recovered. Its antibody titers increased 32-fold from one to three weeks post exposure. Thereafter, the titer declined and leveled off at moderate positive values up to one year after exposure (end of study). This is believed to be the first case report of clinical F. tularensis subspecies holarctica infection in a European dog. In 2011, enormous numbers of Norway lemmings (Lemmus lemmus) occurred in Finnmark, the northernmost county of Norway and many dogs caught and swallowed lemmings. Some of these dogs developed non-specific signs of disease and the owners consulted a veterinary surgeon, who suspected tularaemia. In order to investigate this hypothesis, serum samples from 33 dogs were examined for antibodies to F. tularensis. The dogs were allocated into three groups: Dogs from Finnmark that became sick (Group 1) or remained healthy following contact with lemmings (Group 2), and healthy control dogs from Oslo without known contact with lemmings (Group 3). All the serum samples were analyzed with a tube agglutination assay. Among dogs exposed to lemmings, 10/11 and 3/12 were antibody positive in Group 1 and Group 2, respectively, whereas none of the control dogs (n=10) were positive for antibodies against F. tularensis. These results strongly indicate that the non-specific disease seen in the dogs in Finnmark was linked to F. tularensis infection acquired through contact with lemmings. PMID:25150161

    1982-01-01

    The mean bodyweight, in kilograms, and mean weightlifting result, in points, for the ten best weightlifters at the annual Norwegian championships 1962-82 have been studied. During the 21 years, the mean bodyweight for these ten increased by 18 kg, probably due to the effect of androgens. The weightlifting results improved rapidly from 1968 onwards, probably reflecting an increasingly widespread use of anabolic steroids by Norwegian weightlifters. In 1977 doping tests were introduced, and from then on, rate of improvement has increased much more slowly. The annual sale of anabolic steroids 1963-81 and testosterone 1974-81, in Norway have been recorded. The sale of anabolic steroids increased irregularly until 1974-75, and has since shown a 42% decrease. The sale of testosterone 1974-81 showed a slight reduction, thus giving no support to the suggestion that doping tests for anabolic steroids would lead to a transfer to testosterone abuse.

    New assays on two important Norwegian North Sea crude oils, Statfjord and Gullfaks, are presented. Both are high-quality, low-sulfur crudes that will yield a full range of good-quality products. All assay data came from industry-standard test procedures. The Statfjord field is the largest in the North Sea. Production started in 1979. Statfjord is a typical North Sea crude, produced from three separate platforms and three separate loading buoys with interconnecting lines. Current production is about 700,000 b/d. Gullfaks is produced from a large field in Block 34/10 of the Norwegian sector of the North Sea production area. Gullfaks crude oil is more biodegraded than other crudes from the region. Biodegradation has removed most of the waxy normal paraffins, resulting in a heavier, more naphthenic and aromatic crude.

    The Norwegian Offshore Stratigraphic Lexicon (NORLEX) provides a relational stratigraphic database for the North Sea, Norwegian Sea, Barents Sea and Svalbard. Both regional lithostratigraphy and biostratigraphy are being substantially updated, following guidelines laid out in the International Stratigraphic Guide. The main body of information developed is available as a petroleum consortium (oracle-style) database, and the new lithostratigraphic definitions as a public domain (paper) document. NORLEX is presented as a browsing website via the internet at http://www.nhm.uio.no/norlex. Seismic cross-sections, core photographs, well logs, field outcrops, microfossil occurrences and other vital attributes are relationally cross-linked. In addition, there are menus for instantly finding updated formation and member tops or microfossil events in all wells, plus a map contouring routine for unit thicknesses and depths. Several new initiatives will expand data and user coverage: 1. Overhaul of Mesozoic stratigraphy, especially Triassic and Cretaceous, in the Barents Sea. 2. Coverage of East Greenland 3. Linkage to UK and Belgium and The Netherlands surface and subsurface stratigraphy 4. Creation of a Sequence Stratigraphic Framework for specific regions. 5. A national microfossil atlas to support zonations 6. Tight linkage to the basin datapacks in TimeScaleCreator Pro, as developed for Australia, New Zealand, Brasil, Gulf of Mexico, Canada and Russia. NORLEX may thus evolve to become STRATLEX, covering many basin regions.

    The Norwegian Ocean Observatory Network (NOON) is led by the University of Tromsø and collaborates with the Universities of Oslo and Bergen, UniResearch, Institute of Marine Research, Christian Michelsen Research and SINTEF. It is supported by the Research Council of Norway and oil and gas (O&G) industries like Statoil to develop science, technology and new educational programs. Main topics relate to ocean climate and environment as well as marine resources offshore Norway from the northern North Atlantic to the Arctic Ocean. NOON's vision is to bring Norway to the international forefront in using cable based ocean observatory technology for marine science and management, by establishing an infrastructure that enables real-time and long term monitoring of processes and interactions between hydrosphere, geosphere and biosphere. This activity is in concert with the EU funded European Strategy Forum on Research Infrastructures (ESFRI) roadmap and European Multidisciplinary Seafloor Observation (EMSO) project to attract international leading research developments. NOON envisions developing towards a European Research Infrastructure Consortium (ERIC). Beside, the research community in Norway already possesses a considerable marine infrastructure that can expand towards an international focus for real-time multidisciplinary observations in times of rapid climate change. PIC The presently established cable-based fjord observatory, followed by the establishment of a cable-based ocean observatory network towards the Arctic from an O&G installation, will provide invaluable knowledge and experience necessary to make a successful larger cable-based observatory network at the Norwegian and Arctic margin (figure 1). Access to large quantities of real-time observation from the deep sea, including high definition video, could be used to provide the public and future recruits to science a fascinating insight into an almost unexplored part of the Earth beyond the Arctic Circle

    Colorectal cancer has become one of the most prevalent malignant diseases for both men and women. Patients with inflammatory bowel diseases or certain inherited cancer syndromes are at high risk of developing colorectal cancer and have naturally the highest need for cancer prevention. In familial adenomatous polyposis (FAP) and Lynch syndrome, most of the underlying germline mutations can be detected by DNA sequencing, and medical counselling of affected individuals involves both surveillance tests and chemopreventive measures. However, as the mechanisms leading to colorectal cancer differ in these high-risk groups, the molecular action of chemopreventive drugs needs to be adjusted to the certain pathway of carcinogenesis. In the last decades, a number of drugs have been tested, including sulindac, aspirin, celecoxib, and mesalazine, but some of them are still controversially discussed. This review summarizes the advances and current standards of colorectal cancer prevention in patients with inflammatory bowel disease, FAP and Lynch syndrome. PMID:25531498

    Colorectal cancer is a important public health problem: there are nearly one million new cases of colorectal cancer diagnosed world-wide each year and half a million deaths. Recent reports show that, in the US, it was the most frequent form of cancer among persons aged 75 years and older. Given that the majority of cancers occur in elder people and with the ageing of the population in mind, this observation gives further impetus to investigating prevention and treatment strategies among this subgroup of the population. Screening research, recommendations and implementation is an obvious priority. While there are many questions to be resolved, it is apparent that many facets of colorectal cancer are becoming increasingly understood and prospects for prevention are becoming apparent. Achieving colorectal cancer control is the immediate challenge. PMID:12421722

It is estimated that as many as 60% of colorectal cancer deaths could be prevented if all men and women aged 50 years or older were screened routinely. In 2000, Katie Couric's televised colonoscopy led to a 20% increase in screening colonoscopies across America, a stunning rise called the "Katie Couric Effect". This event demonstrated how celebrity endorsement affects health behavior. Currently, discussion is ongoing about the optimal strategy for CRC screening, particularly the costs of screening colonoscopy. The current CRC screening guidelines are summarized in Table 2. Debates over the optimum CRC screening test continue in the face of evidence that 22 million Americans aged 50 to 75 years are not screened for CRC by any modality and 25,000 of those lives may have been saved if they had been screened for CRC. It is clear that improving screening rates and reducing disparities in underscreened communities and population subgroups could further reduce colorectal cancer morbidity and mortality. National Institutes of Health consensus identified the following priority areas to enhance the use and quality of colorectal cancer screening: Eliminate financial barriers to colorectal cancer screening and appropriate follow-up of positive results of colorectal cancer screening. Develop systems to ensure the high quality of colorectal cancer screening programs. Conduct studies to determine the comparative effectiveness of the various colorectal cancer screening methods in usual practice settings. Encouraging population adherence to screening tests and allowing patients to select the tests they prefer may do more good (as long as they choose something) than whatever procedure is chosen by the medical profession as the preferred test.

    The incidence of colorectal cancer increased in France until the 2000s' then decreased. Time trends in incidence for this cancer varied according to its sublocation along the gut. Incidence increased for right and left colon cancers, whereas it remained stable for sigmoid cancers in males and decreased in females. Incidence decreased over time for rectal cancers. The proportion of colorectal cancer in the overall French cancer prevalence is 12%. In 2008, 121,000 patients had a colorectal cancer diagnosed in the 5 previous years. The cumulative risk of colorectal cancer increased from 3.9% for males born around 1900 to 4.9% for those born around 1930 and then slightly decreased, being 4.5% among those born around 1950. It remained at the same level for females and was 2.9% for those born around 1950. The prognosis of colorectal cancer improved over time. Net 5-year survival increased in males from 53% for cancers diagnosed between 1989 and 1991 to 58% for those diagnosed between 2001 and 2004. The highest improvement of 10 year survival rates concerned left colon and rectosigmoid junction (+19% in a decade). The progressive set up of national colorectal screening since the early 2000's and the introduction of recent immunological tests in 2015 should decrease the mortality for this cancer and, at term, should decrease its incidence too.

    This paper reports on the Norwegian Sea, lying between the Norwegian North Sea and the western flank of the Barents Sea, which is set to become Norway's second oil and gas producing province. Oil is scheduled to start to flow near the end of next year when AS Norske Shell places on production 428 million bbl Draugen field in Block 6407/9, about 60 miles off the coast of mid-Norway in the frontier sea area known as Haltenbanken. Two years later, in 1995, Norske Conoco AS will add to the 95,000 b/d from Draugen when it commissions the world's first concrete hull tension leg platform (TLP) in Heidrun field. The TLP is expected to produce 200,000 b/d of oil and move associated gas by pipeline to the Norwegian mainland to feed a worldscale methanol plant planned for construction at Tjeldbergodden. The Norwegian government also has been asked to approve a gas pipeline link between Haltenbanken and the gas export infrastructure in the North Sea.

    Scabies is a contagious condition that is transmitted through direct contact with an infected person and has been frequently associated with institutional and healthcare-facility outbreaks. The subtype Norwegian crusted scabies can masquerade as other dermatologic diseases owing to the heavy plaque formation. Successful treatment has been documented in published reports, including oral ivermectin and topical permethrin. Few case studies documenting the treatment of Norwegian crusted scabies have reported the use of surgical debridement as an aid to topical and/or oral treatment when severe plaque formation has been noted. A nursing home patient was admitted to the hospital for severe plaque formation of both feet. A superficial biopsy was negative for both fungus and scabies because of the severity of the plaque formation on both feet. The patient underwent a surgical, diagnostic biopsy of both feet, leading to the diagnosis of Norwegian crusted scabies. A second surgical debridement was then performed to remove the extensive plaque formation and aid the oral ivermectin and topical permethrin treatment. The patient subsequently made a full recovery and was discharged back to the nursing home. At 2 and 6 months after treatment, the patient remained free of scabies infestation, and the surgical wound had healed uneventfully. The present case presentation has demonstrated that surgical debridement can be complementary to the standard topical and oral medications in the treatment of those with Norwegian crusted scabies infestation.

    This survey focuses on the subject of euthanasia. A questionnaire was sent to 90 doctors working in pain clinics in Norwegian hospitals. 60 doctors (67%) returned the questionnaire. Only 18 doctors (30%) had ever received a request for euthanasia. The patients who requested euthanasia suffered from refractory pain, depression, fear of pain and fear of becoming helpless. 67% of the doctors were satisfied with the present Norwegian law, while 13% favoured a liberalization of the law. Only 5% were willing to comply with the patient's request for euthanasia under today's law. One third of the doctors would leave the decision to an officially appointed "board" if euthanasia were to become legalized. A majority wanted a doctor to commit the actual procedure, but there were also suggestions that a lawyer or other lay person should carry out the act of euthanasia. Our conclusion is that the closer the patient-doctor relationship is, the more opposed the doctor is to euthanasia. PMID:9816949

    The world's largest ship-shaped floating production facility will mine hydrocarbons trapped below 1,246-ft, harsh Norwegian waters at the Norne field. An innovative development philosophy involving functional specifications and life-of-field bench marking will ensure costs and lead time to first oil are minimized. The Block 6608/10 Norne field is the largest discovery on the Norwegian continental shelf in more than a decade. The field extends for 6.2 miles, is 1.24 miles wide and sits 124 miles west of the mid-Norway coast in 1,246-ft waters. Well No. 6608/10-2 first penetrated the Norne reservoir in December 1991. Appraisal well 6608/10-3 was drilled in 1993 and proved the field's northerly extension. Based on results from those two wells, a development project began last year. To improve project economics and company performance, a clear objective was established to reduce investment costs by 25%--30% compared to the current established level in Norway. The Norne organization is working on a Plan for Development and Operation to be submitted to Norwegian authorities later this year so that final approval can be obtained in early 1995.

    On July 22, 2011, there were two murderous attacks in Norway. Both assaults - the bombing of governmental buildings in Oslo City center and the lethal shooting down of young members of the Labour Party on an island - were planned and accomplished by a lone perpetrator. These episodes give rise to several interesting questions. What happened really, and how could it happen? Was the perpetrator sane or insane? What was the ideological background for the attacks? It is unnecessary to discuss in any detail whether or not these acts should be categorized as terrorism. However, there is good reason to consider what these terror attacks imply for Norwegian society at large. What significance did the attacks have for Norwegian democracy, and did they have any impact on the 2013 parliamentary elections? What will be the future for the offender, both in the short term and in years to come? What will happen to the Norwegian insanity defense? These questions are addressed in this article.

  17. Management of Colorectal Trauma

    2011-01-01

    Although the treatment strategy for colorectal trauma has advanced during the last part of the twentieth century and the result has improved, compared to other injuries, problems, such as high septic complication rates and mortality rates, still exist, so standard management for colorectal trauma is still a controversial issue. For that reason, we designed this article to address current recommendations for management of colorectal injuries based on a review of literature. According to the reviewed data, although sufficient evidence exists for primary repair being the treatment of choice in most cases of nondestructive colon injuries, many surgeons are still concerned about anastomotic leakage or failure, and prefer to perform a diverting colostomy. Recently, some reports have shown that primary repair or resection and anastomosis, is better than a diverting colostomy even in cases of destructive colon injuries, but it has not fully established as the standard treatment. The same guideline as that for colonic injury is applied in cases of intraperitoneal rectal injuries, and, diversion, primary repair, and presacral drainage are regarded as the standards for the management of extraperitoneal rectal injuries. However, some reports state that primary repair without a diverting colostomy has benefit in the treatment of extraperitoneal rectal injury, and presacral drainage is still controversial. In conclusion, ideally an individual management strategy would be developed for each patient suffering from colorectal injury. To do this, an evidence-based treatment plan should be carefully developed. PMID:21980586

    Diet plays an important role in the pathogenesis of colorectal cancer. Current prospective cohort studies and metaanalysis enable a reevaluation of how food or nutrients such as fiber and fat influence cancer risk. Based on the evidence criteria of the WHO/FAD, risk reduction by a high intake of fruit is assessed as possible, while a lowered risk by a high vegetable intake is probable. Especially raw vegetables and fruits seem to exert anticancer properties. The evidence of a risk reducing effect of whole grain relating to colorectal cancer is assessed as probable whereas the evidence of an increased risk by high consumption of refined white flour products and sweets is (still) insufficient despite some evidences. There is a probable risk reducing effect of milk and dairy products. e available data on eggs and red meat indicate a possible risk increasing influence. Stronger clues for a risk increasing effect have been shown for meat products leading to an evidence assessed as probable. Owing to varied interpretations of the data on fiber, the evidence of a risk reducing effect relating to colorectal cancer is assessed as possible or insufficient. The available data on alcohol consumption indicate a possible risk increasing effect. In contrast to former evaluations, diets rich in fat seem to increase colorectal cancer risk only indirectly as part of a hypercaloric diet by advancing the obesity risk. Thus, the evidence of obesity, especially visceral obesity, as a risk of colorectal cancer is judged as convincing today. Prospective cohort studies suggest that people who get higher than average amounts of folic acid from multivitamin supplements have lower risks of colorectal cancer. The evidence for a risk reducing effect of calcium, selenium, vitamin D and vitamin E on colorectal cancer is insufficient. As primary prevention, a diet rich in vegetables, fruits, whole grain products, and legumes added by low-fat dairy products, fish, and poultry can be recommended. In

    This study examines the accuracy of colorectal cancer radioimmunodetection. Twenty-seven patients with a history of histologically-confirmed colonic or rectal carcinoma received a high-titer, purified goat anti-CEA IgG labelled with /sup 131/I at a total dose of at least 1.0 ..mu..Ci. Various body views were scanned at 24 and 48 hours after administration of the radioantibody. Three additional cases were evaluated; one had a villous adenoma in the rectum and received the /sup 131/I-labeled anti-CEA IgG, while two colonic carcinoma patients received normal goat IgG labelled with /sup 131/I. All of the 7 cases with primary colorectal cancer showed true-positive tumor localization, while 20 of 25 sites of metastatic colorectal cancer detected by immune scintigraphy were corroborated by other detection measures. The sensitivity of the radioimmunodetection of colorectal cancers (primary and metastatic) was found to be 90% (true-positive rate), the putative specificity (true-negative rate) was 94%, and the apparent overall accuracy of the technique was 93%. Neither the case of a villous adenoma receiving the anti-CEA IgG nor the two cases of colonic cancer receiving normal goat IgG showed tumor radiolocalization. Very high circulating CEA titers did not appear to hinder successful tumor radiolocalization. These findings suggest that in colorectal cancers the method of CEA radioimmunodetection may be of value in preoperatively determining the location and extent of disease, in assessing possible recurrence or spread postoperatively, and in localizing the source of CEA production in patients with rising or elevated CEA titers. An ancilliary benefit could be a more tumor-specific detection test for confirming the findings of other, more conventional diagnostic measures.

    Previous studies have documented significant international variations in colorectal cancer rates. However, these studies were limited because they were based on old data or examined only incidence or mortality data. In this article, the colorectal cancer burden and patterns worldwide are described using the most recently updated cancer incidence and mortality data available from the International Agency for Research on Cancer (IARC). The authors provide 5-year (1998-2002), age-standardized colorectal cancer incidence rates for select cancer registries in IARC's Cancer Incidence in Five Continents, and trends in age-standardized death rates by single calendar year for select countries in the World Health Organization mortality database. In addition, available information regarding worldwide colorectal cancer screening initiatives are presented. The highest colorectal cancer incidence rates in 1998-2002 were observed in registries from North America, Oceania, and Europe, including Eastern European countries. These high rates are most likely the result of increases in risk factors associated with "Westernization," such as obesity and physical inactivity. In contrast, the lowest colorectal cancer incidence rates were observed from registries in Asia, Africa, and South America. Colorectal cancer mortality rates have declined in many longstanding as well as newly economically developed countries; however, they continue to increase in some low-resource countries of South America and Eastern Europe. Various screening options for colorectal cancer are available and further international consideration of targeted screening programs and/or recommendations could help alleviate the burden of colorectal cancer worldwide.

    Colorectal cancer is the paradigm of tumoral growth that is susceptible to preventive measures, especially screening. Various screening strategies with demonstrated efficacy and efficiency are currently available, notable examples being the fecal occult blood test and endoscopic tests. In addition, new modalities have appeared in the last few years that could become viable alternatives in the near future. The present article reviews the most important presentations on colorectal screening at the annual congress of the American Gastroenterological Association held in Orlando in May 2013, with special emphasis on the medium- and long-term results of strategies using the fecal occult blood test and flexible sigmoidoscopy, as well as initial experiences with the use of new biomarkers.

    Colorectal anastomotic leak remains one of the most feared post-operative complications, particularly after anterior resection of the rectum with, the shift from abdomino-peritoneal resections to total mesorectal excision and primary anastomosis. The literature fails to demonstrate superiority of stapled over hand-sewn techniques in colorectal anastomosis, regardless of the level of anastomosis, although a high stricture rate was noted in the former technique. Thus, improvements in safety aspects of anastomosis and alternatives to hand-sewn and stapled techniques are being sought. Here, we review alternative anastomotic techniques used to fashion bowel anastomosis. Compression anastomosis using compression anastomotic clips, endoluminal compression anastomotic rings, AKA-2, biofragmental anastomotic rings, or Magnamosis all involve the concept of creating a sutureless end-to-end anastomosis by compressing two bowel ends together, leading to a simultaneous necrosis and healing process that joins the two lumens. Staple line reinforcement is a new approach that reduce the drawbacks of staplers used in colorectal practice, i.e. leakage, bleeding, misfiring, and inadequate tissue approximation. Various non-absorbable, semi or fully absorbable materials are now available. Two other techniques can provide alternative anastomotic support to the suture line: a colorectal drain and a polyester stent, which can be utilized in ultra-low rectal excision and can negate the formation of a defunctioning stoma. Doxycycline coated sutures have been used to overcome the post-operative weakness in anastomosis secondary to rapid matrix degradation mediated by matrix metalloproteinase. Another novel technique, the electric welding system, showed promising results in construction of a safe, neat, smooth sutureless bowel anastomosis. Various anastomotic techniques have been shown to be comparable to the standard techniques of suturing and stapling. However, most of these alternatives need

    This technical note describes a method of biceps tenodesis called the Modified Norwegian Method that is an all-arthroscopic, intra-articular, bony biceps tenodesis that uses a suture shuttle passer through an anterosuperolateral portal. It allows for easy passage of suture through the long head of the biceps tendon while one is viewing through the posterior portal. We believe this method to be a very reasonable and simple method of biceps tenodesis that has complication rates similar to those described for subpectoral and other methods of fixation.

    Colorectal cancer is a serious health problem, a challenge for research, and a model for studying the molecular mechanisms involved in its development. According to its incidence, this pathology manifests itself in three forms: family, hereditary, and most commonly sporadic, apparently not associated with any hereditary or familial factor. For the types having inheritance patterns and a family predisposition, the tumours develop through defined stages ranging from adenomatous lesions to the manifestation of a malignant tumour. It has been established that environmental and hereditary factors contribute to the development of colorectal cancer, as indicated by the accumulation of mutations in oncogenes, genes which suppress and repair DNA, signaling the existence of various pathways through which the appearance of tumours may occur. In the case of the suppressive and mutating tracks, these are characterised by genetic disorders related to the phenotypical changes of the morphological progression sequence in the adenoma/carcinoma. Moreover, alternate pathways through mutation in BRAF and KRAS genes are associated with the progression of polyps to cancer. This review surveys the research done at the cellular and molecular level aimed at finding specific alternative therapeutic targets for fighting colorectal cancer. PMID:25932044

Recent findings Colorectal imaging advances with magnetic resonance (MR), CT colonography (CTC), and positron emission tomography (PET) over the past year or so have been substantial. Progress in MR imaging for rectal cancer was most notable in terms of assessment of response to neoadjuvant therapy. Continued maturation and clinical validation of CTC was observed for the evaluation of advanced neoplasia, among other areas. Multimodality approaches to colorectal imaging that incorporate functional PET data have also made impressive strides forward. Summary Recent advances in cross-sectional and functional radiologic imaging of the colorectum will positively impact the clinical capabilities for noninvasive evaluation of colorectal neoplasia PMID:25394232

    Department of Medicine, Queen Elizabeth Hospital, Birmingham B15 2TH, UK P BOYLE Colorectal cancer is the fourth commonest form of cancer in men with 678 000 estimated new cases per year worldwide, representing 8.9% of all new cancers. The disease is most frequent in Occidental countries and particularly so in North America, Australia, New Zealand, and parts of Europe. Prospects for colorectal cancer control are bright and a number of possible approaches could prove fruitful. Among these, pharmaceutical measures seem to be valid and logical approaches to the prevention of colorectal cancer and diminishing its impact. Such approaches could concentrate in primary prevention in at-risk subjects or be applied in altering the course of precursor or established disease. Treatments used must fulfil basic requirements of biological plausibility and safety in continued use in large numbers of subjects. Those available include vitamins and minerals, and other drugs with potential as antioxidants, immune modulators or promoters of cell differentiation or apoptosis. Of the various regimens suggested, vitamin A supplementation may even predispose to adverse outcomes, and antioxidant vitamins in general have no coherent body of evidence to support their use. N-acetylcysteine and ursodeoxycholic acid have promising characteristics but there are as yet no clinical data to support the use of the former in gut epithelial cancer, and formal dose ranging studies must be carried out before the latter is submitted to large scale trial. Folate shows promising characteristics but non-steroidal anti-inflammatory drugs and vitamin D seem the most promising agents. Both seem to reduce the incidence of disease, and to reduce growth rates and/or induce differentiation or apoptosis in gut epithelial cancer cells. Both are also well understood pharmacologically. They may be preferred to newer selective compounds in the same class until these newer compounds are confirmed as safe for widespread

    This study was undertaken by the Norwegian Petroleum Directorate and SINTEF to identify hydrate problems occurring in pipelines on the Norwegian continental shelf. A brief review of hydrate dissociation theory is given. Three major techniques for hydrate removal are discussed, as well as hazards related to hydrate plug removal. Questionnaire answers from 15 companies operating in Norwegian waters show three specific occurrences of hydrate plugs in the North Sea. Problems from other geographical areas are also discussed. Hydrate problems are reported for a wide variety of pipe lengths, diameters, profiles, insulations characteristics and fluids. Most problems occur during normal operation.

    Identifying individuals with a genetic predisposition to developing familial colorectal cancer (CRC) is crucial to the management of the affected individual and their family. In order to do so, the physician requires an understanding of the different gene mutations and clinical manifestations of familial CRC. This review summarises the genetics, clinical manifestations and management of the known familial CRC syndromes, specifically Lynch syndrome, familial adenomatous polyposis, MUTYH-associated neoplasia, juvenile polyposis syndrome and Peutz-Jeghers syndrome. An individual suspected of having a familial CRC with an underlying genetic predisposition should be referred to a familial cancer centre to enable pre-test counselling and appropriate follow up.

    Colorectal cancer has been strongly associated with a Western lifestyle. In the past several decades, much has been learned about the dietary, lifestyle, and medication risk factors for this malignancy. Although there is controversy about the role of specific nutritional factors, consideration of the dietary pattern as a whole appears useful for formulating recommendations. For example, several studies have shown that high intake of red and processed meats, highly refined grains and starches, and sugars is related to increased risk of colorectal cancer. Replacing these factors with poultry, fish, and plant sources as the primary source of protein; unsaturated fats as the primary source of fat; and unrefined grains, legumes and fruits as the primary source of carbohydrates is likely to lower risk of colorectal cancer. Although a role for supplements, including vitamin D, folate, and vitamin B6, remains uncertain, calcium supplementation is likely to be at least modestly beneficial. With respect to lifestyle, compelling evidence indicates that avoidance of smoking and heavy alcohol use, prevention of weight gain, and the maintenance of a reasonable level of physical activity are associated with markedly lower risks of colorectal cancer. Medications such as aspirin and non-steroidal anti-inflammatory drugs and post-menopausal hormones for women are associated with significant reductions in colorectal cancer risk, though their utility is affected by associated risks. Taken together, modifications in diet and lifestyle should substantially reduce the risk of colorectal cancer and could complement screening in reducing colorectal cancer incidence. PMID:20420944

    The UK NHS quality proposals require all NHS organisations to develop an "integrated approach " to quality. In other countries, health care organisations are also working to ensure that the many different quality methods and systems used in health organisations do not duplicate or conflict with each other. The question this paper addresses is "what would an integrated approach to quality look like and how might managers and clinicians develop such an approach in their organisation?" The findings from the Norwegian total quality management experiment in six hospitals were that TQM could not be applied in its pure form in public health care services to ensure integration. The paper draws on this research to describe these hospitals' approach to integrate the different projects and systems which were stimulated by their initial quality programmes. The paper describes the "integrated quality development" approach which characterised these programmes. PMID:11547821

    An informed consumer can compensate for several potential food safety violations or contaminations that may occur earlier in the food production chain. However, a consumer can also destroy the work of others in the chain by poor food handling practices, e.g., by storing chilled ready-to-eat foods at abusive temperatures. To target risk-reducing strategies, consumer groups with high-risk behavior should be identified. The aim of this study was to identify demographic characteristics associated with high-risk food handling practices among Norwegian consumers. More than 2,000 randomly selected Norwegian consumers were surveyed, and the results were analyzed with a risk-based grading system, awarding demerit points for self-reported food safety violations. The violations were categorized into groups, and an ordinary multiple linear regression analysis was run on the summarized demerit score for each group and for the entire survey group as a whole. Young and elderly men were identified as the least informed consumer groups with the most unsafe practices regarding food safety. Single persons reported poorer practices than those in a relationship. People with higher education reported poorer practices than those with lower or no education, and those living in the capital of Norway (Oslo) reported following more unsafe food practices than people living elsewhere in Norway. Men reported poorer food safety practices than women in all categories with two exceptions: parboiling raw vegetables before consumption and knowledge of refrigerator temperature. These findings suggest that risk-reducing measures should target men, and a strategy is needed to change their behavior and attitudes. PMID:24215699

    Oil and gas exploration in the northern North Sea and the southern Norwegian shelf has mainy been concentrated on Jurassic and younger reservoirs with Late Jurassic black shale source rocks. New onshore investigations in Jameson Land, central East Greenland, suggest that the Permian of the Norwegian-Greenland Sea margins contains relatively thick sequences of potential oil source rocks interbedded with carbonate reefs. The East Greenland, Upper Permian marine basin is exposed over a length of 400 km (250 mi) from Jameson Land in the south to Wollaston Forland in the north, parallel with the continental margin. The Upper Permian black shale is relatively thick, widely distributed, has a high organic carbon content, and a favorable kerogen type. Consequently, the possibilities for a Permian play in the northern part of the Norwegian shelf and along parts of the Norwegian-Greenland Sea margins are worth evaluating.

    Background The risk of sporadic colorectal cancer (CRC) is mainly associated with lifestyle factors, particularly dietary factors. Diets high in red meat and fat and low in fruit and vegetables are associated with an increased risk of CRC. The dietary effects may be modulated by genetic polymorphisms in biotransformation genes. In this study we aimed to evaluate the role of dietary factors in combination with genetic factors in the different stages of colorectal carcinogenesis in a Norwegian population. Methods We used a case-control study design (234 carcinomas, 229 high-risk adenomas, 762 low-risk adenomas and 400 controls) to test the association between dietary factors (meat versus fruit, berries and vegetables) genetic polymorphisms in biotransformation genes (GSTM1, GSTT1, GSTP1 Ile105Val, EPHX1 Tyr113His and EPHX1 His139Arg), and risk of colorectal carcinomas and adenomas. Odds ratio (OR) and 95% confidence interval (95% CI) were estimated by binary logistic regression. Results A higher ratio of total meat to total fruit, berry and vegetable intake was positively associated with both high and low-risk adenomas, with approximately twice the higher risk in the 2nd quartile compared to the lowest quartile. For the high-risk adenomas this positive association was more obvious for the common allele (Tyr allele) of the EPHX1 codon 113 polymorphism. An association was also observed for the EPHX1 codon 113 polymorphism in the low-risk adenomas, although not as obvious. Conclusion Although, the majority of the comparison groups are not significant, our results suggest an increased risk of colorectal adenomas in individuals for some of the higher ratios of total meat to total fruit, berry and vegetable intake. In addition the study supports the notion that the biotransformation enzymes GSTM1, GSTP1 and EPHX1 may modify the effect of dietary factors on the risk of developing colorectal carcinoma and adenoma.

    Approximately 90% of colorectal cancer cases are sporadic without family history or genetic predisposition, while in less than 10% a causative genetic event has been identified. Historically, colorectal cancer classification was only based on clinical and pathological features. Many efforts have been made to discover the genetic and molecular features of colorectal cancer, and there is more and more evidence that these features determine the prognosis and response to (targeted) treatment. Colorectal cancer is a heterogeneous disease, with three known major molecular groups. The most common is the chromosomal instable group, characterized by an accumulation of mutations in specific oncogenes and tumor suppressor genes. The second is the microsatellite instable group, caused by dysfunction of DNA mismatch repair genes leading to genetic hypermutability. The CpG Island Methylation phenotype is the third group, distinguished by hypermethylation. Colorectal cancer subtyping has also been addressed using genome-wide gene expression profiling in large patient cohorts and recently several molecular classification systems have been proposed. In this review we would like to provide an up-to-date overview of the genetic aspects of colorectal cancer. PMID:24714764

    The objectives of this phase I-II trial were to assess the toxicity, immunological and clinical responses induced in 37 patients with stage IV colorectal cancer by the subcutaneous administration of a xenogenic polyantigenic vaccine (XPV) prepared from disrupted murine melanoma (B16) and carcinoma (LLC) cells. An inducing course of vaccinotherapy consisted of 10 immunizations (5 at weekly and 5 at fortnight intervals). Twenty-four hours later each of first 5 vaccinations the patient was subcutaneously given a low dose of the recombinant interleukin-2 (IL-2). A consolidating course of vaccinotherapy consisted of monthly vaccinations. No grade III or IV toxicities, but also laboratory and clinical signs of developing systemic autoimmune disorders were noted in any XPV-treated patient. A significant increase in cell-mediated immunoreactivity to both LLC and B16 antigens (Ags) occurred in the patients after inducing vaccinations, as determined by delayed-type hypersensitivity (DTH) skin reactions, as well as by blood lymphocyte proliferation responses. Vaccinations also led to increased cell-mediated reactivity to murine non-tumor, spleen cell (SC)-associated Ags. This reactivity, however, was not as significant as that to tumor-associated antigens (TAAs). XPV was also found to capable of generating IgG antibody-mediated responses. With immunotherapy concentrations of both interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) detectably elevated in patients' sera, suggesting intensification of T helper 1-/T helper 2-mediated responses in the XPV-treated patients. The average survival of the XPV-treated patients was noticeably superior than was that of the clinically comparable control patients (17 vs 7 months). Collectively the results suggest that xenogenic TAAs are safe to use, able to induce measurable cellular and humoral immune responses, and may be clinically effective in certain colorectal cancer patients.

    Terrestrial heat flow determination is of prime interest for oil industry because it impacts directly maturation histories and economic potential of oil fields. Published systematic heat flow determinations from major oil provinces are however seldom. Robust heat flow determinations in drillholes require logging of undisturbed temperatures and intensive sampling of core material for petrophysical measurements. Temperature logging in exploration drillholes is traditionally conducted during drill breaks or shortly after drilling, resulting in temperatures severely disturbed by mud circulation and coring is restricted to selected intervals. Alternatively, test temperatures, information from electric logs and lithological descriptions of drill cuttings can be used to overcome these limitations. The present contribution introduces new heat flow determinations based on 63 exploration drillholes from the Norwegian North Sea, the Mid Norway Margin and the Barents Shelf. Our analyses are based on released DST temperatures, precise lithological descriptions of drill cuttings, previously measured rock matrix thermal conductivities and established porosity laws. For the sake of comparison, we carefully review previous heat flow studies carried out both onshore and offshore Norway. Our results suggest median heat flow values of 64 mW/m2, 65 mW/m2 and 72 mW/m2 for the North Sea, the Mid Norway Margin (mainly the Trøndelag Platform) and the SW Barents Shelf respectively. In detail, heat flow increases by ~ 10 mW/m2 from the southern Norwegian North Sea towards the Mid Norway Margin. This result appears to be in very good agreement with seismic tomographic studies suggesting northward thinning of the underlying mantle lithosphere. Our results together with published marine heat flow data from the Mid Norway Margin suggest a gradual decrease in heat flow levels from both the North Sea and the Trøndelag Platform towards the centres of the deep Møre and Vøring basins.

The Barents Shelf shows significantly high heat flow, suggesting lateral transfer of heat from the mantle of the adjacent young ocean. In detail, heat flow increases by ~ 10 mW/m2 from the southern Norwegian North Sea towards the Mid Norway Margin.

    Background and Objectives: Laparoscopic colorectal surgery is an established safe procedure with demonstrated benefits. Proficiency in this specialty correlates with the volume of cases. We examined training in this surgical field for both general surgery and colon and rectal surgery residents to determine whether the number of cases needed for proficiency is being realized. Methods: We examined the Accreditation Council for Graduate Medical Education (ACGME) and American Board of Colorectal Surgeons (ABCRS) operative statistics for graduating general surgery and colon and rectal surgery residents. Results: Although the number of advanced laparoscopy cases had increased for general surgery residents, there was still a significant gap in case volume between the average number of laparoscopic colorectal operations performed by graduating general surgery residents (21.6) and those performed by graduating colon and rectal surgery residents (81.9) in 2014. Conclusion: There is a gap between general surgery and colon and rectal surgery residency training for laparoscopic colorectal surgery. General surgery residents are not meeting the volume of cases necessary for proficiency in colorectal surgery. This deficit represents a structural difference in training. PMID:27493468

A free medical examination with compensation for lost earnings was offered to the forest workers in three areas of eastern Norway. Sixty-six per cent attended (413 workers, of whom 296 used chain saws). The prevalence of Raynaud's phenomenon (RP) was 47% in chain saw operators, 14% in forest workers not exposed to vibration, and 9% in 302 indoor workers not exposed to vibration. The high prevalence of RP in chain saw operators was attributed to a traumatic vasospastic disease (TVD). The average time of latency was eight years. The standard symptoms of TVD were attacks of blanching and numbness. Cyanosis and pain occurred rarely. In subsamples, measurements of tactile two-point discrimination and maximal isometric muscle strength (hand grip and finger pressure) as well as x-ray examinations of the wrists and the hands gave no evidence of vibration injury to peripheral nerves, muscles, bones, or joints.

    Bilinguals who learned English late in life (late bilinguals) as opposed to those who learned English early in life (early bilinguals) differ in their perception of phonemic distinctions. Age of acquisition of a second language as well as depth of immersion into English is influenced by perceptual differences of phonemic contrasts between monolinguals and bilinguals, with consequences for speech production. The phonemes /v/ and /w/ are from the same category in Norwegian, rendering them perceptually indistinguishable to the native Norwegian listener. In English, /v/ and /w/ occupy two categories. Psychoacoustic testing on this phonemic distinction in the current study will compare perceptual abilities of monolingual English and bilingual Norwegian/English listeners. Preliminary data indicates that Norwegian/English bilinguals demonstrate varying perceptual abilities for this phonemic distinction. A series of speech sounds have been generated by an articulatory synthesizer, the Tube Resonance Model, along a continuum between the postures of /v/ and /w/. They will be presented binaurally over headphones in an anechoic chamber at a sound pressure level of 75 dB. Differences in the perception of the categorical boundary between /v/ and /w/ among English monolinguals and Norwegian/English bilinguals will be further delineated.

    CEA and CA19-9 are the two most common tumor markers for colorectal cancer that are currently utilized clinically. The positive rate of CEA is 40-60% and that of CA19-9 is 30-50%. Simultaneous use of the two markers is useful in evaluating the therapeutic effect and monitoring the recurrence of advanced colorectal cancer. Surgical specimens may also provide useful information for the appropriate treatment of patients. Using surgically resected lymph nodes, we examined micrometastasis to assess the spread of the cancer cells and the malignant potential of colorectal cancer. Immunohistochemical analysis using anti-cytokeratin antibody revealed no significant impact of micrometastasis on patient prognosis, while RT-PCR assay using CEA as a genetic marker suggested a positive value in predicting a rapid recurrence. Among various molecular markers, we found that CDC25B phosphatase was a powerful prognostic factor for colorectal cancer. Diagnosis of the existence and malignant potential of cancer cells, together with serum tumor marker levels, may help to construct a more useful system for the better treatment of colorectal cancer.

    Most of subepithelial lesion (SEL) being identified was accidentally discovered as small bulging lesion covered with normal mucosa from endoscopic screening. The type of treatment and prognosis vary depending on the type of tumor, it would be crucial to perform an accurate differential diagnosis. Since the differentiation of SEL relied on the indirect findings observed from the mucosal surface using an endoscopy only in the past, it was able to confirm the presence of lesion only but difficult to identify complex detailed nature of the lesion. However, after the endoscopic ultrasonography (EUS) was introduced, it became possible to identify extrinsic compression, and size of intramural tumors, internal properties and contour so that it gets possible to have differential diagnosis of lesions and prediction on the lesion whether it is malignant or benign. In addition, the use of EUS-guided fine needle aspiration and EUS-guided core biopsy made it possible to make histological differential diagnosis. This study intended to investigate endoscopic and EUS findings, histological diagnosis, treatment regimen and impression of colorectal SELs. PMID:26240803

    Colorectal cancer is a heterogeneous disease that afflicts a large number of people in the United States. The use of animal models has the potential to increase our understanding of carcinogenesis, tumor biology, and the impact of specific molecular events on colon biology. In addition, animal models with features of specific human colorectal cancers can be used to test strategies for cancer prevention and treatment. In this review we provide an overview of the mechanisms driving human cancer, we discuss the approaches one can take to model colon cancer in animals, and we describe a number of specific animal models that have been developed for the study of colon cancer. We believe that there are many valuable animal models to study various aspects of human colorectal cancer. However, opportunities for improving upon these models exist. PMID:23076650

    2016-01-01

    This paper investigates possible attrition/change in the gender system of Norwegian heritage language spoken in America. Based on data from 50 speakers in the Corpus of American Norwegian Speech (CANS), we show that the three-gender system is to some extent retained, although considerable overgeneralization of the masculine (the most frequent gender) is attested. This affects both feminine and neuter gender forms, while declension class markers such as the definite suffix remain unaffected. We argue that the gender category is vulnerable due to the lack of transparency of gender assignment in Norwegian. Furthermore, unlike incomplete acquisition, which may result in a somewhat different or reduced gender system, attrition is more likely to lead to general erosion, eventually leading to complete loss of gender.

    2015-01-01

    Diet has an important role in the development of colorectal cancer. In the past few decades, findings from extensive epidemiologic and experimental investigation have linked consumption of several foods and nutrients to the risk of colorectal neoplasia. Calcium, fiber, milk, and whole grain have been associated with a lower risk of colorectal cancer, and red meat and processed meat with an increased risk. There is substantial evidence for the potential chemopreventive effects of vitamin D, folate, fruits and vegetables. Nutrients and foods may also interact, as a dietary pattern, to influence colorectal cancer risk. Diet likely influences colorectal carcinogenesis through several interacting mechanisms. These include the direct effects on immune responsiveness and inflammation, and the indirect effects of over-nutrition and obesity—risk factors for colorectal cancer. Emerging evidence also implicates the gut microbiota as an important effector in the relationship between diet and cancer. Dietary modification therefore has the promise of reducing colorectal cancer incidence. PMID:25575572

    Published reports have revealed increased risk of colorectal cancers in people exposed to chlorinated drinking water or chemical derivatives of chlorination. Oestrogen plays a dual positive functions for diminishing the possibilities of such risk by reducing the entrance, and increasing the excretion, of these chemicals. In addition, there are supplementary measures that could be employed in order to reduce this risk further, such as boiling the drinking water, revising the standard concentrations of calcium, magnesium and iron in the public drinking water and prescribing oestrogen in susceptible individuals. Hypo-methylation of genomic DNA could be used as a biological marker for screening for the potential development of colorectal cancers. PMID:27096035

    The trillions of bacteria that naturally reside in the human gut collectively constitute the complex system known the gut microbiome, a vital player for the host’s homeostasis and health. However, there is mounting evidence that dysbiosis, a state of pathological imbalance in the gut microbiome is present in many disease states. In this review, we present recent insights concerning the gut microbiome’s contribution to the development of colorectal adenomas and the subsequent progression to colorectal cancer (CRC). In the United States alone, CRC is the second leading cause of cancer deaths. As a result, there is a high interest in identifying risk factors for adenomas, which are intermediate precursors to CRC. Recent research on CRC and the microbiome suggest that modulation of the gut bacterial composition and structure may be useful in preventing adenomas and CRC. We highlight the known risk factors for colorectal adenomas and the potential mechanisms by which microbial dysbiosis may contribute to the etiology of CRC. We also underscore novel findings from recent studies on the gut microbiota and colorectal adenomas along with current knowledge gaps. Understanding the microbiome may provide promising new directions towards novel diagnostic tools, biomarkers, and therapeutic interventions for CRC. PMID:24855012

  20. Minilaparoscopic Colorectal Resections: Technical Note

    2012-01-01

    Laparoscopic colorectal resections have been shown to provide short-term advantages in terms of postoperative pain, general morbidity, recovery, and quality of life. To date, long-term results have been proved to be comparable to open surgery irrefutably only for colon cancer. Recently, new trends keep arising in the direction of minimal invasiveness to reduce surgical trauma after colorectal surgery in order to improve morbidity and cosmetic results. The few reports available in the literature on single-port technique show promising results. Natural orifices endoscopic techniques still have very limited application. We focused our efforts in standardising a minilaparoscopic technique (using 3 to 5 mm instruments) for colorectal resections since it can provide excellent cosmetic results without changing the laparoscopic approach significantly. Thus, there is no need for a new learning curve as minilaparoscopy maintains the principle of instrument triangulation. This determines an undoubted advantage in terms of feasibility and reproducibility of the procedure without increasing operative time. Some preliminary experiences confirm that minilaparoscopic colorectal surgery provides acceptable results, comparable to those reported for laparoscopic surgery with regard to operative time, morbidity, and hospital stay. Randomized controlled studies should be conducted to confirm these early encouraging results. PMID:22548166

    1999-04-01

    During Norway`s 15th licensing round in 1996, five deepwater areas were opened for exploration drilling. All blocks are situated outside the continental shelf in the Norwegian Sea, west of mid-Norway. The seabed and location conditions were studied by the Norwegian Deepwater Project, a joint venture of the operator companies who were awarded blocks in these new unexplored areas. Results of the study revealed that the weather and sea conditions in these remote areas would be among the toughest in the world. Strong return currents from the Arctic Ocean bring undercooled water to these locations, lowering the seabed temperature to as low as {minus}2 C. Because all the blocks are situated outside the Norwegian continental shelf, the water depth is in the range of 2,600--5,000 ft (800--1,600 m). Typical deepwater conditions are present in most of the deepwater locations in the Norwegian Sea. The conditions that posed additional challenges to the drilling operation were poorly consolidated sediments, shallow water flow zones, hydrate destabilization and ooze sediments. The paper describes sediment consolidation, shallow water flow, hydrates, development of deepwater cement slurries, a field case, and future cementing operations in Norway.

  18. No indication of Coxiella burnetii infection in Norwegian farmed ruminants

    PubMed Central

    2012-01-01

    Background Infection with Coxiella burnetii, the cause of Q-fever, has never been detected in Norwegian animals. Recognising the increasing prevalence of the infection in neighbouring countries, the aim of the study was to perform a survey of Norwegian farmed ruminants for the prevalence of C. burnetii infection. Results Milk and blood samples from more than 3450 Norwegian dairy cattle herds, 55 beef cattle herds, 348 dairy goat herds and 118 sheep flocks were serologically examined for antibodies against C. burnetii. All samples were negative for antibodies against C. burnetii. The estimated prevalences of infected herds were 0 (95% confidence interval: 0% - 0.12%), 0 (0% - 12%), 0 (0% - 1.2%) and 0 (0% - 10%) for dairy cattle herds, beef cattle herds, goat herds and sheep flocks, respectively. Conclusions The study indicates that the prevalence of C. burnetii infection in farmed Norwegian ruminants is low, and it cannot be excluded that Norway is free of the infection. It would be beneficial if Norway was able to maintain the current situation. Therefore, preventive measures should be continued. PMID:22607497

    PubMed

    Lavik, N J

    1994-06-10

    In 1945 the Ministry of Justice appointed a committee to conduct a psychiatric examination of Norwegian Nazis. This was done after a proposal from the Norwegian Psychiatric Association on the initiative of Professor Langfeldt, who at that time was head of the Department of Psychiatry at the University of Oslo. An investigation based on a crosscheck between membership of the Nazi party and the Norwegian case register for psychoses for the period 1926-1940 showed 30% more psychoses among the Nazis than in the population as a whole. Other studies tended to support the view that there was a high prevalence of deviant personalities among the Nazis. A study of 340 "front combatants" (not representative of the whole group of 8,000) showed no increase in psychopathology. They had a higher level of intelligence and education than the mean of young Norwegian males. Many of them belonged to strong pro-Nazi families. The studies of pro-Nazi women, especially the very young who had been involved in sexual relationships with German soldiers, are not representative. The findings seem to indicate that many of them lacked family support and had social problems. The studies are discussed in a historical perspective, with some comments about their relevance today.

    2014-05-01

    The aim of this paper is to evaluate and compare the durability, life expectancy and maintenance needs of traditional Norwegian waterproofing concepts to the generally more rigid waterproofing concepts seen in other European countries. The focus will be on solutions for future Norwegian tunnel boring machine railway tunnels. Experiences from operation of newer and older tunnels with different waterproofing concepts have been gathered and analyzed. In the light of functional requirements for Norwegian rail tunnels, some preliminary conclusions about suitable concepts are drawn. Norwegian concepts such as polyethylene panels and lightweight concrete segments with membrane are ruled out. European concepts involving double shell draining systems (inner shell of cast concrete with membrane) and single shell undrained systems (waterproof concrete segments) are generally evaluated as favorable. Sprayable membranes and waterproof/insulating shotcrete are welcomed innovations, but more research is needed to verify their reliability and cost effectiveness compared to the typical European concepts. Increasing traffic and reliance on public transport systems in Norway result in high demand for durable and cost effective solutions.

    PubMed Central

    Jackson, Nicole R.; Hauch, Adam T.; Hu, Tian; Kandil, Emad

    2014-01-01

    Background: Robotic approaches have become increasingly used for colorectal surgery. The aim of this study is to examine the safety and efficacy of robotic colorectal procedures in an adult population. Study Design: A systematic review of articles in both PubMed and Embase comparing laparoscopic and robotic colorectal procedures was performed. Clinical trials and observational studies in an adult population were included. Approaches were evaluated in terms of operative time, length of stay, estimated blood loss, number of lymph nodes harvested, and perioperative complications. Mean net differences and odds ratios were calculated to examine treatment effect of each group. Results: Two hundred eighteen articles were identified, and 17 met the inclusion criteria, representing 4,342 patients: 920 robotic and 3,422 in the laparoscopic group. Operative time for the robotic approach was 38.849 minutes longer (95% confidence interval: 17.944 to 59.755). The robotic group had lower estimated blood loss (14.17 mL; 95% confidence interval: –27.63 to –1.60), and patients were 1.78 times more likely to be converted to an open procedure (95% confidence interval: 1.24 to 2.55). There was no difference between groups with respect to number of lymph nodes harvested, length of stay, readmission rate, or perioperative complication rate. Conclusions: The robotic approach to colorectal surgery is as safe and efficacious as conventional laparoscopic surgery. However, it is associated with longer operative time and an increased rate of conversion to laparotomy. Further prospective randomized controlled trials are warranted to examine the cost-effectiveness of robotic colorectal surgery before it can be adopted as the new standard of care. PMID:25489216

    Until recently, hepatic arterial therapies (HAT) had been used for colorectal liver metastases after failure of first-, second-, and third-line chemotherapies. HAT has gained greater acceptance in patients with liver-dominant colorectal metastases after failure of surgery or systemic chemotherapy. The current data demonstrate that HAT is a safe and effective option for preoperative downsizing, optimizing the time to surgery, limiting non-tumor-bearing liver toxicity, and improving overall survival after surgery in patients with colorectal liver-only metastases. The aim of this review is to present the current data for HAT in liver-only and liver-dominant colorectal liver metastases. PMID:27017870

    Colorectal cancer is the third most common form of cancer and the second leading cause of cancer-related death in the western world. Tumour cells acquire the hallmarks of cancer during the carcinogenic selection process. Cell immortality is one of the principal features acquired during this process which involves the stabilization of telomere length. It is achieved mainly, by telomerase activation. Thus, the discovery of telomeres and telomerase allowed an understanding of the mechanisms by which cells can become immortalized. Different studies have shown that tumour cells have shorter telomeres than nontumour cells and have detected telomerase activity in the majority of tumours. Survival studies have determined that telomere maintenance and telomerase activity are associated with poor prognosis. Taking into account all the results achieved by different groups, quantification and evaluation of telomerase activity and measurement of telomere length may be useful methods for additional biologic and prognostic staging of colorectal carcinoma.

    1986-11-01

    Controversies exist regarding the surgical treatment of the ovaries in women with primary colorectal cancer. A review of the authors' experience and the surgical literature reveals an incidence of ovarian metastases from colorectal cancer of approximately 6 percent. This problem may occur somewhat more frequently in premenopausal women. Resection of the ovaries at the time of colectomy is unlikely to affect survival. Removal of the ovaries at the time of bowel resection will prevent repeat laparotomy to resect an ovarian mass in approximately 2 percent of women with large bowel cancer. Oophorectomy should be performed in all postmenopausal females at the time of primary resection. Oophorectomy should be performed in premenopausal women if any gross abnormality of the ovary is detected or if peritoneal implants are seen at the time of primary resection. PMID:3533472

    Abnormalities in nuclear phenotype and chromosome structure are key features of cancer cells. Investigation of the protein determinants of nuclear subfractions in cancer may yield molecular insights into aberrant chromosome function and chromatin organization and in addition may yield biomarkers for early cancer detection. Here we evaluate a proteomics work flow for profiling protein constituents in subnuclear domains in colorectal cancer tissues and apply this work flow to a comparative analysis of the nuclear matrix fraction in colorectal adenoma and carcinoma tissue samples. First, we established the reproducibility of the entire work flow. In a reproducibility analysis of three nuclear matrix fractions independently isolated from the same colon tumor homogenate, 889 of 1,047 proteins (85%) were reproducibly identified at high confidence (minimally two peptides per protein at 99% confidence interval at the protein level) with an average coefficient of variance for the number of normalized spectral counts per protein of 30%. This indicates a good reproducibility of the entire work flow from biochemical isolation to nano-LC-MS/MS analysis. Second, using spectral counting combined with statistics, we identified proteins that are significantly enriched in the nuclear matrix fraction relative to two earlier fractions (the chromatin-binding and intermediate filament fractions) isolated from six colorectal tissue samples. The total data set contained 2,059 non-redundant proteins. Gene ontology mining and protein network analysis of nuclear matrix-enriched proteins revealed enrichment for proteins implicated in “RNA processing” and “mRNA metabolic process.” Finally, an explorative comparison of the nuclear matrix proteome in colorectal adenoma and carcinoma tissues revealed many proteins previously implicated in oncogenesis as well as new candidates. A subset of these differentially expressed proteins also exhibited a corresponding change at the mRNA level

    ADAMTSs are a family of secreted proteinases that share the metalloproteinase domain with matrix metalloproteinases (MMPs). By acting on a large panel of extracellular substrates, they control several cell functions such as fusion, adhesion, proliferation and migration. Through their thrombospondin motifs they also possess anti-angiogenic properties. We investigated whether ADAMTSs participate in colorectal cancer progression and invasion. Their expression was investigated at both mRNA and protein levels. Using RT-PCR, the expression of ADAMTS-1, -4, -5 and ADAMTS-20 was estimated in colorectal tumors of different cancer stage and anatomic site and 3 cell lines of different aggressiveness. An overexpression of ADAMTS-4 and -5 was observed, especially in tissue samples, whereas ADAMTS-1 and -20 were found to be down-regulated. Western blot analysis further supported the RT-PCR findings, revealing in addition the degradation of ADAMTS-1 and -20 in cancer. In situ expression and localization of ADAMTS-1, -4, -5 and -20 was also investigated by immunohistochemical analysis. Our data suggest a positive correlation between ADAMTS-4 and -5 expression and cancer progression, in contrast with the anti-angiogenic members of the family, ADAMTS-1 and -20, which were found to be down-regulated. Our findings support the notion that overexpression of ADAMTS-4 and ADAMTS-5 in colorectal cancer might be a possible invasive mechanism of cancer cells in order to degrade proteoglycans of ECM.

    Some trials have demonstrated the benefits of maintenance chemotherapy for advanced colorectal cancer. In chemotherapeutic strategies for advanced colorectal cancer, chemotherapy-related toxicity prevention and quality of life(QOL)maintenance are more important than the introduction of a strong regimen, especially when additional surgery is not possible. In Japan, the combination of a folinic acid/5-fluorouracil/oxaliplatin(FOLFOX)regimen and bevacizumab is a popular first-line chemotherapy regimen. However, despite its effectiveness, neuropathy or hand-foot syndrome after 5 or 6 cycles tends to lead to chemotherapy withdrawal. CAIRO3 trial reported the effectiveness of capecitabine and bevacizumab as a maintenance chemotherapy regimen. Additionally, the ML18147 trial demonstrated that bevacizumab beyond progression(BBP)prolonged overall survival(OS)and progression free survival(PFS)in patients with advanced colorectal cancer. Although those trials demonstrated the effectiveness of continuous or maintenance bevacizumab administration, no trials have compared the effectiveness of cytotoxic drugs with bevacizumab as maintenance therapies. Moreover, controversy exists regarding the selection of drugs as a maintenance therapy and the identification of patients who would benefit from maintenance therapy. PMID:25132024

    Colorectal cancer is the fourth most common non-cutaneous malignancy in the United States and the second most frequent cause of cancer-related death. Over the past 12 years, significant progress has been made in the systemic treatment of this malignant condition. Six new chemotherapeutic agents have been introduced, increasing median overall survival for patients with metastatic colorectal cancer from less than 9 months with no treatment to approximately 24 months. For patients with stage III (lymph node positive) colon cancer, an overall survival benefit for fluorouracil-based chemotherapy has been firmly established, and recent data have shown further efficacy for the inclusion of oxaliplatin in such adjuvant treatment programs. For patients with stage II colon cancer, the use of adjuvant chemotherapy remains controversial, but may be appropriate in a subset of individuals at higher risk for disease recurrence. Ongoing randomized clinical trials are evaluating how best to combine currently available therapies, while smaller studies are evaluating new agents, with the goal of continued progress in prolonging life among patients with metastatic colorectal cancer and increasing cure rates among those with resectable disease.

    Resection of colorectal liver metastases is a treatment standard because patients experience long-term disease-free survival or are even cured after undergoing this procedure. Improved surgical techniques for liver resection in combination with downsizing liver metastases by chemotherapy, interventions to induce liver hypertrophy before resection, and the use of ablative techniques have allowed us to expand the indications for liver surgery and local treatment in situations with limited metastatic colorectal cancer. Resectability and identification of patients who might benefit from liver surgery and local ablative techniques are key factors for the treatment of patients with colorectal cancer. Despite the wide acceptance of liver surgery and ablative techniques, there are many open questions on the management of limited metastatic disease, such as which patients benefit from an aggressive surgical approach, what the indications for ablative and other local techniques are, and what the role of chemotherapy is for patients with resectable or resected disease. Unfortunately, results of randomized trials are only available for a limited number of these questions. PMID:27249722

    Objectives The incidence and survival rate of colorectal cancer in Korea are increasing because of improved screening, treatment technologies, and lifestyle changes. In this aging population, increases in economic cost result. This study was conducted to estimate the economic burden of colorectal cancer utilizing claims data from the Health Insurance Review and Assessment Service. Methods Economic burdens of colorectal cancer were estimated using prevalence data and patients were defined as those who received ambulatory treatment from medical institutions or who had been hospitalized due to colorectal cancer under the International Classification of Disease 10th revision codes from C18-C21. The economic burdens of colorectal cancer were calculated as direct costs and indirect costs. Results The prevalence rate (per 100 000 people) of those who were treated for colorectal cancer during 2010 was 165.48. The economic burdens of colorectal cancer in 2010 were 3 trillion and 100 billion Korean won (KRW), respectively. Direct costs included 1 trillion and 960 billion KRW (62.85%), respectively and indirect costs were 1 trillion and 160 billion (37.15%), respectively. Conclusions Colorectal cancer has a large economic burden. Efforts should be made to reduce the economic burden of the disease through primary and secondary prevention. PMID:24744825

    A priority classification was evaluated according to a modified 'Norwegian model.' Many diseases do not belong to any specific priority category based only on the diagnosis. The classification also depends on the condition's type, site, and phase as well as the patient's age and overall condition. Savings cannot be achieved by the model used because 89% of the patients belonged to the priority categories I-III, the care of which can be classified as necessary. PMID:8707510

    Most of the tectonic and dynamic concepts on the evolution of rifted margins have been developed from either intra-continental rift basins or proximal margin usually characterised by small amounts of crustal thinning. Some of these continental margins also display a high level of volcanic activity along the continent-ocean transition (COT). In such a context, the tectonic evolution of the proto-breakup rift system of the outer Norwegian margin is still problematic, due to sub-basalt imaging and a poor knowledge of the mechanisms involved before, during and slightly after the onset of breakup. Regional analysis and interpretation of multichannel seismic data, potential field data, integrated with refined plate reconstruction and finite-element modelling have provided the opportunity to propose an updated tectonic model for the evolution and segmentation of the Norwegian margin and the early Norwegian-Greenland Sea oceanic domain. Timing of deformation and structural styles observed along the conjugates reflect lateral variations of the rifted system which is influenced by complex inherited features, late magma-tectonic processes and local plate instabilities. We show that the deep structures associated with the volcanic rifted margin are still controversial and not necessarily so magmatic. We have also attempted to investigate the role of localised magmatic intrusion in rift and breakup dynamics and compared the results with our geophysical data, offshore Norway. The thickness, composition and temperature of the underplated and/or intruded bodies seem to be important factors that control lithospheric stretching, basin temperature, rift structure, margin asymmetry and COT formation. We also document the early spreading history of the mid-Norwegian by means of two news recent aeromagnetic surveys which highlight a complex spreading evolution correlated with the onset of microcontinent formation (Jan Mayen microcontinent) and an atypical (mid-Eocene?) magmatic event

    1989-07-01

    Simultaneous wave and current measurements on the Norwegian Shelf were used to estimate the appropriate current to associate with extreme waves in platform design. The primary data consisted of seven years of measurements at Tromsoflaket (71{degrees}30'N, 19{degrees}E, 230 m depth), including 38 storms with peak significant wave heights above 7 m. The maximum wave height and maximum current occurred simultaneously in only one of the 38 storms. The wave and current time-series data were used to calculate the time series of drag load on a simple structure and statistics of wave height and drag load were developed. The data showed that the in-line current that must be added to extreme waves in order to preserve the extreme loads approaches 25 cm/s asymptotically as storm severity increases. Sensitivity studies suggest that this limit is largely insensitive to reasonable variations in current profile, wave kinematics theory, structure geometry, tidal current removal, length of data base, or site location. These results show that the current specified by Norwegian regulatory authorities is conservative, and provide a basis for reducing the design hydrodynamic loads on drag-dominated offshore structures on the Norwegian shelf.

    Colorectal cancer, a clinically diverse disease, is a leading cause of cancer-related death worldwide. Application of novel molecular diagnostic tests, which are summarized in this article, may lead to an improved survival of colorectal cancer patients. Distinction of these applications is based on the different molecular principles found in colorectal cancer (CRC). Strategies for molecular analysis of single genes (as KRAS or TP53) as well as microarray based techniques are discussed. Moreover, in addition to the fecal occult blood testing (FOBT) and colonoscopy some novel assays offer approaches for early detection of colorectal cancer like the multitarget stool DNA test or the blood-based Septin 9 DNA methylation test. Liquid biopsy analysis may also exhibit great diagnostic potential in CRC for monitoring developing resistance to treatment. These new diagnostic tools and the definition of molecular biomarkers in CRC will improve early detection and targeted therapy of colorectal cancer.

    The aim of this observational, population-based study was to compare subjective health complaints (SHC) in Norwegians, living in a Western welfare society, and Maasai people, living in rural Kenya under primitive conditions. An interview-based version of SHC inventory was used. Data from 320 Maasais were compared to data from 1243 Norwegians. The Maasais had significantly higher score than the Norwegians on 23 of 28 items, involving musculoskeletal, "pseudo-neurological" and gastrointestinal complaints. The Maasais, living under primitive conditions, close to nature, seems to have more SHC than Norwegians, living in a modern, highly developed and industrialized country. PMID:17763124

    Tobacco smoking was studied in relation to colorectal cancer in 56 973 Finnish men and women initially free from cancer. Smoking status was determined by a health questionnaire. During a follow-up period of 28 years, from the baseline in 1966-72 to the end of 1994, 457 cases of colorectal cancer occurred. There was no significant association between baseline smoking status and colorectal cancer risk over the total follow-up period. The sex- and age-adjusted relative risk of colorectal cancer between smokers and non-smokers was 1.06 (95% confidence interval 0.84-1.33). For follow-up periods of 11-20 years, however, the relative risk was 1.57 (95% confidence interval 1.09-2.24). In a subgroup in which smoking habits were assessed twice, the relative risk of colorectal cancer among persistent smokers was 1.71 (95% confidence interval 1.09-2.68) compared with others. The results of the present prospective study are consistent with the possibility that smoking increases the risk of colorectal cancer after a relatively long induction period. To clarify the role of smoking in colorectal cancer development, further cohort studies are needed with long follow-up periods and allowing for control of dietary and other potential confounding factors.

    2013-04-01

    The present knowledge on the last deglaciation of the mid-Norwegian continental shelf is still largely based on works from the late 1970's to early 1980's and improved by re-dating shell rich events using the AMS technology in the late 1990´s. These new dating results offered a new chronological framework for the two youngest till units identified in the outer shelf setting of the Mid-Norwegian shelf area using a regional grid of sparker lines. These till units were found to have been deposited around 15000 and 13500 14C BP. The results showed that the Mid-Norwegian shelf ice partly reached the shelf edge as late as ca. 13000 14C BP. Dating from the nearest coastal area show that most of the shelf area had been deglaciated in less than 1000 years. New high-resolution seismic technology, applying the TOPAS parametric echosounder system, the multibeam and the Olex data bathymetric data combined with new AMS dated gravity cores have in the recent year made it possible to approach the deglaciation history in a more detailed way than previously available. The results show that the last glacial maximum ice sheet retreated from the outer shelf area around 15200 14C. The ice sheet readvanced around 14500 14C and created a large end moraine complex and a new minor readvance is interpreted to have occurred around 13700 14C BP before a rapid retreat to the coastal areas during the Bølling period. The two dated ice sheet readvances have occurred within the period of the cold regional climatic event Heinrich 1.

    Objectives To describe how adverse event (AE) rates were monitored and estimated nationally across all Norwegian hospitals from 2010 to 2013, and how they developed during the monitoring period. Monitoring was based on medical record review with Global Trigger Tool (GTT). Setting All publicly and privately owned hospitals were mandated to review randomly selected medical records to monitor AE rates. The initiative was part of the Norwegian patient safety campaign, launched by the Norwegian Ministry of Health and Care Services. It started in January 2011 and lasted until December 2013. 2010 was the baseline for the review. One of the main aims of the campaign was to reduce patient harm. Method To standardise the medical record reviews in all hospitals, GTT was chosen as a standard method. GTT teams from all hospitals reviewed 40 851 medical records randomly selected from 2 249 957 discharges from 2010 to 2013. Data were plotted in time series for local measurement and national AE rates were estimated, plotted and monitored. Results AE rates were estimated and published nationally from 2010 to 2013. Estimated AE rates in severity categories E-I decreased significantly from 16.1% in 2011 to 13.0% in 2013 (−3.1% (95% CI −5.2% to −1.1%)). Conclusions Monitoring estimated AE rates emerges as a potential element in national systems for patient safety. Estimated AE rates in the category of least severity decreased significantly during the first 2 years of the monitoring. PMID:26719311

    Investigations during the last decade have demonstrated that the environment of the southernmost parts of Norway are substantially polluted by acid precipitation originating mainly from Central and Western Europe. These areas are also subjected to pollution by long-distance transport of some fairly volatile trace elements such as lead, cadmium, arsenic and selenium. Accordingly, north-south concentration gradients have been demonstrated for these elements in surface soils, in coniferous forest ecosystems, and in certain herbivorous animals. The purpose of the present study was to determine the cadmium burden in Norwegian cervides, with special reference to moose, and to demonstrate possible regional differences in this regard.

    The Norwegian Remote Sensing Experiment in the marginal ice zone north of Svalbard took place in fall 1979. Coordinated passive and active microwave measurements were obtained from shipborne, airborne, and satellite instruments together with in situ observations. The obtained spectra of emissivity (frequency range, 5 to 100 gigahertz) should improve identification of ice types and estimates of ice concentration. Mesoscale features along the ice edge were revealed by a 1.215-gigahertz synthetic aperture radar. Ice edge location by the Nimbus 7 scanning multichannel microwave radiometer was shown to be accurate to within 10 kilometers.

    AIM: To determine, by counting micronucleus (MN) frequencies, whether chromosomal or DNA damage have an effect on the pathogenesis of early colorectal adenocarcinoma (CRC). METHODS: We analyzed MN frequencies in 21 patients with CRC, 24 patients with colon polyps [10 neoplastic polyps (NP) and 14 non-neoplastic polyps (NNP)] and 20 normal controls. RESULTS: MN frequency was significantly increased in CRC patients and in NP patients compared with controls (3.72 ± 1.34, 3.58 ± 1.21 vs 1.97 ± 0.81, P < 0.001). However, there was no difference in the MN frequency between CRC patients and NP patients (P > 0.05). Similarly, there was no difference in the MN frequency between NNP patients (2.06 ± 0.85) and controls (P > 0.05). CONCLUSION: Our results suggest increased chromosome/DNA instabilities may be associated with the pathogenesis of early CRC. PMID:19058310

    Colorectal cancer is the second leading cause of cancer-related mortality in the United States. Therapeutic developments in the past decade have extended life expectancy in patients with metastatic disease. However, metastatic colorectal cancers remain incurable. Numerous agents that were demonstrated to have significant antitumor activity in experimental models translated into disappointing results in extending patient survival. This has resulted in more attention being focused on the contribution of tumor microenvironment to the progression of a number of solid tumors including colorectal cancer. A more complete understanding of interactions between tumor epithelial cells and their stromal elements will enhance therapeutic options and improve clinical outcome. Here we will review the role of various stromal components in colorectal carcinogenesis and discuss the potential of targeting these components for the development of future therapeutic agents.

    The gut microbiota acts as a real organ. The symbiotic interactions between resident micro-organisms and the digestive tract highly contribute to maintain the gut homeostasis. However, alterations to the microbiome caused by environmental changes (e.g., infection, diet and/or lifestyle) can disturb this symbiotic relationship and promote disease, such as inflammatory bowel diseases and cancer. Colorectal cancer is a complex association of tumoral cells, non-neoplastic cells and a large amount of micro-organisms, and the involvement of the microbiota in colorectal carcinogenesis is becoming increasingly clear. Indeed, many changes in the bacterial composition of the gut microbiota have been reported in colorectal cancer, suggesting a major role of dysbiosis in colorectal carcinogenesis. Some bacterial species have been identified and suspected to play a role in colorectal carcinogenesis, such as Streptococcus bovis, Helicobacter pylori, Bacteroides fragilis, Enterococcus faecalis, Clostridium septicum, Fusobacterium spp. and Escherichia coli. The potential pro-carcinogenic effects of these bacteria are now better understood. In this review, we discuss the possible links between the bacterial microbiota and colorectal carcinogenesis, focusing on dysbiosis and the potential pro-carcinogenic properties of bacteria, such as genotoxicity and other virulence factors, inflammation, host defenses modulation, bacterial-derived metabolism, oxidative stress and anti-oxidative defenses modulation. We lastly describe how bacterial microbiota modifications could represent novel prognosis markers and/or targets for innovative therapeutic strategies. PMID:26811603

    1990-01-01

    Colorectal cancer is the second most common malignancy in the United States, and its incidence rates have sharply increased recently, especially in males. Industrial exposures, both occupational and environmental, are important colorectal cancer risk factors that are generally unrecognized by clinicians. Migration studies have documented that colorectal cancer is strongly associated with environmental risk factors. The causal role of occupational exposures is evidenced by a substantial literature associating specific work practices with increased colorectal cancer risks. Industrially related environmental exposures, including polluted drinking water and ionizing radiation, have also been associated with excess risks. Currently, there is a tendency to attribute colorectal cancer, largely or exclusively, to dietary and other lifestyle factors, thus neglecting these industrially related effects. Concerted efforts are needed to recognize the causal role of industrial risk factors and to encourage government and industry to reduce carcinogenic exposures. Furthermore, cost-effective screening programs for high-risk population groups are critically needed to further reduce deaths from colorectal cancer. 143 references.

    Abstract The population older than 80 years has been increasing. A significant proportion of colorectal diseases that require colorectal resection occur in very elderly patients. However, the benefits of laparoscopy remain controversial in octogenarians. A systematic review and meta-analysis of observational study was performed to compare clinical outcomes between laparoscopic versus open colorectal resection in octogenarians. The PubMed, EMBASE, Ovid, Web of Science, and Cochrane databases from the years 1990 to 2015 were searched for studies that compare surgical outcomes between laparoscopic and open colorectal resection in octogenarians (≥80 years old). Seven eligible studies including 528 laparoscopic and 484 open colorectal resections were identified. Laparoscopic approach was associated with lower rate of mortality (odds ratio [OR] 0.48, P = 0.03), overall complications (OR 0.54, P < 0.001), and prolonged ileus (OR 0.56, P = 0.009), quicker bowel function return (standardized mean difference [SMD] −0.50, P < 0.001), and shorter length of hospital stay (SMD −0.47, P = 0.007). No differences were found in anastomotic leak (OR 1.16, P = 0.72), respiratory complication (OR 0.60, P = 0.07), and reoperation (OR 0.85, P = 0.69). Laparoscopic colorectal resection is as safe as open approach, and the short-term outcomes appear to be more favorable in octogenarians. PMID:26496302

    We conducted a case-control study of the association between subsets of colorectal polyps, including adenomas and serrated polyps, and single-nucleotide polymorphisms (SNPs) related to colorectal cancer through prior genome-wide association studies (GWAS). Participants were enrollees in the Group Health Cooperative (Seattle, Washington) aged 24–79 years who received a colonoscopy from 1998 to 2007, donated a buccal or blood sample, and completed a structured questionnaire. We performed genotyping of 13 colorectal cancer susceptibility SNPs. Polytomous logistic regression models were used to estimate odds ratios and 95% confidence intervals for associations between polyps and the colorectal cancer risk allele for each SNP under a log-additive model. Analyses included 781 controls, 489 cases with adenoma, 401 cases with serrated polyps, and 188 cases with both polyp types. The following SNPs were associated with advanced adenomas: rs10936599, rs10795668, rs16892766, and rs9929218 (P < 0.05). For nonadvanced adenomas and for serrated polyps overall, only rs961253 was statistically significant (P < 0.05). These associations were in the same directions as those in prior colorectal cancer GWAS. No SNP was significantly associated with hyperplastic polyps, and only rs6983267 was significantly associated with sessile serrated polyps, but this association was opposite of that found in colorectal cancer GWAS. Our results suggest that the association between colorectal cancer susceptibility SNPs and colorectal polyps varies by polyp type. PMID:24875374

    The 1995 analysis of the petroleum resources of Norway is based on a play analysis. The input to the 1995 analysis is updated and refined compared with the analysis of 1993. The analysis makes a major distinction between unconfirmed play models and plays confirmed by discoveries. The unconfirmed plays have a higher risk and a greater range of uncertainty in the resource estimates compared to the confirmed plays. The effect of the unconfirmed plays on the estimates within different exploration areas is discussed. The unconfirmed play models are an important aspect of the exploration in the new exploration areas north of 62{degrees}N. The total estimate for the Norwegian Shelf is well within the estimate given in the 1993 analysis, but there are some adjustments in the relative importance of the different exploration provinces. Much emphasis is placed on incorporating historical exploration data and statistics to calibrate the play models. This includes rate of success and field size distributions of the individual play models and exploration provinces. Major confirmed plays in the North Sea have a rate of success of about 30% and show a good fit to a log normal field size distribution. Based on the log normal distribution it is possible to give prognosis for the size distribution of the undiscovered accumulation. This has made it possible to work out an economic analysis of the profitability of future exploration on the Norwegian Continental Shelf.

  20. Structural evolution and petroleum potential of the Norwegian Barents Sea

    The tectonic history of the Norwegian Barents Sea has provided potential hydrocarbon traps in clastic reservoirs associated with rotated fault blocks, compressional anticlines and salt domes. Significant stratigraphic potential also resides in Paleozoic carbonates. Drilling in the Hammerfest Basin has yielded large gas discoveries in rotated fault blocks, but other trapping concepts remain relatively untested. The undrilled arm north of 74{degrees} 30 minutes N, currently being mapped by the Norwegian Petroleum Directorate using exclusive seismic and geological data from shallow boreholes, represents a significant area for future exploration. Prospectivity is critically dependent on the scaling of traps following Neogene uplift of large areas of the Barents platform. The area is dominated by structural trends inherited from the Caledonian and older orogens. Carboniferous rifting established a system of half grabens and intervening highs, followed by late Permian faulting in the west which initiated regional subsidence continuing into the early Jurassic. Fault reactivation in early Triassic times triggered salt diapirism and provided structural control for the formation of Triassic shelf margins. During the late Jurassic-early Cretaceous western basins underwent tectonic subsidence, while the northeastern platform arm was subject to gentle compression. In the late Cretaceous salt was reactivated in the Nordkapp Basin and compressional structures developed west of the Loppa High. Further subsidence of the western basins was promoted by late Mesozoic and early Tertiary transtensional movements along the North Atlantic rift system. Subsequent regional compression in these basins, and basin inversion east of the Loppa High, are of post-Eocene age.

    The relationships between perception of risk, behavior and involvement in accidents are receiving increased attention in the offshore oil industry. How employees perceive the risk they are exposed to during the conduct of their work may contribute to an understanding of risk management and thereby to the safety of their working conditions. A self-completion questionnaire survey was carried out among employees on a representative sample of offshore oil installations in the Norwegian part of the North Sea in 1990. In 1994 a follow-up study was carried out. A total of 915 respondents replied to our questionnaire in 1990 and 1138 in 1994. The studies were financed by the Norwegian Petroleum Directorate. There were significantly fewer of the personnel who felt at risk in 1994 compared to 1990 and a greater percentage of the personnel were satisfied with the safety and contingency measures and experienced job stress to a greater extent in 1990 than they did in 1994. Emotional reactions caused by potentially-hazardous risk sources were dependent on the respondents perceived controllability of the risk sources. The study also showed that there were significant positive correlations between organizational factors, safety status, perceived risk, and accidents. However, safety cannot be improved by changing risk perception. It is the factors that cause variations in risk perception as well as behavior and safety which should be the focus of safety promotion.

  2. Heteronormative consensus in the Norwegian same-sex adoption debate?

    This article investigates the Norwegian newspaper debate (1998-2002) on the right of homosexual couples to adopt children. It identifies two patterns of meaning within which both anti-adoption and pro-adoption sides of the debate were located: 1) the nuclear family as reference point; and 2) a focus on innate qualities. Parallell to a continuous liberalization of sexualities in Norway we seem to witness a consensus on heteronormativity in Norway on both sides of the debate as the basic axiom in public discussions on homosexuality and adoption. In this article, we explore the nature of the heteronormative arguments and the reason for their appearance in this particular debate. The two patterns of meaning reproduce a perception of lesbians and gays as either a worthy or unworthy minority. These findings may be seen as reflecting fundamental positions regarding the Norwegian modernization project, where both sides of the debate see homosexuality as a central symbol. State feminism may also have played the role of reinforcing gender categories and thereby served as an important condition of possibility for contemporary heteronormativity. PMID:19197645

    A quantitative survey of Saprolegnia spp. in the water systems of Norwegian salmon hatcheries was performed. Water samples from 14 salmon hatcheries distributed along the Norwegian coastline were collected during final incubation in the hatcheries. Samples of inlet and effluent water were analyzed to estimate Saprolegnia propagule numbers. Saprolegnia spores were found in all samples at variable abundance. Number of spores retrieved varied from 50 to 3200 L(-1) in inlet water and from 30 to >5000 L(-1) in effluent water. A significant elevation of spore levels in effluent water compared to inlet water was detected. The estimated spore levels were related to recorded managerial and environmental parameters, and the number of spores in inlet water and temperature was the factor having most influence on the spore concentration in the incubation units (effluent water). Further, the relative impact of spore concentration on hatching rates was investigated by correlation analysis. From this was found that even high spore counts did not impact significantly on hatching success. PMID:26123005

    At the Faculty of Health Sciences, Oslo University College there is a growing recognition of the need for cultural competency training among students at the bachelor programmes. At the Mensendieck-physiotherapy bachelor programme the students are engaged in leading physical activity groups for Muslim women. This qualitative study describes ethnically Norwegian students experiencing cultural diversity in practice. Twenty-two female physiotherapy students participated in the interviews; 6 students were interviewed individually by telephone, and 16 students were interviewed in person in 8 pairs. The students' framework for dealing with diversity is based on preconceived notions about Muslim women and is reflected in two particular ways. One is how the values and norms of Norwegian "ideology of sameness" are pursued by the students. The other is how the students constructed images of the women as "the others." The interview responses indicate difficulties in uniting the reality of diversity and the "need" for integration. The curriculum requires additional attention on cultural competency for health care professionals in a multicultural society. PMID:21682583

    Background There is a general perception that train drivers and conductors may be at increased risk of developing noise-induced hearing loss. Aims To study job-related hearing loss among train drivers and train conductors. Methods Audiograms from train drivers and train conductors were obtained from the medical records of the occupational health service of the major Norwegian railway company. The results were compared with audiograms from an internal control group of railway workers and an external reference group of people not occupationally exposed to noise. The monaural hearing threshold level at 4kHz, the mean binaural value at 3, 4 and 6kHz and the prevalence of audiometric notches (≥25 dB at 4kHz) were used for comparison. Results Audiograms were available for 1567 drivers, 1565 conductors, 4029 railway worker controls and 15 012 people not occupationally exposed to noise. No difference in hearing level or prevalence of audiometric notches was found between study groups after adjusting for age and gender. Conclusions Norwegian train drivers and conductors have normal hearing threshold levels comparable with those in non-exposed groups. PMID:24204021

    2016-08-01

    Colorectal cancer (CRC) is the third most common cause of cancer death in men and women in the United States. The main goals of screening are to prevent carcinogenesis (via adenoma detection and removal) and detect cancer at an early, curable stage. CRC mortality is steadily dropping in the United States, partly because of greater screening utilization. However, nearly 1 in 3 average-risk people are not up to date with standard CRC screening recommendations. This review surveys a wide range of CRC biomarkers in various stages of development, which may offer attractive risk stratification tools; a few have reached the commercial stage. If widely accepted, these tools may contribute to shift CRC screening practices away from 1-step colonoscopy to a 2-step risk stratification process of predictive biomarker measurements followed by colonoscopy for lower-risk patients with a positive result. Such strategies could potentially increase the rate of CRC screening. PMID:27496118

    Colorectal cancers (CRC) are one of the most common causes of morbidity and mortality in high-income countries. Targeted screening programs have resulted in early treatment and a substantial decrease in mortality. However, treatment strategies for CRC still require improvement. Understanding the etiology and pathogenesis of CRC would provide tools for improving treatment of patients with this disease. It is only recently that deregulation of the protein synthesis apparatus has begun to gain attention as a major player in cancer development and progression. Among the numerous steps of protein synthesis, deregulation of the process of translation initiation appears to play a key role in cancer growth and proliferation. This manuscript discusses a fascinating and rapidly growing field exploring translation initiation as a fundamental component in CRC development and progression and summarizing CRC treatment perspectives based on agents targeting translation initiation.

    Colorectal cancer (CRC) is one of the major cancers in the world and second death-causing cancer in the US. CRC development involves genetic and epigenetic alterations. Changes in DNA methylation status are believed to be involved at different stages of CRC. Promoter silencing via DNA methylation and hypomethylation of oncogenes alter genes’ expression, and can be used as a tool for the early detection of colonic lesions. DNA methylation use as diagnostic and prognostic marker has been described for many cancers including CRC. CpG Islands Methylator Phenotype (CIMP) is one of the underlying CRC mechanisms. This review aims to define methylation signatures in CRC. The analysis of DNA methylation profile in combination with the pathological diagnosis would be useful in predicting CRC tumors’ evolution and their prognostic behavior. PMID:25580099

    Colorectal cancer (CRC) is highly prevalent worldwide, and despite notable progress in treatment still leads to significant morbidity and mortality. The use of nanoparticles as a drug delivery system has become one of the most promising strategies for cancer therapy. Targeted nanoparticles could take advantage of differentially expressed molecules on the surface of tumor cells, providing effective release of cytotoxic drugs. Several efforts have recently reported the use of diverse molecules as ligands on the surface of nanoparticles to interact with the tumor cells, enabling the effective delivery of antitumor agents. Here, we present recent advances in targeted nanoparticles against CRC and discuss the promising use of ligands and cellular targets in potential strategies for the treatment of CRCs. PMID:27529192

    Now colorectal cancer is the second most common cancer in males and the fourth most common cancer in females in Korea. Since most of colorectal cancers occur after the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are one of the most effective methods to prevent colorectal cancer. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish Korean guideline for colorectal cancer screening and polyp detection. The guideline was developed by the Korean Multi-Society Take Force and we tried to establish the guideline by evidence-based methods. Parts of the statements were draw by systematic reviews and meta-analyses. Herein we discussed epidemiology of colorectal cancers and adenomas in Korea and optimal methods for screening of colorectal cancer and detection of adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.

    Norwegian Spring Spawning herring (NSSH) Clupea harengus L. spawn on coastal banks along the west coast of Norway. The larvae are generally transported northward in the Norwegian Coastal Current (NCC) with many individuals utilizing nursery grounds in the Barents Sea. The recruitment to this stock is highly variable with a few years having exceptionally good recruitment. The principal causes of recruitment variability of this herring population have been elusive. Here we undertake an event analysis using data between 1948 and 2010 to gain insight into the physical conditions in the NCC that coincide with years of high recruitment. In contrast to a typical year when northerly upwelling winds are prominent during spring, the years with high recruitment coincide with predominantly southwesterly winds and weak upwelling in spring and summer, which lead to an enhanced northward coastal current during the larval drift period. Also in most peak recruitment years, low-salinity anomalies are observed to propagate northward during the spring and summer. It is suggested that consistent southwesterly (downwelling) winds and propagating low-salinity anomalies, both leading to an enhanced northward transport of larvae, are important factors for elevated recruitment. At the same time, these conditions stabilize the coastal waters, possibly leading to enhanced production and improved feeding potential along the drift route to Barents Sea. Further studies on the drivers of early life history mortality can now be undertaken with a better understanding of the physical conditions that prevail during years when elevated recruitment occurs in this herring stock.

    Consumption of road salt in Norway, used to improve winter road conditions, has been tripled during the last two decades, and there is a need to quantify limits for optimal use of road salt to avoid further environmental harm. The purpose of this study was to implement methodology to estimate chloride concentration in any given water body in Norway. This goal is feasible to achieve if the complexity of solute transport in the landscape is simplified. The idea was to keep computations as simple as possible to be able to increase spatial resolution of input functions. The first simplification we made was to treat all roads exposed to regular salt application as steady state sources of sodium chloride. This is valid if new road salt is applied before previous contamination is removed through precipitation. The main reasons for this assumption are the significant retention capacity of vegetation; organic matter; and soil. The second simplification we made was that the groundwater table is close to the surface. This assumption is valid for major part of Norway, which means that topography is sufficient to delineate catchment area at any location in the landscape. Given these two assumptions, we applied spatial functions of mass load (mass NaCl pr. time unit) and conditional estimates of normal water balance (volume of water pr. time unit) to calculate steady state chloride concentration along the lake perimeter. Spatial resolution of mass load and estimated concentration along the lake perimeter was 25 m x 25 m while water balance had 1 km x 1 km resolution. The method was validated for a limited number of Norwegian lakes and estimation results have been compared to observations. Initial results indicate significant overlap between measurements and estimations, but only for lakes where the road salt is the major contribution for chloride contamination. For lakes in catchments with high subsurface transmissivity, the groundwater table is not necessarily following the

    Rates of monoterpene emissions from Scots pine (Pinus sylvestris) and Norwegian spruce (Picea abies) have been measured at four sites in Sweden with a dynamic flow chamber technique. Forest floor emissions have been made in the pine forest with the static chamber technique. Sampling was done with Tenax TA and analysis and detection by GC and ion trap detection. The compounds Δ3-carene and α-pinene were the predominant terpenes emitted from the crown and floor of the Scots pine forest. Alpha-pinene was the main terpene emitted from Norwegian spruce at the sites in southern and central Sweden, while Δ3-carene was predominant at the northern site. The relative composition of the emission of both species underwent changes in early spring and fall. Emission rates, normalized to temperature, were seen to vary diurnally with a maximum at midday, and seasonally with maxima in early May and October, and a summer maximum in June-July. The possible dependence of the emission rate on needle growth rate and other plant-physiological processes is discussed. A higher emission rate and different relative composition of the emission was seen to occur when the vegetation was wet, as compared to dry vegetation. The emission from the pine forest floor was seen to have a composition different from that of the crown and a seasonality of the rate similar to that of the crown. The ground emission could not be explained by sources in the litter or ground vegetation alone, and it is suggested that the root system of the trees is also an emission source. The emission rate from the pine forest floor was of the order of 30% of the crown emission. The July rate of emission from the crown of Scots pine, normalized to 20°C and averaged over four sites in Sweden, was 0.8 ± 0.4 μg (gdw (grams dry weight) h)-1, and for Norwegian spruce, 0.5 ± 0.7 μg(gdw h)-1.

    Documentation of glacier changes is a key element for reconstruction of past climate variability and early detection of global climate change. In this paper, records of Holocene glacier variations in different regions in Norway have been synthesised. During the period from approximately 8000 to 4000 cal. yr BP, most glaciers in Norway were completely melted away at least once due to high summer temperatures and/or reduced winter precipitation. Lichenometrically and historically dated moraines at Jostedalsbreen, in Jotunheimen, at Hardangerjøkulen, and at Folgefonna were used to extend records of glacier length variations back to their maximum position during the 'Little Ice Age'. The timing of the maximum 'Little Ice Age' glacial advance in different parts of southern Norway varied considerably, ranging from the early 18th century to the late 19th century. Cumulative glacier length variations of glaciers in southern Norway show an overall retreat from ˜ AD 1750 to the 1930s-40s. Thereafter, most Norwegian glaciers retreated significantly. Short maritime outlet glaciers with a short response time (< 10-15 yr) started to advance in the mid-1950s, whereas long outlet glaciers with longer frontal time lag (> 15-20 yr) continued their retreat to the 1980s. In the 1990s, however, several of the maritime glaciers started to advance as a response to higher winter accumulation during the first part of the 1990s. Since 2000 most of the observed glaciers have retreated remarkably fast (annual frontal retreat > 100 m) mainly due to high summer temperatures. The last glacier inventory in Norway published in 1988 shows that there were 1627 glaciers covering a total area of 2609 km 2 with an estimated volume of 164 km 3. Modern climate-glacier relationships from mass balance data in Scandinavia have been used to present possible effects on the Norwegian glaciers of climate scenarios between 1961-1990 and 2070-2100 presented by the 'RegClim' project.

Objective The study aimed to uncover how the authoritys’ financing policies influence the development of electronic cooperational tools within public health care. Methods An interpretative approach was used in this study. We performed 30 semistructured interviews with vendors, policy makers, and public authorities. Additionally, we conducted an extensive documentation study and participated in 18 workshops concerning information and communication technology (ICT) in Norwegian health care. Results We found that the interorganizational communication in sectors like health care, that have undergone an independent development of their internal information infrastructure would find it difficult to create electronic services that interconnect the organizations because such connections would affect all interconnected organizations within the heterogenic structure. The organizations would, to a large extent, depend on new functionality in existing information systems. Electronic patient records play a central role in all parts of the health care sector and therefore dependence is established to the information systems and theirs vendors. The Norwegian government authorities, which run more than 80% of the Norwegian health care, have not taken extraordinary steps to compensate for this dependency–the government's political philosophy is that each health care institution should pay for further electronic patient record development. However, cooperational tools are complex due to the number of players involved and the way they are intertwined with the overall workflow. The customers are not able to buy new functionalities on the drawing table, while the electronic patient record vendors are not willing to take the economic risk in developing cooperational tools. Thus, the market mechanisms in the domain are challenged. We also found that public projects

    Background Common low-penetrance genetic variants have been consistently associated with colorectal cancer risk. Aim To determine if these genetic variants are associated also with adenoma susceptibility and may improve selection of patients with increased risk for advanced adenomas and/or multiplicity (≥ 3 adenomas). Methods We selected 1,326 patients with increased risk for advanced adenomas and/or multiplicity and 1,252 controls with normal colonoscopy from population-based colorectal cancer screening programs. We conducted a case-control association study analyzing 30 colorectal cancer susceptibility variants in order to investigate the contribution of these variants to the development of subsequent advanced neoplasia and/or multiplicity. Results We found that 14 of the analyzed genetic variants showed a statistically significant association with advanced adenomas and/or multiplicity: the probability of developing these lesions increased with the number of risk alleles reaching a 2.3-fold risk increment in individuals with ≥ 17 risk alleles. Conclusions Nearly half of the genetic variants associated with colorectal cancer risk are also related to advanced adenoma and/or multiplicity predisposition. Assessing the number of risk alleles in individuals within colorectal cancer screening programs may help to identify better a subgroup with increased risk for advanced neoplasia and/or multiplicity in the general population.

    Studies investigating the association between Enterobius vermicularis and allergic conditions have shown conflicting results. This study was conducted to test for any such associations in Norwegian children. Parents were asked to answer questionnaires concerning their children's history of allergies, wheezing or eczema and pinworm infections. Current pinworm infections were diagnosed by microscopic examination of anal scotch tape samples. The data were analysed using logistic regression. Atopic eczema, allergy or wheezing was reported to be confirmed by a physician in 23% of the children (84/364). A possible association between current pinworm infections and food allergy was found, with 17·5% of children without food allergy testing positive for pinworms, compared to 36·8% of children with food allergy (odds ratio 2·9, 95% confidence interval 1·1-8·0). No association was found between past pinworm treatments and present atopic conditions. The association between current E. vermicularis infections and food allergy warrants further study.

    To date very little is still known about the acoustic behavior of Norwegian killer whales, in particular that of individual whales. In this study a unique opportunity was presented to document the sounds produced by five captured killer whales in the Vestfjord area, northern Norway. Individuals produced 14 discrete and 7 compound calls. Two call types were used both by individuals 16178 and 23365 suggesting that they may belong to the same pod. Comparisons with calls documented in Strager (1993) showed that none of the call types used by the captured individuals were present. The lack of these calls in the available literature suggests that call variability within individuals is likely to be large. This short note adds to our knowledge of the vocal repertoire of this population and demonstrates the need for further studies to provide behavioural context to these sounds.

    The aims of this longitudinal study were to investigate a significant threshold shift (STS) among personnel working on board the Royal Norwegian Navy's (RNoN) vessels between 2012 and 2014 and to identify possible determinants of STS. Hearing thresholds were measured by pure tone audiometry in two consecutive examinations (n = 226). STS was defined as an average change in hearing thresholds ≥ + 10 dB at 2,000 Hz, 3,000 Hz, and 4,000 Hz in either ear. Determinants of STS were assessed through a questionnaire. The incidence of STS was 23.0%. Significant determinants of STS were the number of episodes of temporary threshold shifts (TTS) in the Navy, exposure to continuous loud noise during work on board, and the number of gun shots (in the Navy, hunting, and sports). This study indicated a significant association between noise exposure on board Navy vessels and development of STS. PMID:27157689

    All words have properties linked to form, meaning and usage patterns which influence how easily they are accessed from the mental lexicon in language production, perception and comprehension. Examples of such properties are imageability, phonological and morphological complexity, word class, argument structure, frequency of use and age of acquisition. Due to linguistic and cultural variation the properties and the values associated with them differ across languages. Hence, for research as well as clinical purposes, language specific information on lexical properties is needed. To meet this need, an electronically searchable lexical database with more than 1600 Norwegian words coded for more than 12 different properties has been established. This article presents the content and structure of the database as well as the search options available in the interface. Finally, it briefly describes some of the ways in which the database can be used in research, clinical practice and teaching. PMID:25588015

    This article reports the actual participation in leisure activities by a sample of Norwegian adolescents with Down syndrome aged 14. Representing a first generation to grow up in a relatively inclusive context, they live with their families, attend mainstream schools, and are part of common community life. Leisure information was obtained in individual, structured parent interviews, and added to existing longitudinal data from a project following the sample. Generally, the leisure activity may be viewed as varying along a continuum-reaching from formal, organized, and assisted activity participation outside home, to informal, self-organized, and independent participation at home. Formal leisure activities were either organized "for all" or "adapted for disabled." The adolescents' leisure appears as active and social. However, social participation largely involved parents and family, while socializing with other adolescents mainly took place within formal activities adapted for disabled. Clearly, formal and informal activities provide rather different opportunities for social encounters and assistance. PMID:24515503

    An apparently healthy Norwegian lemming (Lemmus lemmus) caught in northern Finland was observed to have a whitish body 0.5 to 1.0 mm in diameter in the external layer of the cerebral cortex. By light microscopy a highly lobulated cyst of Frenkelia sp. was observed. By transmission electron microscopy lemmus) collected in the cyst wall was seen consisting of a parasitophorous vacuolar membrane, an underlying electron-dense layer and a granular layer. The membrane was only slightly convoluted. The protrusions of the cyst wall appeared round but were often not distinctive. A very thin septum divided the interior of the cyst into compartments packed with bradyzoites and maturing zoites. The bradyzoites were elongate measuring 5-8 x 1.5-2 microm. This is the first electron microscopical study of Frenkelia sp. from L. lemmus. PMID:10813619

    Background Emerging evidence suggests differences in colo-rectal cancer in HIV-infected patients (HIV+) compared with HIV− patients. Microsatellite instability (MSI), occurring in a subset of colorectal cancer, is present at a higher rate in certain cancers in HIV+ patients. Colorectal cancer with MSI share some characteristics with those reported for HIV+ colorectal cancer. On this premise, we studied clinical and pathologic features of HIV+ colorectal cancer and evaluated for MSI using matched HIV− colorectal cancer controls. Methods Two nested, matched cohorts were identified from a hospital-based cohort of colorectal cancer patients. HIV+ colo-rectal cancers were identified and random control patients were matched for selected characteristics. Mismatch repair protein (MMR) IHC was performed as the detection method for MSI. Variables were compared between cases and controls using fixed-effects logit modeling to account for matching. Results We included 184 colorectal cancer samples (38 HIV+, 146 HIV− control). Median patient age at colorectal cancer onset was 55. When compared with HIV− colorectal cancer, HIV+patients were more likely to have smoked (P = 0.001), have right-sided colorectal cancer (37% vs. 14%; P = 0.003), and tumor-infiltrating lymphocytes (TIL) above 50/10 high-power fields (21% vs. 7%). There was no difference in MMR protein expression (P = 0.6). HIV+ colorectal cancer patients had reduced overall survival (P = 0.02) but no difference in progression-free survival. Conclusions HIV+ patients developed colorectal cancer at a lower median age than population estimates, had a higher frequency of right-sided disease, and increased TILs, suggesting potential biologic differences compared with uninfected patients. Impact Clinicopathologic differences in colorectal cancer of HIV+ persons may have implications for tumor pathogenesis. PMID:27197294

    SUMMARY The implementation of school policies to support the adoption of physical activity is one of the main strategies recommended to increase physical activity levels among this age group. However, documentation of the effect of such policies is so far limited. The purpose of this study was to explore policy-related practices to support physical activity in Norwegian secondary schools and their association with recess physical activity. Emphasis was given to examine the association between policies and physical activity, over and beyond, individual level interests and environmental factors and to examine cross-level interaction effects. This cross-sectional study was based on a nationally representative sample of Norwegian secondary schools and grade 8 students who participated in the Health Behaviour in School-aged Children (HBSC) 2005/06 study. The final sample comprised 68 schools and 1347 students. Data were collected through questionnaires. The results showed that schools with a written policy for physical activity and schools offering organized non-curricular physical activity several times a week had a higher proportion of students reporting daily participation in recess physical activity. Multilevel logistic regression analysis demonstrated a cross-level main effect of the policy index after controlling for sex, socio-economic status, individual-level interests and the physical environment. A significant contribution of adding the policy index to the prediction of recess physical activity above that provided by the individual-level interests and the physical environment was demonstrated. The results are encouraging and give scientific support to policy documents recommending the implementation of school policies to increase physical activity. PMID:19884244

    The objectives of this study are to measure physicians’ knowledge of the prices of pharmaceuticals, and investigate whether there are differences in knowledge of prices between groups of physicians. This article reports on a survey study of physicians’ knowledge of the prices of pharmaceuticals conducted on a representative sample of Norwegian physicians in the autumn of 2010. The importance of physicians’ knowledge of costs derives from their influence on total spending and allocation of limited health-care resources. Physicians are important drivers in the effort to contain costs in health care, but only if they have the knowledge needed to choose the most cost-effective treatment options. A survey was sent to 1 543 Norwegian physicians, asking them for price estimates and their opinions on the importance of considering the cost of treatment to society as a decision factor when treating their patients. This article deals with a subsection in which the physicians were asked to estimate the price of five pharmaceuticals: simvastatin, alendronate (Fosamax), infliximab (Remicade), natalizumab (Tysabri) and escitalopram (Cipralex). The response rate was 65%. For all the five pharmaceuticals, more than 50% and as many as 83% gave responses that differed more than 50% from the actual drug price. The price of more expensive pharmaceuticals was underestimated, while the opposite was the case for less expensive medicines. The data show that physicians in general have poor knowledge of the prices of the pharmaceuticals they offer their patients. However, the physicians who frequently deal with a drug have better knowledge of its price than those who do not handle a medication as often. The data also suggest that those physicians who agree that cost of care to society is an important decision factor have better knowledge of drug prices. PMID:24040402

    Organizational justice has attracted attention as a predictor of employees' mental and physical health as well as commitment and work outcomes. The lack of a Norwegian translation of an organizational justice scale has precluded its use in Norway. Four dimensions of the organizational justice construct were examined in a Norwegian military context, including facet measures of distributional, interpersonal, and informational justice developed by Colquitt in 2001, in addition to procedural justice developed by Moorman in 1991. Confirmatory factor analyses supported a four-dimensional structure with good internal consistency. Follow-up analyses have suggested that the four dimensions were nested beneath a general, latent organizational justice factor. A positive relationship between organizational justice and self-sacrificial behavior was found, indicating satisfactory construct validity. The results demonstrate that the Norwegian Organizational Justice Scale is a reliable and construct-valid measure of organizational justice in a Norwegian setting. PMID:22662411

    Colorectal cancer (CRC) is the third most common cause of cancer death in the world. The incidence rate (ASR) and age distribution of this disease differ between most of African-Middle-Eastern (AMAGE) and North America and Europe for many reasons. However, in all areas, “CRC” is considered as one of the most preventable cancers, because it might develop from variant processes like polyps and IBD in addition to the genetic pathogenesis which became very well known in this disease. We tried in this paper to review all the possible reasons of the differences in incidence and age between the west and AMAGE. Also we reviewed all the mutations that lead to the hereditary and familiar clustering of this disease with the correlations with the surrounding food and environment of different areas. Then, we focused on the precancerous pathology of this disease with special focusing on early detection depending on new endoscopy technology and most important genetic studies. We lastly reviewed the evidence of some of the surveillance and put suggestions about future surveillance programs and how important those programs are on the psychological aspect of the patients and their families.

    Colorectal cancer (CRC) develops through a multistage process that results from the progressive accumulation of genetic mutations, and frequently as a result of mutations in the Wnt signaling pathway. However, it has become evident over the past two decades that epigenetic alterations of the chromatin, particularly the chromatin components in the promoter regions of tumor suppressors and oncogenes, play key roles in CRC pathogenesis. Epigenetic regulation is organized at multiple levels, involving primarily DNA methylation and selective histone modifications in cancer cells. Assessment of the CRC epigenome has revealed that virtually all CRCs have aberrantly methylated genes and that the average CRC methylome has thousands of abnormally methylated genes. Although relatively less is known about the patterns of specific histone modifications in CRC, selective histone modifications and resultant chromatin conformation have been shown to act, in concert with DNA methylation, to regulate gene expression to mediate CRC pathogenesis. Moreover, it is now clear that not only DNA methylation but also histone modifications are reversible processes. The increased understanding of epigenetic regulation of gene expression in the context of CRC pathogenesis has led to development of epigenetic biomarkers for CRC diagnosis and epigenetic drugs for CRC therapy.

    Endoscopic techniques are gaining popularity in the management of colorectal polyps and occasionally superficial cancers. While their use is in many times palliative, they have proven to be curative in carefully selected patients with polyps or malignancies, with less morbidity than radical resection. However, one should note that data supporting local and ablative therapies for colorectal cancer is scarce and may be subject to publication bias. Therefore, for curative intent, these techniques should only be considered in highly select cases as higher rates of local recurrences have also been reported. The aim of this review is to explain the different modalities of local and ablative therapies specific to colorectal neoplasia and explain the indications and circumstances where they have been most successful.

    Colorectal cancer is one of the most common types of cancer. To better understand about the kinetics of cancer growth, mathematical models are used to provide insight into the progression of this natural process which enables physicians and oncologists to determine optimal radiation and chemotherapy schedules and develop a prognosis, both of which are indispensable for treating cancer. This thesis investigates the stability of colorectal cancer mathematical models. We found that continuous saturating feedback is the best available model of colorectal cancer growth. We also performed stability analysis. The result shows that cancer progress in sequence of genetic mutations or epigenetic which lead to a very large number of cells population until become unbounded. The cell population growth initiate and its saturating feedback is overcome when mutation changes causing the net per-capita growth rate of stem or transit cells exceed critical threshold.

    Colorectal carcinoma is the third most prevalent cancer in the world. In the most advanced stages, the use of chemotherapy induces a poor response and is usually accompanied by other tissue damage. Significant progress based on suicide gene therapy has demonstrated that it may potentiate the classical cytotoxic effects in colorectal cancer. The inconvenience still rests with the targeting and the specificity efficiency. The main target of gene therapy is to achieve an effective vehicle to hand over therapeutic genes safely into specific cells. One possibility is the use of tumor-specific promoters overexpressed in cancers. They could induce a specific expression of therapeutic genes in a given tumor, increasing their localized activity. Several promoters have been assayed into direct suicide genes to cancer cells. This review discusses the current status of specific tumor-promoters and their great potential in colorectal carcinoma treatment. PMID:26648599

    The human gastrointestinal tract hosts a complex and vast microbial community with up to 1011-1012 microorganisms colonizing the colon. The gut microbiota has a serious effect on homeostasis and pathogenesis through a number of mechanisms. In recent years, the relationship between the intestinal microbiota and sporadic colorectal cancer has attracted much scientific interest. Mechanisms underlying colonic carcinogenesis include the conversion of procarcinogenic diet-related factors to carcinogens and the stimulation of procarcinogenic signaling pathways in luminal epithelial cells. Understanding each of these mechanisms will facilitate future studies, leading to the development of novel strategies for the diagnosis, treatment, and prevention of colorectal cancer. In this review, we discuss the relationship between colorectal cancer and the intestinal microbiota. PMID:26483877

    Peritoneal seedings of a colorectal tumor represent the second most frequent site of metastasis (after the liver). In the era of 5-fluorouracil (5-FU)-only chemotherapy, the prognosis was poor for colorectal cancer with peritoneal metastases. Within the last few years, new chemotherapeutic and targeted agents have improved the prognosis; however, the response to these treatments seems to be lower than that for liver metastases. The combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have further improved both disease-free survival and overall survival. Keeping this in mind, every patient presenting with peritoneal metastases from colorectal cancer should be evaluated and receive adequate treatment, if possible in the above-mentioned combination. This paper reviews recent advancements in the therapy of peritoneal carcinomatosis. PMID:26424828

Accumulating data have demonstrated that laparoscopic colectomy is associated with better short-term outcomes and equivalent oncologic outcomes when compared with open surgery. However, some controversies regarding the oncologic quality of mini-invasive surgery for rectal cancer exist. Meanwhile, some progresses in colorectal surgery, such as robotic technology, single-incision laparoscopic surgery, natural orifice specimen extraction, and natural orifice transluminal endoscopic surgery, have been made in recent years. In this article, we review the published data and mainly focus on the current status and latest advances of mini-invasive surgery for colorectal cancer. PMID:24589210

    The Norwegian spring-spawning (NSS) herring (Clupea harengus), blue whiting (Micromesistius poutassou) and Northeast Atlantic (NEA) mackerel (Scomber scombrus) are extremely abundant pelagic planktivores that feed in the Norwegian Sea (NS) during spring and summer. This study investigated the feeding ecology and diet composition of these commercially important fish stocks on the basis of biological data, including an extensive set of stomach samples in combination with hydrographical data, zooplankton samples and acoustic abundance data from 12 stock monitoring surveys carried out in 2005-2010. Mackerel were absent during the spring, but had generally high feeding overlap with herring in the summer, with a diet mainly based on calanoid copepods, especially Calanus finmarchicus, as well as a similar diet width. Stomach fullness in herring diminished from spring to summer and feeding incidence was lower than that of mackerel in summer. However, stomach fullness did not differ between the two species, indicating that herring maintain an equally efficient pattern of feeding as mackerel in summer, but on a diet that is less dominated by copepods and is more reliant on larger prey. Blue whiting tended to have a low dietary overlap with mackerel and herring, with larger prey such as euphausiids and amphipods dominating, and stomach fullness and feeding incidence increasing with length. For all the species, feeding incidence increased with decreasing temperature, and for mackerel so did stomach fullness, indicating that feeding activity is highest in areas associated with colder water masses. Significant annual effects on diet composition and feeding-related variables suggested that the three species are able to adapt to different food and environmental conditions. These annual effects are likely to have an important impact on the predation pressure on different plankton groups and the carrying capacity of individual systems, and emphasise the importance of regular

    We report a 63-year-old lady with Cronkhite-Canada syndrome, who developed colorectal cancer. A hemicolectomy was performed, and the tumor specimen was prepared for DNA-analysis and immunohistochemical screening. We found a mutation of p53 gene without APC- and ras-gene alteration and expression of erbB2-protooncogen. The polyps in non-hereditary Cronkhite-Canada-syndrom are neither adenomatous nor hyperplastic, but patients often develop colorectal cancers. The steps of mutation do not follow the adenoma-carcinoma sequence, first described by Vogelstein 1988. This and previous observations suggest that carcinogenesis in Cronkhite-Canada syndrome follows another independent sequence. PMID:11413916

    The Norwegian Continental Shelf can be subdivided into 3 different petroleum provinces: (1) the North Sea, (2) the Norwegian Sea including the Jan Mayen ridge, and (3) the Barents Sea including the islands of Svalbard. The majority of the fields and discoveries and most of the resources are located in the mature North Sea Basin. Significant resources are however also discovered in the Norwegian Sea and the Barents Sea. 39 fields are in production or decided to be developed while 3 fields are closed down. Approximately 70% of the discovered resources are located in these fields, of which some are gigantic in size (Statfjord, Ekofisk, Gullfaks, Oseberg, Troll and Snorre). Most of the remaining discoveries (134) are smaller in size and approximately 2/3 of the resources are gas. According to a recent study carried out by the Norwegian Petroleum Directorate the expected undiscovered Norwegian Petroleum Resources are assessed to be on the order of 3,5 billion Sm{sup 3} o.e. with a level of uncertainty ranging from 2 to 6 billion Sm{sup 3} o.e. 40% of the undiscovered petroleum resources are expected to be found as oil. These are the perspectives of the Norwegian Petroleum Resources. The resources of the Barents Sea is included in this perspective. The significance of the Barents Sea resources is not particularly important in the short-medium term perspective, but will be important in the longer perspective.

    Background Provider recommendation is a predictor of colorectal cancer (CRC) screening. Purpose To compare the effects of two clinic-based interventions on patient–provider discussions about CRC screening. Design Two-group RCT with data collected at baseline and 1 week post-intervention. Participants/setting African-American patients that were non-adherent to CRC screening recommendations (n=693) with a primary care visit between 2008 and 2010 in one of 11 urban primary care clinics. Intervention Participants received either a computer-delivered tailored CRC screening intervention or a nontailored informational brochure about CRC screening immediately prior to their primary care visit. Main outcome measures Between-group differences in odds of having had a CRC screening discussion about a colon test, with and without adjusting for demographic, clinic, health literacy, health belief, and social support variables, were examined as predictors of a CRC screening discussion using logistic regression. Intervention effects on CRC screening test order by PCPs were examined using logistic regression. Analyses were conducted in 2011 and 2012. Results Compared to the brochure group, a greater proportions of those in the computer-delivered tailored intervention group reported having had a discussion with their provider about CRC screening (63% vs 48%, OR=1.81, p<0.001). Predictors of a discussion about CRC screening included computer group participation, younger age, reason for visit, being unmarried, colonoscopy self-efficacy, and family member/friend recommendation (all p-values <0.05). Conclusions The computer-delivered tailored intervention was more effective than a nontailored brochure at stimulating patient–provider discussions about CRC screening. Those who received the computer-delivered intervention also were more likely to have a CRC screening test (fecal occult blood test or colonoscopy) ordered by their PCP.

    A case-control study was conducted to identify ewe characteristics that affect the risk of a ewe losing at least one lamb during the first 5 days post lambing. Data were from a national sheep registry, and only ewes that lambed in the spring of 2010 belonging to flocks that reported disease events were included. Ewes registered with abortion or stillbirth were excluded. Cases (n=4850) and controls (n=85,354) from 1153 flocks were studied using logistic regression models, accounting for within flock correlation. The odds of losing at least one lamb increased substantially when litter size exceeded two. For example, in 3-year-old ewes, the odds were 6 times greater for those with 3 lambs than for those with 1 lamb. However, the effect of litter size depended on the age of the ewe; for example for ewes giving birth to triplet lambs, the odds of losing at least one lamb were 2.7 times greater in 1-year-old ewes than in 3-year-old ewes. Dystocia was associated with increased risk of losing at least one lamb, but the effect varied by litter size. In ewes with single lambs, the odds of lamb loss were 5 times greater in those that experienced dystocia than in those that did not, while within subgroups of ewes with twins, triplets or >3 lambs, the corresponding odds ratio (OR) of losing one or more lambs was 2.2, 1.5 and 1.3, respectively. Compared with ewes of the Norwegian White breed, ewes of old Norwegian breeds were less likely to lose lambs (OR=0.8). We also examined the effects of several diseases experienced by the ewe during pregnancy or shortly postpartum on the risk of subsequent neonatal lamb loss. Significantly increased risk was found for ewes with abdominal hernia (OR=2.5) and for ewes treated for moderate to severe clinical mastitis (OR=1.6) when compared with ewes without these disorders. In conclusion, our large study population allowed for a detailed analysis of the combined effect of important ewe factors that affected survival of their lambs in the

    The development of human neoplasms can be provoked by exposure to one of several viruses. Burkitt lymphoma, cervical carcinoma, and hepatocellular carcinoma are associated with Epstein-Barr, human papilloma, and hepatitis B virus infections, respectively. Over the past three decades, many studies have attempted to establish an association between colorectal cancer and viruses, with debatable results. The aim of the present research was to assess the presence of BK polyomavirus (BKV) DNA and protein in colorectal cancer samples from patients in the Western Province of Saudi Arabia. DNA extracted from archival samples of colorectal cancer tissues was analyzed for BKV sequences using polymerase chain reaction (PCR)-based techniques. In addition, expression of a BKV protein was assessed using immunohistochemical staining. None of the tumor and control samples examined tested positive for BKV DNA in PCR assays. Furthermore, immunohistochemical staining failed to detect viral proteins in both cancer and control specimens. These results may indicate that BKV is not associated with the development of colorectal adenocarcinoma in patients in the Western Province of Saudi Arabia. PMID:27173319

    Colorectal cancer is the third most common cancer in men and the second most common cancer in women worldwide. Diagnosing colorectal has been increasingly successful due to advances in technology. Flexible endoscopy is considered to be an effective method for early diagnosis and treatment of gastrointestinal cancer, making it a popular choice for screening programs. However, millions of people who may benefit from endoscopic colorectal cancer screening fail to have the procedure performed. Main reasons include psychological barriers due to the indignity of the procedure, fear of procedure related pain, bowel preparation discomfort, and potential need for sedation. Therefore, an urgent need for new technologies addressing these issues clearly exists. In this review, we discuss a set of advanced endoscopic technologies for colorectal cancer screening that are either already available or close to clinical trial. In particular, we focus on visual-inspection-only advanced flexible colonoscopes, interventional colonoscopes with alternative propulsion mechanisms, wireless capsule colonoscopy, and technologies for intraprocedural bowel cleansing. Many of these devices have the potential to reduce exam related patient discomfort, obviate the need for sedation, increase diagnostic yield, reduce learning curves, improve access to screening, and possibly avert the need for a bowel preparation.

    Type and intensity of tumor-infiltrating lymphocytes (TILs) in close proximity to the primary tumor are prognostically significant in postoperative patients. High intensity of TILs is considered to be a prognostically beneficial factor. The research included 66 postoperative colorectal cancer patients. The control group comprised 20 colon segments. Monoclonal antibodies LCA, CD3, CD4, CD5, CD8, CD20, CD23 and CD138 were used to differentiate between T and B lymphocytes. Types of cells in the infiltrate were defined. We found greater numbers of T and B lymphocytes located in close proximity to the cancerous tissue when compared to the control group. T lymphocyte intensity in the inflammatory infiltrations was directly correlated with the size of resected tumors, presence of regional lymphatic node metastases and histological grade of malignancy. Lymphocytic infiltrations of greater intensity located in close proximity to the primary tumor were found in subjects with less advanced colorectal cancer. The research presented here proves direct dependence between the immune system and colorectal cancer. The presence of lymphocytes in the inflammatory infiltrations located in close proximity to the cancerous tissue has been proved to be prognostically beneficial. The obtained results support the application of immunotherapy in colorectal cancer treatment. PMID:27543872

    Knowledge of the extent of primary colorectal carcinoma at initial diagnosis is critical for proper management of disease. Currently, CT does not have a role in screening for colorectal carcinoma, though promising work on virtual colonoscopy is on the horizon. In patients with proven colorectal carcinoma, accurate prospective noninvasive assessment can identify those who may benefit from preoperative local radiotherapy, hepatic resection or cryoablation, or intra-arterial chemotherapy. CT should be considered complementary to the clinical assessment of colorectal carcinoma and to other modalities, such as barium enema, endorectal ultrasonography, MRI, and immunoscintigraphy. Although limited in evaluation of the primary tumor and local spread, CT has proven useful in assessing patients thought to harbor extensive local or metastatic disease. CT is generally the modality of choice for imaging the postoperative patient. The cross-sectional display of CT clearly depicts the operative bed, particularly after abdominoperineal resection. Baseline examinations should be obtained 2 to 4 months after surgery, with follow-up examinations every 6 to 9 months for 2 years, and yearly studies thereafter. CT-guided biopsies should be performed when findings suggest recurrent carcinoma. PMID:8848730

    Background Colorectal cancer is a commonly diagnosed cancer and the cause of many cancer deaths worldwide. Nutrients might be crucial in the pathogenesis and development of colorectal cancer. Although a number of studies have demonstrated the potential effects of nutrients, many challenges still remain Summary A tremendous amount of research has emerged concerning the roles of nutrients in colorectal cancer during the past decades. Here, we review the latest research progress on nutrients, including vitamins, folic acid, calcium, selenium and dietary fiber, involved in colorectal cancer prevention Key Message Nutrients are commonly consumed in foods or dietary supplements. It is clear that nutrients could play an important role and influence colorectal cancer outcomes. The relationship between nutrients and colorectal risk is complex. Vitamins, folic acid, calcium, selenium and dietary fiber have been proposed as potential agents to prevent colorectal cancer. However, some studies found that these nutrients did not reduce the incidence of colorectal cancer Practical Implications The supplementary dose of nutrients, the length of time required to observe the effects and confounding factors during the study might influence the role of nutrients in the prevention of colorectal cancer. Therefore, more evidence from ongoing clinical trials with different population groups and longer follow-up periods is critical to determine the relationship between nutrients and colorectal cancer.

    Background Colorectal cancer is the third commonest cancer and the third leading cause of cancer death among men and women. It has been proposed that dietary factors are responsible for 70-90% of colorectal cancer and diet optimization may prevent most cases. Aim To evaluate the role of dietary components and supplements in colorectal cancer. Methods Bibliographical searches were performed in Pubmed for the terms “diet and colorectal cancer”, “diet and colon cancer”, “diet and rectal cancer”, “nutrition and colorectal cancer”, “probiotics and colorectal cancer”, “prebiotics and colorectal cancer”, “alcohol and cancer” and “colorectal cancer epidemiology”. Results Consumption of processed or red meat, especially when cooked at high temperatures may be associated with increased risk of colorectal cancer. The evidence for dietary fibre is unclear but foods that contain high amounts of fibre are usually rich in polyphenols which have been shown to alter molecular processes that can encourage colorectal carcinogenesis. Meta-analyses provide evidence on the benefits of circulating, diet-derived and supplemented, vitamin D and Calcium. We also found that diets rich in Folate may prevent colorectal carcinoma. The evidence on dietary micronutrients such as Zinc and Selenium in association with colorectal cancer is not conclusive. It has been suggested that there may be a direct association between alcohol intake and colorectal cancer. In vitro and in vivo studies have highlighted a possible protective role of prebiotics and probiotics. Conclusions The lack of randomized trials and the presence of confounding factors including smoking, physical activity, obesity and diabetes may often yield inconclusive results. Carefully designed randomized trials are recommended. PMID:24294513

    In order to determine the occurrence, distribution, and significance of mold species in groundwater- and surface water-derived drinking water in Norway, molds isolated from 273 water samples were identified. Samples of raw water, treated water, and water from private homes and hospital installations were analyzed by incubation of 100-ml membrane-filtered samples on dichloran-18% glycerol agar. The total count (number of CFU per 100 ml) of fungal species and the species diversity within each sample were determined. The identification of mold species was based on morphological and molecular methods. In total, 94 mold species belonging to 30 genera were identified. The mycobiota was dominated by species of Penicillium, Trichoderma, and Aspergillus, with some of them occurring throughout the drinking water system. Several of the same species as isolated from water may have the potential to cause allergic reactions or disease in humans. Other species are common contaminants of food and beverages, and some may cause unwanted changes in the taste or smell of water. The present results indicate that the mycobiota of water should be considered when the microbiological safety and quality of drinking water are assessed. In fact, molds in drinking water should possibly be included in the Norwegian water supply and drinking water regulations. PMID:17028226

  20. Social Variations in Perceived Parenting Styles among Norwegian Adolescents.

    Previous research has documented the associations between parenting and parenting styles and child and adolescent outcomes. Little is known, however, about the social structuring of parenting in contemporary Nordic welfare states. A possible hypothesis is that socioeconomic variations in parenting styles in present-day Norway will be small because of material affluence, limited income inequality, and an active welfare state. This study examines social variations in parenting as perceived by Norwegian adolescents (N = 1362), with a focus on four parenting style dimensions: responsiveness, demandingness, neglecting, and intrusive. Responsiveness seems to capture major divisions in parenting. Adolescents in families with fewer economic resources experienced their parents as somewhat less responsive, but responsiveness was not related to parents' education. Low parental education was on the other hand associated with perceptions of parents as neglecting and intrusive. Viewing parents as demanding did neither vary with parental education nor with family economy. Substantial variations in parenting styles persist in present-day Norway, and these variations correspond moderately with the families' placement in the social structure. Indicators of parenting and parenting styles may be useful indicators of some aspects of child and adolescent well-being. PMID:25132873

    Water ingress represents one of the main challenges in subsea tunnelling, particularly when this occurs in sections with poor rock mass quality. This paper is discussing the main characteristics of water ingress in subsea hard rock tunnels based on the experience from almost 50 such tunnels that have been built in Norway. Following a brief description of the geological conditions and the basic design of the subsea tunnels, pre-construction investigations and investigations during excavation are discussed with particular emphasis on prediction of water ingress. Two cases with particularly difficult conditions; the Bjorøy tunnel and the Atlantic Ocean tunnel, are discussed in detail. In these cases, large water inflow with pressure of up to 2.4 MPa was encountered at major faults/weakness zones during excavation, and special procedures were required to cope with the problems. Based on the experience from the Norwegian projects, it is concluded that continuous follow-up by experienced engineering geologists, probe drilling with the drilling jumbo and pre-grouting where required are the most important factors for coping with water ingress and ensuring stability.

    The purpose was to examine musculoskeletal disorders in Norwegian female biathlon athletes (age ≥ 16), both juniors and seniors. The design was a retrospective cross-sectional study. In all, 148 athletes (79.1%) responded; of these, 118 athletes were 16–21 years (juniors) (77.6%), and 30 athletes were 22 years or older (seniors) (20.3%), and mean age was 19.1. A validated questionnaire was used to collect the data. The prevalence of musculoskeletal disorders was 57.8%. The most affected parts were the knee (23.0% of the total injuries), calf (12.2%), ankle/foot (10.8%), lower back (10.8%), and thigh (10.1%). The disorders resulted in training/competition cessation for 73.5% of athletes, in alternative training for 87.8%. Fifty percent of the athletes had one or several musculoskeletal disorders. Most of the problems occurred preseason, and the duration of symptoms was often prolonged. Few differences between the juniors and seniors were found. This study showed the prevalence of musculoskeletal problems among female biathlon athletes. The results indicate that prevention of lower limb problems must be prioritized, especially during the preseason. PMID:24379711

    The Norwegian-Danish basin (NDB) extends from offshore Norway southeast through Denmark. This study, initiated by the Danish Energy Agency to evaluate hydrocarbon potential, consists of geophysical structural and stratigraphic mapping combined with geologic source rock and reservoir analysis. Approximately 25 wells and 15,000 km of seismic data were included. Formation of the NDB resulted from uplift of the Variscan foldbelt followed by subsidence of the foreland, i.e., the NDB and the North German basin. The Ringkoebing-Fyn High, a positive feature probably established in the late Precambrian and persisting to present, separates the basins, thus constituting the southern boundary of the NDB. Northeast the basin is bounded by the Fennoscandian shield and to the west by the North Sea graben system. Following deposition of Rotliegendes eolian and fluviatile sandstones, a major Late Permian marine transgression deposited up to 2000 m of evaporites and carbonates. Early Triassic regression resulted in thick red-bed deposits. Halokinesis commencing in the Upper Triassic dominated subsequent structural development. Continued subsidence led to deposition of Early Jurassic shelf mudstones overlain by deltaic sandstones. Rising seas during Late Cretaceous allowed widespread deposition of oceanic pelagic chalk. Early Paleocene wrench movements produced inversion. Basinal downwarping during the Tertiary was accompanied by progradation from the northeast. The complex tectonic history provides numerous different structural styles and a variety of depositional environments. To date only obvious structural features have been tested. This integrated basin study demonstrates that a number of other hydrocarbon plays remain to be explored.

    Results of measurements of the whole-body contents of /sup 137/Cs during the period 1965-1983 in Lapps from the Kautokeino area in Norway are reported with measurements of /sup 137/Cs in reindeer meat during the period 1966-1983. By using available data on /sup 137/Cs in precipitation for the period 1950-1980, transfer coefficients from /sup 137/Cs in precipitation to reindeer meat have been assessed. A correlation between the /sup 137/Cs content in reindeer meat and the /sup 137/Cs content in Lapp reindeer breeders has been established. The average whole-body committed dose equivalent, H50, to the reindeer breeders from internally deposited /sup 137/Cs from intakes up to year 2000 was assessed to 13 mSv with a peak value of 30 mSv. In comparison, the corresponding committed dose equivalent to the Norwegian population from internally deposited /sup 137/Cs has been estimated to be about 1 mSv. The higher intake of /sup 137/Cs by reindeer breeders is due to the lichen-reindeer-man exposure pathway.

    The aim was to test the construct validity of the Nurse Competence Scale. The Nurse Competence Scale has been used in hospital settings for various purposes in several countries. Despite this, confirmatory factor analyses are scarcely reported. The present study is based on re-analyses of data from 2007 (i.e. psychometric testing) and 593 newly graduated nurses working in various contexts were included. Confirmatory as well as exploratory factor analyses (Principal Component Analysis) were carried out. The original 7-factor model of the Nurse Competence Scale (73 items) was not confirmed. The exploratory factor analyses resulted in a Norwegian Nurse Competence Scale consisting of 46 items in the following competence categories: Planning and delivery of care, Teaching functions, Professional leadership, Research utilization and nursing values and Professional awareness. The results underline the needs for psychometric testing of an instrument after translation processes. The instrument is suitable for describing and comparing nurse competence for various reasons. It may also be helpful in creating competence development programs at an individual as well as at an organizational level. Further studies with a broader sample are recommended. PMID:25434831

    Background Low-income and racial/ethnic minority populations experience disproportionate colorectal cancer (CRC) burden and poorer survival. Novel behavioral strategies are needed to improve screening rates in these groups. Purpose To test a theoretically based “implementation intentions” intervention for improving CRC screening among unscreened adults in urban safety-net clinics. Design Randomized controlled trial. Setting/participants Adults (N=470) aged ≥50 years, due for CRC screening, from urban safety-net clinics were recruited. Intervention The intervention (conducted in 2009–2011) was delivered via touchscreen computers that tailored informational messages to decisional stage and screening barriers. The computer then randomized participants to generic health information on diet and exercise (Comparison group) or “implementation intentions” questions and planning (Experimental group) specific to the CRC screening test chosen (fecal immunochemical test or colonoscopy). Main outcome measures The primary study outcome was completion of CRC screening at 26 weeks based on test reports (analysis conducted in 2012–2013). Results The study population had a mean age of 57 years, and was 42% non-Hispanic African American, 28% non-Hispanic white, and 27% Hispanic. Those receiving the implementation intentions–based intervention had higher odds (AOR=1.83, 95% CI=1.23, 2.73) of completing CRC screening than the Comparison group. Those with higher self-efficacy for screening (AOR=1.57, 95% CI=1.03, 2.39), history of asthma (AOR=2.20, 95% CI=1.26, 3.84), no history of diabetes (AOR=1.86, 95% CI=1.21, 2.86), and reporting they had never heard that “cutting on cancer” makes it spread (AOR=1.78, 95% CI=1.16, 2.72) were more likely to complete CRC screening. Conclusions The results of this study suggest that programs incorporating an implementation intentions approach can contribute to successful completion of CRC screening even among very low-income and

    Objective To determine the quality of surgical management offered to patients with colorectal cancer (CRC) as measured by adequacy of nodal resections and compare variations across the major hospitals in Jamaica. Method Data was obtained from the CRC Registry of patients diagnosed and treated surgically for CRC during the 3-year period commencing January 1, 2011. Variables analyzed included tumor site, stage and number of lymph nodes resected across hospitals. Results During the period under review 60% (349) of 586 patients had resections and formed the basis of this study. Of these 49% were treated at the UHWI, 27% from the KPH and STH, 15% from CRH and MRH and 8% from a private laboratory (DPS). Patient distribution was similar at UHWI compared to the others with mean age (61 vs 62) and with slightly more women having surgery (53% Vs 54%) (UHWI vs Others). For tumor grade, margin status, lymphovascular and depth of invasion (majority T3) there was no difference between UHWI and the other sites, although a smaller percentage of tumors treated at UHWI had Crohn's like reaction (p = 0.01). There was a larger proportion of sigmoid cancer at UHWI while the reverse trend was seen in cancers of the rectum (p = 0.027). The tumors treated at UHWI have a larger median number of regional nodes when compared to the other facilities (14 vs 10; p < 0.001) and also more likely to have positive nodes, as were women and younger patients. Comparison across facilities revealed that the proportion of tumors classed as well differentiated, circumferential margin involvement, and having lymphovascular invasion were higher for specimens processed at the private facility (p = 0.021, 0.035, 0.01 respectively). Histopathology reports of tumors treated at UHWI and DPS had median 14 and 18 nodes respectively while at NPH laboratory and CRH they were 9 and 10 respectively (p < 0.001), whilst those of the ascending, descending, sigmoid colon and rectum had median 15, 11, 13, 11

    Colorectal cancer is emerging as one of the commonest cancers in Malaysia. Data on colorectal cancer from the National Cancer Registry is very limited. Comprehensive information on all aspects of colorectal cancer, including demographic details, pathology and treatment outcome are needed as the management of colorectal cancer has evolved rapidly over the years involving several disciplines including gastroenterology, surgery, radiology, pathology and oncology. This registry will be an important source of information that can help the development of guidelines to improve colorectal cancer care relevant to this country. The database will initially recruit all colorectal cancer cases from eight hospitals. The data will be stored on a customized web-based case report form. The database has begun collecting data from 1 October 2007 and will report on its first year findings at the end of 2008. PMID:19230248

    Adult colorectal epithelium undergoes continuous renewal and maintains homeostatic balance through regulated cellular proliferation, differentiation, and migration. The canonical Wnt signaling pathway involving the transcriptional co-activator β-catenin is important for colorectal development and normal epithelial maintenance, and deregulated Wnt/β-catenin signaling has been implicated in colorectal carcinogenesis. Colorectal carcinogenesis has been linked to radiation exposure, and radiation has been demonstrated to alter Wnt/β-catenin signaling, as well as the proteasomal pathway involved in the degradation of the signaling components and thus regulation of β-catenin. The current review discusses recent progresses in our understanding of colorectal carcinogenesis in relation to different types of radiation and roles that radiation quality plays in deregulating β-catenin and ubiquitin-proteasome pathway (UPP) for colorectal cancer initiation and progression.

    Colorectal cancer is a common cancer and the fourth leading cause of death in Korea. The incidence and mortality of colorectal cancer varies according to risk factors, such as age, family history, genetic history, food habits, and physical activities. Some studies have focused on the association between vitamin D and colorectal cancer. Today, there is growing evidence that high vitamin D intake and a plasma level of 25(OH)D(3) reduce the incidence of colorectal cancer by modifying cancer angiogenesis, cell apoptosis, differentiation, and proliferation. Taken together, these results suggest that vitamin D supplementation alone, or in combination with anti-cancer agents, might reduce the incidence of colorectal cancer. In this review, we discuss the function and mechanism of vitamin D including the effect of vitamin D on colorectal cancer. PMID:22007275
