Comparison of the yield from two faecal immunochemical tests at identical cutoff concentrations – a randomized trial in Latvia
2016
OBJECTIVE We have compared the performance of two faecal immunochemical tests (FIT) in an average-risk population. MATERIALS AND METHODS Altogether, 10 000 individuals aged 50-74 were selected randomly from the population of Latvia in 2011 and assigned randomly either to OC-Sensor or to FOB Gold single-time testing. Positivity of the test, frequency of colonic lesions, number needed to screen (NNscreen) and scope for the detection of an advanced neoplasm (cancer and advanced adenoma) were compared between the tests using the same cutoff concentrations in µg/g faeces. Confidence intervals (CIs) at 95% were calculated. RESULTS Positivity with the cutoff set at 10 µg/g faeces was 12.8% (95% CI…
Intraprocedural bowel cleansing with the JetPrep cleansing system improves adenoma detection.
2014
AIM: To investigate the impact of JetPrep cleansing on adenoma detection rates. METHODS: In this prospective, randomized, crossover trial, patients were blindly randomized to an intervention arm or a control arm. In accordance with the risk profile for the development of colorectal carcinoma, the study participants were divided into high-risk and low-risk groups. Individuals with just one criterion (age > 70 years, adenoma in medical history, and first-degree relative with colorectal cancer) were regarded as high-risk patients. Bowel preparation was performed in a standardized manner one day before the procedure. Participants in the intervention arm underwent an initial colonoscopy with sta…
Clinical results of transanal endoscopic microsurgery
1988
Using the "transanal endoscopic microsurgery" technique, 140 patients were treated at the Department of Surgery in Cologne and Mainz. Of the patients with adenomas, 68.2% had typical symptoms preoperatively. The postoperative hospital attendance was 8.7 days, with an average resection size of 14.4 cm2. The postoperative complication rate was 5%, and there were no deaths related to the technique. In a prospective controlled trial, 2.2% of the patients with adenomas treated endoscopically in Mainz showed recidivation, requiring reoperation. The follow-up rate was 100%. In 30 cases, microscopic examination revealed carcinoma. Radical reoperation in 8 pT1 tumours showed neither remaining tumour…
Chromoendoscopy in Inflammatory Bowel Disease
2012
Chromoendoscopy with methylene blue or indigo carmine significantly increases the diagnostic yield of finding intraepithelial neoplasia in patients with longstanding colitis. The number needed to treat is 14 for panchromoendoscopy to identify 1 additional patient with dysplasia. Chromoendoscopy can greatly facilitate the identification of flat lesions harboring intraepithelial neoplasia. Chromoendoscopy can guide biopsies and clearly reduces the amount of biopsies that are needed per patient. Magnifying endoscopy or CLE are additional techniques, which can be used in conjunction with chromoendoscopy to further reduce the amount of biopsies and to further increase the diagnostic yield. Chrom…
Relation between health literacy, self-care and adherence to treatment with oral anticoagulants in adults: a narrative systematic review
2018
Background Oral anticoagulants (OAC) are widely used in patients with cardiovascular diseases. However, for optimal OAC self-care patients must have skills, among which health literacy (HL) is highlighted. We aimed to describe the relation between HL and self-care in cardiovascular patients on OAC treatment. Methods Electronic searches were carried out in the PubMed, Scopus, Embase, CINAHL, Web of Science, Cochrane Library, SciELO, IME-Biomedicina, CUIDEN Plus and LILACS databases, limited to Spanish and English language and between January 2000–December 2016. Papers reported on adults older than 18 years, taking OAC by themselves for at least three months. PRISMA guidelines were used for p…
Tiesnešu atsevišķās domas kā tiesību palīgavots. Augstākās tiesas Administratīvo lietu departamenta pieredze (2014.-2017.)
2018
Bakalaura darba tēmas nosaukums ir „Tiesnešu atsevišķās domas kā tiesību palīgavots. Augstākās tiesas Administratīvo lietu departamenta pieredze (2014.-2017.) ”. Tā kā tiesnešu atsevišķās domas nav bieži sastopamas, šī darba mērķis ir noskaidrot kādu ietekmi sniedz tiesneša atsevišķo domu institūts. Lai to noskaidrotu, darba autore analizē tiesību zinātnieku dažādos viedokļus par tiesnešu atsevišķo domu institūta esību. Autore klasificē tiesneša atsevišķo domu iedalījuma kritērijus un aplūko tiesnesim piešķirtās brīvības, vārda brīvību un neatkarību, tiesneša atsevišķo domu izpratnē. Salīdzinošā nolūkā tiek apskatīts ne tikai Latvijas, bet arī citu valstu normatīvais regulējums. Darba autor…
Celiac disease and selective immunoglobulin A deficiency
1997
Selective IgA deficiency was observed in 12 of 688 (1.7%) patients with celiac disease who were clinically undistinguishable from patients with celiac disease with normal IgA levels. This high prevalence of IgA deficiency in patients with celiac disease makes serum IgA assay advisable when screening for celiac disease is performed by measurement of antigliadin antibodies or anti-IgA endomysium antibodies. Similarly, subjects with IgA deficiency should be considered at risk of celiac disease.
Multiple nevoid spiradenomas.
1994
This report delineates a new clinical presentation of multiple benign spiradenoma (BS), a diffuse linear nevoid pattern. A 16-year-old girl, in otherwise good health, had many papulonodular lesions, varying in color from blue-gray to bright red, disposed linearly on the right half of her body, involving the periorbital region, cheek, lateral side of the neck, trunk, linea alba, right thigh, and leg. Only a few nodules were slightly painful. Lesions were reported to be present at birth; no family members had similar lesions, either in solitary or multiple form. Excisional biopsies of three lesions from the neck, abdomen, and leg, respectively, were performed; histologically, all three sample…
Cytomegalovirus Misleads Its Host by Priming of CD8 T Cells Specific for an Epitope Not Presented in Infected Tissues
2003
Cytomegaloviruses (CMVs) code for several proteins that inhibit the presentation of antigenic peptides to CD8 T cells. Although the molecular mechanisms of CMV interference with the major histocompatibility complex class I pathway are long understood, surprisingly little evidence exists to support a role in vivo. Here we document the first example of the presentation of an antigenic peptide being blocked by a CMV immune evasion protein in organs relevant to CMV disease. Although this Db-restricted peptide, which is derived from the antiapoptotic protein M45 of murine CMV (mCMV), is classified as an immunodominant peptide based on response magnitude and long-term memory, adoptive transfer of…
Subdominant CD8 T-Cell Epitopes Account for Protection against Cytomegalovirus Independent of Immunodomination▿ †
2008
ABSTRACTCytomegalovirus (CMV) infection continues to be a complication in recipients of hematopoietic stem cell transplantation (HSCT). Preexisting donor immunity is recognized as a favorable prognostic factor for the reconstitution of protective antiviral immunity mediated primarily by CD8 T cells. Furthermore, adoptive transfer of CMV-specific memory CD8 T (CD8-TM) cells is a therapeutic option for preventing CMV disease in HSCT recipients. Given the different CMV infection histories of donor and recipient, a problem may arise from an antigenic mismatch between the CMV variant that has primed donor immunity and the CMV variant acquired by the recipient. Here, we have used the BALB/c mouse…
