RESUMO

BACKGROUND: Patient satisfaction or experience with colorectal cancer screening can determine adherence to screening programs. An evaluation of validated patient reported outcome measures (PROMs) for measuring experience or satisfaction with colorectal cancer screening does not exist. Our objective was to identify and critically appraise validated questionnaires for measuring patient satisfaction or experience with colorectal cancer screening. METHODS: We conducted a systematic review following the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. We conducted searches on MEDLINE, EMBASE, PsychINFO, CINAHL and BiblioPRO and assessed the methodological quality of studies and measurement properties of questionnaires according to the COSMIN guidelines for systematic reviews of PROMs. PROSPERO registration number: CRD42019118527. RESULTS: We included 80 studies that used 75 questionnaires, of which only 5 were validated. Four questionnaires measured satisfaction with endoscopy: two in the context of colorectal cancer screening (for colonoscopy and sigmoidoscopy) and two for non-screening endoscopy. One questionnaire measured satisfaction with bowel preparation. The methodological quality of studies was variable. The questionnaires with evidence for sufficient content validity and internal consistency were: the CSSQP questionnaire, which measures safety and satisfaction with screening colonoscopy, and the Post-Procedure questionnaire which measures satisfaction with non-screening endoscopic procedures. CONCLUSIONS: This systematic review shows that a minority of existing PROMs for measuring patient satisfaction with colorectal cancer screening are validated. We identified two questionnaires with high potential for further use (CSSQP and the Post-Procedure questionnaire).

RESUMO

OBJECTIVES: This study aimed to describe how colorectal practice guidelines (PGs) incorporate the patient perspective. STUDY DESIGN AND SETTING: We searched in the Guidelines International Network library, MEDLINE, National Guideline Clearinghouse, NHS Evidence database, and TRIP database. Two authors independently selected the PGs. We considered recommendations rated or worded as weak or conditional or suggesting multiple options, as potentially preference sensitive. Two authors independently evaluated if, in potentially sensitive recommendations, the patient perspective was incorporated. RESULTS: We included 28 PGs that contained 588 recommendations, being 256 potentially preference sensitive. Ten PGs (36%) included patients in the development process, and 12 (43%) provided information about patients' perspectives. Nine PGs (32%) included recommendations in which the patient perspective was explicitly considered, and 13 (46.4%) that recommended a discussion with the patient. From a total of 588 recommendations, 9.7% (25/256) of potentially preference-sensitive recommendations considered the patient perspective. The inclusion of patients in the development process was associated with a more frequent incorporation of the patient perspective in potentially preference sensitive recommendations (70% vs. 0%; P < 0.001). CONCLUSIONS: Guideline users should be aware that the incorporation of the patient perspective in colorectal cancer PGs is suboptimal. Guideline developers should make efforts to incorporate the patient perspective, especially in preference-sensitive recommendations.

RESUMO

The discovery of drugs that can be used for the treatment of allergic disease is important in human health. Arctium lappa Linne (Compositae) (AL) has been used as a traditional medicine in Brazil and throughout Asia and is known to have an anti-inflammatory effect. In this study, the inhibitory effects of AL on degranulation and the release of mediators as well as on inhibition of cys-leukotriene biosynthesis by basophils were investigated. AL was selected out of 10,000 herbal extracts in a set-up for high throughput screening in which the degree of degranulation was monitored by the release of beta-hexosaminidase from rat basophil leukemia (RBL-2H3) cells. The AL extract significantly reduced degranulation and biosynthesis of cys-leukotrienes of human basophils in peripheral blood mono-nuclear cells (PBMCs) (50% inhibitory concentration [IC(50)] = 8.3 and 11.4 microg/ml, respectively). Viability and metabolic activity of the PBMCs were not affected. Although arctiin, the active component of AL that has been described in the literature, was not able to reduce degranulation in RBL-2H3 cells, a single high-performance liquid chromatography (HPLC) fraction from the AL extract inhibited beta-hexosaminidase release (IC(50) = 22.2 microg/ml). Topical administration of an aqueous extract of AL (5 mg/ear) on the ear of whey-sensitized mice 4 hrs before challenge with whey in the ear inhibited acute ear swelling by 50% in an in vivo cow's milk allergic model. The extract had no effect in this model when administered orally. In conclusion, the active component present in the active HPLC fraction of the AL extract was able to significantly reduce the release of inflammatory mediators through inhibition of degranulation and cys-leukotriene release in vitro. In addition, this active component was able to inhibit acute skin response in mice in vivo, indicating that AL is a very promising natural component for use in anti-allergic treatment.

RESUMO

HIV and hepatis C virus (HCV) coinfection is frequently associated with rapid progression of HCV-related disease, resulting in a higher risk of cirrhosis. Data suggest that natural T cells expressing the Vdelta1 T cell receptor rearrangement are recruited in the liver of chronically HCV-infected patients and are increased in the peripheral blood of HIV-infected persons. We studied gammadelta T cell distribution in the peripheral blood and liver of HCV-infected and HIV/HCV-coinfected patients in the presence and absence of antiretroviral therapy. We observed that Vdelta1+ T cells releasing helper T cell type 1 cytokines are compartmentalized not only in the liver of HCV+ patients, but also of HIV/HCV-coinfected persons. HIV/HCV patients showed an increased frequency of both peripheral and intrahepatic Vdelta1 natural T lymphocytes, resulting in a higher degree of hepatic inflammation when compared with patients with other liver diseases. Finally, highly active antiretroviral therapy (HAART) was unable to restore Vdelta1T cell circulation to normal levels in chronically HIV-infected persons. We conclude that gammadelta T lymphocytes released from tissue to the bloodstream circulation under the influence of chronic HIV infection may contribute to intrahepatic Vdelta1 compartmentalization and progression of liver disease, independently of HAART.

RESUMO

The aim of this study was to characterize [3H]CGP 12177 (CGP) binding to beta-adrenergic receptors in isolated hepatocytes of the European eel (Anguilla anguilla), in which the involvement of cAMP in epinephrine-induced glucose release has been previously observed. Specific binding of CGP was saturable, reversible, and linear as a function of cell number. Analysis of binding data suggested a single class of binding sites, with a Kd of 1.31 nM and a number of approximately 7000 beta-adrenergic receptors per cell. The potency order of specific inhibition of [3H]CGP binding was CGP > propranolol > or = alprenolol >> butoxamine > or = atenolol, while phentolamine and prazosin failed to significantly displace the tracer at concentrations up to 100 microM. The binding kinetics of CGP were closely related to its biological effect. In fact, the drug dose-dependently counteracted the enhancement of intracellular cAMP levels induced by epinephrine in isolated hepatocytes with a Kd of 1.06 nM. Moreover, it antagonized the hormone-induced stimulation of adenylyl cyclase activity in hepatic membranes as well as of glucose release from cells. These data clearly show that beta-adrenergic receptors are coupled to the adenylyl cyclase/cAMP transduction pathway in eel liver.
