In this study, we evaluate the role of information anxiety and information load on the intention to read information from prescription drug information leaflets (PILs). These PILs were developed based on the principals of information load and consumer information processing. This was an experimental prospective repeated measures study conducted in the United States where 360 (62% response rate) university students (>18 years old) participated. Participants were presented with a scenario followed by exposure to the three drug product information sources used to operationalize information load. The three sources were: (i) current practice; (ii) pre-existing one-page text only; and (iii) interventional one-page prototype PILs designed for the study. Information anxiety was measured as anxiety experienced by the individual when encountering information. The outcome variable of intention to read PILs was defined as the likelihood that the patient will read the information provided in the leaflets. A survey questionnaire was used to capture the data and the objectives were analyzed by performing a repeated measures MANOVA using SAS version 9.3. When compared to current practice and one-page text only leaflets, one-page PILs had significantly lower scores on information anxiety ( p information load ( p Information anxiety and information load significantly impacted intention to read ( p < 0.001). Newly developed PILs increased patient's intention to read and can help in improving the counseling services provided by pharmacists.

Providing patients with specific information about their own drugs can reduce unintentional misuse and improve compliance. Searching for information is time-consuming when information is not personalized and is written using medical vocabulary that is difficult for patients to understand. In this study we explored patient information needs regarding visualizing of drug information and interrelationships by conducting a total of four co-design workshops with patients, other users and pharmacists. We developed a prototype and drug ontology to support reasoning about drug interactions. We evaluated individual performance in finding information, understanding the drug interactions, and learning from the provided information in the prototype compared to using patient information leaflets (PILs). We concluded that interactive visualization of drug information helps individuals find information about drugs, their side effects and interactions more quickly and correctly compared to using PILs. Our study is limited to co-morbid patients with transient ischaemic attack with several chronic diseases.

The purpose of patient information leaflets (PILs) is to inform patients about the administration, precautions and potential side effects of their prescribed medication. Despite European Commission guidelines aiming at increasing readability and comprehension of PILs little is known about the potential risk information has on patients. This article explores patients' reactions and subsequent behavior towards risk information conveyed in PILs of commonly prescribed drugs by general practitioners (GPs) for the treatment of Type 2 diabetes, hypertension or hypercholesterolemia; the most frequent cause for consultations in family practices in Germany. We conducted six focus groups comprising 35 patients which were recruited in GP practices. Transcripts were read and coded for themes; categories were created by abstracting data and further refined into a coding framework. Three interrelated categories are presented: (i) The vast amount of side effects and drug interactions commonly described in PILs provoke various emotional reactions in patients which (ii) lead to specific patient behavior of which (iii) consulting the GP for assistance is among the most common. Findings show that current description of potential risk information caused feelings of fear and anxiety in the reader resulting in undesirable behavioral reactions. Future PILs need to convey potential risk information in a language that is less frightening while retaining the information content required to make informed decisions about the prescribed medication. Thus, during the production process greater emphasis needs to be placed on testing the degree of emotional arousal provoked in patients when reading risk information to allow them to undertake a benefit-risk-assessment of their medication that is based on rational rather than emotional (fearful) reactions.

Young, Amber; Tordoff, June; Smith, Alesha

2017-11-01

Medicines information leaflets can equip patients to be in control of their own healthcare and support the safe and effective use of medicines. The design and content of leaflets influences patients' willingness to read them, and poor examples can cause patient confusion and anxiety. Researchers examined the literature over the past 8 years to determine the content and design of medicine information leaflets that patients prefer in order to read, understand, and use them effectively. It was found that existing leaflets do not meet patients' needs and appear ineffective. Leaflets lack the information patients seek and may contain non-essential material, affecting patients' perception of, and willingness to read them. Additionally, the acceptable leaflet length varies between patients. Application of good design principles improves readability, comprehension, and ability to locate information. Medicine information leaflets must meet patients' needs and be well designed. Tailoring information leaflets to patient characteristics and requirements would enhance effectiveness. Passive provision of pre-printed leaflets is outdated, unvalued and ineffective. Using automated computer systems for leaflet tailoring with the ability to further adapt patients' information might be the best way forward. Copyright © 2016 Elsevier Inc. All rights reserved.

The preoperative anxiety state is mainly caused by the fear of the circumstances surrounding the intervention. Anxiety causes increased postoperative pain, and a prolonged length of stay in hospital, which directly affect the cost of care. To evaluate the effects of providing an anaesthesia information leaflet on postoperative anxiety and pain in patients undergoing urological surgery in the Miguel Servet Hospital. A prospective quasi-experimental study of 100 cases, 51 of whom made up the intervention group who received the information leaflet, with the remaining 49 cases being in the control group. The Hospital Anxiety and Depression Scale and the visual analogue scale for pain were assessed in both groups, before and after surgery. Of the 100 patients, 72% were male and 28% female, with an average age of 67.3 years (standard deviation, 9.7). In the intervention group, 21.6% showed anxiety before surgery and 0% in the postoperative period. In the control group 30.6% presented anxiety during the preoperative period and 4% in the postoperative period (χ(2) Pearson 5.20, P=.023). The study showed a direct relationship between preoperative anxiety and postoperative pain (χ(2) Pearson 10.519, P=.001). Good information about the surgical process reduces anxiety levels in the postoperative period. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Printed education materials are often used to augment healthcare professional's verbal information to consumers so it serves as an important component of symptom management. They also enhance the teaching process and can be used by consumers as a home reference. This study was aimed to interpret consumers' perception on Consumer Medical Information Leaflets (CMILs) on obesity and lipid lowering drugs, on design and layout using the standard method such as Baker Able Leaflet Design (BALD). Convenience sampling was done. The study was conducted over a period of 3 years in community pharmacy settings in Tamil Nadu, India. The Consumer Medical Information Leaflets (CMILs) were randomly collected from different community pharmacies. Total of 19 CMILs which are commonly used by the consumers were collected and CMILs were assessed using BALD assessment tool Results: According to BALD assessment (46.28%) leaflets were rated as 'above standard' and (53.72) leaflets were rated as 'standard or poor' in layout and design since their scores were less than 25. This shows that this issue may be important from the patient's perspective, which may discourage patient from actually reading the CMILs. In India, generally CMILs are continued to be prepared in English and with higher proportion of consumers with English illiteracy. CMILs, which are prepared without taking consideration of reading level of consumers and proper layout and design, may not achieve the intended purpose. This is an important aspect that any company has to reckon while preparing leaflets and at least in some major local languages in which CMILs have to be prepared.

Background Patient information leaflets (PILs) are widely utilised within publically funded sexual health clinics to deliver sexual health-related information (SHRI); however, their continued value to clients in the era of social media is unclear. This study aimed to evaluate clients' opinions on three newly developed PILs and examine client views on other forms of SHRI delivery. An anonymous self-administered questionnaire was completed by clients attending the Western Sydney Sexual Health Centre (WSSHC) in 2012. High-risk population (HRP) vs non-high-risk population (non-HRP) views on PILs vs alternative methods of SHRI delivery were analysed by using Mann-Whitney U, Wilcoxon, McNemar and χ(2) tests. Over half (210/315; (67%)) of the consecutive clients from a culturally diverse population completed the survey. Sex workers (SW) and young people (YP) were significantly likely to have a high school education than non-HRP (PInformation Link (SHIL), a state-wide website and telephone line, were ranked significantly higher as a means of SHRI delivery on a Likert scale than newer technologies including Facebook (P<0.001), email (P<0.001), mobile phone applications (P<0.001), TVs in waiting rooms (P<0.001) and business cards (P<0.001). There was no significant difference in opinion between HRP and non-HRP. This study provides evidence for the ongoing use of PILs to deliver SHRI to clinic attendees, in conjunction with other forms of SHRI delivery such as websites and SHIL. Novel methods may require additional consumer engagement and a greater understanding of specific population's needs.

1994-10-08

Providing 75% of family planning services in the United Kingdom, general practitioners are required to produce leaflets which describe the contraceptive services they provide. The authors analyzed information about family planning provided to clients through practice leaflets. 88% of practice leaflets from the 198 practices in Devon were available from the Devon Family Health Services Authority for analysis. It was determined that the leaflets are not being best used to advertise the range and potential of family planning services. Although all practices in Devon offer contraceptive services, only 90% of leaflets mentioned that the services are available. Reference to postcoital contraception and information about services outside the practice for people who might not want to see their family doctor are also sorely lacking. A clear need exists to provide patients with more information. Finally, the authors found that group practices and those with female partners are most likely to give high priority to family planning issues in their leaflets.

McClinchy, Jane; Dickinson, Angela; Barron, Duncan; Thomas, Hilary

2011-12-01

In primary care, leaflets are often used to communicate health information. Increasingly, primary healthcare practitioners need to provide dietary advice. There is limited research exploring how nutrition information leaflets are used in primary care. The present study explored practitioner and lay experiences with respect to providing and receiving nutrition information in primary care, focusing in particular on the use of leaflets for nutrition information. A qualitative design was used incorporating focus groups with 57 practitioners based at seven general practitioner practices and a purposive sample of 30 lay participants attending six Consumer Health Organisations within one primary care trust. Focus groups were taped and transcribed verbatim and data were analysed thematically, assisted by computer software n6® (QSR International Pty Ltd, Melbourne, Australia). Practitioners discussed barriers to giving nutritional advice, access to leaflets, lay receptiveness to advice and their perceptions about the value of leaflets to lay people. Food was not considered in terms of its nutritional components by lay participants and the need for nutritional information was not perceived to be relevant until they had received a medical diagnosis. Lay participants discussed the importance of receiving nutritional advice relating to their medical diagnosis and the altered status of written information that was delivered personally. Practitioner and lay groups suggested improvements to ensure that nutritional advice be supported by relevant and appropriate written information. This research has underlined the continuing importance of nutrition information leaflets and concludes that there is particular value in involving lay participants in the development of nutrition information leaflets. © 2011 The Authors.

The aim of the study was to determine whether the introduction of a paediatric anaesthesia comic information leaflet reduced preoperative anxiety levels of children undergoing major surgery. Secondary objectives were to determine whether the level of understanding of participants and other risk factors influence STAIC-S (State-Trait Anxiety Inventory for Children-State subscale) score in children. We performed a randomized controlled parallel-group trial comparing preoperative anxiety between two groups of children aged >6 and comic information leaflet at home in addition to routine information given by the anaesthetist at least 1 day before surgery. The control group received the routine information only. The outcome measure was the difference between STAIC-S scores measured before any intervention and after the anaesthetist's visit. A multiple regression analysis was performed to explore the influence of the level of education, the anxiety of parents, and the childrens' intelligence quotient on STAIC-S scores. One hundred and fifteen children were randomized between April 2009 and April 2013. An intention-to-treat analysis on data from 111 patients showed a significant reduction (P=0.002) in STAIC-S in the intervention group (n=54, mean=-2.2) compared with the control group (n=57, mean=0.90). The multiple regression analysis did not show any influence on STAIC-S scores of the level of education, parental anxiety, or the intelligence quotient of the children. A paediatric anaesthesia comic information leaflet was a cheap and effective means of reducing preoperative anxiety, measured by STAIC-S, in children. NCT 00841022. © The Author 2016.

Leaflet escape of prosthetic valve is rare but potentially life threatening. It is essential to make timely diagnosis in order to avoid mortality. Transesophageal echocardiography and cinefluoroscopy is usually diagnostic and the location of the missing leaflet can be identified by computed tomography (CT). Emergent surgical correction is mandatory. We report a case of fractured escape of Edward-Duromedics mitral valve 27 years after the surgery. The patient presented with symptoms of acute decompensated heart failure and cardiogenic shock. She was instantly intubated and mechanically ventilated. After prompt evaluation including transthoracic echocardiography and CT, the escape of the leaflet was confirmed. The patient underwent emergent surgery for replacement of the damaged prosthetic valves immediately. Eleven days after the surgery, the dislodged leaflet in iliac artery was removed safely and the patient recovered well. PMID:23837121

Patients in need of medicine information.

Reliable medicine information is important not only for physicians and pharmacists, but also for patients [6]. However, the results of studies implemented in some countries show that patients may have slightly different needs and preferences in using sources of information [1, 4, 5, 7]. The main objective of patient medicines information is assisting consumers to achieve safe and effective use of pharmaceuticals [2, 3]. To identify patients' needs in medicine information and sources they use to receive it. We interviewed 1059 people who had visited community pharmacies in 10 regions of Armenia and Yerevan. Previously developed questionnaire was used for interviewing patients. Statistical analysis was conducted using SPSS program. We found that consumers need medicine information. 68.9% of respondents often use pharmaceuticals only if necessary medicines information is available. The majority of them believe that it is important to have information about therapeutic indications of pharmaceuticals to be used (91.8%), their dosage and method of administration (91.1%), contraindications (82.4%), adverse reactions (81.9%) and the simultaneous use of multiple medicines (76.5%). 58.9% of consumers value information about medicine's price. More than 70% of patients often seek information from health professionals and use medicines package information leaflets (PIL), and more than 75% of respondents mainly trust the same sources. 71.5% of respondents read package leaflets, while 42.0% of consumers do this several times. Only 36.7% of respondents completely understand information in a leaflet. Patients in Armenia need medicine information. They prefer to receive information from sources they trust.Many patients do not understand the content of package information leaflets (PILs) due to barriers, which can be removed by introducing appropriate regulatory provisions for their content and readability.

Full Text Available Receipt of adequate amount of accurate patient information on medicines before their use is one of the main cornerstones of the treatment. Without the information medicines cannot be used safely and effectively. Basically, it can be argued that the information is converting the pharmacologically active substance into the medicinal product. Main source of information for patients in Latvia is Package leaflets. Label of medicines and patient information leaflet are drawn up in compliance with regulatory requirements, but for people it is often difficult to understand information contained in the package leaflets due to the complex language. The readability test – introduced as a mandatory requirement for marketing authorization and renewal of marketing authorization of medicines – improves the quality of package leaflets making them more patient “friendly”.

To analyse the level of consistency and updating of the information on pregnancy and lactation provided by patient information leaflets (PILs) of the antirheumatic drugs approved in Argentina. Inconsistencies between the 2016 EULAR Task Force recommendations on the use of anti-rheumatic drugs during pregnancy and lactation and the information provided by PILs of the same drugs approved in Argentina were analysed along with inconsistencies within the PILs of different registered trademarks of these drugs. Eighty-eight PILs of 32 drugs were analysed. Out of the 88 PILs, 50% presented information inconsistencies as to pregnancy. Medications comprised in this group were: hydroxychloroquine, sulfasalazine, azathioprine, tacrolimus, cyclosporine, NSAIDs (during the first two trimesters), celecoxib, some glucocorticoids, colchicine, and some anti-TNF drugs (etanercept, adalimumab and infliximab) during part of the pregnancy. As for lactation, 56% had information inconsistencies. Medications encompassed in this group were: hydroxychloroquine, chloroquine, sulfasalazine, azathioprine, tacrolimus, cyclosporine, NSAIDs, celecoxib, meprednisone, prednisone, colchicine, and anti-TNF drugs. Out of 17 drugs that had more than one registered trademark, information inconsistencies on pregnancy were found in the PILs of sulfasalazine, diclofenac, ibuprofen and methylprednisolone. Concerning lactation, inconsistencies were present in the PILs of hydroxychloroquine, sulfasalazine, diclofenac, ibuprofen, meprednisone, and colchicine. At least half of the PILs of anti-rheumatic drugs analysed in this study had information inconsistencies on pregnancy and lactation. This is a serious state of affairs because the consensual decision-making process between patient and professional may be compromised, which, in turn, may give rise to medical-legal issues.

Bicuspid aortic valve (BAV) disease is heterogeneous and related to valve dysfunction and aortopathy. Appropriate follow up and surveillance of patients with BAV may depend on correct phenotypic categorization. There are multiple classification schemes, however a need exists to comprehensively capture commissure fusion, leaflet asymmetry, and valve orifice orientation. Our aim was to develop a BAV classification scheme for use at MRI to ascertain the frequency of different phenotypes and the consistency of BAV classification. The BAV classification scheme builds on the Sievers surgical BAV classification, adding valve orifice orientation, partial leaflet fusion and leaflet asymmetry. A single observer successfully applied this classification to 386 of 398 Cardiac MRI studies. Repeatability of categorization was ascertained with intraobserver and interobserver kappa scores. Sensitivity and specificity of MRI findings was determined from operative reports, where available. Fusion of the right and left leaflets accounted for over half of all cases. Partial leaflet fusion was seen in 46% of patients. Good interobserver agreement was seen for orientation of the valve opening (κ = 0.90), type (κ = 0.72) and presence of partial fusion (κ = 0.83, p < 0.0001). Retrospective review of operative notes showed sensitivity and specificity for orientation (90, 93%) and for Sievers type (73, 87%). The proposed BAV classification schema was assessed by MRI for its reliability to classify valve morphology in addition to illustrating the wide heterogeneity of leaflet size, orifice orientation, and commissural fusion. The classification may be helpful in further understanding the relationship between valve morphology, flow derangement and aortopathy.

A case of leaflet fracture and embolization of a mitral prosthetic valve is described. A 54-year-old man had received mitral valve replacement with an Edwards-Duromedics 29M prosthetic valve, at 10 years ago. Emergency mitral valve replacement was performed because the patient had severe congestive left heart failure with severe acute mitral regurgitation caused by a fracture in one of the mitral valve leaflets. The leaflet, which was fractured into 2 pieces, was removed from the right common iliac artery at 3 months after valve replacement. Visual inspection revealed that the leaflet contained a midline fracture. The fracture originated within a cavitary erosion pit near the major radius of the leaflet. The patient recovered from acute renal failure, requiring hemodialysis for 80 days, and is currently without complaints. We have used a Duromedics mitral valve in 11 patients, from April 1987 to April 1988. No subsequent valve failure has occurred. The diagnosis, treatment and cause of a mechanical valve fracture are discussed.

To analyze the extent to which Spanish leaflets and drug information on the Net met quality criteria. A descriptive study was conducted comparing readability (REA) and comprehensibility (COM) criteria of a random sample of 77 marketed products of the 12 active ingredients most frequently sold in 2010 in Spain. Leaflets were approved by the Spanish Agency for Medication (AEMPS). Flesch index, DISCERN, ELF, MIDAS and CIRF scales were used to evaluate quality criteria. COM assessment yielded between 63 and 77% of the maximum possible scores on the scales. None of the websites or leaflets met all the quality criteria of the DISCERN, CIRF or MIDAS scales. Four (3%) leaflets met all the 22 quality criteria of ELF. The leaflets showed shortcomings regarding: medication benefits (17 required substantial improvements, 31.5%), correct forms of storage (13, 24.1%), contraindications (12, 22.2%), side effects (11, 20.4%) and precautions to be taken (9, 16.7%). The quality of the information approved by the AEMPS is superior to that which can be found by surfing the Net. More specific information on precautions, complications and how to avoid common patient errors would allow patients the best chance to contribute to their own clinical safety.

The gold-standard treatment of severe mitral regurgitation (MR) due to degenerative disease is valve repair, which is surgically performed with either a leaflet resection or leaflet preservation approach. Recent data suggest that functional mitral stenosis (MS) may occur following valve repair using a leaflet resection strategy, which adversely affects patient prognosis. A randomised comparison of these two approaches to mitral repair on functional MS has not been conducted. This is a prospective, multicentre randomised controlled trial designed to test the hypothesis that leaflet preservation leads to better preservation of mitral valve geometry, and therefore, will be superior to leaflet resection for the primary outcome of functional MS as assessed by 12-month mean mitral valve gradient at peak exercise. Eighty-eight patients with posterior leaflet prolapse will be randomised intraoperatively once deemed by the operating surgeon to feasibly undergo mitral repair using either a leaflet resection or leaflet preservation approach. Secondary end points include comparison of repair strategies with regard to mitral valve orifice area, leaflet coaptation height, 6 min walk test and a composite major adverse event end point consisting of recurrent MR ≥2+, death or hospital readmission for congestive heart failure within 12 months of surgery. Institutional ethics approval has been obtained from all enrolling sites. Overall, there remains clinical equipoise regarding the mitral valve repair strategy that is associated with the least likelihood of functional MS. This trial hopes to introduce high-quality evidence to help surgical decision making in this context.

Surgical replacement of the pulmonary valve (PV) is a common treatment option for congenital pulmonary valve defects. Engineered tissue approaches to develop novel PV replacements are intrinsically complex, and will require methodical approaches for their development. Single leaflet replacement utilizing an ovine model is an attractive approach in that candidate materials can be evaluated under valve level stresses in blood contact without the confounding effects of a particular valve design. In the present study an approach for optimal leaflet shape design based on finite element (FE) simulation of a mechanically anisotropic, elastomeric scaffold for PV replacement is presented. The scaffold was modeled as an orthotropic hyperelastic material using a generalized Fung-type constitutive model. The optimal shape of the fully loaded PV replacement leaflet was systematically determined by minimizing the difference between the deformed shape obtained from FE simulation and an ex-vivo microCT scan of a native ovine PV leaflet. Effects of material anisotropy, dimensional changes of PV root, and fiber orientation on the resulting leaflet deformation were investigated. In-situ validation demonstrated that the approach could guide the design of the leaflet shape for PV replacement surgery. Copyright © 2012 Elsevier Ltd. All rights reserved.

Towards a new kind of patient information leaflet?

There is general consensus amongst patients, academics and regulatory agencies that mandatory PILs, which accompany all medication in the EU, do not communicate effectively with patients. This is problematic as patients have stated that they want to receive information on their medication; they are...... with the interactive situation (Holmström & Röing, 2010), for the medium of print. I performed such a translation by considering the affordances of print as opposed to live interaction, developing the evaluative optic of patient centeredness for texts. The dissertation takes a discursive approach, employing.......g. treatments for rheumatoid arthritis and depression) than for minor, acute, physical conditions (e.g. indigestion and bacterial eye infections). The main practical implication of this finding is that the appropriateness of including greater patient centeredness in PILs seems contingent on the nature...

Evidence-based health information (EBHI) can support informed choice regarding whether or not to attend colorectal cancer (CRC) screening. The present study aimed to assess if German leaflets and booklets appropriately inform consumers on the benefits and harms of CRC screening. A systematic search for print media on CRC screening was performed via email enquiry and internet search. The identified documents were assessed for the presence and correctness of information on benefits and harms by two reviewers independently using a comprehensive list of criteria. Many of the 28 leaflets and 13 booklets identified presented unbalanced information on the benefits and harms of CRC screening: one-third did not provide any information on harms. Numeracy information was often lacking. Ten cross-language examples of common misinterpretations or basically false and misleading information were identified. Most of the CRC screening leaflets and booklets in Germany do not meet current EBHI standards. After the study, the publishers of the information materials were provided feedback, including a discussion of our findings. The results can be used to revise existing information materials or to develop new materials that provide correct, balanced, quantified, understandable and unbiased information on CRC screening.

Mitral valve prolapse without proper monitoring might lead to a severe mitral valve failure which eventually leads to a sudden death. Additional information on the mitral valve leaflet condition against the backflow volume would be an added advantage to the medical practitioner for their decision on the patients' treatment. A study on two dimensional echocardiography images has been conducted and the correlations between the backflow volume of the mitral regurgitation and mitral valve leaflet Young modulus have been obtained. Echocardiogram images were analyzed on the aspect of backflow volume percentage and mitral valve leaflet dimensions on different rates of backflow volume. Young modulus values for the mitral valve leaflet were obtained by using the principle of elastic deflection and deformation on the mitral valve leaflet. The results show that the backflow volume increased with the decrease of the mitral valve leaflet Young modulus which also indicate the condition of the mitral valve leaflet approaching failure at high backflow volumes. Mitral valve leaflet Young modulus values obtained in this study agreed with the healthy mitral valve leaflet Young modulus from the literature. This is an initial overview of the trend on the prediction of the behaviour between the fluid and the structure of the blood and the mitral valve which is extendable to a larger system of prediction on the mitral valve leaflet condition based on the available echocardiogram images.

The package leaflet included in the packaging of all medicinal products plays an important role in the transmission of medicine-related information to patients. Therefore, in 2009, the European Commission published readability guidelines to try to ensure that the information contained in the package leaflet is understood by patients. The main objective of this study was to calculate and compare the readability levels and length (number of words) of the package leaflets for biological medicines in 2007, 2010, and 2013. The sample of this study included 36 biological medicine package leaflets that were downloaded from the European Medicines Agency website in three different years: 2007, 2010, and 2013. The readability of the selected package leaflets was obtained using the following readability formulas: SMOG grade, Flesch-Kincaid grade level, and Szigriszt's perspicuity index. The length (number of words) of the package leaflets was also measured. Afterwards, the relationship between these quantitative variables (three readability indexes and length) and categorical (or qualitative) variables were analyzed. The categorical variables were the year when the package leaflet was downloaded, the package leaflet section, type of medicine, year of authorization of biological medicine, and marketing authorization holder. The readability values of all the package leaflets exceeded the sixth-grade reading level, which is the recommended value for health-related written materials. No statistically significant differences were found between the three years of study in the readability indexes, although differences were observed in the case of the length (P=.002), which increased over the study period. When the relationship between readability indexes and length and the other variables was analyzed, statistically significant differences were found between package leaflet sections (Preadability indexes (SMOG grade and Flesch-Kincaid grade level: r(2)=.92; SMOG grade and Szigriszt

Leaflet escape is a mode of structural valve failure for mechanical prostheses. This complication previously has been reported for both monoleaflet and bileaflet valve models. We report 2 leaflet escape occurrences observed in 2 patients who underwent valve replacement with a TRI Technologies valve prosthesis. At the University of Padua, between November 2000 and February 2002, 36 TRI Technologies valve prostheses (26 aortic and 10 mitral) were implanted in 34 patients (12 women and 22 men) with a mean age of 59.9+/-10.3 years (range, 30 to 75 years). There were 5 deaths: 3 in hospital, 1 early after discharge, and 1 late. Two patients experienced a catastrophic prosthetic leaflet escape; the first patient was a 52-year-old man who died 10 days after aortic valve and ascending aorta replacement, and the second was a 58-year-old man who underwent a successful emergency reoperation 20 months after mitral valve replacement. Examination of the explanted prostheses showed in both cases a leaflet escape caused by a leaflet's pivoting system fracture. Prophylactic replacement was then successfully accomplished so far in 12 patients, without evidence of structural valve failure in any of them. Among other significant postoperative complications, we observed 3 major thromboembolisms, 1 hemorrhage, and 1 paravalvular leak. These catastrophes prompted us to interrupt the implantation program, and they cast a shadow on the durability of the TRI Technologies valve prosthesis because of its high risk of structural failure.

We sought to examine whether elongation of the mitral valve leaflets in patients with hypertrophic cardiomyopathy (HCM) is synergistic to septal wall thickness (SWT) in the development of left ventricular outflow tract obstruction (LVOTO). HCM is a common genetic cardiac disease characterized by asymmetric septal hypertrophy and predisposition towards LVOTO. It has been reported that elongation of the mitral valve leaflets may be a primary phenotypic feature and contribute to LVOTO. However, the relative contribution of this finding versus SWT has not been studied. 152 patients (76 with HCM and 76 non-diseased age, race and BSA-matched controls) and 18 young, healthy volunteers were studied. SWT and the anterior mitral valve leaflet length (AMVLL) were measured using cine MRI. The combined contribution of these variables (SWT × AMVLL) was described as the Septal Anterior Leaflet Product (SALP). Peak LVOT pressure gradient was determined by Doppler interrogation and defined as "obstructive" if ≥ 30 mmHg. Patients with HCM were confirmed to have increased AMVLL compared with controls and volunteers (p SALP were significantly higher in patients with LVOTO (N = 17) versus without. SALP showed modest improvement in predictive accuracy for LVOTO (AUC = 0.81) among the HCM population versus SWT alone (AUC = 0.77). However, in isolated patients this variable identified patients with LVOTO despite modest SWT. Elongation of the AMVLL is a primary phenotypic feature of HCM. While incremental contributions to LVOTO appear modest at a population level, specific patients may have dominant contribution to LVOTO. The combined marker of SALP allows for maintained identification of such patients despite modest increases in SWT.

OBJECTIVE To review studies on the readability of package leaflets of medicinal products for human use. METHODS We conducted a systematic literature review between 2008 and 2013 using the keywords "Readability and Package Leaflet" and "Readability and Package Insert" in the academic search engine Biblioteca do Conhecimento Online, comprising different bibliographic resources/databases. The preferred reporting items for systematic reviews and meta-analyses criteria were applied to prepare the draft of the report. Quantitative and qualitative original studies were included. Opinion or review studies not written in English, Portuguese, Italian, French, or Spanish were excluded. RESULTS We identified 202 studies, of which 180 were excluded and 22 were enrolled [two enrolling healthcare professionals, 10 enrolling other type of participants (including patients), three focused on adverse reactions, and 7 descriptive studies]. The package leaflets presented various readability problems, such as complex and difficult to understand texts, small font size, or few illustrations. The main methods to assess the readability of the package leaflet were usability tests or legibility formulae. Limitations with these methods included reduced number of participants; lack of readability formulas specifically validated for specific languages (e.g., Portuguese); and absence of an assessment on patients literacy, health knowledge, cognitive skills, levels of satisfaction, and opinions. CONCLUSIONS Overall, the package leaflets presented various readability problems. In this review, some methodological limitations were identified, including the participation of a limited number of patients and healthcare professionals, the absence of prior assessments of participant literacy, humor or sense of satisfaction, or the predominance of studies not based on role-plays about the use of medicines. These limitations should be avoided in future studies and be considered when interpreting the results.

Designing patient-focused information: an opportunity for communicating anatomically related information.

Literature clearly demonstrates that there has been a large increase in the time devoted to teaching oral communication skills within medical curricula worldwide. In contrast, the ability to communicate with patients through written means does not appear to be a feature in many programmes, despite its fundamental importance in creating understanding of medicine within the general population. This article investigates one way patient-centered written communication has been integrated into part of the early training years of medical students using anatomically related material as a focus. Following a series of interactive seminars and debates as part of a student-selected component, students were asked to prepare a patient-focused information leaflet on a particular birth defect. The leaflets included aspects of anatomy and embryology as well as causes of the birth defect, signs and symptoms, treatments, outlook, and support mechanisms. Evaluation of the leaflets using set marking criteria and readability indexes showed that students had successfully targeted the chosen audiences. Feedback showed that the component was rated highly by the students in terms of quality, usefulness, and interest. Students viewed sessions as an excellent forum for appreciating the importance of and developing their own effective written communication skills. It is hoped that such developments will enhance the capacity of all potential doctors to communicate more effectively with patients and colleagues in both the written and spoken form.

Carla Pires

Full Text Available CONTEXT AND OBJECTIVES: Package leaflets are necessary for safe use of medicines. The aims of the present study were: 1 to assess the compliance between the content of the package leaflets and the specifications of the pharmaceutical regulations; and 2 to identify potential safety issues for patients. DESIGN AND SETTING: Qualitative descriptive study, involving all the package leaflets of branded medicines from the three most consumed therapeutic groups in Portugal, analyzed in the Department of Pharmacoepidemiology, School of Pharmacy, University of Lisbon. METHODS: A checklist validated through an expert consensus process was used to gather the data. The content of each package leaflet in the sample was classified as compliant or non-compliant with compulsory regulatory issues (i.e. stated dosage and descriptions of adverse reactions and optional regulatory issues (i.e. adverse reaction frequency, symptoms and procedures in cases of overdose. RESULTS: A total of 651 package leaflets were identified. Overall, the package leaflets were found to be compliant with the compulsory regulatory issues. However, the optional regulatory issues were only addressed in around half of the sample of package leaflets, which made it possible to identify some situations of potentially compromised drug safety. CONCLUSION: Ideally, the methodologies for package leaflet approval should be reviewed and optimized as a way of ensuring the inclusion of the minimum essential information for safe use of medicines.

Mitral valve replacement with posterior leaflet preservation was shown beneficial for postoperative left vetricular (LV) performance in patients with mitral regurgitation. Some authors find it beneficial even for the long term LV function. We investigated a long term effect of this technique in patients with rheumatic mitral stenosis. We studied 20 patents with mitral valve replacement due to rheumatic mitral stenosis, in the period from January 1988 to December 1989. In group A (10 patients) both leaflets and coresponding chordal excision was performed, while in group B (10 patients) the posterior leaflet was preserved. In all patients a Carbomedics valve was inserted. We compared clinical pre and postoperative status, as well as hemodynamic characteristics of the valve and left ventricle in both groups. Control echocardiographyc analysis included: maximal (PG) and mean (MG) gradients; effective valve area (AREA); telediastolic (TDV) and telesystolic (TSV) LV volume; stroke volume (SV); ejection fraction (EF); fractional shortening (FS) and segmental LV motion. The mean size of inserted valve was 26.6 in group A and 27.2 in group B. Hemodynamic data: PG (10.12 vs 11.1); MG (3.57 vs 3.87); AREA (2.35 vs 2.30); TDV 126.0 vs 114.5); TSV (42.2 vs 36.62); SV (83.7 vs 77.75); EF (63.66 vs 67.12); FS (32.66 vs 38.25). Diaphragmal segmental hypokinesis was evident in one patient from group A and in two patients from group B. In patients with rheumatic stenosis, posterior leaflet preservation did not have increased beneficial effect on left ventricular performance during long-term follow-up. An adequate posterior leaflet preservation does not change hemodynamic valvular characteristics even after long-term follow-up.

A self care leaflet of 50 pages was distributed in Tingvoll, a municipality with 3,500 inhabitants. The leaflet gives advice about self treatment and prevention of common health problems, and guidelines for contacting the health services. In surveys conducted just before and 10 months after the distribution, we documented -- how the leaflet was accepted and used --changes in knowledge about the health problems mentioned in the leaflet. The leaflet was well accepted. It was characterized as easy to read and to use. 10 months after distribution to read and to use. 10 months after distribution 90% found it within five minutes. 63% used the leaflet when they had a health problem. 90% of those using the leaflet felt more sure that they acted correctly after consulting it, and 60% changed their mind about consulting a general practitioner. We consider the level of knowledge about health problems to be low. The evaluation showed increased knowledge in all groups, except for persons "responsible for caring for elderly relatives". The increase was most marked for "men" and for "persons with health education".

Full Text Available This paper presents partial results of primary research on consumer purchasing behaviour with regards to the utilization of product leaflets. It deals with the consumer reaction on the use of these leaflets. The main goal is to assess the impulse to purchase goods on the basis of promotional leaflets in mailboxes, depending on the personal characteristics of the consumer. Partial goals are a brief theoretical basis of the examined issues and selected results of secondary research on consumer behaviour based on available statistical data and information. Consumer behaviour changes drastically in times of crisis. Czech consumer is addressed daily by a specific communication media of store chains – the leaflets. These appear daily in mailboxes and are generally positively accepted. There are also negative opinions, both from consumers as well as the EU. Respondents were asked about their financial situation, to what extent they change their buying behaviour with respect to the income level of households. It turned out that the impulse to purchase goods on the basis of promotional leaflets in mailboxes does not depend on the age and sex of respondents, but depends on the income level and education. The largest proportion of respondents considers leaflets because of promotional discounts.

Overcoming the knowledge-behavior gap: The effect of evidence-based HPV vaccination leaflets on understanding, intention, and actual vaccination decision.

Informed decision making requires transparent and evidence-based (=balanced) information on the potential benefit and harms of medical preventions. An analysis of German HPV vaccination leaflets revealed, however, that none met the standards of balanced risk communication. We surveyed a sample of 225 girl-parent pairs in a before-after design on the effects of balanced and unbalanced risk communication on participants' knowledge about cervical cancer and the HPV vaccination, their perceived risk, their intention to have the vaccine, and their actual vaccination decision. The balanced leaflet increased the number of participants who were correctly informed about cervical cancer and the HPV vaccine by 33 to 66 absolute percentage points. In contrast, the unbalanced leaflet decreased the number of participants who were correctly informed about these facts by 0 to 18 absolute percentage points. Whereas the actual uptake of the HPV vaccination 14 months after the initial study did not differ between the two groups (22% balanced leaflet vs. 23% unbalanced leaflet; p=.93, r=.01), the originally stated intention to have the vaccine reliably predicted the actual vaccination decision for the balanced leaflet group only (concordance between intention and actual uptake: 97% in the balanced leaflet group, rs=.92, p=.00; 60% in the unbalanced leaflet group, rs=.37, p=.08). In contrast to a unbalanced leaflet, a balanced leaflet increased people's knowledge of the HPV vaccination, improved perceived risk judgments, and led to an actual vaccination uptake, which first was robustly predicted by people's intention and second did not differ from the uptake in the unbalanced leaflet group. These findings suggest that balanced reporting about HPV vaccination increases informed decisions about whether to be vaccinated and does not undermine actual uptake. Copyright © 2014 The Authors.

Surgical techniques currently used for the repair of Ebstein's anomaly comprise reconstruction of the tricuspid valve mechanism at the level of the true annulus with or without plication of the atrialized right ventricle. However, performing this procedure for patients with a dysmorphic anterior leaflet (i.e., insufficient leaflet tissue and decreased mobility due to tethering) may necessitate technical modifications. A retrospective review was performed of 31 patients (seven males and 24 females, median age at operation 31 years) with Ebstein's anomaly, who underwent tricuspid valve repair between March 2002 and December 2014. The original Hetzer technique (annulus to annulus approximation) was employed for six patients with a well-formed anterior leaflet. In 25 patients, the tricuspid valve mechanism was restored at the displaced septal leaflet by approximating the anterior leaflet attachment in the true annulus to the displaced septal leaflet attachment in the mid-septum. A bidirectional superior cavopulmonary anastomosis was added in 27 of 31 (87%) patients. No early or late death occurred during the median follow-up of 66 months (1-138 months). Immediate postoperative tricuspid regurgitation was trivial to mild in 22 patients, and the median preoperative, immediate postoperative, and last follow-up tricuspid regurgitation jet areas in 21 adult patients were 23.3 cm2, 10.4 cm2, and 7.0 cm2, respectively. Two patients underwent reoperation at 81 and 119 months postoperatively. Five-year freedom from severe tricuspid regurgitation or reoperation was 93.2%. Restoration of the tricuspid valve mechanism at the level of displaced septal leaflet leads to excellent long-term outcomes. The addition of the bidirectional superior cavopulmonary anastomosis has contributed to the success of this technique. © 2016 Wiley Periodicals, Inc.

This study focuses on the typical semantic systems extracted from hospital staff communicative resources which attempt to validate information as an "object" to be transferred to patients. We describe the models of textual communication in 58 patient information leaflets from five hospital units in Brazil, gathered from 1996 to 2002. Three categories were identified, based on the theory of speech acts (Austin, Searle, and Habermas): 1) cognitive-instrumental utterances: descriptions by means of technical terms validated by self-referred, incomplete, or inaccessible argumentation, with an implicit educational function; 2) technical-directive utterances: self-referred (to the context of the source domains), with a shifting of everyday acts to a technical terrain with a disciplinary function and impersonal features; and 3) expressive modulations: need for inter-subjective connections to strengthen bonds of trust and a tendency to use childish arguments. We conclude that the three categories displayed: fragmentary sources; assumption of univocal messages and invariable use of information (idealized motivations and interests, apart from individualized perspectives); and assumption of universal interests as generators of knowledge.

To investigate the readability and suitability of sexual health promotion leaflets. Application of SMOG, FRY and SAM tests to assess the readability and suitability of a selection of sexual health leaflets. SMOG and FRY scores illustrate an average reading level of grade 9. SAM scores indicate that 59% of leaflets are superior in design and 41% are average in design. Leaflets generally perform well in the categories of content, literacy demand, typography and layout. They perform poorly in use of graphics, learning stimulation/motivation and cultural appropriateness. Sexual health leaflets have a reading level that is too high. Leaflets perform well on the suitability scores indicating they are reasonably suitable. There are a number of areas where sexual health leaflets could improve their design. Numerous practical techniques are suggested for improving the readability and suitability of sexual health leaflets. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Abstract Background Hundreds of thousands of volunteers take part in medical research, but many will never hear from researchers about what the study revealed. There is a growing demand for the results of randomised trials to be fed back to research participants both for ethical research practice and for ensuring their co-operation in a trial. This study aims to determine participants' preferences for type of leaflet (short versus long used to summarise the findings of a randomised trial; and to test whether certain characteristics explained participants' preferences. Methods 553 participants in a randomised trial about General Practitioners' access to Magnetic Resonance Imaging for patients presenting with suspected internal derangement of the knee were asked in the final follow-up questionnaire whether they would like to be fed back the results of the trial. Participants who agreed to this were included in a postal questionnaire survey asking about their preference, if any, between a short and a long leaflet and what it was about the leaflet that they preferred. Multinomial logistic regression was used to test whether certain demographics of responding participants along with treatment group explained whether a participant had a preference for type of leaflet or no preference. Results Of the participants who returned the final follow-up questionnaire, 416 (88% agreed to receive the results of the trial. Subsequently 132 (32% participants responded to the survey.

Informed consent and placebo effects: a content analysis of information leaflets to identify what clinical trial participants are told about placebos.

Full Text Available Placebo groups are used in randomised clinical trials (RCTs to control for placebo effects, which can be large. Participants in trials can misunderstand written information particularly regarding technical aspects of trial design such as randomisation; the adequacy of written information about placebos has not been explored. We aimed to identify what participants in major RCTs in the UK are told about placebos and their effects.We conducted a content analysis of 45 Participant Information Leaflets (PILs using quantitative and qualitative methodologies. PILs were obtained from trials on a major registry of current UK clinical trials (the UKCRN database. Eligible leaflets were received from 44 non-commercial trials but only 1 commercial trial. The main limitation is the low response rate (13.5%, but characteristics of included trials were broadly representative of all non-commercial trials on the database. 84% of PILs were for trials with 50:50 randomisation ratios yet in almost every comparison the target treatments were prioritized over the placebos. Placebos were referred to significantly less frequently than target treatments (7 vs. 27 mentions, p<001 and were significantly less likely than target treatments to be described as triggering either beneficial effects (1 vs. 45, p<001 or adverse effects (4 vs. 39, p<001. 8 PILs (18% explicitly stated that the placebo treatment was either undesirable or ineffective.PILs from recent high quality clinical trials emphasise the benefits and adverse effects of the target treatment, while largely ignoring the possible effects of the placebo. Thus they provide incomplete and at times inaccurate information about placebos. Trial participants should be more fully informed about the health changes that they might experience from a placebo. To do otherwise jeopardises informed consent and is inconsistent with not only the science of placebos but also the fundamental rationale underpinning placebo controlled

MitraClip (Abbott Vascular) therapy has been reported to be an effective procedure for mitral regurgitation, especially in high-risk patients. Recently, the novel pushing maneuver technique has been described for approaching restricted and short posterior leaflets with a pigtail catheter in order to facilitate grasping of the clip. However, complications or unexpected situations may occur. We report the case of an 84-year-old patient who underwent MitraClip implantation wherein the pushing maneuver was complicated by the clip accidentally gripping the pigtail catheter along with the two leaflets.

General practice staff are reluctant to discuss sexual health opportunistically in all consultations. Health promotion materials may help alleviate this barrier. Chlamydia screening promotion posters and leaflets, produced by the English National Chlamydia Screening Programme (NCSP), have been available to general practices, through local chlamydia screening offices, since its launch. In this study we explored the attitudes of general practice staff to these screening promotional materials, how they used them, and explored other promotional strategies to encourage chlamydia screening. Twenty-five general practices with a range of screening rates, were purposively selected from six NCSP areas in England. In focus groups doctors, nurses, administrative staff and receptionists were encouraged to discuss candidly their experiences about their use and opinions of posters, leaflets and advertising to promote chlamydia screening. Researchers observed whether posters and leaflets were on display in reception and/or waiting areas. Data were collected and analysed concurrently using a stepwise framework analytical approach. Although two-thirds of screening practices reported that they displayed posters and leaflets, they were not prominently displayed in most practices. Only a minority of practices reported actively using screening promotional materials on an ongoing basis. Most staff in all practices were not following up the advertising in posters and leaflets by routinely offering opportunistic screening to their target population. Some staff in many practices thought posters and leaflets would cause offence or embarrassment to their patients. Distribution of chlamydia leaflets by receptionists was thought to be inappropriate by some practices, as they thought patients would be offended when being offered a leaflet in a public area. Practice staff suggested the development of pocket-sized leaflets. The NCSP should consider developing a range of more discrete but eye

Leaflet escape of prosthetic valve is rare but potentially life threatening. Early diagnosis is essential on account of avoiding mortality, and emergency surgical correction is compulsory. This complication has previously been reported for both monoleaflet and bileaflet valve models. A 30-year-old man who had undergone mitral valve replacement with a bileaflet valve 8 years prior at another center was admitted with acute-onset with cardiogenic shock as an emergency case. Transthoracic echocardiograms showed acute-starting severe mitral regurgitation associated with prosthetic mitral valve. There was a suspicious finding of a single prosthetic mitral leaflet. But the problem related with the valve wasn't specifically determined. The patient underwent emergent surgery for replacement of the damaged prosthetic valves immediately. There was no tissue impingement and thrombosis, one of the two leaflets was absent, and there were no signs of endocarditis or pannus formation in the prosthetic valve. The missing leaflet could not be found within the cardiac cavity. The abdominal fluoroscopic study and plain radiography were unable to detect the escaped leaflet during surgery. The damaged valve was removed and a replacement 29 mm bileaflet mechanical valve was inserted by right lateral thoracotomy. After post-operative week one, the abdominal computed tomography scan and the ultrasound showed the escaped leaflet in the left femoral artery. Fifteen days after the surgery the escaped leaflet was removed safely from the left femoral artery and the patient made a complete recovery. The escaped leaflet showed a fracture of one of the pivot systems caused by structural failure. Early cardiac surgery should be applied because of life-threatening problems.

2003-08-01

Review was made of publications that describe experience with printed material distributed to the lay public in hospital institutions. From the 146 leaflets examined, those aimed at professionals or disabled people, thus leaving 75 papers that illustrate the present pattern for the rationality behind the production, use and evaluation of this type of resource. In a general manner, such leaflets invest in the power of "ideal printed information" to align behavior with the hospital's biomedical agenda. The underlying rationality that permeates them perceives the "perfect information package" as one that efficiently describes its technical content for the purpose of unidirectional persuasion, is up-to-date in relation to readability scales and embellished by graphic design, and emphasizes the priorities defined by the professionals. Such "communication prostheses" should be capable of electronic validation by means of software suitable for proportioning the "doses" to the subject matter. Information as a drug, cognitivism, the lack of research on message reception and the need for communicative action for the deconstruction of systems of closed thinking within the hospital environment have been discussed.

Energy consumption of small refrigerators - Information leaflet; Merkblatt Kleinkuehlschrank

2009-07-01

In this leaflet published by the Swiss Federal Office of Energy (SFOE), the energy consumption of small refrigerators with a capacity of less than 100 litres is reported on. Such small refrigerators are often used in hotel rooms or in campers. It is noted that, in comparison, a typical, 150 litre class A++ domestic refrigerator uses only a fraction of the amount of energy used by such small refrigerators. The results of measurements made according to EN 153 and ISO 15502 norms are discussed. Recommendations are made on the purchase and operation of these small refrigerators.

This project aimed to improve patients' knowledge on the importance of hand hygiene. It involved providing patients with a patient and family education on the importance of hand hygiene using a patient information leaflet that introduces the rationale of hand hygiene, possible consequences of poor hand hygiene, and the seven steps of hand hygiene. This projected used a preimplementation and postimplementation audit strategy using the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research Into Practice programs. The implementation occurred in three phases over a period of 6 months from January 2014 to June 2014. The audits took place in two orthopaedic wards in a large acute care setting tertiary hospital in Singapore and involved a sample size of 54 patients. It involved going through the medical records of the cases, assessment of patient knowledge based on the audit criteria, and checking if the patients received the patient information leaflet on hand hygiene. The postimplementation audit found significant improvements in all three audit criteria. The percentage of patients who demonstrated knowledge in the importance of hand hygiene saw an improvement of 48.1%. There was an improvement of 44.5% in nurses' compliance to the documentation of patient education being carried out. The percentage of patients who received a patient information leaflet on hand hygiene saw an increase of 36.1%. This project demonstrated that a preimplementation and postimplementation audit is a viable method to implement change and translate evidence into practice. Through this project, patients gained an understanding on the importance of hand hygiene and could take better ownership of their well being. This may potentially improve hospitalization experience and benefit health outcomes. The positive results of this project are contributed by the enthusiastic involvement of all the stakeholders, from patients and their caregivers to the bedside

Movement influences carambola leaflet chlorophyll fluorescence and temperature under sunny conditions

Leaflets of 'Arkin', 'B-10', 'Kary', and 'Sri Kembangan' carambola (Averrhoa carambola L.) trees were restrained in a horizontal position for 3.5 h during midday under full sun conditions to determine the influence of overriding natural leaflet movement on adaxial chlorophyll fluorescence and temperature. Induced chlorophyll fluorescence obtained after 30 minutes of dark adaptation following the period of full sun exposure was affected by leaflet movement. Restrained leaflets exhibited a variable fluorescence (Fv)/peak fluorescence (Fm) of 0.48, while that of unrestrained leaflets was 0.65. Adaxial leaflet temperature of restrained leaflets was 6C higher than that of leaflets that were allowed to move. The influence of leaflet movement on temperature or chlorophyll fluorescence was not different among the four cultivars. However, mean Fv/Fm of 'Kary' and 'Sri Kembangan' was lower than that of 'B-10'. Our results indicate that the ability of carambola to change leaflet angle leads to lower temperature and higher photochemical efficiency than occurs when leaflets are not allowed to move naturally (vertically orient) under full sun conditions

Consumer Medicine Information (CMI) is a brand-specific and standardized source of written medicine information available in Australia for all prescription medicines. Side-effect information is poorly presented in CMI and may not adequately address consumer information needs. To explore consumer opinions on (i) the presentation of side-effect information in existing Australian CMI leaflets and alternative study-designed CMIs and (ii) side-effect risk information and its impact on treatment decision making. Fuzzy trace, affect heuristic, frequency hypothesis and cognitive-experiential theories were applied when revising existing CMI side-effects sections. Together with good information design, functional linguistics and medicine information expertise, alternative ramipril and clopidogrel CMI versions were proposed. Focus groups were then conducted to address the study objectives. Three focus groups (n = 18) were conducted in Sydney, Australia. Mean consumer age was 58 years (range 50-65 years), with equal number of males and females. All consumers preferred the alternative CMIs developed as part of the study, with unequivocal preference for the side-effects presented in a simple tabular format, as it allowed quick and easy access to information. Consumer misunderstandings reflected literacy and numeracy issues inherent in consumer risk appraisal. Many preferred no numerical information and a large proportion preferred natural frequencies. One single method of risk presentation in CMI is unable to cater for all consumers. Consumer misunderstandings are indicative of possible health literacy and numeracy factors that influence consumer risk appraisal, which should be explored further. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

Patient representatives' views on patient information in clinical cancer trials.

Patient enrolment into clinical trials is based on oral information and informed consent, which includes an information sheet and a consent certificate. The written information should be complete, but at the same time risks being so complex that it may be questioned if a fully informed consent is possible to provide. We explored patient representatives' views and perceptions on the written trial information used in clinical cancer trials. Written patient information leaflets used in four clinical trials for colorectal cancer were used for the study. The trials included phase I-III trials, randomized and non-randomized trials that evaluated chemotherapy/targeted therapy in the neoadjuvant, adjuvant and palliative settings. Data were collected through focus groups and were analysed using inductive content analysis. Two major themes emerged: emotional responses and cognitive responses. Subthemes related to the former included individual preferences and perceptions of effect, while subthemes related to the latter were comprehensibility and layout. Based on these observations the patient representatives provided suggestions for improvement, which largely included development of future simplified and more attractive informed consent forms. The emotional and cognitive responses to written patient information reported by patient representatives provides a basis for revised formats in future trials and add to the body of information that support use of plain language, structured text and illustrations to improve the informed consent process and thereby patient enrolment into clinical trials.

Decision-making during pregnancy regarding different options of care can be difficult, particularly when risks of intervention versus no intervention for mother and baby are unclear. Unbiased information and support for decision making may be beneficial in these situations. The management of normal pregnancies at and beyond term is an example of such a situation. In order to determine the need to develop an evidence-based decision aid this paper searches, analyses and appraises patient decision aids and patient information leaflets regarding care options in cases of late term and post-term pregnancies, including complementary and alternative medicine (CAM). A literature search was carried out in a variety of lay and medical databases. written information related to uncomplicated singleton pregnancies and targeted at lay people. Analysis and appraisal of included material by means of quality criteria was set up based on the International Patient Decision Aid Standards accounting for evidence-basing of CAM options. Inclusion of two decision aids and eleven leaflets from four decision aids and sixteen leaflets. One decision aid met the quality criteria almost completely, the other one only insufficiently despite providing some helpful information. Only one leaflet is of good quality, but cannot substitute a decision aid. There is an urgent need for the design of an evidence-based decision aid of good quality for late-term or post-term pregnancy, particularly in German language.

The escape of the prosthetic heart valve disc is one of the causes of prosthetic dysfunction that requires emergency surgery. The removal of the embolized disc should be carried out because of the risk of a progressive extrusion on the aortic wall. Several imaging techniques can be used for the detection of the missing disc localization. In this report we describe a 32-year-old man who underwent mitral valve replacement with a Tri-technologies bileaflet valve three years ago, and was admitted in cardiogenic shock. Transesophageal echocardiography showed acute-onset massive mitral regurgitation. The patient underwent emergency replacement of the prosthetic valve. Only one of the two leaflets remained in the removed prosthetic valve. The missing leaflet could not be found within the cardiac cavity. The abdominal fluoroscopic study and plain radiography were unable to detect the escaped leaflet. The abdominal computed tomography scan and the ultrasound showed the escaped leaflet in the terminal portion of the aortic bifurcation. To retrieve the embolized disc laparotomy and aortotomy were performed three months later. The escaped leaflet shows a fracture of one of the pivot systems caused by structural failure. This kind of failure mode is usually the result of high stress concentration.

Supra-annular Valve-in-Valve implantation reduces blood stasis on the transcatheter aortic valve leaflets.

Leaflet thrombosis following transcatheter aortic valve replacement (TAVR) and Valve-in-Valve (ViV) procedures has been increasingly recognized. This study aimed to investigate the effect of positioning of the transcatheter aortic valve (TAV) in ViV setting on the flow dynamics aspect of post-ViV thrombosis by quantifying the blood stasis in the intra-annular and supra-annular settings. To that end, two idealized computational models, representing ViV intra-annular and supra-annular positioning of a TAV were developed in a patient-specific geometry. Three-dimensional flow fields were then obtained via fluid-solid interaction modeling to study the difference in blood residence time (BRT) on the TAV leaflets in the two settings. At the end of diastole, a strip of high BRT (⩾1.2s) region was observed on the TAV leaflets in the ViV intra-annular positioning at the fixed boundary where the leaflets are attached to the frame. Such a high BRT region was absent on the TAV leaflets in the supra-annular positioning. The maximum value of BRT on the surface of non-, right, and left coronary leaflets of the TAV in the supra-annular positioning were 53%, 11%, and 27% smaller compared to the intra-annular positioning, respectively. It was concluded that the geometric confinement of TAV by the leaflets of the failed bioprosthetic valve in ViV intra-annular positioning increases the BRT on the leaflets and may act as a permissive factor in valvular thrombosis. The absence of such a geometric confinement in the ViV supra-annular positioning leads to smaller BRT and subsequently less likelihood of leaflet thrombosis. Copyright © 2017 Elsevier Ltd.

A patient required emergency mitral valve replacement and extracorporeal membrane oxygenation (ECMO) support for acute biventricular failure. The left ventricular (LV) vent inserted via the left upper pulmonary vein induced thrombotic immobilization of a prosthetic valve leaflet, with significant intra-prosthesis regurgitation after ECMO explantation. Therefore, the left atrium was opened on the beating heart during conventional extracorporeal circulation, all prosthesis leaflets were excised and a 29-mm expandable Edwards Sapien prosthesis was inserted within the scaffold of the original prosthesis under direct vision. This case illustrates the benefits and potential problems of LV venting on ECMO support, and a rapid and safe way of replacing the prosthesis leaflets in a critical situation. © The Author 2015.

Delay in seeking care is one of the critical issues in tuberculosis (TB) control among homeless persons in Japan. Yet knowledge of and attitude towards TB among homeless persons have remained unclear and limited efforts have been made to disseminate information related to TB among homeless persons. To evaluate the effect of TB leaflets, produced and distributed to homeless persons by a group of ex-homeless TB patients, and to understand what homeless persons know about TB. Self-administered questionnaire was conducted among homeless persons before and after distribution of the TB leaflets. Changes in the responses to each question were also subjected to principal component analysis to group questions into types according to response patterns and identify constructs of TB-related knowledge. Results of 88 participants were analyzed. TB knowledge score related to risks and symptoms significantly improved after the intervention (from 54.3% to 70.6%, p < 0.05), while knowledge on treatment cost did not. Two components were identified, namely, the "improvement in TB impression" and "improvement in TB knowledge". TB leaflets were effective in improving certain aspects of TB knowledge. However, its effect on knowledge regarding treatment cost, which may be crucial in improving delay, was limited and thus the messages need to be revised.

Different techniques have been used for exposure of ventricular septal defect (VSD) margins when there is crowding of the VSD anatomy by tricuspid valve (TV) subvalvar apparatus. The aim of this study was to compare surgical outcomes, for the two techniques of TV leaflet detachment and the rarely described TV chordal detachment for hard-to-expose VSDs. Patients undergoing transatrial VSD repair were identified from our institutional database. Follow-up echocardiography and patient data were obtained from medical records. Between 1/2005-8/2016, 130 isolated conoventricular VSDs were repaired. Among these, 26patients had leaflet detachment, while 15 underwent chordal detachment, and 89 had regular VSD repair (reference group). There was no significant difference between the groups in age, weight, postoperative length-of-stay, genetic/syndromic abnormalities, time-to-extubation, and left and right ventricular systolic function. The cardiopulmonary bypass and cross-clamp time were significantly higher in leaflet detachment group, when compared with reference group (118+28vs102+32, p=0.02; and 73+20vs61+23, p=0.01, respectively). Echocardiographic follow-up were available for 87patients at a mean of 2.6years (1month-11years). Tricuspid regurgitation was rated as none or trivial in 66(76%), mild in 20(23%) and moderate in one reference group patient. There was no difference in presence of residual VSD, or degree of tricuspid regurgitation amongst the three groups. There was no reoperation for tricuspid regurgitation. Tricuspid valve leaflet and chordal detachment techniques provide equally viable and safe alternative to closure of hard-to-expose VSDs while maintaining appropriate TV function. Their use in our series did not lead to increased TV dysfunction at early-to-midterm echocardiographic assessment. Copyright © 2018. Published by Elsevier Inc.

A Structural Analysis of a Mechanical Heart Valve Prosthesis with Flat Leaflet

Science.gov (United States)

Kwon, Young Joo

This paper addresses the basic concept of MDO methodology and the structural analysis that should be performed in the design process of a mechanical heart valve prosthesis with flat leaflet using MDO methodology. In the structural design of the mechanical heart valve (MHV) prosthesis, the fluid mechanics analysis is executed for the blood flow passing through the leaflets of a mechanical heart valve prosthesis. Thereafter, the rigid body dynamics analysis of the leaflet motion is performed to obtain the structural condition for the structural mechanics analysis of the deformed leaflet. Then the structural mechanics analysis of the deformed leaflet follows to confirm the minimum thickness of the leaflet for the structural durability of the mechanical heart valve prosthesis. This paper shows that the minimum leaflet thickness can be evaluated to be 0.6mm among the suggested thicknesses.

The aim of this study was to validate the 2D computational fluid dynamics (CFD) results of a moving heart valve based on a fluid-structure interaction (FSI) algorithm with experimental measurements. Firstly, a pulsatile laminar flow through a monoleaflet valve model with a stiff leaflet was visualized by means of Particle Image Velocimetry (PIV). The inflow data sets were applied to a CFD simulation including blood-leaflet interaction. The measurement section with a fixed leaflet was enclosed into a standard mock loop in series with a Harvard Apparatus Pulsatile Blood Pump, a compliance chamber and a reservoir. Standard 2D PIV measurements were made at a frequency of 60 bpm. Average velocity magnitude results of 36 phase-locked measurements were evaluated at every 10 degrees of the pump cycle. For the CFD flow simulation, a commercially available package from Fluent Inc. was used in combination with inhouse developed FSI code based on the Arbitrary Lagrangian-Eulerian (ALE) method. Then the CFD code was applied to the leaflet to quantify the shear stress on it. Generally, the CFD results are in agreement with the PIV evaluated data in major flow regions, thereby validating the FSI simulation of a monoleaflet valve with a flexible leaflet. The applicability of the new CFD code for quantifying the shear stress on a flexible leaflet is thus demonstrated.

Transcatheter heart valve (THV) thrombosis has been increasingly reported. In these studies, thrombus quantification has been based on a 2-dimensional assessment of a 3-dimensional phenomenon. Postprocedural, 4-dimensional, volume-rendered CT data of patients with CoreValve, Evolut R, and SAPIEN 3 transcatheter aortic valve replacement enrolled in the RESOLVE study (Assessment of Transcatheter and Surgical Aortic Bioprosthetic Valve Dysfunction With Multimodality Imaging and Its Treatment with Anticoagulation) were included in this analysis. Patients on anticoagulation were excluded. SAPIEN 3 and CoreValve/Evolut R patients with and without hypoattenuated leaflet thickening were included to study differences between groups. Patients were classified as having THV thrombosis if there was any evidence of hypoattenuated leaflet thickening. Anatomic and THV deployment geometries were analyzed, and thrombus volumes were computed through manual 3-dimensional reconstruction. We aimed to identify and evaluate risk factors that contribute to THV thrombosis through the combination of retrospective clinical data analysis and in vitro imaging in the space between the native and THV leaflets (neosinus). SAPIEN 3 valves with leaflet thrombosis were on average 10% further expanded (by diameter) than those without (95.5±5.2% versus 85.4±3.9%; P <0.001). However, this relationship was not evident with the CoreValve/Evolut R. In CoreValve/Evolut Rs with thrombosis, the thrombus volume increased linearly with implant depth ( R 2 =0.7, P <0.001). This finding was not seen in the SAPIEN 3. The in vitro analysis showed that a supraannular THV deployment resulted in a nearly 7-fold decrease in stagnation zone size (velocities <0.1 m/s) when compared with an intraannular deployment. In addition, the in vitro model indicated that the size of the stagnation zone increased as cardiac output decreased. Although transcatheter aortic valve replacement thrombosis is a multifactorial process

Crutches, confetti or useful tools? Professionals' views on and use of health education leaflets.

This paper examines the views on and use of health education leaflets by a number of professional groups: health visitors, midwives, occupational health workers, pharmacists and school health education co-ordinators. Eighty nine percent currently obtain leaflets from health promotion units, with the exception of health visitors, professionals are largely satisfied with the units' service. Seventy six percent use commercial or sponsored leaflets primarily because of the large numbers and topics that are available. The numbers and type of leaflets used were found to vary across the professions. All professionals see an increasingly important role for leaflets in their work. A number of them, pharmacists and occupational health workers in particular, saw the numbers they use rising. These views were accompanied by lower levels of belief in a leaflets ability to increase knowledge and behaviour as well as lower levels of satisfaction with current leaflet use and a concern over the public's reception of leaflets. Methods of leaflet distribution to the public largely reflect the professionals' work contexts. Most popular were handing out leaflets with advice, leaving them in a public place and using them as a back-up to a meeting. A number of contradictions emerge between distribution practices and perceived effectiveness. Few professionals thought leaving leaflets in a public place was effective, and few health visitors and midwives believed giving leaflets to the family of a client was effective despite large numbers doing so. The implications of these findings for health promotion policy and practice are discussed.

The shape and formation of transmitral vortex ring are shown to be associated with diastolic function of the left ventricle (LV). Transmitral vortex ring is a flow feature that is observed to be non-axisymmetric in a healthy heart and its inherent asymmetry in the LV assists in efficient ejection of the blood during systole. This study is a first step towards understanding the effects of the mitral valve's anterior leaflet on transmitral flow. We experimentally study a single-leaflet model of the mitral valve to investigate the effect of the anterior leaflet on the axisymmetry of the generated vortex ring based on the three-dimensional data acquired using defocusing digital particle image velocimetry. Vortex rings form downstream of a D-shaped orifice in presence or absence of the anterior leaflet in various physiological stroke ratios. The results of the statistical analysis indicate that the formed vortex ring downstream of a D-shaped orifice is markedly non-axisymmetric, and presence of the anterior leaflet improves the ring's axisymmetry. This study suggests that the improvement of axisymmetry in presence of the anterior leaflet might be due to coupled dynamic interaction between rolling-up of the shear layer at the edges of the D-shaped orifice and the borders of the anterior leaflet. This interaction can reduce the non-uniformity in vorticity generation, which results in more axisymmetric behavior compared to the D-shaped orifice without the anterior leaflet.

Full Text Available OBJECTIVE - To analyze the immediate and late results of mitral valve repair with quadrangular resection of the posterior leaflet without the use of a prosthetic ring annuloplasty. METHODS - Using this technique, 118 patients with mitral valve prolapse who underwent mitral repair from January '84 through December '96 were studied. Age ranged from 30 to 86 (mean = 59.1±11.8 years and 62.7% were males. An associated surgery was performed in 22% of the patients, and coronary artery bypass graft was the most frequently performed surgery (15 patients - 12.7%. In 20 (16.9% patients other associated techniques of mitral valve repair were used and shortening of elongated chordae tendineae was the most frequent one (6 patients. RESULTS - Immediate mortality was 0.9% (one patient. Long-term rates for thromboembolism, endocarditis, re-operation and death in the late postoperative period were 0.4%, 0.4%, 1.7% and 2.2% patients/year, respectively. The actuarial curve of survival was 83.8±8.6% over 12 years; survival free from re-operation was 91.8±4.3%, free from endocarditis was 99.2±0.8% and free from thromboembolism was 99.2±0.8%. In the late postoperative period, 93.8% of the patients were in functional class 1 (NYHA, with a complete follow-up in 89.7% of the patients. CONCLUSION - Patients with mitral valve prolapse who undergo mitral valve repair using this technique have a satisfactory prognosis over 12 years.

Mitral valve interstitial cells (MVIC) play an important role in the pathogenesis of degenerative mitral regurgitation (MR) due to mitral valve prolapse (MVP). Numerous clinical studies have observed serotonin (5HT) dysregulation in cardiac valvulopathies; however, the impact of 5HT-mediated signaling on MVIC activation and leaflet remodeling in MVP have been investigated to a limited extent. Here we test the hypothesis that 5HT receptors (5HTRs) signaling contributes to MVP pathophysiology. Diseased human MV leaflets were obtained during cardiac surgery for MVP; normal MV leaflets were obtained from heart transplants. MV RNA was used for microarray analysis of MVP patients versus control, highlighting genes that indicate the involvement of 5HTR pathways and extracellular matrix remodeling in MVP. Human MV leaflets were also studied in vitro and ex vivo with biomechanical testing to assess remodeling in the presence of a 5HTR2B antagonist (LY272015). MVP leaflets from Cavalier King Charles Spaniels were used as a naturally acquired in vivo model of MVP. These canine MVP leaflets (N=5/group) showed 5HTR2B upregulation. This study also utilized CB57.1ML/6 mice in order to determine the effect of Angiotensin II infusion on MV remodeling. Histological analysis showed that MV thickening due to chronic Angiotensin II remodeling is mitigated by a 5HTR2B antagonist (LY272015) but not by 5HTR2A inhibitors. In humans, MVP is associated with an upregulation in 5HTR2B expression and increased 5HT receptor signaling in the leaflets. Antagonism of 5HTR2B mitigates MVIC activation in vitro and MV remodeling in vivo. These observations support the view that 5HTR signaling is involved not only in previously reported 5HT-related valvulopathies, but it is also involved in the pathological remodeling of MVP.

Abbasi, Mostafa; Azadani, Ali N

2017-07-01

In order to accommodate transcatheter valves to miniaturized catheters, the leaflet thickness must be reduced to a value which is typically less than that of surgical bioprostheses. The study aim was to use finite-element simulations to determine the impact of the thickness reduction on stress and strain distribution. A 23 mm transcatheter aortic valve (TAV) was modelled based on the Edwards SAPIEN XT (Edwards Lifesciences, Irvine, CA, USA). Finite-element (FE) analysis was performed using the ABAQUS/Explicit solver. An ensemble-averaged transvalvular pressure waveform measured from in-vitro tests conducted in a pulse duplicator was applied to the leaflets. Through a parametric study, uniform TAV leaflet thickness was reduced from 0.5 to 0.18 mm. By reducing leaflet thickness, significantly higher stress values were found in the leaflet's fixed edge during systole, and in the commissures during diastole. Through dynamic FE simulations, the highest stress values were found during systole in the leaflet fixed edge. In contrast, at the peak of diastole high-stress regions were mainly observed in the commissures. The peak stress was increased by 178% and 507% within the leaflets after reducing the thickness of 0.5 mm to 0.18 mm at the peak of systole and diastole, respectively. The study results indicated that, the smaller the leaflet thickness, the higher the maximum principal stress. Increased mechanical stress on TAV leaflets may lead to accelerated tissue degeneration. By using a thinner leaflet, TAV durability may not atch with that of surgical bioprostheses.

Counseling patients with written materials relies equally on patients' health literacy to understand their disease and its treatment, and the written materials' effectiveness communicating clearly in accessible and actionable ways. Only about 12% of the US population is adequately health literate. To explore the impact of reducing the health literacy demands of written patient health information. 805 patients were screened for health literacy, and recruited for balanced cohorts of adequate and low literacy, and high and normal blood pressure. Half of each patient cohort received either standard or "health literacy-friendly" drug summaries (i.e. Patient Package Inserts, or PPIs or "leaflets") along with a standardized health literacy assessment scale. The literacy-friendly drug summary improved comprehension of drug-related information overall from 50% to 71% correct responses. Adequate literacy patients improved from 58% correct to 90%, while lower literacy patients improved from 42% to 52% correct in response to the health literacy-friendly PPIs. Health literacy demands require special attention in developing and using written drug summary materials. Additionally, pharmacists should be provided additional information and counseling support materials to facilitate communications with low health literacy level patients.

Diabetes therapeutic education and information by leaflets is important. This study aimed to understand the effectiveness of written information to diabetic patients, after six months, in the control of diabetes and medication adherence. Non-pharmacological clinical trial. Randomized sample of diabetic patients of 65 volunteer doctors, distributed among the five health regions in Portugal. At the first appointment, patients were randomized in four groups (three intervention with validated leaflets and one control), leaflet reading being reinforced at the follow-up appointments in a 6-months period. Variables collected: HbA1c, home blood glucose, weight, waist circumference, blood pressure, cigarettes smoked, physical activity level, adherence to medication, medication, height, diabetes progression, age, sex and educational background. Descriptive and inferential statistics. From the 709 patients recruited, 702 were studied in this 6-months period with no statistical differences in the baseline variables studied. After six months of intervention, the adherence to medication improved in the leaflet group (p=0.034). This was noticed in those under 65 years of age (p=0.027), with diabetes for ≤ 5 years (p=0.010), with educational background up to 4 years (p=0.030) and 9 years (p=0.006) and with HbA1c ≥ 7% at the beginning of the study. Interventions with leaflets handed in primary healthcare to people with diabetes type 2 can bring benefits in what concerns adherence to therapeutics, namely in younger people with a less studies.

Patient education forms a cornerstone of management of inflammatory bowel disease (IBD). The Internet has opened new avenues for information gathering. To determine the relationship between different information sources and patient knowledge and anxiety in patients with IBD. The use of information sources in patients with IBD was examined via questionnaire. Anxiety was assessed with the hospital anxiety and depression scale and disease-related patient knowledge with the Crohn's and colitis knowledge score questionnaires. Associations between these outcomes and demographics, disease-related factors, and use of different information sources were analysed using linear regression analysis. Of 307 patients (165 Crohn's disease, 142 ulcerative colitis) 60.6% were female. Participants used the hospital IBD team (82.3%), official leaflets (59.5%), and official websites (53.5%) most frequently in contrast to alternative health websites (9%). University education (P sex (P = 0.004), clinically active disease (P sources are associated with better knowledge or worse anxiety levels. Face-to-face education and written information materials remain the first line of patient education. Patients should be guided towards official information websites and warned about the association between the use of alternative health websites or random links and anxiety. © 2016 John Wiley & Sons Ltd.

The early recognition of technology together with great ability to use computers and smart systems have promoted researchers to investigate the possibilities of utilizing technology for improving health care in children. The aim of this study was to compare between the traditional educational leaflets and E-applications in improving oral health knowledge, oral hygiene and gingival health in schoolchildren of Damascus city, Syria. A clustered randomized controlled trial at two public primary schools was performed. About 220 schoolchildren aged 10-11 years were included in this study and grouped into two clusters. Children in Leaflet cluster received oral health education through leaflets, while children in E-learning cluster received oral health education through an E-learning program. A questionnaire was designed to register information related to oral health knowledge and to record Plaque and Gingival indices. Questionnaire administration and clinical assessment were undertaken at baseline, 6 and at 12 weeks of oral health education. Data was analysed using one way repeated measures ANOVA, post hoc Bonferroni test and independent samples t-test. Leaflet cluster (107 participants) had statistically significant better oral health knowledge than E-learning cluster (104 participants) at 6 weeks (P E-learning cluster:100 participants). The mean knowledge gain compared to baseline was higher in Leaflet cluster than in E-learning cluster. A significant reduction in the PI means at 6 weeks and 12 weeks was observed in both clusters (P E-learning cluster at 6 weeks (P E-learning cluster at 6 weeks (P < 0.05) and 12 weeks (P < 0.05). Traditional educational leaflets are an effective tool in the improvement of both oral health knowledge as well as clinical indices of oral hygiene and care among Syrian children. Leaflets can be used in school-based oral health education for a positive outcome. Australian New Zealand Clinical Trials Registry ( ACTRN

The aim of this paper was to develop a new self-expandable aortic valved stent following the shape of the sinus of Valsalva, which can be deployed above native leaflets for aortic regurgitation, and study it's effect on coronary artery flow when orthotopic implantation in and above native leaflets. New self-expandable aortic valved stent consist of nitinol stent and bovine pericardium, and was designed following the shape of the sinus of Valsalva, the bovine pericardium was tailed as native leaflet. Thirty-six swine hearts were divided into three equal groups of twelve. In Group A (N.=12), the new self-expandable aortic valved stents deployed in native leaflets. In Group B (N.=12), the new self-expandable aortic valved stents deployed above native leaflets. In Group C (N.=12), the cylinder-like valved stents deployed only in native leaflets. The measurements of each coronary flow rate and endoscopic inspections were repeated post-implantation. In Group A and C, valve implantation in native leaflets resulted in a significant decrease in both left and right coronary flows. In Group B, no significant change in either right or left coronary flow was found after new self-expandable aortic valved stent placement. Endoscopic inspections showed that in group A and C the native leaflets sandwiched between valved stent and aortic wall, whereas, in group B the native leaflets were under the artificial leaflets. Two kinds of stents deployed in native leaflets affect left and right coronary flows significantly. No significant effect was found when the new self-expandable aortic valved stent deployed above native leaflets. This new self-expandable aortic valved stent can be deployed above the native leaflets, which avoids the obstruction of native leaflets on coronary flow.

Full Text Available Abstract Background While full disclosure of information on placebo control in participant information leaflets (PILs in a clinical trial is ethically required during informed consent, there have been concerning voices such complete disclosures may increase unnecessary nocebo responses, breach double-blind designs, and/or affect direction of trial outcomes. Taking an example of acupuncture studies, we aimed to examine what participants are told about placebo controls in randomized, placebo-controlled trials, and how it may affect blinding and trial outcomes. Methods Authors of published randomized, placebo-controlled trials of acupuncture were identified from PubMed search and invited to provide PILs for their trials. The collected PILs were subjected to content analysis and categorized based on degree of information disclosure on placebo. Blinding index (BI as a chance-corrected measurement of blinding was calculated and its association with different information disclosure was examined. The impact of different information disclosure from PILs on primary outcomes was estimated using a random effects model. Results In 65 collected PILs, approximately 57% of trials fully informed the participants of placebo control, i.e. full disclosure, while the rest gave deceitful or no information on placebo, i.e. no disclosure. Placebo groups in the studies with no disclosure tended to make more opposite guesses on the type of received intervention than those with disclosure, which may reflect wishful thinking (BI −0.21 vs. −0.16; p = 0.38. In outcome analysis, studies with no disclosure significantly favored acupuncture than those with full disclosure (standardized mean difference − 0.43 vs. −0.12; p = 0.03, probably due to enhanced expectations. Conclusions How participants are told about placebos can be another potential factor that may influence participant blinding and study outcomes by possibly modulating patient expectation. As we

To assess patients' opinion toward receiving written or specialized verbal pharmacists' interventions and to determine the effect of these interventions on patients' medication knowledge. 150 newly diagnosed patients with unipolar depression and initiated with a single antidepressant were randomized into 3 groups: control, leaflet and counselling, and interviewed at initiation and after 6-8 weeks of treatment at the outpatient department of the Psychiatric Hospital in Kuwait. 50% of respondents asserted that clinicians did not give them sufficient information while 90% favoured the idea of receiving further information about therapy. Forty seven percent of participants failed to return for the second follow-up appointment. The drop-out rate was 66% in the control, 42% in the Leaflet and only 34% in the counselling groups (P=0.004). A broad support for receiving leaflets and drug counselling (97%) was found among attendees. Moreover, 94% of the counselling and 79% of the leaflets group affirmed that they received adequate information compared to 47% of the control (P=0.001). Counselling was found to be significantly associated with a much higher recall of medicine name (OR=9.6, P=0.01), how to manage missed doses (OR=8.9, P=0.007), and correct use of medication (OR=31.3, Peducational material. However, both interventions were more informative than the control in conveying elemental drug information to patients. In contrast with the lack of enthusiasm that some clinicians express, the affirmativeness that was expressed by patients towards receiving written or verbal specialized educational interventions by pharmacists may support the psychiatric hospital pharmacists' stands in providing them for all patients which may aid in improving patients compliance and probably treatment outcome.

We treated a 61-year-old woman with mitral stenosis caused by pannus formation after Duran ring annuloplasty. Pannus overgrowth on the ring with extension onto both leaflets narrowed the mitral orifice and severely restricted the mobility of the valve leaflets. Mitral valve replacement with a St. Jude Medical mechanical heart valve prosthesis was successfully performed, and the postoperative course was uneventful. Patients undergoing Duran ring annuloplasty should be followed up with the consideration of possible mitral stenosis caused by pannus extension, as the cause for pannus formation remains unclear.

The extracellular matrix (ECM) plays crucial role in defining mechanical properties of a heart valve yet the mechanobiological role of the ECM proteins - collagen and elastin - in living heart valve leaflets is still poorly understood. In this study, non-linear microscopy was used to obtain three dimensional images of collagen and elastin arrangement in aortic leaflets under combined steady flow (850 ml/min) and cyclic flexure (1 Hz) mechanical (dynamic) training. A novel bioreactor capable of mimicking the flow conditions in a living heart was used in this study and was optimized for microscopic imagery. A custom made non-linear microscope was used in this study to provide Second Harmonic Generation (SHG) imaging of collagen arrangement and two-photon imaging of elastin. Two control and three trained leaflet samples from static and dynamic tissue culture were imaged to observe protein changes in the tissue for a period of seven days. Dynamic training led to a decrease in alignment index of the protein fibers compared to the static treatment.

To assess the acceptability for use of information on osteomalacia for South Asian patients. Ten focus groups of South Asian persons speaking Bengali, Gujarati, Hindi, Punjabi and Urdu (one male and one female group for each language) were used to evaluate the written (leaflets) and spoken information (CD) on osteomalacia for South Asian patients produced by the Arthritis Research Campaign (ARC). Focus group discussion was facilitated by community-based workers using the Social Action Research Method. A subsidiary evaluation of the information was conducted by a questionnaire-based survey sent to British Society of Rheumatology/British Health Professionals in Rheumatology (BSR/BHPR) members and others who had requested such materials from ARC in the past. Evaluation by focus groups revealed that there were potential difficulties relating to the understanding of the information leaflets and CDs and problematic issues regarding the quality of translation and pronunciation. Evaluation by BSR/BHPR members and others who had requested such material was that although the information was culturally appropriate, there were some weak areas such as mispronunciation, the quality of translation and specific customs. Healthcare information resources for minority ethnic groups has traditionally been developed depending upon the needs of the community, the language spoken and cultural norms. Such information is regarded as 'culturally sensitive'. However, an additional dimension is required. Information should be evaluated by the community and also specific users in order to determine its acceptability. This test of 'cultural competence' can ensure that such information has real practical value. An iterative evaluation process with feedback and refinement of information resources for minority ethnic groups is essential.

Tools to measure transmembrane-protein diffusion in lipid bilayer membranes have advanced in recent decades, providing a need for predictive theoretical models that account for interleaflet leaflet friction on tracer mobility. Here we address the fully three-dimensional flows driven by a (nonprotruding) transmembrane protein embedded in a dual-leaflet membrane that is supported above and below by soft porous supports (e.g., hydrogel or extracellular matrix), each of which has a prescribed permeability and solvent viscosity. For asymmetric configurations, i.e., supports with contrasting permeability, as realized for cells in contact with hydrogel scaffolds or culture media, the diffusion coefficient can reflect interleaflet friction. Reasonable approximations, for sufficiently large tracers on low-permeability supports, are furnished by a recent phenomenological theory from the literature. Interpreting literature data, albeit for hard-supported membranes, provides a theoretical basis for the phenomenological Stokes drag law as well as strengthening assertions that nonhydrodynamic interactions are important in supported bilayer systems, possibly leading to overestimates of the membrane/leaflet viscosity. Our theory provides a theoretical foundation for future experimental studies of tracer diffusion in gel-supported membranes.

[Readability and internet accessibility of informative documents for spinal cord injury patients in Spanish].

Patients with spinal cord injuries and their carers have access to leaflets on Internet that they can use as educational material to complement traditional forms of education. The aim of this study is to evaluate the readability of informative documents in Spanish, obtained from Internet and aimed at patients with spinal cord injuries. A search was made with the Google search engine using the following key words: recommendation, advice, guide, manual, self-care, education and information, adding spinal cord injury, paraplegia and tetraplegia to each of the terms. We analyzed the first 50 results of each search. The readability of the leaflets was studied with the Flesch-Szigriszt index and the INFLESZ scale, both available on the INFLESZ program. Also indicated were year of publication, country and number of authors of the documents obtained. We obtained 16 documents, developed between 2001 and 2011. Readability oscillated between 43.34 (some-what difficult) and 62 (normal), with an average value of 51.56 (somewhat difficult). Only 4 pamphlets (25%) showed a Flesch-Szigriszt index of ≥ 55 (normal). There was no difference in readability by year, authors or country of publication. The readability of 75% of the documents studied was "somewhat difficult" according to the INFLESZ scale. These results coincide with previous studies, in both Spanish and English. If the readability of this type of documents is improved, it will be easier to achieve their educational goal.

The enigmatic fast leaflet rotation in Desmodium motorium

Lev-Yadun, Simcha

2013-01-01

I propose that the enigmatic leaflet movements in elliptical circles every few minutes of the Indian telegraph (semaphore) plant Desmodium motorium ( = D. gyrans = Hedysarum gyrans = Codariocalyx motorius), which has intrigued scientists for centuries, is a new type of butterfly or general winged arthropod mimicry by this plant. Such leaflet movement may deceive a passing butterfly searching for an un-occupied site suitable to deposit its eggs, that the plant is already occupied. It may also attract insectivorous birds, reptiles or arthropods to the plant because it looks as if it is harboring a potential prey and while they patrol there, they can find insects or other invertebrates that indeed attack the plant. The possibility that diurnal mammalian herbivores may also be deterred by these movements should not be dismissed. PMID:23603964

A Coarse Grained Model for a Lipid Membrane with Physiological Composition and Leaflet Asymmetry.

Directory of Open Access Journals (Sweden)

Satyan Sharma

Full Text Available The resemblance of lipid membrane models to physiological membranes determines how well molecular dynamics (MD simulations imitate the dynamic behavior of cell membranes and membrane proteins. Physiological lipid membranes are composed of multiple types of phospholipids, and the leaflet compositions are generally asymmetric. Here we describe an approach for self-assembly of a Coarse-Grained (CG membrane model with physiological composition and leaflet asymmetry using the MARTINI force field. An initial set-up of two boxes with different types of lipids according to the leaflet asymmetry of mammalian cell membranes stacked with 0.5 nm overlap, reliably resulted in the self-assembly of bilayer membranes with leaflet asymmetry resembling that of physiological mammalian cell membranes. Self-assembly in the presence of a fragment of the plasma membrane protein syntaxin 1A led to spontaneous specific positioning of phosphatidylionositol(4,5bisphosphate at a positively charged stretch of syntaxin consistent with experimental data. An analogous approach choosing an initial set-up with two concentric shells filled with different lipid types results in successful assembly of a spherical vesicle with asymmetric leaflet composition. Self-assembly of the vesicle in the presence of the synaptic vesicle protein synaptobrevin 2 revealed the correct position of the synaptobrevin transmembrane domain. This is the first CG MD method to form a membrane with physiological lipid composition as well as leaflet asymmetry by self-assembly and will enable unbiased studies of the incorporation and dynamics of membrane proteins in more realistic CG membrane models.

Full Text Available Valve perforation complicating infective endocarditis has been for decades a bad sign leading to severe valve destruction, intractable heart failure and even death if surgical therapy is not administered in time. Here we present a 57 years old male patient inadvertently diagnosed with pneumonia and chronic obstructive pulmonary disease exacerbation in another hospital. After 20 days of broad spectrum antibiotics and bronchodilator therapy no improvement was achieved. During examination a severe aortic regurgitation was recognized. Immediately after, patient was transferred to our hospital for aortic valve surgery evaluation. Transthorasic echocardiography (TTE showed a severe aortic regurgitation and vegetation like echogenicity over the noncoronary leaflet. An aortic valve replacement surgical therapy was decided. During the aortic valve excision underneath the vegetations, multiple small perforations in all the three leaflets were noticed. The destructed valve was excised and a mechanical aortic prosthesis (St Jude No: 23, MN, USA was successfully replaced. After 14 days of treatment patient was healthily discharged.

Outcomes of tricuspid valve replacement are poor, partly due to right heart remodelling. The research on its underlying mechanisms is hampered by a lack of animal models of tricuspid regurgitation (TR). Our objective was to create a reproducible and clinically compatible TR animal model to study right heart remodelling caused by TR. Fourteen juvenile male Beagle dogs were divided randomly into an intervention group (n = 11) and a sham-operated control group (n = 3). The intervention group underwent thoracotomy and right atrial incision following superior and inferior vena caval occlusion. The anterior leaflet, together with the chordae, of the tricuspid valve was resected in eight dogs ('one leaflet' group), whereas both anterior and posterior leaflets, together with the chordae, were resected in three dogs ('two leaflets' group). The right atrium and chest were then closed. The control group underwent the same procedure, except leaflet resection. One dog from the 'two leaflets' group and one control dog were sacrificed and autopsy was performed at 12 months post-surgery. All dogs survived over the 1-year observation period postoperatively. TR grade IV occurred immediately postoperatively in the 'one leaflet' group, and TR grade IV plus in the 'two leaflets' group. The overall procedure lasted 30-40 min, and the mean time of vena caval occlusion was 87 ± 10 s. Central venous pressure increased from 6 ± 1.2 at baseline to 13 ± 1.7 mmHg (P heart remodelling. © The Author 2015.

A study of the pulsatile flow and its interaction with rectangular leaflets

Ledesma, Rene; Zenit, Roberto; Pulos, Guillermo

2009-11-01

To avoid the complexity and limited understanding of the 3D pulsatile flow field through heart valves, a cardiac-like flow circuit and a test channel were designed to study the behavior of bidimensional leaflets made of hyperelastic materials. We study a simple 2D arrangement to understand the basic physics of the flow-leaflet interaction. Creating a periodic pressure gradient, measurements of leaflet deflection were obtained for different flow conditions, geometries and materials. Using PIV and Phase Locking techniques, we have obtained the leaflet motion and the time-dependent flow velocity fields. The results show that two dimensionless parameters determine the performance of a simple bi-dimensional valve, in accordance with the flow conditions applied: π1=f(sw)^1/2(E/ρ)^1/2 and π2=V/(2slw), where f is the pulsation frequency, V is the stroke volume, s, w and l are the dimensions on the leaftlet and E and ρ are the elastic modulus and density of the material, respectively. Furthermore, we have identified the conditions for which the fluid stresses can be minimized. With these results we propose a new set of parameters to improve the performance of prosthetic heart valves and, in consequence, to reduce blood damage.

Improving mobility in elderly persons is a primary goal in geriatric rehabilitation. Self-regulated exercises with instruction leaflets are used to increase training volume but adherence is often low. Exergames may improve adherence. This study therefore compared exergames with self-regulated exercise using instruction leaflets. The primary outcome was adherence. Secondary outcomes were enjoyment, motivation and balance during walking. Design: single center parallel group non-blinded randomized controlled trial with central stratified randomization. center for geriatric inpatient rehabilitation. Included were patients over 65 with mobility restrictions who were able to perform self-regulated exercise. Patients were assigned to self-regulated exercise using a) exergames on Windows Kinect® (exergame group EG) or b) instruction leaflets (conventional group CG). During two 30 min sessions physical therapists instructed self-regulated exercise to be conducted twice daily during thirty minutes during ten working days. Patients reported adherence (primary outcome), enjoyment and motivation daily. Balance during walking was measured blind before and after the treatment phase with an accelerometer. Analysis was by intention to treat. Repeated measures mixed models and Cohen's d effect sizes (ES, moderate if >0.5, large if > 0.8) with 95% CIs were used to evaluate between-group effects over time. Alpha was set at 0.05. From June 2014 to December 2015 217 patients were evaluated and 54 included, 26 in the EG and 28 in the CG. Adverse effects were observed in two patients in the EG who stopped because of pain during exercising. Adherence was comparable at day one (38 min. in the EG and 42 min. in the CG) and significantly higher in the CG at day 10 (54 min. in the CG while decreasing to 28 min. in the EG, p = 0.007, ES 0.94, 0.39-0.151). Benefits favoring the CG were also observed for enjoyment (p = 0.001, ES 0.88, 0.32 - 1.44) and motivation (p = 0

Bactris gasipaes is widely cultivated for the consumption of palm hearts and fruits. The present work describes the micro morphological characteristics of leaflets from adult plants of B. gasipaes, thornless variety Diamantes-10, collected in the Diamantes Experimental Station in Guápiles, Costa Rica. We collected 25 leaflets and analyses were performed with a combination of microscopy techniques: light microscopy, scanning electron microscopy and transmission electron microscopy to study their structure. Our results showed that leaflets have abundant epicuticular wax on adaxial and abaxial surfaces. Analyses from the epidermis indicated that it is composed of isodiametric cells, and it is also evident that hypodermis cells have rectangular shape and are larger than the other epidermal cells. We observed stomata on both surfaces, but they were more abundant in the abaxial surface. On the other hand, the epidermis showed the presence of trichomes with three different morphologies. In the parenchyma, cells are large and not well defined, and we observed the presence of astroesclereids, and compact groups of fiber bundles between parenchyma cells. The central vein has several vascular bundles, arranged in a continuous manner, and they are surrounded by sclerotic tissue; some of these fibers presented live protoplasts. All minor veins showed the same anatomy as the central vein. In these veins, the vessel elements of protoxylem and metaxylem showed scalariform ornaments on their walls. Phloem is located towards the adaxial surface of the vein and we observed sieve and companion cells surrounded by fibers and parenchyma cells. The companion cells presented branched plasmodesmata attached to a sieve element, and in these elements we found protein bodies called P-protein. The main anatomical difference in the leaflets of the var. Diamantes-10, compared to the other varieties of B. gasipaes K, is the lack of thorns; the other morphological features seem to be conserved.

Our understanding of membranes and membrane lipid function has lagged far behind that of nucleic acids and proteins, largely because it is difficult to manipulate cellular membrane lipid composition. To help solve this problem, we show that methyl-α-cyclodextrin (MαCD)-catalyzed lipid exchange can be used to maximally replace the sphingolipids and phospholipids in the outer leaflet of the plasma membrane of living mammalian cells with exogenous lipids, including unnatural lipids. In addition, lipid exchange experiments revealed that 70-80% of cell sphingomyelin resided in the plasma membrane outer leaflet; the asymmetry of metabolically active cells was similar to that previously defined for erythrocytes, as judged by outer leaflet lipid composition; and plasma membrane outer leaflet phosphatidylcholine had a significantly lower level of unsaturation than phosphatidylcholine in the remainder of the cell. The data also provided a rough estimate for the total cellular lipids residing in the plasma membrane (about half). In addition to such lipidomics applications, the exchange method should have wide potential for investigations of lipid function and modification of cellular behavior by modification of lipids.

A newly developed technique using ruthenium red to detect foci of bacterial digestion in mounts of whole leaflets that had been incubated with rumen bacteria was used to compare the digestion of alfalfa, a bloat-causing legume, and sainfoin, a bloat-safe legume. When whole leaflets were suspended in an artificial rumen medium and inoculated with rumen bacteria, massive bacterial adhesion and proliferation were noted at the stomata of alfalfa leaflets after 6 h of incubation, whereas only a few isolated bacteria adhered near the stomata of sainfoin leaflets After 22 h of incubation, the epidermal layers of alfalfa leaflets had peeled away in many areas, revealing an extensive bacterial invasion of the underlying mesophyll tissue in which large bacterial microcolonies had formed in intercellular spaces, and in intracellular spaces in several areas where plant cell walls had broken down. After 22 h of incubation, the surface of sainfoin leaflets resembled that of alfalfa leaflets at 6 h, with bacterial microcolonies adhering to the area surrounding the stomata, but without sloughing of the epidermis. Uninoculated control leaflets of both species showed no surface alteration but part of their normal bacterial flora had proliferated to form microcolonies on the surface after 22 h incubation. Dry matter loss due to leaching or bacterial digestion when whole leaflets of legumes were suspended in an artificial rumen medium, alone or with rumen bacteria, was significantly higher in the bloat-causing group. Values of leaching and of bacterial digestion were positively correlated. We conclude that reported differences in plant anatomy, and in cell wall chemistry, produce distinct rates or organic nutrient release from legume leaflets, and that these same differences produce an equally distinct susceptibility of leaflets to bacterial invasion, plant cell rupture, and the consequent release of intracellular plant components. The rate of release of organic nutrients from legume

Approval of the research proposal by an ethical review committee from both sponsoring and host countries is a generally agreed requirement in externally sponsored research.However, capacity for ethics review is not universal. Aim of this study was to identify opinions and views of the members serving in ethical review and ethics committees in Sri Lanka on informed consent, essential components in the information leaflet and the consent form. We obtained ethical approval from UK and Sri Lanka. A series of consensus generation meetings on the protocol were conducted. A task oriented interview guide was developed. The interview was based on open-ended questionnaire. Then the participants were given a WHO checklist on informed consent and requested to rate the items on a three point scale ranging from extremely important to not important. Twenty-nine members from ethics committees participated. Majority of participants (23), believed a copy of the information leaflet and consent form, should accompany research proposal. Opinions about the items that should be included in the information leaflets varied. Participants identified 18 criteria as requirements in the information leaflet and 19 for the consent form. The majority, 20 (69%), believed that all research need ethical approval but identified limited human resource, time and inadequate capacity as constraints. Fifteen (52%) believed that written consent is not required for all research. Verbal consent emerged as an alternative to written consent. The majority of participants rated all components of the WHO checklist as important. The number of themes generated for the consent form (N = 18) is as many as for the information leaflet (N = 19) and had several overlaps. This suggests that the consent form should be itemized to reflect the contents covered in the information leaflet. The participants' opinion on components of the information leaflets and consent forms proved to be similar with WHO checklist on informed

Full Text Available Date palm residues are one of the most promising lignocellulosic biomass for bioethanol production in the Middle East. In this study, leaflets and rachis were subjected to hydrothermal pretreatment to overcome the recalcitrance of the biomass for enzymatic conversion. Evident morphological, structural, and chemical changes were observed by scanning electron microscopy, X-ray diffraction, and infrared spectroscopy after pretreatment. High glucan (>90% for both leaflets and rachis and xylan (>75% for leaflets and >79% for rachis recovery were achieved. Under the optimal condition of hydrothermal pretreatment (210°C/10 min highly digestible (glucan convertibility, 100% to leaflets, 78% to rachis and fermentable (ethanol yield, 96% to leaflets, 80% to rachis solid fractions were obtained. Fermentability test of the liquid fractions proved that no considerable inhibitors to Saccharomyces cerevisiae were produced in hydrothermal pretreatment. Given the high sugar recovery, enzymatic digestibility, and ethanol yield, production of bioethanol by hydrothermal pretreatment could be a promising way of valorization of date palm residues in this region.

Biomechanical and ultrastructural comparison of cryopreservation and a novel cellular extraction of porcine aortic valve leaflets.

Heart valve substitutes of biological origin often fail by degenerative mechanisms. Many authors have hypothesized that mechanical fatigue and structural degradation are instrumental to in vivo failure. Since the properties of the structural matrix at implantation may predetermine failure, we have examined the ultrastructure, fracture, mechanics, and uniaxial high-strain-rate viscoelastic properties of: (1) fresh, (2) cryopreserved, and (3) cellular extracted porcine aortic valve leaflets. The cellular extraction process is being developed in order to reduce immunological attack and calcification. Cryopreservation causes cellular disruption and necrotic changes throughout the tissue, whereas extraction removes all cells and lipid membranes. Both processes leave an intact collagen and elastin structural matrix and preserve the high-strain-rate viscoelastic characteristics of the fresh leaflets. Extraction does cause a 20% reduction in the fracture tension and increases tissue extensibility, with the percent strain at fracture rising to 45.3 +/- 4 (mean +/- SEM) from 31.5 +/- 3 for fresh leaflets. However, extraction does preserve matrix structure and mechanics over the physiological loading range. Glutaraldehyde fixation produces increased extensibility, increased elastic behavior, and, when applied to extracted leaflets, it causes a marked drop in fracture tension, to 50% of that for fresh leaflets. The combination of extraction and fixation may lead to early degenerative failure. The cellular extraction technique alone may be a useful alternative to glutaraldehyde fixation in preparing bioprosthetic heart valves.

Humanising illness: presenting health information in educational comics.

2014-06-01

Research into the effectiveness of comic books as health education tools overwhelmingly consists of studies evaluating the information learnt as a result of reading the comic, for example using preintervention and postintervention questionnaires. In essence, these studies evaluate comics in the same way in which a patient information leaflet might be evaluated, but they fail to evaluate the narrative element of comics. Health information comics have the potential to do much more than simply convey facts about an illness; they can also support patients in dealing with the social and psychological aspects of a condition. This article discusses how some common elements of educational comics are handled in a selection of comics about diabetes, focusing on the more personal or social aspects of the condition as well as the presentation of factual information. The elements examined include: fears and anxieties; reactions of friends and family; interactions with medical professionals; self-management; and prevention. In conclusion, the article argues that comics, potentially, have many advantages over patient information leaflets, particularly in the way in which they can offer 'companionship', helping patients to address fears and negative feelings. However, empirical studies are required to evaluate educational comics in a way which takes account of their potential role in supporting patients in coming to terms with their condition, as well as becoming better informed.

The initial viability results were used and correlated to assess the effect of cause of death and the effect of time lapse between death and heart retrieval on the viability of the leaflet cells. It was found that there was no correlation between initial viability and viability following cryopreservation. Furthermore, there was no correlation between time passed after death before the hcart was removed and the cellular viability. The cause of death had no effect on the viability. Surgeons who were contacted for follow up of patients who had received valves from the Donor Tissue Bank of Victoria, reported that there were no differences in clinical outcome between patients receiving viable or non-viable valves

2018-05-01

In this work, two different designs of artificial heart valve were devised and then compared by considering the thrombosis, wear and valve orifice to anatomical orifice ratio of each mechanical heart valve. These different design configurations of bi-leaflet mechanical heart valves model are created through the use of Computer-aided design (CAD) modelling and simulated using Computational fluid dynamic (CFD) software. Design 1 is based on existing conventional bi-leaflet valve and design 2 based on modified bi-leaflet respectively. The flow pattern, velocity, vorticity and stress analysis have been done to justify the best design. Based on results, both of the designs show a Doppler velocity index of less than the allowable standard of 2.2 which is safe to be used as replacement of the human heart valve. However, design 2 shows that it has a lower possibility of cavitation issue which will lead to lower thrombosis and provide good central flow area of blood as compared to design 1.

Full Text Available Abstract Background Approval of the research proposal by an ethical review committee from both sponsoring and host countries is a generally agreed requirement in externally sponsored research. However, capacity for ethics review is not universal. Aim of this study was to identify opinions and views of the members serving in ethical review and ethics committees in Sri Lanka on informed consent, essential components in the information leaflet and the consent form. Methods We obtained ethical approval from UK and Sri Lanka. A series of consensus generation meetings on the protocol were conducted. A task oriented interview guide was developed. The interview was based on open-ended questionnaire. Then the participants were given a WHO checklist on informed consent and requested to rate the items on a three point scale ranging from extremely important to not important. Results Twenty-nine members from ethics committees participated. Majority of participants (23, believed a copy of the information leaflet and consent form, should accompany research proposal. Opinions about the items that should be included in the information leaflets varied. Participants identified 18 criteria as requirements in the information leaflet and 19 for the consent form. The majority, 20 (69%, believed that all research need ethical approval but identified limited human resource, time and inadequate capacity as constraints. Fifteen (52% believed that written consent is not required for all research. Verbal consent emerged as an alternative to written consent. The majority of participants rated all components of the WHO checklist as important. Conclusion The number of themes generated for the consent form (N = 18 is as many as for the information leaflet (N = 19 and had several overlaps. This suggests that the consent form should be itemized to reflect the contents covered in the information leaflet. The participants' opinion on components of the information leaflets and

The application of information technology in health education plan in Taiwan has existed for a long time. The purpose of this study is to explore the relationship between information technology application in health education and patients' preoperative knowledge by synthesizing existing researches that compare the effectiveness of information technology application and traditional instruction in the health education plan. In spite of claims regarding the potential benefits of using information technology in health education plan, results of previous researches were conflicting. This study is carried out to examine the effectiveness of information technology by using network meta-analysis, which is a statistical analysis of separate but similar studies in order to test the pooled data for statistical significance. Information technology application in health education discussed in this study include interactive technology therapy (person-computer), group interactive technology therapy (person-person), multimedia technology therapy and video therapy. The result has shown that group interactive technology therapy is the most effective, followed by interactive technology therapy. And these four therapies of information technology are all superior to the traditional health education plan (leaflet therapy).

The enigmatic fast leaflet rotation in Desmodium motorium: butterfly mimicry for defense?

Science.gov (United States)

Lev-Yadun, Simcha

2013-06-01

I propose that the enigmatic leaflet movements in elliptical circles every few minutes of the Indian telegraph (semaphore) plant Desmodium motorium ( = D. gyrans = Hedysarum gyrans = Codariocalyx motorius), which has intrigued scientists for centuries, is a new type of butterfly or general winged arthropod mimicry by this plant. Such leaflet movement may deceive a passing butterfly searching for an un-occupied site suitable to deposit its eggs, that the plant is already occupied. It may also attract insectivorous birds, reptiles or arthropods to the plant because it looks as if it is harboring a potential prey and while they patrol there, they can find insects or other invertebrates that indeed attack the plant. The possibility that diurnal mammalian herbivores may also be deterred by these movements should not be dismissed.

People living with complex regional pain syndrome (CRPS) experience frustration with the lack of knowledge and understanding of CRPS as a pain condition. We report on our attempt to address this issue. People living with CRPS taking part in a larger study were invited to co-construct a CRPS wiki page that addressed the areas in which they had experienced the most difficulty. A blank wiki page was set up for participants to populate with issues they felt needed to be raised and addressed. Participants failed to engage with the wiki technology. We modified our procedure and completed an inductive analysis of a sister-forum which participants were using as part of the larger study. Six issues of importance were identified. We used the discussion forum threads to populate the themes. Due to a continued lack of engagement with the wiki technology, the team decided to create a suite of leaflets which were piloted with delegates at a CRPS patient conference. Future work should be mindful of the extent to which patients are able and willing to share their experiences through such technology. Striking the balance between patient-endorsed and researcher-driven co-creation of such material is imperative.

The aim of this study was to assess current practices around obtaining consent for blood transfusion and provision of patient information in hospitals across the UK and identify areas for improvement. Recommendations from the Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) (2011) state that valid consent should be obtained for blood transfusion and documented in clinical records. A standardised source of information should be available to patients. Practices in relation to this have historically been inconsistent. The consent process was studied in hospitals across the UK over a 3-month period in 2014 by means of an audit of case notes and simultaneous surveys of patients and staff. In total, 2784 transfusion episodes were reviewed across 164 hospital sites. 85% of sites had a policy on consent for transfusion. Consent was documented in 43% of case notes. 68% of patients recalled being given information on benefits of transfusion, 38% on risks and 8% on alternatives and 28% reported receiving an information leaflet. In total, 85% of staff stated they had explained the reason for transfusion, but only 65% had documented this. 41% of staff had received training specifically on transfusion consent in the last 2 years. There is a need to improve clinical practice in obtaining valid consent for transfusion in line with existing national guidelines and local Trust policies, with emphasis on documentation within clinical records. Provision of patient information is an area particularly highlighted for action, and transfusion training for clinicians should be strengthened. © 2017 British Blood Transfusion Society.

To identify the most relevant aspects that guarantee the readability, clarity and simplicity of written health education materials. Delphi methodology in order to reach a state of consensus among health education experts on criteria of legibility in the design and publication of informative material and literature. Seventeen experts reached agreement on the principal recommendations for ensuring the legibility of health education materials. They were as follows: a) text content and layout: to structure the text using a title or subtitle, message explanation and conclusion; b) text construction: to use simple and concise sentences, diagrams and examples, and graphically highlighting the principal ideas; c) lexical comprehension: to use simple words and avoid technical language and abbreviations; d) typography: to use an easy-to-read font. There is a high degree of consensus regarding the way health education materials should be drawn up. This list of recommendations could be used as an instrument for reviewing and improving the design of health education materials. In general, it is recommended to identify the users of the leaflets and involve them in the writing and design.

Getting to the Outer Leaflet: Physiology of Phosphatidylserine Exposure at the Plasma Membrane.

Science.gov (United States)

Bevers, Edouard M; Williamson, Patrick L

2016-04-01

Phosphatidylserine (PS) is a major component of membrane bilayers whose change in distribution between inner and outer leaflets is an important physiological signal. Normally, members of the type IV P-type ATPases spend metabolic energy to create an asymmetric distribution of phospholipids between the two leaflets, with PS confined to the cytoplasmic membrane leaflet. On occasion, membrane enzymes, known as scramblases, are activated to facilitate transbilayer migration of lipids, including PS. Recently, two proteins required for such randomization have been identified: TMEM16F, a scramblase regulated by elevated intracellular Ca(2+), and XKR8, a caspase-sensitive protein required for PS exposure in apoptotic cells. Once exposed at the cell surface, PS regulates biochemical reactions involved in blood coagulation, and bone mineralization, and also regulates a variety of cell-cell interactions. Exposed on the surface of apoptotic cells, PS controls their recognition and engulfment by other cells. This process is exploited by parasites to invade their host, and in specialized form is used to maintain photoreceptors in the eye and modify synaptic connections in the brain. This review discusses what is known about the mechanism of PS exposure at the surface of the plasma membrane of cells, how actors in the extracellular milieu sense surface exposed PS, and how this recognition is translated to downstream consequences of PS exposure.

Real-time three-dimensional transesophageal echocardiography (RT3D-TEE) can provide unique visualization and better understanding of the relationship among cardiac structures. Here, we report the case of an 85-year-old woman with an obstructed mitral prosthetic valve diagnosed promptly by RT3D-TEE, which clearly showed a leaflet stuck in the closed position. The opening and closing angles of the valve leaflets measured by RT3D-TEE were compatible with those measured by fluoroscopy. Moreover, RT3D-TEE revealed, in the ring of the prosthetic valve, thrombi that were not visible on fluoroscopy. RT3D-TEE might be a valuable diagnostic technique for prosthetic mitral valve thrombosis. © 2014 Wiley Periodicals, Inc.

To continue with the implementation of the medication reconciliation process on admission, and to analyse potentially inappropriate prescriptions according to the STOPP-START -Screening Tool of Older Person's potentially inappropriate Prescriptions/Screening Tool to Alert doctors to the Right (indicated) Treatment- criteria, and drug interactions. To extend the process of reconciliation at hospital discharge from the Cardiology and Chest Diseases departments. Retrospective observational study that included patients over 75 years old. The "Consensus Document on Terminology and Classification in Medication Reconciliation" was used for the classification of the discrepancies found. Potentially inappropriate prescriptions and drug interactions were reviewed. For reconciliation at discharge, a "Drug information program at discharge" leaflet and a "Patient information sheet" was developed. The number of reconciled patients was 818, with a level of coverage of 42.3% (target patients: 1,932). Reconciliation errors by patient were 23.4% (191) on admission and 22.5% (9) at discharge. All patients who were reconciled at discharge were given the "Drug information program at discharge" leaflet. Potentially inappropriate prescriptions, according to STOPP/START criteria, affected 6.0% (49) of reconciled patients. The number of clinically relevant interactions affected 11.7% (96) of patients. The implementation of a reconciliation process has detected the existence of errors between chronic and prescribed treatment in the hospital. The STOPP/START criteria applied to this group of patients have helped to find out the most common potentially inappropriate prescriptions. The analysis of drug interactions shows drug combinations that should be avoided in these patients. Copyright © 2016 SECA. Published by Elsevier Espana. All rights reserved.

Detection of cholesterol-rich microdomains in the inner leaflet of the plasma membrane

International Nuclear Information System (INIS)

Hayashi, Masami; Shimada, Yukiko; Inomata, Mitsushi; Ohno-Iwashita, Yoshiko

2006-01-01

The C-terminal domain (D4) of perfringolysin O binds selectively to cholesterol in cholesterol-rich microdomains. To address the issue of whether cholesterol-rich microdomains exist in the inner leaflet of the plasma membrane, we expressed D4 as a fusion protein with EGFP in MEF cells. More than half of the EGFP-D4 expressed in stable cell clones was bound to membranes in raft fractions. Depletion of membrane cholesterol with β-cyclodextrin reduced the amount of EGFP-D4 localized in raft fractions, confirming EGFP-D4 binding to cholesterol-rich microdomains. Subfractionation of the raft fractions showed most of the EGFP-D4 bound to the plasma membrane rather than to intracellular membranes. Taken together, these results strongly suggest the existence of cholesterol-rich microdomains in the inner leaflet of the plasma membrane

The surface microstructure of cusps and leaflets in rabbit and mouse heart valves

Directory of Open Access Journals (Sweden)

Xia Ye

2014-05-01

Full Text Available In this investigation, scanning electron microscopy was used to characterize the microstructure on the surfaces of animal heart valve cusps/leaflets. The results showed that though these surfaces appear smooth to the naked eye, they are actually comprised of a double hierarchical structure consisting of a cobblestone-like microstructure and nano-cilia along with mastoids with a directional arrangement. Such nanostructures could play a very important role in the hemocompatibility characteristics of heart valves. On this basis, the model of the microstructure was constructed and theoretical analysis was used to obtain optimal geometric parameters for the rough surface of artificial valve cusps/leaflets. This model may help improve reconstructive techniques and it may be beneficial in the design and fabrication of valve substitutes or partial substitutes. Namely, the model may help ameliorate heart valve replacement surgery.

A numerical analysis on the curved bileaflet Mechanical Heart Valve (MHV) : leaflet motion and blood flow in an elastic blood vessel

International Nuclear Information System (INIS)

Bang, Jin Seok; Kim, Chang Nyung; Choi, Choeng Ryul

2005-01-01

In blood flow passing through the Mechanical Heart Valve (MHV) and elastic blood vessel, hemolysis and platelet activation causing thrombus formation can be seen owing to the shear stress in the blood. Also, fracture and deformation of leaflets can be observed depending on the shape and material properties of the leaflets which is opened and closed in a cycle. Hence, comprehensive study is needed on the hemodynamics which is associated with the motion of leaflet and elastic blood vessel in terms of fluid-structure interaction. In this paper, a numerical analysis has been performed for a three-dimensional pulsatile blood flow associated with the elastic blood vessel and curved bileaflet for multiple cycles in light of fluid-structure interaction. From this analysis fluttering phenomenon and rebound of the leaflet have been observed and recirculation and regurgitation have been found in the flow fields of the blood. Also, the pressure distribution and the radial displacement of the elastic blood vessel have been obtained. The motion of the leaflet and flow fields of the blood have shown similar tendency compared with the previous experiments carried out in other studies. The present study can contribute to the design methodology for the curved bileaflet mechanical heart valve. Furthermore, the proposed fluid-structure interaction method will be effectively used in various fields where the interaction between fluid flow and structure are involved

Government policy in the UK emphasises providing patients with good health information to encourage participation in their health care. Patient information leaflets (PILs) form part of this policy and have been shown to affect patient health outcomes; however, many are poorly written. To describe the PILs in general practice surgeries in Stoke-on-Trent in terms of readability and variety of content. An observational study of randomly selected GP practices (n = 17) across Stoke-on-Trent. PILs were assessed for readability (Flesch Reading Ease and Flesch-Kincaid Grade Level) and compared with national skills level data and with the recommended level for medical information. The PILs were also categorised for content using the Rudd (2007) health material classification framework. A total of 345 PILs were collected and assessed. Only 24.3% meet recommended reading-level criteria. Compared with national skills levels, over 75% of the PILs collected were too complex for at least 15% of the English population. Of the PILs, 47.8% were classified as 'systems navigation' (information regarding services); 22.9% were disease prevention (screening and immunisations); 14.2% personal and public safety; and less than 10% were for managing illness or health promotion. Current PILs in general practices do not all promote health literacy. Information only accessible to a proportion of higher skilled patients may increase inequalities in health. Less than 10% of PILs promote managing illness or healthy lifestyles. Processes must be put in place to improve the readability and variety of content of PILs in GP practices. © British Journal of General Practice 2015.

Traumatic tricuspid valve insufficiency. Experience in thirteen patients.

van Son, J A; Danielson, G K; Schaff, H V; Miller, F A

1994-11-01

From 1964 through June 1993, thirteen patients with traumatic tricuspid insufficiency were treated surgically; all were male, and the ages ranged from 17 to 64 years (median 39 years). The condition was associated with blunt chest trauma in all patients: motor vehicle accidents in twelve and an explosion of a tank of compressed air in one. The median duration between trauma and operation was 17 years (range 1 month to 37 years). Preoperatively, six patients were in sinus rhythm and seven were in atrial fibrillation. At operation, the right ventricular function appeared moderately to severely depressed in twelve patients. In twelve patients, the anterior leaflet was flail because of chordal rupture (n = 9), rupture of anterior papillary muscle (n = 3), or tear in the anterior leaflet (n = 1). In one patient, the septal leaflet was missing and in another it was retracted and adherent to the ventricular septum. In five patients the tricuspid valve was repaired and in eight it was replaced. In seven patients in the latter group, the chordae, papillary muscles, and/or tricuspid valve leaflet(s) were found to be in a contracted and atrophic state, precluding repair. No early or late deaths occurred. At follow-up extending to 26 years (median 12 years), 12 patients are in New York Heart Association class I and one patient is in class II. Nine patients were in sinus rhythm and four were in atrial fibrillation. Although our experience indicates that good functional results can still be achieved many years after the onset of traumatic tricuspid valve insufficiency, earlier diagnosis and surgical treatment should increase the feasibility of tricuspid valve insufficiency, earlier diagnosis and surgical treatment should increase the feasibility of tricuspid valve repair, prevent progressive deterioration of right ventricular function, and increase the possibility of maintaining late sinus rhythm in a greater number of patients.

2012-01-01

Full Text Available Abstract Background Mitral valve thickness is used as a criterion to distinguish the classical from the non-classical form of mitral valve prolapse (MVP. Classical form of MVP has been associated with higher risk of mitral regurgitation (MR and concomitant complications. We sought to determine the relation of mitral valve morphology and motion to mitral regurgitation severity in patients with MVP. Methods We prospectively analyzed transthoracic echocardiograms of 38 consecutive patients with MVP and various degrees of MR. In the parasternal long-axis view, leaflets length, diastolic leaflet thickness, prolapsing depth, billowing area and non-coaptation distance between both leaflets were measured. Results Twenty patients (53% and 18 patients (47% were identified as having moderate to severe and mild MR respectively (ERO = 45 ± 27 mm2 vs. 5 ± 7 mm2, p Conclusions In patients with MVP, thick mitral leaflet is not associated with significant MR. Leaflet thickness is probably not as important in risk stratification as previously reported in patients with MVP. Other anatomical and geometrical features of the mitral valve apparatus area appear to be much more closely related to MR severity.

Communicating risks and benefits of medical exposures to patients

International Nuclear Information System (INIS)

Wall, B.F.

2001-01-01

An information leaflet for concerned patients is in preparation, which attempts to explain the risks and benefits of diagnostic medical exposures in terms suitable for the layman. In view of the wide variability in patient doses for the same examination and the considerable uncertainties in radiation risk coefficients, x-ray examinations have been divided into just four broad categories each spanning a factor of 10 in risk. The doses are put into perspective by comparison with those from natural background radiation. Sufficient quantitative information on the approximate level of the risks for some common diagnostic procedures is provided to allow patients to make an informed decision on whether the benefits, as described by the referring clinician, outweigh the radiation risks.

2017-11-01

Full Text Available Mitral valve plasty (MVP is preferred over mitral valve replacement (MVR for mitral regurgitation in humans because of its favorable effect on quality of life. In small dogs, it is difficult to repair multiple lesions in both leaflets using MVP. Herein, we report a case of severe mitral regurgitation caused by multiple severe lesions in the posterior leaflet (PL in a mixed Chihuahua. Initially, we had planned MVR with an artificial valve. However, MVP combined with artificial chordal reconstruction of both leaflets, semicircular suture annuloplasty, and valvuloplasty using a newly devised direct scallop suture for the PL was attempted in this dog. The dog recovered well and showed no adverse cardiac signs, surviving two major operations. The dog died 4 years and 10 months after the MVP due to non-cardiovascular disease. Our additional technique of using a direct scallop suture seemed useful for PL repair involving multiple scallops in a small dog.

one of the key targets in treating mitral regurgitation (MR) is reducing the otherwise progressive left ventricular (LV) remodeling that exacerbates MR and conveys adverse prognosis. We have previously demonstrated that severing 2 second-order chordae to the anterior mitral leaflet relieves tethering and ischemic MR acutely. The purpose of this study was to test whether this technique reduces the progression of LV remodeling in the chronic ischemic MR setting. a posterolateral MI was created in 18 sheep by obtuse marginal branch ligation. After chronic remodeling and MR development at 3 months, 6 sheep were randomized to sham surgery (control group) and 12 to second-order chordal cutting (6 each to anterior leaflet [AntL] and bileaflet [BiL] chordal cutting, techniques that are in clinical application). At baseline, chronic infarction (3 months), and follow-up at a mean of 6.6 months post-myocardial infarction (MI) (euthanasia), we measured LV end-diastolic (EDV) and end-systolic volume (ESV), ejection fraction, wall motion score index, and posterior leaflet (PL) restriction angle relative to the annulus by 2D and 3D echocardiography. All measurements were comparable among groups at baseline and chronic MI. At euthanasia, AntL and BiL chordal cutting limited the progressive remodeling seen in controls. LVESV increased relative to chronic MI by 109±8.7% in controls versus 30.5±6.1% with chordal cutting (Pbenefits have the potential to improve clinical outcomes.

Full Text Available Xenogenic leaflet material, bovine and porcine pericardium, is widely used for the fabrication of surgically implanted and transcatheter heart valve prostheses. As a biological material, long term durability of pericardium is limited due to calcification, degeneration and homogeneity. Therefore, polymeric materials represent a promising approach for a next generation of artificial heart valve leaflets with improved durability. Within the current study we analyzed the mechanical performance of polymeric structures based on elastomeric materials. Polymeric cast films were prepared and nonwovens were manufactured in an electrospinning process. Analysis of cyclic stress-strain behavior was performed, using a universal testing machine. The uniaxial cyclic tensile experiments of the elastomeric samples yielded a non-linear elastic response due to viscoelastic behavior with hysteresis. Equilibrium of stress-strain curves was found after a specific number of cycles, for cast films and nonwovens, respectively. In conclusion, preconditioning was found obligatory for the evaluation of the mechanical performance of polymeric materials for the use as artificial leaflet material for heart valve prostheses.

Interleaflet Coupling, Pinning, and Leaflet Asymmetry—Major Players in Plasma Membrane Nanodomain Formation

Science.gov (United States)

Fujimoto, Toyoshi; Parmryd, Ingela

2017-01-01

The plasma membrane has a highly asymmetric distribution of lipids and contains dynamic nanodomains many of which are liquid entities surrounded by a second, slightly different, liquid environment. Contributing to the dynamics is a continuous repartitioning of components between the two types of liquids and transient links between lipids and proteins, both to extracellular matrix and cytoplasmic components, that temporarily pin membrane constituents. This make plasma membrane nanodomains exceptionally challenging to study and much of what is known about membrane domains has been deduced from studies on model membranes at equilibrium. However, living cells are by definition not at equilibrium and lipids are distributed asymmetrically with inositol phospholipids, phosphatidylethanolamines and phosphatidylserines confined mostly to the inner leaflet and glyco- and sphingolipids to the outer leaflet. Moreover, each phospholipid group encompasses a wealth of species with different acyl chain combinations whose lateral distribution is heterogeneous. It is becoming increasingly clear that asymmetry and pinning play important roles in plasma membrane nanodomain formation and coupling between the two lipid monolayers. How asymmetry, pinning, and interdigitation contribute to the plasma membrane organization is only beginning to be unraveled and here we discuss their roles and interdependence. PMID:28119914

Influence of Printed Leaflets on Consumer Purchase Behavior

Full Text Available This article deals with the way customers perceive individual non-direct response printed leaflets and it is simultaneously focused on the question whether this material has any importance in general for customers during their purchase realization. The research is further concerned with the issue of the differences between customers living in family built-up areas and those who are living in residential housing. The research explores the differences related to preferences of various target groups. It identifies whether customers wish to receive printed advertising material into their letter boxes, what sort of media they read and what kinds of assortment are most frequently requested to appear in this form of promotion by customers. Preferences are aggregated by means of data classification based on different criteria and they provide a clue for better orientation in customer thinking.

Full Text Available Background: Patient information may assist in promoting shared decision-making, however it is imperative that the information presented is comprehensible and acceptable to the target audience. Objective: This study sought to explore the acceptability and comprehensibility of the ‘Medicines in Scotland: What’s the right treatment for you?’ factsheet to the general public. Methods: Qualitative semi-structured telephone interviews were conducted with members of the public. An interview schedule was developed to explore the acceptability and comprehensibility of the factsheet. Participants were recruited by a researcher who distributed information packs to attendees (n=70 of four community pharmacies. Interviews, (12-24 minutes duration, were audio recorded, transcribed verbatim and analysed using a framework approach. Results: Nineteen participants returned a consent form (27.1%, twelve were interviewed. Six themes were identified: formatting of the factsheet and interpretation; prior health knowledge and the factsheet; information contained in the factsheet; impact of the factsheet on behaviour; uses for the factsheet; and revisions to the factsheet. Conclusions: The factsheet was generally perceived as helpful and comprehensive. It was highlighted that reading the leaflet may generate new knowledge and may have a positive impact on behaviour.

Full Text Available BACKGROUND: Differentiating ischemic from non-ischemic functional mitral regurgitation‎ (FMR in patients with cardiomyopathy is important in terms of the therapeutic decision-making and prognosis, but might be clinically challenging. In this study, the deformation of mitral valve (MV indices in the prediction of the etiology of FMR was assessed using 2D transthoracic and tissue Doppler echocardiography.METHODS: This case-control study was conducted from April 2015 to January 2016 in Imam Reza Hospital in Mashhad, Iran. The participants consisted of 40 patients with ischemic cardiomyopathy (ICM and 22 with non-ischemic dilated cardiomyopathy (DCM who referred to the heart failure clinic. Transthoracic echocardiography was performed using the conventional 2D and tissue Doppler imaging (TDI. MV tenting area (TA, coaptation distance (CD, anterior and posterior mitral leaflet angles (AMLA and PMLA, and regional systolic myocardial velocity (Sm were measured.RESULTS: There were no significant differences in echocardiographic indices between the two groups, besides Sm and PMLA which were significantly lower and higher, respectively, in ICM subjects in comparison with DCM patients (P = 0.002. PMLA ≥ 40 degrees and Sm ≤ 4 cm/second have a relatively high value for discriminating the ischemic from non-ischemic origin of functional MR in subjects with systolic heart failure (sensitivity: 80.0% and 70.0%, specificity: 73.0% and 77.3%; P = 0.001 and P < 0.001; respectively. Multivariable logistic regression identified PMLA and anterior Sm as major determinants for ischemic MR {Odds ratio (OR [95% confidence interval (CI] = 0.89 (0.82-0.96, P = 0.003, OR (95% CI = 0.29 (0.14-0.60, P = 0.001, respectively}.CONCLUSION: The present study showed that PMLA and Sm had an independent significant association with the mechanism of FMR. These findings are suggestive of the predictive role of mitral deformation echocardiographic indices in the determination of the

This study assesses the results of the 'clover technique' (suturing together the middle point of the free edges of the tricuspid leaflets) for the treatment of tricuspid regurgitation (TR) due to severe prolapse or tethering. From 2001, 66 patients with severe TR due to prolapsing or tethered leaflets underwent 'clover repair'. Annuloplasty was associated in 64 patients (97%). The aetiology of TR was degenerative in 52 cases (79%), post-traumatic in eight (12%) and secondary to dilated cardiomyopathy (DCM) in six (9%). The main mechanism of TR was prolapse/flail of one leaflet in 15 patients (23%), of two leaflets in 31 (47%) and of all three leaflets in 14 (21%). The remaining six patients (9%) presented with severe leaflets' tethering. Four deaths (6%) occurred during hospitalisation and one patient died 3.6 years after surgery. Survival was 91 + or - 4.1% at 5 years. Follow-up of the 62 hospital survivors was 100% complete (mean length 3.5 + or - 1.6 years, range 13 months-7.1 years). At the last echocardiogram, no or mild TR was detected in 55 (88.7%) patients, moderate (2+/4+) in six (9.6%) and severe (4+/4+) in one patient (1.6%). Mean tricuspid valve area and gradient were 4.3 + or - 0.6 cm(2) and 2.8 + or -1.4 mmHg. In six patients, stress echocardiography was performed and no signs of tricuspid stenosis were detected. At the multivariable analysis, the degree of TR at hospital discharge was identified as the only predictor of TR > or = 2+ at follow-up. Midterm clinical and echocardiographic results confirm the role of the 'clover technique' in the surgical treatment of TR due to lesions, which are unlikely to be effectively treatable by annuloplasty alone.

Written Medicine Information (WMI) is one of the sources that patients use to obtain information concerning medicine. This paper aims to assess the readability of two types of WMIs in Arabic language based on vocabulary use and sentence structure using a panel of experts and consumers. This is a descriptive study. Two different types of materials, including the online text from King Abdullah Bin Abdulaziz Arabic Health Encyclopaedia (KAAHE) and medication leaflets submitted by the manufacturers to the Saudi Food and Drug Authority (SFDA) were evaluated. We selected a group of sentences from each WMI. The readability was assessed by experts (n = 5) and consumers (n = 5). The sentence readability of each measured using a specific criteria and rated as 1 = easy, 2 = intermediate, or 3 = difficult. A total of 4476 sentences (SFDA 2231; KAHEE 2245) extracted from websites or patient information leaflets on 50 medications and evaluated. The majority of the vocabulary and sentence structure was considered easy by both expert (SFDA: 68%; KAAHE: 76%) and consumer (SFDA: 76%; KAAHE: 84%) groups. The sentences with difficult or intermediate vocabulary and sentence structure are derived primarily from the precautions and side effects sections. The SFDA and KAAHE WMIs are easy to read and understand as judged by our study sample. However; there is room for improvement, especially in sections related to the side effects and precautions.

2011 drug packaging review: too many dangers and too many patients overlooked.

Science.gov (United States)

2012-05-01

Every year, Prescrire's analysis of drug packaging confirms the importance of taking packaging into account in assessing a drug's harm-benefit balance. Safe, tried and true options are available, yet the quality of most of the drug packaging Prescrire examined in 2011 left much to be desired. Few of the packaging items examined help prevent medication errors and many actually increase the risks: misleading and confusing labelling, dosing devices that create a risk of overdose, bottles without a child-proof cap, and inadequate or dangerous patient information leaflets. Umbrella brands continue to expand and are a potential source of medication errors. Some patients are at greater risk: the patient leaflets for NSAIDs endanger pregnant women and their unborn babies; children are insufficiently protected by paediatric packaging and are at risk due to the lack of child-proof caps on too many bottles. The raft of regulatory measures taken by the French drug regulatory agency (Afssaps) in the aftermath of the Mediator disaster overlooked the importance of packaging. Until drug regulatory agencies tackle the vast issue of drug packaging, it is up to healthcare professionals to protect patients from harm.

Schoch, Rafael L.; Barel, Itay; Brown, Frank L. H.; Haran, Gilad

2018-03-01

Supported lipid bilayers (SLBs) have been studied extensively as simple but powerful models for cellular membranes. Yet, potential differences in the dynamics of the two leaflets of a SLB remain poorly understood. Here, using single particle tracking, we obtain a detailed picture of bilayer dynamics. We observe two clearly separate diffusing populations, fast and slow, that we associate with motion in the distal and proximal leaflets of the SLB, respectively, based on fluorescence quenching experiments. We estimate diffusion coefficients using standard techniques as well as a new method based on the blur of images due to motion. Fitting the observed diffusion coefficients to a two-leaflet membrane hydrodynamic model allows for the simultaneous determination of the intermonolayer friction coefficient and the substrate-membrane friction coefficient, without any prior assumptions on the strengths of the relevant interactions. Remarkably, our calculations suggest that the viscosity of the interfacial water confined between the membrane and the substrate is elevated by ˜104 as compared to bulk water. Using hidden Markov model analysis, we then obtain insight into the transbilayer movement of lipids. We find that lipid flip-flop dynamics are very fast, with half times in the range of seconds. Importantly, we find little evidence for membrane defect mediated lipid flip-flop for SLBs at temperatures well above the solid-to-liquid transition, though defects seem to be involved when the SLBs are cooled down. Our work thus shows that the combination of single particle tracking and advanced hydrodynamic modeling provides a powerful means to obtain insight into membrane dynamics.

Research described here was carried out to explore possibilities of creating a web-based patient information system within the areas of thoracic surgery. Data were collected to distinguish and assess the actual information needs of patients (1) prior to surgical treatment, (2) before discharge, and (3) 8 months after the hospitalization using a follow-up questionnaire. Interviews were performed with patients undergoing heart surgery. The study included material of 19 consecutive patients undergoing coronary artery bypass surgery (12) and valve replacement (7), age 35-74, 13 males and 6 females with nonacademic background. Patient satisfaction with given information was high. Analysis of the interviews held at the hospital resulted in seven different categories describing and giving a picture of the patients' information needs and apprehension of received care. The results found in this study can be used as guidance for developers in their design and development process of a health information system.

Patients with AF who applied to the Cardiology Center in 2013-2014 (n=111 were included into the study. The oral anticoagulants (OAC were recommended to patients at the reference visit (n=97. Inquiry in questionnaire format was performed to assess the compliance to recommended therapy at the follow-up visit. Patients were divided into two groups according to taking/not-taking NOAC. Analysis of the facts that influence the compliance to NOAC therapy was performed.Results. At the reference visit 70 patients desired to receive NOAC. At the follow-up visit 29 (41.4% patients refused to take NOAC. Leading causes of NOAC refusal were satisfactory with warfarin (32.6%, the high price of these drugs (23.9%, the description of adverse reactions in the patient information leaflet for medicines (15.2%, and withdrawal by physician in outpatient clinic/hospital (8.7%. Preferential provision of medicines and warfarin therapy at the time of reference visit had a negative impact on the taking of NOAC. Patients taking NOAC were more aware of the possible outcomes of their illness, the possible side effects of OAC and were more familiar with patient information leaflet for medicines.Conclusion. The study assessed NOAC taking rate and the factors influencing patients' compliance to NOAC therapy.

[Ethical aspects of disclosing information on prenatal screening for Down's syndrome].

Tóth, Adél; Szabó, János

Giving detailed information on prenatal screening for Down's syndrome is considered as paramount since this medical procedure intends to enhance the patient's self-governance in reproductive issues. Not only the respect for autonomy, but also the increased maternal anxiety and the reproductive decisions following the positive test result demand from the genetic professional to offer the test through genetic counselling. The counsellor's awareness about the expectations of pregnant women and the clarification of her own attitude concerning the screening can contribute to the effectiveness of counselling. The content of information embraces the technical aspects of screening and its consequences, like the description of Down's syndrome, the method of screening, the way of risk assessment, the detection rate, the false positive and false negative test results, the diagnostic procedures, and the termination of pregnancy. Written information leaflets should be completed by personal communication as the combination of these two forms has proved to be the most useful. The process of consultation is influenced by the communication skill of the genetic professional and the information seeking activity of the patient, so doctors should be trained to communicate better and patients should be encouraged to get more information about the screening.

Acetaminophen (paracetamol), the highest over-the-counter (OTC) selling drug in France, is also the first cause of acute hepatic failure. We aimed to assess the good use and the knowledge of acetaminophen in a setting of urban self-medicated patients. We conducted a prospective observational study in randomly selected community pharmacies of Metz (France) agglomeration. Patients coming to buy OTC acetaminophen for themselves or their family had to answer to an anonymous autoquestionnaire. Responses were individually and concomitantly analyzed through 3 scores: good use, knowledge and overdosage. Twenty-four community pharmacies participated and 302 patients were interviewed by mean of a dedicated questionnaire. Most of patients (84.4%) could be considered as "good users" and independent factors of good use were (i) a good knowledge of acetaminophen (OR=5.3; P<0.0001) and more surprisingly; (ii) the fact of having no children (parentality: OR=0.1; P=0.006). Responses corresponding to involuntary overdosage were mostly due to a too short interval between drug intakes (3hours). Only 30.8% of patients were aware of liver toxicity of acetaminophen and only 40.7% knew the risk of the association with alcohol. Both good use and knowledge were significantly higher in patients looking for information from their pharmacist, physician and package leaflet. Patients should definitely be better informed about acetaminophen to warrant a better safety of its consumption. Pharmacists and physicians have to remind patients the risk factors of unintentional overdose and liver toxicity. Package leaflets have also to be more informative.

2012-03-29

Better use of e-health services by patients could improve outcomes and reduce costs but there are concerns about inequalities of access. Previous research in outpatients suggested that anonymous personal email support may help patients with long term conditions to use e-health, but recruiting earlier in their 'journey' may benefit patients more. This pilot study explored the feasibility and cost of recruiting patients for an e-health intervention in one primary care trust. The sample comprised 46 practices with total patient population of 250,000. We approached all practices using various methods, seeking collaboration to recruit patients via methods agreed with each practice. A detailed research diary was kept of time spent recruiting practices and patients. Researcher time was used to estimate costs. Patients who consented to participate were offered email support for their use of the Internet for health. Eighteen practices agreed to take part; we recruited 27 patients, most (23/27) from five practices. Practices agreed to recruit patients for an e-health intervention via waiting room leaflets (16), posters (16), practice nurses (15), doctors giving patients leaflets (5), a study website link (7), inclusion in planned mailshots (2), and a special mailshot to patients selected from practice computers (1). After low recruitment response we also recruited directly in five practices through research assistants giving leaflets to patients in waiting rooms. Ten practices recruited no patients. Those practices that were more difficult to recruit were less likely to recruit patients. Leaving leaflets for practice staff to distribute and placing posters in the practice were not effective in recruiting patients. Leaflets handed out by practice nurses and website links were more successful. The practice with lowest costs per patient recruited (£70) used a special mailshot to selected patients. Recruitment via general practice was not successful and was therefore expensive

Transbilayer lipid asymmetry is a fundamental characteristic of the eukaryotic cell plasma membrane (PM). While PM phospholipid asymmetry is well documented, the transbilayer distribution of PM sterols such as mammalian cholesterol and yeast ergosterol is not reliably known. We now report that sterols are asymmetrically distributed across the yeast PM, with the majority (~80%) located in the cytoplasmic leaflet. By exploiting the sterol-auxotrophic hem1Δ yeast strain we obtained cells in which endogenous ergosterol was quantitatively replaced with dehydroergosterol (DHE), a closely related fluorescent sterol that functionally and accurately substitutes for ergosterol in vivo. Using fluorescence spectrophotometry and microscopy we found that membrane-impermeant collisional quenchers (spin-labeled phosphatidylcholine and trinitrobenzene sulfonic acid). Efficient quenching was seen only after the cells were disrupted by glass-bead lysis or repeated freeze-thaw to allow quenchers access to the cell interior. The extent of quenching was unaffected by treatments that deplete cellular ATP levels, collapse the PM electrochemical gradient or affect the actin cytoskeleton. However, alterations in PM phospholipid asymmetry in cells lacking phospholipid flippases resulted in a more symmetric transbilayer distribution of sterol. Similarly, an increase in the quenchable pool of DHE was observed when PM sphingolipid levels were reduced by treating cells with myriocin. We deduce that sterols comprise up to ~45% of all inner leaflet lipids in the PM, a result that necessitates revision of current models of the architecture of the PM lipid bilayer. © 2017 John Wiley & Sons A/S.

Background Complementary and Alternative Medicine (CAM) is increasingly popular with cancer patients and yet information provision or discussion about CAM by health professionals remains low. Previous research suggests that patients may fear clinicians' 'disapproval' if they raise the subject of CAM, and turn to other sources to acquire information about CAM. However, little empirical research has been conducted into how cancer patients acquire, and, more importantly evaluate CAM information before deciding which CAM therapies to try. Methods Qualitative study, comprising semi-structured interviews with 43 male cancer patients of varying ages, cancer type and stage of illness, 34 of whom had used CAM. They were recruited from a range of NHS and non-NHS settings in Bristol, England. Results As a result of the lack of CAM information from health professionals, men in this study became either 'pro-active seekers' or 'passive recipients' of such information. Their main information resource was the 'lay referral' network of family, friends and acquaintances, especially females. 'Traditional' information sources, including books, magazines, leaflets and the media were popular, more so in fact than the internet. Views on the internet ranged from enthusiasm or healthy scepticism through to caution or disinterest. CAM information was generally regarded as 'empowering' as it broadened treatment and self-care options. A minority of participants were information averse fearing additional choices that might disrupt their fragile ability to cope. There was general consensus that CAM information should be available via the NHS, to give it a 'stamp of approval', which combined with guidance from informed health professionals, could help patients to make 'guided' choices. However, a small minority of these men valued the independence of CAM from the NHS and deliberately sought 'alternative' information sources and treatment options. Men were selective in identifying particular

Patient anxiety in magnetic resonance imaging centres: Is further intervention needed?

International Nuclear Information System (INIS)

Tischler, Victoria; Calton, Tim; Williams, Michael; Cheetham, Anna

2008-01-01

Background: Anxiety is commonly reported by patients attending for Magnetic Resonance Imaging (MRI) scanning. This cross sectional postal survey sought the views of radiographers regarding: levels of patient anxiety, methods used to manage this before and during scanning, and the need for additional interventions to reduce anxiety. Results: Participants reported that they used procedures such as information leaflets, pre-scan visits and music to inform patients about the scan procedure and to reduce anxiety. Despite this, high levels of patient anxiety were reported, leading to scan disruption in some centres. The causes of anxiety concurred with previous research findings, for example, the scan environment, noise levels and fear of what the scan may reveal. Most participants were opposed to the idea of a multi-media intervention to reduce anxiety but this was often related to resource restrictions. Conclusions: Despite most centres using anxiety reducing techniques, many still report scan disruption suggesting there is a need to improve support for patients

PURPOSE: Patient-specific heart and valve models have shown promise as training and planning tools for heart surgery, but physically realistic valve models remain elusive. Available proprietary, simulation-focused heart valve models are generic adult mitral valves and do not allow for patient-specific modeling as may be needed for rare diseases such as congenitally abnormal valves. We propose creating silicone valve models from a 3D-printed plastic mold as a solution that can be adapted to any individual patient and heart valve at a fraction of the cost of direct 3D-printing using soft materials. METHODS: Leaflets of a pediatric mitral valve, a tricuspid valve in a patient with hypoplastic left heart syndrome, and a complete atrioventricular canal valve were segmented from ultrasound images. A custom software was developed to automatically generate molds for each valve based on the segmentation. These molds were 3D-printed and used to make silicone valve models. The models were designed with cylindrical rims of different sizes surrounding the leaflets, to show the outline of the valve and add rigidity. Pediatric cardiac surgeons practiced suturing on the models and evaluated them for use as surgical planning and training tools. RESULTS: Five out of six surgeons reported that the valve models would be very useful as training tools for cardiac surgery. In this first iteration of valve models, leaflets were felt to be unrealistically thick or stiff compared to real pediatric leaflets. A thin tube rim was preferred for valve flexibility. CONCLUSION: The valve models were well received and considered to be valuable and accessible tools for heart valve surgery training. Further improvements will be made based on surgeons' feedback.

In the current climate of increasing awareness, patients are demanding more knowledge about forthcoming operations. The patient information accounts for a considerable part of the physician's daily clinical routine. Unfortunately, only a small percentage of the information is understood by the patient after solely verbal elucidation. To optimise information delivery, different auxiliary materials are used. In a prospective study, 52 consecutive stationary patients, scheduled for an elective lumbar disc operation were asked to use a web-based audiovisual patient information system. A combination of pictures, text, tone and video about the planned surgical intervention is installed on a tablet personal computer presented the day before surgery. All patients were asked to complete a questionnaire. Eighty-four percent of all participants found that the audiovisual patient information system lead to a better understanding of the forthcoming operation. Eighty-two percent found that the information system was a very helpful preparation before the pre-surgical interview with the surgeon. Ninety percent of all participants considered it meaningful to provide this kind of preoperative education also to patients planned to undergo other surgical interventions. Eighty-four percent were altogether "very content" with the audiovisual patient information system and 86% would recommend the system to others. This new approach of patient information had a positive impact on patient education as is evident from high satisfaction scores. Because patient satisfaction with the informed consent process and understanding of the presented information improved substantially, the audiovisual patient information system clearly benefits both surgeons and patients.

Full Text Available Abstract Background There is broad agreement that cancer screening invitees should know the risks and benefits of testing before deciding whether to participate. In organised screening programmes, a primary method of relaying this information is via leaflets provided at the time of invitation. Little is known about why individuals do not engage with this information. This study assessed factors associated with reading information leaflets provided by the three cancer screening programmes in England. Methods A cross-sectional survey asked screening-eligible members of the general population in England about the following predictor variables: uptake of previous screening invitations, demographic characteristics, and ‘decision-making styles’ (i.e. the extent to which participants tended to make decisions in a way that was avoidant, rational, intuitive, spontaneous, or dependent. The primary outcome measures were the amount of the leaflet that participants reported having read at their most recent invitation, for any of the three programmes for which they were eligible. Associations between these outcomes and predictor variables were assessed using binary or ordinal logistic regression. Results After exclusions, data from 275, 309, and 556 participants were analysed in relation to the breast, cervical, and bowel screening programmes, respectively. Notable relationships included associations between regularity of screening uptake and reading (more of the information leaflets for all programmes (e.g. odds ratio: 0.16 for participants who never/very rarely attended breast screening vs. those who always attended previously; p = .009.

A 33-year-old, previously healthy male presented with respiratory distress and underwent intubation. A physical examination revealed a holosystolic murmur and pupillary abnormalities. Echocardiography revealed a flail anterior mitral valve leaflet with ruptured chordae and severe mitral regurgitation. The patient underwent urgent mitral valve replacement and tolerated the procedure well. The mitral valve leaflet was myxomatous and calcified -- an unusual find in such a patient. An ophthalmology consultation was obtained and the patient diagnosed with Axenfeld-Rieger syndrome, a disorder of the anterior ocular chamber that has been associated with cardiac malformations. The present case report adds to the body of literature which suggests a correlation between Axenfeld-Rieger syndrome and valvular abnormalities. Hence, it is believed prudent that patients with Axenfeld-Rieger syndrome should undergo echocardiographic screenings for valvular abnormalities.

Aim of this study is the evaluation of the impact of preoperative informative session using a Multimedia Health Educational Program (MHEP) on patients undergoing elective Laparoscopic Cholecystectomy (LC) for cholelithiasis, preoperative anxiety and postoperative pain and nausea. Sixty consecutive patients scheduled for elective LC were considered for enrollment in the trial. Patients were assigned randomly to four groups: Group A included 15 patients, preoperatively informed regarding LC through the MHEP presented by a Registered Nurse (RN). Group B included 15 patients preoperatively informed through a leaflet (designed and developed using the exact contents of the MHEP). In Group C, there were 15 patients who were being informed verbally from the RN. Finally, the control Group D included 15 patients, who had the conventional preoperative information about the operation and postoperative course by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, C. Preoperative assessment of patient's knowledge about cholelithiasis and LC was performed after informative session, and was based on a specifically developed "closed, true-false" questionnaire. Preliminary results suggest that conventional information provided by the attending surgeon (Group D) is inadequate. Specifically developed informative sessions with the contribution of MHEP seems to be effective on reducing preoperative anxiety and postoperative pain, in patients undergoing elective LC.

Because mitral valve dysfunction in adults with Marfan syndrome is poorly characterized, this study compares mitral valve pathophysiology and morphology with that of myxomatous mitral disease, documents types of mitral valve operations, and assesses long-term survival and durability of mitral valve surgery in Marfan patients. From May 1975 to June 2000, 27 adults with Marfan syndrome underwent mitral valve surgery. Their valve pathophysiology and morphology was compared with that of 119 patients with myxomatous mitral disease undergoing surgery from September 1995 to March 1999. Survival and repair durability were assessed at follow-up. Compared with myxomatous disease patients, Marfan patients had less posterior leaflet prolapse (44% versus 70%, p = 0.01), more bileaflet (44% versus 28%, p = 0.09) and anterior leaflet prolapse (11% versus 3%, p = 0.07), and presented earlier for surgery (age 41 +/- 12 years versus 57 +/- 13, p Marfan patients had longer and thinner leaflets. Mitral valve repair was performed less frequently in Marfan (16 of 27, 59%) than myxomatous disease patients (112 of 119, 94%). There were no hospital deaths; at 10 years, survival was 80% and freedom from reoperation 96%, with only 1 reoperation among the 16 repairs. Mitral valve pathophysiology and morphology differ between Marfan and myxomatous mitral valve diseases. Valve repair in Marfan patients is durable and gives acceptable long-term results, even in adults who present with advanced mitral valve pathology. With increasing use of the modified David reimplantation operation and sparing of the aortic valve, mitral valve repair is a greater imperative, particularly since we have not had to reoperate on any Marfan patients with reimplantations.

Background: As a result of increased interest and public demand, providing patients with adequate information about radiooncology has become more and more difficult for the doctor. Insufficient patient information can not only cause anxiety for the patient, but can also lead to legal action against the physician. In order to gain a deeper insight into our clinical practice of providing patient information, we developed a special questionnaire. We describe our first experiences in using this questionnaire at our institute. Patients and methods: We examine the amount of information and level of satisfaction, as well as the agreement of assessment between patient and physician after the provision of standard patient information before and at the end of radiotherapy. 51 consecutive patients were interviewed with a newly designed questionnaire. The first questioning with 13 items was carried out before radiotherapy and the second with ten items was done at the end of treatment. Sum scores for information and satisfaction were defined and agreement was measured by the weighted κ coefficient. Results: Global level of information and satisfaction was good, and a significant increase in information level and a significant decline in satisfaction were seen between questionnaire 1 and 2. Agreement between patient and physician was fair, for example intent of treatment resulted in a κ coefficient of 0.34, and poor for the doctor's role with a κ coefficient of -0.002. Only 52% of the patients who received palliative radiotherapy rated correctly the non-curative intent of treatment, whereas 86% of the patients who received curative radiotherapy made a correct statement. Before radiotherapy, emotional state was often both negatively and positively assessed by the patients. Conclusion: Our short questionnaire is simple and easy to understand. It provides insights into patient information with respect to assessment of the information, satisfaction level, and agreement between

The Impact of Fluid Inertia on In Vivo Estimation of Mitral Valve Leaflet Constitutive Properties and Mechanics.

Bark, David L; Dasi, Lakshmi P

We examine the influence of the added mass effect (fluid inertia) on mitral valve leaflet stress during isovolumetric phases. To study this effect, oscillating flow is applied to a flexible membrane at various frequencies to control inertia. Resulting membrane strain is calculated through a three-dimensional reconstruction of markers from stereo images. To investigate the effect in vivo, the analysis is repeated on a published dataset for an ovine mitral valve (Journal of Biomechanics 42(16): 2697-2701). The membrane experiment demonstrates that the relationship between pressure and strain must be corrected with a fluid inertia term if the ratio of inertia to pressure differential approaches 1. In the mitral valve, this ratio reaches 0.7 during isovolumetric contraction for an acceleration of 6 m/s(2). Acceleration is reduced by 72% during isovolumetric relaxation. Fluid acceleration also varies along the leaflet during isovolumetric phases, resulting in spatial variations in stress. These results demonstrate that fluid inertia may be the source of the temporally and spatially varying stiffness measurements previously seen through inverse finite element analysis of in vivo data during isovolumetric phases. This study demonstrates that there is a need to account for added mass effects when analyzing in vivo constitutive relationships of heart valves.

This study aims to compare mid-long-term clinical outcomes between patients younger than 60 years of age undergoing bioprosthetic and mechanical aortic valve replacement. From January 2002 to December 2009, patients younger than 60 years of age who received Medtronic Hancock II porcine bioprostheses were selected and compared with those who received mechanical bi-leaflet valves in the aortic position. A stepwise logistic regression propensity score identified a subset of 112 evenly matched patient-pairs. Mid-long-term outcomes of survival, valve-related reoperations, thromboembolic events and bleeding events were assessed. The follow-up was only 95.1% complete. Fourteen measurable variables were statistically similar for the matched cohort. Postoperative in-hospital mortality was 3.6% (bioprosthetic valves) and 2.7% (mechanical valves) (P = 0.700). Survival at 5 and 10 years was 96.3 and 88.7% for patients receiving bioprosthetic valve replacement versus 96.3 and 87.9% for patients receiving mechanical valve replacement (P = 0.860), respectively. At 5 and 10 years after operations, freedom from valve-related reoperation was 97.2 and 94.8% for patients receiving mechanical valve replacement, and 96.3 and 90.2% for patients receiving bioprosthetic valve replacement (P = 0.296), respectively. There was no difference between freedom from thromboembolic events (P = 0.528) and bleeding events (P = 0.128) between the matched groups during the postoperative 10 years. In patients younger than 60 years of age undergoing aortic valve replacement, mid-long-term survival rate was similar for patients receiving bioprosthetic versus mechanical valve replacement. Bioprosthetic valves were associated with a trend for a lower risk of anticoagulation treatment and did not have significantly greater likelihood of a reoperation. These findings suggest that a bioprosthetic valve may be a reasonable choice for AVR in patients younger than 60 years of age. © The Author 2015. Published by

Full Text Available Abstract Background In the UK public concern about the safety of the combined measles, mumps and rubella [MMR] vaccine continues to impact on MMR coverage. Whilst the sharp decline in uptake has begun to level out, first and second dose uptake rates remain short of that required for population immunity. Furthermore, international research consistently shows that some parents lack confidence in making a decision about MMR vaccination for their children. Together, this work suggests that effective interventions are required to support parents to make informed decisions about MMR. This trial assessed the impact of a parent-centred, multi-component intervention (balanced information, group discussion, coaching exercise on informed parental decision-making for MMR. Methods This was a two arm, cluster randomised trial. One hundred and forty two UK parents of children eligible for MMR vaccination were recruited from six primary healthcare centres and six childcare organisations. The intervention arm received an MMR information leaflet and participated in the intervention (parent meeting. The control arm received the leaflet only. The primary outcome was decisional conflict. Secondary outcomes were actual and intended MMR choice, knowledge, attitude, concern and necessity beliefs about MMR and anxiety. Results Decisional conflict decreased for both arms to a level where an 'effective' MMR decision could be made one-week (effect estimate = -0.54, p Conclusions Whilst both the leaflet and the parent meeting reduced parents' decisional conflict, the parent meeting appeared to enable parents to act upon their decision leading to vaccination uptake.

In response to the evolution of the information-seeking behaviour of patients and concerns from health professionals regarding cancer patient information, the French National Federation of Comprehensive Cancer Centres (FNCLCC) introduced, in 1998, an information and education program dedicated to patients and relatives, the SOR SAVOIR PATIENT program. The methodology of this program adheres to established quality criteria regarding the elaboration of patient information. Cancer patient information developed in this program is based on clinical practice guidelines produced by the FNCLCC and the twenty French regional cancer centres, the National League against Cancer, The National Cancer Institute, the French Hospital Federation, the National Oncology Federation of Regional and University Hospitals, the French Oncology Federation of General Hospitals, many learned societies, as well as an active participation of patients, former patients and care-givers. The handbook SOR SAVOIR PATIENT Understanding nephro-blastomas is an adapted version of various scientific publications and international clinical practice guidelines, validated by oncology experts and by the Nephro-blastomas Committee of the French Society against Cancers and Leukemias in children and adolescents (SFCE). It was elaborated with the active participation of parents and other family members. It is meant to provide a basis for the explanation of the disease, to help parents asking questions, and to facilitate discussions with the health-care team. It is available from the FNCLCC (101, rue de Tolbiac, 75013 PARIS, Tel. (0033)1 76 64 78 00, www.fncicc.fr). This document was validated at the end of 2005 and published in May 2006. SOR SAVOIR PATIENT guides are systematically updated when new research becomes available. Information leaflets, extracted from the handbook SOR SAVOIR PATIENT Understanding nephro-blastomas and published in this edition of the Cancer et Radiotherapie, describe the physiopathology

Lyme disease or Lyme borreliosis (LB) is the most common tick-borne disease both in the United States and Europe. Children, in particular, are at high risk of contracting LB. Since child-specific educational tools on ticks, tick bites and LB are lacking, we developed an online educational video game. In this study, we compared the effectiveness of an online educational video game versus a newly developed leaflet aimed to improve prevention of tick bites and LB among Dutch schoolchildren. A total of 887 children, aged 9-13 years and attending the two final years of primary schooling, were recruited from 25 primary schools in June and July 2012. They were assigned through cluster randomization to one of three intervention groups: 'game' (22.4%), 'leaflet' (35.6%) or 'control' (41.9%). Prior to and directly following intervention, the children were asked to complete a short questionnaire. The main outcome measures were knowledge, perception (perceived susceptibility and importance) and preventive behavior in relation to tick bites and LB. Generalized linear mixed models were used to analyze the data. In the game group, the leaflet group and the control group, knowledge about ticks and tick bites improved significantly. The game was also an effective tool for improving preventive behavior; the frequency of checking for ticks increased significantly. However, there were no significant differences in knowledge improvement between the interventions. The game outperformed the leaflet in terms of improving preventive behavior, whereas the frequency of tick checks increased significantly. But this frequency didn't increase more than in the control group. The positive knowledge effects observed in the control group suggests the presence of a mere measurement effect related to completion of the questionnaire. The game did not outperform the leaflet or control group on all outcome measures. Therefore, the game may be of value as a complementary role, in addition to other media

BACKGROUND: Post-splenectomy infection has a mortality rate of up to 70%. Previously we have published data confirming the poor adherence to best practice guidelines with relation to management of the asplenic patient. A defined protocol of care was established, staff education commenced and a \\'patient information leaflet\\' made available. AIM: To ascertain whether management of the asplenic patient has improved since the implementation of a structured programme of care. METHOD: Retrospective chart review of all splenectomies performed in Beaumont Hospital between 2002 and 2008. RESULTS: Overall, 75.9% of patients were documented as having received the recommended vaccinations. Of these, 48.7% were not timed according to recommended guidelines. Prophylactic antibiotics were documented as prescribed in all but five patients discharged. CONCLUSIONS: These results demonstrate an improvement in post-splenectomy care between 2002 and 2008. However, further improvements are necessary.

In spite of extensive research, no effective treatment of primary burning mouth syndrome (BMS) still exists. The aim of this study was to determine the impact of informative intervention/reassurance on pain perception and quality of life in patients with primary BMS. Informative intervention/reassurance was undertaken in 28 patients diagnosed with primary BMS. Patients received information about all aspects of BMS verbally and in an informative leaflet. Numerical scale (0-10), Pain Catastrophizing Scale and Oral Health Impact Profile-14 (OHIP-14) were used to assess pain intensity, pain perception, and quality of life before the intervention and 6 months after. No other treatment was given to the patients. Significant reduction in symptom intensity, pain catastrophizing along with positive increase in the quality of life compared with baseline, was observed on a follow-up examination 6 months after the informative intervention (P < 0.001). The results of this study confirm that objective informing/reassurance of patients with primary BMS can result in decreased catastrophizing and improvement in the quality of life. By eliminating/changing negative patterns of behavior, a reduction in symptoms comparable with pharmacological treatment can be achieved. © 2016 John Wiley & Sons A/S.

To examine the effectiveness of newly developed materials for providing health-related information to the worksite population, we compared the amount of attention that employees paid to the materials. Study subjects were 2,361 employees in six companies participating in an intervention program between 2002 and 2003. Three kinds of media were used as tools for providing health information: [1] Point Of Purchase advertising menus (POP menus) were placed on all tables in company restaurants, [2] posters were put on walls and [3] leaflets were distributed at health-related events. One year or more after the introduction of these media, we compared the amount of attention paid to each type of medium. Amongst the three types of media, the POP menu drew the most attention, although results were not consistent in all gender and company groups. Every piece of information provided by the POP menus was "always" or "almost always" read by 41% of the men and 51% of the women surveyed. The corresponding rate for posters was 30% in men and 32% in women. For leaflets, only 16% of men and 22% of women read almost all of the leaflets. More attention was paid to the POP menu when the sample was women, older, and ate at the company restaurant at least three times a week. The POP menu may provide health-related information to a broader range of people than posters and leaflets, therefore, it is an effective material for population strategy.

The article represents results of a theoretical work in the field of nursing education, with the topic: Verbal Patient Information through Nurses--A Case of Stroke Patients. The literature review and analysis show that there is a shortage in (stroke) patient information generally and a lack of successful concepts and strategies for the verbal (stroke) patient information through nurses in hospitals. The authors have developed a theoretical basis for health information as a nursing intervention and this represents a model of health information as a "communicational teach-and-learn process", which is of general application to all patients. The health information takes place as a separate nursing intervention within a non-public, face-to-face communication situation and in the steps-model of the nursing process. Health information is seen as a learning process for patients and nurses too. We consider learning as information production (constructivism) and information processing (cognitivism). Both processes are influenced by different factors and the illness-situation of patients, personality information content and the environment. For a successful health information output, it is necessary to take care of these aspects and this can be realized through a constructivational understanding of didactics. There is a need for an evaluation study to prove our concept of health information.

Little is known about the level of information on implant dentistry in the public. A representative opinion poll on dental implants in the Austrian population was published in 2003 (Clinical Oral Implants Research 14:621-642). Seven years later, the poll was rerun to assess the up-to-date information level and evaluate recent progress and trends in patients' mindset on dental implants. One thousand adults--representative for the Austrian population--were presented with a total of 19 questionnaire items regarding the level and the sources of information about dental implants as well as the subjective and objective need for patient information. Compared with the survey of 2003, the subjective level of patient information about implant dentistry has significantly increased in the Austrian population. The patients' implant awareness rate was 79%. The objective level of general knowledge about dental implants was still all but satisfactory revealing unrealistic patient expectations. Three-quarters trusted their dentists for information about dental implants, while one-quarter turned to the media. The patients' wish for high-quality implant restorations was significantly higher than in 2003, yet the majority felt that only specialists should perform implant dentistry. This representative survey reveals that dentists are still the main source of patient information, but throws doubt on the quality of their public relations work. Dentists must improve communication strategies to provide their patients with comprehensible, legally tenable information on dental implants and bridge information gaps in the future. © 2010 John Wiley & Sons A/S.

Echocardiographic examination was performed in all subjects and the correlation between the echocardiographic features of the mitral valve and the hypermobility score were investigated. "nResults: The frequency of JHM in patients with MVP was found to be significantly higher than that of controls (26.3% vs. 7.8%, with mean JHM scores of 3.1+/-2.2 and 1.9+/-1.7, respectively. The patients in the MVP group had significantly increased the anterior mitral leaflet thickness (AMLT, 3.4+/-0.4 mm vs. 3.0+/-0.3 mm; p<0.0005 and maximal leaflet displacement (MLD, 2.4+/-0.3 mm vs. 1.5+/-0.2 mm; p<0.0005 compared to the controls. "nConclusions: We detect a statistically significant relationship between isolated MVP and joint hypermobility as well as between the severity of JHM and echocardiographic features of the mitral leaflets. These results suggest a common etiology for MVP and JHM, which should be investigated in future well-conducted studies.

Somogyi, O; Zelko, R

Although the non-conventional dosage forms (e.g. modified release per oral systems or transdermal patches) have more significant advantages than other conventional dosage forms, the pa- tients have to apply them correctly in their home medicine using to reach the effective and safe therapy. A guideline of relevant application instructions contribute to development of an effective pharmaceutical counseling in community pharmacies. The counseling and advices can improve the patients' knowledge concerning application rules of different new dosage forms (health- literacy) with patient adherence. Finally it will result more effective and safer therapies. The aim of our Hungarian questionnaire surveys was to explore the patients' drug application habits or application errors and improve special verbal counseling of mentioned non-conventional dosage forms in community pharmacies. Understandable patient information leaflets were developed about application rules and besides the levels of patients' reading comprehension was evaluated in case of the leaflet of medicinal patches. The results show that a properly developed text is useful for the majority of patients but they need the verbal explanation as well, moreover there is a demand for the verbal counseling in community pharmacies. The most common application errors were explored and the most effective instructions or application rules were collected for the pharmacists and patients concerning the modified release tablets or capsules and transdermal patches.

Aim of this study is the evaluation of the impact of a multimedia CD (MCD) on preoperative anxiety and postoperative recovery of patients undergoing elective laparoscopic cholecystectomy (LC). Sixty consecutive candidates for elective LC were randomly assigned to four groups. Group A included 15 patients preoperatively informed regarding LC through the MCD presented by Registered Nurse (RN). Patients in group B (n = 15) were informed through a leaflet. Patients in group C (n = 15) were informed verbally from a RN. Finally, the control Group D included 15 patients informed conventionally by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, and C. Preoperative assessment of knowledge about LC was performed after each informative session through a questionnaire. Evaluation of preoperative anxiety was conducted using APAIS scale. Postoperative pain and nausea scores were measured using an NRS scale, 16 hours after the patient had returned to the ward. Statistical processing of the results (single linear regression) showed that patients in groups A, B, and C achieved a higher knowledge score, less preoperative anxiety score and less postoperative pain and nausea, compared to Group D. In multiple regression analysis, group A had a higher knowledge score compared to the four groups (p Informative sessions using MCD is an effective means of improving patient's preoperative knowledge, especially in day-surgery cases, like LC.

Utilisation of information technology (IT) in the treatment of people with severe mental health problems is an unknown area in Europe. Use of IT and guiding patients to relevant sources of health information requires that nursing staff have positive attitudes toward computers and accept IT use as a part of daily practises. The aim of the study was to assess the effects of the implementation of a web-based patient support system on staff's attitudes towards computers and IT use on psychiatric wards. Hundred and forty-nine nurses in two psychiatric hospitals in Finland were randomised to two groups to deliver patient education for patients with schizophrenia and psychosis with a web-based system (n = 76) or leaflets (n = 73). After baseline nurses were followed-up for 18 months after the introduction of the system. The primary outcome was nurses' motivation to utilise computers, and the secondary outcomes were nurses' beliefs in and satisfaction with computers, and use of computer and internet. There were no statistically significant differences between study groups in attitudes towards computers (motivation p = 0.936, beliefs p = 0.270, satisfaction p = 0.462) and internet use (p = 0.276). However, nurses' general computer use (p = 0.029) increased more in the leaflet group than in the IT intervention group. We can conclude that IT has promise as an alternative method in patient education, as the implementation of the web-based patient support system in daily basis did not have a negative effect on nurses' attitudes towards IT. © 2010 The Authors.

Barlow disease is a still challenging pathology for the surgeon. Aim of the present study is to report anatomic abnormalities of mitral valve in patients undergoing mitral valve repair. Between January 1st, 2007, and December 31st, 2010, 85 consecutive patients (54 men and 31 women, mean age 59 +/- 14 years--range: 28-85 years) with the features of a Barlow mitral valve disease underwent mitral repair Forty seven percent of patients were in New York Heart Association functional class III or IV. Preoperative transesophageal echocardiography was compared with anatomical findings at the moment of surgery. Transthoracic echocardiography diagnosis of Barlow disease according to the criteria described by Carpentier was confirmed at anatomical inspection. Annular calcifications were found in 28 patients while 7 patients presented single or multiple clefts. A flail posterior mitral leaflet was detected in 32 subjects, while a flail anterior leaflet in 8. Elongation of chordae tendineae was demonstrated in 45 patients and chordal rupture in 31. All patients showed at trans esophageal echocardiography the typical features of Barlow disease. Seventy-seven (90.6%) patients had severe mitral valve regurgitation, in the remaining 9.4% it was moderate to severe. Transesophageal echocardiography failed to identify clefts in 2/7 and chordal rupture in 4/31. bileaflet prolapse > 2 mm, billowing valve with excess tissue and thickened leaflets > or = 3 mm, and severe annular dilatation, are characteristics of Barlow disease, however the identification of the associated and complex abnormalities of mitral valve is necessary to obtain optimal valve repair.

This virtual issue (VI) has been assembled to coincide with the 8th Annual Patient Information Conference 2013 organised by the UK Patient Information Forum (PiF). The conference theme 'Information and support - a service in its own right' is a response to policy documents and initiatives in both Scotland and England which signal the coming of age of patient/consumer information. The VI consists of a collection of open access articles and addresses the question 'What can health science librarians do to ensure that the public are able to find, appraise and use health information?' This material provides research evidence, and examples of the types of initiatives librarians have undertaken to make information a health and care service in its own right. Two recurrent messages are that health science librarians need to form partnerships with healthcare providers and they have a role to play in improving health literacy skills. © 2013 The authors.

Erectile dysfunction (ED) is the most common male sexual dysfunction and has a negative impact on masculinity and self-esteem. Phosphodiesterase type 5 inhibitors, including sildenafil, are the first-line treatment option for ED. Providing appropriate information regarding suitability for using sildenafil is important. The purpose of this study was to assess whether a broad spectrum of men could appropriately evaluate their suitability for 50-mg sildenafil after reviewing patient information materials. Patient information (Pack) on appropriate use of 50-mg sildenafil and patient information leaflet (PIL), a Web survey including demographics, self-assessed suitability for sildenafil use, and suitability screener. A randomly selected, population-representative Web-based panel of males in the UK was recruited for this study. Eligible men answered a brief sociodemographic questionnaire and then were presented with the Pack. If a participant desired additional information, he could also review the PIL. The participants then rated the Pack and PIL (if reviewed), self-assessed their suitability for sildenafil use, and completed a previously validated screener for suitability. A total of 1,275 men aged 40 and above were included in these analyses; the mean age was 57.8 ± 9.9 years. A total of 1,054 men reported ED; 517 men (40.5%) deemed themselves suitable for sildenafil; 504 men (39.6%) deemed themselves unsuitable; and 254 (19.9%) were unsure. The concordance rate between screener-assessed suitability and self-assessed suitability was 70.9% (95% confidence interval [CI] = 68.1-73.7%). When accounting for men who would not take sildenafil even though they were suitable or would seek additional information from a healthcare professional prior to using sildenafil, the concordance rate was 84.2% (95% CI = 82.2-86.2%). The results of this study suggest that men in the general population are capable of using written sildenafil patient education materials to accurately assess

Full Text Available INTRODUCTION: In vitro hydrodynamic characterization of prosthetic heart valves provides important information regarding their operation, especially if performed by noninvasive techniques of anemometry. Once velocity profiles for each valve are provided, it is possible to compare them in terms of hydrodynamic performance. In this first experimental study using laser doppler anemometry with mechanical valves, the simulations were performed at a steady flow workbench. OBJECTIVE: To compare unidimensional velocity profiles at the central plane of two bi-leaflet aortic prosthesis from St. Jude (AGN 21 - 751 and 21 AJ - 501 models exposed to a steady flow regime, on four distinct sections, three downstream and one upstream. METHODS: To provide similar conditions for the flow through each prosthesis by a steady flow workbench (water, flow rate of 17L/min. and, for the same sections and sweeps, to obtain the velocity profiles of each heart valve by unidimensional measurements. RESULTS: It was found that higher velocities correspond to the prosthesis with smaller inner diameter and instabilities of flow are larger as the section of interest is closer to the valve. Regions of recirculation, stagnation of flow, low pressure, and flow peak velocities were also found. CONCLUSIONS: Considering the hydrodynamic aspect and for every section measured, it could be concluded that the prosthesis model AGN 21 - 751 (RegentTM is superior to the 21 AJ - 501 model (Master Series. Based on the results, future studies can choose to focus on specific regions of the these valves.

New media technologies (computers, mobile phones and the internet) have the potential to transform the healthcare information needs of patients with breast disease (Ferlay et al. in Eur J Cancer 49:1374-1403, 2013). However, patients' current level of use and their willingness to accept new media for education and communication remain unknown. This was a single-centre clinic-based prospective cross-sectional study. A previously developed instrument was modified, validated and tested on patients attending a symptomatic breast clinic. The instrument was evaluated on 200 symptomatic breast patients. The commonest outlets for education were staff (95 %), leaflets (69 %) and websites (59 %). Websites are more likely to be consulted by younger patients (higher education were more likely to favour apps, websites and email (p technology use among breast patients is expanding as expected along generational trends. As such its' further integration into healthcare systems can potentially ameliorate patient education and communication.

Full Text Available Through the urine test we can measure kidney function and identify pathologies of the urinary tract. The urine test strips are a fast, easy and increasingly used method of analysis. It is extremely important to check compatibility between the different brands assuring a better understanding of the diagnosis. We compared the package inserts of eight different brands of urine test strips and the reagents used in the urinary determination, besides information concerning the detection of limit ranges, reading intervals and possible interferences. A comparison of the leaflets showed differences among them. Concerning the reagents used, in general, all brands use similar ones but in different quantities. The patient information leaflets have several interferences, but it was observed that some brands do not mention the interferences that are mentioned in other brands. As for the legends of semiquantitative measurements, most brands do not include this information on the product leaflet. Among the brands that could be analyzed with this parameter was observed that the analytes glucose, bilirubin, ketones and blood did not have the same correlation between concentration and label brands. We stress the importance of ensuring a greater standardization of the information contained in the leaflets of the reagent strips.

Understanding the informational needs of cancer patients is a requirement to plan any educative care program for them. The aim of this study was to identify Iranian cancer patients' perceptions of informational needs. The study took a qualitative approach. Semi-structured interviews were held with 25 cancer patients in two teaching hospitals in Iran. Transcripts of the interviews underwent conventional content analysis, and categories were extracted. The results came under two main categories: disease-related informational needs and information needs related to daily life. Disease-related informational needs had two subcategories: obtaining information about the nature of disease and obtaining information about disease prognosis. Information needs related to daily life also had two subcategories: obtaining information about healthy lifestyle and obtaining information about regular activities of daily life. The findings provide deep understanding of cancer patients' informational needs in Iran.

In response to the dearth of consumer health information for patients with gastrointestinal cancers, this study examined the informational needs of these patients to build a plan for future resource development. Although studies have examined informational needs of some such cancers, no published literature has investigated the comprehensive informational needs across all sites of gastrointestinal cancer. A cross-sectional needs assessment comprising a self-administered questionnaire was conducted at an ambulatory gastrointestinal oncology clinic in Toronto, Canada. Patient informational needs were measured, including importance of information, amount desired and preferred mode of delivery. Informational needs were grouped into six domains: medical, practical, physical, emotional, social and spiritual. Eighty-two surveys were analysed. The majority of the respondents were male (53.8%), over the age of 50 (77.8%), and born outside of Canada (51.9%). While many did not speak English as a child (46.3%), and do not speak English at home (22.2%), nearly all indicated comfort with receiving health information in English (97.5%). The majority of respondents were college educated (79.3%) and married (73%). Multiple cancer types were reported; the most common being colorectal (39%), followed by pancreatic (12%) and cancers of the gallbladder or bile duct (12%). Overall, respondents placed highest importance on medical information (P < 0.001). Preferred education modalities were pamphlets, websites and one-on-one discussions with health-care professionals. This study highlights the principal informational needs of patients with gastrointestinal malignancies, along with preferred modality for information delivery. This information will guide the development of educational resources for future patients. © 2014 John Wiley & Sons Ltd.

To estimate the prevalence of limited health literacy in patients receiving clozapine for schizophrenia. To develop and produce a pharmacist-designed clozapine patient information leaflet (PIL) which has a higher readability score than the company-produced PIL. This was a cross sectional prevalence study. Ethical approval for the study was granted by the local ethics committee. Patients, over 18 years, attending the Clozapine Clinic of a Cork urban teaching hospital, were asked to participate in the study. Demographics such as gender, age, employment and smoking status, were gathered from all participants. The total daily clozapine dose, duration of clozapine treatment, and information regarding the clozapine DVD was also noted. The Rapid Estimate of Adult Literacy in Medicine (REALM) health literacy (HL) screening tool was then administered to each patient. A user-friendly PIL on clozapine was designed by the pharmacist, which was assessed for readability and compared to the company-produced PIL using the FRES and FKGL. Data were analysed using SPSS Version 15. Forty patients (65% male, 95% unemployed and 70% smokers) of average age 38.0 years (+/- 11.2) completed the REALM. The average score was 60.6 (+/- 8.7). Twenty-nine patients (72.5%) were found to have "adequate" health literacy. The remaining eleven patients were found to have either "marginal" or "low" health literacy. The pharmacist-designed PIL would have been readable by 95% of the study population, in contrast to 72.5% with the company-designed PIL. More than a quarter of the population were found to have marginal or low health literacy. Patient information should be matched to the health literacy level of the target population.

Full Text Available Background: A paucity of data exists regarding the prevalence and relationship of hypomagnesaemia with clinical symptoms of mitral valve prolapse (MVP in pediatric patients. Objective: In this study we evaluated the prevalence of magnesium (Mg deficiency in pediatric patients with MVP syndrome and attempted to clarify the effect of Mg therapy on alleviating their symptoms. Methods: The present study was conducted from April 2010 to January 2012, and included 230 patients (90 males and 140 females with symptoms of mitral valve prolapse and mean age of 11.6±3.66. Serum magnesium (Mg level less than 1.5 mg/dl was defined as hypomagnesaemia. Patients with 2 mm leaflet displacement and maximum leaflet thickness of 5 mm in echocardiography were considered to have classic MVP, while those with leaflet thickness less than 5 mm were considered as non-classic MVP. Patients with hypomagnesaemia were orally treated with 4.5 mg/kg/day Mg chloride for 5 weeks followed by re-evaluation of symptoms of chest pain, palpitation, fatigue and dyspnea. Results: Hypomagnesaemia was found in 19 (8.2 % of 230 patients with mitral valve prolapse. The re-evaluation of patients with Hypomagnesaemia after 5 weeks of Mg therapy, showed statistically significant relief of chest pain (P=0.01. However, no significant changes was detected in regard to palpitation (P=0.06, fatigue (P= 0.5 and dyspnea (P=0.99. Conclusion: This study revealed that the prevalence of hypomagnesaemia in pediatric patients with mitral valve prolapse is relatively low compared to adults, but treatment with oral Mg in patient with hypomagnesaemia decreases chest pain.

A few studies have examined the specific informational needs of the population with amyotrophic lateral sclerosis. The aims of this study were to describe the information-seeking behavior and information needs of patients with amyotrophic lateral sclerosis and their families in Korea by analyzing messages from an online patient community. A total of 1047 messages from the question and answer forum of the "Lou Gehrig's Disease Network" (http://cafe.daum.net/alsfree) from January 2010 to September 2015 were collected. The word frequency, main questions, and asker of the messages were analyzed and coded. Terms such as "hospital," "mother," "father," "gastrostomy," and "ALS" were most frequently identified. The most commonly mentioned main topic was about disease-specific information, while the most frequent subcategory was symptoms or management of symptoms. Other prominent categories concerned information about treatment, rehabilitation, and the medical system. The people who wrote the questions were mostly the son/daughter of patients with amyotrophic lateral sclerosis. Patients with amyotrophic lateral sclerosis and their family members commonly obtained information by posting their inquiries online and have a variety of questions regarding amyotrophic lateral sclerosis in this study. The findings of this study can be used as a base of information for developing educational programs and resources for patients with amyotrophic lateral sclerosis and their families.

Full Text Available Abstract Despite remarkable developments in the use of surgical techniques, ergonomic advancements in the operating room, and implementation of bundles, surgical site infections (SSIs remain a substantial burden, associated with increased morbidity, mortality and healthcare costs. National and international recommendations to prevent SSIs have been published, including recent guidelines by the World Health Organization, but implementation into clinical practice remains an unresolved issue. SSI improvement programs require an integrative approach with measures taken during the pre-, intra- and postoperative care from the numerous stakeholders involved. The current SSI prevention strategies have focused mainly on the role of healthcare workers (HCWs and procedure related risk factors. The importance and influence of patient participation is becoming an increasingly important concept and advocated as a means to improve patient safety. Novel interventions supporting an active participative role within SSI prevention programs have not been assessed. Empowering patients with information they require to engage in the process of SSI prevention could play a major role for the implementation of recommendations. Based on available scientific evidence, a panel of experts evaluated options for patient involvement in order to provide pragmatic recommendations for pre-, intra- and postoperative activities for the prevention of SSIs. Recommendations were based on existing guidelines and expert opinion. As a result, 9 recommendations for the surgical patient are presented here, including a practice brief in the form of a patient information leaflet. HCWs can use this information to educate patients and allow patient engagement.

Mean age of the patients was 44 ± 15.3 years (84% females). Acute rheumatic fever was rare. Hypertension and HIV were present in 52 and 26%, respectively. Echocardiography showed leaflet thickening and calcification, restricted motion and subvalvular disease in 41, 25 and 34%, respectively. Carpentier IIIa leaflet dysfunction occurred in 80% of patients and leaflet prolapse was seen in only 20%. These findings contrast with the previous literature, where patients were younger, they had rheumatic carditis and there were no co-morbidities. Leaflets were pliable, isolated leaflet prolapse was common and commissural fusion was absent. Contemporary patients with rheumatic MR were older, fewer had rheumatic fever and there were more co-morbidities. Echocardiographic features had evolved to greater leaflet thickening, calcification and reduced motion with minimal prolapse. These findings may have important implications for surgical management of this disease.

Patients want to know more about their condition and its proposed treatment. Gaining patients' confidence before treatment reduces the changes of their seeking legal redress for an unexpected outcome. As part of a prospective study of informed consent for surgery we have assessed the attitudes of patients towards informed consent when different types of consent interview are used. We found that most patients are happy to do as their doctor advises but think the informal consent interview is important because it gives them information; they also want to know about most, but not all, complications of the procedure. One quarter worried about the anaesthetic, about one eighth worried about 'not waking up' and similar proportions worried about complications and other things such as pain and nausea. Most patients think that the consent form is a legal document. In addition patients who had an informal interview felt obliged to sign the consent form and thought it had medicolegal implications. In contrast those who had a structured interview felt less obliged to sign the consent form and more involved in the decision to operate.

Full Text Available Background: Knowledge of correct information-seeking behavior by the patients can provide health specialists and health information specialists with valuable information in improving health care. This study aimed to investigate the passive receipt and active seeking of health information by diabetic patients. Materials and Methods: A survey method was used in this research on 6426 diabetic patients of whom 362 patients were selected by a no percentage stratified random sampling. The Longo information-seeking behavior questionnaire was used to collect data and they were analyzed by SPSS 20 software. Results: The most common information source by diabetic patients was practitioners (3.12. The minimum usage among the information sources were from charity organizations and emergency phone lines with a usage of close to zero. The amount of health information gained passively from each source has the lowest average of 4.18 and usage of this information in making health decision has the highest average score of 5.83. Analysis of the data related to active seeking of information showed that knowledge of available medical information from each source has the lowest average score of 3.95 and ability in using the acquired information for making medical decisions has the highest average score of 5.28. The paired t-test showed that differences between passive information receipt (41.68 and active information seeking (39.20 considered as statistically significant (P < 0.001. Conclusion: Because diabetic patients are more passive information receivers than active information seekers, the health information must be distributed by passive means to these patients. In addition, information-seeking behavior during different time periods should be investigated; to identify more effective distribution of health information.

(a) To find out how much patient information material on display in family physicians' offices refers to management choices, and hence may be useful to support informed and shared decision-making (ISDM) by patients and (b) to evaluate the quality of print information materials exchanged during the consultation, i.e. brought in by patients or given out by family physicians. All print information available for patients and exchanged between physicians and patients was collected in a single complete day of the office practices of 21 family physicians. A published and validated instrument (DISCERN) was used to assess quality. Community office practices in the greater Vancouver area, British Columbia, Canada. The physicians were purposefully recruited by their association with the medical school Department of Family Practice, their interest in providing patients with print information and their representation of a range of practice types and location. The source of the pamphlets and these categories: available in the physicians' offices; exchanged between physician and patient; and produced with the explicit or apparent intent to support evidence-based patient choice. The quality of the print information to support ISDM, as measured by DISCERN and the ease of use and reliability of the DISCERN tool. Fewer than 50% of pamphlets available in these offices fulfilled our minimum criteria for ISDM (mentioned more than one management option). Offices varied widely in the proportion of pamphlets on display that supported ISDM and how particular the physician was in selecting materials. The DISCERN tool is quick, valid and reliable for the evaluation of patient information. The quality of patient information materials used in the consultation and available in these offices was below midpoint on the DISCERN score. Major deficiencies were with respect to the mention of choices, risks, effect of no treatment or uncertainty and reliability (source, evidence-base). Good quality

Provision of information to patients and families is a priority of palliative care. Lack of information on symptoms, treatment and disease progress adversely affects patients' and caregivers' abilities to self manage and participate in decision making and care. Qualitative reports of end of life care suggest caregivers seek more information than patients. Ignorance of this need may hamper health promotion strategies and limitation of patient and caregiver morbidity during end of life and bereavement processes. To compare satisfaction of dying patients with information given; to proxy satisfaction estimates on the patient's behalf. Prospective study comparing assessment of satisfaction with information received by nurse, informal caregiver and dying patient (>64 years) in hospital. Assessments made within 24 h, using patient and caregiver versions of the palliative outcome scale (POS). weighted kappa for agreement between proxy and patient. Informal caregivers overestimate dissatisfaction with level of information given compared to patients. Weighted kappa patient versus ICG 0.187 (slight agreement), n = 50. The disparity between patient and proxy information satisfaction reflects the complexity of participatory strategies to limit morbidity at the end of life. Proxy over- estimation of patient dissatisfaction with information received may reflect the caregivers own dissatisfaction. As death approaches, caregivers require more information than patients, their burden increases and they become the interpreter of patient symptoms. Ignorance may lead to overestimation of symptoms, early breakdown of social care, and unplanned admission, risking death other than in the patients preferred place. Meeting caregiver information needs may reduce caregiver burden and improve proxy assessments, reducing patient and caregiver morbidity. © 2015, Published by the BMJ Publishing Group Limited.

The role of patients as key contributors in pharmacovigilance was acknowledged in the new EU pharmacovigilance legislation. This contains several efforts to increase the involvement of the general public, including making patient adverse drug reaction (ADR) reporting systems mandatory. Three years have passed since the legislation was introduced and the key question is: does pharmacovigilance yet make optimal use of patient-reported safety information? Independent research has shown beyond doubt that patients make an important contribution to pharmacovigilance signal detection. Patient reports provide first-hand information about the suspected ADR and the circumstances under which it occurred, including medication errors, quality failures, and 'near misses'. Patient-reported safety information leads to a better understanding of the patient's experiences of the ADR. Patients are better at explaining the nature, personal significance and consequences of ADRs than healthcare professionals' reports on similar associations and they give more detailed information regarding quality of life including psychological effects and effects on everyday tasks. Current methods used in pharmacovigilance need to optimise use of the information reported from patients. To make the most of information from patients, the systems we use for collecting, coding and recording patient-reported information and the methodologies applied for signal detection and assessment need to be further developed, such as a patient-specific form, development of a severity grading and evolution of the database structure and the signal detection methods applied. It is time for a renaissance of pharmacovigilance.

[Drug advertising--users want information. Report of telephone survey conducted by North-Rhine Westphalia Public Health Service on the topic of drug advertising and drug information for users].

In Germany, drug advertising of non-prescription drugs is a controversial subject. On the one hand, consumer organisations plead for placing a ban on advertising or at least to offer a detailed description of medical risks in respect of protection. On the other hand, the pharmaceutical industry is keen on liberalizing the specific advertising law for drugs. A representative telephone survey among the population of North Rhine-Westphalia was conducted in April and May 1999. It showed consumer interest in advertising, the value of information on risks, the institution with maximum credibility in drug information for consumers, the importance of the now obligatory sentence after every advertisement: Regarding risks and side effects read the leaflet in the package and ask your physician or pharmacist, and to what extend the consumer would take advice from independent experts over the telephone about drugs. It was found that, in particular women, about 30% are occasionally interested in advertising, younger people are more open-minded about advertising than older people; and that doctors and pharmacists have the most credibility and are consulted for further information. It was also found that more than 80% of the population demanded precise information on the side effects of drugs. One-third of the consumers declared that the obligatory sentence (see above) led to greater demand for information from doctors or to read attentively the instruction leaflet. Nevertheless, there is a need for more information from more than half of the consumers, who would take advantage of an independent advice centre if this should exist.

Internet health information in the patient-provider dialogue.

A patient discussing Internet health information with a health care provider (referred to as "patient-provider communication about Internet health information") can contribute positively to health outcomes. Although research has found that once Internet access is achieved, there are no ethnic differences in Internet health information seeking, it is unclear if there are ethnic differences in patient-provider communication about Internet health information. To help fill this gap in the literature, the National Cancer Institute's Health Information National Trends Survey 2005 was analyzed with Stata 9. Two sets of logistic regression analyses were conducted, one for a subsample of Internet users (n = 3,244) and one for a subsample of Internet users who are first-generation immigrants (n = 563). The dependent variable was patient-provider communication about Internet health information, which assessed whether survey participants had discussed online health information with a health care provider. The predictor variables included trust of health care provider, trust of online health information, Internet use, health care coverage, frequency of visits to health care provider, health status, and demographics. Among all Internet users, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. Similarly, among Internet users who are immigrants, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. While the digital divide is narrowing in terms of Internet access, racial differences in patient-provider communication about Internet health information may undermine the potential benefits of the information age.

To evaluate the quality of the information provided by informed consent forms for angiography and interventional radiology on the basis of the patients opinion. A descriptive study was performed based on an anonymous survey distributed among patients who were to undergo angiography and interventional radiology, and had previously been informed and provided with the corresponding informed consent form. A descriptive and analytical statistical study was carried out to compare the responses to the questions concerning different factors (Mann-Whitney U test). Of the 182 surveys completed 75.3% corresponded to diagnostic procedures and the remaining 24.7% to therapeutic procedures. When the responses to closed-ended questions were analyzed, 90.1% of respondents considered the amount of information provided by the document to be sufficient 75.3% declared that they found the form easy to comprehend and 34.1% responded that reading it had calmed their nerves. Statistically significant differences were observed, depending on whether the form corresponded to diagnostic or therapeutic procedures, concerning the questions related to comprehension of the document and to the feeling upon reading it, with those used for diagnostic procedures obtaining better scores. There was a statistically significant difference between the responses of the patients to the question concerning their feeling upon reading the document and the responses of family members, with the patients responding more favorably than their relatives. The consent forms prepared for angiography and interventional radiology procedures are acceptable to the patients concerned with respect to both the quantity and the quality of the information.

Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient's values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge the information needs of the individual patient. The aim of this paper is to describe 'core information sets' which are defined as a minimum set of consensus-derived information about a given procedure to be discussed with all patients. Importantly, they are intended to catalyse discussion of subjective importance to individuals. The model described in this paper applies health services research and Delphi consensus-building methods to an idea orginally proposed 30 years ago. The hypothesis is that, first, large amounts of potentially-important information are distilled down to discrete information domains. These are then, secondly, rated by key stakeholders in multiple iterations, so that core information of agreed importance can be defined. We argue that this scientific approach is key to identifying information important to all stakeholders, which may otherwise be communicated poorly or omitted from discussions entirely. Our methods apply systematic review, qualitative, survey and consensus-building techniques to define this 'core information'. We propose that such information addresses the 'reasonable patient' standard for information disclosure but, more importantly, can serve as a spring board for high-value discussion of importance to the individual patient. The application of established research methods can define information of core importance to informed consent. Further work will establish how best to incorporate

A marked knowledge gap exists concerning the information needs of hepato-pancreato-biliary (HPB) surgical oncology patients. We investigated the comprehensive information needs of this patient population, including the type and amount of information desired, as well as the preferred method of receiving information. A questionnaire was administered to patients being treated surgically for cancers of the liver, pancreas, gallbladder, or bile ducts at Toronto General Hospital, part of the University Health Network, in Toronto, Canada. The questionnaire examined patients' information needs across six domains of information: medical, practical, physical, emotional, social, and spiritual. Among 36 respondents, the importance of information and amount of information desired differed significantly by domain (both p < 0.001). This group of patients rated information in the medical and physical domains as most important, though they also desired specific items of information from the emotional, practical, and social domains. Patients' overwhelming preference was to receive information via a one-on-one consultation with a healthcare provider. It is important for healthcare providers working with HPB surgical oncology patients to be comprehensive when providing information related to patients' cancer diagnosis, prognosis, associated symptoms, and side effects of treatment. Certain emotional, practical, and social issues (e.g., fears of cancer recurrence, drug coverage options, relationship changes) should be addressed as well. Face-to-face interactions should be the primary mode of delivering information to patients. Our findings are being used to guide the training of healthcare providers and the development of educational resources specific to HPB surgical oncology patients.

Full Text Available Abstract Background Lyme disease or Lyme borreliosis (LB is the most common tick-borne disease both in the United States and Europe. Children, in particular, are at high risk of contracting LB. Since child-specific educational tools on ticks, tick bites and LB are lacking, we developed an online educational video game. In this study, we compared the effectiveness of an online educational video game versus a newly developed leaflet aimed to improve prevention of tick bites and LB among Dutch schoolchildren. Methods A total of 887 children, aged 9–13 years and attending the two final years of primary schooling, were recruited from 25 primary schools in June and July 2012. They were assigned through cluster randomization to one of three intervention groups: ‘game’ (22.4%, ‘leaflet’ (35.6% or ‘control’ (41.9%. Prior to and directly following intervention, the children were asked to complete a short questionnaire. The main outcome measures were knowledge, perception (perceived susceptibility and importance and preventive behavior in relation to tick bites and LB. Generalized linear mixed models were used to analyze the data. Results In the game group, the leaflet group and the control group, knowledge about ticks and tick bites improved significantly. The game was also an effective tool for improving preventive behavior; the frequency of checking for ticks increased significantly. However, there were no significant differences in knowledge improvement between the interventions. The game outperformed the leaflet in terms of improving preventive behavior, whereas the frequency of tick checks increased significantly. But this frequency didn’t increase more than in the control group. Conclusions The positive knowledge effects observed in the control group suggests the presence of a mere measurement effect related to completion of the questionnaire. The game did not outperform the leaflet or control group on all outcome measures. Therefore

The purpose of this study was to determine the information needs of primary care patients as they review clinic visit notes to inform information that should be contained in an after-visit summary (AVS). We collected data from 15 patients with an acute illness and 14 patients with a chronic disease using semi-structured interviews. The acute patients reviewed seven major sections, and chronic patients reviewed eight major sections of a simulated, but realistic visit note to identify relevant information needs for their AVS. Patients in the acute illness group identified the Plan, Assessment and History of Present Illness the most as important note sections, while patients in the chronic care group identified Significant Lab Data, Plan, and Assessment the most as important note sections. This study was able to identify primary care patients' information needs after clinic visit. Primary care patients have information needs pertaining to diagnosis and treatment, which may be the reason why both patient groups identified Plan and Assessment as important note sections. Future research should also develop and assess an AVS based on the information gathered in this study and evaluate its usefulness among primary care patients. The results of this study can be used to inform the development of an after-visit summary that assists patients to fully understand their treatment plan, which may improve treatment adherence.

Information received by cancer patients has gained importance in recent decades. The aim of this study was to evaluate the perception of information received by oncological patients in a radiotherapy department and to measure the importance of the other information sources. A cross-sectional study was conducted, evaluating patients who received radiotherapy. All the patients were asked two questionnaires: the EORTC QLQ-INFO26 module evaluating their satisfaction with received information, and a questionnaire analyzing other sources of information search. One hundred patients between 27 and 84 years were enrolled. Breast cancer (26 %) was the commonest cancer. Patients felt better informed about the medical tests and secondly about the performed treatment. The younger patients were those who were more satisfied with the information received and patients with no formal education felt less satisfied, with statistically significant differences. Patients did not seek external information; at the most, they asked relatives and other people with cancer. Patients were satisfied with the received information, although a high percentage would like more information. In general, patients did not search for external information sources. Age and educational level seem to influence in the satisfaction with the received information.

To assess how much information communicated to patients is understood and retained after preoperative discussion of upper extremity procedures. A prospective study was designed by recruiting patients prior to undergoing upper extremity surgical procedures after a detailed discussion of their operative technique, postoperative care and treatment outcomes. Patients were given the same 20-item questionnaire to fill out twice, at two pre operative visits. An independent evaluator filled out a third questionnaire as a control. Various discussion points of the survey were compared among the 3 questionnaires and retained information and perceived comprehension were evaluated. The average patients' age was 50.3 (27-75) years The average time between the two surveys preoperative 1 and preoperative 2 was 40.7 (7-75) days,. The average patient had approximately 2 years of college or an associate's degree. Patients initially retained 73% (52-90%) of discussion points presented during preoperative 1 and 61% (36-85%) of the information at preoperative 2 p = .002. 50% of patients felt they understood 100% of the discussion, this dropped to only 10% at their preoperative 2 visit. 15% of our patients did not know what type of anesthesia they were having at preoperative 2. A communication barrier between patients and physicians exists when patients are informed about their preoperative surgical discussion. The retention of information presented is worsened with elapsing time from the initial preoperative discussion to the second preoperative visit immediately prior to surgery. Methods to enhance patients' retention of information prior to surgery must be sought and implemented which will improve patients' treatment outcome.

Despite the chronic and relapsing nature of inflammatory bowel diseases (IBD), at least 30% to 45% of the patients are noncompliant to treatment. IBD patients often seek information about their disease. To examine the association between information-seeking activity and treatment compliance among IBD patients. To compare information sources and concerns between compliant and noncompliant patients. We used data from the Swiss IBD cohort study, and from a qualitative survey conducted to assess information sources and concerns. Crude and adjusted odds ratios (OR) for noncompliance were calculated. Differences in the proportions of information sources and concerns were compared between compliant and noncompliant patients. A total of 512 patients were included. About 18% (n = 99) of patients were reported to be noncompliant to drug treatment and two-thirds (n = 353) were information seekers. The OR for noncompliance among information seekers was 2.44 (95%CI: 1.34-4.41) after adjustment for confounders and major risk factors. General practitioners were 15.2% more often consulted (p = 0.019) among compliant patients, as were books and television (+13.1%; p = 0.048), whereas no difference in proportions was observed for sources such as internet or gastroenterologists. Information on tips for disease management were 14.2% more often sought among noncompliant patients (p = 0.028). No difference was observed for concerns on research and development on IBD or therapies. In Switzerland, IBD patients noncompliant to treatment were more often seeking disease-related information than compliant patients. Daily management of symptoms and disease seemed to be an important concern of those patients.

Pellisé, Ferran; Sell, P

2009-08-01

The role of the patient as an active partner in health care, and not just a passive object of diagnostic testing and medical treatment, is widely accepted. Providing information to patients is considered a crucial issue and the central focus in patient educational activities. It is necessary to educate patients on the nature of the outcomes and the benefits and risks of the procedures to involve them in the decision-making process and enable them to achieve fully informed consent. Information materials must contain scientifically reliable information and be presented in a form that is acceptable and useful to patients. Given the mismatch between public beliefs and current evidence, strategies for changing the public perceptions are required. Traditional patient education programmes have to face the potential barriers of storage, access problems and the need to keep content materials up to date. A computer-based resource provides many advantages, including "just-in-time" availability and a private learning environment. The use of the Internet for patient information needs will continue to expand as Internet access becomes readily available. However, the problem is no longer in finding information, but in assessing the credibility and validity of it. Health Web sites should provide health information that is secure and trustworthy. The large majority of the Web sites providing information related to spinal disorders are of limited and poor quality. Patient Line (PL), a patient information section in the Web site of Eurospine, was born in 2005 to offer patients and the general population the accumulated expertise represented by the members of the society and provide up-to-date information related to spinal disorders. In areas where evidence is scarce, Patient Line provides a real-time opinion of the EuroSpine membership. The published data reflect the pragmatic and the common sense range of treatments offered by the Eurospine membership. The first chapters have been

This study was conducted to develop a self-management program using goal setting for patients after a stroke. The program was based on a theory-based Goal setting and Action Planning framework (G-AP), and the effectiveness of the program was examined. A non-equivalent control group pretest-posttest design was used. The experimental group (n=30) received the self-management program using goal setting based on the G-AP over 7 weeks. The education was delivered individually with a specifically designed stroke workbook. The control group (n=30) received only patient information leaflets about stroke. There were significant differences between the two groups. Stroke knowledge, self-efficacy, and health behavior compliance were significantly higher (all pgoal setting based on a G-AP was found to be useful and beneficial for patients in stroke rehabilitation settings.

Calcification currently represents a major cause of failure of biological tissue heart valves. It is a complex phenomenon influenced by a number of biochemical and mechanical factors. Recent advances in material science offer new polymers with improved properties, potentially suitable for synthetic leaflets heart valves manufacturing. In this study, the calcification-resistance efficacy and mechanical and surface properties of a new nanocomposite polymeric material (polyhedral oligomeric silsesquioxane-poly(carbonate-urea)urethane; POSS-PCU) which has been developed by our group are assessed by means of in vitro testing. In particular, thin sheets of nanocomposite, glutaraldehyde-fixed bovine pericardium (BP) and polyurethane (PU) were exposed to a calcium solution into a specially designed in vitro accelerated physiological pulsatile pressure system for a period of 31days and a total of 4×10(7) cycles. The samples were investigated for signs of calcification after exposure to calcium solution by means of X-ray, microscopic and chemical inspections. Mechanical and surface properties were also studied using stress-strain behaviour and surface morphology and hydrophobicity. Comparison shows that, in the experimental conditions, the level of calcification for the nanocomposite is considerably lower than for the fixed BP (p=0.008) and PU samples (p=0.015). Also, mechanical properties were unchanged in POSS-PCU, while there was a significant deterioration in PU samples (pnanocomposite remained more hydrophobic than the PU sample (pnanocomposite in synthetic leaflets heart valves may lead to potential advantages in terms of long-term performances and durability.

Objective: Knowledge, information and communication, within oncology, are a core clinical strength for the out-come of the disease and inadequate communication, can cause distress for the patient and their families. Design: A senior doctor conducted this study by filling in the performa after interviewing the subject of the study. Place and duration of study: This study was done in Oncology Department of Service Hospital, Lahore and was completed in four months. Subjects and Method: One hundred cancer patients were interviewed regarding their knowledge about their disease, its causes, prognosis, and information supplied by the health-care providers. They were also asked about their satisfaction regarding this information, deficiencies and pitfalls in this information, need for more information, which should supply the information from among the hospital team or their relative, attitude of the family and their communication regarding the disease. Results: Study revealed that the knowledge about the disease and its causes was present in 53% and 7% respectively. The patients (59%) wanted more information. Majority perceived that the information was not adequate and needed more information and 68% thought that more information would reduce their anxiety. The attitude of family was found encouraging in 87% of patients and 42% were communicating with other family members regarding their diseases. Conclusion: Knowledge about the disease and its cause should be increasingly supplied by the doctors, as it will reduce the anxiety and have a good effect on health. Communication among the family members needs to be improved. (author)

Valve-sparing root replacement is increasingly used to overcome drawbacks associated with valvular prostheses. In our institution, 7 patients underwent valve-sparing root replacement from August 2016 to July 2017. The mean age was 45 years (range, 14~69 years). Three patients had Marfan syndrome and 1 had Loeys-Dietz syndrome with acute aortic dissection. All patients underwent surgery with reimplantation technique using a Valsalva graft. Two patients required repair of aortic valve leaflet prolapse. All patients had an excellent clinical course, with mild or no aortic regurgitation and a decrease in end-diastolic volume on echocardiography. These results support the continued use of valve-sparing root replacement in selected patients.

Given the poor prognosis of esophageal cancer and the impact of surgery on health-related quality of life (HRQL), addressing patients' postoperative information needs is important. This study aimed to examine (1) the content and type of patients' information needs and (2) patient perceived facilitators and barriers to patient participation. Interviews were conducted with 20 purposefully selected esophageal cancer patients. Open and structured questions were alternated. The transcribed interviews were analysed inductively and deductively, using MAXqda. Patients' post-operative information needs concerned HRQL, medical care and prognosis, covering several sub-domains. Different types of needs were identified, e.g., requests for information about cause, course and self-management. Barriers to patient participation mostly reflected beliefs and skills, and could be categorized into agenda and communication barriers. Facilitators of patient participation reflected physician, patient and interaction characteristics, companion support and pre-visit preparation. Many patients saw merit in pre-visit preparation interventions; few endorsed skill-building interventions. This study listed the postoperative information needs of esophageal cancer patients. Moreover, it gained insight into patient-perceived barriers and facilitators of patient participation. The findings demonstrate what information physicians should have available and informs interventions to support patients in meeting their information needs. Copyright © 2011 Elsevier Ireland Ltd.

Ukkola, L.; Oikarinen, H.; Henner, A.; Haapea, M.; Tervonen, O.

2017-01-01

Introduction: It is suspected that little or no information is provided to patients regarding radiological examinations. The purpose was to evaluate the coverage, content and source of this information in a university hospital. Methods: Altogether 147 patients (18–85 years) were interviewed after different examinations using a questionnaire. The patients had undergone 35 low (<1 mSv), 66 medium (1–10), and 46 high (>10) dose examinations. They were asked if they were informed about radiation use, the course or indication of the examination, the consequences of not having the examination, other options, the dose and risks of radiation, the source for the information and if any consent was enquired. Results: 52 (35%) patients did not receive any information while 95 (65%) obtained some information. Fifty-six (38%) patients received an information letter, and 75 (51%) obtained oral information, mainly from the referrer or the radiographer. The information was mostly about indication, course or radiation use, very seldom about radiation risks and the other areas. Those with a nuclear medicine examination received information more often than those with other medium- or high-dose examinations (p = 0.004). The patients scored the received information as 2.2 (mean, SD 1.3) on a Likert scale from 1 (poor) to 5 (good). Conclusion: Patients obtained inadequate information regarding radiological examinations in a university hospital. The information was provided non-systematically from various sources. The results help to set up practical guidelines for systematic information and to follow up their efficiency. The mode of operation might be helpful elsewhere in the future. - Highlights: • Patients obtained inadequate information regarding medical radiation exposure. • The information was provided non-systematically from various sources. • Patients with nuclear examinations were informed better than with other modalities. • In addition to general guidelines

Informing patients of risks inherent in treatment.

Consent to treatment lies at the heart of autonomous decision making by patients who are entitled to make a free choice about whether to accept or refuse treatment. To help patients arrive at their decision district nurses must ensure that they give sufficient information about the nature and risks inherent in the treatment to allow an informed choice to be made. This article considers how much information regarding risks needs to be disclosed. It discusses how the law requires a different level of disclosure for patients who ask no questions about risks, those who make general enquiries about risks and those who ask specific questions about the risks inherent in treatment.

Recent research focused on online health information seeking highlights a heavy reliance on general-purpose search engines. However, current general-purpose search interfaces do not necessarily provide adequate support for non-experts in identifying suitable sources of health information. Popular search engines have recently introduced search tools in their user interfaces for a range of topics. In this work, we explore how such tools can support non-expert, patient-centered health information search. Scoping the current work to medication-related search, we report on findings from a formative study focused on the design of patient-centered, medication-information search tools. Our study included qualitative interviews with patients, family members, and domain experts, as well as observations of their use of Remedy, a technology probe embodying a set of search tools. Post-operative cardiothoracic surgery patients and their visiting family members used the tools to find information about their hospital medications and were interviewed before and after their use. Domain experts conducted similar search tasks and provided qualitative feedback on their preferences and recommendations for designing these tools. Findings from our study suggest the importance of four valuation principles underlying our tools: credibility, readability, consumer perspective, and topical relevance.

Patient decision making in the face of conflicting medication information

Directory of Open Access Journals (Sweden)

Emily Elstad

2012-08-01

Full Text Available When patients consult more than one source of information about their medications, they may encounter conflicting information. Although conflicting information has been associated with negative outcomes, including worse medication adherence, little is known about how patients make health decisions when they receive conflicting information. The objective of this study was to explore the decision making strategies that individuals with arthritis use when they receive conflicting medication information. Qualitative telephone interviews were conducted with 20 men and women with arthritis. Interview vignettes posed scenarios involving conflicting information from different sources (e.g., doctor, pharmacist, and relative, and respondents were asked how they would respond to the situation. Data analysis involved inductive coding to identify emergent themes and deductive contextualization to make meaning from the emergent themes. In response to conflicting medication information, patients used rules of thumb, trial and error, weighed benefits and risks, and sought more information, especially from a doctor. Patients relied heavily on trial and error when there was no conflicting information involved in the vignette. In contrast, patients used rules of thumb as a unique response to conflicting information. These findings increase our understanding of what patients do when they receive conflicting medication information. Given that patient exposure to conflicting information is likely to increase alongside the proliferation of medication information on the Internet, patients may benefit from assistance in identifying the most appropriate decision strategies for dealing with conflicting information, including information about best information sources.

Full Text Available Through an examination of librarians’ contributions to the PEPTalk research project, this article highlights roles for information professionals at various stages in the design and clinical implementation of an information system that delivers patient education. The Personal Education Plan (PEPTalk was a collaborative, multi-disciplinary research project (2005-2006 based at the University Health Network’s Princess Margaret Hospital that designed an information system to provide web-based health information resources to both patients and clinicians under a shared umbrella of patient education. This article provides an overview of the PEPTalk project methods and outcomes, and documents the contributions of librarians throughout the design and clinical implementation stages of the project. Librarians brought expertise about information seeking behaviours of both patients and clinicians to the project; liaised across institutional and professional boundaries; developed a classification system for online learning objects, and educated project team about information and health literacies. The contributions of librarians on the PEPTalk project illustrate the need for boundary spanners, information brokers, knowledge translators, and change champions in the design and implementation of patient education delivery systems. There are new roles emergent at the intersections of clinical practice and health information provision. There is a need for the traditional skills and expertise of librarians and other information professionals in tailoring health information. Yet the design and implementation of patient education systems also require the development of new skills and the application of advanced information literacy as it pertains to both clinicians and patients.

Vortex dynamics in Patient-Specific Stenotic Tricuspid and Bicuspid Aortic Valves pre- and post- Trans-catheter Aortic Valve Replacement

Hatoum, Hoda; Dasi, Lakshmi Prasad

2017-11-01

Understanding blood flow related adverse complications such as leaflet thrombosis post-transcatheter aortic valve implantation (TAVI) requires a deeper understanding of how patient-specific anatomic and hemodynamic factors, and relative valve positioning dictate sinus vortex flow and stasis regions. High resolution time-resolved particle image velocimetry measurements were conducted in compliant and transparent 3D printed patient-specific models of stenotic bicuspid and tricuspid aortic valve roots from patients who underwent TAVI. Using Lagrangian particle tracking analysis of sinus vortex flows and probability distributions of residence time and blood damage indices we show that (a) patient specific modeling provides a more realistic assessment of TAVI flows, (b) TAVI deployment alters sinus flow patterns by significantly decreasing sinus velocity and vorticity, and (c) relative valve positioning can control critical vortex structures that may explain preferential leaflet thrombosis corresponding to separated flow recirculation, secondary to valve jet vectoring relative to the aorta axis. This work provides new methods and understanding of the spatio-temporal aortic sinus vortex dynamics in post TAVI pathology. This study was supported by the Ohio State University DHLRI Trifit Challenge award.

2008-04-01

Full Text Available Abstract Purpose In mitral valve prolapse, determining whether the valve is suitable for surgical repair depends on the location and mechanism of regurgitation. We assessed whether cardiovascular magnetic resonance (CMR could accurately identify prolapsing or flail mitral valve leaflets and regurgitant jet direction in patients with known moderate or severe mitral regurgitation. Methods CMR of the mitral valve was compared with trans-thoracic echocardiography (TTE in 27 patients with chronic moderate to severe mitral regurgitation due to mitral valve prolapse. Contiguous long-axis high temporal resolution CMR cines perpendicular to the valve commissures were obtained across the mitral valve from the medial to lateral annulus. This technique allowed systematic valve inspection and mapping of leaflet prolapse using a 6 segment model. CMR mapping was compared with trans-oesophageal echocardiography (TOE or surgical inspection in 10 patients. Results CMR and TTE agreed on the presence/absence of leaflet abnormality in 53 of 54 (98% leaflets. Prolapse or flail was seen in 36 of 54 mitral valve leaflets examined on TTE. CMR and TTE agreed on the discrimination of prolapse from flail in 33 of 36 (92% leaflets and on the predominant regurgitant jet direction in 26 of the 27 (96% patients. In the 10 patients with TOE or surgical operative findings available, CMR correctly classified presence/absence of segmental abnormality in 49 of 60 (82% leaflet segments. Conclusion Systematic mitral valve assessment using a simple protocol is feasible and could easily be incorporated into CMR studies in patients with mitral regurgitation due to mitral valve prolapse.

Antibiotics are overused in many European countries, particularly Greece, leading to emerging antimicrobial resistance with sustained high mortality among hospitalised patients. Limited data are available regarding factors influencing people's knowledge and the impact of public campaigns on antibiotic misuse. Patients' beliefs regarding antibiotics were investigated in the outpatient clinic of a university hospital in Athens, Greece. A questionnaire-based survey was conducted to examine patients' opinions on antibiotic use in the waiting room of the outpatient clinic. All participants read an illustrated pocket-sized leaflet endorsed by official authorities on the European Antibiotic Awareness Day (EAAD). Volunteers then completed a questionnaire containing information on demographics, knowledge on antibiotic use and overuse, and remarks on the quality of the leaflet's content. In a logistic regression analysis including age, sex, educational level and professional status of 605 eligible participants, women were more aware [odds ratio (OR)=3.2, 95% confidence interval (CI) 1.8-5.8; Peducation were less aware (OR=0.4, 95% CI 0.1-0.9; P=0.04) of antimicrobial misuse. Workers were also more aware than retired or unemployed people (P=0.007). However, only 16.0% of participants knew about the EAAD. All participants agreed on antibiotic misuse in Greece, mentioning patient accountability as the main cause (26.8%), an opinion more pronounced in highly educated individuals. In conclusion, targeted interventions taking into account variations in educational level and employee status should be considered in future scheduled educative campaigns on antibiotic overconsumption in highly prescribing antibiotic countries.

Hutchison, Catherine; McCreaddie, May

2007-11-01

The aim of this project was to produce audiovisual patient information, which was user friendly and fit for purpose. The purpose of the audiovisual patient information is to inform patients about randomized controlled trials, as a supplement to their trial-specific written information sheet. Audiovisual patient information is known to be an effective way of informing patients about treatment. User involvement is also recognized as being important in the development of service provision. The aim of this paper is (i) to describe and discuss the process of developing the audiovisual patient information and (ii) to highlight the challenges and opportunities, thereby identifying implications for practice. A future study will test the effectiveness of the audiovisual patient information in the cancer clinical trial setting. An advisory group was set up to oversee the project and provide guidance in relation to information content, level and delivery. An expert panel of two patients provided additional guidance and a dedicated operational team dealt with the logistics of the project including: ethics; finance; scriptwriting; filming; editing and intellectual property rights. Challenges included the limitations of filming in a busy clinical environment, restricted technical and financial resources, ethical needs and issues around copyright. There were, however, substantial opportunities that included utilizing creative skills, meaningfully involving patients, teamworking and mutual appreciation of clinical, multidisciplinary and technical expertise. Developing audiovisual patient information is an important area for nurses to be involved with. However, this must be performed within the context of the multiprofessional team. Teamworking, including patient involvement, is crucial as a wide variety of expertise is required. Many aspects of the process are transferable and will provide information and guidance for nurses, regardless of specialty, considering developing this

Perspectives of patients with haematological cancer on how clinicians meet their information needs: "Managing" information versus "giving" it.

2018-03-23

Practitioners treating patients with haematological cancers have extensive clinical information available to give to patients, and patients need to be informed. However, many patients want to be protected from having information that is too detailed or threatening. To illuminate how practitioners can address this dilemma and help patients feel appropriately informed, we explored patients' experience of feeling informed or uninformed. Semi-structured interviews were conducted with 20 patients who had been diagnosed with haematological cancer and had recently received results from clinical investigations or from evaluations of treatment response. Inductive and interpretive analysis of the transcribed audio-recorded interviews drew on constant comparison. Patients described the need for practitioners carefully to manage the information that they provided, and many felt alarmed by information that they did not experience as having been managed for them. A few patients who had difficulty trusting practitioners were not content with the information provided. These findings can be understood using attachment theory, whereby practitioners' careful management of information demonstrates their care for patients, and patients' trust in the practitioner enables them to feel informed. It follows that, when patients do not feel informed, the solution will not necessarily be more information but might be to help patients feel more secure in a caring clinical relationship.

The internet is an easy and always accessible source of information for cancer patients. The aim of our study was to evaluate the information provided on German websites. We developed an instrument based on criteria for patient information from the German Network for Evidence-based Medicine, the Agency for Quality in Medicine, HONcode, DISCERN, and the afgis. We simulated a patient's search and derived the websites for evaluation. We analyzed the visibility of each website and evaluated the websites using the developed instrument. We analyzed 77 websites. The highest visibility index was shown by 4 profit websites. Websites from professional societies and self-help groups have low rankings. Concerning quality, websites from non-profit providers and self-help groups are on top. Websites with a profit interest have the lowest average score. A discrepancy exists between the visibility and the quality of the analyzed websites. With the internet becoming an important source of information on cancer treatments for patients, this may lead to false information and wrong decisions. We provide a list of suggestions as to how this risk may be reduced by complementary information from the physician and from trustworthy websites. © 2015 S. Karger GmbH, Freiburg.

Clinical information in drug package inserts in India

2009-01-01

Full Text Available Background: It is widely recognized that accurate and reliable product information is essential for the safe and effective use of medications. Pharmaceutical companies are the primary source of most drug information, including package inserts. Package inserts are printed leaflets accompanying marketed drug products and contain information approved by the regulatory agencies. Studies on package inserts in India, in 1996, had shown that crucial information was often missing and they lacked uniformity. Aim: To assess the presentation and completeness of clinically important information provided in the currently available package inserts in India. Materials and Methods: Package inserts accompanying allopathic drug products marketed by pharmaceutical companies in India were collected. These package inserts were analyzed for the content of clinically important information in various sections. Statistical Analysis: The results were expressed as absolute numbers and percentages. Results: Preliminary analyses revealed that most package inserts did contain information under headings, such as, therapeutic indications, contraindications, undesirable effects, etc., listed in the Drugs and Cosmetics Rules 1945. The findings indicated considerable improvement in package inserts since 1996. However, on critical evaluation it was revealed that clinically important information was not well presented and was often incomplete. Information with regard to pediatric and geriatric use was present in only 44% and 13% of the package inserts, respectively. Only five of the inserts had information on the most frequent adverse drug reactions associated with the drug. Also, information on interactions and overdosage was often missing. Conclusion: Although the package inserts appear to have improved over the past decade there is still a definite need to further refine the clinical information contained, to minimize the risks to patients. This could be brought about by self

Health Information Exchange: What do patients want?

2017-12-01

To determine whether emergency department patients want to share their medical records across health systems through Health Information Exchange and if so, whether they prefer to sign consent or share their records automatically, 982 adult patients presenting to an emergency department participated in a questionnaire-based interview. The majority (N = 906; 92.3%) were willing to share their data in a Health Information Exchange. Half (N = 490; 49.9%) reported routinely getting healthcare outside the system and 78.6 percent reported having records in other systems. Of those who were willing to share their data in a Health Information Exchange, 54.3 percent wanted to sign consent but 90 percent of those would waive consent in the case of an emergency. Privacy and security were primary concerns of patients not willing to participate in Health Information Exchange and preferring to sign consent. Improved privacy and security protections could increase participation, and findings support consideration of "break-the-glass" provider access to Health Information Exchange records in an emergent situation.

Whiplash associated disorders (WAD) result in significant personal and economic costs. Patient education and reassurance are recommended treatments for acute WAD but the information needs of patients have not been investigated. To determine what information whiplash-injured patients believe is important to help recovery in the acute stage of injury. A Delphi design survey series with three rounds. Thirty-three participants who had sustained a whiplash injury within the last three years were invited to participate. Participants were asked to provide five statements, in response to an open-ended question, regarding what they believed was the most important information to provide to patients following a whiplash injury. Nineteen patients responded and 85 statements were collected and reviewed independently by two of the authors to remove duplicates. The importance of the remaining items was rated by the participants in the second survey round. Items rated by >50% of participants as important were included in the third survey round. To be deemed key information, >80% of participants had to rate an item as important in this final round. Eighteen items met the criteria for key information. These points addressed four areas: assessment and treatment, recovery and symptoms, patient attitudes during treatment and relationships with health practitioners. The key information points endorsed by patients in this study may provide useful information to constitute a basis for reassurance and education provided to patients with WAD. The results also suggest that improved relationships between patients with whiplash and health practitioners is required. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although late-onset right-sided heart failure is recognized as a clinical problem in the treatment of patients with left ventricular assist devices (LVADs), the mechanism and predictors are unknown. Tricuspid valve (TV) deformation leads to the restriction of the leaflet motion and decreased coaptation, resulting in a functional tricuspid regurgitation that may act as a surrogate marker of late right-sided heart failure. This study aimed to investigate the association of preoperative TV deformation (annulus dilatation and leaflet tethering) with late right-sided heart failure development after continuous-flow LVAD implantation. The study cohort consisted of 274 patients who underwent 2-dimensional echocardiography before LVAD implantation. TV annulus diameter and tethering distance were measured in an apical 4-chamber view. Late right-sided heart failure was defined as right-sided heart failure requiring readmission and medical and/or surgical treatment after initial LVAD implantation. During a mean follow-up of 25.1 ± 19.0 months after LVAD implantation, late right-sided heart failure occurred in 33 patients (12.0%). Multivariate Cox proportional hazard analysis demonstrated that TV annulus diameter (hazard ratio 1.221 per 1 mm, p right-sided heart failure development, whereas leaflet tethering distance was not. The best cut-off value of the TV annular diameter was 41 mm (area under the curve 0.787). Kaplan-Meier analysis showed that patients with dilated TV annulus (TV annular diameter ≥41 mm) exhibited a significantly higher late right-sided heart failure occurrence than those without TV annular enlargement (log-rank p right-sided heart failure after LVAD implantation.

Increasing numbers of people have turned to the Internet for health information. Little has been done beyond speculation to empirically investigate patients' discussion of online health information with health care professionals (HCPs) and patients' perception of HCPs' reactions to such discussion. The author analyzed data from the 2007 Health Information National Trends Survey (HINTS) to identify the characteristics of patients (a) who search for health information on the Internet, (b) who discuss the information found on the Internet with HCPs, and (c) who positively assess HCPs' reaction to the online information. Findings show that men were more likely than were women to have a conversation on online information with HCPs. It is unfortunate that patients who had trouble understanding or trusting online health information were no more likely to ask questions to or seek guidance from HCPs. Reactions of HCPs to online information were perceived as particularly negative by certain groups of patients, such as those who experienced poor health and those who had more concerns about the quality of their searched information. Results are discussed for their implications for patient empowerment and patient-HCP relationships.

Full Text Available Background. Rupture of papillary muscle generally happens during acute myocardial infarction and is the cause of acute mitral regurgitation, pulmonary oedema, so it should be promptly recognized and managed. Case report. A patient, 52 year-old, was admitted to the Thoracic Department with fever, general weakness, dyspnea and cough as a case of suspected pneumonia. Two days before the admission he was treated with antibiotics. At thoracic ward, his clinical status got serious and he transferred to Intensive Care Unit (ICU as pulmonary oedema. At the time of admission to ICU the patient was seriously ill with tachycardia, tachydyspnea, orthopnea and cyanosis image. Auscultatory, he showed pulmonal stasis at both sides and a tachyarrhythmic action, with a systolic murmur 5/6 grade above the mitral valve. Echocardiography showed grave mitral regurgitation with prolapsus of posterior leaflet with suspected chordal rupture. At coronarography no significant lesions of coronary arteries were found. After hemodynamic stabilization the patient was operated. During the operation, Transesophageal echocardiography (TEE examination showed a rupture of the head of the posteromedial papillary muscle. He was surgically treated with atypical quadrantectomy of posterior leaflet with homologous pericardial patch anuloplasty. Conclusion. The recognition of acute mitral regurgitation caused by the papillary muscle rupture and prompt surgical treatment is of vital interest for the survival of patients.

A Computerized Hospital Patient Information Management System

The information processing needs of a hospital are many, with varying degrees of complexity. The prime concern in providing an integrated hospital information management system lies in the ability to process the data relating to the single entity for which every hospital functions - the patient. This paper examines the PRIMIS computer system developed to accommodate hospital needs with respect to a central patient registry, inpatients (i.e., Admission/Transfer/Discharge), and out-patients. Finally, the potential for expansion to permit the incorporation of more hospital functions within PRIMIS is examined.

Previous studies have indicated the use of medication by children to be dependent on the attitudes of knowledge of their parents; however, little is known about sources parents might use in driving medication use decisions. The aim of this study was to describe the information sources that parents use regarding their children's medication and their perceptions of the reliability of these information sources. This study is part of a cross-sectional population survey with a random sample of 6000 children younger than 12 years. The response rate of the questionnaire was 67%. Parents were asked about the use of information sources and their perception of reliability with a list of 16 information sources. The information sources that parents reported having used were physicians (72%), patient information leaflets (PILs) (67%), public or school health nurses (52%), and pharmacists (44%). Regardless of the child's age, physicians were the parents' most-used information source. Physicians were the most-used information source also when the child had at least 1 of the 4 most common long-term diseases among children in Finland (asthma, diabetes, epilepsy, and juvenile idiopathic arthritis). Parents considered physicians (50%), PILs (31%), pharmacists (27%), nurses (20%), and public or school health nurses (17%) very reliable information sources. Finnish parents seek information from health care professionals and PILs when looking for information concerning their children's medication. Furthermore, they find health care professionals and PILs to be reliable information sources. Copyright © 2012 Elsevier Inc. All rights reserved.

A novel Virtual Organization framework which incorporates wireless technology support is presented in the research work. The Virtual Organization is designed for a clinical environment to provide better patient information management and enhanced collaborative working of multidisciplinary care teams. The analysis studies the current clinical practices and looks at the general patient information resource structure currently in use for patient care. Based on this problem analysis and current requirements of the multi-disciplinary care team members, we propose a generic and sustainable Patient Centric Virtual Organization (PCVO) framework to complement the functionality of the existing infrastructure by incorporating wireless technologies support for improved patient information provision at the point of care. The preliminary results of the study identify and classify the specific point of care tasks suited to appropriate information resources needed by the care team members. This paper concentrates on the patient information management aspects brought in by incorporating wireless technologies at the point of care using patient information resources in a decentralized and distributed computing environment. This applied research is carried out in the secondary and tertiary care sector in the cancer domain. For the analysis and results of the pilot project, we have used a case study of a local NHS Cancer Hospital.

To identify the variables affecting patients' online health information-seeking behaviours by examining the relationships between patient participation in their healthcare and online health information-seeking behaviours. A cross-sectional survey of Italian chronic patients (N=352) was conducted on patient's online health information-seeking behaviours and patient participation-related variables. Structural equation modeling analysis was conducted to test the hypothesis. This study showed how the healthcare professionals' ability to support chronic patients' autonomy affect patients' participation in their healthcare and patient's online health information-seeking behaviours. However, results do not confirm that the frequency of patients' online health-information seeking behavior has an impact on their adherence to medical prescriptions. Assuming a psychosocial perspective, we have discussed how patients' engagement - conceived as the level of their emotional elaboration of the health condition - affects the patients' ability to search for and manage online health information. To improve the effectiveness of patients' online health information-seeking behaviours and to enhance the effectiveness of technological interventions in this field, healthcare providers should target assessing and improving patient engagement and patient empowerment in their healthcare. It is important that health professionals acknowledge patients' online health information-seeking behaviours that they discuss the information offered by patients and guide them to reliable and accurate web sources.

We report on a male patient suffering from loss of weight, fatigue, fever, eosinophilia, and hyperthyreoidism. The echocardiogram revealed a left atrial mass originating from the posterior mitral leaflet. In combination with the constitutional symptoms a left atrial myxoma was diagnosed. The tumor was surgically removed. Postoperatively therapy with corticosteroids and thiamazole was stopped. During follow-up, eosinophilia and hyperthyreodism could no longer be detected.

Morphologic-echocardiographic correlates of Ebstein's malformation.

Rusconi, P G; Zuberbuhler, J R; Anderson, R H; Rigby, M L

1991-07-01

The cross-sectional echocardiographic findings were analysed retrospectively in 26 patients with Ebstein's malformation in the light of studies of autopsied specimens from different patients showing this lesion. The salient anatomical feature in diagnosis is the finding of the hinge point of the septal and mural leaflets of the valve within the inlet component of the right ventricle rather than at the atrioventricular junction. The other important feature is the nature of the distal attachment of the leaflets, particularly the anterosuperior one, which can either be in focal or linear fashion. The hinge point of the septal leaflet was noted echocardiographically to be displaced in 19 patients but, significantly, the leaflet was absent in the other seven. Also significant was that the hinge point of the mural leaflet at the crux had been visualized in only 15 of the patients. The anterosuperior leaflet had a distal linear attachment in 20 of the patients, with the anteroseptal commissure becoming a keyhole in six of these through which blood passed to the functional right ventricle. The valve remained a competent structure, even though closing at the junction of atrialized and functional components of the right ventricle rather than at the atrioventricular junction. Cross-sectional echocardiography is the technique of choice with which to display the salient morphological features of Ebstein's malformation.

The process by which patients are informed and their consent is obtained in phase I trials has thus far been only marginally studied. Since 1986 we have followed an oral procedure, consisting of three consecutive conversations in which the investigator responsible for phase I studies, the research nurse and the patients' relatives and/or friends also participate, followed by the patients signing of a written consent form. It is required that six items of information considered essential by our staff be conveyed to patients by the responsible investigator. Meerwein's model, which defines three main dimensions of the informing process (the information itself, the emotional and interactive aspects), has been studied to ascertain whether it can be applied to evaluate the quality of the information proffered. Thirty-two conversations were taped, transcribed and evaluated by one psychiatrist and one psychologist. A quantitative analysis of information was performed by calculating the number of patients to whom the essential items of information had been conveyed. The qualitative analysis was performed by rating on a five-point scoring system, from 1 (very bad) to 5 (excellent), the three dimensions of the informing process for each patient and by calculating for each dimension the mean score of the constituent items. Complete information about the characteristics of the phase I drug and the modalities of the treatment and follow up was given to almost 80% of the patients. All but one of the items of the information dimension scored 3.5 or higher, with the one related to the assessment by the doctor of the patient's understanding at the end of the consultation scoring less than 3 in 53% of the patients. All items of the emotional dimension scored higher than 3.5. Greater difficulty was encountered by the physician with the interactive dimension, the lowest mean scores being reported on the items related to the doctor's awareness of the indirectly expressed anxieties of

To discover missed opportunities for providing information to women undergoing breast reconstruction in an effort to decrease regret and improve patient education, teaching modalities, and satisfaction. Thirty- to 45-minute semi-structured interviews were conducted exploring patient experiences with information provision on breast reconstruction. Purposeful sampling was used to include women with a variety of reconstruction types at different time points along their recovery. Using grounded theory methodology, 2 independent reviewers analyzed the transcripts and generated thematic codes based on patient responses. BREAST-Q scores were also collected to compare satisfaction scores with qualitative responses. Patients were interested in a wide variety of topics related to breast reconstruction including the pros and cons of different options, nipple-sparing mastectomies, immediate breast reconstruction, oncological safety/monitoring and the impact of chemotherapy and radiotherapy, secondary procedures (balancing, nipple reconstruction), post-operative recovery, and long-term expectations. Patients valued accessing information from multiple sources, seeing numerous photographs, being guided to reliable information online, and having access to a frequently asked questions file or document. Information delivery via interaction with medical personnel and previously reconstructed patients was most appreciated. Compared with BREAST-Q scores for satisfaction with the plastic surgeon (mean: 95.7, range: 60-100), informational satisfaction scores were lower at 74.7 (50-100), confirming the informational gaps expressed by interviewees. Women having recently undergone breast reconstruction reported key deficiencies in information provided prior to surgery and identified preferred information delivery options. Addressing women's educational needs is important to achieve appropriate expectations and improve satisfaction.

The information needs of cancer patients are highly variable. Literature suggests an improved ability to modulate personalised stress, increased patient involvement with decision making, greater satisfaction with treatment choices and reduced anxiety levels in cancer patients who have access to information. The aim of this project was to evaluate the effects of a mobile information application on anxiety levels of patients undergoing surgery for breast cancer. An application was developed for use with Apple iPad containing information on basic breast cancer biology, different treatments used and surgical techniques. Content and face validity studies were performed. A randomized control trial was designed, with a 1:2 allocation. Data collected include basic demographics and type of surgery. Questionnaires used included: the HADS, Mini-MAC, information technology familiarity and information satisfaction. A total of 39 women participated. 13 women had access to an iPad containing additional information and 26 women acted as controls. The mean age was 54 and technology familiarity was similar among both groups. Anxiety and depression scores at seven days were significantly lower in control patients without access to the additional information provided by the mobile application (p = 0.022 and 0.029 respectively). Anxiety and depression in breast cancer patients is both multifactorial and significant, with anxiety levels directly correlating with reduced quality of life. Intuitively, information should improve anxiety levels, however, we have demonstrated that surgical patients with less information reported significantly lower anxiety. We advise the thorough testing and auditing of information initiatives before deployment. Copyright © 2016 Elsevier Ltd. All rights reserved.

The aims of the present study were to identify information that individuals with whiplash associated disorders (WAD) need to know in the early stages of recovery and to establish whether there is a difference between what physiotherapists and whiplash-injured patients perceive as important information. Forty-one participants were recruited (20 whiplash-injured patients, 21 physiotherapists). Participants were asked to provide five statements to one open-ended question about what they believe is the most important information individuals with WAD need to know in the early stages of recovery. Participants provided 182 statements which were reviewed independently and organised into themes by two of the authors. Six key themes emerged from the statements. These included general information about whiplash injury, treatment and recovery, reassurance, provision of poor information and patients' interaction with general practitioners, maintaining daily activities, and compensation claims and litigation. Both patients and physiotherapists agreed on the type of general whiplash information that should be provided however, major differences were found with regard to information pertaining to compensation claims and litigation and maintaining daily activities. The findings of this study provide some insight into the type of information that WAD individuals require in the early stages of recovery. Implications for Rehabilitation The provision of reassurance can be an effective communication tool to decrease patients concerns about their injury and help strengthen the patient-health practitioner relationship. Although clinical guidelines for the management of whiplash injuries recommend that individuals must remain physically active post-injury, statements from the patient group indicate that this information is not always provided and clearly explained to patients. Keeping in line with the patient centred care approach of being responsive to patient needs and values, it is

The impact of health information technology on patient safety.

Alotaibi, Yasser K; Federico, Frank

2017-12-01

Since the original Institute of Medicine (IOM) report was published there has been an accelerated development and adoption of health information technology with varying degrees of evidence about the impact of health information technology on patient safety.  This article is intended to review the current available scientific evidence on the impact of different health information technologies on improving patient safety outcomes. We conclude that health information technology improves patient's safety by reducing medication errors, reducing adverse drug reactions, and improving compliance to practice guidelines. There should be no doubt that health information technology is an important tool for improving healthcare quality and safety. Healthcare organizations need to be selective in which technology to invest in, as literature shows that some technologies have limited evidence in improving patient safety outcomes.

The Norwegian Electronic Health Library (The Library) is a website for health personnel. Most of the content is also open to the public. Usage statistics have risen sharply in the years 2010-2013. We wanted to find out whether the rise was caused by health personnel, the general public, or other factors. Since we lacked direct information, we had to use proxy data to shed light on our questions. We applied mixed methods (database of registered users, user survey, usage statistics, and statistics from suppliers), and triangulated between them. Health personnel were our largest user group, but The Library was also accessed by students, patients, and other groups. Content in Norwegian was preferred to English language content. Concise, practical information was preferred to more comprehensive information. Patient leaflets were the most popular information type. Mobile phone visits differed from personal computer visits both in terms of time of day and what kind of information was viewed. The Library was used mostly by health personnel, as intended, but our data are inconclusive regarding a possible change in user groups. There was a large degree of consistency in results when using different investigation methods. The survey points toward health personnel being the largest user group, and the usage statistics show that patient leaflets are the most popular content, being viewed by both health personnel and patients.

Patient-prosthesis mismatch (PPM) should be recognized in patients with elevated transprosthetic gradients but without leaflet immobility, since the treatment strategy may differ in either etiology. However, thrombus and/or pannus formation should be excluded before a diagnosis of PPM is made. Particularly, pannus formation may not be diagnosed with 2-dimensional transesophageal echocardiography. Electrocardiographically gated 64-section multidetector computed tomography (MDCT) may be a promising tool in diagnosing or excluding pannus formation. Our report underlines the utility of MDCT in this regard and also emphasizes the importance of recognition of PPM as a differential diagnosis in such patients.

Are anticoagulant independent mechanical valves within reach-fast prototype fabrication and in vitro testing of innovative bi-leaflet valve models.

Exploration for causes of prosthetic valve thrombogenicity has frequently focused on forward or post-closure flow detail. In prior laboratory studies, we uncovered high amplitude flow velocities of short duration close to valve closure implying potential for substantial shear stress with subsequent initiation of blood coagulation pathways. This may be relevant to widely accepted clinical disparity between mechanical and tissue valves vis-à-vis thrombogenicity. With a series of prototype bi-leaflet mechanical valves, we attempt reduction of closure related velocities with the objective of identifying a prototype valve with thrombogenic potential similar to our tissue valve control. This iterative design approach may find application in preclinical assessment of valves for anticoagulation independence. Tested valves included: prototype mechanical bi-leaflet BVs (n=56), controls (n=2) and patented early prototype mechanicals (n=2) from other investigators. Pulsatile and quasi-steady flow systems were used for testing. Projected dynamic valve area (PDVA) was measured using previously described novel technology. Flow velocity over the open and closing periods was determined by volumetric flow rate/PDVA. For the closed valve interval, use was made of data obtained from quasi-steady back pressure/flow tests. Performance was ranked by a proposed thrombogenicity potential index (TPI) relative to tissue and mechanical control valves. Optimization of the prototype valve designs lead to a 3-D printed model (BV3D). For the mitral/aortic site, BV3D has lower TPI (1.10/1.47) relative to the control mechanical valve (3.44/3.93) and similar to the control tissue valve (ideal TPI ≤1.0). Using unique technology, rapid prototyping and thrombogenicity ranking, optimization of experimental valves for reduced thrombogenic potential was expedited and simplified. Innovative mechanical valve configurations were identified that merit consideration for further development which may bring

The provision of information is now considered a major area in pharmacist-patient interactions. However, few reports have simultaneously evaluated patient and pharmacist perceptions with regard to the pharmacist's information provision. The aims were to clarify the perceptions of pharmacists and patients regarding information provision and the level of influence of those perceptions on patient satisfaction. A cross-sectional survey with respect to information provision was conducted for patients and pharmacists in community pharmacies in Fukuoka Prefecture, Japan. In total, 407 patient-pharmacist pairs were included in a t-test and multilevel analysis. The levels of patient perception regarding information provision were significantly higher than the levels of pharmacist perception in all variables. The pharmacists' perceived level of information provision concerning medication effects had a negative and significant association with patient satisfaction, while the patients' perceived level of information provision by the pharmacist had a positive and significant association with patient satisfaction. Higher patient expectations regarding the level of information provision concerning medication side effects and older age of the pharmacist were adversely related to patient satisfaction. Both pharmacist and patient perceptions of the information provision by pharmacists personalized to the patient had positive associations with patient satisfaction. Pharmacist perceptions related to the information provision were not associated with patient satisfaction. The present study highlights accurate information provision, building good patient-pharmacist relationships, and improving pharmaceutical care in community pharmacy settings. © 2015 John Wiley & Sons, Ltd.

We report a rare case of a prosthetic aortic valve obstruction due to pannus formation only 3 months following aortic and mitral valve replacement. Fragments of asymmetrical pannus formation affected one of the leaflets of the bi-leaflet mechanical valve; the leaflet appeared immobile due to pannus ingrowth into the mechanical skeleton resulting in encroachment of the leaflet, which in turn became immobile. The patient successfully underwent emergency redo-aortic valve replacement.

The decision to participate or not in breast cancer screening is complex due to the trade-off between the expected benefit of breast cancer mortality reduction and the major harm of overdiagnosis. It seems ethically necessary to inform women so that they can actively participate in decision-making and make an informed choice based on their values and preferences. The objective of this study is to assess the effects of receiving information about the benefits and harms of screening on decision-making, in women approaching the age of invitation to mammography screening. A two-stage, randomized controlled trial (RCT). In the first stage, 40 Basic Health Areas (BHAs) will be selected and randomized to intervention or control. In the second stage, women within each BHA will be randomly selected (n = 400). Four breast cancer screening programs (BCSPs) of the Spanish public health system, three in Catalonia and one in the Canary Islands will participate in the study. Women in the intervention arm will receive a leaflet with detailed information on the benefits and harms of screening using mammography. Women in the control arm will receive a standard leaflet that does not mention harms and recommends accepting the invitation to participate in the biennial examinations of the BCSP. The primary outcome is informed choice, a dichotomous variable that combines knowledge, attitudes, and intentions. Secondary outcomes include decisional conflict; confidence in the decision made; anxiety about screening participation; worry about breast cancer; anticipated regret; time perspective; perceived importance of benefits/harms of screening; perceived risk of breast cancer; and leaflet acceptability. Primary and secondary outcomes are assessed 2-3 weeks after the intervention. This is the first RCT that assesses the effect of informing about the benefits and harms of breast cancer screening in Spain in women facing the decision to be screened using mammography. It aims to assess the

1. To describe the information provided to, or inquired about, by patients with axial spondyloarthritis and psoriatic arthritis. 2. To analyze improvements. Analysis of the discourse of focus groups (with patients, some of them from patient associations, and rheumatologists). The discussion included the identification of elements that shape the reality being studied, describing the relationship among them and summarizing the results by: 1)thematic segmentation; 2)categorization according to situations, relationships, opinions, feelings or others; 3)coding of the various categories, and 4)interpretation of results. Representativeness was ensured by using a typological framework. Rheumatologists are the main source of information. Patient associations have a fundamental role and are well-regarded. Internet is used with caution due to its limited reliability. Patients are interested in: disease characteristics and treatments, the course and prognosis, and social, administrative and other kinds of support. More information is needed (objective and constructive, avoiding a catastrophic tone); it should be provided progressively, adjusted to patients features and needs. There are areas for improvement including: the standardization and updating of contents (based on scientific evidence), the optimization of informative materials (written, electronic), and other resources such as nursing and primary care. Rheumatologists are the main and most reliable source of information for patients with spondyloarthritis and psoriatic arthritis. Patient associations have an important role and are well-regarded. Changes in the content, format and sources of information are required. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Full Text Available Abstract Background Injuries in or around the home are the most important cause of death among children aged 0-4 years old. It is also a major source of morbidity and loss of quality of life. In order to reduce the number of injuries, the Consumer Safety Institute introduced the use of Safety Information Leaflets in the Netherlands to provide safety education to parents of children aged 0-4 years. Despite current safety education, necessary safety behaviours are still not taken by a large number of parents, causing unnecessary risk of injury among young children. In an earlier study an E-health module with internet-based, tailored safety information was developed and applied. It concerns an advice for parents on safety behaviours in their homes regarding their child. The aim of this study is to evaluate the effect of this safety information combined with personal counselling on parents' child safety behaviours. Methods/Design Parents who are eligible for the regular well-child visit with their child at child age 5-8 months are invited to participate in this study. Participating parents are randomized into one of two groups: 1 internet-based, tailored safety information combined with personal counselling (intervention group, or 2 personal counselling using the Safety Information Leaflets of the Consumer Safety Institute in the Netherlands for children aged 12 to 24 months (control group. All parents receive safety information on safety topics regarding the prevention of falling, poisoning, drowning and burning. Parents of the intervention group will access the internet-based, tailored safety information module when their child is approximately 10 months old. After completion of the assessment questions, the program compiles a tailored safety advice. The parents are asked to devise and inscribe a personal implementation intention. During the next well-child visit, the Child Health Clinic professional will discuss this tailored safety information

The French Radiotherapy-Oncology Society (SFRO) and the National Trade of Radiotherapists-Oncologists (SNRO) elaborated and published a patient information booklet on radiotherapy, in 1999. This present study appraises the pertinence of the form and substance of this booklet one year after its release. Eight radiotherapy centers participated in this research which evaluated 162 patients at treatment initiation. The conclusions of this study demonstrated the importance of clearly informing patients of their disease, treatment, and the secondary effects of treatment. It is essential to emphasize that 97% of the patients declared that an information booklet is a real necessity, and that the one provided by the SFRO responds to the majority of their concerns. Obtaining technical and practical knowledge resulted in a reassurance about their treatment. The most revealing result is that 87% requested direct communication about their illness, and that cancer be named by this word and not other, evasive terms. Seventy-two percent of the patients requested more information about their cancer, different treatment options, and quality of life issues in an attempt to psychologically prepare themselves to face an illness for which they have little control. Patients refuse to be passive, and claim the right to become 'partners' of the medical teams, concerning their treatment and recovery. (authors)

Little is known about the information sources of Chinese patients with cancer and their family caregivers, yet this knowledge is critical for providing patient-centred care. To assess and compare the information sources used by Chinese patients with cancer and their family caregivers. The validated Health Information Wants Questionnaire (HIWQ) was translated and administered in March 2014. The oncology department of a general hospital in south-west China. A convenience sample of 198 individuals, including 79 patients with cancer (mean age=55.24, SD=13.80) and 119 family caregivers (mean age=46.83, SD=14.61). Ratings on the HIWQ items assessing information sources for different types of information. The interaction between information source and group was significant (F 3,576 =6.32, Pinformation than patients from the Internet. Caregivers and patients did not differ in the amount of information they obtained from doctors/nurses, interpersonal contacts or mass media. The interaction between information type and information source was significant (F 18,3456 =6.38, Pinformation of all types from doctors/nurses than from the other three sources and obtained more information from interpersonal contacts than from mass media or the Internet. The information sources of Chinese patients with cancer and their family caregivers were similar, with an important difference that caregivers obtained more online information than patients. These findings have important implications for patient care and education in China where the family typically plays a major role in the care and decision making. © 2016 The Authors.

The side effects of antiretroviral (ARV) therapy are linked to altered quality of life and adherence. Poor adherence has also been associated with low health-literacy skills, with an uninformed patient more likely to make ARV-related decisions that compromise the efficacy of the treatment. Low literacy skills disempower patients in interactions with healthcare providers and preclude the use of existing written patient information materials, which are generally written at a high reading level. Visual images or pictograms used as a counselling tool or included in patient information leaflets have been shown to improve patients' knowledge, particularly in low-literate groups. The objective of this study was to design visuals or pictograms illustrating various ARV side effects and to evaluate them in a low-literate South African Xhosa population. Core images were generated either from a design workshop or from posed photos or images from textbooks. The research team worked closely with a graphic artist. Initial versions of the images were discussed and assessed in group discussions, and then modified and eventually evaluated quantitatively in individual interviews with 40 participants who each had a maximum of 10 years of schooling. The familiarity of the human body, its facial expressions, postures and actions contextualised the information and contributed to the participants' understanding. Visuals that were simple, had a clear central focus and reflected familiar body experiences (e.g. vomiting) were highly successful. The introduction of abstract elements (e.g. fever) and metaphorical images (e.g. nightmares) presented problems for interpretation, particularly to those with the lowest educational levels. We recommend that such visual images should be designed in collaboration with the target population and a graphic artist, taking cognisance of the audience's literacy skills and culture, and should employ a multistage iterative process of modification and

Two-dimensional echocardiographic findings in porcine valve dysfunction were compared with pathologic findings in 10 patients (12 valves). Three specific echocardiographic findings were identified in patients with regurgitant lesions: prolapse, fracture and flail leaflets. Prolapse was associated pathologically with thinning of the leaflets, longitudinal tears close to the ring margin and acid mucopolysaccharide accumulation. Valve fracture was seen with and without prolapse and was accompanied pathologically by small pinpoint perforations or tears of the leaflet. A flail leaflet was seen with a linear tear of the free margin and was associated with calcific deposits. Mild degrees of fracture seen pathologically were missed on the echocardiographic study in five patients. Thickening or calcification, when present in moderate or severe amounts, was correctly identified by echocardiography. When all abnormal features were considered collectively, two-dimensional echocardiography correctly identified at least one of them in all patients. Therefore, two-dimensional echocardiography may prove useful in assessing the source of valvular regurgitation in patients with bioprosthetic valves.

To provide insight into the perceived need for information of patients with haematological malignancies. Providing timely and accurate information to patients diagnosed with a haematological malignancy is a challenge in clinical practice; treatment often has to start promptly, with little time to inform patients. Literature review. A comprehensive literature search was conducted from all available literature to May 2013 in the databases: Cumulative Index to Nursing and Allied Health Literature, PsycINFO and PubMed (Medline). Relevant studies were reviewed regarding the perceived need for information on various topics, sources of information and satisfaction with information provided. The initial search revealed 215 articles, fourteen of which were relevant. Patients need basic information on the disease (diagnosis and diagnostics), treatment (various treatment options, side effects and duration), prognosis (curability and prolonging life) and all other topics (recovery, self-care and psychosocial functioning). Need for detailed information varied between studies. Patients expressed a higher need for medical than for psychosocial information. Patients preferred to receive information from their doctors the most, followed by nurses. Most studies described patients' satisfaction with the information provided. Based on the limited number of data available, medical information is for patients of higher priority compared to psychosocial information. Patients need basic information on diagnosis, treatment, prognosis and all other topics. Need for detailed information varied between studies. Patients were satisfied with the provided information, preferably offered by doctors and nurses. The perceived need for information and satisfaction with the information provided differs strongly between patients. In clinical practice, more attention is needed for information tailored to the patient, taking into account important moderating factors such as age, type of cancer, time

In discussions on the quality of cross-sectorial health-care services high importance is attributed to patient education and patient counseling, with guideline-based patient information being considered a crucial tool. Guideline-based patient information is supposed to serve patients as a decision-making basis and, in addition, to also support the implementation of the guidelines themselves. The article highlights how patient guidelines for National Disease Management Guidelines in Germany--within the scope of patient education and patient counseling--may provide a uniform information platform for physicians and patients aiming to promote shared decision-making. The authors will also address the issue which contents should be included in patient guidelines in order to meet these requirements and which measures are required to review their quality. The present paper continues the series of articles on the Program for German National Disease Management Guidelines.

1997-01-01

Background and purpose: We performed a survey to evaluate the present status and means of information given to patients treated by radiotherapy. A short questionnaire was sent, with the help of ESTRO, to 746 European heads of department with a request to send specific documents used for informing the patient. Within 2 months (March and April 1996) we received 290 answers (39%) and 97 centres sent documents. Materials and methods: Analysis of the questionnaire and the documents was performed quantitatively with usual statistical methods and qualitatively with a socio-anthropological method of content analysis. Results: Analysis of the questionnaire shows the major role of the radiation oncologist in giving information and writing documents. The 298 different samples sent from 97 centres represent a wide panel with a booklet of general information (59 booklets/57 centres), practical advice and specific explanations (177 documents/49 centres) and informed consent (36 documents/28 centres). The anthropological study was centred on the way information was given, evaluation of the patient's understanding and analysis of documents sent. Conclusion: This preliminary survey needs to be completed by a study, including the patient's point of view and needs, about the information given

According to the recent worldwide estimation by the GLOBOCAN project, in total, 12.7 million new cancer cases and 7.6 million cancer deaths occurred in 2008. The worldwide number of cancer survivors within 5 years of diagnosis has been estimated at be almost 28.8 million. Informal caregivers, such as family members and close friends, provide essential support to cancer patients. The authors of this report provide an overview of issues in the study of informal caregivers for cancer patients and long-term survivors in the United States and Europe, characterizing the caregivers commonly studied; the resources currently available to them; and their unmet needs, their psychosocial outcomes, and the psychosocial interventions tailored to their special circumstances. A broad overview of the state of research and knowledge, both in Europe and the United States, and observations on the directions for future research are provided. PMID:23695928

2009-09-01

Full Text Available Abstract Background Information transfer is critical in the primary care to specialist referral process and has been examined extensively in the US and other countries, yet there has been little attention to the patient's perspective of the information transfer process. This cross-sectional study examined the quality of the information received by patients with a chronic condition from the referring and specialist physician in the specialist referral process and the relationship of the quality of information received to trust in the physicians. Methods Structured telephone interviews were conducted with a random sample of 250 patients who had experienced a referral to a specialist for the first visit for a chronic condition within the prior six months. The sample was selected from the patients who visited specialist physicians at any of the 500 hospitals from the National Research Corporation client base. Results Most patients (85% received a good explanation about the reason for the specialist visit from the referring physician yet 26% felt unprepared about what to expect. Trust in the referring physician was highly associated with the preparatory information patients received. Specialists gave good explanations about diagnosis and treatment, but 26% of patients got no information about follow-up. Trust in the specialist correlated highly with good explanations of diagnosis, treatment, and self-management. Conclusion Preparatory information from referring physicians influences the quality of the referral process, the subsequent coordination of care, and trust in the physician. Changes in the health care system can improve the information transfer process and improve coordination of care for patients.

This paper is a report of a study to describe nurses' experiences of information technology-based standardized patient education in inpatient psychiatric care. Serious mental health problems are an increasing global concern. Emerging evidence supports the implementation of practices that are conducive to patient self-management and improved patient outcomes among chronically ill patients with mental health problems. In contrast, the attitude of staff towards information technology has been reported to be contradictory in mental health care. After 1 year of using an Internet-based portal (Mieli.Net) developed for patients with schizophrenia spectrum psychosis, all 89 participating nurses were asked to complete questionnaires about their experiences. The data were collected in 2006. Fifty-six participants (63%) returned completed questionnaires and the data were analysed using content analysis. Nurses' experiences of the information technology-based standardized patient education were categorized into two major categories describing the advantages and obstacles in using information technology. Nurses thought that it brought the patients and nurses closer to each other and helped nurses to provide individual support for their patients. However, the education was time-consuming. Systematic patient education using information technology is a promising method of patient-centred care which supports nurses in their daily work. However, it must fit in with clinical activities, and nurses need some guidance in understanding its benefits. The study data can be used in policy-making when developing methods to improve the transparency of information provision in psychiatric nursing.

Information security requirements in patient-centred healthcare support systems.

Enabling Patient-Centred (PC) care in modern healthcare requires the flow of medical information with the patient between different healthcare providers as they follow the patient's treatment plan. However, PC care threatens the stability of the balance of information security in the support systems since legacy systems fall short of attaining a security balance when sharing their information due to compromises made between its availability, integrity, and confidentiality. Results show that the main reason for this is that information security implementation in discrete legacy systems focused mainly on information confidentiality and integrity leaving availability a challenge in collaboration. Through an empirical study using domain analysis, observations, and interviews, this paper identifies a need for six information security requirements in legacy systems to cope with this situation in order to attain the security balance in systems supporting PC care implementation in modern healthcare.

Full Text Available Full training according to the information needs of patients reduces health care costs and increases the quality of care. The present study was conducted aims to prioritize the preferences of hemodialysis patients in acquisition of health information to be able to provide training according to these preferences and their prioritization after achieving them. This study was a descriptive cross-sectional one which was conducted on all hemodialysis patients who visited Kowsar Hospital in Semnan within the year 2014-2015. Data collecting tool was researcher-made questionnaire which assessed physical information needs of patients in four areas of nutrition, energy, pain and discomfort, sleep and rest. Data were analyzed by SPSS software version 16 using the descriptive statistics.71 hemodialysis patients participated in this study. 68.6%, 50.7%, 42.6% and 46.7% of patients expressed acquisition information regarding hematopoietic foods, how to increase mobility, how to relieve itching during dialysis and mental activities before sleep as their first priorities, respectively. The results of this study showed that hemodialysis patients need to know what kinds of information in the field of physical problems. To facilitate adaptation and selfcare of patients, providing information and training based on the real needs of patients will be helpful.

Remembering medical treatment information may be particularly taxing for older cancer patients, but to our knowledge this ability has never been assessed in this specific age group only. Our purpose in this study was to investigate older cancer patients' recall of information after patient education preceding chemotherapy. We constructed a recall questionnaire consisting of multiple-choice questions, completion items, and open-ended questions related to information about treatment and recommendations on how to handle side effects. Immediately after a nursing consultation preceding chemotherapy treatment, 69 older patients (M = 71.8 years, SD = 4.1) completed the questionnaire. We checked recall against the actual communication in video recordings of the consultations. On average, 82.2 items were discussed during the consultations. The mean percentage of information recalled correctly was 23.2% for open-ended questions, 68.0% for completion items, and 80.2% for multiple-choice questions. Older cancer patients are confronted with a lot of information. Recall of information strongly depended on question format; especially active reproduction appeared to be poor. To improve treatment outcomes, it is important that cancer patients are able to actively retrieve knowledge about how to prevent and recognize adverse side effects and that this is checked by the health professional. We make suggestions on how to make information more memorable for older cancer patients.

Although much health information-seeking behaviour (HISB) research has been reported in patients with good literacy skills, little is known about HISB in patients with limited literacy skills served by under-resourced health-care systems. To investigate medicine information-seeking behaviour and information needs in patients with limited literacy. Using a question guide, four focus group discussions (FGDs) were conducted to explore themes related to information needs, information-seeking practices and awareness of and ability to utilize information sources. Twenty-two isiXhosa-speaking long-term patients with limited formal education were recruited from a primary health-care clinic in South Africa. Discussions were audio-recorded and transcribed verbatim. NVivo(®) was used for initial coding of transcripts. Codes were analysed, and potential themes and subthemes in the entire data set were identified and refined. The results of this study reflect a passive, disempowered patient. Poor awareness of information sources, lack of health-related knowledge and stigma contributed to a lack of information-seeking practice, thus potentially adversely influencing patient-provider interactions. Patients neither asked questions nor were encouraged to ask questions. All expressed an unmet need for information and a desire for receiving the illustrated written medicines-related information displayed in the FGDs. The main sources of information were health-care professionals, followed by family and friends. The significant level of patient disempowerment and passivity reported amongst patients underpinned their inability to actively seek information. Neither sources of information nor types of appropriate medicines information could be identified. Unmet information needs and a desire for information were reported. © 2013 John Wiley & Sons Ltd.

The impact of health information technology on patient safety

2017-12-01

Full Text Available Since the original Institute of Medicine (IOM report was published there has been an accelerated development and adoption of health information technology with varying degrees of evidence about the impact of health information technology on patient safety. This article is intended to review the current available scientific evidence on the impact of different health information technologies on improving patient safety outcomes. We conclude that health information technology improves patient’s safety by reducing medication errors, reducing adverse drug reactions, and improving compliance to practice guidelines. There should be no doubt that health information technology is an important tool for improving healthcare quality and safety. Healthcare organizations need to be selective in which technology to invest in, as literature shows that some technologies have limited evidence in improving patient safety outcomes.

Patients with depression are often dissatisfied with disease- and therapy-related information. The objective of this study was to evaluate an intervention that applied the Common Sense Model to the provision of information during inpatient rehabilitation for patients with depression. The intervention was evaluated in a sequential control group design. Analyses of covariance were used to assess differences between the control and intervention groups. Changes with respect to illness and treatment beliefs (personal control, treatment control, coherence and concerns about medicines), satisfaction with information about medicines, illness and rehabilitation, and depressive burden were selected as primary outcome measures. We observed significant between-group differences indicating the intervention group's superiority in terms of satisfaction with information regarding medicines. However, the two groups' changes during rehabilitation did not differ in terms of the other outcomes. The intervention resulted in patients judging that their medication information needs had been more thoroughly fulfilled than those patients who received care-as-usual information. However, the intervention did not prove to be effective when the other outcome variables are considered. Taken together and bearing in mind the limitations of our study-particularly the non-randomised design-our results should be replicated in a randomised controlled trial.

Imparting bad news had always been an unpleasant task for the physician, as shown from ancient years to our days. In the healthcare sector and as far as the cancer patient is concerned, the imparting of bad news is performed by the patient's doctor within a therapeutic relationship of course. The fundamental question is how a therapist could tailor the information to any patient and if "Is it possible to determine who should be told what, when and how ?". The aim of this paper was to describe the suspicious character or type of personality thoroughly so that any physician can make a diagnosis and tailor the information strategy to the patient's needs. As method of research was used the qualitative method through groups with doctors and nurses, while research within groups lasted for 5 years. The degree of informing of the suspicious personality in the range "minimal - small - medium - large - very large" is : the degree of denial varies between large and very large. The degree of informing varies between medium and small and sometimes minimal. Informing the Family: The hardest family to deal with. Pay attention to litigious mania. Avoid confrontation or be drawn into agreeing with the family views.

Full Text Available BACKGROUND: In Europe, new cases of cancer are diagnosed in 4 million people yearly, of whom 837 000 die. In Ukraine of 160 000 new cases almost 100 000 die. With proper treatment, one third of cancer cases is curable, but informal payments (IPP in health care limit access to treatment. We aimed to explore the experience of people treated for cancer to identify obstacles in obtaining health care and the expert opinion about health care for cancer patients in Ukraine.METHODS: The study is exploratory. Semi-structured in-depth interviews were conducted with 15 convenience sample patients or their relatives as well as with three experts between October 2011 – April 2012. RESULTS. Solicitation or receipt of IPP depends on the organizational culture. Respondents do not mind about IPP, but want this to be their own decision. IPP are often considered a “thank” to the medical staff for the service. The significant percentage of expenditures while in treatment for patients is due to purchases of medicines at their own expense. The problem of a long process of diagnostics and incomplete information by the medical staff about the stage of cancer and possible prognoses are essential for the respondents. According to experts not sufficient number of specialists and equipment for proper diagnosis and treatment is another problem. The attitude of medical staff to the patient with cancer largely depends on the personal features of the staff.CONCLUSIONS: Significant problems perceived by cancer patients are related to purchase of medicines at their own expense, structural and organizational features of hospitals, where they are staying for the treatment. Informal payments largely depend on the personal qualities of medical staff. The government must ensure fairness and equal access in getting care in oncology practice because it mainly affects the health of the nation.

Nuclear medicine procedures use radiopharmaceuticals, which produce radiation and potential adverse reactions, albeit at a low rate. It is the patient's ethical, legal, and medical right to be informed of the potential side effects of procedures applied to them. Our purpose was to determine the effect of providing information about intravenous radiopharmaceutical administration on the anxiety level of patients who request more information. This study was completed in two separate Nuclear Medicine Departments. The study included 620 (247 M, 373 F) patients who had been referred for myocardial perfusion, bone, dynamic renal, and thyroid scintigraphic examinations. The patients were divided into two groups according to whether they requested more information or not. Group 1 consisted of 388 patients who wanted to receive more information about the procedure, while Group 2 consisted of 232 patients who did not request additional information. The State-Trait Anxiety Inventory (STAI-S and STAI-T) was used to determine a patient's anxiety level. After simple information was given, state and trait anxiety levels were measured in both groups. We gave detailed information to the patients in Group 1 and then measured state anxiety again. Detailed information included an explanation of the radiopharmaceutical risk and probable side effects due to the scan procedure. There was no statistical difference between Groups 1 and 2 in STAI-T or STAI-S scores after simple information was given (p=0.741 and p=0.945, respectively). The mean value of STAI-S score was increased after the provision of detailed information and there was a statistically significant difference between after simple information STAI-S and after detailed information STAI-S (p<0.001). The STAI-S score was increased in 246 patients and decreased in 110 patients after detailed information, while there was no change in 32 patients. After detailed information, the greatest increase in STAI-S score was seen in the

Full Text Available Background Packages leaflets (PLs are essential for the safe use and efficacy of medicines. Aims To quantify the opinion of users of medicines on PLs through the application of a self-administered Likert scale, taking into consideration subjects’ sociodemographic data. Methods Participants were enrolled from two Portuguese regions: urban/littoral (Lisbon and rural/interior (Centre. 503 participants were included: 53 per cent males, 45 per cent 12 years of schooling. A questionnaire was used to collect the sociodemographic data. A Likert scale was self-administered to rate the characteristics of 12 randomized PLs (6 from prescription medicines and 6 from over-the-counter medicines (August-December 2014. An invitation was send to several institutions (e.g., municipal councils. The inclusion criteria were: agreeing, be capable of reading/writing, and be more than 17 years old. Results In the Likert scores obtained, no significant differences were found related to region, sex, marital status, age group (≥65 years and other, and employment status of participants. By contrast, significant differences were found related to education (2=42.747; p 12 years of schooling, more regular reading habits (2 or more books/year, higher income and less frequent medicines use, showed a more negative global opinion on PLs. Conclusion Sociodemographic data are important to understand users’ opinion on PLs. It seems that more educated subjects are more demanding. A lower socio-economic status positively influenced the participants’ opinion, with subjects’ poorer education being a relevant factor in this population. A higher frequency of taking medicines also positively contributed to a better opinion, probably due to a greater familiarity with PLs.

Patients want granular privacy control over health information in electronic medical records.

To assess patients' desire for granular level privacy control over which personal health information should be shared, with whom, and for what purpose; and whether these preferences vary based on sensitivity of health information. A card task for matching health information with providers, questionnaire, and interview with 30 patients whose health information is stored in an electronic medical record system. Most patients' records contained sensitive health information. No patients reported that they would prefer to share all information stored in an electronic medical record (EMR) with all potential recipients. Sharing preferences varied by type of information (EMR data element) and recipient (eg, primary care provider), and overall sharing preferences varied by participant. Patients with and without sensitive records preferred less sharing of sensitive versus less-sensitive information. Patients expressed sharing preferences consistent with a desire for granular privacy control over which health information should be shared with whom and expressed differences in sharing preferences for sensitive versus less-sensitive EMR data. The pattern of results may be used by designers to generate privacy-preserving EMR systems including interfaces for patients to express privacy and sharing preferences. To maintain the level of privacy afforded by medical records and to achieve alignment with patients' preferences, patients should have granular privacy control over information contained in their EMR.

Mitral valve prolapse (MVP) is closely related to myocardial sympathetic nerve function. This study evaluated the presence of impaired myocardial sympathetic nerve function by Iodine-123-metaiodobenzylguanidine (MIBG) scintigraphy in nine patients with MVP. For comparison, 15 healthy subjects without heart disease were investigated (control group). Single photon emission computed tomography (SPECT) and anterior planar myocardial scintigraphy were performed 15 min (initial images) and 3 hours (delayed images) after injection of MIBG (111 MBq). The location and degrees of reduced tracer uptake were evaluated. Myocardial MIBG uptake was quantified by uptake ratio of the heart (H) to upper mediastinum (M) on the anterior planar images (H/M). Percentage washout of MIBG in nine sectors of all oblique slices along the short-axis was calculated. The washout rates were higher at the inferoposterior and septal segments in patients with anterior leaflet prolapse, and at inferoposterior and lateral segments in patients with posterior leaflet prolapse. The bull's eye map showed increased washout rate in the apical and posteroseptal basal segments. There was no significant difference in the H/M ratio between MVP patients and the control group. These results indicate that MIBG can be used to evaluate localized myocardial sympathetic nerve function in MVP. (author)

Pectus is the most common congenital disorder. Awareness amongst primary care physicians and the general public is poor. NHS commissioning bodies plan to withdraw funding for this surgery because they deem a lack of sufficient evidence of benefit. The purpose of this study is to assess the effects of introducing a patient information website on referral and activity patterns and on patients reported outcomes. We produced an innovative information website, www.pectus.co.uk , accessible to the general public, providing information about pectus deformities; management options and advice about surgery. Referral patterns and number of cases where studied before and after the introduction of the website in 2010. Patients' satisfaction post-op was assessed using the Brompton's single step questionnaire (SSQ). The website had considerable traffic with 2179 hits in 2012, 4983 in 2013 and 7416 in 2014. This has led to 1421 contacts and 372 email enquiries. These emails have resulted in an increased number of patients who have been assessed and go on to have surgery. We asked 59 pectus excavatum patients who were operated from 2008 to 2014 to complete the SSQ. We received 32 replies. Eighty-four percent (16/19) of patients who visited the website and then underwent surgery, found the website useful. All patients scored satisfactorily in SSQ. Even though those who visited the website tended to be more satisfied with the surgical outcomes this did not reach statistical significance. This group of patients said that would have the operation again given the option compared to 76.9 % of the group who did not visit the website before surgery (p=0.031). Despite the fact that patients who visited the website experienced more post-operative complications were equally or more satisfied with post-operative outcomes. The overall SSQ obtainable score was not different for the two subgroups, being more widespread in the group that did not visit the website. The introduction of a pectus

Around one million couples in Poland suffer from infertility People in reproductive age are most active Internet users. The aim of the study was to assess Internet habits of infertile patients. We checked to what extent infertile patients seek information about infertility on-line and what is their approach to the information found. 85 female patients treated for infertility for at least one year were surveyed. The anonymous questionnaire was designed by the authors of the publication. It consisted of questions related to medical history of the patients and sources of information about infertility they used. It also checked Internet activity of the patients and contained Beck's Depression Inventory (BDI). Chi-square test and Spearman's correlation test were used to evaluate the results. The majority of patients used Internet to find information about infertility (93%); 46% of the respondent declared Internet forums to be their main source of information about it. Patients used on-line sources of information more often than stricte medical sources. Internet influenced their relation with the physician. 64% of patients verified on-line information and treatment proposed by their doctor before using them. One third of the surveyed women claimed their knowledge about infertility comes more from the Internet than the specialist who treated them. There was a positive correlation between patients who checked diagnostic or therapeutic methods proposed by their physician with depression in BDI. Considering the great impact of Internet forums and web pages on patient approach to diagnostics and treatment of infertility there seems to be a need to create a professional Polish website and forum to provide the patients with reliable information about the disease.

Training and information in the radiation protection subject is a legal mandatory as well as an essential tool for the optimisation and quality of the procedures. Accounting for the relevance of the dose to the population due to medical exposures, it seems obvious the necessity of improving this subject in order to design a feasible and efficient strategy. The importance of learning to communicate and to manage on the one hand an excessive perception of the risk to low doses in comparison with other agents, that could be made extensible for judges, lawyers and media, and on the other hand, the relevant doses due to interventional procedures, to TC studies, etc, is one of the basic commitment of a Radiation Protection Service. This paper summarises: - The contents of international recommendations, the European Directives and Spanish legislation related to this topic. - The strategy of training and information to the levels indicated, from the point of view of a referential Radiation Protection Service for a Teaching Hospital and its area associated os specialized attention and primary attention. We can not forget on-going training for owner workers. - The contents of the informative leaflets. (Author) 13 refs

Full Text Available Abstract Background The profound changes in medical care and the recent stress on a patient-centered approach mandate evaluation of current patient priorities. Methods Hospitalized and ambulatory patients at an academic medical center in central Israel were investigated. Consecutive patients (n = 274 indicated their first and second priority for a change or improvement in their medical care out of a mixed shortlist of 6 issues, 3 related to patient-physician relationship (being better informed and taking part in decisions; being seen by the same doctor each time; a longer consultation time and 3 issues related to the organizational aspect of care (easier access to specialists/hospital; shorter queue for tests; less charges for drugs. Results Getting more information from the physician and taking part in decisions was the most desirable patient choice, selected by 27.4% as their first priority. The next choices – access and queue – also relate to more patient autonomy and control over that of managed care regulations. Patients studied were least interested in continuity of care, consultation time or cost of drugs. Demographic or clinical variables were not significantly related to patients' choices. Conclusion Beyond its many benefits, being informed by their doctor and shared decision making is a top patient priority.

Most patients with epilepsy report a desire for more information on the disease and possible treatments than provided by clinicians. In the past two decades, many have turned to the internet for information, but this information is of variable accuracy and objectivity. We assessed the prevalence of internet use for gathering information about epilepsy and patient satisfaction in a sample of epilepsy patients in China. A cross-sectional multicenter study was conducted using a standard anonymous questionnaire that gathered demographic information and information on internet use. The reasons for using the internet, the sites visited, general satisfaction with the information provided, and impact on self-management were investigated. Of the 780 patients studied, 288 (36.9%) had internet access and 73% of these participants reported searching for general information on epilepsy, 64% for treatment information, 30% to prepare for actual hospital visits, 12% to communicate with other patients, 5% for purchasing products for epilepsy management, and 6% for other reasons. All of the participants used search engines. However, only 6% browsed websites recommended by their doctors and 96.8% thought the information gathered from other sites was inadequate. The internet holds great potential for informing epileptic patients about their disease and to seek social support. Governments, hospitals, doctors, and internet service providers must collaborate to ensure that this information is reliable and beneficial. Copyright © 2013 British Epilepsy Association.

Background Information is vital to cancer patients. Physician–patient communication in oncology presents specific challenges. The aim of this study was to evaluate self-reported information of cancer patients in ambulatory care at a comprehensive cancer centre and examine its possible association with patients’ demographic and clinical characteristics. Patients and methods This study included adult patients with solid tumours undergoing chemotherapy at the Institute Jules Bordet’s Day Hospital over a ten-day period. EORTC QLQ-C30 and QLQ-INFO25 questionnaires were administered. Demographic and clinical data were collected. Descriptive and inferential statistics were used. Results 101 (99%) fully completed the questionnaires. They were mostly Belgian (74.3%), female (78.2%), with a mean age of 56.9 ± 12.8 years. The most frequent tumour was breast cancer (58.4%). Patients were well-informed about the disease and treatments, but presented unmet information domains. The Jules Bordet patients desired more information on treatment side effects, long-term outcome, nutrition, and recurrence symptoms. Patients on clinical trials reported having received less information about their disease and less written information than patients outside clinical trials. Higher information levels were associated with higher quality of life (QoL) scores and higher patient satisfaction. Conclusion Patients were satisfied with the information they received and this correlated with higher QoL, but they still expressed unmet information wishes. Additional studies are required to investigate the quality of the information received by patients enrolled in clinical trials. PMID:24834120

2017-01-01

Background With online health information becoming increasingly popular among patients, concerns have been raised about the impact of patients’ Internet health information-seeking behavior on their relationship with physicians. Therefore, it is pertinent to understand the influence of online health information on the patient-physician relationship. Objective Our objective was to systematically review existing research on patients’ Internet health information seeking and its influence on the patient-physician relationship. Methods We systematically searched PubMed and key medical informatics, information systems, and communication science journals covering the period of 2000 to 2015. Empirical articles that were in English were included. We analyzed the content covering themes in 2 broad categories: factors affecting patients’ discussion of online findings during consultations and implications for the patient-physician relationship. Results We identified 18 articles that met the inclusion criteria and the quality requirement for the review. The articles revealed barriers, facilitators, and demographic factors that influence patients’ disclosure of online health information during consultations and the different mechanisms patients use to reveal these findings. Our review also showed the mechanisms in which online information could influence patients’ relationship with their physicians. Conclusions Results of this review contribute to the understanding of the patient-physician relationship of Internet-informed patients. Our main findings show that Internet health information seeking can improve the patient-physician relationship depending on whether the patient discusses the information with the physician and on their prior relationship. As patients have better access to health information through the Internet and expect to be more engaged in health decision making, traditional models of the patient-provider relationship and communication strategies must be

For patients with haematological malignancies, information on disease, prognosis, treatment and impact on quality of life is of the utmost importance. To gain insight into the perceived need for information in relation to sociodemographic and clinical parameters, comorbidity, quality of life (QoL) and information satisfaction, we compiled a questionnaire based on existing validated questionnaires. A total of 458 patients diagnosed with a haematological malignancy participated. The perceived need for information was moderate to high (40-70%). Multivariate regression analyses showed that a higher need for information was related to younger age, worse QoL, being member of a patient society and moderate comorbidity. The need for disease and treatment-related information was higher than the need for psychosocial information. A higher need for disease and treatment-related information was associated to being diagnosed with multiple myeloma. A higher need for psychosocial information was related to a lower educational level. The information provision could be improved according to 41% of the patients. Higher satisfaction with provided information was associated with better QoL. Most patients (62%) reported that they wanted to be fully informed about their illness and actively involved in treatment decision-making. The results contribute to improving patient-tailored information provision and shared decision-making in clinical practice. Copyright © 2014 John Wiley & Sons, Ltd.

The purpose of this paper is to explore library and information service impact on patient care quality. A large-scale critical incident survey of physicians and residents at 56 library sites serving 118 hospitals in the USA and Canada. Respondents were asked to base their answers on a recent incident in which they had used library resources to search for information related to a specific clinical case. Of 4,520 respondents, 75 percent said that they definitely or probably handled patient care differently using information obtained through the library. In a multivariate analysis, three summary clinical outcome measures were used as value and impact indicators: first, time saved; second, patient care changes; and third, adverse events avoided. The outcomes were examined in relation to four information access methods: first, asking librarian for assistance; second, performing search in a physical library; third, searching library's web site; or fourth, searching library resources on an institutional intranet. All library access methods had consistently positive relationships with the clinical outcomes, providing evidence that library services have a positive impact on patient care quality. Electronic collections and services provided by the library and the librarian contribute to patient care quality.

It has been shown in clinical studies that patients with congenital bicuspid aortic valves (CBAVs) develop degenerative calcification of the leaflets at young ages compared to patients with the normal tricuspid aortic valves (TAVs). It has been hypothesized that the asymmetrical geometry of the leaflets in CBAVs, flow shear stresses (SS), disturbed flow, and excessive strain rate levels are possible causes for the early calcification and stenosis. Central to the validation of this hypothesis is the need to quantify the differences in strain rate levels between the BAVs and TAVs. We simulate the CBAVs by surgically stitching two of the leaflets of a porcine aortic valve together. To quantify strain differences, we performed in-vitro experiments in both trileaflet and bileaflet valves by tracking the motion of small ink dots marked on each leaflet surface. We then used phase-locked stereo photogrammetry to reconstruct at each instant of time the 3D surface of the leaflets and measure the strain rates in both radial and circumferential directions during the whole cardiac cycle. Our results indicate that the total strain rate of the simulated BAVs is about 15 to 20% higher than the normal leaflets of TAVs at systole. In the BAVs' case, the fused leaflet stretches radially up to 25% higher than the reference length. The excessive stretching in both directions in the fused leaflet results in large changes in the flow patterns and associated wall SS.

Little is known about how patients move among information sources to fulfill unmet needs. We interviewed 43 breast, prostate, and colorectal cancer patients. Using a grounded theory approach, we identified patterns and motivations for movement among information sources. Overall, patients reported using one source (e.g., newspaper) followed by the use of another source (e.g., Internet), and five key motivations for such cross-source movement emerged. Patients' social networks often played a central role in this movement. Understanding how patients navigate an increasingly complex information environment may help clinicians and educators to guide patients to appropriate, high-quality sources.

Aim: The aims of the survey were to check that group pre-radiotherapy information sessions met patients' needs. The use of virtual technology (VT) through Patient Education And Radiotherapy Learning (PEARL) was incorporated part way through the survey period. Methods: Patients attending group pre-radiotherapy information sessions led by assistant practitioners between March and December 2014 were asked to complete questionnaires after they had attended at least five radiotherapy sessions. Key results: 305 patients attended sessions during the survey period. 129 questionnaires were distributed with 103 returned, resulting in an 80% response rate (Overall rate 34%). 102 (99%) patients responded that they were happy and comfortable to receive their radiotherapy information in a group setting. The majority of patients responded that they felt no additional information should be included. Conclusions and recommendations: The survey highlighted that almost all patients were happy to receive their information in a group setting. Patients attending non PEARL and PEARL sessions indicated high satisfaction levels with no notable differences between the groups. This has allayed MVCC staffs' original concerns that patients may find the use of VT as frightening in patient information sessions, so the centre is now confident to incorporate it in the future. The implementation of these sessions has seemed to be both feasible and an efficient use of staff time. All patients referred for radical breast radiotherapy are now invited to attend. It is recommended that regular patient experience surveys are conducted in the future to ensure they continue to meet patients' needs. - Highlights: • 102 (99%) patients responded happy to receive their information in a group setting. • 86 (83%) patients responded they felt no additional information should be included. • 58 (56%) patients provided complimentary comments about the sessions.

Objective: Readability has been claimed to be an important factor for understanding texts describing health symptoms and medications. Such texts may be a factor which indirectly affects the health of the population. Despite the expertise of physicians, the readability of information sources may be important for acquiring essential treatment information. The aim of this study was to measure the readability level of medicines promotion material in Slovenia. Methods: The Flesch readability formula was modified to comply with Slovene texts. On the basis of determining the Slovene readability algorithm, the readability ease related to the readability grade level of different Slovene texts was established. In order to estimate an adjustment of the texts to the recommended readability grade level of the targeted population, readability values of English texts were set. One sample t-test and standard deviations from the arithmetic mean values were used as statistical tests. Results: The results of the research showed low readability scores of the Slovene texts. Difficult readability values were seen in different types of examined texts: in patient information leaflets, in the summaries of product characteristics, in promotional materials, while describing over-the-counter medications and in the materials for creating disease awareness. Especially low readability values were found within the texts belonging to promotional materials intended for the physicians. None of researched items, not even for the general public, were close to primary school grade readability levels and therefore could not be described as easily readable. Conclusion: This study provides an understanding of the level of readability of selected Slovene medicines information material. It was concluded that health-related texts were not compliant with general public or with healthcare professional needs. PMID:23093886

Full Text Available The genus Zamia is morphologically and ecologically the most diverse of the order Cycadales. Throughout its history this genus has been restricted to the New World and is presently almost entirely restricted to the Neotropics. Unusual anatomical traits of the leaflets, such as the sunken stomata and thick cuticle, are common in this and related genera. The objective of this research was to study and compare the leaflet anatomy of Zamia acuminata and Z. pseudomonticola and establish possible phylogenetic relationships between the anatomical traits and the near relatives of these species. The leaf material was obtained from living plants and then processed for electron microscopy study. We found that both species are very similar to each other and to Z. fairchildiana, and that they share several unusual traits with other species of the genus, such as the parenchyma morphology, the spatial distribution of tissues between the veins and the stomata morphology. The main differences between these species were seen in their fiber clusters and in the abundance of trichome basal cells on the epidermis. The anatomical similarities between the three species could be the result of their close phylogenetic relationship and the divergences between them could be the result of recent speciation during the Pleistocene, resulting from geological changes in Southern Costa Rica.Zamia es morfológica y ecológicamente el género más diverso del orden Cycadales. Este género siempre ha estado restringido a América, pero en la actualidad habita principalmente en la región neotropical. Características anatómicas inusuales en los foliolos como los estomas hundidos y las cutículas gruesas son comunes en Zamia y géneros afines. El objetivo de este trabajo consiste en comparar la anatomía de los foliolos de Zamia acuminata y Z. pseudomonticola y establecer posibles relaciones filogenéticas entre las características anatómicas y los parientes cercanos de esta
