Dietary intervention among patients with type 2 diabetes mellitus: an e-approach
No full textmyDIDeA was a 12-months two-armed randomised controlled trial conducted in three tertiary public hospitals in Klang Valley, Malaysia. The primary outcome was the Dietary Knowledge, Attitude and Behaviour (DKAB) score, while the secondary outcomes included measures of food intake, anthropometry measurements, blood pressure and resting heart rate, some blood biomarkers and the Dietary Stages of Change (DSOC) score. The study was designed according to the recommendations of the CONSORT statement for randomised trials of non-pharmacologic treatment. The study commenced in November 2009 after obtaining the ethical approvals from relevant authorities, and the trial has been registered with Clinicaltrials.gov (NCT01246687). After being screened for eligibility, 128 patients with Type 2 Diabetes Mellitus (T2DM) from the outpatient clinics at these hospitals were recruited with informed consent, and then randomised into the e-intervention (n=66) or the control (n=62) group. The e-intervention group received an intensive six-month dietary intervention through the study website, which was developed based on various established guidelines and recommendations but personalised according to the participants’ DSOC, in addition to the usual standard treatment at the outpatient clinics. In contrast, the control group continued their usual standard treatment for patients with T2DM in the hospitals. Data were collected at baseline, six months post-intervention and at 12 months follow-up. A pre-tested and validated questionnaire was used for this purpose. The anthropometry measurements, blood pressure and resting heart rate were measured at data collection, while details on the blood biomarkers were obtained from the hospital medical records. All data were analysed with IBM® PASW® Statistics 17.0. On average, each participant logged into the website once a week and spent 11 minutes at the website per visit. myDIDeA was found to be a successful intervention programme to improve the overall DKAB score, due to the improvement in the knowledge and attitude sub-domains. Additionally, the intervention programme also successfully improved the DSOC score of the intervention group, which suggests participants were also making small but significant progress in changing their dietary behaviour. Some additional improvements in diet quality (reduction in carbohydrate and protein intake), glycaemic control and total cholesterol were also detected. myDIDeA is one of few web-delivered dietary interventions for patients with chronic disease. The reach, flexibility, accessibility and conversion of established guidelines into a more user-friendly format have contributed to the success of this intervention programme. Future related studies are suggested to emphasise on the interactivity, familiarise the participants with the system prior to the intervention, encourage self-monitoring and built the intervention on a strong theoretical background
Dietary And Lifestyle Factors Associated With Risk Ofcolorectal Adenoma In Patients At Hospital Kuala Lumpur
Get PDFCancer is now the third leading cause of death in Malaysia and one in four Malaysians is
at risk of developing cancer. In Peninsular Malaysia, there was a slight decline in
percentage of colon (-0.2%) and rectal (-0.2%) cancer incidence in males in the year 2003
compared to the previous year as reported by National Cancer Registry (2004). Yet, there
was an increase in percentages of these cancer incidences in women (+0.4% in colon
cancer and +0.7% in rectal cancer). Colorectal cancers are thought to develop over a
period of several years, and most of them develop from benign, neoplastic adenomatous
polyps (Bond, 2000). Colorectal adenomas have been shown, but not always,
significantly related to various dietary and lifestyle factors. These factors have yet to be
reported in relation to colorectal polyps in the Malaysian population. This case-control
study was carried out to determine the relationship between dietary and lifestyle
characteristics, and risk for colorectal adenomas among Malaysians. After screening for
inclusion and exclusion criteria, 11 8 men and women with good cognition and who were
at least 30 years at the time of interview and have undergone colonoscopy in Hospital
Kuala Lumpur were enrolled in the this study upon obtaining ethical clearance. Fifty nine
patients diagnosed with colorectal adenomas were recruited as case subjects, while a
similar number of patients diagnosed negative for any polyps were recruited as controls.
A structured and pre-tested interviewer administrated questionnaire was used for data
collection. The fasting blood samples were collected by trained and qualified nurse, and
analyzed using relevant analysis in the laboratory. The collected data were then analyzed
with SPSS version 12.0. Multivariate analysis concluded that the higher servings of fruits
(adjusted OR = 0.150, 95% CI = 0.052 - 0.434) and vegetables (adjusted OR = 0.344,
95% CI = 0.149 - 0.794), crude fibre intake (adjusted OR = 0.659, 95% CI = 0.481 -
0.905) and plasma levels of total cholesterol (adjusted OR = 5.370, 95% CI = 1.861 -
15.495), LDL (adjusted OR = 1.093, 95% CI = 1.022 - 2.386) and vitamin E (adjusted
OR = 0.481, 95% CI = 0.306 - 0.758) found to significantly contribute to the risk for
colorectal adenomas, upon adjusting for potential covariates. A larger study and possibly
a prospective study which recruits study subjects from various places in Malaysia will be
an excellent effort to confirm these findings. Interventions with focuses on behavioural
change may be able to reduce one's risk for colorectal adenomas which in the long-term
reduce hisher risk for developing colorectal cancer in the future
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Nutritional status and the risk for colorectal adenomas: A case-control sudy in Hospital Kuala Lumpur, Malaysia.
No full textVariations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
