Quality and accuracy assessment of nutrition information on the Web for cancer prevention

Shahar S, Shirley N, Noah SA

Inform Health Soc Care, 2013 Jan;38(1):15-26.
PMID: 22957981 DOI: 10.3109/17538157.2012.710684

This study aimed to assess the quality and accuracy of nutrition information about cancer prevention available on the Web. The keywords 'nutrition + diet + cancer + prevention' were submitted to the Google search engine. Out of 400 websites evaluated, 100 met the inclusion and exclusion criteria and were selected as the sample for the assessment of quality and accuracy. Overall, 54% of the studied websites had low quality, 48 and 57% had no author's name or information, respectively, 100% were not updated within 1 month during the study period and 86% did not have the Health on the Net seal. When the websites were assessed for readability using the Flesch Reading Ease test, nearly 44% of the websites were categorised as 'quite difficult'. With regard to accuracy, 91% of the websites did not precisely follow the latest WCRF/AICR 2007 recommendation. The quality scores correlated significantly with the accuracy scores (r = 0.250, p
A Flowmeter Technique to Exclude Internal Mammary Artery Anastomosis Error in an Arrested Heart

Hashim SA, Amin MA, Nair A, Raja Mokhtar RA, Krishnasamy S, Cheng K

Heart Lung Circ, 2018 May;27(5):e59-e63.

The revision of an internal mammary artery graft anastomosis because of a technical error can be time-consuming and complicated and may lead to complications. Here, we describe the technical details and our early experience of using a standard transit-time flowmeter to exclude technical errors and facilitate rapid decision making for anastomosis revision in an arrested heart during aortic cross-clamping in the absence of ultrasound guidance.
DietPal: a Web-based dietary menu-generating and management system

Noah SA, Abdullah SN, Shahar S, Abdul-Hamid H, Khairudin N, Yusoff M, et al.

Attempts in current health care practice to make health care more accessible, effective, and efficient through the use of information technology could include implementation of computer-based dietary menu generation. While several of such systems already exist, their focus is mainly to assist healthy individuals calculate their calorie intake and to help monitor the selection of menus based upon a prespecified calorie value. Although these prove to be helpful in some ways, they are not suitable for monitoring, planning, and managing patients' dietary needs and requirements. This paper presents a Web-based application that simulates the process of menu suggestions according to a standard practice employed by dietitians.
Effect of implantation site on outcome of tissue-engineered vascular grafts

Sologashvili T, Saat SA, Tille JC, De Valence S, Mugnai D, Giliberto JP, et al.

OBJECTIVE: Vascular prostheses for small caliber bypass grafts in cardiac and vascular diseases or for access surgery are still missing. Poly (Ɛ-caprolactone) (PCL) has been previously investigated by our group and showed good biocompatibility and mechanical properties in vitro and rapid endothelialisation, cellular infiltration and vascularisation in vivo yielding optimal patency in the abdominal aortic position. The aim of the present study is to evaluate our PCL graft in the carotid position and to compare its outcome to the grafts implanted in the abdominal aortic position.
METHODS: PCL grafts (1 mm ID/10 mm long) were implanted into the left common carotid artery in 20 Sprague-Dawley rats and compared to our previously published series of abdominal aortic implants. The animals were followed up to 3, 6, 12 and 24 weeks. At each time point, in vivo compliance, angiography and histological examination with morphology were performed.
RESULTS: PCL grafts showed good mechanical properties and ease of handling. The average graft compliance was 14.5 ± 1.7%/ mmHg compared to 7.8 ± 0.9% for the abdominal position and 45.1 ± 3.2%/ mmHg for the native carotid artery. The overall patency for the carotid position was 65% as compared to 100% in the abdominal position. Complete endothelialisation was achieved at 3 weeks and cell invasion was more rapid than in the aortic position. In contrast, intimal hyperplasia (IH) and vascular density were less pronounced than in the aortic position.
CONCLUSION: Our PCL grafts in the carotid position were well endothelialised with early cellular infiltration, higher compliance, lower IH and calcification compared to the similar grafts implanted in the aortic position. However, there was a higher occlusion rate compared to our abdominal aorta series. Anatomical position, compliance mismatch, flow conditions may answer the difference in patency seen.

INTRODUCTION: There has been a paradigm shift in the management of acquired sensory neural deafness in the past 30years. This is due to the emergence of implantable hearing devices such as the cochlear implant. The objective of this study is to identify surgical and functional outcomes of post-lingual and cross-over patients implanted with a cochlear implant under the National Ministry of Heath Cochlear Implant (CI) Program between 2009-2013.
MATERIALS AND METHODS: We retrospectively reviewed all postlingual and cross-over recipients of cochlear implants under the National Ministry of Heath CI Programme from 2009 to 2013. The outcomes measured were surgical complications and functional outcome. Surgical complications were divided into major and minor complications. Functional outcomes were measured using Categorical Auditory Performances (CAP) scale.
RESULTS: A total of 41 post-lingual and 15 cross-over patients were implanted between 2009 and 2013. The age of implantees ranged from 3.6 years to 63.2 years old. There were two major complications (3.6%), one is a case of electrode migration at three months post implantation, and six months post second implantation. Another was a case of device failure at about one-year post implantation. Both patients were reimplanted in the same ear. There was no minor complication. The CAP score for both groups (overall) showed significant improvement with 96.4% achieved CAP score of five and above at 24 months after implantation (p<0.001). The CAP score showed marked improvement at the first 6 months post implantation and continued to improve with time in both groups.
CONCLUSION: The Malaysian National Ministry of Health Cochlear implant (CI) Program between 2009-2013 has been a successful programme with good surgical and functional outcomes among the post lingual and cross-over patients.
