Obesity and risk factors for cardiovascular disease and type 2 diabetes: Investigating the role of physical activity and sedentary behaviour in mid-life in the 1958 British cohort.

A key public health priority is to minimise obesity-related health consequences. We aim to establish whether physical activity (PA) or less sedentary behaviour ameliorate associations of obesity with biomarkers for cardiovascular disease (CVD) and type 2 diabetes

A cost-effectiveness analysis of teledietetics in short-, intermediate-, and long-term weight reduction

Objective To evaluate the effectiveness of teledietetics in weight loss for 24 weeks and the cost-effectiveness of weight loss between face-to-face and teledietetics services. Study setting The study was conducted at a community health center and a community dietetics clinic. Study design The study was a quasiexperimental design. Methods Fifty adults aged 20–50 with a BMI ≥23 participated in the study. The face-to-face (FD) group received 12 dietary counselling sessions and recorded their diet in a log book. The teledietetics (TD) group attended three group nutrition seminars and recorded their diet on a Web-based platform. Changes in variables were compared using an independent t-test. Direct and indirect costs were applied to compute cost-effectiveness ratios. Results At week 6, the FD group showed greater reductions in all variables than did the TD group. At week 12, the effects reversed. At week 24, the accumulated reductions in weight and fat in the TD group were significantly higher than those in the FD group (all at p < 0.0001). The observed direct costs for 1% weight loss and 1% fat loss were USD 28.24 and USD17.09, respectively. Conclusion A dietetic service delivered as a teledietetics model is more cost-effective than the face-to-face dietetics model in weight reduction.postprin

Protecting digital data privacy in Computer Forensic Examination

Session 1: Forensic Modeling and Framework: no. 3Privacy is a fundamental human right defined in the Universal Declaration of Human Rights. To enable the protection of data privacy, personal data that are not related to the investigation subject should be excluded during computer forensic examination. In the physical world, protection of privacy is controlled and regulated in most countries by laws. Legislation for handling private data has been established in various jurisdictions. In the modern world, the massive use of computers generates a huge amount of private data and there is correspondingly an increased expectation to recognize and respect human rights in digital investigation. However, there does not exist a forensically sound model for protecting private data in the context of digital investigation, and it poses a threat to privacy if the investigation involves the processing of such kind of data. In this paper, we try to address this important issue and present a cryptographic model designed to be incorporated into the current digital investigation framework, thereby adding a possible way to protect data privacy in digital investigation. © 2011 IEEE.link_to_subscribed_fulltex

Health-related quality of life in patients with colorectal neoplasm and cost-effectiveness of colorectal cancer screening in Hong Kong

Key Messages 1. Compared with the Hong Kong general population norm, Chinese patients with colorectal neoplasm (CRN) reported worse physical health-related quality of life (HRQOL) but better mental HRQOL and comparable health preference scores. 2. The CRN stage at diagnosis was the most significant determinant of HRQOL. Colorectal cancer was associated with worse physical HRQOL and health preference scores. 3. Immunochemical faecal occult blood testing every 2 years is the most cost-effective colorectal cancer screening strategy, with an incremental cost-effectiveness ratio of HK$43 660 per quality-adjusted life year gained.published_or_final_versio

Tai-chi for residential patients with schizophrenia on movement coordination, negative symptoms, and functioning: a pilot randomized controlled trial

Objective. Patients with schizophrenia residing at institutions often suffer from negative symptoms, motor, and functional impairments more severe than their noninstitutionalized counterparts. Tai-chi emphasizes body relaxation, alertness, and movement coordination with benefits to balance, focus, and stress relief. This pilot study explored the efficacy of Tai-chi on movement coordination, negative symptoms, and functioning disabilities towards schizophrenia. Methods. A randomized waitlist control design was adopted, where participants were randomized to receive either the 6-week Tai-chi program and standard residential care or only the latter. 30 Chinese patients with schizophrenia were recruited from a rehabilitation residency. All were assessed on movement coordination, negative symptoms, and functional disabilities at baseline, following intervention and 6 weeks after intervention. Results. Tai-chi buffered from deteriorations in movement coordination and interpersonal functioning, the latter with sustained effectiveness 6 weeks after the class was ended. Controls showed marked deteriorations in those areas. The Tai-chi group also experienced fewer disruptions to life activities at the 6-week maintenance. There was no significant improvement in negative symptoms after Tai-chi. Conclusions. This study demonstrated encouraging benefits of Tai-chi in preventing deteriorations in movement coordination and interpersonal functioning for residential patients with schizophrenia. The ease of implementation facilitates promotion at institutional psychiatric services.published_or_final_versio

Protecting digital legal professional privilege LPP data

The Best Paper AwardTo enable free communication between legal advisor and his client for proper functioning of the legal system, certain documents, known as Legal professional privilege (LPP) documents, can be excluded as evidence for prosecution. In physical world, protection of LPP information is well addressed and proper procedure for handling LPP articles has been established. However, there does not exist a forensically sound procedure for protecting 'digital' LPP information. In this paper, we try to address this important, but rarely addressed, issue. We point out the difficulties of handling digital LPP data and discuss the shortcomings of the current practices, then we propose a feasible procedure for solving this problem. © 2008 IEEE.published_or_final_versionThe 3rd International Workshop on Systematic Approaches to Digital Forensic Engineering (IEEE/SADFE 2008), Oakland, CA., 22 May 2008.
