    Most people with musculoskeletal problem suffer pain at multiple body sites. The most frequent form of multisite pain studied is chronic widespread pain (CWP). Focusing solely on CWP may exclude the commoner form of multisite pain which is less wide spread. Therefore, studies on multisite pain which do not consider the spatial distribution of pain can be beneficial to tackle the overall problem of musculoskeletal pain. Nevertheless, multisite pain has been defined differently in the studies among workers. The absence of uniformed definition will jeopardize the understanding of this musculoskeletal problem. A review was thus carried out to identify how multisite pain were defined, how they influenced the reported occurrence of multisite pain and whether the definition determined the physical work exposures assessed in previous studies among worker. A systematic review was initiated by the search of electronic databases for multisite pain. Articles were included and excluded based on the selection criteria. A final of nine full text articles were reviewed. It was found that the difference in the definitions lies mainly in the body sites considered and the pain characteristics. The characteristics of pain influenced the multisite pain prevalence more than the sites.It wasdifficult to conclude whether the definition used determined the physical work exposures since only five studies were involved and three of them had similar research team which may explained the usage of similar exposures. The findings from this review, however, could not be inferred due to the small number of studies involved.

    The selection criteria play an important role in the portfolio optimization
    using any ratio model. In this paper, the authors have considered the mean return as
    profit and variance of return as risk on the asset return as selection criteria, as the first
    stage to optimize the selected portfolio. Furthermore, the sharp ratio (SR) has been
    considered to be the optimization ratio model. In this regard, the historical data taken
    from Shanghai Stock Exchange (SSE) has been considered. A metaheuristic technique
    has been developed, with financial tool box available in MATLAB and the particle swarm
    optimization (PSO) algorithm. Hence, called as the hybrid particle swarm optimization
    (HPSO) or can also be called as financial tool box particle swarm optimization (FTBPSO).
    In this model, the budgets as constraint, where as two different models i.e. with
    and without short sale, have been considered. The obtained results have been compared
    with the existing literature and the proposed technique is found to be optimum and better
    in terms of profit.

    This study investigates how prioritisation in health services have influenced speech and language therapy (SLT) services in Scotland in prioritising their caseload. Additionally, it evaluates how current prioritisation systems may contribute towards the development of the SLT service in Malaysia. Health, education and social agencies in Malaysia were contacted and a literature review was conducted. Information on prioritisation systems used in Malaysia was unavailable. Prioritisation systems from seven SLT departments within Scotland were investigated, of which three SLT managers took part in semi-structured interviews. The findings show that prioritisation is influenced by a combination of factors and that the principles could only be applied to the Malaysian SLT service if consideration is given to the political, economical, social, geographical and cultural factors.

    Liver transplantation has been successfully used in the treatment of a large number of liver diseases. The largest patient group comprises patients with end stage decompensated liver disease. Decompensation is defined as the presence of cirrhosis and one or more of the following: jaundice, ascites, hepatic encephalopathy, hepatorenal syndrome or bleeding oesophageal varices. In general patients in this category should be considered for liver transplantation, if available. Guidelines for liver transplant assessment have been published by both the British Society of Gastroenterology and the American Association for the Study of Liver Disease. These guidelines provide a good basis for patient selection. As new information becomes available the indications for individual diseases may change somewhat. One of the most important changes in recent years was the introduction of the MELD/PELD scoring system. This is the model for end stage liver disease which provides a reasonably robust estimate of prognosis for individual patients. Prior to this patient waiting time on the transplant list was one of the principal determinants of priority for liver allocation. The MELD scoring system has been widely adopted with the aim of allocating the available livers to patients in the greatest clinical need.

    Radiology is important in the diagnostic assessment, treatment and monitoring progress of patients having dental and maxillofacial diseases. The central question in dental radiology is whether there is any risk with regard to low doses of radiation and what are the necessary protection needed to prevent any hazardous outcome with X-raying. With the emergence of the new millennium, major changes are happening in the field of science and technology. More efficient equipments are being discovered and more researches are being conducted to elicit better understanding of the radiation process and its effect on the human health. This article will review the latest guidelines for proper radiographic practice from the USA and Europe. It will address topics like the risks from dental radiography, selection criteria, protection for patients and staff, improvement to X-ray equipments, room dimensions and lead lining requirements. We have limited our research to intraoral, panoramic and cephalometric radiographs because these are the radiographs or images that are commonly taken in the general practice setting.

    Current selection guideline for CRT uses broad QRS duration (>120 ms) as a marker for ventricular dyssynchrony. However, more recent data supports mechanical marker specifically measured by Tissue Doppler Imaging (TDI) as a better criterion to predict response to CRT. Sixty seven patients with significant left ventricular dysfunction (EF less than 40%) and narrow QRS complex were prospectively enrolled. They underwent Tissue Doppler Imaging (TDI) study to evaluate intraventricular mechanical dyssynchrony. Dyssynchrony index which is defined as standard deviation of time to peak systolic velocity in twelve ventricular segments was measured. A value greater than 32.6 is taken to reflect significant ventricular dyssynchrony. Overall 38 patients (56.7%) demonstrated significant dyssynchrony. There was no significant correlation between QRS duration and the Ts-SD-12 (r = 0.14, p = 0.11). Ventricular mechanical dyssynchrony is common in patients with normal QRS duration. Therefore, QRS duration alone will miss a substantial proportion of suitable patients for CRT and therefore deny them this adjunct therapy. We propose echocardiographic parameters, specifically TDI, to be included in patient selection criteria for CRT.

    Combining forecast values based on simple univariate models may produce more favourable results than complex models. In this study, the results of combining the forecast values of Naïve model, Single Exponential Smoothing Model, The Autoregressive Moving Average (ARIMA) model, and Holt Method are shown to be superior to that of the Error Correction Model (ECM).Malaysia’s unemployment rates data are used in this study. The independent variable used in the ECM formulation is the industrial production index. Both data sets were collected for the months of January 2004 to December 2010. The selection criteria used to determine the best model, is the Mean Square Error (MSE), Root Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE). Initial findings showed that both time series data sets were not influenced by the seasonality effect.

    Regression testing is crucial in ensuring that modifications made did not introduce any adverse effect on the software being modified. However, regression testing suffers from execution cost and time consumption problems. Test case prioritization (TCP) is one of the techniques used to overcome these issues by re-ordering test cases based on their priorities. Model-based TCP (MB-TCP) is an approach in TCP where the software models are manipulated to perform prioritization. The issue with MB-TCP is that most of the existing approaches do not provide satisfactory faults detection capability. Besides, their granularity of test selection criteria is not very good and this can affect prioritization effectiveness. This study proposes an MB-TCP approach that can improve the faults detection performance of regression testing. It combines the implementation of two existing approaches from the literature while incorporating an additional ordering criterion to boost prioritization efficacy. A detailed empirical study is conducted with the aim to evaluate and compare the performance of the proposed approach with the selected existing approaches from the literature using the average of the percentage of faults detected (APFD) metric. Three web applications were used as the objects of study to obtain the required test suites that contained the tests to be prioritized. From the result obtained, the proposed approach yields the highest APFD values over other existing approaches which are 91%, 86% and 91% respectively for the three web applications. These higher APFD values signify that the proposed approach is very effective in revealing faults early during testing. They also show that the proposed approach can improve the faults detection performance of regression testing.

    Emphysema is a progressive unrelenting component of chronic obstructive pulmonary disease and a major source of mortality and morbidity globally. The prevalence of moderate to severe emphysema is approximately 5% in Malaysia and likely to increase in the future. Hence advanced emphysema will emerge as a leading cause of hospital admission and a major consumer of healthcare resources in this country in the future. Patients with advanced disease have a poor quality of life and reduced survival. Medical therapy has been largely ineffective for many patients however certain subgroups have disease amenable to surgical palliation. Effective surgical therapies include lung volume reduction surgery, lung transplantation and bullectomy. This article is a comprehensive evidence based review of the literature evaluating the rationale, efficacy, safety and limitations of surgery for advanced emphysema highlighting the importance of meticulous patient selection and local factors relevant to Malaysia.

    OBJECTIVE: Comprehensive diagnosis and treatment planning are essential in a successful orthodontic practice. The purpose of this study is to determine and compare intermaxillary tooth size discrepancy (IMTSD) using traditional digital caliper (DC) measurement on plaster dental models and stereomicroscopic digital dental models (SM).

    MATERIALS AND METHODS: The samples were randomly selected from different states of Pakistan. Total 7168 variables were measured on plaster dental casts (128) and SM digital dental models (128) according to the selection criteria. For IMTSD, the 6 variable measured as for anterior tooth size (maxilla, mandibular), overall tooth size (maxilla, mandibular), Bolton's anterior ratios (BAR), and Bolton's overall ratios (BOR). The independent t-test and ANOVA were used for statistical analyses.

    RESULTS: Significant sexual disparities in the sum of anterior tooth size and overall tooth size via DC and SM methods. No significant sexual disparities for BAR and BOR. No statistically significant differences were found in BAR and BOR between DC and SM. No significant differences were found on IMTSD ratio among different arch length and arch perimeters groups.

    CONCLUSIONS: Norms were developed based on DC and SM for IMTSD. Sexual disparities were observed in the sum of teeth size. However, no significant differences in BAR and BOR for IMTSD between the two methods.

    Focus group discussion is a research methodology in which a small group of participants gather to discuss a specified topic or an issue to generate data. The main characteristic of a focus group is the interaction between the moderator and the group, as well as the interaction between group members. The objective is to give the researcher an understanding of the participants' perspective on the topic in discussion. Focus groups are rapidly gaining popularity in health and medical research. This paper presents a general introduction of the use of focus groups as a research tool within the context of health research, with the intention of promoting its use among researchers in healthcare. A detailed methodology for the conduct of focus groups and analysis of focus group data are discussed. The potentials and limitations of this qualitative research technique are also highlighted.

    The selection of landfill, which happens to be an environmental issue, has attracted
    the attention of many researchers from the fields of waste management and
    environmental sciences worldwide. Hence, in the attempt to overcome this problem,
    some decision-making techniques, including Geographic Information Systems (GIS)
    and Multi-Criteria Decision Analysis (MCDA), have been widely utilized in prior studies,
    where multiple criteria, particularly in site selection process, have been employed.
    With that, this article identifies the selection criteria for landfill selection and presents
    a review concerning decision-making techniques that have been used in past studies
    for two important phases involved during the process of site selection, namely, (1)
    preliminary site screening, and (2) assessment of site suitability. As such, some 82
    articles chosen from 34 peer-reviewed journals had been investigated in detail. The
    results showed that 42.68% of the selected articles integrated GIS and MCDA
    techniques to solve the problem of landfill site selection, and this is followed by
    integrating GIS and fuzzy MCDA technique (18.29%). Both these techniques are indeed
    powerful tools that can guide decision-makers to solve problems in making decisions
    on the basis of various criteria under certainty and uncertainty results, mainly involving
    environmental issues.

    Placenta previa is a condition when the placental tissue extends over the internal cervical os. It is associated with
    maternal and fetal morbidity and mortality. With intrauterine death, the mode of delivery will be more difficult to
    decide. Here, we report a case of 30 years old G3P2 with placenta previa major diagnosed with intrauterine death at
    29 weeks gestation who was managed conservatively and delivered vaginally with minimal complication. A good
    patient selection and thorough counseling, patient with placenta previa major and intrauterine death still can be safely
    delivered vaginally.

    Diabetes self-management offers an opportunity to patients to be actively involved in managing their conditions and modifying lifestyle behaviors to attain positive health outcomes. With the unprecedented growth of mobile technology, smartphone plays a role in supporting diabetes self-management. Nonetheless, selecting appropriate mobile applications (apps) is challenging for patients. Thus, this study aimed to evaluate and compare the contents and features of mobile medical apps for diabetes self-management. Of 346 commercial apps, 16 (16%) and 19 (7.72%) of the diabetes apps found in Apple and Google Play stores, respectively, were included based on the selection criteria and individually scored for the availability of 8 main features of diabetes self-management. The apps supported self-management by offering features such as free installation, less than 50 MB space used, offline use, automated data entry, data export and sharing, educational tool, and advice. Of the 8 evaluated features, only 11 (31.4%) apps had a score of 5 whereas 7 (20%) apps scored the lowest, with a score of 3. The majority of apps were free, required no Internet connectivity to use and were less than 50 MB in size. Our findings showed that the design of diabetes mobile apps focused on reporting and setting reminders, rather than providing personalized education or therapeutic support. In the future, the design of apps could be improved to integrate patients' needs, usability for disease management, and lifestyle modifications.

    A search for a signal consistent with the type-III seesaw mechanism in events with three or more electrons or muons is presented. The data sample consists of proton-proton collisions at sqrt[s]=13  TeV collected by the CMS experiment at the LHC in 2016 and corresponds to an integrated luminosity of 35.9  fb^{-1}. Selection criteria based on the number of leptons and the invariant mass of oppositely charged lepton pairs are used to distinguish the signal from the standard model background. The observations are consistent with the expectations from standard model processes. The results are used to place limits on the production of heavy fermions of the type-III seesaw model as a function of the branching ratio to each lepton flavor. In the scenario of equal branching fractions to each lepton flavor, heavy fermions with masses below 840 GeV are excluded. This is the most sensitive probe to date of the type-III seesaw mechanism.

    The behaviour of many financial time series cannot be modeled solely by linear time series model. Phenomena such as mean reversion, volatility of stock markets and structural breaks cannot be modelled implicitly using simple linear time series model. Thus, to overcome this problem, nonlinear time series models are typically designed to accommodate these nonlinear features in the data. In this paper, we use portmanteau test and structural change test to detect nonlinear feature in three ASEAN countries exchange rates (Malaysia, Singapore and Thailand). It is found that the null hypothesis of linearity is rejected and there is evidence of structural breaks in the exchange rates series. Therefore, the decision of using regime switching model in this study is justified. Using model selection criteria (AIC, SBC, HQC), we compare the in-sample fitting between two types of regime switching model. The two regime switching models we considered were the Self-Exciting Threshold Autoregressive (SETAR) model and the Markov switching Autoregressive (MS-AR) model where these models can explain the abrupt changes in a time series but differ as how they model the movement between regimes. From the AIC, SBC and HQC values, it is found that the MS -AR model is the best fitted model for all the return series. In addition, the regime switching model also found to perform better than simple autoregressive model in in-sample fitting. This result justified that nonlinear model give better in-sample fitting than linear model.

    Objective: To develop an innovative prioritisation process to identify topics for new or updated systematic reviews of tinnitus research.Design: A two-stage prioritisation process was devised. First, a scoping review assessed the amount of randomized controlled trial-level evidence available. This enabled development of selection criteria for future reviews, aided the design of template protocol and suggested the scale of work that would be required to conduct these reviews. Second, using the pre-defined primary and secondary criteria, interventions were prioritised for systematic review.Study sample: Searches identified 1080 records. After removal of duplicates and out of scope works, 437 records remained for full data charting.Results: The process was tested, using subjective tinnitus as the clinical condition and using Cochrane as the systematic review platform. The criteria produced by this process identified three high priority reviews: (1) Sound therapy using amplification devices and/or sound generators; (2) Betahistine and (3) Cognitive behaviour therapy. Further secondary priorities were: (4) Gingko biloba, (5) Anxiolytics, (6) Hypnotics, (7) Antiepileptics and (8) Neuromodulation.Conclusions: A process was developed which successfully identified priority areas for Cochrane systematic reviews of interventions for subjective tinnitus. This technique could easily be transferred to other conditions and other types of systematic reviews.

    BACKGROUND: One-anastomosis gastric bypass (OAGB-MGB) is currently the third performed primary bariatric surgical procedure worldwide. However, the procedure is hampered by numerous controversies and there is considerable variability in surgical technique, patient selection, and pre- and postoperative care among the surgeons performing this procedure. This paper reports the results of a modified Delphi consensus study organized by the International Federation for Surgery of Obesity and Metabolic Disorders (IFSO).

    METHODS: Fifty-two internationally recognized bariatric experts from 28 countries convened for voting on 90 consensus statements over two rounds to identify those on which consensus could be reached. Inter-voter agreement of ≥ 70% was considered consensus, with voting participation ≥ 80% considered a robust vote.

    RESULTS: At least 70% consensus was achieved for 65 of the 90 questions (72.2% of the items), 61 during the first round of voting and an additional four in the second round. Where consensus was reached on a binary agree/disagree or yes/no item, there was agreement with the statement presented in 53 of 56 instances (94.6%). Where consensus was reached on a statement where options favorable versus unfavorable to OAGB-MGB were provided, including statements in which OAGB-MGB was compared to another procedure, the response option favorable to OAGB-MGB was selected in 13 of 23 instances (56.5%).

    CONCLUSION: Although there is general agreement that the OAGB-MGB is an effective and usually safe option for the management of patients with obesity or severe obesity, numerous areas of non-consensus remain in its use. Further empirical data are needed.
