    A major issue of machinery fault diagnosis using vibration signals is that it is over-reliant on personnel knowledge and experience in interpreting the signal. Thus, machine learning has been adapted for machinery fault diagnosis. The quantity and quality of the input features, however, influence the fault classification performance. Feature selection plays a vital role in selecting the most representative feature subset for the machine learning algorithm. In contrast, the trade-off relationship between capability when selecting the best feature subset and computational effort is inevitable in the wrapper-based feature selection (WFS) method. This paper proposes an improved WFS technique before integration with a support vector machine (SVM) model classifier as a complete fault diagnosis system for a rolling element bearing case study. The bearing vibration dataset made available by the Case Western Reserve University Bearing Data Centre was executed using the proposed WFS and its performance has been analysed and discussed. The results reveal that the proposed WFS secures the best feature subset with a lower computational effort by eliminating the redundancy of re-evaluation. The proposed WFS has therefore been found to be capable and efficient to carry out feature selection tasks.

    BACKGROUND: Aging is often associated with various underlying comorbidities that warrant the use of multiple medications. Various interventions, including medication reviews, to optimize pharmacotherapy in older people residing in aged care facilities have been described and evaluated. Previous systematic reviews support the positive impact of various medication-related interventions but are not conclusive because of several factors.

    OBJECTIVES: The current study aimed to assess the impact of medication reviews in aged care facilities, with additional focus on the types of medication reviews, using randomized controlled trials (RCTs) and observational studies.

    METHODS: A systematic searching of English articles that examined the medication reviews conducted in aged care facilities was performed using the following databases: PubMed, CINAHL, IPA, TRiP, and the Cochrane Library, with the last update in December 2015. Extraction of articles and quality assessment of included articles were performed independently by 2 authors. Data on interventions and outcomes were extracted from the included studies. The SIGN checklist for observational studies and the Cochrane Collaboration's tool for assessing risk of bias in RCTs were applied. Outcomes assessed were related to medications, reviews, and adverse events.

    RESULTS: Because of the heterogeneity of the measurements, it was deemed inappropriate to conduct a meta-analysis and thus a narrative approach was employed. Twenty-two studies (10 observational studies and 12 controlled trials) were included from 1141 evaluated references. Of the 12 trials, 8 studies reported findings of pharmacist-led medication reviews and 4 reported findings of multidisciplinary team-based reviews. The medication reviews performed in the included trials were prescription reviews (n = 8) and clinical medication reviews (n = 4). In the case of the observational studies, the majority of the studies (8/12 studies) reported findings of pharmacist-led medication reviews, and only 2 studies reported findings of multidisciplinary team-based reviews. Similarly, 6 studies employed prescription reviews, whereas 4 studies employed clinical medication reviews. The majority of the recommendations put forward by the pharmacist or a multidisciplinary team were accepted by physicians. The number of prescribed medications, inappropriate medications, and adverse outcomes (eg, number of deaths, frequency of hospitalizations) were reduced in the intervention group.

    CONCLUSION: Medication reviews conducted by pharmacists, either working independently or with other health care professionals, appear to improve the quality of medication use in aged care settings. However, robust conclusions cannot be drawn because of significant heterogeneity in measurements and potential risk for biases.

    BACKGROUND: The chloroplast genome of Gracilaria firma was sequenced in view of its role as an economically important marine crop with wide industrial applications. To date, there are only 15 chloroplast genomes published for the Florideophyceae. Apart from presenting the complete chloroplast genome of G. firma, this study also assessed the utility of genome-scale data to address the phylogenetic relationships within the subclass Rhodymeniophycidae. The synteny and genome structure of the chloroplast genomes across the taxa of Eurhodophytina was also examined.

    RESULTS: The chloroplast genome of Gracilaria firma maps as a circular molecule of 187,001 bp and contains 252 genes, which are distributed on both strands and consist of 35 RNA genes (3 rRNAs, 30 tRNAs, tmRNA and a ribonuclease P RNA component) and 217 protein-coding genes, including the unidentified open reading frames. The chloroplast genome of G. firma is by far the largest reported for Gracilariaceae, featuring a unique intergenic region of about 7000 bp with discontinuous vestiges of red algal plasmid DNA sequences interspersed between the nblA and cpeB genes. This chloroplast genome shows similar gene content and order to other Florideophycean taxa. Phylogenomic analyses based on the concatenated amino acid sequences of 146 protein-coding genes confirmed the monophyly of the classes Bangiophyceae and Florideophyceae with full nodal support. Relationships within the subclass Rhodymeniophycidae in Florideophyceae received moderate to strong nodal support, and the monotypic family of Gracilariales were resolved with maximum support.

    CONCLUSIONS: Chloroplast genomes hold substantial information that can be tapped for resolving the phylogenetic relationships of difficult regions in the Rhodymeniophycidae, which are perceived to have experienced rapid radiation and thus received low nodal support, as exemplified in this study. The present study shows that chloroplast genome of G. firma could serve as a key link to the full resolution of Gracilaria sensu lato complex and recognition of Hydropuntia as a genus distinct from Gracilaria sensu stricto.

    BACKGROUND: Return to work is an important aspect for cardiac rehabilitation following a major cardiac event.

    OBJECTIVE: The aim was to understand the local prevalence and factors associated with returning to work in Malaysia after a cardiac event.

    METHODS: A cross sectional design was used. All patients attending the cardiac rehabilitation program after major cardiac event during an 11-months period (2011-2012) were included. Data relating to socio-demographic, work-related, risk factors and acute myocardial infarction were collected. The SF-36 questionnaire was used to assess quality of life. Regression analysis was used to determine the predicting factors to return to work.

    RESULTS: A total of 398 files were screened, 112 respondents agreed to participate giving a response rate of 47.3%. The prevalence of returned to work (RTW) was 66.1% [95% CI: 57.2-75.0]. Factors associated with work resumption were age (Adj. OR: 0.92 (95% CI: 0.84-0.99), diabetes mellitus (Adj. OR: 3.70, 95% CI: 1.35-10.12), Mental Component Summary (MCS) score (Adj. OR: 1.05 (95% CI: 1.01-1.09) and baseline angiography findings. Patients with single vessel and two vessel disease were 8.9 times and 3.78 times more likely to return to work compared to those with 3 vessels (Adj. OR: 8.90 (95% CI: 2.29-34.64) and Adj. OR: 3.78, (95% CI: 1.12, 12.74).

    CONCLUSIONS: We proposed a cardiac rehabilitation program to emphasize mental health as it may improve successful return to work after cardiac event.

    BACKGROUND: Working in a closed environment for more than 7-8 hours can affect both psychological and physical health among kindergarten workers.
    OBJECTIVE: To determine the prevalence of musculoskeletal disorders (MSD) and depression as well as the correlation between them, if any, among kindergarten workers.
    METHODS: In a cross-sectional observation, one hundred and five healthy female staff members (age: 34.27±7.01 year, working duration: 7.42±0.81 hr/d, BMI: 24.50±2.61 kg/m2 (mean±SD)), who have had at least one year of working experience, were selected randomly from 10 kindergartens. The subjects completed both the Cornell musculoskeletal and Patient Health (PHQ-9) questionnaires to enable the assessments of MSD and depression scores accordingly. The correlation between both questionnaires was then measured to find any links. To assess the reliability of Farsi-language versions of the Cornell questionnaire and PHQ-9, the Inter-class Correlation Co-efficient (ICC) was measured through test-retest with 1-week delay and the prevalence of MSD and depression were subsequently assessed as well.
    RESULTS: The Inter-class Correlation Co-efficient (ICC) illustrated that the Farsi version of MSD instruments showed high levels of repeatability. The ICC coefficient was (0.932-0.987, p

    Campylobacter is a major foodborne pathogen frequently associated with human bacterial gastroenteritis in the world. This study was conducted to determine the prevalence and antibiotic resistance of Campylobacter spp. in the beef food system in Malaysia. A total of 340 samples consisting of cattle feces (n = 100), beef (n = 120) from wet markets and beef (n = 120) from hypermarkets were analyzed for Campylobacter spp. The overall prevalence of Campylobacter was 17.4%, consisting of 33% in cattle fecal samples, 14.2% in raw beef from wet market and 7.5% in raw beef from the hypermarket. The multiplex-polymerase chain reaction (PCR) identified 55% of the strains as C. jejuni, 26% as C. coli, and 19% as other Campylobacter spp. A high percentage of Campylobacter spp. were resistant to tetracycline (76.9%) and ampicillin (69.2%), whilst low resistance was exhibited to chloramphenicol (7.6%). The MAR Index of Campylobacter isolates from this study ranged from 0.09 to 0.73. The present study indicates the potential public health risk associated with the beef food system, hence stringent surveillance, regulatory measures, and appropriate interventions are required to minimize Campylobacter contamination and prudent antibiotic usage that can ensure consumer safety.

    Background: After an environmental disaster, the affected community is at increased risk for persistent abdominal pain but mechanisms are unclear. Therefore, our study aimed to determine association between abdominal pain and poor water, sanitation and hygiene (WaSH) practices, and if small intestinal bacterial overgrowth (SIBO) and/or gut dysbiosis explain IBS, impaired quality of life (QOL), anxiety and/or depression after a major flood.

    Results: New onset abdominal pain, IBS based on the Rome III criteria, WaSH practices, QOL, anxiety and/or depression, SIBO (hydrogen breath testing) and stools for metagenomic sequencing were assessed in flood victims. Of 211 participants, 37.9% (n = 80) had abdominal pain and 17% (n = 36) with IBS subtyped diarrhea and/or mixed type (n = 27 or 12.8%) being the most common. Poor WaSH practices and impaired quality of life during flood were significantly associated with IBS. Using linear discriminant analysis effect size method, gut dysbiosis was observed in those with anxiety (Bacteroidetes and Proteobacteria, effect size 4.8), abdominal pain (Fusobacteria, Staphylococcus, Megamonas and Plesiomonas, effect size 4.0) and IBS (Plesiomonas and Trabulsiella, effect size 3.0).

    Conclusion: Disturbed gut microbiota because of environmentally-derived organisms may explain persistent abdominal pain and IBS after a major environmental disaster in the presence of poor WaSH practices.

    Strain CCMM B554, also known as FSM-MA, is a soil dwelling and nodule forming, nitrogen-fixing bacterium isolated from the nodules of the legume Medicago arborea L. in the Maamora Forest, Morocco. The strain forms effective nitrogen fixing nodules on species of the Medicago, Melilotus and Trigonella genera and is exceptional because it is a highly effective symbiotic partner of the two most widely used accessions, A17 and R108, of the model legume Medicago truncatula Gaertn. Based on 16S rRNA gene sequence, multilocus sequence and average nucleotide identity analyses, FSM-MA is identified as a new Ensifer meliloti strain. The genome is 6,70 Mbp and is comprised of the chromosome (3,64 Mbp) harboring 3574 predicted genes and two megaplasmids, pSymA (1,42 Mbp) and pSymB (1,64 Mbp) with respectively 1481 and 1595 predicted genes. The average GC content of the genome is 61.93%. The FSM-MA genome structure is highly similar and co-linear to other E. meliloti strains in the chromosome and the pSymB megaplasmid while, in contrast, it shows high variability in the pSymA plasmid. The large number of strain-specific sequences in pSymA as well as strain-specific genes on pSymB involved in the biosynthesis of the lipopolysaccharide and capsular polysaccharide surface polysaccharides may encode novel symbiotic functions explaining the high symbiotic performance of FSM-MA.

    Ganoderma boninense, the main causal agent of oil palm (Elaeis guineensis) basal stem rot (BSR), severely reduces oil palm yields around the world. To reduce reliance on fungicide applications to control BSR, we are investigating the efficacy of alternative control methods, such as the application of biological control agents. In this study, we used four Streptomyces-like actinomycetes (isolates AGA43, AGA48, AGA347 and AGA506) that had been isolated from the oil palm rhizosphere and screened for antagonism towards G. boninense in a previous study. The aim of this study was to characterize these four isolates and then to assess their ability to suppress BSR in oil palm seedlings when applied individually to the soil in a vermiculite powder formulation. Analysis of partial 16S rRNA gene sequences (512 bp) revealed that the isolates exhibited a very high level of sequence similarity (> 98%) with GenBank reference sequences. Isolates AGA347 and AGA506 showed 99% similarity with Streptomyces hygroscopicus subsp. hygroscopicus and Streptomyces ahygroscopicus, respectively. Isolates AGA43 and AGA48 also belonged to the Streptomyces genus. The most effective formulation, AGA347, reduced BSR in seedlings by 73.1%. Formulations using the known antifungal producer Streptomyces noursei, AGA043, AGA048 or AGA506 reduced BSR by 47.4, 30.1, 54.8 and 44.1%, respectively. This glasshouse trial indicates that these Streptomyces spp. show promise as potential biological control agents against Ganoderma in oil palm. Further investigations are needed to determine the mechanism of antagonism and to increase the shelf life of Streptomyces formulations.

    BACKGROUND: Skin is the largest and most visible organ of the body. Many of its functions include temperature regulation, immunity from microorganisms, maintaining electrolyte balance, and protection from physical injuries, chemical agents and ultraviolet (UV) radiation. Aging occurs in every layer of the skin, primarily due to the degradation of its components. Induction of degradative enzymes and the abundant production of reactive oxygen species lead to skin aging. Understanding the complexity of skin structure and factors contributing to the skin aging will help us impede the aging process. Applications of anti-aging products are a common method to prevent or repair damages that lead to aging.

    CONCLUSION: This review will provide information on the causes and indicators of skin aging as well as examine studies that have used plants to produce anti-aging products.

    Chronic wounds which include diabetic foot ulcer (DFU), pressure ulcer, and arterial or venous ulcers compel a significant burden to the patients, healthcare providers, and the healthcare system. Chronic wounds are characterized by an excessive persistent inflammatory phase, prolonged infection, and the failure of defense cells to respond to environmental stimuli. Unlike acute wounds, chronic nonhealing wounds pose a substantial challenge to conventional wound dressings, and the development of novel and advanced wound healing modalities is needed. Toward this end, numerous conventional wound-healing modalities have been evaluated in the management of nonhealing wounds, but a multifaceted approach is lacking. Therefore, this review aims to compile and explore the wide therapeutic algorithm of current and advanced wound healing approaches to the treatment of chronic wounds. The algorithm of chronic wound healing techniques includes conventional wound dressings; approaches based on autografts, allografts, and cultured epithelial autografts; and recent modalities based on natural, modified or synthetic polymers and biomaterials, processed mutually in the form of hydrogels, films, hydrocolloids, and foams. Moreover, this review also explores the promising potential of advanced drug delivery systems for the sustained delivery of growth factors, curcumin, aloe vera, hyaluronic acid, and other bioactive substances as well as stem cell therapy. The current review summarizes the convincing evidence for the clinical dominance of polymer-based chronic wound healing modalities as well as the latest and innovative therapeutic strategies for the treatment of chronic wounds.

    This study was conducted to evaluate the mycochemical composition and antiglycemic and antioxidant activities of Ganoderma neo-japonicum hot aqueous extracts, prepared at different boiling durations, and polysaccharides isolated from them. Ground basidiocarps of G. neo-japonicum were double-boiled at 100°C for 0.5, 3, or 4 hours, and the antiglycemic activity was assessed by α-amylase and α-glucosidase enzyme inhibition assays. The antioxidant capacity of the crude hot aqueous extracts (AE-1, AE-2, AE-3) was assessed by DPPH and ABTS radical scavenging and ferric-reducing antioxidant power assays. The total phenolics, protein, and sugar in the crude extracts were also determined. The hot aqueous extract (AE-3) containing a significant amount of total sugar and having enhanced antiglycemic and antioxidant activities was selected for polysaccharide isolation. The isolated crude polysaccharide was separated and purified using diethylaminoethyl-cellulose-52 and Sepharose 6B column chromatography. Fourier transform infrared spectroscopy studies of the purified polysaccharide fraction (PF) showed the presence of typical bands corresponding to polysaccharides. The estimated β-glucan concentration in the PF was 39.26%. In general, the PF exhibited significantly lower antioxidant activity than AE-3. Nevertheless, its potency in inhibiting carbohydratehydrolyzing enzymes may have potential in the management of diabetes mellitus.

    The impacts of climate changes on cities, which are home to over half of the world's population, are already being felt. In many cases, the intensive speed with which urban centres have been growing means that little attention has been paid to the role played by climatic factors in maintaining quality of life. Among the negative consequences of rapid city growth is the expansion of the problems posed by urban heat islands (UHIs), defined as areas in a city that are much warmer than other sites, especially in comparison with rural areas. This paper analyses the consistency of the UHI-related literature in three stages: first it outlines its characteristics and impacts in a wide variety of cities around the world, which poses pressures to public health in many different countries. Then it introduces strategies which may be employed in order to reduce its effects, and finally it analyses available tools to systematize the initial high level assessment of the phenomenon for multidisciplinary teams involved in the urban planning process. The analysis of literature on the characteristics, impacts, strategies and digital tools to assess on the UHI, reveals the wide variety of parameters, methods, tools and strategies analysed and suggested in the different studies, which does not always allow to compare or standardize the diagnosis or solutions.

    Smoking is the leading preventable cause of non-communicable disease mortality worldwide. Therefore, effort for the effective measure in smoking cessation is important. However, the central problem in the nicotine addiction treatment is relapse. A retrospective cohort study was done at Tanglin Quit Smoking Clinic to determine the outcome of smoking cessation and its predictors. A cohort of 770 smokers between 2008 and 2015 were identified through simple random sampling. Smokers were defined as current smoker, while smoking abstinence is defined as cessation more than 6 months and relapse as any smoking episode even a puff since the quit date. Majority were Malays, Muslims and had secondary or higher education. The mean initiating age for smoking was 17.6 years old, with majority smoke between 11 to 20 sticks, and had high nicotine dependence score (43%). At the end of the study 52.5% of them abstinence from smoking. The predictors for smoking cessation were number of quit attempt (1 to 10 times) (AOR = 1.582, 95% CI = 1.012-2.472) and pharmacotherapy (AOR = 0.711, 95% CI=0.511-0.989). More frequent follow up was required during the first crucial 6 months to prevent relapse. Number of follow up can enhance not only the medication compliance but also motivational aspect to smokers to reduce relapse rates. Healthcare provider should give extra attention to the potential relapser especially to those who attempt for the first time.
