    Kenaf (Hibiscus cannabinus L.), a potential fibre crop with a desirably high growth rate, could serve as a sustainable feedstock in the production of xylitol. In this work, the extraction of soluble products of kenaf through dilute nitric-acid hydrolysis was elucidated with respect to three parameters, namely temperature, residence time, and acid concentration. The study will assist in evaluating the performance in terms of xylose recovery. The result point out that the maximum xylose yield of 30.7 g per 100 g of dry kenaf was attained from 2% (v/v) HNO3 at 130 °C for 60 min. The detoxified hydrolysate was incorporated as the primary carbon source for subsequent fermentation by recombinant Escherichia coli and the performance of strain on five different semi-synthetic media on xylitol production were evaluated herein. Among these media, batch cultivation in a basal salt medium (BSM) afforded the highest xylitol yield of 0.35 g/g based on xylose consumption, which corresponded to 92.8% substrate utilization after 38 h. Subsequently, fermentation by E. coli in the xylose-based kenaf hydrolysate supplemented with BSM resulting in 6.8 g/L xylitol which corresponding to xylitol yield of 0.38 g/g. These findings suggested that the use of kenaf as the fermentation feedstock could be advantageous for the development of sustainable xylitol production.

    Radiotherapy (RT) treats cancer effectively with high doses of ionizing radiation (IR) to killing cancer cells and shrinking tumors while bearing the risk of developing different side effects, including secondary cancer, which is most concerning for long-term health consequences. Genomic instability (GI) is a characteristic of most cancer cells, and IR-induced GI can manifest as delayed homologous recombination (HR). Radioadaptive response (RAR) is capable of reducing genotoxicity, cell transformation, mutation, and carcinogenesis, but the rational evidence describing its contributions to the reduction of radiation risk, in particular, carcinogenesis, remains fragmented. In this work, to investigate the impact of RAR on high-dose, IR-induced GI measured as delayed HR, the frequency of recombinant cells was comparatively studied under RAR-inducible and -uninducible conditions in the nucleated cells in hematopoietic tissues (bone marrow and spleen) using the Rosa26 Direct Repeat-green fluorescent protein (RaDR-GFP) homozygote mice. Results demonstrated that the frequency of recombinant cells was significantly lower in hematopoietic tissues under RAR-inducible condition. These findings suggest that reduction in delayed HR may be at least a part of the mechanisms underlying decreased carcinogenesis by RAR, and application of RAR would contribute to a more rigorous and scientifically grounded system of radiation protection in RT.

    Background: Epidemiological and experimental studies have extensively indicated that chronic subclinical systemic inflammation (CSSI) and oxidative stress are risk factors for several chronic diseases, including cancer, arthritis, type 2 diabetes, and cardiovascular and neurodegenerative diseases. This study examined the protective effect of stingless bee honey (SBH) supplementation against lipopolysaccharide (LPS)-induced CSSI, pointing to the possible involvement of NF-κB, p38 MAPK and Nrf2 signaling.

    Methods: CSSI was induced in male Sprague Dawley rats by intraperitoneal injection of LPS three times per week for 28 days, and SBH (4.6 and 9.3 g/kg/day) was supplemented for 30 days.

    Results: LPS-induced rats showed significant leukocytosis, and elevated serum levels of CRP, TNF-α, IL-1β, IL-6, IL-8, MCP-1, malondialdehyde (MDA) and 8-hydroxy-2'-deoxyguanosine (8-OHdG), accompanied with diminished antioxidants. Treatment with SBH significantly ameliorated inflammatory markers, MDA and 8-OHdG, and enhanced antioxidants in LPS-induced rats. In addition, SBH decreased NF-κB p65 and p38 MAPK, and increased Nrf2 expression in the liver, kidney, heart and lung of LPS-induced rats. Furthermore, SBH prevented LPS-induced histological and functional alterations in the liver, kidney, heart and lung of rats.

    Conclusion: SBH has a substantial protective role against LPS-induced CSSI in rats mediated via amelioration of inflammation, oxidative stress and NF-κB, p38 MAPK and Nrf2 signaling.

    In the last three decades, Clostridium difficile infection (CDI) has increased in incidence and severity in many countries worldwide. The increase in CDI incidence has been particularly apparent among surgical patients. Therefore, prevention of CDI and optimization of management in the surgical patient are paramount. An international multidisciplinary panel of experts from the World Society of Emergency Surgery (WSES) updated its guidelines for management of CDI in surgical patients according to the most recent available literature. The update includes recent changes introduced in the management of this infection.

    PURPOSE: Manual segmentation is sensitive to operator bias, while semiautomatic random walks segmentation offers an intuitive approach to understand the user knowledge at the expense of large amount of user input. In this paper, we propose a novel random walks seed auto-generation (SAGE) hybrid model that is robust to interobserver error and intensive user intervention.

    METHODS: Knee image is first oversegmented to produce homogeneous superpixels. Then, a ranking model is developed to rank the superpixels according to their affinities to standard priors, wherein background superpixels would have lower ranking values. Finally, seed labels are generated on the background superpixel using Fuzzy C-Means method.

    RESULTS: SAGE has achieved better interobserver DSCs of 0.94 ± 0.029 and 0.93 ± 0.035 in healthy and OA knee segmentation, respectively. Good segmentation performance has been reported in femoral (Healthy: 0.94 ± 0.036 and OA: 0.93 ± 0.034), tibial (Healthy: 0.91 ± 0.079 and OA: 0.88 ± 0.095) and patellar (Healthy: 0.88 ± 0.10 and OA: 0.84 ± 0.094) cartilage segmentation. Besides, SAGE has demonstrated greater mean readers' time of 80 ± 19 s and 80 ± 27 s in healthy and OA knee segmentation, respectively.

    CONCLUSIONS: SAGE enhances the efficiency of segmentation process and attains satisfactory segmentation performance compared to manual and random walks segmentation. Future works should validate SAGE on progressive image data cohort using OA biomarkers.

    PURPOSE: Mercury is widely used in medical and healthcare facilities as dental amalgam, mercury-added medical devices, thiomersal-containing vaccines, laboratory analysis and for other general applications despite the hazards. Various agencies consistently promote mercury-free medical facilities through mercury-free alternatives and better management practices, which are in line with the Minamata Convention on Mercury that aims to protect human health and environment from anthropogenic mercury release. The paper aims to discuss these issues.

    DESIGN/METHODOLOGY/APPROACH: The authors conducted a gap analysis on recommended practices gathered from the literature and current practices gathered through semi-structured interviews with Malaysian medical personnel. A life cycle approach was adopted covering mercury use: input, storage, handling, accident, waste disposal and governance phases.

    FINDINGS: The authors found that there are significant gaps between recommended and current mercury management practices. Analysis indicates improper mercury management as the main contributor to these gaps. The authors found from recommended practices that core components needing improvement include: mercury management action plan, mercury use identification team, purchasing policy, proper guidelines and monitoring systems.

    PRACTICAL IMPLICATIONS: This study helps us to understand mercury management practices and suggests essential steps to establish a mercury-free medical facility.

    ORIGINALITY/VALUE: This study explored the gaps between recommended and current mercury management practices in a medical facility and contributes to the Minamata Convention on Mercury aspirations.

    PURPOSE: The purpose of this paper is to improve the Siloam Hospitals' (SHs) patient satisfaction index (PSI) and overcome Indonesia's geographical barriers.

    DESIGN/METHODOLOGY/APPROACH: The topic was selected for reasons guided by the Institute of Healthcare Improvement virtual breakthrough series collaborative (VBSC). Subject matter experts came from existing global quality development in collaboration with sales and marketing, and talent management agencies/departments. Patient satisfaction (PS) was measured using the SH Customer Feedback Form. Data were analysed using Friedman's test.

    FINDINGS: The in-patient (IP) department PSI repeated measures comparison during VBSC, performed using Friedman's test, showed a statistically significant increase in the PSI, χ2 = 44.00, p<0.001. Post hoc analysis with Wilcoxon signed-rank test was conducted with a Bonferroni correction applied, which resulted in a significant increase between the baseline and action phases ( Z=3.317, p=0.003) between the baseline and continuous improvement phases ( Z=6.633, p<0.001), and between the action and continuous improvement phases ( Z=3.317, p=0.003), suggesting that IP PSI was continuously increasing during all VBSC phases. Like IP PSI, the out-patient department PSI was also continuously increasing during all VBSC phases.

    RESEARCH LIMITATIONS/IMPLICATIONS: The VBSC was not implemented using a control group. Factors other than the VBSC may have contributed to increased PS.

    PRACTICAL IMPLICATIONS: The VBSC was conducted using virtual telecommunication. Although conventional breakthrough series might result in better cohesiveness and commitment, Indonesian geographical barriers forced an alternative strategy, which is much more cost-effective.

    ORIGINALITY/VALUE: The VBSC, designed to improve PS, has never been implemented in any Indonesian private hospital group. Other hospital groups might also appreciate knowing about the VBSC to improve their PSI.

    Total polar compounds (TPC) and free fatty acids (FFA) are important indicators in evaluating the quality of frying oil. Conventional methods to determine TPC and FFA are often time consuming, involved laboratory analyses which required skilled personnel and used substantial amount of harmful solvent. In this study, dielectric spectroscopy technique was used to investigate the relation between dielectric property of refined, bleached and deodorized palm olein (RBDPO) during deep frying with TPC and FFA. In total, 150 batches of French fries were intermittently fried at 185 ± 5 °C for 7 hr a day over 5 consecutive days. A total of 30 frying oil samples were collected. The dielectric property of frying oil samples were measured using impedance analyzer with frequencies ranging from 100 Hz to 10 MHz. The TPC of frying oil samples were measured with a Testo 270, while the FFA analysis was done using Malaysian Palm Oil Board (MPOB) test method. Results showed that dielectric constant, TPC and FFA of RBDPO increased as the frying time increased. Dielectric constant increased from 3.09 to 3.17, while TPC and FFA increased from 9.96 to 19.52 and from 0.08% to 0.36%, respectively. Partial least square (PLS) analysis produced good prediction of TPC and FFA with the application of genetic algorithm (GA). Model developed for prediction of TPC and FFA yielded highly significant correlation with R2 of 0.91 and 0.95, respectively and both had root mean square error in cross-validation (RMSECV) of 1.06%. This study demonstrates the potential of dielectric spectroscopy in monitoring palm olein degradation during frying. PRACTICAL APPLICATION: The application of dielectric spectroscopy to detect degradation of palm olein during frying was studied. The dielectric property of palm olein during frying has successfully correlated with TPC and FFA. The model developed in this study could be used for the development of a sensing system for palm olein degradation monitoring.

    The transition from monolayer to multilayer adsorption at the air-water interface in the presence of multivalent counterions has been demonstrated for a limited range of anionic surfactants which exhibit increased tolerance to precipitation in the presence of multivalent counterions. Understanding the role of molecular structure in determining the transition to surface ordering is an important aspect of the phenomenon. The focus of the paper is on the alkyl ester sulfonate, AES, surfactants; a promising group of anionic surfactants, with the potential for improved performance and biocompatibility. Neutron reflectivity measurements were made in aqueous solution and in the presence of NaCl, CaCl2, MgCl2 and AlCl3, for a range of alkyl ester sulfonate surfactants, in which the headgroup and alkyl chain geometries were manipulated. In the regions of monolayer adsorption changing the AES headgroup and alkyl chain geometries results in an increased saturation adsorption and in a more gradual decrease in the adsorption at low concentrations, consistent with a greater adsorption efficiency. Changing the AES headgroup and alkyl chain geometries also results in changes in the transition from monolayer adsorption to more ordered surface structures with the addition of AlCl3 and mixed multivalent electrolytes. A more limited surface layering is observed for the ethyl ester sulfonate, EES, with a C14 alkyl chain. Replacing the C14 alkyl chain with a C18 isostearic chain results in only monolayer adsorption. The results demonstrate the role and importance of the surfactant molecular structure in determining the nature of the surface adsorption in the presence of different electrolytes, and in the tendency to form extended surface multilayer structures.

    BACKGROUND: Fetal subdural haematoma (SDH) is associated with poor prognosis.

    OBJECTIVE: The conflicting evidence from the literature presents a challenge in prenatal counselling. We present a case study and systematic review of the literature for the management and outcome of fetal SDH.

    METHODS: Systematic search of electronic database.

    RESULTS: A total 45 cases were extracted from 39 papers. Prenatal ultrasonographic features were intracranial echogenicity (42%), lateral ventriculomegaly (38%), presence of an intracranial mass (31%), macrocephaly (24%), midline deviation of cerebral falx (20%), and intracranial fluid collection (11%). Further secondary features were noted including reversed diastolic flow in the middle cerebral artery (11%), echogenic bowel (4%), hydrops fetalis (2%), and elevated middle cerebral artery peak systolic velocity (2%) (all highly likely to be associated with fetal anaemia). The rates of termination of pregnancy, stillbirth, and neonatal death were 18% (8/45), 16% (7/45), and 11% (5/45), respectively. Overall, therefore, the fetal and perinatal mortality was 32% (12/37). Amongst the 24 survivors with available neurological outcome, 42% (10/24) and 58% (14/24) had abnormal and normal neurological outcome, respectively. Underlying aetiology of fetal SDH was not identified in 47% (21/45). Fetal SDH with an identifiable underlying aetiology was the only factor associated with a higher chance of normal neurological outcome when compared to fetal SDH without a detectable cause (78.5 vs. 21.4%, p = 0.035).

    CONCLUSIONS: Stillbirth and neonatal death occurred in a significant proportion of fetal SDH. 58% of survivors had normal neurological outcome, and better prognosis was seen in SDH with identifiable underlying aetiology.

    PURPOSE: This study aimed to assess the degree of acceptance of problem-based learning (PBL) among phase one medical students and its association with academic self-concept (ASC) and internal locus of control (ILOC).

    METHODS: A 5-point Likert scale valid and reliable questionnaire assessing the attitude towards PBL, ASC, and ILOC was given to phase one medical students at MAHSA University. Data were analysed using IBM SPSS ver. 22.0 (IBM Corp., Armonk, USA).

    RESULTS: Out of 255 participants, there were 84 males and 171 females, 175 Malaysians and 80 non-Malaysians. The results showed an overall acceptance of PBL with a mean of 3.7±0.07, ASC of 3.5±0.05 and ILOC of 2.9±0.05. Females showed a higher significant acceptance of PBL, ASC, and ILOC as compared with males. There was no difference between Malaysians and non-Malaysians in any of the variables measured. Simple regression analysis revealed a significant predictive effect of acceptance of PBL on ASC and ILOC (r=0.44 and r=0.88, respectively).

    CONCLUSION: The higher the acceptance of PBL among students, the higher is the ASC and ILOC. This reflects the importance of PBL as a teaching method as well as the importance of increasing the level of appreciation of PBL amongst students.

    BACKGROUND:: Trigger finger release utilizing wide-awake local anesthesia no tourniquet (WALANT) usage in extremity surgery is not widely used in our setting due to the possibility of necrosis. Usage of a tourniquet is generally acceptable for providing surgical field hemostasis. We evaluate hemostasis score, surgical field visibility, onset and duration of anesthesia, pain score, and the duration of surgery and potential side effects of WALANT.

    METHODS:: Eighty-six patients scheduled for trigger finger release between July 2016 and December 2017 were randomized into a control group (1% lignocaine and 8.4% sodium bicarbonate with arm tourniquet; given 10 min prior to procedure) and an intervention group (1% lignocaine, 1:100,000 of adrenaline and 8.4% sodium bicarbonate; given 30 min prior to procedure), with a total of 4 ml of solution injected around the A1 pulley. The onset of anesthesia and pain score upon injection of the first 1 ml were recorded. After the procedure, the surgeon rated for the hemostasis score (1-10: 1 as no bleeding and 10 being profuse bleeding). Duration of surgery and return of sensation were recorded.

    RESULTS:: Hemostasis score was grouped into visibility score as 1-3: good, 4-6: moderate, and 7-10: poor. The intervention group (with adrenaline) had a 74% of good surgical field visibility compared to 44% from the controlled group (without adrenaline; p < 0.05). Duration of anesthesia was longer in the intervention group (with adrenaline), with a 2.77-h difference.

    CONCLUSION:: WALANT provides excellent surgical field visibility and is safe and on par with conventional methods but without the usage of a tourniquet and its associated discomfort.

    INTRODUCTION: Prevalence estimates depend largely on the nature of the question asked to define the presence of the health condition, and the literature on the population burden of tinnitus and hearing difficulties is no different in this respect. The lack of standardized questions for data collection limits comparison across studies and across countries. The purpose of this short Technical Note is to report the first attempt to establish a set of standard questions developed for use in population-based surveys, and their adaptation and translation from English into 11 European languages.

    METHODS: Four questions and their corresponding response options were adapted from existing population-based surveys to assess tinnitus prevalence, tinnitus symptom severity, use of healthcare resources for tinnitus and hearing difficulty. The translated versions (Bulgarian, French, German, Greek, Italian, Latvian, Polish, Portuguese, Romanian, Russian, and Spanish) were generated using recognized methods to achieve a "world-for-world" translation.

    RESULTS: Translated versions were produced with acceptable functional equivalence to the original English-language version, as judged by a small panel of bilingual speakers who participated in the online field testing.

    CONCLUSION: This work is the first of its kind to promote multi-national standardization by creating a set of tools that can readily be used across countries. These are currently being used in a European-wide study of tinnitus prevalence, and have wider application across English- and Spanish speaking countries including the Americas and Oceania.

    ETHNOPHARMACOLOGICAL RELEVANCE: Medicinal plants have been used for ages by indigenous communities around the world to help humankind sustain its health. Graviola (Annona muricata), also called soursop, is a member of the Annonaceae family and is an evergreen plant that is generally distributed in tropical and subtropical areas of the world. Graviola tree has a long history of traditional use due to its therapeutic potential including anti-inflammatory, antimicrobial, antioxidant, insecticide and cytotoxic to tumor cells.

    AIM OF THE STUDY: This study aimed to investigate the in vitro antiproliferative effects and apoptotic events of the ionic liquid extract of Graviola fruit (IL-GFE) on MCF-7 breast cancer cells and their cytokinetics behaviour to observe their potential as a therapeutic alternative in cancer treatment.

    MATERIALS AND METHODS: The cell viability assay of the extract was measured using tetrazolium bromide (MTT assay) to observe the effects of Graviola fruit extract. Then the cytokinetics behaviour of MCF-7 cells treated with IL-GFE is observed by plotting the growth curve of the cells. Additionally, the cell cycle distribution and apoptosis mechanism of IL-GFE action on MCF-7 cancer cells were observed by flow cytometry.

    RESULTS: IL-GFE exhibited anti-proliferative activity on MCF-7 with the IC50 value of 4.75 μg/mL, compared to Taxol with an IC50 value of 0.99 μg/mL. IL- GFE also reduced the number of cell generations from 3.71 to 1.67 generations compared to 2.18 generations when treated with Taxol. Furthermore, the anti-proliferative activities were verified when the growth rate was decreased dynamically from 0.0077 h to 1 to 0.0035 h-1. Observation of the IL-GFE-treated MCF-7 under microscope demonstrated detachment of cells and loss of density. The growth inhibition of the cells by extracts was associated with cell cycle arrest at the G0/G1 phase, and phosphatidylserine externalisation confirms the anti-proliferation through apoptosis.

    CONCLUSIONS: ionic liquid Graviola fruit extract affect the cytokinetics behaviour of MCF-7 cells by reducing cell viability, induce apoptosis and cell cycle arrest at the G0/G1 phase.

    AIM: The aim of this narrative review was to explore the potential contributions of CAM to reduce antibiotic use.

    METHODS: We searched PubMed, Embase, and Cochrane Database of Systematic Reviews with a specific, limited set of search terms and collected input from a group of expert CAM researchers to answer the question: What is known about the contribution of CAM health and health promotion concepts, infection prevention, and infection treatment strategies to reduce antibiotic use? Results. The worldview-related CAM health concepts enable health promotion oriented infection prevention and treatment aimed at strengthening or supporting the self-regulating ability of the human organism to cope with diseases. There is some evidence that the CAM concepts of health (promotion) are in agreement with current conceptualization of health and that doctors who practice both CAM and conventional medicine prescribe less antibiotics, although selection bias of the presented studies cannot be ruled out. There is some evidence that prevention and some treatment strategies are effective and safe. Many CAM treatment strategies are promising but overall lack high quality evidence.

    CONCLUSIONS: CAM prevention and treatment strategies may contribute to reducing antibiotic use, but more rigorous research is necessary to provide high quality evidence of (cost-)effectiveness.
