    Background/Aims: The clinical practice pattern of polypectomy is not well-investigated in Asian countries. We aimed to survey Asian endoscopists about their preferred polypectomy techniques for given conditions and images of polyps.

    Methods: A survey was performed using questionnaires composed of two parts: a scenario-based questionnaire using scenarios of polyps, which were adopted from the European Society of Gastrointestinal Endoscopy guidelines, and an image-based questionnaire using provided endoscopic images of polyps.

    Results: A total of 154 endoscopists participated in this survey. The most preferred resection techniques for diminutive (≤5 mm), small (6-9 mm), and benign-looking intermediate (10-19 mm) nonpedunculated polyps were cold forceps polypectomy, hot snare polypectomy, and endoscopic mucosal resection (EMR), respectively, in both the scenario- and image-based questionnaires. For benign-looking large (≥20 mm) nonpedunculated polyps, EMR and endoscopic submucosal dissection (ESD) were preferred in the scenario- and image-based surveys, respectively. In case of malignant nonpedunculated polyps, EMR and ESD were preferred for intermediate-sized and large lesions, respectively, according to the scenario-based survey. However, ESD was preferred in both intermediate-sized and large malignant nonpedunculated polyps according to the image-based survey. Trainee endoscopists, endoscopists working in referral centers, and endoscopists in the colorectal cancer-prevalent countries were independently associated with preference of cold snare polypectomy for removing small polyps.

    Conclusions: The polypectomy practice patterns of Asian endoscopists vary, and cold snare polypectomy was not the most preferred resection method for polyps <10 mm in size, in contrast to recent guidelines.

    Nanostructured photocatalysts commonly offered opportunities to solve issues scrutinized with the environmental challenges caused by steep population growth and rapid urbanization. This photocatalyst is a controllable characteristic, which can provide humans with a clean and sustainable ecosystem. Over the last decades, one of the current thriving research focuses on visible-light-driven CeO2-based photocatalysts due to their superior characteristics, including unique fluorite-type structure, rigid framework, and facile reducing oxidizing properties of cerium's tetravalent (Ce4+) and trivalent (Ce3+) valence states. Notwithstanding, owing to its inherent wide energy gap, the solar energy utilization efficiency is low, which limits its application in wastewater treatment. Numerous modifications of CeO2 have been employed to enhance photodegradation performances, such as metals and non-metals doping, adding support materials, and coupling with another semiconductor. Besides, all these doping will form a different heterojunction and show a different way of electron-hole migration. Compared to conventional heterojunction, advanced heterojunction types such as p-n heterojunction, Z-scheme, Schottky junction, and surface plasmon resonance effect exhibit superior performance for degradation owing to their excellent charge carrier separation, and the reaction occurs at a relatively higher redox potential. This review attends to providing deep insights on heterojunction mechanisms and the latest progress on photodegradation of various contaminants in wastewater using CeO2-based photocatalysts. Hence, making the CeO2 photocatalyst more foresee and promising to further development and research.

    With the tremendous development of the economy and industry, the pollution of water is becoming more serious due to the excessive chemical wastes that need to remove thru reduction or oxidation reactions. Simultaneous removal of dual pollutants via photocatalytic redox reaction has been tremendously explored in the last five years due to effective decontamination of pollutants compared to a single pollutants system. In a photocatalysis mechanism, the holes in the valence band can remarkably promote the oxidation of a pollutant. At the same time, photoexcited electrons are also consumed for the reduction reaction. The synergistic between the reduction and oxidation inhibits the recombination of electron-hole pairs extending their lifetime. In this review, the binary pollutants that selectively removed via photocatalysis reduction or oxidation are classified according to heavy metal-organic pollutant (HM/OP), heavy metal-heavy metal (HM/HM) and organic-organic pollutants (OP/OP). The intrinsic between the pollutants was explained in three different mechanisms including inhibition of electron-hole recombination, ligand to metal charge transfer and electrostatic attraction. Several strategies for the enhancement of this treatment method which are designation of catalysts, pH of mixed pollutants and addition of additive were discussed. This review offers a recent perspective on the development of photocatalysis system for industrial applications.

    INTRODUCTION: Malaysia has a high rate of smoking prevalence and the figure is increasing. Although there has been many local and regional studies on the prevalence and symptomatology of chronic obstructive pulmonary disease patients, data is lacking on the degree of compliance to national management guidelines in the treatment of chronic obstructive pulmonary disease.
    METHODS: 86 patients who attended the respiratory outpatient clinic of the Hospital Universiti Kebangsaan Malaysia were enrolled into a prospective, observational study.
    RESULTS: 88 percent of the patients were male and the majority was ethnically Chinese (65 percent). The majority of patients were in the moderate to very severe categories, with a mean FEV1 of 0.97 +/- 0.56 L/sec and predicted mean FEV1 percentage of 43.1 +/- 21.3 percent. 58 percent of the patients were on long-acting beta-agonist, 65 percent were on inhaled steroids, and only 16 percent were on scheduled pulmonary rehabilitation.
    CONCLUSION: The low uptake rate for long-acting beta-agonist and pulmonary rehabilitation could be attributed to several factors. Financial cost, the need for strict compliance to a structured rehabilitation regime, lack of significant social support and clear up-to-date guidelines are possible reasons.

    CONTEXT: Menhaden fish oil (FO) is widely recognized for inhibiting neuroinflammatory responses and preserving brain function. Nevertheless, the mechanisms of FO influencing brain cognitive function in diabetic states remain unclear.

    OBJECTIVE: This study examines the potential role of FO in suppressing LPS-induced neuroinflammation and cognitive impairment in diabetic animals (DA).

    MATERIALS AND METHODS: Thirty male Wistar rats were divided into 5 groups: i) DA received LPS induction (DA-LPS); ii) DA received LPS induction and 1 g/kg FO (DA-LPS-1FO); iii) DA received LPS induction and 3 g/kg FO (DA-LPS-3FO); iv) animals received normal saline and 3 g/kg FO (NS-3FO) and v) control animals received normal saline (CTRL). Y-maze test was used to measure cognitive performance, while brain samples were collected for inflammatory markers and morphological analysis.

    RESULTS: DA received LPS induction, and 1 or 3 g/kg FO significantly inhibited hyperglycaemia and brain inflammation, as evidenced by lowered levels of pro-inflammatory mediators. Additionally, both DA-LPS-1FO and DA-LPS-3FO groups exhibited a notable reduction in neuronal damage and glial cell migration compared to the other groups. These results were correlated with the increasing number of entries and time spent in the novel arm of the Y-maze test.

    DISCUSSION AND CONCLUSION: This study indicates that supplementation of menhaden FO inhibits the LPS signaling pathway and protects against neuroinflammation, consequently maintaining cognitive performance in diabetic animals. Thus, the current study suggested that fish oil may be effective as a supporting therapy option for diabetes to avoid diabetes-cognitive impairment.

    BACKGROUND: Tumor lysis syndrome (TLS) is an oncological emergency associated with hematological malignancies or highly proliferative solid tumors, commonly after chemotherapy. It is rarely associated with transient abnormal myelopoiesis.

    OBSERVATION: We report a rare case of a neonate with transient abnormal myelopoiesis and tumor lysis syndrome, complicated with concomitant heart failure due to an underlying atrioventricular septal defect. Hyperhydration was contraindicated due to heart failure. The patient was managed conservatively with full recovery.

    CONCLUSION: Tumor lysis syndrome should be suspected in neonates with transient abnormal myelopoiesis with electrolyte abnormalities. Treatment options should be considered carefully for their risks and benefits.

    The aim of this study was to assess the bone mineral density (BMD) of premenopausal patients with systemic lupus erythematosus (SLE) on corticosteroids (CS) and to determine the influence of CS and other risk factors on BMD. A total of 98 premenopausal patients with SLE were recruited from outpatient clinics in two teaching hospitals. Risk factors for osteoporosis were determined, and BMD was measured using dual-energy x-ray absorptiometry. The mean age of the patients was 30.05 +/- 7.54 years. The mean dose of prednisolone at time of BMD measurement was 18.38 +/- 10.85 mg daily. Median duration of CS use was 2.5 years (range 0-20). Median cumulative dose of CS was 9.04 g (range 0.28-890.0). Six patients (6.1%) had osteoporosis, 41 (41.9%) had osteopenia and 51 (52.0%) had normal BMD. Lumbar spine T score correlated with cumulative CS dose (P = 0.019). Duration of CS intake correlated with femoral neck T score (P = 0.04) and trochanter T score (P = 0.008). There was no correlation between BMD and race, SLE Disease Activity Index score, smoking and self-reported calcium intake or exercise. Only 52% of these patients had normal BMD. The duration and cumulative dose of CS intake was significantly correlated to BMD, but not the other commonly assessed risk factors. These findings suggest that premenopausal patients with SLE on CS should have their BMD measured at regular intervals to fully assess their osteoporosis risk.

    BACKGROUND: The International Classification of Functioning, Disability and Health (ICF) serves as a framework for defining and categorizing health and functioning. ICF could be used to classify research outcomes in a systematic manner.

    AIM: The aim of this study was to classify the primary outcomes used in Cochrane Systematic Reviews (CSRs) into the ICF domains of functioning; to describe the differences in primary outcomes in reviews related to rehabilitation intervention and non-rehabilitation intervention; and to describe the trend of outcome selections according year of publication.

    DESIGN: Methodological paper.

    POPULATION: Adult stroke population.

    METHODS: We analyzed the primary outcomes used in the CSRs published by the Cochrane Stroke Review Group up to December 2017. The primary outcomes were extracted and classified into the ICF domains of functioning (body functions, body structures and activity and participation).

    RESULTS: One hundred and seventy-four papers with 216 primary outcomes were included in this analysis. Less than half (102/216, 47.2%) of the outcomes could be classified into the ICF domains of functioning. For the outcomes that could be classified into the ICF domains, the majority (72/102, 70.5%) were in the activity and participation domain, followed by body functions (26/102, 25.5%) and body structures (4/102, 4.0%). Of the outcomes that could not be classified into the ICF domains (N.=114), death (81/114, 71.1%) and recurrent stroke (21/114,18.4%) formed the majority of the outcome. There were 75 CSRs on rehabilitation related interventions; the majority of the outcomes (75/97, 77.3%) used in rehabilitation related CSRs could be classified into the ICF framework with more than half (49/75, 65.3%) in the activity and participation domain.

    CONCLUSIONS: The majority of the primary outcomes selected by the Cochrane Stroke Review Group in their CSRs could not be classified into the ICF domains of functioning. Death and recurrence of vascular events remains the major outcome of interest. In rehabilitation related interventions, activity and participation domain is the functioning domain most commonly used.

    CLINICAL REHABILITATION IMPACT: The systematic use of patients-centered ICF-based outcomes in CSRs could help the application of evidence in clinical decision making.

    Fibrous silica-titania (FST) catalysts were synthesized by microemulsion followed by silica seed-crystal crystallization methods under various molar ratios of toluene to water (T/W). The catalysts were characterized by XRD, UV-DRS, FESEM, TEM, AFM, N2 adsorption-desorption, FTIR, and ESR. The results revealed that altering the T/W ratio affected the growth of the silica and titania and led to different size, fiber density, silica-titania structure, and number of hydroxyl groups, as well as oxygen vacancies in the FSTs, which altered their behavior toward subsequent application. Photodegradation of ibuprofen (IBP) are in the following order: FST(6:1) (90%) > FST(5:1) (84%) > FST(7:1) (79%) > commercial TiO2 (67%). A kinetics study using Langmuir-Hinshelwood model illustrated that the photodegradation followed the pseudo-first-order and adsorption was the rate-limiting step. Optimization by response surface methodology (RSM) showed that the pH, initial concentration, and catalyst dosage were the remarkable parameters in photodegradation of IBP. The FST (6:1) maintained its photocatalytic activities for up to five cycles reaction without serious catalyst deactivation, and was also able to degrade other endocrine-disrupting chemicals, indicating its potential use for the treatment of those chemicals in wastewater.

    Background/Aims: As the number of colonoscopies and polypectomies performed continues to increase in many Asian countries, there is a great demand for surveillance colonoscopy. The aim of this study was to investigate the adherence to postpolypectomy surveillance guidelines among physicians in Asia.

    Methods: A survey study was performed in seven Asian countries. An email invitation with a link to the survey was sent to participants who were asked to complete the questionnaire consisting of eight clinical scenarios.

    Results: Of the 137 doctors invited, 123 (89.8%) provided valid responses. Approximately 50% of the participants adhered to the guidelines regardless of the risk of adenoma, except in the case of tubulovillous adenoma ≥10 mm combined with high-grade dysplasia, in which 35% of the participants adhered to the guidelines. The participants were stratified according to the number of colonoscopies performed: ≥20 colonoscopies per month (high volume group) and <20 colonoscopies per month (low volume group). Higher adherence to the postpolypectomy surveillance guidelines was evident in the high volume group (60%) than in the low volume group (25%). The reasons for nonadherence included concern of missed polyps (59%), the low cost of colonoscopy (26%), concern of incomplete resection (25%), and concern of medical liability (15%).

    Conclusions: A discrepancy between clinical practice and surveillance guidelines among physicians in Asia was found. Physicians in the low volume group frequently did not adhere to the guidelines, suggesting a need for continuing education and appropriate control. Concerns regarding the quality of colonoscopy and complete polypectomy were the main reasons for nonadherence.

    Ternary CuO/AgO/FSZr photocatalysts were fabricated via the hydrothermal and electrochemical methods with three different CuO loading (1, 3 and 5 wt%), indicated as 1CuO/AgO/FSZr, 3CuO/AgO/FSZr and 5CuO/AgO/FSZr. The photocatalytic reaction was tested towards simultaneous chromium (VI) photoreduction and p-cresol photooxidation and the performance in order as follow: 3CuO/AgO/FSZr > 5CuO/AgO/FSZr > 1CuO/AgO/FSZr > AgO/FSZr > FSZr. CuO/AgO/FSZr photocatalysts showed an improvement in photocatalytic activity compared to AgO/FSZr and FSZr due to the reduction potential of chromium (VI) aligned closer to the conduction band of CuO and provided abundant free active electrons (e-) and holes (h+) with efficient transportation and migration. Interestingly, the 3CuO/AgO/FSZr was established as the best photocatalyst with 98% reduction of chromium (VI) and 83% oxidation of p-cresol simultaneously, owing to its strong corporation between the metal oxides and support and higher total pore volume. The Langmuir-Hinshelwood model were employed for kinetics which followed the pseudo-first-order kinetics model well. Based on the simultaneous photocatalytic mechanism, chromium (VI) and p-cresol were directly reduced and oxidized by e- and h+, respectively. The response surface methodology (RSM) discovered that the quadratic term initial concentration of chromium (VI) is the main significant factor in photocatalytic performance. The optimum parameters for simultaneous photoredox of chromium (VI) and p-cresol predicted from RSM are 9.6 mg L-1 of chromium (VI) concentration, 9.8 mg L-1 of p-cresol concentration and 0.32 g L-1 of catalyst dosage. Under these conditions the error between the predicted and experimental values is only 3.7%. The 3CuO/AgO/FSZr sustained the photocatalytic performance after reused for five cycles and could oxidized various organic pollutants as well as reduced chromium (VI) simultaneously.

    Background: In a previous study, we demonstrated that the accumulation of parenting stress during prolonged school closures and restrictions on daily activities due to the COVID-19 pandemic in Japan indicates the need for mental health intervention for parents at higher risk of parenting stress. However, few studies have focused on parenting stress in other Asian countries, although they have experienced higher numbers of infections. The aim of the present study was to investigate whether parenting stress among caregivers increased across Asia due to school closures and restrictions on activities during the COVID-19 pandemic and to examine whether there were any country-specific, cross-country, or cross-regional risk factors for increased parenting stress. Methods: We conducted an online survey immediately after the number of new cases in India significantly increased (September-November 2020). We measured parenting stress, anxiety, and fear associated with the COVID-19 crisis, as evaluated by the Parenting Stress Index, Short-Form (PSI-SF), and the Coronavirus Anxiety Scale (CAS), across three Asian countries-India (n = 142), Malaysia (n = 69), and Japan (n = 182)-in addition to the United States (n = 203). We also investigated whether respondents had adverse childhood experiences (ACE) as a risk factor for parenting stress. Results: For all countries, we found significant increases in participants' current parenting stress levels, compared to what they recalled regarding their lives before COVID-19-related restrictions and school closures were enacted. Textual analysis qualitatively identified common terms related to parenting stress across all countries. We also found a statistical model that indicated ACE in parents was a critical risk factor for higher parenting stress via increasing anxiety and fear related to the pandemic. Conclusion: These results indicate the need to improve the mental health of caregivers who are at risk for higher levels of parenting stress during the COVID-19 pandemic in Asian countries as well as Western countries. These results indicate that there is a need to improve the mental health of caregivers who are at risk for higher levels of parenting stress during the COVID-19 pandemic globally.

    Study design: Global mapping project of ISCoS for traumatic spinal cord injury (T-SCI) highlighted paucity of data from low and middle income countries (LMICs). Recognizing this gap, IDAPP study of one year duration was proposed as the first step to develop an International SCI database.

    Objectives: Primary objective was to assess database variables, processes involved and web platform for their suitability with a view to provide guidance for a large scale global project. Secondary objective was to capture demographic and selected injury/safety data on patients with T-SCI with a view to formulate prevention strategies.

    Setting: Nine centers from Asia.

    Methods: All patients with T-SCI admitted for first time were included. International SCI Core Data Set and especially compiled Minimal Safety Data Set were used as data elements. Questionnaire was used for feedback from centers.

    Results: Results showed relevance and appropriateness of processes, data variables and web platform of the study. Ease of entering and retrieval of data from web platform was confirmed. Cost of one year IDAPP study was USD 7780. 975 patients were enrolled. 790 (81%) were males. High falls (n = 513, 52%) as a cause and complete injuries (n = 547, 56%) were more common. There was a higher percentage of thoracic and lumbar injuries (n = 516, 53%).

    Conclusions: The study confirms that establishing the SCI database is possible using the variables, processes and web platform of the pilot study. It also provides a low cost solution. Expansion to other centers/regions and including non-traumatic SCI would be the next step forward.

    BACKGROUND Plasma cell leukemia (PCL) is an aggressive form of plasma cell neoplasm. We report the first case of primary PCL successfully treated with upfront novel agents consisting of Venetoclax and daratumumab in combination with intensive chemotherapy and allogeneic transplantation. CASE REPORT A 59-year-old woman presented with epistaxis, gum bleeding, and blurred vision. On examination, she appeared pale, with multiple petechiae and hepatomegaly. Fundoscopy revealed retinal hemorrhages. Laboratory investigations revealed bicytopenia and leukocytosis, with mild coagulopathy and hypofibrinogenemia. Elevated globulin and calcium levels were also observed. Serum protein electrophoresis demonstrated IgG lambda paraproteinemia, with a serum-free light chain kappa-to-lambda ratio of 0.074. A skeletal survey revealed the presence of lytic lesions. Bone marrow investigations confirmed the presence of lambda-light-chain-restricted clonal plasma cells. FISH detected t(11;14) and 17p13.1 deletion. Therefore, a final diagnosis of primary PCL was made. The patient received 1 cycle of bortezomib, cyclophosphamide, and dexamethasone (VCD) and 5 cycles of Venetoclax-VCD, followed by an unsuccessful stem cell mobilization. One cycle of daratumumab in combination with bortezomib, lenalidomide, and dexamethasone (VRD) was then given. The patient achieved complete remission. She underwent allogeneic stem cell transplantation of an HLA-matched sibling donor. Post-transplant marrow assessment showed disease remission and absence of t(11;14) and 17p deletions. She was administered pamidronate and lenalidomide maintenance. She remained clinically well with a good performance status and no active graft-versus-host disease 18 months after transplant. CONCLUSIONS The success of our patient in achieving complete remission has highlighted the efficacy and safety of this novel therapy in the front-line management of PCL.
