RESUMEN

Objectives: This study attempted to develop 2 biodegradable periodontal chips containing Salvadora persica (miswak) or benzyl isothiocyanate (BITC) extracts and evaluate their clinical effectiveness in managing periodontitis. Methods: This clinical trial was conducted at the Faculty of Dentistry, Universiti Teknologi MARA Shah Alam, Selangor, Malaysia, from September 2010 to April 2012. Periodontal chips were formulated using S. persica, benzyl isothiocyanate (BITC) and chitosan extracts. All patients were treated with full mouth scaling and root planing at baseline. Thereafter, the periodontal pockets (≥5 mm in length) were divided into 4 groups: the control group; group 2 (plain chitosan chip); group 3 (S. persica extract); and group 4 (BITC extract). Plaque index (PI), bleeding on probing (BOP), periodontal probing pocket depth and clinical attachment levels were recorded at days 0 and 60 only. Results: A total of 12 patients participated in this study. Overall, 240 periodontal pockets were evaluated. The study revealed significant improvements in PI, BOP and reduction in periodontal pocket depth in all 4 groups (P <0.05). The improvement in clinical attachment level was significantly higher (P <0.001) among the group that received S. persica chips compared to the control and other chip-treated groups. Conclusion: Periodontal chips containing S. persica can be used as adjuncts to treat patients with periodontitis.

RESUMEN

Diabetes Mellitus is one of the oldest diseases known to humankind, dating back to ancient Egypt. The disease is a chronic metabolic disorder that heavily burdens healthcare providers worldwide due to the steady increment of patients yearly. Worryingly, diabetes affects not only the aging population but also children. It is prevalent to control this problem, as diabetes can lead to many health complications. As evolution happens, humankind starts integrating computer technology with the healthcare system. The utilization of artificial intelligence assists healthcare to be more efficient in diagnosing diabetes patients, better healthcare delivery, and more patient eccentric. Among the advanced data mining techniques in artificial intelligence, stacking is among the most prominent methods applied in the diabetes domain. Hence, this study opts to investigate the potential of stacking ensembles. The aim of this study is to reduce the high complexity inherent in stacking, as this problem contributes to longer training time and reduces the outliers in the diabetes data to improve the classification performance. In addressing this concern, a novel machine learning method called the Stacking Recursive Feature Elimination-Isolation Forest was introduced for diabetes prediction. The application of stacking with Recursive Feature Elimination is to design an efficient model for diabetes diagnosis while using fewer features as resources. This method also incorporates the utilization of Isolation Forest as an outlier removal method. The study uses accuracy, precision, recall, F1 measure, training time, and standard deviation metrics to identify the classification performances. The proposed method acquired an accuracy of 79.077% for PIMA Indians Diabetes and 97.446% for the Diabetes Prediction dataset, outperforming many existing methods and demonstrating effectiveness in the diabetes domain.

RESUMEN

INTRODUCTION: Colorectal cancer is a growing global health concern and the number of reported cases has increased over the years. Early detection through screening is critical to improve outcomes for patients with colorectal cancer. In Malaysia, there is an urgent need to optimize the colorectal cancer screening program as uptake is limited by multiple challenges. This study aims to systematically identify and address gaps in screening service delivery to optimize the Malaysian colorectal cancer screening program. METHODS: This study uses a mixed methods design. It focuses primarily on qualitative data to understand processes and strategies and to identify specific areas that can be improved through stakeholder engagement in the screening program. Quantitative data play a dual role in supporting the selection of participants for the qualitative study based on program monitoring data and assessing inequalities in screening and program implementation in healthcare facilities in Malaysia. Meanwhile, literature review identifies existing strategies to improve colorectal cancer screening. Additionally, the knowledge-to-action framework is integrated to ensure that the research findings lead to practical improvements to the colorectal cancer screening program. DISCUSSION: Through this complex mix of qualitative and quantitative methods, this study will explore the complex interplay of population- and systems-level factors that influence screening rates. It involves identifying barriers to effective colorectal cancer screening in Malaysia, comparing current strategies with international best practices, and providing evidence-based recommendations to improve the local screening program.

RESUMEN

BACKGROUND: Heatwaves present health risks globally but there is limited evidence on how temperature perceptions affect activities. This study aimed to examine community perceptions of heat as a potential health hazard and ascertain the current heat protection measures of the residents of the South East Asia Community Observatory (SEACO) in Malaysia. METHODS: In this longitudinal study, we randomly selected community members aged between 18 and 70 years who resided in Segamat district of Johor state, Malaysia. Over 21 days, we conducted three home visits to each participant. During each visit, participants completed a questionnaire consisting of Likert scale, multiple choice, and free text questions and we collected quantitative and qualitative data. These inquiries assessed the participants' perception of heat as health threat, whether or not they took heat preventive measures, and the specific protective measures they routinely employed. Descriptive data analyses were conducted and patterns of protective measures were investigated. FINDINGS: Between March 29 and July 31, 2023, 120 participants (72 women and 48 men) completed 360 questionnaires over three home visits. Initially, 58% participants recognised heat hazards to daily activities, decreasing to 42% and 35% by visits 2 and 3. Participants took preventive measures throughout the day, which was consistently high between 1200 h and 1400 h, with 77% of participants taking preventive measures on visit 1, 82% on visit 2, and 82% on visit 3. Use of preventive measures was also high between 1400 h and 1730 h, with 77% using preventive measure on visit 1, 81% on visit 2, and 79% on visit 3. The most common protective measures were fans (used by 68-88% of participants), drinking more water (70-78% of participants), and resting (44-72% of participants). The least common were relocating to cooler places, removing clothes, and using wet towels (0-2·5%). Despite high temperatures, perceptions of heat risks decreased over time. Participants took basic protections, especially at midday, but improved literacy and affordable cooling options are needed to protect vulnerable rural populations. INTERPRETATION: Our findings underline the need to improve heat literacy and adaptation as only half of the population assessed perceived heat as a potential health hazard and practised limited heat protective measures. Addressing climate change and health necessitates fundamental behavioural changes on the part of individuals and communities, to protect them against the adverse effects of heat.

RESUMEN

Menopausal hormone therapy (MHT) is known to increase the risk of venous thromboembolism (VTE), which includes deep vein thrombosis, pulmonary embolism, and less frequently cerebral vein thrombosis, but the absolute risk for a given patient is very low. After starting MHT, the risk of VTE seems to be at its highest, declining to the non-HRT user baseline level of risk after stopping. Whether estrogen-only or estrogen-progestin HRT combination is linked to a similar risk of VTE is unclear from the available evidence. The aim of this study is to evaluate the risks of developing VTE in relation to different types as well as different modes of administration of MHT through a database search including PubMed, MEDLINE, Google Scholar, Cochrane Library, and others in order to provide the women carers with the up-to-date and evidence-based guidelines and recommendations while counseling the post-menopausal women enquiring on use of hormonal therapies either to alleviate the menopausal symptoms or to prevent the long-term sequelae of estrogen deficiency.


On sait que l'hormonothérapie ménopausique (MHT) augmente le risque de thromboembolie veineuse (TEV), qui comprend la thrombose veineuse profonde, l'embolie pulmonaire et, moins fréquemment, la thrombose veineuse cérébrale, mais le risque absolu pour un patient donné est très faible. Après le début du MHT, le risque de TEV semble être à son plus haut niveau, diminuant jusqu'au niveau de risque de base des non-utilisatrices de THS après l'arrêt. Les preuves disponibles ne permettent pas de savoir si un THS à base d'œstrogène seul ou d'association œstroprogestative est lié à un risque similaire de TEV. Le but de cette étude est d'évaluer les risques de développer une TEV par rapport à différents types ainsi qu'à différents modes d'administration du MHT grâce à une recherche dans des bases de données comprenant PubMed, MEDLINE, Google Scholar, Cochrane Library et autres afin de fournir aux femmes les soignants avec les lignes directrices et recommandations à jour et fondées sur des preuves tout en conseillant les femmes ménopausées qui se renseignent sur l'utilisation de thérapies hormonales, soit pour soulager les symptômes de la ménopause, soit pour prévenir les séquelles à long terme d'une carence en œstrogènes.

RESUMEN

BACKGROUND: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. The qSOFA and procalcitonin are currently used for both diagnostic as well as prognostic purposes. OBJECTIVE: To explore the combined use of day one procalcitonin level and qSOFA scores for prognostication of sepsis-related mortality. DESIGN: This was a prospective observational study. PARTICIPANTS: All patients who fulfilled the inclusion criteria for sepsis with an age of more than 16 years were enrolled in the study. RESULTS: In this study of 211 patients, 15 patients died (7.1%) during hospital stay. Among the 15 patients who died, the highest mortality of 29.4% was seen in patients with qSOFA of "3", qSOFA of "2" had a mortality of 12.8%, qSOFA of "1" had a mortality of 1% and qSOFA of "0" had zero mortality. In this study, procalcitonin had a statistically significant positive correlation/association with both qSOFA and mortality. CONCLUSION: The qSOFA and procalcitonin at presentation to the emergency department in septic patients have a significant correlation with mortality in patients hospitalized with sepsis. Obtaining these two parameters at presentation will help in managing aggressively these patients who at presentation have higher qSOFA and procalcitonin levels.

RESUMEN

The amendment of soils with silicate (Si) compounds is essential to promote growth performance and control Fusarium wilt disease in bananas. Two successive greenhouse trials were conducted at the experimental farm of the University of Putra Malaysia. The treatments were arranged in split plots using a randomized complete block design (RCBD) with four replicates to investigate the effects of Si compounds and application frequency on controlling FOC. Si compounds were used at a constant concentration of 0.1%: T0 (control), T1 (13% SiO2:20% K2O), T2 (26.6% SiO2:13.4% K2O) and T3 (36.2% SiO2:17% Na2O). There were three application frequencies by day intervals (DI): 0DI (without any application), 7DI (12× within 12 weeks after transplanting (WAT)), 15DI (6× within 12 WAT) and 30DI (3× within 12 WAT). From these findings, we observed that the photosynthesis rate started to increase from 10.6 to 19.4 µmol CO2 m-2s-1, when the total chlorophyll content started to increase from 3.85 to 7.61 mgcm-2. The transpiration rate started to increase from a value of 1.94 to 4.31 mmol H2O m-2s-1, when the stomata conductance started to increase from 0.237 to 0.958 mmol m-2s-1. The proline content started to increase from 22.89 to 55.07 µmg-1, when the relative water content started to increase from 42.92 to 83.57%.

RESUMEN

Rice is one of the crops cultivated in Malaysia, and it is the main diet for most of the population. In this study, dispersive liquid-liquid micro-extraction (DLLME) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to develop, optimise and validate a reliable, easy-to-use and quick approach to detect aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1) and aflatoxin G2 (AFG2). The extraction recoveries in DLLME were enhanced by the addition of 5% salt, utilising chloroform as the extraction solvent and acetonitrile as the dispersive solvent. The DLLME parameters - the extraction solvent volume, salt concentration and dispersive solvent volume were optimised with Box-Behnken design (BBD) and response surface methodology (RSM). Under optimised experimental conditions, excellent linearity was obtained with a limit of detection (LOD) ranging from 0.125 to 0.25 ng g-1, a limit of quantitation (LOQ) ranging from 0.25 to 0.3 ng g-1 and a correlation value (R2) of 0.990. The matrix effects were between -11.1% and 19.9%, and recoveries ranged from 87.4% to 117.3%. The optimised and validated method was used effectively to assess aflatoxins contamination in 20 commercial rice samples collected from local supermarkets in Penang, Malaysia. AFB1 was detected at 0.41-0.43 ng g-1 in two rice samples, below the regulatory limit.

RESUMEN

INTRODUCTION: Mixed connective tissue disease (MCTD) is defined as a systemic rheumatic disease characterized by the presence of high titer anti-U1 ribonucleoprotein (U1 RNP) antibodies in combination with clinical features commonly seen in systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis (RA) and polymyositis (PM). CASE PRESENTATION: The annual incidence of MCTD is 1.9 per 100,000 adults. Any organ system can be involved in MCTD however four clinical features that suggest the presence of MCTD rather than another systemic rheumatic disease are Raynaud phenomenon with swollen hands or puffy fingers, absence of severe kidney disease and central nervous system (CNS) disease at first presentation generally, insidious onset of pulmonary hypertension and presence of autoantibodies anti-U1 ribonucleoprotein (U1 RNP), especially antibodies to the 68 kD protein. MCTD, although initially thought to be a disease with a benign course is not considered a valid argument at present. This connective tissue disorder can present with life-threating organ involvement with rapid progression of disease. CONCLUSION: We report two cases of MCTD, one with mild disease and another with life-threatening illness, describing the range of severity at presentation of this disorder.

RESUMEN

BACKGROUND: Inflammatory markers are crucial in diagnosing and monitoring rheumatoid arthritis. Patients with rheumatoid arthritis (RA) live with constant pain that limits their daily activities. Our study highlights the effects of disease activity on the quality of life in patients with rheumatoid arthritis. METHODS: Swollen joint count (SJC), tender joint count (TJC), and visual activity scale (VAS) were utilized to acquire patients' subjective feelings of wellness and their performance of routine daily activities to determine the disease activity. The patient's erythrocyte sedimentation rate (ESR) was measured at the clinical hematology laboratory using the Westergren method. The Quality of Life was rated on a scale of 1 to 10. RESULTS: Our study found that disease activity is inversely proportional to the quality of life. Out of 111 patients, 3 (2.7%) were in remission, 1 (0.9%) had mild disease, 51 (45.9%) had moderate disease, and 56 (50.5%) had high disease activity. The ESR was normal (<20) in 11 patients (9.9%), moderately elevated (20-50) in 56 (50.5%) patients, and very high (>50) in 44 (39.6%) patients. The study revealed that 66% of patients in remission had normal, while 33% had moderately elevated ESR. 12.5% of patients with moderate disease activity had normal ESR, and none with high disease activity had normal ESR. Of 44 patients with high ESR, 7 had moderate disease activity, and 37 had high disease activity. In our study, 60% of patients had a less than 50% quality of life compared to patients with pre-arthritis. CONCLUSION: High disease activity affects the productivity and quality of life in patients with rheumatoid arthritis. Assessing the impact of different interventions on the QOL should be an essential task that can help define a holistic and integrative treatment and rehabilitation model for RA patients.

RESUMEN

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a persistent inflammation of the sinonasal mucosa. CRSwNP treatments are associated with inconsistent efficacy and recurrence of symptoms. Dynorphin 1-17 (DYN 1-17) and its fragments have been shown to modulate the immune response in various inflammatory conditions. This study aimed to investigate the effect of different pH and degrees of inflammation on DYN 1-17 metabolism in human CRSwNP tissues. DYN 1-17 was incubated with grade 3 and grade 4 inflamed tissues of CRSwNP patients at pH 5.5 and pH 7.4 over a range of incubation periods. The resulting fragments were identified using an ultra-performance liquid chromatography (UPLC) system coupled to quadrupole-time of flight (QTOF) mass spectrometry based on their accurate mass. The rate of DYN 1-17 fragmentation was slower at pH 5.5 in comparison to pH 7.4. The extent and rate of metabolism of DYN 1-17 were much lower in grade 3 inflamed tissue (31-32 fragments) than in grade 4 (34-41 fragments). N-Terminal fragments (DYN 1-15, 1-11, 1-10, and 1-6) were metabolized slower at pH 5.5 as compared to pH 7.4. DYN 1-12, 1-8, 2-10, 4-10, 5-10, and 8-14 were only observed under the inflammatory pH while DYN 5-17 and 6-17 were only identified upon incubation with grade 4 CRSwNP tissues. DYN 1-17 metabolism was significantly affected by the pH level and the severity of the inflammation of CRSwNP tissues, indicating the potential roles of DYN 1-17 and its fragments in modulating the inflammatory response and their avenue as therapeutics in future studies.

RESUMEN

Introduction: Unmanned aerial vehicles (UAVs) are used for commercial, medical, public safety, and scientific research purposes in various countries. Methods: This study aimed to explore the acceptance of medical delivery drones among medical practitioners as well as the public community in Malaysia using a knowledge, attitude, and perception (KAP) model and statistical analysis to decrease uncertainty. Bivariate and multivariate analyses of the results were performed in SPSS. Results: A total of 639 respondents took part in the survey, of which 557 complete responses were finally analyzed. The results showed that the overall acceptance rate for medical delivery drones was positive. The acceptance rate was significantly correlated with knowledge, attitude, and perception scores but not with sociodemographic factors. Discussion: Raising awareness and educating the medical as well as public communities regarding the potential role and benefits of drones are therefore important in garnering support for drone usage for medical purposes.

RESUMEN

Colorectal cancer (CRC) signifies a significant healthcare challenge in Southeast Asia. Despite advancements in screening approaches and treatment modalities, significant medical gaps remain, ranging from prevention and early diagnosis to determining targeted therapy and establishing personalized approaches to managing CRC. There is a need to expand more validated biomarkers in clinical practice. An advanced technique incorporating high-throughput mass spectrometry as a liquid biopsy to unravel a repertoire of glycoproteins and glycans would potentially drive the development of clinical tools for CRC screening, diagnosis and monitoring, and it can be further adapted to the existing standard-of-care procedure. Therefore this review offers a perspective on glycoproteomics-driven liquid biopsy and its potential integration into the clinical care of CRC in the southeast Asia region.

RESUMEN

Sacha Inchi (Plukenetia volubilis L.) is a plant native in the Amazon rainforest in South America known for its edible seeds, which are rich in lipids, proteins, vitamin E, polyphenols, minerals, and amino acids. Rural communities in developing nations have been using this plant for its health benefits, including as a topical cream for rejuvenating and revitalising skin and as a treatment for muscle pain and rheumatism. Although Sacha Inchi oil has been applied topically to soften skin, treat skin diseases, and heal wounds, its protein-rich seeds have not yet received proper attention for extensive investigation. Proteins in Sacha Inchi seeds are generally known to have antioxidant and antifungal activities and are extensively used nowadays in making protein-rich food alternatives worldwide. Notably, large-scale use of seed proteins has begun in nanoparticle and biofusion technologies related to the human health-benefitting sector. To extract and identify their proteins, the current study examined Sacha Inchi seeds collected from the Malaysian state of Kedah. Our analysis revealed a protein concentration of 73.8 ± 0.002 mg/g of freeze-dried seed flour. Employing liquid chromatography-tandem mass spectrometry (LC-MS/MS) and PEAKS studio analysis, we identified 217 proteins in the seed extract, including 152 with known proteins and 65 unknown proteins. This study marks a significant step towards comprehensively investigating the protein composition of Sacha Inchi seeds and elucidating their potential applications in the food and biopharmaceutical sectors. Our discoveries not only enhance our knowledge of Sacha Inchi's nutritional characteristics but also pave the way for prospective research and innovative advancements in the realms of functional food and health-related domains.

RESUMEN

The article presents data on the quantification of gallic acid (GA) and the assessment of the antioxidant and anti-inflammatory properties of Kacip Fatimah (Labisia pumila Benth. & Hook. f.) leaves using various solvents. GA was quantified using high-performance liquid chromatography analysis. Total phenolic content (TPC) was assessed using the Folin-Ciocalteu method. The antioxidant activities were evaluated using xanthine oxidase superoxide (XOD-Superoxide) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays, while anti-inflammatory activities were examined through lipoxygenase (LOX) and xanthine oxidase (XOD) inhibition assays. Results showed that the water-extracted sample had the highest GA and TPC among the solvents tested, along with the strongest inhibition activities in the XOD-Superoxide and DPPH assays. Both water and ethanol extracts showed significant inhibitory activities in the LOX assay but were inactive in the XOD assay. These findings suggest that the bioactivity of L. pumila leaf extract is associated with GA and TPC. GA and TPC strongly correlated with antioxidant and anti-inflammatory activities, except for the XOD assay. The dataset highlights the potential dietary benefits of L. pumila leaves as a natural source of antioxidants and anti-inflammatory properties for pharmaceutical and nutraceutical applications.

RESUMEN

Styrax sp. is a valuable latex-producing plant in North Sumatra Province, Indonesia, which requires sustainable land use practices to maintain its production and ecological value. This study aimed to assess the land characteristics and suitability of Styrax sp. in Humbang Hasundutan Regency, North Sumatra Province, to support the development of sustainable land use practices for the cultivation of this plant. The study employed a survey method to collect soil samples and evaluated the land suitability using a matching method and Geographic Information System (GIS) techniques. The results showed that Styrax sp. had moderately suitable land suitability in three villages in Humbang Hasundutan Regency. The limiting factors for land suitability were identified as rooting media, nutrient retention, water availability, and erosion hazard. These findings have important implications for the development of sustainable land use practices for Styrax sp. cultivation in the region, which can contribute to the conservation of this valuable plant species and the maintenance of ecological balance. Overall, this study provides valuable insights into the land characteristics and suitability of Styrax sp. in North Sumatra Province and highlights the importance of sustainable land use practices for the conservation of valuable plant species.

RESUMEN

Breakfast is often referred to as the "most important meal of the day" in shaping diet quality. This study established the patterns of breakfast consumption in Malaysia and assessed its contribution to the overall quality of the diet based on the 24 h recall data from the nationally representative and cross-sectional Malaysian Food Barometer (MFB, second data collection, 2018) to assess breakfast intake among adults (n = 1604). Diet quality was measured using the Nutrient Rich Food index (NRF) 9.3. The nutritional profile of breakfast was compared across tertiles of NRF 9.3. Overall, 89% of Malaysians consume breakfast. Breakfast was found to provide 474 kcal on average. The Malaysian daily diet was found to be rich in fats, saturated fats, total sugars, and sodium, with breakfast making a significant contribution to the daily intakes of these nutrients. Intakes of fiber, potassium, calcium, vitamins C and D, folate, iron, zinc, and magnesium were low. Breakfast was related to the overall diet quality measured by the NRF index. This study revealed that the breakfasts consumed by Malaysian adults were found to be nutritionally unbalanced. This analysis could serve as a basis for nutrient recommendations grounded in existing social and cultural breakfast patterns.

RESUMEN

BACKGROUND: Poor employment rate among psychiatric patients is poorly discussed. PURPOSE: To share our strategies in boosting employment rate among stable psychiatric patients and discuss the lessons learnt. PARTICULAR FOCUS: Multifaceted strategies were remodelled to ensure a three-dimensional optimisation: (1) strengthening clinical service to ensure stable disease and appropriate patient selection through battery of assessments, (2) provision of psychosocial support to boost self-esteem and foster discipline among patients through encouragement, guidance and regular monitoring by the multidisciplinary community mental health team and (3) encourage willingness and confidence among stakeholders and local market to host job opportunities to stable mental health patients. OVERVIEW: The yearly employment rate among our stable psychiatric patients under supported employment programme from 2020 to 2021 was 28.6% (2/7) and 30.0% (3/10), respectively. A qualitative survey found the main hindrance to recruitment were employers' scepticism on work performance, while poor work retention was due to patients' lack of specific skill set and discipline to adhere to routine. We restructured our supported employment programme by adding the role of community mental health facility to foster discipline and routine for 6 months prior to referral to a job coach. Until June 2022, two out of five patients managed to secure job positions (40.0%). Despite our efforts to improve employment with the instituted remedial strategy, we still fail to reach the minimum standard set by ministry. Future plan will focus on tailoring individual interests to a specific set of skills that match industrial expectation prior to seeking employment. Additionally, enhancing public education using social media may foster better inclusion of psychiatric patients and social acceptance.

RESUMEN

Analyzing metabolic pathways in systems biology requires accurate kinetic parameters that represent the simulated in vivo processes. Simulation of the fermentation pathway in the Saccharomyces cerevisiae kinetic model help saves much time in the optimization process. Fitting the simulated model into the experimental data is categorized under the parameter estimation problem. Parameter estimation is conducted to obtain the optimal values for parameters related to the fermentation process. This step is essential because insufficient identification of model parameters can cause erroneous conclusions. The kinetic parameters cannot be measured directly. Therefore, they must be estimated from the experimental data either in vitro or in vivo. Parameter estimation is a challenging task in the biological process due to the complexity and nonlinearity of the model. Therefore, we propose the Artificial Bee Colony algorithm (ABC) to estimate the parameters in the fermentation pathway of S. cerevisiae to obtain more accurate values. A metabolite with a total of six parameters is involved in this article. The experimental results show that ABC outperforms other estimation algorithms and gives more accurate kinetic parameter values for the simulated model. Most of the estimated kinetic parameter values obtained from the proposed algorithm are the closest to the experimental data.

RESUMEN

Bacterial panicle blight (BPB) disease is a dreadful disease in rice-producing countries. Burkholderia glumae, a Gram-negative, rod-shaped, and flagellated bacterium was identified as the primary culprit for BPB disease. In 2019, the disease was reported in 18 countries, and to date, it has been spotted in 26 countries. Rice yield has been reduced by up to 75% worldwide due to this disease. Interestingly, the biocontrol strategy offers a promising alternative to manage BPB disease. This review summarizes the management status of BPB disease using biological control agents (BCA). Bacteria from the genera Bacillus, Burkholderia, Enterobacter, Pantoea, Pseudomonas, and Streptomyces have been examined as BCA under in vitro, glasshouse, and field conditions. Besides bacteria, bacteriophages have also been reported to reduce BPB pathogens under in vitro and glasshouse conditions. Here, the overview of the mechanisms of bacteria and bacteriophages in controlling BPB pathogens is addressed. The applications of BCA using various delivery methods could effectively manage BPB disease to benefit the agroecosystems and food security.
