    The existence of word stress in Indonesian languages has been controversial. Recent acoustic analyses of Papuan Malay suggest that this language has word stress, counter to other studies and unlike closely related languages. The current study further investigates Papuan Malay by means of lexical (non-acoustic) analyses of two different aspects of word stress. In particular, this paper reports two distribution analyses of a word corpus, 1) investigating the extent to which stress patterns may help word recognition and 2) exploring the phonological factors that predict the distribution of stress patterns. The facilitating role of stress patterns in word recognition was investigated in a lexical analysis of word embeddings. The results show that Papuan Malay word stress (potentially) helps to disambiguate words. As for stress predictors, a random forest analysis investigated the effect of multiple morpho-phonological factors on stress placement. It was found that the mid vowels /ɛ/ and /ɔ/ play a central role in stress placement, refining the conclusions of previous work that mainly focused on /ɛ/. The current study confirms that non-acoustic research on stress can complement acoustic research in important ways. Crucially, the combined findings on stress in Papuan Malay so far give rise to an integrated perspective to word stress, in which phonetic, phonological and cognitive factors are considered.

    Numerous plant secondary metabolites have remarkable impacts on both food supplements and pharmaceuticals for human health improvement. However, higher plants can only generate small amounts of these chemicals with specific temporal and spatial arrangements, which are unable to satisfy the expanding market demands. Cyanobacteria can directly utilize CO2, light energy, and inorganic nutrients to synthesize versatile plant-specific photosynthetic intermediates and organic compounds in large-scale photobioreactors with outstanding economic merit. Thus, they have been rapidly developed as a "green" chassis for the synthesis of bioproducts. Flavonoids, chemical compounds based on aromatic amino acids, are considered to be indispensable components in a variety of nutraceutical, pharmaceutical, and cosmetic applications. In contrast to heterotrophic metabolic engineering pioneers, such as yeast and Escherichia coli, information about the biosynthesis flavonoids and their derivatives is less comprehensive than that of their photosynthetic counterparts. Here, we review both benefits and challenges to promote cyanobacterial cell factories for flavonoid biosynthesis. With increasing concerns about global environmental issues and food security, we are confident that energy self-supporting cyanobacteria will attract increasing attention for the generation of different kinds of bioproducts. We hope that the work presented here will serve as an index and encourage more scientists to join in the relevant research area.

    PURPOSE/OBJECTIVE(S): While rapid innovations in radiation treatment improve tumor controls and minimize toxicity, there is a dearth of quality training in resource-limited settings globally to ensure all radiation oncologists keep pace with the latest advances. We aim to create a learning platform shared by centers in Southeast Asia and to deliver quality training to participants with a curated virtual curriculum. To produce a comprehensive curriculum for countries enrolling in a non-profit organization training program, a needs assessment was conducted for registered participants.

    MATERIALS/METHODS: Participants interested in a 12-week virtual training program completed a needs assessment survey via a data collection web application. The survey included demographics, practice characteristics, and interests in contouring and plan evaluation education and training. Herein we provide descriptive statistics of the reports from participant surveys.

    RESULTS: Across Thailand, Myanmar, Malaysia, Indonesia, and Nepal, 116 participants (82 attendings, 33 residents, 1 other) responded from 23 participating medical institutions (20 public, 3 private). The average number of radiation oncologists per medical institution was 6.81 (range 1-30) and radiation oncology residents was 17.50 (range 2-56). In the 7 centers with residency programs, 0 (0%) indicated that residents were solely involved in contouring, 5 (71.4%) that residents were jointly involved in contouring with attendings, and 2 (28.6%) that attendings contour without residents. Commonly cited obstacles to providing radiotherapy included: patient financial barriers (61.4%), inadequate training (51.8%), too many patients (48.2%), lack of modern equipment (40.4%), shortage of staff (39.5%), and malfunctioning equipment (36.8%). The most common, top-rated obstacle was inadequate training (24.8%). The most seen disease sites were head and neck (38.2%) and breast (30.3%). Respondent time spent contouring the target was greatest for head and neck, pediatric, and lymphoma disease sites with 66 (56.9%), 59 (50.8%), and 46 (29.3%) indicating more than 1 hour, respectively. Respondent time spent contouring the normal tissues was greatest for head and neck, pediatric, and CNS disease sites with 51 (44%), 46 (39.7%), and 30 (26.1%) indicating more than 1 hour. For head and neck cases, 34 (29.3%) respondents typically contour 6-10 Organs at Risk (OARs), 47 (40.5%) contour 11-15 OARs, 18 (15.5%) contour 16-20 OARs, and 15 (12.9%) contour > 20 OARs. 85 (76.3%) respondents believe their practice would most benefit from head and neck contouring education, while 114 (98.3%) were interested in receiving contouring and plan evaluation training.

    CONCLUSION: The biggest physician-reported obstacle to providing radiotherapy in Southeast Asian practices is inadequate training. There is both high need and interest for well-developed virtual training, particularly in head and neck contouring, which currently appears time-intensive and heterogeneous among practices.

    LIMK1 and LIMK2 are involved in the regulation of cellular functions that depend on the dynamics of actin cytoskeleton. Disregulation of LIM kinases has been associated with diseases, such as tumor progression and metastasis, viral infection, and ocular diseases. Motivated by this, numerous studies have been carried out to discover small organic molecules capable of inhibiting LIM kinase effectively and selectively. In this review, a comprehensive survey of small organic molecules for LIM kinase inhibitors is reported, together with SAR study results, and the synthesis of these inhibitors.

    BACKGROUND: The aggressive marketing of breastmilk substitutes (BMS) reduces breastfeeding, and harms child and maternal health globally. Yet forty years after the World Health Assembly adopted the International Code of Marketing of Breast-milk Substitutes (The Code), many countries are still to fully implement its provisions into national law. Furthermore, despite The Code, commercial milk formula (CMF) markets have markedly expanded. In this paper, we adopt the Philippines as a case study to understand the battle for national Code implementation. In particular, we investigate the market and political strategies used by the baby food industry to shape the country's 'first-food system', and in doing so, promote and sustain CMF consumption. We further investigate how breastfeeding coalitions and advocates have resisted these strategies, and generated political commitment for a world-leading breastfeeding policy framework and protection law (the 'Milk Code'). We used a case study design and process tracing method, drawing from documentary and interview data.

    RESULTS: The decline in breastfeeding in the Philippines in the mid-twentieth Century associated with intensive BMS marketing via health systems and consumer advertising. As regulations tightened, the industry more aggressively promoted CMFs for older infants and young children, thereby 'marketing around' the Milk Code. It established front groups to implement political strategies intended to weaken the country's breastfeeding policy framework while also fostering a favourable image. This included lobbying government officials and international organizations, emphasising its economic importance and threats to foreign investment and trade, direct litigation against the government, messaging that framed marketing in terms of women's choice and empowerment, and forging partnerships. A resurgence in breastfeeding from the mid-1980s onwards reflected strengthening political commitment for a national breastfeeding policy framework and Milk Code, resulting in-turn, from collective actions by breastfeeding coalitions, advocates and mothers.

    CONCLUSION: The Philippines illustrates the continuing battle for worldwide Code implementation, and in particular, how the baby food industry uses and adapts its market and political practices to promote and sustain CMF markets. Our results demonstrate that this industry's political practices require much greater scrutiny. Furthermore, that mobilizing breastfeeding coalitions, advocacy groups and mothers is crucial to continually strengthen and protect national breastfeeding policy frameworks and Code implementation.

    Introduction: Mycobacterium tuberculosis infections are associated with severe local inflammatory reactions, which may be life-threatening and lead to tuberculosis pathogenesis and associated complications. Inorganic nanolayers have been vastly exploited for biomedical applications (especially in drug delivery) because of their biocompatible and biodegradable nature with the ability to release a drug in a sustained manner. Herein, we report a new nanodelivery system of inorganic nanolayers based on magnesium layered hydroxides (MgLH) and a successfully intercalated anti-tuberculosis drug para-aminosalicylic acid (PAS).

    Methods: The designed anti-tuberculosis nanodelivery composite, MgLH-PAS, was prepared by a novel co-precipitation method using MgNO3 as well MgO as starting materials.

    Results: The designed nano-formulation, PAS-MgLH, showed good antimycobacterial and antimicrobial activities with significant synergistic anti-inflammatory effects on the suppression of lipopolysaccharide (LPS) stimulated inflammatory mediators in RAW 264.7 macrophages. The designed nano-formulation was also found to be biocompatible with human normal lung cells (MRC-5) and 3T3 fibroblast cells. Furthermore, the in vitro release of PAS from PAS-MgLH was found to be sustained in human body simulated phosphate buffer saline (PBS) solutions of pH 7.4 and pH 4.8.

    Discussion: The results of the present study are highly encouraging for further in vivo studies. This new nanodelivery system, MgLH, can be exploited in the delivery of other drugs and in numerous other biomedical applications as well.

    Purpose: Older people often have chronic diseases which require a continuity of care over the long term. Countries undergoing population aging need to ensure that older people are receiving the care they need. This study assesses the prevalence of, reasons for, and factors associated with unmet healthcare needs among older people individuals in Malaysia.

    Patients and Methods: This cross-sectional study used data collected during 2018-2020 from 1204 older adults aged 60 and older selected from Selangor state, Malaysia. A comprehensive face-to-face interview based on the Bahasa Malaysia version of the Japan Gerontological Evaluation Study (JAGES-BM) questionnaire was administered to gain information on unmet healthcare needs, socioeconomic factors, health-related factors, and measures of function (activities of daily living, depression, visual impairment, hearing impairment, memory impairment, and walking impairment). Multivariate logistic regression was used to analyze factors associated with their unmet healthcare needs.

    Results: Overall, the percentage of older people respondents with unmet healthcare needs is 6.6%. The most reported reasons for forgoing or delaying healthcare were lack of knowledge about healthcare and financial barriers to care. The inability to travel alone (adjusted odds ratio [aOR] 2.51), being overweight (aOR 1.88), and having self-reported depression (aOR 2.23) were each associated with a higher likelihood of having unmet healthcare needs in their daily life.

    Conclusion: The prevalence of unmet healthcare needs among older people in this part of Malaysia is lower than that reported in some other countries. However, it is possible to further reduce unmet healthcare needs by improving people's knowledge and attitudes about appropriate healthcare utilization, strengthening financial protection measures and providing support to people at high risk of having unmet healthcare needs.

    Background: Healthcare-associated infections (HAI) are considered one of the most common adverse events in health care service provision. In order to prevent the occurrence of HAIs, it is important to implement several prevention strategies.

    Objectives: This study aims to determine the incidence of healthcare-associated infections in a military hospital in Alkharj and the adherence to the HAIs' prevention strategies.

    Methods: This study included exporting data for all infected cases confirmed by the infection disease specialists in 2019. The data were collected from the reports that were written by infection control unit and infectious disease department.

    Results: The rate of healthcare associated infections (HAIs) in 2019 was 0.43% of total patient admissions. The rate of central line associated bloodstream infections in 2019 was 1.15 per 1000 central line days. The rate of catheter associated urinary tract infections in 2019 was 1.00 per 1000 catheter days. The rate of ventilator associated pneumonia in 2019 was 2.11 per 1000 ventilator days and the rate of surgical site infections in 2019 was 0.41 %.

    Conclusion: The rate of overall healthcare-associated infections (HAI) was low. The compliance rate of health care workers to preventive measures that control HAIs was generally high but there was a need for more awareness particularly regarding personal protective equipment and hand hygiene. So it is important to attend more awareness activities and workshops particularly regarding personal protective equipment and hand hygiene. Furthermore, infection control unit and infectious disease department in the hospital should support the robust HAI prevention programs.

    Autoinjectors are self-injectable devices; they are important class of medical devices which can deliver drugs through subcutaneous or intramuscular route. They enclose prefilled syringes or cartridges which are driven by a spring system. The major benefits of this device are easy self-administration, improved patient compliance, reduced anxiety, and dosage accuracy. Immediate treatment during emergency conditions such as anaphylaxis, migraine, and status epilepticus or for chronic conditions like psoriasis, diabetes, multiple sclerosis, and rheumatoid arthritis, Reformulation of first-generation biologics, technical advancements, innovative designs, patient compliance, overwhelming interest for self-administration all these made entry of more and more autoinjectors into use. In this review, intensive efforts have been made for exploring the different types of currently available autoinjectors for the management of emergency and chronic diseases.

    Leiomyomatosis peritonealis disseminata (LPD) is a rare benign condition characterized by multiple smooth muscle implants in the peritoneal cavity. The clinical presentation is usually nonspecific abdominal discomfort and nontender abdominal mass. Preoperative imaging usually points to suggests malignancy due to its unusual location, but the diagnosis can only be confirmed by histopathological examination. We share 18F-Fluorodeoxyglucose positron emission tomography-computed tomography images of a 43-year-old woman diagnosed with LPD and briefly discuss the clinical aspects of this disease.

    Introduction: Growing interest has focused on the relation between chronic endometritis (CE) or asymptomatic inflammation of the endometrium and recurrent miscarriage (RM).The aim of the study was to assess the relation between CE and RM and the accuracy of hysteroscopy in diagnosing CE.

    Material and methods: One hundred and ten (110) women with unexplained RM were included in this study. Participants were subjected to diagnostic hysteroscopy for uterine cavity, and endometrium evaluation. The diagnosis of CE during hysteroscopic examination was based on CE-related hysteroscopic signs (micro-polyps, stromal edema, and/or hyperemia). At the end of hysteroscopy, an endometrial biopsy was taken from participants for culture, and immunohistochemical (IHC) staining. Collected data were analyzed to assess the relation between CE and RM and the accuracy of hysteroscopy in diagnosing CE.

    Results: The prevalence of CE in women with RM was 31.8% using CE-related hysteroscopic signs, while it was 38.2% using IHC staining and endometrial cultures (p = 0.4). CE-related hysteroscopic signs had 64.1% sensitivity, 85.9% specificity, 71.4% positive predictive value (PPV), 81.3% negative predictive value (NPV), and 78.2% overall accuracy in diagnosing CE. Most cases of CE (> 81%) were caused by Mycoplasma and common pathogens.

    Conclusions: The prevalence of CE in women with RM was 31.8% using CE-related hysteroscopic signs, while it was 38.2% using IHC staining and endometrial cultures. CE-related hysteroscopic signs had 64.1% sensitivity, 85.9% specificity, 71.4% PPV, 81.3% NPV, and 78.2% overall accuracy in diagnosing CE. Most cases of CE (> 81%) were caused by Mycoplasma and common pathogens.

    Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with multisystem involvement that follows a relapsing and remitting course. It is characterized by an immune-mediated response to own body defense mechanism and mistakenly attacked healthy cells of the skin, joints, kidneys, blood cells, and nervous system. Cerebral lupus refers to a constellation of neurological and/or behavioral clinical syndromes in patients with SLE. The spectrum of presentation can vary widely ranging from mild symptoms such as headaches, slight cognitive dysfunction, and mood disorders to more serious conditions like seizures, stroke, or coma. This case report is about a case of cerebral lupus manifested with symptoms of Parkinsonism. The purpose of this case report is to share an uncommon occurrence of cerebral lupus which manifested as Parkinsonism and to highlight the importance of early diagnosis of the condition which is potentially reversibility with prompt treatment [4].

    Background: Prostatic carcinoma is the commonest malignancy among men. It usually metastasizes to the spine and regional lymph nodes. However, it is extremely rare for it to metastasize to the mediastinum.

    Case presentation: An elderly man presented to us with progressive onset of bilateral lower limb weakness which was associated with thoracic radiculopathy and urinary incontinence. An urgent magnetic resonance imaging (MRI) of the spine showed severe cord compression with enlarged prostate and superior mediastinal mass. A computed tomography (CT) guided biopsy of the mediastinal mass was suggestive of prostatic malignancy. An emergency posterior instrumentation and fusion (PSIF) in prone position was successfully done. Histopathological examination of the spine showed malignant glandular tissues, suggestive of prostate.

    Discussion: A huge mediastinal mass can compromise the cardiorespiratory system and is very challenging for the anaesthetist to safely secure the airway for surgical procedures. Androgen deprivation therapy (ADT) for patients with metastatic prostatic carcinoma can be achieved either by medical castration or with bilateral orchidectomy.

    Conclusion: It is extremely uncommon for a prostatic carcinoma to metastasize to the mediastinum. Patients with a huge mediastinal mass possess risks of cardiorespiratory collapse perioperatively. Chemoradiotherapy and androgen deprivation therapy (ADT) can be utilized for metastatic prostatic carcinoma with good outcomes.

    Problem: The novel coronavirus disease 2019 (COVID-19) pandemic adversely affected the preparation of Malaysia's National Health and Morbidity Survey for 2020 because conducting it would expose data collectors and participants to an increased risk of infection.

    Context: The survey is nationally representative and community based and is conducted by the Institute for Public Health, part of the National Institutes of Health, to generate health-related evidence and to support the Malaysian Ministry of Health in policy-making. Its planned scope for 2020 was the seroprevalence of communicable diseases such as hepatitis B and C.

    Action: Additional components were added to the survey to increase its usefulness, including COVID-19 seroprevalence and facial anthropometric studies to ensure respirator fit. The survey's scale was reduced, and data collection was changed from including only face-to-face interviews to mainly self-administered and telephone interviews. The transmission risk to participants was reduced by screening data collectors before the survey and fortnightly thereafter, using standard droplet and contact precautions, ensuring proper training and monitoring of data collectors, and implementing other administrative infection prevention measures.

    Outcome: Data were collected from 7 August to 11 October 2020, with 5957 participants recruited. Only 4 out of 12 components of the survey were conducted via face-to-face interview. No COVID-19 cases were reported among data collectors and participants. All participants were given their hepatitis and COVID-19 laboratory test results; 73 participants with hepatitis B and 14 with hepatitis C who had been previously undiagnosed were referred for further case management.

    Discussion: Preparing and conducting the National Health and Morbidity Survey during the COVID-19 pandemic required careful consideration of the risks and benefits, multiple infection prevention measures, strong leadership and strong stakeholder support to ensure there were no adverse events.

    The electroencephalogram (EEG) signal data were obtained from Yayasan Kita dan Buah Hati (YKBH), Jakarta, Indonesia and collected using a Brain Maker EEG machine with 19 channels. The sampling rate of the machine was 250 Hz. Fourteen participants (five females and nine males) participated in the data collection. A psychologist verified that seven of them were addicted to porn, and seven were healthy teenagers. The EEG data were recorded using one protocol with nine tasks for 10 min. The three stages were the baseline (tasks with eyes closed and open), emotional state (happy, calm, sad and fearful tasks) and main (15-words memorisation task, executive task and 15-words recall task) stages. The data obtained was used to analyse the signal pattern of pornography addiction amongst teenagers, as well as the emotional signal pattern and working memory capacity.

    Background: COVID-19 has rapidly spread across the globe. Critical to the control of COVID-19 is the characterisation of its epidemiology. Despite this, there has been a paucity of evidence from many parts of the world, including Malaysia. We aim to describe the epidemiology of COVID-19 in Malaysia to inform prevention and control policies better.

    Methods: Malaysian COVID-19 data was extracted from 16 March 2020 up to 31 May 2021. We estimated the following epidemiological indicators: 7-day incidence rates, 7-day mortality rates, case fatality rates, test positive ratios, testing rates and the time-varying reproduction number (Rt).

    Findings: Between 16 March 2020 and 31 May 2021, Malaysia has reported 571,901 cases and 2,796 deaths. Malaysia's average 7-day incidence rate was 26•6 reported infections per 100,000 population (95% CI: 17•8, 38•1). The average test positive ratio and testing rate were 4•3% (95% CI: 1•6, 10•2) and 0•8 tests per 1,000 population (95% CI: <0•1, 3•7), respectively. The case fatality rates (CFR) was 0•6% (95% CI: <0•1, 3•7). Among the 2,796 cases who died, 87•3% were ≥ 50 years.

    Interpretation: The public health response was successful in the suppression of COVID-19 transmission or the first half of 2020. However, a state election and outbreaks in institutionalised populations have been the catalyst for more significant community propagation. This rising community transmission has continued in 2021, leading to increased incidence and strained healthcare systems. Calibrating NPI based on epidemiological indicators remain critical for us to live with the virus. (243 words).

    Funding: This study is part of the COVID-19 Epidemiological Analysis and Strategies (CEASe) Project with funding from the Ministry of Science, Technology and Innovation (UM.0000245/HGA.GV).

    This research examines how financial transformative power sector reforms affect energy efficiency and the economy in a sample of economies from South Asia, the Middle East, and Europe. We applied two stages of OLS, Bayesian VAR, and Data Envelopment Analysis (DEA) methods to a panel data set from 1995 to 2018. According to empirical findings, institutional deficiency has a negative effect on electricity reforms, implying that the greater the impact of reforms on electricity performance, the higher the institutional efficiency, A collection of reform initiatives involving a variety of reform agencies will boost energy efficiency by up to 13% and per capita electricity access by 62%. Despite recent reforms and regulatory measures, the electricity sector continues to face challenges in terms of private investment and structural flaws such as energy inefficiency, significant technological and financial losses, low power quality, and outdated transmission and network infrastructure. Interestingly 13.2% increases can be found in energy efficiency after electricity reforms. Unlike previous studies, our findings reveal a conflict between the broader economic effects and the welfare impact on electricity consumers.

    The sequence diversity of natural and laboratory populations of Brugia pahangi and Brugia malayi was assessed with Illumina resequencing followed by mapping in order to identify single nucleotide variants and insertions/deletions. In natural and laboratory Brugia populations, there is a lack of sequence diversity on chromosome X relative to the autosomes (πX/πA = 0.2), which is lower than the expected (πX/πA = 0.75). A reduction in diversity is also observed in other filarial nematodes with neo-X chromosome fusions in the genera Onchocerca and Wuchereria, but not those without neo-X chromosome fusions in the genera Loa and Dirofilaria. In the species with neo-X chromosome fusions, chromosome X is abnormally large, containing a third of the genetic material such that a sizable portion of the genome is lacking sequence diversity. Such profound differences in genetic diversity can be consequential, having been associated with drug resistance and adaptability, with the potential to affect filarial eradication.
