    PURPOSE: Pediatric solid tumors require coordinated multidisciplinary specialist care. However, expertise and resources to conduct multidisciplinary tumor boards (MDTBs) are lacking in low- and middle-income countries (LMICs). We aimed to profile the landscape of pediatric solid tumor care and practices and perceptions on MDTBs among pediatric solid tumor units (PSTUs) in Southeast Asian LMICs.

    METHODS: Using online surveys, availability of specialty manpower and MDTBs among PSTUs was first determined. From the subset of PSTUs with MDTBs, one pediatric surgeon and one pediatric oncologist from each center were queried using 5-point Likert scale questions adapted from published questionnaires.

    RESULTS: In 37 (80.4%) of 46 identified PSTUs, availability of pediatric-trained specialists was as follows: oncologists, 94.6%; surgeons, 91.9%; radiologists, 54.1%; pathologists, 40.5%; radiation oncologists, 29.7%; nuclear medicine physicians, 13.5%; and nurses, 81.1%. Availability of pediatric-trained surgeons, radiologists, and pathologists was significantly associated with the existence of MDTBs (P = .037, .005, and .022, respectively). Among 43 (89.6%) of 48 respondents from 24 PSTUs with MDTBs, 90.5% of oncologists reported > 50% oncology-dedicated workload versus 22.7% of surgeons. Views on benefits and barriers did not significantly differ between oncologists and surgeons. The majority agreed that MDTBs helped to improve accuracy of treatment recommendations and team competence. Complex cases, insufficient radiology and pathology preparation, and need for supplementary investigations were the top barriers.

    CONCLUSION: This first known profile of pediatric solid tumor care in Southeast Asia found that availability of pediatric-trained subspecialists was a significant prerequisite for pediatric MDTBs in this region. Most PSTUs lacked pediatric-trained pathologists and radiologists. Correspondingly, gaps in radiographic and pathologic diagnoses were the most common limitations for MDTBs. Greater emphasis on holistic multidisciplinary subspecialty development is needed to advance pediatric solid tumor care in Southeast Asia.

    Introduction: Low job satisfaction among healthcare workers may lead to high turnover intention, poor job perfor-mance, high absenteeism, and low patient satisfaction. Global and local needs for health workforce are increasing in trend to meet current health demands. Addressing job satisfaction of the healthcare workers is a practical way to uti-lise the available human resources optimally. The main aim of this study is to determine job satisfaction level and its associated factors among healthcare workers in health clinics under the Petaling District Health Office jurisdiction in Selangor, Malaysia. Methods: A cross-sectional study was conducted among healthcare workers in ten health clinics in Petaling District from April until May 2019. Simple random sampling method proportionate to the number of staffs from each health clinics was done. A structured self-administered questionnaire was used. Results: The response rate was 93%. Majority of the respondent were female (83%), married (82%), diploma holder (41%), nurses (33%) and working in health clinics with specialists (93%). The job satisfaction mean score for the studied population was 4.46 (SD = 0.72). Self-rated physical health and mental stress status were significantly associated with job satisfaction (p < 0.001). Conclusion: The job satisfaction level of the studied population was comparable to other local studies and higher than studies from Iran, Ethiopia and China. Extra attention should be given to healthcare workers with poor physical health and poor mental stress. More objective study on physical health and mental stress is required.

    INTRODUCTION: Educating a mother of a premature baby and providing a structured written educational information can enhance better understanding and practice. This article describes the development and implementation of a health educational package for preemie moms in the care of their premature baby after neonatal intensive care unit discharge.

    SUBJECTS AND METHODS: The package known as "Preemie Mom: A Guide for You" was designed based on Stufflebeam's model and has four phases: (1) content evaluation from available sources of information, (2) input evaluation based on mothers' need related to premature baby care, (3) process evaluation for package designing and content drafting, and (4) product evaluation to determine its feasibility. The contents were extracted and collated for validation by consulting various specialists in related fields. A final draft was drawn based on comments given by experts. Comments from the mothers were taken for formatting, visual appearance, and content flow for easy understanding and usage.

    RESULTS: All ten existing articles and eight relevant documents were gathered and critically appraised. The package was designed based on 11 main components related to the care of premature baby after discharge. The content validation was accepted at a minimum score of 0.85 for the item-level content validity index analysis. Both experts and mothers were agreed that the package is easy to use and well accepted as a guide after discharge. The agreement rate by the mothers was at 93.33% and greater for the front page, writing style, structure, presentation, and motives of the package.

    CONCLUSIONS: "Preemie Mom: A Guide for You" is a validated health educational package and ready to be used to meet the needs of the mother for premature baby care at home.

    Cervical spinal cord injury (SCI) often causes debilitating loss of function of the upper limb. Upper extremity reconstruction surgery can restore some of the upper limb function in tetraplegic patients with SCI. The procedures are typically muscle-tendon unit transfer surgeries, which redistribute the remaining functional muscles to restore active elbow extension, key grip, and finger grasping. In addition to the tendon transfer surgeries, nerve transfers have emerged recently and are showing promising results. However, despite more than half of the tetraplegic patients can benefit from upper limb surgery, only a few of them receive the procedures. This missed opportunity may be due to the lack of communication between SCI specialists and hand surgeons, or the lack of awareness of such options among the specialists and patients. In this review, we provide a basic overview of upper limb reconstruction in tetraplegic patients with target audience of SCI specialists for their better understanding of the basic concept of surgery and information for patient consultation before referring to hand surgeons.

    The Combined Cleft Clinic at the University Hospital, Kuala Lumpur was organised in 1992. The team consists of Plastic Surgeon, Orthodontists, Speech therapist, Ear, Nose and Throat Surgeon, Audiologist, medical officers and the nurses. We attend the clinic on a regular basis. Specialists from other medical and dental disciplines as well as the members of the Cleft Lip and Palate Association of Malaysia (CLAPAM) do occasionally participate in this set-up.The team members formulate treatment plans for each cleft patient, monitor the patient's growth and development and manage the patient at different stages according to the individual needs. To date, the idea of team approach and an establishment of a centre towards management of cleft patients seem to be the most ideal as the patients are benefiting total treatment and care from various specialists from only one place. The experience of University Hospital as a centre for cleft patients is discussed.

    Introduction: Introduction: The paper explores turnover intention and job satisfaction among healthcare employees of Ministry of Health (MOH) Malaysia. Methods: A nationwide study was carried out in order to identify dimensions of job satisfaction and turnover intention among public healthcare employees. Data was collected by means of self-administered questionnaire and distributed based on quota sampling. Results: The study shows that public healthcare workforce is generally satisfied with their work (mean 3.45). In addition, medical specialists and assistant medical officers were found to be significantly more satisfied than other job designations. However, intention to resign was high among medical specialists, pharmacists and dentists. A high proportion of medical specialists also had received job offers from the private sector. Conclusion: The findings showed that employee turnover may not necessarily be due to job dissatisfaction, but rather due to demand from the private sector. Findings from the study would assist policy-makers with respect to talent management in public healthcare service.

    Anaemia is the most common haematological problem in the elderly population. Using WHO criteria for anaemia (Hb of <12 g/dL in women and <13 g/dL in men), the prevalence of anaemia in the elderly has been found to range from 8-44% with the highest prevalence in men 85 years and older. Anaemia must not be considered simply as part of ageing because in 80% of cases, there is an underlying cause for Hb
    levels of <12 g/dL in the elderly. Anaemia has negative impacts on the quality of life for the elderly and there is evidence of improved morbidity and
    mortality after correction of anaemia. Chronic disease and thalassaemia may also cause microcytic anaemia besides iron deficiency and not all vitamin B12 and folate deficiency present with macrocytic megaloblastic anaemia. Nutritional deficiency anaemias are common, easily diagnosed, treatments are simple, inexpensive and effective. Tests for nutritional anaemia have to be given priority in the assessment before a patient is subjected to invasive tests to look for less common causes of anaemia. Serum ferritin which is the best non-invasive test for the diagnosis of iron deficiency anaemia may be increased in the elderly while serum iron and transferrin decrease with ageing. Serum methylmalonic acid (MMA) and homocysteine (HC) levels are sensitive for detecting subclinical vitamin B12 and folate deficiency. Routine iron therapy in non-anaemic elderly or in those without iron deficiency anaemia is of no use and may be detrimental to their health. Folate therapy may improve anaemia but may mask the signs and symptoms of neurological damage due to concomitant
    vitamin B12 deficiency. Blood transfusion offers prompt symptom relief of anaemia in patients with terminal malignancy irrespective of the causes for the anaemia.

    Employee motivation affects productivity and need to be channeled towards the accomplishment of organizational goals. A cross sectional study was conducted among Public Health Specialists (PHS) in the Ministry of Health Malaysia to study their motivation level and the factors influencing this. The respondents were from the Association of Public Health Specialists of Malaysia working in the Ministry of Health. Quantitative Technique self-administered questionnaires were used in this study and the questionnaires were mailed to the respondents. The response rate for this study was 72.3%. In measuring the motivation level, five (5) aspects were studied. The social aspect, self -achievement aspect and autonomy aspect were found to be the main aspects that motivated the respondents. With regard to motivation level, 55.8 % respondents had low motivation level. In order to improve the motivation level among PHS, the aspect of self actualization and autonomy required serious attention. In the future, PHS are expected to play a major role in controlling, promoting, preventing, maintaining, restoring and solving problems in order to enhance the health of the Malaysian population.

    BACKGROUND: The College of General Practitioners of Malaysia and the Royal Australian College of General Practitioners held the first Conjoint Member of the College of General Practitioners (MCGP)/Fellow of Royal Australian College of General Practitioners (FRACGP) examination in 1982, later renamed the Conjoint MAFP/FRACGP examinations. The examination assesses competency for safe independent general practice and as family medicine specialists in Malaysia. Therefore, a defensible standard set pass mark is imperative to separate the competent from the incompetent.

    OBJECTIVE: This paper discusses the process and issues encountered in implementing standard setting to the Conjoint Part 1 examination.

    DISCUSSION: Critical to success in standard setting were judges' understanding of the process of the modified Angoff method, defining the borderline candidate's characteristics and the composition of judges. These were overcome by repeated hands-on training, provision of detailed guidelines and careful selection of judges. In December 2013, 16 judges successfully standard set the Part 1 Conjoint examinations, with high inter-rater reliability: Cronbach's alpha coefficient 0.926 (Applied Knowledge Test), 0.921 (Key Feature Problems).

    BACKGROUND: Cataract surgery is associated with a variety of complications, one of which is vitreous loss. Doctors and policymakers should be aware about the precipitating factors, associations, and expected outcomes of vitreous loss. This study was, therefore, undertaken to set guidelines to improve the visual outcomes of patients.

    MATERIALS AND METHODS: A retrospective 8-year analysis was conducted from 2007 to 2014 using the national eye database. Demographic features, ocular comorbidities, grade of surgeon, type of surgery, and the associations with the occurrence of vitreous loss, and the final visual outcomes of these patients were studied.

    RESULTS: Out of 12,992 eyes, only 3.2% had vitreous loss, mostly aged <40 years. Pseudoexfoliation was the only ocular comorbidity causing vitreous loss. Medical Officers and Gazetting Specialists got more vitreous loss compared to specialists. Intracapsular cataract extraction, phaco convert to extracapsular cataract extraction (ECCE), ECCE, and phaco all had a significant vitreous loss. Vitreous loss was the most significant intraoperative complication causing poor vision and resulted in impaired or poor visual outcome.

    CONCLUSION: Vitreous loss occurred in almost all types of cataract surgeries, especially by junior surgeons, among those aged <40 years and significantly caused poor visual outcome compared to other complications. Pseudoexfoliation had higher occurrence of vitreous loss. Vitreous loss patients had impaired/poor visual outcome due to preexisting comorbidity and astigmatism. Patients at risk and junior surgeons should be closely monitored to improve outcomes. Further studies need to be done to see why and when the vitreous loss occurred.

    INTRODUCTION: Specialists constitute a major 'driving force' and catalyst for growth of research in their speciality. A clearer understanding is required as to what motivates their participation in research as well as the barriers they faced. This research aims to study the attitudes, barriers and facilitators faced by specialists and to identify strategies to promote and sustain research activities in their hospitals.

    METHODOLOGY: A cross-sectional survey using selfadministered questionnaires was conducted among all specialists working in government specialist hospitals in the northern states of Malaysia.

    RESULTS: Out of 733 questionnaires distributed, 467 were returned giving a response rate of 63.7%. Ninety-nine percent of the respondents believed that research benefits patients while 93.3% think research helps in their professional development. However, 34.8% think that under their present working conditions, it is unlikely they will participate in research. The major barriers identified were lack of funds for research (81%); lack access to expertise, software or statistical analysis (78.4%); interference with daily work schedule (75.1%) and inconsistent manpower in their department (74.2%). There are three barriers with statistically significant difference between hospitals with CRC compared to hospitals without CRC; lack of funds, mentors and access to expertise, software or statistical analysis. The demographic factors, attitudes and barriers contributing to involvement in research also investigated. The main facilitators for the conduct of research are potential to benefit patients and potential for professional development.

    CONCLUSION: Taking note of the findings, the Ministry of Health can implement appropriate strategies to improve specialist participation in research.

    congenital deformity among paediatric patients. The outcome of starting clubfoot treatment early is very
    promising. Patient retention throughout the treatment programme is challenging in Sarawak. In this study,
    we explored the barriers that parents/caregivers face when seeking clubfoot treatment in Sarawak, Northwest
    Borneo. A better understanding of the barriers will provide us with the information to formulate effective
    programmes for clubfoot treatment in this region.
    Methods: We conducted a questionnaire-based quantitative cross-sectional descriptive survey. We adapted
    a set of closed-ended questionnaires originally designed by Kazibwe and Struthers in a study done in Uganda
    in the year 2006.
    Results: A total of 53 parents/caregivers of children with idiopathic clubfoot were recruited in this study, with
    16 defaulter cases and 37 non-defaulter cases. We found 2 statistically significant barriers to clubfoot treatment
    in Sarawak, with p-value < 0.05, namely the geographical factor (p = 0.019) and logistic factor (p = 0.017).
    Conclusion: Barriers to clubfoot treatment that influence the compliance to treatment identified in this study
    are long distance travel, logistics limitations, uncooperative patients during treatment, parents/caregivers
    having other commitments, unsupportive family members, lack of understanding regarding clubfoot and its
    treatment, inadequate specialists in clubfoot, traditional socio-cultural beliefs and practices and economic
    constraints. Enhanced understanding in this matter will guide us in devising culturally admissible ways to
    increase awareness in parents/caregivers regarding clubfoot and its treatment. A sustainable national clubfoot
    program will be very beneficial in providing a holistic approach to tackle barriers to treatment in our country.

    Angiography procedures is one of the diagnostic imaging procedures for studying blood vessels in the arteries and veins. This angiography examination is performed by injecting a viscous liquid called contrast media into the blood vessels to clearly identify the blocked blood vessels. This procedure involves the exposure of X-Ray in certain blood vessels and is performed by the Interventionist Radiologist. There are several types of angiography examinations which include cerebral angiography, coronary angiography, pulmonary angiography, peripheral angiography and renal angiography. The main problem that occurs during the Lower Limb Angiography examination involving elderly patients aged 60 years and above who suffer from critical diabetes stage in both blood vessels. The problem arise when there is no special immobilize device to support the foot and the patients were in an uncomfortable state for a period of 2-3 hours during the examination. Hence specialists had difficulty to interpret accurately the blood vessel clot in the foot due to less optimum radiograph. IMMOLIMBTM is an innovative invention created from used waste to overcome the foot movements, providing comfort and enhancing optimum diagnostic images.

    Background and objective: A successful family physician program needs ongoing and full cooperation between people and the organizations in charge. Ensuring the satisfaction of family physicians through improvement of the underlying factors could motivate them to provide high-quality services. This study aimed to determine the family physicians' satisfaction level with the factors affecting the dynamism of the urban family physicians program in the Fars and Mazandaran provinces of Iran.

    Method: This cross-sectional study was carried out in urban areas in the Fars and Mazandaran provinces in 2016. The sample consisted of 143 and 96 family physicians, respectively, in Fars and Mazandaran provinces and was selected using the stratified random sampling method. Data were collected using a questionnaire and included both sociodemographic variables and factors assessing the family physicians' satisfaction levels. Each factor was scored based on a Likert scale from 0 to 5 points, and any satisfaction level higher than 3 out of 5 was equated with being satisfied.

    Results: The overall satisfaction levels among family physicians in Fars and Mazandaran provinces were 2.77±0.53 and 3.37±0.56, respectively, revealing a statistically significant difference between provinces (p<0.001). Moreover, the mean satisfaction scores for the performances of healthcare centers, insurance companies, specialists, healthcare workers, and the population covered were 2.78±0.1, 2.54±0.9, 2.52±0.8, 4.24±0.07, and 2.96±0.8, respectively. The family physicians' levels of satisfaction were significantly correlated with population size (p=0.02, r= -0.106), and willingness to stay in an urban family physician program (p<0.001, r= +0.398).

    Conclusion: This study revealed that family physicians exhibited a low level of satisfaction with the urban family physician program. Given the direct association between family physicians' satisfaction levels and retention in the program, it is expected that family physicians will no longer stay in the program, and it is likely to have subsequent executive problems.

    Introduction: This study aimed to determine the views and practices of healthcare providers and barriers they encountered when implementing the national health screening program for men in a public primary care setting in Malaysia.

    Methods: An online survey was conducted among healthcare providers across public health clinics in Malaysia. All family medicine specialists, medical officers, nurses and assistant medical officers involved in the screening program for adult men were invited to answer a 51-item questionnaire via email or WhatsApp. The questionnaire comprised five sections: participants' socio-demographic information, current screening practices, barriers and facilitators to using the screening tool, and views on the content and format of the screening tool.

    Results: A total of 231 healthcare providers from 129 health clinics participated in this survey. Among them, 37.44% perceived the implementation of the screening program as a "top-down decision." Although 37.44% found the screening tool for adult men "useful," some felt that it was "time consuming" to fill out (38.2%) and "lengthy" (28.3%). In addition, 'adult men refuse to answer' (24.1%) was cited as the most common patient-related barrier.

    Conclusions: This study provided useful insights into the challenges encountered by the public healthcare providers when implementing a national screening program for men. The screening tool for adult men should be revised to make it more user-friendly. Further studies should explore the reasons why men were reluctant to participate in health screenings, thus enhancing the implementation of screening programs in primary care.

    Because anti-tumor necrosis factor (anti-TNF) therapy has become increasingly popular in many Asian countries, the risk of developing active tuberculosis (TB) among anti-TNF users may raise serious health problems in this region. Thus, the Asian Organization for Crohn's and Colitis and the Asia Pacific Association of Gastroenterology have developed a set of consensus statements about risk assessment, detection and prevention of latent TB infection, and management of active TB infection in patients with inflammatory bowel disease (IBD) receiving anti-TNF treatment. Twenty-three consensus statements were initially drafted and then discussed by the committee members. The quality of evidence and the strength of recommendations were assessed by using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Web-based consensus voting was performed by 211 IBD specialists from 9 Asian countries concerning each statement. A consensus statement was accepted if at least 75% of the participants agreed. Part 2 of the statements comprised 3 parts: management of latent TB in preparation for anti-TNF therapy, monitoring during anti-TNF therapy, and management of an active TB infection after anti-TNF therapy. These consensus statements will help clinicians optimize patient outcomes by reducing the morbidity and mortality related to TB infections in patients with IBD receiving anti-TNF treatment.

    Plants play a crucial role in foodstuff, medicine, industry, and environmental protection. The skill of recognising plants is very important in some applications, including conservation of endangered species and rehabilitation of lands after mining activities. However, it is a difficult task to identify plant species because it requires specialized knowledge. Developing an automated classification system for plant species is necessary and valuable since it can help specialists as well as the public in identifying plant species easily. Shape descriptors were applied on the myDAUN dataset that contains 45 tropical shrub species collected from the University of Malaya (UM), Malaysia. Based on literature review, this is the first study in the development of tropical shrub species image dataset and classification using a hybrid of leaf shape and machine learning approach. Four types of shape descriptors were used in this study namely morphological shape descriptors (MSD), Histogram of Oriented Gradients (HOG), Hu invariant moments (Hu) and Zernike moments (ZM). Single descriptor, as well as the combination of hybrid descriptors were tested and compared. The tropical shrub species are classified using six different classifiers, which are artificial neural network (ANN), random forest (RF), support vector machine (SVM), k-nearest neighbour (k-NN), linear discriminant analysis (LDA) and directed acyclic graph multiclass least squares twin support vector machine (DAG MLSTSVM). In addition, three types of feature selection methods were tested in the myDAUN dataset, Relief, Correlation-based feature selection (CFS) and Pearson's coefficient correlation (PCC). The well-known Flavia dataset and Swedish Leaf dataset were used as the validation dataset on the proposed methods. The results showed that the hybrid of all descriptors of ANN outperformed the other classifiers with an average classification accuracy of 98.23% for the myDAUN dataset, 95.25% for the Flavia dataset and 99.89% for the Swedish Leaf dataset. In addition, the Relief feature selection method achieved the highest classification accuracy of 98.13% after 80 (or 60%) of the original features were reduced, from 133 to 53 descriptors in the myDAUN dataset with the reduction in computational time. Subsequently, the hybridisation of four descriptors gave the best results compared to others. It is proven that the combination MSD and HOG were good enough for tropical shrubs species classification. Hu and ZM descriptors also improved the accuracy in tropical shrubs species classification in terms of invariant to translation, rotation and scale. ANN outperformed the others for tropical shrub species classification in this study. Feature selection methods can be used in the classification of tropical shrub species, as the comparable results could be obtained with the reduced descriptors and reduced in computational time and cost.

    During the Coronavirus Disease 2019 (COVID-19) pandemic, practices of gastrointestinal procedures within the digestive tract require special precautions due to the risk of contraction of severe acute respiratoy syndrome coronavirus-2 (SARS-CoV-2) infection. Many procedures in the gastrointestinal motility laboratory may be considered moderate to high-risk for viral transmission. Healthcare staff working in gastrointestinal motility laboratories are frequently exposed to splashes, air droplets, mucus, or saliva during the procedures. Moreover, some are aerosol-generating and thus have a high risk of viral transmission. There are multiple guidelines on the practices of gastrointestinal endoscopy during this pandemic. However, such guidelines are still lacking and urgently needed for the practice of gastrointestinal motility laboratories. Hence, the Asian Neurogastroenterology and Motility Association had organized a group of gastrointestinal motility experts and infectious disease specialists to produce a position statement paper based-on current available evidence and consensus opinion with aims to provide a clear guidance on the practices of gastrointestinal motility laboratories during the COVID-19 pandemic. This guideline covers a wide range of topics on gastrointestinal motility activities from scheduling a motility test, the precautions at different steps of the procedure to disinfection for the safety and well-being of the patients and the healthcare workers. These practices may vary in different countries depending on the stages of the pandemic, local or institutional policy, and the availability of healthcare resources. This guideline is useful when the transmission rate of SARS-CoV-2 is high. It may change rapidly depending on the situation of the epidemic and when new evidence becomes available.
