    The present study was aimed to assess the diversity of influenza A viruses (IAV) circulating in pig farms in the Iberian Peninsula. The study included two different situations: farms suffering respiratory disease outbreaks compatible with IAV (n = 211) and randomly selected farms without overt respiratory disease (n = 19). Initially, the presence of IAV and lineage determination was assessed by qRT-PCR using nasal swabs. IAV was confirmed in 145 outbreaks (68.7%), mostly in nurseries (53/145; 36.5%). Subtyping by RT-qPCR was possible in 94 of those cases being H1avN2hu (33.6%), H1avN1av (24.3%) and H1huN2hu (18.7%), the most common lineages. H3huN2hu and H1pdmN1pdm represented 7.5% and 6.5% of the cases, respectively. As for the randomly selected farms, 15/19 (78.9%) were positive for IAV. Again, the virus was mostly found in nurseries and H1avN2hu was the predominant lineage. Virus isolation in MDCK cells was attempted from positive cases. Sixty of the isolates were fully sequenced with Illumina MiSeq®. Within those 60 isolates, the most frequent genotypes had internal genes of avian origin, and these were D (19/60; 31.7%) and A (11/60; 18.3%), H1avN2hu and H1avN1av, respectively. In addition, seven previously unreported genotypes were identified. In two samples, more than one H or N were found and it was not possible to precisely establish their genotypes. A great diversity was observed in the phylogenetic analysis. Notably, four H3 sequences clustered with human isolates from 2004-05 (Malaysia and Denmark) that were considered uncommon in pigs. Overall, this study indicates that IAV is a very common agent in respiratory disease outbreaks in Spanish pig farms. The genetic diversity of this virus is continuously expanding with clear changes in the predominant subtypes and lineages in relatively short periods of time. The current genotyping scheme has to be enlarged to include the new genotypes that could be found in the future.

    OBJECTIVE: To evaluate the association between intakes of refined grains, whole grains, and white rice with cardiovascular disease, total mortality, blood lipids, and blood pressure in the Prospective Urban and Rural Epidemiology (PURE) study.

    DESIGN: Prospective cohort study.

    SETTING: PURE study in 21 countries.

    PARTICIPANTS: 148 858 participants with median follow-up of 9.5 years.

    EXPOSURES: Country specific validated food frequency questionnaires were used to assess intakes of refined grains, whole grains, and white rice.

    MAIN OUTCOME MEASURE: Composite of mortality or major cardiovascular events (defined as death from cardiovascular causes, non-fatal myocardial infarction, stroke, or heart failure). Hazard ratios were estimated for associations of grain intakes with mortality, major cardiovascular events, and their composite by using multivariable Cox frailty models with random intercepts to account for clustering by centre.

    RESULTS: Analyses were based on 137 130 participants after exclusion of those with baseline cardiovascular disease. During follow-up, 9.2% (n=12 668) of these participants had a composite outcome event. The highest category of intake of refined grains (≥350 g/day or about 7 servings/day) was associated with higher risk of total mortality (hazard ratio 1.27, 95% confidence interval 1.11 to 1.46; P for trend=0.004), major cardiovascular disease events (1.33, 1.16 to 1.52; P for trend<0.001), and their composite (1.28, 1.15 to 1.42; P for trend<0.001) compared with the lowest category of intake (<50 g/day). Higher intakes of refined grains were associated with higher systolic blood pressure. No significant associations were found between intakes of whole grains or white rice and health outcomes.

    CONCLUSION: High intake of refined grains was associated with higher risk of mortality and major cardiovascular disease events. Globally, lower consumption of refined grains should be considered.

    Cannibalism is a major problem in lobster and crab aquaculture. Reducing the aggressive characteristics of lobsters and crabs can improve survival during the culturing process. In this study, juvenile scalloped spiny lobsters (Panulirus homarus) and crucifix crabs (Charybdis feriatus) were both cultured under different shelter and live prey conditions. Groups with shelter (seaweed and cotton filter) showed a better survival rate than the control group (no shelter; p < 0.05) for both Pa. homarus and Char. feriatus. Co-culturing with live prey (Litopenaeus vannamei) significantly benefited the juveniles of Pa. homarus and visibly increased the survival of juvenile Char. feriatus. Although providing shelter is currently the main method for reducing agonistic behavior, it must be continually altered as the lobsters and crabs grow. Live prey can grow and attract lobsters and crabs to hunt them, and live prey can be supplemented at any time. They can also be used as an additional source of income during the harvest season.

    BACKGROUND: The COVID-19 pandemic has had a profound global impact on governments, health care systems, economies, and populations around the world. Within the East Asia and Pacific region, some countries have mitigated the spread of the novel coronavirus effectively and largely avoided severe negative consequences, while others still struggle with containment. As the second wave reaches East Asia and the Pacific, it becomes more evident that additional SARS-CoV-2 surveillance is needed to track recent shifts, rates of increase, and persistence associated with the pandemic.

    OBJECTIVE: The goal of this study is to provide advanced surveillance metrics for COVID-19 transmission that account for speed, acceleration, jerk, persistence, and weekly shifts, to better understand country risk for explosive growth and those countries who are managing the pandemic successfully. Existing surveillance coupled with our dynamic metrics of transmission will inform health policy to control the COVID-19 pandemic until an effective vaccine is developed. We provide novel indicators to measure disease transmission.

    METHODS: Using a longitudinal trend analysis study design, we extracted 330 days of COVID-19 data from public health registries. We used an empirical difference equation to measure the daily number of cases in East Asia and the Pacific as a function of the prior number of cases, the level of testing, and weekly shift variables based on a dynamic panel model that was estimated using the generalized method of moments approach by implementing the Arellano-Bond estimator in R.

    RESULTS: The standard surveillance metrics for Indonesia, the Philippines, and Myanmar were concerning as they had the largest new caseloads at 4301, 2588, and 1387, respectively. When looking at the acceleration of new COVID-19 infections, we found that French Polynesia, Malaysia, and the Philippines had rates at 3.17, 0.22, and 0.06 per 100,000. These three countries also ranked highest in terms of jerk at 15.45, 0.10, and 0.04, respectively.

    CONCLUSIONS: Two of the most populous countries in East Asia and the Pacific, Indonesia and the Philippines, have alarming surveillance metrics. These two countries rank highest in new infections in the region. The highest rates of speed, acceleration, and positive upwards jerk belong to French Polynesia, Malaysia, and the Philippines, and may result in explosive growth. While all countries in East Asia and the Pacific need to be cautious about reopening their countries since outbreaks are likely to occur in the second wave of COVID-19, the country of greatest concern is the Philippines. Based on standard and enhanced surveillance, the Philippines has not gained control of the COVID-19 epidemic, which is particularly troubling because the country ranks 4th in population in the region. Without extreme and rigid social distancing, quarantines, hygiene, and masking to reverse trends, the Philippines will remain on the global top 5 list of worst COVID-19 outbreaks resulting in high morbidity and mortality. The second wave will only exacerbate existing conditions and increase COVID-19 transmissions.

    Background and aims: Wildlife conservation has focused primarily on species for the last decades. Recently, popular perception and laws have begun to recognize the central importance of genetic diversity in the conservation of biodiversity. How to incorporate genetic diversity in ongoing monitoring and management of wildlife is still an open question.

    Methods: We tested a panel of multiplexed, high-throughput sequenced introns in the small mammal communities of two UNESCO World Heritage Sites on different continents to assess their viability for large-scale monitoring of genetic variability in a spectrum of diverse species. To enhance applicability across other systems, the bioinformatic pipeline for primer design was outlined.

    Results: The number of loci amplified and amplification evenness decreased as phylogenetic distance increased from the reference taxa, yet several loci were still variable across multiple mammal orders.

    Conclusions: Genetic variability found is informative for population genetic analyses and for addressing phylogeographic and phylogenetic questions, illustrated by small mammal examples here.

    BACKGROUND: The selection of orders is the method of gathering the parts needed to assemble the final products from storage sites. Kitting is the name of a ready-to-use package or a parts kit, flexible robotic systems will significantly help the industry to improve the performance of this activity. In reality, despite some other limitations on the complexity of components and component characteristics, the technological advances in recent years in robotics and artificial intelligence allows the treatment of a wide range of items.

    OBJECTIVE: In this article, we study the robotic kitting system with a Robotic Mounted Rail Arm System (RMRAS), which travels narrowly to choose the elements.

    RESULTS: The objective is to evaluate the efficiency of a robotic kitting system in cycle times through modeling of the elementary kitting operations that the robot performs (pick and room, move, change tools, etc.). The experimental results show that the proposed method enhances the performance and efficiency ratio when compared to other existing methods.

    CONCLUSION: This study with the manufacturer can help him assess the robotic area performance in a given design (layout and picking a policy, etc.) as part of an ongoing project on automation of kitting operations.

    Bronchopulmonary dysplasia (BPD) is a devastating lung disorder of preterm infants as a result of an aberrant reparative response following exposures to various antenatal and postnatal insults. Despite sophisticated medical treatment in this modern era, the incidence of BPD remains unabated. The current strategies to prevent and treat BPD have met with limited success. The emergence of stem cell therapy may be a potential breakthrough in mitigating this complex chronic lung disorder. Over the last two decades, the human placenta and umbilical cord have gained increasing attention as a highly potential source of stem cells. Placenta-derived stem cells (PDSCs) and umbilical cord-derived stem cells (UCDSCs) display several advantages such as immune tolerance and are generally devoid of ethical constraints, in addition to their stemness qualities. They possess the characteristics of both embryonic and mesenchymal stromal/stem cells. Recently, there are many preclinical studies investigating the use of these cells as therapeutic agents in neonatal disease models for clinical applications. In this review, we describe the preclinical and clinical studies using PDSCs and UCDSCs as treatment in animal models of BPD. The source of these stem cells, routes of administration, and effects on immunomodulation, inflammation and regeneration in the injured lung are also discussed. Lastly, a brief description summarized the completed and ongoing clinical trials using PDSCs and UCDSCs as therapeutic agents in preventing or treating BPD. Due to the complexity of BPD, the development of a safe and efficient therapeutic agent remains a major challenge to both clinicians and researchers.

    Despite a large amount of research on depression and abuse, there is still a controversy on how abuse is measured and on childhood trauma's effect on the physiological function of adults. Here, we attempt to clarify the relationship between different types of abuse and depression while focusing on childhood abuse. This article, unlike prior research, provides an overview that addresses physical, psychological, and sexual abuse and their psychological impact on the victims. Results show that abuse is a vulnerability factor for a variety of mental and physical health problems and that psychological abuse is strongly associated with depression. More research is needed to understand (a) the role of abuse in the development and maintenance of depression and, in particular, longitudinal studies that also account for the large number of risk and protective factors that influence this relationship and (b) how different types of abuse can influence response to treatment among survivors with depression, in order to provide effective trauma-focused approaches to manage depressive symptoms.

    Purpose: Use of dietary supplements by older adults has been increasing for improving micronutrient deficiencies, cognitive function, and overall health status. Thus, the objective of this secondary investigation is to explore the longitudinal association of baseline supplement intake in improving cognitive function, biochemical parameters, anthropometric variables and physical fitness among older adults.

    Methods: Towards Useful Aging (TUA) is a three-year longitudinal study conducted at baseline (2013-2014) and at follow-up (2015-2017) surveys. The number of participants dropped from 2322 during baseline study to 1787 and 1560 during the 18th and 36th month follow-up, respectively. Data on socio-demography, use of dietary supplement, biochemical indices, anthropometry, cognitive function, physical fitness and depressive symptoms were obtained. Longitudinal associations were done using the linear mixed model analysis among 1285 subjects with complete data.

    Results: The most common vitamin and mineral supplementations consumed were multivitamin, B-complex, and calcium. Meanwhile, the herbal supplements consumed by participants were Eurycoma longifolia, Morinda citrifolia and Orthosiphon aristatus. Longitudinal analysis adjusted for multiple covariates showed improvement in both supplement users and non-users for global cognitive function, working memory, visual memory, 2-minute step test, chair stand test, chair sit and reach and time up and go test, waist circumference and hip circumference in both the supplement users and non-users.

    Conclusion: Our findings indicated that dietary supplement intake is not associated with cognitive function, physical fitness, nutritional status, depressive symptoms or biochemical indices since improvement in the parameters was observed among both supplement users and non-users.

    BACKGROUND: The COVID-19 pandemic prompted movement restrictions in countries worldwide, impacting on physical activity (PA), a major non-communicable disease risk factor, and thus may have unintentional long-term health implications. In semi-rural areas of low-middle-income-countries (LMICs), where occupational activity is the main source of PA, changes in PA associated with COVID-19 restrictions are unknown. We investigated the impact of Movement Control Order (MCO) restrictions in a semi-rural region of Malaysia.

    METHODS: The South East Asia Community Observatory (SEACO) is a dynamic prospective community cohort. We contacted a random sample of 1007 adults (18+) who had previously provided PA data in 2018. We asked about PA during the MCO (March-May 2020) and at the time of interview (June 2020).

    RESULTS: During the MCO, PA reduced by a mean of 6.7 hours/week (95% confidence interval (CI) = 5.3, 8.0) compared to 2018, with the largest reductions among those in employment. By June, PA was 3.4 hours/week (95% CI = 2.0, 4.8) less than 2018, leaving 34% of adults currently inactive (20% in 2018). Reductions in occupational PA were not replaced with active travel or activity at home. Despite these observed reductions, most participants did not think the MCO had affected their PA.

    CONCLUSIONS: Movement restrictions are associated with lower PA lasting beyond the period of strict restrictions; such longer-term reductions in PA may have a detrimental impact on health. Future MCOs should encourage people to be active, but may additionally need targeted messaging for those who don't necessarily realise they are at risk. In particular, policies developed in more affluent countries may not easily translate to LMICs.

    Previous research has found that women at peak fertility show greater interest in extra-pair sex. However, recent replications have failed to detect this effect. In this study, we add to this ongoing debate by testing whether sociosexuality (the willingness to have sex in the absence of commitment) is higher in women who are at peak fertility. A sample of normally ovulating women (N = 773) completed a measure of sociosexuality and had their current fertility status estimated using the backward counting method. Contrary to our hypothesis, current fertility was unrelated to sociosexual attitudes and desires, even when relationship status was included as a moderator. These findings raise further doubts about the association between fertility and desire for extra-pair sex.

    During the initial phase of the COVID-19 pandemic, U.S. conservative politicians and the media downplayed the risk of both contracting COVID-19 and the effectiveness of recommended health behaviors. Health behavior theories suggest perceived vulnerability to a health threat and perceived effectiveness of recommended health-protective behaviors determine motivation to follow recommendations. Accordingly, we predicted that-as a result of politicization of the pandemic-politically conservative Americans would be less likely to enact recommended health-protective behaviors. In two longitudinal studies of U.S. residents, political conservatism was inversely associated with perceived health risk and adoption of health-protective behaviors over time. The effects of political orientation on health-protective behaviors were mediated by perceived risk of infection, perceived severity of infection, and perceived effectiveness of the health-protective behaviors. In a global cross-national analysis, effects were stronger in the U.S. (N = 10,923) than in an international sample (total N = 51,986), highlighting the increased and overt politicization of health behaviors in the U.S.

    BACKGROUND AND AIMS: This online cross-sectional study investigated the severity of depressive, anxiety, and stress symptoms among university students and determined the association between various factors and the levels of depressive and anxiety symptoms in response to the coronavirus disease 2019 (COVID-19) pandemic after the movement control order (MCO) was lifted.

    METHODS: A total of 316 participants were administered a self-report questionnaire that collected data on sociodemographic attributes, personal characteristics, COVID-19-related stressors, religious coping, and clinical characteristics. In addition, the Multidimensional Scale of Perceived Social Support (MSPSS) and the 21-item Depression, Anxiety and Stress Scale (DASS-21) were administered.

    RESULTS: Regarding depression, 15.5%, 11.7%, and 9.2% of the participants reported mild, moderate, and severe to extremely severe depression, respectively. For anxiety, 7.0%, 16.5%, and 13.2% of the respondents had mild, moderate, and severe to extremely severe anxiety, respectively. Moreover, 26.3% of participants had mild stress, 9.5% had moderate stress, and 6.6% had severe to extremely severe stress. The multiple linear regression model revealed that frustration because of loss of daily routine and study disruption and having preexisting medical, depressive, and anxiety disorders were associated with elevated depressive symptoms, while a greater degree of family and friends social support was associated with less depressive symptoms after adjusting for age, gender, and marital status. It was also found that frustration because of study disruption and having preexisting medical, depressive, and anxiety disorders were associated with elevated anxiety symptoms, while being enrolled in medicine-based courses and having a greater degree of family support were factors associated with less anxiety symptoms after adjusting for age, gender, and marital status.

    CONCLUSION: There is a need to conduct a longitudinal study in the future to confirm the causal relationship between the significant predictive factors and depression and anxiety identified in this study, and maintenance of a persistent flow of academic activities and social interaction may be of utmost importance to safeguard the mental wellbeing of university students.

    PURPOSE: Older persons have been identified as a vulnerable population with respect to the novel coronavirus outbreak, COVID-19. Aiming to "flatten the curve" a strict Movement Control Order (MCO) was implemented in Malaysia. Older adults with cognitive frailty are prone to physical, cognitive and psychosocial decline. This study aims to compare physical activity patterns, psychological wellbeing and coping strategies of older persons with cognitive frailty in the "WE-RISE" trial (intervention versus control) throughout this period.

    MATERIALS AND METHODS: This study was conducted as a sub-analysis of the ongoing "WE-RISE" randomized controlled trial. This study included 42 community-dwelling older adults, aged 60 years and above, with cognitive frailty, stratified into intervention (n=21) and control (n=21) groups who are receiving a multi-domain intervention and usual care, respectively, within the Klang Valley, Malaysia. Phone call interviews were conducted during the MCO period. Physical activity patterns were assessed using International Physical Activity Questionnaire (IPAQ) and Functional Activities Questionnaire (FAQ). Psychological wellbeing was assessed using Flourishing Scale (FS) and General Health Questionnaire (GHQ-12), while the Brief Coping Orientation to Problems Experienced (COPE) assessed coping strategies. Data were analysed descriptively and with independent samples t-test.

    RESULTS: The WE-RISE intervention group had significantly higher levels of estimated resting energy expenditure (MET) for "walking activity" (I:μ=1723.1±780.7;C:μ=537.4±581.9)(p<0.001), "moderate activity" (I:μ=1422.8±1215.1;C:μ=405.7±746.9)(p=0.002) and "total physical activity" (I: μ=3625.9±3399.3;C:μ=994.6±1193.9)(p=0.002). The intervention group was also significantly more independent in functional activities (μ=1.76±1.73) as compared to the control group (μ=5.57±8.31) (p<0.05). Moreover, significant higher self-perception of living a meaningful life and feeling respected (p<0.05) was demonstrated in regard to psychological well-being in the intervention group. Regarding coping strategies, the intervention group relied significantly on the domains of religion (I:μ=6.43±0.99;C:μ=6.09±1.09)(p<0.05) and planning (I:μ=4.81±0.75; C:μ=4.04±1.28)(p<0.05) whilst the control group relied on humour (C:μ=3.14±1.19; I:μ=2.38±0.74)(p<0.05).

    CONCLUSION: Participants of the WE-RISE intervention group were more physically active, functionally independent and had higher self-perceived social-psychological prosperity regarding living a meaningful life and feeling respected; whilst both groups relied on positive coping strategies during the MCO. These results indicate that it is vital to ensure older persons with cognitive frailty remain physically active and preserve their psychosocial wellbeing to be more resilient in preventing further decline during a crisis such as the COVID-19 pandemic.

    Low vision and blindness are major health issues affecting ageing population. This cross-sectional study aims to determine the prevalence of visual impairment (VI) in Petaling Jaya North, Petaling Jaya South, and Lembah Pantai using data from the Malaysian Elders Longitudinal Research. There were 1322 participants aged ≥55 years selected by random sampling from parliamentary electoral rolls. Visual acuity was assessed using the logarithm of the minimum angle of resolution chart at 4 m distance. The overall population-adjusted prevalence of VI was 9.0%. The estimated prevalence of VI was highest in Malays followed by Indians and Chinese. Following adjustments for ethnic discrepancies in age, marital status, education level, gender and medical illness, the Malay ethnicity remained an independent association for VI. Education level was associated with Indian ethnicity. In conclusion, the Malay ethnicity and lower education level among Indian ethnicity were found to be associated with VI among the older population in Malaysia. The Malay ethnicity showed the highest prevalence of VI followed by Indians and Chinese.

    Food safety issues associated with aquatic food products become more important with the increasing consumption and followed by its ongoing challenges. The objective of this paper is to review the food safety hazards and health risks related to aquatic food products for the Southeast Asian region. These hazards can be categorized as microplastics (MPs) hazard, biological hazards (pathogenic bacteria, biogenic amines, viruses, parasites), and chemical hazards (antimicrobial, formaldehyde, heavy metal). In different Southeast Asian countries, the potential health risks of aquatic food products brought by food hazards to consumers were at different intensity and classes. Among all these hazards, pathogenic bacteria, antimicrobials, and heavy metal were a particular concern in the Southeast Asian region. With environmental changes, evolving consumption patterns, and the globalization of trade, new food safety challenges are created, which put forward higher requirements on food technologies, food safety regulations, and international cooperation.

    The longitudinal relationship between muscle strength, dietary intake and physical activity among adolescents is not well understood. We investigated the trend and longitudinal effects of dietary intakes and physical activity scores on muscle strength in adolescents. This prospective cohort study consisted of 436 adolescents (134 males; 302 females) aged 13 years at baseline (2012) who were followed up at the ages of 15 (2014) and 17 (2016) years, respectively. We measured muscle strength using a calibrated hand dynamometer, estimated dietary intake with a 7-d dietary history and physical activity scores with a validated physical activity questionnaire for older children. A generalised estimating equation was used to examine the effect of dietary intakes and physical activity on muscle strength changes. The analysis was performed separately by sex. The muscle strength for males and females had increased within the 5-year period. The dietary intakes (energy and macronutrients) also increased initially but plateaued after the age of 15 years for both sexes. Females recorded a significant declining trend in physical activity scores compared with males as they grew older. A significant positive longitudinal relationship was found between protein (β = 0·035; P = 0·016), carbohydrate intake (β = 0·002; P = 0·013) and muscle strength among males. However, no longitudinal relationship was found between dietary intake, physical activity and muscle strength among females. Higher protein and carbohydrate intake among males was associated with higher muscle strength but was not observed in females. Nutrition and physical activity focusing on strength building are required in early adolescence and need to be tailored to males and females accordingly.

    Background : Sinus of Valsalva aneurysm (SoVA) is a rare anomaly and can be divided into acquired and congenital forms, the latter being commonly associated with ventricular septal defects (VSDs). Rupture is a catastrophic complication with high mortality without urgent surgical intervention. We would like to highlight the use of echocardiography in an emergency setting for diagnosis and surgical intervention in a critically ill patient.

    Case summary : We report a 27-year-old female with history of conservatively managed VSD known since childhood. She presented with acute decompensated cardiac failure requiring intubation and inotropic support. Bedside echocardiography performed in the emergency department suggested a ruptured SoVA at the right coronary cusp with underlying supracristal VSD. Despite the patient being critically ill with multi-organ failure, surgery was performed as it was the patient's best chance for survival. Intraoperative findings tallied with the early echocardiographic results. She recovered gradually and was eventually discharged despite a stormy post-operative period.

    Discussion : This case report highlights the importance of prompt recognition of SoVA rupture by using bedside echocardiography. Surgical intervention needs to be early despite ongoing sepsis in view of acute mechanical failure. This case was unique as it illustrates a successful management of an acutely ill patient with multi-organ failure through early diagnosis, intensive perioperative stabilization, and surgical intervention.

    Hepatic steatosis is increasingly common and has been implicated in progression of liver fibrosis in chronic hepatitis B (CHB) patients. We aimed to investigate the impact of hepatic steatosis on liver fibrosis and clinical outcomes in CHB patients. Consecutive CHB patients who underwent transient elastography between 2013 and 2017 at a tertiary hospital were included in this longitudinal cohort study. Presence of hepatic steatosis was defined as controlled attenuation parameter, CAP ≥ 248 dB/m, while advanced liver fibrosis was defined as liver stiffness measurement, LSM ≥ 9.4 kPa. Cardiovascular events, liver-related complications, malignancy and mortality and a composite of these outcomes were evaluated with Kaplan-Meier analysis and Cox proportional hazards regression. Our study cohort included 614 patients with median follow-up of 45 (32-63) months. Hepatic steatosis was present in 294 patients (47.9%), and advanced liver fibrosis was present in 127 patients (21.0%). Presence of hepatic steatosis (OR: 1.956, 95% CI: 1.250-3.060) and diabetes mellitus (OR: 3.507, 95% CI: 2.069-5.944) was independently associated with advanced fibrosis. Advanced fibrosis was independently associated with composite outcome (HR: 2.496, 95% CI: 1.352-4.606), liver-related complications (HR: 3.765, 95% CI: 1.380-10.271) and mortality (HR: 3.632, 95% CI: 1.342-9.826), but not cardiovascular events and malignancy. Hepatic steatosis was not associated with any adverse outcomes. We conclude that hepatic steatosis is common and associated with advanced fibrosis in CHB patients. Unlike advanced fibrosis, hepatic steatosis does not predict adverse outcomes in CHB patients.

    A preparatory framework called EASI (Evaluate, Align, Student-centred, Implement and Improve) was developed with the aim of creating awareness about interim options and implementation opportunities for online Clinical and Communication Skills (CCS) learning. The framework, when applied requires faculty to evaluate current resources, align sessions to learning outcomes with student-centred approaches and to continuously improve based on implementation experiences. Using the framework, we were able to generate various types of online CCS learning sessions for implementation in a short period of time due to the recent Covid-19 pandemic. Importantly we learnt a few lessons post-implementation from both students and faculty perspective that will be used for planning and delivery of future sessions. In summary, the framework was useful for creating or redesigning CCS sessions which were disrupted during the pandemic, however post-implementation experience suggests the framework can also be used for future solutions in online CCS learning as healthcare systems and delivery are increasingly decentralised and widely distributed.
