Published: March 2020

ObjectivesThe aim of this review is to summarise the latest evidence on efficacy and safety of treatments for new-onset atrial fibrillation (NOAF) in critical illness.ParticipantsCritically ill adult patients who developed NOAF during admission.Primary and secondary outcomesPrimary outcomes were efficacy in achieving rate or rhythm control, as defined in each study. Secondary outcomes included mortality, stroke, bleeding and adverse events.MethodsWe searched MEDLINE, EMBASE and Web of Knowledge on 11 March 2019 to identify randomised controlled trials (RCTs) and observational studies reporting treatment efficacy for NOAF in critically ill patients. Data were extracted, and quality assessment was performed using the Cochrane Risk of Bias Tool, and an adapted Newcastle-Ottawa Scale.ResultsOf 1406 studies identified, 16 remained after full-text screening including two RCTs. Study quality was generally low due to a lack of randomisation, absence of blinding and small cohorts. Amiodarone was the most commonly studied agent (10 studies), followed by beta-blockers (8), calcium channel blockers (6) and magnesium (3). Rates of successful rhythm control using amiodarone varied from 30.0% to 95.2%, beta-blockers from 31.8% to 92.3%, calcium channel blockers from 30.0% to 87.1% and magnesium from 55.2% to 77.8%. Adverse effects of treatment were rarely reported (five studies).ConclusionThe reported efficacy of beta-blockers, calcium channel blockers, magnesium and amiodarone for achieving rhythm control was highly varied. As there is currently significant variation in how NOAF is managed in critically ill patients, we recommend future research focuses on comparing the efficacy and safety of amiodarone, beta-blockers and magnesium. Further research is needed to inform the decision surrounding anticoagulant use in this patient group.

Published: March 2020

IntroductionClinical practice guidelines (CPGs) are designed to reduce inappropriate clinical variation and improve the quality of care. Barriers to CPGs include a lack of awareness of CPGs, access to them, time pressures and concerns regarding the evidence underpinning CPG development, implementation and dissemination. The objectives of this study are to assess clinicians’ attitudes to CPGs for cancer treatment and the perceived barriers to and facilitators of CPG adherence in order to inform the implementation of cancer treatment CPGs.Methods and analysisA mixed methods study will be conducted using a three-phase, sequential design, with each phase informing the next. In phase 1, a qualitative study using recorded interviews will investigate clinicians’ attitudes to CPGs for cancer treatment and perceptions of barriers and facilitators to CPG adherence (n=30); interview transcripts will be analysed thematically. In phase 2, a survey will quantify the frequency of attitudes, barriers and facilitators identified in phase 1, in a broader clinical sample (n=200). In phase 3, a workshop forum will be held to facilitate discussions examining the implications of phase 1 and 2 findings for cancer CPG implementation strategies (n=40) leading to recommendations for improvements to practice. The workshop discussion will be recorded, and the transcript will be analysed thematically.Ethics and disseminationThis study has received ethics approval in New South Wales, Australia (2019/ETH11722, #52019568810127). Study findings will be published in peer-reviewed journals and will form part of a doctoral thesis and be presented at national and international conferences.

Published: March 2020

ObjectiveThis metaresearch of the clinicaltrials.gov database aims to evaluate how clinical research on palliative care is conducted within the setting of advanced cancer.MethodsClinicaltrials.gov was searched to identify registered studies recruiting patients with cancer, and investigating issues relevant to palliative care. The European Organisation for Research and Treatment of Cancer QLQ-C15-PAL (Quality of Life in palliative cancer care patients) questionnaire was taken into account to define the research domains of interest. Studies investigating cancer-directed therapy, management of cancer treatment-related adverse events and diagnostic tests were excluded. Publication status was crosschecked using PubMed.ResultsOf 3950 identified studies, 514 were included. The most frequent reason for exclusion was cancer-directed therapy (2491). In 2007–2012, 161 studies were registered versus 245 in 2013–2018. Included studies were interventional (84%) or observational (16%). Most studies were monocentric (60%), sponsored by academia (79%), and conducted in North America (57%) or Europe (25%). Seventy-nine per cent of studies evaluated a heterogeneous population (>1 tumour type). Interventional studies most frequently investigated systemic drugs (34%), behavioural interventions (29%) and procedures for pain (24%). Pain, quality of life and physical function were the most frequently studied research domains (188, 95 and 52 studies, respectively). The most applied primary outcome measures were efficacy/symptom control (61%), quality of life (14%) and feasibility (12%). Only 16% of the closed studies had published results in PubMed.ConclusionsOur study describes the heterogeneous landscape of studies conducted to address the issues of patients with advanced cancer in palliative care. Albeit the observed increase in the number of studies over the last decade, the generalisation of the results brought by the existing trials is limited due to methodological issues and lack of reporting. A greater effort is needed to improve clinical research that supports evidence-based palliative cancer care.
Detecting and Shadows in the HSV Color Space Using Dynamic Thresholds

Published: March 2020

The detection of moving objects in a video sequence is an essential step in almost all the systems of vision by computer. However, because of the dynamic change in natural scenes, the detection of movement becomes a more difficult task. In this work, we propose a new method for the detection moving objects that is robust to shadows, noise and illumination changes. For this purpose, the detection phase of the proposed method is an adaptation of the MOG approach where the foreground is extracted by considering the HSV color space. To allow the method not to take shadows into consideration during the detection process, we developed a new shade removal technique based on a dynamic thresholding of detected pixels of the foreground. The calculation model of the threshold is established by two statistical analysis tools that take into account the degree of the shadow in the scene and the robustness to noise. Experiments undertaken on a set of video sequences showed that the method put forward provides better results compared to existing methods that are limited to using static thresholds.
Conceptualizing Information Technology Governance Model for Higher Education: An Absorptive Capacity Approach
Authors: Adeniyi Ajayi Binyamin , Hussin Husnayati 
Published: March 2020

Information Technology (IT) governance has been emerging as a central issue in many organizations. This is because IT governance is key to realizing IT business value. Past studies have focused on the three aspects of IT governance, namely, structural capability, process capability and relational capability. At the same time, some studies have suggested that IT governance process should be viewed as a learning process rather than a problem solving process. Based on this scenario, the role of knowledge and knowledge based processes should be the central focus of IT governance. As a learning process, IT governance effectiveness can be determined by how much impact IT governance practices has influenced on decision-makers’ thinking and actions. In this case, knowledge capacity absorbed from IT governance experience reflects a certain level of organizational learning (OL) achieved which later influences the level of IT governance performance. Since studies that adopt this perspective is lacking, this paper proposes a conceptual framework based on absorptive capacity approach for an IT governance performance model in the higher education. The paper contributes theoretically by extending the knowledge of IT governance by exploring a new perspective on OL.

In this study, we developed a document for managing Information Technology suppliers in hospitals. This document is used to ensure the proper management of IT suppliers in the hospital. Products and services in Information Technology have characteristics and specifications that are always up to date, making it difficult for non-IT people to understand. Hospitals whose main business in the health sector is often lack of human resources who understand IT. Observations and interviews were conducted in Indonesian hospital, to identify the characteristics and problems in supplier management. Control Objectives for Information and Related Technologies (COBIT), Information Technology Infrastructure Library (ITIL) and government regulations on supplier management were reviewed and combined as a benchmark and guidance on how supplier management activities are carried out. The result of the process is a Standard Operating Procedure (SOP) document. The parties involved in the supplier management process have evaluated the SOP document. From the results of the study, it is known that currently, the hospital is still focused on procedures procurement of goods and services that are government regulated. This study proposes some new activities that are not currently done by the hospital.

The utilization of satellites for communication systems has expanded considerably in recent years. C and Ku-bands of frequencies are already congested because of high demand. Future directions of satellite communications are moving towards Ka and V-bands. Earth to satellite communications are moving towards higher frequency bands in future which are more sensitive to environment. Rain causes severe degradation in performances at higher frequency bands specially in tropical regions. Several mitigation techniques are proposed to design reliable system. Time diversity is one of the potential candidate for it. However, time diversity analysis requires measured rain attenuation data. For future high frequency link design those data are not available at most of the places. This thesis proposes a method to utilize 1-minute rain rate to analyze time diversity technique at any desired frequency. This paper proposes a method to utilize 1-minute rain rate to analyse time diversity rain rate gain. In proposed method, it is assumed that rain rate gain with delay can represent rain attenuation gain with delay for same period of time at same location. The characteristics of rain rate and rain attenuation almost same because the attenuation causes due to rain. One year measured rain rate in Malaysia is used to predict rain rate gain. The measured gain at 12.225 GHz signal is compared with that predicted by ITU-R based on rain rate measurement and is found good agreement. Hence it is recommended that the time diversity gain can be predicted using measured rain rate for any desired frequencies.

Oil palm loose fruit have always been part of oil palm harvesting operation. The current manual loose fruit collection by hand picking or raking is contributing to the minimum productivity and large amounts of debris. Effort in future shall be explored for the potential machine or system to collect the loose fruit in the field with the result of clean loose fruit. A new machine for loose fruit collection is being developed and examined which knows as Integrated Oil Palm Loose Fruit Collection Machine for collecting loose fruit from the palm base. Consist of three main integrated stages; the suction stage is used to collect the loose fruit, followed by segregating stage, which used to segregate the loose fruit from debris through double layer rotating drum and unloading stage of loose fruit to the 3-4 metric tons bin by using hydraulic tipping cylinder. Result indicates that at least more than 50% productivity of loose fruit collection were increased. In addition, the clean loose fruit collection resulted with the debris less than 10%. Hence, with this development, better quality loose fruits are collected with minimum debris for further processing in the palm oil mill, which will contribute to better oil extraction rate.

Published: March 2020

This paper presents a comparative analysis of chattering in sliding mode controlled DC-DC buck converter for chattering suppression using constant plus proportional reaching law and proposed reaching laws. A smooth SMC is used for chattering suppression in buck converter. The different switching functions are used in proposed reaching laws and constant plus proportional reaching law applied to SMC buck converter, the tan hyperbolic reaching law, sigmoid reaching law and constant plus proportional rate reaching law. The proposed method tan hyperbolic gives less switching loss among the reaching laws and stable output voltage. Inturn, performance of the buck converter increases, tanhyperbolic reaching law is more sensitive to matched, mismatched disturbance and parameter uncertainties. Loading conditions are also applied to the buck converter to measure the disturbances and parametric variations. The results are verified by MATLAB/Simulink.

Morphology and vocalization support specific status of the Chestnut-headed Chachalaca, Ortalis motmot ruficeps (Wagler, 1830) (Aves; Galliformes; Cracidae)
Authors: Tomotani Barbara Mizumo , Silveira Luís Fábio , Pacheco José Fernando 
Published: March 2020

The Little Chachalaca (Ortalis motmot) is a widely distributed species in the Amazon basin, typically found in riverine habitats. There are two disjunct populations: the northern O. m. motmot and the southern O. m. ruficeps (known as Chestnut-headed Chachalaca). Here we performed a vocal, morphological and plumage comparison between these two taxa. Birds present differences in tail coloration but are otherwise undiagnosable in terms of plumage. Ortalis m. ruficeps is, however, markedly smaller and lighter than O. m. motmot, with no overlap in size or weight. We also found vocal differences between O. m. motmot and O. m. ruficeps, no overlap in geographic distributions and no signs of hybridization across its range. Based on the available data, Ortalis m. ruficeps thus must be considered a valid species, endemic to Brazil.

Background
Left ventricular (LV) systolic dysfunction is reversible in some patients once the arrhythmia is controlled. However, identifying this arrhythmia‐induced cardiomyopathy among patients with LV systolic dysfunction is challenging. We explored the factors predicting the reversibility of the LV ejection fraction (LVEF) after catheter ablation of atrial fibrillation and/or atrial flutter in patients with LV systolic dysfunction.

Methods and Results

Forty patients with a reduced LVEF (LVEF <50%; 66.2±10.7 years; 32 men) who underwent atrial fibrillation/atrial flutter ablation were included. Transthoracic echocardiography was performed before and during the early (<4 days) and late phases (>3 months) after the ablation. Responders were defined as having a normalized LVEF (≥50%) during the late phase after the ablation. The LVEF improved from 39.8±8.8 to 50.9±10.9% at 1.2±0.6 days after the procedure, and to 56.2±12.2% at 9.6±8.0 months after the procedure (both for
P
<0.001). Thirty (75.0%) patients were responders. The preprocedural echocardiographic parameters were comparable between the responders and nonresponders. In the multivariate analysis, the preprocedural high‐sensitivity troponin T was the only independent predictor of the recovery of the LV dysfunction during the late phase after ablation (odds ratio, 1.17; 95% CI, 1.06–1.33;
P
=0.001), and a level of ≤12 pg/mL predicted recovery of the LV dysfunction with a high accuracy (sensitivity, 90.0%; specificity, 76.7%; positive predictive value, 56.3%; and negative predictive value, 95.8%).

Conclusions
Preprocedural high‐sensitivity troponin T levels might be a simple and useful parameter for predicting the reversibility of the LV systolic dysfunction after atrial fibrillation/atrial flutter ablation in patients with a reduced LVEF.
Extracorporeal Cardiopulmonary Resuscitation for Out‐of‐Hospital Cardiac Arrest in Adult Patients
Authors: Inoue Akihiko , Hifumi Toru , Sakamoto Tetsuya , Kuroda Yasuhiro 
Published: March 2020

Abstract
Extracorporeal cardiopulmonary resuscitation (ECPR) followed by targeted temperature management has been demonstrated to significantly improve the outcomes of out‐of‐hospital cardiac arrest (OHCA) in adult patients. Although recent narrative and systematic reviews on extracorporeal life support in the emergency department are available in the literature, they are focused on the efficacy of ECPR, and no comprehensively summarized review on ECPR for OHCA in adult patients is available. In this review, we aimed to clarify the prevalence, pathophysiology, predictors, management, and details of the complications of ECPR for OHCA, all of which have not been reviewed in previous literature, with the aim of facilitating understanding among acute care physicians. The leading countries in the field of ECPR are those in East Asia followed by those in Europe and the United States. ECPR may reduce the risks of reperfusion injury and deterioration to secondary brain injury. Unlike conventional cardiopulmonary resuscitation, however, no clear prognostic markers have been identified for ECPR for OHCA. Bleeding was identified as the most common complication of ECPR in patients with OHCA. Future studies should combine ECPR with intra‐aortic balloon pump, extracorporeal membrane oxygenation flow, target blood pressure, and seizure management in ECPR.

Published: March 2020

Abstract
The present study formulates a scale consisting of items that have valid and reliable psychometric properties to measure Muslim religiosity, and to see whether any variations exist by gender and age. In a sample of people aged 10 and older with at least primary education, the study found that four factors (Religious Involvement, Religious Commitment, Religious Beliefs, and General Optimism) can measure Muslim religiosity with a high level of validity and reliability. Muslim females are more religious than males and religiosity increases steadily with age.

Published: March 2020

Species of the genus Lythrum Linnaeus (1753: 446) (Lythraceae) occur in temporary pools and wetlands (Morris, 2007) with about 35 species around the world (Graham, 2007). In the Mediterranean area, there are more than 10 species that mostly occur in temporary pools (Castroviejo Bolibar et al., 1997; Tison et al. 2014). Most of the species are also present in East and Central Asia (Webb, 1968). However, some species are limited to Europe, mostly Western Europe, e.g. L. flexuosum Lagasca (1816: 16) and L. baeticum González-Albo (1936: 141) (Castroviejo Bolibar et al., 1997), some are limited to West Asia, e.g. L. silenoides Boissier & Noë (in Boissier 1856: 55) (Ghazanfar, 2016), while Lythrum salicaria Linnaeus (1753: 446), the loosestrife, is widely distributed in Asia, Europe, Africa, Oceania and introduced in North America.
Stokesosauridae clade nov., a new family name for a branch of basal tyrannosauroids

Published: March 2020

The majority of tyrannosauroid phylogenies published in the last 10 years have recovered a clade of basal tyrannosauroids that include Stokesosaurus clevelandi Madsen, 1974, Eotyrannus lengi Hutt et al., 2001 and Juratyrant langhami (Benson, 2008), which is positioned between Dilong Xu et al., 2004 and more derived tyrannosauroids such as Xiongguanlong Li et al., 2010 (e.g., Brusatte et al., 2010, 2011; Brusatte and Benson, 2013; Lü et al., 2014; Brusatte and Carr, 2016; Yun, 2016; Carr et al., 2017; Delcourt and Grillo, 2018; Nesbitt et al., 2019; Zanno et al., 2019; Wu et al., 2020). Carr et al. (2017) first called this clade as “Stokesosauridae”, but did not define or diagnose this clade; but later the name was adopted and used as valid by Wu et al. (2020).
