Introduction Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by thromboembolic events, including ischemic stroke or complications in pregnancy, and the presence of antiphospholipid antibodies. Cervical artery dissection (CAD) is not an uncommon cause of stroke in young adults. The concomitant presence of APS and CAD is extremely rare. Methods Two cases with APS who developed acute ischemic strokes related to CAD are reported. A comprehensive systematic literature search using the PubMed database was also conducted. Results In Case 1, a 36-year-old woman who had been diagnosed with systemic lupus erythematosus and had been repeatedly positive for lupus anticoagulant tests developed an ischemic stroke caused by a vertebral artery dissection (VAD). After admission, she had a recurrent ischemic stroke, followed by considerable changes in steno-occlusive lesions of the vertebrobasilar artery system. In Case 2, a 36-year-old man developed multiple brain infarcts due to bilateral VAD with aneurysmal formations and associated with pulmonary embolism. The anticardiolipin antibody titer was repeatedly elevated after stroke. The literature review identified 8 patients with CAD associated with APS, involving the internal carotid artery in 6 patients and the middle cerebral artery and vertebral artery in 1 patient each. The patients were predominantly young and female, infrequently had atherosclerotic vascular risk factors, and were positive for various antiphospholipid antibodies. Conclusions The current report described two rare cases of ischemic stroke caused by CAD secondary to APS, along with a review of the literature; the patients displayed characteristic clinical manifestations, implying specific mechanisms for cerebral artery disorders secondary to APS.

Published: October 2020

Purpose: Coauthorship is a means for assessing each contributor’s effort on a joint publication. This study aims to identify methods to determine publication coauthorship for crediting effort and order. Method: The research team searched for a framework to affirm the decision-making process when preparing for a coauthored publication by analyzing existing literature and published guidelines in authorship determination. Results: Four coauthorship principles—fairness, accountability, transparency, and effort (FATE)—were described with guidelines. The FATE framework helped the team develop a checklist for scholars to document their research productivity in collaborative projects. Examples of questions were derived from the framework to stimulate educational discussions and collaborative research ideas. Discussion: The coauthorship checklist could provide support for mentors to evaluate their protégés’ performance. Further research is needed to justify its application for initiating conversations about coauthorship. Operational guidelines should also be developed to prevent biases in reporting effort contributions.

Published: October 2020

Objects: Our previous research work reported the beneficial effects of angiotensin receptor blockers (ARBs) for the treatment of diabetes associated cataract which was induced by streptozotocin (STZ). The current study, evaluated the effects of topical administration of various renin angiotensin modulators on STZ-induced cataracts in rats. Methods: Single dose of STZ (60 mg/kg, i.p.) was administered in the rats to induce diabetes. Animals were divided into normal and diabetic rats. Normal rats were administered with single dose of sodium citrate buffer (0.1 M, 10ml/kg, i.p.). Diabetic animals were divided into various treatment groups, each group contains six animals and received aliskiren, olmesartan, enalapril, and angiotensin 1–7 at a dose of 0.5% w/v topically on the cornea of the eye for a period of 8 weeks. During experimental protocol morphology of the eyes and lenticular opacity were monitored. Animals were sacrificed after 8 weeks of drug treatment, and various cataractogenic biochemical parameters were assessed. Results: Topical administrations with aliskiren, enalapril, olmesartan, and angiotensin 1–7 showed non-significant alterations in the blood glucose level, but significantly decreased lenticular opacity, restored antioxidant level, restored MDA level and Nitrite content, and decreased the onset of cataract formation. Conclusion: Overall, our findings suggest that topical treatment with renin angiotensin modulators delayed the onset of diabetes-induced cataract formation.

Background: Multiple sclerosis may damage cognitive performance in several domains, including attention. Although attention network deficits were described during rest, studies that investigate their function during task performance are scarce. Objective: To investigate connectivity within and between task-related networks in multiple sclerosis during a visual attention task as a function of cognitive performance. Methods: A total of 23 relapsing-remitting multiple sclerosis (RRMS) patients and 29 healthy controls underwent task-functional magnetic resonance imaging (fMRI) scans using a visual attention paradigm on a 3T scanner. Scans were analysed using tensor-independent component analysis (TICA). Functional connectivity was calculated within and between components. We assessed cognitive function with the Brief International Cognitive Assessment for MS (BICAMS) battery. Results: TICA extracted components related to visual processing, attention, executive function and the default-mode network. Subject scores of visual/attention-related and executive components were greater in healthy controls ( p < 0.032, p < 0.023). Connectivity between visual/attention-related and default-mode components was higher in patients ( p < 0.043), correlating with Brief Visuospatial Memory Test–Revised (BVMT-R) scores ( R = −0.48, p < 0.036). Patients showed reduced connectivity between the right intraparietal sulcus (rIPS) and frontal eye field (rFEF), and bilateral frontal eye fields ( p < 0.012, p < 0.003). Reduced rIPS-rFEF connectivity came with lower Symbol Digit Modalities Test (SDMT)/BVMT-R scores in patients ( R = 0.53, p < 0.02, R = 0.46, p < 0.049). Conclusion: Attention-related networks show altered connectivity during task performance in RRMS patients, scaling with cognitive disability.

Published: October 2020

Background The impact of hand dominance on the expected (motor and functional ability and daily use) improvement of the affected upper extremity (UE) in subacute stroke has not yet been investigated. Objectives To compare between the affected dominant and affected nondominant UE (1) on rehabilitation admission (T1) for motor and sensory abilities, functional ability, and daily use and (2) 6 weeks poststroke onset (T2) and the UE recovery between T1 and T2 regarding percent change, improvement effect size, and percent of participants achieving minimal clinical important difference (MCID). Methods Multicenter longitudinal study. Results Thirty-eight participants with affected dominant and 51 participants with affected nondominant UE were recruited. On T1 and T2, between-group differences were not seen for all UE variables. Significant improvement in the motor and functional ability, daily use, and perceived recovery between T1 and T2 were seen for the affected dominant ( z = −3.01 to −4.13, P < .01) and nondominant UEs ( z = −4.59 to −5.32, P < .01). Effect size improvement values were moderate and large in the affected dominant and nondominant UE (respectively). In addition, 14% to 40% of the participants in both UEs achieved MCID. Conclusions Significant and similar clinical meaningfulness in UE improvement can be expected during subacute rehabilitation; however, improvement magnitude and percent improvement is different for the UE domains of the affected dominant and the affected nondominant UEs. These findings highlight the distinct roles of the dominant and nondominant hands during bimanual daily activities, which can guide clinicians during stroke rehabilitation.

Published: October 2020

Background: Patient involvement in decision-making plays a prominent role in improving the quality of healthcare. Despite this, shared decision-making is not routinely implemented. However, electronic assessment tools that capture patients’ history, symptoms, opinions and values prior to their medical appointment are used by healthcare professionals during patient consultations to facilitate shared decision-making. Objective: To assess the effectiveness of electronic assessment tools to improve the shared decision-making process. Method: A systematic review was conducted following PRISMA guidelines. Published literature was searched on MEDLINE, EMBASE and PsycINFO to identify potentially relevant studies. Data were extracted and analysed narratively. Results: Seventeen articles, representing 4004 participants, were included in this review. The main findings were significant improvement in patient–provider communication and provider management of patient condition in the intervention group compared to the control group. In contrast, patient–provider satisfaction and time efficiency were assessed by relatively few included studies, and the effects of these outcomes were inconclusive. Conclusion: This review found that communication and healthcare professional’s management of a patient’s condition improves because of the use of electronic questionnaires. This is encouraging because the process of shared decision-making is reliant on high-quality communication between healthcare professionals and patients. Implications: We found that this intervention is especially important for people with chronic diseases, as they need to establish a long-term relationship with their healthcare provider and agree to a treatment plan that aligns with their values. More rigorous research with validated instruments is required.

Authors: Hailu Gebru Tsegu , Hagos Mekonen Haftea , Gemechu Kiros Kbrom 
Published: October 2020

Background: Good knowledge of self-care related to heart failure (HF) is key to improve patient outcomes. However, information regarding how much patients know about self-care is lacking in developing countries, particularly in the study setting. Objective: The objectives of this study were to assess HF patients’ knowledge about self-care and to explore predictors among HF patients in Ayder comprehensive specialised referral hospital, Tigray, Ethiopia. Methods: This hospital-based cross-sectional study design was undertaken in Ayder comprehensive specialised referral hospital, Tigray, Ethiopia. A total of 408 HF patients participated, and the study was done between February and April 2018. An interviewer-assisted structured questionnaire was used to collect data. Bivariate logistic regression and multivariable logistic regression were conducted to identify the predictors associated with knowledge about self-care. Results: The mean age of the participants was 45.4 years (standard deviation=19 years). Around 255 (62.5%) of the participants had poor self-care knowledge. Age, New York Heart Association classes, duration of the disease and previous hospitalisation were the factors associated with knowledge about self-care. Conclusion: More than half of all participants had poor knowledge about self-care. Improving existing prevention strategies and strengthening patients’ knowledge are recommended to address this knowledge deficit.

Published: October 2020

Objective: Clinical decision support systems (CDDSs) in the electronic medical record (EMR) have been implemented in primary care settings to identify patients due for cancer screening tests, while functioning as a real time reminder system. There is little known about primary care providers (PCPs) perspective or user acceptance of CDSS. The purpose of this study was to investigate primary care provider perceptions of utilizing CDSS alerts in the EMR to promote increased screening rates for breast cancer, cervical cancer, and colorectal cancer. Methods: An electronic survey was administered to PCPs in a Midwest Health Institution community internal medicine practice from September 25, 2019 through November 27, 2019. Results: Among 37 participants (9 NP/Pas and 28 MD/DOs), the NP/PA group was more likely to agree that alerts were helpful (50%; P-value = .0335) and the number of alerts (89%; P = .0227) in the EMR was appropriate. The NP/PA group also was more likely to find alerts straightforward to use (78%, P = .0239). Both groups agreed about feeling comfortable using the health maintenance alerts ( MD/DO = 79%; NP/PA = 100%). Conclusion: CDSSs can promote and facilitate ordering of cancer screening tests. The use of technology can promptly identify patients due for a test and act as a reminder to the PCP. PCPs identify these alerts to be a beneficial tool in the EMR when they do not interrupt workflow and provide value to patient care. More work is needed to identify factors that could optimize alerts to be even more helpful, particularly to MD/DO groups.

Published: October 2020

Purpose: To compare dilated smartphone-based imaging with a nonmydriatic, tabletop fundus camera as a teleophthalmology screening tool for diabetic retinopathy (DR). Methods: This was a single-institutional, cross-sectional, comparative-instrument study. Fifty-six patients at a safety-net hospital underwent teleophthalmology screening for DR using standard, nonmydriatic fundus photography with a tabletop camera (Nidek NM-1000) and dilated fundus photography using a smartphone camera with lens adapter (Paxos Scope, Verana Health). Masked graders performed standardized photo grading. Quantitative comparisons were performed employing descriptive, κ, Bland-Altman, and receiver operating characteristic analyses Results: Posterior segment photography was of sufficient quality to grade in 89% of mydriatic smartphone-imaged eyes and in 86% of nonmydriatic tabletop camera-imaged eyes ( P = .03). Using the tabletop camera as the reference to detect moderate nonproliferative DR or worse (referral-warranted DR), mydriatic smartphone-acquired photographs were found to be 82% sensitive and 96% specific. Dilated smartphone imaging detected referral-warranted DR in 3 eyes whose tabletop camera imaging did not demonstrate referral-warranted DR. Secondary masked review of medical records for the discordances in referral-warranted status from the two imaging modalities was performed, and it revealed revised sensitivity and specificity values of 95% and 98%, respectively. Overall, there was good agreement between tabletop camera and smartphone-acquired photo grades (κ = 0.91 ± 0.1, P < .001; area under the receiver operating characteristic curve = 0.99, 95% CI, 0.98-1.00). Conclusions: Mydriatic smartphone-based imaging resulted in fewer ungradable photos compared to nonmydriatic table-top camera imaging and detected more patients with referral-warranted DR. Our study supports the use of mydriatic smartphone teleophthalmology as an alternative method to screen for DR.

Published: October 2020

BackgroundAsthma exacerbations are commonly associated with rhinovirus (RV) infection. Interleukin-33 (IL-33) plays an important role during exacerbation by enhancing Type 2 inflammation. Recently we showed that RV infects bronchial smooth muscle cells (BSMCs) triggering production of interferons and IL-33. Here we compared levels of RV-induced IL-33 in BSMCs from healthy and asthmatic subjects, and explored the involvement of pattern-recognition receptors (PRRs) and downstream signalling pathways in IL-33 expression.MethodBSMCs from healthy and severe and non-severe asthmatic patients were infected with RV1B or stimulated with the PRR agonists poly(I:C) (Toll-like receptor 3 (TLR3)), imiquimod (TLR7) and poly(I:C)/LyoVec (retinoic acid-inducible gene 1 (RIG-I)/melanoma differentiation-associated protein 5 (MDA5)). Knockdown of TLR3, RIG-I and MDA5 was performed, and inhibitors targeting TBK1, nuclear factor-κB (NF-κB) and transforming growth factor (TGF)-β-activated kinase 1 (TAK1) were used. Gene and protein expression were assessed.ResultsRV triggered IL-33 gene and protein expression in BSMCs. BSMCs from patients with non-severe asthma showed higher baseline and RV-induced IL-33 gene expression compared to cells from patients with severe asthma and healthy controls. Furthermore, RV-induced IL-33 expression in BSMCs from healthy and asthmatic individuals was attenuated by knockdown of TLR3. Inhibition of TAK1, but not NF-κB or TBK1, limited RV-induced IL-33. The cytokine secretion profile showed higher production of IL-33 in BSMCs from patients with non-severe asthma compared to healthy controls upon RV infection. In addition, BSMCs from patients with non-severe asthma had higher levels of RV-induced IL-8, TNF-α, IL-1β, IL-17A, IL-5 and IL-13.ConclusionRV infection caused higher levels of IL-33 and increased pro-inflammatory and Type 2 cytokine release in BSMCs from patients with non-severe asthma. RV-induced IL-33 expression was mainly regulated by TLR3 and downstreamviaTAK1. These signalling molecules represent potential therapeutic targets for treating asthma exacerbations.

Published: October 2020

BackgroundDespite well-documented case series of hypersensitivity pneumonitis (HP), epidemiological data delineating relative contributions of risk factors are sparse. To address this, we estimated HP risk in a case-referent study of occupational and nonoccupational exposures.MethodsWe recruited cases of HP by ICD-9 codes from an integrated healthcare delivery system (IHCDS) and a tertiary medical care centre. We drew referents, matched for age and sex, from the IHCDS. Participants underwent comprehensive, structured telephone interviews eliciting details of occupational and home environmental exposures. We employed a hierarchical analytic approach for data reduction based on the false discovery rate method within clusters of exposures. We measured lung function and selected biomarkers in a subset of participants. We used multivariate logistic regression to estimate exposure-associated odds ratios (ORs) and population attributable fractions (PAFs) for HP.ResultsWe analysed data for 192 HP cases (148 IHCDS; 44 tertiary care) and 229 referents. Occupational exposures combined more than doubled the odds of developing HP (OR 2.67; 95% CI 1.73–4.14) with a PAF of 34% (95% CI 21–46%); nonoccupational bird exposure also doubled the HP odds (OR 2.02; 95% CI 1.13–3.60), with a PAF of 12% (3–21%). Lung function and selected biomarkers did not substantively modify the risk estimates on the basis of questionnaire data alone.DiscussionIn a case-referent approach evaluating HP risk, identifiable exposures accounted, on an epidemiological basis, for approximately two in three cases of disease; conversely, for one in three, the risk factors for disease remained elusive.

PURPOSE The coronavirus disease 2019 (COVID-19) pandemic has had a global impact, and Singapore has seen 33,000 confirmed cases. Patients with cancer, their caregivers, and health care workers (HCWs) need to balance the challenges associated with COVID-19 while ensuring that cancer care is not compromised. This study aimed to evaluate the psychological effect of COVID-19 on these groups and the prevalence of burnout among HCWs. METHODS A cross-sectional survey of patients, caregivers, and HCWs at the National Cancer Centre Singapore was performed over 17 days during the lockdown. The Generalized Anxiety Disorder-7 and Maslach Burnout Inventory were used to assess for anxiety and burnout, respectively. Self-reported fears related to COVID-19 were collected. RESULTS A total of 624 patients, 408 caregivers, and 421 HCWs participated in the study, with a response rate of 84%, 88%, and 92% respectively. Sixty-six percent of patients, 72.8% of caregivers, and 41.6% of HCWs reported a high level of fear from COVID-19. The top concern of patients was the wide community spread of COVID-19. Caregivers were primarily worried about patients dying alone. HCWs were most worried about the relatively mild symptoms of COVID-19. The prevalence of anxiety was 19.1%, 22.5%, and 14.0% for patients, caregivers, and HCWs, respectively. Patients who were nongraduates and married, and caregivers who were married were more anxious. The prevalence of burnout in HCWs was 43.5%, with more anxious and fearful HCWs reporting higher burnout rates. CONCLUSION Fears and anxiety related to COVID-19 are high. Burnout among HCWs is similar to rates reported prepandemic. An individualized approach to target the specific fears of each group will be crucial to maintain the well-being of these vulnerable groups and prevent burnout of HCWs.
