Abstract
IntroductionOpioid dependent individuals frequently complain of sleep problems in withdrawal and during abstinence.ObjectivesThe objectives were to assess the subjective sleep parameters among buprenorphine-maintained opioid-dependent patients and to correlate it with socio-demographics, concomitant drug use and treatment related variablesMethodsUsing a cross-sectional study design, 106 hundred six opioid-dependent patients maintained on buprenorphine for at least six months and on same dose in past month were interviewed. Sleep was assessed by Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale. Association between subjective sleep parameters, socio-demographics, concomitant drug use and treatment related variables was also studied.ResultsAll participants were males. Their mean age was 41.1 years (SD:14.3). The mean duration of illicit opioid use was 10 years (IQR: 5,22). About 63.2% (n=67) had PSQI scores more than 5 denoting sleep problem. The scores obtained in Epworth Sleeping Scale were in normal range. Mean subjective total sleep time of the sample was 403.5 (SD 94.8) minutes and median sleep latency was 35 (IQR 18.8, 62.5) minutes. Subjective total sleep time was significantly higher in participants who had use tobacco in the past three months (p value=0.03) and who were in moderate ASSIST risk category (p value=0.04). Subjective sleep latency was significantly higher (p value=0.04) in participants who had used opioids in last three months. It was observed that age was a significant predictor of subjective total sleep time and OST compliance was a significant predictor of sleep latency.ConclusionsA sizeable proportion of opioid dependent patients on buprenorphine have sleep problems

Abstract
Abstract
Background
Invasive medical procedures such as colonoscopies are known to cause psychological distress and anxiety. Patient anxiety leads to reduce patient compliance for colonoscopy and increased adverse effects. Patient education prior to colonoscopy has previously been shown to have positive effects on outcomes and experience. Based on patient and provider input, we have developed easy to read written materials and easy to follow video materials, which other patients have rated highly. These, along with other materials, are embedded on Mycolonoscopy.ca. Mycolonoscopy.ca is a website that provides online information access for patients regarding preparation and peri-procedural expectations. Information about accessing the website is provided with appointment materials (which includes information about split-dose versus one day bowel preparation, giving patients the option between the two) mailed to all patients undergoing outpatient colonoscopy in Winnipeg.
Aims
(1) To evaluate the current use of mycolonoscopy.ca among patients undergoing colonoscopy (2) To determine whether there is an association between visitation to the website and patient outcomes such as reduction in procedural anxiety, bowel preparation tolerance/compliance, and bowel preparation score.
Methods
A paper-based survey was given out to patients at their colonoscopy appointments. Univariate and multivariate logistic regression analyses was performed to determine the factors associated with website visitation and association with procedural anxiety, bowel preparation compliance and bowel preparation scores.
Results
A total of 593 participants were given the surveys, of which 506 were completed. 17.4% of participants had visited the website prior to their colonoscopy. Visitors to mycolonoscopy.ca and those that had heard of the website were more likely to consume a split-dose bowel preparation (63.9% and 68.2% respectively) compared with non-visitors (52.5%) (p=0.0062). Individuals who consumed split-dose bowel preparation had a median Boston bowel preparation score of 9, compared with a score of 7 for individuals who used other forms of preparation (p<0.0001). 31.3% of website visitors were very or extremely worried about their colonoscopy compared with 17.9% of non-visitors. 76.6% of individuals agreed or strongly agreed that visiting the website helped them prepare for their colonoscopy and 69.7% who visited the website agreed or strongly agreed that it helped to reduce their stress/anxiety for the procedure as well.
Conclusions
Our study suggests that use of an informative online platform such as mycolonoscopy.ca can help to improve patient education prior to colonoscopy, reduce anxiety and stress surrounding the procedure, and improve bowel preparation compliance and bowel cleansing score.

Abstract
Background Little is known about the impact of hormone therapy on transgender youth with Cystic Fibrosis (CF). This case report describes an 18-year-old affirmed female with CF who was treated with hormone therapy associated in timing with new growth of Pseudomonas aeruginosa in her sputum culture. Discussion We highlight important considerations, including the impact of gender-affirming hormone therapy on overall CF disease course. Evidence supports that females with CF have worse outcomes than males, which are partly attributed to estrogen effects. Pseudomonas aeruginosa is one of the most prevalent pathogens in people with CF. Here, we highlight a transfemale who grows Pseudomonas aeruginosa for the first time since her youth, nearly 1 year after starting estrogen therapy. This is consistent with previous literature of an association between high estrogen levels and Pseudomonas aeruginosa prevalence, but has never been evaluated in a transgender population. Conclusion Through this case, we demonstrate the need for additional research to understand the relationship between gender-affirmative hormone transition and CF care and management.

Abstract
BACKGROUND AND PURPOSE Various patterns of leukoencephalopathy have been described in coronavirus disease 2019 (COVID-19). In this article, we aimed to describe the clinical and imaging features of acute disseminated leukoencephalopathy in critically ill patients with COVID-19 and the imaging evolution during a short-term follow-up. MATERIALS AND METHODS We identified and reviewed the clinical data, laboratory results, imaging findings, and outcomes for 8 critically ill patients with COVID-19 with acute disseminated leukoencephalopathy. RESULTS All patients demonstrated multiple areas of white matter changes in both cerebral hemispheres; 87.5% (7/8) of patients had a posterior predilection. Four patients (50%) had short-term follow-up imaging within a median of 17 days after the first MR imaging; they developed brain atrophy, and their white matter lesions evolved into necrotizing cystic cavitations. All (8/8) patients had inflammatory cytokine release syndrome as demonstrated by elevated interleukin-6, D-dimer, lactate dehydrogenase, erythrocyte sedimentation rate, C-reactive protein, and ferritin levels. Most (7/8; 87.5%) patients were on prolonged ventilator support (median, 44.5 days; interquartile range, 20.5 days). These patients had poor functional outcomes (6/8 [75%] patients were discharged with mRS 5) and high mortality (2/8, 25%). CONCLUSIONS Critically ill patients with COVID-19 can develop acute disseminated leukoencephalopathy that evolves into cystic degeneration of white matter lesions with brain atrophy during a short period, which we dubbed virus-associated necrotizing disseminated acute leukoencephalopathy. This may be the result of COVID-19-related endothelial injury, cytokine storm, or thrombotic microangiopathy.

Abstract
The current investigation reports a novel and facile method for modification of low molecular weight chitosan (Cs) with guanidine moieties, aimed at enhancing its cellular interaction and thus augmenting its cellular internalization. Guadinylated chitosan-copper (Cs-Gn-Cu) chelates, based on copper-nitrogen co-ordination, were established. Characterization of chelates was conducted using 1H NMR, 13C NMR, XPS, XRD, TGA-DTA, and GPC techniques. Anticancer activity of formed chelates was confirmed against A549 cells using MTT assay. Experimental outcomes, for the first time, have provided an empirical evidence for synergistic interaction between the chelated polymer (Cs-Gn-Cu) and the established anti-cancer agent, Doxorubicin (Dox), based on analysis by the Chou Talalay method and estimation of their combination indices. ROS induction was demonstrated as the mechanism of action of the chelated polymer, which supplemented rapid destruction of cancerous cells by Dox. These findings strongly advocate the need for harnessing unexplored potential of these innovative metal polymer chelates in cases of Dox resistant lung cancer, wherein the polymeric system itself would serve as an anti-cancer agent.

Abstract
BACKGROUND Hypothermia at admission to neonatal intensive care units (NICU) is associated with increased morbidity and mortality in newborns. A baseline study at a tertiary care hospital with all out-born babies showed admission hypothermia of 82%. OBJECTIVE To reduce admission hypothermia (moderate) in newborns at least by 50% in next 6 months. METHODS A quality improvement (QI) study was planned using WHO Point of Care Quality Improvement Model (POCQI), [17] using PDSA (Plan-Do-Study-Act) cycle approach from April 2018 to March 2019, and including 427 term and preterm babies. We educated the staff, reinforced the use of caps, cling wraps, warm linen, introduced Ziploc bags and ensured adequate use of transport incubator. RESULTS After 6 months, overall admission hypothermia decreased from 82% to 45%, moderate hypothermia reduced from 46% to <10% (P < 0.001) and severe hypothermia (3%) was completely eliminated. There was also significant reduction in incidence of Intraventricular hemorrhage (13% Vs 4.7%), Late onset neonatal sepsis (38% Vs 19%) and metabolic acidosis (43% Vs 28%). We were able to sustain this improvement for the next 6 months and is ongoing. The strongest predictor of hypothermia was newborns being in the phase before QI initiative was started (OR 2.36, 95% CI 1.47, 3.23). CONCLUSION This study is a cost effective approach in reducing admission hypothermia in NICU in a resource limited setting with all outborn babies, and further decreasing the morbidity associated with it. Hence, emphasizing the importance of maintaining euthermia, not only in delivery rooms, but also during transportation.

Abstract
UNLABELLED We examined fragility fracture patients' perceptions of associations between bone health and other chronic conditions and medications. Awareness of the associations between bone health and these conditions and medications was low. Providers should increase patients' awareness of these associations in order to minimize the risk of future fracture. INTRODUCTION Among patients with a fragility fracture presenting with at least one other chronic health condition, we examined (1) perceptions of the association between bone health and their other health conditions, and (2) perceptions of the association between bone health and prescribed medications taken for other health conditions. METHODS We identified fragility fracture patients presenting to a Canadian urban fracture clinic with at least one self-reported chronic health condition (in addition to bone fragility). In-depth interviews, 60-90 min in duration, were conducted. Our qualitative methodology was informed by saliency analysis. RESULTS We interviewed 26 patients (21 females, 5 males) aged 45 to 84 years old. Participants were taking 1-13 medications each and presented with a variety of comorbidities (range 1-7). All participants described at least one condition or medication they were currently taking for which there existed evidence of a negative effect on bone health (increased risk of fracture, bone loss, falling). Two participants perceived a correct association between their other health conditions and compromised bone health, and four participants perceived a correct association between their medications and compromised bone health. CONCLUSION All patients reported a chronic health condition and/or were taking at least one medication that potentially compromised their bone health. Patient awareness of the association between bone health and other health conditions and prescribed medications was low. Health care providers should increase patients' awareness of the bone health significance of their chronic conditions and medications in order to minimize the risk of future fracture.

Abstract
Breast cancer accounts for 1.4 million new cases every year. Triple-negative breast cancer (TNBC) is one the leading cause of mortality in developing countries and is associated with early age onset (under 40 years old). Chemotherapy has a poor success rate in patients with TNBC as compared to other types of breast cancers. It is due to the lack of expression of three validated molecular markers for breast cancer, the estrogen and progesterone receptors, and the amplification of HER-2/Neu. Therefore, a clear need exists for a greater understanding of TNBC at all levels and for the development of better therapies. We have studied the anti-tumor effects of a potential drug, maslinic acid, which can be extracted from olive oil industry waste. This natural product showed inhibitory effect at concentrations ranging from 30 to 50 µM within 24 h. It exhibited divergent effects in cell cycle progression for the MCF7 (estrogen positive) cell line when compared with TNBCs like MDA-MB-231 and MDA-MB-468. Also, maslinic acid treatment altered the mitochondrial membrane electrochemical potential and the reactive oxygen species (ROS) levels to cause a caspase-independent programmed cell death. In silico approaches and immunoblotting suggested the involvement of the MAPK pathway explaining the variability in cell cycle progression along with the apoptotic cell death caused by maslinic acid.

Abstract
UNLABELLED We examined individuals' experiences using an educational booklet developed by the Ontario Osteoporosis Strategy. The booklet appeared to motivate individuals to make changes to their existing management of their bone health and served as a reference tool reaffirming current practices and beliefs for others. INTRODUCTION The purpose of this study was to examine individuals' experiences of the educational booklet and explore the influence of the booklet on individuals' beliefs and actions regarding their bone health. METHODS Eligible individuals were those who had been prescribed medication to treat low bone mass. One-on-one telephone interviews were conducted over an 18-month period. Participants were interviewed for approximately 1 hour and asked to provide their feedback on the booklet, and to discuss what they were doing with respect to the recommendations made in the booklet. RESULTS We interviewed 50 participants who ranged in age from 58 to 89. The overall impression of the booklet was positive. Participants described the language in the booklet as clear and easy to understand. Participants stated that they would have appreciated receiving this tool at the onset of their diagnosis. Forty-two participants had already taken action, or expressed an intention to make changes, to their existing routines to improve their bone health. In contrast, eight participants used the booklet to reaffirm current practices and beliefs. For these individuals, the recommendations made in the booklet were consistent with what they had already been doing. CONCLUSION The booklet can engage patients in discussions about bone health. The booklet appeared to motivate individuals to make changes to their existing routines in an effort to achieve better health outcomes for their bone health. Providing a tool like this to people recently diagnosed with a bone health issue may prove to be beneficial.

Abstract
Rigosertib is a styryl benzyl sulfone that inhibits growth of tumor cells and acts as a RAS mimetic by binding to Ras binding domains of RAS effectors. A recent study attributed rigosertib's mechanism of action to microtubule binding. In that study, rigosertib was obtained from a commercial vendor. We compared the purity of clinical-grade and commercially sourced rigosertib and found that commercially sourced rigosertib contains approximately 5% ON01500, a potent inhibitor of tubulin polymerization. Clinical-grade rigosertib, which is free of this impurity, does not exhibit tubulin-binding activity. Cell lines expressing mutant β-tubulin have also been reported to be resistant to rigosertib. However, our study showed that these cells failed to proliferate in the presence of rigosertib at concentrations that are lethal to wild-type cells. Rigosertib induced a senescence-like phenotype in the small percentage of surviving cells, which could be incorrectly scored as resistant using short-term cultures.

Abstract
Despite the severity of coronavirus disease 2019 (COVID-19) being more frequently related to acute respiratory distress syndrome and acute cardiac and renal injuries, thromboembolic events have been increasingly reported. We report a unique series of young patients with COVID-19 presenting with cerebral venous system thrombosis. Three patients younger than 41 years of age with confirmed Severe Acute Respiratory Syndrome coronavirus 2 (SARS-Cov-2) infection had neurologic findings related to cerebral venous thrombosis. They were admitted during the short period of 10 days between March and April 2020 and were managed in an academic institution in a large city. One patient had thrombosis in both the superficial and deep systems; another had involvement of the straight sinus, vein of Galen, and internal cerebral veins; and a third patient had thrombosis of the deep medullary veins. Two patients presented with hemorrhagic venous infarcts. The median time from COVID-19 symptoms to a thrombotic event was 7 days (range, 2-7 days). One patient was diagnosed with new-onset diabetic ketoacidosis, and another one used oral contraceptive pills. Two patients were managed with both hydroxychloroquine and azithromycin; one was treated with lopinavir-ritonavir. All patients had a fatal outcome. Severe and potentially fatal deep cerebral thrombosis may complicate the initial clinical presentation of COVID-19. We urge awareness of this atypical manifestation.

Abstract
During the height of the recent outbreak of coronavirus 19 (COVID-19) in New York City, almost all the hospital emergency departments were inundated with patients with COVID-19, who presented with typical fever, cough, and dyspnea. A small number of patients also presented with either unrelated conditions (such as trauma) or other emergencies, and some of which are now known to be associated with COVID-19 (such as stroke). We report such a scenario in 17 patients who were admitted and investigated with CT spine imaging and CT angiography for nonpulmonary reasons (trauma = 13, stroke = 4). Their initial work-up did not suggest COVID-19 as a diagnosis but showed unsuspected/incidental lung findings, which led to further investigations and a diagnosis of COVID-19.

Abstract
Background:Depression/anxiety are common in RA pts. SF-36 MCS ≤38 can identify probable major depressive disorder and/or probable generalised anxiety disorder (pMDD/pGAD) in RA pts. Tofacitinib is an oral JAK inhibitor for the treatment of RA.Objectives:To assess pMDD/pGAD prevalence in the tofacitinib RA program and efficacy by baseline (BL) pMDD/pGAD status.Methods:Data from pts receiving tofacitinib, ADA, or PBO were pooled from 5 Phase (P)3 and 1 P3b/4 trials. Demographics/BL characteristics were reported by BL pMDD/pGAD (SF-36 MCS ≤38, presence; >38, absence). Month (M)3/6/9/12 SF-36 MCS change from BL (Δ) was estimated, and % with pMDD/pGAD reported. M3/6/12 efficacy outcomes compared tofacitinib-treated pts by BL pMDD/pGAD.Results:BL pMDD/pGAD was seen in 44.5% (tofacitinib 5 mg BID), 39.8% (tofacitinib 10 mg BID), 45.4% (ADA 40 mg Q2W) and 39.1% (PBO) of pts. pMDD/pGAD pts had higher BL CRP and worse disability, fatigue, pain and sleep vs pts without. SF-36 MCS increases were greater for tofacitinib vs PBO/ADA (Fig 1a). The % of pts with BL pMDD/pGAD who continued to have pMDD/pGAD reduced over time, and was generally lower for tofacitinib vs PBO/ADA (Fig 1b). Regardless of BL pMDD/pGAD, efficacy was generally similar for tofacitinib 5 mg BID (Table) and 10 mg BID.Conclusion:~40% of RA pts had BL pMDD/pGAD. SF-36 MCS improvements were greater for tofacitinib vs PBO/ADA. With tofacitinib, % of pts with SF-36 MCS ≤38 reduced by ~60% at M12. Tofacitinib efficacy was similar in pts with/without BL pMDD/pGAD. Limitations include using SF-36 MCS to identify probable rather than confirmed MDD or GAD. Future research using gold standard psychiatric interviews to validate use of SF-36 MCS ≤38 is needed.Table.M3/6/12 efficacy with tofacitinib 5 mg BID, by BL pMDD/pGADaSF-36 MCS ≤38SF-36 MCS >38OR (95% CI)P valueACR20 (%)b,cM355.157.90.89 (0.74, 1.08)0.2330M661.762.80.96 (0.79, 1.16)0.6511M1258.458.60.99 (0.80, 1.22)0.9279ACR50 (%)b,cM325.929.20.85 (0.70, 1.03)0.1022M636.038.00.92 (0.76, 1.11)0.3724M1233.834.30.98 (0.80, 1.20)0.8366ACR70 (%)b,cM310.111.00.91 (0.69, 1.18)0.4704M616.516.51.00 (0.79, 1.26)0.9901M1218.317.51.06 (0.83, 1.34)0.6560DAS28-4(ESR)<2.6 (%)b,cM35.47.40.72 (0.49, 1.05)0.0872M65.98.50.68 (0.49, 0.94)0.0199*M128.011.90.64 (0.47, 0.89)0.0073**ΔHAQ-DI, LS meanc,dSF-36 MCS ≤38SF-36 MCS >38Difference (95% CI)P valueM3-0.41-0.430.01 (-0.04, 0.06)0.6008M6-0.49-0.48-0.01 (-0.06, 0.04)0.6617M12-0.52-0.52-0.01 (-0.06, 0.05)0.8475*p<0.05; **p<0.01 Data pooled from 5 P3 and 1 P3b/4 tofacitinib trialsaBL pMDD/pGAD = SF-36 MCS ≤38;bLogistic regression fit;cFor PBO pts advancing to tofacitinib post-M3, only PBO data were included;dMixed-effects linear model fitΔ, change from baseline; ACR, American College of Rheumatology; BID, twice daily; BL, baseline; CI, confidence interval; DAS28-4(ESR), Disease Activity Score in 28 joints, erythrocyte sedimentation rate; HAQ-DI, Health Assessment Questionnaire-Disability Index; LS, least squares; M, month; MCS, Mental Component Summary score; OR, odds ratio; P, Phase; pGAD, probable generalised anxiety disorder; PBO, placebo; pMDD, probable major depressive disorder; pt, patient; RA, rheumatoid arthritis; SF-36, Short Form-36 health surveyAcknowledgments:Study sponsored by Pfizer Inc.

Abstract
BACKGROUND AND PURPOSE Despite the improved prognostic relevance of the 2016 WHO molecular-based classification of lower-grade gliomas, variability in clinical outcome persists within existing molecular subtypes. Our aim was to determine prognostically significant metrics on preoperative MR imaging for lower-grade gliomas within currently defined molecular categories. MATERIALS AND METHODS We undertook a retrospective analysis of 306 patients with lower-grade gliomas accrued from an institutional data base and The Cancer Genome Atlas. Two neuroradiologists in consensus analyzed preoperative MRIs of each lower-grade glioma to determine the following: tumor size, tumor location, number of involved lobes, corpus callosum involvement, hydrocephalus, midline shift, eloquent cortex involvement, ependymal extension, margins, contrast enhancement, and necrosis. Adjusted hazard ratios determined the association between MR imaging metrics and overall survival per molecular subtype, after adjustment for patient age, patient sex, World Health Organization grade, and surgical resection status. RESULTS For isocitrate dehydrogenase (IDH) wild-type lower-grade gliomas, tumor size (hazard ratio, 3.82; 95% CI, 1.94-7.75; P < .001), number of involved lobes (hazard ratio, 1.70; 95% CI, 1.28-2.27; P < .001), hydrocephalus (hazard ratio, 4.43; 95% CI, 1.12-17.54; P = .034), midline shift (hazard ratio, 1.16; 95% CI, 1.03-1.30; P = .013), margins (P = .031), and contrast enhancement (hazard ratio, 0.34; 95% CI, 0.13-0.90; P = .030) were associated with overall survival. For IDH-mutant 1p/19q-codeleted lower-grade gliomas, tumor size (hazard ratio, 2.85; 95% CI, 1.06-7.70; P = .039) and ependymal extension (hazard ratio, 6.34; 95% CI, 1.07-37.59; P = .042) were associated with overall survival. CONCLUSIONS MR imaging metrics offers prognostic information for patients with lower-grade gliomas within molecularly defined classes, with the greatest prognostic value for IDH wild-type lower-grade gliomas.
