Abstract
BACKGROUND In Ontario, Canada, patient-reported outcome (PRO) evaluation through the Edmonton Symptom Assessment System (ESAS) has been integrated into clinical workflow since 2007. As stage IV non-small cell lung cancer (NSCLC) is associated with substantial disease and treatment-related morbidity, this province-wide study investigated moderate to severe symptom burden in this population. MATERIALS AND METHODS ESAS collected from patients with stage IV NSCLC diagnosed between 2007 and 2018 linked to the Ontario provincial health care system database were studied. ESAS acquired within 12 months following diagnosis were analyzed and the proportion reporting moderate to severe scores (ESAS ≥4) in each domain was calculated. Predictors of moderate to severe scores were identified using multivariable Poisson regression models with robust error variance. RESULTS Of 22,799 patients, 13,289 (58.3%) completed ESAS (84,373 assessments) in the year following diagnosis. Patients with older age, with high comorbidity, and not receiving active cancer therapy had lower ESAS completion. The majority (94.4%) reported at least one moderate to severe symptom. The most prevalent were tiredness (84.1%), low well-being (80.7%), low appetite (71.7%), and shortness of breath (67.8%). Most symptoms peaked at diagnosis and, while declining, remained high in the following year. On multivariable analyses, comorbidity, low income, nonimmigrants, and urban residency were associated with moderate to severe symptoms. Moderate to severe scores in all ESAS domains aside from anxiety were associated with radiotherapy within 2 weeks prior, whereas drowsiness, low appetite and well-being, nausea, and tiredness were associated with systemic therapy within 2 weeks prior. CONCLUSION This province-wide PRO analysis showed moderate to severe symptoms were prevalent and persistent among patients with metastatic NSCLC, underscoring the need to address supportive measures in this population especially around treatments. IMPLICATIONS FOR PRACTICE In this largest study of lung cancer patient-reported outcomes (PROs), stage IV non-small cell lung cancer patients had worse moderate-to-severe symptoms than other metastatic malignancies such as breast or gastrointestinal cancers when assessed with similar methodology. Prevalence of moderate-to-severe symptoms peaked early and remained high during the first year of follow-up. Symptom burden was associated with recent radiation and systemic treatments. Early and sustained PRO collection is important to detect actionable symptom progression, especially around treatments. Vulnerable patients (e.g., older, high comorbidity) who face barriers in attending in-person clinic visits had lower PRO completion. Virtual PRO collection may improve completion.

Abstract
The naturally occurring cannabis plant has played an established role in pain management throughout recorded history. However, in recent years, both natural and synthetic cannabis-based products for medicinal use (CBPM) have gained increasing worldwide attention due to growing evidence supporting their use in alleviating chronic inflammatory and neuropathic pain associated with an array of conditions. In view of these products' growing popularity in both the medical and commercial fields, we carried out a systematic review to ascertain the effects of cannabis and its synthetically derived products on orofacial pain and inflammation. The application of topical dermal cannabidiol formulation has shown positive findings such as reducing pain and improving muscle function in patients suffering from myofascial pain. Conversely, two orally-administered synthetic cannabinoid receptor agonists (AZD1940 and GW842166) failed to demonstrate significant analgesic effects following surgical third molar removal. There is a paucity of literature pertaining to the effects of cannabis-based products in the orofacial region; however, there is a wealth of high-quality evidence supporting their use for treating chronic nociceptive and neuropathic pain conditions in other areas. Further research is warranted to explore and substantiate the therapeutic role of CBPMs in the context of orofacial pain and inflammation. As evidence supporting their use expands, healthcare professionals should pay close attention to outcomes and changes to legislation that may impact and potentially benefit their patients.

Abstract
BACKGROUND AND PURPOSE To summarize the clinical outcomes of stereotactic body radiotherapy (SBRT) for metastatic breast cancer (mBC) from a large institution. MATERIALS AND METHODS Patients with mBC who received extra-cranial SBRT to metastatic lesions from 2011 to 2017 were identified. Treatment indications were: oligometastases, oligoprogression, and local control of dominant tumor (CDT). Endpoints included overall survival (OS), progression-free survival (PFS), local control (LC) and cumulative incidence of starting/changing chemo or hormonal therapy (SCT). Univariate and multivariate analyses were used to identify predictive factors. RESULTS We analyzed 120 patients (193 treated metastatic lesions) with a median follow up of 15.25 months. 1-and 2-year LC rates were 89% and 86.6%, respectively. 1-and 2-year OS rates were 83.5% and 70%, respectively, with treatment indication and molecular subtype being the predictive factors on MVA. 1-year OS was 91.0%, 78.5% and 63.9% for oligometastases, oligoprogression and CDT, respectively (p = 0.003). The worst OS was seen in basal subtype with 1-and 2-year OS rates of 59.2% and 39.5% (p = 0.01). Treatment indication was found to be predictive for PFS and lower rates of SCT on MVA. 1-and 2-year PFS rates were 45% and 32%, respectively. The 1-year PFS for oligometastases, oligoprogression, and CDT was 66%, 19.6%, and 14.3%, respectively (p < 0.001). The cumulative incidence of SCT at 1-year was 12% for oligometastases, 39.7% for oligoprogression and 53.3% for CDT (p < 0.001). CONCLUSION Patients treated for oligometastases have better OS and PFS than those treated for oligoprogression or CDT. SBRT may delay SCT in mBC patients, particularly those with oligometastases. SBRT provided an excellent LC in mBC patients.

Abstract
12092 Background: Stage IV NSCLC patients have significant disease and treatment-related morbidity. In Ontario, Canada, cancer patients complete Edmonton Symptom Assessment System (ESAS) questionnaires, a tool that elicits patients’ self-reported severity of common cancer-associated symptoms at clinical encounters. ESAS domains are: anxiety, depression, drowsiness, appetite, nausea, pain, shortness of breath, tiredness and well-being. The purpose of this study is to examine moderate-to-severe symptom burden in the 12 months following a diagnosis of stage IV NSCLC. Methods: Using administrative databases and unique encoded identifiers, stage IV NSCLC diagnosed between January 2007 and September 2018 were evaluated for symptom screening with ESAS in the 12 months following diagnosis. Proportion of patients reporting moderate-to-severe score (i.e. ESAS ≥4) in each domain within 12 months were calculated. Patients reporting moderate-to-severe within the different ESAS domains of were plotted over time. Multivariable (MV) Poisson regression models with potential covariates such as age, sex, Elixhauser comorbidity index, income quintiles, and lung cancer treatments received were constructed to identify factors associated with moderate-to-severe symptoms. Results: Of 22,799 stage IV NSCLC patients, 13,289 (58.3%) had completed ESAS (84,373 unique assessments) in the year following diagnosis. Patients with older age, high comorbidity, and not receiving active cancer therapy were less likely to complete ESAS. Most (94.4%) reported at least 1 moderate-to-severe score. Most prevalent moderate-to-severe ESAS symptoms within 12 months after diagnosis were tiredness (84.1%), lack of wellbeing (80.7%), low appetite (71.7%), and shortness of breath (67.8%); nausea was the least prevalent (34.6%). Most symptoms peaked at diagnosis and persisted in the year after diagnosis. On adjusted MV analyses, patients with high comorbidity, low income, and urban residency were associated with increased moderate-to-severe symptoms. Moderate-to-severe scores in all ESAS symptoms were associated with delivery of radiotherapy within 2 weeks prior, while moderate-to-severe nausea, drowsiness, tiredness, low appetite, and lack of wellbeing were associated with delivery of systemic therapy within preceding 2 weeks. Conclusions: In this population-based analysis of stage IV NSCLC PROs in the year following diagnosis, moderate-to-severe symptoms were highly prevalent and persistently high, underscoring the need to address supportive requirements in this at-risk population.

Abstract
Development of brain metastases are common in patients with advanced malignancies leading to significant morbidity and mortality. Although overall survival is an important endpoint in these patients, neurocognition and health related quality of life (HRQoL) more accurately highlights the impact of the disease and its treatment on patients. Whole brain radiotherapy (WBRT) has historically played a key role in the management of these patients, especially those with multiple brain metastases. Clinical trials have supported the use of stereotactic radiosurgery (SRS) alone in patients with limited brain metastases sparing neurocognitive function and HRQoL as compared to the combination of SRS plus WBRT. Furthermore, new systemic agents are increasingly being used in clinical practice and have shown promise in patients with brain metastases. The upcoming clinical trials are tasked with defining treatment guidelines that are more specific to patient and tumour factors incorporating radiation, surgery, and systemic therapy. The validity of findings in these trials rest on the rigor of the study methodology and the utilisation of validated assessment tools for neurocognition and HRQoL. This review aims to appraise and summarise the neurocognitive and HRQoL tools used in modern brain metastases trials.

Abstract
The double whammy of dementia and coronavirus disease 2019 (COVID-19) has raised huge concerns for healthcare systems which are already struggling to cope with care demands of persons with dementia (PWD) in non-pandemic times (1). PWD who are admitted to acute care services are particularly vulnerable to behavioural changes and adverse outcomes from delirium (2, 3). During the COVID-19 period, ward relocation is frequently encountered due to COVID-19 screening and segregation; this constant changing of environment and care teams puts PWD at risk of behavioural exacerbations. This is aggravated by restrictive visitor policies in hospitals, depriving PWD of the reassuring presence of family members. Not surprisingly, caring for persons with dementia (PWD) with behavioral issues in acute care settings has become extremely challenging.

Abstract
OBJECTIVE To elucidate the biological function of microRNA-300 (miRNA-300) in influencing the progression of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS The relative level of miRNA-300 in NSCLC tissues and cells was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The influences of miRNA-300 on the proliferative, migratory, and invasive potentials of A549 cells were assessed. The binding relationship between miRNA-300 and ETS1 was verified by the Dual-Luciferase Reporter Gene Assay. Finally, the regulatory effect of the interactive miRNA-300 and ETS1 on the progression of NSCLC was identified. RESULTS MiRNA-300 was downregulated in NSCLC tissues and cells. The overexpression of miRNA-300 suppressed A549 cells to proliferate, migrate, and invade. MiRNA-300 could bind to ETS1 3'UTR and suppress its level in A549 cells. Notably, the knockdown of miRNA-300 could reverse the regulatory role of ETS1 in the cellular behaviors of NSCLC. CONCLUSIONS MiRNA-300 suppresses NSCLC to proliferate, migrate, and invade by targeting ETS1.

Abstract
Local field potentials (LFPs) may afford insight into the mechanisms of action of deep brain stimulation (DBS) and potential feedback signals for adaptive DBS. In Parkinson's disease (PD) DBS of the subthalamic nucleus (STN) suppresses spontaneous activity in the beta band and drives evoked resonant neural activity (ERNA). Here, we investigate how STN LFP activities change over time following the onset and offset of DBS. To this end we recorded LFPs from the STN in 14 PD patients during long (mean: 181.2 s) and short (14.2 s) blocks of continuous stimulation at 130 Hz. LFP activities were evaluated in the temporal and spectral domains. During long stimulation blocks, the frequency and amplitude of the ERNA decreased before reaching a steady state after ~70 s. Maximal ERNA amplitudes diminished over repeated stimulation blocks. Upon DBS cessation, the ERNA was revealed as an under-damped oscillation, and was more marked and lasted longer after short duration stimulation blocks. In contrast, activity in the beta band suppressed within 0.5 s of continuous DBS onset and drifted less over time. Spontaneous activity was also suppressed in the low gamma band, suggesting that the effects of high frequency stimulation on spontaneous oscillations may not be selective for pathological beta activity. High frequency oscillations were present in only six STN recordings before stimulation onset and their frequency was depressed by stimulation. The different dynamics of the ERNA and beta activity with stimulation imply different DBS mechanisms and may impact how these activities may be used in adaptive feedback.

Abstract
Background:Rheumatoid arthritis (RA) is an autoimmune disease that mainly invades synovial membranes and further damage to articular cartilage and bone. The abnormal activation of transforming-growth factor β (TGF-β) in the subchondral bone is related to the onset of RA joint cartilage degeneration and transforming-growth interacting factor (TGIF) is a negative regulator of TGF-β signaling, while there is no literature addressing the relationship between TGIF polymorphisms and the bone metabolism of RA.Objectives:The aim of the study was to comprehensively explore the possible association for single nucleotide polymorphisms (SNPs) in the TGIF gene with serum bone metabolism markers and RA susceptibility.Methods:Three SNPs within the TGIF gene were genotyped in 155 RA patients and 168 healthy controls by high resolution melting (HRM) analysis in a case-control study. The serum levels of osteocalcin, bone alkaline phosphatase (BALP) and β type I collagen-crosslinked C telopeptide (β-CTX) were detected by electrochemical luminescence in 108 RA patients randomly selected from RA patients group.Results:Genotypes and alleles frequency analysis showed rs7362020 was associated with bone erosion in RA (P=0.012, P=0.003, respectively) and individuals carrying T allele for rs7362020 showed a decreased RA risk (OR=0.59, 95% CI = 0.42-0.84; P= 0.003). In the gender-specific analysis, rs73620203 polymorphism was associated with bone erosion of female RA patients (P values of the distribution of genotypes and alleles were 0.022 and 0.006, respectively). In addition, RA patients with CC, CT and TT genotypes at rs73620203 locus had statistically significant differences in serum osteocalcin and BALP (P=0.006, P=0.037, respectively) and the serum levels in TT genotype RA patients were significantly lower than CC and CT genotype RA patients. The serum levels of β-CTX in rs85440 AA genotype male RA patients were significantly higher than female RA patients (P=0.001), while the serum levels of osteocalcin and BALP in genotype AA, AG and GG female and male RA patients were not significantly different (P all>0.05).Conclusion:Our study provided the first evidence that rs73620203 is associated with bone erosion of RA and provided new insight into the relationship between three SNPs within TGIF gene and regulation of bone metabolism in RA patients of different genders.Acknowledgments:This work was supported by the National Natural Science Foundation of China (Nos. 81772258) and Science and Technology Agency of Sichuan Province (Nos. 2019YFS0310, 2018FZ0106).Disclosure of Interests:None declared

Abstract
Frailty syndrome, caused by degenerative changes in the body and the body vulnerability due to a variety of chronic diseases, is associated with adverse outcomes, such as fall, disability and mortality. With the development of antiretroviral therapy, the average life span of HIV/AIDS patients is extended, the number of elderly living with HIV/AIDS has increased, resulting the increase of the incidence of frailty syndrome in this population. The incidence of frailty syndrome in the elderly is associated with HIV infection and adverse reaction of antiretroviral therapy. Early assessment and intervention of frailty syndrome in elderly HIV/AIDS patients can reduce adverse clinical events and improve the quality of life.

Abstract
Introduction The aim of this study was to evaluate the suitability of using cone‐beam computed tomography (CBCT) obtained with a mobile C‐arm X‐ray fluoroscopy unit as a single modality for planning of high‐dose‐rate (HDR) prostate brachytherapy treatments. Methods The feasibility of using CBCT images obtained using a Siemens Arcadis Orbic 3D mobile C‐arm was evaluated. A retrospective clinical study was undertaken of six participants undergoing HDR prostate brachytherapy. Plans generated using images from a Toshiba Aquilion One LB CT were compared with those generated using CBCT images. After rigid spatial registration, the plans were compared based on various parameters such as dose‐volume histograms, overlap quantities and metrics, and dose constraints. Results Provided they were within the limited field of view, the brachytherapy catheters and fiducial markers were clearly visible in the CBCT images and thus, localisable and identifiable in the treatment planning process. The Siemens CBCT underestimated CT numbers leading to poorer tissue contrast which exacerbated the difficulties in delineation of the target tumour and the surrounding organs at risk. Between CT‐ and CBCT‐based plans, the mean difference of CTV‐D90 was 1.58 Gy, CTV‐V100 was 12.13%, rectum‐V80 was 0.06% and urethra‐V120 was −0.70%. Conclusion It was not feasible to solely utilise the Siemens Arcadis Orbic 3D for HDR prostate brachytherapy treatment planning due to suboptimal organ delineation. However, the methods in this study could be used to evaluate other mobile CBCT imaging devices for feasibility in HDR brachytherapy treatment planning since the results indicated that it may not be necessary to have standard quality CT images for treatment planning.
