Abstract
Artemisia vulgaris L. belongs to Asteraceae, is a herbal plant that has various benefits in the medical field, so that its use in the medical field can be explored optimally, the plant must be thoroughly identified. This study aims to identify A. vulgaris both in terms of descriptive morpho-anatomy and DNA barcoding using BLAST and phylogenetic tree reconstruction. The morpho-anatomical character was observed on root, stem, and leaf. DNA barcoding analysis was carried out through amplification and alignment of the rbcL and matK genes. All studies were conducted on three samples from Taman Husada (Medicinal Plant Garden) Graha Famili Surabaya, Indonesia. The anatomical slide was prepared by the paraffin method. Morphological studies revealed that the leaves of A. vulgaris both on the lower-middle part and on the upper part of the stem have differences, especially in the character of the stipules, petioles, and incisions they have. Meanwhile, from the study of anatomy, A. vulgaris has an anomocytic type of stomata and its distribution is mostly on the ventral part of the leaves. Through the BLAST process and phylogenetic tree reconstruction, the plant sequences being studied are closely related to several species of the genus Artemisia as indicated by a percentage identity above 98% and branch proximity between taxa in the reconstructed phylogenetic tree.

Abstract
Safety regarding herbal products is very necessary; therefore, routine identification of raw materials should be performed to ensure that the raw materials used in pharmaceutical products are suitable for their intended use. In order for the identification-related data obtained to be accurate, the identification of various kinds of markers is also very necessary. The purpose of this study was to describe the characteristics of Eclipta alba (L.) Hassk. based on qualitative morpho-anatomical markers and quantitative DNA coding. The morphology of this plant has herbaceous habit with a taproot and a stem with branches that appear from the middle. Leaves are single type imperfectly arranged oppositely, lanceolatus, finely serrated on the edges, tapered at the base, pointed at the end, and have a pinnate and hairy leaf surface. The flowers consist of ray flowers and tube flowers with a cup shape. Meanwhile, in terms of anatomy, E. alba has aerenchyma, which are scattered in the cortex of the root and stem. In addition, there are anisocytic stomata, glandular trichomes, and non-glandural trichomes with an elongated shape accompanied by ornamentation found on the leaf epidermis. The results of sequence alignment and phylogenetic tree reconstruction show that the sample plants are closely related to species in the genus Eclipta.

Abstract
INTRODUCTION The fourth leading cause of cancer-related mortality and morbidity worldwide is colorectal cancer (CRC). Numerous reasons have contributed to the massive rise in CRC cases, for which Asian nations differ significantly in terms of risk incidence rates. The objectives of this study were to, first, identify the socio-demographic characteristics of those of North Borneo ethnicity and body mass index (BMI) and, second, determine the association of these factors with CRC. This research will contribute to preventing this form of cancer. MATERIALS AND METHODS This study is an analysis of a matched case-control study with a ratio of 1:2. The case group contained 206 respondents, and the control group contained 412. All CRC cases were confirmed with the histological results. The control group was matched for links between age, sex and ethnicity with CRC. The Statistical Package for Social Sciences Statistics (SPSS) IBM version 28.0 was used to conduct descriptive analysis using chi-squared testing and simple logistic regression. The statistical significance was P < 0.05. RESULT Overall, 618 respondents took part in this survey, of which 256 (41.4%) were female and 362 (58.6%) were male. The maximum age was 76, with a mean age ± SD of 53.17 ± 11.4. Those of Bajau ethnicity comprised 24.6% (152) of the population, followed by Dusun with 22.8% (141), Kadazan with 17.6% (109%), other North Borneo ethnic groups with 15.5% (96), Bugis with 9.7% (60), Brunei with 4.4% (27) and other predominant races with 5.3% (33). Regression analyses revealed that the incidence of CRC in North Borneo, Malaysia, was substantially correlated with income, occupation, other linked diseases and BMI. CONCLUSION Various risk factors are linked to CRC, based on the findings related to socio-demographic characteristics and BMI. Therefore, to lower the nationwide prevalence of CRC, national public health campaigns should include collaboration with the regional authorities to highlight the incidence and risk factors of CRC based on ethnicity.

Abstract
NUT midline carcinoma is a rare malignancy most commonly seen in adolescents and young adults. The disease presents most often in the lung or head and neck area but can be seen occasionally elsewhere. The diagnosis can be difficult and requires a high degree of suspicion with demonstration of the classic fusion rearrangement mutation of the NUTM1 gene with one of a variety of partners by immunohistochemistry, fluorescent in situ hybridization, or genomic analysis. Survival is usually only a number of months with few long-term survivors. Here we report one of the longest-known survivors of this disease treated with surgery and radiation without additional therapy. Systemic treatment approaches including the use of chemotherapy and BET and histone deacetylase inhibitors have yielded modest results. Further studies of these, as well as p300 and CDK9 inhibitors and combinations of BET inhibitors with chemotherapy or CDK 4/6 inhibitors, are being evaluated. Recent reports suggest there may be a role for immune checkpoint inhibitors, even in the absence of high tumor mutation burden or PD-L1 positivity. RNA sequencing of this patient's tumor demonstrated overexpression of multiple potentially targetable genes. Given the altered transcription that results from the causative mutation multi-omic evaluation of these tumors may uncover druggable targets for treatment.

Abstract
The aim of this study was to determine the incidence of postoperative cerebrovascular accident (CVA) following head and neck free tissue transfer and to identify predictive risk factors. A retrospective audit was performed of patients who underwent head and neck reconstructive surgery at Queen Elizabeth University Hospital between 2009 and 2020. The patient records were analysed to identify those who developed CVA within 30 days after surgery. A total of 1109 patients underwent head and neck free tissue transfer surgery, including 1048 neck dissection procedures. Of these, 78.6% had one or more identified risk factors for perioperative stroke. Five patients (0.45%) developed postoperative CVA. The results showed that CVA correlated to patients with hypercholesterolemia (P = 0.007). This study demonstrates the safety of free tissue transfer. Despite underlying co-morbidities and risk factors, the incidence of CVA is low following surgery and manipulation of the major vasculature of the neck.

Abstract
BACKGROUND Despite having a similar prevalence to Western populations, literature on chronic rhinosinusitis (CRS) in the Asian population is sparse. There is limited data on the epidemiology and aetiology of CRS in Asia. OBJECTIVES To review the current literature on the epidemiology and aetiology of CRS in Asia. METHODS This is a narrative review of published data on the epidemiology and aetiology of CRS. Studies on CRS in Asian countries, published in English and indexed on PubMed or Google Scholar were reviewed. Where available, data extracted included epidemiology, endotype and cytokine profiles and genetic profiles. RESULTS AND CONCLUSION The prevalence of CRS in Asia ranges widely from 2.1% to 28.4%. Type 2 inflammation has been reported in 5%-55% of Asian patients, with lower levels of Type 2 cytokines reported in head to head comparisons of Western versus Asian patients. Notably, there exists marked heterogeneity in criterion of the tissue eosinophilic infiltration for diagnosis of type 2 CRS. Our review suggests that differences in prevalence of CRS and proportion of eosinophilic CRS between Asia and Europe and the Americas requires further study. Large-scale Asian studies utilising standardised definitions are needed to bridge this gap. Head to head genetic and microbiomal analysis may also be useful in understanding differences in CRS between the Asian and Western populations.

Abstract
BACKGROUND Cerebrospinal fluid (CSF) rhinorrhea requires proper management to avoid disastrous consequences. The objectives of this study were to ascertain the patient characteristics, etiologies, sites of defect, skull base configurations, methods of investigation, and management outcomes of CSF rhinorrhea. METHODS A retrospective study was performed over 4 years involving three surgeons from Malaysia, Singapore, and Thailand. Hospital records were reviewed to determine the patients' characteristics, the causes and sites of leaks, methods of investigation, skull base configurations, choices of treatment, and outcomes. RESULTS A total of 15 cases (7 traumatic and 8 non-traumatic) were included. Imaging was performed in all cases. The most common site of leakage was the cribriform plate (9/15 cases). The mean ± SD of the Keros heights were 4.43 ± 1.66 (right) and 4.21 ± 1.76 mm (left). Type II Keros was the most common (60%). The mean ± SD angles of the cribriform plate slope were 51.91 ± 13.43 degrees (right) and 63.54 ± 12.64 degrees (left). A class II Gera configuration was the most common (80%). All except two patients were treated with endonasal endoscopic surgical repair, with a success rate of 92.3%. A multilayered repair technique was used in all patients except one. The mean ± SD postoperative hospital stay was 9.07 ± 6.17 days. CONCLUSIONS Non-traumatic CSF rhinorrhea outnumbered traumatic CSF rhinorrhea, with the most common site of leak at the cribriform plate. Imaging plays an important role in investigation, and Gera classification appears to be better than Keros classification for evaluating risk. Both conservative and surgical repairs are practiced with successful outcomes. Endonasal endoscopic CSF leak repair is the mainstay treatment.

Abstract
Abstract
Background
A remote hypertension (HTN) program, designed and implemented at Mass General Brigham (MGB), has demonstrated improved HTN control, reduced need for in-person visits, and increased access to care. The program excluded patients with resistant HTN or multiple intolerances/allergies to guideline-directed therapies, whose blood pressure (BP) is difficult to manage.
Purpose
To develop a more intensive but still remote program (“HTN-Plus”) for patients with resistant HTN or intolerances/allergies to multiple medications, and to assess its effectiveness for BP control.
Methods
From 10/2020 through 11/2021, we identified a subset of hypertensive patients from the total pool of those enrolled in our remote HTN management program, who required more personalized and intensive therapy than the overall remote management program provided. We developed ancillary management for these patients, who included: 1) patients with apparent resistant HTN (ARH), ie with uncontrolled BP despite maximum tolerated doses of at least three anti-HTN medications including a diuretic, and 2) patients with multiple medication intolerances or allergies that precluded appropriate triple therapy or limited dose-optimization. A nurse practitioner provided education and advice on BP measurement technique, lifestyle modifications, and adherence. Evaluation for primary aldosteronism (PA) was undertaken in those with ARH.
Results
We enrolled 3658 patients with uncontrolled HTN, of whom 117 qualified for the HTN-Plus program. The average BP on entry was 143/80 mmHg. 68% had apparent resistant HTN and 32% had multiple medication intolerances/allergies. Among all patients, 30% had incorrect BP-measurement technique upon interview, 10% who were tested for PA had a positive screening test, 56% had a history suggestive of an unmanaged secondary cause, and only 6% admitted imperfect adherence, but urine testing was not done. 74% of patients completed the program meaning they were reachable through the end and did not drop out. Across the program, 72 new medications were started, and 84 medication titrations were made. 50% of patients who enrolled in HTN-plus achieved BP <130/80 mmHg. 22% achieved BP control with education and coaching alone. For patients who completed the program, the average entry and final BPs were 139/78 mmHg and 126/70 mmHg respectively, with an average BP decrease of 13/8 mmHg.
Conclusions
In patients who remain hypertensive despite maximally tolerated guideline-directed medication utilization, our intensified but still entirely remote HTN management program helped patients reach their BP goal through education, coaching, and medication management. Nearly a quarter were able to achieve BP control with education and coaching alone. These results suggest that a significant value of remote care in patients with resistant HTN or medication intolerances/allergies lies in ongoing education and coaching, for which more cost-effective solutions may be considered.

Abstract
Abstract
Purpose: Multi-tyrosine kinase inhibitors have shown clinical activity in metastatic colorectal cancer patients. Cabozantinib, a multi-tyrosine kinase inhibitor, exhibited potent antitumor activity superior to regorafenib in preclinical colorectal cancer patient-derived tumor xenograft models. This Phase II study aimed to investigate cabozantinib, a multityrosine kinase inhibitor, in refractory, metastatic colorectal cancer patients. Patients and Methods: A non-randomized, two-stage, phase 2 clinical trial evaluating 12 week PFS was conducted in 8 cancer centers across the United States between May 2018 and July 2020. Results: A total of 44 patients were enrolled between May 2018-May 2019, 40 of which were response evaluable. Of the total 769 reported adverse events (AE), 93 (12%) were ≥ grade 3. Five Grade 5 AEs were reported of which 4 were unrelated to study drug and 1 was reported as possibly related due to bowel perforation. Eighteen patients (45%) achieved 12-week PFS with stable disease or better (CI 0.29-0.62; p<0.001). One patient (3%) had a partial response, and 27 other patients achieved stable disease as best response per RECISTv1.1. Median PFS was 3.0 months, and median OS was 8.3 months. Of the 18 patients who achieved 12-week PFS, 12 had left-sided primary tumors, 11 were RAS wild type,11 were PIK3CA wild type, and 6 had previous regorafenib therapy. The 12-week PFS rate was higher in RAS wild type tumors compared to RAS mutant tumors (0.61 vs 0.32, p=0.11). Conclusions: This phase 2 study demonstrated clinical activity of cabozantinib in heavily pretreated, refractory mCRC patients, and supports further investigation.

Abstract
BACKGROUND Brain health is essential for health, well-being productivity and creativity across the entire life. Its definition goes beyond the absence of disease embracing all cognitive, emotional, behavioural and social functions which are necessary to cope with life situations. METHODS The EAN Brain Health Strategy responds to the high and increasing burden of neurological disorders. It aims to develop a non-disease, non-age centred holistic and positive approach ('one brain, one life, one approach') to prevent neurological disorders (e.g., Alzheimer's disease and other dementias, stroke, epilepsy, headache/migraine, Parkinson's disease, multiple sclerosis, sleep disorders, brain cancer) but also to preserve brain health and promote recovery after brain damage. RESULTS The pillars of the EAN Brain Health strategy are: 1) Contribute to a global and international Brain Health approach (together with national and subspecialty societies, other medical societies, WHO, WFN, patients' organizations, industry, and other stakeholders); 2) Supporting the 47 European national societies, healthcare and policymakers in the implementation of integrated and people-centred campaigns; 3) Fostering Research (e.g. on prevention of neurological disorders, determinants and assessments of brain health), 4) Promoting Education of students, neurologists, general practitioners, other medical specialists and health professionals, patients, caregivers, and general public; 5) Raising public awareness of neurological disorders and brain health. CONCLUSIONS By adopting this 'one brain, one life, one approach' strategy in cooperation with partner societies, international organisations, and policymakers, a significant number of neurological disorders may be prevented while enhancing the overall well-being of individuals by maintaining brain health through the life course.

Abstract
INTRODUCTION Extra-skeletal Ewing sarcoma - a rare clinical entity. After the tumour resection, a huge upper anterior abdominal wall defect poses a challenge in soft tissue reconstruction in a thin individual. CASE PRESENTATION We report an anterior abdominal wall Ewing sarcoma in a 22-year-old gentleman, arising from the left rectus abdominis muscle. After wide local excision, the reconstruction was achieved with free anterolateral thigh(ALT) fasciocutaneous flap with arteriovenous(AV) loop graft, right medial intercostal artery perforator(MICAP) flap and split-thickness skin graft(SSG). DISCUSSION The goals of anterior abdominal wall reconstruction are to restore the integrity of the abdominal wall, prevent visceral eventration, and provide functional support. In view of the size of the defect, a free ALT flap was harvested and anastomosed to the left deep inferior epigastric bundle with the AV loop graft. Although the current trend is skewed towards the use of biologic mesh, an on-lay prolene mesh was used due to its affordable cost and that the biologic mesh was not available in Malaysia. The options of further reconstruction after the patient developed marginal flap necrosis and surgical site infection were also discussed. Post-operation 3 months, there was denser hair growth on the ALT flap. This finding has never been reported before and warrants further studies. CONCLUSION The use of combination of various technique, namely free ALT fasciocutaneous flap with AV loop graft, right MICAP flap and SSG in reconstruction ensures a satisfactory functional and aesthetic outcome in the upper anterior abdominal wall reconstruction.

Abstract
The British Association of Oral and Maxillofacial Surgery is soon to implement the Quality Outcomes in Oral in Maxillofacial Surgery (QOMS) to provide a platform for quality management across the specialty in the UK. The initial oncology and reconstruction audits for QOMS involves data collection on specific procedures and metrics. The aim of this report is to determine their appropriateness using extant audit datasets in our institution that overlap substantially with the QOMS audits. Pre-existing datasets comprising information on patients treated for oral cavity SCC with curative intent were analysed. Data on surgical margins, lymphadenectomy lymph node yield, delay between surgery and adjuvant radiotherapy, duration of hospital stay, and complications including flap failures were analysed. All statistical analyses were performed with SPSS 25. Run charts describing longitudinal data were generated using SPC for Excel version 6. Twenty three patients (3.1%) of 701 resections had a positive surgical margin reported. Seventeen (4.3%) of patients had less than 18 LNs in the ND specimen analysed. Mean time to start date of adjuvant therapy was 62 days. Only 9% of patients commenced adjuvant therapy within 6 weeks. The median duration of stay was 18 days. In 1153 free flaps a failure rate of 4.3% was identified. A total of 1349 complications (CD I-V) were recorded in the 1111 patients undergoing major surgery with free flap reconstruction. The QOMS selected metrics for oncology and reconstruction are clinically relevant, readily measurable, and likely to be actionable by the surgical team.

Abstract
e21008 Background: NUT midline carcinoma (NMC) is an aggressive squamous cell carcinoma molecularly defined by a chromosomal rearrangement of nuclear protein in testis (NUTM1) with bromodomain-containing protein 3 or 4 (BRD3/4). While NMCs are characterized by this rare canonical gene rearrangement little is known about the transcriptome and proteosome of this rare disease. As such, we set out to comprehensively characterize five NMC cases in which we attained targeted DNA sequencing, full-transcriptome RNA sequencing, and targeted proteomics. We further examine and integrate these results in order to better understand the relationship between gene expression and protein abundance within the context of NMC. Methods: All cases were analyzed for genomic and transcriptomic alterations against a custom panel via the Tempus xT tissue biopsy assay (DNA sequencing of 648 genes in tumor and matched normal samples at 500x depth and full-transcriptome RNA sequencing) for germline and/or somatic mutations. The xT assay detects single nucleotide variants, specific insertion/deletions, amplifications and gene fusions, as well as tumor mutational burden (TMB) and microsatellite instability (MSI) status. Proteomic data were obtained utilizing digital spatial profiling through Nanostring immune, MAPK and PI3/AKT, and pan tumor nCounter GeoMix panels. Results: Clinical characteristics, histology, and genomic/proteomic alterations for 5 NMC cases are presented. Cases were defined by pathological assessment and the identification of the canonical NUTM1 fusion, further broken down by fusion partner with three patients having NUTM1-BRD4 fusions, one NUT-BRD3, and one NUT-ZMYND8. TMBs ranged for 0.8-.6 mutations/megabases (n=5). All patients were MSI stable (5/5). Of three patients with available PD-L1 IHC result, one had elevated PD-L1 tumor staining at 70%. Results will be presented from full-transcriptome RNA expression analysis indicating overexpression of BRAF, MYC, mTOR, and EGFR, among others. Targeted proteomics were performed to assess relative abundance at the protein level (results to be presented). Clinical follow up for the five patients revealed that two have survived beyond 7 months. A lung primary patient treated with surgical resection and post op radiation (XRT) is NED at 63 months. A sinus primary patient is NED at 16 months after a partial response (PR) to taxotere/5FU/Cisplatin followed by resection and XRT/cis platin. One patient had a brief PR from ifosphamide/etoposide/vorinostat. One patient's tumor grew through XRT/cisplatin. Conclusions: Multi-omic analysis has the potential to further elucidate the mechanisms of tumor growth in NMC and identify new targets for the treatment of this aggressive and poor prognosis disease.

Abstract
Understanding the mechanisms of myogenesis in human induced pluripotent stem cells (hiPSCs) is a prerequisite to achieving patient-specific therapy for diseases of skeletal muscle. hiPSCs of different origin show distinctive kinetics and ability to differentiate into myocytes. To address the unique cellular and temporal context of hiPSC differentiation, we perform a longitudinal comparison of the transcriptomic profiles of three hiPSC lines that display differential myogenic specification, one robust and two blunted. We detail temporal differences in mechanisms that lead to robust myogenic specification. We show gene expression signatures of putative cell subpopulations and extracellular matrix components that may support myogenesis. Furthermore, we show that targeted knockdown of ZIC3 at the outset of differentiation leads to improved myogenic specification in blunted hiPSC lines. Our study suggests that β-catenin transcriptional cofactors mediate cross-talk between multiple cellular processes and exogenous cues to facilitate specification of hiPSCs to mesoderm lineage, leading to robust myogenesis.

Abstract
Background Olfactory dysfunction (OD) has been gaining recognition as a symptom of COVID-19, but its clinical utility has not been well defined. Objectives To quantify the clinical utility of identifying OD in the diagnosis of COVID-19 and determine an estimate of the frequency of OD amongst these patients. Methods PubMed was searched up to 1 August 2020. Meta-analysis A included studies if they compared the frequency of OD in COVID-19 positive patients (proven by reverse transcription polymerase chain reaction) to COVID-19 negative controls. Meta-analysis B included studies if they described the frequency of OD in COVID-19 positive patients and if OD symptoms were explicitly asked in questionnaires or interviews or if smell tests were performed. Results The pooled frequency of OD in COVID-19 positive patients (17,401 patients, 60 studies) was 0.56 (0.47–0.64) but differs between detection via smell testing (0.76 [0.51–0.91]) and survey/questionnaire report (0.53 [0.45–0.62]), although not reaching statistical significance (p = 0.089). Patients with reported OD were more likely to test positive for COVID-19 (diagnostic odds ratio 11.5 [8.01–16.5], sensitivity 0.48 (0.40 to 0.56), specificity 0.93 (0.90 to 0.96), positive likelihood ratio 6.10 (4.47–8.32) and negative likelihood ratio 0.58 (0.52–0.64)). There was significant heterogeneity amongst studies with possible publication bias. Conclusion Frequency of OD in COVID-19 differs greatly across studies. Nevertheless, patients with reported OD were significantly more likely to test positive for COVID-19. Patient-reported OD is a highly specific symptom of COVID-19 which should be included as part of the pre-test screening of suspect patients.

Abstract
Complete tumour resection (R0 margin) is an axiom of surgical oncology. Oral cancer ablation is challenging, due to anatomical, functional, and aesthetic considerations. R0 margin is strongly linked to better survival outcomes with great variation in the R0 % across units. This is commonly attributed to disease biology. Without disputing the importance of biological characteristics, we contend that image-based anatomical surgical planning has an important role to play in achieving complete resection. Here, we present our approach utilising cross-sectional imaging, anatomical characteristics and spatial awareness in planning resections for floor of mouth (FOM) and oral tongue cancers. We highlight the challenge of controlling the deep tumour margin lingual to mandible due to anterior vector constraints and emphasise the importance of resecting the genial muscles in a planned fashion and that any rim resection should be obliquely sagittal. In resecting lateral FOM tumours, assessing extension to the parapharyngeal fat is crucial; and mandibular rim resection at a sagittal plane below the mylohyoid line is often required. Assessing the proximity of the contralateral neurovascular pedicle, pre-epiglottic space and hyoid bone are crucial parameters to determine the extent of tongue tumour resection. Our cohort included 173 patients with FOM SCC and 299 patients with tongue SCC. Six patients (3.5%) from the FOM group and eight patients (3%) from the tongue group had involved (R1) margins following surgery. This was associated with local relapse (p<0.05). In conclusion, we demonstrate that image-based planning can aid achieving R0 resections and reduce disease relapse.

Abstract
AIMS To identify Botryosphaeriaceae fungal species that are associated with stem-end rot of mango, and to study their pathogenicity on mango fruit. METHODS AND RESULTS Based on the sequences of internal transcribed spacer (ITS), TEF1-α and β-tubulin, as well as on the phylogenetic analysis of combined sequences, four species of Lasiodiplodia (L. theobromae,L. pseudotheobromae, L. iranensis, L. mahajangana) and two species of Neofusicoccum (N. ribis, N. parvum) were identified. Pseudofusicoccum violaceum, Neoscytalidium dimidiatum and three species of Botryosphaeria (B. scharifii, B. dothidea, B. ramosa) were identified based on sequences of ITS and TEF1-α. Pathogenicity test of selected isolates were tested on Chok Anan, Waterlily and Falan mango cultivars. Generally, all species were observed to be pathogenic on the three tested mango cultivars on wounded fruits, except for N. ribis and N. parvum, which were pathogenic on both wounded and unwounded fruits. However, N. ribis was only pathogenic on cultivar Falan, whereas B. ramosa were pathogenic on cultivars Waterlily and Falan. CONCLUSIONS Eleven species of Botryosphaeriaceae were associated with mango stem-end rot in Malaysia. To the best of our knowledge, four species, namely L. mahajangana, B. ramosa, N. ribis and P. violaceum are the first recorded Botryosphaeriaceae fungi associated with stem end rot of mango. SIGNIFICANCE AND IMPACT OF THE STUDY The identification of Botryosphaeriaceae fungi is important to establish suitable control measures and quarantine requirements. Many species have a wide host range, which means that there is a possibility of cross infection from other infected plants.

Abstract
BACKGROUND Expanded endonasal approaches have the potential to injure the abducens nerve (cranial nerve [CN] VI). The nerve's root entry zone (REZ) and cisternal segment (CS) are particularly prone to injury during the clivus resection and dural incision of transclival approaches. OBJECTIVE To investigate the role of the eustachian tube (ET) as a surgical landmark for the REZ and CS of CN VI. METHODS Transclival expanded endonasal approaches were performed bilaterally in 6 fresh-frozen cadaveric specimens (12 sides). Anatomic relationships between ET and CN VI were documented with neuronavigation. RESULTS The mean vertical distance from the inferior brainstem point to the horizontal projection of CN VI REZ, CS midpoint, and interdural segment (ID) were 26.38 mm (95% confidence interval [CI] 17.36-35.4), 38.61 mm (95% CI 25.61-51.61), and 42.68 mm (95% CI 30.14-55.22), respectively. The relative vertical distance from the ET to the horizontal projections of the REZ, CS midpoint, and its ID were 6.43 mm (95% CI 3.25-9.61), 18.66 mm (95% CI 11.52-25.8), and 22.72 mm (95% CI 16.02-29.42), respectively. In the axial plane the angles between the ET and (1) the REZ and its midline horizontal projection point, (2) the midpoint and its midline horizontal projection point, and (3) ID and its midline horizontal projection point were 9.81 ± SD 5.20°, 18.50 ± SD 4.87°, and 24.71 ± SD 6.21°, respectively. CONCLUSION The ET may serve as a constant landmark to reliably predict the position of the REZ and CS of CN VI.

Abstract
103 Background: Therapeutic resistance to antiangiogenics in metastatic colorectal cancer (mCRC) inevitably develops via multiple mechanisms including upregulation of the MET kinase pathway. Cabozantinib, an oral multityrosine kinase inhibitor targeting MET, AXL, and VEGFR, demonstrated significant anti-tumor activity in CRC xenograft and cell line models. Methods: A single-arm, two-stage phase II study was conducted at 7 AGICC centers nationwide. 44 patients (pts) with mCRC who had progressed on or were intolerant of standard of care agents were treated with cabozantinib 60 mg daily in q3 wk cycles. The primary endpoint was 12-wk PFS rate. Based on the control arm of phase III CORRECT study, the Kaplan-Meier 12-wk PFS rate estimate was 13% and served as the null hypothesis. This study was powered at 0.906 to detect the alternative hypothesis of 12-wk PFS rate of 33% with a type I error rate of 0.044. Secondary endpoints were safety, RR, OS, and retrospective analysis of PFS and RR based on RAS, BRAF, and PIK3CA mutation status. Results: 44 pts were enrolled and 34 pts were response-evaluable as having undergone at least the first 6-wk restaging scan. 10 pts discontinued treatment prior to the first 6-wk scan due to clinical disease progression. Median number of cycles was 4 and median follow-up was 2.5 months. As of data-cutoff 8/23/2019, 55 Grade 3/4 AEs were reported with the most common being hypertension, fatigue, diarrhea, pain, HFS, nausea, vomiting, and proteinuria. 32 SAEs occurred in 18 pts. 5 Grade 5 AEs were reported: disease progression (3), disseminated intravascular coagulopathy, and bowel perforation. 15 pts (34%) achieved ≥ 12-wk PFS and 8 patients remain on treatment. Best response was 1 PR and 31 SD with a DCR at 6 wks of 72.7%. Of the pts who achieved ≥ 12-wk PFS, 12 had left-sided primary tumors, 5 had a RAS mutation, 1 had a PIK3CA mutation, and all pts were BRAF WT and MSI stable. Conclusions: Cabozantinib was deemed safe and demonstrates encouraging efficacy in a heavily pretreated mCRC pt population. These results support further investigation of cabozantinib in mCRC. Clinical trial information: NCT03542877.

Abstract
OBJECTIVES To determine if the volume of buccal fat, ascertained by computed tomography (CT) scanning, would correspond to surface area and reach (length and width) of the flap intraoperatively to aid in the reconstruction of selected skull base defects. METHODS Cadaveric study of five specimens, 10 sides. Methods CT imaging and evaluation using the Osirix 9 software (Pixmeo; Bernex, Switzerland). of cadaveric heads to calculate the volume of the buccal fat bilaterally. The flap was then harvested endoscopically. Measurements were taken. Two heads were also dissected via a transfacial approach. RESULTS The volume of the buccal fat pad (BFP) as well as the maximum length and width of the endoscopically harvested flap were documented. There was a positive correlation shown between the calculated volume of the BFP based on CT imaging and the dissected length and width of the flap (Pearson correlation, r = 0.83 and r = 0.80, respectively). The transfacial dissection demonstrated the lobes of the BFP well, showing that most of the endoscopic mobilization of the BFP was limited to the posterior lobe, in particular to the temporalis and pterygoid components, with minimal displacement of the superficial components. This minimized the risk of visibly hollowing the buccal fullness. CONCLUSION Preoperative calculation of the CT-based volume of the BFP correlates positively with the intraoperative maximum reach of the flap for both length and width. Whereas the volume may be lower in some instances, the BFP would still have adequate reach to provide coverage for the lower and mid-clival region in most patients. LEVEL OF EVIDENCE NA.

Abstract
BACKGROUND AND AIMS Inflammatory bowel disease is associated with an increased risk of colorectal cancer, with estimates ranging 2-18%, depending on the duration of colitis. The management of neoplasia in colitis remains controversial. Current guidelines recommend endoscopic resection if the lesion is clearly visible with distinct margins. Colectomy is recommended if complete endoscopic resection is not guaranteed. We aimed to assess the outcomes of all neoplastic endoscopic resections in inflammatory bowel disease. METHODS This was a multicentre retrospective cohort study of 119 lesions of visible dysplasia in 93 patients, resected endoscopically in inflammatory bowel disease. RESULTS A total of 6/65 [9.2%] lesions <20 mm in size were treated by ESD [endoscopic submucosal dissection] compared with 59/65 [90.8%] lesions <20 mm treated by EMR [endoscopic mucosal resection]; 16/51 [31.4%] lesions >20 mm in size were treated by EMR vs 35/51 [68.6%] by ESD. Almost all patients [97%] without fibrosis were treated by EMR, and patients with fibrosis were treated by ESD [87%], p < 0.001. In all, 49/78 [63%] lesions treated by EMR were resected en-bloc and 27/41 [65.9%] of the ESD/KAR [knife-assisted resection] cases were resected en-bloc, compared with 15/41 [36.6%] resected piecemeal. Seven recurrences occurred in the cohort. Seven complications occurred in the cohort; six were managed endoscopically and one patient with a delayed perforation underwent surgery. CONCLUSIONS Larger lesions with fibrosis are best treated by ESD, whereas smaller lesions without fibrosis are best managed by EMR. Both EMR and ESD are feasible in the management of endoscopic resections in colitis.

Abstract
CRLX101 is a nanoparticle-drug conjugate with a camptothecin payload. We assessed the toxicity and pathologic complete response (pCR) rate of CRLX101 with standard neoadjuvant chemoradiotherapy (CRT) in locally advanced rectal cancer. A single-arm study was conducted with a 3 + 3 dose escalation phase Ib followed by phase II at the maximum tolerated dose (MTD). Thirty-two patients were enrolled with 29 (91%) patients having T3/4 and 26 (81%) N1/2 disease. In phase Ib, no patient experienced a dose limiting toxicity (DLT) with every other week dosing, while 1/9 patients experienced a DLT with weekly dosing. The weekly MTD was identified as 15 mg/m2. The most common grade 3-4 toxicity was lymphopenia, with only 1 grade 4 event. pCR was achieved in 6/32 (19%) patients overall and 2/6 (33%) patients at the weekly MTD. CRLX101 at 15 mg/m2 weekly with neoadjuvant CRT is a feasible combination strategy with an excellent toxicity profile. Clinicaltrials.gov registration NCT02010567.

Abstract
Background The management of optic nerve sheath meningiomas (ONSMs) remains controversial. Surgical decompression through traditional resective techniques has been associated with significant morbidity. While radiation therapy, the current modality of choice is not exempt of risks. Transnasal endoscopic optic nerve decompression (EOND) offers a direct route to the orbit, optic canal, and orbital apex, providing a minimally invasive alternative. Objective The main objective of this article is to assess EOND as the initial management of symptomatic patients with primary ONSM. Methods Patients with ONSMs without a history of radiotherapy who underwent EOND were retrospectively reviewed. Postoperative imaging, duration of follow-up, and visual outcomes at the last ophthalmology visit were assessed. Results Four women (age range 25-63 years) with primary ONSMs that underwent EOND were identified. All patients displayed subjective and objective baseline signs of vision loss. Additionally, baseline proptosis, diplopia, optic nerve atrophy, and ocular pain were identified. In none of the cases, the optic nerve sheath was breached. Following EOND, all patients deferred treatment with adjuvant radiotherapy. At a mean postoperative follow-up of 14 months, all patients were clinically stable without evidence of disease progression on imaging or physical examination. At last ophthalmologic evaluation, three out of four showed objective improvements from baseline visual acuity and visual field (remaining patient had baseline optic nerve atrophy). Conclusion These results suggest that EOND could be a viable initial treatment modality of selected primary ONSM cases. Further studies are warranted to determine long-term efficacy and its role in a stepwise progression of management, preceding radiotherapy.

Abstract
Precision medicine is at the forefront of innovation in cancer care. With the development of technologies to rapidly sequence DNA from tumors, cell-free DNA, proteins, and even metabolites coupled with the rapid decline in the cost of genomic sequencing, there has been an exponential increase in the amount of data generated for each patient diagnosed with cancer. The ability to harness this explosion of data will be critical to improving treatments for patients. Precision medicine lends itself to big data or "informatics" approaches and is focused on storing, accessing, sharing, and studying these data while taking necessary precautions to protect patients' privacy. Major cancer care stakeholders have developed a variety of systems to incorporate precision medicine technologies into patient care as soon as possible and also to provide the ability to store and analyze the omics and clinical data aggregately in the future. Scaling these precision medicine programs within the confines of health care system silos is challenging, and research consortiums are being formed to overcome these limitations. Incorporating and interpreting the results of precision medicine sequencing is complex and rapidly changing, necessitating reliance on a group of experts. This is often performed at molecular tumor boards at large academic and research institutions with available in-house expertise, but alternative models clinical decision support software or of virtual tumor boards potentially expand these advances to almost any patient, regardless of site of care. The promises of precision medicine will be more quickly realized by expanding collaborations to rapidly process and interpret the growing volumes of omics data.

Abstract
Background: Cancer survivorship as an area, which focuses on the health and life of an individual following cancer diagnosis and treatment is increasingly being recognized as an important component of the cancer control continuum. Advances in breast cancer detection and treatments have resulted in a growing number of patients experiencing a breast cancer diagnosis at an age when career plays an important role in their lives. Yet, very little is known on how breast cancer affects employment and return to work among survivors, particularly in low- and middle-income settings. Aim: This qualitative study aims to gain an in-depth understanding on employment challenges and motivators/barriers in return to work faced by breast cancer survivors in an upper-middle income Asian setting. Methods: Eleven focus group discussions (FGDs) were conducted with breast cancer survivors representing various ethnicities and socioeconomic backgrounds in Malaysia. Patients diagnosed one to two years prior to the study were recruited from a general public hospital, a public academic hospital and two private hospitals. Data from the FGDs were examined using thematic content analysis from the NVivo software. Results: The major themes relating to impact of cancer diagnosis on employment were “decreased work ability”, “job loss”, “long absenteeism” and “hostile work environment”. Coping strategy themes frequently mentioned to offset income loss from employment changes were “savings”, “part-time work” or financial support from “family/friends” or “social security”. However, participants were quick to highlight the insufficiency and unreliability of these strategies to cope financially in the long run. When describing their decision in choosing to return to work, participants mentioned themes such as “need money”, feeling “more happy” or having a “supportive work environment”. Nonetheless, participants emphasized the “discrimination” they faced in finding a job after active treatment. Specifically, participants' frequent need to take time-off from work for their cancer follow-ups as well as their older age were perceived as disadvantages in seeking employment when compared with younger, healthy applicants. Conclusion: It is evident that a breast cancer diagnosis severely disrupts employment and return to work in middle income settings. Multisectoral interventions are urgently required to improve the employment status of our cancer survivors, including legislative reforms to prevent discrimination. Programs supporting employment and return to work among cancer survivors should be developed and integrated in the provision of a holistic survivorship care.

Abstract
Background: Worldwide surveys suggest that the use of CAM is becoming increasingly popular among the general population as well as among cancer patients. Aim: We determined the patterns of complementary and alternative medicine (CAM) use in cancer patients, and the associated factors in a multiethnic Asian setting. Methods: Through the Asean CosTs In ONcology (ACTION) prospective cohort study, 1662 newly diagnosed cancer patients were recruited from 12 public and 2 private hospitals in Malaysia. In the current study, we only included 1328 patients who were alive and completed one-year of follow-up. Using questionnaires and cost diaries, patients' sociodemographic factors and disease related factors were measured at baseline, whereas details on CAM use were measured at 12 months. Results: Median age at cancer diagnosis was 53 years. Patients comprised those with breast cancer (33%), gastrointestinal cancers (27%), hematologic malignancies (22%), female reproductive cancers (6%), respiratory cancers (5%), and other types. At one-year, 175 patients reported using CAM (14%), of which 53 comprised patients reporting inability to make necessary household payments (economic hardship) at initial diagnosis. Most CAM users took food or nutritional supplements (75%), spending between RM150 to RM7500 in a year, followed by traditional local medicine (43%), where expenditures ranged between RM50 to RM20,000. A minority practiced homeopathy, and mind-body practices. Fifty-one patients used more than one type of therapy. In CAM users with economic hardship at baseline, median expenditure on CAM was RM1500, with some spending as much as RM10,000. Compared with other cancer types, patients with hematologic malignancies and women with breast cancer were most likely to use CAM. In a multivariable analysis, baseline factors that were associated with CAM use were economic hardship, higher anxiety scores, having female reproductive cancers, or hematologic malignancies, receipt of surgery, and nonreceipt of radiotherapy. Sex, education status, marital status, health insurance status, cancer stage, and systemic cancer therapy do not appear to be associated with CAM use. Conclusion: While the proportion of patients reporting CAM use following a cancer diagnosis appear low in this study, the finding that patients with initial economic hardship were independently more likely to use CAM, warrants attention.

Abstract
BACKGROUND Yogic stretching (asana) has been proven to have an effect on salivary human beta-defensin-2 (HBD-2) concentration, which is an antimicrobial peptide and is an inflammatory marker in periodontal disease. Sudarshan Kriya Pranayama (SKP) is a part of yoga which involves rhythmic breathing. Hence, we aim to evaluate the periodontal parameters and to estimate the salivary HBD-2 level before and after SKP program in periodontitis individuals. MATERIALS AND METHODS An interventional study was designed and individuals were divided into three groups: Group I - healthy periodontium, Group II - chronic gingivitis, and Group III - chronic periodontitis. SKP was the interventional tool. The clinical parameters such as plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and salivary HBD-2 level were analyzed at baseline and 90 days after the SKP practice. Enzyme-linked immunosorbent assay (ELISA) was used to evaluate salivary HBD-2. McNemar's Chi-square, Paired samples t-test, and one-way ANOVA were used to analyze the results. P < 0.05 was considered statistically significant. RESULTS Following the SKP intervention, the clinical parameters such as PI and GI improved significantly in all the groups (P < 0.001); however, Group III showed a significant reduction as compared to the other groups. The mean baseline salivary HBD-2 levels of Group I, Group II, and Group III were 91.78 ng/μl, 110.22 ng/μl, and 157.63 ng/μl which was further decreased to 95.22 ng/μl, 98.22 ng/μl, and 132.88 ng/μl, respectively, following SKP intervention (P < 0.001). However, Group III had a higher HBD-2 level at 90 th day as compared to other groups. CONCLUSION There was an improvement in PI and GI with a decrease in salivary HBD-2 in chronic periodontitis patients following SKP. Hence, SKP can be considered as an adjunct to treatment modality in patients with periodontal disease.

Abstract
OBJECTIVES To assess postoperative pain and pattern of recovery to normal diet in children who underwent tonsillectomy. METHODS Cold steel tonsillectomy (or adenotonsillectomy) was performed in 61 children. Haemostasis was attained with sutures in Group 1 (n = 30, 8 tonsillectomy and 22 adenotonsillectomy), and electrocautery in Group 2 (n = 31, 6 tonsillectomy and 25 adenotonsillectomy). Information obtained included postoperative pain scores and the number of postoperative days taken to resume normal diet. The pain score was evaluated with the Wong-Baker FACES® Pain Rating Scale (WBFS). RESULTS Pain values in Group 1 (haemostasis with sutures) were significantly lower than those in Group 2 (haemostasis with cauterisation) from the 6th hour to the 7th postoperative day (P < .05). For both liquid and solid food, Group 1 returned to normal diet earlier, compared to Group 2 (P < .05). When comparing patients undergoing tonsillectomy vs adenotonsillectomy, resumption of normal diet was achieved later in the adenotonsillectomy patients (P < .05). In terms of postoperative bleeding, there were 2 significant events in Group 2 (electrocautery group), occurring on the 1st (severe) and 10th day (slight) in 2 children (6.5%). There were no postoperative bleeding events in Group 1. CONCLUSION Our results showed that suture haemostatis causes less pain and faster resumption of normal diet compared to electrocautery. In view of this, we recommend the use of sutures for achieving intraoperative haemostasis in paediatric patients.

Abstract
The current standard of treating early Barrett's neoplasia is resection of visible lesions using endoscopic mucosal resection (EMR) followed by ablative therapy to the Barrett's segment. There is increasing evidence to support the use of endoscopic submucosal dissection (ESD) where en-bloc resection and lower recurrence rates may be achieved. However, ESD is associated with deep submucosal dissection when compared to EMR. This may increase the risk of complications including stricture formation with subsequent radiofrequency ablation (RFA) therapy. The aim of this study is to compare the safety and efficacy of RFA following EMR and ESD as well as when RFA was used without prior endoscopic resection. The primary outcome measure was complication rates. Clearance of dysplasia (CRD) and clearance of intestinal metaplasia (CRIM) were secondary outcomes. A retrospective analysis of a cohort of 91 patients referred for RFA from a single academic tertiary center was performed. The choice of endoscopic resection method was tailored according to the lesion type and morphology. Focal and circumferential ablation was performed after initial follow up endoscopy postresection. Patients proceeded straight to RFA in the absence of any visible lesions. In this study, the ESD group had a higher proportion of cancers compared to the EMR cohort (74.1% vs. 30.2%, P < 0.01) prior to RFA. All complications post RFA occurred in the groups with previous endoscopic resection. There was no significant difference in the total complication rate (7.4% vs. 9.3%, P = 0.78) and stricture formation rate (3.7% vs. 9.3%, P = 0.38) between the ESD and EMR groups. CRD was achieved in 96.3% in the ESD group, 88.4% in the EMR group, and all patients in the RFA alone group. CRIM rates were similar in the EMR and ESD groups (81.4% vs. 85.2%) but higher in the RFA alone group (90.5%). In conclusion, RFA following ESD is very effective and not associated with an increased risk of complications compared to EMR. This supports the application of RFA in the treatment algorithm of patients undergoing ESD for Barrett's neoplasia.

Abstract
Foot-and-mouth disease (FMD) is, arguably, the animal disease with the most devastating global economic impact owing in part, to the severe trade restrictions imposed upon affected countries and regions. South Asia is one of the regions where widespread lineages of the FMDV virus (FMDV) have emerged. Here, we performed an integrative phylogenetic analysis of all FMDV serotypes (A, O and Asia-1) circulating in southern Asia, including viral sequences collected until 2013. Our results describe the occurrence of FMD caused by different serotypes and lineages, focusing in the cycles where a specific lineage predominates within a region for a protracted period and then are rapidly or progressively replaced by an emergent or re-emergent strain that is introduced from an adjacent region. Transmission between the two main regions in southern Asia (the Indian subcontinent and the region comprised by Afghanistan, Iran and Pakistan) has been limited. Results of time divergence estimation of lineages that currently circulate in this region indicate that the most recent common ancestor of endemic lineages are: 1992 [1989-1995] for lineage O/PanAsia; 1997 [1995-1999] for PanAsia2; 2001 [1998-2004] for O/Ind2001; 2001 [2000-2002] for A/Iran-05; 1990 [1988-1991] for A/G-18 (G-VII); 2003 [2000-2006] for Asia-1 Sindh08 and 2002 [1999-2004] for Asia-1 G-VIII. We estimated the mean of the overall substitution rate of the VP1 coding region (substitution/site/year) for serotype O (5.95 × 10-3 ), serotype A (1.19 × 10-2 ) and serotype Asia-1 (3.08 × 10-3 ). The potential factors driving the lineage turnover are discussed. Our results provide insights into the ecological and evolutionary factors driving the emergence of FMDV.

Abstract
Foot-and-mouth disease (FMD) is an important transboundary disease with substantial economic impacts. Although between-herd transmission of the disease has been well studied, studies focusing on within-herd transmission using farm-level outbreak data are rare. The aim of this study was to estimate parameters associated with within-herd transmission, host physiological factors and FMD virus (FMDV) persistence using data collected from an outbreak that occurred at a large, organized dairy farm in India. Of 1,836 regularly vaccinated, adult dairy cattle, 222 had clinical signs of FMD over a 39-day period. Assuming homogenous mixing, a frequency-dependent compartmental model of disease transmission was built. The transmission coefficient and basic reproductive number were estimated to be between 16.2-18.4 and 67-88, respectively. Non-pregnant animals were more likely to manifest clinical signs of FMD as compared to pregnant cattle. Based on oropharyngeal fluid (probang) sampling and FMDV-specific RT-PCR, four of 36 longitudinally sampled animals (14%) were persistently infected carriers 10.5 months post-outbreak. There was no statistical difference between subclinical and clinically infected animals in the duration of the carrier state. However, prevalence of NSP-ELISA antibodies differed significantly between subclinical and clinically infected animals 12 months after the outbreak with 83% seroprevalence amongst clinically infected cattle compared to 69% of subclinical animals. This study further elucidates within-herd FMD transmission dynamics during the acute-phase and characterizes duration of FMDV persistence and seroprevalence of FMD under natural conditions in an endemic setting.
