Abstract
Widespread screening for hepatitis C virus (HCV) is necessary for Canada to meet its HCV elimination goals by 2030. People who currently or previously injected drugs are at high risk for HCV. Opioid agonist therapy (OAT, such as methadone and buprenorphine) has been shown to help stabilize the lives of people who are opioid-dependent. The distribution of OAT in North America typically requires daily, weekly, or monthly clinic visits and presents an opportunity for engagement, screening and treatment for those at high-risk of HCV. In this study, HCV screening was conducted by staff at OAT clinics in Ontario from 2016 to 2020 and those with chronic infections were treated on-site with direct-acting antivirals. Point-of-care or dried blood spot (DBS) testing was used for antibodies, DBS or serum for HCV RNA and serum for HCV RNA at SVR12 (sustained virological response). Clinics screened 1954 people (mean age 40 years ±12, 63% male). Forty-five percent were antibody positive, of whom 64% were HCV RNA+. Eighty percent of those RNA+ set an appointment in which 99% attended. Ninety-six percent started treatment with 87% completing treatment. Sixty-eight percent of people who completed treatment submitted a sample for SVR12 testing of which 97% achieved a virological cure. Results suggest that HCV screening and treatment at OAT clinics is feasible, effective and warrants expansion. Data suggest strong treatment adherence due to high rates of SVR12 comparable with other OAT-based HCV treatment programs. The lack of SVR12 sampling could be addressed by either on-site phlebotomy or incentivizing SVR12 sampling.

Abstract
Peptide receptor radionuclide therapy (PRRT) has become mainstream therapy of metastatic neuroendocrine tumors not controlled by somatostatin analog therapy. Currently, beta particle-emitting radiopharmaceuticals are the mainstay of PRRT. Alpha particle-emitting radiopharmaceuticals have a theoretic advantage over beta emitters in terms of improved therapeutic efficacy due to higher cancer cell death and lower nontarget tissue radiation-induced adverse events due to shorter path length of alpha particles. We discuss the available evidence for and the role of alpha particle PRRT.

Abstract
Temporomandibular joint osteoarthritis (TMJ OA) is a prevalent degenerative disease characterized by chronic pain and impaired jaw function. The complexity of TMJ OA has hindered the development of prognostic tools, posing a significant challenge in timely, patient-specific management. Addressing this gap, our research employs a comprehensive, multidimensional approach to advance TMJ OA prognostication. We conducted a prospective study with 106 subjects, 74 of whom were followed up after 2 to 3 y of conservative treatment. Central to our methodology is the development of an innovative, open-source predictive modeling framework, the Ensemble via Hierarchical Predictions through Nested cross-validation tool (EHPN). This framework synergistically integrates 18 feature selection, statistical, and machine learning methods to yield an accuracy of 0.87, with an area under the ROC curve of 0.72 and an F1 score of 0.82. Our study, beyond technical advancements, emphasizes the global impact of TMJ OA, recognizing its unique demographic occurrence. We highlight key factors influencing TMJ OA progression. Using SHAP analysis, we identified personalized prognostic predictors: lower values of headache, lower back pain, restless sleep, condyle high gray level-GL-run emphasis, articular fossa GL nonuniformity, and long-run low GL emphasis; and higher values of superior joint space, mouth opening, saliva Vascular-endothelium-growth-factor, Matrix-metalloproteinase-7, serum Epithelial-neutrophil-activating-peptide, and age indicate recovery likelihood. Our multidimensional and multimodal EHPN tool enhances clinicians' decision-making, offering a transformative translational infrastructure. The EHPN model stands as a significant contribution to precision medicine, offering a paradigm shift in the management of temporomandibular disorders and potentially influencing broader applications in personalized healthcare.

Abstract
OBJECTIVE We assessed the accuracy of two portable ultrasound machines (PUM) in obtaining fetal biometry and estimating gestational age. METHODS We analyzed data from the Fetal Age Machine Learning Initiative, an observational study of pregnant women in the United States and Zambia. Each participant underwent assessment by an experienced sonographer using both a high-specification ultrasound machine (HSUM) and a PUM (either Butterfly iQ or Clarius C3) to measure fetal biometry and calculate estimated gestational age (EGA) at each visit. Through comparison of paired PUM-HSUM scans, we estimated agreement between individual biometry measurements and aggregate gestational age estimates by reporting mean difference, along with intraclass correlation coefficient (ICC) and Bland-Altman plots, adjusting for trend. RESULTS 881 participants contributed 1386 paired PUM-HSUM ultrasound studies between April and December 2021. PUM studies included 991 Butterfly and 395 Clarius. Gestational age at scan ranged from 7 to 38 weeks. Compared to HSUM, the Butterfly PUM had a mean difference of -0.20 days (95%CI±0.40) in the 1st trimester and -0.68 days (95%CI±0.68) in the 2nd/3rd trimesters. Also compared to HSUM, the Clarius PUM had a mean difference of 0.47 days (95%CI±0.64) in the 1st trimester and -1.67 days (95%CI±0.43) in the 2nd/3rd trimesters. ICCs were 0.989 or greater throughout. Increasing gestational age was associated with increasing error and absolute error. Both PUM devices demonstrated a modest trend toward underestimation of EGA at advancing gestational ages in 2nd/3rd trimester scans, compared to HSUM. CONCLUSION Both the Butterfly iQ and Clarius C3 PUM devices were highly accurate in performing fetal biometry in a diverse population from the US and Zambia. This article is protected by copyright.

Abstract
BACKGROUND Idiopathic scleroma (previously coined solitary idiopathic choroiditis or focal scleral nodule) is an innocuous lesion affecting the sclera with intraocular manifestations. It is often the basis of many misdiagnoses such as amelanotic choroidal melanoma, osteoma or metastatic lesions. Patients are often asymptomatic and the course is benign. With increasing use of community based imaging, more of such cases are being identified. This paper is a retrospective case series investigating the multi-modal imaging findings of idiopathic scleroma. METHODS A retrospective analysis of prospectively collected data were analysed. Over the course of January 2008-January 2022, 44 patients diagnosed with idiopathic scleroma and imaged with wide-field colour fundus photography, fundus autofluorescence, ocular coherence tomography (OCT) and B-scan ultrasonography. Due to a poor image, only 43 images were included for OCT review. We also reviewed our patient's demographics, symptoms and baseline ophthalmic characteristics upon presentation. RESULTS The mean age was 52 years (range 32-79) and there was no predilection towards gender. All lesions were post equatorial with the most common location being inferotemporal (n = 16, 36%); 32 lesions (73%) were yellow on fundus photography. 82% (n = 36/44) of lesions exhibited hyperautoflourescence and 43 lesions (98%) showed hyperechogenicity on B-scan ultrasonography. 100% of lesions originated from the sclera with no lesions showing active inflammation. 20 (47%) lesions had associated blood vessels overlying them on OCT. DISCUSSION Idiopathic scleroma is a yellow, hyperautofluorescent, hyperechogeneic scleral lesion that has no signs of active inflammation. These characteristics help define them from other more sinister cause of amelanotic fundal lesions.

Abstract
Objective: The objective of this study is to evaluate the awareness of cross-infection control measures followed by DHCPs during the 5th wave of Covid-19 pandemic, Omicron variant in a government sector university of Karachi, Pakistan. Method: A Cross-sectional study was conducted from June till September 2022 at Sindh Institute of Oral Health Science during the 5th wave of Covid 19 pandemic, Omicron variant. Data was collected from 153 DHCPs from government sector university using a self-administered questionnaire, comprising of 20 closed ended question to assess the awareness and practice of cross infection protocols by DHCPs. Results: 98.7% of the participants were vaccinated against Covid 19. 96% of the participants used surgical gowns, face shields, and face masks as part of PPE during examining patients and while performing procedure. After treatment 99.3% of participants washed hands with hand wash, soap or used antiseptic solution. 77.1% of participants asked for Covid 19 test report and 68.6% of participants asked for proof of vaccination against covid 19 before treating patients. 96.1% of participants recommended disinfection of dental unit after every patient. 98% of participants changed glove after every patient. 88.2% of the participants said they would carry all elective and emergency procedures. Conclusion: The results of this study show that DHCPs practicing at government sector university have adequate knowledge regarding prevention of cross infection protocols and their importance to limit spread of infections. But their practice of prevention of cross infection during Covid 19 pandemic is not ideal as percentage of DHCPs requiring proof of vaccination or negative reports for Covid 19 were rather low and the percentage of DHCPs willing to carry elective procedures along with emergency ones was rather high.

Abstract
BACKGROUND/AIMS Gastric emptying scintigraphy is commonly performed to assess for dysmotility. A standardized meal with associated threshold criteria was established in 2000 to enable robust interpretation. However, no guidance is available to interpret results when patients do not ingest the entire meal. The purpose of this study is to determine the continued appropriateness of the threshold criteria in contemporary clinical practice and its relevance for partially ingested meals. METHODS This retrospective study analyzed patients (n = 1365 total) who underwent solid-phase gastric emptying scintigraphy at an academic medical center. Patients were stratified based on their completion of the standard meal. Patients were further stratified into normal and delayed gastric emptying cohorts based on the current criteria. Percent gastric retention values at 1, 2, 3, and 4 h were compared. RESULTS Median (95% upper reference) normal gastric retention values for the complete standard meal were 64% (87%) at 1 h, 25% (60%) at 2 h, 13% (54%) at 3 h and 4% (9%) at 4 h. Consumption of at least 50% of the standard meal yielded similar retention; 53% (86%) at 1 h, 19% (58%) at 2 h, 6% (29%) at 3 h and 3% (10%) at 4 h. There was no significant age- or gender-specific differences using the current criteria, and no differences were observed based on diabetic status. Retention values matched well with the current criteria and validated with data-driven clustering. CONCLUSION Adult normative standards for gastric emptying scintigraphy are appropriate for differentiating normal and delayed populations and can be applied to partial meals with at least 50% completion.

Abstract
Introduction Schools remain at the frontlines of addressing issues, such as e-cigarette use, that impact students. Despite e-cigarette use remaining a significant public health concern in the U.S., schools have limited resources (e.g., staff, capacity, programming) to address it, especially in rural and frontier areas. This ECHO Pilot Project aimed to build capacity and equip schools and school staff in the state of Kansas to address high rates of youth e-cigarette use by providing prevention support and information on best practices for e-cigarette cessation. Methods and analysis The pilot used the established Project ECHO model to disseminate evidence-based strategies for e-cigarette prevention and cessation among youth to schools across Kansas. The pilot selected 20 interdisciplinary school teams representing both rural and urban middle and high schools across the state to participate in seven ECHO sessions. ECHO sessions proceeded throughout Fall 2021, with the final session in Spring 2022. School participants completed pre-post surveys as well as component-specific surveys following each ECHO session. In addition, each school team created an individualized action plan to comprehensively address e-cigarette use at their school based on the information provided throughout the ECHO. Survey data, school tobacco/nicotine policies, and action plans will be analyzed to assess process and final outcomes. Discussion If successful, this pilot will demonstrate that the ECHO model is an effective platform for building school staff knowledge and skills to implement evidence-based strategies in both urban and rural settings. It is anticipated that the pilot will build capacity and equip schools and school staff to address high rates of youth e-cigarette use by providing support for school-based prevention programs and referrals for e-cigarette cessation which will lessen the burden of nicotine-related problems in Kansas schools and communities. Finally, the pilot will provide evidence that the ECHO model can be successfully and equitably applied in a school setting and may be a viable method for addressing other public health-related issues faced by schools.

Abstract
Objectives: To assess the gap between knowledge of interdental cleaning aids and the usage of dental floss among dental students.
Materials and Methods: A cross-sectional study was undertaken at the Jinnah Sindh Medical University, Sindh Institute of Oral Health Sciences, Karachi, Pakistan, between March to May 2022. Using select statistics electronic software, a sample size of 172 was estimated, however, we included 200 participants in the study considering an expected drop-out rate of 15%. A structured questionnaire was designed to collect data from undergraduate dental students. All data were entered and analyzed using SPSS version 26. Percentages and frequencies were calculated to assess the knowledge and implementation of that knowledge among undergraduate dental students. In Association between the year of study and the use of dental floss, a chi-square test was used. A p-value of < 0.05 was set as the cut-off for statistical significance.
Results: A total of 200 participants were included with 24.5%males and 75.5%females. There was a significant association of interdental cleaning aid awareness with gender (p=0.007). Only a small percentage of females knew that waterjets and rubber tips were interdental cleaning aids while the majority of the respondents irrespective of gender knew that dental floss is interdental cleaning aid. Dental floss usage was significantly higher in the female population than in males (18.37% vs. 50.33%; p=0.019).
Conclusion: Our study concluded that while the majority of dental students had knowledge that dental floss should be a routine habit, they themselves were not practicing it. Moreover, about 30% of the study population claimed that they only brushed once a day only. The use of dental floss was significantly more frequent in female dental students.

Abstract
INTRODUCTION 177Lu-vipivotide tetraxetan is a radiopharmaceutical that selectively targets prostate-specific membrane antigen (PSMA) and delivers beta-radiations to kill prostate cancer cells. AREAS COVERED Extensive experience outside the United States as well as randomized phase II and phase III data demonstrate that 177Lu-vipivotide tetraxetan is a safe, generally well tolerated, and effective therapy for men with mCRPC. 177Lu-vipivotide tetraxetan was approved by the FDA in March 2022 for the treatment of PSMA-positive metastatic castration-resistant prostate cancer (mCRPC) after androgen receptor pathway inhibition and taxane-based chemotherapy based on the results of the VISION trial. EXPERT OPINION This review discusses the development and studies leading to the approval of 177Lu-vipivotide tetraxetan. In all, 177Lu-vipivotide tetraxetan is an exciting new tool in the arsenal for men with mCRPC after novel androgen pathway inhibitors and at least one taxane chemotherapy. Optimal selection of patients, sequencing of 177Lu-vipivotide tetraxetan with the other agents available to treat mCRPC, and the use of dosimetry are current areas of interest with great potential and opportunities for further individual patient optimization using the tools of theranostics.

Abstract
The APOBEC3 family of cytosine deaminases has been implicated in some of the most prevalent mutational signatures in cancer1-3. However, a causal link between endogenous APOBEC3 enzymes and mutational signatures in human cancer genomes has not been established, leaving the mechanisms of APOBEC3 mutagenesis poorly understood. Here, to investigate the mechanisms of APOBEC3 mutagenesis, we deleted implicated genes from human cancer cell lines that naturally generate APOBEC3-associated mutational signatures over time4. Analysis of non-clustered and clustered signatures across whole-genome sequences from 251 breast, bladder and lymphoma cancer cell line clones revealed that APOBEC3A deletion diminished APOBEC3-associated mutational signatures. Deletion of both APOBEC3A and APOBEC3B further decreased APOBEC3 mutation burdens, without eliminating them. Deletion of APOBEC3B increased APOBEC3A protein levels, activity and APOBEC3A-mediated mutagenesis in some cell lines. The uracil glycosylase UNG was required for APOBEC3-mediated transversions, whereas the loss of the translesion polymerase REV1 decreased overall mutation burdens. Together, these data represent direct evidence that endogenous APOBEC3 deaminases generate prevalent mutational signatures in human cancer cells. Our results identify APOBEC3A as the main driver of these mutations, indicate that APOBEC3B can restrain APOBEC3A-dependent mutagenesis while contributing its own smaller mutation burdens and dissect mechanisms that translate APOBEC3 activities into distinct mutational signatures.

Abstract
IMPORTANCE Neoadjuvant immunotherapy is a novel approach with the potential to improve outcomes for patients with oral cavity squamous cell cancer (OCSCC). Adverse events of varying severity are reported with immunotherapy, and a biomarker to predict response would be clinically useful to avoid toxic effects in those unlikely to benefit. OBJECTIVE To correlate changes on fluoro-[18F]-deoxy-2-D-glucose positron emission tomography/computed tomography (FDG-PET/CT) scans with primary tumor pathologic response and immunologic biomarkers in patients with OCSCC receiving neoadjuvant immunotherapy. DESIGN, SETTING, AND PARTICIPANTS This was a retrospective analysis of serial FDG-PET/CT scans obtained prospectively as part of a phase 2 open-label randomized clinical trial investigating neoadjuvant immunotherapy in patients with untreated OCSCC between 2016 and 2019. Included were a total of 29 patients from a single academic medical center with untreated OCSCC (≥T2, or clinically node positive) randomized 1:1 to receive neoadjuvant therapy with single agent nivolumab or combination nivolumab and ipilimumab followed by surgery and standard of care adjuvant therapy. INTERVENTIONS The interventions in this study were FDG-PET/CT scans before (T0) and after (T1) preoperative immunotherapy. MAIN OUTCOMES AND MEASURES Data collected from FDG-PET/CT scans included maximum standardized uptake value (SUVmax) of primary OCSCC and cervical lymph nodes (LNs) at T0 and T1 and new LN uptake and uptake consistent with radiologic immune-related adverse events (irAEs) at T1. Primary OCSCC pathologic response reported as percentages of viable vs nonviable tumor. The number of CD8+ cells/mm2 was determined in the primary tumor biopsy specimen and at surgery. RESULTS There was no correlation between pathologic response and change in SUVmax in the primary OCSCC between T0 and T1. Out of 27 total participants, 13 had newly FDG-avid ipsilateral LNs at T1, most negative on pathology. A total of 9 had radiologic irAEs, most commonly sarcoid-like LN (7 of 27). No correlations were found between primary OCSCC SUVmax at T0 and CD8+ T-cell number in the primary tumor biopsy, and no correlations were found between primary OCSCC SUVmax at T1 and CD8+ T-cell number in the primary tumor at surgery. CONCLUSIONS AND RELEVANCE There were no correlations between changes in FDG uptake after neoadjuvant immunotherapy and pathologic primary tumor response. Importantly, newly FDG-avid ipsilateral LNs following neoadjuvant immunotherapy were commonly observed but did not represent progressive disease or indicate pathologically disease positive nodes in most cases. These findings argue against altering surgical plans in this setting and suggest that the role of FDG-PET/CT may be limited as an early imaging biomarker for predicting pathologic response to preoperative immunotherapy for OCSCC.

Abstract
The aim of the present research work is to design miconazole-loaded chitosan nanoparticles that could potentially assemble in wrinkle and hair follicles to provide prolong release to the skin tissue. The amount of drugs required for the preparation of nanoparticles was determined by studying the entrapment efficiency of preliminary batches. The emulsification/Solvent evaporation method was used for the preparation of nanoparticles. Different proportions of Miconazole Nitrate and Chitosan were dissolved in DCM. The size of the globules in the emulsion was reduced by a high energy shearing using a probe Sonicator at 50 % amplitude for 10 Minutes, followed by the addition of 10 ml 2% PVA. After overnight evaporation of DCM, for isolation of dried NPs, the NPs dispersion was centrifuged at 15,000 RCF for 30 minutes. The obtained particles were dispersed in de-ionized water and freeze-dried. 32 full factorial design was selected for optimization purposes. Prepared batches were evaluated for various parameters such as entrapment efficiency, production yield, particle size, zeta potential, and SEM. F5 batch was found to be optimized which was then used for the preparation of gel. Three levels of Carbopol934 and propylene glycol were used for the optimization of gel. The prepared gel was also evaluated for pH, drug content, viscosity, and spreadability. From the study, it was concluded that nanoparticle gel can be used for the treatment of various skin infections over the conventional gel.

Abstract
The objective of the current work is to formulate and evaluate the mouth dissolving film of domperidone. It is ideally suitable for the treatment of emesis. The mouth dissolving film of domperidone is useful in the vomiting through the journey. Mouth dissolving films were formulated by the solvent casting technique and its in-vitro as well as the in-vivo evaluation was done by the usual pharmacopoeial and unofficial tests and by using human volunteers. The main benefit of the preparation technique includes fewer operation units, better content consistency. The mouth dissolving film formed was found to be disintegrated in 1 minute. The ratio of components in the aqueous phase affected the thickness, drug content, tensile strength, percentage elongation, folding endurance, and release profile of mouth dissolving film and the best results were obtained for the HPMC E15 and polyethyleneglycol. The compatibility between domperidone and excipients was confirmed by FTIR and DSC studies. The developed mouth dissolving film of domperidone demonstrated usefulness for fast release of drug in mouth, for better drug utilization, and improved patient compliance. The optimized formulation, due to low HPMC E15 content, has optimum tensile strength and thickness. Formulation F8 containing HPMC E15 and PG showed a cumulative % drug release of 95.10 at the end of 12 minutes. HPMC E15 films showed higher cumulative % drug release than films of other HPMC E grades at different concentrations. It was found to be stable during the accelerated stability study. The effect of different concentrations of polymers and plasticizers on in-vitro evaluation parameters was evaluated. Hence, data showed that formulation F8 was the most suitable for the development of fast dissolving oral films of domperidone.

Abstract
Neuroendocrine neoplasms are known to have heterogeneous biological behavior. G3 neuroendocrine tumours (NET G3) are characterized by well-differentiated morphology and Ki67 > 20%. The prognosis of this disease is understood to be intermediate between NET G2 and neuroendocrine carcinoma (NEC). Clinical management of NET G3 is challenging due to limited data to inform treatment strategies. We describe clinical characteristics, treatment, and outcomes in a large single centre cohort of patients with gastroenteropancreatic NET G3. Data was reviewed from 26 cases managed at Queen Elizabeth Hospital, Birmingham, UK, from 2012 to 2019. Most commonly the site of the primary tumour was unknown and majority of cases with identifiable primaries originated in the GI tract. Majority of cases demonstrated somatostatin receptor avidity. Median Ki67 was 30%, and most cases had stage IV disease at diagnosis. Treatment options included surgery, somatostatin analogs (SSA), and chemotherapy with either platinum-based or temozolomide-based regimens. Estimated progression free survival was 4 months following initiation of SSA and 3 months following initiation of chemotherapy. Disease control was observed following treatment in 5/11 patients treated with chemotherapy. Estimated median survival was 19 months; estimated 1 year survival was 60% and estimated 2 year survival was 13%. NET G3 is a heterogeneous group of tumours and patients which commonly have advanced disease at presentation. Prognosis is typically poor, though select cases may respond to treatment with SSA and/or chemotherapy. Further study is needed to compare efficacy of different treatment strategies for this disease.

Abstract
Osteoarthritis is a chronic disease that affects the temporomandibular joint (TMJ), causing chronic pain and disability. To diagnose patients suffering from this disease before advanced degradation of the bone, we developed a diagnostic tool called TMJOAI. This machine learning based algorithm is capable of classifying the health status TMJ in of patients using 52 clinical, biological and jaw condyle radiomic markers. The TMJOAI includes three parts. the feature preparation, selection and model evaluation. Feature generation includes the choice of radiomic features (condylar trabecular bone or mandibular fossa), the histogram matching of the images prior to the extraction of the radiomic markers, the generation of feature pairwise interaction, etc.; the feature selection are based on the p-values or AUCs of single features using the training data; the model evaluation compares multiple machine learning algorithms (e.g. regression-based, tree-based and boosting algorithms) from 10 times 5-fold cross validation. The best performance was achieved with averaging the predictions of XGBoost and LightGBM models; and the inclusion of 32 additional markers from the mandibular fossa of the joint improved the AUC prediction performance from 0.83 to 0.88. After cross-validation and testing, the tools presented here have been deployed on an open-source, web-based system, making it accessible to clinicians. TMJOAI allows users to add data and automatically train and update the machine learning models, and therefore improve their performance.

Abstract
AbstractObjectives : The brain damage associated with schizophrenia has been established beyond doubt; however, what remains unexplored is the biological nature of transcultural variations. An important reason for this was the lack of mid and high field scanners in developing countries like India.
Material and Methods : We undertook a pilot study using a 0.5 Tesla MRI scanner (General Electric Signa Contour) to explore identifiable structural brain lesions in ten randomly selected individuals with schizophrenia.
Results: Nine of the ten participants in the series had structural brain changes. The most common findings were ventricular dilatation and prominent cerebral cortical sulci and cerebellar folia. Additionally non-focal white matter lesions were observed in three patients and small right hippocampus was noted in one participant.
Conclusions : The study discusses that establishing structural brain lesions with mid field scanners is indeed feasible. The small study sample and heterogeneity of schizophrenia however made it difficult to establish any definite associations

Abstract
Abstract
Background
TEPs ensure every patient has a ceiling of care formally documented, including a DNACPR decision. This pre-empts complications and provides guidance on how to appropriately manage acutely unwell patients. There is no national standard for TEPs. Our aim: to formally document the incidence of TEP completion in general surgery at a local District General Hospital.
Method
A multi-phase, cross-sectional study of 1. Inpatients on three general surgical wards, 2. TEP completion at post-take after a typical on-call cycle.
Results
15.4% of TEPs were completed, of which 75% had a DNARCPR form. For the two post-take ward rounds, 5% and 7.7% of admitted patients had a TEP. Elective surgical/Enhanced recovery patients (ERP) did not have a TEP. Findings were presented locally, and posters placed in the surgical offices. Cycle 2: 19.6% and 10% completion rate for ward and post-take patients, respectively.
Conclusions
TEPs are rarely completed. Minimal improvement in completion rate was noted at cycle 2. TEPs are more commonly completed for patients not for resuscitation. Future aims include editing the surgical clerking proforma and the elective surgery/ERP paperwork to encourage completion, improving patient care. Currently we are arranging similar audits across other NHS trusts to determine if this is a national problem.

Abstract
Abstract
Funding Acknowledgements
Type of funding sources: None.
Background
Pulmonary vein (PV) anatomy and sizing is important to know before performing PV isolation. This information is conventionally obtained by angiography or by CT scan.
Aim
We undertook this study to identify and measure the PVs during TEE studies and validate these against angiography.
Method
17 consecutive patients due to undergo PV isolation for paroxysmal atrial fibrillation were analysed. Using TEE, the PVs were visualised (Upper panel) as follows: i) From the mid-esophageal four chamber view, the chamber probe was turned to the right at 110-130º for the bicaval view, where the RSPV was seen entering the left atrium adjacent to the SVC. ii) At 0º the SVC was imaged in its short axis, and the probe advanced till the interatrial septum was seen. The angle was changed to 30º to visualise the right inferior PV (RIPV). iii) From the two chamber view (70-90º), the probe was turned to the left and withdrawn to display the left superior PV (LSPV) entering the left atrium parallel to the appendage.iv) Keeping the LSPV in focus, the angle was changed to 135º and the probe advanced till the AV groove, where the left inferior PV (LIPV) was visualised. After transseptal puncture, each PV was cannulated. The PV angiograms were performed in several projections to obtain the best PV profile (lower panel). Using electronic callipers, each PV was measured within 1 cm of its entry into the left atrium, after having received all tributaries. Those PVs were considered for analysis which were measured by both TEE and angiography. The paired ‘T’ test was used to compare the PV diameters by TEE and angiography and the Bland Altman analysis was done to see the level of agreement.
Results
Of a total of 68 PVs, 62 could be adequately visualised by TEE and 50 by angiography. These 50 PVs were measured using both methods. The diameters of the PVs measured by TEE and angiography were not statistically different by the paired t test; LSPV14 ± 1.8 mm v/s 14.4 ± 2.1 mm; RSPV 13 ± 1.8 mm v/s 14.6 ± 3.5 mm; LIPV 11.9 ± 2.1 vs 13.2 ± 2.8 mm and RIPV 10.5 ± 2.7 vs 12.1 ± 2.9 mm. Bland Altman analysis showed most PV sizes estimated by TEE and angiography lay within limits of agreement.
Conclusions
A majority of PVs can be visualised by TEE using a defined protocol. TEE is a good technique to visualise and assess the size of PVs, avoiding the need for contrast medium and radiation.

Abstract
Accurate assessment of fetal gestational age (GA) is critical to the clinical management of pregnancy. Industrialized countries rely upon obstetric ultrasound (US) to make this estimate. In low- and middle- income countries, automatic measurement of fetal structures using a low-cost obstetric US may assist in establishing GA without the need for skilled sonographers. In this report, we leverage a large database of obstetric US images acquired, stored and annotated by expert sonographers to train algorithms to classify, segment, and measure several fetal structures: biparietal diameter (BPD), head circumference (HC), crown rump length (CRL), abdominal circumference (AC), and femur length (FL). We present a technique for generating raw images suitable for model training by removing caliper and text annotation and describe a fully automated pipeline for image classification, segmentation, and structure measurement to estimate the GA. The resulting framework achieves an average accuracy of 93% in classification tasks, a mean Intersection over Union accuracy of 0.91 during segmentation tasks, and a mean measurement error of 1.89 centimeters, finally leading to a 1.4 day mean average error in the predicted GA compared to expert sonographer GA estimate using the Hadlock equation.

Abstract
We used social network analysis (SNA) to study the novel coronavirus (COVID-19) outbreak in Karnataka, India, and to assess the potential of SNA as a tool for outbreak monitoring and control. We analysed contact tracing data of 1147 COVID-19 positive cases (mean age 34.91 years, 61.99% aged 11-40, 742 males), anonymised and made public by the Karnataka government. Software tools, Cytoscape and Gephi, were used to create SNA graphics and determine network attributes of nodes (cases) and edges (directed links from source to target patients). Outdegree was 1-47 for 199 (17.35%) nodes, and betweenness, 0.5-87 for 89 (7.76%) nodes. Men had higher mean outdegree and women, higher mean betweenness. Delhi was the exogenous source of 17.44% cases. Bangalore city had the highest caseload in the state (229, 20%), but comparatively low cluster formation. Thirty-four (2.96%) 'super-spreaders' (outdegree ⩾ 5) caused 60% of the transmissions. Real-time social network visualisation can allow healthcare administrators to flag evolving hotspots and pinpoint key actors in transmission. Prioritising these areas and individuals for rigorous containment could help minimise resource outlay and potentially achieve a significant reduction in COVID-19 transmission.

Abstract
The optimum imaging modality for the screening of multiple endocrine neoplasia type 1 (MEN1)-associated tumors is not well established. Here, we compare the performance of contrast-enhanced CT (CECT) versus 68Ga DOTA-NOC/TATE PET/CT in MEN1 patients. The retrospective case record study is conducted at a tertiary health-care center. Thirty-four patients, who have undergone both CECT and 68Ga DOTA-NOC/ TATE PET, were included in the analysis. CECT had higher per-lesion sensitivity than 68Ga DOTA-NOC/TATE PET/CT for the detection of parathyroid lesions, (82.6% vs. 24.6%, P < 0.001). 68Ga DOTA-NOC/TATE PET/CT had higher per-lesion sensitivity than CECT for the detection of metastases (85% vs. 47.5%, P < 0.001) and gastrinomas (90% vs. 10%, P = 0.003). When combined use of the two imaging modalities is compared to CECT alone (63.7% vs. 93.1%, P = 0.00012) and 68Ga-DOTA-NOC/TATE PET/CT alone (74.1% vs. 93.1%, P = 0.0057), it provided significantly higher per-lesion sensitivity for the detection of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). 68Ga-DOTA-NOC/ TATE PET was more sensitive for the detection of gastrinomas and metastases than CECT, whereas it was less sensitive for the detection of parathyroid lesions than CECT. The combined use of both the imaging modalities significantly increases the sensitivity for detection of GEP-NETs.

Abstract
Abstract
Introduction and case report description
A 54-year-old male with no past cardiac disease was experiencing a productive cough, fevers, chills, and shortness of breath for 3 days in the community. His dyspnea worsened significantly, and he then presented to the emergency room. He admitted to using intravenous recreational drugs. His initial vital signs included a temperature of 38.2 degrees Celsius, a heart rate of 116 beats per minute, and a blood pressure of 88/42 mmHg. He had a positive pulses paradoxus with a decrease in systolic blood pressure of 14 mmHg on inspiration.
Description of the problem and procedures
This presentation was consistent with cardiac tamponade. He had an emergent echocardiogram showing a large pericardial effusion in the apical-four-chamber view (Image 1, A), including collapse of the right ventricle during diastole (Image 1, B, Green Arrow). There were also fibrin strands seen in a modified parasternal long axis view (Image 1, C, Blue Arrow). He had an emergency pericardiocentesis using real-time ultrasound guidance, which drained 400 mL of thick brown purulent fluid. A pigtail catheter was inserted to allow for continued drainage. Immediately afterwards, the patient’s blood pressure normalized, and his shortness of breath improved significantly.
Using the ultrasound, the physician also saw bilateral pleural effusions. The larger left pleural effusion was drained, and a pigtail catheter was inserted into the left pleural space. After confirming that there was no post-procedure left pneumothorax, the right pleural effusion was also drained.
An echocardiogram after the pericardiocentesis showed a significant decrease in the size of the pericardial effusion (Image 1, D).
The patient was started on broad-spectrum antibiotics, which was then narrowed after cultures from both the pericardial fluid and pleural fluid grew methicillin-susceptible Staphylococcus aureus.
Discussion
Cardiac tamponade results in increased compression of the cardiac chambers due to raised pericardial pressures. As it progresses, it can result in significant impairment in venous return, cardiac output, and blood pressure. This is a life-threatening condition if it is not promptly treated. In this case, the patient had a methicillin-susceptible Staphylococcus aureus empyema which spread contiguously into the pericardium and resulted in cardiac tamponade.
Conclusions and implications for clinical practice
This case highlights the clinical benefits of being proficient in performing a point-of-care ultrasound because a bedside echocardiogram by the physician immediately confirmed the diagnosis and allowed for safer drainage of the pericardial effusion using ultrasound guidance to decrease the chance of causing a perforation of the ventricle. Using ultrasound, the clinician was also able to promptly diagnose the pleural effusions and urgently drain them, which was necessary for achieving source control in order to fully treat the infection.

Abstract
We aimed to review the contributions by Indian researchers to the subspecialty of skeletal dysplasias (SDs). Literature search using specific keywords in PubMed was performed to retrieve all the published literature on SDs as on July 6, 2017. All published literature on SDs wherein at least one author was from an Indian institute was included. Publications were grouped into different categories based on the major emphasis of the research paper. Five hundred and forty publications in English language were retrieved and categorized into five different groups. The publications were categorized as reports based on: (i) phenotypes (n = 437), (ii) mutations (n = 51), (iii) novel genes (n = 9), (iv) therapeutic interventions (n = 31), and (v) reviews (n = 12). Most of the publications were single-patient case reports describing the clinical and radiological features of the patients affected with SDs (n = 352). We enlisted all the significant Indian contributions. We have also highlighted the reports in which Indians have contributed to discovery of new genes and phenotypes. This review highlights the substantial Indian contributions to SD research, which is poised to reach even greater heights given the size and structure of our population, technological advances, and expanding national and international collaborations.
