Abstract: The popularity of egocentric cameras and their always-on nature has lead to the abundance of day long first-person videos. The highly redundant nature of these videos and extreme camera-shakes make them difficult to watch from beginning to end. These videos require efficient summarization tools for consumption. However, traditional summarization techniques developed for static surveillance videos or highly curated sports videos and movies are either not suitable or simply do not scale for such hours long videos in the wild. On the other hand, specialized summarization techniques developed for egocentric videos limit their focus to important objects and people. This paper presents a novel unsupervised reinforcement learning framework to summarize egocentric videos both in terms of length and the content. The proposed framework facilitates incorporating various prior preferences such as faces, places, or scene diversity and interactive user choice in terms of including or excluding the particular type of content. This approach can also be adapted to generate summaries of various lengths, making it possible to view even 1-minute summaries of one's entire day. When using the facial saliency-based reward, we show that our approach generates summaries focusing on social interactions, similar to the current state-of-the-art (SOTA). The quantitative comparisons on the benchmark Disney dataset show that our method achieves significant improvement in Relaxed F-Score (RFS) (29.60 compared to 19.21 from SOTA), BLEU score (0.68 compared to 0.67 from SOTA), Average Human Ranking (AHR), and unique events covered. Finally, we show that our technique can be applied to summarize traditional, short, hand-held videos as well, where we improve the SOTA F-score on benchmark SumMe and TVSum datasets from 41.4 to 46.40 and 57.6 to 58.3 respectively. We also provide a Pytorch implementation and a web demo at https://pravin74.github.io/Int-sum/index.html.

Abstract: Nanotechnology is the science of manipulating the structural entities at nanoscale and beauty based solution industry is one of the most passionate explorer of nanostructures which contemplated as a huge boon in the cosmeceuticals for various beauty solutions. Exploration of nanostructures is escalating in the cosmeceuticals due to limitations coupled with the conventional products. Although, cosmeceutical is not FDA approved terminology but designate the personal care products at the borderline between cosmetics and pharmaceuticals. Emerging trends in cosmetics frequently include nano-sized structure novel carriers (like nano-emulsions, nanocapsules, nanosomes, niosomes or liposomes) consisting of traditional cosmetic materials. Nanocosmeceuticals contains naturally derived ingredients and synthetics too, but all contains functional ingredients with their therapeutic, disesase-flighting and healing properties. Nanocosmeceuticals has been developing with significant pace over recent years, extensively used to address beauty solutions. Nanocarriers are novel nanostructure having the advantages of effective penetration in skin, controlled site specific targeting, higherstability and entrapment efficiency. The current review put light on various aspects of nanostructure candidates in cosmetics including its synthesis, nanocarriers, regulations potentialconcerns and future trends.

Abstract: We introduce NeuroConstruct, a novel end-to-end application for the segmentation, registration, and visualization of brain volumes imaged using wide-field microscopy. NeuroConstruct offers a Segmentation Toolbox with various annotation helper functions that aid experts to effectively and precisely annotate micrometer resolution neurites. It also offers an automatic neurites segmentation using convolutional neuronal networks (CNN) trained by the Toolbox annotations and somas segmentation using thresholding. To visualize neurites in a given volume, NeuroConstruct offers a hybrid rendering by combining iso-surface rendering of high-confidence classified neurites, along with real-time rendering of raw volume using a 2D transfer function for voxel classification score versus voxel intensity value. For a complete reconstruction of the 3D neurites, we introduce a Registration Toolbox that provides automatic coarse-to-fine alignment of serially sectioned samples. The quantitative and qualitative analysis show that NeuroConstruct outperforms the state-of-the-art in all design aspects. NeuroConstruct was developed as a collaboration between computer scientists and neuroscientists, with an application to the study of cholinergic neurons, which are severely affected in Alzheimer's disease.

Abstract: Evidence for the utility of medications in settings lacking randomized trial data can come from studies of treatment persistence. The present study was undertaken to examine patterns of medication use in systemic lupus erythematosus (SLE) using data from a large multicenter longitudinal cohort.Prospectively collected data from the Asia Pacific Lupus Collaboration cohort including disease activity (SLE Disease Activity Index 2000 [SLEDAI-2K]) and medication details, captured at every visit from 2013-2018, were used. Medications were categorized as glucocorticoids (GCs), antimalarials (AM), and immunosuppressants (IS). Cox regression analyses were performed to determine the time-to-discontinuation of medications, stratified by SLE disease activity.Data from 19,804 visits of 2,860 patients were analyzed. Eight medication categories were observed: no treatment; GC, AM, or IS only; GC plus AM; GC plus IS; AM plus IS; and GC plus AM plus IS (triple therapy). Triple therapy was the most frequent pattern (31.4% of visits); single agents were used in 21% of visits, and biologics in only 3%. Time-to-discontinuation analysis indicated that medication persistence varied widely, with the highest treatment persistence for AM and lowest for IS. Patients with a time-adjusted mean SLEDAI-2K score of ≥10 had lower discontinuation of GCs and higher discontinuation of IS.Most patients received combination treatment. GC persistence was high, while IS persistence was low. Patients with high disease activity received more medication combinations but had reduced IS persistence, consistent with limited utility. These data confirm unmet need for improved SLE treatments.

Abstract: Background This study compares outcomes of patients with severe, multiplanar, fixed, pantalar deformities undergoing limb preservation with either pantalar fusion (PTF) or talectomy and tibiocalcaneal fusion (TCF), versus below knee amputation (BKA). Methods Fifty-one patients undergoing either PTF, TCF and BKA for failed management of severe pantalar deformity were evaluated retrospectively. Twenty-seven patients underwent PTF, 8 TCF and 16 BKA. Median age at surgery was 55.0 years (17–72 years) and median follow-up duration was 49.9 months (24.0–253.7 months). Clinical evaluation was undertaken using the MOxFQ, EQ-5D and Special Interest Group in Amputee Medicine score (SIGAM). Patients were also asked whether they were satisfied with their surgery and whether they would have the same surgery again. Results There was no statistically significant difference in functional outcomes, satisfaction, or complications between the groups. Twenty-two patients undergoing PTF (81.5%), 6 patients undergoing TCF (75%), and 15 patients undergoing BKA (93.8%) were satisfied overall (p = 0.414). There was no difference in the proportion of patients who would opt for the same procedure again (p = 0.142): 23 in the PTF group (85.2%), 8 in the TCF group (100%), and 11 in the BKA group (68.8%). Seven patients undergoing PTF (25.9%), 2 patients undergoing TCF (25%) and 6 patients undergoing BKA (37.5%) had major complications (p = 0.692). Conclusion This study concludes that PTF, TCF and BKA can all provide an acceptable outcome in treatment of severe, degenerative pantalar deformities. This data may be useful in counselling patients when considering salvage versus amputation in such cases. Level of evidence Level 3(Original) Clinical Research Article.

Abstract: OBJECTIVE Suprasellar meningioma resection via either the transcranial approach (TCA) or the endoscopic endonasal approach (EEA) is an area of controversy and active evaluation. Skull base surgeons increasingly consider patient-reported outcomes (PROs) when choosing an approach. No PRO measure currently exists to assess quality of life for suprasellar meningiomas. METHODS Adult patients undergoing suprasellar meningioma resection between 2013 and 2019 via EEA (n = 14) or TCA (n = 14) underwent semistructured interviews. Transcripts were coded using a grounded theory approach to identify themes as the basis for a PRO measure that includes all uniquely reported symptoms. To assess content validity, 32 patients and 15 surgeons used a Likert scale to rate the relevance of items on the resulting questionnaire and the general Patient-Reported Outcomes Measurement Information System–29 (PROMIS29). The mean scores were calculated for all items and compared for TCA versus EEA patient cohorts by using unpaired t-tests. Items on either questionnaire with mean scores ≥ 2.0 from patients were considered meaningful and were aggregated to form the novel Suprasellar Meningioma Patient-Reported Outcome Survey (SMPRO) instrument. RESULTS Qualitative analyses resulted in 55 candidate items. Relative to patients who underwent the EEA, those who underwent the TCA reported significantly worse future outlook before surgery (p = 0.01), tiredness from medications 2 weeks after surgery (p = 0.001), and word-finding and memory difficulties 3 months after surgery (p = 0.05 and < 0.001, respectively). The items that patients who received a TCA were most concerned about included medication-induced lethargy after surgery (2.9 ± 1.3), blurry vision before surgery (2.7 ± 1.5), and difficulty reading due to blurry vision before surgery (2.7 ± 2.7). Items that patients who received an EEA were most concerned about included blurry vision before surgery (3.5 ± 1.3), difficulty reading due to blurry vision before surgery (2.4 ± 1.3), and problems with smell postsurgery (2.9 ± 1.3). Although surgeons overall overestimated how concerned patients were about questionnaire items (p < 0.0005), the greatest discrepancies between patient and surgeon relevance scores were for blurry vision pre- and postoperatively (p < 0.001 and < 0.001, respectively) and problems with taste postoperatively (p < 0.001). Seventeen meningioma-specific items were considered meaningful, supplementing 8 significant PROMIS29 items to create the novel 25-item SMPRO. CONCLUSIONS The authors developed a disease- and approach-specific measure for suprasellar meningiomas to compare quality of life by operative approach. If demonstrated to be reliable and valid in future studies, this instrument may assist patients and providers in choosing a personalized surgical approach.

Abstract: Aim Early diagnosis of colorectal cancer (CRC) improves outcome. Straight-To-Test (STT) pathway was introduced in Whittington Hospital in 2012. The aim was to reduce the time to first oncological treatment and minimise unnecessary outpatient clinic appointments. However, this pathway has added significant burden to the trust in terms of number of procedures to be done.We assessed the diagnostic yield and the effectiveness of this pathway in improving the time to diagnosis of colorectal cancer. We also performed a cost-effective analysis and discussed the current literature along with interventions to further improve the benefits of STT investigations. Method This is a prospectively collected data of all patients who underwent STT examinations in a single centre from January 2012 till December 2018. The parameters collected were patient details, procedures performed, findings and discharge plan. We also performed a cost-effective analysis. Results A total 1648 (90.8%) of patients identified suitable for STT pathway underwent colonoscopy or flexible sigmoidoscopy. From this, 764 (50.2%) patients had diagnosed pathology and CRC was detected in 50(3%) of the patients. We also estimated annual savings of £ 21,599.54 (£151,196.76 in seven years). Patients on the STT pathway took 25 days to obtain results as compared to 40 days in the standard pathway. The decision to take the patient off the cancer pathway was shortened by 3 weeks. Conclusion STT pathway has proven to be safe and cost-effective means of investigation. However, further improvement is needed in the implementation to make it a sustainable. mode of investigation in long run and increase the pickup rate of colorectal cancer through STT.

Abstract: We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p=0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3days, with an OR (95%CI) at 4–7days or ≥8days of 1.25 (1.04–1.48), p=0.015 and 1.31 (1.11–1.55), p=0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.

Abstract: Study Design: Retrospective pilot study.Purpose: To assess the incidence of renal tract abnormalities using ultrasonography (US) in a military cohort with traumatic spinal cord injury (TSCI) at a tertiary level spinal cord injury center.Overview of Literature: Neurogenic bladder in TSCI patients results in significant urological morbidity. There is lack of data for these patients during the first 18 months of long-term rehabilitation in an institutional setting.Methods: We retrospectively reviewed patient records to collect data on demographic characteristics, injury level, injury severity, time since injury, bladder management methods (such as an indwelling catheter [IC], clean intermittent catheterization [CIC], or self-voiding [S]); we correlated these data with the findings of the renal tract US.Results: The study included 73 out of 81 male participants. The mean patient age was 29.99 years; the study group included 34.2% tetraplegics and 65.8% people with paraplegia. The time since injury was 6–12 months for 42.5% of the subjects and 12–18 months for 57.5% of the subjects. A normal US scan was recorded in 65.7% patients, and bladder trabeculation was the commonest finding in 15.1% of the subjects, followed by hydronephrosis (HDN) in 12.3%, and renal calculus and atrophy in 1.3% participants each. We found 22.22% of the IC group participants had higher US abnormalities than those in the reflex voiding group (statistically non-significant difference, p=0.7). Trabeculations (21.4%) and HDN (19%) were more common in those who had sustained the injury 12–18 months previously as compared to that in those who had injured themselves 6–12 months previously (p=0.04). The proportion of patients who had a normal US scan was higher in the group who sustained the injury 6–12 months previously versus those who had sustained the injury 12–18 months previously; the difference was statistically significant (p=0.02). There was no significant (p=0.72) correlation in the bladder management method, injury level, and renal tract abnormalities between the groups.Conclusions: This retrospective study shows that 65% of TSCI participants had no renal tract abnormality on US scan and bladder trabeculation ruled out as the most common finding. Long-term supervised rehabilitation may help achieve good renal quality of life; however, further prospective trials are required on this subject.

Abstract: To identify discrete clusters of systemic lupus erythematosus (SLE) patients based on symptoms and investigate differences across clusters.Data were collected in the US and 5 European countries via the Adelphi Real World Lupus Disease Specific Programme, a cross-sectional survey. Rheumatologists provided data for 5 consecutively consulting adult patients with SLE, who were invited to participate. Identified SLE symptoms were reduced to factors based on commonly concurrent symptoms, using principal-component factor analysis. Factors were used as covariates in a latent-class cluster analysis to identify discrete patient clusters. Patient-reported outcomes and physician-reported data were compared across clusters.Among 1,376 patients, 87% were female and 74% were White. We identified 4 patient clusters (very mild, mild, moderate, and severe) based on 39 signs/symptoms. Physician-reported symptom burden, organ involvement, disease activity, and the number of flares increased with increasing cluster severity (P 0.0001). Patient-reported impact (health status, fatigue, work productivity impairment, anxiety/depression, and emotional impact) increased with increasing cluster severity (P 0.0001). Glucocorticoid and immunosuppressant use increased, and antimalarial use decreased, with increasing cluster severity. In all clusters,20% of patients received biologics;15% of patients not receiving biologics were considered eligible for treatment by their physician. The proportion of physicians and patients satisfied with treatment decreased with increasing cluster severity (P 0.0001).Our large, international, real-world survey of SLE patients and physicians demonstrated strong associations between increased impairment, organ involvement, and humanistic burden in SLE, highlighting an unmet need for effective treatment options in patients with high disease activity.

Abstract: Background Bariatric surgery can influence the presentation, diagnosis, and management of gastrointestinal cancers. Oesophago-Gastric (OG) malignancies in patients who have had a prior bariatric procedure have not been fully characterised. Objective To characterise OG malignancies after bariatric procedures. Setting University Hospital, United Kingdom. Methods We performed a retrospective, multi-centre observational study of patients with OG malignancies after bariatric surgery to characterise this condition. Results This study includes 170 patients from 75 centres in 25 countries who underwent bariatric procedures between 1985 and 2020. At the time of the bariatric procedure, the mean age was 50.2 ± 10 years and the mean weight 128.8 ± 28.9 kg. Females comprised 57.3% (n=98) of the population. Most (n=64) patients underwent a Roux-en-Y Gastric Bypass (RYGB) followed by Adjustable Gastric Band (AGB) (n = 46) and Sleeve Gastrectomy (SG) (n = 43). Time to cancer diagnosis after bariatric surgery was 9.5 ± 7.4 years and mean weight at diagnosis was 87.4 ± 21.9 kg. The time lag was 5.9 ± 4.1 years after SG compared to 9.4 ± 7.1 years after RYGB and 10.5 ± 5.7 years after AGB. One-third of patients presented with metastatic disease. The majority of tumours were adenocarcinoma (82.9%). Approximately 1 in 5 patients underwent palliative treatment from the outset. Time from diagnosis to mortality was under one year for most patients who died over the intervening period. Conclusions The OGMOS (Oesophago-Gastric Malignancies after Obesity/ Bariatric Surgery) study presents the largest series to date of patients developing OG malignancies after bariatric surgery and attempts to characterise this condition.

Abstract: Paediatric spontaneous pneumothorax (PSP) management continues to lack paediatric-specific guideline recommendations. There have been increasing reports of paediatric retrospective case studies supplemented by important well designed RCT (predominantly) adult studies. Taken together, these suggest that conservative management may have an increasing role to play in the management of PSP and that aspiration may have limited utility as a first line intervention. Our local experience, as part of a multicentre retrospective analysis and subsequent audit of management since, corroborates recent published data: it highlights an increasing trend towards conservative management in spontaneous pneumothorax with similar rates of recurrence, compared to intervention, and low use of aspiration with similarly low success rates. We have therefore updated our local practice guidelines and share these with readers. Specifically, we have removed aspiration in the management of primary spontaneous pneumothorax and reserved intervention for children who are clinically unstable or show evidence of increasing air leak irrespective of pneumothorax size. Whilst the success of this change in clinical practice will need to be reviewed in the next 5–10 years, the overall low incidence of the condition, demands a multicentre, and probably multinational, collaborative approach to allow the best chance of obtaining definitive evidence to guide clinical paediatric management.

Abstract: Advanced heart failure affects tens of thousands of people in the United States alone with high morbidity and mortality. Cardiac transplantation offers the best treatment strategy, but has been limited historically by donor availability. Recently, there have been significant advances in organ allocation, donor-recipient matching, organ preservation, and expansion of the donor pool. The current heart allocation system prioritizes the sickest patients to minimize waitlist mortality. Advances in donor organ selection, including predicted heart mass calculations and more sophisticated antibody detection methods for allosensitized patients, offer more effective matching of donors and recipients. Innovations in organ preservation such as with organ preservation systems have widened the donor pool geographically. The use of donors with hepatitis C is possible with the advent of effective direct-acting antiviral agents to cure donor-transmitted hepatitis C. Finally, further expansion of the donor pool is occurring with the use of higher risk donors with advanced age, medical comorbidities, and left ventricular dysfunction and advances in donation after circulatory death. This review provides an update on the new technologies and transplantation strategies that serve to widen the donor pool and more effectively match donors and recipients so that heart transplant candidates may derive the best outcomes from heart transplantation.

Abstract: Since the invention of the computer, all available information in every field has been digitized and made available to people who use computer resources. As a result, massive amounts of data are being generated in every domain at an alarming rate. Agriculture is one such area of interest for researchers. Machine learning is the process of extracting useful information from various types of data. The classification of objects is an important area within the field of data mining, and its application extends to a variety of areas, whether or not in the field of science. Although k-Nearest Neighbor classification is a simple and effective technique, it slows down the classification of each object. Furthermore, the classification’s effectiveness suffers as a result of the uneven distribution of training data. The purpose of this paper is to look into the applicability of various machine learning techniques in agriculture.

Abstract: This study sought to determine whether stress cardiac magnetic resonance (CMR) provides clinically relevant risk reclassification in patients with known coronary artery disease (CAD) in a multicenter setting in the United States.Despite improvements in medical therapy and coronary revascularization, patients with previous CAD account for a disproportionately large portion of CV events and pose a challenge for noninvasive stress testing.From the Stress Perfusion Imaging in the United States (SPINS) registry, we identified consecutive patients with documented CAD who were referred to stress CMR for evaluation of myocardial ischemia. The primary outcome was nonfatal myocardial infarction (MI) or cardiovascular (CV) death. Major adverse CV events (MACE) included MI/CV death, hospitalization for heart failure or unstable angina, and late unplanned coronary artery bypass graft. The prognostic association and net reclassification improvement by ischemia for MI/CV death were determined.Out of 755 patients (age 64 ± 11 years, 64% male), we observed 97 MI/CV deaths and 210 MACE over a median follow-up of 5.3 years. Presence of ischemia demonstrated a significant association with MI/CV death (HR: 2.30; 95% CI: 1.54-3.44; P 0.001) and MACE (HR: 2.24 ([95% CI: 1.69-2.95; P0.001). In a multivariate model adjusted for CV risk factors, ischemia maintained strong association with MI/CV death (HR: 1.84; 95% CI: 1.17-2.88; P = 0.008) and MACE (HR: 1.77; 95% CI: 1.31-2.40; P 0.001) and reclassified 95% of patients at intermediate pretest risk (62% to low risk, 33% to high risk) with corresponding changes in the observed event rates of 1.4% and 5.3% per year for low and high post-test risk, respectively.In a multicenter cohort of patients with known CAD, CMR-assessed ischemia was strongly associated with MI/CV death and reclassified patient risk beyond CV risk factors, especially in those considered to be at intermediate risk. Absence of ischemia was associated with a2% annual rate of MI/CV death. (Stress CMR Perfusion Imaging in the United States [SPINS] Study; NCT03192891).

Abstract: Belleville springs are frusto-conical in shape, can support high load with small deflection. Load-Deflection characteristics of a Belleville spring can be altered by stacking of springs. In this research work, Finite Element Analysis (FEA) of Belleville spring was carried out and compared against experimental analysis using strain gauge. FEA was carried out on a plain spring and results were compared with theoretical analysis. Experimental investigation was carried out using strain gauges for different configuration of Belleville springs such as plain spring and spring with stacking. From the studies it was concluded that theoretical, Finite Elemental and Experimental analyses were in good agreement. Spring stacking was done up to 6 numbers, and deflection was significantly altered from 1.46 mm to 8.14 mm (Deflection from one spring to six springs). With the stacking of springs, change in the magnitude of maximum stress was 1.5%. Thus, required load- deflection characteristics can be achieved by stacking of springs when space is not a constraint and large deflection is required.

Abstract: Diabetes is a significant public health issue. The global diabetes epidemic has had a tremendous impact on India, and the disease burden has increased dramatically. Diabetes is quickly increasing in prevalence, especially in Indian cities, according to data. Therefore, an ideal drug is sought that has better safety and tolerability and the most effective control of diabetes. Many effective medications come from plant sources. Natural products like onion and garlic can effectively control diabetes. In this review, we should pay attention to Aloe vera and its bioactive compounds, that with the development of traditional medicine, Aloe vera can be used to treat various diseases. Some reports have questioned the safety and efficacy of Aloe vera or its compounds, especially at different doses, and some studies have shown no side effects. In this review we also focus on benefits on human health so that Aloe vera is part of the daily diet in many countries and appears to be non-toxic, it is necessary to investigate whether aloe vera dietary supplement can be a beneficial preventive or nutritional mitigation strategy to reduce the effects of diabetes. This review focuses on Aloe vera and its biologically active compounds that play a role in the treatment or prevention of this morbid disease: diabetes, including its underlying mechanism of blood sugar lowering properties, and herbal products that have been marketed for the treatment of diabetes or the therapeutic effect of diabetes.

Abstract: Fixed site monitoring is the primary method of measuring surface ozone pollution for health advisories and pollutant reduction, but the spatial scale may not reflect the current population distribution or its future growth. Moreover, formal methods for the placement of ozone monitoring sites within populations regions omit important spatial criteria producing monitoring locations that could unintentionally bias the exposure burden. Because ozone pollution endangers human health, triggering shortness of breath, causing asthma attacks and mortality, a need exists for assessing the spatial representativeness and data gaps of existing pollution monitors and to evaluate future placement strategies of additional monitors. A new metric, the potency index, for assessing the placements of monitors in relation to population distribution was developed. This index was used to evaluate the configuration of the ozone pollution monitoring network in relation to the population distribution in Dallas-Fort Worth (DFW). Location-allocation models were used to optimize future sensor quantity and placement. Finally, we propose the development of a decision support system that uses evaluation and optimization methods to improve air pollution monitoring objectives.

Abstract: PURPOSE: Clinical models to identify patients at high risk of primary graft dysfunction (PGD) after heart transplantation (HT) are limited, and the underlying pathophysiology of this common post-transplant complication remains poorly understood. We sought to identify whether pre-transplant levels of circulating proteins reporting on immune activation and inflammation are associated with incident PGD. METHODS: The study population consisted of 219 adult heart transplant recipients identified between 2016 and 2020 at Duke University Medical Center, randomly divided into derivation (n = 131) and validation (n = 88) sets. PGD was defined using modified ISHLT criteria. Proteomic profiling was performed using Olink panels (n = 354 proteins) with serum samples collected immediately prior to transplantation. Association between normalized relative protein expression and PGD was tested using univariate and multivariable (recipient age, creatinine, mechanical circulatory support, and sex; donor age; ischemic time) models. Significant proteins identified in the derivation set (p < 0.05 in univariate models), were then tested in the validation set. Pathway enrichment analysis was used to test candidate biological processes. The predictive performance of proteins was compared to that of the RADIAL score. RESULTS: Nine proteins were associated with PGD in univariate models in the derivation set. Of these, only CLEC4C remained associated with PGD in the validation set after Bonferroni correction (OR [95% CI] = 3.04 [1.74,5.82], p = 2.8×10(−4)). Patterns of association were consistent for CLEC4C in analyses stratified by biventricular/left ventricular and isolated right ventricular PGD. Pathway analysis identified interferon-alpha response and C-type lectin signaling as significantly enriched biologic processes. The RADIAL score was a poor predictor of PGD (AUC = 0.55). CLEC4C alone (AUC = 0.66, p = 0.048) and in combination with the clinical covariates from the multivariable model (AUC = 0.69, p = 0.018) improved discrimination for the primary outcome. CONCLUSIONS: Pre-transplantation circulating levels of CLEC4C, a protein marker of plasmacytoid dendritic cells (pDCs), may identify HT recipients at risk for PGD. Further studies are needed to better understand the potential role pDCs and the innate immune response in PGD.

Abstract: Obesity and associated comorbidities reach epidemic proportions nowadays. Several treatment strategies exist, but bariatric surgery has the only longstanding effects. Since a few years, there is increasing interest in the effects of gastro-intestinal hormones, in particular Glucagon-Like Peptide-1 (GLP-1) on the remission of Type 2 Diabetes (T2DM) and its effects on cardiac cardiovascular morbidity, cardiac remodelling and mortality. In the past years several high quality multicentre randomised controlled trials were developed to assess the effects of GLP-1 receptor agonist therapy on cardiovascular morbidity and mortality. Most of the trials were designed and powered as non-inferiority trials to demonstrate cardiovascular safety. The majority of these trials show a reduction in cardiovascular morbidity in patients with T2DM. Some follow-up studies indicate potential beneficial effects of GLP-1 receptor agonists on cardiovascular function in patients with heart failure, however the results are contradictory and we are in need of long-term studies to make firm conclusions about the pleiotropic properties of incretin-based therapies. However it seems that GLP-1 receptor agonists have different effects than the increased GLP-1 production after bariatric surgery on cardiovascular remodelling. One of the hypothesis is that the blood concentrations of GLP-1 receptor agonists are three times higher compared to GLP-1 increase after bariatric and metabolic surgery. The purpose of this narrative review is to summarise the effects of GLP-1 on cardiovascular morbidity, mortality and remodelling due to medication but also due to bariatric and metabolic surgery. The second objective is to explain the possible differences in effects of GLP-1 agonists and bariatric and metabolic surgery.

Abstract: BACKGROUND: Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain. METHODS: We randomly assigned 5179 patients with moderate or severe ischemia to an initial invasive strategy (angiography and revascularization when feasible) and medical therapy or to an initial conservative strategy of medical therapy alone and angiography if medical therapy failed. The primary outcome was a composite of death from cardiovascular causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. A key secondary outcome was death from cardiovascular causes or myocardial infarction. RESULTS: Over a median of 3.2 years, 318 primary outcome events occurred in the invasive-strategy group and 352 occurred in the conservative-strategy group. At 6 months, the cumulative event rate was 5.3% in the invasive-strategy group and 3.4% in the conservative-strategy group (difference, 1.9 percentage points; 95% confidence interval [CI], 0.8 to 3.0); at 5 years, the cumulative event rate was 16.4% and 18.2%, respectively (difference, -1.8 percentage points; 95% CI, -4.7 to 1.0). Results were similar with respect to the key secondary outcome. The incidence of the primary outcome was sensitive to the definition of myocardial infarction; a secondary analysis yielded more procedural myocardial infarctions of uncertain clinical importance. There were 145 deaths in the invasive-strategy group and 144 deaths in the conservative-strategy group (hazard ratio, 1.05; 95% CI, 0.83 to 1.32). CONCLUSIONS: Among patients with stable coronary disease and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of ischemic cardiovascular events or death from any cause over a median of 3.2 years. The trial findings were sensitive to the definition of myocardial infarction that was used.

27. The Anisotropic Yield Surface of Cellular Materials

Abstract: The use of mechanical metamaterials in engineering applications is often limited because of uncertainty regarding their deformation behavior. This uncertainty necessitates large safety factors and assumptions about their behavior to be included in mechanical designs including metamaterials, which detracts from their greatest benefit, viz. their ultralight weight. In this study, a yield envelope was created for both a bending-dominated and a stretching-dominated cellular material topology to improve the understanding of the response of cellular materials under various load types and orientations. Experimental studies revealed that the shear strength of a cellular material is significantly lower than that predicted by Mohr’s criterion, necessitating a modification of the Mohr’s yield criterion for cellular materials. All topologies experienced tension–compression anisotropy and topology orientation anisotropy during loading, with the stretching-dominated topology experiencing the largest anisotropies.

Abstract: Aim: To compare the outcome of intermittent phototherapy versus continuous phototherapy in treatment of neonatal jaundice. Study Design: Randomized clinical trial (RCT). Place and Duration: This study was conducted at Department of pediatrics, neonatal ward, Liaquat university hospital Hyderabad/Jamshoro, from 8 January to 7 July 2020 Methodology: There were 222 neonate with jaundice, which were randomly allocated into two groups. One hundred and one neonates were in group “A” who received continuous phototherapy while 111 neonates were treated with intermittent phototherapy called group B. Phototherapy units were identical regarding their manufacture and radiance with 5 blue light tubes at a distance of 15-20 cm above neonate that produced the irradiance of 20µW/cm2/nm at 420-470 nm. Serum bilirubin levels were measured every 12 hourly after starting phototherapy up to 48 hours. SPSS version 22 was used for data analysis. Results: The average age of the neonates was 2.23±1.45 days. In this study, the reduction of bilirubin level in both groups after 12, 24, 36, 48 hours of phototherapy and at the time of discharge was not different between groups. Conclusion: Intermittent and continuous phototherapies were found to be equally effective. Because of its additional benefits, intermittent phototherapy can be adopted as a routine procedure instead of continuous phototherapy in neonatal care units, however, it needs to be confirmed by large scale RCTs.

Abstract: Introduction: World Health Organization (WHO) in 2014 recommended delayed cord clamping (DCC) in all babies who cry immediately after birth. Despite many benefits, there are concerns of increased rate of phototherapy in babies receiving DCC. This study was done to determine the increment in the rate of phototherapy required in infants managed with DCC vs infants managed with early cord clamping (ECC). Methods: A retrospective observational study was conducted in a tertiary care hospital in Pune, India. All the infants born between January 2018 and July 2018, for whom ECC was done, were compared with infants who were born between January 2019 and July 2019, after DCC policy was adopted. All the infants with birth weight ≥2 kg and gestation ≥35 weeks, who were with their mother, were included. Baseline characteristics were compared for both the groups. American Academy of Pediatrics guidelines for treatment of neonatal jaundice were used to determine the need for phototherapy. Number of infants in both the groups who required phototherapy were compared. Results: The ECC group had 565 infants while DCC group had 731 infants. There was no difference in the baseline characteristics of the 2 groups. Jaundice requiring phototherapy was noted in 31% of infants in the ECC group, compared to 45% in infants in the DCC group (relative risk: 1.47 [1.27-1.71] [ P < .001]). Conclusion: In this study, DCC increased the need for phototherapy by 47% in late preterm and term infants. Randomized control trials with larger sample size are required to confirm this finding.

Subjects: medicine.medical_specialty, business.industry, Lower lip, medicine, Basal cell, business, medicine.disease, Oral cavity, Primary tumor, Surgery
Abstract: Background: Clear surgical margins are of utmost importance in surgical oncological procedures. Secondary consideration includes the functional and aesthetic outcomes of the patients after the procedure. The recognised surgical approach to the posteriorly located oral cavity and oropharyngeal tumors involves the splitting of the lower lip with or without mandibulectomy. In order to perk up postoperative function and aesthetics, quite a lot of modiﬁcations of the unique midline lower lip-splitting incision have been projected by various authors till date. A stepped ladder lower lip split incision (LLSI) helps in improved functional and aesthetic outcomes. Objectives: The prime accent of the study is to compare the McGregor LLSI and the stepped LLSI with respect to functional and aesthetic outcomes in tumors ablation for SCCOC. Methodology: The study population (n=22) is assigned randomly in two equal groups as a subject in the ratio of 1:1. Systemically healthy histologically diagnosed patients of SCCOC requiring LLSI for the tumours ablation will be included. In Group A- McGregor LLSI will be performed and in Group B- a Stepped LLSI would performed. Post-operative assessment of functional and aesthetic outcomes will be done. Expected Results: A stepped ladder LLSI used for tumours ablation will be effective in preserving post-operative lip movement, lip competency and cosmesis. Conclusion: Utility of a Stepped ladder LLSI for accessibility and ablation of posterior oral and oropharyngealtumors would be undoubtfully beneficial for improving post-operative functional and aesthetic outcomes and could be executed in routine oncologic surgery.

Abstract: Objective To report the 30-day outcomes of patients with perioperative SARS-CoV-2 infection undergoing surgery in the USA. Summary background data Uncertainty regarding the postoperative risks of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exists. Methods As part of the COVIDSurg multicenter study, all patients aged ≥17 years undergoing surgery between January 1 and June 30, 2020 with perioperative SARS-CoV-2 infection in 70 hospitals across 27 states were included. The primary outcomes were 30-day mortality and pulmonary complications. Multivariable analyses (adjusting for demographics, comorbidities, and procedure characteristics) were performed to identify predictors of mortality. Results A total of 1,581 patients were included; more than half of them were males (n= 822, 52.0%) and older than 50 years (n=835, 52.8%). Most procedures (n=1,261, 79.8%) were emergent, and laparotomies (n= 538, 34.1%). The mortality and pulmonary complication rates were 11.0 and 39.5%, respectively. Independent predictors of mortality included age ≥70 years (OR 2.46, 95% CI [1.65-3.69]), male sex (2.26 [1.53-3.35]), ASA grades 3-5 (3.08 [1.60-5.95]), emergent surgery (2.44 [1.31-4.54]), malignancy (2.97 [1.58-5.57]), respiratory comorbidities (2.08 [1.30-3.32]), and higher Revised Cardiac Risk Index (1.20 [1.02-1.41]). While statewide elective cancelation orders were not associated with a lower mortality, a sub-analysis showed it to be associated with lower mortality in those who underwent elective surgery (0.14 [0.03-0.61]). Conclusions Patients with perioperative SARS-CoV-2 infection have a significantly high risk for postoperative complications, especially elderly males. Postponing elective surgery and adopting non-operative management, when reasonable, should be considered in the USA during the pandemic peaks.

Abstract: We recently published in GUT the outcomes of acute pancreatitis (AP) and coexisting SARS-CoV-2 infection.1 A number of patients who were SARS-CoV-2 positive had AP of unknown aetiology (25%) speculating SARS-CoV-2 as a cause for AP similar to other viruses.2 However, most patients did not complete investigations to exclude other causes of AP. In addition, SARS-CoV-2 infection may cause aberrant glycometabolic control,3 however it is unknown if this increases the risk of long-term diabetes mellitus (DM). The follow-up data were collected 12 months from the date of recruitment for 1476 patients (118 patients who were SARS-CoV-2 positive and 1358 patients who were negative) to establish an aetiology for AP and development of DM. Among the 118 patients who were SARS-CoV-2 positive, 35 patients had idiopathic or unknown aetiology AP. Sixteen patients underwent either MRCP (n=13) or EUS (n=4) and the remaining patients underwent biochemical investigations to exclude other causes of AP. The final aetiology of AP was available for 83 (70.3%) patients and included gallstones (56, 47.4%), alcohol (19, 16.1%), post ERCP (2, 1.7%) and other (6, 5.1%). Overall, 23 patients had a change of aetiology, and in 35 (29.7%) patients AP was considered idiopathic. Patients who were SARS-CoV-2 positive were more likely to have idiopathic AP (34.7% vs 13.9%, p

Abstract: Background: Raised intracranial pressure (ICP) due to cerebral edema (CE) is central to development of hepatic encephalopathy in acute liver failure (ALF). Mannitol (MT) and hypertonic saline (HS) have been shown to improve CE. We compared the efficacy and safety of the 2 modalities. Methods: ALF with CE was prospectively randomized in an open study to receive either 5 mL/kg of either 3% HS, as continuous infusion; titrated every 6 hourly to achieve serum sodium of n = 26) or 1 g/kg of 20% MN as a IV bolus, repeated every 6 hourly (Group B; n = 25) in addition to standard ALF care. Primary end-point was reduction of ICP defined as optic nerve sheath diameter Results: Fifty-one patients with ALF, hepatitis E being commonest (33.3%), median jaundice to HE interval of 8 (1–16) days, were randomized to HS (n = 26) or MN (n = 25). Baseline characteristics were comparable including King’s college criteria (>2: 38.4% vs.40%). Overall, 61.5% patients in the HS and 56% in the MN group showed reduction in ICP at 12 h (p = 0.25). Rebound increase in ICP indices was noted in 5 (20%) patients in MT and none in HS (p < 0.05) group. New onset acute kidney injury was common in the MT group than in the HS group. The ICU stay and 28-day transplant-free survival were not different between the groups. Conclusions: While both agents had comparable efficacy in reducing ICP and mortality in ALF patients was comparable, HS was significantly better in preventing reducing rebound CE with lower renal dysfunction.

Abstract: Stress-induced dopaminergic (DAergic) neuronal death in the midbrain region is the primary cause of Parkinson's disease (PD). Following the discovery of l-dopa, multiple drugs have been developed to improve the lifestyle of PD patients; however, none have been suitable for clinical use due to their multiple side effects. Tinospora cordifolia has been used in traditional medicines to treat neurodegenerative diseases. Previously, we reported the neuroprotective role of Tc via inhibition of NF-κB-associated proinflammatory cytokines against MPTP-intoxicated Parkinsonian mice. In the present study, we investigated the neuroprotective molecular mechanism of Tc in a rotenone (ROT)-intoxicated mouse model, using a proteomics approach. Mice were pretreated with Tc extract by oral administration, followed by ROT intoxication. Behavioral tests were performed to check motor functions of mice. Protein was isolated, and label-free quantification (LFQ) was carried out to identify differentially expressed protein (DEP) in control vs PD and PD vs treatment groups. Results were validated by qRT-PCR with the expression of target genes correlating with the proteomics data. In this study, we report 800 DEPs in control vs PD and 133 in PD vs treatment groups. In silico tools demonstrate significant enrichment of biochemical and molecular pathways with DEPs, which are known to be important for PD progression including mitochondrial gene expression, PD pathways, TGF-β signaling, and Alzheimer's disease. This study provides novel insights into the PD progression as well as new therapeutic targets. More importantly, it demonstrates that Tc can exert therapeutic effects by regulating multiple pathways, resulting in neuroprotection.

Abstract: Facial expression plays an important role in communicating emotions. In this paper, a robust method for recognizing facial expressions is proposed using the combination of appearance features. Traditionally, appearance features mainly divide any face image into regular matrices for the computation of facial expression recognition. However, in this paper, we have computed appearance features in specific regions by extracting facial components such as eyes, nose, mouth, and forehead, etc. The proposed approach mainly has five stages to detect facial expression viz. face detection and regions of interest extraction, feature extraction, pattern analysis using a local descriptor, the fusion of appearance features and finally classification using a Multiclass Support Vector Machine (MSVM). Results of the proposed method are compared with the earlier holistic representations for recognizing facial expressions, and it is found that the proposed method outperforms state-of-the-art methods.

Abstract: This article reports design and testing of silicon carbide) devices-based three-phase asymmetric H-bridge converter capable of switching at 50 kHz and intended to drive high-speed switched reluctance machine. Electromagnetic designs of a 7.5-kW, 30 000-r/min and a 20-kW, 50 000-r/min Switched reluctance machine are presented. The 30 000-r/min machine is fabricated and characterized. A machine model is obtained from the measured characteristics. Based on the machine model, as well as drive operating variables and device data-sheet parameters, two methods are proposed for evaluating the losses in the power devices. The first method relies on machine model to obtain machine current and converter duty ratio, and thereby estimate the device losses. A second simplified method provides closed-form expressions for device losses. The proposed analytical expressions relate the machine characteristics such as inductance and saturation current with converter losses. The estimated loss is further used to predict device junction temperature. The power converter and device ratings are chosen so that the converter is suitable for both machines. The capacitor selection and sizing are discussed. Further, the power converter architecture and other subsystems of the converter are described. Test results are presented for the asymmetric H-bridge converter at 800 V dc bus voltage, 50 A of load current, and 50 kHz of switching frequency. Thermal image is presented for validation of estimated heat-sink temperature. The predicted heat-sink temperature is found to agree well with the measured temperature. The power converter is used to operate the 30 000-r/min machine at various speeds.

Abstract: Objectives Monitoring the antibody responses to SARS-CoV-2 infection and its correlation to clinical spectrum of disease is critical in understanding the disease progression and protection against re-infection. We assessed the nucleocapsid (N) and receptor-binding-domain of spike (SRBD) protein specific IgG and neutralizing antibody (NAb) responses in COVID-19 patients up to 8 months and its correlation with diverse disease spectrum. Methods During the first wave of the SARS-CoV-2 pandemic, from 284 COVID-19 patients, 608 samples were collected up to 8 months post infection. The patients were categorized as asymptomatic, symptomatic and severe. The N and SRBD IgG and NAb titers were evaluated and correlated with clinical data. Results A steep increase in antigen specific antibody titers was observed till 40 days post onset of the disease (POD), followed by a partial decline till 240 days. Severe disease was associated with a stronger SRBD IgG response and higher NAb titers. The persistence of antibody response was observed in 76% against N, 80% against SRBD and 80% for NAbs of cases up to 8 months POD. Conclusion RBD and N protein specific IgG persisted till 240 days POD which correlated with NAb response, irrespective of individual`s symptomatic status indicating overall robust protection against re-infection.

Abstract: The COVID-19 pandemic had a devastating impact on the human health and global economy. The food and agriculture sectors have also felt these effects. In many countries, the measures taken to curb the spread of the virus were initiated to hinder the supply of agricultural products to markets and consumers inside and outside the borders. How this impacts the food safety, nutrition, and the livelihoods of farmers, fishermen, and others working in the food supply chain depends mainly on short-, medium-, and long-term policy responses. Epidemics pose severe challenges to the food system in the short term, but they also offer an opportunity to face challenges and accelerate the transformation of the food and agricultural sectors to increase resilience. The aim of the review was to highlight the valuable insight on the impact of COVID-19 on the Indian agricultural system and rural economy, as well as potential strategies for post-pandemic recovery.

Abstract: Children and adolescents infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are predominantly asymptomatic or have mild symptoms compared with the more severe coronavirus disease 2019 (COVID-19) described in adults. However, SARS-CoV-2 is also associated with a widely reported but poorly understood paediatric systemic vasculitis. This multisystem inflammatory syndrome in children (MIS-C) has features that overlap with myocarditis, toxic-shock syndrome and Kawasaki disease. Current evidence indicates that MIS-C is the result of an exaggerated innate and adaptive immune response, characterized by a cytokine storm, and that it is triggered by prior SARS-CoV-2 exposure. Epidemiological, clinical and immunological differences classify MIS-C as being distinct from Kawasaki disease. Differences include the age range, and the geographical and ethnic distribution of patients. MIS-C is associated with prominent gastrointestinal and cardiovascular system involvement, admission to intensive care unit, neutrophilia, lymphopenia, high levels of IFNγ and low counts of naive CD4+ T cells, with a high proportion of activated memory T cells. Further investigation of MIS-C will continue to enhance our understanding of similar conditions associated with a cytokine storm., In this timely Review, the authors compare and contrast two forms of childhood inflammatory vasculitis: Kawasaki disease and the coronavirus disease 2019 (COVID-19)-associated multisystem inflammatory syndrome in children, highlighting epidemiological, clinical and immunological differences that suggest they should be classified as distinct syndromes., Key points Multisystem inflammatory syndrome in children (MIS-C) is characterized by exaggerated innate and adaptive immune responses following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in predisposed children.Clinical presentation of MIS-C involves multiple organ systems, with prominent involvement of the gastrointestinal and cardiovascular systems.The factors that trigger the development of MIS-C in children exposed to or infected with SARS-CoV-2 are not yet known.Results from epidemiological, clinical and immunological investigations have revealed that although MIS-C has phenotypic similarities to Kawasaki disease, they are different syndromes.The approach to treatment of MIS-C aims to mute the augmented inflammatory response.

Abstract: There exists a long-standing challenge of building successful research collaborations between industry and academia in software engineering. There are multiple reasons contributing to this issue, including different timelines, impact metrics, expectations, and perceptions of researchers and practitioners, altogether leading to the issue known as the industryacademia collaboration gap. After the onset of the COVID-19 pandemic, most researchers and practitioners were sent to work from home, relying on virtual collaboration with their peers, which might have given rise to an even wider industry-academia collaboration gap. At the 8th International Workshop on Software Engineering Research and Industrial Practice, held virtually at the International Conference on Software Engineering 2021, we investigate the impact that working from home has had on research collaborations between industry and academia. We also take a look at how remote work may change research collaborations in the future. In this report, we present takeaways from keynote talks on this matter, share insights from the panel of six experts on the topic of industry-academia collaborations, and finally summarize findings from related paper presentations.

Abstract: Internet of Things (IoT) and cloud computing are used in many real-time smart applications such as smart health-care, smart traffic, smart city, and smart industries. Fog computing has been introduced as an intermediate layer to reduce communication delay between cloud and IoT Devices. To improve performance of these smart applications, a predictive maintenance system needs to adopt anomaly detection and root cause analysis model that helps to resolve anomalies and avoid such anomalies in future. The state-of-art work on data-driven root cause analysis suffers from scalability, accuracy, and interpretability. In this paper, a multi-agent-based improved data-driven root cause analysis technique is introduced to identify anomalies and its root cause. Multiple agents are used to perform various operations like data collection, anomaly detection, and root cause analysis. The deep learning model LSTM autoencoder is used to find the anomalies, and a game theory approach called SHAP algorithm is used to find the root cause of the anomaly. The experiment is carried out in Google Colab with Keras Python library to evaluate the model. The evaluation result shows the improvement in accuracy and interpretability, as compared to state-of-the-art works.

Abstract: This article present wideband Metamaterial Cross Polarizer (MCP) structure for C and X band applications. The proposed structure consists of wheel shaped associated with meander line and triangular shaped patches having overall dimension of 18 × 18 mm. The anisotropic design patchis a single metallic layer (Cu) placed at the top of dielectric substrate FR-4 and backed by a ground also consists of metal layer (Cu). A wideband Polarization Conversion Ratio (PCR) above 0.8 magnitudes is achieved having bandwidth of 8.1 GHz ranging from 3.43 to 11.53 GHz and it works for C (4–8 GHz) and X (8–12 GHz) band approximately. The bandwidth of PCR at Full Width Half Maxima (FWHM) achieved is 8.24 GHz (3.60–11.84 GHz). Three distinct PCR peaks are observed at 4.2, 5.98, and 9.46 GHz with PCR magnitudes at 91.07, 96.39, and 99.76% respectively. Analysis of polarization conversion phenomena at these three frequencies is described with the help of current and electric field distribution. The proposed anisotropic structure is examined at different angles under normal and oblique incident. The simulation is performed through ANSYS HFSS (19.1), fabrication is done on substrate FR-4 using printed circuit board (PCB). The simulated and measured curves obtained for reflection coefficient and PCR are similar to one another with minute difference due to fabrication tolerances.

Abstract: Introduction Despite advances in modern medicine, brain tumor patients are still monitored purely by clinical evaluation and imaging. Traditionally, invasive strategies such as open or stereotactic biopsies have been used to confirm the etiology of clinical and imaging changes. Liquid biopsies can enable physicians to noninvasively analyze the evolution of a tumor and a patient’s response to specific treatments. However, as a consequence of biology and the current limitations in detection methods, no blood or cerebrospinal fluid (CSF) brain tumor-derived biomarkers are used in routine clinical practice. Enhancing the presence of tumor biomarkers in blood and CSF via brain-blood barrier (BBB) disruption with MRI-guided focused ultrasound (MRgFUS) is a very compelling strategy for future management of brain tumor patients. Methods A literature review on MRgFUS-enabled brain tumor liquid biopsy was performed using Medline/Pubmed databases and clinical trial registries. Results The therapeutic applications of MRgFUS to target brain tumors have been under intense investigation. At high-intensity, MRgFUS can ablate brain tumors and target tissues, which needs to be balanced with the increased risk for damage to surrounding normal structures. At lower-intensity and pulsed-frequency, MRgFUS may be able to disrupt the BBB transiently. Thus, while facilitating intratumoral or parenchymal access to standard or novel therapeutics, BBB disruption with MRgFUS has opened the possibility of enhanced detection of brain tumor-derived biomarkers. Conclusions In this review, we describe the concept of MRgFUS-enabled brain tumor liquid biopsy and present the available preclinical evidence, ongoing clinical trials, limitations, and future directions of this application.

Abstract: Objective Our primary objective was to develop an Outcome Measures in Rheumatology (OMERACT) core domain set to capture the impact of glucocorticoids (GC), both positive and negative, on patients with Rheumatic conditions. Methods The OMERACT Filter 2.1 was used to guide core domain selection. Systematic literature reviews, qualitative studies and quantitative surveys were conducted by the OMERACT GC Impact working group to identify candidate domains for a core domain set. A summary of prior work and Delphi exercise were presented at the OMERACT 2020 virtual GC workshop. A proposed GC Impact core domain set derived from this work was presented for discussion in facilitated breakout groups. Participants voted on the proposed GC Impact core domain set. Results 113 people, including 23 patient research partners, participated in two virtual workshops conducted at different times on the same day. The proposed mandatory domains to be evaluated in clinical trials involving GCs were: infection, bone fragility, hypertension, diabetes, weight, fatigue, mood disturbance and death. In addition, collection of disease specific outcomes was included in the core domain set as “mandatory in specific circumstances”. The proposed core domain set was endorsed by 100% (23/23) of the patient research partners and 92% (83/90) of the remaining participants, including clinicians, researchers and industry stakeholders. Conclusion A GC Impact core domain set was endorsed at the OMERACT 2020 virtual workshop. The OMERACT GC Impact working group will now progress to identify, develop and validate measurement tools to best address these domains in clinical trials.

Abstract: Aim: The current investigation is focused on the targeted delivery of doxorubicin through CD44 aptamer-mediated active targeting to the human breast cancer cells. Methods: CD44 aptamer-doxorubicin (Apt-Dox) conjugates were developed by incubating different molar ratios of aptamer and doxorubicin. Cytotoxicity, selective intracellular accumulation and uptake of the Apt–Dox conjugates were analyzed to evaluate the efficacy of Apt–Dox conjugates. Results: Dox was efficiently conjugated with aptamer at 1:2 Apt–Dox molar ratios. Apt–Dox conjugate significantly inhibited the proliferation of CD44-overexpressing breast cancer cells, whereas negligible inhibition of cell proliferation was found in the control cells. Apt–Dox conjugate selectively internalized and accumulated in CD44-overexpressing cells. Conclusion: Apt–Dox conjugate selectively delivers doxorubicin to CD44-expressing cancer cells, thereby inhibiting selective cell proliferation and enhancing the targeted therapy.

Abstract: Rapid technological advances have significantly improved the capability, versatility, and robustness of mass spectrometers which has led to them playing a central role in the development, characterization, and regulatory filings of biopharmaceuticals. Their application spans the entire continuum of drug development, starting with discovery research through product development, characterization, and marketing authorization and continues well into product life cycle management. The scope of application extends beyond traditional protein characterization and includes elements like clone selection, cell culture physiology and bioprocess optimization, investigation support, and process analytical technology. More recently, advances in the MS-based multi-attribute method are enabling the introduction of MS in a cGMP environment for routine release and stability testing. While most applications of MS to date have been for monoclonal antibodies, the successes and learnings should translate to the characterization of next-gen biotherapeutics where modalities like multispecifics could be more prevalent. In this review, we describe the most significant advances in MS and correlate them to the broad spectrum of applications to biotherapeutic development. We anticipate rapid technological improvements to continue that will further accelerate widespread deployment of MS, thereby elevating our overall understanding of product quality and enabling attribute-focused product development.
