Abstract
Abstract
Background
An audit was performed to identify the incidence and risk factors of post-operative abdominal fascial dehiscence after Exploratory laparotomy.
Methods
The prospectively maintained database of a single unit was reviewed.The demographic parameters, comorbidities, degree of contamination, type of procedures, and the types of suture & needles were reviewed.We analyzed the relation of the type of sutures, type of surgery and degree of contamination on the development abdominal fascial dehiscence within 30 days of surgery .Difference between the groups were analyzed by t tests for continuous variables and Chi squared tests for categorical variables.
Results
50 (17.7%) patients developed fascial dehiscence.Mean Albumin was 2.45 +/- 0.69 g/dl in the dehiscence group, compared to 2.97 +/- 0.86 g/dl in those without dehiscence (p= 0.00).The prevalence of diabetics, smokers and incidence of postoperative surgical site infection were significantly more in the patients with dehiscence (p value - 0.045, 0.043 and 0.00 respectively).Prevalence of class 4 wounds was higher in the group with dehiscence (70% vs 44%, p value 0.001).Type of suture used (Loop PDS No. 1 vs PDS 2–0) did not significantly influence development of facial dehiscence within 1 month.
Conclusion
Results of our study are consistent with existing literature. Important preoperative/intraoperative parameters such as smokingr, diabetics, preoperative hypovolemic shock, albumin are significant predictors of fascial dehiscence in the post operative period. This will enable surgeons to take corrective measures before the surgery

Assessing Bladder Radiotherapy Response With Quantitative Diffusion-Weighted Magnetic Resonance Imaging Analysis. Clin Oncol (R Coll Radiol) 2022; 34:630-641. [PMID: 35534398 DOI: 10.1016/j.clon.2022.04.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 03/13/2022] [Accepted: 04/01/2022] [Indexed: 11/28/2022]
Abstract
AIMS Radiotherapy with radiosensitisation offers opportunity for cure with organ preservation in muscle-invasive bladder cancer (MIBC). Treatment response assessment and follow-up are reliant on regular endoscopic evaluation of the retained bladder. In this study we aim to determine the role of diffusion-weighted magnetic resonance imaging (DWI) and apparent diffusion coefficient (ADC) analysis to assess bladder radiotherapy response. MATERIALS AND METHODS Patients with T2-T4aN0-3M0 MIBC suitable for radical radiotherapy were recruited prospectively to an ethics approved protocol. Following transurethral resection of the bladder tumour and prior to any treatment, magnetic resonance imaging including DWI was performed on a 1.5T system using b values of 0, 100, 150, 250, 500, 750 s/mm2. DWI was repeated 3 months after completing radiotherapy. Cystoscopy and tumour site biopsy were undertaken following this. The response was dichotomised into response ( RESULTS Thirty-four patients were evaluated. Response was associated with a significant increase in ΔADC mean compared with poor response at ΔADCall (0.57 × 10-3 mm2/s versus -0.01 × 10-3 mm2/s; P < 0.0001) and ΔADCb100 (0.58 × 10-3 mm2/s versus -0.10 x 10-3 mm2/s; P = 0.007). A 48.50% increase in %ΔADCall mean was seen in response compared with a 1.37% decrease in poor response (P < 0.0001). This corresponded to a %ΔADCb100 mean increase of 50.34% in response versus a 7.36% decrease for poor response (P < 0.0001). Significant area under the curve (AUC) values predictive of radiotherapy response were identified at ΔADC and %ΔADC for ADCall and ADCb100 mean, 10th, 25th, 50th, 75th and 90th percentiles (AUC >0.9, P < 0.01). ΔADCall mean of 0.16 × 10-3 mm2/s and ΔADCb100 mean 0.12 × 10-3 mm2/s predicted radiotherapy response with sensitivity/specificity/positive predictive value/negative predictive value of 92.9%/100.0%/100.0%/75.0% and 89.3%/100.0%/100.0%/66.7%, respectively. CONCLUSIONS Quantitative DWI analysis can successfully provide non-invasive assessment of bladder radiotherapy response. Multicentre validation is required before prospective testing to inform MIBC radiotherapy follow-up schedules and decision making.

Abstract
Air quality is directly associated with the health of society. So, it becomes essential to forecast air pollution, which assumes an imperative part in air pollution warnings and control. A time-series simulation approach was adapted for the forecasting of monthly mean ambient air pollutants (PM2.5, O3, NO2) concentration and Aerosol Optical Depth (AOD) at an urban traffic site (Mathura Road, CSIR-CRRI) in New Delhi, India. Satellite-based aerosol loading (AOD550) retrieved from the Terra MODIS (Collection 6) enhanced Deep Blue (DB) algorithm was used for further analysis. The analysis considered the average monthly mean concentration of air pollutants and AOD between 2012-2017 and, simulates the concentrations of PM2.5, O3, NO2, and AOD for the same period and then forecasts air quality for the years 2020-2023. The forecasted results were validated with 24 months of in-situ and satellite data from 2018-to and 2019. In the year 2020, observed and simulated results are in lower agreement due to the shutdown of anthropogenic activities to combat pandemic situations. Otherwise, modeled and forecasted results are in good harmony with the in-situ and satellite observations. The results also signify that the time series Autoregressive Integrated Moving Average (ARIMA) modeling approach can be an effective and simple tool for air pollution simulation and future forecast. The results are evocative concerning the forecast of near future aerosol loading information and will also be profound to address the problems.

Abstract
The application of QSAR along with other in silico tools like molecular docking, and molecular dynamics provide a lot of promise for finding new treatments for life-threatening diseases like Type 2 diabetes mellitus (T2DM). The present study is an attempt to develop Monte Carlo algorithm-based QSAR models using freely available CORAL software. The experimental data on the α-amylase inhibition by a series of benzothiazole-linked hydrazone/2,5-disubstituted-1,3,4-oxadiazole hybrids were selected as endpoint for the model generation. Initially, a total of eight QSAR models were built using correlation intensity index (CII) as a criterion of predictive potential. The model developed from split 6 using CII was the most reliable because of the highest numerical value of the determination coefficient of the validation set (r2VAL = 0.8739). The important structural fragments responsible for altering the endpoint were also extracted from the best-built model. With the goal of improved prediction quality and lower prediction errors, the validated models were used to build consensus models. Molecular docking was used to know the binding mode and pose of the selected derivatives. Further, to get insight into their metabolism by living beings, ADME studies were investigated using internet freeware, SwissADME.

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO's and Advanced Virgo's Third Observing Run. PHYSICAL REVIEW LETTERS 2022; 129:061104. [PMID: 36018635 DOI: 10.1103/physrevlett.129.061104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 03/18/2022] [Accepted: 06/07/2022] [Indexed: 06/15/2023]
Abstract
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 M_{⊙} and 1.0 M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14 yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200] Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2 M_{⊙}<m_{PBH}<1.0 M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1 M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Abstract
DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 × 6 × 6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.

Abstract
Abstract
Study question
What is cut-off value for peripheral and uterine natural killer (pNK, uNK) cells and any correlation between them in fertile and RIF women?
Summary answer
Cut-off values were 7% for uNK and 11.6% for pNK in fertile controls. No significant correlation observed among fertile and infertile women with RIF.
What is known already
Association of uNK and pNK cells with infertility is debatable. It is not clear whether measuring NK cell levels in RIF has a role. pNk cell levels however has been used in various studies to guide the need of immunotherapy in RIF women. Definition of normal range of uNK cell numbers has also not been stated clearly because of lack of standardised protocol. Literature reveals the cut off values for pNk cells to be 12% or 18% and for uNK cells between 5-12.9%. Correlation between uNK and pNK cells in fertile or RIF women has not been studied earlier.
Study design, size, duration
A prospective study was conducted at ART Centre, Department of Obstetrics and Gynecology at tertiary care institute during a period from January 2019 to January 2021. Thirty women with RIF and fifty fertile controls with age <35 years having regular menstrual cycles and no hormonal treatment in last 3 months were enrolled in the study for uNK and pNK cell testing. The permission was obtained from the Institute Ethics Committee.
Participants/materials, setting, methods
Subjects included women with RIF with age 20-35 years, tubal and unexplained factors, normal ovarian reserve, normal karyotype and normal uterine cavity. In both subjects and controls, midluteal endometrial biopsy sample was taken for Immunohistochemistry staining of CD 56+ cells to determine uNK cells. Peripheral venous blood was also obtained at the time of biopsy for flow cytometry in peripheral blood mononuclear cells to determine pNK cells. Cut off values were derived from fertile controls.
Main results and the role of chance
The mean age and BMI were comparable between fertile control and study group(29.45±3.3 vs 31.17±3.3 years, 22.97±1.89 vs 23.21±2.2 kg/m2; p-value >0.05). The control group had median value of 7% for uNK cell levels and 11.6% for pNK cell levels. In RIF subjects, the median value for uNK cells was 13.5% and even though higher compared to controls it was not statistically significant(p-value >0.05) . The median pNK values were comparable among controls and RIF group (11.6% vs. 12%). All RIF subjects did not have elevated NK cell levels. 18 (60%) subjects had elevated uNK cell levels (more than 7%) whereas 40% had below the reference value. pNK cells were also elevated in only 53.3% of subject population. There was positive correlation found between uNK and pNK cell levels in RIF subjects, however it was not statistically significant (r 0.312, p-value 0.09). In fertile controls, there was insignificant negative correlation between uNK and pNK cell levels (r -0.231, p-value 0.33).
Limitations, reasons for caution
The small sample size is the foremost limitation of study.
Wider implications of the findings
uNK cell testing may be worthwhile in women with unexplained RIF so as to guide immunotherapy to improve pregnancy outcomes. As no significant correlation has been found between pNK and uNK cells in fertile and RIF women, pNK cell testing in RIF women may be done with caution.

Abstract
The importance of selecting appropriate air pollution monitoring sites in a city is vital for accurately reporting air quality, enhancing the quality of high-resolution modelling and informing policy to implement measures to deliver cleaner air in the urban environment. COVID-19 restrictions impacted air quality in urban centres worldwide as reduced mobility led to changes in traffic-related air pollution (TRAP). As such, it offered a unique dataset to examine the spatial and temporal variations in air quality between monitoring stations in Dublin, Ireland. Firstly, an analysis of mobility data showed reductions across almost all sectors after COVID-19 restrictions came into place, which was expected to lower TRAP. In addition, similar changes in air quality were evident to other cities around the world: reductions in fine particulate matter (PM2.5) and nitrogen dioxide (NO2) concentrations and an increase in ozone (O3) concentrations. Average daily and diurnal concentrations for these three pollutants presented more statistically significant spatial and temporal changes during COVID-19 restrictions at monitoring sites with urban or traffic classifications than suburban background sites. Furthermore, substantial reductions in the range of average hourly pollutant concentrations were observed, 79% for PM2.5 and 75% for NO2, with a modest 24% reduction for O3. Correlation analysis of air pollution between monitoring sites and years demonstrated an improvement in the R2 for NO2 concentrations only, suggesting that spatiotemporal homogeneity was most notable for this TRAP due to mobility restrictions during COVID-19. The spatiotemporal representativeness of monitoring stations across the city will change with greener transport, and air quality during COVID-19 can provide a benchmark to support the introduction of new policies for cleaner air.

[PMID: 35749840 DOI: 10.1016/j.bmc.2022.116886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 06/10/2022] [Accepted: 06/14/2022] [Indexed: 11/29/2022]
Abstract
Low molecular weight branched polyethylenimine (LMW bPEIs 1.8 kDa) have received considerable attention for the fabrication of nucleic acid carriers due to their biocompatible and non-toxic nature. However, due to the inadequate nucleic acid complexation ability and transportation across the cell membrane, these show poor transfection efficacy, limiting their clinical applications. Therefore, to overcome these challenges, in this study, we have grafted bPEI 1.8 kDa with a disulfide bond containing hydrophobic moiety, 3-(2-pyridyldithio) propionic acid (PDPA), via amide linkages through EDC/NHS-mediated coupling to obtain N-[3-(2-pyridyldithio)] propionoyl polyethylenimine (PDPP) conjugates. The best formulation for nucleic acid transfection was evaluated after preparing a series of PDPP conjugates by varying the amount of PDPA. In an aqueous environment, these PDPP conjugates self-assembled to form spherical shaped core-shell PDPP nanostructures with size ranging from ∼188-307 nm and zeta-potential from ∼ +3 to +19 mV. The positively charged surface of the core-shell nanocomposites helps in the binding of plasmid DNA (pDNA), its transportation inside the cell, and protection against enzymes. Evaluation of PDPP/pDNA complexes on mammalian cells revealed that all these complexes showed significantly improved transfection efficacy without hampering cytocompatibility. Amongst all, the pDNA complex of PDPP-2 exhibited the best transfection efficiency (i.e. >6-fold) in comparison to pDNA complex of the native bPEI. The nanocomposites exhibited the redox responsive behavior advantageous for therapeutic delivery to the tumor cells. The core of the nanostructures facilitate the encapsulation of a hydrophobic model drug, ornidazole. In vitro drug release analysis showed a faster release rate in response to a reductant mimicking the cellular environment. Altogether, these nanostructures have great potential to co-deliver both drug and gene simultaneously in response to tumor cell reductive microenvironment in vitro and could be used as the next-generation delivery system.

Abstract
109 Background: Early serious illness conversations (SICs) between oncology clinicians and patients are associated with improved mood, quality of life, and quality of end-of-life (EOL) care. Yet, most patients with cancer die without a documented SIC. We report on pre-specified 40-week SIC and EOL outcomes from a stepped-wedge randomized clinical trial (NCT03984773) testing the impact of clinician-directed behavioral nudges to prompt SICs among patients with cancer at high risk of mortality based on a machine learning algorithm. Methods: Our sample consisted of patients with cancer receiving care at one of 9 tertiary or community-based medical oncology clinics between June 2019 and April 2020. We identified high-risk patients using a prospectively validated electronic health record machine learning algorithm to predict 6-month mortality. The intervention consisted of: (1) Weekly emails comparing individual oncologists’ SIC rate relative to peers; (2) Weekly lists of forthcoming encounters with high-risk patients; and (3) Opt-out text messages to prompt SICs before high-risk patient encounters. Clinics were randomized in stepped-wedge fashion to receive the intervention in 4-week intervals through week 16, when all clinics received the intervention. Patients were followed through week 40. The primary outcome was SIC rates for all and high-risk patients. EOL outcomes among decedents were based on ASCO/NQF guidelines and included death in the hospital, intensive care unit admission within 30 days of death, receipt of systemic therapy within 14 days of death, hospice enrollment prior to death, and hospice length of stay. Intention-to-treat analyses were adjusted for clinic and wedge fixed effects and clustered at the oncologist-level. Results: The sample consisted of 20,506 patients and 41,021 encounters. 1,324 (6.5%) patients died by the end of follow-up. Among high-risk patients, the unadjusted SIC rate was 3.4% (59/1754) in the control period and 13.5% (510/3765) in the intervention period and remained >12% throughout follow-up. In adjusted analyses, the intervention was associated with an increase in SICs (adjusted odds ratio 2.09, 95% CI 1.53-2.87, p<0.001) and a decrease in systemic therapy at the end of life, relative to control (6.8% [72/1066]) vs 9.3% [24/258], adjusted odds ratio 0.27, 95% CI 0.12-0.63, p=0.002). There were no differences between control and intervention patients in hospice enrollment or length of stay, inpatient death, or EOL ICU utilization. Conclusions: In this randomized trial, a machine learning-based behavioral intervention led to a sustained increase in serious illness communication and reduction in EOL systemic therapy among outpatients with cancer. Machine learning and behavioral nudges can lead to long-lasting improvements in cancer care delivery. Clinical trial information: NCT03984773.

Abstract
BackgroundUveitis is a sight threatening disease caused by inflammation of the uveal tract of the eye. Uveitis is a manifestation of many autoimmune conditions and is associated with seronegative axial spondyloarthritis, reactive arthritis, Behçet’s disease, inflammatory bowel disease, and psoriatic arthritis. Acute anterior uveitis is the most common presentation and is most commonly idiopathic or associated with the HLA-B27 gene (around 20% of cases). Studies have shown that anterior uveitis frequently recurs in patients after it has previously remitted. (1) Patients suffering from autoimmune conditions are frequently prescribed immunosuppressant drugs to control their illness, thus leaving them more susceptible to bacterial and viral illnesses including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Previous studies have shown that some patients suffer exacerbation of their autoimmune condition after coronavirus vaccination, including uveitis(2). We aim to evaluate our cohort of patients suffering from autoimmune conditions treated at Leicester Uveitis Service at Leicester Royal Infirmary and explore any proposed link.ObjectivesTo assess if COVID19 vaccination is associated with uveitis flares in immunosuppressed patients.MethodsA retrospective study, to determine if patients diagnosed with autoimmune conditions suffered from uveitis following COVID-19 vaccination. A data collection sheet was used to document demographic and clinical data: age, sex, ethnicity, autoimmune condition, dates of COVID-19 vaccination(s), type of vaccine, medication at the time of vaccine, symptoms of autoimmune recurrence, date of uveitis onset and number of days between uveitis onset and latest vaccine. We used an already existing uveitis database with an active register of 2346 patients, of which 246 were on immunomodulation.ResultsAfter reviewing the first 50 patients on immunosuppression for uveitis, we found a total of 4 patients had a uveitis flare despite tight control previously; 3 are female and 1 male, their median age was 39.5 years. They experienced a recurrence of uveitis in the last 6 months. Of these 4 patients 3 were on synthetic DMARDS (2 mycophenolate mofetil, 1 azathioprine), 1 was on steroids and 1 was on a biological DMARD (adalimumab). 2 of the patients suffered from posterior uveitis and 2 from anterior uveitis. All the 50 patients had been vaccinated against COVID19 however there was no clear record of booster dose.ConclusionOur study showed that of 50 immunosuppressed patients, 4 had a uveitis flare following vaccination. Clinicians need to be aware of uvetis flares in rheumatology patients following vaccination. This is a small retrospective analysis of our cohort however a large observational study on flare of uveitis following COVID-19 primary vaccination and booster vaccination would be useful to get meaningful data.References[1]Grunwald L, Newcomb CW, Daniel E, Kaçmaz RO, Jabs DA, Levy-Clarke GA, Nussenblatt RB, Rosenbaum JT, Suhler EB, Thorne JE, Foster CS, Kempen JH; Systemic Immunosuppressive Therapy for Eye Diseases Cohort Study.

Abstract
BackgroundRLS-0071-101 was a first in human clinical trial to evaluate safety of the peptide RLS-0071 in healthy volunteers in a single ascending dose and multiple ascending dose format. RLS-0071, previously referred to as Peptide Inhibitor of Complement C1 (PIC1) is a dual-targeting peptide being developed for clinical use to moderate humoral and cellular inflammation via inhibition of complement activation and neutrophil effectors including myeloperoxidase (MPO) and Neutrophil extracellular trap formation (NETosis).1,2 Humans that are otherwise asymptomatic are considered at risk for cardiovascular complications if they have a plasma MPO level of > 420 pmol.3 A post hoc analysis of plasma samples from subjects participating in RLS-0071-101 identified an individual with mildly elevated baseline MPO level (142 pmol/L).ObjectivesEvaluate if RLS-0071 dosing would change MPO level or activity in a subject with elevated baseline MPO.MethodsFrozen plasma samples prepared from blood collected by venipunture into K2EDTA tubes (BD) was utilized to determine MPO quantity and activity levels. MPO quantity in the plasma was analyzed using a human MPO ELISA kit (BMS2038INST, Invitrogen) and MPO activity within the plasma was analyzed using a fluorescence-based myeloperoxidase assay kit (K745-100, BioVision).ResultsUpon screening 54 subjects from RLS-0071-101 we identified one individual with a mildly elevated MPO level at baseline, a 21-year-old white female with BMI of 21.7. The subject received 9 intravenous infusions of RLS-0071 each at a dose of 10 mg/kg. Her vital signs and body temperature remained normal throughout the study and the only blood laboratory abnormality were a mildly low plasma protein concentration of Day 2 and Day 4 which was noted both among recipients of the peptide and placebo subjects. Analysis of MPO blood concentrations demonstrated a mildly elevated baseline plasma MPO concentration that decreased after multiple doses of RLS-0071 with partial recovery to baseline 24 hours after cessation of dosing. MPO activity analyzed using a fluorescence-based myeloperoxidase assay kit demonstrated an elevated baseline plasma MPO activity level that decreased after multiple doses of RLS-0071 with partial recovery after 24 hours.ConclusionThese results suggest promise for RLS-0071 to reversibly moderate plasma MPO activity and potentially affect MPO-mediated diseases including acute coronary syndrome (ACS), atheromatous plaque vulnerability and auto immune conditions.4,5,6,7.References[1]Sharp, Julia A., et al. “Peptide inhibitor of complement c1, a novel suppressor of classical pathway activation: mechanistic studies and clinical potential.” Frontiers in immunology 5 (2014): 406.[2]Hair, Pamela S., et al. “Inhibition of myeloperoxidase activity in cystic fibrosis sputum by peptide inhibitor of complement C1 (PIC1).” PLoS One 12.1 (2017): e0170203.[3]Tang WH, Wu Y, Nicholls SJ, Hazen SL.

Abstract
BackgroundThe current study aims to gauge the magnitude of the effect the pandemic has had on Rheumatology training (including the effect on clinical, academic and research training) in India, their physical, mental and social wellbeing during the pandemic and the perceived changes in Rheumatology training and care during the pandemic from the trainee’s viewObjectives1.To asses the Impact of COVID-19 Pandemic on the training of Rheumatology Residents (DM, DNB and Fellows)2.Understand the issues faced by trainees and the extent of affection.MethodsStudy design: We conducted an observational cross-sectional study using an online survey sent to rheumatology trainees in India.Sample: Convenience sampling was used, so the sample size was not calculated.Inclusion and exclusion criteria: Rheumatology trainees from India including DM/DNB residents and fellows with the ability and desire to complete the survey were included.Data collection and instruments: The link to the survey was sent to the rheumatology trainees through social media platforms like WhatsApp, Telegram and email.Statistical analysis: Descriptive statistics were performed by calculating measures of central tendency for quantitative variables and using counts and percentages for qualitative and nominal variables.ResultsA total of 78 trainees from 24 institutes in 12 states participated in the study. Mean age of the participants was 31 with 70% of trainees being male and 30 % females. 56 (70%) participants were DM students, 15 (19%) participants were DNB students, 5 fellowship students and 2 Non- academic Senior Residents. An overwhelming majority of residents (84%) felt COVID-19 Pandemic Negatively impacted their residency and their Physical (65%), Mental(74%) and Social wellbeing (80%). 79% of trainees felt burnt-out due to the pandemic. Majority of trainee felt the pandemic negatively impacted their training with clinical teaching(91%), Clinical examination skill (74%), current(80%) and future(70%) research opportunities suffered during the pandemic. Most residents felt diminution and significant reduction of the overall footfall(99% & 72%) of patients in rheumatology including OPD(100% & 77%) and indoor(99% & 67%) admissions along with academics(85% & 35%), procedures(97% & 66%) and exposure to musculoskeletal ultrasound(96% & 71%). Almost 60% and 40% of trainees had their OPDs and indoor admissions stopped during COVID-19 pandemic of these 20% had their OPDs and Admissions closed for more than 6 months. 85% of the participants had one or the other psychological symptoms with almost half experiencing anxiety(44%), low mood(47%) or lack of sleep(41%); 85% were concerned about their family members being infected and 40% lost a close relative to COVID. 91% of the trainee were posted in COVID-duties 2/3rd of them in ICUs, 50% being posted for 1-3 months and 20% more than 3 months, a quarter of trainees got infected during their duties (COVID and Non-COVID) and though most had asymptomatic to mild COVID, 15% still had moderate to severe COVID. Teleconsultation was started by more than half of the respondents after COVID related lockdowns with greater than half not being happy with teleconsultations.ConclusionThe COVID-19 Pandemic has completely altered the status quo for rheumatology trainees and has affected their physical, social and mental wellbeing. Academic and clinical training has reduced, Current and future Research has become difficult, disruptions in OPDs and Admissions, recurrent COVID postings and reduction in patient footfall, Procedures and MSK-US have been detrimental to trainees.References[1]Chandwar K, Dixit J, Kishor K, Ekbote D,Dogga P.

Abstract
BackgroundSystemic lupus erythematosus (SLE) has been associated with more than 100 genetic loci. This parallels positively to the clinical diversity that is reflected by the classification of SLE.ObjectivesWe aimed to investigate associations between disease manifestations of SLE and risk gene variants relevant to Danish subjects of European ancestry.MethodsWe included 427 SLE patients of European ancestry similar to previous reports.[1] We also included 89,699 controls from the Danish Blood Donor Study Genomic Cohort. SLE risk loci in this population were identified by genome-wide association methodology and hereafter correlated to cumulative occurrence of SLE classification items.ResultsFourteen variants mapped to the following genes: NCF2, STAT4, TNPO3/TPI1P2, IRF5, and ITGAM, were significantly associated (p<5E-8) with SLE.The five lead variants were associated (p<0.05) with the following manifestations; NCF2: proteinuria and anti-phospholipid antibodies, STAT4: arthritis, serositis, neurologic disorder, lymphopenia, and anti-Smith antibodies, IRF5: seizures and proteinuria, TNPO3: proteinuria, and ITGAM: photosensitivity (Table 2).ConclusionOur findings support the future use of select, relevant genetic markers in predicting various SLE phenotypes.References[1]Leffers HCB, Troldborg A, Voss A, et al.

Abstract
BackgroundVaccination is one of the most significant public health achievements; however, the success has been marred with vaccine hesitancy. The reasons for vaccine hesitancy are neither singular nor straightforward and arise from a complex interplay between scientific, religious and political beliefs. This study aims to understand the possible reasons for vaccine hesitancy in patients with autoimmune rheumatic diseases and the effectiveness of Specialist counselling on vaccine-hesitant patients willingness to take the vaccine.Objectives1. To assess causes of Vaccine hesitancy against COVID-19 vaccines in patients with autoimmune rheumatic diseases.2. To study the effect of specialist counselling on vaccine-hesitant patients willingness to take vaccine.MethodsStudy design: We conducted an observational survey-based in person cross-sectional study. Patients attending a tertiary care hospital’s outpatient department were asked about their vaccination status. Those unvaccinated were asked reasons for vaccine hesitancy The vaccine-hesitant patients were counselled by the treating rheumatologist and asked regarding their willingness to take the vaccine after the counselling. The patient responses were recorded.Sample: Convenience sampling was used, so the sample size was not calculated.Inclusion and exclusion criteria: All adults(>18yrs) with AIRD coming to the rheumatology OPD. Those vaccinated, recently infected(within 6 weeks), and non-AIRD patients were excluded.Data collection: The questionnaire included patients’ demographic details, Diagnosis, medication details, and response to the reason for vaccine hesitancy.Statistical analysis: Descriptive statistics were performed by calculating measures of central tendency for quantitative variables and using counts and percentages for qualitative and nominal variables.ResultsA total of 322 patients participated in the study with a mean age of 40 years(18-76), with 73%(234) females and 27%(88) males. Most patients had Rheumatoid Arthritis(40%) followed by SPA (27%), SLE(13%) and others and may were on immunosuppressive medications(95%). A significant proportion of patients(60%) had more than one reason for vaccine hesitancy. Almost 60% of the respondents feared their disease might flare post-vaccination, while almost half(44.4%) were hesitant to take the vaccine due to the fear of vaccine side effects and more than one third (35%) feared vaccine may not be effective on them as they were on immunosuppressive medications. Other major causes of vaccine hesitancy were the inability to get a chance to get vaccinated (18%), doubts about vaccine efficacy (15%), and fear of injections (10%).Most patients(91%) were willing to take the vaccine after specialist counselling and only 28 of the 322 (9%) were unwilling even after specialist counselling.ConclusionVaccine hesitancy can be multifactorial. Major reasons for vaccine hesitancy in patients with autoimmune rheumatic diseases were fear of flare of disease post-vaccination, fear of vaccine side effects and doubts whether the vaccine would work in patients taking immunosuppressive medications. Most patients were willing to take vaccine after counselling by a rheumatologist.Disclosure of InterestsNone declared

Abstract
PURPOSE Serious Illness Conversations (SICs) are structured conversations between clinicians and patients about prognosis, treatment goals, and end-of-life preferences. Although behavioral interventions may prompt earlier or more frequent SICs, their impact on the quality of SICs is unclear. METHODS This was a secondary analysis of a randomized clinical trial (NCT03984773) among 78 clinicians and 14,607 patients with cancer testing the impact of an automated mortality prediction with behavioral nudges to clinicians to prompt more SICs. We analyzed 318 randomly selected SICs matched 1:1 by clinicians (159 control and 159 intervention) to compare the quality of intervention vs. control conversations using a validated codebook. Comprehensiveness of SIC documentation was used as a measure of quality, with higher integer numbers of documented conversation domains corresponding to higher quality conversations. A conversation was classified as high-quality if its score was ≥ 8 of a maximum of 10. Using a noninferiority design, mixed effects regression models with clinician-level random effects were used to assess SIC quality in intervention vs. control groups, concluding noninferiority if the adjusted odds ratio (aOR) was not significantly < 0.9. RESULTS Baseline characteristics of the control and intervention groups were similar. Intervention SICs were noninferior to control conversations (aOR 0.99; 95% CI, 0.91 to 1.09). The intervention increased the likelihood of addressing patient-clinician relationship (aOR = 1.99; 95% CI, 1.23 to 3.27; P < .01) and decreased the likelihood of addressing family involvement (aOR = 0.56; 95% CI, 0.34 to 0.90; P < .05). CONCLUSION A behavioral intervention that increased SIC frequency did not decrease their quality. Behavioral prompts may increase SIC frequency without sacrificing quality.

Abstract
Purpose Severe COVID-19 ARDS related end stage lung fibrosis with irreversible changes is a newer indication for lung transplantation with acceptable survival rate. Airway complication post lung transplant is a major source of morbidity and mortality with incidence as high as 25 to 49 percent. Patients with end stage COVID-19 fibrosis are likely to be clinically deconditioned with long duration of extracorporeal oxygenator (ECMO) support, high burden of sepsis and prolonged respiratory support which may affect the airways post lung transplantation. Methods This is a retrospective observational study after obtaining institutional ethical clearance. We reviewed electronic medical data of patients who underwent lung transplantation for post COVID-19 ARDS related fibrosis. We evaluated the incidence and type of airway complications and the various therapeutic interventions applied for its management. Results Between May 2020 and September 2021 our centre performed 23 bilateral lung transplants for end stage COVID-19 ARDS related fibrosis. 22 patients were on ECMO support with mean duration of 50.9 days before transplantation. All patients underwent lung transplantation with central Veno-Arterial ECMO support with mean organ ischaemia time of 360±154 minutes. The incidence of airway complication in our study group was 56%. We observed anastomotic narrowing in 3(13%), distal airway narrowing in 4(17%) and sloughing/coating of anastomotic site in 5(22%) patients. Nonspecific inflammatory polypi around the bronchial anastomotic site were noticed in 4(17%) and mild airway anastomotic dehiscence in 2 subjects. 8(34%) patients required serial bronchoscopy and balloon dilatation; 2 among them mandated additional cautery usage. 2 cases underwent polypectomy, further 4 subjects needed bronchial stent placement. 5 (21%) recipients were discharged with Tracheostomy while rest were successfully decannulated in the ward. Conclusion We observed a high incidence of airway complications in post lung transplant for COVID-19 ARDS related fibrosis. Early detection, timely management and serial follow up is of paramount importance in this subset of patients.

Abstract
The discovery of causal structures behind a phenomenon under investigation has been at the heart of scientific inquiry since the beginning. Randomized control trials, the gold standard for causal analysis, may not always be feasible, such as in the domain of climate sciences. In the absence of interventional data, we are forced to depend only on observational data. This study demonstrates the application of one such causal discovery algorithm using a neural network for identifying the drivers of surface ozone variability in Antarctica. The analyses reveal the overarching influence of the stratosphere on the surface ozone variability in Antarctica, buttressed by the southern annular mode and tropospheric wave forcing in mid-latitudes. We find no significant and robust evidence for the influence of tropical teleconnection on the ground-level ozone in Antarctica. As the field of atmospheric science is now replete with a massive stock of observational data, both satellite and ground-based, this tool for automated causal structure discovery might prove to be invaluable for scientific investigation and flawless decision making.

Abstract
OBJECTIVES The Serious Illness Care Programme (SICP) is a multicomponent evidence-based intervention that improves communication about patients' values and goals in serious illness. We aim to characterise implementation strategies for programme delivery and the contextual factors that influence implementation in three 'real-world' health system SICP initiatives. METHODS We employed a qualitative thematic framework analysis of field notes collected during the first 1.5 years of implementation and a fidelity survey. RESULTS Analysis revealed empiric evidence about implementation and institutional context. All teams successfully implemented clinician training and an electronic health record (EHR) template for documentation of serious illness conversations. When training was used as the primary strategy to engage clinicians, however, clinician receptivity to the programme and adoption of conversations remained limited due to clinical culture-related barriers (eg, clinicians' attitudes, motivations and practice environment). Visible leadership involvement, champion facilitation and automated EHR-based data feedback on documented conversations appeared to improve adoption. Implementing these strategies depended on contextual factors, including leadership support at the specialty level, champion resources and capacity, and EHR capabilities. CONCLUSIONS Health systems need multifaceted implementation strategies to move beyond the limited impact of clinician training in driving improvement in serious illness conversations. These include EHR-based data feedback, involvement of specialty leaders to message the programme and align incentives, and local champions to problem-solve frontline challenges longitudinally. Implementation of these strategies depended on a favourable institutional context. Greater attention to the influence of contextual factors and implementation strategies may enable sustained improvements in serious illness conversations at scale.

Abstract
INTRODUCTION Integrating palliative care (PC) early in the illness course for patients with serious cancers improves their outcomes and is recommended by national organisations such as the American Society of Clinical Oncology. However, monthly visits with PC clinicians from the time of diagnosis can be challenging to implement due to the lack of specialty-trained PC clinicians and resources. Therefore, we developed a stepped care model to triage PC service based on patients' needs. METHODS AND ANALYSIS We are conducting a non-blinded, randomised trial to evaluate the non-inferiority of a stepped PC model compared with an early integrated PC model for improving patients' quality of life (QOL) at 24 weeks (primary outcome). Patients assigned to early integrated PC meet with PC every 4 weeks throughout their illness. Patients assigned to stepped PC have PC visits only at clinically significant points in their illness (eg, cancer progression) unless their QOL decreases, at which time they are 'stepped up' and meet with PC every 4 weeks throughout the remainder of their illness. Secondary aims include assessing whether stepped PC is non-inferior to early integrated PC regarding patient-clinician communication about end of life care and length of stay on hospice as well as comparing resource utilisation. Patients are recruited from the Massachusetts General Hospital Cancer Center, Boston, Massachusetts; Duke Cancer Center, Durham, North Carolina and University of Pennsylvania Abramson Cancer Center, Philadelphia, Pennsylvania. The target sample size is 510 patients. ETHICS AND DISSEMINATION The study is funded by the National Cancer Institute, approved by the Dana-Farber/Harvard Cancer Center Institutional Review Board and will be reported in accordance with the Consolidated Standards of Reporting Trials statement. We will disseminate results through professional society meetings, peer-reviewed publications and presentations to patient organisations. TRIAL REGISTRATION NUMBER NCT03337399.

Abstract
There are several treatment options for localized prostate cancer with very similar outcome but vary in terms of technique and side effect profiles and risks. Considering the potential difficulty in choosing the best treatment, a patient decision aid (PDA) is used to help patients in their decision-making process. However, the use and applicability of PDA in a country in Asia Pacific region like Malaysia is still unknown. This study aims to evaluate the effectiveness of a PDA modified to the local context in improving patients' knowledge, decisional conflict, and preparation for decision making among men with localized prostate cancer. Sixty patients with localized prostate cancer were randomly assigned to control and intervention groups. A self-administered questionnaire, which evaluate the knowledge on prostate cancer (23 items), decisional conflict (10 items) and preparation for decision-making (10 items), was given to all participants at pre- and post-intervention. Data were analyzed using independent T test and paired T test. The intervention group showed significant improvement in knowledge (p = 0.02) and decisional conflict (p = 0.01) from baseline. However, when compared between the control and intervention groups, there were no significant differences at baseline and post-intervention on knowledge, decisional conflict and preparation for decision-making. A PDA on treatment options of localized prostate cancer modified to the local context in an Asia Pacific country improved patients' knowledge and decisional conflict but did not have significant impact on the preparation for decision-making. The study was also registered under the Australian New Zealand Clinical Trials Registry (ANZCTR), ACTRN12614000668606 registered on 25/06/2014.

Abstract
Global QSAR modelling was performed to predict the pIC50 values of 233 diverse heterocyclic compounds as BTK inhibitors with the Monte Carlo algorithm of CORAL software using the DCW hybrid descriptors extracted from SMILES notations of molecules. The dataset of 233 BTK inhibitors was randomly split into training, invisible training, calibration and validation sets. The index of ideality of correlation was also applied to build and judge the predictability of the QSAR models. Eight global QSAR models based on the hybrid optimal descriptor using two target functions, i.e. TF1 (WIIC = 0) and TF2 (WIIC = 0.2) have been constructed. The statistical parameters of QSAR models computed by TF2 are more reliable and robust and were used to predict the pIC50 values. The model constructed for split 4 via TF2 is regarded as the best model and the numerical values of r2Train, r2Valid, Q2Train and Q2Valid are equal to 0.7981, 0.7429, 0.7898 and 0.6784, respectively. By internal and external validation techniques, the predictability and reliability of the designed models have been assessed. The structural attributes responsible for the increase and decrease of pIC50 of BTK inhibitors were also identified.

Abstract
BACKGROUND The dural fold between anterior and middle clinoid processes on mineralisation leads to the formation of caroticoclinoid foramen (CCF). Different morphology of this foramen presents with different clinical features. The present study reports the frequency of CCF in the population of Bihar, while providing an account of assimilated information from previous literature regarding the association of caroticoclinoid ligament ossification with age and human genetics. MATERIALS AND METHODS The study was conducted on 100 adult dry human skulls of unknown age and sex, and 50 lateral view radiographs of the head. RESULTS Of the 100 dry skull bones, 9 presented with different forms of CCF. Bilateral complete foramina were noticed in 2 (2%) skull bones, while the incomplete foramina were observed bilaterally in 3 (3%) and unilaterally in 4 (4%) skulls. The lateral view radiograph data (n = 50) presented with a bilateral foramen in one subject and unilateral complete CCF in two different subjects. On measurements of the diameters of the complete CCF the mean values observed were 4.06 mm and 4.51 mm on the right side, while that on the left side were 5.15 mm and 4.14 mm. For the incomplete foramina, the mean values for the vertical diameter were 4.48 mm on the right and 4.19 mm on the left side, respectively. CONCLUSIONS The frequency of CCF in the present study population of Bihar was much lesser than that of previously studied populations. However, the variation in frequency of different morphological types of CCF was observed to be the same across populations. The variations in CCF's metric data could help in predicting the morphological changes it causes to the clinoidal segment of the internal carotid artery, as well as in distinguishing its varieties.

Abstract
The commercial demand for food products and dietary supplements has increased drastically in the last few decades. The packed food products and nutritional supplements have made a profound impact on the modern human lifestyle. Since ancient times, storage and long-term use of food products remain a significant challenge for humans. There are different parameters for the evaluation of food products and dietary supplements broadly categorized as quality control and quality assurance. On an average million tons of food, materials get spoiled daily worldwide due to lack of storage and transportation point out packaging systems inequalities. To ensure the quality of packed food products and nutritional supplements among available measures, packaging remained an important event and had been refined from time to time to provide a standard. Over a period, the packaging industry has evolved using modern technology from the conventional methods of new generation packaging, including glass, wood, and paper to most new biodegradable materials. The ancient pattern of packaging; manual packaging has been taken over by an automated system of packing, resulting in enhanced output with minimal chance of damage to valuable products for humanity. The article will emphasize new insights into current packaging system not only provide the quality of these products but also in aiming new heights beyond conventional technologies and consumer opinions. In the present study, we have given more emphasis on novel methods of packaging, the packaging materials, quality of packed products, and their impacts of food products on the environment.

Abstract
Phosphodiesterase 5 (PDE5) falls under a broad category of metallohydrolase enzymes responsible for the catalysis of the phosphodiesterase bond, and thus it can terminate the action of cyclic guanosine monophosphate (cGMP). Overexpression of this enzyme leads to development of a number of pathological conditions. Thus, targeting the enzyme to develop inhibitors could be useful for the treatment of erectile dysfunction as well as pulmonary hypertension. In the current study, several molecular modelling techniques were utilized including Bayesian classification, single tree and forest tree recursive partitioning, and genetic function approximation to identify crucial structural fingerprints important for optimization of tri-substituted pyrazoline derivatives as PDE5 inhibitors. Later, various machine learning models were also developed that could be utilized to predict and screen PDE5 inhibitors in the future.

Abstract
BACKGROUND Most patients with advanced melanomas relapse after checkpoint blockade therapy. Thus, immunotherapies are needed that can be applied safely early, in the adjuvant setting. Seviprotimut-L is a vaccine containing human melanoma antigens, plus alum. To assess the efficacy of seviprotimut-L, the Melanoma Antigen Vaccine Immunotherapy Study (MAVIS) was initiated as a three-part multicenter, double-blind, placebo-controlled phase III trial. Results from part B1 are reported here. METHODS Patients with AJCC V.7 stage IIB-III cutaneous melanoma after resection were randomized 2:1, with stage stratification (IIB/C, IIIA, IIIB/C), to seviprotimut-L 40 mcg or placebo. Recurrence-free survival (RFS) was the primary endpoint. For an hypothesized HR of 0.625, one-sided alpha of 0.10, and power 80%, target enrollment was 325 patients. RESULTS For randomized patients (n=347), arms were well-balanced, and treatment-emergent adverse events were similar for seviprotimut-L and placebo. For the primary intent-to-treat endpoint of RFS, the estimated HR was 0.881 (95% CI: 0.629 to 1.233), with stratified logrank p=0.46. However, estimated HRs were not uniform over the stage randomized strata, with HRs (95% CIs) for stages IIB/IIC, IIIA, IIIB/IIIC of 0.67 (95% CI: 0.37 to 1.19), 0.72 (95% CI: 0.35 to 1.50), and 1.19 (95% CI: 0.72 to 1.97), respectively. In the stage IIB/IIC stratum, the effect on RFS was greatest for patients <60 years old (HR=0.324 (95% CI: 0.121 to 0.864)) and those with ulcerated primary melanomas (HR=0.493 (95% CI: 0.255 to 0.952)). CONCLUSIONS Seviprotimut-L is very well tolerated. Exploratory efficacy model estimation supports further study in stage IIB/IIC patients, especially younger patients and those with ulcerated melanomas. TRIAL REGISTRATION NUMBER NCT01546571.

Abstract
Simplified molecular-input line-entry system (SMILES) notation and inbuilt Monte Carlo algorithm of CORAL software were employed to construct generative and prediction QSPR models for the analysis of the power conversion efficiency (PCE) of 215 phenothiazine derivatives. The dataset was divided into four splits and each split was further divided into four sets. A hybrid descriptor, a combination of SMILES and hydrogen suppressed graph (HSG), was employed to build reliable and robust QSPR models. The role of the index of ideality of correlation (IIC) was also studied in depth. We performed a comparative study to predict PCE using two target functions (TF1 without IIC and TF2 with IIC). Eight QSPR models were developed and the models developed with TF2 was shown robust and reliable. The QSPR model generated from split 4 was considered a leading model. The different statistical benchmarks were computed for the lead model and these were rtraining set2=0.7784; rinvisible training set2=0.7955; rcalibration set2=0.7738; rvalidation set2=0.7506; Qtraining set2=0.7691; Qinvisible training set2=0.7850; Qcalibration set2=0.7501; Qvalidation set2=0.7085; IICtraining set = 0.8590; IICinvisible training set = 0.8297; IICcalibration set = 0.8796; IICvalidation set = 0.8293, etc. The promoters of increase and decrease of endpoint PCE were also extracted.

Abstract
Alzheimer's disease (AD) is a global health concern owing to its complexity, which often poses a great challenge to the development of therapeutic approaches. No single theory has yet accounted for the various risk factors leading to the pathological and clinical manifestations of dementia-type AD. Therefore, treatment options targeting various molecules involved in the pathogenesis of the disease have been unsuccessful. However, the exploration of various immunotherapeutic avenues revitalizes hope after decades of disappointment. The hallmark of a good immunotherapeutic candidate is not only to remove amyloid plaques but also to slow cognitive decline. In line with this, both active and passive immunotherapy have shown success and limitations. Recent approval of aducanumab for the treatment of AD demonstrates how close passive immunotherapy is to being successful. However, several major bottlenecks still need to be resolved. This review outlines recent successes and challenges in the pursuit of an AD vaccine.
