Abstract
In the present work, we synthesized a small library of 2-phenylindolizine acetamide derivatives 7a-i and studied their biological activity. The synthesis was accomplished starting with easily available starting material phenacyl bromide 1 proceeding through the key intermediate 6-methyl-7-nitro-2-phenylindolizine 4. All the compounds 7a-i were characterized using spectroscopy viz., 1H NMR, 13C NMR, FTIR, and mass spectrometry. Interestingly, 2-phenylindolizine scaffolds 7c, 7f and 7g revealed a remarkable antibacterial activity against relevant organisms S. aureus, E. coli, S. pneumoniae, P. aeruginosa. The target compounds 7e and 7h showed excellent anticancer activity against Colo-205 and MDA-MB-231 cell lines with IC50 values of 68.62, 62.91, 54.23 and 46.34 µM respectively. Additionally, all the 2-phenylindolizine acetamide derivatives 7a-i were subjected to molecular docking prediction by Autodock 4.2. Compounds 7a, 7f and 7c exhibited very good hydrogen bonding amino acid interactions Asp83 (2.23 Å), Asp83 (2.08 Å), His74 (2.05 Å), His76 (1.71 Å), Ser80 (1.05 Å) with active site of Topoisomerase-IV from S. pneumoniae (4KPE). Further, the compounds 7a-i have revealed acceptable ranges for drug-likeliness properties upon evaluation using SwissADME for ADMET and physiochemical properties.

Abstract
INTRODUCTION This study aimed to describe the composition of the current general surgical consultant body in England and Wales and quantify levels of inequality within it as well as describe future workforce challenges. METHODS This is an observational study of all general surgical departments in England and Wales. Consultant general surgeons were identified and data regarding their gender, country of undergraduate medical education, subspecialty and private practice were recorded. RESULTS Of the 2,682 consultant general surgeons in England and Wales identified for this study, just 17% are women, with gender inequality most marked in university teaching hospitals and among certain subspecialties. Almost 40% of consultants did not obtain their primary undergraduate degree in the United Kingdom and there are considerably fewer surgeons who studied abroad in university teaching hospitals. Over 40% of current general surgical consultants have been qualified for more than three decades and there is no equivalent sized group of younger consultants. CONCLUSIONS There remains considerable gender and racial inequality in the consultant general surgical workforce, with pockets of a lack of diversity within university or teaching hospital surgical departments and some subspecialties. The proportion of surgeons in their fourth decade of clinical practice represents the largest group of current practising consultants, which points towards an impending workforce crisis should senior clinicians seek to reduce activity or consider taking early retirement.

Abstract
1,2,3-Triazole and tetrazole derivatives bearing pyrrolidines are found to exhibit notable biological activity and have become useful scaffolds in medicinal chemistry for application in lead discovery and optimization. We report design, synthesis and molecular docking studies of tetrazolyl-1,2,3-triazole derivatives (7a-i) bearing pyrrolidine moiety and evaluating their anticancer activity against four cancer cell lines viz. Hela, MCF-7, HCT-116 and HepG2. The structures of the new compounds were ascertained by spectral means IR, NMR: 1H &13C and Mass spectrum. From the studies compounds7a and 7i exhibited significant anticancer activity against the Hela cell line with IC50 = 0.32 ± 1.00, 1.80 ± 0.22 μM when compared to reference drug Doxorubicin (IC50 = 2.34 ± 0.11 μM), whereas 7h, 7i, and 7b were found to be active against MCF-7, HCT-116 and HepG2 cell lines with IC50 = 3.20 ± 1.40, 1.38 ± 0.06 and 0.97 ± 0.12 μM respectively. Notably 7a exhibited highest conventional hydrogen bondings TyrA:40, SerA:17, LysA:117, AlaA:146, Tyr218 with 3HB4and SerA:17, LysA:117, AlaA:146, TyrA:40 with 6IBZ and docking energy - 10.85, - 8.21 kcal/mol respectively. These compounds were further evaluated for their ADMET and physicochemical properties by using SwissADME. The results of the in vitro and in silico studies suggest that the tetrazole incorporated pyrrolidine-triazoles may possess the ideal structural requirements for further developing new anticancer agents.

Abstract
PURPOSE/OBJECTIVE(S) As many as 30-50% of patients with locally advanced cervical cancer (LACC) experience recurrence after standard-of-care chemoradiation therapy (CRT), creating a critical need to identify pre-treatment biomarkers of treatment failure. The purpose of this study is to identify whether radiomic features derived from pre-treatment FDG-PET imaging can be used to construct a predictive signature useful for assessing risk of recurrence during treatment planning. MATERIALS/METHODS Standardized uptake values (SUV) were obtained from within the physician-defined metabolic tumor volumes (MTV) delineated on FDG-PET scans acquired for 90 LACC patients at our institution prior to standard of care curative-intent CRT. Clinical outcome data of these patients has a median follow-up time of 85 months. The clinical endpoint was local recurrence within 3 years of treatment. 851 quantitative radiomic features describing intensity, shape, texture and high and low frequency spatial filters of the MTV were extracted for each patient. Low information features, defined by pairwise correlation > 0.85 with another feature or a maximum deviation within 20% of the mean, were discarded, leaving 146 features. Predictive signatures were constructed from features using multiple techniques, including multivariate Cox modelling, a set of machine learning models (random forest (RF), support vector classifier (SVC), ridge regression, LASSO regression, and elastic net regression), and a deep neural network (DNN) classifier. RESULTS The DNN classifier had the best overall performance, predicting a patient's recurrence group with an F1 score of 0.917 ± 0.028 under 5-fold cross-validation. By contrast, the Cox model classifier yielded an F1 score of 0.604 ± 0.085 and the best performing of the alternative machine learning models, elastic net, yielded F1 score of 0.868 ± 0.018. A set of textural features contributed the most to the output of the DNN classifier, including Large Area Low Gray Level Emphasis of the gray level size zone matrix (GLSZM) and coarseness and busyness of the neighboring gray tone difference matrix (NGTDM), reflecting the important role patterns of tumor heterogeneity play in post-treatment recurrence. CONCLUSION In this pilot study, we investigated multiple techniques to construct predictive radiomic signatures for local recurrence in LACC, determining that a DNN classifier is most capable of stratifying patients by risk of early recurrence. Future work will seek to validate this result on additional PET imaging data sets and to integrate radiomic features with gene expression data from matched tumor samples to establish radiogenomic biomarkers for recurrence.

Abstract
PURPOSE/OBJECTIVE(S) Diffuse large B-cell lymphoma (DLBL) has been classified into two distinct molecular subtypes based on their cell of origin- namely germinal center B-cell-like (GCB) and activated B-cell-subtype (ABC) based on Han's algorithm. These two entities are also prognostically distinct. We assessed CT based tumor radiomic features using machine learning classifiers to distinguish the two molecular subtypes. MATERIALS/METHODS One hundred one patients were accrued in the study after institutional ethics committee approval. GCB subtype was diagnosed in 59 while 42 patients were ABC subtype. Lesion with maximum SUV was delineated using a semi-automated segmentation tool (3D slicer) and radiomic features were extracted using Pyradiomics. A total of 1030 features were extracted including Shape features, first, second, third, higher order and wavelet-based features. Recursive feature elimination was used for feature selection and optimal 10 features were selected. Five machine learning (ML) tools were used to build a model to sub- classify the two molecular subtypes. (Table -1) Model performance was assessed using Accuracy, Precision, Recall, F1 score and Area under curve of receiver operating characteristic curve. The models were constructed by two methods.1) A 5-fold internal cross validation strategy & 2) splitting the data into training (70%) and validation set (30%). RESULTS Recursive feature elimination using a random forest algorithm method was used to select 7 radiomic features. These 7 features were then used to build the model using the 5 ML classifiers. Of the five classifiers, Random Forest Classifier (RFC) using a 70:30 training: test strategy was the best performer among all the ML models, with the highest accuracy of 80%, AUC of 0.87, recall(sensitivity), f1score(specificity) & precision (Positive Predictive value; PPV) or precision of 82% respectively. When an internal 5-fold cross validation strategy was used, RFC again performed better than other ML classifiers with an accuracy of 75%, AUC of 0.80, recall of 79%, PPV of 77% and specificity of 79%. CONCLUSION The machine-learning based Radiomics features extracted from pre-treatment CT images can provide a simple and non-invasive method for the prediction of DLBL molecular subtypes with favorable predictive accuracy. The Random Forest Classifier was the most accurate in distinguishing GCB subtype from the ABC subtype.

Abstract
PROBLEM Promotion of a healthy pregnancy is dependent on a coordinated immune response that minimizes inflammation at the maternal-fetal interface. Few studies investigated the effect of fetal sex on proinflammatory biomarkers during pregnancy and whether maternal race could impact this association. We aimed to examine whether fetal sex could, independently of maternal race/ethnicity and the condition of pregnancy (normal vs. complicated), impact inflammatory markers (C-reactive protein [CRP] and interleukin-8 [IL-8] levels) in early and late pregnancy. METHODS OF STUDY This study was a cohort analysis using prospectively collected data from pregnant women who participated in the Vitamin Antenatal Asthma Reduction Trial (VDAART, N = 816). Maternal serum CRP and IL-8 levels were measured in early and late pregnancy (10-18 and 32-38 weeks of gestation, respectively). Five hundred and twenty-eight out of 816 pregnant women who participated in the trial had available CRP and IL-8 measurements at both study time points. We examined the association of fetal sex with early and late CRP and IL-8 levels and their paired sample difference. We further investigated whether maternal race/ethnicity, pregnancy complications (i.e., preeclampsia and gestational diabetes), and early pregnancy body mass index (BMI) could affect the association between these two biomarkers and fetal sex adjusting for potential confounders. For this purpose, we used generalized linear and logistic regression models on log-normalized early and late CRP and IL-8 levels as well as their split at median to form high and low groups. RESULTS Women pregnant with male fetuses (266/528 = 56.5%) had higher CRP levels in early to mid-pregnancy (β = .18: 95% confidence interval [CI]: CI = 0.03-0.32; p = .02). Twenty-seven percent (143/528) of the study subjects were Hispanic. Hispanic African American [AA] women and women of races other than White and AA had higher levels of CRP at early to mid-pregnancy compared with White women (β = .57; 95% CI: 0.17-0.97; p < .01 and β = .27; 95% CI: 0.05-0.48; p = .02, respectively). IL-8 levels were not associated with fetal sex in early and late pregnancy (p's > .05). Other factors such as gestational diabetes and early pregnancy BMI were associated with higher CRP levels and higher CRP and IL-8 levels, respectively. Dichotomizing log-normalized cytokine levels at the median in a sensitivity analysis, women with male fetuses had lower odds of high (above-median) IL-8 levels at early pregnancy. Also, women with races other than AA and White carrying male fetuses had higher odds of having high (above-median) late-pregnancy CRP and early-pregnancy IL-8 levels (adjusted odds ratio [aOR] = 3.80, 95% CI: 0.24-1.23; p = .02 and aOR = 3.57; 95% CI: 0.23-1.03; p = .02, respectively). Of the pregnancy complications, women with gestational diabetes mellitus had a higher paired difference of early and late pregnancy CRP levels (β = .38; 95% CI: 0.09-0.68; p = .01), but no difference in IL-8 levels (p's > .05). No associations between the inflammatory markers and preeclampsia were found. CONCLUSION Fetal sex is associated with CRP in early pregnancy and an association with IL-8 in early pregnancy is implied. Our study further indicates that maternal race/ethnicity could be a contributing factor in the relationship between fetal sex and inflammatory responses during pregnancy. However, the specificity and level of the contribution might vary by type of cytokine, pregnancy stage, and other confounding factors such as BMI that may impact these associations.

Abstract
Background Positioning patients with femur fractures for spinal anesthesia is associated with excruciating pain. Fascia iliaca compartment block has the potential to block all nerves supplying the femur and therefore may provide effective analgesia during positioning these patients for spinal anesthesia. Objective To assess the analgesic efficacy of Fascia iliaca compartment block, during positioning patients with femur fracture for spinal anesthesia. We also assessed the duration of analgesia and the requirement for rescue analgesics in the postoperative period. Method Seventy adult patients with fracture femurs were randomly divided into two equal groups (A and B). Patients in both groups received fentanyl one mcg/kg intravenously, 20 minutes before positioning them for spinal anesthesia. Patients of group B additionally, received ultrasound-guided Fascia iliaca compartment block with 40 ml of 0.25% Ropivacaine, immediately after intravenous fentanyl. Numerical rating score (0-10) was used for the assessment of pain at five, 10, and 20 minutes after the block and immediately after positioning patients for spinal anesthesia. Result Immediately after positioning patients for spinal anesthesia, the numerical rating score of pain was 5.06±1.5 in group A and 2.49±1.2 in group B (p<0.001). The duration of analgesia was 799.7±62.1 minutes in group B and 314.65±118.9 minutes in group A (p<0.001). One (2.8%) patient of group B and 18(51.4%) patients of group A required rescue analgesics within four to twelve hours in the postoperative period (p=0.001). In group A, seven patients were satisfied with the analgesia technique while in group B, 17 were satisfied and eight patients were strongly satisfied (p<0.001). Conclusion Ultrasound-guided Fascia iliaca compartment block is effective in reducing pain during positioning patients with femur fractures for spinal anesthesia. Patients receiving this block had a prolonged duration of analgesia, required lesser analgesics, and were more satisfied in the postoperative period as compared to patients not receiving the block.

Abstract
Silkworms have limited ability to regulate their body temperature; therefore, environmental changes, such as global warming, can adversely affect their viability. Polyamines have shown protection to various organisms against heat stress. This study evaluated the qualitative and quantitative changes in heat-stressed Bombyx mori larvae polyamines. Fifth instar Bombyx mori larvae were divided into two groups; control group, reared at room temperature, i.e., 28 ± 2 °C, and the heat shock group, exposed to 40 °C. Dansylation of the whole worm polyamines and subsequent thin-layer chromatography revealed the presence of components with the same Rf value as dansyl-putrescine, spermidine, and spermine. The dansyl-putrescine, spermidine, and spermine polyamines were identified by mass spectrometric analyses. After heat shock, the thin-layer chromatography of the whole-larvae tissue extracts showed qualitative and quantitative changes in dansylated polyamines. A new polyamine, caldopentamine, was identified, which showed elevated levels in heat-stressed larvae. This polyamine could play a role in helping the larvae tolerate various stress, including thermal stress. No significant changes in silk fiber's economic and mechanical properties were observed in our study. This study indicated that PA, caldopentamine, supplementation could improve heat-stress tolerance in Bombyx mori.

Abstract
BACKGROUND Long noncoding RNAs (lncRNAs) have emerged as novel regulators of macrophage biology and inflammatory cardiovascular diseases. However, studies focused on lncRNAs in human macrophage subtypes, particularly human lncRNAs that are not conserved in rodents, are limited. METHODS Through RNA-sequencing of human monocyte-derived macrophages, we identified suppressor of inflammatory macrophage apoptosis lncRNA (SIMALR). Lipopolysaccharide/IFNγ (interferon γ) stimulated human macrophages were treated with SIMALR antisense oligonucleotides and subjected to RNA-sequencing to investigate the function of SIMALR. Western blots, luciferase assay, and RNA immunoprecipitation were performed to validate function and potential mechanism of SIMALR. RNAscope was performed to identify SIMALR expression in human carotid atherosclerotic plaques. RESULTS RNA-sequencing of human monocyte-derived macrophages identified SIMALR, a human macrophage-specific long intergenic noncoding RNA that is highly induced in lipopolysaccharide/IFNγ-stimulated macrophages. SIMALR knockdown in lipopolysaccharide/IFNγ stimulated THP1 human macrophages induced apoptosis of inflammatory macrophages, as shown by increased protein expression of cleaved PARP (poly[ADP-ribose] polymerase), caspase 9, caspase 3, and Annexin V+. RNA-sequencing of control versus SIMALR knockdown in lipopolysaccharide/IFNγ-stimulated macrophages showed Netrin-1 (NTN1) to be significantly decreased upon SIMALR knockdown. We confirmed that NTN1 knockdown in lipopolysaccharide/IFNγ-stimulated macrophages induced apoptosis. The SIMALR knockdown-induced apoptotic phenotype was rescued by adding recombinant NTN1. NTN1 promoter-luciferase reporter activity was increased in HEK293T (human embryonic kidney 293) cells treated with lentiviral overexpression of SIMALR. NTN1 promoter activity is known to require HIF1α (hypoxia-inducible factor 1 subunit alpha), and our studies suggest that SIMALR may interact with HIF1α to regulate NTN1 transcription, thereby regulating macrophages apoptosis. SIMALR was found to be expressed in macrophages in human carotid atherosclerotic plaques of symptomatic patients. CONCLUSIONS SIMALR is a nonconserved, human macrophage lncRNA expressed in atherosclerosis that suppresses macrophage apoptosis. SIMALR partners with HIF1α (hypoxia-inducible factor 1 subunit alpha) to regulate NTN1, which is a known macrophage survival factor. This work illustrates the importance of interrogating the functions of human lncRNAs and exploring their translational and therapeutic potential in human atherosclerosis.

Abstract
Lesbian, gay, bisexual, transgender, queer, and intersex are at increased risk of getting infected with sexually transmitted infections, suicidal behaviours, and substance and physical abuse. Stigmatization and discriminatory attitudes toward the community have led to disparities while receiving healthcare. In this article, we discuss the condition of healthcare in sexual minorities in Nepal, the major barriers to accessing healthcare facilities, the roles played by nongovernmental organizations, and the possible ways to improve healthcare in the lesbian, gay, bisexual, transgender, queer, and intersex community.

Abstract
OBJECTIVE The determinants of preterm birth remain unknown. Excessive maternal inflammation during pregnancy may play an important role in the pathogenesis of preterm birth. Our objective was to describe the association of prenatal levels of proinflammatory C-reactive protein (CRP) and interleukin-8 (IL-8) with preterm birth in participants of the Vitamin D Antenatal Asthma Reduction Trial. STUDY DESIGN Five hundred and twenty-eight patients with available samples of both first- and third-trimester plasma were included in this analysis. CRP and IL-8 were measured from maternal prenatal samples. We examined the association between prenatal CRP and IL-8 with maternal health characteristics and the outcome of preterm birth. We also described the patterns of change in CRP and IL-8 from first to third trimester and their association with preterm birth. A subgroup analysis comparing only those with a spontaneous preterm birth phenotype to those with term birth was also performed. RESULTS Maternal characteristics including lower educational attainment, higher prepregnancy body mass index, gestational diabetes, lower vitamin D, and an unhealthy diet were associated with elevated levels of prenatal CRP and IL-8. Higher third trimester CRP and an increase in CRP from first to third trimester were associated with an increased odds of preterm birth when compared to lower levels of CRP (adjusted odds ratio [aOR] = 1.49, 95% confidence interval: 1.02, 2.23, p = 0.04) or a decrease in CRP over pregnancy (aOR = 3.06, 95% CI = 1.31,7.55, p = 0.01), after adjusting for potential confounders. These associations were strengthened when comparing only patients with spontaneous preterm birth (n = 22) to those with term births. CONCLUSION Higher levels of the proinflammatory markers CRP and IL-8 are associated with indicators of poor maternal health and preterm birth. Prenatal CRP levels may reflect maternal prenatal health status and serve as a predictor of preterm birth, especially among those with spontaneous preterm birth. KEY POINTS · Elevated prenatal CRP is associated with poor maternal health.. · High prenatal CRP may predict premature birth, especially spontaneous premature birth phenotypes.. · Vitamin D insufficiency may be a modifiable risk factor for prenatal inflammation..

Abstract
BACKGROUND The pathogenesis of childhood asthma is complex, and determinants of risk may begin in utero. OBJECTIVE To describe the association of systemic prenatal inflammation, measured by plasma C-reactive protein (CRP), with childhood asthma, eczema, and allergic rhinitis. METHODS A total of 522 maternal-offspring pairs from the Vitamin D Antenatal Asthma Reduction Trial were included. Prenatal plasma CRP level was measured between 10 and 18 weeks of gestation and between 32 and 38 weeks of gestation. Offspring asthma, eczema, and allergic rhinitis were assessed quarterly between birth and age 6 years. We performed mediation analyses of prenatal CRP on the association between several maternal characteristics and offspring asthma. RESULTS Elevated early and late prenatal CRP and an increase in CRP from early to late pregnancy were associated with asthma by age 6 years (early: adjusted odds ratio [aOR], 1.76, 95% CI, 1.12-2.82, P = .02; late: aOR, 2.45, 95% CI, 1.47-4.18, P < .001; CRP increase: aOR, 2.06, 95% CI, 1.26-3.39, P < .004). Prenatal CRP and childhood asthma associations were strengthened among offspring with atopic asthma (early: aOR, 3.78, 95% CI, 1.49-10.64, P = .008; late: aOR, 4.84, 95% CI, 1.68-15.50, P = .005; CRP increase: aOR, 3.01, 95% CI, 1.06-9.16, P = .04). Early and late prenatal CRP mediated 96% and 86% of the association between maternal prepregnancy body mass index and offspring asthma, respectively. CONCLUSIONS Higher prenatal CRP and an increase in CRP from early to late pregnancy are associated with childhood asthma. Systemic inflammation during pregnancy associated with modifiable maternal characteristics may be an important determinant of childhood asthma risk.

Abstract
Abstract
Aims
To assess whether patients on the elderly care wards at NUH (Nottingham University Hospitals) were appropriately given IV (intravenous) iron for Iron deficiency anaemia (IDA). To improve our practice in the investigation and follow up of patients with IDA.
Method
Data was obtained of patients who had IV iron dispensed from June—September 2019. This totalled 146 patients. Digital medical records and Notis results. Server were reviewed and a spread sheet database compiled with patient demographics, presentation, blood results. Co-morbidities, medication, investigations and follow up.
Results
The average age of the patients receiving IV iron on the elderly care wards was 86 (range 74–106). 89 were female and 57 male. The top presenting complaints were; fall (38%), abdominal symptoms of pain, diarrhoea or vomiting (15%), SOB (12%). 30% of patient were on anti-coagulation and 27% were on an anti-platelet with 2% of patient on both. Mean female Hb was 89 (41–129) and male Hb was 91 (49–117). The data showed that 8 out of 81 female patients were given IV iron despite not being anaemic. In 7.5% of cases ferritin, TSAT, iron and transferrin had not been checked. Ferritin was not checked 16%. 82% of patients had no documentation with regards to the rationale for choosing not to proceed with invasive investigation.
Conclusion
Improvement is needed in the way we manage patients with IDA. This audit highlighted the need for continued review of medications—particularly anti-platelets and anti-coagulants. If there is a weak indication consider the risks and benefits. It is important we discuss and document the consideration or unsuitability of invasive investigations and follow up. A proforma is being written to guide clinicians with regards to the appropriate prescribing of IV iron and to guide investigation and follow up.

Abstract
Many complex disease risk loci map to intergenic regions containing long intergenic noncoding RNAs (lincRNAs). The majority of these is not conserved outside humans, raising the question whether genetically regulated expression of non-conserved and conserved lincRNAs has similar rates of association with complex traits. Here we leveraged data from the Genotype-Tissue Expression (GTEx) project and multiple public genome-wide association study (GWAS) resources. Using an established transcriptome-wide association study (TWAS) tool, FUSION, we interrogated the associations between cis-regulated expression of lincRNAs and multiple cardiometabolic traits. We found that cis-regulated expression of non-conserved lincRNAs had a strikingly similar trend of association with complex cardiometabolic traits as conserved lincRNAs. This finding challenges the conventional notion of conservation that has led to prioritization of conserved loci for functional studies and calls attention to the need to develop comprehensive strategies to study the large number of non-conserved human lincRNAs that may contribute to human disease.

Abstract
Nevus lipomatosus cutaneous superficialis (NLCS) is a rare idiopathic cutaneous hamartoma characterized by ectopic clusters of mature adipose tissues in dermis. It is classified into two types. Classical type presenting as multiple lesions with onset at birth or within third decade of life and solitary type with onset between third to sixth decade of life. Here we present a case of 45 years female with adult onset, asymptomatic, grouped, skin colored, soft sessile growth in zosteriform pattern on left buttock. We here intend to report rare case of classical Nevus Lipomatosus Cutaneous Superficialis.

Abstract
SARS-COV-2, the novel coronavirus and root of global pandemic COVID-19 caused a severe health threat throughout the world. Lack of specific treatments raised an effort to find potential inhibitors for the viral proteins. The recently invented crystal structure of SARS-CoV-2 main protease (Mpro) and its key role in viral replication; non-resemblance to any human protease makes it a perfect target for inhibitor research. This article reports a computer-aided drug design (CADD) approach for the screening of 118 compounds with 16 distinct heterocyclic moieties in comparison with 5 natural products and 7 repurposed drugs. Molecular docking analysis against Mpro protein were performed finding isatin linked with a oxidiazoles (A2 and A4) derivatives to have the best docking scores of -11.22 kcal/mol and -11.15 kcal/mol respectively. Structure-activity relationship studies showed a good comparison with a known active Mpro inhibitor and repurposed drug ebselen with an IC50 value of -0.67 μM. Molecular Dynamics (MD) simulations for 50 ns were performed for A2 and A4 supporting the stability of the two compounds within the binding pocket, largely at the S1, S2 and S4 domains with high binding energy suggesting their suitability as potential inhibitors of Mpro for SARS-CoV-2.

Abstract
Cutaneous tuberculosis classically presents as Lupus vulgaris, scrofuloderma, tuberculosis verrucose cutis and tubercular abscess. Hypersensitivity reaction to the bacilli leads to Lichen scrofulosorum and papulonecrotic tuberculids. At the same time, it can have myriad of clinical presentations, many of which are still undescribed. It is important to regularly update ourselves with these unusual manifestations so as to ensure early treatment and reduction of overall morbidity. In this case series tuberculosis manifesting as rapidly progressing diffuse facial granulomas, sporotrichoid tuberculosis, tuberculosis mimicking squamous cell carcinoma, scrofuloderma as tubercular ulcer, lupus vulgaris with nasal septal perforation, lupus vulgaris resembling furuncle, psoriasis, dermatitis and BT Hansen are described in immunocompetent individuals. These cases highlight the importance of recognition of atypical forms of cutaneous tuberculosis to minimize scarring and dissemination of bacilli.

Abstract
Computer Aided Drug Design approaches have been applied to predict potential inhibitors for two different kinases, namely, cyclin-dependent kinase 2 (CDK2) and Epidermal Growth Factor Receptor (EGFR) which are known to play crucial role in cancer growth. We have designed alkyl and aryl substituted isatin-triazole ligands and performed molecular docking to rank and predict possible binding pockets in CDK2 and EGFR kinases. Best-scoring ligands in the kinase-binding pocket were selected from the docking study and subjected to molecular dynamics simulation. Absolute binding affinities were estimated from the MD trajectories using the MM/PBSA approach. The results suggest that aryl substituted isatin-triazole ligands are better binder to the kinases relative to its alkyl analogue. Furthermore, aryl substituted isatin-triazole ligands prefer binding to EGFR kinases relative to CDK2. The ligand binding pockets of the kinases are primarily hydrophobic in nature. Ligand-kinase binding is favoured by electrostatic and Van der Waals interactions, later being the major contributor. Large estimated negative binding affinities (~ -10 to -25 kcal/mol) indicate that the ligands might inhibit the kinases. Physicochemical property analysis suggests that the proposed ligands could be orally bio-available.

Abstract
PURPOSE To explore the recognition, response and understanding of delirium in families and carers of hospitalised patients. METHODS All adults with delirium admitted to an acute medical unit were included. Delirium was diagnosed by a specialist geriatrician. The responder who sought medical advice for each patient was interviewed using a delirium recognition questionnaire. Vital status was ascertained at four months. RESULTS Sixty patients were included (mean age 85, SD 6.8 years). Reported symptoms included drowsiness and lack of responsiveness, though these were less commonly recognised as being due to delirium. 76% received medical advice within 24 h, although two responders took > 1 week. One-third of responders had never heard of delirium. Delirium knowledge among responders was variable. CONCLUSION Overall awareness and knowledge of delirium was poor. Community delirium education and public health initiatives may improve rapidity of recognition, delirium assessment, and potentially health outcomes.

Abstract
INTRODUCTION Squamous cell carcinoma is the most common variant of anal malignancy. Certain disease-related factors have been established in determining survival. These include tumour size, differentiation and nodal involvement. Other factors such as HIV status, human papillomavirus infection, smoking and socioeconomic disparity may have important roles, however few data are available on the UK population. We aim to correlate social deprivation and survival of anal cancer patients at a tertiary centre. MATERIALS AND METHODS All consecutive cases diagnosed with anal squamous cell carcinoma and treated as per local protocol between July 2010 and April 2017 were included. The pathological and demographical details were collected from a prospectively maintained database. Socioeconomic deprivation was defined for each postcode using the Index of Multiple Deprivation decile compiled by local governments in England. Survival was estimated using Kaplan-Meier analysis and Cox regression was used to investigate the effect of different factors on overall survival. RESULTS A total of 129 patients with anal squamous cell carcinoma over a median follow-up of 43 months were included. Overall survival for the entire patient cohort was 87.7% (95% confidence interval, CI, 82.0-93.7%), 75.5% (95% CI 67.5-84.5%) and 68.9% (95% CI 59.7-79.6%) at one year, three years and five years, respectively. On multivariate analysis, Index of Multiple Deprivation and income do not significantly influence overall survival (p = 0.79, hazard ratio, HR, 1.07; 95% CI 0.61-1.63), (p = 0.99, HR=1.00; 95% CI 0.61-1.63), respectively. Increased risk of death was observed for male sex (p = 0.02, HR=2.80; 95% CI 1.02-5.50) and larger tumour size (p = 0.01, HR=1.64; 95% CI 1.12-2.41). CONCLUSION In contrast to US studies, there is little difference in survival between the least deprived and most deprived groups. We attribute this to equal access to intensity-modulated radiation therapy-based chemoradiotherapy. Thus, a highly effective treatment made available to all mitigates any survival difference between socioeconomic groups.

Abstract
Abstract
Background: There is evidence that increases in germline cancer genetic testing result in higher rates of contralateral prophylactic mastectomy (CPM) in newly diagnosed breast cancer (BC) patients, even among those with negative results. Unlike carriers of BRCA pathogenic variants (PV), the risks of contralateral breast cancer (CBC) and benefits of CPM for women with PV in moderate penetrance genes are not well studied. There is a critical need to determine how to best counsel BC patients about their personal CBC risk and surgical decisions.
Trial design: Newly diagnosed BC patients are randomized 1:1 to quantitative or standard post-genetic test cancer risk counseling methods by genetic counselors. Quantitative counseling includes personalized CBC risk estimates. For patients with a PV in a BC risk gene, CBC risk estimates are calculated via the “ASK2ME” decision tool (https://ask2me.org/). For those without a BC-associated PV, CBC risk estimates are calculated via a validated model “CBCRisk” (https://cbc-predictor-utd.shinyapps.io/CBCRisk/).Standard counseling does not typically include specific CBC risk estimates.Eligibility criteria: All patients over 18 with newly diagnosed invasive or in situ unilateral BC considering genetic testing at Dana-Farber/Brigham and Women’s Cancer Center are eligible. Exclusion criteria include a diagnosis of previous BC, metastatic or bilateral BC, hematologic malignancy, prior or active other malignancy, prior multi-gene panel testing, known medical or surgical contraindication to surgery and/or CPM.Specific aims: The primary aims are to 1) compare changes in patients’ personal CBC risk assessment before/after quantitative versus standard counseling; 2) determine changes in patients’ propensity to choose CPM before/after quantitative versus standard counseling. The secondary aims are to: 1) compare CPM rates; 2) determine concordance between patient and surgeon assessment of CBC risk; 3) evaluate patient genetic testing satisfaction via the Genetic Testing Satisfaction Survey administered post-counseling; 4) measure patient anxiety via the PROMIS Anxiety Survey administered pre- and post-counseling, at 6 months and 2 years; and 5) measure patient decisional regret for both undergoing genetic testing and their surgery choices at 6 months and 2 years; all by quantitative versus standard counseling arms.
Statistical methods: For aim 1, the difference between patients’ reported personal CBC risk and true risk before and after counseling will be determined. True risk will be based on the ASK2ME/CBCRisk estimates. We hypothesize that the difference between the true and estimated risk will be smaller post-counseling, and smaller in the quantitative counseling versus standard arm. Assuming an expected difference of 5% and expected standard deviation of 20%, 199 patients are needed for each arm to achieve 80% power and type I error of 5% (based on a two-sample t-test). For aim 2, to determine propensity to undergo CPM, patient responses will be assigned a numeric value: Very Unlikely (1), Somewhat unlikely (2), Unsure (3), Somewhat likely (4), Very likely (5). For each patient we will then calculate the difference in scores before/after counseling. Our hypothesis is that differences will be greater in the quantitative arm. Assuming an expected difference of 0.8 and expected standard deviation of 3, 175 patients are needed for each arm to achieve 80% power and type I error rate of 5% (based on a two-sample t-test).
Accrual: Recruitment began on June 8, 2020; there are currently 9 of the target 450 patients enrolled.

Abstract
Background Determination of Amniotic Fluid Index (AFI) is an important component of antepartum assessment of all normal pregnancies. Objective To compare the obstetric interventions and neonatal outcomes in term pregnancies with borderline Amniotic Fluid Index versus normal Amniotic Fluid Index. Method This hospital based prospective study was conducted at Tribhuwan University Teaching Hospital over 1 year between 2017 and 2018 in 128 women having uncomplicated term pregnancy admitted in labor ward. Of the 128 women, 64 women had borderline Amniotic Fluid Index (5.1-8 cm) and 64 normal AFI (8.1 - 24 cm). Parameters studied were induction of labor, cesarean section, instrumental delivery, intrapartum abnormal fetal heart rate, meconium staining of liquor, APGAR score at 5 and 7 minutes, birth weight, neonatal intensive care unit (NICU) admission and neonatal death. Data was analyzed using software OpenEpi. Result Statistically significant difference in result was obtained in the two groups in terms of rate of induction of labor (73.4% vs 35.9%, p = 0.0001, OR = 4.9), rate of cesarean section (42.1% vs 28 .1%, p = 0.04, OR = 1.8), tachypnea (50% vs 11.1%, p = 0.01) and low birth weight (9.1% vs 4.5%, p = 0.04). No statistical significance was found in meconium staining of liquor (33% vs 38.3%, p = 0.3) and APGAR score of <7 at 5 minutes (3.1% vs 1.5%, p = 0.06). There were no neonatal intensive care unit admissions and neonatal mortality in any of the babies. Conclusion Detection of amniotic fluid volume at term is important for timely maternal interventions to improve the overall fetal outcome.

Abstract
Abstract
Background and aims
Nearly half of all heart failure patients have heart failure with preserved ejection fraction (HFpEF). Due to differences in pathophysiology of heart failure with preserved and reduced ejection fraction, as well as a paucity of studies, the treatment of hHFpEF remains a challenge.
We aimed to determine the rate of hospital readmission within 30 days of acute or acute on chronic HFpEF and its impact on mortality and health care utilization in the United States. We also focused on patient demographics as well as independent variables affecting readmission.
Methods
We performed a retrospective study using the Agency for Health-care Research and Quality's Health-care Cost and Utilization Project (HCUP), Nationwide Readmission Database (NRD) for the year of 2017 (data on approximately 18 million hospital stays at 2,454 hospitals in the United States). We collected data on hospital readmissions of 60,514 adults who were hospitalized for acute or acute on chronic diastolic heart failure and discharged. The primary outcome was the rate of all-cause readmission within 30 days of discharge. Secondary outcomes were reasons for readmission, readmission mortality rate, and resource use (length of stay, total hospitalization costs and charges). Independent risk factors for readmission were identified using Cox regression analysis.
Results
The 30-day rate of readmission was 21%. Only 1,175 (9.17%) of readmissions were associated with an admitting diagnosis of acute on chronic diastolic heart failure. The most common readmission diagnosis was hypertensive chronic kidney disease with heart failure (1,245; 9.7%). Readmission cases were associated with increased in-hospital mortality compared to index admission (7.9% vs 2.9%, p=0.000). Readmission was associated with a total of 81,997 hospital days. Total health care in-hospital economic burden was $206 million (in costs) and $779 million (in charges). Significant predictors of increased thirty-day readmission were Medicaid insurance (1.15, 1.05–1.27, p=0.004), higher Charlson co-morbidity score (1.08, 1.06–1.09, p=0.000), patient admitted to teaching hospital (1.09, 1.04–1.15, p=0.001) and longer stays in the hospital (1.01, 1.01–1.02, p=0.000). Residence in a small metropolitan (0.91, 0.86–0.97, p=0.003) or micropolitan area (0.83, 0.77–0.90, p=0.000), older age (0.99, 0.993–0.997, p=0.000), female sex (0.91, 0.86–0.95, p=0.000), private (0.85, 0.77–0.93, p=0.000) or no insurance (0.70, 0.53–0.93, p=0.015) were associated with lower odds of readmission. Interestingly discharges to rehabilitation had no effect on re-admission (0.67, 0.28–1.6, p=0.381).
Conclusions
In conclusion patients hospitalized for acute or acute on chronic HFpEF, we found that 21% of patients were readmitted to the hospital within 30 days of discharge. Readmissions were associated with higher mortality and resource utilization. Most readmissions were due to cardiorenal syndrome.

Abstract
Ligand-based pharmacophore modelling and virtual screening along with in vitro screening were performed as a rational strategy for the identification of novel compounds as apoptosis inducers and anticancer agents from the chemical database. Known apoptosis inducers were selected from the literature for generation of pharmacophore models, which were subjected to validation using Receiver operating characteristic (ROC) and Günere-Henry (GH) scoring methods. Based on highest fitness score of 4680.61, ROC value of 0.872 and GH score of 0.758, pharmacophore model-2 was selected as the best model. Model-2 as 3D search query was searched against the IBS database to find novel compounds as hits. Three hits were selected with a QFIT value more than 82 for in vitro screening as apoptosis inducers and anticancer agents. In vitro anticancer activity was performed using resazurin cell variability assay, and apoptosis inducing activity was determined using caspase-3 activation and annexin-FITC assays. One of the retrieved hit, STOCK5S-44056 demonstrated IC50 value of 23.56 µM in cell variability assay, and had EC50 value of 26.95 µM in caspase-3 activation assay. STOCK5S-44056 also indicated late stage induction of apoptosis in annexin assay. The results of in vitro activity revealed that STOCK5S-44056 has a potential to become anticancer agents.

Abstract
The yellow-throated bulbul (YTB) is an endemic passerine restricted to scrub forests along hill slopes with exposed rocky outcrops in the Deccan Peninsula, India. It is found in small, discontinuous populations and is vulnerable to extinction due to ongoing habitat loss and subsequent population decline. To assess the genetic connectivity and past demography, we sequenced 1050 nucleotide base pairs of the mitochondrial control region of 60 individuals that represent distinct populations in the geographic range of the species. We recovered 39 haplotypes defined by 81 variable sites. Haplotype diversity was high with low nucleotide diversity, suggesting rapid population growth from a founder population with a small effective population size. The negative values of Tajima’sDand Fu’sFsand small positive value of Ramos-Onsins and Rozas’R2suggest deviation from neutrality and population expansion. The haplotype network and demographic expansion parameters further suggest historical population expansion. Mismatch analysis statistics and Bayesian skyline plots estimate population expansion during the late Pleistocene. Although the species presently occurs in small, disconnected we found no structuring of the population. Dispersal events are the most likely explanation for the absence of genetic structuring in the YTB population. These results represent important data for the design of a conservation plan for this endemic and globally threatened species.

Abstract
BACKGROUND AND PURPOSE A new transtentorial venous system consisting of medial, intermediate, and lateral tentorial veins, connecting infra- and supratentorial compartments, was recently shown in 2 cadaver dissections and 2 patient scans. We sought to characterize the venous patterns within the tentorium and their relation to measures of skull development in a cohort of healthy adults. MATERIALS AND METHODS We retrospectively reviewed tentorial venous anatomy of the head using CTA/CTV performed for routine care or research purposes in 238 patients. Included studies had adequate contrast opacification of venous structures and a section thickness of ≤2 mm; we excluded cases with space-occupying lesions and vascular pathologies. Tentorial angle, dural sinus configurations, and measures of skull base development were assessed as predictors of tentorial venous anatomy variation via Cramér V association, the binary encoded Pearson correlation, and nearest-point algorithm with the Euclidean distance metric for clustering. RESULTS Tentorial vein development was related to the ringed configuration of the tentorial sinuses (P < .005). There were 3 configurations. Groups 1A and 1B (n = 50/238) had ringed configuration, while group 2 did not (n = 188/238). Group 1A (n = 38/50) had a medialized ringed configuration, and group 1B had a lateralized ringed configuration (n = 12/50). Measurements of skull base development were predictive of these groups. The ringed configuration of group 1 was related to the presence of a split confluens, which correlated with a decreased internal auditory canal-petroclival fissure angle. Configuration 1A was related to the degree of petrous apex pneumatization (P value = .010). CONCLUSIONS Variations in the transtentorial venous system directly correlate with cranial development.

Abstract
Common Variable Immunodeficiency (CVID) is a form of primary immunodeficiency disorder characterised by hypogammaglobulinemia and recurrent sino-pulmonary infections. Its diagnosis is based on the presence of low serum IgG (< 2 SD below normal for age) with or without low IgA/ IgM levels and presentation beyond two years of age. These children also have disorders of autoimmunity with majority of them presenting as autoimmune cytopenias, predominantly thrombocytopenia and some having anaemia and neutropenias. Here we report a nine years old boy with past history of recurrent pneumonia, presenting this episode with fungal pneumonia, thrombocytopenia and anaemia eventually diagnosed as CVID.

Abstract
Background Ultrasonography is the easily available, cheap and reliable method for evaluation of ovaries. Ovarian volume is the major factor in the diagnosis of various ovarian pathologies and confusing discrepancies are found in the literature. Objective To determine the ovarian volume among individuals attending outpatient department in tertiary level hospital. Method Descriptive cross sectional study design was used; 305 patients of 16-60 years attending general outpatient department in the Tribhuvan University Teaching Hospital, Kathmandu, Nepal were included. Ovarian volume was calculated by using transabdominal ultrasonography. Data was collected in the predesigned proforma and analyzed using statistical package for the social sciences software. Result The study showed mean total ovarian volume 5.95 ± 2.44 cc (centimeter cube) with mean right ovarian volume 5.94 ± 2.70 cc and mean left ovarian volume 6.05 ± 2.79 cc. Significant decrease in ovarian volume with age was observed. Height and weight did not show significant correlation with ovarian volumes and no significant variation seen in the volumes of right and left ovaries. Periovulatory ovaries show significantly higher volumes on right side than luteal phase. Similarly, significantly higher volume of left ovary seen in mixed ethnic group than mongoloid group. Conclusion Measurement of ovarian volume is important for evaluation and management of ovarian disorders. Ultrasonography which is readily available, simple and cost effective is better suited for our environment than other imaging modality. Values of ovarian volume from this study may provide a baseline of normal ovarian volume in our community.

Abstract
BACKGROUND Life style and jobs in current situations have generated increased free radicals such as hydroxyl (OH•) and superoxide (O2•) radicals, thereby increasing stress in humans. Interest in search of antioxidants that trap these free radicals has increased to relieve stress. β-carotene (provitamin A), ascorbic acid (vitamin C), tocopherol or vitamin E, Trolox; butyl hydroxy toluene and phenolic compounds are the well-known antioxidants. Several methods evaluate the antioxidant property existing in natural substances (medicinal plants and agri-food products) and synthetic compounds (2-methyl-3- (pyrrolidin-2-ylideneamino) quinazolin-4 (3H) -one and 3,3'- (1,4- phenylenebis (methanylylidene)) bis (azanylylidene) (2-methyl-quinazolin-4 (3H) -one). OBJECTIVE The objective of this study is to focus on complexes with p-hydroxycinnamic acids to trap free radicals in a greener way. METHODS Spectroscopic shifts and structural studies were employed to attribute electronic properties responsible for antioxidant profile. Spectroscopic shifts in wavenumbers were attributed with Fourier Transform Infrared Spectra (FTIR) and Fourier Transform Raman spectra (FT Raman Spectra). Structural studies were performed with Gaussian package, electron density method the B3LYP method, basis set 6-31(d) for attributing electronic properties responsible for antioxidant profile. RESULTS Interpretation of FTIR spectra revealed spectroscopic shifts in wavenumbers in all the complexes responsible for bonding. Further, studies confirmed the formation of complex with reduced intensities in Raman spectra. Computational studies revealed enhancement in molecular and electronic properties responsible for antioxidant power. CONCLUSION Studies revealed that complex with p-nitroaniline contribute to greater acceptor and donor power responsible for antioxidant power. These higher powers suggest the best antiradicals to trap free radicals.

Abstract
Scaffolds and implants in orthopaedics and regenerative dentistry usually fail because of bacterial infections. A promising solution would be the development of biomaterials with both significant regenerative potential and enhanced antibacterial activity. Working towards this direction, fluorapatite was synthesised and doped with Sr2+ and Ce3+ ions in order to tailor its properties. After experiments with four common bacteria (i.e. E. Coli, S. Aureus, B. Subtilis, B. Cereus), it was found that the undoped and the Ce3+ doped fluorapatites present better antibacterial response than the Sr2+ doped material. The synthesised minerals were incorporated into chitosan scaffolds and tested with Dental Pulp Stem Cells (DPSCs) to check their regenerative potential. As was expected, the scaffolds containing Sr2+-doped fluorapatite, presented high osteoconductivity leading to the differentiation of the DPSCs into osteoblasts. Similar results were obtained for the Ce3+-doped material, since both the concentration of osteocalcin and the RUNX2 gene expression were considerably higher than that for the un-doped mineral. Overall, it was shown that doping with Ce3+ retains the good antibacterial profile of fluorapatite and enhances its regenerative potential, which makes it a promising option for dealing with conditions where healing of hard tissues is compromised by bacterial contamination.
