Abstract
Students serve as ambassadors, conveying effective messages to encourage the adoption of promotes healthy behaviors. Recognizing their consciousness about corona illness 2019 (COVID-19), desires to utilize the COVID-19 vaccines, and other associated variables will aid in developing viable vaccination promotion tactics for the present COVID-19 pandemic. A transverse-segment internet poll of university students in the healthcare and non-healthcare industries was conducted to analyze their motivations to be vaccinated against the coronavirus. To recruit research participants, a random snowball sampling approach was utilized using digital media sites and mails. The contestants were chosen from throughout India, including several main geographic areas, between Nov-2020 and Jan-2021, prior to the release of the COVID-19 vaccination. There were descriptive metrics utilized to illustrate the research participants' socio-demographics and vaccine-related behaviors. Using logistic regression modeling, key characteristics that are expected to influence vaccination uptake among students were modeled. p 0.06 was judged substantial in each study. 656 students participated in the study, with 48.4% coming from the healthcare sector & 51.5% from other fields. Of these 655 students, 43.6 and 22.4% came from India's northern and eastern areas. Graduate students accounted for 41.1% of the total population, and graduates for around 43.2%. The age range of 56.0% of the students was 18 to 25. Women made up 62% of the population, and 69.5% of them were unmarried. Seventy-eight percent of the students were from the medium socioeconomic level. Concerns about side effects and safety, distrust of government officials, and questions about the vaccine's efficacy were among the reasons given by students in this study for their reluctance to get vaccinated. It is essential to remember that these investigations were carried out at various times and in various nations; thus, the conclusions may not apply to all college students throughout the globe. According to the findings of this research, Indian university students showed rather a great deal of motivating desire to acquire COVID-19 immunizations. The people were either doubtful or reluctant to get the vaccination, which suggests possible vaccine aversion. There is a need for information campaigns and other actions to lessen vaccine hesitancy in order to promote the usage of COVID-19 vaccines.

Abstract
Aim and background Imaging is indispensable to the diagnostic and treatment process. By facilitating access to rapid timely image interpretation, teleradiology plays a prominent role in improving access, quality of critical care, and management of the patients in intensive care units (ICU). The aim of the study is to investigate the role of teleradiology in ICU patient care and management. Materials and methods In our study, a total of 22,081 studies of a cohort of 14,900 patients which had been transmitted from intensive care units of 80 hospitals located across the United States of America through a teleradiology reporting workflow, were interpreted by the American Board Certified Radiologists empanelled by a teleradiology service provider, located in India. Results Among all modalities, the highest percentage of studies performed were computed tomography scan (47%) followed by radiographs (37.22%). Out of 22,081 cases under the study, 16,582 cases were reported during nighttime with a mean turnaround time (TAT) of 46.66 minutes 95% CI (46.27-47.04) while 5,499 cases were reported during daytime with a mean TAT of 44.66 minutes 95% CI (45.40-43.92). Conclusion Setting up teleradiology service connectivity with a teleradiology service provider located in India, providing high-quality diagnostic interpretations and lower turnaround time with the ICUs in the US hospitals reduces the interval to intervention time and leads to efficient patient care management. Moreover, it also provides time advantage for US hospitals when on-site radiologists at night are unable to provide immediate coverage. Clinical significance The ICU teleradiology service model designed in the study would greatly help overcome the shortfall of radiologists in the hospitals, provide better patient management and care by quality reporting in short turnaround time, not only during daytime but also in the night hours or on holidays when on-site radiologists are unable to provide immediate coverage.

Abstract
INTRODUCTION Chronic liver disease very often culminates into cirrhosis and its associated complications. One of the serious complications is portal venous thrombosis, which can occur due to a variety of risk factors. One significant factor contributing to portal hypertension is portal vein thrombosis (PVT). In this study, we aimed to investigate the prevalence of PVT among patients with liver cirrhosis in a tertiary hospital and identify the factors associated with this complication. METHODOLOGY This was a cross-sectional observational study of 93 diagnosed liver cirrhosis patients treated at Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) hospital in southern India between June 2020 and January 2021. A thorough evaluation of the clinical condition of the patients and associated comorbidities was done. The patients then underwent Doppler ultrasound/CECT/MRI to look for PVT and its extent. The collected data were analyzed using Statistical Product and Service Solutions (SPSS, version 24) (IBM SPSS Statistics for Windows, Armonk, NY). Comparison between two proportions was done using two two-tailed Z-test/Fisher's exact tests. RESULTS Our study found a PVT prevalence of 17.2% in cirrhotic patients, with a higher prevalence of acute PVT than chronic PVT. Ascitic fluid infection, longer duration of cirrhosis, and increased cirrhosis severity were significantly associated with PVT development. We found no significant associations between PVT and gender, hypertension, smoking, diabetes, or the duration of alcohol intake. CONCLUSION This study highlights the importance of early screening for PVT using Doppler USG in all patients diagnosed with cirrhosis. Additionally, anticoagulation therapy for acute PVT may be considered in patients without bleeding risks.

Abstract
To examine the changes of upper airway cross sectional area in each phase of respiration in different degrees of severity of OSAS with computed tomography and cephalometry to decide on further treatment. A Prospective study was done in the Department of Radiology and Imaging, Kasturba Medical College, Mangalore, spanning over a period from March 2017 to December 2019. 50 patients were included in the study including control group. Patients who had at least 2-3 major symptoms of sleep apnea such as snoring, daytime somnolence, and apnea were included in this study. All patients were examined and then subjected to polysomnography(PSG) and upper airway CT. Patients with apnea-hypopnea index (AHI) of < 5 on Polysomnography were included in the control group and those with AHI of > 5 were categorized in to the study group Cross-sectional area of the airway at the level of the nasopharynx, oropharynx and the hypopharynx were obtained. Standard cephalometric measurements were made on a lateral radiograph of skull/ CT scanogram. Of the 36 patients in the study group, 31 patients were males and 5 were females. In the control group of 12 patients, 8 were males and 4 females. The cross sectional area at the lower border of the nasopharynx which is also the level of the nasopharyngeal sphincter was the most affected level in OSAS (p value of < 0.0001). Mean uvular diameter in the control group was 9.6 mm and in the OSAS group it was 11.2 mm. The mean length of the soft palate was 36.4 mm in the controls, 39.5 mm in the mild/moderate OSAS and 41.2 mm in the severe OSAS group. Obstructive sleep apnea is a complex disorder characterized by apneic episodes during sleep. In this study the most common site of obstruction is nasopharyngeal sphincter and the oropharynx. Although PSG is the diagnostic test of choice, imaging plays an important role in planning surgical and conventional treatment.

Abstract
Waste Management in India has always been a severe problem, and tackling this issue would require a social mindset towards adopting green practices. This study aims to understand the consumer mindset and awareness of recycling in India and explore factors that could influence India’s recycling behavior. The data for this study has been obtained through a primary research – survey questionnaire. Correlation analysis and regression have been applied to understand the result of the questionnaire data. Promoting recycling amongst people takes into consideration many factors. The results suggest that recycling behavior is mostly influenced by factors, such as willingness to adopt environment-friendly behavior, awareness towards recycling, and providing incentives. This study aimed to explore recycling in India and study the major factors that can influence people to adopt recycling. It also explored a possible relationship between providing incentives and influencing recycling behavior. These findings will help to analyze and develop strategies to boost the recycling rate in India.

Abstract
Abstract
Introduction
Transforaminal Lumbar Interbody Fusion (TLIF) is a technique used for the management of various pathologies such as degenerative disc disease, recurrent disc herniations and spondylolisthesis, to mention the most common indications. There is an ongoing debate regarding the use of open versus minimally invasive techniques for TLIF. Each has its own advantages and disadvantages. In the present study, we aim to present our experience regarding the use of open vs MIS TLIF at Stepping Hill Hospital in Manchester.
Method
A retrospective observational cohort study involving 60 patients was conducted at Stepping Hill Hospital in the UK. Patients who had TLIF surgery between 2019 and 2020 were included. Patients were consecutively allocated to either the open TLIF or the MIS TLIF group. Data were collected from hospital records including pre- and post-operative follow up notes. We also assessed pain score using the visual analogue scale.
Results
26 patients underwent MIS TLIF whereas 34 patients underwent an open procedure. The MIS group showed better outcomes compared to the open group in terms of post-operative complications, improvement of symptoms and the average hospital stay: 7.6% vs 8.8%, 73.7% vs 58.8% and 1.82 vs 2.76 days, however, the open group had a lower rate of metalwork failure 8.8% vs 11.5% in the MIS.
Conclusions
Our study showed that MIS TLIF at our unit seems to result in better outcomes related to symptoms alleviation, post-operative complications and less hospital stay despite having a slightly higher rate of metalwork failure.

Abstract
Abstract
Aim
The COVID-19 pandemic has resulted in significant pressures on the NHS. Healthcare workers (HCWs) are at increased risk of infection. Personal protective equipment (PPE) lowers the risk of infection transmission. However, during the early phases of the pandemic, the information available regarding COVD-19 and the use of PPE has been unclear, with constantly changing guidelines. The aim of this study was to determine the knowledge and confidence about PPE usage among HCWs, in addition to measuring their anxiety levels during the COVID pandemic.
Method
A validated questionnaire was distributed among HCWs in as many UK hospitals as possible, during April 2020. The questionnaire consisted of 13 questions regarding demographics, knowledge on PPE guidance, HCW training and confidence levels in PPE usage and finally anxiety levels measured using the GAD-7 psychometric tool.
Results
1055 responses were received. Nurses (49%), Healthcare Assistants (HCA - 20%), Doctors (17%), Physios (8%) and other (6%). 99% of respondents indicated they were familiar with PPE guidance, but only 1.6% answered all 3 questions on PPE guidance accurately. 86.4% of respondents received mask-fitting checks. 79.7% received donning-doffing training. Despite this, only 46.8% were confident on their familiarity with PPE. 32.5% felt that their hospital communication regarding PPE policy during COVID-19 pandemic was poor or very poor. 30% HCWs experienced severe anxiety.
Conclusions
National guidance and local training on PPE usage during the COVID-19 pandemic has been unsatisfactory, leading to higher anxiety among HCWs. Improved information delivery and training are essential in preparation for the second wave and future pandemics.

Abstract
There is paucity of published data related to eosinophilic gastroenteritis (EGE). We aimed to study the clinical characteristics, management, and follow-up of EGE. From March 2014 to December 2018, patients with gastrointestinal (GI) symptoms suspected to have EGE were investigated. This is a retrospective study. Complete blood count, upper GI endoscopy (UGIE), and biopsy were done. Contrast-enhanced computed tomography (CECT) abdomen was done when intestinal obstruction was suspected. Laparoscopic small bowel resection or stricturoplasty and full-thickness biopsy were obtained. EGE was diagnosed if the biopsies showed eosinophilic infiltration of one or more regions of the GI tract (> 30 eosinophils per high power field [HPF]). Patients were treated with immunosuppressive therapy and if indicated surgery. Clinical response to therapy was assessed and patients were followed up for 1 year. Forty-one patients (mean age 34.8 years, median age 32, range 25-70 years, 29 males) had EGE. Upper abdominal pain was the most common symptom. Peripheral eosinophilia was present in 82.9% patients. On UGIE, duodenal lesions were observed in 75% patients. EGE was confirmed in 37 patients by endoscopic duodenal biopsies, in 2 patients by jejunal mucosal biopsies using enteroscopy, and in 2 patients by full thickness surgical biopsies. Forty-one patients were treated with oral corticosteroids inclusive of 4 patients who underwent surgery. Of the 37 patients, 6 were lost to follow-up; 31 patients were followed up for a period of 1 year. All the patients who were treated with corticosteroids responded to initial therapy. Over a follow-up period one case had frequent relapses. EGE should be suspected in patients with upper abdominal pain. Peripheral eosinophilia occurs in the majority. Tissue diagnosis showing eosinophilic infiltration is diagnostic. Oral corticosteroid therapy is highly effective and relapse is rare.

Abstract
Polyethylene glycol diacrylate (PEGDA) is an important class of photosensitive polymer with many tissue engineering applications. This study compared PEGDA and polycaprolactone (PCL) nanofiber matrix (NFM) coated PEGDA, referred to as PCL-PEGDA, scaffolds for their application in multiple tissue repair such as articular cartilage, nucleus pulposus of the intervertebral disc (IVD). We examined each scaffold morphology, porosity, swelling ratio, degradation, mechanical strength, andin vitrocytocompatibility properties. A defect was created in Sprague Dawley rat tail IVD by scraping native cartilage tissue and disc space, then implanting the scaffolds in the disc space for 4 weeks to evaluatein vivoefficacy of multi-tissue repair. Maintenance of disc height and creation of a new cell matrix was assessed to evaluate each scaffold's ability to repair the tissue defect. Although both PEGDA and PCL-PEGDA scaffolds showed similar porosity ∼73%, we observed distinct topographical characteristics and a higher effect of degradation on the water-absorbing capacity for PEGDA compared to PCL-PEGDA. Mechanical tests showed higher compressive strength and modulus of PCL-PEGDA compared to PEGDA.In vitrocell studies show that the PCL NFM layer covering PEGDA improved osteoblast cell adhesion, proliferation, and migration into the PEGDA layer.In vivostudies concluded that the PEGDA scaffold alone was not ideal for implantation in rat caudal disc space without PCL nanofiber coating due to low compressive strength and modulus.In vivoresults confirm that the PCL-PEGDA scaffold-maintained disc space and created a proteoglycan and collagen-rich new tissue matrix in the defect site after 4 weeks of scaffold implantation. We concluded that our developed PCL-PEGDA has the potential to be used in multi-tissue defect site repair.

Abstract
Inositol hexakisphosphate (InsP6; phytic acid) is considered as the second messenger and plays a very important role in plants, animals, and human beings. It is the principal storage form of phosphorus in many plant tissues, especially in dry fruits, bran, and seeds. The resulting anion is a colorless species that plays a critical role in nutrition and is believed to cure many diseases. A fluoresceinated aminohexanol tethered inositol hexakisphosphate (III) had been synthesized earlier involving many complicated steps. We describe here a simple two-step synthesis of (III) and its characterization using different techniques such as matrix-assisted laser desorption ionization mass spectrometry, tandem mass spectrometry, and Fourier transform infrared, ultraviolet-visible, ultraviolet-fluorescence, 1H nuclear magnetic resonance (NMR), and two-dimensional NMR spectroscopies. The effect of (III) has been investigated in the model systems, Arabidopsis thaliana and Drosophila melanogaster. Using Schrodinger software, computational studies on the binding of (III) with the protein 2P1M (Auxin-receptor TIR1-adaptor ASK1 complex) has revealed strong binding propensity with this compound. These studies on the fluoresceinated tethered phytic acid could have far reaching implications on its efficacy for human health and treatment of diseases (cancer/tumor and glioblastoma) and for understanding phosphorous recycling in the environment, especially for plant systems.

Abstract
BACKGROUND Major liver resection is associated with blood loss and transfusion. Observational data suggest that hypovolaemic phlebotomy can reduce these risks. This feasibility RCT compared hypovolaemic phlebotomy with the standard of care, to inform a future multicentre trial. METHODS Patients undergoing major liver resections were enrolled between June 2016 and January 2018. Randomization was done during surgery and the surgeons were blinded to the group allocation. For hypovolaemic phlebotomy, 7-10 ml per kg whole blood was removed, without intravenous fluid replacement. Co-primary outcomes were feasibility and estimated blood loss (EBL). RESULTS A total of 62 patients were randomized to hypovolaemic phlebotomy (31) or standard care (31), at a rate of 3·1 patients per month, thus meeting the co-primary feasibility endpoint. The median EBL difference was -111 ml (P = 0·456). Among patients at high risk of transfusion, the median EBL difference was -448 ml (P = 0·069). Secondary feasibility endpoints were met: enrolment, blinding and target phlebotomy (mean(s.d.) 7·6(1·9) ml per kg). Blinded surgeons perceived that parenchymal resection was easier with hypovolaemic phlebotomy than standard care (16 of 31 versus 10 of 31 respectively), and guessed that hypovolaemic phlebotomy was being used with an accuracy of 65 per cent (20 of 31). There was no significant difference in overall complications (10 of 31 versus 15 of 31 patients), major complications or transfusion. Among those at high risk, transfusion was required in two of 15 versus three of nine patients (P = 0·326). CONCLUSION Endpoints were met successfully, but no difference in EBL was found in this feasibility study. A multicentre trial (PRICE-2) powered to identify a difference in perioperative blood transfusion is justified. Registration number: NCT02548910 ( http://www.clinicaltrials.gov).

Abstract
Undergraduate research experiences in science, technology, engineering, and mathematics fields are championed for promoting students' personal and professional development. Mentorship is an integral part of undergraduate research, as effective mentorship maximizes the benefits undergraduates realize from participating in research. Yet almost no research examines instances in which mentoring is less effective or even problematic, even though prior research on mentoring in workplace settings suggests negative mentoring experiences are common. Here, we report the results of a qualitative study to define and characterize negative mentoring experiences of undergraduate life science researchers. Undergraduate researchers in our study reported seven major ways they experienced negative mentoring: absenteeism, abuse of power, interpersonal mismatch, lack of career support, lack of psychosocial support, misaligned expectations, and unequal treatment. They described some of these experiences as the result of absence of positive mentoring behavior and others as actively harmful behavior, both of which they perceive as detrimental to their psychosocial and career development. Our results are useful to mentors for reflecting on ways their behaviors might be perceived as harmful or unhelpful. These findings can also serve as a foundation for future research aimed at examining the prevalence and impact of negative mentoring experiences in undergraduate research.

Abstract
Abstract
Introduction
Optogenetics is a low-invasive, flexible and highly selective intervention that enables electrical excitation with light on myocardium overexpressing light-sensitive proteins. Optical illumination can control the simultaneous exciting of the whole myocardium under the spot, which is more conducive to recovery from electrical disturbance to sinus rhythm.
Purpose
We explored optogenetic defibrillation for different illumination parameters how to affect defibrillation rates and the possible mechanism of continuous illumination defibrillation.
Methods
Systemic delivery via right jugular vein injection of (AAV9-CAG-hChR2(H134R)-mCherry) were performed in juvenile SD rats to achieve the light sensitive protein Channelrhodopsin-2 (ChR2) transfer throughout the whole heart. We intubated and ventilated rats, opened chest and recorded the ECG. After ligation of the left anterior descending coronary artery, ventricular arrhythmia was induced by electrical burst stimulation (10v, 50Hz, 2s). Cardiac epicardium illumination with 470nm blue laser was performed to investigate the effects of optogenetic defibrillation and its underlying mechanism. Every heart accepted 30 pulses of 20ms duration on 8Hz to test the light intensity threshold for 1:1 capture. Different illumination modes of multiple light intensity (2,4,8,10,20 times threshold intensity), pulse duration (20, 50, 200, 500 and 1000ms) and illumination position (RV apex, RV, RVOT, septum, LV) were applied in each attempt for 4 repetitions with 1 s interval.
Results
We demonstrated that ventricular arrhythmias could be terminated by illumination of the right ventricle at 20 times threshold intensity in 1s (figure A) with the successful defibrillation rate of 95±2.673% (mean ±SEM; N=7). Herein, the successful optogenetic defibrillation rate was strongly depending on light intensity (N=5, n=50 episodes, p=0.0118) and duration of illumination (N=5, n=50 episodes, p<0.0001) (figure B.C). Notably when there were higher intensity and longer pulse duration, the higher defibrillation rate appeared. There was no significant difference in the defibrillation rate among different illumination positions (N=5, n=25episodes per position, p=0.1177) (figure D). To explore the underlying mechanism of optogenetic defibrillation, we performed the same illumination mode during sinus rhythm in 2 rats (figure E. F. G). We observed that higher light intensity and longer pulse duration were more conducive to induce an episode of higher frequency focal excitement.
Views of optogenetic defibrillation
Conclusions
We demonstrated that optogenetic defibrillation is a highly effective intervention and the possible mechanism is partly attributed to overdrive suppression. We believe that optogenetic approach is potentially to be translated into more efficient and pain-free clinical termination of ventricular arrhythmia.

Abstract
Abstract
Background
The optogenetics manipulation of the heart based on the visible light is limited in the therapeutic potential because of the low tissue penetration. Near-infrared (NIR) light has deeper tissue penetration capabilities but radiates at unsuitable wavelengths, while upconversion nanoparticles (UCNPs) absorb NIR light to convert visible light.
Purpose
We aimed to investigate the efficient NIR control of the rat heart in vivo via UCNPs mediated cardiac optogenetics.
Methods
Systemic delivery via jugular vein injection of (AAV9-CAG-hChR2 (H134R)-mCherry) were performed in SD rats to achieve sufficient Channelrhodopsin-2 (ChR2) transfer throughout the whole heart. UCNPs of NaYF4:Yb/Tm with optimal excitation wavelength at 975nm were chosen to emit upconverted blue light. Different concentrations of UCNPs cyclohexane solution were embed in composite polydimethylsiloxane films to make flexible substrates for cardiac optogenetics study in open-chest rats (n=3). The UCNPs film was attached to the right ventricle and the 980nm NIR illumination was applied.
Results
The upconversion luminescence spectra of four concentrations (2.5, 5, 10 and 20mg/ml) of NaYF4:Yb/Tm scanned under 980nm excitation at 0.5w showed similar peaks around 475, 645 and 695nm. Emission intensity increased with the UCNPs concentration (Figure 1). The NIR-upconverted blue light from the freestanding films embedded with 2.5 and 5mg/ml UCNPs failed to capture the heart till the peak output power of the NIR laser, and the hearts were successfully captured and paced by the upconverted blue light from 10 and 20mg/mL UCNPs films (20 pulses in 8Hz with 20ms duration were repeated 3 times with the interval of 1s). However the NIR power was lower on 10mg/mL UCNPs film than the 20mg/mL one (0.93±0.11w vs 1.71±0.75w). Therefore, UCNPs film with concentration of 10mg/mL NaYF4:Yb/Tm were used for efficient cardiac optogenetic pacing by NIR light from a 400um optical fiber. Optogenetics capture of the ventricle was achieved at different NIR power, pulse duration and flash frequency. The strength-duration curve summarized the minimal NIR irradiance power of 8Hz flash required for 100% capture at different pulse duration (2, 5, 10, 20 and 50ms). Notably the longer the pulse duration was, the lower the light intensity required. Furthermore, the increasing flash frequency (6, 7, 8 and 10Hz) of the NIR light setting at 1.66w (2-fold threshold power) and 20ms duration induced sufficient cardiac pacing (Figure 2).
The efficient NIR control of the heart
Conclusion
We demonstrated the successful NIR photo-activation of ChR2 expressed in the heart by the upconverted blue light via UCNPs, which resulted in a flexible UCNPs-assisted cardiac optogenetic approach for optical control of heart activity. We believe that these advances in cardiac optogenetic toolbox not only represent a novel practical application of UCNPs, but also open up new possibilities for remote or tissue penetrating heart control.

Abstract
OBJECTIVE The role of serotonin (5-HT) in human aggression has been the subject of a large number of studies, mostly with adults. Meta-analyses indicate a small but significant inverse relationship between central nervous 5-HT availability and aggression, but genetically informed studies suggest two pathways: one to reactive aggression and the other to proactive aggression. METHOD We conducted a systemic review on central nervous 5-HT function in children and adolescents, with attention to the function of aggression. RESULTS In total, 675 articles were screened for relevance, with 45 reviewed. These included blood assays (e.g. plasma, 5-HIAA; platelet 5-HTR2A ), epigenetic studies, retrospective PET studies and 5-HT challenge paradigms (e.g. tryptophan depletion). Overall, findings were mixed, with support both for negative and for positive associations of central nervous 5-HT function with aggression in children and adolescents. CONCLUSION We propose factors that may be blurring the picture, including problems in the conceptualization and measurement of aggression in young people, the lack of prospective designs and the bias towards clinical samples of boys. Research needs to account for variance in the both motivation for and implementation of aggression, and look to the behavioural economics literature to consider the roles of reward, vengeance and self-control more clearly.

Abstract
We report on quantum capacitance measurements of high quality, graphite and hexagonal boron nitride encapsulated Bernal stacked trilayer graphene devices. At zero applied magnetic field, we observe a number of electron density- and electrical displacement-tuned features in the electronic compressibility associated with changes in Fermi surface topology. At a high displacement field and low density, strong trigonal warping gives rise to three new emergent Dirac cones in each valley, which we term "gullies." The gullies are centered around the corners of a hexagonal Brillouin zone and related by threefold rotation symmetry. At low magnetic fields of B=1.25 T, the gullies manifest as a change in the degeneracy of the Landau levels from two to three. Weak incompressible states are also observed at integer filling within these triplet Landau levels, which a Hartree-Fock analysis indicates are associated with Coulomb-driven nematic phases that spontaneously break rotation symmetry.

Abstract
Lymphangioma of the pancreas is rare and presents as a large cystic mass in the retroperitoneum. The pancreatic origin can be confirmed by careful evaluation of cross sectional imaging. Preoperative differentiation from other pancreatic cystic neoplasms is difficult but possible. Large symptomatic lesions warrant surgery. The diagnosis is confirmed by typical features on histopathology and immunohistochemistry. Presented here is a case report of a pancreatic lymphangioma, discussed in the context of available literature.

Abstract
INTRODUCTION Recurrent miscarriage (RM) defined as 2 or more spontaneous miscarriage before 20 weeks of gestation, affects at least 1 % of couples trying to conceive. In over 50 % of cases, the cause of the loss of pregnancy remains unexplained. Reduced expression of Angiogenic factors such as: vascular endothelial growth factor (VEGF-A) and VEGF-C has been linked with spontaneous miscarriage, likely due to defective foetal and placental angiogenesis. AIMS AND OBJECTIVES To investigate the relationships between serum level of VEGF-A and VEGF-C with clinical characteristic in women with URM and compare to pregnant and healthy women. MATERIALS AND METHODS A case-control study, which was conducted between 90 non-pregnant women with history of RM, age-matched with 70 non-pregnant women without history of recurrent abortion with at least one child (controls) and 70 pregnant women without history of recurrent abortion with at least one child (controls). Those with unexplained RM were eligible. Demographic and Anthropometric data were retrieved by pre-test questionnaire and serum level of VEGF-A and VEGF-C measured by ELISA kit. RESULTS This study showeds that maternal levels of VEGF-A and VEGF-C were distinctly lower in RSA (189.87±88.1 vs 238.8±99.6) compared to healthy (239.1±99.7 vs 275.5±133.08) and pregnant (301.5±76.4 vs 402.5±128.6) women as control groups. Univariate analysis demonstrated that clinical characteristic factors were significantly associated with concentration of VEGF-A and VEGF-C in cases and controls. CONCLUSIONS Our findings suggest that these molecules could be used as potential predictive markers of miscarriage in these women presenting with URM (Tab. 4, Fig. 5, Ref. 40).

Abstract
Natural Language Processing (NLP) is essential for concept extraction from narrative text in electronic health records (EHR). To extract numerous and diverse concepts, such as data elements (i.e., important concepts related to a certain medical condition), a plausible solution is to combine various NLP tools into an ensemble to improve extraction performance. However, it is unclear to what extent ensembles of popular NLP tools improve the extraction of numerous and diverse concepts. Therefore, we built an NLP ensemble pipeline to synergize the strength of popular NLP tools using seven ensemble methods, and to quantify the improvement in performance achieved by ensembles in the extraction of data elements for three very different cohorts. Evaluation results show that the pipeline can improve the performance of NLP tools, but there is high variability depending on the cohort.

Abstract
Caracinosarcomas are tumours with diverse epithelial and mesenchymal differentiation. They most commonly occur in the female reproductive organs and upper aero digestive tract. They are relatively rare in the gastrointestinal tract and affect the oesophagus most commonly. Ampullary carcinosarcomas are exceptionally rare. We report a case of ampullary carcinosarcoma in a 67-year-old male, with osteosarcomatous, small cell carcinoma and conventional adenocarcinoma components. To the best of our knowledge, this is the first reported case of its kind.
