Abstract
This study aims to comprehensively characterize 576 inhibitors targeting Spleen Tyrosine Kinase (SYK), a non-receptor tyrosine kinase primarily found in haematopoietic cells, with significant relevance to B-cell receptor function. The objective is to gain insights into the structural requirements essential for potent activity, with implications for various therapeutic applications. Through chemoinformatic analyses, we focus on exploring the chemical space, scaffold diversity, and structure-activity relationships (SAR). By leveraging ECFP4 and MACCS fingerprints, we elucidate the relationship between chemical compounds and visualize the network using RDKit and NetworkX platforms. Additionally, compound clustering and visualization of the associated chemical space aid in understanding overall diversity. The outcomes include identifying consensus diversity patterns to assess global chemical space diversity. Furthermore, incorporating pairwise activity differences enhances the activity landscape visualization, revealing heterogeneous SAR patterns. The dataset analysed in this work has three activity cliff generators, CHEMBL3415598, CHEMBL4780257, and CHEMBL3265037, compounds with high affinity to SYK are very similar to compounds analogues with reasonable potency differences. Overall, this study provides a critical analysis of SYK inhibitors, uncovering potential scaffolds and chemical moieties crucial for their activity, thereby advancing the understanding of their therapeutic potential.

Abstract
AIM To enhance ultrasound teaching delivery to radiology trainees using a simulation course matched to the 2021 Royal College of Radiologists (RCR) curriculum. MATERIAL AND METHODS An ultrasound simulation training course was designed for specialty trainees (ST) 1 in radiology, which was based on the 2021 RCR curriculum and covered the top ultrasound training priorities. The course was piloted initially on two occasions in a 1-day format to the August 2021 and the March 2022 ST1 intake trainees. Based on the feedback, a comprehensive 4-day course was developed and delivered between October and December 2022 for the August 2022 ST1 intake, funded by Health Education England. The outcomes measured were subjective trainee feedback using numerical scores and free text. RESULTS All King's College Hospital NHS Foundation Trust radiology ST1 trainees from the August 2021 to the August 2022 intake participated in ultrasound simulation training. The training matched the RCR curriculum and increased the trainees' confidence and competency in medical ultrasound. CONCLUSIONS Ultrasound simulation training can be successfully delivered to ST1 trainees to match the 2021 RCR curriculum and enhance training in medical ultrasound for radiologists.

Abstract
OBJECTIVES This study aimed to evaluate whether the Families First Coronavirus Response Act (FFCRA) modified the association between pre-existing state paid sick leave (PSL) and weekday workplace mobility between February 15 and July 7, 2020. STUDY DESIGN This was a longitudinal, observational study. METHODS The 50 US states and Washington, D.C., were divided into exposure groups based on the presence or absence of pre-existing state PSL policies. Derived from Google COVID-19 Community Mobility Reports, the outcome was measured as the daily percent change in weekday workplace mobility. Mixed-effects, interrupted time series regression was performed to evaluate weekday workplace mobility after the implementation of the FFCRA on April 1, 2020. RESULTS States with pre-existing PSL policies exhibited a greater drop in mobility following the passage of the FFCRA (β = -8.86, 95% confidence interval: -11.6, -6.10, P < 001). This remained significant after adjusting for state-level health, economic, and sociodemographic indicators (β = -3.13, 95% confidence interval: -5.92, -0.34; P = .039). CONCLUSIONS Pre-existing PSL policies were associated with a significant decline in weekday workplace mobility after the FFCRA, which may have influenced local health outcomes. The presence of pre-existing state policies may differentially influence the impact of federal legislation enacted during emergencies.

Abstract
BackgroundPoor health-related quality of life (HR-QoL) is recognised in patients with established connective tissue diseases (CTDs), however it is not clear how it affects patients with undifferentiated CTD (UCTD) which has traditionally been associated with a mild or more benign profile.ObjectivesTo investigate HR-QoL in patients affected with a variety of CTDs (including UCTD) using the SF-36 questionnaire; and secondly, to review demographic and clinical factors predictive of a poor HR-QoLMethodsThe Lupus Extended Autoimmune Phenotype (LEAP) cohort is a multicentre prospective study of patients with a CTD. Rheumatologist diagnosis was used to classify patients into four groups: systemic lupus erythematosus (SLE), primary Sjögren’s syndrome (pSS), UCTD, and (combined because of low numbers) those with an idiopathic inflammatory myopathy (IIM), systemic sclerosis (SSc) or overlap syndrome. The SF-36 quality of life questionnaire was completed at enrolment and includes eight domains: physical function (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE) and mental health (MH) which range from 0 to 100, with higher scores reflecting better HR-QoL. Physical (PCS) and mental component score (MCS) were calculated for each group, with a score below 50 representing a worse HR-QoL compared to the general UK population. Predictors for poor HR-QoL was chosen a priori, then tested using linear regression adjusted for age, gender and ethnicity. All statistical analysis was performed using STATA v14, with results expressed as beta coefficients with 95% confidence intervals (95%CI).ResultsData were collected from 309 patients (280 [90.6%] women, with a mean [SD] age of 48.9 [12.9] years) from three UK rheumatology centres. The majority of patients were Caucasian (n=235, 76.1%). By rheumatologist diagnosis, 115 (37.2%) had SLE, 56 (18.1%) pSS, 72 (23.3%) UCTD and 66 (21.4%) SSc, IIM or an overlap syndrome. Patients with UCTD, pSS and SSc/IIM spectrum disorders had a shorter median disease duration (3.8, 3.7 and 6.1 years respectively) compared with patients with those with SLE (11.0 years), p<0.001. Previous steroid and immunosuppressant use was highest in patients with SLE and SSc/IIM spectrum disorders (p<0.001). The most affected domains include VT, GH and BP (Figure 1), and the PCS is more impaired compared with the MCS, with similar scores across disease groups. Agnostic of disease group, factors associated with a lower PCS include increasing age (beta -0.15 [95%CI -0.26, -0.06], p=0.008), prednisolone use (-3.1 [-6.05, -0.19], p=0.037), c-reactive protein (-0.09 [-0.62, -0.10], p=0.007), fatigue (-2.00 [-3.79, -0.22], p=0.028), and sicca syndrome (-4.70 [-7.66, -1.74] p=0.002), and these remained significant in a multivariate model.Figure 1.radar diagrams of eight SF-36 domains, and MCS and PCS boxplots.

Abstract
Background and Aims : This study aims to evaluate the implication of peer-assisted learning model adopted in students' clinical skills training from the perspective of tutees and tutors at the end of a peer-tutored clinical skills program and peer tutors themselves. Subjects and Methods This cross-sectional study was conducted in the Faculty of Medicine, Bursa Uludag in between January and March 2018. Following the clinical skills training, a questionnaire designed to assess the views of tutees and peer tutors was filled out on a voluntary basis by 159 tutees and 43 tutors. The statistical analysis of the collected and processed data was analyzed by using IBM SPSS 23.0 statistical program. The statistical significance level was maintained as α = 0.05. Results According to the Likert scale, satisfaction with the tutors and the educational environment was high in general. The 2nd term tutees provided more negative feedback compared to other terms. Among all the terms, the most positive answers were provided by the 3rd term students. Although the tutors found themselves fully skilled in communication with colleagues, there were striking differences between the tutors in the 5th and 6th terms of providing a good role model for pre-clinical terms students. Conclusion Considering peer assisted learning (PAL)'s positive responses from this study, the adoption of PAL has been started to be used as a supplementary teaching method for the clinical skills training at the Faculty of Medicine, Bursa Uludag University. PAL is considered a successful education model since it is cost-efficient for undergraduate medical training and improves the professional skills of both teacher and learner students. It can be availed of as an alternative method in medical faculties where especially the number of academic members is insufficient.

Abstract
The patient with diabetes mellitus (DM) and its complication is increasing in our country and all over the world. Fibrinogen is a renowned factor of progressive atherosclerotic lesions and a predictor of cardiovascular events. Level of fibrinogen is increases in patients with diabetes mellitus (DM) may accelerate thromboembolic risk for cardiovascular disease (CVD). This study was carried out to assess plasma fibrinogen level in subjects with type 2 diabetes mellitus. It was a cross sectional analytic study and conducted in the Department of Physiology, Dhaka Medical College, Dhaka, Bangladesh from July 2013 to June 2014. A total number of 200 adult male subjects were selected with age ranging from 40-60 years. Among them, 100 subjects with type 2 diabetes mellitus were included in the study group (Group B) and 100 healthy subjects with same age range were considered as controls (Group A) for comparison. The subjects were selected from BIRDEM hospital Dhaka and personal contact from different areas of Dhaka city on the basis of exclusion and inclusion criteria. The study parameter was plasma fibrinogen level, and was measured in the Department of Microbiology and Immunology of BIRDEM hospital, Dhaka, Bangladesh. The data were collected and recorded in pre-designed structured questionnaire by the researcher herself. For statistical analyses unpaired Student's 't' test and Pearson's correlation coefficient (r) test were performed as applicable using SPSS for windows version 19.0. In this study plasma fibrinogen level was significantly (p<0.001) higher in the study group than that of control group. From this study, it may be concluded that estimation of plasma fibrinogen level might be beneficial for prediction of future cardiovascular risk in adult diabetic male.

Abstract
Abstract
Aim
Which theories, concepts and frameworks have been evidenced for surgical innovation in leadership in the United Kingdom, European Union, and the United States of America?
Method
Systematic scoping synthesis of literature will be employed where appropriate theories, concepts and frameworks will be identified. Drawing upon broader literature on leadership innovation in surgery further examples will be utilised within surgery. s and full- text articles will be used and reviewed for relevance to the research question against an inclusion and exclusion criteria.
Results
The theories of innovative leadership in surgery are broad and non-specific. It demands a professionalism, competence, teamwork, and motivation. Upon comparison of the three country/region profiles there are strong similarities but present differences. It is paramount to understand and underpin these theories in order to foster the future of innovation in surgery. Surgery is fast evolving and developments in leadership must evolve with it. Within innovation, leadership skills must be harnessed including experience and observation. It is through an interprofessional team that surgeons must collaborate in order to provide optimum results and to permit the profession to evolve.
Conclusions
Innovation and surgery are symbiotic, and the next generation of surgical leaders must foster an environment where this is possible to cultivate. Programmes across these country profiles must ensure innovative leadership is present through good mentorship, coaching, team empowerment and feedback. Future directions must be put in place in post -graduate surgical training programmes to ensure that patient care is optimised as the primary objective.

Abstract
Abstract
Aim
Oesophageal and gastric cancers are the eighth and fifth most prevalent cancers with a high degree of morbidity and mortality. Oesophagogastric resections are associated with a high degree of complications postoperatively. Complications following resection are associated with poorer hospital recovery, recurrence of cancer, readmission to hospital and increased mortality. A study was carried out to examine if there was an association between post-operative bloods and the development of complications.
Method
Data was collected from theatre logbooks, Integrated Clinical Environment (ICE) and clinical portal. Patients undergoing oesophagogastric resection for gastric and oesophageal cancer between October 2010 and November 2014 were included. Complications were organised using the Clavien Dindo classification. Data was analysed using the Student’ T test and Chi-Squared test. A P-value of 0.05 was classed as being statiscally significant.
Results
94 patients met the inclusion criteria for this study. 55 patients (58.5%) underwent Oesophagectomy, 18 (19.1%) total gastrectomy and 21 (22.3%) partial gastrectomy. A significant association was seen between development of complications and higher Day 5 White Cell count (WCC) (p = 0.048), lower Day 2–5 Albumin (Day 2 Albumin p = 0.038) and higher Day 2–5 C Reactive Protein (CRP) (Day 2 CRP p<0.001).
Conclusions
This study suggests Albumin, CRP and WCC may be used to predict postoperative complications in patients undergoing oesophagogastric resections for malignancy. Changes in the blood parameters present as early as day 2 postoperatively and can highlight patients who require closer monitoring, allowing earlier re-intervention if required.

Abstract
OBJECTIVE Due to the continued spread of COVID-19 and the emergence of novel mutated viral variants, families all over the world are experiencing wide-ranging stressors that threaten not only their financial well-being but also their physical and mental health. The present study assessed the association between excessive electronic media exposure of pandemic-related news and mental health of the residents of Ha'il Province, Saudi Arabia. The present study also assessed the prevalence of perceived stress, fear of COVID-19, anxiety, depression, and loneliness due to COVID-19-related restrictions in the same population. MATERIALS AND METHODS A total of 490 residents of Ha'il Province participated in a cross-sectional online survey during a two-month period (March to April 2021). A validated 38-item self-report survey was used to collect the data. RESULTS Significant associations were reported between excessive electronic media exposure and the prevalence of perceived stress (χ2=140.56; p<.001), generalized anxiety (χ2=74.55; p<.001), depression (χ2=71.58; p<.001), COVID-19-related fear (χ2=24.54; p<.001), and loneliness (χ2=11.46; p<.001). It was also found that participants without depressive symptoms were 0.28 times less likely to have been exposed to excessive electronic media exposure (AOR: 0.28; C.I. 0.16-0.48; p<.001). Similarly, participants with no stress/mild stress were 0.32 times less likely to have been exposed to excessive electronic media exposure (AOR: 0.32; C.I. 0.19-0.52; p<.001). CONCLUSIONS The findings of the present study suggest an urgent need for educational resilience programs (online and in-person) for susceptible individuals (females, unemployed, urban residents, etc.). Such programs would help them to develop skills to cope with the psychological impact of the COVID-19 pandemic.

Abstract
Abstract
Introduction
To reduce the risk of regurgitation and aspiration of gastric contents, patients are to fast before anaesthesia. However, prolonged periods of fasting have been found to be unnecessary and potentially harmful. Our aim was to compare pre-operative fasting times in trauma patients against the AAGBI (Association of Anaesthetists of Great Britain and Ireland) guidelines and highlight areas for improvement. The AAGBI recommends minimum fasting periods of:
Method
50 patients were audited in each cycle. Data were collected prospectively using questionnaires in the initial audit and by interviewing patients in the re-audit. Patients in ITU and those with dementia were excluded. Questions included fasting instructions given, time of the last meal and drink (including kind of drink), IV fluids administration. Anaesthetic notes were checked for time of induction of anaesthesia.
Results
Average time fasted for food was 17.09 hours and 9.32 hours for water. In the re-audit, average time fasted was 16.43 hours for food and 5.27 hours for water. All the patients received information as to when they could eat or drink until. None of them was told ‘midnight’.
Conclusions
Although there was an improvement, this was still beyond the guidelines. The results highlighted the importance of regularly reviewing the fasting status throughout the day in order to achieve the standard.

Abstract
Background Surgical intervention for neck of femur fractures continues to be prioritised during the Covid-19 pandemic. However, there remains a lack of clarity for clinicians during the consent process. This study quantifies additional perioperative risks for Covid-19 positive patients undergoing neck of femur fracture surgery and establishes an evidence-based framework for facilitating informed consent during the Covid-19 pandemic. Method 259 patients undergoing neck of femur fracture surgery in four hospitals at the epicentre of the United Kingdom’s first wave of Covid-19 were recruited. 51 patients were positive for Covid-19. Predefined outcomes were recorded in a 30-day postoperative period. Results Odds of intensive care admission were 4.64 times higher (95% CI 1.59-13.50, p = 0.005) and odds of 30-day mortality were 3 times higher (95% CI 1.22-7.40, p = 0.02) in Covid-19 positive patients. 74.5% of Covid-19 positive patients suffered post-operative complications. 35.3% of Covid-19 positive patients developed lower respiratory tract infection with 13.7% progressing to acute respiratory distress syndrome. 9.8% of Covid-19 positive patients experienced symptomatic thromboembolic events with a 3.9% incidence of pulmonary emboli. Conclusions The implications of Covid-19 on the informed consent process for neck of femur fracture surgery are profound. Covid-19 positive patients should be consented for increased risk of postoperative complications (including lower respiratory tract infection, acute respiratory distress syndrome and thromboembolic events), longer inpatient stay, increased frequency of intensive care admission and higher risk of mortality.

Abstract
OBJECTIVE: The current study reviewed Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) variants for their effects on infection, transmission and neutralization by vaccine-induced antibodies. MATERIALS AND METHODS: The research articles for the current study were searched over PubMed, Google Scholar, EMBASE and Web of Science online databases. The keywords used were: (("SARS-CoV-2" OR "COVID-19") AND ("mutation" OR "variant") AND ("death" OR "hospitalization" OR "infection" OR "transmission") AND ("antibody" OR "neutralize" OR "vaccine")). A total of 333 research articles were retrieved through online-database search. These articles were further scrutinized for their relevancy. Additionally, searches were performed to find the latest relevant information over Google search engine and relevant news browsers. Finally, around 35 germane articles were considered for scripting the current report. RESULTS: The mutations have changed amino acids at key positions in spike protein viz. S477N, E484K, Q677H, E484Q, L452R, K417T, K417N and N501Y. These mutations are relevant for different characteristics and are present in newly evolved strains of SARS-CoV-2 like E484K in B.1.526, B.1.525, P.2, B.1.1.7, P.1 and B.1.351. Mutations have increased the immune escape potential leading to 3.5-6.5-folds decrease in neutralization of antibodies (Pfizer and Moderna vaccines). The variant, B.1.617 circulating in India and many other countries (double variant) having E484Q and L452R mutations, has raised the infection rate and decreased the neutralization capacity of the vaccine-induced antibodies. Deadly K417N+E484K+N501Y triplet mutations found in B.1.351 and P.1 have increased the transmission ability of these strains by 50% leading to greater COVID-19 hospitalization, ICU admissions and deaths. CONCLUSIONS: The new SARS-CoV-2 variants have compromised the neutralization potential of the currently used vaccines, but still, they have considerable efficacy to reduce infection and mortality.

Abstract
BACKGROUND Photodiagnostic investigations are essential for the accurate diagnosis of abnormal cutaneous photosensitivity and provide important information for the management of patients with photodermatoses (cutaneous photosensitivity disorders). Although photodiagnosis has been undertaken since the early 1970s, specialist services in the United Kingdom (UK) and Republic of Ireland are limited and there is no formal guidance on diagnostic approach. Indeed, there is a limited literature in this area of methodology and diagnostic practice. OBJECTIVES The primary objective was to undertake a British Photodermatology Group Workshop to review the role and activities of specialist centres in the UK and Republic of Ireland in order to ascertain whether there were consensus practices. Secondary objectives were to identify key priorities for service, training and research. METHODS An initial detailed survey review of current activities was undertaken prior to the Workshop and data from this survey were used to inform discussion at the Workshop, which was attended by key photodermatology experts from the UK and Republic of Ireland. RESULTS/CONCLUSIONS We have undertaken a detailed review of current Photodiagnostic Services in the UK and Republic of Ireland and report on our findings from the 12 centres and we have identified key areas of consensus practice. This is an important step in the process of standardising and optimising procedures and protocols and defining minimum clinical standards for photodiagnostic investigations, which are of such diagnostic importance in Dermatology.

Abstract
OBJECTIVE Nitric Oxide (NO) is produced by NO synthases (NOS) and is a key signaling molecule that regulates tumorigenesis, both aiding and alleviating it. Elevated NO levels are cytotoxic to cancer cells, making NOS an important target for cancer treatment. In the present study, the modulatory effects of the phytochemicals, quercetin, sulforaphane, genistein, and epigallocatechin-3-gallate on NO pathway and apoptosis were shown in HeLa cervical cancer cells. MATERIALS AND METHODS Fluorescent microscopy and flow cytometry were used to assess apoptosis. A Griess assay was used to quantitatively measure NO, quantitative PCR array was used to assess the expression levels of genes involved in the NO signaling pathway, and immunocytochemistry was used to determine NOS protein expression. The functional association among the modulated genes was evaluated using network biology analysis, gene set enrichment, and KEGG pathway analysis. RESULTS Treatment with the phytochemicals elevated NO levels in HeLa cells and modulated various genes involved in nitric oxide biosynthesis, superoxide metabolism, and oxidative stress, including NOS1, NOS2, NOS3, ALOX12, and SOD2, with a concomitant increase in NOS2 and NOS3 protein expression levels; also, the phytochemicals were found to induce apoptosis. CONCLUSIONS These results suggest that the phytochemical-induced cell death is partially attributed to the activation of the NO pathway and upregulation of pro-oxidant ROS generators. Further experimental studies are required to explore this mechanistic association of NO signaling pathway activation and induction of apoptosis in other types of cancer.

Abstract
Abstract
Introduction
Surgical departments across the UK are having to mitigate service demands, budget constraints and changes to work patterns with their statutory duty to provide high-quality training and education. Securing consultant-led teaching has also become increasingly difficult leading to the rise of near-peer teaching. We evaluate the long-term effectiveness of near-peer surgical teaching for junior doctors.
Method
We developed a rolling 12-week trainee-led didactic surgical education programme for Foundation doctors and Core Surgical Trainees. Junior doctors delivered teaching to peers with registrar input; session and supervision feedback was recorded using 5-point scales and free-text responses.
Results
42 junior doctors responded to our end-of-programme feedback surveys covering December 2018 to April 2020. The overall programme (8.83±1.08/10), relevance (4.62±0.58/5), presentation quality (4.60±0.50/5) and supervisor knowledge (4.81±0.40/5) were rated highly by respondents. Attendees also reported significant improvements in subject knowledge (3.72±0.92/5 to 4.50±0.56/5, P < 0.0001), clinical confidence, presentation and teaching skills.
Conclusions
Our near-peer teaching programme addressed the educational needs of junior doctors and developed their presentation and organisational skills. Supervision and input from registrars facilitated discussion and reinforced key concepts. The success of this programme highlights the role that trainees can play in designing, developing, and leading an effective surgical teaching programme.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) uses Angiotensin- converting enzyme 2 (ACE2) receptors to infect host cells which may lead to coronavirus disease (COVID-19). Given the presence of ACE2 receptors in the brain and the critical role of the renin-angiotensin system (RAS) in brain functions, special attention to brain microcirculation and neuronal inflammation is warranted during COVID-19 treatment. Neurological complications reported among COVID-19 patients range from mild dizziness, headache, hypogeusia, hyposmia to severe like encephalopathy, stroke, Guillain-Barre Syndrome (GBS), CNS demyelination, infarcts, microhemorrhages and nerve root enhancement. The pathophysiology of these complications is likely via direct viral infection of the CNS and PNS tissue or through indirect effects including post- viral autoimmune response, neurological consequences of sepsis, hyperpyrexia, hypoxia and hypercoagulability among critically ill COVID-19 patients. Further, decreased deformability of red blood cells (RBC) may be contributing to inflammatory conditions and hypoxia in COVID-19 patients. Haptoglobin, hemopexin, heme oxygenase-1 and acetaminophen may be used to maintain the integrity of the RBC membrane.

Abstract
BACKGROUND Multiple factors constrain the trajectories of child cognitive development, but the drivers that differentiate the trajectories are unknown. We examine how multiple early life experiences differentiate patterns of cognitive development over the first 5 years of life in low-and middle-income settings. METHODS Cognitive development of 835 children from the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) multisite observational cohort study was assessed at 6, 15, 24 (Bayley Scales of Infant and Toddler Development), and 60 months (Wechsler Preschool and Primary Scale of Intelligence). Markers of socioeconomic status, infection, illness, dietary intake and status, anthropometry, and maternal factors were also assessed. Trajectories of development were determined by latent class-mixed models, and factors associated with class membership were examined by discriminant analysis. RESULTS Five trajectory groups of cognitive development are described. The variables that best discriminated between trajectories included presence of stimulating and learning resources in the home, emotional or verbal responsivity of caregiver and the safety of the home environment (especially at 24 and 60 months), proportion of days (0-24 months) for which the child had diarrhea, acute lower respiratory infection, fever or vomiting, maternal reasoning ability, mean nutrient densities of zinc and phytate, and total energy from complementary foods (9-24 months). CONCLUSIONS A supporting and nurturing environment was the variable most strongly differentiating the most and least preferable trajectories of cognitive development. In addition, a higher quality diet promoted cognitive development while prolonged illness was indicative of less favorable patterns of development.

Abstract
The patient with diabetes mellitus and its complication is increasing in our country and all over the world. Altered platelet morphology and function have been reported in patient with DM. Mean platelet volume has been suggested as a newly emerging and independent risk marker for atherothrombosis and cardiovascular disease. The present study was carried out to assess the mean platelet volume in subjects with type 2 diabetes mellitus. The present study was a cross sectional analytic study and conducted in the Department of Physiology, Dhaka Medical College, Dhaka, Bangladesh from July 2013 to June 2014. A total number of 200 adult male subjects were selected with age ranging from 40 to 60 years. Among them, 100 subjects with type 2 diabetes mellitus were included in the case (Group B) and 100 healthy subjects with same age range were considered as control (Group A) for comparison. The subjects were selected from BIRDEM hospital Dhaka and personal contact from different areas of Dhaka city on the basis of exclusion and inclusion criteria. The study parameter was mean platelet volume and was measured in the Department of Hematology of BIRDEM hospital, Dhaka. The data were collected and recorded in pre-designed structured questionnaire by the researcher herself. For statistical analyses unpaired Student's 't' test was performed as applicable using SPSS for windows version 19. In this study, mean platelet volume was significantly (p<0.001) higher in the case group than that of control group. Therefore, estimation of mean platelet volume might be beneficial for prediction of future cardiovascular risk in adult diabetic male.

Abstract
Background:Patients with rheumatological foot disease are an overlooked population, and it was noted locally that these patients received a fragmented service; attending multiple appointments for the management of one clinical issue. This led to delays in treatment; significant inter-departmental correspondence and variations in the peri-operative management of disease modifying anti-rheumatic drug (DMARD) and biologic therapies. To remedy this a foot multidisciplinary (MDT) clinic was established, including input from rheumatology, orthopaedic surgery, specialist rheumatology podiatry and physiotherapy. The outcomes from the foot MDT clinic have been analysed in this service evaluation project.Objectives:To evaluate the outcomes of the multidisciplinary foot MDT clinic, with particular reference to concordance to the British Rheumatology Society (BSR) guidelines on peri-operative medicine guidelines.Methods:Data was collected retrospectively across all clinics from January 2017 to February 2019. Clinic letters were obtained, and data was collected using a standardised data collection sheet. Data was collected on patient demographics, rheumatological diagnoses, treatment outcomes from the foot MDT, appropriateness of peri-operative plan and post-operative complications. No data was available on these outcomes prior to the advent of the foot MDT clinic.Results:Data from 12 clinics was analysed (n=40). Patients had a median age of 66 years (IQR 27.5 years); 65% of patients were female and 35% of patients were male. The commonest rheumatological foot disease seen was rheumatoid arthritis (67%), followed by psoriatic arthritis (15%). All patients were treated with biologic or non-biologic DMARDs. Treatment outcomes were as follows: 27.5% were offered surgical treatment; 10% were offered intra-articular (IA) injections under ultrasound guidance; 10% were offered IA injections under general anaesthetic; 25% underwent specialist rheumatology podiatry, and the remaining 30% elected for a conservative approach after careful consideration of treatment options. Of those who were offered surgical treatment, 72% of patients were provided with a peri-operative plan which accorded with British Rheumatology Society (BSR) guidelines. Of those whom underwent surgery, one patient’s surgical treatment was complicated by a post-operative infection; however, the peri-operative DMARD/biologic plan was not felt to be contributing factor.Conclusion:The foot MDT clinic provides a comprehensive review of rheumatological foot conditions, with readily available access to a full range of treatment options. Co-location of all relevant professionals allows for real-time interdepartmental communication; shared decision making between clinicians and patients; avoids multiple appointments; reduces uncertainty with peri-operative planning as well as providing a cost-effective and efficacious service. Discrepancies in the peri-operative plan for medicines arose when the treating orthopaedic surgeon was not present in clinic. In these cases, the plan for surgical treatment was made outside of this clinic, without input from the treating rheumatologist. To improve concordance with BSR peri-operative medicine guidelines, it is recommended that all treatment decisions are made during the clinic, allowing input from all relevant partners. Informal feedback from patients commended the foot MDT, this shall be formalised through further qualitative data.Disclosure of Interests:None declared

Background:The EULAR-ACR 2019 (EULAR19) classification criteria for systemic lupus erythematosus (SLE) were developed to improve the sensitivity and specificity of previous criteria. Notably, both the EULAR19 and existing SLICC-SLE 2012 (SLICC12) criteria can classify patients as having SLE by the presence of immunology and haematological abnormalities in the absence of any signs or symptoms.Objectives:To validate the EULAR19 criteria, with comparison to existing criteria, in a large cohort of patients with an established systemic autoimmune rheumatic disease (SARD).Methods:We recruited 227 adult patients who were ANA positive with ≥1 clinical feature suggestive of a SARD, from three hospitals in the North West of England. Clinician diagnosis was used as gold standard; we then applied the EULAR19, SLICC12 and the ACR-SLE 1997 (ACR97) criteria.Results:Of the 227 patients recruited, by clinician diagnosis, 89 patients (36%) had SLE, 43 (17%) primary Sjögren’s (pSS), 62 (25%) undifferentiated CTD (UCTD), 25 (10%) systemic sclerosis (SSc) and 8 (3%) an inflammatory myositis. The characteristics of these patients and the breakdown of the EULAR19 criteria are outlined in figure 1.Figure 1.Baseline characteristics and classification criteria compared across five SARD diagnoses.The sensitivity and specificity of the EULAR19 is similar to ACR97 (sensitivity 84% (95% CI 75-91%) vs. 87% (95% CI 78-93%) and specificity 78% (95% CI 70-84%) vs. 76% (95% CI 68-83%) respectively). The SLICC12 criteria by contrast are more sensitive (94% (95% CI 87-98%)) and less specific (61% (95% CI 52-69%)) in this cohort.Figure 2 illustrates patients with a clinician diagnosis of SLE or UCTD who meet each of the classification criteria. Of the 89 patients with a clinician diagnosis of SLE, 39 (44%) patients would have sufficient points to meet EULAR19 criteria on blood test results alone in the absence of clinical symptoms. Four pSS patients and 4 UCTD patients would also meet EULAR19 criteria from positive blood results alone.Figure 2.Venn diagrams illustrating patients with SLE and UCTD who meet the EULAR19, ACR97 and SLICC12 classification criteria. No criteria refers to the patients not meeting any of the three SLE classification criteria.Conclusion:These results suggest that the EULAR19 criteria perform comparably to the ACR97 criteria when applied to an established cohort of SARDs. Similar to SLICC12, it is possible to classify patients as having SLE using the EULAR19 criteria by haematological and other laboratory tests. To what extent haematological abnormalities can be potentially used as the sole ‘clinical criteria’ needs consideration.SLE n=89pSS n=43UCTD n=62SSc n=25Myositis n=8Female N (%)82 (92)42 (98)53 (85)24 (96)8 (100)Age, mean (SD) /years44 (13)52 (12)47 (13)60 (9)53 (7)Disease duration, mean (SD) /years12 (10)6 (5)5 (7)9 (11)3 (3)SLE classification criteriaEULAR SLE 2019, N (%)75 (84)10 (23)20 (32)1 (4)0ACR SLE 1997, N (%)77 (87)9 (21)21 (34)2 (8)1 (13)SLICC SLE 2012, N (%)84 (94)15 (35)33 (53)4 (16)2 (25)EULAR-ACR 2019 criteriaConstitutional, N (%)10 (11)2 (5)1 (2)01 (13)Neuropsychiatric, N (%)3 (3)01 (2)1 (4)0Mucocutaneous, N (%)71 (80)13 (30)27 (44)2 (8)2 (25)Serosal, N (%)13 (15)1 (2)2 (3)00Musculoskeletal, N (%)52 (58)14 (33)22 (35)3 (12)3 (38)Renal, N (%)30 (34)001 (4)0Haematological, N (%)44 (49)12 (28)10 (16)3 (12)0Antiphospholipid antibodies, N (%)43 (48)7 (16)17 (27)4 (16)0Low complement, N (%)48 (54)10 (23)10 (16)3 (12)1 (13)Anti-Sm, N (%)19 (21)2 (5)4 (6)1 (4)0Anti-dsDNA, N (%)50 (56)8 (19)12 (19)01 (13)Disclosure of Interests:Sarah Dyball: None declared, John Reynolds: None declared, Eoghan McCarthy: None declared, Sahena Haque: None declared, Ariane Herrick: None declared, Hector Chinoy: None declared, Ellen Bruce: None declared, Ben Parker Grant/research support from: GSK and Sanofi Genzyme, Consultant of: GSK, AstraZenaca, UCV, Abbvie, Pfizer, BMS, Celltrion, Ian N.

Abstract
Hexagonal and cubic crystals contain paired sets of internal planes that reflect the linearly polarized components of certain x rays into two separate, perpendicular directions. For the cubic crystals, two distinct crystal orientations provide the same polarization-splitting geometry. One of the orientations may have advantages for plasma spectroscopy by suppressing unwanted reflections. This paper demonstrates the two orientations with a germanium crystal and K characteristic lines from copper and zirconium.

Abstract
Pregnancy is accompanied by changes in the maternal lipoprotein metabolism that may serve to satisfy the nutritional demands of the fetus in addition to the energy requirements of the mother. Early pregnancy is considered the anabolic phase, characterized by increased hepatic production of triglycerides and enhanced removal of triglycerides from the circulation, resulting in an increased deposition of fat in maternal adipose tissue. Late pregnancy is referred to as the catabolic phase, the release of free fatty acids from adipocytes is enhanced due to both relative insulin resistance and stimulation of hormones. Although it is known that cholesterol rises in pregnancy, at present it is not routinely measured or treated. However, a growing body of evidence from animal and human studies suggests adverse consequences of high cholesterol levels in pregnancy. High lipid profile, a major factor behind atherosclerosis may leads to unconsciousness. To avoid such problems during pregnancy this longitudinal study was carried out in the department of Biochemistry, Mymensingh Medical College in co-operation with the Department of Obstetrics and Gynecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh from July 2011 to December 2012 to compare the changes in high density lipoprotein cholesterol level during 2nd and 3rd trimester of pregnancy. A total of one hundred subjects were participated in this study comprising of second and third trimester of pregnancy. All subjects were made to fast overnight at least for a minimum of 8 hours. Blood samples were taken and analyzed by enzymatic colorimetric kit method. Pregnancy has been found to be associated with changes in lipid profile and this differs with each trimester. The average results were analyzed with respect to each pregnancy for the whole group. The study proves that serum High Density Lipoprotein (HDL) cholesterol increases in second trimester (48.71±7.61mg/dl) than third trimester (47.01±7.45mg/dl) of Pregnancy. So, Lipid profile estimation and monitoring should be made as a part of routine investigation during antenatal period.

Abstract
BACKGROUND Child cognitive development is influenced by early-life insults and protective factors. To what extent these factors have a long-term legacy on child development and hence fulfillment of cognitive potential is unknown. OBJECTIVE The aim of this study was to examine the relation between early-life factors (birth to 2 y) and cognitive development at 5 y. METHODS Observational follow-up visits were made of children at 5 y, previously enrolled in the community-based MAL-ED longitudinal cohort. The burden of enteropathogens, prevalence of illness, complementary diet intake, micronutrient status, and household and maternal factors from birth to 2 y were extensively measured and their relation with the Wechsler Preschool Primary Scales of Intelligence at 5 y was examined through use of linear regression. RESULTS Cognitive T-scores from 813 of 1198 (68%) children were examined and 5 variables had significant associations in multivariable models: mean child plasma transferrin receptor concentration (β: -1.81, 95% CI: -2.75, -0.86), number of years of maternal education (β: 0.27, 95% CI: 0.08, 0.45), maternal cognitive reasoning score (β: 0.09, 95% CI: 0.03, 0.15), household assets score (β: 0.64, 95% CI: 0.24, 1.04), and HOME child cleanliness factor (β: 0.60, 95% CI: 0.05, 1.15). In multivariable models, the mean rate of enteropathogen detections, burden of illness, and complementary food intakes between birth and 2 y were not significantly related to 5-y cognition. CONCLUSIONS A nurturing home context in terms of a healthy/clean environment and household wealth, provision of adequate micronutrients, maternal education, and cognitive reasoning have a strong and persistent influence on child cognitive development. Efforts addressing aspects of poverty around micronutrient status, nurturing caregiving, and enabling home environments are likely to have lasting positive impacts on child cognitive development.

Abstract
Chronic otitis media is a common condition seen in patients attending the otorhinolaryngology Department. The discharging ear presents the otologists with the dilemma of operating on it or not. The aim of the this cross-sectional observational study was to find out the outcome of surgery in chronic inactive mucosal otitis media and was conducted on 62 patients of either sex in the age group of 15-60 years in the Department of ENT and Head Neck surgery, Shaheed Suhrawardy Medical College Hospital (ShSMCH), Dhaka, Bangladesh From July 2015 to January 2016. Pre and post operative hearing assessment was done with pure tone audiometry (PTA). Post operative graft status also noted. All the information's were recorded in the fixed protocol. Collected data were classified, edited, coded and entered into the computer for statistical analysis by using updated computerized program SPSS-19. Among 62 cases the mean age were 36.79±10.33 in chronic inactive mucosal otitis media. Majority of the study population were in age group of between 15-25 in this group of which was 16(51.6%). Male were 36(58.06) and 26(41.94) were female. All patients presented with history of otorrhoea in this group, 52(83.87%) had hearing impairment in chronic inactive mucosal otitis media, 30(48.39%) involved in right ear and 26(41.94%) involved in left ear and 06(9.68%) in both ear in chronic inactive mucosal otitis media. Majority of perforation were medium in size in this group of which was 30(48.39%). anterior perforation was 24(38.71%), posterior perforation 28(45.16%) and subtotal 10(16.13%) in chronic inactive mucosal otitis media. Sixty two (100%) cases underwent myringoplasty. Post-auricular approach used in most of operation in this group of which was 60(96.77%). Preoperative air conduction threshold 32(51.61%) were in between 31-45 dB in myringoplasty group (p<0.05) that was statistically significant. Postoperative air conduction threshold 30(48.39%) were between 16-30 dB in myringoplasty group (p<0.05) that was statistically significant. Difference between preoperative and postoperative air conduction threshold mean difference was 11.38 dB and 36.75±5.84 and 25.37±7.46 respectively (p<0.001) in myringoplasty group. Hearing gain was 42(67.74%) in myringoplasty (p>0.05) that was not statistically significant. Graft uptake in myringoplasty was 52(83.9%). Graft failure in myringoplasty was 10(16.1%). post operative complication was tinnitus in 12(19.35%) cases in myringoplasty. Success rate was more in case of posterior perforation than anterior and subtotal perforation in both chronic inactive mucosal otitis media which was 92.86%. Success rate was more in case of medium size perforation than subtotal perforation in chronic inactive mucosal otitis media which was 86.67%. Success rate was (100%) in small perforation in this group. From this study it can be concluded that myringoplasty is a valid treatment modality for chronic inactive mucosal otitis media to achieve an intact tympanic membrane and to gain hearing.

Abstract
Background Activating events along the PI3K/mTOR pathway are common in head and neck squamous cell carcinomas (HNSCC), and preclinical studies suggest additive or synergistic effects when combining mTORC1 inhibitors with carboplatin and paclitaxel chemotherapy. Patients and methods In this single-institution phase II study, the combination of temsirolimus 25 mg, carboplatin AUC 1.5, and paclitaxel 80 mg/m2 administered on days 1 and 8 of a 21-day cycle was evaluated in 36 patients with recurrent and/or metastatic (R/M) HNSCC. The primary end point was objective response rate after two cycles of treatment. Secondary end points include the safety and tolerability profile and overall survival. Correlative studies with exome mutational analysis were performed in pre-treatment biopsy samples from 21 patients. Results Fifteen (41.7%) patients had an objective response, which were all partial responses, and 19 (52.3%) patients had stable disease as best response. The two patients who were designated as 'non-responders' were removed from study prior to two cycles of treatment, but are included in the efficacy and safety analyses. The median duration on study was 5.3 months and the median progression-free survival and overall survival were 5.9 months (95% confidence interval, 4.8-7.1) and 12.8 months (95% confidence interval, 9.8-15.8), respectively. The most common grade 3 and 4 adverse events were hematologic toxicities. Three (3.8%) patients developed neutropenic fever on study. Three of four patients with PIK3CA mutations experienced tumor regressions, and responses were also seen in patients with other genetic alterations in the PI3K/mTOR pathway. Conclusion The combination of temsirolimus with low-dose weekly carboplatin and paclitaxel appears to have meaningful clinical efficacy in the treatment of R/M HNSCC. This regimen has a relatively high response rate compared to other treatments evaluated in R/M HNSCC, and potential associations with genetic alterations in the PI3K/mTOR pathway should be further explored.

Abstract
A recently developed single-crystal x-ray spectropolarimeter has been used to record paired sets of polarization-dependent and axially resolved x-ray spectra emitted by wire array z-pinches. In this measurement, two internal planes inside a suitable crystal diffract the x-rays into two perpendicular directions that are normal to each other, thereby separating incident x-rays into their linearly polarized components. This paper gives considerations for fielding the instrument on extended sources. Results from extended sources are difficult to interpret because generally the incident x-rays are not separated properly by the crystal. This difficulty is mitigated by using a series of collimating slits to select incident x-rays that propagate in a plane of symmetry between the polarization-splitting planes. The resulting instrument and some of the spatially resolved polarized x-ray spectra recorded for a 1-MA aluminum wire array z-pinch at the Nevada Terawatt Facility at the University of Nevada, Reno will be presented.

Abstract
Identification of dematiaceous fungi responsible for black-grain mycetoma has remained cumbersome and time consuming for years leading to delayed diagnosis and thereby increased agony to patients. Moreover, difficult morphology of some of these fungi demanding enough expertise for species identification in addition to culture-negativity has often led to misdiagnosis and hence inapt treatment to the patients. We report the identification of Madurella mycetomatis from culture-negative black granules discharged from foot nodular lesions of a 27 years old male using PCR followed by sequencing of the internal transcribed spacer region. The patient's lesions were successfully treated using a combination of itraconazole (200mg) and terbinafine (250mg), confirming our diagnosis. Our case study proves the clinical value of PCR as the best, rapid and accurate diagnostic method for the identification of Madurella mycetomatis and related fungi, particularly in culture-negative cases.

Abstract
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67P/Churyumov-Gerasimenko from before Rosetta's arrival until nearly the end of the mission in September 2016. These provided essential data for mission planning, large-scale context information for the coma and tails beyond the spacecraft and a way to directly compare 67P with other comets. The observations revealed 67P to be a relatively 'well-behaved' comet, typical of Jupiter family comets and with activity patterns that repeat from orbit to orbit. Comparison between this large collection of telescopic observations and the in situ results from Rosetta will allow us to better understand comet coma chemistry and structure. This work is just beginning as the mission ends-in this paper, we present a summary of the ground-based observations and early results, and point to many questions that will be addressed in future studies.This article is part of the themed issue 'Cometary science after Rosetta'.

Abstract
Breast cancer is the most common malignancy in women and the second most common cause of cancer-related mortality. The distinction by physical examination of physiologic nodularity from abnormal masses can be difficult, while the clinical differentiation of a malignant mass from a benign one is difficult; the medical as well as potential legal consequences of missing a palpable carcinoma are high. There are significant number of reported cases of false-negative findings on mammography and the great desire not to miss a malignant lesion in the early stage of disease lead to aggressive biopsy, but the biopsy rate for cancer is only 10.0% to 30.0%. This means that 70.0% to 90.0% of breast biopsies are performed for benign diseases, which induce unnecessary patients discomfort and anxiety in addition to increasing costs to the patient. Clearly, there is a great need for development of additional reliable methods to complement the existing diagnostic procedures to avoid unnecessary biopsy. This cross sectional study was carried out on 43 patients having palpable breast mass, attended in the Department of Radiology and Imaging Mymensingh Medical College Hospital, Mymensingh from 1st January 2012 to 31st December 2013 for the period of two year. These patients were evaluated by USG at the Department of Radiology and Imaging and histopathological examination at the Department of Pathology of the same College to confirm the diagnosis. In diagnosis of malignant mass by USG, 9(20.9%) cases were diagnosed as malignant and 34(79.1%) cases as other than malignant. Eight out of 9 were sonographically diagnosed as malignant lesions also proved as malignant lesion by histopathology and 1 other than malignant. Out of 34 sonographically diagnosed cases of other than malignant lesions 32 were proved histopathologically and 2 did not match with sonographic findings. USG, in diagnosis of malignant lesion, sensitivity was 80.0%, specificity 96.97%, positive predictive value (PPV) (88.89%), negative predictive value 94.12% and accuracy was 93.02% and comparable to other study. In diagnosis of benign lesion by USG, sensitivity was 96.97%, specificity 80.0%, positive predictive value (PPV) (94.12%), negative predictive value 88.89% and accuracy was 93.02%. So, USG is an appropriate imaging method for diagnosis & differential diagnosis of palpable breast mass.

Abstract
Spectroscopic techniques in the visible range are often used in plasma experiments to measure B-field induced Zeeman splitting, electron densities via Stark broadening, and temperatures from Doppler broadening. However, when electron densities and temperatures are sufficiently high, the broadening of the Stark and Doppler components can dominate the emission spectra and obscure the Zeeman component. In this research, we are developing a time-resolved multi-axial technique for measuring the Zeeman, Stark, and Doppler broadened line emission of dense magnetized plasmas for Z-pinch and Dense Plasma Focus (DPF) accelerators. The line emission is used to calculate the electron densities, temperatures, and B-fields. In parallel, we are developing a line-shape modeling code that incorporates the broadening effects due to Stark, Doppler, and Zeeman effects for dense magnetized plasma. This manuscript presents the details of the experimental setup and line shape code, along with the results obtained from an Al iii doublet at the University of Nevada, Reno at Nevada Terawatt Facility. Future tests are planned to further evaluate the technique and modeling on other material wire array, gas puff, and DPF platforms.

Abstract
Altered metabolic and hormonal status of the body in pregnancy leads to changes in lipid profile. High Lipid profile, a major factor behind atherosclerosis may leads to unconsciousness. To avoid such problems during pregnancy this longitudinal study was carried out in the Department of Biochemistry, Mymensingh Medical College in co-operation with the Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh during the period from July 2011 to December 2012 to compare the changes in low density lipoprotein cholesterol level during 2nd and 3rd trimester of pregnancy. A total of one hundred subjects were participated in this study comprising of second and third trimester of pregnancy. All subjects were made to fast overnight at least for a minimum of 8 hrs. Blood samples were taken and analyzed by enzymatic colorimetric kit method. Pregnancy has being found to be associated with changes in lipid profile and this differs with each trimester. The average results were analyzed with respect to each pregnancy for the whole group. The study proves that serum Low Density Lipoprotein (LDL) cholesterol increases in third trimester (174.83±13.78 mg/dl) than second trimester (156.77±7.96 mg/dl) of pregnancy. Therefore, lipid profile estimation and monitoring should be made as a part of routine investigation during antenatal period.

Abstract
BACKGROUND Recurrent/metastatic adenoid cystic carcinoma (ACC) is an incurable disease with no standard treatments. The majority of ACCs express the oncogenic transcription factor MYB (also c-myb), often in the context of a MYB gene rearrangement. This phase II trial of the tyrosine kinase inhibitor (TKI) axitinib (Pfizer) tested the hypothesis that targeting pathways activated by MYB can be therapeutically effective for ACC. PATIENTS AND METHODS This is a minimax two-stage, phase II trial that enrolled patients with incurable ACC of any primary site. Progressive or symptomatic disease was required. Patients were treated with axitinib 5 mg oral twice daily; dose escalation was allowed. The primary end point was best overall response (BOR). An exploratory analysis correlating biomarkers to drug benefit was conducted, including next-generation sequencing (NGS) in 11 patients. RESULTS Thirty-three patients were registered and evaluable for response. Fifteen patients had the axitinib dose increased. Tumor shrinkage was achieved in 22 (66.7%); 3 (9.1%) had confirmed partial responses. Twenty-five (75.8%) patients had stable disease, 10 of whom had disease stability for >6 months. The median progression-free survival (PFS) was 5.7 months (range 0.92-21.8 months). Grade 3 axitinib-related toxicities included hypertension, oral pain and fatigue. A trend toward superior PFS was noted with the MYB/NFIB rearrangement, although this was not statistically significant. NGS revealed three tumors with 4q12 amplification, producing increased copies of axitinib-targeted genes PDGFR/KDR/KIT. Two 4q12 amplified patients achieved stable disease for >6 months, including one with significant tumor reduction and the longest PFS on study (21.8 months). CONCLUSIONS Although the primary end point was not met, axitinib exhibited clinical activity with tumor shrinkage achieved in the majority of patients with progressive disease before trial enrollment. Analysis of MYB biomarkers and genomic profiling suggests the hypothesis that 4q12 amplified ACCs are a disease subset that benefit from TKI therapy.

Abstract
BACKGROUND AND PURPOSE Diffuse intrinsic pontine gliomas are inoperable high-grade gliomas with a median survival of less than 1 year. Convection-enhanced delivery is a promising local drug-delivery technique that can bypass the BBB in diffuse intrinsic pontine glioma treatment. Evaluating tumor response is critical in the assessment of convection-enhanced delivery of treatment. We proposed to determine the potential of 3D multivoxel (1)H-MR spectroscopy to evaluate convection-enhanced delivery treatment effect in these tumors. MATERIALS AND METHODS We prospectively analyzed 3D multivoxel (1)H-MR spectroscopy data for 6 patients with nonprogressive diffuse intrinsic pontine gliomas who received convection-enhanced delivery treatment of a therapeutic antibody (Phase I clinical trial NCT01502917). To compare changes in the metabolite ratios with time, we tracked the metabolite ratios Cho/Cr and Cho/NAA at several ROIs: normal white matter, tumor within the convection-enhanced delivery infusion site, tumor outside of the infused area, and the tumor average. RESULTS There was a comparative decrease in both Cho/Cr and Cho/NAA metabolite ratios at the tumor convection-enhanced delivery site versus tumor outside the infused area. We used MR spectroscopy voxels with dominant white matter as a reference. The difference between changes in metabolite ratios became more prominent with increasing time after convection-enhanced delivery treatment. CONCLUSIONS The comparative change in metabolite ratios between the convection-enhanced delivery site and the tumor site outside the infused area suggests that multivoxel (1)H-MR spectroscopy, in combination with other imaging modalities, may provide a clinical tool to accurately evaluate local tumor response after convection-enhanced delivery treatment.

Abstract
Abstract
Introduction: Targeted therapies in HER2+ MBC significantly improve outcomes but efficacy is limited by therapeutic resistance. HSP90 is a molecular chaperone involved in the stability and function of multiple signaling onco-proteins. HER2 is an acutely sensitive HSP90 client and HSP90 inhibition can overcome trastuzumab resistance. Our group reported objective responses with 17-AAG plus trastuzumab in HER2+ MBC. Ganetespib, a synthetic, second generation HSP90 inhibitor has increased potency and tolerability compared with earlier agents. We reported anti-tumor activity in metastatic HER2+ and triple negative breast cancer with single agent ganetespib. Preclinically, HSP90 inhibition has synergistic anti-tumor activity with taxanes and trastuzumab. This study will define the MTD and RP2D of ganetespib plus paclitaxel and trastuzumab in HER2+ MBC.
Methods: In this 3+3 phase I dose escalation study, patients with trastuzumab-resistant HER2+ MBC receive weekly trastuzumab and paclitaxel (80mg/m2) with ganetespib on day 1, 8, 15 of a 28 day cycle. HR+ positive patients are required to have at least one prior line of endocrine therapy. DLT of ganetespib monotherapy is diarrhea and therefore patients receive prophylactic anti-motility agents. Based on prior experience with ganetespib plus docetaxel in NSCLC, only 3 dose levels of ganetespib were explored: 100mg/m2, 150mg/m2 and a 3rd cohort of 125mg/m2, if needed. Secondary endpoints include evaluation of effects of ganetespib on the pharmacokinetics (PK) of paclitaxel and preliminary efficacy assessment.
Results: The dosing cohorts (100 mg/m2 (n=3) and 150 mg/m2 (n=6)) have been completed without any DLTs. Median age was 46 years (range 29-65), median prior lines of chemotherapy and anti-HER2 therapy were 3 (range 2-6) and 3 (range 2-4) respectively, including prior pertuzumab in 9/9 and T-DM1 in 8/9 patients. There were no grade 3/4 adverse events (AEs) related to ganetespib. Most common AEs related to ganetespib were diarrhea, fatigue, anemia and rash. Paclitaxel PK data available from 6/9 patients are not appreciably different from those reported in literature. Overall response rate was 25% (2/8 had PR in 150 mg/m2 cohort; 1 patient was not evaluable), SD in 63% (5/8), and clinical benefit rate (CR+PR+SD>24 weeks) was 50% (4/8). 3 patients remain on study.
Conclusion: The RP2D of ganetespib is 150mg/m2 in combination with paclitaxel and trastuzumab. The combination was safe and well tolerated. Updated PFS and PK data will be presented. Despite prior taxanes, pertuzumab and T-DM1, clinical activity of this triplet regimen in this heavily pre-treated cohort is very promising and together with our prior experience with 17-AAG plus trastuzumab and single agent ganetespib warrants further study in HER2+ MBC. A phase 2 trial is being planned in trastuzumab-refractory HER2+ MBC who have progressed on prior pertuzumab and T-DM1. Additionally, the protocol is amended to assess the safety of ganetespib in combination with paclitaxel, trastuzumab and pertuzumab in the first-line setting.

Abstract
BACKGROUND Lower-limb immobilization has been implicated as an etiologic factor for a venous thromboembolism (VTE). Most of the current literature encourages the use of thromboprophylaxis with injectable low-molecular-weight heparin (LMWH) in trauma patients. Injectable anticoagulants have inherent problems of producing pain and bruising. They are also difficult to administer, leading to low compliance. Oral anticoagulants are therefore gaining popularity for use as thromboprophylactic agents in hip and knee arthroplasty patients. There are not enough studies in the literature, however, to support their use in ambulatory trauma patients whose ankle fractures are being managed nonoperatively on an outpatient basis. METHODS This study evaluated the efficacy of oral anticoagulants for preventing VTE in ambulatory trauma patients who required temporary lower limb immobilization for non-operative management of their ankle fractures. A total of 200 consecutive patients who presented to the fracture clinic with an ankle fracture that was managed in a plaster cast were included in this study. These patients were assessed for risk of developing VTE and high risk patients were administered an oral anticoagulant to prevent VTE. RESULTS There was only one case of an isolated distal DVT among the 200 patients. CONCLUSIONS This study shows that an oral anticoagulant was a safe alternative to injectable LMWH as a thromboprophylactic agent for ambulatory trauma patients requiring temporary lower limb immobilization for non-operative management of an ankle fracture.

Abstract
This prospective randomized study was carried out in the department of Radiology and Imaging in collaboration with the department of Obstetrics and Gynecology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag and Dhaka Medical College Hospital (DMCH) during the period of January 2003 to December 2004. The aim of this study was to establish sonohyterography as a sensitive tool and superior to Transvaginal Sonography (TVS) for detection of endometrial pathology in women with abnormal uterine bleeding (AUB) and its validity by determining sensitivity, specificity, accuracy, positive predictive value and negative predictive value. For this purpose, a total number of 40 patients who had thickened endometrium (cut off level <15 mm for pre menopausal and <5 mm for post menopausal patients) detected on transabdominal or transvaginal sonography were selected. TVS and TV-SH were done in all these patients and findings were then compared with the final histopathological diagnosis. In our study, we found TV-SH has sensitivity of 100%, specificity of 80% and accuracy of 97.5 % compared to TVS (94 %, 66.66 % and 90 % respectively) in detection of endometrial pathology in women with AUB. TV-SH can thus be regarded as one of the most sensitive, specific and accurate modality in detecting and excluding endoluminal masses as the cause of AUB. It can be considered as the initial examination in the evaluation of all women with AUB. DOI: http://dx.doi.org/10.3329/bmrcb.v40i1.20322 Bangladesh Med Res Counc Bull 2014; 40: 10-14
