Abstract
Increased hyperphosphorylated tau and the formation of intracellular neurofibrillary tangles are associated with the loss of neurons and cognitive decline in Alzheimer's disease, and related neurodegenerative conditions. We applied two diffusion models, diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI), to in vivo diffusion magnetic resonance images (dMRI) of a mouse model of human tauopathy (rTg4510) at 8.5 months of age. In grey matter regions with the highest degree of tau burden, microstructural indices provided by both NODDI and DTI discriminated the rTg4510 (TG) animals from wild type (WT) controls; however only the neurite density index (NDI) (the volume fraction that comprises axons or dendrites) from the NODDI model correlated with the histological measurements of the levels of hyperphosphorylated tau protein. Reductions in diffusion directionality were observed when implementing both models in the white matter region of the corpus callosum, with lower fractional anisotropy (DTI) and higher orientation dispersion (NODDI) observed in the TG animals. In comparison to DTI, histological measures of tau pathology were more closely correlated with NODDI parameters in this region. This in vivo dMRI study demonstrates that NODDI identifies potential tissue sources contributing to DTI indices and NODDI may provide greater specificity to pathology in Alzheimer's disease. We analyzed the microstructural changes in rTg4510 and wild type mice at 8.5 months. We correlated microstructural findings with histological measures of tau burden We compare two diffusion MR models: DTI and NODDI. Both models revealed changes in tissue microstructure due to tau pathology. The NODDI metrics demonstrated a good correlation with histological measures of tau burden.

Abstract
Intron retention in transcripts and the presence of 5' and 3' splice sites within these introns mediate alternate splicing, which is widely observed in animals and plants. Here, functional characterisation of the K(+) transporter, HvHKT2;1, with stably retained introns from barley (Hordeum vulgare) in yeast (Saccharomyces cerevisiae), and transcript profiling in yeast and transgenic tobacco (Nicotiana tabacum) is presented. Expression of intron-retaining HvHKT2;1 cDNA (HvHKT2;1-i) in trk1, trk2 yeast strain defective in K(+) uptake restored growth in medium containing hygromycin in the presence of different concentrations of K(+) and mediated hypersensitivity to Na(+) . HvHKT2;1-i produces multiple transcripts via alternate splicing of two regular introns and three exons in different compositions. HKT isoforms with retained introns and exon skipping variants were detected in relative expression analysis of (i) HvHKT2;1-i in barley under native conditions, (ii) in transgenic tobacco plants constitutively expressing HvHKT2;1-i, and (iii) in trk1, trk2 yeast expressing HvHKT2;1-i under control of an inducible promoter. Mixed proportions of three HKT transcripts: HvHKT2;1-e (first exon region), HvHKT2;1-i1 (first intron) and HvHKT2;1-i2 (second intron) were observed. The variation in transcript accumulation in response to changing K(+) and Na(+) concentrations was observed in both heterologous and plant systems. These findings suggest a link between intron-retaining transcripts and different splice variants to ion homeostasis, and their possible role in salt stress.

Abstract
As the number of people diagnosed with Alzheimer's disease (AD) reaches epidemic proportions, there is an urgent need to develop effective treatment strategies to tackle the social and economic costs of this fatal condition. Dozens of candidate therapeutics are currently being tested in clinical trials, and compounds targeting the aberrant accumulation of tau proteins into neurofibrillary tangles (NFTs) are the focus of substantial current interest. Reliable, translatable biomarkers sensitive to both tau pathology and its modulation by treatment along with animal models that faithfully reflect aspects of the human disease are urgently required. Magnetic resonance imaging (MRI) is well established as a valuable tool for monitoring the structural brain changes that accompany AD progression. However the descent into dementia is not defined by macroscopic brain matter loss alone: non-invasive imaging measurements sensitive to protein accumulation, white matter integrity and cerebral haemodynamics probe distinct aspects of AD pathophysiology and may serve as superior biomarkers for assessing drug efficacy. Here we employ a multi-parametric array of five translatable MRI techniques to characterise the in vivo pathophysiological phenotype of the rTg4510 mouse model of tauopathy (structural imaging, diffusion tensor imaging (DTI), arterial spin labelling (ASL), chemical exchange saturation transfer (CEST) and glucose CEST). Tau-induced pathological changes included grey matter atrophy, increased radial diffusivity in the white matter, decreased amide proton transfer and hyperperfusion. We demonstrate that the above markers unambiguously discriminate between the transgenic group and age-matched controls and provide a comprehensive profile of the multifaceted neuropathological processes underlying the rTg4510 model. Furthermore, we show that ASL and DTI techniques offer heightened sensitivity to processes believed to precede detectable structural changes and, as such, provides a platform for the study of disease mechanisms and therapeutic intervention.

Abstract
BACKGROUND Laparoscopic hernia repair is used widely for the repair of incisional hernias. Few case studies have focussed on purely 'incisional' hernias. This multicentre series represents a collaborative effort and employed statistical analyses to provide insight into the factors predisposing to recurrence of incisional hernia after laparoscopic repair. A specific hypothesis (ie, laterality of hernias as well as proximity to the xyphoid process and pubic symphysis predisposes to recurrence) was also tested. METHODS This was a retrospective study of all laparoscopic incisional hernias undertaken in six centres from 1 January 2004 to 31 December 2010. It comprised a comprehensive review of case notes and a follow-up using a structured telephone questionnaire. Patient demographics, previous medical/surgical history, surgical procedure, postoperative recovery, and perceived effect on quality of life were recorded. Repairs undertaken for primary ventral hernias were excluded. A logistic regression analysis was then fitted with recurrence as the primary outcome. RESULTS A total of 186 cases (91 females) were identified. Median follow-up was 42 months. Telephone interviews were answered by 115/186 (62%) of subjects. Logistic regression analyses suggested that only female sex (odds ratio (OR) 3.53; 95% confidence interval (CI) 1.39-8.97) and diabetes mellitus (3.54; 1-12.56) significantly increased the risk of recurrence. Position of the defect had no statistical effect. CONCLUSIONS These data suggest an increased risk of recurrence after laparoscopic incisional hernia repair in females and subjects with diabetes mellitus. These data will help inform surgeons and patients when considering laparoscopic management of incisional hernias. We recommend a centrally hosted, prospectively maintained national/international database to carry out additional research.

Abstract
We aimed to assess the bioaccumulation of selected four trace metals (Cd, Ni, Zn and Co) in four tissues (muscles, skin, gills and liver) of a freshwater fish Wallago attu (lanchi) from three different sites (upstream, middle stream and downstream) of the Indus River in Mianwali district of Pakistan. Heavy metal contents in water samples and from different selected tissues of fish were examined by using flame atomic absorption spectrometry. The data were statistically compared to study the effects of the site and fish organs and their interaction on the bioaccumulation pattern of these metals at P < 0.05. In W. attu the level of cadmium ranged from 0.004 to 0.24; nickel 0.003–0.708; cobalt 0.002–0.768 and zinc 47.4–1147.5 μg/g wet weight. The magnitude of metal bioaccumulation in different organs of fish species had the following order gills > liver > skin > muscle. The order of bioaccumulation of these metals was Ni < Zn < Co < Cd. Heavy metal concentrations were increased during the dry season as compared to the wet season. The results of this study indicate that freshwater fish produced and marketed in Mianwali have concentrations below the standards of FEPA/WHO for these toxic metals.

Abstract
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg^{2} patch of sky centered on RA 0 h, Dec. -57.5°. The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polarization at seven frequencies from 30 to 353 GHz, but much less deeply in any given region (1.2 μK deg in Q and U at 143 GHz). We detect 150×353 cross-correlation in B modes at high significance. We fit the single- and cross-frequency power spectra at frequencies ≥150 GHz to a lensed-ΛCDM model that includes dust and a possible contribution from inflationary gravitational waves (as parametrized by the tensor-to-scalar ratio r), using a prior on the frequency spectral behavior of polarized dust emission from previous Planck analysis of other regions of the sky. We find strong evidence for dust and no statistically significant evidence for tensor modes. We probe various model variations and extensions, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint. Finally, we present an alternative analysis which is similar to a map-based cleaning of the dust contribution, and show that this gives similar constraints. The final result is expressed as a likelihood curve for r, and yields an upper limit r_{0.05}<0.12 at 95% confidence. Marginalizing over dust and r, lensing B modes are detected at 7.0σ significance.

Abstract
A study of the levels of six pesticide residues (endosulfan, carbofuran, cypermethrin, profenofos, triazophos, and deltamethrin) was conducted to determine possible environmental and health risks in surface waters, sediment, and fish Catla catla. Samples were analyzed by gas chromatography with an electron capture detector. The total concentration of pesticides in water, sediment, and fish ranged from 0.005 to 3.17 μg/l, 0.61 to 23.06 ng/g dry weight, and 0.35 to 19.15 μg/g lipid-normalized units, respectively. According to the concentrations and detection frequencies, endosulfan and profenofos were the most dominant pesticides recorded in fish tissue and sediment samples. Profenofos and cypermethrin, meanwhile, were the most abundant pesticides recorded in water samples at these sites. Cypermethrin and triazophos were not detected in the sediment samples. The concentration of endosulfan, carbofuran, and deltamethrin were higher than the permissible limits for fish set by international agencies and pose a potential ecological risk to the aquatic ecosystem and a consequent hazard to human health.

Abstract
Successful disease management requires a rapid and sensitive diagnosis method that can recognize early infection even before the manifestation of its clinical signs. The only available field diagnostic tests for foot-and-mouth disease (FMD) are lateral flow devices, commonly known as chromatographic strips. Low sensitivity and inability to detect FMD virus (FMDV) at the serotype level are limitations of lateral flow devices. Therefore, a reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) was standardized using universal and sero-type specific genes in a single tube. This test does not require sophisticated equipment and can detect FMDV at serotype level in about 60 min. In addition, the sensitivity and specificity of this test is comparable to conventional reverse transcriptase PCR and real time PCR (rRT-PCR).

Abstract
Dengue is the fastest emerging arboviral infection and became a major public health concern in tropical and subtropical countries. Dengue infections can result in a wide spectrum of disease severities ranging between dengue fever (DF) to the life-threatening dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). This study was performed to find out the varied presentations and laboratory findings to put forward an overview about dengue syndrome in Bangladesh, in order to create better awareness and diagnostic skills among the health care providers. This hospital based observational study was conducted in the department of Medicine, Square Hospitals Ltd. during January, 2008 to December, 2010. A total of 262 adult subjects of both sexes having dengue syndrome were included in this study. Dengue syndrome was common in younger age group and the majority (72%) was below 45 years of age. All the patients had fever and the majority had malaise (96%), severe headache (72%) and musculoskeletal pain (65%). Skin rash (47%) was the commonest hemorrhagic manifestation while tourniquet test (49%) and low pulse pressure (37%) were the commonest clinical signs. All had thrombocytopenia (100%) and the majority had leukopenia (84%) and elevated liver transaminase (ALT-74%, AST-88%). Most of the subjects developed anti dengue antibody (IgM-92%, IgG -72%). All subjects survived.

Abstract
We studied simultaneously the (4)He(e,e'p), (4)He(e,e'pp), and (4)He(e,e'pn) reactions at Q(2)=2(GeV/c)(2) and x(B)>1, for an (e,e'p) missing-momentum range of 400 to 830 MeV/c. The knocked-out proton was detected in coincidence with a proton or neutron recoiling almost back to back to the missing momentum, leaving the residual A=2 system at low excitation energy. These data were used to identify two-nucleon short-range correlated pairs and to deduce their isospin structure as a function of missing momentum, in a region where the nucleon-nucleon (NN) force is expected to change from predominantly tensor to repulsive. The abundance of neutron-proton pairs is reduced as the nucleon momentum increases beyond ∼500 MeV/c. The extracted fraction of proton-proton pairs is small and almost independent of the missing momentum. Our data are compared with calculations of two-nucleon momentum distributions in (4)He and discussed in the context of probing the elusive repulsive component of the NN force.

Abstract
BACKGROUND AND AIMS The most frequent concern of patients receiving epidural analgesia for labour pain relief is post-partum back pain. This survey was designed to assess the prevalence of post-partum backache with and without epidural analgesia among post-partum women. METHODS The study was conducted at a university teaching hospital and women presenting to labour room for labour and delivery formed the target population. A total of 482 women were recruited during the study period. Response rate was 95.4% and these cases were included in our statistical analysis. Two forms were designed for data collection before and after delivery; form I was filled by one of the investigators while form II was filled by a research assistant to prevent bias which included follow-up of back pain. The primary outcome variable was backache quantified with visual analogue scale score. Out of 460 women, 230 women received epidural analgesia for labour and 230 women had not. RESULTS The prevalence of post-partum back pain in epidural analgesia versus non epidural analgesia groups was 40.9% versus 40% on day one and 32.2% versus 35.2% after 1 week. However, after one and 3(rd) months follow-up, backache prevalence was less in epidural analgesia group (unadjusted odds ratio [OR]: 0.63; 95% confidence interval [CI]: 0.39-0.99) and (unadjustedd OR: 0.32; 95% CI: 0.15-0.69) respectively. The adjusted odd ratio was 0.59 at 1st month and 0.25 at 3rd month. There was no significant difference between the two groups in pain scores. CONCLUSION There was no association between the epidural analgesia and post-partum back pain.

Abstract
We report results of a search for weakly interacting massive particles (WIMPS) with the silicon detectors of the CDMS II experiment. This blind analysis of 140.2 kg day of data taken between July 2007 and September 2008 revealed three WIMP-candidate events with a surface-event background estimate of 0.41(-0.08)(+0.20)(stat)(-0.24)(+0.28)(syst). Other known backgrounds from neutrons and 206Pb are limited to <0.13 and <0.08 events at the 90% confidence level, respectively. The exposure of this analysis is equivalent to 23.4 kg day for a recoil energy range of 7-100 keV for a WIMP of mass 10 GeV/c2. The probability that the known backgrounds would produce three or more events in the signal region is 5.4%. A profile likelihood ratio test of the three events that includes the measured recoil energies gives a 0.19% probability for the known-background-only hypothesis when tested against the alternative WIMP+background hypothesis. The highest likelihood occurs for a WIMP mass of 8.6 GeV/c2 and WIMP-nucleon cross section of 1.9×10(-41) cm2.

Abstract
Accurate estimation of the glomerular filtration rate (GFR) is essential for the evaluation of patient with chronic kidney disease (CKD). The present study was a comparison between modified gates GFR with laboratory measured CCR & MDRD formula based estimated GFR method. Pre-diagnosed 180 diabetic nephropathy patients were selected. All the time of evaluation the blood glucose of the patients were controlled and serum creatinine was stable. Then CCR was done and GFR was estimated by Modified Gates method & MDRD method. All the patients were categorized in 5 stages of CKD. They were matched for age, BMI, blood pressure, duration of diabetes, the blood sugar and HbA1C levels. The Gates GFR in stage-2 (70±13) & stage-3 (48±12) was closer with MDRD in stage-2 (77±8) and stage 3 (43±7). The CCR is closer in stage-1 (110±52) & stage-4 (30±10) with MDRD in stage-1 (112±13) and stage-4 (21±4). Association study showed MDRD GFR had highest correlation with Gates GFR (r=0.86; p<0.05). The estimation of glomerular filtration rate (GFR) in different methods varied significantly between each other at different stages of chronic kidney disease (CKD) in type 2 diabetic nephropathy subjects.

Abstract
We report on parity-violating asymmetries in the nucleon resonance region measured using inclusive inelastic scattering of 5-6 GeV longitudinally polarized electrons off an unpolarized deuterium target. These results are the first parity-violating asymmetry data in the resonance region beyond the Δ(1232). They provide a verification of quark-hadron duality-the equivalence of the quark- and hadron-based pictures of the nucleon-at the (10-15)% level in this electroweak observable, which is dominated by contributions from the nucleon electroweak γZ interference structure functions. In addition, the results provide constraints on nucleon resonance models relevant for calculating background corrections to elastic parity-violating electron scattering measurements.

Abstract
SETTING Eight operational locations for the Revised National Tuberculosis Control Programme in six Indian states. OBJECTIVE To assess the 6-month efficacy of an intermittent thrice-weekly directly observed treatment (DOT) regimen for tuberculous peripheral adenopathy and the need for prolongation of treatment to 9 months for non-resolution of lymphadenopathy. DESIGN Patients aged >5 years with tuberculous lymphadenopathy were included in the study. Patients were evaluated for resolution at repeat visits following treatment. Those with poor resolution at 6 months were randomised to extended treatment up to 9 months or observation without additional treatment. RESULTS Resolution of lymphadenopathy was observed at the end of 6 months in 517/551 (93.8%) patients. There was a significant difference in response among patients with and those without the presence of systemic symptoms. There was no association between treatment response and number, size, site, consistency and matting of lymphadenopathy. No differences in response were seen in the remaining 34 patients with or without extended treatment. CONCLUSION The operational efficacy of 6-month thrice-weekly DOT for peripheral tubercular lymphadenopathy was satisfactory. There was no evidence of additional benefits of prolonging treatment to 9 months.

Abstract
The natural history of abdominal aortic aneurysms (AAAs) renders them clinically silent for much of their evolution. These aneurysms will inevitably expand with time and, although surveillance programmes exist, an acutely ruptured AAA is still a relatively common clinical scenario. The classical presentation is with rapid haemodynamic deterioration with accompanying severe abdominal or back pain. Less commonly, patients may present with a stable haemodynamic profile and vague symptomatology; they are usually found to have a chronic contained rupture with a defect in the vascular wall with co-existent pseudoaneurysm and retroperitoneal haematoma formation. We report a rare case of AAA with posterior wall defect and erosion into the vertebral body with no accompanying pseudoaneurysm or haematoma and discuss the clinical implications of such a presentation.

Abstract
A 63-year old Yemeni male, known case of endstage renal disease (ESRD), hypertension and diabetes mellitus, underwent craniotomy and endoscopic removal of an intraventricular mass. Peri-operatively he was started on cefazolin, a normal diet and regular hemodialysis without heparin. The international normalising ratio (INR) increased rapidly, reaching 4.2 on day five but responded equally rapidly to parenteral Vitamin K and withdrawal of cefazolin. Cefazolin is an antibiotic commonly used in clinical practice because of its long half-life, narrow spectrum and its ability for dose adjustment in renal failure patients. We review the literature, discuss the risk factors of its use and suggest possible mechanisms causing the prolonged coagulation.

Abstract
Multiple system atrophy (MSA) is an unrelenting, sporadic, adult-onset, neurodegenerative disease of unknown aetiology. Its clinically progressive course is characterized by a variable combination of parkinsonism, cerebellar ataxia and/or autonomic dysfunction. Neuropathological examination often reveals gross abnormalities of the striatonigral and/or olivopontocerebellar systems, which upon microscopic examination are associated with severe neuronal loss, gliosis, myelin pallor and axonal degeneration. MSA is a member of a diverse group of neurodegenerative disorders termed α-synucleinopathies, due to the presence of abnormal α-synuclein positive cytoplasmic inclusions in oligodendrocytes, termed glial cytoplasmic inclusions. These are the hallmark neuropathological lesion of MSA and are thought to play a central role in the pathogenesis of the disease. In this review, neuropathological features of MSA are described in detail, along with recent advances in the pathophysiology and genetics of the disease. Our current knowledge of the expression and accumulation of α-synuclein, and efforts to model the disease in vitro and in vivo, are emphasized in this paper and have helped formulate a working hypothesis for the pathogenesis of MSA.

Abstract
We report the first measurement of the parity-violating asymmetry A(PV) in the elastic scattering of polarized electrons from 208Pb. A(PV) is sensitive to the radius of the neutron distribution (R(n)). The result A(PV)=0.656±0.060(stat)±0.014(syst) ppm corresponds to a difference between the radii of the neutron and proton distributions R(n)-R(p)=0.33(-0.18)(+0.16) fm and provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus.

Abstract
The parity-violating cross-section asymmetry in the elastic scattering of polarized electrons from unpolarized protons has been measured at a four-momentum transfer squared Q2 = 0.624 GeV2 and beam energy E(b) = 3.48 GeV to be A(PV) = -23.80 ± 0.78(stat) ± 0.36(syst) parts per million. This result is consistent with zero contribution of strange quarks to the combination of electric and magnetic form factors G(E)(s) + 0.517G(M)(s) = 0.003 ± 0.010(stat) ± 0.004(syst) ± 0.009(ff), where the third error is due to the limits of precision on the electromagnetic form factors and radiative corrections. With this measurement, the world data on strange contributions to nucleon form factors are seen to be consistent with zero and not more than a few percent of the proton form factors.

Abstract
During routine avian influenza surveillance in Pakistan, a low-pathogenic avian influenza virus (LPAI) subtype H3N1 was isolated for the first time from domestic chickens. The higher seroprevalence of H3N1 was recorded in both commercial and domestic poultry in ecological zones of Pakistan where the geographical proximity with neighboring countries and attractive birding sites provide better opportunities for frequent movements of wild and migratory birds, and their intermingling with the local domestic and commercial poultry. Subsequent whole genome sequencing of this virus revealed a new introduction of a reassortant Eurasian avian strain, which was distinguishable from corresponding human and swine strains isolated elsewhere. Phylogenetically, the HA gene was mostly clustered with Nordic (Scandinavian) strains of influenza viruses, whereas the NA and PB1 genes showed a maximum nucleotide sequence homology with the Indian H11N1, and the PB2 gene was found to be closely related to the Altai H5N2. The Matrix and NP genes of H3N1 mostly clustered with the European avian influenza viruses (AIV), whereas its NS and PA genes showed maximum nucleotide homologies with the African (Egypt) AIV strains. A sequence and amino acid analysis revealed an LP motif, avian-like receptor specificity, potential glycosylation sites, and sensitivities to oseltamivir, zanamivir, and amantadine. Some point mutations possessed by this Pakistani AIV H3N1 were also found in human, equine, and swine H3 influenza viruses. This H3N1 isolate showed less nucleotide sequence homology with the previously known Pakistani AIV as compared with other Eurasian AIV strains.

Abstract
Differentiating clinically between Parkinson's disease (PD) and the atypical parkinsonian syndromes of Progressive supranuclear palsy (PSP), corticobasal syndrome (CBS) and multiple system atrophy (MSA) is challenging but crucial for patient management and recruitment into clinical trials. Because PD (and the related disorder Dementia with Lewy bodies (DLB)) and MSA are characterised by the deposition of aggregated forms of α-synuclein protein (α-syn) in the brain, whereas CBS and PSP are tauopathies, we have developed immunoassays to detect levels of total and oligomeric forms of α-syn, and phosphorylated and phosphorylated oligomeric forms of α-syn, within body fluids, in an attempt to find a biomarker that will differentiate between these disorders. Levels of these 4 different forms of α-syn were measured in post mortem samples of ventricular cerebrospinal fluid (CSF) obtained from 76 patients with PD, DLB, PSP or MSA, and in 20 healthy controls. Mean CSF levels of total and oligomeric α-syn, and phosphorylated α-syn, did not vary significantly between the diagnostic groups, whereas mean CSF levels of phosphorylated oligomeric α-syn did differ significantly (p<0.001) amongst the different diagnostic groups. Although all 4 measures of α-syn were higher in patients with MSA compared to all other diagnostic groups, these were only significantly raised (p<0.001) in MSA compared to all other diagnostic groups, for phosphorylated oligomeric forms of α-syn. This suggests that this particular assay may have utility in differentiating MSA from control subject and patients with other α-synucleinopathies. However, it does not appear to be of help in distinguishing patients with PD and DLB from those with PSP or from control subjects. Western blots show that the principal form of α-syn within CSF is phosphorylated, and the finding that the phosphorylated oligomeric α-syn immunoassay appears to be the most informative of the 4 assays would be consistent with this observation.

Abstract
We present a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling α' to electrons. Such a particle A' can be produced in electron-nucleus fixed-target scattering and then decay to an e + e- pair, producing a narrow resonance in the QED trident spectrum. Using APEX test run data, we searched in the mass range 175-250 MeV, found no evidence for an A'→ e+ e- reaction, and set an upper limit of α'/α ~/= 10(-6). Our findings demonstrate that fixed-target searches can explore a new, wide, and important range of masses and couplings for sub-GeV forces.

Abstract
UNLABELLED This study was undertaken to improve the performance of a Chemotherapy Treatment Unit by increasing the throughput and reducing the average patient's waiting time. In order to achieve this objective, a scheduling template has been built. The scheduling template is a simple tool that can be used to schedule patients' arrival to the clinic. A simulation model of this system was built and several scenarios, that target match the arrival pattern of the patients and resources availability, were designed and evaluated. After performing detailed analysis, one scenario provide the best system's performance. A scheduling template has been developed based on this scenario. After implementing the new scheduling template, 22.5% more patients can be served. 1. INTRODUCTION CancerCare Manitoba is a provincially mandated cancer care agency. It is dedicated to provide quality care to those who have been diagnosed and are living with cancer. MacCharles Chemotherapy unit is specially built to provide chemotherapy treatment to the cancer patients of Winnipeg. In order to maintain an excellent service, it tries to ensure that patients get their treatment in a timely manner. It is challenging to maintain that goal because of the lack of a proper roster, the workload distribution and inefficient resource allotment. In order to maintain the satisfaction of the patients and the healthcare providers, by serving the maximum number of patients in a timely manner, it is necessary to develop an efficient scheduling template that matches the required demand with the availability of resources. This goal can be reached using simulation modelling. Simulation has proven to be an excellent modelling tool. It can be defined as building computer models that represent real world or hypothetical systems, and hence experimenting with these models to study system behaviour under different scenarios.1, 2 A study was undertaken at the Children's Hospital of Eastern Ontario to identify the issues behind the long waiting time of a emergency room.3 A 20---day field observation revealed that the availability of the staff physician and interaction affects the patient wait time. Jyväskylä et al.4 used simulation to test different process scenarios, allocate resources and perform activity---based cost analysis in the Emergency Department (ED) at the Central Hospital. The simulation also supported the study of a new operational method, named "triage-team" method without interrupting the main system. The proposed triage team method categorises the entire patient according to the urgency to see the doctor and allows the patient to complete the necessary test before being seen by the doctor for the first time. The simulation study showed that it will decrease the throughput time of the patient and reduce the utilisation of the specialist and enable the ordering all the tests the patient needs right after arrival, thus quickening the referral to treatment. Santibáñez et al.5 developed a discrete event simulation model of British Columbia Cancer Agency"s ambulatory care unit which was used to study the impact of scenarios considering different operational factors (delay in starting clinic), appointment schedule (appointment order, appointment adjustment, add---ons to the schedule) and resource allocation. It was found that the best outcomes were obtained when not one but multiple changes were implemented simultaneously. Sepúlveda et al.6 studied the M. D. Anderson Cancer Centre Orlando, which is a cancer treatment facility and built a simulation model to analyse and improve flow process and increase capacity in the main facility. Different scenarios were considered like, transferring laboratory and pharmacy areas, adding an extra blood draw room and applying different scheduling techniques of patients. The study shows that by increasing the number of short---term (four hours or less) patients in the morning could increase chair utilisation. Discrete event simulation also helps improve a service where staff are ignorant about the behaviour of the system as a whole; which can also be described as a real professional system. Niranjon et al.7 used simulation successfully where they had to face such constraints and lack of accessible data. Carlos et al. 8 used Total quality management and simulation - animation to improve the quality of the emergency room. Simulation was used to cover the key point of the emergency room and animation was used to indicate the areas of opportunity required. This study revealed that a long waiting time, overload personnel and increasing withdrawal rate of patients are caused by the lack of capacity in the emergency room. Baesler et al.9 developed a methodology for a cancer treatment facility to find stochastically a global optimum point for the control variables. A simulation model generated the output using a goal programming framework for all the objectives involved in the analysis. Later a genetic algorithm was responsible for performing the search for an improved solution. The control variables that were considered in this research are number of treatment chairs, number of drawing blood nurses, laboratory personnel, and pharmacy personnel. Guo et al. 10 presented a simulation framework considering demand for appointment, patient flow logic, distribution of resources, scheduling rules followed by the scheduler. The objective of the study was to develop a scheduling rule which will ensure that 95% of all the appointment requests should be seen within one week after the request is made to increase the level of patient satisfaction and balance the schedule of each doctor to maintain a fine harmony between "busy clinic" and "quiet clinic". Huschka et al.11 studied a healthcare system which was about to change their facility layout. In this case a simulation model study helped them to design a new healthcare practice by evaluating the change in layout before implementation. Historical data like the arrival rate of the patients, number of patients visited each day, patient flow logic, was used to build the current system model. Later, different scenarios were designed which measured the changes in the current layout and performance. Wijewickrama et al.12 developed a simulation model to evaluate appointment schedule (AS) for second time consultations and patient appointment sequence (PSEQ) in a multi---facility system. Five different appointment rule (ARULE) were considered: i) Baily; ii) 3Baily; iii) Individual (Ind); iv) two patients at a time (2AtaTime); v) Variable Interval and (V---I) rule. PSEQ is based on type of patients: Appointment patients (APs) and new patients (NPs). The different PSEQ that were studied in this study were: i) first--- come first---serve; ii) appointment patient at the beginning of the clinic (APBEG); iii) new patient at the beginning of the clinic (NPBEG); iv) assigning appointed and new patients in an alternating manner (ALTER); v) assigning a new patient after every five---appointment patients. Also patient no show (0% and 5%) and patient punctuality (PUNCT) (on---time and 10 minutes early) were also considered. The study found that ALTER---Ind. and ALTER5---Ind. performed best on 0% NOSHOW, on---time PUNCT and 5% NOSHOW, on---time PUNCT situation to reduce WT and IT per patient. As NOSHOW created slack time for waiting patients, their WT tends to reduce while IT increases due to unexpected cancellation. Earliness increases congestion whichin turn increases waiting time. Ramis et al.13 conducted a study of a Medical Imaging Center (MIC) to build a simulation model which was used to improve the patient journey through an imaging centre by reducing the wait time and making better use of the resources. The simulation model also used a Graphic User Interface (GUI) to provide the parameters of the centre, such as arrival rates, distances, processing times, resources and schedule. The simulation was used to measure the waiting time of the patients in different case scenarios. The study found that assigning a common function to the resource personnel could improve the waiting time of the patients. The objective of this study is to develop an efficient scheduling template that maximises the number of served patients and minimises the average patient's waiting time at the given resources availability. To accomplish this objective, we will build a simulation model which mimics the working conditions of the clinic. Then we will suggest different scenarios of matching the arrival pattern of the patients with the availability of the resources. Full experiments will be performed to evaluate these scenarios. Hence, a simple and practical scheduling template will be built based on the indentified best scenario. The developed simulation model is described in section 2, which consists of a description of the treatment room, and a description of the types of patients and treatment durations. In section 3, different improvement scenarios are described and their analysis is presented in section 4. Section 5 illustrates a scheduling template based on one of the improvement scenarios. Finally, the conclusion and future direction of our work is exhibited in section 6. 2. SIMULATION MODEL A simulation model represents the actual system and assists in visualising and evaluating the performance of the system under different scenarios without interrupting the actual system. Building a proper simulation model of a system consists of the following steps. Observing the system to understand the flow of the entities, key players, availability of resources and overall generic framework.Collecting the data on the number and type of entities, time consumed by the entities at each step of their journey, and availability of resources.After building the simulation model it is necessary to confirm that the model is valid.

Abstract
Isolated pleural effusion is a very rare presentation of malignant melanoma. A 46 year-old male patient presented to us with complaints of shortness of breath during the previous month. A contrast enhanced computed tomography (CECT) imaging scan of his thorax showed right-sided pleural effusion with the absence of any mass lesion or mediastinal lymphadenopathy. Cytology of his pleural fluid showed pigmented cells suggestive of malignant melanoma. Staining of the pleural fluid cells with immunohistological markers for melanoma (HMB 45 and S 100) were positive. An examination of his skin did not reveal any pigmented lesion, nor was there a past history of malignant melanoma for this patient. The patient responded well to therapy for malignant melanoma and has remained asymptomatic for the last year. This patient was diagnosed with a rare case of primary malignant melanoma of the pleura presenting as isolated pleural effusion.
