    Abstract:                                                     Obstructive jaundice is not uncommon in this area certainly with what is reported in the literature, malignant jaundice is more common than choledocholithiasis. The pre-operative management followed the international guidelines; most of the surgery done to the malignant jaundice was palliative because of the late presentation. Endoscopic service in management of obstructive jaundice is important and shall be utelized after completion of the new GIT Centre-Wad Medani Hospital. This study was a prospective cross sectional descriptive study, conducted in Wad Medani hospital - Gezira state – Sudan from March 2014 to March 2015. Wad Medani Teaching Hospital is a tertiary hospital with 600 beds serving all Gezira state and nearby states  Material and Method: 124 patients admitted to hospital with symptoms and signs of obstructive jaundice including; yellow coloration of the sclera, dark urine,pale stools, itching, with or without the association of vomiting, abdominal pain, abdominal mass and weight loss. Diagnosis was confirmed by history, examination and biochemical and radiological investigations.The data was analyzed by computer using SSPS. Results: 52(41.9%) were males and72 (51.8%) were females, with male to female ratio of 1:1.3. The cases of obstructive jaundice were found to be distributed among their age groups from 18-40yr (15.3%),41-60yr(31.5%) , 60yr and above (53.2%). Definitive diagnosis after completion of investigations results showed that cases due to common bile duct (CBD) stone and carcinoma of the head of pancrease were 55 (44.4%) and 52 (41.9%) respectively. The relation between the diagnosis and sex results showed CBD stone in females was 37(51.4%) where as in males  carcinoma of the head of pancrease was 25(48.11%), ERCP was used in 67(54%) patients both for diagnostic and therapeutic indications. The operative intervention was also studied for all patients with obstructive jaundice and the results showed that 48(38.7%) patients underwent surgical intervention with 7(5.6%) CBD exploration and 41(33.1%) by pass surgical operation. Conclusion: ERCP has a promising role in the study area in managing patients with obstructive jaundice. The family physicians   have an important role to play in early detection and referral of patients with obstructive jaundice to hospitals to avoid delayed presentation and minimize the harmful effects of hyper bilirubinemia on the   liver so the step should start with how to detect the case and after that what to do for the case before referral to nearby hospital

    Objective: Deterioration in ventricular function is often observed in patients treated with anthracyclines for cancer. There is a paucity of evidence on interventions that might provide cardio-protection. We investigated whether prophylactic use of carvedilol can prevent doxorubicin-induced cardiotoxicity and whether any observed effect is dose related. Methods: A prospective, randomized, double-blind study in patients treated with doxorubicin, comparing placebo (n = 38) with different doses of carvedilol [6.25 mg/day (n = 41), 12.5 mg/day (n = 38) or 25 mg/day (n = 37)]. The primary endpoint was the measured change in left ventricular ejection fraction (LVEF) from baseline to 6 months. Results: LVEF decreased from 62 ± 5% at baseline to 58 ± 7% at 6-months (p = 0.002) in patients assigned to placebo but no statistically significant changes were observed in any of the 3 carvedilol groups. At 6 months, only one of 116 patients (1%) assigned to carvedilol had an LVEF < 50% compared to four of the 38 assigned to placebo (11%), (p = 0.013). No significant differences were noted between carvedilol and placebo in terms of the development of diastolic dysfunction, clinically overt heart failure or death. Conclusions: Carvedilol might prevent deterioration in LVEF in cancer patients treated with doxorubicin. This effect may not be dose related within the studied range

    The study aimed to examine the effects of augmented reality technology on the development of origami-style pattern designing skills among female students in the clothing and textile field, as well as to explore their attitudes towards this technology. The quasi-experimental approach was employed to achieve the research objectives, with a sample of 24 female students from the Fourth Grade of the Department of Clothing and Textile, Faculty of Home Economics at Al-Azhar University. The participants were divided into two groups: a control group of 12 students who studied in the traditional way, and an experimental group of 12 students who used augmented reality technology to learn. The study was conducted in the second semester of the academic year 2020/2021. The results showed that there was a statistically significant difference (at a significance level of 0.01) between the average scores of the control group and the experimental group in both cognitive achievement and skill performance, with the experimental group performing better. Additionally, the retention of learned information was higher among the experimental group, and they had a more positive attitude towards using augmented reality technology in learning

    New technique for using SMES to limit fault currents in wind farm power systems

    Get PDF
    This paper introduces a new scheme, which uses a multifunctional superconducting device that can be used as an energy storage and as a fault current limiter. It is denoted as a superconducting magnetic energy storage - fault current limiter (SMES-FCL) and is modeled as a number of pancakes. It is connected to a wind turbine power system via tertiary transformer and power converters. A complete control scheme is built to achieve effective power transfer between the superconducting coil and the power system during normal operation to smooth the wind turbine output power. The fault current limiting function is implemented using a new technique that inserts a few pancakes from the whole SMES coil into the main electrical system during the fault and isolates the remaining pancakes. The number of pancakes used to limit the fault is quenched and operates as a resistive fault current limiter. The whole system including the wind turbine, the SMES-FCL model, and the interface circuit are implemented using PSCAD/EMTDC computer package. Also, the control scheme of SMES-FCL is built based on a feedback current signal to enable its operation into the two modes

    Avian influenza H5N1 surveillance and its dynamics in poultry in live bird markets, Egypt

    H5N1, a highly pathogenic avian influenza (H5N1 HPAI), is an endemic disease that is significant for public health in Egypt. Live bird markets (LBMs) are widespread in Egypt and play an important role in HPAI disease dynamics. The aim of the study was to evaluate the H5N1 HPAI prevalence in representative LBMs from 2009 to 2014, assess the effects of other variables and evaluate past outbreaks and human cases. It was found that ducks and geese are high-risk species and that the prevalence of H5N1 HPAI was higher immediately after the political crises of 2011. The end of a calendar year (June to December) was a high-risk period for positive samples, and the risk in urban LBMs was twice the risk in rural LBMs. Winter and political unrest was associated with higher H5N1 HPAI prevalence. Both human and poultry populations will continue to rise in Egypt, so continued poultry outbreaks are likely to be linked to more human cases. LBMs will continue to play a role in the dynamics of poultry disease in Egypt, and there is a need to reorganize markets in terms of biosecurity and traceability. It may also be beneficial to reduce inter-governorate inter-regional movements associated with poultry trade through promotion of regional trade or in the alternative provide sanitary features along the poultry market chain to reduce the speed of H5N1 HPAI infections. Policy formulation, design and enforcement must be pro-poor, and consideration of the sociocultural and economic realities in Egypt is important. The LBMs provide ideal platforms to carry out sound surveillance plans and mitigate zoonotic risks of H5N1 HPAI to humans.Data S1.

    Longitudinal expression profiling identifies a poor risk subset of patients with ABC-type Diffuse Large B Cell Lymphoma.

    Despite the effectiveness of immuno-chemotherapy, 40% of patients with diffuse large B-cell lymphoma (DLBCL) experience relapse or refractory disease. Longitudinal studies have previously focused on the mutational landscape of relapse but falling short of providing a consistent relapse-specific genetic signature. In our study, we have focussed attention on the changes in gene expression profile accompanying DLBCL relapse using archival paired diagnostic/relapse specimens from 38 de novo DLBCL patients. Cell of origin remained stable from diagnosis to relapse in 84% of patients, with only a single patient showing COO switching from ABC to GCB. Analysis of the transcriptomic changes that occur following relapse suggest ABC and GCB relapses are mediated via different mechanisms. We developed a 30-gene discriminator for ABC-DLBCLs derived from relapse-associated genes, that defined clinically distinct high and low risk subgroups in ABC-DLBCLs at diagnosis in datasets comprising both population-based and clinical trial cohorts. This signature also identified a population of <60-year-old patients with superior PFS and OS treated with Ibrutinib-R-CHOP as part of the PHOENIX trial. Altogether this new signature adds to the existing toolkit of putative genetic predictors now available in DLBCL that can be readily assessed as part of prospective clinical trials

Longitudinal studies have previously focused on the mutational landscape of relapse but fell short of providing a consistent relapse-specific genetic signature.

    BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.
