ap-Perspectives on endoscopic surveillance of dysplasia in inflammatory bowel disease: a survey of academic gastroenterologists

Background and study aims Dye-based chromoendos-copy (DBC) is the preferred method for endoscopic dysplasia surveillance in patients with inflammatory bowel disease (IBD). We sought to examine the uptake of, and perception toward DBC among academic gastroenterologists. Methods We conducted an online survey of academic members of the Canadian Association of Gastroenterology to assess their current dysplasia surveillance practice, uptake of DBC, and perceived barriers to adoption of DBC. Results Of the 150 physicians contacted, 49 (32.7%) responded to the survey. The majority of respondents report-ed subspecialty training in IBD (71.4%), and the median number of years in practice was 12. White-light endoscopy with random colonic biopsies was the preferred dysplasia screening method (73.5%). Only 26.5% of respondents routinely used DBC, despite institutional availability of over 60%. The major barriers to adoption of DBC were concerns about procedure duration (46.9%), concerns about cost (44.9%), and inadequate training (40.8%). Conclusion There is low uptake of DBC for dysplasia surveillance in IBD patients among academic gastroenterologists practicing in Canada. Additional studies should be completed to determine how to improve the uptake of DBC.
Constraints on families of smooth 4 –manifolds from Pin (cid:0) . 2 / –monopole

Using the Seiberg–Witten monopole equations, Baraglia recently proved that the inclusion Diff . X / , ! Homeo . X / is not a weak homotopy equivalence for most of simply connected closed smooth 4 –manifolds X . We generalize Baraglia’s result by using the Pin (cid:0) . 2 / –monopole equations instead. We also give new examples of 4 –manifolds X for which (cid:25) 0 . Diff . X // ! (cid:25) 0 . Homeo . X // are not surjections. 57R57; 57S05
COMPARISON OF INCIDENCE OF HEMI DIAPHRAGMATIC PARALYSIS USING M MODE ULTRASOUND FOLLOWING SUPRACLAVICULAR VERSUS INFRACLAVICULAR APPROACH TO BRACHIAL PLEXUS BLOCKS : A RANDOMIZED CONTROLLED TRIAL

Background: The occurrence of hemi-diaphragmatic paralysis with supraclavicular block is one of the recognized complication even when performed under ultrasound guidance. Our study tested the hypothesis that the infraclavicular approach results in a lower incidence of hemi diaphragmatic paralysis compared with supraclavicular blockade when a standard local anesthetic volume and concentration are used. Materials and Methods: With institutional human ethics board approval, we enrolled 80 patients undergoing upper extremity surgery below mid humerus in a randomized, blinded, parallel-group trial. Patients were assigned to ultrasound-guided supraclavicular (group S) or infraclavicular blockade (group I) with 20 mL of 0.5% local anesthetic. The primary objective the occurrence of complete hemi diaphragmatic paralysis at 30 minutes, defined as a greater than 75% reduction in diaphragmatic excursion measured with the voluntary sniff test and deep breathing test using M-mode diaphragm ultrasonography. Result: 17.5% in group S and 7.5% in group I had significant and complete diaphragmatic paralysis. During VS test there was no notable HDP at post block and after 15 minutes in both group. But the p value for the 30th min is significant with a value 0.0083 showing lesser incidence in the group I. Similarly, there no remarkable change in deep breathing test in both groups following post block and at the end of 15 minutes. Whereas, 11 patients were involved in group S versus 2 in group I making a significant p value 0.0019. Conclusion: Infraclavicular block technique exhibits a superior safety margin in comparison to supraclavicular approach as evidenced by low incidence of hemi diaphragmatic paralysis assessed through M mode ultrasound.
The relationship between strategic human resource management practices and employee performance: The moderating role of information communication technology (ICT) usage.

: The level of digitalization in Nigeria is tremendous and it has boosted and positively affected different areas of human life. The application and implementation of human resource management practices has been enhanced by the rapid trend in digitalization and technology. This study examined the relationship between strategic human resources management (SHRM) practices and employee performance: the moderating role of information and communication technology (ICT) usage of staff working at Warri Refinery and Petrochemical Company (WRPC), {a subsidiary of NNPC} Delta state, Nigeria. Consequently, a total number of 118 questionnaires were sent to the participant of the study of which 100 were fully completed by the respondents. The study adopted Pearson correlation and multiple regression analysis. The findings of the correlation analysis revealed that recruitment and selection, compensation and performance appraisal had positive correlation with employee performance while performance appraisal had no relationship with employee performance. Regression analysis showed that recruitment and selection had an influence on employee performance while compensation, training and development and performance appraisal had no influence on employee performance. It was also revealed that ICT usage moderated the relationship between SHRM practices and employee performance. On the basis of the findings, it was recommended that the organization under study should improve on these SHRM practices so as to enhance effectiveness in influencing employee performance. The use of ICT enhance efficiency in carrying out human resource management practice, therefore, the organization under study should improve on the use of ICT for faster and effectiveness of operation.
Short Term Effect of Biochar with Reduced Irrigation on Post-Harvest Soil Properties in W heat ( Triticum aestivum L.) Field

: Wheat ( Triticum aestivum L.) is one of the major cereal crop and excellent source of vegetable protein in human diet worldwide. Continuous crop cultivation without adding sufficient inputs to soil seriously influencing soil health and productivity. Improving soil fertility in drought regions to ensure food security through increase crop production is a great concern in Bangladesh. To evaluate the effect of biochar on soil properties at harvest in wheat field at reduced irrigated condition, we conducted a research at Sher-e-Bangla Agricultural University, Bangladesh in winter season during 2017 to 2018. The experiment was laid out in two factors split plot design with three replications. There were five levels of biochar application (B = 0 t ha , 1
Metamorphic and basin fluids in quartz–carbonate–sulphide veins in the SW Scottish Highlands: a stable isotope and fluid inclusion study

Metalliferous (Fe-Cu-Pb-Zn) quartz-carbonate-sulphide veins cut greenschist to epidote-amphibolite facies metamorphic rocks of the Dalradian, SW Scottish Highlands, with NE-SW to NW-SE trends, approximately parallel or perpendicular to regional structures. Early quartz was followed by pyrite, chalcopyrite, sphalerite, galena, barite, late dolomite-ankerite and clays. Both quartz-sulphide and carbonate vein mineralisation is associated with brecciation, indicating rapid release of fluid overpressure and hydraulic fracturing. Two distinct mineralising fluids were identified from fluid inclusion and stable isotope studies. High temperature (>350°C) quartz-precipitating fluids were moderately saline (4.0-12.7 wt.% NaCl equivalent) with low (approximately 0.05). Quartz 18O (+11.7 to +16.5) and sulphide 34S (13.6 to 1.1) indicate isotopic equilibrium with host metasediments (rock buffering) and a local metasedimentary source of sulphur. Later, low-temperature (TH = 120-200°C) fluids, probably associated with secondary carbonate, barite and clay formation, were also moderately saline (3.8-9.1 wt.% NaCl equivalent), but were strongly enriched in 18O relative to host Dalradian lithologies, as indicated by secondary dolomite-ankerite (18O = +17.0 to +29.0, 13C = 1.0 to 3.0). Compositions of carbonate-forming fluids were externally buffered. The veins record the fluid-rock interaction history of metamorphic host rocks during cooling, uplift and later extension. Early vein quartz precipitated under retrograde greenschist facies conditions from fluids probably derived by syn-metamorphic dehydration of deeper, higher-grade rocks during uplift and cooling of the Caledonian metamorphic complex. Veins are similar to those of mesothermal veins in younger Phanerozoic metamorphic belts, but are rare in the Scottish Dalradian. Early quartz veins were reactivated by deep penetration of low-temperature basin fluids that precipitated carbonate and clays in veins and adjacent Dalradian metasediments throughout the SW Highlands, probably in the Permo-Carboniferous. This event is consistent with paragenetically ambiguous barite with 34S characteristic of late Palaeozoic basinal brines.
(2014). Equal access, (Un)equal uptake: a longitudinal study of cataract surgery uptake in older people in England. BMC Health Services Research, 14,

Background: Uptake of cataract removal is a function of the effectiveness of the healthcare delivery services: services that are inaccessible, inappropriate, or unaffordable will not be utilised by (sub)populations, who consequently live with untreated cataracts. The aim of the study was to identify the relationship between individual wealth inequalities and uptake of cataract surgery in England, having controlled for the effects of potentially confounding variables. Methods: The final sample comprised of 2091 respondents from the English Longitudinal Study on Ageing (ELSA) who were diagnosed with cataracts prior to or during the study, aged 50 and over at wave 1, who had not undergone cataract surgery prior to the first survey observation, and had also provided a response in the second wave of the study. The uptake of cataract surgery was measured using the question, have you ever had cataract surgery? Data from waves 1-5 were used to identify those having received treatment during the 8-year observation window of ELSA. Survival analysis techniques were used. Results: Having controlled for the effects of potentially confounding variables, wealth did not make a statistically significant contribution to the overall fit of the Cox proportional hazard model nor were individual parameters statistically significant. Thus, respondents ’ socioeconomic position was not found to be a significant predictor in the uptake of cataract surgery in the UK. Receiving a recommendation from a medical professional was a key driving factors in the uptake of cataract surgery. Conclusions: Study findings suggest that uptake of cataract surgery among over 50s with a cataracts diagnosis in England do not discriminate on the grounds of individuals ’ material social position (wealth).
Bread Wheat Yield Response to Applications of Lime and Phosphorus in Welmera District, Central Highlands of Ethiopia

: Soil acidity and phosphorus deficiency is a major constraint to increase crop yields in tropical and subtropical regions. Phosphorus must be added to the soil plant system as mineral fertilizer to replenish what is removed by harvested crop parts. Efforts to ameliorate the deleterious effects of soil acidity must accompanied by appropriate rate of lime and P fertilizer. Therefore, this investigation was undertaken to study yield response of bread wheat to lime and P fertilizer for better yield. The experiment was conducted in 2018 at Holeta Agricultural Research Center (HARC), Robgebeya (RG) and Watabacha Minjaro (WM) sites in Welmera District of Oromia Regional National State. Acidic fields that were not reclaimed with lime for the last five years were selected and sampled. The experimental treatments comprised six rates of lime (0, 1.56, 2.34, 3.12, 3.9 and 4.68 t ha ) and three rates of P (0, 16.5 and 33 kg ha ) arranged in factorial randomized complete block design 1
COMPARISON OF FULL OUTLINE OF UNRESPONSIVENESS SCORE (FOUR) WITH GLASGOW COMA SCALE (GCS) IN CHILDREN ADMITTED IN PICU WITH IMPAIRED NEUROLOGICAL STATUS

Background: Assessment of consciousness level is a basic ability that medical personnel, especially doctors and nurses should master. There are various types of scales to measure consciousness level of patient. One of the most famous and most widely applied scale is Glasgow Coma Scale (GCS). The GCS presents several weaknesses, such as limited utility in intubated patients as well as an inability to estimate brainstem reflexes. The objective is to determine predictive accuracy of FOUR score against GCS. To assess the neurological outcome based on modified Rankin scale. Materials and Methods: Children, who are admitted in the PICU with altered level of consciousness, recruited in this study based on inclusion and exclusion criteria after obtaining written informed consent from the parents or caregivers. Detailed clinical and neurological examination done in all study subjects. Full Outline of Un Responsiveness Score (FOUR score) and Glasgow Coma Scale (GCS) collected for each patient separately and simultaneously after admissions in the intensive care unit. Result: The area under ROC showed FOUR score and GCS were good at discriminating survivors and no survivors (P < 0.05 and P < 0.05, respectively). The Area Under Curve (AUC) = 0.968 for FOUR score and the AUC = 1 for GCS, pointed out that the discrimination power of GCS score was better than FOUR. Among admitted children 7.8% children had no evident disability despite symptoms and 1.3% of children had slight disability, with an inability to carry out all previous activities at the time of discharge. Conclusion: FOUR score provides no significant advantage over GCS in predicting morbidity and mortality in children in PICU with impaired neurological status.
Online Search and Product Rankings: A Double Logit Approach ∗

We develop a flexible yet tractable model of consumer search and choice, and apply it to the problem of product rankings optimization by online retail platforms. In the model, products are characterized by a search index, which governs what consumers search; and a utility index, which governs which of the searched options is purchased. We show that this framework generalizes several commonly used search models. We then consider how platforms should assign products to search ranks. To optimize consumer surplus, platforms should facilitate product discovery by promoting “diamonds in the rough,” products whose utility index exceeds their search index. By contrast, to maximize static revenues, the platform should favor high-margin products, creating a tension between the two objectives. We develop computationally tractable algorithms for estimating consumer preferences and optimizing rankings, and we provide approximate optimality guarantees in the latter case. When we apply our approach to data from Expedia, our suggested ranking achieves both higher consumer surplus and higher revenues than is achieved by the Expedia ranking, and also dominates ranking the products in order of utility.
International Review of Research in Open and Distributed Learning University Students’ Persistence With Technology-Mediated Distance Education: A Response to COVID-19 and Beyond in Zimbabwe

Technology-mediated distance education (TDE) has become part of the new normal in the range of teaching strategies used in universities in Zimbabwe. Contemporary literature abounds with studies that highlight challenges associated with access to education in universities, yet very little is highlighted about how TDE can be used to enhance access to education in Zimbabwean universities during the COVID-19 era and beyond. The purpose of this study was therefore to investigate determinants of students’ behavioural intentions to persist with TDE in universities in Zimbabwe during COVID-19 and beyond. The study employed a quantitative approach that used a self-constructed structured questionnaire for data collection from a sample of 1,300 distance learning students selected from five universities using a stratified random sampling strategy. Structural equation modelling using IBM SPSS Amos 22 was used for data analysis. Results of the study show that cultural and norms issues (β = .325; p < .001) and characteristics of the students (β = .329; p < .001), the lecturer (β = .362; p < .001), the institution (β = .427; p < .001), and external stakeholders (β = .279; p < .001) were all significantly associated with the behavioural intentions of university students to persist with TDE. Results of this study have implications for both policy and practice with regard to implementing TDE in universities.
PREDICTING SARCASM AND POLARITY IN ARABIC TEXT AUTOMATICALLY: SUPERVISED MACHINE LEARNING APPROACH

Arabic text is one of the main challenges for machine learning and sentiment analysis to this day. In this paper, we introduce an Arabic text classifier that predicts both polarity and sarcasm. Six different supervised machine learning classification algorithms were used and gauged on our Arabic classifiers: Logistic Regression (LR), Multinomial Naïve Bayes (NB), Decision Tree (DT), Support Vector Machine (SVM), Random Forest (RF) and K-Nearest Neighbor (KNN) along with different N-gram for tokenizing and TF-IDF for feature selection. SVM shows the best accuracy results (F1-score of 58.5%) when predicting polarity, while DT achieves the best accuracy results (F1-score of 64.4%) when predicting sarcasm. Previous sarcasm classification research achieved (F1-score of 46%) accuracy using BiLSTM on Arabic corpus.
DETERMINING THE CLINICAL AND EPIDEMIOLOGICAL PROFILE OF THE VARIOUS IDIOPATHIC PHOTO-DERMATOSES IN A PARTICULAR POPULATION

Background: Solar radiation is the main source of light to the world. The spectrum of solar radiation is broad, but only 2–3% of ultraviolet light (UV), approximately 32% of visible light, slightly < 66% of infrared light reach the Earth’s surface. Photodermatoses represent a heterogenous group of skin disorders, caused or aggravated by UV radiation and ⁄or visible light. Those distinct photosesnsitive cutaneous conditions can be classified into four main categories. Idiopathic photodermatoses refers to those photosensitive disorders which are probably auto-immunity mediated. These include polymorphous light eruption (PMLE), chronic actinic dermatitis, solar urticaria, actinic prurigo (AP) and hydroa vacciniforme (HV). Materials and Methods: This study was undertaken in the Department of Skin and VD, S.C. B Medical College, Cuttack, Odisha within a Period of one year from August 2013 to July 2014. All the patients attending the Skin & vp OPD, referred from other departments and cases admitted in the wards of Skin & VD department who were diagnosed with a particular idiopathic photo dermatoses. All the age groups and both sexes were included. Subjects taking systemic steroids or any photosensitizing drug were not included. The diagnosis was based on history and clinical assessment mainly, and investigations (histology, blood & urine examination) in selected cases were done to rule out other diseases (LE and Porphyrias). Result: The incidence of individual photo dermatoses per 100 patients ranged between 0.54 for commonly occurring disorder (PMLE) to 0.0% for the rarest disorder (HV). In our study, a total of 170 cases of idiopathic photo dermatoses were recorded over a period of one year, with their frequency being 0.61% (170 out of 28066 of all skin OPD cases). Maximum number of cases of PMLE 33.3% (51 out of 151 cases) belonged to the age group 21-30 years. Females outnumbered the males in all age group except in 41-50 years and >60 years, where equal sex incidence were seen. In CAD, most common affected age group was 51-6 years at 66.7% and males outnumbered females in all age groups. In AP, maximum number of cases (75%) belonged to the age group11-20 years and equal sex incidence was seen. Conclusion: As this was a hospital based study, results may not reflect status of disease in a community and also being a tertiary care centre, most of the cases belong to geographic area away from the local population. So this study may not reflect general population, but it depicts the general trend of the diasease. Hence, a study on a larger scale should be encouraged to further substantiate the above results.
PREVALENCE OF CO-MORBIDITIES AND ITS CORRELATION WITH SEVERITY OF COVID-19 DISEASE: A RETROSPECTIVE SINGLE CENTRE STUDY

Background: The COVID-19 pandemic has posed significant challenges to global healthcare systems. Understanding the prevalence of co-morbidities and their association with disease severity is crucial for effective patient management and resource allocation. The aim and objective are to investigate the prevalence of co-morbidities in COVID-19 patients and explore their correlation with disease severity. Materials and Methods: This prospective single-center study enrolled 88 confirmed COVID19 patients admitted to the hospital. Relevant clinical data, including age, sex, pre-existing co-morbidities, and COVID-19 disease severity, were collected. Result: Among the 88 patients, the most common co-morbidities observed were hypertension (n=34, 38.6%), diabetes mellitus (n=28, 31.8%), and obesity (n=19, 21.6%). Other co-morbidities included cardiovascular disease (n=11, 12.5%), chronic respiratory conditions (n=9, 10.2%), and immunosuppressive disorders (n=7, 7.9%). Patients with multiple co-morbidities accounted for 22.7% (n=20) of the cohort. Regarding disease severity, 60 patients (68.2%) presented with mild symptoms, 22 patients (25.0%) had moderate disease, and 6 patients (6.8%) were classified as severe cases. Notably, all patients classified as severe had at least one underlying co-morbidity. Hypertension and diabetes mellitus were the most frequently observed co-morbidities among severe cases, with 83.3% (n=5) of severe patients having hypertension and 66.7% (n=4) having diabetes mellitus. Conclusion: This retrospective single-center study provides insights into the prevalence of comorbidities among COVID-19 patients and their correlation with disease severity. Hypertension and diabetes mellitus were the most common co-morbidities observed in severe cases. Identifying such risk factors for severe COVID-19 can aid healthcare professionals in early risk stratification and prompt management of high-risk patients, potentially reducing morbidity and mortality rates. Further large-scale studies are warranted to validate these findings and to explore other potential risk factors associated with severe COVID-19 outcomes
