This study aimed to compare the use of hedges and boosters in medical sciences and engineering research articles. To fulfil this objective, the researcher provided 30 medical and 30 engineering research articles to identify the hedging and boosting devices used in them. The research articles were analysed according to lexical devices classification, focusing on hedges and boosters. The AntConc concordance software was used to identify the instances of hedges and boosters in both disciplines. Frequency, percentage and the Chi-square test were run to analyse the data. The results indicated that the difference between the frequency of hedges and boosters in medical sciences and engineering research articles was significant and meaningful. Moreover, the outcomes indicated that the most frequent hedges were epistemic modality verbs, quantifiers and nouns and the most frequent boosters were nouns, lexical verbs, modal verbs and adjectives. These discoveries of this paper may have some implications for the teaching of academic writing, especially to EFL learners. Keywords: Boosters, engineering research articles, hedges, medical research articles

Abstract Objective: To assess the diagnostic ability of abbreviated protocols of MRI (AP-MRI) compared with unenhanced MRI (UE-MRI) in mammographically occult cancers in patients with dense breast tissue.Materials and Methods: The retrospective analysis consisted of 102 patients without positive findings on mammography who received preoperative MRI full diagnostic protocols (FDP) between January 2015 and December 2018. Two breast radiologists read the UE, AP, and FDP. The interpretation times were recorded. The comparisons of the sensitivity, specificity and area under the curve of each MRI protocol, and the sensitivity of these protocols in each subgroup of different size tumors used the Chi-square test. The paired sample t-test was used for evaluating the difference of reading time of the three protocols.Results: Among 102 women, there were 68 cancers and two benign lesions in 64 patients and 38 patients had benign or negative findings. Both readers found the sensitivity and specificity of AP and UE-MRI were similar (p>0.05), whereas compared with FDP, UE had lower sensitivity (Reader 1/Reader 2: p=0.023, 0.004). For different lesion size groups, one of the readers found that AP and FDP had higher sensitivities than UE-MRI for detecting the lesions ≤10 mm in diameter (p=0.041, p=0.023). Compared with FDP, the average reading time of UE-MRI and AP was remarkably reduced (p < 0.001).Conclusion: AP-MRI had more advantages than UE-MRI to detect mammographically occult cancers, especially for breast tumors ≤10 mm in diameter.

Introduction: COVID-19 pandemic has overwhelmed the healthcare system of Pakistan. There has been observation regarding changes in pattern of patient presentation to emergency department (ED) for all diseases particularly cardiovascular. The aim of the study is to investigate these changes in cardiology consultations and compare pre-COVID-19 and COVID-19 era. Hypothesis: There is a significant difference in cardiology consultations during COVID era as compared to non-COVID era. Method: We collected data retrospectively of consecutive patients who visited emergency department (ED) during March-April 2019 (non-COVID era) and March-April 2020 (COVID era). Comparison has been made to quantify the differences in clinical characteristics, locality, admission, type, number, and reason of Cardiology consults generated. Results: We calculated the difference of 1351 patients between COVID and non-COVID era in terms of cardiology consults generated from Emergency department, using Chi-square test. Out of which 880 (59%) are male with mean age of 61(SD=15). Analysis shows pronounced augmentation in number of comorbidities [Hypertension(6%), Chronic kidney disease (6%), Diabetes (5%)] but there was 36% drop in total cardiology consultations and 43% reduction rate in patient’s ED visit from other cities during COVID era. There was 60% decrease in acute coronary syndrome presentation in COVID era, but fortuitously drastic increase (30%) in type II myocardial injury has been noted. Conclusion: There is a remarkable decline observed in patients presenting with cardiac manifestations during COVID era. Lack in timely care could have a pernicious impact on outcomes, global health care organizations should issue directions to adopt telemedicine services in underprivileged areas to provide timely care to cardiac patients.

This study sought to examine the sort, frequency, and sources of writing wrongs committed by adult Iranian EFL students. To score the participants’ written essays and speaking interviews, the four criteria specified for the IELTS Speaking and Writing Band Scores (British Council, 2014) were taken into consideration. The study also tried to comparatively analyze the error categories made by men and women learners regarding the type and frequency of their linguistic errors. To gather the information, from the population of faculty members at Hormozgan University of Medical Sciences (HUMS) in Bandarabbas, Iran, 100 adults, both male and female, with their age ranging from 31 to 52, were selected using convenient sampling. Based on their previous IELTS band scores ranging from 4 to 6, the members are separated into three groups.The results of data analysis revealed that verb tense was the very common grammatical mistake done by members in all three groups. For the cohesion and coherence and lexical sub-categories, relative clauses and incorrect use of target lexical item were regarded as the most common categories of errors. Outcomes of Chi-Square analyses also showed substantial differences among errors committed by participants in different groups. Finally, the comparison between male and female participants’ errors revealed that male participants made both written and spoken errors more than females. According to the results, recommendations, and any suggestions that are of importance to teachers and policymakers as well as to EFL learners are presented in detail.

The present study investigated the differences in attitudes and motivation between more effective and less effective learners studying at the first year of graduate university program. Based on this aim, first, the researcher developed the three-part 35-item attitude-motivation questionnaire of the present study based on the AMTB developed by Gardner (1985). Second, he selected 441 students (224 male & 217 female) studying at the first year of their graduate program at universities in East Azarbayjan province (Iran) as the participants of the study. Third, he administered the questionnaire of the study to the selected participants and asked them to complete it. Finally, he analyzed the data of the study in order to answer the mentioned research questions. The chi-square test was utilized to analyze the collected data of the study. The results of the study showed that there were significant differences between more effective and less effective learners’ attitudes and motivation. Based on the results of the study, it was argued that, the EFL syllabus designers and teachers should help the learners to become aware of their attitudes, and motivational orientations. Furthermore, they should make an effort to tailor classroom materials and classroom teaching to the EFL learners’ individual differences.

Background: Umbilical cord stump is a budding point for bacterial colonization subsequently leading to sepsis that contributes to high neonatal morbidity and mortality, if not properly managed. Antiseptic care can significantly reduce omphalitis and ultimately improve newborn survival. Objective of this study was to see the efficacy of 4% chlorhexidine use to prevent umbilical cord infection in neonates.Subjects and methods: It was a comparative analytical study conducted in Neonatal unit, Sir Ganga Ram Hospital (SGRH) Lahore from July, 2016 till January, 2017. One hundred neonates were enrolled and randomized into two equal group by simple random method (50 each). In one group, nothing was applied to cord while in chlorhexidine group, 4% chlorhexidine gel was applied on umbilicus and around it, once daily for 7 days or till cord detached whichever came early. First application was done by a nurse followed by duly trained mother/caregiver. The signs of omphalitis (redness, pus or localized oedema) were observed and recorded for each neonate in both groups. Chi square test was used to see the difference in omphalitis in these groups with p˂ 0.05 considered as statistically significant result.Results: Out of 100 neonates, 29 (58%) and 23 (46%) males while 21 (42%) and 27 (54%) females neonates belonged to dry care and chlorhexidine group respectively. Nineteen (38%) neonates with dry cord had omphalitis compared to only 5 (10%) in chlorhexidine group (p 0.001). Neonates with chlorhexidine application showed prolonged mean cord separation time (7.9±1.5 days) compared to dry care (6.1±1.8 days). Conclusion: The use of 4% Chlorhexidine was effective to lower omphalitis compared to neonates with dry cord care.

Intraepithelial Lesions

Background: ThinPrep® (TP) cervical cytology, as a liquid-based method, has many benefits but also a relatively high unsatisfactory rate due to debris/lubricant contamination and the presence of blood. These contaminants clog the TP filter and prevent the deposition of adequate diagnostic cells on the slide. An acetic acid wash (AAW) protocol is often used to lyse red blood cells, before preparing the TP slides. Design: From 23,291 TP cervical cytology specimens over a 4-month period, 2739 underwent AAW protocol due to initial unsatisfactory smear (UNS) with scant cellularity due to blood or being grossly bloody. Randomly selected 2739 cervical cytology specimens which did not undergo AAW from the same time period formed the control (non-AAW) group. Cytopathologic interpretations of AAW and non-AAW groups were compared using the Chi-square test. Results: About 94.2% of the 2739 cases which underwent AAW were subsequently satisfactory for evaluation with interpretations of atypical squamous cells of undetermined significance (ASCUS) 4.9% (135), low-grade squamous intraepithelial lesions (LSIL) 3.7% (102), and high-grade squamous intraepithelial lesions (HSIL) 1% (28). From the 2739 control cases, 96.3% were satisfactory with ASCUS 5.5% (151), LSIL 5.1% (139), and HSIL 0.7% (19). The prevalence of ASCUS interpretations was similar (P = 0.33). Although there were 32% more HSIL interpretations in the AAW group (28 in AAW vs. 19 in non-AAW), the difference was statistically insignificant (P = 0.18). AAW category; however, had significantly fewer LSIL interpretations (P = 0.02). The percentage of UNS cases remained higher in the AAW group with statistical significance (P < 0.01). Conclusions: While AAW had a significantly higher percent of UNS interpretations, the protocol was effective in rescuing 94.2% of specimens which otherwise may have been reported unsatisfactory. This improved patient care by avoiding a repeat test. The prevalence of ASCUS and HSIL interpretations between AAW and non-AAW groups were comparable. Though not statistically significant, HSIL interpretations were relatively higher in the AAW group. LSIL interpretations showed lower prevalence in AAW group.

Job satisfaction is a general attitude towards one’s job, the difference between the amount of reward workers receive and the amount they believe they should receive. Employee is a back bone of every organization, without employee no work can be done. So employee’s satisfaction is very important.Employees will be more satisfied if they get what they expected, job satisfaction relates to inner feelings of workers. As Udumalpet and Palani Taluk are famous for paper industries, the main aim of this study is to analyze the satisfaction level of paper mill employees. Chi-Square test and percentage analysis have been used in this study to analyze the job satisfaction of paper mill employees in Udumalpet and Palani Taluk. The study shows that only 44% of the employees are satisfied with the working conditions, 31% of them with the welfare facilities, 44% of them with the accident compensation, and 42% of them are satisfied with the rewards provided and 52% of them are satisfied with the grievance handling procedure. The organization may give importance to certain factors such as Canteen, rest room facilities, rewards, recognition and promotion policy so that satisfaction of the employees may be improved further.

: An emergency can be encountered anytime and anywhere. Minimal knowledge about medical emergency and their etiology, primary protocol for management must be known to avoid potential consequences. Hence, the present study was undertaken to compare the knowledge, and ability to handle the medical emergencies among the dental students. A cross-sectional survey was conducted among 100 randomly selected dental students (post-graduate students and interns) comprising of two groups of students those who had underwent training and those who did not. The data obtained was analyzed using the SPSS for windows version 22.0 released 2013. Independent chi square test was used for comparison of responses and independent student t-test was used for the comparison of mean scores. The significance level was set at p&#60;0.001. : The average mean knowledge and ability score was 68% & 61.4% respectively among the participants. On further comparison of mean knowledge & ability scores between the participants with & without basic life support training, participants with BLS training showed better knowledge than those without training and the difference was statistically significant between the two groups (p&#60;0.001%). The study found deficiencies in the knowledge and ability of untrained graduates to deal with medical emergencies as compared to trained.

Geographic information system-based multi-criteria decision analysis (GIS-MCDA) is a process of decision making where geographical data and value judgments are integrated. Analytic hierarchy process (AHP) is a useful technique in MCDA for determining weights. This study focuses on the evaluation of GIS-MCDA using different uncertainty levels in AHP. Best suitable sites for tiger habitats are located and analyzed in Sariska Wildlife Reserve, India using crisp and fuzzy AHP in GIS-MCDA, and thereafter, an optimal habitat suitability model is proposed. The percentage deviation over the uncertainty levels ranges slightly over 5%. The relative difference between CAHP and FAHP is nearly 2.7%. Chi-square test reveals relationship between the degree of uncertainty and the difference between the maps. For real-world situations with increased variability, fuzzification is preferred and shows the best results. The worldwide declining status of the tigers is a serious threat to the overall biodiversity, and the methods adopted in this study thus target their conservation and management.
