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.

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.

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.

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.

Abstract Background The objective of the study described in this article was to examine whether, and to what extent, Australian public hospitals use knowledge terminology, i.e. a body of knowledge-related terms, on their websites. The paper also discusses the difference in the level of such communication between large and small hospitals, the factors affecting the use of the knowledge-related terms in the communication and the similarities/differences between the use of knowledge terms in Australian public hospitals and large/small companies in Australia. Methods 151 Australian public hospitals were included in the research sample: 51 large and 100 small hospitals. Using the method of content analysis, websites mentioning knowledge creation, knowledge sharing, knowledge implementation, and knowledge retention were identified, along with the number of these mentions. Descriptive statistics and chi square test of independence were used to provide answers to four research questions. Results Of the 151 hospitals included in the sample, 30 had no website and 62 (50 small and 12 large) had a single page website. The study found that there are differences between Australian public hospitals regarding the level of their knowledge communication on their websites, both between small and large hospitals and between the individual hospitals within the large and small hospital groups. Conclusions A well-known saying goes “For the mouth speaks what the heart is full of”. Effective communication of knowledge-related terminologies to both internal and external stakeholders, i.e. the parties who access the websites, is therefore an indication of a knowledge focus in the public hospitals. Large hospitals are generally more active in communicating knowledge terms, although there are some exceptions. Some of the small hospitals can lead by example, but most of them do not include knowledge terminology in their communication on websites.

ABSTRACT Objective: to compare the efficacy of three active heating methods in the prevention of intraoperative hypothermia in open gastroenterological surgeries. Method: randomized clinical trial with a sample of 75 patients, whose initial body temperature measured by a tympanic thermometer. Esophageal temperature <36ºC was considered hypothermic. Patients were divided into three groups using: thermal mattress, underbody forced-air warming blanket and heated infusion system. The tympanic and esophageal temperatures were measured at different times of the intraoperative period, but the temperature considered gold standard was the esophageal. To evaluate the homogeneity of the groups, we used chi-square test (categorical variables). In the comparison of temperature measurements over time, the analysis of variance (ANOVA) and the contrast profile test were used for the difference in temperature between the times. The non-parametric Kruskal-Wallis test was used to compare the three groups. The level of significance was 5%. Results: regarding the studied variables, the groups were not homogeneous as to the categorical variable sex. All patients presented hypothermia during the intraoperative period (p> 0.05). Conclusion: there was no significant difference between the heating methods in the prevention of intraoperative hypothermia. REBEC - Brazilian Registry of Clinical Trials (RBR- no. 52shjp).

Abstract Clinical-pathological sessions are a good method for solving diagnostic and/or therapeutic problems in patients with hemopathies. In these sessions, errors made during health care given to the patient can be detected. By analyzing how and why these errors are made, we can improve patient care and prevent further mistakes. The objective of this study is to describe 34 errors identified in 874 patients with hemopathies at clinical-pathological meetings in two centers, performed with the aim of solving a diagnostic problem and/or a therapeutic decision or due to a great interest of the case, in two institutions, over 22 years (1982–2004). An intererdisciplinary team of hematology specialists gathered every week at interactive sessions of about 45 minutes each, in both institutions. The methodology of sessions was: a description of the medical history of a patient in a one or two-page report and a revision of the different samples (peripheral blood, bone marrow and lymph node morphology, immunocytochemistry, flow-cytometry, cytogenetic and molecular studies) with the aid of a microscope and a TV monitor. A diagnostic and/or treatment were proposed at the end of the session. Eight-hundred and seventy-four reports were analyzed. All the diagnostics were classified: chronic lymphoproliferatives disorders (445), myeloproliferative and myelodysplastic syndromes (136), acute leukemias (136), other haematological diseases (74), non-haematological diseases (31), without a diagnosis after the meeting (52). We identified diagnostic (D) and therapeutic (T) mistakes and considered as the main causes of the medical error (mistake in the diagnosis and/or treatment): lack of expertise (LE), malpractice (MP), impetuosity (IM), bad logistic support (LS), inexplicable (IN). We divided the 22 years into two decades and each error was classified in one of these two groups. Our own mistakes (OM) and the errors made in other institutions (OI) were identified. A comparison between number of errors made in the first 11 years and the second 11 years was made using a Chi-square test. P&lt;0.05 was considered statistically significant. Thirty-four errors (4 %) were detected, being more D and T (20) rather than only D (14). The type of error detected was: 17 LE, 7 MP, 5 IM, 3 LS, 2 IN. Twenty errors were OM and 14 were made in OI. The difference in the proportion of errors detected during the first and the second decade (6.6 % vs 2.8 %, respectively) was statistically significant (p=0.05). No error led to the death of any patient or were life-threatening in any way. Errors may be made in the diagnosis and treatment of hematologic patients. Although the rate of error found appears to be high, it can be considered as low, since the cases were presented in scientific sessions because of diagnostic and/or therapeutic problems. One of the best ways of improving how to care for future patients is to detect and analyze the errors made. Many lessons can be learnt in this way.
