Purpose: The purpose of this study is to highlight the reliability of clinical DWI mismatch (CDM) in the identification of patients with large infarct growth. Methods: We prospectively reviewed 21 ischemic stroke patients who underwent DWI imaging within 72 hours from stroke symptoms onset. Description of images was made by experienced radiologists. Lesion volumes were assessed by manually outlining the DWI infarct lesions area. The percentage of infarct growth was calculated by dividing the difference between second and first infarct volume by the first infarct volume times 100. The NIHSS scores were assessed by an experienced neurologist. CDM was defined as NIHSS score ≥8 and initial infarct volume on DWI ≤ 25 mL. Statistical Tests: We assessed the relationships of variables within different groups of CDM using nonparametric tests—Kruskal-Wallis and chi-square test. Sensitivity and specificity of CDM to predict large infarct growth were tested by using crosstabs table. Results: CDM was present in 36.8% of our patients and was associated with the percentage of infarct growth ( P < .01). The mean percentage growth was high in patients with CDM (211.8%) while it was low in the group of patients without CDM (5.7%; group B and 10.7%; group C). The sensitivity and specificity of CDM to predict infarct growth was 77.8% vs 100% with a likelihood ratio of 15.4 ( P = .0004). Conclusion: The approach of comparing CDM and percentage of infarct growth proved that the concept of CDM can accurately indicate the existence of a large volume of tissue at risk of infarction—penumbra.

Introduction: Resting tongue position is of crucial importance in the stability and retention of complete denture, particularly of the mandible. The retracted position of the tongue has been found to be higher in edentulous subjects when compared to dentate subjects and highest in completely edentulous individuals. Objectives: To evaluate the resting tongue position in completely edentulous as well as partially edentulous patients. Methods: 50 edentulous and 50 partially edentulous (mandible) subjects were taken. The edentulous group was divided into two groups according to the duration of edentulousness. Group A: Recently extracted edentulous subjects (< 1 year), Group B: Long term edentulous subjects (> 1 years). The partially edentulous group was divided into 4 groups according to Kennedy classification. The resting tongue positions of all the individuals were determined. The data was analyzed using SPSS statistical tests like mean, standard deviation, proportion, Chi-square test and Independent T-test. Results: In complete edentulous group, the abnormal upper was the most frequent (38%). In partial edentulous group, the normal lower was the most frequently observed tongue position with 34%. The abnormal tongue position was found in 68% and 40% in completely edentulous and partially edentulous subjects respectively. Conclusion: Retracted resting tongue position is found to be higher in completely edentulous subjects than partially edentulous ones.

Background: To manage and reduce painful procedures in the emergency wards, procedural sedation as well as analgesia can be used. Propofol combinations are the most common short-acting intravenous sedative drugs in the field of emergency medicine. Objectives: This research aimed to compare the effectiveness, safety, and complications of intravenous infusion of ketofol with fentofol in painful emergency procedures. Methods: This study was a randomized, double-blind clinical trial. Sampling was simple and used random assignment; 196 participants were randomly assigned to two groups of 98 patients each. In each group, injection was done with fentanyl–propofol or ketamine–propofol. For data gathering, pre-procedure, and procedure, modified Aldrete’s scoring checklist was used. In order to determine the levels of sedation, we used the Ramsay Sedation Scale. Data analysis was performed via SPSS Version 20 using statistical tests such as mean ± standard division, t-test, chi-square test, and analysis of variance. Results: Among the participants in this study, shoulder procedure was performed more than other procedures (56.6%). The mean of recovery time was significantly different in the two groups (ketofol: 5.65 ± 0.35 vs fentofol: 9.33 ± 0.78); the recovery time in group B (fentofol) was longer than that in group A (ketofol) (p = 0.001). Drug complications were statistically significant in the two groups, and complications by ketofol were less than those by fentofol (p = 0.001). “Hypotension and bradycardia” were observed with fentofol and “tachycardia” was observed with ketofol. The performance of these two drugs was not the same when subject to various procedures. Conclusion: Results of this study revealed that ketofol provided better analgesia and sedation, faster recovery time, lesser complications and adverse events, and reduced bradycardia and hypotension.

Implementation of IMD in hospitals has decreased from the previous year and has not reached the target set by the government. Some IMD implementation processes have not been carried out according to applicable standards. So that babies do not get an IMD in accordance with existing SOPs. The purpose of this study was to determine the determinant factors associated with the implementation of the IMD by midwives in the Midwifery and Maternity Room Emergency Room (IGD) at the Anutapura General Hospital in Palu. This research method is analytical with cross sectional approach. The population of this study was that all midwives in the obstetrics emergency room and maternity room at Anutapura Palu Hospital were 37 respondents. The sample in this study is total sampling. The analysis used was univariate, and bivariate analysis using the chi square test with a confidence level of 95% (α = 0.05). The results of statistical tests on variable knowledge of midwives with the implementation of IMD p value: 0.018 (p value <0.05). APN training with the implementation of IMD p value: 0.697 (p value> 0.05). length of work with the implementation of IMD p value: 0.029 (p value <0.05). and peer support with the implementation of IMD p value: 0.007 (p value <0.05). Conclusions there is a relationship between knowledge, length of work, peer support with the implementation of the IMD, and training factors that have nothing to do with IMD implementation. The strongest factor in the relationship is peer support. It is recommended that the Anutarapura Palu Hospital be able to motivate midwives so that they can further enhance their role in the implementation and provide support to their colleagues so that the implementation of the IMD can be carried out in accordance with applicable standards.Keywords: Knowledge, APN Training, Duration of work, Implementation of IMD

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.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p &lt; 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p&gt;0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

This article aims to confront four theories of firm growth – Optimum Firm Size, Stage Theory of Growth, The Theory of the Growth of the Firm and Dynamic Capabilities – with empirical data derived from a backward-looking longitudinal qualitative case of the growth trajectory of a Brazilian capital goods firm. To do so, we employed Degree of Freedom-Analysis for data analysis. This technique aims to test the empirical strengths of competing theories using statistical tests, in particular Chi-square test. Our results suggest that none of the four theories fully explained the growth of the firm we chose as empirical case. Nevertheless, Dynamic Capabilities was regarded as providing a more satisfactory explanatory power.

Abstract Objective: To analyze the occurrence of Maternal Mortality in general and in the indigenous population in the state of Pará. Method: A quantitative, analytical and retrospective study was performed, covering a historical series from 2005 to 2014. For the analysis of the results, non-parametric statistical tests, the Chi-square test and the G test were processed in the BioStat 5.0 software program. Results: A total of 884 maternal deaths were reported in the state of Pará, corresponding to a Mortality Rate of 60.7 per 100,000 live births for non-indigenous women and 135.8 per 100,000 live births for indigenous women. Oedema, proteinuria and hypertensive disorders in pregnancy, childbirth and puerperium corresponded to 30.5% (n = 270). Conclusion and Implications for the Practice: Maternal mortality remains a serious public health problem in the state of Pará, clearly demonstrating that indigenous pregnant women require greater care, since they showed higher Maternal Mortality Rates when compared to non-indigenous women.

The percentage of families in Lapulu Village that had healthy latrines was 64,84% who met the health requirements and 35,16% who did not meet the health requirements in 2019. This shows that the ownership of healthy latrines is still lower than the national achievement. This study aims to determine the factors associated with low ownership of healthy latrines in the coastal areas of Lapulu Village, Kendari City. The research design was observational, with a cross-sectional approach. The population in this study was 437 respondents, while the study sample was 209 respondents. The sampling technique used was proportional random sampling technique. The analysis were performed using the Chi-Square test. The results of statistical tests with chi-square obtained the value of land availability (p-value=0,000), knowledge (p-value=0,031), and income (p-value=0,000). It can be concluded that there is a relationship between land availability, knowledge, and income levels associated with low ownership of healthy latrines in the tidal area of ​​Lapulu Village, Kendari City. Therefore, it is hoped that the community and local government will establish this inter sector collaboration with related agencies to increase community ownership of healthy latrines.
