Abstract Objectives This review fills the paucity of information on K. pneumoniae as a nosocomial pathogen by providing pooled data on epidemiological risk factors, resistant trends and profiles and resistant and virulent genes of this organism in Asia. Methods Exhaustive search was conducted using PubMed, Web of Science, and Google scholar for most studies addressing the prevalence, risk factors, drug resistant-mediated genes and/or virulent factors of K. pneumoniae in Asia. Data extracted for meta-analysis were analyzed using comprehensive meta-analysis version 3. Trends data for the isolation rate and resistance rates were entered into Excel spread sheet and the results were presented in graphs. Results The prevalence rate of drug resistance in K. pneumoniae were; amikacin (40.8%) [95% CI 31.9–50.4], aztreonam (73.3%) [95% CI 59.9–83.4], ceftazidime (75.7%) [95% CI 65.4–83.6], ciprofloxacin (59.8%) [95% CI 48.6–70.1], colistin (2.9%) [95% CI 1.8–4.4], cefotaxime (79.2%) [95% CI 68.0–87.2], cefepime (72.6) [95% CI 57.7–83.8] and imipenem (65.6%) [95% CI 30.8–89.0]. TEM (39.5%) [95% CI 15.4–70.1], SHV-11 (41.8%) [95% CI 16.2–72.6] and KPC-2 (14.6%) [95% CI 6.0–31.4] were some of the resistance mediated genes observed in this study. The most virulent factors utilized by K. pneumoniae are; hypermucoviscous phenotype and mucoviscosity-related genes, genes for biosynthesis of lipopolysaccharide, iron uptake and transport genes and finally, adhesive genes. Conclusion It can be concluded that, antimicrobial resistant in K. pneumoniae is a clear and present danger in Asia which needs strong surveillance to curb this menace. It is very important for public healthcare departments to monitor and report changes in antimicrobial-resistant isolates.

Abstract Background: No available meta-analysis was printed to systematically introduce the MPNST clinic outcome and risk factors based on largely pooled data. This systematic review and meta-analysis aimed to investigate 5-year OS rate, 5-year EFS rate and LR rate for MPNST, and to assess potential risk factors for prognosis.Methods: Electronic articles published between January 1, 1966 and February 29, 2020, were searched and critically evaluated. The authors independently reviewed the abstracts and extracted data for 5-year OS rate, 5-year EFS rate, LR rate, and potential risk factors for prognosis.Results: Twenty-eight literatures were finally included for meta-analysis. The pooled 5-year OS rate, 5-year EFS rate, and LR rate were 49%, 37%, and 38%, respectively. The significant prognostic factors for survival were NF1 status, tumor size, depth, location, malignant grade, margin status, chemotherapy, and radiotherapy. Age and sex were not associated with survival.Conclusion: Survival and local recurrence of MPNST are poor. Worse prognosis is mainly associated with NF 1, large size, deep to fascia, high grade, metastases and location (trunk and head & neck). Complete resection with adequate surgical margins is the mainstay protective factor of MPNST patients, following necessary adjuvant therapies.

This study aimed to evaluate the risk factors for prognostic of post-stroke dementia (PSD). A systematic review included case-control and/or cohort studies, we searched both published and unpublished literatures between 2000 to July 31, 2016. Two authors independently screened and selected research articles. If another one disagreed, the third author would be just along with his/her professionally. Moreover, Critical appraisal was measured by the quality (GRADE). Data collection was in the data extraction form. The Rev-Man 5.3 was used to estimate pooled data. The fixed-effect model will be used when the heterogeneity I2>50%. Result eight publications were pooled for measuring an association between risk factors and PSD by meta-analysis. There were 6 strongly PSD risk factors. The pooled relative ratio (RR) of atrial fibrillation was 1.68, previous stroke 1.59, myocardial infarction 1.40, hypertension 1.36, diabetes mellitus 1.25 and previous transient ischemic attack 1.25 respectively. Un-pooled data from 13 publications reported that the risk factors for dementia in stroke patients were i) demographic factors, ii) vascular risk factors, iii) stroke factors, iv) stroke complications, and v) abnormalities on brain imaging. Strongly risk factors associated with increasing PSD risk were atrial fibrillation, previous stroke, myocardial infarction, hypertension, diabetes mellitus, and previous transient ischemic attack. Further studies, strongly risk factors need to investigate and develop the risk score for the prediction of dementia in stroke patients.

Age and sex were not associated with survival.Conclusion: Survival and local recurrence of MPNST are poor. Worse prognosis is mainly associated with NF 1 mutation, large size, deep to fascia, high grade, metastases and location (trunk and head & neck). Complete resection with adequate surgical margins is the mainstay protective factor of MPNST patients, following necessary adjuvant therapies.

ABSTRACT The concepts of billable hours and tracking time are a reality in public accounting. The purpose of this case is to educate students on the concept of billable hours and to improve the student's Excel skills through the development of a spreadsheet to track their time. Students were required to create the time-tracking Excel spread-sheet and to track all (personal and school-related) of their time for two weeks. Students were given pre/post tests and surveys and the results reflect that students significantly increased their performance in intermediate and advanced Excel skills, billable hours concepts and realize the difficulty in tracking time. Even though the students acknowledged the difficulty in tracking time, they did enjoy learning more about billable hours that they may encounter in their future professions.
