Abstract
Background

Accurate inference of demographic histories of temperate tree species can aid our understanding of current climate change as a driver of evolution. Microsatellites are more suitable for reflecting recent historical events due to their high mutation rates. However, most programs analyze microsatellite data following a strict stepwise mutation model (SMM), which could cause false detection of population shrinkage when microsatellite mutation is not according with SMM.
Results

This study aims to reconstruct the recent demographic histories of five cool-temperate tree species, Quercus mongolica, Q. liaotungensis, Juglans cathayensis, J. mandshurica and J. ailantifolia, in eastern Asia by using 19 microsatellite markers and two methods considering generalized stepwise mutation model (GSM) (MIGRAINE and VarEff). Both types of software revealed that all populations experienced expansions after the Last Glacial Maximum (LGM). In particular, J. cathayensis experienced a more serious bottleneck in its history than the other species, leading to a smaller effective population of ancestors, while Q. mongolica showed only a moderate increase in population size and remained stable after the expansion. In addition, the point estimates of the multistep mutation proportion in the generalized stepwise mutation model (pGSM) in all populations were between 0.50 and 0.65, which indicates that when inferring population demographic history of the above forest species using microsatellite molecular markers, it is better to assume a GSM rather than a SMM.
Conclusions

This study provides the first direct evidence that five cool-temperate tree species in East Asia have experienced expansions after the LGM using microsatellites data. Moreover, since the mutation model of microsatellite have a vital influence on demographic inference, combining multiple software programs such as MIGRAINE and VarEff can effectively reduce unnecessary errors caused by inappropriate model selection and prior setting.

Abstract
It is important to determine the functional changes of organs that occur as a result of aging, the understanding of which may lead to the maintenance of a healthy life. Glucose metabolism in healthy bodies is one of the potential markers used to evaluate the changes of organ function. Thus, information about normal organ glucose metabolism may help to understand the functional changes of organs. [18F]-Fluoro-2-deoxy-2-D-glucose (18F-FDG), a glucose analog, has been used to measure glucose metabolism in various fields, such as basic medical research and drug discovery. However, glucose metabolism changes in super-aged animals have not yet been fully clarified. The aim of this study is to evaluate changes in glucose metabolism in organs and brain regions by measuring 18F-FDG accumulation and 18F-FDG autoradiography with insulin loading in super-aged and young wild-type mice. In control groups, the levels of 18F-FDG accumulation in the blood, plasma, muscle, lungs, spleen, pancreas, testes, stomach, small intestine, kidneys, liver, brain, and brain regions, namely, the cortex, striatum, thalamus, and hippocampus, were all significantly higher in the super-aged mice. After insulin loading, the 18F-FDG accumulation levels showed negative changes in the pancreas and kidneys, as well as in the cortex, striatum, thalamus, and hippocampus in the super-aged mice, whereas positive changes were observed in those in the young mice. These results demonstrate that insulin loading decreases effect on 18F-FDG accumulation levels in some organs of the super-aged mice. Therefore, aging can increase insulin resistance and lead to systemic glucose metabolism dysfunction.

Abstract
Introduction: Pediatric critical care patients with COVID-19 treated in Peru have higher mortality than those previously reported from other countries. Pediatric providers have reported a high number of patients without comorbidities presenting with hemorrhagic strokes associated with COVID-19. We present a study analyzing the factors associated with mortality in this setting.Methods: Prospective case-control study that included patients < 17 years old admitted to a pediatric critical care unit with a positive test confirming COVID-19. The primary outcome was mortality, and secondary outcomes were laboratory results and length of stay. Fisher’s exact test and the Mann-Whitney U test were used for the analysis.Results: Forty-seven patients were admitted to critical care. The mortality of our study is 21.3%. The mortality of patients with neurological presentation was 45.5%, which was significantly higher than the mortality of acute COVID-19 (26.7%) and MIS-C (4.8%), p 0.18. Other risk factors for mortality in our cohort were strokes and comorbidities. Only one patient presenting with hemorrhagic stroke had an undiagnosed comorbidity.Conclusion: Cerebrovascular events associated with COVID-19 in pediatric patients, including infants, must be recognized as one of the more severe presentations of this infection in pediatric patients.

Published: December 2020

Abstract
Background: Sarcomas, cancers originating from mesenchymal cells, are comprehensive tumors with poor prognoses, yet their tumorigenic mechanisms are largely unknown. In this study, we characterize infiltrating immune cells and analyze immune scores to identify the molecular mechanism of immunologic response to sarcomas.Method: The “CIBERSORT” algorithm was used to calculate the amount of L22 immune cell infiltration in sarcomas. Then, the “ESTIMATE” algorithm was used to assess the “Estimate,” “Immune,” and “Stromal” scores. Weighted gene co-expression network analysis (WGCNA) was utilized to identify the significant module related to the immune therapeutic target. Gene ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed using the “clusterProfiler” package in R for annotation and visualization. Results: Macrophages were the most common immune cells infiltrating sarcomas. The number of CD8 T cells was negatively associated with that of M0 and M2 macrophages, and positively associated with M macrophages in sarcomas samples. The clinical parameters (disease type, gender) significantly increased with higher Estimate, Immune, and Stromal scores, and with a better prognosis. The blue module was significantly associated with CD8 T cells. Functional enrichment analysis showed that the blue module was mainly involved in chemokine signaling and the PI3K-Akt signaling pathway. CD48, P2RY10 and RASAL3 were identified and validated at the protein level. Conclusion: Based on the immune cell infiltration and immune microenvironment, three key genes were identified, thus presenting novel molecular mechanisms of sarcoma metastasis.

Abstract
Background: CD14 is an important pattern recognition receptor having innate immune function and has antibacterial activity. It binds with LPS of gram-negative bacteria, arachidonic acid, and lipoteichoic acid. Being a receptor, it binds with the pathogen with the help of other cytokines. Mutations in CD14 affect the binding ability which in turn affects the biological potentiality. Method: The present study was conducted on 228 nos. of buffaloes pertaining to four different breeds as Murrah, Mehsana, Surti and Bhadawari. CD14 gene was characterized and polymorphism was detected through Single nucleotide conformation polymorphism. Association study was conducted for different variants of CD14 with mastitis in buffalo, detected through somatic cell count, california mastitis test.Result:Eight variants of CD14 were detected and mutational hotspots were detected in bubaline CD14 with 58 number of non-synonymous SNP, out of which 18 were observed to be deleterious and 34 as thermodynamically unstable. In the present study, we had detected the mutations in CD14 gene and its association with the somatic cell score and other indicators for mastitis. In-silico studies were conducted to understand the molecular mechanism how the mutations affect the biological potentiality by analyzing different domains and structural analysis along with various post-translational modification sites.Conclusion: Deleterious mutations were observed in CD14 gene which have significant effect on mastitis of buffalo. It may be employed for marker assisted selection, therapeutic application of recombinant CD14, gene therapy, transgenic or gene edited animal production with wild type CD14 resistant to mastitis as future strategy.

Abstract
Background: Current principles of postoperative pain management are primarily based on the types and extent of surgical intervention. This clinical study measured patient’s self-anticipated pain score before surgery, and correlated the scores with the pain levels and analgesic requirements after surgery.Methods: This prospective observational study recruited consecutive patients who received elective surgery in the E-Da Hospital, Taiwan from June to August 2018. Patients were asked to subjectively rate their highest anticipated pain level (numerical rating scale, 0-10) for the scheduled surgical interventions during their preoperative anesthesia assessment. After the operation, the actual pain intensity (NRS 0-10) experienced by the patient in the post-anesthesia care unit and the total dose of opioids administered during the perioperative period were recorded. Pain scores ³4 on NRS were regarded as being unacceptable levels for anticipated or postoperative pain.Results: A total of 996 patients were included in the study. Most of the patients (86%) received general anesthesia and 73.9% of them had a history of previous operation. Female anticipated significantly higher overall pain intensities than the male patients (adjusted odd ratio 1.532, 95% confidence interval 1.125-2.086; P=0.007). Patients who took regular benzodiazepine at bedtime (P=0.040) and those scheduled to receive more invasive surgical procedures were most likely to anticipate for higher pain intensity at the preoperative period (P<0.001). Although higher anticipated pain scores (NRS³4) were associated with higher postoperative pain levels (P=0.021) and higher total equivalent opioid dose (P=0.001) for acute pain management during the perioperative period, these surgical patients actually experienced less pain than they anticipated at the post-anesthesia care unit.Conclusion: This observational study found that patients who are female, use regular benzodiazepines at bedtime and scheduled for more invasive surgeries anticipate significantly higher surgery-related pain. Therefore, appropriate preoperative counseling for analgesic control and the management of exaggerated pain expectation in these patients is necessary to improve the quality of anesthesia delivered and patient’s satisfaction.

Abstract
Objectives: To evaluate the efficacy of oral clonazepam versus oral lorazepam following initial parenteral benzodiazepine administration to control methamphetamine-induced agitation in children. Methods: In a single-center clinical trial, intravenous diazepam (0.2 mg/Kg) was initially administered to all methamphetamine-poisoned pediatric patients to control their agitation, followed by a single dose of oral clonazepam (0.05 mg/Kg; n=15) or oral lorazepam (0.05 mg/Kg; n=15) to prevent relapse of toxicity. Results: The median age [IQR] (range) was 15 [ 10, 36] (6-144) months. The source of poisoning was methamphetamine exposure from oral ingestion in 23 (76.7%) and passive inhalation in 7 (23.3%) patients. The most common symptoms/signs were agitation (29; 96.7%), mydriatic pupils (26; 86.7%), and tachycardia (20; 66.6%). Two in each group (13.3%) needed re-administration of intravenous diazepam due to persistent agitation. There was no report of benzodiazepine complications in either group. Conclusions: Clonazepam and lorazepam treatment was equally effective at similar doses. However, considering the higher potency of clonazepam, it seems that lorazepam is the safer benzodiazepine for oral maintenance treatment of methamphetamine-induced agitation in children and can be used with minimal complications.

Published: December 2020

Abstract
Background Anxiety among women in the perinatal period is common. Assessing the severity of perinatal anxiety will help monitor the progress of the patient through the stages of anxiety and facilitated the treatment. This study assesses the validity and reliability of the “Perinatal Anxiety Screening Scale” (PASS) in the Arabic language. Methods The PASS was translated into Arabic. 217 women in the antenatal and postnatal phase participated (92 antenatal and 125 postnatal) answered to PASS, GHQ12, EPDS-10, and DASS-21. Content validity, factor analysis, internal consistency, and test retest reliability were assessed. Results Content Validity Index (CVI) and Content Validity Ratio (CVR) were .88 and 0.79; respectively. The scale loaded on four components: acute anxiety, social anxiety, and dissociation; specific fears and trauma; general anxiety and adjustment; and perfectionism and control. Cronbach’s Alpha value for the scale was 0.78 and test retest correlation coefficient was 0.94. PASS significantly correlated with EPDS-10 (rho=0.46), GHQ-12(rho=0.58), the three components of DASS-21 (0.47, 0.50, and 0.43; respectively), and experiencing adverse life events Conclusion The Arabic translated version of the PASS showed reasonably adequate validity and reliability and can be used to screen for anxiety disorder among women in the perinatal phase.

Published: December 2020

Abstract
Background. Medical students face significant stressors related to the intense rigors of their training and education. Accurate measurement of their stress is important to quickly identify, characterize and ameliorate these challenges. Existing measures have limitations that modern measurement approaches, such as item response theory (IRT), are able to address. This study presents the calibration and validation of a new IRT-based measure called the Medical Student Stress Scale (MSSS).Methods. Following rigorous measurement development procedures described elsewhere, the authors created and tested a pool of 35 items with 348 1st – 4th year medical students along with demographic and external validity measures. Psychometric analysis included exploratory and confirmatory factor analyses, IRT modeling, and correlations with legacy measures.Results. Of the original 35 items, 22 were retained based on their ability to discriminate, provide meaningful information, and perform well against legacy measures. The MSSS differentiated stress scores between male and female students, as well as between year in school.Conclusion. Developed with input from medical students, the MSSS represents a student-centered measurement tool that provides precise, relevant information about stress and holds potential for screening and outcomes-related applications.
Descriptive study of how proportioning marks determines the performance of nursing students in a pharmacology course.
Authors: Doggrell Sheila 
Published: December 2020

Abstract
Background: In programs with higher proportions of marks allocated to ongoing assessment, the students have higher overall marks than those with a lower proportion allocated to assessment. Little or no attention has been made to how the allocation affects the academic success of students in individual courses. The purpose of this study was to determine how the allocation of marks to examinations, tutorials and an assignment affects the performance of nursing students in a pharmacology course. Methods: For students who passed a pharmacology course (i) the marks for examinations and ongoing assessment (tutorials and/or an assignment) were compared, and (ii) regression line and correlation analysis was undertaken to determine any association between these marks. In addition, for completing students, modelling was undertaken to determine the effects of changing the allocation of marks on passing and failing rates. Results: Nursing students who passed a pharmacology course obtained significantly lower marks in examinations than ongoing assessment, and for the ongoing assessment, lower marks in the assignment than tutorials. Regression line analysis showed that the marks in ongoing assessment (tutorials and/or the assignment) versus examination marks were a poor line-fit. The correlation coefficients between ongoing assessment and examinations were weak to moderate. A high percentage of students passed the course (> 90%) and, modelling for completing students, showed that decreasing the marks for examination would have led to slightly more students passing the pharmacology course with higher grades. In contrast, increasing the marks for examination would have dramatically decreased the number of students passing the course, and their grades. Conclusions: The allocation of marks can have a major effect on student performance. As ongoing assessment is only a weak or moderate indicator of performance in examination this has implications for students who rely on passing examinations for their advancement. For instance, nursing students in some countries (e.g. USA) are required to pass examinations prior to registration, whereas in others (e.g. Australia) they are not. Consideration needs to be given as to whether it is appropriate for nursing students who fail examinations to pass courses/programs.
Quality of Nursing Education Programme in the Philippines: Faculty Members Perspectives&nbsp;
Authors: Appiah Stella 
Published: December 2020

Abstract
Background: The subject of continuous improvement in the quality of nursing education programme is an extremely sensitive issue worldwide, particularly in the Philippines where a high number of trained registered nurses are exported to both developed and developing countries. The assessment of the quality of nursing education programme is usually measured using pass rates in licensure examinations by several government organizations. However, few studies have indicated that various categories of faculty members view the quality of nursing programmes differently, this study probed further and determined whether the quality of nursing education programme differs according to the profile of faculty members in Philippines colleges of higher education. Methods: A cross-sectional survey study design was employed in this study. One hundred and eight-five (185) faculty members in fifteen (15) higher educational institutions were selected for the research using purposive-census sampling. The study was carried out from January 1 to June 30, 2017. Close-ended structured questionnaires based on study objectives were used to collect data. Frequency and percentages were used to analyse the profile of faculty members whereas weighted means from a four Likert’s scale was used to interpret the extent of perceived quality of nursing education programme.Results: Majority, 39% and 46% of faculty members had 1-5 years’ clinical experience and 6-10 years of teaching experience respectively. Faculty members strongly agreed with a grand weighted mean of 3.84 out of 4.00 that nursing education programme is of good quality in the Philippines and is synonyms with other universities in the world. Teaching experience of faculty members showed significant relations in the quality of mission/vision/goals/objectives (p-value=0.008), curriculum and instruction (p-value=0.038), administration of nursing programme (p-value=0.025), faculty development programme (p-value=0.003), physical structure and equipment (p-value=0.016), student services (p-value=0.017), admission of students (p-value=0.010) and quality assurance system (p-value=0.009).Conclusion: Faculty members strongly perceived nursing education programme to be of good quality in this study. Teaching experience of instructors showed a significant relationship with the quality of nursing education programme in all the quality assessment indicators. However, clinical experience and job category of faculty members rather showed that the quality of nursing education programme is the same throughout all the higher educational institutions. The study implies that the teaching experience of faculty members is a strong predictor of quality of nursing education programme and employing faculty experienced in teaching is substantial for the continuous improvement of nursing education programme.
