Published: April 2021

AbstractThe pressure on the universities to take a visible place in the rankings has caused anachronistic policies and practices in evaluating the performance of universities. The value attributed to the rankings results in policies prioritizing the criteria imposed by rankings while evaluating the performance of academics, which successively causes several issues in assessing the real impact of the academic practices. Considering these criticisms and concerns about the impact assessment, this study aimed at exploring the perceptions of academics about the impact of their academic practices. Adapting the interpretive phenomenological design, the data were collected through semi-structured interviews with 20 participants from the field of education in five flagship universities of Turkey. The findings of the study revealed that, although impact assessment understanding of the academics and their institutions go parallel with covering the practices around three basic missions of the university, many activities go in between without recognition by the same impact assessment practices. Interestingly, the academics exhibited their commitment to institutional policies in impact assessment practices; however, they exhibit resentment for the same policies due to failing to recognize the localized mission of the university, threatening the deeply rooted values of the academy, fouling the academy with ethical violations, and causing further detachment between academic practices and societal needs. The concerns and criticism of the current impact assessment are likely to alter the priorities of the universities and push them to adapt an impact assessment, which is less relevant to the local needs of their societies.

Abstract
We identify long-lived pricing errors through a model in which inattentive investors arrive stochastically to trade. The model’s parameters are structurally estimated using daily NYSE market-maker inventories, retail order flows, and prices. The estimated model fits empirical variances, autocorrelations, and cross-autocorrelations among our three data series from daily to monthly frequencies. Pricing errors for the typical NYSE stock have a standard deviation of 3.2 percentage points and a half-life of 6.2 weeks. These pricing errors account for 9.4$\%$, 7.0$\%$, and 4.5$\%$ of the respective daily, monthly, and quarterly idiosyncratic return variances.

Published: April 2021

Abstract
The purpose of this study was to investigate the challenges in comparing digital radiography (DR) systems from different vendors for various combinations of exposure factors in posterior–anterior hand radiographs. Image quality was evaluated for a range of tube voltages and tube current-time products using a technical contrast-detail (CDRAD) phantom and an anthropomorphic hand phantom. 900 technical CDRAD images were analysed providing quality figures of merit (IQFinv) and two experienced reporting radiographers using visual grading analysis (VGA) scored 108 anthropomorphic images. This study demonstrates the differences between the DR systems included. When compensating for variations in dose, Canon showed superior results for technical image quality and Fuji for visual image quality for a standard dose point at DR hand examination (ln(DAP) 1.1, 50 kV and 2.5 mAs).

Abstract

Introduction
In utero Zika virus (ZIKV) exposure has been related to a group of congenital structural abnormalities called the congenital Zika syndrome, which also has been related to neurodevelopment alterations even in normocephalic children. Physical growth has been less explored, and delayed growth and malnutrition have been reported.

Objective
The objective of this study is to describe the growth and neurodevelopment features of normocephalic infants born from a cohort of mothers with RT-PCR confirmed ZIKV during pregnancy in Risaralda, Colombia.

Methods
We conducted a retrospective cohort, including normocephalic children born from mothers with RT-PCR confirmed ZIKV infection during pregnancy in Risaralda, Colombia. Physical growth was measured using WHO standards, and neurodevelopment was measured with the abbreviated neurodevelopment scale 2 validated for Colombia.

Results
After verifying inclusion and exclusion criteria, 16 children were followed during a median time of 28 months (IQR 23–31 months); for a total of 116 visits, 87.5% (n = 14) of the patients developed a growth alteration. Five presented post-natal microcephaly, and among them, four presented malnutrition or low height. Six patients developed macrocephaly. Patients with a normal head circumference had normal neurodevelopment. Only one patient with microcephaly persisted with impairment of the neurodevelopment at the end of follow-up. All the patients with macrocephaly had normal neurodevelopment.

Discussion
Our study suggests that growth could be altered in infants with in utero Zika exposure. We found a high proportion of patients with overgrowth and macrocephaly. Future studies should consider endocrine follow-up of children born with in utero Zika exposure to explore these findings’ possible aetiologies.

Conclusion
We found a high proportion of growth alterations, particularly with overgrowth features and macrocephaly. Our study suggests that in addition to neurodevelopment impairment, growth could be altered in infants and children with in utero Zika exposure, even in those patients born without CZS.

Authors: Romano David M. , Hautala Gavin S. , Abbenhaus Eric J. , Aneja Arun , Moghadamian Eric S. , Wright Raymond D. , Sciadini Marcus F. , Matuszewski Paul E. 
Published: April 2021

Objective:
To assess the effectiveness of reducing contamination using 2 methods of C-Arm draping compared with traditional methods.

Materials and Methods:
The authors simulated an operating room using an extremity drape, commercially available C-Arm drapes, and C-Arm. A black light was placed above the field. A fluorescent powder was placed on the nonsterile portions of the field. Baseline light intensity was recorded by photo. The C-Arm was brought into the surgical field for orthogonal imaging for 15 cycles. A repeat photograph was taken to measure the increase in intensity of the fluorescent powder to assess degree of contamination. This was repeated 5 times for each configuration: standard C-Arm drape, a proprietary close-fitting drape, and a split drape secured to the far side with the split wrapped around the C-Arm receiver. Light intensity difference was measured and average change in intensity was compared.

Results:
Compared with standard draping, the proprietary close-fitting drape resulted in a 71.3% decrease in contamination (4.84% vs. 16.90%, P = 0.101) that trended toward significance and the split drape resulted in a 99.5% decrease (0.09% vs. 16.90%, P = 0.017) that was statistically significant.

Conclusion:
Far side contamination can be reduced by using a split drape connecting the operative table to the C-Arm receiver, effectively “sealing off” contaminants. The proprietary close-fitting drape may also decrease contamination, but this was not statistically significant in this study. Use of the split drape technique will help prevent contamination and may ultimately lead to decreased infection risk.
Maternal Cardiovascular Health and Adverse Childbirth Outcomes in the United States
Authors: Muchira James M. , Heelan-Fancher Lisa , Hayman Laura L. 
Published: April 2021

Background
Cardiovascular-related adverse childbirth outcomes have been increasing in the United States, with widening racial and ethnic disparities.

Objective
We examined the association between maternal cardiovascular health (CVH) and childbirth outcomes among US births.

Methods
We analyzed data from the Pregnancy Risk Assessment Monitoring System. Ideal CVH was defined as a composite of 4 cardiovascular disease (CVD) risk factors: absence of a medical diagnosis of diabetes, hypertension, history of cigarette smoking before or during pregnancy, and a pre-pregnancy body mass index of 18.5 to 24.9 kg/m2. Childbirth outcomes examined were preterm birth, low birthweight, and mode of birth. Survey logistic regression was used for multivariate analyses.

Results
A total of 34 918 women were included in our study, and most (61%) had more than 1 CVD risk factor. Clustering of CVD risk factors was more likely among women with an annual income of less than $40 000 and not college educated and found among non-Hispanic Black, Hispanic, and American Indian/Alaska Natives (P < .001). The odds of an adverse childbirth outcome increased with each additional CVD risk factor. Hypertension was highest among non-Hispanic Black women (20%) and the strongest predictor of having a low-birth-weight infant (odds ratio [OR], 3.16; 95% confidence interval [CI], 2.86–3.48), preterm birth (OR, 2.72; 95% CI, 2.40–3.07), and cesarean birth (OR, 1.68; 95% CI, 1.52–1.87).

Conclusion
Clustering of maternal CVD risk factors was significantly associated with adverse childbirth outcomes. Unfavorable CVH and its association with adverse childbirth outcomes were most common in women of color, calling for special attention to this group.

Abstract

Background
The recognition of emotions in facial expressions (REFE) is a core aspect of social cognition. Previous studies with the serotonergic hallucinogens lysergic acid diethylamide and psilocybin showed that these drugs reduced the recognition of negative (fear) faces in healthy volunteers. This trial assessed the acute and prolonged effects of a single dose of ayahuasca on the REFE.

Methods
Twenty-two healthy volunteers participated in a pilot, proof-of-concept, randomized trial. Study variables included a REFE task performed before and 4 hours after drug intake, subjective effects (self-reports/observer impressions), tolerability measures (cardiovascular measures, self-reports), and brain-derived neurotrophic factor plasma levels. The REFE task was applied again 1, 7, 14, and 21 days and 3 months after drug intake. Stability of ayahuasca alkaloids during the study was also assessed (room temperature, 18 months).

Findings
Compared with placebo, ayahuasca did not modify the REFE. No significant effects were observed on cardiovascular measures and brain-derived neurotrophic factor levels. Volunteers reported visual effects, tranquility/relaxation, and well-being, with few reports of transient anxiety/confusion. Ayahuasca was well tolerated, producing mainly nausea, gastrointestinal discomfort, and vomiting. A significant time-dependent deterioration of alkaloids was observed, especially for dimethyltryptamine.

Conclusions
Absence of significant effects on the REFE task could be due to lack of effects of ayahuasca (at the doses used), alkaloid degradation, learning effects, and the high educational level of the sample. Further trials with different samples are needed to better understand the effects of ayahuasca and other serotonergic hallucinogens on the REFE. Future trials should improve methods to guarantee the stability of ayahuasca alkaloids.
Awareness of Forensic Cases Among Nurses: A Descriptive, Cross-Sectional Study
Authors: Bektaş Gülfer , Pakiş Işıl 
Published: April 2021

ABSTRACT

Purpose
This study reports the knowledge, experience, and attitudes of nurses toward forensic cases in Turkey; critically evaluates the appropriateness of current practices in the collection and preservation of evidence; and assesses nurses' level of awareness on the law enforcement perspective of forensic cases. The study, thereby, seeks to offer solutions to some practical difficulties faced by nurses in clinical practice in Turkey.

Methods
The study involved 178 nurses of 202 employed in three healthcare centers operated by the same private healthcare group located in Istanbul, Turkey. The primary method of data collection was a questionnaire composed of three sections. The first section recorded data concerning the participants' age, gender, number of years spent in the profession, number of years spent in current workplace, department in which they worked, and their job title. The second section sought to assess the participants' academic background and, specifically, the extent of their educational training on forensic cases at the undergraduate and graduate levels. Finally, the third section aimed to assess the participants' knowledge of and approach toward the management of forensic cases in real-life time setting by collecting data on their previous experience with forensic cases.

Results
Of 178 nurses, 139 (78.1%) were female and 39 (21.9%) were male. The mean age was 28.6 years, ranging from 18 to 51 years. The participants expressed that they experienced difficulties in medicolegal procedures (21.9%), evidence collection (14.0%), history taking and preparation of the patient (10.1%), forensic case reporting (10.1%), registry (9.0%), and physical examination (7.9%). The level of knowledge of the collection of forensic evidence and the protection of wet evidence was statistically higher among the participants who previously received training on the collection, preservation, and transfer of forensic evidence versus those who were not previously trained (p < 0.001 for both).

Conclusion
Our study results highlight the need for medicolegal regulations and legislation allowing for the creation of specific positions for forensic nurses in Turkey. We also concluded that these nurses should be trained and equipped with necessary knowledge and skills in forensic nursing.
Evidence Collection and Analysis for Touch Deoxyribonucleic Acid in Groping and Sexual Assault Cases
Authors: Valentine Julie L. , Presler-Jur Paige , Mills Heather , Miles Suzanne 
Published: April 2021

ABSTRACT
Historically, evidence collection in sexual assault cases focused on obtaining foreign contributor bodily fluids through swab collection. With improvements in deoxyribonucleic acid (DNA) analysis methods, DNA profiles can be developed from touch DNA and applied to sexual assault cases. Following a literature review on factors affecting touch DNA transfer, a groping case study with innovative evidence collection is presented to support the expansion of touch DNA evidence collection in sexual assault cases. The groping case led to the development of a statewide sexual assault touch DNA form to guide evidence collection. DNA findings from additional groping sexual assault cases are reported to further show and justify the importance of evidence collection in groping cases. Implications on multidisciplinary practices are summarized to promote evidence collection and analysis in groping sexual assault cases. As forensic nurses are educated to accurately collect DNA evidence and provide trauma-informed, patient-centered care, they are best suited to provide nursing care for patients who have experienced groping sexual assaults. Optimal DNA findings in groping and sexual assault cases are best achieved through development of strong multidisciplinary, collaborative relationships between forensic nurses and forensic scientists.
Circulating miR-449a predicts survival outcome for colorectal cancer following curative resection
Authors: Fu Dengke , Chen Yang , Xu Dongkui 
Published: April 2021

Abstract
Previous studies showed that microRNA (miR)-449a may function as a tumor suppressor. However, the expression pattern and value of circulating miR-449a in colorectal cancer (CRC) remain unclear. Therefore, the purpose of this study was to measure circulating miR-449a level of CRC patients and evaluate its value for predicting prognosis.
Plasma samples of 343 consecutive CRC patients and 162 healthy controls were obtained. Circulating miR-449a levels were measured by using real-time quantitative reverse transcription polymerase chain reactions. All enrolled patients were followed up in a regular interval after surgery. The clinical data and survival outcome of all 343 patients were collected. The correlation between circulating miR-449a level and survival outcomes was analyzed by univariate and multivariate analysis.
Circulating miR-449a level in CRC patients was significantly decreased (P < .05) comparing with healthy controls. Low miR-449a was significantly associated with CEA and CA19-9 level (both P < .05). Furthermore, patients with a decreased miR-449a level had a lower 5-years overall survival (OS) rate than those with a high miR-449a (67.4% vs 76.9%, P = .03). Low circulating miR-449a level also been demonstrated as an independent risk factor for CRC in multivariate COX analysis (HR, 2.56; 95%CI: 1.15–8.63; P < .05).
Circulating miR-449a was significantly decreased in CRC patients and closely related to poor prognosis, suggesting that miR-449a might can be used as a useful diagnostic and prognostic marker for CRC.

Published: April 2021

Abstract
Myocardial strain analysis by 2D speckle tracking echocardiography could determine the left ventricular function. Our purpose is to investigate the global longitudinal strain (GLS) changes during the course of fulminant myocarditis (FM) and evaluate their correlation with cardiac magnetic resonance (CMR).
Patients with clinical diagnosis of FM from June 30, 2017 to June 30, 2019 were screened prospectively. 18 survived patients (mean age 34 ± 18 years) who had two scans of transthoracic echocardiography and underwent CMR were included.
All patients had severely impaired left ventricular ejection fraction and GLS value at admission that improved significantly before discharge. The patients in the healed stage revealed elevated global native T1 and T2 relaxation time and extracellular volume fraction as well, which were 1408.3 ± 88.3ms, 46.56 ± 5.23ms, and 0.35 ± 0.09, respectively. GLS from the second transthoracic echocardiography in the healed stage correlated significantly with global native T1 relaxation time (r =-0.574, P = .013) and with extracellular volume fraction (r = -0.582, P = .011), but not global native T2 relaxation time (r = -0.31, P = .211) and not with late gadolinium enhancement mass (r = 0.084, P = .743). In comparison, GLS at admission were not correlated with CMR parameters of fibrosis and oedema in the healed stage.
GLS by 2D-STE may emerge as a new tool to monitor inflammatory myocardial injuries during the course of FM. FM in the acute healed stage has the presence of both chronic fibrosis and oedema which are correlated with GLS, but GLS at admission can’t predict the early recovery of myocardial inflammation.
Disseminated ovarian granulosa cell tumor after laparoscopic surgery
Authors: Cui Man-Hua , Zhang Xi-Wen , Zhao Li-Ping , Liu Shu-Yan , Jia Yan 
Published: April 2021

Abstract

Rationale:
Granulosa cell tumors (GCT) have an incidence of 0.6 to 0.8/100,000. Short-term relapsed ovarian GCT is extremely rare. Herein, this report aims to present 2 rare cases of disseminated ovarian GCT and analyze the causes of recurrence.

Patient concerns:
The 2 patients presented with abdominal pain.

Diagnosis:
Both the patients were diagnosed with relapsed ovarian GCT (IIIc stage) in the adult type.

Interventions:
The 2 patients had a medical history of surgery for ovarian GCT by using laparoscopic with power morcellators (LPM). They experienced relapsed ovarian GCT postoperatively. Subsequently, they received a repeated operation through a laparotomy approach. Numerous malignant metastasis neoplasms were detected at the port-sites. Then, tumor resection was performed.

Outcomes:
The postoperative pathologies of both case 1 and case 2 reported ovarian GCT (IIIc stage) in adult type. The 2 patients presented disease-free survival for more than 33 months follow-up period.

Lessons:
The application of LPM may be a risk factor of disseminated ovarian GCT. However, laparoscopic surgery is still an optimal treatment strategy for ovarian tumors. Besides, gynecologists should comply with the tumor-free principle during surgery.

Abstract
Pediatric cases of coronavirus disease 2019 (COVID-19) have been reported. This meta-analysis was aimed at describing the clinical, laboratory, and imaging characteristics of children with COVID-19 based on published data of pediatric COVID-19 cases.
Search of PubMed, Embase, Web of Sciences, Science Direct, and Google Scholar for articles published until December 14, 2020, that described the clinical, laboratory, and imaging features of children with COVID-19. Data were extracted independently by 2 authors. Random-effects meta-analysis models were used to report pooled results.
Clinical data from 2874 children with COVID-19 from 37 articles were finally included for quantitative analyses. Fever (48.5%, 95% CI: 41.4%–55.6%) and cough (40.6%, 95% CI: 33.9%–47.5%) were the most common symptoms; asymptomatic infection and severe cases, respectively, accounted for 27.7% (95% CI: 19.7%–36.4%) patients and 1.1% of the 1933 patients included. Laboratory tests showed 5.5% (95% CI: 2.8%–8.9%) of the patients had lymphopenia. The pooled prevalence of leukopenia was 7.3% (95% CI: 3.4%–12.2%), and the C-reactive protein level was high in 14.0% (95% CI: 6.8%–22.8%). Chest computed tomography showed unilateral and bilateral lesions, and ground-glass opacity in 29.4% (95% CI: 24.8%–34.3%) and 24.7% (95% CI: 18.2%–31.6%), and 32.9% (95% CI: 25.3%–40.9%), respectively, and normal in approximately 36.0% (95% CI: 27.7%–44.7%).
We found that children with COVID-19 had relatively mild disease, with quite a lot of asymptomatic infections and low rate of severe illness. Data from more regions are needed to determine the prevention and treatment strategies for children with COVID-19.
