Factors related to use of prenatal screening tests at Hanoi Obstetrics and Gynecology Hospital in 2021

Purpose: To examine the rate of use of prenatal screening tests and the factors related to the use of prenatal screening tests in pregnant women at Hanoi Obstetrics and Gynecology Hospital. Participants and methods: A cross-sectional descriptive study was performed on 350 pregnant women who came for prenatal screening at Hanoi Obstetrics and Gynecology Hospital. Results: 62% of pregnant women performed fetal ultrasound; 59.1% used Double test. 20.6% and 28.6% of pregnant women performed Triple test and NIPT. Only 25.4% of pregnant women used prenatal screening test according to the correct gestational age. The results indicated that the factors related to the use of the prenatal screening test included age, academic level, times of pregnance, previous results of screening tests, counseling. Specifically, the participants in the age group older than 30 years old, with a university degree or higher using the prenatal screening tests were higher at 5.26 times and 3.08 times compared to younger and lower educated participants. The participants with the second time or more of pregnance, risks from previous test results and counseled for prenatal screening tests using prenatal screening tests were 3.80 times, 3.22 times and 2.57 times compared to the participants with the first pregnancy, the previous normal test results, and without prenatal screening test counseling. Conclusion: These findings suggested that nurses and health care providers who are responsible for pregnant women should pay more attention to strengthen health education, timely counseling to raise awareness of pregnant women, especially in the group of pregnant women over 30 years old, with low education level, abnormal previous test results about the importance of prenatal screening tests, to help pregnant women make the right decisions to take the right prenatal screening tests in protecting the health of both mother and fetus.
Behavioral Nudges to Improve Audit and Feedback Report Opening Among Antibiotic Prescribers: A Randomized Controlled Trial

Abstract Background Peer comparison audit and feedback has demonstrated effectiveness in improving antibiotic prescribing practices, but only a minority of prescribers view their reports. We rigorously tested 3 behavioral nudging techniques delivered by email to improve report opening. Methods We conducted a pragmatic randomized controlled trial among Ontario long-term care prescribers enrolled in an ongoing peer comparison audit and feedback program which includes data on their antibiotic prescribing patterns. Physicians were randomized to 1 of 8 possible sequences of intervention/control allocation to 3 different behavioral email nudges: a social peer comparison nudge (January 2020), a maintenance of professional certification incentive nudge (October 2020), and a prior participation nudge (January 2021). The primary outcome was feedback report opening; the primary analysis pooled the effects of all 3 nudging interventions. Results The trial included 421 physicians caring for >28 000 residents at 450 facilities. In the pooled analysis, physicians opened only 29.6% of intervention and 23.9% of control reports (odds ratio [OR], 1.51 [95% confidence interval {CI}, 1.10–2.07], P = .011); this difference remained significant after accounting for physician characteristics and clustering (adjusted OR [aOR], 1.74 [95% CI, 1.24–2.45], P = .0014). Of individual nudging techniques, the prior participation nudge was associated with a significant increase in report opening (OR, 1.62 [95% CI, 1.06–2.47], P = .026; aOR, 2.16 [95% CI, 1.33–3.50], P = .0018). In the pooled analysis, nudges were also associated with accessing more report pages (aOR, 1.28 [95% CI, 1.14–1.43], P < .001). Conclusions Enhanced nudging strategies modestly improved report opening, but more work is needed to optimize physician engagement with audit and feedback. Clinical Trials Registration NCT04187742.
Buprenorphine, a partial opioid agonist, prevents modulation of H-reflex induced by pulsed electromagnetic stimulation in spinal cord injured rats

Our recent study revealed that spinal electromagnetic stimulation (sEMS) applied at low (0.2Hz) frequencies may improve diminished transmission in damaged spinal cord in spinal cord injured (SCI) rats. We have recently begun a pilot study investigating the effects of sEMS in non-injured and SCI humans. One unexpected result was the reduction of chronic low back pain (CLBP), reported by some patients following sEMS treatment. Chronic low back pain is one of the main causes of disability affecting the general population. Opioids are the most common drugs prescribed to US adults with CLBP. To optimize parameters for sEMS for pain treatment, in this study we used the SCI animal model and examined effects of sEMS applied at lumbosacral level on parameters and frequency-dependent depression (FDD) of Hoffmann H-reflex responses, known as common neurophysiological measures for evaluation of sensorimotor condition and plasticity in humans. We have also examined the interactive effects of sEMS and the opiate partial agonist Buprenorphine on the parameters of H-reflex in naïve and SCI rats. Consistent with previous reports, chronic SCI resulted in a marked decrease of threshold intensity required to evoke H-reflex and a lesser rate of FDD of the H-response in adult rats. Our current study revealed the optimum parameters of spinal EMS for best recovery of the properties of the H-reflex in chronic SCI animals. Here we demonstrate that electro-magnetic stimulation applied at spinal L4-L5 level with a pulsed mode (pulse at 20 Hz frequency for 5 sec with 25 sec break between pulses, total 40 trains for 20 minutes; PSEMS) reversed effects of SCI on key parameters of H-reflex: i.e. (1) restored the threshold intensity of electric current applied at tibial nerve to evoke the H-reflex and (2) recovered FDD properties of the H-reflex in SCI rats. Importantly, subcutaneous injections of Buprenorphine, prior to PSEMS administration, abolished the ability of PSEMS to recover both threshold intensity and FDD of the H-reflex in chronic SCI animals. These results suggest that a semi-synthetic opioid Buprenorphine and PSEMS might share common sites of action. We thus conclude that PSEMS might carry potential as a non-invasive treatment approach for chronic low back pain.
Acute Appendicitis in Situs Inversus Totalis: A Case Report

Left-sided acute appendicitis (LSAA) is a rare cause of acute pain in the abdomen and is associated with developmental anomalies such as situs inversus (viscus) totalis (SIT) and midgut malrotation (MM). Due to the rarity along with the atypical presentation, diagnosis of LSAA is difficult, and if it is not managed timely, complications of appendicitis such as perforation can result. Imaging including contrast-enhanced CT scans and ultrasound aids in establishing the diagnosis. In case of a diagnostic dilemma, a diagnostic laparoscopy is an optimal option that offers diagnostic as well as therapeutic benefits. Operative intervention, preferably laparoscopic, is the standard treatment of LSAA. We report a case of appendicitis in a 36-year-old man with SIT detected radiologically who presented with pain in the left side of the lower abdomen for two days. Minimal tenderness was noted on the left iliac fossa during per abdominal examination. Abdominal ultrasonography was showing probe tenderness in the left iliac fossa, and contrast CT of the abdomen was suggestive of appendicitis with SIT. The patient was managed by laparoscopic appendicectomy. Therefore, we conclude that LSAA should be listed in the differentials of the various causes of left-sided pain in patients with SIT or MM. Clinical diagnosis is often difficult, and CT scan is crucial to establish the diagnosis as well as confirm rotational anomalies. Surgery, preferably laparoscopic, represents the appropriate treatment of LSAA.

Digital Compensatory Cognitive Training for Older Adults with Memory Complaints

ABSTRACT Many older people experience everyday memory complaints which can be a precursor condition to mild cognitive impairment and dementia. Research has consistently shown that compensatory cognitive training (CCT) benefits cognition in older adults. Providing CCT in a computerized format makes it more accessible and reduces its costs. We studied a newly developed digital CCT for older adults with everyday memory complaints that is multi-factorial and based on empirically supported techniques to improve memory. 55 older adults with self-reported everyday memory complaints participated in a study with outcomes assessed at baseline and post-intervention. We found that participants in the experimental condition improved significantly on the main objective outcome measure assessing associative memory compared to participants in a waitlist control condition. Specifically, after correcting for learning effects, 28% of participants in the experimental condition showed a reliable improvement. No effects were found on other objective outcome measures, most notably those assessing transfer to novel tasks. Participants in the experimental condition scored higher on measures of memory satisfaction, use of internal memory strategies, and quality of life. These findings contribute to existing knowledge on CCT by providing partial evidence for the efficacy of a digital CCT for older adults with everyday memory complaints. We recommend the use of digital CCT for older adults who experience memory complaints in their everyday life, but who do not qualify for medical treatment. Particular attention needs to be given to enhancing transfer of the learned strategies to everyday life.
Exploring the Moral Competencies of Gifted Students: Validation of Moral Competency Inventory - MCI

Starting from the modern understanding of giftedness as a domain-specific personality quality, research was conducted to determine the moral competencies of gifted students in different domains and to examine the psychometric characteristics of the adapted version of Moral Competency Inventory – MCI on a sample of 473 respondents. The results indicate that the original four-factor structure has been confirmed and that the MCI is a reliable and valid instrument suitable for application in other educational contexts as well. It was found that students gifted in different domains differ from each other when it comes to integrity and that this property is most developed in students gifted in the field of sports, then music, mathematics, and finally, visual arts. Such results indicate the importance and need for continuous professional guidance and intentional moral education of gifted students.
Melatonin Application Alleviates Stress-Induced Photosynthetic Inhibition and Oxidative Damage by Regulating Antioxidant Defense System of Maize: A Meta-Analysis

Melatonin is effective in modulating metabolism and regulating growth and development in many plants under biotic and abiotic stress. However, there is no systematic quantification of melatonin effects on maize growth, gas exchange, chlorophyll content, and the antioxidant defense system. A meta-analysis was conducted on thirty-two currently available published articles to evaluate the effect of stress types, study types, and maize varieties on response ratio (lnRR++) of “melatonin” to “control (no melatonin)” on plant growth, enzyme activities, gas exchange parameters, and photosynthetic pigments. Our findings revealed that melatonin application overall increased plant height, leaf area, root length, fresh and dry root weight and shoot weight, superoxide dismutase (SOD), peroxide (POD), catalase (CAT), ascorbate peroxidase (APX), soluble sugar and protein, photosynthetic rate, stomatal conductance, transpiration rate, chlorophyll, and carotenoid in maize leaf under stress conditions. In contrast, melatonin application decreased the levels of hydrogen peroxide (H2O2), superoxide anion (O2−), malondialdehyde (MDA), and electrolyte leakage. The categorical meta-analysis demonstrated that melatonin application to chilling stress resulted in higher SOD activity followed by salt stress. Melatonin application to all stress types resulted in higher POD, CAT and APX activities, except Cd stress, which had no effect on POD and decreased CAT by 38% compared to control. Compared to control, melatonin resulted in lower reactive oxygen species (ROS) and electrolyte leakage under no stress, Cd, drought, salt, lead, heat, and chilling stress in all study types (pot, growth chamber, hydroponic, and field), except O2 content which was not affected in pot and growth chamber studies. It was concluded that melatonin alleviates oxidative damage by improving stress tolerance, regulating the antioxidant defense system, and increasing leaf chlorophyll content compared to control.
Identifying difficulties of software modeling through class diagrams: A long-term comparative analysis

Software modeling is a creative activity in which software components and their relationships are identified based on customer requirements. Based on the literature, object-oriented software modeling is based on four fundamental pillars which are abstraction, encapsulation, decomposition, and inheritance. However, despite the existence of guidelines and recommendations for implementing the object-oriented approach, novice software designers do not make good design decisions, leading to inefficient designs that cannot be modifiable, understandable, or user-friendly distribute at the development level. The literature reveals that the most common difficulties faced by software designers is a lack of understanding and confusion of concepts related to the object-oriented approach, as well as difficulties in creating Unified Modeling Language diagrams, especially class diagrams. The work presented in this article uses a qualitative and quantitative approach to determine, in a group of university students, what are the most recurrent difficulties and their persistence during the time. The qualitative case study is the method that allowed to generate the documents: diagnostic and evaluation tests. Additionally, a thematic analysis was used to identify, analyze and report patterns within the data. In order to know the occurrences of the problems in the case study, as part of our quantitative approach, a comparative study was applied to compare the results obtained between the diagnostic and evaluation tests and thus establish the similarities and differences among the cases observed, through the hierarchical clustering technique. The findings of this study show us 16 difficulties identified after the qualitative analysis, while the quantitative analysis shows us the number of occurrences and their persistence over time. The difficulties reported in both analyzes focus on these three difficulties: a) Definition of attributes that could be a class, b) Classes with inadequate or insufficient behavior and, c) Incorrect use of multiplicity between classes. Each of these difficulties is analyzed in depth in this study.
Chen Software Reliability Growth Model

Software reliability analysis is very vital in software development. Software manufacturers assess the quality of their developed software through this analysis. This has triggered the development of reliability models. Software reliability growth models have been used extensively to examine the quality of manufactured software before they are sent to the market. This study presents a new software reliability growth model using Chen distribution. The Chen software reliability growth model is then used to establish sequential probability ratio test limits for determining whether a manufactured software is reliable or unreliable. The applications of the proposed model revealed that it performs better than some of the existing software reliability growth models for the given datasets.
PROPERTIES OF SOLID POLYURETHANES MADE FROM PALM OLEIN-BASED POLYOLS PREPARED WITH VARIOUS TYPES OF NUCLEOPHILES

Understanding on structure-property relationship between raw materials and resultant polyurethane (PU) products is very crucial in order to develop a product that is commercially feasible. This study is aimed to evaluate structure-property relationship of palm olein-based polyols in solid polyurethanes (SPUs). SPUs were prepared by reacting palm olein-based polyols (POoP) and 1,4-butanediol (BDO) with 4,4’-methylenebis(phenyl isocyanate) at a mole ratio of 1:1:2, respectively. Mechanical and thermal properties, phase interaction, crystallinity and solvent resistance of SPUs were evaluated. Mechanical properties and solvent resistance of SPUs were greatly influenced by hard segment concentration and crosslink density as witnessed in SPUs based on palm olein polyols made from water and methanol as nucleophiles. All SPUs are highly crystalline polymer (wide angle X-ray diffraction), thermally stable [thermogravimetric analysis (TGA)], exhibited phase-mixed morphologies between hard and soft segments [dynamic mechanical analyser (DMA)] and dimensionally stable in most solvents tested. In general, SPU made from POoP H (epoxide group of epoxidised palm olein ring-opened with water) offers high hardness and SPU made from POoP EG (epoxide group of epoxidised palm olein ring-opened with 1,2-ethanediol) offers good elongation and tear strength, exhibiting the most promising and economically feasible SPUs, depending on their target applications.
