Authors: Hu Bo , Yang Xiao-Bo , Sang Xinting
Published: February 2020

Background: Hepatocellular carcinoma (HCC) is one of the deadliest malignancies. Currently, there is still a lack of effective treatment. Our purpose was to develop an immune-related prognosis lncRNA signature with regard to HCC.Methods: A total of 14,142 lncRNAs and 331 immune genes were obtained from The Cancer Genome Atlas (TCGA) and the Molecular Signatures Database to construct the immune-related lncRNAs co-expression networks. Moreover, the tumor samples collected from TCGA were randomized as training set and testing set, among which, the testing set and the entire set were used for verification. Subsequently, gene set enrichment analysis (GSEA) and principal component analysis (PCA) were employed for functional annotation.Results: An immune-related signature consisting of AC015908.3, AC068987.4 and AL365203.2 was identified among HCC patients. Under different conditions, patients in low-risk group exhibited longer overall survival (OS) than those in high-risk group (P < 0.001). Moreover, the as-constructed signature was an independent factor, which showed marked association with patient OS (P < 0.001, hazard ratio (HR) = 1.407). These findings were further validated in testing set and the entire set. Additionally, GSEA results revealed the different immune states between low-risk and high-risk groups. On the other hand, lncRNA-related mRNAs were also extracted to depict the networks.Conclusion: Our findings indicate that the three-lncRNA immune-related signature shows prognostic value for HCC.
Progesterone regimen impact on live birth rate and neonatal outcomes in artificial frozen-thawed embryo transfer cycles: a retrospective cohort study
Authors: Liu Yuan , Wu Yu
Published: February 2020

Background: Previous studies have demonstrated that singletons from frozen embryo transfer (FET) are heavier and longer-gestational-days at delivery than those from fresh embryo transfer. The amounts and routes of progesterone used in FET vary tremendously among different ART centers. Does different serum progesterone level induced by different progesterone regimens determine live birth rate and neonatal outcomes in hormone replacement therapy frozen-thawed embryo transfer (HRT-FET) cycles? Design: A cohort study of 856 HRT-FET cycles from a Chinese public fertility center. Data from patients undergoing their first FET cycles from 2015-2018 were extracted from the database. All patients had their first FET with two day2 or day3 embryos transferred. Endometrial preparation was performed with sequential administration of estrogen followed by progesterone 60mg per day intramuscularly or Crinone 90mg per day vaginally. Live birth was the primary outcome. Secondary outcome included clinical pregnancy rate, singleton birthweight, large for gestational age (LGA) rate, SGA rate and preterm delivery rate. Student’s t test, Mann-Whitney U-test, Chi square analysis and multivariable logistic regression were used where appropriate. Differences were considered significant if p<0.05. Results: No significant difference of live birth rate was found between different progesterone regimens (Adjusted OR 1.128, 95%CI 0.842, 1.511, p=0.420). Neonatal outcomes like birthweight, preterm delivery rate, SGA and LGA rate were not different between two progesterone regimens. Serum P level >41.82 pmol/L at 14 day post-FET was associated with higher live birth rate than serum P level ≤41.82pmolL in HRT-FET cycles when progesterone was intramuscularly delivered (Adjusted OR 1.690, 95%CI 1.002, 2.849, p=0.049). Birthweight and gestational weeks were not different between these two different P level groups. Conclusions: Progesterone vaginally or intramuscularly didn’t impact live birth rate and neonatal outcomes in artificial FET cycles. Relatively higher serum progesterone level induced by intramuscular regimen did not increase newborn birthweight or prolong gestational weeks compared to vaginal regimen. Intramuscular progesterone supplementation during HRT-FET cycles was associated with improved live birth rate when progesterone concentration at day 14 post-FET was higher than 41.82pmol/L.

Published: February 2020

Background High quality serious illness communication requires good understanding of patients' values and beliefs for their treatment at end of life. Natural Language Processing (NLP) offers a reliable and scalable method for measuring and analyzing value- and belief-related features of conversations in the natural clinical setting. We use a validated NLP corpus and a series of statistical analyses to capture and explain conversation features that characterize the complex domain of moral values and beliefs. The objective of this study was to examine the frequency, distribution and clustering of morality lexicon expressed by patients during palliative care consultation using the Moral Foundations NLP Dictionary.Methods We used text data from 231 audio-recorded and transcribed inpatient PC consultations and data from baseline and follow-up patient questionnaires at two large academic medical centers in the United States. With these data, we identified different moral expressions in patients using text mining techniques. We used latent class analysis to explore if there were qualitatively different underlying patterns in the PC patient population. We used Poisson regressions to analyze if individual patient characteristics, EOL preferences, religion and spiritual beliefs were associated with use of moral terminology.Results We found two latent classes: a class in which patients did not use many expressions of morality in their PC consultations and one in which patients did. Age, race (white), education, spiritual needs, and whether a patient was affiliated with Christianity or another religion were all associated with membership of the first class. Gender, financial security and preference for longevity-focused over comfort focused treatment near EOL did not affect class membership.Conclusions This study is among the first to use text data from a real-world situation to extract information regarding individual foundations of morality. It is the first to test empirically if individual moral expressions are associated with individual characteristics, attitudes and emotions.

Authors: Garcia Julie , Ichai Carole , Quintard Herve
Published: February 2020

Background In France, death after decision to withdrawal or withholding sustaining life therapies concerns about 10% of intensive care unit (ICU) patients. Clayes-Leonetti law published in 2016 intend to frame our medical exercise. The purpose of this study is to review the current practice concerning end of life (EOL) management in French ICU. Methods Two national surveys were conduct, the first one consisted in 30 multiple choices questions about epidemiology, EOL decisions making, care organization and self-opinion sent by mail to senior physicians members of “Société Française d’Anesthésie Réanimation (SFAR)”. Evaluation of practices on analgesia and sedation was conduct with two clinical cases. The second survey consisted in 24 multiples choices questions sent by mail to residents members of “SFAR jeunes”. Results Between October 2016 and October 2017, 695 physicians participated to the study. They majority work in a medico surgical unit in an University Center. Withholding and withdrawal life sustaining therapies decisions occur after collegial meeting (88%), a third doesn’t report decision in medical record, 46% always include medical third in decision making and only a third of physicians collect anticipate directive. Majority of them continue support care on these patients. In half of cases they haven’t sedation and analgesia protocol. Only 5% of physicians are completely satisfied of EOL care, where a better pain monitoring support is expected. Conclusion Heterogeneity for EOL management is important between physicians, we need to improve care and set up protocols to help physicians particularly concerning analgesia and sedation.

Authors: Huang Ziying , Li Qianqian , Li Mengxun , Li Changchun
Published: February 2020

Background The difference between the skeletal muscle growth rates of Western and domestic breeds is remarkable, but the potential regulatory mechanism involved is still unclear. Numerous studies have pointed out that long intergenic noncoding RNA (lincRNA) plays a key role in skeletal muscle development. This study used published Yorkshire (LW) and Tibetan pig (TP) transcriptome data to explore the possible role of lincRNA in the difference in skeletal muscle development between the two breeds. Results Through differential expression analysis, 138 differentially expressed lincRNAs (DELs) were obtained between the two breeds, and their potential target genes (PTGs) were predicted. The results of Gene Ontology and pathway analysis revealed that PTGs are involved in multiple biological processes and pathways related to muscle development. The quantitative trait loci (QTLs) of DELs were predicted, and the results showed that most QTLs are related to muscle development. Finally, we constructed a co-expression network between muscle development related PTGs (MDRPTGs) and their corresponding DELs on the basis of their expression levels. The expression of DELs was significantly correlated with the corresponding MDRPTGs. Also, multiple MDRPTGs are involved in the key regulatory pathway of muscle fiber hypertrophy, which is the IGF-1-AKT-mTOR pathway. Conclusions In summary, multiple lincRNAs that may cause differences in skeletal muscle development between the two breeds were identified, and their possible regulatory roles were explored. The findings of this study may provide a valuable reference for further research on the role of lincRNA in skeletal muscle development.

Published: February 2020

Background Recently, copeptin and nesfatin-1 have been identified as interesting novel peptides playing a role in the pathogenesis of obesity-related insulin resistance in adults, respectively. However, the relationship between them has not been elucidated; and their circulating levels in obese children have not been adequately studied. Therefore, the current study aimed to investigate whether their levels are altered in Chinese obese children and to study the correlation of these two peptides with each other and with insulin resistance and other biochemical parameters. Methods A total of 120 children were enrolled in this study, including 80 obese children and 40 lean controls. Anthropometric parameters and clinical data of all subjects were collected and circulating TNF-α, adiponectin, leptin, copeptin and nesfatin-1 levels were detected using enzyme-linked immunosorbent assays. Results Serum copeptin and nesfatin-1 levels were significantly elevated in obese children and children with insulin resistance compared to control subjects. In addition, nesfatin-1 and copeptin levels were found to be significantly positively correlated with one another in pearson’s correlation and partial correlation. More importantly, multiple regression analysis used nesfatin-1or copeptin as the dependent parameters and significant correlation between nesfatin-1 and copeptin with each other and the associations between each of them with HOMA-IR were detected. Conclusion These findings are novel and shed light on the possible interplay role of these two molecules in obesity-related insulin resistance.

Published: February 2020

Background Developing clinical and biomedical science faculty to become effective teachers is critical to meet the challenges of medical education. Education research is at a stage in which we have strong theories of student learning, but we do not have well-developed ideas about teacher learning, nor about how to help teachers incorporate new ideas into their ongoing systems of practice. We aim to study the AOSpine Faculty Development program, which consists in a series of training programs at progressive levels. Methods Retrospective study from a prospective database. The information for Faculty performance (national, regional and international) in all AOSpine educational events from 2008 to 2016 was retrospectively reviewed. Additionally we developed a supplementary survey with the participants in 2016. It covered demographic topics and 4 specific questions regarding (1) quality expectations for CME programs, (2) AOSpine events highlights, (3) what could be improved in AOSpine events, and (4) activities of interest. Results We’ve accessed scores from 646 professionals (n=646) in 7,962 evaluations from 2008 to 2016 using a five-point Likert scale. 798 participants replied the 2016 survey from 20 countries of the region. The evaluation for a national Faculty was 4.42 points, the regional 4.56, and for the international faculty 4.53. The mean punctuation for the master course was 4.25, for advanced 4.44, and the value of 4.48 for principles. The Chair Training promoted an increase of the evaluation from 4.44 to 4.52 (p = 0.022) Conclusion The appliance of a Faculty Development Program based on educational strategies directly affects the outcomes of educational events. The 8-years systematic review showed continued improvement of the trained faculty evaluations in all levels.

Published: February 2020

The key tasks of Ukrainian companies in foreign markets are determined in the article on the basis of analysis of the actual problems of foreign economic activity. The technologies of Ukrainian companies (especially small ones) entering foreign markets are quite costly and organizationally complex. Even a once successful strategy of foreign economic activity needs continuous improvement and adjustments in line with changes in the external business environment. Priority areas, innovations, and improvements that will contribute to improving the competitive position of Ukrainian companies in foreign markets include: professional (competence, knowledge, experience), logistics (the basis of supply in foreign trade contracts), insurance (exchange rate risks), financial (currency deregulation), institutional (attraction of external investments), customs (electronic declaration), and technological. The study proved that in a competitive environment, a commercially successful strategy of foreign economic activity of Ukrainian companies can be secured through intensification of technology transfer; increase in the volume of high-tech goods trade and exports of goods (services) with high added value; use of advantage of free trade agreements; increase in exports of organic farming products; strengthening the procedures for protecting intellectual property. These components are characterized by the significant potential for increasing the competitiveness of national companies in foreign markets. Taking into account resource opportunities of Ukrainian companies and external challenges (economic, geopolitical, technological, investment), the strategic task is gradual, but the irreversible shift of trade flows from the CIS countries to the European and Asian market.

Published: February 2020

The paper investigates theoretical and applied principles to determine the conditions for the introduction of the targeting regime in the government instruments system of economic and social development. This paper determines the key factors influencing the development of state-targeted programs, and analyzes the main weaknesses in the organization of its implementation. The paper suggests stages of monitoring based on the targeting regime, taking into account the stages of development and implementation of state target programs. We have developed the conceptual principles of the introduction mechanism of the targeting regime in the implementation of state target programs. The paper demonstrates the imperfection of the domestic system to implement the program-target method compared with its use in the European countries in terms of management and assessment of programs. An important aspect of the success to apply the targeting regime is the availability of a proper legal and regulatory framework that controls the main provisions of its implementation, the purpose of which is to ensure consistency of the indicator both at the strategic and operational levels and at the national, regional, sectoral levels. The object of monitoring at the final stage of the state target programs implementation is the target level, calculated on the basis of achieved indicators. The article states that the monitoring on the basis of the state target program targeting regime allows them to rank their priority in quantitative (target level taking into account spatial and temporal constraints) and qualitative aspects (compliance with the basic and additional conditions of the economic potential of the national economy). Also, monitoring based on the targeting regime allows the formation of an approved list of state target programs, which will be implemented first and foremost. The paper concludes that for the methodological support of the target regime introduction it is necessary to assess the real conditions that determine the development of the economic potential of the Ukrainian economy at the present stage.

Published: February 2020

The combination of nanotechnology and microfluidics may offer an effective water and wastewater treatment. A novel approach combines the use of magnetic particles which can capture heavy metal impurities in microfluidic ducts. The purpose of this study is to investigate the mixing mechanism of two water streams, one with magnetic particles and the other with wastewater. The optimum mixing is obtained when particles are uniformly distributed along the volume of water in the duct for the combined action of a permanent, spatially and temporally aligned magnetic field. Results showed that mixing is enhanced as the frequency of the magnetic field decreases or its amplitude increases, while magnetic gradient is found to play an insignificant role in the present configuration. Moreover, for simulations with low frequency, the mean concentration of particles is found to be twice as high as compared to the cases with higher frequency. Optimum distribution of particles inside the micromixer is observed for the combination of 0.6 T, 8 T/m and 5 Hz for the magnetic magnitude, gradient and frequency, respectively, where concentration reaches the optimal value of 0.77 mg/mL along the volume of the duct.

Published: February 2020

The performance of a new type of X-band weather radar (WR) for Sweden during a pilot run is studied. Compared to the conventional C-band WRs, the X-band WR covers a smaller area but with a higher spatiotemporal resolution, making it suitable for urban hydrological applications. Rainfall estimations from different elevation angles of the radar (levels) are compared at one-minute and single-event timescales with the observations of several rain gauges at different ranges using hyetographs. In general, the estimations aligned well with observations and the best match appeared for ranges as long as 5–10 km. Seemingly, radar estimations suffered from overshooting of lower lying showers by higher level scans in longer ranges (19–30 km) and from the reflectivity contamination due to moving objects in short ranges (<1 km). Also, the effective range of the radar dropped sharply for the moments when a cloudburst was located over the radar. Although various sources of error could affect the X-band WR rainfall estimates, higher resolution spatiotemporal rainfall monitoring for wider areas will benefit from an integration of data from a network of X-band WRs.

Published: February 2020

The optimum selection of the appropriate radiolabelled probe for the right target and the right patient is
the foundation of theranostics in personalised medicine. In nuclear medicine, this process is realised through the
appropriate choice of radiopharmaceuticals based on molecular biomarkers regarding molecular imaging. Theranostics
is developing a strategy that can be used to implement accepted tools for individual molecular targeting,
including diagnostics, and advances in genomic molecular knowledge, which has led to identifying theranostics
biomaterials that have the potency to diagnose and treat malignancies. Today, numerous studies have reported on
the discovery and execution of these radiotracers in personalised medicine. In this review, we presented our point
of view of the most important theranostics agents that can be used to treat several types of malignancies. Molecular
targeted radionuclide treatment methods based on theranostics are excellent paradigms of the relationship
between molecular imaging and therapy that has been used to provide individualised or personalised patient care.
Toward that end, a precise planned prospective examination of theranostics must be done to compare this approach
to more standard therapies.

Authors: Soydan Levent , Demir Ali Aslan , Torun Mehmet , Cikrikcioglu Makbule Arar
Published: February 2020

Background:

The apparent diffusion coefficient (ADC), the quantitative parameter of
diffusion-weighted magnetic resonance imaging (DW-MRI), is a measure for this restricted diffusion,
and its role in gastric cancer (GC) including distinguishing malignant segments from healthy
gastric wall, metastatic perigastric lymph nodes from benign nodes and evaluating response of GC
to neoadjuvant chemotherapy has been investigated in previous studies. Evidence suggests that
ADC may also be of help in assessment of aggressiveness and preoperative staging of gastric cancer,
which needs to be explored in further studies.

Objective:

To investigate the role of DW-MRI and its quantitative parameter, ADC in staging of
gastric cancer.

Methods:

Forty-six patients (28 male, 18 female, mean age 62 years) with non-metastatic biopsy-
proven GC who underwent abdominal DW-MRI before surgery were included in this retrospective
study. Tumor invasion depth (T-stage) and nodal involvement (N-stage) were evaluated using
signal increase on DW-MRI, and tumor ADC was measured. Diagnostic performance of these results
was assessed by comparing them with postsurgical histopathology based on 8th TNM classification.

Results:

Sensitivity, specificity, and accuracy of DW-MRI in T-staging were 92.1%, 75%, 89.1%
for ≤T2 vs. ≥T3; and 75%, 88.5%, 82.6% for ≤T3 vs. T4. However, sensitivity, specificity, and accuracy
of DW-MRI in N-staging were 89.3%, 88.9%, 89.1% for ≤N1 vs. ≥N2; and 73.7%, 96.3%,
86.9% for ≤N2 vs. N3, respectively. Relative preoperative ADC values correlated with pT staging
(r=-0.397, p=0.006). There was also a statistically significant difference of relative ADC values between
≤T3 and T4 stages, and a cut-off of 0.64 s/mm2 could differentiate these stages with an odds
ratio of 7.714 (95% confidence interval, 1.479-40.243). The area under the receiver operating characteristic
curve for differentiating ≤T3 and T4 stages was 0.725.

Conclusion:

DW-MRI may contribute to the clinical staging of non-metastatic GC. In particular,
relative ADC of DW-MRI can distinguish T4 gastric cancer from less advanced T-stages.

Background:

Sand is one of the efficient sources of silicon. We get quite easily the
plethora of sand from the river side, Bangladesh. Utilization of the superfluous sand can be assisted to
enhance our economy.

Methods:

In this work, silicon is extracted from sand by metal–thermite reduction process and the sample of sand is collected from padma river Rajshahi, Bangladesh. The process is environmentally benign and low cost. The reduction of the sand was performed with Mg powder, and purification was done by leaching out with HCl and HF. We have studied the structural properties, chemical nature and physical morphology.

Results and Conclusion:

X-ray Diffraction (XRD) confirmed that the presence of elemental Si in the samples produced by Mg-thermite reduction process and the particle size was found 25.72±1.3 nm in an average. Surface morphology has been studied using Scanning Electron Microscopy (SEM) and the particle size seemed around 30 to 40 nm which was comparable to the obtained particle size from XRD. Fourier transform infrared spectroscopy (FTIR) showed the presence of Si-Si bonding in the investigating materials. The chemical nature of the sand has been studied by X-ray Fluorescence (XRF) analysis. Silicon content of sand was found about maximum 80%.

Las ecuaciones alométricas son una herramienta importante para la estimación precisa de la biomasa aérea de los árboles y de sus componentes. En este documento se presentan ecuaciones de aditividad para estimar la distribución de la biomasa aérea total en árboles de Pinus cembroides Zucc. En octubre de 2017, un total de 21 árboles de distintas clases diamétricas (5 cm a 40 cm) fueron derribados y seccionados en tres componentes estructurales: fuste, ramas y ramillas con hojas, para obtener su biomasa. Se formularon dos sistemas de ecuaciones no lineales, en el que la aditividad se garantizó al establecer a la biomasa aérea total como la suma de las estimaciones de la biomasa de cada componente del árbol. Los sistemas de ecuaciones fueron ajustados simultáneamente con el Método Generalizado de Momentos (GMM, por sus siglas en inglés). El sistema que integró al diámetro normal y la altura total del árbol como variables predictoras explicó más del 92% de la variación observada en los datos de biomasa de los componentes y 98% de variabilidad de la biomasa aérea total. La proporción promedio de biomasa en el fuste, ramas y ramillas con hojas comprendió 43.2%, 41.2% y 15.5% de la biomasa aérea total del árbol, respectivamente. Las ecuaciones generadas en este estudio contribuirán a mejorar la precisión en la estimación de la biomasa e inventarios de carbono en los bosques de P. cembroides.

This study was aimed at minimizing musculoskeletal disorder (MSDs) in heavers on traditional markets by completing facilities and improving lifting techniques that are in accordance with ergonomic aspects. This research was conducted in traditional markets with heaver objects which are often carried out in the process of moving goods. This study used biomechanics and physiology methods to be able to analyze body posture so that it can prevent spinal damage. The data were then analyzed using Maximum Permissible Limit (MPL), which previously carried out data collection on the size of the body posture. The analysis of the results was done to determine the value of the compression force (FC). FC values are the basis for comparison with Action Limit (AL). The results show that FC values = 10,018,078N, FC> MPL. Importantly, the position of the heavers’ posture is at a dangerous level. Proposed improvements using a tool and after being developed again will result in changes in FC values to 3370.94, FC <AL means the position of the body in a safe condition. The results of this study are expected to provide an assessment that helps prevent spinal damage.MANUAL MATERIAL HANDLING PADA PROSES PENGANGKATAN KARUNG MENGGUNAKAN PENDEKATAN BIOMEKANIKA DAN FISIOLOGI Penelitian ini bertujuan untuk meminimumkan keluhan Musculoskeletal disorder (MSDs) pada pekerja kuli panggul di pasar tradisional dengan merancang fasilitas dan memperbaiki teknik memindahkan barang yang sesuai dengan aspek ergonomis.

Published: February 2020

BACKGROUND

Gamification has remarkable potential in the learning space. The process of creating a gamified system and its influence on human behavior reflect the interaction between educators and machines.

OBJECTIVE

The purpose of this pilot study was to present Ethoshunt as a gamification-based mobile app that can be used in teaching and learning ethics.

METHODS

This study involved a mixed-methods research design. The researchers surveyed 39 undergraduate students who were introduced to Ethoshunt in order to examine the relationships between mobile app usability and positive emotions, ethical competency, and user experience. Affinity diagramming was used as a tool to organize the opinions and experiences of participants using featured gamification elements.

RESULTS

Game dynamics and game mechanics explained the functionality of Ethoshunt. In addition, the learning flow through Ethoshunt was discussed. Overall, the findings were positive, and mobile app usability had the strongest relationship with positive emotions (r=0.744, P<.001), followed by ethical competency (r=0.686, P<.001) and user experience (r=0.614, P<.001).

CONCLUSIONS

Positive emotions could be perceived as an important dimension in the development and usability of Ethoshunt. The researchers suggest that the gamification-based mobile app advocated in this study may provide ideas for ethics educators who wish to develop a technology-mediated learning environment.
