Authors: Doddamani Divya , Naik Saraswathi V. , Betur Archana P. , Suriyan Sugandhan , Nadig Basappa 
Published: May 2021

Background: Nasoalveolar molding (NAM) is a presurgical orthopedic procedure, mainly focusing upon the aesthetic outcome of the treatment goal by reducing the number of reconstructive surgeries performed later for the purpose of esthetics. It was reported a very small proportion of pediatric dentists are providing presurgical intervention and the practice of NAM still side stepping among various dental practitioners. Objectives: The study was aimed to assess the knowledge and attitude among various dental specialties regarding NAM procedure in cleft patients. Materials and Methods: A questionnaire-based cross-sectional survey was carried out among 180 dental professionals (pedodontists, orthodontists, prosthodontists, oral surgeons). A total of 180 questionnaires were prepared, out of which 98 were filled through direct personal interview and 82 were circulated via Google forms. Results were analyzed using chi-square test, Mann-Whitney U test, and Kruskal-Wallis test. Results: There was statistically significant difference in the cumulative knowledge scores between specialty with P < .001; 99% of the participants think one should opt for NAM before cleft lip and palate surgery and 39% participants prefer pedodontists to carry out NAM procedure. Conclusion: Dental specialists in India have a positive attitude toward presurgical orthopedics. Majority of them agreed that there is great improvement in the aesthetic outcomes of surgeries after NAM intervention.
Is Negative Group Affective Tone Always Bad For Team Creativity? Team Trait Learning Goal Orientation as the Boundary Condition
Authors: Chi Nai-Wen , Lam Long W 
Published: May 2021

Although previous studies have found that positive group affective tone is generally good for team creativity, the reported effects of negative group affective tone (NGAT) are mixed. Drawing on the team goal orientation composition literature, we propose that team trait learning goal orientation (TTLGO; aggregated level of team members’ trait learning goal orientation) will moderate the relationship between NGAT and team creativity. Specifically, NGAT will be positively related to team creativity when TTLGO is high but becomes negative when TTLGO is low. We further theorize that team information exchange accounts for this moderating effect. Employing a multiple-source and time-lag design, we conducted two studies to test the hypotheses. In Study 1, we collected data from 270 information technology engineers working in 62 R&D teams in a software development company and examined the moderating effect of TTLGO on the NGAT-team creativity relationship. In Study 2, we replicated the findings of Study 1 and further tested the mediating role of team information exchange (i.e., Hypothesis 2) using data from 237 members of 43 diversified teams (e.g., R&D, advertising and marketing, technical services, and quality improvement). The results of these two studies support our hypotheses. Theoretical and practical implications for group affect and creativity literature are further discussed.

Objectives Changes in bowel movements (BMs) are an important clinical sign in many diseases, including chronic kidney disease (CKD), and the purpose of this study was to collect information on BMs and fecal scores in both apparently healthy and CKD cats. A secondary aim was to assess owner awareness of BM frequency. Methods Owners were asked to complete an initial online questionnaire about their cat’s health and litter box habits (including predicted BM frequency and fecal scores) and were then asked to clean the box daily for 7 days and report results (observed frequency of BMs and fecal scores) daily. Differences in BM frequency and fecal scores between apparently normal and CKD cats were compared using the Mann–Whitney test, and predicted vs observed data were compared using the Wilcoxon signed rank test. Difference in percentage of cats defecating more or less than once daily were assessed with Fisher’s exact test. Results Survey data from 124 owners of apparently healthy cats and 43 owners of CKD cats who submitted two or more days of daily observations (in addition to the initial questionnaire) were analyzed. Eighty-five percent of apparently healthy cats were observed to defecate one or more times per day and 15% defecated less than once per day. Fifty-eight percent of CKD cats defecated one or more times per day and 42% defecated less than once per day. A significantly higher percentage of CKD cats defecated less than once per day in comparison with apparently healthy cats ( P <0.0001). Observed BM frequency was significantly less in CKD cats compared with healthy cats ( P = 0.02). Observed fecal scores were not significantly different between healthy and CKD cats. Conclusions and relevance The observed BM frequency of cats with CKD was less than apparently healthy cats and represents a clinically important variation from normal.

Published: May 2021

Purpose: Inflammatory breast cancer (IBC) is a rare, aggressive and special subtype of primary breast cancer. We aimed to establish competing-risks nomograms to predict the IBC-specific death (BCSD) and other-cause-specific death (OCSD) of IBC patients. Methods: We extracted data on primary IBC patients from the SEER (Surveillance, Epidemiology, and End Results) database by applying specific inclusion and exclusion criteria. Cumulative incidence function (CIF) was used to calculate the cumulative incidence rates and Gray’s test was used to evaluate the difference between groups. Fine-Gray proportional subdistribution hazard method was applied to identify the independent predictors. We then established nomograms to predict the 1-, 3-, and 5-year cumulative incidence rates of BCSD and OCSD based on the results. The calibration curves and concordance index (C-index) were adopted to validate the nomograms. Results: We enrolled 1699 eligible IBC patients eventually. In general, the 1-, 3-, and 5-year cumulative incidence rates of BCSD were 15.3%, 41.0%, and 50.7%, respectively, while those of OCSD were 3.0%, 5.1%, and 7.4%. The following 9 variables were independent predictive factors for BCSD: race, lymph node ratio (LNR), AJCC M stage, histological grade, ER (estrogen receptor) status, PR (progesterone receptor) status, HER-2 (human epidermal growth factor-like receptor 2) status, surgery status, and radiotherapy status. Meanwhile, age, ER, PR and chemotherapy status could predict OCSD independently. These factors were integrated for the construction of the competing-risks nomograms. The results of calibration curves and C-indexes indicated the nomograms had good performance. Conclusions: Based on the SEER database, we established the first competing-risks nomograms to predict BCSD and OCSD of IBC patients. The good performance indicated that they could be incorporated in clinical practice to provide references for clinicians to make individualized treatment strategies.

Published: May 2021

Background: Current treatment for head and neck cancers (HNCs) have led to an improved survival. However, the sequelae of cancer treatment often result in trismus, or reduced mouth opening. The purpose of this report is to identify interventional studies for trismus management in HNC patients. Methods: A search of PubMed, Embase, Cumulated Index to Nursing and Allied Health Literature, and the Cochrane Library was conducted in March 2020 for randomized controlled trials (RCTs) involving interventions for trismus for head and neck cancer within 10 years. Intervention could involve the use of an exercise regime, jaw rehabilitation device, technological device, medication or massage therapy. The primary outcome was the measurement of mouth opening. Results: Eleven RCTs involving a total of 685 patients with HNC were included. Six RCTs evaluated the effectiveness of a jaw mobilization device with exercises; there was no significant benefit of an exercise regime with a jaw mobilization device either initiated before, during or after treatment compared to no exercise. Two RCTs compared 2 intervention groups that involved exercises only, with 1 study assessing the benefit of weekly supervised physical therapy with gum chewing and another evaluating the benefit of immediate (1-2 days) versus delayed (7-10 days) initiation of exercise post-surgery; there was no significant difference between groups in either study. One RCT that recruited only patients with trismus demonstrated that an exercise regime in combination with low-level laser therapy or low-intensity ultrasound had superior results in mouth opening measurements compared to exercise alone. Two RCTs compared intervention groups with and without follow-up reminders; both studies showed a significant improvement in mouth opening measurements in groups with follow-up reminders. Conclusion: This systematic review did not convey a clear consensus as to optimal intervention for trismus in HNC patients. A variety of exercise regimens and jaw rehabilitation devices appear to have comparable effectiveness. However, efforts focused on increasing adherence to a particular intervention protocol may positively impact mouth opening measures in head and neck cancer patients. Also, low-level laser therapy and low-intensity ultrasound coupled with exercise may be beneficial for patients with trismus.

Published: May 2021

The entry of the biological medicinal products (BMPs) in the clinical practice more than 10 years ago raised complex regulatory issues as well as significant pharmacoeconomic concerns, because the costs of treatment is higher than the costs of the conventional products. The “data exclusivity” of BMPs expired and biosimilar medicinal products (BSMPs) are available on the market. The market share of BSMPs is expected to increase gradually and lead to cost reductions of biological treatment. Aim: To analyze the availability, affordability and drug utilization of BSMPs containing monoclonal antibodies in Bulgaria. Materials and methods: Retrospective study of the public data from EMA, National Council on Prices and Reimbursement and National Health Insurance Fund for 2015–2019. Descriptive statistical analysis was performed. Results and Discussion: On the ЕU level, BSMPs with Marketing Authorization are Adalimumab, Infliximab, Rituximab, Bevacizumab and Trastuzumab. In the Bulgarian Positive Drug List, there are 12 BSMPs with the same INN, excluding Bevacizumab. The total cost of BMPs is 691 673 158 BGN – the share of BSMPs is 34 139 639 BGN (4.7%). The access of BSMPs in Bulgaria is still very limited. BSMPs are available with the lower price, but the reference products are the preferred treatment. The reason for this could be the lack of national standards for the switching/interchangeability of BMPs with BSMPs, and the prescribers distrust of the so-called replacement therapies and aggressive drug promotion to the healthcare professionals are also of great importance.
WEScover: selection between clinical whole exome sequencing and gene panel testing
Authors: Lee In-Hee , Lin Yufei , Alvarez William Jefferson , Hernandez-Ferrer Carles , Mandl Kenneth D. , Kong Sek Won 
Published: May 2021

Abstract
Background
Whole exome sequencing (WES) is widely adopted in clinical and research settings; however, one of the practical concerns is the potential false negatives due to incomplete breadth and depth of coverage for several exons in clinically implicated genes. In some cases, a targeted gene panel testing may be a dependable option to ascertain true negatives for genomic variants in known disease-associated genes. We developed a web-based tool to quickly gauge whether all genes of interest would be reliably covered by WES or whether targeted gene panel testing should be considered instead to minimize false negatives in candidate genes.

Results
WEScover is a novel web application that provides an intuitive user interface for discovering breadth and depth of coverage across population-scale WES datasets, searching either by phenotype, by targeted gene panel(s) or by gene(s). Moreover, the application shows metrics from the Genome Aggregation Database to provide gene-centric view on breadth of coverage.

Conclusions
WEScover allows users to efficiently query genes and phenotypes for the coverage of associated exons by WES and recommends use of panel tests for the genes with potential incomplete coverage by WES.
Impact of uORFs in mediating regulation of translation in stress conditions
Authors: Moro Simone G. , Hermans Cedric , Ruiz-Orera Jorge , Albà M. Mar 
Published: May 2021

Abstract
Background
A large fraction of genes contains upstream ORFs (uORFs) in the 5′ untranslated region (5’UTR). The translation of uORFs can inhibit the translation of the main coding sequence, for example by causing premature dissociation of the two ribosomal units or ribosome stalling. However, it is currently unknown if most uORFs are inhibitory or if this activity is restricted to specific cases. Here we interrogate ribosome profiling data from three different stress experiments in yeast to gain novel insights into this question.

Results
By comparing ribosome occupancies in different conditions and experiments we obtain strong evidence that, in comparison to primary coding sequences (CDS), which undergo translational arrest during stress, the translation of uORFs is mostly unaffected by changes in the environment. As a result, the relative abundance of uORF-encoded peptides increases during stress. In general, the changes in the translational efficiency of regions containing uORFs do not seem to affect downstream translation. The exception are uORFs found in a subset of genes that are significantly up-regulated at the level of translation during stress; these uORFs tend to be translated at lower levels in stress conditions than in optimal growth conditions, facilitating the translation of the CDS during stress. We find new examples of uORF-mediated regulation of translation, including the Gcn4 functional homologue fil1 and ubi4 genes in S. pombe.

Conclusion
We find evidence that the relative amount of uORF-encoded peptides increases during stress. The increased translation of uORFs is however uncoupled from the general CDS translational repression observed during stress. In a subset of genes that encode proteins that need to be rapidly synthesized upon stress uORFs act as translational switches.

Abstract
Background
About 90% of cancer-related deaths are due to metastasis of cancer cells, and angiogenesis is a critical step in this process. sFLT01 is a novel fusion protein and a dual-targeting agent that neutralizes both VEGF and PlGF proangiogenic activities. GRP78 dual effect in tumor growth and angiogenesis could be activated under VEGF stimulation. The current study was designed to investigate the inhibitory impact of sFLT01 protein on VEGF/GRP78 axis. To this point, sFLT01 construct was synthesized, recombinant plasmid was expressed in eukaryotic host cells, sFLT01-HisTag protein was extracted and analyzed. The functional activity of sFLT01 on VEGF-enhanced tube formation and angiogenesis of HUVEC cells were examined. Eventually, the inhibitory impact of sFLT01 on growth, invasiveness, and migration of human prostate cancer cell line, DU145, was assessed. Real-time PCR evaluated the level of GRP78 and its effect on the downstream factors; matrix metallopeptidase proteins 2&9 (MMP2&9) along with tissue inhibitor of metalloproteinase proteins1&2 (TIMP1&2) under sFLT01 stimulation.

Results
According to the data, sFLT01 protein showed modulatory impact on proliferation, invasion, and migration of DU145 cells along with the potential of HUVECs angiogenesis. Real-Time PCR analysis depicted a significant downregulation in GRP78, MMP2 and MMP9 transcripts’ levels, and a subsequent elevation of TIMP1 and TIMP2 expression under sFLT01 stimulation was detected.

Conclusion
Overall, these data indicated that the inhibitory impact of sFLT01 on cancer cells growth and invasiveness could be mediated through the modulation of VEGF/GRP78/MMP2&9 axis and activation of TIMPs.
Genomic selection and genetic gain for nut yield in an Australian macadamia breeding population

Published: May 2021

Abstract
Background
Improving yield prediction and selection efficiency is critical for tree breeding. This is vital for macadamia trees with the time from crossing to production of new cultivars being almost a quarter of a century. Genomic selection (GS) is a useful tool in plant breeding, particularly with perennial trees, contributing to an increased rate of genetic gain and reducing the length of the breeding cycle. We investigated the potential of using GS methods to increase genetic gain and accelerate selection efficiency in the Australian macadamia breeding program with comparison to traditional breeding methods. This study evaluated the prediction accuracy of GS in a macadamia breeding population of 295 full-sib progeny from 32 families (29 parents, reciprocals combined), along with a subset of parents. Historical yield data for tree ages 5 to 8 years were used in the study, along with a set of 4113 SNP markers. The traits of focus were average nut yield from tree ages 5 to 8 years and yield stability, measured as the standard deviation of yield over these 4 years. GBLUP GS models were used to obtain genomic estimated breeding values for each genotype, with a five-fold cross-validation method and two techniques: prediction across related populations and prediction across unrelated populations.

Results
Narrow-sense heritability of yield and yield stability was low (h2 = 0.30 and 0.04, respectively). Prediction accuracy for yield was 0.57 for predictions across related populations and 0.14 when predicted across unrelated populations. Accuracy of prediction of yield stability was high (r = 0.79) for predictions across related populations. Predicted genetic gain of yield using GS in related populations was 474 g/year, more than double that of traditional breeding methods (226 g/year), due to the halving of generation length from 8 to 4 years.

Conclusions
The results of this study indicate that the incorporation of GS for yield into the Australian macadamia breeding program may accelerate genetic gain due to reduction in generation length, though the cost of genotyping appears to be a constraint at present.
Reduced plasma level of basic fibroblast growth factor is associated with incomplete device endothelialization at six months following left atrial appendage closure

Published: May 2021

Abstract
Objectives
To investigate whether inflammatory and growth factors (IGFs) were associated with incomplete device endothelialization (IDE) at 6 months after successful left atrial appendage closure (LAAC).

Background
IDE after LAAC is correlated with device-related thrombus (DRT) formation and subsequent thromboembolic events. However, biomarkers for early detection of IDE remain lacking.

Methods
Plasma levels of IGFs including basic fibroblast growth factor (bFGF), platelet derived growth factor (PDGF), stromal cell derived factor (SDF)-1a, transforming growth factor (TGF)-β1, vascular growth factor receptor-1 (VEGF-R1) and von Willebrand factor (vWF) were determined using ELISA kits in 55 consecutive patients with atrial fibrillation (AF) at 6 months after LAAC with Watchman devices. The status of device endothelialization was assessed by transesophageal echocardiography and cardiac CT.

Results
IDE and complete device endothelialization(CDE)were detected in 38 and 17 patients, respectively. Among the six IGFs, only plasma level of bFGF was significantly lower in patients with IDE compared to those with CDE (303.49 ± 246.84 vs. 556.31 ± 197.84 pg/ml, p < 0.001). C-statistics of plasma bFGF for discriminating patients with IDE from those with CDE was 0.785 (95 % CI: 0.663–0.907, p < 0.001), with a cut-off value of 440.52pg/ml (sensitivity 0.765; specificity 0.789). Multivariate logistic regression model showed that lower bFGF was an independent factor for IDE (OR: 11.752, 95 % CI: 2.869–48.144, P = 0.001). bFGF improved the classification of patients (NRI: 0.677,95 % CI: 0.320–1.033, p = 0.004).

Conclusions
Reduced plasma bFGF level confers an increased risk for IDE after LAAC. Further prospective studies are warranted to examine if bFGF could serve as a biomarker for IDE post LAAC.
