Authors: Lv Cai , Huang Yuan , Lei Qingqing , Liu Zhenxiang , Shen Shixing , Si Wenxia 
Published: October 2020

Abstract
Background
The metastasis-associated gene 1 (MTA1) has been extensively reported as a crucial oncogene, and its abnormal expression has been associated with the progression of numerous cancers. However, the role of MTA1 in renal cell carcinoma (RCC) progression and metastasis remains unclear. Herein, we investigated the expression of MTA1 and its role in RCC.

Methods
109 matched clear cell RCCs (ccRCCs) and corresponding normal tissue samples were analyzed via immunohistochemistry to test the expression of MTA1. Human A498 cell lines were transfected with pcDNA3.1-Flag (control) or Flag-MTA1 to overexpress MTA1 or with specific interfering RNA (si-MTA1) or specific interfering negative control to knockdown MTA1 expression. Transfected cells were used in wound healing and transwell invasion assay. Quantitative real time polymerase chain reaction was used to assess the effect of MTA1 on MMP2/MMP9 and E-cadherin gene expression. Western blot was used to qualify the phosphorylation of p65.

Results
Herein, we found a significantly increased expression of MTA1 in 109 ccRCCs, compared to the corresponding normal tissue. In addition, the overexpression of MTA1 in A498 cells facilitated cell migration and invasion, while the down-regulation of MTA1 expression using specific interfering RNA sequences could decrease cell migration and invasion. Furthermore, we showed that MTA1 is up-regulated in ccRCCs, which contributes to the migration and invasion of human kidney cancer cells by mediating the expression of MMP2 and MMP9 through the NF-κB signaling pathway. Similarly, we found that MTA1 could regulate E-cadherin expression in RCCs.

Conclusions
MTA1 is overexpressed in RCC and is involved in the progression of RCC through NF-κB.

Published: October 2020

AbstractBackgroundLandscape genetics is an interdisciplinary field that combines tools and techniques from population genetics with the spatially explicit principles from landscape ecology. Spatial variation in genotypes is used to test hypotheses about how landscape pattern affects dispersal in a wide range of taxa. Lichens, symbiotic associations between mycobionts and photobionts, are an entity for which little is known about their dispersal mechanism. Our objective was to infer the dispersal mechanism in the semi-aquatic lichenDermatocarpon luridumusing spatial models and the spatial variation of the photobiont,Diplosphaera chodatii. We sequenced the ITS rDNA and the β-actin gene regions of the photobiont and mapped the haplotype spatial distribution in Payuk Lake. We subdivided Payuk Lake into subpopulations and applied four spatial models based on the topography and hydrology to infer the dispersal mechanism.ResultsGenetic variation corresponded with the topography of the lake and the net flow of water through the waterbody. A lack of isolation-by-distance suggests high gene flow or dispersal within the lake. We infer the dispersal mechanism inD. luridumcould either be by wind and/or water based on the haplotype spatial distribution of its photobiont using the ITS rDNA and β-actin markers.ConclusionsWe inferred that the dispersal mechanism could be either wind and/or water dispersed due to the conflicting interpretations of our landscape hypotheses. This is the first study to use spatial modelling to infer dispersal in semi-aquatic lichens. The results of this study may help to understand lichen dispersal within aquatic landscapes, which can have implications in the conservation of rare or threatened lichens.

Published: October 2020

Abstract
Background
Most terminally ill cancer patients prefer to die at home, but a majority die in institutional settings. Research questions about this discrepancy have not been fully answered. This study applies artificial intelligence and machine learning techniques to explore the complex network of factors and the cause-effect relationships affecting the place of death, with the ultimate aim of developing policies favouring home-based end-of-life care.

Methods
A data mining algorithm and a causal probabilistic model for data analysis were developed with information derived from expert knowledge that was merged with data from 116 deceased cancer patients in southern Switzerland. This data set was obtained via a retrospective clinical chart review.

Results
Dependencies of disease and treatment-related decisions demonstrate an influence on the place of death of 13%. Anticancer treatment in advanced disease prevents or delays communication about the end of life between oncologists, patients and families. Unknown preferences for the place of death represent a great barrier to a home death. A further barrier is the limited availability of family caregivers for terminal home care. The family’s preference for the last place of care has a high impact on the place of death of 51%, while the influence of the patient’s preference is low, at 14%. Approximately one-third of family systems can be empowered by health care professionals to provide home care through open end-of-life communication and good symptom management. Such intervention has an influence on the place of death of 17%. If families express a convincing preference for home care, the involvement of a specialist palliative home care service can increase the probability of home deaths by 24%.

Conclusion
Concerning death at home, open communication about death and dying is essential. Furthermore, for the patient preference for home care to be respected, the family’s decision for the last place of care seems to be key. The early initiation of family-centred palliative care and the provision of specialist palliative home care for patients who wish to die at home are suggested.

Abstract
Background
The aim of this study was to optimize a Question Prompt List which is designed to improve communication about the heart failure trajectory among patients, family members, and health care professionals.

Methods
Data were collected in a two-round Delphi survey and a cross-sectional survey, including patients with heart failure, their family members, and health care professionals working in heart failure care in Sweden and the Netherlands. Acceptability for and demand of the Question Prompt List were assessed.

Results
A total of 96 patients, 63 family members and 26 health care professionals participated in the study. Regarding acceptability, most of the original questions were found to be relevant by the participants for inclusion in the Question Prompt List but some cultural differences exist, which resulted in two versions of the list: a Swedish version including 33 questions and a Dutch version including 38 questions. Concerning demand, participants reported that they were interested in discussing the questions in the revised Question Prompt List with a physician or a nurse. Few patients and family members reported that they were worried by the questions in the Question Prompt List and hence did not want to discuss the questions.

Conclusions
This Question Prompt List has successfully been adapted into a Swedish version and a Dutch version and includes questions about the HF trajectory which patients, their families, and health care professionals perceived to be relevant for discussion in clinical practice. Overall, patients and family members were not worried about the content in the Question Prompt List and if used in accordance with patients’ and family members’ preferences, the Question Prompt List can help to improve communication about the heart failure trajectory.
The social paradoxes of commercial surrogacy in developing countries: India before the new law of 2018
Authors: Rozée Virginie , Unisa Sayeed , de La Rochebrochard Elise 
Published: October 2020

AbstractBackgroundCommercial surrogacy is a highly controversial issue that leads to heated debates in the feminist literature, especially when surrogacy takes place in developing countries and when it is performed by local women for wealthy international individuals. The objective of this article is to confront common assumptions with the narratives and experiences described by Indian surrogates themselves.MethodsThis qualitative study included 33 surrogates interviewed in India (Mumbai, Chennai and New Delhi) who were at different stages of the surrogacy process. They were recruited through five clinics and agencies. This 2-year field study was conducted before the 2018 surrogacy law.ResultsSurrogates met the criteria fixed by the national guidelines in terms of age and marital and family situation. The commitment to surrogacy had generally been decided with the husband. Its aim was above all to improve the socioeconomic condition of the family. Women described surrogacy as offering better conditions than their previous paid activity. They had clear views on the child and their work. However, they declared that they faced difficulties and social condemnation as surrogacy is associated with extra-marital relationships. They also described a medical process in which they had no autonomy although they did not express complaints. Overall, surrogates did not portray themselves as vulnerable women and victims, but rather as mothers and spouses taking control of their destiny.ConclusionsThe reality of surrogacy in India embraces antagonistic features that we analyze in this paper as “paradoxes”. First, while women have become surrogates in response to gender constraints as mothers and wives, yet in so doing they have gone against gender norms. Secondly, while surrogacy was socially perceived as dirty work undertaken in order to survive, surrogates used surrogacy as a means to upward mobility for themselves and their children. Finally, while surrogacy was organized to counteract accusations of exploitation, surrogates were under constant domination by the medical system and had no decision-making power in the surrogacy process. This echoes their daily life as women. Although the Indian legal framework has changed, surrogacy still challenges gender norms, particularly in other developing countries where the practice is emerging.

AbstractBackgroundEmergency room reports pose specific challenges to natural language processing techniques. In this setting, violence episodes on women, elderly and children are often under-reported. Categorizing textual descriptions as containing violence-related injuries (V)vs. non-violence-related injuries (NV) is thus a relevant task to the ends of devising alerting mechanisms to track (and prevent) violence episodes.MethodsWe presentViDeS(so dubbed afterViolence Detection System), a system to detect episodes of violence from narrative texts in emergency room reports. It employs a deep neural network for categorizing textual ER reports data, and complements such output by making explicit which elements corroborate the interpretation of the record as reporting about violence-related injuries. To these ends we designed a novel hybrid technique for filling semantic frames that employs distributed representations of terms herein, along with syntactic and semantic information. The system has been validated on real data annotated with two sorts of information: about the presence vs. absence of violence-related injuries, and about some semantic roles that can be interpreted as major cues for violent episodes, such as the agent that committed violence, the victim, the body district involved, etc.. The employed dataset contains over 150K records annotated with class (V,NV) information, and 200 records with finer-grained information on the aforementioned semantic roles.ResultsWe used data coming from an Italian branch of the EU-Injury Database (EU-IDB) project, compiled by hospital staff. Categorization figures approach full precision and recall for negative cases and.97 precision and.94 recall on positive cases. As regards as the recognition of semantic roles, we recorded an accuracy varying from.28 to.90 according to the semantic roles involved. Moreover, the system allowed unveiling annotation errors committed by hospital staff.ConclusionsExplaining systems’ results, so to make their output more comprehensible and convincing, is today necessary for AI systems. Our proposal is to combine distributed and symbolic (frame-like) representations as a possible answer to such pressing request for interpretability. Although presently focused on the medical domain, the proposed methodology is general and, in principle, it can be extended to further application areas and categorization tasks.
Haemagglutinin displayed on the surface of Lactococcus lactis confers broad cross-clade protection against different H5N1 viruses in chickens
Authors: Lei Han , Gao Tong , Cen Qianhong , Peng Xiaojue 
Published: October 2020

Abstract
Background
The highly pathogenic avian influenza (HPAI) H5N1 virus poses a potential threat to the poultry industry. The currently available avian influenza H5N1 vaccines for poultry are clade-specific. Therefore, an effective vaccine for preventing and controlling H5N1 viruses belonging to different clades needs to be developed.

Results
Recombinant L. lactis/pNZ8148-Spax-HA was generated, and the influenza virus haemagglutinin (HA) protein of A/Vietnam/1203/2004 (H5N1) was displayed on the surface of Lactococcus lactis (L. lactis). Spax was used as an anchor protein. Chickens vaccinated orally with unadjuvanted L. lactis/pNZ8148-Spax-HA could produce significant humoral and mucosal responses and neutralizing activities against H5N1 viruses belonging to different clades. Importantly, unadjuvanted L. lactis/pNZ8148-Spax-HA conferred cross-clade protection against lethal challenge with different H5N1 viruses in the chicken model.

Conclusion
This study provides insights into the cross-clade protection conferred by unadjuvanted L. lactis/pNZ8148-Spax-HA, and the results might help the establishment of a promising platform for the development of a safe and effective H5N1 cross-clade vaccine for poultry.

Authors: Müller Marianne , Haenni Hoti Andrea 
Published: October 2020

AbstractAimTo test the psychometric properties of the KIDSCREEN-10.BackgroundIt is important to assess mental health and well-being in children for an early detection of psychological problems or hidden morbidities. There is limited knowledge about the psychometric quality of the reduced version of the KIDSCREEN questionnaire with only 10 items.MethodsAnalysis of psychometric properties was done by fitting Rasch models and graphical loglinear Rasch models to data collected in a study on acculturation of primary school children and their teachers in 2017.ResultsThe data did not fit a Rasch model but did fit a graphical loglinear Rasch model. There was local dependence for four item pairs and differential item functioning for gender and citizenship.ConclusionsThe KIDSCREEN-10 provides essentially valid measurements of health-related quality of life in children if local dependency and dif ferential item functioning are taken into account. Reliability and targeting were less than satisfactory, especially for certain subgroups but reliability was adequate for most groups.

Abstract
Background
Aberrant activation of the phosphatidylinositol 3-kinase (PI3K) pathway is common in many malignancies, including head and neck squamous cell carcinoma (HNSCC). Despite pre-clinical and clinical studies, outcomes from targeting the PI3K pathway have been underwhelming and the development of drug resistance poses a significant barrier to patient treatment. In the present study, we examined mechanisms of acquired resistance to the PI3Kα inhibitor alpelisib (formerly BYL719) in HNSCC cell lines and patient-derived xenografts (PDXs).

Methods
Five unique PDX mouse models and three HNSCC cell lines were used. All cell lines and xenografts underwent genomic characterization prior to study. Serial drug treatment was conducted in vitro and in vivo to develop multiple, clinically-significant models of resistance to alpelisib. We then used reverse phase protein arrays (RPPAs) to profile the expression of proteins in parental and drug-resistant models. Top hits were validated by immunoblotting and immunohistochemistry. Flow cytometric analysis and RNA interference studies were then used to interrogate the molecular mechanisms underlying acquired drug resistance.

Results
Prolonged treatment with alpelisib led to upregulation of TAM family receptor tyrosine kinases TYRO3 and AXL. Importantly, a significant shift in expression of both TYRO3 and AXL to the cell surface was detected in drug-resistant cells. Targeted knockdown of TYRO3 and AXL effectively re-sensitized resistant cells to PI3Kα inhibition. In vivo, resistance to alpelisib emerged following 20–35 days of treatment in all five PDX models. Elevated TYRO3 expression was detected in drug-resistant PDX tissues. Downstream of TYRO3 and AXL, we identified activation of intracellular MAPK signalling. Inhibition of MAPK signalling also re-sensitized drug-resistant cells to alpelisib.

Conclusions
We have identified TYRO3 and AXL receptors to be key mediators of resistance to alpelisib, both in vitro and in vivo. Our findings suggest that pan-TAM inhibition is a promising avenue for combinatorial or second-line therapy alongside PI3Kα inhibition. These findings advance our understanding of the role TAM receptors play in modulating the response of HNSCC to PI3Kα inhibition and suggest a means to prevent, or at least delay, resistance to PI3Kα inhibition in order to improve outcomes for HNSCC patients.

Abstract
Introduction
Autosomal recessive polycystic kidney disease (ARPKD; MIM#263200) is one of the most frequent pediatric renal cystic diseases, with an incidence of 1:20,000. It is caused by mutations of the PKHD1 gene, on chromosome 6p12. The clinical spectrum is highly variable, ranging from late-onset milder forms to severe perinatal manifestations. The management of newborns with severe pulmonary insufficiency is challenging, and causes of early death are sepsis or respiratory failure. In cases of massive renal enlargement, early bilateral nephrectomy and peritoneal dialysis may reduce infant mortality. However, there is no conclusive data on the role of surgery, and decision-making is driven by patient’s clinical condition and expertise of the center.

Patient presentation
We hereby describe a preterm female newborn with perinatal, rapid and bilateral, abnormal growth of both kidneys, respiratory failure and initial signs of liver disease. She was subsequently confirmed to be affected by a rare and severe homozygous mutation of the PKHD1 gene, inherited from both her consanguineous parents. Our patient died 78 days after birth, due to a fungal sepsis which worsened her respiratory insufficiency.

Conclusions
This patient report shows some of the clinical and ethical issues of neonatal ARPKD, and the need of multidisciplinary approach and good communication with the family. Target next generation sequencing (NGS) techniques may guide and support clinicians, as well as guarantee to these patients the most appropriate clinical management, avoiding unnecessary and/or disproportionate treatments.

Abstract
Background
Clinical frailty among older adults admitted to intensive care has been proposed as an important determinant of patient outcomes. Among this group of patients, an acute episode of delirium is also common, but its relationship to frailty and increased risk of mortality has not been extensively explored. Therefore, the aim of this study was to explore the relationship between clinical frailty, delirium and hospital mortality of older adults admitted to intensive care.

Methods
This study is part of a Delirium in Intensive Care (Deli) Study. During the initial 6-month baseline period, clinical frailty status on admission to intensive care, among adults aged 50 years or more; acute episodes of delirium; and the outcomes of intensive care and hospital stay were explored.

Results
During the 6-month baseline period, 997 patients, aged 50 years or more, were included in this study. The average age was 71 years (IQR, 63–79); 55% were male (n = 537). Among these patients, 39.2% (95% CI 36.1–42.3%, n = 396) had a Clinical Frailty Score (CFS) of 5 or more, and 13.0% (n = 127) had at least one acute episode of delirium. Frail patients were at greater risk of an episode of delirium (17% versus 10%, adjusted rate ratio (adjRR) = 1.71, 95% confidence interval (CI) 1.20–2.43, p = 0.003), had a longer hospital stay (2.6 days, 95% CI 1–7 days, p = 0.009) and had a higher risk of hospital mortality (19% versus 7%, adjRR = 2.54, 95% CI 1.72–3.75, p < 0.001), when compared to non-frail patients. Patients who were frail and experienced an acute episode of delirium in the intensive care had a 35% rate of hospital mortality versus 10% among non-frail patients who also experienced delirium in the ICU.

Conclusion
Frailty and delirium significantly increase the risk of hospital mortality. Therefore, it is important to identify patients who are frail and institute measures to reduce the risk of adverse events in the ICU such as delirium and, importantly, to discuss these issues in an open and empathetic way with the patient and their families.
