LINC00261 Is an Epigenetically Regulated Tumor Suppressor Essential for Activation of the DNA Damage Response.

Lung cancer is the leading cause of cancer-related death in the United States. Long noncoding RNAs (lncRNA) are a class of regulatory molecules whose role in lung carcinogenesis is poorly understood. In this study, we profiled lncRNA expression in lung adenocarcinoma (LUAD) cell lines, compared their expression with that of purified alveolar epithelial type II cells (the purported cell of origin for LUAD), cross-referenced these with lncRNAs altered in the primary human tumors, and interrogated for lncRNAs whose expression correlated with patient survival. We identified LINC00261, a lncRNA with unknown function in LUAD, adjacent to the pioneering transcription factor FOXA2. Loss of LINC00261 was observed in multiple tumor types, including liver, breast, and gastric cancer. Reintroduction of LINC00261 into human LUAD cell lines inhibited cell migration and slowed proliferation by inducing G2-M cell-cycle arrest, while upregulating DNA damage pathway genes and inducing phosphorylation-mediated activation of components of the DNA damage pathway. FOXA2 was able to induce LINC00261 expression, and the entire locus underwent hypermethylation in LUAD, leading to loss of expression. We have thus identified an epigenetically deregulated lncRNA, whose loss of expression in LUAD promotes the malignant phenotype and blocks activation of the DNA damage machinery, predisposing lung cells to cancer development. SIGNIFICANCE: These findings identify LINC00261 as a tumor suppressor that blocks cellular proliferation by activating the DNA damage response and suggest that epigenetic therapy to inhibit DNA methylation may enhance treatment of LUAD.

Machine and deep learning for workflow recognition during surgery

Abstract Recent years have seen tremendous progress in artificial intelligence (AI), such as with the automatic and real-time recognition of objects and activities in videos in the field of computer vision. Due to its increasing digitalization, the operating room (OR) promises to directly benefit from this progress in the form of new assistance tools that can enhance the abilities and performance of surgical teams. Key for such tools is the recognition of the surgical workflow, because efficient assistance by an AI system requires this system to be aware of the surgical context, namely of all activities taking place inside the operating room. We present here how several recent techniques relying on machine and deep learning can be used to analyze the activities taking place during surgery, using videos captured from either endoscopic or ceiling-mounted cameras. We also present two potential clinical applications that we are developing at the University of Strasbourg with our clinical partners.
Effect of Axon Misdirection on Recovery of Electromyographic Activity and Kinematics after Peripheral Nerve Injury

In this study, patterns of activity in the soleus (Sol) and tibialis anterior (TA) muscles and hindlimb kinematics were evaluated during slope walking in rats after transection and surgical repair either of the entire sciatic nerve (Sci group) or of its two branches separately, the tibial and common fibular nerves (T/CF group). With the latter method, axons from the tibial and common fibular nerves could not reinnervate targets of the other nerve branch after injury, reducing the opportunity for misdirection. Activity in the TA shifted from the swing phase in intact rats to nearly the entire step cycle in both injured groups. Since these changes occur without misdirection of regenerating axons, they are interpreted as centrally generated. Sol activity was changed from reciprocal to that of TA in intact rats to coactivate with TA, but only in the Sci group rats. In the T/CF group rats, Sol activity was not altered from that observed in intact rats. Despite effects of injury that limited foot movements, hindlimb kinematics were conserved during downslope walking in both injury groups and during level walking in the T/CF group. During level walking in the Sci group and during upslope walking in both groups of injured rats, the ability to compensate for the effects of the nerve injury was less effective and resulted in longer limb lengths held at more acute angles throughout the step cycle. Changes in limb movements occur irrespective of axon misdirection and reflect compensatory changes in the outputs of the neural circuits that drive locomotion.
Telling a ‘good or white lie’: The views of people living with dementia and their carers

Objective A common symptom of cognitive decline in people living with dementia, or people with memory problems, the cause of which has not yet been diagnosed, is the person repeatedly asking for loved ones who are deceased or making statements that are incorrect. Carers are then faced with a dilemma, do they avoid and distract or ‘correct’ the person and tell the ‘truth’, or tell a lie. This paper explores the concept of lying from the perspective of people living with dementia in the community and their informal/unpaid carers. Methods A descriptive qualitative study utilising focus groups to collect the data was conducted. Three focus group’s with a purposive sample of people with memory problems (n = 14) and three focus group’s with informal/unpaid carers (n = 18) were undertaken. Qualitative content analysis was used to analyse the data. Results All participants considered that blatant lying with the intention to deceive and do harm is not acceptable. However, telling a ‘good lie’ or ‘white lie’ to alleviate distress was in certain circumstances considered acceptable. The intention behind the ‘lie’ in their view had to be to do good, and the informal/unpaid carer telling the lie had to really ‘know the person’ and be cognisant of family preferences. Some informal/unpaid carers acknowledged that it may be acceptable for health care professionals to tell a ‘good lie’ or ‘small lie’ in certain circumstances. However, health professionals need to ‘know the person’ and need to consider informal/family caregivers’ wishes. Conclusion Lying was only considered acceptable in the context of knowing the person and when done with the intention not to harm or deceive, undertaken with empathy, and only for the purpose of mitigating the person living with dementia’s distress.
The association between the Nutrition‐Related index and morbidity following head and neck microsurgery

Despite consensus that preoperative nutritional assessment is of importance in the head and neck surgical oncology population, it remains unclear how exactly malnutrition is associated with perioperative morbidity especially among those undergoing microvascular surgery. We aimed to study this association to help inform preoperative risk stratification, guide the use of nutritional interventions, and ultimately help prevent malnutrition related morbidity.
Vertical stratification of bacteria and archaea in sediments of a small boreal humic lake

ABSTRACT Although sediments of small boreal humic lakes are important carbon stores and greenhouse gas sources, the composition and structuring mechanisms of their microbial communities have remained understudied. We analyzed the vertical profiles of microbial biomass indicators (PLFAs, DNA and RNA) and the bacterial and archaeal community composition (sequencing of 16S rRNA gene amplicons and qPCR of mcrA) in sediment cores collected from a typical small boreal lake. While microbial biomass decreased with sediment depth, viable microbes (RNA and PLFA) were present all through the profiles. The vertical stratification patterns of the bacterial and archaeal communities resembled those in marine sediments with well-characterized groups (e.g. Methanomicrobia, Proteobacteria, Cyanobacteria, Bacteroidetes) dominating in the surface sediment and being replaced by poorly-known groups (e.g. Bathyarchaeota, Aminicenantes and Caldiserica) in the deeper layers. The results also suggested that, similar to marine systems, the deep bacterial and archaeal communities were predominantly assembled by selective survival of taxa able to persist in the low energy conditions. Methanotrophs were rare, further corroborating the role of these methanogen-rich sediments as important methane emitters. Based on their taxonomy, the deep-dwelling groups were putatively organo-heterotrophic, organo-autotrophic and/or acetogenic and thus may contribute to changes in the lake sediment carbon storage.
Drug Therapies for Peripheral Joint Disease in Psoriatic Arthritis: A Systematic Review

In 2009, GRAPPA published their first evidence-based recommendations for the treatment of psoriasis and psoriatic arthritis (PsA). Since then, new information has been published and drugs developed. We summarize evidence for the efficacy of available treatments for peripheral joint involvement in PsA. We performed a systematic review of current literature on the efficacy of different therapies, management, and therapeutic strategies for peripheral arthritis involvement in PsA, in order to provide information for the development of the new GRAPPA treatment recommendations.
Metabolic effects of antidiabetic drugs on adipocytes and adipokine expression

Several classes of antidiabetic agents have been developed that achieve their hypoglycemic outcomes via various molecular mechanisms. Adipose tissue is a major metabolic and energy‐storing tissue and plays an important role in many metabolic pathways, including insulin signaling and insulin sensitivity. Adipose tissue monitors and regulates whole body homeostasis via production and release of potent proteins, such as adipokine and adiponectin, into the circulation. Therefore, any agent that can modulate adipocyte metabolism can, in turn, affect metabolic and glucose homeostatic pathways. Antidiabetic drugs are not only recognized primarily as hypoglycemic agents but may also alter adipose tissue itself, as well as adipocyte‐derived adipokine expression and secretion. In the current review, we present the major evidence concerning routinely used antidiabetic agents on adipocyte metabolism and adipokine expression.
Medical Doctors’ Offline Computer-Assisted Digital Education: Systematic Review by the Digital Health Education Collaboration

Background The widening gap between innovations in the medical field and the dissemination of such information to doctors may affect the quality of care. Offline computer-based digital education (OCDE) may be a potential solution to overcoming the geographical, financial, and temporal obstacles faced by doctors. Objective The objectives of this systematic review were to evaluate the effectiveness of OCDE compared with face-to-face learning, no intervention, or other types of digital learning for improving medical doctors’ knowledge, cognitive skills, and patient-related outcomes. Secondary objectives were to assess the cost-effectiveness (CE) of OCDE and any adverse effects. Methods We searched major bibliographic databases from 1990 to August 2017 to identify relevant articles and followed the Cochrane methodology for systematic reviews of intervention. Results Overall, 27 randomized controlled trials (RCTs), 1 cluster RCT (cRCT), and 1 quasi-RCT were included in this review. The total number of participants was 1690 in addition to the cRCT, which included 24 practices. Due to the heterogeneity of the participants, interventions, and outcomes, meta-analysis was not feasible, and the results were presented as narrative summary. Compared with face-to-face learning, the effect of OCDE on knowledge gain is uncertain (ratio of the means [RM] range 0.95-1.17; 8 studies, 495 participants; very low grade of evidence). From the same comparison, the effect of OCDE on cognitive skill gain is uncertain (RM range 0.1-0.9; 8 studies, 375 participants; very low grade of evidence). OCDE may have little or no effect on patients’ outcome compared with face-to-face education (2 studies, 62 participants; low grade of evidence). Compared with no intervention, OCDE may improve knowledge gain (RM range 1.36-0.98; 4 studies, 401 participants; low grade of evidence). From the same comparison, the effect of OCDE on cognitive skill gain is uncertain (RM range 1.1-1.15; 4 trials, 495 participants; very low grade of evidence). One cRCT, involving 24 practices, investigated patients’ outcome in this comparison and showed no difference between the 2 groups with low-grade evidence. Compared with text-based learning, the effect of OCDE on cognitive skills gain is uncertain (RM range 0.91-1.46; 3 trials with 4 interventions; 68 participants; very low-grade evidence). No study in this comparison investigated knowledge gain or patients’ outcomes. One study assessed the CE and showed that OCDE was cost-effective when compared with face-to-face learning if the cost is less than or equal to Can $200. No trial evaluated the adverse effect of OCDE. Conclusions The effect of OCDE compared with other methods of education on medical doctors’ knowledge and cognitive skill gain is uncertain. OCDE may improve doctors’ knowledge compared with no intervention but its effect on doctors’ cognitive skills is uncertain. OCDE may have little or no effect in improving patients’ outcome.
Growth, structural and optical characterization of wurtzite GaP nanowires

Bulk gallium phosphide (GaP) crystallizes in the zinc-blende (ZB) structure and has an indirect bandgap. However, GaP nanowires (NWs) can be synthesized in the wurtzite (WZ) phase as well. The contradictory theoretical predictions and experimental reports on the band structure of WZ GaP suggest a direct or a pseudo-direct bandgap. There are only a few reports of the growth and luminescence from WZ and ZB GaP NWs. We first present a comprehensive study of the gold-catalyzed growth of GaP NWs via metalorganic vapor phase epitaxy on various crystalline and amorphous substrates. We optimized the growth parameters like temperature, pressure and reactant flow rates to grow WZ GaP NWs with minimal taper. These wires were characterized using electron microscopy, x-ray diffraction, Raman scattering and photoluminescence spectroscopy. The luminescence studies of bare GaP NWs and GaP/AlGaP core–shell heterostructures with WZ- and ZB-phase GaP cores suggest that the WZ-phase GaP has a pseudo-direct bandgap with weak near-band-edge luminescence intensity.
Effects of hearing aid settings for electric-acoustic stimulation.

BACKGROUND Cochlear implant (CI) recipients with postoperative hearing preservation may utilize an ipsilateral bimodal listening condition known as electric-acoustic stimulation (EAS). Studies on EAS have reported significant improvements in speech perception abilities over CI-alone listening conditions. Adjustments to the hearing aid (HA) settings to match prescription targets routinely used in the programming of conventional amplification may provide additional gains in speech perception abilities. PURPOSE Investigate the difference in users' speech perception scores when listening with the recommended HA settings for EAS patients versus HA settings adjusted to match National Acoustic Laboratories' nonlinear fitting procedure version 1 (NAL-NL1) targets. RESEARCH DESIGN Prospective analysis of the influence of HA settings. STUDY SAMPLE Nine EAS recipients with greater than 12 mo of listening experience with the DUET speech processor. INTERVENTION Subjects were tested in the EAS listening condition with two different HA setting configurations. Speech perception materials included consonant-nucleus-consonant (CNC) words in quiet, AzBio sentences in 10-talker speech babble at a signal-to-noise ratio (SNR) of +10, and the Bamford-Kowal-Bench sentences in noise (BKB-SIN) test. DATA COLLECTION AND ANALYSIS The speech perception performance on each test measure was compared between the two HA configurations. RESULTS Subjects experienced a significant improvement in speech perception abilities with the HA settings adjusted to match NAL-NL1 targets over the recommended HA settings. CONCLUSIONS EAS subjects have been shown to experience improvements in speech perception abilities when listening to ipsilateral combined stimulation. This population's abilities may be underestimated with current HA settings. Tailoring the HA output to the patient's individual hearing loss offers improved outcomes on speech perception measures.
Early Paternal Support Behaviors Moderate Consonant Smoking Among Unmarried Parents.

OBJECTIVE Unmarried mothers have high rates of smoking, including during late pregnancy and after pregnancy, thus increasing their children's risk for negative health outcomes associated with maternal tobacco use. Few studies have examined whether partners' smoking exacerbates or attenuates maternal smoking risk. The current study examines how fathers' behaviors during the third trimester of pregnancy and after pregnancy influence maternal smoking across the first 9 years of a child's life. METHOD Unmarried parents (N = 2,580 pairs) from the Fragile Families and Child Wellbeing Study were measured four times. Paternal and maternal tobacco use during the third trimester was assessed via retrospective report at baseline (the time of the child's birth). Parents also reported tobacco use 1 year, 5 years, and 9 years later. Paternal supportive behaviors were self-reported at baseline. RESULTS Paternal tobacco use predicted maternal tobacco use. This association was moderated by paternal supportive behaviors as reported by fathers (b = 0.51, 95% CI [0.22, 0.81], p = .001; adjusted odds ratio = 1.67, 95% CI [1.24, 2.25]). Paternal smoking predicted maternal smoking for fathers who reported both high and low levels of supportive behaviors, but this relationship was stronger for fathers who engaged in the highest levels of support. CONCLUSIONS Unmarried fathers' smoking had a stronger relationship to maternal smoking during late pregnancy and postpartum when fathers engaged in more support behaviors. The results of this study suggest that targeting fathers' smoking cessation may help improve the effectiveness of tobacco cessation programs for at-risk unmarried mothers.
Cancer esearch cular and Cellular Pathobiology miR-1792 Cluster of MicroRNAs Confers Tumorigenicity R nhibiting Oncogene-Induced Senescence

Downlo ammalian cells, activation of oncogenes usually triggers innate tumor-suppressing defense mechanisms, ing apoptosis and senescence, which are compromised by additional mutations before cancers are develThe miR-17-92 gene cluster, a polycistron encoding six microRNAs (miRNA), is frequently overexpressed an cancers and has been shown to promote several aspects of oncogenic transformation, including evaf apoptosis. In the current study, we show a new role of miR-17-92 in inhibiting oncogenic ras-induced ence. Further dissection of the miRNA components in this cluster reveals that the miR-17/20a seed family nts for this antisenescence activity. miR-17 and miR-20a are both necessary and sufficient for conferring nce to ras-induced senescence by directly targeting p21, a key effector of senescence. By contrast, components are not essential for the ability of miR-17-92 to evade Myc-induced apoptosis. Moreover, tion of senescence by miR-17-92 or its miR-17/20a components leads to enhanced oncogenic transforn by activated ras in primary human cells. Taken together with previous reports that miR-17-92 inhibits sis by suppressing Pten via the miR-19 components, our results indicate that this miRNA cluster proapopto motes tumorigenesis by antagonizing both tumor-suppressing mechanisms, apoptosis, and senescence, through the activities of different miRNA components encoded in this cluster.

Factors affecting outcome in participation one year after stroke: A secondary analysis of a randomized controlled trial.

OBJECTIVE To explore the importance of client characteristics (age, sex, stroke severity and participation before stroke), rehabilitation context (in-patient or client's home) and approach (enhanced client-centeredness or not) on participation in every-day life after stroke. METHODS A secondary analysis of data on 237 participants from a previous randomized controlled trial evaluating an enhanced client-centred intervention after stroke. Plausible associations between client characteristics, context and rehabilitation approach, and a positive outcome regarding participation were explored. Three different outcome measures for participation were used: Stroke Impact Scale 3.0, domain participation; Frenchay Activities Index; and Occupational Gaps Questionnaire. RESULTS For all participants there was a significant association between mild stroke and a positive outcome using the Frenchay Activities Index. Among participants who had not received the enhanced client-centred approach, there was a significant association between mild stroke and a positive outcome using the Stroke Impact Scale. The context of rehabilitation, i.e. receiving home rehabilitation, was also associated with a positive outcome in the Frenchay Activities Index for the control group. CONCLUSION In order to increase participation in every-day life for people after stroke it appears to be important to use an enhanced client-centred approach, particularly when working within in-patient rehabilitation and with people with moderate or severe stroke.
Potential nephrotoxic effects produced by steroidal saponins from hydro alcoholic extract of Tribulus terrestris in STZ-induced diabetic rats

Abstract Chronic hyperglycemia leads to the development of microvascular complications like diabetic nephropathy. The present study investigated the potential effects of the hydroalcoholic extract of Tribulus terrestris, a plant of Zygophyllaceae family, on the renal complications in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by administering STZ (90 mg/kg) to the 2-days old neonates. After 6 weeks of induction, diabetic rats were treated with 50 mg/kg hydroalcoholic extract of T. terrestris for 8 weeks. The anti-hyperglycaemic nature was confirmed by reduction in blood glucose and improvement in insulin levels. Diabetic renal injury associated with decrease in total proteins and albumin levels was observed to be improved by T. terrestris extract. Glomerular filtration rate along with inflammatory and growth factors, adiponectin and erythropoietin were also improved by the treatment, though the findings were not significant. However, the beneficial antidiabetic effects of T. terrestris extract in plasma were not observed in kidney histopathology. This was confirmed by the quantitative estimation of unhydrolyzed fraction of saponins (major component: protodioscin) in plasma and kidney samples of normal and diabetic rats. Hence, it can be concluded that 8 weeks treatment with T. terrestris extract produces potential toxic effects in kidney, which are independent of its anti-diabetic action.
