Learning in multicultural virtual teams: university's role in training globally competent graduates

Economic globalization and intensive information exchange has shifted former ideas of borders between countries and continents, having involved people in more extensive international interaction as well as oriented them towards increased personal and business relationships with representatives of other cultures. In this respect current and future students are more likely to become employed abroad or by companies that operate in the global environment. The internalization of the labor market is largely contributed to by expanding development of information and communication technology: virtual work is becoming as common as face-to-face work. Within the given context university graduates are challenged to 44 demonstrate socalled global competences which address one’s ability to work successfully with people from other cultures. This competence is considered an increasingly important skill set for upcoming graduates. This paper briefly discusses the meaning and dimensions of the concept and research into pedagogical approaches to developing students’ global competence via university’s virtual learning environment. The paper also highlights multicultural virtual teamwork as a necessary condition for developing such a competence

Neurodevelopmental Outcomes at 2 and 3.5 Years for Very Preterm Babies Enrolled in a Randomized Trial of Milking the Umbilical Cord versus Delayed Cord Clamping

Background: Guidelines published by the International Liaison Committee for Resuscitation and by the World Health Organization recommend delaying cord clamping at birth as part of routine care for infants. Objective: To study the use of milking of the cord 4 times as an alternative to enhance the redistribution of placental blood into the baby. Methods: This is a prospective cohort study of neurodevelopmental assessment by the Bayley III method of very preterm infants who had participated in a trial of delayed cord clamping versus cord milking at birth that was conducted in a neonatal tertiary care hospital. The primary outcomes were differences in cognitive, motor and language development at 2 and 3.5 years. Two-tailed analyses were performed with the χ2 test, Fisher's exact test, t test, Mann-Whitney U test and ANCOVA. Results: Out of the 58 infants enrolled in the original study, 39 infants (67%) were assessed at 2 years and 29 (50%) at 3.5 years of age. Neurodevelopmental outcomes at 2 and 3.5 years did not significantly differ between the two groups for the three Bayley III composite scores. At 3.5 years there was a trend towards higher scores for girls in the language composite scores (girls: mean = 121.6, SD = 15.22; boys: mean = 101.07, SD = 19.84) and on the motor scale (girls: mean = 124.60, SD = 18.15; boys: mean = 97.86, SD = 17.23). Conclusions: In this small number of participants followed up at 2 and 3.5 years of age, milking of the cord 4 times did not have any long-term adverse effect on neurodevelopmental outcome, suggesting that cord milking could be used as an alternative to delayed cord clamping

Recurrent pregnancy loss is associated with a pro-senescent decidual response during the peri-implantation window

During the implantation window, the endometrium becomes poised to transition to a pregnant state, a process driven by differentiation of stromal cells into decidual cells (DC). Perturbations in this process, termed decidualization, leads to breakdown of the feto-maternal interface and miscarriage, but the underlying mechanisms are poorly understood. Here, we reconstructed the decidual pathway at single-cell level in vitro and demonstrate that stromal cells first mount an acute stress response before emerging as DC or senescent DC (snDC). In the absence of immune cell-mediated clearance of snDC, secondary senescence transforms DC into progesterone-resistant cells that abundantly express extracellular matrix remodelling factors. Additional single-cell analysis of midluteal endometrium identified DIO2 and SCARA5 as marker genes of a diverging decidual response in vivo. Finally, we report a conspicuous link between a pro-senescent decidual response in peri-implantation endometrium and recurrent pregnancy loss, suggesting that pre-pregnancy screening and intervention may reduce the burden of miscarriage

Oral rivaroxaban versus standard therapy for the treatment of symptomatic venous thromboembolism : a pooled analysis of the EINSTEIN-DVT and PE randomized studies

Background: Standard treatment for venous thromboembolism (VTE) consists of a heparin combined with vitamin K antagonists. Direct oral anticoagulants have been investigated for acute and extended treatment of symptomatic VTE; their use could avoid parenteral treatment and/or laboratory monitoring of anticoagulant effects. Methods: A prespecified pooled analysis of the EINSTEIN-DVT and EINSTEIN-PE studies compared the efficacy and safety of rivaroxaban (15 mg twice-daily for 21 days, followed by 20 mg once-daily) with standard-therapy (enoxaparin 1.0 mg/kg twice-daily and warfarin or acenocoumarol). Patients were treated for 3, 6, or 12 months and followed for suspected recurrent VTE and bleeding. The prespecified noninferiority margin was 1.75. Results: 8282 patients were enrolled. 4151 received rivaroxaban and 4131 received standard-therapy. The primary efficacy outcome occurred in 86 rivaroxaban-treated patients (2.1%) compared with 95 (2.3%) standard-therapy-treated patients (hazard ratio, 0.89; 95% confidence interval [CI], 0.66-1.19; pnoninferiority<0.001). Major bleeding was observed in 40 (1.0%) and 72 (1.7%) patients in the rivaroxaban and standard-therapy groups, respectively (hazard ratio, 0.54; 95% CI, 0.37-0.79; p=0.002). In key subgroups, including fragile patients, cancer patients, patients presenting with large clots and those with a history of recurrent VTE, the efficacy and safety of rivaroxaban was similar compared with standard-therapy. Conclusion: The single-drug approach with rivaroxaban resulted in similar efficacy to standard-therapy and was associated with a significantly lower rate of major bleeding. Efficacy and safety results were consistent among key patient subgroups

Progesterone-dependent induction of phospholipase C-related catalytically inactive protein 1 (PRIP-1) in decidualizing human endometrial stromal cells

Decidualization denotes the transformation of endometrial stromal cells into specialized decidual cells. In pregnancy, decidual cells form a protective matrix around the implanting embryo, enabling coordinated trophoblast invasion and formation of a functional placenta. Continuous progesterone (P4) signaling renders decidual cells resistant to various environmental stressors, whereas withdrawal inevitably triggers tissue breakdown and menstruation or miscarriage. Here, we show that PLCL1, coding phospholipase C (PLC)-related catalytically inactive protein 1 (PRIP-1), is highly induced in response to P4 signaling in decidualizing human endometrial stromal cells (HESCs). Knockdown experiments in undifferentiated HESCs revealed that PRIP-1 maintains basal phosphoinositide 3-kinase/Protein kinase B activity, which in turn prevents illicit nuclear translocation of the transcription factor forkhead box protein O1 and induction of the apoptotic activator BIM. By contrast, loss of this scaffold protein did not compromise survival of decidual cells. PRIP-1 knockdown did also not interfere with the responsiveness of HESCs to deciduogenic cues, although the overall expression of differentiation markers, such as PRL, IGFBP1, and WNT4, was blunted. Finally, we show that PRIP-1 in decidual cells uncouples PLC activation from intracellular Ca2+ release by attenuating inositol 1,4,5-trisphosphate signaling. In summary, PRIP-1 is a multifaceted P4-inducible scaffold protein that gates the activity of major signal transduction pathways in the endometrium. It prevents apoptosis of proliferating stromal cells and contributes to the relative autonomy of decidual cells by silencing PLC signaling downstream of Gq protein-coupled receptors
