Leadership Strategies for Adapting to Changes in Ontario Colleges: Tensions, Dilemmas, and Opportunities for Continuing Education Deans/Administrative Leaders

This exploratory case study explores unique leadership challenges facing Ontario college Continuing Education leaders as they navigate institutional responses to contemporary changes in the higher education landscape. Nine Ontario college deans/administrative leaders participated in semi-structured interviews that were analyzed using a modified version of constant comparative analysis. Adopting the theoretical perspectives of sensemaking and identity from an Interpretive stance, the analysis leads to the presentation of a conceptual model that represents the interpretation of these leaders’ experiences. The conceptual model that emerged from this study adopts the position that sensemaking resolves identity ambiguities and is triggered by leadership challenges. These leaders’ identities demonstrate passionate advocacy for lifelong learning; a commitment to serving their students, their communities and their teams; and a connection to provincial colleagues that counteracts a perception of local isolation. Furthermore, participants’ leadership challenges include experiences of complexity, constant change, and varying degrees of institutional marginalization. Finally, despite commonalities of identity construction and leadership challenges, there is diversity in these leaders’ approaches to their roles, as narrated in their interviews and subsequently interpreted as distinct metaphorical cameos. The study findings suggest a similarity that Continuing Education leaders may have with a “reframing” model for approaching leadership challenges in higher education. This study contributes to the field of Educational Leadership, and presents an opportunity to gain a deeper understanding of the unique challenges and opportunities that Continuing Education leaders in Ontario colleges encounter. Recommendations suggest future research that may further develop an even deeper understanding of sensemaking phenomena as applied to leadership in the higher education setting

The effect of maternal position at birth on perineal trauma: A systematic review.

yesPerineal trauma is associated with short- and long-term maternal morbidity. Research has found that maternal position at birth can influence perineal trauma. However, there is a dearth of evidence examining specific maternal positions, including waterbirth, and how these can influence incidence and degree of perineal trauma. Such evidence is important to help reduce trauma rates and improve information for women and midwives. To address this gap in reliable evidence, a systematic review was conducted. Seven studies met the inclusion criteria. Compared to land birth, waterbirth was found to cause an increase in perineal trauma. Kneeling and all-fours positions were most protective of an intact perineum. Allowing for different variables, sitting, squatting and using a birth-stool caused the greatest incidence of trauma. The findings of this review demonstrate that further research is required around perineal guarding in alternative birth positions and how parity affects trauma rates with waterbirth, so that women may be advised appropriately. It also suggests findings that midwives can use when discussing alternative birth positions with women

Contemporary midwifery practice: Art, science or both?

Current midwifery practice is regulated by the Nursing and Midwifery Council (NMC), whose primary role is to safeguard the public through setting standards for education and practice and regulating fitness to practise, conduct and performance through rules and codes (NMC, 2012; 2015a). Practice is informed by evidence-based guidelines developed and implemented by the National Institute for Health and Care Excellence based on hierarchies of evidence, with meta-analyses and systematic reviews being identified as the ‘gold standard’. This positivist epistemological approach as developed by Auguste Comte (1798–1857), with scientific evidence at the top of a knowledge hierarchy, fails to acknowledge the ‘art of midwifery’, where a constructivist paradigm of experiential, intuitive and tacit knowledge is used by reflective practitioners to provide high-quality care. As midwifery pre-registration education is now degree-level, is the essence of midwifery practice being ‘with woman’ providing holistic care under threat, as the drive for a systematic and analytical approach to decision-making gathers momentum

Quality of Care Provided in Two Scottish Rural Community Maternity Units: a retrospective case review.

Background: Women in Scotland with uncomplicated pregnancies are encouraged by professional bodies and national guidelines to access community based models of midwife-led care for their labour and birth. The evidence base for these guidelines relates to comparisons of predominantly urban birth settings in England. There appears to be little evidence available about the quality of the care during the antenatal, birth and post birth periods available for women within the Scottish Community Maternity Unit (CMU) model. The research aim was to explore the safety and effectiveness of the maternity services provided at two rural Community Maternity Units in Scotland, both 40 miles by main road access from a tertiary obstetric unit. Methods: Following appropriate NHS and University ethical approval, an anonymous retrospective review of consecutive maternity records for all women who accessed care at the CMUs over a 12 month period (June 2011 to May 2012) was undertaken in 2013 -14. Data was extracted using variables chosen to provide a description of the socio-demographics of the cohort and the process and outcomes of the care provided. Data were analysed using descriptive statistics. Results: Regarding effectiveness, the correct care pathway was allocated to 97.5% of women, early access to antenatal care achieved by 95.7% of women, 94.8% of women at one CMU received continuity of carer and 78.6% of those clinically eligible accessed care in labour. 11.9% were appropriately transferred to obstetrician-led care antenatally and 16.9% were transferred in labour. All women received one-to one care in labour and 67.1% of babies born at the CMUs were breastfed at birth. Regarding safety, severe morbidity for women was rare, perineal trauma of 3rd degree tear occurred for 0.3% of women and 1.0% experienced an episiotomy. Severe post partum haemorrhage occurred for 0.3% of women. Babies admitted to the Neonatal unit were discharged within 48 hours. Conclusion: These findings support the recommendations of professional bodies and national guidelines. Maternity service provision at rural CMUs achieved a consistently high standard of safety and effectiveness when measured against national standards and international evidence

Severe male infertility after failed ICSI treatment-a phenomenological study of men's experiences

<p>Abstract</p> <p>Background</p> <p>Male-factor infertility underlies approximately 30% of infertility in couples seeking treatment; of which 10% is due to azoospermia. The development of assisted reproductive technology (ART), enabling the use of epididymal or testicular sperm for fertilization of the partner's oocytes, has made biological fatherhood possible for men with obstructive azoospermia. There is limited knowledge of men's experience of their own infertility. The aim of this study was to describe men's experiences of obstructive azoospermia infertility.</p> <p>Methods</p> <p>Eight men with obstructive azoospermia, who had terminated Swedish public health system ART treatment two years previously without subsequent childbirth, were interviewed using a descriptive phenomenological method.</p> <p>Results</p> <p>The essence of the phenomenon is expressed with a metaphor: climbing a mountain step by step with the aim of reaching the top, i.e. having a child and thus a family with a child. Four constituents are included (1) inadequacy followed by a feeling of redress (2) marginalisation, (3) chivalry (4) extension of life and starting a family as driving forces.</p> <p>Conclusions</p> <p>Knowledge of men's experiences of their own infertility is important as a supporting measure to increase the quality of care of infertile couples. By adopting this facet of gender perspective in fertility treatment guidelines, care can hopefully be optimized.</p

Association of a sequence variant in DAB2IP with coronary heart disease

Aims: A sequence variant, rs7025486[A], in DAB2IP on chromosome 9q33 has recently been associated with coronary heart disease (CHD). We sought to replicate this finding and to investigate associations with a panel of inflammatory and haemostatic biomarkers. We also sought to examine whether this variant, in combination with a chromosome 9p21 CHD variant (rs10757278) and the Framingham risk score (FRS), could improve the prediction of events compared with the FRS alone. Methods and results: rs7025486 was genotyped in 1386 CHD cases and 3532 controls and was associated with CHD [odds ratio (OR) of 1.16, 95% confidence interval (CI) 1.05-1.29, P = 0.003]. Meta-analysis, using data from the original report and from genome-wide association studies in both the Wellcome Trust Case Control Consortium and the Cardiovascular Health Study, comprising 9968 cases and 20 048 controls, confirmed the association (OR of 1.10, 95% CI 1.06-1.14, P = 3.2 x 10 -6). There was no association with a panel of CHD biomarkers, including any lipid, inflammation, or coagulation trait, nor with telomere length. Addition to the FRS of this variant plus rs10757278 on chromosome 9p21 improved the area under the receiver-operating characteristic curve (AROC) from 0.61 to 0.64 (P = 0.03) as well as improving the reclassification (net reclassification index = 11.1%, P = 0.007). Conclusion: This study replicates a previous association of a variant in DAB2IP with CHD. Addition of multiple variants improves the performance of predictive models based upon classical cardiovascular risk factors

Rab6 and Rab11 Regulate Chlamydia trachomatis Development and Golgin-84-Dependent Golgi Fragmentation

Many intracellular pathogens that replicate in special membrane bound compartments exploit cellular trafficking pathways by targeting small GTPases, including Rab proteins. Members of the Chlamydiaceae recruit a subset of Rab proteins to their inclusions, but the significance of these interactions is uncertain. Using RNA interference, we identified Rab6 and Rab11 as important regulators of Chlamydia infections. Depletion of either Rab6 or Rab11, but not the other Rab proteins tested, decreased the formation of infectious particles. We further examined the interplay between these Rab proteins and the Golgi matrix components golgin-84 and p115 with regard to Chlamydia-induced Golgi fragmentation. Silencing of the Rab proteins blocked Chlamydia-induced and golgin-84 knockdown-stimulated Golgi disruption, whereas Golgi fragmentation was unaffected in p115 depleted cells. Interestingly, p115-induced Golgi fragmentation could rescue Chlamydia propagation in Rab6 and Rab11 knockdown cells. Furthermore, transport of nutrients to Chlamydia, as monitored by BODIPY-Ceramide, was inhibited by Rab6 and Rab11 knockdown. Taken together, our results demonstrate that Rab6 and Rab11 are key regulators of Golgi stability and further support the notion that Chlamydia subverts Golgi structure to enhance its intracellular development

Multiple Phosphatidylinositol 3-Kinases Regulate Vaccinia Virus Morphogenesis

Poxvirus morphogenesis is a complex process that involves the successive wrapping of the virus in host cell membranes. We screened by plaque assay a focused library of kinase inhibitors for those that caused a reduction in viral growth and identified several compounds that selectively inhibit phosphatidylinositol 3-kinase (PI3K). Previous studies demonstrated that PI3Ks mediate poxviral entry. Using growth curves and electron microscopy in conjunction with inhibitors, we show that that PI3Ks additionally regulate morphogenesis at two distinct steps: immature to mature virion (IMV) transition, and IMV envelopment to form intracellular enveloped virions (IEV). Cells derived from animals lacking the p85 regulatory subunit of Type I PI3Ks (p85α−/−β−/−) presented phenotypes similar to those observed with PI3K inhibitors. In addition, VV appear to redundantly use PI3Ks, as PI3K inhibitors further reduce plaque size and number in p85α−/−β−/− cells. Together, these data provide evidence for a novel regulatory mechanism for virion morphogenesis involving phosphatidylinositol dynamics and may represent a new therapeutic target to contain poxviruses

Expression of Linear and Novel Circular Forms of an INK4/ARF-Associated Non-Coding RNA Correlates with Atherosclerosis Risk

Human genome-wide association studies have linked single nucleotide polymorphisms (SNPs) on chromosome 9p21.3 near the INK4/ARF (CDKN2a/b) locus with susceptibility to atherosclerotic vascular disease (ASVD). Although this locus encodes three well-characterized tumor suppressors, p16INK4a, p15INK4b, and ARF, the SNPs most strongly associated with ASVD are ∼120 kb from the nearest coding gene within a long non-coding RNA (ncRNA) known as ANRIL (CDKN2BAS). While individuals homozygous for the atherosclerotic risk allele show decreased expression of ANRIL and the coding INK4/ARF transcripts, the mechanism by which such distant genetic variants influence INK4/ARF expression is unknown. Here, using rapid amplification of cDNA ends (RACE) and analysis of next-generation RNA sequencing datasets, we determined the structure and abundance of multiple ANRIL species. Each of these species was present at very low copy numbers in primary and cultured cells; however, only the expression of ANRIL isoforms containing exons proximal to the INK4/ARF locus correlated with the ASVD risk alleles. Surprisingly, RACE also identified transcripts containing non-colinear ANRIL exonic sequences, whose expression also correlated with genotype and INK4/ARF expression. These non-polyadenylated RNAs resisted RNAse R digestion and could be PCR amplified using outward-facing primers, suggesting they represent circular RNA structures that could arise from by-products of mRNA splicing. Next-generation DNA sequencing and splice prediction algorithms identified polymorphisms within the ASVD risk interval that may regulate ANRIL splicing and circular ANRIL (cANRIL) production. These results identify novel circular RNA products emanating from the ANRIL locus and suggest causal variants at 9p21.3 regulate INK4/ARF expression and ASVD risk by modulating ANRIL expression and/or structure
