Flash Observations For Improved Teaching Quality Among Graduate Teaching Assistants In Engineering Education
To maintain high quality, when teaching practical activities at scale, sufficient Graduate Teaching Assistants (GTAs) must be employed. However, their pedagogical skills are inconsistent. This research is a pilot study to test the reliability and validity of research methods which will be scaled up in their application to the primary research to identify GTA pedagogical skills requiring further training. In the primary study, staff and GTA perspectives will be collected using surveys, and the emerging deficient skills will be further investigated using novel twenty-minute “flash” skills-based teaching observations of GTAs. Observation time will be split among the GTAs, and the focus will be on using one of the single skills identified in the surveys by GTAs across the lab rather than how an individual uses it. This paper documents a pilot study conducted to trial a selection of three bespoke observation forms based on asking questions (i.e., the observed skills). Reflections by four observers after eighteen observations indicated that twenty minutes was sufficient time to get a fair assessment of how the observed skill was being used. The format allowed researchers to give individual feedback to GTAs who requested it and provide insight regarding the use of that skill in the lab. The researchers identified two critical factors for the successful launch of the primary study; assessing the lab settings - to avoid significant interference with the teaching - and identifying when in the session GTAs are expected to use the observed skill– ensuring that the short observation is timed effectively
Internet-Based Support for Cardiovascular Disease Management
With significant declines in cardiovascular disease (CVD) mortality, attention has shifted to patient management. Programs designed to manage CVD require the involvement of health professionals for comanagement and patients' self-management. However, these programs are commonly limited to large urban centers, resulting in limited access for rural patients. The use of telehealth potentially overcomes geographical barriers and can improve access to care for patients. The current research explores how an Internet-based platform might facilitate collaboration among healthcare providers comanaging patients and enhance behavioural change in patients. Forty-eight participants were interviewed including: (a) patients (n = 12), (b) physicians (n = 11), (c) nurses (n = 13), and (d) allied health professionals (n = 10). The results were organized and analyzed in three central themes: (1) role of technology for CVD management, (2) challenges to technology adoption, and (3) incentives for technology adoption. Health care providers and patients supported future implementation of Internet-based technology support for CVD management
A sweeter way of teaching health and safety
The underpinning educational theory for practical work is that of experimental learning or 'learning by and through doing'. Hands-on practical work promotes learning as it provides students with an opportunity to put theory into practice. There are many hazards with practical work, each with an associated risk that students will encounter while they are working in the laboratory and, therefore, adequate instruction should be given before students carry out any practical work. Getting students to engage with this in the past has been difficult due to the dryness of the material. Here we show how every students sweet tooth can be used to teach them risk assessment, experimental design and embedding health and safety as part of their scientific culture
The effectiveness of the peer delivered Thinking Healthy Plus (THPP+) Programme for maternal depression and child socio-emotional development in Pakistan: study protocol for A three-year cluster randomized controlled trial (vol 17, 442, 2016)
The effectiveness of the peer-delivered Thinking Healthy PLUS (THPP plus ) Program for maternal depression and child socioemotional development in Pakistan: study protocol for a randomized controlled trial
Abstract Background The negative effects of perinatal depression on the mother and child start early and persist throughout the lifecourse (Lancet 369(9556):145–57, 2007; Am J Psychiatry 159(1):43-7, 2002; Arch Dis Child 77(2):99–101, 1997; J Pak Med Assoc 60(4):329; J Psychosoma Res 49(3):207–16, 2000; Clin Child Fam Psychol Rev 14(1):1–27, 2011). Given that 10–35% of children worldwide are exposed to perinatal depression in their first year of life (Int Rev Psychiatry 8(1):37–54, 1996), mitigating this intergenerational risk is a global public health priority (Perspect Public Health 129(5):221–7, 2009; Trop Med Int Health 13(4):579–83, 2008; Br Med Bull 101(1):57–79, 2012). However, it is not clear whether intervention with depressed women can have long-term benefits for the mother and/or her child. We describe a study of the effectiveness of a peer-delivered depression intervention delivered through 36 postnatal months, the Thinking Healthy Program Peer-delivered PLUS (THPP+) for women and their children in rural Pakistan. Methods/design The THPP+ study aims are: (1) to evaluate the effects of an extended 36-month perinatal depression intervention on maternal and index child outcomes using a cluster randomized controlled trial (c-RCT) and (2) to determine whether outcomes among index children of perinatally depressed women in the intervention arm converge with those of index children born to perinatally nondepressed women. The trial is designed to recruit 560 pregnant women who screened positive for perinatal depression (PHQ-9 score ≥10) from 40 village clusters, of which 20 receive the THPP+ intervention. An additional reference group consists of 560 perinatally nondepressed women from the same 40 clusters as the THPP+ trial. The women in the nondepressed group are not targeted to receive the THPP+ intervention; but, by recruiting pregnant women from both intervention and control clusters, we are able to evaluate any carryover effects of the THPP+ intervention on the women and their children. Perinatally depressed women in the THPP+ intervention arm receive bimonthly group-based sessions. Primary outcomes are 3-year maternal depression and 3-year child development indicators. Analyses are intention-to-treat and account for the clustered design. Discussion This trial, together with the reference group, has the potential to further our understanding of the early developmental lifecourse of children of both perinatally depressed and perinatally nondepressed women in rural Pakistan and to determine whether intervening with women’s depression in the perinatal period can mitigate the negative effects of maternal depression on 36-month child development.

Maternal anaemia care in Kano state, Nigeria: an exploratory qualitative study of experiences of uptake and provision
Background:
Maternal anaemia (anaemia in pregnancy, childbirth, and the postpartum period) remains a persistent challenge, particularly in Kano State, Nigeria, which has the highest prevalence of maternal anaemia globally, at 72%.
Methods:
We conducted a qualitative study in Murtala Muhammad Specialist Hospital in Kano State, Nigeria. We aimed to identify factors constraining uptake and provision of maternal anaemia care, exploring perspectives across different stakeholders. We carried out 10 key informant interviews with policymakers and hospital managers, 28 in-depth interviews with healthcare providers and pregnant women using antenatal services and four focus group discussions with pregnant women’s husbands and mothers-in-law. Data were analysed thematically.
Results:
Issues with provision include a lack of provider training and guidelines specific to maternal anaemia and blood transfusion, insufficient staff to meet increasing demand, and inadequate resources. Issues with uptake include the inability to afford informal user fees, distrust in health services and the blood transfusion process, and a lack of understanding of the causes, consequences, and treatment for anaemia, resulting in poor uptake of care and adherence to treatment.
Conclusions:
This study recommends the implementation of standardized guidelines and training sessions to better support healthcare providers in offering quality services and increasing funding allocated to supporting maternal anaemia care. Education initiatives for service users and the public are also recommended to build public trust in health services and to improve understanding of maternal anaemia
Effectiveness and cost effectiveness of pharmacist input at the ward level: a systematic review and meta-analysis
Background Pharmacists play important role in ensuring timely care delivery at the ward level. The optimal level of pharmacist input, however, is not clearly defined. Objective To systematically review the evidence that assessed the outcomes of ward pharmacist input for people admitted with acute or emergent illness. Methods The protocol and search strategies were developed with input from clinicians. Medline, EMBASE, Centre for Reviews and Dissemination, The Cochrane Library, NHS Economic Evaluations, Health Technology Assessment and Health Economic Evaluations databases were searched. Inclusion criteria specified the population as adults and young people (age >16 years) who are admitted to hospital with suspected or confirmed acute or emergent illness. Only randomised controlled trials (RCTs) published in English were eligible for inclusion in the effectiveness review. Economic studies were limited to full economic evaluations and comparative cost analysis. Included studies were quality-assessed. Data were extracted, summarised. and meta-analysed, where appropriate. Results Eighteen RCTs and 7 economic studies were included. The RCTs were from USA (n=3), Sweden (n=2), Belgium (n=2), China (n=2), Australia (n=2), Denmark (n=2), Northern Ireland, Norway, Canada, UK and Netherlands. The economic studies were from UK (n=2), Sweden (n=2), Belgium and Netherlands. The results showed that regular pharmacist input was most cost effective. It reduced length-of-stay (mean= -1.74 days [95% CI: -2.76, -0.72], and increased patient and/or carer satisfaction (Relative Risk (RR) =1.49 [1.09, 2.03] at discharge). At £20,000 per quality-adjusted life-year (QALY)-gained cost-effectiveness threshold, it was either cost-saving or cost-effective (Incremental Cost Effectiveness Ratio (ICER) =£632/ QALY-gained). No evidence was found for 7-day pharmacist presence. Conclusions Pharmacist inclusion in the ward multidisciplinary team improves patient safety and satisfaction and is cost-effective when regularly provided throughout the ward stay. Research is needed to determine whether the provision of 7-day service is cost-effective.Peer reviewe
Evolutionary changes in the Leishmania eIF4F complex involve variations in the eIF4E–eIF4G interactions
Translation initiation in eukaryotes is mediated by assembly of the eIF4F complex over the m7GTP cap structure at the 5′-end of mRNAs. This requires an interaction between eIF4E and eIF4G, two eIF4F subunits. The Leishmania orthologs of eIF4E are structurally diverged from their higher eukaryote counterparts, since they have evolved to bind the unique trypanosomatid cap-4 structure. Here, we characterize a key eIF4G candidate from Leishmania parasites (LeishIF4G-3) that contains a conserved MIF4G domain. LeishIF4G-3 was found to coelute with the parasite eIF4F subunits from an m7GTP-Sepharose column and to bind directly to LeishIF4E. In higher eukaryotes the eIF4E-eIF4G interaction is based on a conserved peptide signature [Y(X4)Lϕ], where X is any amino acid and Φ is a hydrophobic residue. A parallel eIF4E-binding peptide was identified in LeishIF4G-3 (20-YPGFSLDE-27). However, the binding motif varies extensively: in addition to Y20 and L25, binding strictly requires the presence of F23, whereas the hydrophobic amino acid (Φ) is dispensable. The LeishIF4E–LeishIF4G-3 interaction was also confirmed by nuclear magnetic resonance (NMR) studies. In view of these diversities, the characterization of the parasite eIF4E–eIF4G interaction may not only serve as a novel target for inhibiting Leishmaniasis but also provide important insight for future drug discovery
