The Forward Premium Anomaly: Three Examples in Search of a Solution

Perhaps the most puzzling feature of currency prices is the tendency for high interest rate currencies to appreciate, when the expectations hypothesis suggest the reverse. This forward premium anomaly has been attributed, by some, to a time-varying risk premium, but theory has yet to produce a risk premium with the requisite properties. We characterize the risk premium in a general theoretical framework and construct three examples that illustrate features a theoretical explanation of the anomaly is likely to have

Long-Term Prognostic Impact of Right Ventricular Dysfunction in Patients with COVID-19

The characteristics and clinical course of hospitalized patients with coronavirus disease 2019 (COVID-19) have been widely described, while long-term data are still poor. The aim of this study was to evaluate the long-term clinical outcome and its association with right ventricular (RV) dysfunction in hospitalized patients with COVID-19. This was a prospective multicenter study of consecutive COVID-19 patients hospitalized at seven Italian Hospitals from 28 February to 20 April 2020. The study population was divided into two groups according to echocardiographic evidence of RV dysfunction. The primary study outcome was 1-year mortality. The propensity score matching was performed to balance for potential baseline confounders. The study population consisted of 224 patients (mean age 69 \ub1 14, male sex 62%); RV dysfunction was diagnosed in 63 cases (28%). Patients with RV dysfunction were older (75 vs. 67 years, p < 0.001), had higher prevenance of coronary artery disease (27% vs. 11%, p = 0.003), and lower left ventricular ejection fraction (50% vs. 55%, p <0.001). The rate of 1-year mortality (67% vs. 28%; p 64 0.001) was significantly higher in patients with RV dysfunction compared with patients without. After propensity score matching, patients with RV dysfunction showed a worse long-term survival (62% vs. 29%, p <0.001). The multivariable Cox regression model showed an independent association of RV dysfunction with 1-year mortality. RV dysfunction is a relatively common finding in hospitalized COVID-19 patients, and it is independently associated with an increased risk of 1-year mortality

IMPRESS: Improving Engagement in Software Engineering Courses through Gamification

Software Engineering courses play an important role for preparing students with the right knowledge and attitude for software development in practice. The implication is far reaching, as the quality of the software that we use ultimately depends on the quality of the people that make them. Educating Software Engineering, however, is quite challenging, as the subject is not considered as most exciting by students, while teachers often have to deal with exploding number of students. The EU project IMPRESS seeks to explore the use of gamification in educating software engineering at the university level to improve students' engagement and hence their appreciation for the taught subjects. This paper presents the project, its objectives, and its current progress

The effect of becoming a Fistula Advocate on the recovery of women with Obstetric Fistula in Sierra Leone: A qualitative study.

Engaging women affected by Obstetric Fistula as advocates has been proposed as an effective strategy to raise awareness of the condition. Limited literature exists on the experience of those who become advocates. A model of community education, in Sierra Leone, trained women affected by Obstetric Fistula to become volunteer Fistula Advocates. This study explored Advocates' perception of their role and its influence on their recovery and reintegration. This was a qualitative study, undertaken in Sierra Leone, collecting data from 7 Fistula Advocates and 3 Key Informants (with roles in either clinical or outreach care for women with Obstetric Fistula or training and supervision of Advocates), using semi-structured interviews. Data was subject to a thematic analysis and related to a conceptual framework for mental health recovery. Intrinsic factors motivating Advocates to undertake this role were influenced by psycho-social support received and the possibility for financial independence. Advocates used personal stories in their work to define a new identity, change perceptions and reduce stigma. Benefits associated with the interactions and relationships created through providing and receiving peer support were voiced. Surgical treatment was described as an important factor influencing recovery. The Advocates said economic empowerment helped recovery and reintegration, and the voluntary nature of the Advocate role limited the impact of this. Overall Advocates perceived their role positively, reporting psychological, social, and economic benefits. The complexities of recovery from Obstetric Fistula were highlighted and connections drawn between the treatment of physical symptoms, the socio-cultural context and mental health recovery. They described the role positively influencing existing relationships and initiating supportive, empowering social interactions between women affected by Obstetric Fistula and with Non-Governmental Organisation staff and community members. The study offers insights into the potential for community-based approaches to facilitate access to treatment for sensitive and stigmatising health problems and support recovery

Iron supplementation of breastfed Gambian infants from 6 weeks to 6 months of age: protocol for a randomised controlled trial

Background: A recent analysis showed that plasma iron concentrations decline rapidly from birth in Gambian infants, irrespective of sex or birthweight, to concentrations well below normal expected values for iron-replete children older than two months of age (typically >10 μmol/L). The development and function of neural and immune cells may thus be compromised before the minimum age at which children should receive iron supplementation as per World Health Organisation recommendations. Methods: This study is a two-arm, double-blind, placebo-controlled, randomised superiority trial. Infants will be randomised to receive iron drops (7.5mg/day of iron as ferrous sulphate) or placebo daily for 98 days, to test the impact on serum iron concentrations in healthy, breastfed infants (n = 100) aged 6-10 weeks at enrolment. Participants will be visited daily and supplemented by the field team. Daily health and weekly breastfeeding questionnaires will be administered. Anthropometry, and venous blood and faecal samples will be collected at enrolment and after 98 days of supplementation with serum iron as the primary endpoint. Low birthweight (less than 2.5kg at birth) and infants born prematurely (< 37 weeks) will not be excluded. Formula-fed and infants with any illness will be excluded. An additional study exploring maternal stakeholder perspectives of the intervention will be conducted by means of maternal interviews and four focus group discussions with local stakeholders. Discussion: Most breast-fed Gambian infants have very low circulating iron levels by five months of age. This study will introduce iron supplements much earlier in infancy than has previously been attempted in a low-income setting with the primary aim of increasing serum iron concentration. Trial registration: Clincaltrials.gov (NCT04751994); 12th February 202

Maternal acceptability of iron supplementation in young breastfed rural Gambian infants

Introduction A recent analysis of Gambian infants showed that plasma iron concentrations decline rapidly from birth to levels below the 95% reference range within 5 months of age. To address this issue, a clinical trial was initiated to assess the efficacy of early iron supplementation in breastfed infants under 6 months of age (‘Iron Babies’; NCT04751994). To understand if such an intervention is feasible for scaleup, the acceptability, through the lens of local stakeholders and mothers (as the primary caregiver), must be considered. Methods An embedded qualitative study, therefore, explored acceptability through focus group discussions with local stakeholders and interviews with mothers. Four focus group discussions with local stakeholders (n = 19) and individual interviews (n = 14) with mothers whose infants were enrolled in the clinical trial were conducted. Qualitative data were analysed with respect to an implementation acceptability framework using Template Analysis. Results From the focus group discussions, there was a general sense of enthusiasm for the intervention, but also a concern due to confusion around nutritional messaging. The intervention was acceptable to mothers with limited mention of side effects and enthusiasm for participating in clinical trials on iron supplementation. However, when looking at scaleup, there were mixed opinions on the practicality of daily supplementation, as well as concerns around costs. In addition, it was suggested that proper dissemination of information and inclusion of all family members in decision-making, especially fathers, is key to acceptability. Conclusion There was no indication that stakeholders or mothers were resistant to iron supplementation of breastfed infants

On race and ethnicity during a global pandemic: An ‘imperfect mosaic’ of maternal and child health services in ethnically-diverse South London, United Kingdom

Background: The SARS-CoV-2 pandemic has brought racial and ethnic inequity into sharp focus, as Black, Asian, and Minority Ethnic people were reported to have greater clinical vulnerability. During the pandemic, priority was given to ongoing, reconfigured maternity and children's healthcare. This study aimed to understand the intersection between race and ethnicity, and healthcare provision amongst maternity and children's healthcare professionals, during the SARS-CoV-2 pandemic. Methods: A qualitative study consisting of semi-structured interviews (N = 53) was undertaken with maternity (n = 29; August-November 2020) and children's (n = 24; June-July 2021) healthcare professionals from an NHS Trust in ethnically-diverse South London, UK. Data pertinent to ethnicity and race were subject to Grounded Theory Analysis, whereby data was subjected to iterative coding and interpretive analysis. Using this methodology, data are compared between transcripts to generate lower and higher order codes, before super-categories are formed, which are finally worked into themes. The inter-relationship between these themes is interpreted as a final theory. Findings: Grounded Theory Analysis led to the theory: An ‘Imperfect Mosaic’, comprising four themes: (1) ‘A System Set in Plaster’; (2) ‘The Marginalised Majority’; (3) ‘Self-Discharging Responsibility for Change-Making’; and (4) ‘Slow Progress, Not No Progress’. The NHS was observed to be brittle, lacking plasticity to deliver change at pace. Overt racism based on skin colour has been replaced by micro-aggressions between in-groups and out-groups, defined not just by ethnicity, but by other social determinants. Contemporaneously, responsibility for health, wellbeing, and psychological safety in the workplace is discharged to, and accepted by, the individual. Interpretation: Our findings suggest three practicable solutions: (1) Representation of marginalised groups at all NHS levels; (2) Engagement in cultural humility which extends to other social factors; and (3) Collective action at system and individual levels, including prioritising equity over simplistic notions of equality. Funding: This service evaluation was supported by the King's College London King's Together Rapid COVID-19 Call, successfully awarded to Laura A. Magee, Sergio A. Silverio, Abigail Easter, & colleagues (reference:- 204823/Z/16/Z), as part of a rapid response call for research proposals. The King's Together Fund is a Wellcome Trust funded initiative

Resource allocation of in vitro fertilization: a nationwide register-based cohort study

<p>Abstract</p> <p>Background</p> <p>Infertility is common and in vitro fertilization (IVF) is a widely used treatment. In IVF the need increases and the effectiveness and appropriateness decrease by age. The purpose of this study was to describe allocation of resources for IVF by women's age, socioeconomic position, area of residence and treatment sector (public vs. private) and to discuss how fairly the IVF resources are allocated in Finland.</p> <p>Methods</p> <p>Women who received IVF between 1996 and 1998 (N = 9175) were identified from the reimbursement records of the Social Insurance Institution (SII). Information on IVF women's background characteristics came from the Central Population Register and the SII, on treatment costs from IVF clinics and the SII, and on births from the Medical Birth Register. The main outcome measures were success of IVF by number of cycles and treated women, expenditures per IVF cycles, per women, per live-birth, and per treatment sector, and private and public expenditures. Expenditures were estimated from health care visits and costs.</p> <p>Results</p> <p>During a mean period of 1.5 years, older women (women aged 40 or older) received 1.4 times more IVF treatment cycles than younger women (women aged below 30). The success rate decreased by age: from 22 live births per 100 cycles among younger women to 6 per 100 among older women. The mean cost of a live birth increased by age: compared to younger women, costs per born live birth of older women were 3-fold. Calculated by population, public expenditure was allocated most to young women and women from the highest socioeconomic position. Regional differences were not remarkable.</p> <p>Conclusion</p> <p>Children of older infertile women involve more expense due to the lower success rates of IVF. Socioeconomic differences suggest unfair resource allocation in Finland.</p
