Breeding losses of red grouse in Glen Esk (NE Scotland): Comparative studies, 30 years on
Hatching success, brood survival and predation rates of red grouse chicks were examined at four sites in north-east Scotland over two years (1994--1995). Two of these sites have previously been the focus of a large-scale population study on grouse during the late 1950s enabling a comparison to be made. A total of 85 hens were radio-tracked and their breeding success monitored over the two years. Compared with studies undertaken in the 1950s, mean clutch size had risen from 7.2 to 8.6 eggs. Of the 76 nests monitored, 17 (22.4%) broods were lost either through egg or chick predation or by the adult being taken by a predator during incubation. Stoats appeared to be responsible for the largest amount of egg predation. There was a significant increase in predation levels, although hatching success was not significantly different from the 1950s. Chick mortality was highest within the first ten days, a similar result to that found in the 1950s. Overall, mean brood survival from hatching to 20 days was 55.1%. Possible reasons for larger clutch sizes, and the apparent increase in predation levels, are discussed
The role of lambs in louping-ill virus amplification
In some areas of Scotland, the prevalence of louping-ill virus has not decreased despite the vaccination of replacement ewes for over 30 years. The role of unvaccinated lambs in viral persistence was examined through a combination of an empirical study of infection rates of lambs and mathematical modelling. Serological sampling revealed that most lambs were protected by colostral immunity at turnout in May/June but were fully susceptible by the end of September. Between 8 and 83% of lambs were infected over the first season, with seroconversion rates greater in late rather than early summer. The proportion of lambs that could have amplified the louping-ill virus was low, however, because high initial titres of colostral antibody on farms with a high force of infection gave protection for several months. A simple mathematical model suggested that the relationship between the force of infection and the percentage of lambs that became viraemic was not linear and that the maximum percentage of viraemic lambs occurred at moderately high infection rates. Examination of the conditions required for louping-ill persistence suggested that the virus could theoretically persist in a sheep flock with over 370 lambs, if the grazing season was longer than 130 days. In practice, however, lamb viraemia is not a general explanation for louping-ill virus persistence as these conditions are not met in most management systems and because the widespread use of acaracides in most tick-affected hill farming systems reduces the number of ticks feeding successfully

Laboratory Observation of Waves in the Vicinity of WEC-Arrays
This paper was presented at the 9th European Wave and Tidal Energy Conference held in Southampton, UK September 4-11, 2011.The ocean deployment of multiple Wave Energy Converters (WECs) in large-scale arrays appears imminent. However, there is a significant gap in our present knowledge of the near-field scattering and potential far-field environmental effects due to WEC-arrays. This gap comes from the lack of observational data. To help fill this data gap, we have performed laboratory experiments using five, moored, point-absorber WECs. These WECs are 1:33 scale models of the commercially-designed “Manta” from Columbia Power Technologies
Cluster-randomised controlled trial of community mobilisation in Mumbai slums to improve care during pregnancy, delivery, postpartum and for the newborn
Background: The United Nations Millennium Development Goals look to substantial improvements in child and maternal survival. Morbidity and mortality during pregnancy, delivery and the postnatal period are prime obstacles to achieving these goals. Given the increasing importance of urban health to global prospects, Mumbai's City Initiative for Newborn Health aims to improve maternal and neonatal health in vulnerable urban slum communities, through a combination of health service quality improvement and community participation. The protocol describes a trial of community intervention aimed at improving prevention, care seeking and outcomes.Objective: To test an intervention that supports local women as facilitators in mobilising communities for better health care. Community women's groups will build an understanding of their potential to improve maternal and infant health, and develop and implement strategies to do so.Design: Cluster-randomized controlled trial.Methods: The intervention will employ local community-based female facilitators to convene groups and help them to explore maternal and neonatal health issues. Groups will meet fortnightly through a seven-phase process of sharing experiences, discussion of the issues raised, discovery of potential community strengths, building of a vision for action, design and implementation of community strategies, and evaluation.The unit of allocation will be an urban slum cluster of 1000-1500 households. 48 clusters have been randomly selected after stratification by ward. 24 clusters have been randomly allocated to receive the community intervention. 24 clusters will act as control groups, but will benefit from health service quality improvement. Indicators of effect will be measured through a surveillance system implemented by the project. Key distal outcome indicators will be neonatal mortality and maternal and neonatal morbidity. Key proximate outcome indicators will be home care practices, uptake of antenatal, delivery and postnatal care, and care for maternal and neonatal illness.Data will be collected through a vital registration system for births and deaths in the 48 study clusters. Structured interviews with families will be conducted at about 6 weeks after index deliveries. We will also collect both quantitative and qualitative data to support a process evaluation.Trial registration: Current controlled trials ISRCTN9625679
Progress along developmental tracks for electronic health records implementation in the United States
The development and implementation of electronic health records (EHR) have occurred slowly in the United States. To date, these approaches have, for the most part, followed four developmental tracks: (a) Enhancement of immunization registries and linkage with other health records to produce Child Health Profiles (CHP), (b) Regional Health Information Organization (RHIO) demonstration projects to link together patient medical records, (c) Insurance company projects linked to ICD-9 codes and patient records for cost-benefit assessments, and (d) Consortia of EHR developers collaborating to model systems requirements and standards for data linkage. Until recently, these separate efforts have been conducted in the very silos that they had intended to eliminate, and there is still considerable debate concerning health professionals access to as well as commitment to using EHR if these systems are provided. This paper will describe these four developmental tracks, patient rights and the legal environment for EHR, international comparisons, and future projections for EHR expansion across health networks in the United States
Hypertensive disorders of pregnancy and long-term cardiovascular health : FIGO best practice advice
Hypertensive disorders of pregnancy (HDP) are the most common causes of maternal
and perinatal morbidity and mortality. They are responsible for 16% of maternal
deaths in high-income
countries and approximately 25% in low-and
middle-income
countries. The impact of HDP can be lifelong as they are a recognized risk factor
for future cardiovascular disease. During pregnancy, the cardiovascular system undergoes
significant adaptive changes that ensure adequate uteroplacental blood flow
and exchange of oxygen and nutrients to nurture and accommodate the developing
fetus. Failure to achieve normal cardiovascular adaptation is associated with the development
of HDP. Hemodynamic alterations in women with a history of HDP can
persist for years and predispose to long-term
cardiovascular morbidity and mortality.
Therefore, pregnancy and the postpartum period are an opportunity to identify
women with underlying, often unrecognized, cardiovascular risk factors. It is important
to develop strategies with lifestyle and therapeutic interventions to reduce the
risk of future cardiovascular disease in those who have a history of HDP.http://wileyonlinelibrary.com/journal/ijgoam2024Obstetrics and GynaecologySDG-03:Good heatlh and well-bein
Using FIGO nutrition checklist counselling in pregnancy : a review to support healthcare professionals
The period before and during pregnancy is increasingly recognized as an important
stage for addressing malnutrition. This can help to reduce the risk of noncommunicable
diseases in mothers and passage of risk to their infants. The FIGO Nutrition
Checklist is a tool designed to address these issues. The checklist contains questions
on specific dietary requirements, body mass index, diet quality, and micronutrients.
Through answering these questions, awareness is generated, potential risks are identified,
and information is collected that can inform health-promoting
conversations
between women and their healthcare professionals. The tool can be used across a
range of health settings, regions, and life stages. The aim of this review is to summarize
nutritional recommendations related to the FIGO Nutrition Checklist to support
healthcare providers using it in practice. Included is a selection of global dietary recommendations
for each of the components of the checklist and practical insights from
countries that have used it. Implementation of the FIGO Nutrition Checklist will help
identify potential nutritional deficiencies in women so that they can be addressed by
healthcare providers. This has potential longstanding benefits for mothers and their
children, across generations.Open access funding provided by IReL.http:// wileyonlinelibrary.com/journal/ijgoam2024Obstetrics and GynaecologySDG-02:Zero HungerSDG-03:Good heatlh and well-bein
Management of obesity across women's life course : FIGO best practice advice
Obesity is a chronic, progressive, relapsing, and treatable multifactorial, neurobehavioral
disease. According to the World Health Organization, obesity affects 15% of women
and has long-term
effects on women's health. The focus of care in patients with obesity
should be on optimizing health outcomes rather than on weight loss. Appropriate
and common language, considering cultural sensitivity and trauma-informed
care, is
needed to discuss obesity. Pregnancy is a time of significant physiological change. Pre-,
ante-,
and postpartum clinical encounters provide opportunities for health optimization
for parents with obesity in terms of, but not limited to, fertility and breastfeeding.
Pre-existing
conditions may also be identified and managed. Beyond pregnancy, women
with obesity are at an increased risk for gastrointestinal and liver diseases, impaired
kidney function, obstructive sleep apnea, and venous thromboembolism. Gynecological
and reproductive health of women living with obesity cannot be dismissed, with accommodations
needed for preventive health screenings and consideration of increased
risk for gynecologic malignancies. Mental wellness, specifically depression, should be
screened and managed appropriately. Obesity is a complex condition and is increasing
in prevalence with failure of public health interventions to achieve significant decrease.
Future research efforts should focus on interprofessional care and discovering effective
interventions for health optimization.The Canadian Institutes for Health Research and the Crohns and Colitis Foundation of Canada, the European Commission Horizon 2020, National Health and Medical Research Council of Australia, Health Research Board Ireland, Al Qasimi Foundation, University of Sharjah, AstraZeneca, Bayer, Novo Nordisk, Pfizer, Tricida Inc., Phillips Health Care, Mead Johnson (China), Diabetes Ireland, Thermo Fischer, Roche, and Perkin Elmer and payment from Homburg and Partner.

Pregnancy as an opportunity to prevent type 2 diabetes mellitus : FIGO best practice advice
Gestational diabetes (GDM) impacts approximately 17 million pregnancies worldwide.
Women with a history of GDM have an 8–10-
fold
higher risk of developing type 2 diabetes
and a 2-fold
higher risk of developing cardiovascular disease (CVD) compared with
women without prior GDM. Although it is possible to prevent and/or delay progression
of GDM to type 2 diabetes, this is not widely undertaken. Considering the increasing
global rates of type 2 diabetes and CVD in women, it is essential to utilize pregnancy as
an opportunity to identify women at risk and initiate preventive intervention. This article
reviews existing clinical guidelines for postpartum identification and management
of women with previous GDM and identifies key recommendations for the prevention
and/or delayed progression to type 2 diabetes for global clinical practice.A Chinese University of Hong Kong Faculty of Medicine Faculty Postdoctoral Fellowship and support from a Croucher Foundation Senior Medical Research Fellowship.

Small and sick newborn care during the COVID-19 pandemic: global survey and thematic analysis of healthcare providers' voices and experiences.
INTRODUCTION: The COVID-19 pandemic is disrupting health systems globally. Maternity care disruptions have been surveyed, but not those related to vulnerable small newborns. We aimed to survey reported disruptions to small and sick newborn care worldwide and undertake thematic analysis of healthcare providers' experiences and proposed mitigation strategies. METHODS: Using a widely disseminated online survey in three languages, we reached out to neonatal healthcare providers. We collected data on COVID-19 preparedness, effects on health personnel and on newborn care services, including kangaroo mother care (KMC), as well as disruptors and solutions. RESULTS: We analysed 1120 responses from 62 countries, mainly low and middle-income countries (LMICs). Preparedness for COVID-19 was suboptimal in terms of guidelines and availability of personal protective equipment. One-third reported routine testing of all pregnant women, but 13% had no testing capacity at all. More than 85% of health personnel feared for their own health and 89% had increased stress. Newborn care practices were disrupted both due to reduced care-seeking and a compromised workforce. More than half reported that evidence-based interventions such as KMC were discontinued or discouraged. Separation of the mother-baby dyad was reported for both COVID-positive mothers (50%) and those with unknown status (16%). Follow-up care was disrupted primarily due to families' fear of visiting hospitals (~73%). CONCLUSION: Newborn care providers are stressed and there is lack clarity and guidelines regarding care of small newborns during the pandemic. There is an urgent need to protect life-saving interventions, such as KMC, threatened by the pandemic, and to be ready to recover and build back better
