BACKGROUND: Women who suffer an early pregnancy loss require specific clinical care, aftercare, and ongoing support. In the UK, the clinical management of early pregnancy complications, including loss is provided mainly through specialist Early Pregnancy Assessment Units. The COVID-19 pandemic fundamentally changed the way in which maternity and gynaecological care was delivered, as health systems moved to rapidly reconfigure and re-organise services, aiming to reduce the risk and spread of SARS-CoV-2 infection. PUDDLES is an international collaboration investigating the pandemic's impact on care for people who suffered a perinatal bereavement. Presented here are initial qualitative findings undertaken with UK-based women who suffered early pregnancy losses during the pandemic, about how they navigated the healthcare system and its restrictions, and how they were supported. METHODS: In-keeping with a qualitative research design, in-depth semi-structured interviews were undertaken with an opportunity sample of women (N = 32) who suffered any early pregnancy loss during the COVID-19 pandemic. Data were analysed using a template analysis to understand women's access to services, care, and networks of support, during the pandemic following their pregnancy loss. The thematic template was based on findings from parents who had suffered a late-miscarriage, stillbirth, or neonatal death in the UK, during the pandemic. RESULTS: All women had experienced reconfigured maternity and early pregnancy services. Data supported themes of: 1) COVID-19 Restrictions as Impractical & Impersonal; 2) Alone, with Only Staff to Support Them; 3) Reduction in Service Provision Leading to Perceived Devaluation in Care; and 4) Seeking Their Own Support. Results suggest access to early pregnancy loss services was reduced and pandemic-related restrictions were often impractical (i.e., restrictions added to burden of accessing or receiving care). Women often reported being isolated and, concerning

INTRODUCTION: Globally, the COVID-19 pandemic has significantly disrupted the provision of healthcare and efficiency of healthcare systems and is likely to have profound implications for pregnant and postpartum women and their families including those who experience the tragedy of stillbirth or neonatal death. This study aims to understand the psychosocial impact of COVID-19 and the experiences of parents who have accessed maternity, neonatal and bereavement care services during this time. METHODS AND ANALYSIS: An international, cross-sectional, online and/or telephone-based/face-to-face survey is being administered across 15 countries and available in 11 languages. New, expectant and bereaved parents during the COVID-19 pandemic will be recruited. Validated psychometric scales will be used to measure psychosocial well-being. Data will be analysed descriptively and by assessing multivariable associations of the outcomes with explanatory factors. In seven of these countries, bereaved parents will be recruited to a nested, qualitative interview study. The data will be analysed using a grounded theory analysis (for each country) and thematic framework analysis (for intercountry comparison) to gain further insights into their experiences. ETHICS AND DISSEMINATION: Ethics approval for the multicountry online survey, COCOON, has been granted by the Mater Misericordiae Human Research Ethics Committee in Australia (reference number: AM/MML/63526). Ethics approval for the nested qualitative interview study, PUDDLES, has been granted by the King's College London Biomedical & Health Sciences, Dentistry, Medicine and Natural & Mathematical Sciences Research Ethics Subcommittee (reference number: HR-19/20-19455) in the UK. Local ethics committee approvals were granted in participating countries where required. Results of the study will be published in international peer-reviewed journals and through parent support organisations. Findings will contribute to our understanding of d

BACKGROUND: The COVID-19 pandemic poses an unprecedented risk to the global population. Maternity care in the UK was subject to many iterations of guidance on how best to reconfigure services to keep women, their families and babies, and healthcare professionals safe. Parents who experience a pregnancy loss or perinatal death require particular care and support. PUDDLES is an international collaboration investigating the experiences of recently bereaved parents who suffered a late miscarriage, stillbirth, or neonatal death during the global COVID-19 pandemic, in seven countries. In this study, we aim to present early findings from qualitative work undertaken with recently bereaved parents in the United Kingdom about how access to healthcare and support services was negotiated during the pandemic. METHODS: In-depth semi-structured interviews were undertaken with parents (N = 24) who had suffered a late miscarriage (n = 5; all mothers), stillbirth (n = 16; 13 mothers, 1 father, 1 joint interview involving both parents), or neonatal death (n = 3; all mothers). Data were analysed using a template analysis with the aim of investigating bereaved parents' access to services, care, and networks of support, during the pandemic after their bereavement. RESULTS: All parents had experience of utilising reconfigured maternity and/or neonatal, and bereavement care services during the pandemic. The themes utilised in the template analysis were: 1) The Shock & Confusion Associated with Necessary Restrictions to Daily Life; 2) Fragmented Care and Far Away Families; 3) Keeping Safe by Staying Away; and 4) Impersonal Care and Support Through a Screen. Results suggest access to maternity, neonatal, and bereavement care services were all significantly reduced, and parents' experiences were notably affected by service reconfigurations. CONCLUSIONS: Our findings, whilst preliminary, are important to document now, to help inform care and service provision as the pandemic continues and to p

Objective: To assess the frequency of additional care, and parents' perceptions of quality, respectful care, in pregnancies subsequent to stillbirth. Design: Multi‐language web‐based survey. Setting: International. Population: A total of 2716 parents, from 40 high‐ and middle‐income countries. Methods: Data were obtained from a broader survey of parents' experiences following stillbirth. Data were analysed using descriptive statistics and stratified by geographic region. Subgroup analyses explored variation in additional care by gestational age at index stillbirth. Main outcome measures: Frequency of additional care, and perceptions of quality, respectful care. Results: The majority (66%) of parents conceived their subsequent pregnancy within 1 year of stillbirth. Additional antenatal care visits and ultrasound scans were provided for 67% and 70% of all parents, respectively, although there was wide variation across geographic regions. Care addressing psychosocial needs was less frequently provided, such as additional visits to a bereavement counsellor (10%) and access to named care provider's phone number (27%). Compared with parents whose stillbirth occurred at ≤ 29 weeks of gestation, parents whose stillbirth occurred at ≥ 30 weeks of gestation were more likely to receive various forms of additional care, particularly the option for early delivery after 37 weeks. Around half (47-63%) of all parents felt that elements of quality, respectful care were consistently applied, such as spending enough time with parents and involving parents in decision‐making. Conclusions: Greater attention is required to providing thoughtful, empathic and collaborative care in all pregnancies following stillbirth. Specific education and training for health professionals is needed.

Summary Variation in stillbirth rates across high-income countries and large equity gaps within high-income countries persist. If all high-income countries achieved stillbirth rates equal to the best performing countries, 19 439 late gestation (28 weeks or more) stillbirths could have been avoided in 2015. The proportion of unexplained stillbirths is high and can be addressed through improvements in data collection, investigation, and classification, and with a better understanding of causal pathways. Substandard care contributes to 20-30% of all stillbirths and the contribution is even higher for late gestation intrapartum stillbirths. National perinatal mortality audit programmes need to be implemented in all high-income countries. The need to reduce stigma and fatalism related to stillbirth and to improve bereavement care are also clear, persisting priorities for action. In high-income countries, a woman living under adverse socioeconomic circumstances has twice the risk of having a stillborn child when compared to her more advantaged counterparts. Programmes at community and country level need to improve health in disadvantaged families to address these inequities.Copyright © 2016 Elsevier Ltd.

Despite the frequency of stillbirths, the subsequent implications are overlooked and underappreciated. We present findings from comprehensive, systematic literature reviews, and new analyses of published and unpublished data, to establish the effect of stillbirth on parents, families, health-care providers, and societies worldwide. Data for direct costs of this event are sparse but suggest that a stillbirth needs more resources than a livebirth, both in the perinatal period and in additional surveillance during subsequent pregnancies. Indirect and intangible costs of stillbirth are extensive and are usually met by families alone. This issue is particularly onerous for those with few resources. Negative effects, particularly on parental mental health, might be moderated by empathic attitudes of care providers and tailored interventions. The value of the baby, as well as the associated costs for parents, families, care providers, communities, and society, should be considered to prevent stillbirths and reduce associated morbidity.

BACKGROUND: Stillbirths and neonatal deaths are devastating events for both parents and clinicians and are global public health concerns. Careful clinical management after these deaths is required, including appropriate investigation and assessment to determine cause (s) to prevent future losses, and to improve bereavement care for families. An educational programme for health care professionals working in maternal and child health has been designed to address these needs according to the Perinatal Society of Australia and New Zealand Guideline for Perinatal Mortality: IMproving Perinatal mortality Review and Outcomes Via Education (IMPROVE). The programme has a major focus on stillbirth and is delivered as six interactive skills-based stations. We aimed to determine participants' pre- and post-programme knowledge of and confidence in the management of perinatal deaths, along with satisfaction with the programme. We also aimed to determine suitability for international use. METHODS: The IMPROVE programme was delivered to health professionals in maternity hospitals in all seven Australian states and territories and modified for use internationally with piloting in Vietnam, Fiji, and the Netherlands (with the assistance of the International Stillbirth Alliance, ISA). Modifications were made to programme materials in consultation with local teams and included translation for the Vietnam programme. Participants completed pre- and post-programme evaluation questionnaires on knowledge and confidence on six key components of perinatal death management as well as a satisfaction questionnaire. RESULTS: Over the period May 2012 to May 2015, 30 IMPROVE workshops were conducted, including 26 with 758 participants in Australia and four with 136 participants internationally. Evaluations showed a significant improvement between pre- and post-programme knowledge and confidence in all six stations and overall, and a high degree of satisfaction in all settings. CONCLUSIONS: The IMPRO

U-Pb detrital zircon data show that the East Mainland Succession, the presumed correlative of the Dalradian Supergroup in the Shetland Islands, Scotland, is dominated by Mesoproterozoic and Archaean material, with some Palaeoproterozoic detritus. The data are most consistent with derivation from eastern Laurentia, although western Baltica sources cannot be excluded. A magmatic event at c. 576 Ma supplied detritus to the Clift Hills Group, and was the source of high-temperature fluids that resulted in growth of new metamorphic zircon, and altered old detrital grains within the underlying sedimentary pile. This provides a constraint on the age of the global Shuram-Wonaka event recognized within the Whiteness Group, which underlies the Clift Hills Group. The presence of common Archaean detritus is compatible with broad timecorrelation of the East Mainland Succession with the Dalradian Supergroup. However, differences in age, thickness and basin evolution are consistent with deposition in separate basins along the extending Laurentian margin during supercontinent break-up and development of the Iapetus Ocean. Similarities in the detrital zircon records of the East Mainland Succession and the offshore Devonian-Carboniferous Clair Group permit derivation, at least in part, of the latter from the Shetland Islands and proximal sources on the adjacent continental shelf.

The PICASSO experiment at SNOLAB reports new results for spin-dependent WIMP interactions on $^{19}$F using the superheated droplet technique. A new generation of detectors and new features which enable background discrimination via the rejection of non-particle induced events are described. First results are presented for a subset of two detectors with target masses of $^{19}$F of 65 g and 69 g respectively and a total exposure of 13.75 $\pm$ 0.48 kgd. No dark matter signal was found and for WIMP masses around 24 GeV/c$^2$ new limits have been obtained on the spin-dependent cross section on $^{19}$F of $\sigma_F$ = 13.9 pb (90% C.L.) which can be converted into cross section limits on protons and neutrons of $\sigma_p$ = 0.16 pb and $\sigma_n$ = 2.60 pb respectively (90% C.L). The obtained limits on protons restrict recent interpretations of the DAMA/LIBRA annual modulations in terms of spin-dependent interactions., Comment: Revised version, accepted for publication in Phys.

The PICASSO collaboration observed for the first time a significant difference between the acoustic signals induced by neutrons and alpha particles in a detector based on superheated liquids. This new discovery offers the possibility of improved background suppression and could be especially useful for dark matter experiments. This new effect may be attributed to the formation of multiple bubbles on alpha tracks, compared to single nucleations created by neutron induced recoils., Comment: 7 pages, 4 figures. accepted for publication in New Journal of Physics

Combining Lu–Hf garnet geochronology with in situ trace element analyses in garnet allowed us to gain new insight into the metamorphic evolution of UHP–UHT rocks in the Stary Gierałtów region, in the Polish Sudetes. Prograde garnet growth recorded by Rayleigh-type heavy REE (HREE) zoning in the felsic granulites indicates that the obtained 386.6±4.9 Ma Lu–Hf age represents the time of garnet crystallization on a prograde UHP metamorphic path. The surrounding rocks were metamorphosed at the same time as indicated by 381.2±6.7 Ma Sm–Nd garnet age obtained for the mid-crustal metapelites. The second metamorphic episode, which affected most of the lower crust in the Orlica–Śnieżnik Massif (OSM) occurred at ca. 340 Ma as determined by U–Pb zircon and Sm–Nd garnet dating of granulites in this and previous studies is interpreted as a high temperature event, which took place on a retrograde path. Trace element distribution in garnets from the layered granulites showed significant differences in distribution of medium and HREE in garnets from mafic and felsic protoliths over the course of the metamorphic evolution. This had strong impact on the isotopic dating results and led to “decoupling” of the Sm–Nd and Lu–Hf clocks, which recorded timing of the two different metamorphic episodes separated by as much as 40 Ma. Moreover, the preservation of the HREE growth zonation profile in garnets from the felsic granulites whose minimum metamorphic temperature was established at 900 °C implies that the Lu–Hf system under relatively dry conditions does not undergo significant diffusional re-equilibration even at such extreme temperatures and therefore it sill provides the age of prograde garnet growth. Under hydrous conditions, at least some resetting will take place, as documented by the partially relaxed HREE zonation profile in the amphibolitised mafic granulite, which yielded a 10 Ma younger age. The HREE distribution study appeared to be a particularly valuable and essential tool

As geochemical characterisation of orogenic gold source(s) and mineralised systems, and in particular their dating, is fraught with difficulty, rutile was investigated as a useful lode tracer. New trace-element and U-Pb geochronological data was collected from shear-hosted, gold-bearing veins from the Ouro Preto gold district in SE Brazil, using samples samples from two mines: the Passagem de Mariana and Chico Rei. Interstitial gold inclusions within rutile attest to a cogenetic crystallisation, so the age of gold mineralisation can be constrained by U-Pb rutile ages of c.502 and 485 Ma from two mines. Regionally, this implicates the Brasiliano orogenic collapse as the tectonic driving force behind the gold mineralisation of this area. Rutile trace-elemental chemistry revealed vast heterogeneity within the contemporaneous lodes, delineating the targeted mines through Cu, Cr, Sb, Sc, Sn, Nb, Nb/Ta, Zr/Hf, and W concentrations. These results show that the Brasilian orogenic collapse generated a locally heterogeneous fluid, producing temporally analogous but geochemically contrasting rutiles in the lode as a likely result of influence by local geology during fluid migration., As geochemical characterisation of orogenic gold source(s) and mineralised systems, and in particular their dating, is fraught with difficulty, rutile was investigated as a useful lode tracer.
