    Infertility, psychological distress, and coping strategies among women in Mali, West Africa: a mixed-methods study

    Relatively little is known about infertility and its consequences in Mali, West Africa where the context and culture are different from those of previously studied settings. This study therefore aimed to specifically examine infertility induced psychological distress and coping strategies among women in Mali. A convergent mixed-methods design—correlational cross-sectional and qualitative descriptive—guided the study. Fifty-eight infertile Malian women participated: 52 completed the Psychological Evaluation Test specific for infertility and a question on general health status, and 26 were interviewed in-depth. Over 20% scored above the cut-off point for psychological distress, and 48% described their general health as poor. There was no significant difference between women with primary vs. secondary infertility. The study found that infertile women lived with marital tensions, criticism from relatives, and stigmatization from the community. They experienced sadness, loneliness, and social deprivation. Coping strategies included traditional and biomedical treatments, religious faith and practices, and self-isolation. Health care professionals should provide holistic care for infertile women to meet their physical, spiritual, psychological, and social needs.Keywords: coping; infertility; psychological distress; Mali; mixed-method

    Seroprevalence of hepatitis B surface antigen among pregnant women attending the Hospital for Women & Children in Koutiala, Mali

    Objective. To establish the rate of seroprevalence of the hepatitis B surface antigen in pregnant women in south-eastern Mali, and to decrease mother-to-child transmission. Methods. In a descriptive cross-sectional comparison study, 3 659 pregnant women attending a non-governmental hospital in Koutiala, Mali, during 2008 and 2009 were screened for the hepatitis B surface antigen during antenatal clinic attendance or when admitted for delivery. A chart review compared the hepatitis B virus (HBV)-positive women to HBV-negative women used as controls to identify potential risk factors for HBsAg positivity. The variables compared were age, parity, type of genital excision, birthweight of baby and HIV status. Results. A total of 293 (8.0%) pregnant women tested positive for HBsAg. Their average age was 27.6 years, average parity of 2.8 births, 90% had Type 2 genital excision, 21% had low-birthweight infants, and 14 (0.4%) women also tested positive for HIV. Infants born to HbsAg-positive women were immunised with the hepatitis B vaccine in the delivery room. Two hundred and eighty-four HBVnegative women were compared with the HBV-positive women. None of the differences of means or relationships was statistically insignificant. Conclusion. In view of the high endemicity and lack of easily identifiable risk factors, free maternal HBV screening should be provided to all women in Mali, and the infants born to HBsAgpositive women should be immunised within 12 hours of birth.

    The wide-field, multiplexed, spectroscopic facility WEAVE : survey design, overview, and simulated implementation

    Funding for the WEAVE facility has been provided by UKRI STFC, the University of Oxford, NOVA, NWO, Instituto de Astrofísica de Canarias (IAC), the Isaac Newton Group partners (STFC, NWO, and Spain, led by the IAC), INAF, CNRS-INSU, the Observatoire de Paris, Région Île-de-France, CONCYT through INAOE, Konkoly Observatory (CSFK), Max-Planck-Institut für Astronomie (MPIA Heidelberg), Lund University, the Leibniz Institute for Astrophysics Potsdam (AIP), the Swedish Research Council, the European Commission, and the University of Pennsylvania.WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre positioner, 20 individually deployable 'mini' integral field units (IFUs), and a single large IFU. These fibre systems feed a dual-beam spectrograph covering the wavelength range 366-959 nm at R ∼ 5000, or two shorter ranges at R ∼ 20,000. After summarising the design and implementation of WEAVE and its data systems, we present the organisation, science drivers and design of a five- to seven-year programme of eight individual surveys to: (i) study our Galaxy's origins by completing Gaia's phase-space information, providing metallicities to its limiting magnitude for ∼ 3 million stars and detailed abundances for ∼ 1.5 million brighter field and open-cluster stars; (ii) survey ∼ 0.4 million Galactic-plane OBA stars, young stellar objects and nearby gas to understand the evolution of young stars and their environments; (iii) perform an extensive spectral survey of white dwarfs; (iv) survey  ∼ 400 neutral-hydrogen-selected galaxies with the IFUs; (v) study properties and kinematics of stellar populations and ionised gas in z 1 million spectra of LOFAR-selected radio sources; (viii) trace structures using intergalactic/circumgalactic gas at z > 2. Finally, we describe the WEAVE Operational Rehearsals using the WEAVE Simulator.PostprintPeer reviewe

    WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre positioner, 20 individually deployable 'mini' integral field units (IFUs), and a single large IFU. These fibre systems feed a dual-beam spectrograph covering the wavelength range 366-959\,nm at R5000R\sim5000, or two shorter ranges at R20000R\sim20\,000. After summarising the design and implementation of WEAVE and its data systems, we present the organisation, science drivers and design of a five- to seven-year programme of eight individual surveys to: (i) study our Galaxy's origins by completing Gaia's phase-space information, providing metallicities to its limiting magnitude for \sim3 million stars and detailed abundances for 1.5\sim1.5 million brighter field and open-cluster stars; (ii) survey 0.4\sim0.4 million Galactic-plane OBA stars, young stellar objects and nearby gas to understand the evolution of young stars and their environments; (iii) perform an extensive spectral survey of white dwarfs; (iv) survey 400\sim400 neutral-hydrogen-selected galaxies with the IFUs; (v) study properties and kinematics of stellar populations and ionised gas in z<0.5z<0.5 cluster galaxies; (vi) survey stellar populations and kinematics in 25000\sim25\,000 field galaxies at 0.3z0.70.3\lesssim z \lesssim 0.7; (vii) study the cosmic evolution of accretion and star formation using >1>1 million spectra of LOFAR-selected radio sources; (viii) trace structures using intergalactic/circumgalactic gas at z>2z>2. Finally, we describe the WEAVE Operational Rehearsals using the WEAVE Simulator.Comment: 41 pages, 27 figures, accepted for publication by MNRA
