Neurodevelopmental outcomes in individuals with fetal alcohol spectrum disorder (FASD) with and without exposure to neglect : clinical cohort data from a national FASD diagnostic clinic

Disentangling the relative developmental impact of prenatal alcohol exposure from postnatal neglect is clinically valuable for informing future service provision. In this study developmental outcomes across groups are compared in a ‘natural experiment’. Methods: Clinical data from 99 persons with fetal alcohol spectrum disorder (FASD) diagnoses were audited. Developmental outcomes (diagnosis of attention deficit hyperactivity disorder, ADHD; social and communication disorder, SCD; or autism spectrum disorder, ASD; Short Sensory Profile, SSP; Vineland II Adaptive Behaviour Scales) were compared across two exposure groups: prenatal alcohol only; and mixed prenatal alcohol and neglect. Results: ADHD (74%) and ASD/SCD (68%) were common, with no significant difference between groups (ADHD, P=0.924; ASD, P=0.742). Vineland age equivalence scores were lower than chronological age (11.1y—prenatal alcohol only—and 12.7y—neglect) across all domains, especially receptive language (3.7y for both groups). Age equivalence did not differ between groups, with the exception of domestic daily living (neglect: 7.7y vs prenatal alcohol only: 5.8y, P=0.027). A probable/definite difference on SSP was more common in the prenatal alcohol only (96% vs 67%, P=0.006). For the individual subscales of SSP, there were no significant differences by neglect category. Discussion: Postnatal neglect in this group did not make the developmental outcome any worse, suggesting that prenatal alcohol influences these outcomes independently. Professionals who support families looking after a child with both FASD and a history of neglect should be aware that the behavioural difficulties are likely to be related to prenatal alcohol exposure and not necessarily reflective of parenting quality

The BaSICS (Baby Skin Integrity Comparison Survey) study : a prospective experimental study using maternal observations to report the effect of baby wipes on the incidence of irritant diaper dermatitis in infants, from birth to eight weeks of age

Background Baby wipes have been shown to be safe and effective in maintaining skin integrity when compared to the use of water alone. However, no previous study has compared different formulations of wipe. The aim of the BaSICS study was to identify any differences in incidence of irritant diaper dermatitis (IDD) in infants assigned to three different brands of wipe, all marketed as suitable for neonates, but which contained varying numbers of ingredients. Methods Women were recruited during the prenatal period. Participants were randomly assigned to receive one of three brands of wipe for use during the first eight weeks following childbirth. All participants received the same nappies. Participants reported their infant’s skin integrity on a scale of 1 to 5 daily using a bespoke smartphone application. Analysis of effect of brand on clinically significant IDD (score 3 or more) incidence was conducted using a negative binomial generalised linear model, controlling for possible confounders at baseline. Analysts were blind to brand of wipe. Results Of 737 women enrolled, 15 were excluded (admitted to neonatal intensive care, premature or other infant health issues). Of the 722 eligible babies, 698 (97%) remained in the study for the full 8-week duration, 24.6% of whom had IDD at some point during the study. Mothers using the brand with the fewest ingredients reported fewer days of clinically significant nappy rash (score≥3) than participants using the two other brands (p=0.002 and p<0.001). Severe IDD (grades 4 and 5) was rare (2.4%). Conclusions Rarity of severe IDD suggested that sensitive formula baby wipes are safe when used in cleansing babies from birth to eight weeks during nappy changes. The brand with fewest ingredients had significantly fewer days of clinically significant IDD. Daily observations recorded on a smartphone application proved to be a highly acceptable method of obtaining real-time data on IDD

The impact of COVID-19 on anaesthesia and critical care services in the UK: a serial service evaluation

Between October 2020 and January 2021, we conducted three national surveys to track anaesthetic, surgical and critical care activity during the second COVID-19 pandemic wave in the UK. We surveyed all NHS hospitals where surgery is undertaken. Response rates, by round, were 64%, 56% and 51%. Despite important regional variations, the surveys showed increasing systemic pressure on anaesthetic and peri-operative services due to the need to support critical care pandemic demands. During Rounds 1 and 2, approximately one in eight anaesthetic staff were not available for anaesthetic work. Approximately one in five operating theatres were closed and activity fell in those that were open. Some mitigation was achieved by relocation of surgical activity to other locations. Approximately one-quarter of all surgical activity was lost, with paediatric and non-cancer surgery most impacted. During January 2021, the system was largely overwhelmed. Almost one-third of anaesthesia staff were unavailable, 42% of operating theatres were closed, national surgical activity reduced to less than half, including reduced cancer and emergency surgery. Redeployed anaesthesia staff increased the critical care workforce by 125%. Three-quarters of critical care units were so expanded that planned surgery could not be safely resumed. At all times, the greatest resource limitation was staff. Due to lower response rates from the most pressed regions and hospitals, these results may underestimate the true impact. These findings have important implications for understanding what has happened during the COVID-19 pandemic, planning recovery and building a system that will better respond to future waves or new epidemics

Experience of sexual self-esteem among men living with HIV

Much of the focus on sexual health for people living with HIV has been on promoting safe sex behaviours. However, also important for sexual health is a positive sexual self-esteem. This article reports on an interpretative phenomenological analysis of interviews with seven men about the impact that having HIV has had on their sense of sexual self. Five overarching themes were identified: the ‘destruction’ of a sexual self; feeling sexually hazardous; sexual inhibition; reclaiming a sexual self and finding a place through sero-sorting. With HIV now being a chronic illness, interventions are required to support people to lead sexually satisfying lives

Bevacizumab for newly diagnosed ovarian cancers: Best candidates among high-risk disease patients (icon-7)

Bevacizumab is approved as a maintenance treatment in first-line setting in advanced-stage III-IV ovarian cancers, because GOG-0218 and ICON-7 phase III trials demonstrated progression-free survival benefits. However, only the subgroup of patients with high-risk diseases (stage IV, and incompletely resected stage III) derived an overall survival (OS) gain in the ICON-7 trial (4.8 months). The modeled CA-125 elimination rate constant K (KELIM) parameter, based on the longitudinal CA- 125 kinetics during the first 100 days of chemotherapy, is a potential indicator of the tumor primary chemo-sensitivity. In the ICON-7 trial dataset, the OS of patients within the low- and high-risk disease groups was assessed according to treatment arms and KELIM. Among the patients with high-risk diseases, those with favorable standardized KELIM of at least 1.0 (n=214, 46.7%) had no survival benefit from bevacizumab, whereas those with unfavorable KELIM less than 1.0 (n=244, 53.2%) derived the highest OS benefit (absolute difference = 9.1 months, 2-sided log-rank P=.10; Cox hazard ratio = 0.78, 95% confidence interval = 0.58 to 1.04, 2-sided P=.09)

Bevacizumab for Newly Diagnosed Ovarian Cancers: Best Candidates Among High-Risk Disease Patients (ICON-7)

Bevacizumab is approved as a maintenance treatment in first-line setting in advanced-stage III-IV ovarian cancers, because GOG-0218 and ICON-7 phase III trials demonstrated progression-free survival benefits. However, only the subgroup of patients with high-risk diseases (stage IV, and incompletely resected stage III) derived an overall survival (OS) gain in the ICON-7 trial (4.8 months). The modeled CA-125 elimination rate constant K (KELIM) parameter, based on the longitudinal CA-125 kinetics during the first 100 days of chemotherapy, is a potential indicator of the tumor primary chemo-sensitivity. In the ICON-7 trial dataset, the OS of patients within the low- and high-risk disease groups was assessed according to treatment arms and KELIM. Among the patients with high-risk diseases, those with favorable standardized KELIM of at least 1.0 (n = 214, 46.7%) had no survival benefit from bevacizumab, whereas those with unfavorable KELIM less than 1.0 (n = 244, 53.2%) derived the highest OS benefit (absolute difference = 9.1 months, 2-sided log-rank P = .10; Cox hazard ratio = 0.78, 95% confidence interval = 0.58 to 1.04, 2-sided P = .09)

Local thermal adaptation and limited gene flow constrain future climate responses of a marine ecosystem engineer.

Rising ocean temperatures and extreme temperature events have precipitated declines and local extinctions in many marine species globally, but patterns of loss are often uneven across species ranges for reasons that are poorly understood. Knowledge of the extent of local adaptation and gene flow may explain such patterns and help predict future trajectories under scenarios of climate change. We test the extent to which local differentiation in thermal tolerance is influenced by gene flow and local adaptation using a widely distributed intertidal seaweed (Hormosira banksii) from temperate Australia. Population surveys across ~2,000 km of the species range revealed strong genetic structuring at regional and local scales (global F ST = 0.243) reflecting extremely limited gene flow, while common garden experiments (14-day exposures to 15, 18, 21°C) revealed strong site differences in early development and mortality in response to elevated temperature. Embryos from many sites spanning a longitudinal thermal gradient showed suppressed development and increased mortality to elevated water temperatures, but populations originating from warmer and more variable thermal environments tended to be less susceptible to warming. Notably, there was significant local-scale variation in the thermal responses of embryos within regions which was corroborated by the finding of small-scale genetic differences. We expect the observed genetic and phenotypic differentiation to lead to uneven responses to warming sea surface temperatures in this important marine foundation species. The study highlights the challenges of predicting species responses to thermal stress and the importance of management strategies that incorporate evolutionary potential for "climate-proofing" marine ecosystems

Two-neutron knockout from neutron-deficient 34^{34}Ar, 30^{30}S, and 26^{26}Si

Two-neutron knockout reactions from nuclei in the proximity of the proton dripline have been studied using intermediate-energy beams of neutron-deficient $^{34}$Ar, $^{30}$S, and $^{26}$Si. The inclusive cross sections, and also the partial cross sections for the population of individual bound final states of the $^{32}$Ar, $^{28}$S and $^{24}$Si knockout residues, have been determined using the combination of particle and $\gamma$-ray spectroscopy. Similar to the two-proton knockout mechanism on the neutron-rich side of the nuclear chart, these two-neutron removal reactions from already neutron-deficient nuclei are also shown to be consistent with a direct reaction mechanism.Comment: Phys.
