Relationships between sensory sensitivity, anxiety and selective eating in children

The present study examines whether parental reports of child selective eating are associated with child anxiety and sensitivity to sensory stimuli in their environment. Parents of 95 children aged 5-10 completed questionnaires about child eating behavior, child anxiety and sensory sensitivity. Results indicated that both anxiety and sensory sensitivity were associated with selective eating. In addition, child sensory sensitivity fully mediated the relationship between anxiety and selective eating in children suggesting that it is greater sensitivity to sensory information which explains why more anxious children are more likely to be selective eaters. Further research is necessary to better understand these relationships and indicate whether gradual exposure interventions with children who are sensory sensitive may help to prevent or reduce selective eating

Acylpeptide hydrolase is a component of the cellular response to DNA damage

Acylpeptide hydrolase (APEH) deacetylates N-alpha-acetylated peptides and selectively degrades oxidized proteins, but the biochemical pathways that are regulated by this protease are unknown. Here, we identify APEH as a component of the cellular response to DNA damage. Although APEH is primarily localised in the cytoplasm, we show that a sub-fraction of this enzyme is sequestered at sites of nuclear damage following UVA irradiation or following oxidative stress. We show that localization of APEH at sites of nuclear damage is mediated by direct interaction with XRCC1, a scaffold protein that accelerates the repair of DNA single-strand breaks. We show that APEH interacts with the amino-terminal domain of XRCC1, and that APEH facilitates both single-strand break repair and cell survival following exposure to H2O2 in human cells. These data identify APEH as a novel proteolytic component of the DNA damage response

Optimised synthesis and further structural diversity of ytterbium benzene-1,4-dicarboxylate MOFs

The optimisation of the crystallisation of the hydrothermally-stable metal–organic framework Yb6-MOF (Yb6(BDC)7(OH)4(H2O)4) to provide a reproducible one-step synthesis is achieved by use of the sodium salt of benzene-1,4-dicarboxylate (Na2BDC) as ligand precursor and control of pH with aqueous NaOH at 190 °C over 3 days. Phase purity is confirmed using powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). During exploration of synthesis conditions from the same set of chemical reagents, three further ytterbium benzene-1,4-dicarboxylates have been isolated and structurally characterised using single-crystal X-ray diffraction, with phase purity assessed by PXRD and TGA. UOW-3 (Yb2(H2O)6(BDC)3) crystallises by lowering pH, and has a relatively dense three-dimensionally connected structure with no Yb–O–Yb linkages but dimers of Yb bridged by BDC linkers lying in the ab plane with a pseudo, pillared-layered structure, where BDC connects along c. UOW-4 (Yb4(BDC)6(H2O)6) forms under the same chemical conditions but upon lowering the temperature to 100 °C, and this material again contains no Yb–O–Yb linkages, but chains of BDC-bridged Yb centres cross-linked to give a dense three-dimensional structure. Upon increasing pH of the synthesis mixture, the material UOW-5 forms, Yb5O(OH)8(BDC)2(HBDC), consisting of dense inorganic layers of ytterbium oxyhydroxide, cross linked by BDC and HBDC pillars. The formulation is supported by infrared spectroscopy, which provides evidence for the HBDC monoanion, and also the presence of a short O–O distance indicative of hydrogen bonding between a carboxylate OH and an oxide anion of the inorganic layer. UOW-3 and UOW-4 both convert to Yb6-MOF upon heating in water above their synthesis temperature, whereas UOW-5 is hydrothermally stable at 240 °C. The structures of the new materials are discussed in terms of ligand binding modes, and connectivity of metal centres, with comparison to other reported Yb-BDC phases in order to relate structural chemistry to their synthesis conditions and the hydrothermal stability of the materials

Parental influences on children's eating behaviour and characteristics of successful parent-focussed interventions

Parental reports suggest that difficulties related to child-feeding and children's eating behaviour are extremely common. While 'fussy eating' does not pose an immediate threat to health, over the long-term, consumption of a poor diet can contribute to the development of a range of otherwise preventable diseases. In addition, the stress and anxiety that can surround difficult mealtimes can have a detrimental impact upon both child and parental psychological wellbeing. Since parents have a great influence over what, when, and how much food is offered, feeding difficulties may be preventable by better parental awareness. The aim of this review is to describe how parental factors contribute to the development of common feeding problems, and to discuss the merits of existing interventions aimed at parents/primary caregivers to improve child-feeding and children's eating behaviour. The potential for different technologies to be harnessed in order to deliver interventions in new ways will also be discussed

Mother, Monster, Mrs, I:A critical evaluation of gendered naming strategies in English sentencing remarks of women who kill

In this article, we take a novel approach to analysing English sentencing remarks in cases of women who kill. We apply computational, quantitative, and qualitative methods from corpus linguistics to analyse recurrent patterns in a collection of English Crown Court sentencing remarks from 2012 to 2015, where a female defendant was convicted of a homicide offence. We detail the ways in which women who kill are referred to by judges in the sentencing remarks, providing frequency information on pronominal, nominative, and categorising naming strategies. In discussion of the various patterns of preference both across and within these categories (e.g. pronoun vs. nomination, title + surname vs. forename + surname), we remark upon the identities constructed through the references provided. In so doing, we: (1) quantify the extent to which members of the judiciary invoke patriarchal values and gender stereotypes within their sentencing remarks to construct female defendants, and (2) identify particular identities and narratives that emerge within sentencing remarks for women who kill. We find that judges refer to women who kill in a number of ways that systematically create dichotomous narratives of degraded victims or dehumanised monsters. We also identify marked absences in naming strategies, notably: physical identification normally associated with narrativization of women’s experiences; and the first person pronoun, reflecting omissions of women’s own voices and narratives of their lived experiences in the courtroom

Rehabilitation versus surgical reconstruction for non-acute anterior cruciate ligament injury (ACL SNNAP): a pragmatic randomised controlled trial

BackgroundAnterior cruciate ligament (ACL) rupture is a common debilitating injury that can cause instability of the knee. We aimed to investigate the best management strategy between reconstructive surgery and non-surgical treatment for patients with a non-acute ACL injury and persistent symptoms of instability.MethodsWe did a pragmatic, multicentre, superiority, randomised controlled trial in 29 secondary care National Health Service orthopaedic units in the UK. Patients with symptomatic knee problems (instability) consistent with an ACL injury were eligible. We excluded patients with meniscal pathology with characteristics that indicate immediate surgery. Patients were randomly assigned (1:1) by computer to either surgery (reconstruction) or rehabilitation (physiotherapy but with subsequent reconstruction permitted if instability persisted after treatment), stratified by site and baseline Knee Injury and Osteoarthritis Outcome Score—4 domain version (KOOS4). This management design represented normal practice. The primary outcome was KOOS4 at 18 months after randomisation. The principal analyses were intention-to-treat based, with KOOS4 results analysed using linear regression. This trial is registered with ISRCTN, ISRCTN10110685, and ClinicalTrials.gov, NCT02980367.FindingsBetween Feb 1, 2017, and April 12, 2020, we recruited 316 patients. 156 (49%) participants were randomly assigned to the surgical reconstruction group and 160 (51%) to the rehabilitation group. Mean KOOS4 at 18 months was 73·0 (SD 18·3) in the surgical group and 64·6 (21·6) in the rehabilitation group. The adjusted mean difference was 7·9 (95% CI 2·5–13·2; p=0·0053) in favour of surgical management. 65 (41%) of 160 patients allocated to rehabilitation underwent subsequent surgery according to protocol within 18 months. 43 (28%) of 156 patients allocated to surgery did not receive their allocated treatment. We found no differences between groups in the proportion of intervention-related complications.InterpretationSurgical reconstruction as a management strategy for patients with non-acute ACL injury with persistent symptoms of instability was clinically superior and more cost-effective in comparison with rehabilitation management

T lymphocytes and their potential role in dementia with Lewy bodies

Dementia with Lewy bodies (DLB) is the second most common neurodegenerative cause of dementia. People with DLB have an inferior prognosis compared to Alzheimer’s disease (AD), but the diseases overlap in their neuropathology and clinical syndrome. It is imperative that we enhance our understanding of the aetiology and pathogenesis of DLB. The impact of peripheral inflammation on the brain in dementia has been increasingly explored in recent years, with T lymphocyte recruitment into brain parenchyma identified in AD and Parkinson’s disease. There is now a growing range of literature emerging on the potential role of innate and adaptive immune cells in DLB, including T lymphocytes. In this review, we examine the profile of T lymphocytes in DLB, focusing on studies of post-mortem brain tissue, cerebrospinal fluid, and the blood compartment. We present an integrated viewpoint on the results of these studies by proposing how changes to the T lymphocyte profile in the brain and periphery may relate to each other. Improving our understanding of T lymphocytes in DLB has the potential to guide the development of disease-modifying treatments
