Published: July 2021

AbstractYttrium tantalate ceramics with ferroelasticity are potential candidates for thermal barrier coating (TBC) ceramics. During the phase transition process, there are three main phases with monoclinic (I2/a), monoclinic‐prime (P2/a), and tetragonal structures (I41/a), and a comprehensive understanding of their thermophysical properties is required. In this study, the thermal and mechanical properties of polymorphous yttrium tantalate (YTaO4) ceramics are systematically investigated under finite temperature by performing first‐principles calculations combined with quasi‐harmonic approximation. The first‐principle study results show that the volume change from M' to T phase is 12.85 Å3 to 12.95 Å3 per atom, whereas the T to M is 12.95 Å3 to 12.84 Å3 per atom, and the change is less than 1%, showing that this process produces almost no volume change. However, the thermal expansion coefficients (TECs) and Young's modulus vary greatly, the TECs value of M YTaO4 is about 11.13 × 10−6 K−1, which is smaller than T YTaO4 as the value 12.01 × 10−6 K−1, and the Young's modulus values of M, M', and T phases are 140.34, 156.68, and 123.29 GPa, respectively. Lastly, the calculated O–Ta bond is stronger than the O–O and O–Y bonds according to the mean bond population and average bond length, resulting in a higher modulus. This work will not only expand the internal mechanism of the thermophysical properties of YTaO4, but also provides support for the design and application of TBC systems.

AbstractLaser ablation of Ga‐Sb‐Te chalcogenide thin films prepared by radiofrequency magnetron co‐sputtering was monitored with quadrupole ion trap time‐of‐flight mass spectrometry (QIT‐TOF‐MS). The mass spectra of 11 thin films of various compositions (Ga: 0–53.1, Sb: 0–52.0, and Te: 0–100.0 at. %) were recorded. Several series of unary (Gax, Sby, and Tez) binary (GaxSby, GaxTez, and SbyTez), and ternary GaxSbyTez clusters were identified in both positive and negative ion modes. Stoichiometry of observed clusters was determined. Up to 18 binary clusters (positively and negatively charged) were detected for thin film with low Sb content of 6.5 at. %. The highest number (4) of ternary clusters was observed for thin film with high Te content of 66.7 at. %. The number of generated clusters and their peaks intensity varied according to the chemical composition of thin films. Altogether, 41 clusters were detected. The laser ablation monitoring shows laser‐induced fragmentation of thin film structure. The relation of clusters stoichiometries to the chemical composition of thin films is discussed. The fragmentation can be diminished by covering a surface of thin films with paraffin's, glycerol, or trehalose sugar thin layers. The stoichiometry of generated clusters shows partial structural characterization of thin films.

AbstractAimThe aim of this study was to investigate the processes through which personnel understaffing and expertise understaffing jointly shape near misses among nurses during the COVID‐19 pandemic.BackgroundInadequate staffing is a chronic issue within the nursing profession, with the safety consequences of understaffing likely being exacerbated by the COVID‐19 pandemic.DesignThis study used a three‐wave, time‐separated survey design and collected data from 120 nurses in the United States working on the frontline of the pandemic in hospital settings.MethodsParticipants were recruited through convenience sampling in early April 2020. Eligible nurses completed three surveys across a 6‐week period during the COVID‐19 pandemic from mid‐April to the end of May 2020. Study hypotheses were tested with path analyses.Results/FindingsResults reveal that personnel understaffing and expertise understaffing jointly shape near misses, which are known to precede and contribute to accidents and injuries, through different mechanisms. Specifically, personnel understaffing led to greater use of safety workarounds, which only induced near misses when cognitive failures were high. Further, higher levels of cognitive failures appeared to be the result of greater expertise understaffing.ConclusionThis study highlights the importance of addressing issues of understaffing, especially during times of crisis, to better promote nurse and patient safety.ImpactThis study was the first to examine the distinct mechanisms by which two forms of understaffing impact safety outcomes in the form of near misses. Understanding these mechanisms can help leaders and policymakers make informed staffing decisions by considering the safety implications of understaffing issues.
The importance of type species and their correct identification: A key example from tintinnid ciliates (Alveolata, Ciliophora, Spirotricha)

Published: July 2021

AbstractTypes and the corresponding rules in the International Code of Zoological Nomenclature are crucial for taxonomy and are meant to provide nomenclatural stability. In the case of neotypification, especially diligent taxonomic work is required to retain continuity. In the present communication, we first outline the main principles of typification and neotypification. We then discuss a critical case, using a current example from the marine planktonic tintinnid genus Tintinnopsis Stein, 1867 (Alveolata, Ciliophora). This diverse and ubiquitous genus is nonmonophyletic, but its revision and the erection of new related genera is currently prevented by the uncertain affiliation of its type species.

Published: July 2021

AbstractInfidelity is associated with negative effects on couples' relationships, yet some couples are able to overcome these and rebuild their relationship. Few studies have examined this process for couples who stay together after an affair. With a sample of 18 individuals (nine couples), this study explored similarities and differences between injured (i.e., partner who did not have the affair) and involved (i.e., partner who had the affair) partners' experiences across three categories of affair recovery: (a) commitment to the relationship, (b) dimensions of the attachment bond, and (c) healing process. Thematic analysis revealed similarities amongst both partners across categories: (a) frequent and quality communication, (b) mechanisms for rebuilding safety and trust, and (c) the importance of forgiveness. However, partners' experiences varied regarding (a) responses to needs for comfort, (b) their sexual relationship, and (c) responding to reminders. A discussion of these key findings and clinical implications are included.

AbstractMiddle meningeal vessels, dural venous sinuses, and emissary veins leave imprints and canals in the endocranium, and thus provide evidence of vascular patterns in osteological samples. This paper investigates whether craniovascular morphology undergoes changes in craniosynostotic human skulls, and if specific alterations may reflect structural and functional relationships in the cranium. The analyzed osteological sample consists of adult individuals with craniosynostoses generally associated with dolichocephalic or brachycephalic proportions, and a control sample of anatomically normal adult skulls. The pattern and dominance of the middle meningeal artery, the morphology of the confluence of the sinuses, and the size and number of the emissary foramina were evaluated. Craniovascular morphology was more diverse in craniosynostotic skulls than in anatomically normal skulls. The craniosynostotic skulls often displayed enlarged occipito‐marginal sinuses and more numerous emissary foramina. The craniosynostotic skulls associated with more brachycephalic morphology often presented enlarged emissary foramina, while the craniosynostotic skulls associated with dolichocephalic effects frequently displayed more developed posterior branches of the middle meningeal artery. The course and morphology of the middle meningeal vessels, dural venous sinuses, and emissary veins in craniosynostotic skulls can be related to the redistribution of growth forces, higher intracranial pressure, venous hypertension, or thermal constraints. These functional and structural changes are of interest in both anthropology and medicine, involving epigenetic traits that concern the functional and ontogenetic balance between soft and hard tissues.
Building relationships: Is this the answer to effective nutrition policy formulation?

Published: July 2021

AbstractPolicymakers are still struggling to deliver effective nutrition policies, as nutrition policy development can be lost among other competing demands from what is a complex, interconnected food system. Therefore, we explored the relevance of including a wider (relational) marketing perspective to enable effective nutrition policy formulation through in‐depth interviews with food system stakeholders and focus groups with citizens. A relational approach would release the potential to build trust and collaboration, necessary for policy implementation, by focusing on the shared goal of citizen wellbeing. A power shift is needed from large corporations to governments and end‐users (consumers/citizens). For this to happen, governments need to address power sources to orchestrate policy development, rather than merely monitoring the actor set. Acknowledged interdependence that re‐balances power and includes citizens' input in nutrition policy development is vital.

Published: July 2021

AbstractAims and ObjectivesThe aim of the study was to determine the effect of a care programme based on the Comfort Theory on reducing parental anxiety forming during the perioperative process of paediatric day surgery.BackgroundAccording to the Comfort Theory, nurses provide comfort and take precautions related to comfort, and they provide care and assistance by encouraging individuals/families/society and supporting coping methods. This study is the first randomised controlled study to test the effect of a nursing care programme based on the Comfort Theory for paediatric day surgery.DesignRandomised controlled trial.MethodsThe research was completed from June–September 2019 with participation of parents whose children were undergoing paediatric day surgery at a hospital in the Mediterranean region of Turkey. A total of 120 participants were randomly assigned to two equal groups. The intervention group received care programme based on Comfort Theory. The control group received nursing care routinely provided in the clinic. Data were collected using the State‐Trait Anxiety Inventory. Measures were obtained at six points, at baseline, at four interval observations after the initial point and during follow‐up on the 10th postoperative day. The repeated measures ANOVA test and t‐test for independent samples were used to compare the anxiety levels between the intervention and control groups.ResultsThere was a statistically significant difference in favour of the group receiving the care programme based on the Comfort Theory when the anxiety levels between the intervention and control groups were compared.ConclusionsThe care programme based on the Comfort Theory was effective in reducing parental anxiety forming in the perioperative process of paediatric day surgery.Relevance to clinical practiceThe results of this study show the applicability of the care programme for paediatric day surgery. It is recommended that this programme be introduced to nurses in paediatric day surgery.

AbstractAimThe study aimed to explore the risk factors for progression to type 2 diabetes in women with gestational diabetes mellitus and the long‐term impact of gestational diabetes mellitus on the health of their children.BackgroundThe occurrence of gestational diabetes mellitus in women is the strongest predictor of the development of type 2 diabetes in the future.DesignA non‐concurrent cohort and case–control study design and the guidelines for STROBE checklist were used for the study.MethodsWe reviewed medical records for the time period from the archives of the hospitals. The short‐listed women and their children were invited to participate in a ‘Women with gestational diabetes mellitus’ research activity from November 2012–February 2016. Blood tests, physiological indicators and demographic questionnaires were applied for data collection.ResultsA total of 57 women and 57 children participated in the research activity. The risk factors for progression of gestational diabetes mellitus to type 2 diabetes included education level and the 1‐h blood glucose level for the antepartum 100‐g oral glucose tolerance test and the 2‐h blood glucose level for the postpartum 75‐g oral glucose tolerance test. However, these risk factors did not have a significant impact on the body mass index and body fat of the women's children.ConclusionHealthcare providers should adopt a breadth of health education strategies to remind women with gestational diabetes mellitus to be aware of certain risk factors, and to urge them and their children to return for regular follow‐up visits.Relevance to clinical practiceIdentification of the risk factors developing type 2 diabetes can make healthcare units incorporate the postpartum follow‐up of gestational diabetes mellitus into their standard protocol and case managers continue to follow‐up and manage the health of the women and that of their children to reduce adverse health of them.

AbstractObjectivesWe aimed to determine the prevalence of urinary incontinence (UI) during the peri‐ and postpartum period in women from Nanjing, China, and estimate its risk factors.MethodsFrom January to December 2018, a total of 6500 postpartum women were enrolled and asked to complete the questionnaires. Of these, 6370 (98%) women returned the questionnaires with valid responses. Additional data were collected, including age, height, weight, gestation time and parity, and neonatal weight. The International Consultation on Incontinence Questionnaire‐Urinary Incontinence Short Form was used. Surface electromyography (sEMG) and a biofeedback training system were used as a testing platform, and PESEMG values were obtained.ResultsThe prevalence of UI during pregnancy and at 6 weeks postpartum in women was 29.76% and 12.50%, respectively. The prevalence of stress UI (SUI), urge UI (UUI), mixed UI (MUI), and other types of UI that developed during pregnancy was 25.48%, 1.66%, 1.65%, and 0.97%, respectively. The prevalence of SUI, UUI, MUI, and other types of UI at 6 weeks postpartum was 8.49%, 2.07%, 1.16%, and 0.77%, respectively. Multivariate analysis showed that advanced age, greater postpartum body mass index (BMI), macrosomia, multiparity, and vaginal delivery were risk factors of postpartum UI. Women with mild degree of UI in pregnancy, those who had undergone cesarean section, and those without UI before pregnancy were relieved from UI at 6 weeks postpartum.ConclusionsThe rate of UI in peri‐ and postpartum women from Nanjing is consistent across China. The most common type of UI was SUI, with many risk factors affecting its occurrence. Advanced age, greater postpartum BMI, multiparity, macrosomia, and vaginal delivery might be the main risk factors of UI in postpartum women.
Relationships between paternal attitudes, paternal involvement, and infant‐feeding outcomes: Mixed‐methods findings from a global on‐line survey of English‐speaking fathers

AbstractThe breastfeeding intention–behaviour gap remains wide in developed countries. Current studies have focused on maternal attitudes and behaviours concerning infant feeding in order to explore barriers to breastfeeding continuation. There has been limited consideration of the impact of paternal attitudes and behaviours, despite contemporary parenthood evolving and evidence indicating that there are greater levels of paternal involvement in routine childcare tasks. This mixed‐methods study used a triangulation design to examine the associations between paternal attitudes towards parenthood and infant‐feeding methods, levels of paternal involvement, infant‐feeding outcomes, and father–infant relationships. Fathers of infants <52 weeks completed an online survey providing quantitative data (N = 212) and qualitative data (N = 208). For the quantitative data, fathers completed validated measures about their attitude towards parenthood and infant feeding, levels of paternal involvement, and infant‐feeding history. For the qualitative data, questions explored influences on paternal attitudes towards infant feeding and the father–infant relationship. After controlling for covariates, regression analyses found egalitarian attitudes towards parenthood were positively associated with both attitudes towards breastfeeding and levels of paternal involvement. Positive paternal attitudes towards breastfeeding were significantly associated with increased likelihood of breastfeeding. A thematic framework analysis indicated fathers' attitudes towards infant feeding were largely influenced by their families and partners or healthcare professionals. Polarised views were expressed about the impact infant‐feeding methods had on the father–infant relationship, although fathers were united in their desire to bond with their infant. Addressing paternal attitudes and the importance of father–infant involvement in domains other than feeding maybe beneficial in supporting breastfeeding and the father–infant relationship.

Published: July 2021

AbstractAdolescent pregnancy can result in serious risks to the mother and her baby; yet, adolescents are among the least likely to access healthcare. Specific nutrition or antenatal care (ANC) guidelines for supporting pregnant adolescents are not available. To understand experiences and decision‐making of pregnant adolescents in Bangladesh related to ANC and nutrition practices, peer interviewers were trained to conduct qualitative interviews in Dhaka and Rangpur with pregnant adolescents (n = 48), adolescent mothers (n = 48), adolescents' family members (n = 64) and health service providers (n = 32). Key themes explored included perception and support of adolescent pregnancy, experiences in seeking ANC, dietary practices, sources of information and roles of male and female family members. Spheres of influence on adolescent pregnancy were identified through analytical framework informed by the socio‐ecological model. Respondents felt that adolescent pregnancy is risky and that adolescents require support and guidance through this experience. Families were highly influential on the care seeking, health and nutrition of pregnant adolescents, and mothers/mothers‐in‐law primarily took on the decision‐making roles, with husbands actively participating. Adolescents valued family support but felt a loss of autonomy and agency upon becoming pregnant. Financial constraints were the greatest perceived barrier to appropriate nutrition and healthcare; yet, both were valued. There is sometimes discord of health and nutrition beliefs between families and health service providers; more research is needed to understand this further. It is essential to engage family members and adolescents in initiatives to increase access to quality ANC for pregnant adolescents, improve dietary practices and support the ability to delay pregnancy.

AbstractAcute Hemorrhagic Leukoencephalitis (AHLE) is a rare but devastating and fatal form of Acute Disseminated Encephalomyelitis. Very rarely, this can be a complication of vaccination. There is currently no consensus on the optimal treatment strategy of AHLE. We present a rare case of AHLE after seasonal influenza vaccine promptly diagnosed with magnetic resonance imaging (MRI) brain, which showed significant areas of hemorrhage with vasogenic edema including involvement of the pons. The patient was aggressively treated with plasma exchange and corticosteroids and had a favorable outcome.
