Published: December 2021

In the present work, an attempt has been made to develop high-performance polymeric hybrid binary blends of epoxy/benzoxazine and benzoxazine/cyanate ester with varying weight percentages (25/75, 50/50 and 75/25 wt%) of resins, namely, bisphenol-F epoxy resin (DGEBF), benzoxazines [bisphenol–F/aniline (BF-a) and imidazole core-based bisphenol/aniline (IBP-a)] and cyanate ester [bisphenol-F bifunctional cyanate ester (BF-CE)]. The molecular structure, polymerisation temperature/cure behaviour, glass transition temperature (Tg) and thermal stability of the neat polymeric matrices and binary hybrid blends of polymeric matrices were characterised using different analytical techniques, viz. Fourier Transform infra-red spectroscopy (FTIR), Nuclear Magnetic Resonance spectroscopy (NMR), Differential Scanning Calorimetry (DSC) and thermogravimetric analysis (TGA). Among the binary hybrid blends, the lowest polymerisation temperatures (Tp) were noticed in the case of blends of epoxy/benzoxazine were 219°C for DGEBF/BF-a (25/75 wt%) and 170°C for DGEBF/IBP-a (25/75 wt%). Similarly, in the case of blends of benzoxazine/cyanate ester, the lowest values of Tp observed were 155°C and 153°C for BF-a/BF-CE (75/25 wt%) and IBP-a/BF-CE (75/25 wt%), respectively. The highest values of Tg observed for the blends of epoxy/benzoxazine were 175°C and 254°C for DGEBF/BF-a (25/75 wt%) and DGEBF/IBP-a (25/75 wt%), respectively. Whereas, the highest values of Tg observed in the case of blends of benzoxazine/cyanate ester were 234°C and 278°C for BF-a/BF-CE (25/75 wt%) and IBP-a/BF-CE (75/25 wt%), respectively. From the TGA results of blends, the maximum degradation temperature (Tmax) and limiting oxygen index (LOI) value calculated from the char yield, which ascertain that almost all the binary hybrid blends of epoxy/benzoxazine and benzoxazine/cyanate ester possess good flame retardant behaviour.
Ethical dilemmas in nursing documentation
Authors: Jørgensen Lone , Kollerup Mette Geil 
Published: December 2021

Background: Nursing documentation is an essential aspect of ethical nursing care. Lack of awareness of ethical dilemmas in nursing documentation may increase the risk of patient harm. Considering this, ethical dilemmas within nursing documentation need to be explored. Aim: To explore ethical dilemmas in nurses’ conversations about nursing documentation. Research design, participants and context: The study used a qualitative design. Participants were registered nurses from a Patient Hotel at a Danish University Hospital. Data were collected in three focus groups with a total of 12 participants. Data analysis consisted of qualitative content analysis inspired by Graneheim and Lundman. Ethical consideration: This study was conducted in accordance with the ethical principles of research and regulations in terms of confidentiality, anonymity and provision of informed consent. Findings: Ethical dilemmas were strongly present in nurses’ conversations about nursing documentation. These dilemmas were demonstrated in two themes: (1) a dilemma between respecting patients’ autonomy and not causing harm, which was visible in nurses’ navigation between written documentation and oral tradition, and (2) a dilemma concerning justice and fair distribution of goods, which was visible in nurses’ balancing between documenting deviations and proof of nursing practice. Discussion: Ethical dilemmas in nursing documentation regarding respecting patients’ autonomy and not causing harm accentuated discussions on professional responsibility and patient participation in clinical decisions. Dilemmas in justice and fair distribution of goods emphasised discussions on trust in relationships versus trust in electronic health records. Conclusion: Actual tendencies in the healthcare system may increase ethical dilemmas in nursing documentation. Sharing otherwise invisible and individual experiences of ethical dilemmas in nursing documentation among nurses, nurse leaders and decision-makers will enable addressing these in reflections and discussions as well as in considering adjustments of conditions for nursing documentation.

Objective: The COVID-19 pandemic may cause a major mental health impact. We aimed to identify demographic or clinical factors associated with psychiatric admissions where COVID-19 was attributed to contribute to mental state, compared to admissions which did not. Methods: A retrospective cohort study was undertaken of inpatients admitted to Northern Psychiatric Unit 1, Northern Hospital in Melbourne, Victoria, Australia during 27/02/2020 to 08/07/2020. Data were extracted for participants who identified COVID-19 as a stressor compared to participants who did not. Fisher’s exact test and Mann-Whitley rank sum test were used. Results: Thirty six of 242 inpatients reported the COVID-19 pandemic contributed to mental ill health and subsequent admission. Reasons given included social isolation, generalized distress about the pandemic, barriers to support services, disruption to daily routine, impact on employment, media coverage, re-traumatization, cancelled ECT sessions, loss of loved ones, and increased drug use during the lockdown. Chronic medical conditions or psychiatric multimorbidity were positively associated and smoking status was negatively associated with reporting the COVID-19 pandemic as a contributor to mental ill health. Conclusion: Screening and identifying vulnerable populations during and after the global disaster is vital for timely and appropriate interventions to reduce the impact of the pandemic worldwide.

Published: December 2021

Train-induced feelable vibrations can bring side effects to people living or working in the building, as well as to operation of precise equipment. As massive construction of over-track buildings above metro depots prevails in megacities, impacts from train-induced feelable vibration take more concern. Four standard-designed 4-story steel-framed offices above the throat area in the Qianhai metro depot in Shenzhen, China, are studied in this research. The field measurements were conducted to investigate the influences of track alignment and track location in the throat area on vibration responses of over-track buildings. Detailed vibration analyses using the finite element method have been conducted. Train-induced floor vibration assessments on human comfort are carried out based on a total of 54 train pass-bys operated in the morning and evening and on different tracks. It can be found that the track alignment primarily affected the higher frequency components of train-induced vibrations, where curved trackinduced vibrations have larger amplitudes. The variance of train-induced building vibrations among pass-bys on different track locations was reduced compared with that of ground vibrations because of the averaging effects caused by multiple transmitting paths within the massive platform and stiff transfer structures. Train-induced acceleration levels at mid-floor can be 20–25 dB larger than those near columns at floor resonance frequencies which are dependent on the structural design. This research gives a comprehensive insight into train-induced vibrations within low-rise steel-framed buildings above the throat area in the metro depot, which is a valuable reference for assessments before the construction of future similar over-track communities.
Maltreatment in Childhood and Perceived Partner Responsiveness in Adult Romantic Relationships: A Dyadic Daily Diary and Longitudinal Study
Authors: Vaillancourt-Morel Marie-Pier , Rosen Natalie O. , Péloquin Katherine , Bergeron Sophie 
Published: December 2021

This study examined the associations between childhood maltreatment (CM) and the mean-level of perceived partner responsiveness (PPR; the extent to which individuals feel cared for, understood, and validated by their partner) over 35 days, the day-to-day variability in PPR, and the initial levels and trajectories of PPR over 1 year in community couples. Both members of 228 couples completed a self-reported measure of CM and provided daily reports of PPR over 35 days and retrospective reports of PPR at three time points over 1 year. A person’s greater CM was related to a lower mean level of PPR over 35 days and to a lower initial level of their own PPR. A person’s sexual abuse, physical neglect, and emotional neglect had an effect over and above other forms of CM in these associations. A person’s greater CM was also related to higher day-to-day variability in their own and their partner’s PPR, and a person’s greater emotional neglect was associated with a sharper decrease over time in their own PPR. These findings provide a more fine-grained understanding of how CM may affect the perceptions of being cared about, accepted, and validated by a partner on a daily basis and over time.

Understanding impact of the coronavirus pandemic (COVID-19) on Adolescents and Young Adults (AYA) with cancer is important to inform care. Online survey of 16–24 year olds receiving cancer treatment at eight cancer centres in the UK. We measured: self-perceived increased anxiety since COVID-19, impact of COVID-19 on treatment, life and relationships, PHQ-8, GAD and the two-item Connor–Davidson Resilience Scale (CD-RISC). 112 AYA participated. 59.8% had previous mental health difficulties. 78.6% reported COVID-19 having a significant impact on life. 79% reported experiencing increased anxiety since COVID-19.43.4% had moderate-severe PHQ-8 scores and 37.1% GADS-7 scores. Impact on life was associated with moderate-severe PHQ-8 scores (OR 5.23, 95% CI 1.65–16.56, p < 0.01), impact on relationships with moderate-severe GADS-7 and PHQ-8 score (OR 2.89, 95% CI 1.11–7.54, p = 0,03; OR 3.54, 95% CI 2.32–15.17, p < 0.01; OR 2.42, 95% CI 1.11–5.25, p =0.03). Greater resilience was associated with lower mod-severe GADS-7and PHQ-8 scores (OR 0.58, 95% CI 0.41–0.81, p < 0.01; OR 0.55 95% CI 0.4–0.72, p < 0.01; OR 0.52, 95% CI 0.38–0.69, p < 0.01). We found high levels of psychological distress. Perceived impact of COVID-19 on relationships and life was predictive of poorer mental health, with resilience a protective factor.
Who gets coached? A qualitative inquiry into community clinicians’ decisions to use caregiver coaching

Published: December 2021

Clinicians’ beliefs about an intervention’s fit with an individual family influence whether they use it with that family. The factors that influence clinicians’ decisions to implement evidence-based practices for young autistic children have yet to be evaluated systematically. These factors may partially account for the significant disparities in quality of and access to early intervention. We examined disparities in clinicians’ reported use of caregiver coaching, an evidence-based practice, with families from minoritized or structurally marginalized groups, and the perceived reasons for those disparities, to assess the factors that influence clinicians’ use of caregiver coaching. We conducted semi-structured interviews with 36 early intervention clinicians from publicly funded early intervention agencies in two distinct geographic regions in the United States. Clinicians identified social and structural factors, including perceived family characteristics and stigma, that influenced their beliefs about the fit of coaching with families from minoritized or structurally marginalized groups. These findings point to the presence of beliefs that likely exacerbate disparities in access to evidence-based practices and reduce the quality of care for minoritized families of young autistic children. These findings highlight the need to develop and deploy equity-focused implementation strategies to improve both access to and quality of evidence-based practices for young autistic children from minoritized groups. Lay abstract Providers’ beliefs about an intervention’s fit with a family can affect whether or not they use that intervention with a family. The factors that affect providers’ decisions to use evidence-based practices for young autistic children have not been studied. These factors may play a role in the major differences we see in the quality of and access to early intervention services in the community. We looked at differences in providers’ use of caregiver coaching, an evidence-based practice, with families from minority or vulnerable backgrounds, and the possible reasons for those differences. We did this to figure out what factors affect providers’ use of caregiver coaching. We interviewed 36 early intervention providers from early intervention agencies in two different parts of the United States. Providers pointed out things like what they thought about a family’s circumstances that affected their beliefs about how well coaching fits with minority and vulnerable families. Our findings bring attention to these beliefs that likely make accessing evidence-based practices for minority and vulnerable families harder and lessen the quality of care for these families of young autistic children. These findings highlight the need to come up with and use strategies to improve both access to and the quality of evidence-based practices for young autistic children from minority and vulnerable groups.
African multilingualism viewed from another angle: Challenging the Casamance exception
Authors: Sagna Serge , Hantgan Abbie 
Published: December 2021

Aims and Objectives/Purpose/Research Questions: The former region of southern Senegal, the Casamance, has been portrayed throughout the literature on African multilingualism in a singular light, for example, as an area where monolingualism does not exist. The purpose of this article is to stress the previously unacknowledged importance of monolingual settings and practices by discussing data that have yet to be presented in the literature. Design/Methodology/Approach: We investigate rural multilingualism and monolingualism across the Casamance by carrying out the following four studies: (a) we conduct a survey of 62 villages with a questionnaire and our newly created ‘blindfold test’, classifying them into two main types; (b) with 34 women we study the role of exogamy in multilingual language acquisition in one of the villages; (c) we analyse child language production data and child directed speech to examine the existence of monolingual language acquisition; (d) we examine the sociolinguistic profiles of 101 speakers of one language community to investigate intergenerational multilingualism. Data and Analysis: Data were analysed using descriptive statistics in the form of frequency counts. Additionally, we couch our results on multilingualism in the theory of canonical typology. Findings/Conclusions: We propose a distinction between multilingual settings, e.g. communities where speakers are most likely to accommodate, and who live among villages largely located on national roads and around cities, and monolingual settings, which constitute most of the villages of the Casamance and where language acquisition is monolingual and where migration, rather than exogamy, accounts for the development of individual multilingualism. Originality: This article contributes unprecedented research methodology for the study of complex multilingual situations such as those found in African multilingual contexts. Significance/Implications: Our study adds to the growing understanding of small-scale multilingualism and the emergence of multilingualism in monolingual contexts.

Published: December 2021

Objectives: Vinyl dimethyl polydimethylsiloxane (VDPDMS) is a urethral bulking agent used for female stress urinary incontinence (SUI), that is clearly visible on computed tomography (CT). Clinical effects are promising, but it remains difficult to identify factors predicting clinical success. Clinical outcome might depend on the shape and position of the implants after injection. Objective of this study is to analyze the appearance and position of bulk material on CT scans and to see whether it is delivered the intended circumferential and mid-urethral position. Methods: A single-center retrospective study was performed in 20 women, treated with VDPDMS for SUI. A senior radiologist analyzed all CTs, using an assessment scheme. This scheme describes whether the bulk is scattered, mid-urethral, and/or circumferentially distributed. The imaging findings were subsequently correlated to the patient global impression of improvement (PGI-I) and the percentage of subjective improvement experienced 6 weeks post-operatively. Results: The patient’s mean age was 61 years, and they underwent median 2.0 previous surgical treatments for SUI. Three patients reported no improvement, 9 patients had 20–90% improvement and 8 reported >90% improvement of their SUI. In 17/74 (24%) positions, the implant was scattered rather than spherical. In 9/20 (45%), the implants were not located in the intended mid-urethral position. In 8/20 patients (40%), the material was distributed circumferentially. Conclusion: This is the first study describing the position and shape of VDPDMS in patients after treatment. The appearance and position of the implants appears to be variable, but optimal positioning or shape seems to be no absolute requisite for success.

Published: December 2021

Background: Maternal obesity and gestational diabetes mellitus (GDM) contribute to increased risk for type 2 diabetes mellitus (T2DM) among both mothers and their offspring. Randomized trials demonstrated T2DM risk reduction in adults following lifestyle behavior change and modest weight loss; the evidence base for at-risk children remains limited. Purpose: Evaluate the feasibility, acceptability, and preliminary efficacy of a T2DM prevention intervention for mother-child dyads delivered by Federally Qualified Health Center staff. Methods: A group randomized design tested the effects of a behavioral lifestyle intervention on T2DM risk factors in women with a history of GDM and their 8- to 12-year-old children. Mother-child dyads were recruited and randomized to intervention or wait-listed control conditions. Intervention participants completed the 13-week intervention; control participants received standard of care. Baseline and 13-week measures assessed program acceptability and feasibility, and explored effects on body weight, waist circumference, hemoglobin A1c, and lifestyle behaviors. Results: Forty-two dyads were randomized and 35 (83%) completed pre-/post-measurements. Participants and program leaders positively rated content and engagement. Nearly all strongly agreed that activities were enjoyable (97%), applicable (96%), useful (97%), and motivational (96%). Attendance averaged 65% across 2 cohorts; delivery costs were approximately $225/dyad. There were no significant differences in body weight, BMI (or BMI z-score), waist circumference, hemoglobin A1c, diet quality, physical activity, sleep, or home environment changes between intervention and control groups. Conclusions: A family T2DM prevention program was feasibly delivered by FQHC staff, and acceptable to mothers and children. Program efficacy will be evaluated in an adequately powered clinical trial.

Published: December 2021

Introduction After surgery for distal femur fractures in elderly patients, weight-bearing is commonly restricted. Immediate non-restrictive weight-bearing might have beneficial effects. There are no randomized studies on the topic. The purpose of this study was to compare the functional outcome between immediate full weight-bearing (FWB) as tolerated and partial weight-bearing (PWB) during the first 8 weeks following plate fixation of distal femur fractures in elderly patients. Methods Patients aged 65 years or older with distal femur fractures of AO/OTA types 33 A2, A3, B1, B2, C1, and C2 were included. Exclusion criteria were impaired cognitive function, concomitant injuries, or inability to follow the postoperative regimen. Internal fixation was achieved with an anatomical lateral distal femur plate applied as a strictly bridge-plating construct. The primary outcome measure was the function index of the short musculoskeletal functional assessment (SMFA) after 52 weeks from injury. Results Thirty-two patients were randomized to FWB (n = 11) or PWB (n = 21). After 16 and 52 weeks, there were no differences in the mean SMFA function index between FWB and PWB (36 vs 43, P = .42 and 52 vs 40, P = .18, respectively) nor in the mean EuroQol 5-dimension index or range of motion (ROM). Overall, the SMFA function index was higher at 52 weeks compared with before injury (44 vs 30, P = .001) as was the mean bothersome index (37 vs 21, P = .011). There was no clear difference in the occurrence of adverse events between the treatment groups. Conclusions There were no differences in functional outcome, adverse events, or ROM between immediate FWB and PWB following plate fixation for a distal femur fracture in elderly patients. A distal femur fracture has a negative effect on the functional status of elderly patients that persists at least up to 1 year following injury.
