Authors: Sagherian Knar , Cho Hyeonmi , Steege Linsey M. 
Published: July 2022

AbstractBackgroundResearch has shown sleep problems, elevated fatigue, and high cases of burnout, as well as signs of post‐traumatic stress and psychological distress among nurses during the COVID‐19 pandemic. Many US hospitals attempted to minimise its impact on staff by providing basic resources, mental health services, and wellness programs. Therefore, it is critical to re‐evaluate these well‐being indices and guide future administrative efforts.PurposeTo determine the long‐term impact of the COVID‐19 pandemic after 18 months on hospital nurses' insomnia, fatigue, burnout, post‐traumatic stress, and psychological distress.DesignCross‐sectional.MethodsData were collected online mainly through state board and nursing association listservs between July–September 2021 (N = 2488). The survey had psychometrically tested instruments (Insomnia Severity Index, Occupational Fatigue Exhaustion Recovery Scale, Maslach Burnout Inventory, Short Post‐Traumatic Stress Disorder, and Patient Health Questionnaire‐4) and sections on demographics, health, and work. The STrengthening the Reporting of Observational studies in Epidemiology checklist was followed for reporting.ResultsNurses had subthreshold insomnia, moderate‐to‐high chronic fatigue, high acute fatigue, and low‐to‐moderate intershift recovery. Regarding burnout, they experienced increased emotional exhaustion and personal accomplishment, and some depersonalisation. Nurses had mild psychological distress but scored high on post‐traumatic stress. Nurses who frequently cared for patients with COVID‐19 in the past months scored significantly worse in all measures than their co‐workers. Factors such as nursing experience, shift length, and frequency of rest breaks were significantly related to all well‐being indices.ConclusionNurses' experiences were similar to findings from the early pandemic but with minor improvements in psychological distress. Nurses who frequently provided COVID‐19 patient care, worked ≥12 h per shift, and skipped rest breaks scored worse on almost all well‐being indices.Relevance to clinical practiceAdministration can help nurses' recovery by providing psychological support, mental health services, and treatment options for insomnia, as well as re‐structure current work schedules and ensure that rest breaks are taken.

AbstractAimPolypoid endometriosis is a rare variant of endometriosis and may mimic malignancy. The purpose of this study is to evaluate magnetic resonance (MR) imaging characteristics of polypoid endometriosis for the differential diagnosis with malignancy.MethodsMR imaging findings of four histologically proven polypoid endometriosis were retrospectively evaluated with the review of the literature.ResultsAll polypoid endometriosis exhibited high signal intensity on T2‐weighted images reflecting abundant dilated endometrial glands. Peritoneal lesions were surrounded by low signal intensity rim represented the “black rim sign” reflecting endometriotic fibrous adhesion. Two cases arising from endometriotic cysts showed transmural extension (peritoneal extension and myometrial infiltration). Endometriotic hemorrhagic foci were demonstrated in four lesions as high signal intensity on T1‐weighted images and/or susceptibility‐induced signal voids on susceptibility‐weighted MR sequence. Diffusion‐weighted images showed high signal intensity with relatively high apparent diffusion coefficient (ADC) due to T2 shine‐through effect but no diffusion restriction, and dynamic contrast‐enhanced (DCE) MR imaging showed gradually increasing contrast‐enhancement pattern like benign pathologies.ConclusionsPolypoid endometriosis may mimic malignancy; however, black rim sign may be a characteristic MR imaging finding for the peritoneal lesions, and no diffusion restriction and gradually increasing contrast‐enhancement pattern may reflect its benign nature.

AbstractAimTo explore whether sequential embryo transfer benefits patients with repeated implantation failure (RIF) undergoing frozen–thawed embryo transfer (FET) cycles.MethodsWe included 311 patients with a history of RIF in this retrospective study. We did sequential transfers with a cleavage embryo on day 3 and a blastocyst on day 5 in 77 patients; blastocyst transfers with two blastocysts on day 5 in 80 patients; and cleavage embryo transfers with two cleavage embryos on day 3 in 154 patients. We compared clinical outcomes between the three groups.ResultsThe clinical pregnancy rate was comparable between the blastocyst transfer group (48.8%), the sequential transfer group(48.1%) and the cleavage embryo transfer group (48.1%). There was no statistically significant difference found (p > 0.05). The ongoing pregnancy and multipregnancy rates were also comparable between the three groups (p > 0.05). The early miscarriage rate was significantly higher in the sequential transfer group (32.4%) compared with the blastocyst group (12.8%) and the cleavage embryo group (12.2%) (p < 0.05). However, after adjusting for confounders, there was no significant difference in early miscarriage rates in the sequential transfer group compared with the blastocyst group (odds ratio [OR], 2.97; 95% confidence interval [CI], 0.85–9.24; p = 0.07) and the cleavage embryo group (OR, 3.03; 95% CI, 0.94–8.06; p = 0.08).ConclusionsSequential embryo transfer failed to improve clinical outcomes for patients with RIF.

AbstractAimTo identify the anatomical morphology of levator ani (LA) in primigravidae at term pregnancy and its natural process of changing after delivery.MethodsForty‐one primigravidae (vaginal delivery: 29 women, cesarean delivery in the first stage of labor: 12 women) underwent magnetic resonance imaging (MRI) at full‐term pregnancy, 6 weeks and 10 months postpartum. Three‐dimensional (3‐D) model of LA created from MRI data using Mimics v.21.0 software and source images were assessed to determine the morphology. LA volume (LVOL) was calculated and used as indicator of muscle atrophy.ResultsDecrease of levator hiatus length (LH‐L) was shown in both groups since 6 weeks postpartum. In the vaginal delivery group, the differences in LVOL between time points were significant (p < 0.05), showing a persistent decreasing tendency. Puborectalis attachment width (PAW) on the left was the smallest at 6 weeks postpartum (p < 0.05). LA avulsion and significant 2‐D morphological change after delivery were only observed in this group (p < 0.05); In the cesarean section group, smaller LVOL was found at 6 weeks postpartum comparing with full‐term pregnancy (p < 0.05); Larger levator‐symphysis gap (LSG) and levator hiatus width (LH‐W), smaller PAW were observed in vaginal delivery group comparing with cesarean section group at 6 weeks postpartum (p < 0.05), but none of the values exhibited between‐group differences (p > 0.05) at 10 months postpartum. No other comparisons were considered significant (p >0.05).ConclusionsVaginal delivery, or even active labor itself may both lead to LA atrophy. And the morphology of LA is basically similar in different delivery modes at 10 months postpartum once the onset of labor has occurred, even though it changes more complicatedly after vaginal delivery.
Perceived Organizational Purpose: Systematic Literature Review, Construct Definition, Measurement and Potential Employee Outcomes
Authors: Jasinenko Anna , Steuber Josephina 
Published: July 2022

AbstractOrganizational purpose has recently gained great popularity in research and practice. However, the development of this nascent research field has struggled with definitional ambiguity, the lack of a measurement instrument and little empirical testing of potential outcomes. In our paper, we first introduce and define the multidimensional construct of perceived organizational purpose, which sheds light on the individual and subjective experiences of organizational purpose. Second, building on our construct definition, we develop and validate a four‐dimensional Perceived Organizational Purpose Scale. Third, we disentangle the related yet differentiated concepts of perceived organizational purpose and meaningful work and theorize how substantial knowledge in the field of meaningful work can be transferred to the relatively new and untested field of perceived organizational purpose. Fourth, we critically elaborate and empirically test the relationship of perceived organizational purpose with employee job satisfaction, subjective wellbeing and work‐life conflict.
“That is Giving a Banquet”: Neighbor‐Love as Spiritualization of Romantic Loves in Works of Love
Authors: Hanson Jeffrey 
Published: July 2022

ABSTRACTRecent readings of Kierkegaard's Works of Love have admirably shown how his apparent reservations about romantic love can be deflected on his own terms by imbuing them with some of the moral rigor of neighbor‐love. This paper argues however that these readings must be complemented by the reverse argument, which would show how some of the qualities of romantic loves are in fact preserved in neighbor‐love. By drawing on his dialectics of sensate love, psychical love, spiritual love, and self‐love, I show how Kierkegaard believes neighbor‐love should be impartial and yet exhibit some of the character of preferential romantic loves.

Published: July 2022

ABSTRACTBACKGROUNDPoor dietary habits in childhood can lead to obesity and chronic diseases later in life. Increasing children's nutrition knowledge and liking of fruits and vegetables are key factors in improving diet quality. The purpose of this study was to assess the effects of a nutrition program on knowledge, liking and intake of fruits and vegetables in Montessori students.METHODSClustered‐randomized control trial conducted in a Southeastern US Montessori school. Children aged 4‐6 years old (intervention, n = 22; control, n = 29) participated in a 4‐week nutrition education with taste testing of 12 fruits and vegetables. Nutrition knowledge, fruit and vegetable liking, and intake were measured with questionnaires, and analyzed using repeated measures analysis of covariance and descriptive analyses (SPSS v.23); significance defined as p < 0.05.RESULTSControlling for covariates, significant between group effects for nutrition knowledge (F = 24.16, p < 0.001) and liking tomatoes (F = 7.01, p = 0.01) were found. The intervention group increased vegetable intake (Hedges'g = 1.01) compared to the control, although it was not significant between groups (F = 1.95, p = 0.17).CONCLUSIONSInitial examination of this program indicates that it was effective in increasing knowledge, vegetable liking and intake for young children in the sample. More research is needed to compare outcomes between educational delivery methods.
Explaining the gender gap in negotiation performance: Social network ties outweigh internal barriers

Published: July 2022

AbstractGender disparities in negotiation outcomes contribute to inequality in the workplace and beyond. Explanations of gender gaps in negotiation often focus on internal barriers women face as a consequence of contending with stigma in the workplace and other historically male‐dominated environments, such as stereotype threat and apprehension about negotiating. However, stigma is also associated with relational consequences that may influence success in negotiations. This research compared internal and relational mechanisms for gender disparities in negotiation performance. Seventy‐seven MBA executives reported their apprehension about negotiating, stereotype threat in negotiations, mindset about negotiation‐related stress, and class social networks. Participants were then randomly paired to complete a series of one‐on‐one negotiations based on real‐world scenarios. Overall, men outperformed women in negotiations. Significant gender differences emerged in stereotype threat, stress mindset, and social network centrality. However, only network centrality—specifically number and strength of ties—significantly mediated the relationship between gender and negotiation performance. Position in informal social networks may play an important role in negotiation outcomes, particularly in a shared social environment like the workplace. Although efforts to explain the gender gap in negotiation performance often center internal psychological mechanisms, this research suggests that relational explanations, such as disparities in social networks, merit further attention. Limitations and recommendations for future research and policy are discussed.
The cost of intersectionality: Motherhood, mental health, and the state of the country

Published: July 2022

AbstractThe Coronavirus disease (COVID‐19) pandemic and society's overdue racial awakening (Worland, 2020) have created distinct needs for mothers, especially mothers of Color (MOC) in the United States (US) (Breman et al., 2021; Liu et al., 2021). Prior to the double pandemic (see Addo, 2020), expectations that mothers devote themselves entirely to their children may support increases in mental health symptomology within this population (Rahman et al., 2013). Based on systemic inequities that reside at the foundation of many institutions (e.g., healthcare, law, education) within the US, MOC experience increased worry, anxiety, stress, and fear during the double pandemic (Liu et al., 2021). In addition, MOC engage in mothering practices (e.g., racial socialization) that are unique to raising children who identify as Black, Indigenous, and Persons of Color (BIPOC) (Hughes & Chen et al., 1997). Based on these facts, the authors investigate the sociocultural forces that impact MOC's mental health during the context of the double pandemic through a review of existent literature on this topic. The authors’ analysis and incorporation of intersectionality theory and Black feminist thought uncovers the ways in which these forces may influence the experiences of MOC. Finally, the authors utilize an intersectional‐based policy analysis framework (Hankivsky et al., 2014) to provide recommendations for social policy, education and training, and directions for future research. These recommendations acknowledge the influence of power and privilege in the US while building upon the protective factors that support MOC.

AimTo explore factors influencing fever management practices and antipyretic use among New Zealand Emergency Department (ED) doctors and nurses using the Theoretical Domains Framework (TDF).MethodsCross‐sectional survey of doctors and nurses across 11 New Zealand EDs. The questionnaire examined eight of 12 TDF domains, based on a generic questionnaire validated to assess TDF‐based determinants of health‐care professional behaviour. Relevant domains were identified by the frequency of beliefs; the presence of conflicting beliefs within a domain; and the likely strength of impact of a belief on paediatric fever management in the ED.ResultsAbout 602 participants (243 doctors, 353 nurses and 6 unknown) completed the survey (response rate 47.5%). Over half (351/591, 59.6%, 95% confidence interval (CI) 55.5–63.5%) knew the content of clinical practice guidelines regarding antipyretic use in febrile children (TDF Domain Knowledge), or had been trained to ensure antipyretics are given to febrile children only if they appear distressed (347/592, 58.6%, 95% CI 54.5–62.6%) (Skills). Over 40% (246/590, 95% CI 37.7–45.8%) aim to reduce the fever before discharge (Goals). Most (444/591, 75.1%, 95% CI 71.4–78.6%) participants felt capable of explaining appropriate antipyretic use to parents/care givers (Beliefs about Capabilities). Only a minority (155/584, 26.5%, 95% CI 23.0–30.3%) thought that they can ensure antipyretics are given to febrile children only if they appear distressed when the ED is busy (Environmental Context and Resources).ConclusionsUsing the TDF, we identified factors influencing fever management practices and antipyretic use in the ED. These factors can guide the design of targeted, theory‐informed knowledge translation strategies.

AimTo study the clinical profile and outcomes in children with multisystem inflammatory syndrome in children (MIS‐C).MethodsChildren aged 1 month to 15 years presenting with MIS‐C (May 2020 to November 2021) were enrolled. Clinical, laboratory, echocardiography parameters and outcomes were analysed.ResultsEighty‐one children (median age 60 months (24–100)) were enrolled. Median duration of fever was 5 days (3–7). Twenty‐nine (35.8%) had shock (severe MIS‐C) including 23 (28.3%) requiring inotropes (median duration = 25 h (7.5–33)). Ten required mechanical ventilation, 12 had acute kidney injury and 1 child died. Left ventricular (LV) dysfunction was seen in 38 (46.9%), 16 (19.7%) had coronary artery abnormalities (CAA) and 13 (20%) had macrophage activation syndrome. Sixty‐one (75.3%) were SARS CoV‐2 positive (10 by RT‐PCR and 51 by serology). Sixty‐eight (83.9%) received immunomodulators. Younger age was significantly associated with CAA (P value = 0.05). Older age, LV dysfunction, SARS CoV‐2 positivity, low platelet count and elevated serum ferritin were significantly associated with severe MIS‐C (univariate analysis). Younger age was an independent predictor of CAA (P = 0.05); older age (P = 0.043) and low platelet count (P = 0.032) were independent predictors of severe MIS‐C (multivariate logistic regression analysis).ConclusionOur patients had diverse clinical manifestations with a good outcome. Younger age was significantly associated with CAA. Older age, LV dysfunction, low platelet count and elevated serum ferritin were significantly associated with severe MIS‐C. Younger age is an independent predictor of CAA. Older age and low platelet count are independent predictors of severe MIS‐C.

AimMuscle weakness, fatigue and speech problems can occur in neurofibromatosis type 1 (NF1). The pathogenesis of these symptoms is unclear, likely multifactorial. We examined motor function in limb and speech muscles in NF1 patients.MethodsWe evaluated NF1 and control groups aged 4–18 years for muscle strength, tone and mobility using standard manual testing, joint motion and Beighton score measurements. Speech and language functions were assessed by speech articulation and resonance. As a marker of muscle tissue turnover, we determined collagen degradation products in urine before and after submaximal exercise.ResultsNF1 patients had reduced strength in proximal limb muscles compared to control subjects. Speech articulation problems and hypernasality were more common in NF1 (47% and 38%, respectively). Collagen products excreted in urine correlated with gluteal and biceps muscle strength.ConclusionMuscle dysfunction can be detected in some children with NF1 and may explain certain clinical features including fatigue, speech and articulation problems. If confirmed by further research, these findings may be relevant to the management of this condition.

Published: July 2022

SummaryExcessive daytime sleepiness (EDS) is a hallmark symptom in obstructive sleep apnea (OSA). It is commonly eliminated by obstructive sleep apnea therapy and constitutes a major treatment indication. This study aimed to identify determinants of excessive daytime sleepiness by the Epworth Sleepiness Scale (ESS) scores in the large, representative national obstructive sleep apnea patient cohort of the Swedish Sleep Apnea Registry (SESAR, www.sesar.se). Data from 34,684 patients with obstructive sleep apnea recruited at 23 sites (33% females, mean age 55.7 ± 13.7 years, BMI 30.2 ± 6.3 kg/m2, AHI 29.1 ± 22.3, and ODI 24.9 ± 21.4 events/h) had a mean ESS score in the mild to moderate excessive daytime sleepiness range (9.7 ± 4.9). The proportion of patients with excessive daytime sleepiness was 41.4% in men and 44.6% in women. Independent predictors of excessive daytime sleepiness included gender, age, and hypoxic markers (high ODI and low mean saturation). Univariate and multivariate analyses were used to identify significant predictors for the ESS score and for excessive daytime sleepiness (ESS ≥10) amongst anthropometric factors, sleep apnea frequency (apnea‐hypopnea index (AHI)), markers of intermittent hypoxia (oxygen desaturation index (ODI), mean saturation (mSaO2)), as well as prevalent comorbidities. Depression was associated with higher ESS scores and hypertension/atrial fibrillation with lower scores. The oxygen desaturation index provided a stronger predictor of excessive daytime sleepiness than the apnea‐hypopnea index. The severity of obstructive sleep apnea, captured as the apnea‐hypopnea index, was only weakly associated with daytime sleepiness in this representative obstructive sleep apnea patient cohort. Age had different effects in men and women.The impact of obstructive sleep apnea in a wider patient related perspective needs to be determined after the inclusion of factors other than the apnea‐hypopnea index.
