ABSTRACT

AIM: To evaluate a community-based psychological health and well-being programme for nurses and midwives. DESIGN: Mixed methods programme evaluation. METHODS: Four studies were included: observational descriptive study (cross-sectional survey) of the health, well-being and experiences of previous programme participants (Study 1); observational exploratory prospective cohort study (longitudinal survey) of health, well-being and experiences of participants who engaged in the programme from 2020 to 2023 (Study 2); qualitative descriptive study (interviews) of experiences and perceptions of nurses and midwives who have engaged with the programme as participants or clinicians (Study 3); observational descriptive study (cross-sectional survey) of experiences and perceptions of programme stakeholders (Study 4). Surveys included validated measures. Data were collected online. Descriptive, repeated measures and thematic analyses were conducted. RESULTS: One-hundred and fifteen participants completed Study 1: 20% (n = 23) reported stress in the severe-to-extremely severe category; 22% (n = 25) reported psychological distress in the moderate-to-severe category. Thirty-one programme participants were followed in Study 2: the effect of the programme on participant well-being over time was not significant. Sixteen programme participants and eight programme clinicians were interviewed (Study 3). Experiences of nurses and midwives engaging with the programme were highly positive and strong attributes of the programme included (1) shared professional experience of clinicians and participants which supported a common language and facilitated understanding, and (2) effective programme leadership, and autonomy and flexibility in the clinicians' role which enabled and supported a positive working experience. Thirty-nine broader stakeholders participated in a cross-sectional survey (Study 4). All stakeholders reported high satisfaction with the programme. Participants considered the programme being 'by nurses and midwives, for nurses and midwives' critical to the programme's success and value. CONCLUSIONS: The community-based psychological health and well-being programme developed, led and delivered by nurses and midwives, for nurses and midwives, was a highly valued resource. IMPACT: Levels of stress and burnout in the health workforce are high. A community-based psychological health and well-being programme for nurses and midwives was found to be an important and highly valued resource for nurses and midwives. A programme delivered by nurses and midwives, for nurses and midwives, was considered critical to programme success. Programme leadership, and autonomy and flexibility in the programme clinicians' roles, facilitated and supported a positive working experience for programme clinicians. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Quality and safety in patient care is directly impacted by the well-being of nurse and midwives. A community-based psychological health and well-being programme for nurses and midwives was found to be an important and highly valued resource for nurses and midwives. REPORTING METHOD: Survey findings were reported according to STROBE (von Elm et al. in Lancet, 370:1453-1457, 2007) and qualitative findings according to COREQ (Tong et al. in International Journal for Quality in Health Care, 19(6):349-357, 2007). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

ABSTRACT

AIM: To determine prevalence, predictors and change over time of nurses' and student nurses' mental health and well-being, and explore nurses' perceptions, barriers and enablers of well-being. DESIGN: Longitudinal mixed-methods survey. METHODS: Forty-nine students and registered nurses participated from Victoria, Australia. Data were collected from December 2019 to July 2020. Validated psychometrics and free-text response questions were employed. Analysis used latent growth curve modelling, Pearson product-moment correlations and thematic analysis. RESULTS: A strong positive correlation was found between self-determination and work well-being, and a strong negative correlation between work well-being and flight risk. Several moderate relationships were found; a moderate positive correlation between work well-being and nurse manager ability, leadership and support, and a moderate negative correlation between burnout and staffing and resource adequacy. Collegial nurse-physician relationships deteriorated. Three themes, physical health, psychological well-being and social connection, were identified as important for nurses' well-being.

ABSTRACT

OBJECTIVE: To identify challenges confronting patients and physiotherapists in managing patellofemoral pain by seeking their perspectives via generative activities involving critique, ideation and formulating shared visions for future treatments. DESIGN: Two Future Workshops, Reflexive Thematic Analysis. METHODS: We recruited 8 patients (median age 36 yrs, 4 women) who were experiencing patellofemoral pain and 10 physiotherapists (54 yrs, 8 women) who treated patients with the condition. Several vignette cases and design cards were constructed and included as tools for facilitating dialogue, throughout all three phases (each ∼40 min duration) of the workshops (i.e., critique, fantasy, implementation). Participants' discussions were audio recorded, transcribed and thematically analyzed independently by four investigators until no additional themes emerged. RESULTS/FINDINGS: Four themes were identified; (i) challenges confronting patients, (ii) learning to manage patellofemoral pain (knowledge), (iii) stakeholder accountability and (iv) development/use of portable applications (apps). Some challenges and strategies were related to family and social networks, financial costs, and psychological factors. Knowledge related to the condition, mental and physical impact of pain, exercises and physical activity. The physiotherapist's role in moderating accurate information was raised, as was that of the GP and personal trainer. Visions of future treatments centered about the inclusion of flexible modes of communication and cultivating mutual accountability. Social determinants and the invisible work of patients in managing their condition was apparent. CONCLUSION: Enacting patient centered care was sought/recommended - requiring consideration of social contexts and flexible delivery. The physiotherapist was seen as a source of accurate information and a point of accountability.

ABSTRACT

BACKGROUND: The wellbeing of individuals influences organisational outcomes. Insight into nurses' wellbeing is crucial to a sustaining a high-quality workforce. AIM: To describe nurses' perceptions and experiences of wellbeing, work wellbeing, and mental health. METHOD: Using a qualitative descriptive design, semi-structured interviews were conducted, transcribed verbatim, analysed inductively and thematically, and reported per consolidated criteria for reporting qualitative research. FINDINGS: Nine Australian nurses were interviewed in 2020, each for 60 to 90 minutes. These nurses had a broad range of clinical roles and years of experience in metropolitan healthcare organisations. Six themes, each related to nurse wellbeing, depicted: (i) value and sense of purpose from nursing, yet also negative consequences of losing sight of oneself within the nursing role; (ii) work nurses did to disengage from their job and create a balance within their life; (iii) significance of the team and senior team as a source of both strength and opportunity for wellbeing; (iv) a range of wellbeing initiatives with a perception these were often developed, and for use, in response to crisis as opposed to preventative or proactive measures; (v) value of additional nurse wellbeing education and promotion of available support; and (vi) novel challenges and ways to wellbeing during times where resources were stretched and usual support systems impacted. DISCUSSION: Identified positive and negative consequences of nursing must be addressed when developing targeted wellbeing interventions. CONCLUSION: New ways of working and supporting individual, team and organisational wellbeing are needed for flourishing working environments. Potential strategies to either leverage or mitigate the positive and negative consequences of nursing are offered.

ABSTRACT

On March 10, 2020, the State of Michigan reported its first case of severe acute respiratory syndrome due to coronavirus disease 2019, which was admitted to Ascension Providence Hospital (APH). Michigan was the third most affected state in March 2020. To address the pandemic, Department of Graduate Medical Education joined the incident command team which consisted of APH leaders (Accreditation Council for Graduate Medical Education Designated Institutional Official, the Chief Medical Officer as commander, Chief Operating Officer, Chief of Logistics, Chief Nursing Officer, representatives from the medical and surgical sections, laboratory, finance, infection control, and occupational health). The team initiated the "crisis capacity surge plan" that was focused on patient care and led mainly by our trainee. In this correspondence we share our successful experience and provide our recommendation on how GME can navigate pandemic crisis.

ABSTRACT

BACKGROUND: The contribution of work to positive mental health is increasingly apparent. Transition into the workplace causes a range of stressors for new graduate nurses who experience both psychological wellbeing and illbeing in their first year of practice. OBJECTIVE: To determine published prevalence, predictors, barriers and enablers of new graduate registered nurse wellbeing, work wellbeing and mental health. DESIGN: Systematic review of quantitative research. DATA SOURCES: Databases included Cumulative Index of Nursing and Allied Health Literature, Excerpta Medica database, Medical Literature Analysis and Retrieval System Online and Psychological Information. Quantitative and mixed-methods studies were considered for inclusion if published in English from 2009 to 2019 reporting primary data analysis including new graduate nurses' wellbeing, work wellbeing and mental health. REVIEW METHODS: Quantitative studies were systematically identified then screened and appraised against pre-determined inclusion criteria. Analysis was conducted by grouping according to analytical methods and results reported as a narrative synthesis. RESULTS: Thirty-four studies were included. The quality of the evidence was variable with just a quarter of the studies being assessed as meeting the quality criteria on all nine measures. For the new graduate nurses prevalence of wellbeing, levels of resilience, optimism, and hope were found to be high. For work wellbeing, most reported higher job satisfaction by 12-months. For work illbeing, levels of burnout were moderately high, predominantly in terms of emotional exhaustion, and stress was initially high, particularly in terms of workload, but decreased over time. For the predictors, job satisfaction was positively predicted by structural empowerment and career satisfaction, and negatively predicted by co-worker incivility, supervisor incivility and emotional exhaustion. For work illbeing, stress was a positive predictor for intent to leave. Stress reductions were associated with momentary levels of high task mastery, social acceptance and role clarity. CONCLUSIONS: For new graduate nurses, levels of emotional exhaustion, workload and stress were moderately high to high initially, decreasing over time as the graduate nurses' job satisfaction increased. Most studies focused on the nurses' intent to resign or stay and both psychological capital and work engagement positively predicted intent to stay whereas work stress positively predicted intent to resign. Resilience and group cohesion moderated the negative effects of some variables, thus may be potential enablers of work wellbeing. The standards of research reporting or design were generally sub-optimal according to quality indicators. Systematic review registration number: (CRD42020148812).

ABSTRACT

AIM: To synthesize Registered Nurses' self-reported perceptions and experiences of psychological well-being and ill-being during their first year of practice. DESIGN: Qualitative meta-synthesis. DATA SOURCES: Databases included Cumulative Index of Nursing and Allied Health Literature, Excerpta Medica database, Medical Literature Analysis and Retrieval System Online and Psychological Information. Qualitative studies were considered for inclusion if published in English, from 2009-2019, reporting primary data analysis including psychological well-being and ill-being experiences of graduate nurses in first year of practice. REVIEW METHODS: Qualitative studies were systematically identified and critically appraised. A meta-synthesis was applied using an open card sort technique to organize empirical data into a matrix of graduate nurses' voices of psychological well-being and ill-being. RESULTS: Twenty-two studies were included. Analysis revealed patterns of positive experiences and emotions. These included feeling valued and part of the team and learning from and feeling supported by other nurses. Negative experiences and emotions such as feeling overwhelmed, stressed, alone and inadequately prepared were also identified. CONCLUSION: Graduate nurses' perceptions and experiences of their psychological well-being and ill-being revealed both positive and negative dimensions during this transition period. Specific examples of strategies that may promote transition nurses' well-being and prevent ill-being were identified such as social connection and support. IMPACT: Increasing the numbers of new nursing graduates world-wide is required to strengthen health systems. Developing strategies to retain these graduates in the workforce is paramount. This review found some graduate nurses experience the transition period as a time of personal growth and fulfilment, for others this period was a stressor. These findings were illustrated in a model of 'ways to well-being'. The potential for knowledge translation of this model extends from graduate nurses as individuals, to nurse entry to practice programs and graduate nurse programs, to organizational policy targeting future health workforce. SYSTEMATIC REVIEW REGISTRATION NUMBER: CRD42020148812.

ABSTRACT

The etiology of idiopathic dilated cardiomyopathy (iDCM) remains unknown. Immune therapies have improved outcome in fetuses with DCM born to mothers with autoimmune disease (aDCM). The purpose of this retrospective study was to compare the myocardial B and T cell profiles in fetuses and neonates with idiopathic DCM (iDCM) versus autoimmune-mediated DCM (aDCM) and to describe the normal cell maturation within the human fetal myocardium. Of 60 fetal autopsy cases identified from institutional databases, 10 had aDCM (18-38 weeks), 12 iDCM (19-37 weeks) and 38 had normal hearts (11-40 weeks). Paraffin-embedded myocardium sections were stained for all lymphocyte (CD45), B cells (CD20, CD79a), T cells (CD3, CD4, CD7, CD8) and monocyte (CD68) surface markers. Two independent, blinded cell counts were performed. Normal hearts expressed all B and T cell markers in a bimodal fashion, with peaks at 22 and 37 weeks of gestation. The aDCM cohort was most distinct from normal hearts, with less overall T cell markers [EST -9.1 (2.6) cells/mm(2), p = 0.001], CD4 [EST -2.0 (0.6), p = 0.001], CD3 [EST -3.9 (1.0), p < 0.001], CD7 [EST -3.0 (1.1), p = 0.01] overall B cell markers [EST -4.9 (1.8), p = 0.01] and CD79a counts [EST -2.3 (0.9), p = 0.01]. The iDCM group had less overall B cell markers [EST -4.0 (1.8), p = 0.03] and CD79a [EST -1.7 (0.9), p = 0.05], but no difference in T cell markers. Autoimmune-mediated DCM fetuses have less B and T cell markers, whereas iDCM fetuses have less B cell markers compared with normal fetal hearts. The fetal immune system may play a role in the normal development of the heart and evolution of dilated cardiomyopathy.

ABSTRACT

BACKGROUND: Hobnail hemangioma is a small benign vascular malformation of the superficial and mid-dermis with variable clinical presentation. OBJECTIVES: To review the clinical characteristics of hobnail hemangioma in pediatric patients. METHODS: A retrospective chart review performed of all histopathologically confirmed cases of hobnail hemangioma from May 2000 to December 2014. Data on demographics, clinical characteristics, and results of immunohistochemical staining were collected. RESULTS: Four male and 2 female patients identified. Congenital lesions were reported in 3 cases. The most common anatomic location was the extremities. Treatment options included observation and surgical excision. CONCLUSIONS: Hobnail hemangioma is an uncommon benign vascular malformation. Due to its benign nature, treatment is not required. If treatment is indicated, complete surgical excision appears to be the most effective option.

ABSTRACT

BACKGROUND: 2,4-Dinitrophenol (DNP) poses serious health-risks to humans. The aims of this three-stage multidisciplinary project were, for the first time, to assess the risks to the general public from fraudulent sale of or adulteration/contamination with DNP; and to investigate motives, reasons and risk-management among DNP-user bodybuilders and avid exercisers. METHODS: Using multiple search-engines and guidance for Internet research, online retailers and bodybuilding forums/blogs were systematically explored for availability of DNP, advice offered on DNP use and user profiles. Ninety-eight pre-workout and weight-loss supplements were purchased and analysed for DNP using liquid-chromatography-mass-spectrometry. Psychosocial variables were captured in an international sample of 35 DNP users (26.06 ± 6.10 years, 94.3 % male) with an anonymous, semi-qualitative self-reported survey. RESULTS: Although an industrial chemical, evidence from the Internet showed that DNP is sold 'as is', in capsules or tablets to suit human consumption, and is used 'uncut'. Analytical results confirmed that DNP is not on the supplement market disguised under fictitious supplement names, but infrequently was present as contaminant in some supplements (14/98) at low concentration (<100mcg/kg). Users make conscious and 'informed' decisions about DNP; are well-prepared for the side-effects and show nonchalant attitude toward self-experimentation with DNP. Steps are often taken to ensure that DNP is genuine. Personal experience with performance- and appearance enhancing substances appears to be a gateway to DNP. Advice on DNP and experiences are shared online. The significant discrepancy between the normative perception and the actual visibility suggests that DNP use is-contrary to the Internet accounts-a highly concealed and lonesome activity in real life. Positive experiences with the expected weight-loss prevail over the negative experiences from side effects (all but two users considered using DNP again) and help with using DNP safely is considered preferable over scare-tactics. CONCLUSION: Legislation banning DNP sale for human consumption protects the general public but DNP is sold 'as is' and used 'uncut' by determined users who are not dissuaded from experimenting with DNP based on health threats. Further research with stakeholders' active participation is imperative for targeted, proactive public health policies and harm-reduction measures for DNP, and other illicit supplements.

ABSTRACT

DNA replication-associated mutations are repaired by two components: polymerase proofreading and mismatch repair. The mutation consequences of disruption to both repair components in humans are not well studied. We sequenced cancer genomes from children with inherited biallelic mismatch repair deficiency (bMMRD). High-grade bMMRD brain tumors exhibited massive numbers of substitution mutations (>250/Mb), which was greater than all childhood and most cancers (>7,000 analyzed). All ultra-hypermutated bMMRD cancers acquired early somatic driver mutations in DNA polymerase ɛ or δ. The ensuing mutation signatures and numbers are unique and diagnostic of childhood germ-line bMMRD (P < 10(-13)). Sequential tumor biopsy analysis revealed that bMMRD/polymerase-mutant cancers rapidly amass an excess of simultaneous mutations (∼600 mutations/cell division), reaching but not exceeding ∼20,000 exonic mutations in <6 months. This implies a threshold compatible with cancer-cell survival. We suggest a new mechanism of cancer progression in which mutations develop in a rapid burst after ablation of replication repair.

ABSTRACT

The pulmonary neuroendocrine cells (PNEC) are located in the epithelial lining of the airways and consist of solitary neuroendocrine cells (NEC) and NEC clusters, the neuroepithelial bodies (NEB). During fetal life, PNEC are the first to differentiate within the primitive airway epithelium, and bombesin expression favors branching of the respiratory tree. We investigated PNEC in Down syndrome (DS), where the lungs often show enlarged and reduced number of alveoli. Immunohistochemistry for bombesin and synaptophysin, PNEC markers, was evaluated in fetal lungs from 15 cases of DS and 11 age-matched controls from the 17th to 23rd week of gestation. Morphometric analysis assessed PNEC in the mucosal lining of each lung, expressed as number/mm. Nonparametric Mann-Whitney U test showed no statistical difference in frequency of PNEC in DS and controls. Our findings suggest that, at least in late second trimester, the distribution and frequency of PNEC in DS fetuses is not altered.

ABSTRACT

BACKGROUND: Fibrosarcoma is a rare tumor in children with limited information on imaging features of these tumors in the literature. OBJECTIVE: To retrospectively review the imaging features of histologically proven congenital infantile fibrosarcoma. MATERIALS AND METHODS: The list of histologically confirmed congenital infantile fibrosarcomas between November 1999 and June 2013 was obtained from the oncology-pathology database. Imaging features and pathology reports of these tumors were reviewed. Patient charts were reviewed and clinical features, management and outcomes were recorded. RESULTS: During the study period, 13 children (9 girls and 4 boys; age range: 0 day-16 months, median age: 2.5 months) with congenital infantile fibrosarcomas were available for complete radiological review. The translocation (t[12;15]) was present in 11/13 (84.6%) and absent in 2/13. Eight/thirteen (61.5%) tumors were located in extremities (5 in lower and 3 in upper), 3/13 in thoracolumbar paraspinal regions, and one each in abdomen and sternocleidomastoid muscle. Imaging features included iso- to hyperintensity on T1-W, hyperintensity on T2-W as compared to skeletal muscles and heterogeneous enhancement. Six (37.5%) tumors showed hemorrhagic components and 2 (15.4%) showed low intensity foci. None of the patients had evidence of regional or distant metastases at diagnosis. Management included surgical resection only (1/13) and combined surgery and chemotherapy (10/13). Overall survival was 100% with a median follow-up of 49.3 months. CONCLUSION: Congenital infantile fibrosarcoma has nonspecific imaging characteristics but should be high on the differential diagnosis in a soft-tissue tumor presenting in infancy, located in an extremity and showing tumoral hemorrhage. Patients have a favorable outcome.

ABSTRACT

BACKGROUND & AIMS: Focal nodular hyperplasia (FNH), a benign liver tumour, has a characteristic appearance on diagnostic imaging (DI) and histology. The role of liver biopsy in children for the diagnosis of FNH is unclear. This study investigates the diagnostic accuracy of DI for FNH in children without comorbidities, compared to liver biopsy. METHODS: A total of 304 consecutive patients (age <18 years) with a biopsied liver mass were retrospectively ascertained (1990-2010). Individuals with a history of malignancy, liver disease or syndromes with increased malignancy risk were excluded. DI and biopsy data were reviewed. RESULTS: After excluding 205 cases, 99 liver masses were studied. Based on histology, the most common diagnosis was hepatoblastoma (46/99, 44%) followed by FNH (23/99, 23%). The mean age at FNH diagnosis was 11.1 ± 5.2 years, with female preponderance (78%), and a median follow-up of 1.35 years (interquartile range 0.54, 4.20 years). 19/23 biopsy-proven FNH met standard criteria for FNH on DI. In 4/23 cases of biopsy-proven FNH, imaging did not suggest FNH. Two false positive cases included adenoma and fibrolamellar hepatocellular carcinoma. On review of original reports, DI had 82.6% sensitivity and 97.4% specificity for the diagnosis of FNH. On blind review, the sensitivity of DI for FNH diagnosis was 81.3% for MRI (13/16), and 53.3% for CT (8/15). CONCLUSIONS: In this cohort of children with liver masses and no comorbidities, a diagnosis of FNH by imaging was highly specific, and MRI was the most sensitive study for its diagnosis. Liver biopsy may be deferred in selected children if the DI, particularly MRI, is indicative of FNH.

ABSTRACT

A dessert matrix previously used for diagnosis of food allergies was incurred with pasteurised egg white or skimmed milk powder at 3, 6, 15 and 30 mg allergen protein per kg of dessert matrix and evaluated as a quality control material for allergen analysis in a multi-laboratory trial. Analysis was performed by immunoassay using five kits each for egg and milk (based on casein) and six 'other' milk kits (five based on ß-lactoglobulin and one total milk). All kits detected allergen protein at the 3 mg kg(-1) level. Based on ISO criteria only one egg kit accurately determined egg protein at 3 mg kg(-1) (p=0.62) and one milk (casein) kit accurately determined milk at 6 (p=0.54) and 15 mg kg(-1) (p=0.83), against the target value. The milk "other" kits performed least well of all the kits assessed, giving the least precise analyses. The incurred dessert material had the characteristics required for a quality control material for allergen analysis.

ABSTRACT

We present two young patients with morphea or localized scleroderma undergoing systemic treatment, who developed papular lesions on pre-existing sclerotic plaques. Histology was compatible with a papular presentation of morphea and other entities in the differential diagnosis were ruled out. We believe this is a very uncommon presentation of activity in lesions of morphea and should be made known to clinicians so that activity and progression of the disease can be recognized and treated to avoid complications.
