Organisational challenges to wellbeing in nuclear medicine technologists: Professionalism, burnout and pragmatic growth.

INTRODUCTION: Occupational risk for burnout in nuclear medicine technologists globally, and particularly during disaster demands on the profession, is poorly researched. This idiographic study explored the lived experience of nuclear medicine technologists during COVID-19 in a regional city in Australia. METHODS: Data was collected from five participants using semi-structured interviews and transcribed and analysed according to the protocols of Interpretative Phenomenological Analysis (IPA). RESULTS: Four group experiential themes were identified: Systemic Contraindications, Professional Strengths and Limitations, Pragmatic Growth, and Covid Rollercoaster. For these participants a dichotomous health care system, impacted by COVID-19, risked career longevity and burnout. Through empathic connection with vulnerable patients, they redefined their priorities, re-engaged in supportive connections with colleagues, and sought new pathways. CONCLUSION: Multiple workplace stressors compounded by COVID-19, risked mental wellbeing, in these participants. Nevertheless, these challenges provided opportunities for reflection around career trajectory and longevity precipitating personal growth, job satisfaction and work-life balance. IMPLICATIONS FOR PRACTICE: This study provided a lens on the risk factors inherent for nuclear medicine technologists in Australia, exacerbated by the COVID-19 pandemic. Current, and disaster protective practices, to ensure wellbeing and prevent burnout risk are recommended for future research.

The Importance of Understanding Individual Differences of Emotion Regulation Abilities in 22q11.2 Deletion Syndrome.

Chromosome 22q11.2 deletion syndrome (22q11DS) is characterised by a complex behavioural phenotype including anxiety, attention-deficit/hyperactivity disorder and psychosis. In the current study, we aimed at improving our understanding of the heterogeneity of behavioural characteristics in a group of 129 young people (aged 4-22) with a confirmed 22q11.2 microdeletion and 116 age and gender matched typically developing controls. Half the participants with 22q11DS had behaviour characterised by emotion dysregulation. A cluster analyses, of the participants with 22q11DS, revealed four groups characterised by intact emotion regulation; predominantly internalizing problems; both internalizing and externalizing problems; and predominantly externalizing difficulties. Importantly, it was found that young people with 22q11DS whose emotion dysregulation was characterised by externalizing problems had the poorest levels of functioning. As our understanding of 22q11DS improves, it is becoming increasingly clear that we need a better understanding of how individual differences and psychosocial factors contribute to, and interact with one another, to result in the observable individual differences in the 22q11DS behavioural phenotype.

Correlates of physical activity in children and adolescents with intellectual disabilities: a systematic review.

BACKGROUND: Children and adolescents with intellectual disabilities (ID) participate in low levels of physical activity. To inform the development of interventions, we need to better understand factors associated with physical activity. The aim of this study was therefore to systematically review correlates of physical activity in children and adolescents with ID. METHODS: The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Ovid MEDLINE, Ovid Embase, Web of Science, ERIC, CINAHL and PsycINFO were searched between 1 January 1990 and 29 February 2020 to identify English-language studies, which examined correlates of free-living physical activity in children and adolescents (0-19 years) with ID. Study quality was assessed. Correlates were analysed using a narrative synthesis and classified using the socioecological model as intrapersonal, interpersonal, organisational or environmental. RESULTS: Fifteen studies published between 2010 and 2019 met the inclusion criteria and were included in the review. Forty-eight individual correlates were identified. Studies were predominantly focused on intrapersonal-level correlates. Of those correlates investigated in more than one study (n = 6), having better motor development was positively associated with physical activity. Inconsistent results were found for age and cardiorespiratory fitness. Sex, percentage body fat and body mass index were not correlated. No interpersonal-level, organisational-level or environmental-level correlates were included in more than one study. CONCLUSIONS: To date, we have limited and inconclusive evidence about correlates of physical activity in children and adolescents with ID. Only when future studies unravel correlates and determinants, across all domains of the socioecological model, will the potential opportunities to improve health by increasing physical activity levels be achievable.

Oral health of adults with intellectual disabilities: a systematic review.

BACKGROUND: There have been several past reports that adults with intellectual disabilities experience poor oral health (tooth loss, periodontal health and untreated dental caries). Loss of a functional dentition has serious consequences, including problems with chewing, swallowing, nutrition, speech, temporomandibular joint osteoarthritis and pain and systemic health conditions. Poor oral health is largely preventable through proactive oral care support. In recent years, social care provision for adults has changed, with deinstitutionalisation and home-based personalised care now being the typical provision in high income countries. Hence, oral health inequalities might be reducing. However, there is limited recent evidence-synthesis on the topic. We aimed to address this. METHOD: PROSPERO registration number: CRD42018089880. We conducted a preferred reporting items for systematic reviews and meta-analyses systematic review of publications since 2008. Four databases were searched with a clear search strategy, strict inclusion criteria for selection of papers, double scoring (two raters), systematic data extraction and quality appraisal of included papers. RESULTS: A total of 33/3958 retrieved articles were included, of which 14 were drawn from dental service users and 10 from Special Olympic athletes, therefore not necessarily being representative of the wider population with intellectual disabilities. Despite this limitation, adults with intellectual disabilities were still shown to experience poor oral health. High levels of poor oral hygiene and gingivitis were found, with many also affected by periodontitis and untreated dental decay. There is clear unmet need relating to both periodontal (gum) and tooth health, leading to tooth loss. CONCLUSIONS: Despite reports in the past of poor oral health amongst adults with intellectual disabilities, and despite it being preventable, there remains a high burden of poor oral health. This highlights the need to raise awareness, and for polices on effective daily oral care, and appropriate service provision. The importance of oral health and its possible negative sequelae needs to be elevated amongst carers and professionals.

Zika and travel in the news: a content analysis of US news stories during the outbreak in 2016-2017.

OBJECTIVES: This study aimed to understand what information the US media communicated about Zika virus (ZIKV) and travel in 2016 and 2017. STUDY DESIGN: We conducted a content analysis of news coverage about ZIKV and travel from April 5, 2016 to March 31, 2017. METHODS: We obtained a stratified, random sample of English language, US print newspaper and television news coverage about ZIKV and travel. We developed a coding scheme to assess key messages in the news, including how ZIKV is transmitted, the symptoms and outcomes of ZIKV infection, and recommended prevention behaviors. RESULTS: Almost all news stories mentioned mosquito-borne transmission (96.8%) and just over half mentioned sexual transmission (55.3%). News stories were more likely to talk about ZIKV outcomes (78.8%) than ZIKV symptoms (40.6%). However, outcomes affecting babies were mentioned more frequently than outcomes affecting adults. Recommendations included a wide array of protective behaviors, such as delaying or avoiding travel (77.6%) and using mosquito repellent (41.0%). However, few studies (10.9%) mentioned barriers to practicing ZIKV prevention behaviors. CONCLUSIONS: Public health organizations and professionals can use these findings to help improve communication about future outbreaks of mosquito-borne illnesses. We also recommend conducting real-time monitoring of news media and frequent content analysis of news stories to ensure coverage provides the information the public needs.

Mobile technology use and skills among individuals with fragile X syndrome: implications for healthcare decision making.

BACKGROUND: Little is known about how individuals with fragile X syndrome (FXS) and their families use technology in daily life and what skills individuals with FXS can perform when using mobile technologies. METHODS: Using a mixed-methods design, including an online survey of parents (n = 198) and a skills assessment of individuals with FXS (n = 6), we examined the experiences and abilities of individuals with FXS for engaging with mobile technology. RESULTS: Parents reported that individuals with FXS often used technology in their daily lives, with variations based on age of child, sex, autism status, depression, and overall ability. Parents frequently sought and shared FXS-related information online. Assessment data revealed that individuals with FXS demonstrated proficiency in interacting with technology. CONCLUSIONS: Mobile technology is a tool that can be used in FXS to build skills and increase independence rather than simply for recreational purposes. Implications for using mobile technology to enhance healthcare decision making are discussed.

A population-based, cross-sectional study of the prevalence and correlates of sedentary behaviour of adults with intellectual disabilities.

BACKGROUND: High levels of sedentary behaviour have a negative impact on health and well-being. There is limited evidence on the prevalence and correlates of sedentary behaviour of adults with intellectual disabilities (ID). METHODS: A population-based sample of adults with ID were invited to take part in a comprehensive health check programme. Demographic and health data were collected during a structured interview and physical examination. Screen time was used as a proxy measure of sedentary behaviour. Bivariate and multivariate statistical modelling examined correlates of screen time. RESULTS: Fifty per cent of the 725 participants reported four or more hours of screen time per day. Male gender, higher levels of intellectual ability, mobility problems, obesity, not having hearing impairment and not having epilepsy were all significantly associated with higher screen time in the final multivariate model (R2  = 0.16; Hosmer-Lemeshow goodness of fit statistic P = 0.36). CONCLUSIONS: This is the first study to publish population-based data on the prevalence and correlates of sedentary behaviour in adults with ID. Compared with adults who do not have ID, adults with ID have higher levels, and different correlates, of sedentary behaviour. A better understanding of the social context of sedentary behaviour will inform the design of effective behaviour change programmes for adults with ID.

Cancer-related trauma, stigma and growth: the 'lived' experience of head and neck cancer.

Head and neck cancer is associated with multiple layers of distress including stigma. Stigma attraction or devalued social identity is twofold: (1) it is a cancer associated with lifestyle risk factors and (2) treatment often results in confronting facial disfigurement. Subjective interpretations from nine head and neck cancer patients were analysed using Interpretative Phenomenological Analysis. An overarching superordinate theme--Distress, Stigma and Psychological Growth--encompassed four subordinate themes. Two themes captured the expressed trauma and terror as a result of diagnosis and treatment, and two the redefining of self despite stigma through meaning making. Distress was interpreted as a catalyst for awakening new life interpretations and combined with social support to facilitate two distinct pathways of growth: (1) psychological growth without support; (2) psychological and relational growth with support. Previously unfelt empathetic understanding and altruism for others with cancer emerged from the impact of stigma on 'self'. Acceptance allowed a new sense of identity that recognised cancer-related traumatic distress as integral to growth for these participants. The present study offers a unique insight into cancer-related trauma and stigma and the potential to redefine a more accepting, empathic and altruistic 'self' for psychological growth. Implications are discussed.

Short- and long-term outcomes of every graft recovered during a multi-organ procurement procedure including the intestine.

BACKGROUND: The development of intestinal transplant (Tx) programs introduces thymoglobulin donor treatment as well as an almost complete warm dissection of the abdominal organs to allocate them to different recipients. Our aim is to assess the reproducibility and feasibility of the surgical technique of multi-organ procurement with the use of thymoglobulin donor pre-treatment and report the short- and long-term outcomes of every graft harvested as part of multi-organ procurement (MTOp), including the intestine. METHODS: Data were collected of all organs harvested from MTOp, including the intestines allocated to our center from March 2006 to July 2011. Data from 92 recipients and 116 organs procured from 29 MTOp were analyzed. Twelve hearts, 2 lungs, and 1 cardio-pulmonary block were transplanted; primary graft dysfunction developed in 4 of the 12 hearts and in the cardio-pulmonary block. RESULTS: The survival rate was 75% and 100% for hearts and lungs, respectively. Nineteen livers, 9 kidney-pancreas, 19 kidneys, and 29 intestines were transplanted. Delayed graft function (DGF) of the pancreas developed in 3 of 9 kidney-pancreas, and the other 3 exhibited DGF of the kidney; 4 of 19 Tx kidneys had DGF. The survival was 84%, 78%, 95%, and 65.5% for livers, kidney-pancreas, kidneys, and intestines, respectively. CONCLUSIONS: Organs procured during MTOp including the intestine can be safely used, increasing organ availability and transplant applicability without compromising allocation, quality, and long-term results of the non-intestinal-procured organs.

Extremely marginal liver grafts from deceased donors have outcome similar to ideal grafts.

BACKGROUND: Although there is a worldwide need to expand the donor pool, many cadaveric marginal livers are usually discarded for transplantation. Herein, we report the outcome of a series of patients receiving marginal grafts. METHODS: We analyzed all patients who underwent liver transplantation in our unit from August 2006 to March 2011 (n = 125) with the use of a prospectively collected database. Patients with ≥3 of donor (prolonged hypotensive episodes, donor age >55 years, high vasopressor drug requirement, hypernatremia, prolonged intensive care unit stay, elevated transaminases) and graft-related (cold ischemia >12 hours, warm ischemia time >40 minutes and steatosis >30%) extended criteria were defined as extremely marginal liver grafts (EMLG). The outcomes of patients receiving EMLG were compared with the recipients of grafts without any marginal criteria (ideal grafts). RESULTS: The EMLG group (n = 36) showed higher operative transfusion requirement (66.6% vs 55.6%) as well as 30-day (11.1% vs 55%) and 1-year (22.2% vs 5.5%) mortality rates, compared with the ideal grafts group (n = 18) but without a significant difference. Other variables, such as major complications, postoperative hemodialysis, ICU and hospital stay, and 1-year survival also were not significantly different. CONCLUSIONS: The liver pool can be safely expanded using EMLG from deceased donors for liver transplantation. These usually discarded liver grafts showed similar early and long-term outcomes compared with ideal organs.

Liver transplantation using Chagas-infected donors in uninfected recipients: a single-center experience without prophylactic therapy.

Organ shortage is the first cause of death on liver transplant waiting lists. As a consequence, we recently decided to expand liver acceptance to those organs that could potentially transmit infectious diseases to their recipients. On January 2010, we initiated a prospective protocol using livers from Chagas-infected donors for transplanting uninfected recipients without using prophylactic therapy. During a 13-month period, 9 of 37 (24%) liver transplants were performed within this protocol. After transplant, each recipient was sequentially and strictly monitored for infection transmission using the Strout method and promptly treated with benznidazole if this occurs. During follow-up, two patients died without Chagas infection and only two (donor-derived T. cruzi transmission rate: 2/9; 22%) patients developed donor-derived Chagas transmission without clinical symptoms. The median follow-up time of the seven live patients was 15 months (range: 13-20). At present, all are symptoms-free with excellent allograft function and without evidence of Chagas disease. In conclusion, we consider that Chagas-infected donors are a promising source of liver grafts that could reduce the growing mortality on liver waiting lists in America. Relevant data from larger prospective studies are required to confirm these preliminary excellent results.

Effect of level of farm mechanization early in life on bone later in life.

OBJECTIVE: To determine whether an active rural lifestyle during childhood and adolescence, defined as low farm mechanization, was associated with bone measures later in life. METHODS: DXA bone data from total body, hip and spine, and pQCT data from 4% and 20% distal radius were obtained on 330 individuals (157 women) aged 20-66 years who farmed at least 75% of their lives. Primary bone outcomes included areal bone mineral density (aBMD), aBMD Z-scores, cortical and trabecular volumetric BMD, cortical thickness and periosteal circumference. Relationship between bone and recall of level of farm mechanization as a child was determined after stratifying by sex and controlling for covariates. RESULTS: Controlling for covariates, females from low mechanized farms had higher femoral neck (FN) bone area (p=0.03) than those on high or moderate mechanized farms. No group differences in pQCT ulna measurements or z-scores were found in either gender. CONCLUSION: A low farm mechanization level (high physical activity) prior to 20 years of age is associated with greater FN bone area in females. Future research that includes type and amount of physical activity performed will contribute to growing knowledge of how and when regular physical activity during childhood and adolescence affects adult bone health.

ASPM and microcephalin expression in epithelial ovarian cancer correlates with tumour grade and survival.

BACKGROUND: The clinico-pathological and molecular heterogeneity of epithelial ovarian cancer (EOC) complicates its early diagnosis and successful treatment. Highly aneuploid tumours and the presence of ascitic fluids are hallmarks of EOC. Two microcephaly-associated proteins, abnormal spindle-like microcephaly-associated protein (ASPM) and microcephalin, are involved in mitosis and DNA damage repair. Their expression is deregulated at the RNA level in EOC. Here, ASPM and microcephalin protein expression in primary cultures established from the ascites of patients with EOC was determined and correlated with clinical data to assess their suitability as biomarkers. METHODS: Five established ovarian cancer cell lines, cells derived from two benign ovarian ascites samples and 40 primary cultures of EOC derived from ovarian ascites samples were analysed by protein slot blotting and/or immunofluorescence to determine ASPM and microcephalin protein levels and their cellular localisation. Results were correlated with clinico-pathological data. RESULTS: A statistically significant correlation was identified for ASPM localisation and tumour grade, with high levels of cytoplasmic ASPM correlating with grade 1 tumours. Conversely, cytoplasmic microcephalin was only identified in high-grade tumours. Furthermore, low levels of nuclear microcephalin correlated with reduced patient survival. CONCLUSION: Our results suggest that ASPM and microcephalin have the potential to be biomarkers in ovarian cancer.

Model for end-stage liver disease-based allocation system for liver transplantation in Argentina: does it work outside the United States?

BACKGROUND: In July 2005, Argentina was the first country after the United States to adopt the MELD system. The purpose of the present study was to analyse the impact of this new system on the adult liver waiting list (WL). METHODS: Between 2005 and 2009, 1773 adult patients were listed for liver transplantation: 150 emergencies and 1623 electives. Elective patients were categorized using the MELD system. A prospective database was used to analyse mortality and probability to be transplanted (PTBT) on the WL. RESULTS: The waiting time increased inversely with the MELD score and PTBT positively correlated with MELD score. With scores >/= 18 the PTBT remained over 50%. However, the largest MELD subgroup with <10 points (n = 433) had the lower PTBT (3%). In contrast, patients with T(2) hepatocellular carcinoma benefited excessively with the highest PTBT (84.2%) and the lowest mortality rate (5.4%). The WL mortality increased after MELD adoption (10% vs. 14.8% vs. P < 0.01). Patients with <10 MELD points had >fourfold probability of dying on the WL than PTBT (14.3% vs. 3%; P < 0.0001). CONCLUSIONS: After MELD implementation, WL mortality increased and most patients who died had a low MELD score. A comprehensive revision of the MELD system must be performed to include cultural and socio-economical variables that could affect each country individually.

Successful outcome of severe adenovirus hepatitis of the allograft following liver transplantation.

Here we report the first adult patient who survived severe adenoviral hepatitis of a liver graft, in contrast to 4 previously reported cases in adults, all of which had a fatal outcome. Early diagnosis was based on the immunohistological detection of adenoviral protein in the context of biopsy-proven hepatitis. Dramatic reduction of immunosuppression along with supportive care were the treatment strategies in this case. Adenoviral infection of the allograft should always be considered as a differential diagnosis when clinical signs of severe hepatitis are present after liver transplantation. Accurate diagnosis with immunohistochemical detection of viral proteins in the liver graft is of paramount importance for the early diagnosis and management of this uncommon, severe, and probably underdiagnosed entity.

How useful is PET/CT imaging in the management of post-transplant lymphoproliferative disease after liver transplantation?

Post-transplant lymphoproliferative disease (PTLD) is a serious and potentially life-threatening complication after solid organ transplantation. Here, we report our first experience with the use of PET/CT (positron emission tomography combined with computed tomogram) for the management of patients with PTLD after liver transplantation. Four patients with histologically proven PTLD were analyzed. Conventional work-up included physical examination and head-to-pelvis CT. PET/CT was used in one patient for initial staging and in all patients for follow-up. PET/CT positive findings underwent biopsy. Information provided by PET/CT resulted in a change of medical management in three of the four patients. Conventional work-up missed residual disease after surgery in one and failed to detect a tumor relapse in another patient. However, one patient disclosed a false positive PET/CT finding in the lungs. In conclusion, PET/CT may be a useful tool for staging and therapy monitoring of PTLD after liver transplantation.

[Surgical therapy of liver tumors: resection vs. ablation]. / Chirurgische Therapie von Lebertumoren: Resektion vs. Ablation.

A few years ago surgical resection was the only treatment modality for primary and metastatic liver tumors. However, most of the liver tumors are diagnosed at advanced stage and are unresectable. Criteria for unresectability are: uncontrolled extrahepatic disease, extensive intrahepatic tumor growth, insufficient remnant liver volume and severe co-morbid disease. Several therapeutic strategies have been developed to deal with primarily unresectable tumors. A downstaging ("downsizing") of hepatocellular carcinoma (HCC) can be reached by transarterial chemoembolisation (TACE) or local tumor ablation using ethanol injection, cryosurgery and radiofrequency. Preoperative unilateral portal vein embolization resulting in hypertrophy of the remnant liver volume permits to resect some patients with former unresectable liver tumors. Furthermore, liver transplantation is an option for patients with early stage HCC and liver cirrhosis. Preoperative downstaging of colorectal metastases can be achieved with neoadjuvant chemotherapy, whereas TACE, ethanol injection and liver transplantation are no established options for these patients. So far, there are no standardized guidelines for the treatment of patients with unresectable primary or metastatic liver tumors. In this review we aim to describe the different approaches suggested in the literature and to present our algorithms for the management of patients with liver tumors.

Effects of application methods and plastic covers on distribution of cis- and trans-1,3-dichloropropene and chloropicrin in root zone.

This study examined the effects of three application methods (chisel injection, Avenger coulter injection, and drip irrigation) and two plastic films (polyethylene film [PE] and virtually impermeable film [VIF]) on distribution of cis- and trans- 1,3-dichloropropene (1,3-D) and chloropicrin (CP) in a Florida sandy soil after application of Telone C35 or Telone In-Line. Regardless of application method, VIF retained greater amounts of cis- and trans-1,3-D and CP in the root zone with longer residential time than PE. There was better retention of the three compounds in the root zone when applied with the Avenger coulter injection rig than chisel injection, especially in combination with VIF. Distribution of the three compounds in the root zone was less predictable when applied by drip irrigation. Following drip irrigation, more than 50% of the three compounds in the PE and VIF-covered beds was found near the end of the drip tapes in one experiment, whereas the distribution was much more uniform in the root zone in a second experiment. Among the three biologically active compounds, CP disappeared from the root zone more rapidly than cis- and trans-1,3-D, especially in the PE-covered beds.

Persistence, distribution, and emission of Telone C35 injected into a Florida sandy soil as affected by moisture, organic matter, and plastic film cover.

With the phase-out of methyl bromide scheduled for 2005, alternative fumigants are being sought. This study of Telone C35, a mixture of (Z)- and (E)-1,3-dichloropropene (1,3-D) with chloropicirin (CP), focuses on its emissions, distribution, and persistence in Florida sandy soil in microplots with different soil-water and organic matter carbon (C) content with and without two different plastic film mulches. The addition of CP did not affect the physical behavior of the isomers of 1,3-D. Slower subsurface dispersion and longer residence time of the mixed fumigant occurred at higher water content. An increase in the percent organic carbon in the soil led to a more rapid decrease for chloropicirin than for 1,3-dichloropene isomers. The use of a virtually impermeable film (VIF) for soil cover provided a more even distribution and longer persistence under all the conditions studied in comparison to polyethylene (PE) film cover or no cover. The conditions of near field capacity water content, low organic matter, and a virtually impermeable film cover yielded optimum conditions for the distribution, emission control, and persistence of Telone C35 in a Florida sandy soil.
