Patient navigation across the cancer care continuum: An overview of systematic reviews and emerging literature.

Patient navigation is a strategy for overcoming barriers to reduce disparities and to improve access and outcomes. The aim of this umbrella review was to identify, critically appraise, synthesize, and present the best available evidence to inform policy and planning regarding patient navigation across the cancer continuum. Systematic reviews examining navigation in cancer care were identified in the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Cumulative Index of Nursing and Allied Health (CINAHL), Epistemonikos, and Prospective Register of Systematic Reviews (PROSPERO) databases and in the gray literature from January 1, 2012, to April 19, 2022. Data were screened, extracted, and appraised independently by two authors. The JBI Critical Appraisal Checklist for Systematic Review and Research Syntheses was used for quality appraisal. Emerging literature up to May 25, 2022, was also explored to capture primary research published beyond the coverage of included systematic reviews. Of the 2062 unique records identified, 61 systematic reviews were included. Fifty-four reviews were quantitative or mixed-methods reviews, reporting on the effectiveness of cancer patient navigation, including 12 reviews reporting costs or cost-effectiveness outcomes. Seven qualitative reviews explored navigation needs, barriers, and experiences. In addition, 53 primary studies published since 2021 were included. Patient navigation is effective in improving participation in cancer screening and reducing the time from screening to diagnosis and from diagnosis to treatment initiation. Emerging evidence suggests that patient navigation improves quality of life and patient satisfaction with care in the survivorship phase and reduces hospital readmission in the active treatment and survivorship care phases. Palliative care data were extremely limited. Economic evaluations from the United States suggest the potential cost-effectiveness of navigation in screening programs.

What are the mechanisms underlying the delivery of survivorship care information in Australia? A realist review.

OBJECTIVE: Quality survivorship information is an essential component of cancer care. However, survivors often report not receiving this information and healthcare professionals report limited practical guidance on how to effectively deliver survivorship information. Therefore, this study used realist review methods to identify mechanisms reported within the published literature for communicating survivorship information and to understand the contextual factors that make these mechanisms effective. METHODS: Full-text papers published in CINAHL, PubMed, Web of Science, Scopus, Cochrane Library, and Academic Search Ultimate were included. Studies included in this review were conducted in Australia between January 2006 and December 2023, and reported on how information regarding survivorship care was communicated to adult cancer survivors living in the community. This review utilized realist methodologies: text extracts were converted to if-then statements used to generate context-mechanism-outcome theories. RESULTS: Fifty-one studies were included and six theories for mechanisms that underpin the effective delivery of survivorship information were formed. These include: (1) tailoring information based on the survivors' background, (2) enhancing communication among providers, (3) employing dedicated survivorship staff, (4) providing survivorship training, (5) reducing the burden on survivors to navigate their care, and (6) using multiple modalities to provide information. CONCLUSIONS: Findings can inform practical guidance for how survivorship care information is best delivered in practice. Clinicians can apply this guidance to improve their individual interactions with cancer survivors, as can policymakers to develop healthcare systems and procedures that support effective communication of cancer survivorship information.

What are the post-treatment information needs of rural cancer survivors in Australia? A systematic literature review.

OBJECTIVE: To conduct a systematic literature review to critically assess the met and unmet post-treatment information needs of cancer survivors living in rural communities in Australia, to inform the improvement of survivors' transition from treatment in major cities to community care. METHODS: Cumulative index of nursing and allied health literature, PubMed, Web of Science, Scopus, Cochrane CENTRAL and Academic Search Ultimate databases and websites of 118 cancer organisations were searched for relevant Australian studies published since 2006. Key search terms included 'rural', 'remote', 'regional', 'cancer', 'survivor*', 'living with', and 'post-treatment'. Data reflecting study source, aims, methodology, and reported information needs were extracted and summarised. Study quality was assessed using Joanna Briggs Institute tools. RESULTS: Fifty-two articles met eligibility criteria. Only six of these specified a primary aim of understanding information needs for rural cancer survivors. Information on prognosis and recovery; managing treatment side effects; healthy lifestyle choices; referrals to support services, and face-to-face and written delivery of information at multiple time points were reported as needed and often lacking for rural cancer survivors. CONCLUSIONS: Co-ordinated, multi-step provision of information to support health and recovery after cancer treatment and beyond is likely to be particularly important for rural cancer survivors given their broad range of needs and reduced access to health care services. Findings provide useful recommendations to facilitate patients' transition home to rural communities after cancer treatment in major cities, however, an increased understanding of the information needs of rural survivors is required to inform the development of guidelines that can be used in clinical practice.

Defining research and infrastructure priorities for cancer survivorship in Australia: a modified Delphi study.

PURPOSE: The aim of this study was to establish research and infrastructure priorities for cancer survivorship. METHODS: A two-round modified online Delphi study was completed by Australian experts in cancer survivorship. Initial priorities were generated from the literature and organized into four research categories: physiological outcomes, psychosocial outcomes, population groups, and health services; and one research infrastructure category. In round 1 (R1), panelists ranked the importance of 77 items on a five-point scale (not at all important to very important). In round 2 (R2), panelists ranked their top 5 priorities within each category. Panelists also specified the type of research needed, such as biological, exploratory, intervention development, or implementation, for the items within each research category. RESULTS: Response rates were 76% (63/82) and 82% (68/82) respectively. After R1, 12 items were added, and 16 items combined or reworded. In R2, the highest prioritized research topics and the preferred type of research in each category were: biological research in cancer progression and recurrence; implementation and dissemination research for fear of recurrence; exploratory research for rare cancer types; and implementation research for quality of care topics. Data availability was listed as the most important priority for research infrastructure. CONCLUSIONS: This study has defined priorities that can be used to support coordinated action between researchers, funding bodies, and other key stakeholders. Designing future research which addresses these priorities will expand our ability to meet survivors' diverse needs and lead to improved outcomes.

The quality of life of regional and remote cancer caregivers in Australia.

OBJECTIVE: This study compares the well-being of rural caregivers with that of the general population and explores the potential drivers of poorer outcomes. METHOD: Patient-caregiver dyads (n = 241) residing in regional or remote Queensland, Australia, reported on QoL, chronic illness, caregiver burden, depression, anxiety and stress. Caregiver outcomes were compared with population norms and patient outcomes. Multiple regressions were conducted to identify factors associated with poorer caregiver outcomes. RESULTS: Caregivers reported lower mental health-related QoL (M = 0.436, 95% CI = 0.410-0.462) in comparison with age-matched population norms (M = 0.556, 95% CI = 0.532-0.580). No differences existed between caregiver and population norms for anxiety, stress and depression. Caregiver chronic illness and higher burden were associated with poorer mental and physical QoL, depression, anxiety and stress (η2 s ranging from 0.03 to 0.30). These associations were slightly stronger for male caregivers when compared with female caregivers (η2 s ranging from 0.03 to 0.08). CONCLUSION: It is vital that efforts are made to improve rural caregivers' mental and emotional well-being. Interventions that support caregivers with chronic conditions reduce caregiver burden and take into consideration the unique experience of male caregivers will go some way to addressing this. Future research is needed to identify other drivers of health outcomes in this group.

Is the Australian nursing workforce ready to embrace prescribing under supervision? A cross-sectional survey.

AIM: The aim was to explore nurses' preparedness to expand their practice to prescribe medicines under a supervision model. DESIGN: This was a cross-sectional study. METHODS: A convenience sample of Australian nurses recruited from memberships of State-based Nursing and Midwifery Unions and professional bodies from diverse care settings. Nurses undertook an online researcher-constructed survey between March and July 2021 to identify current prescribing practices, motivations for undertaking education in prescribing and perceived barriers to implementation of nurse prescribing under supervision. Data related to demographics, nursing experience and barriers to becoming a prescriber were analysed descriptively. Logistic regression was used to model nursing experience variables with desire to become a prescriber. RESULTS: A total of 4424 nurses participated with the majority (n = 3645, 82%) reporting they were highly likely to expand their practice to prescribe medicines under supervision. The main motivations to prescribe were to enhance patient care and job satisfaction. Nurses were more likely to want to prescribe if they had <10 years experience (95% CI = 0.3-0.5, p < 0.001), held a bachelor's degree (95% CI = 1.3-2.2, p < 0.001) or higher qualification (95% CI = 1.8-2.9, p < 0.001). Most reported lack of acknowledgement of increased responsibility and workloads (n = 4098, 93%), and insufficient organizational support (n = 4197, 95%) may prevent uptake of nurse prescribing. CONCLUSIONS: Most Australian nurses demonstrated their preparedness to embrace the role of prescribing under supervision. The perceived barriers identified in this study can inform future implementation of this expanded nursing role. IMPACT: The Nursing and Midwifery Board of Australia has proposed a standard of practice to enable nurses to prescribe under supervision. Models of nurse prescribing are being considered globally to address population needs. Successful adoption of this practice is dependent on aspects such as key personnel's acceptance of the initiative. The workforce readiness and barriers highlighted in this study can inform implementation at policy and organizational levels.

Cancer-related help-seeking in cancer survivors living in regional and remote Australia.

OBJECTIVES: To measure rates of detection via screening, perceived self-imposed delays in seeking medical attention, and support seeking in a sample of regional and remote people with a cancer diagnosis and to test whether an association exists between these behaviours and minimising problems and resignation, a need for self-control and reliance and fatalism. Correlations and binary logistic regressions were conducted to test the associations between demographic characteristics, attitudes and behaviours. RESULTS: Females were more likely to have had their cancer detected via screening (OR = 10.02, CI = 3.49-28.78). Younger participants (r = -0.103, p = 0.009) were slightly more likely to seek at least one form of support and online support was sought more often by younger patients (r = -0.269, p < 0.001), females (r = 0.152, p < 0.001), those from higher socio-economic (SES) areas (r = 0.100, p = 0.012), and those with higher education levels (r = 0.247, p < 0.001). Younger (r = -0.161, p < 0.001), and female (r = 0.82, p = 0.013), participants were also slightly more likely to seek support specifically through cancer support groups. No significant relationships between minimising problems and resignation, needs for control and self-reliance or fatalism and detection via screening, support seeking, or perceived self-imposed delays to seeking medical attention were apparent, with the exception that those with higher fatalism (predetermined health) were slightly less likely to report seeking support or information online (OR = 0.79, CI = 0.65-0.95) and slightly more likely to report using Cancer Council's support services (OR = 1.24, CI = 1.02-1.52). CONCLUSIONS: Strategies to improve the accessibility and appropriateness of support available for regional and remote cancer patients should consider interventions that remove barriers to access associated with age, gender, and education as opposed to those which address the attitudinal traits measured here.

Geographic variations in stage at diagnosis and survival for colorectal cancer in Australia: A systematic review.

INTRODUCTION: Australia has one of the highest incidence rates of colorectal cancer (CRC) in the world. Residents in rural areas of Australia experience disadvantage in health care and outcomes. This review investigates whether patients with CRC in rural areas demonstrate poorer survival and more advanced stages of disease at diagnosis. METHODS: Systematic review of peer-reviewed articles and grey literature. Studies were included if they provided data on survival or stage of disease at diagnosis across multiple geographical locations; focused on CRC patients; and were conducted in Australia. RESULTS: Twenty-six articles met inclusion criteria. Twenty-three studies examined survival, while five studies investigated stage at diagnosis. The evidence suggests that non-metropolitan patients are less likely to survive CRC for five years compared to patients living in metropolitan areas, yet there was limited evidence to suggest geographical disparity in stage of diagnosis. CONCLUSIONS: While five-year survival disparities are apparent, these patterns appear to vary as a function of specific region and health jurisdiction, cancer type and year/s of data collection. Future research should examine current data using consistent and robust methods of reporting survival and classifying geographical location. The impact of population-level screening programmes on survival and stage at diagnosis also needs to be thoroughly explored.

Learning from research: Adapting interventions for sexual offending to improve outcomes.

BACKGROUND: Sexual behaviour towards another person who does not or cannot consent to it causes serious harm to its victims. Understandable tendencies towards isolating or shaming the offenders, however, may actually increase risks of recidivism and further such harms. AIM: The study aims to consider evidence for the effectiveness of interventions for sex offenders, mainly in a U.K. context, across four areas: criminal justice system programmes, medication, interventions for sex offenders with personality disorder and a community-based model for the reintegration-Circles of Support and Accountability, and identify key evidence gaps. METHODS: We searched for reviews in the following four strands of work-psychosocial programmes, medication, personality focused therapies, and Circles of Support and Accountability-and identified gaps in knowledge. FINDINGS: Randomised controlled trials in this field are rare but have been achieved. Findings from more naturalistic outcome studies of sex offender treatment programmes are disappointing, but recidivism rates among released sex offender prisoners are low, regardless. Medication relying on substantial physiological change raises substantial ethical concerns. Not all sex offenders have a mental disorder but up to half have been diagnosed with a personality disorder, which may need specific treatment. Evidence is growing that lay work such as Circles of Support and Accountability is a valuable adjunct to other interventions. CONCLUSIONS AND IMPLICATIONS FOR FUTURE RESEARCH: In this field, where tensions between attributions swing between "madness" and "badness," there is growing evidence for optimism that complexity of history and presentation can be met through cooperation between the many disciplines, integrative strategies, and wider community engagement. The need now is for large, prospective controlled trials of interventions, with long periods of follow-up. Perhaps, the most exciting developments have come from the wider public. More research into the qualities of these volunteers might inform public education and health strategies supporting wider safety.

Geographic variation in compliance with Australian colorectal cancer screening programs: the role of attitudinal and cognitive traits.

INTRODUCTION: Colorectal cancer (CRC) patients in regional and rural areas tend to be diagnosed at a more advanced stage than metropolitan patients and have poorer 5-year survival rates. Environmental and cultural factors in non-metropolitan areas often facilitate a more reactive approach to health care, which can result in lower participation in preventative health measures such as screening for early signs of cancer. Individual differences in attitudes and cognitive styles can also act as barriers to cancer screening. Currently, evidence regarding geographical disparity in CRC screening is inconclusive and based largely on test return in nationwide screening programs as opposed to compliance with program guidelines. This study investigates the effect of attitudinal and cognitive traits on compliance with, as opposed to participation in, population CRC screening programs in rural, regional and metropolitan environments. METHODS: A representative cross-section of recipients (n=371, 71% female) of a faecal occult blood test as part of the National Bowel Cancer Screening Program were surveyed in 2017 (mean age = 61.26, standard deviation = 7.05). Participants were asked if they completed and returned the kit or had a valid reason not to (ie prior screening). Postcodes were used to identify participants as metropolitan, regional or rural using the Australian Standard Geographical Classification system. Fatalism, minimisation of problems and resignation (MPR), need for control and self-reliance, and consideration of future consequences (CFC) were measured as traits known to effect health-related help-seeking behaviour. Program compliance rates were compared between rural, regional and metropolitan areas, and logistic regression models with interaction terms were applied to test the differential effects of attitudinal and cognitive factors on program compliance across metropolitan, regional and rural groups. RESULTS: Compliance was significantly lower in regional compared to metropolitan areas (odds ratio (OR)=0.49, 95% confidence interval (CI)=0.29-0.84). Rural status significantly moderated the effect of MPR (OR=0.28, 95%CI=0.11-0.71) and CFC (OR=6.66, 95%CI=1.80-24.63) on compliance and regional status significantly moderated the effect of CFC on compliance (OR=3.41, 95%CI=1.37-8.44). Simple slopes analyses showed that high MPR was associated with lower bowel screening program compliance in rural (OR=0.26, 95%CI=0.11-0.59) and regional (OR=0.60, 95%CI=0.38-0.95) areas, but not in metropolitan areas. High CFC was associated with higher bowel screening program compliance in rural (OR=4.46, 95%CI=1.39-14.47) and regional (OR=2.30, 95%CI=1.19-4.43), but not metropolitan, areas. CONCLUSIONS: Sub-optimal compliance rates are evident in non-metropolitan areas with intervention most needed in regional areas where compliance is lowest, leaving residents at a potentially higher risk of CRCs going undetected. Efforts to increase CRC screening in rural and regional areas should promote the consideration of one's future and discourage attitudes that minimise health issues. This research highlights the way in which individual attitudes and thinking styles may impact preventive health behaviours differently in non-metropolitan communities.

Interventions for prostate cancer survivorship: A systematic review of reviews.

OBJECTIVE: To systematically review the evidence for interventions addressing key domains of the American Cancer Society (ACS) and American Society of Clinical Oncology (ASCO) Prostate Cancer Survivorship Care Guidelines: health promotion, surveillance, physical side effects, psychosocial management, and care coordination. METHODS: We conducted a systematic review of systematic reviews and meta-analyses of interventions targeting ACS/ASCO guideline domains. All titles and abstracts were independently assessed for inclusion based on predetermined criteria. Relevant data were extracted, and assessment of methodological quality was performed. RESULTS: Forty-four systematic reviews of interventions targeting ACS prostate cancer guideline domains were included for review. Exercise and psychosocial interventions were effective for improving men's survivorship outcomes in the domains of health promotion, physical side effects, and psychosocial management. Across the domains, evidence quality varied and there was a limited diversity of participants. No reviews of interventions addressing surveillance and cancer care coordination were identified. CONCLUSIONS: There are substantive knowledge gaps in prostate cancer survivorship research that are a barrier to real improvements in men's outcomes across the breadth of the survivorship experience. A targeted research and implementation agenda in prostate cancer survivorship is urgently needed if we are to meet the current and future burden of this disease on individuals, families, and communities.

Cancer care in regional Australia from the health professional's perspective.

PURPOSE: This study aimed to identify the factors which health professionals believe influence clinical care and outcomes for people with cancer in regional areas of Australia. METHODS: Twelve semi-structured interviews were conducted with a variety of health professionals. Interview questions explored health professional's perspectives on barriers to cancer care for patients, factors which influence clinical care, and access to support in regional areas. Data were interpreted using an inductive thematic analysis approach. RESULTS: Two global themes were identified: rural culture and the health system. Within these global themes, health professionals discussed barriers to cancer care in regional areas, predominantly associated with travel, limited workforce, and poor communication within the health system. Participants also noted many positive aspects of cancer care in regional areas, including more personalised care for the patients and faster career progression for professionals. CONCLUSIONS: Despite several strategies to improve rural cancer care in recent times, including innovative models of care and increased infrastructure, health professionals still perceive many barriers to cancer care in regional Australia. These are predominantly associated with patient demographics, travel difficulties, and inadequate governance. However, there are also many notable benefits to receiving care in regional areas which have been absent from previous literature. These positive factors should be incorporated in efforts to enhance regional cancer care through the recruitment of health professionals to regional areas and development of regional community support networks.

"It's Not Something I Chose You Know": Making Sense of Pedophiles' Sexual Interest in Children and the Impact on Their Psychosexual Identity.

Sexual interest in children is one of the most strongly predictive of the known risk factors for sexual reconviction. It is an important aspect of risk assessment to identify the presence of such interest, and an important task for treatment providers to address such a sexual interest where it is present. It has been argued that understanding pedophiles' deviant sexual interest in children can enhance risk assessment, management, and treatment planning. This research study aims to explore the phenomenology of deviant sexual interest in children, the impact it has on pedophilic offenders' identities, and their views on the treatability of that interest. The study used semistructured interviews and repertory grids to make sense of participants' experiences. The results revealed three superordinate themes: "'living' with a deviant sexual interest," "relational sexual self," and "possible and feared sexual self." The analysis unpacks these themes and repertory grid analysis is used to explore a subset of participants' identities in more detail. The results reveal that there needs to be an acceptance from both client and therapist that their sexual interest in children may never go away. Through this acceptance, clients could work on enhancing sexual self-regulation, recognizing their triggers, and so managing their sexual thoughts, feelings, and behavior. Implications for treatment are also discussed.

A systematic review of geographical differences in management and outcomes for colorectal cancer in Australia.

BACKGROUND: Australia and New Zealand have the highest incidence of colorectal cancer (CRC) in the world, presenting considerable health, economic, and societal burden. Over a third of the Australian population live in regional areas and research has shown they experience a range of health disadvantages that result in a higher disease burden and lower life expectancy. The extent to which geographical disparities exist in CRC management and outcomes has not been systematically explored. The present review aims to identify the nature of geographical disparities in CRC survival, clinical management, and psychosocial outcomes. METHODS: The review followed PRISMA guidelines and searches were undertaken using seven databases covering articles between 1 January 1990 and 20 April 2016 in an Australian setting. Inclusion criteria stipulated studies had to be peer-reviewed, in English, reporting data from Australia on CRC patients and relevant to one of fourteen questions examining geographical variations in a) survival outcomes, b) patient and cancer characteristics, c) diagnostic and treatment characteristics and d) psychosocial and quality of life outcomes. RESULTS: Thirty-eight quantitative, two qualitative, and three mixed-methods studies met review criteria. Twenty-seven studies were of high quality, sixteen studies were of moderate quality, and no studies were found to be low quality. Individuals with CRC living in regional, rural, and remote areas of Australia showed poorer survival and experienced less optimal clinical management. However, this effect is likely moderated by a range of other factors (e.g., SES, age, gender) and did appear to vary linearly with increasing distance from metropolitan centres. No studies examined differences in use of stoma, or support with stomas, by geographic location. CONCLUSIONS: Overall, despite evidence of disparity in CRC survival and clinical management across geographic locations, the evidence was limited and at times inconsistent. Further, access to treatment and services may not be the main driver of disparities, with individual patient characteristics and type of region also playing an important role. A better understanding of factors driving ongoing and significant geographical disparities in cancer related outcomes is required to inform the development of effective interventions to improve the health and welfare of regional Australians.

Bell's Palsy in Children (BellPIC): protocol for a multicentre, placebo-controlled randomized trial.

BACKGROUND: Bell's palsy or acute idiopathic lower motor neurone facial paralysis is characterized by sudden onset paralysis or weakness of the muscles to one side of the face controlled by the facial nerve. While there is high level evidence in adults demonstrating an improvement in the rate of complete recovery of facial nerve function when treated with steroids compared with placebo, similar high level studies on the use of steroids in Bell's palsy in children are not available. The aim of this study is to assess the utility of steroids in Bell's palsy in children in a randomised placebo-controlled trial. METHODS/DESIGN: We are conducting a randomised, triple-blinded, placebo controlled trial of the use of prednisolone to improve recovery from Bell's palsy at 1 month. Study sites are 10 hospitals within the Australian and New Zealand PREDICT (Paediatric Research in Emergency Departments International Collaborative) research network. 540 participants will be enrolled. To be eligible patients need to be aged 6 months to < 18 years and present within 72 hours of onset of clinician diagnosed Bell's palsy to one of the participating hospital emergency departments. Patients will be excluded in case of current use of or contraindications to steroids or if there is an alternative diagnosis. Participants will receive either prednisolone 1 mg/kg/day to a maximum of 50 mg/day or taste matched placebo for 10 days. The primary outcome is complete recovery by House-Brackmann scale at 1 month. Secondary outcomes include assessment of recovery using the Sunnybrook scale, the emotional and functional wellbeing of the participants using the Pediatric Quality of Life Inventory and Child Health Utility 9D Scale, pain using Faces Pain Scale Revised or visual analogue scales, synkinesis using a synkinesis assessment questionnaire and health utilisation costs at 1, 3 and 6 months. Participants will be tracked to 12 months if not recovered earlier. Data analysis will be by intention to treat with primary outcome presented as differences in proportions and an odds ratio adjusted for site and age. DISCUSSION: This large multicenter randomised trial will allow the definitive assessment of the efficacy of prednisolone compared with placebo in the treatment of Bell's palsy in children. TRIAL REGISTRATION: The study is registered with the Australian New Zealand Clinical Trials Registry ACTRN12615000563561 (1 June 2015).

Thyroid dysfunction in preterm neonates exposed to iodine.

BACKGROUND: Infants <32 weeks' gestation should not be exposed to topical iodine and its avoidance is recommended during pregnancy and breast feeding. Exposure to contrast media and topical iodine is frequently used in many preterm neonates. AIM: To determine whether thyrotropin levels in preterm infants are affected by exposure to intrapartum/neonatal topical iodine and/or the use of iodinated contrast media. DESIGN: Infants <32 weeks' gestation were recruited. Maternal and neonatal exposures to iodinated contrast media and topical iodine were recorded; levels of thyrotropin and thyroxine were measured from blood-spot cards on postnatal days 7, 14, 28 and the equivalent of 36 weeks' gestation. RESULTS: One hundred and twenty-five infants were exposed to topical iodine/contrast media and 48 infants were unexposed. No infants were treated for hypothyroidism; three infants (exposed group) had transient hyperthyrotropinaemia. Mean thyrotropin levels were significantly higher on postnatal days 7, 14 and 28 in infants exposed to topical iodine prior to caesarean section compared to unexposed infants, a relationship which persisted after adjustment. CONCLUSIONS: In the context of this study, neonatal thyroid dysfunction was seen following exposure to iodine via caesarean section but not via exposure to contrast media.

Do research studies in the UK reporting child neurodevelopment adjust for the variability of assessors: a systematic review.

AIM: Neurodevelopment is a key outcome for many childhood trials and observational studies. Clinically important decisions may rest on finding relatively small differences in neurodevelopment between groups receiving complex and costly interventions. Our purpose was to determine whether studies which measure neurodevelopment report the numbers, training, and auditing of assessors and, for multiple assessor studies, whether the results were adjusted and if so by which method? METHOD: Electronic searches were conducted using Medline, Embase, Cinahl, PsycINFO, and the Cochrane Library. A study was eligible if it reported neurodevelopmental outcome in children resident in the UK, less than or equal to 18 years and was published between 2000 and 2015. Trials and observational studies were included. RESULTS: Three hundred and seven full papers were reviewed: 52% of papers did not report the number of assessors used; 21% used a single assessor; and 27% used multiple assessors. Thirty-five per cent mentioned that assessors were trained in the use of the neurodevelopmental tool; 13% of assessors were audited; and only 1% of studies adjusted statistically for the number of assessors. INTERPRETATION: At the very least, the quality of reporting the use of assessors in these research publications is poor, while at worst, the variability of assessors may mask the true relationship between an intervention/observation and neurodevelopmental outcome.

Arterio-venous differences in cord levels of catecholamines, glucose, lactate and blood gases.

BACKGROUND: Norepinephrine (NE) and epinephrine (EPI) levels are higher in cord arterial blood relative to venous blood, consistent with active mechanisms of placental-maternal clearance. There are no contemporary studies of cord arteriovenous blood levels of sulfated and non-sulfated catechols. AIM: To assess the arteriovenous differences in cord blood levels of dopamine (DA), the sulfated catecholamines and their sulfated and non-sulfated metabolites. To correlate levels of oxygen, H+/CO2, and glucose with cord catecholamine levels. METHODS: Fifty-seven term infants, delivered by elective cesarean section, were recruited. Cord arterial and venous blood was sampled; levels of glucose, lactate, blood gases, six catechols and their sulfated conjugates were measured. RESULTS: With one exception (DOPA sulfate), mean cord arterial levels of sulfated and non-sulfated catechols were significantly higher than venous levels. Arterial lactate and glucose levels were independently associated with NE levels, but only lactate was associated with levels of EPI and DA. CONCLUSION: This study establishes that in vivo metabolic parameters of hypoxia, respiratory and metabolic acidosis are associated with catecholamine levels, a key relationship for perinatal adaptation and homeostasis, and findings that are consistent with in vitro studies of the regulators of catecholamine secretion.

A circle of silence: The attitudes of patients older than 65 years of age to ceasing long-term sleeping tablets.

BACKGROUND: Nocturnal benzodiazepines have a significant negative health impact on the elderly, yet they continue to be used. OBJECTIVE: The aim of this study was to assess elderly patients' use and knowledge of nocturnal benzodiazepines, and their attitudes to cessation. METHODS: Semi-structured telephone interviews were conducted with elderly patients (n = 17) from four general practices in Australia. RESULTS: Our study found that the initiation of benzodiazepine use was often at a time of stress for the patient. Long-term use was not in-tended, and patients conveyed poor awareness of the side effects and addictive potential of benzodiazepines. Patients' perceived attitudes of their general practitioner (GP) to prescribing benzodiazepines and lack of awareness of alternative therapies were key to continuation. Confounding factors such as pain often contributed to sleep disturbance. Many patients expressed a willingness to cease nocturnal benzodiazepine use. DISCUSSION: These data assist in raising GPs' awareness of patients' attitudes to cessation of nocturnal benzodiazepine use. More time spent with patients presenting for repeat prescriptions, explaining side effects, discussing alternative options and investigating reasons for not sleeping could reduce benzodiazepine use among the elderly.
