The value of a breast care nurse in supporting rural and remote cancer patients in Queensland

The role of the Breast Care Nurse in Queensland's Supporting Rural Women with Breast Cancer Project was evaluated by mixed methodology. Through questionnaire and interview patients provided views about the nurse's role under categories of Awareness, Access, Coordination, Information and Psychosocial, Emotional and Practical support. Of the 51 participants 37 resided in rural and remote areas with 18 living between 100 and 500 miles from specialised breast care services. The BCN met with patients at their regular hospital visits and was available by telephone at any time. There was overwhelming agreement among the participants that the timing of contact, ease of accessibility, information provided and support offered were extremely valuable in making their treatment and recovery easier. The vast majority of participants would recommend hospitals with a BCN to their friends. Members of the multidisciplinary care team provided views on Awareness of the BCN, Influence on Care Management, Communication and Patient Outcomes. They recognised the benefits of the BCN to patients and to coordination and liaison of the team. The findings concur with unpublished Australian reports that demonstrate the success of dedicated Breast Care Nurses. The BCN model of care could be used successfully to support other medical conditions

Fate of global superconductivity in arrays of long SNS junctions

Normal-metal films overlaid with arrays of superconducting islands undergo Berezinskii-Kosterlitz-Thouless (BKT) superconducting transitions at a temperature $T_{BKT}$. We present measurements of T$_{BKT}$ for arrays of mesoscopic Nb islands patterned on Au films for a range of island spacings $d$. We show that $T_{BKT} \sim 1/d^2$, and explain this dependence in terms of the quasiclassical prediction that the Thouless energy, rather than the superconducting gap, governs the inter-island coupling. We also find two deviations from the quasiclassical theory: (i) $T_{BKT}$ is sensitive to island height, because the islands are mesoscopic; and (ii) for widely spaced islands the transition appears to lead, not to a superconducting state, but to a finite-resistance "metallic" one.Comment: 12 pages, 4 figure

Building health: an epidemiological study of "sick building syndrome" in the Whitehall II study

Objectives: Sick building syndrome (SBS) is described as a group of symptoms attributed to the physical environment of specific buildings. Isolating particular environmental features responsible for the symptoms has proved difficult. This study explores the role and significance of the physical and psychosocial work environment in explaining SBS. Methods: Cross sectional data on the physical environment of a selection of buildings were added to individual data from the Whitehall II study—an ongoing health survey of office based civil servants. A self-report questionnaire was used to capture 10 symptoms of the SBS and psychosocial work stress. In total, 4052 participants aged 42–62 years working in 44 buildings were included in this study. Results: No significant relation was found between most aspects of the physical work environment and symptom prevalence, adjusted for age, sex, and employment grade. Positive (non-significant) relations were found only with airborne bacteria, inhalable dust, dry bulb temperature, relative humidity, and having some control over the local physical environment. Greater effects were found with features of the psychosocial work environment including high job demands and low support. Only psychosocial work characteristics and control over the physical environment were independently associated with symptoms in the multivariate analysis. Conclusions: The physical environment of office buildings appears to be less important than features of the psychosocial work environment in explaining differences in the prevalence of symptoms

Supporting the emotional needs of young people in care: a qualitative study of foster carer perspectives

Young people who have been removed from their family home and placed in care have often experienced maltreatment and there is well-developed evidence of poor psychological outcomes. Once in care, foster carers often become the adult who provides day-to-day support, yet we know little about how they provide this support or the challenges to and facilitators of promoting better quality carer-child relationships. The aim of this study was to understand how carers support the emotional needs of the young people in their care and their views on barriers and opportunities for support. Participants were 21 UK foster carers, recruited from a local authority in England. They were predominantly female (86%), aged 42-65 years old and ranged from those who were relatively new to the profession (<12 months' experience) to those with over 30 years of experience as a carer. We ran three qualitative focus groups to gather in-depth information about their views on supporting their foster children's emotional well-being. Participants also completed short questionnaires about their training experiences and sense of competence. Only half of the sample strongly endorsed feeling competent in managing the emotional needs of their foster children. While all had completed extensive training, especially on attachment, diagnosis-specific training for mental health problems (eg, trauma-related distress, depression) was less common. Thematic analysis showed consistent themes around the significant barriers carers faced navigating social care and mental health systems, and mixed views around the best way to support young people, particularly those with complex mental health needs and in relation to reminders of their early experiences. Findings have important implications for practice and policy around carer training and support, as well as for how services support the mental health needs of young people in care

Polymorphisms in the circadian expressed genes PER3 and ARNTL2 are associated with diurnal preference and GNβ3 with sleep measures

Sleep and circadian rhythms are intrinsically linked, with several sleep traits, including sleep timing and duration, influenced by both sleep homeostasis and the circadian phase. Genetic variation in several circadian genes has been associated with diurnal preference (preference in timing of sleep), although there has been limited research on whether they are associated with other sleep measurements. We investigated whether these genetic variations were associated with diurnal preference (Morningness-Eveningness Questionnaire) and various sleep measures, including: the global Pittsburgh Sleep Quality index score; sleep duration; and sleep latency and sleep quality. We genotyped 10 polymorphisms in genes with circadian expression in participants from the G1219 sample (n = 966), a British longitudinal population sample of young adults. We conducted linear regressions using dominant, additive and recessive models of inheritance to test for associations between these polymorphisms and the sleep measures. We found a significant association between diurnal preference and a polymorphism in period homologue 3 (PER3) (P < 0.005, recessive model) and a novel nominally significant association between diurnal preference and a polymorphism in aryl hydrocarbon receptor nuclear translocator-like 2 (ARNTL2) (P < 0.05, additive model). We found that a polymorphism in guanine nucleotide binding protein beta 3 (GNβ3) was associated significantly with global sleep quality (P < 0.005, recessive model), and that a rare polymorphism in period homologue 2 (PER2) was associated significantly with both sleep duration and quality (P < 0.0005, recessive model). These findings suggest that genes with circadian expression may play a role in regulating both the circadian clock and sleep homeostasis, and highlight the importance of further studies aimed at dissecting the specific roles that circadian genes play in these two interrelated but unique behaviours

Increased vulnerability of rural children on antiretroviral therapy attending public health facilities in South Africa: a retrospective cohort study

BACKGROUND: A large proportion of the 340,000 HIV-positive children in South Africa live in rural areas, yet there is little sub-Saharan data comparing rural paediatric antiretroviral therapy (ART) programme outcomes with urban facilities. We compared clinical, immunological and virological outcomes between children at seven rural and 37 urban facilities across four provinces in South Africa. METHODS: We conducted a retrospective cohort study of routine data of children enrolled on ART between November 2003 and March 2008 in three settings, namely: urban residence and facility attendance (urban group); rural residence and facility attendance (rural group); and rural residents attending urban facilities (rural/urban group). Outcome measures were: death, loss to follow up (LTFU), virological suppression, and changes in CD4 percentage and weight-for-age-z (WAZ) scores. Kaplan-Meier estimates, logrank tests, multivariable Cox regression and generalized estimating equation models were used to compare outcomes between groups. RESULTS: In total, 2332 ART-naive children were included, (1727, 228 and 377 children in the urban, rural and rural/urban groups, respectively). At presentation, rural group children were older (6.7 vs. 5.6 and 5.8 years), had lower CD4 cell percentages (10.0% vs. 12.8% and 12.7%), lower WAZ scores (-2.06 vs. -1.46 and -1.41) and higher proportions with severe underweight (26% vs.15% and 15%) compared with the urban and rural/urban groups, respectively. Mortality was significantly higher in the rural group and LTFU significantly increased in the rural/urban group. After 24 months of ART, mortality probabilities were 3.4% (CI: 2.4-4.8%), 7.7% (CI: 4.5-13.0%) and 3.1% (CI: 1.7-5.6%) p = 0.0137; LTFU probabilities were 11.5% (CI: 9.3-14.0%), 8.8% (CI: 4.5-16.9%) and 16.6% (CI: 12.4-22.6%), p = 0.0028 in the urban, rural and rural/urban groups, respectively. The rural group had an increased adjusted mortality probability, adjusted hazards ratio 2.41 (CI: 1.25-4.67) and the rural/urban group had an increased adjusted LTFU probability, aHR 2.85 (CI: 1.41-5.79). The rural/urban group had a decreased adjusted probability of virological suppression compared with the urban group at any timepoint on treatment, adjusted odds ratio 0.67 (CI: 0.48-0.93). CONCLUSIONS: Rural HIV-positive children are a vulnerable group, exhibiting delayed access to ART and an increased risk of poor outcomes while on ART. Expansion of rural paediatric ART programmes, with future research exploring improvements to rural health system effectiveness, is required

Exploring the association between anxiety and conduct problems in a large sample of twins aged 2-4

Anxiety and conduct problems covary, yet studies have not explored the genetic and environmental origins of this association.We analyzed parent-reported anxiety and conduct problems in 6,783 pairs of twins at 2-, 3-, and 4-years of age. As anxiety and conduct problems were fairly stable across the three ages (average 1-year correlation was .53), ratings from all three were combined. The aggregate anxiety and conduct ratings correlated .33 for boys and .30 for girls. Bivariate genetic analyses indicated fairly low genetic correlations (.31 for boys, .16 for girls), and high shared environmental correlations (1.0 for boys and 0.99 for girls) between anxiety and conduct problems. Most of the phenotypic correlation was accounted for by shared environmental mediation (65% for boys and 94% for girls), indicating that many of the same family environmental factors are responsible for the development of both anxiety and conduct problems

It takes two to tango: improving patient referrals from the emergency department to inpatient clinicians

Background: The transfer of responsibility for patient care across clinical specialties is a complex process. Published and anecdotal data suggest that referrals often fail to meet the needs of one or both parties and that patient focus can be lost during the process. Little is known about the Australian situation. Methods: To obtain a more complete understanding of the referral process, including the nature of communication in an Australian context, we conducted semistructured interviews in a convenience sample of 25 volunteers. Two established strategies for analyzing qualitative data were used. Results: All respondents considered the following information essential components of a referral: an account of the patient’s current condition, a working diagnosis or problem statement and history of the presenting concern, key test results or tests awaiting results, a potential management plan, and any special characteristics of the patient. Respondents acknowledged implied, if not literal, power to accept or reject an emergency department (ED) referral and said the imbalance of power was reinforced when the ED physician was junior to the inpatient clinician. Respondents also noted that in addition to the predominant organizational culture, an independent culture is associated with specific shifts. Foremost among the nonclinical aspects of a referral considered to be important was the timeliness of the contact made to achieve the transition. Respondents also said the success of a referral depended on the speaking and listening abilities of all parties. The individual’s motivation to accept or reject a referral can also have an impact on communication. Conclusion: Respondents attributed the difficulty of negotiating the transfer of a patient’s care across the ED and inpatient interface to three distinct factors: variations in the clinical information required, the culture of the organization and of the clinical team in which the transaction takes place, and the characteristics of the individuals involved in the process. Improving communication skills has the potential to improve patient outcomes

Clinical communication skills learning outcomes among first year medical students are consistent irrespective of participation in an interview for admission to medical school

Background: Although contentious most medical schools interview potential students to assess personal abilities such as communication. Aims: To investigate any differences in clinical communication skills (CCS) between first year students admitted to UQ medical school with or without an admissions interview. Methods: A retrospective analysis of 1495 student assessment scores obtained after structured communication skills training (CCS) between 2007 and 2010. Results: The average assessment score was 3.76 ([95% CI, 3.73-3.78]) and adjusting for student characteristics, showed no main effect for interview (p=0.89). The strongest predictor of scores was gender with females achieving significantly higher scores (3.91 [95% CI, 3.54-4.28] vs. 3.76 [95% CI, 3.39-4.13]; p≤0.001). Conclusions: Data show no differences in post-training assessment measures between students who were interviewed during selection or not. Further research about the quality and retention of communications skills after training is warranted
