Health concerns of cancer survivors after primary anti-cancer treatment

PURPOSE

Cancer survivors experience significant health concerns compared to the general population. Sydney Survivorship Clinic (SSC) is a multi-disciplinary clinic aiming to help survivors treated with curative intent manage side effects, and establish a healthy lifestyle. Here, we determine the health concerns of survivors post-primary treatment.

METHODS

Survivors completed questionnaires assessing symptoms, quality of life (QOL), distress, diet, and exercise before attending SSC, and a satisfaction survey after. Body mass index (BMI), clinical findings and recommendations were reviewed. Descriptive statistical methods were used.

RESULTS

Overall, 410 new patients attended SSC between September 2013 and April 2018, with 385 survivors included in analysis: median age 57 years (range 18-86); 69% female; 43% breast, 31% colorectal and 19% haematological cancers. Median time from diagnosis, 12 months. Common symptoms of at least moderate severity: fatigue (45%), insomnia (37%), pain (34%), anxiety (31%) and with 56% having > 5 moderate-severe symptoms. Overall, 45% scored distress ≥ 4/10 and 62% were rated by clinical psychologist as having 'fear of cancer recurrence'. Compared to population mean of 50, mean global QOL T-score was 47.2, with physical and emotional well-being domains most affected. Average BMI was 28.2 kg/m² (range 17.0-59.1); 61% overweight/obese. Only 31% met aerobic exercise guidelines. Overall, 98% 'agreed'/'completely agreed' attending the SSC was worthwhile, and 99% would recommend it to others.

CONCLUSION

Distress, fear of cancer recurrence, fatigue, obesity and sedentary lifestyle are common in cancer survivors attending SSC and may best be addressed in a multi-disciplinary Survivorship Clinic to minimise longer-term effects. This model is well-rated by survivors.

The effect of temperature, farm density and foot-and-mouth disease restrictions on the 2007 UK bluetongue outbreak

In 2006, bluetongue (BT), a disease of ruminants, was introduced into northern Europe for the first time and more than two thousand farms across five countries were affected. In 2007, BT affected more than 35,000 farms in France and Germany alone. By contrast, the UK outbreak beginning in 2007 was relatively small, with only 135 farms in southeast England affected. We use a model to investigate the effects of three factors on the scale of BT outbreaks in the UK: (1) place of introduction; (2) temperature; and (3) animal movement restrictions. Our results suggest that the UK outbreak could have been much larger had the infection been introduced into the west of England either directly or as a result of the movement of infected animals from southeast England before the first case was detected. The fact that air temperatures in the UK in 2007 were marginally lower than average probably contributed to the UK outbreak being relatively small. Finally, our results indicate that BT movement restrictions are effective at controlling the spread of infection. However, foot-and-mouth disease restrictions in place before the detection and control of BT in 2007 almost certainly helped to limit BT spread prior to its detection.

Critical care usage after major gastrointestinal and liver surgery: a prospective, multicentre observational study

BACKGROUND

Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery.

METHODS

This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy.

RESULTS

Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI.

CONCLUSIONS

After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

The role of climate change in a developing threat: the case of bluetongue in Europe

There is a solid theoretical basis for expecting climate change to have a considerable effect on the infectious diseases of humans, animals and plants. Vector-borne diseases are the most likely to be affected. It is, however, rare to observe such impacts, as diseases are also influenced by many other drivers, some of which may have stronger effects over shorter time scales than climate change. Nevertheless, there is evidence that our warming climate has already influenced some animal diseases, of which bluetongue is considered a prime example. Bluetongue emerged dramatically in southern Europe after 1998 and in northern Europe from 2006. While the speed and scale of this emergence is a challenge to explain, there is evidence, principally from the development of climate-driven models, that recent climate change has played a significant role. Climate-driven models point to an increase in the risk of bluetongue transmission in Europe in recent decades, caused by an increased suitability of parts of southern Europe for the Afro-tropical biting midge, Culicoides imicola, as well as an increase in the vectorial capacity of indigenous Culicoides vectors in northern Europe. Farm-to-farm transmission models of bluetongue in England and Wales under predicted climatic conditions further suggest that, under high-emission scenarios, the scale of future outbreaks could far exceed those experienced to date. The role of climate change in the developing threat of animal disease is, therefore, likely to be economically and socially costly, unless lower emission targets can be set and followed.

Telephone-based CBT and the therapeutic relationship: The views and experiences of IAPT practitioners in a low-intensity service

WHAT IS KNOWN ON THE SUBJECT

There is a move towards the use of new ways of delivering mental health care, particularly via an increased use of telephone therapies. Although some studies have noted the advantages of telephone-delivered therapies (e.g., removing access barriers) and reported on equivalent therapeutic effects when compared to face-to-face, there are concerns about how telephone-based therapy adversely affects the therapeutic relationship.

WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE

It contributes new knowledge regarding psychological practitioners' experience and views about using telephone-based therapies and how this affects the therapeutic relationship.

WHAT ARE THE IMPLICATIONS FOR PRACTICE

This paper provides data about the new practitioner workforce (IAPT Psychological Wellbeing Practitioners) and adds to a growing area of research regarding their clinical role. It has relevance for mental health nursing, because health services internationally and across the professions are exploring how telehealth can improve health care. This paper suggests that mental health services need to focus on what type of therapeutic relationship their practice facilitates and on offering transparency to service users. It concludes that telephone work in IAPT can accommodate a working alliance, but not other types of therapeutic relationship, which practitioners and service users hoped for. Services need to focus on what facilitates and inhibits deeper therapeutic closeness and connection.

ABSTRACT

Introduction Over-the-telephone (OTT)-delivered psychological therapies as an alternative method to face-to-face (F2F) are becoming more prevalent in mental health care. Research suggests a range of benefits of OTT use in therapy, but there are growing concerns about its consequences for the therapeutic relationship. This paper presents new knowledge regarding psychological practitioners' experience and views of OTT work and its potential effects on the therapeutic relationship in the context of the UK's Increasing Access to Psychological Therapy (IAPT) programme. Aim This paper presents IAPT practitioners' experiences and views of OTT work and its potential effects on the therapeutic relationship. Methods Completed questionnaires (exploring OTT versus F2F work) which were distributed to IAPT practitioners revealed a concern about the therapeutic relationship in OTT. To explore this further, nine in-depth semi-structured interviews with PWPs were conducted and the findings from this qualitative study are reported here. Results Practitioners noted OTT use facilitated access and flexibility for service users; however, they expressed some concern over the adverse effect of OTT on the therapeutic relationship. Discussion Although a working alliance was possible OTT, this research suggests the type of therapeutic relationship formed OTT in a "low contact-high volume" service such as IAPT needs to be better defined. By addressing this, dissonance which might arise between practitioner aims and the aims of IAPT can be reduced. This research also contributes to wider debates regarding mental health care and its provision in the UK. Implications for practice This paper concludes that mental health services need to focus on what type of therapeutic relationship their practice facilitates and to offer transparency to service users. The findings suggest that telephone work in IAPT can accommodate a working alliance, but not other types of therapeutic relationship, which practitioners and service users hoped for. Services need to offer a more nuanced understanding of the concept of a therapeutic relationship and focus on what facilitates and inhibits deeper therapeutic closeness and connection.

Widespread white matter microstructural differences in schizophrenia across 4322 individuals: results from the ENIGMA Schizophrenia DTI Working Group

The regional distribution of white matter (WM) abnormalities in schizophrenia remains poorly understood, and reported disease effects on the brain vary widely between studies. In an effort to identify commonalities across studies, we perform what we believe is the first ever large-scale coordinated study of WM microstructural differences in schizophrenia. Our analysis consisted of 2359 healthy controls and 1963 schizophrenia patients from 29 independent international studies; we harmonized the processing and statistical analyses of diffusion tensor imaging (DTI) data across sites and meta-analyzed effects across studies. Significant reductions in fractional anisotropy (FA) in schizophrenia patients were widespread, and detected in 20 of 25 regions of interest within a WM skeleton representing all major WM fasciculi. Effect sizes varied by region, peaking at (d=0.42) for the entire WM skeleton, driven more by peripheral areas as opposed to the core WM where regions of interest were defined. The anterior corona radiata (d=0.40) and corpus callosum (d=0.39), specifically its body (d=0.39) and genu (d=0.37), showed greatest effects. Significant decreases, to lesser degrees, were observed in almost all regions analyzed. Larger effect sizes were observed for FA than diffusivity measures; significantly higher mean and radial diffusivity was observed for schizophrenia patients compared with controls. No significant effects of age at onset of schizophrenia or medication dosage were detected. As the largest coordinated analysis of WM differences in a psychiatric disorder to date, the present study provides a robust profile of widespread WM abnormalities in schizophrenia patients worldwide.

Abstract P3-05-01: Immune and transcriptional signatures of dendritic dell (DC) vaccination combined with chemotherapy in locally advanced, triple-negative breast cancer (TNBC) patients

BACKGROUND: Women with TNBC who do not achieve a pathologic complete response (pCR) with preoperative (preop) chemotherapy have a high risk of recurrence and death from BC. Immunotherapy is an attractive strategy as human BCs can be immunogenic, and enhancing the immune effector function may augment the cytotoxic effects of standard therapies.

CLINICAL TRIAL: Following IRB-approved informed consent, 10 pts with locally advanced TNBC received preop dose-dense doxorubicin/cyclophosphamide (AC) followed by paclitaxel and carboplatin (TCb) chemotherapy, combined with antigen-loaded (TNBC antigens: Cyclin B1, WT1, and control viral antigens: CEF) autologous monocyte-derived DC vaccinations administered intratumorally and subcutaneously. DCs were generated with GM-CSF and type I interferon, loaded with antigen in the form of long peptides and activated with innate ligands (LPS and Clo75) and CD40 ligand. Vaccines were given at 4 time points prior to definitive surgery, and 3 times post-surgery, pre- and post-radiation therapy (RT). Safety was the primary study endpoint, and pCR rate in breast and axilla was a secondary endpoint. Correlative studies included assessment of immune response via ELISpot and transcriptional profiling of blood samples collected over time.

RESULTS: All pts received the 4 vaccines during preop chemotherapy, and 7/10 received all 7 vaccines. At the time of definitive surgery, 4 pts achieved a pCR, 3 pts had macroscopic residual disease in the breast and axillary lymph nodes, and 3 pts had residual cancer burden scores of 1. As of June 1, 2017, all pts have been in follow-up for at least 1 year s/p completion of all vaccines, and 7/10 patients have no evidence of disease.

To assess immune signatures with IFN-γ-ELISpot, PBMCs from baseline (BL) and several time points during vaccine treatment were cultured with control peptides or with peptide libraries covering vaccine antigens. Using a linear mixed model to account for repeated and missing observations we found statistically significant (α = 0.05) increases in Cyclin B1, WT1, and CEF ELISpots in at least 1 time point post-DC vaccination and in follow-up. Compared to BL, Cyclin B1 and WT1 increased at 3 day pre-RT in 8/10 and 7/10 pts, respectively. To assess transcriptional signatures, a linear mixed model was utilized to determine statistically significant differences in fold-change over time compared to the BL and healthy controls. Modular analysis of differentially expressed transcripts at BL revealed downregulation of transcripts related to the monocyte lineage in 7/10 pts. Longitudinal analysis revealed profound transcriptional changes during AC with downregulation of lymphocyte modules and upregulation of innate and inflammation modules. While the latter ones have normalized during TCb and follow-up, T cell module remained substantially downregulated throughout treatment and follow-up.

CONCLUSIONS: Combination of preop chemotherapy and intratumoral and subcutaneous autologous DC vaccination is safe in locally advanced TNBC pts and is linked with profound changes in immune transcription signatures and with expansion of antigen-specific immune responses that can be detected in IFN-γ ELISpot.

Hydroacoustics as a tool to examine the effects of Marine Protected Areas and habitat type on marine fish communities

Hydroacoustic technologies are widely used in fisheries research but few studies have used them to examine the effects of Marine Protected Areas (MPAs). We evaluate the efficacy of hydroacoustics to examine the effects of closure to fishing and habitat type on fish populations in the Cabo Pulmo National Park (CPNP), Mexico, and compare these methods to Underwater Visual Censuses (UVC). Fish density, biomass and size were all significantly higher inside the CPNP (299%, 144% and 52% respectively) than outside in non-MPA control areas. These values were much higher when only accounting for the reefs within the CPNP (4715%, 6970% and 97% respectively) highlighting the importance of both habitat complexity and protection from fishing for fish populations. Acoustic estimates of fish biomass over reef-specific sites did not differ significantly from those estimated using UVC data, although acoustic densities were less due to higher numbers of small fish recorded by UVC. There is thus considerable merit in nesting UVC surveys, also providing species information, within hydroacoustic surveys. This study is a valuable starting point in demonstrating the utility of hydroacoustics to assess the effects of coastal MPAs on fish populations, something that has been underutilised in MPA design, formation and management.
