Exploring the perceptions of emotional distress among couples living with Type 2 diabetes and among diabetes healthcare providers, and consideration of support needs.

AIMS: To compare the emotional distress experienced by people with Type 2 diabetes with the perceptions of their partners, and to explore the perceptions of healthcare providers and how these differ from the perceptions and experiences of couples living with Type 2 diabetes regarding their support needs. METHODS: A purposive sample of people with Type 2 diabetes and their partners was recruited through Diabetes UK media outlets and support groups, while healthcare providers were recruited through hospital and diabetes education teams. Inductive thematic analysis was conducted. RESULTS: Seven people with Type 2 diabetes and six partners took part in separate semi-structured interviews and seven healthcare providers took part in focus groups. Themes emerged regarding unique psychological struggles for people with Type 2 diabetes: 'sense of restriction'; 'disempowerment'; and 'acceptance of diabetes'. For partners the themes of 'feeling responsible' and 'need for greater involvement' emerged. Common themes arising from people with Type 2 diabetes, partners and healthcare providers highlighted diabetes-related stresses: 'self-care struggles' and 'perceived need for appropriate psychological support'. A key theme drawn from healthcare providers was 'perceived professional barriers to psychological support', which captures concerns related to providing emotional support in clinical practice. CONCLUSIONS: People with Type 2 diabetes, partners, and healthcare providers share a common understanding of the emotional stresses of living with Type 2 diabetes, but also experience diabetes differently depending on their role and responsibilities. All face barriers that need to be considered to ensure that emotional support in diabetes is meaningful and feasible in routine practice.

Adult liver transplant for hepatocellular carcinoma at Wits Donald Gordon Medical Centre in Johannesburg, South Africa.

BACKGROUND: For those with unresectable hepatocellular carcinoma, liver transplantation is considered the treatment of choice. Since 2006, the transplant programme at Wits Donald Gordon Medical Centre (WDGMC) has offered liver transplantation for selected patients with hepatocellular carcinoma. While the number of patients transplanted was small, we are unaware of any published data from Southern Africa describing outcomes in this group of liver transplant recipients. The aim of this study was to describe our experience as a case series. METHODS: The records of all patients with HCC who underwent deceased donor liver transplantation between April 2006 and March 2018 were reviewed retrospectively. Data were extracted from transplant clinic patient files, histopathology and pathology laboratory reports and an existing database of all liver transplant recipients at WDGMC. Patient survival was calculated from the time of transplant and survival estimates were determined by the Kaplan-Meier method. RESULTS: Thirty-one liver transplants were reviewed. The most common causes of underlying liver disease were infectious, mostly hepatitis B virus, and diseases of lifestyle including alcoholic/non-alcoholic steatohepatitis. Median age at transplant, 57 years (IQR 44-65 years), was younger than observed internationally, but consistent with reports from Africa. Male recipients predominated, in keeping with published trends. Overall, outcomes were worse than expected but for recipients who were within the University of California at San Francisco (UCSF) criteria for transplantation; survival was comparable to previously published data. CONCLUSION: Despite limitations, this is the first documented series of patients undergoing liver transplantation for HCC in South Africa and demonstrates that good results can be achieved in appropriately selected patients.

The need for enhanced psychological support in esophageal cancer-an exploratory study of the perception of HCPs, patients, and carers.

Esophageal cancer patients and carers report significant levels of psychological distress. Despite this, only a small number of patients and carers engage with existing psychological services. This study aims to explore the perception of esophageal cancer patients, carers, and healthcare professionals (HCPs) of psychological distress and current provision of support, the need for and format of tailored support and barriers to patient/carer engagement. Semistructured interviews were undertaken with n = 14 esophageal cancer patients, carers, and HCPs. Directed content analysis was utilized to code the transcripts according to the preconceived categories as defined by study aim. Participants reported key periods for heightened distress around diagnosis and postsurgery on discharge from hospital. Provision of existing support was not felt to be adequate. A number of patient/carer barriers to engaging with support were identified in addition to HCP barriers. Participants perceived enhanced psychological support as a priority supportive care need with a number of recommendations for tailoring existing support services more adequately to the clinical population. With reports of heightened psychological morbidity yet with few esophageal cancer patients engaging with psychological services, there is an impetus to develop detailed care pathways to facilitate meeting this prioritized support need.

Peer advice giving from posttreatment to newly diagnosed esophageal cancer patients.

The benefits of peer support in cancer care include the sharing of information and experience, supporting adjustment by providing an illness trajectory which cancer patients can use to prepare for their own cancer journey. Information from peers is prioritized by esophageal cancer patients, yet the content of this experiential information is not well understood. The purpose of this study is to understand the content of peer advice giving from posttreatment to newly diagnosed esophageal cancer patients. Esophageal cancer survivors (n = 23) at median 67-months postdiagnosis completed a single open-ended survey item which asked for advice they would give to individuals newly diagnosed with esophageal cancer on how to cope emotionally with the cancer journey (including adjusting to life after treatment). Transcripts were assessed using qualitative content analysis, with five categories of advice identified: social support, psychological approach, realistic expectations, support from healthcare professionals and self-care. The categories of advice reported were distinct from information needs prioritized by clinicians. This study demonstrates that experiential information is accessible and has the potential to identify neglected information and supportive care needs, and may have a potential use in delivery of psychological support to newly diagnosed patients.

Patient anxiety and IV sedation in Northern Ireland.

BACKGROUND: In recent years there has been an increase in the provision of conscious sedation, which is said to be a safe and effective means of managing the anxious patient. However, there are no guidelines to aid the dental practitioner in assessing the patient's need for sedation based on their level of anxiety. AIMS AND METHODS: The present study investigated the importance of patient anxiety as an indicator for IV sedation, using focus groups to inform the development of narrative vignettes. Ninety-nine practitioners responded to a series of scenarios to determine whether the level of patient anxiety and the patient's demand for IV sedation influenced their decision making. RESULTS: Level of dental anxiety had a stronger influence on the clinician's decision making than patient demand, with increasing levels of dental anxiety being positively associated with the likelihood of clinicians indicating a need for IV patient sedation and also, the likelihood of clinicians providing IV sedation to these patients. Only 14% (n = 14) of respondents reported formally assessing dental anxiety. CONCLUSIONS: While dental anxiety is considered to be a key factor in determining the need for IV sedation, there is a lack of guidance regarding the assessment of anxiety among patients.

Psychological adjustment to Type 2 diabetes and relationship quality.

AIMS: To examine the associations between psychological adjustment to Type 2 diabetes and the reported quality and type of relationships with partners. METHODS: All participants (n=88) completed a number of questionnaires, including two measures of relationship quality: the Dyadic Adjustment Scale and the Personal Assessment of Intimacy in Relationships Scale, the Diabetes Quality of Life Scale and the ATT-19 (which assesses personal integration of diabetes). Additionally, HbA(1c) levels were obtained from medical notes. RESULTS: Measures of relationship quality significantly contributed to the explanation of two outcomes: personal integration of diabetes and satisfaction with the burden of self-management behaviours. More specifically, the findings demonstrate that a specific aspect of relationship quality--intimacy in recreational activities--is positively associated with the outcomes mentioned above. CONCLUSIONS: People with Type 2 diabetes who are not taking insulin, who share engagement in physical activities with their partner are more likely to be psychologically well-adjusted to their diagnosis of diabetes.

Self-perception in overweight and obese children: a cross-sectional study.

AIM: The aim of this study was to examine the relationship between obesity and self-esteem in children in relation to specific domains of their self-perception, and further to explore the extent to which this may vary by gender and economic circumstances. METHOD: A total of 211 children aged 8-9 years drawn from both advantaged and disadvantaged areas of Belfast completed the Harter Self-Perception Profile for Children and measures of body mass index were obtained. RESULTS: Overweight, impoverished children had significantly reduced social acceptance and physical competence scores. Boys had significantly lower scores than girls in the behavioural conduct domain. Girls had significantly lower scores than boys for the athletic competence. CONCLUSION: These results suggest that risk factors of increased weight and impoverished backgrounds have a combined negative effect, placing some children at increased risk of having lower self-perceptions in some, but not all domains. Health interventions for childhood obesity should consider the likelihood of specific relationships between physical and psychosocial factors.

Nonclinical aspects of biopharmaceutical development: discussion of case studies at a PhRMA-FDA workshop.

Robust assessments of the nonclinical safety profile of biopharmaceuticals are best developed on a scientifically justified, case-by-case basis, with consideration of the therapeutic molecule, molecular target, and differences/similarities between nonclinical species and humans (ICH S6). Significant experience has been gained in the 10 years ensuing since publication of the ICH S6 guidance. In a PhRMA-FDA-sponsored workshop, "Nonclinical Aspects of Biopharmaceutical Development," industry and US regulatory representatives engaged in exploration of current scientific and regulatory issues relating to the nonclinical development of biopharmaceuticals in order to share scientific learning and experience and to work towards establishing consistency in application of general principles and approaches. The proceedings and discussions of this workshop confirm general alignment of strategy and tactics in development of biopharmaceuticals with regard to such areas as species selection, selection of high doses in toxicology studies, selection of clinical doses, the conduct of developmental and reproductive toxicity (DART) studies, and assessment of carcinogenic potential. However, several important aspects, including, for example, appropriate use of homologues, nonhuman primates, and/or in vitro models in the assessment of risk for potential developmental and carcinogenic effects, were identified as requiring further scientific exploration and discussion.

The challenge of patients' unmet palliative care needs in the final stages of chronic illness.

BACKGROUND: There is consensus in the literature that the end of life care for patients with chronic illness is suboptimal, but research on the specific needs of this population is limited. AIM: This study aimed to use a mixed methodology and case study approach to explore the palliative care needs of patients with a non-cancer diagnosis from the perspectives of the patient, their significant other and the clinical team responsible for their care. Patients (n = 18) had a diagnosis of either end-stage heart failure, renal failure or respiratory disease. METHODS: The Short Form 36 and Hospital and Anxiety and Depression Questionnaire were completed by all patients. Unstructured interviews were (n = 35) were conducted separately with each patient and then their significant other. These were followed by a focus group discussion (n = 18) with the multiprofessional clinical team. Quantitative data were analysed using simple descriptive statistics and simple descriptive statistics. All qualitative data were taped, transcribed and analysed using Colaizzi's approach to qualitative analysis. FINDINGS: Deteriorating health status was the central theme derived from this analysis. It led to decreased independence, social isolation and family burden. These problems were mitigated by the limited resources at the individual's disposal and the availability of support from hospital and community services. Generally resources and support were perceived as lacking. All participants in this study expressed concerns regarding the patients' future and some patients described feelings of depression or acceptance of the inevitability of imminent death. CONCLUSION: Patients dying from chronic illness in this study had many concerns and unmet clinical needs. Care teams were frustrated by the lack of resources available to them and admitted they were ill-equipped to provide for the individual's holistic needs. Some clinicians described difficulty in talking openly with the patient and family regarding the palliative nature of their treatment. An earlier and more effective implementation of the palliative care approach is necessary if the needs of patients in the final stages of chronic illness are to be adequately addressed.

Facing up to binge drinking: reducing binge drinking in adolescent males.

OBJECTIVE: To evaluate the effectiveness of an orofacial trauma-based brief intervention, designed to raise adolescent males' awareness about the immediate dangers of binge drinking. DESIGN: Non-randomised controlled exploratory trial. SETTING: Secondary level schools. MATERIALS & METHODS: Pre, post and follow up validated questionnaires were used to assess a variety of descriptive data and changes in behaviour. Sixty Year 12 students were recruited in the pilot study and 182 in the definitive study. INTERVENTION: A brief visual presentation containing salient information and anonymised photographs relating to orofacial injuries. MAIN OUTCOME MEASURES: Intention to binge drink. RESULTS: The majority of participants obtained alcohol from off-licence or licenced premises. At the commencement of the study, 68% of the participants were regular drinkers. Whilst there was no change in drinking behaviour, the intervention group reported that it was significantly more likely (compared to the control group) that they would reduce their drinking to less than binge levels. CONCLUSION: The intervention resulted in participants reporting a more negative attitude towards binge drinking and increased their intention to disengage from binge drinking.

Do people with diabetes who need to talk want to talk?

AIM: Our objective was to determine whether people with diabetes who ask for psychological support are those who are experiencing clinically significant levels of psychological distress. METHOD: Three hundred people with diabetes were asked to complete psychometrically validated questionnaires that assessed subjective need and objective psychological distress. RESULTS: High levels of psychological distress were reported: 25% reported depressive symptomatology, 41% reported clinically significant levels of anxiety and 51% reported some binge eating behaviour. Participants also indicated a desire to talk to diabetes professionals about various problem areas in diabetes. Those reporting psychological distress, especially depression, were most likely to indicate a desire to talk to someone about living with diabetes. CONCLUSIONS: Those who want to talk are those who need to talk. Future service development issues should acknowledge the needs and expressed wishes of service users.

Rheumatologists' judgements about the efficacy of anti-TNF therapy in two neighbouring regions.

OBJECTIVES: The requirement in Northern Ireland to prescribe biological agents according to National Institute for Clinical Excellence/British Society for Rheumatology (NICE/BSR) guidelines and within a fixed budget has created a waiting list for treatment that has no parallel in the Republic of Ireland. The study investigated the bearing this situation may have had on consultants' judgements in the respective areas. METHODS: Seventy-eight case vignettes created from the data on real patients with RA treated with biologicals in the north and south of Ireland were appraised by nine southern and eight northern consultants, who judged the clinical benefit and significance of the patients' condition after a trial of therapy. Quantitative (clinical judgement analysis) and qualitative (focus groups) techniques were used. RESULTS: Northern consultants perceived a slightly greater degree of clinical benefit after a trial of therapy than southern consultants. Judgement models of northern and southern consultants were broadly comparable. The latter tended to be more uniform in their judgements than the southern group. Focus group discussions with consultants largely validated the findings of the quantitative analysis but revealed how clinical judgement analysis might be misled by gaming strategies. CONCLUSIONS: Despite the absence of overt rationing in the south of Ireland, as far as the judgement of therapeutic benefit from biologicals was concerned, the clinical judgement policies of practitioners were very similar to those in the north. The adoption of NICE/BSR guidelines in the north may have improved the uniformity of clinical practice in Northern Ireland.

A Comparative Analysis of the SF-12 and the SF-36 among Ischaemic Heart Disease Patients.

This paper investigated whether the SF-12 could replace the SF-36 in the measurement of health status among ischaemic heart disease patients. The SF-36 and SF-12 were administered to 105 cardiac patients. The SF-36 summary scores were strongly correlated and similar to the SF-12 summary scores. Also, the SF-12 scores were as powerful as the SF-36 summary scores in discriminating between subgroups of patients categorized according to their self-reported health status or angina classification. It is suggested that when there is a need to collect routine information about cardiac patients' general physical and mental health, the SF-12 is preferable to the SF-36 because of its brevity and acceptability to patients.

Computational learning techniques for intraday FX trading using popular technical indicators.

We consider strategies which use a collection of popular technical indicators as input and seek a profitable trading rule defined in terms of them. We consider two popular computational learning approaches, reinforcement learning and genetic programming, and compare them to a pair of simpler methods: the exact solution of an appropriate Markov decision problem, and a simple heuristic. We find that although all methods are able to generate significant in-sample and out-of-sample profits when transaction costs are zero, the genetic algorithm approach is superior for non-zero transaction costs, although none of the methods produce significant profits at realistic transaction costs. We also find that there is a substantial danger of overfitting if in-sample learning is not constrained.

How well do elderly people complete individualised quality of life measures: an exploratory study.

This research note describes and discusses a study which investigated the feasibility of using an individualised approach to measure the quality of life (QoL) of a sample of older people who were in receipt of an early hospital discharge service. Most participants (86%) were able to identify areas of their lives which were important to them, rate their level of functioning on each of these areas and rank their life areas in order of importance. However, 39% were unable to quantify the relative importance of each area of life. Indeed, the majority (57%) of participants who were over 75 years old could not complete this 'weighting' or evaluative stage. The results suggest that the phenomenological approach to measuring QoL may be employed successfully with older people but that the 'weighting' system used by existing individualised QoL measures needs to be refined, especially when assessing people over 75.

Measuring the health related quality of life of people with ischaemic heart disease.

OBJECTIVES: To inform researchers and clinicians about the most appropriate generic and disease specific measures of health related quality of life for use among people with ischaemic heart disease. METHODS: MEDLINE and BIDS were searched for research papers which contained a report of at least one of the three most common generic instruments or at least one of the five disease specific instruments used with ischaemic heart disease patients. Evidence for the validity, reliability, and sensitivity of these instruments was critically appraised. RESULTS: Of the three generic measures-the Nottingham health profile, sickness impact profile, and short form 36 (SF-36)-the SF-36 appears to offer the most reliable, valid, and sensitive assessment of quality of life. However, a few of the SF-36 subscales lack a sufficient degree of sensitivity to detect change in a patient's clinical condition. According to the best available evidence, the quality of life after myocardial infarction questionnaire should be preferred to the Seattle angina questionnaire, the quality of life index cardiac version, the angina pectoris quality of life questionnaire, and the summary index. Overall, research on disease specific measures is sparse compared to the number of studies which have investigated generic measures. CONCLUSIONS: An assessment of the quality of life of people with ischaemic heart disease should comprise a disease specific measure in addition to a generic measure. The SF-36 and the quality of life after myocardial infarction questionnaire (version 2) are the most appropriate currently available generic and disease specific measures of health related quality of life, respectively. Further research into the measurement of health related quality of life of people with ischaemic heart disease is required in order to address the problems (such as lack of sensitivity to detect change) identified by the review.

Selecting a measure of health related quality of life.

Quality of life is becoming recognized increasingly as an important outcome measure which needs to be considered by social workers. However, there does not appear to be a clear consensus about the definition of quality of life. In addition, social workers are likely to experience difficulties choosing and applying an appropriate instrument with which to measure quality of life because of the many available instruments purporting to assess quality of life. This paper discusses the definition of health-related quality of life and explains the main measurement properties of an instrument that must be appraised when considering whether or not an instrument is appropriate. The paper will assist social workers to make an informed choice about measures of health-related quality of life.

The adaptations of a quality of life questionnaire for routine use in clinical practice: the Chronic Respiratory Disease Questionnaire in cystic fibrosis.

The assessment of quality of life (QoL) is necessary to monitor the course of disease and to assess the effect of new and existing interventions in clinical practice. This will only be achieved if QoL can be measured accurately and routinely. The aim of this study was to demonstrate the methodology involved in the adaptation and shortening of the Chronic Respiratory Disease Questionnaire (CRDQ) in a population of adults with cystic fibrosis (CF). A single interviewer administered the CRDQ to a sample of 45 adult patients (32 males) with CF prior to assessment of spirometric measures of lung function. Those patients whose lung function was stable at the time of study and who could attend for a retest within 14 days were asked to complete the questionnaire at a subsequent visit (n = 10). The mean interval between visits was 7 days (range 5-14 days). Correlations between spirometry and CRDQ dimensions ranged from -0.003 to 0.426. The fatigue, emotion and mastery dimensions showed high internal consistency and adequate construct validity. In the small number of patients suitable for retest, the results indicated that the dimensions exhibited adequate test-retest reliability. In contrast, low internal consistency was demonstrated for the dyspnoea dimension. The fatigue, emotion and mastery dimensions could be reduced, in terms of their number of items, without a substantial loss in explanatory power. This study suggests that QoL measurement can be made convenient and, thus, more easily accessible for routine clinical assessment.

A home from hospital service for older people.

Current policy and practice emphasises much more than ever before a need for purchasers and providers to reduce appropriately the length of hospital stay. Consequently, a number of early discharge "schemes" have been developed. This paper presents the findings from an evaluation of a "home from hospital" (HFH) scheme. The HFH service provides a maximum of six weeks' intensive domiciliary care for older people on their discharge from hospital. The aim of the service is to facilitate early discharge from hospital and to assist patients to regain independence. The study reported here elicited the views and perceptions of clients and professionals involved in the HFH scheme about the quality, efficiency and effectiveness of the service. Seventy-five patients were discharged from hospital to the HFH scheme during a two month period and those who consented to participate in the study were interviewed after discharge from the HFH service (n = 40). Participants had attended hospital for various conditions but the largest group were fracture patients. Hospital staff and community based professionals completed a questionnaire about the service. Overall, patients and professionals perceived the HFH scheme as a beneficial service, though some minor problems existed at an individual level. Clients' dependency levels generally decreased during their time on the scheme. Research using a controlled design is necessary in order to draw firm conclusions about the cost-effectiveness of a HFH service. Overall, home-from-hospital appears to be an effective model of an early discharge scheme worthy of further attention.
