RESUMO

BACKGROUND: Personality has been implicated in stroke death. However, the role of personality in stroke incidence is unclear. PURPOSE: Our primary aim was to investigate associations between optimism, determination, control, and the "Big Five" personality traits on incident stroke. A secondary aim was to assess the potential mediating role of health behaviors in the personality-stroke relationship. METHODS: A total of 3,703 stroke-free participants from the English Longitudinal Study of Ageing provided data on personality using the Midlife Development Inventory at Wave 5 (2010/11). Self-reported incident stroke was assessed from Waves 6 to 8 (2012-2017). Associations were modeled using discrete-time survival proportional odds logistic models. Analyses were adjusted for sociodemographic factors, history of other cardiometabolic diseases, and health behaviors. RESULTS: Over 6 years follow-up there were 125 incident strokes. Higher optimism (hazard ratio [HR] = 0.66; 95% confidence interval [CI] 0.53, 0.82), openness (HR = 0.72; 95% CI 0.53, 0.98), and conscientiousness (HR = 0.59; 95% CI 0.42, 0.84) were associated with reduced incident stroke risk in unadjusted models. After adjustment for sociodemographic factors and history of cardiometabolic disease, only the association between optimism and incident stroke remained significant (HR = 0.72; 95% CI 0.57, 0.92). The effect of optimism remained significant in a final model adjusting for health behaviors (HR = 0.75; 95% CI 0.60, 0.96). There was evidence of a small but significant mediating effect of physical activity. CONCLUSIONS: Higher trait optimism was associated with reduced stroke risk. This association was partially mediated by physical activity albeit the effect was small, and caution warranted inferring causality. The interplay of personality, behavior, and clinical risk factors in stroke incidence and survivorship needs further investigation.


Personality can influence health. Research has linked traits such as optimism with reduced risk of heart attack. This study set out to investigate whether optimism and other personality traits could also influence the risk of stroke. A total of 3,703 people aged 50 and over living in England filled in questionnaires on personality. They were then followed for 6 years to see who developed stroke. The study found that more optimistic people had a reduced risk of stroke. People who had more conscientious and more open personality types also had a lower risk of stroke. However, the strongest effects were found for optimism, where optimistic people had a lower stroke risk regardless of their clinical risk or health behaviors. It is unknown why optimism may help reduce stroke risk. One possibility coming from the study data suggests that optimistic people are more likely to be physically active which then helps reduce stroke risk. More research is needed to understand how personality might influence health behaviors to reduce the risk of people having a stroke.

RESUMO

Debilitating fatigue is common in people living with kidney disease and often persists after a kidney transplant. Current understanding of fatigue is centered around pathophysiological processes. Little is known about the role of cognitive and behavioral factors. The aim of this study was to evaluate the contribution of these factors to fatigue among kidney transplant recipients (KTRs). A cross-sectional study of 174 adult KTRs who completed online measures of fatigue, distress, illness perceptions, and cognitive and behavioral responses to fatigue. Sociodemographic and illness-related information was also collected. 63.2% of KTRs experienced clinically significant fatigue. Sociodemographic and clinical factors explained 16.1% and 31.2% of the variance in the fatigue severity and fatigue impairment, respectively, increasing by 28% and 26.8% after adding distress. In adjusted models, all the cognitive and behavioral factors except for illness perceptions were positively associated with increased fatigue-related impairment, but not severity. Embarrassment avoidance emerged as a key cognition. In conclusion, fatigue is common following kidney transplantation and associated with distress and cognitive and behavioral responses to symptoms, particularly embarrassment avoidance. Given the commonality and impact of fatigue in KTRs, treatment is a clinical need. Psychological interventions targeting distress and specific beliefs and behaviors related to fatigue may be beneficial.

RESUMO

Unspecified kidney donors (UKDs) are approached cautiously by some transplant professionals. The aim of this study was to interrogate the views of UK transplant professionals towards UKDs and identify potential barriers. A purposely designed questionnaire was validated, piloted and distributed amongst transplant professionals at each of the 23 UK transplant centres. Data captured included personal experiences, attitudes towards organ donation, and specific concerns about UKD. 153 responses were obtained, with representation from all UK centres and professional groups. The majority reported a positive experience with UKDs (81.7%; p < 0.001) and were comfortable with UKDs undergoing major surgery (85.7%; p < 0.001). 43.8% reported UKDs to be more time consuming and 52% felt that a mental health assessment should take place before any medical tests. 77% indicated the need for a lower age limit. The suggested age range was broad (16-50 years). Adjusted mean acceptance scores did not differ by profession (p = 0.68) but higher volume centres were more accepting (46.2 vs. 52.9; p < 0.001). This is the first quantitative study of acceptance by transplant professionals to a large national UKD programme. Support is broad, however potential barriers to donation have been identified, including lack of training. Unified national guidance is needed to address these.

RESUMO

Unspecified kidney donation (UKD) has made substantial contributions to the UK living donor programme. Nevertheless, some transplant professionals are uncomfortable with these individuals undergoing surgery. This study aimed to qualitatively explore the attitudes of UK healthcare professionals towards UKD. An opportunistic sample was recruited through the Barriers and Outcomes in Unspecified Donation (BOUnD) study covering six UK transplant centres: three high volume and three low volume centres. Interview transcripts were analysed using inductive thematic analysis. The study provided comprehensive coverage of the UK transplant community, involving 59 transplant professionals. We identified five themes: staff's conception of the ethics of UKD; presence of the known recipient in the donor-recipient dyad; need for better management of patient expectations; managing visceral reactions about the "typical" unspecified kidney donor; complex attitudes toward a promising new practice. This is the first in-depth qualitative study of attitudes of transplant professionals towards UKD. The data uncovered findings with strong clinical implications for the UKD programme, including the need for a uniform approach towards younger candidates that is adhered to by all transplant centres, the need to equally extend the rigorous assessment to both specified and unspecified donors, and a new approach to managing donor expectations.

RESUMO

BACKGROUND: Services for patients with kidney disease underwent radical adaptations in response to the COVID-19 pandemic. We undertook an online national survey of UK kidney centres to understand the nature, range, and degree of variation in these changes and to explore factors contributing to differing practice. METHODS: The survey was designed by a multidisciplinary team of kidney professionals, service users and researchers. It enquired about centre services and staffing, including psychosocial provision, and changes to these in response to the COVID-19 pandemic. Links to the survey were sent to all 68 UK kidney centres and remained active from December 2021 to April 2022, and a revised version to nurses in late 2022 for additional data. Quantitative data were analysed descriptively. Content analysis on free-text responses identified common themes. RESULTS: Analysable responses were received from 41 out of the 68 UK centres (60%), with partial data from an additional 7 (11%). Adaptations were system-wide and affected all aspects of service provision. Some changes were almost universal such as virtual consultations for outpatient appointments, with significant variation in others. Outpatient activity varied from fully maintained to suspended. Many centres reduced peritoneal dialysis access provision but in some this was increased. Centres considered that changes to transplant surgical services and for patients with advanced CKD approaching end-stage kidney disease had the greatest impact on patients. Few centres implemented adjustments aimed at vulnerable and underrepresented groups, including the frail elderly, people with language and communication needs, and those with mental health needs. Communication issues were attributed to rapid evolution of the pandemic, changing planning guidance and lack of resources. Staffing shortages, involving all staff groups particularly nurses, mainly due to COVID-19 infection and redeployment, were compounded by deficiencies in staffing establishments and high vacancy levels. Centres cited three main lessons influencing future service delivery, the need for service redesign, improvements in communication, and better support for staff. CONCLUSION: Kidney centre responses to the pandemic involved adaptations across the whole service. Though some changes were almost universal, there was wide variation in other areas. Exploring the role of centre characteristics may help planning for potential future severe service disruptions.

RESUMO

BACKGROUND: Testing positive for human papillomavirus (HPV) at cervical cancer screening has been associated with heightened anxiety. To date, the cognitive determinants of heightened anxiety remain unclear, making it difficult to design effective interventions. PURPOSE: This study investigated latent illness representation profiles in women testing positive for HPV with no abnormal cells (normal cytology) and explored associations between these profiles and anxiety. METHODS: Women aged 24-66 (n = 646) who had tested HPV-positive with normal cytology at routine HPV primary screening in England completed a cross-sectional survey shortly after receiving their result. RESULTS: Latent profile analysis identified three distinct profiles of illness representations (termed "adaptive," "negative," and "negative somatic"), which differed significantly in their patterns of illness perceptions. Hierarchal linear regression revealed that these latent illness representation profiles accounted for 21.8% of the variance in anxiety, after adjusting for demographic and clinical characteristics. When compared with adaptive representations (Profile 1), women with negative representations (Profile 2) and negative somatic representations (Profile 3) had significantly higher anxiety, with clinically meaningful between-group differences (mean difference [MD] = 17.26, confidence interval [CI]: 14.29-20.22 and MD = 13.20, CI: 9.45-16.96 on the S-STAI-6, respectively). CONCLUSION: The latent illness representation profiles identified in this study provide support for the role of negative beliefs contributing to anxiety in women testing HPV-positive with normal cytology. Characteristics specific to subgroups of highly anxious women (Profiles 2 and 3) could be used by policymakers to target information in routine patient communications (e.g., test result letters) to reduce unnecessary burden. Future research should adopt longitudinal designs to understand the trajectory of illness representations from HPV diagnosis through to clearance versus persistence.

RESUMO

BACKGROUND: Many people living with chronic kidney disease (CKD) are iron deficient, even though they may not be anaemic. The Iron and Muscle study aims to evaluate whether iron supplementation reduces symptoms of fatigue, improves muscle metabolism, and leads to enhanced exercise capacity and physical function. We report here the trial design and baseline characteristics. METHODS: This is a prospective, double-blind multicentre randomised controlled trial (RCT) including 75 non-dialysis stage 3-4 CKD patients with iron deficiency but without anaemia. Patients were randomly (1:1) assigned to either: i) intravenous iron therapy, or ii) placebo, with concurrent recruitment of eight CKD non-iron deficient participants and six healthy volunteers. The primary outcome of the study is the six-minute walk test (6MWT) distance between baseline and four-weeks. An additional exercise training programme for patients in both groups was initiated and completed between 4 and 12 weeks, to determine the effect of iron repletion compared to placebo treatment in the context of patients undertaking an exercise programme. Additional secondary outcomes include fatigue, physical function, muscle strength, muscle metabolism, quality of life, resting blood pressure, clinical chemistry, safety and harms associated with the iron therapy intervention and the exercise training intervention, and hospitalisations. All outcomes were conducted at baseline, 4, and 12 weeks, with a nested qualitative study, to investigate the experience of living with iron deficiency and intervention acceptability. The cohort have been recruited and baseline assessments undertaken. RESULTS: Seventy-five individuals were recruited. 44% of the randomised cohort were male, the mean (SD) age was 58 (14) years, and 56% were White. Body mass index was 31 (7) kg/m2; serum ferritin was 59 (45) µg/L, transferrin saturation was 22 (10) %, and haemoglobin was 125 (12) g/L at randomisation for the whole group. Estimated glomerular filtration rate was 35 (12) mL/min/1.73 m2 and the baseline 6MWT distance was 429 (174) m. CONCLUSION: The results from this study will address a substantial knowledge gap in the effects of intravenous iron therapy, and offer potential clinical treatment options, to improve exercise capacity, physical function, fatigue, and muscle metabolism, for non-dialysis patients with CKD who are iron-deficient but not anaemic. It will also offer insight into the potential novel effects of an 8-week exercise training programme. TRIAL REGISTRATION: EudraCT: 2018-000,144-25 Registered 28/01/2019.

RESUMO

BACKGROUND: To our knowledge this was the first study aimed at examining the associations between illness perceptions and heart-focussed anxiety amongst individuals with hypertrophic cardiomyopathy. The secondary aim of this study was to examine the contribution of demographic, clinical and lifestyle factors to heart-focussed anxiety in this patient group. METHODS: This cross-sectional sample of 153 patients, recruited through social media platforms, completed the Revised Illness Perception Questionnaire (IPQ-R), Cardiac-Focussed Anxiety Questionnaire (CAQ) as well as questionnaires covering demographic, lifestyle and clinical factors. RESULTS: Hierarchical regression analyses found that illness perceptions significantly accounted for variability in heart-focussed anxiety beyond the effects of clinical, demographic and lifestyle factors. Illness perceptions accounted for 22% of the variability in heart-focussed anxiety, while demographic factors accounted for 12%, and lifestyle and clinical parameters accounted for 17%. CONCLUSIONS: Whilst longitudinal studies are warranted to confirm these findings, psychological interventions grounded in the Common-Sense Model may have the potential to better support patients coping with hypertrophic cardiomyopathy related anxiety.

RESUMO

The health benefits of breastfeeding are well recognised, but breastfeeding rates worldwide remain suboptimal. Breastfeeding outcomes have yet to be explored among women who give birth to macrosomic (birthweight ≥4000 g) infants, a cohort for whom the benefits of breastfeeding may be particularly valuable, offering protection against later-life morbidity associated with macrosomia. This longitudinal prospective cohort study aimed to identify whether women who give birth to macrosomic infants are at greater risk of breastfeeding non-initiation or exclusive breastfeeding (EBF) cessation. A total of 328 women in their third trimester were recruited from hospital and community settings and followed to 4 months post-partum. Women gave birth to 104 macrosomic and 224 non-macrosomic (<4000 g) infants between 2018 and 2020. Longitudinal logistic regression models calculated odds ratios (ORs) and 95% confidence intervals (CIs) to assess likelihood of EBF at four timepoints post-partum (birth, 2 weeks, 8 weeks, and 4 months) between women who gave birth to macrosomic and non-macrosomic infants, adjusted for maternal risk (obesity and/or diabetes), ethnicity and mode of birth. Macrosomic infants were more likely to be exclusively breastfed at birth and 2 weeks post-partum than non-macrosomic infants with adjusted OR = 1.94 (95% CI: 0.90, 4.18; p = 0.089) and 2.13 (95% CI: 1.11, 4.06; p = 0.022), respectively. There were no statistically significant associations between macrosomia and EBF at 8 weeks or 4 months post-partum. Macrosomia may act as a protective factor against early formula-milk supplementation, increasing the likelihood of EBF in the early post-partum period, but rates of exclusive breastfeeding continued to decline over the first 4 months post-partum.

RESUMO

AIMS/HYPOTHESIS: Loneliness is associated with all-cause mortality and coronary heart disease. However, the prospective relationship between loneliness and type 2 diabetes onset is unclear. METHODS: We conducted a longitudinal observational population study with data on 4112 diabetes-free participants (mean age 65.02 ± 9.05) from the English Longitudinal Study of Ageing. Loneliness was assessed in 2004-2005 using the revised University of California, Los Angeles (UCLA) Loneliness Scale. Incident type 2 diabetes cases were assessed from 2006 to 2017. Associations were modelled using Cox proportional hazards regression, adjusting for potential confounders, which included cardiometabolic comorbidities. RESULTS: A total of 264 (6.42%) participants developed type 2 diabetes over the follow-up period. Loneliness was a significant predictor of incident type 2 diabetes (HR 1.46; 95% CI 1.15, 1.84; p = 0.002) independent of age, sex, ethnicity, wealth, smoking status, physical activity, alcohol consumption, BMI, HbA1c, hypertension and cardiovascular disease. Further analyses detected an association between loneliness and type 2 diabetes onset (HR 1.41; 95% CI 1.04, 1.90; p = 0.027), independent of depressive symptoms, living alone and social isolation. Living alone and social isolation were not significantly associated with type 2 diabetes onset. CONCLUSIONS/INTERPRETATION: Loneliness is a risk factor for type 2 diabetes. The mechanisms underlying this relationship remain to be elucidated. Graphical abstract.

RESUMO

OF BACKGROUND DATA: Unspecified kidney donation (UKD) describes living donation of a kidney to a stranger. The practice is playing an increasingly important role within the transplant programme in the United Kingdom, where these donors are commonly used to trigger a chain of transplants; thereby amplifying the benefit derived from their donation. The initial reluctance to accept UKD was in part due to uncertainty about donor motivations and whether the practice was morally and ethically acceptable. OBJECTIVES: This article provides an overview of UKD and answers common questions regarding the ethical considerations, clinical assessment, and how UKD kidneys are used to maximize utility. Existing literature on outcomes after UKD is also discussed, along with current controversies. CONCLUSIONS: We believe UKD is an ethically acceptable practice which should continue to grow, despite its controversies. In our experience, these donors are primarily motivated by a desire to help others and utilization of their kidney as part of a sharing scheme means that many more people seek to benefit from their very generous donation.

RESUMO

BACKGROUND: Depression and anxiety symptoms (termed distress) are common among coronary heart disease (CHD) patients and associated with poor outcomes. Illness perceptions predict distinct outcome trajectories in other long-term conditions, yet it is not known how they relate to distress trajectories in CHD. PURPOSE: This study aimed to examine whether baseline illness perceptions are associated with distress symptom trajectories among primary care CHD patients. METHODS: This is a secondary analysis of 803 CHD patients from the UPBEAT-UK study, who completed the Hospital Anxiety and Depression Scale every 6 months for 3 years. Baseline assessments included the Brief Illness Perception Questionnaire. Using latent class growth analysis, Palacios et al. (2018) identified five distinct distress symptom trajectories ("stable low," "chronic high," "improving," "worsening," and "fluctuating") in this cohort. Adjusted multinomial logistic regression analyses were used to test the association between baseline illness perceptions and distress symptom trajectories. RESULTS: Compared with the stable low distress trajectory, stronger illness identity (odds ratio [OR] = 1.31, p < .01), higher perceived consequences (OR = 1.47, p < .01), illness-related emotion (OR = 1.66, p < .01), and illness concerns (OR = 1.36, p < .01) increased the odds of having chronic high distress. Stronger illness coherence (OR = 0.89, p < .05) and personal (OR = 0.77, p < .01) and treatment control (OR = 0.75, p < .01) reduced the odds of chronic high distress. Worsening distress symptoms were associated with weaker perceptions of treatment control, higher perceived consequences, and greater illness-related concerns and emotions. CONCLUSIONS: Illness perceptions of CHD are associated with distress symptom trajectories. Therapeutically modifying unhelpful illness perceptions in CHD patients who experience high levels of distress could potentially improve mental health outcomes.

RESUMO

BACKGROUND: Illness perceptions have been shown to predict a range of psychosocial and clinical outcomes in kidney disease; including quality of life, distress, treatment adherence and even survival in end-stage renal disease patients on dialysis. The aim of this study was to evaluate whether illness perceptions impact mortality in incident predialysis Chronic Kidney Disease (CKD) patients. METHODS: Over the study period between September 2015 and June 2019, a total of 200 participants with predialysis CKD were recruited from the Nephrology Outpatient's clinics at Mater Dei Hospital, Malta. The participants were followed up until June 2019, and the mortality information was collected. Cox proportional hazards models were used to examine the association between illness perceptions, and mortality risk, after adjustment for covariates including distress, kidney function, co-morbidity and psychological distress. RESULTS: Of the 200 cases available for analysis, there were 43 deaths. The mean survival time was 718.55 days (min. 3 days, max. 1297 days). The cumulative survival 1-year post the assessment of the Revised Illness Perceptions Questionnaire (IPQ-R) was 93%. Stronger identity beliefs (HR = 1.199, 95% CI: 1.060-1.357, p = 0.004), perceptions of a chronic timeline (HR = 1.065, 95% CI: 1.003-1.132, p = 0.041), personal control beliefs (HR = 0.845, 95% CI: 0.748-0.955, p = 0.007) and perceptions of control over the treatment (HR = 0.812, 95% CI: 0.725-0.909, p = 0.000) demonstrated a significant association with mortality after controlling covariates. In a subsequent saturated model, perceived identity, chronic timeline and treatment control perceptions remained significant predictors of mortality, together with serum albumin, comorbidities and urea. CONCLUSIONS: CKD patients' perceptions of treatment control, perceptions of a chronic timeline and perceived illness identity predict survival independently of clinical prognostic factors, including kidney function and co-morbidity. Illness perceptions are important and potentially modifiable risk factors in CKD. Further studies are required to test whether the assessment and the implementation of psychological interventions aimed to modify maladaptive illness perceptions influence clinical outcomes in CKD.

RESUMO

OBJECTIVES: To explore the evidence for cognitive heuristics or "rules of thumb" used within patients' reports of symptom appraisal and decisions to seek help for symptoms of cancer. METHODS: A secondary analysis of interviews from existing studies that explored symptom appraisal in patients who had sought help for potential symptoms of cancer. Transcripts from n = 50 in-depth interviews with patients referred with symptoms suspicious of cancer (pancreas, colorectal, oral, lung, melanoma, breast, and prostate) were re-analysed using a deductive thematic approach underpinned by the heuristics outlined in the Common Sense Model of Illness Self-regulation as set within the Model of Pathways to Treatment. RESULTS: The most dominant heuristic in patient reports was the Rate of change rule (ie, symptoms that are worsening, increasing, or have a sudden onset [rather than improving, stable or decreasing in number] are more likely to indicate illness). There was also support for the Duration rule, Pattern rule, Chronology rule, Severity (of interference) rule, Age-illness rule, Novelty rule, Similarity rule, Location rule, and Optimistic bias rule. There was a lack of evidence for the Prevalence and Stress-illness rules. CONCLUSIONS: People do appear to use heuristics to guide their appraisal of symptoms and their perceived need for healthcare. Heuristics may be an important aspect underlying symptom misinterpretation, thus making them key targets for interventions. For instance, campaigns could tackle cognitive biases rather than focusing on specific symptom awareness. Myth-busting messages could highlight that intermittent, mild symptoms, and symptoms that are not worsening can be signs of a serious health problem.

RESUMO

BACKGROUND: Fatigue affects between 49% and 92% of dialysis patients with considerable repercussions on their functioning and quality of life. PURPOSE: To evaluate whether fatigue severity and its impact on functioning predict survival (all-cause mortality) and time to transplantation among in-centre haemodialysis patients. METHODS: As part of a prospective study of fatigue among in-centre haemodialysis patients, survival data were collected between April 2014 and August 2017. Fatigue severity was measured using the Chalder Fatigue Questionnaire (CFQ) and fatigue-related functional impairment using the Work and Social Adjustment Scale (WSAS). Sociodemographic, clinical, and psychological data were collected. The association between fatigue and outcomes was assessed using proportional hazard survival models, allowing for competing risks, and discrete-time survival models. All models were adjusted for relevant risk factors. RESULTS: The sample consisted of 174 haemodialysis patients. There were 37 deaths and 31 transplantations over 3 years. At 1,095 days (36 months), cumulative survival was 70.5% and the cumulative transplantation rate was 22.2%. In unadjusted models, fatigue was significantly associated with an increased risk of death (CFQ-continuous SHR = 1.06, 95% CI: 1.02 to 1.11; CFQ-dichotomous SHR = 2.18, 95% CI: 1.11 to 4.31; WSAS SHR = 1.03, 95% CI: 1.01 to 1.05) and decreased likelihood of transplantation (CFQ-continuous SHR = 0.92, 95% CI: 0.87 to 0.98; CFQ-dichotomous SHR = 0.33, 95% CI: 0.15 to 0.75; WSAS SHR = 0.96, 95% CI: 0.93 to 0.99). However, these associations ceased to be significant after controlling for covariates. CONCLUSIONS: Fatigue was predictive of an increased risk of death and decreased likelihood of transplantation among patients, possibly through distress, impaired functioning, and its consequences, rather than clinical and inflammatory markers.

RESUMO

Depression is undisputedly common among individuals with End-Stage Kidney Failure and associated with adverse outcomes. It is well recognized that effective treatments for depression are needed within routine dialysis care. But, are we any closer to successfully treating depression in dialysis patients? We consider this question here with respect to two common treatments, antidepressant medication and cognitive behavioural therapy (CBT). Currently, there are limited data from randomized placebo-controlled trials regarding the acceptability and efficacy of antidepressants. CBT trials appear to show more consistent treatment effects, albeit the feasibility of routine delivery remains unknown. No studies in dialysis patients has evaluated the combined effects of CBT with antidepressants. There is a need to consider pragmatic depression treatment trials in dialysis patients in order to increase study recruitment in order to have more reliable data from which to evaluate the evidence base. Furthermore, we need to understand why treatments work, and for whom do they work? Lastly, addressing issues surrounding treatment acceptability and implementation as part of regular care remain as key challenges that require attention if we are to improve the mental health of individuals on dialysis.

RESUMO

Public health guidelines recommend women establish and maintain exclusive breastfeeding to 6 months postpartum. Women with a body mass index (BMI, kg/m2 ) in the overweight or obese range are less likely to initiate and continue breastfeeding than healthy weight women. Evidence for psychological mechanisms of this association using validated methods of measurement is limited, but factors such as attitudes and intentions for infant feeding are implicated. This study aimed to investigate the associations between maternal BMI, antenatal attitudes and intentions for infant feeding, and subsequent breastfeeding practices. A total of N = 128 women completed an online questionnaire antenatally, and n = 48 were followed-up in the first month postpartum. Validated measures of intentions (Infant Feeding Intentions Scale) and attitudes (Iowa Infant Feeding Attitude Scale) for infant feeding were used. One-way analysis of variance and multivariate regression analyses assessed study objectives. Infant feeding attitudes (p = .327) and intentions (p = .254) were similar among healthy weight, overweight, and obese women and did not differ significantly. In adjusted regression models, only intentions significantly predicted early breastfeeding behaviour (p = .036; AR2  = .301). Missing data analysis revealed no significant differences in the profile of completing versus noncompleting women. Evidence suggests postnatal factors contribute significantly to lower breastfeeding rates in cohorts of women with overweight or obese BMIs. Further investigations should consider using theory and methods from behavioural science to longitudinally investigate modifiable mechanisms of action responsible for lower breastfeeding rates among overweight and obese women to inform practices that support prolonged breastfeeding.

RESUMO

Background: Depression is common in haemodialysis (HD) patients and associated with poor outcomes. Purpose: To evaluate whether depression symptoms predict survival and transplantation in a large sample of haemodialysis patients using cause-specific survival models. Methods: Survival data was collected between April 2013 and November 2015, as part of the screening phase of a multicentre randomised placebo-controlled trial of sertraline in HD patients. Depression was measured using the Beck Depression Inventory-II (BDI-II) and the Patient Health Questionnaire-9 (PHQ-9). Demographic and clinical data were collected via a self-report questionnaire and medical records. Competing risk survival analysis involved cause-specific and subdistribution hazard survival models. All models were adjusted for appropriate covariates including co-morbidity and C-reactive protein (CRP) in a subanalysis. Results: Of 707 cases available for analysis, there were 148 deaths. The mean survival time was 787.5 days. Cumulative survival at 12 months was 88.5%. During the study follow-up period, there were 92 transplants. The cumulative transplant event rate at 12 months was 7.8%. In separate adjusted models, depression symptoms predicted mortality (BDI-II HR = 1.03 95% CI 1.01, 1.04; PHQ-9 HR = 1.04 95% CI 1.01, 1.06). With respect to screening cut-off scores, a PHQ-9 ≥ 10 was associated with mortality (HR = 1.51 95% CI 1.01, 2.19) but not a BDI-II ≥ 16. Depression symptoms were not associated with time to transplantation in either cause-specific or subdistribution model. Conclusions: Consistent with past findings in HD patients, depression symptoms predicted survival but were not associated with kidney transplantation. Suitable treatments for depression need further evaluation, and their impact upon quality of life and clinical outcomes determined. Trial Registration Number: (ISRCTN06146268).

RESUMO

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterised by unpredictable bowel symptoms. These can be difficult to manage, consequently impacting quality of life (QoL). In addition, a strained doctor-patient relationship is independently reported in the qualitative literature. Given the doctor is often the first port of call for people with IBS, a difficult relationship may influence subsequent IBS management. Research suggests illness perceptions are important in determining IBS outcomes in therapy; however, their association with doctor-patient relationship and QoL is yet to be investigated. This exploratory study aimed to investigate the association between these constructs in IBS, as well as potential mediation by illness perceptions. Online questionnaires measuring doctor-patient relationship, illness perceptions, acceptance and QoL, were completed by 167 participants who reported an IBS diagnosis (144 female, mean age = 44.22 years, SD = 15.91 years). Bootstrapped pathway analysis was used to model the relationship and mediation effects. There was a significant positive correlation between patient-doctor relationship and QoL, r = .258, n = 167, p = .001. There was a significant indirect effect between doctor-patient relationship and QoL through illness coherence and acceptance (bootstrapped estimate = .058, 95%CI Lower-Upper = .02, .095, p = .002). No other indirect effects were observed in combination with good fit indices for the other illness perceptions. Findings suggest a doctor-patient relationship which fosters mutual understanding and helps patients make sense of symptoms, increases their ability to manage their IBS in a psychologically flexible manner, subsequently helping them maintain their QoL.

RESUMO

Living kidney donation (LKD) has become routine practice across the world as the gold standard treatment of end-stage renal failure. Whilst the physical risks and harms of LKD surgery are well documented, relatively little is known about psychosocial outcomes. The aim of this study was to determine whether it was possible to quantify the psychosocial impact of LKD. A prospective longitudinal study of 93 living kidney donors was performed. Data were collected preoperatively, and 3 and 12 months after donation. Questionnaires included 11 validated psychosocial outcome measures and questions specific to LKD. Over time, there was no significant change in wellbeing, life satisfaction, self-esteem, social comparison, distress, depression, stress, anxiety or social support at 3 or 12 months. Despite this, questions specific to LKD indicated that donors felt positively about donation, with low levels of regret. This study provides a thorough assessment of psychosocial outcomes after LKD over the first year. Donors felt positive about LKD although there was no evidence of any significant change in psychosocial outcomes. Despite no measurable psychosocial benefit after living kidney donation, there was also no evidence of harm.
