Osteoporosis identification among previously undiagnosed individuals with vertebral fractures.

Because osteoporosis is under-recognized in patients with vertebral fractures, we evaluated characteristics associated with osteoporosis identification. Most patients with vertebral fractures did not receive evaluation or treatment for osteoporosis. Black, younger, and male participants were particularly unlikely to have had recognized osteoporosis, which could increase their risk of negative outcomes. INTRODUCTION: Vertebral fractures may be identified on imaging but fail to prompt evaluation for osteoporosis. Our objective was to evaluate characteristics associated with clinical osteoporosis recognition in patients who had vertebral fractures detected on their thoracolumbar spine imaging reports. METHODS: We prospectively identified individuals who received imaging of the lower spine at primary care clinics in 4 large healthcare systems who were eligible for osteoporosis screening and lacked indications of osteoporosis diagnoses or treatments in the prior year. We evaluated characteristics of participants with identified vertebral fractures that were associated with recognition of osteoporosis (diagnosis code in the health record; receipt of bone mineral density scans; and/or prescriptions for anti-osteoporotic medications). We used mixed models to estimate adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS: A total of 114,005 participants (47% female; mean age 65 (interquartile range: 57-72) years) were evaluated. Of the 8579 (7%) participants with vertebral fractures identified, 3784 (44%) had recognition of osteoporosis within the subsequent year. In adjusted regressions, Black participants (OR (95% CI): 0.74 (0.57, 0.97)), younger participants (age 50-60: 0.48 (0.42, 0.54); age 61-64: 0.70 (0.60, 0.81)), and males (0.39 (0.35, 0.43)) were less likely to have recognized osteoporosis compared to white participants, adults aged 65 + years, or females. CONCLUSION: Individuals with identified vertebral fractures commonly did not have recognition of osteoporosis within a year, particularly those who were younger, Black, or male. Providers and healthcare systems should consider efforts to improve evaluation of osteoporosis in patients with vertebral fractures.

Delineating sociodemographic, medical and quality of life factors associated with psychological distress in individuals with endometriosis.

STUDY QUESTION: What is the relationship between specific quality of life domains and depression, anxiety and stress in the endometriosis population? SUMMARY ANSWER: Psychosocial domains of quality of life, such as a perception of social support and self-image, are more strongly associated with depression, anxiety and stress than pain and medical factors. WHAT IS KNOWN ALREADY: Prior research indicates a high prevalence of anxiety and depression in individuals with endometriosis. Pain is thought to be critical in the development of psychological distress, however prior research has investigated this association without consideration of psychosocial quality of life domains such as social functioning, perceived social support and self-image. STUDY DESIGN, SIZE, DURATION: This study is a cross-sectional analysis of baseline data collected in a longitudinal study exploring psychological distress in endometriosis (n = 584). PARTICIPANTS/MATERIALS, SETTING, METHODS: Individuals living with endometriosis participated in this study and were recruited via online platforms of community organizations and support groups. Demographic and medical information concerning endometriosis treatment and diagnosis was self-reported. Psychological distress and quality of life was measured using the Depression, Anxiety and Stress Scale (DASS-21), Endometriosis Health Profile-30 (EHP-30) and the Short Form Survey (SF-36v2). A series of linear regression analyses explored the relationship between specific quality of life domains and the primary outcomes of depression, anxiety and stress. MAIN RESULTS AND THE ROLE OF CHANCE: Approximately half of the participants in this sample reported moderate to severe anxiety, depression and stress. Quality of life domains, particularly perceived social support, social functioning and self-image, were more strongly associated with psychological distress than medical or demographic factors. Pain was associated with anxiety, but not depression or stress. A greater number of endometriosis symptoms was only associated with depression. LIMITATIONS, REASONS FOR CAUTION: These data are cross-sectional and, therefore, causality cannot be inferred from this analysis. Information about endometriosis diagnosis and treatment was self-reported, and not verified against medical records. WIDER IMPLICATIONS OF THE FINDINGS: This study indicates that psychosocial factors may be more salient factors underlying depression, anxiety and stress in the endometriosis population than pain and medical factors. There is a need for interventions that target psychological distress in this population with a focus on the broader impact of endometriosis beyond pain and physical symptomatology. STUDY FUNDING/COMPETING INTEREST(S): This research was supported by the Research Training Program (RTP) Scholarship awarded to C.S.M. by Macquarie University.

Body image distress in head and neck cancer patients: what are we looking at?

PURPOSE: The aim of the present study is to investigate the prevalence of body image distress among head and neck cancer (HNC) patients after treatment and to examine its association with sociodemographic and clinical factors, health-related quality of life (HRQOL), HNC symptoms, sexuality, self-compassion, and psychological distress. Second, we aim to explore daily life experiences of HNC patients regarding body image. METHODS: A cross-sectional survey among HNC patients investigated the prevalence of body image distress based on the Body Image Scale. Multivariable logistic regression analysis was applied to study associations with sociodemographic and clinical factors, HRQOL (EORTC QLQ-C30), HNC symptoms (QLQ-HN43), sexuality (FSFI-6; IIEF-5), self-compassion (SCS-SF), and psychological distress (HADS). Qualitative data from a body image writing intervention was used to explore experiences in daily life related to body image. RESULTS: Body image distress was prevalent in 13-20% (depending on cut-off scores) of 233 HNC patients. Symptoms of depression (p < 0.001), younger age (p < 0.001), problems with social contact (p = 0.001), problems with wound healing (p = 0.013), and larger extent of surgery (p = 0.014) were associated with having body image distress. This model explained 67% of variance. Writing interventions of 40 HNC patients showed that negative body image experiences were related to appearance and function, with social functioning problems described most often. CONCLUSION: Prevalence of body image distress in HNC patients, using different cut-off scores, is 13-20%. Younger patients, patients after extensive surgery, and patients who had wound healing problems are most at risk. There is a significant association between body image distress and depressive symptoms and social functioning.

A text message intervention to support women's physical and mental health after breast cancer treatments (EMPOWER-SMS): a randomised controlled trial protocol.

BACKGROUND: Breast cancer is the most common cancer diagnosed in women worldwide. In developed countries, 80-90% of women will survive five years after diagnosis but the transition from hospital-based care to health self-management and self-efficacy can be difficult. Text messaging programs offer a simple and proven way to provide support to people with chronic diseases. This study aims to test the effectiveness of a text message support program at improving women's health self-efficacy, and physical and mental health outcomes after breast cancer treatments compared to usual care at 6-months and to understand the barriers and enablers to widespread implementation. METHODS: Single-blind randomised control trial (RCT; N = 160) comparing a text message support intervention to usual care in women with breast cancer (recruited from a large tertiary referral hospital in Sydney, Australia). The intervention group will receive a six-month text message support program, which consists of semi-personalised, supportive, lifestyle-focused text messages (4 messages/week) in addition to usual care. The control group will receive usual care without the text message program. Outcomes will be assessed at 6-months. The primary outcome is change in self-efficacy for managing chronic disease. Secondary outcomes include change in clinical outcomes (body mass index), lifestyle outcomes (physical activity levels, dietary behaviours), mood (depression and anxiety scales), quality of life, satisfaction with, and usefulness of the intervention. Analyses will be performed on the principle of intention-to-treat to examine differences between intervention and control groups. DISCUSSION: This study will test if a scalable and cost-effective text-messaging intervention is effective at improving women's health self-efficacy, as well as physical and mental health outcomes. Moreover, this study will provide essential preliminary data to bolster a large multicentre RCT to helpsupport breast cancer survivors throughout recovery and beyond.

Disparities in colostomy reversal after Hartmann's procedure for diverticulitis.

BACKGROUND: Hartmann's procedure for diverticulitis is a common procedure, with highly variable rates and timing of colostomy reversal. The aim of this study was to evaluate the impact of race and insurance coverage on reversal within 2 years of Hartmann's procedure for diverticulitis. METHODS: The Healthcare Cost and Utilization Project (HCUP) State Inpatient Database of five states (2007-2010) was queried for patients who had Hartmann's procedure in the setting of diverticulitis. Patients were grouped by race and insurance status, and multivariable adjustment was performed to evaluate rate and timing of colostomy takedown at 2 years. RESULTS: Among 11,019 patients who had Hartmann's procedure for diverticulitis, 6900 (69%) patients had colostomy reversal by 2 years, with a median time to reversal of 19 weeks. Compared to white patients with private insurance, combinations of black race and non-private insurance significantly reduced likelihood of colostomy reversal at 2 years across all combinations. Black patients without insurance had the lowest likelihood of reversal at 2 years (OR 0.27, 95% CI 0.14-0.51, p < 0.001). For patients who had colostomy reversal within 2 years, black patients without insurance had a significant delay in time to reversal (11 weeks, 95% CI 6-16, p < 0.001) compared to white patients with private insurance, and delays persisted across all other groups. CONCLUSIONS: Black patients and those without private insurance experienced significantly lower rates of, and delayed time to, colostomy reversal compared to white patients with private insurance. These disparities must be considered for allocation of resources in marginalized communities.

Factors associated with romantic relationship formation difficulties in women with breast cancer.

OBJECTIVE: Many un-partnered women report difficulty in forming romantic relationships after breast cancer, characterized by high dating-related anxiety and low perceived interpersonal competence. This study examined the relationship between poor body image (appearance investment and body dissatisfaction) and self-compassion, and women's ability to form romantic relationships post-breast cancer. METHODS: Women (N = 152) diagnosed with breast cancer, who were either un-partnered and expressed interest in romantic dating, or who had commenced a relationship post-diagnosis, completed an online survey. Assessments included the Interpersonal Competence Questionnaire, Dating Anxiety Scale, Self-compassion Scale, Appearance Schemas Inventory-Revised, Body Image Scale, and Experiences in Close Relationships Scale. Multiple regression analyses assessed the relationships between these variables. RESULTS: Partnered and un-partnered women differed in levels of dating anxiety, interpersonal competence, anxious attachment, and the self-evaluative salience facet of appearance investment. Analyses revealed a significant model for dating anxiety, with high self-evaluative salience, body image dissatisfaction, and attachment avoidance independently associated with this outcome. The model for interpersonal competence was also significant, with low attachment avoidance and high self-compassion independently associated with this outcome. CONCLUSIONS: Un-partnered women who place high importance on appearance for their self-worth and who report poor body image and low self-compassion are at risk of experiencing difficulties in forming new romantic relationships after breast cancer. Future interventions should target these variables to facilitate romantic dating during cancer survivorship.

The efficacy of commercial tooth storage media for maintaining the viability of human periodontal ligament fibroblasts.

AIM: To evaluate Save-A-Tooth (SAT), EMT Toothsaver (EMT) and Hank's Balanced Salt Solution (HBSS) for their influence on the viability and proliferative capacity of human periodontal ligament fibroblasts (HPDLFs). METHODOLOGY: Primary HPDLFs were seeded into 96-well cell culture plates and exposed to SAT, EMT, HBSS and water (negative control) for 0.5, 1, 3, 6, 12 and 24 h at room temperature (22 °C). After each exposure time, cell viability was measured through quantifying adenosine triphosphate (ATP) using a luminescent dye. The proliferative capacity was also quantified using the PrestoBlue assay after 12 or 24 h storage in each medium. The data were analysed statistically by two-way anova and post hoc Least Significant Difference (LSD) test (P < 0.05). The morphology of the cells after 12 h storage was also investigated through live/dead viability/cytotoxicity kit together with fluorescence microscopy. RESULTS: There was no significant difference in cell viability amongst HBSS, SAT and EMT groups up to 6 h. SAT was effective in maintaining cell viability only up to 12 h and then became detrimental to HPDLF; after 24 h, the effectiveness of SAT in maintaining cell viability was similar to that of water (P > 0.05). Amongst all the media, only EMT could maintain the proliferative capacity of HPDLFs significantly higher than the negative control, that is water (P < 0.05) after 24 h storage. CONCLUSION: EMT maintained the proliferative capacity of HPDLFs after 24 h storage.

Understanding and managing fish populations: keeping the toolbox fit for purpose.

Wild fish populations are currently experiencing unprecedented pressures, which are projected to intensify in the coming decades. Developing a thorough understanding of the influences of both biotic and abiotic factors on fish populations is a salient issue in contemporary fish conservation and management. During the 50th Anniversary Symposium of The Fisheries Society of the British Isles at the University of Exeter, UK, in July 2017, scientists from diverse research backgrounds gathered to discuss key topics under the broad umbrella of 'Understanding Fish Populations'. Below, the output of one such discussion group is detailed, focusing on tools used to investigate natural fish populations. Five main groups of approaches were identified: tagging and telemetry; molecular tools; survey tools; statistical and modelling tools; tissue analyses. The appraisal covered current challenges and potential solutions for each of these topics. In addition, three key themes were identified as applicable across all tool-based applications. These included data management, public engagement, and fisheries policy and governance. The continued innovation of tools and capacity to integrate interdisciplinary approaches into the future assessment and management of fish populations is highlighted as an important focus for the next 50 years of fisheries research.

Body image and psychological distress in nipple-sparing mastectomy: the roles of self-compassion and appearance investment.

OBJECTIVE: Women with breast cancer face threats to body image following surgery. Nipple-sparing mastectomy with immediate breast reconstruction (NSM + IBR) may minimise body image disturbance as this preserves the woman's skin and areola complex. We assessed levels of body image disturbance and psychological distress in women undergoing NSM + IBR. To further understand the body image-distress relationship, we investigated the potential moderating effect of self-compassion and appearance investment on this relationship. METHODS: Women diagnosed with breast cancer (N = 75) who had undergone NSM + IBR completed online questionnaires including the Body Image Scale, general (Depression, Anxiety and Stress Scales) and cancer-specific (Impact of Event Scale) psychological distress and Self-Compassion Scale and Appearance Schemas Inventory - Revised. RESULTS: Mean general and cancer-specific psychological distress scores were within normal ranges, and body image disturbance was moderately low. Body image was positively correlated with depression, stress, Impact of Event Scale scores and appearance investment and negatively correlated with self-compassion. MANCOVA analyses indicated a significant moderating effect of self-compassion and appearance investment on the body image disturbance-distress relationship (for depression, stress and intrusion), such that participants with high self-compassion and low appearance investment experienced lower distress than individuals with low self-compassion and high appearance investment. CONCLUSIONS: Moderately low levels of psychological distress and body image disturbance suggest NSM + IBR may minimise adverse psychological impacts of mastectomy. Increased body image disturbance was associated with psychological distress and moderated by self-compassion and appearance investment, suggesting a potential role for these characteristics as the focus of psychological interventions to minimise the negative impacts of mastectomy.

Viral dynamic modelling of Hepatitis C and resistance-associated variants in haemophiliacs.

AIM: Chronic hepatitis C virus (HCV) infection is an important source of morbidity and mortality among haemophiliacs. Limited data are available regarding treatment intervention using direct-acting antivirals (DAAs) and theoretical concerns regarding accumulation of drug-associated resistance variants (RAVs) remain. We conducted a pilot study of treatment with telaprevir/pegylated interferon-alfa/ribavirin to evaluate treatment response and the role of lead-in DAA therapy on mutational selection of resistance variants. METHODS: Ultra-deep sequence analysis was performed at baseline, 48 hours and 168 hours after treatment initiation. RESULTS: No dominant RAVs were identified at baseline, but low-level RAVs were noted at baseline in all subjects. Viral dynamic models were used to assess treatment responses. The efficacy parameter (Ɛ) for lead-in ranged from 0 to 0.9745 (mean = 0.514). Subsequent addition of telaprevir resulted in a mean efficacy of more than 0.999. This was comparable to subjects who started all three medications simultaneously. A total of 80% achieved SVR. While rapid shifts in the RAV population following DAA initiation were observed, treatment failure associated with A156V was observed in only one patient. Adverse event profiles were similar to that observed in non-haemophilia cohorts. There was no evidence of factor inhibitor formation. There was no evidence that lead-in provided benefit in terms of response efficacy. CONCLUSION: These data support DAA-based therapy in those with inherited bleeding disorders.

Virologic response and haematologic toxicity of boceprevir- and telaprevir-containing regimens in actual clinical settings.

Effectiveness, safety and tolerability of boceprevir (BOC) and telaprevir (TPV) in actual clinical settings remain unknown. We determined rates of sustained virologic response (SVR) and haematologic adverse effects among persons treated with BOC- or TPV-containing regimens, compared with pegylated interferon/ribavirin (PEG/RBV). Using an established cohort of hepatitis C virus (HCV)-infected persons, Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES), we identified those treated with a BOC- or TPV-containing regimen and HCV genotype 1-infected controls treated with PEG/RBV. We excluded those with HIV coinfection and missing HCV RNA values to determine SVR. Primary endpoints were SVR (undetectable HCV RNA ≥12 weeks after treatment completion) and haematologic toxicity (grade 3/4 anaemia, neutropenia and thrombocytopenia). We evaluated 2288 persons on BOC-, 409 on TPV-containing regimen and 6308 on PEG/RBV. Among these groups, respectively, 31%, 43% and 9% were treatment-experienced; 17%, 37% and 14% had baseline cirrhosis; 63%, 54% and 48% were genotype 1a. SVR rates among noncirrhotics were as follows: treatment naïve: 65% (BOC), 67% (TPV) and 31% (PEG/RBV); treatment experienced: 57% (BOC), 54% (TPV) and 13% (PEG/RBV); (P-value not significant for BOC vs TPV; P < 0.0001 for BOC or TPV vs PEG/RBV). Haematologic toxicities among BOC-, TPV- and PEG/RBV-treated groups were as follows: grade 3/4 anaemia 7%, 11% and 3%; grade 4 thrombocytopenia 2.2%, 5.4% and 1.7%; grade 4 neutropenia 8.2%, 5.6% and 3.4%. SVR rates are higher and closer to those reported in pivotal clinical trials among BOC- and TPV-treated persons compared with PEG/RBV-treated persons. Haematologic adverse events are frequent, but severe toxicity is uncommon.

Development, validation and initial outcomes of a questionnaire to examine human factors in postgraduate surgical objective structured clinical examinations.

BACKGROUND: Human factors including stress, repetition, burnout and fatigue are associated with possible sources of error. Objective structured clinical examinations (OSCEs), where examiners concentrate for long periods, would benefit from a human factors approach to see whether these factors affect consistency of examiner behaviour, attitude and marking. Little has been published for OSCEs, in part due to the lack of a validated tool for collecting data in this setting. METHODS: A 46-item questionnaire was developed based on the Human Factors Analysis and Classification System (HFACS) domains and completed by examiners in the Intercollegiate Membership of the Royal College of Surgeons (MRCS) examination. To refine the questionnaire, an initial analysis focused on response patterns of each item. Cronbach's α was used to assess internal consistency, and a factor analysis was performed to uncover different domains emerging from the data. RESULTS: A total of 108 examiners completed the questionnaire (90·0 per cent response rate). The questionnaire, refined to 38 items based on an initial analysis of response patterns, showed good reliability for internal consistency (Cronbach's α = 0·76) and test-retest reliability (r = 0·85, n = 48, P < 0·001). Four factors had a close themed resemblance to the original HFACS domains, but were associated with different items, suggesting that the four human-factor domains might be linked to different behaviours and attitudes in an examination setting. Analyses according to sex, professional background and experience highlighted additional stress levels in examiners from one of the surgical Royal Colleges (P <0·001), matching evidence from the situation in that College at the time of this study. CONCLUSION: The recognition and further investigation of human factors in OSCEs is needed to improve examiner experience and behaviour in order to influence delivery, candidate experience and quality assurance of these examinations.

Rumination, psychological distress and post-traumatic growth in women diagnosed with breast cancer.

OBJECTIVE: Rumination, the repetitive and recursive rehearsal of cognitive content, has been linked to depression and anxiety in physically well populations, and to post-traumatic growth (PTG) in physical illness populations. Women diagnosed with breast cancer may experience both psychological distress and PTG. As rumination may influence outcomes through distinct pathways, this study investigated the association of intrusion, brooding and instrumental subcomponents of rumination with psychological distress and PTG in the breast cancer context. METHODS: Women diagnosed with primary breast cancer (n = 185), mean age 55.98 years (SD = 9.26), completed an online survey including the Multi-dimensional Rumination in Illness Scale, Depression Anxiety and Stress Scales, Post-traumatic Growth Inventory, Medical Outcomes Social Support Survey, demographic and health-related questions. RESULTS: As predicted, regression analyses indicated that brooding was positively related to depression, anxiety and stress, but was also negatively related to the PTG dimensions of new possibilities and spiritual growth. Partially supporting the study hypotheses, intrusion was positively associated with stress and the PTG of relating to others and new possibilities. As hypothesised, instrumental rumination was positively associated with all five dimensions of PTG. CONCLUSIONS: Rumination is a key consideration in both positive and negative psychological responses of women diagnosed with breast cancer. Associations of specific components of rumination with varying psychological outcomes suggest differential paths by which the specific subcomponents of rumination exert this influence.

Validation of the Croatian and Lebanese Revised Illness Perception Questionnaires for Healthy People (IPQ-RH).

The absence of Croatian- and Arabic-language measures to assess illness representations has contributed to lack of research among Croatian and Lebanese populations. Utilising the robust confirmatory factor analysis (CFA) approach, this study aimed to validate Croatian and Arabic versions of the Revised Illness Perception Questionnaire for Healthy People (IPQ-RH) in the breast and cervical cancer contexts, and compared these illness perceptions among Croatian and Lebanese women living in Australia. Forward and back-translated versions of the IPQ-RH were administered in Croatian to Croatian-born (n = 238), and Arabic to Lebanese-born (n = 240) women. The IPQ-RH illness perceptions were assessed for each cancer type, and the Negative Affect (NA) subscale of the Positive and Negative Affect Schedule (PANAS) assessed discriminant validity. The CFA method demonstrated acceptable models across the Croatian and Lebanese IPQ-RH measures. The internal reliabilities for the IPQ-RH subscales were adequate and the subscales had low correlations with the NA subscale of the PANAS, indicating that the IPQ-RH measures are largely distinguishable from negative affective dispositions. These findings demonstrate that the Croatian and Lebanese IPQ-RH breast and cervical cancer measures have a factor structure similar to the originally developed IPQ-RH scale and provide further support for the theoretically developed illness representations.

Hepatitis E infection in HIV-infected liver and kidney transplant candidates.

Hepatitis E virus (HEV) has been reported to cause acute and chronic hepatitis in those with HIV infection and among solid organ transplant recipients in Europe. Limited data indicate that HEV is endemic in the United States, but the prevalence and significance of HEV infection among those with HIV and awaiting solid organ transplantation is unknown. We evaluated anti-HEV IgM and IgG antibodies and HEV RNA in 166 HIV-infected solid organ transplant candidates enrolled in the NIH HIV-Transplant Cohort. Overall prevalence of anti-HEV IgG approached 20% in both liver and renal transplant candidates. Evidence of recent infection was present in approximately 2% of liver transplant candidates and none of the kidney transplant candidates. HEV RNA was not detected in any patient. We conclude that markers of HEV infection are frequent among candidates for transplantation, but active, ongoing viremia is not seen. Evidence of recent infection (acute on chronic) liver disease was present in liver but not kidney recipients.

Hepatitis C virus NS3 mutations in haemophiliacs.

Haemophiliacs have high hepatitis C virus (HCV) exposure risk from blood products that did not undergo heat inactivation or disease-specific screening prior to 1987. Repeated exposure to infected factor concentrates predisposes haemophiliacs to higher likelihood of HCV from multiple sources. HIV coinfection could result in impaired clearance of less fit variants resulting in enrichment of quasispecies carrying resistance mutations. We postulated that haemophiliacs demonstrate increased prevalence of baseline signature mutations in the HCV NS3/4 serine protease coding domain. We examined the prevalence of putative HCV protease inhibitor mutations, mutations, subclassified into dominant mutations if changes conferred resistance, and minor variants not associated with drug resistance, in patients with haemophilia A or B, infected with HCV or HCV/HIV, prior to HCV PI exposure. A total of 151 subjects were evaluated, including 22 haemophiliacs and 129 non-haemophilic controls. Of the 58 mutations detected, 55 (95%) were resistance mutations and three (5%) were minor variants. Dominant mutations were detected in 10 (45.5%) haemophiliacs and in 43 (33.3%) controls (OR 1.67, 95% CI 0.67-4.16). There was no statistical difference in proportion of dominant mutations (P = 0.27) or minor variants (P = 0.47) between groups, despite adjustment for HIV status (P = 0.44). No significant differences in dominant or minor resistance mutations between haemophiliacs and non-haemophiliacs were observed. HIV presence or prior HAART exposure did not affect baseline distribution. We conclude that haemophiliacs are not at higher risk for pre-existing HCV PI mutations, and prospective studies of response to PI-based regimens with HCV activity are indicated.

Assessing rumination in response to illness: the development and validation of the Multidimensional Rumination in Illness Scale (MRIS).

The cognitive style of rumination extends existing cognitive models of emotional response to illness. In the absence of a specific measure, we developed the Multidimensional Rumination in Illness Scale (MRIS). In Study 1, an initial 60-item pool was tested, followed by confirmation of the factor structure in Study 2. In Study 1 participants (n = 185) completed the pilot version of the MRIS, then in Study 2 (n = 163) a reduced 41-item model was tested. Study 1: Exploratory factor analysis of a reduced 32-item scale indicated an initial four-factor solution for the MRIS (Intrusion, Brooding, Instrumental, Preventability), with satisfactory internal consistency and stable factor structure across gender. Study 2: Following scale revision, confirmatory factor analysis substantiated the adequacy of a three-factor MRIS structure, and good internal consistency, test-rest reliability, and concurrent and discriminant validity was demonstrated for the MRIS. The MRIS exhibited good psychometric properties in the current sample, providing a comprehensive assessment of the cognitive style of rumination in the context of physical illness.

Hepatitis C virus treatment and survival in patients with hepatitis C and human immunodeficiency virus co-infection and baseline anaemia.

The impact of pretreatment anaemia on survival in individuals with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection is not known. Moreover, HCV treatment is offered less frequently to individuals with anaemia, due to haematological side effects of the treatment regimen. This study aimed to determine the effect of HCV treatment on survival among HCV/HIV co-infected individuals with pretreatment anaemia using the Electronically Retrieved Cohort of HCV-Infected Veterans (ERCHIVES). Individuals with HCV/HIV co-infection were included in current analyses. Participants were considered treated if they were prescribed ≥ 4 weeks of HCV treatment. All-cause mortality data were obtained using record linkage. Survival analyses were performed using Cox proportional hazard models. Among 5000 HCV/HIV co-infected individuals, 1671 (33.4%) had pretreatment anaemia. In a follow-up period of up to 7 years (19,500 person-years), individuals with anaemia had significantly higher mortality rate compared with those without anaemia [144.2 (95% CI: 134.5-154.7) vs 47.5 (44.0-51.2) per 1000 person-years, respectively]. Among individuals with anaemia, HCV treatment was associated with significantly lower mortality rate [66.6 (44.3-100.2) vs 149.6 (139.2-160.5) per 1000 person-years, for treated vs untreated, respectively]. Treatment remained associated with substantial survival benefit after taking into account the effect of multiple comorbidities (hazards ratio: 0.34, 95% CI: 0.21-0.62). These data suggest that HCV/HIV co-infected individuals with pretreatment anaemia have significantly higher mortality compared with those without anaemia. HCV treatment is associated with substantial survival benefit in this group. Additional studies are needed to determine strategies to improve HCV treatment rates among this group.

Liver transplant outcomes in HIV+ haemophilic men.

Hepatitis C virus infection is the major cause of end-stage liver disease and the major indication for transplantation (OLTX), including among HIV-HCV co-infected individuals. The age of HCV acquisition differs between haemophilic and non-haemophilic candidates, which may affect liver disease outcomes. The purpose of the study was to compare rates of pre- and post-OLTX mortality between co-infected haemophilic and non-haemophilic subjects without hepatocellular cancer participating in the Solid Organ Transplantation in HIV Study (HIV-TR). Clinical variables included age, gender, race, liver disease aetiology, BMI, antiretroviral therapy, MELD score, CD4 + cell count, HIV RNA PCR and HCV RNA PCR. Time to transplant, rejection and death were determined. Of 104 HIV-HCV positive subjects enrolled, 34 (32.7%) underwent liver transplantation, including 7 of 15 (46.7%) haemophilic and 27 of 89 (30.3%) non-haemophilic candidates. Although haemophilic subjects were younger, median 41 vs. 47 years, P = 0.01, they were more likely than non-haemophilic subjects to die pre-OLTX, 5 (33.3%) vs. 13 (14.6%), P = 0.03, and reached MELD = 25 marginally faster, 0.01 vs. 0.7 years, P = 0.06. The groups did not differ in baseline BMI, CD4, detectable HIV RNA, detectable HCV RNA, time to post-OLTX death (P = 0.64), graft loss (P = 0.80), or treated rejection (P = 0.77). The rate of rejection was 14% vs. 36% at 1-year and 36% vs. 43% at 3-year, haemophilic vs. non-haemophilic subjects, respectively, and post-OLTX survival, 71% vs. 66% at 1-year and 38% vs. 53% at 3-year. Despite similar transplant outcomes, pretransplant mortality is higher among co-infected haemophilic than non-haemophilic candidates.
