Abstract
A fixed-dose combination of ledipasvir and sofosbuvir (LDV/SOF) has been approved for treatment of HCV patients. We assessed the effect of LDV/SOF on patient-reported outcomes (PROs) in HIV-HCV-co-infected patients. Patient-reported outcomes data from HIV-HCV-co-infected patients who were treated with LDV/SOF for 12 weeks were collected as a part of a clinical trial (ION-4). Historical controls were HIV-HCV-co-infected patients treated with SOF and ribavirin (RBV) in PHOTON-1. We included 335 HIV-HCV-co-infected patients (SVR-12 in HCV genotype 1 was 96%) who received LDV/SOF, while 223 patients (SVR-12 in HCV genotype 1 was 76.3%) received SOF/RBV. During treatment, patients receiving LDV/SOF showed improvement in all of their PRO scores (+6.0% in activity/energy of CLDQ-HCV, +5.0% in fatigue score of FACIT-F, +6.8% in physical component of SF-36; all P < 0.0001) while those receiving SOF+RBV showed moderate decline in some of their PRO scores (-4.8% in physical functioning of SF-36, -4.4% in fatigue score of FACIT-F, both P < 0.001). Patients who achieved sustained virologic response with LDV/SOF also showed improvement of PROs (average +5.1%) while those treated with SOF/RBV showed less or no improvement (average +1.4%). In a multivariate analysis, in addition to depression and fatigue, receiving SOF+RBV (vs LDV/SOF) was independently associated with more PRO impairment during treatment (beta -6.1 to -12.1%, P < 0.001). Hence, HIV-HCV patients treated with LDV/SOF show significant improvement of their health-related quality of life and other patient-reported outcomes during treatment and after treatment cessation.

Abstract
Patients with HCV infection have reduced work productivity (WP), in terms of both presenteeism (impairment in work productivity while working) and absenteeism (productivity loss due to absence from work). The aim of this study was to identify clinical and patient-reported factors that are predictive of WP in HCV-infected patients. HCV-infected patients enrolled in clinical trials completed 3 PRO questionnaires (CLDQ-HCV, SF-36 and FACIT-F) and one work productivity (WPAI:SHP) questionnaire. In employed subjects, work productivity and its absenteeism and presenteeism components were calculated using WPAI:SHP instrument. Of 4121 HCV-infected patients with work productivity data, 2480 (60.2%) reported to be employed, and of those, 2190 had completed all PRO questionnaires before treatment initiation. Of the study cohort, 519/2190 (23.7%) had severe work impairment. In multiple linear regression analysis, work productivity was predicted by lower scores in activity/energy domain of CLDQ-HCV, physical well-being domain of FACIT-F, worry domain of CLDQ-HCV and role physical domain of SF-36 (all P < 0.0005). Furthermore, presenteeism was independently predicted by the activity/energy of CLDQ-HCV, physical well-being of FACIT-F, worry domain of CLDQ-HCV, role physical scale of SF-36 and fatigue scale of FACIT-F (P < 0.002). Finally, absenteeism was independently predicted by physical well-being scale of FACIT-F and role physical scale of SF-36 (all P < 0.002). Clinically, work productivity impairment was predicted by the presence of cirrhosis, anxiety, depression and clinically overt fatigue (P < 0.01). Thus, the most important drivers of WP in HCV are impairment of physical aspects of PROs and clinical history of depression, anxiety, fatigue and cirrhosis.

Abstract
BACKGROUND Interferon and ribavirin negatively impact health-related quality of life (HRQL) during treatment. AIM To compare the impact of interferon and/or ribavirin-containing regimens on HRQL to interferon- and ribavirin-free regimens. METHODS HRQL data from nine multinational phase 3 clinical trials of sofosbuvir (SOF)-based regimens with and without ledipasvir (LDV), pegylated interferon (IFN) or ribavirin (RBV) were used. The Short Form-36 (SF-36) HRQL questionnaire was administered to subjects prospectively at baseline, during treatment, and 12 and 24 weeks after treatment cessation. RESULTS A total of 3460 CH-C with SF-36 data were included (52.2 ± 10.3 years, 62.6% male, 73.6% treatment-naïve, 15.0% cirrhotic, 68.2% HCV genotype 1 and 20.1% genotype 3). Compared to baseline HRQL, at the end of treatment, severe HRQL decrements were noted in IFN + RBV ± SOF regimens (on average, -3.8 to -24.3 on a 0-100 scale for different HRQL domains), while moderate decrements were noted in SOF + RBV ± LDV (-2.8 to -8.6). In contrast, in SOF/LDV without RBV, HRQL improvements were noted during treatment (+2.3 to +5.2). By 12 weeks post-treatment, HRQL returned to baseline in IFN + RBV ± SOF (P > 0.05) and improved in all IFN-free arms (+2.6 to +7.8). In multivariate analysis, a lower end of treatment HRQL was associated with IFN + RBV + SOF and a higher end of treatment HRQL was associated with SOF/LDV. By post-treatment-12, SOF/LDV was additionally associated with higher mental health scores. These improvements in HRQL scores were maintained 24 weeks post-treatment. CONCLUSIONS Removing interferon and ribavirin has led to substantial improvement of health-related quality of life during treatment. This may result in better patient experience and higher adherence to treatment regimen.

Abstract
Although the incidence of new hepatitis C virus (HCV) infection has fallen, HCV-related complications are on the rise. Our aim was to assess and describe the 2005-2009 national inpatient mortality and resource utilization trends for patients with HCV. Data from the National Inpatient Sample (NIS) and the National Hospital Discharge Survey (NHDS) between 2005 and 2009 were analyzed. Included were all adult hospital discharges with HCV-related ICD-9 codes. Incremental hospital charge, in-hospital mortality and length of stay (LOS) were estimated using n = 1000 bootstrap replicates clustered by unique hospital identifier. A total of 123 939 (0.38%) discharges were related to HCV (primary or secondary diagnosis). In-hospital mortality increased from 1.7% (2005) to 2.6% (2009) (P < 0.001). Inflation-adjusted charges increased 2% annually from 2005 ($16 455 ± $570) to 2009 ($17 532 ± $1007, P = 0.029). This increase occurred despite the average LOS (5 days) and hospital costs ($6500) remaining stable while at the same time, hospital-to-hospital transfer admissions and disposition to home health care increased. HCV-related hepatocellular carcinoma predicted longer hospital stay and death; older age predicted death; and receiving more procedures predicted higher hospital costs. The percentage of patients with private insurance significantly decreased (4.7%), while government-sponsored insurance and uninsured increased by 2.5% and 2.1%, respectively (P < 0.05). Uninsured patients had a 49%-72% greater chance of dying during hospitalization than those with government-sponsored insurance. HCV-related inpatient mortality and resource utilization have increased. HCC was the largest predictor for mortality and resource utilization. These data are consistent with the rising clinical and societal burden of chronic hepatitis C in the United States.

Abstract
BACKGROUND Health utilities measure patients' preferences for a health state. AIM To assess health utilities for sofosbuvir-containing therapy for chronic hepatitis C. METHODS The SF-6D utility scores were derived from the SF-36 instrument administered at baseline, during and post-treatment to participants of the previously reported clinical trials of sofosbuvir. EQ-5D utility scores were also approximated from the SF-36 using a regression model. RESULTS Nine hundred and ninety-four patients were enrolled. Baseline SF-6D and EQ-5D scores were 0.66 ± 0.13 and 0.71 ± 0.22, respectively (the POSITRON trial), 0.71 ± 0.16 and 0.76 ± 0.23 (FISSION), 0.70 ± 0.14 and 0.75 ± 0.22 (FUSION), 0.72 ± 0.15 and 0.79 ± 0.22 (NEUTRINO). In all studies, SF-6D and EQ-5D scores were highly correlated with each other. (r = 0.83-0.87, P < 0.0001). After 12 weeks, patients receiving sofosbuvir + ribavirin (POSITRON) had similar utility scores to placebo (P > 0.05). Patients receiving 12 and 16 weeks of sofosbuvir + ribavirin (FUSION) had similar utility scores (P > 0.05). In FISSION, patients receiving sofosbuvir + ribavirin had significantly better utilities compared to patients receiving interferon + ribavirin (P < 0.001). Patients receiving sofosbuvir + ribavirin + interferon (NEUTRINO) had a decrease in utilities during treatment (SF-6D: from 0.72 to 0.62, EQ-5D: 0.79 to 0.65; P < 0.0001) similar to that observed in patients receiving pegylated interferon + ribavirin for 24 weeks in FISSION (0.72 to 0.62 and 0.77 to 0.65, respectively, P < 0.0001). After 12 weeks post-treatment, patients with SVR (FUSION) had improvement in SF-6D (+0.026 from baseline, P = 0.013) and EQ-5D (+0.043, P = 0.013). In multivariate analyses, baseline depression, anxiety, fatigue, insomnia and treatment-related anaemia were the most consistent predictors of utilities. CONCLUSIONS Patients' health utilities are minimally impacted by sofosbuvir + ribavirin treatment, as compared to interferon-based, therapy regardless of treatment duration. Clinical trials' numbers: NCT01542788 (POSITRON), NCT01497366 (FISSION), NCT01604850 (FUSION), NCT01641640 (NEUTRINO).

Abstract
BACKGROUND Type 2 diabetes is known to negatively impact the outcome of chronic liver disease. AIM To evaluate the impact of diabetes on the outcomes of liver transplants (LT). METHODS Study cohort included adults (>18 years) who received LT in the US between 1994 and 2013 (The Scientific Registry of Transplant Recipients). Pre- and post-transplant diabetes was recorded in patients with mortality follow-up. RESULTS We included 85 194 liver transplant recipients. Of those, 11.2% had history of pre-transplant diabetes. The most common indications for liver transplant were hepatitis C (36.4%), alcohol-related liver disease (20.6%), primary liver malignancy of unspecified aetiology (14.7%), cryptogenic cirrhosis (8.0%), hepatitis B (4.6%) and non-alcoholic steatohepatitis (3.9%). A total of 96.5% transplants were from deceased donors, and 7.9% donors had history of diabetes. During an average 6.5 years of follow-up, 31.3% recipients died and 8.8% had a graft failure. In multivariate survival analysis [at least 5 years of cohort follow-up (N = 35 870)], after adjustment for age, ethnicity, insurance type, history of chronic diseases, HCV infection and noncompliance, independent predictors of recipient mortality included the presence of pre-transplant diabetes [adjusted hazard ratio (95%CI) = 1.21 (1.12-1.30)] and developing diabetes post-transplant [1.06 (1.02-1.11)]. Donor's history of diabetes was also independently associated with higher mortality [1.10 (1.02-1.19)]. Furthermore, donor's history of diabetes was also associated with an increased the risk of liver graft failure [1.35 (1.24-1.47)]. CONCLUSIONS Presence of type 2 diabetes pre- and post-transplant, as well as presence of type 2 diabetes in the donors, are all associated with an increased risk of adverse post-transplant outcomes.

Abstract
BACKGROUND As baby boomers age, chronic hepatitis C (CHC) will become increasingly important in Medicare eligible group. AIM To evaluate trends in Medicare resource utilisation for CHC. METHODS We analysed the Medicare in-patient and out-patient data from 2005 to 2010. For each patient, all claims with CHC as a principal diagnosis were added up and yearly CHC-related spending was calculated. RESULTS A total of 48,880 out-patient claims for 21,655 CHC patients and 4884 hospital admission claims for 3092 patients were included. The number of in-patient (1.5-1.6/year) or out-patient (2.2-2.3/year) visits per patient did not change over time, nor did the demographic characteristics of the CHC population. The majority of this population was eligible for Medicare based on disability and the average number of diagnoses per in-patient claim (from 8.11 in 2005 to 8.60 in 2010) and per out-patient claim (from 2.18 in 2005 to 2.71 in 2010) increased (both P < 0.0001). The average total yearly spending per patient increased in the out-patient setting from $488 in 2005 to $584 in 2010 (P = 0.0132) and did not change in the in-patient setting (from $22,245 in 2005 to $23,383 in 2010, P = 0.14). In the multivariate analysis, the number of diagnoses and conditions per claim and the number of in-patient or out-patient procedures per year were the important independent predictors of increased resource utilisation. CONCLUSIONS Most Medicare beneficiaries with chronic hepatitis C who sought in-patient or out-patient care in 2005-2010 had received Medicare for disability. Although the total resource utilisation did not change, the proportion of patient's responsibility increased.

Abstract
BACKGROUND Electrical utility workers wear thick rubber gloves and often work in the cold. OBJECTIVE To document the challenge of working in the cold and the effectiveness of different glove/liner combinations in keeping workers' hands warm. METHODS Ten experienced male electrical utility employees worked in a controlled temperature walk-in chamber at -20 °C for 45 minutes for each of five glove conditions: standard five-finger rubber gloves with cotton liners and gauntlets, mitten style gloves, a prototype wool liner, and two heating options; glove or torso. Dependent measures were maximum grip force, skin temperatures, finger dexterity and sensitivity to touch, ratings of perceived effort and a rating of thermal sensation. RESULTS Participants' hand skin temperatures decreased, they perceived their hands to be much colder, their finger sensitivity decreased and their ratings of perceived exertion increased, however their performance did not degrade over the 45 minute trials. The mitten-style gloves showed a smaller drop in skin temperature for the 3rd and 5th digits (p< 0.05) than the other glove conditions. CONCLUSIONS Mitten style gloves kept workers' hands warmer than the standard five finger glove.

Abstract
Compared to the background population, people with epilepsy tend to have lower rates of education and employment, lower rates of marriage and childbearing, and lower overall socioeconomic status (SES). Disparities in epilepsy care based on sociodemographic factors have been observed in the literature, but it is not known whether any such disparities exist in the UK. The UK Epilepsy and Pregnancy Register is a prospective, observational, registration and follow-up study that was set up to determine the relative safety of all AEDs taken in pregnancy. Here, we report outcomes of registered pregnancies to women with epilepsy living in Scotland from December 1996 to June 2012, based on the degree of socioeconomic deprivation of their postcode area. The Scottish Index of Multiple Deprivation (SIMD) quintile scores from 2006 were used to determine degree of socioeconomic deprivation, and group 1 (most deprived) and group 5 (least deprived) were compared. There were 1526 pregnancies with complete outcome data to women living in Scotland. Of these, 1453 (95.1%) resulted in a live birth and 68 (4.7%) had a major congenital malformation (MCM). Postcodes could not be reliably identified or verified for an additional three women, who have been excluded from SIMD group analysis. Of all women included in this study, 32.4% were in group 1 and 13.2% in group 5. No difference in MCM rate was observed between the two groups (4.4% in group 1 compared to 4.7% in group 5, p=0.84). Women in group 5 were more likely to take preconceptual folic acid (56.8% compared to 14.0%, relative risk: 4.1; 95% CI: 3.1-5.2) and less likely to have generalized tonic-clonic seizures in pregnancy (13.0% compared to 29.2%, relative risk: 0.4; 95% CI: 0.3-0.7) than those in group 1. Women in group 5 were more likely to be on monotherapy regimens (80.2% compared to 65.9%, relative risk: 1.2; 95% CI: 1.1-1.3), less likely to be on valproate (19.5% compared to 28.0%, p=0.05), and more likely to be on lower doses of the drug (825.9mg/day compared to 1012.0mg/day, p=0.05) compared to those in group 1. Although no change in MCM rate was seen based on SES, differences in treatment between socioeconomic groups do exist, particularly for preconceptual folic acid consumption, AED regimen, and seizure frequency. Greater emphasis on the importance of preconceptual counseling, both to discuss AED choice and folic acid intake, would be of benefit, particularly to those living in areas of high socioeconomic deprivation, to improve equity of healthcare delivery for women with epilepsy in Scotland.
