Knowledge of hepatitis B and C prevalence, and numbers infected, are important for planning responses. Published HBsAg and anti-HCV prevalences for the 20 WHO European Region countries outside the ...EU/EFTA were extracted, to complement published data for the EU/EFTA. The general population prevalence of HBsAg (median 3·8%, mean 5·0%, seven countries) ranged from 1·3% (Ukraine) to 13% (Uzbekistan), and anti-HCV (median 2·3%, mean 3·8%, 10 countries) from 0·5% (Serbia, Tajikistan) to 13% (Uzbekistan). People who inject drugs had the highest prevalence of both infections (HBsAg: median 6·8%, mean 8·2%, 13 countries; anti-HCV: median 46%, mean 46%, 17 countries), and prevalence was also elevated in men who have sex with men and sex workers. Simple estimates indicated 13·3 million (1·8%) adults have HBsAg and 15·0 million (2·0%) HCV RNA in the WHO European Region; prevalences were higher outside the EU/EFTA countries. Efforts to prevent, diagnose, and treat these infections need to be maintained and improved.

Aims/hypothesis Fenofibrate caused an acute, sustained plasma creatinine increase in the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) and Action to Control Cardiovascular Risk in ...Diabetes (ACCORD) studies. We assessed fenofibrate's renal effects overall and in a FIELD washout sub-study. Methods Type 2 diabetic patients (n = 9,795) aged 50 to 75 years were randomly assigned to fenofibrate (n = 4,895) or placebo (n = 4,900) for 5 years, after 6 weeks fenofibrate run-in. Albuminuria (urinary albumin/creatinine ratio measured at baseline, year 2 and close-out) and estimated GFR, measured four to six monthly according to the Modification of Diet in Renal Disease Study, were pre-specified endpoints. Plasma creatinine was re-measured 8 weeks after treatment cessation at close-out (washout sub-study, n = 661). Analysis was by intention-to-treat. Results During fenofibrate run-in, plasma creatinine increased by 10.0 μmol/l (p < 0.001), but quickly reversed on placebo assignment. It remained higher on fenofibrate than on placebo, but the chronic rise was slower (1.62 vs 1.89 μmol/l annually, p = 0.01), with less estimated GFR loss (1.19 vs 2.03 ml min⁻¹ 1.73 m⁻² annually, p < 0.001). After washout, estimated GFR had fallen less from baseline on fenofibrate (1.9 ml min⁻¹ 1.73 m⁻², p = 0.065) than on placebo (6.9 ml min⁻¹ 1.73 m⁻², p < 0.001), sparing 5.0 ml min⁻¹ 1.73 m⁻² (95% CI 2.3-7.7, p < 0.001). Greater preservation of estimated GFR with fenofibrate was observed with baseline hypertriacylglycerolaemia (n = 169 vs 491 without) alone, or combined with low HDL-cholesterol (n = 140 vs 520 without) and reductions of ≥0.48 mmol/l in triacylglycerol over the active run-in period (pre-randomisation) (n = 356 vs 303 without). Fenofibrate reduced urine albumin concentrations and hence albumin/creatinine ratio by 24% vs 11% (p < 0.001; mean difference 14% 95% CI 9-18; p < 0.001), with 14% less progression and 18% more albuminuria regression (p < 0.001) than in participants on placebo. End-stage renal event frequency was similar (n = 21 vs 26, p = 0.48). Conclusions/interpretation Fenofibrate reduced albuminuria and slowed estimated GFR loss over 5 years, despite initially and reversibly increasing plasma creatinine. Fenofibrate may delay albuminuria and GFR impairment in type 2 diabetes patients. Confirmatory studies are merited.

Aims/hypothesis
Bilirubin has antioxidant and anti-inflammatory activities. Previous studies demonstrated that higher bilirubin levels were associated with reduced prevalence of peripheral arterial ...disease (PAD). However, the relationship between bilirubin and lower-limb amputation, a consequence of PAD, is currently unknown. We hypothesised that, in patients with type 2 diabetes, bilirubin concentrations may inversely associate with lower-limb amputation.
Methods
The relationship between baseline plasma total bilirubin levels and amputation events was analysed in 9,795 type 2 diabetic patients from the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study. The analysis plan was pre-specified. Lower-limb amputation was adjudicated blinded to treatment allocation. Relevant clinical and biochemical data were available for analyses. Amputation was a pre-specified tertiary endpoint.
Results
Bilirubin concentrations were significantly inversely associated with lower-limb amputation, with a greater than threefold risk gradient across levels. Individuals with lower bilirubin concentrations had a higher risk for first amputation (HR 1.38 per 5 μmol/l decrease in bilirubin concentration, 95% CI 1.07, 1.79,
p
= 0.013). The same association persisted after adjustment for baseline variables, including age, height, smoking status, γ-glutamyltransferase level, HbA
1c
, trial treatment allocation (placebo vs fenofibrate), as well as previous PAD, non-PAD cardiovascular disease, amputation or diabetic skin ulcer, neuropathy, nephropathy and diabetic retinopathy (HR 1.38 per 5 μmol/l decrease in bilirubin concentration, 95% CI 1.05, 1.81,
p
= 0.019).
Conclusions/interpretation
Our results identify a significant inverse relationship between bilirubin levels and total lower-limb amputation, driven by major amputation. Our data raise the hypothesis that bilirubin may protect against amputation in type 2 diabetes.
Background
While combination therapy with
nab
-paclitaxel/gemcitabine (
nab
-gem) is effective in pancreatic ductal adenocarcinoma (PDAC), its efficacy as perioperative chemotherapy is unknown. The ...primary objective of this multicenter, prospective, single-arm, phase II study was to determine whether neoadjuvant therapy with
nab
-gem was associated with higher complete resection rates (R0) in resectable PDAC, while the secondary objectives were to determine the utility of radiological assessment of response to preoperative chemotherapy and the safety and efficacy of
nab
-gem as perioperative therapy.
Methods
Patients were recruited from eight Australian sites, and 42 patients with radiologically defined resectable PDAC and an Eastern Cooperative Oncology Group performance status of 0–2 were enrolled. Participants received two cycles of preoperative
nab
-paclitaxel 125 mg/m
2
and gemcitabine 1000 mg/m
2
on days 1, 8, and 15 (28-day cycle) presurgery, and four cycles postoperatively. Early response to chemotherapy was measured with fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) scans on day 15.
Results
Preoperative
nab
-gem was completed by 93% of participants, but only 63% postoperatively. Thirty-six patients had surgery: 6 (17%) were unresectable, 15 (52%) had R0 (≥ 1 mm) resections, 14 (48%) had R1 (< 1 mm) resections, and 1 patient did not have PDAC. Median progression-free survival was 12.3 months and median overall survival (OS) was 23.5 months: R0 patients had an OS of 35 months versus 25.6 months for R1 patients after surgery. Seven patients had not progressed after 43 months.
Conclusions
The GAP trial demonstrated that perioperative
nab
-gem was tolerable. Although the primary endpoint of an 85% R0 rate was not met, the R0 rate was similar to trials using a > 1 mm R0 resection definition, and survival rates were comparable with recent adjuvant studies.
•Pain and fatigue are prevalent among adult survivors of childhood cancer.•Survivors often have unmet needs for information about managing pain and fatigue.•Unmet needs are related to fear of cancer ...recurrence.
Pain and fatigue are under-researched late effects of childhood cancer and its treatment, and may be interpreted by survivors as indicating cancer recurrence. Moreover, unmet information needs for managing pain and fatigue may be related to fear of cancer recurrence. We investigated the complex relationships between perceived cancer-related pain and fatigue, unmet information needs for managing pain and fatigue, and fear of cancer recurrence.
We surveyed 404 adult survivors of any form of childhood cancer (M = 16.82 years since treatment completion).
Many survivors reported perceived cancer-related pain (28.7%) and fatigue (40.3%), and anticipated future pain (19.3%) and fatigue (26.2%). These symptomologies were all related to unmet information needs for managing pain (18.8%) and fatigue (32.2%; all p’s<.001). Survivors reporting unmet information needs for managing pain (B = .48, 95% CI = 0.19-0.76, p = .001) and fatigue (B = .32, 95% CI = 0.06-0.52, p = .015) reported higher fear of cancer recurrence than survivors reporting no information needs.
Survivors often have unmet information needs for managing pain and fatigue, and these unmet needs are related to fear of cancer recurrence.
Long-term follow-up clinics should assess pain and fatigue. Information provision about pain and fatigue may be an important tool to help manage fear of cancer recurrence.
Summary
The burden of disease due to chronic viral hepatitis constitutes a global threat. In many Balkan and Mediterranean countries, the disease burden due to viral hepatitis remains largely ...unrecognized, including in high‐risk groups and migrants, because of a lack of reliable epidemiological data, suggesting the need for better and targeted surveillance for public health gains. In many countries, the burden of chronic liver disease due to hepatitis B and C is increasing due to ageing of unvaccinated populations and migration, and a probable increase in drug injecting. Targeted vaccination strategies for hepatitis B virus (HBV) among risk groups and harm reduction interventions at adequate scale and coverage for injecting drug users are needed. Transmission of HBV and hepatitis C virus (HCV) in healthcare settings and a higher prevalence of HBV and HCV among recipients of blood and blood products in the Balkan and North African countries highlight the need to implement and monitor universal precautions in these settings and use voluntary, nonremunerated, repeat donors. Progress in drug discovery has improved outcomes of treatment for both HBV and HCV, although access is limited by the high costs of these drugs and resources available for health care. Egypt, with the highest burden of hepatitis C in the world, provides treatment through its National Control Strategy. Addressing the burden of viral hepatitis in the Balkan and Mediterranean regions will require national commitments in the form of strategic plans, financial and human resources, normative guidance and technical support from regional agencies and research.

Human immunodeficiency virus (HIV) infection remains of major public health importance in Europe, with evidence of increasing transmission of HIV in several countries. This article provides an ...overview of HIV and acquired immunodeficiency syndrome (AIDS) surveillance data, and indicates that since 2000 the rate of newly reported cases of HIV per million population has almost doubled in Europe. In 2007, a total of 48,892 cases of HIV infection were reported from 49 of 53 countries in the Region, with the highest rates in Estonia, Ukraine, Portugal and the Republic of Moldova. In the European Union (EU) and European Free Trade Association (EFTA) countries, the predominant mode of transmission for HIV infection is sex between men followed by heterosexual contact. Injecting drug use is still the main mode of transmission in the eastern part of the WHO European region, while in the central part heterosexual contact is the predominant mode of transmission. In 2007, the reported number of AIDS cases diagnosed decreased in the Region overall, except in the eastern part. HIV/AIDS surveillance data are vital to monitor the trends of the HIV epidemic and evaluate public health responses.
The human immunodeficiency virus (HIV) epidemic among injecting drug users (IDUs) shows different developments in different parts of the European region. In the countries of the European Union (EU) ...and the European Free Trade Association (EFTA), the rates of reported newly diagnosed cases of HIV infection in IDUs are mostly at stable and low levels or in decline. In contrast, those rates increased in 2007 in many of the other (eastern) countries in the World Health Organization (WHO) European Region, suggesting that the HIV epidemic among IDUs in Europe is still growing. In countries or regions where indicators of HIV incidence show upward trends, existing prevention measures may be insufficient and in need of strengthening. In the EU/EFTA region the larger availability of harm reduction measures such as opioid substitution treatment and needle and syringe programmes may have played a key role in containing the epidemic among IDUs.
To describe changes in the injecting risk behaviour of injecting drug users (IDU) in London between 1990 and 1993.
Injecting risk behaviour was measured over 4 years (1990-1993) in a serial point HIV ...prevalence study of 2062 IDU recruited in both drug treatment and non-treatment community-based settings within greater London. The study used a structured questionnaire and common sampling and interview strategy developed by a World Health Organization technical group and implemented in 13 cities.
Log-linear models were used to assess patterns of change over years and of differences in injecting risk behaviour, including syringe sharing and syringe hygiene between 1990 and 1993. The log likelihood chi 2 statistic, G2, was used to test statistical significance. Changes in the mean values were assessed first using parametric tests assuming normality and the results were compared with Kruskal-Wallis (non-parametric) tests. Pearsons chi 2 was used to measure differences in frequency of sharing occasions and partner selectivity.
An overall reduction in injecting risk behaviour was observed during the first 2 years of this study, including a decline in syringe sharing (both accepting and passing on used syringes), the number of sharing partners and the frequency of sharing occasions. Most sharers restricted sharing to sexual partners and close friends. The majority of sharers reported always cleaning injecting equipment. Main source of sterile equipment was pharmacies and syringe exchanges. Indirect sharing (of spoons, filters, and by front- or backloading) was reported. Since 1991 there has been a stabilization in risk behaviour.
The data indicate that IDU in London have made positive reductions in risk behaviour. Levels of syringe sharing were substantially lower than those reported up to 1987 before AIDS awareness and the introduction of HIV prevention measures. The majority did not share syringes or confined their sharing to close friends and sexual partners, and if shared, cleaned their syringes. Continuation of indirect sharing indicates the need for more detailed prevention messages. While the initial decline in syringe-sharing rates may be attributed to the wide availability of sterile injecting equipment and other preventive measures, it may now be necessary to look beyond current intervention initiatives to develop interventions which seek to change the social etiquette of sharing and move towards the long-term maintenance of low levels of injecting risk behaviour.
