Securing sustainable funding for viral hepatitis elimination plans

The majority of people infected with chronic hepatitis C virus (HCV) in the European Union (EU) remain undiagnosed and untreated. During recent years, immigration to EU has further increased HCV prevalence. It has been estimated that, out of the 4.2 million adults affected by HCV infection in the 31 EU/ European Economic Area (EEA) countries, as many as 580 000 are migrants. Additionally, HCV is highly prevalent and under addressed in Eastern Europe. In 2013, the introduction of highly effective treatments for HCV with direct‐acting antivirals created an unprecedented opportunity to cure almost all patients, reduce HCV transmission and eliminate the disease. However, in many settings, HCV elimination poses a serious challenge for countries’ health spending. On 6 June 2018, the Hepatitis B and C Public Policy Association held the 2nd EU HCV Policy summit. It was emphasized that key stakeholders should work collaboratively since only a few countries in the EU are on track to achieve HCV elimination by 2030. In particular, more effort is needed for universal screening. The micro‐elimination approach in specific populations is less complex and less costly than country‐wide elimination programmes and is an important first step in many settings. Preliminary data suggest that implementation of the World Health Organization (WHO) Global Health Sector Strategy on Viral Hepatitis can be cost saving. However, innovative financing mechanisms are needed to raise funds upfront for scaling up screening, treatment and harm reduction interventions that can lead to HCV elimination by 2030, the stated goal of the WHO.     

Timing of climate variability and grassland productivity

Future climates are forecast to include greater precipitation variability and more frequent heat waves, but the degree to which the timing of climate variability impacts ecosystems is uncertain. In a temperate, humid grassland, we examined the seasonal impacts of climate variability on 27 y of grass productivity. Drought and high-intensity precipitation reduced grass productivity only during a 110-d period, whereas high temperatures reduced productivity only during 25 d in July. The effects of drought and heat waves declined over the season and had no detectable impact on grass productivity in August. If these patterns are general across ecosystems, predictions of ecosystem response to climate change will have to account not only for the magnitude of climate variability but also for its timing.     

Community consultation in emergency neurotrauma research: results from a pre-protocol survey

Background

Uncertainty remains as to the role of decompressive craniectomy (DC) for primary evacuation of an acute subdural haematoma (ASDH). In 2011, a collaborative group of neurosurgeons, neuro-intensive care physicians and trial methodologists was formed in the UK with the aim of answering the following question: “What is the clinical- and cost-effectiveness of DC, in comparison to simple craniotomy for adult patients undergoing primary evacuation of an ASDH?” The proposed RESCUE-ASDH trial (Randomised Evaluation of Surgery with Craniectomy for patients Undergoing Evacuation of Acute Subdural Haematoma) is a multi-centre, pragmatic, parallel group randomised trial of DC versus simple craniotomy for adult head-injured patients with an ASDH. Clinical trials in the emergency setting face the problem that potential participants may be incapacitated and their next of kin initially unavailable. As a result, consent and enrolment of participants can often be difficult.

Method

In the current study, we aimed to assess public opinion regarding participation in the RESCUE-ASDH trial and acceptability of surrogate consent by conducting a pre-protocol community consultation survey.

Results

One hundred and seventy-one subjects completed the survey. Eighty-four percent of participants responded positively when asked if they would participate in the proposed trial. Ninety-six percent and 91 % answered positively when asked if they found surrogate consent by their next of kin and an independent doctor acceptable, respectively. None of the characteristics of the study population were found to affect the decision to participate or the acceptability of surrogate consent by the next of kin. Being religious showed a trend towards higher acceptability of surrogate consent by a doctor. Conversely, an education to degree level and above showed a trend towards reduced acceptability of surrogate consent by a doctor.

Conclusions

Our community consultation survey shows that the proposed trial is acceptable to the public. In addition, the results suggest high levels of acceptability of surrogate consent by next of kin or independent doctor amongst our community.     

Admission inflammatory markers and isolation of a causative organism in patients with spontaneous spinal infection

Introduction

The purpose of this study was to investigate the significance of the inflammatory markers on admission in the isolation of a causative pathogen in patients with spinal infection. Spinal infection is treated frequently at spinal units and can encompass a broad range of clinical entities. Its diagnosis is often delayed because of the difficulty of identifying the responsible pathogen.

Methods

Patients with spinal infection treated in our institution over a period of eight years were identified and their notes studied retrospectively. Admission C-reactive protein (CRP), white cell count (WCC) as well as co-morbidities and mode of pathogen identification were recorded. Overall, 96 patients were included in the study.

Results

The CRP levels on admission were correlated significantly with the overall potential for isolation of a pathogen (p<0.0001) and positive biopsy cultures (p=0.0016). Admission WCC levels were associated significantly with the overall potential for isolation of a pathogen (p=0.0003) and positive biopsy cultures (p=0.0023). Both CRP and WCC levels were significantly negatively correlated with the duration of the preceding symptoms (p=0.0003 and p<0.0001 respectively). Delay in presentation was significantly negatively correlated with organism isolation (p=0.0001). Multivariate analyses identified the delay in presentation as the strongest independent variable for organism isolation (p=0.014) in cases of spontaneous spinal infection when compared with the admission CRP level (p=0.031) and WCC (p=0.056).

Conclusions

In spontaneous spinal infection, delay in presentation is the strongest independent variable for organism isolation. High inflammatory marker levels on admission are a useful prognostic marker for the overall potential of isolating a causative organism either by blood cultures or by biopsy in patients with negative blood cultures. Furthermore, the admission inflammatory marker levels allow for treating surgeons to counsel their patients of the likelihood of achieving a positive microbiological yield from biopsy.     

Association between granzyme B and perforin I polymorphisms and allograft outcomes in Hispanic kidney transplant recipients

Granzyme B (GZMB) and perforin 1 gene (PRF1) are key effector molecules of cytotoxic T lymphocytes, in causing acute and chronic solid organ transplant rejection. In this study, we analyzed the impact of GZMB and PRF1 polymorphism on kidney allograft outcomes. In all, 527 de novo kidney Hispanic allograft recipients were genotyped for PRF1 (rs10999426, rs35947132) and GZMB (rs8192917, rs7144366). PRF1 (rs10999426, rs35947132) G alleles and GG genotypes were negatively associated with allograft rejection, demonstrating protection against allograft rejection (OR = 0.61, p = 0.005 for rs1099946; OR = 0.4, p = 0.01 for rs 35947132). On the other hand, the GA heterozygosity of PRF1 was found marginally associated with the rejection group (OR = 1.53, p = 0.05 for rs10999426; OR = 2.24, p = 0.07 for rs35947132). There was a significant increase in allograft survival in time period studied for the PRF1 (rs10999426) GG genotype, while the GA heterozygosity was associated with graft failure. We found no association for polymorphic markers in GZMB gene with allograft rejection. Survival was significantly improved for patients who were homozygous TT for the GZMB (rs8192917) (TT vs. CC/TT, p = 0.041). The result suggests that PRF1 and GZMB gene polymorphisms may determine the incidence of acute rejection or graft survival among Hispanic allograft recipients.     

Mesenteric lipodystrophy – An unusual intraabdominal mass

INTRODUCTIONWe report the case of a 21 year old female with underlying facial lipodystrophy who presented with left lower abdominal pain, weight gain and altered bowel habit.PRESENTATION OF CASESubsequent investigation showed a large (21 cm × 18 cm × 8 cm) intraabdominal mass. At laparotomy, it was completely excised and was seen to arise from the transverse mesocolon and following histology revealed it to be mesenteric lipodystrophy.DISCUSSIONMesenteric lipodystrophy is a rare clinical entity, and part of a spectrum of disorders of sclerosing mesenteritis. This is the first reported case in a patient with pre-existing facial lipodystrophy.CONCLUSIONHerein we describe a case of mesenteric lipodystrophy, discuss its management and review of the literature.
