Medicines and the media: news reports of medicines recommended for government reimbursement in Australia
Conclusions: While there was no general trend to increased news reporting associated with PBAC meetings, some drugs did attract media attention. With more new and expensive drugs, decisions on public funding will become increasingly difficult. The media have an important role in enhancing public understanding of the issues around resource allocation. Specialist journalists, guidelines and checklists may help reporting.

Plasmacytoid dendritic cells promote rotavirus-induced human and murine B cell responses
B cell–dependent immunity to rotavirus, an important intestinal pathogen, plays a significant role in viral clearance and protects against reinfection. Human in vitro and murine in vivo models of rotavirus infection were used to delineate the role of primary plasmacytoid DCs (pDCs) in initiating B cell responses. Human pDCs were necessary and sufficient for B cell activation induced by rotavirus. Type I IFN recognition by B cells was essential for rotavirus-mediated B cell activation in vitro and murine pDCs and IFN-α/β–mediated B cell activation after in vivo intestinal rotavirus infection. Furth...

Genetic engineering of rotaviruses by reverse genetics
Abstract The rotavirus genome is composed of 11 gene segments of double‐stranded (ds)RNA. A recent breakthrough in the field of rotaviruses is the development of a reverse genetics system for generating recombinant rotaviruses possessing a gene segment derived from cloned cDNA. Although this approach is a helper virus‐driven system that is technically limited and gives low levels of recombinant viruses, it allows alteration of the rotavirus genome, thus contributing to our understanding of these medically important viruses. So far, this approach has successfully been applied to three of the 11 viral segments in our lab...

On the eve of the high-level Global Vaccines Summit hosted by Ban Ki-Moon, Bill Gates and General Sheikh Mohamed bin Zayed Al Nahyan, the Crown Prince of Abu Dhabi, Médecins Sans Frontières (MSF) warned that high prices for new vaccines could put developing countries in the precarious situation of not being able to afford to fully vaccinate their children in the future. “Urgent action is needed to address the skyrocketing price to vaccinate a child, which has risen by 2,700 per cent over the last decade,” said physician Manica Balasegaram, executive director of MSF’s Access Campaign. “Countries where we work wil...

Prevalence of Human Enteric Viruses and a Potential Indicator of Contamination in Shellfish in China
The objectives of this study were to quantify enteric viruses in shellfish along the Chinese coast and find an indicator of viral contamination in shellfish. One hundred sixty‐two samples were collected in August from 10 cities. Hepatitis A virus (HAV), norovirus (NV), rotavirus (RV), poliovirus (PV), astrovirus (AsV) and adenovirus (AdV) were detected by polymerase chain reaction (PCR) and confirmed by sequencing. The percentage of positive samples for each virus was as follows: HAV 5%, NV 12%, RV 7%, PV 15%, AsV 6% and AdV 9%. The six species of shellfish were contaminated with different viruses.

Prevalence and genetic diversity of norovirus among patients with acute diarrhea in Guatemala
Abstract Noroviruses (NoVs) are a leading cause of acute gastroenteritis outbreaks and sporadic cases of diarrhea in industrialized countries. To study the prevalence and genetic diversity of NoVs in Guatemala, stool specimens were collected from hospitalized and ambulatory patients presenting with diarrhea (≥3 loose or liquid stools in a 24‐hr period) who were enrolled in a prospective surveillance system in the Departments of Santa Rosa (October 2007 to August 2010) and Quetzaltenango (August 2009 to August 2010), Guatemala. Specimens were tested for rotavirus, enteric bacteria, and parasites by routine methods and f...

Effect of Rotavirus Vaccine on Diarrhea Mortality in Different Socioeconomic Regions of Mexico
In Mexico, substantial declines in childhood diarrhea deaths have been documented since the introduction of the rotavirus vaccine in 2007. However, there is concern of lower vaccine effectiveness in less developed regions of Mexico with higher diarrhea-related mortality. We documented significant and comparable declines across all 3 regions of Mexico with different levels of development, indicating equitable vaccine distribution to children with varying risk of mortality and reaffirming the beneficial effects of rotavirus vaccination against fatal diarrheal disease.

Evaluation of the Bioline Standard Diagnostics SD immunochromatographic norovirus detection kit using fecal specimens from Australian gastroenteritis incidents
Abstract: Human norovirus is a major cause of both sporadic cases and outbreaks of gastroenteritis and comprises two main genogroups (GI and GII) which, in turn, comprise a variety of genotypes. The current study examined the efficacy of the Bioline SD kit using fecal material from Australian gastroenteritis incidents. At best, the SD kit had a sensitivity of 62%. Freezing and thawing specimens before testing significantly improved sensitivity. The SD kit had a specificity of 98.6%. Genotype analysis (Open Reading Frame 2) indicated the SD kit could detect a range of genotypes and genotype variants including GI.1, GI.3, GI...

Viral Infections of Rabbits
Viral diseases of rabbits have been used historically to study oncogenesis (e.g. rabbit fibroma virus, cottontail rabbit papillomavirus) and biologically to control feral rabbit populations (e.g. myxoma virus). However, clinicians seeing pet rabbits in North America infrequently encounter viral diseases although myxomatosis may be seen occasionally. The situation is different in Europe and Australia, where myxomatosis and rabbit hemorrhagic disease are endemic. Advances in epidemiology and virology have led to detection of other lapine viruses that are now recognized as agents of emerging infectious diseases. Rabbit calici...

In this study, we report the prevalence and genotype of rotaviruses identified from children <5 years of age hospitalised with acute gastroenteritis from Nagercoil, Tamil Nadu from 2007-2010. From the 139 children included in the study, 71 samples (51%) were positive by ELISA and 65 samples were positive by PCR-based methods. G1P (44.6%) was the most commonly identified genotype. In addition, we report detection of rotavirus in two of three CSF samples from children with seizures. (Source: Indian Journal of Medical Microbiology)

The impact of Rotavirus mass vaccination on hospitalization rates, nosocomial Rotavirus gastroenteritis and secondary blood stream infections
Conclusions: UMV may have contributed to the significant decrease of RV-GE-associated hospitalizations, to a reduction in nosocomial RV infections and RV-associated morbidity due to secondary BSI and reduced direct hospitalization costs. The reduction in nosocomial cases is an important aspect considering severe disease courses in hospitalized patients with co-morbidities and death due to nosocomial RV-GE.

Abstract: In this paper we highlight several instances in which there is potential for novel utilization in the near future of relatively recently licenced vaccines, vaccines approaching licensure or vaccines already in established use. Specifically we discuss the potential for universal seasonal influenza immunization and the arrival of live attenuated intranasal vaccine which was licenced for use in children aged 2–17 years in Europe in 2010, the potential use of live oral rotavirus vaccines for infants, two of which have been available in Europe since 2006, pertussis, which despite availability and widespread use thro...

Vaccines are extremely powerful disease prevention agents and have the potential to save millions of lives. Tremendous scientific progress has been made in the past decade with several new vaccines licensed, including those to prevent pneumococcal and rotavirus disease—the two leading killers of young children in developing countries. Thanks to concerted efforts by stakeholders through the GAVI Alliance, many of these new vaccines are now accessible to the lowest-income countries and the children who live there. (Source: LANCET)

Circulating rotaviral RNA in children with rotavirus antigenemia
Conclusions: Antigenemia is present in a significant number of patients with rotavirus diarrhea. Rotavirus viremia was absent in the children with rotavirus diarrhea who participated in our study, and was not indicated by the presence of antigenemia. The significance of circulating rotavirus antigen and genomic dsRNA in serum of patients with diarrhea deserves further study. (Source: Journal of Negative Results in BioMedicine)
