Norovirus passive surveillance as an alternative strategy for genetic diversity assessment in developing countries.

J Infect Public Health 2021 Jun 2;14(8):990-993. Epub 2021 Jun 2.

Laboratory of Viral Gastroenteritis, INEI-ANLIS "Dr. Carlos G. Malbrán", Av. Vélez Sársfield 563, Buenos Aires 1281, Argentina.

In developing countries, the acute gastroenteritis outbreaks submitted for viral testing are limited due to deficient surveillance programs. The aim of this study was to analyze a passive surveillance strategy for monitoring the molecular epidemiology of norovirus (NV) and counterbalance the genetic diversity data gap. Laboratory-confirmed rotavirus negative sporadic stool samples (N = 523) collected between 2010 and 2017 from children were selected from our archival collection and were tested for NV and sequencing was performed on the positive samples.

Enterohepatic species - clinical importance, host range, and zoonotic potential.

Crit Rev Microbiol 2021 Jun 21:1-34. Epub 2021 Jun 21.

Faculty of Sciences, Institute of Biochemistry and Microbiology, Universidad Austral de Chile, Valdivia, Chile.

The genus defined just over 30 years ago, is a highly diverse and fast-growing group of bacteria that are able to persistently colonize a wide range of animals. The members of this genus are subdivided into two groups with different ecological niches, associated pathologies, and phylogenetic relationships: the gastric (GH) and the enterohepatic (EHH) species. Although GH have been mostly studied, EHH species have become increasingly important as emerging human pathogens and potential zoonotic agents in the last years. Read More

Reverse genetic engineering of simian rotaviruses with temperature-sensitive lesions in VP1, VP2, and VP6.

Virus Res 2021 Jun 16:198488. Epub 2021 Jun 16.

Department of Biology, Wake Forest University, Winston-Salem, NC. Electronic address:

Rotaviruses are 11-segmented double-stranded RNA viruses and important causes of acute gastroenteritis in young children. To investigate the functions of specific viral proteins during the rotavirus lifecycle, temperature-sensitive (ts) mutants were previously created using a cultivatable simian strain (SA11) and chemical mutagenesis. These ts SA11 mutants replicate more efficiently at the permissive temperature of 31°C than at the non-permissive temperature of 39°C. Read More

Benefit- risk assessment of off-label drug use in children: the bravo framework.

Clin Pharmacol Ther 2021 Jun 18. Epub 2021 Jun 18.

Departments of Pharmacology and Toxicology, and Intensive Care, Radboud Institute Health Sciences, Radboud University Medical Center, Nijmegen, The Netherlands.

A drug is granted a license for use after a thorough assessment of risks and benefits based on high quality scientific proof of its efficacy and safety. Many drugs that are relevant to children are not licensed for use in this population implying that a thorough assessment of risks and benefits in the pediatric population has not been made at all, implying a negative risk-benefit balance in children or implying insufficient information to establish the risk-benefit balance. Use of drugs without positive assessment of risks and benefits exposes children to potential lack of efficacy, unknown toxicity and harm. Read More

West J Emerg Med 2021 May 7;22(3):603-607. Epub 2021 May 7.

Imperial College London, Department of Primary Care and Public Health, Global Digital Health Unit, London, United Kingdom.

Introduction: Emergency department (ED) attendances fell across the UK after the 'lockdown' introduced on 23rd March 2020 to limit the spread of coronavirus disease 2019 (COVID-19). We hypothesised that reductions would vary by patient age and disease type. We examined pre- and in-lockdown ED attendances for two COVID-19 unrelated diagnoses: one likely to be affected by lockdown measures (gastroenteritis), and one likely to be unaffected (appendicitis).
