Progress Toward Poliovirus Containment Implementation - Worldwide, 2019-2020.
Abstract Since 1988, when World Health Organization (WHO) Member States and partners launched the Global Polio Eradication Initiative, the number of wild poliovirus (WPV) cases has declined from 350,000 in 125 countries to 176 in only two countries in 2019 (1). The Global Commission for the Certification of Poliomyelitis Eradication (GCC) declared two of the three WPV types, type 2 (WPV2) and type 3 (WPV3), eradicated globally in 2015 and 2019, respectively (1). Wild poliovirus type 1 (WPV1) remains endemic in Afghanistan and Pakistan (1). Containment under strict biorisk management measures is vital to prevent re...

Contemporary circulating enterovirus D68 strains have acquired the capacity for viral entry and replication in human neuronal cells
Background: Enterovirus D68 (EV-D68) is a member of the Picornaviridae family of single-stranded positive-sense RNA viruses. EV-D68 infection has historically been associated with respiratory illnesses in humans. However, in the summers of 2014, 2016, and 2018 EV-D68 outbreaks coincided with a spike in polio-like acute flaccid myelitis (AFM) cases. This raised concerns that EV-D68 could be the causative agent of AFM during these recent outbreaks. (Source: International Journal of Infectious Diseases)

Supporting polio outbreak response through mathematical modelling
Background: Whilst wild polio outbreaks are becoming a distant memory, vaccine-derived poliovirus (VDPV) outbreaks are increasing in incidence. For many countries currently experiencing VDPV outbreaks (Philippines, Ghana, Indonesia, etc.) it has been many years since polio has been observed and the optimal location of vaccination campaigns are uncertain.

Expected Implications of Globally Coordinated Cessation of Serotype 3 Oral Poliovirus Vaccine (OPV) Before Serotype 1 OPV
AbstractGlobally coordinated cessation of all three serotypes of oral poliovirus vaccine (OPV) represents a critical part of a successful polio endgame, which the Global Polio Eradication Initiative (GPEI) plans to conduct in phases, with serotype 2 OPV cessation completed in mid 2016. Although in 2016 the GPEI expected to globally coordinate cessation of the remaining OPV serotypes (1 and 3) by 2021, continuing transmission of serotype 1 wild polioviruses to date makes those plans obsolete. With increasing time since the last reported polio case caused by serotype 3 wild poliovirus (in November 2012) leading to high confi...

The sixth revolution in pediatric vaccinology: immunoengineering and delivery systems.
Abstract Infection is the predominant cause of mortality in early life, and immunization is the most promising biomedical intervention to reduce this burden. However, very young infants fail to respond optimally to most vaccines currently in use, especially neonates. In 2005, Stanley Plotkin proposed that new delivery systems would spur a new revolution in pediatric vaccinology, just as attenuation, inactivation, cell culture of viruses, genetic engineering, and adjuvantation had done in preceding decades. Recent advances in the field of immunoengineering, which is evolving alongside vaccinology, have begun to inc...

Olga E. Ivanova Significantly divergent polioviruses (VDPV) derived from the oral poliovirus vaccine (OPV) from Sabin strains, like wild polioviruses, are capable of prolonged transmission and neuropathology. This is mainly shown for VDPV type 2. Here we describe a molecular-epidemiological investigation of a case of VDPV type 3 circulation leading to paralytic poliomyelitis in a child in an orphanage, where OPV has not been used. Samples of feces and blood serum from the patient and 52 contacts from the same orphanage were collected twice and investigated. The complete genome sequencing was performed for five poliov...

Positive Cytosolic 5-Nucleotidase 1A Antibodies in Motor Neuron Disease
Inclusion body myositis (IBM) is the most common acquired myopathy in adults older than 50 years. Muscle biopsy remains the gold standard for diagnosis. Recently described serum antibodies against cytosolic 5-nucleotidase 1A (cN1A) are considered highly specific for IBM. However, positive cN1A antibodies in diseases other than IBM are recently reported. We review 2 cases in which serum antibodies were positive but ancillary testing revealed motor neuron disease. A 68-year-old man presented with asymmetric quadriceps and handgrip weakness prompting concern for IBM. However, electromyography showed purely chronic neurogenic ...

[Travel vaccinations in rheumatic diseases : Specific considerations in children and adults].
r U Abstract Children and adults with rheumatic diseases (RD) have a higher risk to contract infections due to the underlying disease and the frequently necessary immunosuppressive treatment (IT). The quality of life of the majority of patients with RD has remarkably improved due to IT-related reduction of inflammation. Therefore, RD patients usually have an international travel behavior similar to healthy individuals. An investigation indicated that patients with RD and IT have lower travel vaccination rates and are often less well-prepared for their trip in comparison to healthy travelers, even when visitin...

The evolution of nerve transfers for spinal cord injury.
Abstract Spinal cord injury (SCI) often results in devastating effects on function and quality of life. The majority of SCIs occur in the cervical region with restoration of arm and hand function being the highest priority by patients. Current restoration strategies rely on maximizing and optimally redistributing residual muscle functions that remain under volitional control. The polio epidemic and World Wars led to the development and refinement of tendon transfers, which has long been the standard reconstructive approach for the upper extremity following SCI. However, the past few decades has seen the emergence ...
