This study aims to explore a possible silent circulation of wild and vaccine-derived polioviruses in departments of Colombia with polio vaccination coverage of below 80%. The study collected 52 samples of wastewater concentrated as a result of precipitation with polyethylene glycol and sodium chloride. The viral detection was carried out through isolation and the identification through neutralizat

BACKGROUND: An outbreak of acute hemorrhagic conjunctivitis occurred in Cuba in 2008 and 2009.OBJECTIVE: To determinate the etiological agent associated with the Cuban outbreaks of acute hemorrhagic conjunctivitis during 2008 and 2009.STUDY DESIGN: Conjunctival swabs and/or faecal samples from 382 patients with clinical diagnosis suggestive of acute hemorrhagic conjunctivitis were subject to viral

BACKGROUND: As part of an evaluation of strategies to make inactivated poliovirus vaccine (IPV) affordable for developing countries, we conducted a clinical trial of fractional doses of IPV in Cuba.METHODS: We compared the immunogenicity and reactogenicity of fractional-dose IPV (0.1 mL, or 1/5 of a full dose) given intradermally using a needle-free jet injector device compared with full doses giv

Good alternatives to the Impact Factor (IF) algorithm are needed. The Thomson IF represents a limited measure of the importance of an individual article because 80% of a journal's IF is determined by only the 20% of the papers published. In the past few years, several new indexes has been created to provide alternatives to the IF algorithm. These include the removal of self citations from the calc

Adenoviruses are common pathogens that are responsible for a wide variety of infectious syndromes. The objectives of this study were to identify and characterize members of different adenovirus species at the molecular level and to describe the correlation between viruses and clinical syndromes during a period of 4 years. Between 2002 and 2006, 45 of 512 respiratory specimens (8%) from patients wi

Myocarditis is caused frequently by viral infections of the myocardium. In the past, enteroviruses (EV) were considered the most common cause of myocarditis in all age groups. Other viruses that cause myocarditis are adenovirus and influenza viruses. Parvovirus B19 infection is associated sometimes with myocarditis. Members of the Herpesviridae family, cytomegalovirus (CMV), and human herpesvirus

BACKGROUND: The penetrance of type 1 diabetes mellitus (T1DM) in a genetically susceptible population is largely determined by environmental influences amongst which the human enteroviruses are prominent putative factors.AIM/HYPOTHESIS: The aim of this study was to determine the occurrence of enterovirus RNA in serum of children with type 1 diabetes at onset and ICA-positive subjects in a populati

Stool specimens collected from 1 515 healthy children following a mass vaccination campaign in Cuba were tested for poliovirus excretion using L20B cell lines. In spite of the selectivity of this cell line for polioviruses (117/129; 90.7%) some other nonpolio enteroviruses (12/129: 9.3%), such as coxsackie A virus types 4, 8 and 10, can grow in L20B cells.

OBJECTIVES: Implementing environmental surveillance for poliovirus circulating from wastewater.METHODS: Six wastewater samples were collected from each final site within a wastewater collection system in Armenia, Quindío. Virus was extracted and concentrated by a method using polyethylenglycol and sodium chloride as concentrating agent. Polioviruses were identified by polymerase chain reaction ass

Type 1 diabetes associated genes account for less than 50% of disease susceptibility. Human enteroviruses have been implicated as environmental factors that might trigger and/or accelerate this autoimmune disorder. We now report of a 12-year-old girl that developed pancreatic autoimmunity and type 1 diabetes after enteroviral infection. Diabetes-associated autoimmunity was evaluated by measurement

Samples of feces and sera obtained from 3-year-old children were studied to increase the knowledge about the circulations of virus vaccines during the massive campaigns. The use of the oral polio vaccine with schemes of massive campaigns allows the circulation of the virus vaccine 2 months after their completion. The use of continual vaccination schemes makes possible the circulation of the virus

This invited contribution is a reflection on my motivation for writing the book Leadership and Organization: A Philosophical Introduction (Spoelstra, 2018). The premise of the book is that popular leadership adjectives, e.g. ‘transformational’, ‘authentic’ and ‘servant’, are much more interesting than the corresponding leadership constructs suggest. The book claims that these popular leadership co

Fecal samples were weekly obtained from children under 3 years of age to isolate non-polio poliovirus and enterovirus and to expand the knowledge on circulation of vaccine-derived viruses during mass campaigns. The steady vaccination schedules allow the circulation of these viruses for long periods of time. The interference of non-polio enterovirus by vaccine poliovirus was demonstrated in childre

Background: The Swedish National Patient Registry (NPR) is a nationwide registry that is used extensively for epidemiological research. Using the NPR, we recently found a recurrent pregnancy loss (RPL) incidence of 650/100,000 (0.65%) pregnant women in Sweden. It is of great importance that the quality of the coding is good and reliable in order to use NPR data for research. To specifically study

AIMS/HYPOTHESIS: To determine whether the emergent infection by echovirus 16 that occurred in Cuba during the year 2000 was related to the presence of Type 1 diabetes associated autoantibodies.METHODS: The presence of ICA, IAA, GADA, IA2 antibodies and neutralizing antibodies (NtAb) to echovirus 16 were determined in sera from 38 infected children and adolescents and 80 control subjects, matched i

BACKGROUND: Recent outbreaks of poliomyelitis caused by vaccine-derived virus have raised concerns that vaccine-derived poliovirus may continue to circulate after eradication. In these outbreaks, the virus appears to have replicated for > or =2 years before detection. Early detection is critical for an effective response to these outbreaks. Although acute flaccid paralysis (AFP) surveillance will

INTRODUCTION: Poliomyelitis is currently a rare disease in developed countries, where only vaccinal strains seem to be in circulation, which replace wild poliovirus. Nevertheless, it is still a serious disease for children in underdeveloped countries of Asia and Africa.PATIENTS AND METHODS: We analysed nine strains of poliovirus type 2 isolated from the faecal matter of patients with vaccine assoc
