The Long-Lasting Influenza: The Impact of Fetal Stress During the 1918 Influenza Pandemic on Socioeconomic Attainment and Health in Sweden, 1968 –2012
This study combines several sources of contemporary statistics with full-population individual-level data for Sweden during 1968 –2012 to examine the influence of fetal exposure to the Spanish flu on health, adulthood income, and occupational attainment. For both men and women, fetal exposure resulted in higher morbidity in ages 54–87, as measured by hospitalization. For males, exposure during the second trimester also af fected mortality in cancer and heart disease. Overall, the effects on all-cause mortality were modest, with about three months shorter remaining life expectancy for the cohorts exposed during ...

Protective Antibodies Against Influenza Proteins
The influenza A virus infection continues to be a threat to the human population. The seasonal variation of the virus and the likelihood of periodical pandemics caused by completely new virus strains make it difficult to produce vaccines that efficiently protect against this infection. Antibodies are very important in preventing the infection and in blocking virus propagation once the infection has taken place. However, the precise protection mechanism provided by these antibodies still needs to be established. Furthermore, most research has focused on antibodies directed to the globular head domain of hemagglutinin. Howev...

Conclusions: The clinical features and outcomes of pandemic (H1N1) 2009 influenza and current circulating seasonal influenza A strains were comparable in hospitalised patients. However, since both seasonal and pandemic influenza can lead to significant morbidity and mortality, the impact of pre-existing seasonal influenza should not be underestimated during the pandemic period.

Plague before the Pandemics: The Greek Medical Evidence for Bubonic Plague before the Sixth Century.
This article evaluates the textual evidence for bubonic plague in classical antiquity from medical sources and discusses methodologies for "retrospective diagnosis" in light of new developments in microbiology. A close study of Greek medical texts suggests that bubonic plague was unfamiliar to medical writers until sometime before the second century AD, when sources cited by Rufus of Ephesus report a disease that resembles bubonic plague. Rufus of Ephesus describes this disease around AD 100, and Aretaeus (fl. ca. AD 50 or 150) appears to describe the same disease as well. Intriguingly, the disease then disappear...

Narcolepsy and Pandemic Influenza Vaccination: What We Need to Know to be Ready for the Next Pandemic
After the initial identification of the H1N1 pandemic influenza strain in Mexico in April 2009 and its subsequent global spread, several monovalent influenza vaccines were developed as part of the pandemic response. Three of these vaccines, Pandemrix, Arepanrix and Focetria were adjuvanted. One of these, the AS03-adjuvanted Pandemrix vaccine, was primarily used in Europe. Following widespread Pandemrix vaccine administration in Scandinavia, an increased risk of narcolepsy was noted in observational studies. Subsequently, this increased risk was also reported in other European countries as well. In contrast, studies from Ca...

IJERPH, Vol. 16, Pages 2487: Race and 1918 Influenza Pandemic in the United States: A Review of the Literature
Mamelund During epidemics, the poorest part of the population usually suffers the most. Alfred Crosby noted that the norm changed during the 1918 influenza pandemic in the US: The black population (which were expected to have higher influenza morbidity and mortality) had lower morbidity and mortality than the white population during the autumn of 1918. Crosby&rsquo;s explanation for this was that black people were more exposed to a mild spring/summer wave of influenza earlier that same year. In this paper, we review the literature from the pandemic of 1918 to better understand the crossover in the role of race...

ConclusionsMechanisms responsible for nonhemolysis of the epidemic O1 El Tor strains are complex and not only confined to gene mutation but also deficiencies of transcription and extracellular transport of HlyA.

Intensive Care Unit Preparedness During Pandemics and Other Biological Threats
In the twenty-first century, severe acute respiratory syndrome (SARS), 2009 A(H1N1) influenza, and Ebola have all placed strains on critical care systems. In addition to the increased patient needs common to many disasters, epidemics may further degrade ICU capability when staff members fall ill, including in the course of direct patient care. In a large-scale pandemic, shortages of equipment and medications can further limit an ICU ’s ability to provide the normal standard of care. Hospital preparedness for epidemics must include strategies to maintain staff safety, secure adequate supplies, and have plans for triag...

The Obesity-associated Risk in Open and Endovascular Repair of Abdominal Aortic Aneurysm.
Abstract The rising pandemic of obesity in modern society should direct attention to a more comprehensive approach to abdominal aortic aneurysm (AAA) treatment in the affected population. Although overweight patients are considered prone to increased surgical risk, studies on the subject did not confirm or specify the risks well enough. Associated comorbidities inevitably lead to a selection bias leaning towards endovascular abdominal aortic repair (EVAR), as a less invasive treatment option, which makes it hard to single out obesity as an independent risk factor. Increased technical difficulty often results in pr...

The relevant aspects of the OCV studies, such as boosting the effect of vaccine, single-dose versus double-dose trials and thermal stability of the vaccine during delivery have generated strong evidence for recommendation of vaccine use in these settings. Studies have shown that a single dose is effective for children of five years of age and older age groups. The locally manufactured vac...

Abstract Avian influenza virus (AIV) is an extraordinarily diverse pathogen that causes significant morbidity in domesticated poultry populations and threatens human life with looming pandemic potential.

Acta Virol. 2019;63(2):203-210 Authors: Zhang YY, An J, Wang K, Han B, Liu YF, Jia HL, Li YS, Lei L, Jia N, Lv J Abstract The nasal-associated lymphoid tissues (NALTs), embedded in the submucosa of murine upper respiratory tract, represents an important site of induction for local mucosal immune responses to airborne pathogens and intranasal vaccines. Here, we systematically investigated the mucosal humoral and cellular immune responses of NALTs in mice infected with A/Beijing/501/2...

Phylogenetic analysis of HA and NA genes of influenza H1N1 viruses from 1918 to 2017.
Abstract The 1918 "Spanish" pandemic is the earliest known influenza H1N1 virus. Since then H1N1 viruses circulated between humans and animals continuously. With the increased amount of samples of H1N1 viruses and technology development, researchers have been studying how the viruses evolved. Here, we analyzed HA and NA genes of H1N1 viruses from three aspects: host distribution, geographical distribution and phylogenetic analysis. The data showed hosts were predominantly human, swine and poultry, and other hosts were mainly cat, ferret, wild bear, canine, cheetah and seal. In terms of geographical distr...

Phylogeographic Analyses Reveal the Early Expansion and Frequent Bidirectional Cross-Border Transmissions of Non-pandemic HIV-1 Subtype B Strains in Hispaniola
In this study, we reconstruct the dynamics of dissemination of early divergent non-pandemic subtype B lineages (designated BCAR) in Hispaniola. To this end, we analyzed 127 HIV-1 subtype B pol sequences collected in Haiti between 2009 and 2014, combined with BCAR pol sequences from Haiti (n = 12) and the Dominican Republic (n = 123) previously described. Phylogenetic analyses supported that BCAR strains account for most (>70%) of HIV-1 subtype B infections in Haiti. The BCAR strains from Haiti and the Dominican Republic were highly intermixed among each other, although the null hypothesis of completely random mixing was...
