Get the flu vaccine, reduce your risk of death

Last year was a lousy year for the flu vaccine. Hospitalizations for flu hit a nine-year high, and the vaccine prevented flu in only 23% of all recipients, compared with 50% to 60% of recipients in prior years. Why does the flu vaccine work well in some winters and not others? The flu vaccine primes the immune system to attack two proteins on the surface of the influenza A virus, hemagglutinin (H) and neuraminidase (N). Different flu strains have different combinations of these proteins — for example, the strains targeted by recent flu vaccines are H3N2 and H1N1. Unfortunately, the influenza virus is microbiology’s answer to Miley Cyrus: it can change enough in just one year to become completely unrecognizable. The H and N proteins are genetic chameleons that undergo constant transformation. This process is called antigenic drift, and it regularly flummoxes vaccine makers, public health experts, and your immune system. Developing the new flu vaccines Most flu vaccine in the United States is made from chicken eggs, using production methods that date back to 1945. This cumbersome technique requires 6-8 months of lead time to produce enough vaccine for the upcoming flu season. Every February, the World Health Organization and the Food and Drug Administration (FDA) make their best guess as to which flu strains should be covered by next winter’s vaccine, based on a review of circulating flu viruses from over 100 countries. But a lot can change in 8 months, especi...

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

Conclusions: This review results revealed a low utilization of postnatal care service. Antenatal care service utilization has a positive effect on postnatal care service utilization. Policymakers and programmers better considered more antenatal care service use as one strategy of enhancing the utilization of postnatal care service. PMID: 33029402 [PubMed - in process]

Authors: Debelew GT Abstract Despite several efforts globally, the problem of perinatal mortality remained an unsolved agenda. As a result, it continued to be an essential part of the third sustainable development goals to end preventable child deaths by 2030. With a rate of 33 per 1000 births, Ethiopia has the highest level of perinatal mortality in the world. Thus, determining the magnitude and identifying the determinants are very crucial for evidence-based interventions. A community-based longitudinal study was conducted in Southwest Ethiopia among 3474 pregnant women to estimate the magnitude of perinatal mort...

This study was aimed at assessing the magnitude of induced abortion and associated factors among students in Hawassa University, southern region, Ethiopia, 2019. Methods: An institutional-based cross-sectional study was conducted among a total of 422 students selected on the bases of a probability simple random sampling method. A pretested structured questionnaire was used to collect data. Analysis was made with SPSS 20. Descriptive summary and inferential statistics (binary logistic regression) were used with a 95% CI and P value of less than 5% as a level of significance. Findings were presented in tables, figure, an...

CONCLUSIONS: This single practice study showed total patient contact was similar over both sample periods, but most contact in 2020 was virtual. Further longitudinal multi-practice studies to confirm these findings and describe future consultation patterns are needed to inform general practice service delivery post-COVID-19.
