Pneumonia

Pneumonia is a leading cause of death and hospitalization, costing health care systems billions of dollars and an estimated 600,000 adult deaths worldwide each year. Pneumococcal disease is caused by the bacterium Streptococcus pneumoniae and the term describes a group of illnesses, including invasive infections, such as bacteremia/sepsis and meningitis, as well as pneumonia and upper respiratory tract infections. Although all age groups may be affected, the highest rate of pneumococcal disease occurs in young children and older adults. In addition, persons suffering from a wide range of chronic conditions (eg, diabetes, cardiovascular disease) and immune deficiencies are at increased risk.

Pneumonia Symptoms & Risk Factors

Pneumonia is an acute respiratory infection where the alveolar sacs of the lungs become inflamed and fill with fluid or pus.

Severe COVID-19 infections in pregnant women do not increase risk of death

Pregnant women who develop severe COVID-19 infections that require hospitalization for pneumonia and other complications may not be more likely to die from these infections than non-pregnant women.

Hospitalized pregnant women less likely to die from COVID-19 than non-pregnant patients

Pregnant women who are hospitalized with COVID-19 and viral pneumonia are less likely than non-pregnant women to die from these infections, according to a new study by researchers with The University of Texas Health Science Center at Houston and the University of Maryland School of Medicine.

Severe COVID-19 linked to genetic clotting predisposition

Thus, the need to stratify the risk of severe or critical disease in patients presenting with SARS-CoV-2 infection remains a crying necessity. A new preprint research paper posted to the medRxiv server discusses the relationship between severe disease and pre-existing susceptibility to clots and other diseases of the cardiovascular system.

Researchers improve method to inhibit viruses that cause childhood respiratory infections

By engineering a short chunk of protein, or peptide, that can prevent the attachment of human parainfluenza viruses to cells, researchers have improved a method in rodent models intended to help keep children healthy.

Researchers identify first biomarker to predict severity of COVID-19

Severe cases of COVID-19 can now be detected at an early stage. Researchers at the University of Zurich have identified the first biomarker that can reliably predict which patients will develop severe symptoms.

$Hospitalized COVID-19 patients with impaired first-phase ejection fraction have higher death risk$

Hospitalized COVID-19 patients with impaired first-phase ejection fraction have higher death risk

Hospitalized COVID-19 patients with impaired first-phase ejection fraction were nearly 5 times more likely to die compared to patients with healthier measures of this early, often undetected sign of heart failure, according to new research published today in Hypertension, an American Heart Association journal.

Is COVID-19 a new disease?

In a review recently published in The Lancet Respiratory Medicine journal by Osuchowski et al. (May 6th, 2021) the currently known pathophysiology of COVID-19 is laid out to describe the mechanistic features that make COVID-19 distinct from many conditions previously thought to be similar.

Researchers identify anti-inflammatory prodrug Minnelide with potential against SARS-CoV-2

Using a transgenic mouse model of COVID-19, they have observed that treatment with Minnelide reduces viral load and inflammation in the lungs and improves survival. The study is currently available on the bioRxiv* preprint server.

COVID-19 may impact the heart health of young, healthy adults

New research published in Experimental Physiology highlight the possible long term health impacts of COVID-19 on young, relatively healthy adults who were not hospitalized and who only had minor symptoms due to the virus.

Study investigates 12-month respiratory outcomes in patients hospitalized for COVID-19

A new study has shown that most patients discharged from hospital after experiencing severe COVID-19 infection appear to return to full health, although up to a third do still have evidence of effects upon the lungs one year on.

Could stem cells improve the outcome of ARDS in severe COVID-19?

A recent study, published in Stem Cells Translational Medicine, explores the safety and efficacy of stem cells, which have been touted as the panacea for a wide range of illnesses, ranging from chronic degenerative conditions to cancer.

Pregnancy may increase the risk of COVID-19 severity

Against the background of the COVID-19 pandemic, the impact of SARS-CoV-2 infection in pregnancy has been a subject of much controversy. In order to help answer the question as to whether this infection causes significant harm in pregnancy, a new study, released as a medRxiv* preprint, reports on the disease outcomes of this infection in pregnant women.

COVID-19 in pregnancy does not significantly increase respiratory illness in newborns, says study

A new study published in the journal JAMA offers reassuring evidence that infants born to mothers with coronavirus disease 2019 (COVID-19), or even asymptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have little increase in respiratory symptoms over babies born to uninfected mothers.
