Effects of sodium restriction on blood pressure, renin, aldosterone, catecholamines, cholesterols, and triglyceride: a meta-analysis

Article Abstract:

Dietary sodium restriction may be beneficial in people with hypertension but it does not appear to benefit those with normal blood pressure. Researchers evaluated 114 clinical trials evaluating the effect of sodium restriction on blood pressure. Fifty-eight trials of hypertensive patients found that sodium restriction lowered systolic and diastolic blood pressure by a small amount. However, blood pressure in 56 trials of people with normal blood pressure was not affected by sodium restriction. Sodium restriction is probably not necessary for most people.

Risk Factors for Parvovirus B19 Infection in Pregnancy

Article Abstract:

Exposure to children appears to be the greatest risk factor for parvovirus B19 infection during pregnancy. This infection can lead to fetal death. Researchers analyzed risk factors for parvovirus B19 infection in 30,946 pregnant women. Based on blood tests, 65% had evidence of past infection. Risk factors included having brothers and sisters the same age, having children and especially more than one child. Exposure to a 6- or 7-year old child was the biggest risk factor. Nursery school teachers had a high risk of infection.

Acute Respiratory Tract Infections and Mannose-Binding Lectin Insufficiency During Early Childhood

Article Abstract:

Children with a deficiency of mannose-binding lectin have twice the risk of developing a respiratory tract infection, according to a study of 251 children. Mannose-binding lectin is a protein that is believed to participate in the immune response to infectious organisms.
