An estimated 800 million people's food and income are threatened by rapidly spreading cassava diseases. But in good news for cassava breeders and farmers, breakthrough research has established the pathogens and the first diagnostic tests for two diseases: Cassava Frogskin Disease and Cassava Witches’ Broom Disease. This achievement can revolutionize cassava disease management across Latin America and the Caribbean as well as Southeast Asia, where farmers and researchers have been working side-by-side to fight the spread of these diseases for decades.
Nipah virus (NiV) is a zoonotic paramyxovirus that has recently emerged as a crucial public health issue. It can elicit severe encephalitis and respiratory diseases in animals and humans, leading to fatal outcomes, exhibiting a wide range of host species tropism, and directly transmitting from animals to humans or through an intermediate host. Human-to-human transmission associated with recurrent NiV outbreaks is a potential global health threat. Currently, the lack of effective therapeutics or licensed vaccines for NiV necessitates the primary utilization of supportive care. In this review, we summarize current knowledge of the various aspects of the NiV, including therapeutics, vaccines, and its biological characteristics, epidemiology, pathogenesis, and clinical features. The objective is to provide valuable information from scientific and clinical research and facilitate the formulation of strategies for preventing and controlling the NiV.
In a study of more than 5,000 mothers and their children, exposure to air pollution during the three months before pregnancy predicted higher child body mass index (BMI) and related obesity risk factors up to two years of age. In one of the largest studies to date of preconception environmental exposures, researchers from the Keck School of Medicine of USC, Duke University and Fudan University in Shanghai, China studied 5,834 mother-child pairs recruited from maternity clinics in Shanghai. They found that greater exposure to PM2.5, PM10 and NO2 before pregnancy was linked to increases in BMI or BMIZ, a standardized score that shows how a child’s BMI compares to others of the same age and sex. The findings imply that the three months before conception are important, and that people who plan to bear children should consider taking measures to lower their air pollution exposure to reduce their children’s risk for obesity.
