The build up of fluid in the lungs increases the pressure in the lungs leading to vasoconstriction. The coupled vasoconstriction and pulmonary hypertension causes the right side of the heart to fail which in turn, increases the venous hydrostatic pressure in the body. The summation of these effects ultimately leads to peripheral edema and ascites. All in all, the left side failure of the heart will lead to pulmonary edema whereas right side failure will lead to peripheral edema and ascites. The non-immune form of hydrops fetalis has many causes including:
Iron deficiency anemia
Paroxysmal supraventricular tachycardia resulting in heart failure
Deficiency of the enzyme beta-glucuronidase. This enzyme deficiency is the cause of the lysosomal storage disease called mucopolysaccharidosis type VII. Congenital disorders of glycosylation
Parvovirus B19 (fifth disease) infection of the pregnant woman (most common cause)
Cytomegalovirus in mother
Congenital pulmonary airway malformation (formerly called congenital cystic adenomatoid malformation)
Maternal syphilis and maternal diabetes mellitus
Alpha-thalassemia can also cause hydrops fetalis when all four of the genetic loci for α globin are deleted or affected by mutation. This is termed Hb Barts (consists of y-4 tetramers). Uncommonly, Niemann-Pick disease Type C (NPC) and Gaucher disease type 2 can present with hydrops fetalis. Turner syndrome
Tumors, the most common type of fetal tumor being teratoma, particularly a sacrococcygeal teratoma.
A 2020 study conducted by INRIX, private company that analyzes traffic patters, behaviors and congestion, showed that as traffic levels returned to normal during the three-month period August to October 2020, growth in collisions (57%), outpaced the growth in miles traveled (22%) resulting in a higher than normal collision rate during this period.In France, the Ministry of Interior reported that traffic incidents, crash-related injuries, and fatalities dropped in 2020 compared with 2019. Fatalities dropped 21.4%, injuries dropped 20.9%, and incidents overall dropped 20%. In the same report, the ministry reported that the number of vehicles on the road dropped by 75%, which would indicate that the rate (incidents per vehicle-mile) in fact increased. Other
Other possibly hazardous factors that may alter a drivers soundness on the road include:

Irritability
Following specifically distinct rules too bureaucratically, inflexibly or rigidly when unique circumstances might suggest otherwise
Sudden swerving into somebodys blind spot without first clearly making oneself visible through the wing mirror
Unfamiliarity with ones dashboard features, center console or other interior handling devices after a recent car purchase
Lack of visibility due to windshield design, dense fog or sun glare
People-watching. Traffic safety culture, a variety of aspects of safety culture could impact on the number of crashes. Prevention
A large body of knowledge has been amassed on how to prevent car crashes, and reduce the severity of those that do occur.
