Visceral brown fat necrosis in postperinatal mortality.

Visceral brown fat necrosis in postperinatal mortality.

Fat necrosis was present in 22 of 400 cases of consecutive postperinatal mortalities investigated to assess the presence and pattern of deep fat necrosis. In just over 50% of the cases of fat necrosis the cause of death was categorised as sudden infant death syndrome, which also showed more severe degrees of necrosis. The mechanism of necrosis may be vascular hypoperfusion, possibly related to ...

Whooping cough and unrecognised postperinatal mortality.

Trends in postperinatal infant mortality from respiratory causes and the sudden infant death syndrome in England and Wales for 1968 to 1984 were examined. These were compared by time series analysis with changes in the incidence of specific infective diseases and organisms for the same period. Discontinuity was found in association with the occurrence of whooping cough between 1977 and 1982. As...

Why did postperinatal mortality rates fall in the 1970s?

Postperinatal mortality rates have shown two phases of decline since 1947 which are traditionally ascribed to social and medical improvements. These factors cannot, however, explain the arrest of decline during the 1960s. There appears to be a biological effect on child mortality rates, manifesting as a generation effect. This is due partly to continuing changes in the structure of the child po...

Associations Among Visceral Fat, All-Cause Mortality, and Obesity-Related Mortality in Japanese Americans

OBJECTIVE The study objective was to examine the associations among visceral fat (VF), all-cause mortality, and obesity-related mortality. RESEARCH DESIGN AND METHODS A total of 733 Japanese Americans were followed for 16.9 years. Hazard ratios (HRs) per interquartile range increase in VF were calculated using time-dependent Cox proportional hazard models censored at age 82 years, with age as...
