Screening for cardiovascular disease risk factors at baseline and post intervention among adults with intellectual disabilities in an urbanised Asian society.

Background: Adults with intellectual disabilities (ID) face significant barriers to screening participation. We determined predictors for regular cardiovascular health screening at baseline among adults with ID in Singapore, and evaluated the effectiveness of a 3-month screening intervention.

Methods: The study population involved all adults with ID aged ≥40 years receiving services from the Movement for the Intellectually Disabled of Singapore (MINDS), the largest such provider in Singapore.

Effects of Russell's viper venom on blood coagulation, platelets and the fibrinolytic enzyme system.

The effects of Russell's viper venom (RVV) on blood coagulation, platelts and fibrinolysis were studied in vivo and in vitro in rabbits and dogs as experimental subjects. RVV was shown to be a strong coagulant, and at the time of manifestation of bleeding due to consumption coagulopathy, the most striking hemostatic abnormalities were fall of fibrinogen level, reduction in platelet count, delayed ADP aggregation of platelets, increased fibrinolytic activity and presence of fibrin degradation products. These findings showed that RVV interfered with blood coagulation, caused abnormalities of platelet function and also activated the fibrinolytic enzyme system.

Changes in the tissues of the immune system in dengue haemorrhagic fever.

A total of 100 post-mortems were done on patients clinically diagnosed as dengue haemorrhagic fever from Rangoon Children's Hospital. Histopathological changes in bone marrow, thymus, spleen, lymph nodes and other associated tissues of the immune system were analysed and correlated with the clinical picture and serology results. The major changes in cases with a positive serology result for secondary dengue infection consist of hypoplasia of the bone marrow, acute atrophy and wasting of the thymus, atrophy and depletion of cells in the periarterial lymphatic sheaths of the spleen and the paracortical areas of the lymph nodes.
