The data indicate that RLP particles are elevated in diabetic subjects. To achieve optimal reduction of risk for cardiovascular disease, treatment of elevated RLP values, along with the control of LDL cholesterol levels, should be considered.

Remnants of triglyceride-rich lipoproteins of both intestinal and liver origin are considered atherogenic, but they have been difficult to isolate and measure. An assay has been developed that allows the measurement of remnant-like particle cholesterol (RLP-C) and triglyceride (RLP-TG). RLP-C and RLP-TG concentrations were measured in >3000 fasting plasma samples obtained from participants in exam cycle 4 of the Framingham Offspring Study and stored at −80 °C. After exclusions, comparisons were made for 2821 samples (1385 women, 1436 men; mean age, 52 years). For women, the mean RLP-C and RLP-TG values were 0.176 ± 0.058 mmol/L (6.8 ± 2.3 mg/dL) and 0.204 ± 0.159 mmol/L (18.1 ± 14.1 mg/dL), respectively; for men, the mean values were 0.208 ± 0.096 mmol/L (8.0 ± 3.7 mg/dL) and 0.301 ± 0.261 mmol/L (26.7 ± 23.1 mg/dL), respectively. Women had significantly lower RLP-C and RLP-TG values (P <0.0001) than men; premenopausal women had significantly lower values than postmenopausal women (P <0.0001); and younger subjects (<50 years) had significantly lower values than older individuals (P <0.0001). The 75th percentile values for RLP-C and RLP-TG were 0.186 mmol/L (7.2 mg/dL) and 0.225 mmol/L (19.9 mg/dL), respectively, for women, and 0.225 mmol/L (8.7 mg/dL) and 0.346 mmol/L (30.6 mg/dL) for men. These data provide reference ranges for use in the evaluation of RLP-C and RLP-TG as potential indicators of risk for coronary heart disease.

Emergency general surgery patients have increased ICU needs in terms of length of stay, ventilator usage, and continuous renal replacement therapy usage compared with other services, perhaps due to the higher percentage of transfers and emergent surgery required. These patients represent a distinct population. Understanding their resource needs will allow for better deployment of hospital resources.
