The incidence of venous thromboembolism was 3/546 (0.6%) in the obstetric inpatients. Our study found a high prevalence of venous thromboembolism risk among obstetric inpatients at the Korle-Bu Teaching Hospital. However, thromboprophylaxis was low. Further research is needed to audit recent practice of thromboprophylaxis and perinatal outcome.

Volatile flavor compounds examined by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O), combined with aroma extract dilution method (AEDA) and odor activity value (OAV) for identification of important odorants. In addition, the correlation between sensory attributes and volatile compounds of salmon irradiated at different doses was analyzed by partial least squares regression (PLSR). The results showed that after SPME and SAFE extraction, a total of 49 and 70 volatile flavor compounds were detected in salmon before and after electron beam irradiation. AEDA and OAV were further identified, among which 10 odorants were considered as important volatile flavor compounds and played an important role in the formation of aroma contours such as meaty, fatty, and grassy in salmon. In addition, methanethiol, 3-methyl butyraldehyde, 3-methyl propyl aldehyde, dimethyl disulfide, dimethyl trisulfide, and 2-pentyl furan were id
