Skin necrosis: a rare complication of protein S deficiency.

Abstract: Hereditary protein S deficiency is an autosomal dominant disorder leading to recurrent venous thrombosis and, less commonly, to arterial thrombosis. Cases of skin necrosis have been documented in patients with protein C or S deficiency while being treated with warfarin. We describe herein a patient with protein S deficiency who developed significant skin necrosis without being exposed to warfarin. She had a protracted clinical course resulting in gangrene and transmetatarsal amputation. Recognition of this rare complication and an earlyhematology referral may prevent dismal outcomes in patients with protein S deficiency.

Maternal HIV status and infant feeding practices among Ugandan women

Abstract: practices, a questionnaire was administered to women attending the follow-up clinics for child vaccination. Among the mothers who were still breastfeeding at the time of interview (N=838), 61.4% of the HIV-infected women had planned to breastfeed for a maximum of 6 months, compared with 12.1% of the HIV-uninfected women (p<0.001). Among the women who were not breastfeeding at the time of interview (N=108), 82.5% of the HIV-infected women had stopped breastfeeding within 3 months, compared with 23.5% of the HIV-uninfected women (p<0.001). Only 2.1% of HIV-infected women seen up to 14 weeks postnatally practised mixed feeding, compared with 23.6% of HIV-uninfected women (p<0.001). After 6 months, however, 30% of the HIV-infected women and 55% of the HIV-uninfected mothers were using mixed feeding, with no significant differences. Programmes for the prevention of motherto-child transmission of HIV should re-enforce counselling activities to address the issue of early weaning by HIV-infected women, and to support safe breastfeeding up to 6 months.

Humans are Still the Best Lossy Image Compressors

Abstract: Lossy image compression has been studied extensively in the context of typical loss functions such as RMSE, MS-SSIM, etc. However, it is not well understood what loss function might be most appropriate for human perception. Furthermore, the availability of massive public image datasets appears to have hardly been exploited in image compression. In this work, we perform compression experiments in which one human describes images to another, using publicly available images and text instructions. These image reconstructions are rated by human scorers on the Amazon Mechanical Turk platform and compared to reconstructions obtained by existing image compressors. In our experiments, the humans outperform the state of the art compressor WebP in the MTurk survey on most images, which shows that there is significant room for improvement in image compression for human perception. The images, results and additional data is available at https://compression.stanford.edu/human-compression

Incidence and circumstances of pediatric fall-related injuries: Which fall variables matter?

Abstract: Background This study’s purpose was to determine if age, fall height, fall mechanism, landing surface, and landing position are associated with injury severity and hospital outcomes among pediatric fall patients. Methods A retrospective review was conducted of patients aged ≤18 years who sustained fall-related injuries admitted to an American College of Surgeons verified Level 1 trauma center from January 1, 2006 through December 31, 2015. Results Patient age, fall mechanism, landing position, and landing surface were associated with the need for surgery. Patient age, fall mechanism, and landing position were also associated with intensive care unit admissions. Fall mechanism was the only variable associated with injury severity. No variables were associated with the need for mechanical ventilation or mortality. Conclusions Patient age, fall mechanism, landing surface, and landing position need to be considered with regard to injury severity and patient outcomes among pediatric fall patients.
