The LD model achieved a 71% total accuracy and 81% sensitivity to higher risk samples. Prognostic information extracted from the stromal morphology has potential to complement OncotypeDX as an easy-to-implement prescreening methodology.
Infections are the leading cause of therapy-related mortality in pediatric patients with acute myeloid leukemia (AML). Although effectiveness of levofloxacin antibacterial prophylaxis in oncology patients is recognized, its cost-effectiveness is unknown. This study evaluated epidemiologic data regarding levofloxacin use and the cost-effectiveness of this strategy as the cost per bacteremia episode, intensive care unit (ICU) admission, and death avoided in children with AML.

A retrospective cohort study using the Pediatric Health Information System (PHIS) database compared demographic and clinical characteristics and receipt of levofloxacin prophylaxis in children with AML admitted for chemotherapy from January 1, 2014, through December 31, 2018. We then developed a decision analysis model in this population that compared costs associated with bacteremia, ICU admission, or death secondary to bacteremia to levofloxacin prophylaxis cost from a healthcare perspective. Time horizon is one chemotherapy cycle. Pection secondary to myelosuppression.
To report a single-center experience with thrombolytic therapy using recombinant tissue plasminogen activator (rt-PA) in preterm neonates with severe thrombotic events, in terms of thrombus resolution and bleeding complications.

This retrospective study included 21 preterm neonates with severe venous thrombotic events admitted to the neonatal intensive care unit, identified in our pharmacy database from January 2001 to December 2016, and treated with rt-PA until complete or partial clot lysis, no-response or bleeding complications. Our primary outcome was thrombus resolution.

Twenty-one preterm neonates were treated with rt-PA for an average of 2.9cycles. Seventeen patients (80.9%) had superior vena cava thrombosis and superior vena cava syndrome. All patients had a central venous catheter, parenteral nutrition, mechanical ventilation, and sepsis. Fifteen patients (71.4%) were extremely preterm, 11 (52.4%) were extremely low birth weight, and seven (33.3%) were very low birth weight. The patency rate wahom the benefits of the thrombolytic treatment outweigh the risks of bleeding.Influenza A viruses (IAVs) have both zoonotic and anthroponotic potential and are of public and veterinary importance. Swine are intermediate hosts and 'mixing vessels' for generating reassortants, progenies of which may harbour pandemic propensity. Swine handlers are at the highest risk of becoming infected with IAVs from swine but there is little information on the ecology of IAVs at the human-animal interface in Africa. We analysed and characterized nasal and throat swabs from swine and farmers respectively, for IAVs using RT-qPCR, from swine farms in the Ashanti region, Ghana. Sera were also analysed for IAVs antibodies and serotyped using ELISA and HI assays. IAV was detected in 1.4% (n = 17/1,200) and 2.0% (n = 2/99) of swine and farmers samples, respectively. Selleck Odanacatib Viral subtypes H3N2 and H1N1pdm09 were found in human samples. All virus-positive swine samples were subtyped as H1N1pdm09 phylogenetically clustering closely with H1N1pdm09 that circulated among humans during the study period. Phenotypic markers that confer sensitivity to Oseltamivir were found. Serological prevalence of IAVs in swine and farmers by ELISA was 3.2% (n = 38/1,200) and 18.2% (n = 18/99), respectively. Human H1N1pdm09 and H3N2 antibodies were found in both swine and farmers sera. Indigenous swine influenza A viruses and/or antibodies were not detected in swine or farmers samples. Majority (98%, n = 147/150) of farmers reported of not wearing surgical mask and few (4%, n = 6) reported to wear gloves when working. Most (n = 74, 87.7%) farmers reported of working on the farm when experiencing influenza-like illness. Poor husbandry and biosafety practices of farmers could facilitate virus transmission across the human-swine interface. Farmers should be educated on the importance of good farm practices to mitigate influenza transmission at the human-animal interface.
The development of the endoscopic technique has resulted in an increasing number of patients undergoing percutaneous endoscopic gastrostomy (PEG) insertion; however, the protocols for increasing the volume of feeding formula after PEG insertion have not been established. Therefore, we compared the clinical outcomes of patients receiving low- and high-volume increase in enteral feeding formula.

A total of 215 patients who underwent PEG insertion between January 2016 and March 2019 were included. They were divided into 2 groups according to the increase in volume of feeding formula the low-volume group (n = 135) received ≤150 mL/d, and the high-volume group (n = 80) received ≥300 mL/d. Patient characteristics, procedure, and feeding-related clinical outcomes were retrospectively reviewed using medical records.

The adverse events of the feeding protocol did not significantly differ between the 2 groups. The number of days needed to attain the calorie targets was significantly lower in the high-volume group than in the low-volume group (5.4 ± 3.0 vs 2.4 ± 1.5; P < .001). The duration of supplemental parenteral nutrition and the length of hospitalization were also significantly lower in the high-volume group (3.9 ± 3.3 vs 1.2 ± 2.2; P < .001 and 5.8 ± 2.7 vs 4.6 ± 2.6; P = .007, respectively).

To rapidly attain the calorie targets in appropriately selected patients with PEG insertion, a high-volume increase in daily feeding can safely be recommended given the favorable outcomes.

Children with sickle cell disease (SCD) are at increased risk for bacterial infections including osteomyelitis (OM). Fever and bone pain, key presenting symptoms of OM, are common in SCD, thus complicating diagnosis. We reviewed presentation, imaging features, and microbiologic etiologies of children with SCD treated for OM.

The comprehensive SCD clinical database of children and adolescents with SCD followed at a single, large tertiary pediatric center were searched to identify all diagnostic coding for potential cases of osteomyelitis in children ages 6months to 21years from 2010 to 2019. Medical charts were reviewed to determine OM diagnostic probability based on radiographic and microbiologic findings and the duration of prescribed antibiotic treatment for OM.

Review of 3553 patients (18039 person-years) identified 20 episodes of probable OM in 19 children. Magnetic resonance imaging (MRI) findings to support OM were definitive in 4/19 (21%), probable in 10/19 (53%), suspected in 5/19 (26%), based on blinded radiologist review.
