  • Feasibility and Perceptions of Cell Phone-Based, Health-Related Communication With Adolescents in an Economically Depressed Area CLINICAL PEDIATRICS Sawni, A., Cederna-Meko, C., LaChance, J. L., Buttigieg, A., Quoc Le, Q., Nunuk, I., Ang, J., Burrell, K. M. 2017; 56 (2): 140-145


    We examined the feasibility and perception of cell-based (texting, voicemail [VM], and email/social media), health-related communication with adolescents in Genesee County, MI, where 22% reside below the poverty level. Results of an anonymous survey found that 86% of respondents owned a cell phone, 87% had data, 96% texted, 90.5% emailed/used social media, and 68% had VM. Most adolescents were interested in cell-based communication via texting (52%), VM (37%), and email/social media (31%). Interest in types of health communication included appointment reminders (99% texting; 94% VM; 95% email/social media), shot reminders (84.5% texting; 74.5% VM; 81% email/social media), call for test results (71.5% texting; 75% VM; 65% email/social media), medication reminders (63% texting; 54% VM; 58% e-mail/social media), and health tips (36% texting; 18.5% VM; 73% email/social media). Cell-based health-related communication with adolescents is feasible even within low socioeconomic status populations, primarily via texting. Health providers should embrace cell-based patient communication.

  • Heme Oxygenase Activity and Heme Binding in a Neonatal Mouse Model NEONATOLOGY Kourula, S., Ang, J., Zhao, H., Kalish, F., Vandenabeele, P., Sylvester, K. G., Wong, R. J., Stevenson, D. K. 2017; 112 (4): 376–83


    Severe hemolytic disease of the newborn leads to the release of pro-oxidative free heme (FH). Heme oxygenase (HO) is primarily responsible for detoxifying FH.To investigate the protective effects of HO in a model of heme overload.For in vitro studies, NIH3T3 HO-1-luc cells were incubated with 10, 30, or 60 µM FH or methemalbumin (MHA). HO-1 promoter activity was assessed 3, 6, and 24 h after treatment. Cell survival was indexed by viability assays. For in vivo studies, 1- and 5-week-old wild-type (Wt) or HO-1-heterozygous (Het, HO-1+/-) mice were given 60 µmol FH or MHA/kg intraperitoneally. After 24 h, plasma aspartate aminotransferease (AST)/alanine transaminase (ALT) and hemopexin, liver HO activity, and lipid peroxidation (LP) were determined.In HO-1-luc cells, HO-1 promoter activity peaked 6 h after incubation with 30 µM FH (1.6-fold) or 60 µM MHA (2.1-fold) over baseline. Twenty-four hours after exposure to 60 µM FH, a decrease in viability of 80% was found, compared with no decrease after exposure to 60 µM MHA. In 1-week-old Wt and HO-1 Het pups given 60 µmol FH/kg, HO activity significantly increased 3.5- and 3.1-fold, respectively. No changes in LP or AST/ALT levels were observed. In adult Wt and HO-1 Het mice, HO activity increased (3.0- and 2.6-fold, respectively). LP and AST levels significantly increased 28.4- and 2.7-fold, respectively, in adult HO-1 Het mice. Hemopexin levels at baseline were higher in adults compared with newborns for both Wt and Het mice. In addition, FH induced hemopexin levels in both adults and newborns, but to a lesser degree in newborns.FH is highly toxic in vitro, but its toxicity is abolished when bound to albumin. Newborns appear to be protected from the pro-oxidative effects of FH, which may be mediated by heme binding and a higher absolute HO activity at baseline and after FH-mediated induction.
