Abstract
INTRODUCTION Our objective was to perform a feasibility study using real-world data from a learning health system (LHS) to describe current practice patterns of wound closure and explore differences in outcomes associated with the use of tissue adhesives and other methods of wound closure in the pediatric surgical population to inform a potentially large study. METHODS A multi-institutional cross-sectional study was performed of a random sample of patients <18 y-old who underwent laparoscopic appendectomy, open or laparoscopic inguinal hernia repair, umbilical hernia repair, or repair of traumatic laceration from January 1, 2019, to December 31, 2019. Sociodemographic and operative characteristics were obtained from 6 PEDSnet (a national pediatric LHS) children's hospitals and OneFlorida Clinical Research Consortium (a PCORnet collaboration across 14 academic health systems). Additional clinical data elements were collected via chart review. RESULTS Of the 692 patients included, 182 (26.3%) had appendectomies, 155 (22.4%) inguinal hernia repairs, 163 (23.6%) umbilical hernia repairs, and 192 (27.8%) traumatic lacerations. Of the 500 surgical incisions, sutures with tissue adhesives were the most frequently used (n = 211, 42.2%), followed by sutures with adhesive strips (n = 176, 35.2%), and sutures only (n = 72, 14.4%). Most traumatic lacerations were repaired with sutures only (n = 127, 64.5%). The overall wound-related complication rate was 3.0% and resumption of normal activities was recommended at a median of 14 d (interquartile ranges 14-14). CONCLUSIONS The LHS represents an efficient tool to identify cohorts of pediatric surgical patients to perform comparative effectiveness research using real-world data to support medical and surgical products/devices in children.

Abstract
Objectives: Long-standing racial disparities, particularly between White and Black women, in maternal and birth outcomes necessitate an examination of the factors influencing these disparities. This study aimed to understand the experiences of women of color as they relate to pregnancy and/or birth complications to inform policy and strategy to decrease racial and ethnic health disparities. Methods: Six focus groups were conducted with women (n = 31) who were identified as a woman of color, were 18 years or older, self-identified as having experienced pregnancy or birth complications after 2016, and who spoke English. A focus group guide co-created with the research team, community partners, and peer researchers from the local community was utilized to elicit discussions related to barriers, successes, and existing opportunities to provide equitable care and services to families throughout the perinatal period. An inductive and iterative approach to qualitative analyses of the focus group transcripts was used to identify key themes. Results: The seven themes identified include: lack of knowledge, mental health, communication with providers, support systems, representation, social determinants of health, and discrimination and stigma. Women shared a variety of experiences related to their health care from before pregnancy into their post-partum period, revealing many areas for improvement to extant systems. Conclusion: The inclusion of voices of the populations most deeply affected by health disparities is crucial to understanding how care and services provided can be improved. This analysis suggests the need for change at multiple levels of the health care and social services systems. These experiences provide valuable insight into some of the many struggles and barriers that women of color face during pregnancy and beyond.

Abstract
Background Food insecurity and other social determinants of health are increasingly being measured at routine health care visits. Understanding the needs and behaviors of individuals or families who screen positive for food insecurity may inform the types of resources they need. The goal of this research was to identify modifiable characteristics related to endorsement of two food insecurity screener questions to better understand the resources necessary to improve outcomes. Methods Analysis was conducted focusing on cross-sectional survey data collected in 2015–2016 from participants (N = 442) living in urban neighborhoods in Ohio with limited access to grocery stores. Food insecurity was assessed by the endorsement of at least one of two items. These were used to categorize participants into two groups: food insecure(N = 252) or food secure (N = 190). Using logistic regression, we estimated the association between several variables and the food insecure classification. Results Those that used their own car when shopping for food had lower odds of reporting food insecurity, as did those with affirmative attitudes related to the convenience of shopping for and ease of eating healthy foods. As shopping frequency increased, the odds of food insecurity increased. Food insecurity also increased with experience of a significant life event within the past 12 months. There was an 81% increase in the odds of reporting food insecurity among participants who received Supplemental Nutrition Assistance Program benefits compared to those not receiving Supplemental Nutrition Assistance Program benefits. Conclusions Along with referrals to SNAP, clinicians can further address screening-identified food insecurity through provision of transportation supports and linkages to other social services while collaborating on community initiatives to promote convenient and easy access to healthy foods. The needs and behaviors associated with screens indicating food insecurity also have implications for impacting other SDH, and thus, health outcomes.

Abstract
AIMS Outdoor play, physical activity, and social cohesion are crucial indicators of community health. PlayStreets, a street play initiative to engage local children and families in outdoor play, physical activity, and social interactions, were implemented in a low-income neighborhood in Columbus, Ohio throughout the summer of 2019. This article aims to describe the implementation of a hospital-sponsored PlayStreets model executed through support from a community health initiative and to assess neighborhood impact through parent and child surveys. METHODS Approximately 350 children attended the events and 69 surveys were collected. Descriptive statistics were used to analyze survey data. RESULTS The mean age of children was 7 years, and the majority of children who attended were male. If not for PlayStreets, 55% of caregivers reported that their children would be inside. Event satisfaction levels were high, and 54% of caregivers said that they had more contact with their neighbors because of the events. CONCLUSIONS Hospital buy-in and community support were crucial to the success of the event. We found that this model can successfully engage the local community while increasing opportunity for childhood outdoor play, physical activity, and neighborhood social interaction.

Abstract
Twenty-eight Borrelia burgdorferi isolates from the Charleston, S.C., area are described. This represents the first report and characterization of the Lyme disease spirochete from that state. The isolates were obtained from December 1994 through December 1995 from the tick Ixodes scapularis, collected from vegetation, and from the rodents Peromyscus gossypinus (cotton mouse), Neotoma floridana (eastern wood rat), and Sigmodon hispidus (cotton rat). All isolates were screened immunologically by indirect immunofluorescence with monoclonal antibodies to B. burgdorferi-specific outer surface protein A (OspA) (antibodies H5332 and H3TS) and B. burgdorferi-specific OspB (antibodies H6831 and H614), a Borrelia (genus)-specific antiflagellin antibody (H9724), Borrelia hermsii-specific antibodies (H9826 and H4825), and two polyclonal antibodies (one to Borrelia species and another to B. burgdorferi). Six of the isolates were analyzed by exposing Western blots to monoclonal antibodies H5332, H3TS, H6831, and H9724. All isolates were also analyzed by PCR with five pairs of primers known to amplify selected DNA target sequences specifically reported to be present in the reference strain, B. burgdorferi B-31. The protein profiles of six of the isolates (two from ticks, one from a cotton mouse, two from wood rats, and one from a cotton rat) also were compared by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. We conclude that the 28 Charleston isolates are B. burgdorferi sensu stricto based on their similarities to the B. burgdorferi B-31 reference strain.

Abstract
This study investigated the pharmacokinetics of recombinant human epidermal growth factor (EGF) in the eyes of live rabbits and enucleated human eyes. After intracameral injection of 1.2 muCi (1.1 micrograms) of 125I-EGF into rabbit eyes, tissues in the anterior segment were analyzed for uptake of 125I-EGF after 1, 2, 4, and 24 hr. The half-life of EGF during the initial 4 hr was 1.3 +/- 0.6 hr (+/- the confidence limit at P = 0.05) in the cornea, 0.7 +/- 0.4 hr in the iris, 1.9 +/- 0.9 hr in the lens, and 0.6 +/- 0.5 hr in the aqueous humor (n = 18 for each tissue). Between 4-24 hr, the percent retention of EGF in the tissues (relative to the initial amount in respective tissue) is in the order of lens greater than cornea greater than iris greater than aqueous humor. The kinetics of EGF uptake by excised human corneas was determined by incubating the endothelial surface with 1.2 muCi/ml (100 ng/ml) of 125I-EGF for 4 hr at 37 degrees C or 4 degrees C. After 4 hr, the total amount of EGF accumulated in the corneas was 2.3 +/- 0.2 ng (+/- standard deviation; n = 6) at 37 degrees C, and 1.4 +/- 0.1 ng at 4 degrees C.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The pre-pro alpha-factor leader region of the yeast MF alpha 1 gene was used to direct the secretion of the human glycoprotein, erythropoietin (EPO), into the culture medium. An examination of the role of expression level on secretion of biologically active EPO indicated that there are several rate-limiting steps. These include processing of the alpha-factor-EPO precursor protein by the KEX2-encoded endoproteinase and transport of the protein through the secretory pathway. The rate-limiting steps for transport were early in the secretory pathway, probably from the endoplasmic reticulum to the Golgi apparatus.

Abstract
We have chemically synthesized the gene encoding bovine basic fibroblast growth factor (bFGF) and cloned it into a plasmid vector. This gene was then used as a template for site-directed mutagenesis to produce the human bFGF gene and a gene coding for an analog in which serine residues were substituted for the cysteine residues at positions 70 and 88. All three constructs were cloned and expressed in Escherichia coli and the proteins purified. The recombinant human and bovine bFGFs exhibited the potent mitogenic activity toward both fibroblasts and endothelial cells, which characterizes natural bFGF. The serine-70,88 analog and natural sequence bovine and human forms were equally active in all assays. Sulfhydryl titration of the purified recombinant bovine bFGF in 4.8 M guanidine hydrochloride indicated the presence of approximately two free sulfhydryl groups. This was consistent with the sequence analysis of peptides derived from trypsin digestion, which suggests that cysteines 70 and 88 exist in free sulfhydryl form while cysteines 26 and 93 form a disulfide bond. Circular dichroism shows that the protein has little ordered structure but is folded into a rigid tertiary configuration. Carboxymethylation of the free sulfhydryl groups resulted in no change in the mitogenic activity or conformation. These results are consistent with previous suggestions that, for tissue-derived bFGF, at least 2 of the 4 cysteines in the molecule are not involved in a disulfide bond.

Abstract
We measured the concentration of immunoreactive (IR) hEGF in various body fluids by radioimmunoassay (RIA) and evaluated its size heterogeneity by size exclusion high performance liquid chromatography combined with RIA or with time-resolved immunofluorometric assay (TR-IFMA). Mean concentration was 80 ng/ml in urine, 65 ng/ml in milk, 50 ng/ml in seminal plasma, 25 ng/ml in armpit sweat, 1 ng/ml in breast sweat, 0.3 ng/ml in third-trimester amniotic fluid, 3 ng/ml in saliva, 1.5 ng/ml in tears and 0.3 ng/ml in gastric juice. All the fluids except armpit sweat and gastric juice contained two to five molecular sizes of IR-hEGF. As well as the 6200-dalton (6.2 kDa) hEGF we found at least four other different molecular sizes with approximate weights of greater than or equal to 300, 150, 70 and 20 kDa. The authentic 6.2 kDa form made up greater than 90% of the total IR-hEGF in all except the amniotic fluid where its proportion was 71%, and the seminal plasma where the proportion could not be determined.

Abstract
Fusions between the cloned yeast alpha-factor structural gene and chemically synthesized DNA segments encoding human protein analogs have been constructed. The gene fusions encode hybrid proteins that include the first 89 amino acids of the native alpha-factor precursor fused to either a small (beta-endorphin, 31 amino acids) or large (alpha-interferon, 166 amino acids) foreign protein. Proteolytic cleavage sites involved in alpha-factor maturation from the native precursor immediately precede the foreign peptide in the hybrid protein. The alpha-factor promoter was utilized to express the gene fusions in Saccharomyces cerevisiae and resulted in the efficient secretion of the foreign proteins into the culture medium. The processing of the hybrid proteins has been characterized by amino acid sequence analysis of the secreted proteins. The proteolytic cleavages involved in the maturation of alpha-factor peptides from the native precursor also occur accurately in the hybrid protein. In addition, cleavages occurred on the carboxyl side of two lysines within the beta-endorphin peptide. Internal cleavages in the interferon protein were also detected. However, in this case, the cleavages occurred at a very low frequency such that greater than 95% of the secreted interferon remained intact.

Abstract
Mice treated with lethal doses of adriamycin (A1) (IP) are rescued with a single IP dose of 3,5,5-trimethyl-2-morpholinon-3-yl radical dimer (TM3). The in vivo rescue is assumed to be analogous to the in vitro reaction of TM3 with A1 that produces the non-toxic 7-deoxy-adriamycinone (7dAone). TM3 prevents death if given within 60 min following A1 administration. Control A1-treated mice died by 8 days (median survival time) whereas TM3 rescued A1-treated mice had a median survival time of greater than 60 days.
