Once & For All: Placing a Highly Qualified Teacher in Every Philadelphia Classroom

Quality teaching matters - particularly for low-income, inner-city students who perform below grade level. But these students are often taught by the least-qualified and least-experienced teachers. Philadelphia schools will not be able to improve student performance dramatically without more teachers who have the skills, experience, and rich content knowledge needed to help every student achieve high standards.Once & For All: Placing a Highly Qualified Teacher in Every Philadelphia Classroom examines the current status of teacher quality in the city and what the School District of Philadelphia is now doing to ensure that all classrooms have highly trained, motivated, and knowledgeable teachers ready to boost the achievement of the district's 188,000 students.For the first time, thanks to information provided by the School District of Philadelphia, researchers have been able to identify what we know about the qualifications, experience, and school assignment patterns of Philadelphia's 11,700-member teaching force. The study was conducted by a group of scholars who have launched Learning from Philadelphia's School Reform, a three-year research project designed to measure and help the public understand the impact of the 2001 state takeover of the Philadelphia schools, the school management partnerships undertaken with external for-profit and non-profit organizations, and the reforms initiated by the state and city-appointed School Reform Commission (SRC) members and School District of Philadelphia CEO Paul Vallas.Led by Research for Action (RFA), a Philadelphia non-profit, the research team includes investigators from the University of Pennsylvania's Graduate School of Education and the Wharton School, the Philadelphia Education Fund, Swarthmore College, Rutgers University, the Consortium on Chicago School Research, and other organization

Enacted stigma, mental health, and protective factors among transgender youth in Canada

Purpose: We aimed to assess the Minority Stress Model which proposes that the stress of experiencing stigma leads to adverse mental health outcomes, but social supports (e.g., school and family connectedness) will reduce this negative effect. Methods: We measured stigma-related experiences, social supports, and mental health (self-injury, suicide, depression, and anxiety) among a sample of 923 Canadian transgender 14- to 25-year-old adolescents and young adults using a bilingual online survey. Logistic regression models were conducted to analyze the relationship between these risk and protective factors and dichotomous mental health outcomes among two separate age groups, 14- to 18-year-old and 19- to 25-year-old participants. Results: Experiences of discrimination, harassment, and violence (enacted stigma) were positively related to mental health problems and social support was negatively associated with mental health problems in all models among both age groups. Among 14–18 year olds, we examined school connectedness, family connectedness, and perception of friends caring separately, and family connectedness was always the strongest protective predictor in multivariate models. In all the mental health outcomes we examined, transgender youth reporting low levels of enacted stigma experiences and high levels of protective factors tended to report favorable mental health outcomes. Conversely, the majority of participants reporting high levels of enacted stigma and low levels of protective factors reported adverse mental health outcomes. Conclusion: While these findings are limited by nonprobability sampling procedures and potential additional unmeasured risk and protective factors, the results provide positive evidence for the Minority Stress Model in this population and affirm the need for policies and programs to support schools and families to support transgender youth

Radiation therapy generates platelet-activating factor agonists

Pro-oxidative stressors can suppress host immunity due to their ability to generate oxidized lipid agonists of the platelet-activating factor-receptor (PAF-R). As radiation therapy also induces reactive oxygen species, the present studies were designed to define whether ionizing radiation could generate PAF-R agonists and if these lipids could subvert host immunity. We demonstrate that radiation exposure of multiple tumor cell lines in-vitro, tumors in-vivo, and human subjects undergoing radiation therapy for skin tumors all generate PAF-R agonists. Structural characterization of radiation-induced PAF-R agonistic activity revealed PAF and multiple oxidized glycerophosphocholines that are produced non-enzymatically. In a murine melanoma tumor model, irradiation of one tumor augmented the growth of the other (non-treated) tumor in a PAF-R-dependent process blocked by a cyclooxygenase-2 inhibitor. These results indicate a novel pathway by which PAF-R agonists produced as a byproduct of radiation therapy could result in tumor treatment failure, and offer important insights into potential therapeutic strategies that could improve the overall antitumor effectiveness of radiation therapy regimens

Topical Photodynamic Therapy Induces Immunosuppression: Potential Role of Lipid Mediator Platelet-Activating Factor

opical photodynamic therapy (PDT), or blue light therapy, isa procedure using a photosensitizing agent, or precursoragent 5-aminolevulinic acid (5-ALA), and is commonly usedto treat precancerous actinic keratosis. The 5-ALA is takenup by skin lesions through targeting cells with high turnoverthat are metabolically active (malignant proliferation) andconverted to the photoactive drug protoporphyrin IX.Following exposure to blue light, significant cell destructionoccurs which has been linked to the generation of reactiveoxygen species (1). Though PDT is effective, several studieshave suggested that this procedure results inimmunosuppression, which might limit the effectiveness ofthis therapy. Our group has demonstrated previously thatexperimental PDT of keratinocyte cell lines and murine skingenerates the lipid mediator Platelet-activating Factor (PAF).Moreover, we have found that PDT of wild-type mice resultsin immunosuppression, with PAF receptor knockout miceprotected from PDT-induced immunosuppression

Single Ablative Fractional Resurfacing Laser Treatment For Forearm Actinic Keratoses: 6-Month Follow-Up Data From An Intrapatient Comparison Between Treated and Untreated Sites

Background and objectives: Actinic keratoses (AK) are common pre-cancerous lesions, which are associated with ultraviolet light exposure and aging. Wounding therapies such as fractionated laser resurfacing (FLR) have been previously demonstrated to effectively treat facial AK. However, the effectiveness of FLR on other sites commonly afflicted with AK has not been studied in detail. Previously, our group has reported that treatment of aged skin with wounding therapies including dermabrasion and ablative fractionated resurfacing results in the removal of senescent fibroblasts and normalizing the pro-carcinogenic acute ultraviolet B radiation responses associated with aged skin. The current studies were designed to test the effectiveness of FLR of the forearm skin of subjects aged 60 and older to remove AKs. Study design/materials and methods: Between February 2018 and March 2019, 30 subjects were enrolled in a study, in which they underwent a single FLR treatment of one extremity including the dorsal forearm, wrist, and dorsal hand. The number of AKs was recorded on both extremities at baseline, 3 and 6 months in a blinded fashion. Side effects of the FLR were documented. Results: A single FLR treatment resulted in a 62% reduction in the absolute number of AK in the treated arm at 6 months post-treatment. The laser treatment was well-tolerated without major complications. Conclusions: These studies demonstrate that FLR using settings, which have demonstrated to remove senescent fibroblasts and normalize the pro-carcinogenic UVB-response of aged skin is a potentially effective and safe field therapy treatment that should be studied for long-term efficacy for use in treating upper extremity AKs
