Public Health Implications of Evictions: Modeling the Costs for Landlords, Tenants, and Society
In the United States, more than 13% of renters experience a formal or informal eviction in their lifetime. Forced moves contribute to a decline in job status, mental and physical health, material possessions, safety, social networks, housing aid, and neighborhood stability. Previous research has explored the risk factors, causes, and costs to those burdened by evictions. However, the costs of evictions incurred by all stakeholders involved in the process of evictions and homelessness remain largely unexplored. The homeownership rate in New Haven is less than 30%, and more than 52% of households are ‘cost-burdened,’ meaning more than 30% of income “is spent on housing costs associated with owning or renting a home.” Thus, this project set out to analyze the contributing burdens of costs within New Haven, Connecticut.https://elischolar.library.yale.edu/ysph_pbchrr/1016/thumbnail.jp
Secondary Analysis of RTOG 9508, a Phase 3 Randomized Trial of Whole-Brain Radiation Therapy Versus WBRT Plus Stereotactic Radiosurgery in Patients With 1-3 Brain Metastases; Poststratified by the Graded Prognostic Assessment (GPA)
PURPOSE: Radiation Therapy Oncology Group (RTOG) 9508 showed a survival advantage for patients with 1 but not 2 or 3 brain metastasis (BM) treated with whole-brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS) versus WBRT alone. An improved prognostic index, the graded prognostic assessment (GPA) has been developed. Our hypothesis was that if the data from RTOG 9508 were poststratified by the GPA, the conclusions may vary. METHODS AND MATERIALS: In this analysis, 252 of the 331 patients were evaluable by GPA. Of those, 211 had lung cancer. Breast cancer patients were excluded because the components of the breast GPA are not in the RTOG database. Multiple Cox regression was used to compare survival between treatment groups, adjusting for GPA. Treatment comparisons within subgroups were performed with the log-rank test. A free online tool (brainmetgpa.com) simplified GPA use. RESULTS: The fundamental conclusions of the primary analysis were confirmed in that there was no survival benefit overall for patients with 1 to 3 metastases; however, there was a benefit for the subset of patients with GPA 3.5 to 4.0 (median survival time [MST] for WBRT + SRS vs WBRT alone was 21.0 versus 10.3 months, P = .05) regardless of the number of metastases. Among patients with GPA 3.5 to 4.0 treated with WBRT and SRS, the MST for patients with 1 versus 2 to 3 metastases was 21 and 14.1 months, respectively. CONCLUSIONS: This secondary analysis of predominantly lung cancer patients, consistent with the original analysis, shows no survival advantage for the group overall when treated with WBRT and SRS; however, in patients with high GPA (3.5-4), there is a survival advantage regardless of whether they have 1, 2, or 3 BM. This benefit did not extend to patients with lower GPA. Prospective validation of this survival benefit for patients with multiple BM and high GPA when treated with WBRT and SRS is warranted
Homozygosity and severity of phenotypic presentation in a CADASIL family
8noMost of causative mutations of the cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) are missense point mutations either creating or deleting one cysteine residue, inherited in a heterozygous state. Only few homozygous patients are reported to date and some of them showed phenotypic peculiarities. We here describe a CADASIL family in which a member showed homozygous mutation and compare its clinical profile with five subjects throughout three generation of the pedigree, carrying the same mutation in heterozygosity. The index patient was a 44-year-old Italian man, born from consanguineous parents (first cousins). Symptoms started at 23 years and progressing with recurrent ischemic stroke episode. Diffuse leukoencephalopathy and a severe cognitive impairment were evident, GOMs were detected in skin specimens and a homozygous p.Cys183Ser mutation of the NOTCH3 gene was found. Among the other five heterozygous relatives for the same mutation, both parents developed stroke in advanced age and all the others were clinically asymptomatic. We discuss these findings in relationship to previous data from the literature in CADASIL and in other dominant neurological disorders.reservedmixedVinciguerra, Claudia; Rufa, Alessandra; Bianchi, Silvia; Antonio, Sperduto; Monica, Santis; Malandrini, Alessandro; Dotti, Maria; Federico, AntonioVinciguerra, Claudia; Rufa, Alessandra; Bianchi, Silvia; Antonio, Sperduto; Monica, Santis; Malandrini, Alessandro; Dotti, Maria; Federico, Antoni
Synthesis and physicochemical characterization of pyrrolidinium based surfactants
Three new pyrrolidinium based surfactants were synthesized and characterized as pure aggregate components and in mixtures with 1,2-dimyristoyl- sn-glycero-3-phosphocholine to understand how the molecular structure of the cationic amphiphile and its mole percentage might affect the physicochemical properties of the resulting aggregates. The thermotropic behavior of the mixed liposomes was investigated by differential scanning calorimetry on multilamellar vesicles, whereas their size and surface potential were investigated on large unilamellar vesicles by dynamic laser light scattering and fluorescence experiments, respectively. The presence of either methoxy or hydroxy groups in the positions 3 and 4 of the pyrrolidinium ring as well as the presence of a second alkyl chain on pyrrolidinium nitrogen, controls the aggregates features. © 2012 Elsevier Inc
