Room-Temperature On-Spin-Switching and Jamming a new Porphyrin-Based Dual purpose Program.
2Gy to 1.2Gy. For the contralateral PG, this value decreased from 2.9Gy to 0.8Gy. CONCLUSION During the H&N inverse planning, the optimized model guides to the lowest PG achievable mean dose, allowing a significant PG mean dose reduction of -6.1Gy. Integrating this method at the treatment-planning step significantly reduced the inter-patient and inter-operator variabilities. OBJECTIVES In this study, we examined the quantitative significance of humoral immunity by flow-cytometric crossmatch using molecules of equivalent soluble fluorochromosome (FCXM-MESF) in recipients of kidney transplantation. We stratified the recipients into four sensitization classes, from non-sensitized to strongly sensitized by the results of the FCXM-MESF assay, and compared the pathological results after transplantation by the sensitization status. MATERIALS AND METHODS We stratified 140 recipients into four groups according to their sensitization status, as follows; none/NDSA, defined by FCXM-MESF values of below the cut-off value (n = 79), mildly sensitized, defined by FCXM-MESF values of less than 3000 (N = 45); moderately sensitized, defined by FCXM-MESF values of between 3000 and 8000 (N = 12); strongly sensitized, defined by FCXM-MESF values exceeding 8000 (N = 4). RESULTS We employed tailor-made immunosuppressive regimens according to the FCXM-MESF values for the 140 recipients between 2009 and 2011. In regard to the pathological results, 4% (2/51), 3% (1/35), 20% (2/10) and 75% (3/4) of the none/Non Donor Specific Antibody (NDSA), mildly sensitized, moderately sensitized and strongly sensitized patients showed antibody mediated rejection (AMR). Thus, FCXM may be more useful for the detection of anti-non-HLA as well as for that of anti-HLA antibodies than the solid phase assay (SPA) or panel reactive antibody (PRA) assay. CONCLUSION Quantitative analysis using FCXM-MESF assay accurately reflected the clinical as well as pathological aspects, and may serve as a useful guide for the selection of appropriate anti-rejection therapy. PURPOSE Genetic variations in DNA damage repair (DDR) genes may influence radiation therapy (RT)-induced acute normal tissue toxicity in patients with breast cancer. this website Identifying an individual or multiple single-nucleotide polymorphisms (SNPs) associated with RT-induced early adverse skin reactions (EASR) is critical for precision medicine in radiation oncology. METHODS AND MATERIALS At the completion of RT, EASR was assessed using the Oncology Nursing Society scale (0-6) in 416 patients with breast cancer, and Oncology Nursing Society score ≥4 was considered RT-induced EASR. PLINK set-based tests and subsequent individual SNP association analyses were conducted to identify genes and SNPs associated with EASR among the 53 DDR genes and 1968 SNPs. A weighted polygenic risk score (PRS) model was constructed to ascertain the association between the joint effect of risk alleles and EASR. RESULTS The study population consisted of 264 Hispanic whites, 86 blacks or African Americans, 55 non-Hispanic whites, and 11 otsignificance of these predictive biomarkers. PURPOSE The standard of care in management of patients with good performance status and unresectable stage III non-small cell lung cancer (NSCLC) therapy is concurrent chemoradiation. Newer techniques such as intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) are replacing 3-dimensional conformal radiation (3DCRT) despite low-quality evidence of improved outcomes. We used population-based data to examine survival outcomes by radiation technique. METHODS AND MATERIALS A population-based retrospective cohort of patients with stage III NSCLC treated with concurrent chemoradiation from 2009 to 2017 in Ontario were identified. The primary outcome was a comparison of overall survival among 3DCRT, IMRT, and VMAT, calculated using the Kaplan-Meier method and compared using log-rank test. Cox regression was used to investigate effect of radiation type on overall survival adjusted for other covariates. RESULTS A total of 3872 patients were treated with 3DCRT (n = 1178), IMRT (n = 1847), or VMAT (n = 847). A decline in 3DCRT and increase in VMAT use were observed over time. Median survival in months was 21.2 (95% confidence interval [CI], 20.0-22.8) for 3DCRT, 23.9 (95% CI, 22.3-25.6) for IMRT, and 24.9 (95% CI, 22.5-27.4) for VMAT, but these differences were not statistically significant (P = .06). CONCLUSIONS Our study demonstrates that survival is not compromised in patients receiving IMRT or VMAT (compared with 3DCRT). Thus, given the potential dosimetric advantages associated with these techniques, VMAT and IMRT are recommended for the management of patients with stage III NSCLC. PURPOSE The aim of this study was to investigate the influence of brachytherapy technique and applicator type on target dose, isodose surface volumes, and organ-at-risk (OAR) dose. METHODS AND MATERIALS Nine hundred two patients treated with tandem/ovoids (T&O) (n = 299) and tandem/ring (T&R) (n = 603) applicators from 16 EMBRACE centers were analyzed. Patients received external beam radiation therapy and magnetic resonance imaging guided brachytherapy with dose prescription according to departmental practice. Centers were divided into 4 groups, according to applicator/technique Ovoids and ring centers treating mainly with the intracavitary (IC) technique and ovoids and ring centers treating routinely with the intracavitary/interstitial (IC/IS) technique. V85Gy EQD210, CTVHR D90% (EQD210), and bladder, rectum, sigmoid, and vaginal 5-mm lateral-point doses (EQD23) were evaluated among center groups. Differences between T&O and T&R were tested with multivariable analysis. RESULTS For similar point A doses, meanwhereas routine application of IC/IS improves target and OAR dose considerably. Patients treated with T&R show a more favorable therapeutic ratio when evaluating target, bladder/rectum doses, and V85Gy. A comprehensive view on technique/applicators should furthermore include practical considerations and clinical outcome. OBJECTIVE To understand the perceptions and support for pharmacy-based pre-exposure prophylaxis (PrEP) delivery among pharmacists and men who have sex with men (MSM). DESIGN A qualitative study from April 2017 to December 2018. SETTING AND PARTICIPANTS The researchers used purposive sampling to identify MSM participants and AIDSVu to identify pharmacists in high-human immunodeficiency virus (HIV) zip codes in the metropolitan Atlanta area. Eight MSM and 6 pharmacists consented to participate in the study. OUTCOME MEASURES Perceptions and support for PrEP delivery in pharmacies. RESULTS Both MSM and pharmacists expressed strong support for in-pharmacy PrEP screening and dissemination. MSM reported that pharmacies were more convenient and accessible compared with physician's offices. However, they also noted that privacy and training of pharmacy staff were important for them to consider being screened for PrEP in a pharmacy. Pharmacists also believed training was important and felt comfortable counseling on HIV prevention for their current patients.
