Abstract
PURPOSE/OBJECTIVE(S) Novel whole breast radiation therapy (WBRT) regimens have been recently reported with the aim of improving patient convenience while preserving local control and breast cosmesis. The UK FAST Forward trial showed that 26 Gy in 5 fx using 3D conformal WBRT was equivalent to the standard 3-week regimen. However, the use of inverse planned intensity modulated radiation therapy (IMRT) for this novel ultra-hypofractionated regimen has not been previously studied. We aim to study the patient reported quality of life (QOL) outcomes and patient satisfaction of WBRT using IMRT delivering 26 Gy in 5 fractions. MATERIALS/METHODS Patients receiving WBRT with 26 Gy in 5 fractions using IMRT at our institution from 2020 to 2022 were included. Patients were treated with 26 Gy in 5 daily fx with or without a single fx boost of 4-5.2 Gy. IMRT plans were generated using inverse planning with 2 to 3 volumetric modulated arcs (VMAT). To assess patient-reported QOL outcomes, a questionnaire was prospectively administered at 1 month post treatment and yearly thereafter including the EORTC QLQ-BR23 breast cancer module and other patient satisfaction questions. Patient assessment involved a four-point scale (not at all, a little, quite a bit, and very much; very satisfied, moderately satisfied, moderately dissatisfied, and very dissatisfied). Here, we report the 1-year patient reported acute toxicity QOL outcomes and patient satisfaction for those undergoing IMRT based WBRT. Cross-sectional analyses were used to determine the prevalence of "quite a bit" or "very much" effects versus "not at all" or "a little" effects. RESULTS A total of 96 patients were included. The median age at diagnosis was 65 years. The most common histology was invasive ductal carcinoma (53.1%). ER-positivity was found in 75.5% patients. Oncoplastic reconstruction was used in 51.0% patients. The median tumor size was 1.5 cm. There were 4/98 (4.3%) node positive patients and 22.5% received adjuvant chemotherapy. Endocrine therapy was used in 74.5% patients. A boost fraction was delivered in 95.9% patients. At the 1-year assessment, only 1/35 (2.9%), 2/35 (5.7%), and 4/35 (11.4%) patients reported "quite a bit" or "very much" breast pain, skin problems, and changes in breast appearance respectively. Additionally, 32/35 (91.4%) patients were either "very satisfied" or "moderately satisfied" with their treatment, while 32/35 (91.4%) patients reported "excellent" (n = 12) or "good" (n = 20) physical appearance of the breast. CONCLUSION WBRT using inverse planned IMRT with 26 Gy in 5 fx shows excellent patient reported QOL and patient satisfaction at 1-year post RT. Longer follow up is needed to assess the long-term toxicity, normal tissue effects, and cosmetic outcomes of IMRT based delivery of this ultra-hypofractionated regimen.

Abstract
While the number of human cases of mosquito-borne diseases has increased in North America in the last decade, accurate modeling of mosquito population density has remained a challenge. Longitudinal mosquito trap data over the many years needed for model calibration, and validation is relatively rare. In particular, capturing the relative changes in mosquito abundance across seasons is necessary for predicting the risk of disease spread as it varies from year to year. We developed a discrete, semi-stochastic, mechanistic process-based mosquito population model that captures life-cycle egg, larva, pupa, adult stages, and diapause for Culex pipiens (Diptera, Culicidae) and Culex restuans (Diptera, Culicidae) mosquito populations. This model combines known models for development and survival into a fully connected age-structured model that can reproduce mosquito population dynamics. Mosquito development through these stages is a function of time, temperature, daylight hours, and aquatic habitat availability. The time-dependent parameters are informed by both laboratory studies and mosquito trap data from the Greater Toronto Area. The model incorporates city-wide water-body gauge and precipitation data as a proxy for aquatic habitat. This approach accounts for the nonlinear interaction of temperature and aquatic habitat variability on the mosquito life stages. We demonstrate that the full model predicts the yearly variations in mosquito populations better than a statistical model using the same data sources. This improvement in modeling mosquito abundance can help guide interventions for reducing mosquito abundance in mitigating mosquito-borne diseases like West Nile virus.

Abstract
Abstract
As part of a project funded by the European Commission (EC) for the development and evaluation of multiresidue methods for analysis of drinking and related waters, 17 European laboratories evaluated a method using styrene–divinylbenzene copolymer solid-phase extraction followed by liquid chromatography with diode array detection. The main aim of the study was to evaluate whether the method meets the requirements of EC Drinking Water Directive 98/83 in terms of accuracy, precision, and detection limit for 21 pesticides according to the following requirements: limit of detection, ≤0.025 μg/L; accuracy expressed as recovery, between 75 and 125%; and precision expressed as repeatability relative standard deviation of the method, <12.5%, and as reproducibility relative standard deviation of the method, <25%. Analyses for unknown concentrations were performed with commercial bottled and tap waters. All laboratories were able to achieve detection limits of 0.01 μg/L for all pesticides except pirimicarb (0.02 μg/L). The criteria for repeatability were met for all compounds. Terbutryn in bottled water and carbendazim in tap water did not meet the criteria for reproducibility. In terms of accuracy, the method met the requirements for all pesticides in both matrixes, except for metamitron. However, several compounds (linuron, terbutryn, propazine, metobromuron, and isoproturon) showed recoveries slightly below 75%.

Abstract
AIMS To isolate micro-organisms associated with marine coastal sediments of Colombian Caribbean Sea and for evaluating its antimicrobial activity in order to identify the most active strains. METHODS AND RESULTS One hundred and four strains were isolated from sediment samples of the Colombian Caribbean Sea. First at all, an antimicrobial activity screening was made using agar well diffusion method against the pathogens: Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Candida albicans, Candida tropicalis and Pseudomonas aeruginosa. Seventeen strains showed strong antimicrobial activity and were identified as members of the Streptomyces, Micrococcus and Bacillus genera. Organic extracts were produced by liquid-liquid extraction and HPLC profiles of the most active extracts were obtained. Then, the antimicrobial activity of the extracts was evaluated with the broth microdilution test, finding antimicrobial activities superior to 90% against S. aureus MRSA and C. albicans. HPLC profiles indicated the presence of different antimicrobial compounds. CONCLUSION This study demonstrates that the microorganisms isolated from the Colombian Caribbean Sea are possible sources of antimicrobial compounds against pathogenic strains. SIGNIFICANCE AND IMPACT OF STUDY These results contribute to the knowledge of the biotechnological potential of the Colombian biodiversity for the development of pharmaceutical products that can counteract the increasing problem of pathogen resistance.

Abstract
The aim of this work is to characterize atmospheric emissions of polychlorinated dibenzo-p-dioxins (PCDDs)/polychlorinated dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (dl-PCBs) from a cement production plant where the existing clinker production line was completely replaced by a new state-of-the-art installation. The project started in April 2008 with the installation of a long-term sampling system in the stack of the clinker kiln that used petroleum coke as fuel; PCDD/PCDF and dl-PCB emissions were then evaluated for a two year period. To carry out the second part of the study, in 2010 the sampling system was moved to the new installation in which, apart from conventional fuel, recovered derived fuel (RDF) and WWTP sludge were used as alternative fuels. For both the old and new clinker kilns, PCDD/PCDF emission values were well below the limit established by the European Waste Incineration Directive 2000/76/CE (EWID) of 100 pg I-TEQ/Nm(3); values ranged from 0.43 to 2.02 and from 0.07 to 3.31 pg I-TEQ/Nm(3), respectively. dl-PCBs accounted for approximately 25% of the WHO-TEQ toxicity. These results prove that the installation is capable of reducing PCDD/PCDF and dl-PCB emissions when alternative fuels are integrated into the process. In the case of PCDDs/PCDFs, the major contributions to total TEQ were usually from 2,3,7,8-TCDD (owing to its relative abundance) and 2,3,4,7,8-PeCDF (due to its high I-TEF of 0.5); while for dl-PCBs, the major contribution was from PCB-126. The slight shift in the congener profile between the old and new installations was characterized and a regression model was proposed for dl-PCB emissions depending on the RDF flow rate in the clinker.

Abstract
OBJECTIVES To review important patient safety practices for evidence of effectiveness, implementation, and adoption. DATA SOURCES Searches of multiple computerized databases, gray literature, and the judgments of a 20-member panel of patient safety stakeholders. REVIEW METHODS The judgments of the stakeholders were used to prioritize patient safety practices for review, and to select which practices received in-depth reviews and which received brief reviews. In-depth reviews consisted of a formal literature search, usually of multiple databases, and included gray literature, where applicable. In-depth reviews assessed practices on the following domains: • How important is the problem? • What is the patient safety practice? • Why should this practice work? • What are the beneficial effects of the practice? • What are the harms of the practice? • How has the practice been implemented, and in what contexts? • Are there any data about costs? • Are there data about the effect of context on effectiveness? We assessed individual studies for risk of bias using tools appropriate to specific study designs. We assessed the strength of evidence of effectiveness using a system developed for this project. Brief reviews had focused literature searches for focused questions. All practices were then summarized on the following domains: scope of the problem, strength of evidence for effectiveness, evidence on potential for harmful unintended consequences, estimate of costs, how much is known about implementation and how difficult the practice is to implement. Stakeholder judgment was then used to identify practices that were "strongly encouraged" for adoption, and those practices that were "encouraged" for adoption. RESULTS From an initial list of over 100 patient safety practices, the stakeholders identified 41 practices as a priority for this review: 18 in-depth reviews and 23 brief reviews. Of these, 20 practices had their strength of evidence of effectiveness rated as at least "moderate," and 25 practices had at least "moderate" evidence of how to implement them. Ten practices were classified by the stakeholders as having sufficient evidence of effectiveness and implementation and should be "strongly encouraged" for adoption, and an additional 12 practices were classified as those that should be "encouraged" for adoption. CONCLUSIONS The evidence supporting the effectiveness of many patient safety practices has improved substantially over the past decade. Evidence about implementation and context has also improved, but continues to lag behind evidence of effectiveness. Twenty-two patient safety practices are sufficiently well understood, and health care providers can consider adopting them now.

Abstract
The aim of this work is to evaluate the performance of a continuous monitoring system for the analysis of the mass concentration of PCDD/Fs from stationary sources. Data was acquired from a modern, state of the art, hazardous waste thermal treatment plant for a period of more than 2 years using a commercial available continuous monitoring system. The study consisted of a total of 16 samples, collected in periods from 1 week to 2 months resulting in an average of 360 m³ sampled flue gas per sample. The study showed the system was able to confirm that for a period of more than 2 years the plant was complying with the limit of 0.1 ng I-TEQ/Nm(3). In addition, the data showed the typical fingerprint of such installations which is useful for example in impact studies. Long-term samples were compared to five short-term samples (6 h) collected every 6 months during the study period. Principal component analysis was applied to PCDD/Fs obtained data as useful statistical tool to find out trends and similarities between different samples. Improvement in terms of representativeness of data was achieved through continuous assessment since the starts of the project. The obtained data was further used to determine the emission factor for this activity and the total annual PCDD/Fs release to the atmosphere.

Abstract
Standing subjects were unexpectedly pulled forward to identify a threshold boundary that evokes stepping in terms of the size of the pull relative to the base of support (BoS). Performances in a range of sensorimotor tests were correlated with the threshold boundary parameters. Younger and older subjects were studied to identify age-related changes in stepping and the threshold boundaries. The threshold boundary had a forward limit (T(L)) that, when crossed, always made subjects step no matter how slowly they were pulled. As velocity increased, the threshold position that produced a step shifted nearer to the ankles. Eventually a pull velocity was reached above which velocity had no further effect and a position threshold (T(H)) was identified behind which subjects never stepped. Thus the position threshold boundary for stepping is a posterior-going sigmoidal function of perturbation velocity. Older subjects stepped more than the young (69% vs. 40% of trials). For the older subjects, T(L) (91% vs. 107% BoS) and T(H) (59% vs. 72% BoS) were closer to the ankles, and the transition between T(L) and T(H) occurred at lower velocities (96% vs. 121% BoS.s(-1)). Across the entire study population many sensorimotor factors were associated with T(L) and T(H). However, these associations were not present when age was removed as a factor. Thus, although the older subjects use protective stepping more often, this cannot be attributed directly to the sensorimotor factors tested here. It can be explained by stepping as a triggered response to the perturbation event rather than later sensory input about body movement.

Abstract
There has been increased concern over health effects related to potential exposure of building occupants to bioaerosols. We report the case of a worker with a respiratory illness related to bioaerosol exposure in a water-damaged building with extensive fungal contamination. We performed environmental tests to evaluate potential exposure to fungi, and we used mycotoxin-specific IgG antibody in serologic studies in the attempt to evaluate exposure to mycotoxins. Extensive fungal contamination was documented in many areas of the building. Penicillium, Aspergillus, and Stachybotrys species were the most predominant fungi found in air sampling. Our serologic test was not useful in differentiating workers who were probably occupationally exposed to mycotoxins from those who were not; however, it did yield evidence that individuals may make specific IgG antibodies to macrocyclic tricothecene mycotoxins. Further research is needed concerning health effects related to bioaerosol exposures, particularly regarding markers of exposure to specific fungi that may produce mycotoxins. In the absence of clinical tools specific for evaluation of mycotoxin-related illness, a systematic clinical approach for evaluating persons with suspected building-related respiratory illness is warranted.

Abstract
Resonance regions similar to the Arnol'd tongues found in single oscillator frequency locking are observed in experiments using a spatially extended periodically forced Belousov-Zhabotinsky system. We identify six distinct 2:1 subharmonic resonant patterns and describe them in terms of the position-dependent phase and magnitude of the oscillations. Some experimentally observed features are also found in numerical studies of a forced Brusselator reaction-diffusion model.

Abstract
Experimental autoimmune myasthenia gravis (EAMG) is a T cell-dependent, Ab-mediated autoimmune disease induced in rats by a single immunization with acetylcholine receptor (AChR). Although polarized Th1 responses have been shown to be crucial for the development of mouse EAMG, the role of Th cell subsets in rat EAMG is not well established. In the present work we show that while the incidence and severity of EAMG are similar in Lewis (LEW) and Brown-Norway (BN) rats, strong differences are revealed in the immune response generated. Ag-specific lymph node cells from LEW rats produced higher amounts of IL-2 and IFN-gamma than BN lymph node cells, but expressed less IL-4 mRNA. IgG1 and IgG2b anti-AChR isotype predominated in BN and LEW rats, respectively, confirming the dichotomy of the immune response observed between the two strains. Furthermore, although IL-12 administration or IFN-gamma neutralization strongly influenced the Th1/Th2 balance in BN rats, it did not affect the disease outcome. These data demonstrate that a Th1-dominated immune response is not necessarily associated with disease severity in EAMG, not only in rats with disparate MHC haplotype but also in the same rat strain, and suggest that in a situation where complement-fixing Ab can be generated as a consequence of either Th1- or Th2-mediated T cell help, deviation of the immune response will not be an adequate strategy to prevent this Ab-mediated autoimmune disease.

Abstract
STUDY OBJECTIVE To determine the distribution and concentration of aerosol particles caused by an ultrasonic (Harmonic) scalpel during simulated surgical use. DESIGN Prospective experimental analysis (Canadian Task Force classification II-1). SETTING Standard operating room. MATERIALS Lean pork, lean beef, water, and blood, and the Harmonic scalpel with ball, curved scalpel, and cutting tips. INTERVENTIONS Real-time sampling of airborne aerosols was performed over 6-second sampling periods. MEASUREMENTS AND MAIN RESULTS Blood and tissue particles increased significantly during use of the Harmonic scalpel. Local exhaust evacuation methods diminished these concentrations. CONCLUSIONS The Harmonic scalpel causes formation of bioaerosols that are composed of material of respirable size. When this device is used, a local exhaust system or smoke-evacuation method should be activated to reduce exposure to blood, blood by-products, and potentially infectious materials.

Abstract
Airborne fungi have been postulated as a cause of symptoms among office workers. Using the MAST chemiluminescent system, this study evaluated 36 IgG and 36 IgE antibody levels in 47 office workers from an area with elevated airborne fungal concentrations and 44 office workers from an otherwise similar area with lower airborne fungal exposure. No difference was found in IgG antibody to fungi between the lower and higher exposure areas, but high IgG antibody to one or more of the fungi studied was detected in 67% of all the workers tested. IgE antibody to one or more antigens was detected in 40% of the participants. Workers who reported atopic symptoms (sneezing, runny nose, and itchy eyes) or "sick building" symptoms (any three of the following temporally related to work: headache, fatigue, stuffy nose, irritated eyes, or sore throat) were more likely to have one positive IgE antibody test. Type I hypersensitivity to aeroallergens besides fungi may play a role in some symptoms reported by some participants in this office building.

Abstract
Alu sequences represent the largest family of short interspersed repetitive elements (SINEs) in humans with 500 000 copies per genome. Recently, one Alu subfamily was found to be human specific (HS). We originally described the use of polymorphis HS Alu insertions as a tool in population studies and recently as tools in DNA fingerprinting and forensic analysis. In this report, we will use this simple polymerase chain reaction (PCR) base technique for the detection of HS Alu insertion polymorphisms. We will test the resolving power of this DNA profiling approach in both population genetics and paternity assessment. At the population level, we will describe the genotypic distribution of five polymorphic Alu insertions among 3 populations from the American continent, one of African origin, the other two Amerindians. Insight into their relationships will be provided. At the family level, we will examine one European American family of seven individuals and the same pedigree will also be characterized by way of the two systems currently and widely used to ascertain paternity: PCR-sequence specific oligonucleotide probe hybridization (PCR-SSO) and PCR-restriction fragment length polymorphism (PCR-RFLP) of human leucocyte antigen (HLA) class II molecules, and a standard RFLP protocol used in forensic casework and paternity studies. The importance and strengths of the methods as well as its perspectives for future use in filiation studies will be evaluated.

Abstract
The majority of astroglia develop postnatally in rats. GFAP (glial fibrillary acidic protein)-immunoreactivity appears mainly during the 2nd and 3rd postnatal weeks throughout the brain. Hypothyroidism inhibits, among others, the cell proliferation, maturation, and migration of neurons. However, hardly any data on the effect of hypothyroidism on GFAP-immunoreactivity are available in the literature. In our experiments, thyroidectomy was performed between the 3rd and 5th postnatal days. Operated and control animals from the same litter were perfused transcardially and processed for immunohistochemistry in parallel after 2, 3, and 4 wk. On the basis of serial sections, the development of GFAP-immunoreactivity was not generally affected by hypothyroidism. We could observe only two phenomena that showed a tendency of retardation in the operated animals: (1) the decrease of the strong GFAP-immunopositivity of white matter tracts (for example, internal capsule and pyramidal tract) and (2) the gradual disappearance of the GFAP-immunoreactive radial fibers (for example, in the neocortex, in the olfactory bulb, and around the 3rd ventricle).
