The recognition of occupational carcinogens is important for primary prevention, compensation and surveillance of exposed workers, as well as identifying causes of cancer in the general population. This study updates previously published lists of known occupational carcinogens while providing additional information on cancer type, exposure scenarios and routes, and discussing trends in the identification of carcinogens over time. Data were extracted from International Agency for Research on Cancer (IARC) Monographs covering the years 1971-2017, using specific criteria to ensure occupational relevance and provide high confidence in the causality of observed exposure-disease associations...

PURPOSE: The use of ultrasound imaging is not widespread in prostate cancer radiotherapy workflows, despite several advantages (e.g. allowing real-time volumetric organ tracking). This can be partially attributed to the need for a trained operator during acquisition and interpretation of the images. We introduce and evaluate an algorithm that can propose a patient-specific transperineal ultrasound probe setup, based on a CT scan and anatomical structure delineations. The use of this setup during the simulation and treatment stage could improve usability of ultrasound imaging for relatively untrained operators (radiotherapists with less than one year experience with ultrasound)...

A voluntary partial-body donor (U.S. Transuranium and Uranium Registries Case 0785) was accidentally exposed to Pu via inhalation and wounds. This individual underwent medical treatment including wound excision and extensive chelation treatment with calcium ethylenediaminetetraacetic acid and calcium diethylenetriaminepentaacetic acid. Approximately 2.2 kBq of Pu was measured in the wound site 44 y after the accident. Major soft tissues and selected bones were collected at autopsy and radiochemically analyzed for Pu, Pu, and Am...

OBJECTIVE: To examine dose-response relationships between internal uranium exposures and select outcomes among a cohort of uranium enrichment workers. METHODS: Cox regression was conducted to examine associations between selected health outcomes and cumulative internal uranium with consideration for external ionizing radiation, work-related medical X-rays and contaminant radionuclides technetium (99 Tc) and plutonium (239 Pu) as potential confounders. RESULTS: Elevated and monotonically increasing mortality risks were observed for kidney cancer, chronic renal diseases, and multiple myeloma, and the association with internal uranium absorbed organ dose was statistically significant for multiple myeloma...

For more than half a century, stereotactic neurosurgical procedures have been available to treat patients with severe, debilitating symptoms of obsessive-compulsive disorder (OCD) that have proven refractory to extensive, appropriate pharmacological, and psychological treatment. Although reliable predictors of outcome remain elusive, the establishment of narrower selection criteria for neurosurgical candidacy, together with a better understanding of the functional neuroanatomy implicated in OCD, has resulted in improved clinical efficacy for an array of ablative and non-ablative intervention techniques targeting the cingulum, internal capsule, and other limbic regions...

Selective internal radiation therapy using Y spheres is a treatment option for patients with primary or secondary liver cancer. To avoid complications, screening using Tc macroaggregated albumin is performed to identify lung shunting and extrahepatic depositions. For the latter, deposition after the anterior abdominal wall is frequently attributed to a patent falciform artery, although the vessel itself is rarely visible on SPECT/CT scans. We demonstrate that retrospective SPECT/MRI fusion clearly attributes the nuclide accumulation to a patent falciform artery...

INTRODUCTION: Accurate staging of patients with prostate cancer is important for therapeutic decision making. Relapse following surgery or radiotherapy of curative intent is not uncommon and, in part, represents a failure of staging with current diagnostic imaging techniques to detect disease spread. Prostate-specific-membrane-antigen (PSMA) positron emission tomography / computed tomography (PET/CT) is a new whole body scanning technique that enables visualisation of prostate cancer with high contrast...

Relapsed and refractory Hodgkin lymphoma (HL) challenges clinicians to devise treatment strategies that are effective and safe. This problem is particularly prominent in an era when de-escalation trials are designed to minimize therapeutic toxicities in both early- and advanced-stage disease. Radiation therapy is the single most effective treatment modality for HL, and its integration into salvage regimens, or its independent use in select patients, must be understood to maximize our success in treating these patients...

A three-dimensional transformation optics method, leading to homogeneous materials, applicable to any non-Cartesian coordinate systems or waveguides/objects of arbitrary cross-sections is presented. Both the conductive boundary and internal material of the desired device is determined by the proposed formulation. The method is applicable to a wide range of waveguide, radiation, and cloaking problems, and is demonstrated for circular waveguide couplers and an external cloak. An advantage of the present method is that the material properties are simplified by appropriately selecting the conductive boundaries...

PURPOSE: The optimum adjuvant treatment for Stage II endometrial cancer patients is unknown. External beam radiation therapy (EBRT) is often considered the standard of care; however, retrospective series suggest that brachytherapy (BT) alone may be sufficient for selected patients. As randomized data are lacking, we used a large database to explore this question. METHODS AND MATERIALS: The National Cancer Data Base was queried for patients with pathologic International Federation of Gynecology and Obstetrics Stage II disease...

BACKGROUND: In Finland, selective internal radiation therapy (SIRT) is at present the preferred first-line loco-regional therapy for uveal melanoma patients with hepatic metastases not suitable for surgery. We retrospectively evaluate the outcome and safety of SIRT in this group of patients. MATERIAL AND METHODS: Yttrium-90 microspheres were delivered via the hepatic artery into the circulation of metastases from uveal melanoma in 18 patients with a predicted life expectancy of more than three months in three Finnish tertiary referral centers between November 2010 and December 2015...

INTRODUCTION: Male stress urinary incontinence (SUI) after radical prostatectomy (RP) is common. The surgical standard of care traditionally has been placement of an artificial urinary sphincter (AUS) but since its introduction the transobturator male sling has been shown to have particular unique advantages. Our aim was to assess outcomes of a consecutive series of suburethral sling insertions in men presenting with all degrees of post RP SUI. MATERIALS AND METHODS: A consecutive cohort of men undergoing AdVance sling insertion following RP were studied...

The structural and photophysical properties of well-selected tetradentate Pt(II) frames including Pt(ppzOppz), Pt(ppzOpopy), Pt(ppzOczpy) and Pt(czpyOczpy) have been experimentally and theoretically explored in detail. Single crystal diffraction measurements of the four complexes provided accurate bond lengths, angles and other integrate structural information. Their characteristic electrochemical and photophysical information clearly revealed internal electronic levels in ground and excited states. Time dependent density functional theory (TD-DFT) uncovered electron distributions in transition process of excitation (S0→S1) and radiation (S1→T1→S0)...

The International Commission on Radiological Protection (ICRP) mandated a task group (Task Group 64) to review recently published epidemiological studies related to cancer risk and incorporated alpha emitters, and to evaluate whether the results might consolidate or challenge assumptions underlying the current radiation protection system. Three major alpha emitters were considered: radon and its decay products, plutonium, and uranium. Results came mainly from cohorts of workers, while for radon, major studies of the general population contributed to a better understanding of the risk of lung cancer at low and chronic exposure...

The response of DNA and RNA bases to ultraviolet (UV) radiation has been receiving increasing attention for a number of important reasons: (i) the selection of the building blocks of life on an early earth may have been mediated by UV photochemistry, (ii) radiative damage of DNA depends critically on its photochemical properties, and (iii) the processes involved are quite general and play a role in more biomolecules as well as in other compounds. A growing number of groups worldwide have been studying the photochemistry of nucleobases and their derivatives...

Shivani Sud, Toni Roth, Ellen Jones
Purpose: Intra-vaginal packing is used to fix the applicator and displace organs at risk (OAR) during high-dose-rate intracavitary tandem and ovoid brachytherapy (HDR-ICB). We retain the speculum from applicator placement as a dual-function bladder and rectum retractor during treatment. Our objective is to review salient techniques for OAR displacement, share our packing technique, and determine the reduction in dose to OAR and inter-fraction variability of dose to OAR, associated with speculum-based vaginal packing (SBVP) in comparison to conventional gauze packing during HDR-ICB...
