Social work regulatory rules and practices should balance the social values of promoting consumer safety and workforce equity. As the two values often compete, the balancing act should be guided by empirical evidence about the effects of regulations on consumers and the workforce. Unfortunately, however, empirical studies investigating the relationships between various regulatory rules and practices and consumer safety and workforce equity are rare in the existing literature. This paper identifies critical gaps in the current knowledge base and proposes a series of future research agendas that call for empirical evidence, including detailed data on jurisdictional regulatory rules and practices, the measures of consumer safety, and licensed social workers' demographic, employment, and practice characteristics. The paper concludes by calling out to all social work stakeholders about the need for empirical evidence on the effects of social work regulatory rules and practices. [ABSTRACT FROM AUTHOR]

BACKGROUND: The ubiquitous use of social media places adolescents at high risk for cyberincivility (disrespectful, insensitive, or disruptive online behaviors). Adolescents who experience cyberincivility can have mental health issues including depression and suicidal ideation. However, no reviews synthesized findings from qualitative studies on cyberincivility among adolescents, which was the aim of this review. METHODS: Eleven articles were extracted from MEDLINE, Embase, PsycINFO, ERIC, and Education Full Text. Study qualities were assessed using the JBI Critical Appraisal Checklist. A meta‐ethnographic framework guided the thematic analysis. RESULTS: Five themes were identified: forms of cyberincivility, platforms used for cyberincivility, perceptions and understanding of cyberincivility, adverse impact on health, and perceptions of seeking support. Social media was often used for cyberincivility, and common forms of cyberincivility included impersonation, aggressive verbal behaviors, and social exclusion. Adolescents perceived cyberincivility as persistent and relentless, with severe health impacts including depression, but they hesitate to seek support. CONCLUSIONS: Considering the negative impact of cyberincivility on adolescents' physical and mental well‐being, it is important to develop anti‐cyberincivility programs in schools. Schools have opportunities to efficiently reach both perpetrators and victims of cyberincivility with anti‐cyberincivility programs rooted in trust building and engagement from family, community, and peers.

Background Skin neglected tropical diseases (NTDs) produce signs and symptoms that are often physically challenging, stigmatizing and have a negative impact on the mental wellbeing of people affected. In the Democratic Republic of Congo (DRC), little is known about the mental wellbeing experiences of people affected by skin NTDs and support is lacking. We collaborated with ongoing NTD programs, the Ministry of Health and people affected to evidence experiences and opportunities for change and co-developed a mental wellbeing support package for people affected and local health system actors. Methods This implementation research study used the photovoice method alongside key-informant interviews to evidence mental wellbeing challenges in people affected by skin NTDs and explore opportunities for change. These were used to co-develop a skin NTD mental wellbeing support package with people affected, community members and local health system actors through a participatory workshop. Results Stigma, discrimination, decreased livelihoods and mental wellbeing challenges were evidenced by people affected by skin NTDs, their communities and health system actors. Participants identified and co-established community-led peer support groups, strengthened with basic knowledge on psychosocial support, and income-generating or recreational initiatives to support mental wellbeing of people affected by skin NTDs. Conclusions Co-developing a support package with persons affected, community members and health system actors is a step towards holistic care for people affected by skin NTDs and promotes uptake and ownership of intervention components. Contexte Les maladies tropicales négligées (MTN) cutanées produisent des signes et des symptômes qui sont souvent difficiles à supporter physiquement, ils sont également stigmatisants et ont un impact négatif sur le bien-être mental des personnes touchées. En République Démocratique du Congo (RDC), on sait peu de choses sur le bien-être mental des personnes atteintes de MTN cutanées, et le soutien fait défaut. Nous avons collaboré avec les programmes de lutte contre les MTN en cours, le ministère de la santé et les personnes touchées pour mettre en évidence les expériences et les possibilités de changement, et nous avons élaboré un programme de soutien au bien-être mental pour les personnes touchées et les acteurs du système de santé local. Méthodes utilisées Cette étude de recherche sur la mise en œuvre a utilisé la méthode photovoice, ainsi que des entretiens avec des informateurs clés, afin de mettre en évidence les problèmes de bien-être mental des personnes touchées par les MNT cutanées. Ces éléments ont été utilisés pour élaborer un programme de soutien au bien-être mental des MNT cutanées avec les personnes concernées, les membres de la communauté et les acteurs du système de santé local dans le cadre d'un atelier participatif. Résultats La stigmatisation, la discrimination, la diminution des moyens de subsistance et les problèmes de bien-être mental ont été mis en évidence par les personnes atteintes de MTN cutanées, leurs communautés et les acteurs du système de santé. Les participants ont identifié et mis en place des groupes communautaires de soutien par les pairs, renforcés par des connaissances de base en matière de soutien psychosocial, et des initiatives génératrices de revenus/récréatives pour soutenir le bien-être mental des personnes touchées par les MTN cutanées. Conclusions L'élaboration d'un ensemble de mesures de soutien en collaboration avec les personnes concernées, les membres de la communauté et les acteurs du système de santé, constitue une étape vers une prise en charge holistique des personnes atteintes de MNT cutanées et favorise l'adoption et l'appropriation des composantes de l'intervention. Antecedentes Las enfermedades tropicales desatendidas (ETDs) cutáneas producen signos y síntomas que a menudo suponen un reto físico, estigmatizan y tienen un impacto negativo en el bienestar mental de las personas afectadas. En la República Democrática del Congo (RDC), se sabe poco sobre las experiencias de bienestar mental de las personas afectadas por ETDs cutáneas, y falta apoyo. Colaboramos con los programas en curso sobre las ETDs, el Ministerio de Sanidad y las personas afectadas para poner de manifiesto las experiencias y las oportunidades de cambio, y desarrollamos de manera conjunta un paquete de apoyo al bienestar mental para las personas afectadas y los agentes del sistema sanitario local. Métodos Este estudio de investigación utilizó el método fotovoz, junto con entrevistas a informantes clave, para poner de manifiesto los desafíos de bienestar mental de las personas afectadas por ETDs cutáneas y explorar las oportunidades de cambio. Estos datos se utilizaron para desarrollar un paquete de apoyo al bienestar mental de manera conjunta con las personas afectadas por las ETDs cutáneas, los miembros de la comunidad y los actores del sistema sanitario local a través de un taller participativo. Resultados El estigma, la discriminación, la disminución de los medios de subsistencia y los problemas de bienestar mental fueron evidenciados por las personas afectadas por ETD cutáneas, sus comunidades y los agentes del sistema sanitario. Los participantes identificaron y establecieron conjuntamente grupos de apoyo entre pares dirigidos por la comunidad, fortalecidos con conocimientos básicos sobre apoyo psicosocial e iniciativasrecreativas y generadoras de ingresos para apoyar el bienestar mental de las personas afectadas por las ETD cutáneas. Conclusións El desarrollo conjunto de un paquete de medidas de apoyo con las personas afectadas, los miembros de la comunidad y los actores del sistema sanitario es un paso hacia la atención holística de las personas afectadas por las NTDs a y promueve la adopción y apropiación de los componentes de la intervención.

Background Worldwide, persons affected by skin Neglected Tropical Diseases (NTDs) may experience stigma and discrimination, which could lead to impaired societal functioning and poor mental wellbeing. Evidence of comorbidity of NTDs and mental health conditions is dominated by Leprosy, largely lacking in post-conflict areas, and rarely disaggregated by sex. Methods This cross-sectional survey is the first to explore depression, anxiety, stigma, and quality of life amongst people affected by Lymphatic Filariasis, Buruli Ulcer, Onchocerciasis or Leprosy in the Democratic Republic of the Congo. After a census through active case identification, the survey was completed by 118 persons (response rate 94.4%). Results In total, 58.3% of men and 80.0% of women screened positive for major depressive disorder (PHQ-9). Symptoms indicative of generalised anxiety disorder (GAD-7) were displayed by 54.8% of men and 62.2% of women. Being female, having a disability, experiencing stigma and lower physical quality of life were predictors of depression. Anxiety was predicted by age, physical quality of life, disability (for men only) and environmental quality of life (for women only). Conclusions Integrated, intersectoral and gender-sensitive initiatives are needed to respond to the many biopsychosocial challenges that persons affected face. Contexte Dans le monde entier, les personnes atteintes de maladies tropicales négligées (MTN) peuvent faire l'objet d'une stigmatisation et d'une discrimination, ce qui peut entraîner une altération du fonctionnement de la société et un mauvais bien-être mental. Les preuves de la comorbidité des MTN et des troubles de la santé mentale sont dominées par la lèpre, manquent largement dans les zones post-conflit et sont rarement ventilées par sexe. Méthodes utilisées Cette enquête transversale est la première à explorer la dépression, l'anxiété, la stigmatisation et la qualité de vie chez les personnes atteintes de filariose lymphatique, d'ulcère de Buruli, d'onchocercose ou de lèpre en République démocratique du Congo. Après un recensement par identification active des cas, 118 personnes ont répondu à l'enquête (taux de réponse 94,4%). Résultats Au total, 58,3% des hommes et 80,0% des femmes ont été dépistés positifs pour un trouble dépressif majeur (PHQ-9). Des symptômes indiquant un trouble anxieux généralisé (GAD-7) ont été observés chez 54,8 % des hommes et 62,2 % des femmes. Le fait d'être une femme, d'avoir un handicap, d'être stigmatisé et d'avoir une qualité de vie physique inférieure était un facteur prédictif de la dépression. L'anxiété était prédite par l'âge, la qualité de vie physique, le handicap (pour les hommes uniquement) et la qualité de vie environnementale (pour les femmes uniquement). Conclusions Des initiatives intégrées, intersectorielles et sensibles au genre sont nécessaires pour répondre aux nombreux défis biopsychosociaux auxquels sont confrontées les personnes touchées. Antecedentes En todo el mundo, las personas afectadas por Enfermedades Tropicales Desatendidas (ETD) cutáneas pueden sufrir estigmatización y discriminación, lo que podría conducir a un deterioro del funcionamiento social y a un bienestar mental deficiente. La evidencia científica sobre la comorbilidad de las ETD y las afecciones mentales está dominada por la lepra, en general insuficiente en zonas post-conflicto y rara vez se desglosan por sexo. Métodos Esta encuesta transversal es la primera que explora la depresión, la ansiedad, el estigma y la calidad de vida entre las personas afectadas por la filariasis linfática, la úlcera de Buruli, la oncocercosis o la lepra en la República Democrática del Congo. Tras un censo mediante identificación activa de casos, la encuesta fue completada por 118 personas (tasa de respuesta del 94,4%). Resultados En total, el 58,3% de los hombres y el 80,0% de las mujeres arrojaron resultados positivos para el trastorno depresivo mayor (PHQ-9). El 54,8% de los hombres y el 62,2% de las mujeres presentaban síntomas indicativos de trastorno de ansiedad generalizada (TAG-7). Ser mujer, tener una discapacidad, sufrir estigmatización y una menor calidad de vida física fueron factores predictivos de la depresión. La edad, la calidad de vida física, la discapacidad (sólo en el caso de los hombres) y la calidad de vida ambiental (sólo en el caso de las mujeres) fueron factores predictivos de la ansiedad. Conclusiones Se necesitan iniciativas integradas, intersectoriales y con perspectiva de género para responder a los numerosos retos biopsicosociales a los que se enfrentan las personas afectadas.

Objective : The social work profession pays less than other occupations with similar educational and training requirements and still penalizes women with lower pay. However, licensure has the potential to improve the earnings of social workers and affect gender disparity in earnings among licensed social workers. This study aims to estimate (a) the license-related earnings premiums of college-educated social workers and (b) the gender effect on earnings among licensed social workers. Method : We used a nationally representative sample of 1,515 U.S. social workers from the 2015–2019 Current Population Survey and conducted marginal treatment effect analyses. Results : The average license-related weekly earnings premium was $110 for all social workers and $128 for licensed social workers. Gender disparity in earnings was concentrated among licensed social workers. Conclusions : The size of license-related earnings premiums for social workers is within the range of the premiums reported in the literature. More studies are needed to identify mechanisms that perpetuate gender disparity in earnings among licensed social workers. [ABSTRACT FROM AUTHOR]

This paper provides an overview of the limitations in the current state-based licensure system for social worker practitioners, clients, and regulators that calls for an interstate solution such as a licensure compact. It also reviews the models of interstate licensure compacts from other healthcare professions and draws lessons critical for the implementation of the emerging Social Work Licensure Compact. It further reviews empirical evidence on interstate compacts, available only in the nursing literature, and reports that the nurse licensure compact may be related to improvement in nurses' geographic mobility and public safety but a reduction in nurses' wages and employment. Building upon these reviews, this paper proposes that social work stakeholders and scholars should focus on monitoring how and to what extent the compact will affect (1) practitioners' practice mobility and labor market outcomes, (2) public safety and access to social work services, and (3) regulatory efficiency and standardization in the future.

Purpose : This article intends to review the literature to address the concern that prevalent licensure exemptions in social work undermine public safety. Methods : It reviews (1) the rationales for licensure exemptions, (2) the effects of exemptions on the public and the social work workforce, and (3) critical gaps in the extant evidence to recommend future research agendas to fill the gaps. Results : A review of the literature revealed that concerns about duplicated regulations and potential labor shortages justified licensure exemptions but with little empirical evidence. Limited evidence was found to support the claim that exemptions minimize the effects of licensure. Extant evidence, albeit scant, implies that licensure may not eliminate lower-quality services but benefit incumbent social workers with higher earnings. Conclusions : Recognizing the gaps in the literature, it recommends empirical research and discusses available data to assess the effects of exemptions on public safety and socioeconomic (in)equity within the workforce.

Background: Lifestyle (dietary and/or physical activity [PA]) modification is recommended as first-line therapy to manage polycystic ovary syndrome (PCOS). Current recommendations are based on healthy lifestyle practices for the general public since evidence for unique lifestyle approaches in PCOS is limited and low quality.Objective and Rationale: We aimed to synthesize evidence on dietary and PA behaviors between women with PCOS and those without PCOS. Primary outcomes were overall diet quality, total energy intake and total PA, and secondary outcomes included macronutrients, micronutrients, food groups, foods, glycemic indices, sedentary time and sitting levels. We conducted this work to identify any unique lifestyle behaviors in women with PCOS that could underlie the propensity of weight gain and obesity in PCOS and be targeted for precision nutrition and PA interventions. These findings could be used to inform future practice recommendations and research that more effectively address complications (weight gain, obesity, diabetes, infertility, cardiovascular disease and mental health) in this high-risk population.Search Methods: Databases of MEDLINE, Web of Science, Scopus and CINAHL were searched until 15 February 2022 to identify observational studies documenting dietary and PA behaviors between women with PCOS and without PCOS (Controls). Studies on children, adolescents (<18 years), pregnant or menopausal-aged women (>50 years) were excluded. Data were pooled by random-effects models and expressed as (standardized) mean differences (MD) and 95% CIs. The risk of bias was assessed by the Newcastle-Ottawa scale (NOS).Outcomes: Fifty-four studies (N = 39 471 participants; [n = 8736 PCOS; 30 735 Controls]) were eligible (96%; [52/54] NOS scores ≥ 7). Women with PCOS had higher cholesterol (MD: 12.78, 95% CI: 1.48 to 24.08 mg/day; P = 0.03; I2 = 19%), lower magnesium (MD: -21.46, 95% CI: -41.03 to -1.91 mg/day; P = 0.03; I2 = 76%), and a tendency for lower zinc (MD: -1.08, 95% CI: -2.19 to -0.03 mg/day; P = 0.05; I2 = 96%) intake, despite lower alcohol consumption (MD: -0.95, 95% CI: -1.67 to 0.22 g/day; P = 0.02; I2 = 0%) versus Controls. Also, women with PCOS had lower total PA (standardized mean difference: -0.38, 95% CI: -0.72 to 0.03; P = 0.03; I2 = 98%). Conversely, energy, macronutrients (carbohydrate, fat, protein, fiber), micronutrients (folic acid, iron, calcium, sodium), glycemic index and glycemic load were similar (all: P ≥ 0.06). Most eligible studies reported lower total adherence to healthy eating patterns or poorer consumption of major food groups (grains, fruits, vegetables, proteins, seeds, nuts, dairy) in women with PCOS, as described narratively since variable study methodology did not permit meta-analyses.Wider Implications: Collective evidence supports that women with PCOS have a lower overall diet quality, poorer dietary intakes (higher cholesterol, lower magnesium and zinc) and lower total PA, despite lower alcohol consumption versus those without PCOS. Considerable heterogeneity among studies reinforces the need for research to address any relative contributions of other factors (e.g. genetic, metabolic or sociodemographic) to the observed differences. These clarifications may contribute to future evidence-based guideline recommendations on monitoring and managing PCOS in the era of precision lifestyle medicine. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed at examining how racial disparities in social workers' licensing rates are explained by the major sources of the disparities: racial differences in educational eligibilities, the field of practice, and demographic vulnerabilities of social workers. Methods: Drawing a nationally representative sample of 3990 social workers from the Current Population Survey, this study tested how the probabilities of their licensing were explained by the major sources of racial disparities. Results: For master's level social workers, African American–White differences in the field of practice and the type of employers explained away the disparity in required licensing rates. The Hispanic–White and other race–White disparities were largely due to non-White social workers' limited educational eligibilities and the states of residence that might have imposed varying occupational regulations. Conclusions: As licensing disparities reflect socioeconomic injustice that confronts many non-White social workers, they call for more purposeful research and interventions within the profession.

Background and Objectives Although studies pointed out that the number of personal care aides (PCAs) at risk of being in informal employment arrangements is sizeable, little is known about its size and worker characteristics. This study aimed to estimate the share of PCAs working as household employees or independent contractors. It also aimed to compare their basic job characteristics against the job characteristics of those working as agency and government employees. Research Design and Methods Using data from the 2014–2018 American Community Surveys, a sample of 43,287 PCAs working for pay in the home- and community-based service (HCBS) industry was identified, and their job characteristics—full-time weekly work (i.e. working at least 35 hours per week), year-round work (i.e. working at least 50 weeks a year), and annual gross earning—were analyzed by their employment arrangement. Results Analyses found that (a) close to a quarter of aides in the HCBS industry work as household employees or independent contractors while their share in the workforce varies by state and that (b) the work hours and earnings of full-time year-round working household employees or independent contractors are greater than those of their agency counterparts. The results shed light on why some aides may work as household employees or independent contractors. Discussion and Implications The presence of household employees and independent contractors has important implications for PCAs' job characteristics and labor shortage in the U.S. home care industry. Considering the potentially negative consequences for both the aides' economic security and the quality of care that consumers can receive, attention should be paid to ways to bring the aides into a more formal employment arrangement.

This study drew a nationally representative sample of U.S. low-wage hourly workers subject to the minimum wage mandates from the 2008 Survey of Income and Program Participation (SIPP) and estimated the prevalence of minimum wage violations in two unique ways. The incidence of experiencing violations was also modeled to examine the relative importance of workers' vulnerabilities and their employment characteristics in determining the incidence. Findings revealed that as much as 24 to 32% of the sample experienced the violations in the United States depending on the estimation method. Findings also provided empirical evidence missing in the literature: Union membership and employment-based health insurance coverage significantly reduce the odds of experiencing violations, while part-time employment increases the odds. An indicator of a fissured employment relationship, however, was found insignificant to experiencing the violations. [ABSTRACT FROM AUTHOR]

In 2018, the Ninth Circuit ruled in Martin v. City of Boise that the city's ordinance criminalizing individuals for sleeping or camping outdoors in public space--an increasingly popular method for cities to regulate the homeless--is unconstitutional under the Eighth Amendment's Cruel and Unusual Punishments Clause. Martin was not the first case in which a court struck down an anti-homeless ordinance under the Eighth Amendment. However, it was the first to deem it unconstitutional for a city to punish a homeless person for sleeping outside when shelters are not "practically available," even if they technically have available beds. The court in Martin said the shelters at issue were not practically available because they were religiously coercive. This Note argues, however, that courts reviewing criminalization measures should consider whether shelters are practically available to homeless individuals for reasons beyond religious coercion. Many functional barriers to shelter deprive homeless individuals of a meaningful choice, and the Eighth Amendment prevents governments from punishing individuals for matters beyond their control. Courts should make individualized inquiries when considering the constitutionality of criminalization measures to assess whether individuals experiencing homelessness truly have a meaningful "choice" in sleeping outside. However, the constitutional infirmities behind criminalization measures, the highly factual inquiries required of courts to determine their constitutionality, and their exacerbation of homelessness underscore the need for cities to stop criminalizing homelessness.

Background: Multisensory approaches and programmes have been developed to improve the quality of both life and dying for people with advanced dementia. However, little is known about the experiences of staff, family and others involved in the use of these programmes, and in the relevant education provided to improve the quality of life of residents living with advanced dementia in long-term care homes. Aim: The aim of this study was to explore early experiences associated with the implementation of a new programme called 'Namaste Care' in two Canadian long-term care homes. Methods: A multiple methods design was used. This included a survey to evaluate a 2-day education programme and qualitative description of interview data that explored experiences during the first 3 months of implementation. Results: Survey respondents included 44 long-term care staff and 44 others (primarily family) who had attended a 2-day training session or public lecture. Interviews were undertaken with 18 staff, 5 family members and 2 volunteers to generate qualitative descriptions about the last 3 months of implementation of the 2-day education programme. The majority of those who attended training rated this as excellent and affirmed that they now understood the purpose of 'Namaste Care'. Most endorsed that they had learned some essentials of 'Namaste Care' delivery. The majority of those who attended the public lecture were very satisfied with the education, and better understood how this novel programme could be implemented in long-term care. Qualitative description of interview data revealed that participants were positive about 'Namaste Care' in long-term care, and identified both barriers and facilitators to implementation as well as recommendations to help with future implementation. Conclusions: These study findings support the use of a facility-wide educational programme to help launch a new innovation in long-term care. [ABSTRACT FROM AUTHOR]

Background: Physicians and therapists are also consulted to give judgments on working ability. Ability to work cannot simply be derived from the patient's symptom status but from the illness-related capacity impairments in relation to the work demands. A structured assessment of capacity impairments has been evaluated and applied internationally: the Mini-ICF-APP Social Functioning Scale. It is currently unclear whether a free-text clinical report (i.e., usual clinical practice: clinical exploration according to clinical standards, but without a standardized documentation form, instead a text is written) and a structured capacity assessment correspond to the overall work ability judgment, i.e., the decision whether a patient is "fit for work" or "unfit for work." Objectives: This investigation assessed, for the first time, whether usual clinical judgment and the additional structured capacity rating support the work ability decision. Methods: A total of 100 medical reports from patients in a psychotherapy hospital were excerpted for psychopathological symptoms and capacity disorders using a checklist. Additionally, a structured assessment of capacity disorders was documented on the Mini-ICF-APP rating for all patients. Results: In the free-text clinical medical report, endurance, flexibility, and contacts to others were the things mainly reported as impaired. This was similar to the structured Mini-ICF-APP rating. However, other capacity impairments were also reported in the Mini-ICF-APP, i.e., adherence to rules and regulations, planning and structuring, assertiveness, and group integration. When the free-text clinical report and the structured Mini-ICF-APP rating were compared, there was a higher rate of stated impairments covering all capacity dimensions in the Mini-ICF-APP rating. Conclusions: The free-text report in the medical report shows the differences between patients who are fit for work and those who are not, and thus speak for the validity of work ability decisions. However, optimization is possible in terms of depth and differentiation of capacity impairment description by adhering to the standard set by the Mini-ICF-APP. [ABSTRACT FROM AUTHOR]

Background: Dysuria following prostate radiation therapy is a common toxicity that adversely affects patients' quality of life and may be difficult to manage. Methods: Two hundred four patients treated with stereotactic body radiation therapy (SBRT) from 2007 to 2010 for localized prostate carcinoma with a minimum follow-up of 3 years were included in this retrospective review of prospectively collected data. All patients were treated to 35-36.25 Gy in five fractions delivered with robotic SBRT with real time fiducial tracking. Dysuria and other lower urinary tract symptoms were assessed via Question 4b (Pain or burning on urination) of the expanded prostate index composite-26 and the American Urological Association (AUA) Symptom Score at baseline and at routine follow-up. results: Two hundred four patients (82 low-, 105 intermediate-, and 17 high-risk according to the D'Amico classification) at a median age of 69 years (range 48-91) received SBRT for their localized prostate cancer with a median follow-up of 47 months. Bother associated with dysuria significantly increased from a baseline of 12% to a maximum of 43% at 1 month (p < 0.0001). There were two distinct peaks of moderate to severe dysuria bother at 1 month and at 6-12 months, with 9% of patients experiencing a late transient dysuria flare. While a low level of dysuria was seen through the first 2 years of follow-up, it returned to below baseline by 2 years (p = 0.91). The median baseline AUA score of 7.5 significantly increased to 11 at 1 month (p < 0.0001) and returned to 7 at 3 months (p = 0.54). Patients with dysuria had a statistically higher AUA score at baseline and at all follow-ups up to 30 months. Dysuria significantly correlated with dose and AUA score on multivariate analysis. Frequency and strain significantly correlated with dysuria on stepwise multivariate analysis. conclusion: The rate and severity of dysuria following SBRT is comparable to patients treated with other radiation modalities.

Background. Stereotactic body radiotherapy (SBRT) has emerged as an effective treatment for localized prostate cancer. However, prostate specific antigen (PSA) kinetics after prostate SBRT have not been well characterized. The purpose of this study was to analyze the trend in PSA decline following robotic SBRT from a prospective cohort of patients. Material and methods. In total 175 patients were treated definitively for localized prostate cancer to a dose of 35-36.25 Gy in 5 fractions using robotic SBRT in the absence of androgen deprivation therapy (ADT). PSA and testosterone were collected at regular intervals following treatment and patients were assessed for biochemical failure and benign PSA bounce. A PSA nadir threshold of 0.5 ng/ml was used as a predictor of long-term disease-free survival. Multivariate logistic regression was used to assess the effect of disease specific covariates on the likelihood of achieving a PSA nadir less than threshold. PSA kinetics were analyzed a multi-component exponential model accounting for benign and malignant sources of PSA. Results and conclusion. At a median follow-up of 3 years, 70% of patients achieved a PSA nadir below 0.5 ng/ml with a median PSA nadir of 0.3 ng/ml at a median time to nadir of 30 months. In our cohort, 36.2% experienced a benign PSA bounce. Absence of PSA bounce, initial PSA, and testosterone at the time of nadir proved to be significant predictors of achieving a PSA nadir below threshold. PSA kinetics after prostate SBRT were well described with a functional volume model with fitted half-lives of 4.4 and 14.8 months for malignant and benign sources of PSA, respectively. Patients treated with prostate SBRT experience an initial period of rapid PSA decline followed by a slow decline which will likely result in lower PSA nadirs after longer follow-up. The long-term disease specific impacts of these results remain to be determined. [ABSTRACT FROM AUTHOR]

Background: Hematuria following prostate radiotherapy is a known toxicity that may adversely affect a patient's quality of life. Given the higher dose of radiation per fraction using stereotactic body radiation therapy (SBRT) there is concern that post-SBRT hematuria would be more common than with alternative radiation therapy approaches. Herein, we describe the incidence and severity of hematuria following stereotactic body radiation therapy (SBRT) for prostate cancer at our institution. Methods: Two hundred and eight consecutive patients with prostate cancer treated with SBRT monotherapy with at least three years of follow-up were included in this retrospective analysis. Treatment was delivered using the CyberKnife® (Accuray) to doses of 35-36.25 Gy in 5 fractions. Toxicities were scored using the CTCAE v.4. Hematuria was counted at the highest grade it occurred in the acute and late setting for each patient. Cystoscopy findings were retrospectively reviewed. Univariate and multivariate analyses were performed. Hematuria-associated bother was assessed via the Expanded Prostate Index Composite (EPIC)-26. Results: The median age was 69 years with a median prostate volume of 39 cc. With a median follow-up of 48 months, 38 patients (18.3%) experienced at least one episode of hematuria. Median time to hematuria was 13.5 months. In the late period, there were three grade 3 events and five grade 2 events. There were no grade 4 or 5 events. The 3-year actuarial incidence of late hematuria ⩾ grade 2 was 2.4%. On univariate analysis, prostate volume (p = 0.022) and history of prior procedure(s) for benign prostatic hypertrophy (BPH) (p = 0.002) were significantly associated with hematuria. On multivariate analysis, history of prior procedure(s) for BPH (p < 0.0001) and α1A antagonist use (p = 0.008) were significantly associated with the development of hematuria. Conclusions: SBRT for prostate cancer was well tolerated with hematuria rates comparable to other radiation modalities. Patients factors associated with BPH, such as larger prostate volume, alpha antagonist usage, and prior history of procedures for BPH are at increased risk for the development of hematuria.

Purpose: Stereotactic body radiation therapy (SBRT) is increasingly utilized as primary treatment for clinically localized prostate cancer. Consensus regarding the appropriate patient-reported outcome (PRO) endpoints for clinical trials evaluating radiation modalities for early stage prostate cancer is lacking. To aid in clinical trial design, this study presents PROs over a 36-month period following SBRT for clinically localized prostate cancer. Methods: Between February 2008 and September 2010, 174 hormone-naïve patients with clinically localized prostate cancer were treated with 35-36.25 Gy SBRT (CyberKnife, Accuray) delivered in 5 fractions. Patients completed the validated Expanded Prostate Cancer Index Composite (EPIC)-26 questionnaire at baseline and all follow-ups. The proportion of patients developing a clinically significant decline in each EPIC domain score was determined. The minimally important difference (MID) was defined as a change of one-half the standard deviation from the baseline. Per Radiation Therapy Oncology Group (RTOG) 0938, we also examined the patients who experienced a decline in EPIC urinary domain summary score of >2 points (unacceptable toxicity defined as ⩾60% of all patients reporting this degree of decline) and EPIC bowel domain summary score of >5 points (unacceptable toxicity defined as >55% of all patients reporting this degree of decline) from baseline to 1 year. Results: A total of 174 patients at a median age of 69 years received SBRT with a minimum follow-up of 36 months. The proportion of patients reporting a clinically significant decline (MID for urinary/bowel are 5.5/4.4) in EPIC urinary/bowel domain scores was 34%/30% at 6 months, 40%/32.2% at 12 months, and 32.8%/21.5% at 36 months. The patients reporting a decrease in the EPIC urinary domain summary score of >2 points was 43.2% (CI: 33.7%, 54.6%) at 6 months, 51.6% (CI: 43.4%, 59.7%) at 12 months, and 41.8% (CI: 33.3%, 50.6%) at 36 months. The patients reporting a decrease in the EPIC bowel domain summary score of >5 points was 29.6% (CI: 21.9%, 39.3%) at 6 months, 29% (CI: 22%, 36.8%) at 12 months, and 22.4% (CI: 15.7%, 30.4%) at 36 months. Conclusion: Following prostate SBRT, clinically significant urinary symptoms are more common than bowel symptoms. Our prostate SBRT treatment protocol meets the RTOG 0938 criteria for moving forward to a Phase III trial comparing it to conventionally fractionated radiation therapy. Notably, between 12 and 36 months, the proportion of patients reporting a significant decrease in both EPIC urinary and bowel domain scores declined, suggesting a late improvement in these symptom domains. Further investigation is needed to elucidate (1) which EPIC domains bear the greatest influence on post-treatment quality of life and (2) at what time point PRO endpoint(s) should be assessed.

Background Proctitis after radiation therapy for prostate cancer remains an ongoing clinical challenge and critical quality of life issue. SBRT could minimize rectal toxicity by reducing the volume of rectum receiving high radiation doses and offers the potential radiobiologic benefits of hypofractionation. This study sought to evaluate the incidence and severity of proctitis following SBRT for prostate cancer. Methods Between February 2008 and July 2011, 269 men with clinically localized prostate cancer were treated definitively with SBRT monotherapy at Georgetown University Hospital. All patients were treated to 35-36.25Gy in 5 fractions delivered with the CyberKnife Radiosurgical System (Accuray). Rectal bleeding was recorded and scored using the CTCAE v.4. Telangiectasias were graded using the Vienna Rectoscopy Score (VRS). Proctitis was assessed via the Bowel domain of the Expanded Prostate Index Composite (EPIC)-26 at baseline and at 1, 3, 6, 9, 12, 18 and 24 months post-SBRT. Results The median age was 69 years with a median prostate volume of 39 cc. The median follow-up was 3.9 years with a minimum follow-up of two years. The 2-year actuarial incidence of late rectal bleeding ≥ grade 2 was 1.5%. Endoscopy revealed VRS Grade 2 rectal telangiectasias in 11% of patients. All proctitis symptoms increased at one month post-SBRT but returned to near-baseline with longer follow-up. The most bothersome symptoms were bowel urgency and frequency. At one month post-SBRT, 11.2% and 8.5% of patients reported a moderate to big problem with bowel urgency and frequency, respectively. The EPIC bowel summary scores declined transiently at 1 month and experienced a second, more protracted decline between 6 months and 18 months before returning to near-baseline at two years post-SBRT. Prior to treatment, 4.1% of men felt their bowel function was a moderate to big problem which increased to 11.5% one month post-SBRT but returned to near-baseline at two years post-SBRT. Conclusions In this single institution cohort, the rate and severity of proctitis observed following SBRT is low. QOL decreased on follow-up; however, our results compare favorably to those reported for patients treated with alternative radiation modalities. Future prospective randomized studies are needed to confirm these observations. [ABSTRACT FROM AUTHOR]

Background: Patients with large prostate volumes have been shown to have higher rates of genitourinary and gastrointestinal toxicities after conventional radiation therapy for prostate cancer. The efficacy and toxicity of stereotactic body radiation therapy (SBRT), which delivers fewer high-dose fractions of radiation treatment, is unknown for large prostate volume prostate cancer patients. We report our early experience using SBRT for localized prostate cancer in patients with large prostate volumes. Methods: 57 patients with prostate volumes ≥50 CM3 prior to treatment with SBRT for localized prostate carcinoma and with a minimum follow up of two years were included in this retrospective review of prospectively collected data. Treatment was delivered using Cyberknife (Accuray) with doses of 35–36.25 Gy in 5 fractions. Biochemical control was assessed using the Phoenix definition. Toxicities were scored using the CTCAE v.4. Quality of life was assessed using the American Urological Association (AUA) Symptom Score and the Expanded Prostate Cancer Index Composite (EPIC)-26. Results: 57 patients (23 low-, 25 intermediate- and 9 high-risk according to the D’Amico classification) at a median age of 69 years (range, 54–83 years) received SBRT with a median follow-up of 2.9 years. The median prostate size was 62.9 CM3 (range 50–138.7 CM3). 33.3% of patients received ADT. The median pre-treatment prostate-specific antigen (PSA) was 6.5 ng/ml and decreased to a median PSA of 0.4 ng/ml by 2 years (p <0.0001). A mean baseline AUA symptom score of 7.5 significantly increased to 13 at 1 month (p = 0.001) and returned to baseline by 3 months (p = 0.21). 23% of patients experienced a late transient urinary symptom flare in the first two years following treatment. Mean baseline EPIC bowel scores of 95.8 decreased to 78.1 at 1 month (p <0.0001), but subsequently improved to 93.5 three months (p = 0.08). The 2-year actuarial incidence rates of GU and GI toxicity ≥ grade 2 were 49.1% and 1.8%, respectively. Two patients (3.5%) experienced grade 3 urinary toxicity, and no patient experienced grade 3 gastrointestinal toxicity. Conclusions: SBRT for clinically localized prostate cancer was well tolerated in men with large prostate volumes. [ABSTRACT FROM AUTHOR]

Purpose Urinary incontinence (UI) following prostate radiotherapy is a rare toxicity that adversely affects a patient's quality of life. This study sought to evaluate the incidence of UI following stereotactic body radiation therapy (SBRT) for prostate cancer. Methods Between February, 2008 and October, 2010, 204 men with clinically localized prostate cancer were treated definitively with SBRT at Georgetown University Hospital. Patients were treated to 35-36.25 Gray (Gy) in 5 fractions delivered with the CyberKnife (Accuray). UI was assessed via the Expanded Prostate Index Composite (EPIC)-26. Results Baseline UI was common with 4.4%, 1.0% and 3.4% of patients reporting leaking > 1 time per day, frequent dribbling and pad usage, respectively. Three year post treatment, 5.7%, 6.4% and 10.8% of patients reported UI based on leaking > 1 time per day, frequent dribbling and pad usage, respectively. Average EPIC UI summary scores showed an acute transient decline at one month post-SBRT then a second a gradual decline over the next three years. The proportion of men feeling that their UI was a moderate to big problem increased from 1% at baseline to 6.4% at three years post-SBRT. Conclusions Prostate SBRT was well tolerated with UI rates comparable to conventionally fractionated radiotherapy and brachytherapy. More than 90% of men who were pad-free prior to treatment remained pad-free three years following treatment. Less than 10% of men felt post-treatment UI was a moderate to big problem at any time point following treatment. Longer term followup is needed to confirm late effects. [ABSTRACT FROM AUTHOR]

Purpose: Stereotactic body radiation therapy (SBRT) is increasingly utilized as primary treatment for clinically localized prostate cancer. While acute post-SBRT urinary symptoms are well recognized, the late genitourinary toxicity of SBRT has not been fully described. Here, we characterize the clinical features of late urinary symptom flare and recommend conservative symptom management approaches that may alleviate the associated bother. Methods: Between February 2008 and August 2011, 216 men with clinically localized prostate cancer were treated definitively with SBRT at Georgetown University Hospital. Treatment was delivered using the CyberKnife with doses of 35-36.25 Gy in five fractions. The prevalence of each of five Common Terminology Criteria for Adverse Events (CTCAE) graded urinary toxicities was assessed at each follow-up visit. Medication usage was documented at each visit. Patient-reported urinary symptoms were assessed using the American UrologicalAssociation (AUA) symptom score and the Expanded Prostate Cancer Index Composite (EPIC)-26 at 1, 3, 6, 9, 12, 18, and 24 months. Late urinary symptom flare was defined as an increase in the AUA symptom score of ⩾5 points above baseline with a degree of severity in the moderate to severe range (AUA symptom score ⩾15). The relationship between the occurrence of flare and pre-treatment characteristics were examined. Results: For all patients, the AUA symptom score spiked transiently at 1 month post-SBRT. Of the 216 patients, 29 (13.4%) experienced a second transient increase in the AUA symptom score that met the criteria for late urinary symptom flare. Among flare patients, the median age was 66 years compared to 70 for those without flare (p=0.007). In patients who experienced flare, CTCAE urinary toxicities including dysuria, frequency/urgency, and retention peaked at 9-18 months, and alpha-antagonist utilization increased at 1 month post-treatment, rose sharply at 12 months post-treatment, and peaked at 18 months (85%) before decreasing at 24 months.The EPIC urinary summary score of flare patients declined transiently at 1 month and experienced a second, more protracted decline between 6 and 18 months before returning to near baseline at 2-year post-SBRT. Statistically and clinically significant increases in patient-reported frequency, weak stream, and dysuria were seen at 12 months post-SBRT. Among flare patients, 42.9% felt that urination was a moderate to big problem at 12 months following SBRT. Conclusion: In this study, we characterize late urinary symptom flare following SBRT. Late urinary symptom flare is a constellation of symptoms including urinary frequency/urgency, weak stream, and dysuria that transiently occurs 6-18 months post-SBRT. Provision of appropriate anticipatory counseling and the maintenance of prophylactic alpha-antagonists may limit the bother associated with this syndrome. [ABSTRACT FROM AUTHOR]

Background Stereotactic body radiation therapy (SBRT) delivers high doses of radiation to the prostate while minimizing radiation to adjacent normal tissues. Large fraction sizes may increase the risk of functional decrements. Treatment-related bother may be more important to a patient than treatment-related dysfunction. This study reports on patient-reported outcomes following SBRT for clinically localized prostate cancer. Methods Between August 2007 and July 2011, 228 consecutive hormone-naïve patients with clinically localized prostate cancer were treated with 35-36.25 Gy SBRT delivered using the CyberKnife Radiosurgical System (Accuray) in 5 fractions. Quality of life was assessed using the American Urological Association Symptom Score (AUA) and the Expanded Prostate Cancer Index Composite (EPIC)-26. Urinary symptom flare was defined as an AUA score 15 or more with an increase of 5 or more points above baseline 6 months after treatment. Results 228 patients (88 low-, 126 intermediate- and 14 high-risk) at a median age of 69 (44-90) years received SBRT with a minimum follow-up of 24 months. EPIC urinary and bowel summary scores declined transiently at 1 month and experienced a second, more protracted decline between 9 months and 18 months before returning to near baseline 2 years post- SBRT. 14.5% of patients experienced late urinary symptom flare following treatment. Patients who experienced urinary symptom flare had poorer bowel quality of life following SBRT. EPIC scores for urinary bother declined transiently, first at 1 month and again at 12 months, before approaching pre-treatment scores by 2 years. Bowel bother showed a similar pattern, but the second decline was smaller and lasted 9 months to 18 months. EPIC sexual summary and bother scores progressively declined over the 2 years following SBRT without recovery. Conclusions In the first 2 years, the impact of SBRT on urination and defecation was minimal. Transient late increases in urinary and bowel dysfunction and bother were observed. However, urinary and bowel function and bother recovered to near baseline by 2 years post-SBRT. Sexual dysfunction and bother steadily increased following treatment without recovery. SBRT for clinically localized prostate cancer was well tolerated with treatment-related dysfunction and bother comparable to conventionally fractionated radiation therapy or brachytherapy.

Background Erectile dysfunction after prostate radiation therapy remains an ongoing challenge and critical quality of life issue. Given the higher dose of radiation per fraction using stereotactic body radiation therapy (SBRT) there is concern that post-SBRT impotency would be higher than conventional radiation therapy approaches. This study sought to evaluate potency preservation and sexual function following SBRT for prostate cancer. Methods Between February 2008 and March 2011, 216 men with clinically localized prostate cancer were treated definitively with SBRT monotherapy at Georgetown University Hospital. Potency was defined as the ability to have an erection firm enough for intercourse with or without sexual aids while sexual activity was defined as the ability to have an erection firm enough for masturbation and foreplay. Patients who received androgen deprivation therapy (ADT) were excluded from this study. Ninety-seven hormone-naïve men were identified as being potent at the initiation of therapy and were included in this review. All patients were treated to 35-36.25Gy in 5 fractions delivered with the CyberKnife Radiosurgical System (Accuray). Prostate specific antigen (PSA) and total testosterone levels were obtained pretreatment, every 3 months for the first year and every 6 months for the subsequent year. Sexual function was assessed with the Sexual Health Inventory for Men (SHIM), the Expanded Prostate Index Composite (EPIC)-26 and Utilization of Sexual Medication/Device questionnaires at baseline and all follow-up visits. Results Ninety-seven men (43 low-, 50 intermediate- and 4 high-risk) at a median age of 68 years (range, 48-82 years) received SBRT. The median pre-treatment PSA was 5.9 ng/ml and the minimum follow-up was 24 months. The median pre-treatment total serum testosterone level was 11.4 nmol/L (range, 4.4-27.9 nmol/L). The median baseline SHIM was 22 and 36% of patients utilized sexual aids prior to treatment. Although potency rates declined following treatment: 100% (baseline); 68% (6 months); 62% (12 months); 57% (18 months) and 54.4% (24 months), 78% of previously potent patients had erections sufficient for sexual activity at 24 months post-treatment. Overall sexual aid utilization increased from 36% at baseline to 49% at 24 months. Average EPIC sexual scores showed a slow decline over the first two years following treatment: 77.6 (baseline); 68.7 (6 months); 63.2 (12 months); 61.9 (18 months); 59.3 (24 months). All sexual functions including orgasm declined with time. Prior to treatment, 13.4% of men felt their sexual function was a moderate to big problem which increased to 26.7% two years post treatment. Post-treatment testosterone levels gradually decreased with a median value at two year follow-up of 10.7 nmol/L. However, the average EPIC hormonal scores did not illustrate a statistically significant difference two years posttreatment. Review of the radiation doses to the penile bulb in this study, a potential marker of post-treatment sexual function, revealed that the dose was relatively low and at these low doses the percentage of the penile bulb receiving 29.5 Gy did not correlate with the development of ED. Conclusions Men undergoing SBRT monotherapy for prostate cancer report sexual outcomes comparable to those reported for conventional radiation modalities within the first 24 months after treatment. Longer follow-up is required to confirm the durability of these findings. [ABSTRACT FROM AUTHOR]

Prostate cancer (PCa) is the most common type of cancer in men in the United States, which disproportionately affects African American descents. While metastasis is the most common cause of death among PCa patients, no specific markers have been assigned to severity and ethnic biasness of the disease. MicroRNAs represent a promising new class of biomarkers owing to their inherent stability and resilience. In the present study, we investigated potential miRNAs that can be used as biomarkers and/or therapeutic targets and can provide insight into the severity and ethnic biasness of PCa. PCR array was performed in FFPE PCa tissues (5 Caucasian American and 5 African American) and selected differentially expressed miRNAs were validated by qRT-PCR, in 40 (15 CA and 25 AA) paired PCa and adjacent normal tissues. Significantly deregulated miRNAs were also analyzed in urine samples to explore their potential as non-invasive biomarker for PCa. Out of 8 miRNAs selected for validation from PCR array data, miR-205 (p<0.0001), mir-214 (p<0.0001), miR-221(p<0.001) and miR-99b (p<0.0001) were significantly downregulated in PCa tissues. ROC curve shows that all four miRNAs successfully discriminated between PCa and adjacent normal tissues. MiR-99b showed significant down regulation (p<0.01) in AA PCa tissues as compared to CA PCa tissues and might be related to the aggressiveness associated with AA population. In urine, miR-205 (p<0.05) and miR-214 (p<0.05) were significantly downregulated in PCa patients and can discriminate PCa patients from healthy individuals with 89% sensitivity and 80% specificity. In conclusion, present study showed that miR-205 and miR-214 are downregulated in PCa and may serve as potential non-invasive molecular biomarker for PCa. [ABSTRACT FROM AUTHOR]

Background: Stereotactic body radiation therapy (SBRT) delivers fewer high-dose fractions of radiation which may be radiobiologically favorable to conventional low-dose fractions commonly used for prostate cancer radiotherapy. We report our early experience using SBRT for localized prostate cancer. Methods: Patients treated with SBRT from June 2008 to May 2010 at Georgetown University Hospital for localized prostate carcinoma, with or without the use of androgen deprivation therapy (ADT), were included in this retrospective review of data that was prospectively collected in an institutional database. Treatment was delivered using the CyberKnife® with doses of 35 Gy or 36.25 Gy in 5 fractions. Biochemical control was assessed using the Phoenix definition. Toxicities were recorded and scored using the CTCAE v.3. Quality of life was assessed before and after treatment using the Short Form-12 Health Survey (SF-12), the American Urological Association Symptom Score (AUA) and Sexual Health Inventory for Men (SHIM) questionnaires. Late urinary symptom flare was defined as an AUA score = 15 with an increase of = 5 points above baseline six months after the completion of SBRT. Results: One hundred patients (37 low-, 55 intermediate- and 8 high-risk according to the D'Amico classification) at a median age of 69 years (range, 48-90 years) received SBRT, with 11 patients receiving ADT. The median pretreatment prostate-specific antigen (PSA) was 6.2 ng/ml (range, 1.9-31.6 ng/ml) and the median follow-up was 2.3 years (range, 1.4-3.5 years). At 2 years, median PSA decreased to 0.49 ng/ml (range, 0.1-1.9 ng/ml). Benign PSA bounce occurred in 31% of patients. There was one biochemical failure in a high-risk patient, yielding a two-year actuarial biochemical relapse free survival of 99%. The 2-year actuarial incidence rates of GI and GU toxicity = grade 2 were 1% and 31%, respectively. A median baseline AUA symptom score of 8 significantly increased to 11 at 1 month (p = 0.001), however returned to baseline at 3 months (p = 0.60). Twenty one percent of patients experienced a late transient urinary symptom flare in the first two years following treatment. Of patients who were sexually potent prior to treatment, 79% maintained potency at 2 years post-treatment. Conclusions: SBRT for clinically localized prostate cancer was well tolerated, with an early biochemical response similar to other radiation therapy treatments. Benign PSA bounces were common. Late GI and GU toxicity rates were comparable to conventionally fractionated radiation therapy and brachytherapy. Late urinary symptom flares were observed but the majority resolved with conservative management. A high percentage of men who were potent prior to treatment remained potent two years following treatment. [ABSTRACT FROM AUTHOR]

Background: Hypofractionated stereotactic body radiation therapy (SBRT) has been advanced as monotherapy for low-risk prostate cancer. We examined the dose distributions and early clinical outcomes using this modality for the treatment of intermediate-risk prostate cancer. Methods: Forty-one sequential hormone-naïve intermediate-risk prostate cancer patients received 35-36.25 Gy of CyberKnife-delivered SBRT in 5 fractions. Radiation dose distributions were analyzed for coverage of potential microscopic ECE by measuring the distance from the prostatic capsule to the 33 Gy isodose line. PSA levels, toxicities, and quality of life (QOL) measures were assessed at baseline and follow-up. Results: All patients completed treatment with a mean coverage by the 33 Gy isodose line extending >5 mm beyond the prostatic capsule in all directions except posteriorly. Clinical responses were documented by a mean PSA decrease from 7.67 ng/mL pretreatment to 0.64 ng/mL at the median follow-up of 21 months. Forty patients remain free from biochemical progression. No Grade 3 or 4 toxicities were observed. Mean EPIC urinary irritation/ obstruction and bowel QOL scores exhibited a transient decline post-treatment with a subsequent return to baseline. No significant change in sexual QOL was observed. Conclusions: In this intermediate-risk patient population, an adequate radiation dose was delivered to areas of expected microscopic ECE in the majority of patients. Although prospective studies are needed to confirm long-term tumor control and toxicity, the short-term PSA response, biochemical relapse-free survival rate, and QOL in this interim analysis are comparable to results reported for prostate brachytherapy or external beam radiotherapy.

A wide array of institutions governing climate change has proliferated over the past years, influencing the rule-makings of the regime. One of them is the G20. When G20 leaders around the world convened in London to restore global economies, they stressed the importance of a 'resilient, sustainable, and green recovery' and reaffirmed their commitments to address climate change. This was followed by their agreement on phasing out inefficient fossil fuel energy subsidies over the medium term in Pittsburgh. The 'coexistence of narrow regimes in the same issue-area' could be described as 'regime complexes', which enable countries to adapt more readily, particularly when adaptation requires complex changes in norms and behavior. Given that responses to climate change would require changes in the domestic politics of different countries at different levels, loosely integrated institutions of regime complexes could be more advantageous for countries to adapt and in engaging with developing countries. This paper demonstrates that the G20's highly informal institutional setup as well as its flexible cooperation tools could enable its members to customize their policies and better engage with third-party countries. In addition, the G20 group could collectively influence other key countries to reach an agreement on some of the key climate change-related issues, thereby facilitating the United Nations process of climate change.

Background: Fatigue is a common side effect of conventional prostate cancer radiation therapy. The increased delivery precision necessitated by the high dose per fraction of stereotactic body radiation therapy (SBRT) offers the potential of reduce target volumes and hence the exposure of normal tissues to high radiation doses. Herein, we examine the level of fatigue associated with SBRT treatment. Methods: Forty patients with localized prostate cancer treated with hypofractionated SBRT, and a minimum of 12 months follow-up were included in this analysis. Self-reported fatigue and other quality of life measures were assessed at baseline and at 1, 3, 6, 9, and 12 months post-SBRT. Results: Mean levels of fatigue were elevated at 1 month post-SBRT compared to baseline values (P = 0.02). Fatigue at the 3-month follow-up and later were higher but not statistically significantly different compared to baseline. African-American patients reported higher fatigue post-SBRT than Caucasian patients. Fatigue was correlated with hormonal symptoms as measured by the Expanded Prostate Cancer Index Composite (EPIC) quality of life questionnaire, but not with urinary, bowel, or sexual symptoms. Age, co-morbidities, smoking, prostate specific antigen (PSA) levels, testosterone levels, tumor stage, and treatment variables were not associated with fatigue. Conclusion: This is the first study to investigate fatigue as a side effect of SBRT. In contrast to standard radiation therapy, results suggest SBRT-related fatigue is short-term rather than a long-term side effect of SBRT. These results also suggest post-SBRT fatigue to be a more frequent complication in African-Americans than Caucasians. [ABSTRACT FROM AUTHOR]

Background: The CyberKnife is an appealing delivery system for hypofractionated stereotactic body radiation therapy (SBRT) because of its ability to deliver highly conformal radiation therapy to moving targets. This conformity is achieved via 100s of non-coplanar radiation beams, which could potentially increase transitory testicular irradiation and result in post-therapy hypogonadism. We report on our early experience with CyberKnife SBRT for low- to intermediate-risk prostate cancer patients and assess the rate of inducing biochemical and clinical hypogonadism. Methods: Twenty-six patients were treated with hypofractionated SBRT to a dose of 36.25 Gy in 5 fractions. All patients had histologically confirmed low- to intermediate-risk prostate adenocarcinoma (clinical stage ≤ T2b, Gleason score ≤ 7, PSA ≤ 20 ng/ml). PSA and total testosterone levels were obtained pre-treatment, 1 month posttreatment and every 3 months thereafter, for 1 year. Biochemical hypogonadism was defined as a total serum testosterone level below 8 nmol/L. Urinary and gastrointestinal toxicity was assessed using Common Toxicity Criteria v3; quality of life was assessed using the American Urological Association Symptom Score, Sexual Health Inventory for Men and Expanded Prostate Cancer Index Composite questionnaires. Results: All 26 patients completed the treatment with a median 15 months (range, 13-19 months) follow-up. Median pre-treatment PSA was 5.75 ng/ml (range, 2.3-10.3 ng/ml), and a decrease to a median of 0.7 ng/ml (range, 0.2-1.8 ng/ml) was observed by one year post-treatment. The median pre-treatment total serum testosterone level was 13.81 nmol/L (range, 5.55 - 39.87 nmol/L). Post-treatment testosterone levels slowly decreased with the median value at one year follow-up of 10.53 nmol/L, significantly lower than the pre-treatment value (p < 0.013). The median absolute fall was 3.28 nmol/L and the median percent fall was 23.75%. There was no increase in biochemical hypogonadism at one year post-treatment. Average EPIC sexual and hormonal scores were not significantly changed by one year post-treatment. [ABSTRACT FROM AUTHOR]

The purposes of this study are (1) to investigate how spacing in the Korean script fields in bibliographic records affects retrieval in various OPAC systems and (2) to propose ways to deal with these problems. We conclude that, from the end-user perspective, the systems using morphological indexing are harder to use than the systems using single character indexing where spaces had no impact on retrieval. We also recommend using both n-gram and morphological indexing, adopting good ranking systems, developing active education programs on this issue, and providing cross references between Chinese and Korean characters.

Surveying 136 exporting firms from ten Organization for Economic Cooperation and Development (OECD) and non-OECD countries, this article documents the incidence, and impact of, non-tariff measures that are perceived to act as barriers to trade in seven sectors of environmental goods and associated services. Although the DDA has a mandate to address, inter alia, such trade barriers, information shedding light on the specific problems that firms encounter in their export activities has been scarce. Accounts by exporting firms in Austria, Brazil, Canada, Chile, France, Germany, India, Japan, Korea and the United States suggest that environmental goods indeed face a variety of obstacles when traded abroad. Firms participating in the survey mentioned relatively often problems associated with product testing and certification requirements, customs procedures, regulations on payment, problems with intellectual property protection, government procurement procedures and technical regulations and standards. Certain types of reported barriers appear to be more prevalent in certain markets. For example, customs procedures reportedly pose a problem predominantly in developing and transition economies and problems with intellectual property rights are associated especially with China. The non-tariff barriers reported by the firms appear to be generic and not specific to the environmental sector. The article shows that in many countries the environmental industry consists mostly of SMEs, for whom cost-raising barriers pose disproportionately greater problems due to their limited resources. The survey helps to better understand the effects that NTBs have at the firm level, and what firms do when they encounter barriers of various types. It appears that the firms participating in this study mostly seek to devise ways of coping with the difficulties that they encounter, rather than seeking help from governments. Since these measures are ad hoc and do not address problems at their source, they cannot substitute for governments taking action. The study points out that many of the concerns voiced by firms in the environment sector can be addressed at the WTO but that more can be done also at the bilateral and regional levels.

The article discusses the two key challenges in the negotiations on environmental goods including the dual and multiple use of environmental products and a review process of product coverage. The intrinsic nature of multiple uses of environmental goods imposes an additional compliance on customs authorities as it requires post-clearance audits. Identifying environmental goods based on their end use at customs would appear to be inevitable if countries wish to screen out products that are not used for environmental purposes. Once established, countries could set an artificial threshold and allow special customs clearance procedures for products that are predominantly used for environmental purposes.
