Secondary Cancer Risk for Stage I Seminoma Patients - a Comparison of Adjuvant Treatment Versus Surveillance

Background: Post-surgical management of stage I seminoma includes: surveillance with repeated CT-scans and treatment reserved for those who relapse, or adjuvant treatment with either immediate radiation therapy (RT) or carboplatin. The cancer specific survival is close to 100%. Cure without long-term sequelae of treatment is the aim. Our goal is to estimate the risk of radiation-induced secondary cancers (SC) death from for patients undergoing S, adjuvant RT or adjuvant carboplatin (AC).Materials and Methods: We measured organ doses from CT scans (3 phases each one) of a seminoma patient who was part of the active surveillance strategy and from a man undergoing adjuvant RT 20-Gy and a 30-Gy salvage RT treatment to the para-aortic area using helical Intensity Modulated RT (Tomotherapy®) with accurate delineation of organs at risk and a CTV to PTV expansion of 1 cm. Effective doses to organs in mSv were estimated according to the tissue-weighting factors recommendations of the International Commission on Radiological Protection 103 (Ann ICRP 2007). We estimated SC incidence and mortality for a 10,000 people population based on the excess absolute risk model from the Biological Effects of Ionizing Radiation (BEIR) VII (Health Risk of Exposure to Low Levels of Ionizing Radiation, NCR, The National Academies Press Washington, DC, 2006) assuming a seminoma diagnosis at age 30, a total life expectancy of 80 years.Results: The nominal risk for a fatal secondary cancers was calculated 1.5% for 15 abdominal CT scans, 14.8% for adjuvant RT (20 Gy paraaortic field) and 22.2% for salvage RT (30 Gy). The calculation assumed that the risk of relapse on surveillance and adjuvant AC was 15% and 4% respectively and that all patients were salvaged at relapse with RT. n CT abdomen/Pelvis = secondary cancer % RT Dose and % receiving treatment = secondary cancer % Total secondary cancer risk in % Active surveillance 15 = 1.5% 30 Gy in 15% of pts = 3.3% 4.8 Adjuvant carboplatin 7 = 0.7% 30 Gy in 4% of pts = 0.88% 1.58 Adjuvant radiotherapy 7 = 0.7% 20 Gy in 100% of pts = 14.8% 15.5Conclusions: These data suggest that: 1) Adjuvant radiotherapy is harmful and should not anymore be regarded as a standard option for seminoma stage I. 2) AC seems to be an option to reduce radiation induced cancers. Limitations: the study does not consider secondary cancers due to chemotherapy with AC (unknown). The use of BEIR VII for risk modeling with higher doses of RT needs to be validated.

Anthropogenic disturbance as a driver of microspatial and microhabitat segregation of cytotypes of Centaurea stoebe and cytotype interactions in secondary contact zones.

BACKGROUND AND AIMS: In a mixed-ploidy population, strong frequency-dependent mating will lead to the elimination of the less common cytotype, unless prezygotic barriers enhance assortative mating. However, such barriers favouring cytotype coexistence have only rarely been explored. Here, an assessment is made of the mechanisms involved in formation of mixed-ploidy populations and coexistence of diploid plants and their closely related allotetraploid derivates from the Centaurea stoebe complex (Asteraceae). METHODS: An investigation was made of microspatial and microhabitat distribution, life-history and fitness traits, flowering phenology, genetic relatedness of cytotypes and intercytotype gene flow (cpDNA and microsatellites) in six mixed-ploidy populations in Central Europe. KEY RESULTS: Diploids and tetraploids were genetically differentiated, thus corroborating the secondary origin of contact zones. The cytotypes were spatially segregated at all sites studied, with tetraploids colonizing preferentially drier and open microhabitats created by human-induced disturbances. Conversely, they were rare in more natural microsites and microsites with denser vegetation despite their superior persistence ability (polycarpic life cycle). The seed set of tetraploid plants was strongly influenced by their frequency in mixed-ploidy populations. Triploid hybrids originated from bidirectional hybridizations were extremely rare and almost completely sterile, indicating a strong postzygotic barrier between cytotypes. CONCLUSIONS: The findings suggest that tetraploids are later immigrants into already established diploid populations and that anthropogenic activities creating open niches favouring propagule introductions were the major factor shaping the non-random distribution and habitat segregation of cytotypes at fine spatial scale. Establishment and spread of tetraploids was further facilitated by their superior persistence through the perennial life cycle. The results highlight the importance of non-adaptive spatio-temporal processes in explaining microhabitat and microspatial segregation of cytotypes.

DMC Section: 2008 State of Iowa Juvenile Justice and Delinquency Prevention Act Formula Grant Update, March 2009

This document is the DMC Section of Iowa’s 2009 federal Juvenile Justice and Delinquency Prevention Act (JJDP Act) formula grant three year plan update. The Division of Criminal and Juvenile Justice Planning (CJJP) wrote this update. CJJP is the state agency responsible for administering the JJDP Act in Iowa. Federal officials refer to state administering agencies as the state planning agency (SPA). The Plan was developed and approved by Iowa’s Juvenile Justice Advisory Council. That Council assists with administration of the JJDP Act, and also provides guidance and direction to the SPA, the Governor and the legislature regarding juvenile justice issues in Iowa. Federal officials refer to such state level groups as state advisory groups (SAG’s). The acronyms SPA and SAG are used through this report.

Juvenile Crime Prevention Community Grand Fund Outcomes Report and FY2002 Juvenile Justice Youth Development Program Summary, January 2002

This document contains two related, but separate reports. The Juvenile Crime Prevention Community Grant Fund Outcomes Report is a summary of outcomes from services and activities funded through the Juvenile Crime Prevention Community Grant Fund in FY2001. The Juvenile Justice Youth Development Program Summary describes Iowa communities’ current prevention and sanction programs supported with funding from the Division of Criminal and Juvenile Justice Planning (CJJP) during FY2002. The material in Juvenile Crime Prevention Community Grant Fund Outcomes Report is presented in response to a legislative mandate to report specific prevention outcomes for the community Grant Fund. It includes a brief description of a Youth Development Results Framework established by the Iowa Collaboration for Youth Development. Outcomes are reported using this results framework, which was developed by a number of state agencies as a common tool for various state programs involving youth development related planning and funding processes. Included in this report is a description of outcomes from the prevention activities funded, all or in part, by the Community Grant Fund, as reported by local communities. The program summaries presented in the Juvenile Justice Youth Development Program Summary provide an overview of local efforts to implement their 2002 Juvenile Justice Youth Development plans and include prevention and sanction programs funded through the combined resources of the State Community Grant Fund and the Federal Title V Prevention, Juvenile Justice & Delinquency Prevention Act Formula Grant and Juvenile Accountability Incentive Block Grant programs. These combined funds are referred to in this document as the Juvenile Justice Youth Development (JJYD) funds. To administer the JJYD funds, including funds from the Community Grant Fund, CJJP partners with local officials to facilitate a community planning process that determines the communities’ priorities for the use of the funds. The local planning is coordinated by the Iowa’s Decategorization Boards (Decats). These local officials and/or their staff have been leaders in providing oversight or staff support to a variety of local planning initiatives (e.g. child welfare, Comprehensive Strategy Pilot Projects, Empowerment, other) and bring child welfare and community planning experience to the table for the creation of comprehensive community longterm planning efforts. The allocation of these combined funds and the technical assistance received by the Decats from CJJP is believed to have helped enhance both child welfare and juvenile justice efforts locally and has provided for the recognition and establishment of connections for joint child welfare/juvenile justice planning. The allocation and local planning approach has allowed funding from CJJP to be “blended” or “braided” with other local, state, and federal dollars that flow to communities as a result of their local planning responsibilities. The program descriptions provided in this document reflect services and activities supported with JJYD funds. In many cases, however, additional funding sources have been used to fully fund the programs. Most of the information in this document’s two reports was submitted to CJJP by the communities through an on- line planning and reporting process established jointly by the DHS and CJJP.

Place de ta vitamine D, du sevelamer et du cinacalcet dans la prise en charge des patients en insuffisance rénale [Treatment of secondary hyperparathyroidism in renal insufficiency: role of calcitriol, sevelamer and cinacalcet]

Along with the decrease in kidney function arises a secondary hyperparathyroidism, which constitutes one of the most important risk factor for mortality in patients suffering from renal insufficiency. Treating secondary hyperparathyroidism is challenging, as most of the parameters of mineral metabolism are interconnected. We review here the pathophysiology and treatment options of this entity.

prophylaxis of experimental endocarditis with antiplatelet and antithrombin agents : a role for long-term prevention of infective endocarditis in humans?

BACKGROUND: Infective endocarditis (IE) mostly occurs after spontaneous low-grade bacteremia. Thus, IE cannot be prevented by circumstantial antibiotic prophylaxis. Platelet activation following bacterial-fibrinogen interaction or thrombin-mediated fibrinogen-fibrin polymerization is a critical step in vegetation formation. We tested the efficacy of antiplatelet and antithrombin to prevent experimental IE. METHODS: A rat model of experimental IE following prolonged low-grade bacteremia mimicking smoldering bacteremia in humans was used. Prophylaxis with antiplatelets (aspirin, ticlopidine [alone or in combination], eptifibatide, or abciximab) or anticoagulants (antithrombin dabigatran etexilate or anti-vitamin K acenocoumarol) was started 2 days before inoculation with Streptococcus gordonii or Staphylococcus aureus. Valve infection was assessed 24 hours later. RESULTS: Aspirin plus ticlopidine, as well as abciximab, protected 45%-88% of animals against S. gordonii and S. aureus IE (P < .05). Dabigatran etexilate protected 75% of rats against IE due to S. aureus (P < .005) but failed to protect against S. gordonii (<30% protection). Acenocoumarol was ineffective. CONCLUSIONS: Antiplatelet and direct antithrombin agents may be useful in the prophylaxis of IE in humans. In particular, the potential dual benefit of dabigatran etexilate might be reconsidered for patients with prosthetic valves, who require life-long anticoagulation and in whom S. aureus IE is associated with high mortality.

Addressing trypsin bias in large scale (phospho)proteome analysis by size exclusion chromatography and secondary digestion of large post-trypsin peptides.

In the vast majority of bottom-up proteomics studies, protein digestion is performed using only mammalian trypsin. Although it is clearly the best enzyme available, the sole use of trypsin rarely leads to complete sequence coverage, even for abundant proteins. It is commonly assumed that this is because many tryptic peptides are either too short or too long to be identified by RPLC-MS/MS. We show through in silico analysis that 20-30% of the total sequence of three proteomes (Schizosaccharomyces pombe, Saccharomyces cerevisiae, and Homo sapiens) is expected to be covered by Large post-Trypsin Peptides (LpTPs) with M(r) above 3000 Da. We then established size exclusion chromatography to fractionate complex yeast tryptic digests into pools of peptides based on size. We found that secondary digestion of LpTPs followed by LC-MS/MS analysis leads to a significant increase in identified proteins and a 32-50% relative increase in average sequence coverage compared to trypsin digestion alone. Application of the developed strategy to analyze the phosphoproteomes of S. pombe and of a human cell line identified a significant fraction of novel phosphosites. Overall our data indicate that specific targeting of LpTPs can complement standard bottom-up workflows to reveal a largely neglected portion of the proteome.

Outcome of subscapularis muscle release for shoulder contracture secondary to brachial plexus palsy at birth.

Children with unresolved brachial plexus palsy frequently develop a disabling internal rotation contracture of the shoulder. Several surgical options, including soft tissue procedures such as muscle releases and/or transfers, and bone operations such as humeral osteotomy are available to correct this deformity. This study describes the effect of subscapularis muscle release performed in isolation. Thirteen patients (5 boys, 8 girls) were reviewed at an average of 3.5 years after their surgery (range, 2-7 years). Their mean age at operation was 4.7 years (range, 1-8 years). Three children had C5-C6 palsies, 8 had C5-C7 palsies, and 2 had C5-C8 palsies. Postoperatively, patients presented significant gains in shoulder active lateral rotation (+49 degrees, from 5 to 54 degrees), active abduction (+30 degrees, from 63 to 93 degrees), active flexion (+46 degrees, from 98 to 144 degrees), and active extension (+23 degrees, from 7 to 30 degrees). Gains were also observed in passive range of motion, but of a lesser degree. Subscapularis muscle release is a procedure we found to have few significant complications and was highly effective in increasing active range of motion and restoring shoulder function.

Determinants of the omega-3 index in a Mediterranean population at increased risk for CHD.

The omega-3 index, defined as the sum of EPA and DHA in erythrocyte membranes expressed as a percentage of total fatty acids, has been proposed as both a risk marker and risk factor for CHD death. A major determinant of the omega-3 index is EPA þ DHA intake, but the impact of other dietary fatty acids has not been investigated. In a cross-sectional study on 198 subjects (102 men and 96 women, mean age 66 years) at high cardiovascular risk living in Spain, the country with low rates of cardiac death despite a high prevalence of cardiovascular risk factors, dietary data were acquired from FFQ and blood cell membrane fatty acid composition was measured by GC. The average consumption of EPA þ DHA was 0·9 g/d and the mean omega-3 index was 7·1%. In multivariate models, EPA þ DHA intake was the main predictor of the omega-3 index but explained only 12% of its variability (P,0·001). No associations with other dietary fatty acids were observed. Although the single most influential determinant of the omega-3 index measured here was the intake of EPA þ DHA, it explained little of the former"s variability; hence, the effects of other factors (genetic, dietary and lifestyle) remain to be determined. Nevertheless, the high omega-3 index could at least partially explain the paradox of low rates of fatal CHD in Spain despite a high background prevalence of cardiovascular risk factors.

A Sufficiency Rating System for Secondary Roads in Iowa, HR-264, Volume I, 1985

County engineers in Iowa face the dual problems of rapidly escalating costs and a decreasing rate of growth of revenues. Various priority systems are in use, ranking projects for inclusion in road improvement programs, but they generally have weaknesses when used to compare one project with another in a different location. The sufficiency rating system has proven to be a useful tool in developing a priority list of projects for primary road systems, but there are none currently in use for secondary road systems. The research reported here was undertaken to develop a sufficiency rating system which could be used for secondary roads in Iowa and to produce the necessary forms and instructions to aid county engineering personnel in their efforts to complete the ratings for roads within their county.

Dépistage et intervention brève par internet pour la consommation d'alcool a risque: www.alcooquizz.ch [Web-based screening and brief intervention for unhealthy alcohol use: www.alcooquizz.ch].

Many individuals with unhealthy alcohol use have few or no contact with the health care system and are therefore unlikely to receive information or a brief intervention from a health care professional. Consequently, many Internet-based interventions have been developed. These interventions can reach a large population. We present in this report www.alcooquizz.ch, a website providing tailored feedback and information on alcohol use and its consequences. In six months and a half, more than 15000 individuals visited the website. It appropriately targets individuals with unhealthy alcohol use and users' satisfaction was high. Internet is a valuable option to provide health related information and secondary prevention interventions for unhealthy alcohol use.

Small RNA-dependent expression of secondary metabolism is controlled by Krebs cycle function in Pseudomonas fluorescens.

Pseudomonas fluorescens CHA0, an antagonist of phytopathogenic fungi in the rhizosphere of crop plants, elaborates and excretes several secondary metabolites with antibiotic properties. Their synthesis depends on three small RNAs (RsmX, RsmY, and RsmZ), whose expression is positively controlled by the GacS-GacA two-component system at high cell population densities. To find regulatory links between primary and secondary metabolism in P. fluorescens and in the related species Pseudomonas aeruginosa, we searched for null mutations that affected central carbon metabolism as well as the expression of rsmY-gfp and rsmZ-gfp reporter constructs but without slowing down the growth rate in rich media. Mutation in the pycAB genes (for pyruvate carboxylase) led to down-regulation of rsmXYZ and secondary metabolism, whereas mutation in fumA (for a fumarase isoenzyme) resulted in up-regulation of the three small RNAs and secondary metabolism in the absence of detectable nutrient limitation. These effects required the GacS sensor kinase but not the accessory sensors RetS and LadS. An analysis of intracellular metabolites in P. fluorescens revealed a strong positive correlation between small RNA expression and the pools of 2-oxoglutarate, succinate, and fumarate. We conclude that Krebs cycle intermediates (already known to control GacA-dependent virulence factors in P. aeruginosa) exert a critical trigger function in secondary metabolism via the expression of GacA-dependent small RNAs.
