Samian deposit (cache) from Papkeszi (Veszprém county, Hungary)
Authors: Gabler Dénes , Mráv Zsolt 
Published: November 2017

A collector handed over to the Hungarian National Museum 15 items of samian ware which he had discovered on the outskirts of Papkeszi. All of the vessels were plain ware: Drag.33 cups or Drag.18/31 platters. 12 pieces bear stamps, with exception one they were all made by the workshops of Lezoux in the Antonine period. Their accordance as a set is evidenced by the graffiti naming Verus on 8 pieces.
The cache of Papkeszi and its closest paralell in space and time the one of Gorsium indicate that they were both purposely hidden deposits. Cache from the same era are also known from Noricum and Pannonia. Deposits from Gorsium and Aquincum can be related to the Marcomannic–Sarmatian attacks of AD 178–179 which among others resulted in the destruction of the earth-timber fort of Celamantia.
Based on samian and brooches the Roman settlement of Papkeszi was inhabited from the Flavian Age. Although its inhabitants might have hidden a cache of terra sigillata as a significant treasure, the Marcomannic–Sarmatian wars (AD 166–180) did not cause any considerable interruption in the occupation of the settlement.

Published: November 2017

We report the results of an effort to measure the contribution of copyright-based industries to the South African economy. Following the methodology of the World Intellectual Property Organization, we identify the copyright industry’s contribution to GDP, employment, imports and exports in South Africa for the period 1970–2009. It was estimated that the sector contributed 4.1% to GDP – more than the contributions of other sectors such as agriculture and food, beverages and tobacco. Because of this quantified importance of the copyright-based industries, we recommend that relevant South African policy authorities and policymakers should monitor and publicise regularly the performance of the copyright-based industries as well as promote programmes for their development and growth.

Significance:

Copyright-based industries have the potential to play an important role in job creation and economic growth.
Our findings suggest that policymakers should design and promote the implementation of future policies and strategies related to these sectors.

Published: November 2017

The early diagnosis of metastatic pulmonary calcification is beneficial, as some patients may develop restrictive changes in respiratory function or in some cases lethal acute respiratory distress. The aim of the study was to evaluate whether scanning with “mTc DPD might be useful in early diagnosis of pulmonary calcification in setting of chronic renal failure and hemodialysis and if presence of pulmonary calcification is associated with an abnormality in respiratory parameters. Forty-two patients with end-stage renal disease, who were treated by regular haemodialysis, were investigated. Twenty five (59.5%) out of forty two patients had increased lung uptake of 99mTc DPD at whole body scintigraphy-grade 2 group. These patients were on dialysis 149±26 months compared with 57±16 months in 17 patients with a normal lung uptake of 99mTc DPD at whole body scintigraphygrade 1 group (p<0.01). In grade 2 group 22 patients (88%) had significantly lower (p<0.01) parameters of spirometry (FEF25-75, FEF75 FEF50, FEF25) compared to predicted values while in grade 1 group the parameters were significantly lower in only six patients (35.3%). There was statistically insignificant difference between these two groups regarding parathyroid hormone level (p>0.05). These observations confirm previous findings that scintigraphy with 99mTc DPD may be efficious in early diagnosis of pulmonary calcification in hemodialised patients as well as the fact that spirometry is useful in patients with confirmed pulmonary calcifications.

Objectives. To estimate changes in the prevalence of daily cannabis use among current, former, and never cigarette smokers from 2002 to 2014 in the United States. Methods. The National Survey on Drug Use and Health is a nationally representative cross-sectional study conducted annually among persons aged 12 years and older in the United States. Results. Daily cannabis use occurs nearly exclusively among nondaily and daily cigarette smokers compared with former and never smokers (8.03%, 9.01%, 2.79%, 1.05%, respectively). Daily cannabis use increased over the past decade among both nondaily (8.03% [2014] vs 2.85% [2002]; linear trend P < .001) and daily smokers (9.01% [2014]; 4.92% [2002]; linear trend P < .001). Daily cannabis use increased most rapidly among former cigarette smokers (2.79% [2014] vs 0.98% [2002]; linear trend P < .001). Conclusions. Daily cannabis use occurs predominantly among cigarette smokers in the United States. Daily cannabis use increased among current, former, and never smokers over the past decade, with particularly rapid increases among youth and female cigarette smokers. Future research is needed to monitor the observed increase in daily cannabis use, especially among youths and adults who smoke cigarettes.
Meeting the Institute of Medicine's 2030 US Life Expectancy Target
Authors: Kindig David , Nobles Jenna , Zidan Moheb 
Published: November 2017

Objectives. To quantify the improvement in US life expectancy required to reach parity with high-resource nations by 2030, to document historical precedent of this rate, and to discuss the plausibility of achieving this rate in the United States. Methods. We performed a demographic analysis of secondary data in 5-year periods from 1985 to 2015. Results. To achieve the United Nations projected mortality estimates for Western Europe in 2030, the US life expectancy must grow at 0.32% a year between 2016 and 2030. This rate has precedent, even in low-mortality populations. Over 204 country-periods examined, nearly half exhibited life-expectancy growth greater than 0.32%. Of the 51 US states observed, 8.2% of state-periods demonstrated life-expectancy growth that exceeded the 0.32% target. Conclusions. Achieving necessary growth in life expectancy over the next 15 years despite historical precedent will be challenging. Much all-cause mortality is structured decades earlier and, at present, older-age mortality reductions in the United States are decelerating. Addressing mortality decline at all ages will require enhanced political will and a strong commitment to equity improvement in the US population.
American Doctors at the Nuremberg Medical Trial
Authors: Shuster Evelyne 
Published: November 2017

Three Hippocratic physicians played critical roles in the prosecution of 23 Nazi doctors charged with murder and torture for conducting lethal medical experiments on concentration camp prisoners. Two of the physicians, Leopold Alexander and Andrew C. Ivy, were Americans, and the other, Werner Leibbrandt, was German.At the 70th anniversary of the Doctors’ Trial it is fitting to recall the three’s influences and contributions to the formulation of strict research ethics rules, known as the Nuremberg Code.Their contributions help us better understand why they insisted on strict research rules and yet ultimately were unable to apply these rules to their own research. Exploring their contributions at Nuremberg may help us appreciate the continuing difficulty physician–researchers have with accepting public regulation of research.

Published: November 2017

Objectives. To measure the risk of concussion among New Mexico middle and high school students during both sports and physical education. Methods. Athletic directors or athletic trainers in 147 schools were asked to report the number of concussions occurring during sports and physical education in the 2013 to 2014 school year. We calculated 1-year cumulative incidence rates. Results. Of the 147 schools, 99 responded (67%). During the school year, 598 students were removed from athletics because of a concussion, a 1-year cumulative incidence of 3.5 per 100. The concussion rate during sports was 3.0: 3.5 for boys and 2.4 for girls (relative risk [RR] = 1.5; 95% confidence interval [CI] = 1.2, 1.7). An additional 335 students experienced concussions during physical education. Concussion rates during physical education were 60% higher than during sports (RR = 1.6; 95% CI = 1.4, 1.8). Conclusions. In our data, the risk of concussion was higher in physical education than in sports. This suggests that concussions should be tracked for a wide range of youth athletic activities, not just for sports. Monitoring cumulative incidence, in addition to other measures, may allow comparisons across schools and regions. More prevention efforts are needed.
Declines in Anogenital Warts Among Age Groups Most Likely to Be Impacted by Human Papillomavirus Vaccination, United States, 2006–2014
Authors: Flagg Elaine W. , Torrone Elizabeth A. 
Published: November 2017

Objectives. To detect decreases in anogenital warts (AGW) among sex and age groups likely to be affected by human papillomavirus vaccination. Methods. We estimated annual AGW prevalence during 2006 to 2014 using health care claims among US private health insurance enrollees aged 15 to 39 years. We derived AGW diagnoses using 1 of the following: (1) condylomata acuminata diagnosis, (2) viral wart diagnosis combined with a benign anogenital neoplasm diagnosis or destruction or excision of an anogenital lesion, or (3) AGW medication combined with a benign anogenital neoplasm diagnosis or destruction or excision of an anogenital lesion. Results. Prevalence decreased during 2008 to 2014 among females aged 15 to 19 years (annual percentage change [APC] = −14.1%; P < .001) and during 2009 to 2014 among women aged 20 to 24 years (APC = −12.9%; P < .001) and among women aged 25 to 29 years (APC = −6.0%; P = .001). We observed significant declines among men aged 20 to 24 years (APC = −6.5%; P = .005). Prevalence increased or was stable in all other sex and age groups. Conclusions. We observed AGW decreases among females in the age groups most likely to be affected by human papillomavirus vaccination and decreases in men aged 20 to 24 years. Decreased prevalence in young men is likely attributable to herd protection from vaccination among females.
Delayed Bone Infarct in the Ilium Following a Pelvic Crush Injury and Embolization
Authors: Millhouse Paul W. , Miller Andrew J. , Paul Jonathan , Conliffe Theodore D. , Vaccaro Alexander R. , Broyer Zach 
Published: November 2017

Case:
We present a case of delayed osteonecrosis of the ilium. After receiving embolization and multiple orthopaedic procedures following a complex pelvic crush injury, the patient subsequently developed posterior pelvic pain and tenderness over the posterior superior iliac spine, along with pain on sacroiliac joint compression. Magnetic resonance imaging of the pelvis demonstrated a bone infarction in the left ilium adjacent to the sacroiliac joint.

Conclusion:
The symptoms from osteonecrosis of the ilium may simulate sacroiliitis or other conditions. It is important to keep the differential diagnosis in mind when considering additional management for posterior pelvic pain in the setting of prior trauma and preexisting hardware.
A Collision Tumor Involving a Primary Leiomyosarcoma of the Lower Extremity and a Metastatic Medullary Thyroid Carcinoma
Authors: Austin Daniel C. , Wu Jim S. , Spentzos Dimitrios , Goldsmith Jeffrey D. , Anderson Megan E. 
Published: November 2017

Case:
A 49-year-old man presented with a rapidly growing thigh mass. Histologic analyses demonstrated separate regions that were consistent with a collision tumor composed of a primary leiomyosarcoma and a metastatic medullary thyroid carcinoma. After responding to chemotherapy, the patient underwent resection of the tumor and a total thyroidectomy; he was disease-free 9 years after the diagnosis.

Conclusion:
A wide diagnostic differential and thorough histologic analysis are necessary in patients presenting with neoplasms of the extremities. A leiomyosarcoma may be a hospitable location for metastatic disease, and the presence of a collision tumor should be considered when pathology findings are equivocal.
Influence of particle properties on iron flocculation
Authors: de Ridder D. J. , van Halem D. 
Published: November 2017

Abstract
In this study, the importance of charge interactions during flocculation of Fe3+ in the presence of particles and anions/cations at various pH values was investigated. SiO2, (s) and ZnO(s) were dosed as particles to promote charge interactions and/or serve as a nucleus to accelerate floc formation. In the pH range 6–9, SiO2, (s) is negatively charged, while ZnO(s) carries a positive charge. Ca2+ and HPO42− were selected to investigate charge interactions in the water phase. A significant delay in floc growth due to charge repulsion between negatively charged iron species was observed at pHini 9. For positively charged species at pHini 6, a delay in floc growth was observed as well, but to a lesser degree. These effects could be neutralized by either dosing (positively charged) ZnO(s) or Ca2+ at pHini 9, or (negatively charged) SiO2, (s) at pHini 6. The addition of phosphate did not hinder floc growth at pHini 6. While phosphate completely inhibited floc growth at pHini 7–9 in the presence of negatively charged SiO2, (s), the presence of positively charged ZnO(s) partly neutralized the detrimental influence of phosphate on floc growth. Similarly, dosing Ca2+ partly neutralized the effect of phosphate.
Anaerobic co-digestion of sludge and microalgae grown in municipal wastewater – a feasibility study
Authors: Olsson J. , Forkman T. , Gentili F. G. , Zambrano J. , Schwede S. , Thorin E. , Nehrenheim E. 
Published: November 2017

Abstract
In this study a natural mix of microalgae grown in wastewater of municipal character was co-digested with sewage sludge in mesophilic conditions, in both batch and semi-continuous modes. The semi-continuous experiment was divided into two periods with OLR1 (organic loading rate) of 2.4 kg volatile solids (VS) m−3 d−1 and HRT1 (hydraulic retention time) of 15 days, and OLR2 of 3.5 kg VS m−3 d−1 and HRT2 of 10 days, respectively. Results showed stable conditions during both periods. The methane yield was reduced when adding microalgae (from 200 ± 25 NmL CH4 g VSin−1, to 168 ± 22 NmL CH4 g VSin−1) but VS reduction was also decreased by 51%. This low digestibility was confirmed in the anaerobic batch test. However, adding microalgae improved the dewaterability of the digested sludge. The high heavy metals content in the microalgae resulted in a high heavy metals content in the digestate, making it more difficult to reuse the digestate as fertilizer on arable land. The heavy metals are thought to originate from the flue gas used as a CO2 source during the microalgae cultivation. Therefore the implementation of CO2 mitigation via algal cultivation requires careful consideration regarding the source of the CO2-rich gas.

Little has been published on the use of artificial diets for the production of butterflies in the Nymphalidae family. We evaluated the effect of a commercial vitamin supplement called Farvital - 18, composed of amino acids, vitamins and electrolytes, on the production of the butterfly Morpho helenor. This supplement was applied on three host plants from the family Fabaceae: Lonchocarpus oliganthus, Erythrina berteroana and Arachis pintoi. We analyzed the duration of the larval stages, the growth rate of the caterpillars at each stage, the survival rate of the caterpillars, pupal weight, and quality and quantity of pupae obtained. Lonchocarpus oliganthus without and with the addition of vitamin supplement produced larger caterpillars, higher survival rate, shorter larval stage duration, and produced heavier and better quality pupae. Arachis pintoi with and without vitamin supplement produced pupae of lower weight. Males fed on Lonchocarpus oliganthus hatched faster but for females the food did not make any difference. Independent of the diet used for the 600 initial larvae, 371 pupae were produced (61,83%). Of the total pupae obtained, 3,63% did not emerge and 88% of the pupae were A quality. The greatest adult emergence occurred between days 14 and 15 of the pupa formation. The pupae of females were heavier than males. The native plant Lonchocarpus oliganthus gave better yields in the production of butterflies Morpho helenor.
CSR Disclosure and Investor Behavior: A Proposed Framework and Research Agenda
Authors: Gödker Katrin , Mertins Lasse 
Published: November 2017

ABSTRACT
How market participants respond to corporate disclosure forms an important cornerstone in many areas of accounting and finance research. This article synthesizes behavioral research on how an increasingly important type of corporate disclosure, namely corporate social responsibility (CSR) disclosure, affects investor behavior. Structuring the extant accounting and finance literature, we derive a holistic framework that consolidates observed drivers of investors' information processing and resulting investment decision making when confronted with CSR disclosure. We identify both disclosure and individual investor characteristics that determine investor behavioral response to disclosed CSR-related information. Drawing on the proposed framework, we pinpoint knowledge gaps in the literature and provide guidelines for further research. Fundamental issues for future work include the decoupling of specific behavioral drivers through innovative measurement, the reliable identification of causal effects, and the incorporation of investors' social interactions.
One Size Fits All? Costs and Benefits of Uniform Accounting Standards
Authors: Ray Korok 
Published: November 2017

ABSTRACT
I build a model of neoclassical production to examine the capital market and welfare effects of a uniform accounting standard (like IFRS). Firms vary in their cost of compliance to the standard, and investors vary in their cost of learning diverse standards for capital allocation. A uniform accounting standard increases the quantity of capital in the economy and lowers the cost of capital. However, uniform standards force diverse firms onto the same standard, which reduces welfare. A regulator selects the optimal number and type of standards to balance these competing effects. Uniform accounting standards are better than diverse accounting standards when firm productivity and variation between investors is large, but worse when the cost of investment and variation between firms is large. I draw implications for IFRS/GAAP convergence and the incentives versus standards debate.
Incretin-Based Therapies and the Short-term Risk of Pancreatic Cancer: Results From Two Retrospective Cohort Studies

Published: November 2017

OBJECTIVE
Concerns have been raised about a possible increased risk of pancreatic cancer associated with incretin-based therapies. We examined the risk of pancreatic cancer among patients with diabetes prescribed incretin drugs.

RESEARCH DESIGN AND METHODS
With the use of public health insurance databases of Belgium and the Lombardy Region, Italy, we created two retrospective cohorts that included adult patients who were first prescribed an incretin drug or another noninsulin antidiabetic drug (NIAD) from 1 July 2008 to 31 December 2013 in Belgium and from 1 January 2008 to 31 December 2012 in the Lombardy Region. The risk of pancreatic cancer was evaluated by multivariate-adjusted Cox models that included time-dependent variables. Adjusted hazard ratios (aHRs) from Belgium and Italy were pooled by using fixed-effects meta-analyses.

RESULTS
The cohorts included 525,733 patients with diabetes treated with NIADs and 33,292 with incretin drugs. Results in both cohorts were similar. Eighty-five and 1,589 subjects who developed pancreatic cancer were registered among the incretin and NIAD new users, respectively, which represented an aHR of pancreatic cancer of 2.14 (95% CI 1.71–2.67) among those prescribed an incretin compared with an NIAD. The aHR with a drug use lag exposure of 6 months was 1.69 (1.24–2.32). The aHR decreased from 3.35 (2.32–4.84) in the first 3 months after the first incretin prescription to 2.12 (1.22–3.66) in months 3–5.9, 1.95 (1.20–3.16) in months 6–11.9, and 1.69 (1.12–2.55) after 12 months. Among those prescribed an NIAD, pancreatic cancer occurred mostly within the year after the first prescription. The risk of pancreatic cancer among patients subsequently prescribed insulin was 6.89 (6.05–7.85).

CONCLUSIONS
The recent prescription of incretin therapy is associated with an increased risk of pancreatic cancer. The reason for such an increase is likely the consequence of an occult pancreatic cancer that provokes or aggravates diabetes. Studies are warranted for assessing the risk of pancreatic cancer associated with long-term use of incretin drugs.
Diet Behavior Change Techniques in Type 2 Diabetes: A Systematic Review and Meta-analysis
Authors: Cradock Kevin A. , ÓLaighin Gearóid , Finucane Francis M. , McKay Rhyann , Quinlan Leo R. , Martin Ginis Kathleen A. , Gainforth Heather L. 
Published: November 2017

OBJECTIVE
Dietary behavior is closely connected to type 2 diabetes. The purpose of this meta-analysis was to identify behavior change techniques (BCTs) and specific components of dietary interventions for patients with type 2 diabetes associated with changes in HbA1c and body weight.

RESEARCH DESIGN AND METHODS
The Cochrane Library, CINAHL, Embase, PubMed, PsycINFO, and Scopus databases were searched. Reports of randomized controlled trials published during 1975–2017 that focused on changing dietary behavior were selected, and methodological rigor, use of BCTs, and fidelity and intervention features were evaluated.

RESULTS
In total, 54 studies were included, with 42 different BCTs applied and an average of 7 BCTs used per study. Four BCTs—“problem solving,” “feedback on behavior,” “adding objects to the environment,” and “social comparison”—and the intervention feature “use of theory” were associated with &gt;0.3% (3.3 mmol/mol) reduction in HbA1c. Meta-analysis revealed that studies that aimed to control or change the environment showed a greater reduction in HbA1c of 0.5% (5.5 mmol/mol) (95% CI −0.65, −0.34), compared with 0.32% (3.5 mmol/mol) (95% CI −0.40, −0.23) for studies that aimed to change behavior. Limitations of our study were the heterogeneity of dietary interventions and poor quality of reporting of BCTs.

CONCLUSIONS
This study provides evidence that changing the dietary environment may have more of an effect on HbA1c in adults with type 2 diabetes than changing dietary behavior. Diet interventions achieved clinically significant reductions in HbA1c, although initial reductions in body weight diminished over time. If appropriate BCTs and theory are applied, dietary interventions may result in better glucose control.
