Spectral Variability of a Soft-intermediate State QPO from MAXI J1820+070
Authors: Davis M. C. , Stevens A. L.
Published: June 2020

Black Hole X-ray binaries are known to exhibit variability in their light curves on timescales as short as milliseconds and as long as months. The short-timescale variability can be in the form of quasi-periodic oscillations (QPOs), which may be produced by general relativistic effects. In this work, we looked at low-frequency QPOs from an exciting recent black hole transient, MAXI J1820+070, which first went into outburst in 2018. This source was observed in a multi-wavelength campaign that included the NICER mission, a soft X-ray telescope attached to the International Space Station. In our analysis, we applied X-ray timing and spectral-timing techniques to help place constraints on the QPO emission mechanism in the extreme environment surrounding the black hole. Although the QPO amplitude was too low to carry out phase-resolved spectroscopy, our work indicates that weak QPOs such as this one may be present in the light curves of many sources.
Fiocruz Biological Collections: strengthening Brazil's biodiversity knowledge and scientific applications opportunities
Authors: da Silva Manuela , Chame Marcia , Moratelli Ricardo
Published: June 2020

Biological collections are central in understanding and preserving life on Earth. In Brazil, the most representative collections are kept by natural history museums, whose primary focus is in invertebrates, vertebrates and vascular plants. Only a few institutions keep repositories in different kingdoms. The Oswaldo Cruz Foundation (Fiocruz), established in 1900, is a strategic public health institution of the Ministry of Health of Brazil. As such, Fiocruz is responsible for a wide range of activities, from basic research to the development and production of vaccines, drugs, reagents and diagnostic kits. Its biological collections were soon established in the expeditions made by naturalists and physicians seeking integrated knowledge of the fauna, flora and tropical diseases. Since then, they have been part of the institutional policy. In a few decades, those collections were already in the forefront of basic and applied research on tropical parasitic and infectious diseases. Currently, they comprise thirty-three repositories representing part of the Brazilian diversity of bacteria, fungi, protozoa, helminths, arthropods, molluscs and plants of medical and environmental importance. Different methods of long-term preservation are applied for the conservation of this wide range of organisms represented by about 6 million specimens. Herein, we describe this range of collections and discuss their complementary role as repositories of groups not represented in other biological collections in Brazil. These valuable biological materials have been used in public health and medical research, as well as for technological development and innovation in Brazil. Parallel to this specific usage, Fiocruz biological collections have played and continue to play a unique and important role in understanding and conserving part of Brazil’s biodiversity that is currently under-represented in other biological and natural history collections in Brazil and South America.
11. Le marché de l’électricité : entre politiques énergétiques nationales et encadrement européen
Authors: Reverdy Thomas , Marty Frédéric
Published: June 2020

La libéralisation du secteur de l’électricité n’a pas signifié la disparition des interventions publiques. Le marché, construit par les directives européennes, coexiste donc avec des interventions publiques visant à porter des objectifs d’intérêt général, pouvant tenir à la promotion des énergies renouvelables, à la sécurité d’approvisionnement ou encore au maintien de tarifs réglementés. Pour autant, ces interventions demeurent sous le contrôle des règles de concurrence européenne, notamment l’encadrement des aides publiques.
14. La crise de l’hôpital en France : le naufrage d’une régulation au point flottant
Authors: Dormont Brigitte
Published: June 2020

La tarification à l’activité (T2A) visait à encourager l’efficience des hôpitaux grâce à un paiement des séjours par forfaits. Le mécanisme économique au cœur de cette réforme a cependant été dénaturé par ses modalités d’application. Alors que les forfaits devaient être fondés sur un mécanisme de concurrence par comparaison, un dispositif de point flottant a été introduit, qui a permis une rigueur budgétaire sans précédent, tout en créant une incitation puissante à réaliser plus de séjours et des actes plus intenses.

Professional Relevance of the Learning Curve: Developing an “A” Team
Authors: Jones-Schenk Jan
Published: June 2020

The term “learning curve” is common professional vernacular for describing a period of profound and intensive learning. Learning can actually be impeded when the curve is consistently on a steep vertical incline. Viewing the learning curve as an “S” instead of a steep bar offers a professional development perspective, as well as a team development perspective, that supports progression and helps to balance team strength.

New Graduate Nurses' Perceptions of Patient Safety: Describing and Comparing Responses With Experienced Nurses
Authors: Forbes Thompson H. , Scott Elaine S. , Swanson Melvin
Published: June 2020

Background:

A significant proportion of the acute health system workforce is composed of new graduate nurses, yet there is a limited understanding of patient safety perceptions among new graduate nurses and how they compare with nurses who have more experience.

Method:

This study used a descriptive approach to complete secondary analysis on two sources of data containing new graduate nurses' (
n
= 1,613) and experienced nurses' (
n
= 64,906) responses to the Hospital Survey on Patient Safety Culture.

Results:

New graduate nurses had a more positive perception of safety culture than more experienced nurses. The greatest differences were observed in perceptions of how nurse managers respond to mistakes. Similarities in perceptions were observed on items associated with communication.

Conclusion:

Educational systems and transitional programs must prepare new graduate nurses for patient care. There is an opportunity for academic and practice partners to collaborate on programs that facilitate the transition of new graduate nurses to the workforce.

Timing and Reoperation Rate of Rhegmatogenous Retinal Detachments Occurring During Major Ophthalmology Meetings
Authors: Vail Daniel , Al-Moujahed Ahmad , Callaway Natalia F. , Ji Marco H. , Ludwig Cassie A. , Moshfeghi Darius M.
Published: June 2020

BACKGROUND AND OBJECTIVE:

To investigate whether surgical management of newly diagnosed rhegmatogenous retinal detachment (RRD) varies if patients are diagnosed during a major national ophthalmology conference.

PATIENTS AND METHODS:

This retrospective cohort study included 34,759 patients with incident RRD, of whom, 1,246 (3.6%) were diagnosed during dates of three national ophthalmology conferences, and 1,170 (3.4%) underwent surgery during conference dates. The authors identified patients with primary repair with cryotherapy, laser, scleral buckle, pneumatic retinopexy, or pars plana vitrectomy. Multinomial logistic regression models were used to determine patients' likelihood of receiving each type of repair within 30 days of their diagnosis depending on whether they were diagnosed during a national ophthalmology conference. Linear regression models were used to determine the relationship between the date patients were diagnosed and how long they waited to receive a repair. Main outcome measures included days between diagnosis with RRD and RRD repair, receiving repair on the same day of diagnosis, and reoperation rate within 30 days of the primary repair.

RESULTS:

Mean time from diagnosis to repair was 1.5 days (standard deviation: ± 2.4 days), and 71% of patients underwent repair within a day of diagnosis. Repairs were followed by a second surgery within 30 days in 11.1% of patients. Patients diagnosed during conferences waited 0.23 days longer between diagnosis and repair compared with patients diagnosed outside of conference dates (
P
= .001). Patients diagnosed with RRD during conferences were less likely to receive surgical repair within a day of diagnosis compared to patients diagnosed during non-conference dates (
P
= .037). Patients who were diagnosed with RRD during a conference date and also received surgery during a conference date were more likely to undergo a second surgery within 30 days of the primary procedure (
P
= .006)

CONCLUSIONS:

Patients diagnosed with RRD during national ophthalmology conference dates waited slightly longer for surgery, were slightly less likely to receive surgery within a day, and were more likely to undergo a second surgery within 30 days of the primary procedure. The “national meeting effect” phenomenon is present in ophthalmology, albeit to a lesser degree that is likely not visually significant.

Retinal Artery Macroaneurysm Associated With Retinal Hemangioblastoma
Authors: Elson Nora C. , Rodriguez Ferdinand , Di Nicola Maura , Williams Basil K.
Published: June 2020

A 34-year-old Caucasian woman with a past medical history of hypertension presented with acute floaters in the right eye (OD) for 1 week. Best-corrected visual acuity (VA) was 20/20 in both eyes.

Fundus examination OD (Figure
1
) revealed a retinal hemangioblastoma (RH) in the temporal midperiphery with a prominent feeding artery and draining vein. A retinal arterial microaneurysm (RAM) was noted within the feeding artery, and subretinal hemorrhage with a cuff of fluid was present. Fundus autofluorescence (Figure
2
) showed hypoautofluorescence in the area of the RH, RAM, and subretinal hemorrhage. A hyperautofluorescent ring surrounding the hemorrhage suggested shallow subretinal fluid. Early phase fluorescein angiography (Figure
3
) demonstrated appropriate arterial and venous filling and hyperfluorescence of the RH.

The RAM appeared hyperfluorescent, whereas the subretinal hemorrhage blocked. There was no evidence of leakage on late images. Optical coherence tomography (OCT) (Figure
4
) through the RAM revealed an inner retinal structure with a central lumen and hyperreflective border. Mild outer retinal exudation was also noted. Fovea was normal on OCT. Fundus examination of the left eye was normal.

Genetic work-up was negative for von Hippel-Lindau disease. Treatment of the hemangioblastoma was offered, but the patient preferred observation. VA remained stable, and better systemic hypertension control was recommended.

Generating geometric body shapes with electromagnetic source scattering techniques
Authors: He Youzi , Li Bin , Sheng Tingting , Wang Xianchao
Published: June 2020

In this paper, we are concerned with the three-dimensional (3D) geometric body shape generation with several well-selected characteristic values. Since 3D human shapes can be viewed as the support of the electromagnetic sources, we formulate a scheme to regenerate 3D human shapes by inverse scattering theory. With the help of vector spherical harmonics expansion of the magnetic far field pattern, we build on a smart one-to-one correspondence between the geometric body space and the multi-dimensional vector space that consists of all coefficients of the spherical vector wave function expansion of the magnetic far field pattern. Therefore, these coefficients can serve as the shape generator. For a collection of geometric body shapes, we obtain the inputs (characteristic values of the body shapes) and the outputs (the coefficients of the spherical vector wave function expansion of the corresponding magnetic far field patterns). Then, for any unknown body shape with the given characteristic set, we use the multivariate Lagrange interpolation to get the shape generator of this new shape. Finally, we get the reconstruction of this unknown shape by using the multiple-frequency Fourier method. Numerical examples of both whole body shapes and human head shapes verify the effectiveness of the proposed method.

Authors: Arul Murugan C.  , Banuselvasaraswathy B.
Published: June 2020

Internet of things (IoT) is a recent technology, and it will become the next generation of internet that connects several physical objects to interact amongst themselves without the assistance of human beings. It plays a significant role in our day-to-day lives and is used in several applications. IoT is a boon to this modern world, but it lacks in security. It cannot protect the user data from assailants, hackers, and vulnerabilities. Field programmable gate arrays (FPGA) helps to achieve all these objectives by incorporating secured end-to-end layer into its architecture. In this chapter, ultralow power and reduced area AES architecture with energy efficient DSE-S box techniques and clock gating for IoT applications are introduced. The proposed AES architecture is implemented over different FPGA families such as Cyclone I, Cyclone II, Virtex 5, and Kintex 7, respectively. From the experimental results, it is observed that the Kintex 7 FPGA kit consumes less power than other FPGA families.
FPGA on Cyber-Physical Systems for the Implementation of Internet of Things
Authors: Nair Rajit , Nair Preeti , Dwivedi Vidya Kant
Published: June 2020

Today, in cyber-physical systems, there is a transformation in which processing has been done on distributed mode rather than performing on centralized manner. Usually this type of approach is known as Edge computing, which demands hardware time to time when requirements in computing performance get increased. Considering this situation, we must remain energy efficient and adaptable. So, to meet the above requirements, SRAM-based FPGAs and their inherent run-time reconfigurability are integrated with smart power management strategies. Sometimes this approach fails in the case of user accessibility and easy development. This chapter presents an integrated framework to develop FPGA-based high-performance embedded systems for Edge computing in cyber-physical systems. The processing architecture will be based on hardware that helps us to manage reconfigurable systems from high level systems without any human intervention.
Neuroscience in FPGA and Application in IoT
Authors: Daisy Anjali
Published: June 2020

Neuroscience is a multidisciplinary science that is focused with the study of the structure and function of the nervous system. It contains the evolution, development, cellular and molecular biology, physiology, anatomy, and pharmacology of the nervous system, as well as computational, interactive, and cognitive neuroscience. A field-programmable gate array (FPGA) is an integrated circuit (IC) that can be programmed in the field after production. FPGAs are likely in principle to have vastly wider potential application than programmable read-only memory (PROM) chips. Internet of things (IoT) is an integrated part of future internet including existing and evolving internet and network developments and could be conceptually defined as a worldwide dynamic network infrastructure with self-configuring capabilities based on standard and interoperable protocols communication where physical and virtual “things” have identities, physical attributes, and virtual personalities.

All We Need is a Boost! Using Multimodal Tools and the Translanguaging Strategy
Authors: Torres María Catalina Caro , Salamanca Yuri Natali Sarmiento , Cely Jennyfer Paola Camargo , Aguilar Jose Leonardo Bautista
Published: June 2020

This article reports a qualitative case study about the implementation of a translanguaging strategy with EFL learners belonging to the Language Learning Support programs at a private university, who struggled when speaking in English. In order to address this problem, this strategy aim to help participants to reflect and self-direct their oral performance development. Multimodal tools were used for learners to undertake a specific course of action to cope with their speaking difficulties. Data gathered from tutor's journals, student's e-portfolio and interviews, showed how confidence and self-regulation were fostered after including student's mother tongue and ICT tools. These findings suggest a need to expand this implementation with learners of different proficiency levels who also find it difficult to verbally express their ideas. Moreover, it takes a look at the use of the mother tongue as an advantage rather than as an obstacle to learning a foreign language.

Authors: Sebastian Paul
Published: June 2020

This study was conducted in order to better understand how, if at all, language centers (LCs) are relevant in current technological and methodological contexts of second language education. Five language centers housed by four different institutions of higher education in the western United States were examined. Two representatives from each of the five centers were interviewed either in-person or over the phone (N = 10). Data was collected in the form of semi-structured interviews and on-site visits. The data was analyzed using a flexible combination of multi-level qualitative coding, descriptive statistics, and narrative analysis. This study confirms recent findings that have shown LCs to be a highly diverse group of institutions, particularly with respect to form and function. With respect to relevance, a common framework for discussing different language centers is outlined in the form of three paradigms: center/department, center/institution, and center/community.

Classifying Emergency Tweets for Disaster Response
Authors: Lamsal Rabindra , Kumar T. V. Vijay
Published: June 2020

During disaster events such as floods, landslides, earthquakes, tsunamis, fire hazards, etc., social media platforms provide easy and timely access to information regarding the ongoing crisis events and thereby become an essential vehicle of information sharing. During such events, great amounts of such socially generated data becomes available, which can be accessed and processed to extract situational awareness insights. These insights, in turn, can be used to enhance the effectiveness and efficiency of disaster response in order to minimize the loss of lives and damage to property. People actively use social platforms like Facebook and Twitter to post information related to crisis events. Further, these platforms provide people the location and safety status of their family and friends during such events. Twitter, the microblogging platform, witnesses thousands of informally written tweets during crisis events, and since it provides high-level APIs to access its near real-time feed, it has become the primary source of data for researchers. It is generally observed that there is an exponential burst in the number of tweets during an ongoing crisis event. This sudden burst makes the task of monitoring, identifying, and processing each tweet virtually impossible for a human. However, such voluminous data can be processed using various machine learning and natural language processing techniques in coordination with a certain level of human interventions. This paper is focused on designing a semi-automated artificial intelligence-based classifier, which can classify the plethora of disaster-related tweets into various categories such as community needs, loss of lives, damage.

Published: June 2020

The work explores the use of street network analysis on informal settlements and discusses the potential and limitations of this methodology to advance disaster risk reduction and urban resilience. The urban network analysis tool is used to conduct graph analysis measures on street networks in three informal settlements in the LAC region: Portmore, Jamaica; Tegucigalpa, Honduras; and Lima, Peru. Authors incorporate risk variables identified by these communities and combine them with prospective scenarios in which street networks are strategically intervened to improve performance. Authors also compute one graph index named Reach centrality. Results are presented spatially through thematic maps, and statistically by plotting cumulative distributions. Findings show that centrality measures of settlements' networks helped identify key nodes or roads that may be critical for people's daily life after disasters, and strategic to improve accessibility. The proposed methodology shows potential to inform decisions on urban planning and disaster risk reduction.

Published: June 2020

A smart public library holds crucial roles in the current fast-moving smart environment. This study defines what constitutes a smart library and outlines the critical challenges affecting the readiness of the library to adopt a smart library in developing countries. Using a case study encompassing documentation analysis and in-depth interviews with 13 public officials at the Regency of Bojonegoro, Indonesia, this study demonstrates that expensive ICTs expenditures does not necessarily mean achieving a smart library. The findings showcase that a smart library started from the innovative and inventive programs and services that are progressively geared toward achieving the library as a place for the co-production of knowledge. The findings further demonstrate that technology per se is not the most critical challenge for a smart library. The findings highlight data awareness, organizational issues, insufficient policies and regulations, and public concerns as more significant challenges to the adoption of a smart library than technological capability and infrastructure.
A Simulation-Based Planning Methodology for Decreasing Patient Waiting Times in Pure Walk-In Clinics
Authors: Perez Eduardo , Anandhan Vivekanand , Novoa Clara
Published: June 2020

This article presents a simulation-based planning methodology that aims to improve patient service quality in pure walk-in clinics. Capacity planning is one of the major challenges in walk-in clinics because of the uncertainty in both patient demand and arrival times. This work presents a discrete-event simulation model for walk-in clinics that takes into consideration patient behavior in terms of arrival times for capacity planning at the clinic level. The goal of the model is to provide a tool that will allow clinics to develop protocols that will reduce patient waiting times by scheduling doctor and medical assistants considering demand uncertainties. A case study is presented to illustrate the benefits of the methodology. The results of the computational study show that by allocating the right number of resources at particular times of the day, walk-in clinics can achieve operational steady state while providing services to patients with minimum waiting times. The tool can be adapted and used to support any walk-in clinic.

Published: June 2020

Drawing on consumer socialization theory, this research investigates the impact of egoism, sense of belonging, and internet usage on young Chinese consumers' electronic word of mouth (eWOM). Normative and informative internet mediates the relationship between internet usage and eWOM. Furthermore, the role of TAM factors was explored in the structured model. A total of 876 Chinese consumers participated in the online survey. Structure equation modeling was adopted in the data analysis stage. The findings suggest that egoism, sense of belonging, and internet usage have positive influences on electronic word of mouth. Two factors of TAM (perceived usefulness and perceived ease of use) significantly moderates the relationship between egoism, sense of belonging, and e-WOM. Finally, informative and normative internet significantly mediates the relationship between internet usage and e-WOM. This study provides deeper understanding of young Chinese consumers' internet usage behavior. Implications for academicians and managers are discussed.

Indonesia coal ash is predicted to reach 10.8 million tons in the year 2020 but its utilization is still limited. In the last decade, coal ash has become a promising REY source candidate. To determine the potency of REY in Indonesia coal ash, information about element concentration and mineralogy of the ash is essential. In this study, coal ash samples were taken from Paiton-2, Pacitan, Rembang, and Tanjung Jati coal-fired power plants. Element content and mineralogy were analyzed using Inductive Couple Plasma Mass Spectroscopy/Atomic Emission Spectroscopy (ICP-MS/AES), X-Ray Diffractometer (XRD) and petrographic. The results showed that coal fly ash and bottom ash contains critical REY in the range of 38% to 41% with Coutlook larger than one. XRD analysis showed that both fly ash and bottom ash have similar mineral phases with slightly different concentrations. The mineral phase is dominated by amorphous glass, quartz, Fe-bearing minerals, and unburned carbon. The amorphous glass phase in fly ash is in the range of 23 to 34% while in bottom ash between 14 and 34%. Unburned carbon content in fly ash and bottom ashes are 7-13% and 7-19%, respectively. Fe-bearing mineral content in fly ash is 15-20% and bottom ash is 13-20%. In addition, Indonesia coal ash has a higher Heavy-REY enrichment factor than Light-REY. The Enrichment Factor of HREY in fly ash is as much as 1.3 times (in average) of the bottom ash.

Authors: Syamsiro Mochamad , Aridito Muhammad Noviansyah , Ma'arif Syamsul
Published: June 2020

Indonesia is a tropical country which become one of the largest producer country of biomass especially from agricultural and forestry sector. One of the biomass source that has not been widely utilized is sago. Sago is an alternative source of carbohydrates besides rice, especially in the eastern region such as Papua. The potential of sago in Papua was 66,593 tons in 2018. This potential produces sago waste from processing sago starch, which can pollute the environment. Utilization of sago waste in the form of sago production waste as a source of biomass for electricity generation is an alternative solution. The result shows that sago pulp can be processed into briquettes with the calorific value of 6,327.4 kcal/kg – 6,946.7 kcal/kg. Sago production waste generated from the processing of sago starch is 14% so that the daily waste potential is 25.54 tons/day. Based on this potential, OWRS technology using pyrolysis-gasification obtained 6.6 tons/day of sago charcoal briquettes. The potential of heat energy was 42.03 Gcal/day. The potential of electricity that can be produced with updraft-fixed bed gasification from sago charcoal briquettes was 5.18 MWh. The theoretical power is 2.03 MW with an output power of 215.83 kW at 11% efficiency.

Plastic shopping bags are easy to obtain for free or at low prices, hence contribute as the highest quantity among plastic waste. The plastic shopping bags waste has no economic value. Usually they are just thrown away. An alternative solution is by utilizing them to produce paving block by mixing with sands. The objective of this experiment is to evaluate the best ratio composition of plastic shopping bags waste and sand, followed by evaluation of the physical-mechanical properties of this particular paving block. Several different mixture ratios of weights of plastic shopping bag and sand were evaluated to obtain the best physical-mechanical properties of the paving block. The mixture ratios of weight of plastic shopping bags waste and sand were 1:1, 1:2, 1:3, 1:4 and 1:5, respectively. The shopping plastic bags waste was melted before mixed with sand. The different mixture ratios were mixed with same pressure. The paving block mixture with ratio of 1:4 exhibited the best physical-mechanical properties as revealed by no defect, no crack and fine surface. The compressive strength of 17.4 MPa, friction resistance of 0.138 mm/sec and water absorption of 2.518% can be achieved, which is suitable for parking area construction.

However, the use of polystyrene has become a problem for the environments because its properties are difficult to be degraded by nature. Pyrolysis method can be regarded as one of the environmentally friendly methods for recycling polystyrene waste. This research aims to investigate the effect of bentonite and natural zeolite catalyst on the pyrolysis of polystyrene. The experiment was carried out in a batch process. The pyrolysis process consists of a cylindrical reactor with electrical heater, a condenser, and a liquid product container. About 100 grams of polystyrene material was pyrolysis per batch. Catalysts used in the variation of 0%, 10%, 15%, 20%, and 25% of polystyrene. The liquid product was collected in 60 minutes and weighed. The composition of the liquid product was determined by gas chromatography. Polystyrene pyrolysis utilizes bentonite and natural zeolite as the catalyst. It produces benzene, toluene, ethylbenzene, styrene, and isopropyl benzene as the liquid product, and polystyrene residue as a solid product. Among the catalyst studied, bentonite is found to be the most efficient and increase the styrene selectivity (30.28 wt%) significantly at a reaction temperature of 400°C in comparison to the natural zeolite catalyst.

This study recorded distribution and size of alfalfa weevil (Hypera postica(Gyllenhal); Coleoptera: Curculionidae) populations in Saskatchewan, Canada, from 2001 to 2014. The spread of alfalfa weevil across the province, originally southwest to southeast, was northward and westward during this time. By 2014, only northwestern and west central areas remained relatively alfalfa weevil free. From a minor pest in 2001, the alfalfa weevil increased to be the principal insect pest of alfalfa (Medicago sativaLinnaeus; Fabaceae) in 2014. The parasitoidBathyplectes curculionis(Thomson) (Hymenoptera: Ichneumonidae) had a similar distribution. Other parasitoids collected includedOomyzus incertus(Ratzeburg) (Hymenoptera: Eulophidae) andMicroctonus colesiDrea (Hymenoptera: Braconidae). Conservation of these parasitoids is an important step in maximising their effectiveness as alfalfa weevil biocontrol agents. Molecular sequencing of the DNA barcoding region of specimens identified morphologically asB. curculionisindicated moderately high levels of sequence divergence among specimens (up to 5.8%); however, interspecific genetic variation between other species ofBathyplectesFörster was also high. Therefore, we conclude thatB. curculioniswas the onlyBathyplectesspecies collected in our study. An illustrated key to the described species ofBathyplectesin North America is provided, as well as DNA barcodes of most species, including five distinct barcodes in theBathyplectes curculionis–B. exiguus(Gravenhorst) species complex.
The impact of nutrition and lifestyle on male fertility

Published: June 2020

Background and aims: Male unexplained infertility has long been suspected to result from environmental, lifestyle and nutritional factors. However, the literature on the subject is still scarce, and clinical studies providing robust evidence are even scarcer. In addition, some similar studies come to different conclusions. Dietary pattern can influence spermatogenesis by its content of fatty acids and antioxidants. Yet, in an age of industrialized mass food production, human bodies become more exposed to the ingestion of xenobiotics, as well as chemicals used for production, preservation, transportation and taste enhancement of foods. We attempted in this paper to collect the available evidence to date on the effect of nutritional components on male fertility. Material and methods: A systematic search of the relevant literature published in PubMed, ScienceDirect and Cochrane Central Register of Controlled Trials Database was conducted. Literature was evaluated according to the Newcastle-Ottawa- Scale. Results: Epidemiological observations are concordant in demonstrating an association of low-quality sperm parameters with higher intake of red meat, processed and organ meat and fullfat dairy. On the contrary, better semen parameters were observed in subjects consuming a healthy diet, rich in fruit, vegetables, whole grains and fish. Evidences of the negative impact on male fertility of by-products of water disinfection, accumulation in food chain of persistent organochlorine pollutants, pesticides, phthalates from food and water containers and hormones used in breeding cattle have been reported. Clinical trials of the effects of micronutrients on semen parameters and outcomes of assisted fertilization are encouraging, although optimal modality of treatment should be established. Conclusions: Although quality of evidence should be ameliorated, it emerges that environmental factors can influence male fertility. Some nutrients may enhance fertility whereas others will worsen it. With diagnostic analysis on a molecular or even sub-molecular level, new interactions with micronutrients or molecular components of our daily ingested foods and leisure drugs may lead to a better understanding of so far suspected but as yet unexplained effects on male spermatogenesis and fertility.

Objective: In this study, we aimed to determine the predictive factor for additional treatment requirement in active surveillance (AS) for patients with low or very low-risk prostate cancer (PCa) and we investigated the effect of tumor burden by total core involvement rate in biopsy to predict of need for additional treatment.Material and methods: 107 patients with PCa in AS between 2005 and 2018 have been evaluated retrospectively. Groups were divided into two groups according to the need for additional treatment. Group 1 received additional treatment, group 2 did not receive additional treatments and active surveillance was continued. Patient’s total prostate-specific antigen (tPSA), prostate-specific antigen density (PSA-D), total core involvement count, quantity and rate at biopsy pathology results and follow-up period were recorded and compared in the two groups. Results: The current cohort includes 107 patients. Mean age at diagnosis was 63.01years. Mean tPSA values at diagnosis were 6.09 ng/mL and 5.2 ng/mL in the group 1 and group 2, respectively. Mean follow-up period was 38.1 months (range, 12 to 134 months). Only PSA-D measurement significantly predicted need for additional treatment (p = 0.017). ROC analysis showed that the optimal threshold was 0.13 ng/mL/cc (sensitivity: 70.8%; specificity: 57.1%). Additional treatment requirement was not detected in patients with PSA-D cut-off level less than 0.07 ng/mL/cc. Conclusions: Total tumor burden of less than 5% is safe for patients with low or very low-risk PCa in AS. A 0.13 ng/mL/cc cut-off level of PSA-D can predict to need for additional treatment in patients managed by AS.

Sport-related spine injury can be devastating and have long-lasting effects on athletes and their families. Providing evidence-based care for patients with spine injury is essential for optimizing postinjury outcomes. When caring for an injured athlete in American tackle football, clinicians must make decisions that involve unique challenges related to protective equipment (eg, helmet and shoulder pads). The Spine Injury in Sport Group (SISG) met in Atlanta, Georgia, March 2–3, 2019, and involved 25 health care professionals with expertise in emergency medicine, sports medicine, neurologic surgery, orthopaedic surgery, neurology, physiatry, athletic training, and research to review the current literature and discuss evidence-based medicine, best practices, and care options available for the prehospital treatment of athletes with suspected cervical spine injuries.1,2 That meeting and the subsequent Mills et al publication delineate the quality and quantity of published evidence regarding many aspects of prehospital care for the athlete with a suspected cervical spine injury. This paper offers a practical treatment guide based on the experience of those who attended the Atlanta meeting as well as the evidence presented in the Mills et al article. Ongoing research will help to further advance clinical treatment recommendations.
Threefolds fibred by mirror sextic double planes
Authors: Kooistra Remkes , Thompson Alan
Published: June 2020

We present a systematic study of threefolds fibred by K3 surfaces that are mirror to sextic double planes. There are many parallels between this theory and the theory of elliptic surfaces. We show that the geometry of such threefolds is controlled by a pair of invariants, called the generalized functional and generalized homological invariants, and we derive an explicit birational model for them, which we call the Weierstrass form. We then describe how to resolve the singularities of the Weierstrass form to obtain the “minimal form”, which has mild singularities and is unique up to birational maps in codimension 2. Finally, we describe some of the geometric properties of threefolds in minimal form, including their singular fibres, canonical divisor, and Betti numbers.
