Published: December 2019

OBJECTIVE

Low registration errors are an important prerequisite for reliable navigation, independent of its use in cranial or spinal surgery. Regardless of whether navigation is used for trajectory alignment in biopsy or implant procedures, or for sophisticated augmented reality applications, all depend on a correct registration of patient space and image space. In contrast to fiducial, landmark, or surface matching–based registration, the application of intraoperative imaging allows user-independent automatic patient registration, which is less error prone. The authors’ aim in this paper was to give an overview of their experience using intraoperative CT (iCT) scanning for automatic registration with a focus on registration accuracy and radiation exposure.

METHODS

A total of 645 patients underwent iCT scanning with a 32-slice movable CT scanner in combination with navigation for trajectory alignment in biopsy and implantation procedures (n = 222) and for augmented reality (n = 437) in cranial and spine procedures (347 craniotomies and 42 transsphenoidal, 56 frameless stereotactic, 59 frame-based stereotactic, and 141 spinal procedures). The target registration error was measured using skin fiducials that were not part of the registration procedure. The effective dose was calculated by multiplying the dose length product with conversion factors.

RESULTS

Among all 1281 iCT scans obtained, 1172 were used for automatic patient registration (645 initial registration scans and 527 repeat iCT scans). The overall mean target registration error was 0.86 ± 0.38 mm (± SD) (craniotomy, 0.88 ± 0.39 mm; transsphenoidal, 0.92 ± 0.39 mm; frameless, 0.74 ± 0.39 mm; frame-based, 0.84 ± 0.34 mm; and spinal, 0.80 ± 0.28 mm). Compared with standard diagnostic scans, a distinct reduction of the effective dose could be achieved using low-dose protocols for the initial registration scan with mean effective doses of 0.06 ± 0.04 mSv for cranial, 0.50 ± 0.09 mSv for cervical, 4.12 ± 2.13 mSv for thoracic, and 3.37 ± 0.93 mSv for lumbar scans without impeding registration accuracy.

CONCLUSIONS

Reliable automatic patient registration can be achieved using iCT scanning. Low-dose protocols ensured a low radiation exposure for the patient. Low-dose scanning had no negative effect on navigation accuracy.

Published: December 2019

OBJECTIVE

In the last several decades, various factors have been studied for a better evaluation of the risk of rupture in incidentally discovered intracranial aneurysms (IAs). With advanced MRI, attempts were made to delineate the wall of IAs to identify weak areas prone to rupture. However, the field strength of the MRI investigations was insufficient for reasonable image resolution in many of these studies. Therefore, the aim of this study was to analyze findings of IAs in ultra–high field MRI at 7 Tesla (7 T).

METHODS

Patients with incidentally found IAs of at least 5 mm in diameter were included in this study and underwent MRI investigations at 7 T. At this field strength a hyperintense intravascular signal can be observed on nonenhanced images with a brighter “rim effect” along the vessel wall. Properties of this rim effect were evaluated and compared with computational fluid dynamics (CFD) analyses.

RESULTS

Overall, 23 aneurysms showed sufficient image quality for further evaluation. In 22 aneurysms focal irregularities were identified within this rim effect. Areas of such irregularities showed significantly higher values in wall shear stress and vorticity compared to areas with a clearly visible rim effect (p = 0.043 in both).

CONCLUSIONS

A hyperintense rim effect along the vessel wall was observed in most cases. Focal irregularities within this rim effect showed higher values of the mean wall shear stress and vorticity when compared by CFD analyses. Therefore, these findings indicate alterations in blood flow in IAs within these areas.
When imaging meets neurophysiology: the value of navigated transcranial magnetic stimulation for preoperative neurophysiological mapping prior to brain tumor surgery
Authors: Raffa Giovanni , Quattropani Maria Catena , Germanò Antonino
Published: December 2019

Maximal safe resection is the modern goal for surgery of intrinsic brain tumors located in or close to brain eloquent areas. Nowadays different neuroimaging techniques provide important anatomical and functional information regarding the brain functional organization that can be used to plan a customized surgical strategy to preserve functional networks, and to increase the extent of tumor resection. Among these techniques, navigated transcranial magnetic stimulation (nTMS) has recently gained great favor among the neurosurgical community for preoperative mapping and planning prior to brain tumor surgery. It represents an advanced neuroimaging technique based on the neurophysiological mapping of the functional cortical brain organization. Moreover, it can be combined with other neuroimaging techniques such as diffusion tensor imaging tractography, thus providing a reliable reconstruction of brain eloquent networks. Consequently, nTMS mapping may provide reliable noninvasive brain functional mapping, anticipating information that otherwise may be available to neurosurgeons only in the operating theater by using direct electrical stimulation. The authors describe the reliability and usefulness of the preoperative nTMS-based approach in neurosurgical practice, and briefly discuss their experience using nTMS as well as currently available evidence in the literature supporting its clinical use. In particular, special attention is reserved for the discussion of the role of nTMS as a novel tool for the preoperative neurophysiological mapping of motor and language networks prior to surgery of intrinsic brain tumors located in or close to eloquent networks, as well as for future and promising applications of nTMS in neurosurgical practice.
Resting-state network mapping in neurosurgical practice: a review
Authors: Hacker Carl D. , Roland Jarod L. , Kim Albert H. , Shimony Joshua S. , Leuthardt Eric C.
Published: December 2019

Resting-state functional MRI (rs-fMRI) is a well-established method for studying intrinsic connectivity and mapping the topography of functional networks in the human brain. In the clinical setting, rs-fMRI has been used to define functional topography, typically language and motor systems, in the context of preoperative planning for neurosurgery. Intraoperative mapping of critical speech and motor areas with electrocortical stimulation (ECS) remains standard practice, but preoperative noninvasive mapping has the potential to reduce operative time and provide functional localization when awake mapping is not feasible. Task-based fMRI has historically been used for this purpose, but it can be limited by the young age of the patient, cognitive impairment, poor cooperation, and need for sedation. Resting-state fMRI allows reliable analysis of all functional networks with a single study and is inherently independent of factors affecting task performance. In this review, the authors provide a summary of the theory and methods for resting-state network mapping. They provide case examples illustrating clinical implementation and discuss limitations of rs-fMRI and review available data regarding performance in comparison to ECS. Finally, they discuss novel opportunities for future clinical applications and prospects for rs-fMRI beyond mapping of regions to avoid during surgery but, instead, as a tool to guide novel network-based therapies.

Published: December 2019

OBJECTIVE

With the revised WHO 2016 classification of brain tumors, there has been increasing interest in imaging biomarkers to predict molecular status and improve the yield of genetic testing for diffuse low-grade gliomas (LGGs). The T2-FLAIR–mismatch sign has been suggested to be a highly specific radiographic marker of isocitrate dehydrogenase (IDH) gene mutation and 1p/19q codeletion status in diffuse LGGs. The presence of T2-FLAIR mismatch indicates a T2-hyperintense lesion that is hypointense on FLAIR with the exception of a hyperintense rim.

METHODS

In accordance with PRISMA guidelines, we performed a systematic review of the Ovid Medline, Embase, Scopus, and Cochrane databases for reports of studies evaluating the diagnostic performance of T2-FLAIR mismatch in predicting the IDH and 1p/19q codeletion status in diffuse LGGs. Results were combined into a 2 × 2 format, and the following diagnostic performance parameters were calculated: sensitivity, specificity, positive predictive value, negative predictive value, and positive (LR+) and negative (LR−) likelihood ratios. In addition, we utilized Bayes theorem to calculate posttest probabilities as a function of known pretest probabilities from previous genome-wide association studies and the calculated LRs. Calculations were performed for 1) IDH mutation with 1p/19q codeletion (IDHmut-Codel), 2) IDH mutation without 1p/19q codeletion (IDHmut-Noncodel), 3) IDH mutation overall, and 4) 1p/19q codeletion overall. The QUADAS-2 (revised Quality Assessment of Diagnostic Accuracy Studies) tool was utilized for critical appraisal of included studies.

RESULTS

A total of 4 studies were included, with inclusion of 2 separate cohorts from a study reporting testing and validation (n = 746). From pooled analysis of all cohorts, the following values were obtained for each molecular profile—IDHmut-Codel: sensitivity 30%, specificity 73%, LR+ 1.1, LR− 1.0; IDHmut-Noncodel: sensitivity 33.7%, specificity 98.5%, LR+ 22.5, LR− 0.7; IDH: sensitivity 32%, specificity 100%, LR+ 32.1, LR− 0.7; 1p/19q codeletion: sensitivity 0%, specificity 54%, LR+ 0.01, LR− 1.9. Bayes theorem was used to calculate the following posttest probabilities after a positive and negative result, respectively—IDHmut-Codel: 32.2% and 29.4%; IDHmut-Noncodel: 95% and 40%; IDH: 99.2% and 73.5%; 1p/19q codeletion: 0.4% and 35.1%.

CONCLUSIONS

The T2-FLAIR–mismatch sign was an insensitive but highly specific marker of IDH mutation and IDHmut-Noncodel profile, although significant exceptions may exist to this finding. Tumors with a positive sign may still be IDHwt or 1p/19q codeleted. These findings support the utility of T2-FLAIR mismatch as an imaging-based biomarker for positive selection of patients with IDH-mutant gliomas.

Monocyte to HDL ratio as an indicator of subclinical atherosclerosis in diabetic retinopathy
Authors: KAN Seyfullah , KARAİBRAHİMOĞLU Adnan
Published: December 2019

ABSTRACTAim: Incidence of cardiovascular
diseases is gradually increasing in patients with diabetic retinopathy (DR).
MHR (Monocyte/HDL ratio), is a novel marker related with cardiovascular and
cerebrovascular diseases. The aim of this study was to investigate the
relationship between a subclinical atherosclerosis marker, carotid intima media
thickness (CIMT), and MHR in diabetic retinopathy patients without an apparent
cardiovascular disease. 

Material
and Method: 106 diabetic patients without an apparent
cardiovascular disease and 35 healthy controls matched for age, gender and body
mass index (BMI) were included in this study. 
The patients were separeted into four groups which were proliferative
diabetic retinopahy (PDR , n=30), nonproliferative diabetic retinopathy (NPDR,
n=35), diabetic patients without retinopathy (n=41) and control group (n=35).
Anthropometric, biochemical parameteres and CIMT were measured. Correlation and
regression analysis were done to assess the relation between MHR and CIMT.

Results:
MHR was
significantly different between
groups and significantly higher in PDR group (p < .001). CIMT, a marker for atherosclerosis, significantly
differed between groups (p <
.001). CIMT levels were significantly higher in PDR while similar values were
found in other than groups. In PDR group, a significant correlation was found
between MHR and CIMT ( r=0.96; p < .001). According to binary logistic regression analysis,
MHR had a significant effect on CIMT [ β=0.206, (%95 CI : 1.004-1.505), P=0.046
].

Conclusion: This study showed that  in patients with diabetic retinopathy, high
levels of MHR which is a non-invasive, simple and inexpensive marker, might be
useful for determination of subclinical cardiovascular risk. This study which
is the first in literature that investigated the relation between MHR and CIMT
in diabetic retinopathy might have a benefit on early detection of cardiac risk
in diabetic patients without an apparent cardiovascular disease.

BACKGROUND:

Despite established guidelines for bladder cancer (BC) management, significant treatment variability remains across the United States.

OBJECTIVE:

To report the impact of a tertiary center, bladder cancer multidisciplinary clinic (BCMC) on diagnostic evaluation and treatment recommendations in externally referred patients with BC.

METHODS:

Our BCMC clinic format includes simultaneous consultation with urologic, medical and radiation oncology, with real-time expert genitourinary pathology and radiology review. We retrospectively assessed all external referrals for concordance between outside radiology/pathology records and BCMC interpretation after central review and explored potential differences between outside treatment plan and BCMC recommendations.

RESULTS:

233 patients with BC were referred to BCMC between the years 2014–2017. Complete radiographic and pathology data were available for 201 patients. Median age was 69 (Interquartile Range: 60–75) and 83% were performance status ECOG 0-1. After BCMC review of outside records, imaging interpretation was changed in 53 (26%) patients; pathology was changed in 59 (29%). Further diagnostic work-up was recommended in 85 (42%) patients. Overall, 56 (28%) patients had a change in their clinical staging. BCMC recommended treatment modification in 117 (58%) patients. Subsequent treatment plan was concordant with BCMC recommendations 91.5% of the time.

CONCLUSIONS:

BCMC resulted in critical radiology and/or pathology diagnostic changes in several cases, with frequent treatment modifications, underscoring the importance of multidisciplinary care in BC and the considerable contribution of real-time expert pathology and radiology review in diagnostic accuracy. Further studies are needed to confirm the proposed benefits and impact of BCMC on treatment response and patient outcomes.

Authors: Rastgardani Tara , Armstrong Melissa J. , Gagliardi Anna R. , Grabovsky Arthur , Marras Connie
Published: December 2019

Background:

OFF periods impair quality of life in Parkinson’s disease but the nature and degree of this impact is largely unquantified. Optimal treatment relies on assessing the experience and impact of these periods on patients and their carepartners.

Objectives:

To understand the experience and impact of OFF periods on their lives.

Methods:

Informed by qualitative interviews we designed questionnaires and surveyed neurologists, people with Parkinson’s disease and carepartners.

Results:

50 general neurologists, 50 movement disorder neurologists, 442 patients (median disease duration 5 years) and 97 carepartners were included. The most common OFF symptoms reported by patients and carepartners were stiffness, slowness of movement and changes in gait. Non-motor symptoms were less common. A higher proportion of carepartners reported each symptom. A minority of neurologists recognized pain, sweating and anxiety as possible symptoms of OFF periods. The three OFF symptoms most frequently designated as having great impact by people with Parkinson’s disease were changes in gait, slowness and stiffness. In contrast, cognitive impairment was most frequently rated as having great impact on carepartners. OFF periods were reported to impact many aspects of the lives of both patients and carepartners.

Conclusions:

In people with Parkinson’s disease of under 10 years duration, motor symptoms of OFF periods predominate in impact, however cognitive impairment has great impact on carepartners. Education is needed for neurologists regarding the non-motor aspects of OFF. The importance of involving carepartners in the assessment regarding OFF periods is supported by the higher frequency of symptom reporting by carepartners, and the significant impact on their lives.

Authors: Cilloni Giada , Leporati Rebecca , Rizzi Antonio , Romagnoli Giovanni
Published: December 2019

Fashion and apparel retail have been driving the adoption of RFID for the last 10 years. This paper strives to present an overview of the current adoption of RFID technology in this sector and to improve the understanding of the evolution of use cases (UCs) over time by proposing a framework for the UC lifecycle. This tool allows us to classify UCs with six different labels (core, intermittent, trendy, vintage, innovative or ghost) according to three dimensions. We analysed and classified more than 220 scientific papers, magazine articles, white papers, web news stories and press releases as well as confidential information from system integrators dealing with UHF RFID projects in fashion and apparel retail in recent decades. We are not aware of any other study covering this issue, and the results we obtain represent an updated and thorough overview of UHF RFID adoption in the fashion industry. We believe that, by keeping the framework updated, we could create a barometer of RFID adoption in fashion and apparel retail while obtaining further insights on UC evolution over time.

Published: December 2019

In India, there are about 1.5–2 million estimated cancer cases. Early detection can significantly reduce the mortality rate. This paper focuses on planning an ultra-wideband directional Microwave imaging system to detect cancer cells. Microwave imaging uses the scattering wave or reflected wave that arises from the contrast in dielectric properties between normal and malignant breast tissues. Microwave breast imaging, which is non-invasive and harmless to human, offers a promising alternative method to mammography. A compact, ultra wideband (UWB) planar antenna for the Microwave thermography system is designed and simulated using two commercial software, CST Microwave studio and HFSS stimulators. The proposed technique depends on the significant contrast in the dielectric properties of the normal and tumor tissues.

Published: December 2019

In precast concrete, a connection is needed to unite the components so that they become a whole unified structure. This study aims to determine the reinforcement strength and length of reinforcement in precast concrete connections. To paste reinforcement into precast concrete, giving additional material in the form of grouting which is called sika grout 215 and functions as an adhesive is necessary. Pullout testing is carried out in the laboratory, and its simulation by modeling uses the finite element method based software. This research is divided into 2 phases. The first phase is making specimen to examine the bond strength between the concrete and reinforcement that has been given sika grout 215. So monolithic specimen is made as a comparison. The result of the bond strength of the monolithic test specimen is 6.24 MPa, and the sika grout 215 category is 6.52 MPa. From the experimental results in the laboratory with modeling, it is obtained the bond strength ratio of 0.94. The length of development (ld) based on the results of the testing phase I of 200 mm. The second phase is examining the damage pattern due to the stress that occurred. Specimens are made into 4 categories, namely modeling developments with the length of 120 mm (<40% ld), with the length of 160 mm (<20% ld), with length of 200 mm (= ld), and with the length of 260 mm(> 30% ld) both for monoliths and sika grout 215. The damage pattern, which is in the form of yielding and breaking reinforcement as the result of the pullout experiment in the laboratory shows not much different from the result of simulation using the software.

В даній статті досліджуються питання щодо сутності публічного обвинувачення, як основної кримінально-процесуальної функції прокурора. Аналізуються точки зору вчених, щодо моменту виникнення обвинувальної функції у кримінальному процесі та її змісту. Наводяться аргументи відносно того, що підтримання публічного обвинувачення - це го­ловна і єдина кримінально-процесуальна функція прокурора при розгляді матеріалів кримі­нального провадження судом першої інстанції, яка займає домінуюче становище у системі кримінально-процесуальних функцій. Зазначається, що виконання прокурором у суді про­цесуальної функції обвинувачення - це практична реалізація тих висновків, до яких він прийшов на стадії досудового розслідування. Функція обвинувачення, що виконується про­курором у кримінальному судочинстві, спрямована не тільки на висунення обвинувачення і доведення його перед судом, а виступає також правовим засобом захисту інтересів особи, держави і суспільства від злочинних посягань в цілому.

Aðskilnaður ríkis og kirkju. Upphaf almennrar umræðu 1878–1915. Síðari grein
Authors: Hugason Hjalti
Published: December 2019

The Icelandic Constitution from 1874 constituted a national church and religious freedom in the country, instead of the former evangelical-lutheran state-religion. Only four years later discussions began about whether a national church and religious freedom were compatible or if it was necessary to choose the one or the other.
In an article published in the last number of this journal it was shown how two opposite viewpoints regarding this question had already developed by 1880. The first one, “the way of separation”, was driven by human-rights perspectives, aiming to establish real religious freedom for everybody. The other one, “the way of legislation”, was based on religious and ecclesiastic perspectives. Those who followed the second one, wanted to develop an independent national church, with ongoing relations with the state.
In this second article, particular themes of the debate on separation between church and state are analyzed, and various views on the topic expressed in religious bulletins and journals examined. The main focus will be on the financial relationship between the state and the church after separation had taken place, and the question of public education, which was the responsibility of the national church until 1907. To conclude with, it will be shown how the criticism of separatists were met by constitutional amendments in 1915. Finally,
the interpretation that discussions about separation of state and church during the period 1878–1915 should be seen as a part of the national freedom struggle of the Icelandic people is rejected.
Textaraðirnar og kirkjuárið í sögulegu ljósi

The topic of this thesis is to show how the texts of the pericopae of the ancient church evolved in conjunction with collection of Christian sacred writings. It is noticeable in that the texts which became part of the pericope had to meet certain criteria, for example to be multifaceted and open to interpretation. In the formulation of the church year, it was not possible to maintain continuous linear reading, but the texts had to form one whole. In the history of the Church, two traditions evolved. First of all, reading and interpretation of the text of the pericope on Sundays, and secondly, a continuous reading of texts outside the pericope on other days of the week. By the time of the Reformation, this tradition split into two different strands. In Lutheran churches the text of the ancient church was used, while in churches based on Calvin’s and Zwingli’s theological traditions, lectio continua or selected texts were used. A research of the history of the first series of the pericopae in Iceland, has shown that this series has been shaping the readings within the Icelandic church since AD 999/1000, and that it has been predominant within the common history of Christianity and the Icelandic people.
The Relations between Student Cynicism and Students’ Life Satisfaction
Authors: KASALAK Gamze
Published: December 2019

The purpose of this study is to determine the relationship between student cynicism and students’ life satisfaction. This study is in correlational survey model. The sample of the study consists of 554 Turkish high school students, who were selected by simple random sampling method. Findings show that female students have more cynical attitudes towards their schools than male students. And, female students are less satisfied with their school and living environment but more satisfied with their friends than male students. Students who think about studying at another school have higher levels of student cynicism but lower levels of school satisfaction and living environment satisfaction than those who do not think so. The findings reveal the negative relationships between student cynicism and students’ life satisfaction. The strongest relationship has been determined to be between institutional cynicism and reduced sense of school satisfaction. Path analysis indicates that four subscales of student cynicism affect students’ life satisfaction. It is possible to examine the premises that lead to the perception of student cynicism and their impacts. For future research, it is recommended to examine the ways to alleviate the negative effects of student cynicism and improve the outcomes.

What’s up with WhatsApp? A Critical Analysis of Mobile Instant Messaging Research in Language Learning
Authors: Kartal Galip
Published: December 2019

This paper is devoted to exploring the way how the mobile instant messaging WhatsApp is deployed to enhance the learning of a second or foreign language. Therefore, this study set out to investigate the empirical studies related to WhatsApp and language learning published in peer-reviewed journals. Thirty-seven studies were selected after a four-phase article identification procedure and a systematic review was conducted to investigate the effectiveness of WhatsApp on language learning. The analysis focused on the keywords, sample sizes, participants, data sets, duration, and language learning benefits of the studies. The results have shown that WhatsApp has been used diversely in language learning. The studies found evidence that WhatsApp can be used to improve the four language skills (i.e. reading, listening, writing, and speaking), integrated language skills, and vocabulary. Moreover, WhatsApp was found to be effective in increasing motivation and language attitudes, fostering learner autonomy, increasing interaction, and lowering language anxiety. The study also provided future research directions and recommendations for practice concerning how to appropriately employ mobile instant messaging in language learning.
IMPROVING THE SELF-AWARENESS CAPACITY OF SECONDARY SCHOOL STUDENTS BY FORMING A SCHOOL COUNSELING MODEL BASED ON STUDENT CAPACITY DEVELOPMENT ORIENTATION IN VIETNAM

Published: December 2019

The self-awareness capacity has long been no stranger in the foreign education, but in Vietnam, self-awareness capacity has only been developed in education in recent years. The self-awareness capacity related problems among Vietnamese students have been exacerbated such as gender-based violence, gender bias, wrong career choices, disorientation and school counseling activities currently could not support this difficulty for students. Based on the theoretical framework of self-awareness capacity from previous studies in Vietnam and further developing the aspects of self-awareness by age, the questionnaire had been done to survey of 726 lower-secondary school students and 474 upper-secondary school students to find the situation of their self-awareness capacity problems, as well as the need for self-awareness capacity problems counseling. The results demonstrated a positive correlation between self-awareness capacity problems and students’ need for self-awareness capacity problems counseling. In addition, identifying self-awareness capacity problems encountered by students helps us to develop a new school counseling model, as well as a process to counsel self-awareness capacity problems for students to enhance the self-awareness capacity and support school counseling activities effectively, also meeting the requirements of renewing the general curriculum in the students’ capacity development orientation in Vietnam. Keywords: self-awareness, self-awareness capacity, school counseling model, school counseling activities, student capacity development orientation.
EXPLORING THE BARRIERS TO EFFECTIVE COOPERATIVE LEARNING IMPLEMENTATION IN SCHOOL MATHEMATICS CLASSROOMS

Published: December 2019

Literature is replete with research confirming the benefits of cooperative learning on students’ academic achievement and attitude towards mathematics. Despite these benefits, cooperative learning implementation in most Zambian secondary school mathematics classrooms has remained a challenge. An explanatory sequential mixed methods research design was employed to determine the causes of teacher-resistance to cooperative learning implementation in selected schools. A cluster random sampling method was used to select 62 teachers (43 male and 19 female) of mathematics from six public secondary schools in Ndola district of Zambia. A questionnaire was administered to all the 62 teachers followed by lesson observations in six randomly selected grade 11 mathematics classrooms, whose teachers later attended a focus group discussion. Research findings revealed that the majority of participants prefer expository teaching to cooperative learning. More than 64% of the participants indicated that they resisted implementing cooperative learning in their classrooms due to shortcomings in; assessing learners, ensuring a disciplined class environment, completing the already bulky syllabus, handling large classes, students’ low reasoning abilities and preparation time versus high teaching loads. These results provide evidence on the need for more attention to how the identified challenges could be addressed not only in Zambian mathematics classrooms but in other educational settings elsewhere. Keywords: cooperative learning, expository teaching, mathematics classrooms, mixed methods research.

Grey seals Halichoerus grypus and harbour seals Phoca vitulina are common seal species in the North and Baltic seas and final hosts of Corynosoma acanthocephalans. C. strumosum and C. magdaleni infect the small intestines of both seal species. In contrast to harbour seals, Baltic grey seals in the past have regularly displayed severe C. semerme infections in the caecum and colon, with associated tunica muscularis hypertrophy, inflammation and ulcerations as part of the Baltic seal disease complex (BSDC). Pathogenesis and correlation of acanthocephalan infections with these lesions are still unknown. This study describes the intestinal pathology and parasitic distribution in each seal species. Grey seal (n = 83) and harbour seal (n = 1156) intestines of all age groups and sexes, collected in Poland, Germany and Estonia from 1998 to 2017, were investigated. Most harbour seals came from the North Sea, whereas grey seals were predominantly derived from the Baltic Sea. Both species featured mild to moderate small intestinal infections. Grey seals showed colonic infections not found in harbour seals and featured a chronic erosive to ulcerative, eosinophilic or lympho-plasmacytic colitis with tunica muscularis hypertrophy, indicating still prevailing clinical signs of the BSDC. Harbour seals displayed granulomatous, eosinophilic, lympho-plasmacytic or catarrhal enteritis. The prevalence of acanthocephalan infections in harbour seals increased from 2012 onwards. Furthermore, significant associations between acanthocephalan infection and the presence of intestinal inflammation were found for both seal species. This study suggests that the level of acanthocephalan infection and associated lesions are suitable seal population health indicators, with the colon being a specific target organ for Baltic grey seal health monitoring.
Urgent need for coral demography in a world where corals are disappearing
Authors: Edmunds PJ , Riegl B
Published: December 2019

Coral reefs have long attracted attention because of their biological and economic importance, but this interest now has turned to examining the possibility of functional extirpation. Widespread declines in coral abundances have fueled the shift in motivation for studying reefs and catalyzed the proliferation of monitoring to record the changes underway. Despite appreciation of monitoring as a scientific endeavor, its primary use has continued to be the quantification of cover of coral, macroalgae, and a few other space holders. The limitations of coral cover in evaluating the consequences of changing coral abundance were highlighted decades ago. Yet neglect of the tools most appropriate for this task (demographic approaches) and continuing emphasis on a tool (coral cover) that is not ideal, indicates that these limitations are not widely appreciated. Reef monitoring therefore continues to underperform with respect to its potential, thus depriving scientists of the approaches necessary to project the fate of coral reefs and test hypotheses focused on the proximal causes of declining coral cover. We make the case that the coral reef crisis creates a need for coral demography that is more acute now than 4 decades ago. Modern demographic approaches are well suited to meet this need, but to realize their potential, consideration will need to be given to the possibility of expanding ecological monitoring of coral reefs to provide the data necessary for demographic analyses of their foundation taxon, the Scleractinia.
Metabolic Status and Ghrelin Regulate Plasma Levels and Release of Ovarian Hormones in Layer Chicks

Published: December 2019

The aim of the present study was to examine the role of nutritional status, the metabolic hormone ghrelin and their interrelationships in the control of chicken hormones involved in the regulation of reproduction. For this purpose, we identified the effect of food deprivation, administration of ghrelin 1-18 and their combination on plasma levels of testosterone (T), estradiol (E), arginine-vasotocin (AVT) and growth hormone (GH) as well as the release of these hormones by isolated and cultured ovarian fragments. It was observed that food deprivation reduces plasma T and E and increases plasma AVT and GH levels. Food restriction also reduced the amount of E produced by isolated ovaries, but it did not affect the ovarian secretion of T and AVT. No ovarian GH secretion was detected. Ghrelin administered to ad libitum fed chickens did not affect plasma T and E levels, but it did increase plasma GH and AVT concentrations. Moreover, it partially prevented the effect of food deprivation on plasma E and AVT levels, but not on T or GH levels. Ghrelin administration to control birds promoted ovarian T, but not E or AVT release and reduced T and no other hormonal outputs in birds subjected to food restriction. Our results (1) confirmed the ovarian origin of the main plasma T and E and the extra-ovarian origin of the main blood AVT and GH; (2) showed that food deprivation-induced suppression of reproduction may be caused by suppression of T and E and the promotion of AVT and GH release; (3) suggest the involvement of ghrelin in control chicken E, AVT and GH output; and (4) indicates that ghrelin can either mimic or modify the effect of the intake of low calories on chicken plasma and ovarian hormones, i.e. it can mediate the effect of metabolic state on hormones involved in the control of reproduction.
