Enhancing Wave-CAIPI using an single-axis insert head gradient
Authors: Roos Thomas , Versteeg Edwin , Siero Jeroen 
Published: August 2023

Acceleration techniques like SENSE have enabled significant decreases in scan time, but the $$$G$$$-factor penalty on SNR limits attainable accelerations. Wave-CAIPI lowers this $$$G$$$-factor by spreading aliasing and taking advantage of the coil sensitivity distributions. A high performance single-axis insert gradient is utilised to increase the attainable wave amplitudes and thereby increasing the effectivity of Wave-CAIPI. Simulations and 7T phantom &amp; in-vivo acquisitions show significant improvements in $$$G$$$-factor when using Wave-CAIPI, especially when utilizing the higher performance of the insert gradient. Not only are the $$$G$$$-factors lower but also show increased spreading and lack hard edges, allowing for even faster acquisitions.

Published: August 2023

Brain alterations due to cumulative effects of impacts have been reported in rugby players. However, literature on long-term effects is scarce, and no study has been conducted to characterize potential spinal cord impairments. In this study using a multiparametric MR protocol dedicated to both brain and cord, and combining state-of-the-art T1 relaxometry and ihMT imaging, we observed diffuse T1 increase in the cervical spinal cord, together with increased T1 and decreased ihMTsat in specific brain WM tracts in retired players. These preliminary results also suggest early aging, tissue degeneration, iron accumulation, and different aging processes in retired players.

Authors: Lambert Benjamin , Forbes Florence , Tucholka Alan , Doyle Senan , Dojat Michel 
Published: August 2023

Efforts are required to design Deep Learning models that are not only powerful, but also capable of expressing the certainty of their predictions.
We evaluate 3 state-of-the-art techniques for uncertainty quantification : Monte-Carlo Dropout, Deep Ensemble, and Heteroscedastic models. Evaluation is illustrated on a task of automatic segmentation of White-Matter Hyperintensities in T2-weighted FLAIR MRI sequences of Multiple-Sclerosis patients. Analysis is performed at 3 different scales : the voxel, the lesion, and the whole image. Results indicate the superiority of the Heteroscedastic approach, which ranked first in both the uncertainty and segmentation tasks.

- The proposed method allows a comprehensive relaxation times estimation (T1, T2, T2*) on MRgRT systems. - The methodology was validated on phantom and volunteer for accuracy and reproducibility. - For T1 and T2, less than 5 % coefficient of variation was observed and less than 10 % for the T2*. - Trends on 5 patients show a slight decrease and a recovery for the T1 and T2 values in both the boost and whole prostate during their treatment. - The dispersion of T1 and T2 decreased for all patients for the whole prostate whereas it was stable for the boost.
In vivo validation and quantification of non-susceptibility frequency contrast obtained with DEEPOLE QUASAR
Authors: Jochmann Thomas , Haueisen Jens , Jakimovski Dejan , Zivadinov Robert , Schweser Ferdinand 
Published: August 2023

Sources of MRI phase contrast include magnetic susceptibility, chemical exchange, and tissue microstructure. The novel DEEPOLE QUASAR method disentangles frequency sources and yields separate maps for magnetic susceptibility and non-susceptibility frequency shifts. In this work, we validated the method in vivo and performed the first quantitative study of non-susceptibility frequency in the human brain. We found substantial non-susceptibility contributions in WM and GM. The quantification of non-susceptibility in the human brain provides new ground for theories on the origins of frequency contrast.

Published: August 2023

In this work a first human-sized Magnetic Particle Imaging (MPI) scanner designed and specifically engineered for experimental (cardio)vascular interventions is presented. Based on a novel open design implementing the so called traveling wave MPI approach, the open iMPI system provides imaging of Tracers based on superparamagnetic iron oxide nanoparticles (SPIONs) with high sensitivity, optimal patient handling and would even allow hybrid imaging of magnetic tracers within gold standard x-ray based interventional angiography systems. In initial experiments, the feasibility of a human-sized interventional MPI scanner with real-time data reconstruction and image visualization is demonstrated.

Space Syntax & Regression Analysis: Evaluating the Impacts of Urban form and Socio-Economic on Walkability in some of the Neighborhoods Dora, Baghdad.
Authors: Musaab Munqith Nasser  
Published: August 2023

Even though it has been found that walking around a neighborhood has many benefits, including health benefits, these factors must be taken into account when planning. Walkability is hard to measure and can't be boiled down to a single number because it depends on both the cultural and social aspects of a community. Using space syntax theory, the layout of streets in different kinds of communities was looked at, and regression analysis was used to measure the socioeconomic factor. This study looks at the syntactical properties of the city's organized and unorganized (agricultural) areas in relation to people's walking patterns; examines the socioeconomic characteristics of the population; and looks into people's walking patterns and the variables that influence walkability in the study area. By conducting observations of the areas and interviews with residents. Some of the results of the research are the variation and difference in the variables that affect both areas of the analysis or field observation. The findings are then used to recommend approaches that planners, designers, and decision-makers could take to create transit- and pedestrian-oriented developments.
Cibercondría en la educación médica
Authors: García-Estañ López Joaquín 
Published: August 2023

Cyberchondria is a term used to describe the excessive worry and anxiety a person experiences due to medical information they find online. This term refers to the tendency of some people to search for information about their symptoms or health concerns on the internet and then misinterpret that information to conclude that they have a serious or dangerous illness, even when that is not necessarily true. Cyberchondriacs can spend hours browsing medical websites, discussion forums, and other online resources, looking for information about symptoms or illnesses they think they have. This constant search for information can lead to increased anxiety and fear about one's own health, which in turn can lead to avoidance behaviors, such as avoiding leaving the house or constantly seeking medical attention. It's important to note that while online medical information can be helpful, it can also be incorrect, incomplete, or based on assumptions and speculation. In addition, the excess of medical information (infodemic) can create unnecessary anxiety and stress and can make it difficult to make informed decisions about health.
La cibercondría es un término utilizado para describir la preocupación excesiva y la ansiedad que una persona experimenta debido a la información médica que encuentra en línea. Este término se refiere a la tendencia de algunas personas a buscar información sobre sus síntomas o preocupaciones de salud en internet y luego interpretar erróneamente esa información para llegar a la conclusión de que padecen una enfermedad grave o peligrosa, incluso cuando eso no es necesariamente cierto. Los cibercondríacos pueden pasar horas navegando por sitios web médicos, foros de discusión y otros recursos en línea, en busca de información sobre síntomas o enfermedades que creen tener. Esta búsqueda constante de información puede generar un aumento en la ansiedad y el miedo sobre la propia salud, lo que a su vez puede llevar a conductas evitativas, como evitar salir de casa o buscar constantemente atención médica. Es importante tener en cuenta que, si bien la información médica en línea puede ser útil, también puede ser incorrecta, incompleta o estar basada en suposiciones y especulaciones. Además, el exceso de información médica (infodemia) puede generar ansiedad y estrés innecesarios y puede dificultar la toma de decisiones informadas sobre la salud.

ABSTRACT
TITLE: Perceived Clinical Readiness of Senior Medical Students as Outcomes 0f Online Clerkship in the Philippines: New Normal in Medical Education
INTRODUCTION: COVID-19 formed new challenges to the medical institutions; it resulted in the transition from the usual face-to-face classes and direct clerkship training within the hospital to a new remote learning with online lectures and virtual clinical experience. Given the new online interactive setting, problems were raised given the limited patient care and interaction as well as restricted bedside teaching opportunities and its impact on how medical students can acquire and hone their clinical skills.
OBJECTIVE: To determine the perceived clinical readiness of the medical clerks in the new normal setting in the Philippines.
METHODOLOGY: Convenience sampling was used to gather respondents who were asked to answer an online survey questionnaire. The questions pertained to: academic training profile, clinical skills, patient management, communication, understanding clinical guidelines, and personal development. After analyzing the data, the scales of readiness from these subjects were gathered.
RESULTS: The medical clerks in the Philippines perceived that they were ready with regards to understanding clinical guidelines, communication, personal development, and patient management. They were moderately ready in the different clinical skills in the departments of Family and Community Medicine, Internal Medicine, Pediatrics, Surgery and Obstetrics and Gynecology with some specific skills in Surgery and Obstetrics and Gynecology being perceived as less ready than the rest.
CONCLUSION: The impact of the pandemic has disrupted the student’s confidence and readiness. This shows that online clerkship in this time of pandemic may have provided learning to a certain degree but it is not enough to replace what face-to-face training could offer.
Uncovering the Grinnellian niche space of the cryptic species complex Gammarus roeselii
Authors: Kabus Jana , Cunze Sarah , Dombrowski Andrea , Karaouzas Ioannis , Shumka Spase , Jourdan Jonas 
Published: August 2023

Background
The discovery of cryptic species complexes within morphologically established species comes with challenges in the classification and handling of these species. We hardly know to what extent species within a species complex differ ecologically. Such knowledge is essential to assess the vulnerability of individual genetic lineages in the face of global change. The abiotic conditions, i.e., the Grinnellian niche that a genetic lineage colonizes, provides insights into how diverse the ecological requirements of each evolutionary lineage are within a species complex.

Material and Methods
We sampled the cryptic species complex of the amphipod Gammarus roeselii from Central Germany to Greece and identified genetic lineages based on cytochrome c oxidase subunit I (COI) barcoding. At the same time, we recorded various abiotic parameters and local pollution parameters using a series of in vitro assays to then characterize the Grinnellian niches of the morphospecies (i.e., Gammarus roeselii sensu lato) as well as each genetic lineage. Local pollution can be a significant factor explaining current and future distributions in times of increasing production and release of chemicals into surface waters.

Results
We identified five spatially structured genetic lineages in our dataset that differed to varying degrees in their Grinnellian niche. In some cases, the niches were very similar despite the geographical separation of lineages, supporting the hypothesis of niche conservatism while being allopatrically separated. In other cases, we found a small niche that was clearly different from those of other genetic lineages.

Conclusion
The variable niches and overlaps of different dimensions make the G. roeselii species complex a promising model system to further study ecological, phenotypic and functional differentiation within this species complex. In general, our results show that the Grinnellian niches of genetically distinct molecular operational taxonomic units (MOTUs) within a cryptic species complex can differ significantly between each other, calling for closer inspection of cryptic species in a conservational and biodiversity context.

Published: August 2023

A field experiment was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bengaluru, Karnataka to study the influence of different approaches of fertilizer application using soluble and conventional fertilizers on yield, nutrient requirement and economics of cabbage under drip fertigation. The results revealed that significant higher marketable cabbage yield of 62.55 t ha-1 was recorded in LMH approach followed by STCR inorganic approach (62.03 t ha-1) using soluble fertilizers and STCR integrated plant nutrition approach (61.31 t ha-1) using soluble fertilizers. Similarly higher nutrient uptake (N, P2O5 and K2O kg ha-1) was recorded in LMH approach followed by STCR inorganic approach using soluble fertilizers and STCR integrated plant nutrition approach using soluble fertilizers. However, nutrient requirement (NR) of N, P2O5 and K2O was highest in absolute control followed by LMH approach. Value cost ratio (VCR) worked out was found to be higher (13.37) in STCR inorganic approach using conventional fertilizers followed by STCR integrated approach using conventional fertilizers.

Published: August 2023

ImportanceColorectal cancer (CRC) is uncommon in adults younger than 50 years of age, so this population may experience delays to treatment that contribute to advanced stage and poor survival.ObjectiveTo investigate whether there is an association between time from presentation to treatment and survival in younger adults with CRC.Design, Setting, and ParticipantsThis retrospective cohort study used linked population-based data in Ontario, Canada. Participants included patients with CRC aged younger than 50 years who were diagnosed in Ontario between 2007 and 2018. Analysis was performed between December 2019 and December 2022.ExposureAdministrative and billing codes were used to identify the number of days between the date of first presentation and treatment initiation (overall interval).Main Outcomes and MeasuresThe associations between increasing overall interval, overall survival (OS), and cause-specific survival (CSS) were explored with restricted cubic spline regression. Multivariable Cox proportional hazards models were also fit for OS and CSS, adjusted for confounders. Analyses were repeated in a subset of patients with lower urgency, defined as those who did not present emergently, did not have metastatic disease, did not have cross-sectional imaging or endoscopy within 14 days of first presentation, and had an overall interval of at least 28 days duration.ResultsAmong 5026 patients included, the median (IQR) age was 44.0 years (40.0-47.0 years); 2412 (48.0%) were female; 1266 (25.2%) had metastatic disease and 1570 (31.2%) had rectal cancer. The lower-urgency subset consisted of 2548 patients. The median (IQR) overall interval was 108 days (55-214 days) (15.4 weeks [7.9-30.6 weeks]). Patients with metastatic CRC had shorter median (IQR) overall intervals (83 days [39-183 days]) compared with those with less advanced disease. Five-year overall survival was 69.8% (95% CI, 68.4%-71.1%). Spline regression showed younger patients with shorter overall intervals (&amp;lt;108 days) had worse OS and CSS with no significant adverse outcomes of longer overall intervals. In adjusted Cox models, overall intervals longer than 18 weeks were not associated with significantly worse OS or CSS compared with those waiting 12 to 18 weeks (OS: HR, 0.83 [95% CI, 0.67-1.03]; CSS: HR, 0.90 [95% CI, 0.69-1.18]). Results were similar in the subset of lower-urgency patients, and when stratified by stage.Conclusions and relevanceIn this cohort study of 5026 patients with CRC aged younger than 50 years of age in Ontario, time from presentation to treatment was not associated with advanced disease or poor survival. These results suggest that targeting postpresentation intervals may not translate to improved outcomes on a population level.
