Considerations in Acquisition of 3D-Printed Art

ABSTRACT 3D printing (also known as Rapid Prototyping or Additive Manufacture) is increasingly common and technically sophisticated, and is utilized in art and design, industry, and consumer applications. Museums and collectors are now acquiring works made using this technology though their preservation needs are not fully understood. This article provides an overview of the technology and related terminology, review of related conservation literature, and introduction to current efforts for the care of these works. Discussion includes the formulation of collaborative working practices, documentation during acquisition, and consideration of periodic reprinting. Case studies include a pre-accession checklist developed at SFMOMA (San Francisco Museum of Modern Art) and the reprinting of select components from Altar/Engine (2015) by Tauba Auerbach at MoMA (Museum of Modern Art) in New York. Though 3D-printed works may be found in science, history, and other collections, this study will focus on works of contemporary art and design.

Unexplained cardiac arrest (idiopathic ventricular fibrillation): clinical and genetic characteristics

AIM: The study was to evaluate the clinical and genetic characteristics of inherited arrhythmias in patients who survived unexplained cardiac arrest. MATERIALS AND METHODS: 20 patients (10 male and 10 female) aged 15 to 55 years (median age 36 [28; 44] years) with documented VT/VF on ECG were observed for 3 years. The clinical and instrumental study included registration of 12-lead ECG, 24-hour Holter ECG, genealogical history collection and family history of sudden cardiac death with ECG assessment of all family members, transthoracic echocardiography, 2D Speckle Tracking echocardiography and cardiac magnetic resonance imaging to exclude structural myocardial changes. High-throughput sequencing (NGS) was utilized to search for mutations in genes linked to the onset of channelopathies and other inherited rhythm disorders. RESULTS: In 4 (20 %) of the 20 probands included in the study, likely pathogenic variants were identified (pathogenicity class IV), and in 7 (35 %) patients, variants with unknown clinical significance (pathogenicity class III) in 10 genes associated with channelopathies (KCNQ1, KCNH2, SCN5A, AKAP9, ANK2, SCN10А, RYR2) and cardiomyopathies (MYH7, JPH2, RBM20). Several genetic variants were found in 3 cases. No significant genetic changes were detected in 9 (45 %) probands. The clinical diagnosis was established during the follow-up period and was verified due to the genetic testing in 5 (25 %) patients. From their ECGs, a prolonged QTc 460 ms was found in 1 patient, Brugada pattern in 2 individuals, and a shortening of QTc up to 323 ms in 1 proband. Subclinical structural changes associated with cardiomyopathies were revealed in 2 patients. In 15 (75 %) patients, it was unfeasible to establish a distinct clinical phenotype. In 6 (30 %) probands, the diagnosis was clarified due to detected genetic variants. CONCLUSION: Clinical manifestations and diverse genetic variants have been studied in patients who have survived unexplained cardiac arrest. In the course of genotyping patients who suffered unexplained cardiac arrest, genetic changes associated with LQTS were detected in 30 % of cases, while the QTc in most cases did not exceed 440 ms, which makes it difficult to establish a diagnosis at an early stage before the development of life-threatening arrhythmic events. The data from our study confirm the idea that in patients with idiopathic ventricular fibrillation, who have suffered unexplained cardiac arrest, cardiac channelopathy or subclinical manifestations of cardiomyopathy are commonly the cause. This phenomenon imposes a need for genetic testing in this category of patients.

Ensemble automated approaches for producing high‐quality herbarium digital records

AbstractPremiseOne of the slowest steps in digitizing natural history collections is converting labels associated with specimens into a digital data record usable for collections management and research. Here, we address how herbarium specimen labels can be converted into digital data records via extraction into standardized Darwin Core fields.MethodsWe first showcase the development of a rule‐based approach and compare outcomes with a large language model–based approach, in particular ChatGPT4. We next quantified omission and commission error rates across target fields for a set of labels transcribed using optical character recognition (OCR) for both approaches. For example, we find that ChatGPT4 often creates field names that are not Darwin Core compliant while rule‐based approaches often have high commission error rates.ResultsOur results suggest that these approaches each have different strengths and limitations. We therefore developed an ensemble approach that leverages the strengths of each individual method and documented that ensembling strongly reduced overall information extraction errors.DiscussionThis work shows that an ensemble approach has particular value for creating high‐quality digital data records, even for complicated label content. While human validation is still needed to ensure the best possible quality, automated approaches can speed digitization of herbarium specimen labels and are likely to be broadly usable for all natural history collection types.

Barriers to Family History Collection and Family Medical Screening Recommendation in the Sudden Death in the Young Case Registry.

Sudden death in the young (SDY) poses a public health problem affecting thousands of individuals annually in the United States. The SDY Case Registry utilizes existing infrastructure of death investigation programs, including medical examiner/coroner (ME/C) systems, to enhance understanding of SDY causes and risk factors to inform prevention strategies. This includes identifying and promoting screening recommendations for at-risk family members. To explore barriers to family history collection and familial screening recommendation procedures across Registry sites, nine individuals from seven SDY sites were interviewed. Interviews focused on logistics, methods to address barriers, and recommendations for improvements. Despite variability in practices, data analysis revealed three common themes related to barriers of these processes: (1) timing and grief, (2) lack of family history in medical records, and (3) families lost to follow-up. This study offers insights into these processes within the Registry and sheds light on broader practices within the death investigation domain. Data analysis led to recommendations for the improvement of these practices including the prioritization of three key family history questions during the initial death investigation by a designated individual in each office/system.

Playing With the Past: Building an Aztec Paper Warrior Doll

Ritual, war, and tribute were three of the most important aspects of Aztec culture before they were conquered by the Spaniards in 1521. In this paper, I explore the significance behind tributary objects found in the Codex Mendoza by creating a paper Aztec warrior doll. The Codex Mendoza was a collection of 71 folios curated by the Spanish in 1542 that showcased Nahua culture and the Aztec tributary system. Using both the Codex Mendoza and a larger collection of Nahua history in the Florentine Codex, I contextualized my project in the rituals and history of Aztec culture pre-conquest. For my project, I created a fearsome animal helmet to showcase the fear factor used in ritual warrior costumes, emphasizing a feeling of movement seen in Nahua art by using a European volvelle to articulate the helmet's jaw. I further incorporated elements of indigenous “covering” found in illustrations of the Florentine Codex when considering the material of both the helmet and the cotton armor I recreated from the tributary items, using crumpled tissue paper to reflect the “chewed-up” style of paper covering idols of the warrior deity Huitzilopochtli. Referencing Aztec rituals was something I kept in mind throughout my project as I researched the significance of religious war objects like the temiotl (“god” or “sacred forelock”) and ihuiteteyo (design for war shield) on the dominant symbol of the shield. By analyzing Nahua rituals as seen in the Florentine Codex, I was able to explore the significance behind tributary warrior items in the Codex Mendoza and illuminate just how important materiality and ritual were to Aztec warriors. 

Voices from La Frontera

Established in 1972, the University of Texas at El Paso (UTEP) Institute of Oral History (IOH) holds the largest collection of border-related oral histories in the United States. Containing interviews dating back to the 1960s, the collection is particularly strong with themes related to labor, immigration, the Bracero Program, and the Mexican Revolution. This article explores the history of the U.S. Border Patrol as gleaned from UTEP oral histories. El Paso and the Border Patrol have a very long and complicated history. The first officers were stationed in El Paso and the first training academy was there. Today, the presence of the Border Patrol is ubiquitous. Using the collection, we investigate what oral histories can tell us that official government documents cannot. How did Border Patrol officers feel about their work and about the people they encountered trying to enter the United States? How did the day-to-day work of Border Patrol officers change over time while the mission of the agency “to detect and prevent the illegal entry of individuals into the United States” remained the same? The article also sheds light on the response of migrants and immigration advocates to the work of the Border Patrol.

Individuation of a cut-off value of triglyceride-glucose index for incident diabetes mellitus in patients with essential hypertension.

The prevalence of obesity and diabetes, risk factors for atherosclerotic vascular diseases, is increasing worldwide; therefore, it is desirable to early identify them to reduce cardiovascular events. Thus, we investigated whether the triglyceride-glucose index (TyG index), a new marker of insulin resistance, is associated with incident diabetes in patients with newly diagnosed arterial hypertension. We selected 585 patients with newly diagnosed arterial hypertension referred to our tertiary Clinic of Catanzaro University Hospital for the evaluation of their cardiometabolic risk profile. None of the patients had diabetes mellitus at enrollment and took any drug known to affect glucose metabolism. Patients underwent medical history collection, clinical examination and laboratory tests. The TyG index was calculated as the ln [fasting TG (mg/dl) × FPG (mg/dl)/2], as previously suggested. During the follow-up [mean 8.5years (range 3.1-10.7)], there were 78 new cases of incident diabetes (1.57% patient-year). Patients who developed diabetes mellitus were older and had a higher body mass index (BMI), baseline blood pressure, fasting glucose, insulin, homeostatis model sssessment (HOMA) index, triglyceride, creatinine and hs-CRP mean values, while estimated glomerular filtration rate values were lower. At the Cox regression analysis, covariates significantly associated with incident diabetes were: BMI (HR = 2.842, 95%CI = 2.299-3.514), TyG index (HR = 2.392, 95%CI = 1.745-3.192), age (HR = 1.944, 95%CI = 1.527-2.474), hs-CRP (HR = 1.409, 95%CI = 1.153-1.722), and HOMA (HR = 1.325, 95%CI = 1,079-1.756). The best estimated cut-off value of TyG index in predicting diabetes was 4.71. In addition, we documented a significant relationship between TyG index and HOMA (r = 0.575; p < 0.0001). Present data demonstrate that TyG index, a simple and cost-effective marker of insulin resistance, is useful in predicting incident diabetes in patients with arterial hypertension.

Identifying design features within a historic costume collection to inspire contemporary inclusively designed adaptive apparel in a product development course

ABSTRACT This study investigated the potential of inclusively designed adaptive apparel discovered within a historic costume and textile collection to inspire contemporary inclusive and adaptive apparel design in a product development course. This study employed object-based learning as the theoretical framework, focusing on the tangible examination and analysis of historical garments as educational tools. A descriptive analysis qualitative methodology was used to identify the key inclusive adaptive apparel design features that could potentially inform inclusively designed adaptive apparel in the present day. By examining a diverse range of historical garments, this study aimed to uncover design elements that transcend time and cultural contexts, providing valuable insights for contemporary product development students seeking to create inclusively designed adaptive apparel collections. The findings from this study suggest that historic costume and textile collections are a compatible and significant source for integrating inclusive design features into the apparel design classroom.

Two cnidian plastic vessels of the 2nd century ad from the collection of the state historical museum: technological research

The article considers two textbook-famous Cnidian plastic vessels from the collection of the State Historical Museum in Moscow. One of them, shaped as a ram, comes from the excavations of N.I. Veselovsky in the Kuban region, the second one – a lagynos with erotic scenes on its body – was found by I.I. Gushchina at the Late Scythian burial ground Belbek IV in the Southwestern Crimea. As part of a project to do research on monuments of the classical period from the State Historical Museum collection, an X-ray tomographic study of these vessels was conducted at the National Research Centre “Kurchatov Institute”, which made it possible to clarify the technology of their manufacture.

Reclaiming and Unlocking Ancient Heritage Knowledge from Ethiopia’s Ancient Cultural Heritages

Abstract The purpose of this paper is to reclaim and unlock heritage knowledge related to the secular value of time and labor from a sample Ethiopian ancient Ge’ez parchment manuscript. We claim that Ethiopia’s ancient Ge’ez parchment manuscripts could be a source of heritage knowledge if systematically studied. We conducted an extensive and intensive survey to identify and select relevant ancient Ge’ez parchment manuscripts from ancient churches and monasteries in Tigray, Ethiopia. We selected one Ge’ez parchment manuscript for content analysis related to secular value time and another Ge’ez parchment manuscript for the secular value of labor and work ethics. Content analysis and interpretation including language translation from Ge’ez to Tigrinya and English was used as a method of heritage knowledge extraction, as were unlocking approaches from the selected sample Ge’ez parchment manuscripts. Digital content was also produced in order to have access to the digital content, which facilitates further content analysis. A critical evaluation of the physical condition of the sample manuscripts including their palaeography, folios, marginalia, and provenance was made in order to establish their relative age and credibility. From our content analysis, we extract and unlock valuable information and heritage knowledge domains related to the secular value of time and labor. The striking aspect in this study is that the sources of such heritage knowledge are the ancient Ge’ez manuscripts preserved for centuries in religious institutions like ancient churches and monasteries. These sources of heritage knowledge could be easily accepted by Christian farmers to address and solve their earthly problems. We, therefore, assert that the analysis of manuscripts democratizes access to knowledge, making historical collections accessible to a broader audience. Therefore, this current research paper extends the scope of previous studies from merely identifying preservation challenges and making ancient manuscripts accessible through digitization to conducting content analysis, unlocking relevant heritage knowledge domains, and disseminating the knowledge as well as preventing the loss of valuable heritage knowledge. Finally, we suggest making a paradigm shift from preserving heritage for its own sake to focusing on heritage knowledge transfer and education. This is mainly because we currently stand at a crossroads, facing a dilemma between valuing and utilizing heritage on one hand and ensuring its sustainable preservation on the other.

The potential use of immersive virtual environments for collecting and archiving heritage gameplay activities in digital libraries

Purpose This paper aims to discuss and propose the potential use of immersive virtual environments (IVEs) for archiving and collecting heritage gameplay activities in digital libraries, which is expected to triangulate further discussions on the said knowledge scopes. Design/methodology/approach The key question of this paper is, how we can preserve and revitalize fading heritage game activities in digital libraries? To answer this, the paper is going to understand the applications of IVEs in heritage studies; the use of telepresence experiences in IVEs for activity-based collection; the creation of virtual and telepresence experiences in digital libraries; and a proposed use of IVEs for archiving heritage gameplay activities. Findings The applications of IVEs and/or other virtual technologies have certainly been gaining positive feedback about their ability to provide vivid images of artefacts and art pieces; perform a high level of interactivity between the exhibits and visitors; enhance visitors’ sense of immersion that evoke their memories of heritage issues; facilitate visitors’ learning process in libraries; increase enjoyment in digital libraries. As mentioned in the previous section, the activity-based historical collection, for instance, the heritage gameplay activities, can be preserved and archived vividly using IVEs. Research limitations/implications This paper is explorative, there is no empirical result for generalization. Originality/value This paper aims to provide librarians with valuable insight to apply IVEs for archiving and collecting heritage gameplay activities. Setting up a new type of digital library is affected greatly by the openness of librarians, visitors’ expectations and a whole lot of things that are happening around the technological world and digital culture. This paper addresses the applications of IVEs in heritage studies, the importance of creating virtual and telepresence experiences for library visits as well as proposing the use of IVEs for archiving heritage gameplay activities.

Building New Opportunities: Planning Towards Integrated, Open and Accessible Natural History Collections

The accessibility, value and role of natural history collections (NHCs) for nature conservation, education and society in general, increases over time. The concept of NHCs evolves through advancements in information systems, research methods, and collection studies (Miller et al. 2020). Therefore, we need a new infrastructure for NHCs, which provides the necessary physical and organizational structures to support this evolving approach, including digitization labs, digital solutions for improved workflows, and architectural designs like publicly viewable collection workplaces. With this concept, the contemporary museum constitutes a shared space that recognises the importance of nature, supported by a science-based approach. The Estonian Museum of Natural History (EMNH) is currently making one of the largest developmental leaps in its 160-year history. In total, approximately 360,000 specimens, dating back 200 years, are preserved in the museum’s storage facilities. The museum’s collection contains specimens from around the world and is focused on Estonia’s natural heritage. The collection includes extensive mycological, zoological, botanical, geological, and science-related historical artifacts (e.g., collecting equipment, models of specimens), along with photo and multimedia collections. Currently, 95% of the museum's collections are digitized. The specimen data is published in the Global Biodiversity Information Facility (GBIF), with the original data housed on the PlutoF and Geocollections platforms. Although the museum plays a significant role in advancing the natural sciences, people outside the museum's circle might find it difficult to perceive how vast and unique the collections are, and what kind of work is done behind the scenes. The role of collections in science, education or society in general is also only vaguely acknowledged. By constructing a new building for the EMNH, scheduled to open in 2027, new opportunities arise. As a new community centre, the museum provides the opportunity for visitors, emerging professionals, citizen scientists, students, etc. to enhance and share their knowledge of the importance of biodiversity. Some examples of the numerical growth the new building will bring, compared to old museum facilities, are as follows: the museum could attract 200 000 more visitors than we are able to welcome in the current building. The new building will have ten times more exhibition space and the collection area will enlarge more than 50% from its current size. Many infrastructural and conceptual ideas applied in the new building will contribute to integrating our NHCs into society. Extra workspace will provide sufficient room for curators and students, researchers, and interns. New curator workrooms contain flexible spaces for different projects. The exhibition hall features display windows allowing visitors to peek into the curator’s workrooms, collection spaces, and the wet preparations lab. By embracing the principle of an open collection, the museum offers a unique opportunity to observe how specimens are stored and what procedures are involved in their preservation. This way the usually hidden part of the museum is integrated to the exhibition. A special room is planned for a mixed collection, comprised of a variety of differently prepared specimens and a display of various storage methods. The room will be primarily used to welcome groups and provide educational visits. For hands-on education, the new building will house a learning laboratory, classrooms and a space with direct access from the street for workshops, meetings, and experimental exhibitions, making it easier to engage passers-by. The exhibition area will have a multifunctional activity space within the exhibition, where museum staff can showcase various sections of their work. The digitization lab provides the opportunity to create high-quality photos and digital twins of specimens (Reinhardt et al. 2024), making them more accessible among scientists and the wider public. Improved digital imaging quality enhances research possibilities for photo analysis and AI applications. The new workshop also provides an excellent opportunity for conservation and taxidermy of specimens. We engaged target groups from school children to specialists during the planning process to make a museum that fulfills their needs. The new museum is planned as a platform that engages the society, initiates discussions, and brings together various target and interest groups to discuss environmental topics. By planning and building new infrastructure for the EMNH, we develop both digital and physical functionality and make our NHCs more accessible to all interest groups. The concept of open collections brings the behind-the-scenes activities to everyday visitors, engages people, and informs them about the opportunities and the role of NHCs. The new core exhibition and the science-based environmental-educational activities tightly linked to our NHCs will create a new incubator for positive changes. By developing and introducing new methods of making our NHCs accessible to a wider audience, the collections can better assist the society in making decisions and raising awareness.

Unifying Community Efforts on Registration and Data Rights

At the Smithsonian National Museum of Natural History (SI NMNH), the Assistant Registrar and Informatics Manager in the Department of Paleobiology (Paleo) have identified key linkages between registering collections (documentation for specimens and data through acquisitions, loans and disposals) and management of digitized collections, especially for usage right designation. Both roles require extensive collaboration on a shared framework for managing data related to the provenance of fossil specimens and rights associated with any derivative digital assets. This eliminated a disconnect in overlapping responsibilities: those typically siloed in museum registration practices (e.g., provenance data, intellectual property rights) and the data typically siloed in collections management and digitization workflows (e.g., data quality, digital asset management, and usage rights). Paleo shifted to a new practical approach and mindset focused on communal thinking. This propelled implementation of data standard practices and laid the building blocks for a shared community perspective on digitizing paleontological collections. Since 2020, Paleo established processing workflows for digital asset requests of the fossil collections (new digital asset creations vs. use of existing digital assets) and baseline understandings about rights of digital assets. These products led to a comprehensive effort to outline SI NMNH’s options to designate usage rights for digital assets (Table 1) and distribute basic understandings about Smithsonian Terms of Use and Smithsonian Open Access Policy (SI OA) across SI NMNH. Paleo explored this topic further by engaging in virtual meetings, conferences, presentations and informal discussions with the collections management staff and data managers across SI NMNH and externally with domestic and international groups such as the Paleo Data Working Group (PDWG), Society for the Preservation of Natural History Collections (SPNHC) Registrars Group, and Biodiversity Information Standards (TDWG), to develop data standards initiatives for loans, permits and sensitive data (Fig. 1). Through regular community engagement, Paleo forged a concise, yet evolving, perspective on digitizing collections, which aligned both registration and informatics data management needs within the department and museum (Fig. 2). This multi-professional perspective enables the promotion of shared community knowledge and understanding about data rights. The primary purpose is to balance consistent goals, current needs, and long-term outcomes with the flexibility to adapt our practices based on institution-specific policies, new research methods, and varying domestic and international regulations and laws. The notable outcomes from almost four years of work are highlighted and incorporated into Paleo's departmental policy and documentation requirements for processing and fulfilling digital asset creation or use requests workflows and distribution of this information to the public website for visitors and borrowers. However, there are still persisting challenges related to registering and managing these digital assets. There are immediate and future obstacles such as: limitations in effective tracking methods to record creation of digital assets, use of digital assets, and designation of what usage rights and when the decision was made; gaps in community practice, policy and regulations at the institutional level and globally; past practices in workflows and staff structures or lack thereof, which have left digital assets in limbo without means of accessing the data or documentation to identify the appropriate use options and rights. We see a need to continue asking questions. How are varying policies across institutions globally, impacting compliance concerns in registration for sharing sensitive information with other research institutions? How have or will new research techniques and opportunities impact the need for flexibility in practices and decisions? Are there alternative ways to utilize a Collections Management Systems (CMS) or use other platforms to track, store and manage the digital assets? How have others engaged in community discussions to address overlapping needs for data standards and registration of digitized collections? These identify significant inconsistencies across the community that need further discussion with subject-matter experts before effective and comprehensive decisions in data standards for managing digitized collections can be made. Ultimately, there are outstanding questions and challenges at all stages for registering, digitizing and managing digital assets of natural history collections. We continue to unveil nuances in thinking about this topic and find the need for structures of shared knowledge built and actively engaged in by a professionally diverse community. The utilization of subject-matter experts encourages collaboration and alternative perspectives to standardize operations and policy while expanding community efforts and awareness.

A Snakemake Toolkit for the Batch Assembly, Annotationand Phylogenetic Analysis of Mitochondrial Genomes and Ribosomal Genes From Genome Skims of Museum Collections.

Low coverage 'genome-skims' are often used to assemble organelle genomes and ribosomal gene sequences for cost-effective phylogenetic and barcoding studies. Natural history collections hold invaluable biological information, yet poor preservation resulting in degraded DNA often hinders polymerase chain reaction-based analyses. However, it is possible to generate libraries and sequence the short fragments typical of degraded DNA to generate genome-skims from museum collections. Here we introduce a snakemake toolkit comprised of three pipelines skim2mito, skim2rrna and gene2phylo, designed to unlock the genomic potential of historical museum specimens using genome skimming. Specifically, skim2mito and skim2rrna perform the batch assembly, annotation and phylogenetic analysis of mitochondrial genomes and nuclear ribosomal genes, respectively, from low-coverage genome skims. The third pipeline gene2phylo takes a set of gene alignments and performs phylogenetic analysis of individual genes, partitioned analysis of concatenated alignments and a phylogenetic analysis based on gene trees. We benchmark our pipelines with simulated data, followed by testing with a novel genome skimming dataset from both recent and historical solariellid gastropod samples. We show that the toolkit can recover mitochondrial and ribosomal genes from poorly preserved museum specimens of the gastropod family Solariellidae, and the phylogenetic analysis is consistent with our current understanding of taxonomic relationships. The generation of bioinformatic pipelines that facilitate processing large quantities of sequence data from the vast repository of specimens held in natural history museum collections will greatly aid species discovery and exploration of biodiversity over time, ultimately aiding conservation efforts in the face of a changing planet.

Predictors of Right vEntricular Failure aftER LVAD implantation: PREFER LVAD study

Abstract Introduction The use of left ventricular assist devices (LVAD) is increasing both as bridge-to-transplantation or destination therapy, considering the lack of heart donors for transplantation in advanced heart failure (AHF) population. Right ventricular post-implantation failure, major bleedings and infective events remain the principal adverse events in LVAD carriers, thus an accurate selection of candidates is needed. Purpose To identify between clinical, laboratory, standard and advanced (Speckle Tracking, STE) echocardiography, and right heart catheterization (RHC) indices, the best predictors of outcome after LVAD implantation. Materials and Methods We screened in our third-level center 30 patients with AHF, followed up from May 2013 to February 2022, for the assessment of LVAD implantation suitability. They all underwent a complete cardiological history collection, electrocardiography, standard and STE left ventricular (LV) and left atrial (LA) size and function assessment. Regarding the right ventricle, SIENA score parameters, including RV sphericity index, RV free wall longitudinal strain (LS), right ventricular fractional area change (RVFAC), and 3D ejection fraction were used for exclude RV disfunction. RHC was performed on the same day of echocardiography. Follow-up was conducted at 1, 3, 6, 9 and 12 months repeating all the assessments, for the occurrence of RV failure, all-causes mortality, hemorrhagic events and re-hospitalization for heart failure. With a univariate and multivariate statistical analysis, we went to test among all the parameters the possible predictors of outcome. Results The final population consists of 29 patients (93% male, mean age of 63±11 years), in NYHA class III or IV and a severe reduction of left ventricular (LV) ejection fraction (EF), in whom arterial hypertension and smoking, present or previous, were present in 58% and 65% of cases, respectively. The population was divided into two groups according to the occurrence of at least one cardiovascular event. 11 major events were recorded: including 4 hemorrhagic events, 3 all-causes mortality and 4 hospital admission for HF. No RV failure occurred in the first 12 months of follow-up. No differences were identified between the two groups in terms of echocardiographic indices and RV function, including RVFAC or RV-FWLS. At univariate analysis (see Table 1), the only parameter able to predict major CV events was central venous pressure (CVP)/pulmonary capillary wedge pressure (PCWP) ratio, obtained by RHC, an index of balance between right and left heart filling pressure. Conclusions A careful application of SIENA score indices before LVAD implantation can significantly reduce the incidence of post-operative RV failure, as in our small population. Our results also confirmed the paramount role of RHC in the diagnostic work up of AHF.

Faster extraction of matrimonial advertisements from digital archives using a signal processing pipeline: a case study on a 20th-Century Spanish newspaper

ABSTRACT With the exponential growth of digitized historical materials, historians and social scientists face the daunting task of navigating vast online collections. While online archives do provide search tools to query their materials, these usually do not meet the scholars’ need to trace and store all relevant materials from the online archive. This case study shows how computer vision methods, and more specifically a signal processing approach, can be used to identify, classify and extract relevant information items from a vast historical data collection. More specifically, this study reports the results of the construction of a data pipeline that extracts matrimonial advertisements from the digitized Catalan newspaper La Vanguardia. Matrimonial advertisements can provide genuine insights into the evolution of partner preferences over time, but they are hard to collect as they are scattered over millions of digitized historical newspapers and magazines. Moreover, to study variation in partner preferences by, for example, sex, social class, matrimonial status and time period, it is necessary to store the data into a database. The pipeline that we have constructed extracts matrimonial advertisements in a stepwise fashion, encompassing identification, through binarisation and segmentation, and classification based on Optical Character Recognition. By ways of a comprehensive evaluation, both qualitatively and quantitatively, the efficacy of the pipeline for the extraction of matrimonial advertisements is demonstrated. The findings not only underscore the viability of the signal processing approach but also underscore its potential for advancing research in historical demography, family history, as well as economic history, as similar pipelines can be set up to extract other relevant newspaper items, such as, marriage, birth, death and moving announcements, job vacancies or business announcements from digitized source collections.

Comusichiamo. First Language, Life-Soundtracks and Storytelling to Support the Cultural Wellbeing of Migrants Living with Dementia

ABSTRACT This study, located at the intersection of anthropology, ageing, music therapy and dementia, explores the value of music, life-storytelling and first language, to support the cultural identity and wellbeing of people from culturally and linguistically diverse backgrounds living with dementia in Australia. It uses participant observation, the collection of oral histories and ‘life soundtracks’ to co-create a song with older Italian migrants and their families. This paper presents the first case study which informed the development of the music engagement program we call Comusichiamo (let’s make music together). The case study shows that the co-creation of a culturally tailored song, composed and sung in first language, can enhance physical and social engagement, and contribute to the general wellbeing of participants living with dementia, and their carers. Central to the program is the sharing of life history, comprising autobiographic memory, the use of ipsissima verba, the precise words participants employ repeatedly, and ipsissima fabula, the particularistic stories participants narrate frequently. This music engagement program supports a relationship-centred approach to dementia care, drawing on narrative theory and anthropological notions of personhood, and Benenzon’s notion of ‘sound identity’, to support cultural safety, protect personhood, and guard against ‘social death’.

A smartphone app for preschool wheezing and reliability of medical history collection

BackgroundThe use of mobile applications helps improving self-management in adolescents with asthma. However, no evidence is available for children with preschool wheezing. In addition, we have no data on the reliability of medical history collected at visits. The first aim was to assess the feasibility of a smartphone app in the management of preschool wheezing; secondly we aimed to evaluate the reliability of anamnestic data collected during face-to-face medical interviews.MethodsChildren with recurrent wheezing, age between 25 and 72 months, were randomly assigned to the intervention group, provided with a smartphone app for symptoms monitoring and asthma attack treatment, or to the control group, with a written action plan. At follow-up medical history was collected and the asthma control test and a clinical questionnaire were completed. App acceptability was also explored. Respiratory symptoms, medication and utilization of healthcare resources were collected. Plus, medical information obtained from the paper questionnaires was compared with data daily recorded by the app.ResultsWe enrolled 85 preschool children with recurrent wheezing: 43 assigned to the intervention and 42 to the control group. The average (SD) adherence to e-Diary compilation was 60 (15)%. The acceptance and usability of the intervention was favorable as 70% and 93% of participants in the intervention arm described the app as ‘’simple and intuitive’’ at Visit1 (after 3 months from enrollement) and Visit2 (3 months later than Visit1), respectively and 95% and 98% found it useful in symptoms management. There were no significant differences between the two groups in clinical outcomes. At Visit1, the cACT median score (IQR) was 23,5 (21–25) for the control group (42 patients) and 23 (21–24) for the intervention group (43 patients). At Visit2 (41 controls and 42 in the intervention group) it was 25 (24–25) and 24 (24–25), respectively. Secondary analysis of data from the intervention group showed higher incidence of daily symptoms recorded by the app in comparison with the paper questionnaire, suggesting that collection of retrospective medical history may not be completely reliable.ConclusionsThe smartphone app is usable and acceptable by families of preschool wheezers. Future controlled trial are needed to prove an impact on clinical outcomes or its efficacy in a telemedicine program. Finally a daily questionnaire could provide physicians with a more reliable clinical picture as reflected better daily asthma symptoms than the written retrospective questionnaire filled at clinical visit.

Mobilising Historical Botanical Data as Research

Abstract The ‘Vegetable Substances’ collection consists of 8,811 surviving botanical objects and a manuscript catalogue that contains over 12,700 handwritten descriptions of the contents of these boxes, according to the collector, Hans Sloane (1660–1752). This pre-Linnean collection forms part of the founding botanical collection of the Natural History Museum in London, and currently sits at the top of the Darwin Centre. The process of transforming this physical historical collection into something digital began over a decade ago and this focus piece reflects on this digital practice to date. It describes the different stages of creating a public-facing digital resource, and how this practice of mobilising data functions as research.
