Background The relationship between mitral valve prolapse (MVP) and sudden cardiac death (SCD) remains controversial. In this systematic review, we evaluate the relationship between isolated MVP and SCD to better define a potential high‐risk subtype. In addition, we determine whether premortem parameters could predict SCD in patients with MVP and the incidence of SCD in MVP. Methods and Results Electronic searches were conducted in PubMed and Embase for all English literature articles published between 1960 and 2018 regarding MVP and SCD or cardiac arrest. We also identified articles investigating predictors of ventricular arrhythmias or SCD and cohort studies reporting SCD outcomes in MVP. From 2180 citations, there were 79 articles describing 161 cases of MVP with SCD or cardiac arrest. The median age was 30 years and 69% of cases were female. Cardiac arrest occurred during situations of stress in 47% and was caused by ventricular fibrillation in 81%. Premature ventricular complexes on Holter monitoring (92%) were common. Most cases had bileaflet involvement (70%) with redundancy (99%) and nonsevere mitral regurgitation (83%). From 22 articles describing predictors for ventricular arrhythmias or SCD in MVP, leaflet redundancy was the only independent predictor of SCD. The incidence of SCD with MVP was estimated at 217 events per 100 000 person‐years. Conclusions Isolated MVP and SCD predominantly affects young females with redundant bileaflet prolapse, with cardiac arrest usually occurring as a result of ventricular arrhythmias. To better understand the complex relationship between MVP and SCD, standardized reporting of clinical, electrophysiological, and cardiac imaging parameters with longitudinal follow‐up is required.

Host-to-host transmission of a pathogen ensures its successful propagation and maintenance within a host population. A striking feature of disease transmission is the heterogeneity in host infectiousness. It has been proposed that within a host population, 20% of the infected hosts, termed super-shedders, are responsible for 80% of disease transmission. However, very little is known about the immune state of these super-shedders. In this study, we used the model organism Salmonella enterica serovar Typhimurium, an important cause of disease in humans and animal hosts, to study the immune state of super-shedders. Compared to moderate shedders, super-shedder mice had an active inflammatory response in both the gastrointestinal tract and the spleen but a dampened T(H)1 response specific to the secondary lymphoid organs. Spleens from super-shedder mice had higher numbers of neutrophils, and a dampened T cell response, characterized by higher levels of regulatory T cells (T(regs)), fewer T-bet(+) (T(H)1) T cells as well as blunted cytokine responsiveness. Administration of the cytokine granulocyte colony stimulating factor (G-CSF) and subsequent neutrophilia was sufficient to induce the super-shedder immune phenotype in moderate-shedder mice. Similar to super-shedders, these G-CSF-treated moderate-shedders had a dampened T(H)1 response with fewer T-bet(+) T cells and a loss of cytokine responsiveness. Additionally, G-CSF treatment inhibited IL-2-mediated TH1 expansion. Finally, depletion of neutrophils led to an increase in the number of T-bet(+) T(H)1 cells and restored their ability to respond to IL-2. Taken together, we demonstrate a novel role for neutrophils in blunting IL-2-mediated proliferation of the TH1 immune response in the spleens of mice that are colonized by high levels of S. Typhimurium in the gastrointestinal tract.

General Earth and Planetary Sciences ,General Environmental Science - Abstract
COVID-19 and global crises/events are driving governments to rethink their national manufacturing strategies. The drastic change of societal conditions has exposed our reliance on a constrained set of production practices. Furthermore, the future manufacturing landscape indicates - supply chain crises, trade agreements and natural disasters - a high level of volatility which requires a response that is far from being achieved.While these emergent challenges have called the efficacy of established practices into question, new manufacturing technologies, such as Additive Manufacturing (AM), present the capability to provide a solution. One proposal is agent-based brokering of AM which could be a method for tackling local, regional, national, and international production needs. However, to achieve the reality of brokered AM, it is imperative that the diversity of AM capability is considered. Diversity that existing homogeneous modelling of AM and manufacturing systems rarely consider or capture. This paper conceptualizes the reality of AM systems and elucidates parameters that are necessary for successful modelling and subsequent co-ordination. Having presented the required parameters the paper continues to discuss requisite levels of abstraction, suitable performance metrics and the role of humans in agent-based manufacturing systems.

Abstract BerryPortraits (Phenotyping of Ripening Traits) is open source Python-based image-analysis software that rapidly detects and segments berries and extracts morphometric data on fruit quality traits such as berry color, size, shape, and uniformity. Utilizing the YOLOv8 framework and community-developed, actively-maintained Python libraries such as OpenCV, BerryPortraits software was trained on 512 postharvest images (taken under controlled lighting conditions) of phenotypically diverse cranberry populations (Vaccinium macrocarpon Ait.) from the two largest public cranberry breeding programs in the U.S. The implementation of CIELAB, an intuitive and perceptually uniform color space, enables differentiation between berry color and berry brightness, which are confounded in classic RGB color channel measurements. Furthermore, computer vision enables precise and quantifiable color phenotyping, thus facilitating inclusion of researchers and data analysts with color vision deficiency. BerryPortraits is a phenotyping tool for researchers in plant breeding, plant genetics, horticulture, food science, plant physiology, plant pathology, and related fields. BerryPortraits has strong potential applications for other specialty crops such as blueberry, lingonberry, caneberry, grape, and more. As an open source phenotyping tool based on widely-used python libraries, BerryPortraits allows anyone to use, fork, modify, optimize, and embed this software into other tools or pipelines.

Biology (General) ,QH301-705.5 - Abstract
Abstract Marine microbes that have for eons been adapted to stable salinity regimes are confronted with sudden decreases in salinity in the Arctic Ocean. The episodic freshening is increasing due to climate change with melting multi-year sea-ice and glaciers, greater inflows from rivers, and increased precipitation. To investigate algal responses to lowered salinity, we analyzed the responses and acclimatation over 24 h in a non-model Arctic marine alga (pelagophyte CCMP2097) following transfer to realistic lower salinities. Using RNA-seq transcriptomics, here we show rapid differentially expressed genes related to stress oxidative responses, proteins involved in the photosystem and circadian clock, and those affecting lipids and inorganic ions. After 24 h the pelagophyte adjusted to the lower salinity seen in the overexpression of genes associated with freezing resistance, cold adaptation, and salt tolerance. Overall, a suite of ancient widespread pathways is recruited enabling the species to adjust to the stress of rapid salinity change.

Background: An internal thoracic artery graft to the left anterior descending artery is standard in coronary bypass surgery, but controversy exists on the best second conduit. The RAPCO trials (Radial Artery Patency and Clinical Outcomes) were designed to compare the long-term patency of the radial artery (RA) with that of the right internal thoracic artery (RITA) and the saphenous vein (SV). Methods: In RAPCO-RITA (the RITA versus RA arm of the RAPCO trial), 394 patients Results: In the RA versus RITA comparison, the estimated 10-year patency was 89% for RA versus 80% for free RITA (hazard ratio for graft failure, 0.45 [95% CI, 0.23–0.88]). Ten-year patient survival estimate was 90.9% in the RA arm versus 83.7% in the RITA arm (hazard ratio for mortality, 0.53 [95% CI, 0.30–0.95]). In the RA versus SV comparison, the estimated 10-year patency was 85% for the RA versus 71% for the SV (hazard ratio for graft failure, 0.40 [95% CI, 0.15–1.00]), and 10-year patient survival estimate was 72.6% for the RA group versus 65.2% for the SV group (hazard ratio for mortality, 0.76 [95% CI, 0.47–1.22]). Conclusions: The 10-year patency rate of the RA is significantly higher than that of the free RITA and better than that of the SV.

Diagnosing the cause of abdominal disease in goats can be challenging. Clinical history, physical investigation, and laboratory findings do not always allow definitive identification of intra-abdominal disease or the underlying cause. Multidetector CT (MDCT) has become more readily available and now often replaces or augments other abdominal imaging techniques. The objective of this retrospective, observational, descriptive study was to investigate the clinical utility of MDCT for evaluation of the abdomen in goats with suspected abdominal disease involving the urinary, gastrointestinal, reproductive tracts and abdominal wall. Medical records (1/2009-12/2017) were reviewed for all goats undergoing an abdominal MDCT. Signalment, clinical history, examination and MDCT findings and outcome were recorded and categorized by abdominal organ system and wall lesion. Clinical problems and MDCT findings were compared in the various abdominal categories. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic odds ratio (OR) were calculated for MDCT, using clinical examination findings as the reference standard. A total of 85 goats underwent an abdominal MDCT examination. The sensitivity of MDCT for detecting urinary, gastrointestinal, reproductive tract, and abdominal wall abnormalities in goats with clinical problems related to these body systems was high at 94.7 %, 78.3%, 94.1%, and 100%, and the specificity was high at 95.6%, 96.7%, 93.9%, and 100%, respectively. The PPV was 94.7%, 90.0 %, 80.0%, and 100.0%, the NPV was 95.6%, 92.1%, 98.4%, and 100%, and the OR were 387.0, 104.4, 248.0, and infinite. In conclusion, findings supported the use of MDCT as an adjunct diagnostic test for assessing goats with abdominal disease.

Allenyl esters activated by titanium(IV) underwent additions to a wide range of aldehydes in high regio- and diastereoselectivities leading to products containing an all-carbon quaternary center bearing an α-vinyl group that was installed with high selectivity for the Z-geometry. An aldol product was also converted to an indanone offering a new route to this important compound class. Product triple diastereoselectivity has been rationalized using a concerted transition-state model.

Measuring inflammatory markers is critical to evaluating both recent infection status and overall human and animal health; however, there are relatively few techniques that do not require specialized equipment or personnel for detecting inflammation among wildlife. Such techniques are useful in that they help determine individual and population-level inflammatory status without the infrastructure and reagents that many more-specific assays require. One such technique, known as the erythrocyte sedimentation rate (ESR), is a measure of how quickly erythrocytes (red blood cells) settle in serum, with a faster rate indicating a general, underlying inflammatory process is occurring. The technique is simple, inexpensive, and can be performed in the field without specialized equipment. We took advantage of a population of African buffalo (Syncerus caffer), well studied from June 2014 to May 2017, to understand the utility of ESR in an important wildlife species. When ESR was compared with other markers of immunity in African buffalo, it correlated to known measures of inflammation. We found that a faster ESR was significantly positively correlated with increased total globulin levels and significantly negatively correlated with increased red blood cell count and albumin levels. We then evaluated if ESR correlated to the incidence of five respiratory pathogens and infection with two tick-borne pathogens in African buffalo. Our results suggest that elevated ESR is associated with the incidence of bovine viral diarrhea virus infection, parainfluenza virus, and Mannheimia haemolytica infections as well as concurrent Anaplasma marginale and Anaplasma centrale coinfection. These findings suggest that ESR is a useful field test as an inflammatory marker in individuals and herds, helping us better monitor overall health status in wild populations.

Abstract Objectives We aimed to assess the attitudes and perceptions of scholarly activity (SA) practices among emergency medicine (EM) physicians who are engaged in training residents. This study examined the belief and need for modern‐day SA, potential barriers, and department resources provided. Methods We conducted a descriptive cross‐sectional survey study of EM physicians across the United States identified from the American College of Emergency Physicians and American College of Osteopathic Physicians directories. The survey consisted of 18 items regarding demographics, attitude toward SA, department support, and questions regarding residency programs. Results A total of 660 survey recipients completed the survey out of a possible pool of 4296 individuals (15% response rate), of which 530 (80%) indicated they were core faculty. Of core faculty, 428 (80.8%) were part of an allopathic program, whereas 102 (19.2%) were part of an osteopathic program. Department support was provided for protected time (385; 58.3%), research staff (346; 52.4%), Institutional Review Board preparation (240; 36.4%), and biostatistics (314; 47.6%). Of all the institutional roles, the largest percentage (82/125, 65.6%) of chair/vice chair/associate chairs strongly agreed or agreed (score of 5 or 4 of 5) with the statement, “Overall, I am satisfied with the scholarly support provided by my department.” There was no difference in agreement with this statement between respondents in an allopathic versus osteopathic program (210/428, 49.1% allopathic; 45/102, 44.1% osteopathic). Conclusion There is a need for increased departmental support for SA. To optimally implement the Accreditation Council for Graduate Medical Education (ACGME) SA requirements into strategy and action, the ACGME should consider providing EM residency programs with an outline of best SA practices to foster a uniform consensus across academic institutions.

IntroductionFor nearly two centuries, cranberry (Vaccinium macrocarpon Ait.) breeders have improved fruit quality and yield by selecting traits on fruiting stems, termed “reproductive uprights.” Crop improvement is accelerating rapidly in contemporary breeding programs due to modern genetic tools and high-throughput phenotyping methods, improving selection efficiency and accuracy.MethodsWe conducted genotypic evaluation on 29 primary traits encompassing fruit quality, yield, and chemical composition in two full-sib cranberry breeding populations—CNJ02 (n = 168) and CNJ04 (n = 67)—over 3 years. Genetic characterization was further performed on 11 secondary traits derived from these primary traits.ResultsFor CNJ02, 170 major quantitative trait loci (QTL; R2≥ 0.10) were found with interval mapping, 150 major QTL were found with model mapping, and 9 QTL were found to be stable across multiple years. In CNJ04, 69 major QTL were found with interval mapping, 81 major QTL were found with model mapping, and 4 QTL were found to be stable across multiple years. Meta-QTL represent stable genomic regions consistent across multiple years, populations, studies, or traits. Seven multi-trait meta-QTL were found in CNJ02, one in CNJ04, and one in the combined analysis of both populations. A total of 22 meta-QTL were identified in cross-study, cross-population analysis using digital traits for berry shape and size (8 meta-QTL), digital images for berry color (2 meta-QTL), and three-study cross-analysis (12 meta-QTL).DiscussionTogether, these meta-QTL anchor high-throughput fruit quality phenotyping techniques to traditional phenotyping methods, validating state-of-the-art methods in cranberry phenotyping that will improve breeding accuracy, efficiency, and genetic gain in this globally significant fruit crop.

The use of remote monitoring and virtual visits has accelerated to support socially-distanced patient care during the COVID-19 pandemic. Despite the necessity of this expansion, ambiguity in coding is hindering adoption and patient access, most notably for remote physiologic monitoring due to a lack of definition of the term “physiologic”. In this analysis, we describe the history of remote monitoring code development, present several examples in respiratory disease and other chronic conditions in which gaps and confusion remain and suggest ways to clarify and broaden coverage to ensure equitable access to remote monitoring.

As a pharmaceutical intervention, vaccines remain a major public health strategy for mitigating the effects of COVID-19. Yet, vaccine intake has been affected by various cognitive and cultural factors. We examine how a selected set of factors (i.e., knowledge, concern, media, peer influence, and demographics) shaped COVID-19 vaccination intention in the early phase of the pandemic (Fall 2020). Using a survey conducted in three US states (Idaho, Texas, and Vermont) just prior to the rollout of the first vaccines against COVID-19, we find that COVID-19 concern was the primary driver of vaccination intention. Concern was shaped mainly by two factors: political ideology and media sources. Yet, ideology and media were much more important in affecting concern for those who leaned politically conservative, as opposed to those who leaned liberal or remained moderate. The results from our structural equation models affirm that the information politically conservative respondents were receiving reinforced the effects of their ideology, leading to a greater reduction in their concern. We discuss the potential implications of these findings for future pandemic preparedness.

This paper argues for rethinking the economic geography of sharing and making in light of the recent proliferation of open innovation, makerspaces and maker movements. Using empirical research from an example of one such makerspace – Manchester’s FabLab – and engaging with a range of geographical literatures on making, sharing economies, and digital fabrication, we develop a critical account of sharing in principle and in practice. The portrayal of open innovation spaces, such as FabLabs, as novel makerspaces of alterity and sharing is a common and underpinning theme in both academic and marketing literature (Aldrich, 2014; Anderson, 2012; Doherty, 2012; Fab Foundation, 2012; Gershenfeld, 2005; Suire, 2019). However, our findings suggest that the values espoused by the FabLab, of involvement, connection and affinity, are quite literally being revised and rejected by makers who use the space. Time, labour and knowledge were for the most part described by participants as precious commodities to be savoured rather than shared. Thus, while sharing is an ordinarily economic practice, this does not mean it is always, inevitably or evenly employed by economic actors and communities, especially within counter-cultural networks. If these are to be the economies of the future, we implore economic geographers to critically engage further with the complexities of and within maker spaces.

The modern slavery literature engages with history in an extremely limited fashion. Our paper demonstrates to the utility of historical research to modern slavery researchers by explaining the rise and fall of the ethics-driven market category of “free-grown sugar” in nineteenth-century Britain. In the first decades of the century, the market category of “free-grown sugar” enabled consumers who were opposed to slavery to pay a premium for a more ethical product. After circa 1840, this market category disappeared, even though considerable quantities of slave-grown sugar continued to arrive into the UK. We explain the disappearance of the market category. Our paper contributes to the on-going debates about slavery in management by historicizing and thus problematizing the concept of “slavery”. The paper challenges those modern slavery scholars who argue that lack of consumer knowledge about product provenance is the main barrier to the elimination of slavery from today’s international supply chains. The historical research presented in this paper suggests that consumer indifference, rather than simply ignorance, may be the more fundamental problem. The paper challenges the optimistic historical metanarrative that pervades much of the research on ethical consumption. It highlights the fragility of ethics-driven market categories, offering lessons for researchers and practitioners seeking to tackle modern slavery.

The use of PD-1 immune checkpoint inhibitor medications has become a common practice in the treatment of recurrent and metastatic head and neck squamous-cell carcinomas. Success in this setting has led to the investigation of their efficacy in locally advanced cases as a part of first-line therapy. In this report, we detail the treatment response to palliative intent immunotherapy of three geriatric patients with mandibular gingival squamous-cell carcinoma who decided against surgical intervention. Patient #1 was treated with pembrolizumab, a PD-1 inhibitor, and displayed complete clinical and radiologic response of the gingival mass after three months of treatment, which is ongoing at 19 months from initiation. Patients #2 and 3 are each on treatment with single-agent pembrolizumab, with partial response of their tumors, minimal side effects, and ongoing response at 9 and 5 months of treatment, respectively. Durable clinical treatment response to palliative immunotherapy, as is evident in this report, warrants further consideration and investigation in the geriatric population. With appropriate patient selection, surgery may be avoided and allow patients to prioritize quality of life over curative intent surgery.

BACKGROUND Maternal cardiac disease is the most common cause of indirect maternal death, and women with pre-existing cardiac disease have complex medical, obstetric and anaesthetic requirements. Our hospital commenced a multidisciplinary perinatal cardiac service in 2009 to optimise outcomes in women with cardiac disease. AIM To assess the maternal and perinatal outcomes of women referred to the clinic to evaluate clinical practice and inform future service provision. MATERIALS AND METHODS This is a single-centre retrospective study of women referred to the perinatal cardiac service between 2009-2016. Data collected included: demographic details; cardiac diagnosis; pregnancy outcomes, including anaesthetic and delivery complications, and admission to intensive care unit (ICU)/high dependency unit (HDU). RESULTS One hundred and fifty-two women were referred for care in 165 pregnancies. Congenital heart disease was the most common indication for referral (35%), followed by maternal cardiac arrhythmia (26%) and valvular disease (18%). The perinatal mortality rate was 2%, median gestational age at delivery was 38 weeks 4 days, fetal growth restriction (customised birthweight

Abstract Objective Using a system, which accuracy is equivalent to the gold standard Douglas Bag (DB) technique for measuring oxygen consumption (VO2), carbon dioxide generation (VCO2), and respiratory quotient (RQ), we aimed to continuously measure these metabolic indicators and compare the values between post-cardiothoracic surgery and critical care patients. Methods This was a prospective, observational study conducted at a suburban, quaternary care teaching hospital. Age 18 years or older patients who underwent mechanical ventilation were enrolled. Results We included 4 post-surgery and 6 critical care patients. Of those, 3 critical care patients died. The longest measurement reached to 12 h and 15 min and 50 cycles of repeat measurements were performed. VO2 of the post-surgery patients were 234 ± 14, 262 ± 27, 212 ± 16, and 192 ± 20 mL/min, and those of critical care patients were 122 ± 20, 189 ± 9, 191 ± 7, 191 ± 24, 212 ± 12, and 135 ± 21 mL/min, respectively. The value of VO2 was more variable in the post-surgery patients and the range of each patient was 44, 126, 71, and 67, respectively. SOFA scores were higher in non-survivors and there were negative correlations of RQ with SOFA. Conclusions We developed an accurate system that enables continuous and repeat measurements of VO2, VCO2, and RQ. Critical care patients may have less activity in metabolism represented by less variable values of VO2 and VCO2 over time as compared to those of post-cardiothoracic surgery patients. Additionally, an alteration of these values may mean a systemic distinction of the metabolism of critically ill patients.

AbstractTwo-year colleges provide the opportunity for students of all ages to try new subjects, change careers, upskill, or begin exploring higher education, at affordable rates. Many might begin their exploration by taking a course at a local two-year college. Currently, not many of these institutions in the U.S. offer data science courses. This article introduces the perspective lens of students who have gone through the Montgomery College Data Science Certificate Program. We found that, contrary to many other educational fields at the College, data science students tend to come from diverse backgrounds and career paths. A common theme emerged that all students learned valuable skills and applications such as coding in various programming languages and approaches to machine learning. Other meaningful themes included an appreciation of course accessibility, especially catered toward busy professionals who might only be able to take evening courses. Students appreciated learning that data science and ethics are intertwined. Finally, it was evident that going through the data science program positively impacted the lives and careers of these students. The implications of the themes of these student experiences are discussed as they relate to data science education. Supplementary materials for this article are available online.

The reduction of visible particles in injectable products is an important element in the consistent delivery of high-quality parenteral products. An important part of this effort is the control of particles that may emanate from the primary packaging materials. The Parenteral Drug Association (PDA), with the support of the Pharmaceutical Manufacturers Forum (PMF) has undertaken the task of developing test methods to assess the cleanliness of primary packaging components used in the manufacture of sterile injectable products. Further work is focused on end-to-end analysis of the supply chain to identify additional points where particles may enter the finished product workflow. This includes shipment, receipt, transfer and fill and finishing operations. This information and appropriate corrective actions and control methods, coupled with appropriate patient risk-based acceptance limits, are intended to provide better and more consistent supply of injectable products that meet current compendial and Good Manufacturing (GMP) expectations. Aligning control limits between supplier and pharmaceutical manufacturers will offer further improvement. This paper describes the formation of a task force to address these needs and current progress to date.

The fields of Economic Geography and International Business share an interest in the same phenomena, whilst each provides both a differing perspective and different research methods in attempting to understand those phenomena. The Routledge Companion to the Geography of International Business explores the nature and scope of inter-disciplinary work between Economic Geography and International Business in explaining the central issues in the international economy. Contributions written by leading specialists in each field (including some chapters written by inter-disciplinary teams) focus on the nature of multinational firms and their strategies, where they choose to locate their activities, how they create and manage international networks and the key relationships between multinationals and the places where they place their operations. Topics covered include the internationalisation of service industries, the influence of location on the competitiveness of firms and the economic dynamism of regions and where economic activity takes place and how knowledge, goods and services flow between locations. The book examines the areas for fruitful inter-disciplinary work between International Business and Economic Geography and sets out a road map for future joint research, and is an essential resource for students and practitioners of International Business and Economic Development.

When, during my psychoanalytic training, my analyst agreed that I was ready to take on a training case, the important question of the choice of a supervisor arose. I began, in my analysis, to approach the subject, expecting my analyst Enid Balint to be her usual thoughtful self, and that we might have the time to discuss which of her colleagues to approach to discuss possible vacancies. I had some views; there were analysts that I did not want to consult as well as some whose work I liked. However, my analyst surprised me with an unexpected and uncharacteristic intervention; she told me that I should of course contact Donald Winnicott, whom she believed had a vacancy for supervision, and do it soon, since he had a serious cardiac condition and was likely to die in the near future. If I didn’t go to him fairly quickly the opportunity would be lost. She added that it was unfortunate, since he would have made a better supervisor for a second case, rather than a first one, but she thought he was so ill that he probably would not be around when the time came for me to take a second person on.
