Retrieving entrapped guidewire using rotablation technique: case series and literature review
Authors: Li Chen , Chen Zhongxiu , Wang Mian 
Published: July 2022

AbstractBackgroundThe present article summarizes three cases of retrieving entrapped guidewire using rotablation technique.Case summaryAll three cases pertained to guidewire being fractured and entrapped during percutaneous coronary interventions (PCIs) for right coronary artery (RCA) chronic total occlusion in a local hospital. In Case 1, two fractured filaments connecting to the entrapped guidewire could be clearly seen. One filament was in the right brachial artery and the other one was in the ascending aorta. In Case 2, the operator applied buddy wire technique during PCI but forgot to withdraw the second wire before stenting. As a result, the second SION wire was entrapped by the stent and was untangled and fractured when being retrieved. In Case 3, a SION guidewire was entrapped during PCI for RCA. The initial attempt to retrieve the guidewire ended in failure. Although the entrapped guidewire was still intact, it was difficult to advance the floppy rotawire into the RCA as it was still totally occluded. In those scenarios, complete retrieval of the entrapped guidewire using catheter-based technique was hardly possible. Rotablation was used to cut the entrapped guidewire, retrieve the broken end, and leave the remnants in coronary artery jailed by the stent. Clinical and angiographic follow-up observation demonstrated that the patients were free of target vessel failure.DiscussionEntrapment of guidewire is a rare complication of PCI. The management of entrapped guidewire is usually challenging. Rotablation technique is a useful and efficient strategy when conventional methods failed to retrieve the entrapped guidewire.

Published: July 2022

Abstract

Background
Aortic valve disease is the most prevalent valvular abnormality in the developed world and carries a high risk of morbidity and mortality. Transcatheter aortic valve replacement (TAVR) is favoured over open-heart surgery in high-risk patient categories and is increasingly used in lower-risk groups. End stage kidney disease (ESKD) is associated with premature calcific degeneration of bioprosthetic heart valves. Redo-TAVR requires meticulous pre-procedural planning to avoid the important risks of sinus sequestration and impaired coronary access. Transcatheter aortic valve replacement with the Acurate Neo transcatheter heart valve (THV) has been clinically available for a short time only and there are limited reports describing redo-TAVR in the Acurate Neo.

Case summary
We present a case of early, rapid onset, structural valve degeneration in a Acurate Neo, supra-annular, self-expanding THV in a dialysis patient. The patient presented with chest pain and breathlessness 4 years after TAVR with a Acurate Neo for severe stenosis of a bicuspid aortic valve. Echocardiogram now showed severe stenosis of the THV and computed tomography revealed severe THV leaflet calcification but no pannus or leaflet thrombus. After careful pre-procedural planning a S3 Ultra balloon-expandable valve was selected and positioned relatively high to pin the first THV leaflets in a fully open position without compromising coronary artery flow or coronary access.

Discussion
End stage kidney disease may cause rapid, calcific degeneration of TAVR valves leading to presentation with severe aortic stenosis. Redo-TAVR in the Acurate Neo THV with a Sapien 3 Ultra is feasible with careful pre-procedural planning to mitigate the risks of sinus sequestration and impaired coronary access.
A de novo genome assembly of Solanum verrucosum Schlechtendal, a Mexican diploid species geographically isolated from other diploid A-genome species of potato relatives

Published: July 2022

Abstract
There are over 100 known species of cultivated potatoes and their wild relatives. Many of these species, including cultivated potatoes, share the A genome; these species are mainly distributed in South America and are reproductively isolated from Mexican diploid species. The only diploid A-genome species distributed in Mexico is Solanum verrucosum Schlechtendal, which is also a maternal progenitor of Mexican polyploid species. In this study, we constructed a high-quality de novo assembly of the S. verrucosum genome using PacBio long-read sequencing and Hi-C scaffolding technologies. A monohaploid clone (2n = x = 12) of S. verrucosum was used to reduce assembly difficulty due to the heterozygous nature of the species. The final sequence assembly consisted of 780.2 Mb of sequence, 684.0 Mb of which were anchored to the 12 chromosomes, with a scaffold N50 of 55.2 Mb. Putative centromeres were identified using publicly available data obtained via chromatin immunoprecipitation sequencing against a centromere-specific histone 3 protein. Transposable elements accounted for approximately 61.8% (482.1 Mb) of the genome, and 46,904 genes were functionally annotated. High gene synteny and similarity were revealed among the genomes of S. verrucosum, Solanum commersonii, Solanum chacoense, Solanum phureja, Solanum tuberosum, and Solanum lycopersicum. The reference-quality S. verrucosum genome will provide new insights into the evolution of Mexican polyploid species and contribute to potato breeding programs.

Published: July 2022

Abstract

Background and Objectives
Interprofessional education (IPE) is necessary to train health care professionals to work collaboratively for the care of older adults. Geriatric Outreach and Training with Care! (GOT Care!) was an innovative academic training program designed to provide an IPE opportunity for health care students and faculty while providing care to community-dwelling older adults. The objectives of this program evaluation were to: (a) examine students’, older adult participants’, and primary care providers’ (PCPs) perceptions toward their participation GOT Care! and (b) examine patient outcomes to identify program strengths and areas for improvement.

Research Design and Methods
Formative and summative program evaluation methods were utilized to evaluate student, older adult participant, and provider perceptions of participating in GOT Care!. A total of 221 pharmacy, physical therapy, nursing, social work, medicine, and public health students from a single public university in northeastern United States, 38 community-dwelling older adults, and 33 PCPs were included. Means, standard deviations, and percentages were computed for survey data. The contextual data gathered from interviews and open-ended questions were analyzed using Borkan’s immersion–crystallization approach to generate themes.

Results
Overall, the students, older adults, and PCPs appreciated GOT Care!. Students reported learning about the unique challenges to geriatric care and how to communicate with other professionals. The older adults appreciated the thorough interprofessional assessment and that the students could learn from them. The PCPs noted the unique insights into their patients’ health that would not present at a typical office visit.

Discussion and Implications
GOT Care! leveraged academic and community partnerships to provide an IPE opportunity and care to vulnerable older adults. Positive outcomes such as older adult, student, and PCP satisfaction, and a reduction in emergency department visits support ongoing utilization and evaluation of these IPE programs.
The Role of the Built Environment on the Quality of Life for Residents in Long-Term Care Facilities in Asia: A Scoping Review
Authors: Chaudhury Habib , Xu Mingjun 
Published: July 2022

Abstract

Background and Objectives
The quality of the built environmental features in long-term care (LTC) homes significantly influences residents’ functioning (e.g., wayfinding, self-care, and social interaction) and well-being. There is limited research on the characteristics of the built environment of LTC and its influence on residents’ quality of life in countries in the Asia–Pacific region (e.g., East Asia and South Asia). The older adult population in this region is expected to increase significantly in the coming decades. There are distinctive perceptions of nursing home, nursing home environments, and sociocultural norms in this geographic region. Given this context, a better understanding of the built environment of LTC facilities in this region can inform design professionals and policymakers for evidence-based decision-making. The present study undertakes a scoping review of the empirical research on the characteristics and influence of the built environment of LTC facilities on residents’ quality of life in the Asia–Pacific context.

Research Design and Methods
Online relevant databases were used to identify articles published 2000–2021, from which we selected 33 publications.

Results
Three substantive themes were generated from the synthesis of the selected publications. These themes are (a) perceptions of nursing home, (b) impact of the built environment on residents’ quality of life, and (c) assessment of the LTC built environment.

Discussion and Implications
We identified research gaps in understanding the role of the built environment in nursing homes in the particular geographic context and future research directions. Five planning and design principles for LTC were derived from the synthesis of key findings to inform design professionals and policymakers.

SUMMARY
Volcano seismology is an essential tool for monitoring volcanic processes in the advent and during eruptions. A variety of seismic signals can be recorded at volcanoes, of which some are thought to be related to the migration of fluids which is of primary importance for the anticipation of imminent eruptions. We investigate the volcanic crises at Villarrica volcano in 2015 and report on a newly discovered very-long-period (VLP) signal that accompanies phases of periodic long period (LP) signal burst. Despite their low amplitude emergent character, we can locate the source region of the 1 Hz LP signals to the close vicinity of the volcano using a network-based correlation method. The source of the VLP signal with a period of about 30–100 s appears to locate in the vicinity of two stations a few kilometres from the summit. Both stations record very similar VLP waveforms that are correlated with the envelope of the LP bursts. A shallow magma reservoir was inferred by Contreras from surface deformation as the source of inflation following the eruption in 2015. Cyclic volume changes of 6 m3 in this reservoir at 3 km depth can explain the observed amplitudes of the vertical VLP signal. We propose that the LP signal is generated by the migration of gas or gas-rich magma that is periodically released from the inflating reservoir through a non-linear valve structure which modulates the flux, and thereby causes bursts of flow-related LP signals and pressure changes observed as VLP deformation. Our model predicts that the correlated occurrence of LP bursts and VLP surface motion depends on the intensity of the fluid flux. A weaker flux of fluids may not exceed the opening pressure of valve structure, and higher rates might maintain pressure above the closing pressure. In both cases, the VLP signal vanishes. Our observation provides constrains for models of fluid transport inside volcanoes. At Villarrica the VLP signal, and its relation to the LP activity, reveal additional information about fluxes in the magmatic reservoir that might aide forecasting of volcanic activity.
“Many of those who were only wounded suffocated, buried alive”: Analyzing the Experiences of Jews Who Survived Mass Executions
Authors: Engelking Barbara 
Published: July 2022

Abstract
The Holocaust is associated primarily with death camps, but mass executions alongside crematoria were an equal way to exterminate Jews during World War II. This article presents the perspective of Jews who survived the shootings. On the basis of ninety-one personal accounts of people who survived under the corpses, I describe their experience: the circumstances of the massacre, falling into the grave, getting out of it, and returning to the living. In the text, I pose the following questions: what can we learn by analyzing this experience? Does it bring anything new to our knowledge of the Holocaust? Did those once “buried alive” know something that other witnesses do not say? The article complicates received understandings of how, precisely, people died during the Holocaust; and challenges the common assumption in the scholarship that those who survived were all “irreversibly changed.”

Abstract

Background
Cardiovascular disease (CVD) risk prediction models for individuals with type 2 diabetes are important tools to guide intensification of interventions for CVD prevention. We aimed to assess the added value of incorporating risk factors variability in CVD risk prediction for people with type 2 diabetes.

Methods
We used electronic health records (EHRs) data from 83 910 adults with type 2 diabetes but without pre-existing CVD from the UK Clinical Practice Research Datalink for 2004–2017. Using a landmark-modelling approach, we developed and validated sex-specific Cox models, incorporating conventional predictors and trajectories plus variability of systolic blood pressure (SBP), total and high-density lipoprotein (HDL) cholesterol, and glycated haemoglobin (HbA1c). Such models were compared against simpler models using single last observed values or means.

Results
The standard deviations (SDs) of SBP, HDL cholesterol and HbA1c were associated with higher CVD risk (P &lt; 0.05). Models incorporating trajectories and variability of continuous predictors demonstrated improvement in risk discrimination (C-index = 0.659, 95% CI: 0.654–0.663) as compared with using last observed values (C-index = 0.651, 95% CI: 0.646–0.656) or means (C-index = 0.650, 95% CI: 0.645–0.655). Inclusion of SDs of SBP yielded the greatest improvement in discrimination (C-index increase = 0.005, 95% CI: 0.004–0.007) in comparison to incorporating SDs of total cholesterol (C-index increase = 0.002, 95% CI: 0.000–0.003), HbA1c (C-index increase = 0.002, 95% CI: 0.000–0.003) or HDL cholesterol (C-index increase= 0.003, 95% CI: 0.002–0.005).

Conclusion
Incorporating variability of predictors from EHRs provides a modest improvement in CVD risk discrimination for individuals with type 2 diabetes. Given that repeat measures are readily available in EHRs especially for regularly monitored patients with diabetes, this improvement could easily be achieved.

Published: July 2022

Abstract

Background
The epidemiological advantage of Omicron variant is evidenced by its rapid spread and the ability to outcompete prior variants. Among Omicron sublineages, early outbreaks were dominated by BA.1, while BA.2 has gained dominance since February 2022. The relative pathogenicity and transmissibility of BA.1 and BA.2 have not been fully defined.

Methods
We compared viral loads and clinical signs in Syrian hamsters after infection with BA.1, BA.2, or D614G variant. A competitive transmission model and next-generation sequencing were used to compare the relative transmission potential of BA.1 and BA.2.

Results
BA.1 and BA.2 caused no apparent clinical signs, while D614G caused more than 10% weight loss. Higher viral loads were detected in nasal wash samples and nasal turbinate and lung tissues from BA.1-inoculated hamsters compared with BA.2-inoculated hamsters. No aerosol transmission was observed for BA.1 or BA.2 under the experimental condition in which D614G transmitted efficiently. BA.1 and BA.2 were able to transmit among hamsters via direct contact; however, BA.1 transmitted more efficiently than BA.2 under the competitive transmission model. No recombination was detected from direct contacts exposed simultaneously to BA.1 and BA.2.

Conclusions
Omicron BA.1 and BA.2 demonstrated attenuated pathogenicity and reduced transmission potential in hamsters compared with early SARS-CoV-2 strains.

Published: July 2022

Abstract

Objective
In order to manage COVID-19 patient population and bed capacity issues, remote patient monitoring (RPM) is a strategy used to transition patients from inpatients to home. We describe our RPM implementation process for post-acute care COVID-19 pneumonia patients. We also evaluate the impact of RPM on patient outcomes, including hospital length of stay (LOS), post-discharge Emergency Department (ED) visits, and hospital readmission.

Materials and Methods
We utilized a cloud-based RPM platform (Vivify Health) and a nurse-monitoring service (Global Medical Response) to enroll COVID-19 patients who required oxygen supplementation after hospital discharge. We evaluated patient participation, biometric alerts, and provider communication. We also assessed the program’s impact by comparing RPM patient outcomes with a retrospective cohort of Control patients who similarly required oxygen supplementation after discharge but were not referred to the RPM program. Statistical analyses were performed to evaluate the 2 groups’ demographic characteristics, hospital LOS, and readmission rates.

Results
The RPM program enrolled 75 patients with respondents of a post-participation survey reporting high satisfaction with the program. Compared to the Control group (n = 150), which had similar demographics and baseline characteristics, the RPM group was associated with shorter hospital LOS (median 4.8 vs 6.1 days; P=.03) without adversely impacting return to the ED or readmission.

Conclusion
We implemented a RPM program for post-acute discharged COVID-19 patients requiring oxygen supplementation. Our RPM program resulted in a shorter hospital LOS without adversely impacting quality outcomes for readmission rates and improved healthcare utilization by reducing the average LOS.
Taking the Blues Away: The Second Edition of The New Negro
Authors: Hulme Peter 
Published: July 2022

Abstract
Alain Locke’s anthology The New Negro: An Interpretation–universally regarded as the key text for what later became known as the Harlem Renaissance–is usually reported as having been published in 1925 and reprinted in 1927. I argue that the 1927 version should in fact be regarded as a second edition, given the significant excision of the two Miguel Covarrubias drawings that had appeared in the original edition as “Jazz.” One of those drawings, given the title “Blues Dancing,” is analyzed closely via its two other appearances, one in W. C. Handy’s Blues: An Anthology (1926), the other in Vanity Fair, illustrating a story by Covarrubias’s friend, the Caribbean writer Eric Walrond. Attention is paid to the setting of the story, the Sugar Cane Club, often viewed as the epitome of jazz cabarets in Harlem. I then address Locke’s decision to omit the Covarrubias drawings from the second edition of The New Negro through consideration of the events of 1926, arguably the pinnacle of the Harlem Renaissance but a year that saw intense debates about the propriety of representations of jazz in Black writing.
Mapping H i 21-cm in the Klemola 31 group at z = 0.029: emission and absorption towards PKS 2020−370

ABSTRACT
We present MeerKAT Absorption Line Survey (MALS) observations of the H i gas in the Klemola 31 galaxy group (z = 0.029), located along the line of sight to the radio-loud quasar PKS 2020−370 (z = 1.048). Four galaxies of the group are detected in H i emission, and H i absorption is also detected in front of PKS 2020−370 in Klemola 31A. The emission and absorption are somewhat compensating on the line of sight of the quasar, and the derived column density of the absorption appears underestimated, with respect to the neighbouring emission. A symmetric tilted-ring model of Klemola 31A, assuming the absorbing gas in regular rotation in the plane, yields a rather high spin temperature of 530 K. An alternative interpretation is that the absorbing gas is extra-planar, which will also account for its non-circular motion. The Na i/Ca ii ratio also suggests that the absorbing gas is unrelated to cold H i disc. Two of the galaxies in the Klemola group are interacting with a small companion, and reveal typical tidal tails, and velocity perturbations. Only one of the galaxies, ESO 400−13, reveals a strong H i deficiency, and a characteristic ram-pressure stripping, with a total asymmetry in the distribution of its gas. Since a small galaxy group as Klemola 31 is not expected to host a dense intra-group gas, this galaxy must be crossing the group at a very high velocity, mostly in the sky plane.
