Introduction: About 100,000 individuals in the United States live with sickle cell disease (SCD). Palliative care (PC) can improve symptom management for these individuals. The purpose of the study was to explore (a) the experiences of people living with SCD, and (b) their knowledge and perceptions of PC. Method: Using a qualitative, descriptive design, adults with SCD were recruited from a foundation in the southeastern United States. Data included social and SCD-related demographics and audio-recorded, semi-structured focus groups. Analysis took a thematic analysis approach. Results: Participants: There were 16 African Americans who participated in the study, 75% of whom were females, and aged 22 to 71 years. Five themes were identified: unique and unpredictable impact of SCD on daily life, the changing experience of SCD over time, stigmatization/marginalization in health care interactions, perceptions of support in managing SCD symptoms/crises, and PC: “What is it?” Discussion: Participants lacked PC knowledge. PC should be offered to individuals with SCD as part of comprehensive SCD management.

Published: January 2022

Introduction: The mechanical complications of acute myocardial infarction (AMI) still kill despite the evolution of medicine. Early diagnosis and adequate management are necessary to improve the prognosis, and this requires first, a good clinical examination that should raise the suspicion of a mechanical complication, then the echocardiography is performed to confirm the diagnosis. Case Presentation: We present a case of a 64-year-old patient admitted to the emergency room for jaundice with delayed ST-segment elevation myocardial infarction (STEMI). Physical examination revealed signs of right heart failure, which led us to associate jaundice with signs of acute liver failure secondary to right heart failure. Echocardiography confirmed the diagnosis of a ventricular septal rupture (VSR) with left-right shunt, and a significant dilation of the right ventricle. The patient underwent surgical closure of the VSR with fatal evolution. Discussion: VSR is a rare life-threatening mechanical complication of AMI. The clinical signs depend on the left-right shunt and the onset of heart failure, which are 2 major determinants of the therapeutic strategy and the timing of the surgery. Despite surgical closure of the VSR, the mortality remains high, but the prognosis is better in patients treated with surgery than in patients who are treated medically only. Conclusion: The clinical presentation of VSR may differ from a patient to another. Good clinical sense and echocardiography are essential to set early diagnosis, and thus decide on the adequate management at the right time.

Purpose: The purpose of the paper is to report the clinical outcomes of 4 patients with ruptured abdominal aortic aneurysm (AAA) during (3 patients) or immediately after (1 patient) moderate-severe SARS-CoV-2 infection. We discuss COVID-19-related mechanisms which could impact AAA rupture. Patients and Methods: During the period of the pandemic (March 2020—May 2021), we performed surgery in 18 patients with ruptured AAA. Four patients were affected by moderate or severe SARS-CoV-2 infection (in 3 patients the rupture occurred during the infection and in 1 patient 3. months after discharge from the hospital). Two patients underwent open repair and 2 endovascular surgery. Results: No postoperative mortality and no major complication occurred. Rapid growth of the AAA in comparison with a previous Duplex scan was evident in all 4 patients. Conclusions: Family doctors and vascular surgeons should be aware about the possibility of AAA degeneration in patients with moderate-severe COVID19 infection. The risk is increased by steroid therapy which is essential in more advanced stages of the infection. In this clinical setting, endovascular repair is a valid choice.

Published: January 2022

Purpose: Patients with a hyperangulated (>60°) proximal aortic neck and at high risk of open surgery have been treated with endovascular aortic repair (EVAR). However, long-term outcomes are not well reported. The aim of this study is to compare the technical and clinical success of EVAR in angulated (45°-60°) and hyperangulated (>60°) proximal neck angulation. Materials and Methods: The data of all consecutive patients undergoing EVAR treated between November 2007 and February 2020 were collected. A retrospective analysis of this prospective database was performed. The primary measure outcome was technical and clinical success. In addition, we evaluated sack evolution, type IA endoleak, secondary procedures, aneurysm rupture, mortality, aneurysm-related mortality, and migration. Results: In all, 246 of 1353 EVAR patients presented with an angulation of the proximal neck >45°, 130 patients presented with an infrarenal angulation >60°, while 116 patients had an angulation between 45° and 60°. Patients with a hyperangulated infrarenal aortic neck were significantly more often women (8.6% vs 26.9%), older (73.9 vs 76.7 years), and had less often diabetes mellitus (20.7% vs 10.8%). Suprarenal neck angulation and reversed tapered neck were significantly more frequent in the hyperangulated group so that propensity scores were generated using these anatomical parameters to create a matched cohort group. No significant differences in technical (87.9% vs 94.8%) and clinical success (66.4% vs 69.8%) were observed. After a mean clinical follow-up of 58.9 months significantly more secondary procedures were performed in the hyperangulated group (23.3% vs 12.9% p=0.04); however, neck-related secondary procedures were comparable (1.7% vs 6.0%; p=0.09). Also, all-cause and aneurysm-related mortality, sack evolution, type IA endoleak, aneurysm rupture, and migration were comparable for both groups. Conclusion: Compared with less angulated proximal aortic neck, hyperangulated neck anatomy did not reduce the technical and clinical success of EVAR but increased the risk of secondary procedures. In patients who are not good candidates for open surgery, EVAR is a reasonable alternative.

Published: January 2022

Background: The history of intracranial hemorrhage (ICrH) is considered a contraindication for intravenous thrombolysis (IVT) among patients with acute ischemic stroke (AIS). Objective: This study aimed at comparing the safety of IVT among patients with and without a history of ICrH. Methods: We performed a systematic review of the literature. Data regarding all AIS patients with prior ICrH who received IVT were retrieved. Meta-analysis was performed to compare the rate of symptomatic hemorrhagic transformation (sHT), death within 90 days, and favorable and unfavorable 90-day functional outcomes based on modified Rankin Scale (mRS) among stroke patients with and without prior ICrH. Results: Out of 13,032 reviewed records, 7 studies were included in the systematic review and meta-analysis. Quantitative synthesis of data regarding the rate of sHT (5068 patients) revealed no significant difference between the two groups [odds ratio, OR: 1.55 (0.77, 3.12); p = 0.22]. However, a significantly higher risk of death within 90 days [OR: 3.91 (2.16, 7.08); p < 0.00001] and a significantly higher 90-day poor functional outcomes (mRS, 4–6) [OR: 1.57 (1.07, 2.30); p = 0.02] were observed among patients with prior ICrH. Likewise, the percentage of 90-day good functional outcomes (mRS, 0–1) was lower in the prior ICrH group [OR: 0.54 (0.35, 0.84); p = 0.06]. Subgroup analyses in patients with a history of ICrH (based on both patients’ medical history and imaging confirmation) revealed no significant between-group differences in rates of sHT. Also, sensitivity analysis consisting of only studies using standard-dose IVT showed no difference in sHT rates and 90-day outcomes between the two groups. There was no evidence of heterogeneity ( I2 >50%) among included studies. Conclusion: The results of this study indicated that prior history of ICrH does not increase the risk of sHT post-IVT, but it is associated with a higher risk of death and poor functional outcomes in 90 days.

Published: January 2022

Background: Immunosuppression nonadherence may be the most important factor limiting long-term allograft survival. Objective: Following user-centered design, we explored the essential priorities and preferences of kidney transplant recipients and healthcare providers (HCP) to inform development of a smartphone app to improve immunosuppression adherence and communication. Design: A qualitative descriptive research design was used. Setting: The University of Alberta Hospital adult kidney transplant program in Edmonton, Canada. Participants: Participants were recruited by convenience sampling and included 32 kidney transplant recipients and 11 HCPs. Methods: Seven focus groups (5 with recipients and 2 with HCPs) were conducted to inform app development. Sessions were recorded, and transcripts were coded to elucidate themes. Results: App development to improve adherence was not a priority for HCP. Recipients prioritized choice: that all features be optional. Recipients preferred support while traveling; access to laboratory results; and use by younger or newly transplanted recipients. Both recipients and HCP preferred linkage to pharmacy; and self-management and accountability. For the app to improve communication, HCPs believed the priorities to be addressed included: clarity on scope of app; legal, ethical, and professional obligations; and charting. Both recipients and HCP prioritized HCP workload, and broader medication and health concerns. Healthcare providers preferred tech support; both recipients and HCPs preferred app access for nontransplant HCP. Limitations: Limitations include underrepresentation of physicians, recipients with racial/ethnic diversity, and potential selection bias of transplant recipients who perceived themselves to be adhering to immunosuppression medications. Conclusion: Future research is needed for the app to become a comprehensive, secure platform for broader communication between recipients and HCP, pharmacies, and nontransplant clinicians while streamlining HCP workload.

Published: January 2022

Objectives: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a pathological condition which leads to high healthcare-related costs and low quality of life for patients. The introduction of new biological therapies (monoclonal antibodies, MAbs) in CRSwNP patients has allowed new therapeutic options for non-responders to conventional therapies and Dupilumab represents the first approved biological agent. The aim of this paper is to provide a practical clinical multidisciplinary protocol which might help clinicians involved in this field to monitor the clinical outcomes. Methods: Our centre of Rhinology and Rhino-Allergology has developed a dedicated collection form to observe the outcomes of patients treated with Dupilumab. Our research started from the indications given in EPOS 2020 as main reference. We then implemented these references in an electronic database trying to apply Evidence Based Medicine (EBM) in current clinical practice. Results: The result consists of three parts: an anamnestic collection data, a clinician reported outcome and two patient reported outcomes (PROMs) questionnaire, the visual analogue scale (VAS) and the Sino-Nasal Outcome Test-22 (SNOT-22). The tables we propose should provide an adequate correlation with the patients’ adherence to therapy and their treatment outcomes. Such periodical evaluation (after a month, after 3 months, after 6 months and at one year) should quickly allow to monitor if the patient is correctly assuming the therapy and the eventual objective improvements. Conclusions: We propose a practical monitoring protocol formulated to analyse both objective and subjective aspects of patients with severe uncontrolled CRSwNP treated with MAbs, thus helping to define in future a better comparison between the clinical results of different institutes.

Abstract
Background
Angiography headache (AH) is common but not negligible, and the criteria for AH have been based on only a few studies. The purpose of this study was to investigate the incidence, risk factors and possible mechanism of AH and reappraise the diagnostic criteria for AH in the International Classification of Headache Disorders 3 (ICHD-3).

Methods
Two hundred and seventy-nine patients completed this prospective, non-randomized study, including 107 patients who underwent cerebral angiography, 101 patients who underwent coronary intervention and 71 patients who underwent extremities arterial intervention. Patients were followed up with questionnaires immediately after the procedure and 24 h, 72 h, 1 week and 2 weeks after the procedure.

Results
The incidence of headache was 22.4% (24/107) in cerebral angiography group, 23.8% (24/101) in coronary intervention group, and 16.9% (12/71) in extremities arterial intervention group. Headache still occurred in 12.1% (13/107), 14.9% (15/101) and 11.3% (8/71) of patients 24 h after the procedure in the three groups, respectively. Two types of headache were observed in cerebral angiography group and coronary intervention group, one during and one after the procedure, while only postoperative headache was observed in extremities arterial intervention group. Previous headache history was a risk factor for headache in the three groups (p = 0.003 in cerebral angiography group, p = 0.006 in coronary intervention group, and p = 0.016 in extremities arterial intervention group). In addition, female (p = 0.008) was a risk factor for cerebral angiography group. Headache characteristics were described in detail.

Conclusions
The diagnostic criteria for 6.7.2 angiography headache in ICHD-3 may miss a number of cerebral AH with onset later than 24 h after the procedure. Therefore, it is recommended to revise it according to the literature and further studies. The incidence of headache was high during and after angiography and interventional procedure. It was suggested that the definition of headache due to coronary intervention and headache due to extremities arterial intervention should be added in ICHD.
CBMOS: a GPU-enabled Python framework for the numerical study of center-based models
Authors: Mathias Sonja , Coulier Adrien , Hellander Andreas 
Published: January 2022

Abstract
Background
Cell-based models are becoming increasingly popular for applications in developmental biology. However, the impact of numerical choices on the accuracy and efficiency of the simulation of these models is rarely meticulously tested. Without concrete studies to differentiate between solid model conclusions and numerical artifacts, modelers are at risk of being misled by their experiments’ results. Most cell-based modeling frameworks offer a feature-rich environment, providing a wide range of biological components, but are less suitable for numerical studies. There is thus a need for software specifically targeted at this use case.

Results
We present CBMOS, a Python framework for the simulation of the center-based or cell-centered model. Contrary to other implementations, CBMOS’ focus is on facilitating numerical study of center-based models by providing access to multiple ordinary differential equation solvers and force functions through a flexible, user-friendly interface and by enabling rapid testing through graphics processing unit (GPU) acceleration. We show-case its potential by illustrating two common workflows: (1) comparison of the numerical properties of two solvers within a Jupyter notebook and (2) measuring average wall times of both solvers on a high performance computing cluster. More specifically, we confirm that although for moderate accuracy levels the backward Euler method allows for larger time step sizes than the commonly used forward Euler method, its additional computational cost due to being an implicit method prohibits its use for practical test cases.

Conclusions
CBMOS is a flexible, easy-to-use Python implementation of the center-based model, exposing both basic model assumptions and numerical components to the user. It is available on GitHub and PyPI under an MIT license. CBMOS allows for fast prototyping on a central processing unit for small systems through the use of NumPy. Using CuPy on a GPU, cell populations of up to 10,000 cells can be simulated within a few seconds. As such, it will substantially lower the time investment for any modeler to check the crucial assumption that model conclusions are independent of numerical issues.

Published: January 2022

Abstract
Background
A mismatch between a widespread use of broad-spectrum antibiotic agents and a low prevalence of reported bacterial co-infections in patients with SARS-CoV-2 infections has been observed. Herein, we sought to characterize and compare bacterial co-infections at admission in hospitalized patients with SARS-CoV-2, influenza or respiratory syncytial virus (RSV) positive community-acquired pneumonia (CAP).

Methods
A retrospective cohort study of bacterial co-infections at admission in SARS-CoV-2, influenza or RSV-positive adult patients with CAP admitted to Karolinska University Hospital in Stockholm, Sweden, from year 2011 to 2020. The prevalence of bacterial co-infections was investigated and compared between the three virus groups. In each virus group, length of stay, ICU-admission and 30-day mortality was compared in patients with and without bacterial co-infection, adjusting for age, sex and co-morbidities. In the SARS-CoV-2 group, risk factors for bacterial co-infection, were assessed using logistic regression models and creation of two scoring systems based on disease severity, age, co-morbidities and inflammatory markers with assessment of concordance statistics.

Results
Compared to influenza and RSV, the bacterial co-infection testing frequency in SARS-CoV-2 was lower for all included test modalities. Four percent [46/1243 (95% CI 3–5)] of all SARS-CoV-2 patients had a bacterial co-infection at admission, whereas the proportion was 27% [209/775 (95% CI 24–30)] and 29% [69/242 (95% CI 23–35)] in influenza and RSV, respectively. S. pneumoniae and S. aureus constituted the most common bacterial findings for all three virus groups. Comparing SARS-CoV-2 positive patients with and without bacterial co-infection at admission, a relevant association could not be demonstrated nor excluded with regards to risk of ICU-admission (aHR 1.53, 95% CI 0.87–2.69) or 30-day mortality (aHR 1.28, 95% CI 0.66–2.46) in adjusted analyses. Bacterial co-infection was associated with increased inflammatory markers, but the diagnostic accuracy was not substantially different in a scoring system based on disease severity, age, co-morbidities and inflammatory parameters [C statistic 0.66 (95% CI 0.59–0.74)], compared to using disease severity, age and co-morbidities only [C statistic 0.63 (95% CI 0.56–0.70)].

Conclusions
The prevalence of bacterial co-infections was significantly lower in patients with community-acquired SARS-CoV-2 positive pneumonia as compared to influenza and RSV positive pneumonia.
Repression of lncRNA PART1 attenuates ovarian cancer cell viability, migration and invasion through the miR-503-5p/FOXK1 axis
Authors: Li Bing , Lou Ge , Zhang Jiahui , Cao Ning , Yu Xi 
Published: January 2022

Abstract
Background
Ovarian cancer (OC) is a female malignant tumor with a high fatality rate. Long non-coding RNAs (lncRNAs) are deeply involved in OC progression. The aim of this study is to explore the specific mechanism of lncRNA prostate androgen-regulated transcript 1 (PART1) in OC.

Methods
Quantitative real time PCR was utilized to determine the expression levels of PART1, microRNA (miR)-503-5p and forkhead-box k1 (FOXK1) in OC tissues and/or cells. The cell viability, migration, and invasion in OC were evaluated by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-h-tetrazolium bromide assay, wound healing assay and transwell invasion assay, respectively. Flow cytometry was used to analyze the cell apoptosis. The xenograft tumor was conducted in nude mice to verify the effect of PART1 knockdown on OC in vivo. The target relationships among PART1, miR-503-5p and FOXK1 were predicted by StarBase, and verified by luciferase reporter assay. The level of FOXK1 was assessed by western blot.

Results
Increased expression of PART1 and FOXK1 was observed in OC tissues or cells, whereas miR-503-5p was downregulated. PART1 silencing or miR-503-5p overexpression repressed the cell viability, migration and invasion, and protomed apoptosis. Meanwhile, miR-503-5p was a target of PART1, and FOXK1 was a direct target gene of miR-503-5p. Both downregulation of miR-503-5p and upregulation of FOXK1 partly relieved the suppressive effects of PART1 knockdown on the oncogenicity of OC in vitro.

Conclusion
Decreased PART1 represses the cell viability, migration and invasion of OC via regulating the miR-503-5p/FOXK1 axis, which provided an underlying target for treating OC.
