Authors: Sohrabi Majid , Abbasi Marjan , Karimi Mohammad 
Published: November 2022

Particulate matter and spread of viruses, including COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are two of the most serious problems because of their significant threat to human health. Here, we fabricate ultrafine and bimodal structured polyamide-6 nanofiber/nets (PA-6 NFN) membrane via one-step electrospinning/netting. The PA-6 NFN membranes include ultrafine (∼70 nm) nanofibers and two-dimensional (2D) ultrathin (∼20 nm) nanonets. These membranes are optimized by facilely regulating the solution concentration, incomplete phase separation by adding NaCl, and also applying a high voltage of 22 kV. With integrated properties of small pore size, high porosity, high specific surface area of 108.8 m2/g, and robust tensile strength of 13.70 MPa, the resultant PA-6 NFN membranes exhibit high filtration efficiency of 99.11%, low pressure drop of 81 Pa, and higher quality factor compared to the two standard commercial masks which consist of three-ply surgical mask and respirator face mask. It can include bacteria, fungi, and also viruses including SARS-CoV-2 (with a diameter of about 100 nm). Additionally, after 24 h of operation of the filtration process in a simulated living environment, the obtained air filter still displayed a high filtration efficiency and a less variation pressure drop that shows the long-term performance of PA-6 NFN membranes. In addition, the R2 value was 0.99, which indicates that the calculation results are in good agreement with the measured results. The fabrication of PA-6 NFN membrane makes it a promising candidate for PM0.3 governance at applications including face mask, protective clothing, clean room, and engine intake.
Factors Influencing Postoperative Residual Diastasis after the Operative Treatment of Acute Lisfranc Fracture-Dislocation
Authors: Choi Jun Young , Suh Jin Soo 
Published: November 2022

Category: Trauma; Midfoot/Forefoot Introduction/Purpose: Clinically, surgeons may frequently encounter residual diastasis between the medial cuneiform and 2nd metatarsal base after the operative treatment of acute Lisfranc fracture-dislocations. The purpose of this study was to identify factors influencing postoperative residual diastasis. We specifically focused on the preoperative fracture pattern using 3- dimensional computed tomography (3D-CT). Methods: Radiographic and clinical findings of 66 patients who underwent operative treatment for acute Lisfranc fracture- dislocation were reviewed. Patients were grouped according to residual diastasis evaluated by weight-bearing anteroposterior radiograph of the foot at the final follow-up. Residual diastasis was defined as distance between the medial cuneiform and 2nd metatarsal base greater than the distance on the contralateral side by 2 mm or more. Demographic parameters and fracture patterns based on preoperative foot 3D-CT were compared. A paired t-test was used to compare continuous numeric parameters, while a chi-square test was used for the proportional parameters. Statistical significance was set at P-value less than 0.05 for all analyses. Results: The mean age at operation, sex, body mass index, and the rate of underlying diabetes were not significantly different between the two groups (P>0.05 each). Preoperative foot 3D-CT evaluation showed that the rate of large (>25% of 2nd tarsometatarsal joint involvement), displaced (>2 mm) fracture fragments on the plantar side of the 2nd metatarsal base was more pronounced in the group with residual diastasis (P=0.001), while medial wall avulsion of the 2nd metatarsal base was more frequent in the group without residual diastasis (P=0.001). Conclusion: While treating acute Lisfranc injuries, surgeons should be aware of the presence of a 2nd metatarsal base plantar fracture. A dorsoplantar inter-fragmentary fixation can be considered if the fragment is large and displaced.

Published: November 2022

Abstract
Background
Observational studies on the prevalence of premonitory symptoms in people with migraine, preceding the headache pain (or aura) phase, have shown conflicting results. We conducted a systematic review and meta-analysis to estimate the prevalence, and relative frequency among clinic populations, of premonitory symptoms in people with migraine, overall and of the multifarious individual symptoms, and to review the methodologies used to assess them.

Methods
We searched PubMed and Embase for studies published from database inception until 31st of May 2022. Two investigators independently screened titles, abstracts, and full texts. We retrieved observational studies that reported the prevalence/relative frequency of one or more premonitory symptoms in people with migraine. Two investigators independently extracted data and assessed risk of bias. Results were pooled using random-effects meta-analysis. Our main outcomes were the percentage of people with migraine who experienced at least one premonitory symptom and the percentages who experienced different individual premonitory symptoms. To describe our outcomes, we used the terms prevalence for data from population-based samples and relative frequency for data from clinic-based samples. We also descriptively and critically assessed the methodologies used to assess these symptoms.

Results
The pooled estimated prevalence in population-based studies of at least one premonitory symptom was 29% (95% CI: 8–63; I2 99%) and the corresponding pooled estimated relative frequency in clinic-based studies was 66% (95% CI: 45–82; I2 99%). The data from clinic-based studies only supported meta-analysis of 11 of 96 individual symptoms, with relative frequency estimates ranging from 11 to 49%. Risk of bias was determined as high in 20 studies, moderate in seven, and low in two.

Conclusions
The substantial between-study heterogeneity demands cautious interpretation of our estimates. Studies showed wide methodological variations, and many lacked rigor. Overall, the evidence was insufficient to support reliable prevalence estimation or characterization of premonitory symptoms. More data are needed, of better quality, to confirm the existence of a distinctive premonitory phase of migraine, and its features. Methodological guidelines based on expert consensus are a prerequisite.

Authors: Taher Ahmed , Glazer Peter , Culligan Chris , Crump Stephanie , Guirguis Steven , Jones Jennifer , Dharamsi Alia , Chartier Lucas B. 
Published: November 2022

Abstract
Background
Decreasing healthcare provider (HCP) exposure to the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus in emergency departments (EDs) is crucial. Approaches include limiting the HCP presence and ensuring sealed isolation rooms, which can result in communication difficulties. This quality improvement (QI) initiative aimed to decrease by 50% duration of isolation room door opening and increasing HCP-perceived communication clarity by one point on a five-point Likert scale.

Methods
This was a prospective, multi-stage project with three Plan-Do-Study-Act (PDSA) cycles between May and July 2020: (1) an educational intervention, (2) the introduction of a novel transceiver communication device, and (3) utilizing a clinical champion. Statistical Process Control XbarR charts were used to assess for special cause variation, and two-tailed Mann-Whitney U tests were used for statistical significance between Likert survey means. Qualitative responses underwent thematic analysis.

Results
Observation of 174 patient encounters was completed over 33 days, with 95 meeting the inclusion criteria. Door opening decreased from baseline (n=40; mean 72.97%) to PDSA 3 (n=21; mean 1.58%; p<0.0001). HCP-perceived communication clarity improved from baseline (n=36; mean 3.36) to PDSA-3 (n=49; mean 4.21; p<0.001). Survey themes included positive effects on communication and workflow, with some challenges on the integration of the new device into the clinical workflow. HCP-perceived errors, workarounds, and workflow pauses showed significant improvements.

Conclusion
This QI initiative with a novel transceiver showed significant decreases in isolation room door opening and increases in communication clarity. Future work will expand to operating rooms and intensive care units.
Nanoparticles for MRI-guided radiation therapy: a review
Authors: Smith Leon , Byrne Hilary L. , Waddington David , Kuncic Zdenka 
Published: November 2022

AbstractThe development of nanoparticle agents for MRI-guided radiotherapy is growing at an increasing pace, with clinical trials now underway and many pre-clinical evaluation studies ongoing. Gadolinium and iron-oxide-based nanoparticles remain the most clinically advanced nanoparticles to date, although several promising candidates are currently under varying stages of development. Goals of current and future generation nanoparticle-based contrast agents for MRI-guided radiotherapy include achieving positive signal contrast on T1-weighted MRI scans, local radiation enhancement at clinically relevant concentrations and, where applicable, avoidance of uptake by the reticuloendothelial system. Exploiting the enhanced permeability and retention effect or the use of active targeting ligands on nanoparticle surfaces is utilised to promote tumour uptake. This review outlines the current status of promising nanoparticle agents for MRI-guided radiation therapy, including several platforms currently undergoing clinical evaluation or at various stages of the pre-clinical development process. Challenges facing nanoparticle agents and possible avenues for current and future development are discussed.

Published: November 2022

Abstract
Objective
Vulnerable plaques with fibrous cap thickness (FCT) of ≤65 μm are prone to rupture and/or thrombosis. However, plaques with FCT > 65 μm cause acute myocardial infarction and even sudden death. We aimed to investigate the relationship between 65 < FCT ≤ 80 μm and plaque rupture and/or thrombosis using optical coherence tomography (OCT).

Methods
OCT was performed on culprit lesions in 502 consecutively enrolled patients to identify FCT. Patients were classified into three groups according to FCT: Group A (FCT ≤ 65 μm, n = 147), Group B (65 < FCT ≤ 80 μm, n = 84) and Group C (FCT > 80 μm, n = 271). Clinical and laboratory data was collected from the inpatient medical record system.

Results
Plaques with thinner FCT, especially < 65 μm, were more susceptible to rupture and/or thrombosis (P < 0.001). Plaques with FCT between 65 and 80 μm had a higher probability of rupture and/or thrombosis than those with FCT > 80 μm (P < 0.001). In multivariable analysis, FCT ≤ 65 μm and 65 < FCT ≤ 80 μm were independent predictors for plaque rupture ([FCT ≤ 65 μm vs. FCT > 80 μm]: OR = 8.082, 95% CI = 4.861 to 13.435, P < 0.001; [65 < FCT ≤ 80 μm vs. FCT > 80 μm]: OR = 2.463, 95% CI = 1.370 to 4.430, P = 0.003), thrombosis ([FCT ≤ 65 μm vs. FCT > 80 μm]: OR = 25.224, 95% CI = 13.768 to 46.212, P < 0.001; [65 < FCT ≤ 80 μm vs. FCT > 80 μm]: OR = 3.675, 95% CI = 2.065 to 6.542, P < 0.001) and plaque rupture with thrombosis ([FCT ≤ 65 μm vs. FCT > 80 μm]: OR = 22.593, 95% CI = 11.426 to 44.674, P < 0.001; [65 < FCT ≤ 80 μm vs. FCT > 80 μm]: OR = 4.143, 95% CI = 1.869 to 9.184, P < 0.001).

Conclusions
OCT-assessed 65 < FCT ≤ 80 μm was independently associated with increased risk of plaque rupture and/or thrombosis compared with FCT > 80 μm.

Authors: Chen Jinlan , Gong Xueyang , Xie Li , Wu Qin , Zhao Tianli , Hu Shijun 
Published: November 2022

Abstract
Background
Cardiac epicardium hemangiomas are exceedingly rare; however, they can cause significant hemodynamic impairment and large pericardial effusions. On rare occasion, cardiac tumors coexist with malformations of the heart.

Case presentation
We present the case of a 10-month-old female infant with a rare cardiac surface hemangioma coexisting with malformations of the heart. It revealed an atrial septal defect (ASD) coexisting with an abnormal occupying lesion with high echogenicity. It was 35*12*9 mm in size and was found in the anterior atrioventricular junction to the posterior atrioventricular junction at the bottom of the ventricular septum by transthoracic echocardiography. We performed surgical treatment of the atrial septal defect and performed biopsy with the occupying lesion. The histopathological examination reported a benign tumor as hemangioma. As far as we know, this is the first case in which cardiac surface hemangioma was found to coexist with an atrial septal defect.

Conclusions
Cardiac epicardium hemangiomas is a rare solid tumor of the heart. If the mass is impossible to resect and does not cause hemodynamic impairment, only mass biopsy is possible.
Congenital coronary artery-left ventricular multiple micro-fistulas and hypertrophic cardiomyopathy: a case report and literature review
Authors: Liu Yue , Wang Zhiyuan , Zeng Hong , Yang Sibao , Li Xiangdong 
Published: November 2022

Abstract
Background
Coronary artery-left ventricular multiple micro-fistulas (CA-LVMMFs) is a rare congenital vascular anomaly that may present with no obvious clinical symptoms or a typical angina attack. CA-LVMMFs is usually found unexpectedly during coronary angiography (CAG).

Case presentation
We report a case of a 65-year-old man admitted to the hospital with acute coronary syndrome. CA-LVMMFs was found during coronary angiography. Echocardiography showed apical hypertrophy and blood flow signals were seen in the apical myocardium, connected with the left ventricle. We searched the MEDLINE database and found 39 relevant reports. We made statistics on the clinical characteristics of these patients and found half involved hypertrophy or perfusion defects in the ventricular septum or apex.

Conclusion
As a rare congenital anomaly, the effect of CA-LVMMFs on patients is unclear. By reporting a case and summarizing literature reports, we found that CA-LVMMFs may be associated with myocardial hypertrophy, especially ventricular septal and apical hypertrophy.

Published: November 2022

Abstract
Background
Hyperkalemia can lead to fatal cardiac arrhythmias. Ten units of intravenous (IV) regular insulin with 25 g of glucose is the mainstay for treating hyperkalemia. However, the most important complication of this treatment is hypoglycemia. We aimed to develop a scoring model to predict hypoglycemia after the treatment of hyperkalemia.

Methods
A retrospective study was conducted at a university-based hospital between January 2013 and June 2021. We included the hyperkalemic patients (> 5.3 mmol/L) who were ≥ 18 years old and treated with 10 units of IV regular insulin with 25 g of glucose. Incomplete data on posttreatment blood glucose, pregnancy, and diabetes mellitus were excluded. Endpoint was posttreatment hypoglycemia (≤ 70 mg/dL or ≤ 3.9 mmol/L). Multivariable logistic regression was used to establish a full model and a subsequently reduced model using the backward elimination method. We demonstrated the model performance using the area under the receiver operating characteristic curve (AuROC), calibration plot, and Hosmer–Lemeshow goodness-of-fit test. Internal validation was done with a bootstrap sampling procedure with 1000 replicates. Model optimism was estimated.

Results
Three hundred and eighty-five patients were included, with 97 posttreatment hypoglycemia (25.2%). The predictive model comprised the following three criteria: age > 60 years old, pretreatment blood glucose ≤ 100 mg/dL (≤ 5.6 mmol/L), and pretreatment potassium > 6 mmol/L. The AuROC of this model was 0.671 (95% confidence interval [CI] 0.608 to 0.735). The calibration plot demonstrated consistency with the original data. Hosmer–Lemeshow goodness-of-fit test showed no evidence of lack-of-fit (p 0.792); therefore, the model was also fit to the original data. Internal validation via bootstrap sampling showed a consistent AuROC of 0.670 (95% CI 0.660 to 0.670) with minimal model optimism. A high risk for posttreatment hypoglycemia was indicated if the patient met at least one of those criteria. Sensitivity and specificity were 95.9% and 14.9%, respectively.

Conclusion
High risk was indicated when at least one of the criteria was met: age > 60 years old, pretreatment blood glucose ≤ 100 mg/dL (≤ 5.6 mmol/L), and pretreatment potassium > 6 mmol/L. Blood glucose levels should frequently check in the high-risk group.

Published: November 2022

Abstract
Background
Cancer and dementia are common in older people and management of the conditions as comorbidities can be challenging, yet little is known about the size or characteristics of this group. We aimed to estimate the prevalence, characteristics and general practice resource usage of people living with both conditions in England.

Methods
Anonymised electronic healthcare records from 391 National Health Service general practices across England using the TPP SystmOne general practice system were obtained from ResearchOne. Data included demographic and clinical characteristics, and general practice healthcare useage (appointments, prescriptions, referrals and secondary care contacts) for people aged 50 and over with a cancer and/or dementia diagnosis consistent with the Quality and Outcomes Framework between 2005 and 2016. Multi-level negative binomial regression was used to analyse the association between having cancer and/or dementia and the number of general practice appointments.

Results
Data from 162,371 people with cancer and/or dementia were analysed; 3616 (2.2%) people were identified as having comorbid cancer and dementia. Of people with cancer, 3.1% also had dementia, rising to 7.5% (1 in 13 people) in those aged 75 and over. Fewer people with both conditions were female (50.7%) compared to those with dementia alone (65.6%) and those with comorbid cancer and dementia were older than those with cancer alone [mean ages 83 (sd = 7), 69 (sd = 12) respectively]. Those with both conditions were less likely to have lung cancer than those with cancer alone (7.5% vs. 10.3%) but more likely to have prostate cancer (20.9% vs. 15.8%). Additional comorbidities were more prevalent for those with both conditions than those with cancer or dementia alone (68.4% vs. 50.2% vs. 54.0%). In the year following the first record of either condition, people with cancer and dementia had 9% more general practice appointments (IRR:1.09, 95% CI:1.01–1.17) than those with cancer alone and 37% more appointments than those with dementia alone (IRR: 1.37, 95% CI: 1.28–1.47).

Conclusions
A significant number of people are living with comorbid cancer and dementia in England. This group have additional comorbidity and higher general practice usage than those with cancer/dementia alone. The needs of this group should be considered in future general practice care planning and research.
Abusive episodes among home-dwelling persons with dementia and their informal caregivers: a cross-sectional Norwegian study
Authors: Steinsheim Gunn , Saga Susan , Olsen Bonnie , Broen Helene Kjeka , Malmedal Wenche 
Published: November 2022

Abstract
Background
Elder abuse is a serious issue with a global prevalence of 15.7% in the community setting. Persons with dementia are at higher risk of elder abuse than the older population in general. With a high and increasing prevalence of dementia this issue cannot be neglected. Hence, the aims of this study were 1) to describe the proportion of abusive episodes among home-dwelling persons with dementia and their informal caregivers, and 2) to explore differences between informal caregivers who have reported committing and not committing abusive acts.

Methods
A cross-sectional survey was conducted among informal caregivers of home-dwelling persons with dementia in Norway from May to December 2021 with a total of 549 participants.

Results
Two-thirds of informal caregivers had committed at least one abusive episode toward the person with dementia in the past year (63.5% psychological abuse, 9.4% physical abuse, 3.9% financial abuse, 2.4% sexual abuse, 6.5% neglect). One-third of informal caregivers had experienced aggression from the person with dementia (33.9% psychological abuse, 7.8% physical abuse, 1.1% financial abuse, 1.4% sexual abuse). Tests for independence showed that the risk of abusive episodes from informal caregivers toward persons with dementia was higher when the informal caregiver was a spouse/partner of the person with dementia and if they experienced aggression from the person with dementia.

Conclusions
The results demonstrate that a majority of informal caregivers commit some form of abusive episodes, and episodes that fall within the scope of psychological abuse are most frequent. This study expands knowledge about elder abuse among home-dwelling persons with dementia. Increased understanding of the dynamics of abuse is essential to be able to reduce risk and prevent abuse.
