Authors: Simonetti Joseph A. , Azrael Deborah , Zhang Wilson , Miller Matthew 
Published: August 2022

AbstractObjectiveSeventy percent of suicides among U.S. veterans are due to firearm injury. Because discussions about firearm access are an important component of evidence‐based suicide prevention programs, we sought to quantify the proportion of U.S. veterans who have discussed firearm safety with a healthcare provider.MethodsData come from a probability‐based, nationally representative online survey of U.S. adults living in households with firearms in 2019 (response 65%). In this study, we include only self‐identified veteran firearm owners. Respondents were asked, “Has a physician or other healthcare practitioner ever spoken to you about firearm safety?” Analyses were stratified by self‐reported use of Veterans Health Administration (VHA) healthcare services.ResultsOverall, 31.5% (95% CI 27.5–35.8) reported using VHA services and 9.2% (95% CI 6.8–12.3) reported that a clinician had ever spoken with them about firearm safety (14.3% among VHA users, 6.8% among non‐users). Of those who reported a discussion, nearly three quarters reported it was with an outpatient primary care physician or medical specialist.ConclusionsA large majority of veteran firearm owners have not had, or do not recall having had, a firearm safety discussion with a clinician, suggesting that additional efforts to facilitate such discussions in the VHA and elsewhere are needed.

AbstractBackgroundPathogen reduction technology (PRT) effectively mitigates bacterial contamination in platelets but is more likely to produce low yield units. Although low dose transfusion using conventional platelets has not been associated with increased bleeding, these findings have not been reproduced with PRT‐treated platelets.Study Design and MethodsPlatelet transfusions in a tertiary adult hospital were retrospectively reviewed. Comparisons were made between PRT‐treated regular (PRT‐PR) and low (PRT‐PL) yield platelets. Outcomes examined included the number of platelets and RBCs transfused, transfusion‐free interval, and corrected count increment (CCI). Subgroup analyses were also performed on hematology–oncology inpatients and outpatients, as well as non‐hematology–oncology patients.ResultsPlatelet utilization per patient remained mostly unchanged (mean 2.9–4.3 units per patient per month) even when the frequency of PRT‐PL transfusion increased. Among 1402 patients examined, the number of platelets and RBCs transfused was not significantly different between patients first transfused with PRT‐PR versus PRT‐PL (mean number of platelet units = 2.8 vs. 3.1, p = 0.38; mean number of RBC units = 4.8 vs. 4.3, p = 0.93). Among 10,257 platelet transfusions examined, the transfusion‐free interval (hazard ratio = 1.05, 95% confidence interval 1.00–1.10) and CCI (10.2 vs. 11.0, p = 0.70) were comparable between PRT‐PR and PRT‐PL units. Similar findings were observed in all subgroups, except for shortened transfusion‐free intervals among hematology–oncology inpatients.ConclusionPRT‐PR and PRT‐PL units may be used in an equivalent manner to maintain an adequate platelet inventory, since there was only a minor difference in time between transfusions.
Hyperbaric treatment of platelets extends in vitro storage to 14 days

AbstractBackgroundPlatelets for transfusion have a storage time of 5–7 days at 22°C–24°C, which results in a strain on the supply chain and supply shortages. We describe a novel method to extend platelet storage using xenon (Xe) gas under high pressure and refrigeration.Study Design and MethodsApheresis platelets (APU) prepared in 65% platelet additive solution (PAS) were stored under standard conditions (SC) at 20°C–24°C to Day 5. Paired APUs were prepared with Xe and stored to Day 14 at 2°C–6°C under hyperbaric conditions (XHC). A standard panel of in vitro assays was conducted.ResultsXHC platelets were viable out to Day 14. The average pH of Day 14 platelets was 6.58, and 86% maintained some degree of swirl compared with 7.02 and 100% swirl for Day 5 SC platelets. The rate of glycolysis was reduced under XHC storage with less glucose consumption and lactate generation. Activation levels for Day 14 platelets, while increased, did not prevent response to agonists in vitro, including epinephrine + Adenosine 5‐Diphosphate (EPI/ADP) and thrombin receptor‐activating peptide (TRAP) aggregation. Thromboelastogram (TEG) assessment showed 80% or greater conservation of platelet function for Day 14 xenon stored platelets compared with Day 5 SC platelets.DiscussionPlatelet storage with the Xe/hyperbaric/cold method is a feasible candidate for extension of storage to 14 days based on in vitro characteristics. In vivo recovery and survival studies are indicated. The capability to extend platelet storage to 14 days would make large strides toward resolving issues of platelet outdating for prophylactic use.

Published: August 2022

Abstract
The 1/3 subharmonic resonance response of Duffing oscillator with Coulomb dry friction under foundation excitation is investigated, and the approximate analytical solution of the subharmonic resonance of the system is obtained by using the incremental averaging method. Based on the approximate analytical solution of the primary resonance obtained by the averaging method, the approximate analytical solution of subharmonic resonance is solved by the averaging method according to the incremental equation, and the amplitude–frequency response equation of subharmonic resonance is obtained. It is found that the Coulomb friction affects the amplitude–frequency response of both the primary resonance and subharmonic resonance of the nonlinear dry friction system in the form of equivalent damping. The comparison between the approximate analytical solution and the numerical solution shows that the approximate analytical solutions of the primary resonance and subharmonic resonance are both in very good agreement with the numerical solution. The existence condition of the 1/3 subharmonic resonance for the nonlinear dry friction system is presented, and the stability of the steady-state solution of subharmonic resonance is also judged. Based on the approximate analytical solution, the effects of the nonlinear stiffness and the Coulomb friction on the amplitude–frequency response of resonance and critical frequency of 1/3 subharmonic resonance of the nonlinear dry friction system are analyzed in detail. The analysis results show that the incremental averaging method can effectively obtain the approximate analytical solution in unified form for the subharmonic resonance of nonlinear system with Coulomb friction.
Solution of Unsteady Flow Equations for Nanoscale Heat and Mass Transfer in Diverse Applications
Authors: Sinha Ramlala P. 
Published: August 2022

Abstract
A new innovative stable time-dependent compressible flow solution over the order of nanoseconds is provided here for wide-ranging critically important challenging applications. Specifically, a solution of the highly complex unsteady high speed oscillating compressible flow field inside a cylindrical tube, closed at one end with a piston oscillating at very high resonant frequency at the other end, has been obtained numerically, assuming one-dimensional, viscous, and heat-conducting flow, by solving the appropriate fluid dynamic and energy equations. An iterative implicit finite difference scheme is employed to obtain the solution. The scheme permits arbitrary boundary conditions at the piston and the end wall and allows assumptions for transport properties. In successfully predicting the time-dependent results/data, an innovative simple but stable solution of unsteady fluid dynamic and energy equations is provided here for wide ranging research, design, development, analysis, and industrial applications in solving a variety of complex fluid flow heat transfer problems. The method is directly applicable to pulsed or pulsating flow and wave motion thermal energy transport, fluid-structure interaction heat transfer enhancement, nanoscale heat and mass transfer, diverse range of advanced fluidics, biofluidics/bio-engineering, and fluidic pyrotechnic initiation devices. It can further be easily extended to cover muzzle blasts and high energy nuclear explosion blast wave propagations in one-dimensional and/or radial spherical coordinates with or without including energy generation/addition terms. No other solution exists for such applications.

Authors: Wang C. Y. 
Published: August 2022

Abstract
The fully developed forced convection with H1 and/or H2 conditions in a semi-elliptic duct is studied. Such ducts model conduits attached to a flat surface and etched microfluidic channels. Due to differences in materials, the duct wall may be highly conductive (H1) or poorly conductive (H2) or a mixture of both. This paper presents analytic small aspect ratio asymptotic solutions and tables of Poiseuille and Nusselt numbers for various aspect ratios and boundary conditions.
Coaching With Latour in the Sociomateriality of Sport: A Cartography for Practice
Authors: Maclean Jordan , Allen Justine 
Published: August 2022

While there is increasing recognition that sport is sociomaterial, little is known about what this means for an analysis of coaching practice. This paper develops a cartography of coaching based on an actor–network theory ethnography of two volunteer football coaches’ practices in Scotland. A sociomaterial analysis generates anecdotes that are reordered into five parts: (a) moving from the eleven-a-side game toward a field of practice, (b) delegation, (c) quasi-object, (d) interruptions, and (e) manufacturing. Each part is accompanied with an analytical move inspired by Latourian actor–network theory. Coaching is conceptualized as a field of practice resting on three propositions. The first proposition is that coaches intervene by fabricating passages in practices which are always under construction. The second proposition is that materials and materiality shape practices in ways which can make players more, or less, disciplined. And the third proposition is for a local and situated sociomaterial competence where nonhumans are matters of concern. Coaching with Latour paves the way for a new space in the sociology of sport for studies dedicated to the sociomateriality of sport.

Published: August 2022

BackgroundHomonymous visual field (VF) defects are usually an indicator of serious intracranial pathology but may be subtle and difficult to detect. Artificial intelligence (AI) models could play a key role in simplifying the detection of these defects. This study aimed to develop an automated deep learning AI model to accurately identify homonymous VF defects from automated perimetry.MethodsVFs performed on Humphrey field analyser (24–2 algorithm) were collected and run through an in-house optical character recognition program that extracted mean deviation data and prepared it for use in the proposed AI model. The deep learning AI model, Deep Homonymous Classifier, was developed using PyTorch framework and used convolutional neural networks to extract spatial features for binary classification. Total collected dataset underwent 7-fold cross validation for model training and evaluation. To address dataset class imbalance, data augmentation techniques and state-of-the-art loss function that uses complement cross entropy were used to train and enhance the proposed AI model.ResultsThe proposed model was evaluated using 7-fold cross validation and achieved an average accuracy of 87% for detecting homonymous VF defects in previously unseen VFs. Recall, which is a critical value for this model as reducing false negatives is a priority in disease detection, was found to be on average 92%. The calculated F2 score for the proposed model was 0.89 with a Cohen’s kappa value of 0.70.ConclusionThis newly developed deep learning model achieved an overall average accuracy of 87%, making it highly effective in identifying homonymous VF defects on automated perimetry.

Backgroud/AimOcular involvement in systemic lupus erythematosus (SLE) is often primarily recognised by ophthalmologists rather than internists. This study aims to investigate the incidence and risk factors for the occurrence of posterior ocular ischaemic events (OIE), including retinal vein occlusion (RVO), retinal artery occlusion (RAO) and ischaemic optic neuropathy (ION), in patients with SLE.MethodsA national database in Taiwan was used to identify 24 472 patients newly diagnosed with SLE and 244 720 age-matched and sex-matched controls between 1997 and 2012. New occurrences of OIE and confounding factors were recorded. The Kaplan-Meier method was used to compare the risk of OIE between the two groups. Fixed effect models were applied to evaluate the risk factors for OIE.ResultsThe mean age was 36.24±15.82 years and women accounted for 88.4%. Patients with SLE had significantly increased risk of overall OIE (HR 3.89, 95% CI 3.36 to 4.50, p<0.001) as well as each OIE subtype. End-stage renal disease (ESRD; HR 2.91, 95% CI 2.05 to 4.14, p<0.001), hypertension (HR 1.77, 95% CI 1.21 to 2.58, p=0.003) and congestive heart failure (HR 1.67, 95% CI 1.12 to 2.48, p=0.01) were associated with RVO development. Hypertension (HR 2.89, 95% CI 1.10 to 3.96, p=0.02) and ischaemic stroke (HR 3.58, 95% CI 1.97 to 6.48, p<0.001) had increased risk of RAO. ESRD was associated with ION (HR 3.03, 95% CI 1.41 to 6.51, p=0.004). Intravenous steroid was associated with RVO development (HR 2.54, 95% CI 1.67 to 3.84, p<0.001).ConclusionsSLE increases the risk of developing OIE. Systemic comorbidities and higher dosage of steroid in patients with SLE are associated with severe ocular ischaemic complications.

ObjectivesWomen’s decision-making power is a dimension of empowerment and is crucial for better physical and psychosocial outcomes of mothers. Suchana, a large-scale development programme in Bangladesh, actively provided social interventions on behaviour change communication to empower women belonging to the poorest social segment. This paper aims to assess the impact of the Suchana intervention on various indicators related to women’s decision-making power.Design, setting and participantsThe evaluation design was a cluster randomised pre-post design with two cross-sectional surveys conducted among beneficiary women with at least one child aged <23 months from randomly selected poor or very poor beneficiary households in Sylhet division.Outcome measureDecision-making indicators included food purchases, major household purchases, food preparation, children’s healthcare as well as women’s own healthcare and visiting family and relatives.ResultsOur findings suggest that 45% of women were able to make decisions on food purchases, 25% on major household purchases, 78% on food preparation, 59% on children’s healthcare, 51% on their own healthcare and 43% on visiting family and relatives at baseline in the intervention group, whereas the results were almost the same in the control group. In contrast, at the endline survey, the respective proportions were 75%, 56%, 87%, 80%, 77% and 67% in the intervention group, which were significantly improved when compared with the control group. The prevalence of those outcome indicators were 64%, 41%, 80%, 71%, 68% and 56%, respectively, in the control group. As per multiple logistic regression analysis and structural equation modelling, the Suchana intervention had a substantial influence on the latent variable of women’s decision-making power.ConclusionIn terms of food purchases, major household purchases, children’s healthcare, their own healthcare and visiting family and relatives, the Suchana intervention favourably influenced the decision-making power of rural women living in a vulnerable region of Bangladesh.Trial registration numberRIDIE-STUDY-ID-5d5678361809b.

ObjectiveTo establish the prevalence of long-term and serious harms of medical cannabis for chronic pain.DesignSystematic review and meta-analysis.Data sourcesMEDLINE, EMBASE, PsycINFO and CENTRAL from inception to 1 April 2020.Study selectionNon-randomised studies reporting on harms of medical cannabis or cannabinoids in adults or children living with chronic pain with ≥4 weeks of follow-up.Data extraction and synthesisA parallel guideline panel provided input on the design and interpretation of the systematic review, including selection of adverse events for consideration. Two reviewers, working independently and in duplicate, screened the search results, extracted data and assessed risk of bias. We used random-effects models for all meta-analyses and the Grades of Recommendations, Assessment, Development and Evaluation approach to evaluate the certainty of evidence.ResultsWe identified 39 eligible studies that enrolled 12 143 adult patients with chronic pain. Very low certainty evidence suggests that adverse events are common (prevalence: 26.0%; 95% CI 13.2% to 41.2%) among users of medical cannabis for chronic pain, particularly any psychiatric adverse events (prevalence: 13.5%; 95% CI 2.6% to 30.6%). Very low certainty evidence, however, indicates serious adverse events, adverse events leading to discontinuation, cognitive adverse events, accidents and injuries, and dependence and withdrawal syndrome are less common and each typically occur in fewer than 1 in 20 patients. We compared studies with <24 weeks and ≥24 weeks of cannabis use and found more adverse events reported among studies with longer follow-up (test for interaction p<0.01). Palmitoylethanolamide was usually associated with few to no adverse events. We found insufficient evidence addressing the harms of medical cannabis compared with other pain management options, such as opioids.ConclusionsThere is very low certainty evidence that adverse events are common among people living with chronic pain who use medical cannabis or cannabinoids, but that few patients experience serious adverse events.

ObjectiveTo provide an overview of the use of and evidence for eConsult in correctional facilities worldwide.DesignScoping review.Data sourcesThree academic databases (MEDLINE, Embase and CINAHL) were searched to identify papers published between 1990 and 2020 that presented data on eConsult use in correctional facilities. The grey literature was also searched for any resources that discussed eConsult use in correctional facilities. Articles and resources were excluded if they discussed synchronous, patient-to-provider or unsecure communication. The reference lists of included articles were also hand searched.ResultsOf the 226 records retrieved from the academic literature search and 595 from the grey literature search, 22 were included in the review. Most study populations included adult male offenders in a variety of correctional environments. These resources identified 13 unique eConsult services in six countries. Six of these services involved multiple medical specialties, while the remaining services were single specialty. The available evidence was organised into five identified themes: feasibility, cost-effectiveness, access to care, provider satisfaction and clinical impact.ConclusionsThis study identified evidence that the use of eConsult in correctional facilities is beneficial and avoids unnecessary transportation of offenders outside of the facilities. It is feasible, cost-effective, increases access to care, has an impact on clinical care and has high provider satisfaction. Some gaps in the literature remain, and we suggest further research on patient satisfaction, enablers and barriers to implementation, and women, youth and transgender populations in this setting to inform service providers and stakeholders. Despite some gaps, eConsult is evidently an important tool to provide timely, high-quality care to offenders.
