Uncertainty and Planning: Cities, Technologies and Public Decision-Making
Authors: Moroni Stefano , Chiffi Daniele 
Published: January 2022

AbstractDecision-making under uncertainty is sometimes investigated as a homogeneous problem, independently of the type of decision-maker and the level and nature of the decision itself. However, when the decision-maker is a public authority, there immediately arise problems additional to those that concern any other (private) decision-maker. This is not always clearly recognised in orthodox discussions on decisions under conditions of uncertainty. This article investigates the methodological, strategic and procedural challenges of taking public decisions in such conditions. It focuses mainly on decisions involving urban contexts, such as planning decisions regarding land use and building transformations, by trying to develop some pioneering research studies in this field.
Moral Uncertainty in Technomoral Change: Bridging the Explanatory Gap
Authors: Nickel Philip J. , Kudina Olya , van de Poel Ibo 
Published: January 2022

AbstractThis paper explores the role of moral uncertainty in explaining the morally disruptive character of new technologies. We argue that existing accounts of technomoral change do not fully explain its disruptiveness. This explanatory gap can be bridged by examining the epistemic dimensions of technomoral change, focusing on moral uncertainty and inquiry. To develop this account, we examine three historical cases: the introduction of the early pregnancy test, the contraception pill, and brain death. The resulting account highlights what we call “differential disruption” and provides a resource for fields such as technology assessment, ethics of technology, and responsible innovation.

Published: January 2022

Background Rewarming on cardiopulmonary bypass (CPB) is associated with increased metabolic demands; however, it remains unclear whether cerebral autoregulation is affected during this phase. This RCT aims to describe the effects of 20% supranormal, compared to normal CPB flow, on monitoring signs of inadequate perfusion, oxygenation, and disturbed cerebral autoregulation, during the rewarming phase of CPB. Method Thirty two patients scheduled for coronary artery bypass grafting were allocated to a Control group ( n = 16) receiving a CPB pump flow corresponding to preoperatively measured cardiac output, and an Intervention group ( n = 16) receiving the corresponding CPB pump flow increased by 20% during rewarming. Cerebral Oximetry Index (COx) was calculated with the aid of Near Infrared Spectroscopy. Results Twenty five patients were included in the data. Results show a median COx value of 0.0 (IQR −0.33–0.5) (Control) and 0.0 (IQR −0.15–0.25) (Intervention), respectively; p = .85 with individual variations within groups. The median cerebral perfusion pressure (CPP) was 55 (52–58) (Control) and 61 (54–66) mmHg (Intervention); p = .08. No significant difference in rSO2 values was observed between the groups (58.5% (50–61) versus 64% (58–68); p = .06). Conclusion The present study showed no difference between increased and normal CPB pump flow with respect to cerebral autoregulation during rewarming. Large variations in cerebral autoregulation were seen at individual level.

Objective To investigate the potential factors affecting methicillin-resistant Staphylococcus aureus (MRSA) colonization and infection in patients with human immunodeficiency virus (HIV) infection. Methods A systematic search of publications listed in electronic from inception up to August 2020 was conducted. A random-effects model was used to calculate odds ratio (OR) with 95% confidence interval (CI). Results A total of 31 studies reporting 1410 MRSA events in 17 427 patients with HIV infection were included. Previous hospitalization (OR 1.80; 95% CI 1.37, 2.36), previous antibiotic therapy (OR 2.69; 95% CI 2.09, 3.45), CD4+ count (OR 1.79; 95% CI 1.41, 2.28), Centers for Disease Control and Prevention classification of stage C (OR 2.66; 95% CI 1.80, 3.93), skin lesions (OR 2.02; 95% CI 1.15, 3.55), intravenous device use (OR 2.61; 95% CI 1.59, 4.29) and an MRSA colonization history (OR 6.30; 95% CI 2.50, 15.90) were significantly associated with an increased risk of MRSA colonization and infection. Antiretroviral therapy (OR 0.71; 95% CI 0.50, 0.99) and current antibiotic use (OR 0.13; 95% CI 0.05, 0.32) were significantly associated with a reduced risk of MRSA colonization and infection. Conclusion MRSA colonization and infection in HIV-infected patients is associated with a number of risk factors.
Circ_0006220 promotes non-small cell lung cancer progression via sponging miR-203-3p and regulating RGS17 expression
Authors: Wang Shaochun , Zhang Chengcheng , Chen Ruilin 
Published: January 2022

Background Lung cancer is the most common malignancy, and its mortality ranks first among malignancies. Non-small cell lung carcinoma (NSCLC) is the most common pathological subtype of lung cancer. It is reported that circular RNAs (circRNAs) feature prominently in the occurrence and metastasis of NSCLC. Purpose This study aims to decipher the biological functions of circ_0006220 in NSCLC and the underlying mechanism. Methods The microarray data (GSE101586) were downloaded from the Gene Expression Omnibus database, and differentially expressed circRNAs in NSCLC tissues were screened using the GEO2R tool. Quantitative real-time polymerase chain reaction was used for detecting the expression of circ_0006220, miR-203-3p, and regulator of G-protein signaling 17 (RGS17) mRNA in NSCLC tissues and cells. The connection between circ_0006220 expression and clinicopathological indicators was analyzed through the chi-square test. EdU and cell counting kit-8 assays were carried out to detect cell growth. Cell migration and invasion were detected by transwell assays. Bioinformatics was used to predict, and RNA immunoprecipitation assay and dual-luciferase reporter gene assay were conducted for verifying, the targeted relationship among circ_0006220, miR-203-3p, and RGS17. Results The expression of circ_0006220 was elevated in NSCLC cells and tissues, and high circ_0006220 expression was significantly associated with unfavorable clinicopathological indicators. In addition, it was revealed that circ_0006220 overexpression facilitated NSCLC cell growth, migration, and invasion, whereas knocking down circ_0006220 had contrary effects. Furthermore, miR-203-3p was identified as a downstream target of circ_0006220, and circ_0006220 could sponge miR-203-3p; RGS17 was identified as a downstream target of miR-203-3p and was positively modulated by circ_0006220. Conclusions Circ_0006220 up-regulates RGS17 expression by adsorbing miR-203-3p to promote NSCLC development.
Severe thrombotic events associated with pre-procedural interruption of anticoagulation in systemic lupus erythematosus with secondary antiphospholipid syndrome: Cases and literature review
Authors: Anderson Meghan , Belmont H. Michael 
Published: January 2022

Background The American College of Chest Physicians (ACCP) and National Institutes for health and care Excellence in the United Kingdom (NICE) recommend that patients who are high risk for thrombotic events but require cessation of oral anticoagulation with warfarin, due to bleeding risk of a planned procedure, undergo bridging therapy with heparin. However, those conditions which are considered high risk are not universal, nor do guidelines differentiate between low molecular weight heparin (LMWH) and unfractionated heparin. Triple positive antiphospholipid syndrome (APS) is a thrombophilic state with a very high risk for thrombotic events during periods of anticoagulation cessation. Patients with secondary antiphospholipid syndrome in the setting of SLE may be at an even greater risk of thrombotic events during the perioperative period. Purpose Along with a review of the literature for perioperative management in APS we present three cases of triple positive secondary APS in systemic lupus erythematosus (SLE) patients who had severe thrombotic complications after cessation of their oral anticoagulation despite being bridged with LWMH. Conclusion Given the severity and rapidity of thrombotic complications with low molecular weight heparin bridging, we propose that all patients with triple positive APS, especially secondary APS with SLE should undergo bridging therapy with intravenous UFH to reduce time without anticoagulation and minimize risk of thrombotic complications. Furthermore, we propose that NICE include APS in the list of medical conditions which are high risk for thrombotic complications and require bridging therapy.

Background: Currently, fresh fruit juices are widely consumed as a drink worldwide due to their nutritional values and health benefits. Fresh fruit juices are an important source of nutrients, vitamins, and fibers that are important for human health. Fruit juices are nutritious and perishable food that can serve as an ideal medium for the growth and multiplication of pathogenic microorganisms. Therefore, this study aimed to determine the bacteriological quality of locally prepared fresh fruit juices sold in juice houses of eastern Ethiopia from 4 April to 12 June 2020. Methods: A cross-sectional study was used that included administrative questionnaires and laboratory-based investigations. A total of 78 fruit juice samples that include mango, avocado, papaya, and mixed juices were collected aseptically from the juice houses. The most probable number method was used to determine the total coliform, fecal coliform and Escherichia coli. The pour plate count method was used to determine the total viable bacteria count. Finally, data were analyzed using descriptive statistical tests that included analysis of variance, Chi-square and Fisher’s exact tests. A P-value of .05 was considered as a cut-off point for statistical significance. Results: Among the 78 juice samples analyzed, 85.9% of the samples had total viable bacterial count, 64.1% had total coliform count, 60.3% had fecal coliform, and 33.3% of the samples had Escherichia coli higher than the maximum permitted level of Gulf standard 2000. The study found a significant association between bacterial contamination and educational status (χ2 = 31.663), training in food hygiene and safety (χ2 = 23.04), method of fruit preservation (χ2 = 17.98), place to keep the juice (χ2 = 13.7), action done with the juice gone bad (χ2 = 12.78), frequency of cleaning materials used to keep the juice (χ2 = 12.78), type of dish washing (χ2 = 19.75), availability of hand washing equipment (χ2 = 12.78), and types of waste receptacles (χ2 = 26.25) ( P-value <.05) (Table 5). Conclusion: In general, majority of fruit juice samples were contaminated with one or more different bacteria species higher than the maximum permitted level. Furthermore, the study found the association between bacterial contamination and other variables such as hygienic and safety conditions. Therefore, the implementation of adequate hygiene and safety practices is very important to prevent the consumption of contaminated fruit juices, which leads to foodborne illness.

Introduction: Citrobacter spp. is an opportunistic bacteria that have been recognized as significant pathogens in patients with underlying diseases or immunocompromised status. The aim of this study was to identify extended-spectrum β-lactamases in clinical isolates of Citrobacter spp. Methods: This cross-sectional study was conducted at Hospital Central “Dr. Ignacio Morones Prieto” in San Luis Potosi, Mexico. Nineteen isolates of Citrobacter spp. were obtained from clinical specimens between April to December 2015. Four isolates were resistant to third-generation cephalosporins. The presence of genes encoding ESBL ( blaCTX-M-15, blaTEM-1, blaVEB-1, blaSHV, and blaPER-1) was analyzed by PCR. For this purpose, plasmid DNA was extracted and horizontally transferred to recipient E. coli Top 10. Results: blaCTX-M-15 and blaVEB-1 genes were detected in Citrobacter freundii and Citrobacter sedlakii, whereas blaPER-1 gene was identified in 1 isolate of Citrobacter freundii. In contrast, blaSHV gene was not detected in any isolate. One strain carried blaCTX-M-15, blaTEM-1, blaVEB-1, and blaPER-1 genes, most in a 275-kb plasmid. Conclusion: This study shows the presence of different types of ESBL in clinical isolates of Citrobacter freundii and Citrobacter sedlakii, which confer resistance to broad-spectrum β-lactams. The plasmid identified in this study harboring ESBL genes could play an important role in the dissemination of antibiotic resistance.

Published: January 2022

Respiratory aerosol particles carrying the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) are a primary cause of the long-distance infection, and insufficient ventilation systems make building occupants highly prone to the coronavirus disease-2019 (COVID-19). As a preventive measure of the aerosolized viable SARS-CoV-2 suspension in building space, we seek to propose an optimal design of the upper-room/drop-ceiling aeration grid system generating vertical laminar airflow (VLAF) as an aerosol barrier. On a test plan (6.1 × 4.7 m) representing the standard hospital patient room in South Korea (a 2.7 m-height room of 77.4 m3 in volume), we investigated the air-terminal size, spacing and air speed that shape uniform downflow of fresh air, minimizing horizontal spread. Our simulation results using the Taguchi method and computational fluid dynamics (CFD) in presence of indoor human expiration indicated that a steady vertical air supply of 0.3 m/s through 0.04m-diameter air diffusers deployed by 0.5 m spacing is the most effective to form VLAF. Physical particle detection tests at the height of 1.5 m in mockup setting of the optimal system design, revealed that expiratory aerosols produced by a single person were almost entirely removable in 20 s. Investigations also confirmed that the proposed design could minimize stagnant airflow regions and would potentially satisfy the indoor air-speed condition for occupant thermal comfort.

Published: January 2022

One of the primary constituent layers of fire protective clothing is a flame-retardant, waterproof and breathable moisture barrier, which permits the outward transfer of perspiration from the firefighter’s body, while barring the inward entry of water. The introduction of a chemical and biological resistant functionality can greatly enhance the overall applicability of fire protective clothing. In the present work, a chemical & biological resistant waterproof breathable flame retardant moisture barrier fabric was prepared by laminating a biaxially stretched microporous expanded polytetraflouroethylene (ePTFE) membrane with Activated Carbon Fabric using a hot melt reactive breathable polyurethane adhesive. The developed laminate was found to exhibit an excellent balance of waterproofness (23 kPa) and breathability, which was quantified in terms of water vapour transmission rate (WVTR) and water vapour resistance (Ret). High values of WVTR, 1.1025 × 104 ± 9.8×101 g/m2/day complimented with exceptionally low values of Ret, 2.9 m2Pa/W are indicative of its high degree of breathability. Vertical flammability tests clearly revealed the exceptional flame resistance offered by the laminate, where after-flame, after-glow or melt-dripping was not observed and the char length was ∼4.2 cm. Further, the laminate exhibited requisite degree of protection against biological and chemical warfare (CW) agent with no breakthrough of the CW agent being perceived within the time frame of 24 h. The excellent combination of flame retardancy, breathability, waterproofness, chemical and biological protection, bestows the laminate excellent potential for usage as moisture barrier in fire protective clothing applications.

Authors: Jamshed Ayesha , Jabeen Qaiser 
Published: January 2022

Background: Mentha piperita L. (peppermint) is one of the most widely consumed medicinal herbs that has gained attention from food and pharmaceutical industries due to its distinct aroma and taste. Purpose: Present study was aimed to rationalize the traditional use of peppermint in urolithiasis and to explore its possible underlying mechanism. Research Design: The aqueous methanolic crude extract of Mentha piperita (Mp.Cr) was assessed for phytochemical constituents and antioxidant activity. In vitro crystallization assays were performed to determine the inhibitory effects of Mp.Cr against crystal nucleation, aggregation and growth. In vivo urolithiasis model was developed in rats by the administration of ammonium chloride and ethylene glycol in drinking water. The antiurolithic effects of Mp.Cr were evaluated by analyzing kidney homogenate, biochemical and histological parameters. Results: HPLC analysis showed the presence of epicatechin, quercetin, gallic acid, syringic acid, kaempferol, caffeic acid and coumaric acid. The maximum quantity of quercetin equivalent flavonoid and gallic acid equivalent phenolic content was found to be 63.73 ± .24 mg QE/g and 43.76 ± .6 mg GAE/g of Mp.Cr, respectively. Mp.Cr significantly normalized urinary and serum biochemistry, similar to the standard cystone treatment. Conclusions: The current study validated the preventive and curative potential of Mp.Cr against urolithiasis and justified its traditional use in kidney stone disease.

Published: January 2022

Objective The literature suggests that heparin reversal with protamine in transcarotid arterial revascularization (TCAR) decreases postoperative bleeding complications without an increase in stroke or death. However, the dosing of protamine in TCAR has not yet been evaluated. We aimed to evaluate our experience with intraoperative heparin reversal with protamine. Methods This was a single-center, retrospective, observational study that evaluated the heparin and protamine doses used during TCAR. All adult patients who underwent TCAR between 9/1/2019 and 4/2/2021 were included. Demographic data was obtained from the Vascular Quality Initiative and protamine/heparin doses were obtained from a chart review. Multivariate logistic regression models were used to assess the association between the protamine/heparin dose ratio and other variables. Results Sixty-two patients were included. The average protamine/heparin dose ratio used was 0.96 ± 0.12 mg/U; seven had a ratio less than 0.8 mg/U, and one was greater than 1.2 mg/U. Two patients experienced bleeding complications, which were managed non-operatively. No patient with a protamine/heparin ratio greater than 0.8 mg/U had postoperative bleeding. Postoperative bradycardia was observed in 32.3% of patients and hypotension in 35%, with 19% requiring vasopressors. No relationship was identified between the protamine/heparin ratio and bleeding, bradycardia, or hypotension. No 30-day myocardial infarction, stroke or death occurred. Conclusions We identified a near 1:1 ratio of a protamine/heparin dosing regimen for the reversal of heparin during TCAR, with postoperative bleeding complications similar to those reported in the literature. However, patients who received a lower protamine/heparin ratio did not experience bleeding complications. In the era of protamine shortages, a future larger-scale study is needed to evaluate the impact of a lower protamine dose on postoperative complications.
A prospective randomised comparative study of dynamic, static progressive and serial static proximal interphalangeal joint extension orthoses
Authors: Glasgow Celeste , Ballard Emma 
Published: January 2022

Introduction Many different types of proximal interphalangeal (PIP) joint extension orthoses exist, yet evidence guiding orthosis choice is largely theoretical. The primary aim of this study was to evaluate the clinical effectiveness of three different PIP joint extension orthoses, over 4 weeks of treatment. Secondly, we aimed to explore the relationship between an abbreviated version of the Weeks test (WT) assessment of joint stiffness, and treatment outcome. Lastly, we wished to better understand participants’ satisfaction with orthotic treatment. Methods Using a randomised comparative study design, 61 participants were allocated to a serial static, dynamic or static progressive orthosis, 50 had follow-up data. Blinded assessment of function was completed before and after 4 weeks of orthotic intervention and a standardised therapy program. Participants were blinded to alternative groups. Results Baseline active PIP extension ranged from 14° to 65°. The average improvement in active PIP extension was −9.1° (95% CI −11.0°, −7.1°). There were no statistically significant differences in outcome between the three orthoses groups. However, a trend was observed with greater improvement in active extension for those in the dynamic Capener (−11.5°) compared to the static progressive belly gutter (−7.3°) or serial cast (−8.7°) groups, with less total end range time required. The abbreviated WT was significantly associated with improvement in active extension ( p = 0.001). Participants reported a high degree of satisfaction with their orthosis regardless of type. Conclusions No single orthosis demonstrated statistically greater effectiveness, although the dynamic Capener orthosis appeared more efficient. The abbreviated WT is associated with treatment outcome.

Published: January 2022

Summary The Zephyr (PulmonX Inc., Redwood, CA) endobronchial valve (EBV), predominantly designed for lung volume reduction in emphysema, can also be used to close a spontaneous or post-operative prolonged air leak (PAL). We describe a previously unreported complication of cutaneous migration of an EBV, inserted for management of a PAL from a postoperative bronchopleural fistula (BPF), in a 62-year-old male following a right upper lobe posterior-apical (S1,2) segmentectomy. His PAL resulted in a chronic empyema which failed to respond to surgical debridement, anterior cavernostomy and pectoral myoplasty. Bronchoscopic closure of the air leak by EBV insertion resulted in clinical improvement but there was a residual chronic wound sinus through which the patient reported protrusion of a foreign body that was causing irritation. It was the EBV. We hypothesise that the BPF healed beneath the EBV causing it to dislodge but its route to the skin remains a mystery.
