Authors: Hai Ri
Published: July 2022

National costume contains rich patterns and patterns with national characteristics, which is an important part of the study of national costume culture. Neither the traditional protection of national costumes nor the early digital protection can clearly and effectively preserve the details of national costumes, which is not conducive to the development and research of national costume culture. The development of image processing technology provides new technical support for the protection and inheritance of national costumes. This paper proposes the application of spatial neighborhood fuzzy c-means algorithm in 3D image segmentation of national clothing. Based on the traditional fuzzy c-means algorithm, combined with spatial information and gray information, a 3D image segmentation model based on spatial neighborhood fuzzy c-means is constructed. The experimental results show that the 3D image segmentation model based on spatial neighborhood fuzzy c-means has faster convergence speed and better algorithm performance than the improved fuzzy c-means algorithm and has better image segmentation effect in different noise levels. In the 3D image segmentation of national costumes, more detailed information can be retained on the basis of maintaining high accuracy and effect.

Published: July 2022

With the continuous progress of the times, people’s economic level has also improved, and they have more specific requirements for their own quality of life. At present, looking at the domestic health industry, its development is far from meeting people’s expectations. In recent years, the state has advocated the construction of a number of sports characteristic small towns with national participation, beautiful ecology, industrial integration, and distinctive characteristics. The Guangxi government responded to the national initiative and actively supported it in policy, introduced investment funds, and established eight sports characteristic small towns, which are in good condition of development. This study takes this as the research object, through consulting various literatures, data material, and visiting experts and scholars, actually checks the development of these eight characteristic small towns, and sorts out and analyzes the collected information on its natural resources, humanistic characteristics, and diversified industrial integration. It provides a theoretical basis for the subsequent design, planning, and practice of characteristic small town. After the overall normative construction and taking the normative effect as the empirical evaluation standard, it has effectively promoted the vigorous development of small towns with sports characteristics in China.
A High Effective Acid System to Stimulate Sandstone Reservoirs
Authors: Li Bin
Published: July 2022

Mud acid is regularly applied to recover or increase permeability of sandstone reservoir. However, due to its rapid reacting rate and heterogeneous displacement, the stimulation effect of conventional mud acid is relatively limited in sandstone formations. For mud acid, it is important to choose proper chemical additives to retard reaction rate and make it distributed homogenereously in formation. To overcome these shortcomings of mud acid, a new proprietary mud acid system has been developed for sandstone formations stimulation. The new system is composed of 2.0% multichemical solutions (MCS) +6.5%HCl+1.5% HF, and the combined solution contains nonionic surfactant, clay stabilizer, and dispersant which were specifically formulated. Core flooding experiments were conducted with the high effective mud acid; meanwhile, XRD and SEM analysis were performed before/after the core flooding tests. Retarded tests were also conducted for the new mud acid reacting with sandstone samples. Treatments with ten pores volume of the new high effective mud acid system were found to increase permeability of sandstone core approximately three times of its initial permeability. From the results of SEM and XRD analysis, most of clays were dissolved, and permeability was increased after core flooding by this new mud acid solution. On the basis of acidizing theory, the reaction retarded mechanism was explained about the new composite mud acid. Other properties of the new composite mud acid were also discussed. In comparison of conventional mud acid, the new composite mud acid can retard acidizing reaction rate and distribute evenly in formation; therefore, it can extend acidizing penetration and stimulate sandstone formation thoroughly. The new composite mud acid is more compatible and desirable than conventional mud acid, and it will be applied extensively for sandstone matrix stimulation.

Authors: Qin Dongjie , Sun Baohua
Published: July 2022

This paper presents a wideband monopole antenna with distributed matching structures operating on VHF/UHF bands. The antenna consists of a slim rectangular metal strip with a T-type slot etched on the upper half, two rectangular slots on the lower half, and two rectangular plates soldered with the bottom end of the main strip. The antenna is installed on a metal case which serves as ground. To achieve a wide bandwidth, an impedance matching network consisting of the distributed structures, which are composed of two metal plates and a metal thin strip, is devised and integrated with the main radiating strip. The T-type slot near the top tip of the main strip is used for the miniaturization of the antenna. The proposed antenna is fabricated and measured, and the measured results are in good agreement with the simulated results. The sizes of the proposed antenna and the case are 0.19λmax × 0.014λmax and 0.17λmax × 0.1λmax × 0.034λmax, respectively. The operating bandwidth is from 203.7 to 516.9 MHz (2.54 octaves) with the condition of VSWR ≤ 3 : 1. This antenna has a slim structure, a wide bandwidth covering partially VHF and UHF bands, and omnidirectional radiation patterns, so it can be the candidate for the applications of backpacked radio stations in military communication scenarios.

2D nanomaterials‐based heat transfer fluids show excellent thermal properties due to their large specific surface area; hence, they find large‐scale applications in automobile industries and cooling processes. Therefore, it is very essential to study the environmental and economic aspects of these 2D nanomaterial‐based nanofluids. In this review, we have discussed the environmental impact of 2D nanomaterial‐based heat transfer nanofluids under various conditions. The environmental impact analysis of these materials has shown excellent capability in reducing the energy consumption for heat transfer operations. Moreover, the possibility of nanomaterials and base fluid recovery makes it a sustainable alternative. In addition, health risk assessment on humans, cytotoxicity, and life cycle analysis have also been explored. The price‐performance index has been successfully used to study the economic impact of 2D nanomaterial‐based heat transfer fluids. The overall economic impact of 2D nanomaterial‐based heat transfer nanofluids provides an optimistic perspective over conventional heat transfer fluids. Moreover, graphene production, market trend, and commercialization obstacles were also discussed.

Authors: Hu Qinlong , Fan Yimin
Published: July 2022

In order to improve the efficiency of a logistics cycle robot picking up goods, a path planning algorithm based on artificial intelligence was proposed. After analyzing the particle swarm optimization algorithm, the particle swarm optimization algorithm is optimized and improved and the path planning of a single robot is obtained. On this basis, a multipopulation particle swarm optimization (CMMPPSO) algorithm is proposed. The results show that the JMPOPSO algorithm is more accurate than the BPSO algorithm and the maximum fitness optimized by the BPSO algorithm is 1.59, while the maximum fitness optimized by the JMPOPSO algorithm is 1.98. The path optimized by the CMMPPSO algorithm based on JMPOPSO is better than that optimized by the CMMPPSO algorithm based on BPSO, shortening by about 25% and shortening the time by about 30. Simulation experiments verify the effectiveness of the CMMPPSO algorithm.

Authors: Jiang Jiahui , Liu Yuqing , Xu Chaozheng , Shen Hanting
Published: July 2022

In order to adapt to the development of the industrial Internet of Things, the relationship between the internal components of electromechanical equipment is getting closer and closer, such as motor bearings. Nowadays, timely diagnosis of motor bearing faults is urgently needed. Most traditional methods for motor bearing fault diagnosis use a single learner and emphasize the role of feature extraction, which usually requires a large amount of sample support and computer runtime to obtain satisfactory performance. In this article, the Bayesian optimized decision tree with ensemble classifiers after feature extraction of the original data is finally proposed which has good performance. We use multiple feature extraction to establish the feature matrix and construct a decision tree model with the ensemble method for AdaBoost and a Bayesian optimized decision tree model with ensemble classifiers to conduct experiments on the accuracy, prediction speed, etc., of the model. We derived four sets of experimental data. The results show that the optimal method is the Bayesian optimized decision tree with ensemble classifiers after feature extraction. The accuracy of this method is as high as 99.9%. At the same time, unlike previous studies, we found in our study that feature extraction does not improve the accuracy of diagnosis for the decision tree with ensemble method for AdaBoost and there is a precipitous decline. In the industrial Internet of Things, the conclusion can improve certain reference value for the future fault diagnosis of motor bearings.

Published: July 2022

Background. Abnormal proliferation of vascular smooth muscle cells (VSMCs) is an important cause of vascular stenosis. The study explored the mechanism of inhibition of vascular stenosis through the molecular mechanism of smooth muscle cell phenotype transformation. Methods. Coronary heart disease-related genes were screened by bioinformatics, and the target genes of miR-654-5p were predicted by dual-luciferase method and immunofluorescence method. miR-654-5p mimic stimulation and transfection of TCF21 and MTAP into cells. SonoVue microbubble sonication was used to deliver miR-654-5p into cells. Cell proliferation, migration, and invasion were detected by CCK-8, wound scratch, and Transwell. HE and IHC staining were performed to study the effect of miR-654-5p delivery via SonoVue microbubble ultrasound on vessel stenosis in a model of arterial injury. Gene expression was determined by qRT-PCR and WB. Results. TCF21 and MTAP were predicted as the target genes of miR-654-5p. Cytokines induced smooth muscle cell proliferation, migration, and invasion and promoted miR-654-5p downregulation; noticeably, downregulated miR-654-5p was positively associated with the cell proliferation and migration. Overexpression of TCF21 promoted proliferation, invasion, and migration, and mimic reversed such effects. miR-654-5p overexpression delivered by SonoVue microbubble ultrasound inhibited proliferation, migration, and invasion of cells. Moreover, in arterial injury model, we found that SonoVue microbubble ultrasound transmitted miR-654-5p into the arterial wall to inhibit arterial thrombosis and stenosis, while TCF21 was inhibited. Conclusion. Ultrasound delivery of miR-654-5p via SonoVue microbubbles was able to inhibit arterial thrombosis and stenosis by targeting TCF21.

. The formulas are degraded and compared. Meanwhile, the influences of stress diffusion, increased load, matric suction, intermediate principal, and lateral pressure coefficient are conducted on the bearing capacity of unsaturated soft soil foundations with hard crust. The results show that the critical edge load and critical load increased, and the stress diffusion coefficient decreased with the increase of the ratio of elastic modulus between hard crust and soft soil. The bearing capacity of soft soil foundation increased with the consideration of the stress diffusion and closure effect of hard crust. The effect of matric suction is remarkable, and the critical edge load and critical load linearly increase with the increase of low matric suction and variate with the dual influence of high matric suction. The bearing capacity of unsaturated soft soil foundation is obviously higher than that of saturated soil. The critical edge load and critical load increased with the increase of intermediate principal stress and lateral pressure coefficient. The triple-shear unified solution for bearing capacity of unsaturated soft soil foundation with hard crust contains different solutions under various working conditions, which has important theoretical significance and widely engineering application.

Published: July 2022

The experimental research on heat transfer characteristics is an ever-ending scheme since the life of all thermoelectronic devices relies on the effective management of thermal energy. In some cases, the gradient of temperature for heat transfer is to be minimum to avoid energy loss, but also there are numerous applications where the requirement of heat transfer to be maximum and could be achieved with a higher temperature difference between the heat transfer medium. In our current research, distilled water-ethylene glycol heat transfer fluid (HTF) was tested with different inlet mass flow rates and temperature as the hot fluid. Atmospheric air was chosen as the cold fluid. The natural convection heat transfer rate between hot and cold fluid streams was analyzed with and without the generation of micronanobubbles in the hot fluid. It was observed that compared to the base heat transfer fluid, the nanobubbles heat transfer fluid resulted in a 10–12% increase in heat transfer rate at hot fluid inlet temperatures of 28°C, 30°C, 32°C, 34°C, and 36°C. The method of generation of nanobubbles in HTF and their behavior are also highlighted.

Published: July 2022

The crack propagation evolution of carbonaceous mudstone under the action of dry-wet cycles is an important cause of the unstable failure of this type of slope. This paper attempts to reveal the evolution mechanism of mesocrack and macrocrack propagation in carbonaceous mudstone under the action of dry-wet cycles from chemical, physical, and mechanical perspectives. Firstly, the soaking solution of carbonaceous mudstone during the dry-wet cycles was extracted for an ion concentration test to analyze the chemical reactions of carbonaceous mudstone. Then, CT scans were performed on the carbonaceous mudstone samples to study the changing pattern of mesostructure of carbonaceous mudstone during the dry-wet cycles. In the end, the mechanical properties and failure characteristics of carbonaceous mudstone after dry-wet cycles were studied by triaxial compression tests. The results showed that chemical reactions such as calcite dissolution, potassium feldspar hydrolysis, and sodium feldspar hydrolysis occurred during the dry-wet cycle of carbonaceous mudstone. Affected by the dry-wet cycles, the mesostructure of the carbonaceous mudstone gradually changed from face-face contact and edge-face contact to edge-corner contact and corner-corner contact, and the interlayer flake structure was opened and was locally curled and fractured. With the increase in the number of dry-wet cycles, the failure characteristic of carbonaceous mudstone transformed from tensile failure to shear failure, the failure surface of carbonaceous mudstone was deflected from 90° to 60°, and the crack propagation path of carbonaceous mudstone became more complicated. The chemical reaction of carbonaceous mudstone minerals during the dry-wet cycle is an important reason for the initiation and development of pores. The dry-wet cycle aggregates the propagation of mesocracks and structural disorder, transforming the uniform stress state of the rock mesostructure to the concentrated stress state, which is the important reason for the macrocrack propagation evolution of carbonaceous mudstone.

Background. The study aimed to evaluate the safety and efficiency of the saphenous nerve plus selective tibial nerve block combined with general anesthesia in total knee replacement surgery (TKRS). Methods. Sixty-four patients who underwent unilateral TKRS between October 2019 and June 2020 were selected as study subjects. All patients were divided into the control and observation groups using the random number table method, with 32 patients in each group. Conventional general anesthesia was performed preoperatively in both groups. The control group was given an ultrasound-guided saphenous nerve block before anesthesia induction, and the observation group was given a selective tibial nerve block on the basis of the control group. The dosage of general anesthetic drugs, recovery time from general anesthesia, hemodynamic index, inflammatory response, postoperative analgesic effect, and adverse reaction rate were compared between the two groups. Results. Compared with the control group, the total amount of propofol and remifentanil used in the observation group was significantly less (

The typical solar still with internal and exterior heat transfer was used to test the impact of mixing various colours into the basin water. This is well-known that enhancing distillation involves adding black dye to basin water. Identical design parameters create two single-slope basin-type solar stills (effective area 0.5 m2). This study conducted experiments to add black, green, blue, and red dyes to basin water during the winter for 24 hours. For more than a month, the amount of distilled water recovered per hour, with varying temperatures and solar activity (May 2021). This research aims to (i) examine the effect of various dyes with basin water on the internal and external heat transfer and performance of the system and (ii) study the effect of adding dyes into the basin water on increasing energy balance by the solar system. This is indicated by the fact that the introduction of colours into the basin water has a major impact on external and interior heat transfer. The evaporation, radiation, and heat transfer rate from liquid to glass significantly impact how well the filtration system works.

A Study on the Adoption of Blockchain for IoT Devices in Supply Chain
Authors: Baig Muhammad Anas , Ali Sunny Danish , Alqahtani Abdullah , Alsubai Shtwai , Binbusayyis Adel , Muzammal Muhammad
Published: July 2022

The integration of blockchain and IoT enables promising solutions in decentralized environments in contrast with centralized systems. The blockchain brings forth features such as fault tolerance, security, and transparency of the data in IoT devices. As there is requirement of consensus among the network nodes to agree on a single-state-of-ledger, nonetheless, the extensive computational requirement for the consensus protocol becomes a limitation in resource-constrained IoT devices with limited battery, computation, and communication capabilities. This study proposes an empirical approach on the adoption of blockchain in a supply chain environment. Furthermore, a modified version of the Raft consensus protocol is proposed for use in supply-chain environment on the permissioned blockchain Hyperledger. In Raft consensus protocol, each transaction is directed to the leader node that transmits it to the follower nodes, making the leader node the bottleneck thus inhibiting the scalability and throughput of the system. This also results in high latency for the network. The modified RAFT consensus protocol (mRAFT) is based on the idea of utilizing the idle follower nodes in disseminating the vote requests and log replication messages. A detailed empirical evaluation of the solution built on Hyperledger Caliper is performed to demonstrate the applicability of the system. The improved workload division on the peers boosts the throughput and latency of the system in ordering service that enhances the overall efficiency of the system.

Published: July 2022

This article proposes an edge-based denoising algorithm to restore the original image, which is highly degraded by the salt and pepper noise. Most of the existing image denoising algorithms consider edge as a noise. Here, the proposed algorithm can set out to resolve this ambiguity. The concept of directional filters is being used to delineate the edges from noise. The proposed algorithm performance is tested for different noise densities ranging from 5% to 90% on both the greyscale and colour images. It is compared with the current state of art techniques using several performance metrics such as peak signal-to-noise ratio (PSNR), structural similarity index measure (SSIM) values, and image enhancement factor (IEF). The results showed that the proposed algorithm has achieved an improvement of 60% over the state of art techniques.

Published: July 2022

Background:

The EXCEL trial (Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) demonstrated in patients with left main coronary artery disease, no significant difference between coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) with everolimus-eluting stents for the composite end point of death, stroke, or myocardial infarction at 5 years. However, all-cause mortality at 5 years was higher with PCI. Long-term cost-effectiveness of these 2 strategies has heretofore not been evaluated.

Methods:

From 2010 to 2014, 1905 patients with left main coronary artery disease were randomized to CABG (n=957) or PCI (n=948). Costs ($2019) were assessed over 5 years using resource-based costing and Medicare reimbursement rates. Health utilities were assessed using the EuroQOL 5-dimension questionnaire. Five-year EXCEL data in combination with US lifetables were used to develop a Markov model to evaluate lifetime cost-effectiveness. An incremental cost-effectiveness ratio <$50 000 per quality-adjusted life year (QALY) gained was considered highly cost-effective.

Results:

Index revascularization procedure costs were $4,850/patient higher with CABG, and total costs for the index hospitalization were $17 610/patient higher with CABG ($32 297 versus $19 687,
P
<0.001). Cumulative 5-year costs were $20 449/patient higher with CABG. CABG was projected to increase lifetime costs by $21 551 while increasing quality-adjusted life expectancy by 0.49 QALYs, yielding an incremental cost-effectiveness ratio of $44 235/QALY. In a post hoc sensitivity analysis using mortality hazard ratios from a meta-analysis of all randomized CABG versus PCI in left main disease trials, the gain associated with CABG was 0.08 to 0.14 QALYs, resulting in an incremental cost-effectiveness ratio of $139 775 to $232 710/QALY gained.

Conclusions:

Based on data from the EXCEL trial, CABG is an economically attractive revascularization strategy compared with PCI over a lifetime horizon for patients with significant left main coronary artery disease. However, this conclusion is sensitive to the long-term mortality rates with the 2 strategies, and CABG is no longer highly cost-effective when substituting the pooled treatment effect from the 4 major PCI versus CABG trials for left main disease.

Published: July 2022

This article concerns The Zone, an interactive sound installation by the collaborative group Volumetric Units. It focuses on the installation’s philosophical and creative aspects through a reflective analysis. The Zone expresses the phenomenological experience of hyperreal cyberspace: a condition where the shift in consciousness causes an inability to distinguish reality from the simulation of reality. The installation is an investigation of the sociopolitical effects of hidden online processes. The work intends to provoke a feeling of condensed confusion like the hyperreality that we experience online, a sense of dissolution of information that is followed by a dissolution of meaning.

Published: July 2022

Singular value decomposition (SVD) is a mathematical technique used throughout the sciences and engineering, which decomposes data, represented in terms of matrices, to construct an “optimal base” that can contain key information. SVD serves as a conceptual framework in Singular Value Decomposition, a performance by a research collective consisting of Janet Biggs (visual artist), Agnieszka Międlar (mathematician), and Daniel Tapia Takaki (physicist) with dancer Vinson Fraley and musician Earl Maneein and supported by the Integrated Arts Research Initiative (IARI) at the Spencer Museum of Art. Their work together aimed to be substantive to their fields and generative of each other. Drawing from discussions of tool-sharing in the philosophy of science and performative research paradigms, this article examines the collaboration and performance to consider the sharing of conceptual frameworks as an approach to collaborative, interdisciplinary research.
Knowledge as a Mental State in Muʿtazilite Kalām
Authors: Benevich Fedor
Published: July 2022

It is commonly accepted that the definition of knowledge is not among the main epistemological concerns of the period between Plato and Edmund Gettier. Kalām is an exception to the rule. Kalām scholars provide a detailed philosophical analysis of the difference between knowledge and mere true belief. In this article, I am focusing on the analysis of knowledge in one tradition of kalām, Bahšamite Muʿtazilism. I will argue that knowledge is a factive mental state for the Bahšamites. I will also show that the Bahšamite definition of knowledge is a combination of internalism and externalism with respect to justification.

Authors: Berenson Adam , Doran Marisa , Strollo Brian , Burton Jeff , Townsend Michael , Babin Jonathan , Millien Jeffanne , Brown Russell , Fuhrman George
Published: July 2022

Background

Percutaneous cholecystostomy tube (PCT) drainage is an effective management strategy for acute cholecystitis in patients medically unfit for surgery. However, little is known about the fate of patients managed by PCT. We conducted this study to determine tube management outcomes for patients with acute cholecystitis managed by PCT.

Methods

The electronic record was queried to identify patients with acute cholecystitis managed by PCT from 2012-2020. Patients were divided into three groups for analysis: 1) ultimately managed by cholecystectomy, 2) eventual confirmation of distal flow of bile from the gallbladder and tube removal, and 3) tubes left in place without further management.

Results

A total of 179 patients with acute cholecystitis treated by PCT were included. Sixty-six patients never fully recovered from the medical insult associated with their diagnosis of acute cholecystitis and had their tubes left in situ. Sixty-four of these 66 patients (97%) died during follow-up. The remaining 113 patients recovered from their illness and presented to clinic for evaluation for tube removal and/or cholecystectomy. When distal biliary flow was confirmed, tube removal was favored (n = 70). When cystic duct outflow occlusion persisted, cholecystectomy was planned for patients who became acceptable surgical candidates (n = 43). For patients managed by cholecystectomy, 8 were approached open and 35 laparoscopically, with 12 of 35 (34.3%) converted to open and 23 (65.7%) completed laparoscopically.

Conclusion

Our study favors PCT removal for patients who recover from their acute illness when distal bile flow from the gallbladder is confirmed. We reserve cholecystectomy for patients who recover from their illness and demonstrate persistent cystic duct outflow obstruction.

This article describes a rare case of a traumatic splenic arteriovenous fistula (AVF) causing portal hypertension in a patient presenting with abdominal pain, diarrhea, and melena. A 78-year-old was admitted to the hospital with abdominal pain. The patient’s history was notable for prior laparotomy and left nephrectomy for a gunshot wound. Workup demonstrated portal hypertension with a dilated splenic vein with aneurysmal changes and a saccular celiac artery aneurysm. Celiac angiogram demonstrated a communication between celiac and portal circulation. The patient underwent laparotomy with ligation of the splenic artery and resection of the celiac artery aneurysm. In conclusion, splenic AVFs are relatively rare in clinical practice. Once the diagnosis is established, operative intervention is required to avoid complications of portal hypertension. Surgical ligation has been used in this case with a successful outcome.

Objective

To evaluate the safety, feasibility, and preliminary effectiveness of implementing supervised exercise programming into the clinical care of individuals with advanced cancer.

Design

Single group implementation feasibility study using a pre–posttest design.

Setting

Exercise Oncology Unit of the Spanish Cancer Association (a cancer-specific community facility outside the hospital setting).

Participants

Adult individuals with advanced cancer profile involving advanced local cancer or distant metastases.

Intervention

A 12-week, twice-weekly, supervised, clinic-based multi-component exercise program.

Main Measure

Paired t-tests were used to assess pre–post changes and analyses of covariance were used to compare effects based on selected participant characteristics.

Results

Eighty-four individuals with advanced cancer completed the baseline assessment, with six participants withdrawing prior to the start of the program. Of the 78 participants, 17 dropped out, thus, a total of 61 completed the final assessment. Mean adherence was 82.5%. No serious adverse events occurred. Exercise significantly improved VO2max by 5.2 mL·kg·min ( p < 0.001), chest strength ( p < 0.001), leg strength ( p < 0.001), lean body mass ( p  =  0.003), skeletal muscle mass ( p < 0.002), % body fat ( p  =  0.02), quality of life by 5.3 points ( p  =  0.009), fatigue by 3.2 points ( p  =  0.012), and physical activity by 1680 METs/week ( p < 0.001).

Conclusions

Our clinically supervised and tailored exercise program involving moderate to vigorous intensity exercise was found to be feasible, safe, and effective for individuals with advanced cancer.

Implications for Cancer Survivors

With proper screening and supervision, individuals with advanced cancer can benefit from tailored exercise oncology support as part of an overall therapeutic care plan.
“The Impact of Pharmacists Engaged in Collaborative Practice Agreements in the United States”
Authors: Kerelos Theopeste , Gangoo-Dookhan Tricia
Published: July 2022

Purpose

To evaluate the role and impact of pharmacists in collaborative practice agreements (CPAs) in the United States.

Methods

An electronic literature review was conducted on studies addressing pharmacists’ involvement in CPAs. Articles included in the review were peer-reviewed studies conducted on adults and published between 2017 and 2022. Articles investigating children were excluded.

Results

Of the articles identified, 8 studies met the eligibility criteria and were selected for the literature review. All of the studies were published between 2017 and 2022 in English in the United States. CPAs were already in place in 7 of the studies with variances due to different healthcare settings and patient populations. The studies evaluated the effect of pharmacist engagement in CPAs on the attainment of clinical and financial goals, satisfaction with pharmacist involvement, and existing barriers to pharmacist engagement in CPAs. Findings showed that pharmacist engagement in CPAs had a positive impact on the attainment of the desired clinical and financial goals, and providers were satisfied with pharmacist involvement. A common barrier to pharmacist involvement was the lack of reimbursement.

Conclusion

Pharmacists engaged in CPAs have a positive impact on healthcare, and there are opportunities for expansion of pharmacists’ roles in CPAs, particularly in non-traditional settings.

During the Covid-19 health emergency, the self-assessment of psychological relapses in 24 health workers through a Covid-19 Emergency Triage Card sought to examine how doctors, health technicians, nurses and auxiliaries perceived their mental state immediately after the communication coronavirus positivity. A Covid-19 Emergency Triage Card consisting of two sections was submitted to the study sample. First section personal data: age, sex, educational qualification, seniority, marital status, offspring, job, workload in hours, presence of night shifts, lifestyle habits (use of alcohol, tobacco, coffee). Second section: self-assessment of the psychological repercussions of the pandemic event with five sub-dimensions: anxiety; psychosomatic disorder; depression; thought disorder. behavioral changes, rated on a three-level scale: mild - medium - severe. The analysis of our results shows that anxiety-depressive symptoms take on significant values in Covid-19 positive healthcare personnel, with greater predominance among nurses. This results in identifying workers most at risk of adverse mental health outcomes during times of health emergency is a public health task. Ensuring the physical and mental health of health care workers is crucial to maintaining a high level of health care in the population.
How and When Can Robots Be Team Members? Three Decades of Research on Human–Robot Teams
Authors: Wolf Franziska Doris , Stock-Homburg Ruth Maria
Published: July 2022

Artificial intelligence and robotic technologies have grown in sophistication and reach. Accordingly, research into mixed human–robot teams that comprise both robots and humans has expanded as well, attracting the attention of researchers from different disciplines, such as organizational behavior, human–robot interaction, cognitive science, and robotics. With this systematic literature review, the authors seek to establish deeper insights into existing research and sharpen the definitions of relevant terms. With a close consideration of 150 studies published between 1990 and 2020 that investigate mixed human–robot teams, conceptually or empirically, this article provides both a systematic evaluation of extant research and propositions for further research.
Evaluating the Impact of a Pharmacist-Led Antimicrobial Stewardship Intervention at Discharge in a Community, Nonteaching Hospital

Introduction:

Approximately 30% to 50% of hospital discharge antimicrobials are inappropriate. Limited data exist on approaches to improve antimicrobial prescribing practices at the time of discharge from a community hospital. Objective: To assess the impact of a comprehensive pharmacist-led antimicrobial stewardship intervention at discharge.

Methods:

We conducted a quasi-experimental, pre-post study. A biphasic intervention took place on 2 medicine units from November 2019 to May 2020 at a community hospital. Baseline data were collected, followed by prescriber education on antimicrobial stewardship to both units (education phase). Next, a pharmacist-led intervention took place on one unit (intervention phase). The primary outcome was composite appropriateness of an oral antimicrobial prescribed to an adult at the time of discharge, defined by narrow spectrum of activity, dosing, and duration of therapy. The primary outcome was assessed using Fisher exact test.

Results:

Baseline composite appropriateness was 30% (n = 12) on the control unit and 30.8% (n = 20) on the intervention unit. From baseline to posteducation, no significant change in composite appropriateness was found on the control (30% to 26.7%, P = 0.256) or intervention (30.8% to 19.4%, P = 0.09) unit. There was no significant difference between the education to intervention phase (26.7% vs 35%, P = 0.254) on the control unit. On the intervention unit, a significant difference in composite appropriateness was found from the education to intervention phase (19.4% vs 47.8%, P = 0.017).

Conclusion and Relevance:

A pharmacist-led intervention improved appropriateness of oral antimicrobials prescribed at discharge. One-time education was insufficient for improving antimicrobial stewardship.
