Published: August 2022

AbstractMeasurement data based on current and voltage of photovoltaic (PV) systems and the establishment of more accurate and stable solar system models are of typical significance for the design, control, evaluation and optimization of PV systems. Accurate and stable parameter evaluation for PV systems needs to be based on more efficient optimization techniques to achieve efficient energy conversion from solar energy. Therefore, this paper proposes a novel and efficient optimization technique enhanced colony predation algorithm to solve the complex PV parameter identification problem named ECPA. By fusing extremal optimization strategy and Nelder–Mead simplex method enables ECPA to further develop in the neighborhood of potential optimal solutions while improving the position of inferior agent candidates, and finally has the ability to search globally beyond the local optimum. To verify the optimization efficiency of ECPA, the first part verifies the efficiency of ECPA in solving complex high‐dimensional and multimodal problems by conducting competitive comparison experiments at the IEEE CEC 2020 benchmark case. In the second part, ECPA is compared with nine similar published state‐of‐the‐art algorithms, and competitive tests for PV parameter identification under single diode model, double diode model, triple diode model and PV module model (PV) are conducted. Finally, we focused on three different commercial PV models (thin film ST40, monocrystalline SM55, and multicrystalline KC200GT) to test the accuracy of ECPA in evaluating PV parameters. The test results show that ECPA is able to maintain a high level of accuracy and stability when dealing with commercial PV models in complex environments. The experimental results demonstrate that ECPA outperforms other algorithms in terms of data fitting, stability, convergence speed and convergence accuracy. All the competitive experimental results show that ECPA can be a novel technique with the best performance for identifying the parameters to be determined in solar PV systems.

Authors: Löjdahl Erika , Lindam Anna , Asklund Ina 
Published: August 2022

AbstractBackground and AimsPelvic floor muscle training (PFMT) is recommended for continent pregnant women and postnatal women experiencing urinary incontinence (UI). The app Tät® has been developed for the treatment of stress UI with a focus on PFMT. The aim of this study was to investigate factors associated with the improvement of incontinence symptoms and retained continence in pregnant and postnatal women who used the app.MethodsA prospective cohort study was carried out based on user questionnaires from the app Tät®. We included pregnant and postnatal women who answered the inclusion questionnaire between June 19, 2019 and September 19, 2020. The questionnaire included questions about the frequency and amount of leakage, the impact that UI has on everyday life, and experienced improvements at follow‐up. We analyzed factors associated with improvement and retained continence using logistic regression.ResultsWe included 10,307 pregnant and 13,670 postnatal women, and 44% of the pregnant women and 52% of the postnatal women were incontinent. A total of 3680 women were included in the follow‐up analysis, and 52% of the pregnant incontinent women and 73% of the postnatal incontinent women experienced improvement. Pregnant women who performed PFMT and used the app at least once per week had increased odds of improvement (odds ratio [OR]: 1.83, 95% confidence interval [CI]: 1.01–3.29 and OR: 3.38, 95% CI: 1.94–5.90, respectively) compared to those who performed no training and had no app usage. Postnatal women who used the app at least once per week and had more severe incontinence had increased odds of improvement (OR: 4.26, 95% CI: 2.37–7.64 and OR: 1.11, 95% CI: 1.05–1.16, respectively).ConclusionsThe app Tät® is widely used by pregnant and postnatal women in Sweden for the prevention and treatment of UI. Majority of the women with incontinence experienced improvement after using the app. Regular PFMT and app use seemed to be important factors for experiencing improvement.

Published: August 2022

AbstractCOVID‐19 is not only limited to a defined array but also has expanded with several secondary infections. Two uncommon opportunistic fungal infections, COVID‐19 associated mucormycosis (CAM) and aspergillosis (CAA), have recently been highly acquainted by many worldwide cases. Two immune response deteriorating factors are considered to be responsible for immunosuppression: comorbidities and medication. Due to unlike infection sites and patterns, CAM and CAA‐associated factors deflect a few degrees of proximity, and the present study is for its assessment. The study evaluated 351 CAM cases and 191 CAA cases retrieved from 65 and 53 articles based on inclusion criteria, respectively. Most of the CAM reported from India and CAA were from four South‐European and West‐European neighbor countries. The mean ages of CAM and CAA were 52.72 ± 13.74 and 64.81 ± 11.14, correspondingly. Mortality of CAA (56.28%) was two times greater than CAM (26.02%). Nevertheless, the count of diabetes cases was very high in CAM compared to CAA. The main comorbidities of CAM were diabetes (nearly 80%) and hypertension (more than 38%). All noticeable complications were higher in CAA except diabetes, and these were diabetes (34.55%), hypertension (45.03%), and obesity (18.32%). Moreover, pre‐existing respiratory complications like asthma and chronic obstructive pulmonary disease are visible in CAA. The uses of steroids in CAM and CAA were nearly 70% and 66%, respectively. Almost one‐fourth of CAA cases were reported using immunosuppressant monoclonal antibodies, whereas only 7.69% were for CAM. The overall finding highlights diabetes, hypertension, and steroids as the risk factors for CAM, whereas obesity, chronic pulmonary disease, and immunosuppressants for CAA.

Published: August 2022

AbstractThis paper presents turbulent heat transfer performance and entropy production rate in different inwardly corrugated pipes with single‐walled carbon nanotube (SWCNT)/H2O nanofluid as a working fluid using the finite volume method approach. The configurations considered were circular, triangular, and trapezoidal. The SWCNT/H2O nanofluid was modeled using a single‐phase approach and the model was used to simulate the turbulent flow. A parametric study was carried out on the effect of Reynolds number (5 × 103 ≤ Re ≤ 3 × 104) and nanoparticle volume ratio (0% ≤ φ ≤ 0.25%) on hydrodynamic, heat transfer performance, thermal entropy production rates (TEPRs; due to mean and turbulent temperature gradients), and viscous entropy production rates (VEPRs; due to mean and turbulent velocity gradients). The results showed that the mean temperature gradient contributes most to the TEPR, compared with the turbulent temperature gradient. However, the opposite was the case for the VEPR. Furthermore, the presence of corrugation decreases the TEPR but enhanced friction factor, Nusselt number, and VEPR. For example, at a Reynolds number of 2.5 × 104, the normalized friction factor, average Nusselt number, TEPR, and VEPR (referencing a smooth pipe) in circularly, triangularly, and trapezoidal corrugated pipes are {3.86, 1.39, 0.80, 3.88}, {3.80, 1.41, 0.72, 3.98}, and {4.34, 1.55, 0.69, 4.19}, respectively.

Published: August 2022

AbstractThe notion of this paper is to analyse the bidimensional, steady flow of a dusty fluid over a heated plate with varied fluid properties and magnetic fields. The boundary layer flow directed by Lapwood–Forcheimer–Brinkman extended Darcy model and Lorentz force are highly coupled and nonlinear. Similarity terms convert these nonlinear partial differential equations to higher‐order ordinary differential equations. These higher order ordinary differential equations (ODEs) are converted to first order ODE by the numerical technique called the shooting technique. Temperature, concentration, and velocity are portrayed for various pertinent parameters, and it is spotted that due to the particles in the fluid, the heat transfer speeds up and temperature and concentration decrease. Nusselt number, Skin fiction, and Sherwood number also have been discussed here. The results are in keeping with the existing results. In understanding the thermal characteristic of various effects, it was seen that thermogeometric plate, radiation conduction is very useful for many industrial applications.
Management information system maturity concerns in Nigeria public organizations
Authors: Adetunji Rose Oluwaseun , Singh Shawren , Mkhize Peter 
Published: August 2022

AbstractGovernment departments are under increasing pressure to demonstrate technology effectiveness. One approach that government departments can use to be perceived as more technology effective is to understand the Management Information Systems (MIS) maturity issues that affect their departments. There are gaps in the academic literature about how African governments are dealing with the issues of MIS maturity; and this is also applicable to Nigeria. The purpose of this research is to gain a better understanding of some of the MIS maturity concerns of Nigerian Ministries, Department, and Agencies (MDAs). This is important because senior managers and policymakers can more effectively understand the challenges that affect their respective departments and develop context‐appropriate policies. This study is quantitative in nature and primary data in the form of questionnaires were collected from 109 key stakeholders from selected Nigerian government departments. The data were analyzed using Factor analysis as a primary tool. The analysis provided a deeper understanding of some of the issues affecting the maturity within the selected Nigerian MDAs. The results of the analysis were used to develop a model that outlines some of the maturity concerns for the selected Nigerian MDAs. The issues that affect MIS maturity in Nigerian MDAs are related to: (1) integration of MIS initiatives, creating MIS vision, implementation of MIS management policies and the development of supportive MIS objectives which influence MIS maturity, (2) robust MIS objectives and robust MIS management that influences service delivery.

AbstractPurposeClinically significant pocket hematoma (CSH) is a common complication to cardiac implantable electronic device (CIED) surgery. We aimed to evaluate predictors of CSH after CIED surgery.MethodsWe performed a nationwide population‐based prospective cohort study with systematic patient chart review of all Danish patients undergoing CIED surgery during a 12‐month period. Multiple logistic regression analysis was used to estimate adjusted odds ratios (aOR) with 95% confidence intervals for association between predictors and CSH.ResultsWe included 5918 consecutive patients, 63% males, mean age 72.6 years. A total of 148 (2.5%) patients experienced CSH, including 10 patients (0.2%) requiring re‐operation with hematoma evacuation. The risk of CSH was significantly increased in patients treated with aspirin (aOR 1.8; 1.2–2.7), aspirin and clopidogrel (aOR 3.9; 2.3–6.5), or heparin (aOR 2.1; 1.1–4.1), and in patients with INR≥2.0 (aOR 2.0; 1.2–3.2). Patients operated by low‐volume operators (aOR 2.7; 1.6–4.6) or undergoing more complex CIED surgery such as cardiac resynchronization therapy (aOR 2.0; 1.1–3.5) or dual‐chamber defibrillator (aOR 2.1; 1.2–3.8) also had significantly increased CSH risk.ConclusionIn a large nationwide cohort of consecutive patients undergoing CIED surgery, the risk of CSH was 2.5%, with 0.2% necessitating evacuation. CSH risk was increased both in patients receiving aspirin, dual antiplatelet therapy or continued vitamin K‐antagonist therapy. Dual antiplatelet therapy had the highest risk (aOR) of CSH. Both low operator volume and more complex CIED surgery were independently associated with higher CSH risk. These data should be considered when planning CIED surgery.

AbstractBackgroundIn Saudi Arabia, three approved vaccines against severe acute respiratory syndrome coronavirus 2 (AstraZeneca [AZD1222], Pfizer‐BioNTech [BNT162b2] and [Ad26. COV 2‐S] Moderna vaccine) have been administered to the population.ObjectiveTo characterise cutaneous adverse events associated with COVID‐19 vaccines.MethodologyWe collected information on 26 patients presented to two secondary health care facilities, over the period extending from mid of December 2020 to the 1st of January 2022 with cutaneous reactions after COVID‐19 vaccine administration. Data were descriptively analysed using Statistical Package for the Social Sciences, SPSS 23rd version.ResultsA total of 53.8% of the patients were male; 31% of the patients reported having at least one chronic illness. Reactions were most frequent after the first dose (57.6% of the patients). Messenger RNA‐based vaccines were the most frequently noted vaccines associated with the reactions (76.9% of the cases). The most common reactions were cutaneous small‐vessel vasculitis (19.2%), interface/lichenoid reactions (19.2%), psoriasis (15.4%), and acute urticaria (11.5%). Only 11.5% patients required admission to the hospital for their clinical presentation.ConclusionMost of our patients had mild reactions and were successfully managed with supportive treatments. However, still some patients may experience severe or long‐lasting reactions requiring systemic therapies.

Published: August 2022

ObjectiveThe survival rate of patients with trisomy 13 and trisomy 18 has increased dramatically over the past two decades. We sought to comprehensively describe the otolaryngologic clinical characteristics and procedures required for these patients at our institution.MethodsWe performed algorithmic identification of patients with a diagnosis of trisomy 13 and trisomy 18 for whom the otolaryngology service provided inpatient or outpatient care at our institution between the dates of February 1997 and March 2021.ResultsOf the 47 patients studied, 18 patients had a diagnosis of trisomy 13, and 29 had a diagnosis of trisomy 18. Complete trisomy was present in 44% (8/18) of trisomy 13 patients and 55% (16/29) of trisomy 18 patients. 81% of patients were living at the time of the study. About 94% (44/47) of patients required consultation with another specialty in addition to Otolaryngology. Overall, the most common diagnoses among this cohort were gastroesophageal reflux disease (47%), dysphagia (40%), otitis media (38%), and obstructive sleep apnea (34%). Nearly three‐quarters (74%) of patients studied required an otolaryngologic procedure. The most common surgical procedure was tonsillectomy and/or adenoidectomy. Patients with trisomy 18 were significantly more likely to have external auditory canal stenosis and obstructive sleep apnea whereas patients with trisomy 13 were more likely to have cleft lip and palate.ConclusionsPatients with a diagnosis of trisomy 13 or 18 often require multidisciplinary management and the range of required care spans the breadth of otolaryngology.Level of Evidence4 Laryngoscope, 133:1501–1506, 2023

AbstractObjective(s)To analyze changes in tracheotomy practices at the onset of the COVID‐19 pandemic, and determine if quality patient care was maintained.MethodsThis was a single institution retrospective study that included patients undergoing tracheotomy from May 2019 to January 2021. Patients were divided into two groups, pre‐COVID and post‐COVID. Only three patients tested positive for COVID‐19, and they were excluded from the study. Data were collected from the electronic medical record. Statistical analyses were performed using 2‐tailed independent t tests, Wilcoxon Rank Sum tests, Chi‐Square tests, and Kaplan–Meier curves.ResultsThere were 118 patients in the pre‐COVID group and 91 patients in the post‐COVID group. The main indication for tracheotomy in both groups was prolonged intubation. There were no significant differences in overall length of stay, time to tracheotomy, duration of tracheotomy procedure, or time to initial tracheotomy change between the two groups. Due to protocols implemented at our institution to limit viral transmission, there were significant increases in the percent of tracheotomies performed in the OR (p = .02), and those performed via open technique (p = .04). Additionally, the median time to decannulation significantly decreased in the post‐COVID group (p = .02).ConclusionSeveral variables regarding the timing of patient care showed no significant differences between groups which demonstrates that quality patient care was maintained. It is important to note that this data was collected early in the Pandemic, and additional trends may become apparent over time.Level of evidence4.

Published: August 2022

AbstractObjectiveLowering hospital readmission rates is a national goal, and presents an opportunity to lower health care costs, improve quality, and increase patient satisfaction. We aim to assess whether discharge disposition is associated with readmission.MethodsA retrospective cohort study using logistic regression to quantify risk factors of hospital readmission in patients with confirmed head and neck cancer (HNC) who underwent surgery from 2010 to 2018 contained in the Pennsylvania Health Care Cost Containment Council database, which includes patients treated in Pennsylvania hospitals.ResultsThe readmission rate in this study was 18.1%. Cancers of the hypopharynx had the highest rates of readmission (29.2%). Male sex (odds ratio [OR]: 0.87, 95% CI: 0.75–1.00), emergent admission (vs. elective admission: OR = 1.33, 95% CI: 1.02–1.74), discharge to home health (vs. home: OR = 1.85, 95% CI: 1.59–2.16), discharge to skilled nursing facility (SNF) (vs. home: OR = 2.21, 95% CI: 1.80–2.72), and having 4+ comorbidities (vs. 0–1: OR = 1.39, 95% CI: 1.09–1.76) were significant risk factors for hospital readmission.ConclusionIt is necessary to consider the readmission risk associated with HNC patients. Reasons for readmission are multifactorial and can be related to demographics, hospital course, comorbidities, or discharge disposition–this requires further assessment. There is importance in increasing HNC awareness and staff education about the unique needs of this population.Level of Evidence4.

Published: August 2022

AbstractHybrid peptides with heterogeneous backbone are a class of peptide mimics with adjustable proteolytic stability obtained from incorporating unnatural amino acid residues into peptide backbone. α/β‐peptides and peptide/peptoid hybrids are two types of hybrid peptides that are widely studied for diverse applications, and several synthetic methods have been developed. In this mini review, the advance in hybrid peptide synthesis is summarized, including solution‐phase method, solid‐phase method, and novel polymerization method. Conventional solution‐phase method and solid‐phase method generally result in oligomers with defined sequences, while polymerization methods have advantages in preparing peptide hybrid polymers with high molecular weight with simple operation and low cost. In addition, the future development of polymerization method to realize the control of the peptide hybrid polymer sequence is discussed.

Published: August 2022

AbstractMultiparametric magnetic resonance imaging (mpMRI) is an indispensable tool in the clinical workflow for the diagnosis and treatment planning of various diseases. Machine learning–based artificial intelligence (AI) methods, especially those adopting the deep learning technique, have been extensively employed to perform mpMRI image classification, segmentation, registration, detection, reconstruction, and super‐resolution. The current availabilities of increasing computational power and fast‐improving AI algorithms have empowered numerous computer‐based systems for applying mpMRI to disease diagnosis, imaging‐guided radiotherapy, patient risk and overall survival time prediction, and the development of advanced quantitative imaging technology for magnetic resonance fingerprinting. However, the wide application of these developed systems in the clinic is still limited by a number of factors, including robustness, reliability, and interpretability. This survey aims to provide an overview for new researchers in the field as well as radiologists with the hope that they can understand the general concepts, main application scenarios, and remaining challenges of AI in mpMRI.
