Authors: Kadhim Dhahir J. , Almomin Ammar MS , Mansour Abbas A. 
Published: June 2023

AbstractIntroduction Testosterone levels and erectile function are known to decline as men age, leading to hypogonadism and erectile failure. Men with type 2 diabetes mellitus (T2DM) have a high prevalence of hypogonadism and erectile dysfunction. We aimed to estimate the prevalence of hypogonadism in T2DM patients complaining of erectile dysfunction.Patients and Methods A cross-sectional study was conducted at Specialized Diabetes, Endocrine, and Metabolism Center from early September 2021 to the end of January 2022. The study included 115 fully anonymized randomly selected patients. Patients with diabetes were assessed for erectile dysfunction through a questionnaire derived from “The International Index of Erectile Function (IIEF).” Additionally, hypogonadism has been diagnosed with serum testosterone levels lower than 264 mg/dL according to the Endocrine Society 2018 criteria for the diagnosis of male hypogonadism.Results The average duration of diabetes was 6.2 years, and the mean glycated hemoglobin value was 9.3%. Dyslipidemia was the most prevalent chronic comorbid condition (84.3%) accompanying diabetes and erectile dysfunction, followed by hypertension (56.5%). An approximately similar rate of hypogonadism was observed in patients with diabetes and erectile dysfunction regardless of whether the other chronic disease was also present. From 115 patients included in this study, hypogonadism was diagnosed in 26% of patients with diabetes and erectile dysfunction.Conclusion A significant number of hypogonadisms occur in patients with diabetes and erectile dysfunction, which require particular emphasis.

AbstractThe National Institute for Occupational Safety and Health (NIOSH) evaluated continuous and impact noise exposures and hearing loss among workers at a hammer forge company. Full-shift personal noise exposure measurements were collected on forge workers across 15 different job titles; impact noise characteristics and one-third octave band noise levels were assessed at the forge hammers; and 4,750 historic audiometric test records for 483 workers were evaluated for hearing loss trends. Nearly all workers' noise exposures exceeded regulatory and/or recommended exposure limits. Workers working in jobs at or near the hammers had full-shift time-weighted average noise exposures above 100 decibels, A-weighted. Impact noise at the hammers reached up to 148 decibels. Analysis of audiometric test records showed that 82% of workers had experienced a significant threshold shift, as defined by NIOSH, and 63% had experienced a standard threshold shift, as defined by the Occupational Safety and Health Administration (OSHA). All workers with an OSHA standard threshold shift had a preceding NIOSH significant threshold shift which occurred, on average, about 7 years prior. This evaluation highlights forge workers' exposures to high levels of noise, including impact noise, and how their hearing worsened with age and length of employment.

Abstract
Background Caregivers form an integral part of the psychosocial management of patients with psychiatric conditions. Caregivers of patients with major psychiatric disorders feel burdened, as these disorders are unpredictable and long lasting. The study was aimed to assess the quality of life (QOL) and expressed emotion among caregivers of patient's with psychiatric disorders.
Materials and Methods A cross-sectional descriptive design was adopted for the study. The sample consisted of 300 caregivers of psychiatric patients who visited psychiatric outpatient department and inpatient department of selected hospital. The caregivers were selected by using convenient sampling technique. Baseline proforma, the World Health Organization Quality of Life Scale (WHO QOL BREF), and Family Attitude Scale were used to collect the data.
Results Descriptive and inferential statistics were used to analyze the data. The analysis revealed that there was a weak negative correlation between QOL and expressed emotions. The obtained “r” value (−0.14) was statistically not significant at 0.05 level of significance. Hence, the research hypothesis was rejected and the null hypothesis was accepted.
Conclusion The study concluded that there was a low negative correlation between QOL and expressed emotions. The obtained “r” value (−0.14) is statistically not significant at 0.05 level of significance. But there was association between QOL and income and occupation of the caregiver.

Published: June 2023

AbstractIntracerebral hemorrhage (ICH) is a rare and fatal complication of immune thrombocytopenia. ICH is more common in children than in the adult population. A 30-year-old male patient, a known case of immune thrombocytopenia, presented with sudden onset severe headache and vomiting. Computed tomography scan showed a large right frontal intracerebral hematoma. His platelet counts were low, and he received multiple transfusions. Though he was initially conscious, his neurological condition progressively deteriorated, so the decision was taken for an emergency craniotomy. Despite multiple transfusions, his platelet counts were 10,000/µL, so craniotomy was very risky. He underwent an emergency splenectomy and received one unit of single donor platelets. Subsequently, his platelets count increased a few hours after, and he underwent successful evacuation of intracerebral hematoma. He eventually had an excellent neurological outcome. Though intracranial hemorrhage carries significant morbidity and mortality, a timely decision of emergency splenectomy followed by craniotomy can result in an excellent clinical outcome.

Published: June 2023

AbstractAstroblastoma is a rare tumor, which is mostly found in pediatric population. Due to scarcity of literature, the data about treatment is lacking. We are reporting case of brainstem astroblastoma in an adult female. A 45-year-old lady presented with complaint of headache, vertigo, vomiting, and nasal regurgitation for 3 months. On examination, she had weak gag, left hemiparesis. Magnetic resonance imaging brain reported medulla oblongata mass, dorsally exophytic. She underwent suboccipital craniotomy and decompression of mass. Histopathology confirmed diagnosis of astroblastoma. She underwent radiotherapy and recovered well. Brainstem astroblastoma is an extremely rare entity. The surgical resection is possible due to well-defined plane. For best outcome, maximum resection and radiation are indicated.

Published: June 2023

AbstractThe de novo development of cerebral arteriovenous malformations (AVMs) in adults is an exceedingly rare event that has prompted the theory that a “second hit” is required to induce AVM formation. The authors document development of an occipital AVM in an adult a decade and a half after a brain magnetic resonance imaging (MRI) disclosed no abnormality. A 31-year-old male with a family history of AVMs and a 14-year history of migraines with visual auras and seizures presented to our service. Because of the onset of a first seizure and migraine headaches at age 17, the patient underwent high-resolution MRI that showed no intracranial lesion. After 14 years of progressively worsening symptoms, he underwent a repeat MRI that demonstrated a new de novo Spetzler-Martin grade 3 left occipital AVM. The patient received anticonvulsants and underwent Gamma Knife radiosurgery for his AVM. This case suggests that patients with seizures or persistent migraine headaches should have periodic repeat neuroimaging to exclude the development of a vascular cause despite an initial negative MRI.
Epidemiology and Predisposing Factors of Post-COVID Venous Thrombosis: A Concise Review
Authors: Lippi Giuseppe , Favaloro Emmanuel J. 
Published: June 2023

AbstractLong-coronavirus disease 2019 (COVID-19) represents a heterogeneous clinical syndrome characterized by a pathologic continuum of signs, symptoms, and also laboratory/radiologic abnormalities that may persist for a long time after recovering from an acute severe acute respiratory syndrome-coronavirus disease 2 infection. Among the various components of this postviral condition, the risk of venous thromboembolism in patients hospitalized for COVID-19 remains considerably higher after discharge, especially in older individuals, in men, in patients with longer hospital stays and more aggressive treatment (e.g., mechanical ventilation and/or intensive care), when thromboprophylaxis is not used, and in those with a persistent prothrombotic state. Patients who have these predisposing factors should be monitored more closely to intercept any thrombosis that may occur in a post-COVID time-related manner but may also benefit from extended thromboprophylaxis and/or antiplatelet therapy.
Percutaneous Intentional Extraluminal Recanalization of Chronic Total Occlusions: A Review of Reentry Devices
Authors: Kinariwala Dhara , Taylor Amy C. , Wilkins Luke R. 
Published: June 2023

AbstractPercutaneous intentional extraluminal recanalization (PIER) is an endovascular subintimal crossing technique used to treat chronic total occlusions (CTOs) of the peripheral arteries. Intraluminal revascularization remains the standard over PIER when technically feasible; however, when intraluminal approaches fail, PIER may be preferred prior to pursuit of surgical bypass grafting. The major cause of failure of PIER is inability to reenter the true lumen after crossing the CTO. Therefore, several reentry devices and endovascular techniques have been developed to allow for the operators to safely and quickly access the true lumen distal to the occlusion. Reentry devices currently available on the market include the Pioneer Plus catheter, Outback Elite catheter, OffRoad catheter, Enteer catheter, and GoBack catheter. These devices have unique methods of use and specific advantages with regard to their technical success along with reduced procedural and fluoroscopic time. In addition, there are other endovascular techniques available that may facilitate true lumen reentry and these will also be reviewed.
Surgical, Endovascular, and Multimodal Approaches to the Management of Atherosclerotic Common Femoral Artery Disease
Authors: Kugler Nathan W. 
Published: June 2023

AbstractCommon femoral artery disease is at the heart of nearly all treatment algorithms and decisions for patients with symptomatic peripheral arterial disease. Surgical endarterectomy has been the mainstay of common femoral treatment with a wealth of data supporting its safety, efficacy, and durability. Advances in endovascular technology and techniques for the management of iliac and superficial femoral artery disease has resulted in a paradigm shift in management. The common femoral artery has been aptly named a “no stent zone” due to anatomic and disease-specific challenges that have limited the role for endovascular techniques. New technology and techniques in the endovascular management of common femoral disease seek to change our treatment strategies. A multimodal approach utilizing a combination of angioplasty, atherectomy, and stenting has been shown most beneficial, although limited long-term data leave durability an unanswered question. While surgical treatment remains the gold standard, advances in the endovascular approach will certainly continue to improve outcomes. As truly isolated common femoral disease is a rarity, a collaborative approach combining all benefits of open and endovascular techniques in the treatment of peripheral arterial disease is essential.

Published: June 2023

Ultra-fast high-voltage switches (UFHVSs) are a core component of time-of-flight mass spectrometers for realizing high accuracy ion acceleration, deceleration, and temporal focusing. The desirable features of high performance UFHVSs include a large range of adjustability of pulse width, a high maximum output amplitude, and minute rising and falling times. Besides the simplicity of the driver circuit, the total cost of the whole device is also critical to its practical applications. In this work, we present a low-cost and easy-fabrication 5000 V bipolar solid-state UFHVS for a high-resolution mass spectrometer. A double-pulse transformer isolates the circuit’s high- and low-voltage sides and synchronously drives series-connected cascode SiC FETs to form its push–pull topology. This scheme allows transmitting drive signals with long widths but without the magnetic saturation of the transformer. Testing results show that output pulses reach a maximum voltage of 5000 V and a width of 150 µs, with rising and falling times of 8.5 and 18.3 ns, respectively. More importantly, they have nearly no voltage decay.

Published: June 2023

Argon dielectric barrier discharge driven by the dual frequency at atmospheric pressure has been investigated by a 1D fluid model. Temporal evolutions of voltage and charge density on dielectric surface, fluxes of electrons and ions on the surface, the spatiotemporal distribution of electron generation rate, and the spatial distribution of electron density are studied with various low-frequency (LF) voltages. Minimum sustained discharge amplitude of high frequency (HF) voltage and spatiotemporal mean electron density over one LF period varying with sheath voltage (α → γ) are also discussed. Results show that in α mode, the electron flux on the dielectric surface decreases significantly when the LF voltage amplitude is lower while the ion flux is less affected. The positive charge density on the surface increases, causing the surface voltage waveform to shift upward. When the LF voltage amplitude is 40 V and that of HF voltage is 87 V, the positive and negative values of voltage amplitude of dielectric surface are 182 and 32 V. As the LF voltage amplitude increases further, the sheath formation time is significantly delayed and the discharge terminates, and the rate of electron generation decreases significantly. The discharge is extinguished when the amplitude of LF voltage is 68 V while it regains when the amplitude reaches up to 750 V. In γ mode, when the amplitude of HF voltage reaches or exceeds its minimum sustained discharge value, the generation and distribution of electrons are almost unaffected by the amplitude of LF voltage.

Published: June 2023

Abstract
Magnetic textures in the self-supported nanostructure, such as vortex, are promising for magnetic hyperthermia therapy and spintronics due to their low remanent state and topological protection. These configurations emerge from energy minimization in confined systems, such as nanodisk or nanoparticles. There are many techniques used to confine these magnetic textures. However, the most robust, cheap, and reproducible is always sought. This work applies colloidal lithography to produce self-supported nanocaps with a vortex as the ground state. Firstly, we perform micromagnetic simulations to determine which diameters and thicknesses stabilize the vortex as a ground state on nanocaps. Secondly, we simulate the magnetization curves to find the conditions with the smallest remanent state and largest loop hysteresis curves area. Finally, we experimentally corroborate the vortex configuration ground state using electron holography and vibrating the sample magnetometer. In addition, we performed a dynamic simulation to investigate the gyrotropic modes of the vortex core. We present a concise route to the fabrication of scalable vortex magnetic nanocaps. Our results show that the magnetic nanocaps produced have a great potential for application in medicine, such as magnetic hyperthermia, and in spintronics, for spin-transfer torque nano-oscillators.

Published: June 2023

Abstract
Binocular vision can get the three-dimensional information of the objects according to two-dimensional images. However, when the background texture information of the workpiece to be measured is weak, or the depth information cannot be recognized due to the change of viewing angle, it will lead to poor three-dimensional measurement accuracy. To address this problem, the paper proposes a multi-view workpiece 3D measurement method based on binocular vision. First, an experimental bench with a Chessboard is designed. The corner point reconstruction is realized by extracting the corner point of the calibration plate. The checkerboard plane is fitted by the least squares method to obtain the checkerboard plane mathematical model. Then, the vertices of the workpiece are extracted at the subpixel level, and a minimum distance sparse vertex stereo matching algorithm (EDMS) based on Euclidean distance metric is proposed to achieve accurate and fast corner matching. Finally, the three-dimensional dimensions of the workpiece are calculated. Through experiments on multiple angles of the two workpieces, the results show that the average absolute error measured by the method at different angles is 0.33 mm, the total relative error is 0.90%, and the variance is less than that 0.01 mm2, realizing the more accurate measurement of multi-view three-dimensional dimensions of small workpieces. This paper provides a new binocular vision handheld mobile 3D measurement equipment method.

Published: June 2023

Abstract
Nowadays, the methods of remaining useful life (RUL) prediction based on deep learning only use single model, or a simple superposition of two models, which makes it difficult for to maintain good generalization performance in various prediction scenarios, and ignores the dynamic sensitivity of features in the prediction, limiting the accuracy. This paper proposes a method of RUL prediction of bearing using fusion network through two-feature cross weighting (FNT-F). First, a fusion network with two subnets is proposed in this paper to adapt to the prediction problem in different scenarios. Meanwhile, a method of cross weighted joint analysis of the two features is proposed to make up for the shortcomings of feature analysis and achieve complementarity between time-domain and time–frequency features.

m s−2 is obtained by using a simple pendulum. It shows that the accuracy levels of the two techniques are comparable. Therefore, Lato Lato can be used as a simple and low-cost experimental tool for measuring the acceleration due to gravity. It is supposed to become an addition to methods that are commonly used, such as a simple pendulum and a physical pendulum.

Abstract
Research on piezoelectric microgenerators harvesting energy from vibrations led to an abundant literature, with various strategies to optimize the frequency range and output power. In contrast, for very low frequency range (<10 Hz) and/or for non-harmonic mechanical source, the large majority of the strategies are not adapted. This work deals with a small scale piezoelectric generator where the input mechanical source consists of a single force application in the range of hundreds of Newtons (i.e. typical human weight). Contrary to harmonic mechanical sources, such an application context necessitates harvesting as much as energy as possible in a single cycle. This was achieved by assembling several piezoelectric stacks within a mechanical amplification system, and to use the electric field and stress levels close to the limits of the piezoelectric elements. Ericsson cycle (i.e. thermodynamic cycle comprising two iso-electric field and two iso-stress steps) was applied to the piezoelectric material and later two device prototypes were developed in order to quantify the harvesting capabilities. Finally, in a realistic application point of view, a passive electrical interface based on Bennet’s doubler was implemented and compared to the Ericsson cycles in terms of output energy. This electrical energy management strategy successfully allowed working at ultra-high electric field (>2 kV mm−1) enabling a converted energy density close to the ultimate value. An maximal energy density of 320 mJ cm−3 was reached using Ericsson cycles, and 130 mJ cm−3 using Bennet’s doubler (∼40% of the ultimate energy density). The device comprising ∼2.4 cm3 of piezoelectric material, the net output energy converted and stored per cycle reached 320 mJ. Still, the work presented here can be adapted to other range of forces and displacements for maximizing energy harvesting.
