Abstract Internet of Things (IoT) empowers imaginative applications and permits new services when mobile nodes are included. For IoT-enabled low-power and lossy networks (LLN), the Routing Protocol for Low-power and Lossy Networks (RPL) has become an established standard routing protocol. Mobility under standard RPL remains a difficult issue as it causes continuous path disturbance, energy loss, and increases the end-to-end delay in the network. In this unique circumstance, a Balanced-load and Energy-efficient RPL (BE-RPL) is proposed. It is a routing technique that is both energy-efficient and mobility-aware. It responds quicker to link breakage through received signal More >

Abstract Introduction: This analysis reported outcomes of treating catheter-dependent urinary retention with Rezum water vapor therapy.
Materials and methods: A prospective registry was established at two high-volume Canadian centers. Patients had baseline medical and benign prostatic hyperplasia (BPH) history documented. The subgroup of patients with refractory, catheter-dependent urinary retention was analyzed. The primary outcome was the proportion of patients who were spontaneously voiding and catheter-free at 6 months.
Results: Sixteen patients (age: 68.7 years) with catheter-dependent urinary retention were treated with Rezum. Average prostate volume was 84.4 mL and 75% had median lobe. All patients had at least one… More >

Abstract Introduction: Holmium laser enucleation of the prostate (HoLEP) is an effective but underutilized option for the surgical management of benign prostatic hyperplasia (BPH). With low adoption, questions arise surrounding patients access to care. It is unclear whether patients undergoing HoLEP are local or specifically seek care from afar. We looked to determine the proportion of patients who traveled out-of-state for HoLEP treatment and the impact of travel on peri and postoperative metrics.
Materials and methods: We performed a retrospective cohort study evaluating patients that underwent HoLEP at a single institution from 2007-2019. Patient demographic, perioperative data, postoperative… More >

Abstract Introduction: The safety and efficacy of low dose methoxyflurane disposable inhaler (Penthrox) was assessed in this study of men undergoing Rezum water vapor thermal therapy (WVTT).
Material and methods: An open-labeled, single-center study was conducted to demonstrate the safety and efficacy of using methoxyflurane inhaler during a Rezum procedure. Patients assessed current pain intensity using a 10-point Visual Analog Scale (VAS) of Pain at 4 timepoints including (1) before any medication, (2) initially after insertion of the rigid cystoscope and before any Rezum treatment, (3) immediately after final injection of Rezum treatment and (4) at discharge. Patients… More >

Abstract Background: To compare the differential diagnostic value of iterative decomposition of water and fat with the echo asymmetrical and least-squares estimation quantitation sequence (IDEAL-IQ) with that of intravoxel incoherent motion diffusion-weighted imaging (IVIM DWI) in differentiating between alpha fetoprotein (AFP)-negative hepatocellular carcinoma (HCC) and focal nodular hyperplasia (FNH). Materials and Methods: A total of 28 AFP-negative HCC cases and 15 FNH cases were scanned using the IDEAL-IQ and IVIM-DWI magnetic resonance imaging (MRI) protocols. Two radiologists independently assessed the fat fraction (FF) and the iron level surrogate (R2*) derived from the IDEAL-IQ images and the apparent diffusion… More >

Abstract In response to problems in the centralized storage of personal resumes on third-party recruitment platforms, such as inadequate privacy protection, inability of individuals to accurately authorize downloads, and inability to determine who downloaded the resume and when, this study proposes a blockchain-based framework for secure storage and sharing of resumes. Users can employ an authorized access mechanism to protect their privacy rights. The proposed framework uses smart contracts, interplanetary file system, symmetric encryption, and digital signatures to protect, verify, and share resumes. Encryption keys are split and stored in multiple depositories through secret-sharing technology to… More >

Abstract Forested areas are extremely vulnerable to disasters leading to environmental destruction. Forest Fire is one among them which requires immediate attention. There are lot of works done by authors where Wireless Sensors and IoT have been used for forest fire monitoring. So, towards monitoring the forest fire and managing the energy efficiently in IoT, Energy Efficient Routing Protocol for Low power lossy networks (E-RPL) was developed. There were challenges about the scalability of the network resulting in a large end-to-end delay and less packet delivery which led to the development of Aggregator-based Energy Efficient RPL… More >

Abstract Airline industry has witnessed a tremendous growth in the recent past. Percentage of people choosing air travel as first choice to commute is continuously increasing. Highly demanding and congested air routes are resulting in inadvertent delays, additional fuel consumption and high emission of greenhouse gases. Trajectory planning involves creation identification of cost-effective flight plans for optimal utilization of fuel and time. This situation warrants the need of an intelligent system for dynamic planning of optimized flight trajectories with least human intervention required. In this paper, an algorithm for dynamic planning of optimized flight trajectories has… More >

Abstract Introduction: To determine if focal bladder neck cautery is effective in reducing bleeding following prostate tissue resection for benign prostatic hyperplasia using Aquablation.
Materials and methods: Consecutive patients from 11 countries in Asia, Europe, and North America who underwent Aquablation for symptomatic benign prostatic hyperplasia between late 2019 and January 2021 were included in the analysis. All patients received post-Aquablation non-resective focal cautery at the bladder neck.
Results: A total of 2,089 consecutive Aquablation procedures were included. Mean prostate size was 87 cc (range 20 cc to 363 cc). Postoperative bleeding requiring transfusion occurred in 17 cases (0.8%, More >

Abstract Introduction: Five-alpha reductase (5-AR) deficiency was first identified by Imperato-McGinley and Walsh as the cause of pseudohermaphroditism in two separate studies. The discoveries led to the development of finasteride (inhibitor of type 2 isoenzyme of 5-AR) and dutasteride (inhibitor of type 1 and type 2 isoenzymes of 5-AR).
Both drugs have been proven effective for the treatment of benign prostatic hyperplasia, improving voiding symptoms, reducing the risk of urinary retention, and decreasing the need for prostate surgery.
Five-alpha reductase inhibitors (5-ARIs) have also been demonstrated to be chemopreventive agents, reducing the risk of prostate cancer, although the… More >
