Published: April 2024

Inappropriate polypharmacy is a common occurrence in elderly patients, resulting in increased adverse drug reactions, nonadherence, and increased healthcare costs. Medication review and deprescribing are the primary strategies described in the literature for dealing with problematic polypharmacy. To effectively carry out the medication review, various tools have been developed. These tools can support medication review in a variety of ways. Some tools include a list of medications requiring detailed attention, while others guide medical professionals with principles and algorithms for reviewing and prescribing medicines. A third category of tools focuses on tracking and identifying symptoms that may be due to drug-related problems.
This article aims to present the medication review support tools used in the management of polypharmacy in the geriatric population, emphasizing their advantages and disadvantages.

Published: April 2024

Introduction: The density of breast tissue, radiologically referred to as fibroglandular mammary tissue, was found to be a predisposing factor for breast cancer (BC). However, the stated degree of elevated BC risk varies widely in the literature.
Aim: The purpose of this study was to determine the relationship between different breast mammography densities and the risk of breast cancer in Egyptian women..
Patients and methods: An analytical cross-sectional prospective study was conducted at Ain Shams University Hospital and Private Centre between December 2020 and December 2021. The study included 814 asymptomatic females 40 years old or above, who came for BC screening using full-field digital mammography.
Results: The incidence of BC was found in 84 females (10.3%). Breast cancer incidence was 6.3% in females with ACR-A density, 8.5% in women with ACR-B density, 16.3% in women with ACR-C density, and 27.8% in women with ACR-D density (p&lt;0.001). Using logistic regression analysis, we showed that three types of breast density increased the risk of BC, where patients with type B, type C, and type D breast density had a 1.39, 2.92, and 3.12 times more risk for BC, respectively (p=0.010, p=0.003, and p=0.036, respectively).
Conclusion: Among Egyptian females, the incidence of BC is 10.3%. Our data revealed that the greater the breast density, the higher the incidence of BC, and affirmed that breast density is a risk factor for BC development.

Published: April 2024

Introduction: Despite significant development in systemic therapy and radiotherapy, surgery is still the cornerstone for curative lung cancer treatment. Although predicted postoperative function (ppo) somewhat exactly correlates with actual postoperative function bigger differences may be a cause of serious clinical outcome.
Aim: The aim of our study was to identify clinical factors affecting prediction accuracy of postoperative lung function for more careful selection of operable lung cancer patients.
Patients and methods: Seventy patients were studied prospectively. The preoperative lung function tests (FEV1 and DL,CO) were performed within a week before surgery, and the follow-up tests were performed 4 to 6 weeks after surgery. Calculation of predicted postoperative values were calculated by three methods: two segment formulas and vibration response imaging (VRI). The correlation between each clinical parameter and accuracy of prediction was screened on univariate analysis of Pearson’s correlation coefficient, and significant factors were confirmed by multivariate linear regression analysis applying backward stepwise elimination approach.
Results: Univariate linear regression analysis between the predicted and the actual postoperative values of FEV1% and DL,CO showed the highest prediction accuracy with acoustic mapping (VRI). Multivariate regression analysis showed that prediction accuracy of postoperative lung function is significantly affected by COPD (p&lt;0.001) and volume of resection (p&lt;0.001).
Conclusion: Vibration response imaging (VRI) is a more accurate method for predicting postoperative lung function than segment method formulas. Anatomical calculation significantly underestimates the postoperative values of FEV1% in patients with COPD. Prediction of FEV1% and DL,CO with segment counting is significantly influenced by the volume of resection.

Published: April 2024

Introduction: Tooth extraction is still one of the most common dental procedures, routinely performed for a variety of reasons. Tooth extraction forceps and elevators are well-known extraction instruments which have been the standard in tooth extraction procedures for well over a hundred years. Physics forceps are one possible alternative, aiming to perform less traumatic and more predictable extractions.
Aim: The aim of study was to compare the effectiveness of physics forceps as an alternative, less traumatic, tool to the conventional extraction forceps.
Materials and methods: All patients in the study were split into two groups: 26 patients in whom conventional extraction forceps were used (a control group) and 28 patients in whom we used physics forceps (a study group). For each group, we assessed the success of the extraction, the buccal cortical plate preservation, pain experience, and early wound healing.
Results: There was no statistically significant difference in extraction success scores between the two groups. Physics forceps extractions preserved the buccal cortical plate in 81.1% of instances, while traditional forceps extractions did so in 71.8%. The patients in the study group reported less pain on the seventh day. At 10 days, the study group had a marginally higher proportion of completely healed extraction wounds.
Conclusions: Atraumatic extractions preserve more hard and soft tissues at the extraction site. Physics forceps are a tool similar to the well-known conventional extraction forceps. They provide for somewhat better results in most extractions.

Authors: Song Hongbiao , Tang Zhaoxiang , Collins Clar 
Published: April 2024

Abstract
GE has worked with Genesis to develop a semi-submersible Floating Offshore Substation (FOSS) solution (810MW, HVAC) for USA west coast with 1100-mter water depth. This concept design is based on the metocean data in Morro Bay Area, California (CA). The 1100-meter water depth and swell metocean (long period wave) give rise to extra technical challenges for floating OSS design, especially for the dynamic cable design.
The developed semi-submersible Floating Offshore Substation (FOSS) solution (810MW, HVAC) has been further validated and confirmed by one wave basin test performed at Oceanide (South-France) during July 2023.
As one part of one complete FOSS solution, how to transport and install (T&I) FOSS at California west coast site has been investigated. This California site condition brings special challenges for the T&I, such as the port infrastructure limitation, etc.
The main purpose of this paper is to discuss the recommended transportation and installation (T&I) methodology for the FOSS, which includes the load-out, dry transport, discharge, mooring preset, wet tow, mooring hookup and dynamic cable installation.
The recommended T&I methodology is mainly based on the fabrication base case, that the FOSS topside has been integrated onto the hull at the fabrication yard.
Based on the recommended T&I methodology presented in this paper, it can be concluded that the GE FOSS (810MW, HVAC) can be transported from Asian fabrication yard to California west coast, and installed.
Case Study: Space-Industry Robotics Technology Leveraged to Realize Significant Improvements in Offshore Safety and Sustainability
Authors: Beveridge Ivana , Yamokoski John 
Published: April 2024

Abstract
Historically, subsea vehicles were controlled by communications through a tether, which presents several challenges including a limited range of motion, deployment and retrieval, cost and logistics, and environmental impact. These challenges inspired the development of a new generation of robotic solutions seeking to transform the industry into an economically efficient and environmentally sustainable model.
Autonomous systems are increasingly providing economic and environmental value, such as intelligent robots with subsea applications in energy, defense, transportation, and aquaculture. Combined with AI capabilities, these robots can make subsea work more sustainable.
The paper presents findings from a robotics company established in 2014 in Texas by NASA-bred entrepreneurs. Today, the company exports its robotic services and vehicles internationally. Findings offer a first-hand insight into the development of the interconnected, purpose-built ecosystem of surface and subsea robots. The technology leverages autonomous behaviors, acoustic communications, over-the-horizon networking, force/torque controllable electric manipulation, AI and machine learning, and multimodal 3D workspace sensors. It is inspired by NASA's command and control approach for robots in space. When this framework is applied to subsea systems, it removes the need for the tether through the autonomous capabilities onboard the robotic assets. Removing the tether has a cascading effect on support infrastructure and ultimately results in a reduction of on-site human support, thereby making operations safer.
This new subsea robotics approach helps deliver an economically viable and environmentally sustainable model that significantly reduces operational footprints, operating costs, and GHG emissions, while improving offshore health, safety, and environmental exposure. New approaches to subsea technology could help develop complex autonomous ecosystems and serve as proof of concept for developing commercially viable technologies.
Precise Stochastic Fatigue Life Assessment of Umbilicals and Power Cables
Authors: Arnholm C. , Varadhi M. 
Published: April 2024

Abstract
Increasing activity within offshore wind energy and related installations has raised the focus on the integrity and fatigue life of power cables and umbilicals. A limiting factor for assessing fatigue life has been the lack of efficient and precise computational tools that are not overly conservative. This paper presents features of an advanced computational method implemented in a new tool for accurately assessing the integrity and predicting the fatigue service life of dynamic power cables and umbilicals.
Internal friction between components of power cables and umbilicals creates hysteretic stress responses that global finite element analysis (FEA) does not capture. It is widespread practice to assess irregular wave global responses through time-domain FEA and local cross-sectional analysis through specialized FEA tools. The global responses are combined with results from local FEA tools like UFLEX (developed by Sintef Ocean) to obtain accurate stresses capturing local effects, including friction induced hysteresis. Kongsberg Maritime introduced an innovative method in Hoen-Sorteberg et. al 2013 (OTC-24328-MS), employing tension-dependent hysteresis for flexible risers. This methodology has now been expanded to support power cables and Umbilicals.
Fatigue life assessment of unbonded structures like power cables and umbilicals involves analyzing various elements in the cross-section at multiple locations and orientations to accurately identify critical hotspots, considering load sharing and local friction between components like steel tubes, armor wires, and conductor strands exhibiting complex stress hysteresis behavior. Local FEA provides essential data to account for these complex hysteresis effects and linear stress factors like tension and component bending. The improved methodology and its implementation permit comprehensive stochastic fatigue assessment of power cables and umbilicals without imposing an undue computational burden. The outcome leads to more precise and often substantially prolonged fatigue life predictions by mitigating the inherent conservatism found in methods based on regular waves.
This paper demonstrates the practicality of the methodology and robustness through real-world implementation. The local-global approach yields precise stress levels comparable to direct local model analysis but with markedly enhanced computational efficiency. Previous similar methods suffered from limitations in both stress accuracy and computational speed, limiting their practical utility. A significant advantage is that this computational tool operates independently without needing specific FEA software integration, allowing users to utilize data from various sources.
