Structural and functional insights into the G protein-coupled receptors: CB1 and CB2
Authors: Brust Christina A. , Swanson Matthew A. , Bohn Laura M.
Published: August 2023

The cannabinoid receptors CB1 and CB2 mediate a variety of physiological processes and continue to be explored as desirable drug targets. Both receptors are activated by the endogenous endocannabinoids and the psychoactive components of marijuana. Over the years, many efforts have been made to make selective ligands; however, the high degree of homology between cannabinoid receptor subtypes introduces challenges in studying either receptor in isolation. Recent advancements in structure biology have resulted in a surge of high-resolution structures, enriching our knowledge and understanding of receptor structure and function. In this review, of recent cannabinoid receptor structures, key features of the inactive and active state CB1 and CB2 are presented. These structures will provide additional insight into the modulation and signaling mechanism of cannabinoid receptors CB1 and CB2 and aid in the development of future therapeutics.
Novel pharmacological approaches in abdominal aortic aneurysm
Authors: Puertas-Umbert Lídia , Almendra-Pegueros Rafael , Jiménez-Altayó Francesc , Sirvent Marc , Galán María , Martínez-González José , Rodríguez Cristina
Published: August 2023

Abdominal aortic aneurysm (AAA) is a severe vascular disease and a major public health issue with an unmet medical need for therapy. This disease is featured by a progressive dilation of the abdominal aorta, boosted by atherosclerosis, ageing, and smoking as major risk factors. Aneurysm growth increases the risk of aortic rupture, a life-threatening emergency with high mortality rates. Despite the increasing progress in our knowledge about the etiopathology of AAA, an effective pharmacological treatment against this disorder remains elusive and surgical repair is still the unique available therapeutic approach for high-risk patients. Meanwhile, there is no medical alternative for patients with small aneurysms but close surveillance. Clinical trials assessing the efficacy of antihypertensive agents, statins, doxycycline, or anti-platelet drugs, among others, failed to demonstrate a clear benefit limiting AAA growth, while data from ongoing clinical trials addressing the benefit of metformin on aneurysm progression are eagerly awaited. Recent preclinical studies have postulated new therapeutic targets and pharmacological strategies paving the way for the implementation of future clinical studies exploring these novel therapeutic strategies. This review summarises some of the most relevant clinical and preclinical studies in search of new therapeutic approaches for AAA.
Laboratory bistatic synthetic aperture radar coherent change detection investigation
Authors: Hagelberg Alexander , Andre Daniel , Finnis Mark
Published: August 2023

Synthetic Aperture Radar (SAR) Coherent Change Detection (CCD) allows for the detection of very small scene changes. This is particularly useful for reconnaissance and surveillance as small changes such as vehicle tracks can be identified. In some situations, it is desirable to rapidly collect repeat pass SAR images for use in change detection, and multistatic geometries may facilitate this. Such repeat passes may however have significant baselines, particularly for satellite‐based platforms, though CCD products are reliant on high coherence for good interpretability. This work investigates the sources and levels of incoherence associated with bistatic SAR imagery with increasing baselines using simulations and measured laboratory data.
An active learning method based on result quality evaluation for printed circuit board computed tomography image segmentation
Authors: Song Baojie , Qiao Kai , Yang Jie , Shi Shuhao , Chen Jian , Yan Bin
Published: August 2023

Element detection is a key step in non‐destructive testing of printed circuit board (PCB) based on computed tomography (CT). In recent years, some image segmentation methods based on deep learning have shown great potential in the element segmentation task of PCB CT images, and greatly improved the efficiency and accuracy. However, since image segmentation is based on pixel‐level classification, the annotation of training data is difficult and costly. Aiming at this problem, the authors proposed a new active learning method based on the integration of relevant information about segmentation tasks and data variance. In this method, the Result Quality Evaluation Module (RQEM) proposed by us is used to generate task‐related information, and an adversarial network is used to generate the difference information between samples and the initial labelled data. Finally, the two parts of information are fused and used as the standard of data selecting. In the PCB CT image element segmentation task, the authors only need to select 12.7% of the whole training set with their proposed method to make Mean Intersection Over Union (MIOU) reach 79.7, which has reached 95% of the optimal performance of 83.7. The in‐depth analysis also verifies the effectiveness and stability of the authors’ method.

Authors: Ji Qiulang , Wang Jihong , Ding Caifu , Wang Yuhang , Zhou Wen , Liu Zijie , Yang Chen
Published: August 2023

In recent years, convolutional neural networks (CNN)‐based automatic segmentation of medical images has become one of the hot topics in clinical disease diagnosis. It is still a challenging task to improve the segmentation accuracy of the network model with the large variation of pathological regions in different patients and the fuzzy boundary of pathological regions. A Dual‐path Multi‐scale Attention Guided network (DMAGNet) for medical image segmentation is proposed in this paper. First, the Dual‐path Multi‐scale Attention Fusion Module (DMAF) is proposed as a novel skip connection strategy, which is applied to encode semantic dependencies between high‐level and low‐level channels. Second, the Multi‐scale Normalized Channel Attention Module (MNCA) based on the atrous convolution, normalization channel attention mechanism, and the Depthwise Separable Convolutions (DSConv) is developed to strengthen dependencies between channels. Finally, the encoder–decoder backbone employs the DSConv, as well as the pretrained Resnet34 block is combined in the encoder part to further improve the backbone network performance. Comprehensive experiments on brain, lung, and liver segmentation tasks show that the proposed DMAGNet outperforms the original U‐Net method and other advanced methods.
Passing‐yielding intention estimation during lane change conflict: A semantic‐based Bayesian inference method
Authors: Cui Mingyang , Liu Jinxin , Zheng Haotian , Xu Qing , Wang Jiangqiang , Geng Lu , Sekiguchi Takaaki
Published: August 2023

Intention estimation has been widely studied in lane change scenarios, which explains a vehicle's behaviour and implies its future motion. However, in dense traffic, lane‐changing is more tactical and interactive. Due to the conflict between merging vehicles and adjacent vehicles, driving intentions become interdependent which fuses passing and yielding. In addition, lane change occurs without a fixed location. Drivers should be aware of each other's intentions along conflict process, and take instant responses. To address these challenges, this paper proposes semantic‐based interactive intention estimation (SIIE), to understand driving intentions during lane change conflict. The problem is addressed by combining driving semantics with probability inference model based on dynamic Bayesian network (DBN). Firstly, the DBN is modelled for the interaction process with Condition‐Intention‐Behaviour relationships. Secondly, the semantics are extracted from the lane change conflict and are inferred with observation methods. Thirdly, SIIE is trained and verified with real‐world driving data. The intention estimation results are demonstrated, and then utilized for multi‐modal motion identification and trajectory prediction. Lane change in dense traffic requires interactive cognition of driving intentions, the findings of this research shall inspire future studies into related scenarios, and promote interactive driving technologies.
Optimal load demand forecasting in air conditioning using deep belief networks optimized by an improved version of snake optimization algorithm
Authors: Jiang Haichang , Li Minghai , Fathi Gholamreza
Published: August 2023

Air conditioning systems play a vital role in maintaining comfortable indoor environments, particularly in hot and humid climates. However, these systems consume a significant amount of energy, making load demand forecasting an important aspect of energy management. In this study, the authors propose a novel approach for load demand forecasting in air conditioning systems using a hybrid deep belief network (HDBN) and an improved snake optimization algorithm (ISOA). The HDBN is a machine learning technique that combines deep learning and probabilistic graphical models to capture complex patterns in the input data. The ISOA is a nature‐inspired optimization algorithm that mimics the movement of a snake to search for optimal solutions. The proposed approach is evaluated using real‐world data from a commercial building in a hot and humid region. The results show that the proposed HDBN/ISOA approach outperforms other commonly used techniques in terms of accuracy. The proposed approach can be used to optimize energy consumption and reduce costs in air conditioning systems.

Authors: Neumann M. , Avakyan A. , Doroshenko V. , Santangelo A.
Published: August 2023

Context. We present a new catalogue of high mass X-ray binaries (HMXBs) in the Galaxy that we call the Galactic High Mass X-ray Binary Catalogue (XRBcats), which improves upon the most recent of such catalogues. We include new HMXBs discovered since previous publications and revise the classification for several objects previously considered HMXBs or HMXB candidates. The catalogue includes basic information (e.g. source names, coordinates, types), other data (e.g. distance and X-ray flux estimates, binary system parameters), and other characteristic properties of the 169 HMXBs catalogued. We also present finding charts in several bands from the infrared to hard X-rays for each object.

Aims. The aim of this catalogue is to provide a list of all currently known Galactic HMXBs, including basic information on both compact objects and non-degenerate counterpart properties (where available). We also include objects tentatively classified as HXMBs in the literature and give a brief motivation for the classification in each case.

Methods. The catalogue is compiled based on a search of known HMXBs and candidates in all publicly available databases and literature published before May 2023. The relevant properties in various wavelength bands were collected for all objects, either from the literature or using data provided by large-scale surveys. For the latter case, the counterparts in each individual survey were found by cross-correlating positions of identified HMXBs with relevant databases.

Results. An up-to-date catalogue of Galactic HMXBs is presented to facilitate research in this field. Our goal was to collect a larger set of relevant HMXB properties in a more uniform way compared to previously published works.
The concept of a fast reactor with liquid metal fuel in tungsten capsules
Authors: Okunev Viacheslav
Published: August 2023

The concept of a dual-purpose high-power nuclear reactor is proposed. One of the goals is the production of electricity, the other is the production of high-potential thermal energy. It is proposed to use liquid fuel based on waste uranium and plutonium extracted from the spent fuel of VVER reactors (purified from the 238Pu isotope). The fuel is in sealed tungsten capsules. Lead extracted from thorium ores is used to cool the reactor. The electrical power of the reactor is 3.3 GW. The layout of the reactor is identical to the BREST-OD-300 reactor under construction. The analysis of emergency modes from among ATWS (anticipated transients without scram) is carried out. The reactor is reliable and safe. The maximum temperature of a high-temperature reactor coolant is close to the boiling point of lead. By the nature of the change in the maximum temperatures of the core components, the reactor occupies an intermediate position between a reactor with solid metallic fuel and a reactor with cermets based on UN-PuN and metal uranium nanopowder.

Published: August 2023

The main reason for the emergence of the operational characteristics of tractor diesel engines is the uneven fuel consumption. Fuel equipment is one of the most responsible systems of diesel engines. The purpose of the study was to improve the fuel efficiency of an agricultural tractor diesel engine by using an injector sprayer. Modernization of the needle of the atomizer of the fuel injector is carried out by directing its guiding surface of the helical groove at an angle α, advancing the direction of the axisymmetric fuel pressure. This includes the fuel injector needle, as it is likely to be skewed, stuck, and dependent. The novelty of this design is protected by the patent of the Russian Federation RU 2231673. To assess the fuel efficiency, natural experiments of a diesel engine with serial and modernized injectors were carried out. The introduction of new technical equipment in the fuel equipment has led to the achievement of diesel engine power by 8 … 12% and the rate of retention of fuel consumption by 3 … 4%.

Authors: Liamasov A K , Denisov K E , Biriulin M A
Published: August 2023

Hydropower plants (HPPs) contribute a significant share of Russia’s electricity generation. With the prospects of developing this sector and harnessing the hydroenergy potential, it is necessary to consider methods for modernizing hydroelectric installations. This article examines a new method for regulating active (Pelton) turbines based on modifying the nozzle flow rate through the ejection of spent liquid from the runner using a jet pump. The relevance of this solution lies in the potential to increase the operational duration of high-head pumped-storage hydropower plants (PSHPPs) and improve reliability by eliminating or reducing the intensity of operation of the regulating needle in the guide apparatus. Various structural configurations for incorporating the jet pump into the hydrosystem of HPPs/PSHPPs with Pelton hydro turbines are discussed. Parallel and series configurations offer specific advantages and disadvantages. A methodology for determining the expression to calculate the parameters of the injecting device, depending on the turbine’s characteristics, is presented based on a mathematical model of the jet pump with a central nozzle.

Authors: Shibaeva Tatjana G , Sherudilo Elena G , Mamatmurodov Khurshed B , Parshina Anastasia E
Published: August 2023

The study was aimed on the assessment of extracts from four arctic brown seaweeds (Ascophyllum nodosum, Fucus vesiculosus, Laminaria digitata and Saccharina latissimi) as stimulators of plant growth. Seaweeds were collected from the Rebalda Bay of the White Sea in August 2021. Extracts were obtained by isopropanol maceration method, then vacuum-dried at 40°C and stored at -4°C. Protein, polyphenols, chlorophyll, carotenoids, alginates, mannitol and polysaccharides contents of extracts were determined. Wheat and cucumber seedlings were used as test plants. Extracts from all four brown seaweeds enhanced growth, accelerated development of plants and increased chlorophyll content in leaves. Plant responses to seaweed extracts were concentration-dependent. Higher concentration of A. nodosum and F. vesiculosus extracts inhibited plant growth possibly due to higher phenolic content. The results show that investigated seaweed extracts obtained by isopropanol maceration method with subsequent drying and freezing have proven to be effective in plant growth stimulation.
Sustainable development: Is an impartial equilibrium between human needs and natural resources existent?
Authors: Kolokolov Yury , Monovskaya Anna
Published: August 2023

Social-economic plans are originally illusive under growing repetition/activity/duration of unexpected atypical weather phenomena recently occurred. The paper discusses conceptually this aspect of the sustainable development taking into account the limits of good-for-human-activities reproduction of a local seasonal weather pattern depending on directions of the dynamics evolution in the corresponding climate system. The discussion is developed from the fundamentals of the theory of nonlinear dynamics. This view clarifies indicators to existence/absence of sustainable development grounded on the insuperable physical laws. The corresponding novel method of identification of these indicators (denoted by the method of transients) is formulated and potentiality of its realization is investigated by processing the meteorological data of temperature observation. It is illustrated that a way to consider soundly non-stationary nonlinear dynamics opens once the perverted partition onto “weather” and “climate” is eliminated and nonlinear, regulatory and inertial properties of dynamical processes in local climate systems become analyzed integrally. Finally the conclusions are summarized.

Published: August 2023

Environmental protection in the Republic of Uzbekistan with a developed chemical, petrochemical, metallurgical and pharmaceutical industries is an important problem of our time. To solve it, a domestic copper-chromite catalyst “Chemex-203” was previously developed, which was operated for a long time in an energy-saving reversible reactor RKR- 10 in the process of catalytic neutralization of ventilation emissions of highly toxic styrene, toluene and acetone vapors on the territory of the “Hobos-TAPO” joint venture in Tashkent. This paper is devoted to solving a two-sided environmental problem - obtaining copper-chromite catalysts using toxic wastes of local industry for thermal catalytic neutralization of gaseous emissions of volatile organic compounds typical of the pharmaceutical and chemical industries. The conducted studies make it possible to 100% replace imported aluminum hydroxide in the composition of the aluminum-titanium carrier for the copper-chromite catalyst for the complete oxidation of toxic emissions with the intermediate product of the processing of spent alumina adsorbent, including gel-like pseudoboehmite. The resulting catalyst is distinguished by good mechanical strength, chemical and thermal stability and allows highly efficient neutralization of combustible toxic substances in the composition of various gas emissions.

Published: August 2023

The efficiency of biocomposting of bottom silt deposits was evaluated in laboratory conditions. The biocomposting process is reproduced taking into account the main technological parameters and using lowland peat, microbial concentrate and vermiculture as basic components. The composition of the microbial concentrate includes strains of the genera Bacillus spp., Clostridium spp., Pseudomonas spp., causing biosolubilization of a complex organomineral substrate - bottom sediments. The productive line Eisenia foetida Savigny (Lumbricidae) was used as a vermiculture. The evaluation of the efficiency of biocomposting was carried out according to agrochemical characteristics. The greatest effect on the preservation of biogens was obtained during the fermentation of bottom sediments with the participation of microbial concentrate. An increase in the content of N to 1.10%, P – to 0.54%, K – to 0.42% was achieved. The use of vermiculture caused an increase in organic matter – up to 42.1% and humus – up to 14.6%. The results of the experiment allow us to consider biocompost and vermicompost obtained using bottom sediments as a source of elements necessary for plant growth and development.

Sektorenübergreifende Versorgungsverläufe von
Patient*innen mit kolorektalem Karzinom in
Sachsen-Anhalt
Authors: Beutner Katrin , Medenwald Daniel , Meyer Gabriele
Published: August 2023

Einleitung Die kleinräumige Gesundheitsversorgung Sachsen-Anhalts
wird als disparat beschrieben, da sich Regionen mit guter Versorgungsstruktur
und zunehmend unterversorgte Regionen gegenüberstehen. Defizite beim
sektorenübergreifenden Therapiemanagement gefährden die
poststationäre Versorgung in ländlichen Gebieten. Ziel der
Arbeit war es, anhand von GKV-Routinedaten beispielhaft für
Patient*innen mit kolorektalem Karzinom sektorenübergreifend die
Versorgungssituation in Sachsen-Anhalt über den Zeitraum von
Diagnosestellung bis zu einem Jahr poststationär zu analysieren und zu
prüfen, ob Versorgungsunterschiede zwischen Versicherten aus
städtischen und ländlichen Regionen auszumachen sind.

Methoden Die Studienpopulation umfasst 13.218 Versicherte der AOK
Sachsen-Anhalt mit kolorektalem Karzinom der Jahre 2010–2014. Die
abgerechneten Versorgungsleistungen von Krankenhäusern und ambulanten
Ärzt*innen wurden in Bezug auf den Wohnort (Stadt oder Land) der
betroffenen Patient*innen betrachtet. Die Ermittlung der
Überlebenszeiten erfolgte nach Kaplan & Meier und die Analyse
erklärender Variablen auf das Überleben mittels
Regressionsanalyse nach dem Cox-Proportional-Hazards-Model.

Ergebnisse Unterschiede zwischen städtischen und
ländlichen Regionen wurden bei den involvierten Facharztgruppen im
ambulanten Bereich sowie bei der Versorgung in Darmkrebszentren deutlich. Der
Anteil der Versicherten mit onkologischen Zusatztherapien war sehr gering,
sodass nur in Ansätzen von leitliniengerechter Therapie ausgegangen
wird. Die Analyse offenbarte einen signifikanten Überlebensvorteil
für Versicherte aus der Großstadt im Vergleich zu Versicherten
aus ländlichen Regionen, wofür v. a. eine frühere
Diagnosestellung, ein jüngeres Alter, weniger Komorbiditäten und
eine adäquatere Krebstherapie ursächlich sind.

Schlussfolgerung Es bedarf einer Optimierung der Versorgungsstrukturen und
-prozesse, die eine frühe Diagnosestellung und barrierefreie
Inanspruchnahme adäquater Therapien ermöglicht.
Aus der Krise zur Empathie: Martin Gumperts Vermächtnis für die Medizin des 21. Jahrhunderts
Authors: Keim Ulrike , Schröder Hartmut , Mildenberger Florian G.
Published: August 2023

Die 1920er Jahre gelten in der medizinhistorischen Überlieferung als das klassische Krisenjahrzehnt im 20. Jahrhundert, von dem aus der Weg der deutschen Medizin mehr oder weniger direkt in den nationalsozialistischen Untergang geführt habe. Doch die „Krisis der Medizin“ führte mitnichten zwangsläufig in den Strudel aus Eugenik und Rassenhass, sondern begünstigte auch eine Rückbesinnung auf ethische Traditionen und zeitlose Werte. Dies zeigt sich in besonderem Maße am Beispiel des Arztes Martin Gumpert (1897–1955). Gumpert agierte als politisch denkender und handelnder Arzt, der als Pionier der Entstellungschirurgie, der Gerontologie und Prävention gilt und ein großes Vermächtnis als Dermatologe, Sozialmediziner sowie als Forscher und Journalist hinterlassen hat, dass es heute mehr denn je zu würdigen gilt.

Erweiterte Realitäten (XR) mit den Unterbegriffen Virtual Reality (VR), Augmented Reality (AR) und Mixed Reality (MR) beschreiben interaktive und immersive Technologien, welche die reelle
Welt durch digitale Elemente ersetzen oder diese um solche nahtlos erweitern. Die XR bieten somit ein sehr breites mögliches Anwendungsspektrum in der Medizin. In der Chirurgie und
insbesondere in der Thoraxchirurgie lassen sich XR-Technologien für Anwendungen der Behandlungsplanung, Navigation, Ausbildung und Patienteninformationen nutzbar machen. Solche
Anwendungsfälle befinden sich zunehmend in der Erprobung und müssen hinsichtlich ihrer Wertigkeit evaluiert werden. Wir geben einen Überblick über den Status quo der technischen Entwicklung,
aktuelle chirurgische Einsatzgebiete der XR und blicken in die Zukunft der medizinischen XR-Landschaft mit Integration von künstlicher Intelligenz (KI).
Recycling von chirurgischen Einweginstrumenten – lohnt sich das?

Der deutsche Gesundheitssektor ist für 5,2% der landesweiten Treibhausgasemissionen verantwortlich. Mitverantwortlich hierfür ist die erhebliche Menge an tagtäglich in deutschen
Krankenhäusern erzeugtem Abfall, der die Kliniken zum fünftgrößten Müllproduzenten Deutschlands macht. Die gesetzlichen Regelungen sehen vor, dass ein wesentlicher Anteil der
Krankenhausabfälle, trotz potenzieller Recyclingfähigkeit, energetisch verwertet, also verbrannt, wird. Hierdurch werden einerseits hohe CO2-Emissionen erzeugt und andererseits
wertvolle Rohstoffe dem Kreislauf entzogen. Ziel dieses Projekts war es, anhand von chirurgischen Einweginstrumenten die Machbarkeit des Recyclings von komplexen, kontaminierten
Medizingeräten nachzuweisen.

Inkludiert wurden häufig eingesetzte chirurgische Einweginstrumente, die potenziell als Elektroschrott recycelt werden konnten. Diese Instrumente wurden wischdesinfiziert und anschließend
krankenhausintern sterilisiert. Nach der Sterilisation konnten die Geräte in Rücksprache mit der Umweltbehörde als Elektroschrott klassifiziert und durch ein Entsorgungsunternehmen extern
maschinell recycelt werden. Durch Schredder- und Sortiermaschinen wurden die Instrumente in die einzelnen Fraktionen Kabel, Kunststoffe, verschiedene Metalle und Platinen aufgeteilt und zu
Sekundärrohstoffen weiterverarbeitet.

In den ersten 6 Monaten (09/2022–03/2023) wurden 239 kg Material recycelt anstatt verbrannt. Dies entspricht einer Einsparung von 545 kg CO2e. Der Metallanteil lag bei ca. 50%
des Gesamtgewichts. Hinzu kamen 30% recycelbare Kunststoffe, sodass eine Recyclingquote von 80% erreicht wurde. Die laufenden Kosten für das Recycling lagen nach Abzug der Einnahmen bei
1,90 €/kg. Damit ist Recycling in diesem Modell 3,9-mal so teuer wie die Verbrennung. Eine Umfrage unter dem beteiligten OP-Personal ergab eine hohe Zufriedenheit mit dem Recyclingprojekt
und einen geringen Mehraufwand von < 5 min.

Wir konnten zeigen, dass das Recycling kontaminierter Einweginstrumente in Absprache mit den staatlichen Behörden möglich ist und hierdurch Abfallverbrennung vermieden und
CO2-Äquivalente eingespart werden können. Einschränkend auf die Umsetzbarkeit solcher Projekte wirken derzeit noch die deutlich höheren Kosten des Recyclings und die
Verpflichtung der krankenhausinternen Dekontamination. Um dies zu ändern, ist der Gesetzgeber gefragt, die derzeitigen Vorschriften zu überdenken und die Hersteller an den Recyclingkosten
zu beteiligen, um das riesige Recyclingpotenzial vollständig auszunutzen.

Based on recent data, a total number of about 29 000 patients with adrenal
insufficiency can be calculated for Germany, and about 1500 fatalities due to
adrenal crises have to be expected within the next decade. Management of adrenal
crises is still unsatisfactory. The objectives of this study were to establish
consensus for diagnostic criteria, prevention strategies, and treatment
recommendations for adrenal crises. The study was conducted from January 2022 to
April 2023, using Delphi technique. Four rounds of questionnaires were sent to
45 experts, selected by a coordinating group on behalf of the adrenal section of
the German Society of Endocrinology. The survey was implemented online using the
REDCap web application. Responses were captured anonymously. During the Delphi
process the expert panel developed diagnostic criteria to identify patients
likely to have an adrenal crisis. Education about adrenal insufficiency among
patients as well as non-endocrine medical personnel were regarded as highly
important. It was suggested that recommendations for the management of adrenal
insufficiency have to be simplified and made widely available. This study
provides pragmatic strategies to identify and treat patients prone to adrenal
crisis, thereby highlighting the need for an improved management of patients
with adrenal insufficiency.

Objective To assess the prevalence of sonographic signs in women with uterine sarcoma.

Materials and Methods A systematic review and meta-analysis were performed. Five electronic databases were searched from inception to June 2022 for all studies allowing calculation of the prevalence of sonographic signs in women with uterine sarcoma. Pooled prevalence with 95% confidence intervals was calculated for each sonographic sign and was a priori defined as “very high” when it was ≥ 80%, “high” when it ranged from 80% to 70%, and less relevant when it was ≤ 70%.

Results 6 studies with 317 sarcoma patients were included. The pooled prevalence was:

Conclusion Solid component, irregular walls of cystic areas, and singular lesions are signs with very high prevalence, while inhomogeneous echogenicity of solid component, anechoic cystic areas, and absence of calcifications are signs with high prevalence. The remaining signs were less relevant.
Pelvic Venous Disorders: An Update in Terminology, Diagnosis, and Treatment
Authors: Clark Meghan R. , Taylor Amy C.
Published: August 2023

Pelvic venous disorder (PeVD) is a term that encompasses all the interrelated causes of chronic pelvic pain (CPP) and perineal/lower extremity varicose veins of pelvic venous origin historically known as nutcracker syndrome, pelvic congestion syndrome, and May-Thurner syndrome, resulting in a more precise diagnosis that accounts for the underlying pathophysiology and anatomy. PeVD manifests as CPP with associated vulvar and lower-extremity varicosities, left flank pain and hematuria, and lower extremity pain and swelling secondary to obstruction or reflux in the left renal, ovarian, or iliac veins. This article will focus specifically on the most current nomenclature, evaluation, and management of CPP of venous origin.
Recanalization of Proximal Fallopian Tube Obstruction in the Treatment of Infertility
Authors: Mody Priya , Salazar Gloria , Kohi Maureen P.
Published: August 2023

Infertility affects approximately 15% of patients worldwide, with up to 40% of cases attributed to tubal disease, and up to 25% of those being proximal fallopian tube obstruction (FTO). Evaluation of tubal patency can be performed via laparoscopic chromopertubation, hysterosalpingography, or hysterosalpingo-contrast-sonography (HyCoSy). In patients with proximal tubal obstruction, fallopian tube recanalization (FTR) can result in up to 100% technical success rate with pregnancy rates of 12.8 to 51%. More pregnancies occur when oil-soluble contrast media are used versus water-soluble contrast media. Complications of FTR are rare and include tubal perforation, ectopic pregnancy, and pelvic infection. Reocclusion of fallopian tubes may occur in 20 to 50% of patients; however, FTR may be repeated in these cases. Overall, FTR is underutilized in the treatment of infertility secondary to proximal FTO and it can obviate costly and time-consuming assistive reproductive techniques such as in vitro fertilization in some patients, as well as decreasing physical and emotional stress.
The Role of Helicobacter pylori and Small Intestinal Bacterial Overgrowth in Parkinson's Disease
Authors: Justich Maria Belen , Rojas Olga L. , Fasano Alfonso
Published: August 2023

Parkinson's disease (PD) is a common neurodegenerative disorder whose etiology remains largely unexplained. Several studies have aimed to describe a causative effect in the interactions between the gastrointestinal tract and the brain, for both PD pathogenesis and disease course. However, the results have been controversial. Helicobacter pylori and small intestinal bacterial overgrowth (SIBO) are theorized to be agents capable of triggering chronic proinflammatory changes with a possible neurotoxic effect, as well as a cause of erratic L-dopa response in PD patients. This review evaluates the individual and possibly synergistic influence of H. pylori and SIBO on PD, to provide an opportunity to consider prospective therapeutic approaches.
